Bayesian priors for the eccentricity of transiting planets

Year: 2014
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Planets on eccentric orbits have a higher geometric probability of transiting their host star. By application of Bayes' theorem, we reverse this logic to show that the eccentricity distribution of transiting planets is positively biased. Adopting the flexible Beta distribution as the underlying prior for eccentricity, we derive the marginalized transit probability as well as the a-priori joint probability distribution of eccentricity and argument of periastron, given that a planet is known to transit. These results allow to demonstrate that most planet occurrence rate calculations using Kepler data have overestimated the prevalence of planets by ~10%. Indeed, the true occurrence of planets from transit surveys is fundamentally intractable without a prior assumption for the eccentricity distribution. Further more, we show that previously extracted eccentricity distributions using Kepler data are positively biased. In cases where one wishes to impose an informative eccentricity prior, we provide a recursive algorithm to apply inverse transform sampling of our joint prior probability distribution. Computer code of this algorithm, ECCSAMPLES, is provided to enable the community to sample directly from the prior.

Prophylaktische und kurative Wirksamkeit
HWZ Working Paper Series

description: «Meditation» ist ein breit verwendeter Begriff, wird jedoch häufig als Privatangelegenheit verstanden und findet leider (noch) wenig Anerkennung im beruflichen Umfeld. Die Meditation, prophylaktisch oder als kurative Lebensphilosophie oder -hilfe verstanden, löst bei vielen Führungskräften Skepsis aus und ist vielfach mit Vorurteilen behaftet. Es ist vielerorts noch wenig bekannt, dass der Stresslevel im beruflichen Alltag durch Meditation reduziert werden kann, eine Verminderung grüblerischer Gedanken bewirkt und eine Zunahme von Selbstführung und Mitgefühl zeigt. Dies fördert letztlich eine bessere Distanz und Abgeklärtheit zu den Dingen, damit bessere Entscheide gefällt werden können, was die Potenzialentfaltung von Führungskräften nachhaltig beeinflusst. Eine Studie der HWZ Hochschule für Wirtschaft, welche auf der Bachelor Thesis von Gina Mehmann weiterentwickelt wurde, hat sich mit dem Thema Achtsamkeitsmeditation und ihrem Nutzen für Führungskräfte in Schweizer Unternehmen beschäftigt. Der vorliegende Artikel bestätigt weitgehend, dass die Achtsamkeitsmeditation die Führungsqualität eines Vorgesetzten und somit dessen berufliche Leistungsfähigkeit, unabhängig von Geschlecht und Alter, in Schweizer Unternehmen fördern kann. Geschlechtsspezifisch kann diese Annahme nicht verallgemeinert werden, ob diese «typischen» Eigenschaften von Männern und Frauen angeboren sind oder lediglich durch die Gesellschaft vorgegeben werden. Im Weiteren ist Achtsamkeit keine Privatsache, sondern eine Voraussetzung, um ein neues Führungsverständnis positiv zu entwickeln. Es ist deshalb sinnvoll, die Methoden der Achtsamkeit mit vergleichbaren Attributen wie Stressmanagement, Kreativitätssteigerung beziehungsweise mit guten Führungsqualitäten zu verbinden. Die zahlreichen jährlich veröffentlichten Artikel zu den Wirkungen von Meditation bestätigen das zunehmende Interesse in Forschung und Praxis.

description: We consider Lagrangians in 3+1 dimensions admitting topological defects where there is an additional coupling between the defect scalar field $Φ$ and the gauge field kinetic term (eg $B(\vert Φ\vert^2) F_{μν}F^{μν}$). Such a {\it dilatonic} coupling in the context of a static defect, induces a spatially dependent effective gauge charge and effective mass for the scalar field which leads to modified properties of the defect core. In particular, the scale of the core gets modified while the stability properties of the corresponding embedded defects are also affected. These modifications are illustrated for gauged (Nielsen-Olesen) vortices and for gauged ('t Hooft-Polyakov) monopoles. The corresponding dilatonic global defects are also studied in the presence of an external gauge field.

description: Dass Motivation im Verkauf eine wichtige Rolle spielt, ist nicht neu und es gibt auch eine ganze Menge an Konzepten dazu. Was bisher weitgehend vernachlässigt wurde, ist die Demotivation als Gegenstück zur Motivation. In diesem Beitrag werden die beiden Begriffe anhand der relevanten Theorien in Beziehung gesetzt zur Situation im Verkauf einer Unternehmung in der Schweiz. Daraus abgeleitet werden die Bedingungen und Erfolgsfaktoren für wirksame betriebliche Anreizsysteme erörtert: Transparenz, Individualität, Langfristigkeit, Kongruenz mit den Unternehmenszielen, Flexibilität, Leistungsorientierung und Wirtschaftlichkeit (Semar, 2004, S. 260). Im Zusammenhang mit diesen Erkenntnissen sind in einer Befragung von Verkäuferinnen und Verkäufern die bestehenden Motivationsbarrieren ermittelt und auf Handlungsbedarf analysiert worden. Die wichtigsten acht Motivationsbarrieren – Entscheidungsfreiheiten, Einfluss auf andere Personen, Zielklarheit und -erreichbarkeit, Feedback, Leistungsanerkennung, fixer/variabler Lohnanteil, bestehendes Weiterbildungsangebot und Arbeitsprozesse – wurden in einem weiteren Schritt dem bestehenden Anreizsystem gegenübergestellt. Aus dieser Synopse wiederum konnten konkrete Empfehlungen für die Weiterentwicklung des bestehenden Anreizsystems abgeleitet und in einem letzten Schritt mit Hilfe einer Nutzwertanalyse evaluiert werden. Die Kriterien dieser Evaluation waren Mitarbeitendenakzeptanz, Investitionskosten, Kostenminimierung und Umsetzungsdauer, was am Ende neben den inhaltlichen Empfehlungen auch zu einem Priorisierungsvorschlag geführt hat. Als Quintessenz dieser Untersuchung hat sich herausgestellt, dass gar nicht den monetären Faktoren die höchste Aufmerksamkeit geschenkt werden sollte, sondern eher den nichtmonetären. Eine Verbesserung der Arbeitsprozesse, um die Erledigung der täglichen Arbeiten zu erleichtern und damit gleichzeitig die Zielerreichung realistischer zu machen, hat sich als Nummer eins unter den vorgeschlagenen Massnahmen herausgestellt, gefolgt von der Empfehlung, in eine bessere Qualität der Mitarbeitendengespräche zu investieren.

description: We apply Zhang's almost Kähler Nakai-Moishezon theorem and Li-Zhang's comparison of $J$-symplectic cones to establish a stability result for the symplectomorphism group of a rational $4$-manifold $M$ with Euler number up to $12$. As a corollary, we also derive a stability result for the space of embedded symplectic balls in $M$. A noteworthy feature of our approach is that we systematically explore various spaces and groups associated to a symplectic cohomology class $u$ rather than with a single symplectic form $ω$. To this end, we prove a weaker version of the tamed $J$-inflation procedures of D. McDuff and O. Buse that fixes a gap in their original formulations.

description: L'Europa ospita il 12% della popolazione mondiale, produce il 22% del PIL mondiale, è la seconda potenza economica in termini nominali (dopo gli USA), primo importatore al mondo di energia e il primo fornitore di aiuti ai Paesi in via di sviluppo. È un gigante economico, ma anche un nano politico e un verme militare. Tale frase è attribuita a Henry Kissinger, forse rivolta all'Europa, o forse alla Germania - la cui interscambiabilità desta timori reconditi. La strutturazione di un'identità europea si inquadra in un percorso intrapreso dagli Stati membri a partire dal secondo dopoguerra. Gli equilibri internazionali e le fragilità interne motivarono l'investimento nell'attore comunitario, forse sopravvalutando la disponibilità all'identificazione di strategie condivise, in nome dell'interesse dei Paesi membri. L'odierna impasse in cui versa tale percorso rivela una fragilità originaria dell'Unione sul piano dell'identità storica e sociale. A tale riguardo, la sociologia ha fornito, in tempi non sospetti, alcune chiavi interpretative per la decodifica dei fenomeni di strutturazione e di disaggregazione dell'identità, in questo caso europea.
The spectroscopic challenges of sulfur
Creators: name: Lucertini, Francesca
Publisher: name: Zenodo
Year: 2023

description: Alpha-elements can be used as cosmic clocks to constrain both stellar nucleosynthesis and galaxy's formation history.
 Sulfur is the outcast alpha-element. Indeed, its analysis is often skipped in favor of the other alpha-elements, which are less complicated to measure. The challenges in question are the weakness of optical sulfur lines, the contamination due to telluric lines, and the deviation from local-thermodynamic equilibrium of near-infrared sulfur lines. Consequently, the behavior of sulfur has been mainly investigated in the solar neighborhood and a few stellar clusters.
 Being volatile, sulfur is the proxy of alpha-elements for high-redshift systems. In fact, its abundances measured in local stars and gaseous phase in the far Universe (as Damped Ly-alpha systems, DLA) can be directly compared. These kinds of studies are relevant to understand the formation and evolution of galaxies, since DLAs have been proposed as progenitors of dwarf galaxies (i.e. the Milky Way building blocks). However, the Sculptor dwarf galaxy is the only extragalactic system for which sulfur abundances have been measured in stellar atmospheres.
 This talk aims to show new outcomes on the sulfur behavior in the Milky Way major components. The results for 74 bulge stars, 21/30 thick/thin-disk stars and 24 halo stars observed with FLAMES/UVES@VLT will be presented. It will be shown that the chemical evolution of the Milky Way traced by sulfur provides clues on the formation of our Galaxy.

description: This paper presents a reversible data hiding in encrypted image that employs based notions of the RDH in plain-image schemes including histogram modification and prediction-error computation. In the proposed method, original image may be encrypted by desire encryption algorithm. Most significant bit (MSB) of encrypted pixels are integrated to vacate room for embedding data bits. Integrated ones will be more resistant against failure of reconstruction if they are modified for embedding data bits. At the recipient, we employ chess-board predictor for lossless reconstruction of the original image by the aim of prediction-error analysis. Comparing to existent RDHEI algorithms, not only we propose a separable method to extract data bits, but also content-owner may attain a perfect reconstruction of the original image without having data hider key. Experimental results confirm that the proposed algorithm outperforms state of the art ones.
Black hole-like hysteresis and accretion states in neutron star low mass X-ray binaries

description: We have systematically studied a large sample of the neutron star low mass X-ray binaries (LMXBs) monitored by the Rossi X-ray Timing Explorer (50 sources; 10000+ observations). We find that the hysteresis patterns between Compton dominated and thermal dominated states, typically observed in black hole LMXBs, are also common in neutron star systems. These patterns, which also sample intermediate states, are found when looking at the evolution of both X-ray colour and fast variability of ten systems accreting below ~ 30 % of the Eddington Luminosity. We show that hysteresis does not require large changes in luminosity and it is the natural form that state transitions take at these luminosities. At higher accretion rates neutron stars do not show hysteresis, and they remain in a thermal dominated, low variability state, characterized by flaring behaviour and fast colour changes. Only at luminosities close to the Eddington Luminosity, are high variability levels seen again, in correspondence to an increase in the fractional contribution of the Comptonization component. We compare this behaviour with that observed in LMXBs harbouring black holes, showing that the spectral, timing and multi-wavelength properties of a given source can be determined by its location in the fast variability-luminosity diagram, which, therefore, provides a common framework for neutron star and black hole accretion states.

Year: 2023

description: This work proposes a novel distributed control framework in which a team of pursuer agents equipped with a radio jamming device cooperate in order to track and radio-jam a rogue target in 3D space, with the ultimate purpose of disrupting its communication and navigation circuitry. The target evolves in 3D space according to a stochastic dynamical model and it can appear and disappear from the surveillance area at random times. The pursuer agents cooperate in order to estimate the probability of target existence and its spatial density from a set of noisy measurements in the presence of clutter. Additionally, the proposed control framework allows a team of pursuer agents to optimally choose their radio transmission levels and their mobility control actions in order to ensure uninterrupted radio jamming to the target, as well as to avoid the jamming interference among the team of pursuer agents. Extensive simulation analysis of the system's performance validates the applicability of the proposed approach.

description: We consider a single impurity atom confined to an optical lattice and immersed in a homogeneous Bose-Einstein condensate (BEC). Interaction of the impurity with the phonon modes of the BEC leads to the formation of a stable quasiparticle, the polaron. We use a variational mean-field approach to study dispersion renormalization and derive equations describing non-equilibrium dynamics of polarons by projecting equations of motion into mean-field (MF) type wavefunctions. As a concrete example, we apply our method to study dynamics of impurity atoms in response to a suddenly applied force and explore the interplay of coherent Bloch oscillations and incoherent drift. We obtain a non-linear dependence of the drift velocity on the applied force, including a sub-Ohmic dependence for small forces for dimensionality d>1 of the BEC. For the case of heavy impurity atoms we derive a closed analytical expression for the drift velocity. Our results show considerable differences with the commonly used phenomenological Esaki-Tsu model.

description: A multi-dimensional switched system or multi-mode multi-dimensional ($M^3D$) system extends the classic switched system by allowing different subsystem dimensions. The stability problem of the $M^3D$ system, whose state transitions at switching instants can be discontinuous due to the dimension-varying feature, is studied. The discontinuous state transition is formulated by an affine map that captures both the dimension variations and the state impulses, with no extra constraint imposed. In the presence of unstable subsystems, the general criteria featuring a series of Lyapunov-like conditions for the practical and asymptotic stability properties of the $M^3D$ system are provided under the proposed slow/fast transition-dependent average dwell time framework. Then, by considering linear subsystems, we propose a class of parametric multiple Lyapunov functions to verify the obtained Lyapunov-like stability conditions and explicitly reveal a connection between the practical/asymptotic stability property and the non-vanishing/vanishing property of the impulsive effects in the state transition process. Further, the obtained stability results for the $M^3D$ system are applied to the consensus problem of the open multi-agent system (MAS), whose network topology can be switching and size-varying due to the migrations of agents. It shows that through a proper transformation, the seeking of the (practical) consensus performance of the open MAS with disconnected digraphs boils down to that of the (practical) stability property of an $M^3D$ system with unstable subsystems.

title: The British Cavalry 1920-1940
Creators: name: Evans, Gary
Publisher: name: University of Kent
Year: 2022

description: This thesis examines the British cavalry 1920-40. It investigates the issues facing the cavalry and General Staff during the period. To do this it takes several methodological approaches. Firstly, using War Office files and other primary sources it looks at the political, economic and doctrinal issues affecting the army and how these impacted upon the cavalry. The time frames for analysing these factors arc built around the creation of the DRC in 1934. This year saw a watershed when the likelihood of the cavalry being mechanised moved from being a possibility to a certainty. It shows that there were cavalrymen who supported modernisation but the General Staff were hampered in their efforts by politicians and, to a lesser extent, tank advocates themselves. An analysis of the Yeomanry cavalry is also undertaken which reveals that the General Staff at the beginning of this period tried to undertake a radical restructuring of its Territorial Force. The selfish outlook of amateur military men of social influence along with the political dalliances of Churchill forced the General Staff to virtually abandon its plans. This was to have repercussions upon mobilisation and beyond. The thesis utilises the large oral testimony held at the IWM, to investigate the cultural nature of the cavalry of this period. This reveals a service arm frequently lacking in professionalism; a source of enmity between services branches, in particular, the RTC, who mistook lack of focus for a resistance to change. Yet, longer-serving officers were committed to modernisation and it was the ‘bright young things’ of the 20s and 30s who were especially enamoured with the cult of the horse. Then, using 23, Cavalry Journal along with other primary records, an analysis is made of how the British cavalry saw itself in comparison to other nations’ mounted units. It shows how the cavalry and the General Staff believed that they were in advance of other nations in their perceptions on cavalry. However, by the late 1930s, this confidence was misplaced as the Germans, the French with their DLMs and the US cavalry began to overtake the British. The conclusions drawn show that the cavalry did not retard the mechanisation of the British army but it did not advance it either. The failings of mechanisation lay in factors often beyond the control of the army and for the cavalry’s part when it asked to mechanise it did so with far more zeal than it is given credit for.

description: Structure formation in the current Universe operates through the accretion of group-scale systems onto massive clusters. The detection and study of such accreting systems is crucial to understand the build-up of the most massive virialized structures we see today. We report the discovery with XMM-Newton of an irregular X-ray substructure in the outskirts of the massive galaxy cluster Abell 2142. The tip of the X-ray emission coincides with a concentration of galaxies. The bulk of the X-ray emission of this substructure appears to be lagging behind the galaxies and extends over a projected scale of at least 800 kpc. The temperature of the gas in this region is 1.4 keV, which is a factor of ~4 lower than the surrounding medium and is typical of the virialized plasma of a galaxy group with a mass of a few 10^13M_sun. For this reason, we interpret this structure as a galaxy group in the process of being accreted onto the main dark-matter halo. The X-ray structure trailing behind the group is due to gas stripped from its original dark-matter halo as it moves through the intracluster medium (ICM). This is the longest X-ray trail reported to date. For an infall velocity of ~1,200 km s-1 we estimate that the stripped gas has been surviving in the presence of the hot ICM for at least 600 Myr, which exceeds the Spitzer conduction timescale in the medium by a factor of >~400. Such a strong suppression of conductivity is likely related to a tangled magnetic field with small coherence length and to plasma microinstabilities. The long survival time of the low-entropy intragroup medium suggests that the infalling material can eventually settle within the core of the main cluster.

From rereading to invention: the role of the text produced so far in the genesis of literary texts

description: Writers spend a lot of time rereading their own texts (Wengelin et al. 2023; Quinlan et al. 2013). Rereading plays an important role in the revision process. Or as Bryant puts it: “Revision is the writer-as-reader’s rewriting” (Bryant 2002, 98). Hayes’ (2012) model of the writing process categorises the different cognitive functions at work in a writing process and the (external) text produced so far (TPSF) is, in this model, controlled by the internal transcriber. However, Lindgren et al. (2019) state that there are dynamic ways in which the TPSF can feed into the internal writing process. Evaluating and revising of the TPSF are not the only processes associated with rereading. Writers namely also tend to ‘look back’ at previously written text in order to generate new text (Breetvelt et al. 1994; Wengelin et al. 2023). In this way, the TPSF functions as “a catalyst for invention” (Leijten et al. 2014, 325). This brings us to the focus of genetic criticism, which Ferrer defines as the science of written invention (2011).

This paper explores the role of the TPSF in the genesis of literary texts. The keystroke data collected from literary writers using the keystroke logger Inputlog (Leijten & Van Waes 2013) allows us to examine how the TPSF guides new text production in literary writing. Unlike analogue versions of a text, keystroke-based reconstructions of the writing process allow us to analyse the text at any point in the writing process. While this does not allow us to study ‘lookbacks’ that have not left a textual trace, as would be possible with eyetracking (Wengelin et al. 2023), we can still observe the state of the text, for example, as new ideas emerge, or as ideas about the text or specific formulations change direction. Within genetic criticism, this allows us to hypothesise about how certain formulations in the TPSF have led to revisions or the insertion of new aspects into the text. In this paper I will discuss several examples that provide insight into how, in literary writing, the text emerges through a constant engagement with what has already been written.

description: Studies on microplastics in soils is currently being established as a new research field. So far, mainly 'explorative studies' have been carried out to detect microplastics in different soil environments. To generate a deeper understanding of microplastics dynamics, 'systematic studies' are required. Such research must built on a targeted sampling strategy and considerate fieldwork and sample handling. From literature enquiry, a five-stage methodological workflow was deduced for studies on microplastics in soils. In the present review, the spatial representation of soils/soilscapes with microplasticsin soils research is conceptually and practically assessed. We discuss judgmental, randomized, and metric soil sampling strategies. Then, we explain sample pre-processing and give a brief overview of methods for microplastics identification and quantification. We conclude that the establishment of the novel field of research 'microplasticdynamics in soils' requires more intensive consideration of soil sampling strategies. Assoil is a complex medium and the soilscape is spatially heterogeneous, we highlight systematic sampling strategies as the best possible options for sophisticated research. However, no overall optimum methodology can be defined because the specific strategy must be in line with the particular research question. For all studies on microplastics in soils, practical improvement is needed to prevent contamination of soilsamples with plastics during sampling and sample pre-processing.

description: In dieser explorativen Studie wird anhand fünf deutscher Grosskonzerne untersucht, welche Mobilitätsangebote für Reisetätigkeiten bestehen und wie diese, eingebettet in eine HR-Strategie, gezielt zur Mitarbeiterbindung genutzt werden. Drei Reisezwecke werden untersucht: (1) Das Pendeln zwischen Wohn- und Arbeitsort, (2) Geschäftsreisen, um geschäftliche Aufgaben ausserhalb des Arbeitsortes auszuüben und (3) nicht geschäftsbezogene Reisen in der Freizeit der Mitarbeitenden. Flugreisen werden in dieser Studie nicht berücksichtigt. In Anknüpfung an den demographischen (Werte-)Wandel und die erhöhte Mobilität wird in diesem Arbeitspaper insbesondere der Wunsch der Mitarbeitenden nach individueller Gestaltung von Mobilität in den Mittelpunkt gestellt: Die neuen Lebensweisen führen zu neuen Mobilitätsstilen sowohl während der Arbeits- als auch während der Freizeit und somit zu einem breiteren Bedürfnis an Mobilitätsalternativen – Multimodalität in der Mobilität ist gefragt. Der Arbeitgeber ist hervorragend positioniert, um Multimodalmobilität für sämtliche Reisezwecke der Mitarbeitenden einzuführen: Das Unternehmen bietet eine Vernetzung – eine reale Vernetzung um den Arbeitsort und eine virtuelle Vernetzung mittels Plattform – sowie einen sozialen Kontext, mittelbar aus internen Kommunikationsmassnahmen und unmittelbar aus den Erfolgserlebnissen der Arbeitskollegen, um den Umstieg auf Multimodalmobilität zu fördern. Mittels Experteninterviews wird aufgezeigt, dass die fünf Konzerne diverse Mobilitätsangebote stellen, welche den Bedürfnissen der Babyboomer (Status), Generation X (Selbständigkeit), Generation Y (Selbstverwirklichung) und Generation Z („Anything goes“) entsprechen. Basierend auf den theoretischen Grundlagen und explorativen Ergebnissen wird ein exemplarischer Vorschlag für ein generationengerechtes Mobilitätsangebot dargelegt. Die gängigen Mobilitätsmodalitäten werden im Vorschlag nach Geschäfts-, Pendel- und Freizeitreisen ausgerichtet und den Bedürfnissen der Generationen zugeordnet. Flankierende Massnahmen wie die Bildung von Communities sowie weiterführende Handlungsempfehlungen für die Umsetzung wie die Haftungsregelung oder die einfache Verrechnung erhöhen die Praxisbezogenheit der Arbeit.

description: We identify a sample of near-equal mass wide binary M dwarf systems from the SLoWPoKES catalog of common proper-motion binaries and obtain follow-up observations of their chromospheric activity as measured by the H$α$ emission line. We present optical spectra for both components of 48 candidate M dwarf binaries, confirming their mid-M spectral types. Of those 48 coeval pairs, we find eight with H$α$ emission from both components, three with weak emission in one component and no emission in the other, and 37 with two inactive components. We find that of the eleven pairs with at least one active component, only three follow the net trend of decreasing activity strength $L_{\rm Hα}/L_{\rm bol}$ with later spectral type. The difference in quiescent activity strength between the A and B components is larger than what would be expected based on the small differences in color (mass). For five binaries with two active components, we present 47 hours of time-resolved spectroscopy, observed on the ARC 3.5-m over twelve different nights. For four of the five pairs, the slightly redder (B) component exhibits a higher level of H$α$ emission during the majority of the observations and the redder objects are the only components to flare. The full range of H$α$ emission observed on these variable mid-M dwarfs is comparable to the scatter in H$α$ emission found in single-epoch surveys of mid-M dwarfs, indicating that variability could be a major factor in the spread of observed activity strengths. We also find that variability is independent of both activity strength and spectral type.

description: In dieser Studie werden mit Hilfe des Markowitz-Modelles optimale Allokationen für eine typische Schweizer Vorsorgeeinrichtung dokumentiert, die in inländischen Geldmarktanlagen, risikolosen Anleihen, Aktien und Renditeimmobilien investiert ist. Die optimalen Vermögensaufteilungen werden mit und ohne Berücksichtigung von Transaktionskosten berechnet. Aufgrund der vorteilhaften Diversifikationseigenschaften von Renditeimmobilien resultieren optimale Allokationen mit im Vergleich zu den tatsächlichen Anlagen von Schweizer Vorsorgeeinrichtungen (26%) deutlich zu hohen Immobilienanteilen (40%-60%, je nach Risikoaversion), sogar wenn für die Immobilienanlagen verglichen mit den Finanzanlagen relativ hohe Transaktionskosten unterstellt werden. Dieses Ergebnis bestätigt die mit internationalen Daten (d.h. vor allem mit US-, UK- und EU-Daten) erhaltenen Resultate, welche die tatsächlichen Immobilienquoten in den Portfolios institutioneller Anleger (Pensionsfonds) mit optimierten Immobilienanteilen verglichen und die letzteren ebenfalls als zu hoch bewerteten.
On $k$-Bend and Monotonic $\ell$-Bend Edge Intersection Graphs of Paths on a Grid

description: If a graph $G$ can be represented by means of paths on a grid, such that each vertex of $G$ corresponds to one path on the grid and two vertices of $G$ are adjacent if and only if the corresponding paths share a grid edge, then this graph is called EPG and the representation is called EPG representation. A $k$-bend EPG representation is an EPG representation in which each path has at most $k$ bends. The class of all graphs that have a $k$-bend EPG representation is denoted by $B_k$. $B_\ell^m$ is the class of all graphs that have a monotonic $\ell$-bend EPG representation, i.e. an $\ell$-bend EPG representation, where each path is ascending in both columns and rows. It is trivial that $B^m_k\subseteq B_k$ for all $k$. Moreover, it is known that $B^m_k\subsetneqq B_k$, for $k=1$. By investigating the $B_k$-membership and the $B^m_k$-membership of complete bipartite graphs we prove that the inclusion is also proper for $k\in \{2,3,5\}$ and for $k\geqslant 7$. In particular, we derive necessary conditions for this membership that have to be fulfilled by $m$, $n$ and $k$, where $m$ and $n$ are the number of vertices on the two partition classes of the bipartite graph. We conjecture that $B_{k}^{m} \subsetneqq B_{k}$ holds also for $k\in \{4,6\}$. Furthermore, we show that $B_k \not\subseteq B_{2k-9}^m$ holds for all $k\geqslant 5$. This implies that restricting the shape of the paths can lead to a significant increase of the number of bends needed in an EPG representation. So far no bounds on the amount of that increase were known. We prove that $B_1 \subseteq B_3^m$ holds, providing the first result of this kind.
title: Two Ninth-Century Ecclesiastical Initiatives to Legally Define Religious and Secular Duties: Photios I of Constantinople’s Εἰσαγωγὴ τοῦ νόμου and Hincmar of Reims’s Collectio de ecclesiis et capellis

description: Photios’s contribution to the “Introduction to the law” is a “proem” and two titles on secular and religious duties which interpret the power of the patriarch as superior to that of the emperor. The “Introduction to the law” was abrogated after its promulgation. Hincmar’s “Collection concerning Churches and Chapels” also illustrates an ecclesiastical attempt to legally support the Church. I examine two ‘Eastern’ and two ‘Western’ sources: in each case, the first source represents a ninth-century attempt by an ecclesiastic to insert himself into affairs of state, the second source is an eleventh-century text shedding light on the reception of these ideas. Considering the study’s limits, I do not impose theoretical frameworks onto the sources and work with a broad notion of ‘legal’. A situational model explores the question of institution and reveals that the motivation behind the definition of religious and political duties was in both ninth-century initiatives not unification in law.
description: Der Beitrag von Photios zur „Einführung in das Gesetz“ besteht aus einem „Prooimion“ und zwei Titeln zu weltlichen und religiösen Zuständigkeiten, die die Macht des Patriarchen als der des Kaisers überlegen interpretieren. Diese „Einführung“ wurde nach ihrer Promulgation außer Kraft gesetzt. Hinkmars „Sammlung zu Kirchen und Kapellen“ ist ebenfalls ein ekklesialer Versuch, die Kirche rechtlich zu stützen. Ich untersuche zwei ‚östliche‘ und zwei ‚westliche‘ Quellen: Jeweils stellt die erste eine geistliche Initiative aus dem 9. Jh. dar, sich in Staatsangelegenheiten einzumischen. Die zweite, aus dem 11. Jh., gibt Aufschluss über deren Rezeption. Die kurze Studie zwingt den Quellen keinen theoretischen Rahmen auf und arbeitet mit einem umfassenden Begriff von ‚Recht‘. Eine situative Herangehensweise fragt nach der Institutionalisierung dieser Initiativen und zeigt, dass die Motivation hinter der Definition religiöser und politischer Zuständigkeiten nicht Vereinheitlichung im Recht war.
