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   

Market orientation in managing relationships with multiple constituencies of Croatian higher education   总被引：1，自引：0，他引：1  

Jurica Pavičić  Nikša Alfirević  Zoran Mihanović 《Higher Education》2009,57(2):191-207

In this paper, market orientation in Croatian higher education (HE) is discussed within the context of stakeholder-oriented management. Drawing on existing studies, the ‘classical’ empirical model, describing the market orientation of generic nonprofit organisations, has been adapted to the contingencies of the Croatian HE sector. Empirical testing of the model, based on primary data drawn from the majority of public institutions of higher learning in the country, reveals inadequate market orientation toward the relevant stakeholders. Although social market orientation currently does not exist in Croatian HE institutions, the empirical results confirm that it might be possible to initiate a ‘virtuous circle’, in which relevant market orientation and stakeholder management practices, directed toward one or other of the stakeholders, simultaneously enhance orientation toward the other stakeholders. Unfortunately, the current situation in HE is not satisfactory, which could hinder the implementation of development of knowledge society in Croatia.

Mobilising funds of identity in and out of school   总被引：1，自引：0，他引：1  

David Subero  Ellen Vujasinović 《Cambridge Journal of Education》2017,47(2):247-263

Learning happens through participation in formal community events and informal community activities. However, learning activities that take place in and out of school are often not mutually recognised. Funds of knowledge projects foster new ways of exchanging learning experiences in and out of school. Funds of identity can be uncovered by teachers through the collection of artefacts, interests and practices that are valuable to children. Specifically, videos, photographs, self-portraits, bilingual texts, diaries or ‘shoeboxes of significant items’ are some of the resources that can be used to make a learner’s funds of identity more visible and tangible in the classroom. The main aim of this paper is to illustrate a number of resources and strategies that help to identify and mobilise funds of identity. These funds of identity are integral for educators in order to develop meaningful and contextualised lessons.  相似文献   

Science, the public, and social elites: how the general public, scientists, top politicians and managers perceive science     

Prpić K 《Public understanding of science (Bristol, England)》2011,20(6):733-750

This paper finds that the Croatian public's and the social elites' perceptions of science are a mixture of scientific and technological optimism, of the tendency to absolve science of social responsibility, of skepticism about the social effects of science, and of cognitive optimism and skepticism. However, perceptions differ significantly according to the different social roles and the wider value system of the observed groups. The survey data show some key similarities, as well as certain specificities in the configuration of the types of views of the four groups--the public, scientists, politicians and managers. The results suggest that the well-known typology of the four cultures reveals some of the ideologies of the key actors of scientific and technological policy. The greatest social, primarily educational and socio-spatial, differentiation of the perceptions of science was found in the general public.  相似文献

Possibility thinking: culminative studies of an evidence-based concept driving creativity?     

Anna Craft  Teresa Cremin  Pamela Burnard  Tatjana Dragovic  Kerry Chappell 《Education 3-13》2013,41(5):538-556

The authors have, for some years, studied the concept of ‘possibility thinking’ (PT), or ‘what if’ and ‘as if’ thinking in children aged 3–11, which generates novelty – and the pedagogical strategies which foster it. They have argued, on the basis of previous qualitative studies, that ‘PT’ is at the core of creativity in education. Having begun as a conceptual study for 7 years, this team has undertaken empirical studies of PT in classrooms. This paper discusses findings from the third phase of empirical work focusing on 9- to 11-year olds. The particular research question addressed here is ‘What characterises possibility thinking as manifest in the learning engagement of children aged 9–11?’. In a small-scale qualitative study, involving co-participation with teachers, the paper features episode analysis of naturalistic video data featuring children aged 9–11 in two schools. It focuses on PT evidenced by children engaged in a range of classroom activities, some established as individual activities and others as group work. The study reveals some features of PT in both sites (question-posing [Q-P], question-responding [Q-R], self-determination, intentional action, development, being imaginative, play/playfulness, immersion and innovation) to differing degrees of strength. Risk-taking was absent in both and a new feature, collaboration, evident in both. Differences were documented in how Q-P and Q-R manifest, compared with earlier studies with younger children. This study seeks to make an evidence-based contribution to the characterisation of PT as driving creativity in the classroom, with implications for research and practice.  相似文献   

The attitudes of teachers towards inclusive education in Vojvodina     

Dragana Galović  Nenad Glumbić 《International Journal of Inclusive Education》2013,17(12):1262-1282

The aim of this study was to examine the attitudes of preschool, primary, secondary and high school teachers towards inclusive education of children with special educational needs. In addition, the study established the correlation between these attitudes and gender, education level, teaching experience, formal training in the special education field, and the duration and quality of work experience with children with special education needs. The sample comprised 322 teachers from the Serbian province of Vojvodina. The My Thinking about Inclusion Scale (Stoiber, K. C., M. Gettinger, and D. Goetz. 1998. “Exploring Factors Influencing Parents' and Early Childhood Practitioners Beliefs about Inclusion.” Early Childhood Research Quarterly 13 (1): 107–131) was used. The results show that, in general, the participants held neutral attitudes towards inclusive education and more positive expectations regarding the outcomes of inclusion. This study also emphasised teaching performance in an inclusive class as a subject of great concern. The high school and preschool teachers as well as the teachers with previous positive experience with working in an inclusive environment reported more positive attitudes towards inclusive education than those from primary and secondary schools and those with negative experiences with the implementation of inclusive practices.  相似文献

Effects of rule changes on physical demands and shot characteristics of elite-standard men’s squash and implications for training     

Stafford Murray  Mike D. Hughes  Janez Perš  Rok Mandeljc  Goran Vučković 《Journal of sports sciences》2016,34(23):2170-2174

The physical demands and rally characteristics of elite-standard men’s squash have not been well documented since recent rule changes (scoring and tin height). This information is needed to design optimal training drills for physical conditioning provided here based on an analysis of movement and shot information. Matches at the 2010 (n = 14) and 2011 (n = 27) Rowe British Grand Prix were analysed. Rallies were split into four ball-in-play duration categories using the 25th (short), 75th (medium), 95th percentiles (long) and maximum values. Cohen’s d and chi-squared tests of independence evaluated effects of rally and rule changes on patterns of play. The proportion of long, middle and short shots was related to the duration of the rally with more shots played in the middle and front of the court in short rallies (phi = 0.12). The frequencies of shots played from different areas of the court have not changed after the adoption of new rules but there is less time available to return shots that reflect the attacking nature of match play for elite-standard men players. Aspiring and current elite-standard players need to condition themselves to improve their ability to cope with these demands using the ghosting patterns presented that mimic demands of modern match play.  相似文献
