The authors, as leaders in a public child welfare system, have teamed together and reached out to their private sector partners in a large, rural county in western Colorado. This effort was part of a comprehensive, communitywide effort to redesign and fundamentally improve the entire child welfare service delivery system. Across the country in many areas where collaboration and integration have been the focus, we often hear voices in the private and public sector declaring the importance of integration. Why, then, does it not happen as a general course of action? The authors believe the answer lies in leadership, both public and private. They hold the Mesa County model up as witness to that fact. 相似文献

In the second part of this paper the author traces the processes by which it is possible to learn rule conforming behaviours without necessarily being able to formulate the rule or see any point in the rule; the rule is followed blindly. In following a rule blindly a person may nevertheless be engaged in a practice which has a systemic function; he argues that when we positively connote symptomatic behaviours in the process of making paradoxical systemic interventions, we should avoid any suggestion that the family members are acting deliberately with the goal of “helping” in mind. 相似文献

The effectiveness of the Relationship Enhancement (RE) program (Guerney, 1987a) in increasing functional and basic levels of differentiation of self (Bowen, 1987a) was examined. Participants were 20 married couples who received training in relationship enhancement skills over six 2 1/2-hour sessions. Measures of differentiation of self, quality of relationship, and anxiety were obtained before and after training and at follow-up. The data show that significant increases in the functional and basic levels of differentiation of self occurred, a significant increase in the quality of relationship occurred, and significant negative correlations were found between differentiation of self and anxiety. 相似文献

Little is known about effective eHealth recruitment methods. This paper presents recruitment challenges associated with enrolling African-American girls aged 8–10 years in an eHealth obesity prevention program, their effect on the recruitment plan, and potential implications for eHealth research.Although the initial recruitment strategy was literature-informed, it failed to enroll the desired number of girls within a reasonable time period. Therefore, the recruitment strategy was reformulated to incorporate principles of social marketing and traditional marketing techniques. The resulting plan included both targeted, highly specific strategies (e.g., selected churches), and more broad-based approaches (e.g., media exposure, mass mailings, radio advertisements).The revised plan enabled recruitment goals to be attained. Media appeared to be particularly effective at reaching the intended audience. Future research should identify the most effective recruitment strategies for reaching potential eHealth audiences. 相似文献

From the literature three types of predictors for factor scores are available. These are characterized by the constraints: linear, linear conditionally unbiased, and linear correlation preserving. Each of these constraints generates a class of predictors. Best predictors are defined in terms of Lowner's partial matrix order applied to matrices of mean square error of prediction. It is shown that within the first two classes a best predictor exists and that it does not exist in the third. 相似文献

This article introduces a new model for transaction prices in the presence of market microstructure noise in order to study the properties of the price process on two different time scales, namely, transaction time where prices are sampled with every transaction and tick time where prices are sampled with every price change. Both sampling schemes have been used in the literature on realized variance, but a formal investigation into their properties has been lacking. Our empirical and theoretical results indicate that the return dynamics in transaction time are very different from those in tick time and the choice of sampling scheme can therefore have an important impact on the properties of realized variance. For RV we find that tick time sampling is superior to transaction time sampling in terms of mean-squared-error, especially when the level of noise, number of ticks, or the arrival frequency of efficient price moves is low. Importantly, we show that while the microstructure noise may appear close to IID in transaction time, in tick time it is highly dependent. As a result, bias correction procedures that rely on the noise being independent, can fail in tick time and are better implemented in transaction time. 相似文献

AbstractThe twelfth annual MOBIUS Conference was held June 7–9, 2011, at the Holiday Inn Executive Center in Columbia, Missouri. The MOBIUS consortium of Missouri is currently composed of fifty-nine academic libraries, two public libraries, and the Missouri State Library. The conference offered various opportunities, including a keynote address by Meredith Farkas and a networking dessert session on the first night. The second day featured six concurrent sessions, each having six different presentations, along with delicious food, generous door prizes, and the chance to meet with vendors. The third day consisted of four different four-hour post-conference training sessions. Presentations are available for download from the conference Web site.1 相似文献

This article analyzes the available evidence to address airborne, aerosol transmission of the SARS-CoV-2. We review and present three lines of evidence: case reports of transmission for asymptomatic individuals in association with studies that show that normal breathing and talking produce predominantly small droplets of the size that are subject to aerosol transport; limited empirical data that have recorded aerosolized SARS-CoV-2 particles that remain suspended in the air for hours and are subject to transport over distances including outside of rooms and intrabuilding, and the broader literature that further supports the importance of aerosol transmission of infectious diseases. The weight of the available evidence warrants immediate attention to address the significance of aerosols and implications for public health protection. 相似文献
