abstract: Life History Theory suggests that, in order to maximize reproductive fitness, individuals make trade-offs between allocating resources to mating and parenting. These trade-offs are influenced by an individual's sex, life history strategy, and environment. Here, I explored the usefulness of a Life History Theory framework for understanding endorsement of child support laws. This study experimentally manipulated sex ratio, and gathered information about participants' endorsement of child support, sexual restrictedness, and mate value. As predicted, women endorsed child support more than men, whereas men favored greater restriction of child support in the form of required paternity testing. However, in general, results do not support an effect of sex ratio, sexual restrictedness, or mate value on endorsement of child support. Results suggest sensitivity to exploitation in a male-biased sex ratio, reflected by an increase in men's endorsement of paternity testing requirements under a male-biased sex ratio prime. Women, on the other hand, report especially unfavorable beliefs toward paternity testing in a male-biased sex ratio. Although results of the current study are mixed, there remains much to be gained from applying an evolutionary perspective to understanding variability in endorsement of child support. / Dissertation/Thesis / M.A. Psychology 2013

[pt] A percepção de risco em compras online é apontada por diversos autores como o obstáculo para o crescimento do comércio eletrônico. O varejo pela Internet torna impossível a avaliação de atributos tangíveis pela impossibilidade de examinar fisicamente o produto. No caso de alimentos, a Internet ainda é um canal muito pouco explorado, já que as conseqüências de um produto estragado podem ser potencialmente severas, causando danos à saúde. Este estudo pretendeu, através de um levantamento em uma amostra dos clientes de uma rede de supermercados do Rio de Janeiro, comparar o risco percebido na compra online de alimentos perecíveis por clientes dos diversos canais do supermercado. Os resultados apresentaram evidencias de que a compra de alimentos perecíveis é percebida como mais arriscada por clientes da loja física do que clientes da Internet e que o risco de desempenho/físico desempenha o papel mais importante na percepção do risco total. / [en] The perceived risk in online shopping is seen by many authors as an obstacle for the growth of electronic commerce. The online retailing makes impossible for customers to evaluate the tangible attributes due the impossibility of physical examination of the product. In the case of groceries, the Internet still is an unexplored channel, once the consequences of a spoiled product can be potentially severe, causing damage to one`s health. This study intended, through a sample of customers of a supermarket chain located in Rio de Janeiro, to compare the perceived risk in online shopping of groceries through customers of different channels of the supermarket. The results presented evidences that the shopping of groceries is perceived as more risky by costumers of physical store than by costumers of Internet and that the performance/physical risk represents the most important role in risk perception.

Magister Artium (Development Studies) - MA(DVS) / This research study addresses the effectiveness of child support grants in South Africa. It specifically asks the questions, what do social policy makers in South Africa want to achieve with the Child Support Grant (CSG) and are they achieving it? If not, how can policy makers ensure that social grants achieve the desired impact? The researcher will establish the effectiveness of the current CSG and how the CSG programme design and implementation might be improved for the CSG system to have its desired effect for children and at the family level.

There is a disproportionate number of African American fathers in the State of Tennessee that experience parenting and child support disparities when compared to single parents of other ethnicities. The purpose of this general qualitative study was to examine the experiences of African American noncustodial fathers and to examine the impact of the codification of Tennessee family laws. The theoretical frameworks for this study were critical race theory, and social construction and policy design. The key research questions examined the lived experiences of African American noncustodial fathers in the State of Tennessee and how the codification of Tennessee family laws contributed to the social construction of African American noncustodial fathers. The general qualitative study included both phenomenological and historical techniques. The data was collected by in-depth interviews of 8 African American noncustodial fathers. The study resulted in 5 emergent themes: many were happy to become fathers; many have no relationship with their child's mother; child support negatively impacted their lives; child support is biased and unfair; and the fathers wanted more time with their children. The State of Tennessee and African American fathers will benefit from the study by replicating the research statewide. Specifically, the role of fathers will be increased, less adversarial co-parenting, and legislators will have scholarly research to show the issues with the laws. The implications for positive social change include lower crimes rates related to child support, increased graduation rates, and enhanced father-child time.

The fulfilment of Child Support payments following divorce is important to ensure children’s wellbeing. Guided by a model of normative influences, we investigated how individuals perceived Child Support payments in South Korea and the United States and if they varied by child’s gender, custody arrangements, changes in the responsible father’s finances, and his financial obligations to an aging parent. Both quantitative and qualitative data were collected from 132 Korean and 132 U.S. participants by utilizing a multiple segment factorial vignette (MSFV). Korean respondents believed more Child Support should be paid than did U.S. respondents. Custody arrangements and changes in the fathers’ finances affected perceived financial obligations of divorced fathers to the child regardless of participants’ country. Having an aging parent in need affected Koreans’ perceptions about Child Support in different ways than U.S. participants. Qualitative responses indicated that Koreans emphasized paternal obligations, whereas U.S. participants stressed the issue of fairness as a rationale. We discuss the results of this study in relation to Child Support compliance in both countries and suggest implications for research and practice.

A Research Report submitted in partial fulfilment of the Degree of Master of Commerce (Economic Science) in the School of Economic and Business Sciences, University of the Witwatersrand, 28 February 2019 / This paper investigates the impact of the South African Child Support Grant (CSG) on the beneficiary’s height-for-age z-score (HAZ). We make use of data from the National Income Dynamics Study (NIDS), the wave 3 dataset. Using Propensity Score Matching approach the effect of the CSG is positive but statistically insignificant and relatively small. This popular technique rely on assumptions that often do no hold for observational studies. Furthermore, it is susceptible to misspecification of the propensity score equation which could bias the results. This paper therefore look into a technique that address these limitations and can assess the treatment effect robustly and with more precision. We apply genetic matching algorithm, namely GenMatch. GenMatch is an iterative search algorithm that uses distance metrics to optimize covariate balance in the process of estimating the treatment effect. It automates the search process without the need of manual intervention to achieve the best balance. This algorithm is applied using two balance measures namely, the entropic distance metric and the standardized difference in means. The former compares distributions while the latter compares the first two moments (means and variances) of distributions. The results showcase the significance of utilizing a method that automates the process of optimizing balance and the influence of balance measures on the resulting treatment effect estimate. Specifically, we found that the estimate of the effect of the CSG is larger and more precise than the one reported in the literature. / PH2020

Thesis (PhD)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: This study focused on the social protection of vulnerable children in Zambia. The aim was to find out how social protection had evolved and how it was conceptualised – its functions and types, policies and programmes, the benefits and services, and the risks and vulnerabilities that it addresses. A descriptive study design was used with qualitative methods of collecting and analysing data. The sample of 24 participants from government and nongovernmental organisations involved in social protection delivery as well as carers of children was drawn from the Central, Lusaka and Southern provinces of Zambia respectively. A semi-structured interview schedule was used, and all the recorded interviews were transcribed by the researcher and sent back to the participants for proofreading or corrections, where necessary, before analysis. The basic needs, the empowerment, the risk management, the rights-based, and the capability approaches have been used to further the conceptualization, design features and implementation modalities of social protection. Additionally, given that a theoretical basis for social protection is still lacking, the study drew on representational, explanatory, normative, human capital, social construction, social contractual, and structural social work theories in order to complement, extend and verify the findings. Ethical clearance (number Desc_Moonga2012) was obtained from Stellenbosch University’s Research Ethics Committee. The ethical clearance certificate was used to apply for and obtain permission from the Zambian Ministry of Community Development Mother and Child Health and nongovernmental organisations involved in the study. Empirically, the study found that social protection was an old activity under a new name and was being scaled up rapidly but biased towards cash transfers. By and large, social protection in Zambia is provided as unconditional transfers, mainly as social assistance. No existing legislative or policy framework specifically focused on social protection was found, although the latter had been drafted at the time of the study. The Zambian government and a number of partners such as CARE, Child Fund, World Vision and the World Food Programme, to mention only a few, were found to be involved, but their efforts were fragmented and interventions for children were limited, fragmented and less responsive to the current risks and vulnerabilities of children. The study also established that if 2–3% of the country’s gross domestic product as recommended by the International Labour Organization were used, Zambia could afford to provide extensive social protection coverage (beyond its current offering) by using local resources. However, this would require putting in place appropriate and sustainable resource mobilisation measures and decentralization of the processes and interventions. Based on these and other concluding findings, it is recommended that in order for social protection for vulnerable children in Zambia to be effective, among other requirements, political will is needed in the provision of social protection for vulnerable groups, especially children, through legislative and policy frameworks. Additionally, there is a need for sustainable resource mobilisation, especially through progressive taxation such as taxation of undeserved income and taxation of big businesses, especially mining companies. However, due to limitations in qualitative methods and descriptive designs and the small sample of the data used, the conclusions and recommendations of the study are but conjectural. / AFRIKAANSE OPSOMMING: Hierdie studie het op die maatskaplike beskerming van kwesbare kinders in Zambië gekonsentreer. Die doel was om te bepaal hoe maatskaplike beskerming ontwikkel het en gekonseptualiseer is – die soorte en funksies van maatskaplike beskerming, die beleide en programme daaroor, die voordele en dienste wat daarmee verband hou, en die gepaardgaande risiko’s en kwesbaarhede. ʼn Beskrywende navorsingsontwerp met kwalitatiewe metodes vir data-insameling en -ontleding is gebruik. Die steekproef van 24 deelnemers uit die staatsektor en nieregeringsorganisasies wat met die lewering van maatskaplike beskerming gemoeid is, sowel as kinderversorgers, het uit die Lusaka-, sentrale en suidelike provinsies van Zambië gekom. ’n Semigestruktureerde onderhoudskedule is gebruik. Die navorser het alle opnames van onderhoude getranskribeer en dit voor ontleding aan die deelnemers gestuur om te proeflees en enige nodige regstellings te maak. Die basiese behoefte-, bemagtiging-, risikobestuur-, regsgebaseerde en vermoëns benaderings is gebruik om die konseptualisering, ontwerp kenmerke en implementering van modaliteite van maatskaplike beskerming te bevorder. Benewens die gebrek aan ’n teoretiese grondslag vir maatskaplike beskerming, het die studie op die verteenwoordigende- verklarende-, normatiewe-, menslikekapitaal-, maatskaplikekonstruksie-, maatskaplikekontrak- en strukturele maatskaplikewerk-teorieë staatgemaak om die bevindinge aan te vul, uit te brei en na te gaan. Etiekgoedkeuring (nommer Desc_Moonga2012) is van die Universiteit Stellenbosch se Navorsingsetiekkomitee verkry. Die etiekgoedkeuringsertifikaat is op sy beurt gebruik om toestemming te vra en te verkry van die Zambiese Ministerie van Gemeenskapsontwikkeling en Moeder- en Kindergesondheid en nieregerings-organisasies wat by die studie betrokke was. Die empiriese bevinding van die studie is dat maatskaplike beskerming ’n ou aktiwiteit met ’n nuwe naam is, en dat dit vinnig uitgebrei word, dog na kontant-oorplasings oorhel. Maatskaplike beskerming in Zambië geskied merendeels as onvoorwaardelike oorplasings, hoofsaaklik in die vorm van maatskaplike bystand. Geen bestaande regs- of beleidsraamwerk wat bepaald oor maatskaplike beskerming handel, kon opgespoor word nie, hoewel werk aan ’n beleidsraamwerk ten tyde van die studie aan die gang was. Die Zambiese regering en ’n aantal vennote, waaronder CARE, Child Fund, World Vision en die Wêreldvoedselprogram, om net enkeles te noem, is betrokke by maatskaplike beskerming dienslewering, maar hul pogings is gefragmenteer. Veral intervensies vir kinders is beperk, gefragmenteer en nie juis ingestel op die kinders se huidige risiko’s en kwesbaarhede nie. Daarbenewens het die studie vasgestel dat indien 2–3% van die land se bruto binnelandse produk gebruik word, soos wat die Internasionale Arbeidsorganisasie aanbeveel, Zambië kan bekostig om met behulp van plaaslike hulpbronne omvattende maatskaplike beskerming (wat verder strek as sy huidige aanbod) te bied. Dít sou egter vereis dat toepaslike en volhoubare maatreëls en desentralisering van prosesse en intervensies ingestel word om hulpbronne te mobiliseer. Op grond van hierdie en ander bevindinge is die gevolgtrekking dat maatskaplike beskerming vir kwesbare groepe in Zambië slegs doeltreffend sal wees indien die nodige politieke wil bestaan om deur regs- en beleidsraamwerke maatskaplike beskerming aan hierdie groepe, veral kinders, te voorsien. Daar bestaan ook ’n behoefte aan volhoubare hulpbronmobilisering, veral deur progressiewe belasting soos belasting op onverdiende inkomste en belasting op groot ondernemings, bepaald mynmaatskappye. Weens die beperkinge van kwalitatiewe metodes en deskriptiewe ontwerpe, sowel as die klein datasteekproef wat gebruik is, is die gevolgtrekkings en aanbevelings van die studie egter bloot verondersteld.

[pt] Gorduras trans são definidas pelo Codex Alimentarius como ácidos graxos insaturados que contém pelo menos uma dupla ligação trans. As gorduras trans de origem industrial são formadas durante a transformação pela hidrogenação parcial de óleos vegetais líquidos em gorduras semi-sólidas. Estas são amplamente usadas na fabricação de alimentos processados. Em 2002, um relatório da FAO/OMS, apresentou prova convincente de que a ingestão de gorduras trans aumentava efetivamente o risco de doenças cardiovasculares, e recomendou que seu consumo não deveria exceder 1% das calorias diárias ingeridas. Mesmo antes desse marco, diversas abordagens já haviam sido perseguidas por organizações governamentais e de saúde pública em diferentes países para reduzir o consumo desse tipo de gordura. No Brasil, através da resolução no360 da Anvisa de 2003, tornou-se obrigatória a declaração do conteúdo de gordura trans a partir de 2006. Esta dissertação apresenta a evolução e, analisa e avalia os processos regulatórios ligados à redução da gordura trans em alimentos nas experiências da Dinamarca, do Canadá e dos Estados Unidos, identificando as melhores práticas e lições nas experiências destes, contrapondo-as à experiência brasileira. A dissertação conclui destacando o papel da metrologia na qualificação da política pública para saúde, assim como outros aspectos derivados do diagnóstico dos diferentes estudos de caso levados a cabo. O estudo finaliza com a produção de recomendações para o refino e aprimoramento das ações de política pública e da regulação brasileira para a questão. / [en] Trans fats are defined by the Codex Alimentarius as unsaturated fatty acids containing at least a trans double bond. Industrially produced trans fats are formed in the course of the transformation through partial hydrogenation of liquid vegetable oils into semi-solid fats. They are amply used in the production of processed foodstuffs. In 2002, a FAO/WHO report presented convincing proof linking trans fat intake and the risk for developing cardiovascular disease, recommending that its daily consumption should not exceed 1% of total energy intake. Even before this milestone, several approaches had been pursued by government and public health organizations in different countries to reduce trans fat consumption. In Brazil, Anvisa’s 2003 resolution no360 established nutrition labeling of the trans fat content mandatory from 2006. This thesis presents the evolution and analyses and assesses the regulatory processes for reducing trans fats in foodstuffs in Denmark, Canada, and the United States, seeking to identify lessons and best practices in their experiences to contrast with the Brazilian one. The thesis concludes by highlighting the role of metrology in qualifying health policy as well as other aspects derived from the analysis of the case studies. At the end, the study makes some recommendations for refining and improving Brazilian public policy actions and regulation addressing this issue.

[pt] Alguns trabalhos já foram realizados sobre a compra de alimentos por consumidores de baixa renda (Grossi, Motta e Hor-Meyll, 2008; Parente, Barki e Kato, 2005). Entretanto, tais trabalhos foram conduzidos com base em relatos feitos a posteriori pelos consumidores. Este estudo, de caráter exploratório, procurou melhor conhecer o comportamento desses consumidores no ponto de venda. Inicialmente, foi feita observação dos trajetos e comportamentos dos consumidores em mercados localizados em quatro bairros de baixa renda per capita na cidade do Rio de Janeiro. O comportamento dos consumidores, incluindo reações durante a compra, comparações entre opções disponíveis, hesitações, demora para escolher e trocas realizadas, foi observado. Em seguida, esses consumidores foram entrevistados, com temas envolvendo a formulação de sua lista de compras e sobre os comportamentos observados durante a compra. O estudo revelou que, apesar da forte influência que a restrição de renda impõe ao processo de compra de alimentos, outros fatores também parecem ajudar a explicar sua tomada de decisão no ponto de venda. Das observações realizadas e do discurso dos informantes sobressaíram influências ligadas ao ambiente do mercado, à relação dos consumidores com as marcas disponíveis e ao risco percebido por esses consumidores. / [en] Some studies focused on food purchase by low-income consumers have been published in the last years (Grossi, Motta e Hor-Meyll, 2008; Parente, Barki and Kato, 2005). However, these studies were based in data collected after the purchase and provided by consumers. This exploratory study aimed to increase understanding of low-income consumers behavior at the point of sale. Initially, consumer routes and behaviors in four supermarkets located in low-income areas in Rio de Janeiro were observed and noted. Then, those consumers whose purchase paths had been observed answered questions about shopping list formulation, behavior in store, decisions made in store, hesitation in making some choices. The results show that, beside the fact that income constraint played an important role in food purchasing, other factors help to understand decision making in supermarkets by low-income consumers. From observation and interviews emerged influences related to store environment, to how available brands are perceived and to the risk perceived by consumers at the bottom of the economic pyramid.

Thesis presented in partial fulfilment for the degree of Master of Management (in the field of Public and Development Management) to the Faculty of Commerce, Law, and Management, University of the Witwatersrand, 2016 / The research aimed to find out whether one of the unintended outcomes of governments’ top-down implementation of the child support grant was increased fertility among recipients in the rural areas, which generally have higher levels of fertility in the country. South Africa does not have a fertility problem, but development is still much needed in the rural areas. The plight of government, having inherited one of the most unequal society is not minimised. According to Mcnicoll (1998), public transfers among age groups are fertility related. Government directs public expenditures towards social services benefiting the poor. Such expenditures and transfers may significantly modify the economics of fertility as seen by prospective parents. Rural households are more vulnerable because of the economic unviability rooted in the apartheid system. Our study has tried to show how the environment in Lenyenye Township and surrounding villages could make it a possibility for women to see the increment of births as a rational solution for the survival of their family. The theory of bounded rationality was used to demonstrate that rationality is more adaptive to situations based on the environmental constraints. / XL2017
