This paper reports an empirical investigation of the effects of three pictorial forms of problem representation on conformance with the Reduction of Compound Alternatives Principle of expected utility theory. The most common form of representation, written problem statements, was compared with three pictorial representations: tubes containing one hundred labeled balls, decision matrices with each column proportional in size to the probability of the corresponding event, and bar graphs. The tubes representation led to fewer violations of the Principle. In addition, when subjects were trained to construct proportional matrices from written problem statements, they exhibited fewer violations than those who received the same problems already formatted in proportional matrices. The results reported here should contribute to the development of a theory of the way people frame decision problems.  相似文献

The idea of standardizing concepts in sociology is not new, but we have made little progress, despite the early hopes of such theorists as Durkheim and Weber. This article refutes the arguments of some who contend that we do not need standard concepts, we cannot make standard concepts, social phenomena are too complex and changeful, sociologists are too individualistic and sociological concepts are too context-dependent. The author proposes that the American Sociological Association appoint a Committee on Basic Sociological Concepts to investigate and recommend the official adoption of a basic conceptual language in American sociology. This paper is excerpted from a longer discussion first presented to a session on metatheory at the 1990 meetings of the American Sociological Association, and forthcoming in a collection of papers from that session.  相似文献

As soon as men and women … acquire the habit of weighing the individual advantages and disadvantages of any prospective course of action … they cannot fail to become aware of the heavy personal sacrifices that family ties and especially parenthood entail under modern conditions.

The traumatized children of violent marriages   总被引:2,自引:0,他引:2  
Over three million children, it is estimated, witness parental violence annually. The clinical effects upon many children are characteristic of trauma, with dissociation and defensive protections against recall and resolution that can be pathological. This article presents the case for this assessment and describes the successful treatment of an eight-year-old-boy.  相似文献

Results from analysis of 227,771 discharge abstracts from 68 short-term, acute-care hospitals and from interviews with a stratified random selection of 24 of the 68 chief executives of these hospitals demonstrate that institutions perceive implementation of DRGs as fiscally constraining, especially in light of other resource-constraining conditions (an increase in unemployment resulting in fewer people with hospitalization insurance, in addition to severe cuts in Medicaid rolls and budget). Hospitals responded to DRGs by decreasing the use of affected resources or services available to the hospitalized Medicare patient. In order to survive a more economically stringent marketplace, hospitals no longer protected the traditional core within the Medicare inpatient market. They opted instead to change practices and products at the unregulated margins of the DRG system.  相似文献

It is widely believed that monetary aggregates have failed to predict economic performance over 1983-87. This paper observes that the traditional definition of money (M1 lessother checkable deposits, or M1A) shows no evidence of structural change, and yields lower prediction errors for both real GNP and inflation over 1983-87Q2 than the errors obtained using M1 or M2. If there is a mystery, it is not why MIA has done so well, but why economists abandoned it for M1 or what was once called M1B (currency, demand deposits, and other checkable deposits).  相似文献

EBV has both physiological and psychological implications. Few medical/nursing interventions are available to alleviate the physical stressors and fatigue. The primary nursing intervention, therefore, becomes one of providing emotional support and psychosocial interventions. Providing measures to ensure adequate sleep will assist the patient in more positive feelings about self. Although causation and diagnosis of this syndrome may be debated in the medical literature, the nursing role is to provide support and guidance for these patients. Longitudinal studies could be done to facilitate the understanding of the long-term effects of EBV and the outcome measures of mental health interventions.  相似文献
