Are there gender and country of origin differences in immigrant labor market outcomes across European destinations?

The 1994–2000 waves of the European Community Household Panel are used to study the earnings of immigrants as compared to native workers in 15 European countries. At the time of arrival, there is a significant negative partial effect of foreign birth on individual earnings compared to the native born in the destination of around 40%. These differences vary across origins and destinations and by gender. Immigrant earnings catch-up to those of the native born after around 18 years in the destination. Schooling matters more for earnings for women, whereas, language skills are relatively more important for men.

Colourism and African–american wealth: evidence from the nineteenth-century south

Black is not always black. Subtle distinctions in skin tone translate into significant differences in outcomes. Data on more than 15,000 households interviewed during the 1860 US federal census exhibit sharp differences in wealth holdings between white, mulatto, and black households in the urban South. We document these differences, investigate relationships between wealth and recorded household characteristics, and decompose the wealth gaps to examine the returns to racial characteristics. The analysis reveals a distinct racial hierarchy. Black wealth was only 20% of white wealth, but mulattoes held nearly 50% of whites’ wealth. This advantage is consistent with colourism, the favouritism shown to those of lighter complexion.

ATTITUDES TOWARDS THE EURO: AN EMPIRICAL STUDY BASED ON THE GERMAN SOCIO-ECONOMIC PANEL (SOEP)

This paper investigates changing attitudes towards the euro over time in Germany using longitudinal micro-data from the German Socio Economic Panel Study. We observe that a large part of the German population was worried about the new currency both before and after its introduction. Social psychological theories provide insight into these attitudes. Concerns regarding the euro are apparently connected with problems in handling the new currency and with the press coverage of price rises. For these reasons, future EMU member states should prepare their populations better for these challenges.     

On the Critical Value Behaviour of Multiple Decision Procedures

In this paper we investigate the asymptotic critical value behaviour of certain multiple decision procedures as e.g. simultaneous confidence intervals and simultaneous as well as stepwise multiple test procedures. Supposing that n hypotheses or parameters of interest are under consideration we investigate the critical value behaviour when n increases. More specifically, we answer e.g. the question by which amount the lengths of confidence intervals increase when an additional parameter is added to the statistical analysis. Furthermore, critical values of different multiple decision procedures as for instance step-down and step-up procedures will be compared. Some general theoretic results are derived and applied for various distributions.     

Effects of sterile insect releases on a population under predation or parasitism

Summary A continuous-time differential equation model was constructed which describes the population dynamics of a predator prey system in which sterile prey are released in a program designed to eradicate or reduce the prey population. It was found that the dynamics of the system behave quite differently when predators are present. Two conditions were found which have differing implications for the control program. If the predators still exist when the wild prey population declines to extinction, then the SIRM is assisted by the predators, sometimes to a considereble extent. If the predators decline to extinction before the wild prey population goes extinct, then the predators may or may not assist the SIRM depending on the parameters of the system. If the predators do assist the SIRM, then a potentially dangerous situation exists in which an explosion of the prey population could occur after the predators go extinct. Predator polyphagy would probably minimize this danger of an explosion since it would stabilize the predator population.     

Social Conflict: Implications for Casework Practice

Summary The concept of social conflict is examined in terms of its usefulnessin refining and extending social casework theory. Attentionis given to the influence of the homeostatic approach to caseworkpractice versus an approach utilizing a conflict orientation.Primary emphasis is given to Coser's sociological theory ofconflict in an effort to discover heuristic concepts which areconsidered to be applicable in the practice of social casework.Specifically, seven of Coser's original sixteen propositionsrelated to conflict theory have been selected for analysis.It is concluded that a conflict orientation would serve to clarifythe functional aspects of conflict as they relate to the dyadiccasework relationship
