This paper addresses the questions of market penetration and locational conflict in a franchise system of distribution. The models developed provide a means to evaluate alternative scenarios and the effects of various franchise policies. It is shown that the market penetration and location goals of the members of a franchise system coincide only under a very limited set of circumstances.  相似文献

This article focuses on the contributions and, importantly, the limitations of subjective wellbeing (happiness/satisfaction) measures as indicators of broad population wellbeing and societal functioning. The popular practice of comparing happiness among countries gives a skewed view of how well their people are faring. Charting trends over time in happiness and mental health gives contradictory pictures of population wellbeing; even the responses to different questions within the same survey can yield very different findings. Asking people about their own lives and about social conditions produces contrasting results. These issues challenge the orthodox model of human development, which places Western liberal democracies at its leading edge. According to an alternative, psychosocial-dynamics, model, some, at least, may be societies in decline. Reconciling these views is no simple matter.  相似文献

Criminologists have long reported the existence of racial disparity in the criminal justice system, but the important question is why. While some argue that observed differences are a consequence of more criminal behavior among minorities, the weight of the evidence indicates that this is but a partial explanation. In this paper, we study data from a sample of juveniles to examine how racial differences in early police contact, and important social environments—family, school, and neighborhoods—affect later contact and arrests, controlling for self-reported delinquency. We find that early (in middle school) contact with police is an important predictor of later (high school) arrests. Also we found that, in addition to being male and living in a low-income family, children who have parents who have a history of arrest, who have experienced school disciplinary actions, who have delinquent peers, and who are in networks with deviant adults are more likely to have problems with law enforcement. These factors help to explain racial differences in police contacts and arrests.  相似文献

Abstract

Robert Cox developed a potent approach to studying world orders that is premised on the capacities of a special intellectual, the critical theorist, to discern social structures and the possibilities for their radical change in the future. While acknowledging the ethical appeal of adopting this intellectual persona, in this paper we are concerned with the style of historiography that it requires. In particular, we argue that the imperative to discover and foster the beginnings of social change leads to a version of philosophical history that will likely produce systematic anachronism. This is not uncommon in the discipline of International Relations, but in the case of Cox it stands in tension with some of his avowed intellectual sources, especially the work of Giambattista Vico, and with the aim of providing critical historical perspective on the present. We argue that Vico stands as an example of an alternative historical-empirical line of research that would better serve Coxian ambitions.  相似文献

Despite the extensive literature suggesting that culture plays a key role in lean implementations, no previous review has focused on the topic. This study is a systematic review of the literature that synthesises over two decades of publications according to the levels of national culture (NC) and organisational culture (OC) and maps which cultural dimensions foster or hinder lean implementation. In terms of NC, this study shows that Japanese cultural traits might hinder lean, such as masculinity and power distance, hence avoiding the over simplification that lean is a country-specific management approach. In terms of OC, the literature review unveils a lack of consensus and underlines two paradoxes, namely the co-existence of both process and result-focused orientations and both normative and pragmatic approaches. This review ultimately offers a relevant agenda for lean research as well as a guide for managers who face the challenge of implementing and sustaining lean in their organisations.  相似文献

Research suggests the relationship between pleasure and condom use during penile–vaginal intercourse (PVI) is associated with relationship status. This online study examined pleasure ratings and condom use at last PVI, stratifying by partner type, among a national sample of Canadian university students. Participants were 715 undergraduates (60.7% women, 39.3% men) who reported on their most recent sexual experience. Condom use decreased with level of relationship commitment, whereas ratings of pleasure increased. Overall, participants were more likely to rate their most recent PVI as Very pleasurable when condoms were not used compared to when condoms were used. However, when stratified by partner type, these differences largely disappeared. For women, with one exception, there were no differences in pleasure between PVI with and without condoms across most partner-type categories. Women in committed dating relationships were more likely to report their last PVI as very pleasurable if condoms were not used than women in these same relationships who had used condoms. Across relationship categories, men who did and did not use condoms did not differ in terms of their pleasure ratings. The results of this study suggest relationship context should be taken into account when assessing condom use experiences.  相似文献

An ecological evolutionary viewpoint offers new perspectives on contemporary demographic problems in general and on population–environment issues in particular. In turn, rich and detailed human demographic data can help solve problems of interest in evolutionary theory. Such data have been analyzed in greatest detail in studies of traditional and historical societies. Evolutionary approaches using historical data go beyond small‐sample anthropological studies to the application of the evolutionary approach to large datasets, and illuminate important similarities between small‐scale traditional societies and large modern populations living in evolutionarily novel environments. This article provides a concise update of the breadth of questions and hypotheses of likely interest to demographers and others that evolutionary theorists address using a variety of traditional and historical datasets. It suggests opportunities for additional collaborative work between evolutionary theorists and historical demographers and highlights topics relevant to modern demography.  相似文献

Abstract Recent initiatives from state and federal government agencies have helped foster the formation of community‐based watershed organizations. Although there is a great deal of enthusiasm about the potential of these organizations to enhance water quality, relatively little attention has been paid to the impacts these organizations may have on the well‐being of rural communities more generally. Assessments of effectiveness have typically focused on specific activities and accomplishments, rather than a broader range of community‐based effects. In short, we ask whether community‐based environmental management improves community as well as environment. Our research utilized a mixed‐methods design, including a statewide mail survey of all Pennsylvania watershed organizations, followed by in‐depth interviews with 28 rural watershed organizations. This sequential approach progressively explored in more detail definitions of effectiveness, including the building of rural capacity. We find watershed organizations are potentially effective mechanisms for building local leadership, enhancing the skills of rural residents, and making valuable connections with other communities, facing similar water‐resource and rural‐development issues. However, the range of issues with which local watershed organizations engage and the methods they currently utilize may eventually limit their usefulness.  相似文献

Social background has historically been recognized as a major factor influencing family behavior, though recent work has largely emphasized racial/ethnic influences. Here we use 1994 – 1995 and 2001 – 2002 Add Health data to examine the cohabitation, first marriage, and first birth experience of young women. In a multistate life table context, hypothetical cohorts specified in terms of race and mother’s education are followed, from age 11 to age 24, as they move through 6 family‐related statuses. The results indicate that, for both Black and White women, a higher level of maternal education is generally associated with less cohabitation, less marriage, fewer first births, and a higher percentage of women who experience none of those transitions before age 24. Racial and social background differences are conceptually and empirically distinct. Because mother’s education is associated with substantially different trajectories of early family behavior for both Blacks and Whites, we argue that social background merits increased attention in research on contemporary American family patterns.  相似文献
