Public relations is a key activity for most chairmen of public companies and nationalized industries. It is somewhat suprising therefore how few large companies consider developing an explicit public relations strategy as part of their overall business plan. The reason for this may be partly due to the relatively low regard which senior line managers have for public relations managers and partly because there is a lack of understanding of the nature and use of public relations as a tool of strategic management. The purpose of this article is to discuss why and how business planners should pay more attention to developing explicit public relations strategies for their organizations.  相似文献

The social Work service in most Social Services Departments is organised in distinct geographically based units. Indeed, such units have become synonymous with social work teams. These “teams” rely heavily for their success, as responsive and resourceful units, on their ability to work together. The authors believe there are advantages in a collective approach to a team's decision making and service delivery. They describe a method for developing teamwork, centred around a study day, organised on the basis of structured participation and planned in a way which addresses a range of team concerns.

The programme used on the study day stresses the importance of clear objectives, agreed democratically, and the active involvement of all team members. Although this training method developed gradually and pragmatically it is based on a model of team development which identifies a progression through stages of team functioning. The model of learning emphasises change through participation in a climate of openness and trust.

Examples of a programme used by the authors, together with a report prepared as feedback to a team, are included as appendices.  相似文献

In May 2012, the Committee of Health and Medicinal Products issued a concept paper on the need to review the points to consider document on multiplicity issues in clinical trials. In preparation for the release of the updated guidance document, Statisticians in the Pharmaceutical Industry held a one‐day expert group meeting in January 2013. Topics debated included multiplicity and the drug development process, the usefulness and limitations of newly developed strategies to deal with multiplicity, multiplicity issues arising from interim decisions and multiregional development, and the need for simultaneous confidence intervals (CIs) corresponding to multiple test procedures. A clear message from the meeting was that multiplicity adjustments need to be considered when the intention is to make a formal statement about efficacy or safety based on hypothesis tests. Statisticians have a key role when designing studies to assess what adjustment really means in the context of the research being conducted. More thought during the planning phase needs to be given to multiplicity adjustments for secondary endpoints given these are increasing in importance in differentiating products in the market place. No consensus was reached on the role of simultaneous CIs in the context of superiority trials. It was argued that unadjusted intervals should be employed as the primary purpose of the intervals is estimation, while the purpose of hypothesis testing is to formally establish an effect. The opposing view was that CIs should correspond to the test decision whenever possible. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

This paper explores how Board Remuneration Committee (Remco) decisions about executive pay are influenced by pay consultants. Drawing on resource dependency theory and case study evidence from five companies, the paper illuminates the complexities of the pressures and processes confronting both Remcos and pay consultants in the determination of executive pay awards. In contrast to ‘managerial power’ arguments, it demonstrates that the Remcos are proactive in managing pay policy, conscientious in seeking to ensure that pay is appropriate and not over‐generous, and that pay consultants are independent and take their instructions entirely from the Remco. Nevertheless, Remcos' understandings of the wider pay environment, informed by the comparative data supplied by pay consultants, constructs a climate in which the Remcos come to perceive a need for periodic upward pay adjustments to ensure that executive remuneration is consistent with external benchmarks if they are to avoid recruitment and retention problems.  相似文献

Resolving paradoxes involving surrogate end points   总被引:1,自引:0,他引:1  
Summary.  We define a surrogate end point as a measure or indicator of a biological process that is obtained sooner, at less cost or less invasively than a true end point of health outcome and is used to make conclusions about the effect of an intervention on the true end point. Prentice presented criteria for valid hypothesis testing of a surrogate end point that replaces a true end point. For using the surrogate end point to estimate the predicted effect of intervention on the true end point, Day and Duffy assumed the Prentice criterion and arrived at two paradoxical results: the estimated predicted intervention effect by using a surrogate can give more precise estimates than the usual estimate of the intervention effect by using the true end point and the variance is greatest when the surrogate end point perfectly predicts the true end point. Begg and Leung formulated similar paradoxes and concluded that they indicate a flawed conceptual strategy arising from the Prentice criterion. We resolve the paradoxes as follows. Day and Duffy compared a surrogate-based estimate of the effect of intervention on the true end point with an estimate of the effect of intervention on the true end point that uses the true end point. Their paradox arose because the former estimate assumes the Prentice criterion whereas the latter does not. If both or neither of these estimates assume the Prentice criterion, there is no paradox. The paradoxes of Begg and Leung, although similar to those of Day and Duffy, arise from ignoring the variability of the parameter estimates irrespective of the Prentice criterion and disappear when the variability is included. Our resolution of the paradoxes provides a firm foundation for future meta-analytic extensions of the approach of Day and Duffy.  相似文献

The most serious long-term threat facing the world is the danger that human actions are producing irreversible, harmful changes to the environmental conditions that support life on Earth. If this problem is not overcome, there may be no viable world for our descendants to inhabit. Because this threat is caused by human population growth, overconsumption, and lack of resource conservation, social scientists have a vital role in helping our world escape ecological disaster and approach a sustainable level of impact on the environment—one that can be maintained indefinitely. Enormous changes to human lifestyles and cultural practices may be required to reach this goal. This article discusses major obstacles to this goal, describes a variety of motivational approaches toward reaching it, and proposes that we should view the achievement of sustainable living patterns as a superordinate goal—a war against the common enemy of an uninhabitable world.  相似文献

Objective: Behaviors of weight conscious drinkers (BWCD) include disordered eating, excessive physical activity (PA), and heavy episodic drinking. Considering that approximately 25% of the college students report BWCD, it is important to investigate what characteristics increase the likelihood of college students engaged in BWCD for both moderate and vigorous PAs. Participants: A total of 510 college students were recruited from a large, public southeastern university. Methods: Participants completed a cross-sectional survey during the spring 2015 semester. Results: Of 510 respondents, 11.2% reported moderate PA-based BWCD and 14.7% reported vigorous PA-based BWCD. Weight loss intention, BMI and Greek affiliation predicted both moderate and vigorous BWCD. Conclusions: Study findings suggest that Greek-affiliated students and students with weight loss intentions might be at an increased risk for BWCD. Along with promoting lower levels of alcohol consumption, college practitioners should consider discussing issues of weight and body image with college students as they relate to maladaptive drinking behavior.  相似文献
