Bulgaria, like other East European nations since the collapse of communism, has moved rapidly to form private, self-directed
non-profit and voluntary organisations. Like those nations too, Bulgaria faces a number of challenges in its pursuit of forming
a strong non-profit sector. Chief among those challenges are establishing a sound legal foundation, defining the social purposes
and functions of the non-profit sector, and establishing the legitimacy of these organisations in the minds of the Bulgarian
people. These three challenges are analysed in the essay, following an overview of the current make-up and characteristics
of the emerging non-profit sector. 相似文献

To ascertain whether actual and perceived emotional sending are distinct constructs, the present study investigated the relationship between subjects' ability to facially express six basic emotions and their perceived success at expressing these emotions. Sixty-eight subjects completed a number of standardized personality scales and were videotaped while attempting to portray six basic emotions. Immediately following the videotaping subjects were asked to rate their perceived success in the emotional-sending task. Observers then judged the emotional-sending videotapes to determine subjects' actual sending abilities. A confirmatory factor analytic model indicated that actual and perceived emotional-sending were distinct factors. Zero-order correlations between the traditional personality measures and the actual and perceived sending factors also supported this distinction. These findings have important implications for the construction of standardized measures of individual differences in nonverbal communication skills.This research was supported by a UCR intramural research grant and a UCR NIH Biomedical Support Equipment grant. The authors would like to thank Richard Lippa and Louise Prince. 相似文献

Children in foster care face poverty, family dysfunction, neglect, and abuse, with high rates of chronic health, emotional, and developmental problems. This study compared the overall health status of a group of children entering foster care with a group of Medicaid-eligible children living with their parents, matched for age and gender. It identified significantly more health and developmental problems in children in foster care than in the comparison group. Possible contributors to the higher percentage of problems among foster care children may be that the foster children have more problems related to the underlying risk factors resulting in placement, or that the foster care physicians conducted a more comprehensive assessment or had lower clinical thresholds. Further research is necessary to identify and treat the problems of this high-risk group. 相似文献

The cartoon character Pogo, uttering his now famous line, "We have met the enemy and it is us," might well have been referring to the dilemmas that we face today in American health care. A major source of our current difficulties in solving these admittedly complex problems lies in our way of thinking about, or conceptualizing, health care and health care delivery. We are caught in an old paradigm that is simply not adequate for dealing with the health care delivery problems of the '90s, not to mention those of the 21st Century. 相似文献

The author is an investment analyst whose area of specialization is financial shares, especially in banking. The prime responsibility of the investment analyst is to the investment institutions. However, the information available to the analyst is no more than that available to shareholders in the institution being monitored. The expertise of the analyst is in seeking out the information and interpreting it for the client. There has been a considerable improvement in investor relations in the U.K. in the past few years. The author suggests that more information could be provided by the U.K. Clearing Banks—information which is readily available within the banks—which would enable the investment analyst to make important comparisons from data which is not at present available to him. 相似文献

Randomly censored covariates arise frequently in epidemiologic studies. The most commonly used methods, including complete case and single imputation or substitution, suffer from inefficiency and bias. They make strong parametric assumptions or they consider limit of detection censoring only. We employ multiple imputation, in conjunction with semi-parametric modeling of the censored covariate, to overcome these shortcomings and to facilitate robust estimation. We develop a multiple imputation approach for randomly censored covariates within the framework of a logistic regression model. We use the non-parametric estimate of the covariate distribution or the semi-parametric Cox model estimate in the presence of additional covariates in the model. We evaluate this procedure in simulations, and compare its operating characteristics to those from the complete case analysis and a survival regression approach. We apply the procedures to an Alzheimer's study of the association between amyloid positivity and maternal age of onset of dementia. Multiple imputation achieves lower standard errors and higher power than the complete case approach under heavy and moderate censoring and is comparable under light censoring. The survival regression approach achieves the highest power among all procedures, but does not produce interpretable estimates of association. Multiple imputation offers a favorable alternative to complete case analysis and ad hoc substitution methods in the presence of randomly censored covariates within the framework of logistic regression. 相似文献

The current investigation examined performance on two laboratory-based gambling tasks, the Georgia Gambling Task (GGT; Goodie,
2003. The effects of control on betting: Paradoxical betting on items of high confidence with low value. Journal of Experimental Psychology: Learning, Memory, and Cognition, 29, 598–610) and the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994. Insensitivity to future consequences
following damage to human prefrontal cortex. Cognition, 50, 7–15), as well as self-reported markers of gambling pathology using the Diagnostic Interview for Gambling Severity (DIGS;
Winters, Specker, & Stinchfield, 2002. The downside: Problem and pathological gambling (pp. 143–148). Reno, NV: University of Nevada, Reno) among a sample of undergraduate students who are frequent card players.
Two hundred twenty-one participants (55 female and 166 male; mean age 19.21 years) who self-classified as playing cards at
least once per month completed these measures. Performance on GGT and IGT systematically related to gambling-related pathology
in several ways. Overconfidence and bet acceptance on the GGT, and myopic focus on reward on the IGT, predicted gambling related
pathology. GGT and IGT performance correlated with each other, but both contributed independently to predicting gambling pathology.
Card playing frequency predicted gambling pathology but not GGT or IGT performance. Discussion focuses on the role of biases
of judgment and risky decision making in pathological gambling. 相似文献
