Young children enter kindergarten with varying levels of readiness and abilities to learn. One factor that contributes to lower levels of school readiness is poverty. One timely, cost-effective, and feasible strategy to boost school readiness, regardless of exposure to high-quality preschool is to leverage the summer months prior to kindergarten entry and provide comprehensive, evidence-based programming immediately before the school year begins. The current study implemented a community-based summer programme targeted at improving school readiness for 25 four- and five-year-old children in a low-income community. Across the 9-week study, children participated in two types of early literacy activities and the Incredible Years social/emotional learning curriculum. Results indicate that participants demonstrated significant growth across three early literacy skills and were rated as overall stable regarding their behaviour across the summer. These results are discussed along with implications and future directions in this line of research. 相似文献

目的调查四川省基层医院专科护士使用和考核现状,对其使用和考核体系进行探索。方法于2017年9月7-15日,采用问卷调查法对四川省38所二级及三级乙等医疗单位专科护士的使用和发展现状进行调查。结果共有38所医院参与网络问卷调查,其中34.21%的医院未针对专科护士设置岗位,岗位职责不清晰。有73.68%的专科护士未进行资质再认证,60.53%的专科护士学成后未进行专科资质再考核。结论我国对专科护士能力的评价认证体系尚未形成统一标准,对专科护士的培养条件也未形成统一标准。护士岗位管理中设置专科护士岗位能促进专科护士的职业发展规划,有利于专科护士使用和考核。 相似文献

吉林省经七年来的鼠情监测,基本查清与人们接触密切的鼠类,特别是传播疾病的主要鼠类的分布规律,分析出我省家鼠有两个高峰(6月和10~11月),野鼠也有两个高峰(6月和10月),这与我省流行性出血热两个高峰相吻合,鼠峰在病峰之前。1986年以后,由于我省开展大规模灭家鼠活动,家鼠高峰已不存在规律性。通过几年来的灭鼠活动,使家鼠密度呈下降趋势,城镇褐家鼠和小家鼠构成比发生变化。城镇未爆发家鼠型流行性出血热。鼠情监测为灭鼠防病工作提供了科学依据。 相似文献

BackgroundChildren born of low birth weight (LBW) and/or premature may have developmental delays and difficulties. The vulnerability, without early intervention, would have detrimental lifelong effects.ObjectivesThis study examined 1) the relationship between LBW and prematurity and the occurrence and timing of children's receipt of developmental and special education services; and 2) whether poverty intersects with LBW and prematurity affecting service receipt.MethodsThis population-based study used cross-sectional data from the National Survey of Children's Health which consisted of approximately 52,000 participants aged 1–17 between 2017 and 2018 in the United States. We conducted logistic regression to analyze the predictive relationship of LBW/prematurity and the occurrence of receiving developmental and special education services. We then conducted ordered logistic regression to examine whether LBW and prematurity predicted the timing of receiving developmental and special education services. Further, we conducted moderating analyses to examine whether the predictive relationships above varied with poverty. The analyses listed above were weighted to reflect the population drawn.ResultsChildren born with LBW and prematurity were more likely to receive developmental and special education services and they tended to receive services earlier than those born at normal weight and term. Educational disparities were evident among children in low-income families. Children of LBW in low-income families were less likely to receive earlier services than those in affluent families.ConclusionsThis study indicates developmental and special education needs of children born LBW and/or premature. With restrained assets, low-income families may need more assistance to promote optimal development for their children. 相似文献

BackgroundChildren and youth with intellectual and developmental disabilities (IDD) experience health disparities. What is unknown is if data collected from children and youth with IDD who participate in Special Olympics is representative of children and youth with IDD who do not.ObjectivesAim 1: determine the feasibility of matching a database of registrants from Special Olympics Ontario (SOO), with population-based health services databases in Ontario, Canada housed at ICES. Aim 2: evaluate the differences between the database sources with regards to demographic variables and clinical status.MethodsUsing deterministic and probabilistic matching, registration data from SOO were matched to administrative health databases. Established algorithms were used to determine the prevalence of asthma, diabetes, and mental disorder in addition to demographic variables.ResultsThe matching rate was over 90%; 8404 were attributed to children and youth between the ages of 0–19 years. When comparing SOO participants with IDD to non-SOO participants with IDD, children and youth who participate in SOO were, on average, older with no further differences between groups on clinical or demographic variables. When comparing those previously not identified in the health services databases (from SOO) to those with IDD identified by ICES, the SOO participants appear to use the health system less, possibly indicating a better health status.ConclusionsResearch conducted on child and youth who participate in Special Olympics Ontario can be generalized to the broader population of children and youth with IDD in Canada when adjusted for age; however, care should be taken when comparing levels of overall morbidity. 相似文献
