A broader research project was conducted about intergenerational relationships. The focus of this study was about adolescents’ experiences of care in relationships with people older than 60 years, who live in an environment where resources are constrained. Care usually occurs in relationships and can take either the form of practical care or emotional care, or both which can occur simultaneously. Practical care involves behaviours, while emotional care involves feelings. Both are aimed at attending to other people’s needs. Previous studies on intergenerational relationships and care largely focused on either informal and practical care-giving, which are mainly provided by adult children to older people; or on the informal and practical care-giving provided by grandparents to grandchildren. Research on relational experiences between Setswana-speaking older people and young adults in South Africa has indicated ambivalence in their relationships. While another South African study on the relational experiences between Setswana-speaking older people and their grandchildren, who are in their middle childhood, reported supportive and caring relationships. Limited research exists about care in the relationships between adolescents and older people. Care as a relational phenomenon in intergenerational relationships is explained by the Self-Interactional Group Theory (SIGT), and is used in this study as the theoretical framework. SIGT explains the interactional manifestation of intergenerational relations, and conceptualises that intergenerational relationships are continuously created and co-created, which influences the meaning that is attached to care. This theory further explains the intra-individual, inter-individual and group level interactions that take place between the adolescents and older people. According to SIGT, intergenerational interactions are embedded in the socio-cultural, socio-economical, socio-political and the physical environments in which they take place. This study was conducted in Vaalharts, situated in the Northern Cape Province of South Africa. This community is economically vulnerable and resources are constrained. A qualitative research method was used to describe adolescents’ experiences of care. Fourteen adolescents between the ages of 12 and 16 years participated in the research. Non-probability, purposive sampling was used to select the participants. The participants took part in the Mmogo-method ®, which is a visual participatory data gathering method, to elicit the experiences of care. Eight of the participants were part of the care-group, while the other six were part of the respect-group. All 14 participants received a journal with questions about care and respect to enlighten the data further. For this study, only the data about care was used. The Mmogo-method ® required the participants to build a visual presentation using clay, beads and sticks, about their experiences of care in relation to people older than 60 years. On completion, the rest of the participants were then asked to augment the individual’s explanation with their own views. The explanations were recorded and transcribed verbatim, while the visual representations were photographed and served as visual data. The data were analysed by the use of thematic and visual analysis. Trustworthiness was ensured by the use of credibility, dependability, transferability and conformability strategies. Additionally, the ethical guidelines provided by the Health Professions Council of South Africa for Psychologists were followed (Health Professions Act 56 of 1974). It was found that the adolescents were able to identify older people’s practical care and emotional care needs, and take action to provide them with appropriate care. The adolescents showed care in the form of practical activities, emotional support, showing respect, and obtaining an education. Findings further indicated that adolescents received care only in the form of practical care. These findings may be an indication that, from the adolescents’ perspective, there is an imbalance between the giving and receiving of practical and emotional care. Intervention programs can then focus on ways to help ensure that both practical and emotional care occurs in a more balanced manner. / MSc (Research Psychology), North-West University, Potchefstroom Campus, 2015

This thesis considers the case of mobile crime-reporting systems that have emerged as an effective and efficient data collection method in low and middle-income countries. Analyzing the data, can be helpful in addressing crime. Since law enforcement agencies in resource-constrained context typically do not have the expertise to handle these tasks, a cost-effective strategy is to outsource the data analytics tasks to third-party service providers. However, because of the sensitivity of the data, it is expedient to consider the issue of privacy. More specifically, this thesis considers the issue of finding low-intensive computational solutions to protecting the data even from an "honest-but-curious" service provider, while at the same time generating datasets that can be queried efficiently and reliably. This thesis offers a three-pronged solution approach. Firstly, the creation of a mobile application to facilitate crime reporting in a usable, secure and privacy-preserving manner. The second step proposes a streaming data anonymization algorithm, which analyses reported data based on occurrence rate rather than at a preset time on a static repository. Finally, in the third step the concept of using privacy preferences in creating anonymized datasets was considered. By taking into account user preferences the efficiency of the anonymization process is improved upon, which is beneficial in enabling fast data anonymization. Results from the prototype implementation and usability tests indicate that having a usable and covet crime-reporting application encourages users to declare crime occurrences. Anonymizing streaming data contributes to faster crime resolution times, and user privacy preferences are helpful in relaxing privacy constraints, which makes for more usable data from the querying perspective. This research presents considerable evidence that the concept of a three-pronged solution to addressing the issue of anonymity during crime reporting in a resource-constrained environment is promising. This solution can further assist the law enforcement agencies to partner with third party in deriving useful crime pattern knowledge without infringing on users' privacy. In the future, this research can be extended to more than one low-income or middle-income countries.

Patrick and Felicia are a couple who run a farm. Every day they harvest their crops and sell them at the local market. This is the family's everyday life and today's income goes to all the family'sexpenses such as food, water, and transport to the market. At the end of the day, the family's totalbudget results in plus or minus zero. The crop that was not sold must be thrown away because itrots during the night. If the family had a refrigerator, they would have been able to store the cropsand extend their life of it, which in turn gives them the opportunity to also sell the crops the nextday and earn more money. The crux of the family is that the cheapest refrigerator on the marketis far too expensive to buy and operate due to electricity costs. The cooler of MittiCool Clay is acooler made of clay that costs around 1000 SEK and does not need electricity. Instead, it uses thenatural laws of thermodynamics to cool the contents making it free to operate.This is an example of a scenario where a product can create value for a family living in a resourceconstrainedenvironment (RCE). The product can offer a possible way to be able to save moneyand eventually be able to afford schooling for their child, a savings capital for crises and healthcareThis thesis uses a human-centred design process to create a solution for this target group. Thechallenge for these particular people in this project is the low access to clean water.Through a need-finding process that resulted in 10 insights that served as a guide in the project.In three workshops and with a contoured idea generation process with residents and designteachers, a variety of ideas could be developed. The ideas were put together and became concepts.The concept was evaluated through an evaluation matrix based on the needs of the users, thetechnical possibility, and the potential financial sustainability. At the end of the evaluationprocess, one concept remained Life Cube. The concept is a franchise, product and a service thatenables residents to clean their grey cat through an off-grid "cube" to drinkable quality. Theconcept also provides an opportunity for a prospective cube owner to run his own business andoffer this service.Four billion people live at the bottom of the socio-economic pyramid and can be potentialcustomers. The feasibility study showed that there are very few products in this market today andthat the number of potential customers is large. Creating a so-called ‘frugal innovation’, combinedwith the fact that it is financially sustainable with very small funds, is complex. This requires thatthe innovator works locally with the user's specific needs and usually with local resources and thatthe local economic and physical infrastructure is considered.The conclusion is that one can use human-centred design to create products and services for peopleliving in a resource-constrained environment. The basis of the process is based on people's needs,economic situation, infrastructure, institutions, resource availability, which are essential factorsto consider for the solution desired by the user, technically viable and financially sustainable. Asecond conclusion is that the difficulties of product development towards this target group requireresources and knowledge that are not usually required in product development contexts towardsthe market that belonged to the top of the socio-economic pyramid, which can complicate theproduct development. / Patrick och Felicia är ett par som driver en odling. Varje dag skördar de sina grödor och säljer påden lokala marknaden. Det här är familjens vardag och dagens inkomst går åt till alla familjensutgifter som mat, vatten och transport till marknaden. I slutet av dagen så resulterar familjenstotalbudget i plus minus noll. Skörden som inte blev såld måste slängas för att den ruttnar ändåunder natten. Hade familjen haft ett kylskåp hade dom kunat förvara grödorna och förlängtlivstiden på den, som i sin tur ger dom möjligheten att även sälja grödorna dagen efter och tjänamer pengar. Kruxet för famlijen är att den billigaste kylen på marknaden är alldeles för dyr attköpa och driva på grund av elkostnaderna. Kylen av MittiCool Clay är en kyl gjord i lera somkostar runt 1000 SEK och istället använder termodynamikens naturlagar för att kyla innehållet,vilket gör att den inte kostar något att driva.Detta är ett exempel på ett scenario där en product kan skapa värde för en familj som lever i enresursbegränsad miljö (RBM). Produkten kan erbjuda en möjlig väg för att kunna spara pengaroch så småning om kunna ha råd med en skolgång till sitt barn, ett sparkapital för krissituationeroch sjukvård. Detta examensarbete använder en människocentrerad design process för attskapa en lösning mot denna målgrupp, alltså människor som lever i en resurs begränsad miljö.Utmaningen för just dessa personer i detta projekt är den låga tillgången till rent vatten.Genom en behovsidentifieringsprocess som resulterade i 10 stycken insikter som fungeradesom en guide i projektet. I tre workshops och med en konteurnelig idegenereringsprocess medlokala invånare och designlärare kunde en mängd ideer tas fram. Ideerna sammanfogades ochblev till koncept. Koncepten utvärderades genom en utvärderingsmatris som grundades påanvädnarnas behov, den tekniska möjligheten och den potentiellt finansiella hållbarheten. I slutetav utvärderingsprocessen återstod ett concept, Life Cube. Konceptet är en franchise, produkt ochen tjänst som möjligör för lokalbon att rena sitt gråvatten genom en off-grid “kub” till drickbarkvalité. Konceptet ger även möjlighet för en blivande kub-ägare att driva sin egen verksamhet ocherbjuda denna tjänst.Förstudien visade att det finns väldigt få produkter mot denna marknad idag och att antaletpotentiella kunder är stort. Fyra miljarder människor lever i botten av den socioekonomiskapyramiden och kan vara potentiella kunder. Att skapa en så kallat ‘frugal innovation’, ikombination med att den är finansiellt hållbar med väldigt små medel är komplext. Det kräver attinnovatören arbetar lokalt med användarens specifika behov och oftast med lokala resurser, samtatt den lokala ekonomiska och fysiska infrastrukturen tas i beaktning.Slutsattsen är att man kan använda människocentrerad design för att skapa produkter ochtjänster för människor som lever i en resursbegränsad miljö. Processens grund baseras påmänniskornas behov, ekonomsika situation, infrastruktur, institutioner, resurstillgängligheten,vilket är essensiella faktorer att ta hänsyn till för att lösningen ska vara önskvärd av användaren,teknisk möjlig och finansiellt hållbar. En andra slutsats är svårigheterna med att produktutvecklamot denna målgrupp kräver resurser och kunskap som vanligtvis inte krävs i produktutvecklingssammanhang mot marknaden som tillhör toppen av den socioekonomiska pyramiden, vilketkan försvåra utvecklingsarbetet.

Expectations regarding the contributions of academics to entrepreneurial activity in addition to their primary role of carrying out teaching and research have increased in recent years. Nevertheless, research on academic entrepreneurship has, to date, been carried out mainly in developed nations and there has been little emphasis on developing countries, particularly low income ones. Developing countries, when compared with developed nations, have been reported to face relatively high levels of resource scarcity that involve shortages of skills, finance, physical infrastructure, technology, and institutions needed for innovation and entrepreneurship. This gap in our knowledge leads to the main objective of this study, which is to investigate academic entrepreneurship in a resource constrained environment. Referring to the entrepreneurship and diversification literature, the current study argues that, as a strategy to extract value from a resource constrained environment, academic entrepreneurs may diversify their entrepreneurial engagements, which is named in this research as ‘plural activity’. In order to achieve the main objective, this thesis derives four specific objectives; namely, investigating the ‘plural activities’ of academic entrepreneurs, studying the motivations of academic entrepreneurs, examining the influence of multilevel causal factors on ‘plural activities’, and investigating the impacts of academic entrepreneurship on universities and wider economy. Sequential mixed methods were adopted in three stages; namely, an initial context specific data gathering stage, an on-line survey, and in-depth interviews. Initial context specific data were used to design two subsequent data collection phases. This approach was believed to improve the construct validity of the study. The main purpose of the on-line survey was to obtain a broad understanding of the entrepreneurial engagements of academics, while that of in-depth interviews was to obtain detailed context specific data, required to achieve research objectives. This sequential mixed method design of a survey being followed up by in-depth interviews was also considered to improve the internal validity of this research.The results suggested that entrepreneurial activity was a means of overcoming resource barriers in a resource constrained environment as opposed to resources are a means of becoming entrepreneurial in a resource rich environment. The majority of academic entrepreneurs had overcome resource and opportunity constraints by diversifying their entrepreneurial engagements. ‘Plural activity’ was found to generate synergies between multiple academic entrepreneurial activities. Diversifying into a greater number of different activities was found to generate more synergistic effects than diversifying into a limited number of similar activities. Nevertheless, there remained synergies between those who adopted different diversification strategies. Moreover, academic entrepreneurship was found to enable the overcoming of resource barriers to university teaching and research as well as deliver positive outcomes to universities and wider economy. Furthermore, it was evident that academics were initially motivated by ‘push’ motives and over time the influence of ‘push’ factors declined, while the impact of ‘pull’ motives increased. As a result of a lack of research capabilities of industry and funding for universities, there was a higher mutual interdependence between universities and industry. However, due to the unavailability of supportive mechanisms or formal institutional infrastructure to promote academic entrepreneurship, university-industry interactions were driven by individuals, and thus, were scattered and isolated. Policy implications and future research avenues were considered in conclusion.
