The study of measurable and integrable selections from a correspondence (set-valued function) has been of interest for some time [e.g., see Aumann (1965), Hildenbrand (1974), etc.]. Here we take up the study of distributions of such selections. The motivation for doing this comes from Mathematical Economics [see Kannai (1970, section 7); the reader interested in the economic applications is ref...

A major concern in psychology and education is that rewards decrease intrinsic motivation to perform activities. Over the past 30 years, more than 100 experimental studies have been conducted on this topic. In 1994, Cameron and Pierce conducted a meta-analysis of this literature and concluded that negative effects of reward were limited and could be easily prevented in applied settings. A more ...

In this study, we investigated whether adopting a head-centered perspective on the body is an embodied process by means of the graphesthesia task. This task consists of interpreting ambiguous tactile symbols from different spatial perspectives. The results revealed that symbols were more easily recognized when the mental rotation of the head toward the stimulated surface corresponded to physica...

Suicide attempts and completions by individuals while naked remain unexplored, both by clinicians and in the professional literature. Nakedness at the time of the incident conveys important information about an individual's mental state. Motivations for attempting or completing suicide while naked are discussed. Nakedness during a suicide attempt is presumptive evidence of high risk for suicide...

This study aimed to explore the relationships between foreign language learners’ self-identity changes, motivation types, and Foreign Language proficiency associated with learning English in private language schools in Iranian context. Based on a stratified sampling, 204 English as a foreign language learners from three language schools in Tehran were selected to participate in the study. The i...

In this paper, we introduce the ghost-box-ball system, which is an extended version of classical soliton cellular automaton. It initially motivated as a mechanism for making precise connection between Schensted insertion (of Robinson-Schensted-Knuth correspondence) and dynamical process box-ball system. addition to motivation, explore generalisations notions including solitonic phenomenon, asym...
