An archaeological excavation has been carried out at Pisa (Italy), unearthing an ancient metallurgical workshop. Since archaeological burnt materials provide important records of direction and intensity of the Earth's magnetic field in the past and they can be used to better improve geomagnetic secular variation curves (SVCs), an archaeomagnetic study has been performed. This small copper-alloy furnace presents a circular concave shape covered with a thin layer of mortar, with some traces of heated clay surrounding the feature that confirms the high temperature reached inside it. Archaeological context dating points to the last firing of the furnace between the last quarter of the 13th century and the first quarter of 14th century AD, when then the metallurgical workshop was transformed in a warehouse. Archaeomagnetic sampling has been performed using the modified Thellier method, by collecting several, large and independently oriented aliquots of heated clay, forming the bottom part of the circular wall of the structure. Laboratory treatments have been conducted at the IGG-CNR ARCHEO_LAB (Pisa, Italy) and at St. Maur Palaeomagnetic laboratory (Paris, France). Analytical measurements of the thermo-remanent magnetization index acquired from the samples have been performed using a large cell induction magnetometer for large samples, and the characteristic remanent magnetization (ChRM) has been successfully isolated after an alternate field demagnetization cleaning procedure for each sample. The final mean archaeomagnetic direction has been calculated at sampling site (D = 6.9°; I = 52.8°; N = 9; k = 305; α95 = 2.6°) following the Fisher Statistics, and it exhibits a perfect agreement with some coeval already published directions obtained from Mt. Arso lava flows, these latter being an important anchor point in the preliminary Italian secular variation curve. Comparison with the preliminary Italian SVC, the French SVC and the SCHA.DIF.3K archaeomagnetic regional model have permitted to define an archaeomagnetic absolute age confirming the conventional archaeological age, underlining the importance of this result into the Italian archaeomagnetic data set. 相似文献

The aim of the article is to present and discuss a study in which Finnish, English and Swedish pupils’ understanding of citizenship education with regard to: (a) political literacy; and (b) attitudes and values was explored. The study was a cross‐national, multiple case study and data were collected through 18 focus group dialogues with 15‐year‐old pupils. Results showed that English pupils were much more well‐informed about rights and responsibilities than their Nordic counterparts and also more skilled rhetorically, but appeared less accustomed to open and confident relationships with adults than the Swedish pupils. Finnish pupils did not seem to be encouraged to talk; instead they kept their thoughts and feelings to themselves. One conclusion, among others, was that the study illuminates conditions for the development of a so‐called key competence – i.e., ‘interpersonal, intercultural, social and civic competence’. 相似文献

The present article focuses on the choices teachers make when teaching Islamic religious education (IRE) in the town of Kisumu, Kenya. The data were collected through interviews with IRE teachers and participant observations in schools that offered IRE during several fieldwork sessions in the period 2003–2006. The fieldwork revealed that the choices teachers made were related to social and religious contexts both inside and outside the school setting and also the more immediate contexts of the teaching–learning situation. Most clearly, the choices were influenced by the fact that IRE is an examinable subject in a larger educational system. This article claims that an alternation between a confessional education into Islam and a more fact‐oriented education about Islam was a strategy used by some teachers balancing between competing demands posed by the educational system, students, parents and the surrounding local society. 相似文献

The general background of this study is an interest in how digital tools contribute to structuring learning activities. The
specific interest is to explore how such tools co-determine students’ reasoning when solving word problems in mathematics,
and what kind of learning that follows. Theoretically the research takes its point of departure in a sociocultural perspective
on the role of cultural tools in thinking, and in a complementary interest in the role of the communicative framing of cognitive
activities. Data have been collected through video documentation of classroom activities in secondary schools where multimedia
tools are integrated into mathematics teaching. The focus of the analysis is on cases where the students encounter some kind
of difficulty. The results show how the tool to a significant degree co-determines the meaning making practices of students.
Thus, it is not a passive element in the situation; rather it invites certain types of activities, for instance iterative
computations that do not necessarily rely on an analysis of the problems to be solved. For long periods of time the students’
activities are framed within the context of the tool, and they do not engage in discussing mathematics at all when solving
the problems. It is argued that both from a practical and theoretical point of view it is important to scrutinize what competences
students develop when using tools of this kind.

Background:Team-sport players have a particularly high injury risk.Although female sex is considered a risk factor,it is still unknown whether female and male team-sport players,in fact,differ in their injury rates.We aimed to compare injury rates between female and male players by systematically reviewing and meta-analyzing injury surveillance studies of both sexes in order to evaluate sex-specific differences in team-sport injuries.Methods:Studies that prospectively collected injury data for high-level female and male players(age≥16 years)in basketball,field hockey,football(soccer),handball,rugby(union and sevens),and volleyball were included.Two reviewers(AZ and ALR)independently assessed study quality and extracted data for overall,match,training,and severe injuries(>28 days’time loss)as well as data regarding injury locations and types.Incidence rate ratios(IRRs)were pooled in a meta-analysis,and meta-regression analysis was performed when 10 or more studies were available.Results:Of 20 studies,9 studies reported injury data from football,3 studies from rugby,3 studies from handball,1 study from basketball,1 study from field hockey,2 studies from volleyball,and 1 study from basketball and field hockey.For overall injuries,the pooled IRR=0.86(95%confidence interval(95%CI):0.76-0.98)indicated significantly more injuries in male than in female players.For injury location,the pooled IRR showed higher injury rates in male athletes than in female athletes for upper extremity,hip/groin,thigh,ande foot injuries.Female players had a significantly higher rate of anterior cruciate ligament injuries(IRR=2.15,95%CI:1.27-3.62)than male players.No significant sex-specific differences in IRR were found for match,training,severe injuries,concussions,or ankle sprains.Conclusion:Our meta-analysis provides evidence for sex-specific differences in the injury rates in team sports.Further epidemiological studies including both sexes in sports other than football are needed in order to strengthen the evidence. 相似文献

Research on induction of newcomers is primarily focused on individual processes, such as acquisition of knowledge and socialization
in order to create a smooth and frictionless entry period. The interest of our research, however, is the processes that happen
on the organizational level. We claim that induction potentially triggers both individual and organizational learning and by drawing on practice-based theory we discuss how the interplay between individual and the organization,
what we call a generative dance, ignites both kinds of learning. We focus on and describe the interplay that takes place in particular induction events and
analyze the “dance” through the lens of learning. The article concludes with a brief discussion about the implications for
practitioners and the challenges and future research prospects we have encountered. We draw on an empirical enquiry in two
organizational settings, a Danish management consulting company and a German retail bank.

ABSTRACTWe assess Mureithi's 2009 documentary, ICYIZERE: hope (Motion Picture, Josiah Films), as a document of representational space and collective memory. We argue that the post-genocide reconciliation workshop represented in the film embodies and constructs a sacred/secular space. The reconciliatory space is produced through (1) negotiations of dialectical tensions between past/present as well as individual/collective memory, and (2) (re)presentations of rehumanization within the workshop whereby participants (and audiences) can (re)interpret the Other. We analyze the rehumanization process in the documentary via identity widening theory (Ellis, D.G., 2006, Transforming conflict: Communication and ethnopolitical conflict. Boulder, CO: Rowman & Littlefield Publishers) and empathetic human interaction. Finally, we detail how the documentary situates participants within a transformative space of negotiated memories of the genocide with current day reconciliation efforts. 相似文献

ABSTRACTThis paper presents an action research project that aimed to increase opportunities for multilingual literacy engagement and identity investment for newly-arrived immigrant students in Norway. A language teacher and a researcher jointly developed a cross-curricular, multilingual module focusing on identity texts written in three languages: English, Norwegian, and each student's home language. Fourteen adolescent students speaking 15 different home languages participated. To assess the effectiveness of the multilingual pedagogical practices, the data collected included a language use questionnaire, student reflection logs, students’ identity texts, lesson plans, and the teacher's notes and reflections. The results suggest that explicit emphasis on including all languages in students’ linguistic repertories can help build inclusive classroom spaces and foster learners’ multilingual identities. 相似文献

Adopting a mixed method design, this paper explores the configuration and evolution of work values of 64 young adults in transition from education to employment. Qualitative analyses point out the existence of four categories of work values: interesting tasks, good relationships, self-fulfillment, and attractive work conditions. Quantitative analyses show that work values are questioned during the school-to-work transition, refined according to the experience of labor market integration, and partially different according to gender, education type, and the quality of the integration process. Consequently, career counseling should integrate a deeper understanding of what clients consider as important in their work lives. 相似文献

Background: From previous research among science teachers it is known that teachers’ attitudes to their subjects affect important aspects of their teaching, including their confidence and the amount of time they spend teaching the subject. In contrast, less is known about technology teachers’ attitudes.
Purpose: Therefore, the aim of this study is to investigate Swedish technology teachers’ attitudes toward their subject, and how these attitudes may be related to background variables.
Sample: Technology teachers in Swedish compulsory schools (n = 1153) responded to a questionnaire about teachers’ attitudes, experiences, and background.
Methods: Exploratory factor analysis was used to inwvestigate attitude dimensions of the questionnaire. Groupings of teachers based on attitudes were identified through cluster analysis, and multinomial logistic regression was performed to investigate the role of teachers’ background variables as predictors for cluster belonging.
Results: Four attitudinal dimensions were identified in the questionnaire, corresponding to distinct components of attitudes. Three teacher clusters were identified among the respondents characterized by positive, negative, and mixed attitudes toward the subject of technology and its teaching, respectively. The most influential predictors of cluster membership were to be qualified for teaching technology, having participated in in-service-training, teaching at a school with a proper overall teaching plan for the subject of technology and teaching at a school with a defined number of teaching hours for the subject.
Conclusions: The results suggest that efforts to increase technology teachers’ qualifications and establishing a fixed number of teaching hours and an overall teaching plan for the subject of technology may yield more positive attitudes among teachers toward technology teaching. In turn, this could improve the status of the subject as well as students’ learning. 相似文献
