- ItemLearning to collaborate by collaborating: a face-to-face collaborative activity for measuring and learning basics about teamwork(WILEY, 2009) Cortez, C.; Nussbaum, M.; Woywood, G.; Aravena, R.In today's fast-changing business environment, teams have emerged as a requirement for business success. However, in schools and universities, students are usually not taught teamwork skills. In this paper, we introduce learning to collaborate by collaborating, a process that enables collaboration and teamwork skills to be taught and measured through face-to-face collaborative work and class-wide activities supported by wirelessly connected hand-held devices. Following a description of learning to collaborate by collaborating, we present an experimental study whose results demonstrate that participants in the process displayed improved teamwork performance. We conclude that it is possible to effectively teach collaboration skills through the use of immediate feedback provided by a supporting technology.
- ItemSnowpack retaining techniques in the avalanche starting zones(PONTIFICIA UNIV CATOLICA CHILE, ESCUELA CONSTRUCCION CIVIL, 2010) Castro, D.; Jose Pedro Mery, J P; Aravena, R.; Sanhueza, C.Snow avalanches are events often involving serious risk to human beings and goods due to their destructive power This is why effective control measures are required to mitigate the risk for human settlements, goods and services on mountain slopes or at the foot of avalanche ways. This article summarizes the different structural systems and techniques used nationally and internationally to support and stabilize the snowpack in avalanche starting zones. These measures act by reducing the pressures originated by the creeping and sliding of the snowpack. While the current state of the art and the control systems implementation have been mainly developed in Europe, the prevention measures by modern supporting structures have been carried out in Chile since the 80s.
