La raza y la lengua como capital en las escuelas : una propuesta sociológica para las reformas en educación lingüística

Este texto hace un acercamiento sociológico al análisis de la raza y la lengua en la formación de programas de educación en idiomas. Este enfoque usa los modelos de Bourdieu de habitus y campo social, los cuales enmarcan la raza y la lengua como elementos variables en el cambio educativo y pedagógico, que están, a la vez, sujetos a la agenciamiento de profesores y estudiantes. El enfoque sugiere que una política de educación en lenguas para la justicia social puede concentrarse no sólo en el cambio y el desarrollo del sujeto humano, sino también en cambio sistemático de los campos sociales del currículo.

The application of social network analysis in the construction industry of Hong Kong

The Hong Kong construction industry is currently facing ageing problem and labour shortage. There are opportunities for employing ethnic minority construction workers to join this hazardous industry. These ethnic minority workers are prone to accidents due to communication barriers. Safety communication is playing an important role for avoiding the accidents on construction sites. However, the ethnic minority workers are not very fluent in the local language and facing safety communication problems while working with local workers. Social network analysis (SNA), being an effective tool to identify the safety communication flow on the construction site, is used to attain the measures of safety communication like centrality, density and betweenness within the ethnic minorities and local workers, and to generate sociograms that visually represent communication pattern within the effective and ineffective safety networks. The aim of this paper is to present the application of SNA for improving the safety communication of ethnic minorities in the construction industry of Hong Kong. The paper provides the theoretical background of SNA approaches for the data collection and analysis using the software UCINET and NetDraw, to determine the predominant safety communication network structure and pattern of ethnic minorities on site.
