The paradox of multiple elections   总被引:1,自引:0,他引:1  
Assume that voters must choose between voting yes (Y) and voting no (N) on three propositions on a referendum. If the winning combination is NYY on the first, second, and third propositions, respectively, the paradox of multiple elections is that NYY can receive the fewest votes of the 23 = 8 combinations. Several variants of this paradox are illustrated, and necessary and sufficient conditions for its occurrence, related to the “incoherence” of support, are given. The paradox is shown, via an isomorphism, to be a generalization of the well-known paradox of voting. One real-life example of the paradox involving voting on propositions in California, in which not a single voter voted on the winning side of all the propositions, is given. Several empirical examples of variants of the paradox that manifested themselves in federal elections – one of which led to divided government – and legislative votes in the US House of Representatives, are also analyzed. Possible normative implications of the paradox, such as allowing voters to vote directly for combinations using approval voting or the Borda count, are discussed.

Caught between their child and doing the right thing, families of chronic juvenile delinquents often experience a series of injustices in the name of justice. Attempts by the system to correct the delinquency problem often result in the imposition of values and beliefs that negate the family's values, experiences and meanings of their child's behavior. The Ecosystemic Natural Wrap-around (E.N.W.) model attempts to respectfully account for the many influences that maintain problematic interactions, both internal and external, in the nuclear family of chronic juvenile delinquents. The model focuses on a variety of interventions at different levels and contexts, building on the strengths of the family, using the extended family and fictive kin networks, and clarifying the meanings associated with problematic behavior for the multiple players. The model proposed is an integrative theoretical approach, emphasizing systems theory and constructivism.  相似文献

An analysis of the field of higher education reveals a surprisingly large number of classification errors within the (US) National Taxonomy of Exempt Entities database. Of the nearly 4,000 non-profit entities coded within the universe of institutions of higher education, we estimate that approximately 60 per cent were incorrectly included (Type II errors). Institutions incorrectly excluded from the higher education universe (Type I errors) represent roughly 10 per cent of the institutions coded correctly. These errors result primarily from assigning codes on the basis of the names of organisations (for example, College Park Towers is classified as a college, when it is in fact a housing complex for senior citizens) and from trying too hard to assign codes in ambiguous situations. The consequences can be significant for the users of these data, and we recommend raising bright warning flags while simultaneously enlisting the help of the entire non-profit sector in improving the classification coding process.The authors are with The Andrew W. Mellon Foundation. In addition to our colleagues on the staff of the Foundation, we wish to thank Helmut Anheier, Ted Bozovich, Harvey Dale, Virginia Hodgkinson, Stephen Noga and Christopher Toppe for helpful suggestions.  相似文献

An analysis of simple counting methods for ordering incomplete ordinal data   总被引:1,自引:0,他引:1  
Measurement in the social sciences often involves an attempt to completely order a set of entities on the basis of an underlying attribute. However, limitations of the measurement process often prevent complete empirical determination of the desired ordering. Nevertheless, the ordinal data obtained from the measurement process can be used in attempting to recover or construct more of the underlying order than is provided by the data. Previous research (Fishburn and Gehrlein, 1974a) has shown that a simple one-stage construction method, referred to as the cardinal rule, is fairly effective in correctly identifying ordered pairs in the underlying linear order that are not identified by the measurement process. The present paper re-examines the cardinal rule from the perspective of construction methods based on simple counting measures derived from the data, and argues that it is the best one-stage method in this class when a natural monotonicity assumption holds for the measurement process. The paper then examines two-stage construction rules that are based on the cardinal rule and the simple counting measures. It is shown that one of the two-stage rules gives better overall results than does the cardinal rule by itself.  相似文献

Recent environmental changes have brought about modifications in the strategic planning practices of multinational businesses. These modifications in the strategic planning practices were studied through the medium of in-depth interviews with planners in a number of concerns. Of the several changes observed, predominant are the shortening of time horizons and the increase in flexibility. Equally noteworthy is the surprising lack of change in the social concern of a number of the organizations. This article summarizes a study of the effects of environmental changes on multinational-business planning.  相似文献

The question which, unfortunately, often goes unanswered, is whether a company's process of corporate planning is optimal. Furthermore, even if they wished to answer such a question there is little in the literature which can provide them with a direct, and explicit evaluative model. This paper examines the development of planning and the many different contributors towards its theoretical underpinning. Whilst recognizing that planning is a field which is a ‘semantic's jungle’ the authors carefully pick their way through the mine-field of misunderstanding and misquotation and clearly establish a base-line for evaluation and indeed propose a detailed methodology. It is hoped that this paper will be a fore-runner of many which will assist the executive in his important evaluative role concerning alternative planning approaches.  相似文献

Empirical research on strategic alliances has been limited because previous studies examined alliance outcomes, and the factors associated with them, from a single partner in a manufacturing alliance. Furthermore, many of these studies have been done from a transaction cost perspective and researchers have inferred opportunistic behavior, rather than directly measuring it and observing its actual relationship with alliance performance. Building on previous transaction cost theory and research, this study seeks to address these gaps by analyzing factors associated with both opportunistic behavior and alliance performance within a major service sector, namely the US healthcare industry. After controlling for asset specificity and alliance age, we found that partner trustworthiness and contractual safeguards were negatively related to opportunistic behavior. Furthermore, opportunistic behavior was negatively related to alliance performance, as hypothesized. Interestingly, mutual equity investments were found to be unrelated to opportunistic behavior, counter to transaction‐cost logic. These findings refine and extend the transaction‐cost economics perspective regarding our understanding of strategic alliance behavior and outcomes, and offer executives in service‐based industries some practical ideas for assuring favorable strategic alliance outcomes.  相似文献
