A great number of Central Asian wall paintings, archeological materials, architectural fragments, and textiles, as well as painting fragments on silk and paper, make up the so called Turfan Collection at the Asian Art Museum in Berlin. The largest part of the collection comes from the Kucha region, a very important cultural center in the third to ninth centuries. Between 1902 and 1914, four German expeditions traveled along the northern Silk Road. During these expeditions, wall paintings were detached from their original settings in Buddhist cave complexes. This paper reports a technical study of a wall painting, existing in eight fragments, from the Buddhist cave no. 40 (Ritterhöhle). Its original painted surface is soot blackened and largely illegible. Grünwedel, leader of the first and third expeditions, described the almost complete destruction of the rediscovered temple complex and evidence of fire damage. The aim of this case study is to identify the materials used for the wall paintings. Furthermore, soot deposits as well as materials from conservation interventions were of interest. Non-invasive analyses were preferred but a limited number of samples were taken to provide more precise information on the painting technique. By employing optical and scanning electron microscopy, energy dispersive X-ray spectroscopy, micro X-ray fluorescence spectroscopy, X-ray diffraction analysis, and Raman spectroscopy, a layer sequence of earthen render, a ground layer made of gypsum, and a paint layer containing a variety of inorganic pigments were identified.  相似文献   

Context-sensitive regularities in English vowel spelling     

Mark Aronoff  Eric Koch 《Reading and writing》1996,8(3):251-265

The predictive value of rime spellings in English was compared directly to other types of regularities beyond the level of the single letter. A computer-assisted analysis of a list of twenty-four thousand written words, each paired with its corresponding pronunciation, reveals that only a small number of rime spellings are highly regular in their pronunciations. The conventional division of vowel letter pronunciations into short and long in closed and open written syllables is the most reliable key to English pronunciation. Our findings support the notion that English spelling is based at least in part on syllable structure. In addition, prefixes and suffixes provide very reliable clues to pronunciation, which suggests that their regularity should be exploited in the teaching of reading.  相似文献   

Understanding Leadership in Major Sporting Events: The Case of the 2005 World Aquatics Championships     

Milena M. Parent  Denise Olver  Benoit Séguin 《Sport Management Review》2009,12(3):167-184

The purpose of this paper was to begin understanding leadership within a major sporting event. A case study of the 2005 Fédération Internationale de Natation (FINA) World Aquatics Championships was built by means of interviews and archival material, using a multi-stakeholder perspective. Findings highlighted that core elements of upper-management level leadership in events were best described by the multiple-linkage leadership theory, which includes task commitment, ability and role clarity, work organization, cooperation and mutual trust, resources and support, and external coordination as the six intervening variables. While charismatic and transformational leadership styles surfaced as contributing to the overall success of an event, the multiple-linkage leadership theory offered a more comprehensive understanding of leadership in major sporting events from a multi-stakeholder perspective.  相似文献   

Evaluating the feasibility of remotely administered curriculum-based measurement for students with autism: A pilot study

Students with autism may struggle to develop the academic skills necessary for success in school and beyond. Understanding and improving academic skills performance requires appropriate measurement approaches. One such option that has been minimally studied with students with autism is curriculum-based measurement (CBM). Coinciding with the need to study different approaches to academic skills measurement for students with autism was the global pandemic which forced a shift to remote service delivery with little warning. While some autistic students struggled with this shift, others thrived, raising questions about how to further support students with autism in virtual formats. The purpose of this study was to examine the feasibility of using remotely administered CBM for autistic students by studying both the practicality and acceptability of this approach. Five students with autism (Grades 2–5) participated in this pilot study, completing reading, math, and writing CBMs at three time points. Student behavior and assessor fidelity were collected to examine practicality; assessor ratings of usability provided insight regarding the acceptability of the approach. Results indicated that remotely administered CBM is feasible for some students with autism: all participants completed the study tasks with minimal behavioral difficulties, and assessor ratings of acceptability were high.  相似文献   

Creatine kinase activity weakly correlates to volume completed following upper body resistance exercise     

Machado M  Willardson JM  Silva DR  Frigulha IC  Koch AJ  Souza SC 《Research quarterly for exercise and sport》2012,83(2):276-281

In the current study, we examined the relationship between serum creatine kinase (CK) activity following upper body resistance exercise with a 1- or 3-min rest between sets. Twenty men performed two sessions, each consisting of four sets with a 10-repetition maximum load. The results demonstrated significantly greater volume for the 3-min condition (M = 4156 kg, SD = 867, for 3 min; vs. M = 3503 kg SD = 759, for 1 min; p < .001), with no significant differences in delta CK activity between conditions (p = .574). Nevertheless, there was a weak correlation between the delta CK activity and total volume of exercise completed (r = .55 with a 1-min rest, and r = .45 with a 3-min rest). Therefore, the volume following upper body resistance exercise correlates weakly with serum CK levels, irrespective of rest interval length between sets.  相似文献   

“I never thought this could be for me”: aspirational capital,identities, and political engagement among first-generation college students in São Paulo     

Charles H. Klein  Milena Mateuzi Carmo 《International Studies in Sociology of Education》2019,28(3-4):259-278

ABSTRACT

Today, young adults from lower-income backgrounds are pursuing educational trajectories that would have been distant dreams for their parents. In many Global South countries, this expansion has followed a neoliberal logic in which private universities purport to provide students skills and increased earning capacity, and employers the necessary human capital to compete in global markets. This article examines these processes in Brazil, where federal policies have contributed to a dramatic growth in private, for-profit higher education in recent years. Building on ethnographic research in São Paulo’s expansive peripheries, our analysis examines three inter-related themes: higher education and life aspirations; intersectional identity construction; and political/community engagements. We argue that while neoliberal ideologies and policies are a key component of Brazilian higher education, many first-generation college students actively – and critically – challenge everyday oppressions and create new life possibilities in the context of enduring inequalities.  相似文献   

A mentor’s aid in developing the competences of teacher trainees   总被引：1，自引：0，他引：1  

Milena Valenčič  Janez Vogrinc 《Educational studies》2007,33(4):373-384

The induction period is a very important time in the career of a teacher and has a long‐term influence on the teacher’s professional development, efficacy, job satisfaction and the length of his/her career. One of the key roles in this period is played by the trainee’s mentor. This paper presents the results of the extensive project ‘Partnership of Faculties and Schools’, carried out at the Pedagogical Faculty, University of Ljubljana, with the financial support of the European Social Fund and the Slovenian Ministry of Education, Science and Sport. We studied an induction project involving 361 teacher trainees and 331 mentors. The study reveals the trainees’ expectations towards their mentors and the mentors’ and trainees’ evaluations of how the mentor aids a teacher trainee in developing their competences.  相似文献

Rates of return to investment in education in former Yugoslavia in the 1970s and 1980s by region     

Milena Bevc 《Economics of Education Review》1993,12(4)

The article presents rates of return to investment in education in former Yugoslavia by region — former federal units (republics and autonomous provinces), by level of education, by gender, and for the society and the individual. It has shown some similarities and some differences regarding the observed pattern of the economic efficiency of investment in education in other countries. Some causes for these differences are discussed.  相似文献
