Electronic performance self-monitoring and engineered labor standards for “man-up” drivers in a distribution center

Electronic Performance Monitoring (EPM) represents the future of performance feedback where supervisors can electronically monitor the amount and quality of work an employee is producing and have objective indicators of employee performance immediately available and visible. In this study, immediate performance feedback and self-monitoring was delivered to employees in the warehouse on wireless vehicle-mounted computers. Order picking performance for “man-up” drivers (N = 10) was improved by three cases per hour per person in an auto-parts after-market distribution center when an intervention package that included the depiction of goal times and immediate performance feedback on wireless vehicle-mounted computers and a newly developed engineered labor standard (ELS). The implications of these findings and limitations are discussed in terms of operational and ethical issues regarding EPM in large industrial settings.

Ambiguous probabilities: when does p=0.3 reflect a possibility,and when does it express a doubt?

Verbal phrases denoting uncertainty are usually held to be more vague than numerical probability statements. They are, however, directionally more precise, in the sense that they are either positive, suggesting the occurrence of a target outcome, or negative, drawing attention to its non‐occurrence. A numerical probability will, in contrast, sometimes be perceived as positive and sometimes as negative. When asked to complete sentences such as ‘The operation has a 30% chance of success, because’ some people will give reasons for success (‘the doctors are expert surgeons’), whereas others will give reasons for failure (‘it is a difficult operation’). It is shown in two experiments that positive reasons are given more often than negative ones, even for p values below 0.5, especially when the probability is higher than expected, and the target outcome is non‐normal, undesirable, and phrased as a negation. We conclude that the directionality of numerical probabilities (as opposed to verbal phrases) is context‐dependent, but biased towards a positive interpretation.

Causal explanations for lack of pregnancy applying the common sense model of illness representation to the fertility context

Abstract

Objectives: The current study explored causal explanations for lack of pregnancy and association with help-seeking behaviour. Differences based on gender and country Human Development Index were examined.

Design: A mixed method design was used.

Main outcome measures: Data were drawn from the International Fertility Decision-Making Study, a cross-sectional study of 10,045 individuals (1690 men; 8355 women) from 79 countries. Respondents rated to what extent they believed their lack of pregnancy was due to something they or their partner had done/not done or other factors and described their reasons for making this rating.

Results: Respondents were aged 18–50 (M?=?31.83) years, partnered and had been trying to achieve a pregnancy/father a child for over six months (M?=?2.8 years). Men and women primarily believed their lack of pregnancy was due to medical problems or chance/bad luck. Thematic analysis of textual responses from 29.7% of the sample found that respondents focused on their personal experience or a salient life event when describing the cause of their lack of pregnancy. Women expressed more regret and helplessness about causes than men. Significant country differences were observed.

Conclusions: Individuals may develop inaccurate causal explanations based on their personal experiences. Access to accurate information is necessary to facilitate timely help-seeking.     

Learning potential and anxious tendency: Test anxiety as a bias factor in educational testing

Abstract

Contrary to conventional educational testing, in so-called dynamic assessment subjects are allowed to consult help during testing or are offered prior training. The differential results of both testing procedures are sometimes ascribed to the idea that dynamic tests reflect the breadth of the zone of proximal development on top of independent achievement. Alternative explanations claim that conventional tests are more strongly biased towards various characteristics of persons, which have a negative influence on performance, when compared to dynamic tests. In this study, it was hypothesised that static as well as dynamic assessment is biased towards anxious tendencies of subjects, but the former more strongly than the latter. In order to investigate this supposition, the performance of subjects on dynamic and static tests was systematically compared and related to measures of test anxiety in a longitudinal experiment. In the experiment, repeated measures of independent mathematics achievement as well as mathematics learning potential were gathered among students of secondary education in the Netherlands. Prior to every mathematics test, subjects filled out a test anxiety questionnaire. After every mathematics test, subjects filled out a general state anxiety questionnaire. The participating subjects were students from secondary education, either preparing for higher vocational training or university, aged approximately 15 years on average.

The results of the experiment showed that lack of self-confidence is an important constituent factor of test anxiety, apart from worry and emotionality. The data supported the assumption that such testing procedures are less biased towards anxiety than conventional tests, but it was not established that dynamic testing procedures render results that are not biased by test anxious tendencies.     

Interdisziplinarität und Wissensentwicklung

Interdisciplinarity and the Development of Knowledge. The author is engaged in the question how to explain the development of scientific meanings of facts which does not coincide with producing them rather with processes of the scientists' public communication. So long as the facts are adjustable to the conventional theories of those discipline which the researcher belongs to this connection does not reveal perfectly clear. More instructive is a consideration of so-called anomalies. The author demonstrates with an example of the history of science that researchers in case of new phenomena use to borrow concepts from other disciplines for resolving the interpretative problems. It emerges a loose net-work of concepts. In this way the researchers are producing a disciplinary mixed public at the same time. This process is seen as an important phase of the development of new theories and, complementary, new disciplines.     

Young children's psychological explanations and their relationship to perception‐ and intention‐understanding

The present study examined two key aspects of young children's ability to explain human behaviour in a mentalistic way. First, we explored desires that are of a level of difficulty comparable with that of false beliefs. For this purpose, the so‐called ‘alternative desires’ were created. Second, we examined how children's psychological explanations are related to their understanding of perception and intention. A perception‐understanding task, an intention‐understanding task and a psychological‐explanation task were administered to 80 three‐year‐olds. Results offer support for the thesis that the level of difficulty of belief and desire explanations is comparable. Moreover, children's psychological explanations are related to their understanding of perception and intention. The results lend support to the idea that mentalistic explanations are an explicit manifestation of children's level of theory of mind. Copyright © 2008 John Wiley & Sons, Ltd.     

CAN WE STILL TALK ABOUT “TRUTH” AND “PROGRESS” IN INTERDISCIPLINARY THINKING TODAY?

On a cultural level, and for Christian theology as part of a long tradition in the evolution of religion, evolutionary epistemology “sets the stage,” as it were, for understanding the deep evolutionary impact of our ancestral history on the evolution of culture, and eventually on the evolution of disciplinary and interdisciplinary reflection. In the process of the evolution of human knowledge, our interpreted experiences and expectations of the world (and of the ultimate questions we humans typically pose to the world) have a central role to play. What evolutionary epistemology also shows us is that we humans can indeed take on cognitive goals and ideals that cannot be explained or justified in terms of survival‐promotion or reproductive advantage only. Therefore, once the capacities for rational knowledge, moral sensibility, aesthetic appreciation of beauty, and the propensity for religious belief have emerged in our biological history, they cannot be explained only in biological/evolutionary terms. Finally, in this way a door is opened for seeing problem solving as a central activity of our research traditions. As philosophers of science have argued, one of the most important shared rational resources between even widely divergent disciplines is problem solving as the most central and defining activity of all research traditions. As will become clear, the very diverse reasoning strategies of theology and the sciences clearly overlap in their shared quests for intelligible problem solving, including problem solving on an empirical, experiential, and conceptual level.
