In this study, the relationships among boredom proneness, job boredom, and counterproductive work behaviour (CWB) were examined. Boredom proneness consists of several factors, which include external stimulation and internal stimulation. Given the strong relationships between both the external stimulation factor of boredom proneness (BP-ext) and anger as well as the strong relationship between trait anger and CWB, we hypothesized that examining BP-ext would help us to better understand why employees commit CWB. Five types of CWB have previously been described: abuse against others, production deviance, sabotage, withdrawal and theft. To those we added a sixth, horseplay. Using responses received from 211 participants who were recruited by email from throughout North America (112 of them matched with co-workers), we found support for our central premise. Indeed, both BP-ext and job boredom showed significant relationships with various types of CWB. The boredom proneness factor also moderated the relationship between job boredom and some types of CWB, suggesting that a better understanding of boredom is imperative for designing interventions to prevent CWB.  相似文献

During childhood and adolescence, family meal frequency has been found to have an inverse relationship with disordered eating behaviour. Also, family interactional patterns differ in families where there is a child with and without an eating disorder. This paper examines the relationship between family mealtime interactions during childhood and adolescence and eating disorder behaviour through a systematic review of the literature. The method was an asystematic electronic search of PsycInfo, Medline and Web of Knowledge undertaken in April 2012. Ten studies demonstrated a significant relationship between family mealtime interactions and disordered eating behaviour. Families where there is a child with an eating disorder display less positive interactions during mealtimes. While the findings can be linked to family based treatment for anorexia nervosa there is a need for prospective research in this area.  相似文献

One of the basic functions of an MRP system is to issue rescheduling messages that urge the planner tospeed up or slow down open orders. It seems in practice that these messages are not used at all by planners. This is mostly due to the inaccuracy of MRP, that more or less ignores safety time, safety stocks and lotsize flexibility in the calculation of reschedule-in messages. Reschedule-out messages are usually ignored because planners do not see the value of the message. Other reasons for not adhering to rescheduling messages are a lack of maintenance of MRP parameters or simply the wrong use of the MRP function. In the future, MRP rescheduling functionality will be used even less than today, due to the changing role of MRP within the planning framework. With the uprise of finite capacity scheduling packages, MRP is being pushed one level upward in the planning hierarchy. This means that rescheduling functionalities for the short term will become completely obsolete in MRP systems.  相似文献

This article examines Heidegger’s reading of Ernst Jünger’s 1932 Der Arbeiter by making appeal not only to Heidegger’s remarks on the work (and its associated text “Die totale Mobilmachung”) scattered in various texts, but by concentrating on Heidegger’s now‐available seminar notes and marginal notes to his actual copy of the text. Heidegger held two seminars on Der Arbeiter, one shortly after its publication and one in 1938, which show his close confrontation not only with Jünger’s reading of Nietzsche, but also Heidegger’s own Nietzsche examination. The article shows how Heidegger distinguishes himself from Jünger by, on the one hand, seeing Der Arbeiter as very much a product of its time and, on the other, identifying a prescience in Nietzsche of a Europe and planetary phenomenon (globalisation) yet to come. This is accomplished in the naming of the triad of Bolshevism, fascism (Nazism), and Americanism metaphysically as the singularity of “world democracy”, and as an entirely nihilistic phenomenon. The article therefore relates the confrontation of these two thinkers with the third (Nietzsche) to issues of the demand for justice, democracy, and the will to power in contemporary economic and political developments, as well as to wider themes in Heidegger’s thought of the end (or consummation) of metaphysics, the will to power, and valuation.  相似文献

The concept of exposure is central to chemical risk assessment and plays an important role in communicating to the public about the potential health risks of chemicals. Research on chemical risk perception has found some indication that the model lay people use to judge chemical exposure differs from that of toxicologists, thereby leading to different conclusions about chemical safety. This paper presents the results of a series of studies directed toward developing a model for understanding how lay people interpret the concept of chemical exposure. The results indicate that people's beliefs about chemical exposure (and its risks) are based on two broad categories of inferences. One category of inferences relates to the nature in which contact with a chemical has taken place, including the amount of a chemical involved and its potential health consequences. A second category of inferences about chemical exposure relates to the pragmatics of language interpretation, leading to beliefs about the motives and purposes behind chemical risk communication. Risk communicators are encouraged to consider how alternative models of exposure and language interpretation can lead to conflicting conclusions on the part of the public about chemical safety.  相似文献

This study examined the antecedents of job strain (emotional exhaustion, health complaints) and withdrawal behaviour (e.g. lowered organizational commitment) among a cross-sectional sample of 131 academic staff members of the law department of a large Dutch university. Conservation of resources theory (Hobfoll, 1989) provided the theoretical background for this study. Strains and withdrawal behaviours were expected to be most prominent among those who reported having few resources and/or who reported high job demands. Structural equation modelling revealed that this was indeed the case. As predicted, differential patterns of effects emerged for job demands and job resources. Analysis of the effects of four job-specific stressors revealed that especially the structural aspects of a staff member's teaching task (e.g. the number of students in their classes) contributed strongly to perceived job demands. Theoretical and practical implications of the study are discussed.  相似文献

The notion of “value” developed over the ages to connote the variability of price. It was spontaneously assumed that if price varies, there must be an underlying, more constant essence of which price is a phenomenal manifestation. Both seminal and representative of various attempts at establishing the foundations of the concept of value, Adam Smith hesitated between the “additive theory of value” and the embedded work-time interpretation. In the latter, expanded by Ricardo and Marx, value expresses quantities of work-time embedded in a commodity. Smith's attempt aborts when he fails to find the means for comparing the various qualities of various work-times. To succeed, Smith's embedded work-time interpretation of value needs to be complemented by Aristotle's theory of price, where the quality of a piece of work-time equates with the quality of its performer in the social order. Price in Aristotle expresses the relative status of purchaser and seller as the rate at which their respective work-times are traded. In so doing, and long before Marx, Aristotle identifies the economy with the political system. Le concept de «valeur» est apparu historiquement comme l'envers objectif du prix. La nature changeante de celui-ci étant alors envisa-gée comme l'expression phénoménale d'une essence plus permanente appelée «valeur». Pionnier de la réflexion sur la valeur, et représen-tatif des tentatives ultérieures pour la fonder, Adam Smith propose deux théories entres lesquelles il hésite: l'interprétation dite additive et l'interprétation en termes de temps de travail incorporé. Cette dernière, reprise ensuite par Ricardo et Marx, suppose que la valeur reflète les temps de travail incorporés à la marchandise. Smith échoue dans sa tentative en raison de l'impossibilité de fixer des critères permettant de comparer la qualité de différents temps de travail. Pour réussir, la théorie de la valeur d'Adam Smith doit être complétée par la théorie du prix d'Aristote. Pour lui, la qualité d'un temps de travail reflète la qualité dans l'ordre social de celui qui l'effectue. Le prix pour Aristote exprime le statut réciproque de l'acheteur et du vendeur, dont le rapport du prix marchand de leur temps de travail fournit la mesure. Ainsi, et longtemps avant Marx, Aristote assimile l'ordre économique à l'ordre politique.  相似文献
