The competitive bargaining set for cooperative n-person games

The continuum of solutions constituting the bargaining set for n-person games in characteristic function form (n ≥ 4) reflects various degrees of determinateness to form a coalition, different requirements of stability, or different levels of competition among the players. At one end of this continuum is the kernel solution. A new solution, called the competitive bargaining set, constitutes the other extreme. It incorporates the concept of a multiobjection, which is based on the idea that threats may be perceived and considered simultaneously even though their simultaneous implementation is impossible.For the simple homogeneous majority games [n ? 2, 1, 1, …, 1] the competitive bargaining set (1) yields unique outcomes for each coalition structure, (2) coincides with von Neumann and Morgenstern's main simple solution for certain coalition structures, and (3) converges to Shapley value as n → ∞ when the grand coalition forms.Mathematical and experimental implications of the new solution are discussed briefly.     

An analysis of speech disfluencies in down''s syndrome and in normally intelligent subjects

Spontaneous speech samples were obtained from 19 institutionalized mongoloids and from 19 normally intelligent individuals. All subjects were evaluated by a panel of speech pathologists to be nonstutterers. Subjects' speech samples were analyzed to determine (a) frequency of occurance of seven disfluency categories per 100 words spoken, (b) the proportion of each category in the total number of disfluencies. Statistically significant differences indicated that the mongoloids were more disfluent both absolutely and relatively, on categories that have been regarded as most typical to speech of stutterers. Interpretations were made to reflect on factors which may enhance the high prevalence of stuttering among Down's Syndrome patients.     

Religion and Subjective Well-Being: Western and Eastern Religious Groups Achieved Subjective Well-Being in Different Ways

Culture can moderate which variables most influence subjective well-being (SWB). Because religion can be conceptualized as culture, religious differences can be considered cultural differences. However, there have been few studies comparing how different religious groups evaluate SWB at any given time. This study is among the first to investigate this issue. The present study compared Buddhists, Taoists, Christians, and atheists. In addition to demographic items, 451 Chinese adults completed Chinese version of the Socially Oriented Cultural Conception of SWB Scale. Religious belief was distributed as follows: 10 % Christian, 20 % Buddhist, 25 % Taoist, and 43 % atheists. As predicted, the socially oriented cultural conception of SWB was found to be highest among Buddhists, followed in order by Taoists, atheists, and Christians. It was concluded that the various religious groups achieved SWB in different ways.     

Building a cognitive map by assembling multiple path integration systems

Path integration and cognitive mapping are two of the most important mechanisms for navigation. Path integration is a primitive navigation system which computes a homing vector based on an animal’s self-motion estimation, while cognitive map is an advanced spatial representation containing richer spatial information about the environment that is persistent and can be used to guide flexible navigation to multiple locations. Most theories of navigation conceptualize them as two distinctive, independent mechanisms, although the path integration system may provide useful information for the integration of cognitive maps. This paper demonstrates a fundamentally different scenario, where a cognitive map is constructed in three simple steps by assembling multiple path integrators and extending their basic features. The fact that a collection of path integration systems can be turned into a cognitive map suggests the possibility that cognitive maps may have evolved directly from the path integration system.
