Sister chromatid cohesion is required for proper chromosome segregation during cell division. One group of proteins that is essential for sister chromatid cohesion during mitosis and meiosis is the RAD21/REC8 family of cohesin proteins. Two cohesin proteins are found in yeast; one that functions mainly in mitosis while the other participates in meiosis. In contrast, only one cohesin gene appear...

Web 2.0 sociable technologies (such as social network sites, SNS) create new online interpersonal collaboration and communication. Particularly, given the proliferation of virtual community page (VCP, ex. Facebook fan page and group) participation, the sustainability of VCP has been recognized as a critical issue. While existing studies have started to address this issue through classical indiv...

Text cohesion is an important element of discourse processing. This paper presents a new approach to modeling, quantifying, and visualizing text cohesion using automated cohesion flow indices that capture semantic links among paragraphs. Cohesion flow is calculated by applying Cohesion Network Analysis, a combination of semantic distances, Latent Semantic Analysis, and Latent Dirichlet Allocati...

Zebrafish has been a favourite of developmental biologists and numerous genetic tools have been developed for this species. In recent years, zebrafish has become an increasingly popular subject of neuroscientists and behavioural scientists. One of the typical characteristics of zebrafish is shoaling, individuals forming a tight group in which fish swim together. The biological mechanisms of soc...

Globalization has seen the emergence of virtual teams solving complex organisational problems using computer-mediated technologies. By extending Media Richness Theory, it was the aim of this research to demonstrate that virtual teams can utilise a lean medium, such as email, for effectively solving an equivocal problem, given that participants develop a shared-social construction. A quantitativ...

Different approaches examine discourse markers: descriptive and formal approaches (quantitative or qualitative, synchronic or diachronic) connectives and discourse markers. This article presents a study case of discourse markers used in unacceptable way from a grammatical and cohesion point of view in a learning environment. Two questions will be discussed: Are these type of use produce reading...
