description: »Keine Buchung ohne Beleg«. Dieser Grundsatz des Rechnungswesens scheint im Zuge der Digitalisierung von Verwaltungsprozessen als zunehmend antiquiert, da zumeist – noch – der physische Papierbuchungsbeleg als Grundlage und Nachweis für die Richtigkeit der Aufzeichnung assoziiert wird. Mit der Einführung der elektronischen Rechnung oder »E-Rechnung« an der Technischen Universität Hamburg (TUHH) wird ein wichtiger Meilenstein in der Digitalisierung von Verwaltungsprozessen verwirklicht. Mit der Einführung der E-Rechnung ist die Digitalisierung des Rechnungswesens keineswegs abgeschlossen, sondern ein weiteres Element in einem dynamischen Prozess. So ist stets aufs Neue auszuloten, wie interne und externe Einflüsse auf die Weiterentwicklung der Digitalisierung des Rechnungswesens einwirken, welche Konsequenzen sich daraus ergeben und wie damit umzugehen ist. Ein wichtiges Instrument zum erfolgreichen Gelingen ist die kommunikative Begleitung des Prozesses. So ist es nicht sonderlich überraschend, dass viele Fragen nach dem »Wie?«, »Wer?«, »Wo?«, »Was?« und »Warum?« formuliert wurden und werden. In diesem Beitrag sollen Antworten auf diese Fragen in Bezug auf die TUHH gegeben werden. In der zweiten Auflage ist die wesentliche inhaltliche Neuerung die Umsetzung einer Prozessverschlankung als Konsequenz der Reflexion über die gesammelten Erfahrungen aus dem laufenden Universitätsbetrieb.

description: Marketing- und Vertriebsniederlassungen, welche in einem anderen Land als der Hauptsitz residieren, benötigen eine Sicherstellung der Liquidität in regelmässigen Abständen, um lokale Spesen, Miet- und Salärzahlungen zu ermöglichen. Normalerweise wird diese Liquidität über internationale Bankkonzerne sichergestellt, welche Überweisungen für den Hauptsitz auf das lokale Bankkonto durchführen. In dieser Studie wird analysiert, inwiefern Kryptowährungen eine valable Alternative wären, um den Cashflow solcher Niederlassungen schneller und günstiger sicher zu stellen (Krypto-Treasury). Die Autoren untersuchen hierbei konkret die für die Schweizer Exportindustrie wichtigsten Länder und die praktische Anwendbarkeit eines solchen kryptobasierten Überweisungsmechanismus. Um die grundsätzliche Machbarkeit des Krypto-Treasury-Ansatzes zu analysieren, werden in einem ersten Schritt die gesetzlichen Grundlagen in den jeweiligen Ländern genauer betrachtet. Hierbei ergab die Analyse ausserhalb der Region China/Hong Kong keine Hindernisse. Auch bezüglich der Auflagen (AML/ CTF/ KYC) zeigten sich insofern keine Schwierigkeiten, dass diese Auflagen in traditionellen Bankgeschäften bereits eingehalten werden müssen. Es bestehen diesbezüglich keine anderslautenden Auflagen für Kryptowährungen. Der Auswahl einer geeigneten Konvertierungsstelle und den damit einhergehenden Gebühren wird innerhalb der Studie ein hohes Gewicht verliehen, da davon sowohl der Prozess als auch die Kosten abhängen. Um einen effizienten Krypto-Treasury-Betrieb zu ermöglichen, müssen die Prozesse möglichst automatisiert werden. Gemäss Untersuchung ist dies bereits bei den meisten Konvertierungsstellen gewährleistet. Weiter muss beachtet werden, dass mit der Einführung eines KryptoTreasurys auch signifikante prozessuale Veränderungen stattfinden. Die Grundvoraussetzungen für ein Krypto-Treasury konnten durch diese konzeptionelle Studie bestätigt werden. Es bedarf jedoch weiterer Untersuchungen, um deren Anwendbarkeit in der Praxis zu prüfen
The Crown Trial and Athenian Legal Procedure in Public Cases against Illegal Decrees

description: This essay discusses several aspects of the legal procedures relating to Aeschines’ prosecution of Ctesiphon in 330 BCE. First, the essay demonstrates that through an improved reading of the law at Demosthenes 23.92 that Ctesiphon’s proposal had not expired when Aeschines brought his case to court in 330. Second, the essay shows that the penalty Aeschines would have suffered for not gaining one fifth of the votes at the trial was not the loss of the right to bring the same kind of cases again but the loss of the right to bring any public cases in the future. Third, the essays analyzes the phrase ‘trials brought by decree’ (Aeschin. 3.4) and proves that the phrase refers to trials in the Assembly brought on the basis of an ad hoc decree and not to trials in the courts with procedures modified by a decree of the Assembly.

description: In this paper, we first extend the celebrated PageRank modification to a higher-order Markov chain. Although this system has attractive theoretical properties, it is computationally intractable for many interesting problems. We next study a computationally tractable approximation to the higher-order PageRank vector that involves a system of polynomial equations called multilinear PageRank, which is a type of tensor PageRank vector. It is motivated by a novel "spacey random surfer" model, where the surfer remembers bits and pieces of history and is influenced by this information. The underlying stochastic process is an instance of a vertex-reinforced random walk. We develop convergence theory for a simple fixed-point method, a shifted fixed-point method, and a Newton iteration in a particular parameter regime. In marked contrast to the case of the PageRank vector of a Markov chain where the solution is always unique and easy to compute, there are parameter regimes of multilinear PageRank where solutions are not unique and simple algorithms do not converge. We provide a repository of these non-convergent cases that we encountered through exhaustive enumeration and randomly sampling that we believe is useful for future study of the problem.

description: Arithmetical congruence monoids, which arise in non-unique factorization theory, are multiplicative monoids $M_{a,b}$ consisting of all positive integers $n$ satsfying $n \equiv a \bmod b$. In this paper, we examine the asymptotic behavior of the set of irreducible elements of $M_{a,b}$, and characterize in terms of $a$ and $b$ when this set forms an eventually periodic sequence.

Background
The British Social Attitudes (BSA) survey series began in 1983. The series is designed to produce annual measures of attitudinal movements to complement large-scale government surveys that deal largely with facts and behaviour patterns, and the data on party political attitudes produced by opinion polls. One of the BSA's main purposes is to allow the monitoring of patterns of continuity and change, and the examination of the relative rates at which attitudes, in respect of a range of social issues, change over time. Some questions are asked regularly, others less often. Funding for BSA comes from a number of sources (including government departments, the Economic and Social Research Council and other research foundations), but the final responsibility for the coverage and wording of the annual questionnaires rests with NatCen Social Research (formerly Social and Community Planning Research). The BSA has been conducted every year since 1983, except in 1988 and 1992 when core funding was devoted to the British Election Study (BES).

description: We present first results on the calculation of fermionic spectral functions from analytically continued flow equations within the functional renormalization group approach. Our method is based on the same analytic continuation from imaginary to real frequencies that was developed and used previously for bosonic spectral functions. In order to demonstrate the applicability of the method also for fermionic correlations we apply it here to the real-time quark propagator in the quark-meson model and calculate the corresponding quark spectral functions in the vacuum.
title: Decision process of technology early adopters, impact of utility function and opportunity cost
Creators: name: Μωραϊτης Νικολαος
Publisher: name: Technical University of Crete
Year: 2024

description: With the increase in technology offering as services or technological devices, consumers respond to new products at various waves in the product life cycle. The key interest in such a new product is meeting a specific acceptance by the early adopters allowing it to become viable in the early stages of the product life cycle. As the acceptance by the early adopters’ segment of the market is related in achieving the products launch allowing it to secure the initial market penetration viability threshold, identifying decision making patterns and rationales in early adopters will provide information that can be utilized to meet consumer expectation in future technology products. The suggested methodology to tackle the above is using a structured questioner that aims to (a) identify someone as an early adopter, (b) to also rank the subjective utility function of the consumer on each product, (c) to also rank the subjective opportunity cost against similar products. Following the above rationale, a consumer successfully identified as early adopter will potentially denote one of the following (i) utility function and opportunity cost are aligned thus the decision-making criteria was correct, (ii) utility function and opportunity cost are not aligned thus the decision-making criteria was false. The above methodology aims to only demonstrate by cross examining utility-function and opportunity cost the decision-making process of early adapters and provide optimization insights on rational choice theory for the specific target group.
Left-left squark mixing in $K^+\rightarrowπ^+ν\barν$ and minimal SUSY

description: We analyze the role of the left-left squark mixing in the rare $K^+ \rightarrow π^+ν\barν$ decay within the minimal supersymmetry with a large $\tanβ$. A Higgs boson mass of 125 GeV has been taken into account leading to correlation between stop masses and trilinear soft supersymmetry breaking coupling $A_{\tilde{t}}$. We find that measurable effects, similar to that of the well known $LR$ squark mixing terms, are possible for large $A_{\tilde{t}}$ combined with the off-diagonal $LL$-insertions. Precise measurements of the decay rate are expected from the ongoing NA62 experiment at CERN. We emphasize that the effect we present can put certain limits on the left-left flavor changing structure of the squark mass matrix.

description: Schüler_innen mit Autismus besuchen oft integrativ die Regelschule. Im Unterricht werden auch Lehrund Lernformen mit vielen individuellen Lernangeboten angewendet. Diese erfordern von den Schüler_innen immer mehr selbstgesteuertes Lernen. Nicht alle Kinder bringen die Voraussetzungen mit, um bei offenen Aufgaben und Arbeitsformen zu lernen. Um die Aufmerksamkeit zu steuern, Aufgaben zu beginnen und zu beenden und Handlungsabläufe zu planen sind exekutive Funktionen erforderlich. Schüler_innen mit Autismus sind in den exekutiven Funktionen eingeschränkt und benötigen Unterstützung im Schulalltag. Der Inhalt dieser Arbeit fokussiert sich auf die Förderung der exekutiven Funktionen bei ihnen. Wie diese gestaltet ist, wurde in sechs Leitfadeninterviews mit Schulischen Heilpädagoginnen untersucht, die ein Kind mit Autismus in der integrativen Sonderschule im Zyklus 1 begleiten und fördern. Die Ergebnisse zeigten, dass durch die Förderung im Bereich der exekutiven Funktionen Fortschritte in der Flexibilität, der Impulskontrolle und der Selbständigkeit erzielt wurden.

description: Das vorliegende Working Paper geht auf den Zusammenhang zwischen interner Kommunikation, Mitarbeiterengagement und dem Aufkommen von internen sozialen Medien ein. Die interne Kommunikation ist heute ein anerkanntes Mittel, um den Unternehmenserfolg zu steigern. War bisher die Mitarbeiterzufriedenheit der Gradmesser für eine wirkungsvolle interne Kommunikation, so rückt der Begriff des Mitarbeiterengagements mehr und mehr in den Vordergrund. Engagierte Mitarbeitende sind aktiver, begeisterungsfähig und haben im Idealfall einen positiven Einfluss auf die Weiterempfehlungsbereitschaft des Arbeitgebers oder auf die Kundenzufriedenheit. Unabhängig voneinander haben unterschiedliche Studien in den letzten Jahren nachgewiesen, dass interne, unternehmensweite soziale Medien auf dem Vormarsch sind und das Potenzial haben, das Mitarbeiterengagement positiv zu beeinflussen. Als integrierter Bestandteil der internen Kommunikation haben sie gegenüber den althergebrachten Intranets grosse Vorteile, vor allem aufgrund ihrer multimedialen Funktionen und der Möglichkeiten der besseren Vernetzung und des Wissensaustausches – Faktoren, die für das Zugehörigkeitsgefühl zum Unternehmen und das Mitarbeiterengagement förderlich sind. Diese Ergebnisse wurden durch eine Online-Befragung von 157 Beschäftigten im Rahmen einer Bachelor Thesis der HWZ bestätigt. Die Nutzung eines sozialen Mediums korreliert darin positiv mit der Identifizierung mit dem Unternehmen und der Bereitschaft, sich für dieses zu engagieren. Unternehmen sind gut beraten, solche Plattformen in Ergänzung oder Ablösung zu bestehenden Intranets einzuführen. Dabei ist der Befähigung der Mitarbeitenden und der Vorbildfunktion des Managements grosse Aufmerksamkeit zu schenken, um die wertvolle betriebswirtschaftliche Ressource des Mitarbeiterengagements voll ausschöpfen zu können.

description: Study on the effects of various particulate reinforcements on the corrosion resistance of aluminum alloy (AA2618) matrix composites in different environments has been carried out. Metallic permanent molds were used to cast specimens in which 0vol%, 5vol%, 10vol%, 15vol%, 20vol%, 25vol% and 30vol% each of AA2618/SiC, AA2618/TiC and AA2618/fly ash composites were made. The cast specimens were machined to different dimensions for gravimetric and potentiostatic corrosion rate tests in one mole hydrochloric (1MHCl), sodium hydroxide (1MNaOH) and sea water environments where these composite specimens are normally exposed while in service. The results of the tests show that corrosion penetration rates of both gravimetric and potentiostatic of the composite samples increased along with increase in the vol% addition of these particles in the matrix of the alloy in these environments. The reason for this is that these particles promote localized corrosion within the matrix of the alloy by acting as anodic sites. The presence of these particles in the matrix of the alloy also helped in the infringements of dislocation movements in the matrices of the composites which are associated with particle clusters that generate high stress triaxiality in such regions. The increase in dislocation density resulted in high stress levels within the composites and this phenomenon caused high corrosion susceptibility as the percentages of these particles increased in the matrix of the alloy. AA2618/SiC immersed in NaOH environment recorded severe corrosion attack while least corrosion attack was recorded on composites immersed in sea water environment.

description: Sonderpädagogische Massnahmen bestehen aus einfachen und verstärkten Massnahmen. Im Kanton St. Gallen lassen sich die verstärkten Massnahmen aufgrund der Statistik der Lernenden darstellen. Dabei sind die Förder-, die Segregations- und die Separationsquote von Interesse. Sie werden im Vergleich zum nationalen und kantonalen Durchschnitt dargestellt. Für die einfachen Massnahmen fehlt diese Möglichkeit, weil die Erhebung durch die Schulleitungen von Seiten des BFS fakultativ ist und im Kanton St. Gallen nicht erhoben wird. Auf der Basis von 4 Antworten von 81 online befragten Schulverwaltungen, 12 Antworten von 87 online befragten Schulleitungen und 8 Antworten von 19 online befragten Lehrkräften wird versucht diese Lücke zu schliessen. Es zeigt sich, dass der Kanton St. Gallen bei allen Kennzahlen über dem nationalen Durchschnitt liegt. Aufgrund des geringen Rücklaufs der online Befragung kann ein Gesamtbild der einfachen sonderpädagogischen Massnahmen für den Kanton St. Gallen nicht gegeben werden. Die einfachen Massnahmen können aber für drei Gemeinden beschrieben werden.

description: LAMOST (Large Sky Area Multi-Object Fiber Spectroscopic Telescope) has completed the observation of nearly 20 million celestial objects, including a class of spectra labeled `Unknown'. Besides low signal-to-noise ratio, these spectra often show some anomalous features that do not work well with current templates. In this paper, a total of 638,000 `Unknown' spectra from LAMOST DR5 are selected, and an unsupervised-based analytical framework of `Unknown' spectra named SA-Frame (Spectra Analysis-Frame) is provided to explore their origins from different perspectives. The SA-Frame is composed of three parts: NAPC-Spec clustering, characterization and origin analysis. First, NAPC-Spec(Nonparametric density clustering algorithm for spectra) characterizes different features in the "unknown" spectrum by adjusting the influence space and divergence distance to minimize the effects of noise and high dimensionality, resulting in 13 types. Second, characteristic extraction and representation of clustering results are carried out based on spectral lines and continuum, where these 13 types are characterized as regular spectra with low S/Ns, splicing problems, suspected galactic emission signals, contamination from city light and un-gregarious type respectively. Third, a preliminary analysis of their origins is made from the characteristics of the observational targets, contamination from the sky, and the working status of the instruments. These results would be valuable for improving the overall data quality of large-scale spectral surveys.

description: Aluminum and their alloys, after careful treatments, can develop excellent mechanical, tribological, electrical and chemical (high corrosion resistance) properties. However, 7000 series, with Cu in the alloy, have a poor corrosion resistance. On the other hand, aluminum nitride (AlN) has a wurtzitic phase and good thermal stability, optical, electric, piezoelectric, mechanical, tribological, and chemical properties, so the application range is huge. In this paper, AlN deposition on Al 7075 was done using the reactive magnetron sputtering technique in order to verify the aluminum nitride performance as an Al alloy protective film under wear and corrosive processes.

description: Getrieben durch die Digitalisierung, agile Organisationsformen und den demographischen Wandel verändert sich auch die interne CEO-Kommunikation. Die Anzahl der Kommunikationsinstrumente nimmt zu und die Komplexität der Kommunikation hat sich erhöht. In dieser Studie untersuchen wir, wie sich die Kommunikation zwischen Geschäftsführenden („CEOs“) gegenüber den Mitarbeitenden verändert hat und sich heute sowie künftig darstellt. Auf Basis von Theorie und einem Fokusgruppengespräch werden zwei Thesen gebildet; die erste lautet: «Die Hauptfunktion der internen CEO-Kommunikation ist und wird auch künftig die Kommunikation der Strategie sein, wobei die Kommunikation von Werten künftig an Wichtigkeit gewinnen wird». Die zweite These lautet: «Die interne CEO-Kommunikation ist dazu da, Vertrauen zu schaffen (a). Im Zusammenhang mit dem Vertrauensgewinn spielt Transparenz eine wichtige Rolle (b)». Die Thesen und Instrumente wurden operationalisiert und als Items in einen Fragebogen mit geschlossenen Antwortmöglichkeiten auf eine Likert-Skala überführt. Der Fragebogen wurde an leitende Kommunikationsexperten der 120 mitarbeiterstärksten Unternehmen in der Schweiz versandt. 67 von ihnen haben den Fragebogen vollständig ausgefüllt. Die Ergebnisse zeigen u.a., dass aufgrund der Wahrnehmung der Antwortenden Strategie und Werte heute und in Zukunft wichtig bleiben, wobei die Werte die Strategie an Wichtigkeit nicht überholen. Das Gewinnen des Vertrauens ist eine zentrale Funktion der CEO-Kommunikation und Transparenz spielt dabei gemäss den Umfrageteilnehmenden in Zukunft eine noch gewichtigere Rolle. In diesen Zusammenhängen gibt die Umfrage indes auch Überraschendes preis, insbesondere dass die Befragten trotz der angenommenen, künftig noch wichtigeren Rolle der Transparenz von deren tatsächlichen Umsetzung weniger überzeugt sind. Ebenfalls überrascht, dass Onlineinstrumente weniger benutzt werden, als erwartet.

description: This article proves that an irreducible subfactor planar algebra with a distributive biprojection lattice admits a minimal 2-box projection generating the identity biprojection. It is a generalization (conjectured in 2013) of a theorem of Oystein Ore on distributive intervals of finite groups (1938), and a corollary of a natural subfactor extension of a conjecture of Kenneth S. Brown in algebraic combinatorics (2000). We deduce a link between combinatorics and representations in finite group theory.

Shapes and speeds of forced premixed flames
Creators: name: Joulin, Guy
name: Denet, Bruno
Publisher: name: arXiv
Year: 2014
Subjects: subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: Steady premixed flames subjected to space-periodic steady forcing are studied via inhomogeneous Michelson-Sivashinsky (MS) and then Burgers equations. For both, the flame slope is posited to comprise contributions from complex poles to locate, and from a base-slope profile chosen in three classes (pairs of cotangents, single-sine functions or sums thereof). Base-slope-dependent equations for the pole locations, along with formal expressions for the wrinkling-induced flame-speed increment and the forcing function, are obtained on excluding movable singularities from the latter. Besides exact few-pole cases, integral equations that rule the pole-density for large wrinkles are solved analytically. Closed-form flame-slope and forcing-function profiles ensue, along with flame-speed increment vs forcing-intensity curves; numerical checks are provided. The Darrieus-Landau instability mechanism allows MS flame speeds to initially grow with forcing intensity much faster than those of identically forced Burgers fronts; only the fractional difference in speed increments slowly decays at intense forcing, which numerical (spectral) timewise integrations also confirm. Generalizations and open problems are evoked.

subject: product warrantee

description: This research sought to identify the parts of the legal system in the United States directly influence the lifespans and capacity for repair of manufactured consumer hardgoods. For this, we sorted through the network of statutes and regulations on the federal level and in the fifty states, noting unique characteristics of the US legal system from an international perspective. We also identified the actors that make US statutes and standards. Our secondary research reviewed the statutes, standards and correlated economic and legal literature, and our primary research surveyed lawyers who provide counsel to manufacturers that sell consumer products in the United States. That research revealed the longstanding acceptance of planned obsolescence in mainstream economic theory and a wellestablished range of product warranties. The work brought into focus the powerful role that product warranties take in US commerce that can be leveraged to support longer product lifespans and greater product repair. In the near-term, consumer-friendly state legislatures are the most probable part of the government that would create new regulations on product lifespans. More proactive antitrust enforcement could also reduce collusion between competing companies to lower product lifespans.

Background
The British Social Attitudes (BSA) survey series began in 1983. The series is designed to produce annual measures of attitudinal movements to complement large-scale government surveys that deal largely with facts and behaviour patterns, and the data on party political attitudes produced by opinion polls. One of the BSA's main purposes is to allow the monitoring of patterns of continuity and change, and the examination of the relative rates at which attitudes, in respect of a range of social issues, change over time. Some questions are asked regularly, others less often. Funding for BSA comes from a number of sources (including government departments, the Economic and Social Research Council and other research foundations), but the final responsibility for the coverage and wording of the annual questionnaires rests with NatCen Social Research (formerly Social and Community Planning Research). The BSA has been conducted every year since 1983, except in 1988 and 1992 when core funding was devoted to the British Election Study (BES).

Further information about the series and links to publications may be found on the NatCen Social Research British Social Attitudes webpage.
$2$-Graded Identities for the Tensor Square of the Grassmann Algebra
Creators: name: Silva, Diogo Diniz Pereira da Silva e
Publisher: name: arXiv

Subjects: subject: Rings and Algebras (math.RA)
subject: FOS: Mathematics

description: We consider the algebra $E\otimes E$ over an infinite field equipped with a $\mathbb{Z}_2$-grading where the canonical basis is homogeneous and prove that in various cases the graded identites are just the ordinary ones. If the grading is a non-canonical grading obtained as a quotient grading of the natural $\mathbb{Z}_2\times\mathbb{Z}_2$-grading we exhibit a basis for the graded identities.
Kommunikationsstrategien für Gemeinden im Zeitalter der Digitalisierung. Eine Synthese verschiedener Forschungsarbeiten an der HWZ Hochschule für Wirtschaft Zürich

description: Kommunikation von Gemeinden dient dem Dialog zwischen Verwaltung und Bevölkerung, der Vermittlung gemeindespezifischer Inhalte mit dem Ziel, sachgerechte Entscheide über kommunale Vorlagen zu ermöglichen, und der Motivation von Nachwuchsleuten für öffentliche Ämter. Gemeindekommunikation stellt daher ein wesentliches Element der direkten Demokratie dar. Seit einigen Jahren erreicht kein Medium mehr die Mehrheit der Bevölkerung. Gemeindeinformationen zudem stehen im Konkurrenzkampf mit Informationen verschiedenster Absender und müssen sich, um wahrgenommen zu werden, den Gewohnheiten der Bevölkerung anpassen, namentlich dem wachsenden Bedürfnis nach Veranschaulichung von Inhalten mit Bildern und Videos, die zu Geschichten verarbeitet werden im Rahmen des sogenannten Storytellings. Dabei sind besondere Anforderungen bezüglich Professionalität, Identifizierbarkeit des Absenders, Verständlichkeit für alle Zielgruppen und Unvoreingenommenheit zu erfüllen, denn Steuergelder dürfen weder für politische noch für kommerzielle Zwecke eingesetzt werden. Je kleiner eine Gemeinde, desto weniger Inhalte lassen sich aufgrund der Ressourcen systematisch über verschiedene Kanäle verbreiten. Für Schwerpunktthemen empfiehlt sich der Aufbau eines – internen oder externen – Kommunikationsmanagements, das Inhalte für verschiedene Kanäle konfiguriert. Vorbild ist dabei der Corporate Newsroom, ein Modell, das vor allem von Medienhäusern verwendet wird, das sich in pragmatisch angepasster Form auch für Gemeinden eignet. Jede kommunale Kommunikationsstrategie muss sich mit der Frage auseinandersetzen, wie im Fall eines Ausfalls der digitalen Systeme informiert werden kann. Kommunikatives Störungspotenzial liegt auch in der Verbreitung von Falschinformationen auf der Sachebene oder zur Verunglimpfung von Verantwortungsträgern. Auch diesbezüglich sind Abwehrstrategien gefragt. Erforderlich ist eine Strukturierung der Krisenkommunikation im Rahmen der gesamten Kommunikationsstrategie unter Berücksichtigung der Besonderheiten der jeweiligen Gemeinde. Unter den Social Media bietet sich Twitter als Kommunikationsinstrument der Gemeinde an, um kurzfristige Informationen – beispielsweise über einen Stromausfall – zu verbreiten, sowie das Online-Lexikon Wikipedia für Informationen, die über den Tag hinaus gelten. Defensiv sind die Social Media mit Blick auf Shitstorms und «Fake News» ebenso zu beachten wie die konventionellen Medien.
Gradient corrections to the exchange-correlation free energy

description: We develop the first order gradient correction to the exchange-correlation free energy of the homogeneous electron gas for use in finite temperature density functional calculations. Based on this we propose and implement a simple temperature dependent extension for functionals beyond the local density approximation. These finite temperature functionals show improvement over zero temperature functionals as compared to path integral Monte Carlo calculations for deuterium and perform without computational cost increase compared to zero temperature functionals and so should be used for finite temperature calculations.

description: We study quantum non-Markovianity in the early stage of the emission process of a two-level atom coupled to a semi-infinite waveguide, where the waveguide termination behaves as a perfect mirror. Specifically, we restrict to the analysis of the process for times shorter than twice the time delay t_d, where t_d is the duration of a round trip along the atom-mirror path. We show the emergence of a threshold in the parameters space separating the Markovian and non-Markovian regions.
