ABSTRACT A controversial set of elite jewels assumed to be of early medieval period, recovered in 1937–1938 from a burial site in Matzhausen (northeastern Bavaria) was investigated to determine their technological coherency as well as their authenticity. The discovery of these jewels was exploited by German nationalists to argue that the material culture observed in Bohemia and Moravia in the ninth century had Germanic roots. The circumstances of their discovery, however, remain unclear. Research in archives demonstrated the involvement of the SS Ahnenerbe organisation in the recovery of the jewels. Are these jewels authentic or are they forgeries manufactured or modified by a modern craftsman to serve German expansionist nationalism? Three jewels recovered in the grave – a gombik (hollow spherical pendant), an earring with chainlet, and a zoomorphic figurine – were investigated using scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDX), X-radiography, and stereomicroscopy. The investigation revealed a very heterogeneous set of objects with respect to technology and state of preservation. It also uncovered repairs and past invasive interventions involving modern metal and solder. Comparison with similar types of jewels from Bohemia and Moravia points to important differences in construction and technology, which confirms the uniqueness of this set of objects and casts suspicion on their authenticity. 相似文献

Assessment of educational effectiveness provides vitally important feedback to Institutions of Higher Education. It also provides
important information to external stakeholders, such as prospective students, parents, governmental and local regulatory entities,
professional and regional accrediting organizations, and representatives of the workforce. However, selecting appropriate
indicators of educational effectiveness of programs and institutions is a difficult task, especially when criteria of effectiveness
are not well defined. This article proposes a comprehensive and systematic approach to aligning criteria for educational effectiveness
with specific indicators of achievement of these criteria by adapting a popular organizational training evaluation framework,
the Kirkpatrick’s four level model of training criteria (Kirkpatrick 1959; 1976; 1996), to assessment in Higher Education. The four level model consists of reaction, learning, behavior and results criteria. Adaptation of this model to Higher Education helps to clarify the criteria and create plans for assessment of educational
outcomes in which specific instruments and indicators are linked to corresponding criteria. This provides a rich context for
understanding the role of various indicators in the overall mosaic of assessment. It also provides Institutions of Higher
Education rich and multilevel feedback regarding the effectiveness of their effort to serve their multiple stakeholders. The
importance of such feedback is contextualized both in the reality of stakeholder pressures and in theoretical understanding
of colleges and universities as open systems according to the systems theory (Katz and Kahn 1966). Although the focus of this article is on Higher Education, core principles and ideas will be applicable to different types
and levels of educational programs. 相似文献

This study examined the perception of children’s internalising and externalising behaviours by Russian teachers, mothers and school psychologists. The participants rated their agreement about the causes, seriousness and recommended interventions for the problem behaviour of a fictitious girl/boy described in two vignettes. Mixed ANOVAs indicated that all the respondents attributed externalising behaviours to social causes to a greater degree than internalising behaviours. Compared to mothers and psychologists, teachers perceived both types of behaviours as more serious; however, they downplayed their own role in the child’s problems. Psychological help was more popular among school psychologists than among mothers. Correlational analyses demonstrated problem- and respondent-specific associations between casual attributions and recommended interventions. Implications for educational practice are discussed. 相似文献

The safety and efficiency of air traffic are significantly affected by adverse weather. This holds especially in terminal maneuvering areas (TMA) where, in addition to the impact of weather itself, potential weather avoidance routes are strongly restricted by air traffic regulations. A weather avoidance model DIVMET has been developed which proposes a route through a field of developing thunderstorms. Air traffic control regulations have not been included in it at this stage. DIVMET was applied to the TMA of Hong Kong International Airport as air traffic control (ATC) there has become interested in improving the controller’s work load, especially for managing incoming traffic by avoidance route simulations. Although visual inspection of simulated avoidance routes by ATC was satisfactory, a quantitative validation of simulated with real observed routes was also carried out. Two real adverse weather situations with thunderstorms within the TMA of Hong Kong and with heavily distorted traffic were chosen. The main objective prior to any validation, however, was to identify routes which are solely impacted by weather but do not show any signs of regulation. Route selection was done on the base of flight position data. Landing flights were selected and deviations from standard approach routes were analyzed. As a result, the majority of 272 flights were found to be affected by both weather and regulations (60%), highlighting the challenge for air traffic controllers to manage landing traffic under adverse weather conditions safely and efficiently. Only a few weather-affected flights (7%) were not regulated and could be used for validation. DIVMET simulation routes were presented to local air traffic controllers who confirmed them as potential and realistic avoidance routes. DIVMET weather avoidance route simulations within a TMA appear to be helpful but further model development has to incorporate traffic regulations, to include holdings, short-cuts, and slow-downs. 相似文献

Do classroom exemplars promote the application of principles in teacher education? A comparison of videos,animations, and narratives 总被引：2，自引：1，他引：1

Students learned about teaching principles with a multimedia program that either did not include a classroom exemplar illustrating
how to apply the learned principles to the teaching practice (control group) or included a classroom exemplar in video, animation,
or text format. Across two experiments, video and animation groups reported more favorable attitudes towards learning and
were better able to apply the learned principles than the control group. Text and control groups did not differ in their learning
or attitudes towards learning, suggesting that format is an important factor in determining the effectiveness of classroom
exemplars as pedagogical tools for teacher education. Results encourage the use of visual classroom exemplars to promote the
application of theory into practice. 相似文献

Given the growing interest in retrieval practice among educators, it is valuable to know when retrieval practice does and does not improve student learning—particularly for educators who have limited classroom time and resources. In this literature review, we developed a narrow operational definition for “classroom research” compared to previous reviews of the literature. We screened nearly 2000 abstracts and systematically coded 50 experiments to establish a clearer picture of benefits from retrieval practice in real world educational settings. Our review yielded 49 effect sizes and a total n?=?5374, the majority of which (57%) revealed medium or large benefits from retrieval practice. We found that retrieval practice improved learning for a variety of education levels, content areas, experimental designs, final test delays, retrieval and final test formats, and timing of retrieval practice and feedback; however, only 6% of experiments were conducted in non-WEIRD countries. Based on our review of the literature, we make eight recommendations for future research and provide educators with a better understanding of the robust benefits of retrieval practice across a range of school and classroom settings.

ABSTRACTIn the text, we will try to give an account of the experience of collaboration in a Public Ethics course in the degree course in Pedagogical Sciences at the University of Verona. The course in Public Ethics has had, as its main theme, the reflection on the distinction between public and private. We will begin with consider the national context and then the one of Verona, characterised on one side by a strong feminist presence, on the other from being inserted into a cultural environment with an equally strong presence of the Catholic and conservative. After investigating this peculiar coexistence, we would like to highlight our reactions and those of the students. In particular, we will focus on emerging resistances and on amazement in front of the issues and the history of feminism by many male and female students. Finally, we use the points that emerged during the course to rethink our position as feminists and as researchers. 相似文献

This study focuses on the changes in properties of cellulose-based paper, which can take place as a consequence of its contamination by dust particles. The PM1 (fine) and PM10 (coarse) fractions of the dust particles from archival repositories were collected on cellulose filters Whatman 41, polytetrafluorethylene, and quartz filters. The latter two types of samples were subsequently analyzed gravimetrically, with ion chromatography, PIXE, and the thermal–optical transmission method, giving mass, ionic, elemental carbon, and organic carbon concentrations. After artificial aging, the viscosity-average degree of polymerization of cellulose (DPv) was measured. It was confirmed that cellulose-based paper can undergo substantial changes when contaminated by dust particles and artificially aged. The decrease of the DPv of cellulose showed a negative correlation with the deposited mass of sulfate ions in the dust particles. Considering the particle size fraction, the results suggest the decisive importance of the fine (PM1) particles. The results provide better understanding of how particulate matter contributes to the chemical degradation of cellulose-based paper. Such knowledge is of importance when considering appropriate conservation measures in archives, libraries, and galleries. 相似文献
