On rank 5 projective planes
Otto Bachmann
International Journal of Mathematics and Mathematical Sciences , 1984, DOI: 10.1155/s0161171284000351
Abstract: In this paper we continue the study of projective planes which admit collineation groups of low rank (Kallaher [1] and Bachmann [2,3]). A rank 5 collineation group of a projective plane ¢ of order n ¢ ‰ 3 is proved to be flag-transitive. As in the rank 3 and rank 4 case this implies that is ¢ not desarguesian and that n is (a prime power) of the form m4 if m is odd and n=m2 with m ¢ ‰ 0mod4 if n is even. Our proof relies on the classification of all doubly transitive groups of finite degree (which follows from the classification of all finite simple groups).

Abstract: Die vorliegende Rezension besch ftigt sich mit zwei Beitr gen zu Sprache und Globalisierung aus dem Bereich der Diskursanalyse. FAIRCLOUGHs Language and Globalization analysiert eine gro e Bandbreite an Globalisierungsdiskursen. Auf theoretischer Ebene verbindet er kritische Diskursanalyse mit einer Form der politischen konomie, die die kulturellen Aspekte dieses Bereichs hervorhebt. BLOMMAERTs Einführung in die Diskursanalyse entwickelt eine ethnografische Herangehensweise mit Anleihen in der anthropologischen Linguistik und in der Soziolinguistik. In seinem Modell ist Globalisierung eine auf allen Ebenen der Analyse wirksame Kraft, die die heutigen Bedingungen von Sprachpraxis beeinflusst. Die Bücher behandeln die Thematik Sprache und Globalisierung aus unterschiedlicher Perspektive und mit verschiedenen geokulturellen Schwerpunkten. FAIRCLOUGH konzentriert sich auf die repr sentativen Eigenschaften von Sprache, die seiner Textanalyse von Globalisierungsdiskursen zugrunde liegt. BLOMMAERTs Schwerpunkt sind linguistische Repertoires und die ungleiche Gültigkeit verschiedener Sprachpraktiken unter den Bedingungen der Globalisierung. Beide Bücher haben interdisziplin res Potenzial für Lesende aus anderen Disziplinen der Sozialforschung, die sich für sprachliche Aspekte der Globalisierung interessieren. URN: urn:nbn:de:0114-fqs0801361 This review discusses two recent approaches to language and globalisation from the theoretical field of discourse analysis. FAIRCLOUGH's monograph Language and Globalization discusses a wide range of discourses of globalisation and aims to combine cultural political economy and critical discourse analysis. BLOMMAERT's book is an introduction to the study of discourse, combining an ethnographic approach influenced by American anthropological linguistics and sociolinguistics. Globalisation is integrated into his approach at all levels of analysis as shaping the conditions of language practices in society today. The books offer analyses from different thematic angles and geo-cultural perspectives: while FAIRCLOUGH focuses on the representational quality of language underlying his textual analysis of discourses of globalisation, BLOMMAERT dedicates his analysis to the shaping of linguistic repertoires and the unequal currency of language practices in a globalised world. Both offer interdisciplinary potential for readers from other disciplines of social research who are interested in language-related aspects of globalisation.

On rank 4 projective planes
O. Bachmann
International Journal of Mathematics and Mathematical Sciences , 1981, DOI: 10.1155/s0161171281000185
Abstract: Let a finite projective plane be called rank m plane if it admits a collineation group G of rank m, let it be called strong rank m plane if moreover GP=G1 for some point-line pair (P,1). It is well known that every rank 2 plane is desarguesian (Theorem of Ostrom and Wagner). It is conjectured that the only rank 3 plane is the plane of order 2. By [1] and [7] the only strong rank 3 plane is the plane of order 2. In this paper it is proved that no strong rank 4 plane exists.

Women’s struggle for emancipation through their dealings with money
Laurence Bachmann
Journal of Comparative Research in Anthropology and Sociology , 2011,
Abstract: Our study explores women’s appropriation of the democratic ideal of equality and autonomy as revealed through their handling of money within a couple relationship. We based our study on 30 in-depth interviews with partners of heterosexual couples in [country]. Our results show that women problematize themselves in terms of their autonomy and equality between the sexes through their relationship with money. They are rooting a core issue concerning their emancipation in ordinary, everyday, and apparently insignificant gestures which are often invisible to a casual onlooker. What is being witnessed, therefore, is the gendered personalisation of a social issue, with women working towards their emancipation individually rather than collectively. Gender relations are thus being reshaped, integrating two contemporary values: women’s emancipation and the emphasis on the individual.

Abstract:
Attention as a Process of Selection, Perception as a Process of Representation, and Phenomenal Experience as the Resulting Process of Perception Being Modulated by a Dedicated Consciousness Mechanism
Talis Bachmann
Frontiers in Psychology , 2011, DOI: 10.3389/fpsyg.2011.00387
Abstract: Equivalence of attention and consciousness is disputed and necessity of attentional effects for conscious experience has become questioned. However, the conceptual landscape and interpretations of empirical evidence as related to this issue have remained controversial. Here I present some conceptual distinctions and research strategies potentially useful for moving forward when tackling this issue. Specifically, it is argued that we should carefully differentiate between pre-conscious processes and the processes resulting in phenomenal experience, move the emphasis from studying the effects of attention on the modality-specific and feature-specific perception to studying attentional effects on panmodal universal attributes of whatever conscious experience may be the case, and acknowledge that there is a specialized mechanism for leading to conscious experience of the pre-consciously represented contents autonomous from the mechanisms of perception, attention, memory, and cognitive control.
Monte Carlo Simulations
Michael Bachmann
Physics , 2011,
Abstract: Monte Carlo computer simulations are virtually the only way to analyze the thermodynamic behavior of a system in a precise way. However, the various existing methods exhibit extreme differences in their efficiency, depending on model details and relevant questions. The original standard method, Metropolis Monte Carlo, which provides only reliable statistical information at a given (not too low) temperature has meanwhile been replaced by more sophisticated methods which are typically far more efficient (the differences in time scales can be compared with the age of the universe). However, none of the methods yields automatically accurate results, i.e., a system-specific adaptation and control is always needed. Thus, as in any good experiment, the most important part of the data analysis is statistical error estimation.
Effective Classical Hamiltonian from Perturbatively Defined Path Integral
Michael Bachmann
Physics , 2011,
Abstract: Introducing a perturbative definition, phase space path integrals can be calculated without slicing. This leads to a short-time expansion of the quantum-mechanical path amplitude, or a high-temperature expansion of the unnormalized density matrix, respectively. We use the proposed formalism to calculate the effective classical Hamiltonian for the harmonic oscillator.
