Full textAbstract:
This study used a mixed qualitative-quantitative design to describe attachment in a sample of one-hundred fifty-four healthy community-living older adults. Life-span development and attachment theory combined to define the philosophical and theoretical orientation that guided the investigation. The idea of an "attachment structure" was conceptualized by the investigator to frame attachment--an approach that allowed attachment to involve multiple attachment objects from any or all of six different attachment object types (things, ideas, people, groups of people, animals, or places). The purpose of this study was to explore and describe the attachment structure as it presented in, and developed in later life. In phase one of the study, 154 older adults were administered a questionnaire designed to elicit descriptive information about the newly conceptualized "attachment structure". This information was used to guide theoretical sampling in the qualitative, second phase. In phase two, a grounded theory methodology was used to explore the developmental changes that occurred in attachment structures in later life. Sixteen subjects from phase one were selected, based on their responses to the quantitative phase, as those subjects most likely to advance the theory developing focus of this study. Analysis supported the attachment structure as a meaningful representation of socio-emotional development in later life. The existence of multiple attachment objects of multiple object types was supported by both quantitative and qualitative data. Significantly, in addition to close family and friends, subjects reported attachments to ideas like independence and freedom. A grounded process called "reconfiguring" was identified from qualitative analysis that described how older people make changes in their attachment structures to maintain a sense of security in the face of diminishing contact with attachment objects. Two pathways, the structural stimulation pathway and the reconfiguring pathway, describe the dynamics of the attachment structure. The reconfiguring pathway was identified as a developmental resource of aging--a process available to older people to address developmental challenges in aging that affect one's quality and quantity of interaction with attachment objects.

Full textAbstract:
Quantitative Trait Loci (QTL) mapping has been widely used to identify genetic loci attributable to the variation observed in complex traits. In recent years, gene expression phenotypes have emerged as a new type of quantitative trait for which QTL can be mapped. Locating sequence variation that has an effect on gene expression (eQTL) is thought to be a promising way to elucidate the genetic architecture of quantitative traits. This thesis explores a number of methodological aspects of eQTL mapping (also known as “genetical genomics”) and considers some practical strategies for applying this approach to livestock populations. One of the exciting prospects of genetical genomics is that the combination of expression studies with fine mapping of functional trait loci can guide the reconstruction of gene networks. The thesis begins with an analysis in which correlations between gene expression and meat quality traits in pigs are investigated in relation to a pork meat quality QTL previously identified. The influence on power due to factors including sample size and records of matched subjects is discussed. An efficient experimental design for two-colour microarrays is then put forward, and it is shown to be an effective use of microarrays for mapping additive eQTL in outbred crosses under simulation. However, designs optimised for detecting both additive and dominance eQTL are found to be less effective. Data collected from livestock populations usually have a pedigreed structure. Many family-based association mapping methods are rather computationally intensive, hence are time-consuming when analysing very large numbers of traits. The application of a novel family-based association method is demonstrated; it is shown to be fast, accurate and flexible for genetical genomics. Furthermore, the results show that multiple testing correction alone is not sufficient to control type I errors in genetical genomics and that careful data filtering is essential. While it is important to limit false positives, it is desirable not to miss many true signals. A multi-trait analysis based on grouping of functionally related genes is devised to detect some of the signals overlooked by a univariate analysis. Using an inbred rat dataset, 13 loci are identified with significant linkage to gene sets of various functions defined by Gene Ontology. Applying this method to livestock species is possible, but the current level of annotations is a limiting factor. Finally, the thesis concludes with some current opinions on the development of genetical genomics and its impact on livestock genetics research.

This study examined the relationship between mentored ministerial field educationâ s four components and student efficacy beliefs in 11 professional skills for students at several evangelical seminaries in the U.S. It also investigated whether students believed they had become competent practitioners of these skills or had received sufficient mentored field education in order for them to do so. A new self-efficacy survey was developed, and N=102 students from seven seminaries participated. Practice accounted for 7.9% of the variance in self-efficacy. Observation, instruction, and feedback were more weakly correlated with self-efficacy and not significant in the regression. On a scale from 0 (â I cannot do at allâ ) to 10 (â Highly certain I can doâ ), participantsâ self-efficacy in the skills ranged from 6.89 in counseling to 8.98 in â using and interpreting Scripture;â and there were indications that many participants had received a somewhat uneven field education. Only 23% of participants reported receiving sufficient practice and 19% sufficient feedback for them to become competent professionals. Future directions for research are suggested; and implications for both schools and churches are discussed from the perspective of instructional design, including incorporating studentsâ self-assessments into learner analysis and field education program evaluation.Ph.

The electronic engineering notebook is a pen-based computer tool designed to capture engineering notes and to assist in structuring them to facilitate subsequent information access. Experiments were conducted in which free-form and fixed-form note-taking interfaces were compared with respect to capturing and structuring notes from a design meeting. Suitability of domain-based and user-defined terminologies for semantic structuring was also tested. Results from the experiment confirmed that a free-form interface was easier to use for note-taking and structuring notes than were forms with fixed structure. However, difficulties with applying semantic categorizations were observed in both types of interface. The results indicated that terminology should be chosen appropriately to a task, and that experienced users have less problems with applying it. The experiment also demonstrated high diversity in note-taking styles, thus highlighting the need to accommodate individual preferences in electronic notebooks.

Full textAbstract:
Play therapy is a growing form of counseling that allows children to express themselves in the most natural way possible. Virginia Axline (1969) applied Roger's person centered theory and core conditions (empathic, genuineness and honesty, unconditional positive regard) to working with children in a therapeutic setting calling it Child Centered Play Therapy. Landreth (2002) further explored and developed child-centered play therapy concepts and techniques and emphasized the art of the relationship between the child and the counselor. Extant research on the effects of CCPT with children with different diagnoses, age groups, and settings is well-documented. However, there is a dearth of information concerning using CCPT in a school setting with children of ages 3-6 who were identified by the teachers as experiencing behavioral difficulties. Thus, the purpose of the study was to see if CCPT would help change behaviors with students that were identified as having behavior difficulties in the classroom. Three teachers observed and identified 12 students in grades pre-kinder 3, 4, and Kindergarten with behavioral difficulties in the classroom. Each of the 12 students was selected to receive an intervention using CCPT. For each of the 12 students, one parent/guardian completed the Child Behavior Check List forms each week, and the respective classroom teacher completed the Caregiver-Teacher Report form each week for the 12-week duration of the study. A single case research design was used, which included three weeks of baseline observation, followed by six weeks of CCPT with treatment twice per week, and three weeks of post baseline observation. Findings revealed that play therapy was a highly effective treatment for reducing negative behaviors in most students. Parents' ratings of behaviors indicated an 88.30% improvement in behaviors, and 50% of teachers' ratings indicated improved behavior change after receiving CCPT. In summary, 71% of all scores indicated change in behavior. Under further evaluation during the post baseline stage of the study, 90% of parents and 80% of teachers rated the student's behavior as improved. The results are indicative of CCPT being a very efficacious treatment intervention for students in grades pre-kinder 3, 4, and Kindergarten.

Lim, Yonghun. "Psychosocial inclusivity in design : a definition and dimensions." Thesis, Brunel University, 2018. http://bura.brunel.ac.uk/handle/2438/16683.
Full textAbstract:
Significant changes in demographics, including a growing ageing population and a larger number of people with disabilities, have made inclusive design an increasingly relevant notion in the design of products, services, and environments. However, there is considerable concern that the concept of inclusive design is rather limited in its current definition and applications and has not yet been thoroughly applied. This is possibly due to the conventional understanding and application of inclusive design, mainly rooted in and focused on physical aspects of inclusion, such as accessibility, usefulness, and usability. This limited focus has led various voices in design academia and industry to speak of the need for further consideration of the psychological and social aspects of inclusive design as the next step to facilitate inclusive design, and make impact. In this research, inclusivity on psychological and social levels, is referred to as "psychosocial inclusivity". The concept of psychosocial inclusivity, including a clear definition thereof and its application, is rather limited in the existing literature. Therefore, this PhD research aims to further explore this concept by establishing a clear definition and the dimensions thereof. In order to achieve this, an initial definition and dimensions of the psychosocial inclusivity in design are established through a critical review of existing literature from both social science and design perspectives. The initial definition and dimensions are then developed, refined, and evaluated through four empirical studies: the Delphi study (expert survey); field study I (ethnographic interviews with mobility scheme users); field study II (ethnographic interviews, creative workshop, and observation of older individuals); and an evaluation study (online survey of design academics and professionals). These studies have been designed based on a triangulation approach in order to enhance the reliability and validity of the outcomes. At the end of this research, the definition and dimensions for psychosocial inclusivity in design (Cognitive, Emotional, Social, and Value dimensions) are proposed. The outcomes of this research can enhance the understanding and knowledge of the concept of psychosocial inclusivity in design. Also, the definition and dimensions can be used by design academics and professionals or third parties to consider psychosocial aspects. The dimensions also can be developed as a complete set of framework or toolkit through further research.

Resumo: Atualmente, o uso da computação na medicina vem crescendo cada vez mais, e um dos temas mais discutidos é o prontuário clínico eletrônico. é consenso que a utilização de um prontuário eletrônico pode facilitar o trabalho do profissional de saúde e melhorar ainda mais a qualidade do cuidado em saúde, porém ainda existe muita discussão sobre como ele deve ser e quais ferramentas deve oferecer. Este trabalho propõe duas novas formas de visualização do prontuário. A primeira é um sumário com as informações mais relevantes do paciente. A segunda é a representação dos dados do paciente através de um diagrama, onde o profissional de saúde pode expressar o design rationale (DR) da consulta. A área de sumarização automática é um problema altamente complexo, e apesar de terem sido usados procedimentos muito simples, o experimento realizado mostrou que o processo foi suficiente para construir um sumário com o mínimo de informações necessárias para que o quadro clínico do paciente pudesse ser entendido. Alguns estudos apontam que a falta de informação sobre o processo de diagnóstico e sobre o planejamento do tratamento é uma das principais falhas de um sistema de prontuário eletrônico. Por isso, foi sugerida uma representação que utiliza diagramas para armazenar e visualizar, além dos dados do paciente, o raciocínio do profissional de saúde durante uma consulta. Essa técnica é conhecida como design rationale, e é usada, principalmente, na área de engenharia de software. Além de propor essas duas novas formas de visualização do prontuário clínico, foi realizado um experimento formal com o objetivo de testar o sumário e o diagrama com DR na prática. O experimento ocorreu em um ambulatório de clínica geral da Unifesp, onde alunos do curso de medicina recebiam o sumário, ou o diagrama com DR, ou o prontuário clínico tradicional e respondiam questões sobre um determinado caso. Os resultados do experimento mostram que o sumário continha informações suficientes para avaliar o quadro clínico do paciente; porém, eles também mostram que o diagrama com DR provavelmente não apresentou nenhuma vantagem em relação ao prontuário tradicional
Abstract: Collaboration between computer science and medicine is growing day by day, and one of the most controversial topics is the electronic patient record (EPR). Despite all scientists agree that the EPR can improve health care quality, how it should behave, or what tools it should provide are still open questions. This work suggests two ways to visualize the EPR. The first is through a summary, with the most important information of the patient. And, the second, is a diagram where the physician is able to express his design rationale. Summarization is a complex problem, and despite very simple procedures were used, the experimental evaluation shows that the summary contains as much information as the traditional EPR. The idea of diagrams to visualize the EPR was originated in a technique called design rationale (DR), used, mostly, in Software Engineering. Its major goal is to reproduce the rationale during a project design. Some researches pointed out that one of the major limitations of EPR is the lack of information about diagnosis processes, and treatment planning. To evaluate these new ways of visualization of the EPR, an experimental evaluation was performed to test the summary and the diagram in real practice. The experiment was conduct in a outpatient care clinic at Unifesp, where medical students use the summary, or the diagram, or the traditional EPR to answer questions about specific patients. The results of the experiment show that the summary was equivalent to the traditional EPR, and that the diagram no not show any leverage to the traditional EPR

Full textAbstract:
Substance abuse has been identified internationally and in South Africa as an escalating problem that has harmful effects on the substance user and on society. The cost of treating substance-related disorders places a strain on the allocation of financial resources to treat the problem. When relapse occurs in substance users who have already undergone rehabilitation, it increases the costs of treatment. Waiting lists at treatment centres are also negatively affected for first-time admissions when relapsed substance users are re-admitted. The study aimed to identify relapse indicators by post-discharge follow-up of adult substance users in a registered, non-profit, state-subsidised treatment facility in Cape Town. Marlatt’s Dynamic model of relapse was used to explore the individual and socio-cultural factors which were potentially associated with relapse. A quantitative research design using archival data and purposive sampling was used to identify possible relapse indicators. The participants were ex-patients who had undergone an inpatient treatment programme and who had been followed up post discharge. Ethical clearance was obtained from the University of the Western Cape Higher Degrees Committee. Written permission was granted by the treatment centre who is the original data owner.The majority of participants were male. More than half of the sample reported polysubstance use and, for more than half of them, the age of onset of substance use was between 11 and 15 years. Severe depression was present for more than a third of the participants, whilst the majority of the sample was assessed as being substance dependent. A large proportion of patients had family members who also used substances. The majority of the sample was unemployed and more than half had received previous substance abuse treatment. Significant associations were not established between the identified variables within the groups of factors. Additional studies are required to explore the factors contributing to relapse in this patient population.Magister Artium (Psychology) - MA(Psych)

Full textAbstract:
For an e-commerce business to grow, there are many ways one could try to improve the business in order to gain greater reach and increase sales. One of the main goals of such businesses is to convert as many visitors as possible into customers. Even though many e-commerce businesses already have web analytics tools installed, e-merchants find difficulty in identifying where to start optimizing, what data to extract from analysis reports, and how to make use of such data in order to produce a successful design that will increase the conversion rate. The purpose of this thesis is to (without spending resources on marketing-related factors) guide companies to find a low cost and efficient way to increase the conversion rate by creating well-thought-through designs based on analytic data, qualitative research, and human-computer interaction principles. Google Analytics, a web analytics tool, was used in identifying high-valued pages to optimize and to identify demographics/target groups, while qualitative e-commerce related research was used to shape design-proposal hypotheses. This, along with two A/B tests conducted using Optimizely, is the basis for the guidelines and conclusions. The results of both A/B tests showed an increase in conversions with designs highlighting: evidence of a secure shopping environment, incentives that will attract visitors to buy, and by removing auxiliary navigation elements at the check-out page. The evaluation of the results and its statistical significance was done using both Optimizely’s statistical engine and null hypothesis testing. The increases in conversions were not statistically significant per Optimizely; however, they were significant using traditional statistics. In conclusion, using metrics such as high exit-rates combined with many page views and high revenue-generating pages will allow e-merchants to identify where to start their optimization process. Furthermore, to know what valuable data needs to be extracted, one should seek the data that needs to be inserted into HCI concepts, such as personas and scenarios. This, along with qualitative research allows designers to create well-thought out design-proposals that will potentially lead to an increased conversion rate.För att få en e-handelsbutik att växa finns det många arbetsområden man kan försöka förbättra för att nå ut till fler samt öka försäljning. Ett av huvudmålen för dessa butiker är att konvertera så många besökare till kunder som möjligt på sin hemsida. Även om många e-handelsbutiker redan har webbanalytiska redskap till sitt förfogande, har många tjänsteleverantörer svårigheter med att fastställa var på hemsidan det skall optimeras, vilken data som ska hämtas från analysrapporter, och hur man använder sig av dessa data för att skapa en lyckad design som kommer öka konverteringsgraden. Syftet med avhandlingen är att, utan marknadsföringsrelaterade investeringar, vägleda företag till billiga och effektiva sätt att öka konverteringsgraden. Detta ska uppfyllas genom att skapa väl genomtänkta designer grundade på analytisk data, kvalitativ forskning, samt människa-datorinteraktions principer. Webbanalysverktyget Google Analytics användes för att identifiera högt värderade sidor att optimera och demografier/målgrupper medan kvalitativ e-handels-relaterad forskning användes för att forma hypoteser kring designförslagen. Detta, tillsammans med två A/B tester som genomfördes med hjälp av Optimizely, är grunden till riktlinjerna och slutsatserna. Resultaten från båda testerna visade en ökning i konverteringar med designer som framhäver; övertygande eller bevis för en säker handelsmiljö, incitament som kommer locka besökare att handla, och genom att ta bort extra navigeringselement vid kassasidan. Utvärdering av resultaten och dess statistiska signifikans gjordes med Optimizelys statistiska motor såväl som egen nollhypotes prövning. Ökningarna av konverteringar var inte statistiskt signifikanta enligt kalkyl från Optimizely, men lyckades nå signifikans enligt traditionell statistik. Sammanfattningsvis, med hjälp av mätvärden så som höga utgångsfrekvenser i kombination med högt antal sidvisningar samt höga intäktsgenererande sidor, kan tjänsteleverantörer nu identifiera var man kan påbörja optimeringsprocessen. För att veta vilken värdefull data man bör extrahera skall man ta reda på vilken data som behövs för att stoppa in i Människa–datorinteraktion (MDI) koncept, som personas och scenarier. Detta, tillsammans med kvalitativ forskning, tillåter webbdesigners att skapa väl genomtänkta designförslag som förhoppningsvis leder till en ökad konverteringsgrad.

Full textAbstract:
This thesis presents a new approach to the long-standing question of how electoral rules influence the behaviour of legislators. It begins with the argument that fresh empirical advances can be made by moving beyond the pervasive but rigid assumption that all legislators want to be re-elected and, by extension, that every incumbent values this goal to the same degree. Rather, I propose that individual Members of Parliament (MPs) vary in the extent to which they personally desire or depend upon re-election. Following the principles of a difference-in-differences design, this observation allows me to devise a theoretical framework capable of testing whether MPs' vote-seeking behaviour differs within parliaments in a way that varies predictably across countries. Specifically, I propose that in electoral systems where party-centric behaviour increases re-election chances, MPs particularly invested in the goal of re-election should cater to the party to an even greater extent than their colleagues. Conversely, in systems where a personal vote can generate electoral gains, MPs most ambitious for re-election should engage in this type of vote-winning strategy to the greatest extent. I test this prediction across the UK House of Commons and the German Bundestag, and within Germany's mixed-member system. Newly-collected biographical data on over 1700 MPs is used to conduct the first systematic MP-level operationalisation of re-election ambition based on legislators' career backgrounds. Career politicians are thereby identified as those most ambitious for re-election. Using voting behaviour from 1.8 million vote choices in legislative roll-calls as a proxy for the degree to which an MP caters to the party or to his or her personal reputation, the quantitative multilevel analysis reveals strong evidence for the proposed behavioural pattern. The contribution made by this study is two-fold. First, it uncovers the interaction between electoral rules and individual re-election ambition as a new explanation for MP-level variation in legislative behaviour. Second, its research design overcomes shortcomings in previous empirical tests for the existing theory on how electoral rules impact MP behaviour (e.g. Carey and Shugart 1995), producing more robust evidence in support of this influential framework.

Full textAbstract:
This study is unique considering the location (Africa) and the industrial setting (Gold Mining) from which the research was studied as reward systems had mostly been studied in the North-American and European settings. Thus, the study considered rewards from the perspective of the African and its natural resource industries such as the gold mining industry. The methodology employed in the study was based on a case study approach at Golden Star (Bogoso/Prestea) Limited (GSB/PL) with a population size of 1029 employees combining both qualitative and quantitative data obtained through a questionnaire survey of a 278 sample size and structured interview with the Human Resources and Administration Manager. Thus, the method of data collection represents methodological triangulation and the data obtained from the study represents a primary source of data. The study revealed that all the three generational groups (Baby Boomers, GEN Xers and GEN Yers) places higher emphasis or priority on financial incentives (high salary and bonuses) over any other incentives when respondents were asked to indicate the reward they prefer most. But when rewards were considered as a total package profile, greater number of the baby boomers placed more emphasis or priority on packages with highly flexible pension benefits, long term job security and high internal promotions eventhough the salary and bonus components of the packages (profile) were not that attract. The GEN X and GEN Y groups still maintained their reward package profile preferences based on high financial incentives, training and learning opportunities, personal growth and career advancement. The study revealed that aside the high preferences for financial incentives such as high salary and bonuses by all the generational groups, few of the GEN X and GEN Y also exhibited other preferences such as high personal growth, flexible work schedule, attractive company policy and administration, career advancement, working environment, job security and praises and recognition of which the baby boomers did not indicate any preferences or interest. The study revealed that all the three generational groups (Baby Boomers, GEN X and GEN Y) consider high salary and bonuses as factor which causes employee dissatisfaction when not satisfied or available but when they are satisfied or available also do not motivate or cause satisfaction and thus confirming Herzberg Two-Factor theory that factors such as salary or remuneration, job security, working conditions and company policies only prevent employee dissatisfaction. The study revealed that all generational groups (baby boomers, GEN X and GEN Y) consider high salaries and bonuses as factor which could lead to lack of satisfaction and motivation of the employee in his current role or position when not available or satisfied and thus this finding confirm the traditional belief that pay is prime, or in some cases the only source of motivation but contradict Herzberg claim that pay (high salaries and bonuses) is only an extrinsic factor and that when is available or satisfied, pay does not bring satisfaction and motivation but rather prevents dissatisfaction. The study revealed that GSB/PL rewards systems basically comprises of extrinsic rewards such as high salary levels (pay increases), a bonus scheme, training and learning opportunities, job security, Stock options, Retirement/Pension benefits such as social security and provident fund, promotions, attractive company policies and administration, praises and recognition, good working environment, flexible work schedule, Long service awards and benefits such as housing, Health insurance, Vacation/Annual leave benefits, transportation/bussing service, messing (provision of meals to employees only when at work), and educational benefits (for employees dependants). The study also revealed that the design and implementation of GSB/PL reward systems involves four distinct phases: assessment, design, execution and evaluation phases. In the end, a suitable conclusion was drawn and a number of recommendations proposed to be implemented by the mining company in safeguarding the interest of both employees and the employer.

Griffis, Brent Patrick. "Multi-Criteria Decision Modeling for Best Value Selections in Target Value Design Integrated Project Delivery." DigitalCommons@CalPoly, 2014. https://digitalcommons.calpoly.edu/theses/1729.
Full textAbstract:
Integrated Project Delivery (IPD) combined with Target Value Design (TVD) is a better way to deliver value for the client than traditional guaranteed maximum price (GMP) methods. With traditional GMP delivery methods, the interests of the parties are often at odds. The goal of IPD is to align all party interests in order to achieve a win-win scenario. Due to the aligning nature of IPD and the fact that each party’s success is dependent on achieving the project objectives as a whole; a non-biased, transparent, decision-making process is necessary in order to deliver the project objectives within the constraints of the TVD. Thus delivering the expected value for the client and ensuring that all parties achieve project success. The need for this transparent decision-making process is compounded by the fact that a “target” based system rapidly declines to a less than optimal state if there is no unbiased decision-making process in place. If we treat the entire lifespan of a project as the complex system that it is, we can begin to take advantage of the hierarchical nature of complex systems. The goal of this paper is to show that by modeling the life span of a project through a multi-criteria decision making model, built on a hierarchical framework will allow you to find a non-inferior solution to your TVD. I’m proposing to use Hierarchical Holographic Modeling (HHM) as the framework for an Analytical Hierarchical Process (AHP) multi-criteria decision-making model complete with post-optimality analysis as the preferred project management method.

Today, few companies would manage to continuously stay competitive without the proper utilization of information technology (IT). This has increased companies’ dependency of IT and created new threats that need to be addressed to mitigate risks to daily business operations. A large extent of these IT-related threats includes hackers attempting to gain unauthorized access to internal computer networks by exploiting vulnerabilities in the behaviors of employees. A common way to exploit human vulnerabilities is to deceive and manipulate employees through the use of social engineering. Although researchers have attempted to understand social engineering, there is a lack of empirical research capturing multilevel factors explaining what drives employees’ existing behaviors and how these behaviors can be improved. This is addressed in this thesis. The contribution of this thesis includes (i) an instrument to measure security behaviors and its multilevel determinants, (ii) identification of multilevel variables that significantly influence employees’ intent for behavior change, (iii) identification of what behavioral governance factors that lay the foundation for behavior change, (iv) identification that national culture has a significant effect on how organizations cope with behavioral information security threats, and (v) a strategy to ensure adequate information security behaviors throughout an organization. This thesis is a composite thesis of eight papers. Paper 1 describes the instrument measuring multilevel determinants. Paper 2 and 3 describes how security knowledge is established in organizations, and the effect on employee information security awareness. In Paper 4 the root cause of employees’ intention to change their behaviors and resist social engineering is described. Paper 5 and 8 describes how the instrument to measure social engineering security behaviors was developed and validated through scenario-based surveys and phishing experiments. Paper 6 and 7 describes experiments performed to understand reason to why employees fall for social engineering. Finally, paper 2, 5 and 6 examines the moderating effect of national culture.QC 20160503

Full textAbstract:
Many companies are using platform-based product designs to fulfill the requirements of customers while maintaining low cost. However, research that integrates sustainability into platform-based product design is still limited. Considering sustainability during platform-based design process is a challenge because the total life-cycle from pre-manufacturing, manufacturing and use to post-use stages as well as economic, environmental and societal performance in these stages must be considered. In this research, an approach for quantifying sustainability is introduced and a mathematical model is developed for identifying a more sustainable platform. Data from life-cycle assessment is used to quantify environmental factors; criteria from the Product Sustainability Index (ProdSI) are used to quantify societal factors. The Analytic Hierarchical Process method is used to assess relative importance of societal factors and the weighted sum method is used in the objective function for overall multi-objective optimization. A bicycle platform configuration will be used as a case study to demonstrate the application of the model. The relationship between commonality of the platform and sustainability performance is analyzed.

The purpose of this study was to determine if the use of educational software contributed to increasing the academic performance of 6th-grade students in mathematics. The specific programs used were the Florida Comprehensive Assessment Test (FCAT) Explorer and Promethean ActivBoard. This summative quantitative study was guided by 3 research questions:
1. What was the effect of technology, specifically the Promethean ActivBoard and the FCAT Explorer, on the achievement in mathematics of 6th-grade students, as measured by district benchmark assessments?
2. What was the difference in mathematics achievement, if any, between male and female 6th-grade students following the use of technology, specifically the Promethean ActivBoard and the FCAT Explorer, as measured by district benchmark assessments?
3. What was the effect of technology, specifically the Promethean ActivBoard and the FCAT Explorer, on the achievement in mathematics of African American 6th-grade students, as measured by district benchmark assessments?
Participants were 6th-grade teachers and students in the experimental and control groups. Participants were 59 students in the experimental group and 61 in the control group. Students who used FCAT Explorer and the Promethean ActivBoard showed better scores on a posttest and larger percentage increase in scores than the control group. Male students in the experimental group showed the greatest increase in scores. African American students who also used FCAT Explorer and the Promethean ActivBoard scored higher than those African American students who did not use any form of technology as a supplement to learning.

O presente trabalho apresenta um modelo de aplicação de ferramentas de projeto integradas ao longo das fases de desenvolvimento de produto, neste caso, aplicadas na melhoria do produto suporte para fixação de cilindro de gás natural veicular. O foco do trabalho é apresentar a integração de ferramentas nas fases de Projeto Informacional, Projeto Conceitual e Projeto Detalhado do Processo de Desenvolvimento de Produtos. Entende-se por integração a escolha de ferramentas que permitam conduzir o fluxo de informação ao longo das fases de desenvolvimento de produtos, de tal forma que a informação de saída de uma ferramenta seja a informação de entrada da ferramenta subseqüente. As ferramentas integradas a partir da fase de Projeto Informacional foram a Pesquisas de Mercado Qualitativa e Quantitativa, com a finalidade de identificar as demandas dos clientes. As demandas dos clientes foram os dados de entrada da Matriz da Qualidade (Quality Function Deployment - QFD), resultando nos requisitos do produto e suas respectivas especificações-meta. A partir dos requisitos do produto, diferentes conceitos (configurações) foram gerados, apoiados pela Matriz Morfológica no Projeto Conceitual. Na seqüência utilizou-se a ferramenta de Projeto de Experimentos (Design of Experiments - DOE) para avaliar a estimativa de preço frente às possíveis configurações do produto. Com a Matriz de Pugh, alternativas de conceito de produto foram avaliadas possibilitando a escolha do melhor conceito de produto. No Projeto Detalhado, foi aplicada ferramenta de Análise dos Modos de Falha e seus Efeitos (Failure Mode and Effects Analysis - FMEA), utilizado de forma integrada com o QFD, para identificar as falhas atuais e potenciais e seus efeitos em sistemas e processo. Em função das demandas identificadas, foram definidas e implementadas melhorias no produto. Observou-se a adequabilidade destas ferramentas de projeto para aplicação de forma integrada, garantindo um fluxo contínuo de informações rastreáveis e que tendem a levar à uma reduzida chance de perdas ao longo do processo.There are few examples in literature about the integration of project tools along the product development phases. The main research objective in thesis is to integrate some tools that facilitate the information flow along the product development phases, more specifically in Informational Project, Conceptual Project and Detailed Project phases. The product improvement “support for Vehicular Natural Gas” was the object of study in thesis. The main idea is that the information output from one tool is the input information of the subsequent tool. Starting from the Informational Project phase it was performed qualitative and quantitative market researches with the purpose of identifying the customers' demands for the studied product. The customers’ demands were the entrance data of the QFD (Quality Function Deployment) tool resulting in the product requirements and their respective specifications-goal. In Concept Project the product requirements were converted in functions and further different concepts were generated through the Morphologic Analysis. In the sequence, it was used the DOE (Design for experiments) tool to evaluate the estimate price to the possible products' configurations. The Pugh Matrix tool was used for concepts evaluation and choice. The FMEA (Failure Mode and Effects Analysis) tool integrated with QFD was useful for current and potential failures identification and impact analysis in the system and process. With the application of these five tools the users’ demands were identified and improvements to the product were performed. The chosen tools proved to be adequate for integration, assuring that a continuous trackable information flow was attained with presumable reduced information loss, along the Product Development Process phases.

Full textAbstract:
This applied dissertation is an instrumental case study based on diffusion of innovations theory designed to gather student opinions regarding videoconference (VC) technology use in facilitating courses to undergraduate degree-seeking nursing students. The author of diffusion of innovations theory, Rogers (2003), recommended that more qualitative studies be conducted in education. Rogers and Jain (1968) recommended these studies should be conducted from the aspect of “receivers of innovation diffusion” (p.1) to provide feedback instrumental to implementation of technological innovations in academe. Further, Rogers stated that multiple data points should be used during the process of trialing an innovation. Therefore, a current VC course was selected from the nursing curriculum of a public state college hosting one of the largest nursing programs in the southeastern United States in which to conduct the study.
A total of 32 students participated divided equally between two sites: Main campus and Regional campus. Further divided, 22 personal interviews were conducted and two focus groups; one for each campus consisting 5 students each. Additionally, included in the data corpus were 40 hours of classroom observation plus, college provided end of course (EOC) summary statements. These data were triangulated to determine whether students would accept VC technology unchanged, accept with modifications, or reject VC technology based on first time exposure to the innovation during the 16-week semester. Student innovation decisions were: 6 students accepted unchanged, 14 students accepted with modifications, and 12 students rejected the innovation. Students who rejected the innovation were exclusively from the regional campus, which was the receiving site the majority of the semester.
First and second-cycle analyses yielded 67 codes resulting in 5 categories, which further developed into 3 emerging themes: (a) Interaction with instructors, materials, and distant students are key elements affecting adoption decisions of students regarding VC technology; (b) Student adoption decisions are influenced by faculty members in their use of VC technology; and (c) Student opinions indicate that reinvention is necessary for VC technology to be fully adopted into the present nursing program. The five categories: Interaction, equipment, teaching methodology, instructor technology training, and student orientation provided ample detail from which to inform practice regarding recommendations for reinvention (modification) of VC technology during the implementation stage of Rogers’ five stages of the innovation-decision model. These modifications could assist the college in gaining parity between the two nursing sites, which reported an 18.53 percentage point difference in first time pass rates on the NCLEX-RN exam reported by the Florida Department of Health (Florida Health, 2015).

INTRODUÇÃO: A rinite alérgica é uma condição clínica comum que apresenta sintomas diversos num significante número de pacientes, deteriorando a qualidade de vida daqueles refratários aos tratamentos usuais (anti-histamínicos e corticosteróides nasais tópicos). Apresentando princípios curativos similares, a imunoterapia sublingual e a homeopatia podem reduzir os sintomas e a necessidade de medicamentos na rinite alérgica, embora a eficácia e a efetividade de ambas terapêuticas não sejam ainda suficientemente conhecidas. OBJETIVOS: O objetivo deste estudo foi avaliar a efetividade clínica do tratamento homeopático individualizado prolongado, comparativamente ao placebo, em adultos portadores de rinite alérgica perene. MÉTODOS: Um total de 41 pacientes com rinite alérgica perene foi alocado numa primeira fase duplo-cego e placebo-controlada durante seis meses, sendo tratada com doses sublinguais semanais de medicamentos homeopáticos individualizados ou placebo. Após esta fase inicial fechada, todos os pacientes foram convidados a participar de uma segunda fase controlada aberta, em que receberiam tratamento homeopático pelo período máximo de 36 meses, e os resultados foram comparados com a melhora da fase inicial. O escore dos sinais e sintomas, a necessidade de medicamentos de resgate e a qualidade de vida foram mensurados por questionários e avaliações clínicas pessoais, aplicadas por um mesmo avaliador independente, antes e após cada fase. As doses dos medicamentos homeopáticos e de resgate utilizados, assim como os efeitos colaterais, foram documentados num diário pessoal. Os desfechos clínicos primário e secundários foram, respectivamente, os escores dos sinais e sintomas alérgicos específicos e gerais. Títulos da IgE total foram mensurados antes e após cada fase. RESULTADOS: Após os seis meses da fase placebo-controlada inicial, na análise por protocolo de todos os pacientes incluídos no estudo, não foram observadas diferenças significativas entre os grupos ativo e placebo nos escores clínicos, na utilização de drogas de resgate, na qualidade de vida e nos títulos da IgE total. Entretanto, as análises dos subgrupos da segunda fase mostraram uma crescente e significativa melhora nos desfechos clínicos primário e secundários após 12 meses de tratamento homeopático individualizado, comparativamente à variação de melhora dos mesmos pacientes na fase inicial fechada. Diferença significativa na qualidade de vida foi observada apenas após o segundo ano de tratamento homeopático. CONCLUSÃO: Neste estudo, o tratamento homeopático foi acompanhado de um significante efeito placebo. A efetividade da homeopatia pôde ser observada após 12 meses da terapêutica, apresentando efeito preventivo de longa duração após 36 meses de tratamento homeopático individualizado.INTRODUCTION: Allergic rhinitis is a common clinical condition which presented several symptoms in a significant number of patients, deteriorating the quality of life in those resistant to the usual treatments (antihistamines and topical nasal corticosteroids). Presenting similar curative principles, sublingual immunotherapy and homeopathy can reduce symptoms and medication requirements in allergic rhinitis, although the efficacy and effectiveness of both therapeutics are not still sufficiently known. OBJECTIVES: The objective of this study was to evaluate clinical effectiveness of prolonged individualized homeopathic treatment, compared with placebo, in adults with perennial allergic rhinitis. METHODS: A total of 41 adults with perennial allergic rhinitis were enrolled in a first double-blind placebo-controlled phase for six months, and treated on a weekly basis with sublingual doses of single individualized homeopathic medicines or placebo. After this closed initial phase, all patients were invited to participate in an open label controlled phase, in that they would receive homeopathic treatment for the maximum period of 36 months, and the results were compared with the improvement of the initial phase. Signs and symptoms scores, rescue medication requirements and quality of life were assessed by questionnaires and personal clinical evaluation by a same independent researcher, before and after each phase. Applied homeopathic and rescue drugs dosage, and side effects were documented by diary cards. Primary and secondary clinical outcome were, respectively, specific and general allergic signs and symptoms scores. Total IgE titles were performed before and after each phase. RESULTS: After six months of placebo-controlled phase, analyzing all patients included in the study per protocol, we observed no significant difference between treatment and placebo groups in primary and secondary clinical outcomes, use of rescue drugs, quality of life and total IgE. However, second phase subgroups analysis showed a significant and growing improvement of clinical symptoms after 12 months of individualized homeopathic treatment, comparatively to the same patients\' variation in closed initial phase. Significant difference in quality of life score were observed only after second homeopathic treatment year. CONCLUSION: In this study, homeopathic treatment was accompanied by a significant placebo effect. Effectiveness of homeopathy could be seen after 12 months of therapy, presenting preventive effect of long duration after 36 months of individualized homeopathic treatment.

Full textAbstract:
The rise of “zero tolerance” discipline practices in US primary and secondary schools has become increasingly well documented by the media and empirical studies. Despite the extensive scholarship that has emerged from these conversations, many of these analyses are limited in their scope and do not connect the phenomena of zero tolerance in schools to the diverse, shifting forces at play within American politics and policy today. As such, the goal of this work is to synthesize ideas about zero tolerance across disciplines by integrating historical thought, philosophical frameworks of punishment, shifting policy goals within the US education system, the sociological constructions of “deviance” and “disorder” in the context of the US criminal justice system, and empirical data directly from a school district to develop particular policy recommendations accordingly. The primary research question of this analysis is: What are the effects of zero tolerance discipline policies on educational outcomes? To answer this question, Chicago Public Schools will be employed as a case study from which lessons for the nation at large will be drawn. Ultimately, this analysis ends up revealing the ways in which zero tolerance policies stem from much deeper forces at play between dominant and marginal groups, and what comes to be defined as “deviance” in relation to a socially constructed system of “order.”

Full textAbstract:
A wide range of research fields have studied how emotions and behavior are affected by the physical environment. This gestalt theorist approach of experimental research as well seeks to measure emotion (using the valence-arousal scale) and micro-scale community development interactions when weighted physical environment factors are adjusted. Community development (CD) interactions at the micro-scale have received but slight attention from scholars in the CD research field and this study aims partially to investigate developing objective measures from social observations. CD interactions from recordings along with self-reported emotion through surveys in four quasi-experimental groups (where the environments were constructed based on peer-reviewed literature to cause emotional reactions) and one control group made up the data collected for this experiment. While the results of this experiment displayed apparent convincing quantitative differences in both CD interactions and emotion when the physical environment was manipulated, the results of a one-way ANOVA indicated no statistical significance to either dependent variable. The conclusions suggest limiting the physical factors of the environment to produce more precise changes as a result of the manipulated quasi environments.

View John Huân Vũ's thesis presentation at http://youtu.be/y3bzNmkTr-c.
In 2001, the ACM and IEEE Computing Curriculum stated that it was necessary to address "the need to develop implementation models that are international in scope and could be practiced in universities around the world." With increasing connectivity through the internet, the move towards a global economy and growing use of technology places software internationalization as a more important concern for developers. However, there has been a "clear shortage in terms of numbers of trained persons applying for entry-level positions" in this area. Eric Brechner, Director of Microsoft Development Training, suggested five new courses to add to the computer science curriculum due to the growing "gap between what college graduates in any field are taught and what they need to know to work in industry." He concludes that "globalization and accessibility should be part of any course of introductory programming," stating:
A course on globalization and accessibility is long overdue on college campuses. It is embarrassing to take graduates from a college with a diverse student population and have to teach them how to write software for a diverse set of customers. This should be part of introductory software development. Anything less is insulting to students, their family, and the peoples of the world.
There is very little research into how the subject of software internationalization should be taught to meet the major requirements of the industry. The research question of the thesis is thus, "Is there a framework for software internationalization that has been validated against industry requirements?" The answer is no. The framework "would promote communication between academia and industry ... that could serve as a common reference point in discussions." Since no such framework for software internationalization currently exists, one will be developed here. The contribution of this thesis includes a provisional framework to prepare graduates to internationalize software and a validation of the framework against industry requirements. The requirement of this framework is to provide a portable and standardized set of requirements for computer science and software engineering programs to teach future graduates.

The study’s conceptual frameworks were the objectives of the Regulation R.425 programme and the scope of practice of professional nurses. The study sought to reveal whether the NPNs were competent in health education and in identifying barriers to health education, and to make recommendations. A structured questionnaire was used for data collection from the professional nurses in supervisory roles. The data was analysed using the Statistical Package for the Social Sciences (SPSS) version 21.0 program.
The results revealed that NPNs were competent in health education, however, paid less attention to family involvement and patients’ level of education (a barrier to health education).

This paper brings critical sociological analysis of contemporary situation on the EMS field in Czech Republic and discovers several topics which seemed to be less emphasized at that time. The result of the study is complex description of the EMT's personality, particular types, the population as a whole, specific relationships between variables and a few problems identified during the survey. Using mixed design research methods, the author deals with the emergency medical services in Czech Republic and it's employees. Based on the narrative data collected in speeches with the EMS staff, the typology of EMT's was created, considering their work attitudes, and a set of hypothesis was created as well. On this basis the continuing quantitative research was designed, verifying the validity of previous findings. The paper offers possible directions, how to continue in forthcoming research.

Magister Psychologiae - MPsychThe outcome of child abuse, i.e. physical, emotional and/or sexual, and child neglect is multifactorial. The severity, duration and nature of abuse and the child’s vulnerabilities are all contributory factors with regards the outcome of abuse. Children who are traumatized are likely to be profoundly affected. Studies have shown and nearly every researcher agrees that early childhood traumas lie at the root of many emotional and psychological illnesses. It has been noted that drug abuse is a major problem in the Western Cape. This thesis explored the relationship between subjectively perceived childhood trauma and drug dependence in an in-patient treatment-seeking sample of adults in the Cape Town Metropolitan Area in the Western Cape. This thesis presents the results of a measure of childhood trauma, namely the Childhood Trauma Questionnaire [CTQ] and a measure of drug dependence, the Drug Use Disorder Identification Test [DUDIT]. The sample consisted of 52 participants and included both males and females. Only participants who were identified as drug dependent were included in the study. Patients who were actively psychotic and/or alcohol dependent were not included in the study. Ethical clearance was obtained from the University of the Western Cape’s higher degree ethical committee. The anonymity of the participants, the importance of responding openly and honestly and the sensitive nature of the questions were highlighted during the test administration. Questionnaires were administered in accordance with the guidelines stipulated in the respective manuals. The data was analysed through correlation. The study found a positive correlation between childhood emotional abuse and drug dependence, and childhood physical abuse and drug dependence.

This study was conducted in order to assess the effects of creative stimulation in early childhood. The quantitative quasi-experimental study was set out to test a target group of 8 children in grade R, ranging in age from five to six years, to determine the importance of stimulation and intervention of creativity from a young age. A pre-test, evaluated the initial level of each child’s creative skills in fluency, flexibility and originality. This was followed by selecting one class as the experimental group and another class, from the same demographical location, as the control group. The experimental group underwent a six-week intervention programme which focused on the primary concepts in each area of fluency, flexibility and originality. Both groups continued with their normal school learning programmes. The results indicate that the impact of stimulation on young children was significant and that there was a great difference in the abilities and understanding of concepts in those children whohad been stimulated.Teacher Education

Full textAbstract:
Text in EnglishDevelopments in Internet technology and pervasive computing over the past two and half decades have resulted in a variety of Web-based applications (WBAs) that provide products and services to online users or customers. The Internet is used not only to transfer information via the web but is increasingly used to provide electronic services including business transactions, information-delivery and social networking, as well as e-government, e-health and e-learning. For such organisations, e-service quality, usability and user experience are considered to be critical determinants of their products’ or services’ success. Many studies to model these three concepts separately have been undertaken as part of broader studies of software quality or service quality modelling. However, to the current researcher’s knowledge, none of the studies have focussed on proposing an evaluation model that integrates and combines the three of them. This research is an effort to fill that gap. The primary purpose of this mixed-methods research was to develop a conceptual integrated model for evaluating e-service quality, usability and user experience (e-SQUUX) of WBAs and then contextualise it to evaluation of a University web portal (UWP). This was undertaken using an exploratory sequential research design. During a qualitative phase, an extensive extensive systematic literature review of 264 relevant sources relating to dimensions of e-service quality, usability and user experience, was undertaken to derive an integrated conceptual e-service quality, usability and user experience (e-SQUUX) Model for evaluating WBAs. The model was then empirically refined through a sequential series of validations, thus developing various versions of the e-SQUUX Model. First, it was content validated by a set of four expert reviewers. Second, during the quantitative phase, in the context of a University web portal, a questionnaire survey was conducted that included a comprehensive pilot study with 29 partipants, prior to the main survey. The main survey data from 174 particiapants was used to determine a validated model, using Exploratory factor analysis (EFA), followed by producing a structural model, using partial least square – structural equation modelling (PLS-SEM). This version consisted of the components of the final e-SQUUX Model. Consequently, the research enriches the body of knowledge on IS and HCI by providing the e-SQUUX Model as an evaluation tool. For designers, developers and managers of UWPs, the model serves as a customisable set of evaluation criteria and also provides specific recommendations for design. In line with the Exploratory sequential design of mixed methods research, the findings of the qualitative work in this research influenced the subsequent quantitative study, since the potential Likert-scale questionnaire items were derived from the definitions and meanings of the components that emanated from the qualitative phase of the study. Consequently, this research is an exemplar for developing an integrated evaluation model for specific facets or domains, and of its application in a particular context, in this case, a University web portal.

Die probleem van armoede is aangespreek deur middel van die groepwerkproses, waardeur mense sodanig bemagtig is dat die kringloop van armoede verbreek kon word. 'n Kwasi-eksperimentele navorsingsontwerp is gebruik met die groepwerkprogram as onafhanklike veranderlike en die algemene tevredenheid en graad van bemagtiging van die groeplede as die afhanklike veranderlikes. Slegs die voorondersoekgroep en twee eksperimentele groepe is aan die program onderwerp, maar nie die kontrolegroepe nie. n Voor- en natoets is deur aldie groeplede voltooi, om kwantitatiewe data te versamel. K walitatiewe data is versamel deur deelnemende waarneming en doelgeribte gesprekvoering. Die belangrikste verskil tussen die resultate van die eksperimentele groepe en die kontrolegroepe, was dat eersgenoemde tot aksie oorgegaan het terwyllaasgenoemde passief gebly het. Die gevolgtrekking kan dus gemaak word dat die groepwerkprogram wei tot die bemagtiging van die groeplede gelei het wat aan die program onderwerp was.

The problem of poverty was addressed through the group work process, in order to empower people so that the cycle of poverty could be broken. A quasi-experimental design was used with the group work programme as the independent variable and the general contentment and degree of empowerment of the group members as the dependent variables. Only the pilot study group and the two experimental groups were exposed to the programme, while the two control groups were not. Pre- and posttests were taken of all the group members to gather quantitative data. Qualitative data was gathered by means of participant observation and purposeful conversation. The most important difference between the different groups was that action was taken by the groups subjected to the programme, whereas the control groups remained passive. It can thus be concluded that the group work programme was instrumental in empowering those group members exposed to the programme.

In the light of the child's self-esteem that is affected by traumatic events, the goal of the research was to explore and describe the self-esteem of children orphaned by HIV/AIDS. The researcher made use of a quantitative research method. 30 (N=30) respondents, both male (n=16) and female (n=14), between the ages of 11 to 15, were randomly sampled for inclusion in the study. Each participant completed a self-report measure of self-esteem, The Culture-free Self-esteem Inventory for Children, which yielded a score of Global Self-esteem, as well as in four sub-domains including: General, Social, Academic and Parent-related Self-esteem.
The results of this study demonstrated that the participants experienced a lowered self-esteem. These findings were explored in light of a literature review, after which conclusions and recommendations were provided.Social Work
