A clinical examination survey included 600 women and men between 18 and 22 years of age studied for the possible association between temporomandibular disorders and a number of occlusal parameters (Angle's classification, type of eccentric occlusion, chewing side preference, horizontal overlap value, and non-working side contact occurrence. Extraoral and intraoral examination was performed for ...

How learning occurs within Free/Libre Open Source (FLOSS) communities and what is the dynamics such projects (e.g. the life cycle of such projects) are very relevant questions when considering the use of FLOSS projects in a formal education setting. This paper introduces an approach based on the 3C collaboration model (communication, coordination and cooperation) to represent the collaborative ...

There is a lot of research anticipating a “Free, Libre and Open Source Software” (FLOSS) developing process and recurring characteristics of FLOSS projects have been discussed by various authors. But an unique FLOSS development approach does not exist. Recent research suggests patterns as a tool to describe distinctive and common features. In this paper we identify four FLOSS patterns derived f...

The population-level use of tools has been reported in various animals. Nonetheless, how tool use might spread throughout a population is still an open question. In order to answer that, we observed the behavior of inserting human hair or human-hair-like material between their teeth as if they were using dental floss in a group of long-tailed macaques (Macaca fascicularis) in Thailand. The obse...

This empirical paper shows how free/libre open source software (FLOSS) contributes to mutual and collaborative learning in an educational environment. Unlike proprietary software, FLOSS allows extensive customisation of software to support the needs of local users better. This also allows users to participate more proactively in the development and implementation process of a FLOSS-based system...
