The etiology, pathogenesis, and clinical treatment of stenoses of the isthmus aortae are outlined. Following this, the particular case of a 41-year-old patient with typical stenosis of the isthmus of the aorta is reported. The course of disease required the need for a surgical operation, which had not initially been taken into consideration, to be reexamined. The patient, after performance on him of vascular restoration, is now on a part-time job. Using age as the sole circumstance indicating the inadvisability of performing a surgical operation in the case of stenosis of the isthmus aortae cannot any longer be considered justifiable.  相似文献

Studies have shown that the multiple-stimulus without replacement (MSWO) preference assessment is an effective assessment format for identifying preferred items. However, it is possible that factors other than reinforcer quality might influence selections by some individuals when the MSWO array consists of edible items. The validity of the MSWO results was evaluated by comparing items identified as most and least preferred by the MSWO assessment in a concurrent-schedule (CS) format. Varying edible items were used in each study. The MSWO format accurately identified the higher quality edible item for most participants across studies (76%); however, the MSWO format did not predict the highest quality edible item in the CS assessment for 20% to 30% of participants in each study.  相似文献

Researchers have used multicomponent behavioral skills training packages including written and verbal instructions, modeling, rehearsal, and feedback when teaching caregivers to implement pediatric feeding treatment protocols (e.g., Anderson & McMillan, 2001; Seiverling et al., 2012). Some investigators have shown that fewer behavioral skills training components may be necessary for effective training (e.g., Mueller et al., 2003; Pangborn et al., 2013). We examined the use of in-vivo feedback following written instructions to train caregivers to implement pediatric feeding treatment protocols using a multiple baseline design across 3 caregiver dyads. Correct implementation of the feeding treatment procedures was low during baseline (written instructions only), increased with only the addition of in-vivo feedback, and remained high during follow-up sessions for all caregivers. Results are discussed in terms of clinical implications and caregiver satisfaction.  相似文献

In the present study, we examined the impact of the interaction of environmental and task-induced attentional focus on time perception, specifically awareness of the time flow. We tested 48 participants in either a natural or urban setting over three 25- to 35-min sessions. We manipulated the within-subjects factor task by means of two tasks—one requiring directed attention on the task itself, the other undirected attention on the environment—alongside a control condition with no specific task. We measured time awareness, passage of time judgments, felt time judgments, and estimated time as dependent variables. For time awareness, we found an interaction between environment and task: in the natural environment, only a task requiring directed attention reduced time awareness; whereas, in the urban environment, both tasks reduced time awareness compared to the control condition. The results suggest that natural environments increase time awareness unless we focus our attention on a task.  相似文献

This study evaluated the effectiveness of using a university‐based pyramidal approach (i.e., train the trainer) to teach four pre‐service teachers to train another person. These pre‐service teachers were taught to use behavioral skills training (BST) techniques to train other professionals to use an evidence‐based practice. Transfer to a generalization trainee was probed and three participants maintenance of BST fidelity was probed one year later, after the participants had begun teaching. Results indicate that the participants quickly acquired and maintained a high degree of fidelity with BST. Implications for research and practice are discussed.  相似文献
