This article reviews our experience, as well as the medical literature, regarding the treatment of failure to thrive (FTT) on an outpatient basis. Nonorganic FTT can be accidental, neglectful, or deliberate. Accidental FTT occurs with errors in formula preparation, diet selection, or feeding technique. These errors can usually be corrected by education and demonstration. Deliberate underfeeding is rare, and these children usually require placement in foster care. Neglectful FTT usually occurs because the mother is overwhelmed or psychologically disturbed. Children with neglectful FTT do not automatically require hospitalization. If the degree of FTT is mild to moderate, the mother-child interaction is positive, the mother is not severely disturbed, and the baby has no inflicted injuries or deprivational behavior, the baby can be safely and more economically managed as an outpatient. Management includes new feeding instructions, a stimulation program, social work intervention, home visits by a public health nurse, and weekly weight checks. Most infants respond to this one-month therapeutic trial with an appropriate weight gain. Even after normal weight is attained, many of these families require long-term follow-up to help them deal with multiple psychosocial issues.  相似文献

This paper discusses a model-based approach to validate software requirements in agile development processes by simulation and in particular automated testing. The use of models as central development artifact needs to be added to the portfolio of software engineering techniques, to further increase efficiency and flexibility of the development beginning already early in the requirements definition phase. Testing requirements are some of the most important techniques to give feedback and to increase the quality of the result. Therefore testing of artifacts should be introduced as early as possible, even in the requirements definition phase.  相似文献

If personal computers (PCs) are used to facilitate learning, then a home computer might be considered a potential input in an educational production function. Using data on British youths from the British Household Panel Survey between 1991 and 2001, this paper explores the link between ownership of a home computer at ages 15 and 17 and subsequent educational attainment in the principal British school examinations taken at ages 16 (GCSEs) and 18 (A-levels). The data show a significant positive association between PC ownership and the number of GCSEs obtained and with the probability of passing five or more GCSEs. These results survive a set of robustness tests, including using other household durables and “future” PC ownership as proxies for household wealth and other unobservable household level effects. Home computer ownership is also associated with a significant increase in the probability of passing at least one A-level and with an increase in the probability of successfully completing three or more A-levels, conditional on having passed at least one A-level.  相似文献

As data collection costs fall and vast quantities of data are collected, data analysis time can become a bottleneck. For massively parallel analyses, cloud computing offers the short-term rental of ample processing power. Recent software innovations have reduced the effort needed to take advantage of cloud computing. To demonstrate, we replicate a voxel-wise examination of the genetic contributions to cortical development by age using evidence from 1748 MRI scans. Specifically, we employ off-the-shelf Kubernetes software that permits us to re-run our analyses using almost the same computer code as was published in the original article. Large, well funded institutions may continue to maintain their own computing clusters. However, the modest cost of renting and ease of utilizing cloud computing services makes unprecedented compute power available to all researchers, whether or not affiliated with a research institution. We expect this to spur innovation in the sophisticated modeling of large datasets.  相似文献

Indicators and instruments for determining and measuring school quality within inspection systems are usually based on frameworks for inspection. These frameworks rely heavily upon school and teacher effectiveness research. Thus, a central assumption is that the effectiveness and improvement-oriented school conditions, as measured within an inspection, are related to student achievement. It is unclear if this assumption really holds true, as empirical evidence is still lacking. This study uses data from a random sampling of schools (n = 37) and teachers (n = 1663) and the achievement data from students (n = 23,943) to validate the interpretations and uses of school inspection results regarding the factor school leadership. The study follows Kane’s argument-based approach for validation. Results reveal that principals of schools with recurrent high student achievement very often demonstrate instructional leadership. It is evident that these principals are also leading in a fundamentally different way from principals in schools with lower achievement in that they lead with the specific school context in mind. The study demonstrates that it is possible to make inferences from scores provided by school inspections and to generalize from them. However, this generalizability does not extend to making extrapolations or decisions based on these scores. The analyses make it clear that providing feedback solely on the strengths and weakness of a school is insufficient when it comes to stimulating school improvement through inspection.  相似文献
