This article discusses the results of a recent study of marketing planning in U.K. manufacturing companies. A sample survey revealed some strengths in marketing planning, but also revealed many weaknesses. For example, only a small proportion of companies prepare a comprehensive marketing plan. These identified weaknesses suggest that, in many situations, marketing planning has failed and the author suggests where it has failed. After discussing the results in detail, the author summarizes the identified strengths and weaknesses and suggests several implications for managers who are responsible for marketing planning.  相似文献

Although there is an extensive and varied literature on the nature and consequences of unemployment very little has been written about the experiences of jobless women. This is unfortunate since there are good sociological reasons why the reactions to job loss among women may be different from those of men. Empirical data tend to support this expectation although more research is needed and called for. Sociological studies of unemployed women could contribute to the development of theories about wage-work, family life and domestic labour. Women's unemployment also has a broader significance in that it bears directly upon theories of social stratification and social order that are central to sociological study as a whole.  相似文献

A model is developed to use marital history data from the U.S. Current Population Survey and mortality statistics from the federal registration system to estimate color differences in (a) the risk of widowhood among women in the working ages and (b) the cumulative duration of widowhood. Color differentials in mortality among married males are thereby translated into person-years of dependent survivorship among women, in anticipation of our later estimating average and cumulative lifetime income losses for the survivors. Initial results of this model, dealing with the demographic aspects of survivorship, are presented.  相似文献

This paper describes an investigation of two statistics which compare two ordered sequences of objects by providing a measure of the discordance when the sequences are slotted together. Configurations having zero discordance are described. Plausible null models for data are postulated, and an account is given of a simulation study which investigated the distribution of the statistics when these models were used in the analysis of physical logging data from two wells.  相似文献

Studies have shown that exposure to discrimination increases the probability that African American adolescents will engage in delinquent behavior, especially acts of violence. The present study extended this research by examining the extent to which supportive parenting buffers a youth from these deleterious consequences of discrimination. Analyses based upon two waves of data from a sample of 332 African American adolescent males and their caretakers supported this hypothesis. Further the results indicated that there are two avenues whereby supportive parenting reduces the probability that discrimination will lead to violence. First, supportive parenting decreases the chances that discrimination will lead to anger and a hostile view of relationships. Second, supportive parenting lowers the risk that anger or a hostile view of relationships, when they develop, will result in violence.  相似文献

Abstract

The criteria for selecting a serials management system are often the same as those for selecting an integrated library system in toto. In the post-selection/production environment, the library–vendor relationship matures as a new operational framework is established. Serials management systems must become more efficient and make better use of electronic commerce, especially as a greater emphasis is placed on access to electronic journals (e-journals). Serials Review 2002; 28:93–101.  相似文献

Abstract

Collection development policies in small academic libraries may lack a formal policy statement about print periodical holdings retention. However, there is a need for a distinct policy about print periodicals holdings and their retention. Periodicals collections at academic libraries have been greatly affected by publishers’ decisions to discontinue print journal formats and move to online-only electronic versions. The move from one format to another produces challenges to the retention of an effective print periodicals collection. Given these continuous changes in publication format, it is necessary for academic libraries to rethink their print periodicals holdings retention. This article will present a literature review on and case study of periodicals collection management and explore strategies for developing holdings policies and guidelines for retention. It will argue that collection development policies ought to include a separate policy for the print periodicals collection and that unlike their reputation for being time-consuming and inflexible, periodical retention policies can improve flexibility and guide in decision making, helping to preserve core titles and acquire new titles that support academic programs and the work of the college community.  相似文献
