Responsibility-Alleviation and Other-Regarding Preferences with Peer Workers in Labor Markets: An Experimental Investigation

A peer worker is introduced in a controlled labor market experiment characterized by unobservable effort and incomplete contracts. Workers make decisions independently and without knowledge of each other??s actions in a modified gift exchange experiment. Introducing a peer worker into an ongoing market has a negative and significant effect on effort. This decrease in effort is consistent with responsibility-alleviation on the part of employees and not with other-regarding equity concerns for the manager??s payoffs.     

Peer Estimates of School-Aged Boys' and Girls'Aggression to Same- and Cross-Sex Targets

Research comparing boys' and girls' aggression has typically focused on the overall amount of aggression using a within-sex design. Less attention has been given to differences in children's aggression according to the sex of the target. In the research reported here, boys' and girls' amount and style of aggression were compared for same- and cross-sex targets. A peer estimation procedure was used with children in Grades 2, 6, 9, and 11. Physical, verbal, and indirect aggression were studied. Although there were some differences according to Grade level, both the amount and style of aggression for boys and for girls differed as a function of the sex of target, with cross-sex aggression generally falling between the amount and style of boys -to-boys and girls-to-girls aggression. The results draw attention to the possible separate nature of the cross-sex context, and highlight the importance of taking into account the target of aggression when investigating differences in aggression between boys and girls.     

Mapping the City: Innovation and Continuity in the Chicago School of Sociology, 1920–1934

This paper examines the historical origins and theoretical underpinnings of the maps of the city of Chicago produced by sociologists at the University of Chicago between 1920 and 1934. I argue that the three mapping schemes produced in those years—the concentric zone map of The City (1925), the base map of 75 community areas and the census tract maps published in three volumes of Census Data of the City of Chicago (1920, 1930, 1934)—draw upon distinct historical antecedents and have distinct theoretical implications. The first scheme exhibits the strong influence of Johann Heinrich von Thünen’s location theory and maps produced by early Chicago city boosters, the second most clearly exhibits the influence of the Social Survey Movement and of pragmatist philosophy and the third, the influence of the financial and governmental interests of the organizations that made up the Chicago Census Committee. Literature on early urban sociology and mapping in Chicago has hitherto not adequately differentiated these three mapping schemes or problematized the implications of their differences for our understanding of the theoretical commitments of the “Chicago School.”     

How leader humility helps teams to be humbler,psychologically stronger,and more effective: A moderated mediation model

We hypothesize that (a) the level of humility expressed by leaders predicts team performance through, serially, team humility and team PsyCap, and (b) the strength (i.e., consensus within the team) of the leader humility, team humility and team PsyCap moderates the paths of that hypothesized model. A sample comprising 82 teams (82 leaders; 332 team members) was collected. Team members reported leader humility, team humility and team PsyCap. Leaders reported team performance. To handle the risks of common method bias, each mediating path of the hypothesized model is based on data from two different subsamples within each team. Our model's most novel theoretical contribution is the (moderated mediated) connection between leader humility, collective humility, and team PsyCap, and this was consistently supported in our data. Our inconsistent findings dealing with the relationship between team PsyCap and performance is well established in the literature and our results in both sub-samples were in the theorized direction. The study contributes to understand why, how and when humble leaders are more effective.     

THE EFFECT OF POST-HIGH SCHOOL SOCIAL CONTEXT ON SELF-ESTEEM

This study examines the effect of post-high school social context on self-concept development by assessing changes in positive self-esteem (i.e., self-confidence) in a national longitudinal sample of males who entered the full-time labor force, the active federal military, or college after high school. The data are from Bachman's Youth in Transition study of 2,213 American high school students in five data waves between 1966 and 1974. Estimation of a LISREL structural equation model shows that of the three contexts, the military has the most significant (negative) net impact on self-concept, followed by work (slightly negative), and college (no impact). It is argued that the observed negative effect of the military context (and possibly the work context) is rooted in the larger sociohistorical processes impinging on the individual, and on the workers' and servicemen's low organizational positions. College's lack of effect appears to be due to the students' relatively high prior self-esteem and the possibility that college impacts social and political values more than self-worth. The number of months in a context positively relates to later self-esteem. It is argued that duration may work through acclimation to the role demands of one's context and to an increase in feelings of mastery and control.     

Is It Facebook Official? Coming Out and Passing Strategies of Young Adult Gay Men on Social Media

The rapid proliferation of social media, mobile applications, and Internet technologies has shifted a wide variety of social interaction from physical spaces to an online environment. Drawing from 42 semistructured, in-depth interviews with gay college-aged men between the ages of 18 and 27, this article explores these changing patterns of social interaction among gay men. I discuss three strategies of identity management college-aged gay men use to disclose or conceal their sexual identity to others. The first group of men, “Out and Proud,” uses Facebook as a way to celebrate and reaffirm their sexual identity, in addition to actively coming out to others on the social media Web site. The second group, “Out and Discreet,” uses Facebook to indirectly come out to some of their friends while hiding this information from others. The men in the last group I identify, “Facebook Closeted,” actively manage their online profiles to ensure their sexual identity is not exposed. Facebook is both transformative and risky for college-aged gay men, as it represents a new platform for them to come out as gay to friends and family, as well as other areas of their lives where they must actively manage the presentation of their sexual identity.     

Do other-regarding preferences change with age? Evidence from a gift exchange experiment

A series of laboratory experiments investigate potential differences in other-regarding behavior by age of participant. Specifically, a gift exchange experiment is conducted with eighth graders, high school seniors, undergraduates, and working adults, all with similar observable demographic characteristics. All groups exhibit significant levels of gift exchange. Eighth graders exhibit significantly less gift exchange than other groups whereas the responses of other groups do not appear to differ. The findings indicate that other-regarding behavior is present, but still developing in adolescents and undergraduate subjects in gift exchange experiments exhibit similar behavior to adults with similar observable characteristics.     

A model for analyzing insect stage-frequency data when mortality varies with time

Summary A model is developed for the analysis of insect stage-frequency data which may be applied to populations with age-dependent mortality. The analysis of stage-frequency data is divided into two steps. In the first step, the number of different mortality rates and their values are estimated. The second step provides estimates of developmental rates and variances for each developmental stage and in addition provides estimates of the number of recruits to each stage. The model may be used both in analysis and prediction of insect stage frequencies. Hence, in addition to estimating developmental and mortality rates from stage-frequency data, it may also be used as a simulation model for an insect population. The model is applied to two populations ofHemileuca oliviae Cockerell, a lepidopterous pest of New Mexico grasslands. The model identifies, in the two populations, different mortality rates that are related to plant productivity.
