CEOs affect corporate outcomes along various dimensions, including the emphasis placed on long-term strategic planning. This study assesses the impact of CEOs’functional and industry specializations on R&D and capital spending in four manufacturing industries. We found only limited support for our position that CEOs with more professional-type careers are less willing than other CEOs to have their firms make long-term investments. “A critical theme of… the modem industrial enterprise is that creating and maintaining such capabilities is a continuing, long-term process–a process that requires sound, long-term perspectives from the decision makers responsible for the health and growth of their enterprise.” (Chandler 1991, p. 627)  相似文献

We present a hypothetical case study using the Years of Potential Life Lost (YPLL) metric to compare cancer risks incurred by residents living near a Superfund site to occupational fatality risks incurred by workers employed in that site's remediation. Since cancer occurs late in life, and because we assume its mortality rate is 60%, each case results in 8.8 YPLL. Each occupational fatality, which typically occurs earlier in life, results in 38.1 YPLL. In our case study, the residential population of 5000 incurred 1.3 YPLL, compared to 5.7 YPLL incurred by the 500 workers. Several uncertain assumptions may influence our calculations; moreover, occupational risks may be viewed as more "voluntary" than risks incurred by residents. However, because the magnitude of the YPLL incurred by workers and residents may be comparable, risk managers should consider occupational risks when evaluating remedial alternatives.  相似文献

Depression is one of the most commonly diagnosed psychiatric disorders among school-aged youth, with high prevalence and far-reaching consequences. However, even though there are two evidence-based practices for treating adolescent depression (Cognitive-Behavioral Therapy and Interpersonal Therapy), most adolescents referred for treatment are unlikely to receive either. In part, this is due to the difficulty of transporting an evidence-based practice from laboratory to real-world setting, and determining how to transport an empirically validated treatment has thus become a focus of concern for social work researchers and practitioners. A host of client, clinician, setting, and treatment delivery variables can influence portability. Taking all these factors into consideration is a daunting task—but less daunting if done at the onset, during the initial process of efficacy research, rather than afterward as a separate stage. The thesis of this paper is that the only solution to the problem of portability is a combined, rather than sequential, approach to treatment development in which effectiveness and application concerns are included in the original research design. A review of suggested approaches, as well as discussion of factors that contribute to variance in outcome, is followed by recommendations for future research.  相似文献

Two studies of working families are combined to demonstrate a strategy for producing reliable estimates from the combination of self-reported (large N) and observational (small N) data. Both studies examine where and how dual-career families spend time at home. The 500 Family Study is sociological and uses self-reported time diary data from a national sample; the CELF study is anthropological and uses observational scan sampling data from a regional sample of 32 families. The data are combined as if they constitute one sample, and an analytic solution for establishing the reliability of the resulting composite estimates of time use is provided. Merging the data sets provides validation for each study, neither of which is without potential methodological weaknesses. The advantages of combining data from the independent data collection methods are discussed, and selected substantive findings on families' activities are highlighted, illustrating similarities and differences between findings in the independent and combined data sets. Results show that working families spend significant time in a small spectrum of home spaces, particularly kitchens and living rooms, with leisure activities prevailing, but mothers, fathers, and children differ in where and how they spend their time. Overall, a template for merging data from different disciplines and methods is provided.  相似文献

This exploratory paper asks: ‘how do organizational food and drink rituals shape, reflect or create organizational culture?’ Adopting an embodied approach based on Merleau-Ponty's [1945. Phenomenology of Perception. Translated by C. Smith, 2003. London: Penguin. New York: Routledge] phenomenological work, this paper explores the significance of food-based rituals. Data were collected from different organizations using mixed methods and an embodied, reflexive approach – which is relatively novel in organizational research. Embodied experiences are potent, and this paper proposes that workplace food and drink rituals can powerfully influence perceptions of organizational culture. The unique contribution is in showing how embodied organizational rituals create and sustain organizational culture by using the pre-reflective moment of food ingestion to shape cognitive reconstructions of organizational culture. However, food rituals can be controlled and shaped by the organization to specifically influence employee perceptions of organizational culture. Control of food rituals can be perceived as a deliberate effort to create a constructive culture and encourage reciprocity through employee loyalty and effort.  相似文献

Social-emotional intelligence (SEI) has been linked with a number of health behaviors in adolescent populations. However, little is known about the influence of SEI on sexual behavior. This study examined associations between three indicators of SEI (intrapersonal skills, interpersonal skills, stress management skills) and adolescent girls’ sexual risk behaviors. Data come from a cross-sectional sample of sexually active adolescent girls (ages 13 to 17 years) at high risk for pregnancy (N = 253), recruited from health care clinics in a Midwest metropolitan area during 2007 and 2008. Results of multivariable regression models controlling for participants’ age and race/ethnicity indicated that each aspect of SEI was related to distinct sexual risk behaviors. Specifically, girls with greater intrapersonal skills had significantly fewer male sex partners in the past six months (b = ?0.16). Participants with greater interpersonal skills reported earlier communication with their sexual partner about sexual risk (b = 0.14), and those with a better ability to manage stress reported more consistent condom use (b = 0.31). Study findings suggest that SEI may provide a protective buffer against sexual risk behaviors. Building adolescent girls’ social and emotional skills may be an effective strategy for reducing their risk for early pregnancy and sexually transmitted infections.  相似文献

Aboriginal (meaning original peoples) North American mental health is acknowledged to be in a more precarious state than that of the dominant cultures. Disability arises from the conditions of poverty, homelessness, and lack of resources that are compounded for North American aboriginal people by the historical trauma of conquest, being placed on reservations, residential schools, and continued discrimination. We present culturally sensitive and syntonic intervention programs that can reduce the impact of Aboriginal mental disabilities and discuss the commonality among these programs of celebrating culture, language, and tradition.  相似文献

Among non-clinical populations, perceived social support is an important factor in health maintenance and well-being. Among measures that purport to assess perceived social support, the Medical Outcomes Study Social Support Survey (MOS-SSS) is based on a strong conceptual framework and has been subjected to a rigorous psychometric evaluation. Since no studies have investigated its psychometric properties with a young, non-clinical population, the purpose of this study is to investigate the psychometric properties (construct validity, internal consistency, and test–retest reliability) of an Italian version of the MOS-SSS with a non-clinical population sample. A convenience sample of 485 undergraduate students (73.0 % female; mean age = 21.81 ± 1.52) has been recruited. With regards to scale dimensionality, the best fit measurement model found support for the four subscales proposed by the original version: emotional and informational support, tangible support, positive social interactions, and affectionate support (χ 2/df = 4.49; CFI = .92; TLI = .91; RMSEA = .08). MOS-SSS subscales showed good internal consistency (Cronbach’s alpha for the subscales ranged from .848 to .939). Significant correlations were found with measures of psychological well-being (Ryff’s Scales of Psychological Well-Being) and depression (Beck-Depression Inventory-II). Test–retest stability was tested by examining a subsample (N = 225) over a 10-week period (correlation coefficients for the subscales ranged from .502 to .579). The findings suggest that MOS-SSS presents good psychometric characteristics with a young general population sample. Therefore, the MOS-SSS seems to be a psychometrically sound measure for the evaluation of perceived social support among young non-clinical populations.  相似文献
