This article suggests an alternative to the ratio estimator for estimating the total size of a subdomain of a population. The application that served as the genesis for this work is from auditing. The problem is to estimate the total of sales transactions that are not tax exempt from an audit sample of the population of nontaxed sales transactions. A superpopulation approach, which models the unit's probability of belonging to the subdomain as a function of its size, leads to a family of estimators. The simplest member of this famiiy is one in which that function is specified to be a constant. The optimal estimator for this model performs markedly better than the ratio estimator when the assumption is true and often performs better when it is not, though in that case it is biased. Stratification is shown to reduce this bias and at the same time make the ratio estimator more similar to the optimal estimator. A simulation experiment shows that the theoretical advantages hold in a real audit population.  相似文献

One ultimate test of the material value of identification in an organizational context is whether it relates to productivity. In this rare study of a business team in a global consumer goods company, we demonstrate a sales benefit of organizational identification when correcting for systematic between‐unit differences in sales. Findings also question the theoretical and practical meaning of ‘proximity’ in accounting for salience variations in identification – the best predictor of sales was the degree of identification with the superordinate business unit. Findings shed light on the scientific as well as managerial and business utility of the organizational identity concept.  相似文献

This study proves once again that too many press releases are poorly written and over-written, with long sentences and paragraphs, and poor syntax as well as weak and passive construction. In their use of press releases, journalists almost always have to make them simpler, shorter, easier to read, and less passive.The authors conclude that success in writing of press releases requires brevity and simplicity, shorter paragraphs, sentences, and words, and the elimination of the passive voice.Timothy Walters is an assistant professor of communication at Stephen F. Austin State University in Nacogdoches, TX. Lynne Walters is associate professor of journalism and Douglas Starr professor of journalism, both at Texas A&M University, College Station. Lynne Walters is currently a Fulbright professor at the American Journalism Center in Budapest, where her husband Timothy is also on a one-year appointment as a visiting professor.  相似文献

La forme que prend le ménage en milieu rural semble dépendre de facteurs structuaux tel l'accès aux ressources sans toutefois en être déterminée. Contrairement aux analyses qui soulignent seulement la présence d'un concensus au sein du ménage, nous considérons le ménage rural comme une unité politique qui implique des négotiations quotidiennes entre ses membres. Le concept d'hégémonie du ménage' est un outil analytique utile permettant d'aller au-delà des catégories 'conflit' et 'consensus' pour caractériser les dynamiques internes du ménage rural. Cette perspective est développée à l'intérieur d'une analyse de la dynamique entre les sexes dans le ménages ruraux de la côte de l'Équateur. Cet essai identifie certaines implications de cette approche en ce qui concerne les femmes et le développement.
Structural criteria such as access to land may condition the form the rural household takes but they do not determine it. It is suggested here, in contrast to analyses which emphasize household consensus, that we appreciate the farm household as a political unit involving daily negotiations between household members. The concept of 'household hegemony' is introduced as a helpful analytical tool which goes beyond conflict versus consensus dynamics. This approach is developed through a consideration of the gender dynamics within rural households in coastal Ecuador. Specific implications for women and development issues are considered.  相似文献

We experimentally examined social contextual factors that might moderate children's dislike for aggressors and for victims of aggression, by varying both the aggressor's behavior (aggressive toward multiple children versus aggressive only toward one child) and the victim's behavior (passive versus assertive). Children (117 male and female fourth to sixth graders) listened to one of four scenarios describing the experiences of boys at a summer camp and rated how much they liked the aggressor, the victim, and the other children in the scenario; children also reported how much they thought the aggressor, victim, and others liked each other. Overall, and consistent with previous research, children disliked aggressors the most, followed by victims and then by the other children in the scenarios. Importantly, children's liking was influenced by the social context in which the aggression occurred, particularly in regards to how the victim responded. Aggressors (general or focused) were liked more if their victim was assertive rather than nonassertive. Furthermore, children liked nonassertive victims less than assertive victims, particularly a nonassertive victim in response to a general aggressor. Inferred liking among the group members also was dependent on the social context of the provocation. This research highlights the need to consider aggression as more than a set of behaviors. Aggression is a social event embedded within a social context and interpersonal relationships must be considered.  相似文献

Two-tier pay plans, under which new hires are paid on a lower pay scale than existing employees, have been used with increasing frequency in union-management contracts. The two-tier phenomenon appears to be associated with the wider concession bargaining movement that began in the early 1980s. In this study, management attitudes toward and forecasts about two-tier pay plans are explored by means of a questionnaire survey. In general, the management community is found to be optimistic about the spread and utility of two-tier pay plans in the near term. Managers in firms that actually have two-tier plans are more enthusiastic about their impacts than other managers. Over a longer term, however, the managers surveyed tend to believe that separate wage scales under two-tier plans will eventually be merged into a unified scale. The authors would like to thank Maury Pearl and Gwang-Gi Baek for research assistance on this study.  相似文献

To participate or not to participate: that is the question   总被引:1,自引:0,他引:1  
Do I wish to participate or not to participate in this program? That is the question that young people ask themselves when considering a new opportunity. What can be done to increase the likelihood that they will choose to participate in out-of-school-time (OST) programs? This chapter describes a qualitative study that examined reasons for participating or not participating in OST programs. Some common reasons emerged, but the study also revealed differences among youth from different ethnic groups. It is clear that those who design and conduct programs must understand the processes through which diverse adolescents initiate their participation in programs and either persist or drop out. Given the apparent benefits of active participation in youth programs, it is important to remove barriers and increase access and, equally important, design programs that are of interest to youth in the contexts in which they live.  相似文献

One solution to the underutilization of workplace accommodations is to use teleconferencing technology to conduct remote assessments, effectively expanding the geographical area that experienced rehabilitation specialists can cover. However, such an effort requires a highly structured and comprehensive assessment protocol. This paper reports on the analysis of 53 existing assessments to develop a conceptual framework for assessment and the use of that framework to evaluate the applicability of 10 work-related assessment protocols for remote tele-assessment. While none of the 10 protocols were found to be sufficiently comprehensive for our purposes, the conceptual framework itself will serve as an important tool to structure a new comprehensive protocol that will be developed. Moreover, the framework can also be used by providers of workplace assessments to evaluate the suitability of any assessment protocol to meet the needs of any particular individual or workplace situation.  相似文献
