Development of the student placement evaluation form: A tool for assessing student fieldwork performance

Evaluation of students undertaking fieldwork education placements is a critical process in the health professions. As training programs and practice evolve, systems for assessing students need to be reviewed and updated constantly. In 1995, staff of the occupational therapy training program at the University of Queensland, Australia decided to develop a new tool for assessing student fieldwork performance. Using an action research methodology, a team developed the Student Placement Evaluation Form, a flexible and comprehensive criterion-referenced evaluation tool. The present paper examines action research as an appropriate methodology for considering real-life organisational problems in a systematic and participatory manner. The action research cycles undertaken, including preliminary information gathering, tool development, trial stages and current use of the tool, are detailed in the report. Current and future development of the tool is also described.     

无名异冲剂促进去卵巢大鼠骨质疏松性骨折愈合的机制研究

为探讨无名异冲剂促进去卵巢 SD大鼠骨质疏松性骨折愈合的机制 ,用 48只 6月龄雄性 SD大鼠建立骨质疏松性骨折模型 ,随机分为模型组、跳骨片组、仙灵骨葆组、无名异冲剂组 ,于灌胃后 2周、4周取材 ,观察 X线片、骨密度、光镜 ,骨痂钙、磷、胶原含量 ,结果显示灌胃第 2周时 ,各组动物各项指标均无显著性差异 ;第4周时 ,无名异冲剂组的骨密度 ,骨痂钙、磷、胶原含量的检测结果与模型组有显著性差异 ( P<0 .0 5 ) ,X线及光镜观察骨痂的生长情况 ,无名异冲剂组也优于模型组 ,说明无名异冲剂能够通过提高骨密度 ,改善骨骼钙、磷、胶原的代谢 ,促进骨折端骨痂的生长 ,达到治疗骨质疏松性骨折的目的。     

提高与保证生物化学教学质量的探讨

随着生物化学和分子生物学的快速发展,生物化学的理论和技术被广泛应用于各种研究领域.因此不断提高教师的业务素质、采用先进的教学手段和教学模式、改革生物化学的实验教学,是提高与保证生物化学教学质量的前提,也是衔接后期研究生教学的重要环节.     

大学新生心理健康状况的调查研究

目的　了解大学新生的心理健康状况 ,探讨提高其心理健康水平的措施。方法　采用大学生人格问卷(UPI) ,以班级为单位 ,在新生正式上课两周以后进行测试。结果　学生一类筛选率 9.2 4 %。UPI关键题选择中 ,以常常失眠占的比例最高 ,想轻生的比例最低 (P <0 .0 5 )。UPI附加题选择中 ,以自身健康方面有问题及有健康或心理卫生方面想要咨询的问题较多 (P <0 .0 5 )。选择“想轻生”的男生的比例略高于女生 ,选择“常常失眠”的女生的比例却明显高于男生 (P <0 .0 5 ) ;选择“常常失眠”、“对任何事情都不感兴趣”和“感觉自己的过去及家庭不幸”的农村学生的比例都高于城市学生 (P <0 .0 5 )。选择“想轻生”和“对任何事情都不感兴趣”的独生子女的比例明显高于非独生子女 ,而选择“自己的过去和家庭是不行的”和“常常失眠”的非独生子女的比例又明显高于独生子女 (P <0 .0 5 )。结论　单亲家庭学生、残疾学生、家庭经济困难学生、独生子女学生是心理问题高危人群     

Adolescent alcohol initiation: A review of psychosocial risk factors

Longitudinal research studies focused on alcohol use initiation in adolescence were reviewed to determine which variables function as antecedent predictors or risk factors. Only studies that focused on time-1 abstainers were included. Classes of risk factors examined include sociodemographic, family, peer, personality, and behavioral variables. The most consistent antecedent risk factors for starting to drink in adolescence were parental and peer approval and models for drinking and drug use as well as adolescents’ own prior involvement in delinquent behavior. There was little evidence for gender differences in risk factors for alcohol use initiation. Secondary analyses of existing longitudinal data sets are encouraged to examine whether there are ethnic/racial differences in the risk factors for starting to drink and to establish those factors that serve a protective or buffering function, delaying onset of alcohol use in adolescence.     

四种中药对骨愈合过程中相关基因表达的影响

目的:探索中药水蛭、海螵蛸、阿胶、骨碎补在骨折愈合过程中的干预作用,了解它们各自的调节靶点,探索建构其基因组学的途径。方法:通过在大鼠胫骨打孔的方法建立单因素干扰模型,并将300只大鼠随机分为正常组、模型组和给药组(分别用4种中药给药),每组50只,分别在实验的第4、7、14、21、28天不同时间点采用原位杂交方法对各类mRNA的变化进行动态观察,分析骨愈合过程中Ⅰ、Ⅱ、Ⅲ型前胶原mRNA、转化生长因子TGF-β1mRNA、骨形态发生蛋白BMP-2mRNA以及血管内皮生长因子VEGF-mRNA的表达情况。结果:不同中药对不同基因的作用不同,作用的时间点不同,作用强度也存在差异。其中海螵蛸在骨折早期对Ⅰ、Ⅲ型前胶原mRNA、VEGF-mRNA、BMP-2mRNA的表达升高,后期Ⅱ、Ⅲ型前胶原mRNA表达水平下降,VEGF-mRNA、TGF-β1mRNA表达量维持于较高水平;骨碎补组较模型组在BMP-2mRNA、TGF-β1mRNA、Ⅰ型前胶原mRNA的表达上差异有显著性统计意义;阿胶对骨愈合早、中期Ⅰ、Ⅱ、Ⅲ型前胶原mRNA和TGF-β1mRNA的表达与模型组比较差异存在显著性统计意义;水蛭对VEGF-mRNA的表达具有一定的促进作用。结论:海螵蛸、水蛭对血管形成有促进作用,阿胶、骨碎补和海螵蛸对骨折软骨形成早期具有促进骨诱导的作用,并对成骨细胞的增殖及合成活性有较大影响。     

个体成长模型在纵向研究中的应用--以大学新生交往主动性为例

An exploration of gifted programs

This article presents findings on an exploration of gifted programs in the state of Missouri. Over 60 percent of the state supported public school gifted programs participated in the study. The study concludes that the guidelines for gifted education in Missouri create extreme variability in the standards of the programs. Strong national policy for gifted education is needed to insure gifted children are properly served and protected by law.     

Case Study of Institution-Building by Nurse Bertha Wright and Colleagues

Purpose: To illuminate the history of nurses' participation in institution-building in the early 1900s, using the Baby Hospital in Oakland, California (now called Children's Hospital Oakland) as a case.
Design: Historical research using a framework of women's history theory focused on the women who founded Oakland's Baby Hospital, 1910–1930.
Method: Data collection included studying original sources, archival material, and interviews. Data evaluation included external criticism for authenticity and genuineness, and internal criticism for accuracy and bias.
Findings: In 1912, nurse Bertha Wright and social worker Mabel Weed, with a circle of community women, including Jessica Peixotto and Jean Howard McDuffie, established the Baby Hospital. Their activism included home visits, education, research, publications, political lobbying, and state policy and program development. At the center of this activity, was the lifelong commitment of Wright and Weed, who created new definitions of family. With social changes in the late 1920s, the male Board of Directors seized control of the hospital, and relegated women to auxiliary roles.
Conclusions: Health and social issues of the United States at the turn of the century are still problematic as a new century approaches and pertain to maternal-child health, foster care, and immigration. Feminists, including nurses, have played a central role in creating solutions. Knowledge of some of their incredible effort has been lost, particularly nursing's history in the western United States.
