Technical analysis of a Central Asian wall painting detached from a Buddhist cave temple on the northern Silk Road

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.     

The diversity of university disciplinary profiles in research and teaching

Is the ideal of a one-size-fits-all university model—where universities are capable of successfully performing all competencies simultaneously—ever achievable? Has the balance between teaching and research activities grown even more fragile or is such a balance unfeasible? In this paper, we review studies of institutional diversity in higher education and bibliometric analyses. We prose a two-dimensional typology based on diversity in teaching and research by scientific fields. We investigate the diversity in teaching and research, respectively, at the disciplinary level and address whether these primary activities mirror each other. As a measure of mismatch between the two activities, we assess the distribution of students and publications by scientific fields through a clustering analysis. Our study of higher education institutions (HEIs) in Russia reveals that private universities are less diverse both in research and teaching and have high teaching intensity compared to state universities. Expectedly, universities in the rankings have more diverse profiles and they have a higher research intensity.     

Advisory work as assistance in problem-solving — Problem-solving models as basic concepts for advisory work

Abstract

This article summarises some basic concepts of advisory work, incorporated into novel forms of extension over the past half century at Hohenheim University, Stuttgart, Germany. It emphasis a certain understanding of advisory work: as support through “mental help” in structuring and restructuring by informing, motivating and enabling. Through exercises given in the article one can get the idea that problem situations are determined by one's own lack of insight and difficulties in breaking through the limitations of perceptions. The concept presented here in “stages of systematic problem-solving” starts with the perception of a problem by the client. The further critical steps are described within this process from perception of a problem towards solutions and evaluation of results. Two other models that are useful in thinking about problem-solving are also presented. Advisors should value them and be able to make use of them in a flexible way.     

Improvements in school climate associated with enhanced health and welfare services for students

School improvement initiatives are needed to better meet the needs of underprivileged students, to reduce underachievement and to break a continuing cycle of disadvantage. This article describes part of a school improvement initiative in New Zealand that provided additional funding for school nurse and social worker services in nine secondary schools with the most disadvantaged students in New Zealand. It describes the nature and delivery of services provided by the social workers in these schools. In addition, the article reports changes over time in staff and student views about school climate including a comparison with non-participating schools of similar socioeconomic status. The findings indicated that school climate is a useful intermediate measure of the effectiveness of school improvement initiatives. There were significant improvements in staff views about school climate over time, with staff views about school climate becoming more favourable on scales measuring Improvements in the Last 12 Months and Support for Ethnic Diversity compared to eight non-participating schools. Student views were more favourable on scales measuring Satisfaction with School, Support for Achievement and Support for Ethnic Diversity, compared to the non-participating schools.     

Teaching one thing at a time or several things together? – teachers changing their way of handling the object of learning by being engaged in a theory-based professional learning community in mathematics and science

Twelve lower secondary schoolteachers in mathematics and science were asked to teach a topic of their choice during a lesson that was video-recorded. We were able to analyse 10 of the cases and we found that all of them were similar in one respect: concepts and principles were introduced one at a time, each one followed by examples of the concept or principle in question, apparently to highlight its essential meaning. All the teachers participated in three modified lesson studies with three cycles in four different groups during three semesters. The modified lesson studies were built on a theoretical idea supported by a large number of recent studies. The theory states that new meanings (of concepts and principles, for instance) are learned through engaging with instances of contrasting concepts and principles. The core idea is that new meanings derive from differences, not from sameness. After the three modified lesson studies, the teachers were asked to once again teach the same topic as in the recorded lessons before the lesson studies. The new lessons were also recorded and the analysis showed that there was one thing in common in all cases: all of the 10 teachers dealt with the relevant concepts and principles in relation to each other (i.e. simultaneously) and not one at a time. By thus bringing out the differences between them, their meaning was made possible to grasp for the students. The study lends support to the conjecture that the modified lesson study is a powerful tool for enabling teachers to structure the content of their teaching in accordance with a principle that is more powerful in making learning possible, even if this contradicts their taken-for-granted practice.     

Targeting Parenting in Early Childhood: A Public Health Approach to Improve Outcomes for Children Living in Poverty

In this article, the authors posit that programs promoting nurturing parent–child relationships influence outcomes of parents and young children living in poverty through two primary mechanisms: (a) strengthening parents' social support and (b) increasing positive parent–child interactions. The authors discuss evidence for these mechanisms as catalysts for change and provide examples from selected parenting programs that support the influence of nurturing relationships on child and parenting outcomes. The article focuses on prevention programs targeted at children and families living in poverty and closes with a discussion of the potential for widespread implementation and scalability for public health impact.

Will gender equality ever fit in? Contested discursive spaces of university reform

Similar to other European countries, the introduction of non-academic, especially managerial, criteria in higher education has shaped and altered Austrian universities since over a decade. This paper presents the results of a frame analysis of Austrian higher education debates from 1993 until 2010. It outlines how reforms in higher education were prepared and enhanced by a new policy discourse, with a special focus on the way gender equality is framed in reform debates. Our article describes three core frames: ‘from local to global’, ‘from ivory tower to business’ and ‘from civil servant to excellence’. We cluster these three frames around imaginations of space that are embedded in the normative foundations of academia, and discuss how this links up with arguments for gender equality. We furthermore propose to analytically separate two conceptions of the university: the ‘entrepreneurial’ and the ‘managerial’ university.
