We demonstrate that universally redeemed rebates can increase manufacturer profits by reducing the incentives of downstream retailers to hoard inventories when optimal wholesale prices vary predictably over time. By bypassing retailers and making direct contracts with buyers, the manufacturer can increase the variations in effective prices paid by consumers without concomitantly creating larger incentives for retailers to hold inventories. During profitable, high-demand periods, manufacturer revenues are ordinarily constrained by'competition'from retailer inventories, thus limiting profits. However, by selectively offering rebates to consumers while maintaining high wholesale prices, low-demand periods can be accommodated without inducing retailer hoarding. 相似文献

This analysis extends previous research on fear of crime by focusing on neighborhood racial composition as a salient predictor of fear of criminal victimization. Although its main effect was not strongly associated with fear, a multiplicative interaction term for neighborhood racial composition by race (WRAC) suggests that whites living in mostly black neighborhoods are the most fearful. Only sex and size of community were stronger predictors of fear. A parsimonious model including the variables sex, age, community size, and the interaction term WRAC is found to explain twenty-six percent of the variance in fear for personal safety on neighborhood streets at night. 相似文献

Electronics has produced a succession of remarkable accomplishments within the lifetime of living men. Yet, new developments in the field are so vast and exciting that they may be viewed as the advent of an Electronic Revolution comparable to the Industrial Revolution. 相似文献

Many studies have examined the relations between drug use and sexual behaviors; however, few have utilized episodic data to examine the co-occurrence of both behaviors within the same episode. This study surveyed 403 racially and ethnically diverse gay, bisexual, and other young men who have sex with men (YMSM; ages 18–29) in New York City. Men were surveyed about their sexual behavior and concurrent use of illicit substances and alcohol during their most recent sexual encounter with their main and/or casual partner(s). Logistic regression models were built to analyze predictors of unprotected oral and anal intercourse with main and casual partners. Results suggest that use of inhalant nitrates and alcohol increased the odds of men engaging in unprotected receptive anal intercourse (URAI) and men who identified as middle or high socioeconomic status (SES) were at lower odds of engaging in URAI with their main partner. Use of other illicit substances was not associated with unprotected sexual intercourse. These findings indicate a need to further consider the role of licit substances used by YMSM as a means of further reducing the incidence of HIV infection in this population. In addition, the high rates of unprotected anal intercourse among men reporting a main partner has the potential to be a significant source of HIV risk, and should be further explored among YMSM. 相似文献

The relationships between mental health, substance use, and sexual behaviors among gay and bisexual men in a sample of 450 club drug-using men from New York City were examined using syndemics theory. Risk scores for each participant were based on variables measuring substance use and mental health burden. Participants with higher risk scores were significantly more likely to engage in risk behaviors. Risk taking was also explained by serosorting, suggesting that syndemics theory in and of itself, while significant in explaining risk, is not sufficient. These findings suggest we need to understand the interplay between social, emotional, and cognitive factors to understand sexual risk taking. 相似文献

This qualitative, grounded theory study investigated 11 families who reported having successfully integrated into their family unit at least one older/special needs adoptee. The theory that emerged through the constant comparative methodology consisted of two categories (Decision to Adopt and Adjustment) and a core category (Developing a Sense of Family). The two categories and core category comprised a process that was informed by the Family Narrative Paradigm and culminated in the successful integration of the child or children into the existing family unit. Parental perceptions that appeared to facilitate this process included: (a) finding strengths in the children overlooked by previous caregivers, (b) viewing behavior in context, (c) reframing negative behavior, and (d) attributing improvement in behavior to parenting efforts. 相似文献

Adequate consideration cannot be given to the subject of inflation accounting without a rigorous reappraisal of the nature and usefulness of published financial statements. It is argued that much fundamental research is a necessary prerequisite for the evaluation of methods of accounting in a period of inflation. Such research should begin with a consideration of the purposes to be served by the publication of financial statements. A framework is presented for such fundamental research and the results of some preliminary work outlined to assess the usefulness of financial statements in providing information to assist investors to make investment decisions. The use of financial statements by investors for this purpose is one of a number of possible objectives for financial statements. 相似文献
