The Astor Transitions Program (ATP) was developed to assist youth with emotional and behavioral disorders moving into a new educational environment where the services would often be less integrated. A research/evaluation consultant was hired to conduct a program evaluation of the ATP. The study sample consists of the charts of 150 consecutive students admitted to ATP between April 2010 and March 2013. The following hypothesis was tested: the ATP service in terms of caseworkers’ contacts will be associated with better clinical and educational outcomes. The major findings were the impact of caseworker contacts on clinical outcomes was indirect and greatest on type of placement; caseworker contacts had no effect on school attendance, yet ATP students were present about 85% of the time; and casework activity increased for chronic cases in placement but decreased after hospitalization. Recommendations were made to program staff on how to improve ATP services.  相似文献

Alcohol use by 1190 fourth, fifth and sixth grade students was assessed in a survey of four rural New Hampshire school districts. Half the students surveyed (596) drank, but not regularly; 5 percent (59) were regular drinkers, and an additional 2 percent (19) were regular drinkers and had been drunk at least once. Reported alcohol use increased with both grade and age, and males drank more than females. The child's attitude toward drinking, perceived family attitudes towards drinking, the number of drinking friends, and self-perceived wrongdoing by the child were four factors strongly related to alcohol use. Increased alcohol use was also associated with experimental and current use of cigarettes, marijuana, and smokeless tobacco.  相似文献

Many of the contemporary models used to describe the behavior of the mineral industries assume a competitive market i.e. one in which market price is equal to marginal production cost. One such recent model of the worldwide copper industry is the MIDAS-II model developed for the Bureau of Mines [3, 4]. This model is used to project production and prices up through the year 2000. The purpose of this paper is to demonstrate the importance of the assumed market structure in the construction of these forecasts. If the market structure of the US copper industry is assumed to be comprised of a few large firms (an oligopoly), then forecasts based upon exactly the same data base differ significantly from the competitive market assumption.  相似文献

In management theory a gap seems to exist between consumer buying behaviour and the economic life cycles of products. This gap is the subject of this paper using product value matrices (PVMs). Brought together in this paper are some well-known theories dealing with consumer behaviour, buying behaviour and product life cycles (PLCs), in a manner that provides useful information to all firms. Too often it is found that these theories are elegant in isolation, but provide little help in focusing a company's efforts. Consumer behaviour has been researched for many decades, as has product life cycles, but the link between consumer buying behaviour and economic life cycles of products is mystical, with most chief executive officers (CEOs) believing it occurs like magic. The paper initially develops frameworks describing the economic life cycles of products and consumer buying behaviour. The paper then links the frameworks with the product value matrix and illustrates how they can be used in focusing a firm's efforts.  相似文献

This article discusses earnings differentials among skilled Western, Arab and Asian migrants, who constitute most of the private sector labour force in Gulf Cooperation Council (GCC) countries, during the period 2012–14. Using two standard decomposition methodologies, it investigates the view that Westerners are paid premium rates due to the unobserved perceptions of private employers. The results indicate that while one‐third to three‐quarters of real hourly earnings differentials are attributable to differing observed levels of productivity‐related characteristics, the remainder are due to the incorporation of higher opportunity costs for Westerners into the bargaining process. The potential effect of unobserved perceptions is found to be irrelevant to observed earnings differentials.  相似文献

This paper describes research undertaken using futures research methods to construct a data bank on the future business environment. It is called The Business Trends Library. It is often said that it is not possible to forecast business futures, so planning should be adapted so that we can drive blind into the future. The author disagrees with this school of thought. Most studies of business futures appear to be too narrowly based and not systematic enough. When interactions from all relevant areas can be taken into account, it is possible to narrow the uncertainty considerably about future events, and be much more specific about what will happen. Examples are shown to illustrate this.  相似文献
