The Employment Status of Immigrant Women: The Case of Sweden1

This article presents an exploration of the employment status of various groups of immigrant women in the Swedish labor market in the period 1970–1995. Since employment is one of the key components for the integration of immigrants, it is interesting to study what factors determine whether or not immigrants become employed after entering Sweden. Numerous studies have analyzed the labor market integration of immigrant men, whereas the integration of women still has received less attention (Ekberg, 1983, 1991; Hammarstedt, 2001; Scott, 1999). This study can be seen as a contribution to an increase in the knowledge of the labor market integration of female immigrants in Sweden.     

Public Concern About Industrial Hazards

In this paper we propose adopting a noncognitive perspective for the understanding of people's anxiety or, its opposite, feelings of security about living near hazardous industrial facilities. Results of our empirical investigations among residents of a heavily industrialized area indicate that at least four qualitatively different response patterns exist: the Secure, the Accepting, the Defensive, and the Vigilant response. In this order manifest anxiety increases, which increase is shown to be a function of the assessment of the threat, of the opportunities for personal control (specific), and of hope (generalized) to bring about a better environment by one's own action. As an application of the usefulness of this typology we discuss the various explanations for the often-observed male/female difference in anxiety regarding industrial threat.     

The Timing of Labour Reallocation and the Business Cycle: Evidence for The Netherlands

In this paper we study the cyclical behaviour of job and worker flows in The Netherlands. We find that job flows move counter‐cyclically while worker flows move acyclically. The persistence of newly created jobs is strongly pro‐cyclical while the persistence of destroyed jobs is strongly counter‐cyclical. We also examine the relative importance of aggregate and sectoral versus idiosyncratic shocks. We find both shocks to be negatively correlated and idiosyncratic shocks to be somewhat more important in explaining the time variation of job reallocation. Finally, we find that gross job flows account for about one‐third of the worker flows. The remainder reflect churning.     

Exploring and Adapting a Conceptual Model of Sexual Positioning Practices and Sexual Risk Among HIV-Negative Black Men Who Have Sex With Men

Estimates show a 50% lifetime human immunodeficiency virus (HIV) risk among Black men who have sex with men (BMSM) in the United States(U.S.). Studying the dynamics of sexual positioning practices among BMSM could provide insights into the disparities observed among U.S. groups of men who have sex with men (MSM). This study explored sexual positioning dynamics among HIV-negative BMSM and how they aligned with a theoretical model of sexual positioning and HIV/sexually transmitted infection (STI) risk among MSM. In-depth qualitative interviews were conducted with 29 HIV-negative BMSM between ages 25 and 35 in Los Angeles. Comments related to sexual behaviors were reviewed for relevance regarding oral or anal sexual positioning practices. Data presented represent the range of themes related to decision making regarding sexual positioning. Personal preference, partner attraction, HIV avoidance, and feeling obligated to practice partner preferences influenced sexual positioning. Drug use also affected decision making and was sometimes preferred in order to practice receptive anal intercourse. These variables build on the conceptual model of sexual positioning practices and sexual risk, and add understanding to the relationship between preferences, practices, and risk management. Future research on risk among HIV-negative BMSM should quantify the relative impact of personal preferences, partner attraction, partner type, compromise, and substance use on sexual positioning practices and risk.     

Changing Industrial Metabolism: Methods for Analysis

Research in the field of industrial metabolism traditionally has been focused on measuring and describing physical flows of economic systems. The metabolism of economic systems, however, changes over time, and measuring material flows is insufficient to understand this process. Understanding the relation between economic activities and material flows can help to unravel the socio-economic causes of these physical flows. Three issues are addressed: The importance of spatial scales and trade flows, empirical analysis of relations between economic development and material flows, and treatment of behaviour of and interactions between stakeholders. For each of these issues, methods for analysis are suggested.     

HOW LARGE ARE SEARCH FRICTIONS?

This paper shows that we can normalize job and worker characteristics so that, without frictions, there exists a linear relationship between wages on the one hand and worker and job type indices on the other. However, for five European countries and the United States we find strong evidence for a systematic concave relationship. An assignment model with search frictions provides a parsimonious explanation for our findings. This model yields two restrictions on the coefficients that fit the data well. Allowing for unobserved heterogeneity and measurement error, we find that reservation wages are 25% lower than they would be in a frictionless world. Our results relate to the literature on industry wage differentials and on structural identification in hedonic models. (JEL: J210, J300, J600, J230)     

Online reach correction in 6- and 11-month-old infants

The current study investigated the development of online reach control. Six- and 11-month-old infants reached for a toy while their hand position was tracked. The toy either remained stationary (baseline trials) or unexpectedly displaced left- or rightward during the reach (perturbation trials). To obtain a measure of online reach correction, we compared reaches in the perturbation trials to reaches in baseline trials using autoregression analysis. Infants of both age groups adjusted their reach trajectories in the direction of the displacement. Moreover, we divided the reaching movements into movement units, defined as the submovements of a reach between local minima in hand speed. Eleven-month-old infants adjusted their reach within the span of a single movement unit; corrections in 6-month-olds spanned multiple movement units. These results suggest that the reach control system has a rudimentary replanning capacity by 6 months of age, which, with age, further develops to a more sophisticated online control mechanism for ongoing reaches.
