Louisa R. Peralta  Donna O’Connor  Wayne G. Cotton  Andrew Bennie 《Teaching Education》2016,27(3):248-266

In this paper, we investigate the effects of a community- and school-based service learning experience (SLE) on pre-service physical education teachers’ Indigenous knowledge, cultural competency and pedagogy. Informed by the theoretical tenets of Indigenous research methodologies, experiential learning and critical reflection, we examine 55 final-year pre-service physical education teachers’ (age: 21.9 [8.3]; 10.7% low SES; 68% females) cultural learning and competency in a core unit of study with a six-week SLE. Measures of their experiences included reflective journals, multicultural teaching competency scales and focus group interviews. Findings support the design of the SLE, with statistically significant changes in pre-service teachers’ perceptions of their cultural competency (p < 0.001). Pre-service teachers were able to challenge their assumptions about Indigenous students, plan and implement student-centred and culturally relevant pedagogies. Attention is drawn to the design of this SLE and demonstrates the importance of using Indigenous community members and teachers as mentors, which has not been explored in previous SLE studies.  相似文献   

Improving the learning of Boolean queries by means of a multiobjective IQBE evolutionary algorithm     

O. Cordón  E. Herrera-Viedma  M. Luque 《Information processing & management》2006

The Inductive Query By Example (IQBE) paradigm allows a system to automatically derive queries for a specific Information Retrieval System (IRS). Classic IRSs based on this paradigm [Smith, M., & Smith, M. (1997). The use of genetic programming to build Boolean queries for text retrieval through relevance feedback. Journal of Information Science, 23(6), 423–431] generate a single solution (Boolean query) in each run, that with the best fitness value, which is usually based on a weighted combination of the basic performance criteria, precision and recall.  相似文献   

Acrosin activity in spermatozoa of infertile Nigerian males     

M. A. Emokpae  P. O. Uadia 《Indian journal of clinical biochemistry : IJCB》2006,21(1):199-201

The objective of this study was to evaluate acrosin activity in spermatozoa of infertile Nigerian men and to compare with those of the fertile men. The acrosin activity was evaluated using the Acroscreen reagent kit. The acrosin activity of the fertile men was 40.7±5.2 mIU/10⁶ sperm (range 30.1–51.3) and those of the infertile men was 22.4±8.33 mIU/10⁶ sperm (range 5.7–39.1). The difference in the mean was statistically significant (P<0.001). There was a subpopulation of the infertile men who had their acrosin activity within normal range of the fertile men, 32.9±1.57 mIU/10⁶ sperm. But the difference in the mean was statistically significant (P<0.001). Acrosin activity decreased with increased morphological changes in the spermatozoa. It is concluded that acrosin activity in the infertile Nigerian men is significantly lower than that in the fertile men. Acrosin activity may also be affected by morphological changes in the spermatozoa.  相似文献   

pre-operative serum potassium levels and peri-operative outcomes in patients undergoing cardiac surgery     

O. P. Sanjay 《Indian journal of clinical biochemistry : IJCB》2004,19(1):40-44

Although potassium is critical for normal electro physiology, the associations between pre-operative serum potassium level and peri-operative adverse events such as arrhythmias in cardiac surgery have not been examined in detail. The objective of this study was to determine the prevalence of abnormal pre-operative serum potassium levels and whether such levels were associated with adverse peri-operative events in 50 patients undergoing coronary artery bypass grafting. Intra-operative and post-operative arrhythmias, the need for cardio-pulmonary resuscitation, cardiac death and death due to any cause prior to discharge from the post-operative intensive care unit were studied. The incidence for adverse outcome was 0.5% for death, 0.5% for cardiac death and 2% for cardio pulmonary resuscitation in patients with hypokalemia (serum potassium level <3.5 meq. L⁻¹). Hypokalemia was found to be a predictor of serious peri-operative (OR:2.2; 95% Cl: 1.2–4.1) and post-operative arrhythmias (OR: 1.7;95%Cl: 1.0–2.7). Pre-operative potassium repletion is low cost and low risk treatment measure and the data from this study suggests that screening and repletion be considered in patients scheduled for cardiac surgery.  相似文献   

Planning for a pandemic influenza outbreak: roles for librarian liaisons in emergency delivery of educational programs   总被引：1，自引：0，他引：1  

McGuire L 《Medical reference services quarterly》2007,26(4):1-13

In February 2006, two librarians at the University of Minnesota's Bio-Medical Library were asked to participate in a task force at the University of Minnesota's School of Public Health (SPH). The charge from the dean of SPH was to determine how the school could continue to deliver its educational programs in the event of a pandemic influenza outbreak. This paper will outline the work of the task force, discuss its recommendations, and offer ideas on how other librarians can work with their liaison areas to plan for a similar project.  相似文献   

The role of gender constancy in early gender development     

Ruble DN  Taylor LJ  Cyphers L  Greulich FK  Lurye LE  Shrout PE 《Child development》2007,78(4):1121-1136

Kohlberg's (1966) hypothesis that the attainment of gender constancy motivates children to attend to gender norms was reevaluated by examining these links in relation to age. Ninety-four 3- to 7-year-old children were interviewed to assess whether and how constancy mediates age-related changes in gender-related beliefs. As expected, results indicated a general pattern of an increase in stereotype knowledge, the importance and positive evaluation of one's own gender category, and rigidity of beliefs between the ages of 3 and 5. Moreover, the stability phase, rather than full constancy, mediated some of these relations. After age 5, rigidity generally decreased with age, with relations primarily mediated by consistency.  相似文献   

Do Children's Advocacy Centers improve families' experiences of child sexual abuse investigations?     

Jones LM  Cross TP  Walsh WA  Simone M 《Child abuse & neglect》2007,31(10):1069-1085

OBJECTIVE: The Children's Advocacy Center (CAC) model of child abuse investigation is designed to be more child and family-friendly than traditional methods, but there have been no rigorous studies of their effect on children's and caregivers' experience. Data collected as part of the Multi-Site Evaluation of Children's Advocacy Centers were used to examine whether CACs improve caregivers' and children's satisfaction with investigations. METHODS: Nonoffending caregiver and child satisfaction were assessed during research interviews, including the administration of a 14-item Investigation Satisfaction Scale (ISS) for caregivers. Two hundred and twenty-nine sexual abuse cases investigated through a CAC were compared to 55 cases investigated in communities with no CAC. RESULTS: Hierarchical linear regression results indicated that caregivers in CAC cases were more satisfied with the investigation than those from comparison sites, even after controlling for a number of relevant variables. There were few differences between CAC and comparison samples on children's satisfaction. Children described moderate to high satisfaction with the investigation, while a minority expressed concerns about their experience. CONCLUSIONS: The CAC model shows promise for improving families' experiences, but to build upon this promise, agencies will need to systematize procedures for refining and adapting the model as new research becomes available.  相似文献   

Child forensic interviewing in Children's Advocacy Centers: empirical data on a practice model     

Cross TP  Jones LM  Walsh WA  Simone M  Kolko D 《Child abuse & neglect》2007,31(10):1031-1052

OBJECTIVE: Children's Advocacy Centers (CACs) aim to improve child forensic interviewing following allegations of child abuse by coordinating multiple investigations, providing child-friendly interviewing locations, and limiting redundant interviewing. This analysis presents one of the first rigorous evaluations of CACs' implementation of these methods. METHODS: This analysis is part of a quasi-experimental study, the Multi-Site Evaluation of Children's Advocacy Centers, which evaluated four CACs relative to within-state non-CAC comparison communities. Case abstractors collected data on investigation methods in 1,069 child sexual abuse cases with forensic interviews by reviewing case records from multiple agencies. RESULTS: CAC cases were more likely than comparison cases to feature police involvement in CPS cases (41% vs. 15%), multidisciplinary team (MDT) interviews (28% vs. 6%), case reviews (56% vs. 7%), joint police/child protective services (CPS) investigations (81% vs. 52%) and video/audiotaping of interviews (52% vs. 17%, all these comparisons p<.001). CACs varied in which coordination methods they used, and some comparison communities also used certain coordination methods more than the CAC with which they were paired. Eighty-five percent of CAC interviews took place in child-friendly CAC facilities, while notable proportions of comparison interviews took place at CPS offices (22%), police facilities (18%), home (16%), or school (19%). Ninety-five percent of children had no more than two forensic interviews, and CAC and comparison differences on number of interviews were mostly non-significant. CONCLUSIONS: Relative to the comparison communities, these CACs appear to have increased coordination on investigations and child forensic interviewing. The CAC setting was the location for the vast majority of CAC child interviews, while comparison communities often used settings that many consider undesirable. CACs showed no advantage on reducing the number of forensic interviews, which was consistently small across the sample.  相似文献   

Together I Can! Joint Attention Boosts 3- to 4-Year-Olds’ Performance in a Verbal False-Belief Test     

Elia Psouni  Andreas Falck  Leni Boström  Martin Persson  Lisa Sidén  Maria Wallin 《Child development》2019,90(1):35-50

Effects of joint attention were addressed on 3- to 4-year-olds’ performance in a verbal false-Belief Test (FBT), featuring the experimenter as co-watcher rather than narrator. In two experiments, children (N = 183) watched a filmed-FBT jointly with a test leader, disjointed from a test leader, or alone. Children attending jointly with a test leader were more likely to pass the FBT compared with normative data and to spontaneously recall information indicating false-belief understanding, suggesting that joint attention strengthens the plausibility of the FBT and renders plot-critical information more salient. In a third experiment (N = 59), results were replicated using a typical, image-based FBT. Overall findings highlight the profound impact of experimenter as social context in verbal FBTs, and link recall of specific story features to false-belief understanding.  相似文献   

Getting a Read on Ready To Learn Media: A Meta-analytic Review of Effects on Literacy     

Lisa B. Hurwitz 《Child development》2019,90(5):1754-1771

Most U.S. preschoolers have consumed media created with funding from the U.S. Department of Education's Ready To Learn (RTL) initiative, which was established to promote school readiness among children ages 2–8. Synthesizing data from 45 evaluations (N = 24,624 unique child participants), this meta-analysis examined the effects of RTL media exposure on young children's literacy skills. Results indicate positive effects of RTL media exposure on children's literacy outcomes, especially vocabulary and phonological concepts. These effects are equivalent to about one-and-a-half months of literacy learning above and beyond typical growth. Findings are robust across a variety of research designs and for exposure to both television and new media. These results are discussed in terms of accountability evidence for RTL and larger debates in scholarly understanding of educational media effects.  相似文献
