Familie - Generation - Institution. Generationenkonzepte in der Vormoderne

Dieser Band versammelt Beiträge zu Generationenbeziehungen und Generationenkonzepten in der Vormoderne, die auf eine Tagung des DFG-Graduiertenkollegs 'Generationenbewusstsein und Generationenkonflikte in Antike und Mittelalter' in Bamberg zurückgehen. Die behandelten Untersuchungsgegenstände reichen von den antiken Diadochenreichen über die ottonische Königsfamilie des 10. und 11. Jahrhunderts bis zum frühneuzeitlichen Landadel Westfalens. Dabei werden historische, literaturwissenschaftliche und soziologische Fragestellungen aufgegriffen, um den Erkenntniswert des Konzepts 'Generation' interdisziplinär zu diskutieren.This volume brings together contributions on generational relations and concepts of generation in Early Modernity given on the occasion of a conference organized at Bamberg by the Research Training Group of the German Research Foundation (DFG) 'Generational Awareness and Generational Conflicts in Antiquity and the Middle Ages'. The topics ranged from the ancient Diadoch kingdoms to the history of the Ottonian royal family of the 10th and 11th centuries and the early modern landed gentry in Westfalia. Addressing questions from historical, literary and social studies the validity of the concept of 'generation' was discussed among scholars and students from a variety of disciplines

Giovanni Boccaccio. Italienisch-deutscher Kulturtransfer von der Frühen Neuzeit bis zur Gegenwart

Italien und Deutschland – kaum zwei andere Kulturen in Europa sind so stark miteinander verbunden wie diese beiden, sei es geschichtlich oder kulturell. Am wirkmächtigsten war sicherlich die Übernahme des Gedankenguts der italienischen Renaissance, in deren Folge Wissen aus gesellschaftlichen, wissenschaftlichen und kulturellen Bereichen den Weg nach Deutschland fand, darunter auch die Kenntnis von Giovanni Boccaccios Werken, die sich auf deutschsprachige Kontexte auswirkten. Der vorliegende Tagungsband versammelt die Beiträge zur gleichnamigen Tagung „Giovanni Boccaccio. Italienisch-deutscher Kulturtransfer von der Frühen Neuzeit bis zur Gegenwart“ (Bamberg, 21. bis 23. November 2013), die sich mit vielfältigen Aspekten der Boccaccio-Rezeption auseinandersetzen

Blockbuster Middle Ages. Proceedings of the Postgraduate Conference Bamberg 2015

Im Mittelpunkt des aus einer im Jahr 2015 in Bamberg abgehaltenen Nachwuchstagung hervorgegangenen Bandes steht die Mittelalterrezeption in filmischen und seriellen Großproduktionen. Der Blockbuster-Begriff spielt dabei insofern eine wichtige Rolle, als er die mediale Ware ‚Mittelalter‘ sowohl von Produktions- als auch Publikumsseite in den Blick nimmt, die beide an der Erzeugung des Phänomens ‚Blockbuster‘ beteiligt sind. Dass seit dem Aufkommen solcher finanziell hochaufwändigen, auf spektakuläre Schauwerte setzenden Produktionen in den 50er- und 60er Jahren kaum ein Jahr vergangen ist, in denen die Major-Studios nicht einen Mittelalterfilm ‚Marke Hollywood‘ veröffentlicht haben, lässt auf ein anhaltendes ökonomisches Potential mittelalterbezogener Produktionen und damit auf eine stabile Beliebtheit auf Seiten der Rezipienten schließen. Den Gesetzen von Angebot und Nachfrage folgend, beeinflusst das globale Kinopublikum damit zwar einerseits den Filmmarkt mit, gleichzeitig prägen, transportieren und perpetuieren die dadurch entstehenden, international mit großer Reichweite verbreiteten Filme das Mittelalterbild ihrer ZuschauerInnen stark. Die 21 Beiträge des Tagungsbandes widmen sich dem Phänomen ‚Mittelalter im Blockbusterkino‘ inhaltlich, beschäftigen sich aber auch mit der Notwendigkeit seiner Reflexion und den Bedingungen seines gewinnbringenden Einsatzes in Lehre und Unterricht

Shift Work in Nurses: Contribution of Phenotypes and Genotypes to Adaptation

Daily cycles of sleep/wake, hormones, and physiological processes are often misaligned with behavioral patterns during shift work, leading to an increased risk of developing cardiovascular/metabolic/gastrointestinal disorders, some types of cancer, and mental disorders including depression and anxiety. It is unclear how sleep timing, chronotype, and circadian clock gene variation contribute to adaptation to shift work.Newly defined sleep strategies, chronotype, and genotype for polymorphisms in circadian clock genes were assessed in 388 hospital day- and night-shift nurses.Night-shift nurses who used sleep deprivation as a means to switch to and from diurnal sleep on work days (∼25%) were the most poorly adapted to their work schedule. Chronotype also influenced efficacy of adaptation. In addition, polymorphisms in CLOCK, NPAS2, PER2, and PER3 were significantly associated with outcomes such as alcohol/caffeine consumption and sleepiness, as well as sleep phase, inertia and duration in both single- and multi-locus models. Many of these results were specific to shift type suggesting an interaction between genotype and environment (in this case, shift work).Sleep strategy, chronotype, and genotype contribute to the adaptation of the circadian system to an environment that switches frequently and/or irregularly between different schedules of the light-dark cycle and social/workplace time. This study of shift work nurses illustrates how an environmental "stress" to the temporal organization of physiology and metabolism can have behavioral and health-related consequences. Because nurses are a key component of health care, these findings could have important implications for health-care policy

An embedding technique to determine ττ backgrounds in proton-proton collision data

An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe

Measurement of the Splitting Function in &ITpp &ITand Pb-Pb Collisions at root&ITsNN&IT=5.02 TeV

Data from heavy ion collisions suggest that the evolution of a parton shower is modified by interactions with the color charges in the dense partonic medium created in these collisions, but it is not known where in the shower evolution the modifications occur. The momentum ratio of the two leading partons, resolved as subjets, provides information about the parton shower evolution. This substructure observable, known as the splitting function, reflects the process of a parton splitting into two other partons and has been measured for jets with transverse momentum between 140 and 500 GeV, in pp and PbPb collisions at a center-of-mass energy of 5.02 TeV per nucleon pair. In central PbPb collisions, the splitting function indicates a more unbalanced momentum ratio, compared to peripheral PbPb and pp collisions.. The measurements are compared to various predictions from event generators and analytical calculations.Peer reviewe

Electroweak production of two jets in association with a Z boson in proton-proton collisions root s =13 TeV

A measurement of the electroweak (EW) production of two jets in association with a Z boson in proton-proton collisions at root s = 13 TeV is presented, based on data recorded in 2016 by the CMS experiment at the LHC corresponding to an integrated luminosity of 35.9 fb(-1). The measurement is performed in the lljj final state with l including electrons and muons, and the jets j corresponding to the quarks produced in the hard interaction. The measured cross section in a kinematic region defined by invariant masses m(ll) > 50 GeV, m(jj) > 120 GeV, and transverse momenta P-Tj > 25 GeV is sigma(EW) (lljj) = 534 +/- 20 (stat) fb (syst) fb, in agreement with leading-order standard model predictions. The final state is also used to perform a search for anomalous trilinear gauge couplings. No evidence is found and limits on anomalous trilinear gauge couplings associated with dimension-six operators are given in the framework of an effective field theory. The corresponding 95% confidence level intervals are -2.6 <cwww/Lambda(2) <2.6 TeV-2 and -8.4 <cw/Lambda(2) <10.1 TeV-2. The additional jet activity of events in a signal-enriched region is also studied, and the measurements are in agreement with predictions.Peer reviewe

Bose-Einstein correlations of charged hadrons in proton-proton collisions at s\sqrt s = 13 TeV

Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at $\sqrt{s}$ = 13 TeV. The results are based on data collected using the CMS detector at the LHC during runs with a special low-pileup configuration. Three analysis techniques with different degrees of dependence on simulations are used to remove the non-Bose-Einstein background from the correlation functions. All three methods give consistent results. The measured lengths of homogeneity are studied as functions of particle multiplicity as well as average pair transverse momentum and mass. The results are compared with data from both CMS and ATLAS at $\sqrt{s}$ = 7 TeV, as well as with theoretical predictions.[graphic not available: see fulltext]Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at $\sqrt{s} =$ 13 TeV.

Search for dark matter in events with a leptoquark and missing transverse momentum in proton-proton collisions at 13 TeV

A search is presented for dark matter in proton-proton collisions at a center-of-mass energy of root s= 13 TeV using events with at least one high transverse momentum (p(T)) muon, at least one high-p(T) jet, and large missing transverse momentum. The data were collected with the CMS detector at the CERN LHC in 2016 and 2017, and correspond to an integrated luminosity of 77.4 fb(-1). In the examined scenario, a pair of scalar leptoquarks is assumed to be produced. One leptoquark decays to a muon and a jet while the other decays to dark matter and low-p(T) standard model particles. The signature for signal events would be significant missing transverse momentum from the dark matter in conjunction with a peak at the leptoquark mass in the invariant mass distribution of the highest p(T) muon and jet. The data are observed to be consistent with the background predicted by the standard model. For the first benchmark scenario considered, dark matter masses up to 500 GeV are excluded for leptoquark masses m(LQ) approximate to 1400 GeV, and up to 300 GeV for m(LQ) approximate to 1500 GeV. For the second benchmark scenario, dark matter masses up to 600 GeV are excluded for m(LQ) approximate to 1400 GeV. (C) 2019 The Author(s). Published by Elsevier B.V.Peer reviewe

Search for an L-mu - L-tau gauge boson using Z -> 4 mu events in proton-proton collisions at root s=13 TeV

A search for a narrow Z' gauge boson with a mass between 5 and 70 GeV resulting from an L-mu - L-tau U (1) local gauge symmetry is reported. Theories that predict such a particle have been proposed as an explanation of various experimental discrepancies, including the lack of a dark matter signal in direct-detection experiments, tension in the measurement of the anomalous magnetic moment of the muon, and reports of possible lepton flavor universality violation in B meson decays. A data sample of proton-proton collisions at a center-of-mass energy of 13 TeV is used, corresponding to an integrated luminosity of 77.3 fb(-1) recorded in 2016 and 2017 by the CMS detector at the LHC. Events containing four muons with an invariant mass near the standard model Z boson mass are analyzed, and the selection is further optimized to be sensitive to the events that may contain Z -> Z'mu mu -> 4 mu decays. The event yields are consistent with the standard model predictions. Upper limits of 10(-8)-10(-7) at 95% confidence level are set on the product of branching fractions B(Z -> Z'mu mu)B(Z' -> mu mu), depending on the Z' mass, which excludes a Z' boson coupling strength to muons above 0.004-0.3. These are the first dedicated limits on L-mu - L-tau models at the LHC and result in a significant increase in the excluded model parameter space. The results of this search may also be used to constrain the coupling strength of any light Z' gauge boson to muons. (C) 2019 The Author(s). Published by Elsevier B.V.Peer reviewe
