The functional aspects of management information systems (MIS's) in human-service delivery agencies are critically examined from the viewpoint of a behavioral systems analysis model. This model distinguishes between MIS as an information-gatherer and as a system to control agency behavior and administrative decision-making. The choice of a particular MIS involves the consideration of the agency 's informational objectives, the extent to which the MIS exerts control over the decision-making process, and its cost-effectiveness. The behavior-analytic approach to MIS requires an evaluation of the way in which the system affects the behavior of agency personnel and, ultimately the clients. 相似文献

Will life expectancy in the United States rise or fall in this century? The implications of either scenario are far reaching. We contend that the rise of childhood obesity in the United States in the past three decades has been so dramatic that it will soon lead to higher than expected death rates at middle ages and a possible decline in life expectancy by midcentury. The most detrimental health and longevity effects will not be seen for decades--a phenomenon that cannot be detected by current methods used to forecast life expectancy or estimate the number of deaths currently attributable to obesity. This scenario contrasts sharply with the views of mathematical demographers who generate forecasts by relying on the assumption that the U.S. pattern of longevity will follow that of other longer lived nations and on the extrapolation of historical trends in life expectancy into the future. 相似文献

Metabolomics is based on the simultaneous analysis of multiple low-molecular-weight metabolites from a given sample. As such, metabolomics seeks the most up-to-date information about the state of interaction between an organism and its environment. The ability to use metabolomics approaches for classification and mechanistic studies may influence and augment our ability to study and address the aging process scientifically and clinically. 相似文献

Postcards to God was a creative method to allow individuals to express their spirituality. The purpose of this study was to examine the validity of this innovative method. At a skilled nursing facility in a geriatric residence, 19 older disabled workshop participants created collage and message "Postcards to God", and completed a brief survey. Postcard content and construction were coded and analyzed using qualitative methods around self-reports along two attitudinal dimensions: a) making a postcard to God; and b) level of religiousness. Spiritual and religious dimensions were related to postcard thematic content. Postcards were used for expressions of spirituality and prayer across all levels of self-reported religiousness. The Postcards project seems like useful way to facilitate spiritual expression. If validated in further study, this method may prove a useful way to promote spiritual expression in a variety of older and frail populations. 相似文献

Rates of substantiated maltreatment documented by the 1993 and 1998 Ontario Incidence Studies of Reported Child Abuse and Neglect doubled between 1993 and 1998. Although increasing public awareness and changes in investigation procedures appear to account for part of this change, the increase also reflects a significant shift in the types of maltreatment agencies are investigating and substantiating. Exposure to spousal violence has increased eightfold, and the proportion of neglect cases has more than doubled, whereas cases of sexual abuse are decreasing. The field requires a differentiated response to address the maltreatment-specific challenges underlying child welfare caseload increases in Canada. 相似文献
