description: Deep-water depositional systems are the ultimate sink for vast quantities of terrigenous sediment, organic carbon and anthropogenic pollutants, forming valuable archives of environmental change. Our understanding of the distribution of these particles and the preservation of environmental signals, in deep-water systems is limited due to the inaccessibility of modern systems, and the incomplete nature of ancient systems. Here, the deposit of a physically modelled turbidity current was sampled (n = 49) to determine how grain size and grain type vary spatially. The turbidity current had a sediment concentration of 17%. The sediment consisted of, by weight, 65% quartz sand (2.65 g/cm3), 17.5% silt (2.65 g/cm3), 7.5% clay (2.60 g/cm3) and 5% each of sand-grade garnet (3.90 g/cm3) and microplastic fragments (1.50 g/cm3). The grain size and composition of each sample was determined using laser diffraction and density separation, respectively. The results show that: (a) bulk grain size coarsened axially downstream on the basin floor challenging the notion that basin floor deposits fine radially from an apex upon becoming unconfined; (b) no sample composition matched the input composition of the flow, indicating that allogenic signals can be autogenically shredded and spatially variable in sediment gravity flow deposits; and (c) microplastic fragments were concentrated in levee and lateral basin floor fringe positions; however, microplastic concentrations in these positions were lower than input, suggesting microplastics bypassed the sampled positions. These findings have implications for: (a) the development of ‘finger-like’ geometries and facies distributions observed in modern and ancient systems; (b) interpreting environmental signals in the stratigraphic record; and (c) predicting the distribution of microplastics on the sea floor. © 2021 The Authors.

description: Against the orthodox view of the Nash equilibrium as “the embodiment of the idea that economic agents are rational” (Aumann, 1985, p 43), some theorists have proposed ‘non-classical’ concepts of rationality in games, arguing that rational agents should be capable of improving upon inefficient equilibrium outcomes. This paper considers some implications of these proposals for economic theory, by focusing on institutional design. I argue that revisionist concepts of rationality conflict with the constraint that institutions should be designed to be incentive-compatible, that is, that they should implement social goals in equilibrium. To resolve this conflict, proponents of revisionist concepts face a choice between three options: (1) reject incentive compatibility as a general constraint, (2) deny that individuals interacting through the designed institutions are rational, or (3) accept that their concepts do not cover institutional design. I critically discuss these options and I argue that a more inclusive concept of rationality, e.g. the one provided by Robert Sugden’s version of team reasoning, holds the most promise for the non-classical project, yielding a novel argument for incentive compatibility as a general constraint. © 2021, The Author(s).

description: We experimentally demonstrate a new dynamic fashion of quantum Zeno effect in nuclear magnetic resonance systems. The frequent measurements are implemented through quantum entanglement between the target qubit(s) and the measuring qubit, which dynamically results from the unitary evolution of duration $τ_{m}$ due to dispersive-coupling. Experimental results testify the presence of "the critical measurement time effect", that is, the quantum Zeno effect does not occur when $τ_{m}$ takes the some critical values, even if the measurements are frequent enough. Moreover, we provide a first experimental demonstration of an entanglement preservation mechanism based on such dynamic quantum Zeno effect.

description: Scientific reasoning (SR) skills and nature of science (NOS) beliefs represent important characteristics of biology teachers’ professional competence. In particular, teacher education at university is formative for the professionalization of future teachers and is thus the focus of the current study. Our study aimed to examine the development of SR skills and NOS beliefs and their mutual relationship during teacher education. We applied paper-and-pencil tests to measure SR skills and NOS beliefs of 299 preservice biology teachers from 25 universities in Germany. The results of linear mixed models and planned comparisons revealed that both SR skills and NOS beliefs develop over the course of the study. Nevertheless, the development of SR skills and multiple aspects of NOS beliefs proceeds in different trajectories. Cross-lagged models showed a complex picture concerning the mutual relationship between SR skills and NOS beliefs during their development (both positive and negative). The current study contributes to the existing research because it is based on longitudinal data and allows—in contrast to cross-sectional research—conclusions about the development of SR skills and NOS beliefs. © 2021 by the authors.

description: This paper investigates the incentives of a credit rating agency (CRA) to generate accurate ratings under an advertisement-based business model. To this end, we study a two-period endogenous reputation model in which a CRA can increase the precision of its ratings by exerting effort. The CRA receives a revenue not from rating fees, as is standard in the literature, but through online advertising. We show that the advertisement-based business model provides sufficient incentives for the CRA to improve the precision of signals at intermediate levels of reputation. Furthermore, we identify conditions under which truthful reporting is incentive compatible. © 2021, The Author(s).

description: Based on a dipolar-elastic model for oxygen vacancies on rutile (110), we evaluated analytically the overall energy of a periodic array of two vacancies and extracted the interaction parameters from total-energy density functional theory (DFT) calculations. Our calculations show that the dipole model holds for next-nearest neighbor vacancies and beyond. The elastic-dipolar interaction vanishes for adjacent vacancies, but they still experience an electrostatic repulsion. The proposed interaction model predicts a vacancy separation distribution that agrees well with that determined in our ultra-high vacuum scanning tunneling microscopy experiments, and provides a perspective for understanding earlier DFT reports.

description: We propose a new nonlinear Markov-STAR model to capture both the Markov switching and smooth transition dynamics for real exchange rates. We derive stationarity conditions for the model and apply it to the real exchange rates of 17 countries. We relate switching equilibrium rates and volatilities to a set of relevant macroeconomic variables and find, consistent with economic intuitions, that an economy deteriorating relative to the US economy tends to see a significantly increased likelihood of real exchange rate depreciation. Moreover, we document significant connections between rising economic uncertainties and real exchange rate changes as well as exchange rate volatility. © 2021 The Authors.

Wichtigste Trends auf dem Arbeitsmarkt sind die steigende Erwerbstätigkeit von Frauen und Älteren, die angemessene Integration von Migranten/innen, sowie die abnehmende Nachfrage nach einfacher Arbeit und eine wachsende gesellschaftliche Ungleichheit.
Durch die weitgehende Abschaffung oder Verteuerung der Vorruhestandsförderung und die Heraufsetzung der Altersgrenzen erhöhte sich bis 2011 die Erwerbstätigenquote Älterer um mehr als 20% auf 59,9% im Jahre 2011. Die weitreichenden Auswirkungen des Alterns ihrer Belegschaften haben viele Unternehmen aber in ihrer Personalpolitik
noch zu wenig im Blick.Wenn Frauen in Deutschland im gleichen Umfang wie in Schweden arbeiten könnten, stiege das Arbeitsangebot um rund 3,1 Millionen
Vollzeitangestellte. Kinderbetreuung und Ganztagsschulen werden hier allerdings im Vergleich zu Schweden erst mit rund 50 Jahren Verspätung ausgebaut. Für diese Angebote fehlt das Geld, weil in Deutschland zwei unterschiedliche Familienmodelle gefördert werden.Die Beschäftigung gering Qualifizierter wird zunehmend prekärer,
da die Unternehmen auf einfachen Tätigkeiten zunehmend nur noch Qualifizierte einsetzen. Eine Berufsausbildung wird zur Mindestbedingung,
um überhaupt Zugang zu einer Erwerbstätigkeit zu erhalten. Künftiger Fachkräftemangel kann nur durch verstärkte Anstrengungen in der Aus- und Weiterbildung vermieden werden.

description: Light scattering in disordered media has been studied extensively due to its prevalence in natural and artificial systems [1]. In the field of photonics most of the research has focused on understanding and mitigating the effects of scattering, which are often detrimental. For certain applications, however, intentionally introducing disorder can actually improve the device performance, e.g., in photovoltaics optical scattering improves the efficiency of light harvesting [2-5]. Here, we utilize multiple scattering in a random photonic structure to build a compact on-chip spectrometer. The probe signal diffuses through a scattering medium generating wavelength-dependent speckle patterns which can be used to recover the input spectrum after calibration. Multiple scattering increases the optical pathlength by folding the paths in a confined geometry, enhancing the spectral decorrelation of speckle patterns and thus increasing the spectral resolution. By designing and fabricating the spectrometer on a silicon wafer, we are able to efficiently channel the scattered light to the detectors, minimizing the reflection loss. We demonstrate spectral resolution of 0.75 nm at a wavelength of 1500 nm in a 25 μm by 50 μm random structure. Furthermore, the phenomenal control afforded by semiconductor nanofabrication technology enabled us to engineer the disorder to reduce the out-of-plane scattering loss. Such a compact, high-resolution spectrometer that is integrated on a silicon chip and robust against fabrication imperfections is well suited for lab-on-a-chip spectroscopy applications.

title: Je est un autre – Edička”. Autofiction e scrittura di sé in Eduard Limonov

Publisher: name: AvtobiografiЯ
Year: 2014

description: This article re-interprets Eduard Limonov’s first novel Eto ja – Edichka (1976) in the theoretical framework provided by recent studies on autobiography and namely drawing on the notion of autofiction. Focusing on the convoluted relationship between the author and his narrative persona Edichka with reference to literary devices such as abrupt shifts into third-person narration and disruption of chronological linearity, Limonov’s tendency to self-fictionalisation as a hero will be analysed. This creative strategy will paradoxically affect his best-known biographer, Emmanuel Carrère, who with Limonov (2011) will definitely assume the ongoing identification of the author with his hero as a matter of fact and provide the Western audience with a mere (yet well-written and highly enjoyable) retelling of Limonov’s novels.

description: Revenues from taxation gain in importance to finance economic development in Sub-Saharan Africa. One obstacle to enhancing the willingness to remit taxes can be the extortion of bribes by public officials. Using micro-level data from the Afrobarometer, we show that petty corruption erodes tax morale. The effect on tax morale is more severe in countries and regions where fewer people are affected by petty corruption and becomes insignificant if extortion of bribes is particularly prevalent. Differing levels of civic participation and potential access to tax funded services are also found to induce heterogeneous reactions to corruption experience. Applying a mediation analysis, we demonstrate that petty corruption not only has a direct effect on tax morale but also diminishes confidence in tax authorities and therefore affects tax morale indirectly. The harmful effects of corruption experience, however, operate mainly through a generally lowered inclination to uphold high levels of tax morale.

description: Ziel des vorliegenden Beitrags ist es, die alltägliche Praxis von Stadtplanerinnen und Stadtplanern zu reflektieren, um sich vertiefend mit Stadtplanung als Disziplin auseinanderzusetzen und herauszufinden, welche Implikationen damit für das berufliche Selbstverständnis von Planerinnen und Planern verbunden sind. Auf der Basis einer schriftlichen Befragung unter Planerinnen und Planern in den öffentlichen Verwaltungen deutscher Mittelstädte kann festgestellt werden, dass Stadtplanung zwar über spezifische inhaltliche Schwerpunkte und das dazugehörige Fachwissen verfügt, es Stadtplanung aber nicht gelingt, ihre gesellschaftliche Bedeutung glaubhaft zu vermitteln und die Identität der Planung herauszubilden. Stadtplanerinnen und Stadtplaner sorgen zwar für einen möglichst reibungslosen Ablauf der Verfahren und die Rechtssicherheit der Projekte, die Formalisierung der Bauleitplanung trägt aber gleichzeitig dazu bei, dass konzeptionelle Ansätze für eine verantwortungsbewusste Stadtentwicklung nur selten zu finden sind. Dies schlägt sich auch in den Selbst- und Rollenverständnissen von Planerinnen und Planern nieder, die sich eher als Projekt- und Prozessmanager und weniger als Innovatoren bzw. Impulsgeber sehen. Darüber hinaus ist der Berufsalltag durch interdisziplinäre Arbeitsweisen und Fachkenntnisse bestimmt, was ein weiteres unverwechselbares Merkmal von Stadtplanung darstellt. Die ausgeprägte Interdisziplinarität ist gleichzeitig aber auch die größte Schwäche von Stadtplanung, da die Vielzahl an Ansätzen, Wissensformen und Methoden dazu führt, dass es keinen eindeutig identifizierbaren Kern gibt. Eine Verständigung darüber scheint aber umso wichtiger, um den Planerinnen und Planern für ihr Handeln eine neue Orientierung zu geben, um (auch) zukünftig eine proaktive und strategische Koordination und Steuerung der Raumentwicklung im Sinne einer nachhaltigen Entwicklung zu gewährleisten.

description: We made a detailed study of the timing and spectral properties of the X-ray pulsar 1A 0535+262 during the recent giant outburst in 2020 November and December. The flux of the pulsar reached a record value of $\sim$12.5 Crab as observed by Swift/BAT (15--50 keV) and the corresponding mass accretion rate was $\sim6.67\times10^{17}$ g s$^{-1}$ near the peak of the outburst. There was a transition from the subcritical to the supercritical accretion regime which allows exploring different properties of the source in the supercritical regime. A q-like feature was detected in the hardness-intensity diagram during the outburst. We observed high variability and strong energy dependence of pulse profiles during the outburst. Cyclotron Resonant Scattering Feature (CRSF) was detected at $\sim44$ keV from the NuSTAR energy spectrum in the subcritical regime and the corresponding magnetic field was $B\simeq4.9\times10^{12}$ G. The energy of the CRSF was shifted towards lower energy in the supercritical regime. The luminosity dependence of the CRSF was studied and during the supercritical regime, a negative correlation was observed between the line energy and luminosity. The critical luminosity was $\sim6\times10^{37}$ erg s$^{-1}$ above which a state transition occurred. A reversal of correlation between the photon index and luminosity was observed near the critical luminosity. The NuSTAR spectra can be described by a composite model with two continuum components, a blackbody emission, cut-off power law, and a discrete component to account for the iron emission line at 6.4 keV. An additional cyclotron absorption feature was included in the model.

description: The magnetocaloric effect of gadolinium formate, Gd(OOCH)3, is experimentally determined down to sub-Kelvin temperatures by direct and indirect methods. This 3D metal-organic framework material is characterized by a relatively compact crystal lattice of weakly interacting Gd3+ spin centers interconnected via light formate ligands, overall providing a remarkably large magnetic:non-magnetic elemental weight ratio. The resulting volumetric magnetic entropy change is decidedly superior in Gd(OOCH)3 than in the best known magnetic refrigerant materials for liquid-helium temperatures and low-moderate applied fields.

description: We classify singular Enriques surfaces in characteristic two supporting a rank nine configuration of smooth rational curves. They come in one-dimensional families defined over the prime field, paralleling the situation in other characteristics, but featuring novel aspects. Contracting the given rational curves, one can derive algebraic surfaces with isolated ADE-singularities and trivial canonical bundle whose Q`-cohomology equals that of a projective plane. Similar existence results are developed for classical Enriques surfaces. We also work out an application to integral models of Enriques surfaces (and K3 surfaces).

description: In this paper, the author presents a brief overview of Eduard Limonov’s (1943) and Emmanuel Carrère’s (1957) artistic productions, especially dealing with their approaches to the relationship between fiction and reality. Reading Limonov’s autobiographical works, Carrère re-creates his pseudo-biographical depictions, “portraying” and interpreting Edichka’s “forma povedeniia”, or manner of life. The introduction of an intrusive narrator works as a strategy to “wear the narcissistic mask”. Analysing Limonov’s autobiographical mode, it is possible to observe how Carrère elaborates a complementary narrative level to “narrate his own self”, following Edichka’s experience.

description: The impact of the edges and presence of dopants to the work function (WF) of graphene nanoribbons (GNR) and nanoflakes was studied by an ab initio approach. The strong dependence of the WF upon the GNR structure was found and a promising character for the field emission by the donor type impurities was observed. Basing on the predominant impact of the nanostructure edges to the emission properties, the small graphene flakes were investigated as a possible source for the electron emission. The obtained weak dependence of the low WF values of the graphene flakes on their size and shape allows to suggest that the pure carbon medium with high and uniform emission properties can be fabricated by today technology.

description: The do-it-yourself mentality is particularly widespread in the furniture sector. Homemade furniture is very popular. The individualisation of furniture can be observed in internet forums, such as the online platform Pinterest. These creative ideas of potential customers show a need for individualized sustainable pieces of furniture. The current production structures, however, do not allow individual production according to the end customer's specifications. In addition, information logistics faces a major challenge: making the creative ideas of end consumers available to producers in parametric form. Topics such as customer requirements in relation to sustainable production, material specifications, industrial property rights, fair production conditions and traceability are the focus of this data interchange. An open and innovative European furniture ecosystem must be created to connect all stakeholders in the production process. This is made possible by a platform that channels the creativity of consumers and makes it designable and producible through the professional skills of designers. This requires the involvement of manufacturing specialists who can produce personalised products through sustainable intelligent production technologies. An exchange of information must also take place securely and quickly in order to protect the personal rights of the sources of ideas. This is being developed in the EU research project INEDIT - Open Innovation Ecosystem for do-it-together process. By connecting many different stakeholders along the entire value creation process, a change towards efficient collaborative collaboration is achieved.

description: Stellungnahme zur öffentlichen Anhörung des Ausschusses für Arbeit und Soziales im Deutschen Bundestag am 22. Oktober 2012

• (a) zum Gesetzentwurf der Fraktionen der CDU/CSU und der FDP:
Entwurf eines Gesetzes zu Änderungen im Bereich der geringfügigen
Beschäftigung (BT-Drs. 17/10773)
• (b) zum Antrag der Abgeordneten Sabine Zimmermann, Jutta
Krellmann, Diana Golze, weiterer Abgeordneter und der Fraktion
DIE LINKE:
Minijobs mit sozialversicherungspflichtiger Arbeit gleichstellen
(BT-Drs. 17/7386)

Der Gesetzentwurf der Regierungsfraktion zielt auf eine Anhebung der
Geringfügigkeitsgrenze von 400 auf 450 Euro im Monat. Entsprechend
sollen sich die Grenzwerte für die sogenannte Midi-Zone auf 450 bis 850
Euro im Monat verschieben. Zugleich ist vorgesehen, bei der Rentenversicherungspflicht
der Beschäftigten zu einer sogenannten op-out Regelung
überzugehen: Es muss erklärt werden, aus dem Regelfall der Versicherungspflicht
aussteigen zu wollen, wenn abgewichen werden soll. Der Gesetzentwurf
der Fraktion DIE LINKE zielt hingegen auf die grundsätzliche
Abschaffung der geringfügigen Beschäftigung und der entsprechenden
sozialversicherungs- und steuerrechtlichen Regelungen.
Die Stellungnahme weist darauf hin, dass eine Reform der geringfügigen
Beschäftigung geboten ist, um die vielfältigen Probleme, die mit diesen
Arbeitsverhältnissen verbunden sind, zu bewältigen. Als notwendig wird
die Begrenzung der Minijobs angesehen und nicht deren Ausweitung.

description: As Industry 4.0 infrastructures are seen as highly evolutionary environment with volatile, and time-dependent workloads for analytical tasks, particularly the optimal dimensioning of IT hardware is a challenge for decision makers because the digital processing of these tasks can be decoupled from their physical place of origin. Flexible architecture models to allocate tasks efficiently with regard to multi-facet aspects and a predefined set of local systems and external cloud services have been proven in small example scenarios. This paper provides a benchmark of existing task realization strategies, composed of (1) task distribution and (2) task prioritization in a real-world scenario simulation. It identifies heuristics as superior strategies.

description: The study of hot plasma expansion in a magnetic field is of interest for many laboratory and astrophysical applications. In this paper, an exactly solvable analytical model is proposed for an expanding resistive plasma in an external magnetic field in the regime in which the magnetic field does not perturb the plasma motion. The model is based on a class of exact solutions for the purely radial expansion of the plasma in the absence of a magnetic field. This approximation permits the reduction of the electromagnetic problem to consideration of a diffusion equation for the magnetic field. Explicit solutions are derived for a resistive cylindrical plasma expanding into a uniform ambient magnetic field. Some numerical examples related to the laser-produced plasma experiments are presented.

Effect of uniaxially anisotropic Fermi surface on the quasiparticle scattering inside a vortex core in unconventional superconductors

description: We theoretically study the dependence of the quasiparticle (QP) scattering rate $\varGamma$ on the uniaxial anisotropy of a Fermi surface with changing the magnetic field angle $α_{\rm M}$. We consider the QP scattering due to the non-magnetic impurities inside a single vortex core. The field-angle dependence of the quasiparticle scattering rate $\varGamma(α_{\rm M})$ is sensitive to the sign-change of the pair potential. We show that with increasing the two dimensionality of the system, $\varGamma(α_{\rm M})$ reflects more clearly whether there is the sign-change in the pair potential.

description: Breitbandige Störer nah am Grenzwert für DC-Ladestationen größer 75 kVA nach IEC 61851-21-2 sind kritisch für die Power Line Communication. Aktuell sind die Grenzwerte der genannten Norm noch nicht verbindlich, weshalb die Störaussendung bereits verfügbarer Ladestationen meist höher ist und damit ein echtes Gefährdungspotential für die PLC vorhanden ist. Oftmals ist derzeit trotzdem eine fehlerfreie Funktion möglich, da auch die PSD der PLC höher ist als die vorgeschriebenen -75dBm/Hz. Die höhere PSD kann allerdings zu Verletzungen der Störaussendungsgrenzwerte auf Netzseite oder im Fahrzeug führen, gerade auch weil von der PLC nach der North American Tone Mask auch Bänder genutzt werden, die je nach Fahrzeughersteller zu geschützten Frequenzbereichen zählen. Die in den Analysen nicht betrachtete Überkopplung in der Ladestation und im Fahrzeug sowie mögliche Störaussendung des Fahrzeugs durch interne DC/DC-Wandler können die Verhältnisse noch weiter verschärfen. Zugleich können Mehrwertdienste über PLC, welche zwangsläufig die Datenrate erhöhen, die Störfestigkeit der Power Line Communication reduzieren. Bei der Auslegung von DC-Ladestationen sollten die Grenzwert nach IEC 61851-21-2 nicht mit voller Bandbreite ausgereizt werden und es sollte stets auf eine gute Entkopplung zwischen HV+/HV- und CP geachtet werden, auch im Fahrzeug.

description: Die Emissionen eines Elektrofahrzeugs wurden nach unterschiedlichen Prüfmethoden untersucht. Es zeigte sich, dass die Emissionen nach Industrienorm über das gesamte Spektrum mit ca. 20 dB höher sind. Es ist zu empfehlen, die Fahrzeuge aus mehreren Richtungen, und nicht nur die Fahrer- und Beifahrerseite zu prüfen, sowie in verschiedenen Antennenhöhen zu messen. Weiterhin wurde der Einfluss des Mess-Setups der KFZ-Norm untersucht, da es in vielen EMV-Messhallen notwendig ist, zusätzliche Messachsen zu verwenden. Es stellte sich heraus, dass die Abweichungen zur Referenzachse nicht gering sind. Um die Ursache dieser Abweichungen näher zu untersuchen, wurden Messungen mit definierten Antennen vorgenommen. Diesen Messergebnissen ist zu entnehmen, dass die Abweichungen durch die Verwendung anderer Messachsen über den gesamten Frequenzbereich hoch waren, so dass einige dieser Messaufbauten ungeeignet für die Störemissionsmessung sind. Abschließend wurden die leitungsgebundenen Störemissionen von dem Elektrofahrzeug untersucht. Neben der normkonformen Emissionsmessung in 10 cm Höhe über dem Boden wurden Messungen mit 40 cm Höhe und 80 cm Höhe durchgeführt. Es ist nur eine geringe Abweichung festzustellen.

description: In this thesis I present the results of photoassociation measurements in ensembles of atomic calcium over an intensity range of below 1 W/cm2 up to 600 W/cm2. The temperature of the atoms was reduced to 1 μK by laser and evaporative cooling. Afterwards the two most-weakly bound states in the excited molecular potentials that dissociate to the asymtote 3P1+1S0 have been investigated regarding the shape and absolute rate of the resonances. The investigation showed that the measured rates differ by more than an order of magnitude compared to theoretical calculations. The predictions are based on a scattering formalism by Bohn & Julienne and wave functions derived from coupled-channel calculations. The shape of the resonances, the width in particular, agrees well with the numerical calculations. Especially the power broadening at high intensity is reproduced by the experiment. Further the light shift introduced by the photoassociation laser has been measured which also differs from the predictions. In the further course of the thesis the numerical simulations were improved by considering additional influences like the exact dependence of the Franck-Condon density and the light shift of the photoassociation laser as a function of the collision energy. Additionally the modeling of the experimental setup with a special emphasis on the volume of the optical trap and thus the density of the atomic ensemble was improved and the influence of varying trap depth and photoassociation duration has been studied. Investigating possible explanations for the discrepancy of the measured rates compared to theory, I show that by a modification of the coupling parameter and the spontaneous decay rate of the molecular state the rates measured in the experiment can be reproduced theoretically, with the restriction that at high intensity the calculated line shape no longer agrees with the measurement. In the last chapter an improved experimental apparatus is presented that by using an optical lattice suppresses thermal broadening and thus simplifies the analysis substantially.
