This study replicates and extends research on college students’ sexual possible selves by longitudinally examining their sexual expectations, fears, and behavioral strategies at the beginning and end of the first semester in college. Open-ended responses were collected at two time points (T1, N?=?78; T2, N?=?40) and were analyzed using directed content analysis. First semester students’ salient expectations and fears focused on abstinence, interpersonal relationships, quantity, conditional sex, decreasing/avoidant behaviors, and fears related to sexual health/well-being, sexual assault/coercion, self-focus, and increased sexual risk at both T1 and T2. However, two new themes emerged at T2: maintain (expected) and partner-focus (feared). At both time points, behavioral strategies included abstinence, making opportunities, restricting boundaries, sexual health/well-being, thoughtful/informed decisions, and self-assertion/protection. Quantitative frequency comparisons were also conducted to examine changes in the prevalence of the reported categories and indicated shifts in salient expectations, fears, and strategies across the first semester. Implications for sexual education are discussed. 相似文献

Air pollution is one of the environmental influences that degrade cultural heritage objects situated indoors. Other essential influences, such as temperature, relative humidity, and light are often well monitored. The presence of air pollutants is less often measured or included in risk assessment. The MEMORI® technology presented in this paper was developed as a tool for easy measurement and assessment of the general risk of degradation of heritage objects situated indoors due to indoor exposure to air pollutants. MEMORI dosimetry was performed in locations belonging to English Heritage and Tate (both located in London) and the National Archives of Norway in Oslo, to assess air quality. The related damage risk for collection objects and the protection offered by display and storage designs was assessed. A high level of acidic effect was observed inside a number of showcases, and a high level of oxidizing effect was observed in some room locations. Relatively simple mitigation measures, such as constructing tightly sealed showcases using low emitting materials, installing active carbon absorbing media inside a ‘microclimate’ frame, and using cardboard storage boxes for paper, significantly improved air quality. Overall, implementation of such measures is likely to improve the preservation of objects and reduce conservation costs. 相似文献

The issue raised by the authors in this article question why studio art continues to be ignored as a site and source for research in art education. The necessity of the field to be able to participate within the research community in addressing cultural, social, educational and political concerns is acknowledged. It is argued, however, that the exclusive use of methods of inquiry that align with the conventions of social science research has been done at the expense of fully appreciating the capacity of artistic research undertaken in studio contexts. This tendency is especially prevalent in doctoral research in higher education. Three accounts of dissertation research are given that incorporate studio activity as a central agency of inquiry in conceptualising and theorising issues. Each highlights the capacity of art practice to reveal insights that are a consequence of what the researcher did in the studio setting as issues, ideas and interpretive stances emerged, and problems were re‐conceptualised. What is different in these accounts from more mainstream approaches to research is the readiness to accept that constructing new knowledge is a creative and critical process. 相似文献

The high school grade point average (GPA) is often adjusted to account for nominal indicators of course rigor, such as “honors” or “advanced placement.” Adjusted GPAs—also known as weighted GPAs—are frequently used for computing students’ rank in class and in the college admission process. Despite the high stakes attached to GPA, weighting policies vary considerably across states and high schools. Previous methods of estimating weighting parameters have used regression models with college course performance as the dependent variable. We discuss and demonstrate the suitability of the graded response model for estimating GPA weighting parameters and evaluating traditional weighting schemes. In our sample, which was limited to self‐reported performance in high school mathematics courses, we found that commonly used policies award more than twice the bonus points necessary to create parity for standard and advanced courses. 相似文献

This paper is based on research into the Treatment Action Campaign (TAC) in South Africa. The research investigated whether, through being active members of this social movement, HIV‐positive activists learn things they could not otherwise learn about their status and the epidemic, and how they put such knowledge to use. We show how activists develop a critical understanding of the underlying causes of their ill health and its link to economic poverty and global politics. The paper concludes by suggesting that adult educators can assume direct responsibility for poverty reduction by working in and with social movements. 相似文献

A national survey has shown that the incidence of serious behavioural problems in Danish schools stands at 10 per cent. The present qualitative study makes use of a broad-spectrum ecological model in the search for aetiological factors underlying behavioural disturbance. The study covers 34 typical Danish schools matched in pairs on the basis of degree of disturbance in the national survey. The results indicate behavioural problems to be related more to system factors than to purely individual factors. 相似文献

Curriculum and the idea of a cosmopolitan inheritance 总被引:4,自引:3,他引:1

The ancient idea of cosmopolitanism is a topic of renewed interest today. Scholars and practitioners in many fields are examining what it means to conceive all human beings as linked by their membership in a shared cosmos. Some people focus on political cosmopolitanism, others on moral, cultural, or economic cosmopolitanism. This paper examines educational cosmopolitanism by elucidating the idea of curriculum as a cosmopolitan inheritance. It argues that curriculum can generate a cosmopolitan sensibility, by which one means an outlook that regards life experience as universally educational. It suggests that a cosmopolitan sensibility can assist people in working through some of the tensions that accompany global and local change in our time. It can position them to reconstruct creatively cultural and individual values rather than abandon them in the face of the ceaseless pressure of globalization. A cosmopolitan sensibility edifies human beings by helping them perceive why all persons, in principle, can be creative guardians and practitioners of creativity itself. 相似文献
