Technology and Community: Historical Complexities*

As a comment on speculations that new electronic technologies will revolutionize community, this article points to three lessons drawn from historical studies on earlier technologies such as the telephone: (1) Effects are modest; (2) effects differ from one specific technology to another; and (3) the effects of any one technology can be contradictory.     

DELIBERATELY BIASING SURVEY QUESTIONS

In “before” and “after” surveys of Attitudes Towards Random Breath Testing in South Australia, three basic versions of the questionnaire were used. In the first, a set of “lead-up” questions, which were designed to deliberately bias the results towards acceptance of the tests, was included before the main questions; in the second, there were no lead-up questions; in the third, a different set of lead-up questions was used, and was aimed at deliberately biasing the results against the tests. The results in two out of the four attempts to influence the answers (compared with no lead-up questions) were significant in the expected direction, and in the other two cases were in the correct direction but not significant. The difference between the positive-and negative-biasing versions was highly significant in both cases. It is important to be aware that changes in context rather than in question wording per se can give rise to effects which dwarf the sampling error.     

Sibling kinnections: a clinical visitation program

The growing literature on sibling relationships throughout their lifespans is of great importance to those working in the child welfare system, and in adoption services in particular. Sibling bonds are important to all of us, but they are particularly vital to children from disorganized or dysfunctional families. These relationships assume even greater importance when children from these families enter the care system. Supporting and sustaining these sibling bonds should be, and most often is, a priority throughout the child welfare system, with practice literature providing guidelines for arranging and sustaining sibling contact. However, children in the care system may also have dysfunctional sibling relationships as a result of their early experiences, and sibling visitation alone may not be enough to ensure a healthy, long-lasting relationship among siblings. Some form of sibling therapy, or 'clinically supervised visitation,' may be required to help children remove the barriers to form mutually satisfying relationships and to reinforce life-long relationships with each other.     

Simmels ‚Exkurs über die Soziologie der Sinne’ — Zentraltext einer anthropologischen Soziologie

The article reconstructs Simmel’s essay “Excursus on the Sociology of the Senses” as a central text of a sociology of the body, as a paradigmatic approach to an anthropological sociology. It re-systemizes Simmel’s partly implicit, partly explicit non-or pre-sociological aesthesiological premises on the senses as well as his twofold sociological perspective on the senses, i.e. the senses as a constituting factor of social relations on the one hand and the social regulation and construction of the senses on the other hand. Simmel’s phenomenological view on the structure and function of the senses (their immanence of abstraction, double perspective, difference and combination) is shown to be the aesthesiological foundation of his sociological approach, being perhaps part of a philosophical anthropology, that systematically reconstructs the basic significance of the senses or the body as prefiguring a person’s relation to him/herself, to the world and to others while at the same time saving him from biologistic reduction. The senses have their share in constituting the social world by which they are at the same time interpreted, modeled and constructed. Methodologically systemized in this way, Simmel’s essay in nuce reveals an aesthesiology of the senses that opens up the possibility of an anthropological sociology apt to rebalance the linguistic turn not only by an iconic turn but also by an acoustic turn (that can rediscover the sociological relevance of ‘parole’ against the dominance of ‘langue’).     

The population explosion: Where is it leading?

Over the past few centuries world demography has been characterized by both continuous absolute growth and a steadily increasing rate of growth. From 1650 or earlier to at least 1957 it was always possible to say that never has world population been so large and never has the time necessary for it to double been so short. While there are now some signs to suggest that population doubling times are stabilizing, or even increasing, the population increase in absolute numbers is nevertheless greater each year, and the rate of growth may still be faster than a simple exponential function. There can be little doubt that too large a population, together with the pressures stemming from its demands for an even higher standard of living, sets requirements greater than our planet can safely sustain. This article reviews some aspects of global population data and population dynamics.

Generalized Mann–Whitney Type Tests for Microarray Experiments

New statistical procedures are introduced to analyse typical microRNA expression data sets. For each separate microRNA expression, the null hypothesis to be tested is that there is no difference between the distributions of the expression in different groups. The test statistics are then constructed having certain type of alternatives in mind. To avoid strong (parametric) distributional assumptions, the alternatives are formulated using probabilities of different orders of pairs or triples of observations coming from different groups, and the test statistics are then constructed using corresponding several‐sample U‐statistics, natural estimates of these probabilities. Classical several‐sample rank test statistics, such as the Kruskal–Wallis and Jonckheere–Terpstra tests, are special cases in our approach. Also, as the number of variables (microRNAs) is huge, we confront a serious simultaneous testing problem. Different approaches to control the family‐wise error rate or the false discovery rate are shortly discussed, and it is shown how the Chen–Stein theorem can be used to show that family‐wise error rate can be controlled for cluster‐dependent microRNAs under weak assumptions. The theory is illustrated with an analysis of real data, a microRNA expression data set on Finnish (aggressive and non‐aggressive) prostate cancer patients and their controls.     

PORTFOLIO MODELING IN MULTIPLE-CRITERIA SITUATIONS UNDER UNCERTAINTY: COMMENT

In a recent issue of Decision Sciences, Muhlemann, Lockett, and Gear [8] developed a multiple-objective, stochastic linear programming formulation of the multiperiod portfolio selection problem under uncertainty. The purpose of this note is to offer some extensions to their multicriteria approach which is otherwise viewed as an excellent attempt at modeling realistic aspects of the portfolio selection problem. Further, integer goal programming combined with simulation is suggested as an alternate approach for solving the dynamic multiple-objective problem.
