Content (item) bias on the Mental Processing Scales and the Achievement Scale of the Kaufman Assessment Battery for Children (K-ABC) was investigated with 100 Mexican American and 100 White fifth- and sixth-grade boys and girls. All children were English-speaking and from similar socioeconomic status (SES) backgrounds. An item-group (partial correlation) method that controlled for age, sex, and ability was used to examine bias. On the Mental Processing Scales, 17 (14%) of 120 items were found to be biased—the strong majority against the Mexican American children. On the Achievement Scale, it was observed that 58 (63%) of 92 K-ABC items were biased—all against the Mexican American sample. This latter finding is discussed in the context of possible differences in learning opportunities (language based, SES based, and school segregation) experienced by the two ethnic groups. 相似文献

The assignment offered to the author in 1972 (under the auspices of the UK Ministry for Overseas Development 1972—73) was stated quite simply — “adapt the concept and philosophy of UK sandwich/co-op courses to fit into the structure and organisation of a university in Venezuela.” The work was to be based on the proposals contained in a feasibility study (under the auspices of Unesco February to April 1970) undertaken by him in 1970. The location for the courses was to be Universidad Simon Bolivar, which is situated on 380 hectares in the Valle de Sartenejas some 15 km south of the centre of Caracas, the capital. 相似文献

Purpose:
A systematic literature review was conducted to synthesize what is known about informationists, highlight program models, and suggest areas for future research.Methods:
Articles retrieved through database searching were reviewed for relevance. Informationist case reports were identified and coded according to an attributes checklist. Data from other retained publications were synthesized under broad themes. The few research studies found were reviewed for level of evidence.Results:
Of 113 papers reviewed, the study identified 7 classic and 8 emerging informationist programs. Two major models are apparent, clinical and research, with priorities differing according to program maturity. The literature synthesis also brought together current thinking about informationist qualifications; practice roles; setting characteristics; education and training; organizational, programmatic, and service provider success factors; and challenges and barriers. Program outcomes to date are reported, and future research topics suggested. Specific findings will assist informationist program planners.Conclusions:
While the informationist concept remains in the early adopter stage, it appears that domain knowledge, continuous learning, and embedding (working in context) are essential to success. The need for librarians to transition to greater specialization and libraries to emphasize customized service was underscored. A research agenda focused on information management, dissemination, behaviors, and economics is proposed.Highlights
- After years of emphasizing the generalist librarian, health sciences librarians must become more specialized, paralleling the health care environment in which they work.
- An embedded informationist is more likely to achieve credibility, acceptance, and sustainability than an impersonal information service provided at a distance.
- Subject expertise is essential for the informationist.
- Model informationist programs with the greatest stability are library funded.
- Because informationist programs are inherently targeted to small groups, multisite studies are necessary to achieve robust evaluation.
Implications
- A library starting an informationist program should review existing models, identify local needs, set program objectives, and then select the most appropriate approaches for its users.
- Programmatic emphasis should be placed on both technical and service excellence.
- Organizational commitment is needed for knowledge integration into practice and for the informationists'' lifelong learning.

Religiosity,the headscarf,and education in Turkey: an analysis of 1988 data and current implications
Previous research highlights the continuing relevance of family culture in explaining educational inequalities in Turkey, especially patriarchal beliefs and practices that discourage investment in the education of girls. We extend that research by introducing two much‐debated, but empirically untested, aspects of family culture – parental religiosity and headscarf preferences. An analysis of a nationally representative sample of 15–19 year olds in 1988 shows that while religiosity had no significant effect on educational attainment, children who lived in families whose fathers expected them to wear a headscarf in public had lower educational attainment, especially girls. The large negative headscarf effect suggests that the government ban on headscarves in schools may be an obstacle to eliminating gender inequality in education. The results are discussed in light of recent trends in Turkish society. 相似文献

A method is described for isolating factors which influence the ability of a reader to comprehend the message of an illustration. It is suggested that a flow chart or model can be constructed from these factors to highlight potential problem stages in an author's design of an illustration. The model is constructed using data from comprehension trials and critical commentary with readers, incorporating a set of factors which would be of use to prospective authors of illustrations. The procedure is largely non-experimental and intended to demonstrate a procedure for model building.The research presented here formed part of his Doctor of Philosophy program at Griffith University, Brisbane, which was awarded in 1986. 相似文献

To begin an investigation of the cellular processes that underlie long-term memory in the nematodeCaenorhabditis elegans, it is first necessary to determine thatC. elegans is capable of retention over 24 h, and to investigate the factors that may influence the expression of long-term memory. In the present study, the effects of stimuli number, interstimulus interval (ISI), and training procedure on long-term retention of habituation were tested inC. elegans. At a long (60-sec) ISI, distributed training sessions produced long-term habituation retained for 24 h, whereas massed training sessions or training with few stimuli did not. When training was performed at a short (10-sec) ISI, long-term habituation was not detectable with testing at either a 10- or a 60-sec ISI. The long-term habituation observed after distributed training sessions at a 60-sec ISI was consistently expressed when the training procedures were varied. Thus it is clear thatC. elegans can reliably express long-term retention for distributed training sessions at a 60-sec ISI, making the system a candidate for further investigations into the cellular processes supporting memory. 相似文献

Previous planar models of the downswing in golf have suggested that upper limb segments (left shoulder girdle and left arm) move in a consistent fixed plane and that the clubhead also moves only in this plane. This study sought to examine these assumptions. Three-dimensional kinematic analysis of seven right-handed golfers of various abilities (handicap 0?–?15) was used to define a plane (named the left-arm plane) containing the 7th cervical vertebra, left shoulder and left wrist. We found that the angles of this plane to the reference horizontal z axis and target line axis (parallel to the reference x axis) were not consistent. The angle to the horizontal z axis varied from a mean of 133° (s = 1°) at the start of the downswing to 102° (s = 4°) at impact, suggesting a “steepening” of the left-arm plane. The angle of the plane to the target line changed from ??9° (s = 16°) to 5° (s = 15°) during the same period, showing anticlockwise (from above) rotation, although there was large inter-individual variation. The distance of the clubhead from the left-arm plane was 0.019?m (s = 0.280?m) at the start at the downswing and 0.291?m (s = 0.077?m) at impact, showing that the clubhead did not lie in the same plane as the body segments. We conclude that the left arm and shoulder girdle do not move in a consistent plane throughout the downswing, and that the clubhead does not move in this plane. Previous models of the downswing in golf may therefore be incorrect, and more complex (but realistic) simulations should be performed. 相似文献
