The instruments for a blind teacher of english: The challenge of the board

This article reports on the training of a blind foreign language teacher of sighted students and the designing of a substitute of the board. A composition of computer devices available today was provided to the blind teacher in order to get pieces of writing projected on a screen. This basic instrument was transformed through instrumental geneses (Rabardel, 1995) i.e., transformations of the blind teacher’s activity and/or of the properties of the artefacts in order to get writings readable for sighted students as well as adapted to didactic purposes. The article deals with knowledge construction, which implies four categories of actions on pieces of writing: adding, erasing, organising and pointing to. The questions involved are: how can a blind teacher manage these various actions? What are the limits of such instrumental geneses?     

Looking back, looking forward: Re-searching the conditions for curriculum integration in the middle years of schooling

In Australia, and internationally, integration is a widely promoted middle school curriculum reform strategy. Integration is claimed to engage students by providing opportunities to work on a few cross-disciplinary objectives, to apply knowledge across the subject boundaries and to work on tasks with meaning and relevance. While these curriculum goals enjoy a certain popularity among middle school reformers and curriculum integration adherents, in practice, the prevalence of integration is patchy and provisional. In this article, we (re) examine two of our studies of middle school integration over the past decade to explore the reasons for this apparent disparity between the rhetoric and the reality. In our re-search for integration, we look back at our data to identify enabling and inhibiting conditions for curriculum reform and develop a list of key program characteristics. Finally, we look forward, drawing on the notion of institutional resilience to speculate on the reasons why some middle school programs seem to flourish while others wither.     

Decontamination of Biocide Treated Museum Objects of the Swiss National Museum’s Collection by Liquid CO2 Technology

ABSTRACT

A decontamination treatment using liquid CO₂ (li-CO₂) and specifically developed for the requirements of museum objects (Lombardo, T., M. Wörle, V. Hubert, E. Hildbrand, I. Mayer, C. Hinterleitner, U. von Arx. 2020. “Influence of Process Parameters on Chlorinated Biocide Decontamination by li-CO₂ on Artificially Contaminated Model Materials.” Studies in Conservation, in press, doi:10.1080/00393630.2019.1641001) was first tested on model materials of wood (with and without coating), silk, and wool with different dyes, paper, and leather in order to evaluate possible material changes. Then, selected museum objects from the collection of the Swiss National Museum were treated to determine the efficiency of biocide decontamination and any resulting chemical and/or structural changes. Results show that dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and chlorpyrifos were successfully removed. Wool, silk, leather, and non-coated wood did not experience any detectable modifications, while moderate to major modifications were observed in wood coated with shellac and polychromy.

A midwifery model of care for childbearing women at high risk: genuine caring in caring for the genuine

According to this paper's synthesis of research, three constituents of ideal midwifery care emerge. First, a dignity-protective action takes place in a midwife's caring relationship with a childbearing woman at high risk and includes mutuality, trust, ongoing dialogue, enduring presence, and shared responsibility. Secondly, the midwife's embodied knowledge is based on genuineness to oneself and consists of theoretical, practical, intuitive, and reflective knowledge. Finally, nurse-midwives have a special responsibility to balance the natural and medical perspectives in the care of childbearing women at high risk, especially by promoting the woman's inborn capacity to be a mother and to give birth in a natural manner. This midwifery model of care is labeled "Genuine Caring in Caring for the Genuine." Here, the word genuine expresses the nature of midwifery care, as well as the nature of each pregnant woman being cared for as a unique individual.
