Fatal and nonfatal injuries due to suicidal behavior among younger adolescents are of growing concern for many communities. We examined the incidence and patterns of these injuries among persons aged 10-14 years using three databases, two national and a third from Oregon. Suffocation and firearm gunshot were the leading external causes of suicide; poisoning and cutting/piercing were the leading causes of nonfatal self-harm injuries. The most common psychosocial factors associated with those treated in emergency departments for self-harm injuries were psychological conditions; drug/alcohol involvement; and adverse circumstances, including family discord, school problems, and physical/sexual abuse. Analysis of population-based data from these databases are part of the public health approach and can help direct much needed research and prevention efforts that address self-harming behavior in these younger adolescents.  相似文献

Evaluation is an important management tool used by managers and beneficiaries of development projects. However, until recently, only the managers and external agencies evaluated project benefits, and there was little interaction with the beneficiaries. This approach to evaluation ignores the locally available evaluation capacity that could be harnessed not only for meaningful evaluation, but also for rational decision-making at the project level. This article, using some experience from a Village Hydro Project in Sri Lanka, demonstrates the value and relevance of using local capacity in project evaluations. When local capacity is combined with external formal evaluation exercises, not only does the evaluation become more enlightened and participatory, but more importantly, the beneficiaries become partners in development. The article argues that such local capacity could start as an informal evaluation system that could gradually be transformed into a formal evaluation system.  相似文献

Deficits in identification and discrimination of sounds with short inter-stimulus intervals or short formant transitions in children with specific language impairment (SLI) have been taken to reflect an underlying temporal auditory processing deficit. Using the sustained frequency following response (FFR) and the onset auditory brainstem responses (ABR) we evaluated if children with SLI show abnormalities at the brainstem level consistent with a temporal processing deficit. To this end, the neural encoding of tonal sweeps, as reflected in the FFR, for different rates of frequency change, and the effects of reducing inter-stimulus interval on the ABR components were evaluated in 10 4–11-year-old SLI children and their age-matched controls. Results for the SLI group showed degraded FFR phase-locked neural activity that failed to faithfully track the frequency change presented in the tonal sweeps, particularly at the faster sweep rates. SLI children also showed longer latencies for waves III and V of the ABR and a greater prolongation of wave III at high stimulus rates (>30/sec), suggesting greater susceptibility to neural adaptation. These results taken together appear to suggest a disruption in the temporal pattern of phase-locked neural activity necessary to encode rapid frequency change and an increased susceptibility to desynchronizing factors related to faster rates of stimulus presentation in children with SLI.  相似文献
