Philanthropy and Equity: The Case of South Africa

This paper explores the potential role for philanthropy to promote greater equity in South Africa. It also aims to stimulate further discussion and debate about how philanthropic resources can best contribute to a more just and equitable South Africa, and encourage others engaged in philanthropy elsewhere in the world to reflect on South Africa's experience

A Survey of the Management and Development of Captive African Elephant (\u3cem\u3eLoxodonta africana\u3c/em\u3e) Calves: Birth to Three Months of Age

We used four surveys to collect information about the birth, physical growth, and behavioral development of 12 African elephant calves born in captivity. The management of the birth process and neonatal care involved a variety of standard procedures. All of the calves were born at night, between 7PM and 7AM. The calves showed a systematic progression in behavioral and physical development, attaining developmental milestones at least a quickly as calves in situ. This study emphasized birth-related events, changes in the ways that calves used their trunks, first instances of behaviors, and interactions of the calves with other, usually adult, elephants. Several behaviors, such as the dam covering her calf with hay and the calf sucking its own trunk, were common in the captive situation and have been observed in situ. Overall, the behaviors of the calves resembled those observed for African elephant calves in situ. These data should help in the management of African elephants under human care by providing systematic reference values for the birth and development of elephant calves

Employment equity in Canada and South Africa: a comparative review

The South African Government has sought to redress the historical legacy of workplace discrimination by introducing the Employment Equity Act (1998), which was largely modeled on the Canadian Employment Equity Act. Although there is very little comparative information between South Africa and Canada, we fill this gap by reviewing the literature in both countries, highlighting common features of the legislation, discussing the effectiveness of legislation in both countries as well as the progress made by the designated groups covered by the legislation. This paper provides a background on the rationale for employment equity and associated human resource management policies in both Canada and South Africa. The analysis is largely based on institutional theories of organizations. Our evaluation provides overall conclusions for policy makers and organizational leaders, taking into consideration socio-historical, political, and demographic differences between the jurisdictions. Issues include top management commitment, organizational culture, Black economic empowerment, and diversity policies and practice

Control of lipid organization and actin assembly during clathrin-mediated endocytosis by the cytoplasmic tail of the rhomboid protein Rbd2.

Clathrin-mediated endocytosis (CME) is facilitated by a precisely regulated burst of actin assembly. PtdIns(4,5)P2 is an important signaling lipid with conserved roles in CME and actin assembly regulation. Rhomboid family multipass transmembrane proteins regulate diverse cellular processes; however, rhomboid-mediated CME regulation has not been described. We report that yeast lacking the rhomboid protein Rbd2 exhibit accelerated endocytic-site dynamics and premature actin assembly during CME through a PtdIns(4,5)P2-dependent mechanism. Combined genetic and biochemical studies showed that the cytoplasmic tail of Rbd2 binds directly to PtdIns(4,5)P2 and is sufficient for Rbd2's role in actin regulation. Analysis of an Rbd2 mutant with diminished PtdIns(4,5)P2-binding capacity indicates that this interaction is necessary for the temporal regulation of actin assembly during CME. The cytoplasmic tail of Rbd2 appears to modulate PtdIns(4,5)P2 distribution on the cell cortex. The syndapin-like F-BAR protein Bzz1 functions in a pathway with Rbd2 to control the timing of type 1 myosin recruitment and actin polymerization onset during CME. This work reveals that the previously unstudied rhomboid protein Rbd2 functions in vivo at the nexus of three highly conserved processes: lipid regulation, endocytic regulation, and cytoskeletal function

Do Students Who Have Greater Parental Involvement Perform Better Academically Than Students With Less Parental Involvement?

Parental involvement is a significant factor in increasing student achievement. The participants were twenty-one first grade students during the 2006-2007 school term at a Title I school located in middle Georgia. A parent survey using a Likert-type scale was used to measure parental involvement within the home setting. Student performance was measured by using the scores from graded homework as well as the results of reading, math, and sight word pretests and post tests. There was a moderate positive correlation between the results of the parent survey and the student performance scores. One hundred percent of the parents responded that they were involved with their children at home on the survey. This study found that increased involvement indeed makes a difference in a child’s academic performance

The Cultural Competence of Response & Recovery Workers in Post-Earthquake Haiti

Cultural competence is critical to public service, yet it is often ignored and underutilized, especially in post-disaster response and recovery. The current literature on cultural competence and frameworks developed by the private sector do not fully consider the complexities of a post-disaster public service context. This project explores the importance of cultural competence in post-disaster response and recovery, identifies effective training methods and organizational policies which may present barriers to competence acquisition, and proposes a new theoretical framework by which to assess cultural competence in international response and recovery work. This study used focus groups with Haitian beneficiaries (n=7), in-depth interviews with response and recovery workers (n=50), close ended surveys with both groups (n=226), observation, and a review of secondary sources (e.g. job announcements, training manuals) to explore cultural competence from the perspectives of international response and recovery workers, their agencies, and Haitian beneficiaries after the January 2010 Haitian earthquake. The analysis revealed that although 88% of participating aid workers identified cultural competence (CC) as critical to program effectiveness, 42% had no training before or during deployment. An analysis of the job announcements revealed that only 37% of agencies required cultural competencies. While aid workers and beneficiaries identified experiential strategies (e.g. immersion, mentoring) as critical to cultural competence acquisition, organizational policies (e.g. curfews, restrictions on travel) were often found to be at odds with these methods and more than 1/3 of participating aid workers felt that these policies were a barrier to cultural competency. Findings from this study may help aid workers better understand the importance of cultural competence and how it can improve the effectiveness of aid programs, and provide ways in which aid agencies can enhance cultural competence acquisition by their employees

Dust Destruction Rates and Lifetimes in the Magellanic Clouds

The nature, composition, abundance, and size distribution of dust in galaxies is determined by the rate at which it is created in the different stellar sources and destroyed by interstellar shocks. Because of their extensive wavelength coverage, proximity, and nearly face-on geometry, the Magellanic Clouds (MCs) provide a unique opportunity to study these processes in great detail. In this paper we use the complete sample of supernova remnants (SNRs) in the MCs to calculate the lifetime and destruction efficiencies of silicate and carbon dust in these galaxies. We find dust lifetimes of 22 +- 13 Myr (30 +- 17 Myr) for silicate (carbon) grains in the LMC, and 54 +- 32 Myr (72 +- 43 Myr) for silicate (carbon) grains in the SMC. The significantly shorter lifetimes in the MCs, as compared to the Milky Way, are explained as the combined effect of their lower total dust mass, and the fact that the dust-destroying isolated SNe in the MCs seem to be preferentially occurring in regions with higher than average dust-to-gas (D2G) mass ratios. We also calculate the supernova rate and the current star formation rate in the MCs, and use them to derive maximum dust injection rates by asymptotic giant branch stars and core collapse supernovae. We find that the injection rates are an order of magnitude lower than the dust destruction rates by the SNRs. This supports the conclusion that, unless the dust destruction rates have been considerably overestimated, most of the dust must be reconstituted from surviving grains in dense molecular clouds. More generally, we also discuss the dependence of the dust destruction rate on the local D2G mass ratio, the ambient gas density and metallicity, as well as the application of our results to other galaxies and dust evolution models.Comment: 15 pages, 8 figures, 5 tables, accepted to Ap
