Since the 1995 bombing of the Alfred R. Murrah Federal Building in Oklahoma City, academics and the general public have shown increased interest in white racial extremist and other right-wing radical groups. The interest in understanding any form of extreme intolerance requires locating the historical development of the ideas, beliefs, and actions espoused through the legislation of miscegenation in our nation's history and by extremist organizations. A chronology, used as a teaching tool, reviews the unique strands of extreme beliefs and actions and connects these understandings to the growth of racialist and extremist ideologies in the United States. This timeline provides a tool for instructors and other interested individuals in gaining an understanding of such groups by locating key developments within the laws as well as within the white racial extremist movement. Thus this chronology focuses on legislative acts and Supreme Court decisions that mirror our nation's early white racialist history. Additionally, this timeline also provides information about other social movement forces that may have affected the white racial extremist movement.  相似文献

Creativity can be understood as production of effective novelty. From the point of view of test psychology, it can be looked at either in terms of personal properties associated with novelty production or of psychological processes leading to novel results. Creativity tests can be divided along these lines into two groups: those concentrating on biographical and personal properties (creative person) and those which aim to measure creative thinking (creative process). In the case of school children, creativity tests are most useful as indicators of potential, since few children produce widely acclaimed creative products. Although a variety of creativity tests exists, their ability to measure real life creativity in a reliable way is open to doubt. This may well be because creativity involves a combination of psychological elements, some of them apparently contradictory or paradoxical, in both cognitive and noncognitive domains. Measurement of creativity probably requires new procedures that cross conventional test boundaries. Despite unresolved questions about their psychometric properties, creativity tests measure something that is not adequately covered by existing tests, especially intelligence and achievement tests, and are worth persisting with.

To examine the development of triplets, 23 sets of triplets were matched with 23 sets of twins and 23 singletons (N=138). Maternal sensitivity was observed at newborn, 3, 6, and 12 months, and infants' cognitive and symbolic skills at 1 year. Triplets received lower maternal sensitivity across infancy and exhibited poorer cognitive competencies compared with singletons and twins. The most medically compromised triplet showed the lowest regulation, received lower maternal sensitivity, and demonstrated the weakest outcomes compared with siblings. Structural modeling charted three levels of influence on cognitive outcomes: direct, indirect, and contextual. The triplet ecology provides a context for assessing the relations among infant inborn dispositions, the rearing environment, and the role of exclusive parenting in development.  相似文献

In this paper we review arguments that have been well rehearsed in the economic literature in the past twenty years and which are relevant to the present debate over student loans and the funding of the higher education sector.
The body of the paper assesses four finding proposals: (1) The Government's mortgage-type loan scheme, (2) The Barr, National Insurance repayment scheme, (3) The Graduate Tax and (4) A Loan scheme based on the individual higher education institution.
Each proposal is assessed in terms of its efficiency impact in six dimensions, (i) set up costs and flexibility, (ii) administrative costs (iii) incentives (iv) information (v) the balance of public and private involvement, and (vi) equity.
We conclude that, overall, we would not recommend any of the alternatives as unambiguously superior on all counts. Insofar as a radical approach is to be implemented we argue that a scheme based on the individual higher education institution, with repayment via the National Insurance system, is probably the best option.  相似文献

Recent widening participation policies have been subject to a number of criticisms; they focus on aspirations rather than differences in performance; they place less value on the aspirations of the ‘disadvantaged’ comparing them to a middle class norm; they subordinate what was a radical agenda to the demands of the economy and so constrain the available options to young people. Using data from young people who have taken part in Aimhigher initiatives in the South West of England and from teachers who have organised Aimhigher events, this paper will examine to what extent these features of policy are evidenced in the attitudes and aspirations of these pupils. It will argue that the data shows little evidence of pupils positioning themselves as inferior, that young people display instrumental attitudes to education, but that these attitudes relate to policy discourse and practice in complex ways.  相似文献

This article concentrates on the problems throughout the educational system, but particularly in the fields of the sciences an dengineering, created by the loss of faculty members to industry and the difficulty of attracting qualified replacements, and discusses some ideas for correcting them. Included in a discussion of incentives and rewards of a teaching career is a table showing the years of education and experience required for comparable positions in industry and teaching, as well as average salaries for these positions in a medium-sized corporation. There is also a suggestion of how a change in the tax laws would benefit the fund-raising campaigns of schools and universities.  相似文献

Thigh muscle volume is a useful determinant of functional fitness. However, anthropometric prediction of muscle content is influenced by the variability of adipose tissue accumulation. The aims of this study were to predict thigh muscle and adipose tissue volumes from anthropometry and to assess the validity of the method by examining the various components of the measurements and the assumptions involved. The 19 participants (9 men, 10 women; age 23-49 years) varied in adiposity. They all underwent magnetic resonance imaging (MRI) of the upper leg and the eight men and two women with the lowest adiposity underwent detailed anthropometry involving girths and skinfolds. Using MRI as the reference method, muscle volume was predicted from anthropometry using a circular concentric model, and the assumptions inherent in the method were tested further using the MRI data alone. Muscle volume was best predicted by anthropometry in the 10 leanest participants using a five-slice truncated cone model that overestimated the mean MRI value by 30% ( R 2 = 0.95; standard error of estimate = 288 cm 3 ; P ? 0.001). A single skinfold plus girth measurement at the mid-thigh almost matched its predictive ability, but with an increased bias. Measurements of leg circumference by means of the two techniques agreed well. The assumption of a circular cross-section was valid. In contrast, the agreement between skinfold thickness measured by caliper and superficial adipose tissue thickness by MRI was poor, contributing to the scatter of fat and lean area comparisons. An anterior skinfold thickness measurement underestimated the area of superficial adipose tissue at that level, particularly at the most proximal and distal sites. Although these limitations increase the uncertainties of muscle volume determination by anthropometry, they do not prevent its valid prediction in leaner individuals. The prediction of superficial adipose tissue was poorer.  相似文献
