Reinhart Lempp zum 60. Geburtstag
No full textMan muß im Kurschnerschen Gelehrtenkalender lange suchen, bis man auf zwei ordentliche Professoren stoßt, die sich in der Vater-Sohn-Konstellation darstellen. In der schwäbischen Familie Lempp ist das die Regel: Der Vater ist von 1929 bis 1947 ordentlicher Professor und Direktor der Staatsbauschule an der Technischen Hochschule in Stuttgart.unknownunknow
Embedding finite lattices into the \Sigma-0-2 enumeration degrees
No full textWe show that every finite lattice is embeddable into the enumeration degrees via a lattice-theoretic embedding which preserves 0 and 1
On extensions of embeddings into the enumeration degrees of the Σ02-sets
No full textWe give an algorithm for deciding whether an embedding of a finite partial order \mathcal{P} into the enumeration degrees of the \Sigma^0_2-sets can always be extended to an embedding of a finite partial order \mathcal{Q} \supset \mathcal{P}
Open problems in the enumeration degrees
No full textWe survey some open problems in the enumeration degrees. The problems fall into the following three categories: Global properties of the enumeration degrees and their local structure, the interplay between structural properties of sets and degree-theoretic properties, and the context of the enumeration degrees within the Medvedev lattice
Universal computably enumerable equivalence relations
No full textWe study computably enumerable equivalence relations (ceers), under the reducibility R ≤ S if there exists a computable function f such that x R y if and only if f(x) S f(y), for every x, y. We show that the degrees of ceers under the equivalence relation generated by ≤ form a bounded poset that is neither a lower semilattice, nor an upper semilattice, and its first-order theory is undecidable.We then study the universal ceers. We show that 1) the uniformly effectively inseparable ceers are universal, but there are
effectively inseparable ceers that are not universal; 2) a ceer R is universal if and only if R R' ≤ R, where R' denotes the halting jump operator introduced by Gao and Gerdes (answering an open question of Gao and Gerdes); and 3) both the index set of the universal ceers and the index set of the uniformly effectively inseparable ceers are Σ^0_3-complete (the former answering an open question of Gao and Gerdes)
Jumps of Sigma(0)(2)-high e-degrees and properly Sigma(0)(2) e-degrees
No full textWe show that the Sigma(2)(0) high e-degrees coincide with the high e-degrees. We also show that not every properly Sigma(2)(0) e-degree is high

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Medical students' perceptions in relation to ethnicity and gender: A qualitative study
No full textBackground
The British medical student population has undergone rapid diversification over the last decades. This study focuses on medical students' views about their experiences in relation to ethnicity and gender during their undergraduate training within the context of the hidden curriculum in one British medical school as part of a wider qualitative research project into undergraduate medical education.
Method
We interviewed 36 undergraduate medical students in one British Medical School, across all five years of training using a semi-structured interview schedule. We selected them by random and quota sampling, stratified by sex and ethnicity and used the whole medical school population as a sampling frame. Data analyses involved the identification of common themes, reported by means of illustrative quotations and simple counts.
Results
The students provided information about variations patterned by gender in their motivation and influences when deciding to study medicine. Issues in relation to ethnicity were: gaining independence from parents, perceived limitations to career prospects, incompatibility of some religious beliefs with some medical practices and acquired open-mindedness towards students and patients from different ethnic backgrounds. Despite claiming no experiences of gender difference during medical training, female and male students expressed gender stereotypes, e.g. that women bring particularly caring and sympathetic attitudes to medicine, or that surgery requires the physical strength and competitiveness stereotypically associated with men that are likely to support the continuation of gender differentiation in medical careers.
Conclusion
The key themes identified in this paper in relation to ethnicity and to gender have important implications for medical educators and for those concerned with professional development. The results suggest a need to open up aspects of these relatively covert elements of student culture to scrutiny and debate and to take an explicitly wider view of the influence of what has sometimes been called the hidden curriculum upon the training of medical professionals and the practice of medicine
