This study replicates, refines, cross-validates and simplifies a scheme of operationalization and measurement of environmental dimensions proposed by Dess and Beard (1984). Employing a sample of 60 industries and data over a 16-year period, this study found considerable support for the viability of the three dimensions of munificence, dynamism and complexity. The data intensive and computationally complex operationalization scheme was simplified using a discriminant analysis approach and the discriminant functions were cross-validated using an alternate data set.  相似文献

Abstract

Balanced repeated measurements designs (RMDs) balance out the residual effects. Williams Latin square designs work as minimal combinatorial balanced as well as variance balanced for RMDs for p (period sizes) = v (number of treatments). If minimal balanced RMDs cannot be constructed for the situations where p must be less than v then weakly balanced RMDs should be preferred. In this article, some generators are developed to generate circular weakly balanced RMDs in periods of two different sizes. To obtain the proposed designs, some construction procedures are also described for some of the cases where we could not develop generators.  相似文献

Repeated measurements designs (RMD) are widely used in medicine, pharmacology, animal sciences, and psychology. If there is a restriction on the total number of treatments, some experimental units can receive on the total length of time while some experimental units can remain in the trial, then RMD in periods of unequal sizes should be used. In this article, some infinite series are developed to generate the minimal circular strongly balanced RMD in periods of three different sizes p1, p2, and p3, where 2 ≤ p3 < p2 ≤ 10.  相似文献

Abstract

This article is based on the qualitative findings of a 4-year study of 150 adult African American men who are non-custodial fathers. Using social constructionist and ecological frameworks, issues of individual, personality and family development are explored and implications for micro and macro social work practice are discussed.  相似文献

ABSTRACT

The March 15th terrorist attack started a national dialogue about prejudice in New Zealand. Previous research has investigated attitudes towards Muslims in comparison to ethnic minorities. However, presently, there are no nationally representative studies in New Zealand systematically comparing attitudes to Muslims with attitudes to other religious groups. Here, we present evidence from the New Zealand edition of the International Social Survey Programme module on religion, a national postal survey (N?=?1335) collected between September 2018 and February 2019. We assess perceived threat and negativity towards Christians, Muslims, Hindus, Buddhists, Jews, and Atheists. We find substantially greater perceived threat and negativity towards Muslims compared with other groups. In particular, older people, New Zealand Europeans, men, and those with more right-wing attitudes report greater threat and negativity towards Muslims. In line with previous studies, higher religious identification and higher education predict greater acceptance. Taken collectively, these results reveal that the Muslim Acceptance Gap in this country is substantial, and greater challenges for acceptance are evident among lower-educated, right-wing, older, secular, and male populations. The magnitude of this gap reveals a substantial challenge to the future of New Zealand where religious and secular people can live without evoking prejudice.  相似文献

This paper critically reviews two major models of incrementalism and four explanations for non-incremental policy making. Key differences between these models are identified and a model of policy formulation which integrates incremental and non-incremental models is developed. Theoretical and methodological implications of this model are identified and research propositions are developed.  相似文献

This study used social cognitive career theory (Lent, Brown, & Hackett, 1994 ) to investigate the career development of 9th‐grade students living in 2 rural communities with large numbers of Latino immigrants. Participants (55.3% Latino) responded to measures of vocational skills self‐efficacy, career decision outcome expectations, career aspirations, and barriers to postsecondary education. Contrary to previous findings, results indicated that Latino students in these communities reported higher self‐efficacy beliefs than did White students. Latino students also reported higher perceived barriers, but this did not seem to relate to their career aspirations. Results suggest that school and career counselors should focus on programming that attends to Latino students' self‐efficacy and outcome expectations, as well as efficacy for overcoming barriers. Doing so could prove useful for increasing career achievement among rural Latino youth.  相似文献

Project HOPE comprises a health science career pipeline program based in social cognitive career theory. The program aims to promote health science career exploration for rural and Latino middle school students while simultaneously emphasizing the importance of achieving in math and science subjects. The authors conducted 2 studies to evaluate Project HOPE using baseline and follow‐up evaluation data. Results of Study 1 indicated that Project HOPE was associated with increases in math/science self‐efficacy for both Latino (n = 42) and European American (n = 31) students. Results of Study 2 indicated that Project HOPE was associated with higher health science career self‐efficacy beliefs for European American students (n = 22) and higher health science career interests for Latino students (n = 28). These results suggest that domain‐specific career interventions for middle school students that focus on jobs tied to the local economy may be a useful way to engage students in career exploration.  相似文献

An examination of social cognitive career theory (SCCT; R. W. Lent, S. D. Brown, & G. Hackett, 1994, 2000) factors contributing to the college expectations of high school students (N = 87) in rural Appalachia was conducted. Hierarchical multiple regression analyses revealed support for the role of SCCT variables in predicting expectations to attend college. Specifically, the SCCT variables of perceptions of parental support and self‐efficacy beliefs independently predicted Appalachian youth's expectations to attend college. Results are discussed in relation to SCCT, and implications for counseling and future research are presented.  相似文献

This paper presents selected aspects of experience with the intra-uterine contraceptive device (IUD) in rural West Pakistan. There were 1,162 IUD cases analyzed with respect to retention or non-retention. Retention rates were estimated, using life table methods, to be between 55 and 75 percent at one year; the smaller figure was obtained when theIUD was considered to be in situ only until the last examination, when it was observed to be in place. The latter or larger figure was obtained when the IUD was considered to be in situ unless known to be out.The extent of follow-up greatly affects estimates of the length of time the IUD remains in situ. Retention also varies with the type of I UD employed; exclusive use of Loop 3, which has the best retention record of those used,may be expected to yield higher retention rates by as much as 5 to 10 percent for one year. A number of other factors were examined that might explain non-retention. The objective variables that were examined in this experience, such as age, previous contraception, and husband's illiteracy, were on the whole rather poor predictors of IUD retention. Expulsion and other medical complications appear to account for most discontinuance of use of the IUD.  相似文献
