Characterisation of 15 century red and black pastes used for wall decoration in the Qijmas El-Eshaqi mosque (Cairo, Egypt)     

A.-M. Bakr  T. Kawiak  M. Pawlikowski  Z. Sawlowicz 《Journal of Cultural Heritage》2005,6(4):351-356

The use of coloured pastes for inlaying marble and limestone wall panels is one of the ornamental techniques that were widely used during the Mamluk period in Egypt (1250–1516 AD). Red and black pastes from Qijmas El-Eshaqe mosque (1482 AD) in Cairo were studied to identify their main components. The study of the samples involved the identification of the pigments, additive materials and organic binding media. The study was performed using various analytical methods such as polarising microscopy (PLM), scanning electron microscopy equipped with energy dispersive X-ray analyser (SEM-EDX), inductively-coupled plasma (ICP-AES), X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). These complementary analytical techniques provide precise identification of inorganic and organic substances used in the pastes. The results indicated that the red pigment is mainly obtained from red ochre containing hematite, whereas amorphous carbon (bone black and charcoal) was used to obtain the black colour. Both samples contain calcium sulphate, which was used to give some hardness to the pastes. Beeswax was used as an organic medium in both pastes. The study provides the information required for the conservation of the coloured paste ornaments.  相似文献

Reflections on the Field: Aspirations of Learning Science and the Practical Logic of Instructional Enterprises     

Ernst Z. Rothkopf 《Educational Psychology Review》2008,20(3):351-368

Over 100 years of learning and cognition research have had only modest cumulative impact on teaching, while many other practical domains such as agriculture have shown a steady growth in widely accepted, research-informed practices. Several reasons have been advanced for the painfully slow adoption of science-based instructional procedures. One important but not widely recognized obstacle is proposed here, namely, that the aims of fundamental learning and teaching research do not mesh well with the practical logic of schools. Basic learning research tends to focus on efficiency, i.e., how much can be learned from a given amount of effort or time but teaching efficiency is not a strong concern for schools. This is because they generally focus on global year-end results while the efforts required at the tactical lesson level are only loosely monitored. School administrators tend to reckon costs in terms of the number of engaged teachers and not in the difficulty of each teacher’s job. For these reasons, schools can be expected to have only nominal interests in science-informed, close management of tactical pedagogic units. Psychological work on labor saving possibilities, such as research-based instructive products, is more likely to be readily welcomed than improvements in lesson efficiency, especially in middle and high schools. Instructional enterprises in which the cost and the benefits of instruction are borne by the same agency, such as industrial training, are the most likely consumers of efficiency-related basic cognitive research.

Internal,External, and Government Political Efficacy: Effects on News Use,Discussion, and Political Participation     

Homero Gil de Zúñiga  Trevor Diehl  Alberto Ardévol-Abreu 《广播与电子媒介杂志》2017,61(3):574-596

News use and political discussion are often studied as important factors in understanding the effects of political efficacy on participation. However, measurements of external efficacy often blur distinctions between personal ability and government responsiveness. This study establishes a measure for perceptions of competence in the institutions of democratic government—government efficacy (GE). Drawing on panel survey data from the United States, confirmatory factor analysis introduces GE as a unique construct. Political efficacy dimensions are tested for their impact on news consumption, discussion, and political participation. Results add to the extant literature revolving the role of political efficacy on news use, discussion, and participation.  相似文献   

Verbal retelling abilities in adolescents with and without language-learning disabilities for social studies lectures     

Ward-Lonergan JM  Liles BZ  Anderson AM 《Journal of learning disabilities》1999,32(3):213-223

Verbal retelling abilities for social studies lectures were examined and compared in 20 adolescent boys, ages 12-5 to 14-7, with language-learning disabilities (LLD) and 29 with normal language abilities (NL). Participants viewed one videotaped social studies lecture with a comparison expository discourse structure and one with a causation discourse structure. Following each lecture presentation, participants verbally retold the lecture. Results of several repeated-measures analyses of variance indicated that the group with LLD produced a significantly smaller number of T-units, subordinate clauses, subordinate clauses per T-unit, T-units per second, lecture components per second, and percentage of lecture components in their retellings, compared with the group with NL, regardless of lecture type. Both groups produced a significantly greater number of T-units and subordinate clauses for the comparison lecture. By contrast, both groups recalled a significantly greater number of lecture components per T-unit and per second for the causation lecture. Results indicated that the comparison discourse structure facilitated more substantive and elaborate retellings, whereas the causation discourse structure facilitated more efficient, concise retellings in both groups. Research and instructional implications are discussed.  相似文献   

Latent scrutiny: personal archives as perpetual mementos of the official gaze     

Jacqueline Z. Wilson  Frank Golding 《Archival Science》2016,16(1):93-109

This article examines the significance, in the lives of those who experienced out-of-home care as children, of the archived records of their institutionalisation. The affective ramifications of accessing the records as adults are discussed, with especial focus on the records’ capacity to revive past suffering. Drawing on the work of Bruner (Crit Inq Autumn 1–21,1991, Consumption and everyday life, Sage, London, 1997) and MacIntyre (After virtue: a study in moral theory, University of Notre Dame Press, Notre Dame, 1981), a ‘narrative’ model of the self is utilised to account for the negative effect of systemic flaws in the records’ original composition. Such flaws, it is argued, have the potential to disrupt the individual’s sense of self. Both the authors, who experienced out-of-home care as children, present their own experiences of accessing the records, as case studies. The records’ manifold inaccuracies and inadequacies are interpreted in the light of prevailing welfare practices, in particular a highly damaging judgemental paradigm of gendered and moralistic assumptions of the inferior character of those in care. The authors conclude by arguing that research into the archives should involve the direct participation, as ‘insider researchers’, of those who experienced the matters contained in the records. Such participation is essential if the process of revealing and interpreting the archives is to maintain the dignity of the records’ subject individuals, and ensure the integrity of the research.  相似文献
