title: Formen des Nachrichtenkonsums in Japan und Korrelationen mit zwei Dimensionen des subjektiven Glücks
Creators: name: Egger, Veronika
Year: 2024

description: Diese Masterarbeit untersucht auf quantitativer Ebene Korrelationen zwischen dem Konsum von verschiedenen Nachrichtenmedien und dem subjektiven Glücksempfinden sowie der Lebenszufriedenheit in Japan. Im ersten Abschnitt werden Glück und Lebenszufriedenheit definiert und ein historischer Überblick über die Auffassung von Glück dargelegt. Zudem werden Variablen bestimmt, welche das Glück oder die Lebenszufriedenheit beeinflussen können, und die japanische Wahrnehmung von Glück skizziert. Definitionen von Nachrichten, Nachrichtenkonsum in Japan und demographische Unterschiede im Konsum von Nachrichten werden danach beschrieben. Weiters wird zwischen Nachrichtensuchenden und Nachrichtenverweigerern differenziert. Nach einer Beschreibung der bisherigen Forschung über die Zusammenhänge zwischen Nachrichtenkonsum und Emotionen beginnt die statistische Analyse, in welcher neben der deskriptiven und bivariaten Statistik auch die Unterschiede zwischen verschiedenen Konsumentengruppen überprüft werden. Dafür wird der World Values Survey verwendet. Die Berechnungen zeigen, dass es nur wenige leicht statistisch signifikante Korrelationen zwischen dem Glück oder der Lebenszufriedenheit und dem Nachrichtenkonsum über unterschiedliche Medien gibt. Während demographische Unterschiede in der Verwendung von Nachrichtenmedien nachgewiesen werden können, gibt es kaum Anzeichen dafür, dass diese Tendenzen die Personen allgemein glücklicher oder zufriedener im Leben machen oder das Gegenteil bewirken.
description: This master's thesis examines correlations between the consumption of various news media and subjective happiness and life satisfaction in Japan via quantitative statistics. The first section provides definitions to happiness and life satisfaction and presents a historical overview of the concept of happiness. This part also examines variables that can influence happiness or life satisfaction and outlines the Japanese perception of happiness. Definitions of news, news consumption in Japan, and demographic differences within news consumption are described in the next chapter. This section furthermore provides a distinction between news seekers and news avoiders. After providing a summary of previous research on the connections between news consumption and emotions, the statistical analysis begins, in which, in addition to descriptive and bivariate statistics, the differences between different consumer groups are examined with the help of the World Values Survey. The calculations show that there are only a few statistically significant correlations between happiness or life satisfaction and the consumption of different news media. While there are demographic differences in news media consumption, there is little evidence that these trends make people generally happier or more satisfied in life, or have the opposite effect.

description: Single photon detection is a key resource for sensing at the quantum limit and the enabling technology for measurement based quantum computing. Photon detection at optical frequencies relies on irreversible photo-assisted ionization of various natural materials. However, microwave photons have energies 5 orders of magnitude lower than optical photons, and are therefore ineffective at triggering measurable phenomena at macroscopic scales. Here, we report the observation of a new type of interaction between a single two level system (qubit) and a microwave resonator. These two quantum systems do not interact coherently, instead, they share a common dissipative mechanism to a cold bath: the qubit irreversibly switches to its excited state if and only if a photon enters the resonator. We have used this highly correlated dissipation mechanism to detect itinerant photons impinging on the resonator. This scheme does not require any prior knowledge of the photon waveform nor its arrival time, and dominant decoherence mechanisms do not trigger spurious detection events (dark counts). We demonstrate a detection efficiency of 58% and a record low dark count rate of 1.4 per ms. This work establishes engineered non-linear dissipation as a key-enabling resource for a new class of low-noise non-linear microwave detectors.

description: We report on large scale numerical simulations of fracture surfaces using random fuse networks for two very different disorders. There are some properties and exponents that are different for the two distributions, but others, notably the roughness exponents, seem universal. For the universal roughness exponent we found a value of zeta = 0.62 +/- 0.05. In contrast to what is observed in two dimensions, this value is lower than that reported in experimental studies of brittle fractures, and rules out the minimal energy surface exponent, 0.41 +/- 0.01.

Non-occurrence of trapped surfaces and Black Holes in spherical gravitational collapse: An abridged version

description: We have shown in that for arbitrary EOS and radiation transport properties, (even) the idealized spherical gravitational collapse DOES NOT lead to the formation of trapped surfaces: 2GM(r,t)/R <=1. Hence all singularity theorems of Hawking, Penrose and Geroch, built on the assumption of formation of trapped surfaces, get invalidated! And this inequality, demands that M->0 if indeed R->0. We have shown that the final state corresponds to a zero mass BH state and, this state would occur only after infinite proper time indicating that GR is indeed the only naturally singularity free theory for isolated bodies (as was cherished by Einstein). This M->0 state would materialize after the body radiates its entire initial mass-energy. Thus there is no event horizon at any finite R or M, and, therefore all the great theoretical confusions like whether there could be (i) White Holes, (ii) whether t (R) becomes spacelike (timelike) inside the EH (iii) Loss of information in gravitational collapse, and (iv) validity of cosmic censorship conjecture get resolved. At any finite proper time, the collapsed object would be either static (z<2) or may appear static (R almost frozen) though, in extreme cases, internally, in terms of proper radial length, it might be collapsing at a speed ~c! We call the latter as Eternally Collapsing Objects.
description: To be published in the Dec., 2000 issue of Foundation of Physics Letters. Several small changes, more discussion on the nature of Eternally Collapsing Objects (supposed BHs). The problem addressed from 4 directions, (i) Speed of the collapsing fluid must be less than c, (ii) In Sch. coordinates, the metric becomes null on the Event Horizon (EH), (iii) Even in Kruskal coordinates the metric becomes null on the EH, (iv) When crucial errors of Oppenheimer and Snyder paper are removed, they show that trapped surfaces are not allowed

description: We discuss violations of CPT and quantum mechanics due to interactions of neutrinos with space-time quantum foam. Neutrinoless double beta decay and oscillations of neutrinos from astrophysical sources (supernovae, active galactic nuclei) are analysed. It is found that the propagation distance is the crucial quantity entering any bounds on EHNS parameters. Thus, while the bounds from neutrinoless double beta decay are not significant, the data of the supernova 1987a imply a bound being several orders of magnitude more stringent than the ones known from the literature. Even more stringent limits may be obtained from the investigation of neutrino oscillations from active galactic nuclei sources, which have an impressive potential for the search of quantum foam interactions in the neutrino sector.

description: For a harmonic map $\mathcal{F}:\mathcal{Z} {\buildrel {\,harm\,} \over\longrightarrow} \mathcal{W}$ transforming the contour of a corner of the boundary $\partial\mathcal{Z}$ into a rectilinear segment of the boundary $\partial\mathcal{W}$, the behavior near the vertex of the specified corner is investigated. The behavior of the inverse map $\mathcal{F}^{-1}:\mathcal{W} \longrightarrow \mathcal{Z}$ near the preimage of the vertex is investigated as well. In particular, we prove that if $φ$ is the value of the exit angle from the vertex of the reentrant corner for a smooth curve $\mathcal{L}$ and $θ$ is the value of the exit angle from the vertex image for the image $\mathcal{F} (\mathcal{L})$ of the specified curve, then the dependence of $θ$ on $φ$ is described by a discontinuous function.Thus, such a behavior of the harmonic map qualitatively differs from the behavior of the corresponding conformal map: for the latter one, the dependence $θ(φ)$ is described by a linear function.

description: We study the effect of a transport current on the vortex-line lattice in isotropic type-II superconductors in the presence of strong thermal fluctuations by means of 'driven-diffusion' Monte Carlo simulations of a discretized London theory with finite magnetic penetration depth. We calculate the current-voltage (I-V) characteristics for various temperatures, for transverse as well as longitudinal currents I. From these characteristics, we estimate the linear resistivities R_xx=R_yy and R_zz and compare these with equilibrium results for the vortex-lattice structure factor and the helicity moduli. From this comparison a consistent picture arises, in which the melting of the flux-line lattice occurs in two stages for the system size considered. In the first stage of the melting, at a temperature T_m, the structure factor drops to zero and R_xx becomes finite. For a higher temperature T_z, the second stage takes place, in which the longitudinal superconducting coherence is lost, and R_zz becomes finite as well. We compare our results with related recent numerical work and experiments on cuprate superconductors.

description: We study tetraquark resonances using lattice QCD potentials for a pair of static antiquarks $\bar{b}\bar{b}$ in the presence of two light quarks $ud$. The system is treated in the Born-Oppenheimer approximation and we use the emergent wave method. We focus on the isospin $I=0$ channel, but consider different orbital angular momenta $l$ of the heavy antiquarks $\bar{b}\bar{b}$. We extract the phase shifts and search for $\mbox{S}$ and $\mbox{T}$ matrix poles on the second Riemann sheet. For orbital angular momentum $l=1$ we find a tetraquark resonance with quantum numbers $I(J^P)=0(1^-)$, resonance mass $m=10576^{+4}_{-4} \, \textrm{MeV}$ and decay width $Γ= 112^{+90}_{-103} \textrm{MeV}$, which can decay into two $B$ mesons.

Specifically, we develop a formalism employing different sets of amplitude and phase functions --- each set of solutions optimized for a separate region --- and we use these locally adapted solutions to obtain the true value of the scattering phase shift and accurate tunneling rates for ultra-narrow shape resonances. We show results for an illustrative example of an attractive potential with a large centrifugal barrier.

description: The energy spectra of a variety of collective modes on quasiperiodic structures exhibit a complex fractal profile. Among the modes that have attracted particular attention in this context, are the spin wave spectra of quasiperiodic magnetic multilayers that obey a substitutional sequence of the Fibonacci type. They are described within the framework of the Heisenberg theory. In order to have a deep insight on the relevant thermodynamical implications of the above mentioned energy spectra's fractal profile, we have performed analytical and numerical calculations of the spin wave specific heat associated with successive hierarchical sequences of the Fibonacci quasiperiodic structures. The spectra show interesting oscillatory behavior in the low-temperature region, which can be traced back to the spin wave's self-similar energy spectrum.

Using the real space renormalization group approach of Migdal and Kadanoff we find threshold value and all the critical exponents to be strongly nonanalytic functions of ε, e.g. the critical exponent of the conductivity was obtained to be ε^{-2}\exp(-1-1/ε). The main part of the finite size conductivities distribution function at the threshold was found to be universal if expressed in terms of the fluctuating variable, which is proportional to the large power of the conductivity, but with dimensionally-dependent low-conductivity cut-off. Its reduced central momenta are of the order of \exp(-1/ε) up to the very high order.

Do relationship transitions affect body weight? Evidence from German longitudinal data
Creators: name: Huyer-May, Bernadette
Publisher: name: JFR - Journal of Family Research
Year: 2018

description: Despite a considerable amount of empirical studies it is still unclear if changes in union status affect body weight. Using data from the first seven waves of the German Panel Analysis of Intimate Relationships and Family Dynamics (pairfam) project, the current study aims to discover if changes in relationship status lead to changes in body weight considering multiple union transitions with fixed-effects panel regression estimations. Results show that women lose weight within the first year of a relationship, and then gain weight after entering into a non-married cohabiting relationship. Men tend to gain weight from the beginning of the partnership. The results clearly show that the transition from non-married cohabitation to marriage has no significant effect on body weight. Zusammenfassung Trotz zahlreicher Studien gibt es derzeit immer noch keine gesicherten Erkenntnisse darüber, inwieweit partnerschaftliche Veränderungen Einfluss auf das Körpergewicht haben. Basierend auf den Daten der ersten sieben Wellen des deutschen Panels Analysis of Intimate Relationships and Family Dynamics (pairfam) hat diese Studie das Ziel herauszufinden, ob Veränderungen des Beziehungsstatus zu einer Veränderung des Körpergewichts führen. Dabei werden verschiedene partnerschaftliche Übergänge mit Fixed-Effect Panel Regressionen betrachtet. Die Ergebnisse zeigen, dass Frauen in dem ersten Jahr ihrer Beziehung Gewicht verlieren, dann aber an Gewicht zunehmen, wenn sie mit ihrem Partner zusammen ziehen. Männer hingegen tendieren von Beginn an ihrer Beziehung zu einer Gewichtszunahme. Die Ergebnisse zeigen deutlich, dass der Übergang von einer nicht-ehelichen Lebensgemeinschaft zur Ehe keinen Effekt auf das Körpergewicht hat.

description: Every (1 polarization) cylindrical wave solution of vacuum general relativity is completely determined by a corresponding axisymmetric solution to the free scalar wave equation on an auxilliary 2+1 dimensional flat spacetime. The physical metric at radius R is determined by the energy, $γ(R)$, of the scalar field in a box (in the flat spacetime) of radius R. In a recent work, among other important results, Ashtekar and Pierri have introduced a strategy to study the quantum geometry in this system, through a regularized quantum counterpart of $γ(R)$. We show that this regularized object is a densely defined symmetric operator, thereby correcting an error in their proof of this result. We argue that it admits a self adjoint extension and show that the operator, unlike its classical counterpart, is not positive.

description: Despite the well-documented effect of parental attitudes and their socioeconomic status on interethnic partnerships, little is known about how family relations are associated with interethnic partner choices. The present study investigates whether cohesive and affective family ties as well as the family structure is connected to interethnic partnerships. Based on data from wave five of the German Family Panel (pairfam), I estimate logistic regression models for natives and migrants separately. Results indicate that for natives, cohesive and affective relations are not connected to interethnic partnerships. For migrants, cohesive relations have a detrimental effect on being in an interethnic partnership. Overall, these findings suggest that family processes may help to understand why some migrant groups are more likely to be in an interethnic union than others. Zusammenfassung Obwohl der Zusammenhang von Charakteristika der Eltern und ihren Einstellungen gegenüber interethnischen Partnerschaften häufig erforscht wurde, ist die Rolle der Familienbeziehungen unklar. Die vorliegende Studie untersucht den Effekt von kohäsiven, affektiven und diversen Familienbeziehungen auf interethnische Partnerschaften. Basierend auf den Daten der fünften Welle des Deutschen Familienpanels (pairfam) schätze ich logistische Regressionsmodelle für Einheimische und Migranten. Die Ergebnisse zeigen, dass für Einheimische kohäsive und affektive Beziehungen die Partnerwahl nicht betreffen. Bei Migranten wirken hingegen kohäsive Beziehungen negativ auf die interethnische Partnerwahl. Diese Ergebnisse deuten darauf hin, dass Familienbeziehungen wichtig sind um Unterschiede zwischen Migranten in interethnischen Partnerschaften zu verstehen.

description: This study investigated how social media is used by a municipal government agency for communication of citizen coproduction initiatives, through social media content analysis of the government’s official Twitter account. This article identified that the dominant form of social media coproduction in the Bandung municipal government in Indonesia is government-to-citizen (G2C) interaction, focused primarily on informing and nudging (86.62%) citizens, as well as some limited elements of citizen-to-government (C2G) communication, such as citizen sourcing and citizen reporting (8.96%). The municipal government uses various visual tools on Twitter to disseminate G2C information and convey its messages. Regarding the phase of the service cycle, this study found that the majority of social media communications are related to co-assessment (52.26%) and co-designing (42.24%), with a limited number of tweets about co-delivery (3.25%). Based on these findings, this article discusses the shifting relationship between government and citizens brought on by the adoption of this social media platform in its service delivery arrangement.

description: We study the dynamics of brane worlds coupled to a scalar field and gravity, and find that self-tuning of the cosmological constant is generic in theories with at most two branes or a single brane with orbifold boundary conditions. We demonstrate that singularities are generic in the self-tuned solutions compatible with localized gravity on the brane: we show that localized gravity with an infinitely large extra dimension is only consistent with particular fine-tuned values of the brane tension. The number of allowed brane tension values is related to the number of negative stationary points of the scalar bulk potential and, in the case of an oscillatory potential, the brane tension for which gravity is localized without singularities is quantized. We also examine a resolution of the singularities, and find that fine-tuning is generically re-introduced at the singularities in order to retain a static solution. However, we speculate that the presence of additional fields may restore self-tuning.

description: Neutron Scattering measurements for YBa$_2$Cu$_3$O$_{6.6}$ have identified small magnetic moments that increase in strength as the temperature is reduced below $T^\ast$ and further increase below $T_c$. An analysis of the data shows the moments are antiferromagnetic between the Cu-O planes with a correlation length of longer than 195 Åin the $a$-$b$ plane and about 35 Åalong the c-axis. The origin of the moments is unknown, and their properties are discusssed both in terms of Cu spin magnetism and orbital bond currents.

description: Here we develop a microscopic approach aimed at the description of a suite of physical effects related to carrier transport in, and the optical properties of, halide perovskites. Our theory is based on the description of the nuclear dynamics to all orders and goes beyond the common assumption of linear electron-phonon coupling in describing the carrier dynamics and band gap characteristics. When combined with first-principles calculations and applied to the prototypical MAPbI$_{3}$ system, our theory explains seemingly disparate experimental findings associated with both the charge-carrier mobility and optical absorption properties, including their temperature dependencies. Our findings demonstrate that orbital overlap fluctuations in the lead-halide structure plays a significant role in determining the optoelectronic features of halide perovskites.
Collective charge density wave motion through an ensemble of Aharonov-Bohm rings

description: We investigate theoretically the collective charge density wave motion through an ensemble of small disordered Aharonov-Bohm rings. It is shown that the magnetic flux modulates the threshold field and the magnetoresistance with a half flux quantum periodicity $Φ_{0}/2=h/2e$, resulting from ensemble averaging over random scattering phases of multiple rings. The magnitude of the magnetoresistance oscillations decreases rapidly with increasing bias. This is consistent with recent experiments on $NbSe_3$ in presence of columnar defects [Phys. Rev. Lett. 78, 919 (1997)].

title: A detailed look at the adaptive gradient descent method
Creators: name: Harrer, Marcel
Year: 2023

description: Die Suche nach dem optimalen Wert für ein bestimmtes Problem ist das Ziel in einer Vielzahl von wissenschaftlichen Bereichen. Das mathematische Gebiet der Optimierung versucht, dieses Problem unter verschiedenen Annahmen zu lösen. Wegen ihrer geringen Rechenkosten und ihrer breiten Anwendbarkeit sind Methoden erster Ordnung besonders beliebt. Der Gradientenabstieg ist eine Methode erster Ordnung, die für eine Vielzahl von Problemen gut geeignet ist. Obwohl der Gradientenabstieg schon seit langem bekannt ist, schneidet er im Vergleich zu neueren Ansätzen immer noch gut ab, insbesondere bei hochdimensionalen Problemen. Ein Problem des Gradientenabstiegs ist die Bestimmung der zu verwendenden Schrittweite. Im Laufe der Jahre wurden viele verschiedene Ansätze entwickelt, die jedoch alle Nachteile hatten, wie z.B. begrenzte Konvergenzgarantien oder teure Unterprogramme zur Berechnung der Schrittweite. Yura Malitsky und Konstantin Mishchenko verfolgten in ihrer im Jahr 2020 veröffentlichten Arbeit einen neuartigen Ansatz. In dieser Arbeit werden wir ihren neuen Ansatz mit anderen bekannten Gradientenabstiegsalgorithmen vergleichen, und zwar sowohl im Hinblick auf ihren theoretischen Ansatz zum Nachweis der Konvergenz als auch in Bezug auf ihre Leistung bei bestimmten realen Problemen des maschinellen Lernens.
description: Finding the optimal value for a given problem is the goal in a variety of scientific fields. The mathematical field of optimization attempts to solve this problem under various assumptions. Because of their low computational cost and broad applicability, first-order methods are particularly popular. Gradient descent is a first-order method that works well for a variety of problems. Despite the fact that gradient descent has been known for a long time, it still performs well in comparison with newer approaches, especially for high-dimensional data. One issue that gradient descent faces is determining what stepsize to use. Many different approaches have been developed over the years, but they all had drawbacks, such as limited convergence guarantees or expensive subroutines to calculate the stepsize. Yura Malitsky and Konstantin Mishchenko took a novel approach in their paper, which was published in 2020. In this thesis, we will compare their new approach to other well-known gradient descent algorithms in terms of their theoretical approach to proving convergence as well as how well they perform on specific real-world machine learning problems.

description: A four-form gauge flux makes a variable contribution to the cosmological constant. This has often been assumed to take continuous values, but we argue that it has a generalized Dirac quantization condition. For a single flux the steps are much larger than the observational limit, but we show that with multiple fluxes the allowed values can form a sufficiently dense `discretuum'. Multiple fluxes generally arise in M theory compactifications on manifolds with non-trivial three-cycles. In theories with large extra dimensions a few four-forms suffice; otherwise of order 100 are needed. Starting from generic initial conditions, the repeated nucleation of membranes dynamically generates regions with a cosmological constant in the observational range. Entropy and density perturbations can be produced.

Simply the Best!? – Kulturelle Einflussfaktoren zum „intensive mothering“ bei Müttern von Kleinkindern in Deutschland

description: Although young couples often want an egalitarian division of paid and family work, this changes after starting a family. Beside economic reasons, cultural perceptions of a “good mother” can also contribute to this effect. This article investigates how mothers think about “intensive mothering” and live it. This is an ideal which defines the child (and its care) as a woman’s highest priority. A logistic regression analyses is carried out on the basis of the data from the survey about Familienleitbilder to find out who is in favor of “intensive mothering”. It becomes evident, that this is particularly true for West German or religious mothers. A structural equation model shows how this disposition influences the behavior. The belief that the mother is the best caregiver for the child has no direct influence on the actual care, but acts indirect over distrust against external child care. East German or highly educated mothers are less likely to look after their children themselves. This persistent difference between Eastern and Western Germany can be explained by historically grown and intergenerationally transmitted norms. Zusammenfassung Obwohl sich junge Paare oft eine egalitäre Aufteilung der Erwerbs- und Familienarbeit wünschen, ändert sich dies nach der Familiengründung häufig. Neben ökonomischen Gründen können auch kulturelle Vorstellungen von einer „guten Mutter“ diesen Effekt mitverursachen. Im Beitrag wird untersucht, wie Mütter von Kleinkindern zum „intensive mothering“ stehen und dieses leben. Darunter versteht man ein Ideal, welches das Kind (und dessen Betreuung) als höchste Priorität der Frau definiert. Es werden die Daten der Leitbildstudie verwendet und in einer logistischen Regression analysiert, wer das „intensive mothering“ befürwortet. Es zeigt sich u.a., dass dies insbesondere bei westdeutschen und religiösen Müttern der Fall ist. In Strukturgleichungsmodellen wird dargestellt, wie diese Disposition das Verhalten begünstigt. Die Überzeugung, als Mutter die beste Betreuung zu sein, hat keinen direkten Einfluss auf die tatsächliche Betreuung, sondern wirkt indirekt durch das Misstrauen gegenüber der Fremdbetreuung. Ostdeutsche oder höher gebildete Mütter betreuen ihre Kinder seltener selbst. Historisch gewachsene Normen, verstärkt durch intergenerationale Transmission, erklären den persistierenden Ost-West-Unterschied.

description: In order to meet the challenges of the Run 3 data rates and volumes, the ALICE collaboration is merging the online and offline infrastructures into a common framework: ALICE-O2. O2 is based on FairRoot and FairMQ, a message-based, multi-threaded and multi-process control framework. In FairMQ, processes (possibly on different machines) exchange data via message queues either through 0MQ or nanomsg. In turn, this enables developers to write their reconstruction or analysis process in whatever language they choose or deem appropriate for the task at hand, as long as that programming language can send and receive data through these message queues. This paper introduces fer, a Go-based toolkit that interoperates with the C++ toolkit FairMQ, to explore the realm of polyglot distributed frameworks.

description: The current pattern in the mixed state of high-$T_{c}$ superconductors is studied in the U(1) mean field theory of the t-J model. Our findings are the following. 1) In the absence of antiferromagnetism a robust staggered current pattern exists in the core of vortices if the doping is not too high. 2) At a fixed doping and with increasing magnetic field, the size of the staggered current core expands, and eventually percolates. 3) The polarity of the staggered current is pinned by the direction of the magnetic field. 4) Vortex cores locally modify the hole density - in a staggered (non-staggered) core, the excess charge is slightly negative (positive). 5) Gutzwiller projection does not wash out the staggered current. Finally we present two experimental predictions concerning neutron scattering and STM spectra that capture the signature of the staggered current induced by the vortices.
