This essay recapitulates major paths followed by the Russian tradition of what we refer to today as evolutionary developmental biology ("evo-devo"). The article addresses several questions regarding the conceptual history of evolutionary embryological thought in its particularly Russian perspective: (1) the assertion by the St. Petersburg academician Wolff regarding the possible connections bet...

Conceptual modelling has changed over years. Database applications form an integral part of most computational infrastructures. Applications are developed, changed and integrated by specialists in conceptual modelling, by computer engineers, or by people who do not have sufficient related background knowledge. Conceptual databases models are everywhere in applications and are likely to interfer...

To investigate the cortical basis of color and form concepts, we examined event-related functional magnetic resonance imaging (fMRI) responses to matched words related to abstract color and form information. Silent word reading elicited activity in left temporal and frontal cortex, where category-specific activity differences were also observed. Whereas color words preferentially activated ante...

A 36-item short-form (SF-36) was constructed to survey health status in the Medical Outcomes Study. The SF-36 was designed for use in clinical practice and research, health policy evaluations, and general population surveys. The SF-36 includes one multi-item scale that assesses eight health concepts: 1) limitations in physical activities because of health problems; 2) limitations in social acti...

In this paper, we address the problem of eliciting, communicating and validating the static data requirements of a software engineering project, while improving the end-user involvement. For this purpose, given an environment for which electronic forms are a privileged way to exchange information and stakeholders familiar with form-based (computer) interaction, we propose to use form-based user...

In the CAD/CAS field, the increasing domination of splinebased graphic objects has driven a great attention to methods focusing on the management of free-form curves. These methods range from basic manipulation of control points to more sophisticated direct manipulation techniques by using tangency or curvature constraints. However they are not suitable for the earlier conceptual stage where qu...

This study of information technology innovations makes the distinction between innovation in conceptual form and material form. The findings imply that the popularity of an IT concept responds to the broader climate of business and society and relies on the available attention in a network of related concepts.
