This study employs a simple enrollment demand model to investigate the regional market environment of a private, church-related, comprehensive institution of higher education offering undergraduate, graduate and professional education. The focus is on price and cross-price elasticities of demand as measures of the competitive threat posed by prominent public and private educational alternatives within the region. We find a significant competitive threat coming from the private sector within the region. This competition raises the net price elasticity of demand for education at this institution to well above unity. We conclude that tuition price subsidies play a critical role in managing enrollment demand at this institution. [JEL J3, J24, J41] 相似文献

Media pluralism is valued in most jurisdictions because it contributes to a well-informed citizenry. The authors examine what media policy and regulatory levers appear to affect five types of citizen knowledge across the European Union. They conclude that concentration of titles matters more than ownership in newsprint; and that neither type of concentration matters in broadcasting in the same way, but the regulatory regime for public service broadcasting does, particularly for political knowledge. 相似文献

Mixed marriages are a hemorrhage in the body of American Jewry. In the average Hebrew school classroom 20–25 percent of the students will someday marry out. Even in day schools 5–10 percent will marry out, although most of them will influence their spouses to convert. (Jewish children who do not receive a Jewish education will marry out in even higher percentages, and rarely influence their partners to become Jewish.) This exogamy (outmarriage) results in a doubling of the divorce rate. In addition, the majority of the children of exogamous manages do not identify themselves as Jews. Can Jewish educators influence some of these children to consciously seek Jewish mates? only if they try. 相似文献

In this article, we investigate how the national imperative to increase opportunities for young women of color in science, technology, engineering, and mathematics (STEM) and to broaden their participation was taken up locally at two high schools in one school district. Using ethnographic and longitudinal data, we focus on four young women of color (two at each school) as they negotiated STEM-related identities in the discursive and practice contexts of their lives at school. Using Holland and Lave’s concept of history in person, we view the young women as fighting for particular versions of a future self while entangled in discursive and social relations that threatened to position them differently than they wished to be. We find that their fight for future selves was not—for them—with the national narrative about women of color in STEM but with local school narratives that negatively positioned students of color more broadly and remained silent on issues of gender, the intersection of gender and race, and the implications for STEM. High school success in STEM came as a hopeful but potentially fragile byproduct of struggles to differentiate themselves from people like them (other Blacks, Latinas, the poor). Implications of these findings are discussed. 相似文献

A growing body of research indicates connections exist between action, perception, and cognition in infants. In this study, associated changes between sitting ability and upright face processing were tested in 111 infants. Using the visual habituation “switch” task (C. H. Cashon & L. B. Cohen, 2004; L. B. Cohen & C. H. Cashon, 2001), holistic processing of faces was assessed in same‐aged non‐ and near sitters (22–25 weeks) and same‐aged new and expert sitters (27–32 weeks). U‐shaped relation was found between sitting stage and holistic face processing such that only nonsitters and expert sitters processed faces holistically. It is posited that the results are due to a reorganization of the upright face‐processing system resulting from infants' learning to sit independently and trying to incorporate the meaning of upright faces. 相似文献

In this paper, we report on an investigation into sustainability education in schools in the Australian state of Tasmania following the implementation of the Australian Curriculum. Sustainability is one of three cross-curriculum priorities in the new national curriculum and is the focus of this research (sustainability cross-curriculum priority (CCP)). Principals and Curriculum Leaders (PCLs) from all schools in Tasmania were invited to complete a survey that asked them about their understanding of various aspects of sustainability and how the sustainability CCP was integrated across learning areas. Sixty-eight PCLs (24%) responded to the survey. They reported generally good understandings of sustainability and education for sustainability, but lesser understandings of the sustainability CCP and the nine organising ideas. Respondents’ understandings of sustainability were dominated by an environmental focus. The PCLs’ responses in relation to sustainability implementation across learning areas gave insights into ways that the sustainability CCP can serve as a pivot for cross-curricular teaching and learning, which is strongly advocated for achieving transformative sustainability education. We conclude this paper with a discussion of how the sustainability CCP is an important asset in the necessary reorientation of the Australian formal education system for a more sustainable future. We note the importance of professional support so that educators may better understand sustainability and its complexity as a cross-curricular priority and envision ways in which the sustainability CCP can be realised within education. 相似文献

A positive, nonjudgmental, and informed approach to sexual health during pregnancy promotes acceptance of the normal functioning of women's bodies. It also encourages the development of close and supportive relationships that are so essential during pregnancy and birth. Common concerns do not need to become problems. Concerns include issues of libido, positioning, and preterm labor or fetal health, as well as myths and cultural attitudes. Childbirth educators can use tools such as the PLISSIT model to approach the topic of sexuality during pregnancy. In addition, opportunities are available in every childbirth class to acknowledge or ignore sexual issues. Perinatal educators who take responsibility for addressing this often-taboo topic can enhance women's feelings of safety and their confidence in normal birth. 相似文献

ABSTRACTThis paper assesses the reliability and validity of the teacher-completed Pupil Behaviour Questionnaire (PBQ), by comparing it to the already extensively validated teacher-completed Strengths and Difficulties Questionnaire (SDQ). Participants included 2074 primary school children participating in a universal school-based trial and 41 vulnerable children who were taking part in a study exploring the impact of exclusion from school. Exploratory factor analysis results (first factor accounts for 80.8% of the variation in the items) and the high Cronbach’s alpha value of 0.85 indicate that the PBQ consists of one substantive factor/dimension. Strong correlations between the total PBQ score and the conduct sub-scale (Spearman’s correlation coefficient (rs) = 0.67) and total difficulties score (rs = 0.59) of the SDQ indicate convergent validity. This study suggests that the PBQ is a reliable measure, and provides some evidence of validity. Further work is needed to test the PBQ in an older, more diverse populations and to measure sensitivity to change. 相似文献
