Do the Falling Earnings of Immigrants Apply to Self‐employed Immigrants?

It is well known that the earnings of recent cohorts of immigrant men have fallen further behind native‐born men. Using several years of Canadian Census data, this study finds that immigrants have turned to self‐employment at a much faster rate than the native born. In addition, the earnings gap between self‐employed immigrant and native‐born men has not grown with successive cohorts, but rather has followed a cyclical movement: narrowing at the peak, and widening in times of weaker economic activity. However, immigrants choosing self‐employment still face challenges, as their earnings are far below native‐born earnings, and convergence is a lengthy process.     

Soziale Konfliktlinien und Wahlverhalten: Eine Analyse der Determinanten der Wahlabsicht bei Bundestagswahlen von 1969 bis 2009

The aim of this study is to analyse whether the impact of cleavages on voting behaviour in Germany has decreased over time. Additionally, the study evaluates whether the belonging to a social group is still of relevance for voting behaviour after including further theoretically derived determinants. On the basis of a pooled dataset that covers all German national election studies between 1969 and 2009, the analysis reveal that the class cleavage and the religious cleavage are still of relevance for voting behaviour in Germany, even when controlling for the voter’s candidate preference and problem-solving capacity of a political party as perceived by the voters.     

Marx,formal subsumption and the law

Recent work rethinking the place of the law in Marxian analysis of capitalist society provides us with a foundation for a renewed look at the labor process. Drawing on this literature, which emphasizes the materiality of institutions through which labor is exploited, and returning to Marx’s discussion of formal subsumption in Capital, I argue that the law was central for subordinating labor. I then present three case studies from industries in Victorian England to demonstrate the diverse ways in which law was implicated in formal subsumption. The case studies focus on the ways in which capitalists used master and servant law, the key law governing the workplace, to subordinate labor. I conclude by considering how these cases provoke us to consider the materiality of the law in labor relations more broadly, and such questions might be pursued in developing capitalist economies such as China.     

Natural Mentoring Relationships Among Adolescent Mothers: A Study of Resilience

This study focused on natural mentoring relationships between nonparental adults and African American adolescent mothers. Data were collected from 93 adolescent mothers over 5 time points, starting in the adolescent mothers' senior year of high school and ending 5 years after high school. We found that having a natural mentor was related to fewer depressive symptoms and fewer anxiety symptoms over time. Natural mentor presence also modified the relationship between stress and mental health problems over time. Facilitating these natural mentoring relationships between adolescent mothers and nonparental adults may be a useful strategy for promoting healthy development within this population.     

Constructing the Self in Early, Middle, and Late Adolescent Boys: Narrative Identity, Individuation, and Well-Being

The present study examined aspects of identity development in a sample of adolescent boys from two approaches: individuation and narrative. To extend the more recent research on narrative identity development, we also examined relations between narrative identity, well-being, and age. Narrative meaning making was predicted by themes of individuation in the narratives, specifically the interaction of autonomy and connectedness. Well-being was predicted by different aspects of meaning depending on the kind of meaning and the stage of adolescence. Finally, results showed an age-related increase in meaning-making processes, particularly meaning related to perceiving the self as changing. Results are discussed in terms of the processes of narrative identity development for adolescent boys.     

Entrepreneurship and Intergenerational Links in Switzerland

Abstract. The growing share of self‐employment among the workforce is one of the most striking phenomenon that has taken place on the Swiss labour market in the past 20 years. Although many factors can be put forward to explain this trend, no study in Switzerland has focused on the role of intergenerational links. This topic is quite important as one has to assess whether the surge in entrepreneurship has made this type of work accessible to anyone, or whether some constraints such as intergenerational links limit the supply of entrepreneurs. Based on data from the Swiss Household Panel, we find that a father self‐employed is the most important factor shaping the supply of self‐employed in Switzerland. Our results also suggest that self‐employment is not correlated to pecuniary factors.     

Random effects models for estimation of the probability and time to progression of a continuous biomarker

Biomarkers play a key role in the monitoring of disease progression. The time taken for an individual to reach a biomarker exceeding or lower than a meaningful threshold is often of interest. Due to the inherent variability of biomarkers, persistence criteria are sometimes included in the definitions of progression, such that only two consecutive measurements above or below the relevant threshold signal that “true” progression has occurred. In previous work, a novel approach was developed, which allowed estimation of the time to threshold using the parameters from a linear mixed model where the residual variance was assumed to be pure measurement error. In this paper, we extend this methodology so that serial correlation can be accommodated. Assuming that the Markov property holds and applying the chain rule of probabilities, we found that the probability of progression at each timepoint can be expressed simply as the product of conditional probabilities. The methodology is applied to a cohort of HIV positive individuals, where the time to reach a CD4 count threshold is estimated. The second application we present is based on a study on abdominal aortic aneurysms, where the time taken for an individual to reach a diameter exceeding 55 mm is studied. We observed that erroneously ignoring the residual correlation when it is strong may result in substantial overestimation of the time to threshold. The estimated probability of the biomarker reaching a threshold of interest, expected time to threshold, and confidence intervals are presented for selected patients in both applications.
