Abstract An increasing interest in positive youth development has led to the creation and expansion of programs and initiatives related to youth involvement and engagement. This article focuses on the Community Development for Healthy Children initiative, which envisions making Kansas the best state in the nation in which to raise a child. The initiative includes three primary strategies: A multi-media campaign; technical assistance and support to local communities; and mini-grant opportunities. The paper provides examples of activities from across the state that promote youth involvement. Outcomes across four areas are examined, and the benefits and challenges of this initiative are also discussed. 相似文献

There has been much recent interest in supersaturated designs and their application in factor screening experiments. Supersaturated designs have mainly been constructed by using the E ( s 2 )-optimality criterion originally proposed by Booth and Cox in 1962. However, until now E ( s 2 )-optimal designs have only been established with certainty for n experimental runs when the number of factors m is a multiple of n-1 , and in adjacent cases where m = q ( n -1) + r (| r | 2, q an integer). A method of constructing E ( s 2 )-optimal designs is presented which allows a reasonably complete solution to be found for various numbers of runs n including n ,=8 12, 16, 20, 24, 32, 40, 48, 64. 相似文献

By means of an example it is shown how eigenvalues and eigenvectors of variance components models can be obtained straightforwardly when balanced data are available. Simple asymptotically efficient estimators of the variance components are presented. 相似文献

In this paper, bivariate binomial distributions generated by extreme bivariate Bernoulli distributions are obtained and studied. Representation of the bivariate binomial distribution generated by a convex combination of extreme bivariate Bernoulli distributions as a mixture of distributions in the class of bivariate binomial distribution generated by extreme bivariate Bernoulli distribution is obtained. A subfamily of bivariate binomial distributions exhibiting the property of positive and negative dependence is constructed. Some results on positive dependence notions as it relates to the bivariate binomial distribution generated by extreme bivariate Bernoulli distribution and a linear combination of such distributions are obtained. 相似文献

The case of selecting between a set of fixed models is considered. The true model is assumed to be contained in the set of proposed models and errors are taken to be normally distributed. A sequential procedure which yeilds probabilities of incorrect selections is proposed. The procedure is shown to have optimal properties and is extended to the estimated model case by a bootstrap procedure. 相似文献

A Project intended to increase client-contacting behavior on the part of 16 real-estate sales persons was described. Both contacts with prospective (initials) and with established clients (followups) were targeted for change. During a 20-week baseline, agent self-reports were used as a basis for posting weekly charts of contact behavior together with measured sales and listing performances. A conjunctive token-reinforcement procedure involving both contact behaviors was introduced during a 15 week intervention phase. For all agents as a group, a sustained increase in both behaviors was noted during this phase. Additional analyses revealed, however, that for low baseline performers, the intervention effect was only short-lived. During a subsequent three-week prewithdrawal stage, the increased behavion from the previous phase reverted nearly to baseline levels, despite the continued intervention, in response to instructions that program withdrawal was imminent. Contact behaviors further declined to below baseline levels during the following 4-week withdrawal stage when both posting and token procedures were actually discontinued. A tenninal 6 week reversal phase was marked by a nearly full recovery for all agents of asymptotic intervention levels of contact behavior under a reversed conjunctive token reinforcement schedule. Evidence indicating a correlation between changes in contact behaviors and changes in sales was presented. Also, other company benefits presumably derived from the program were described. Finally, the outcomes of this study were discussed in terms of several important validity concerns. 相似文献

在吉本芭娜娜的《厨房》和续集《满月》中,厨房不仅成为樱井美影摆脱孤独的寄托,更成为她维持生活的依靠。这种欲罢不能的厨房情结并非现代女性袁层生活的映照,而与女性深层次的传统继承有关,与女性的生理本能和心理需求有关。它是现代女性与社会妥协调和的产物。 相似文献

Several authors have proposed approximations to percentage points required for testing certain hypotheses associated with the multiplicative interaction model. Alternative approximations based on the asymptotic joint distribution of the characteristic roots of a noncentral Wishart matrix are proposed in this paper. The type I error rates of the resulting tests and the existing procedures are then compared using Monte Carlo methods. 相似文献
