Previous attempts to examine the effects of different types of text format on reading have focused on the improvement of reading. The present study investigated the effect of using a text format that might be predicted to disrupt reading. In this study 56 individuals were presented with reading material presented in right-justified format and in'ragged'uneven line format. Subjects performed significantly worse on right-justified material. Subjects who were classified as good readers on the basis of a pretest were more affected than poor readers. It is suggested that this may result from differences in the reading style of good and poor readers.  相似文献

This study examined how communal coping reveals itself in Palestinian refugee camps and the conditions that promote or prevent its occurrence. Individual and dyadic interviews were conducted with 40 mothers and one of their adolescent children living in Palestinian refugee camps in Lebanon. The results revealed that communal coping existed within the mother–adolescent dyad to a certain extent, but was rare within the larger context of the refugee camps. While families and neighbors did not typically verbalize their hardships and actively cope with them as a group, there was often an implicit recognition that they were all experiencing the same uncertainty and stress. Acting upon their uncertainty as a collective, however, was greatly hampered by mistrust within and outside the camps, due to widespread violence, privacy violations, vying for scarce resources, and disloyalty. Parents and adolescents also engaged in protective buffering whereby they attempted to reduce the stress of the family by keeping stress and fears to themselves rather than communicating about them. Even though protective buffering helped the refugees cope with chronic uncertainty and maintain a sense of normalcy, it prevented them from acting upon the problem as a group. Finally, parents emphasized that the child’s education provided hope for the future. Practical implications are discussed.  相似文献

The main aspects of the creation of a monitoring system for the research activities of the members of a higher-education institution are considered. The scientific activities of the lecturers and members of Turgenev Orel State University is used as the basis. It is expected that this system will be an efficient tool for optimal managerial decisions at all levels.  相似文献

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

This paper explores the awareness of the young German and Norwegian participants in the Youth Olympic Games (YOG) of the additional educational mission of this new event, implemented by the International Olympic Committee. Among the questions considered are whether the nature of the event contradicts its claimed intention to focus on both competition and education. Data were collected through a set of interviews with young German and Norwegian athletes at the Singapore YOG in the summer of 2010 and the Innsbruck YOG in the winter of 2012. The findings revealed (1) a focus on elite sport by athletes and their coaches, while the educational aims were considered secondary; (2) that it was problematic for the young participants to focus on education in a high-performance event. The overall conclusion was that the YOG have had only limited success in achieving the educational ambitions of the Olympic Movement.  相似文献
