This paper reports on the developmental strategies, challenges and directions of the institutional repositories of the higher educational institutions in Hong Kong. The study integrates the size, content, full text and public accessibility of these repositories. The paper also compares archived output with research output as registered by the Hong Kong University Grants Committee. Percentages of archived work are low for journal and conference papers, but moderate for graduate theses. These deposit rates reflect the differing institutional policies. In recognizing these challenges, the Hong Kong Open Access Committee has been formed to address regional issues in knowledge sharing.  相似文献

Randomized response techniques are widely employed in surveys dealing with sensitive questions to ensure interviewee anonymity and reduce nonrespondents rates and biased responses. Since Warner’s (J Am Stat Assoc 60:63–69, 1965) pioneering work, many ingenious devices have been suggested to increase respondent’s privacy protection and to better estimate the proportion of people, π A , bearing a sensitive attribute. In spite of the massive use of auxiliary information in the estimation of non-sensitive parameters, very few attempts have been made to improve randomization strategy performance when auxiliary variables are available. Moving from Zaizai’s (Model Assist Stat Appl 1:125–130, 2006) recent work, in this paper we provide a class of estimators for π A , for a generic randomization scheme, when the mean of a supplementary non-sensitive variable is known. The minimum attainable variance bound of the class is obtained and the best estimator is also identified. We prove that the best estimator acts as a regression-type estimator which is at least as efficient as the corresponding estimator evaluated without allowing for the auxiliary variable. The general results are then applied to Warner and Simmons’ model.  相似文献

Current research on how adolescents cope with bullying is primarily quantitative, examines youth in Grades 1 through 6, and neglects to specifically assess how victims of bullying cope with being bullied. The current qualitative study explored the coping strategies of 22 rural middle- and high-school youth victimized by bullying. Results indicated that youth report using an array of emotion focused coping strategies (an internal coping strategy that focuses on emotion regulation) and problem focused coping strategies (active behaviors that are aimed to decrease or eradicate the stressor). These coping strategies included help seeking, physical and verbal aggression, standing up for themselves, and prosocial bystander behavior. While the majority of coping strategies were similar between middle- and high-school participants, these groups reported utilizing verbal and physical aggression in different ways. Further, certain coping strategies, such as help seeking and lashing out with physical and verbal aggression, were utilized as both emotion- and problem-focused coping strategies. Implications are discussed.  相似文献

Condoms protect against human immunodeficiency virus (HIV)/sexually transmitted infections (STIs) and unintended pregnancy and are essential to sexual health efforts targeting young adults, who are disproportionately affected by both outcomes. Understanding condom use motives is critical to increasing condom use. Research in this area is limited, particularly regarding the roles of partners and relationship factors. Using a longitudinal sample of 441 young adults and 684 reported partnerships we examined associations between relationship factors and condom use motives (pregnancy prevention, disease prevention, or dual protection). Simultaneous multilevel models identified variables associated with motives; level-specific models identified the levels (individual, partnership, time) variables impacted motives. Participants reported choosing condoms for pregnancy prevention, disease prevention, and dual protection in 51%, 17%, and 33% of partnerships, respectively. Partner-specific factors varied, to a differing degree, across the three levels. Seven variables (duration, condom self-efficacy, commitment, sexual decision-making, power, and vulnerability to harm [HIV/STIs] and pregnancy) distinguished condom use motives. The level of this association varied but was most pronounced at the partner and individual levels. Researchers and practitioners should consider the impact of both individual- and partner-level factors on condom use motives, in both research and sexual health programs.  相似文献

This article extends Bourdieu’s field theory to explain how learning spaces in the Toronto folk and metal scenes create gendered access to a field-specific form of cultural capital: performance capital, or the instrumental and interpersonal skills required to perform music. Folk musicians develop performance capital in open-access spaces, such as workshops and open stages at local folk clubs, while metal musicians learn in private spaces such as garages, basements, and rented rehearsal rooms. Folk’s learning spaces are open to all aspiring musicians, while access to heavy metal’s learning spaces relies on social networks from which women are often excluded. These different processes of capital development can lead to greater or lesser opportunities for women to become cultural producers: In Toronto, women make up approximately five percent of heavy metal musicians, but almost half of practicing folk musicians.  相似文献

Lipsky's analysis of the implementation gap in welfare policy in ‘Street-level Bureaucracy’ focuses on the problem of front-line discretion but ‘brackets off’ the discretion of senior managers. In this paper I draw on a qualitative study to argue that senior managers can also exercise significant discretion and that their discretion can contribute to the conditions of policy confusion and contradiction, and resource inadequacy that characterise ‘the corrupted world of service’ of front-line discretion. In this context front-line discretion may be used by front-line staff to bridge the policy implementation gap created by senior managers.  相似文献

Women artists are systematically disadvantaged across cultural fields. Although some of these disadvantages resemble gender inequalities in non‐artistic work, such as lower pay, underrepresentation, work–family conflict, and symbolic devaluation, others are unique to artistic careers. In this essay, I extend Acker's work on the implicit gendering of the ideal‐typical worker to show how gender implicitly organizes social expectations around artists and artistic work. I highlight themes emerging from past research on gender relations in artistic careers, which suggest that the ideal‐typical artist builds on a masculine model in at least three ways. First, collective understandings of creative genius center a masculine subject. Second, bias in aesthetic evaluations systematically favors men over women. Third, the structure of artistic careers, particularly the need for entrepreneurial labor and self‐promotion, requires artists to engage in behaviors that are more socially acceptable in men than in women.  相似文献

In this case study, we detail and analyze how the Tobacco Control Evaluation Center (TCEC), an evaluation technical assistance center that serves approximately 100 local tobacco control organizations in California, endeavors to build capacity among the state-funded local providers it serves by using evaluation capacity building activities with an utilization-focused evaluation framework. We call this a "blended approach" and describe these methods. Satisfaction and demand for TCEC services are documented to provide measurements for evaluation capacity building. Final evaluation report scores from two intervention cycles (2004-2007 and 2007-2010) submitted to the California Health Department, Tobacco Control Division are also assessed and compared. These measures demonstrate an increase in evaluation capacity by local projects under TCEC's purview.  相似文献
