De minimis and equity in risk

Indices and orderings are developed for evaluating alternative strategies in the management of risk. They reflect the goals of reducing individual and collective risks, of increasing equity, and of assigning priority to the reduction and to the equity of high risks. Individual risk is defined as the (random or non-random) level of exposure to a danger. In particular the role of a lower negligibility level is investigated. A class of indices is proposed which involves two parameters, a negligibility level and a parameter of inequality aversion, and several interpretations of the indices are discussed. We provide a set of eight axioms which are necessary and sufficient for this class of indices, and we present an approach to deal with partial information on the parameters.     

中国古代诗歌艺术之根本精神──“无我相”

儒、释、道三家哲学的共同特正是“无我相”;中国古典诗歌艺术的根本精神也是“无我相”,代表儒释道三家精神的诗人屈原、王维和陶渊明三派诗歌,以艺术手段显现至高无上之境──“物我皆忘”,“物我一体”、在此境界之中,诗歌作为艺术家心灵的外化,绝不是中纯的语言文字对情感的渲泄,而是生命中修炼境界的极致,通达这种“无我”的人格境界和艺术精神,正是中国诗歌艺术的根本精神,     

Comparative probability for conditional events: A new look through coherence

We study, from the standpoint of coherence, comparative probabilities on an arbitrary familyE of conditional events. Given a binary relation ·, coherence conditions on · are related to de Finetti's coherent betting system: we consider their connections to the usual properties of comparative probability and to the possibility of numerical representations of ·. In this context, the numerical reference frame is that of de Finetti's coherent subjective conditional probability, which is not introduced (as in Kolmogoroff's approach) through a ratio between probability measures.Another relevant feature of our approach is that the family & need not have any particular algebraic structure, so that the ordering can be initially given for a few conditional events of interest and then possibly extended by a step-by-step procedure, preserving coherence.     

Homework and domestic work

This study assesses two competing theories about the extent to which homework—paid work in the home—helps integrate work and domestic roles for men and women. Contrasting male and female homeworkers with their counterparts working outside the home, it supports some aspects of both the resource and role overload theories, but predominantly the role overload perspective. Homeworkers, especially in the working class, experience less interference between job and family life, but perform more housework and child care. They have no more leisure time nor greater marital satisfaction than those working outside the home, but receive more family assistance with their paid jobs, suggesting that they combine tasks from their first and second shifts. Working at home does not break down gender roles in domestic life. Despite time saved from commuting, male homeworkers perform no more housework than comparable men working outside the home. Thus, the gender division of unpaid household labor is not simply a matter of resources or spatial logistics.An earlier version was presented at the meetings of the Eastern Sociological Society, Providence, Rhode Island, April 1991.     

Factors associated with expectation of household's future financial condition

Path analysis is used to examine the causal relationships among selected objective and subjective factors associated with a household's expectation of future financial condition. Results indicate that respondents who perceive the effect of changes in the external environment on their own household's financial condition as positive are younger, have higher net worth, perceive more internal control over their situation, and report that most of the changes in the external environment are positive. Respondents who are younger, have higher income, perceive more internal control over their situation, and believe the effect of changes in the external environment on their household's financial condition are positive are more likely to be optimistic about their financial future. It is important that educators and financial advisors recognize the significant role perception of being in control plays in determining expectations of future financial condition.Journal Paper No. J-15256 of the Iowa Agriculture and Home Economics Experiment Station, Project No. 2809.

Correlates of honor ratings in a clinical clerkship employing a faculty forum evaluation system

5he purpose of this study was to determine whether or not suspected variables affected a surgery clerk's chances of being awarded an honor rating. Findings indicated a significant relationship between a student receiving an honor rating and his or her preceptor's predetermined level of student advocacy, the number of completed patient interview and physical examination write-ups, and final examination scores. There was no significant relationship found between honor ratings and the preceptor's status, the sequence in which the student was discussed or the length of time spent discussing the student at the final evaluation meeting, or the number of clinical faculty present at the meeting. These results lend support to the faculty forum evaluation approach, but suggest a need for further scrutiny of some influencing variables to ensure all students are fairly considered and honor ratings judiciously awarded.     

Physician perceptions of medical malpractice and defensive medicine

Using judgments obtained in interviews with 33 Massachusetts physicians, the annual statewide volume of expenditures incurred for defensive medical reasons in 1982 was estimated to be $1.0 billion, 12% of all medical care expenditures. Estimates for the nation were $37 billion, 14% of expenditures. Nationally, 180,000 cesarean deliveries were thought to be performed for defensive motives. In their own institutions, respondents judged 43% of all skull x-rays following injury to be medically justified, 30% to be defensive medicine, 16% to be placebos, and 11% to be physician misjudgments. In considering the economic and noneconomic costs of medical malpractice procedures, the dollar costs of insurance were considered most serious, followed closely by defensive medicine, unfairness, and poorer relations with patients. Thirty-two percent of the responsibility for the negative aspects of malpractice processes was assigned to lawyers, 21% to physicians, 18% to legislatures and courts, 16% to patients, and 13% to insurance companies.     

Mental health program evaluation: Where you start?

Seduced by the elegance, sophistication and jargon characteristic of new developments in applied research, practicing evaluators are in danger of becoming distracted from achievement of their evaluative goal: that of providing timely, reliable and useful data to program management to facilitate rational data-based decision-making. To avoid such seduction, the author advocates adaptation of simple, inexpensive and efficient evaluative methods tailored to organizational needs and presentation of findings in language readily understood by constituent groups. Likewise, insistance by evaluators upon maintenance of a strict role boundary — that is, limiting role functioning exclusively to those tasks considered evaluation — may be dysfunctional. Rather than detract from accomplishment of his goals, the author maintains that such participation allows development of skills, insights and staff relationships which enhance the evaluator's effective functioning within the organizational context and contribute to organizational acceptance and use of his evaluative results.     

Network analysis in evaluation: some words of caution

Network analysis, a methodology derived from general systems' theory, can be utilized as a community mental health administrative-evaluation procedure. Evaluation parameters derived from analysis of patient data as they “flow” through a network of agency services, provide measures of systemic functioning. These parameters include “longest paths” and various ratio relationships as evaluation measures of service delivery. The limitations of network analysis are examined by means of conceptual analyses, and phenomena that emerged from research experience. The necessity for both quantitative and qualitative data to ensure a meaningful evaluation of mental health services is explained. Conclusions about the value of the network analysis approach are considered.     

Artifact in client satisfaction assessment: experience in community mental health settings

Artifact in client satisfaction assessment is discussed and the results of a study of three factors thought to mediate client satisfaction ratings; (a) general life satisfaction, (b) mode of administration, and (c) psychological symptomatology, are reported. A standard client satisfaction questionnaire (CSQ) was modified to yield parallel forms and was administered orally and in writing to 92 clients in two mental health day treatment programs. Satisfaction ratings obtained from these clients were quite similar to out-patient ratings obtained in previous studies conducted in this setting and using the same measures. Oral administration of the CSQ produced 10% higher satisfaction ratings than written administration (p less than .05) and less missing data (p less than .01). Satisfaction ratings were also obtained using a simple graphic instrument. Graphic ratings were comparable to CSQ ratings. Satisfaction with life in general and level of psychiatric symptoms together accounted for 25% of CSQ variance. The implication of these findings for future client satisfaction research is discussed.
