Objective
This study was aimed at assessing the dynamics of vitronectin (VN), laminin (LN), and heparan sulfate/heparin (HS/HP) content changes during experimental burn healing.Methods
VN, LN, and HS/HP were isolated and purified from normal and injured skin of domestic pigs, on the 3rd, 5th, 10th, 15th, and 21st days following thermal damage. The wounds were treated with apitherapeutic agent (propolis), silver sulfadiazine (SSD), physiological salt solution, and propolis vehicle. VN and LN were quantified using an immunoenzymatic assay and HS/HP was estimated by densitometric analysis.Results
Propolis treatment stimulated significant increases in VN, LN, and HS/HP contents during the initial phase of study, followed by a reduction in the estimated extracellular matrix molecules. Similar patterns, although less extreme, were observed after treatment with SSD.Conclusions
The beneficial effects of propolis on experimental wounds make it a potential apitherapeutic agent in topical burn management. 相似文献102.

We investigated how adolescents (sixth-graders, N = 357) morally evaluated hypothetical bullying and defending protagonists and whether these evaluations related to behavior in bullying as nominated by peers. Exploratory factor analysis (EFA) resulted in four factors for the evaluation of the hypothetical bullies: Evil soul, Contempt, Cowardice, and Deviance, and five factors for the evaluation of the hypothetical defender: General admiration, Courage, Cool, Empathic care, and Fair justice. Corresponding scales were constructed. The findings showed that bullying positively correlated with evaluating the hypothetical bullies using Cowardice while victimization positively correlated with evaluating the hypothetical defender in terms of General admiration, Empathic care, and Fair justice. MANOVA for each of the two sets of the evaluative scales indicated that behavioral status (bully, victim, defender, or uninvolved) had a significant effect on the moral evaluation of hypothetical bullies, and no significant effect on the moral evaluation of the hypothetical defender. 相似文献

AbstractThis article reflects on the successes and failures of a new Philosophy and Ethics course in a low socioeconomic context in Perth, Western Australia, with the eventual demise of the subject in the school at the end of 2010. We frame this reflection within Deleuzian notions of geophilosophy to advocate for a Philosophy and Ethics that is informed by nomadic thought, as this offers a critical freedom for students to transform themselves and their society and suggests practical ways both of overcoming the prejudices which led to its demise and of student reluctance to engage in open discussion in class. We consider the demise of the course a ‘missed opportunity’ because it had so much potential to be transformative of student subjectivities in schools. 相似文献

This self-ethnography complements the other articles in this special issue by spotlighting a set of key challenges facing international research teams. The study is focused on the relationship between information and communication technology (ICT)-based collaboration and research team dynamics. Our diverse team, drawn from researchers in five countries and three projects, argues that an ironic casualty of the powerful, global phenomena we study, is a lack of insight into what happens to generic research team dynamics, when groups are ‘stretched’ in terms of geographical distance, generations, cultural beliefs, values and norms, as well as disciplinary/specialist traditions. Good intentions are not sufficient to cope with these challenges. This is because of the emerging complexity inherent in many types of international, interdisciplinary fields of study and the complexity of the career trajectories needed to make these studies a reality. Our study underlines that there are no beliefs, values, norms and practices linked to research team dynamics, that hold across the current territory, generations, disciplines, cultures, organizations and individuals leading and conducting comparative studies—and even less reflection on the implications of this fact. Compounding this lack of awareness is a less-than-perfect understanding of the way in which ICT-based collaboration bears on research team dynamics. We assert that a holistic, critical, long-term approach to emerging insights into the global division of academic labor, serves our field better than folk psychology or the methodological parochialism that sustains convention at the expense of creativity. Careful consideration of emergent processes, relationships and linkages that explain how short-term cooperation—within projects—begins to make sense—over careers—illuminates key focal points, which, in turn qualitatively illuminates the way forward concerning conceptualization and problematization of our practice; and novel methodological routes available for those interested in attaining better outcomes, over the long term. 相似文献

Student evaluation of teaching (SET) is now common practice across higher education, with the results used for both course improvement and quality assurance purposes. While much research has examined the validity of SETs for measuring teaching quality, few studies have investigated the factors that influence student participation in the SET process. This study aimed to address this deficit through the analysis of an SET respondent pool at a large Canadian research-intensive university. The findings were largely consistent with available research (showing influence of student gender, age, specialisation area and final grade on SET completion). However, the study also identified additional influential course-specific factors such as term of study, course year level and course type as statistically significant. Collectively, such findings point to substantively significant patterns of bias in the characteristics of the respondent pool. Further research is needed to specify and quantify the impact (if any) on SET scores. We conclude, however, by recommending that such bias does not invalidate SET implementation, but instead should be embraced and reported within standard institutional practice, allowing better understanding of feedback received, and driving future efforts at recruiting student respondents. 相似文献

This paper presents a nonlinear dynamic model for simulation and analysis of a kind of parametrically excited vibration of
stay cable caused by support motion in cable-stayed bridges. The sag, inclination angle of the stay cable are considered in
the model, based on which, the oscillation mechanism and dynamic response characteristics of this kind of vibration are analyzed
through numerical, calculation. It is noted that parametrically excited oscillation of a stay cable with certain, sag, inclination
angle and initial static tension force may occur in cable-stayed bridges due to deck vibration under the condition that the
natural frequency of a cable approaches to about half of the, first model frequency of the bridge deck system. A new vibration
control system installed on the cable anchorage is proposed as a possible damping system to suppress, the cable parametric
oscillation. The numerical calculation results showed that with the use of this damping system, the cable oscillation due
to the vibration of the deck and/or towers will be considerably reduced.

The aim of this study was to explore comprehension monitoring and perceived use of reading strategies as factors of reading comprehension. Participants were elementary school students from the fifth to the eighth grade. Error correction and text sensitivity tasks from the Metacomprehension test (Pazzaglia, De Beni, &; Cristante, 1994). and the cloze-task were used as measures of comprehension monitoring during reading. A Strategic reading questionnaire (Koli?-Vehovec &; Baj?anski, 2001b) was applied as a measure of perceived use of strategies during reading. Girls had better results than boys on text comprehension, all measures of comprehension monitoring, as well as on the Strategic reading questionnaire. Significant developmental improvements in comprehension monitoring occurred after the fifth grade and between the sixth and the eighth grade. A similar change was evident in reading comprehension. All measures of comprehension monitoring were significantly related to text comprehension in all age groups. However, perceived use of reading strategies was significantly related to reading comprehension only in eighth-grade students. 相似文献

ABSTRACTEfforts to reach gender equality in education in Finland have been extensive. Both teacher education and policy documents for schools have focused on gender equality and gender-neutral treatment of students. The aim of this study is to explore if and how these efforts are manifested in upper secondary school teachers’ and study counsellors’ perceptions of students’ self-belief, academic emotions, study habits and behaviour at school. Twenty-three interviews were conducted and analysed qualitatively through inductive content analysis. The results revealed that teachers and study counsellors perceive that girls’ low self-belief and high achievement expectations affected their academic performance, while boys’ insecurity or need for support was rarely mentioned. The teachers ascribed the students several gender-stereotypical attributes: girls were perceived as diligent and hard-working while boys were perceived as being indifferent towards school and achievements. The implications of these results for students’ self-belief and for teacher education are discussed. 相似文献
