This inquiry examines comparative trends in collaboration among scholars, both over several decades and for several scientific disciplines. Findings suggest that in sociology specifically and science generally the trend is toward greater collaborative scholarship. At the turn of the twentieth century, better than 90 percent of the articles appearing in major periodicals in physics, biochemistry, biology, and chemistry were sole authored. Today, over 95 percent of such articles are collaboratively published. Disciplines affiliated with the social and mathematical sciences have experienced similar monotonic increases in collaborative activity, albeit, at a slower rate. A discussion of plausible explanations is offered for this observed growth in scientific collaboration. 相似文献

Conclusion Although the high-wage doctrine — the belief that the level of aggregate demand is determined by the level of wage rates —
is most often associated with the Great Depression, the doctrine’s effects on wage policy go back at least two decades further.
Rather than having been a product of desperate times, the doctrine gained wide acceptance during the prosperous 1920s as businessmen
and economists, citing the success of Henry Ford's continuing high-wage policies, and the (supposedly counterproductive) wage
deflation that had marked the steep depression of 1920-21, applied the doctrine's demand-enhancing logic to push for an economy-wide
minimum wage.
The authors thank Fred Bateman, Don Bellante, Roger Garrison, Peter Klein, and Anthony Patrick O’Brien for thoughtful comments
and suggestions. 相似文献

The study investigated how two distinct perspectives apply to the role of gender in parents' memorials on The Compassionate Friends (TCF) electronic bulletin board; cyberspace as merely a mirror of societal gendered patterns of bereavement, and cyberspace as a medium or context in which societal gendered patterns of bereavement are neutralized. Data were evaluated to determine to what extent gender differences exist concerning instrumental versus intuitive styles of bereavement. Analytic categories used in assessing gender differences in parental bereavement style included the following: invoking spirituality, directing messages to the deceased, artistic expressions, and special powers accorded to the deceased. With some exceptions, the findings supported the perspective emphasizing the gender neutralizing aspects of cyberspace parental bereavement for the population studied. 相似文献

Product recovery operations in reverse supply chains face rapidly changing demand due to the increasing number of product offerings with reduced lifecycles. Therefore, capacity planning becomes a strategic issue of major importance for the profitability of closed‐loop supply chains. This work studies a closed‐loop supply chain with remanufacturing and presents dynamic capacity planning policies developed through the methodology of System Dynamics. The key issue of the paper is how the lifecycles and return patterns of various products affect the optimal policies regarding expansion and contraction of collection and remanufacturing capacities. The model can be used to identify effective policies, to conduct various “what‐if” analyses, and to answer questions about the long‐term profitability of reverse supply chains with remanufacturing. The results of numerical examples with quite different lifecycle and return patterns show how the optimal collection expansion/contraction and remanufacturing contraction policies depend on the lifecycle type and the average usage time of the product, while the remanufacturing capacity expansion policy is not significantly affected by these factors. The results also show that the collection and remanufacturing capacity policies are insensitive to the total product demand. The insensitivity of the optimal policies to total demand is a particularly appealing feature of the proposed model, given the difficulty in obtaining accurate demand forecasts. 相似文献

Many studies estimate individuals’ values for avoiding fatality risks; however, most value-of-statistical-life studies focus
on accident-related deaths. Consequently, little is known about preferences for avoiding other fatal risks, such as cancer.
Cancer may engender strong feelings of dread, leading to a “cancer premium,” but cancer latency periods may have the opposite
effect. Using a national survey, we elicit relative preferences for avoiding fatal cancer and auto-accident risks. We find
strong preferences for avoiding cancer risks. With a 5-year latency, they are valued roughly three times greater than immediate
accident risks, declining to 50% greater for a 25-year latency.

This paper develops the idea of animation in user interfaces designed for decision support systems (DSS), proposes a framework to investigate the efficacy of animation in these interfaces, and reports on a study that examined the effects of properties of animation specified by the framework. Based on a review of selected background literature, principal properties affecting the efficacy of animation in user interfaces designed for DSS are identified and the effects on decision quality of three of these properties are hypothesized. To evaluate these hypotheses, data was collected in a laboratory experiment involving two different tasks. The results for both tasks indicate that animation in user interfaces designed for DSS should employ parallel as opposed to sequential navigation interactivity techniques. The decision quality of subjects that used a parallel navigation technique was significantly greater than that of those that used a sequential navigation interactivity technique. The results regarding the efficacy of image abstraction and transition effects varied by task. For one task, decision quality was significantly greater for subjects that used realistic as opposed to abstract images, but decision quality did not vary by transition effect. For the other task, decision quality was significantly greater for subjects that used gradual as compared to abrupt transition, but image abstraction had no effect on decision quality. 相似文献

Recent advances in technology have created opportunities for firms to invest in expensive automated equipment designed to improve volume flexibility. Such investments are made on the basis that flexibility benefits the firm by increasing managerial control over output, reducing the risk of demand uncertainty, and improving productivity. The presumption is that these benefits will eventually translate to higher cash flows, appreciation in the firm's market value, and better return to shareholders. Yet, there is no managerially useful analytical framework for measuring this relationship. This study develops a model that uses contingent claims analysis to evaluate the effect of volume flexibility on the firm's value and to determine the optimal degree of automation that maximizes share value. The analysis is done by taking into consideration alternative demand characteristics, cost patterns, and the effectiveness of volume flexibility in increasing managerial control over output, reducing the risk of demand uncertainty, and improving productivity. 相似文献

Within the context of the international business literature on multinationality and performance we develop new data on the foreign presence and performance of large UK multinational enterprises (MNEs). There are 32 UK MNEs for which we can obtain data on both their degree of multinationality (measured by the ratio of foreign to total (F/T) sales) and their performance. Here, in addition to the traditional overall performance of the firm, shown as return on total assets, we use new data on the return on foreign assets (ROFA). We conduct analytical work to show the positioning of the UK MNEs in the ROFA and F/T sales space and provide regression results showing a linear relationship between multinationality and performance, using the new ROFA metric. 相似文献
