Towards a Praxeology of Teaching

Both preservice and seasoned teachers experience a considerable gap between theory and prescriptions for teaching and their day-to-day practice. We concep- tualize this gap in terms of the difference between descriptions of practice and practice itself. Descriptions cannot include the tacit understanding against which specific acts of teaching become meaningful; thus, they are inherently out of syn- chrony with practice. We illustrate how Bourdieu’s notion of habitus (a set of dispositions) accounts for appropriate actions in situations where there is no “time out” for deliberation and how coteaching can support preservice teachers’ development of this habitus. Les étudiants-maîtres comme les enseignants chevronnés ressentent l’écart considérable entre la théorie et les règles de l’enseignement et leur pratique quotidienne. Les auteurs conceptualisent cet écart en termes de différence entre les descriptions de la pratique et la pratique elle-même. Les descriptions ne peuvent inclure la compréhension tacite par rapport à laquelle des activités pré- cises d’enseignement prennent un sens; aussi ces descriptions en elles-mêmes ne concordent pas avec la pratique. Les auteurs illustrent comment la notion d’habitus de Bourdieu (un ensemble de dispositions) explique la pertinence des actions effectuées dans des situations où il n’y a pas de temps pour délibérer et comment le coenseignement peut favoriser de développement de cet habitus chez les stagiaires.

Biostability of an orthopaedic device and its long-term implantable biomaterials

The BDyn device is a bilateral posterior dynamic stabilisation spinal implant used to treat degenerative disc disease. The BDyn device consists of a polycarbonate urethane (PCU) component, a silicone component, a mobile titanium alloy rod, a fixed titanium alloy rod and it is fixed to the vertebrae by titanium alloy pedicle screws. The viscoelastic properties, chemical structure and surface morphological changes of the untreated, in vitro degraded and in vivo degraded were compared. The macro and micro-scale viscoelastic properties, chemical structure and surface morphology of five long-term implantable PCU biomaterials, which were in vitro degraded by four separate degradation methods were also investigated. No resonant frequencies were reported for the untreated and in vitro degraded components and devices however, resonance was detected in the frequency sweep test of BDyn Explant 2 with the sharp increase of the loss stiffness occurred at 4 Hz; this highlights the importance of evaluating orthopaedic devices with frequency dependent mechanical testing techniques. The biomaterials were viscoelastic throughout the frequency range tested and were significantly different at specific frequencies when comparing untreated specimens to specimens degraded by a specific degradation method; this further highlights the need to evaluate elastomeric biomaterials with frequency dependent mechanical testing techniques

The Creative Commons Public Domain Dedication waiver (http://creativecommons.org/publicdomain/zero/1.0/) applies to the data made available in this article, unless otherwise statedBackground: This paper describes the development of a model of Comprehensive Primary Health Care (CPHC) applicable to the Australian context. CPHC holds promise as an effective model of health system organization able to improve population health and increase health equity. However, there is little literature that describes and evaluates CPHC as a whole, with most evaluation focusing on specific programs. The lack of a consensus on what constitutes CPHC, and the complex and context-sensitive nature of CPHC are all barriers to evaluation. Methods: The research was undertaken in partnership with six Australian primary health care services: four state government funded and managed services, one sexual health non-government organization, and one Aboriginal community controlled health service. A draft model was crafted combining program logic and theory-based approaches, drawing on relevant literature, 68 interview s with primary health care se rvice staff, and researcher experience. The model was then refined through an iterative process involving two to three workshops at each of the six participating primary health care services, engaging health service staff, regional health executives and central health department staff. Results: The resultant Southgate Model of CPHC in Australia model articulates the theory of change of how and why CPHC service components and activities, based on t he theory, evidence and values which underpin a CPHC approach, are likely to lead to indivi dual and population health outcome s and increased health equity. The model captures the importance of context, the mechanisms of CPHC, and the space for action services have to work within. The process of development engendered and supported collaborati ve relationships between researchers and stakeholders and the product provide d a description of CPHC as a whole and a framework for evaluation. The model was endorsed at a research symposium involving inv estigators, service staff, and key stakeholders. Conclusions: The development of a theory-based program logi c model provided a framework for evaluation that allows the tracking of progress towards desired outcomes and exploration of the particular aspects of context and mechanisms that produce outcomes. This is important because there are no existing models which enable the evaluation of CPHC services in their entirety

Research support of the WETNET Program

This study examines various aspects of the Microwave Vegetation Index (MVI). MVI is a derived signal created by differencing the spectral response of the 37 GHz horizontally and vertically polarized passive microwave signals. The microwave signal employed to derive this index is thought to be primarily influenced by vegetation structure, vegetation growth, standing water, and precipitation. The state of California is the study site for this research. Imagery from the Special Sensor Microwave/Imager (SSM/I) is used for the creation of MVI datasets analyzed in this research. The object of this research is to determine whether MVI corresponds with some quantifiable vegetation parameter (such as vegetation density) or whether the index is more affected by known biogeophysical parameters such antecedent precipitation. A secondary question associated with the above is whether the vegetation attributes that MVI is employed to determine can be more easily and accurately evaluated by other remote sensing means. An important associated question to be addressed in the study is the effect of different multi-temporal composting techniques on the derived MVI dataset. This work advances our understanding of the fundamental nature of MVI by studying vegetation as a mixture of structural types, such as forest and grassland. The study further advances our understanding by creating multitemporal precipitation datasets to compare the affects of precipitation upon MVI. This work will help to lay the groundwork for the use of passive microwave spectral information either as an adjunct to visible and near infrared imagery in areas where that is feasible or for the use of passive microwave alone in areas of moderate cloud coverage. In this research, an MVI dataset, spanning the period February 15, 1989 through April 25, 1990, has been created using National Aeronautic and Space Administration (NASA) supplied brightness temperature data. Information from the DMSP satellite 37 GHz wavelength SSM/I sensor in both horizontal and vertical polarization has been processed using the MVI algorithm. In conjunction with the MVI algorithm a multitemporal compositing technique was used to create datasets that correspond to 14 day periods. In this technical report, Section Two contains background information on the State of California and the three MVI study sites. Section Three describes the methods used to create the MVI and independent variables datasets. Section Four presents the results of the experiment. Section Five summarizes and concludes the work

A Decade of Friction Stir Welding R and D at NASA's Marshall Space Flight Center and a Glance into the Future

Welding at NASA's Marshall Space Flight Center (MSFC), Huntsville, Alabama, has taken a new direction through the last 10 years. Fusion welding processes, namely variable polarity plasma arc (VPPA) and tungsten inert gas (TIG) were once the corner stone of welding development in the Space Flight Center's welding laboratories, located in the part of MSFC know as National Center for Advanced Manufacturing (NCM). Developed specifically to support the Shuttle Program's External Tank and later International Space Station manufacturing programs, was viewed as the paragon of welding processes for joining aluminum alloys. Much has changed since 1994, however, when NASA's Jeff Ding brought the FSW process to the NASA agency. Although, at that time, FSW was little more than a "lab curiosity", NASA researchers started investigating where the FSW process would best fit NASA manufacturing programs. A laboratory FSW system was procured and the first welds were made in fall of 1995. The small initial investment NASA made into the first FSW system has certainly paid off for the NASA agency in terms of cost savings, hardware quality and notoriety. FSW is now a part of Shuttle External Tank (ET) production and the preferred weld process for the manufacturing of components for the new Crew Launch Vehicle (CLV) and Heavy Lift Launch Vehicle (HLLV) that will take this country back to the moon. It is one of the solid state welding processes being considered for on-orbit space welding and repair, and is of considerable interest for Department of Defense @OD) manufacturing programs. MSFC involvement in these and other programs makes NASA a driving force in this country's development of FSW and other solid state welding technologies. Now, a decade later, almost the entire on-going welding R&D at MSFC now focuses on FSW and other more advanced solid state welding processes
