How leader role identity influences the process of leader emergence: A social network analysis

Contemporary theories on leadership development emphasize the importance of having a leader identity in building leadership skills and functioning effectively as leaders. We build on this approach by unpacking the role leader identity plays in the leader emergence process. Taking the perspective that leadership is a dynamic social process between group members, we propose a social network-based process model whereby leader role identity predicts network centrality (i.e., betweenness and indegree), which then contributes to leader emergence. We test our model using a sample of 88 cadets participating in a leadership development training course. In support of our model, cadets who possess a stronger leader role identity at the beginning of the course were more likely to emerge as leaders. However this relationship was only mediated by one form of network centrality, indegree centrality, reflecting one's ability to build relationships within one's group. Implications for research and practice are discussed.     

Probabilistic population projections for countries with generalized HIV/AIDS epidemics

In 2015, the United Nations (UN) issued probabilistic population projections for all countries up to 2100, by simulating future levels of total fertility and life expectancy and combining the results using a standard cohort component projection method. For the 40 countries with generalized HIV/AIDS epidemics, the mortality projections used the Spectrum/Estimation and Projection Package (EPP) model, a complex, multistate model designed for short-term projections of policy-relevant quantities for the epidemic. We propose a simpler approach that is more compatible with existing UN projection methods for other countries. Changes in life expectancy are projected probabilistically using a simple time series regression and then converted to age- and sex-specific mortality rates using model life tables designed for countries with HIV/AIDS epidemics. These are then input to the cohort component method, as for other countries. The method performed well in an out-of-sample cross-validation experiment. It gives similar short-run projections to Spectrum/EPP, while being simpler and avoiding multistate modelling.     

Youth emancipation and perceived job insecurity of parents and children

We test whether job insecurity of parents and children affect children’s moving-out decisions. Macroeconomic estimates for 13 European countries over 1983–2004 show that coresidence increases by 1.7 percentage points (PP) following a 10 PP rise in the share of youths perceiving their job to be insecure and declines by 1.1 PP following the same increment in insecurity for older workers. Microeconometric evidence for Italy in the mid-1990s shows that the probability of moving out increases by about half a percentage point for a one-standard-deviation increase in paternal insecurity and by one-third of a percentage point for a one-standard-deviation decrease in children’s insecurity.     

Exchanging Views: Knowledge Transfer Through Literary Translation

Translation supports cultural interaction by fostering mutual understanding and enabling people to access foreign cultures. Logically, translation also furthers knowledge transfer in a broad sense. Drawing on recent scholarship that focuses on the migration and mobility of literary products (Damrosch, 2003; Casanova, 2004), this article seeks to show that the knowledge generated by both the practice of translation and the interdisciplinary area of Translation Studies is a key factor in shaping the image of a national culture.     

Characteristics and Outcomes of College-Age Adults Enrolled in Private Residential Treatment: Implications for Practice

Substance use among college-age adults is of interest due to high levels of use and low levels of treatment access and engagement relative to other adults. Data collected from 1,972 clients in residential services were analyzed to investigate differences in use patterns, treatment outcomes, and other life area problems. Participants completed an Addiction Severity Index (ASI) and the University of Rhode Island Change Assessment (URICA) at baseline, and an ASI and Treatment Services Review at 1-month and 6-month postdischarge interviews. Almost a quarter (24.1%) of participants were college age (18–25 years old). They were more likely to be White and male, and less likely to complete treatment although they had a longer average length of stay. College-age adults improved on all outcome measures, and posttreatment service use shows significant difference between college-age and older participants. Implications for practice are discussed.     

Race and exits from white collar jobs: Differences in downward mobility processes among African American, Latino, and White males

Does race affect the route to downward mobility from white collar occupations? Data from Panel Study of Income Dynamics are used to assess the minority vulnerability thesis, which maintains there are race-specific processes of down ward occupational mobility among males from white collar occupations. Findings indicate that, consistent with theory, a racialized continuum exists across six years of the work-career. For Whites, the path to downward mobility is relatively narrow and structured by traditional stratification-based causal factors, namely, human capital, back ground socioeconomic status, and job/labor market characteristics. For African Americans, the route to downward mobility is broad-based and not captured by traditional stratification factors and Latinos occupy an intermediate ground between Whites and African Americans. Further, as predicted by theory, the racial gap in mobility processes between Whites and racial minorities is pronounced at the lower-tier of white collar employment. Finally, implications of the findings for understanding labor market inequalities on the basis of race are discussed.     

Does Viewing Pornography Diminish Religiosity Over Time? Evidence From Two-Wave Panel Data

Research consistently shows a negative association between religiosity and viewing pornography. While scholars typically assume that greater religiosity leads to less frequent pornography use, none have empirically examined whether the reverse could be true: that greater pornography use may lead to lower levels of religiosity over time. I tested for this possibility using two waves of the nationally representative Portraits of American Life Study (PALS). Persons who viewed pornography at all at Wave 1 reported more religious doubt, lower religious salience, and lower prayer frequency at Wave 2 compared to those who never viewed porn. Considering the effect of porn-viewing frequency, viewing porn more often at Wave 1 corresponded to increases in religious doubt and declining religious salience at Wave 2. However, the effect of earlier pornography use on later religious service attendance and prayer was curvilinear: Religious service attendance and prayer decline to a point and then increase at higher levels of pornography viewing. Testing for interactions revealed that all effects appear to hold regardless of gender. Findings suggest that viewing pornography may lead to declines in some dimensions of religiosity but at more extreme levels may actually stimulate, or at least be conducive to, greater religiosity along other dimensions.
