Cancrinella and Costatumulus (Brachiopoda) from the Permian of South Mongolia and South China : their morphology, biostratigraphy and distribution

Two brachiopod genera, Cancrinella Fredericks and Costatumulus Waterhouse, are studied from the Permian of South Mongolia and South China. Many of the specimens previously described as Cancrinella are revised and assigned to Costatumulus. The new data presented in this paper indicate that these two genera are similar to each other, but are distinguishable by different features in relation to their morphology. Several species of both genera are described here, providing critical new information on the morphology and taxonomy of Cancrinella and Costatumulus. The reported biostratigraphical information reveals that species of Cancrinella are present from the Lower Carboniferous (Tournaisian) to Middle Permian (Capitanian), whereas species of Costatumulus are mostly restricted to the Lower Permian (Sakmarian) to Upper Permian (Changhsingian). An analysis of the palaeogeographical distribution of Cancrinella and Costatumulus reveals that Cancrinella was more commonly distributed in the Northern Transitional Zone and the Boreal Realm, in contrast to Costatumulus, which tended to be more common in the Southern Transitional Zone and Gondwanan Realm.

Board diversity or gender diversity? Perspectives from Europe, Australia and South Africa

Board diversity has been a hot topic for several years. However, it is only in recent years that pertinent questions have been asked about what is actually meant by board diversity and what would constitute a board with an ideal diversity. In the past the debate on board diversity has always been dominated by the lack, or very low numbers, of females on boards. This has been a fact in most countries with sophisticated corporate law and corporate governance systems in place. The issue of female representation on boards still dominates the board diversity debate, but other forms of diversity, including age, cultural, nationality and race have also become part of the debate. The quest is to find answers to questions like whether a diversified board would be better, and whether diversified boards will ensure a better return for investors; in other words, whether there is a ‘business case’ to be made out to have diversity on a board. Many studies have been done, but the answer is still evasive. This is not totally unexpected as the criteria used for these studies differ and the circumstances and complexities of business are such that a final conclusion will probably never be reached. In this article we focus on the board diversity debate in Europe, Australia and South Africa – three completely different parts of the world. In addition we devote Part V to put the topic of board diversity in a broader context, but paying particular attention to gender diversity.

Demographic and socio-cultural correlates of medical mistrust in two Australian states:Victoria and South Australia

Studies on medical mistrust have mainly focused on depicting the association between medical mistrust and access/utilization of healthcare services. The effect of broader socio-demographic and psycho-social factors on medical mistrust remains poorly documented. The study examined the effect of broader socio-demographic factors, acculturation, and discrimination on medical mistrust among 425 African migrants living in Victoria and South Australia, Australia. After adjusting for socio-demographic factors, low medical mistrust scores (i.e., more trusting of the system) were associated with refugee (β=−4.27, p<0.01) and family reunion (β=−4.01, p<0.01) migration statuses, being Christian (β=−2.21, p<0.001), and living in rural or village areas prior to migration (β=−2.09, p<0.05). Medical mistrust did not vary by the type of acculturation, but was positively related to perceived personal (β=0.43, p<0.001) and societal (β=0.38, p<0.001) discrimination. In order to reduce inequalities in healthcare access and utilisation and health outcomes, programs to enhance trust in the medical system among African migrants and to address discrimination within the community are needed.

Tertiary educators' voices in Australia and South Africa: experiencing and engaging in African music and culture

Music tertiary educators can foster positive experiences that promote diversity, enhance intercultural and cross-cultural understanding through our teaching. Through findings of interview data of tertiary music educators’ understandings of multicultural music practice at two South African universities and at an Australia university, I used interpretative phenomenological analysis to analyse the data. Two major themes emerged: why is it important to teach multicultural music like that of Africa, and what are some of the effective ways of preparing students to best teach it? The data provides insights into an appreciation of and respect for music and cultural diversity. In multicultural societies educators cannot deliver courses based solely on one’s own identity and cultural perspective. I argue that music education may be seen as an agent of social change where music teaching and learning can occur through exploring, experiencing, expressing and engaging in the music of our own culture and that of others.

Reconciliation and the Goguryeo/ Gāogōulì disputes between China and South Korea

Just as the failure to reconcile views of the past and to address historical injustice has damaged inter-state relations in East Asia, the Goguryeo/Gāogōulì dispute has harmed relations between South Korea and China. In this chapter, we provide a detailed analysis of the dispute, and explore how this contestation has been reconciled through elite settlement, UNESCO's arbitration and the idea of shared history.

Social network analysis and small group ‘dark’ networks: an analysis of the London bombers and the problem of ‘fuzzy’ boundaries

Social network analysis (SNA) is believed to be capable of revealing significant insights into crime and terror groups, including identifying important individuals and unique approaches to disruption. However, SNA has a number of theoretical and practical limitations, particularly when applied to ‘dark’ networks. While most analysts certainly acknowledge at least some of these limitations, we need to know more about their potential impact in a crime intelligence context. This article aims to go some way towards that end by placing greater scrutiny on the problem of ‘fuzzy boundaries’ when applied to small group networks. SNA is applied to the groups responsible for the 7 July 2005 London bombings and the 21 July 2005 attempted London bombings. The article concludes that while SNA is a valuable tool for understanding crime and terror groups, the age-old problem of fuzzy boundaries can have a profound impact on the analysis of small dynamic networks.

Establishing insurance markets in settler economies. a comparison of Australian and South Africa insurance markets, 1820-1910

How did insurance markets in the settler economies of Australia and South Africa develop? This paper investigates the establishment of the local insurance industries in two settler economies in the wake of the absence of comparative studies in the emergence of insurance markets in the periphery. The paper compares conditions in these settler economies and notes the innovative role of local entrepreneurs. British insurance companies extended operations into the British colonies, but local interests emerged to challenge their dominance. Innovations in organisational form, product offerings and distribution channels afforded local entrepreneurs a competitive advantage in the life market. Collusion in the fire market restricted innovative practices and retained foreign control. This article explains the agency of local entrepreneurs in the emergence of insurance markets in two settler societies at the end of the nineteenth century. This historical development path has notable implications for the current development of insurance markets in Africa.

Comparative Analysis of Adolescent Pregnancy in Central America, Mexico and South Carolina

This paper addresses the issue of adolescent pregnancy in Mexico, Central America and South Carolina and implications for social work practice with immigrant communities. The paper is based on current literature and on cross-national, on-line survey of local and international pregnancy prevention programs. The paper analyzes and discusses various psychosocial causes of pregnancy in adolescents, including: limited opportunities for formal education, infrequent open discussions about sexual health, rising costs of adequate birth control, and difficulty in obtaining contraceptives in remote locations. This research paper analyzes current statistics on the effectiveness of existing projects and programs and compares and contrasts research about the validity and efficacy of these programs in both South Carolina and abroad. Finally, the paper addresses implications for social work practice with adolescents in immigrant communities.
