Barter transactions, conducted openly by established corporations, play an increasingly significant role in the U.S. economy. The model developed here helps explain why firms use barter and yields predictions concerning the circumstances under which barter is likely to occur. It is shown that when two firms barter goods used as inputs, price discrimination occurs. This price discrimination is hidden from the firms' other customers because the real values of the transacted goods to the barterers are different from the accounting prices used in the transaction. Since price discrimination that is observed by potential customers might have an adverse effect on the selling firm's future bargaining power, barter will have value as a means of hiding price discrimination. 相似文献

Current discussions within symbolic interaction point to a concern with (a) returning to Mead's original insights, (b) extending Meadian thought beyond the micro realm, and (c) linking Mead's ideas to constructive social action. These concerns complement an effort within contemporary Marxist literature to provide a systematic social psychology for understanding new forms of domination in capitalist society. In exploring the philosophical foundations of Mead and Marx, the authors identify fundamental similarities in their approaches to the relation between consciousness and community. The authors criticize the current attempts to synthesize Marx and Freud and call for a more thoroughly sociological approach. A Meadian reading of Marx, unlike the Marx-Freud synthesis, is consistent with sociological assumptions and points to the practical possibility of transformative social change through the interpersonal act. 相似文献

Online surveys are becoming increasingly popular for accessing less visible and decentralized populations, including bisexual, gay, lesbian and transgender (BGLT) populations. Advances in technology and convenience for the both the researcher and the participant have facilitated this trend. In this paper, we explore issues related to conducting BGLT survey research online, such as making decisions about survey formats, target populations and recruitment, compensation, access. 相似文献

The genogram is a structured method of taking a three-generational family history. This paper describes a variety of ways the clinician can use the genogram in addition to the standard uses described in the literature. It also demonstrates using the genogram as a quasi-projective technique which reveals unarticulated fears, wishes and values of the individuals comprising the family unit. Practical suggestions as to technique in creating genograms are offered, as well as a discussion of when, with whom and under what circumstances genograms should be undertaken. 相似文献

AbstractThe authors respond to an article on the role of the International Standard Serial Number (ISSN) as a manifestation (format) identifier of serials. They discuss some of the challenges that multiple manifestations present for the ISSN Network, some proposed solutions to this problem, and invite further input and dialogue on the topic.

ABSTRACT Employee financial wellness programs (EFWPs) are a new practice that may promote financial inclusion by making it easier for workers with low- and moderate-incomes (LMI) to access financial services. We examine the strengths and limitations of workplace financial counseling, credit-building services, and small-dollar loans, and describe community collaboration to promote employee financial wellness. Findings suggest that these services are reaching a population that experiences financial exclusion, though evidence is mixed concerning how these services help workers with LMI resolve key financial challenges. Community collaboration focused on employee financial wellness presents opportunities to advocate for higher wages and better benefits. 相似文献

AbstractObjective: Examine receptivity and motivation to use/quit tobacco among college students after viewing Truth ads. Participants: Random sample of 10,000 college students invited to complete online survey February 2016 (8.5% response rate). Methods: Quasi-experimental. Participants (N?=?854) watched four ads and answered survey items for each ad. Results: Students rated ad receptivity and decreased motivation to use tobacco higher for the Catmageddon ad than the others. Regardless of ad, men and current cigarette smokers reported lower receptivity. Younger age was associated with lower motivation to use tobacco for all ads. Tobacco users reported greater motivation to quit with the Catmageddon ad. Conclusions: College students were receptive to the Truth ads, and many indicated lower motivation to use tobacco. Men, older college students, and current cigarette smokers were less receptive to the ads, reinforcing the need to develop tailored campaigns to reach these subgroups. 相似文献

One of the most dynamic and fruitful areas of current health‐related research concerns the various roles of the human microbiome in disease. Evidence is accumulating that interactions between substances in the environment and the microbiome can affect risks of disease, in both beneficial and adverse ways. Although most of the research has concerned the roles of diet and certain pharmaceutical agents, there is increasing interest in the possible roles of environmental chemicals. Chemical risk assessment has, to date, not included consideration of the influence of the microbiome. We suggest that failure to consider the possible roles of the microbiome could lead to significant error in risk assessment results. Our purpose in this commentary is to summarize some of the evidence supporting our hypothesis and to urge the risk assessment community to begin considering and influencing how results from microbiome‐related research could be incorporated into chemical risk assessments. An additional emphasis in our commentary concerns the distinct possibility that research on chemical–microbiome interactions will also reduce some of the significant uncertainties that accompany current risk assessments. Of particular interest is evidence suggesting that the microbiome has an influence on variability in disease risk across populations and (of particular interest to chemical risk) in animal and human responses to chemical exposure. The possible explanatory power of the microbiome regarding sources of variability could reduce what might be the most significant source of uncertainty in chemical risk assessment. 相似文献
