INFORMATION TECHNOLOGY AND THE CHARACTER OF CONTEMPORARY LIFE

The paper deals with the basic features of the life-space created by contemporary information industry,and with the dominant attitudes towards the opportunities and limitations information technology offers and imposes. We consider the problem of information glut, the quality of public discourse, the question of privacy and technological alienation. Concerning the basic attitudes, we discuss the aesthetic, the moral and the religious views, considered in the context of the present life-space pervaded and shaped by information technology. The paper concludes with a discussion of the possible consequences of global homogenization and of the cultural ahistoricity that are being created by the massive use of information technology. Among the positive aspects of this new 'global culture of the present' we point out the possible increase of global human solidarity; among the negative ones, we point out the flattening and shrinking of the space of human experience, which this uniform culture of the present imposes.     

Organizations,coalitions, and movements

This article uses empirical evidence on networks of voluntary organizations mobilizing on ethnic minority, environmental, and social exclusion issues in two British cities, to differentiate between social movement processes and other, cognate collective action dynamics. Social movement processes are identified as the building and reproducing of dense informal networks between a multiplicity of actors, sharing a collective identity, and engaged in social and/or political conflict. They are contrasted to coalitional processes, where alliances to achieve specific goals are not backed by significant identity links, and organizational processes, where collective action takes place mostly in reference to specific organizations rather than broader, looser networks.     

HITTING LINES and CIRCLES WITH DIFFUSION PROCESSES

For (x(t),y(t)), a diffusion process starting from (x(0),y(0)) = (x,y), the problem of computing the moment generating function of the first passage time T(x, y) to a given subset D of IR²is considered. A particular case of the method of similarity solutions is used. The problems that can be solved explicitly are those for which D is either a straight line or a circle.     

The 1970 US draft lottery revisited: a spatial analysis

Summary.  We revise the result of the 1970 selective service draft lottery in the USA following an open question that was suggested by Fienberg in a paper published in Science in 1971. The result of the drawings can be viewed as a particular spatial pattern which can be analysed by using general spatial tools adapted to our context. Approaches for assessing the complete spatial randomness for this spatial process on a finite support are proposed. More specifically, these approaches involve the number of events in a square window and a k ( r )-based function used to analyse stationary spatial point processes.     

NONPARAMETRIC STATISTICS IN MULTICRITERIA ANALYSIS

The paper deals with a method of hierarchization of alternatives in a multicriteria environment by means of statistical nonparametric procedures. For each criterion, alternatives are disposed on an ordinal scale. After that a procedure similar to ANOVA is activated on the data. The differences relating to the average ranks of each action are used to build the hierarchical algorithm. The concept of outranking, in a probabilistic meaning, is reached in this way. Thereafter, we arrive at the concept of dominance using pairwise comparisons. A case study is presented which implements the methodological suggestion.     

Fuzzy multi-attribute decision-making for grouping of electronic components in process planning

The grouping of objects problem has a wide-range of applications in industry. In electronic assembly planning, grouping components play an important role as they can reduce drastically the number of possible sequences of operations. This paper considers the grouping problem of electronic component families based on their multiple attributes. The difficulty lies with the conflict of criteria when selecting a certain component into a group. In order to overcome this difficulty, the proposed approach introduces the concept of fuzziness, which expresses the degree of concordance on the decision. An example of classification electronic components is presented to illustrate the proposed method.
