This paper reports the results of interdisciplinary research extending the work of Mather and Peasnell (1991) reported in an earlier issue of this journal. Mather and Peasnell conducted an empirical analysis of the economic circumstances surrounding decisions to capitalize brands. This study investigates the managerial implications of periodically assessing and capitalizing the value of brands. Exploratory interviews were conducted with the key players in brand valuation activity, namely marketing and finance officials in brand-valuing companies and two senior personnel in the leading international brand-valuing agency. The recent inception of brand valuation in the accounts of several strong branded British companies provides an excellent research opportunity to explore a relatively novel managerial activity and its internal implications. These implications are reviewed under the headings: planning and control, the accounting/marketing interface, authorization of brand-related expenditure and brand-related decision making. An important finding of the study is that, while the original impetus for brand valuation came from balance sheet considerations, other unforseen managerial advantages are now widely perceived to accrue from brand valuation. The majority of current brand valuation activity appears to be driven more by management information needs, which are served by the evaluation phase of the exercise, than by a desire to capitalize brands in the published statements.  相似文献

The need for multilevel, comprehensive health promotion programmeshas become widely accepted, as has the importance of communityapproaches. However, many health promotion programmes focuson change at the individual level, no doubt partly due to thedifficulty of implementing all-inclusive health promotion. Thispaper discusses two strategies for guiding multilevel projects:multiple methods for community assessment and charting projectactivities by level of change (a possibility framework). Thesestrategies help ensure a multilevel focus and provide valuableinformation that can assist with the implementation of multilevelhealth promotion research projects in specific community contexts.Our primary purpose, therefore, is not to focus on theory orresearch findings. Rather, our goal is to make visible two strategiesthat have been helpful in one health promotion research projectin Victoria, British Columbia, Canada.  相似文献

A nationally representative sample of respondents estimated their fatality risks from four types of natural disasters, and indicated whether they favored governmental disaster relief. For all hazards, including auto accident risks, most respondents assessed their risks as being below average, with one-third assessing them as average. Individuals from high-risk states, or with experience with disasters, estimate risks higher, though by less than reasonable calculations require. Four-fifths of our respondents favor government relief for disaster victims, but only one-third do for victims in high-risk areas. Individuals who perceive themselves at higher risk are more supportive of government assistance.  相似文献

Employer use of employee drugscreening procedures is widespread in the U.S. A state-by-state analysis of statutory law applicable to the drug testing issue is combined with state and industry data to isolate how drug testing laws affect workplace injury rates. Based on our data, injury rates are not statistically related to the state’s legal environment.  相似文献

Abstract Over the 1980–1990 period, employment in producer services industries in the nonmetropolitan United States increased substantially. This growth resulted in the development of nonmetropolitan growth nodes in producer services industries. A growth node refers to a nonmetropolitan area that contains a greater than average concentration of employment in a particular industry sector relative to other nonmetropolitan areas. Moreover, this industry concentration not only increases over time, but also represents an important source of employment growth within the area. With nonmetropolitan counties as the spatial unit of analysis, 317 growth nodes in producer services industries are identified for the 1980–1990 period. Access to workers with clerical and administrative support skills, access to highly educated workers, higher earnings per employed worker, access to recreational amenities, and proximity to metropolitan areas were associated with the development of nonmetropolitan growth nodes in producer services industries during this period.  相似文献

Summary.  The system for monitoring suicides in Hong Kong has considerable delays in reporting as the cause of death needs to be determined by a coroner's investigation. However, timely estimates of suicide rates are desirable to assist in the formulation of public health policies. This motivated us to develop a non-parametric procedure to estimate the intensity function of a Poisson process in the presence of reporting delays. We give closed form estimators of the Poisson intensity and the delay distribution, conduct simulation studies to evaluate the method proposed and derive their asymptotic properties. The method proposed is applied to estimate the intensity of suicide in Hong Kong.  相似文献
