This article is a reflection on the teaching of black history after the Obama presidency and at the dawn of the Trump era. It is both an analysis of the state of the academic field and a primer on how to integrate the past few decades of scholarship in black history broadly across standard K-12 curriculum. It demonstrates the importance of theorizing black history as American history rather than just including African American content in US History courses and offers specific methods that can shift the narrative in this direction even within the confines of a more traditional telling of the American past. Finally, it situates the voluminous work of historians of the black past as critical interventions in pedagogy necessary to challenge today's unrelenting attacks on public education.  相似文献

The United Nations Millennium Development Goals (MDGs) are unlikely to be achieved by 2015, owing to conceptual flaws in their design as well as the structural and political constraints faced during implementation at the country level. While criticism of the MDGs is widespread, innovative ideas on addressing these operational challenges are still scanty. By reviewing a number of experiences, including those of the Foundation for the Promotion of Local Development (PRODEL) in Nicaragua and the Ministry of Cities in Brazil, this article highlights the importance of incorporating an asset‐accumulation perspective into MDG‐related policies and programmes as a way of generating an enabling environment that opens up new opportunities for poverty reduction in the cities of low‐ and middle‐low‐income countries.  相似文献

In an interview with Dr. Lawrence Shulman, he presents his insights on clinical supervision from a social work and interdisciplinary perspective. Dr. Shulman is a luminary in social work and interdisciplinary supervision, developing the Interactional Model of Supervision. In reflecting on his career in social work research, education, and practice, he shares his thoughts regarding the importance of process-oriented supervision as a needed focus for research and practice. Supportive of integrating art and science in social work practice, he offers his perspectives on the current state of supervision in the evidence-based era.  相似文献

This paper discusses some current issues in relation to doctoral studies in social work in the UK. It draws on recent research and other sources to illustrate that our knowledge about the scope and scale of such doctoral work is limited. However, developments within the discipline and the wider policy and institutional context of professional education suggest that research (in general) has an increasing profile. This trend, together with debates about focus and research approaches in social work, has implications for the possible extension of opportunities for doctoral studies. It is further suggested that 'professional doctorate' programmes or 'PhD by publication' routes may be more suited to the needs of doctoral students in social work, given different career paths relative to students in some other disciplines.  相似文献

This article analyses the social aesthetic of the visual displays of a multicultural London primary school. It shows that the social aesthetic of the school models the school as a site of the ‘real’ in Baudrillard's sense of a ‘real’ that is a simulacra of the real, one from which the violence that is produced within and is constitutive of capitalism is expelled. In this view ‘race’ is not a division of humanity caused by racism, it is simply a cultural sign marking diversity. Difference, in the sense of racialised inequalities or racism, can be expelled from the system without ‘race’ itself being expelled. By the same logic, nationalism, as an exclusionary ideology, is separated out from national identity, which becomes simply one of a range of cultural resources that children can draw on in assembling the self.  相似文献

Online material and waste exchanges (OMWEs) provide online channels to repurpose by‐products, unused materials and waste from industrial and commercial facilities. Unfortunately, OMWE's also have challenges. First, sellers may have access to other disposal options and, as a result, may not fully commit to the exchange. Second, buyers can face high uncertainty about the product exchanged and the transaction being undertaken. Overcoming these challenges is the “last hurdle” to making OMWEs successful. This study investigates the factors that reduce the buyers' uncertainty and increase the sellers' commitment to the OMWE. We analyze novel transaction‐level data from an online exchange (MNExchange.org) combined with other archival public records on county‐level repurposing and disposal statistics. First, we find that regional repurposing policies and alternatives have a complementary effect on sellers' commitment toward OMWEs, resulting in increased OMWE exchanges. However, regional disposal policies and alternatives have a substitution effect on sellers' commitment, resulting in reduced exchange success. Further, greater product and transaction information reduce the buyer's uncertainty and increase exchange success. Finally, the analysis shows that users' (buyers and sellers) heavily rely on their prior experience with OMWEs. Specifically, higher familiarity between the buyer–seller pair and familiarity with the OMWE system leads to higher likelihood of exchange success. This study lays the foundation for understanding OMWEs and has important implications for developing policies and operations to increase online transactions of by‐products, materials and wastes.  相似文献

In current industry practice, it is difficult to assess QT effects at potential therapeutic doses based on Phase I dose‐escalation trials in oncology due to data scarcity, particularly in combinations trials. In this paper, we propose to use dose‐concentration and concentration‐QT models jointly to model the exposures and effects of multiple drugs in combination. The fitted models then can be used to make early predictions for QT prolongation to aid choosing recommended dose combinations for further investigation. The models consider potential correlation between concentrations of test drugs and potential drug–drug interactions at PK and QT levels. In addition, this approach allows for the assessment of the probability of QT prolongation exceeding given thresholds of clinical significance. The performance of this approach was examined via simulation under practical scenarios for dose‐escalation trials for a combination of two drugs. The simulation results show that invaluable information of QT effects at therapeutic dose combinations can be gained by the proposed approaches. Early detection of dose combinations with substantial QT prolongation is evaluated effectively through the CIs of the predicted peak QT prolongation at each dose combination. Furthermore, the probability of QT prolongation exceeding a certain threshold is also computed to support early detection of safety signals while accounting for uncertainty associated with data from Phase I studies. While the prediction of QT effects is sensitive to the dose escalation process, the sensitivity and limited sample size should be considered when providing support to the decision‐making process for further developing certain dose combinations.

The assessment of malingering has predominantly been considered within the domains of neuropsychologists and psychiatrists, who use consistency of performance criteria similar to those used in functional capacity evaluations (FCE). The use of activity has traditionally been used in occupational therapy as an assessment and treatment modality with goals not always considered obvious and which could easily be used for diversional reasons. The appropriate use of activity adds an additional dimension to a layered approach of using multiple data sources and methods as recommended by FCE practitioners and neuropsychologists alike. The case illustration aims to explain the above using a layered model.  相似文献
