In summary, the Circle House Residential Treatment Program for abusive families did meet its goals of protection of the child without separation from the family. The program was also effective in making and executing permanent plans for children in a relatively short period of time, but at huge financial cost.Residential care tor abusive families may be feasible if planned for 12–18 families at a time, thus utilizing staff fully. Also, in the Circle House program the single-parent families were clearly able to utilize the program to deal with their child-care techniques. Because the program was primarily geared to improving child-rearing patterns, some fathers in two-parent families, who viewed themselves as only occasional disciplinarians, never really participated in the program. Some were successful in learning new techniques, others were not.Residential care may also be more feasible if utilized as a diagnostic and prognostic facility with enhanced opportunity for long-term relationships to be formed, rather than as a primarily treatment facility, with the expectation of improvement and “cure.” Treatment of abusive families then becomes long-term supportive care no matter how intense the initial intervention. Even with the multitude of services of Circle House at the beginning phase of diagnosis and treatment of a family, this does not reduce or remove the need for ongoing long-term services. The true results of present intervention will be measured in future generations.  相似文献

This study designed and evaluated the efficacy of a manualised programme for children in mainstream school with delays in narrative discourse. Efficacy was evaluated using a Phase 1 non-randomised single-subject across multiple-baselines design. The programme was delivered by a speech pathologist with 11 mainstream children aged 5;0–5;11 years, in small groups, three times a week for 6 weeks. Intervention focused on explicit teaching of narrative macrostructure using icons, graphic organisers and repeated story retellings. Microstructure (morphosyntax and vocabulary) was targeted using implicit language facilitation procedures including modelling, recasting, expansion and vertical structuring. Participation in the programme resulted in significant changes with moderate to large effect sizes for most participants in the number of macrostructure elements, and conjunctions and adverbs. Analysis of pre-post standardised narrative data revealed clinically significant improvements for 9 of the 11 participants. The findings add to the research supporting the effectiveness of small-group oral narrative intervention.  相似文献

Our purpose was to compare the effect of a periodized preparation consisting of power endurance training and high-intensity power training on the contractile properties of the quadriceps muscle and functional performances in well trained male sprinters (n = 7). After 4 weeks of high-intensity power training, 60-m sprint running time improved by an average of 1.83% (SD = 0.96; p < .05). This improvement was inversely related to an increase in maximal voluntary contraction torque (r = -.89, p < .05) and poorly correlated with changes in the contractile kinetics of the quadriceps muscle (r range from .36 to -.46). These findings suggest that sprint performance is poorly predicted by muscle intrinsic properties and that a neural adaptation appears to explain most of the observed functional adaptations.  相似文献

Purpose: Some adults with type 2 diabetes mellitus (T2DM) have comorbidities and mobility impairments that limit their exercise capacity. In consideration of this, we developed and piloted a program called Active Steps for Diabetes for people with T2DM, comorbidities, and mobility impairments. The purpose of this paper was to report outcomes for the pilot program. Methods: Active Steps for Diabetes, an 8-week program, included instruction on diabetes self-care andgroup and home exercise programs. Twenty-two females (62.7 ± 6.1yrs) with T2DM and self-reported mobility impairments completed the program. Six participants used a walking aid. Outcome measures included two risk factors for coronary artery disease [daily physical activity and body mass index (BMI)], cardiovascular fitness (6-minute walk distance), and knowledge of diabetes-specific exercise guidelines. A two-way repeated measures ANOVA was used to compare outcomes before and after the program and between participants who did and did not use a walking aid. Results: Active Steps for Diabetes was effective in increasing daily physical activity in both groups of subjects (walking aid group: 2.6 days/week [95% confidence interval (CI) = 2.1 to 3.3]; no walking aid group: 1.9 days/week [95% CI=1.2 to 2.5]). This was accompanied by increases in 6-minute walk distances (walking aid group: 54.0 m [95% CI = 36.4 to 71.6]; no walking aid group: 62.6 m [95% CI=55.7 to 69.4]). Changes in BMI were not significant (walking aid group: −0.4 [95% CI = −1.2 to 0.4]; no walking aid group: −.24[95% CI = −.91 to .44]). Increases in knowledge of diabetes-specific exercise guidelines were observed in both groups (walking aid group: 18.8% [95% CI = 11.3 to 26.4]; no walking aid group: 19.3% [95% CI = 16.1 to 22.5]). Discussion:: Physical inactivity and low cardiovascular fitness are predictors of CAD morbidity and mortality in adults with T2DM. This pilot program suggests that a model for diabetes education, incorporating exercise programs developed by a physical therapist, may increase physical activity, improve endurance, and thereby potentially reduce CAD risk in people with T2DM and mobility impairments from comorbidities.Key Words: type 2 diabetes, physical activity  相似文献

A historical and theoretical analysis of the copyright environment demonstrates that both the economic rights associated with copyright and the moral rights often associated with copyright perform social functions. The latter have not been as universally embraced or adopted as the former. The lack of enthusiasm for moral rights is argued to be because the social utility of this aspect of the copyright regime has gone largely unrecognized. In fact, moral rights ensure that the information needs of the public are being met because they enhance the ability to assess the authority and reliability of information. While historically this has not been as important as enhancing the supply of information, a function performed by the economic rights of copyright, in the context of the new information environment, the role played by moral rights is becoming increasingly important. Our thesis also defines the appropriate scope of moral rights protection in copyright.  相似文献

This is part of a new series in this regular feature regarding trends in the provision of information by health science libraries. By sharing expertise and drawing together relevant trends the series intends to serve as a road map for both health science librarians and health informatics professionals. This article shows how a medical and biomedical research library changed practices, and reassessed user needs for the COVID‐19 emergency. Discusses changes to online education (and collaborative working) to provide user‐friendly services, researcher support tailored to need and re‐visioning library space. J.M.  相似文献
