Women's rapid entry into medicine raises important questions about change in this historically male-dominated profession. In addition to shifting the gender balance, do increasing numbers of women signal a more fundamental change in the way in which medicine is organized and practised? A growing body of research suggests such change. Yet there is continuing controversy about the meaning of observed gender differences in practice, whether they reflect an essentially pragmatic response to women's dual workload of family and career, or whether they are the result of underlying differences in attitudes, values and orientations. This article uses data from a survey of a recent cohort of family physicians in Ontario, Canada, to document the extent of gender differences and similarities in medical practice, and their interrelationships to family situation, political attitudes and patient care attitudes. The results show that seemingly related differences in practice are accounted for in different ways: while some are associated with differences in family situation, others are tied to attitudes, while others are a function of gender alone. The results also reveal gender similarities which do not suggest that women are becoming more like men, but that men, and the profession as a whole are changing. We would emphasize the importance of interpreting gender differences and similarities within a broader conceptual understanding of change in the profession. 相似文献

Conclusion The political environment faced by U.S. unions has changed substantially over the past decade. The cost of election campaigns
has increased dramatically and many interest groups have become actively involved in election financing. More importantly,
the election of a Republican majority to Congress in 1994 caused a major change in the nature of unions' interactions with
Washington legislators. Organized labor has faced a barrage of bills aimed at reducing the power of unions and minimizing
their political involvement. Such efforts have also occurred across the country as conservative groups have attempted to qualify
referenda that limit unions in some way. At a time when unions must organize new workers to survive as a viable force in society,
these political challenges are especially serious matters. 相似文献

When presented as graphical illustrations, regression surface confidence bands for linear statistical models quickly convey detailed information about analysis results. A taut confidence band is a compact set of curves which are estimation candidates for the unobservable, fixed regression curve. The bounds of the band are usually plotted with the estimated regression curve and may be overlaid by a scatter-plot of the data to provide an integrated visual impression. Finite-interval confidence bands offer the advantages of clearer interpretation and improved efficiency and avoid visual ambiguities inherent to infinite-interval bands. The definitive characteristic of a finite-interval confidence band is that it is only necessary to plot it over a finite interval in order to visually communicate all its information. In contrast, visual representations of infinite-interval bands are not fully informative and can be misleading. When an infinite-interval band is plotted, and therefore truncated, substantial information given by its asymptotic behavior is lost. Many curves that are clearly within the plotted portion of the infinite interval confidence band eventually cross a boundary. In practice, a finite-interval band can always be easily obtained from any infinite-interval band. This article focuses on interpretational considerations of symmetric confidence bands as graphical devices. 相似文献

We built three simulation models that can assist rail transit planners and operators to evaluate high and low probability rail‐centered hazard events that could lead to serious consequences for rail‐centered networks and their surrounding regions. Our key objective is to provide these models to users who, through planning with these models, can prevent events or more effectively react to them. The first of the three models is an industrial systems simulation tool that closely replicates rail passenger traffic flows between New York Penn Station and Trenton, New Jersey. Second, we built and used a line source plume model to trace chemical plumes released by a slow‐moving freight train that could impact rail passengers, as well as people in surrounding areas. Third, we crafted an economic simulation model that estimates the regional economic consequences of a variety of rail‐related hazard events through the year 2020. Each model can work independently of the others. However, used together they help provide a coherent story about what could happen and set the stage for planning that should make rail‐centered transport systems more resistant and resilient to hazard events. We highlight the limitations and opportunities presented by using these models individually or in sequence. 相似文献

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
