description: GexPxS1-2x glasses in the compositional range 0.05 < x < 0.19 have been synthesized and examined in temperature modulated differential scanning calorimetry (MDSC) and Raman scattering experiments. Trends in the non-reversing enthalpy DHnr(x) near Tg show the term to almost vanish in the 0.090(5) < x < 0.135(5) range, and to increase by an order of magnitude at x < 0.09, and at x > 0.135. In analogy to previous results on chalcogenide glasses, we identify compositions at x < 0.09 to be elastically floppy, those in the 0.090 < x < 0.135 range to be in the intermediate phase, and those at x > 0.135 to be stressed rigid. MDSC results also show the DHnr term ages in the stressed-rigid and floppy phases but not in the intermediate phase. The intermediate phase is viewed to be a self-organized phase of a disordered network. It consists of at least four isostatically rigid local structures; corner-sharing GeS4, edge-sharing GeS2, pyramidal P(S1/2)3 and quasi-tetrahedral S=P(S1/2)3 units for which evidence comes from Raman scattering. The latter method also shows existence of P4S7 and P4S10 molecules in the glasses segregated from the backbone. These aspects of structure contribute to an intermediate phase that is significantly narrower in width than in corresponding selenide glasses.

description: A simple coherent-imaging method due to Paganin et al. is widely employed for phase-amplitude reconstruction of samples using a single paraxial x-ray propagation-based phase-contrast image. The method assumes that the sample-to-detector distance is sufficiently small for the associated Fresnel number to be large compared to unity. The algorithm is particularly effective when employed in a tomographic setting, using a single propagation-based phase-contrast image for each projection. Here we develop a simple extension of the method, which improves the reconstructed contrast of very fine sample features. This provides first-principles motivation for boosting fine spatial detail associated with high Fourier frequencies, relative to the original method, and was inspired by several recent works employing empirically-obtained Fourier filters to a similar end.

description: A study of fermion nodes for spin-polarized states of a few-electron ions and molecules with $s,p,d$ one-particle orbitals is presented. We find exact nodes for some cases of two electron atomic and molecular states and also the first exact node for the three-electron atomic system in $^4S(p^3)$ state using appropriate coordinate maps and wavefunction symmetries. We analyze the cases of nodes for larger number of electrons in the Hartree-Fock approximation and for some cases we find transformations for projecting the high-dimensional node manifolds into 3D space. The node topologies and other properties are studied using these projections. We also propose a general coordinate transformation as an extension of Feynman-Cohen backflow coordinates to both simplify the nodal description and as a new variational freedom for quantum Monte Carlo trial wavefunctions.

description: The spin dynamics of a hydrogen atom during the passage of a periodic magnetic structure is discussed. The occupation numbers of the components of the hyperfine structure are considered as a function of time. The characteristic low-frequency oscillations are visible, which have a direct analogue in the effect of nuclear magnetic resonance. An envelope forms of these oscillations are found using the Krylov-Bogolyubov-Mitropol'skii method. The dependence of spin dynamics on the parameters of the magnetic structure is investigated. It is shown that this dependence is very sensitive to the structure of the magnetic field.

Increasing functional recovery after a cervical spinal cord injury
Creators: name: Plunet, Ward Thomas
Publisher: name: University of British Columbia
Year: 2010

description: Spinal cord injury (SCI) in adult mammals results in a loss of function with minimal spontaneous recovery due to secondary damage, the inhibitory nature of the injured adult CNS, and the weak intrinsic axonal growth response of injured neurons. In an attempt to increase the weak growth response I tested if pretreatment of rubrospinal neurons with brain-derived neurotrophic factor (BDNF) one week prior to axotomy or at time of injury would produce functional improvements. Both treatments reduced cell body atrophy and dieback of rubrospinal axons, indicating a cell body response was elicited. However, neither BDNF pretreatment nor acute treatment promoted rubrospinal tract regeneration. In addition, the two-fold increase in rubrospinal tract sprouting into the gray matter rostral to the lesion site did not reach significance. Despite the lack of rubrospinal regeneration, BDNF pretreatment improved functional recovery while BDNF-acute treatment had no effect. The BDNF-treated animals had reduced weight gain and BDNF infusion into the brain has been shown to inhibit food intake. Reduced food intake (dietary restriction) is known to extend lifespan since the 1930s but was recently found to be neuroprotective. I explored the possibility that the improved recovery in the BDNF pretreatment animals was mediated via dietary restriction by testing whether every-other-day fasting (EODF) started one month prior to SCI and continued in the post-injury testing period would also prove effective. EODF animals displayed improved functional recovery, reduced GFAP immunostaining, smaller lesion sizes, and greater numbers of healthy neurons surrounding the lesion area. To test a more clinically relevant treatment I next examined if EODF would promote recovery if initiated after a SCI. EODF promoted better recovery on three independent behavioral tests [i.e. behavioural tests]. Lesion size was dramatically reduced and there was an increase of surviving neurons in the EODF animals. Additionally, there was an increase of corticospinal tract sprouting proximal and distal to the lesion site. The expression of trkB (receptor for BDNF) was changed both at, and distal to, the lesion site, which could play a role in both the neuroprotection and increased plasticity observed.

description: We propose Fourier transform (FT) method for processing images of extensive air showers (EAS) detected by imaging atmospheric Cherenkov telescopes (IACT) used in the very high energy (VHE) gamma-ray astronomy. The method is based on the discrete Fourier transforms (DFT) on compact Lie groups, and the use of continuous extension of the inverse discrete transforms to approximate the discrete EAS images by continuous EAS brightness distribution functions. Here we describe the FT-method in case of SU(3) group. It allows practical realization of the DFT technique for functions sampled on hexagonal symmetry grids. The proposed method can also be implemented in case of IACT cameras with grids of rectangular symmetry by using the DFT on the SU(2)xSU(2) group. The proposed FT-method is applied to the Monte-Carlo simulated bank of TeV proton and gamma-ray EAS images for a stand-alone telescope. Comparing between the FT-method and the currently used standard method shows that the FT technique allows a better and systematic enhancement of the gamma-ray signal. The relative difference between these two methods becomes more profound especially for `photon poor' images. It suggests that the EAS detection thresholds of IACTs could be effectively reduced with the use of FT technique. This prediction is further supported by a significant noise suppression capability of the method using simple low-pass filters in the image frequency domain. The FT-method allows very deep `tail' (and `height') image cuts, differentiation of images, operations in the image frequency domain, etc., that can be used for development of new effective parameters for the EAS image processing.

description: The investigation and characterization of topological quantum phase transition between gapless phases is one of the recent interest of research in topological states of matter. We consider transverse field Ising model with three spin interaction in one dimension and observe a topological transition between gapless phases on one of the critical lines of this model. We study the distinct nature of these gapless phases and show that they belong to different universality classes. The topological invariant number (winding number) characterize different topological phases for the different regime of parameter space. We observe the evidence of two multi-critical points, one is topologically trivial and the other one is topologically active. Topological quantum phase transition between the gapless phases on the critical line occurs through the non-trivial multi-critical point in the Lifshitz universality class. We calculate and analyze the behavior of Wannier state correlation function close to the multi-critical point and confirm the topological transition between gapless phases. We show the breakdown of Lorentz invariance at this multi-critical point through the energy dispersion analysis. We also show that the scaling theories and curvature function renormalization group can also be effectively used to understand the topological quantum phase transitions between gapless phases. The model Hamiltonian which we study is more applicable for the system with gapless excitations, where the conventional concept of topological quantum phase transition fails.

description: Surface plasmon polaritons in a strained slab of a Weyl semimetal with broken time-reversal symmetry are investigated. It is found that the strain-induced axial gauge field reduces frequencies of these collective modes for intermediate values of the wave vector. Depending on the relative orientation of the separation of Weyl nodes in momentum space, the surface normal, and the direction of propagation, the dispersion relation of surface plasmon polaritons could be nonreciprocal even in a thin slab. In addition, strain-induced axial gauge fields can significantly affect the localization properties of the collective modes. These effects allow for an in situ control of the propagation of surface plasmon polaritons in Weyl semimetals and might be useful for creating nonreciprocal devices.

description: Charged black holes in anti-de Sitter space become unstable to forming charged scalar hair at low temperatures $T < T_\text{c}$. This phenomenon is a holographic realization of superconductivity. We look inside the horizon of these holographic superconductors and find intricate dynamical behavior. The spacetime ends at a spacelike Kasner singularity, and there is no Cauchy horizon. Before reaching the singularity, there are several intermediate regimes which we study both analytically and numerically. These include strong Josephson oscillations in the condensate and possible 'Kasner inversions' in which after many e-folds of expansion, the Einstein-Rosen bridge contracts towards the singularity. Due to the Josephson oscillations, the number of Kasner inversions depends very sensitively on $T$, and diverges at a discrete set of temperatures $\{T_n\}$ that accumulate at $T_c$. Near these $T_n$, the final Kasner exponent exhibits fractal-like behavior.

E tényezők feltárására irányuló primer kutatásunk eredményei alapján elmondható, hogy a válaszadók többsége elsődleges szempontként tekint a piacképes bérezésre, a női megkérdezettek számára fontosabb az összetartozás iránti szükséglet, mint a férfiaknak, a részmunkaidőben foglalkoztatottak pedig kevesebbszer élnek meg áramlatélményt, mint a teljes munkaidőben foglalkoztatottak, ami feltehetően a rövid munkahelyen töltött idővel van összefüggésben. Habár ezt a kérdéskört nem vizsgáltuk, de eddigi eredményeink megalapozhatják további, a témával kapcsolatos kutatásainkat. -------------------------------------------- Is it possible to reconcile work and happiness? In our research – based on Mihaly Csikszentmihalyi’s Flow theory and Abraham Maslow's Hierarchy of Needs – we were looking for the answer to this question while we were examining workers job choosing attitudes, levels of their needs and the terms of experiencing the flow at workplace. Based on the results of our primary research to explore these factors we can say that the primary job choosing factor is the marketable payment for most of the respondents, for female respondents the need of love and belonging is more important than men, parttime employees living the flow fewer than full-time employees, which may due to the short time spent at work. Although this issue is not examined, our results could help us in our research in the future.
Dynamic patient scheduling for a diagnostic resource
Creators: name: Patrick, Jonathan
Publisher: name: University of British Columbia
Year: 2010

description: We take an in-depth look at the scheduling of patients for a diagnostic resource. Our aim is to schedule patients in order to maintain reasonable waiting times for minimal cost. We assume a fixed capacity with stochastic demand coming from multiple priority classes. We further assume that it is the lower priority patients that must be booked first, therefore requiring the resource manager to implement a booking policy to assure room for later arriving higher priority patients. If too much capacity is reserved for higher priority patients then there will inevitably be unused capacity resulting in longer waiting times than might otherwise be the case. If not enough capacity is reserved then higher priority patients will have to be served through overtime or forced to wait longer than recommended. We begin, in Chapter 1, with an international overview of efforts to reduce waiting times. Chapter 2 proposes a scheduling policy assuming only two priority classes and a fixed limit on expected overtime. The higher priority class are inpatients who must be served the day the demand for a scan is placed. The lower priority class consists of outpatients who may be booked weeks in advance. We present a model that gives the optimal reservation policy and examine the benefit of introducing some flexibility into the higher priority (inpatient) class. Chapter 3 then restricts the modeling to outpatients where demand is divided into multiple priority classes. We present a Markov Decision Process that we solve through approximate dynamic programming in order to derive an approximately optimal booking policy that maintains reasonable waiting times for minimal cost. Chapter 4 presents some strong theoretical results as to the nature of the optimal policy from chapter 3 as well as providing bounds on the "deviation from optimality" associated with our approximation. Chapter 5 then adds inpatients to the model in chapter 3 and compares the results of the full model to those given in chapter 2. Finally, we conclude with possible enhancements to the model and policy insights for the resource manager.
Geometry of random potentials: Induction of 2D gravity in Quantum Hall plateau transitions

description: In the context of the Integer Quantum Hall plateau transitions, we formulate a specific map from random landscape potentials onto 2D discrete random surfaces. Critical points of the potential, namely maxima, minima and saddle points uniquely define a discrete surface $S$ and its dual $S^*$ made of quadrangular and $n-$gonal faces, respectively, thereby linking the geometry of the potential with the geometry of discrete surfaces. The map is parameter-dependent on the Fermi level. Edge states of Fermi lakes moving along equipotential contours between neighbour saddle points form a network of scatterings, which define the geometric basis, in the fermionic model, for the plateau transitions. The replacement probability characterizing the network model with geometric disorder recently proposed by Gruzberg, Klümper, Nuding and Sedrakyan, is physically interpreted within the current framework as a parameter connected with the Fermi level.
Better bound on the exponent of the radius of the multipartite separable ball

description: We show that for an m-qubit quantum system, there is a ball of radius asymptotically approaching kappa 2^{-gamma m} in Frobenius norm, centered at the identity matrix, of separable (unentangled) positive semidefinite matrices, for an exponent gamma = (1/2)((ln 3/ln 2) - 1), roughly .29248125. This is much smaller in magnitude than the best previously known exponent, from our earlier work, of 1/2. For normalized m-qubit states, we get a separable ball of radius sqrt(3^(m+1)/(3^m+3)) * 2^{-(1 + γ)m}, i.e. sqrt{3^{m+1}/(3^m+3)}\times 6^{-m/2} (note that κ= \sqrt{3}), compared to the previous 2 * 2^{-3m/2}. This implies that with parameters realistic for current experiments, NMR with standard pseudopure-state preparation techniques can access only unentangled states if 36 qubits or fewer are used (compared to 23 qubits via our earlier results). We also obtain an improved exponent for m-partite systems of fixed local dimension d_0, although approaching our earlier exponent as d_0 approaches infinity.

Optimization Problems Involving Matrix Multiplication with Applications in Material Science and Biology

description: We consider optimization problems involving the multiplication of variable matrices to be selected from a given family, which might be a discrete set, a continuous set or a combination of both. Such nonlinear, and possibly discrete, optimization problems arise in applications from biology and material science among others, and are known to be NP-Hard for a special case of interest. We analyze the underlying structure of such optimization problems for two particular applications and, depending on the matrix family, obtain compact-size mixed-integer linear or quadratically constrained quadratic programming reformulations that can be solved via commercial solvers. Finally, we present the results of our computational experiments, which demonstrate the success of our approach compared to heuristic and enumeration methods predominant in the literature.

description: We investigate an imbalanced mixture composed of two-color fermions and scalar bosons in the hard-core limit, considering repulsive and attractive interspecies and intraspecies interactions. The interplay between commensurability, repulsive interactions and imbalance generates three insulating phases: a mixed Mott state and two spin-selective insulators characterized by the commensurability relations $ρ_B+ρ^{\uparrow,(\downarrow)}_F=1$. For an attractive coupling between fermions and bosons, we found the relations $ρ_B-ρ^{\uparrow,(\downarrow)}_F=0$ for the spin-selective insulators. State-of-the-art cold-atoms setups constitute ideal platforms to implement these unveiled insulating states and verify their commensurability relations.

In this construction, the Lax connection and spectral parameter of the integrable superstring have a simple geometric origin in four dimensions as gauge connection and reduction coordinate. Kappa symmetry arises as a certain class of singular gauge transformations, while the worldsheet metric comes from complex-structure-changing Beltrami differentials. Our approach offers the possibility of investigating integrable holography using traditional field theory methods.

description: A 20. század végén a globalizáció kiteljesedésével és az infokommunikációs technológiák térnyerésével ismét egy újabb technológiai-gazdasági paradigmaváltás kezdődött el. A világ valamennyi országának új kihívásokkal kellett szembenéznie, melyek felszínre hozták az intézményi gyengeségeket. Az újabb technológiai hullám tovább mélyítette Európában az országok közötti egyenlőségeket, a technológiai rés még nagyobb lett annak ellenére, hogy a képesség- és tudásalapú innovációktól a különbségek mérséklődését várták. A globalizáció kísérőjelenségei a jóléti államokat különösen érzékenyen érintették, a 90-es években az országok többsége válságba került és reformintézkedések végrehajtására kényszerült. Az egyenlőség és hatékonyság sajátos ötvözetét megvalósító jóléti rendszerek sajátos intézményi környezetet teremtettek a technológiai fejlődésnek, melynek köszönhetően a világ leginnovatívabb gazdaságaivá váltak. A tanulmány a skandináv jóléti államok közül Svédország sajátosságait kiemelve mutatja be, hogyan tudtak ezek a gazdaságok a megváltozott környezetben egyedi innovatív fejlődési pályára állni. --------------------------------------------- At the end of 20th century, the advancement of globalisation and spread of information and communication technologies launched a new techno-economic paradigm shift. All countries in the world had to face new challenges, which have highlighted the institutional weaknesses. In Europe, the new technology wave contributed to the widening of equality between countries. The technology gap became greater despite the fact that the skill- and knowledge-based innovation can moderate these differences. Welfare states were sensitive to the accompanying phenomena of globalization. In the nineties, most welfare states faced crises and had to implement reforms. Welfare states implemented a specific combination of equality and efficiency. Doing so, they became the world’s most innovative economies due to the special institutional environment which favour technological progress. This paper present the institutional specialities of Sweden, which is a typical Scandinavian welfare state, and its unique innovative development path in changed environment.
title: The impact of the Norman invasion on the Gower Peninsula
Creators: name: Bourne, Caroline
Publisher: name: University of Reading
Year: 2025

description: This thesis presents an assessment of the impact of Norman influence on the Gower region in south 
Wales. It uses an interdisciplinary approach, due to limited documentary sources for the twelfth 
century relating to Gower. The main focus of this thesis is the impact of the creation of the lordship 
of Gower early in the twelfth century, due to Norman expansion into Wales from England. As 
relatively little is known of Gower during this period, traditional narratives adopted by modern 
historians have been established in the absence of evidence that assert there was a swift and 
comprehensive conquest, immediately followed by the widespread building of stone churches and 
extensive English colonisation. This thesis challenges these narratives, providing a historical 
framework which represents a fundamental shift in the way in which Gower’s early history is 
perceived. It argues that far from being swift and comprehensive, it was not until the end of the 
twelfth century, rather than the beginning, that the situation in Gower resembled the traditional 
narratives. By using a progressive methodology of exploring Gower in the Early Medieval period, the 
impact of Norman influence can be assessed far more comprehensively than previous studies. This 
thesis takes a thematic approach, covering ecclesiastical development, secular power and 
settlement. Each theme has two chapters, one investigating the development of Gower during the 
Early Medieval period in relation to the twelfth century and the other assessing the impact of 
Norman influence. This thesis argues that during the twelfth century, Gower’s historical processes 
were defined more by continuity, rather than by rapid change.

description: Nanoelectromechanical systems (NEMs) hold promise for a number of scientific and technological applications. In particular, NEMs oscillators have been proposed for use in ultrasensitive mass detection, radio-frequency signal processing, and as a model system for exploring quantum phenomena in macroscopic systems. Perhaps the ultimate material for these applications is a carbon nanotube. They are the stiffest material known, have low density, ultrasmall cross-sections and can be defect-free. Equally important, a nanotube can act as a transistor and thus may be able to sense its own motion. In spite of this great promise, a room-temperature, self-detecting nanotube oscillator has not been realized, although some progress has been made. Here we report the electrical actuation and detection of the guitar-string-like oscillation modes of doubly clamped nanotube oscillators. We show that the resonance frequency can be widely tuned and that the devices can be used to transduce very small forces.

description: Device use in smart homes is becoming increasingly communal, requiring cohabitants to navigate a complex social and technological context. In this paper, we report findings from an exploratory survey grounded in our prior work on communal technology use in the home [4]. The findings highlight the importance of considering qualities of social relationships and technology in understanding expectations and intentions of communal technology use. We propose a design perspective of social expectations, and we suggest existing designs can be expanded using already available information such as location, and considering additional information, such as levels of trust and reliability.

description: Die großen stillgelegten Gegenden in der Bucht der Stadt Pula befinden sich derzeit an einem entscheidenden Moment. Der Militärstützpunkt, der einen Großteil der Fläche eingenommen hatte, wird sukzessive aufgelassen und der freigewordene Raum wird der Stadt überlassen. Davon übrig bleibt eine Vielzahl an stillgelegten, nun leerstehenden Gebäuden über, die Teil der von dem Militär aufgebauten enormen Infrastruktur waren und in einem Zeitraum von zwei Jahrhunderten aufgebaut wurden und weiters große Geländeflächen, die großteils noch in ihrer natürlichen Struktur erhalten sind. Die Stadtregierung, die sich der Möglichkeit von schnellem Profit und temporärem Arbeitsaufschwung bewusst ist, planen dieses Territorium mit Resorts und Hotels zu bebauen, und damit wiederum die Einwohner von der Meeresküste abzuschneiden und die Gegend der gewohnten Funktion vergleichbarer Städte hinzugeben: dem Tourismus. Der Versuch dieses Projektes ist es, einen Strategieplan zu entwickeln für eine Richtlinie einer Transformation, welche dazu beitragen würde den Stadtkern von Pula, den restlichen Küstenbereich und die umliegenden Vorstadtbereiche zu verbinden. Dies würde ermöglicht, indem neue öffentliche Funktionen angeboten werden und ein Neuaufleben des Stadtlebens an der Küste zugelassen wird durch das bereicherte Zusammenleben von Tourismus und zusätzlicher Aktivitäten für die Einwohner..
description: The large closed off areas, in the bay of the city of Pula, are seeing a crucial moment as the military is abandoning slowly the territory and leaving them to the use of the city.Left behind are large number of abandoned buildings, part of the massive military infrastructure built in the period of two centuries and vast areas in their almost intact natural condition. The authorities, aware of the possibility of fast profit and temporary creation of employment, are planning to convert these territories into resorts and hotels, cutting once again parts of the bay from the citizens and assigning them, once again, to one prevalent function: tourism. The aim of this project is to create a strategy plan providing general guidelines of transformation that would integrate the city of Pula, the rest of the bay and the surrounding suburban settlements together, producing new public functions and permitting the re-emergence of the city on the coastline by creating a network of touristic and supplementary activities on the bay.

description: Iron is an important sheath material for fabrication of MgB2 wires. However, the effect of Fe doping on the superconducting properties of MgB2 remains controversial. In this work, we present results of nano-scale Fe particle doping in to MgB2. The Fe doping experiments were performed using both bulk and thin film form. It was found that Fe doping did not affect the lattice parameters of MgB2, as evidenced by the lack of change in the XRD peak positions for MgB2. Because of the high reactivity of nano-scale Fe particles, Fe doping is largely in the form of FeB at low doping level while Fe2B was detected at 10wt% doping by both XRD and TEM. There is no evidence for Fe substitution for Mg. The transition temperature decreased modestly with increasing Fe doping levels. The Jc(H) performance was severely depressed at above 3wt% doping level. The detrimental effect of nano-scale Fe doping on both Tc and Jc(H) is attributable to the grain decoupling as a result of magnetic scattering of Fe-containing dopants at grain boundaries.

description: By using deep observations of clusters of galaxies, it has been recently found that the projected stellar mass density closely follows the projected total (dark and baryonic) mass density within the innermost ~140 kpc. In this work, we aim to test these observations using the Cluster-EAGLE simulations, comparing the projected densities inferred directly from the simulations. We compare the iso-density contours using the procedure of Montes \& Trujillo (2019), and find that the shape of the stellar mass distribution follows that of the total matter even more closely than observed, although their radial profiles differ substantially. The ratio between stellar and total matter density profiles in circular apertures, shows a slope close to -1, with a small dependence on the cluster's total mass. We propose an indirect method to calculate the halo mass and mass density profile from the radial profile of the intra-cluster stellar mass density.

description: Az 1990-es évek elején, ahogy az európai országokban általában, mind Magyarországon, mind az Egyesült Királyságban illegálissá vált a zárt üzem. Az adatok az 1999 és 2008 közötti időszakra vonatkozóan teszik lehetővé a potyautasok arányának meghatározását a két országban: a potyautas-arány Magyarországon 52 százalék körül alakul, az Egyesült Királyságban körülbelül 19 százalék. Jelen írás célja, hogy feltárja a potyautas-aránybeli különbségek lehetséges okait, illetve lehetőség szerint összehasonlítsa a magyar és a brit potyautasok jellemzőit. A tanulmány legfőbb megállapítása ezzel kapcsolatban, hogy a szakszervezetek elérhetősége, eredményessége és a csatlakozási költségek fontos szerepet játszanak abban, hogy a magyar munkavállalók nagyobb arányban válnak potyázókká, mint brit társaik ---------------------------------------------At the beginning of the 1990s compulsory membership became illegal across the European countries, as well as in Hungary and in the United Kingdom. Data permit calculation of the proportion of free-riders in the two countries between 1999 and 2008. The free-rider ratio is around 52 percent in Hungary and about 19 percent in the United Kingdom. This paper aims to explore possible reasons of the differences in free-rider rates and to compare characteristics of Hungarian and British free-riders. The main findings of this study is that union availability, union efficiency and joining costs play an important role in the higher proportion of Hungarian free-riders than their British counterparts.

description: COVID-19 poses a major challenge to care homes, as SARS-CoV-2 is readily transmitted and causes disproportionately severe disease in older people. Here, 1167 residents from 337 care homes were identified from a dataset of 6600 COVID-19 cases from the East of England. Older age and being a care home resident were associated with increased mortality. SARS-CoV-2 genomes were available for 700 residents from 292 care homes. By integrating genomic and temporal data, 409 viral clusters within the 292 homes were identified, indicating two different patterns – outbreaks among care home residents and independent introductions with limited onward transmission. Approximately 70% of residents in the genomic analysis were admitted to hospital during the study, providing extensive opportunities for transmission between care homes and hospitals. Limiting viral transmission within care homes should be a key target for infection control to reduce COVID-19 mortality in this population.

description: Az önkormányzati tulajdonú gazdasági társaságok biztosítják a lakosság számára fontos közszolgáltatások jelentős hányadát, így működésük, gazdálkodásuk minősége a tulajdonos önkormányzatok számára is nagymértékű figyelmet igényel, ezzel egyetemben kockázatok hordozója is lehet. Tanulmányomban a megyei jogú városok, a Főváros és a fővárosi kerületek cégeit vizsgáltam meg 2010-2013 között, likviditás, bonitás, rentabilitás szempontjából. Hipotézisként azt fogalmaztam meg, hogy működési és tőkeszerkezeti jellemzők a vizsgált vállalkozások döntő hányadában megfelelőek voltak. A vizsgálatok során évenként változó számú (183-334 db) vállalatot vizsgáltam meg klaszteranalízis segítségével, a vizsgálatba vont változókat a mérleg és eredménykimutatásból származó mutatókra alapoztam. Tanulmányból képet kaphatunk az önkormányzati cégek gazdálkodásáról, és azok időbeli változásáról. ------------------------------------------------ The government-owned business organizations provide a significant proportion of important public services to the population, thus the quality of their operation and management is important to the owner local governments which at the same time can also pose risks. In my study, I examined county towns, the capital and capital districts between 2010-2013 in terms of liquidity, creditworthiness and profitability. As a hypothesis, I assumed that the characteristic of operating and capital structure were appropriate in most analyzed companies. I examined a changing number of companies annually (184-334 units) using claster analysis, variables used in the study were imported from balance sheets and income statements. From the study, we can get a picture of the operation and temporal changes of local governments.
