We explore the mechanisms through which subnational informal institutions exacerbate or ameliorate voids in national formal institutions. Informed by a within-country, cross-sub-region case comparison, we find two exacerbating mechanisms: Competition between the logics embedded in national and subnational institutions and the sabotage of a formal national institution by a void in a subnational informal institution. We also find two ameliorating mechanisms: Strong subnational informal institutions substitute for weak national institutions and bridge voids in formal institutions. Finally, we identify the conditions of expectation alignment and engagement associated with the competition, sabotage, substitution, and bridging mechanisms. Our findings contribute to institutional theory by providing a more subtle and contingent understanding of the interaction between informal and formal, and subnational and national, institutions. Our results also suggest ways in which constrained managers and bureaucrats can reduce the effects of voids in national formal institutions. 相似文献

A Bayesian approach to object matching is presented. An object and a scene are each represented by features, such as critical points, line segments and surface patches, constrained by unary properties and contextual relations. The matching is presented as a labeling problem, where each feature in the scene is assigned (associated with) a feature of the known model objects. The prior distribution of a scene's labeling is modeled as a Markov random field, which encodes the between-object constraints. The conditional distribution of the observed features labeled is assumed to be Gaussian, which encodes the within-object constraints. An optimal solution is defined as a maximum a posteriori estimate. Relationships with previous work are discussed. Experimental results are shown. 相似文献

Within risk theory a key fissure has emerged. On the one hand, objectivist theories continue to treat risk as a measurable entity, while on the other, subjectivist accounts approach risk as a socially constructed phenomenon. Arguably, we need to transcend this false opposition and harmonize important insights from both approaches. Building on an earlier paper in this journal, the author tries to achieve this synthesis by applying Bhaskar's critical realist perspective to this contested area. The reconciliation of objectivism and subjectivism within critical realism, it is argued, redirects our attention to the deep‐seated causes of harm or the underlying mechanisms that, when activated, give rise to situations involving risk. The paper concludes by reviewing the implications of these ideas for child and family social work. It is here that connections are made with attachment theory and the recent interest in childhood resilience. 相似文献

Recent work in the sociology of professions highlights the central importance of abstract discourse in professionalization processes. Drawing on the work of Kenneth Burke, I argue that broadening the focus of analysis from "abstract discourse" to "narratives of expertise" will provide the ability to (1) more clearly analyze the social conditions that are conducive to the efficacy of abstraction as a basis for a claim of expertise and (2) theorize and empirically examine the formation and maintenance of a collective professional identity. To assist in the reformulation of professionalization studies around narratives of expertise, I develop a modified extension of Burke's five key terms of dramatism (act, agent, scene, agency, and purpose). Burke's pentadic scheme enables researchers to show how narratives of expertise ground jurisdictional claims and the constitution of professional identity in one of the elements of pentad. I illustrate the empirical power of the pertadic scheme through an examination of claims of psychotherapeutic expertise, particularly claims of marital and familial expertise. 相似文献

Throughout the world, there is growing recognition of the important role Indigenous people play in natural resource management and conservation. Indigenous Land and Sea Management Programs (ILSMPs; which provide funds to Indigenous people to support Indigenous land management activities) are also known to generate social and economic benefits, although relative few of these co‐benefits have been quantified. Using northern Australia as a case study, we analysed data on ILSMP expenditure within three regional input–output tables, learning more about the size and distribution of their associated regional economic benefits. We found ILSMPs make a significant contribution to regional economies—with multipliers commonly exceeding that of other key regional industries such as agriculture and mining. We also found ILSMP expenditures make a larger contribution to Indigenous household incomes than they do to non‐Indigenous incomes—thus helping to close the (income) gap. They will continue to do so, provided the proportion of ILSMP money spent on Indigenous (compared to non‐Indigenous) incomes does not fall below a threshold amount. Rather than finding evidence of a trade‐off between socio‐ecological and financial/economic goals, our results suggest ILSMPs, known for their ecological importance, can also make a vitally important contribution to economic development in rural areas. 相似文献

Motivated by a recent paper on the effect of lead‐time variability reduction on safety stocks, we provide evidence of the recursive nature of safety stock changes. When lead times follow a gamma distribution we demonstrate that, for cycle service levels between .60 and .70, the reduction of lead‐time variability will first increase safety stock and then either recursively decrease safety stock or make it remain constant. We also numerically show the existence of the recursive effect. A two‐by‐two matrix is introduced to assist managers in making decisions regarding safety stock policy. 相似文献
