I denna uppsats testar jag kausalitet mellan marknadsskapande institutioner och tillväxtrelaterade variabler samt omvänt. Detta görs på en panel bestående av 15 länder i Central- och Östeuropa (CEE) under perioden mellan år 1996 och 2019. Metoden bygger på test för Granger-kausalitet i paneldata, SY-GMM med faktoriserade instrument och kvantilregression. Resultaten indikerar svagt på en utbytesrelation men är inte robust och slutsatser är därför att kausalitet ej kan påvisas i någon riktning. AI har använts för att extrahera test för unit root och sätta asterisker på regressionskoefficienterna. / In this thesis I apply methods for panel data analysis in order to test the causal relationship between market engaging instituions and economic growth. The panel consists of data gathered from multiple institutional indices and covers 15 countries in Central and Eastern Europe (CEE) between the years 1996 and 2019. The methods include panel Granger-causality tests, SY-GMM with factorized instruments and panel quantile regression. The findings are inconclusive but suggests a feedback relation between institutional measures and growth related variables. The conclusion however, is that causality can not be indentified in any direction. AI has been used to extract p-values from tests for unit root and to add asterisks to the regression coefficients.

Esta pesquisa teve como objetivo explicar a gestão municipal de tributos pelas regras de controle fiscal na arrecadação do Imposto Sobre Serviços de qualquer natureza, quando fortalecidas pela tecnologia da internet, sob uma perspectiva da Nova Economia Institucional (NIE), com ênfase na visão da sua vertente a Economia de Custos de Transação (TCE). Por meio de um estudo de caso único (piloto), identificaram-se os procedimentos de controle fiscal e analisou-se o fluxo das informações processadas e os resultados econômico-sociais proporcionados. Seguiu-se com um estudo de casos múltiplos de dez Municípios do Estado de São Paulo (Brasil), a partir de um modelo lógico elaborado em função das conclusões do estudo piloto, apurando-se o aumento da capacidade de controle pela ampliação da quantidade, agilidade e qualidade das informações processadas, que diminui, ainda que limitadamente, a assimetria de informações entre as partes, podendo gerar uma redução nos custos de oportunismo presentes nos custos de obtenção da informação que, se produzida, reflete um acréscimo do valor de imposto pago pelo contribuinte, alterando o desempenho da arrecadação do ISS para o Fisco municipal. O uso da tecnologia revelou-se fortalecedor para as regras de Controladoria e Contabilidade Gerencial existentes na área fiscal municipal. / This research aims at explaining the municipal management of taxes according to the fiscal control rules about collecting the ISS (tax on services of any nature), when strengthened by the Internet technology, based on a perspective of NIE (New Institutional Economics), with emphasis on the viewpoint from the TCE (Transaction Costs Economics). Through the study of a unique case (pilot), the procedures of fiscal control were identified and the flux of processed information and its socio-economic results were analyzed. Furthermore, multiple case studies of ten municipalities of the State of Sao Paulo were studied, underpinned by a logical model developed from the conclusions of the pilot case, of which resulted in the increase in the control capacity through the amplifying of quantity, agility and quality of processed information, which decreases, in a limited manner, the asymmetry of information between the parties and therefore generating a reduction in the opportunism costs found in the costs of information gathering, which when produced reflects an addition in the amount of tax paid by the tax payer, altering the accomplishment of the collection of ISS to the municipal Revenue. The use of technology revealed itself to strengthen the rules of the controlling and management accounting that exist in the municipal tax area.

The aim of the study was to examine and describe how divorced biological fathers in reconstituted families give form to the educational relationship with their non-resident young children, to achieve an understanding of fathers’ perceptions of their parental roles as well as the functionality of the relationship in practice. A multiple case study using semi-structured interviews was conducted. A meta-analysis of the emergent themes indicated that the field within which understanding of the phenomenon should be constructed, ranges beyond the context of the fathers reconstituted families who participated in the study. The literature review confirmed that the relationship between former marriage partners plays an important part in fathers’ ongoing relationship with their non-resident child/ren. Findings: • The interaction in the mesosystem between the primary and secondary micro family systems of the two parents with and without custody influences the way in which the biological fathers endeavour to establish/maintain a relationship with their non-resident child/ren. Within this unique mesosystem various obstacles and potential traps exist that could prevent fathers from giving form to their educational relationship with their non-resident child/ren. • By identifying and mobilising assets and strengths the focus could shift from fathers’ feelings of frustration and powerlessness to feelings of empowerment and self-determination that could promote optimal relations. / Dissertation (MEd (Educational Psychology))--University of Pretoria, 2006. / Educational Psychology / MEd / unrestricted

Nuwe kommunikasie- en inligtingstegnologie vorm ’n individu se persepsies en hoe hulle ’n spesifieke organisasie sien. MSF Suid-Afrika se webtuiste (met spesifieke verwysing na die foto’s wat gebruik word op die webtuiste) is een van die kommunikasie- en inligtingstegnologieë wat ’n invloed sal hê op die persepsies van die organisasie se belangegroepe. MSF moet krities dink oor die foto’s wat hulle op hulle webtuiste plaas, aangesien dit moontlik die kommunikasie tussen die vrywilligers en die organisasie, sowel as die persepsies van vrywilligers, kan beïnvloed. Dit is van belang vir MSF om deur die foto’s wat hulle op MSF Suid-Afrika se webtuiste plaas die publiek in te lig oor die omstandighede van die populasie waarbinne die veldwerkers werk. Persepsies rig denke en besluite – problematiese uitdagings kan ontstaan indien hierdie persepsies in kontras staan met die persepsies wat MSF graag wil vorm met die gebruik van foto’s op hulle webtuiste. Die studie fokus vervolgens op die persepsies van potensiële vrywilligers van MSF, met spesifieke fokus op die foto’s gebruik op MSF Suid-Afrika se webtuiste. Die algemene doelstelling van hierdie studie is om vanuit ’n organisasiemediabestuursperspektief te bepaal watter rol foto’s op MSF Suid-Afrika se webtuiste speel in die persepsievorming tydens kommunikasie met potensiële vrywilligers as belangegroep. Die hoof bevindinge van die studie toon dat foto’s ’n rol speel om betekenis by te dra tot kommunikasie met belangegroepe, en dat die impak van die foto’s op MSF se webtuiste ’n rol speel in potensiële vrywilligers se persepsievorming. MSF kan meer fokus op die rol wat foto’s in die kommunikatiewe proses speel. Potensiële vrywilligers het verder aangetoon dat hulle meer persoonlike aandag vanaf MSF wil hê. Daar is ook gevind dat dit van belang is dat MSF se webtuiste visueel aanloklik moet wees en dat die foto’s wat op die webtuiste gebruik word akkuraat en geloofwaardig moet wees. MSF se sukses kan verbeter as hulle meer aandag aan potensiële vrywilligers gee. Respondente het verskillende voorstelle gemaak vir hoe MSF meer vrywilligers kan werf. Die studie dra by tot die belangegroepbestuur tussen MSF Suid- Afrika en hulle potensiële vrywilligers. Dit bied aan MSF Suid-Afrika geleentheid om beter te verstaan wat ’n steekproef van potensiële vrywilligers tans dink van die gebruik van foto’s op hulle webtuiste. / MA (Communication Studies), North-West University, Potchefstroom Campus, 2015

The Wonderfontein Cave is located within the Witwatersrand Basin (Gauteng province, South Africa) and is associated with the river banks of the Wonderfontein Spruit. This cave system has for many years been subjected to the influx of polluted mine water. Since subterranean environments remain poorly studied, it is unknown what the effect of this might be on the associated ecosystem. Furthermore, water that enters the Wonderfontein Cave poses a severe health threat as it drains into the underlying aquifer, which is abstracted for human and animal use. The general aim of this study was to determine the extent of metal pollution (enrichment), as well as to study the toxicity hazard potential of the soils and sediments associated with the Wonderfontein Cave. The objectives of this study were to (1) quantify the extent of anthropogenic metal pollution of water, soils and sediments associated with the Wonderfontein Cave (2) and assessing the toxicity hazard potential of these substrates; (3) determining whether nematode taxa and C. gariepinus individuals represent isolated communities and a population within the Wonderfontein Cave, respectively; (4) measuring the effect of mining-associated pollutants on the soil and sediment health of the Wonderfontein Cave by making use of nematodes to serve as bioindicators; (5) evaluating and comparing biomarker responses to metal bioaccumulation in C. gariepinus populations associated with the Wonderfontein Cave and epigean (surface) environments and lastly (6) comparing the results of the above identified assessments over both a temporal and spatial scale. Sampling was undertaken during April (1st sampling interval) and September (2nd sampling interval) 2013, which respectively represented the end of the high and low flow periods. Also, sampling of the subterranean (Wonderfontein Cave) and associated surface (Wonderfontein Spruit) environments were undertaken. The findings of this study suggested that especially the sediments associated with the Wonderfontein Cave have been subjected to severe nickel, copper, zinc, cobalt, aluminium, cadmium, lead and uranium enrichment. Also, the concentrations of many of the studied metals exceeded the respective water, soil and sediment environmental quality guidelines. Thus, also taking into consideration that most of the sediments were classified as being toxic, a severe threat is posed to the health of the associated biota. Although 60 nematode genera were identified from soil and sediments samples collected from the respective sampling sites associated with the Wonderfontein Cave and Spruit, it was concluded that most of these genera were likely only temporary residents of the subterranean environment. Even though plant-parasitic and nonparasitic nematodes were present, most of the collected soil and sediment samples were dominated by bacterivores (non-parasitic nematodes). Zero genetic divergence was recorded between the C. gariepinus populations associated with the Wonderfontein Cave and Stoffels Dam (Wonderfontein Spruit). However, significant temporal and spatial variation was observed in some bioaccumulated metals and biomarker responses within and between the respective C. gariepinus populations. Furthermore, the metal bioaccumulation levels present in both these fish populations pose a substantial threat to human health and are thus not fit for consumption. Also, no significant fish condition differences were observed between the C. gariepinus populations associated with the Wonderfontein Cave and Spruit. This study served as an initiative to create awareness and promote the conservation of Africa’s karst landscapes. / MSc (Environmental Sciences), North-West University, Potchefstroom Campus, 2015

Diabetes mellitus is a complex disease that requires constant patient compliance to diet, life style, glucose level monitoring and medication. Non-compliance to medication can be associated with the development of complications, avoidable hospitalization, disease progression, premature disability and death. Noncompliance is also very costly and therefore compliance to medication regimens is very important. A promising, yet under-explored approach to compliance is self-regulation. Selfregulation refers to the process of goal setting and striving. Self-regulation has specifically been associated with success in reaching one’s goals. The key selfregulation processes include goal establishment, planning, striving towards a goal and revising it. Although a large number of studies have been conducted on compliance related to diabetes, there is a lack of research findings from a selfregulation perspective. The aim of this study is to investigate the relationship between self-regulation and patient compliance to type I and type II medication. Specific aims are (a) to determine whether there is a significant difference in the mean self-regulation scores for participants high and low in compliance and (b) to determine whether there are significant differences in the mean self-regulation scores between compliant and non-compliant participants within different gender and age groups. The participants consisted of an availability sample of 50 (31 female and 19 male) type I and type II diabetes patients collecting their medication at the Clicks Pharmacy in Potchefstroom and Trans 50 retirement villages in Pretoria, Bloemfontein and Kimberley. The ages of the participants ranged between 20 and 87 years. Compliance was measured by investigating the participants’ repeat scripts as well as the Clicks Medication Therapy Management Questionnaire (MTM-Q), developed in 2009 by pharmacists at Clicks to measure patients’ self-report of compliance. Selfregulation was measured with the Shortened Self-Regulation Questionnaire (SSRQ) (Carey, Neal, & Collins, 2004). The study used the factor structure proposed by Potgieter and Botha (2009), based on a factor analysis of the SSRQ in the South- African context. Data capturing and analysis was done in consultation with the Statistical Consultation Services of the North-West University. A total number of 28 (56%) participants in this study were classified as compliant, which is lower than compliance figures reported in most international studies. Differences between compliant and non-compliant participants were primarily noted with regard to Mindful Awareness, Monitoring and Decision making. No differences were noted between any of the groups regarding Learning from mistakes, Perseverance, or Self-evaluation. Compliant participants in the total, female and older groups scored higher on Mindful Awareness than non-compliant participants. For older participants, this difference was practically significant. Compliant participants in the female and older group also obtained higher scores on Monitoring, with the difference in the female group practically significant. Surprisingly, noncompliant female participants scored higher on Decision Making than compliant female participants. Compliant and non-compliant male and younger participants, however, did not differ on any of the self-regulation factors. The study emphasizes the fact that diabetes is perceived as a significant challenge to the current goals of the patient. Subsequently, this study confirms, to a large extent, the importance of self-regulation in compliance to type I and type II diabetes medication, providing support for international studies that emphasise the importance of behavioural factors in diabetes. Mindfulness and Monitoring emerged as important factors in this study, and was explained in relation to compliance as a challenge to one’s perceptual awareness and ability to continuously generate feedback regarding one’s health status. The reason for gender and age related differences in the relationship between compliance and self-regulation, however, is not totally clear and needs to be explored in further research. An important limitation of the study is the small sample size that was used. Future research should explore the trends emerging from this study in larger, random samples. / MA (Research Psychology), North-West University, Potchefstroom Campus, 2014
