Black Majority Churches (BMC) play a central role in the lives of Black people, informing culture and community. Within the BMC the issues of sexuality and in particular homosexuality are rarely spoken of. However, doctrines in regards to homosexuality have been conveyed in a seemingly homophobic manner, hence individuals experiencing same-sex attraction (SSA) in BMCs have remained silent and unsupported. This phenomenological study explores the lived experiences of five Black Men struggling with SSA and adhering to the teachings of the BMC. The study posed the question, ‘How do Black men struggling with SSA and the teachings of BMCs perceive and describe their lived experiences?’ Data for the study was collected primarily through individual interviews conducted with each participant. The transcripts were analysed using Colazzi’s method for analysing data and two major themes emerged: unfairness and needing support. Discussions of the participants lives indicated that they felt compelled to keep their SSA hidden to avoid stigmatisation, discrimination, isolation and rejection. Moreover, they were also discomforted by the ongoing conflict between their homoerotic feelings and their religious beliefs. Additional data resulting from the questionnaires completed by seventeen Black ministers and leaders of BMCS, provided understanding of the context in which the participants were struggling. The findings suggest that there is a lack of a pastoral care approach for persons experiencing SSA in BMCS and recommends that such an approach is developed. Importantly, this study gives voice to Black men with SSA hurting and hiding in BMCs and has the potential to contribute to the resources required by anyone wanting to find out more about this experience and initiate further research.

This thesis describes a series of empirical studies that investigated the role of apparent health in face preferences. Chapter 1 summarises previous work showing that facial symmetry, averageness and sexual dimorphism influence judgements of facial attractiveness. Chapter 2 describes studies demonstrating that consideration of the role of apparent health in face preferences offers insight into the motivations that underpin attraction to symmetric faces. Chapters 3-5 describe studies demonstrating that, while people generally prefer faces that appear healthy to those that appear unhealthy, characteristics of the judges (e.g. hormonal, health and developmental factors) contribute to systematic variation in women's preferences for apparent health. In the final chapter, a positive link between lifestyle health (e.g. exercise behaviour) and facial health was demonstrated. The findings described in this thesis are evidence that preferences for healthy faces are influenced by biological factors and evidence for accuracy in attributions of health to faces.

abstract: Swarms of animals, fish, birds, locusts etc. are a common occurrence but their coherence and method of organization poses a major question for mathematics and biology.The Vicsek and the Attraction-Repulsion are two models that have been proposed to explain the emergence of collective motion. A major issue for the Vicsek Model is that its particles are not attracted to each other, leaving the swarm with alignment in velocity but without spatial coherence. Restricting the particles to a bounded domain generates global spatial coherence of swarms while maintaining velocity alignment. While individual particles are specularly reflected at the boundary, the swarm as a whole is not. As a result, new dynamical swarming solutions are found. The Attraction-Repulsion Model set with a long-range attraction and short-range repulsion interaction potential typically stabilizes to a well-studied flock steady state solution. The particles for a flock remain spatially coherent but have no spatial bound and explore all space. A bounded domain with specularly reflecting walls traps the particles within a specific region. A fundamental refraction law for a swarm impacting on a planar boundary is derived. The swarm reflection varies from specular for a swarm dominated by kinetic energy to inelastic for a swarm dominated by potential energy. Inelastic collisions lead to alignment with the wall and to damped pulsating oscillations of the swarm. The fundamental refraction law provides a one-dimensional iterative map that allows for a prediction and analysis of the trajectory of the center of mass of a flock in a channel and a square domain. The extension of the wall collisions to a scattering experiment is conducted by setting two identical flocks to collide. The two particle dynamics is studied analytically and shows a transition from scattering: diverging flocks to bound states in the form of oscillations or parallel motions. Numerical studies of collisions of flocks show the same transition where the bound states become either a single translating flock or a rotating (mill). / Dissertation/Thesis / Doctoral Dissertation Applied Mathematics 2015

Magister Artium (Sport, Recreation and Exercise Science) - MA(SRES) / The law of attraction, which is referred to as a pseudo-science by most scientists, focuses on the ability of athletes to reach deep within their soul/ energy sources to re-align their thoughts and feelings in order to achieve their desired outcomes or goals. This study explores whether kickboxers within the African continent are using the phenomenon of the law of attraction in order to enhance their kickboxing performances. In context of law of attraction, kickboxers attract achievements or experiences that they focus on into their life’s, weather these are positive or negative. This means that if they stay focused on the good and positive things in their lives, they will automatically attract good and positive things into their lives. Being part of the cosmic Universe, we are, in our smallest form, nothing but energy with magnetic abilities, hence, we have the ability to attract things or push things away. This belief can contribute to the fulfilment of the desires of kickboxers and can ultimately enhance their sport performances. A qualitative methodology was followed to explore the use of the law of attraction by kickboxers within the sport of kickboxing to achieve optimal results. The population of this study was chosen from kickboxers in countries within the continent of Africa where kickboxing is practiced. These participants were elite athletes (international competitors). A semi-structured interview guide (questionnaire) was used to interview selected kickboxers. Data was recorded and analysed in order to verify the use of the phenomenon of the law of attraction. It was found that most of the participants were unaware that they were utilizing elements of law of attraction and that some elements are intertwined with various sport psychological tools being utilised for sport enhancement. Findings further indicated that the thought process of the participating kickboxers was occupied by various desires or goals that needed to be achieved. The kickboxers found it difficult to prioritize or to streamline their thoughts and this created a situation where energy flowed in the wrong direction. Their feelings in terms of what they thought, what they wanted to achieve and what they could achieve must be in sync. This did not come out strongly because the kickboxers concentrated on their own physical capabilities and kickboxing skills and, at the same time, felt very stressful prior to a kickboxing contest. It was recommended that the phenomenon of law of attraction should be explored more extensively in relation to its application in kickboxing and moreover in sport. It is further recommended that the study be repeated exploring the perspectives of the coaches in the application of law of extraction in their coaching techniques. This study concludes that the law of attraction is not used to its fullest extent in the practice of kickboxing even though some elements were already used by kickboxers.

The attraction effect reveals that people do not compare alternatives independently of one another. Instead, they make comparisons, such that preferences between two alternatives can be reversed by adding or removing otherwise irrelevant alternatives. This behaviour is particularly difficult for rational models of decision making to explain since such models require the independent evaluation of alternatives. As such these models describe preference reversal behaviour as irrational. This thesis examines what rational decision making should look like once a person's cognitive bounds have been taken into account. The key finding is that contextual preference reversals like the attraction effect, far from being irrational, actually result from people making better decisions than they would if they assessed alternatives independently of one another. The research was grouped into three objectives concerning the attraction effect and the rationality of human cognition. The first of these was to identify under what conditions people exhibit the attraction effect, and what consequences the behaviour has for the outcomes they experience. Two experiments revealed that the effect is only exhibited in choice sets where alternatives are approximately equal in value and therefore hard to tell apart. This finding also means that the potential negative consequences of exhibiting the attraction effect are very small, because it only occurs when alternatives are similar in value. The second objective was to develop a computationally rational model of the attraction effect. Computational rationality is an approach that identifies what the optimal behaviour is given the constraints imposed by cognition, and the environment. Our model reveals why people exhibit the attraction effect. With the assumption that people cannot calculate expected value perfectly accurately, the model shows that in choices between prospects, the attraction effect actually results in decisions with a higher expected value. This is because noisy expected value estimates can be improved by taking into account the contextual information provided by the other alternatives in a choice set. The final objective was to provide evidence for our model, and the computational rationality approach, by making a novel prediction. We conducted an experiment to test the model's prediction that the attraction effect should be much reduced in the loss domain. We replicated existing attraction effect studies and extended them to the loss domain. The results replicated previous results in the gain domain and simultaneously revealed the novel finding that people did not exhibit the effect in the loss domain. People exhibit the attraction effect as a result of making the best decision possible given the cognitive resources they have. Understanding decision making as computationally rational can provide deep insights into existing phenomena. The method allows us to ascertain the causal link between cognitive mechanisms, a person's goal, and their decision making.

The LOOK is an iPad-based application that measures sexual interest. It does this by recording the amount of time individuals take to view and rate the attractiveness of images of fully clothed people from differing age, gender, and racial demographics. Viewing-time measures, such as the LOOK, operate under the assumption that individuals view sexually attractive images longer than they view images that they deem unattractive or sexually non-preferred. Although there is research to show the efficacy of these kinds of tests, there is a lack of research supporting the assumption that viewing-time correlates strongly with reported ratings of sexual preferences. This study analyzed existing data from the LOOK to assess the nature of this correlation and how it varies across gender groups. The results of this analysis found that a moderately sized correlation did exist between time spent rating the image (Rate-time) and the subsequent rating of sexual attraction (Ratings) in most age and gender categories. However, for both men and women, these correlations were significantly weaker or were negative in target categories (those categories in which they rated the highest amount of sexual attraction). Additionally, cluster analysis indicated two clusters within both the male and female participant groups that had significantly different mean Rate-time, mean Ratings, and correlation coefficients. Given these results, the viewing-time theory that Rate-time is strongly associated with sexual attraction is questionable. A greater understanding of what viewing-time measures truly assess will require additional research.
