The Russian avant-garde painting palette: Documentary and physicochemical codification of organic colorants

In the present article an attempt is made to elucidate the organic colorants commonly encountered in the Russian avant-garde painting palette by a combined art historical, documentary and physicochemical investigation, and to examine the influence of environmental factors on the chromatic profile originally sought by the artist. The overall approach based on written sources is confirmed by measurements on relevant paintings. The documentary research deals with the influences of Orthodox iconography, folkloric art, and occidental modernist tendencies on the Russian avant-garde palette, and studies the effects of contradictory historical processes in the chromatic profile of individual paintings. In the experimental section a series of colorants are investigated concerning the effects of accelerated ageing on experimental painting tables, prepared as watercolor and gouache layers on paper ground. The resulting samples are subjected to colorimetric and spectroscopic measurements, and analogous analytical procedures are applied on samples taken from selected paintings. A systematic comparative study of all data permits evaluation of the materials used in terms of their stability towards extrinsic factors, and proposal of degradation routes in order to assist museum curators and conservators in every concrete case related to the broad spectrum of pigments examined.     

Profile and Motivations of Registered Whole-Body Donors in Turkey: Istanbul University Experience

Little is known regarding the profiles of whole body donors in Muslim majority countries where donation is scarce. Therefore, this study aims to profile registered donors in Turkey by means of a survey. The explored data could be used to improve ongoing campaign efforts and ethical practices such as commemoration services. Registered donors of the donation programs at the two faculties of medicine of Istanbul University were compared with the national population and a cluster analysis was performed to reveal any concealed sub-groups. Data from 188 respondents were analyzed. The majority of registered donors were married (42%), male (65.4%), aged over 50 years (76%), held a tertiary education degree (49.7%), and were irreligious (58.5%). Cluster analysis revealed two groups with significantly different educational levels, marital statuses, and religious choices. Regarding whether their bodies could be used for education or research, the majority (64.5%) of the respondents left the decision to the anatomy department. Similarly, 73.8% approved indefinite use of their organs, body parts and/or skeletons. The respondents were also willing to share their medical history (94.2%) and personal information (81.6%) if needed. Motivational themes for body donation including usefulness, impermanence, religion, awareness, and kinship were devised after a thematic analysis. Among the respondents, 56.5% were registered organ donors and 63.3% were frequent blood donors. The results of this study provide data that may help revising informed consent forms, developing and implementing thanksgiving ceremonies, and selecting additional targets for supporting body donation campaign activities such as organ and blood donation units.     

Device for on-the-water measurement of rowing output

All those who compete in the sport of rowing have used the land rowing machine, Ergometer (commonly called the ‘erg’), manufactured by Concept II (Morrisville, Vermont, USA). Ergon is the Greek word for work, hence the Ergometer measures work. Rowers are commonly ranked according to their ‘erg score.’ The fault in this ranking is that the land Ergometer cannot account for many of the important technical aspects associated with rowing on the water. The goals of this project were to (1) develop a system for on-the-water measurement of work during rowing and then (2) demonstrate the potential of such a system to quantify performance and improve rowing technique. To achieve these goals, force was measured using strain gauges glued to the shaft of the rowing oar and angular displacement was measured using a potentiometer. The force and displacement measurements were sent to a microcontroller, which calculated the total work done in a particular stroke, as well as other parameters, and displayed the values to the rower. The parameters were used to evaluate the performance of three collegiate rowers on the water. The data were also used to plot force profiles, which were reviewed with each rower and the coach to illustrate the rowers’ habits and facilitate improving technique. One rower was ‘tutored’ with the device through five on-the-water practices, after which his force profiles and parameter values demonstrated significant improvement. The device not only provided a standard to which all rowers were compared on the water, but also supplied the rowers with important information on technical aspects of their strokes and pacing themselves.     

Establishing a Competence Profile for the Role of Student-centred Teachers in Higher Education in Belgium

The increasing importance of constructivism in higher education has brought about a shift in pedagogy from a focus on the teacher to a focus on the student. This has important implications for teaching and assessment. A student-centred pedagogy implies a different role for the teacher. What exactly does student-centred teaching require from teachers’ actual teaching practice? What is expected from them in order to teach in a student-centred way? It is in order to respond to these questions that this research project has been carried out establishing a core competence profile of student-centred teachers in higher education. Qualitative data were collected by means of semi-structured in-depth interviews with teachers from different institutions for higher education in Belgium, known for their student-centred way of teaching. This research method is innovative compared to the methods used for existing competence lists in the literature, which were usually developed on the basis of conversations with pedagogical experts. By exploring practice and having teachers participate in the development of a competence list, the acceptance of a competence profile is much higher. The result of the project is a validated competence profile which takes into account the critiques on existing competence lists. The competence profile provides a further insight in the functioning of teachers within a student-centred pedagogy and can be used as a starting point for the educational development of teachers within this pedagogy.     

Identifying a K-10 Developmental Framework for Teaching Philosophy

Abstract

The intention of the study was to identify predictable opportunities for teachers to scaffold middle year students’ philosophical learning. Such opportunities were identified in terms of students’ readiness to learn certain behaviours in the context of a ‘community of inquiry’. Thus it was hoped that the project would provide a useful resource for the teaching of philosophy to middle year students by ascertaining how amenable philosophical learning was to this approach. The study investigated the following questions: (i) what are the indicators of the development under the influence of the COI?; (ii) do these indicators cluster in any particular way? and (iii) is it possible to identify any clustering of indicators that suggests developmental bands?

Graduate LIS Students' Attitude Toward University Libraries and Personnel

This is an attitudinal survey that profiles Kuwait University Library and Information Science (KULIS) students' attitudes concerning Kuwait University's (KU's) libraries. It uses the phenomenological approach to analyze respondents' data regarding confidence in their skills and the effect on attitude toward KU's resources. It furthermore explores the attitudes of KU staff and the level of assistance offered to KULIS students. The results show that most of the respondents visited the library to access electronic resources. Some respondents disagreed that the staff had treated the KULIS suspiciously, yet a majority disagreed that the KU library staff was professionally trained to help KULIS students. Several respondents strongly agreed that they were confident in their searching skills. The results of the survey are used to recommend curriculum changes and ways to improve library and other academic support services at academic institutions generally.
