Objectives. The purpose of this study was to extend research on the connection between school size and student outcomes by examining how school size was related to interpersonal processes and whether the interpersonal effects of school size varied by race/ethnicity. Methods. We applied multilevel modeling techniques to a sample of 14,966 students in 84 schools from the National Longitudinal Study of Adolescent Health. Results. Increasing school size was associated with decreasing student attachment to school and to teachers as well as extracurricular participation. Student attachment and teacher bonding diminished with increasing school size at a decreasing rate (reaching minimums in schools with between 1,700–2,000 students), but extracurricular participation dropped at a steady rate. These patterns did not differ substantially by race/ethnicity. Conclusions. The size of the educational institution influences interpersonal dynamics among actors in the institution and does so similarly across student groups. More generally, this research demonstrates the importance of organizational characteristics for social life.  相似文献

Analysis of survey responses from 371 public relations professionals in four-year colleges and universities revealed two constraints on how public relations is practiced. In the communication technician role, disclosure of information about the organization is constrained. In the manager role, participation in the decision-making process is constrained. Implications of these constraints for what can be communicated outside and what can be done inside the organization are discussed. Strategies for practitioners and educators in addressing constraints are presented, particularly in light of the recent movement toward Total Quality Management (TQM) in U.S. organizations.Duane Sweep is a marketing officer for the First American Bank in Minot ND; Glen T. Cameron is an assistant professor and RuthAnn Weaver Lariscy is an associate professor, both in public relations at the Henry W. Grady College of Journalism and Mass Communication, University of Georgia.  相似文献

Diffusion theory has typically focused on how communication, internal or external to a social system, leads to adoptions and diffusion of an innovation. We develop a diffusion and substitution model based on a somewhat different perspective. In some cases, progressive improvements in product attributes and/or continual cost reduction seem to be a key driver of the diffusion process. For example, after introduction of the 5.25‐inch disk drive, its capacity continually increased, and accordingly, so did customer willingness‐to‐pay. Our model is based on a linear reservation price framework, in which a product is described by its depth (defined as the difference between a product̂s maximum reservation price and its production cost), and its breadth (related to the slope of its reservation price curve), indicating how broadly it appeals across various customer segments. Because of changes in product depths and breadths over time, customers who previously preferred the old product may later prefer the new product, thus creating the diffusion process. While the Bass model describes diffusion as a function of the coefficients of innovation and imitation, in our model, it is described by the coefficients of depth and breadth (the rates of change in relative depth and breadth), along with an S‐coefficient that we associate with the technology S‐curve. We fit our model to data from the disk‐drive and the microprocessor industries.  相似文献

In this paper, we examine the suggested link between product architecture (i.e., the extent to which a product is modular vs. integral) and supply chain configuration (i.e., whether the product development is done internally by the manufacturer in an integrated supply chain or in collaboration with a supplier in a decentralized supply chain). Our model suggests that the choice of product architecture depends on firm, market, and product characteristics in addition to supply chain structure. In contrast to other studies, we find that the optimal mapping from architecture to supply chain structure is not always one‐to‐one. A decentralized supply chain may be associated with a more integral product when the technical collaboration penalty is not excessive and suppliers have significantly superior product development capabilities. Furthermore, in a decentralized supply chain, the nature of the relationship between the original equipment manufacturer and its supplier (adversarial or collaborative) plays a role in the choice of product architecture: modular architectures are more likely when the parties have adversarial relationships, while long‐term trust‐based relationships facilitate more integral product architectures.  相似文献

Exaggerated projections of the 3rd-person effect of crisis news on target groups may play a key role in escalating corporate crises. A 2 (locus of control: internal vs. external) × 2 (product category of crisis: food vs. laptop) experiment found that the 3rd-person perception varies as a function of product category. Our results indicated that in a laptop product category crisis, participants perceived target audiences to be more influenced than themselves when locus of control was internal rather than when it was external. This study delved into the potential effect on target groups and the corporation resulting from possible exaggerated perceptions of the impact of the crisis on the target groups. This perception may prompt or even pressure target audiences to react more strongly in keeping with the perceived impact, not their actual concern with the crisis. In turn, corporations may respond to a target audience based on the reaction the target audience feels obligated to portray in response to perceived impact, not actual impact measured independently in various ways.  相似文献

The purpose of this paper is to determine the effects of off-farm employment on perceptions of quality of life. Data collected on 311 Western Ontario male and female farmers revealed that although most indicated satisfaction with their lives, some differences are apparent. Women employed off the farm report more areas of lower satisfaction than their male counterparts and men and women working solely on the farm. Low levels of satisfaction with time issues, leisure and exercise were most evident for employed women. Men employed off the farm report the most effects from time issues, satisfaction with the farm business, income and the environment. People working off the farm feel their farms are less successful and are more concerned with their environment. Whereas the farm family's pluriactivity enables many to hold on to herished aspects of the farming lifestyle for a while, its burdens are perceived to fall neaviest on female farmers especially if they have young children. The magnitude of their concerns about the quality of their environment and not being able to farm successfully suggests that many of these farmers would improve their quality of life by peeding up the transition out of farming before all their farm's equity is lost.  相似文献
