description: To describe the clinical phenotype of retinitis pigmentosa (RP) caused by PRPF31-variants and clinical characterization of asymptomatic PRPF31 carriers. We conducted a descriptive cross-sectional deep phenotyping study. We included subjects with PRPF31 variants predicted to be disease-causing, both individuals with RP and asymptomatic carriers. Participants underwent a comprehensive clinical examination of standard visual function parameters (visual acuity, contrast sensitivity, Goldmann visual field), full-field stimulus threshold (FST), full-field electroretinogram (ff-ERG), and a structural investigation with slit lamp and multimodal imaging. We used Spearman correlation analyses to evaluate associations between quantitative outcomes. We included 21 individuals with disease-causing PRPF31-variants: 16 symptomatic and 5 asymptomatic subjects. The symptomatic subjects demonstrated a typical RP phenotype with constricted visual fields, extinguished ff-ERG, and disrupted outer retinal anatomy. FST was impaired and correlated significantly with other outcome measures in RP subjects. Structure–function correlations with Spearman correlation analysis showed moderate correlation coefficients due to a few outliers in each analysis. The asymptomatic individuals had normal best-corrected visual acuity and visual fields, but showed reduced ff-ERG amplitudes, borderline FST sensitivity, and structural abnormalities on OCT and fundoscopy. RP11 has a typical RP phenotype but varies in terms of severity. FST measurements correlated well with other functional and structural metrics and may be a reliable outcome measure in future trials as it is sensitive to a broad range of disease severities. Asymptomatic carriers showed sub-clinical disease manifestations, and our findings underline that reported non-penetrance in PRPF31-related RP is not an all-or-none phenomenon.

description: The substructures of light bosonic (axion-like) dark matter may condense into compact Bose stars. We study collapses of the critical-mass stars caused by attractive self-interaction of the axion-like particles and find that these processes proceed in an unexpected universal way. First, nonlinear self-similar evolution (called "wave collapse" in condensed matter physics) forces the particles to fall into the star center. Second, interactions in the dense center create an outgoing stream of mildly relativistic particles which carries away an essential part of the star mass. The collapse stops when the star remnant is no longer able to support the self-similar infall feeding the collisions. We shortly discuss possible astrophysical and cosmological implications of these phenomena.

Commodifying Cult Fitness Through Tribalism: How Elite Fitness Boutiques will Continue to Thrive

description: Spending on health and wellness is growing rapidly, and with it the fitness club industry. In a world where obesity is recognized as an epidemic and there are plentiful forms of free exercise, why are the elite boutique fitness chains thriving? What factors suggest that these high-priced companies will survive while other membership forms of exercise will fade?
My research analyzes the existing scholarly works on tribal marketing, the small body of such studies on fitness fads, and on some of the most popular health club chains. Due to the scarcity of professional theses on the exercise studios, combined with the lack of public financial data on the businesses themselves, I add trend studies authored by the fitness community research associations, personal experience (auto-ethnography), Internet websites and postings – both to add depth and to challenge the conclusions I drew based on the available professional literature. I also connect some more established motivational theories to the newer tribalism studies. My findings offer a uniquely identified roadmap toward the elite boutique fitness clubs’ survival that is not developed elsewhere.
This study identifies that it is the confluence of three key factors that characterize the most successful such “top-end gyms”: (1) adherence to consumer tribal marketing practices;
(2) appeal to self-esteem rather than weight loss goals; and (3) unwavering commitment to higher price tags and luxury branding. In summary, proper social teaming can build aspirational personal identities that stay loyal to a luxe brand. I conclude by addressing issues that may influence the boutiques’ currently stellar growth.

description: With new observational facilities becoming available soon, discovering and characterising supernovae from the first stars will open up alternative observational windows to the end of the cosmic dark ages. Based on a semi-analytical merger tree model of early star formation we constrain Population III supernova rates. We find that our method reproduces the Population III supernova rates of large-scale cosmological simulations very well. Our computationally efficient model allows us to survey a large parameter space and to explore a wide range of different scenarios for Population III star formation. Our calculations show that observations of the first supernovae can be used to differentiate between cold and warm dark matter models and to constrain the corresponding particle mass of the latter. Our predictions can also be used to optimize survey strategies with the goal to maximize supernova detection rates.

Search for Proton Decay via $p \to e^+π^0$ and $p \to μ^+π^0$ in 0.31 megaton$\cdot$years exposure of the Super-Kamiokande Water Cherenkov Detector

description: We have searched for proton decay via $p \rightarrow e^{+} π^{0}$ and $p \rightarrow μ^{+} π^{0}$ using Super-Kamiokande data from April 1996 to March 2015, 0.306 megaton$\cdot$years exposure in total. The atmospheric neutrino background rate in Super-Kamiokande IV is reduced to almost half that of phase I-III by tagging neutrons associated with neutrino interactions. The reach of the proton lifetime is further enhanced by introducing new signal criteria that select the decay of a proton in a hydrogen atom. No candidates were seen in the $p \rightarrow e^{+} π^{0}$ search. Two candidates that passed all of the selection criteria for $p \rightarrow μ^{+} π^{0}$ have been observed, but these are consistent with the expected number of background events of 0.87. Lower limits on the proton lifetime are set at $τ/B(p \rightarrow e^{+} π^{0}) > 1.6 \times 10^{34}$ years and $τ/B(p \rightarrow μ^{+} π^{0}) > 7.7 \times 10^{33}$ years at 90% confidence level.

description: Inosine monophosphate dehydrogenase (IMPDH) is a key regulatory enzyme in the de novo synthesis of the purine base guanine. Mutations in the inosine monophosphate dehydrogenase 1 gene (IMPDH1) are causative for RP10 autosomal dominant retinitis pigmentosa (adRP). This study reports a novel variant in a family with IMPDH1-associated retinopathy. We also performed a comprehensive review of all reported IMPDH1 disease causing variants with their associated phenotype. Multimodal imaging and functional studies documented the phenotype including best-corrected visual acuity (BCVA), fundus photograph, fundus autofluorescence (FAF), full field electroretinogram (ffERG), optical coherence tomography (OCT) and visual field (VF) data were collected. A literature search was performed in the PubMed and LOVD repositories. We report 3 cases from a 2-generation family with a novel heterozygous likely pathogenic variant p. (Lys314Gln) (exon 10). The ophthalmic phenotype showed diffuse outer retinal atrophy with mild pigmentary changes with sparse pigmentary changes. FAF showed early macular involvement with macular hyperautofluorescence (hyperAF) surrounded by hypoAF. Foveal ellipsoid zone island can be found in the youngest patient but not in the older ones. The literature review identified a further 56 heterozygous, 1 compound heterozygous, and 2 homozygous variant. The heterozygous group included 43 missense, 3 in-frame, 1 nonsense, 2 frameshift, 1 synonymous, and 6 intronic variants. Exon 10 was noted as a hotspot harboring 18 variants. We report a novel IMPDH1 variant. IMPDH1-associated retinopathy presents most frequently in the first decade of life with early macular involvement.

description: We propose a new mechanism for thermal dark matter freezeout, termed Co-Decaying Dark Matter. Multi-component dark sectors with degenerate particles and out-of-equilibrium decays can co-decay to obtain the observed relic density. The dark matter density is exponentially depleted through the decay of nearly degenerate particles, rather than from Boltzmann suppression. The relic abundance is set by the dark matter annihilation cross-section, which is predicted to be boosted, and the decay rate of the dark sector particles. The mechanism is viable in a broad range of dark matter parameter space, with a robust prediction of an enhanced indirect detection signal. Finally, we present a simple model that realizes co-decaying dark matter.

description: Waschbeton unterscheidet sich von üblichen Stahlbetonoberflächen nur durch die Oberflächenstruktur. Folglich treten auch hier die bekannten Abplatzschäden über korrodierenden Bewehrungsstählen bei unzureichender Betonüberdeckung oder Betonqualität infolge Karbonatisierung auf. Für Schutz und Instandsetzung von Schäden an Stahlbetonoberflächen gelten die Vorgaben und Anforderungen der ZTV-SIB des BMV bzw. der Rili-Sib des DAfStb derzeit als Stand der Technik. In beiden Regelwerken finden sich jedoch keine Vorgaben oder Hinweise für Schutz und Instandsetzung von Waschbetonoberflächen. Unter Berücksichtigung der Verfahren und Werkstoffe der Regelwerke wurden drei im Erscheinungsbild unterschiedliche Verfahrensweisen zur Instandsetzung von Waschbetonoberflächen in umfangreichen Untersuchungen im Labor und am Bauwerk untersucht. Ein weiterer Schwerpunkt lag auf der Messung und statistischen Auswertung der Schichtdicken der OS-Beschichtung zur Sicherstellung der erforderlichen systemspezifischen Mindestschichtdicke. Aufgrund der Ergebnisse der vorliegenden Arbeit kann davon ausgegangen werden, daß Schutz und Instandsetzung von Waschbetonoberflächen auch unter Erhalt bzw. Wiederherstellung der ursprünglichen Oberflächenstruktur mit den hier ermittelten Werkstoffen und Verfahrensweisen unter Anwendung der erforderlichen Sorgfalt entsprechend dem Stand der Technik möglich ist, wobei das Anlegen von Probeflächen am Bauwerk in jedem Falle unerläßlich ist.
description: The well-known concrete surface damages can also be found on structured concrete surfaces for example washed out or stonemasonry treated ones. The existing technical standards give no instructions for protection and repair of such rough surfaces. In place of other rough surface structures, the suitability of proven repair systems is investigated on laboratory specimens and building test areas with different exposed aggregate concrete surfaces. Focus is to guarantee a durable protection, maintaining or restoring the original surface structure, particularly by producing hole-free coatings with defined thickness. It is the result of the investigations, that it's possible to ensure the so called system-specific minimum thickness of the coatings, if the roughness of the surface is reduced with PCC-mortar and the required mass of fluent coating materials is kept through applying additional layers. To proof visual demands and technical standards test areas should always be carried out, at best before starting restoration.

Ο εντοπισμός των παραγόντων που οδηγούν σε αυτές μπορεί να συντελέσει σε καλύτερες στρατηγικές πρόληψης. Σκοπός της παρούσας μελέτης είναι εξετάσει τη συσχέτιση μεταξύ συγκεκριμένων τοπογραφικά ΜΣΠ και ΜΣΚ σε συνάρτηση με το δείκτη μάζας σώματος (BMI), την ηλικία, το κάπνισμα και την εβδομάδα εκπαίδευσης. Πραγματοποιήθηκε καταγραφή των ΜΣΚ και ΜΣΠ που προέκυψαν κατά τη διάρκεια 3 εβδομάδων εκπαίδευσης νεοσυλλέκτων, σε μονάδα ειδικών δυνάμεων του Ελληνικού Στρατού, για τις 6 ΕΣΣΟ του έτους 2020. Παρατηρήθηκε, μεταξύ του συνόλου των νεοσυλλέκτων (Ν=293), αναζήτηση ιατρικής βοήθειας τουλάχιστον μία φορά από το 30.03% (Ν=88) λόγω ΜΣΠ/ΜΣΚ. Η συχνότερη εντόπιση, το 37% (Ν=36) του συνόλου των περιστατικών (Ν=95), αφορούσε την άρθρωση του γόνατος. Επιπλέον, εμφανίστηκε συσχέτιση ηλικίας και κακώσεων γόνατος, αλλά όχι ηλικίας και λοιπών ΜΣΠ/ΜΣΚ. Δεν παρατηρήθηκε συσχέτιση μεταξύ ΜΣΠ/ΜΣΚ και BMI ή καπνίσματος. Τέλος, υψηλή συχνότητα εμφάνισης παρουσίασε το σύνολο των ΜΣΠ/ΜΣΚ την πρώτη εβδομάδα εκπαιδεύσεως.
description: Musculoskeletal Disorders (MSD) and Musculoskeletal Injuries (MSI) are common causes for military recruits to seek medical care during training. Identifying the factors that lead to MSD/MSI can contribute to better prevention strategies. The purpose of this study is to examine the correlation between specific body site MSD and MSI in relation to body mass index (BMI), age, smoking and week of training. The MSD and MSI that emerged during the 3-week training of recruits in a special forces unit of the Greek Army for the 6 training series of conscripts of the year 2020 were recorded. Among all recruits (N = 293), 30.03% (N = 88) requested medical help at least once due to MSD/MSI. The most common case, 37% (N = 36) of all incidents (N = 95), concerned the knee joint. In addition, there was an association between age and knee injuries, but not between age and other MSD/MSI. No correlation was observed between MSD/MSI and BMI or smoking. Finally, increased frequency of all MSD/MSI presented in the first week of training.

description: Viele industrielle Systeme sind als '' reaktiv`` gekennzeichnet. Reaktive Systeme können zum großen Teil als ereignisgesteuert (engl. event­driven) charakterisiert werden, da sie ständig auf interne und externe Veränderungen reagieren müssen. Zum Beispiel die Bereiche Automobiltechnik (Sicherheits­ und Fahrwerk­Systeme und Elektronik­ und Informations­ Systeme), Kommunikationssysteme (Telefone, Mobiltelefon und Faxgeräte) sowie Medizinische Technik (Patientenüberwachungsysteme) zählen zu reaktiven Systemen. Aufgrund der enormen Folgekosten fehlerhafter und unvollständiger Systemspezifikationen und Entwürfe müssen Techniken, welche die beabsichtigte Funktionalität gewährleisten und frühzeitig Fehler erkennen, weiterentwickelt werden. Insbesondere bei der Modellierung der oben genannten Systeme besteht das Problem darin, eine Sprache zu verwenden, die das dynamische Verhalten eines Systems sowohl klar und intuitiv als auch präzise und formal beschreibt. Solche Formalismen (z. B. Statechart­Modelle) dienen nicht nur als Gegenstand der Kommunikation zwischen Auftraggebern und Entwicklern, sondern unterstützen auch das frühzeitige Testen und Analysieren eines Systems. Aus Sicht der Praxis sind effiziente Methoden und Verfahren zum Erzeugen von Tests eines spezifizierten Systems äußerst wichtig. Durch diese Verfahren werden Fehler gezielt erkannt und behoben, und das Vertrauen in das resultierende System steigt. Daher sind im Rahmen dieser Dissertation Konzepte und Verfahren, die einen Modultest und einen Integrationstest ermöglichen, entwickelt worden. Diese Tests sollen Erzeugung und Durchführung von Tests in frühen Entwurfsphasen unterstützen und die gewünschte Funktionalität höchstmöglich gewährleisten. Dazu sind entsprechende Testkriterien und heuristische Testerzeugungsmethoden für (z. B. Statechart­)Modelle entwickelt worden, die auch auf andere graphbasierte Modelle (z. B. Petri­Netze) anwendbar sind.

description: We use angle-resolved photoemission to study the three dimensional (3D) electronic structure of Co pnictides ACo2As2 with A=Ba, Sr, Ca or a mixture of Sr and Ca. These compounds are isostructural to Fe based superconductors, but have one more electron in the Co $3d$ orbitals. Going from Ba to Ca, they become more and more 3D, eventually forming a 'collapsed' tetragonal phase, where the distance between CoAs layers is markedly reduced. The observed periodicity of the 3D electronic structure matches in each case that expected from the distance between the planes in the bulk. However, the electronic structure is better fitted by a calculation corresponding to a slab with 2 CoAs layers than to the bulk structure. We attribute this to subtle modifications of the 2D electronic structure induced by the truncation of the 3D dispersion at the surface in the ARPES measurement. We further study how this affects the electronic properties. We show that, despite this distortion, the electronic structure of CaCo2As2 is essentially that expected for a collapsed phase. Electronic correlations produce a renormalization of the electronic structure by a factor 1.4, which is not affected by the transition to the collapsed state. On the other hand, a small shift of the Fermi level reduces the density of states in the eg bands and suppresses the magnetic transition expected in CaCo2As2. Our study evidences that observing the bulk periodicity is not sufficient to ensure bulk sensitivity. It further gives direct information on the role of 3D interactions, mostly governed by Co-As hybridization, among eg and t2g orbitals. It is also useful to better understand the electronic structure of Fe superconductors and the range of validity of ARPES measurements.

description: The integration of technological innovations in healthcare is essential for advancing patient care, improving information accessibility, and enhancing inter-professional communication. This transformation, while beneficial, has introduced new responsibilities for nurses, extending beyond traditional patient care to encompass various computer-mediated activities. This shift, however, poses challenges, including limited computer knowledge, time allocation issues, and insufficient training and resources.

This research, employing a descriptive correlational research design, investigates the factors influencing the attitude of nurses towards the use of computers. A purposive sample of 282 registered nurses from a National University Hospital participated in the study. The analysis involved descriptive statistics, Pearson r correlation coefficient, and Analysis of Variance (ANOVA), exploring the interplay between structural empowerment, attitude towards computer use, and demographic variables, such as age, nursing experience, and computer usage duration.

The study conducted at UP – Philippine General Hospital, reveals a moderate level of structural empowerment among nurses, with "opportunities" and "informal power" scoring high. Notably, "resources" received the lowest score, indicating a need for enhanced support. Despite challenges, the majority of nurses exhibited openness to technology, emphasizing the significance of professional growth and peer support. The study unveils a positive attitude towards computer use, with some nurses experiencing cyberphobia. Significantly, a positive and moderate correlation emerged between structural empowerment and computer use attitude, underlining the pivotal role of an empowering work environment.

Demographic variables such as age, nursing experience, and computer usage duration were found to influence both structural empowerment and attitude towards computer use. The findings emphasize the importance of support, information access, formal power, and resources in shaping nurses' professional growth and job satisfaction. Addressing these dimensions is crucial for effective strategies promoting technology adoption, ultimately enhancing healthcare delivery and patient outcomes.

description: Ground level Ozone is one of the six common air-pollutants on which the EPA has set national air quality standards. In order to capture the spatio-temporal trend of 1-hour and 8-hour average ozone concentration in the US, we develop a method for spatio-temporal simultaneous quantile regression. Unlike existing procedures, in the proposed method, smoothing across the sites is incorporated within modeling assumptions thus allowing borrowing of information across locations, an essential step when the number of samples in each location is low. The quantile function has been assumed to be linear in time and smooth over space and at any given site is given by a convex combination of two monotone increasing functions $ξ_1$ and $ξ_2$ not depending on time. A B-spline basis expansion with increasing coefficients varying smoothly over the space is used to put a prior and a Bayesian analysis is performed. We analyze the average daily 1-hour maximum and 8-hour maximum ozone concentration level data of US and California during 2006-2015 using the proposed method. It is noted that in the last ten years, there is an overall decreasing trend in both 1-hour maximum and 8-hour maximum ozone concentration level over the most parts of the US. In California, an overall a decreasing trend of 1-hour maximum ozone level is observed while no particular overall trend has been observed in the case of 8-hour maximum ozone level.

description: A simulation study of the energy released by extensive air showers in the form of MHz radiation is performed using the CoREAS simulation code. We develop an efficient method to extract this radiation energy from air-shower simulations. We determine the longitudinal profile of the radiation energy release and compare it to the longitudinal profile of the energy deposit by the electromagnetic component of the air shower. We find that the radiation energy corrected for the geometric dependence of the geomagnetic emission scales quadratically with the energy in the electromagnetic component of the air shower with a second-order dependence on the atmospheric density at the position of the maximum shower development $X_\mathrm{max}$. In a measurement where $X_\mathrm{max}$ is not accessible, this second order dependence can be approximated using the zenith angle of the incoming direction of the air shower with only a minor loss in accuracy. Our method results in an intrinsic uncertainty of 4% in the determination of the energy in the electromagnetic air-shower component, which is well below current experimental uncertainties.

description: We study spectral and thermodynamic properties of the Sachdev-Ye-Kitaev model, a variant of the $k$-body embedded random ensembles studied for several decades in the context of nuclear physics and quantum chaos. We show analytically that the fourth and sixth order energy cumulants vanish in the limit of large number of particles $N \to \infty$ which is consistent with a Gaussian spectral density. However, for finite $N$, the tail of the average spectral density is well approximated by a semi-circle law. The specific heat coefficient, determined numerically from the low temperature behavior of the partition function, is consistent with the value obtained by previous analytical calculations. For energy scales of the order of the mean level spacing we show that level statistics are well described by random matrix theory. Due to the underlying Clifford algebra of the model, the universality class of the spectral correlations depends on $N$. For larger energy separations we identify an energy scale that grows with $N$, reminiscent of the Thouless energy in mesoscopic physics, where deviations from random matrix theory are observed. Our results are a further confirmation that the Sachdev-Ye-Kitaev model is quantum chaotic for all time scales. According to recent claims in the literature, this is an expected feature in field theories with a gravity-dual.

description: Quanto contano i valori, la visione del mondo e le scelte personali nella ricerca scientificaquando questa si intreccia con la guerra o con finanziamenti legati al militare? Ci piace partireda una domanda che, provocatoriamente, sottolinea il posizionamento di chi fa ricerca rispettoa una presunta neutralità della scienza. E ci piace riflettere attraverso figure di scienziate cheprima di noi si sono interrogate sullo stesso tema e, prendendo posizione, ci offrono deiriferimenti per il nostro agire.“La scienza deve avere come obbiettivo la felicità e la pace tra le persone”. Queste le paroledi Katsuko Saruhashi, fisica giapponese nata nel 1920.La scienziata non esiterà mai a prendere posizione contro la ricerca per scopi militari e controil nucleare. Intuendo da subito le gravi conseguenze degli armamenti nucleari, decide didedicare la sua attività di ricerca allo studio del loro impatto sull’ambiente e la salute. Grazie auna tecnica di misura molto accurata riesce a quantificare l’entità delle ricadute radioattivedovute ai test delle bombe a idrogeno. Il suo messaggio è chiaro: le conseguenze degliesperimenti sono pesanti anche per gli umani. Saruhashi non si limita a comunicare i suoirisultati all’interno della comunità scientifica. Negli anni diventerà in Giappone e nel mondo lavoce scientifica dei movimenti antinucleari, composti in gran parte da donne e madri. Riusciràa stimolare la discussione politica sull’opportunità di condurre i test a livello mondiale.Saruhashi non è l’unica scienziata a compiere delle scelte. Altri, altre lo hanno fattomuovendosi in ambiti e contesti diversi, con visioni differenti, ma con la convinzione condivisache la ricerca scientifica è fatta di scelte personali.Oggi, quando la minaccia di un conflitto globale è tornata ad aleggiare, la denuncia della pacesembra visionaria, ma forse è proprio di questo che abbiamo bisogno.Per approfondire:Scienziate visionarie. 10 storie di impegno per l’ambiente e la salute.

description: In theory, on-demand routing is very attractive for mobile ad hoc networks (MANET), because it induces signaling only for those destinations for which there is data traffic. However, in practice, the signaling overhead of existing on-demand routing protocols becomes excessive as the rate of topology changes increases due to mobility or other causes. We introduce the first on-demand routing approach that eliminates the main limitation of on-demand routing by aggregating route requests (RREQ) for the same destinations. The approach can be applied to any existing on-demand routing protocol, and we introduce the Ad-hoc Demand-Aggregated Routing with Adaptation (ADARA) as an example of how RREQ aggregation can be used. ADARA is compared to AODV and OLSR using discrete-event simulations, and the results show that aggregating RREQs can make on-demand routing more efficient than existing proactive or on-demand routing protocols.

description: To elucidate the pseudogap phase diagram including the overdoped state of high transition temperature (high-$T_c$) cuprates, we must understand the origin of the positive out-of-plane magnetoconductivity (MC) observed in these compounds. For this purpose, the out-of-plane resistivity $ρ_c(T,H)$ of an overdoped Bi$_{1.6}$Pb$_{0.4}$Sr$_{2}$CaCu$_{1.96}$Fe$_{0.04}$O$_{8+δ}$ (Bi-2212) single crystal is measured under pulsed magnetic fields up to 60 T. We show that the superconductive density-of-states (DOS) depletion effect, in addition to the pseudogap effect, clearly appears below the superconductive fluctuation regime, and the contribution becomes dominant in the superconducting state.

description: In diesem Beitrag wird anhand des International Social Survey Programme (ISSP) 1995/96 ein Vergleich der Einstellungen der Bevölkerungen in 24 Ländern zu verschiedenen Aspekten der Beschäftigungs- und Arbeitsmarktpolitik durchgeführt. Ausgehend von einer Klassifizierung der verglichenen Staaten in 6 Typen von Arbeitsmarktsystemen wird zunächst dargestellt, welche Relevanz der Beschäftigungs- und Arbeitsmarktpolitik im Rahmen verschiedener Politikbereiche zukommt. Sodann werden die Unterschiede in den Einstellungen zwischen und innerhalb der sechs Typen von Arbeitsmarktsystemen beschrieben. Schließlich wird durch eine multivariate Analyse untersucht, welche individuellen und makrostrukturellen Merkmale zur Herausformung dieser Einstellungen beitragen. Es scheint weniger auf die Zustimmung oder Ablehnung von beschäftigungspolitischen Maßnahmen an sich anzukommen, wenn es um die Erfolge in arbeitsmarktpolitischer Hinsicht geht, als vielmehr um die Konsistenz eines Beschäftigungssystems insgesamt, der damit verbundenen politischen Ziele wie auch der Einstellungen der Bevölkerung.
description: In this paper, an international comparative analysis of population attitudes towards an employment and labour market policy is carried out. Data are taken from the International Social Survey Programme 1996 (Role of Government III) which included about 26.000 persons in 24 nations around the world. After developing five general hypotheses, we classify the countries compared into 6 types of labour market systems (liberal, corporative, conservative-corporative, egalitarian-inclusive, transformation economies, others). The findings show that there exist significant differences between the countries and labour market types in the support of a labour market policy. General determinants of these attitudes include the level of development and unemployment of a country, and several individual-level variables (socioeconomic status, religion and political affiliation). It is concluded that a successful employment and labour market policy depends strongly on a consistent relationship between institutional and structural preconditions, the policies pursued and the attitudes and behaviours of the population. In this way, we can explain the paradox that both a very liberal and a very egalitarian-inclusive labour market policy seem to be most effective in producing a dynamic employment system and low levels of unemployment.

description: Dissipative quantum systems are frequently described within the framework of the so-called "system-plus-reservoir" approach. In this work we assign their description to the Maximum Entropy Formalism and compare the resulting thermodynamic properties with those of the well - established approaches. Due to the non-negligible coupling to the heat reservoir, these systems are non-extensive by nature, and the former task may require the use of non-extensive parameter dependent informational entropies. In doing so, we address the problem of choosing appropriate forms of those entropies in order to describe a consistent thermodynamics for dissipative quantum systems. Nevertheless, even having chosen the most successful and popular forms of those entropies, we have proven our model to be a counterexample where this sort of approach leads us to wrong results.

A Symplectic Multi-Particle Tracking Model for Self-Consistent Space-Charge Simulation

description: Symplectic tracking is important in accelerator beam dynamics simulation. So far, to the best of our knowledge, there is no self-consistent symplectic space-charge tracking model available in the accelerator community. In this paper, we present a two-dimensional and a three-dimensional symplectic multi-particle spectral model for space-charge tracking simulation. This model includes both the effect from external fields and the effect of self-consistent space-charge fields using a split-operator method. Such a model preserves the phase space structure and shows much less numerical emittance growth than the particle-in-cell model in the illustrative examples.

description: The Schwinger mechanism of electron-positron pair production in the presence of strong external electric fields is analyzed numerically for the case of one- and two-dimensional field configurations where the external field depends both on time and one spatial coordinate. In order to provide this analysis, a new efficient numerical approach is developed. The number of particles created is obtained numerically and also compared with the analytical results for several exactly solvable one-dimensional backgrounds. For the case of two-dimensional field configurations the effects of the spatial finiteness are examined, which confirms their importance and helps us to attest our approach further. The corresponding calculations are also performed for several more interesting and nontrivial combinations of temporal and spatial inhomogeneities. Finally, we discuss the case of a spatially periodic external field when the approach is particularly productive. The method employed is described in detail.
