Christine Hunt Ian Shochet Robert King 《Australian and New Zealand Journal of Family Therapy》2005,26(1):10-20
The therapeutic letter has a long history, with roots in psychoanalytic work and continuing application in family therapy. The advent of e‐mail has allowed another form for therapeutic written communication which, while incorporating the benefits of therapeutic letters, adds to these. It has also opened up some potential risks. This article incorporates a brief review of the literature covering therapeutic written communication and offers a case example where e‐mail was used as an adjunct in face‐to‐face therapy with a client who experienced attachment difficulties. This therapy was informed by systemic and psychoanalytic traditions. The authors explore a variety of technical matters including the timing and crafting of e‐mail responses, the integration of written communication with face‐to‐face therapy, impact on the therapeutic relationship and management of crisis. Ethical issues such as confidentiality and duty of care are also considered. 相似文献

Public administration finds itself in an era of government byperformance management, which is reflected in the widespreadassumption that management is a key determinant of performance,and that it is reasonable to expect managers to measurably improveorganizational effectiveness. This article joins a growing literaturein seeking to conceptualize and empirically test how externalenvironmental influences and internal management factors combineto create performance, relying on data from the 20022003National Administrative Studies Project (NASP-II) survey ofstate government health and human services officials. We categorizemanagerial efforts to facilitate organizational performanceas determined either through their interactions with the organizationalenvironment, or through employing workable levers to changeinternal organizational culture, structure, and technology.Among the external environmental variables we find that thesupport of elected officials and the influence of the publicand media have a positive impact on effectiveness. Among internalmanagement choices, the ability to create a developmental organizationalculture, establish a focus on results through goal clarity,and decentralize decision-making authority are all positivelyassociated with organizational effectiveness. 相似文献

Summary. In longitudinal studies, missingness of data is often an unavoidable problem. Estimators from the linear mixed effects model assume that missing data are missing at random. However, estimators are biased when this assumption is not met. In the paper, theoretical results for the asymptotic bias are established under non-ignorable drop-out, drop-in and other missing data patterns. The asymptotic bias is large when the drop-out subjects have only one or no observation, especially for slope-related parameters of the linear mixed effects model. In the drop-in case, intercept-related parameter estimators show substantial asymptotic bias when subjects enter late in the study. Eight other missing data patterns are considered and these produce asymptotic biases of a variety of magnitudes. 相似文献

Robert van Krieken 《The Sociological review》1991,39(1):1-25
The concept ‘social control’ has been criticised from a variety of quarters in recent years, particularly by historians and historical sociologists. However, it remains in common usage in sociological studies of welfare, deviance and social control. This paper shows, first, how this reliance on the concept of social control is rooted in a wider-ranging argument in social and political theory concerning the liberal-democratic fusion between the state and civil society, and that the lack of resolution of this argument is the foundation of the persistence of the concept social control in other areas of social inquiry, despite its repeated ‘falsification’. Second, the paper highlights the main arguments against the use of ‘social control’ in explaining social order, in particular the misunderstanding of class, culture and power which its use encourages, and the paper will conclude with a discussion of alternative ways of conceptualising the operation of power in contemporary societies. 相似文献
