Explaining Attitudes towards Self-employment among Immigrants: A Canadian Case Study

Implicit in Canada's immigration policies is that some immigrants are endowed with a particular entrepreneurial spirit, and that this spirit relates to immigrants’ origin. This paper examines whether attitudes towards entrepreneurship indeed relate to origin, or whether they can be explained through labour market circumstances at the place of settlement and/or Canada's immigrant selection procedure. The empirical study focuses on the reported attitudes towards entrepreneurship. A survey of 509 Vancouver residents of a predominantly Chinese immigrant neighbourhood, a predominantly South Asian immigrant neighbourhood, and a neighbourhood of non‐immigrants reveals that ethnic origin is a weak indicator of entrepreneurial attitudes. Instead, urban or rural background emerges as a more powerful predictor. The results also raise doubts about whether the Canadian government's immigration policy, which selects immigrants on the basis of economic potential, indeed selects immigrants with a greater desire to become self‐employed. Furthermore, the amount of time immigrants have spent in Canada does not significantly affect attitudes towards entrepreneurship.     

Nutzenpotenziale und Effekte betrieblicher Gesundheitsförderung

Research regarding workplace health promotion (WHP) frequently neglects the employees’ perspective. Due to that, assumptions regarding the effects of WHP for employees are typically based on experts’ opinions but not statements from the workforce. The present paper therefore exploratively investigates the effects of WHP as perceived by the staff. The results of problem-centred interviews with 19 employees in three organizations, and the four people there responsible for WHP show that potential effects of WHP from the employees’ perspective can be grouped in five areas: (1) prevention is facilitated, (2) cognitive and affective changes are possible, (3) physical effects are observed, (4) emotional effects can arise, and (5) WHP can lead to social effects. As WHP’s potential positive effects can be hindered in case the employees’ perspective is not sufficiently taken into account, the individuals’ expectations and aims should become more central in WHP design and research.     

The Recurrence of Violence

This article examines the recurrence of violence in the contemporary world based on the premise that states can use their monopoly of violence not only for preserving the life of their citizens but also for the sake of terror and annihilation. This ambiguous nature of the use of violence derives from the fact that the legal order of the state is a function of concrete acts of bloodshed and killing. The state bases the law on violence because authorities fear the psychological attraction that bloodshed has on the human imagination. The contagious character of violence, however, is not based on man's innate potential for aggression. Rather, it depends on the nature of the reciprocity of social relations. Violent conflict often feeds on negative social communication such as hatred and desire for vengeance. Yet, faced with the inevitable recurrence of violence humans have the capacity to act on the spiral of vengeance. One possible way to pacify violence is to transform the destructive, negative reciprocity of retaliation into the creative, positive reciprocity of active non-violence.     

Robust-efficient fitting of mixed linear models: Methodology and theory

In many areas of application mixed linear models serve as a popular tool for analyzing highly complex data sets. For inference about fixed effects and variance components, likelihood-based methods such as (restricted) maximum likelihood estimators, (RE)ML, are commonly pursued. However, it is well-known that these fully efficient estimators are extremely sensitive to small deviations from hypothesized normality of random components as well as to other violations of distributional assumptions. In this article, we propose a new class of robust-efficient estimators for inference in mixed linear models. The new three-step estimation procedure provides truncated generalized least squares and variance components' estimators with hard-rejection weights adaptively computed from the data. More specifically, our data re-weighting mechanism first detects and removes within-subject outliers, then identifies and discards between-subject outliers, and finally it employs maximum likelihood procedures on the “clean” data. Theoretical efficiency and robustness properties of this approach are established.
