Despite considerable research that has focused on the attributes associated with evaluating and selecting advertising agencies, and an emerging body of literature emphasizing customer loyalty and retention, advertising agency-client investigations have often analysed these attributes in isolation. This created the need for models that represent the interrelated effects that engender retention and loyalty, especially for services, whereby evaluative as well as relational factors can influence buyer responses. Addressing this gap, this research developed and described the construct of buyer consideration sets to gain a better understanding of business relationships. This is with specific reference to advertising agency replacement considerations in the South African environment. This research contributes to the body of knowledge by providing a more complete, integrated view of customer retention and its determinants. A heuristic model was developed with consideration of theories that originate from the transactional cost theory, social exchange theory and economic and relational contract theories. This model was empirically tested using a mixed method approach. Data obtained from 116 respondents were subjected to factor and correlation analysis to explore the dimensionality of the retention construct. An important contribution of this study is the use of multi-item scales to measure and test retention. This research supports that retention is multidimensional and highlights the limitations of research that measure single factors related to retention. What started as a complex set of relationships has been defensibly and systematically simplified into a parsimonious model. This model postulates that retention is the result of a good working relationship between an advertiser and agency; service satisfaction; respect and support; clear terms of engagement; and conflict resolution. This work also offers insight into the nuances of each of these antecedents and offer new reliable scales for measurement of the items. In management practice, this model will provide advertisers with insights with regards to procurement decisions and supplier management. It can also provide valuable insight to agencies with regard to customer retention management. Findings of this study may also be extended to other high value professional service industries. / Business Management and Entrepreneurship / D. Com. (Business Management)

MESHWR / Department of Hydrology and Water Resources / Communities in South Africa have been noted to consume earthy materials such a soil among others. Geophagy is largely practised in the rural areas as opposed to urban places, and in these places the level of sanitation is low and people usual practice open defecation. The practice of Geophagia has been associated with cultural, medicinal, psychological, religious and nutritional deficiency among others. The aim of the study was to investigate the effects of open defecation on geophagic soils and water resources in Siloam village. The study also aimed to understand the reasons why people practice geophagia in Siloam village and the health effect associated with consumption of geophagic soils. To carry out the aim of the study, a questionnaire survey was conducted among women who practice geophagia between the ages of 18 and above in Siloam village. Two hundred and eighty-three (283) women were selected using snowball sampling method to take part in the study. From the (283) women, (200) women represent the geophagic group and (83) women represent the control group. The existing standard questionnaire adopted to generate data on human geophagia included aspects on demography, socio-economic, cultural, ecological, physicochemical aspects, indigenous knowledge and health effects of geophagic consumers. Participants were asked basic questions on why they practice geophagy, their geophagic material preferences, where they collect the geophagic material and other related questions. A total of twelve soil samples were collected from Siloam village, from the twelve soil samples collected eight were collected from sites known for geophagic practice and another four soil samples were collected from sites where geophagia is not practiced and the samples were used as control soil samples. All the twelve soil samples were analysed for the presence of geohelminths ova using Ammonium Bicarbonate Protocol (AMBIC protocol). The AMBIC protocol consists of four analytical procedures, namely, sample preparation, sample washing with AMBIC solution, geohelminths ova recovery through a modified zinc flotation method and microscopic analysis. vi Furthermore, a total of twelve water samples were collected from Nzhelele River and ponds water in Siloam village. From the twelve water samples, eight samples were collected close to where geophagic materials were collected and where open defecation is reported to be taking place and the remaining four water samples were collected randomly from Nzhelele river and water ponds in Siloam village and was recorded as a control group. A total of 12 water samples were analysed for total coliform and faecal coliform Escherichia Coli (E.coli) indicator using the membrane filter technique. The results from the administration of the questionnaire revealed there was prevalence in the practice of geophagia in the area. The study found that most of the villagers in Siloam consumed soil nearly on daily basis. According to the results, only women were involved in the geophagic practices in the area. Additionally, the study revealed that geophagic consumers were mainly in the age of child bearing age group and reddish and yellowish soils were the most preferred. Furthermore, the results showed that geophagic consumers in the area generally consumed soil commonly because of cravings and pregnancy, however, those who were not pregnant also consumed soil. The respondents reported that they mostly consumed clay and this material was consumed in its dry state and mostly unprocessed, if processed, it would be baked. This geophagic material was mainly found in the wild (riverbed, valley etc.); it was also found that most of the soil consumers did not know that the substances they consumed could be harmful to them. Among those who knew the consequences of consuming the material stated that soil consumption causes constipation, tooth decay, body poisoning, and abdominal pains. The results from the control group, 83 women who do not practice geophagia, aged between 18 and above, analysed using chi-square revealed a significant association of age with consuming soils (p<0.05), while there was no association of income source (p>0.05) and educational level (p>0.05) with consuming soils. Chi-square (χ2) analyses further revealed that there was no association of knowledge on the harmful nature of the substance (p>0.05), frequency of getting infections (p>0.05) and experiencing chronic illnesses (p>0.05) with frequency of consuming soils. vii The results of geophagic soils revealed the absence of geohelminths ova in the entire geophagic sample. Meaning geophagic consumers in Siloam village are not at risk of acquiring geohelminths infection which may be of potential risk to human health. However, geophagic consumers may be exposed to various other potentially hazardous biological and non-biological soil contents. The results of the water samples revealed that most of the water samples in the areas where open defection is reported to be practised had higher composition of faecal and total coliform bacteria. The composition was above the South African recommended standard for negligible risk of microbial infection. This has caused a great threat to those who consume soil collected near water resources, especially from riverbed and those who also use these water sources on their daily basis. The study recommends that geophagic consumers should continue to bake their materials before consumption as it might reduce the bacteria and toxic substances found in soils. The study also recommends that the residents of Siloam be made aware of the potential health hazards that might be posed to soil consumers and the effects of practicing open defecation near community water resources as high level of faecal coliform (E. coli) were found in the water. / NRF

Det finns studier som visar att sjöfarten har svårt att bibehålla unga sjöfarare inom sjömansbranschen. Forskning visar att yngre sjömän har en större tendens att avbryta sin karriär till sjöss och är mer receptiva för erbjudande från landbaserade arbetsplatser än de äldre sjömännen. Mot denna bakgrund har syftet med detta arbeta varit att undersöka vad som gör att en nautiker stannar inom sjöfartsyrket, vilka faktorer som påverkar ett val att gå iland och om ålder och generationstillhörighet har någon inverkan i synen på karriären. För att få fram ett resultat hölls det kvalitativa intervjuer. Resultatet påvisar att det är ledigheterna som lockar med ett yrke till sjöss. Anledningen till att seniorbefälen har stannat till sjöss så länge är att de har trivts och haft möjlighet att utvecklas. Resultatet visar även att detta är något som de studerande respondenterna tycker är viktigt för att det ska arbeta till sjöss hela sitt yrkessamma liv. En annan slutsats som drogs var att ålder inte har någon påverkan på hur en person ser på sin karriär till sjöss och att alla respondenterna var överens om att organisationen fungerar bäst med en besättning i varierande åldrar. / There are studies that show that the shipping industry has a hard time keeping young seafarers. There has been researches that show that young seafarers have a higher tendency to discontinue their career at sea and are more receptive for offers from land-based companies then the older seafarers. Against this background the purpose of this study has been to examine what makes a seafarer stay within the shipping industry, what factors influence a seafarer’s choice to go ashore and if age and generational affiliation has an impact in the perception of a lifelong career at sea. To obtain a result, qualitative interviews were held. Results show that it is the long vacations that attracts the seafarer to choose a life at sea. The reason that the older seafarers have stayed in this profession for a long period of time is because they have enjoyed their time on board and there has been a possibility to evolve. The results also show that this is something that the studying respondents think is important for them if they are to work at sea their entire career. Another conclusion that was drawn was that age doesn’t affect a person´s view of a career at sea and all respondents agree that the organization onboard works best if the crew is of mixed age.

Over the past decade, technologies that facilitate household electricity production and storage have seen a rapid development along with a significant cost reduction. Research points to an increased share of household-produced electricity within the existing national grids across the globe. In some cases, self-sufficiency is possible where households are able to decouple from the grid and become independent on their electricity, in other words, go off-grid. Furthermore, this change puts additional pressure on how the electricity system is set up, which, challenges prevailing incumbents to adapt. Depending on the geographical location, circumstances for selfsufficiency varies. Sweden is a country with high seasonal variations with its Northern position, which raises the question of how off-grid households are feasible and, how they can receive traction. To investigate possible changes within large technical systems such as the electricity system, which is a vital part of the society, theories within socio-technical systems have shown much promise. However, these theories often lack the more techno-economic aspect of concrete and future investment costs from a consumer perspective, suggesting an existing research gap. Hence, the purpose of this study is to provide further knowledge regarding off-grid applications in the Swedish Context. This is done by investigating what circumstances could trigger existing electricity consumers to go off-grid. The research process and structure of the report can be interpreted as indiscriminate, however, the study has focused on combining theories surrounding socio-technical changes whilst applying techno-economic modelling to strengthen the work, similar to a dual paper study. Data was collected in the form of a literature review and interviews to provide a holistic representation of off-grid and its nexus to the electricity system. In addition to this, complementing modelling of grid-connected-, prosumer-, and off-grid households were performed. Results point towards a scene where off-grid reaches grid parity within the coming two decades, which, will increase the economic rationale of investing in an off-grid. Opposingly, there is currently no economic rationale in off-grid applications considering the relatively low electricity costs in Sweden as of today. Moreover, conditions show promise if the adopters see beyond economics and, possesses a strong will towards independence. However, implications suggest that the high reliability and low costs of the Swedish electricity grid impedes the ability of new radical innovations to receive traction. Furthermore, this study has contributed by filling the research gap between socio-technical changes and techno-economic projects in regards to electricity systems. Consequently, contributing to the academic field of socio-technical change, it has been shown that the combination of socio-technical change and techno-economic projections is applicable and beneficial. Additionally, it can be argued that the results of this study highlight that the consumer have a greater role in the development of off-grid applications than what the theories suggest. Lastly, the electricity system is a complex mechanism and, to further strengthen the perception of how a relatively new application, as in the case of off-grid, will impact the system, appurtenant suggestions for possible future research within the area are proposed. / Under det senaste decenniet har teknik som underlättar hushållens elproduktion och lagring haft en hastig utveckling tillsammans med en betydande kostnadsminskning. Forskning pekar på en ökad andel hushållsproducerad el inom de befintliga nationella elnäten över hela världen. I vissa fall är självförsörjning möjligt där hushållen kan koppla bort sig från nätet och bli oberoende av sin elförsörjning, med andra ord gå off-grid. Vidare leder en potentiell förändring mot offgrid till ytterligare påtryckningar på hur elsystemet är uppbyggt, vilket utmanar många aktörers sätt att agera. Beroende på geografisk plats så varierar förutsättningarna för självförsörjning. Sverige är ett land med stora säsongsvariationer i och med sin nordliga position, vilket väcker frågan om off-grid hushåll är genomförbara i Sverige och hur de kan skulle kunna etableras. För att undersöka möjliga förändringar inom stora tekniska system som elsystemet, som är en viktig del av samhället, har teorier inom socio-tekniska system visat vara till stor nytta. Däremot saknar dessa teorier emellertid den mer tekno-ekonomiska aspekten av konkreta och framtida investeringskostnader ur ett konsumentperspektiv, vilket antyder ett befintligt forskningsgap. Följaktligen är syftet med den här studien att ge ytterligare inblick om off-grid-applikationer i svenska sammanhang. Vilket har gjorts genom att undersöka vilka omständigheter som kan leda till att befintliga elkonsumenter går off-grid. Forskningsprocessen och strukturen i rapporten kan vara svårtolkat, men studien har fokuserat på att kombinera teorier kring socio-tekniska förändringar samtidigt som man använder teknoekonomisk modellering för att stärka arbetet. Data samlades in i form av en litteraturstudie och intervjuer för att ge en holistisk representation av off-grid och dess koppling till elsystemet. Utöver litteraturstudie utfördes kompletterande modellering av hushållsanslutna, prosumeroch off-gridhushåll. Resultaten pekar mot scenarion där off-grid når nätparitet under de kommande två decennierna, vilket kommer att öka den ekonomiska rationaliteten för att investera i ett off-grid. Det finns det för närvarande inga ekonomiska skäl till att investera off-grid-applikationer med tanke på de relativt låga elkostnaderna i Sverige idag. Förhållandena visar dessutom löfte om att potentiella användare ser förbi ekonomin och har istället en stark vilja mot självständighet. Implikationer tyder emellertid på att det svenska elnätets höga tillförlitlighet och låga pris hindrar nya radikala innovationers förmåga att ta få fäste. Det är argumenterbart att den här studien har bidragit med att fylla forskningsgapet mellan socio-tekniska förändringar och tekno-ekonomiska projektioner inom elsystem. Samtidigt har studien bidragit till det vetenskapliga området kring socio-tekniska visat på möjligheten och fördelen i att kombinera teorier kring socio-teknisk förändring och tekno-ekonomiska förändringar. Dessutom kan det hävdas att resultaten av den här studie visar att konsumenten har en större roll i utvecklingen av applikationer utanför nätet än vad teorierna föreslår. Slutligen är elsystemet en komplex mekanism, och för att ytterligare stärka uppfattningen om hur en relativt ny applikation, som i fallet utanför nätet, kommer att påverka systemet föreslås lämpliga förslag för eventuell framtida forskning inom området.
