Conclusions I began this article with Colin Campbell's lament about the productionist bias in sociology and the related point that most sociologists concerned with consumption have ignored private meanings and small-scale structures in favor of public meanings and large-scale structures. This article calls attention to and builds on an emerging alternative approach to what happens after production, using an understanding of the social nature of objects that springs from Marcel Mauss's distinction between gifts and commodities.Mauss's model directs attention to the conflict in industrial societies between the two realms of commodity exchange and gift exchange, which I have cast as the conflict between the world of work and the world of family, and as the contrast between commodities and possessions. Thus, the model directs attention to the fact that objects are not simply transformed in production and displayed in consumption. However important these facts may be for understanding objects and society, they do not exhaust the important ways that people experience, use, and think about the objects that surround them. In particular, Mauss's model throws into relief the problematic nature of the objects that surround us and that we use in our social relations. And in doing so it directs attention to the ways that people try to reconstruct and redefine those objects by transforming them into personal possessions. This transformation makes objects acquired as commodities suitable for gift transactions, and hence suitable for the key task of recreating social relationships and social identities, the task of creating, not merely defining, who we are and how we are related to each other.Although the Maussian model addresses many of the links between people in the worlds of work and the home, and many of the ways that objects are part of these links, I am concerned here primarily with the ways that people can appropriate commodities in the process of purchase: shopping. This concern with shopping points out the social significance of retail trade, which I take to include advertising and shopping. This is not simply a passive conduit between production and consumption. Instead, it is an important point at which objects begin to leave the realm of work, commodities, and commodity relations and enter the realm of home, possessions, and gift relations. Shopping is an ubiquitous activity in industrial society and one that is highly significant culturally: we spend vast amounts of time, energy, money, and attention on it. Doubtless part of the reason for this is utilitarian, for we need to buy to live, but it would be foolish to reduce the significance of shopping to some combination of the need of individuals to acquire in order to survive and the need of companies to generate demand in order to profit. Thus, retail trade needs to be seen as well as a set of relations and transactions between seller and buyer that define and are defined by the objects and services involved, their history, and their future. My focus on purchasing food in supermarkets has the advantage of throwing into relief the problem of appropriation, because of the impersonality of object and social relations in large, self-service supermarkets. However, the very extremity of this example can create a false impression. As I noted, in other forms of shopping the social relations between buyer and seller, like the social identity of objects, can be more personal. This personality can be real, as when buyer and seller know each other or where the object is hand-made or even unique. Alternatively, it can be more purely symbolic, as when the selling company touts itself or its employees as friendly and caring or where the manufacturer advertises the personal nature of its commodities. In some cases, indeed, the manufacturing or trading company can present itself in such a way that the company itself becomes the person with whom the purchaser transacts. In addition, because of the focus on the appropriation of commodities in purchasing, I have touched only briefly on production and the world of work more generally. As does life at home, so life at work involves the transaction of objects and labor. Relations at work, then, will shape and be shaped by the nature of what is transacted. Co-workers who transact things that are more clearly stamped with their own identity, as among service workers and craft producers, will likely have more personal relations with fellow workers than will those who transact things that are themselves relatively impersonal, as in assembly-line production. This variability in the objects and relations at work suggests that people will have diverse understandings of work, and hence of manufactured objects more generally, which will affect the need they feel to appropriate commodities. In all, though, the point of this article is simple. People use objects to create and recreate personal social identities and relationships, and in industrial capitalist societies these objects are likely to be produced and purchased as commodities and understood as manufactures in Miller's sense. Our experience with and understanding of the production and sale of objects will affect the way we use them in transactions that create and recreate social identity and relationship, and will affect our understanding of the social identities and relationships that are created and recreated. Thus, the objects that people use in social relationships mediate between realms of economy and society, between the public realms where those objects are produced and distributed, and the private realms where those objects are transacted as part of social reproduction. The fact of this mediation and its effects on people's understanding of objects and social relations deserve careful attention.

Consider a randomized trial in which time to the occurrence of a particular disease, say pneumocystis pneumonia in an AIDS trial or breast cancer in a mammographic screening trial, is the failure time of primary interest. Suppose that time to disease is subject to informative censoring by the minimum of time to death, loss to and end of follow-up. In such a trial, the censoring time is observed for all study subjects, including failures. In the presence of informative censoring, it is not possible to consistently estimate the effect of treatment on time to disease without imposing additional non-identifiable assumptions. The goals of this paper are to specify two non-identifiable assumptions that allow one to test for and estimate an effect of treatment on time to disease in the presence of informative censoring. In a companion paper (Robins, 1995), we provide consistent and reasonably efficient semiparametric estimators for the treatment effect under these assumptions. In this paper we largely restrict attention to testing. We propose tests that, like standard weighted-log-rank tests, are asymptotically distribution-free -level tests under the null hypothesis of no causal effect of treatment on time to disease whenever the censoring and failure distributions are conditionally independent given treatment arm. However, our tests remain asymptotically distribution-free -level tests in the presence of informative censoring provided either of our assumptions are true. In contrast, a weighted log-rank test will be an -level test in the presence of informative censoring only if (1) one of our two non-identifiable assumptions hold, and (2) the distribution of time to censoring is the same in the two treatment arms. We also extend our methods to studies of the effect of a treatment on the evolution over time of the mean of a repeated measures outcome, such as CD-4 count.  相似文献

SUMMARY A two-sample version of the non-parametric index of tracking for longitudinal data introduced by Foulkes and Davis is described. The index is based on a multivariate U -statistic, and provides a measure of the stochastic ordering of the underlying growth curves of the samples. The utility of the U -statistic approach is explored with two applications related to growth curves and repeated measures analyses.  相似文献

Fit and Skill in Employee Selection: Insights from a Study of Headhunters   总被引:1,自引:0,他引:1  
We draw upon evidence from a qualitative study of headhunters to provide insights into the character and importance of candidate fit and skill for the selection of a broad range of white-collar employees. Headhunters suggest that the fit of a job candidate is assessed at two levels, one corresponding with a general compatibility with organization-level norms, culture, and strategy, the other corresponding more closely with traits and characteristics of the person or persons with whom the job candidate actually interviews. Skill—a factor which is largely neglected by those who tout the importance of fit—also plays an important and independent role in employee selection. Stalls that influence the selection of employees from a pool of candidates tend to be highly specific if not idiosyncratic, and take the form of what headhunters call hot buttons. We conclude by discussing the conceptualization, causes, and implications of fit; we also consider how the importance of fit and hot buttons challenges the explanatory logic of standard accounts of labor-market success.  相似文献

The Effects of Diversity on Small Work Group Processes and Performance   总被引:2,自引:0,他引:2  
Diversity is an increasingly important factor inorganizational life as organizations worldwide becomemore diverse in terms of the gender, race, ethnicity,age, national origin, and other personal characteristics of their members. The exact impact ofwithin-group diversity on small group processes andperformance is unclear. Sometimes the effect ofdiversity seems positive, at other times negative, andin other situations, there seems to be no effect at all.In this article, we suggest that these types of findingsmight be explained by using agroup-development model to examine theimpact of diversity on group processes and performance. Our modeluses concepts from Jackson et al.'s (1995), Milliken andMartins' (1996), and other models, as well as our ownconcepts, to show how diversity affects group development and performance. Among the conceptsincluded in the model are readily detectable personalattributes, underlying personal attributes, cognitiveparadigm dissimilarity, cognitive costs and rewards, diversity management skills, group behavioralintegration, and cognitive performance resources. In thepages that follow, we will explain each of thecomponents of the model and suggest specific hypotheses generated from the model.  相似文献

The original Arrow Theorem and many variants were stated with the Universal Domain assumption; but in economic situations, natural assumptions like monotonicity restrict the domain so that the Theorem does not apply. Since 1979, several authors have proved Arrow-type impossibility results in situations such as models with public goods or private goods; and a few have considered mixed-goods or stochastic alternatives models. This paper has similar results in models with mixed-goods, stochastic, and dynamic alternatives; the objects of preference can have any two features or all three. With suitable qualifications, the impossibility result continues to hold, as does the Arrow-inconsistency of arbitrarily small domains type of result I have established elsewhere.  相似文献

Constructionist notions have become commonplace in theoretical discussions of the self, but are seldom translated into consideration of specific social work practice concerns such as ADHD. Explorations of ADHD, on the other hand, typically emphasize a narrow, medically-oriented symptom picture that is devoid of the psychosocial context in which the so-called symptoms emerge. A transactional approach to the understanding of ADHD is advanced. This article promotes a link between constructionism and social work's psychosocial or person-in-environment perspective. Such a perspective supports approaches to the assessment of ADHD that illuminate larger cultural messages and their constraining influence on individual meaning-making. Intervention, conducted at multiple levels, must be geared to the establishment of more hopeful and affirming narratives.  相似文献

Software which allows interactive exploration of graphical displays is widely available. In addition there now exist sophisticated authoring tools which allow more general textual and graphical material to be presented in computer-based form. The role of an authoring tool in providing a graphical interface to a strategy for solving simple statistical problems in the context of teaching is discussed. This interface allows a variety of resources to be integrated. Specific examples, including the use of dynamic graphical displays in exploring data and in communicating the meaning of a model, are proposed. These ideas are illustrated by a problem involving the identification of the sex of a herring gull.  相似文献

Recent innovations in the structure of formal organizations suggest possible directions for the design of schools to bring about high achievement. The structure of output-driven in contrast to administratively-driven schools is described, and designs are described which address both the goal of high achievement and the goal of reduced inequality.An earlier version of this paper was presented as the author's Sorokin Lecture at the annual meeting of the Eastern Sociological Society, Boston, March 1993.  相似文献

Abstract Extract I have suggested that at a given birth order the probability of having a further pregnancy is greater when the last pregnancy had been spontaneously aborted than when it resulted in a birth.(2) Léridon,(3)in the course of a valuable paper on foetal wastage, presents data which, according to him, impugn my suggestion. I would like to question his claim.  相似文献
