ABSTRACT

Lack of proficiency in writing and research among social work students has increasingly concerned social work educators and practitioners. Given the significance of written communication with clients and emphasis on evidence-based practice in the field of social work, it is critical to assess students’ competence in both writing and research. However, deficit-based approaches to assessing writing and research competence have disadvantaged students at historically black colleges and universities (HBCUs). This pilot study aims to assess writing and research proficiency of HBCU master’s of social work (MSW) students through empirical analysis of their capstone papers and surveys from educators to provide implications for developing a writing and research manual for social work programs at HBCUs. Ten capstone papers were randomly selected and qualitatively analyzed; nine faculty and one field supervisor completed the survey, and their respondents were analyzed using cross-case analysis. Analyses of the capstone papers identified two themes for writing and research domains, respectively: (1) weakness in developing statements and lack of knowledge of writing style and (2) plagiarism and lack of understanding of research structure. Moreover, analyses of the surveys revealed four themes regarding assessment of writing and research skills among students struggling with basic writing mechanics, indicating that HBCU MSW students may have potential and capacity for learning, as evidenced by their ideas and critical thinking skills. These findings suggest both teaching- and research-oriented programs could employ the proposed writing and research assessment manual, as well as a writing and research lab/center for improving writing and research skills among their students.  相似文献

This paper echoes the need to further explore the social effects of European Union integration by examining the increasingly complex and diverse scenario of intra-European mobility. Much research has focused on the intensification of East-to-West migrant flows after the enlargements of 2004 and 2007, inspiring a rich conceptualization of migrant typologies. Theoretically, this paper argues that some of these typologies can be extrapolated to better understand the experiences of other European movers. Empirically, it offers a qualitative and comparative analysis of diverse European young adults’ experiences of mobility: 8 Polish citizens in The Hague and 10 Spaniards in London. The analysis is based on four main dimensions derived from the literature: (1) Motivations to migrate, (2) Labour market participation, (3) Attachments and transnational ties and (4) Family composition and future outlooks. Results map individual differences and similarities contextualized by generational, gendered, educational and socio-economic aspects.  相似文献

The purpose of this study is to explore intersections between religion, faith and social identity with regards to their impact on either promoting or preventing sport participation amongst self-identified British Asian Muslim males living in Birmingham (West Midlands of the UK) aged 16–25 years old. The research questions around this topic of study are to explore how interpretations of Islamic faith promote or prevent sport participation amongst young Muslim males. Secondly, the paper will examine the perspectives of Muslim male participants in relation to sport to identify factors determining sport participation. Finally, the study will consider implications for policy and practice in sport development. The study drew upon seven in-depth, semi-structured interviews with Muslim males aged 16–25 years old and applied a thematic analysis and coding methodology to unpick the key dimensions and findings from the data. Findings from the study indicate the complexity of young Muslim male sport participation contexts, dynamics in decision-making, family influence and perceptions held about other communities and their own. The study draws out key implications for agencies in sport development that seek to encourage sport participation cutting across school, community, local government and national governing body partnerships specifically considering Islamic faith communities.  相似文献

Erectile dysfunction (ED) is one of the most common disorders in male and is often associated with other age-related comorbidities. The aging process affects the structural organization and function of penile erectile components such as smooth muscle cell and vascular architecture. These modifications affect penile hemodynamics by impairing cavernosal smooth muscle cell relaxation, reducing penile elasticity, compliance and promoting fibrosis. This review aims to identify the mechanisms of ED in the penile aging process in experimental and clinical data. It also highlights areas that are in need of more research. The search strategies yielded total records screened from PubMed. Clarification of the molecular mechanisms that accompanies corpus cavernosum aging and aging-associated ED will aid new perspectives in the development of novel mechanism-based therapeutic approaches. Age is not a limiting factor for ED medical management, and it is never too late to treat. Hypogonadism should be managed regardless of age, and synergistic effects have been found during testosterone (T) replacement therapy when used along with oral phosphodiesterase-5 (PDE-5) inhibitors. Therefore, the clinical management of ED related to aging can be done by therapeutic interventions that include PDE-5 inhibitors, and other pharmacological treatments.  相似文献

As social movements relying on the weak ties found in social networks have spread around the world, researchers have taken several approaches to understanding how networks function in such instances as the Arab Spring. While social scientists have primarily relied on survey or content analysis methodology, network scientists have used social network analysis. This research combines content analysis with the automated techniques of network analysis to determine the roles played by those using Twitter to communicate during the Turkish Gezi Park uprising. Based on a network analysis of nearly 2.4 million tweets and a content analysis of a subset of 5126 of those tweets, we found that information sharing was by far the most common use of the tweets and retweets, while tweets that indicated leadership of the movement constituted a small percentage of the overall number of tweets. Using automated techniques, we experimented with coded variables from content analysis to compute the most discriminative tokens and to predict values for each variable using only textual information. We achieved 0.61 precision on identifying types of shared information. Our results on detecting the position of user in the protest and purpose of the tweets achieved 0.42 and 0.33 precision, respectively, illustrating the necessity of user cooperation and the shortcomings of automated techniques. Based on annotated values of user tweets, we computed similarities between users considering their information production and consumption. User similarities are used to compute clusters of individuals with similar behaviors, and we interpreted average activities for those groups.  相似文献

Many governments, in their zeal to progress and deliver the fruits of development, are caught in a web of unsavory habits and practices that impair not only their international image but also domestic legitimacy. One such perennially persistent and resilient disease is ‘money politics.’ Taking Malaysia as a case study, we note that despite sustaining a remarkable record of economic and multiethnic stability, the country has also been helpless in mitigating this obstinate issue. In this article, it is posited that the phenomenon is not a new or recent portent but has actually persisted even prior to independence. We shall then contend that unless the ruling Barisan Nasional (BN) coalition government attaches greater priority in stamping out this political bug, the country’s otherwise enviable development trajectory and the quest to reach a ‘developed nation’ status via its Vision 2020 declaration, even if fulfilled, are not cause for celebration, given its implications to the country’s economic sustainability and multiethnic stability.  相似文献

In this article, I focus on the management of postcolonial difference and the production of belonging in a white settler nation-state in order to rethink the notion of co-optation. I first develop a theoretical framework for understanding co-optation by separating the “who” and the “what” of co-optation: actors who embody diversity in public, political debate become the “who” of co-optation, as their agency is shaped by gendered and racialized processes of subject making. The “what” of co-optation revolves around particular conceptualizations of practices, rights and freedoms, associated in this case with “gender equality,” which is rendered an empty signifier in the process. I then illustrate this framework by drawing from research on the Sharia-based arbitration debate that took place in Ontario, Canada, between late 2003 and early 2006. I focus on the claims of two Canadian Muslim women activists to show that co-optation occurs as attempts to further liberation instead advance illiberal practices.  相似文献

The duration of children's attention to putative threat has been documented as a consistent predictor of later anxiety in inhibited children across childhood (Fox, New Directions for Child and Adolescent Development, 127, 2010, 33; Pérez‐Edgar & Fox, Child and Adolescent Psychiatric Clinics of North America, 14, 2005, 681). However, attention to threat has not been broadly examined within existing behavioral contexts and has seldom been studied in very early childhood. Whereas toddlers with high levels of internalizing behavior may view fear‐inducing stimuli as a threat, toddlers with high levels of externalizing behavior may demonstrate attention out of interest or sensation seeking. Thus, attention to threat was expected to predict increased toddler shyness in the context of either high internalizing problems or low externalizing behavior. We examined 117 twenty‐four‐month‐old toddlers to determine whether attention to threat interacted with internalizing and externalizing behavior at 24 months of age to predict toddler shyness one year later. Results indicated that attention to threat predicted toddlers' lower shyness at 36 months when toddlers’ externalizing behavior at age 24 months were high, but there was no significant interaction between toddlers’ internalizing behavior and their attention to threat in predicting later shyness. These results expand our understanding of the contexts in which attention to threat in early childhood is a viable predictor of later shyness.  相似文献

This essay begins by questioning the role that the word “boundary” plays when we say that a “sexual boundary violation” has occurred in an analytic treatment. Boundaries are bright lines drawn to separate lawful from unlawful, consensual from coerced, free from exploited, ownership from trespass, fantasy from reality. But the notion of boundaries fails in a profound and fateful way to capture the inescapable circulation of erotic transference and countertransference feelings in an analysis. Instead, this essay proposes that we look to the notion of sublimation for insights into the psychic dynamics of sexual behavior between analyst and analysand. It explores the ambivalence and mourning that surround the sublimation of desire. This discussion of sublimation sheds light on sexual violations in other types of professional relationships as well as recently adopted affirmative consent laws and policies on college campuses.  相似文献
