In the process of coding open-ended questions, the evaluation of interjudge reliability is a critical issue. In this paper, using real data, the behavior of three coefficients of reliability among coders, Cohen’s K, Krippendorff’s α and Perreault and Leigh’s I r are patterned, in terms of the number of judges involved and the categories of answer defined. The outcome underlines the importance of both variables in the valuations of interjudge reliability, as well as the higher adequacy of Perreault and Leigh’s I r and Krippendorff’s α for marketing and opinion research.  相似文献

Abstract . A six-months run of the popular and long-lived newspaper cartoon, “Dick Tracy,” was analyzed in terms of the frequency with which certain characters were used, the location and setting in which they appeared and the criminal activity and law enforcement technique portrayed. Also studied were physical characteristics of criminals and police, and the use of violence. The results indicated the continued theme of the cartoonist, Chester Gould, was a “morality play,”i.e., the triumph of good over evil. All pictured criminals were either apprehended or killed as a result of police expertise, and police violence was both minimal and reactive. However, contrary to similar analyses of primetime television, the majority of offenses pictured were crimes against the American economic system, rather than violent crime, and offenders were disproportionately White, middle-aged males.  相似文献

Abstract . An empirical analysis of the property crimes, robbery, burglary and larceny, is presented for all 120 counties in Kentucky. While this analysis is based on an economic model of crime, certain sociological and legal variables are included as well in the system of equations. Overall, the empirical results support prior studies’findings with the exception that a quadratic relationship is found to exist between urbanization and each of the property crimes. Furthermore, neither the economic nor the non economic influences measured appear more important for affecting crime rates. Specifically, results indicate that the level of poverty, the degree of tourism, the presence of police, the unemployment rate and the apprehension rate all affect property crimes. In contrast, the length of sentence, the degree of industrialization, the level of public assistance payments and the proportion of youth in the county have no affect on property crime rates in these areas.  相似文献

Abstract . The tension between Henry George's reformism and his laissezfaire liberalism was resolved through a system of natural liberty George derived from the relation between Adam Smith's ethics and economics. Crucial for George's nonutilitarian philosophy of government was the interdependence between the moral sense (sympathy) and the prevailing socioeconomic order. In the appropriate institutional environment, the role of the government was diminished since the pervasive moral sense insured justice by monitoring the individual's pursuit of economic self-interest. In contrast, a defective socio economic order required government intervention. For example, land monopoly and the maldistribution of income undermined the role of sympathy, promoted excessive self interest and the breakdown of the system of natural liberty. Government action through the single tax eliminated the “fear of want,” restored an operative moral sense and guaranteed justice in society. Under these conditions, government can provide additional services for a growing society without being susceptible to “corrupt and tyrannous” behavior.  相似文献

In this paper, we are presenting general classes of factor screening designs for identifying a few important factors from a list of m (≥ 3) factors each at three levels. A design is a subset of 3m possible runs. The problem of finding designs with small number of runs is considered here. A main effect plan requires at least (2m + 1) runs for estimating the general mean, linear and quadratic effects of m factors. An orthogonal main effect plan requires, in addition, the number of runs as a multiple of 9. For example, when m=5, a main effect plan requires at least 11 runs and an orthogonal main effect plan requires 18 runs. Two general factor screening designs presented here are nonorthogonal designs with (2m− 1) runs. These designs, called search designs permit us to search for and identify at most two important factors out of m factors under the search linear model introduced in Srivastava (1975). For example, when m=5, the two new plans given in this paper have 9 runs, which is a significant improvement over an orthogonal main effect plan with 18 runs in terms of the number of runs and an improvement over a main effect plan with at least 11 runs. We compare these designs, for 4≤m≤ 10, using arithmetic and geometric means of the determinants, traces, and maximum characteristic roots of certain matrices. Two designs D1 and D2 are identical for m=3 and this design is an optimal design in the class of all search designs under the six criteria discussed above. Designs D1 and D2 are also identical for m=4 under some row and column permutations. Consequently, D1 and D2 are equally good for searching and identifying one important factor out of m factors when m=4. The design D1 is marginally better than the design D2 for searching and identifying one important factor out of m factors when m=5, … , 10. The design D1 is marginally better than the D2 for searching and identifying two important factors out of m factors when m=5, 7, 9. The design D2 is somewhat better than the design D1 for m=6, 8. For m=10, D1 is marginally better than D2 w.r.t. the geometric mean and D2 is marginally better than D1 w.r.t. the arithmetic mean of the maximum characteristic roots.  相似文献

Abstract . The American family farm is threatened by the combination of low, unstable commodity prices and high costs of machine and chemical technology. Overplanting, erosion, excessive taxation, and non-farm development diminish the best cropland. Government and corporate business policy have encouraged overproduction and soil abuse. To survive, the small farmer takes a second job or joins the urban industrial proletariat. No single national organization protects agriculture or equals the effective lobbying of business and unions for their own interests. “Modern” technology often produces less per land unit than traditional labor-intensive cultivation and costs more in terms of energy, capital, and depleted soil and natural resources. Usurious interest, archaic tax laws, and rapid rise of current technological production costs force insolvency of the small farm while facilitating expansion of giant agribusiness corporations, but technological innovation may have reached the point of diminishing returns. Meanwhile disruption of rural society continues, aggravating metropolitan overpopulation, unemployment, and social disorganization.  相似文献

E-Leadership and Virtual Teams   总被引:1,自引:0,他引:1  
In this paper we have identified some key challenges for E-leaders of virtual teams. Among the most salient of these are the following:
• The difficulty of keeping tight and loose controls on intermediate progress toward goals
• Promoting close cooperation among teams and team members in order to integrate deliverables
• Encouraging and recognizing emergent leaders in virtual teams
• Establishing explicit processes for archiving important written documentation
• Establishing and maintaining norms and procedures early in a team’s formation and development
• Establishing proper boundaries between home and work
Virtual team environments magnify the differences between good and bad projects, organizations, teams, and leaders. The nature of such projects is that there is little tolerance for ineffective leadership. There are some specific issues and techniques for mitigating the negative effects of more dispersed employees, but these are merely extensions of good leadership—they cannot make up for the lack of it.

Information technology makes it possible to build far-flung networks of organizational contributors, although unique leadership challenges accompany their formation and operation. This paper describes the growth of virtual teams, the various forms they assume, the kinds of information and support they need to function effectively, and the leadership challenges inherent in each form. We then provide workable, practical solutions to each of the leadership challenges identified.  相似文献

Increasing human and social capital by applying job embeddedness theory   总被引:4,自引:0,他引:4  
Most modern lives are complicated. When employees feel that their organization values the complexity of their entire lives and tries to do something about making it a little easier for them to balance all the conflicting demands, the employees tend to be more productive and stay with those organizations longer. Job embeddedness captures some of this complexity by measuring both the on-the-job and off-the-job components that most contribute to a person's staying. Research evidence as well as ample anecdotal evidence (discussed here and other places) supports the value of using the job embeddedness framework for developing a world-class retention strategy based on corporate strengths and employee preferences.To execute effectively their corporate strategy, different organizations require different knowledge, skills and abilities from their people. And because of occupational, geographic, demographic or other differences, these people will have needs that are different from other organizations. For that reason, the retention program of the week from international consultants won’t always work. Instead, organizations need to carefully assess the needs/desires of their unique employee base. Then, these organizations need to determine which of these needs/desires they can address in a cost effective fashion (confer more benefits than the cost of the program). Many times this requires an investment that will pay off over a longer term – not just a quarter or even year. Put differently, executives will need to carefully understand the fully loaded costs of turnover (loss of tacit knowledge, reduced customer service, slowed production, lost contracts, lack of internal candidates to lead the organization in the future, etc., in addition to the obvious costs like recruiting, selecting and training new people). Then, these executives need to recognize the expected benefits of various retention practices. Only then can leaders make informed decisions about strategic investments in human and social capital.

Executive SummaryEmployee turnover is costly to organizations. Some of the costs are obvious (e.g., recruiting, selecting, and training expenses) and others are not so obvious (e.g., diminished customer service ability, lack of continuity on key projects, and loss of future leadership talent). Understanding the value inherent in attracting and keeping excellent employees is the first step toward investing systematically to build the human and social capital in an organization. The second step is to identify retention practices that align with the organization's strategy and culture. Through extensive research, we have developed a framework for creating this alignment. We call this theory job embeddedness. Across multiple industries, we have found that job embeddedness is a stronger predictor of important organizational outcomes, such as employee attendance, retention and performance than the best, well-known and accepted psychological explanations (e.g., job satisfaction and organizational commitment). The third step is to implement the ideas. Throughout this article we discuss examples from the Fortune 100 Best Companies to Work For and many others to demonstrate how job embeddedness theory can be used to build human and social capital by increasing employee retention.  相似文献

Summary This paper studies the steady-state behaviour of a discrete-time, single-channel, first-come-first-served queueing problem wherein (i) the arrivals at two consecutive time-marks are correlated (ii) the service is accomplished in phases and (iii) the completion of phases at two consecutive time-marks are correlated. The probability generating function (p.g.f.) of the number of phases waiting and in service is obtained. Further, the p.g.f. of queue length is obtained for the case when each unit demands only one phase of service, and the mean queue length is derived therefrom. Finally, the p.g.f. and the mean queue length are discussed for the special cases, (i) r=0,R≠0, (ii) r≠0,R=0, (iii) r=0,R=0, (iv) r≠0,R=−I, (v) r=0,R=−I, (vi) r=−I,R≠0, (vii) r=−I,R=0, (viii) r=I,R≠0, (ix) r=I,R=0, (x) r≠0,R=I, (xi) r=0,R=I, where r andR are the respective coefficients of correlation between arrivals and completion of phases at two consecutive time-marks.  相似文献

Abstract . According to a line of European social philosophers from Marx to Habermas, the development of society is characterized by a process of rationalization, accompanied by alienation and objectification of labor and human relations, and more generally a degradation of what Jürgen Habermashas called the person's “life world.” But the facts about small and medium sized business, as disclosed by empirical investigation, offer a different picture, one of small and medium size enterprises (SME) with a number of attributes associated with social organization on a small scale, of e.g., personality and independence. These can provide a counterweight to its disadvantages and limitations and therefore can be seen as values from a social philosophical point of view. Economically the same attributes make SME vulnerable to the market power and competition of big business. The new technology offers threats to SME, but also opportunities.  相似文献

The U.S. military argues that homosexuals are unfit for service because their presence compromises military readiness and unit cohesion. Based on this assumption, it continues to discharge homosexuals at an average rate of approximately 925 per year. On the other hand, the extant research suggests that homosexuals are no more disruptive to military life than their heterosexual counterparts. By integrating the legal and scientific literature, this paper examines the soundness of the military’s assumptions and aims to improve our understanding of the issues involved. Within this context, the efficacy of the military’s “Don’t Ask, Don’t Tell, Don’t Pursue” policy and whether it is in the best interest of the military and its soldiers and sailors is discussed.

This article examines how the U.S. Department of Defense (DoD) and Hollywood collaborated to manufacture the blockbuster films Transformers (T) and Transformers: Revenge of the Fallen (TRF) to sell in global markets and to sell a positive image of DoD personnel, policy, technology, and practice to the world. T and TRF are global militainment films made by the “DoD‐Hollywood complex” to make money in markets and put the U.S. military before the world in a positive light. To show how, the article's first section defines the “DoD‐Hollywood complex,” presents a brief 20th‐century history of its formation, and describes the current DoD institutions, policies, and practices that fuse DoD publicity agencies to Hollywood filmmakers. The second section highlights how DoD assisted T and TRF's production and contemplates why Hollywood solicited DoD support. The third section shows how T and TRF put DoD in a positive light. The conclusion addresses some of the consequences of T and TRF with regard to democratic theory. By showing T and TRF to be global militainment commodities, this article interrogates the nexus of “reel” and “real” U.S. military power and sheds light on how DoD interacts with Hollywood studios to influence how it gets screened by entertainment media and seen by global spectators.  相似文献

We examine the econometric implications of the decision problem faced by a profit/utility-maximizing lender operating in a simple “double-binary” environment, where the two actions available are “approve” or “reject”, and the two states of the world are “pay back” or “default”. In practice, such decisions are often made by applying a fixed cutoff to the maximum likelihood estimate of a parametric model of the default probability. Following (Elliott and Lieli, 2007), we argue that this practice might contradict the lender’s economic objective and, using German loan data, we illustrate the use of “context-specific” cutoffs and an estimation method derived directly from the lender’s problem. We also provide a brief discussion of how to incorporate legal constraints, such as the prohibition of disparate treatment of potential borrowers, into the lender’s problem.  相似文献

Abstract . In the colonial period of U.S. history, American Indian tribes enjoyed the status of political sovereigns, and dealt as equals with the English Crown and colonial authorities. In the years following U.S. independence, legal, administrative, and military actions were used to redefine the meaning of tribal sovereignty. Conceptualizing these developments, “captive nations” refers to the limited sovereignty of tribes and their isolation and detachment from mainstream American society. Recently, natural resource development on their land and especially the discovery of energy resources has had a major impact on the structure of Federal-Indian relations and the political status of Indian tribes in American society. Willingly or unwillingly, many tribes are in the process of renegotiating their status with the Federal Government as a consequence of the resource development. As a result, these former captive nations are now more aptly described as “internal colonies.”  相似文献

Abstract . ‘Savages,’ as Europeans considered the Americans of ancient times, never built the great Mayan centers. The builders of great cities in Meso-America were a well-organized group with an adequate land base and a rather sophisticated technology. From 300 B.C. to 900 A.D. the Maya developed and perfected an agriculture-based economy with a well developed commerce, writing, art, science, religion and government, as well as an advanced architecture of monuments, palaces, temples and pyramids. Their civilization reached intellectual heights unique in the Western Hemisphere. What conditions caused its decline and fall? Interpreting the geographic and historical record in the light of the relevant social sciences, one can say a complex of circumstances: ecological abuse, exploitation of the working population, mismanagement, militarism, bad weather, famines, and epidemics.  相似文献

Two random variables X and Y on a common probability space are mutually completely dependent (m.c.d.) if each one is a function of the other with probability one. For continuous X and Y, a natural approach to constructing a measure of dependence is via the distance between the copula of X and Y and the independence copula. We show that this approach depends crucially on the choice of the distance function. For example, the L p -distances, suggested by Schweizer and Wolff, cannot generate a measure of (mutual complete) dependence, since every copula is the uniform limit of copulas linking m.c.d. variables. Instead, we propose to use a modified Sobolev norm, with respect to which mutual complete dependence cannot approximate any other kind of dependence. This Sobolev norm yields the first nonparametric measure of dependence which, among other things, captures precisely the two extremes of dependence, i.e., it equals 0 if and only if X and Y are independent, and 1 if and only if X and Y are m.c.d. Examples are given to illustrate the difference to the Schweizer–Wolff measure.  相似文献

Abstract . Based on the Clarence E. Ayres (1891-1972) papers at the University of Texas, this study traces the continuity among thinkers such as Kant, Hegel, Veblen, Dewey, and Ayres; the latter was a leading institutional economist following Veblen's death. Publicly acknowledging his intellectual debt to Veblen and Dewey, Ayres drew from these men some idealistic assumptions as well as the historicism that is implicit in his technological determinism or instrumental theory of knowledge. Thorstein Veblen and John Dewey owed a great deal to the philosophical tradition of idealism, regardless of the devotion to naturalism in their systems. The origins of Ayres's technological theory of value are found in Veblen and Dewey writings and back of them the legacy of German idealism. The vital link was a mutual acceptance that freedom was expressed in a cultural and historical form, realized in human activity. It was a process.  相似文献
