Ida von Hahn-Hahn und Isabelle Eberhardt. Ausbruch aus Restriktionen – Auf der Suche nach sich selbst
No full textThe following thesis compares the travelogue Orientalische Briefe by the German author Ida von Hahn-Hahn with the travel journals Mes Journaliers by the French author Isabelle Eberhardt, in the context of how each woman represents herself as a female traveler and author. The comparative study analyzes whether both authors in these texts deal with the issue of breaking out of social and cultural restrictions while traveling to the ‘Orient’. The overall question of my thesis concerns what kind of filters did they use to speak about the ‘cultural other’.
The personal backgrounds of Ida von Hahn-Hahn and Isabelle Eberhardt differ in several aspects. The German author Ida von Hahn-Hahn visited the ‘Orient’ in 1843 temporarily and each place on only one occasion whereas the French author Isabelle Eberhardt constantly traveled at the end of the 19th century and at the same time she turned North Africa into her new home. These texts were analyzed in the context of gender discourse analysis, focusing on the discourse of feminity in the 19th century and the discourse of the Western world about the ‘Orient’. The comparison showed similarities and differences in the way both authors present themselves and the ‘Arab woman’ by (de-)constructing pre-existing ‘images’.
In my analysis I was able to demonstrate that both authors consciously deal with the western femininity discourse of the 19th century and the Western discourse about the ‘Orient’ by selecting similar motives. Even though their results are quite different, both authors clearly use the ‘Orient’ to express their search of one’s self
Integrable boundaries for the q-Hahn process
No full textTaking inspiration from the harmonic process with reservoirs introduced by
Giardin\`a, Kurchan and the author in arXiv:1904.01048, we propose integrable
boundary conditions for its trigonometric deformation which is known as the
q-Hahn process. Following the formalism established by Mangazeev and Lu in
arXiv:1903.00274 using the stochastic R-matrix, we argue that the proposed
boundary conditions can be derived from a transfer matrix constructed in the
framework of Sklyanin's extension of the quantum inverse scattering method and
consequently preserve the integrable structure of the model. The approach
avoids the explicit construction of the K-matrix.Comment: v1: One figure and 16 pages v2: added symmetric limit and improved

The Approximate Jordan-Hahn Decomposition
No full textNon-commutative measure theory embraces measure theory on cr-fields of subsets of a set, on projection lattices of von Neumann algebras or JBW-algebras and on hypergraphs alike [20], [27], [33], [37], [39], [40], [41]. Due to the unifying structure of an orthoalgebra concepts can easily be transferred from one branch to the other. Additional conceptual inpetus is obtained from the logico-probabilistic foundations of quantum mechanics (see [6], [19], [21]).In the late seventies the author studied the Jordan-Hahn decomposition of measures on orthomodular posets and certain graphs. These investigations revealed an interesting geometrical aspect of this decomposition in that the Jordan-Hahn property of the convex set of probability charges on a finite orthomodular poset can be characterized in terms of the extreme points of the unit ball of the Banach space dual of the base normed space of Jordan charges.</jats:p
Information seeking with Wikipedia on the iPod touch
No full textThe purpose of this paper is to present the results of a usability study which inquired into undergraduate student information seeking with Wikipedia on the iPod touch. Students characterize the overall nature of information searched for with the Wikipedia app to be for recreational and for short factual information. Recreational searching as a way in which undergraduate students utilize mobile technology is an earlier finding of Wikipedia iPod usage, and is verified as a trend of undergraduate student search using the iPod. All undergraduate student participants of the Wikipedia app on a mobile interface report this tool as helping to become more efficient in their research. Students viewed Wikipedia articles about people and concepts more so than other article types.is peer reviewedSubmitted by James Hahn ([email protected]) on 2011-02-17T02:14:29Z

Perturbations of Laguerre-Hahn functional: modification by the derivative of a Dirac delta
No full text19 pages, no figures.-- MSC2000 code: 33C47.MR#: MR2492206 (2010a:33031)Zbl#: Zbl pre05509604In this paper, we consider a perturbation of a Laguerre-Hahn functional by adding a derivative of a Dirac delta. This transformation leaves invariant the family of Laguerre-Hahn linear functionals. We shall also analyse the class of the perturbed linear functional. Finally, we illustrate these perturbations by adding the derivative of a Dirac delta to the first kind associated functional of the classical Laguerre functional. The expression of the new orthogonal polynomials is obtained.The work of the first and second author has been supported by Comunidad de Madrid-Universidad

Cichlid fishes are promising underutilized models to investigate helminth-host-microbiome interactions
No full textThe "Old Friends Hypothesis" suggests insufficient exposure to symbionts hinders immune development, contributing to increased immune-related diseases in the Global North. The microbiome is often the focus; helminths, potentially also offering health benefits, lack attention. Infection and effect of helminths are influenced and perhaps determined by microorganisms. Mechanisms behind parasite-microbiome interactions are poorly understood, despite implications on host health. These interactions are typically studied for single helminth species in laboratory animal models, overlooking helminth diversity. Reviewing research on relationships between helminth and microbial diversity yielded 27 publications; most focused on human or other mammalian hosts, relying on natural exposure rather than experimental helminth inoculation. Only about half investigated host health outcomes. Remaining knowledge gaps warrant considering additional candidate model systems. Given the high helminthiasis burden and species diversity of helminths, we propose seeking models in the Global South, where a considerable proportion of research on diversity aspects of helminth-microbiome interactions took place. Low availability of genomic resources for helminths in the Global South, however, necessitates more integrative helminthological research efforts. Given substantial similarities in immune systems, several fishes are models for human health/disease. More effort could be done to establish this for cichlids, whose representatives in the African Great Lakes provide a well-delineated, closed natural system relevant to human health in view of fish-borne zoonoses and other water-borne parasites. A good baseline exists for these cichlids' genomics, parasitology, and microbiology. We suggest exploring African Great Lake cichlids as model hosts for interactions between microbial diversity, helminth diversity, and host health.

Reescrituras de las Danzas de la Muerte en Óscar Hahn y Leopoldo María Panero
No full textThis article studies the rewriting of the medieval Dances of Death in the poems “Danza de la muerte” and “Venid a la danza mortal” by Chilean writer Óscar Hahn, and in the book of poems Danza de la muerte by Spanish author Leopoldo María Panero. The purpose of the article is to analyze which elements of the genre are preserved, what changes can be perceived and the meaning of this postmodern rewriting of medieval dances of death. Umberto Eco's thinking characterizes the context of utterance of these dances as neomedieval.En el presente artículo se estudian las reescrituras de las Danzas de la Muerte en los poemas “Danza de la muerte” y “Venid a la danza mortal” del chileno Óscar Hahn y en el poemario Danza de la muerte del español Leopoldo María Panero. El objetivo de este trabajo es analizar qué elementos del género se conservan, qué transformaciones se perciben y qué sentido tendrían estas reescrituras postmodernas de las danzas medievales de la muerte. Se caracteriza el contexto de enunciación de estas danzas como neomedieval, desde el pensamiento de Umberto Eco
An Analogy of Hahn-Banach Separation Theorem
No full textIn this paper, we introduce the notion of nearly topological linear spaces and use it to formulate an alternative definition of the Hahn–Banach separation theorem. We also give an example of a topological linear space to which the result is not valid. It is shown that R with its ordinary topology is not a nearly topological linear space.The author thanks the referee and the reviewers for their valuable comments/suggestions which improved the quality of the paper
Hahn v. Superior Court: Failing to Take the Doctrine of Strict Premises Liability to Its Logical Conclusion
No full textThis Casenote questions the holding in Hahn v. Superior Court, decided by the California Court of Appeals in 1991. In Hahn, the Court of Appeals refused to extend the doctrine of strict liability to the owner of a shopping mall based on a defective commercial establishment. The Casenote argues that the development of the doctrine of strict premises liability was arrested prematurely by the courts in California due to their effort to curb the tide of plaintiff compensation. The author argues that defective commercial establishments place the public in as much risk of harm as manufacturers of defective products. The author reasons that if the strict liability policy considerations of accident reduction and risk distribution have any meaning, they are clearly applicable to commercial licensors of defective premises, such as Hahn. She concludes that the Hahn court\u27s reluctance to so hold is another example of courts\u27 unwillingness to take the doctrine of strict premises liability to its logical conclusion
(Neodermata, Monogenea, Polystomatidae), a parasite of the Oklahoma salamander
No full textPolystomatidae is a monogenean family whose representatives infect mainly (semi)-aquatic tetrapods. Species of Sphyranura Wright, 1879 exhibit ectoparasitism on salamander hosts, with molecular work supporting their inclusion within Polystomatidae, at an early diverging, yet unresolved, position in the clade of otherwise endoparasitic polystomatid parasites of batrachian hosts. Records of representatives of Sphyranura are scarce with genetic data only available for S. oligorchis Alvey, 1933. Based on detailed morphological examination and comparison with type material, we identified worms belonging to Sphyranura infecting Oklahoma salamander (Eurycea tynerensis) as S. euryceae Hughes & Moore, 1943. Along with an amended diagnosis of Sphyranura, we provide the first molecular data for S. euryceae in the form of a mitochondrial genome and nuclear (18S, 28S rRNA) markers. Close morphological similarity between the two species of Sphyranura is reflected in low genetic divergence. Mitochondrial level comparison reveals instances of tRNA gene rearrangements in polystomatids. Although the phylogenetic reconstruction supports Sphyranura as early branching in the lineage of polystomatid monogeneans infecting batrachians, certain nodes remain unresolved
