Sovereignty and resistance : India, China and the Asian-African Conference, 1955

This thesis examines the Asian-African Conference at Bandung, Indonesia in 1955 from a broad historical perspective. It presents evidence that the assertion of independent Asian foreign policy - non-aligned and communist led by India and China - signalled a more significant, long-term shift in West-East realtions than has been previously identified.

Coping under pressure : strategies for maintaining confidence amongst South African soccer coaches

Sport coaching can be a fulfilling and rewarding occupation, but can also be stressful because of the demands and expectations of various external factors. The complex and extraordinary demands placed on coaches, force them to perform multiple roles (e.g. educator, motivator, counsellor, adviser, trainer, manager and administrator). Soccer coaches face a number of challenges, frustrations, conflicts and tensions, the enormity of which is often underestimated. This notion is supported by the description of coaching as a perilous occupation in which coaches experience pressures like stress, conflict and tension, media pressure and intrusions into family life. This study explored the perceptions of South African soccer coaches in terms of the mechanisms they use to cope with potential stressors experienced in their jobs and employed a non-experimental design, using a quantitative approach, to assess stress and coping strategies of South African coaches. One hundred and twelve soccer coaches, coaching at the provincial level and higher, completed a questionnaire on stress and stress coping mechanisms used in their coaching jobs. Descriptive data analysis was completed using the Statistical Package for Social Sciences (SPSS – version 16). The sources of stress experienced and coping methods used by the coaches were evaluated. Results revealed that the top three sources of stress were a lack of resources, fixture backlog and games where the outcome is critical, whilst the lowest three sources of stress were political interference, physical assaults from players and substituting a player. Moreover, various coping strategies used by the coaches showed that an average of 5.68%, 5.14% and 89.78% of the sample used maladaptive coping, emotion management coping and problem management coping strategies respectively. Academic and practical implications of the study results are discussed.

The impact of a parenting intervention in Australia among migrants and refugees from Liberia, Sierra Leone, Congo, and Burundi : results from the African migrant parenting program

African migrants and refugee families who resettle in high-income countries such as Australia face many challenges. Negotiating parenting in a new culture is one of the most pressing challenges that is faced by most African migrant and refugee parents. As a consequence of the new cultural environment reflecting values and practices that may seem inconsistent with traditional parenting from countries of origin, differing acculturation rates of parents as compared to their children may lead to difficulties and challenges. An eight-session parenting program for African migrant and refugee parents living in Melbourne was evaluated. Thirty-nine families participated in the program, which involved pre-test and post-test measures of parenting domains, using the Bavolek and Keene (1999) revised Adult–Adolescent Parenting Inventory (AAPI-2). Exposure to the program was related to positive changes in parental expectations of children, attitudes towards corporal punishment, and restriction of children’s access to food. The program facilitated positive change in almost all parenting domains. In light of these findings, recommendations are made for policy and future programs.

Barriers to blood donation in African communities in Australia: the role of home and host country culture and experience

BACKGROUND: An influx of African migrants and refugees can strain a host country's blood services, because often migrants have unique blood needs that cannot be sourced from local donors. To increase blood donation by the new migrants, host country blood services need to understand how blood and blood donations are viewed by immigrant communities, because recruitment models that are not culturally adapted may have limited success.

STUDY DESIGN AND METHODS: Nine focus groups representing a cross-section of Australian-based African communities were conducted in multiple languages, facilitated by bilingual workers. The qualitative protocol was guided by the literature on blood donation by African migrants and communities in Africa. Thematic analysis identified the relevance of issues previously included in the literature and whether other issues facilitated or prohibited blood donation.

RESULTS: Home country cultural issues were not generally raised as barriers to donation, and respondents were positively disposed toward donation. Home country experiences shaped respondents' views in Australia. Participants focused on assisting “individuals in need,” rather than giving to a blood service that many viewed with suspicion because of issues in their home country. There was a lack of knowledge about the donation process in Australia. More importantly, respondents perceived that their blood would not be wanted, based on a perception of host country mistrust and discrimination.

CONCLUSION: Developing an intervention that encourages migrants to donate blood needs to be culturally focused. It appears that addressing perceptions based on home country experiences is essential. Overcoming a general perception of discrimination is beyond any blood service, but there can be an attempt to ensure that blood donation is seen as an inclusive process—blood from everyone, for everyone.

Power, influence and intranet implementation : a safari of South African organizations

Intranets hold great promise as ``organizational Internets'' to allow information sharing and collaboration across departments, functions and different information systems within an organization. Yet not much is known about how to implement intranets. We adapt a taxonomy based on institutional theory and distinguish six broad diffusion drivers that might be considered to sustain the implementation process. An exploratory field study of four intranet implementations was conducted to analyze which drivers were used and the results that were yielded. We draw several conclusions. First, all six drivers were deployed in the analyzed cases. Second, the choice of drivers varied with the level of the intranet (corporate or unit), the implementation stage, and existing organizational practices and contingencies. Third, it seems that the critical drivers are knowledge building, subsidy and mobilization in the early stages of implementation. In the later stages knowledge deployment, subsidy and innovation directives were most commonly used.

Prevalence of vitamin D insufficiency and risk factors for type 2 diabetes and cardiovascular disease among African migrant and refugee adults in Melbourne

Migration to industrialised countries poses a “double whammy” for type 2 diabetes among sub-Saharan African migrant and refugee adults. This population group has been found to be at an increased risk of obesity and type 2 diabetes, which may be further aggravated by inadequate vitamin D status. Thus, this study aimed to describe the demographics of vitamin D insufficiency, obesity, and risk factors for type 2 diabetes among sub-Saharan African migrants and refugees aged 20 years or older living in Melbourne, Australia (n=49). Data were obtained by a questionnaire, medical assessment, and fasting blood samples. The mean serum 25-hydroxyvitamin D level was 27.3 nmol/L (95% CI: 22.2, 32.4 nmol/L); with 25-hydroxyvitamin D levels <50 nmol/L occurring in 88% of participants. Participants displayed a cluster of risk factors for type 2 diabetes and cardiovascular disease: 62% were overweight or obese, 47% had insulin resistance (HOMA-IR ≥2), 25% had low density lipoprotein cholesterol levels ≥3.5 mmol/L, 24.5% had high density lipoprotein cholesterol levels ≤1.03 mmol/L, 34.6% had borderline or high levels of total cholesterol (≥5.2 mmol/L), 18.2% had borderline or high levels of triglyceride (≥1.7 mmol/L), and 16% had hypertension (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg). These findings suggest that sub-Saharan African migrants and refugees may be at risk of type 2 diabetes and atherosclerosis-related diseases such as ischemic heart disease, stroke, and peripheral vascular disease. Well-designed vitamin D interventions that incorporate lifestyle changes are urgently needed in this sub-population.

Simulating crowd phenomena in African markets

Crowd simulation is an important feature in the computer graphics field. Typical implementations simulate battle scenes, emergency situations, safety issues or add content to virtual environments. The problem stated in this paper falls in the last category. We present a crowd simulation behavioural model which allows us to simulate identified phenomena in popular local African markets such as narrow street flows and crowd formation around street performances. We propose a three-tier architecture model enable to produce intentions, perform path planning and control movement. We demonstrate that this approach produces the desired behaviour associated with crowds in an African market, which includes navigation, flow formation and circle creation.

Modelling and rendering techniques for African hairstyles

We develop or enhance hair modelling and rendering techniques to produce three different forms of hair commonly found in African hairstyles. The forms of hair are natural curly hair, straightened hair, and braids or twists of hair.

We use an implicit model, implemented as a series of textured layers to represent curly hair. Straightened hair is represented explicitly, and modelled by defining and replicating a few control hairs. Braids and twists are implemented as textured generalized cylinders.

A synthesis of existing hair illumination models is used as a basis for an African hair illumination model. Parameter values to match African hair characteristics are discussed.

A number of complete African hairstyles are shown, demonstrating that the techniques can be used to model and render African hair successfully.

Duplicating road patterns in South African informal settlements using procedural techniques

The formation of informal settlements in and around urban complexes has largely been ignored in the context of procedural city modeling. However, many cities in South Africa and globally can attest to the presence of such settlements. This paper analyses the phenomenon of informal settlements from a procedural modeling perspective. Aerial photography from two South African urban complexes, namely Johannesburg and Cape Town is used as a basis for the extraction of various features that distinguish different types of settlements. In particular, the road patterns which have formed within such settlements are analysed, and various procedural techniques proposed (including Voronoi diagrams, subdivision and L-systems) to replicate the identified features. A qualitative assessment of the procedural techniques is provided, and the most suitable combination of techniques identified for unstructured and structured settlements. In particular it is found that a combination of Voronoi diagrams and subdivision provides the closest match to unstructured informal settlements. A combination of L-systems, Voronoi diagrams and subdivision is found to produce the closest pattern to a structured informal settlement.
