In this paper, we examine the meaning of conversing with pedagogical agents. Previous research has focused on examining cause and effect relationships, failing to take into account the meaning of the experiences individuals have when holding a dialogue with conversational agents for educational purposes. To understand these experiences, we have conducted a phenomenological examination of what it means to converse with a pedagogical agent. In phenomenological terms, findings suggest the experience is complex, engrossing, virtual yet real, human‐like, and social. Implications for the future design, implementation, and research of conversational agents in educational and other settings are discussed. 相似文献

Thrombotic risk factors may contribute to premature coronary artery disease (CAD), in addition to the conventional risk factors. There is paucity of data on studies evaluating the role of thrombotic factors in premature CAD in Indian patients. Thus a case–control study was performed to evaluate the role of thrombotic and atherogenic factors in young patients with angiographically proven CAD who are on treatment with statins and anti-platelet drugs. 152 patients (≤55 years) with angiographically proven CAD and 102 asymptomatic controls were recruited. Clinical and biochemical data were obtained in both groups. Blood levels of thrombotic factors-fibrinogen, antithrombin-III, tissue-plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), von-Willebrand factor (v-WF), lipoprotein(a) [Lp(a)] and homocysteine were analyzed. Patients had high levels of conventional CAD risk factors (diabetes mellitus, smoking, hypertension, dyslipidemia and positive family history) compared to controls. Logistic regression analysis revealed that low antithrombin-III (odds ratio/OR 11.2; 95 % confidence interval/CI 2.29–54.01), high fibrinogen (OR 6.04; 95 % CI 1.09–33.21) and high Lp(a) (OR 4.54; 95 % CI 0.92–22.56), as important, independent risk factors in patients. PAI-1(OR 0.15; 95 % CI 0.03–0.69) levels were significantly lower in patients. But other thrombotic risk factors studied (t-PA, v-WF and homocysteine) were comparable among patients and controls. The treatment using statins and anti-platelet drugs might be contributing to the control of some of the thrombotic risk factors. The strategies aiming at lowering the levels of thrombotic risk factors along with conventional risk factors may be useful in primary and secondary prevention of CAD. 相似文献

Although there is increasing interest in promoting mental health and wellbeing within education, to date, the voices of young people appear to have been almost completely overlooked in the development of school-based mental health practices. This is despite increasing focus on young people’s participation; and the fact that young people may be best positioned to understand the pressures of contemporary society. This paper, co-authored by educational psychologists (EPs), school students and the school vice-principal, documents the development of a student-led mental health initiative within a high-achieving girls’ grammar school, led by students aged 12–18. Following EP input, the students devised a whole-school, student-friendly mental health strategy with the support of the EPs and senior school staff. As the project progressed, it became evident that applying even carefully selected adult mental health models to school contexts might not be appropriate; instead the students advocated for young person-friendly, innovative, contemporary and creative ways of communicating information about mental health, which avoided stigma. The students involved were well-placed to identify environmental stressors and to disseminate their strategy. The authors conclude that mental health planning in schools should encourage greater student participation, show caution over applying adult mental health models and promote greater use of technology or visual resources. 相似文献

Studies have acknowledged children not as climate change victims only, but also as climate change actors. However, only a few have addressed the preparatory stages of children as climate change actors. However, the few studies that addressed these preparatory stages gave attention only to the roles of schools and government agencies without adequate attention to that of parents. This article therefore attempts to discuss the role of eco-parenting in building mitigation and adaptation capacities in children. Relying on the authoritative parenting model, the article avers that eco-parenting can have significant effects on children's ability to protect the environment, mitigate, and adapt to climate change impacts. 相似文献
