Lichtheimia Species Exhibit Differences in Virulence Potential
Volker U. Schwartze, Kerstin Hoffmann, Ildikó Nyilasi, Tamás Papp, Csaba Vágv?lgyi, Sybren de Hoog, Kerstin Voigt, Ilse D. Jacobsen
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0040908
Abstract: Although the number of mucormycosis cases has increased during the last decades, little is known about the pathogenic potential of most mucoralean fungi. Lichtheimia species represent the second and third most common cause of mucormycosis in Europe and worldwide, respectively. To date only three of the five species of the genus have been found to be involved in mucormycosis, namely L. corymbifera, L. ramosa and L. ornata. However, it is not clear whether the clinical situation reflects differences in virulence between the species of Lichtheimia or whether other factors are responsible. In this study the virulence of 46 strains of all five species of Lichtheimia was investigated in chicken embryos. Additionally, strains of the closest-related genus Dichotomocladium were tested. Full virulence was restricted to the clinically relevant species while all strains of L. hyalospora, L. sphaerocystis and Dichotomocladium species were attenuated. Although virulence differences were present in the clinically relevant species, no connection between origin (environmental vs clinical) or phylogenetic position within the species was observed. Physiological studies revealed no clear connection of stress resistance and carbon source utilization with the virulence of the strains. Slower growth at 37°C might explain low virulence of L. hyalospora, L. spaherocystis and Dichotomocladium; however, similarly slow growing strains of L. ornata were fully virulent. Thus, additional factors or a complex interplay of factors determines the virulence of strains. Our data suggest that the clinical situation in fact reflects different virulence potentials in the Lichtheimiaceae.
Data Partitions, Bayesian Analysis and Phylogeny of the Zygomycetous Fungal Family Mortierellaceae, Inferred from Nuclear Ribosomal DNA Sequences
Tamás Petkovits, László G. Nagy, Kerstin Hoffmann, Lysett Wagner, Ildikó Nyilasi, Thasso Griebel, Domenica Schnabelrauch, Heiko Vogel, Kerstin Voigt, Csaba Vágv?lgyi, Tamás Papp
PLOS ONE , 2011, DOI: 10.1371/journal.pone.0027507
Abstract: Although the fungal order Mortierellales constitutes one of the largest classical groups of Zygomycota, its phylogeny is poorly understood and no modern taxonomic revision is currently available. In the present study, 90 type and reference strains were used to infer a comprehensive phylogeny of Mortierellales from the sequence data of the complete ITS region and the LSU and SSU genes with a special attention to the monophyly of the genus Mortierella. Out of 15 alternative partitioning strategies compared on the basis of Bayes factors, the one with the highest number of partitions was found optimal (with mixture models yielding the best likelihood and tree length values), implying a higher complexity of evolutionary patterns in the ribosomal genes than generally recognized. Modeling the ITS1, 5.8S, and ITS2, loci separately improved model fit significantly as compared to treating all as one and the same partition. Further, within-partition mixture models suggests that not only the SSU, LSU and ITS regions evolve under qualitatively and/or quantitatively different constraints, but that significant heterogeneity can be found within these loci also. The phylogenetic analysis indicated that the genus Mortierella is paraphyletic with respect to the genera Dissophora, Gamsiella and Lobosporangium and the resulting phylogeny contradict previous, morphology-based sectional classification of Mortierella. Based on tree structure and phenotypic traits, we recognize 12 major clades, for which we attempt to summarize phenotypic similarities. M. longicollis is closely related to the outgroup taxon Rhizopus oryzae, suggesting that it belongs to the Mucorales. Our results demonstrate that traits used in previous classifications of the Mortierellales are highly homoplastic and that the Mortierellales is in a need of a reclassification, where new, phylogenetically informative phenotypic traits should be identified, with molecular phylogenies playing a decisive role.
Active and Healthy Ageing at Work—A Qualitative Study with Employees 55 - 63 Years and Their Managers  [PDF]

Abstract: The proportion of elderly individuals in the population is increasing in most industrial countries. This demographic change increases the need of more people who work until an older age to maintain the welfare in the states. However, it is not clear if older employees are interested to in generally extend the working life to an older age. It is also not stated if managers in organizations are interested of extending their older employees working life. The overall aim of this study was to examine older employees own experience of their work situation and ageing at work. The aim was also to investigate their managers’ attitude to them as older employees. The investigation was conducted by focusing group interviews with employees aged 55 - 63 years, and with their mangers aged 40 - 63 years. The findings stated that the older employees’ consideration for an extend working life seemed to be based on their health and health problems in relation to their work situation; their personal economy; their managers attitude to them as elderly and the possibility to social inclusion at work; and their possibilities for self-crediting activities at work despite their age. The managers seem to have a positive attitude to some of the older employees’ experience knowledge, if that was in the same direction as their own interest. Otherwise the mangers saw the older employees as problem and obsoleted. The managers were also negative to older employees who got health problems which effect the work production negatively. The older workers in this study described managers’ importance to if they want to work in an extended working life. However, the managers seem not to understand their own importance in this and were not interested to keep all elderly in an extended working life.
The Influence of Work Environmental and Motivation Factors on Seniors’ Attitudes to an Extended Working Life or to Retire. A Cross Sectional Study with Employees 55 - 74 Years of Age  [PDF]
Kerstin Nilsson
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.57003
Abstract: Aim: The aim of this study was to investigate difference between whether individuals think they can work, and want to work until 65 years or not. Methods: A cross/sectional study including survey of 1949 employees aged 55 - 74 years. Results: Working environments were the most significant differences between the groups associated to if the respondents think they can work beyond 65 years or not. Motivation factors were the most significant differences between the groups associated with if the respondents want to work beyond 65 years or not. Conclusions: A satisfying work environment is important to whether people think they can work or not. Nevertheless, whether people want to work is depending on whether the employees are satisfied with the factors that promote their motivation for work. If society wants more people to work until an upper age, it is important to improve both work environmental factors and motivation factors in their work situation.
Naufrágio, cativeiro, e rela??es ibéricas: a História trágico-marítima num contexto comparativo
Voigt, Lisa;
Varia Historia , 2008, DOI: 10.1590/S0104-87752008000100010
Abstract: this essay compares sixteenth - and early seventeenth-century portuguese shipwreck narratives, many of which were collected and published in bernardo gomes de brito's história trágico-marítima (1735-1736), with early modern spanish accounts of shipwreck and captivity. by examining not only the common strategies and structures of shipwreck and captivity narratives, but also direct intertextual connections, it illuminates the shared literary and ideological context of the early modern iberian empires. the comparison highlights the pleasurable as well as the didactic dimensions of these narratives for early modern writers and readers, thus challenging both nationalist interpretations and those that focus exclusively on their counter-hegemonic potential.

De-Ritualisierung De-Ritualization
Anna Voigt
querelles-net , 2007,
Abstract: Im Rahmen des Gender Kollegs an der Universit t Wien entstand der von Eva-Maria Knoll und Birgit Sauer herausgegebene Band, in dem Aspekte ritual hnlicher, performativer Einübungsformen von Geschlechtlichkeit dargestellt werden. In den Beitr gen wird eine Strategie einer beschreibenden De-Ritualisierung, einer Dekonstruktion der Ritualisierungsformen von Geschlecht verfolgt. The volume edited by Eva-Maria Knoll and Birgit Sauer emerged from the work of the Center for Advanced Gender Studies (Gender Kolleg) at the University of Vienna. The volume presents aspects of ritualesque and performative forms of gender practice. The volume’s contributions trace the strategies of a descriptive de-ritualization, a deconstruction of forms of ritualization of gender.

Voices: A World Forum for Music Therapy , 2010,
Abstract: I travelled to Gera, where Dr. Christoph Schwabe met me [...] It was a cold, windy day, and we sat in front of the fireplace and talked for over two hours about his way toward music therapy, the development of music therapy in the German Democratic Republic (GDR), different influences and experiences within that field before 1989 and the changes that have taken place since then.
Verh ltnis Wissen, Wissenschaft und Geschlecht The Relationship between Knowledge, Science, and Gender
Anna Voigt
querelles-net , 2008,
Abstract: Im vorliegenden Band sind Beitr ge versammelt, die die Er ffnung eines Blicks für die umfassendere Betrachtung von Machtverh ltnissen in Bezug auf Wissensproduktion aus feministischer Perspektive zum Ziel haben. Bei den Lesern und Leserinnen wird dabei ein Verst ndnis für Transdisziplinarit t vorausgesetzt, da der Band Beitr ge enth lt, die traditionelle Disziplingrenzen bewusst überschreiten. The volume at hand collects essays that share the goal of opening up their readers’ view to include a more encompassing examination of power relations in the context of knowledge produced from feminist perspective. They assume, however, an understanding of transdisciplinarity in their readers, as the volume contains contributions that consciously cross the traditional disciplinary borders.
Kontextualisierung von Queer Theory Contextualizing Queer Theory

querelles-net , 2008,
Abstract: Christine M. Klapeer legt in diesem Einführungsband dar, aus welchen politischen und theoretischen Kontexten heraus sich queer‘ zu einem Begriff mit besonderem politischem und theoretischem Gehalt entwickelt hat. Wesentlich zielt sie dabei auf eine kritische Kontextualisierung von queer theory”. Die Autorin geht zun chst auf das Gay Liberation Movement ein, grenzt die Queer Theory vom Poststrukturalismus, von feministischen Theorien und den Lesbian and Gay Studies ab, beleuchtet Eckpunkte queeren Denkens und zeichnet schlie lich die Entwicklungen in sterreich sowohl politisch-rechtlich als auch bewegungsgeschichtlich und in der Wissenschaftslandschaft nach. Christine M. Klapeer’s introductory volume demonstrates the manner in which ‘queer’ grew out of various political and theoretical contexts to become a term with special political and theoretical content. She focuses primarily on a critical contextualization of “queer theory.” The author begins by approaching the Gay Liberation Movement and then distinguishes Queer Theory from poststructuralism, from feminist theories, and from Lesbian and Gay Studies. She continues on to illuminate the key aspects of queer thought and concludes by sketching the development in Austria in terms of politics and the law, the history of movements, and within the landscape of knowledge.
