Anninou, Ioanna. "Consumer confusion : a test of the behavioural perspective model." Thesis, Cardiff University, 2013. http://orca.cf.ac.uk/56902/.
Full textAbstract:
In light of the increasing academic and practical importance of consumer confusion, more theoretical and empirical inquiries are necessary in order to comprehend this concept. This study extends the notion of confusion by adopting the idea of self-based rules. Confusion can be defined as a self-based track (or better a rule for the lack of rules and norms, a special case of anomy). As a rule, there is a differing language that can be used to describe it– the first, extensional, deals with confusion as an overall response to physical and social stimuli and the other, intentional, deals with it in terms of individual understanding and beliefs. This study uses the theoretical principles of the Behavioural Perspective Model (BPM) as its primary device. The current state of the BPM dictates the use of an extensional language (BPM-E). The model will be extended and placed within the framework and study of an intentional explanation (BPM-I). The explanatory or interpretative role that confusion can play in these models will be described. Specific research hypotheses that correspond to these explanations have been developed. In order to implement these objectives a main quantitative survey (N=260) which provided data on 520 consumer situations, has been informed by a meaningful in the produced results pilot-exploratory study (N=7) and multiple qualitative (N=10) and quantitative (N=56) pilot tests and discussions with knowledgeable and lay participants. Multiple regression and ANOVA indicate significant main effects when Mehrabian and Russell’s affective scales and different kinds of confusion (similarity-complexity) are used to predict approach-avoidance behavioural responses. Additionally, support is provided for the patterns expected from the affective and behavioural variables when these are applied to other situations beyond the original eight contingency categories of the BPM. The main contribution of this study lies with the inclusion of an aversive consequence of shopping situations in the BPM and the extension of the model towards embracing and applying intentionality. Overall, this study supports the supposition put forward by Foxall (2004; 2007a; 2007b; 2013) that the intentional BPM can add and extend the explanatory power of the extensional model.

Genetic testing offers disease diagnosis and other information based on genetic material provided by an individual. Direct to consumer genetic tests bypass clinicianadministered tests in favour of direct sales and usage by consumers. The relative newness of consumer genetic testing to the South African market provides an opportunity for understanding the factors that would drive adoption of these products. An established technology acceptance model was enriched with factors important to clinical genetic testing and individual innovativeness. The model was tested through an online questionnaire with a nonprobability sample of 109 individuals. Factors including performance expectancy, social influence and discrimination concerns, were found to exhibit significant influence on consumers’ behavioural intention to use consumer genetic tests. These findings provide a theoretical framework of individuals’ attributes of importance for marketing and sales of consumer genetic tests. CopyrightDissertation (MBA)--University of Pretoria, 2010.

Fortified blended foods (FBFs), which are the mixture of cereals and legumes fortified with micronutrients, have been widely used as supplementary foods for vulnerable populations such as infants and young children in developing countries around the world. The evaluation of current FBFs showed limited evidence on their effectiveness in treating childhood malnutrition, resulting the several recommendations on processing and formulation changes to improve their quality and ability to meet nutritional needs. Sensory properties are one of the important determinants for the success of the new FBFs. Therefore, sensory testing was conducted to determine the potential of novel FBFs to be used as supplementary food compared with FBF currently used in food aid programs. Descriptive sensory analysis was performed on novel FBFs along with the traditional FBF (Corn soy blend plus; CSB+) to determine sensory characteristics of each FBF. Results showed that novel FBFs had more pronounced toasted characteristics and higher sweetness than CSB+, due to the higher temperature during extrusion process and the addition of sugar in the novel formulation. In addition, novel FBFs that had higher amount of legumes (e.g. soybean, cowpea) in their formulations, especially for all sorghum cowpea blends, showed higher intensity in beany characteristics. Sensory shelf-life testing showed that novel FBFs could have shelf lives at least 2 years with no detection of off-note characteristics and these was comparable to the shelf life of the current FBF (CSB+). Sensory testing was also performed with target populations: children who eat the food and care givers who prepare it, during a 20-week field trial to determine the acceptability and preference of novel FBFs and current FBF. Results showed that all novel FBFs were highly preferred or accepted by children, even though, some of them might need longer time and more exposures to allow children to have more experience and be familiar with the food before being satisfied or preferred that food. In contrary, CSB+ that had bland flavor tended not to be well accepted and highly preferred by children compared to novel FBFs. Moreover, giving children more opportunities to consumed food prepared from CSB+ did not help to improve its acceptability or preference. Data from household visits and interview sessions showed that porridges prepared from novel FBFs required less cooking time than CSB+ and no additional ingredients needed to be added compared to CSB+ where sugar and milk were common additions. Finding from this research indicated that novel FBFs have high potential to be used successfully as supplementary food with comparable shelf life, and higher acceptability and preference to FBF currently used in food aid programs. In addition, the simple cooking of novel FBFs make them valuable to caregivers who have limited time and access to energy sources and nutrient-rich ingredients.

Full textAbstract:
ABSTRACT
The purpose of the present study was to explore the potential influence of direct-to-consumer genetic test results of a pre-adoptive foster child on the decision of the prospective adoptive foster parents to finalize or disrupt their adoption of the foster child. A quantitative survey was conducted using a sample of foster parents with three distinct statuses as a foster parent. They included, foster parents in the process of adopting their foster child, foster parents awaiting placement of a foster child in their home, and individuals in the process of completing training to become foster parents. The study participants were from a foster family agency that specializes in foster adoptions and all study participants had indicated they wanted to adopt a foster child. The foster family agency has two locations, one in Orange County and the other in San Bernardino County. Study data was collected through the use of a self-report questionnaire at five different foster family agency events. Twelve original survey questions were designed to measure three core areas: knowledge of prospective adoptive foster parents on the information direct-to-consumer genetic testing can provide; attitudes of prospective adoptive foster parents regarding the use of direct-to-consumer genetic testing as a pre-adoption screening tool; and, if direct-to-consumer genetic test results of a foster child influences the decision of prospective adoptive foster parents to finalize or disrupt a foster adoption. Using SPSS software to analyze data, descriptive statistics, Pearson correlation analyses were conducted between the three different foster parent statuses and the four questions designed to measure the core area of if direct-to-consumer genetic test results of a foster child influences the decision of prospective adoptive foster parents to finalize or disrupt a foster adoption. More than half of the survey participants, identified as women (n=39, 54.9%) and 32 (23.9%) identified as men. Results showed that there was a significant relationship found between the direct-to-consumer genetic test results of a foster child to influence the prospective adoptive foster parent to stop adoption proceedings for the child with the status of foster parents awaiting placement of the first foster child into their home.

Full textAbstract:
The thesis asks whether there is a role for competition law and policy in the music industries. It is argued that there is a need for updated competition policy in order to safeguard both end consumer welfare and the competitive process in these markets, characterised by fast-paced developments and business model innovation. Indeed, the past two decades saw the music industries undergo seismic changes, as even the term 'music industries' was not in use as such before the advent of the internet era and the decline in sales of recordings in physical format. Soon it became obvious that the traditional music industry's end consumers had chosen to migrate to alternative methods of consumption, complementing and substituting between several products for music, such as the digital format, the live concert ticket, and the overall 'music experience'. End consumers chose to completely by-pass the product on offer, meaning the recording of popular music in physical format, as provided top-down by a few multinational record companies, which the thesis identifies as an oligonomy. As alternative business models emerged in the music industries, the members of the oligonomy became followers of end consumer demand, remaining stuck in their notion that the end consumer remains the passive, mass market. Addressing this era as an era of market failure helps to identify the role of the end consumer within the business model of the music industry and to understand emerging trends and patterns in the music industries. Indeed, technological and copyright developments in the late nineteenth century enabled the hardware industries to morph into the recorded music industry, operating under the same business model of copyright exploitation. It follows that the market deriving from this business model is a market prone to monopolisation, resulting in a homogeneous product, designed and delivered top-down to the mass market. The resulting product was not only foreclosed by the few members of the oligonomy, but the operating business model made it impossible for the competition authorities to justify concerns. When the technology allowed for it, the creeping market failure came to the limelight and the end consumer started by-passing the oligonomy to gain access to the foreclosed content, generating consumer demand-driven business models. This translated into business model innovation. To illustrate, the thesis investigates the trial-and-error relationship between the competition authorities of the US, the EU, the UK and the old business model, addressing the failure to appreciate the bottleneck around the creative output that was being created, and the need to safeguard consumer welfare. To compare, the thesis also examines cases in the new business model era, observing the stance of competition authorities towards consumer demand generated business models. The thesis concludes with the affirmation of the need to design welfare enhancing competition policy, which places the end consumer in the forefront. To achieve this, the thesis proposes the consultation of the relevant business model literature.

This investigation sought to bridge the communication and marketing fields by applying schema theory (Bartlett, 1932) to advertisement information processing. A theoretical framework was developed which described how television commercials are remembered. Specifically, the theory hypothesized that: (a) recall of product brand will be significantly higher in the sample of participants who are exposed to the commercials emphasizing brand early on in their format, than the participants who view the commercials stating the product's brand name in the latter half of the commercials, and (b) individuals who see the brand name formatted commercials will have significantly higher levels of commercial information recognition than the individuals exposed to the commercials that do not state the brand name at the onset. The results of the study provided intial support for the proposed framework and suggested that brand name formatted commercials will generally enhance recall and significantly impact recognition.

Full textAbstract:
Il prosciutto cotto è un alimento presente nella dieta degli italiani, che lo consumano più di ogni altro salume. Il D. M. del 21/09/2005, che ne disciplina produzione e vendita, lo classifica in tre diverse categorie merceologiche (Prosciutto cotto o Standard, Prosciutto cotto Scelto, Prosciutto cotto Alta Qualità). Il lavoro svolto presso il Dipartimento di Scienze e Tecnologie Agro-Alimentari dell’Università di Bologna su 92 consumatori di prosciutto cotto ha permesso di studiare abitudini, gusti, aspettative dei soggetti intervistati e di verificare la loro capacità di distinguere prosciutti cotti appartenenti alle differenti categorie. A tale scopo è stato progettato un questionario strutturato secondo il modello RATA con una sezione per valutare i profili emozionali dei prodotti in esame conforme al metodo EmoSemio. Il gruppo di consumatori intervistati era composto da soggetti con età compresa tra 19 e 70 anni, frequenza di consumo di prosciutto cotto pari a 1-3 volte al mese e maggior familiarità con l’Alta Qualità. I risultati ottenuti hanno evidenziato l’ottima capacità percettiva dei consumatori, che hanno descritto i campioni in modo analogo al panel di esperti, che in precedenza aveva valutato gli stessi campioni. La chiara discriminazione riscontrata da parte dei consumatori tra i prosciutti Standard e Alta Qualità, però, non sempre si è tradotta in una preferenza per il prodotto della categoria migliore. I risultati relativi alla valutazione dello stato emozionale erano in linea con il gradimento: per i prodotti più graditi l’intensità delle emozioni positive era più alta. Infine, quasi tutti gli attributi scelti dal panel sono stati compresi e valutati allo stesso modo dai consumatori, risultando efficaci e, talora, comunicabili. Questo studio ha contribuito a fornire gli elementi per la comprensione del profilo di gradimento del prosciutto cotto al consumo ed ha confermato l'utilità del metodo RATA e dell’EmoSemio.

This essay focus on the development and implementation of a model to evaluate consumer perceived value. Initially, itâs discussed the perceived value concept, its importance under strategy and marketing perspectives and its relation to price and quality. The model is presented, considering each step to be followed: perceived quality study of brands in the market; consumerâs perceptions of competitorâs prices; and the value map development, defined considering the relation quality/price for each brand in the market. The model applicability was tested in a soft drink category study in Fortaleza market, based in a survey with 400 consumers. The application shows that the model, built under consumerâs point of view, can provide a descriptive panel of competitorâs positions and relevant information to be used in market diagnoses. The information and the descriptive panel mentioned can be useful, not only in strategic analyses, but also in price formulations.Esta dissertaÃÃo està centrada no desenvolvimento e utilizaÃÃo de um modelo para a avaliaÃÃo do valor percebido pelos consumidores.

Full textAbstract:
Inledning: Surdeg är idag en trend som fångats av många och de flesta bagerier ochdagligvarubutiker säljer bröd som kallas för surdegsbröd. Ett traditionellt surdegsbröd är ettbröd där surdegen används som enda hävningsmedel i brödet. Syfte: Syftet var att undersöka skillnader i sensoriska egenskaper, utifrån ettkonsumentperspektiv, samt GI-värde mellan surdegsbröd, jästbröd och bröd bakat på bådesurdeg och jäst. Material och metod: Metoderna som användes var två olika konsumenttester för att bestämmaskillnader mellan de tre bröden, och en in vitro-metod för att bestämma GI-värde. Resultat: Resultatet visade att konsumenter känner skillnad mellan surdegsbröd och jästbrödoch mellan surdegsbröd och bröd bakat på både surdeg och jäst men däremot inte mellanjästbröd och bröd bakat på både surdeg och jäst. Den syrliga smaken i surdegsbröd minskar ombrödet bakas på både surdeg och jäst. GI-mätningen genom in vitro-metoden visade att brödetbakat på både surdeg och jäst hade lägst GI medan surdegsbrödet hade högst. Slutsats: Ett bröd bakat på både surdeg och jäst är mer likt ett jästbröd än ett surdegsbröd. In vitro-metoden är inte den mest tillförlitliga för att undersöka skillnader i GI för justsurdegsbröd samtidigt som surdegsbrödets pH-värde kan ha varit för högt för att kunna sänkabrödets GI-värde. Inga slutsatser kunde därför dras från GI-mätningen.Introduction: Sourdough is today a trend that has been caught by many and most bakeries andgrocery stores sell bread called “Sourdough bread”. Traditional sourdough bread is bread wherethe sourdough is used as only leavening agent. Purpose: The purpose was to examine differences in sensory attributes, from a consumerperspective, and glycemic index between sourdough bread, yeast bread and bread baked withboth sourdough and yeast. Material and Method: The methods used were two different consumer tests to determinedifferences between the three breads, and an in vitro-method for determining the glycemicindex. Result: The results showed that consumers can sense the difference between sourdough breadand yeast bread and between sourdough bread and bread baked with both sourdough and yeastbut not between yeast bread and bread baked with both sourdough and yeast. The sourish tasteof sourdough bread decreases if the bread is baked with both sourdough and yeast. Theglycemic index measurements by the in vitro-method showed that the bread baked with bothsourdough and yeast had the lowest glycemic index value whilst the sourdough bread had thehighest. Conclusion: Bread baked with both sourdough and yeast more resembles yeast bread thansourdough bread. The in vitro-method is not the most reliable for examining differences inglycemic index value for sourdough bread meanwhile the pH-value of the sourdough breadmay have been too high to be able to lower the glycemic value of the bread. No conclusionscould therefore be made from the glycemic index measurements.

Mais da metade da população no mundo vive em povoados e cidades. Estes lugares correspondem àqueles que têm sido imediata e diretamente influenciados pela globalização. Nesse cenário, muitas empresas multinacionais estão alterando seus portfólios de marcas em favor de marcas globais; essa situação faz com que surja o conceito de cultura de consumo global - conjunto de símbolos relacionados ao consumo e comportamentos que são comumente entendidos, mas não, necessariamente, compartilhados pelos consumidores e negócios ao redor do mundo. Isso dependeria da suscetibilidade para a cultura de consumo global (SCCG), uma característica ou traço latente dos consumidores que varia através dos indivíduos e é refletido no desejo dos consumidores ou tendências para a aquisição e uso de marcas globais. Esse traço, pela literatura revisada, compreenderia a conformidade com a tendência de consumo global, percepção de qualidade, prestígio social, responsabilidade social, credibilidade de marca, risco percebido e custo de informação armazenada. É nesse contexto, portanto, que se insere a presente tese, ao caracterizar e verificar o impacto dos traços latentes da suscetibilidade para a cultura de consumo global (SCCG) de consumidores em distintas culturas (países) na aquisição de marcas globais. A pesquisa empírica consistiu de um survey com uso de questionário pela Internet, direcionado a estudantes universitários e profissionais procedentes de carreiras de ciências empresariais em distintos países. Os dados, um total de 467 questionários válidos, foram analisados sob duas abordagens metodológicas: (1) Teoria Clássica dos Testes (TCT) e (2) Teoria de Resposta ao Item (TRI). Ambas as abordagens justificadas pelos constantes questionamentos, identificados na literatura, ao uso de técnicas estatísticas aplicadas a escalas assumidas como intervalares, mas que na realidade são ordinais (tipo Likert). Os resultados foram divididos em três partes. A primeira, ao nível do modelo de mensuração, constou a relação positiva dos construtos subjacentes ao construto de SCCG. A segunda, ao nível do modelo estrutural, verificou que o construto de SCCG antecede a intenção de compra de uma marca global. Por fim, em terceiro lugar, sob a abordagem da TRI, escolhida por apresentar maiores vantagens sobre a TCT, constatou-se que não existem efeitos invariantes nas relações do framework proposto quando comparados quatro países, mas sim existem, em alguns casos, quando comparados pares de países. De forma geral, a presente tese traz uma contribuição teórica-empírica ao propor um framework mensurável da suscetibilidade para a cultura de consumo global, que reflete o desejo dos consumidores para adquirir e usar marcas globais. A tese é finalizada com a descrição das conclusões, implicações, limitações e direcionamentos futuros sobre o framework proposto e salienta a utilização da abordagem TRI como complemento à abordagem da TCT, amplamente usada em pesquisa sobre o comportamento do consumidor.More than half of the world population lives in towns and cities which have been directly and immediately influenced by globalization. In this scenario, many multinational companies are changing their brand portfolios in favor of global brands. This situation arises the concept of global consumer culture - a set of symbols related to consumption and behaviors that are commonly understood, but not necessarily shared, by consumers and businesses around the world. This concept depends on the susceptibility to global consumer culture (SCCG), a characteristic or latent trait of consumers that varies across individuals and is reflected in the consumers willingness or trends to purchase and consume global brands. According to the literature reviewed, this trait is related to the trend of global consumption, quality perception, social prestige, social responsibility, brand credibility, perceived risk and cost of information stored. It is in this context that this thesis will distinguish and verify the impact of latent traits of the susceptibility to global consumer culture (SCCG) of consumers from different cultures (countries) in the acquisition of global brands. For this purpose, a questionnaire was administered via the Internet, through a snowball sampling, aimed at students and business professionals from different countries. The data, a total of 467 valid questionnaires were analyzed under two approaches: (1) Classical Test Theory (CTT) and Item Response Theory (IRT). Both are justified by the constant literature questioning about the use of statistical techniques applied to scales assumed to be interval, but which in reality are ordinal (Likert). The results were divided into three parts. The first one, at the level of the measurement model, it was found a positive relationship between the subjacent constructs to the SCCG construct. The second one, at the structural model level, found that the SCCG construct precedes the global brand purchase intention. Finally, the TRI approach was chosen because it presents major advantages over the TCT, as there is no invariant effects on the framework relations proposed compared to the four countries, but there are some cases when compared to pairs of countries. Overall, this thesis provides a theoretical and empirical contribution due to a measurable framework of the susceptibility to global consumption culture, which reflects consumers\' desire to acquire and use global brands. The thesis concludes stating the findings, implications, limitations and future directions of the proposed framework and emphasizes the use of the IRT approach as a complement to the TCT approach, widely used in consumer behavior.

Mestrado em MarketingAlthough a considerable amount of research into beer consumer behavior has been conducted in several countries, no publicly available such study performed in Portugal has been found. The aim of this research is to understand young consumers' perceptions regarding six brands available in Portuguese retailers and to compare the results with other studies. In this research the author developed a conceptual framework and defined hypotheses, permitting an answer to the purpose of this investigation. Different techniques for collecting data such as surveys and experimentations were used and analysed statistically. The findings suggest that the presence of the brand and packaging are determinant in the formation of consumers' sensorial expectations and play a central role in consumers' evaluation, even if those attributes are not recognized as more important in consumers'perspectives. The majority of participants were unable to Recognize their favourite brand in the blind-test evaluation, and the two brands that were rated in last positions in the survey climbed to the top when they were not identifiable, even if in consumers'perspectives the taste is the most important attribute when choosing a beer. The main beneficiaries of the research should be breweries and, more precisely, marketing and brand managers because it provides important insights into the attributes young consumers value most and suggests strategies for marketing and advertising campaigns. The research can also provide an academic contribution because it specifies the processes to conduct blind test experimentations and suggests further studies based on the investigation results. It also, once again, makes obvious the importance of brand awareness.

Full textAbstract:
This study was approached with a desire to move forward the body of knowledge concerning environmental research as it pertains to the hospitality industry. The endeavor was undertaken with the belief that concern and awareness about the environment is not a passing fad but a fundamental shift in society. In order for any business to survive it must keep up with changes and meet the demands of consumers. The research efforts in this study were aimed at establishing the validity and reliability of a consumer behavior model specifically related to environmental behavior.
The purpose of this dissertation was to evaluate a consumer's intention to stay in a hotel based on the environmental strategies used by that hotel. Hines (1984) developed a conceptual environmental consumer behavior model based on a meta-analysis of literature on environmentally responsible behavior. Hines' conceptual Model of Responsible Environmental Behavior utilized knowledge, abilities, attitudes, personal responsibility and locus of control to predict environmental behavior. The goal of this study was to empirically test an adapted version of Hines' Model of Responsible Environmental Behavior. This adapted version utilized knowledge, attitudes and perceived self-efficacy to predict consumers' intentions to purchase a night's stay in a hotel.
Canonical correlation analysis was used to test the relationship between intention and each of the variables (knowledge, attitudes and perceived self-efficacy) in Hines' model. The multivariate test of significance revealed that each variable had a positive relationship to intention to purchase. The Hines' Model of Responsible Environmental Behavior was more useful in predicting consumers' intention to purchase a night's stay in a particular hotel than each variable individually. The model tested in this study has laid the foundation for developing a sound environmentally responsible consumer behavior model. The research findings suggest that a hotel implementing environmental strategies can increase business for that hotel.Ph. D.

Full textAbstract:
I Sverige kastreras inte bagglamm. Detta bidrar till djurvälfärd och etiska mervärden för lammköttskonsumenten. Samtidigt finns studier som pekar på att könsmogna intakta bagglamm ger kött med handjurssmak som inte uppskattas av konsumenter. I Sverige har mindre konsumentundersökningar genomförts på magert kött från bagglamm av olika ålder utan att hitta skillnader i konsumentpreferens. Bland praktiker i branschen finns en erfarenhet som vittnar om att smakskillnaden huvudsakligen sitter i djurets fettvävnad och betydelsen av detta har inte undersökts närmare. I en försöksdesign med färskkorv kan råvarumängder och djurslag justeras för att analysera skillnader orsakade av kön, ålder och fettslag. Syftet med detta arbete är att genom sensoriska undersökningar och fettsyraanalys utvärdera effekten av ålder och kön på ätkvalitet i färskkorv baserad på svensk lammköttsråvara. Studien baserar på färskkorv producerade i en faktoriell design med hjälp av i branschen vanligt förekommande köttsorteringar som undersöks via beskrivandetest, konsumenttest och fettsyraprofilering. Data från undersökningarna analyseras med variansanalys och Pearsons korrelationstest. Resultaten från studien visar att färskkorvens sensoriska profil påverkas av valet av köttråvara. Yngre bagglamm på 4 månader bidrar till en lösare konsistens och en saltare smak hos färskkorven medan tacklamm på 10 månader ger en tätare textur och en fettkvalitet vars egenskaper resulterar i en kvardröjande känsla i munnen. Skillnaderna kan delvis förklaras av att fettsyrasammansättningen varierar med ålder och kön och att tacklammen har ett fett med högre halt av stearinsyra, ett fastare fett som i studien, inte uppskattas av konsumenten. De äldre bagglammen har ett fett med högre andel palmitinsyra vilket i resultatet är positivt korrelerat med konsumenters totala gillande. Andra viktiga faktorer för hög konsumentpreferens är fastare konsistens och en tydlig lammsmak, variabler som i studien kan kopplas till äldre bagglamm.

Previous issue date: 2006-01-01Objetivos: Avaliar a segurança, reprodutibilidade, a acurácia em estimar o consumo de oxigênio pico e o valor prognóstico do teste graduado da caminhada (“shuttle walk test”), em comparação com o teste da caminhada de seis minutos em pacientes com insuficiência cardíaca crônica sintomática. Métodos: Avaliamos prospectivamente 63 pacientes com insuficiência cardíaca. Todos os pacientes realizaram um teste cardiopulmonar, dois testes graduados da caminhada, dois testes da caminhada de seis minutos e foram acompanhados por um período médio de 14,01 ± 7,8 meses. Resultados: A idade média dos pacientes foi 51,28 ± 10,26 anos, a fração de ejeção 24,05 ± 5,69% e o consumo de oxigênio pico 16,79 ± 5,76ml/kg/min. As distâncias percorridas, no 1º e no 2º teste graduado da caminhada foram 414,44 ± 122,87 e 422,85 ± 119,18m, respectivamente, atestando sua ótima reprodutibilidade (ρ = 0,979). O teste mostrou-se seguro. A distância percorrida no teste graduado da caminhada foi menor em relação ao teste da caminhada de seis minutos (p < 0,001) e o índice de percepção do esforço foi maior (p = ,029). Houve forte correlação entre as distâncias percorridas em ambos os testes (r = 0,88) e entre o teste graduado da caminhada e o consumo de oxigênio pico (r = 0,79). A acurácia em estimar um consumo de oxigênio pico menor ou igual a 14ml/kg/min foi semelhante nos dois testes. As distâncias percorridas em ambos os testes não foram preditoras de eventos e somente o consumo de oxigênio pico foi preditor de sobrevida livre de eventos. Conclusões: O teste graduado da caminhada é reprodutível, seguro e apresenta boa correlação com o teste da caminhada de seis minutos e com o consumo de oxigênio pico; mostrou-se sensível e específico em estimar um consumo de oxigênio pico inferior a 14ml/kg/min. Entretanto não foi capaz de fornecer informações sobre o prognóstico dos pacientes desta amostra.
Objectives: To access the safety, reproducibility, and accuracy at estimating peak oxygen consumption and prognostic value in shuttle walk test compared to six-minute walk test in patients with symptomatic chronic heart failure. Methods: Sixty-three patients with heart failure were prospectively assessed. All patients underwent cardiopulmonary exercise test, two shuttle walk tests, and two six-minute walk tests. Patients were followed-up for a mean period of 14.01 ± 7.8 months. Results: Mean age of patients was 51.28 ± 10.26 years old, ejection fraction was 24.05 ± 5.69%, and peak oxygen consumption was 16.79 ± 5.76ml/kg/min. Distances walked in the first and second shuttle tests were 414.44 ± 122.87 and 422.85 ± 119.18m, respectively, which proved their great reproducibility (ρ = 0.979). The test was also safe. Distance walked in the shuttle walk test was shorter compared to that walked in six-minute walk test (p < 0.001), the perception of effort rate was greater (p = 0.029). There was a strong correlation between the distances walked in both tests (r = 0.88), and between shuttle walk test distance and peak oxygen consumption (r = 0.79). Accuracy to estimate peak oxygen consumption smaller or equal to 14ml/kg/min was similar in both tests. Distances walked in both tests were not predictors of events and peak oxygen consumption was the only predictor of event free survival. Conclusions: Shuttle walk test is reproducible, safe, presenting a satisfactory correlation with six-minute walk test, and with peak oxygen consumption; it has been proved sensitive and specific in estimating peak oxygen consumption lower than 14ml/kg/min. However, it could not provide information on the prognosis of the patients from this sample.

Thesis (MA)--University of Stellenbosch, 2000.ENGLISH ABSTRACT: The study investigates text properties of the consumer-advice magazine article in Xhosa within the framework of the genre-based approach to literacy and writing. The view of writing as component of the communication competence component in Grabe and Kaplan's (1996) theory of writing is assumed. It is argued that the analysis of (non-fictional) genres is a core ability in terms of the specifications of Curriculum 2005 for outcomes-based language teaching for writing skills. The term genre as it is used within genre theory refers to a (non-fictional) text which has an identifiable social (or cultural) purpose, an identifiable form (including beginning, middle and end) and specific constrains on the possible deviations allowed in its form. This study will examine seven BONA magazine articles to establish what identifiable generic properties can be attributed to these genretexts. The cognitive move structure of these magazine articles on consumer advice will be analysed to determine whether a typical move structure occurs for this genre. The text-linguistic properties of the various magazine articles will be investigated invoking Grabe and Kaplan's model of text-structure. In particular, properties like pronominal reference conjunctive devices, which contribute to text coherence and cohesion will be considered as well as lexical choices as a reflection of communicative purpose. Finally, the study will briefly address the issue of the significance of the genre-text knowledge underlying writing skills as the relevant kind of knowledge to be developed in terms of the specifications of outcomes-based language teaching in Curriculum 2005. The kind of analytic skills exemplified in the examination of the Xhosa magazine articles are therefore necessitated for accomplishing the outcomes for writing. The nationale for developing such analytic abilities with respect to writing skills is to empower learners to be competent writers in their future career lives.
AFRIKAANSE OPSOMMING: Hierdie studie ondersoek die teks-struktuur eienskappe van die verbruikers-advies tydskrifartikel in Xhosa binne die raamwerk van die genre-gebaseerde benadering tot geletterdheid en skryfvaardigheid. Die beskouing van skryfvaardigheid as 'n komponent van die kommunikasievaardigheid komponent in Grabe en Kaplan (1996) se teorie van skryfvaardigheid word aanvaar. Daar word geargumenteer dat die analise van nie-fiksie (of nie-literêre) genres 'n kemvermoë is in terme van die spesifikasies van Kurrikulum 2005 vir uitkoms-gebaseerde taalonderrig van skryfvaardigheid. Die terme genre, soos dit gebruik word in genre-teorie verwys na 'n (nie-fiksie) teks met 'n identifiseerbare sosiale, kommunikatiewe of kulturele doelstelling, 'n identifiseerbare vorm (insluitende 'n begin, middel en einde) en spesifieke beperkings rakende die toelaatbare afwykings in vorm. Die studie sal sewe BONA tydskrifartikels ondersoek om te bepaal watter identifiseerbare eienskappe toegeskryf kan word aan hierdié genre-tekste. Die kognitiewe skuif-struktuur van hierdie tydskrifartikels oor verbruikersadvies salontleed word om te bepaal watter tipiese skuif-struktuur voorkom vir hierdie genre. Die teks-linguistiese eienskappe van die verskillende tydskrifartikels salondersoek word deur die model van Grabe en Kaplan te gebruik. In die besonder, eienskappe soos voornaamwoordelike verwysing, voegwoord-meganismes wat bydra tot tekskoherensie en kohesie salondersoek word, asook leksikale (woord) keuses as 'n refleksie van die skrywer se kommunikatiewe doelstelling. Laastens, sal die studie kortliks vraagstukke ondersoek rakende die belang van die genreteks kennis wat onderliggend is aan skryfvaardigheid as die relevante soort kennis wat ontwikkel moet word in terme van die spesifikasies van uitkoms-gebaseerde taalonderrig in Kurrikulum 2005. Die soort analitiese vaardighede wat na vore kom in die ondersoek van die Xhosa tydskrifartikels word genoodsaak ten einde die uitkomste vir skryfvaardigheid te bereik. Die motivering vir die ontwikkeling van sodanige analitiese vermoëns ten opsigte van skryfvaardigheid is om leerders te bemagtig om 'n goeie skryfvaardigheid te hê in hulle toekomstige beroepe.

Egglestone, Corin. "The informational aspects of direct-to-consumer genetic tests." Thesis, Loughborough University, 2013. https://dspace.lboro.ac.uk/2134/16403.
Full textAbstract:
Background: Direct-to-consumer (DTC) genetic tests are tests sold directly to consumers, normally without the involvement of healthcare professionals, which aim to provide consumers with their relative genetic risk for various complex diseases. Providers claim that this information will enable and encourage consumers to improve their health behaviour in order to reduce their likelihood of contracting diseases for which they are at an increased genetic risk. However, there are many criticisms and concerns about DTC genetic tests in the literature. Two common concerns are the lack of positive effects, and possible negative effects, that the information generated by the tests may have on consumers health behaviour and health anxiety, and the identified poor quality of information provision on the websites of providers of DTC genetic tests. Although the literature contains some research in these areas it is noticeably limited and occasionally contradictory. Aim and Methods: The aim of the research was to investigate the informational aspects of direct-to-consumer genetic tests, including the provision of information by the companies, consumers information needs and information-seeking behaviour and the effect of the information generated by the tests on health behaviour and health anxiety. The research consisted of three studies: a survey of 275 consumers and potential consumers of DTC genetic tests, in-depth email interviews with 36 consumers of DTC genetic tests and a content analysis of the information provided on all identified providers websites. Results: Positive or neutral changes in health behaviour were identified in a large minority of respondents who had been exposed to genetic risk information, along with the mechanisms by which the information prompted or contributed to change. A minority reported a change in health anxiety, mainly but not exclusively a decrease, with mechanisms again identified. Consumers reported a wide variety of information needs, the most common of which were information to do with the coverage and accuracy of the tests. The provision of information on providers websites varied considerably, both between and within providers, but was generally poor. However, most consumers used other sources alongside these websites, the most common of which was blogs. Conclusions: The results suggest that concerns about possible negative effects of the information generated by the tests are unfounded and that a large minority of consumers have improved health behaviour and decreased health anxiety after purchase. The results also suggest that concern about information provision on providers websites is justified; although this is mitigated by consumers general use of other sources alongside the websites, it is likely that a substantial number of consumers do not have access to enough information to give fully informed consent to the test.

Personalisierung ist ein wichtiger Bereich des Internet Marketings, zu dem es wenige experimentelle Untersuchungen mit großen Teilnehmerzahlen gibt. Für den erfolgreichen Einsatz von Empfehlungsverfahren sind umfangreiche Daten über das Käuferverhalten erforderlich.
Diesen Problemstellungen nimmt sich die vorliegende Arbeit an. In ihr wird das Shop-übergreifende individuelle Käuferverhalten von bis zu 126.000 Newsletter-Empfängern eines deutschen Online-Bonussystems sowohl mittels ausgewählter Data-Mining-Methoden als auch experimentell untersucht.
Dafür werden Prototypen eines Data-Mining-Systems, einer A/B-Test-Software-Komponente und einer Empfehlungssystem-Komponente entwickelt und im Rahmen des Data Minings und durch Online-Feldexperimente evaluiert.
Dabei kann für die genannte Nutzergruppe in einem Experiment bereits mit einem einfachen Empfehlungsverfahren gezeigt werden, dass zum einen die Shop-übergreifenden individuellen Verhaltensdaten des Online-Bonus-Systems für die Erzeugung von Empfehlungen geeignet sind, und zum anderen, dass die dadurch erzeugten Empfehlungen zu signifikant mehr Bestellungen als bei der besten Empfehlung auf Basis durchschnittlichen Käuferverhaltens führten.
In weiteren Experimenten im Rahmen der Evaluierung der A/B-Test-Komponente konnte gezeigt werden, dass absolute Rabattangebote nur dann zu signifikant mehr Bestellungen führten als relative Rabatt-Angebote, wenn sie mit einer Handlungsaufforderung verbunden waren.
Die Arbeit ordnet sich damit in die Forschung zur Beeinflussung des Käuferverhaltens durch Personalisierung und durch unterschiedliche Rabatt-Darstellungen ein und trägt die genannten Ergebnisse und Artefakte bei.

Being innovative in a more and more competitive market can be anything but trivial. There is a complex variables system to be taken into account throughout an innovation process, and hardly ever will there be enough data to support a research or decision. It is always possible to turn to human inference, or cognitive bias, when enough data is not available, or when time for decision-making is scarce. Consumer Insight technique has been used for this research purpose and aimed at lowering cognitive bias, seeking to find out what are consumers' wishes and needs so that decision-making or innovation could be supported. This paper proposes to mitigate the influence of cognitive bias, by means of data analysis techniques, in search for patterns which can identify opportunities to give both decision-making and search for innovation some support. In order to achive this purpose, unstructured data from 26.514 telephone talks had in a big financial market company between 01.12.2016 e 31.12.2016 have been used. Analysis has been carried out with the transcript from voice into text concomitantly with Text Mining and Social Network analysis. The results have led us to identify main client demands from a sales perspective, cancellation resquest, as well as the reason for inefficiency in offering new products from elements of higher centrality identified in the word association networks. It is implied that the combined use of analytical techniques applied to unstructured data may give rise to findings in which cognitive bias is lower.
Em um mercado cada vez mais competitivo, ser inovador pode ser um diferencial, porém não é uma atividade trivial. Existe um sistema de variáveis complexas que deve ser considerado ao longo de um processo de inovação e nem sempre há dados suficientes que suportem uma pesquisa ou decisão. A inferência humana, ou viés cognitivo, pode ser uma alternativa quando não existem dados suficientes ou quando o tempo para a tomada de decisão é menor que o necessário. A técnica de Consumer Insight foi utilizada nesta pesquisa com o objetivo de diminuir o viés cognitivo, buscando descobrir os anseios e necessidades do consumidor, para suportar o processo de tomada de decisão ou inovação. Este estudo apresenta uma proposta para mitigar a influência do viés cognitivo, a partir de técnicas de análise de dados, em busca de padrões que possam identificar as oportunidades para suportar o processo decisório ou a busca pela inovação. Neste trabalho foram utilizados dados não estruturados de 26.514 conversas telefônicas realizadas no período de 01/12/2016 a 31/12/2016, provenientes de uma empresa do mercado financeiro. A metodologia analítica consistiu na transcrição de voz para texto e no uso associado de técnicas de Text Mining e Análise de Redes Sociais. Os resultados obtidos permitiram identificar as principais demandas dos clientes na perspectiva de vendas, pedido de cancelamento e a razão da ineficiência das ofertas de novos produtos, a partir dos elementos de maior centralidade identificados nas redes de associação de palavras. Implica-se que o uso combinado de técnicas analíticas em dados não estruturados pode permitir a obtenção de achados com menor influência do viés cognitivo.

Full textAbstract:
Conselho Nacional de Desenvolvimento Científico e TecnológicoThis work presents the prototyping and analysis of new multiplier architectures under the physical level of abstraction. Circuits recently presented in the academic community are analyzed and compared against the state of the art. The new architectures operate on signed multiplication and maintain the pure form of an array multiplier. These architectures are extended for radix-2m encoding, where m is the number of the bits, which leads to a reduction of the number of partial lines. The proposed approach significantly improves the state of the art, enabling gains in performance and power consumption. Such aspects are attractive for the implementations of the new multipliers in the physical level. For the most of the systems, functionality tests are used in order to verify if a circuit is functionally equivalent to a given specification. These types of tests have to be the first part of the development of the circuit. Thus, we have developed in this work a flow of the circuit analysis. This flow covers since the functional tests, passing through the stages of physical synthesis in transistors level and FPGA, until the prototyping in Silicon of the architectures. In this work, we have used the same test vectors in all the stages of the project which involves, since the verification of the logical functionality until the extraction of the power consumption in physical level.
Este trabalho apresenta a prototipação e análise de novas arquiteturas de circuitos multiplicadores digitais sob o ponto de vista físico. São analisados circuitos recentemente apresentados no meio científico e comparados com o estado da arte. As novas arquiteturas efetuam operações de multiplicação com sinal e mantêm a mesma regularidade de um multiplicador array convencional. As arquiteturas podem operar com números na base 2m, onde m é o número de bits, o que permite a redução do número de linhas de produtos parciais, tendo-se desta forma, ganhos significativos em desempenho e redução do consumo de potência. Tais características, tornam-se um fator atrativo para as implementações dos circuitos multiplicadores no nível físico. Para a maioria dos sistemas, testes de funcionalidade envolvem a necessidade de provar que o circuito é funcionalmente equivalente a uma determinada especificação. Estes devem ser usualmente os primeiros testes que um projetista deve construir como parte do processo de desenvolvimento do circuito. Desta forma, também faz parte deste trabalho o desenvolvimento de um fluxo de análise dos circuitos. Este fluxo deve percorrer desde os testes funcionais, passando por etapas de síntese física em nível de transistores e em FPGA, até a prototipação em Silício das arquiteturas. Neste trabalho, as arquiteturas de multiplicadores foram submetidas aos mesmos vetores de teste em todas as etapas de projeto, que envolvem desde a verificação da funcionalidade lógica, até a extração do consumo de potência no nível físico.

As indústrias têm deixado de produzir o suco de laranja integral pasteurizado em substituição ao suco de laranja reconstituído devido, principalmente, à dificuldade em se produzir esse tipo de suco durante todo o ano com as mesmas características. Esse trabalho objetivou avaliar sensorialmente esses dois tipos de sucos. Sete provadores selecionados e treinados avaliaram a aparência, aroma, sabor e textura de amostras de suco de laranja utilizando a Análise Descritiva Quantitativa (ADQ). O teste de aceitação pelo consumidor foi realizado com cento e um provadores não treinados, utilizando a escala hedônica e um mapa de preferência foi traçado. A ADQ mostrou que houve diferenças significativas (p<0,05) em relação a: cor amarela, concentrado, aroma laranja, aroma de sumo, sabor de laranja, sabor passado, sabor cozido. Entretanto, não houve diferenças significativas (p>0,05) entre as amostras do suco em relação a: aroma cítrico, aroma cozido, aroma doce, sabor sumo, gosto doce, gosto ácido e encorpado. O suco reconstituído apresentou os atributos com maior intensidade para cor amarela, concentrado, aroma de sumo, sabor passado e sabor cozido em relação ao pasteurizado enquanto esse, o aroma e sabor de laranja foram os atributos mais acentuados. O teste de consumidor indicou que os dois sucos tiveram aceitação parecidas situando-se entre os termos hedônicos indiferente e gostei ligeiramente e o resultado do mapa de preferência mostrou baixa aceitação pela grande maioria dos consumidores de suco. Os dados de HPLC não mostraram diferença entre as amostras de suco analisadas.The industries are allowing to produce the orange juice pasteurized in substitution to the orange juice reconstituted, mainly, the difficulty in producing this type of juice during the year with the same characteristics. This work objectified to evaluate these sensorially two types of juices. Seven selected and trained panelists evaluated the appearance, aroma, flavor and texture of orange juice pasteurized and orange juice reconstituted by Descriptive Quantitative Analysis (QDA). The consumer test and a preference map was done with one-hundred one non-trained panelists through the hedonic test. The QDA showed significant differences (p<0,05) concerning yellow color, concentrate, orange odor, the highest point odor, orange flavor, passed flavor and cooked flavor. However, there was no significant difference (p>0,05) concerning: citric aroma, candy aroma, cooked aroma, supreme flavor, candy taste, acid taste and viscosity. The reconstituted juice presented the attributes with bigger intensity for yellow color, concentrate, the highest point aroma, last flavor and flavor cooked in relation to the pasteurized and this juice, the aroma and flavor of orange had been the more accented attributes. The consumer test indicated that orange juice pasteurized and orange juice reconstituted were acceptance similar placing itself enters the hedonic terms indifferent and liked slightly and the result of the preference map showed low acceptance by majority of the juice consumers. The HPLC data hadnt shown the difference enter the analyzed juice samples.

As doenças oriundas das dislipidemias associadas à obesidade é hoje um dos maiores problemas de saúde pública no Brasil e no mundo, sendo considerada como uma epidemia dos tempos modernos. No Brasil, já se tornou tão preocupante quanto à desnutrição, a hipertensão, diabetes, câncer, colesterol total elevado, coronariopatias, entre outros, já foram relacionados à presença do estilo de vida sedentário bem como os hábitos alimentares, que são grandes fatores de risco na propensão a estas doenças, o que proporcionou um aumento considerável nas taxas de mortalidade mundial. Considerando as doenças que se instalam nos indivíduos devido o sedentarismo e consumo inadequado de nutrientes, como uma das principais causas da mortalidade associada ás doenças crônico não degenerativas, as evidências nos levam a acreditar que qualquer mudança no estilo de vida sedentária é capaz de trazer vantagens principalmente se esta prática estiver associada ao consumo de dieta equilibrada, no qual a dieta alimentar rica em lípides poderá influenciar em sérios fatores metabólicos negativos. Está estabelecida na literatura que sedentarismo associado ao consumo alimentar rico em gorduras a principal causa da obesidade e alteração do peso corporal. Frente o número reduzido de estudos investigando os efeitos do exercício físico em animais submetidos á hiperlipidemia, o objetivo desse estudo foi investigar como variações de lípides na dieta associadas ao efeito de cinco semanas de treinamento físico sobre o peso corporal dos animais, consumo de dieta, gordura corporal e parâmetros séricos (colesterol total, HDL-c e triglicerídeos), frações de peroxidação lipídica e defesa antioxidante do organismo, afim de, portanto analisar se estas possíveis alterações estão associadas a mudanças no perfil lipídico de animais submetidos a dietas normolipídicas e hiperlipídicas...
The diseases from the dyslipidemia associated with obesity is now a major public health problems in Brazil and the world and is regarded as an epidemic of modern times.

Resumo: As doenças oriundas das dislipidemias associadas à obesidade é hoje um dos maiores problemas de saúde pública no Brasil e no mundo, sendo considerada como uma epidemia dos tempos modernos. No Brasil, já se tornou tão preocupante quanto à desnutrição, a hipertensão, diabetes, câncer, colesterol total elevado, coronariopatias, entre outros, já foram relacionados à presença do estilo de vida sedentário bem como os hábitos alimentares, que são grandes fatores de risco na propensão a estas doenças, o que proporcionou um aumento considerável nas taxas de mortalidade mundial. Considerando as doenças que se instalam nos indivíduos devido o sedentarismo e consumo inadequado de nutrientes, como uma das principais causas da mortalidade associada ás doenças crônico não degenerativas, as evidências nos levam a acreditar que qualquer mudança no estilo de vida sedentária é capaz de trazer vantagens principalmente se esta prática estiver associada ao consumo de dieta equilibrada, no qual a dieta alimentar rica em lípides poderá influenciar em sérios fatores metabólicos negativos. Está estabelecida na literatura que sedentarismo associado ao consumo alimentar rico em gorduras a principal causa da obesidade e alteração do peso corporal. Frente o número reduzido de estudos investigando os efeitos do exercício físico em animais submetidos á hiperlipidemia, o objetivo desse estudo foi investigar como variações de lípides na dieta associadas ao efeito de cinco semanas de treinamento físico sobre o peso corporal dos animais, consumo de dieta, gordura corporal e parâmetros séricos (colesterol total, HDL-c e triglicerídeos), frações de peroxidação lipídica e defesa antioxidante do organismo, afim de, portanto analisar se estas possíveis alterações estão associadas a mudanças no perfil lipídico de animais submetidos a dietas normolipídicas e hiperlipídicas...(Resumo completo, clicar acesso eletrônico abaixo)

Full textAbstract:
In this thesis, I investigate permanence through exploring tattoo consumption in terms of the social-historical context of being tattooed. The analysis is based on four years of data collection adopting a grounded theory approach. I present an analysis of how permanence occurs in terms of tattoo consumption, with particular interest in the physical permanence in relation to identity creation. This is set within the framework of Consumer Culture Theory (CCT). The reason for this is twofold, firstly to illustrate the ability of using tattooing as an instrument to investigate permanence within CCT. Secondly, to show the lack of use of the socio-historical perspective within such an investigation, and to show that the use of such data is a valid strategy and which adds depth and context to such an investigation. Furthermore, I suggest that tattoo consumption has become a site of embodied expression that is bounded by physicality, and permanence. I present a typology of tattooed consumers based on levels of commitment and explore in depth two main categories, physicality, and, permanence. I find that the physical permanence is shown through the commitment to tattoo usage. Its permanent nature determines the tattoo as an act of consumption that is dualistic in nature; both accepted, and yet equally rejected, which is seen within the consumers‘ negotiation of its use, in terms of mimicry and placement. Being tattooed represents a form of consumption that contravenes certain rules and norms of society, and yet at the same time is the basis for community membership and adherence to a set of sub-cultural norms and values.

Limited health literacy is a barrier to understanding health information. Simplifying text can reduce this barrier and possibly other known disparities in health. Unfortunately, few tools exist to simplify text with demonstrated impact on comprehension. By leveraging modern data sources integrated with natural language processing algorithms, we are developing the first semi-automated text simplification tool. We present two main contributions. First, we introduce our evidence-based development strategy for designing effective text simplification software and summarize initial, promising results. Second, we present a new study examining existing readability formulas, which are the most commonly used tools for text simplification in healthcare. We compare syllable count, the proxy for word difficulty used by most readability formulas, with our new metric ‘term familiarity’ and find that syllable count measures how difficult words ‘appear’ to be, but not their actual difficulty. In contrast, term familiarity can be used to measure actual difficulty.

O objetivo deste estudo foi verificar a relação entre o limiar ventilatório dois (LV2) e o consumo máximo de oxigênio (VO2max) como preditores de tolerância ao esforço em jogadores de futebol. O LV2 e o VO2max foram medidos a um terço de encerramento da temporada. Uma amostra de sessenta atletas futebolistas do sexo masculino, distribuídos nas seguintes posições: (14 zagueiros [23%], 14 laterais [23%], 19 meio campistas [32%] e 13 atacantes [22%]) menos os goleiros. A média de idade era de 20,8 ± 2,8 anos; massa corpórea de 71,9 ± 7,6 kg e estatura de 178 ± 6,5 cm foram avaliadas num estudo transversal. Todos eram assintomáticos, não fumantes, não faziam uso de qualquer medicamento e eram livres de qualquer tipo de distúrbio neuromuscular, cardiovascular, respiratório e circulatório. A média de treinamento no período competitivo consistiu de 10 horas semanais. Todos os jogadores eram de clubes profissionais da primeira divisão do Estado de São Paulo e estavam registrados na Federação Paulista de Futebol.Todos foram submetidos à avaliação cardiorrespiratória e metabólica, utilizando-se analisador metabólico de gases (CPX/D, MedGraphics, EUA) acoplado a eletrocardiógrafo (Max Personal, Marquette, EUA), ambos os sistemas computadorizados. A determinação da capacidade física máxima foi verificada em esteira rolante (Inbramed, ATL10200, BRA) utilizando-se protocolo escalonado contínuo (1 km.h-1 a cada dois minutos) e inclinação fixa de 3%. Os seguintes resultados verificados e os parâmetros utilizados foram: VO2max = 58,8 ± 4,48 mL.kg-1.min-1; VO2LV2 = 49,6 ± 4,96 mL.kg-1.min-1; TTMAX = 1073 ± 124,5s; TTLV2 = 713 ± 106,0s. Análise de regressão linear demonstrou correlação positiva entre o TTMAX vs. VO2max (r = 0,473;p<0,001); VO2LV2 vs. VO2max (r = 0,691; p<0,001); TTLV2 vs. VO2max (r = 0,545; p <0,001); TTMAX vs. TTLV2 (r = 0,560; p < 0,001) e entre TTLV2 vs. VO2LV2 (r = 0,610; p< 0,001). Concluindo, a potência aeróbia máxima associada ao aumento do consumo de oxigênio no LV2, são preditores de uma maior capacitação aeróbia em jogadores de futebol. O melhor parâmetro preditor de tolerância ao exercício em todas as posições foi à relação VO2LV2 vs. VO2max.The aim of this study was to investigate the relationship between the ventilatory threshold two (VT2) and maximum oxygen consumption (VO2max) as predictors of exercise tolerance in soccer players. VT2 and VO2max were measured when one-third of the soccer season still remained. A sample of sixty male soccer players, distributed in the following position: (14 central-defenders [23%], 14 fullbacks [23%], 19 midfielders [32%] and 13 forwards [22%]) less the goalkeepers, were evaluated a cross-sectional study. The mean age was 20.8 ± 2.7 years, body mass: 71.9 ± 7.62 kg and height: 178.1 ± 6.5 cm. All were asymptomatic, non-smokers, they did not use any medication and were free from any kind of neuromuscular disorder, cardiovascular, respiratory and circulatory. In the competitive season, the average training week consisted of 10 hours practice and games. All the players were professional clubs of the first division of the State of Sao Paulo and were registered in the Paulista Football Federation. All of them underwent a cardiopulmonary and metabolic exercise test evaluation. To this end we used a gas explorer (CPX/D, breathbybreath Medgraphics, Saint Paul, MN, USA) coupled to an electrocardiograph (Max Personal, Exercise Testing System, Marquette, USA). Both systems were computerized. The maximum exercise test was performed on a motor-driven treadmill (Inbramed, ATL-10200, Porto Alegre, BRA), using the incremental continuous exercise protocol. The athletes started the race with 8 km.h-1 and increased speed of 1 km.h-1 every two minutes with fixed slope at 3%. In all tests there was verbal encouragement. The results verified and the parameters used were: VO2max = 58.8 ± 4.48 mL.kg-1.min-1; VO2VT2 = 49.6 ± 4.96 mL.kg-1.min-1; MAXTT = 1073 ± 124.5s; TTVT2 = 713 ± 106s. Linear regression analysis in male soccer players showed positive correlation between the VO2max vs. MAXTT to exercise (R = 0.473; p < 0.001); VO2VT2 vs. VO2max (R = 0.691; p < 0.001); TTVT2 vs. VO2max (R = 0.545; p < 0.001); MAXTT vs. TTVT2 (R=0.560; p < 0.01) and between TTVT2 vs. VO2VT2 (R=0.610; p < 0.001). The results allowed us to infer that the attainment of maximum aerobic power together with increased of VO2VT2 are predictors of a higher aerobic capacity in soccer players. The best predictive parameter of exercise tolerance in all positions was the relationship VO2VT2 vs. VO2max.

Dissertação de Mestrado em Segurança AlimentarListeria monocytogenes é o agente causal da listeriose, infeção rara, mas severa, cuja taxa de fatalidade pode atingir 20% na população humana. A listeriose é quase exclusivamente transmitida pelo consumo de alimentos contaminados. Os alimentos prontos a consumir são muito associados a L. monocytogenes, pois são conservados por longos períodos em refrigeração, durante os quais L. monocytogenes pode desenvolver-se devido ao seu caráter psicrotrófico. A legislação europeia estabeleceu limites para presença e quantificação de L. monocytogenes em alimentos, consoante a etapa da cadeia alimentar em que estes se encontram: no produtor, o alimento deverá demonstrar ausência de L. monocytogenes em 25g e na distribuição comercial poderá conter um máximo de 102 ufc/g de alimento. Usando um challenge test, o presente trabalho visou avaliar a evolução do desenvolvimento da estirpe L. monocytogenes CECT 4031 inoculada artificialmente em salada com frango pronta a consumir, durante a vida útil refrigerada. Esta estirpe foi selecionada por pertencer ao serótipo 1/2a, que é aquele que mais comummente é isolado dos alimentos e que é associado a muitos casos de doença humana. Antes da inoculação, L. monocytogenes foi exposta a um choque com posterior adaptação ao frio (5°C), com o objetivo de simular uma possível adaptação ao ambiente industrial, que é geralmente refrigerado para a produção de saladas prontas para consumir. Utilizou-se uma suspensão com 5 log ufc/ml de L. monocytogenes CECT 4031, para a inoculação das saladas que foram mantidas a 5ºC durante os 7 dias de vida útil. As saladas foram analisadas nos dias 0, 4 e 7 e realizaram-se três réplicas experimentais. Os resultados mostraram que L. monocytogenes variou de 6,1 ± 0,6 log ufc/g a 6,4 ± 0,8 log ufc/g do dia 4 ao dia 7, respetivamente. Os resultados foram analisados e comparados com curvas de crescimento de referência e foram explorados potenciais cenários, considerando a vida útil refrigerada do alimento em estudo. A partir dos resultados estimou-se a quantidade de L. monocytogenes que poderia hipoteticamente estar presente na fase de produção, de forma que o limite legal de 100 ufc/g de alimento no final da vida útil não fosse ultrapassado.
ABSTRACT - Listeria monocytogenes in ready-to-eat chicken salad: challenge testing for shelf life assessment - Listeria monocytogenes is the causal agent of listeriosis, a rare but severe life-threatening human illness, with a fatality rate of about 20%. Listeriosis is almost exclusively transmitted by food consumption. L. monocytogenes is especially related to ready-to-eat foods, because of the long refrigerated shelf life, during which L. monocytogenes may thrive and develop, due to its psychrotrophic character. European legislation establishes two different limits for L. monocytogenes in ready-to-eat foods, according to the food chain stakeholder: in the producer absence of L. monocytogenes in 25g of food is required, whereas while the foods are placed on the market up to 100 ufc/g may be present. Using a challenge test, this work aimed to assess L. monocytogenes CECT 4031 growth when artificially inoculated in a ready-to-eat chicken salad, during its refrigerated shelf life. This L. monocytogenes strain was selected because it belongs to serotype 1/2a, the one that is most commonly isolated from foods and associated with many cases of human illness. Before inoculation, L. monocytogenes was previously exposed to a cold stress and adaptation to refrigerated temperature (5ºC), in order to recreate a possible adaptation to the industrial environment, which is usually kept under refrigeration for the preparation of ready-to-eat salads. A 5 log cfu/ml suspension of L. monocytogenes CECT 4031 was used to inoculate the salads that were kept at 5ºC during its 7 days shelf life. Salads were analyzed at day 0, 4 and 7 and three experimental replicates were performed. L. monocytogenes enumeration ranged from 6.1±0.6 log cfu/g to 6.4±0.8 log cfu/g from day 4 to day 7, respectively. Results were analyzed and compared with reference growth curves and potential scenarios were explored, considering the refrigerated shelf life of chicken salads. The hypothetical maximum concentration of L. monocytogenes that could be present at the production stage was estimated, in order to comply with the mandatory limit of 100 cfu/g at the end of shelf life.

El objetivo de la tesis es realizar aportaciones en el campo de las estrategias de test basadas en la vigilancia del consumo quiescente de los circuitos integrados CMOS y de los sensores utilizados para dicho fin (test de corriente o test iddq). Para ello se analiza en primer lugar el estado del arte en el diseño de sensores para el test IDDQ y se extraen criterios para la evaluacion de la calidad de dichos sensores. En la tesis se propone un nuevo tipo de sensor integrado (proportional built-in current sensor) que utiliza como elemento transductor un transistor bipolar compatible con la tecnologia CMOS. Se caracteriza tambien su comportamiento estetico y dinamico y se realizan pruebas con circuitos experimentales para validar los analisis realizados.En la tesis se proponen dos metodos originales para el test IDDQ mediante sensores externos al circuito que se este verificando (cut): el primero se basa en la desconexion de la alimentacion del cut y en la observacion del comportamiento de sus salidas. El segundo metodo se basa en el analisis de la evolucion de la tension en el nodo de alimentacion de un CUT cuando se le aplica un conjunto de vectores de test estando el circuito alimentado por un condensador. Ambos metodos propuestos requieren un interruptor para la alimentacion del CUT con unas caracteristicas especiales. Por ello, se ha diseñado un nuevo tipo de interruptor que cumple con las especificaciones de baja resistencia en estado de conduccion y baja inyeccion de carga en el paso del estado de no conduccion al de conduccion. Finalmente, los metodos propuestos se han validado experimentalmente al ser implementados en una maquina de test convencional verificandose su efectividad en la deteccion de los defectos de multiples circuitos integrados.

obesity affects rightly functional capacity diminishing the cardiovascular system efficiency and oxygen uptake (VO2). Field tests, such as, Incremental Shuttle Walking Test (ISWT) and Six Minute Walk Test (6MWT) has been employed as alternative of Cardiopulmonary Exercise Test (CPX), to functional assessing for conditions which transport of oxygen to peripheral is diminished. Nevertheless, the knowing about metabolic variables response in real time and it comparing among different maximal and submaximal tests in obese is absent. Aim: to compare cardiopulmonary, metabolic response during CPX, ISWT and 6MWT and to analyse it influence of adiposity markers in obese. Material e Method: crosssectional, prospective study. Obese included if: (BMI>30Kg/m2; FVC>80%), were assessed as clinical, anthropometric (BMI, body adiposity index-BAI, waist-WC, hip- HC and neck-NC circumferences) and spirometry (forced vital capacity-FVC, Forced expiratory volume-1?second-FEV1, maximal voluntary ventilation-MVV) variables. Obese performed the sequence of tests: CPX, ISWT and 6MWT. Throughout tests was assessed breath-by-breath by telemetry system (Cortex-Biophysik-Metamax3B) variables; oxygen uptake on peak of activity (VO2peak); carbon dioxide production (VCO2); Volume Expiratory (VE); ventilatory equivalents for VO2 (VE/VO2) and CO2 (VE/VCO2); respiratory exchange rate (RER) and perceived effort-Borg6-20). Results: 15 obese (10women) 39.4+10.1years, normal spirometry (%CVF=93.7+9.7) finished all test. They have BMI (43.5+6.6kg/m2) and different as %adiposity (BAI=50.0+10.5% and 48.8+16.9% respectively women and men). Difference of VO2ml/kg/min and %VO2 were finding between CPX (18.6+4.0) and 6MWT (13.2+2.5) but not between ISWT (15.4+2.9). Agreement was found for ISWT and CPX on VO2Peak (3.2ml/kg/min; 95%; IC-3.0 9.4) and %VO2 (16.4%). VCO2(l/min) confirms similarity in production for CPX (2.3+1.0) and ISWT (1.7+0.7) and difference for 6MWT (1.4+0.6). WC explains more the response of CPX and ISWT than other adiposity markers. Adiposity diminishes 3.2% duration of CPX. Conclusion: ISWT promotes similar metabolic and cardiovascular response than CPX in obese. It suggesting that ISWT could be useful and reliable to assess oxygen uptake and functional capacity in obese
a obesidade afeta diretamente a capacidade funcional diminuindo a efici?ncia do sistema cardiovascular e o consumo de oxig?nio (VO2). Testes de campo, tais como, Incremental Shuttle Walking Test (ISWT) e Teste de Caminhada de 6 minutos (TC6M) tem sido empregados como alternativa ao Teste de Esfor?o Cardiopulmonar (TECP), para avalia??o funcional de patologias que levam a diminui??o da transfer?ncia de oxig?nio ? periferia, entretanto, pouco ? conhecido da respostas fisiol?gicas de vari?veis metab?licas e ventilat?rias em obesos durante teste incremental de exerc?cio. Objetivo: analisar e comparar as respostas cardiopulmonares, metab?licas (VO2pico-consumo de oxig?nio-pico e VCO2-produ??o de di?xido de carbono) e de esfor?o percebido nos testes subm?ximos de esfor?o (ISWT e TC6M) com o TECP. Materiais e M?todo: estudo transversal, prospectivo, onde foi avaliada a concord?ncia de dois diferentes testes de campo (TC6M e ISWT) com o TECP. Crit?rios de Inclus?o (IMC > 30Kg/m2; CVF > 80%). Os participantes realizaram avalia??o cl?nica, antropom?trica (IMC, IAC-?ndice de adiposidade corporal, RCQ-rela??o cintura-quadril, CQ-circunfer?ncia quadril, CC-circunfer?ncia cintura, CP-circunfer?ncia pesco?o) e espirom?trica (CVF-capacidade vital for?ada, VEF1-volume expirat?rio for?ado no 1? segundo, VVM-ventila??o volunt?ria m?xima). Obesos realizaram em momentos distintos a sequ?ncia de testes (TECP, TC6M e ISWT). Medidas ventilat?rias (VE-ventila??o por minuto, VE/VO2-equivalente ventilat?rio de oxig?nio, VE/VCO2-equivalente ventilat?rio de di?xido de carbono, RER-raz?o de troca gasosa) e metab?licas (VO2 e VCO2) dos gases expirados (breath-by-breath) com sistema de telemetria (Cortex-Biophysik-Metamax3B), al?m das vari?veis de percep??o de esfor?o (fadiga e dispneia-Borg6-20) foram tomadas. Resultados: os participantes eram adultos jovens (39.4+10.1 anos), com altos percentuais de adiposidade corporal (IAC=50.0+10.5%-mulheres; IAC=48.8+16.9%- homens) e IMC=43.5+6.6. Observou-se que IMC e CC justificaram isoladamente 56% e 48% da vari?ncia da dura??o do TECP. Diferen?as de VO2ml/kg/min e %VO2 nos obesos foram encontradas apenas entre TECP e TC6M (%VO2 p=0.008 em mulheres e p=0.01 nos homens), sendo os valores de VO2PICO de 18.6+4.0ml/kg/min no TECP; 15.4+2.9 no ISWT e 13.2+2.5 no TC6M. O Bland-Altman evidenciou concord?ncia entre TECP e o ISWT no VO2PICO (3.2ml/kg/min; 95%; IC -3.0 9.4) e no %VO2 (16.4%; 95%; -23.6 56.4). A an?lise da produ??o de CO2(l/min) xiv confirmou uma maior produ??o ao final do TECP (2.3+1.0), seguido do ISWT (1.7+0.7) e TC6M (1.4+0.6), por?m com diferen?as apenas entre o TECP e TC6M (p<0.01). Conclus?o: apesar de considerado um teste de esfor?o subm?ximo, o ISWT promove respostas metab?licas e cardiovasculares semelhantes ao TECP na popula??o obesa, sugerindo que o ISWT pode ser uma boa op??o para avaliar a capacidade funcional de obesos

Objetivo. Estudar o consumo alimentar de mulheres obesas na fila de espera para cirurgia bariátrica a partir de inquéritos do consumo pregresso das últimas 24 horas e dos últimos 30 dias, seguindo-se protocolos correntes de validação e reprodutibilidade de inquéritos de frequência alimentar e de avaliação do padrão dietético. Métodos: As participantes do estudo foram mulheres recrutadas na fila de espera para a cirurgia bariátrica, em três distintas fases. Na primeira, foram analisados os registros de consumo alimentar de 24 horas (Rg24h) de 100 mulheres para gerar um questionário de frequência alimentar (QFA) com 97 itens. Na segunda fase o QFA foi aplicado simultaneamente ao Rg24h de 3 dias não consecutivos, em 81 mulheres, seguindo procedimentos de validação (QFA1). Na terceira fase o QFA foi novamente aplicado, em 74 mulheres, seguindo procedimentos de reprodutibilidade (QFA2). Uma segunda análise foi realizada para determinar comparativamente o padrão alimentar obtido no QFA1 e QFA2 por meio de análise fatorial de componentes principais. Resultados: A concordância dos dados do QFA1 e o Rg24, avaliada pelo coeficiente Kappa, foram nulos com valores entre -0,0633 e 0,0505 para energia e nutrientes avaliados. Os padrões alimentares expressos pelo QFA1 não foram refletidos no QFA2. Conclusão: Assim, conclui-se que as abordagens convencionais de avaliação do consumo alimentar mostraram resultados inconsistentes nessa população. Outras abordagens ou critérios mais rigorosos para aplicação dessas mesmas abordagens podem ser necessários para mitigar as inconsistências aqui identificadas.
This study aimed to investigate the food intake of obese women in the waiting line for bariatric surgery using 24-hour and 30-day recalls that comply with the current validation and reproducibility protocols for such questionnaires and assessment of dietary patterns. Methodology: The study had three distinct phases. The first phase analyzed the 24-hour recall (24HR) of 100 women, which generated a food frequency questionnaire (FFQ) with 97 items. In the second phase, the FFQ and 24HR were administered simultaneously on three nonconsecutive days to 81 women according to the validation procedures (FFQ1). In the third phase, the FFQ was again administered to 74 women according to the reproducibility procedures (FFQ2). A second analysis compared the food patterns extracted from FFQ1 and FFQ2 by principal components factor analysis. Results: According to the Kappa coefficient, the agreement between FFQ1 and 24HR was null, with values ranging from -0.0633 and 0.0505 for energy and the study nutrients. The food patterns expressed by FFQ1 were not reflected by FFQ2. Conclusion: In conclusion, the conventional approaches to assess food intake produced inconsistent results in this population. Other approaches or more rigorous criteria for using these same approaches may be necessary to mitigate the inconsistencies found.

Full textAbstract:
Branding in the age of social media is thriving as companies continue to pour resources into digital campaigns in the hope of engaging their customers. The onset of the COVID- 19 pandemic boosted the importance of digital communication channels as physical distancing and lockdown measures disrupted business-as-usual and limited in-person interactions between firms and their customers. By implication, the global crisis pressed companies to deliver brand messages via online content to sustain or build customer relationships. This research focuses first on the branded content of corporate communications during the pandemic, focusing specifically on whether firms used the opportunity to showcase shared personal values. Second, we examine whether using value words in social media messages impacts customer engagement with these messages.
To address these related questions, we collected Twitter data from Fortune 500 firms posted between January 2020 until the end of August 2020, attending to 56,770 firm- initiated tweets (we excluded firm responses to customer messages). The first study examines the personal values expressed in the messages using the Personal Values Dictionary, based on Shalom Schwartz’s original ten-value typology. We argue that the unprompted expression of values in a text is a behavioural indicator of personal value priorities. The findings compare firms’ shifting value priorities over time and association with key events, namely the global pandemic declaration (March 11, 2020) and ensuing lockdowns and George Floyd’s murder (May 25, 2020), and BLM protests. We find that, indeed, companies did shift their value priorities. The second study assesses consumer response to the values companies put forth in their tweets, focusing on social media indicators of consumer engagement (CE), including the number of likes, retweets, replies, and CE correlation with the values promoted in the tweets. We observe a pre- post-crisis shift in CE with value-laden messages. Our findings provide managerial insights that can guide marketers to manage their social media content more efficiently and better align their marketing and branding efforts with customers' values in times of crisis.

Different types of tests enable the standardized assessment of functional capacity and exercise; however, the intensity of physiological demands induced by these tests hasn´t been elucidated on children. The objective of this study was to investigate the physiological responses induced by the modified shuttle walk test (MSWT), six-minute walk test (6MWT) and activity of daily living Glittre test for the pediatric population in healthy children and adolescents and compare the intensity of the physiological demands induced by these tests. Methods: children and adolescents with normal pulmonary function performed the TGlittre-P, 6MWT and MSWT with direct analysis of expired gases (K4b2, Cosmed®, Italy). The tests were performed in three different days, within a maximum interval of 15 days between the first and third day of evaluation. Results: oxygen uptake (VO2) during the MSWT was significantly higher than the VO2 reached at the TGlittre-P and the 6MWT, between the TGlittre-P and 6MWT there were no differences, and this behavior has been observed in most physiological variables. When performing the MSWT, most children (67%) reached the maximum effort. The time taken on TGlittre-P was significantly associated with the covered distance 6MWT (CD6MWT) and MSWT (CDMSWT) (r = -0.51, r = -0.53 respectively). The CD6MWT and CDMSWT showed a correlation coefficient moderately high (r = 0.67). Between the second and the third round of TGlittre-P and from the first minute of the 6MWT the metabolism reached steady state. Conclusion: The TGlittre-P and the 6MWT are submaximal tests that showed similar physiological responses and require less metabolic, respiratory and cardiovascular overload, compared to MSWT.
Diversas modalidades de testes viabilizam a avaliação padronizada da capacidade funcional e de exercício, contudo a magnitude das demandas fisiológicas induzidas por estes testes ainda não foi elucidada na população pediátrica. O objetivo deste estudo foi investigar as respostas fisiológicas induzidas pelo modified shuttle walk test (MSWT), teste de caminhada de seis minutos (TC6) e teste de atividade de vida diária Glittre (TGlittre-P) em crianças e adolescentes saudáveis, bem como comparar a magnitude das demandas fisiológicas induzidas pelos testes. Métodos: crianças e adolescentes com prova de função pulmonar normal realizaram o TGlittre-P, TC6 e MSWT com análise direta dos gases expirados (K4b2, Cosmed®, Itália). Os testes foram realizados em três dias distintos, com intervalo máximo de 15 dias entre o primeiro e terceiro dia de avaliação. Resultados: o consumo de oxigênio (VO2) no decorrer do MSWT foi significativamente superior ao VO2 obtido no TGlittre-P e no TC6. Não houve diferença entre e VO2 no TGlittre-P e TC6, assim como ocorreu na maioria das variáveis fisiológicas. Ao realizarem o MSWT, a maioria das crianças (67%) atingiram o esforço máximo. O tempo despendido no TGlittre-P se relacionou significativamente com a distância percorrida no TC6 (DPTC6) e no MSWT (DPMSWT) (r = -0,51; r = -0,53 respectivamente). A DPTC6 e DPMSWT relacionaram-se com grandeza moderadamente alta (r = 0,67,). Entre a segunda e a terceira volta do TGlittre-P, e a partir do primeiro minuto do TC6, o metabolismo atingiu o estado estável. Conclusão: o TGlittre-P e o TC6 são testes de campo submáximos que apresentaram respostas fisiológicas similares e requerem uma menor sobrecarga metabólica, ventilatória e cardiovascular, em comparação ao MSWT.

O Brasil possui uma vasta diversidade de fontes energéticas. De grandes hidrelétricas, as quais são sua fonte principal, até os mais recentes parques eólicos e fotovoltáicos. No entanto, a despeito desta variedade de recursos energéticos há uma verdade negativa: a maioria das habitações no país usa chuveiros elétricos. Esses dispositivos são responsáveis por 43% do pico de demanda de energia elétrica doméstico Brasileiro. Esse pico de demanda de energia causa problemas não só à companhia geradora de energia, a qual tem que reservar pelo menos quatro giga watts para fornecê-lo, mas também para à empresa de distribuição de energia elétrica devido à sobrecarga e/ou superdimensionamento de cabos e danos aos transformadores. Com o objetivo de transferir o uso de energia elétrica para aquecimento de água para o amanhecer, um novo Sistema de Aquecimento Solar de Água Doméstico foi simulado e testado. O objetivo deste sistema é planificar o perfil de consumo de energia elétrica de urna casa. Este sistema usa dois tanques e dados de previsão do tempo para prever a energia solar absorvida pelo coletor para o próximo dia, a fim de evitar possíveis condições climáticas desfavoráveis. A análise computacional foi realizada utilizando o software TRNSYS. O sistema apresentado foi capaz de diminuir o pico da demanda de energia elétrica. As simulações forneceram dados esperados e provaram que o sistema pode ser usado em muitas regiões brasileiras, um dando o pico de demanda de energia de uma habitação. No entanto, à medida que os erros de previsão simulados aumentaram, o sistema não conseguiu fornecer água quente ao usuário com mais frequência. Mais pesquisas são necessárias para rastrear uma tendência para justificar um ponto de parada para o aumento da precisão da previsão do tempo. Além disso, para validar a simulação, uma bancada de testes foi projetada e construída. A comparação de dados simulados e experimentais mostrou que os tanques utilizados na plataforma experimental possuem perdas muito altas. Portanto, a plataforma experimental não conseguiu fornecer os resultados esperados para o experimento a longo prazo. A simulação, por outro lado, pôde ser validada através de testes específicos na bancada experimental. Logo, os resultados simulados representam o verdadeiro comportamento do sistema.
Abstract : Brazil uses many renewable energy sources. From hydropower, which is its main source, to the recent photovoltaic and wind farms. However, beneath the Brazilian energy resources is a negative truth: most dwellings in the country uses electric shower heaters. These devices are responsible for 43% of the Brazilian domestic electric energy demand peak. This peak causes problems not only to the electric energy system, which has to reserve at least four gigawatts to supply it, but also to electrical energy distribution company due to cable overload and/or oversizing and transformers damage. In order to shift the electric energy use to dawn a novel Solar Domestic Water Heating system was simulated and tested. The objective of this system is to flatten the electrical energy consumption profile of a house. This system uses two tanks and weather forecast data to predict the solar energy absorbed by the collector for the next day in order to prevent for possible unfavorable climatic conditions. Computational analysis was carried using the TRNSYS software. Also a Test bed was built in order to compare results. The presented system design was able to shift and shrink the energy demand peak for hot water of a household. Simulations delivered expected data and proved the system may be used in many Brazilian regions shifting the energy demand peak of a dwelling. However, as the simulated forecast errors increased, the system failed to deliver hot water to the user more often. More research must be done in order to trace down a tendency that could justify a stopping point on increasing the accuracy of the weather forecast. In addition, to validate the simulation the author designed and built a test-bed. Comparing simulated and experimental data showed that the tanks used on the experimental rig were far from ideal. Therefore, the experimental rig could not deliver expected results for the long-term experiment. The simulation, on the other hand, could be validated and its results represent the true system behavior.

Previous issue date: 2011-07-13This work interrogates the contemporary processes of training, educational or not, increasingly varied and diverse and that develop in a wide range of social levels, from traditional institutions like family and school practices by focusing on individual and collective consumption goods , or other technology. Shows that the current society is inherently a form of material life, centered on the production is the production of objects with values of exchange, goods, and inseparable from the alienation and reification. This society has been thoroughly studied and understood by Marx (1818-1883) and Lukacs as discussed below. It also demonstrates that in its most advanced society that leads to extreme forms of alienation and fetishization of social life studied, conceived by Guy Debord (1931-1994), and work to create the concept of society of the spectacle, in his quest to understand the current form of alienation. Here we emphasize the importance of the commodity technology as a mediation between the individual and social life, particularly as a means of communication and information. From this idea of society and its characteristics as the expansion of the image or the products and vehicles of cultural industry, reflects on the mechanisms of formation to develop this historical and social formation. Highlights the siege to formal education and commercial institutions, traditional socialization and the importance of children as consumers semiformal, marketing and economicização pedagogical practices and teaching institutions.
Este trabalho interroga os processos de formação contemporâneos, escolares ou não, cada vez mais múltiplos e variados e que se desenvolvem em ampla gama de instância sociais, desde as instituições tradicionais como a família e a escola até as práticas coletivas e individuais centradas no consumo de mercadorias, tecnológicas ou outras. Mostra que à sociedade atual é inerente uma forma de vida material, centrada na produção de objetos com valores de troca, mercadorias, e inseparável da alienação e da reificação. Essa sociedade foi rigorosamente estudada e compreendida por Marx (1818-1883) e Lukács como veremos abaixo. Demonstra ainda que em seus estágios mais avançados essa sociedade leva ao extremo as formas de alienação e fetichização da vida social estudadas, pensadas por Guy Debord (1931-1994), ao criar e trabalhar o conceito de sociedade do espetáculo, em sua busca de compreender a forma atual de alienação. Ressalta a importância da mercadoria tecnológica como mediação entre o indivíduo e a vida social, em especial como meio de comunicação e informação. A partir dessa ideia de sociedade e suas especificidades como a expansão da imagem ou dos produtos e veículos da indústria cultural, reflete sobre os mecanismos de formação que desenvolvem-se nessa formação histórico-social. Destaca o cerco mercantil à educação formal e às instituições, tradicionais de socialização assim como a importância semiformativa do consumo infantil, da comercialização e economicização das práticas pedagógicas e das instituições de ensino.

Full textAbstract:
A tendência à implantação e certificação de Sistemas de Gestão da Qualidade (SGQ) tem sido estudada pelo mundo, pois há diversos autores que citam como uma das maiores influências para a implantação desse sistema a melhora do relacionamento com o cliente. Porém, apesar da crença na relação entre a qualidade, satisfação do cliente e retorno econômico, é preciso uma melhor compreensão nesta área. Este trabalho tem por objetivo avaliar a relação entre a implantação de SGQ e a satisfação dos clientes de empreendimentos imobiliários novos na cidade de Curitiba. Para a obtenção de dados, a fim de sustentar este trabalho, realizou-se um estudo preliminar e um trabalho de levantamento quantitativo de dados. A primeira etapa buscou informações relevantes para a construção e a validação do questionário utilizado na segunda parte, a qual se destinou à captação da percepção do cliente final. Foram obtidos 386 questionários respondidos no período de março a novembro de 2013. Por meio de Análises Descritivas dos dados, verifica-se que amostra demonstra ser fiel ao universo da pesquisa, sem haver discrepâncias significativas. Para a realização da análise da amostra, considerou-se a abordagem definida pelos autores Hair et al. (2010), em que um modelo de satisfação do cliente só é plenamente compreendido quando se estuda: a variável, os construtos e os relacionamentos entre duas ou mais variáveis. Portanto, realizaram-se diversas Análises Descritivas, bem como os testes estatísticos Qui-Quadrado e Análise Discriminante, a fim de estudar as variáveis componentes da satisfação. Em seguida os constructos, os quais foram obtidos por meio da Análise Fatorial. Foram estudados por fim, a relação entre as variáveis através da Regressão Linear Múltipla dos dados. Como resultado desta pesquisa, percebeu-se que não é possível basear a conclusão final do estudo somente pela média da satisfação global, pois esta pode encobrir outros resultados. Além disso, verificou-se que as variáveis padrão do imóvel e tipo de gestão (com ou sem SGQ) podem influenciar na satisfação do cliente. Como exemplo, os participantes de empreendimentos construídos sem SGQ mostraram-se mais satisfeitos do que os daqueles construídos com SGQ e o grupo dos participantes de empreendimentos com padrão baixo, os mais insatisfeitos dentre todos os padrões. Por meio da Análise Fatorial, foram encontrados 4 fatores: a) comunicação com a empresa, b) produto, c) localização, d) projeto, bem como um fator geral, a satisfação global. Em relação à insatisfação, esta é evidente nos fatores que apresentaram maior importância, comunicação com a empresa e produto. Acredita-se que embora este estudo seja válido apenas para Curitiba, o desenvolvimento e a estrutura deste modelo oferecem uma referência consistente para a avaliação da satisfação do cliente na construção civil em outros contextos.The tendency to implementation and certification of quality management systems have been studied around the world, many authors cite as one of the biggest influences the improve the customer relationship. Despite the belief in the link between quality, customer satisfaction and economic returns, we need to learn more about this area. The propose of this study is to evaluate customer satisfaction of new buildings in the city of Curitiba. To get the data, we conducted a preliminary study and a quantitative survey. The first step searched for information to the construction and validation of the questionnaire used in the second part, which was destined to final customer. We obtained 386 questionnaires during March to November 2013. And through descriptive data analysis, we found that sample is true to the universe studied, because there are not significant differences. To perform the analysis of the sample, we considered the approach defined by the authors Hair et al. (2010), where a model of customer satisfaction is completely understood only when we studied: the variable, constructs, and relationships between two or more variables. Therefore, we performed several descriptive analyzes and the chi-square test in order to study the variable components of satisfaction. Next the constructs, which were obtained from through factor analysis. And last, we check the relationship between variables through multiple linear regressions of the data. As a result of this work, we noticed that it is not possible to rely only on the average overall satisfaction, because it may mask other results. In addition, we found that the variables: the default of the building and type of management (with or without TQM), can influence customer satisfaction. For example, participants of buildings built without TQM are more satisfied than those built with TQM, and the group of participants of buildings of low default is the most unhappy of all the defaults. Through factor analysis, we found four factors, communication with the company, product, location, design, as well as a general factor, overall satisfaction. The dissatisfaction is evident in the two most important factors: communication with the company and product. It is believed that, although our study is valid only for Curitiba, the development and structure of this model provide a great reference for the evaluation of customer satisfaction in other settings of the construction industry.

Previous issue date: 2007-12-03The relation between metabolic demand and maximal oxygen consumption during exercise have been investigated in different areas of knowledge. In the health field, the determination of maximal oxygen consumption (VO2max) is considered a method to classify the level of physical fitness or the risk of cardiocirculatory diseases. The accuracy to obtain data provides a better evaluation of functional responses and allows a reduction in the error margin at the moment of risk classification, as well as, at the moment of determination of aerobic exercise work load. In Brasil, the use of respirometry associated to ergometric test became an opition in the cardiorespiratory evaluation. This equipment allows predictions concerning the oxyredutase process, making it possible to identify physiological responses to physical effort as the respiratory threshold. This thesis focused in the development of mathematical models developed by multiple regression validated by the stepwise method, aiming to predict the VO2max based on respiratory responses to physical effort. The sample was composed of a ramdom sample of 181 healthy individuals, men and women, that were randomized to two groups: regression group and cross validation group (GV). The voluntiars were submitted to a incremental treadmill test; objetiving to determinate of the second respiratory threshold (LVII) and the Peak VO2max. Using the m?todo forward addition method 11 models of VO2max prediction in trendmill were developded. No significative differences were found between the VO2max meansured and the predicted by models when they were compared using ANOVA One-Way and the Post Hoc test of Turkey. We concluded that the developed mathematical models allow a prediction of the VO2max of healthy young individuals based on the LVII

An integrated circuit (IC) in test mode has a higher energy consumption compared to the normal operating mode, due to the increased number of transitions in the nodes of the resulting circuit applying test patterns used to stimulate the CI during the test run resulting in high power dissipation which can damage the IC, resulting in higher costs for manufacturers. In this work we propose a genetic algorithm to optimize sequences of test patterns aiming at low energy consumption during the test run, maintaining an adequate fault coverage. It is also proposed using the Berlekamp-Massey algorithm to synthesize an integrated test patterns with low hardware sobreárea generator capable of generating sequences optimized based on Shift Register with Linear Feedback. The optimization of the sequences is done by reducing the number of transitions at nodes whose evaluation is done by a computer program developed in this study in C ++. Finally, simulations were performed with the genetic algorithm to check the behavior to optimize the number of transitions, the fault coverage and hardware sobreárea.
Um circuito integrado (CI) em modo de teste apresenta um maior consumo energético comparado ao modo de operação normal, devido ao aumento do número de transições nos nós do circuito decorrentes da aplicação de padrões de teste utilizados para estimular o CI durante a execução do teste resultando em uma alta dissipação de potência que pode danificar o CI, acarretando em maiores custos para as fabricantes. Assim, neste trabalho é proposto um algoritmo genético para otimização de sequências de padrões de teste visando o baixo consumo energético, durante a execução do teste, mantendo uma adequada cobertura de falhas. É proposto também o uso do algoritmo de Berlekamp-Massey para sintetizar um gerador integrado de padrões de teste com baixa sobreárea de hardware capaz de gerar as sequências otimizadas baseado em Registrador de Deslocamento com Realimentação Linear. A otimização das sequências é feita através da redução do número de transições nos nós cuja avaliação é feita por um programa de computador desenvolvido nesta pesquisa em C++. Por fim, simulações foram realizadas com o algoritmo genético para verificar o comportamento em relação a otimização do número de transições, da cobertura de falhas e da sobreárea de hardware.

Full textAbstract:
Purpose – The aim of this thesis is to explore the possibility of text mining social media, for consumer insights from an organizational perspective. Design/methodology/approach – An exploratory, single case embedded case study with inductive approach and partially mixed, concurrent, dominant status mixed method research design. The case study contains three different studies to try to triangulate the research findings and support research objective of using social media for consumer insights for new products, new ideas and helping research and development process of any organization. Findings – Text mining is a useful, novel, flexible and an unobtrusive method to harness the hidden information in social media. By text-mining social media, an organization can find consumer insights from a large data set and this initiative requires an understanding of social media and its building blocks. In addition, a consumer focused product development approach not only drives social media mining but also enriched by using consumer insights from social media. Research limitations/implications – Text mining is a relatively new subject and focus on developing better analytical tool kits would promote the use of this novel method. The researchers in the field of consumer driven new product development can use social media as additional evidence in their research. Practical implications – The consumer insights gained from the text mining of social media within a workable ethical policy are positive implications for any organization. Unlike conventional marketing research methods text mining is social media is cost and time effective. Originality/value –This thesis attempts to use innovatively text-mining tools, which appear, in the field of computer sciences to mine social media for gaining better understanding of consumers thereby enriching the field of marketing research, a cross-industry effort. The ability of consumers to spread the electronic word of mouth (eWOM) using social media is no secret and organizations should now consider social media as a source to supplement if not replace the insights captured using conventional marketing research methods.

Full textAbstract:
Purpose: The Internet has provided an unprecedented opportunity for psychotropic medication consumers, a traditionally silenced group in clinical trial research, to have voice by contributing to the construction of drug knowledge in an immediate, direct manner. Currently, there are no systematic appraisals of the potential of online consumer drug reviews to contribute to drug knowledge. The purpose of this research was to explore the content of drug information on various websites representing themselves as consumer- and expert-constructed, and as a practical consideration, to examine how each source may help and hinder treatment decision-making. Methodology: A mixed-methods research strategy utilizing a grounded theory approach was used to analyze drug information on 5 exemplar websites (3 consumer- and 2 expert-constructed) for 2 popularly prescribed psychotropic drugs (escitalopram and quetiapine). A stratified simple random sample was used to select 1,080 consumer reviews from the websites (N=7,114) through February 2009. Text was coded using QDA Miner 3.2 software by Provalis Research. A combination of frequency tables, descriptive excerpts from text, and chi-square tests for association were used throughout analyses. Findings: The most frequently mentioned effects by consumers taking either drug were related to psychological/behavioral symptoms and sleep. Consumers reported many of the same effects as found on expert health sites, but provided more descriptive language and situational examples. Expert labels of less serious on certain effects were not congruent with the sometimes tremendous burden described by consumers. Consumers mentioned more than double the themes mentioned in expert text, and demonstrated a diversity and range of discourses around those themes. Conclusions: Drug effects from each source were complete relative to the information provided in the other, but each also offered distinct advantages. Expert health sites provided concise summaries of medications’ effects, while consumer reviews had the added advantage of concrete descriptions and greater context. In short, consumer reviews better prepared potential consumers for what it’s like to take psychotropic drugs. Both sources of information benefit clinicians and consumers in making informed treatment-related decisions. Social work practitioners are encouraged to thoughtfully utilize online consumer drug reviews as a legitimate additional source for assisting clients in learning about treatment options.

Il primo studio ha verificato l'affidabilità del software Polimedicus e gli effetti indotti d'allenamento arobico all’intensità del FatMax. 16 soggetti sovrappeso, di circa 40-55anni, sono stati arruolati e sottoposti a un test incrementale fino a raggiungere un RER di 0,95, e da quel momento il carico è stato aumentato di 1 km/ h ogni minuto fino a esaurimento. Successivamente, è stato verificato se i valori estrapolati dal programma erano quelli che si possono verificare durante a un test a carico costante di 1ora. I soggetti dopo 8 settimane di allenamento hanno fatto un altro test incrementale. Il dati hanno mostrato che Polimedicus non è molto affidabile, soprattutto l'HR.
Nel secondo studio è stato sviluppato un nuovo programma, Inca, ed i risultati sono stati confrontati con i dati ottenuti dal primo studio con Polimedicus. I risultati finali hanno mostrato che Inca è più affidabile.
Nel terzo studio, abbiamo voluto verificare l'esattezza del calcolo del FatMax con Inca e il test FATmaxwork. 25 soggetti in sovrappeso, tra 40-55 anni, sono stati arruolati e sottoposti al FATmaxwork test. Successivamente, è stato verificato se i valori estrapolati da INCA erano quelli che possono verificarsi durante un carico di prova costante di un'ora. L'analisi ha mostrato una precisione del calcolo della FatMax durante il carico di lavoro.
Conclusione: E’ emersa una certa difficoltà nel determinare questo parametro, sia per la variabilità inter-individuale che intra-individuale. In futuro bisognerà migliorare INCA per ottenere protocolli di allenamento ancora più validi.The most important treatment to prevent conditions such as being overweight and obesity, is regular exercise which increases daily energy expenditure and consumption of lipids. Numerous studies have described the relationship between exercise intensity and fat oxidation, the most recent in particular focused on FATmax. The first study verified the reliability of the software Polimedicus and the effects of aerobic training to FATmax. 16 overweight subjects were enrolled, about 40-55yrs old, and underwent incremental test until they reached an RER of 0.95, and from that moment the load increased of 1km/h every minute until exhaustion. Subsequently, it was checked if the values extrapolated from the program were those that may occur during a constant test of an hour. The subjects after 8 weeks did another incremental test. The final data has shown Polimedicus is not very reliable, especially the HR. In the second study new program was developed, Inca, and the results were compared to the data obtained from the first studies by Polimedicus. The final date have shows Inca is more reliable than Polimedicus. In the third study, we wanted to verify the accuracy of the calculation of the FATmax with Inca with the FATmaxwork test. 25 overweight subjects, between 40-55 yrs old, were enrolled and submitted to a FATmaxwork test. Subsequently, it was checked if the values extrapolated from INCA were those that may occur during a constant test load of an hour. The analysis showed accuracy of the calculation of FATmax during the workload. Conclusion: The difficulty of determining this parameter was highlighted, due both to the large inter-individual and intra-individual variability. In the future we need to improve INCA to allow us to obtain even more valid training protocols.
