Changing Attitudes Toward the Homeless: The Effects of Prosocial Communication With the Homeless

One hundred, thirty-four undergraduate students participated in a field experiment designed to examine the effects of extended, prosocial communication with homeless persons, upon attitudes toward the homeless problem, of behavioral intentions towards the homeless, and of causal attributions about homelessness. It was expected that prosocial interaction with the homeless would produce shifts in attitudes and behavioral intentions toward the homeless and homelessness and result in greater attributions of external causes to explain homelessness. Nineteen experimental participants worked 15 hours at a local homeless shelter. Their responses to a posttest questionnaire that measured a range of attitudinal and behavioral orientations toward the homeless were compared with control participants who did not work at the shelter. Subsequent analyses furnished strong evidence of positive changes in attitudes and intentions toward homelessness among the shelter workers. These participants evaluated homeless people as less blameworthy and more socially attractive than did control participants; moreover, shelter workers indicated more personal responsibility and behavioral commitment to helping the homeless than control participants. They also perceived the homeless problem to be more serious and were more likely to attribute homelessness to bad luck than control participants. However, the two groups were equally likely to attribute homelessness to various external causes such as the economy, housing costs, and governmental policies. The results are interpreted as having policy implications for volunteer service.     

Pay for performance--a clash of cultures

Implementation of pay for performance is being widely heralded as a new paradigm. However, the concept is not only alien to physicians, but may be ethically abhorrent, as well.     

Race Differences in Family Experience and Early Sexual Initiation: Dynamic Models of Family Structure and Family Change

We examine the effects of family structure on age at first sexual intercourse before marriage for a recent cohort of women. Previous research on the linkage between family structure and sexual initiation has employed relatively crude measures of family structure—typically a snapshot of the respondent's family structure at age 14. We use retrospective parent histories from the 1979–1987 National Longitudinal Survey of Youth to construct dynamic measures of family structure, using information on the number and types of parents in the respondent's household between birth and age 18. We use these measures in proportional hazard models to test the effects of prolonged exposure to a single‐mother family, prolonged absence of a biological father, parental presence during adolescence, and family turbulence. For White women, age‐specific rates of first sexual intercourse are significantly and positively associated with the number of family transitions; for Black women, age‐specific rates are significantly and positively associated with having resided in a mother‐only or father‐only family during adolescence. Net of other effects of family structure, we find no significant effects for White or Black women of being born out of wedlock, prolonged exposure to a single‐mother family, or prolonged absence of a biological father. Our results for White women are consistent with a turbulence hypothesis, whereas for Black women our results suggest the importance of family structure during adolescence. For neither White nor Black women are our results consistent with hypotheses positing earlier initiation of sexual activity for women with prolonged exposure to a single‐mother or father‐absent family.

关键时刻的语境大串联——关于文化研究的对话

这里刊出的是两位著名文化研究学者的一篇对话,主题自然是文化研究。劳伦斯.格罗斯伯格早年学习历史与哲学,后在英国伯明翰大学当代文化研究中心做研究,师从文化研究领军人斯图尔特.霍尔。他撰写和主编的大量论著在文化研究领域具有广泛影响,许多成为经典性论著。他主编的《文化研究》杂志,创刊于1987年。20年来,该杂志发表了近千篇学术论文,对文化研究领域的形成和发展有举足轻重的意义。刘康现担任美国杜克大学公共政策学院中国传媒中心主任、教授,南京大学兼职教授。照对话者的看法,文化研究的要旨在于如何“讲好故事”,路径之一乃是“串联”(articulation,又译作“接合”)。“串联”概念源出于斯图尔特.霍尔,旨在将不同事物联系起来构成新东西。对话者首先提出了跨学科的“串联”,以问题为中心,将不同学科的视角、方法、观念和理论相互碰撞,必然会产生各种新的观念。以问题为核心,就是强调回到问题本身是研究之宗旨所在。这就触及到所谓的“激进的语境主义”,也就是将特定问题带回到它们出现的那个特定社会、政治、经济和文化背景之中。提倡从问题出发、反对理论先行,这就击中了当前一些文化研究普遍存在的弊端。“关键时刻”概念特指社会矛盾激化的重要时刻,是语境的另一种描述,中国和西方目前都处在这一时刻。劳动的贬值,共同价值的衰落,文化的经济化,消费社会的崛起,传媒的影响等,都作为关键时刻的问题凸现出来,向文化研究提出了挑战。理论如何与大众“串联”,是对话又一重要主题,将文化研究变成公共知识,而非学院派的密语,看来是今后文化研究所面临的难题。在这方面右派比左派做得更好,也更有效,倒是一个发人深省的问题。于是,文化研究议程的创新,特别是在中国,如何从理论消费转向理论生产,乃是一个不容忽视的重大问题。     

BUSINESS COMBINATION DECISIONS: A U.S./CANADA STUDY*

The purpose of this paper is to clarify the motives behind business combination decisions. Twenty-one favorable characteristics associated with the motivations for business combinations were selected to serve as the basis for an empirical survey. Our analysis revealed that there are seven motivational variables of varying import and that the motivations underlying business combination decisions are similar for U.S. and Canadian executives.     

SENSITIVITY ANALYSIS WITH INTERACTION EFFECTS

The purpose of this paper is to extend the sensitivity analysis methodology as it applies to linear programming. The methodology developed herein is concerned with those changes in a technological coefficient that cause simultaneous changes in the relevant cost coefficients of the objective function. By proceeding from the definitions of feasibility and optimality, the authors develop formulas for determining bounds on the extent to which a technological coefficient, which has a predetermined effect on the corresponding cost coefficient, can vary without changing the optimal set of activities. After the formulas are developed, their use is demonstrated on a product-mix problem. This technique is of interest because changes in the rate at which an input is utilized can be expected to change the cost per unit of a resulting product. This interdependence should be recognized whenever a sensitivity analysis is performed on a technological coefficient of either a cost minimization or a contribution margin maximization problem.
