description: Based on 26,883 investment decisions, we examine the influence of social media marketing on crowd participation in equity crowdfunding. We distinguish between different types of informative and persuasive posts on Facebook and Twitter. Informative posts provide investors with information about the crowdfunding campaign; persuasive posts do not, but rather aim to directly influence an investor’s decision-making process. We find that both types of posts have a positive impact on the number of investments. However, persuasive posts also increase the amount of an investment if they contain a statement about the previous investment success of the campaign and signal the crowd that they are not investing alone.

description: The layer dependent structural, electronic and vibrational properties of SnS2 and SnSe2 are investigated using first-principles density functional theory (DFT). The in-plane lattice constants, interlayer distances and binding energies are found to be layer-independent. Bulk SnS2 and SnSe2 are both indirect band gap semiconductors with Eg = 2.18 eV and 1.07 eV, respectively. Few-layer and monolayer 2D systems also possess an indirect band gap, which is increased to 2.41 eV and 1.69 eV for single layers of SnS2 and SnSe2. The effective mass theory of 2D excitons, which takes into account the combined effect of the anisotropy, non-local 2D screening and layer-dependent 3D screening, predicts strong excitonic effects. The binding energy of indirect excitons in monolayer samples, Ex~0.9 eV, is substantially reduced to Ex = 0.14 eV in bulk SnS2 and Ex = 0.09 eV in bulk SnSe2. The layer-dependent Raman spectra display a strong decrease of intensities of the Raman active A1g mode upon decreasing the number of layers down to a monolayer, by a factor of 7 in the case of SnS2 and a factor of 20 in the case of SnSe2 which can be used to identify number of layers in a 2D sample.

description: Mass-loss rate is one of the most important stellar parameters. We aim to provide mass-loss rates as a function of subdwarf parameters and to apply the formula for individual subdwarfs, to predict the wind terminal velocities, to estimate the influence of the magnetic field and X-ray ionization on the stellar wind, and to study the interaction of subdwarf wind with mass loss from Be and cool companions. We used our kinetic equilibrium (NLTE) wind models with the radiative force determined from the radiative transfer equation in the comoving frame (CMF) to predict the wind structure of subluminous hot stars. Our models solve stationary hydrodynamical equations, that is the equation of continuity, equation of motion, and energy equation and predict basic wind parameters. We predicted the wind mass-loss rate as a function of stellar parameters, namely the stellar luminosity, effective temperature, and metallicity. The derived wind parameters (mass-loss rates and terminal velocities) agree with the values derived from the observations. The radiative force is not able to accelerate the homogeneous wind for stars with low effective temperatures and high surface gravities. We discussed the properties of winds of individual subdwarfs. The X-ray irradiation may inhibit the flow in binaries with compact components. In binaries with Be components, the winds interact with the disk of the Be star. Stellar winds exist in subluminous stars with low gravities or high effective temperatures. Despite their low mass-loss rates, they are detectable in the ultraviolet spectrum and cause X-ray emission. Subdwarf stars may lose a significant part of their mass during the evolution. The angular momentum loss in magnetic subdwarfs with wind may explain their low rotational velocities. Stellar winds are especially important in binaries, where they may be accreted on a compact or cool companion. (abridged)

description: Research on climate change impacts has so far largely focussed on the direct effects caused by changes in key climate parameters such as mean temperatures, levels of precipitation, likelihood of extreme weather events etc. The main changes in these factors are today well established and scientific projections for the coming decades widely accepted. Many of the predicted shifts and changes will have an impact on food production systems, in fisheries, forestry and agriculture including agro-pastoral systems. Yet, as discussed above, in the context of food security and with regard to the particular role of biological diversity, indirect and complex systemic links may be even more important in many cases.

Digitale Methoden

description: To date, the construction industry is one of the sectors of economy least affected by digitization. The increased use of Building Information Modeling (BIM) in design firms is now accelerating the digitization of the construction industry. This enables the increased use of other digital tools in the construction process, e.g. Augmented Reality (AR). New tools offer the opportunity to rethink existing processes and to examine them for innovation and efficiency potential. The authors see great potential in the construction process for AR technology. In the research project AR-AQ-Bau, they, therefore, carried out an application and requirement analysis for AR. In this article, some current and possible applications of AR in the construction industry as well as their requirements for AR hard-and software (e. g. due to special conditions on construction sites) are presented. Additionally, an outlook into the future is given. The application area of AR is extremely diverse. On the one hand, BIM can be transferred to the construction site, and acceptance and quality controls can be carried out. On the other hand, a remote expert system, trainings and support in the building authorities procedure are additional applications.

Dies ermöglicht den vermehrten Einsatz weiterer digitaler Tools im Bauprozess, zum Beispiel Augmented Reality (AR). Neue Tools bieten die Chance, die vorhandenen Prozesse neu zu überdenken und auf Innovations- und Effizienzpotenzial zu untersuchen. Die Autoren sehen für die Technologie AR großes Potenzial im Bauprozess. Im Forschungsprojekt AR-AQ-Bau führten sie daher eine Anwendungs- und Anforderungsanalyse für AR durch. In diesem Artikel werden einige derzeitige und mögliche Anwendungen von AR im Bauwesen sowie deren Anforderungen an AR-Hard- und Software (z. B. durch die Besonderheiten der Baustelle) dargestellt und ein Ausblick in die Zukunft gegeben. Der Anwendungsbereich von AR ist äußerst vielfältig. Einerseits kann BIM dadurch leichter auf die Baustelle übertragen und können Abnahmen und Qualitätskontrollen durchgeführt werden. Andererseits stellen ein Remote-Expert-System, Schulungen und die Unterstützung im Behördenverfahren weitere Einsatzmöglichkeiten dar.

description: We experimentally study the occurrence of spontaneous spinning (Quincke rotation) of an ellipsoid in a uniform DC electric field. For an ellipsoid suspended in an unbounded fluid, we find two stable states characterized by the orientation of the ellipsoid long axis relative to the applied electric field : spinless (parallel) and spinning (perpendicular). The phase diagram of ellipsoid behavior as a function of field strength and aspect ratio is in close agreement with the theory of Cebers et al. Phys. Rev .E 63:016301 (2000). We also investigated the dynamics of the ellipsoidal Quincke rotor resting on a planar surface with normal perpendicular to the field direction. We find novel behaviors, such as swinging (long axis oscillating around the applied field direction) and tumbling, due to the confinement.

description: Using the automation program GoSam, fully differential NLO corrections were obtained for the rare decay of the muon $μ\to eν\barνee$. This process is an important Standard Model background to searches of the Mu3e collaboration for lepton-flavour violation, as it becomes indistinguishable from the signal $μ\to 3e$ if the neutrinos carry little energy. With our NLO program we are able to compute the branching ratio as well as custom-tailored observables for the experiment. With minor modifications, related decays of the tau can also be computed.

Michel parameters for $τ$ decays $τ\rightarrow lν\barν~(l=e,~μ)$ in a general two Higgs doublet model with $μ-τ$ flavor violation

description: In a general two Higgs doublet model (2HDM), the anomaly of muon anomalous magnetic moment (muon g-2) can be explained by $μ-τ$ flavor violating Yukawa couplings, motivated by the recent CMS excess in Higgs boson decay $h\rightarrow μτ$. We study Michel parameters for $τ$ decays $τ\rightarrow l ν\barν~(l=e,~μ)$ in the 2HDM with the lepton flavor violation, and show that they can be sensitive to the flavor structure as well as the Lorentz and chiral structures of the model. We find that the correction to the Michel parameter $ξ_μ$ in $τ\rightarrow μν\barν$ is correlated to the contribution to the muon g-2, and it can be as large as $10^{-4}-10^{-2}$ in the parameter region where the $μ-τ$ flavor violating Yukawa couplings explain the muon g-2 anomaly. Therefore the precision measurement of the Michel parameter at the level of $10^{-4}-10^{-2}$ would significantly probe the interesting parameter space for the solution to the muon g-2 anomaly.

description: One of the key priorities of The European Strategy Forum on Research Infrastructures (ESFRI) is to build sustainable and FAIR (Findable, Accessible, Interoperable, Reusable) infrastructures. However, designing and building such infrastructures requires careful consideration of various factors, such as data interoperability, operational sustainability, and governance. This poster proposes ten simple rules, inspired by Ten Simple Rules for scientific research, for designing and building a research infrastructure drawing from existing initiatives particularly from experiences in preparation of DiSSCo (Distributed System of Scientific Collections) – a new research infrastructure that was in the ESFRI 2018 roadmap. While these rules are not comprehensive, they highlight a few essential traits that can be applied across different disciplines. For each rule, we highlight how within DiSSCo we accomplished the specific aspect.

description: A large observation programme was carried out to measure the radial velocities of the components of a selection of common proper motion (CPM) stars, in order to select the physical binaries. Eighty wide binaries (WBs) were detected, and 39 optical pairs were identified. Adding CPM stars with separations close enough to be almost certain they are physical, a "bias-controlled" sample of 116 wide binaries was obtained, and used to derive the distribution of separations from 100 to 30,000 au. The distribution obtained doesn't match the log-constant distribution, but is in agreement with the log-normal distribution. The spectroscopic binaries detected among the WB components were used to derive statistical informations about the multiple systems. The close binaries in WBs seem to be similar to those detected in other field stars. As for the WBs, they seem to obey the log-normal distribution of periods. The number of quadruple systems is in agreement with the "no correlation" hypothesis; this indicates that an environment conducive to the formation of WBs doesn't favor the formation of subsystems with periods shorter than 10 years.

description: Social learning can reduce the costs associated with trial-and-error learning. There is speculation that social learning could contribute to trap and bait avoidance in invasive species like the Common Brushtail Possum (Trichosurus vulpecula) – a marsupial for which social learning has not previously been investigated. In large outdoor pens, we presented wild-caught 'demonstrator' possums with puzzle devices containing an attractive food reward; 2 of 8 demonstrators accessed the reward the first night the puzzle was presented and another 3 succeeded on later nights. Meanwhile, 'observer' possums in adjacent pens watched the demonstrators for five nights and then were given the opportunity to solve the puzzle themselves; 15 of 15 succeeded on their first night (a highly significant improvement). This experiment thus provides strong evidence of social learning by common brushtail possums. Future research should investigate whether information about aversive stimuli (such as traps and toxic baits) can similarly be transmitted between possums by social learning; if so, this could have important implications for possum pest control.

description: Since the mid-1990s, the German Federal Government has been trying to implement the liberalization of waste management, against the resistance of municipalities. But instead of creating a new fitting regulative environment for the sector, the strong position of the municipal waste management has been decomposed by delayed regulation. As a by-product of this policy of uncontrolled deregulation, some important effects of the modernisation strategy which was enforced in the early 1990s by the same government, under pressure of the environmental movement, are contested again.

description: Coherent spaces spanned by a finite number of coherent states, are introduced. Their coherence properties are studied, using the Dirac contour representation. It is shown that the corresponding projectors resolve the identity, and that they transform into projectors of the same type, under displacement transformations, and also under time evolution. The set of these spaces, with the logical OR and AND operations is a distributive lattice, and with the logical XOR and AND operations is a Boolean ring (Stone\rq{}s formalism). Applications of this Boolean ring into classical CNOT gates with $n$-ary variables, and also quantum CNOT gates with coherent states, are discussed.

High Gluon Densities in Heavy Ions Collisions

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The early stages of heavy ion collisions are dominated by high density systems of gluons that carry each a small fraction $x$ of the momenta of the colliding nucleons. A distinguishing feature of such systems is the phenomenon of "saturation" which tames the expected growth of the gluon density as the energy of the collision increases. The onset of saturation occurs at a particular transverse momentum scale, the "saturation momentum", that emerges dynamically and that marks the onset of non-linear gluon interactions. At high energy, and for large nuclei, the saturation momentum is large compared to the typical hadronic scale, making high density gluons amenable to a description with weak coupling techniques. This paper reviews some of the challenges faced in the study of such dense systems of small $x$ gluons, and of the progress made in addressing them. The focus is on conceptual issues, and the presentation is both pedagogical, and critical. Examples where high gluon density could play a visible role in heavy ion collisions are briefly discussed at the end, for illustration purpose.

It is applicable to absolutely-analytic normed groups (which include complete metrizable topological groups), and via a Steinhaus-type Sum-set Theorem (also a consequence of the shift-compactness theorem) includes the classical Open Mapping Theorem (separable or otherwise).

description: Integrated Coastal Zone Management (ICZM) as a means of enhancing sustainability has been the topic of a model project promoted by the EU during the late 1990s. Meanwhile, all member states are urged by an EU recommendation to develop national ICZM strategies, based on a set of criteria derived from this model project. The most prominent rationale of the criteria is a request to reassess existing spatial planning procedures and routines, in order to make them more participative and to strengthen and diversify the role of civil society actors. However, before ICZM was promoted, many European countries had already developed more or less complex features to include a growing number of actors in various stages of spatial planning processes: In concept building, decision making, and implementation. As a consequence, the EU recommendations have not been unanimously appreciated. One of the main arguments against them claimed that already existing schemes and procedures (i) provide a wide array of participative elements, and that (ii) participation has thus been a core element of spatial planning, even before ICZM appeared on the scene. Against this background, our study evaluated the performance of the German spatial planning system, in terms of integrating and co-ordinating different stakes into planning procedures of large scale infrastructure projects in the German coastal zone. The mechanisms for ensuring participation were assessed as well. The research was part of the development of a German National Strategy for Integrated Coastal Zone Management, a reaction to the EU recommendation. Based on the assumption that the established German spatial planning and approval system fulfils a decisive role in environmental regulation, regional economic development and the co-ordination of sectoral policies, the connection between ICZM and spatial planning will be discussed, with reference to the theoretical discussion about sustainable governance. The study thus helps to understand the prerequisites for participative management, and the relation between formal and informal administrative, as well as political, processes in countries with highly developed administrations and tightly applied regulations for decision-making. To introduce sustainability-oriented governance concepts, such as ICZM, in countries like Germany requires the government to combine instruments of spatial planning with participatory forms of vision building, in order to create new governance arrangements.

description: Since philosophical turns such as the spatial turn etc., geography has been dealing more intensively with the subjective perception and construction of space. Video games, and especially the vast digital spaces therein, are developed by teams of programmers, developers, and designers who make creative spatial construction decisions based on different worldviews, experiences, values, and skills. These processes result in a specific intended spatial experience for players to traverse. However, these players also approach the games with certain worldviews, prior experiences, values, etc., and the question arises to what extent spatial experiences can be intentionally passed through and what consequences the perception has for the (young) players we address with geography instruction. Thus, there is undoubtedly communication between both sides about digital space in video games. Furthermore, the question arises what role the creation of digital spaces in the games plays for the experience, understanding and reception of real analog spaces as well as for the further competences of students like in the field of sustainability or decision reflections. Thus, it cannot be dismissed that an engagement with video games should play a role in the context of addressing the reflection of spatial perceptions and constructions in geography education. Yet, they are still largely underrepresented in studies of geography education. In the paper, results from the research project "Gaming & Geography" will be presented, which attempts to create further legitimizing foundations for the integration of video games as a medium in the didactic discourse of geography via various empirical methods and transfer services. Based on the research in the project, a model for a reflexive analysis of digital space in video games will also be presented, which should facilitate a didactic integration of video games in geographic education. The results of the study provide a significant contribution to take the medium of video games as a geographical medium more seriously and the study provides further establishment measures to use the presented model didactically, because they show that students actively engage in geographic contexts in games, they reflect and the experts encourage the necessity of the presented model.

In this work, we present the experimental and theoretical results on the effect of Al substitution in FeGa3, obtained by x-ray diffraction (XRD), temperature dependent resistance measurement, room temperature Mossbauer measurements and density functional theory based electronic structure calculations. It is observed that upto x = 0.178 in Fe(AlxGa1-x)3, which is the maximum range studied in this work, Al substitution reduces the lattice parameters 'a' and 'c' preserving the parent tetragonal P42/mnm crystal structure of FeGa3. The bandgap of Fe(AlxGa1-x)3 for x = 0.178 is reduced by ~ 24% as compared to FeGa3. Rietveld refinement of the XRD data shows that the Al atoms replace Ga atoms located at the 8j sites in FeGa3. A comparison of the trends of the lattice parameters and energy bandgap observed in the calculations and the experiments also confirms that Al primarily replaces the Ga atoms in the 8j site.

description: Using Fermat's two squares theorem and properties of cyclotomic polynomials, we prove assertions about when numbers of the form $a^{n}+1$ can be expressed as the sum of two integer squares. We prove that $a^n + 1$ is the sum of two squares for all $n \in \mathbb{N}$ if and only if $a$ is a perfect square. We also prove that for $a\equiv 0,1,2\pmod{4},$ if $a^{n} + 1$ is the sum of two squares, then $a^δ + 1$ is the sum of two squares for all $δ| n, \ δ>1$. Using Aurifeuillian factorization, we show that if $a$ is a prime and $a\equiv 1 \pmod{4}$, then there are either zero or infinitely many odd $n$ such that $a^n+1$ is the sum of two squares. When $a\equiv 3\pmod{4},$ we define $m$ to be the least positive integer such that $\frac{a+1}{m}$ is the sum of two squares, and prove that if $a^n+1$ is the sum of two squares for any odd integer $n,$ then $m | n$, and both $a^m+1$ and $\frac{n}{m}$ are sums of two squares.

description: We develop a novel approach to enable the full-wave simulation of stimulated Brillouin scattering and related phenomena in a frequency-domain, finite-element environment. The method uses transformation optics techniques to implement a time-harmonic coordinate transform that reconciles the different frames of reference used by electromagnetic and mechanical finite-element solvers. We show how this strategy can be successfully applied to bulk and guided systems, comparing the results with the predictions of established theory.

“Consumerist Predators”? Emerging lifestyles between McDonaldization and sustainability perspectives: the case of highly qualified employees (HQEs) in India

description: In industrializing countries new groups of consumers with remarkable purchasing power are emerging. Representing a “new middle class” they are seen as a carrier and promoter of a so-called “western way of life” beyond the OECD countries. They are presented as having a consumerist predator lifestyle which stands in conflict with the requirements for a sustainable future. Furthermore, they are imputed a profound lack of a sense of responsibility towards society. However, such a ‘civil society spirit’ is a core prerequisite for coping with the challenge of changing existing lifestyles to insure a more sustainable future. Based upon data from a survey this paper demonstrates that these assumptions are flawed and constitute a misleading perception of the so-called new middle class and their potential role as contributor to and even promoter of a more sustainable future in industrializing countries. The situation is contradictory: on one hand they are clearly the most relevant agents of spreading non-sustainable lifestyles, predominantly confined to the OECD countries in the past. On the other hand relevant parts of them do acknowledge social responsibilities beyond the traditional ambit of their families, and they also acknowledge responsibilities to contribute to a more sustainable future. Thus, comparing the middle class of industrializing countries to those of the (post)industrializing countries, the most interesting question is not whether sustainability is explicitly an issue or not. It seems far more interesting to ask: what are the specific profiles of attitudes and everyday practices of particular groups of the “new middle class” in particular countries, and are these conducive to a more sustainable future in terms of both social and ecological responsibility? In pursuit of this our case study focuses on HQEs in India.
Optical vortices discern attosecond time delay in electron emission from magnetic sublevels

description: Photoionization from energetically distinct electronic states may have a relative time delay of tens of attoseconds. Here we demonstrate that pulses of optical vortices allow measuring such attoseconds delays from magnetic sublevels, even from a spherically symmetric target. The difference in the time delay is substantial and exhibits a strong angular dependence. Furthermore, we find an atomic scale variation in the time delays depending on the target orbital position in the laser spot. The findings offer thus a qualitatively new way for a spatio-temporal sensing of the magnetic states from which the photoelectrons originate, with a spatial resolution way below the diffraction limit of the vortex beam. Our conclusions follow from analytical considerations based on symmetry, complemented and confirmed with full numerical simulations of the quantum dynamics.

Care-(Ethik) und das Ethos fürsorglicher Praxis (Literaturstudie)

subject: 360

description: Diese Arbeit setzt sich mit den anglo-amerikanischen Care-Konzepten auseinander. Sie fällt in eine Zeit, in der die finanziellen Ressourcen im deutschen Gesundheitswesen knapper werden. Im Diskurs in deutschen Ethikkommissionen (die es vermehrt in Krankenhäusern gibt) wird vorrangig mit dem Prinzip der Autonomie argumentiert. Eine explizite Care-(Ethik) Debatte ist zwar in der Pflegewissenschaft erfolgt, jedoch hat die Pflegewissenschaft andere Schwerpunkte gesetzt, insbesondere die der Professionalisierung von Pflege, und wird im Bezugsrahmen der Pflegepraxis in Deutschland nicht rezipiert. Im Rahmen des Projektes „Die Bedeutung neuer Geschlechterverhältnisse für die Neue sozio-kulturelle Definition des Ethos fürsorglicher Praxis - am Beispiel Pflege“ versprechen wir uns von einer Beschäftigung mit den anglo-amerikanischen Care-Ansätzen Hinweise auf wichtige Elemente des Ethos fürsorglicher Praxis. Diese werden identifiziert; des weiteren wird überprüft, ob und wie sie in der deutschen Pflegepraxis zur Kenntnis genommen werden.

Quantum Speed Limit Bounds in an Open Quantum Evolution

description: Quantum mechanics dictates bounds for the minimal evolution time between predetermined initial and final states. Several of these Quantum Speed Limit (QSL) bounds were derived for non-unitary dynamics using different approaches. Here, we perform a systematic analysis of the most common QSL bounds in the damped Jaynes-Cummings model, covering the Markovian and non-Markovian regime. We show that only one of the analysed bounds cleaves to the essence of the QSL theory outlined in the pioneer works of Mandelstam \& Tamm and Margolus \& Levitin in the context of unitary evolutions. We also show that all of QSL bounds analysed reflect the fact that in our model non-Markovian effects speed up the quantum evolution. However, it is not possible to infer the Markovian or non-Markovian behaviour of the dynamics only analysing the QSL bounds.

description: While it might already seem unusual to turn attention first and foremost to the soundtrack in a study of documentary film, it probably seems even more unusual if the field of study is limited to the use of sound in historical (television) documentaries. But the situation threatens to become entirely absurd if we reduce the field even more and focus on the least prominent aspect of the soundtrack, noise.

description: We measured dispersive spin excitations in $\mathrm{SmFeAsO}$, parent compound of $\mathrm{SmFeAsO_{\text{1-x}}F_{\text{x}}}$ one of the highest temperature superconductors of Fe pnictides (T$_{\text{C}}\approx$55~K). We determine the magnetic excitations to disperse with a bandwidth energy of ca 170 meV at (0.47, 0) and (0.34, 0.34), which merges into the elastic line approaching the $Γ$ point. Comparing our results with other parent Fe pnictides, we show the importance of structural parameters for the magnetic excitation spectrum, with small modifications of the tetrahedron angles and As height strongly affecting the magnetism.
