This paper explores the issues inherent in defining contracts for service delivery between the state and charitable organisations,
and in differentiating them from grants. It begins by making the point that there is no one correct definition of a contract;
rather, it is a function of its purpose. It then details our work in developing a definition of a contract within the national
accounting tradition, as part of a study of the contribution of charitable organisations to the GDP of the United Kingdom.
The paper ends by drawing some general conclusions from this experience. 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

Couple and therapist perspectives about the use and process of reflecting team practice were analyzed using ethnographic research. A domain analysis was performed on postession interviews from both couples and therapists, and on field notes from each therapist. Seven couples and five therapists were interviewed at least twice over a 4-month period concerning their reactions to and perceptions of reflecting team practice. Six domains concerning reflecting team practice emerged from the analysis: (a)benefits of its use, (b) effects of gender, (c)recommended use, (d) contraindicated use, (e) the importance of creating spatial separateness between couple and team members, and (f) sequences of communication between the couple and team members that elicit change. The latter two domains described the process of reflecting team practice (i.e., steps in how it is used and how it is implemented). The role of ethnog rahy in reflecting team practice and in family therapy research is discussed. 相似文献

IMPROVING THE NUMERICAL TECHNIQUE FOR COMPUTING THE ACCUMULATED DISTRIBUTION OF A QUADRATIC FORM IN NORMAL VARIABLES 总被引:1,自引:0,他引:1
This paper is concerned with the technique of numerically evaluating the cumulative distribution function of a quadratic form in normal variables. The efficiency of two new truncation bounds and all existing truncation bounds are investigated. We also find that the suggestion in the literature for further splitting truncation errors might reduce computational efficiency, and the optimum splitting rate could be different in different situations. A practical solution is provided. The paper also discusses a modified secant algorithm for finding the critical value of the distribution at any given significance level. 相似文献

This paper introduces continuous‐time random processes whose spectral density is unbounded at some non‐zero frequencies. The discretized versions of these processes have asymptotic properties similar to those of discrete‐time Gegenbauer processes. The paper presents some properties of the covariance function and spectral density as well as a theory of statistical estimation of the mean and covariance function of such processes. Some directions for further generalizations of the results are indicated. 相似文献

Annual radiation doses and risks to the public living near, and traveling on, public highways, and occupational doses are calculated for highway shipments of radioactive materials under accident-free and incident-free conditions (i.e., under normal transportation conditions). The database developed by Sandia National Laboratories is used, and calculations are made using RADTRAN 4.0. This report is one of two reports estimating radiological risk associated with transportation of radioactive materials. 相似文献

An exact conditional test is developed for testing the absence of an edge in a graphical covariance selection model and is shown to be equivalent to a test based on the partial correlation coefficient. An example is given. 相似文献

This qualitative cirtical incident study examines the reactions and coping strategies of prolific family therapy scholars to difficult journal article rejections. Participants provide suggestions for ways to increase the likelihood of publication and to decrease the negative effects of journal article rejection. We discuss the implications of this investigations for the socialization of young professionals, the improvement of the journal review process, and the study of professional issues in family therapy. 相似文献
