Though built with increasingly precise microfoundations, modern optimizing sticky price models have displayed a chronic inability to generate large and persistent real responses to monetary shocks, as recently stressed by Chari, Kehoe, and McGrattan (2000). We trace this lack of persistence to a standard view of the cyclical behavior of real marginal cost built into current sticky price macro models. Using a fully articulated general equilibrium model, we develop an alternative perspective on real marginal cost that leads to substantial persistence. Based on an important role for materials input, variable capacity utilization, and labor adjustment on the extensive margin, this alternative view also makes the sticky price model display volatility and comovement of factor inputs and factor prices more closely in line with conventional wisdom about business cycles and various empirical studies of the dynamic effects of monetary shocks.

The notion of a ‘strategic issues’ is rather pervasive in the field of planning in both conceptual [5, 19] and practical contexts. For instance, sometime ago the Wall Street Journal [41] reported that at least 50 large firms have created positions of ‘issues management director’; a dramatic increase in the number of such positions. ‘True’ strategic issues have a readily apparent importance to any organization; yet the process of identifying such issues and of integrating them into strategic planning and management is not well developed. Most treatments of strategic issues deal only with specific segments of the overall process through which relevant issues may be initially identified and finally translated into appropriate strategy [e.g. 5, 17]. This paper demonstrates that it is practical to develop a comprehensive process of ‘strategic issue management’ (SIM) that will facilitate the systematic identification, assessment and analysis of such issues. Such a process can ensure that issue-related factors are fully integrated into the formulation and implementation of strategy and plans. As such, SIM is a process whereby strategic issues may become an integral element of strategic management.  相似文献

By adapting to the changing health care environment, legislative reforms, and consumer needs, work rehabilitation programs have experienced a metamorphosis. This study surveyed occupational therapists currently employed in work programs to ascertain a current demographic profile of work rehabilitation programs. Respondents indicated the delivery of services in the areas of prevention, assessment and rehabilitation. The majority of work rehabilitation programs in this study provide services in the form of ergonomics, education and training, and job analyses at the worksite. The area of work injury prevention services is forecasted for increased growth among work rehabilitation programs.  相似文献

Correspondence to: Professor Colin Pritchard, Department of Mental Health, School of Medicine, Southampton University, Royal South Hants Hospital, Southampton SO14 0YG, UK. E-mail: cp1{at}soton.ac.uk Summary The study compares Mental-Disorder-Related (MDR) suicide rateswith Child-Sex-Abuse-Related (CSAR) suicide of ‘Victims’and ‘Perpetrators’ of child sex abuse, based uponan examination of all Coroners’ inquest files over a six-yearperiod (n = 1,017). Census data, psychiatric case register andpolice records were used to calculate the potential MDR andCSAR populations. There were five main findings: (i) male andfemale CSAR victim suicide rates were 2.2. and 2.5 times theGeneral Population Suicide Rate (GPSR), respectively; (ii) everyfemale, and 80 per cent of male CSAR victim suicides, also hada mental disorder but none of the CSAR perpetrator suicides;(iii) male and female MDR suicide rates were 5 and 6 times theCSAR Victim rates; (iv) the sex abuser perpetrators’ suiciderate was more than 3 times the male MDR rate; (v) the intra-and extra-familial perpetrator suicide rates, were 25 and 78times the GPSR, respectively. Possible explanations for thesesurprising results are briefly discussed. They confirm the overrepresentationof people with mental disorder amongst suicides, and identifyan overrepresentation of CSAR suicides, particularly perpetrators.The results have implications for suicide prevention programmes,whilst highlighting the importance of the child protection-psychiatricinterface, and indicates the futility of simple explanationsin an area of practical and moral complexity.  相似文献

Musculoskeletal disorders (MSDs) have been recognized as a serious hazard to the health and safety of sonographers. Recommendations have been made on ways to reduce and prevent the frequency and severity of these disorders. The purpose of this study was to ascertain the impact ergonomics has had on the prevalence of MSDs among cardiac sonographers. Three hundred randomly selected Registered Diagnostic Cardiac Sonographers were surveyed. Eighty-one respondents completed the survey. The majority of the sample population was female with an average age of 40 and job tenure between 6-15 years. Ninety percent of respondents reported musculoskeletal pain/discomfort while scanning. Seventy-three percent of respondents perceived a need for ergonomic interventions. The majority of respondents were aware of previously recommended ergonomic interventions and had implemented what was feasible. Still, the experience of pain and discomfort, and incidence of MSDs remains exceptionally high for this occupation. It appears that recommended ergonomic interventions have not had a significant impact on improving the health and safety of cardiac sonographers.  相似文献

A new Rank Order Cluster Algorithm is discussed which provides a simple, effective and efficient analytical technique for the formation of machine-component groupings. The method is specifically developed for computer application although it is possible for it to be used for manual computation, if required, particularly for smaller problems.  相似文献

The problem of keeping abreast of relevant competitive developments for strategic purposes is common to many organizations. In this article the authors describe a system which they have developed and which is currently in operation which they believe can prove beneficial in meeting this need. They believe that their system provides competitive data in a useful form. Also it ensures that information, and not data, are processed and provided for planners and managers to support their decision-making.  相似文献

In this article, we investigate the potential usefulness of the three-parameter transmuted generalized exponential distribution for analyzing lifetime data. We compare it with various generalizations of the two-parameter exponential distribution using maximum likelihood estimation. Some mathematical properties of the new extended model including expressions for the quantile and moments are investigated. We propose a location-scale regression model, based on the log-transmuted generalized exponential distribution. Two applications with real data are given to illustrate the proposed family of lifetime distributions.  相似文献

The 1995 wave of the Add Health study is used to investigate the relative influence of parent gender and residence on patterns of parental involvement with adolescents. Adolescent reports (N =17,330) of shared activities, shared communication, and relationship quality with both biological parents are utilized. A multidimensional scaling analysis reveals that parent gender explains most of the variance in parent‐adolescent involvement, with residential status playing a secondary yet a fundamental role in accounting for these patterns. Resident mothers who do not live with adolescents’ biological fathers engage in the broadest range of activities with their children. Unpartnered resident fathers display patterns of parenting that are as similar to mothers as they are to other fathers.  相似文献
