description: A homology cylinder over a compact manifold is a homology cobordism between two copies of the manifold together with a boundary parametrization. We study abelian quotients of the homology cobordism group of homology cylinders. For homology cylinders over general surfaces, it was shown by Cha, Friedl and Kim that their homology cobordism groups have infinitely generated abelian quotient groups by using Reidemeister torsion invariants. In this paper, we first investigate their abelian quotients again by using another invariant called the Magnus representation. After that, we apply the machinery obtained from the Magnus representation to higher dimensional cases and show that the homology cobordism groups of homology cylinders over a certain series of manifolds regarded as a generalization of surfaces have big abelian quotients. In the proof, a homological localization, called the acyclic closure, of a free group and its automorphism group play important roles and our result also provides some information on these groups from a group-theoretical point of view.

description: Immunologische Ursachen für psychiatrische Erkrankungen geraten zunehmend in den Fokus der aktuellen Forschung. Entsprechend konnten proinflammatorische Zellen und Botenstoffe im Hirnparenchym aber auch im peripheren Blut und Liquor von Schizophrenen und Patienten mit affektiven Störungen nachgewiesen werden. Ähnlich anderer neuroimmunologischer Erkrankungen scheint dabei die Permeabilität der Bluthirnschranke für immunreaktive Zellen relevant zu sein. In der vorliegenden Post-mortem-Studie wurden koronare Ganzhirnschnitte des Frontal- und vorderen Temporalhirns von 20 Schizophrenen (paranoid und residual), 19 Depressiven (unipolar und bipolar), sowie 19 psychisch gesunden Kontrollfällen untersucht. Nach immunhistochemischer Einfärbung der Hirnschnitte wurden diese auf Vorhandensein von T- und B-Lymphozyten, als Hinweis auf neuroinflammatorische Prozesse, überprüft. Es kamen zwei unterschiedliche Methoden zur Anwendung: ein semiquantitativer Ansatz, bei der eine manuelle mikroskopische Durchsicht aller Hirnschnitte mit anschließender Einordung in mengenmäßige Kategorien erfolgte, und ein quantitatives Verfahren, mit automatisierter Registrierung von Zellzahlen mittels Bildanalyseprogramm. Beide Methoden zeigten signifikante oder nahezu signifikante Erhöhungen von CD20-positiven (B-) Zellen bei Depressiven im Vergleich zu Gesunden im orbitalen und hochfrontalen Kortex, sowie im temporalen Marklager. Auch nach Analyse des Einflusses möglicher konfundierender Variablen wie Fixationszeit, Krankheitsdauer und Suizid durch Strangulation deuten die Ergebnisse auf einen immunologischen Faktor, als neuroinflammatorische Teilursache, von affektiven Erkrankungen bei gestörter Bluthirnschranke hin.
“…and I dropped my jaw with fear”: The role of corpora in teaching phraseology

description: How can the effects of corpora on the language learning process be effectively assessed? This is an old question which is, however, just as important now as it was ten or twenty years ago. Does corpus use aid students in a measurable way? How does corpus use affect students’ subsequent language use? Is there a marked qualitative difference between the work of students who make use of corpora in their studies and those who do not? Does corpus use necessarily lead to an improvement in students’ language production?
This research reports an ongoing study into phraseological production in advanced learner writing (Philip 2005a; 2005b; 2006/forthcoming); in particular, it investigates corpus use and non-use in a semi-structured writing task. Unlike other studies in the EFL literature, this research examines multiple versions of a single base text, making it possible to observe what effect the use of corpora has on the production of phraseological units in text, rather than in gap-fill sentences or other, more traditional types of elicitation experiment, such as those found in Deignan et al. (1997 and Boers (2000). The rationale behind the present approach is influenced by the use of parallel corpora in translation studies in which multiple versions of single texts – in two or more languages – can be visualised and examined as KWIC concordances.
The data presented here has been gathered from five groups of advanced learners between March 2005 and June 2006. The learners, following advanced (C1) general English courses at the University of Bologna. Four of the groups have used corpora during the course of their studies; of these four groups of corpus users, two have used corpora extensively, and have been taught how to carry out advanced searches (multiple nodes, wildcards, and node plus tag). The fifth group, having had no exposure to language corpora, serves as a control.

description: The many body quantum dynamics of dipolar coupled nuclear spins I = 1/2 on an otherwise isolated cubic lattice are studied with nuclear magnetic resonance (NMR). By increasing the signal-to-noise ratio by two orders of magnitude compared with previous reports for the free induction decay (FID) of 19F in CaF2 we obtain new insight into its long-time behavior. We confirm that the tail of the FID is an exponentially decaying cosine, but our measurements reveal a second universal decay mode with comparable frequency but twice the decay constant. This result is in agreement with a recent theoretical prediction for the FID in terms of eigenvalues for the time evolution of chaotic many-body quantum systems.

description: Nell’ambito della verifica di collisione fra corpi l’efficienza degli algoritmi gioca un ruolo fondamentale
congiuntamente alla precisione nella valutazione dei contatti. Molte delle tecniche adottate in letteratura per
risolvere tale problematica si basano sull’approssimazione degli oggetti in studio mediante l’uso di primitive
elementari quali, ad esempio, sfere. Efficienza e precisione degli algoritmi sono aspetti strettamente correlati
alla qualità di rappresentazione degli oggetti. In questo lavoro viene presentato un nuovo indice che confronta,
in termini di qualità di rappresentazione, i differenti algoritmi che approssimano un oggetto mediante primitive
sferiche. La validazione dei risultati viene ottenuta attraverso l’analisi ed il confronto con altri indici presenti in
letteratura. La validità dell’indice proposto viene infine messa in luce da un’applicazione ad un corpo a
geometria complessa quale è la tibiotarsica umana.

Both algorithm efficiency and contact evaluation accuracy play a key role when dealing with the problem of
Collision Detection. Several techniques from the literature used to solve this problem are based on the object
representation by means of spheres. Efficiency and precision of the algorithms are closely connected to the
quality of the representation of the objects. In this report, a new index which evaluates the approximation quality
of the representation of the object with spheres is presented. Comparing the proposed index with other indexes
from previous researches proves its correctness. Finally, as an example of application to a complex geometry
bone, from the human ankle highlights the efficiency of the index.

description: Zielsetzung: Hörstörungen bei Patienten mit Autoimmunerkrankungen, wie z. B. Granulomatose mit Polyangiitis (GPA, Wegenersche Granulomatose) und rheumatoider Arthritis (RA), sind umstritten. In vielen Studien fehlen Kontrollgruppen oder Vergleiche mit einer altersbedingten normalen Hörschwelle. Methoden: In dieser Studie wurde das Hörvermögen mit einer erweiterten audiologischen Testbatterie untersucht. Insgesamt wurden 22 Erwachsene mit RA, 16 mit GPA und eine für Alter und Geschlecht ähnliche Kontrollgruppe (n=34) einbezogen. Untersucht wurden die Reinton-Hörschwelle, die Sprachwahrnehmung in Ruhe und im Lärm, die Tympanometrie und distorsionsproduzierte otoakustische Emissionen (DPOAE). Ergebnisse: GPA-Patienten wiesen im Vergleich zur Kontrollgruppe ein beeinträchtigtes Reintonhörvermögen auf, RA-Patienten dagegen nicht. Bei GPA-Patienten wies eine größere ABG auf eine Schallleitungsschwerhörigkeit hin. Darüber hinaus war die Sprachwahrnehmung ausschließlich bei GPA-Patienten eingeschränkt. Es wurde eine signifikante Korrelation zwischen dem Hörverlust und der kumulativen Steroiddosis bei GPA-Patienten festgestellt.
description: Objectives: Hearing loss in patients with autoimmune diseases, such as granulomatosis with polyangiitis (GPA, Wegener’s granulomatosis) and rheumatoid arthritis (RA), is controversial. Many studies lack control groups or comparisons to an age-related normal hearing threshold. Methods: This study investigates hearing performance with an extended audiological battery. A total of 22 adults with RA, 16 with GPA and one age- and gender-matched control group (n=34) were included. Pure-tone hearing thresholds, speech perception in quiet and noise, tympanometry, and distorsion product otoacoustic emissions (DPOAE) were assessed. Results: GPA patients exhibited impaired pure-tone hearing compared to the control group, whereas RA patients did not. In GPA patients, a larger air-bone gap indicated conductive hearing loss. In addition, speech perception was reduced exclusively in GPA patients. A significant correlation was found between hearing loss and the cumulative steroid dose in GPA patients.

description: Cascade processes are responsible for many important phenomena in natural and social sciences. Simple models of irreversible dynamics on graphs, in which nodes activate depending on the state of their neighbors, have been successfully applied to describe cascades in a large variety of contexts. Over the last decades, many efforts have been devoted to understand the typical behaviour of the cascades arising from initial conditions extracted at random from some given ensemble. However, the problem of optimizing the trajectory of the system, i.e. of identifying appropriate initial conditions to maximize (or minimize) the final number of active nodes, is still considered to be practically intractable, with the only exception of models that satisfy a sort of diminishing returns property called submodularity. Submodular models can be approximately solved by means of greedy strategies, but by definition they lack cooperative characteristics which are fundamental in many real systems. Here we introduce an efficient algorithm based on statistical physics for the optimization of trajectories in cascade processes on graphs. We show that for a wide class of irreversible dynamics, even in the absence of submodularity, the spread optimization problem can be solved efficiently on large networks. Analytic and algorithmic results on random graphs are complemented by the solution of the spread maximization problem on a real-world network (the Epinions consumer reviews network).

description: Questo contributo presenta alcune riflessioni relative alla manifestazione dell’idea di futurità e alla sua traduzione, a partire dalla lingua italiana, in tre lingue: l’italiano, il francese e l’inglese.  Scopo del lavoro è illustrare la maniera in cui le tre lingue indoeuropee, appartenenti a gruppi linguistici differenti, romanzo per quanto concerne l’italiano ed il francese, germanico nel caso dell’inglese, indicano la nozione di futuro verbale nei tre rispettivi codici. Sulla scorta di un breve corpus scritto composto da sei testi (due per lingua), si verificano le somiglianze tra le tre lingue e le eventuali costanti che mostrano, rispetto ad una differenziazione apparentemente forte, dei tratti comuni relativamente all’oggetto di studio qui presentato.  Il corpus, articolato in tre distinti sotto-corpora, uno per lingua, consta di testi specialistici appartenenti all’ambito della stampa, in particolare alla sezione dell’economia di tre quotidiani.   Appare fondamentale, trattandosi di un corpus trilingue, concentrarsi sulla prospettiva contrastiva, per poter evincere le modalità in cui la futurità viene espressa nell’ambito del discorso economico scritto.  Chiude l'articolo un breve profilo traduttivo della futurità che mira alla resa in italiano, oltre che dei futuri propriamente detti (futuro semplice e anteriore italiano e francese;  will in forma semplice e composta per l’inglese), dei “futurs proches”, dei verbi modali e delle perifrasi verbali “futurali” cui possono far ricorso i locutori italofoni, francofoni e anglofoni.

Wir nehmen an, dass sowohl die Hirnstruktur als auch die funktionellen Aktivierungsmuster von Risikoallel-Trägern sich signifikant von denen der Nichtrisikoallel-Träger unterscheiden. Des Weiteren erwarten wir signifikante Effekte von Diagnose und kindlichem Missbrauch (CA). Dafür wurden 160 Probanden genotypisiert, psychopathologisch befundet und gescannt. Bei der funktionellen MRT bearbeiteten die Probanden eine Aufgabe, bei der sie horizontale und vertikale Bilder von Gesichtern mit positiven, neutralen oder negativen Ausdrücken betrachten und dann eine Frage entweder zur emotionalen Valenz oder zur Bildausrichtung per Knopfdruck beantworten mussten. In der strukturellen Analyse ergaben sich zahlreiche Haupteffekte der Diagnose in frontalen, limbischen, sensomotorischen und okzipitalen Regionen, jedoch keine Effekte der SNPs oder von CA. In der funktionellen Analyse zeigten sich Effekte der Diagnose in limbischen, sowie in frontalen, temporalen und motorischen Kortexanteilen. Effekte von CA traten vor allem in visuellen, sensomotorischen, limbischen und frontalen Kortizes auf. Rs220549 zeigte in der funktionellen Analyse Effekte im mittleren frontalen Gyrus links, im linken parazentralen Gyrus, in der rechten Insel, im linken MCC und PCC sowie im rechten Temporal-Pol und in der Vermis. Für rs220557 ergaben sich signifikante Effekte präzentral beidseits, links parietal und postzentral sowie im rechten MCC, im linken Precuneus, Cuneus und Gyrus angularis sowie in der Inselregion beidseits und im rechten Ncl. caudatus, parahippocampalen Gyrus, Hippocampus und Kleinhirn. Für beide SNPs ist davon auszugehen, dass die Risikoallelvarianten eine erhöhte Vulnerabilität für MDD hervorrufen.

description: This paper re-examines Lilien’s sectoral shifts hypothesis for U.S. unemployment. We employ a monthly
panel that spans from 1990:01 to 2011:12 for 48 U.S. states. Panel unit root tests that allow for crosssectional
dependence reveal the stationarity of unemployment. Within a framework that takes into account
dynamics, parameter heterogeneity and cross-sectional dependence in the panel, we show that sectoral
reallocation is significant not only at the aggregate level but also at the state level. The magnitude and the
statistical significance of the latter as measured by Lilien’s index increases when both heterogeneity and
cross-sectional dependence are taken into account.

Einen Zusammenhang zwischen dem Schmerzempfinden und den Wetterparametern Niederschlag, Luftdruck, Sonnenstunden und Bedeckungsgrad wurde festgestellt. Die Proband*innen haben täglich einen Fragebogen über einen Zeitraum von vier Wochen ausgefüllt. Zur Schmerzevaluation wurden der Western Ontario and McMaster Universities Osteoarthritis- Index (WOMAC) und die Visuelle Analog Skala (VAS) benutzt. Die verwendeten Wetterdaten stammten vom Deutschen Wetterdienst. Die vorliegenden Daten wiesen nach, dass hoher Luftdruck, wenig Niederschlag, viel Sonne und ein niedriger Bedeckungsgrad die Chance erhöhen, dass Patient*innen ihren Schmerz als unterdurchschnittlich intensiv wahrnehmen. Ein stärkerer Zusammenhang konnte zwischen hohem Niederschlag bzw. wenig Sonnenstunden und überdurchschnittlichem Schmerzempfinden gezeigt werden. Patient*innen, die Medikamente eingenommen haben, hatten die höchste Chance, ihre Schmerzen als überdurchschnittlich stark zu bewerten.

description: We study the Lemons Problem when workers have private information on both their skills and
their intrinsic motivation for the job offered by firms in the labor market.
We first show that, when workers are motivated, inefficiencies due to adverse selection are mitigated.
More interestingly, depending on the association between productivity and motivation, higher
salaries affect the pool of candidates in three possible ways: they can attract (i) more skilled but less
motivated applicants, as expected; (ii) more skilled and more motivated applicants; (iii) less skilled
and less motivated applicants. The last two counterintuitive effects can only occur when a positive
correlation exists between productivity and motivation.
Our results are relevant in the policy debate on whether it is possible to improve the quality
of workers in vocational markets by changing their wage rate and reconcile the different empirical
evidence provided so far on motivated workers such as public servants, teachers, health professionals
and, politicians.

description: Demographic change is expected to affect labour markets in very different ways on a regional scale. The objective of this paper is to explore the spatio-temporal patterns of recent distributional changes in the workers age structure, innovation output and skill composition for German regions by conducting an Exploratory Space-Time Data Analysis (ESTDA). Beside commonly used tools, we apply newly developed approaches which allow investigating the space-time dynamics of the spatial distributions. We include an analysis of the joint distributional dynamics of the patenting variable with the remaining interest variables. Overall, we find strong clustering tendencies for the demographic variables and innovation that constitute a great divide across German regions. The detected clusters partly evolve over time and suggest a demographic polarization trend among regions that may further reinforce the observed innovation divide in the future.

Studien zu Polysomnographien an Frühgeborenen und entsprechende Normwerte existieren bisher nicht. Das Ziel der vorliegenden Arbeit war daher die Bereitstellung repräsentativer Daten zum Respiratory Disturbance Index (RDI) sowie zum Verhalten der Sauerstoffsättigung (SaO2) in Polysomnographien von Frühgeborenen zum Zeitpunkt der Entlassung im Zeitraum von 2014 bis 2016. Zudem wurden potenzielle Einflussfaktoren wie das Gestationsalter, Geschlecht sowie pulmonale und zerebrale Schädigungen auf Zusammenhänge mit den Outcomeparametern geprüft. Die 106 eingeschlossenen Frühgeborenen unterliefen die Polysomnographie mit einem medianen postmenstruellen Alter von 38 + 6 Wochen. Der mediane RDI lag bei 28,6 Ereignissen/Stunde (Spannweite 1,5-182,3), die minimale Sauerstoffsättigung (minSaO2) betrug im Median 86% (Spannweite 62-99%). Das Geschlecht sowie die Dauer von Sauerstoffgabe und Beatmung hatten jeweils Einfluss auf die minSaO2 und SaO2-Abfälle < 90% (SaO2 < 90%). Der RDI stand mit keinem der Einflussfaktoren in Zusammenhang. Es wurden repräsentative Daten für den RDI und die SaO2 bei Frühgeborenen zum Zeitpunkt der Entlassung erhoben. Dabei ergeben sich Hinweise dafür, dass pulmonale Faktoren einen größeren Einfluss auf die respiratorische Stabilität haben als zerebrale Schädigungen. Die SaO2 erscheint hierbei als der sensitivere Parameter in der Bewertung der kardiorespiratorischen Stabilität im Vergleich zum RDI.

description: Empirical assessments of the forecasting power of spatial panel data econometric models are still scarcely available. Moreover, several methodological contributions rely on simulated data to showcase the potential of proposed methods. While simulations may be useful to evaluate the properties of a single estimator, the empirical set-ups of simulation studies are often based on strong assumptions regarding the shape and regularity of the statistical distribution of the variables involved. It is then valuable to have, next to simulation studies, empirical assessments of competing econometric models based on real data. In this paper, we evaluate competing spatial (dynamic) panel methods, selecting a number of data sets characterized by a range of different cross-sectional and temporal dimensions, as well as different levels of spatial auto-correlation. We carry out our empirical exercise on regional unemployment data for France, Spain and Switzerland. Additionally, we test different forecasting horizons, in order to investigate the speed of deterioration of forecasting quality. We compare two classes of methods: spatial vector autoregressive (SVAR) models and dynamic panel models making use of eigenvector spatial filtering (SF). We find that, as it could be expected, the unbalance between the temporal and cross-sectional dimension (T>>n) does play in favour of the SVAR model. On the other hand, the advantage of the SVAR model over the SF model appears to diminish as the forecasting horizon widens, eventually leading the SF model to being preferred for more distant forecasts.

description: Besides other Western nationalities, ‘Old Shanghai’ also hosted an Italian community, which experienced, throughout the years, a slight development, particularly after the establishment there of the consulate of the Kingdom of Sardinia in 1860 (later kept by the new Kingdom of Italy), and the signing, in 1866, of a Sino-Italian Treaty (ratified in Shanghai in 1867). It was a small group, if compared with the English, the Americans or the French (from some dozens to some hundreds between the 19th and the 20th centuries), but it had distinctive spatial and socio-economic urban patterns: in ‘Old Shanghai’, there were specific areas with a high concentration of Italian economic activities (in the International Settlement: Kiukiang Road; Kiangse Road; crossroads between Nanking Road and Szechuen Road; Bubbling Well Road), areas with Italian residences (French Concession), other suburban areas with Italians (Zikawei; in this case, they were priests). Moreover, Italians were involved in specific economic sectors (primarily, silk): as the textile sector was developed mainly in Lombardy at that time, most of the expatriate Italian managers and supervisors in Shanghai mills came from this Italian region. The migration flow from Italy to ‘Old Shanghai’, involving highly educated or highly skilled people mainly from Northern Italy, represented an exception in the general context of the migrations from Italy between the 19th and 20th centuries, which was mostly based, as in the case of the flow of people directed to the USA in that period, on poor and poorly educated people, originally involved in the primary sector, from the Southern regions of Italy.

description: Ziel der vorgelegten Dissertation ist es, herauszufinden, wann Patienten mit Ersatz des Knie- oder Hüftgelenks postoperativ das Autofahren wieder aufnehmen, und ob Faktoren wie operiertes Gelenk, die operierte Seite, das Geschlecht des Patienten, der Wohnort und die ärztlichen Empfehlungen einen Einfluss auf die postoperative Wiederaufnahme des Fahrens haben. Dazu wurde eine einarmige monozentrische, experimentelle, prospektive Beobachtungsstudie aus der Perspektive der rehabilitativen orthopädischen Therapie konzipiert und durchgeführt. Wesentliche Ergebnisse dieser Studie sind die Darstellung signifikanter Unterschiede bei der Wiederaufnahme des postoperativen Autofahrens hinsichtlich Geschlecht, Wohnsitz, Seite des Eingriffs bei Knie-TEP und die Identifikation von Risikogruppen.

description: Policy interventions aimed at affecting a specific behavior may also indirectly affect individual choices in other domains. In this paper we study the direct effect of tobacco excise taxes and smoking bans on smoking behavior, and the indirect effect on eating behavior and body weight. Using very detailed clinical data on individual health, smoking, and dietary habits, we show that antismoking policies are effective in reducing smoking, but their consequences on eating behavior dramatically depend on the specific implemented policy. Increasing excise taxes on tobacco decreases body weight and caloric intake, and it improves the quality of eaten food. Smoking bans, instead, do not significantly affect body weight, although they impact on the diet composition. Smoking bans in restaurants induce a significant rise in the quality of food and in daily caloric intake. Conversely, smoking bans in bars negatively affect the quality of the daily diet, as individuals eat more fats and less fibers, and drink more alcohol and caffeine.

description: We present the stability analysis of the dark states in the adiabatic passage for the linear and non-linear lambda and tripod systems in the presence of amplitude damping (losses). We perform an analytic evaluation of the real parts of eigenvalues of the corresponding Jacobians, the non-zero eigenvalues of which are found from the quadratic characteristic equations, as well as by the corresponding numerical simulations. For non-linear systems, we evaluate the Jacobians at the dark states. Similarly to the linear systems, here we also find the non-zero eigenvalues from the characteristic quadratic equations. We reveal a common property of all the considered systems showing that the evolution of the real parts of eigenvalues can be split into three stages. In each of them the evolution of the stimulated Raman adiabatic passage (STIRAP) is characterized by different effective dimension. This results in a possible adiabatic reduction of one or two degrees of freedom.

description: Die Ätiologie autoimmuner Arthritiden ist unklar. Humane endogene Retroviren (HERV) und Superantigene (SAg) könnten bei der Entstehung eine Rolle spielen. Zuletzt wurde als eine Erklärung die Superantigen-Arthritis als Tiermodell entwickelt. Die vorliegende Arbeit greift dieses Modell und die HERV/SAg-Theorie auf. Es erfolgte eine immunhistochemische Untersuchung von Kniegelenken der Lewis-Ratte nach intraarktikulärer Injektion des Glykoproteins 120. Dies ist ein virales Superantigen, welches hier anstelle eines HERV-kodierten Proteins steht. Bei der immunhistochemischen Untersuchung wurden T- und B-Zell-Marker sowie MHC-Marker verwendet. Die Untersuchung der Oberflächenantigene erfolgte zu fünf verschiedenen Zeitpunkten nach intraartikulärer Injektion. Bei der Auswertung zeigte sich in den mit SAg behandelten Tieren eine Arthritis. Die synoviale Entzündungsreaktion war durch CD8+-Zellen dominiert und auf den oberen Recessus des Kniegelenks konzentriert.
description: The etiology of autoimmune arthritides is unclear. Human endogenous retroviruses (HERV) and superantigens (SAg) may play a role in the development. Most recently, superantigen arthritis has been developed as an animal model as one explanation. The present work takes up this model and the HERV/SAg theory. Immunohistochemical examination of Lewis rat knee joints was performed after intraarcticular injection of glycoprotein 120, which is a viral superantigen that is substituted here for a HERV-encoded protein. T-cell and B-cell markers as well as MHC markers were used in the immunohistochemical study. The examination of surface antigens was performed at five different time points after intra-articular injection. On evaluation, arthritis was evident in the SAg-treated animals. The synovial inflammatory response was dominated by CD8+ cells and concentrated in the superior recess of the knee joint.
