Generalized vortex-model for the inverse cascade of two-dimensional turbulence
Jan Friedrich,Rudolf Friedrich
Physics , 2011, DOI: 10.1103/PhysRevE.88.053017
Abstract: We generalize Kirchhoff's point vortex model of two-dimensional fluid motion to a rotor model which exhibits an inverse cascade by the formation of rotor clusters. A rotor is composed of two vortices with like-signed circulations glued together by an overdamped spring. The model is motivated by a treatment of the vorticity equation representing the vorticity field as a superposition of vortices with elliptic Gaussian shapes of variable widths, augmented by a suitable forcing mechanism. The rotor model opens up the way to discuss the energy transport in the inverse cascade on the basis of dynamical systems theory.
Anti-Robinson Structures for Analyzing Three-Way Two-Mode Proximity Data  [PDF]
Hans-Friedrich K?hn
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.56094
Abstract:

Multiple discrete (non-spatial) and continuous (spatial) structures can be fitted to a proximity matrix to increase the information extracted about the relations among the row and column objects vis-à-vis a representation featuring only a single structure. However, using multiple discrete and continuous structures often leads to ambiguous results that make it difficult to determine the most faithful representation of the proximity matrix in question. We propose to resolve this dilemma by using a nonmetric analogue of spectral matrix decomposition, namely, the decomposition of the proximity matrix into a sum of equally-sized matrices, restricted only to display an order-constrained patterning, the anti-Robinson (AR) form. Each AR matrix captures a unique amount of the total variability of the original data. As our ultimate goal, we seek to extract a small number of matrices in AR form such that their sum allows for a parsimonious, but faithful reconstruction of the total variability among the original proximity entries. Subsequently, the AR matrices are treated as separate proximity matrices. Their specific patterning lends them immediately to the representation by a single (discrete non-spatial) ultrametric cluster dendrogram and a single (continuous spatial) unidimensional scale. Because both models refer to the same data base and involve the same number of parameters, estimated through least-squares, a direct comparison of their differential fit is legitimate. Thus, one can readily determine whether the amount of variability associated which each AR matrix is most faithfully represented by a discrete or a continuous structure, and which model provides in sum the most appropriate representation of the original proximity matrix. We propose an extension of the order-constrained anti-Robinson decomposition of square-symmetric proximity matrices to the analysis of individual differences of three-way data, with the third way representing individual data sources. An application to judgments of schematic face stimuli illustrates the method.

Becoming “Member Enough”: The Experience of Feelings of Competence and Incompetence in the Process of Becoming a Professor
Thomas Friedrich
Indo-Pacific Journal of Phenomenology , 2010,
Abstract: The graduate teaching assistant prepares to enter a classroom for the first time as its instructor beset by feelings of incompetence: indeed, learning to successfully display a professional identity is often a terrifying experience, such that promising novices may abandon it prematurely. This hermeneutic phenomenological study asks one female doctoral candidate the following question: What is the experience of feelings of competence and incompetence in the process of becoming a professor? The core finding of this interview-based study is the thematic demarcation of sequential stages in the participant’s experience of the process of becoming “member enough”. In the presentation of the findings, the identification of the central themes is validated with excerpts from the interview data, and their implications for the study of competence, the sociocultural study of identity development, and the mentoring of pre-service college faculty discussed.

Library planning in Germany
Friedrich Geisselmann
Liber Quarterly : The Journal of European Research Libraries , 2003,
Abstract: The position and the efficiency of German libraries are rather ambivalent. On the one hand the infrastructure is quite well developed: 2000 public library systems with full time personnel, 275 million books issued, 75 million Euro for acquisitions; 280 scientific general libraries, 60 million books issued, 1300 million Euro for acquisitions. Nevertheless there are a lot of problems, which arise from the administrative structure and the political position of libraries.

The Shadow Economy in Germany - A Blessing or a Curse for the Official Economy?
Schneider, Friedrich
Economic Analysis and Policy , 2008,
Abstract: This article provides an estimation of the size and development of the shadow economy of Germany, using various estimation procedures. The shadow economy is defined as market-bound production of goods and services which escape detection in the official estimates of GDP. An increased burden of taxation and social security payments, combined with intensive labour market regulation, insufficient quality of state institutions and low tax morale are the driving forces for the shadow economy. Moreover, the results of recent surveys for Germany demonstrate that the readiness to undertake illicit employment as well as its acceptance is high in Germany and other countries. Finally, conclusions are made about the effect of the shadow economy on the official one and incentive-oriented policy means are presented, so that the ‘black’ value added can be transformed into the official value added.

Uniform distribution of sequences connected with the weighted sum-of-digits function
Friedrich Pillichshammer
Uniform Distribution Theory , 2007,
Abstract: In this paper we consider sequences which are connected with the so-called weighted $q$-ary sum-of-digits function and give an {\it if and only if} condition under which such sequences are uniformly distributed modulo one. The sequences considered here contain the $q$-ary van der Corput sequence as well as the $(n\alpha)$-sequences as special cases.
