Although most Jewish supplementary religious school principals have graduated from various academic training programs, there are no data about how these programs sufficiently prepare educational leaders. This study examined the essential leadership and management skills of effective Jewish religious school leaders, and assessed their preparation to undertake the key challenges of this complex job. This study also investigated the principals’ perceptions about their training and whether they experienced a knowledge gap as school leaders. The respondents felt unprepared to conduct essential tasks—such as working with lay leaders, managing human resources, and planning budgets—after completing their training programs. 相似文献

Four experiments investigated the stimulus properties of female mice that influence ultrasound production by adult males. Female urine alone was less effective in evoking ultrasounds than was the female in male-female pairs. Visual cues were not necessary, since there was no difference in the incidence or latency of ultrasounds from male-female pairs when tested in light and dark conditions. A presently unspecified chemical cue produced by females, whose effectiveness is mediated by olfaction, was sufficient to evoke ultrasounds from male mice. The role of this chemical cue in a multimodal sequential communicative chain is discussed. 相似文献

46 3-month-old infants were presented with geometric stimuli moving laterally at two different velocities (34.8 degrees/sec; 103.3 degrees/sec). The results were interpreted as evidence that 3-month-old infants could discriminate between geometric forms moving at velocities that, according to previous findings, might interfere with shape discrimination. The findings are discussed in relation to the possible interactive effect of type and velocity of movement on geometric form discrimination. 相似文献

Publishing flourishes best in a democratic society. Technological changes alter the relationship of forces so that opportunities
for publishing expand. A broader range of information channels, for example, increases choice and makes authoritarian rule
more difficult. Publishing also enhances democracy when decisions are made on the basis of merit rather than top-down legislation.
Research should reflect awareness of the interaction of publishing and politics. Such areas as the relationship between public
and private sectors, the impact of internationalization, non-U.S. ownership of information, mergers and acquisitions, and
conflict between the First Amendment and copyright law, are examples of areas in which democratic outcomes are critical. Decision
making in publishing would benefit from heightened awareness of the political consequences of publishers’ activities.

A correlation structure modeling method for comparison of mediated effects is outlined. The procedure permits point and interval estimation of differences in mediator effects, and is useful with models postulating 1 or more predictor, intervening, or response variables that may also be latent constructs. The approach allows scale-free evaluation of differences in effects of any explanatory upon criterion variables transmitted via studied mediators, and is applied on data from a study of older adults with recent vision loss. 相似文献
