In this paper, we attempt to reconcile contingency and institutional fit approaches concerning the organization-environment relationship. While prior scholarly research has examined both theories and compared their impacts on organizational fit and performance, we lay the groundwork for a meta-fit approach by investigating how contingency and institutional fit interact to influence firm performance. We test our theoretical framework using a dataset of 3,259 respondents from 1,904 companies regarding task environmental demands and institutional demands on organizational design across a broad range of industries and firm size classes. Our results show that contingency and institutional fit provide complementary and interdependent explanations of firm performance. Importantly, our findings indicate that for firms under conditions of “quasi-fit” rather than perfect contingency fit or optimal institutional fit, improvements in contingency and/or institutional fit will result in better performance. However, firms with high contingency fit are less vulnerable to deviation from institutional fit in the formation of firm performance, while firms with perfect institutional fit will slightly decrease their performance when they strive to achieve contingency fit.

Objective: to assess the separate contributions of marital status, living arrangements and the presence of children to subsequent admission to a care home.

Design and methods: a longitudinal study derived from the health card registration system and linked to the 2001 Census, comprising 28% of the Northern Ireland population was analysed using Cox regression to assess the likelihood of admission for 51,619 older people in the 6 years following the census. Cohort members’ age, sex, marital and health status and relationship to other household members were analysed.

Results: there were 2,138 care home admissions; a rate of 7.4 admissions per thousand person years. Those living alone had the highest likelihood of admission [hazard ratio (HR) compared with living with partner 1.66 (95% CI 1.48, 1.87)] but there was little difference between the never-married and the previously married. Living with children offered similar protection as living with a partner (HR 0.97; 95% CI 0.81, 1.16). The presence of children reduced admissions especially for married couples (HR 0.67 95% CI 0.54, 0.83; models adjusting for age, gender and health). Women were more likely to be admitted, though there were no gender differences for people living alone or those co-habiting with siblings.

Implications: presence of potential caregivers within the home, rather than those living elsewhere, is a major factor determining admission to care home. Further research should concentrate on the health and needs of these co-residents.

Institutional and economic development has recently returned to the forefront of economic analysis. The use of case studies (both historical and contemporary) has been important in this revival. Likewise, it has been argued recently by economic methodologists that historical context provides a kind of ‘‘laboratory’’ for the researcher interested in real world economic phenomena. Counterterrorism economics, in contrast with much of the rest of the literature on terrorism, has all too rarely drawn upon detailed contextual case studies. This article seeks to help remedy this problem. Archival evidence, including previously unpublished material on the DeLorean case, is an important feature of this article. The article examines how an inter-related strategy, which traded-off economic, security, and political considerations, operated during the Troubles. Economic repercussions of this strategy are discussed. An economic analysis of technical and organizational change within paramilitarism is also presented. A number of institutional lessons are discussed including: the optimal balance between carrot versus stick, centralization relative to decentralization, the economics of intelligence operations, and tit-for-tat violence. While existing economic models are arguably correct in identifying benefits from politico-economic decentralization, they downplay the element highlighted by institutional analysis.

This article considers how corporate behaviour in relation to climate change might be reconfigured and the role that indirect investors might play in this reconfiguring. The article suggests that the consequences of climate change are serious enough that indirect investors might be prevailed upon, using a model of behaviour suggested by the work of Hans Jonas, to pressure institutional investors into demanding changes in corporate policy towards climate change. Jonas' work represents a plea for the recognition and acceptance of responsibility in the face of nature's vulnerability and humanity's power over technology. The article suggests that this ethic can be operationalised in relation to corporate governance by building on the changes in the pattern of investment holdings that have taken place in large public companies in the preceding two decades or so. The idea is to appeal to individuals who may perceive themselves as currently being outsiders – or at least only distant stakeholders in relation to the corporation – to realise the responsibility vested in them as beneficiaries through their interest in pension funds, life assurance policies, annuities and other arm's-length financial arrangements with corporations. The hope is that these individuals may, through the influence of a model of responsibility, become active investors and beneficiaries interested in corporate practices that impact on climate change and, encourage others to do likewise.

This paper contributes to the literature on entrepreneurial leadership development. Leadership studies are characterized by an increasing emphasis given to an individual leader's social and organizational domain. Within the context of human capital and social capital theory, the paper reflects on the emergence of a social capital theory of leadership development. Using a retrospective, interpretivist research method, the authors present the experience of a cohort of business leaders on an executive development programme to uncover the everydayness of leadership development in practice. Specifically, they explore how entrepreneurial leadership develops as a social process and what the role of social capital is in this. The findings suggest that the enhancement of leaders’ human capital only occurred through their development of social capital. There is not, as extant literature suggests, a clear separation between leader development and leadership development. Further, the analysis implies that the social capital theory of leadership is limited in the context of the entrepreneurial small firm, and the authors propose that it should be expanded to incorporate institutional capital, that is, the formal structures and organizations which enhance the role of social capital and go beyond enriching the human capital stock of individual leaders

PURPOSE The appropriate selection of patients for early clinical trials presents a major challenge. Previous analyses focusing on this problem were limited by small size and by interpractice heterogeneity. This study aims to define prognostic factors to guide risk-benefit assessments by using a large patient database from multiple phase I trials. PATIENTS AND METHODS Data were collected from 2,182 eligible patients treated in phase I trials between 2005 and 2007 in 14 European institutions. We derived and validated independent prognostic factors for 90-day mortality by using multivariate logistic regression analysis. Results The 90-day mortality was 16.5% with a drug-related death rate of 0.4%. Trial discontinuation within 3 weeks occurred in 14% of patients primarily because of disease progression. Eight different prognostic variables for 90-day mortality were validated: performance status (PS), albumin, lactate dehydrogenase, alkaline phosphatase, number of metastatic sites, clinical tumor growth rate, lymphocytes, and WBC. Two different models of prognostic scores for 90-day mortality were generated by using these factors, including or excluding PS; both achieved specificities of more than 85% and sensitivities of approximately 50% when using a score cutoff of 5 or higher. These models were not superior to the previously published Royal Marsden Hospital score in their ability to predict 90-day mortality. CONCLUSION Patient selection using any of these prognostic scores will reduce non-drug-related 90-day mortality among patients enrolled in phase I trials by 50%. However, this can be achieved only by an overall reduction in recruitment to phase I studies of 20%, more than half of whom would in fact have survived beyond 90 days.

Prior studies of the comparative performance of greenfields and acquisitions have advanced competing arguments, with some arguing that greenfields should outperform acquisitions because acquisitions are costlier to integrate, and others that acquisitions should outperform greenfields because greenfields suffer from a liability of newness. Moreover, while the costs of integration and the liability of newness are at their greatest during a subsidiary's first years, prior studies have tested their competing arguments on samples containing older subsidiaries. We extend these prior studies by (1) developing an institutional theory-based framework that simultaneously considers the costs of integration and the liability of newness, (2) recognizing that both types of costs vary with the level of subsidiary integration, and (3) focusing on the stage of their life during which subsidiaries predominantly incur these costs. To measure subsidiary performance, we ask managers of Dutch multinationals how their ex ante performance expectations compare to the subsidiary's ex post performance during its first two years. Analysing a sample of 191 foreign subsidiaries and controlling for entry mode self-selection and other factors, we find that acquisitions outperform greenfields at low and intermediate levels of subsidiary integration, but that greenfields outperform acquisitions at higher integration levels.
