In this paper some of the techniques available for strategic planning are reviewed. Four techniques are presented, the experience curve, the growth-share matrix, the directional policy matrix and the PIMS program. The results of a survey into the use of these techniques in the United Kingdom are also presented. 相似文献

Reducing the Risk of Injury from Table Saw Use: The Potential Benefits and Costs of Automatic Protection 下载免费PDF全文
The use of table saws in the United States is associated with approximately 28,000 emergency department (ED) visits and 2,000 cases of finger amputation per year. This article provides a quantitative estimate of the economic benefits of automatic protection systems that could be designed into new table saw products. Benefits are defined as reduced health‐care costs, enhanced production at work, and diminished pain and suffering. The present value of the benefits of automatic protection over the life of the table saw are interpreted as the switch‐point cost value, the maximum investment in automatic protection that can be justified by benefit‐cost comparison. Using two alternative methods for monetizing pain and suffering, the study finds switch‐point cost values of $753 and $561 per saw. These point estimates are sensitive to the values of inputs, especially the average cost of injury. The various switch‐point cost values are substantially higher than rough estimates of the incremental cost of automatic protection systems. Uncertainties and future research needs are discussed. 相似文献

The EPA Health Risk Assessment of Methylcyclopentadienyl Manganese Tricarbonyl (MMT) 总被引:1,自引:0,他引:1
This paper describes the U.S. Environmental Protection Agency's assessment of potential health risks associated with the possible widespread use of a manganese (Mn)-based fuel additive, methylcyclopentadienyl manganese tricarbonyl (MMT). This assessment was significant in several respects and may be instructive in identifying certain methodological issues of general relevance to risk assessment. A major feature of the inhalation health risk assessment was the derivation of Mn inhalation reference concentration (RfC) estimates using various statistical approaches, including benchmark dose and Bayesian analyses. The exposure assessment component used data from the Particle Total Exposure Assessment Methodology (PTEAM) study and other sources to estimate personal exposure levels of particulate Mn attributable to the permitted use of MMT in leaded gasoline in Riverside, CA, at the time of the PTEAM study; on this basis it was then possible to predict a distribution of possible future exposure levels associated with the use of MMT in all unleaded gasoline. Qualitative as well as quantitative aspects of the risk characterization are summarized, along with inherent uncertainties due to data limitations. 相似文献

Discourse analysis can be used to understand and interpret culturally and socially produced meanings regarding work and to outline how specific rules and conventions can configure meaning production of work in context. The implications of some core concepts in discourse analysis pertinent to career counseling are explored, including discourse, deconstruction, power/knowledge, psy‐complex, ideology, and identity. Such an exploration has the potential to initiate a process of critical self‐reflection in career counseling and development so as to enhance ethical, fair, and inclusive practices in the field. 相似文献

This paper shows that the semiparametric efficiency bound for a parameter identified by an unconditional moment restriction with data missing at random (MAR) coincides with that of a particular augmented moment condition problem. The augmented system consists of the inverse probability weighted (IPW) original moment restriction and an additional conditional moment restriction which exhausts all other implications of the MAR assumption. The paper also investigates the value of additional semiparametric restrictions on the conditional expectation function (CEF) of the original moment function given always observed covariates. In the program evaluation context, for example, such restrictions are implied by semiparametric models for the potential outcome CEFs given baseline covariates. The efficiency bound associated with this model is shown to also coincide with that of a particular moment condition problem. Some implications of these results for estimation are briefly discussed. 相似文献

This article uses Probation Department files to reconstruct the lives of five ordinary residents of Harlem. It highlights what that black metropolis offered those outside the political and cultural elite, who have dominated historical scholarship, showing how ordinary blacks negotiated the challenges of life in northern neighborhoods, and drew on institutions and organizations, to establish and sustain new lives. We offer the kind of individualized perspective on everyday life that other scholars have provided for high culture, but which does not exist for other realms of existence in Harlem, even in early twentieth century sociological studies of black life. Where scholars seeking to distinguish the neighborhood from a slum have pointed to the prevailing pride and self-confidence of its residents, this article directs attention to more immediate, concrete supports that sustained and enriched life in Harlem. Relationships with spouses, children, siblings and cousins sustained individuals faced with the social reality of living in overcrowded, deteriorating, disease infested housing, subject to the racism of white police, politicians and employers; so too did friendships made in nightclubs, speakeasies, dances and movie theatres, and membership of churches, fraternal organizations, social clubs, and sports clubs and teams. 相似文献

This paper proposes a new method for identifying social interactions using conditional variance restrictions. The method provides a consistent estimate of the social multiplier when social interactions take the “linear‐in‐means” form (Manski (1993)). When social interactions are not of the linear‐in‐means form, the estimator, under certain conditions, continues to form the basis of a consistent test of the no social interactions null with correct large sample size. The methods are illustrated using data from the Tennessee class size reduction experiment Project STAR. The application suggests that differences in peer group quality were an important source of individual‐level variation in the academic achievement of Project STAR kindergarten students. 相似文献

This article explores contemporary uses of museum co-production for public policy through a sustained theoretical engagement with Tony Bennett's work on museums as an ‘object of government’. The specific focus is a theoretical discussion of the ‘logic of culture’ as it relates to new UK policy uses of participants' ‘experience’ as the desired site of authenticity at the very same time as the process of expressing this authenticity is located as a site for reform. It is argued that Bennett mobilizes two techniques of scale (fixing the analytic lens of governmentality and drawing on a strong scalar correspondence of power) in order to secure a relatively disciplinary reading of governmentality and to foreclose the resistant possibilities of cultural politics. Drawing on the differences between practices associated in UK museums with ‘access’ (which works through the dis-intensification of the difference between the museum and everyday life) and with ‘social impact’ (which requires a re-intensification of this difference in order to increase the visibility of effect), this article concludes by countering Bennett's more disciplinary uses of Foucault with the Foucault of ‘The Subject and Power’. It is argued that the ‘logic of culture’ can be calibrated to varying intensities in considering the coming-into-relationship between the museums and those-to-be-involved. It is specifically argued – following Foucault's spatializaton of ‘thought’ as distance (limit-attitude) and ‘counter-conduct’ as proximity – that the ‘logic of culture’ might be actively re-calibrated to use the spatialized dynamic of distance and proximity to create spaces which might allow the museum and its associated policy – not just those involved – to be affected by the co-production encounter. 相似文献
