Few studies have examined whether factors predicting obligatory exercise differ by gender. 303 participants completed the Obligatory Exercise Questionnaire and the Reason for Exercise Inventory. All variables correlated significantly. However, the correlation between exercising for fitness and obligatory exercise was significantly stronger in women than men. In women, obligatory exercise was pr...

In this project a mobile autonomous robot is developed that navigates and fulllls transportation tasks in dynamically changing industrial environments. Three obligatory ingredients are a goal-directed robot control architecture, a position-estimation mechanism for navigation purposes, and a wireless communication link to other robots and a control center.

Protein-protein interfaces have been evolutionarily-designed to enable transduction between the interacting proteins. Thus, we hypothesize that analysis of the dynamics of the complex can reveal details about the nature of the interaction, and in particular whether it is obligatory, i.e., persists throughout the entire lifetime of the proteins, or not. Indeed, normal mode analysis, using the Ga...

This is the second part of a two-part article that reviews a number of the current debates regarding raising and control constructions. The issues addressed in this part include the spectrum of related raising (e.g. possessor raising, further raising) and control (partial, split, generic, super-equi) phenomena; cross-linguistic typology, including backward and copy constructions; and their acqu...

This paper raises the empirical point that modal subordination is not always obligatory, and that moreover, this is a point of lexical variation. Some modals, like will, which I call definite modals, undergo modal subordination obligatorily, and some, like gonna, which I call nondefinite modals, do so optionally. I propose a dynamic framework in which, following from Frank (1997), information s...
