The aim of this study was to assess spatial co‐occurrence of acute respiratory infections (ARI), diarrhoea and stunting among children of the age between 6 and 59 months in Somalia. Data were obtained from routine biannual nutrition surveys conducted by the Food and Agriculture Organization 2007–2010. A Bayesian hierarchical geostatistical shared component model was fitted to the residual spatial components of the three health conditions. Risk maps of the common spatial effects at 1×1 km resolution were derived. The empirical correlations of the enumeration area proportion were 0.37, 0.63 and 0.66 for ARI and stunting, diarrhoea and stunting and ARI and diarrhoea, respectively. Spatially, the posterior residual effects ranged 0.03–20.98, 0.16–6.37 and 0.08–9.66 for shared component between ARI and stunting, diarrhoea and stunting and ARI and diarrhoea, respectively. The analysis showed clearly that the spatial shared component between ARI, diarrhoea and stunting was higher in the southern part of the country. Interventions aimed at controlling and mitigating the adverse effects of these three childhood health conditions should focus on their common putative risk factors, particularly in the South in Somalia.  相似文献

Prior research on competitive dynamics has failed to offer tools to understand distorted patterns of competition that emerge from distinct institutional and historical contexts. Our analysis suggests that a joint effect of institutional rules, governance structures, and shared cognition plays a pivotal role in firm‐level competitive behavior and capability development. We show how globally significant market positions can result from specific institutional arrangements between firms and governments, especially if coupled with interfirm contractual commitments. Our results call for more attention to these interfirm commitments that are built on formal rules and governmental support, but whose impact they yet exceed.

Our study analyzes rivalry within and across markets of size‐defined strategic groups in the banking industry. We consider that, owing to group‐level effects, like efficiency and funding, the degree of rivalry of size‐defined strategic groups depends on whether the competitor is acting in the same or in a different market and whether the competing firms are within the same strategic group or in different groups. We estimate the effect of group interactions within and across loans and deposits markets on firm performance in the Spanish banking industry. We find evidences of rivalry as described in our hypotheses. Copyright © 2017 John Wiley & Sons, Ltd.  相似文献

We describe a double agency problem in firms' charitable donations. When managers have better knowledge about the effectiveness of donations and their altruistic preferences, it is difficult for shareholders to tell whether charitable donations are made for a strategic purpose or due to managerial altruism. We characterize the equilibrium donations in a heterogeneous competition model. We show that managerial altruism is a substitute for the effectiveness of donations, and excess donations cannot be prevented by a compensation scheme that reduces the interest conflicts between ownership and management. Under board authorization, the board will tolerate donations with high effectiveness and low altruism as well as donations corresponding to low effectiveness and high altruism. Under a penalty scheme, the altruistic manager will increase donations, in order to increase donation's strategic benefit to compensate for the loss from the penalty.

This article examines the efficacy of a ‘defense in participations’ policy consisting of competitors acquiring cross‐equity participations within the same industry to prevent hostile takeovers. This defense in participations strategy provides disincentive for raiders as partial ownerships increase market power of competitors and then reinforce the ‘outsider effect’. Also, we find conditions for a general result, which state that takeovers are less profitable in an industry with participations rather than in an industry without any capital links. We provide information to regulators about the positive social impact of cross participations in the context of mergers and expose an economic dilemma between a ‘laissez‐faire’ and an interventionist approach.

Managerial capacity builds over the years and the accumulated knowledge/practice affect the outcome of the period that follows, with long‐run/permanent effects on inefficiency. Therefore, predictions of the influence of managerial capacity on the time‐varying inefficiency, regularly estimated as overall efficiency, may be biased. This study analyzed the influence of farm management practices on both the persistent and residual efficiency, and evaluated how conclusions drawn about the effect of management practices are assessed if overall efficiency, instead of permanent and residual efficiency, is evaluated. Farm‐accounting data of Swedish pig producers and information from a survey related to managerial practices were used. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

In the era of a graying workforce, individuals and their employers are concerned with the impact of the graying workforce on the level of engagement at work. Contrary to the myths about older workers being less engaged, statistics have shown that the level of engagement is higher as people age. Within the broad framework of conservation of resources theory in the area of work engagement, the current study aims to clarify how older workers are more engaged at work than younger workers. Building upon socioemotional selectivity theory and continuity theory from a life‐span perspective, we explain how individuals gain more resources as they age, including the abilities to regulate emotion and to maintain a career identity. We argue that this positive relationship between age and resources explains why older people have high levels of work engagement. We tested our predictions with a sample of 613 workers in the United States. The study demonstrates that well‐regulated emotion and strong commitment to career mediate the positive relationship between age and work engagement simultaneously. These findings contribute to the understanding of an aging workforce's engagement in the workplace. © 2016 Wiley Periodicals, Inc.  相似文献

Drawing on conservation of resources theory, this study examined the link between negative mentoring experiences (i.e., interpersonal problems) perceived by mentors and their work‐family conflict (WFC) by focusing on the mediating role of emotional exhaustion and the moderating role of revenge. The results of a field survey of 187 mentors in China supported all of our hypotheses, indicating that interpersonal problems perceived by mentors were positively related to their WFC. This relationship was also found to be mediated by the mentors’ emotional exhaustion. In addition, revenge against protégés was found to moderate the main effect of interpersonal problems on emotional exhaustion and the indirect effect of interpersonal problems on WFC. Specifically, revenge exacerbated the positive relationship between interpersonal problems and emotional exhaustion. Further, emotional exhaustion mediated the indirect effect of interpersonal problems on WFC when the level of revenge was high, but not when it was low. The findings of this study provide insightful theoretical contributions and managerial implications that indicate new directions for research related to mentoring and work‐family relationships. © 2016 Wiley Periodicals, Inc.  相似文献

Human resource (HR) managers’ commitment to their occupation (HR) leads to the proper delivery and implementation of HR practices and, therefore, is deemed as a critical factor for the success of HR practices. Based on sociocognitive, human capital, and signaling theories, this study examines: (a) HR managers’ own and their chief HR officer's (CHRO) HR‐specific human capital as antecedents of their commitment to HR, and (b) the mediating mechanism through which the CHRO’s HR‐specific human capital positively influences HR managers’ commitment to HR. Based on 146 HR managers from 146 organizations in South Korea, the findings of the current study suggest that HR managers with higher levels of HR‐specific human capital and those working with CHROs with higher levels of HR‐specific human capital tend to have higher levels of commitment to HR. In addition, CHROs with higher levels of HR‐specific human capital positively influence HR managers’ commitment to HR by signaling to them that HR and its function are valued and cared about by their organizations. Theoretical and practical implications of this study are discussed along with study limitations and further research directions. © 2015 Wiley Periodicals, Inc.  相似文献

“Worthless,” “money burning,” or “black holes” is how media and professionals describe compliance practices today. Practitioners are unenthusiastic about control systems, codes of conducts, and systems for compliance management that are increasing in volume but not in effectiveness. In order to help practitioners clarify what actually makes employees comply with their compliance program, this study examines intrinsic and extrinsic motivators of 119 employees from procurement and sales. We contribute to the existing motivation literature, testing the self‐determination theory in low and high hierarchical levels. Our findings show that intrinsic motivators are more strongly and positively related to compliance intention on higher hierarchical levels than the lower ones. However, employees from higher hierarchies show overall less compliance intention than employees from lower hierarchies. © 2015 The Authors.
