Knowledge practices in design: The role of visual representations as 'epistemic objects'

We use a detailed study of the knowledge work around visual representations to draw attention to the multidimensional nature of `objects'. Objects are variously described in the literatures as relatively stable or in flux; as abstract or concrete; and as used within or across practices. We clarify these dimensions, drawing on and extending the literature on boundary objects, and connecting it with work on epistemic and technical objects. In particular, we highlight the epistemic role of objects, using our observations of knowledge work on an architectural design project to show how, in this setting, visual representations are characterized by a `lack' or incompleteness that precipitates unfolding. The conceptual design of a building involves a wide range of technical, social and aesthetic forms of knowledge that need to be developed and aligned. We explore how visual representations are used, and how these are meaningful to different stakeholders, eliciting their distinct contributions. As the project evolves and the drawings change, new issues and needs for knowledge work arise. These objects have an `unfolding ontology' and are constantly in flux, rather than fully formed. We discuss the implications for wider understandings of objects in organizations and for how knowledge work is achieved in practice.

Performing traditional knowledge using a game engine: Communicating and sharing Australian Aboriginal knowledge practices

This paper challenges current practices in the use of digital media to communicate Australian Aboriginal knowledge practices in a learning context. It proposes that any digital representation of Aboriginal knowledge practices needs to examine the epistemology and ontology of these practices in order to design digital environments that effectively support and enable existing Aboriginal knowledge practices in the real world. Central to this is the essential task of any new digital representation of Aboriginal knowledge to resolve the conflict between database and narrative views of knowledge (L. Manovich, 2001). This is in order to provide a tool that complements rather than supplants direct experience of traditional knowledge practices (V. Hart, 2001). This paper concludes by reporting on the recent development of an advanced learning technology that addresses this.

Knowledge and practices of medical students to prevent tuberculosis transmission in Rio de Janeiro, Brazil

Objectives. To describe knowledge, practices, and associated factors of medical students to prevent transmission of tuberculosis (TB) in five medical schools. Methods. Cross-sectional survey of undergraduate medical students in preclinical and in early and late clinical years. Information was obtained on sociodemographic profile, previous lectures on TB, knowledge about TB transmission, exposure to patients with active pulmonary TB, and use of respiratory protective masks. Results. Among 1 094 respondents, 575 (52.6%) correctly answered that coughing, speaking, and sneezing can transmit TB. Early [adjusted odds ratio = 4.0 (3.0, 5.5)] and late [adjusted odds ratio = 4.2 (3.1, 5.8)] clinical years were associated with correct answers, but having had previous lectures on TB was not. Among those who had previous lectures on TB, the rate of correct answers increased from 42.1% to 61.6%. Among 332 medical students who reported exposure to TB patients, 194 (58.4%) had not used protective masks. More years of clinical experience was associated with the use of masks [adjusted odds ratio = 2.9 (1.4, 6.1)], while knowledge was inversely associated with the use of masks [adjusted odds ratio = 0.4 (0.2, 0.6)]. Conclusions. Many medical students are not aware of the main routes of TB infection, and lectures on TB are not sufficient to change knowledge and practices. Regardless of knowledge about TB transmission, students engage in risky behaviors: more than two-thirds do not use a protective mask when examining an active TB case. We suggest innovative, effective active learning experiences to change this scenario.

Dengue in Brazil and Colombia: a study of knowledge, attitudes, and practices

Introduction This study was conducted in Brazil and Colombia,where dengue is endemic and vector control programs use chemical insecticides. Methods We identified knowledge, attitudes, and practices about dengue and determined the infestation levels of Aedes aegypti in one Brazilian and four Colombian communities. Results The surveys show knowledge of the vector, but little knowledge about diagnosis, prognosis, and treatment. Vector infestation indices show Brazil to have good relative control, while Colombia presents a high transmission risk. Conclusions Given the multidimensionality of dengue control, vertical control strategies are inadequate because they deny contextualized methods, alternative solutions, and local empowerment.

Knowledge management in higher education institutions: a framework to improve collaboration

The purpose of this paper is to present a framework that increases knowledge sharing and collaboration in Higher Education Institutions. The paper discusses the concept of knowledge management in higher education institutions, presenting a systematization of knowledge practices and tools to linking people (students, teachers, researchers, secretariat staff, external entities)and promoting the knowledge sharing across several key processes and services in a higher education institution, such as: the research processes, learning processes, student and alumni services, administrative services and processes, and strategic planning and management. The framework purposed in this paper aims to improve knowledge practices and processes which facilitate an environment and a culture of knowledge collaboration,sharing and discovery that should characterize an institution of higher education.

Database and narratological representation of Australian Aboriginal knowledge as information visualisation using a game engine

Current database technologies do not support contextualised representations of multi-dimensional narratives. This paper outlines a new approach to this problem using a multi-dimensional database served in a 3D game environment. Preliminary results indicate it is a particularly efficient method for the types of contextualised narratives used by Australian Aboriginal peoples to tell their stories about their traditional landscapes and knowledge practices. We discuss the development of a tool that complements rather than supplants direct experience of these traditional knowledge practices.

Las visiones y los mundos: depredación, transformación y equilibrio en discursos de la Amazonía occidental

Ce travail se veut d’un rapprochement aux pratiques et savoirs des peuples amazoniens à partir de discours produits par ces nations. Nous y interpréterons des chants sacrés, des narrations ancestrales et des textes académiques de penseurs autochtones. Ce travail indique que les pratiques amazoniennes s’inscrivent dans un contexte de significations qui considèrent que tout être vivant possède des pensées et un esprit; qu’il existe des êtres spirituels qui défendent ces êtres vivants contre les abus possibles. Les êtres humains doivent transcender leur état de conscience, se déplacer vers les mondes invisibles et initier la communication avec ces esprits, pour ainsi maintenir l’équilibre existentiel. Selon les pensées de l’Amazonie, les communautés humaines ne peuvent pas se concevoir comme autosuffisantes; elles doivent plutôt maintenir de constantes relations avec les multiples êtres qui peuplent leur environnement visible et les mondes invisibles. Les trois concepts clés qui permettent de rendre compte des pratiques des peuples amazoniens sont la déprédation, la transformation et l’équilibre. Par déprédation, nous entendons les pratiques amazoniennes qui impliquent une destruction des autres êtres afin de sustenter la vie de la communauté. Selon les pensées de l’Amazonie, cette déprédation devrait être mesurée, dans le but de ne pas tuer plus que nécessaire à la survie. La déprédation est régulée par les êtres spirituels. Les pratiques amazoniennes de transformation sont destinées à la sauvegarde des liens de la communauté, en transfigurant tout ce qui entre ou sort de cette dernière, de manière à ce qu’aucun agent externe ne mette en péril les liens affectifs. Les pratiques de déprédation et de transformation sont complémentaires et elles requièrent toutes les deux de se produire de manière équilibrée, en respectant les savoirs ancestraux et les lois cosmiques établies par les esprits supérieurs. En ce qui a trait à la méthode d’analyse, nous aborderons les discours de l’Amazonie à partir leur propre logique culturelle, sans imposer des méthodologies préétablies, ce qui donne comme résultat un travail académique qui approfondie la production intellectuelle interculturelle, puisque ce sont les voix indigènes qui expriment elles-mêmes leurs conceptions et le sens de leurs pratiques. Dans son ensemble, le travail engage un dialogue critique avec son champ d’étude en discutant ou en approfondissant certaines conceptions forgées par la littérature anthropologique consacrée à l’étude de la région, à partir des savoirs ancestraux amazoniens qui nourrissent les pratiques de ces nations.

When glaciers vanish : nature, power and moral order in the indian Himalayas

La présente thèse est une étude ethnographique qui examine le savoir en tant que pratique située au Ladakh, dans l’Himalaya indien. Elle analyse les implications socioculturelles des deux moteurs de changement en jeu au Ladakh: l’un est d'origine socio-économique et lié à la production du Ladakh en tant que zone frontalière, tandis que l’autre est de nature environnementale et entrainé par les changements climatiques. Alors que le Ladakh est demeuré hors de la portée de l’État bureaucratique pendant l’administration coloniale britannique, la région s’est trouvée reconfigurée en zone frontalière stratégique après l’indépendance de l’Inde des suites des guerres successives avec le Pakistan et la Chine. L’Indépendance a mené à la partition de l’Inde et du Pakistan en 1947; cette thèse examine la portée à long terme des évènements traumatisants de la partition tels qu’ils se sont déroulés au Ladakh et comment les Ladakhis établissent des liens entre ces évènements et les changements climatiques. L’État indien s’est produit dans la région à travers une volonté de dominer les montagnes, principalement par le développement d’infrastructures et par l’intégration du savoir local des Ladakhis dans l’appareil militaire. La militarisation a restructuré l'économie du Ladakh, redéfini la structure des ménages, contribué à l’exode rural, déplacé la centralité des activités agropastorales et, tel que la dissertation le soutient, altéré de manière significative la connexion de la population locale avec l'environnement. La rationalisation croissante de la perspective sur l’environnement aujourd'hui contribue à la fragmentation des liens qui unissent les domaines naturels et humains dans la cosmologie locale de même qu’à l'abandon des pratiques rituelles connexes. Parallèlement, la région est touchée par des effets distincts des changements climatiques, en particulier la récession des glaciers. La thèse juxtapose l'expérience subjective de ces vastes changements dans la vie quotidienne des villageois de la Vallée de Sham avec les faits historiques environnementaux, démontrant ainsi que les événements historiques locaux influent sur les perceptions des changements environnementaux. L'analyse démontre qu’un phénomène objectif tel que la récession des glaciers est interprété à travers des réalités locales. Plus précisément, selon la conception du monde locale, un glacier en retrait est une figure rhétorique d’une transformation de la condition humaine. Comme le fait valoir la dissertation, l’interprétation culturelle ne constitue pas un obstacle à l'objectivité de l'histoire naturelle de la cosmologie locale. L’interprétation culturelle et l'expérience empirique s’avèrent par ailleurs essentielles à la vitalité des connaissances locales sur l'environnement et à la performance des pratiques associées.

Visual representations as 'artifacts of knowing'

How does the manipulation of visual representations play a role in the practices of generating, evolving and exchanging knowledge? The role of visual representation in mediating knowledge work is explored in a study of design work of an architectural practice, Edward Cullinan Architects. The intensity of interactions with visual representations in the everyday activities on design projects is immediately striking. Through a discussion of observed design episodes, two ways are articulated in which visual representations act as 'artefacts of knowing'. As communication media they are symbolic representations, rich in meaning, through which ideas are articulated, developed and exchanged. Furthermore, as tangible artefacts they constitute material entities with which to interact and thereby develop knowledge. The communicative and interactive properties of visual representations constitute them as central elements of knowledge work. The paper explores emblematic knowledge practices supported by visual representation and concludes by pinpointing avenues for further research.

Introduction: the policy trajectory of Fair Trade

It focuses on policy practice as a dynamic process, highlighting the changing configurations of actors, policy spaces, knowledge, practices and commodities that are shaping the policy trajectory of fair trade. It highlights how recent literature has tackled questions of mainstreaming as part of this trajectory, bringing to the fore dimensions of change associated with the market, state and civil society.

Avaliação de intervenção educativa sobre aleitamento materno dirigida a agentes comunitários de saúde

OBJETIVOS: avaliar ação educativa visando à capacitação de agentes comunitários de saúde em promoção e apoio ao aleitamento materno. MÉTODOS: estudo do processo e adequação de intervenção, com comparação de conhecimentos e práticas de 54 agentes, antes e dois meses após a ação. A intervenção, quatro oficinas teórico-práticas com oito horas cada, fundamentou-se em princípios da Educação Crítico-Reflexiva e em dois cursos de capacitação de equipes de maternidade. Os resultados foram expressos pelas diferenças dos escores médios de conhecimentos, práticas e total, adotando-se p<0,05 como nível crítico. RESULTADOS: houve aumento do escore médio de conhecimentos (21,0 para 26,6; p<0,001) e de escores de conhecimentos classificados como bons (37,0% para 88,8%, p<0,001). Não houve mudanças no escore de participação dos agentes em específicas ações de saúde, como grupos. O efeito da intervenção mais apontado pelos agentes foi sentir-se mais aceito e em melhores condições de participar da equipe multiprofissional em situações envolvendo cuidados com crianças. Mais da metade relatou melhora na qualidade e quantidade das orientações prestadas nas visitas domiciliarias. CONCLUSÕES: a intervenção tem efeitos positivos sobre conhecimentos e a prática dos agentes junto às famílias, mas não promove aumento da sua participação em específicas ações de saúde.
