Two competing theories of firm performance have been proposed in the business strategy literature, the industry structure view and the resource-based view of the firm. Empirical studies have estimated the relative contribution of industry structure, corporate, and business unit effects to business unit performance. These studies, however, have been restricted to using only single-country data. Missing from this debate is an international dimension that includes the relative importance of country conditions as a determinant of firm performance. The objective of this article is to fill this void by adding country characteristics to the analysis. Using cross-country data of four large multinationals in a single industry, we estimate the relative importance of country characteristics in addition to industry structure, corporate characteristics, and subsidiary strategy as determinants of subsidiary performance by using multiple regression analysis. This analysis also will contribute to the discussion on environmental determinism versus strategic choice. Country and industry characteristics are mainly outside the control of management, whereas corporate characteristics and subsidiary strategy are under management's control. Results show that country characteristics are by far the most important determinant of subsidiary performance, followed by industry structure, subsidiary strategy, and corporate characteristics. Thus, country conditions are a very important determinant of firm performance that so far has been overlooked in previous studies. These results indicate that subsidiary performance is determined mainly by conditions outside the control of subsidiary management. In terms of competing theories, these results support the environmental determinism view more than the strategic choice view and the resource-based view of the firm more than the industry structure view. These results also have important implications for multinational corporations' selection of countries for entry and investment and for performance evaluation of subsidiary management.  相似文献

ABSTRACT

This analysis focuses on parent involvement in public schooling within the United States of America from the colonial period to present. The analysis is framed by four major forces that influence the kind and degree of parent involvement: the cultural beliefs of families; the social structure of families; economic influences; and political pressures within the nation. The contemporary institutional and legal structure of schools tends to disconnect teachers and families. A tension appears to exist between professionals, on the one hand, who espouse the concept that they alone are qualified to make complex decisions affecting the education of our nation's children, and parents, on the other hand, who believe that they should have a voice in their children's compensatory public education.  相似文献

Abstract

Objective: To identify college presidents’ support for tobacco-free campus policies (TFCP), perceived barriers and benefits to implementing such policies, and activities that might initiate policy adoption. Participants: Participants were 405 presidents (51% of 796 delivered surveys) from a national sample of eligible 4-year institutions in summer 2012. Methods: A 4-page, 24-item cross-sectional questionnaire was mailed to potential participants in 4 waves to maximize the response rate. Results: The vast majority of presidents support TFCP (84%) and believed they should play a key role in establishing TFCP (80%). A majority agreed advocacy by campus groups was necessary to establishing TFCP. Presidents with an existing policy were twice as likely to believe advocacy was necessary for policy establishment. Presidents most commonly selected creating policy drafts and designating a committee as important to initiating TFCP. Conclusion: Advocates would benefit from focusing on presidential involvement and solutions to personnel barriers in establishing TFCP.  相似文献

Little is known about people's willingness to engage in sex without protection from unwanted pregnancy. This study surveyed 1,497 women and men at 75 clinics and physician offices across California after their reproductive health care visits in late 2007 and early 2008. When asked if they would have sex without contraception, 30% said definitively that yes, they would have unprotected sex, and 20% indicated they would “sometimes” or “maybe” engage in unprotected sex. In multivariate models, compared to non-Latino White respondents, Latinos who responded to the survey in English were 52% more likely and African Americans were 75% more likely to report willingness to have unprotected intercourse. Wanting a child within the next three years was associated with increased willingness to have unprotected sex. Age, gender, parity, and relationship status were not significant in multivariate models. A considerable proportion of women and men may be willing to have unprotected sex, even with access to subsidized contraceptive services and even when recently counseled about birth control. The dominant behavioral models of contraceptive use need to acknowledge the widespread likelihood of occasional unprotected sex, even among people motivated to usually use contraceptives. Findings underscore the need to make contraceptive methods accessible, easy to use, and even pleasurable.  相似文献

Drawing on two recently completed ethnographic studies of young women in the West Midlands, this paper explores a series of issues about the application of feminist principles and practice to such research. One study analysed young women's friendships, mainly through participant observation in school, supplemented by participation at a youth club. The other explored the likely success of the former Conservative Government's ‘Health of the Nation's’ targets for aspects of young women's health, through extended attendance at two youth clubs, supplemented by ‘shadowing’ informants at school. Both studies also used interviews, diaries and other data sources. Driven by the researchers' desire to ‘give a voice’ to their informants, this paper reviews power relationships in the production of knowledge; issues about self-presentation; securing access to and winning the trust of the young women; and their resolution of some of the ethical dilemmas which confronted the researchers in the course of their fieldwork.  相似文献

This essay addresses a group of contemporary artworks which qualify as photography and painting at the same time. Because these works lack medium-specificity, several theorists refer to them as ‘pictures’. Analysis of this concept's etymological origin and of the art-historical context in which it appeared indeed reveals the concept's usefulness for discussing this particular group of artworks. However, merely defining them as ‘pictures’ would imply that important and interesting effects of the combination of photography and painting in these works are ignored, if not negated. This is why the authors coin the term ‘multi-mediating picture’ as a preferable concept in this context. As such it not only refers to the clearly discernible multiplication of media in these works, but it also indicates the layered and delayed perception that results from this multiplication. The authors demonstrate the suitability of their concept through a case-study of two photographs by Louise Lawler. Their analysis is geared to processes of appropriation involving both other media and images made by other artists.  相似文献

The welfare and migration regime of Sweden are undergoing substantial changes, as neo-liberal restructuring is rapidly increasing inequalities, and multicultural policies are in retreat as neo-assimilationist policies are growing. In 2014, the Sweden Democrats, a party conceptualised as culturally racist, was re-elected with 13% of the votes, with a presence in almost all municipalities. While scholarship on this and similar parties has expanded, the role that gender and gender equality has for the culturally racist articulation of their agenda remains unexplored. The experience of women organised in the Sweden Democrats is the focus of this article, the experience of these women engaged in local politics, working to include the Sweden Democrats' culturally racist agenda at the municipality level. The article draws upon in-depths interviews with women activists of the Sweden Democrats. Central to the article is an analysis of forms of inclusion and normalisation of the Sweden Democrats' worldviews but also of the forms of resistance towards their presence at the municipality level. Unlike mainstream research, which downplays the cultural racism of extreme right-wing parties, and rarely employ a gendered analysis, we see (cultural) racism and anti-feminism as central for their agenda.  相似文献

This study analyzes the effects of a conductor's power‐based leadership on orchestra quality. The structure of power‐based leadership and the hypotheses were tested with a sample of musicians from German orchestras. Confirmatory factor analyses verify four types of power‐based leadership of the conductor vis‐à‐vis the musicians: (1) expert/referent power, (2) informational power, (3) legitimate power through position, and (4) impersonal and personal reward and coercive power. The relative importance of the four forms of power‐based leadership on artistic quality was tested using structural equation modeling (SEM). The results supported the hypotheses that expert power and referent power have the strongest positive impact on artistic quality than all other forms of power‐based leadership under study. Contributions to theories of leadership and power, research methods, and practice are discussed.  相似文献

Summary.  In microarray experiments, accurate estimation of the gene variance is a key step in the identification of differentially expressed genes. Variance models go from the too stringent homoscedastic assumption to the overparameterized model assuming a specific variance for each gene. Between these two extremes there is some room for intermediate models. We propose a method that identifies clusters of genes with equal variance. We use a mixture model on the gene variance distribution. A test statistic for ranking and detecting differentially expressed genes is proposed. The method is illustrated with publicly available complementary deoxyribonucleic acid microarray experiments, an unpublished data set and further simulation studies.  相似文献
