Towards a codification of practical knowledge

As practical knowledge seems to have a central place in organisational issues, we focus on possibilities of studying and formalising it. From an unusual theoretical perspective, we view practical knowledge as embodied knowing that is only manifest through action in a particular situation. Although this knowledge is largely implicit, we try to make what is articulable explicit. After highlighting the stakes involved in the codification of practices, we review the ontological and epistemological assumptions underlying the method developed. The method is founded on participant observation, a video recording of a situated subjective perspective and an ex post interview using this perspective to aid an actor in making part of his/her practical knowledge explicit. We present its implementation within research on polar expeditions in order to understand how an experienced actor deals with risks. In conclusion, we point out (1) the importance of this kind of data in knowledge management, (2) some lines of further research.     

Bio-electrospraying and aerodynamically assisted bio-jetting whole human blood: Interrogating cell surface marker integrity

Bio-electrospraying and aerodynamically assisted bio-jetting are two direct cell handling approaches recently pioneered, which have demonstrated significant applicability to the life sciences. These two bioprotocols have undergone scientific rigor, which have seen these techniques been explored in conjunction with a wide range of immortalized, primary and stem cells, and those whole organisms. Those studies have demonstrated a cellular population of >70% viable post-treatment in comparison with controls. Although, these studies assessed cellular viability, cell surface molecules play a critical role in several cellular functions, in particular, have importance to tissue engineering and regenerative medicine. Thus, in the studies reported herein, we demonstrate post-treated viable cells retain their cell surface marker expression levels in comparison to controls, over both short and long time points. Therefore, these studies further push back the frontiers of both bio-electrosprays and aerodynamically assisted bio-jetting in their endeavor as novel strategies for tissue engineering and regenerative biology∕medicine with possible targeted clinical utility.     

Educating Art in a Globalizing World. The University of Ideas: A Sociological Case‐study

In 1999, the Italian Arte Povera artist Michelangelo Pistoletto and other artists laid the foundations of The University of Ideas (UNIDEE), an exceptional international artist‐in‐residence programme with a strong ideological foundation. As a sociologist of culture I had the opportunity to do research in the huge organization for a month by doing participant observation, in‐depth interviews and discourse analysis. In this article the educational programme of UNIDEE is interpreted in sociological terms. First of all it will be contextualized in the artistic work of Michelangelo Pistoletto through his concept of the mirror and his a‐modern idea of ‘The Minus Artist’. In the second part Pistoletto's artistic, political and economic movement Cittadellarte, in which UNIDEE is based, will be described. Finally UNIDEE will be analysed as a model for art education on the border of modernity attempting to redefine the position of art and of the artist in a globalizing world.     

The impact of significant others’ actual appraisals on children’s self-perceptions: What about Cooley’s assumption for children?

The aim of this paper was to study the construction of children’s self-perception relying on Cooley’s hypothesis. More precisely, we were interested in the mediation effect of significant others’ actual appraisal on self-perception by the perception of others’ actual appraisal (i.e., reflected appraisal). First, we argued that this mediation effect would occur in the domains where children have feedback from significant others (here teacher or parents). Second, we took into account two measures of reflected appraisal: reflected appraisal assessed in a classic fashion and appraisal social support assessed with Harter’s scale (1985b). We argued that reflected appraisal assessed in a classic fashion would be a better mediator of the effect of actual appraisal on self-perception by reflected appraisal in comparison to appraisal social support. In order to test these hypotheses, we conducted a study with 126 children (age 8–9), 106 parents and six teachers. The results, taken as a whole, support these hypotheses.     

Finite Element Analysis of Reinforced Concrete Plate Impacted by Block

A new concept of structurally dissipating rock-shed (SDR) was developed by the lab of Tonello IC and LOCIE-ESIGEC (France). To decide the dimension of the plate used in SDR, an ANSYS model which could simulate the impact of rock in the centre of the plate was established by Fabien Delhomme. By using this model, some finite element analyses are carried out in the present paper. Firstly, a plate impacted by a block is numerically simulated, the numerical results obtained from different mesh sizes are compared and the accuracy of the finite element model is verified. Then, the dynamic response of the plate impacted at the boundary and in the medium part is computed. By analyzing the stress in rebar, the most dangerous region of impact of plate was found. For a rectangular plate, the most dangerous region is at the corner of the plate when a block drops in. Finally, the whole deformation process of the plate under dropping block was simulated and a simplified definition (effect zone) to describe the deformation process in different positions of plate was given. From this study, it is found that the impact only affects heavily within the effect zone.     

The effect of elevating the heels on spinal kinematics and kinetics during the back squat in trained and novice weight trainers

ABSTRACT

This research assessed the influence of various heel elevation conditions on spinal kinematic and kinetic data during loaded (25% and 50% of body weight) high-bar back squats. Ten novice (mass 67.6 ± 12.4 kg, height 1.73 ± 0.10 m) and ten regular weight trainers (mass 66.0 ± 10.7 kg, height 1.71 ± 0.09 m) completed eight repetitions at each load wearing conventional training shoes standing on the flat level floor (LF) and on an inclined board (EH). The regular weight training group performed an additional eight repetitions wearing weightlifting shoes (WS). Statistical parametric mapping (SPM1D) and repeated measures analysis of variance were used to assess differences in spinal curvature and kinetics across the shoe/floor conditions and loads. SPM1D analyses indicated that during the LF condition the novice weight trainers had greater moments around L4/L5 than the regular weight trainers during the last 20% of the lift (P < 0.05), with this difference becoming non-significant during the EH condition. This study indicates that from a perspective of spinal safety, it appears advantageous for novice weight trainers to perform back squats with their heels slightly elevated, while regular weight trainers appear to realize only limited benefits performing back squats with either EH or WS.     

The Rise of Computing Research in East Africa: The Relationship Between Funding,Capacity and Research Community in a Nascent Field

The emergence of vibrant research communities of computer scientists in Kenya and Uganda has occurred in the context of neoliberal privatization, commercialization, and transnational capital flows from donors and corporations. We explore how this funding environment configures research culture and research practices, which are conceptualized as two main components of a research community. Data come from a three-year longitudinal study utilizing interview, ethnographic and survey data collected in Nairobi and Kampala. We document how administrators shape research culture by building academic programs and training growing numbers of PhDs, and analyze how this is linked to complicated interactions between political economy, the epistemic nature of computer science and sociocultural factors like entrepreneurial leadership of key actors and distinctive cultures of innovation. In a donor-driven funding environment, research practice involves scientists constructing their own localized research priorities by adopting distinctive professional identities and creatively structuring projects. The neoliberal political economic context thus clearly influenced research communities, but did not debilitate computing research capacity nor leave researchers without any agency to carry out research programs. The cases illustrate how sites of knowledge production in Africa can gain some measure of research autonomy, some degree of global competency in a central arena of scientific and technological activity, and some expression of their regional cultural priorities and aspirations. Furthermore, the cases suggest that social analysts must balance structure with culture, place and agency in their approaches to understanding how funding and political economy shape scientific knowledge.     

Impact of teachers’ implicit theories and perceived pressures on the establishment of an autonomy supportive climate

According to self-determination theory, when teachers establish an autonomy supportive climate in the classroom, students demonstrate high levels of self-determination and are intrinsically motivated. The aim of this study was to identify factors leading teachers (N=336) to report that they create such a climate. We conducted a path analysis in order to examine the respective roles of teachers’ implicit theories, their seniority, and their perceptions of pressures at work. We also attempted to find out whether these personal and contextual variables have a direct influence or are mediated by teachers’ self-efficacy. Our first finding was that a theory of academic ability as a fixed trait caused a drop in the teachers’ reported support for autonomy. On the other hand, the belief that academic abilities can be improved through students’ own efforts indirectly favored an autonomy supportive climate by acting positively on the teachers’ self-efficacy. Also, seniority had a significant positive effect on autonomy support that was direct, but was also mediated by self-efficacy. Finally, perceived pressures had a negative impact on reported autonomy support, but their influence was also mediated by self-efficacy.     

Learning the norm of internality: NetNorm,a connectionist model

The objective of the present article is to show that connectionist simulations can be used to model some of the socio-cognitive processes underlying the learning of the norm of internality. For our simulations, we developed a connectionist model which we called NetNorm (based on Dual-Network formalism). This model is capable of simulating the implicit learning of this social norm through a simple process of situation/reinforcement association. In a second simulation, we simulated a non-linear learning in order to reproduce the triple inflexion in the internality learning curve that has been observed for children entering high school. The results support those previously reported in the literature. Moreover, our simulations could be used to develop new experimental predictions.
