Many children with severe developmental disabilities emit idiosyncratic gestures that may function as verbal operants (Sigafoos et al., 2000). This study examined the effectiveness of a functional analysis methodology to identify the variables responsible for gestures emitted by 2 young children with severe developmental disabilities. Potential verbal operants for each participant were functionally analyzed using a multi-element design. Results indicate that gestures were maintained by access to tangible items or the delivery of information about novel stimuli. This study extends the use of functional analysis to identify conditions under which children with developmental disabilities emit gestural verbal behavior. 相似文献

Developing a sense of purpose is both salient and desirable for adolescents, and purpose in people's lives and careers is associated with both general and work-related well-being. However, little is known about whether purpose can be encouraged through school-based interventions. This article reports the results of a quasi-experimental pilot study and follow-up focus group that evaluated Make Your Work Matter, a three-module, school-based intervention designed to help adolescent youth explore, discover, and enact a sense of purpose in their early career development. Participants were eighth-grade students. Compared to the control group, the intervention group reported increases in several outcomes related to purpose-centered career development, such as a clearer sense of career direction; a greater understanding of their interests, strengths, and weaknesses; and a greater sense of preparedness for the future. However, no significant differences were found on items directly related to purpose, calling, and prosocial attitudes. These results inform the ongoing development of Make Your Work Matter and other school-based career interventions and pave the way for larger-scale trials of such purpose-promoting intervention strategies. 相似文献

The benefits of understanding and pursuing one's purposes in life are well documented. However, few studies have addressed potential interventions for enhancing purpose. This article presents the results of an empirical investigation testing whether reflecting on and discussing one's core values, life goals, and purposes in life has benefits for later purpose, as well as later life satisfaction. The study involved a pretest/posttest experimental design with 102 college students, with posttest measures administered nine months later. Results showed that those who engaged in the guided discussion of their values, life goals, and purpose (compared to those who did not) benefited in terms of their goal directedness and life satisfaction and that the benefits for life satisfaction were partially attributable to changes in goal directedness. The article concludes by highlighting implications for practitioners of all kinds, including parents, with recommendations for implementing the purpose discussion in a variety of youth settings. 相似文献

The Swiss legal system places strong emphasis on risk assessment and treatment of potentially violent offenders. Especially after the 2001 Zug massacre, there is close cooperation between the judicial and mental health systems to prevent violence through early detection and intervention. A case study of a risk management program for a dangerous seventeen-year-old delinquent youth illustrates this approach. 相似文献

Regulations on the availability of alcohol have been used to moderate alcohol problems in communities throughout the world for thousands of years. In the latter half of the 20th century, quantitative studies of the effects of these regulations on drinking and related problems began in earnest as public health practitioners began to recognize the full extent of the harmful consequences related to drinking. This article briefly outlines the history of this work over four areas, focusing on the minimum legal drinking age, the privatization of alcohol control systems, outlet densities, and hours and days of sale. Some historical background is provided to emphasize the theoretical and empirical roots of this work and to highlight the substantial progress that has been made in each area. In general, this assessment suggests that higher minimum legal drinking ages, greater monopoly controls over alcohol sales, lower outlet numbers and reduced outlet densities, and limited hours and days of sale can effectively reduce alcohol sales, use, and problems. There are, however, substantial gaps in the research literature and a near absence of the quantitative theoretical work needed to direct alcohol-control efforts. Local community responses to alcohol policies are complex and heterogeneous, sometimes reinforcing and sometimes mitigating the effects of availability regulations. Quantitative models of policy effects are essential to accelerate progress toward the formulation and testing of optimal control strategies for the reduction of alcohol problems. 相似文献

The agency has received significant local and national attention for the success of its targeted program model and continuum of care services. The history of Larkin Street Youth Services provides an example of the important role of internal operations in an agency's ability to re-invent itself and respond to a larger community need. 相似文献

BANANAS emerged as a grassroots effort initiated by a group of female volunteers who sought to build a network of women with children who needed childcare.

Beginning as a collective, BANANAS has grown into a multifaceted service delivery and advocacy nonprofit operating with an annual budget of $12 million. This history of the agency reflects the development of a unique community-based effort, its challenges and rewards, and the multiple successes that this pioneering nonprofit has experienced. 相似文献
