ARX, model thinking: taxonomy and operativity of an architectural process

The purpose of this work was to establish a taxonomy of hand made model construction as a platform for an approach to project an operative method in architecture. It was therefore studied and catalogued in a systematic approach a broad model production in the work of ARX. A wide range of families and sub-families of models were found, with different purposes according to each phase of development, from searching steps for a new possible configuration to detailed refined decisions. This working method revealed as most relevant characteristics, the grounds for a potential personal reflection and open discussion on project method, its flexibility on space modeling, an accuracy on the representation of real construction situations and its constant and stimulating opening to new suggestions. This research helped on a meta-reflection about this method, having been useful on creating a consciousness of processes that pretend to become an autonomous language, knowledge that might become useful to those who pretend to implement a haptic modus operandi in the work of an architectural project.

Virus-Resistance Genes: The Mouse Model

Os Homens e os animais diferem grandemente nas suas respostas às infecções virais. Os vírus podem induzir, em alguns, sintomas ligeiros, enquanto que em outros podem provocar patologias graves mesmo mortais. Acumulam-se evidências que o património genético é um dos factores primordiais a condicionar e contribuir para a complexidade das interações vírus-hospedeiro. A identificação de genes com papel na resposta à infecção viral tornouse pois o tema de investigação de muitos laboratórios, com o objectivo de elucidar os processos fisiopatológicos que regem e determinam esse tipo de resposta. Neste artigo de revisão pretende-se ilustrar como o modelo murino têm sido utilizado para a identificação de genes de resistência viral, e como estes podem funcionar como base para a descoberta de genes homólogos em outras espécies. na elucidação dos mecanismos de resistência, e em novos componentes da reunir todos os genes de resistência viral descobertos em murganhos.

A System Dynamics-Based Simulation Experiment for Testing Mental Model and Performance Effects of Using the Balanced Scorecard

This study develops a theoretical model that explains the effectiveness of the balanced scorecard approach by means of a system dynamics and feedback learning perspective. Presumably, the balanced scorecard leads to a better understanding of context, allowing managers to externalize and improve their mental models. We present a set of hypotheses about the influence of the balanced scorecard approach on mental models and performance. A test based on a simulation experiment that uses a system dynamics model is performed. The experiment included three types of parameters: financial indicators; balanced scorecard indicators; and balanced scorecard indicators with the aid of a strategy map review. Two out of the three hypotheses were confirmed. It was concluded that a strategy map review positively influences mental model similarity, and mental model similarity positively influences performance.
