Zeigen, nicht erklären!
(2020)
Medien sind während der Covid-Pandemie in besonderem Maße gefordert, komplexe Sachverhalte, wie Inzidenzen und exponentielles Wachstum einfach zu erklären. Informationsgrafiken sind dazu bestens geeignet, erfordern allerdings hohe Kompetenz in der Erstellung. Dieser Artikel plädiert für die Einführung eines eigenen journalistischen Genres, nämlich des visuellen Journalismus.

Wirtschaftsethik
(2020)
Wirtschaftliche und ethische Handlungen sind zugleich realisierbar, wenn zwischen einer einrahmenden Wirtschaftsordnung (Spielregeln) und einzelnen Handlungen (Spielzügen) unterschieden wird. Das wirtschaftliche Tun und Unterlassen wird dann in den Spielzügen und die Ethik über die Spielregeln realisierbar. Die Gültigkeit einer Wirtschaftsordnung setzt einen allgemeinen Konsens über die Spielregeln und die Durchsetzungsinstanzen (z. B: Justiz oder Kartellamt) voraus. Dann regelt sie den Wettbewerb und nötigt Anbieter, sich an den Interessen der Nachfrager zu orientieren und dabei auf einen effizienten Ressourceneinsatz zu achten. So erfolgt das individuelle Handeln der Marktteilnehmer in der einrahmenden Wirtschaftsordnung mit den darin befindlichen Anreizen, daher spricht man von einer Anreizethik. Mit ihr werden wirtschaftliche und ethische Handlungen zugleich realisierbar.
Was Kennzahlen aussagen
(2021)
Was ist als Ergebnis der Operation 1 : 2 als „korrekt“ anzuerkennen? In der Menge der natürlichen Zahlen N ist 0 korrekt, in der Menge der rationalen Zahlen Q ist 0,5 richtig. Was „wahr“ ist, hängt also von den Ermittlungs- und Berechnungsgrundlagen ab. Das übersehen viele Führungskräfte beim Umgang mit Kennzahlen genau so, wie die Bedeutung ihrer kommunikativen Kompetenzen.

Objectives: The MetabQoL 1.0 is the first disease-specific health related quality of life (HrQoL) questionnaire for patients with intoxication-type inherited metabolic disorders. Our aim was to assess the validity and reliability of the MetabQoL 1.0, and to investigate neuropsychiatric burden in our patient population. Methods: Data from 29 patients followed at a single center, aged between 8 and 18 years with the diagnosis of methylmalonic acidemia (MMA), propionic acidemia (PA) or isovaleric acidemia (IVA), and their parents were included. The Pediatric Quality of Life Inventory (PedsQoL) was used to evaluate the validity and reliability of MetabQoL 1.0.
Results: The MetabQoL 1.0 was shown to be valid and reliable (Cronbach's alpha: 0.64–0.9). Fourteen out of the 22 patients (63.6%) formally evaluated had neurological findings. Of note, 17 out of 20 patients (85%) had a psychiatric disorder when evaluated formally by a child and adolescent psychiatrist. The median mental scores of the MetabQoL 1.0 proxy report were significantly higher than those of the self report (p = 0.023). Patients with neonatal-onset disease had higher MetabQoL 1.0 proxy physical (p = 0.008), mental (p = 0.042), total scores (p = 0.022); and self report social (p = 0.007) and total scores (p = 0.043) than those with later onset disease.
Conclusions: This study continues to prove that the MetabQoL 1.0 is an effective tool to measure what matters in intoxication-type inherited metabolic disorders. Our results highlight the importance of clinical assessment complemented by patient reported outcomes which further expands the evaluation toolbox of inherited metabolic diseases.

The dynamics of self-adaptive multi-recombinant evolution strategies on the general ellipsoid model
(2014)
Why do some countries assign a major role to wind energy in decarbonizing their electricity systems, while others are much less committed to this technology? We argue that processes of (de-)legitimation, driven by discourse coalitions who strategically employ certain storylines in public debates, provide part of the answer. To illustrate our approach, we comparatively investigate public discourses surrounding wind energy in Austria and Switzerland, two countries that differ strongly in wind energy deployment. By combining a qualitative content analysis and a discourse network analysis of 808 newspaper articles published 2010–2020, we identify four distinct sets of storylines used to either delegitimize or legitimize the technology. Our study indicates that low deployment rates in Switzerland can be related to the prominence of delegitimizing storylines in the public discourse, which result in a rather low socio-political acceptance of wind energy. In Austria, by contrast, there is more consistent support for wind energy by discourse coalitions using a broad set of legitimizing storylines. By bridging the related but separate literatures of technology legitimacy and social acceptance, our study contributes to a better understanding of socio-political conflict and divergence in low-carbon technological pathways.
A Telecom optical fibers are still being the best transmission medium of digital data and analogue signals for long distance applications. Progress in integrated photonics enables development of photonic chips with new unique properties, circuits of the future, and overcomes current limits in information and communication technologies. The packaging of photonic chips is necessary for taking them out of research laboratories into real implementation in the information and communication technology applications. One important step of packaging is effective coupling of optical radiation between telecom optical fiber with ten microns core dimension and photonic chip optical waveguide with submicron dimensions. For complex photonic chips, it is necessary to couple not one optical fiber but several optical fibers, which are arranged in fiber arrays. In this case, it is necessary to use a 6D positioning system, which allows to optimally adjust the relative position of the photonic chip and the fiber arrays. After setting the optimal relative position of the photonic chip and the fiber array, the process of their fixation follows. One possibility of fixation is gluing with an adhesive in the optical path between the photonic chip and an array of optical fibers with a refractive index close to the refractive index of the optical fiber core. This paper is focused on the experimental test set-up for the temperature characterization of fiber array to photonics chip butt coupling at 1310 nm and 1550 nm wavelengths fixed themselves by UV adhesive in the optical path. The main aims of this works are selection of better adhesive from two types for gluing of photonic chip and fiber array in packaging process of photonics chips and validation of gluing process developing. The coupling and alignment of fiber arrays to photonics chip were done by automated active alignments system and they were fixed themselves by curable epoxy adhesive. Temperature changes of coupling insertion losses are measured and investigated for two different UV adhesives during three temperature cycles from -40 °C to 80 °C in climatic chamber according to Telcordia. Spectral dependence of insertion losses were measured and compared before and after three temperature cycles for 1530 nm to 1570 nm spectral range at room temperature.

Spielregeln und Spielzüge
(2020)
Die Gültigkeit einer Wirtschaftsordnung (Spielregeln) verlangt den Beteiligten einen allgemeinen Konsens, der sich auch auf die Durchsetzungsinstanzen (Schiedsrichter) bezieht. Es fragt sich, auf welcher Basis dieser Konsens über die Geltung von Spielregeln, Spielzügen und regelkonform sanktionierenden Schiedsrichtern beruht und gibt es dafür benötige Vorbedingungen?
Der Einsatz von Robotik im Pflegekontext wird kontrovers diskutiert und löst unterschiedliche Assoziationen aus. In diesem Beitrag stellen wir Ergebnisse aus einer schriftlichen Befragung bei Pflegekräften aus Deutschland vor. Es wird aufgezeigt, für welche Funktionen und Aufgaben sich Pflegekräfte den Einsatz von Roboter vorstellen können und wo gegensätzliche Einstellungen gegenüber Robotern bestehen. Ein Fallbeispiel illustriert ein mögliches Anwendungsfeld. Mit den reflexiven Fragen laden wir die:den Lesenden ein, sich selbst mit der Idee Roboter als Alltagshelfer für ältere Menschen auseinanderzusetzen.
Signatures of the optical stark effect on entangled photon pairs from resonantly-pumped quantum dots
(2023)
Two-photon resonant excitation of the biexciton-exciton cascade in a quantum dot generates highly polarization-entangled photon pairs in a near-deterministic way. However, the ultimate level of achievable entanglement is still debated. Here, we observe the impact of the laser-induced ac-Stark effect on the quantum dot emission spectra and on entanglement. For increasing pulse-duration-to-lifetime ratios and pump powers, decreasing values of concurrence are recorded. Nonetheless, additional contributions are still required to fully account for the observed below-unity concurrence.

Maßnahmen zur Planung, zum Aufbau und zur Steuerung einer Wertschöpfungsarchitektur entfalten ihre Wirkung, wenn sie kontextsensitiv entwickelt und umgesetzt werden. Zu diesem Kontext gehören Strukturen und Prozesse der geplanren Vorgehensweise, ermittelbare Daten und Informationen über das eigene Tun sowie Erwartungen und Verhaltensweisen aller Beteiligten. Im Kern der Bemühungen sollte die Mitgestaltung kommunikativer Prozesse der gemeinsamen Verständigung sein, denn ihre Resonanzen sind die Bezugspunkte für das weitere Tun. Daher gilt: Der betriebswirtschaftliche Erfolg wird maßgeblich geprägt durch die Qualität der Verständigung.

Die zu bearbeitenden Problemstellungen hingegen beachten keinerlei Grenzen von Fachdisziplinen, Fachabteilungen oder Verantwortungsbereichen.
