Non‐standard work schedules and retention in the entry‐level hourly workforce

Non‐standard work schedules involve work outside the Monday–Friday daytime hours. Although research has heavily studied the health and family effects of such schedules, few studies have investigated their relationship to retention. We draw from Maertz and Campion's discussion of motivational forces that influence turnover to propose that employees on non‐standard schedules are more likely to quit their employer because of general job dissatisfaction and because of normative pressures from family and/or friends. Specifically, we hypothesized that employees on day shifts or weekday only schedules would remain with their employer longer than those who work on nonday shifts or on the weekends. We also hypothesized that perceived employment mobility would moderate the effects of non‐standard schedules on retention length. Hypotheses were tested among 3,178 retail employees who worked five different distinct shift arrangements and different weekday/weekend schedules. Cox regression analyses indicated that, as hypothesized, employees working nonday shifts or schedules including weekends remained with their employer for a shorter duration of time than employees not on such schedules. Perceived mobility moderated the schedule–turnover relationship, though not in the hypothesized manner. We discuss the theoretical and practical implications of these findings for work schedule assignment and retention strategies.     

Varying the importance of a prospective memory task: differential effects across time- and event-based prospective memory

Only few studies have addressed the issue of task importance in prospective memory. Most of them, but not all, have shown that perceived task importance does improve prospective memory performance. However, there is little understanding of (1) the conditions under which importance of the prospective memory task makes a difference in performance and (2) the mechanisms by which perceived task importance has an effect on prospective memory performance. The present study reports two experiments that manipulate task importance in a time-based and an event-based prospective memory paradigm. Results show that importance has an effect on the time-based but not on the event-based task. Further analyses of the performance in the cover tasks as well as the monitoring behaviour indicate that importance improves prospective memory to the degree the task requires the strategic allocation of attentional resources.     

Factor Structure of the Illness Intrusiveness Rating Scale in Patients Diagnosed with Anxiety Disorders

The Illness Intrusiveness Rating Scale (IIRS) is a measure designed to assess the impact of illness on various domains of functioning (G. M. Devins, 1994). In anxiety disordered patients, illness intrusiveness ratings are higher than those of chronically ill medical patients, suggesting that the IIRS may have a different underlying structure in a sample of individuals with anxiety disorders. To examine this possibility, IIRS items were submitted to an exploratory and confirmatory factor analysis in 2 samples (total N = 294). These solutions were compared to solutions in chronically ill populations from a previous study. In the exploratory analysis, both a one-factor and a three-factor solution were identified, accounting for 42 and 61% of the variance, respectively. Confirmatory analyses showed adequate similarity between the three-factor structure of the IIRS from a medically ill population and the current three-factor structure, suggesting that elevated IIRS scores in anxiety disordered samples cannot be explained simply by a different structure of the instrument.     

User-controlled photographic animations, photograph-based questions, and questionnaires: Three Internet-based instruments for measuring drivers’ risk-taking behavior

The Internet has been exploited successfully in the past as a medium for behavioral research. This paper presents a series of studies designed to assess Internet-based measures of drivers’ risk-taking behavior. First, we compared responses from an Internet sample with a traditional pencil-and-paper sample using established questionnaire measures of risk taking. No significant differences were found. Second, we assessed the validity of new Internet-based instruments, involving photographs and photographic animations, that measured speed, gap acceptance, and passing. Responses were found to reflect known demographic patterns of actual behavior to some degree. Also, a roadside survey of speeds was carried out at the locations depicted in the photographic measure of speeding and, with certain exceptions, differences between the two appeared to be constant. Third, a between-subject experimental manipulation involving the photographic animation measure of gap acceptance was used to demonstrate one application of these techniques.     

A Method for Comparing Knowledge Structures Concerning Their Adequacy

A knowledge domain is represented in knowledge space theory by a finite set Q of problems. The knowledge of a subject in the domain is described by the subset of problems from Q that the subject is able to solve. The set of all possible knowledge states of subjects is called the knowledge structure on Q. A crucial problem is how a hypothetical knowledge structure, obtained for example by querying an expert, can be evaluated empirically. We describe a method for comparing two knowledge structures concerning their ability to describe a set of empirically observed response patterns. Our comparison method is tested in two simulation studies. The results of these studies show that the method is highly accurate in its evaluation of knowledge structures.

Ambivalence,conflict, and decision making: attitudes and feelings in Germany towards NATO's military intervention in the Kosovo war

Two hundred and thirty‐four persons were surveyed to assess personality aspects (action versus state orientation, need for cognition, faith in intuition) and emotional aspects of their attitudes towards the NATO military intervention in the Kosovo war in the spring of 1999. Additionally, in an imagined scenario they were asked to decide whether they would sign a petition addressed to the German government protesting against military intervention. Three ways of dealing with this decision were differentiated: (1) decisive action, (2) avoiding the decision conflict, and (3) elaborating the decision problem with the goal of building up feelings to guide action (amplification). Correlations between the variables were evaluated using path analysis in order to predict the decision strategy from personality dimensions and attitude variables (ambivalence, involvement). High action orientation caused low attitude ambivalence and high personal involvement in the topic. Strong ambivalence prevented swift action and supported a tendency towards elaboration and amplification of feelings. Involvement had a favorable effect on action readiness and a negative effect on conflict‐avoiding strategies. Moreover, it moderated the effects of ambivalence on the preference for conflict management strategies. The results confirm theoretical approaches that stress the importance of affect for acting and deciding. Copyright © 2001 John Wiley & Sons, Ltd.     

A computer simulation of the argument from disagreement

In this paper we shed new light on the Argument from Disagreement by putting it to test in a computer simulation. According to this argument widespread and persistent disagreement on ethical issues indicates that our moral opinions are not influenced by any moral facts, either because no such facts exist or because they are epistemically inaccessible or inefficacious for some other reason. Our simulation shows that if our moral opinions were influenced at least a little bit by moral facts, we would quickly have reached consensus, even if our moral opinions were affected by factors such as false authorities, external political shifts, and random processes. Therefore, since no such consensus has been reached, the simulation gives us increased reason to take seriously the Argument from Disagreement. Our conclusion is however not conclusive; the simulation also indicates what assumptions one has to make in order to reject the Argument from Disagreement. The simulation algorithm we use builds on the work of Hegselmann and Krause (J Artif Soc Social Simul 5(3); 2002, J Artif Soc Social Simul 9(3), 2006).
