Predicting the Grades of Low-Income–Ethnic-Minority Students From Teacher-Student Discrepancies in Reported Motivation

The aims of this study were to investigate the effects of discrepancies between teachers' perceptions of students' motivation and students' reports of their motivation on math and English grades and to identify possible gender and ethnic differences. Participants included 215 low-income, ethnic-minority students and their teachers in academically struggling schools. Discrepancy in motivation ratings accounted for a significant amount of variation in final grades. This teacher-student discrepancy effect was larger than both the effect of students' recent standardized test scores and the effect of self-efficacy in both subjects. Girls were found to attract positive teacher bias, but their grades were not differentially affected. Differences in teacher-student discrepancy effects between African American and Latino students were not found.     

Encoding Effects on First-Graders' Use of Manipulatives

The effects of prior encodings of manipulatives (red and blue plastic chips) on children's ability to use them as representations of quantity were tested. First graders (N = 73) were assigned to four conditions in which the encoding of plastic chips was experimentally manipulated. All children then participated in an addition activity that relied on the chips' quantitative representations. Children who were given quantitative encodings were better able to use the chips with meaning relative to those who played with them during the encoding phase. Children who perceived the chips as toys after encoding were similarly hindered on their ability to use them as quantities. The findings suggest that prior encodings are predictive of children's quantitative representations of manipulatives.     

Should Homosexuality be Taught as an Acceptable Alternative Lifestyle? A Muslim perspective

In most western countries homosexuality is gaining growing support as an alternative lifestyle and, being a part of sex education in schools, is presented to children as a positive image. The first section of the paper summarises the current political and social aspirations of the gay and lesbian movement and examines the underlying values and assumptions in this position as well as its educational implications. The second section considers evidence of the extent to which the gay and lesbian aspirations are receiving a sympathetic hearing from liberals, sex education specialists, Christians, members of other world religions and the population at large. The third section develops a Muslim perspective on (male) homosexuality, based mainly on Islamic teaching but also referring where appropriate to practices in Muslim countries. Muslims oppose the teaching of homosexuality not only because Islam proclaims homosexual practices to be an ‘abomination’, but also because the notion of homosexuality as a lifestyle at all, let alone a natural and equally valid one, is itself incoherent from a Muslim perspective. The paper concludes with some suggestions about the educational implications of the Muslim perspective.     

Constructing football through magic: an ethnographic study of football supporters

This article presents an analysis of football supporters as magicians based on the theory of magic developed by Marcel Mauss. The research was conducted in co-operation with a local football club from Sweden called Malmö FF. Taking into consideration how the supporters see their position in the club and their contribution, it is possible to explain their behaviour and involvement in terms of a collective phenomenon that requires a clearly stated objective and is achieved through technical elements. The extensive usage of props, language and symbols is supposed to influence the reality according to the wishes of the user. This article follows previous research of modern phenomena in terms of magic as presented by Thomas O’Dell (O’Dell, Spas and the Cultural Economy) and Peter Pels (Pels, Magic and Modernity, 183–99). Such approach can explain how the engagement and the unique relationship are still possible in a highly commercialized and commoditized world of modern football.     

“To Reach the Lands of Freedom”: Petitions of Polish Displaced Persons to American Poles,Moral Screening and the Role of Diaspora in Refugee Resettlement

ABSTRACT

In 1949, in the wake of the USA’s Displaced Persons Act of 1948, the American Committee for the Resettlement of Polish Displaced Persons received thousands of letters from refugees of peasant and worker background residing in camps in Germany and Austria. These potential immigrants appealed to the Polish diaspora for help with securing assurances of accommodation and work which would enable them to resettle in the USA. This paper investigates the discursive strategies of the authors and the wider meanings of their emigration endeavour. Firstly, it demonstrates that non-elite Displaced Persons (DPs) adopted the language of martyrology, patriotism, anti-Communism and freedom to maximise their chances of emigration. These DPs did not evoke the language of rights as they appealed to the traditional network of support, based on benevolence and familiarity. Secondly, it argues that the American Poles and Polish social elites played a crucial role in resettlement of the DPs, providing an additional layer of screening, here called ‘the moral screening’. It is an example of how ethnic and cultural communities mediated the resettlement procedures supervised by international humanitarian organisations. Using a ‘history from below’ approach, this article argues that during this episode of migration, political and economic ideological underpinnings intertwined.     

Surface changes upon high-frequency plasma treatment of heritage photographs

Recent research, concerning the application of high-frequency cold plasma in restoration and preservation of the cultural heritage, has included the objects derived from organic materials, which are highly sensitive to microclimate factors. Historical photographs made on paper base and covered with various emulsions belong to this category of heritage objects, and make the purpose of the present study. Plasma treatment was used to enhance the aesthetic aspect of the photographs by a cleaning treatment involving either physical and/or chemical etching, which did not cause major physicochemical changes on the plasma-treated surface. The photographs before and after plasma treatments were analysed by optical and atomic force microscopy, scanning electron microscopy with energy-dispersive X-ray microanalysis, Fourier transform infrared spectroscopy, colour, gloss and contact angle measurements.     

On the use of ASTM closed vessel tests in accelerated ageing research

The ASTM D6819-02e3 standard for testing the accelerated ageing of paper, published in 2002, recommends using closed glass vials in order to keep the degradation products in contact with the paper and thus permitting a better simulation of the natural ageing conditions inside closed books. In the present study, the actual conditions and their stability inside closed vessels have been evaluated. The necessity of assuring a very high sealing performance (tightness) of the systems in order to avoid leakage of water vapour is the main drawback of this ageing method. Systematic studies presented in this publication tried to monitor this tightness and have provided data that helped to answer the question of what circumstances could lead to achieving its improvement. Both gravimetric monitoring of water content in vials and “in situ” IR measurements of the aged paper humidity have been applied for this purpose. As a result, better sealing materials (gaskets and caps) than those recommended by the ASTM standard, have been found. Additionally, application of a dynamometric spanner for closing the vials is recommended, as this is a guarantee of reasonably high and recurring tightness of the systems used in tests. Nevertheless, the systematic, linear with time, loss of moisture for all used vials was observed. A 9% loss of the initial moisture content in samples of the aged paper was observed for the tested conditions (14 days at 90 °C). Therefore, it seems that including some kind of gravimetric control for ageing tests performed in closed vessels is of essential importance.Kinetic studies of accelerated ageing in both closed and open systems, as monitored by DP and breaking length measurements, unexpectedly show that no statistically meaningful difference of degradation rates can be observed. On the other hand, the pH and whiteness index values reveal a meaningful difference between the rates of ageing in these systems, thus confirming the basic assumption of the ASTM test concerning the interaction of paper degradation products with the paper itself.     

Exploring the Structure of Teachers’ Emotional Labor in the Classroom: A Multitrait–Multimethod Analysis

This study tests whether teachers’ emotional labor in classroom settings is optimally conceptualized according to the type of emotional labor strategy involved (genuinely expressing, hiding, and faking emotions), the specific type of emotion being performed in class (e.g., enjoyment vs. pride vs. anxiety), or both strategy type and emotion type. Multitrait–multimethod analyses of 1,086 Canadian teachers’ survey responses showed teachers’ responses to emotional labor items to be most reliably differentiated according to both specific types of emotional labor strategies as well as the valence of the emotion being performed. Findings were largely consistent with common “display rules” encouraging expression of positive emotions and hiding of negative emotions by teachers in classroom settings. Results further showed teachers’ emotional labor strategies for negative emotions to be particularly contingent on the specific discrete emotion involved, highlighting the complexity of expressing negative emotions as a behavior management strategy.     

Is there an association of allergy and cardiovascular disease?

Cardiovascular diseases and allergic diseases occur commonly in developed countries. They lead to serious health complications and significantly impair the quality of life. Both types of diseases are characterized by excessive inflammatory processes. Recent studies suggest a link between allergy and an increased risk of cardiovascular disease, resulting from overactivity of the immune system in allergic diseases and increased synthesis of proinflammatory mediators, which has been well documented in the pathogenesis of atherosclerosis. The aim of this article is to present current data on the role of proinflammatory factors in the pathogenesis of cardiovascular diseases and allergies and on potential relationship between these disorders.     

Learning biology and mathematics outdoors: effects and attitudes in a Swedish high school context

This research suggests that learning biology in an outdoor environment has a positive cognitive and affective impact on 13–15-year-old, Swedish high school pupils. Eighty-five pupils in four classes participated in a quasi-experimental design. Half the pupils, taking a biology course in ecology or diversity of life, had several lessons outdoors and the other half were taught indoors. All of the classes, but one, also had mathematics lessons outdoors once a week. Twenty-one pupils were interviewed five months after the course and all were positive towards the new learning environment they had experienced outdoors in biology and/or mathematics. They also valued the higher degree of interaction among the pupils. Other findings from the interviews were that the pupils from the outdoor classes showed a higher degree of long-term knowledge retention. They remembered both activities and contents better than the pupils in the indoor classes. An essay-type question assessing their biological understanding qualitatively according to the Structure of Observed Learning Outcome taxonomy revealed no differences between the groups. The results are discussed in the light of neurocognitive models of long-term memory.
