Sicherheit und Zuverlässigkeit der Nebenschilddrüsenchirurgie bei Patienten mit Hyperparathyreoidismus und intraoperativ gemessenem intakten Parathormon
No full textIn der vorliegenden Arbeit wurde die Sicherheit und Zuverlässigkeit der Nebenschilddrüsenchirurgie beim Hyperparathyreoidismus mit intraoperativer Bestimmung des intakten Parathormons (Parathormonschnelltest) untersucht. Im Zeitrahmen zwischen 1/2004 und 12/2008 wurden an der universitären Klinik für viszerale Chirurgie und Medizin bei 194 operierten Patienten 150 Adenome, 39 Hyperplasien, sowie 5 Doppeladenome der Nebenschilddrüsen gefunden. Das intakte Parathormons (iPTH) im Serum wurde zu Beginn der Operation, nach Präparation der vergrösserten Nebenschilddrüse bei noch erhaltenem Gefässstiel, sowie 5, 10 und 15 Minuten nach der Parathyreoidektomie gemessen. Für den Erfolg der Operation wurde ein Abfall des iPTH um mehr als 50% vom Ausgangswert innerhalb der ersten 5 Minuten, sowie um mehr als 60% innerhalb der ersten 10 Minuten festgelegt. Bei solitären Adenomen der Nebenschilddrüse kam es bereits 5 Minuten nach der Parathyreoidektomie zu einem durchschnittlichen Abfall des iPTH um 61±19% vom Ausgangswert und nach 10 Minuten um 73±17%. Bei einer Hyperplasie der Nebenschilddrüse blieb dieser schnell eintretende steile Abfall des iPHT aus, der Rückgang des iPHT-Spiegels war zögerlich und erreichte erst nach subtotaler Parathyreoidektomie Normalwerte. In dem vorliegenden Patientengut wurden drei falsch-negative sowie ein falsch-positiver Befund beobachtet. Prognostisch ergibt sich für ein solitäres Adenom unserem Patientengut eine Sensitivität von 96% und eine Spezifität von 91% für den 10 Minuten-Wert. Der prädiktive Wert des positiven Tests beträgt 97%. Die vorliegende Arbeit zeigt, dass mit Hilfe der intraoperativen iPTH-Messung die Sicherheit in der Chirurgie des Parathyreoidismus gesteigert werden kann, vor allem beim Vorliegen eines Doppeladenoms oder bei schwierigen Rezidiveingriffen
Home, social work and intersectionality
No full textChapter 3 discusses intersectional and multidisciplinary research on home, contrasting this broad literature with how home is used in social work literature. It interrogates notions of home in social work and expands on previous literature about the embodied home visit and home as a dwelling or residence (see also Zufferey et al., 2020). Multidisciplinary and intersectional perspectives on home as imagined and experienced in movement presents home as being multiple and complex (Ahmed et al., 2003). This book builds on previous research and published literature by social work authors who advocate for interrogating home in social work (Zufferey et al., 2020). Previous social work research has positioned home as being beyond the ‘residential fixity’ of imagined homes, such as in child welfare (Forsberg andamp; Pösö, 2011). Social workers are involved in building civil society and a sense of place in migration and refugee resettlement work (Määttä, 2018) and they also co-construct a sense of home in collaboration with their clients (Ranta andamp; Juhila, 2020). Taking an intersectional approach to home in social work, this book explores how multidisciplinary literature has used intersectionality in their accounts of home. It argues for broadening definitions and responses to home in social work through a multidisciplinary and intersectional lens
Compiling questions into balanced quizzes about documents
No full textIn the educational framework, knowledge assessment is a critical component, and quizzes (sets of questions with concise answers) are a popular tool for this purpose. This paper focuses on the generation of balanced quizzes, i.e., quizzes that relate to a given set of documents, and to the central concepts described by the documents, in an evenly distributed manner. Our approach leverages a graph representing the relationships between questions, documents, and concepts, and phrases quiz construction as a node selection problem in this graph. We provide algorithms for constructing the graph and for selecting a good set of quiz questions. In our concrete implementation, we build quizzes for a collection of Wikipedia articles and evaluate them both with simulated students and with real human quiz takers, finding that our balanced quizzes are better suited at determining which articles the user has not read (corresponding to their knowledge gaps) than reasonable baselines

Le Premier Empereur et les lettrés. L'exécution de 212 avant J.-C
No full textNicolas Zufferey : The First Emperor and the Literati. The Execution of 212 B.C. Qin Shihuangdi (r. 221-210) was very often labelled an anti-Confucian emperor. Two famous measures taken during his reign were given as proof of it, namely the "burning of the books" in 213 B.C. and the "burying alive of scholars" one year later. These two events were closely linked together by posterity, as it is apparent from the set phrase/en shu keng ru, "to burn the books and bury (alive) the scholars." The execution of 212, however, says very little about the assumed anti-Confucian stand of Qin Shihuangdi : in all probability, the victims of the imperial wrath were mainly "magicians" who had deceived him ; the possible fact that some literati were killed too must be regarded as incidental. Notable evidence of it is the fact that many literati survived the Qin dynasty and were active during the first decades of the Han period, and that such an execution is not mentioned in early Han texts. The legend of an execution of literati was perhaps a creation of later scholars prone to vilify a sovereign reputed to be hostile to tradition and Confucianism. But the formation of the story was probably made easier by the vagueness of words such as ru or fangshi : ancient China literati concerned themselves with matters such as religious rites, astrology, or divination ; conversely, the "magicians" took for themselves some of the Confucian attributes. As a consequence, there was probably no sharp dividing line between the two groups. The word ru had sometimes a very broad meaning, and it might be the case in the phrase fen shu keng ru.Nicolas Zufferey : Le Premier Empereur et les lettrés. L'exécution de 212 avant J.-C.
Le sévere Premier Empereur (r. 221-210) de la dynastie Qin fut considéré par la tradition comme l'archétype du monarque anticonfucianiste : en furent donnés pour preuve l'autodafé des livres en 213 avant J.-C. et l'exécution des «lettrés» l'année suivante, deux événements rassemblés par la postérité dans la fameuse expression fen shu keng ru. L'exécution de 212, cependant, paraît n'avoir que peu de rapports avec le présumé anticonfucianisme de ce souverain. Les victimes de cette exécution furent bien plutôt les «magiciens» (fangshi), qui avaient trompé le Premier Empereur, que des «lettrés confucianistes» (ru). On constate en effet que bien des lettrés survivent à l'exécution, que le souverain les consulte encore après celle-ci ; et, surtout, que les auteurs du début des Han ne mentionnent aucune exécution de lettrés durant la dynastie Qin. Cette légende des lettrés martyrs fut peut-être une création de la postérité, dans le but de noircir un souverain réputé peu favorable aux idéaux confucianistes. Mais la formation de la légende fut sans doute favorisée par le flou des appellations : entre des ru qui s'occupent volontiers de rites religieux, d'astrologie, voire de divination, et des «magiciens » qui paraissent à l'occasion endosser les habits du confucianisme, la démarcation n'était pas nette. Le mot ru est susceptible de recouvrir des acceptions très variées en Chine ancienne et, dans l'expression fen shu keng ru, il convient sans doute de le comprendre dans un sens très large.Zufferey Nicolas.

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
