旅游审美视阈下的江南水乡与岭南水乡之比较

江南水乡与岭南水乡有着"小桥流水人家"的共同点,但两水乡景观的美学意蕴却呈现相异的风格,前者体现出诗意的审美理想,后者却表现为寻常人家的随意、舒适;两个水乡景致在审美动因与审美张力上也各有千秋,引发旅游者不同的审美体验。     

Producing information: communication and collaboration in the South African scientific community

Prior research has investigated the relationships between communication, collaboration and production of information/knowledge. Most of this research has been conducted either in developed countries where the internet facility is highly advanced or in developing countries with little internet access. Investigations in countries that fall in between these two extremes are rare. This study of respondents from higher education institutions and research institutes examines the relationship between collaboration and internet use, as well as productivity and internet use in the South African scientific system which has become a strong contributor to science in Africa.     

Estimating school effectiveness with student growth percentile and gain score models

Measuring school effectiveness using student test scores is controversial and some methods used for this can be inaccurate in some situations. The validity of two statistical models – the Student Growth Percentile (SGP) model and a multilevel gain score model – are evaluated. The SGP model conditions on previous test scores thereby unblocking a backdoor path between true school/teacher effectiveness and student test scores. When the product of the coefficients that make up this unblocked backdoor path is positive, the SGP estimates can be inaccurate. The accuracy of the multilevel gain score model was not associated with the product of this backdoor path. The gain score model appears promising in these situations where the SGP and other covariate adjusted models perform poorly.     

南海地缘形势与中国政府对南海权益的维护——以20世纪六七十年代南海争端为考察中心

20世纪六七十年代,美、前苏联出于争夺世界霸权的需要,对南海争端采取了不同的政策,南海地区＂边缘地带＂特性进一步凸显。在此背景下,菲律宾、越南和马来西亚等国强占南海岛礁、瓜分海域、掠夺资源。在维权斗争中,中国政府不断地进行南海诸岛主权宣示,抗议周边国家对中国海洋国土主权的践踏,收复被占西沙岛礁,并采取切实措施加强海疆国防建设。     

School context and American Indian substance use

The present study extends prior research exploring the role of school contextual factors in predicting individual adolescent substance use by examining how a school’s racial composition is associated with American Indian adolescent tobacco and marijuana use. Using a subsample of 523 American Indian students from the restricted use Add Health data, we consider both individual and school contextual factors across 99 schools. Our results suggest that a school’s racial composition is associated with individual tobacco and marijuana use among American Indian youth, but in different ways depending upon the substance. Our findings illustrate the importance of extending research on the correlates of substance use for racial and ethnic minorities beyond studies examining African-Americans and/or Hispanics.     

South African social workers' knowledge of attachment theory and their perceptions of attachment relationships in foster care supervision

Despite the prominence of attachment theory in international foster care literature and the importance of attachment relationships in successful foster care, attachment theory and practices do not feature prominently in South African foster care research. Against this backdrop, we interviewed twenty South African social workers' about their knowledge of attachment theory and their perceptions of attachment relationships in their own foster care work. Thematic analysis was used to analyse the interviews. We found that the social workers had limited knowledge of attachment theory and interventions; experienced most biological parents as unmotivated to improve their circumstances and attachment relationships with children; indicated that family reunifications were rare occurrences; reported foster parents were mostly kin; and experienced constraining contextual factors that hindered optimal consideration of attachment relationships in foster care supervision.     

The limitations of using school league tables to inform school choice

Summary. In England, so-called 'league tables' based on examination results and test scores are published annually, ostensibly to inform parental choice of secondary schools. A crucial limitation of these tables is that the most recent published information is based on the current performance of a cohort of pupils who entered secondary schools several years earlier, whereas for choosing a school it is the future performance of the current cohort that is of interest. We show that there is substantial uncertainty in predicting such future performance and that incorporating this uncertainty leads to a situation where only a handful of schools' future performances can be separated from both the overall mean and from one another with an acceptable degree of precision. This suggests that school league tables, including value-added tables, have very little to offer as guides to school choice.     

A comparison of social work education across South Africa and Japan in relation to the Global Standards for Social Work Education and Training

Sakaguchi H, Sewpaul V. A comparison of social work education across South Africa and Japan in relation to the Global Standards for Social Work Education and Training Int J Soc Welfare 2011: 20: 192–202 © 2009 The Author(s), International Journal of Social Welfare © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. This article draws on a one‐year study visit to the University of KwaZulu‐Natal, South Africa, interviews with field supervisors and students in Japan and reviews of the national frameworks of education in Japan and in South Africa. In doing so, the authors identify the similarities and differences in social work education across the two countries and they explore some of the historical and socio‐cultural factors that might account for the differences. There are some identifiable peculiarities in social work education in Japan, especially with the coalescing of care work and social work education. The lack of differentiation between care work and social work makes it difficult to narrow the scope of social work education and practice. National social work standards have been approved in South Africa and regulatory frameworks for social work education and practice have been long accepted, thus rendering ‘social work’ a protected title and a profession that is more entrenched compared with social work in Japan. The codes of ethics in Japan and South Africa are discussed with specific reference to their control functions in South Africa. The article concludes by discussing these comparisons in relation to the Global Standards for Social Work Education.

Black men teaching: toward a theory of social isolation in organizations

ABSTRACT

While there continues to be increasing research about Black male teachers’ school-based experiences, there is less empirical evidence on the variation in these experiences for this subgroup. Drawing on Kanter’s Theory of Numbers and Group Composition, the researcher used the qualitative method to compare the perceptions of Black male teachers in schools that employ just one Black male teacher versus schools with larger numbers of Black male teachers. A theory of social isolation in organizations is proposed to explain differences in the variation of school-based experiences for Black male teachers. When compared to Black men in schools with larger percentages of Black male teachers on the faculty, those Black men who were the only Black male teachers on their faculty were more likely to describe feeling socially isolated and disconnected from their colleagues.
