Consolidation of Black-dyed Māori Textile Artefacts: Evaluating the Efficacy of Sodium Alginate

Black-dyed artefacts are found in museums worldwide, many produced using an iron-tannate compound. Deterioration of iron-tannate dyed artefacts is an international preservation issue: in New Zealand the deterioration of paru (iron-tannate) dyed Māori textiles is widespread. This article reports experimental work testing the efficacy of sodium alginate, a consolidant developed for deteriorated paru-dyed muka (fibre from harakeke; Phormium tenax). The colour stability, strength retention, and acidity of paru-dyed muka consolidated with sodium alginate (0.25, 0.5, and 1% w/v in water) was tested pre- and post-artificial light ageing. This study found that sodium alginate had no negative effect on paru-dyed muka and in some cases provided benefit. Interestingly, the colour of paru-dyed muka is substantially more stable in UV-filtered light than previously recognised. Also microfading results were in agreement with visual assessments of colour change at 1 Mlux hour exposure, providing confidence in this relatively new technique to assess colour change.

Researching female professors: the difficulties of representation,positionality and power in feminist research

This article draws on findings from my doctoral research to exemplify some of the difficulties I encountered when interviewing 20 female professors¹1. In the UK context, the title of ‘professor’ is reserved for full professors only – that is, those with either an established or personal chair. and subsequently writing about their life histories. In this article, I discuss how I addressed the issues of representing and positioning my participants, and I reflect on the power dynamics present in the research process. The article contends that by drawing on Bourdieu and Wacquant's [An Invitation to Reflexive Sociology. Chicago, IL: University of Chicago Press] understanding of reflexivity and feminist interpretations of their work including McNay [“Gender, Habitus and the Field: Pierre Bourdieu and the Limits of Reflexivity.” Theory Culture Society 16: 95] and Adkins [“Reflexivity Freedom or Habit of Gender?” Theory Culture Society 20: 21], valuable research can be produced, despite the difficulties. A related aim of this paper is to reflect back after four years in an academic post on my position as a novice researcher, and some of the associated issues facing doctoral students, particularly the problems with researching upwards [Walford, G. 2011 Walford, G. 2011. “Researching the Powerful.” British Educational Research Association on-line resource.

The C.R.E.A.T.E. approach to primary literature shifts undergraduates' self-assessed ability to read and analyze journal articles, attitudes about science, and epistemological beliefs

The C.R.E.A.T.E. (Consider, Read, Elucidate hypotheses, Analyze and interpret data, Think of the next Experiment) method uses intensive analysis of primary literature in the undergraduate classroom to demystify and humanize science. We have reported previously that the method improves students' critical thinking and content integration abilities, while at the same time enhancing their self-reported understanding of "who does science, and why." We report here the results of an assessment that addressed C.R.E.A.T.E. students' attitudes about the nature of science, beliefs about learning, and confidence in their ability to read, analyze, and explain research articles. Using a Likert-style survey administered pre- and postcourse, we found significant changes in students' confidence in their ability to read and analyze primary literature, self-assessed understanding of the nature of science, and epistemological beliefs (e.g., their sense of whether knowledge is certain and scientific talent innate). Thus, within a single semester, the inexpensive C.R.E.A.T.E. method can shift not just students' analytical abilities and understanding of scientists as people, but can also positively affect students' confidence with analysis of primary literature, their insight into the processes of science, and their beliefs about learning.

Degree Performance as a Function of Age,Gender, Prior Qualifications and Discipline Studied

The computerised records of a large university were analysed in an attempt to determine which variables served as predictors of degree performance. Age was a powerful predictor: mature students gained better degrees on average than younger students; and mature students with non‐traditional qualifications obtained the best degrees of all. Gender, year of graduation, and type of qualification were weak predictors of performance, but degree classifications were found to differ significantly across disciplines. The results are broadly consistent with previous studies, and suggest that opening access to mature students and to those with non‐traditional qualifications has not led to any diminution of standards. However, variations between disciplines and, in national statistics, between different years, suggest that steps may need to be taken to standardise degree classifications.     

体育教育考生考前营养知识、态度、行为的调查分析

以辽宁师范大学体育学院2009级体育教育专业学生为研究对象,对其在高考体育加试之前的营养知识、态度、行为进行一次问卷调查,并对调查结果进行分析。结果显示：体育教育考生在考前营养知识的掌握程度仅限于常识,认为考前营养补充对运动成绩有着非常重要的作用,体育教育考生考前的饮食行为比较合理,几乎没有体育教育考生使用营养补品。
