Get PDFThis article aims to study the processes of instrumentationand instrumentalization information through theuse of ICT for the organization of collective work within anSME with only 20 workers as an adaptive response to a globalmarket context. We present a case study carried out in 2018in a small organization, with headquarters in Paris-France,specialized in mountmaking (soclage). We will focus on theuse of new communication and information technologies as atechnological infrastructure for the collective organization ofwork in order to meet a demand that may be local, regionalor global. The methods used in this study were specific to theergonomics of organizations, cognitive ergonomics and the digitalhumanities. From the clues of an organizational analysis, andwith the use of techniques of interviews, observation and dataanalysis, the activity of 20 workers was studied throughout theproductive mountmaking process, emphasizing the organizationof collective activity and arbitration processes that use digitaltools such as email, Google calendars and WhatsApp conversations.The results of the study show the preponderant role ofICTs as infrastructures for the dynamics of information typeartifacts that allow the organization of collective work whenit is dispersed in time and space, a recurrent aspect in theprovision of a service Worldwide. They also show how the use ofthese technologies generates virtual cooperation and negotiationspaces that facilitate arbitrations to face the demands of theactivity and facilitate the development of a collective of work. Byway of conclusion, we show how the cognitive technologies usedto study the use of digital tools, methods of natural languageprocessing, semantic analysis and classification of information,are a resource for the creation of adaptable and ergonomic toolsappropriate to the organization and its workers. This perspectivecan facilitate continuous improvement and human developmentwithin organizations.El presente articulo tiene el objetivo estudiar los procesos de instrumentación e instrumentalización de información a través del uso de TICs para la organización del trabajo colectivo en el seno de una PYME con tan solo 20 trabajadores como respuesta adaptativa a un contexto de mercado mundial.

La política de ciencia, tecnología e innovación y el retorno del Estado: 2007-2010, años de inestabilidad
Get PDFThis article analyzes the implementation process of the Ecuadorian science, technology and innovation policy (PCTI) within the framework of the beginning of the post-neoliberal period, which implied the strengthening of the State and the insertion of the paradigm of buen vivir. For this purpose, the novel elements in the definition of this policy under the framework of buen vivir are described as an introductory note. Then, the complex construction process of the explicit PCTI during these years is reviewed. Finally, the instruments implemented and their relationship with the definition of PCTI are analyzed. To this end, the concepts of explicit scientific policy and implicit scientific policy of Herrera [1] and the notion of scientific-technological paradigm of Velho[2] are used. The chosen approach is framed in the new institutionalism that understands the definition and implementation of the PCTI as the result of the strategic game of the actors involved in these processes. This case study uses investigation of historical archives, documentary analysis and indepth interviews with relevant actors. It is found that the PCTI during these years was unstable, as there were several short-term policy documents, and that its implementation was far from the ambitious rhetoric and the major objectives, limited to two instruments: international postgraduate scholarships and financing of research and development projects.En este artículo se analiza el proceso de implementación de la política de ciencia, tecnología e Innovación (PCTI) ecuatoriana en el marco del inicio del periodo postneoliberal, que implicó el fortalecimiento del Estado y la inserción del paradigma del buen vivir. Para ello, se describen, como nota introductoria, los elementos novedosos en la definición de esta política bajo el referencial del buen vivir. Luego, se reseña el complejo proceso de construcción de la PCTI explícita durante estos años. Finalmente, se analizan los instrumentos implementados y su relación con la definición de PCTI. Para ello se usan los conceptos de política científica explícita y política científica implícita de Herrera [1] y la noción de paradigma científico-tecnológico de Velho [2]. El enfoque elegido se enmarca en el nuevo institucionalismo, bajo el que la PCTI se entiende como el resultado del juego estratégico de los actores involucrados en estos procesos. Este estudio de caso usa investigación de archivos históricos, análisis documental y entrevistas en profundidad a actores relevantes. Se encuentra que la PCTI durante estos años fue inestable, pues existieron varios documentos de política de corta duración, y que su implementación estuvo lejos de la ambiciosa retórica y de los grandes objetivos planteados, limitándose a dos instrumentos: becas de posgrado en el extranjero y financiamiento de proyectos de investigación y desarrollo (I&D)
Regulación de la Neutralidad de Red en Sudamérica: Una revisión del progreso
Get PDFThe Internet is one of the most important technological innovations in human history. Nowadays, more than half of the global population is using Internet, and became the basis for the new Digital Economy. Although the Internet was created as a technology without a unique point of control, many actors have increased their efforts to control the infrastructure and traffic pursuing their own interests. In this scenario, with the changes driven by advances in technologies, services and the fast-growing of the Internet over the past two decades, the role of those who control the Internet infrastructure is one of the central issues of public debate about Internet policies. The main point of discussion is the Net Neutrality, that includes the access and control over content and applications without discrimination, the users and Internet service provider’s rights. This work analyzes how government authorities and stakeholders in four South American countries have approached the Net Neutrality debate between 2010 and 2017, also detail the particular conditions and characteristics of the situation that surround the creation and application of laws. The conclusions presents some problems and challenges that the countries should face in order to maintain the benefits of the policy.
Internet es una de las innovaciones tecnológicas más importantes en la historia humana. Actualmente, más de la de la mitad de la población global está usándola, y se ha convertido en la base para la nueva Economía Digital. Aunque la Internet fue creada como una tecnología sin un único punto de control, varios actores han aumentado sus esfuerzos para controlar la infraestructura y tráfico en base a sus intereses. En este escenario, con los cambios producidos por los avances en tecnología, servicios y la rápida penetración de Internet en las dos últimas décadas, el rol de aquellos que controlan la infraestructura de Internet es uno de los temas centrales del debate público sobre políticas de Internet. El principal punto de discusión es la Neutralidad de Red, que incluye el acceso y control sobre el contenido y aplicaciones sin discriminación, los derechos de los usuarios y proveedores de servicio. Este trabajo analiza como las autoridades gubernamentales y partes interesadas, en cuatro países de Sudamérica, han abordado el debate sobre Neutralidad de Red entre 2010 y 2017; además detalla las condiciones particulares y características de la situación alrededor de la creación y aplicación de las leyes. Las conclusiones presentan algunos problemas y retos que los países deberían afrontar con el objetivo de mantener los beneficios de las políticas.
