Unanticipated Partial Behavioral Reflection: Adapting Applications at Runtime

Dynamic, unanticipated adaptation of running systems is of interest in a variety of situations, ranging from functional upgrades to on-the-fly debugging or monitoring of critical applications. In this paper we study a particular form of computational reflection, called unanticipated partial behavioral reflection, which is particularly well-suited for unanticipated adaptation of real-world systems. Our proposal combines the dynamicity of unanticipated reflection, i.e. reflection that does not require preparation of the code of any sort, and the selectivity and efficiency of partial behavioral reflection. First, we propose unanticipated partial behavioral reflection which enables the developer to precisely select the required reifications, to flexibly engineer the metalevel and to introduce the meta behavior dynamically. Second, we present a system supporting unanticipated partial behavioral reflection in Squeak Smalltalk, called Geppetto, and illustrate its use with a concrete example of a web application. Benchmarks validate the applicability of our proposal as an extension to the standard reflective abilities of Smalltalk.

New ruralities – old gender dynamics?: A reflection on high-value crop agriculture in the light of the feminisation debates

While a remarkable continuity in smallholder agricultural production has been identified, the shift from subsistence orientation towards more wage dependence appears in a different light when analysed under a gender perspective. "Feminisation" has been a catchphrase to characterise some of these processes; however, the debate has been subject to overgeneralisation, and can only inadequately grasp the gender dynamics in what has been referred to as "new ruralities". Illustrated for high-value crop production as an expression of agricultural transition in the Global South, this contribution offers a critical account of the feminisation thesis. Instead of discarding the notion of feminisation, it advocates a reassessment of its potential as a comprehensive framework against which empirical findings can be reflected. While conventional uses of the feminisation thesis have, in their great majority, come up with the conclusion that for women it can always only get worse, I propose a perspective which reveals gains and risks and how they are shared between men and women as they engage in new agricultural labour markets. This perspective rests on a methodology for case-based, comparative studies developed in this paper as a contribution for assessing the nature of agricultural transition and to investigate the qualitative change associated with new ruralities. A distinctive appreciation of the substance of agricultural change for different members of the rural society – namely men and women, but also different men, and different women – is the premise for overcoming barriers to shared development, and for framing effective governance in the context of global development.

A unique behavior of sub-critical hydrocarbon permeability in activated carbon at low pressures

In our study on sub-critical hydrocarbon permeation in activated carbon, a minimum in the total permeability (B-T) at low pressure has been observed for only long-chain hydrocarbons such as n-hexane and n-heptane. Such an observation suggests that the minimum appearance depends on the properties of permeating vapors as well as the porous medium. In this paper a permeation model is presented to explain the minimum behavior with the allowance of the collision-reflection factor in the Knudsen diffusivity to be a function of surface loading. Surface diffusion was found to be very significant compared to other transport mechanisms such as Knudsen diffusion and gaseous viscous flow at low pressures. Since the gaseous viscous flow contributes negligibly to the B, at low pressures, the minimum appearance in the B, is mainly attributed to the interplay between Knudsen diffusion and surface diffusion. Also, the molecular structure of adsorbates plays an important role in the minimum appearance.

Reflective analysis: Techniques for facilitating reflection

This paper describes a number of techniques for facilitating reflective critical analysis as a means of eliciting in-depth reflections on practice. The authors have previously used similar techniques in the research context, to assist practitioners to identify and analyse the basis of their work with clients. The techniques presented in this paper have been adapted for use in social work education, including in class-based and field education contexts, and to professional supervision.

Positionality and Comparisons: Critical Views on Qualitative Research across Asia

Ce cahier est basé sur la réflexion autobiographique de deux chercheuses ayant effectué des recherches qualitatives et ethnographiques, de 2008 à 2014, en Asie centrale et du Sud-­‐Est. Les expériences sur le terrain constituent des moyens de comparaisons dans le présent document. En mettant l’accent sur le positionnement sur le terrain, l’étude montre que, d’abord, il est essentiel de détenir une poste intermédiaire et de parler une langue locale afin de garantir un accès et de mener des activités de recherche sur le terrain. Deuxièmement, différentes régions prédéterminent des contextes culturels et politiques ponctuels qui, à leur tour, façonneraient la recherche en sciences sociales. Troisièmement, le fait d’être une femme présente à la fois des avantages et des inconvénients. Enfin, en termes de méthodologie, les stages et les entrevues se sont avérés des méthodes fiables pour la collecte des données empiriques sur les régions ci-­‐dessus mentionnées, sans pour autant permettre de bâtir la confiance.

Critical incident analysis: reflections of a teacher educator

As a teacher educator I consider myself an advocate for research-informed education, and strongly believe that it starts with one’s own critical self-reflection and analysis of one’s own teaching practice. Critical incident analysis is a pedagogical theory developed by Tripp (1993), whose analytical approaches allow reflection on teaching situations – ‘the critical incident’ – so that teachers can develop their professional judgments and practices. This article examines the concept of critical incident analysis through a teaching situation, with the aim of improving the teaching practice of students on teacher education programmes. I conclude that although critical incident analysis is a useful tool in navigating teaching practices, often challenges need to be addressed at much broader levels than the teaching context itself.

Design as a critical research

Historically the imaginary and the hegemonic thinking, in the Western globe north, has been marked by the epistemology and capitalists archetypes. Notwithstanding the design seem as a practice and discipline shielded on a simplistic discourse of functional / communicative efficiency, wandering through by multiple aestheticism apparently neutral in relation to the symbolic, but in fact they never are, because what really hapens is that the aesthetic appearance of the generated forms will always be a review of the powers ruling. We start from the understanding that the act of creating an aesthetic artifact, will also be a movement of inscription in a discursive platform (that precedes it), is in itself an narrative act and that fact represent a certain take place in relation to certain symbolic reality. On reflection shown if it sees design as a discipline and / or an instrument of action, whose operational relevance tends to question and simultaneously rehearsing a response, in which more than why interests answer to why. Apparently the design is a content mediator, but also, it is structure, is body, is idea. We think a design praxis as discipline and enrollment tool of critical thought and social transformation. For guiding research in this text, we propose the following question: Can the Design want for themselves an engagement with the symbolic in order to be an active part in the production of critical thinking in the place where it belongs? Methodologically our argument will be present in two differents moments: 1. a first, exploratory nature where we rescue the draw issues in the practice of design and 2. a second analytical nature concerning the subject issues (graphic and / or utility ) design and how it incorporates formal rites, political events and social practices of contemporary everyday life. We consider the praxis of design as a discipline and critical thinking enrollment tool as agents of social transformation. With this study we seek for contribute phenomenology design by studying the artifacts of configuration as well as the possible messages they convey and what impact they may have on the social network.

Homophobia and the oppressive naturalized practice: A critical discourse analysis.

This paper seeks to analyze the statements of a teacher of basic education in the city of Cocalinho-MT on homosexuality. I try to identify possible ideological traits through the theoretical framework of Critical Discourse Analysis (Fairclough, 2003a), with support from Systemic Functional Linguistics (Halliday, 1994). The analytical categories used are representational meaning, interdiscursivity and ideational metafunction. The studies of Rios (2009), Louro (2000, 2010) and Borrillo (2009) are used for the conceptualization of issues related to gender, sexuality and homophobia. The results show the presence of discourses that contribute to the strengthening of homophobia as oppressive naturalized practice, as the silencing of diversity discourse, the heteronormative and the nuclear family discourse. I make a reflection, to deconstruct these discourses that we educators can take advantage of rights and duties without hiding in a heteronormative profile for fear of suffer with the physical and psychological prejudice.

Autoethnography : critical appreciation of an emerging art

In this article, the author discusses how she applied autoethnography in a study of the design of hypermedia educational resources and shows how she addressed problematic issues related to autoethnographic legitimacy and representation. The study covered a 6-year period during which the practitioner’s perspective on the internal and external factors influencing the creation of three hypermedia CD-ROMs contributed to an emerging theory of design. The author highlights the interrelationship between perception and reality as vital to qualitative approaches and encourages researchers to investigate their reality more fully by practicing the art of autoethnography.
