T1  - An extreme particle accelerator in the Galactic plane
BT  - HESS J1826-130
JF  - Astronomy and astrophysics : an international weekly journal
N2  - The unidentified very-high-energy (VHE; E > 0.1 TeV) gamma -ray source, HESS J1826-130, was discovered with the High Energy Stereoscopic System (HESS) in the Galactic plane. The analysis of 215 h of HESS data has revealed a steady gamma -ray flux from HESS J1826-130, which appears extended with a half-width of 0.21 degrees +/- 0.02 <br /> (stat)degrees <br /> stat degrees +/- 0.05 <br /> (sys)degrees sys degrees . The source spectrum is best fit with either a power-law function with a spectral index Gamma = 1.78 +/- 0.10(stat) +/- 0.20(sys) and an exponential cut-off at 15.2 <br /> (+5.5)(-3.2) -3.2+5.5 TeV, or a broken power-law with Gamma (1) = 1.96 +/- 0.06(stat) +/- 0.20(sys), Gamma (2) = 3.59 +/- 0.69(stat) +/- 0.20(sys) for energies below and above E-br = 11.2 +/- 2.7 TeV, respectively. The VHE flux from HESS J1826-130 is contaminated by the extended emission of the bright, nearby pulsar wind nebula, HESS J1825-137, particularly at the low end of the energy spectrum. Leptonic scenarios for the origin of HESS J1826-130 VHE emission related to PSR J1826-1256 are confronted by our spectral and morphological analysis. In a hadronic framework, taking into account the properties of dense gas regions surrounding HESS J1826-130, the source spectrum would imply an astrophysical object capable of accelerating the parent particle population up to greater than or similar to 200 TeV. Our results are also discussed in a multiwavelength context, accounting for both the presence of nearby supernova remnants, molecular clouds, and counterparts detected in radio, X-rays, and TeV energies.

T1  - Very high energy γ-ray emission from two blazars of unknown redshift and upper limits on their distance
JF  - Monthly Notices of the Royal Astronomical Society
N2  - We report on the detection of very high energy (VHE; E > 100 GeV) gamma-ray emission from the BL Lac objects KUV 00311-1938 and PKS 1440-389 with the High Energy Stereoscopic System (H.E.S.S.). H.E.S.S. observations were accompanied or preceded by multiwavelength observations with Fermi/LAT, XRT and UVOT onboard the Swift satellite, and ATOM. Based on an extrapolation of the Fermi/LAT spectrum towards the VHE gamma-ray regime, we deduce a 95 per cent confidence level upper limit on the unknown redshift of KUV 00311-1938 of z < 0.98 and of PKS 1440-389 of z < 0.53. When combined with previous spectroscopy results, the redshift of KUV 00311-1938 is constrained to 0.51 <= z < 0.98 and of PKS 1440-389 to 0.14 (sic) z < 0.53.

T1  - Say it with double flowers
JF  - Journal of experimental botany
N2  - Every year, lovers world-wide rely on mutants to show their feelings on Valentine's Day. This is because many of the most popular ornamental flowering plants have been selected to form extra petals at the expense of reproductive organs to enhance their attractiveness and aesthetic value to humans. This so-called 'double flower' (DF) phenotype, first described more than 2000 years ago (Meyerowitz et al., 1989) is present, for example, in many modern roses, carnations, peonies, and camellias. Gattolin et al. (2020) now identify a unifying explanation for the molecular basis of many of these DF cultivars.

BT  - understanding the impact of appearance disclosure on accommodation sharing platforms
T2  - Proceedings of the 53rd Hawaii International Conference on System Sciences
N2  - Online photographs govern an individual’s choices across a variety of contexts. In sharing arrangements, facial appearance has been shown to affect the desire to collaborate, interest to explore a listing, and even willingness to pay for a stay. Because of the ubiquity of online images and their influence on social attitudes, it seems crucial to be able to control these aspects. The present study examines the effect of different photographic self-disclosures on the provider’s perceptions and willingness to accept a potential co-sharer. The findings from our experiment in the accommodation-sharing context suggest social attraction mediates the effect of photographic self-disclosures on willingness to host. Implications of the results for IS research and practitioners are discussed.

T1  - Verwaltungsmodernisierung
BT  - Digitalisierung und Partizipation
T3  - KWI Schriften
N2  - Die Modernisierung der öffentlichen Verwaltung hat sich längst zu einer Daueraufgabe entwickelt. In den Modernisierungsprozessen stehen derzeit zwei Segmente besonders im Fokus: Digitalisierung und Partizipation. Digitalisierung geht heute weit über die ursprünglich mit diesem Stichwort angesprochene Umwandlung analoger Daten in elektronische Datenformate hinaus. Die Programmatik der Digitalisierung zielt auf den möglichst umfassenden Einsatz elektronischer Informations- und Kommunikationstechniken zur Unterstützung, Beschleunigung, Rationalisierung und in Teilen auch Ersetzung von herkömmlichen Verwaltungsabläufen mit der Perspektive auf eine Transformation und Durchdringung sowohl des gesamten Verwaltungshandelns als auch der gesamten Verwaltungsorganisation. Demgegenüber meint Partizipation nach gängigem Verständnis die Beteiligung von Bürgern und anderen gesellschaftlichen Akteuren an politischen Willensbildungs- und Entscheidungsprozessen. In spezifisch administrativem Zusammenhang geht es vor allem um die Einbindung von Bürgern in Entscheidungsprozesse der Verwaltung und um die Aktivierung der Zivilgesellschaft, die Erschließung bürgerschaftlichen Engagements sowie gesellschaftlicher Ressourcen für die Erfüllung von Verwaltungsaufgaben – und dies alles mit dem Ziel einer Verbesserung der Legitimität und Qualität öffentlicher Verwaltung. Die beiden Modernisierungsansätze stehen nicht unverbunden nebeneinander. Vielmehr gehen sie nicht selten ineinander über. Beispiele dafür sind die Bereitstellung von Optionen zu elektronischer Stellung und Bearbeitung von Anträgen sowie von elektronischen Plattformen für die Bürgerpartizipation.

An diesen Themenfeldern der Verwaltungsmodernisierung setzt der Tagungsband an. Er dokumentiert den Gedankenaustausch über Digitalisierungs- und Partizipationsprozesse zwischen polnischen und deutschen Verwaltungsrechtswissenschaftlern auf einer Tagung, die im Dezember 2019 an der Universität Potsdam stattgefunden hat.

T1  - The impact of salient action effects on 6-, 7-, and 11-month-olds’ goal-predictive gaze shifts for a human grasping action
JF  - PLOS ONE
N2  - When infants observe a human grasping action, experience-based accounts predict that all infants familiar with grasping actions should be able to predict the goal regardless of additional agency cues such as an action effect. Cue-based accounts, however, suggest that infants use agency cues to identify and predict action goals when the action or the agent is not familiar. From these accounts, we hypothesized that younger infants would need additional agency cues such as a salient action effect to predict the goal of a human grasping action, whereas older infants should be able to predict the goal regardless of agency cues. In three experiments, we presented 6-, 7-, and 11-month-olds with videos of a manual grasping action presented either with or without an additional salient action effect (Exp. 1 and 2), or we presented 7-month-olds with videos of a mechanical claw performing a grasping action presented with a salient action effect (Exp. 3). The 6-month-olds showed tracking gaze behavior, and the 11-month-olds showed predictive gaze behavior, regardless of the action effect. However, the 7-month-olds showed predictive gaze behavior in the action-effect condition, but tracking gaze behavior in the no-action-effect condition and in the action-effect condition with a mechanical claw. The results therefore support the idea that salient action effects are especially important for infants' goal predictions from 7 months on, and that this facilitating influence of action effects is selective for the observation of human hands.

T1  - In Search of the Utopian States of America
BT  - Intentional Communities in Novels of the Long Nineteenth Century
T2  - Palgrave Studies in Utopianism
N2  - This book endeavours to understand the seemingly direct link between utopianism and the USA, discussing novels that have never been brought together in this combination before, even though they all revolve around intentional communities: Imlay’s The Emigrants (1793), Hawthorne’s The Blithedale Romance (1852), Howland’s Papas Own Girl (1874), Griggs’s Imperium in Imperio (1899), and Du Bois’s The Quest of the Silver Fleece (1911). They relate nation and utopia not by describing perfect societies, but by writing about attempts to immediately live radically different lives. Signposting the respective communal history, the readings provide a literary perspective to communal studies, and add to a deeply necessary historicization for strictly literary approaches to US utopianism, and for studies that focus on Pilgrims/Puritans/Founding Fathers as utopian practitioners. This book therefore highlights how the authors evaluated the USA’s utopian potential and traces the nineteenth-century development of the utopian imagination from various perspectives.
