Ghosting: Romantic Form of Rejection in Online Dating
Creators: name: Kristyawisesagati, Gabriela
Publisher: name: figshare
Year: 2023
Subjects: Social psychology

description: Past studies have revealed that one of the types of online dating rejection is ghosting. There are some studies who found that people who use online dating might be prone to face rejection rather than those in offline dating. This evidence is supported because online dating applications provide more choices and specific features where the users can block or unmatch, and thus demonstrate unresponsive behaviors towards the potential partner. Meanwhile, there are also other studies that generate different findings. These studies discovered that online dating applications are more attractive to people with high sensitivity to rejection because they have more control towards their self-representation image where they can present the aspect of themselves they want others to see in the applications, hence decreasing the probability of being rejected. Furthermore, the rejection itself has some detrimental effects on the well-being of the users in dating applications. Some of the effects are increasing anger, aggression, anxiety, and sadness. These effects can be mitigated by encompassing self-compassion to oneself. By doing that, the impacts of rejection can be minimized.

description: In this paper we show that the real differential of any injective slice regular function is everywhere invertible. The result is a generalization of a theorem proved by G. Gentili, S. Salamon and C. Stoppato, and it is obtained thanks, in particular, to some new information regarding the first coefficients of a certain polynomial expansion for slice regular functions (called \textit{spherical expansion}), and to a new general result which says that the slice derivative of any injective slice regular function is different from zero. A useful tool proven in this paper is a new formula that relates slice and spherical derivatives of a slice regular function. Given a slice regular function, part of its singular set is described as the union of surfaces on which it results to be constant.

description: Kinder und Jugendliche mit beeinträchtigter Lautsprache erhalten durch die Unterstützte Kommunikation (Abkürzung: UK) eine Möglichkeit, sich mitzuteilen und mit ihrem Umfeld in Kontakt zu treten. Mithilfe von Sprachcomputern kann ein grosser Wortschatz aufgebaut werden. Um das geeignete Gerät zu finden und das Umfeld zu schulen, erhalten die Eltern und Fachpersonen ein Gebrauchstraining von den Hilfsmittelfirmen. Daraus ergibt sich die Hypothese, dass im Betreuungsnetzwerk der Kinder und Jugendlichen rund um das Gebrauchstraining eine starke Kooperation notwendig ist, damit sie den Umgang mit dem Sprachcomputer optimal erlernen können. Um diese Hypothese zu überprüfen, wurde eine qualitative Forschung mittels Expert*inneninterviews mit jeweils zwei Eltern, Fachpersonen und Beratungspersonen durchgeführt. Zum Erlangen einer Grundlage wurden dafür die Thematiken der Kommunikationsmöglichkeiten der Unterstützten Kommunikation, der Hilfsmittelversorgung und der Kooperation theoretisch dargestellt. Durch das Erlangen einer theoretischen Basis und den durchgeführten Interviews konnten anschliessend wichtige Schlussfolgerungen für die Praxis gezogen werden. Es deutet darauf hin, dass viele Bedürfnisse und Erwartungen der Beteiligten nicht befriedigt werden können und sich die Zusammenarbeit ändern soll. Auch bei der Umsetzung lässt sich ableiten, dass das Modelling höchste Priorität hat und von den Institutionen verinnerlicht werden sollte. Um das Verständnis für UK in den Institutionen und bei den Fachpersonen zu erhöhen, muss dieses in der Grundausbildung von Sozialpädagog*innen geschult werden und in internen und externen Weiterbildungen immer wieder thematisiert werden.

description: The performance analysis of random vector channels, particularly multiple-input-multiple-output (MIMO) channels, has largely been established in the asymptotic regime of large channel dimensions, due to the analytical intractability of characterizing the exact distribution of the objective performance metrics. This paper exposes a new non-asymptotic framework that allows the characterization of many canonical MIMO system performance metrics to within a narrow interval under moderate-to-large channel dimensionality, provided that these metrics can be expressed as a separable function of the singular values of the matrix. The effectiveness of our framework is illustrated through two canonical examples. Specifically, we characterize the mutual information and power offset of random MIMO channels, as well as the minimum mean squared estimation error of MIMO channel inputs from the channel outputs. Our results lead to simple, informative, and reasonably accurate control of various performance metrics in the finite-dimensional regime, as corroborated by the numerical simulations. Our analysis framework is established via the concentration of spectral measure phenomenon for random matrices uncovered by Guionnet and Zeitouni, which arises in a variety of random matrix ensembles irrespective of the precise distributions of the matrix entries.

A formulation of quantum field theory realizing a sea of interacting Dirac particles
Creators: name: Finster, Felix
Publisher: name: Universität Regensburg
Year: 2009
Subjects: subject: 510 Mathematik

description: In this survey article we explain a few ideas behind the framework of the fermionic projector and summarize recent results which clarify the connection to quantum field theory. The fermionic projector is introduced, which describes the physical system by a collection of Dirac states, including the states of the Dirac sea. Formulating the interaction by an action principle for the fermionic projector, we obtain a consistent description of interacting quantum fields which reproduces all results of perturbative quantum field theory. Moreover, we find a new mechanism for the generation of boson masses

description: A Lie group is called $p$-regular if it has the $p$-local homotopy type of a product of spheres. (Non)triviality of the Samelson products of the inclusions of the factor spheres into $p$-regular $\mathrm{SO}(2n)_{(p)}$ is determined, which completes the list of (non)triviality of such Samelson products in $p$-regular simple Lie groups. As an application, we determine the homotopy normality of the inclusion $\mathrm{SO}(2n-1)\to\mathrm{SO}(2n)$ in the sense of James at any prime $p$.

description: Based on earlier work by the authors, in this paper we introduce novel fully discrete, fully practical parametric finite element approximations for geometric evolution equations of curves in the plane. The fully implicit approximations are unconditionally stable and intrinsically equidistribute the vertices at each time level. We present iterative solution methods for the systems of nonlinear equations arising at each time level and present several numerical results. The ideas easily generalize to the evolution of curve networks and to anisotropic surface energies.

description: We analyze the connectivity of an $M$-layer network over a common set of nodes that are active only in a fraction of the layers. Each layer is assumed to be a subgraph (of an underlying connectivity graph $G$) induced by each node being active in any given layer with probability $q$. The $M$-layer network is formed by aggregating the edges over all $M$ layers. We show that when $q$ exceeds a threshold $q_c(M)$, a giant connected component appears in the $M$-layer network---thereby enabling far-away users to connect using `bridge' nodes that are active in multiple network layers---even though the individual layers may only have small disconnected islands of connectivity. We show that $q_c(M) \lesssim \sqrt{-\ln(1-p_c)}\,/{\sqrt{M}}$, where $p_c$ is the bond percolation threshold of $G$, and $q_c(1) \equiv q_c$ is its site percolation threshold. We find $q_c(M)$ exactly for when $G$ is a large random network with an arbitrary node-degree distribution. We find $q_c(M)$ numerically for various regular lattices, and find an exact lower bound for the kagome lattice. Finally, we find an intriguingly close connection between this multilayer percolation model and the well-studied problem of site-bond percolation, in the sense that both models provide a smooth transition between the traditional site and bond percolation models. Using this connection, we translate known analytical approximations of the site-bond critical region, which are functions only of $p_c$ and $q_c$ of the respective lattice, to excellent general approximations of the multilayer connectivity threshold $q_c(M)$.

Waning of relationship marketing: A grounded theory study of small hotels

Marketing theory

description: Relationship marketing is a popular concept among marketing practitioners and scholars. Since the inception of the concept, it has been evolving for the last four decades. The implications of relationship marketing though proved to be significant in B2B settings and larger organizations, what it means or how it relates to small firms is rarely looked at. This study examines relationship marketing concept in the small hotels’ context. Adopting a grounded theory method in qualitative research strategy the study conducts 15 in-depth interviews between 15/08/2018 and 24/02/2020 with small hotel owners/managers. Participant hotels are independently owned budget hotels within London mainly, except for one in Peterborough. Interview data were systematically analysed with the help of NVivo 12 (software). A thorough literature review was conducted on relationship marketing (RM), small firms’ marketing, planning, market orientation, and networking. The study identifies no strong relationship orientation within the small hotels’ marketing practices. Though relationship orientation was once the main thrust of small hotels’ marketing strategy, the scenario has changed over time. In fact, relationship-driven business in small (budget) hotel sector is in decline significantly which means the practice of relationship marketing is waning in such businesses. Based on the findings, a conceptual model was drawn that illustrates why relationship marketing interests less and is deemed obsolete by small independent hotel owners. Two broad themes in the model: ‘going with the flow’ and ‘give it a go’ explain how waning in relationship marketing practice occurs. Nonetheless, conceptually relationship marketing paradigm is great. However, putting that into practice with theoretical and technological sophistication in small firms can be very difficult or impossible due to their inherent limitations. The study is limited to certain geographical locations and industry-specific. Future research can investigate the relationship marketing concept in different sectors to see the concept in a new light.

description: By generalizing the cosymplectic setting for time-dependent Lagrangian mechanics, we propose a geometric framework for the Lagrangian formulation of classical field theories with a Lagrangian depending on the independent variables. For that purpose we consider the first order jet bundles $J^1π$ of a fiber bundle $π:E\to {\mathbb R}^k$ where ${\mathbb R}^k$ is the space of independent variables. Generalized symmetries of the Lagrangian are introduced and the corresponding Noether Theorem is proved.

description: In this work, we present a homogeneous curve-shifting analysis using the difference-smoothing technique of the publicly available light curves of 24 gravitationally lensed quasars, for which time delays have been reported in the literature. The uncertainty of each measured time delay was estimated using realistic simulated light curves. The recipe for generating such simulated light curves with known time delays in a plausible range around the measured time delay is introduced here. We identified 14 gravitationally lensed quasars that have light curves of sufficiently good quality to enable the measurement of at least one time delay between the images, adjacent to each other in terms of arrival-time order, to a precision of better than 20% (including systematic errors). We modeled the mass distribution of ten of those systems that have known lens redshifts, accurate astrometric data, and sufficiently simple mass distribution, using the publicly available PixeLens code to infer a value of $H_0$ of 68.1 $\pm$ 5.9 km s$^{-1}$ Mpc$^{-1}$ (1$σ$ uncertainty, 8.7% precision) for a spatially flat universe having $Ω_m$ = 0.3 and $Ω_Λ$ = 0.7. We note here that the lens modeling approach followed in this work is a relatively simple one and does not account for subtle systematics such as those resulting from line-of-sight effects and hence our $H_0$ estimate should be considered as indicative.

description: It has become cognitive inertia to employ cross-entropy loss function in classification related tasks. In the untargeted attacks on graph structure, the gradients derived from the attack objective are the attacker's basis for evaluating a perturbation scheme. Previous methods use negative cross-entropy loss as the attack objective in attacking node-level classification models. However, the suitability of the cross-entropy function for constructing the untargeted attack objective has yet been discussed in previous works. This paper argues about the previous unreasonable attack objective from the perspective of budget allocation. We demonstrate theoretically and empirically that negative cross-entropy tends to produce more significant gradients from nodes with lower confidence in the labeled classes, even if the predicted classes of these nodes have been misled. To free up these inefficient attack budgets, we propose a simple attack model for untargeted attacks on graph structure based on a novel attack objective which generates unweighted gradients on graph structures that are not affected by the node confidence. By conducting experiments in gray-box poisoning attack scenarios, we demonstrate that a reasonable budget allocation can significantly improve the effectiveness of gradient-based edge perturbations without any extra hyper-parameter.
Dynamical resonance locking in tidally interacting binary systems

description: We examine the dynamics of resonance locking in detached, tidally interacting binary systems. In a resonance lock, a given stellar or planetary mode is trapped in a highly resonant state for an extended period of time, during which the spin and orbital frequencies vary in concert to maintain the resonance. This phenomenon is qualitatively similar to resonance capture in planetary dynamics. We show that resonance locks can accelerate the course of tidal evolution in eccentric systems and also efficiently couple spin and orbital evolution in circular binaries. Previous analyses of resonance locking have not treated the mode amplitude as a fully dynamical variable, but rather assumed the adiabatic (i.e. Lorentzian) approximation valid only in the limit of relatively strong mode damping. We relax this approximation, analytically derive conditions under which the fixed point associated with resonance locking is stable, and further check these analytic results using numerical integrations of the coupled mode, spin, and orbital evolution equations. These show that resonance locking can sometimes take the form of complex limit cycles or even chaotic trajectories. We provide simple analytic formulae that define the binary and mode parameter regimes in which resonance locks of some kind occur (stable, limit cycle, or chaotic). We briefly discuss the astrophysical implications of our results for white dwarf and neutron star binaries as well as eccentric stellar binaries.

description: This paper disentangles direct spillovers and common factors as sources of correlations in simultaneous heteroscedastic systems. While these different components are not identifiable by standard means without restrictions, it is shown that they can be pinned down by specifying the variances of the latent idiosyncratic and common shocks as ARCH-type processes. Applying an adapted Kalman filter estimation method to Dow and Nasdaq stock returns, predominant spillovers from the Dow and substantial rising factor exposure are found. While the latter is shown to prevail in the recent global financial crisis, volatility in the dot-com bubble period was driven by Nasdaq shocks.

description: We document two stylised facts of US short- and long-term interest rate data incompatible with the pure expectations hypothesis: Relatively slow adjustment to long-run relations and low contemporaneous correlation. We construct a small structural model which features three types of randomness: While a persistent monetary policy shock implies immediate identical reactions through the term structure, both a transitory policy shock and an autocorrelated risk premium allow for the sustained decoupling observed in the data. Indeed, we find important impacts and persistence of risk premia and a decomposition of policy shocks judging a larger part as transitory the longer the investment horizon.

description: The optical hybridization of the electronic states in strongly coupled molecule-cavity systems have revealed unique properties such as lasing, room temperature polariton condensation, and the modification of excited electronic landscapes involved in molecular isomerization. Here we show that molecular vibrational modes of the electronic ground state can also be coherently coupled with a micro-cavity mode at room temperature, given the low vibrational thermal occupation factors associated with molecular vibrations, and the collective coupling of a large ensemble of molecules immersed within the cavity mode volume. This enables the enhancement of the collective Rabi-exchange rate with respect to the single oscillator coupling strength. The possibility of inducing large shifts in the vibrational frequency of selected molecular bonds should have immediate consequences for chemistry.

description: We find general parameterizations for generic off-diagonal spacetime metrics and matter sources in general relativity (GR) and modified gravity theories when the field equations decouple with respect to certain types of nonholonomic frames of reference. This allows us to construct various classes of exact solutions when the coefficients of the fundamental geometric/ physical objects depend on all spacetime coordinates via corresponding classes of generating and integration functions and/or constants. Such (modified) spacetimes display Killing and non-Killing symmetries, describe nonlinear vacuum configurations and effective polarizations of cosmological and interaction constants. Our method can be extended to higher dimensions which simplifies some proofs for embedded and nonholonomically constrained four-dimensional configurations. We reproduce the Kerr solution and show how to deform it nonholonomically into new classes of generic off-diagonal solutions depending on 3-8 spacetime coordinates. Certain examples of exact solutions are analyzed and that are determined by contributions of new type of interactions with sources in massive gravity and/or modified f(R,T) gravity. We conclude that by considering generic off-diagonal nonlinear parametric interactions in GR it is possible to mimic various effects in massive and/or modified gravity, or to distinguish certain classes of "generic" modified gravity solutions which cannot be encoded in GR.

description: The electronic spectra of bromo complexes of main group metal ions with an s2 electronic configuration (SnBr3-, PbBr3-, PbBr42-, SbBr4-, SbBr63-, BiBr4-, BiBr63-) in acetonitrile long-wavelength absorption bands which are assigned to metal-centered sp transitions. Compared to the corresponding chloro complexes the sp bands of the bromo complexes appear at longer wavelength due to sp/LMCT mixing (LMCT=ligand-to-metal charge transfer)
«Albergo eterno d’anime infelici»: visioni e immagini dell’inferno barocco

description: Come aveva dimostrato Piero Camporesi nella Casa dell’eternità (Garzanti, 1987) durante l’epoca controriformistica l’idea di inferno muta radicalmente: non è più quell’ordinata, gerarchizzata struttura a piani digradanti che aveva immaginato Dante nel suo capolavoro, ma un luogo perennemente buio, insieme infuocato e agghiacciato, dove le anime si accalcano l’una sull’altra senza alcun assetto regolare. Tuttavia, questa massa indistinta sollecita la fantasia dei predicatori, che realizzano quadri corruschi di atroci sofferenze e, spingendo la parola nei territori di solito riservati all’immagine, provano a descrivere l’inferno come una sbalorditiva scenografia di fiamme, mostri e atrocità. Immagine e parola si coniugano compiutamente nella Prigione dell’inferno, un’operetta del gesuita modenese Giovan Battista Manni che rappresenta, con le sue incisioni fantasticamente truculente e le successive spiegazioni, l’esempio più pertinente della necessità di mobilitare, oltre alla parola, anche la vista, per instillare nei fedeli la paura del peccato.

description: The main purpose of this paper is to introduce a method to stabilize certain spaces of homomorphisms from finitely generated free abelian groups to a Lie group $G$, namely $Hom(\mathbb Z^n,G)$. We show that this stabilized space of homomorphisms decomposes after suspending once with summands which can be reassembled, in a sense to be made precise below, into the individual spaces $Hom(\mathbb Z^n,G)$ after suspending once. To prove this decomposition, a stable decomposition of an equivariant function space is also developed. One main result is that the topological space of all commuting elements in a compact Lie group is homotopy equivalent to an equivariant function space after inverting the order of the Weyl group. In addition, the homology of the stabilized space admits a very simple description in terms of the tensor algebra generated by the reduced homology of a maximal torus in favorable cases. The stabilized space also allows the description of the additive reduced homology of the individual spaces $Hom(\mathbb Z^n,G)$, with the order of the Weyl group inverted.

title: Stress and coping at the workplace : The role of self-efficacy and social support
Creators: name: Wong, Dominic
Publisher: name: University of Kent
Year: 2022

description: The present research explores whether levels of self-efficacy act as an additional moderator variable in the Job Demand-Control-Support (JDCS) Model, and also examine the role that work support and coping have in predicting health and occupational outcomes. Study 1 and Study 2 sought to identify modifiable factors of the working environment (work support) and the individual (general self-efficacy, work self-efficacy, and coping strategies) that operate through various processes to influence health and occupational well-being. Study 2 was designed to address some of the limitations arising from Study 1, while also endeavouring to discern stronger findings. The JDCS Model was shown to be a stronger predictor of health and occupational outcomes than the JDC Model in both Study 1 and 2. Study 1 supported the addition of general self-efficacy to only the JDC model, and not the JDCS Model. Study 2 supported the addition of work self-efficacy to both the JDC Model and the JDCS Model. Study 3 was an intervention study that was successful in improving work self-efficacy, instrumental support coping, and health and occupational outcomes. These studies contribute additional knowledge about the antecedents and the effects of work stress, and contribute to the understanding of many years of inconsistent evidence concerning the moderating role of self-efficacy, social support, and coping on the stressor-strain relationship in the workplace.

Subjects: citizen science, social sciences, crowdsourcing, metadata

description: Europeana Transcribe is an online crowdsourcing platform for the enrichment of European digital cultural heritage. Our goal is to engage the public in transcribing and annotating Europeana’s vast collection of digitised items. Many of these items, especially those containing handwritten text, hold a treasure trove of hidden information, not yet displayed in the metadata and therefore not readily discernible nor searchable. By transcribing the text, annotating the contents and adding valuable descriptions they can become rich and powerful sources of information. The data gathered can then be checked, sent back to Europeana and become easily read, searched, and categorised to the benefit of the wider public.

description: Functorial semi-norms are semi-normed refinements of functors such as singular (co)homology. We investigate how different types of representability affect the (non-)triviality of finite functorial semi-norms on certain functors or classes. In particular, we consider representable functors, generalised cohomology theories, and so-called weakly flexible homology classes in singular homology and l1-homology.

description: This paper considers the controllability analysis problem for a class of multirotor systems subject to rotor failure/wear. It is shown that classical controllability theories of linear systems are not sufficient to test the controllability of the considered multirotors. Owing to this, an easy-to-use measurement index is introduced to assess the available control authority. Based on it, a new necessary and sufficient condition for the controllability of multirotors is derived. Furthermore, a controllability test procedure is approached. The proposed controllability test method is applied to a class of hexacopters with different rotor configurations and different rotor efficiency parameters to show its effectiveness. The analysis results show that hexacopters with different rotor configurations have different fault-tolerant capabilities. It is therefore necessary to test the controllability of the multirotors before any fault-tolerant control strategies are employed.

description: It is a common method for proving weak convergence of a sequence of time-homogeneous Markov processes towards a time-homogeneous Markov process first to show convergence of the corresponding infinitesimal generators and then to check some additional conditions. The aim of the present paper is to investigate convergence properties of discrete infinitesimal generators of appropriately scaled random step functions formed from a multi-type continuous state and continuous time branching process with immigration. We also present a convergence result for usual infinitesimal generators of the branching processes in question appropriately normalized.

description: This document outlines major directions in theoretical support for the measurement of nucleon resonance transition form factors at the JLab 12 GeV upgrade with the CLAS12 detector. Using single and double meson production, prominent resonances in the mass range up to 2 GeV will be studied in the range of photon virtuality $Q^2$ up to 12 GeV$^2$ where quark degrees of freedom are expected to dominate. High level theoretical analysis of these data will open up opportunities to understand how the interactions of dressed quarks create the ground and excited nucleon states and how these interactions emerge from QCD. The paper reviews the current status and the prospects of QCD based model approaches that relate phenomenological information on transition form factors to the non-perturbative strong interaction mechanisms, that are responsible for resonance formation.
