Improving on truncated linear estimates of exponential and gamma scale parameters

We consider the problem of estimating the scale parameter of an exponential or a gamma distribution under squared error loss when the scale parameter θ is known to be greater than some fixed value θ₀. Natural estimators in this setting include truncated linear functions of the sufficient statistic. Such estimators are typically inadmissible, but explicit improvements seem difficult to find. Some are presented here. A particularly interesting finding is that estimators which are admissible in the untruncated problem which take values only in the interior of the truncated parameter space are found to be inadmissible for the truncated problem.     

Exploring structure-effectiveness relationships in nonprofit arts organizations

The authors examined nineteen nonprofit performing arts organizations, investigating the distribution of influence among organizational members, the grouping of volunteers and staff in organizational structures, and the effectiveness of the organizations. The organizations' effectiveness was assessed using multiple performance indicators. The analysis revealed five groupings or configurations of influence, which correlated to the organizations exhibiting the highest and lowest levels of organizational effectiveness. The authors conclude that a variety of structures are associated with good performance but structural dysfunctions are associated with organizational failure, and that members' commitment to an organization's structure is an important element of success.     

Retrospective on the utility theory of von Neumann and Morgenstern

This article offers an exegesis of the passages in von Neumann and Morgenstern (1944, 1947, 1953) that discuss their conception of utility. It is occasioned by two factors. First, as we approach the semicentennial of the publication of Theory of Games and Economic Behavior, its immense impact on economic thought in the intervening years encourages serious reflection on its authors' ideas. Second, misleading statements about the theory continue to appear. The article will have accomplished its purpose if it helps others appreciate the genius and spirit of the theory of utility fashioned by John von Neumann and Oskar Morgenstern.     

The influence of peers and parents on youth life satisfaction in Hong Kong

This investigation attempts to measure the relative influence of peer and parental influence on the perceived life satisfaction of two groups of secondary students in Hong Kong. Data on 1906 students from 30 schools were collected through the use of a self-administered questionnaire. Respondents were asked to rate their level of satisfaction on 26 different domains of life on a seven-point scale, ranging from very satisfied to very dissatisfied, as well as their satisfaction with life in general. These 26 items were combined to form six summary indices of life satisfaction: school life, family life, acceptance by others, government, media, and living environment. Two independent variables were used in the analysis of life satisfaction: peer orientation, and parent orientation. Both are composite indices and measure the adolescent's attachment to and identification with his peers or parents. It was found that parent orientation is a better predictor of life satisfaction than peer orientation. Adolescents who are high on parent orientation are more satisfied with every domain of life. They are also more satisfied with life in general. The relationship between peer orientation and life satisfaction is not a clear-cut one. Adolescents with strong peer orientation are more satisfied with school, media, government, and acceptance by others, but are less satisfied with family. There is no significant relationship between peer orientation and environment. The younger adolescents in our sample tend to perceive a higher level of satisfaction than the older adolescents in every domain of life as well as life in general.     

Bringing Business into Sociotechnical Theory and Practice

Current developments in the sociotechnical framework address a number of vital issues that failed to occupy the high ground in its formative years. These include: (i) the purpose of the systems, to create customer value under social and resource constraints, (ii) the context or external business environment, and (iii) the dynamics of the sociotechnical system. Due attention to the dominant issues of purpose, context, and their dynamics make it more meaningful to speak of sociotechnical business systems (STBS) and organizational learning instead of sociotechnical systems (STS) and individual learning. In STBS each unit in an organization has business responsibilities and goal-based couplings with its environment and focuses on the creation of customer value. The implications of this shift from STS to STBS are discussed and illustrated with current research and two summary case studies.     

Axiomatizations of the normalized Banzhaf value and the Shapley value

A cooperative game with transferable utilities– or simply a TU-game – describes a situation in which players can obtain certain payoffs by cooperation. A solution concept for these games is a function which assigns to every such a game a distribution of payoffs over the players in the game. Famous solution concepts for TU-games are the Shapley value and the Banzhaf value. Both solution concepts have been axiomatized in various ways. An important difference between these two solution concepts is the fact that the Shapley value always distributes the payoff that can be obtained by the `grand coalition' consisting of all players cooperating together while the Banzhaf value does not satisfy this property, i.e., the Banzhaf value is not efficient. In this paper we consider the normalized Banzhaf value which distributes the payoff that can be obtained by the `grand coalition' proportional to the Banzhaf values of the players. This value does not satisfy certain axioms underlying the Banzhaf value. In this paper we introduce some new axioms that characterize the normalized Banzhaf value. We also provide an axiomatization of the Shapley value using similar axioms. Received: 10 April 1996 / Accepted: 2 June 1997     

Reading,writing and word processing: Toward a phenomenology of the computer age

Ethnographers read cultures and in writing inscribe memory into texts; in literature, a reading is a dialogue with a writer through the medium the text, and writing translates text into action. In a study of humanists using the microcomputer as a writing technology, changes were perceived in the phenomenology of writing, the writer's relation to the text, and the relation to the reader. Typists remarked that the computer enabled them to recover a spoken voice because the screen gave the text a processual and temporal form which replaced the inflexible typed page. Handwriters often remarked that the computer changed humanistic craft labor into industrial production: the screen gave privilege to the lexical in place of the graphic; the sentence replaced the paragraph as a unit of meaning; writing became a medium for transmitting information rather than an artistic performance. Humanists perceived that technical norms were embedded in technical culture and software, and that the computer marked a shift in the reward structure of their professions toward productivity and efficiency. This suggests three issues for the writing crafts of ethnographers. Electronic memory may replace the interpretive text, making fieldnotes public and treating them as information. The technical capacity to organize fieldnotes in data bases may shift the fieldworker's conception of knowledge from interpretation to information. And consuming the norms and concepts of technical culture may shift the craftlike norms of the field worker's culture.

Scientific management and class relations

Conclusion It has been the contention of this article that the true significance of the scientific management movement lies in what it can tell us about the engineering profession. Scientific management was not simply capitalist ideology, nor were the engineers who developed it simply the prisoners of capitalist ideology. Instead, scientific management was the product of the insertion of once-independent engineers into the complex, collective labor process in large corporations. It reflects both their inability to break loose fully from the dominant ideology and the fact that their interests as engineers were in conflict with the interests of their capitalist employers.The significance of this point, however, lies beyond the experience of turn-of-the-century shop culture engineers. For, if even as unpromising a group as the scientific managers could develop a program with implications inimical to the interests of capital, what of other, less commercialized groups? We have already seen that the early school-based engineers initiated a professionalizing project that included a claim to autonomy that was incompatible with the needs of their employers. It seems clear that the engineer's status as an employee, albeit an employee in an ambiguous position in the labor process, constitutes a basis for the development of conflicts with capitalist employers. This has been the thrust of our earlier discussion of the process of class formation. Gramsci's analysis of the situation of engineers in capitalist class relations, then, may not be without foundation:With the urban intellectuals it is another matter. Factory technicians do not exercise any political function over the instrumental masses, or at least this is a phase that has been superseded. Sometimes, rather, the contrary takes place, and the instrumental masses, at least in the person of their own organic intellectuals, exercise a political influence on the technicians.It may very well be that engineers, given a more militant labor movement, a more penetrating ideology, or a weaker capitalist class, could find themselves on the same side as more subordinate employees in conflicts with their employers.It is all the more important, then, that we understand the process by which American engineers have been domesticated. This has not happened automatically; far from it. Although there are ambiguities in the engineer's situation that make this process easier, the rapprochement of engineers with capital has had to be made. In this regard, the active intervention of business interests has been of particular importance, especially their efforts in fostering among engineers a safe variant of professionalism.Nor does this historical lesson apply only to engineers. For, there are other professional occupations that, increasingly, find themselves in situations comparable to engineers. Accountants, nurses, teachers, even certain kinds of lawyers have long been employed in large numbers by complex organizations. More recently, even doctors have begun to experience the condition of being an employee. For each of these occupations, we must avoid the easy assumption that there is something inherent in their social structural position that leads them into an accommodation with capital. On the contrary, as with engineers, we must stress the existence of real conflicts generated by capitalist relations of production, and then examine each occupation historically, asking what specific circumstances explain why its members do or do not enter into explicit conflict with their employers. However, while we must be aware of the possibility that professionals can (and sometimes do) enter into conflict with their employers, we also need to be sensitive to the complexity of the structural position of many professionals. Many professionals find themselves in positions of authority of some kind - either over subordinate workers in the case of engineers, or over clients in the case of doctors. This can be conducive to the attitude that the professionals' interests are different from those of the groups over which they have authority, or that their interests are the same as their employers'. Alternatively, as we saw in the case of engineers, this structural ambiguity may promote the formation of narrow occupational ideologies among professionals - i.e., the idea that their interests differ from those of both employers and subordinates. Therefore, while we need to be aware of the existence of employer/ professional conflict, we also need to recognize the existence of barriers to, and complexities within, the evolution of such conflicts.It is with this in mind that this article has stressed the importance of developing an adequate approach to the process of class formation. To restate briefly some of the arguments made earlier, the process of class formation in capitalist society is set in motion by the antagonisms inherent in capitalist relations of production. This is not, however, all that we need to know about the process of class formation - we also need to recognize the existence of both objective and historical barriers to this process. Nevertheless, one must be clear about what exactly these barriers are. There is, for example, an important difference between the relations of production that constitute class in the first place and workers' functions in the labor process. Similarly, one should not confuse barriers to the process of class formation with full-fledged class divisions. If we fail to distinguish among these various factors, we will be in danger of artificially placing a class barrier between engineers and other forms of wage-labor. If, on the other hand, we do make these distinctions, we will be able to account for both engineers' opposition to their employers and their domestication.

An analysis of simple counting methods for ordering incomplete ordinal data

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.
