Over the last ten years the concept of ‘competence’ has emerged as a central concept for competitive strategy. Several rich theoretical streams have contributed an extensive array of frameworks, definitions and papers using the concept. There is now a need to integrate these many contributions. Indeed, some of the frustration expressed recently by academics may be due to the large volume of conversation and the low level of integration. A concept that is considered so useful that many writers have incorporated it in their work will be of little value if it takes on different meanings for every use. If competence is to be used to explain relationships among variables and to build richer understandings of the roots of competitive advantage, then the field needs to engage in a serious conversation that attempts to focus this concept. Competence needs to be understood in a way that is faithful to its theoretical roots, allows the multiple dimensions that underpin competitive advantage to be meaningfully integrated and is specific enough that meaningful differences can emerge when used as a variable in empirical research. This paper seeks to begin a conversation toward that end by presenting a conceptualization that meets all of these requirements. The paper builds its conceptualization around satisfying the elements of a dynamic model of the relationship between competence and competitive advantage.  相似文献

A necessary and sufficient condition for linear aggregation of SSB utility functionals is presented. Harsanyi's social aggregation theorem for von Neumann–Morgenstern utility functions is shown to be a corollary to this result. Two generalizations of Fishburn and Gehrlein's conditional linear aggregation theorem for SSB utility functionals are also established.  相似文献

The paper offers a (partial) review of the philosophy of postmodernism as it applies to social science in general and management and organization theory in particular. Initially, some of the main analytical perspectives of postmodernism and post-structuralism are explored, notably those relating to epistemology and ethno-industrial change. Subsequently, we review concepts which lie at the heart of the 'postmodern mood' in social philosophy and sociology; for example, representation, reflexivity, deconstruction and decentring. In so doing, we take reference to the works of Jean Baudrillard, Jacques Derrida and Jean-François Lyotard amongst others Finally, this philosophical assessment review forms the basis for an analysis of postmodernism as an emerging paradigm of management and organization theory. The works of key postmodernist writers in management and organization studies are reviewed and case examples of postmodern research presented.  相似文献

The paper draws on ethnographic fieldwork undertaken with a group of young men known collectively as the Bad Blue Boys (BBB)1. These young men use the supporting of a soccer team (Sydney United in the national league) as a means of parading nationalistic allegiance to their parent's homeland, Croatia. Given the history of crowd conflict at Australian soccer matches and the current trends within soccer officialdom to move the sport away from its traditional affiliation with ethnic communities, it is inevitable that the BBB have come into confrontation with agents of social authority, such as the police, during an afternoon at the football. The participant observation aspect of the research is used to discuss the interaction between the police and the BBB at soccer matches, while interviews with members of the BBB are recounted to reveal group attitudes held about the police. The paper is written to articulate with other academic contributions which have investigated the relationship between youth from non-English speaking backgrounds (NESB) and the police in contemporary Australian urban contexts. A leading contributor to such studies, Janet Chan, has commented, ‘Australian research specifically on police-ethnic youth relations [paints] a negative portrait’ (Chan 1994, p. 176). The portrait painted by the present study is intended for comparison with such research. At the outset it must be stressed that the findings are peculiar to the study and that no great claim is made for extrapolation. However, this is not to say that the study does not reflect trends in relations between NESB youth and police in Australian cities. On the contrary, a conclusion will be drawn which argues that ethnographic studies of particular ethnic youth groupings and subcultures facilitate a social mapping of police youth relations.  相似文献

There is now overwhelming experimental evidence that individuals systematically violate the axioms of Expected Utility theory. In reality, however, many economic decisions are taken by, or on behalf of, groups whose members have a joint stake in those decisions. This paper reports on an experiment in which pairs of individuals are tested for Common-Ratio inconsistencies. We find that the agreed choices of subject-pairs follow a pattern of inconsistency very close to that of individuals' choices. We also look for evidence that group participation increases the consistency of the individuals themselves. With one solitary exception, we find none.  相似文献

Beta-Bernstein Smoothing for Regression Curves with Compact Support   总被引:5,自引:0,他引:5  
ABSTRACT. The problem of boundary bias is associated with kernel estimation for regression curves with compact support. This paper proposes a simple and uni(r)ed approach for remedying boundary bias in non-parametric regression, without dividing the compact support into interior and boundary areas and without applying explicitly different smoothing treatments separately. The approach uses the beta family of density functions as kernels. The shapes of the kernels vary according to the position where the curve estimate is made. Theyare symmetric at the middle of the support interval, and become more and more asymmetric nearer the boundary points. The kernels never put any weight outside the data support interval, and thus avoid boundary bias. The method is a generalization of classical Bernstein polynomials, one of the earliest methods of statistical smoothing. The proposed estimator has optimal mean integrated squared error at an order of magnitude n −4/5, equivalent to that of standard kernel estimators when the curve has an unbounded support.  相似文献

The article begins by considering moves to establish Social Europe, alongside the European Unions single market, and the emphasis within the formulation of Social Europe on an employment-based model of social citizenship. This employment-based model is considered to be too limited for application to the social services. Accordingly, two other models are placed within the context of continuing European debate. These models are termed state clienthood and state-sponsored consumerism. The social democratic model of state cli-enthood is considered to be flawed by its neglect of the power exercised by the state over users of social services and by its lack of concern with individual needs. The potential of state-sponsored consumerism to open up questions concerning the rights of users of social services and responsiveness to their individual needs is explored and the conclusion is reached that, despite its inauspicious beginnings as part of the New Rights reform programme, this model has possibilities for enhancing social citizenship. Procedural rights offered by state-sponsored consumerism not only can extend social citizenship within existing social services provision but also can serve as a precursor to the wider participation of citizens in the social services, as the site of a continuing struggle around their rights.  相似文献

Dans cet article, nous examinons différents modèles de rapports avec les forces policières parmi des sous-populations hétérogènes de jeunes, dans les premiers stades de transition de leur carrière criminelle. Nous croyons que la recherche axée sur l'hétérogénéité et sur les premiers stades de la transition vers la criminalité peut nous renseigner sur les éléments de la dynamique comportementale - jusqu'ici ignorés - dans l'étude de l'apparition d'un comportement criminel et de sa persistance. À partir de données policières informatisées provenant d'une grande ville de l'ouest du Canada, nous utilisons certains modèles de survie basés sur des événements pour dégager des modèles d'apparition et de persistance de comportements criminels sur une période de six mois, dans les premiers rapports avec la police. Les résultats démontrent des modifications importantes à court terme dans le comportement criminel de sousgroupes de jeunes de niveaux différents. Certains semblent avoir un comportement criminel ponctuel, qu'ils abandonnent par la suite, tandis que d'autres continuent de se comporter en criminels, en augmentant la fréquence et le taux d'infractions. Toutefois, certains modèles hétérogènes existent au sein de ces sous-groupes de jeunes délin quants dans les premières phases de développement de la criminalité. We investigate distinctive patterns of police contacts among heterogeneous subpopulations of youths in the early transition stages of their criminal careers. We argue that research focussing upon heterogeneity and the initial transition stages of criminality can provide insights into behavioural dynamics previously overlooked in the study of the onset and development of criminal careers. Using computerized police archival data from a large western Canadian city, we employ event history survival models to estimate patterns of onset and persistence for delinquent careers over six-month intervals in the early stages of police contact. Our results provide strong evidence of meaningful short-term change in offending among multiple levels of youth subgroups. Some youths appear to offend only briefly and then desist, while others continue offending and at a higher rate. However, there also appear to be patterns of heterogeneity within as well as between these subgroups of young offenders during the early stages of criminal careers.  相似文献
