AT THE MOVIES: THE ECONOMICS OF EXHIBITION CONTRACTS

We describe a real-world profit sharing contract—the movie exhibition contract—and consider alternative explanations for its use. Two explanations based on difficulties with forecasting fit the facts better than asymmetric information models. The first emphasizes two-sided risk aversion; the second emphasizes measurement costs. Transaction costs and long-term relationships also affect contractual practices. We use an original data set of all exhibition contracts involving 13 theaters owned by a prominent St. Louis exhibitor over a two-year period to inform our theories and test hypotheses. The findings question traditional contract theory and may be relevant for other contracting environments.(JEL L14 , L82 , D45 , D80 )     

利用双电极装置提高等电聚焦通量

在最大电压12 000 V下操作,蛋白质在固定pH梯度(IPGs)上的等电聚集(IEF)可以在3 h内完成。采用改装的电极装置,将两电极对通过线路并联,可使IEF的通量加倍。、与常规的单电极对相比,成对的IPGs的电压梯度几乎一致,并在大致两倍的电流下运行,IEF可在大致相同的时间内完成。     

Race,Religion, and Opposition to Same‐Sex Marriage*

Objective. We examine racial differences in support for same‐sex marriage, and test whether the emerging black‐white gap is a function of religiosity. We explore how religious factors play a crucial role in racial differences, and how secular factors have varying effects on attitudes for whites and African Americans. Methods. Using data from the General Social Surveys, we estimate ordinal logistic regression models and stacked structural equation models. Results. We show that the racial divide is a function of African Americans' ties to sectarian Protestant religious denominations and high rates of church attendance. We also show racial differences in the influence of education and political values on opposition to same sex marriage. Conclusions. Religious factors are a source of racial differences in support for same‐sex marriage, and secular influences play less of a role in structuring African Americans' beliefs about same‐sex marriage.     

A new family of multivariate heavy-tailed distributions with variable marginal amounts of tailweight: application to robust clustering

We propose a family of multivariate heavy-tailed distributions that allow variable marginal amounts of tailweight. The originality comes from introducing multidimensional instead of univariate scale variables for the mixture of scaled Gaussian family of distributions. In contrast to most existing approaches, the derived distributions can account for a variety of shapes and have a simple tractable form with a closed-form probability density function whatever the dimension. We examine a number of properties of these distributions and illustrate them in the particular case of Pearson type VII and t tails. For these latter cases, we provide maximum likelihood estimation of the parameters and illustrate their modelling flexibility on simulated and real data clustering examples.     

Attribution of rape blame as a function of victim gender and sexuality,and perceived similarity to the victim

This study examined respondents' perceived level of blame and responsibility for three victims of rape, as a function of attitudes toward homosexuals, and perceived similarity to the victim, as indicative of Shaver's (1970) Defensive Attribution Hypothesis. Victims were a homosexual and heterosexual male, and a female. A sample of 168 university students completed questionnaires, which included three rape scenarios and subsequent questions, the Index of Attitudes Toward Homosexuals (Hudson & Ricketts, 1980), and the short-form Marlowe-Crowne Social Desirability Scale (Reynolds, 1982). Results indicated that respondents higher in homophobia (regardless of gender) blamed the homosexual male rape victim and the behavior and character of the heterosexual male rape victim, more than the female rape victim. Male respondents in general also blamed the heterosexual male rape victim, more than female respondents. Shaver's defensive attribution hypothesis was not supported. Results are discussed in terms of the possible link between homophobia and male blame.     

Effect of ceasing creatine supplementation while maintaining resistance training in older men

The authors previously found that creatine (Cr) combined with 12 weeks of resistance training enhanced muscle strength and endurance and lean tissue mass (LTM) in older men. Their purpose in this study was to assess these variables with cessation of Cr combined with 12 weeks of reduced training (33% lower volume) in a subgroup of these men (n = 8, 73 years old) compared with 5 men (69 years old) who did not receive Cr. Strength (1-repetition maximum [1-RM]), endurance (maximum number of repetitions over 3 sets at 70-80% 1-RM), and LTM (dual-energy X-ray absorptiometry) were assessed before and after 12 weeks of Cr cessation combined with reduced-volume training. No changes in strength or LTM occurred. Muscle endurance was significantly reduced (7-21%; p <.05), with the rate of change similar between groups. Withdrawal from Cr had no effect on the rate of strength, endurance, and loss of lean tissue mass with 12 weeks of reduced-volume training.     

‘Masters of the Universe’: Demystifying Leadership in the Context of the 2008 Global Financial Crisis

There have been numerous explanations of the 2008 global financial crisis, ranging from the greed of the bankers to excessive deregulation due to neoliberalism and the financialization of everything. This paper argues that a discussion of parallels between the crisis and leadership discourses can generate new insights into both. Through an empirical study of the subjectivity of leaders in a UK building society, discourses around both leadership and the crisis are argued to reflect and reproduce similar taken‐for‐granted assumptions about subjectivity and representations of organizational and economic life. These are grounded in the belief that leaders are ‘Masters of the Universe’, who are able to predict and secure the future. The authors believe that these assumptions and representations contributed to the crisis and are now in danger of producing yet another bubble.     

Racial and Ethnic Differences in Experiences of Discrimination in Accessing Social Services Among Transgender/Gender-Nonconforming People

Members of the transgender/gender-nonconforming (GNC) community experience higher rates of discrimination based on their gender compared to their cisgender counterparts. Similarly, people of color experience higher rates of discrimination than White people. This study examines the difference in experiences of discrimination among transgender/GNC individuals in accessing social services providers by race/ethnicity (White and people of color). The data collected in a national cross-sectional survey (N = 6,451) and analyzed via chi-square test of independence and binary logistic regression demonstrate the disproportionate prevalence of discrimination based on race/ethnicity within the transgender/GNC population when accessing social services such as drug treatment centers, mental health clinics, domestic violence shelters, and rape crisis centers. Social workers are the most common provider of social services to the community, and have an ethical commitment to provision of services without discrimination. High rates of discrimination in accessing social services among transgender/GNC people, with even higher rates of discrimination for transgender/GNC people of color, highlight the need for improvement in social work education and practice.     

Twelve‐Month‐Old Infants’ Sensitivity to Others’ Emotions Following Positive and Negative Events

This study investigated infants’ sensitivity to others’ congruent and incongruent emotional reactions to positive and negative events. Thirty‐six 12‐month‐old infants viewed three distinct interpersonal events (give a toy, break a toy, fight over a toy) followed by an emotional expression (happiness, sadness, anger) that was either congruent or incongruent with the preceding event outcome. The duration of infants' looking toward each emotional reaction was examined. Infants demonstrated sensitivity to incongruent emotional reactions for the give and fight events, representing the earliest evidence to date of emotional sensitivity to negative events.
