Numerous studies have identified deterrents to participation in adult education among adult learners, mainly in formal settings. The purpose of this study was to examine institutional deterrents to participation as identified among African Americans who are members of religious institutions, specifically African American Christian churches. Institutional deterrents were classified into six different rubrics. Results from the study suggest African American Christian churches should closely examine their policies and procedures for developing and marketing their educational programs and developing or enhancing teacher preparation techniques. 相似文献

Around the end of the 1920s, Vygotsky introduced his integrative framework for psycho-logical research to the Soviet Union. This framework was not abandoned and forgotten until its rediscovery in Russia and America in the 1950s, as some claim. In fact, even after his untimely death in 1934, Vygotsky remained the spiritual leader of a group of his for-mer students and collaborators, who became known as the Kharkov School. This paper reconstructs the early intellectual history of Vygotskian psychology, as it emerged, around the time of Vygotsky's death, in the research program of the Kharkov School. 相似文献

This paper presents a practical implementation of multicriteria methodologies based on the UTA model by Jacquet‐Lagrèze and Siskos and Quasi‐UTA model by Beuthe and Scannella, which are specified with a non‐linear, but piecewise linear, additive utility function. In contrast with the general UTA model, the Quasi‐UTA specification structures the partial utilities as recursive exponential functions of only one curvature parameter. This allows for a reduction of the quantity of information necessary to build the utility function. The software MUSTARD implements different variants of these models. Firstly, it offers the basic deterministic UTA model of disaggregation, but also its first programmed stochastic version. In both cases, the software proceeds stepwise and interactively helping the decision maker to formulate the problem and state preferences between projects; in the stochastic case, the decision maker is even helped to build the criteria distributions. The Quasi‐UTA specification can be introduced in this disaggregation model. Secondly, the software offers an aggregation model whereby the Quasi‐UTA partial utility functions are built separately through specific questioning processes. The questions relating to deterministic criteria are of the ‘direct rating type’, while those of the stochastic criteria are either of the ‘variable probability’ or the ‘variable outcome’ type. The criteria weights can be assessed by the ‘swing weight’ method or by a UTA‐II side‐program. As an example as well as a test of the Quasi‐UTA aggregation approach, the paper presents its application to a real problem of selecting road investment projects in Belgium. Several experts and civil servants were interviewed, and their individual utility functions derived. The projects are ranked according to their rate of return, which is computed on the basis of the projects certain equivalent money value. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

The gap between male and female suicide rates in India is relatively small. However, society's views on female and male motives are quite different. In order to investigate the perceptions of male and female suicide, we interviewed a focus group of university professors as well as police inspectors, crime reporters, and hospital nurses in Bangalore. We also obtained four narratives of suicide. Women tended to be blamed for their own or their husband's suicide, although they were also viewed more often as victims of life adversities than men. A historical review illustrates that both men and women have been associated with culturally sanctioned suicides. One known form is sati, and we discuss the recent case of sari-murder of Roop Kanwar in 1987. The social sciences and the media also pay a lot of attention to the typical female suicides, symbolizing their role as martyrs of society, which seems to compensate for attribution of blame. 相似文献

Rates of suicide by jumping show large regional differences. Barriers on bridges may prevent suicides but also may lead to a substitution of jumping site or method. The aim of our study was to compare suicide data from regions with and without suicide bridges and to estimate the effects on method and site substitution if bridges were to be secured. In a national survey, suicide data for the years 1990 to 2003 were collected. Regions with high rates of bridge suicides were identified and compared with regions with low rates, and the analysis revealed that only about one third of the individuals would be expected to jump from buildings or other structures if no bridge was available. The results suggest no method substitution for women. For men, a trend of a substituting jumping by overdosing in regions without suicide bridges was found. We conclude that restricted access to suicide bridges will not automatically lead suicidal individuals to choose another jumping site or suicide method. The results support the notion that securing bridges may save lives. 相似文献

Children, aged 5 and 8 years, and adults were tested in a bisection task with a sequence of stimuli in which time and number co-varied. In a counting and a non-counting condition, they were instructed either to process the duration of this sequence while ignoring the number of stimuli (temporal bisection), or to process the number of stimuli while ignoring the duration (numerical bisection). In the temporal bisection task, number interfered with the 5-year-olds' temporal performance, indicating that young children did not process time and number independently in a sequence of stimuli when they had to attend to duration. However, number interference decreased both with age and counting strategy. In contrast, in the numerical bisection task, duration did not interfere with numerical discrimination for any age group. 相似文献

In this paper, we provide a detailed critical review of current approaches to ecthesis in Aristotle’s Prior Analytics, with a view to motivate a new approach, which builds upon previous work by Marion & Rückert (2016) on the dictum de omni. This approach sets Aristotle’s work within the context of dialectic and uses Lorenzen’s dialogical logic, hereby reframed with use of Martin-Löf's constructive type theory as ‘immanent reasoning’. We then provide rules of syllogistic for the latter, and provide proofs of e-conversion, Darapti and Bocardo and e-subalternation, while showing how close to Aristotle’s text these proofs remain. 相似文献
