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.     

Supportive communication from bystanders of cyberbullying: indirect effects and interactions between source and message characteristics

Cyberbullying is an increasingly common experience that produces psychosocial consequences for targets. Interventions encouraging bystanders to support targets of cyberbullying are limited by a lack of focus on what to communicate. This study considers supportive messages that emphasize emotional comfort, attributions of responsibility, and beliefs that people can change as relevant to this context, and it examines how perceptions of messages differ based on whether support providers have or lack experience with cyberbullying. We extend research on the indirect effects model of supportive communication by randomly assigning participants (N?=?304), who self-identify as targets of cyberbullying, to message and source conditions and assessing their perceptions of messages, providers, and outcomes. Impressions of messages mediate their influence on outcomes, and the experiential similarity of support providers moderates these effects. Certain messages, notably those contending that bullies can change, are less effective when delivered by sources who lack experience with bullying.     

How we done it good: Research through design as a legitimate methodology for librarianship

“How we done it good” publications—a genre concerning project-based approaches that describe how (and sometimes why) something was done—are often rebuked in the library research community for lacking traditional scientific validity, reliability, and generalizability. While scientific methodologies may be a common approach to research and inquiry, they are not the only methodological paradigms. This research posits that the how we done it good paradigm in librarianship reflects a valid and legitimate approach to research. By drawing on the concept of research through design, this study shows how these how we done it good projects reflect design methodologies which draw rigor from process, invention, relevance, and extensibility rather than replicability, generalizability, and predictability. Although these projects implicitly reflect research through design, the methodology is not yet explicitly harnessed in librarianship. More support for these types of projects can be achieved by making the legitimate design framework more explicit and increasing support from publication venues.     

Investigating married adults’ communal coping with genetic health risk and perceived discrimination

Increased genetic testing in personalized medicine presents unique challenges for couples, including managing disease risk and potential discrimination as a couple. This study investigated couples’ conflicts and support gaps as they coped with perceived genetic discrimination. We also explored the degree to which communal coping was beneficial in reducing support gaps and ultimately stress. Dyadic analysis of married adults (N?=?266, 133 couples), in which one person had the genetic risk for serious illness, showed that perceived discrimination predicted more frequent conflicts about alpha-1 antitrypsin deficiency-related treatment, privacy boundaries, and finances, which, in turn, predicted wider gaps in emotion and esteem support, and greater stress for both spouses. Communal coping predicted lower support gaps for both partners and marginally lower stress.     

Pragmatismus und seine Rezeption in der deutschen Sportpädagogik

A discourse analysis of sports pedagogy regarding the pragmatic turn shows clearly that sports pedagogy has taken up ideas from other disciplines only in a coincidental or haphazard way. Genuine new forms of action or reflection were not recognized or did not show themselves in the discipline outside of common pedagogical discourses. Such resistance concerning concepts from other disciplines shows itself especially clearly in the turns following the pragmatic turn. Only where the “narrative turn” is concerned do we see traces of this discourse in sports pedagogy as well. However, these traces have already faded in the last 10 years. There are two reasons that sports pedagogy does not engage in discourse with other disciplines. Firstly, the obvious value of sport and physical exercise can make it seem unnecessary for sports pedagogy to meddle in the arguments of pedagogic worth experienced in other subjects. Secondly, the discipline still appears to be caught up in the mythology and terminology of German idealism.     

Warum scheiterte 1920 August Biers Antrag auf einen „Doktor der Leibesübungen“?

This article deals with the first years of foundation of the private Deutsche Hochschule für Leibesübungen (DHfL). It focuses on the question of why August Bier’s application for a Doktor der Leibesübungen in 1920 was refused. In the same year the DHfL also made an application for the education in state-run schools which was already task of the state-run Preußische Landesturnanstalt at Spandau. As the DHfL combined this application with its insistence on its autonomous status an application for a Doktor der Leibesübungen had implied financial, conceptual and institutional obligations for Prussia and at the same time a renuncitation of its sovereign rights. This thesis was proved by a comparison between the doctorate in physical education and the doctorate for businessmen at Cologne University.
