This paper explores the reasons for industries converging upon poor strategies. The phenomenon is likened to the periodic mass suicide of the lemmus lemmus (the Norwegian lemming). It gives historic examples of the phenomenon, and evidence of its occurring within a simulated business environment. A literature review shows how it can be explained using theories from economics, psychology and competitive analogies used in business. An inputs-process–outputs model provides a theoretical framework for Lemmus Lemmus strategies and is used to derive hypotheses.  相似文献

The large differences in youth smoking behavior across ethnic and racial groups are often overlooked in debates about prevention. This study examines how the determinants of the onset of smoking vary by race and ethnicity. Academic success is strongly associated with lower smoking rates among white youth, but this is not as true for Hispanics and African-Americans. Cultural assimilation may be an important determinant of smoking for Hispanics. Price increases do not appear to reduce smoking onset among white youth, but the results provide some support that higher prices will reduce smoking among Hispanic and African-American youth.  相似文献

Quality of Post-1965 Asian Immigrants   总被引:1,自引:1,他引:0  
The reliance on an overall average approach to the labor market quality of immigrants could generate misleading information and biased policy recommendations. Focusing on Asian immigrants, this article demonstrates that much insight into immigrant quality can be gained via a diversity approach. Using the 5% PUMS data of the 1990 U.S. census, this paper shows that a common perception that the quality of post-1965 immigrants is lower than natives and earlier immigrants is invalid for post-1965 Asian immigrants. Unlike their Latin American counterparts, post-1965 Asian immigrants are generally more educated and skilled than natives. The educational level of post-1965 Asian immigrants surpasses that of their pre-1965 counterparts, despite their disadvantage in occupational attainment due to their shorter time of adaptation. Diversity also characterizes educational and occupational attainment across major post-1965 Asian immigrant groups and within each Asian immigrant group before and after 1965. Gender does not alter the advantage of post-1965 Asian immigrants over natives and their pre-1965 parallels in education, but it does complicate their occupational status. Policy implications of the findings are considered.  相似文献

This field study provides variables that can be used by practitioners as action levers and by future researchers as the basis for theoretical development. Conclusions from relevant literature and findings from interviews with interdisciplinary research management identified forty variables that were viewed as important to interdisciplinary research project success. After adjusting the data for reliability attenuation, these variables were further analyzed to identify the best prediction equation. The findings suggested that project age or the longevity of the project and open discussion of disagreements were the best predictors of performance.  相似文献

The main argument of this article is that corporate planners have tended to concentrate on subjects such as control of business strategies, financial management and global economic assessment; they have paid too little attention to the ownership of corporate entities. Apart from the overwhelming economic and social arguments in favour of dispersed ownership, there is increasing evidence that companies which adopt a positive planning approach to the ownership of their business will derive wider benefits. Much more statistical and attitudinal evaluation is required; individual companies need to support the macro-work of academic research with detailed micro-studies at the company level. If these studies continue to support the basic argument, there are positive steps which each company will be able to take to support the cause of wider ownership.  相似文献

Despite widespread recognition of the usefulness of a biopsychosocial approach in social work, there are limited studies exploring how social workers can use this approach to support the health and wellbeing of carers of young people with first episode psychosis (FEP). Validated questionnaires and anthropometric measures were used to assess the physical health and wellbeing of 42 carers of young people with FEP. Carers had moderate levels of negative caregiving consequences, quality of life, and health status. More than half (52.4%) of carers were experiencing social isolation. Many carers were overweight (78.6%), had a high risk for type 2 diabetes (39.0%), and had hypertension (33.3%). Practical implications of a biopsychosocial approach to social work that supports both clients and their carers are discussed.  相似文献

The concepts of vulnerability and resilience help explain why natural hazards of similar type and magnitude can have disparate impacts on varying communities. Numerous frameworks have been developed to measure these concepts, but a clear and consistent method of comparing them is lacking. Here, we develop a data-driven approach for reconciling a popular class of frameworks known as vulnerability and resilience indices. In particular, we conduct an exploratory factor analysis on a comprehensive set of variables from established indices measuring community vulnerability and resilience at the U.S. county level. The resulting factor model suggests that 50 of the 130 analyzed variables effectively load onto five dimensions: wealth, poverty, agencies per capita, elderly populations, and non–English-speaking populations. Additionally, the factor structure establishes an objective and intuitive schema for relating the constituent elements of vulnerability and resilience indices, in turn affording researchers a flexible yet robust baseline for validating and expanding upon current approaches.  相似文献

Abstract

Previous research has established that social work practitioners are especially vulnerable to work-related psychological distress and burnout due to the high-stress nature of the profession, yet less research has focused on examining factors are associated with social worker retention. Emerging research on compassion satisfaction suggests that this factor could mitigate professional burnout, yet there is a gap in research focusing explicitly on examining compassion satisfaction among social workers. To address this gap in knowledge, this quantitative study collected survey data on practicing social workers who were alumni from a large southeastern university (n?=?120) to examine individual and organizational factors associated with compassion satisfaction. Multiple regression analyses revealed that higher levels of emotional intelligence, perceived work autonomy, and perceived work–life balance were associated with an increase in compassion satisfaction among experienced, licensed social work practitioners. Findings have implications for how social work employers can promote compassion satisfaction through cultivating emotional intelligence among practitioners, allowing social workers autonomy in decision making, and providing supportive work environments. Recommended directions for future research include longitudinal studies with large sample sizes that expound research on compassion satisfaction by examining the role of additional factors, such as client population, job role characteristics, and supervisor support.  相似文献

The Australian Bureau of Agricultural & Resource Economics (ABARE) has conducted the annual Australian Agricultural and Grazing Industries Survey, covering the broadacre sector, in a consistent format since 1978/79. In this period the incomes of farmers have fluctuated considerably. Interest has focused on temporal income variation because of its relationship to the inherent riskiness of farming. Part of these income fluctuations can be explained by changing commodity prices and by highly variable climatic conditions. This paper outlines a method of measuring the magnitude of this income variation and how it relates to other variables. Due to rotation within the sample of farms surveyed, data are limited for determining the income variability of any particular farm. This paper, using spatial locations of surveyed farms, shows how kernel smoothing techniques can be adapted to estimate the distribution of a farm's income. This analysis uses data collected from 1978/79 to 1991/92. Summary information from these distributions is cross-tabulated against several other variables. This shows that income variability is strongly related to the production mixture of farming businesses.  相似文献
