Full textAbstract:
The aim of this thesis is to propose a design and implementation of a new product in the field of parcel services in the Czech Post and propose its communication strategy. The basis for correct and efficient product design theme consists of description of the main postal market aspects and principles in the Czech Republic and detailed monitoring and analysis of domestic and global competition and customer environment. This, together with a summary of the basic theoretical approaches to the field of marketing and commercial communication forms the basis for designing a communication strategy. Results of this work confirmed that the proposed new product "Předplacené balíkové obaly" is a promising service that could help the Czech Post in the growing competitiveness in the field of express parcel delivery. Succes of its implementation will largely depend on the ability of the Czech Post effectively inform customers. Communication campaign, however, must reflex and develop the previous link of the "Great Parcel Revolution ".

Full textAbstract:
PostIB tillhandahåller en produkt som skall kunna lämna en notifikation när brev eller paket anlänt till mottagarens brevlåda. Dessa notifikationer skall presenteras hemma för användaren. Då produkten inte finns på svenska marknaden, sattes projektplanen upp tillsammans i projektgruppen, där mål och krav definierades. Arbetsprocessen inleddes med en marknadsanalys samt en kundundersökning, för att ta reda på samtliga möjliga lösningar för denna produkt. Genom kundundersökningen kunde man ta reda på vad potentiella kunder skulle vilja ha för funktioner i produkten. Den slutgiltiga rapporten i marknadsanalysen visade att befintliga produkter finns, men saknade en del av vad projektgruppen söker. PostIB plattform konstruerades samt utvecklades på ett sådant sätt där möjlighet för vidareutveckling finns. Då produkten inte är likt marknads konkurrenter, är denna innovation mer anpassad för den digitaliserade marknaden. Projektet delades upp i olika faser för att uppnå ett framgångsrikt resultat av produkten. En planering över hur arbetet skulle gå till väga utfördes, där funktioner och algoritmer sattes upp. Den andra delen av arbetet var struktur och konstruktion. Under denna del fick projektgruppen göra en utvärdering av samtliga sensorer samt implementera konstruktionsfasen. I avslutande fas av projektet sammanfogades samtliga delar, där en slutgiltig prototyp presenterades. Slutresultatet av produkten resulterade en slutgiltig funktionell prototyp som kan skicka en notifikation i form av en signal till en mottagare som i sin tur presenterar signalen grafiskt på ett användargränssnitt. Prototypen motsvarade projektgruppens förväntningar men hade önskats att utvecklas ännu mer utifrån gruppens preferenser. Dessa önskemål bedömdes slutligen som ett projekt för vidareutveckling.PostIB provides a product that should be able to provide a notification when a letter or package arrives at the recipient's mailbox. These notifications must be presented to the user at home. As products are not available on the Swedish market, the project plan was put together in the project group, where goals and requirements are defined. The work process began with a market analysis and a customer survey, to find out all possible solutions for this product. Through the customer survey, it was possible to find out what potential customers would like for features in products. The final report in the market analysis showed that existing products exist but lacked part of what the project group is looking for. PostIB platform was designed and developed in such a way where there is opportunity for further development. As the product is not like market competitors, this innovation is more adapted to the digitalized market. The project was divided into different phases to achieve a successful result of the product. A planning of how the work would proceed was carried out, where functions and algorithms were set up. The second part of the work was structure and construction. During this part, the project team had to make an evaluation of all sensors and implement the design phase. In the final phase of the project, all parts were joined together, where a final prototype was presented. The end result of the product resulted in a final functional prototype that can send a notification in the form of a signal to a receiver which in turn presents the signal graphically on a user interface. The prototype met the project group's expectations but had wanted to develop even more based on the group's preferences. These wishes were finally assessed as a project for further development.

Janíčko, Martin. "Essays on Financial Innovation, Credit Constraints, and Welfare." Doctoral thesis, Vysoká škola ekonomická v Praze, 2010. http://www.nusl.cz/ntk/nusl-165930.
Full textAbstract:
The submitted thesis is composed of three different articles dealing with issues of financial innovation, credit constraints, and their impact on welfare. The first article treats the contemporary theoretical grasp of the interaction between the financial and real economies, focusing primarily on the role of modern financial innovation in the business cycle. For this purpose, a framework promoted by the Regulation School and Post Keynesians is frequently employed, whilst some other unorthodox streams and mainstream economics are partially discussed as well. All of them aspire -- either per se or under the pressure of the contemporary economic agenda -- to clarify the evolution of financial innovation and credit in the recent era. It is generally found that certain consensus across the schools of economic thought exists, but some of them have done a better job in predicting the consequences of the financial innovation for real economic activity than others. Further, two dynamic macroeconomic models are developed in order to, inter alia, identify the possible effects of extended credit availability presented in the former article on the example of the housing market, and simulate the effects of housing price changes on general welfare. Clearly, this part of the thesis exhibits the indirect consequences of financial innovation as, once again, being rather ambiguous: after having partially unleashed the unprecedented credit granting in the economy, impacting interest rates and loan-to-value ratios, with a subsequent impact on housing prices, it has also influenced credit constrained and unconstrained households in a different manner. Based on an analysis of the situation using partial and general equilibrium analytical frameworks, two somewhat different conclusions are drawn up with respect to the occurrence of various shocks in the models. Under the partial equilibrium framework the effects of relaxation of credit constraints are visible and quite straightforward, indicating relatively simple and intuitive relationship between the price appreciation and general welfare. This is primarily perspicuous for the credit constrained households. In the general equilibrium framework, on the other hand, the transitional dynamics of shock proliferation is more transparent and the impact on credit constrained vs. unconstrained households is more ambiguous and much different from the basic intuition used in the article anchored in the partial equilibrium toolbox.

Full textAbstract:
The present work explores my practice as a photojournalist researching anthropological issues in the Muslim world. I use the Hawzas, the Muslim Shi’a seminaries, as my case study to invite a visually informed approach to the human sciences, and promote a practical usage of aesthetics. Because of the dramatic disproportion between socio-cultural relevance and under-representation, the Hawzas offer an extremely valuable opportunity to research issues of Orientalism and Orientalist visual archives. By questioning my own fieldwork practice alongside the visual signification of the Hawzas, I reconnect the pre-production to the post-production phase, and encompass within it a shared outlook issues of both the Real and the represented. I posit the photograph within wider multimedia and multi-audience practices as a stand-alone communicative device and part of a montage to assess its communicative features in relation to the verbal as a caption, and to the visual, in montage. Through this, I distinguish a phenomenological framework of analysis to urge a radical rethinking of personal and social agencies, and suggest the notion of communicative hubs for today’s globalised identities. I evince the extent to which the digital is reshaping forms of visual-led and multimedia production, knowledge distribution and media consumption to finally contextualise the photograph as ‘semantics without ontology.’ I conclude by advocating my ideas of the ‘Meta- Image’ and ‘Public Cultures 2.0’ as two integrated formats for visual-led communication, digital media practice, social engagement and public impact as specifically addressing Muslim cultures.

Full textAbstract:
Electron beam melting (EBM), a metal additive manufacturing (AM) process, has received considerable industrial attention for near net shape manufacture of complex geometries with traditionally difficult-to-machine materials. This has fuelled considerable academic interest in investigating EBM of Alloy 718, a nickel ironbased superalloy possessing an exciting combination of good mechanical behaviour and cost effectiveness. EBM production of Alloy 718 is particularly promising for aerospace and other sectors which value rapid production of components with large scope for design flexibility. The EBM builds are characterized by presence of inevitable defects and, anisotropy within a build is also a concern. Consequently, as-built Alloy 718 has to be subjected to post-build thermal-treatments (post-treatments) to ensure that the parts eventually meet the critical service requirements. Not withstanding the above, limited knowledge is available about optimal post-treatments for EBM-built Alloy 718. Therefore, the main focus of the work presented in this thesis was to systematically investigate the response of EBM-built material to post-treatments, which include hotisostatic pressing (HIPing), solution treatment (ST), and aging. HIPing of EBM-built Alloy 718 led to more than an order of magnitude reduction in defect content, which was reduced from as high as 17% to < 0.2% in samples built with intentionally introduced porosity to investigate limits of defect closure achievable through HIPing. In addition, HIPing also caused complete dissolution of δ and γ" phases present in the as-built condition, with the latter causing dropin hardness of the material. HIPing had no effect on the carbides and inclusions such as TiN, Al2O3 present in the built material. The evolution of microstructure during ST and aging was systematically investigated. Growth of potentially beneficial grain boundary δ phase precipitates was found to cease after a certain duration of ST, with samples subjected to prior-HIPing exhibiting lesser precipitation of the δ phase during ST. While the specimen hardness increased onaging, it was observed to plateau after a duration significantly shorted than the specified ASTM 'standard' aging cycle. Therefore, prima facie there are promising prospects for shortening the overall heat treatment duration. A combination of HIPing, ST, and aging treatments in a single uninterrupted cycle was also explored. Future work involving incorporation of a shortened heat treatment schedule in a combined cycle can have significant industrial implications.Articles submitted to journals and unpublished manuscripts are not included in this registration

Kassam, Shinan N. "One explanation for why farmers produce cotton collectively in post-Soviet Tajikistan." Thesis, University of British Columbia, 2011. http://hdl.handle.net/2429/36114.
Full textAbstract:
In post-Soviet Tajikistan, a heavy concentration on collective cotton production is argued to be based upon vested interests, a cash short economy, historical and political economy reasons. Given challenges in the set up of a functional land cadastral system, access to rural credit can be facilitated through the currency that raw cotton provides as collateral against production loans. While there are other relatively more profitable options for agricultural production, a certain amount of land is placed under cotton, in order to secure financing for non-cotton production. The lender advances credit for cotton production, but a portion of this credit is diverted out of cotton and into non-cotton production. Non-cotton production is not collateralized and results in a private gain for individual members within the “collective”. The lender has full knowledge of this diversion and compensates by pushing a higher level of in kind credit than is needed for the amount of land dedicated to cotton. Accumulating “debt” has become a defining feature of the cotton sector, but I argue that an appropriate definition is non conventional. This is particularly important given that loans are extended over consecutive seasons despite accumulating “debt”. “Debt” can more accurately be defined as the cost of doing business for the lender, who ties together the services of loan provision with that of marketing cotton. Using original copies of farm invoices, state statistics, key informant accounts, as well as secondary survey data, I argue that there is ostensibly little difference in the standard of living between farmers engaged in diversified cropping systems (cotton and non-cotton) and those engaged solely in non-cotton production. In an economy where markets for credit and productive inputs are thin and erratic, the manner in which credit is advanced plays a large role in fostering this indifference. This argument is somewhat different than the prevailing view, which takes the position that cotton “debt” is a constraining factor in the development of the agricultural sector in Tajikistan. One explanation for why Tajik farmers collectively produce cotton at a loss is that it is privately profitable to do so.

Full textAbstract:
This study presents a two-step desalination process, in which produced water is cleaned by forming gas hydrate in it and subsequently dewatering the hydrate to remove the residual produced water trapped in between the hydrate crystals. All experiments were performed with pressure in the range of 450 to 800psi and temperature in the range of -1 to 1°C using CO? as guest molecule for the hydrate crystals. The experiments were conducted using artificial produced waters containing different amounts of NaCl, CaCl₂ and MgCl₂ at varying temperature (T) and pressure (P). The results are presented as functions of %Reduction of difference chemical elements, CO? requirements and applied T and P conditions.
The impact of dewatering techniques, including centrifuge and filtration process, on gas hydrate solid product is studied. The results showed that over 99% of dissolved NaCl and MgCl2 can be removed from artificial saline water in laboratory experiments. This was achieved in a process involving a single-stage hydrate formation step, followed by a single-step solid-liquid separation (or dewatering). The results also show that the %Reduction (percentage of the concentration decrease) of artificial produced water increases with centrifugation time and rotational speed (rpm). The %Reduction was increased considerably after hydrate crystals were crushed and filtered, indicating that the artificial process water was entrapped in between the hydrate crystals. It was found also that the finer the particle size, the higher the extent of salt removal. In general, filtration was a better than centrifugation for the removal of TDS (Total Dissolved Solids).Master of Science

Full textAbstract:
Fresh leafy salads suffer from post-harvest microbial contamination and decay. Due to increasing pesticide resistance and consumer pressures, residue free alternatives, such as ozone, are being actively explored and encouraged to reduce microbial loads of crops in storage/transit. Previous work has demonstrated that long-term exposure to low concentrations of ozone can be effective in retarding the degradation of some fruit and vegetable. Much less is known about the potential of ozone-exposure to protect leafy produce. The first goal of this project was to determine ozone exposure levels that did not damage produce, but reduced microbial loads significantly. Different produce types exhibited varying abilities to resist ozone damage, e.g. coriander and rocket were relatively resistant to ozone (10 ppm for 10 min); while spinach, watercress and lettuce were more sensitive (1 ppm for 10 min). These ozone exposure levels reduced bacterial loads by at least 1-log. Confocal microscopy confirmed that some bacterial cells (1−10%) survived ozone treatment. These visual observations demonstrated heterogeneity in the resistance of the leaf surface microflora to ozone treatment. It was tested if colony age and/or stress (e.g. cold) may be responsible for the variation in ozone resistance observed. Stressed cells of Pseudomonas sp. isolated from coriander exhibited greater resistance to ozone than control cells. Subsequent gene expression analysis using RNA-Seq technology of stressed cells showed significant changes in the expression of genes related to stress resistance compared to controls. In particular, it was observed that in aged colonies, about 90% of the changes in gene expression mapped to one gene, a non-coding RNA that is part of RNase P. Many of the genes showing differential expression were involved in energy production and transport, motility or cell wall/membrane integrity. This improved mechanistic understanding of ozone resistance may lead to novel anti-microbial treatments. As there are growing concerns about the contamination of leafy products with pathogens resulting in food poisoning the final part of this work focused on the potential of ozone to inactivate food pathogens on leafy produce. Results showed that this treatment significantly reduced E. coli and Listeria spp. on spinach, and the pathogens did not re-grow after treatment over a 9-day storage period. v It was concluded that gaseous ozone treatment is worthy of further exploration as a potential commercial tool to improve the safety of fresh leafy salads and herbs, and reduce microbial spoilage.

Yesiloglu, Sevil. "To post or not to post : examining motivations of brand/product-related engagement types on social networking sites." Thesis, Bournemouth University, 2018. http://eprints.bournemouth.ac.uk/30263/.
Full textAbstract:
At present, consumers use social networking sites to engage with brands and brand related content, this study examines consumers’ motivations for brand/product- related engagement on social networking sites. This thesis develops three motivation frameworks to explain each brand/product-related engagement type: consuming, contributing and creating. The main objectives are: 1) to understand what motivates consumers to engage with different brand/product-related posts on social networking sites, and 2) to understand the relationship between brand/product-related engagement types and social networking sites usage. A mixed-methods approach is employed through establishing exploratory sequential research design. First, consumers’ motivations drawn from psychology and brand/product-related engagement literature are defined through using semi- structured interviews (N=12) in order to define the factors behind each brand/product-related engagement type on social networking sites. Then, the findings of semi-structured interview analysis lead to the development of web-based questionnaires. Web-based online questionnaires (N= 225) were conducted in order to examine motivations of each brand/product-related engagement type on social networking sites and the relationship between brand/product-related post engagement and social networking site usage. A survey of 225 respondents was conducted and analysed using quantitative method. The findings shed light on the reasons behind consumers’ brand/product-related engagement types (e.g. consuming contributing, creating) on social networking sites, and the relationship between consumers’ social media site usage and brand/product- related engagement behaviour. A key contribution of this thesis is to construct five models: 1) a motivation framework for consuming brand/product-related posts from brands which aims to explain what motivates consumers to consume (e.g. read, view) brand/product-related posts from brands; 2) a motivation framework for consuming brand/product-related posts from other people; 3) a motivation framework for contributing brand/product-related posts from brands and other people that examines factors behind consumers’ contribution behaviour to brand/product- related posts through sharing, commenting, liking, favouriting, tagging, etc; 4) a motivation framework examining the motives of consumers for creating positive brand/product-related posts on social networking sites; and 5) a motivation framework defining the motives of consumers to create negative brand/product-related posts on social networking sites. The findings also define brand/product-related engagement types and social networking site usage. The relationship between social networking site usage and brand/product-related engagement is only found for two engagement types: consuming and contributing.

Full textAbstract:
UX-related issues is one type of issue that customer support is facing. This thesis project investigates the possibility to look at support cases as a source of insight to how users interact with an information system application at an ERP company. It is also investigated if it is possible to use this gathered information when further developing the product. Support case data are gone through in order to map what type of problems the users are encountering and a category structure is developed based on this information. The categorization framework is evaluated by letting employees test the structure by categorizing incidents in to different categories. Further data collection are gathered by a questionnaire and follow-up interviews with the classification participants. To evaluate the value in the support case information, employees with product responsibility are also interviewed to get insight from their perspective. The result from the evaluation of the category structure indicated that it wasn’t easy to make a categorization of incidents. The incidents were placed in different categories and in order to apply a category structure it would need further evaluation before applying in large scale. The information in support cases are concluded to be valuable. The collection of information related to where users are encountering problem and also how many are experiencing the same issue could serve as a basis when prioritizing the product backlog. A mapping of issues could justify resources spent on usability by showing business value based on the presumed impact.

Full textAbstract:
Given issues in education concerning teacher shortages, the omnipresence of alternative certification programs and the growth of online programs in higher education, this study investigated teacher retention for 77 secondary education teachers who completed an online teacher preparation program in Texas. Teacher retention was examined from 2003-2013 and investigated the influence of factors such personal characteristics, working conditions and school setting characteristics on teacher retention. Data was collected electronically utilizing a survey instrument designed by two teacher education experts and I. A total of 21 variables and two open-ended questions were investigated using the survey instrument. Exploratory factor and hierarchical multiple regression analyses were conducted to identify a multi-factor model for teacher retention utilizing the participants' survey responses. These analyses yielded evidence of the program's effectiveness in preparing teachers for long careers. Specifically, the areas of program support, field experience, and classroom management were statistically significant factors that contributed positively to teacher retention. Additionally, variables outside the program, were examined. These factors included personal characteristics, working conditions, and school setting factors. The predictor model accounted for 56% of the variance; F (17, 54) = 3.015; p = < 0.001. In particular, working conditions contributed to 41% of the variance associated with the teacher retention model. A qualitative analysis of open-ended survey questions was used to further examine decisions to remain in teaching. Support of administration, colleagues, staff, and parents was shown to influence teacher retention.

Full textAbstract:
Traditionally, Ti-6Al-4V components are fabricated by forging or casting. However, these methods of production require expensive dies or molds. The cost per part is very high for those parts produced in low quantities. The solid freeform electron beam melting process aims to produce high dimensional tolerance parts with similar mechanical properties at a lower cost by melting Ti-6Al-4V powder in a layer by layer fashion using high energy electrons. Due to the directional solidification effects, the microstructure seen in this process consists of a columnar grain structure along the growth direction and an equiaxed structure at the cross-sectional growth plane. This type of structure is thought to contribute to the anisotropy of tensile properties discovered in previous research. Although, preferred orientation of the α laths may play a role as well. Heat treatments above the β transus are performed in order to improve the tensile properties, specifically ductility, with intensions to remove preferred orientation and to disunite the columnar grain structure. Tensile testing, fractography, optical microscopy, and x-ray diffraction are used to characterize and compare the as-processed and β heat treated electron beam melted specimens. It is found for all β treated conditions, the ductility increases compared to the as-processed specimens, although the strength decreases. The mode of fracture changes from ductile dimple rupture in the asprocessed condition to transgranular cleavage with ductile dimple rupture for the heat treated specimens. The macrostructure and microstructure in the as-processed and heat treated specimens contrasted greatly. The macrostructure changes from a fully columnar structure to a mixture of columnar and equiaxed grains. A fine acicular microstructure is observed in the as-processed samples, whereas a broad lamellar colony microstructure is formed during heat treatment. The presence of a colony microstructure is a possible reason for the improvement in ductility. From the x-ray data obtained, the preferred orientation is not reduced but instead increases after heat treating in the β region which likely is a result of the favorable rearrangement of slip systems due to the change in α lath orientation.

Full textAbstract:
Some agri-food managers of United States-based companies use strategies to mitigate product-harm crises.The loss of brand and corporate sustainability increases for companies not utilizing mitigating strategies to reduce losses from agri-food product-harm crisis.The purpose of this multiple case study was to explore the strategies managers use to mitigate losses from agri-food product-harm crises. Coombs' situational crisis communication theory served as the conceptual framework for this study. A sample of 3 managers from 3 agri-food companies in the southern United States shared their mitigating strategies to reduce losses from a product-harm crisis. Methodological triangulation assisted in reviewing and analyzing information from semistructured interviews, relevant company documents, and journal notes. The use of alphanumeric coding, discovering, and identifying themes, selecting relevant themes, organizing themes in hierarchical order, and linking themes to the phenomenon under study indicated four main themes supporting the benefits of mitigating strategies to reduce losses from an agri-food product-harm crisis. The main themes included the use of pre-crisis mitigating strategies, mid-crisis mitigating strategies, post-crisis mitigating strategies, and high pressure pasteurization (HPP). Findings from this study indicated that agri-food managers use strategies to mitigate product-harm crises, but the added expense of some mitigating strategies often precludes their use. The study findings may contribute to social change by increasing the awareness of agri-food managers, consumers, and company leadership to use mitigating strategies to reduce the number of illnesses and deaths associated with a product harm crisis.

Full textAbstract:
Raw vegetables can sometimes be the source of outbreaks of human illness; however the potential for fresh vegetables to serve as a vehicle for antibiotic -resistant bacteria is poorly understood. Antibiotics and antibiotic-resistant bacteria have been shown to persist in manure of animals administered antibiotics, and in compost generated from this manure, where there is the potential for their transfer to produce. The purpose of this study was to determine the survival of antibiotic-resistant bacteria on raw, peeled, carrots after washing with commonly used chemical sanitizers. Multi-drug resistant E. coli O157:H7 and Pseudomonas aeruginosa were inoculated into a compost slurry of composted manure from dairy cattle, with and without prior administration of antibiotics, and used to inoculate carrot surfaces prior to the washing studies. This approach provided defined model antibiotic-resistant pathogens present within a background microbial community simulating potential carry over from manure-derived fertilizer. Carrots (n=3, 25g) were air-dried and stored at 4 °C until washing with tap water, XY-12 (sodium hypochlorite, 50 ppm free chlorine) or Tsunami 100 (peroxyacetic acid/hydrogen peroxide, 40 ppm free paracetic acid), according to manufacturer's directions. A second batch of carrots representing each inoculation x wash condition (n=3) were individually packaged for storage at 2 °C for 1,7, and 14 days, or 10 °C for 7 days and enumerated on those day intervals to recover bacteria from the surfaces of washed carrots. The resulting previously washed and stored carrots were subject to serial dilution and plated onto corresponding agar to enumerate total aerobic bacteria (R2A), aerobic bacteria tolerant or resistant to antibiotics (antibiotic-supplemented R2A), E. coli (Eosin Methylene Blue), and Pseudomonas spp. (Pseudomonas Isolation Agar). In addition, the tetA gene was quantified from the carrot samples as a measure of the effect of sanitizers and storage on an antibiotic resistance gene known to be carried by the inoculated bacteria.Inclusion of sanitizer in the wash water significantly reduced the absolute numbers of inoculated bacteria (E.coli and Pseudomonas) as well as populations of bacteria capable of growth on the R2A media containing cefotaxime (10μg/mL), sulfamethoxazole (100μg/mL), or tetracycline (3μg/mL). Comparable reductions in the inoculated P. aeruginosa resistant to tetracycline (PIA T, 4μg/mL), bacteria resistant to cefotaxime (10μg/mL) and tetracycline (3μg/mL) occurred after washing with XY-12 or Tsunami 100. The sanitizer effectiveness may be bacterial dependent, as evident by larger absolute reductions of the inoculated E. coli (EMB) and bacteria grown on sulfamethoxazole (100μg/mL)-amended plates after washing with Tsunami 100 compared to washing with tap water or XY-12. Re-growth of both the inoculated and native compost-associated bacteria was inhibited by storage at 2 °C, as there were no significant differences in the log CFU/g values on the various media (total aerobic bacteria, bacteria on antibiotic-amended plates, E. coli inoculum, P. aeruginosa inoculum) during the 14-day storage period. However, temperature abuse at 10 °C resulted in significant re-growth of native Pseudomonas, compared to storage at 2 °C. A sanitizer-associated interaction between re-growth and temperature was also observed for bacteria resistant to clindamycin (25μg/mL) and cefotaxime (10μg/mL), with substantial re-growth occurring only on carrots washed with Tsunami 100. There was no significant re-growth of the inoculated E. coli O157:H7 at either temperature. Results indicate that some bacterial populations are reduced by post-harvest washes and that temperature abuse of fresh produce may result in increases in antibiotic-resistant bacterial populations.Master of Science in Life Sciences

Full textAbstract:
In the recent years, crowdfunding (a phenomenon where individuals collectively contribute money to back different goals and projects through the internet) has been gaining a lot of attention especially for its socio-economic impact. This dissertation explores this phenomenon in three distinct but related essays. The first essay explores the nature and dynamics of backers’ contributions and uses the insights generated to develop a forecasting model that can predict crowdfunding campaign outcomes. The second essay investigates how creators’ crowdfunding campaign design decisions impact their funding and post-funding outcomes. Interestingly, the essay highlights that certain crowdfunding campaign design decisions have differential effects on both funding and post-funding phases and this has implications for creators, backers, and crowdfunding platform owners. Finally, the third essay investigates whether creators’ post-funding relations-building efforts with backers matter and how such relations-building efforts might impact the performance of their subsequent crowdfunding campaign. In general, this dissertation not only increases our understanding of the crowdfunding phenomenon across the funding and post-funding phases, it also provides insights and tools that can help stakeholders maximize the benefits accruable to them when they engage in crowdfunding.

Full textAbstract:
The Women's Revolution in 2015 has led to a drastic shift in the ways women are portrayed in professional wrestling. The Women's Revolution came as a result of the social unrest over the lack of time women were receiving on the televised shows. Where women's storylines had centered on their sexuality, they are now presented as equal to their male counterparts after the Women's Revolution. Through an exploration of concepts in globalization, commodification, and socially produced spaces, this research seeks to understand and contextualize the Women's Revolution, the degree to which the portrayed women's equality has been achieved, and the resulting impacts of the female superstars overall. I argue that that this "equality" has been achieved through inscribing the traditionally masculine qualities of wrestling to women, has resulted in an unequal distribution of opportunities to particular female superstars rather than equality for all women on the shows, and that phallocentric objectification of the female superstars still occurs in certain aspects of professional wrestling.

Thesis (MBA (Business Management))--University of Stellenbosch, 2009.ENGLISH ABSTRACT: This research report is a comparative analysis of the pre-1996 marketing control board system and the post-1996 free market system in the fruit and vegetable industry in South Africa. The report investigates and discusses the advantages and disadvantages of both systems and their effect on the stakeholders of the industry. The control boards had both positive and negative effects on the producer within the fruit and vegetable industry. The free market system is currently also having an effect, both positive and negative, on the producer. In this research report these divergent effects are explored, the objective being to obtain a better understanding of their impact on the industry stakeholders. On reaching a clearer understanding, strategy recommendations have been designed and are presented for all producers operating within the fruit and vegetable industry. The fresh produce industry is large, with many stakeholders. The information potentially available is vast, but, given the fact that time was too limited to do a complete research study on the entire industry, it was decided to focus on four sectors of the industry, namely bananas, deciduous fruit, citrus and potatoes. To give the report more credibility in terms of the data acquired, a number of interviews were conducted with producers and producer organisation leaders, from whom first-hand, ground level information was obtained. In this research it was found, among other things, that in general there was an imbalance in both the producer and consumer surplus in South Africa. Despite regulation, the marketing control boards had, through the pooling of prices, provided benefits only to certain producers. This, in effect, meant that quality improvement was largely negated, as the return to the producer did not provide an incentive to produce a better quality product. Contrary to the control board system, the free market system provides industry stakeholders with many opportunities, while the role of producers is also evolving to incorporate aspects of marketing. Producers consider service excellence, and culture and diversity to be important. Furthermore, in terms of available channels for marketing, many producers view the fresh produce markets as a desirable means of marketing their produce, as these outlets are still considered to be the price-determining mechanism for the fresh produce industry.
AFRIKAANSE OPSOMMING: Hierdie navorsingsverslag is 'n vergelykende studie van die bemarkingsbeheerraadstelsel voor 1996 en die vryemarkstelsel ná 1996 in die vrugte- en groentebedryf in Suid-Afrika. Die verslag ondersoek en bespreek die voor- en nadele van albei stelsels en hul uitwerking op die bedryf se belangegroepe. Die beheerrade het ’n positiewe sowel as negatiewe uitwerking op die produsent in die vrugte- en groentebedryf gehad. Die vryemarkstelsel het tans ook ’n positiewe sowel as negatiewe uitwerking op die produsent. Hierdie uiteenlopende gevolge word in hierdie navorsingsverslag verken om só ’n beter begrip van die impak daarvan op die bedryf se belanghebbers te verkry. Strategie-aanbevelings is op grond van groter begrip ontwerp en aan produsente in die vrugte- en groentebedryf voorgelê. Varsprodukte is die grootste bedryf in vrugte- en groentebedryf, en daar is talle belangegroepe. Die inligtingsmoontlikhede is enorm, maar gegewe die feit dat tyd te beperk was om ’n volledige navorsingstudie van die hele bedryf te onderneem, is daar besluit om vier sektore te beklemtoon, naamlik piesangs, sagtevrugte, sitrus en aartappels. Om die verslag meer geloofwaardigheid te gee ten opsigte van die data wat verkry is, is ’n aantal onderhoude met produsente en die leiers van produsentorganisasies gevoer om eerstehandse, voetsoolvlakinligting te bekom. Die verslag het onder meer bevind dat daar oor die algemeen ’n wanbalans in die produsente- sowel as verbruikersurplus in Suid-Afrika is. Die bemarkingsbeheerrade het ondanks regulasie voordele slegs aan sekere produsente gebied deur die saampot van pryse. Dit het in werklikheid beteken dat gehalteverbetering grootliks ontken is omdat die opbrengs nie die produsent aangespoor het om die gehalte van hul produkte te verbeter nie. Die vryemarkstelsel bied, in teenstelling met die beheerraadstelsel, talle geleenthede aan die bedryf se belangegroepe terwyl die rol van produsente ook ontwikkel word om aspekte van bemarking te inkorporeer. Produsente beskou voortreflike diens, en kultuur en diversiteit as belangrik. Daarby beskou produsente die varsproduktemark, wat een van die beskikbare bemarkingskanale is, as ’n wenslike manier om hul produkte te bemark omdat dié afsetpunt steeds as die prysbepalende meganisme vir die varsproduktebedryf gesien word.

Full textAbstract:
Hemophilia B is a debilitating and life-threatening disorder caused by a deficiency in or dysfunction of factor IX (FIX), a complex plasma glycoprotein required for the formation and maintenance of blood clots. Treatment of hemophilia B involves infusion of replacement FIX currently derived from two sources: FIX purified from pools of human plasma (pd-FIX) and a single recombinant FIX product generated in genetically engineered Chinese hamster ovary (CHO) cells. Both of these FIX products are prohibitively expensive, limiting of the treatment options of hemophiliacs worldwide. As a result, a more abundant and affordable FIX product would greatly improve the life prospects for hemophiliacs.
The biological activity of FIX is dependent upon its numerous post-translational modifications (PTMs), including gamma-carboxylation, proteolytic maturation, phosphorylation, sulfation, and glycosylation. Of these PTMs, those known to be vital for activity are gamma-carboxylation of multiple glutamate residues near the N-terminus and proteolytic cleavage of the FIX propeptide. When expressed at a high rate in exogenous expression systems, however, the ability of current systems to effect the necessary PTMs is severely rate limited, restricting the production of active FIX.
The transgenic pig bioreactor represents a promising source for the production of large quantities biologically active FIX due to its demonstrated ability to perform the required FIX PTMs. It was the goal of this study to characterize the PTM structure and the resulting function of recombinant FIX when expressed at 1-3 mg/ml in the transgenic pig mammary epithelium (tg-FIX). It was found that the expressed tg-FIX is comprised of a heterogeneous mixture of FIX PTM isoforms. This mixture represents a spectrum of tg-FIX molecules of varying gamma-carboxyglutamic acid (Gla) and propeptide content, indicating that rate limitations in effecting these PTMs are present. A purification process was developed utilizing heparin-affinity chromatography to purify the total population of tg-FIX from pig milk, a complex multi-phase feedstock. Subsequently, a process was developed to fractionate the total population of tg-FIX into subpopulations based upon the extent of post-translational modification. Q ion-exchange chromatography was utilized to fractionate tg-FIX based upon molecular acidity which was found to be correlated to both biological activity and Gla content. The resulting biologically active tg-FIX population contained an average of 7 of the 12 Gla residues found in pd-FIX. Immuno-affinity chromatography was subsequently utilized to further fractionate tg-FIX into mature tg-FIX and propeptide-containing tg-FIX populations.
The isolated FIX PTM populations were subjected to functional analysis by investigating in vitro clotting activity, activation by factor XIa, and in vivo pharmacokinetics. From this analysis it was found that mature tg-FIX with an average 7 Gla residues, representing approximately 9% of the total tg-FIX produced, exhibits wild-type in vitro clotting activity and normal activation by factor XIa. The remainder of the tg-FIX produced, characterized by either a lower Gla content or the presence of the propeptide, was found to be inactive and displayed less efficient activation by factor IXa. In an in vivo pharmacokinetic study in the hemophilia B mouse model, biologically active tg-FIX was found to possess altered circulating properties. Tg-FIX was characterized by a lower recovery, approximately one-sixth that of pd-FIX, but an extended circulation half-life. From this study it was found that the mean residence time of tg-FIX after injections is approximately twice that observed for pd-FIX. These altered pharmacokinetic properties are likely linked to the unique tg-FIX PTM structure, perhaps through altered endothelial cell binding characteristics caused by the reduced Gla content.Ph.

Förhoppningen är att denna fallstudie ska fungera som ett komplement till rådande studier inom glokalisering. Teori: Uppsatsens teoretiska referensram består av erkända koncept inom marknadsföringsområdet såsom global branding, glokalisering och produktlivscykeln men även Hofstedes kulturella dimensioner. Metod: En kvalitativ fallstudie för det multinationella företaget 3Ms varumärke Post- it har utförts. Primärdata har samlats in genom ostrukturerade och semi-strukturerade djupintervjuer med personer med marknadsansvar över Post-it samt genom en dokumentstudie. Analysen har skett med ett analysverktyg skapat utifrån de teoretiska utgångspunkterna. Resultat: De lokala marknadsförarna för varumärket Post-it är relativt fria i branding- arbetet och lokala anpassningar förekommer i allra högsta grad. Standardisering förekommer också i form av bl.a. gemensamma kampanjer och hemsidor. Glokalisering är implementerat i Post-its varumärkesstrategier. Slutsats: Branding-arbetet anpassas relativt mycket lokalt i Norden och frihetsgraden är stor. Hofstedes dimensioner och produktlivscykeln kan till viss del förklara varför det empiriska resultatet som framkommit ser ut som det gör.

Full textAbstract:
Background: The expansion of e-commerce and online orders have led to companies creating new marketing strategies, where impulsive purchases are important in order to boost sales. However, this also has negative aspects concerning overconsumption and the environmental impact. Consumers are more likely to have negative post-purchase emotions when making an impulsive purchase, and thus are more prone to return products. This research aims at creating a deeper understanding about consumers’ post-purchase emotions after making an impulsive purchase and how a product return affects the post-purchase emotions. Problem discussion: Impulsive buying is critical for online stores and retailers are actively trying to increase these purchases for all customers, but at the same time, there is a growing number of product returns. This makes it important for firms to understand how consumers think and react to an impulsive purchase, since this supposedly has an impact on product returns. By providing a deeper understanding regarding the consumer’s post-purchase emotions one can specify such reactions on shoppers and help future marketing activities preventing consumers’ negative emotions in the purpose of increasing organizational profitability and decreasing the environmental impact. Purpose: The purpose of this research is to build a theory that will provide organizations with knowledge about the chosen segment of Swedish women in the age 18-35 post-purchase emotions after impulsive buying. The findings of this study can contribute with additional insights to previous theoretical knowledge about post-purchase emotions after impulsive shopping. Method: This qualitative research has been conducted by using 14 semi-structured interviews with the chosen segment of Swedish females in the age 18-35 who had previously shopped impulsively online and returned products. For the data analysis, an interpretative phenomenological analysis was used, providing the research with reflections regarding the perspective of the participants’ experiences of impulsive shopping and their post-purchase emotions. Results: This research indicates that the participants generally held a negative view of impulsive buying, where they reduced/strengthened their post-purchase emotions through three rationalizations which were named by the authors “Social Proof”, “Use-Principle” and “Limited Funds”. When making a product return, the participants either had strengthened emotions or the negative emotions were turned into positive emotions. This was connected to three themes found by the authors which were called “Income”, “Return Policy”, and “Social and Environment”. The analyzed findings were presented in a developed framework.

Les logiciels défectueux ont des conséquences coûteuses. Les développeurs de logiciels doivent identifier et réparer les composants défectueux dans leurs logiciels avant de les publier. De même, les utilisateurs doivent évaluer la qualité du logiciel avant son adoption. Cependant, la nature abstraite et les multiples dimensions de la qualité des logiciels entravent les organisations de mesurer leur qualités. Les métriques de qualité logicielle peuvent être utilisées comme proxies de la qualité du logiciel. Cependant, il est nécessaire de disposer d'une métrique de processus logiciel spécifique qui peut garantir des performances de prédiction de défaut meilleures et cohérentes, et cela dans de différents contextes. Cette recherche avait pour objectif de déterminer un prédicteur de défauts logiciels qui présente la meilleure performance de prédiction, nécessite moins d'efforts pour la détection et a un coût minimum de mauvaise classification des composants défectueux. En outre, l'étude inclut une analyse de l'effet de la combinaison de prédicteurs sur la performance d'un modèles de prédiction de défauts logiciels. Les données expérimentales proviennent de quatre projets OSS. La régression logistique et la régression linéaire ont été utilisées pour prédire les défauts. Les métriques Change Burst ont enregistré les valeurs les plus élevées pour les mesures de performance numérique, avaient les probabilités de détection de défaut les plus élevées et le plus faible coût de mauvaise classification des composantsFaulty software have expensive consequences. To mitigate these consequences, software developers have to identify and fix faulty software components before releasing their products. Similarly, users have to gauge the delivered quality of software before adopting it. However, the abstract nature and multiple dimensions of software quality impede organizations from measuring software quality. Software quality metrics can be used as proxies of software quality. There is need for a software process metric that can guarantee consistent superior fault prediction performances across different contexts. This research sought to determine a predictor for software faults that exhibits the best prediction performance, requires least effort to detect software faults, and has a minimum cost of misclassifying components. It also investigated the effect of combining predictors on performance of software fault prediction models. Experimental data was derived from four OSS projects. Logistic Regression was used to predict bug status while Linear Regression was used to predict number of bugs per file. Models built with Change Burst metrics registered overall better performance relative to those built with Change, Code Churn, Developer Networks and Source Code software metrics. Change Burst metrics recorded the highest values for numerical performance measures, exhibited the highest fault detection probabilities and had the least cost of mis-classification of components. The study found out that Change Burst metrics could effectively predict software faults

The mango tree is one the important sources of income in the rural economy of Senegal. However, mango producers in Ziguinchor are facing fruit fly infestations leading to important losses in income. The aim of this study is to measure the impact of the losses encountered by mango farmers in Ziguinchor over three years 2012, 2013, and 2014 and conduct an econometric study to examine household characteristics associated with high level of losses. At the household level, the total yearly losses on average from fruit fly infestations represent 17.09 % of the average total household income in Ziguinchor (Casamance). The losses associated with variability of production are much smaller than losses from decreases of average yield. Furthermore, the results show that the number of hectares, level production, and use of Keitt varieties are three factors statistically significant, with a significant positive influence on losses from infestation. The use of fruit fly control technologies does not appear to significantly reduce losses.Master of Science

The rapid disposal of products has detrimental effects on environment which is increasing resource consumption for the production of new products, along with the waste production. Therefore, designing long lasting products has great importance for achieving sustainable consumption and production. The present study analyzes the implications of an approach called post-use design thinking for achieving sustainable consumption and production through product longevity. To explore that approach, two educational industrial design projects are analyzed throughout the study. The results suggest that post-use design thinking should be considered at the early stages of the design process. The idea generation exercises developed specifically for this design thinking seem to be helpful in generating design solutions for post-use phase. The results also indicate that the post-use design thinking is feasible in terms of design and production for glass packaging products, which is the specific case analyzed throughout the research.

Full textAbstract:
This study investigated the manufacturing procedures and texture attributes of direct acid set of an unripened, shelf-stable cheese variety produced by the combined technologies of ultrafiltration and ultra-high temperature processing. Product evaluation included physical and chemical properties such as gel strength, syneresis, pH, moisture, protein, and fat. Whole milk was concentrated by ultrafiltration to 30, 35, and 40% total solids. Milk retentate was ultra-high temperature-processed by preheating to 65 or 77°C, sterilized at 141°C for 4 s by direct steam injection, flash cooled to approximately 62 or 72°C, homogenized in two stages at either 13.8/2.1 or 27.6/4.1 MPa, cooled to 38°C, and aseptically packaged. iv sterilized sodium chloride was aseptically added and dissolved in the ultra-filtrated and ultra-high temperature processed retentate to produce .5% final concentration. Autoclaved solutions of citric and lactic acids, or glucono-delta-lactone were added aseptically to the salted retentate to form a soft gel by lowering the pH range from 4.3 to 4.6. The coagulated retentates were stored at room temperature for 6 months. The effects of total solids, homogenization pressures, preheat temperatures, acidulants, and storage time on selected physicochemical properties of the acid gels were determined.
Taste panels evaluated selected soft cheese characteristics after 6 months' storage. No statistically significant effect of the total milk solids level on gel firmness was observed. High homogenization pressure and the interaction of high preheat temperature and homogenization pressure produced significantly firmer gel and caused less syneresis. Acidulant types influenced significantly gel strength, syneresis, appearance, and texture. Soft cheeses prepared with citric acid were firmer than those acidified with lactic acid or gluconodelta-lactone. Lactic acid samples produced more syneresis than citric acid cheese samples. Cheese samples prepared with glucono-delta-lactone had the smoothest and least grainy texture, shiny appearance, little or no wheying-off, and a gel strength intermediate between the two other acidulants.

This dissertation chronicles the development of a series of plays, collectively referred to as The Arab Shakespeare Trilogy, from the perspective of their playwright Sulayman Al-Bassam. Together, The Al-Hamlet Summit (2002-2005), Richard III, An Arab Tragedy (2007-2009), and The Speaker's Progress (2011-2012) register the eruptive social, political, and cultural contexts of the Arab world during the first decade of the twenty-first century while negotiating the adaptation of Shakespeare's plays to a form thought-provoking and entertaining to audiences both within and outside the Middle East. The document outlines the inception of the project, which includes both personal and historical context, and provides more specific commentary on the production of each play individually. In addition to its focus on the specific impact of 9/11, and its global consequences, on the development of these dramatic works, it attends to topics including the technical and ideological challenges of linguistic and cultural translation, the adaptation of Shakespeare in Arabic theatre, the politics of art and drama in the Arab world, and the involvement of art in the shaping of the ethics of cross-cultural representation. Of particular interest are the linguistic conditions bearing upon the adaptation of English language texts into multi-lingual and cross- cultural works, the effects of the globalisation of politics and media, and the international touring life of the plays between the Arab region and wider world. The play texts of the Trilogy make up the second part of the document. The methodology of this dissertation deploys historical contextualisation, autobiographical memoir, literary analysis and creative improvisation. The play-texts are dramatic adaptations of specific Shakespeare texts to the Arab world.

Em um mundo marcado pela globalização, mercados comuns, grandes grupos corporativos, produção em massa e uma oferta quase ilimitada de produtos industriais, a individualização é um requisito que ganha cada vez mais importância entre os consumidores. O mercado para produtos que expressem sua personalidade e seus gostos, que os identifiquem e os tornem únicos por meio da customização, está em franca expansão. Isto abre uma possibilidade para o design comprometido em desenvolver produtos que atendam essas necessidades individuais, mesmo em produtos produzidos em massa. No entanto, os métodos projetuais usualmente empregados por profissionais do design não contemplam esse novo cenário, gerando uma lacuna a ser estudada. Este trabalho tem como objetivo, identificar etapas e características dos processos metodológicos que incorporam a customização pós-produção. Este trabalho faz uso da investigação exploratória, bibliográfica e qualitativa por meio da aplicação de questionários e entrevistas. A aplicação das entrevistas ocorreu com um grupo de profissionais atuantes nas diferentes áreas do design de produto. A síntese das entrevistas, aliada a uma análise comparativa dos dados convergentes e divergentes, somaram para identificação das principais etapas no desenvolvimento de produtos que levam em conta a customização do usuário pós-produção. Os resultados finais dão conta da importância do pensamento voltado para a customização em diversas etapas do processo de projeto em design.In a world marked by globalization, common markets, large corporations, mass production and an almost unlimited supply of industrial products, individualization is a requirement that is increasingly gaining importance among consumers. The market for products that express your personality and tastes, identifying them and make them unique by customizing is booming.

However, projective methods usually employed by design professionals do not consider this new scenario, creating a gap to be studied. This study aims to identify steps and characteristics of methodological processes that incorporate the customization postproduction. This work makes use of exploratory research, and qualitative literature through questionnaires and interviews. The application of the interviews took place with a group of professionals working in different areas of product design. A summary of the interviews, together with a comparative analysis of convergent and divergent data, amounted to identify key steps in developing products that take into account user customization postproduction. Final results realize the importance of thought toward customization in various stages of project design.

The mobilisations of those techniques led to the rise of productivity of genomic centers as a dominant norm in this field. Functional genomics appeared in a second time, based on the use of technologies like DNA arrays.

Full textAbstract:
The retailing industry is battling a behemoth – the escalating problem of product returns. The problem is of a graver import for e-tailers. However, the underlying cognitive and affective appraisal process that leads to product returns in case of online purchase still remains unclear. The liberal product returns environment in the context of online purchase has led consumers to proactively consider the option of decision reversal. Nevertheless, the impact of the initial buying context on the post-purchase appraisal process has been neglected in previous studies. To bridge the gaps found after evaluating the current gamut of research work conducted on this topic, a mixed-method approach was employed in the present study. Using in-depth semi-structured interviews (N = 42), the first qualitative study identified three online purchase situations (unplanned, purchase-for-trial and opportunism buying) that frequently provoke product returns. Additionally, the qualitative uncovered the salient post-purchase appraisal factors. To empirically test the underlying appraisal process and the differences caused by the buying situations, a quantitative study was conducted, using scenario-based experiment (N = 620). Findings suggest that contrary to recent studies (e.g., Lee, 2015; Powers & Jack, 2013), cognitive dissonance is not the immediate cause of product returns. It is the affective factor, regret, which leads to decision reversal. Additionally, in opposition to the claim of previous literature that high coping potential reduces stress, this study suggests that the ability to reverse the decision actually increases regret and, in turn, leads to product returns. Results also indicate that buying context (e.g., different buying situations) causes difference in serial mediation pathways from both primary and secondary appraisal to product returns likelihood. E-tailers should utilise consumers’ behavioural profile in order to classify different consumer groups and tailor the means to manage product returns accordingly.

Full textAbstract:
The focus of this study was to analyze whether the psychostimulant nicotine would enhance reference and working memory consolidation in rats tested on the 8-arm radial arm maze. Mecamylamine, a nicotine antagonist, was used to attempt to block the enhancement of memory consolidation. All rats were given one training trial/day for 12 consecutive days, and 4 arms were baited. Rats were separated into five groups: the saline-nicotine group received an intraperitoneal (i.p.) injection of saline immediately after each trial followed 15 min later by an subcutaneous (s.c.) injection of nicotine (0.6 mg/kg free base); the nicotine-delay group received an s.c. injection of nicotine 2 h after each training trial, two groups received an i. p. injection of one of two different doses of mecamylamine (2.5 and 6.0 mg/kg) immediately after each trial, which was followed 15 min later by an s.c. nicotine injection, and a control group received an i.p. injection of saline immediately and 15 min after each training trial. Results showed that the saline-nicotine group made fewer reference and working memory errors than the saline- or nicotine-delay groups, but only the effect of nicotine on reference memory was blocked by the higher dose of mecamylamine. It appears from these results that nicotine's effects on reference and working memory may be mediated through different mechanisms.

Full textAbstract:
In an intensely competitive retail market, keeping consumers satisfied has never been more important than currently. Retailers need to understand how to satisfy their customers in order to enhance their appeal and increase consumer loyalty. Globally people’s lifestyles are changing rapidly. Advances in technology, more flexi-time of customers, and the many other social and economic changes affecting family and home life are some of the reasons why, specifically in the Fast Moving Consumer Goods (FMCG) industry, it is important to act fast to service customers. In South Africa, there is indication of strong competition between the most dominant firms’ in the FMCG market, which include Pick ‘n Pay Holdings Limited (23.8 percent), Shoprite Holdings Limited (23.8 percent), the Spar Group Limited (14.9 percent), and Woolworths Holdings Limited (9.0 percent). As a result, it is unmistakable that in order for FMCG firms to grow and survive in the constantly changing, and competitive retail environment of South Africa, they must have a clear understanding of consumer’s expectations, as well as their actual shopping experiences. As stated, service quality for retailers of FMCG is of utmost importance to their level of success and ability to successfully cater for the market’s needs. Closely linked to this, is the focus of this study, namely to investigate consumers’ perceived levels of product quality, as well as the overall level of satisfaction experienced by customers. The purpose of this analytical research project is twofold: Firstly, to empirically test the hypothetical model and the associated hypotheses (as phrased in Section 1.4) by using confirmatory statistical techniques. Secondly, based on the findings of the research, to craft appropriate retail marketing strategies within the FMCG market that are suitable for implementation to address potential mismatches (gaps) of perceived product quality and consumers’ satisfaction. By the crafting of appropriate retail strategies, the potential to develop the FMCG industry in South Africa will be enhanced. Given the purpose and nature of the research in question, a positivistic research paradigm was adopted. The utilization of a Likert seven-point scale enabled primary data to be sourced from 301 consumers’ (respondents), who shared their perceptions on the expectations and actual experiences about the product quality of FMCG in South Africa. The statistical analysis of quantitative data comprised seven distinct phases. Firstly, the data was subjected to a confirmatory factor analysis to validate the measurement model by assessing the construct (convergent, discriminant and nomological) validity of the pre-specified (predicted) factors. Secondly, the reliability (internal consistency) of the research instrument was assessed by means of Cronbach alpha reliability coefficients. This phase was followed by a multiple linear regression analyses which were used to test the impact of independent variables on the intervening variable. In order to test the second set of hypotheses (null and alternative hypotheses dealing with consumers’ expected product quality and their actual experiences) matched paired t-tests were utilized. Additionally, mean scores and relative percentage ratings on consumers’ expected and perceived product quality levels were also calculated and interpreted. Finally, bivariate linear regression analyses were used to test the third set of hypotheses (impact of consumers perceived product quality on consumers overall level of satisfaction). The findings of the multiple linear regression analyses required that the hypothetical model be reconstructed. Two variables were removed from the hypothetical model, namely, ‘South African culture’ and ‘service promises’. The findings of the matched pair t-tests show that significant statistical differences do exist between the ‘expectations’ and ‘actual experiences’ of consumers’ perceived product quality to support the hypothesis H3.A, namely: “There are no perceived differences between consumers’ expectations and their perceptions (actual experience) of product quality”. Besides the matched pair t-tests, further descriptive statistical analyses were also performed to assess the magnitude of the “gap” between expectations and actual experiences of consumers on South African FMCG product quality, such as the values for Cohen’s d and relative percentage ratings. The findings reveal that the consumers’ were not completely satisfied with their actual experiences. Three sets of conclusions and recommendations were identified for this research. Firstly, conclusions emanating from secondary sources on product quality and consumers’ satisfaction literature were provided, such as consumer satisfaction is seen more as a psychological state, which reveals an overall feeling of consumers’ purchase and consumption experience with FMCG. Secondly, the conclusions linked to the interpretation of the empirical findings revealed significant statistical differences between the expectations and perceptions (actual experiences) of consumers’ on perceived product quality. Finally, recommendations on relevant FMCG retail marketing strategies can be grouped into five domains: To build customer-led firms which adhere to the principles of true marketing orientation where the focus is on consumers and their needs and wants. Identify and clearly define the FMCG market in South Africa which comprises different market segments that are of great importance for the retail firms. The decision on a proper positioning strategy entails the choice of the target market segments, which will determine where and how the FMCG firm competes and the choice of differential advantages. Retailers should apply suitable marketing strategies to benefit optimally from their FMCG retail marketing strategies. A sound feedback system is a necessary component in the strategic marketing plan to obtain proper feedback that would contribute to the “management by exception” principle. It further will facilitate performance evaluation of product quality and service delivery, as well as and enable corrective actions to be taken in the case of deviations from the norm.

Full textAbstract:
Dimension herbicide (dithiopyr) was applied to common bermudagrass turf at 90, 60, and 45 days before fall overseeding to measure the efficacy for turf safety and for control of fall germinating POA Annua (PA). Applications were made at 0.25, 0.375, and 0.50 lbs. AI/A on each date. One half of each plot was overseeded, while the other half was not. Percent plot (PA) infestation and percent weed control was more greatly affected by the process of overseeding, than that of the herbicide applications alone. When not overseeded, the bermudagrass turf had a maximum of 45% PA control in November, which decreased dramatically to little or no control from January to March 2000. With the inclusion of ryegrass overseed, the high rate (0.50 lbs. AI/A) applied closest to the overseeding (45 DBOS) provided between 79-82% PA control over the length of the test. Actual infestation levels among non-chemical receiving control plots showed a 3X increased level in PA suppression due to overseeding, when compared to the non-overseeded, non-chemical controls. Dimension herbicide alone had little effect for PA control. When combined with overseeding, the 0.50 lb. AI/A rate, applied at 60 or 45 DBOS provided the greatest levels of PA control. The performance of Dimension on non-overseeded bermudagrass does not support the anticipated use of this chemical for PA control.

Full textAbstract:
The present study was firstly aimed at producing the AM fungal inocula by using soil-based and soil-less culture techniques, including the in-vitro axenic technique, and secondly to assess the infectivity and effectiveness of the inocula so produced in glasshouse and field conditions. Indigenous AM fungi from 5 different sites of New South Wales were successfully propagated and multiplied using the pot-culture and atomizing disc aeroponic culture techniques, and their infectivity was measured using the MPN bioassay method. The coarse and fine sand mix was proven to be very effective for the production of AM fungal inocula. The findings indicated that aeroponic culture technique is far superior to that of conventional pot-culture technique, and could possibly substitute the most commonly used pot-culture technique of AM fungal inoculum production. The ultra-sonic nebulizer technology could possibly be an alternative to conventional aeroponic systems for producing AM fungal isolates in commercial quantities. The introduction of the sheared-root inoculum of Glomus intraradices, produced by the ultra-sonic nebulizer technique, into agricultural soils can substantially reduce the intake of P-fertilizers as much as 50% of the recommended level. The study also indicated that soil phosphorus is a critical factor in limiting mycorrhizal colonization, possibly limiting mycorrhizal responses.The research suggests that various commercially produced single or 'cocktail' inocula may work on mycorrhiza dependent plants in soils where the indigenous AM flora is either not abundant and/or efficient. Furthermore, ecophysiology of the same AM species have different effects on plant growth.Doctor of Philosophy (PhD)

Information technology in mature organisations is viewed as an enabler of teams working together in the product development process. Technology is no longer pursued as an end in itself, but for its contribution to cost control, product quality, and most importantly, time to profit. The focus of this research is the analysis of methodologies used to implement the Teamcenter Engineering Product Data Management (PDM) system at Delta Motor Corporation, which manages all of Delta’s CAD data. The main problem of this research is as follows: How can Delta Motor Corporation successfully implement the “Teamcentre Engineering” Product Data Management System? The main problem will be broken down into three distinct parts, namely the developing of a best practice process, analysing Delta’s implementation and making recommendations for improvement. The literature survey provides the basis for developing a best-practice process, which serves as a benchmark against which to evaluate the methodology used by Delta. Interviews were conducted with selected personnel who were involved in the implementation, and Tesch’s model for content analysis used to analyse the responses. The implementation process of Teamcenter Engineering at Delta was conducted in three phases and only the first was completed at the time of writing this research paper. For this reason, analysis revolves around the first phase of implementation, which was limited to the drawing office, while recommendations are made for the implementation of phase two and three, which roll-out this system to the rest of Delta and it’s supplier base.

Full textAbstract:
In recent years, industrialised house building has gained shares on the Swedish house building market. The market demands for industrialised house building are exceeding the available supply of housing and experiencing a substantial increase in the housing production costs. For industrialised house building, the design has been identified as a critical phase with the systematization of the design a necessary part of industrialisation. Therefore, companies strive towards the inclusion of standardization and controlled processes in the design phase. Product platforms have proved to be related to the standardization of processes and products. Introducing a product platform approach in the design phase of house building could be a way to improve the design and ensure value creation in entire processes. Thus, the aim of this research is to outline means to support and improve the design phase of industrialised house building by using a product platform approach. A Swedish multi-storey house building company that uses glulam post and beam building system with a focus on platform development was used as the single case study in this research. The company intends to achieve increased efficiency by moving towards industrialized approaches. Empirical data were mainly gathered from interviews, observations, workshops, and document analysis. The findings present the existing challenges in the housing building industry and outlines twenty critical success factors that need to be considered in the design phase. Also, the result outlines support methods and tools that can be used for the improvement of the design phase when applying a product platform approach. Moreover, a flexible product platform can be developed with the support of parametric modelling and used to design building components having an engineer-to-order characteristic. Finally, the results show that a building system can be considered as part of a product platform in light of the necessity of an adequate support in the design process to maintain a sustainable platform. Thus, the contribution includes the addition of knowledge to platform theory in general and its application on the design phase of industrialised house building.Under de senaste åren har det industriella husbyggandet tagit andelar på den svenska husbyggnadsmarknaden. Behovet av bostäder på marknaden överstiger tillgången och med ökning av bostadsproduktionskostnaderna som konsekvens. För det industriella husbyggandet har projekteringen identifierats som en avgörande fas och dess systematisering är en nödvändig för industrialiseringen. Som en följd strävar företag i segmentet efter att inkludera standardisering och kontrollerade processer i projekteringen. Produktplattformar har kunnat kopplas till standardisering av processer och produkter. Införandet av produktplattformar i projekteringen kan vara ett sätt att förbättra designen och säkra värdeskapandet igenom hela processen. Således är syftet i denna avhandling att ta fram medel för att stödja och förbättra projekteringen för industriellt husbyggande genom att tillämpa en ansats med produktplattformar. Ett svenskt byggnadsföretag med flera våningar som använder limträ- och balksystem med fokus på plattformsutveckling användes som en enda fallstudie i denna forskning. En fallstudie har genomförts på ett företag som bygger flervåningshus med ett pelar-balksystem i limträ med fokus på plattformsutveckling. Företaget har ambitionen att nå högre effektivitet genom att röra sig mot ett mer industriellt tillvägagångssätt. Data samlades in från intervjuer, observationer, workshops och dokumentanalyser. Resultaten visar vilka de befintliga utmaningarna är för husbyggandet och presenterar tjugo kritiska framgångsfaktorer som ska beaktas i projekteringen. Studien har även tagit fram supportmetoder och verktyg som kan användas för att förbättra projekteringen vid tillämpning av produktplattformar. Vidare, en flexibel produktplattform kan utvecklas med stöd av parametrisk modellering och användas för att projektera byggnads-komponenter med engineer-to-orderegenskaper. Slutligen, resultaten pekar mot att ett byggsystem kan betraktas som en del av en produktplattform ur perspektivet att tillräckligt med stöd i projekteringen krävs för att underhålla en hållbar plattform. Således, arbetet har bidragit med kunskap till teori om plattformar i allmänhet och dess tillämpning på projekteringen för industriellt husbyggande.

Full textAbstract:
Background: A sustainable economy becomes more and more important for most parts of the society. Especially the fashion industry is being criticized for wasting resources and being non-sustainable. Therefore, some textile producers started to implement programs that are aiming on a reuse of garments. Aims of research: The purpose of this research is to discover how customers can be motivated to return unwanted garments, also considering possible hindering factors. To gather this information it is necessary to build a theoretical framework with customer-based theories. The thesis explored how a second hand multi-brand retailer can take active action in encouraging customers to return unwanted textiles. Method: This research was conducted as an inductive qualitative research. The data was gathered through semi-structured interviews with several second hand retailers. The analysis was carried out following the Giogia method. Results: The thesis revealed that the garment disposal behavior is affected by various influences. Influences on the disposal behavior of garment consumers are personal values and believes. The dispose of unwanted garments is often influenced by an ease of handling and the same behavior is followed over the years simply because individuals are used to a certain garment disposal behavior. The largest hindering factors why customers do not return garments to retailers are caused by a lack of information as well as insufficient transparency. This behavior can be affected by second hand retailers by providing improved communication and a motivation to return garments by offering benefits for the customer. The size of the company does not play a major role.

Full textAbstract:
Cette thèse aborde le problème de la décomposition booléenne des tableaux multidimensionnels de données binaires par modèle de mélange post non-linéaire. Dans la première partie, nous introduisons une nouvelle approche pour la factorisation booléenne en matrices binaires (FBMB) fondée sur un modèle de mélange post non-linéaire. Contrairement aux autres méthodes de factorisation de matrices binaires existantes, fondées sur le produit matriciel classique, le modèle proposé est équivalent au modèle booléen de factorisation matricielle lorsque les entrées des facteurs sont exactement binaires et donne des résultats plus interprétables dans le cas de sources binaires corrélées, et des rangs d'approximation matricielle plus faibles. Une condition nécessaire et suffisante d'unicité pour la FBMB est également fournie. Deux algorithmes s'appuyant sur une mise à jour multiplicative sont proposés et illustrés dans des simulations numériques ainsi que sur un jeu de données réelles. La généralisation de cette approche au cas de tableaux multidimensionnels (tenseurs) binaires conduit à la factorisation booléenne de tenseurs binaires (FBTB). La démonstration de la condition nécessaire et suffisante d’unicité de la décomposition booléenne de tenseurs binaires repose sur la notion d'indépendance booléenne d'une famille de vecteurs. L'algorithme multiplicatif fondé sur le modèle de mélange post non-linéaire est étendu au cas multidimensionnel. Nous proposons également un nouvel algorithme, plus efficace, s'appuyant sur une stratégie de type AO-ADMM (Alternating Optimization -ADMM). Ces algorithmes sont comparés à ceux de l'état de l'art sur des données simulées et sur un jeu de données réellesThis work is dedicated to the study of boolean decompositions of binary multidimensional arrays using a post nonlinear mixture model. In the first part, we introduce a new approach for the boolean factorization of binary matrices (BFBM) based on a post nonlinear mixture model. Unlike the existing binary matrix factorization methods, the proposed method is equivalent to the boolean factorization model when the matrices are strictly binary and give thus more interpretable results in the case of correlated sources and lower rank matrix approximations compared to other state-of-the-art algorithms. A necessary and suffi-cient condition for the uniqueness of the BFBM is also provided. Two algorithms based on multiplicative update rules are proposed and tested in numerical simulations, as well as on a real dataset. The gener-alization of this approach to the case of binary multidimensional arrays (tensors) leads to the boolean factorisation of binary tensors (BFBT). The proof of the necessary and sufficient condition for the boolean decomposition of binary tensors is based on a notion of boolean independence of binary vectors. The multiplicative algorithm based on the post nonlinear mixture model is extended to the multidimensional case. We also propose a new algorithm based on an AO-ADMM (Alternating Optimization-ADMM) strategy. These algorithms are compared to state-of-the-art algorithms on simulated and on real data

"The Post-consumer Waste Problem and Extended Producer Responsibility Regulations: The Case of Electronic Toys in British Columbia." Master's thesis, 2014. http://hdl.handle.net/2286/R.I.25864.
Full textAbstract:
abstract: Currently, consumers throw away products every day, turning those materials into waste. Electronic waste poses special problems when it is not recycled because it may contain toxic components that can leach into landfill surroundings and reach groundwater sources or contaminate soil, and its plastic, metal, and electronic materials do not biodegrade and are lost rather than recycled. This study analyzes a system that attempts to solve the electronic post-consumer-waste problem by shifting the economic burden of disposal from local municipalities to producers, reducing its environmental impacts while promoting economic development. The system was created in British Columbia, Canada after the province enacted a recycling regulation based on Extended Producer Responsibility (EPR), a policy strategy that is fast growing globally. The BC recycling regulation requires all e-toy corporations in BC to comply with a government-approved product-stewardship program to recover and dispose of e-toys after they have been discarded by consumers. In response to the regulation, e-toy corporations joined a Canadian non-profit entity that recycles regulated waste. I conducted a case study using in-depth interviews with the stakeholders to identify the outcomes of this program and its potential for replication in other industries. I derived lessons from which corporations can learn to implement stewardship programs based on EPR regulations. The e-toy program demonstrated that creating exclusive programs is neither efficient nor economically feasible. Corporations should expect low recycling rates in the first phases of the program implementation because EPR regulations are long-term strategies. In order to reach any conclusions about the demand of consumers for recycling programs, we need to measure the program's return rates during at least three years. I also derived lessons that apply to the expansion of EPR regulations to a broader scope of product categories. The optimal way to expand EPR policy is to do it by gradually adding new product categories to the regulation on a long-term schedule. By doing so, new categories can take advantage of existing stewardship programs and their infrastructure to recover and recycle the post-consumer products. EPR proved to be an effective option to make corporations start thinking about the end of life of their products.Dissertation/Thesis
