Granite desalination using electromigration. Influence of type of granite and saline contaminant

We describe the results of electromigration desalination of two soluble salt-contaminated Galician granites. The efficacy of electromigration, which had not been previously applied to granite, was assessed for two types of granite contaminated with a 20% NaCl solution and seawater. Desalination effectiveness was evaluated as follows: (1) analysis of anode and cathode ion content during testing; (2) analysis of ions at different distances from the electrodes after testing; (3) pH assessment of the stone surfaces; and (4) evaluation of colour changes. Results were very satisfactory; by the end of testing, chloride was reduced by almost 100% in both the NaCl and seawater contaminated samples. Sulfate reduction was also significant, despite this ion's lower mobility. The granite pH values remained close to neutral and colour changes were minimal. The difference in effectiveness of the process for the two types of stone was associated with their dissimilar pore structure.     

Performance strategies of US Olympians in practice and competition

Until recently, no self‐report instruments have examined psychological skills use in both practice and competition. In light of the significant role of practice in sport performance outcomes, a need exists to measure these skills in both domains. This study was designed to investigate differences in performance strategies of US Olympians in both practice and competition. The Test of Performance Strategies was administered to 176 US participants in the 2000 Sydney Olympic Summer Games. Discriminant function analyses demonstrated significant differences between medalists and nonmedalists in both the competition and practice performance strategies. Furthermore, significant gender and age differences were identified for competition strategies only. The 16 subscales of the TOPS, with two exceptions, create an internally stable instrument with moderate predictive ability relative to quality of sport performance, gender, and age in this elite sample of athletes.     

Determinants of Research Productivity in Spanish Academia

This article aims to widen the empirical evidence about the determinants of Spanish academics’ publication productivity across fields of study. We use the Spanish Survey on Human Resources in Science and Technology addressed to Spanish resident PhDs employed in Spanish universities as academics. Productivity is measured as the total number of publications in a three‐year period. We show how personal and academic variables explain differences in productivity within universities and fields of studies and across fields of research. Female workers report lower productivity than their male counterparts, but family responsibilities do not explain this gender gap. The type of contract and tenure or rank do not seem to have any influence on productivity. Researchers seeking professional promotion rather than altruism or personal satisfaction are more productive and young scholars publish more than their older counterparts. Additionally, we find a certain research‐teaching trade‐off and some nuances in the predictors of publication productivity across birth cohorts and fields of study. Finally, international cooperation is one of the most relevant determinants of the number of publications, regardless of the birth cohort. The institutional context in the Spanish research system as regards requirements for promotion and the assessment of research outcomes may contribute to the understanding and interpretation of our results.

Feedback in Distance Learning Programmes in Languages: Attitudes to linguistic faults and implications for the learning process

In distance learning provision in languages, fault correction and feedback can facilitate teacher–student dialogue. This article examines teachers’ beliefs and assumptions about faults and the attitudes of both teachers and learners towards the correction process, all of which can play a key role in fostering this dialogue. Our findings are based on two surveys, one of 215 students enrolled on an intermediate Open University Spanish course and one of a sample of 18 tutors who teach on this course. The results of the two questionnaires suggest that the strategies currently in use for identifying and correcting faults may not be explicit enough. We conclude that this problem may be addressed if both tutors and students are given the tools to make the process more transparent and are encouraged to see dialogue as an essential component in the feedback mechanism.     

Inequalities in Entry to Higher Education: a Comparison Over Time between Scotland and England and Wales

This paper uses data from the Scottish School Leavers Surveys and the England and Wales Youth Cohort Study to analyse changes over time in gender and social class inequalities in the opportunities of young people to participate in higher education (HE) in Scotland, England and Wales. The results show that in Great Britain, in the period from the end of the 1980s to 2001–2002, HE expansion has benefited more women than men, and in the most recent time points has led to a reduction in social inequalities. However, gender and social class differences persist at degree level and in the choice of subject studied. The results also show that higher proportions of working class students enter HE in Scotland than in England and Wales, but that social inequalities are more marked in Scotland. The larger availability of vocational routes in Scotland, at both sub‐degree and degree level, may explain country differences in HE participation rate of working class students.     

Cross-lagged cross-subject bidirectional predictions among achievements in mathematics,English language and Chinese language of school children

This study aimed to explore the cross-lagged association of achievements in mathematics and languages. While the effect of language on achievements in mathematics is well-documented, few studies have examined the reciprocal relationships among mathematics, the Chinese language and the English language in the same study. This study conducted a secondary analysis of longitudinal achievement data collected through the Territory-wide System Assessment (TSA) in Hong Kong. The sample comprised 48,547 third-grade, unbalanced bilingual students who were measured three times over six years: in 2007 (in Grade 3), 2010 (Grade 6) and 2013 (Grade 9). Multilevel cross-lagged analysis found prior achievement in a subject was the strongest predictor of achievement in that subject three years later. Furthermore, cross-subject bidirectional prediction was found among achievements in mathematics, Chinese language and English language for students from Grade 3 to Grade 6 and from Grade 6 to Grade 9.     

Reforming education in post-partition Northern Ireland: state control and churches’ interference

ABSTRACT

After the partition of Ireland, the newly established parliament in Belfast was given control over education. The unionist government, mainly representing the majoritarian Protestant population, embarked on a reform of the pre-existing denominational education system and tried to persuade all the churches to transfer their schools to state control in exchange for public funding. Despite the sincere efforts of the first Minister of Education, the Catholic Church rejected interference in education from a government that its followers perceived as hostile, while the Protestant churches became increasingly intransigent in their demands for more control over state schools. In order to ensure their support, the government met their requests, ignoring the instances of teachers and principals who called for independence from clerical managers. The result was a segregated education system that contributed to maintain the deep divisions of the Northern Irish society.
