Centering around anticipative and reactive capabilities of firms, accurate response is an important supply‐side strategy to deal with demand uncertainty. Clearly, the structure of the possible reaction will crucially influence the optimal anticipative decision making. In this article, we extend the existing literature in this area by including a new reactive capability, namely the utilization of refurbished consumer returns from early sales to react to demand later in the selling season. Because consumer returns depend on previous sales, there is also a direct link to the anticipative supply decision. We capture this effect in a newsvendor‐type model and provide both analytical and numerical insights into the optimal anticipative and reactive decisions as well as the value of refurbishing in terms of the retailer's expected profitability.  相似文献

This study aims to assess the predictive value of two sets of variables, self-attributions, and coping behaviors, on sexually abused (SA) teenagers' functioning, while controlling for abuse-related and family variables. A total of 103 female adolescents completed self-report measures to assess their psychological functioning in terms of anxiety, depression, PTSD, sexual concerns, dissociation, anger, their self-injurious behaviors, antisocial behaviors, and drug use. After controlling for SA and family characteristics, final regression models indicate that attributions and coping behaviors explained between 22% and 39% of additional unique variance for seven out of the nine measures of adolescent functioning. Attributions and coping behaviors did not significantly explain additional variance for scores of antisocial behaviors and drug use. Personal attributions of blame for negative events were the strongest predictors of adolescents' functioning. Implications for future research and interventions are highlighted.  相似文献

Background Most adults gamble recreationally yet few studies have systematically investigated for gender-related differences in recreational gamblers.Methods Logistic regression analyses were performed on data from a nationally representative sample of respondents from the 1998 Gambling Impact and Behavior Study. Results Female gamblers versus non-gamblers were more likely to report use of alcohol and drugs. Male gamblers versus non-gamblers were more likely to report alcohol use and abuse/dependence, any substance abuse/dependence, and lifetime incarceration. An analysis of gambling by gender group interaction effects did not identify significant differences in health-related measures. Male as compared with female gamblers reported beginning gambling earlier, experiencing higher past-year maximal losses and wins, and finding favorite and engaging in different types of gambling.Conclusions Despite heavier gambling in male as compared with female recreational gamblers, similar mental health functioning was observed in female and male past-year recreational gamblers. Types of gambling problematic for men and women are reflected in the gambling preferences of recreational gamblers.  相似文献

Opened in 1946, the Linda Hall Library in Kansas City, Missouri, is world renowned for its collections in science, engineering, and technology. Just as well known is the strong user orientation of its dedicated staff. While the library certainly collects all types of materials, including books, patent specifications, engineering standards, maps, and more, a particularly strong emphasis is placed on the collection of current journals. The library, a privately funded public library, is situated on fourteen acres surrounded by the University of Missouri-Kansas City, although there is no affiliation with that institution. Serials Review made a visit on a lovely spring day in June, as the day lilies and other flowers were in full riot.  相似文献
