As a preliminary to the modern theory of measurement with which this paper is chiefly concerned, it is desirable to review a few of the characteristics and implications of classical physics to illustrate the far reaching changes that have taken place in our conception of nature as the result of the development of quantum mechanics.

the author has outlined several of the more important interpretations of measurement in quantum mechanics and discussed the problems arising from them. Particular attention was paid to the work of Bohr, Heisenberg and von Neumann and a tentative proposal was made for a possible interpretation which would mitigate some of the problems and dilemmas. This interpretation was essentially that proposed by Margenau in terms of latent variables. He defines measurement to be any operation with physical apparatus which results in a (...) number, including in this, of course, yes and no answers as well as conventional numerical answers. Further he makes the distinction between the preparation of a state and the measurement of the state. A preparation puts the quantum system into a particular state whereas the measurement frequently destroys the state in question. This paper presents several criteria to help in the evaluation of the alternatives presented in the first paper and carries further the suggested interpretation mentioned at the end of that paper.

Early utopian notions of Internet-based community as enabling transcendence of earthly governments and cultural divides manifested in the massively multiplayer online nongame platform, Second Life. However, while platform users nearly unanimously chose governance regimes based on professional management rather than democratic self-governance, one of the few democratic experiments experienced deep conflict over precisely the utopian notions it held in common. This article examines a failed merger between two experimental democratic communities in the virtual world of Second Life as an example (...) of the general failure of internet utopianism and a specific failure to transcend distinctions in cultures of origin (the “failure of convivencia,” of the title, a term reflecting a historical model chosen by one of the communities) in a common online space. Based on ethnographic fieldwork, this article will analyze a distinction between radically different, and ultimately incommensurable, discourses around governance in the merged community amid the failure of participatory, democratic models of online governance.
