Authentic Corporate Social Responsibility Based on Authentic Empowerment: An Exemplary Business Leadership Case

Authors Dillon, Back, and Manz examine the underpinnings of genuine or authentic Corporate Social Responsibility (CSR), noting the direct nexus between stakeholder empowerment and the socially-responsible actions of authentic leaders. Such an empowering leadership approach– involving structural, psychological, developmental, and financial components – is particularly exemplified by a family-owned (Back) wine and cheese company (Fairview Trust), situate in South Africa

Therapie der CED bei Steroidversagen: Immunsuppressiva oder Biologika?

Zusammenfassung: Trotz oftmals erfolgreichem Einsatz von systemischen Steroiden in der Behandlung von Patienten mit aktiver chronisch-entzündlicher Darmerkrankung (CED) sind Limitationen vorhanden aufgrund von primärem Nichtansprechen, Steroidabhängigkeit sowie Steroidresistenz. Eine Langzeittherapie mit Steroiden ist im Hinblick auf die bekannten Nebenwirkungen zu vermeiden. Dieser Artikel erläutert Indikationen für den Einsatz von Immunmodulatoren (Azathioprin, 6-Mercaptopurin, Methotrexat), Medikamenten gegen Tumornekrosefaktor (Anti-TNF-Therapie) sowie Calcineurininhibitoren (Ciclosporin, Tacrolimus) bei Steroidresisten

Magnetic Response of Magnetospirillum Gryphiswaldense

In this study we modelled and measured the U-turn trajectories of individual magnetotactic bacteria under the application of rotating magnetic fields, ranging in ampitude from 1 to 12 mT. The model is based on the balance between rotational drag and magnetic torque. For accurate verification of this model, bacteria were observed inside 5 m tall microfluidic channels, so that they remained in focus during the entire trajectory. From the analysis of hundreds of trajectories and accurate measurements of bacteria and magnetosome chain dimensions, we confirmed that the model is correct within measurement error. The resulting average rate of rotation of Magnetospirillum Gryphiswaldense is 0.74 +- 0.03 rad/mTs.Comment: 17 pages, 12 figure

Magneto-optical study of electron occupation and hole wave functions in stacked self-assembled InP quantum dots

We have studied the magnetophotoluminescence of doubly stacked layers of self-assembled InP quantum dots in a GaInP matrix. 4.0±0.1 monolayers of InP were deposited in the lower layer of each sample, whereas in the upper layer 3.9, 3.4, and 3.0 monolayers were used. Low-temperature photoluminescence measurements in zero magnetic field are used to show that, in each case, only one layer of dots is occupied by an electron, and imply that when the amount of InP in both layers is the same, the dots in the upper layer are larger. High-field photoluminescence data reveal that the position and extent of the hole wave function are strongly dependent on the amount of InP in the stack. ©2001 American Institute of Physics

ANNIVERSARIES, THE PUBLIC, AND ACADEMIA

Anniversaries have been much problematised in scholarship, not least in the present special number. But pragmatically, they are also a tried‐and‐tested way of engaging with diverse publics. In contemporary British Higher Education, such work is incentivised through the impact agenda of the Research Excellence Framework. The following contribution brings together three British‐based colleagues in German Studies, who each reflect on their own practical experiences of capitalising on anniversaries. Henrike Lähnemann discusses commemorative activities and events 500 years after the Reformation, in which she uses translating, printing, and singing as historic impact‐style activities to engage audiences in Oxford and beyond. Seán Williams turns to mainstream media, arguing that anniversaries are a useful hook for bringing German Studies content to wider audiences – even if the commemorative occasions seem, on the face of it, less relevant to those of us working in increasingly marginal disciplines in Great Britain. Stefan Manz is concerned with remembering the forgotten ‘collateral’ victims of the First World War during the centenary, particularly those Germans who were interned in camps throughout the British Empire. Manz shows that it is possible to connect the stories of the marginalised to large‐scale anniversaries in order to challenge dominant narratives. Here, as in all cases, the key to success is cross‐sector collaboration and adaptation to non‐academic needs and contexts

The I-mode confinement regime at ASDEX Upgrade: global propert ies and characterization of strongly intermittent density fluctuations

Properties of the I­mode confinement regime on the ASDEX Upgrade tokamak are summarized. A weak dependence of the power threshold for the L­I transition on the toroidal magnetic field strength is found. During improved confinement, the edge radial electric field well deepens. Stability calculations show that the I­mode pedestal is peeling­ballooning stable. Turbulence investigations reveal strongly intermittent density fluctuations linked to the weakly coherent mode in the confined plasma, which become stronger as the confinement quality increases. Across all investigated structure sizes ( ≈ ⊥ k 5 – 12 cm − 1 , with ⊥ k the perpendicular wavenumber of turbulent density fluctuations), the intermittent turbulence bursts are observed. Comparison with bolometry data shows that they move poloidally toward the X­point and finally end up in the divertor. This might be indicative that they play a role in inhibiting the density profile growth, such that no pedestal is formed in the edge density profile.European Union (EUROfusion 633053)European Union (EUROfusion AWP15­ENR­09/IPP­02

Multi-layer atom chips for versatile atom micro manipulation

We employ a combination of optical UV- and electron-beam-lithography to create an atom chip combining sub-micron wire structures with larger conventional wires on a single substrate. The new multi-layer fabrication enables crossed wire configurations, greatly enhancing the flexibility in designing potentials for ultra cold quantum gases and Bose-Einstein condensates. Large current densities of >6 x 10^7 A/cm^2 and high voltages of up to 65 V across 0.3 micron gaps are supported by even the smallest wire structures. We experimentally demonstrate the flexibility of the next generation atom chip by producing Bose-Einstein condensates in magnetic traps created by a combination of wires involving all different fabrication methods and structure sizes.Comment: 4 pages, 5 figure

How much do adults sit? Result from the German Health Update (GEDA 2019/2020-EHIS)

Background: Sedentary behaviour is increasingly perceived as a risk factor for the development of diseases and for increased mortality. In particular, increased time spent sitting in combination with low physical activity seems to have negative health consequences. Methods: In the nationwide cross-sectional study German Health Update (GEDA 2019/2020-EHIS), the indicator ‘sitting’ was captured by the self-report of the participants. Results: For at least eight hours a day, 16.7% of women and 22.3% of men sit: Men more often than women, younger persons more often than older persons and the proportion increases significantly from the low to the high education group. Similarly, about one fifth of adults in Germany sit for at least four hours a day and do not engage in physical activity in their leisure time. Conclusion: The results indicate that preventive measures are needed to reduce time spent sitting and increase physical activit

Performance of the ATLAS Precision Muon Chambers under LHC Operating Conditions

For the muon spectrometer of the ATLAS detector at the large hadron collider (LHC), large drift chambers consisting of 6 to 8 layers of pressurized drift tubes are used for precision tracking covering an active area of 5000 m2 in the toroidal field of superconducting air core magnets. The chambers have to provide a spatial resolution of 41 microns with Ar:CO2 (93:7) gas mixture at an absolute pressure of 3 bar and gas gain of 2?104. The environment in which the chambers will be operated is characterized by high neutron and background with counting rates of up to 100 per square cm and second. The resolution and efficiency of a chamber from the serial production for ATLAS has been investigated in a 100 GeV muon beam at photon irradiation rates as expected during LHC operation. A silicon strip detector telescope was used as external reference in the beam. The spatial resolution of a chamber is degraded by 4 ?m at the highest background rate. The detection efficiency of the drift tubes is unchanged under irradiation. A tracking efficiency of 98% at the highest rates has been demonstrated
