隔离房地产泡沫风险————基于住房增值参与证券（HAPN）的设计模拟

住房作为一种特殊商品具有消费和投资的双重属性。一方面,住房给居住者提供最基本的生活要素,满足消费效用;另一方面,住房又可以作为投资品,基于投资者风险偏好,带来短期的出租收入和长期的资产增值收益。这种消费和投资的二重性,在长期内为衍生关系,在短期内却有着内在矛盾。现有住房所有权制度将住房的二重性捆绑在一起,现存住房金融制度通过信贷杠杆更加重了这一矛盾。而这种特性和制度安排对房地产经济的波动起伏具有放大器的作用。为了隔离住房房地产泡沫,可以借助住房金融创新的设计思路,通过住房增值参与证券(HAPN)这种住房金融创新工具进行模拟分析和论证。结果表明,运用住房增值参与证券可以建立住房消费与炒房投机之间的防火墙,隔断房地产泡沫风险,促进住房市场健康发展。     

Getting Comfortable as “Fish Out of Water”: Using Qualitative Research Methods Training to Enhance the Technical Capacity of Family Therapy Trainees

This article describes a qualitative research methods training project undertaken in a COAMFTE‐accredited family therapy master’s‐level program. Graduate students were trained to collect research data for a qualitative study on the resilience of families displaced to the United States because of war and politically motivated violence in their country of origin. By involving trainees in a research project with refugees, the project was intended to address a gap in clinicians’ training, specific to the refugee population (Miller, Muzurovic, Worthington, Tipping, and Goldman, American Journal of Orthopsychiatry 2002; 72 : 341). However, the training process was also a way to increase the students’ skills at interviewing in complex situations, develop their cultural sensitivity beyond awareness, enhance their capacity for routine self‐reflection, and introduce them to basic practices of qualitative research methodology. In this article, we focus on the students’ experience of the training and discuss the potential implications of their feedback for family therapy training.     

Dispersing the Serials Collection and Measuring Paper: Cooperative Storage Efforts and Legacy Journals Management in a University Library

This article discusses workflows involved with contributing print journal back runs to scanning and storage efforts. The purpose of these efforts was to alleviate space problems in a library by consolidating stacks that were formerly used to house runs of bound journals. This article contributes to the literature on serials withdrawal projects by demonstrating database designs for tracking contributions made to cooperative storage facilities as well as highlighting an innovative solution for tracking the required linear feet for housing bound print collections.     

Maximum likelihood estimation for the wrapped Cauchy distribution

The wrapped Cauchy distribution is an alternative to the Fisher-von Mises distribution for modeling symmetric data on the circle, and its maximum likelihood estimate (m.l.e.) represents a robust alternative to the mean direction for estimating the location for circular data. Surprisingly, there appear to be no previous results on the m.l.e. for the wrapped Cauchy distribution. It is shown that for sample sizes greater than two, the m.l.e. exists, is unique, and can be found by solving the likelihood equations. Also, a simple algorithm is presented which converges to the m.l.e.     

Ethnic validity: A model for families on uncharted seas

This paper provides an ethnic validity framework as a model for conceptualizing and understanding the lives of ethnic minority families and the individuals in them. It outlines the ecological context of minorities (nonculture- defining groups) in a culture defined and dominated by a culture- defining group majority. Cross- ethnic/racial and cross- cultural studies organized around themes of acculturation and psychosocial competence are cited to substantiate the utility of this model. Their findings also provide a basis for outlining individual, family, and societal intervention approaches which can facilitate each group's ethnic validity and lead to a culturally diverse society which is more equitable for all of its members.     

Time,bounded utility,and the St. Petersburg paradox

The assumption of bounded utility function resolves the St. Petersburg paradox. The justification for such a bound is provided by Brito, who argues that limited time will bound the utility function. However, a reformulated St. Petersburg game, which is played for both money and time, effectively circumvents Brito's justification for a bound. Hence, no convincing justification for bounding the utility function yet exists.     

Media and agenda setting: effects on the public, interest group leaders, policy makers, and policy

Using an experimental design built around a single media event, the authors explored the impact of the media upon the general public, policy makers, interest group leaders, and public policy. The results suggested that the media influenced views about issue importance among the general public and government policy makers. The study suggests, however, that it was not this change in public opinion which led to subsequent policy changes. Instead, policy change resulted from collaboration between journalists and government staff members.     

Making a match: inexperienced physician executives and the job market

Hospitals and other health care organizations are adding physician executives at such a rate that demand is outstripping supply-there are more opportunities for seasoned physician executives than there are physicians with track records as medical managers. It is possible that hiring management will have to consider the employment of a physician who wants to be in management but has no track record as a physician executive. In some cases, it may even be preferable to employ a neophyte physician executive, especially when the physician is a respected clinician already on the organization's medical staff. In selecting such a physician, however, an evaluation must be made of the probability that the physician will be successful in the new role. The author points to 10 criteria that the hiring organization should observe in hiring inexperienced managers.     

“STREETVILLE FOREVER”: ETHNICITY,COLLECTIVE ACTION,AND THE STATE

Contemporary state policies in European and American societies mark a shift from older forms of governance focussed on the centrally concentrated state toward strategies that aim to limit governmental intervention by getting people to govern themselves. This means that individuals and communities are charged with carrying out roles and functions that were traditionally performed by the state. In this article I examine the conditions in which local people in an urban neighbourhood in the United Kingdom who were the objects of this new mode of governance came to negotiate and resist its policies and structures. Residents and community workers came together in opposition to the local Council to make demands that they considered to be of interest to the members of their neighbourhood across ethnic, racial, gender, and class boundaries. In so doing they crafted a multiracial neighbourhood identity that was more inclusive than the categories deployed by the state. This examination of collective initiatives that resist and challenge the state's strategies for local governance illuminates some of the complexities, contradictions, and limits of the contemporary state.     

Sexual Attitudes and Behavior of University Students at a Rural South African University: Results of a Pilot Survey

A cross sectional qualitative and quantitative pilot survey, using self-administered questionnaire and focus group discussions, was conducted to assess the feasibility of a health promotion programme implemented at the university. About 73 students participated in the survey and the discussion. We examined gender and cultural differences on sexual attitude and behaviour. There was a strong belief that unprotected sex can lead to pregnancy and STIs. Overall participants were not sure if condom use had any negative effects, although female respondents felt that condoms affect the pleasure of sexual intercourse.

The results suggest that there is a need for health promotion programmes aimed at young adults, who attend university. The programme should improve general health knowledge, targeting health promotion and sexual risk behaviour among university students. Such a programme would have to consider gender, socio-economic circumstances as well as national and cultural background of the target population.
