Sport-based mentoring programs have been used across many contexts to engage young people in education. In this research, we explored the influence that an Aboriginal controlled organisation’s youth mentoring program has on three remote Aboriginal communities in Northern Territory, Australia. We used a composite set of culturally sensitive methods by including artefacts from the community members and mentees, informal interviews with community, and semi-structured conversations with mentors and schoolteachers. The findings demonstrate the positive feelings, many benefits, and relationships that had been established between mentors and mentees, the organisation and community over time. However, participants also suggested that it would be beneficial to engage mentors in activities with students not in the school system, and adults in the broader community. Despite some identified challenges, the mentoring program was perceived to be successful in engaging remote Aboriginal children in school and developing future career aspirations. 相似文献

Analysis of the university careers of students who are training to become primary school teachers has shown that a certain number have real difficulty in passing examinations in the scientific and methodological fields. This paper uses both objective and subjective data to analyse the levels of competence in this cultural field, and the propensity towards certain disciplines. Competence in scientific subjects among these students varies considerably, but the greatest concern is a widespread negative attitude towards the quantitative sciences. To transform this approach the way in which these are taught to future teachers requires considerably improvement, by means of projects and programs which take into consideration awareness of this background, that is the attitude of “fighting shy”, from both cognitive and affective viewpoints. 相似文献

This article is a report of a Community Development Project currently being run by the Centre for Studies and Development in Environmental Education (CEDEA), at the National Institute for Amazon Research (INPA) in Manaus, Amazonas, Brazil. The Centre was inaugurated 3 years ago as part of an attempt to change the Institute's direction, from that of carrying out research for the scientific community to one that integrates research with sustainable development and social needs. CEDEA's team members embarked on a participatory community project, INPA and Society, that was developed with a community near the Institute. This is an urban community with economic, social, cultural and environmental problems that the project aims to approach. INPA and Society is divided into several projects, one of which is Women in Action. This is a report about the challenges that Women in Action has produced for both the Institute and the Centre. It also discusses the results that are being achieved, while commenting on the difficulties that have been confronted and how these could possibly be avoided by other groups. 相似文献

Rugby Union scrumming puts the spine under a high degree of loading. The aim of the current study was to determine how sagittal hip range of motion and quadriceps fatigue influence force output, spinal posture, and activation of the trunk and quadriceps muscles in rugby scrumming. Measures of sagittal hip flexion/extension range of motion were collected from 16 male varsity and club first XV level participants. Sagittal spine motion (electromagnetic motion capture), trunk and quadriceps activation (electromyography), and applied horizontal compressive force (force plate) were measured during individual machine scrumming. Participants performed a 5-trial scrum block involving 5?s of contact with 1–2?min recovery between each trial. They then performed a fatiguing protocol (wall sit to failure) and immediately returned to the scrum machine to perform another five trials. Though there was no significant influence of fatigue on the horizontal compressive force applied during contact (P?=?.83), there was a 52% increase in cervical flexion (P?P?P?相似文献

In this project, we worked in partnership with school teachers who are frequent users of experimental kits available for loan to schools using the historical-investigative approach. The original kits bring a traditional approach to experimentation, without the presence of the history of science. We developed and implemented new guides to the kits, without changing their materials and instruments. Design-based research supports the development methodology; the school science topics covered in this paper are Joseph Black’s studies on latent and specific heat. Although some of the challenges faced in the implementation of historical-investigative approach are known and well-documented, the present article addresses teachers’ perspectives and some of the problems they faced in the implementation process, most of them related to school and teacher working conditions. Even though this is a case study with a small number of schools and teachers, it is possible to say that there is a huge gap to overcome before the historical-investigative approach can be implemented in large scale.

IntroductionThe study aimed to investigate the prevalence and titres of anti-SARS-CoV-2 antibodies in children treated at the Children’s Hospital Zagreb in the first and the second wave of the COVID-19 pandemic. Statistical significance of difference at two time points was done to determine how restrictive epidemiological measures and exposure of children to COVID-19 infection affect this prevalence in different age groups.Materials and methodsAt the first time point (13th to 29th May 2020), 240 samples and in second time point (24th October to 23rd November 2020), 308 serum samples were tested for anti-SARS-CoV-2 antibodies by enzyme-linked immunosorbent assay (ELISA) and electrochemiluminescence immunoassay (ECLIA). Confirmation of results and titre determination was done using virus micro-neutralization test. Subjects were divided according to gender, age and epidemiological history.ResultsSeroprevalence of anti-SARS-CoV-2 antibodies differs significantly in two time points (P = 0.010). In first time point 2.9% of seropositive children were determined and in second time point 8.4%. Statistically significant difference (P = 0.007) of seroprevalence between two time points was found only in a group of children aged 11-19 years. At the first time point, all seropositive children were asymptomatic with titre < 8. At the second time point, 69.2% seropositive children were asymptomatic with titre ≥ 8.ConclusionsThe prevalence of anti-SARS-CoV-2 antibodies was significantly lower at the first time point than at the second time point. Values of virus micro-neutralization test showed that low titre in asymptomatic children was not protective at the first time point but in second time point all seropositive children had protective titre of anti-SARS-CoV-2 antibodies. 相似文献

Eosinophil cationic protein (ECP) is a heterogeneous molecule originating from activated eosinophil granulocytes. Biological activity and the cellular content of ECP are determined by genetic and posttranslational factors. Several single nucleotide polymorphisms (SNPs) in human ECP gene (RNASE3) have been described so far. ECP is a mediator in host immune response to parasites, bacteria and viruses. By its cytotoxic and non-cytotoxic activity, ECP may also cause side-effects in the host's own tissues. The largest number of clinical studies is focused on the role of ECP in eosinophil-related disorders, particularly in asthma. Although present in numerous body fluids, difficult bioavailability of biological material, invasive sampling methods and complex sample management prior to ECP level determination are the reasons that serum is most commonly used in routine laboratory practice. As numerous biological and methodological preanalytical factors (the type of collection test-tube, temperature and duration of blood clotting, centrifugation, hemolysis) may affect test result, the sample for serum ECP determination should be collected under standardized conditions. Regarding interpretation of results, it is necessary, along with absolute ECP concentration values, to monitor changes in ECP concentration during the duration of disease or after implemented therapy, and interpret ECP test result in combination with other laboratory and clinical findings. Rational approach to selection of new tests is indeed one of important requirements that medical workers meet today. To enable them to determine the clinical significance of ECP with better certainty, further studies on a large number of specific patient groups are needed. 相似文献

High‐quality early childhood education has been shown to improve school outcomes in several developing and developed nations. The history of policy around pre‐school education in Costa Rica is described as background to presenting cross‐sectional data on the emergent literacy skills of low‐income Costa Rican children in kindergarten, 1st and 2nd grade from six schools (n?=?335). These data suggest that Costa Rican children show rather limited emergent literacy knowledge at the end of kindergarten. In addition, instruction in nine kindergarten classrooms is described and evaluated in order to provide vignettes of educational practice. The need for developmentally appropriate practice around emergent literacy skills and articulation with 1st grade is discussed and appropriate professional development is called for. 相似文献
