Nigeria is one of few countries that reports having translated national policies on school-based comprehensive sexuality education (CSE) into near-nationwide implementation. We analysed data using the World Health Organization-ExpandNet framework, which provides a systematic structure for planning and managing the scaling up of health innovations. We examined how Nigeria's nationwide programme was designed and executed. Since 2002, Nigeria has developed a well thought through strategy to scale up CSE. Crucial attributes that facilitated the scaling up included technical consensus about the innovation and clarity about its components, dissection of a complex intervention into manageable components for implementation by organisations with complementary expertise, strong political leadership and championship in concert with advocacy and technical support from non-governmental organisations, proactive and energetic involvement of community stakeholders, effective programme management, and improvements to the information management system to ensure on-track implementation and mid-course corrections to keep stakeholders, including funders, informed and engaged. Challenges included programmatic values, competing priorities for available human resources and a lack of predictable funding for sustaining a rapid scale-up effort. Despite some weaknesses, implementation has largely proceeded according to plan. The lessons learned from Nigeria's experience can and should be used in other settings to achieve wide-scale coverage.  相似文献   

String tension effects on tennis ball rebound speed and accuracy during playing conditions     

Bower R  Cross R 《Journal of sports sciences》2005,23(7):765-771

The primary aim of this study was to determine whether variations in rebound speed and accuracy of a tennis ball could be detected during game-simulated conditions when using three rackets strung with three string tensions. Tennis balls were projected from a ball machine towards participants who attempted to stroke the ball cross-court into the opposing singles court. The rebound speed of each impact was measured using a radar gun located behind the baseline of the court. An observer also recorded the number of balls landing in, long, wide and in the net. It was found that rebound speeds for males (110.1+/-10.2 km.h-1; mean+/-s) were slightly higher than those of females (103.6+/-8.6 km.h-1; P<0.05) and that low string tensions (180 N) produced greater rebound speeds (108.1+/-9.9 km.h-1) than high string tensions (280 N, 105.3+/-9.6 km.h-1; P<0.05). This finding is in line with laboratory results and theoretical predictions of other researchers. With respect to accuracy, the type of error made was significantly influenced by the string tension (P<0.05). This was particularly evident when considering whether the ball travelled long or landed in the net. High string tension was more likely to result in a net error, whereas low string tension was more likely to result in the ball travelling long. It was concluded that both gender and the string tension influence the speed and accuracy of the tennis ball.  相似文献   

Response to intervention as a vehicle for distinguishing between children with and without reading disabilities: Evidence for the role of kindergarten and first-grade interventions     

Vellutino FR  Scanlon DM  Small S  Fanuele DP 《Journal of learning disabilities》2006,39(2):157-169

Children at risk for early reading difficulties were identified on entry into kindergarten, and half of these children received small-group intervention two to three times a week during their kindergarten year. The other half received whatever remedial assistance was offered by their home schools. These children were again assessed at the beginning of first grade, and those who continued to have difficulties in reading received either one-to-one daily tutoring offered by project teachers from the beginning to the end of first grade or whatever remedial assistance was offered by their home schools over the same time period. All target children were periodically assessed through the end of third grade. Results suggest that either kindergarten intervention alone or kindergarten intervention combined with first-grade intervention are both useful vehicles for preventing early and long-term reading difficulties in most at-risk children.  相似文献

Cancer is a genetic disorder.Although heredi-tary cancers account for only a small fraction of all tumors,most cancers are caused by a variable mix of heredity and environment that leads to accumulations of genetic alterations and then uncontrolled cell pro-liferations(Kops et al.,2005).In addition,genetic alteration is one of the a few most important bio-logical factors that determine the diagnosis and prognosis of different cancers and dictate the treat-ment strategies for cancer patients.Fu…  相似文献   

Age-related incidence curve of hospitalized Shaken Baby Syndrome cases: convergent evidence for crying as a trigger to shaking     

Barr RG  Trent RB  Cross J 《Child abuse & neglect》2006,30(1):7-16

OBJECTIVE: To determine whether there is an age-specific incidence of hospitalized cases of Shaken Baby Syndrome (SBS) that has similar properties to the previously reported "normal crying curve," as a form of indirect evidence that crying is an important stimulus for SBS. DESIGN AND SETTING: The study analyzed cases of Shaken Baby Syndrome by age at hospitalization from hospital discharge data for California hospitals from October 1996 through December 2000. PATIENTS: All cases of children less than 18 months (78 weeks) of age for whom the diagnostic code for Shaken Baby Syndrome (995.55) in the International Classification of Disease, Ninth Edition, Clinical Modification was assigned. RESULTS: There were 273 hospitalizations for SBS. Like the "normal crying curve," the curve of age-specific incidence starts at 2-3 weeks, has a clear peak, and declines to baseline by about 36 weeks of age. In contrast to the normal crying curve that peaks at 5-6 weeks, the peak of SBS hospitalizations occurs at 10-13 weeks. CONCLUSIONS: The age-specific incidence curve of hospitalized SBS cases has a similar starting point and shape to the previously reported normal crying curve but the peak occurs about 4-6 weeks later. Of the likely predisposing causes, this pattern is only consistent with the properties of early crying. There are numerous explanations for the lag in the peaks between crying and SBS hospitalizations, including the possibility of repeat shakings prior to hospitalization. The importance of crying as a stimulus to SBS may provide an opportunity for preventive intervention.  相似文献   

Thinking through practice: exploring ways of knowing,understanding and representing the complexity of teaching     

Donna Mathewson Mitchell 《Asia-Pacific Journal of Teacher Education》2013,41(4):414-425

In recent times there has been a cross-disciplinary amplification of interest in the concept of practice. In this context, there is a growing body of research considering how teaching and teacher education might be viewed using the conceptual lens of practice. In this article, I explore practice theories to identify common themes and principles that constitute a conceptual framework for the investigation of the lived experience of teaching. From this foundation, a methodological framework based on collaborative inquiry and postmodern emergence is derived. Examples are offered of the way the conceptual framework and methodological approach have been activated through the first stage of a research programme that collaboratively engages the dual voices of academic researcher and classroom practitioners as co-researchers. Analysis of qualitative data reveals the potential and limitations of this practice-based foundation as a way to know, understand and represent the complexity of teaching. In conclusion, the article develops a number of propositions as the basis for further research.  相似文献

Novice nurses encounter numerous factors that impact on their learning in the complex healthcare workplace. Registered nurses often work one‐on‐one with novices as preceptors to facilitate the development of novices’ clinical skills and socialisation into the profession. This paper explores the concept of preceptorship from novice nurses’ and preceptors’ perspective, drawing upon data from a project between a large healthcare organisation and a university in Melbourne, Australia. The study, framed in ethnomethodology, included fieldwork observation, interviews and student surveys; this paper focuses on data collected over a series of individual interviews with nursing students (n = 28) and preceptors (n = 25). Thematic analysis yielded six key themes: workplace socialisation, empathy, individuality, willingness to engage, changing support and a realisation [by novices about the preceptor role]. Findings highlight the complexity of workplace learning that is influenced by the idiosyncrasies of the individuals involved and the social milieu in which the learning takes place.  相似文献   

Do emotional and behavioural difficulties in primary school predict adolescent victimisation trajectories?     

Leanne Lester  Donna Cross 《Emotional and Behavioural Difficulties》2013,18(4):356-370

Chronic victimisation in adolescence is a traumatic experience with potential negative long-term health consequences. Given that victimisation has been shown to increase over the transition from primary to secondary school, longitudinal data from 1810 students transitioning from primary to secondary school were used to identify victimisation trajectory groups; classified as low-increasing, low-stable, medium-stable and not-bullied. Males with emotional and behavioural difficulties (both internalising and externalising behaviours) and females with externalising behaviours were more likely to be in the increasing and stable victimised groups than the not-bullied group. The results of this study suggest whole-school bullying intervention programmes need to occur before students reach secondary school, and that transition programmes need to emphasise and support social interaction between peers to reduce victimisation and the harms caused by long-term exposure to bullying.  相似文献

Making Ends Meet: Bringing Bilingual Education and Mainstream Students Together in Preservice Teacher Education     

Carol Evans  Elizabeth Arnot-Hopffer  Donna Jurich 《Equity & Excellence in Education》2013,46(1):75-88

In some institutions offering certification for bilingual education and ESL teachers, the corresponding mainstream programs do little to ready their students to work effectively with language minority children. Yet today's mainstream classrooms are linguistically and culturally diverse, and all teachers must appreciate the role of language and culture in teaching and learning. This study describes one effort to consciously combine preservice bilingual and mainstream education teachers in a bilingual education methods cohort. Students reported promising gains in cross-cultural understanding and in cross-program appreciation. Some losses took place as well, however, and further innovation and research are needed in order to ensure that such efforts to combine programs strengthen, but not weaken, each program.  相似文献
