A comparison of Swedish and US fathers' self‐reported use of parental discipline

Two samples (pairwise matched in terms of sex of child, age of child, and fathers' education) of fathers from Sweden (n = 50) and the US (n = 50) respectively were interviewed about their use of parental discipline when in conflict with their 38–66‐month‐olds. The results show that, compared with US fathers, Swedish fathers display a range of disciplining approaches from punitive reprimands (i.e., behaviour modification and physical punishment) to restrictive control approaches (i.e., verbal control and physical restraint). No difference was found between Swedish and US fathers in terms of their general tendency to assert compliance when their children misbehave. Copyright © 2002 John Wiley & Sons, Ltd.     

The potential of integrated modelling in conservation biology: A case study of the black‐footed albatross (Phoebastria nigripes)

Conservation biology aims at assessing the status of a population, based on information which is often incomplete. Integrated population modelling based on state‐space models appears to be a powerful and relevant way of combining into a single likelihood several types of information such as capture‐recapture data and population surveys. In this paper, the authors describe the principles of integrated population modelling and they evaluate its performance for conservation biology based on a case study, that of the black‐footed albatross, a northern Pacific albatross species suspected to be impacted by longline fishing     

Temporal pattern in number of staff on sick leave: the effect of downsizing

Summary.  The pattern of absenteeism in the downsizing process of companies is a topic in focus in economics and social science. A general question is whether employees who are frequently absent are more likely to be selected to be laid off or in contrast whether employees to be dismissed are more likely to be absent for the remaining time of their working contract. We pursue an empirical and microeconomic investigation of these theses. We analyse longitudinal data that were collected in a German company over several years. We fit a semiparametric transition model based on a mixture Poisson distribution for the days of absenteeism per month. Prediction intervals are considered and the primary focus is on the period of downsizing. The data reveal clear evidence for the hypothesis that employees who are to be laid off are more frequently absent before leaving the company. Interestingly, though, no clear evidence is seen that employees being selected to leave the company are those with a bad absenteeism profile.

Constrained allocation problems with single-peaked preferences: An axiomatic analysis

We introduce a new class of problems that contains two existing classes: allocation problems with single-peaked preferences and bankruptcy problems. On this class, we analyze the implications of well-known properties such as Pareto optimality, strategy-proofness, resource-monotonicity, no-envy, equal treatment of equals, and two new properties we introduce, hierarchical no-envy and independence of nonbinding constraints. Unlike earlier literature, we consider rules that allow free-disposability. We present characterizations of a rule we introduce on this domain. We relate this rule to well-known rules on the aforementioned subdomains. Based on this relation, we present a characterization of a well-known bankruptcy rule called the constrained equal awards rule. Received: 22 June 2000/Accepted: 21 March 2002 This paper is based on the first chapter of my Ph.D. thesis submitted to the University of Rochester. I wish to thank my advisor, William Thomson, for helpful comments and suggestions.

Comparative Journalism Research – An Overview

This overview focuses on the most common type of comparative journalism research, which is cross‐national comparative research. The overview presents a typology for different types of comparative journalism research, based on whether the research interest is in journalism as an activity or as a product; and, in the case of journalism as an activity, whether the interest is in the system level, the organizational level, or the individual level of journalism. The overview finds that the analysis of journalism on the individual level and of journalism as a product are the most common types of comparative research, whereas comparative analysis of journalism on the organizational level is much under‐studied.
