Although physicians are known to experience more stress than other workers, knowledge is lacking on the course of stress from a longitudinal perspective. This study explored the course of and contributors to, different dimensions of early career job-stress among physicians by means of a nationwide mail survey, with a particular emphasis on stress relating to the work-home interference. All phys...

Langmuir–Blodgett (LB) films, prepared by transferring an amphiphilic molecular monolayer (Langmuir monolayer) from a water surface onto a solid substrate, represent both archetypal and prototypical “organized films” (OFs). Known since about 80 years, LB films can be considered from many points of view as one of the prominent predecessors of what we call nanoscience today [1]. Their impact on i...

The recent EURESCO meeting on biological ageing provided an excellent overview of several trends emerging in this field of research. After many years during which the field has been dominated by controversy over the role of predetermined genetic programmes versus stochastic damage, it is now becoming clear that ageing is the result of a combination of mechanisms that are genetically modulated v...

Geometric Objects and Queries: Someone once defined a computer game as a “database with a fun interface”. Large games involve the storage and maintenance of a huge number of geometric objects, many of which change dynamically over time, and the game software needs to be able to access this information efficiently. Access to these structures takes form of queries (asking questions about the obje...

Previous studies suggest significant differences between navigating virtual environments in a life-like walking manner (i.e., using treadmills or walk-in-place techniques) and virtual navigation (i.e., flying while really standing). The latter option, which usually involves hand-centric devices (e.g., joysticks), is the most common in Virtual Reality-based studies, mostly due to low costs, less...

BACKGROUND Repair is a conservative treatment of defective composite restoration. Sealing the repair interface is a critical factor to achieve successful repaired restorations. OBJECTIVE The aim of this study was to evaluatethe effect of three finishing times on the microleakage at the composite-repair interface. METHOD Eighty composite specimens (Z250) were made and aged for eight weeks in...

People engage in small talk and conversational storytelling to provide information in engaging ways and to serve interpersonal goals such as building rapport and credibility. Embodied conversational interface agents, that represent the computer in its interaction with human users by way of a graphical humanoid body on a screen, can also profitably engage in these behaviors. We describe the ongo...

The Simple and Protected GSS-API Negotiation Mechanism defined here is a pseudo-security mechanism, represented by the object identifier iso.org.dod.internet.security.mechanism.snego (1.3.6.1.5.5.2) which enables GSS-API peers to determine in-band whether their credentials share common GSS-API security mechanism(s), and if so, to invoke normal security context establishment for a selected commo...

Spatial relations play an important role in our understanding of language. In particular, they are a crucial component in descriptions of scenes in the world. WordsEye (www.wordseye.com) is a system for automatically converting natural language text into 3D scenes representing the meaning of that text. Natural language offers an interface to scene generation that is intuitive and immediately ap...

BACKGROUND Reducing the number of tobacco outlets may help reduce smoking uptake and use; public support for such action is essential. We explored how Twitter users responded to the announcement by US pharmacy chain CVS that it was voluntarily ending tobacco sales. METHODS We used Twitter's application programming interface to retrieve tweets and retweets posted over an 8-day period in Februa...
