Les rationalisations du médium numérique

À partir d’observations personnelles sur l’importance de la technique et des technologies dans la production musicale, le projet de ce mémoire fut élaboré autour de la sociologie de la musique de Weber. En premier lieu, un questionnement du rapport entre musique, technologie et société permet d’établir de nombreuses voies pour la recherche concernant les médiations techniques de la musique. Ces médiations sont maintenant caractérisées par les changements issus de l’implantation de l’informatique dans de nombreuses sociétés et la modification des rapports de pouvoir et des rapports sociaux par les possibilités nouvelles offertes par le médium numérique. Si Internet semble avoir bouleversé l’industrie de la musique, de nouvelles possibilités de dépasser les limitations des technologies traditionnelles de la musique sont toutefois aussi apparues au sein de ce « système sociotechnique ». Ces modifications prennent la forme de philosophies, mais aussi de pratiques sociales qui se répandent, avant tout, auprès de la jeune génération, ce qu’il est possible d’observer par les changements dans les pratiques musicales. À partir des outils conceptuels de Weber, deux idéaltypes seront créés qui représentent autant de modes de diffusion de musique sur Internet. L’accent est mis sur la différence entre les pratiques sociales et musicales de ces modes de diffusions : l’un est basé sur des pratiques traditionnelles et greffé sur la nouvelle plateforme Internet, l’autre emprunte les caractéristiques de la diffusion de l’information en réseau caractéristique de la culture Internet et se caractérise par des pratiques dites réflexives. Ces idéaltypes, ainsi que les cas qui les constituent et qu’ils mettent en lumière, sont mis à profit pour discuter des motifs de l’action chez différents agents au cœur des pratiques de diffusion et, finalement, des modalités variées que prend la rationalisation de la diffusion de la musique à partir du médium numérique.

Estado del arte del control en sistemas organizacionales y técnicos

La perdurabilidad empresarial es una de las preocupaciones sectoriales, regionales y nacionales estudiada desde diferentes ámbitos (económico, social y académico), convirtiéndose en uno de los objetivos multinivel que impulsa el desarrollo y crecimiento de un país. De otro lado, una de las metodologías que está orientada a garantizar el cumplimiento de los objetivos o comportamientos planificados se denomina “sistemas de control” cuya aplicación es interdisciplinaria, tiene su origen en los sistemas técnicos y se traslada a los sistemas organizacionales. Este trabajo desarrolla una revisión bibliográfica del control, desde la en los sistemas técnicos y desde la Psicología, Sociología y disciplinas sociales a los sistemas organizacionales, identificando dos corrientes. La primera corriente, denominada “clásica” en sistemas causales y la segunda, llamada “inteligente”. El trabajo describe en cada corriente la conceptualización, los propósitos, las metodologías, la estructura, la taxonomía y las críticas en los sistemas de control. El control es abordado con diferentes metodologías, dependiendo de la corriente y de la naturaleza de cada sistema, pero tiene un propósito transversal o interdisciplinario que consiste en generar comportamientos esperados o deseables en el sistema, incluyendo alcanzar objetivos establecidos. En cuanto al desarrollo y comprensión, hay un mayor avance en los sistemas técnicos enfocados básicamente hacia la autonomía del sistema, mientras que en los sistemas organizacionales se ha generado la inquietud de evolucionar o generar controles diferentes o eliminar el control, pero las organizaciones continúan aplicando los controles clásicos y generando resultados de no perdurabilidad empresarial.

Bibliometría e historia de las prácticas académicas locales: un esbozo a partir del caso de la psicología en Colombia

A partir de un levantamiento longitudinal de información (1956-2008) sobre las publicaciones seriadas de psicología en Colombia se identifican una serie de variaciones en diversas características editoriales de éstas que a su vez se relacionan con reconfiguraciones del entramado institucional y de política pública en el que se desenvuelve la publicación local en psicología. En su conjunto, esta contribución argumenta que el aumento evidente de la productividad de la psicología nacional ha sido el resultado de este conjunto de transformaciones tanto del contexto social como de la revista concebida como producto editorial, como objeto técnico.

Innovation dynamics and capability in open collaborative cyber communities: implications for cybersecurity

Cybersecurity is a complex challenge that has emerged alongside the evolving global socio-technical environment of social networks that feature connectivity across time and space in ways unimaginable even a decade ago. This paper reports on the preliminary findings of a NATO funded project that investigates the nature of innovation in open collaborative communities and its implications for cyber security. In this paper, the authors describe the framing of relevant issues, the articulation of the research questions, and the derivation of a conceptual framework based on open collaborative innovation that has emerged from preliminary field research in Russia and the UK.

Building energy efficiency for sustainable development in China: challenges and opportunities

Rapid urbanisation in China has resulted in great demands for energy, resources and pressure on the environment. The progress in China's development is considered in the context of energy efficiency in the built environment, including policy, technology and implementation. The key research challenges and opportunities are identified for delivering a low carbon built environment. The barriers include the existing traditional sequential design process, the lack of integrated approaches, and insufficient socio-technical knowledge. A proposed conceptual systemic model of an integrated approach identifies research opportunities. The organisation of research activities should be initiated, operated, and managed in a collaborative way among policy makers, professionals, researchers and stakeholders. More emphasis is needed on integrating social, economic and environmental impacts in the short, medium and long terms. An ideal opportunity exists for China to develop its own expertise, not merely in a technical sense but in terms of vision and intellectual leadership in order to flourish in global collaborations.

A multidisciplinary literature review of low and zero carbon technologies into new housing

The UK Government is committed to all new homes being zero-carbon from 2016. The use of low and zero carbon (LZC) technologies is recognised by housing developers as being a key part of the solution to deliver against this zero-carbon target. The paper takes as its starting point that the selection of new technologies by firms is not a phenomenon which takes place within a rigid sphere of technical rationality (for example, Rip and Kemp, 1998). Rather, technology forms and diffusion trajectories are driven and shaped by myriad socio-technical structures, interests and logics. A literature review is offered to contribute to a more critical and systemic foundation for understanding the socio-technical features of the selection of LZC technologies in new housing. The problem is investigated through a multidisciplinary lens consisting of two perspectives: technological and institutional. The synthesis of the perspectives crystallises the need to understand that the selection of LZC technologies by housing developers is not solely dependent on technical or economic efficiency, but on the emergent ‘fit’ between the intrinsic properties of the technologies, institutional logics and the interests and beliefs of various actors in the housing development process.

The impact of information and communications technology on commercial real estate in the new economy

Purpose – This paper seeks to critically review the conceptual frameworks that have been developed for assessing the impact of information and communications technology (ICT) on real estate. Design/methodology/approach – The research is based on a critical review of existing literature and draws from examples of previous empirical research in the field. Findings – The paper suggests that a “socio-technical framework” is more appropriate to examine ICT impact in real estate than other “deterministic” frameworks. Therefore, ICT is an important part of the new economy, but must be seen in the context of a number of other social and economic factors. Research limitations/implications – The research is based on a qualitative assessment of existing frameworks, and by using examples from commercial real estate, assesses the extent to which a “socio-technical” framework can aid understanding of ICT impact. Practical implications – The paper is important in highlighting a number of the main issues in conceptualising ICT impact in real estate and also critically examines the emergence of a new economy in the information society within the general context of real estate. The paper also highlights research gaps in the field. Originality/value – The paper deconstructs the myths of the “death of real estate” and “productivity increase means jobs loss”, in relation to office real estate. Finally, it examines some of the ways in which ICT is impacting on real estate and suggests the most important components for a future research agenda in the field of ICT and real estate impact, and will be of value to property investors, facilities managers, developers, financiers, and others.

Large-scale atmospheric dynamics of the wet winter 2009–2010 and its impact on hydrology in Portugal

The anomalously wet winter of 2010 had a very important impact on the Portuguese hydrological system. Owing to the detrimental effects of reduced precipitation in Portugal on the environmental and socio-economic systems, the 2010 winter was predominantly beneficial by reversing the accumulated precipitation deficits during the previous hydrological years. The recorded anomalously high precipitation amounts have contributed to an overall increase in river runoffs and dam recharges in the 4 major river basins. In synoptic terms, the winter 2010 was characterised by an anomalously strong westerly flow component over the North Atlantic that triggered high precipitation amounts. A dynamically coherent enhancement in the frequencies of mid-latitude cyclones close to Portugal, also accompanied by significant increases in the occurrence of cyclonic, south and south-westerly circulation weather types, are noteworthy. Furthermore, the prevalence of the strong negative phase of the North Atlantic Oscillation (NAO) also emphasises the main dynamical features of the 2010 winter. A comparison of the hydrological and atmospheric conditions between the 2010 winter and the previous 2 anomalously wet winters (1996 and 2001) was also carried out to isolate not only their similarities, but also their contrasting conditions, highlighting the limitations of estimating winter precipitation amounts in Portugal using solely the NAO phase as a predictor.

City futures: exploring urban retrofit and sustainable transitions

Cities are responsible for up to 70% of global carbon emissions and 75% of global energy consumption. By 2050 it is estimated that 70% of the world's population will live in cities. The critical challenge for contemporary urbanism, therefore, is to understand how to develop the knowledge, capacity and capability for public agencies, the private sector and multiple users in city-regions (i.e. the city and its wider hinterland) to re-engineer systemically their built environment and urban infrastructure in response to climate change and resource constraints. To inform transitions to urban sustainability, key stakeholders' perceptions were sought though a participatory backcasting and scenario foresight process in order to illuminate challenging but realistic socio-technical scenarios for the systemic retrofit of core UK city-regions. The challenge of conceptualizing complex urban transitions is explored across multiple socio-technical ‘regimes’ (housing, non-domestic buildings, urban infrastructure), scales (building, neighbourhood, city-region), and domains (energy, water, use of resources) within a participatory process. The development of three archetypal ‘guiding visions’ of retrofit city-regional futures developed through this process are discussed, along with the contribution that such foresight processes might play in ‘opening up’ the governance and strategic navigation of urban sustainability.

Emerging segmentation practices in the age of the social customer

This paper reports on an exploratory study of segmentation practices of organisations with a social media presence. It investigates whether traditional segmentation approaches are still relevant in this new socio-technical environment and identifies emerging practices. The study found that social media are particularly promising in terms of targeting influencers, enabling the cost-effective delivery of personalised messages and engaging with numerous customer segments in a differentiated way. However, some problems previously identified in the segmentation literature still occur in the social media environment, such as the technical challenge of integrating databases, the preference for pragmatic rather than complex solutions and the lack of relevant analytical skills. Overall, a gap has emerged between marketing theory and practice. While segmentation is far from obsolete in the age of the social customer, it needs to adapt to reflect the characteristics of the new media.

A semiotic framework for information representation of energy consumption in office buildings

Taking a perspective from a whole building lifecycle, occupier's actions could account for about 50% of energy. However occupants' activities influence building energy performance is still a blind area. Building energy performance is thought to be the result of a combination of building fabrics, building services and occupants' activities, along with their interactions. In this sense, energy consumption in built environment is regarded as a socio-technical system. In order to understand how such a system works, a range of physical, technical and social information is involved that needs to be integrated and aligned. This paper has proposed a semiotic framework to add value for Building Information Modelling, incorporating energy-related occupancy factors in a context of office buildings. Further, building information has been addressed semantically to describe a building space from the facility management perspective. Finally, the framework guides to set up building information representation system, which can help facility managers to manage buildings efficiently by improving their understanding on how office buildings are operated and used.

An investigation of the required skills for the delivery of low and zero carbon buildings within a region

The United Kingdom is committed to a raft of requirements to create a low-carbon economy. Buildings consume approximately 40% of UK energy demand. Any improvement on the energy performance of buildings therefore can significantly contribute to the delivery of a low-carbon economy. The challenge for the construction sector and its clients is how to meet the policy requirements to deliver low and zero carbon (LZC) buildings, which spans broader than the individual building level, to requirements at the local and regional levels, and wider sustainability pressures. Further, the construction sector is reporting skills shortages coupled with the need for ‘new skills’ for the delivery of LZC buildings. The aim of this paper is to identify, and better understand, the skills required by the construction sector and its clients for the delivery of LZC buildings within a region. The theoretical framing for this research is regional innovation system (RIS) using a socio-technical network analysis (STNA) methodology. A case study of a local authority region is presented. Data is drawn from a review of relevant local authority documentation, observations and semi-structured interviews from one (project 1) of five school retrofit projects within the region. The initial findings highlight the complexity surrounding the form and operation of the LZC network for project 1. The skills required by the construction sector and its clients are connected to different actor roles surrounding the delivery of the project. The key actors involved and their required skills are: project management and energy management skills required by local authority; project management skills (in particular project planning), communication and research skills required by school end-users; and a ‘technical skill’ relating to knowledge of a particular energy efficient measure (EEM) and use of equipment to implement the EEM is required by the EEM contractors.

Perspectives on the specification of Building Integrated Photovoltaic (BIPV) technology in construction projects

Innovative, low carbon technologies are already available for use in the construction of buildings, but the impact of their specification on construction projects is unclear. This exploratory research identifies issues which arise following the specification of BIPV in non-residential construction projects. Rather than treating the inclusion of a new technology as a technical problem, the research explores the issue from a socio-technical perspective to understand the accommodations which the project team makes and their effect on the building and the technology. The paper is part of a larger research project which uses a Social Construction of Technology Approach (SCOT) to explore the accommodations made to working practices and design when Building Integrated PhotoVoltaic (BIPV) technology is introduced. The approach explores how the requirements of the technology from different groups of actors (Relevant Social Groups or RSG's) give rise to problems and create solutions. As such it rejects the notion of a rational linear view of innovation diffusion; instead it suggests that the variety and composition of the Relevant Social Groups set the agenda for problem solving and solutions as the project progresses. The research explores the experiences of three people who have extensive histories of involvement with BIPV in construction, looks at how SCOT can inform our understanding of the issues involved and identifies themes and issues in the specification of BIPV on construction projects. A key finding concerns the alignment of inflection points at which interviewees have found themselves changing from one RSG to another as new problems and solutions are identified. The points at which they change RSG often occurred at points which mirror conventional construction categories (in terms of project specification, tender, design and construction).

Mapping Educational Specialist knowHow (MESH): the building of a knowledge management system for research informed practice

In this invited article the authors present an evaluative report on the development of the MESHGuides project (http://www.meshguides.org/). MESHGuides’ objective is to provide education with an international knowledge management system. MESHGuides were conceived as research summaries for supporting teachers’ in developing evidence-based practice. Their aim is to enhance teachers’ capacity to engage actively with research in their own classrooms. The original thinking for MESH arose from the work of UK-based academics Professor Marilyn Leask and Dr Sarah Younie in response to a desire, which has recently gathered momentum in the UK, for the development of a more research-informed teaching profession and for the establishment of an on-line platform to support evidence-based practice (DfE, 2015; Leask and Younie 2001; OECD 2009). The focus of this article is on how the MESHGuides project was conceived and structured, the technical systems supporting it and the practical reality for academics and teachers of composing and using MESHGuides. The project and the guides are in the early stages of development, and discussion indicates future possibilities for more global engagement with this knowledge management system.

A história da gestão de produção e operações

Conhecer o passado ajuda a entender o presente e a preparar-se para o futuro. Atribui-se ao início do Século XIX a origem da área do conhecimento que mais tarde passou a ser conhecida como a gestão de produção e operações. Ao longo dos séculos XIX e XX, esta área evoluiu e mudou. Nasceu predominantemente industrial, passou a incorporar também a gestão de operações mais ligadas ao setor terciário da economia (os serviços), passou a contemplar também as redes de empresas que interagem (as redes de suprimentos). Passou por períodos de evolução acelerada (como durante a Segunda Grande Guerra Mundial) e passou por períodos de quase estagnação (como no período pós Guerra). Técnicas e conceitos surgiram, foram aperfeiçoadas, beberam da fonte de outras áreas do conhecimento (como as abordagens sócio-técnicas aproveitando-se de conceitos da psicologia e o controle de qualidade utilizando a estatística), vertentes surgiram, uniram-se, separaram-se numa fascinante dinâmica que até hoje não foi explicitada na forma de um texto que ajude os acadêmicos e profissionais práticos a entenderem melhor sua área. Este projeto pretende preencher esta lacuna: sistematizar um texto que descreve comentadamente a evolução da área de produção e operações. Além disso comenta sobre os impactos que a nova economia está trazendo para a área e especula sobre quais são as questões que deverão merecer desenvolvimento adicional de pesquisa e de práticas no futuro.
