Abstract

Advancements in technology have increased preschool children’s access to the Internet. Very little research has been conducted to identify pre-school-aged children’s understandings of the Internet and ramifications of being ‘online’. Without an understanding of children’s thinking about the Internet, it is difficult to provide age- and pedagogically appropriate cyber-safety education. This study developed and pilot-tested an interview schedule that focuses on the Internet thinking and cyber-safety awareness of Australian children aged 4–5 years. The schedule is informed by sociocultural theory, cyber-safety education research and approaches for researching with young children. The schedule shows potential to elicit children’s understandings of the Internet and cyber-safety awareness. Adjustments are required to allow more contextualised responses from children.  相似文献

OBJECTIVE: To examine family risk factors associated with dissociative symptoms among homeless and runaway youth. METHOD: Three hundred and twenty-eight homeless and runaway youth were interviewed using a systematic sampling strategy in metropolitan Seattle. Homeless young people were interviewed on the streets and in shelters by outreach workers in youth service agencies. RESULTS: The current study revealed widespread prevalence of dissociative symptoms among these young people. Multivariate analyses revealed that sexual abuse, physical abuse, and family mental health problems were all positively associated with dissociative symptoms. No gender differences were found for any of the models. CONCLUSIONS: Dissociative behavior is widespread among these youth and may pose a serious mental health concern. Some young people experience numerous stressors, and with few resources and little support available, many may invoke maladaptive strategies such as dissociative behavior to handle such situations, which may in turn be detrimental to their mental health. Unless youth are provided with programs and intervention, the cycle of abuse that they have experienced at home is likely to continue on the street.  相似文献

Early childhood educators currently provide content focused learning opportunities for children in the areas of well-being and environmental education. However, these are usually seen as discrete content areas and educators are challenged with responding to children’s interests in popular-culture inspired food products given these influence their consumption of energy-dense, nutrient-poor and highly packaged food in the early childhood setting. This paper reports preliminary findings from a pilot randomised trial examining the interconnectedness of sustainability, well-being and popular-culture in early childhood education. Planning, assessment documentation and summaries from twenty-four learning experiences implemented by six educators over a six-week period were analysed using a deductive approach. Twenty well-being and environmental education topics were identified and shown to be generated by the educators when considering the children’s ‘funds of knowledge’ on popular-culture inspired food products. We argue that topics derived from children’s engagement with popular-culture may help educators to create an integrated approach to curriculum provision. This may impact child weight and facilitate obesity prevention and environmental sustainability as children create stronger connections between these content areas and their everyday choices and practices.  相似文献

This study attempts to characterise what 7th- and 12th-grade students believe they do not know about artefacts and natural objects, as well as the dependence of what is unknown on a knowledge of these objects. The students were asked to make explicit through questioning what they did not know about a sample of objects. The unknowns generated were categorised according to a scheme based on lexical semantics theory. Two of the categories focused specifically on imprecise unknowns expressed through What is X? questions, and on unknowns concerning functions. The results showed, firstly, that a lower grade level and lower knowledge of a certain class of objects was associated with more imprecise unknowns. Secondly, unknowns about the functions of artefacts were significantly more frequent than unknowns about the functions of natural objects at any of the grade levels. Overall, the results were consistent with the hypothesis of a correspondence between knowledge and unknowns.  相似文献

Over the past ten years there has been a sweeping reform of the courses taught and qualifications awarded by Spanish universities. For that reason, an investigation was launched in 1996–97 at the University of Santiago de Compostela (in Northwest Spain) into the teaching, research and management entailed in four new degree courses: physics (years one to four), agricultural engineering (first and second years), agricultural food-processing technology (years one to three) and pharmacy. This article reports on students' opinions of the reforms in these courses, revealing dissatisfaction with facilities for practical course work, lack of connection with prospective employment, and a call for more information about courses.  相似文献

Objective: To analyze the possible dose-response association between components of sports participation (intensity, volume and previous engagement) and 4-year mortality rates among Brazilian adults.

Methods: 679 males and females (mean age among men = 66.7 ± 9.3 years old and mean age among women = 64.8 ± 8.9 years old) composed the study sample. Sports participation was assessed using Baecke’s questionnaire, which considers intensity, duration and previous engagement. Medical records were used to identify the cause of the death. Cox regression analysis was performed to determine the independent associations of exercise components and mortality.

Results: Participants that reported exercising at moderate-vigorous intensity (Moderate/vigorous: 4.1% versus None/light: 10.3% [p-value = 0.012]; HR = 0.42 [0.1 to 0.94)] and for more than four months (≥4 months: 5.3% versus <4 months: 10.2% [p-value = 0.038]; HR = 0.47 [0.24 to 0.94]) had lower mortality risk. The percentage of survival according to all-cause mortality was significantly higher for participants engaged in sports at moderate-vigorous intensity (p-value = 0.014), as well as for those engaged in sports for periods superior than four months (p-value = 0.036).

Conclusion: We found higher percentage of survival among adults engaged in sports at moderate-vigorous intensity and with at least four months of previous engagement.  相似文献

This article analyses the review, acceptance and publication dates of a sample of 21,890 articles from 326 Ibero-American scientific journals from all subject areas and countries included in the Latindex Catalogue 2.0 and published between 2018 and 2020 (freely available as an open access dataset). The aim is to discover evaluation and publication times. The evaluation process takes a median of 110 days, the publication process, a median of 82 days, and the whole process, a median of 224 days. Statistical differences are found according to periodicity, subject areas, countries, existence of a printed version and article type (Call for Papers or General articles). From the data we find that the delay in publication is longer than publishers themselves report to the DOAJ. STEM areas present the most similarity in publication patterns, having a higher number of evaluation days (Ed) than publication days (Pd); Arts and Humanities present the opposite pattern, with a higher Pd than Ed. In the case of Social Sciences, the times are similar. General articles and Call for Papers articles differ in terms of Ed, but not Pd, indicating that Call for Papers revisions are faster.  相似文献

A random telephone survey (N = 255) of Washington state parents of children between the ages of 2 and 17 assesses parents’ reported patterns of interaction with their children regarding television, along with parental viewing habits and perceptions of television content. Demographic differences in mediation and coviewing patterns, as well as parental attitudes toward television, are explored, and explanations for these differences are considered. It is concluded that education is a weak predictor of mediation levels, single parents do not differ from dual parents in attitudes about television, and that the negative relationship of income to positive mediation and use of television as a babysitter is related more to overall viewing patterns and environmental constraints, rather than to attitudinal differences. It is suggested that demographics hold little value jar explaining why and how parents hold particular attitudes or engage in particular behaviors relevant to television and parenting.  相似文献
