The “Three Waves” of Industrial Group Work: Historical Reflections on Current Research on Group Work

This paper deals with the three waves of the discourse on group work in social science and industrial practice that have helped pave the way for the current boom in the introduction of group work in companies. These waves are represented by the human relations approach, the sociotechnical systems approach, and the lean management debate. They are reviewed in two perspectives. The first relates to their concepts of work design and group work, following four questions: (a) What emphasis is put on work factors or on subjective orientations, on the design of working conditions or symbolic strategies? (b) How do the various approaches address the relationship between efficiency and control? (c) Which concepts of participation or democracy are involved? (d) How is the role of the social scientist in the process of industrial modernization conceptualized, explicitly or implicitly? The second perspective from a sociology of science relates to the context of production and utilization of social scientific knowledge. In general, two theses are put forward. The first states that a gap exists between the aspirations and reality of group work because the basic conflict of efficiency and control has been overlooked for ideological reasons. The second postulates that there is no linear progress in the theory and practice of group work. It seems that the socioeconomical context determines reasonably which group concept and ideology dominates certain historical phases of industrial modernization.     

Two-stage discrete aggregation: the Ostrogorski paradox and related phenomena

Motivated by certain paradoxa that have been discussed in the literature (Ostrogorski paradox), we prove an impossibility theorem for two-stage aggregation procedures for discrete data. We consider aggregation procedures of the following form: The whole population is partitioned into subgroups. First we aggregate over each subgroup, and in a second step we aggregate the subgroup aggregates to obtain a total aggregate. The data are either dichotomous (1 — 0; yes-no) or take values in a finite ordered set of possible attributes (e.g., exam grades A, B,...F). Examples are given by multistage voting procedures (indirect democracy, federalism), or by the forming of partial grades and overall grades in academic examinations and similar evaluation problems (sports competitions, consumer reports). It is well known from standard examples that the result of such a two-stage aggregation procedure depends, in general, not only on the distribution of attributes in the whole population, but also on how the attributes are distributed across the various subgroups (in other words: how the subgroups are defined). This dependence leads to certain paradoxa. The main result of the present paper is that these paradoxa are not due to the special aggregation rules employed in the examples, but are unavoidable in principle, provided the aggregators satisfy certain natural assumptions. More precisely: the only aggregator functions for which the result of a two-stage (a fortiori: multi-stage) aggregation does not depend on the partitioning are degenerate aggregators of the following form: there exists a partial order (dominance) on the set of possible attributes such that the aggregate over any collection of data is always equal to the supremum (w.r.t. dominance) of the attributes occurring in the data, regardless of the relative frequnencies of these occurrences. In the voting context, degeneracy corresponds to the unanimity principle. Our theorem is true for arbitrary partitionings of arbitrary (finite) sets and generalizes the results of Deb & Kelsey (for the matrix case with dichotomous variables and majority voting) to general two-stage aggregation procedures for attributes belonging to a finite ordered set. The general result is illustrated by some examples.This paper was completed during a visit to the University of Bielefeld. I am much indebted to the Faculty of Economics there for its hospitality; in particular I should like to thank Gerhard Schwödiauer and Walter Trockel for their support.     

Measures of Societal Risk and Their Potential Use in Civil Aviation

This article seeks to clarify the conceptual foundations of measures of societal risk, to investigate how such measures may be used validly in commonly encountered policy contexts, and to explore the application of these measures in the field of civil aviation. The article begins by examining standard measures of societal and individual risk (SR and IR), with attention given to ethical as well as analytical considerations. A comprehensive technical analysis of SR is provided, encompassing scalar risk measures, barrier functions, and a utility‐based formulation, and clarifications are offered with respect to the treatment of SR in recent publications. The policy context for SR measures is shown to be critically important, and an extension to a hierarchical setting is developed. The prospects for applying SR to civil aviation are then considered, and some technical and conceptual issues are identified. SR appears to be a useful analytical tool in this context, provided that careful attention is given to these issues.     

Axiomatizations of public good indices with a priori unions

We provide axiomatizations for six variants of the Public Good Index (PGI) for games with a priori unions. Two such coalitional PGIs have been introduced and alternatively axiomatized in Alonso-Meijide et al. (Working paper 18, 2008b). They assign power in two steps. In the first step, power is distributed between unions according to the PGI of the quotient game. In a second step, the Solidarity PGI splits power equally among union members while the Owen Extended PGI takes into account so-called essential parts. The other four coalitional PGIs have been introduced in Holler and Nohn (Homo Oeconomicus 26, 2009). The first variant elaborates the original idea of Holler (Political Studies 30:262–271, 1982) that the coalitional value is a public good and only minimal winning coalitions of the quotient game are relevant. The remaining three variants also use the two-step distribution where, however, on the member stage they take into account the possibilities of players to threaten their partners through leaving their union.     

Messung der Qualität in Dienstleistungscentern – am Beispiel eines Flughafens

The study shows that customers’ perception of overall quality in services centers is driven by two components: the service encounter quality and the quality of the servicecape. Thus, customers’ overall evaluation of service quality in a services center is a function of n service encounter qualities (k?=?1…n) and the quality of the servicecape. Furthermore, it is of great importance for the quality management of a services center that there could be (1) direct effects between the quality dimensions and the overall service quality as well as (2) direct effects between the quality dimensions themselves. The above mentioned study had been carried out exemplarily at the EuroAirport Basel-Mulhouse-Freiburg. The survey results suggest that servicecape quality has a significant effect both on the overall service quality and on the service encounter qualities. Moreover, the study shows that key quality indicators of the service center apply to the perception of security as well as to the service environment (for instance, arrangement of check-in/security desk, comfort of seats, ambience of waiting area).     

Resource use overlap between urban carnivores: Implications for endangered San Joaquin kit foxes (<Emphasis Type="Italic">Vulpes macrotis mutica</Emphasis>)

An urban population of Endangered San Joaquin kit foxes (Vulpes macrotis mutica) has persisted in the city of Bakersfield, (Kern County, California), for several decades. Urban kit foxes may play an important role in future range wide recovery efforts for the species. As such, a comprehensive understanding of the issues that can influence the long-term survival of this population is essential for the development of effective management strategies. Although urban kit foxes have been studied extensively in Bakersfield, interactions between kit foxes and other urban carnivore species are poorly understood. Urban environments can provide a number of opportunities for species to interact in ways not usually observed in natural habitats. Interactions between urban populations of striped skunks (Mephitis mephitis) and kit foxes were investigated at denning locations and cat feeding stations on the California State University-Bakersfield campus, California, USA. A total of 130 individual denning sites were identified, of which 39 (30%) were used by both species. Simultaneous den use by foxes and skunks was recorded on four occasions. Inter and intra-specific aggression was recorded at cat feeding stations on ten separate occasions including three incidences of aggression towards kit foxes by skunks and feral cats (Felis catus). Telemetry data and cat feeding station observations clearly show that interspecific contact does occur in urban environments.     

Hochschulentwicklung und Bürgerrechte in der BRD und der DDR

The universities in the Federal Republic of Germany are expanding more or less continuously since the 1950s; the expansion of those in the German Democratic Republic, by contrast, stagnated since 1971. The two patterns of educational development are due to different normative concepts of the social order. Educational policy in socialist East Germany gave institutional expression to the belief in objective laws of social development and hence in an objective demand for highly qualified manpower. In this normative context higher education took on a particular meaning and functions, provoked serious social conflicts and was finally reduced by political decree. In the Federal Republic, by contrast, freedom of educational and occupational choice prevailed, and the former elitist academic education was popularized. At the same time the culture of professionalism expanded in the world of work. In this process higher education turned into a matter of universal social interest.
