Evolution of Knowledge Bases (KBs) consists of incorporating new information in an existing KB. Previous studies assume that the new information should be fully trusted and thus completely incorporated in the old knowledge. We suggest a setting where the new knowledge can be partially trusted and develop model-based approaches (MBAs) to KB evolution that rely on this assumption. Under MBAs the ...

A measure of men's attitudes toward their body (MBAS) was developed and evaluated via three independent samples of college men. In Studies 1 and 2, factor analyses determined and cross-validated the MBAS's underlying structure. Three factors emerged from the items: muscularity, low body fat, and height. Studies 1 and 2 provided construct (i.e., convergent, concurrent, and discriminant) validity...

This paper describes recent levels of surfactants measured in a coastal lagoon ecosystem highly stressed by human activites: the Orbetello lagoon (Southern Tuscany, Italy, Ramsar Site IT008). Significance of difference among concentrations measured before and after summertime are explored in order to evaluate effects related to tourism exploitation. Among surfactants, methylene blue active anio...

In this article, we tested the vulnerability hypothesis of the behavioral approach system (BAS) hypersensitivity model of bipolar disorders. We examined whether selfreported BAS sensitivity predicts lifetime bipolar spectrum diagnoses as well as symptoms and personality characteristics associated with bipolar disorder using a retrospective and concurrent behavioral high-risk design. Participant...

Anionic surfactants are commonly determined with the use of the methylene blue active substances (MBAS) standard method, which is time-consuming and labor-intensive. Therefore, new methods for determination of anionic surfactants are needed. In this study, the standard MBAS method for determination of anionic surfactants was modified and adjusted to work in a continuous flow system combined wit...

This chapter introduces the concept of multi-beam antenna (MBA) in mobile ad hoc networks and the recent advances in the research relevant to this topic. MBAs have been proposed to achieve concurrent communications with multiple neighboring nodes while they inherit the advantages of directional antennas, such as the high directivity and antenna gain. MBAs can be implemented in the forms of mult...

In this paper, several parameterlslate estimation approaches for the determination ofdragpolars from flight data are described and evaluated for a fly-by-wire (FBW) aircraft. Bolh model-based approaches (MBAs) and non-model-based approaches (NMBAs) are considered. Dynamic.response data from roller coaster and windupturn manoeuvres are generated in a FBW aircraft flight simulator at different fl...

Several studies have demonstrated that men express body dissatisfaction differently than women. Although specific instruments that address body dissatisfaction in men have been developed, only a few have been validated in Latin-American male populations. The aim of this study was to reassess the factor structure of the Spanish versions of the Drive for Muscularity Scale (DMS-S) and the Male Bod...

This paper assesses the relative importance of various explanations for the gender gap in career outcomes for highly-educated workers in the U.S. corporate and financial sectors. The careers of MBAs, who graduated between 1990 and 2006 from a top U.S. business school, are studied to understand how career dynamics differ by gender. Although male and female MBAs have nearly identical (labor) inco...

Recent works have shown that the thermal inertia of km-sized near-Earth asteroids (NEAs) is more than two orders of magnitude higher than that of main belt asteroids (MBAs) with sizes (diameters) between 200 and 1,000 km. This confirms the idea that large MBAs, over hundreds millions of years, have developed a fine and thick thermally insulating regolith layer, responsible for the low values of...
