Helping lecturers address and formulate teaching challenges: an exploratory study
2018
International audience; In this paper we present an exploratory study on the kind of questions or difficulties lecturers point out at the beginning of an educational course – to be addressed in it. These questions happen to be very general and are poorly connected to the knowledge to be taught. We suggest a twofold interpretation of this phenomenon. On the one hand, and in the line of the didactic transposition theory, teachers do not allow themselves to raise questions about the knowledge that is supposed to be their main field of expertise. On the other hand, the prevailing institutional pedagogy does not provide teachers with a fruitful enough conceptual frame to formulate this kind of q…
Results of a dental care protocol for mentally handicapped patients set in a primary health care area in Spain
2007
Objective: Disabled people have the same right as other people to receive the health care they need, but they sometimes have difficulties to achieve it. In Castilla y Leon it has come into effect a law to guarantee Primary and Secondary Care coordination to provide dental treatment under sedation or anaesthesia to mentally disabled people who need it. Our aim is to evaluate the results of the implementation of such a law through a specific protocol in our health setting. Study design: Descriptive, made in a Health Area over a year, on mentally disabled people who were sent to hospital for treatment under anaesthesia after Primary Dental Care Units assessment. It has been studied the age, ge…
De la performance musicale dans la Guyane traditionnelle : expression cognitive singulière d?une musique-verbe
2021
Guianese culture and traditional music, here evoked, are various. It is more a transcultural process that, along centuries, gave an original result born in the Americas, in Guiana in this case. It is a form of refoundation, of recreation of cultures and new human beings generally called Creoles. The musical performance, that I study here, is the echo of social and cultural space of this reformulation of thought, life, and conception of the world. It is, as well, a mean of transposition and transformation of the values issued of diverse sources and categories. It is in no way a second-rate cultural practice, as it is the place where were born philosophies and actions for common life as well …
Clinico-Biomechanical Issues and Dynamic Stabilization When Considering Stem Cell Treatment for Degenerative Disc Disease
2013
After reading the article published in Transplantation (1), scientists are to be congratulatedVespecially with the clinical results as published. Looking for alternatives to avoid fusion is part of function-preserving spine care, as it should be the last option to be undertaken while keeping the debate open (2, 3). Nevertheless, we would like to point out some questions that arise from a clinical point of view from our daily surgical practice. First, several clinical presentations and procedures are compared without taking into account that they are different treatments applied for different disc disease situations (discectomy is performed for disc herniation with radicular symptoms, disc p…
Modifying the texture of foods for infants and young children
2015
The first section of this chapter describes the evolutions in oral physiology (anatomical motor components, oral motor skills and feeding skills) in healthy children (< 3 years). The second section describes how each type of texture is accepted at each oral physiology stage, and how exposures to textures impact oral physiology development and acceptability of textures. The third section shows how the need to modify food texture for infant foods is addressed, through national regulations or recommendations from public health bodies, and describes practices of texture modification, based on national surveys and case reports (including baby-led weaning). The chapter is closed by a commentary o…
Tenfold increase in efficiency from a reference blue OLED
2018
Abstract Starting from a reference single-layer light-emitting diode based on the blue phosphorescent bis-cyclometallated iridium complex FIrpic as guest, hosted in a PVK (non-conjugated poly(vynilcarbazole)) matrix, different strategies are followed to improve the efficiency of the devices through the combination of solution processed and evaporated layers. Injection of charges from the electrodes has been varied by using different conductive PEDOT: PSS as hole injection layer and a nanoscale Cs2CO3 interlayer as electron injection and hole-blocking film. Furthermore, a separated electron injection/hole blocking evaporated layer, TPBi or 3TPYMB, is introduced in double-layer devices to enh…
Designing Medical Devices Based on Silicon Polymeric Material with Controlled Release of Local Anesthetics
2012
The drug delivery systems that are the object of this article take the form of a polymer matrix made of silicone containing a drug. These devices can be used as patches for local dermal applications releasing the drug in a controlled manner. The model active agent, lidocaine hydrochloride was chosen from the range of local anesthetics. When the drug is restricted to the surface, it is released more rapidly than when it is allowed to spread evenly throughout the silicon structure. When hydrophilic polymers such as PVA and HEC are mixed in with the lidocaine hydrochloride and deposited on the surface of the polymer matrix, we observed that the burst effect was eliminated without modifying the…
Introduction to the Book and the Comparative Study
2016
Chapter 1 of Re-Becoming Universities contextualizes and describes the contents of the book based on the study: Change in Networks, Higher Education and Knowledge Societies (CINHEKS). The CINHEKS study was a six country international comparative study focused on the way in which contemporary higher education institutions and networked within and between networked knowledge societies. The countries in focus are Finland, Germany, Portugal, The Russian Federation, The United Kingdom and the United States of America.
Creating Individual Journal Rankings Based on a Community Approach
2010
Selecting appropriate publication outlets is crucial to any researcher. Journal rankings can be used to guide the selection, but their usefulness may be limited for particular audiences. In this paper, it is argued that especially young researchers and researchers in interdisciplinary fields can benefit from targeting research efforts to a specific community. This can be facilitated by an individually built journal ranking that exploits a community building perspective and by a more transparent process of use. The approach introduced here is based on an analysis of both traditional journal rankings and behavior of academic communities. As a result, we present a procedure for building and us…
Vertical Integration due to Software Systems' Modularity
2009
In their product portfolio, OSS/BSS software vendors make products pre-integrated with each other as well as with other related OSS/BSS products. Prior to the full-scale development and integration, it is vital for these vendors to assess which products are reasonable to integrate. Such integration of software may be aimed at achieving different goals, such as: Reducing software integration efforts. Software vendors aim at maximizing their profits, whereas their customers (i.e., CSPs) aim at minimizing their costs by avoiding the integration job. As a result, to approach a win–win scenario, vendors provide already integrated products or subsystems (pre-integrated modules). Sharing similar k…
