Joint action and group action made precise

The paper argues that there are two main kinds of joint action, direct joint bringing about (or performing) something (expressed in terms of a DO-operator) and jointly seeing to it that something is the case (expressed in terms of a Stit-operator). The former kind of joint action contains conjunctive, disjunctive and sequential action and its central subkinds. While joint seeing to it that something is the case is argued to be necessarily intentional, direct joint performance can also be nonintentional. Actions performed by social groups are analyzed in terms of the notions of joint action (basically DO and Stit).A precise semantical analysis of the aforementioned kinds of joint action is given in terms of time-trees. With each participant a tree is connected, and the trees are joined defining joint possible worlds in terms of state-expressing nodes from the trees. Sentences containing DO and Stit are semantically evaluated with respect to such joint possible worlds. Intentional joint actions are characterized in terms of the notion of we-intention (joint intention), characterized formally by means of a special operator.     

MISCONCEPTIONS OF THE SOCIAL SCIENCES

Abstract. Scholars in religious studies, or "religionists," often mischaracterize the social-scientific study of religion. They assume that a social-scientific analysis of the origin, function, meaning, or truth of religion either opposes or disregards the believer's analysis, which religionists profess to present and defend. I do not argue that the social sciences analyze religion from the believer's point of view. I argue instead that a social scientific analysis is more akin and germane to the believer's point of view than religionists assume. I single out seven mischaracterizations of the social sciences typically held by religionists.     

Social interaction and the development of cognitive operations

This paper presents two experiments to support the general hypothesis that the coordination of actions between individuals promotes the acquisition of cognitive coordinations. The first experiment shows that two children, working together, can successfully perform a task involving spatial coordinations; children of the same age, working alone, are not capable of performing the task. The second experiment shows that subjects who did not possess certain cognitive operations involved in Piaget's conservation of liquids task acquire these operations after having actualized them in a social coordination task.     

Walden two: The morality of anarchy

The utopian label is often pinned on calls for comprehensive change as a means of dismissing them from serious consideration.... [S]ocial orders come and go, and those who indulge in utopian thinking may be more prepared for... the inevitability of widespread societal transformation.... Keeping utopia in mind can prevent our settling for minor reforms when more significant change might be possible. (Fox, 1985, p. 55)When... I called myself a benign anarchist... someone said that that was not like the dictatorship of Walden Two. But Walden Two was anarchistic.... The functions delegated to [authority figures] in the world at large were performed by the people themselves through face-to-face commendation and censure. (Skinner, 1983, p. 426, emphasis his)The issue for anarchists is not whether there should be structure or order, but what kind there should be and what its sources ought to be. The individual or group which has sufficient liberty to be self-regulating will have the highest degree of order; the imposition of order from above and outside induces resentment and rebellion where it does not encourage childlike dependence and impotence, and so becomes a force for disorder. (Barclay, 1982, p. 17).     

Instrumentation for an electrocutaneous communication device

The device described is a prototype that uses spatiotemporal resolution for electrocutaneous stimulation. Signals initiated through a keyboard activate a matrix of four electrodes that may be applied to the fingers, forearm, abdomen, back, or other parts of the integument. The instrumentation described includes a pulse generator, the active time and delay time controls, the control of the total length of a pulse train, and the constant-current generators whose output is fed into the electrodes. This device may be used as an interface with an alphanumeric device (e.g., a calculator or computer) and as a basic instrument in research investigating the spatial and temporal resolving capacities of the skin senses.
