description: We study the rate of convergence for the largest eigenvalue distributions in the Gaussian unitary and orthogonal ensembles to their Tracy-Widom limits. We show that one can achieve an $O(N^{-2/3})$ rate with particular choices of the centering and scaling constants. The arguments here also shed light on more complicated cases of Laguerre and Jacobi ensembles, in both unitary and orthogonal versions. Numerical work shows that the suggested constants yield reasonable approximations, even for surprisingly small values of N.

description: This thesis examines how dashcam videos can be used to understand different road events and driving behaviors. It introduces practical solutions by developing an advanced AI model to analyze and describe these videos. The model combines visual and language information, allowing it to process and explain what is happening in the videos efficiently. Using cutting-edge AI technology, this model can accurately interpret and describe the events captured by dashcams. This research highlights how dashcam videos and intelligent AI systems can be used to enhance road safety.

An even less convenient truth : addressing the challenge of sustainable development through an integration of cognition and culture
Creators: name: Levine, Jordan
Publisher: name: University of British Columbia
Year: 2014

description: ‘Sustainable development,’ or how to achieve durably desirable states in our planet’s nested social-ecological systems, has been heralded by many as the core civilizational challenge of the 21st century. Adding to this challenge is the fact that the scientific study of how to model and manage such complex systems is confounded by a number of archaic intellectual legacies from predecessor disciplines. Chief among these is a relatively crude, low-resolution ‘rational actor’ theory of human behaviour, which lies in tension with a range of more recent, empirical insights regarding how humans absorb information, make decisions, and act, in situ. I argue that, while authors widely acknowledge the former theory to be insufficient, terminological inconsistencies and conceptual opacity have prevented the latter insights from being fully integrated into much sustainable development research. This dissertation aims to help bridge that gap on the level of both theory and practice. First, I present an accessible, original synthesis of cumulative recent findings on human cognition. This synthesis suggests a key object of analysis should be the particular ways in which people reduce the deep complexity of their social-ecological context into actionable information. I then apply this theoretical lens to the study of two areas designated by the UN as sites for experimentation with the concept of sustainable development: Mt. Carmel UNESCO Biosphere Reserve in Israel, and Clayoquot Sound UNESCO Biosphere Reserve in British Columbia, Canada. Both Mt. Carmel and Clayoquot Sound are reeling from major ecological shifts, and discordant multistakeholder relations. In my data chapters, I show that by (a) applying my synthesized theoretical lens to an analysis of how the various stakeholders perceive their local context, and (b) adapting and combining a range of elicitation and analysis methods that heretofore have been applied in isolation, I am able to generate insights that have direct, actionable significance for the management of these sensitive, politically fraught social-ecological systems. I conclude with a discussion of implications, caveats, prospects of scalability, and suggestions for future research.

description: Tätigkeitsbezogene Kooperation und Kommunikation (KoopKomm) ist eine gängige Anforderung an Beschäftigte im Rahmen ihrer Tätigkeiten sowie zugleich Erfassungsgegenstand zahlreicher Verfahren zur psychischen Gefährdungsanalyse. Zur Beanspruchungswirkung dieses Arbeitsmerkmals fehlen jedoch empirische Studien. Die vorliegende Arbeit betrachtet den Zusammenhang von KoopKomm mit mittelfristigen Fehlbeanspruchungsfolgen an einer berufstätigen Stichprobe. Die Erhebung von KoopKomm erfolgte dabei durch Fragebögen und durch Schichtbeobachtungen. Zwei Facetten von KoopKomm – das Vorliegen von Koop-Erschwernissen und das Erleben einer niedrigen KoopKomm-Qualität – stehen mit Fehlbeanspruchungsfolgen in Zusammenhang (u.a. Depressivität und vitale Erschöpfung). Die tätigkeitsbedingten KoopKomm-Erfordernisse allein weisen keinen Zusammenhang zu den betrachteten Fehlbeanspruchungsfolgen auf. Die Ergebnisse werden vor dem Hintergrund ihrer Bedeutung für die Durchführung von betrieblichen Gefährdungsanalysen psychischer Belastungen und der anschließenden Ableitung von Arbeitsgestaltungsmaßnahmen diskutiert.
description: Work-related cooperation and communication (coopcomm) is a common demand on employees in the context of their routine activities, while at the same time, it is frequently a central topic in psychological risk analysis inventories. However, empirical studies on the impact of this occupational characteristic are lacking. This thesis examines the relationship between coopcomm and medium-term psychological strain in a population of working individuals. Coopcomm was investigated by means of questionnaires as well as observational studies. Two aspects of coopcomm – the presence of coop-hindrances and the experience of a low coopcomm quality – were related to psychological strain, e.g., depressiveness and vital exhaustion. The work-related demand for coopcomm alone did not exhibit a relationship with the employee strain under investigation. The results are discussed in light of their relevance in the application of occupational risk analyses and the derivation of work design policies.

description: Abstract: In the last decade, Italy has experienced a convergence of regional nominal interest rates on current accounts and short-term credit, whereas the convergence of real rates has been much weaker. In a risk-sharing perspective, however, these outcomes allow for a high degree of neutralization of idiosyncratic shocks on regional consumption.

description: In dieser Arbeit wurden BiFeO3 (BFO)-Filme mittels gepulster Laserabscheidung epitaktisch auf SrTiO3- und REScO3 (RE = Dy, Gd, Sm)-Substraten aufgewachsen, die teilweise vorher mit einer leitfähigen SrRuO3 beschichtet wurden. Der Einfluss der verschiedenen Randbedingungen auf die ferroelektrischen/ferroelastischen Domänenbildung in den BFO-Filmen wurde mit Röntgendiffraktometrie, Transmissionselektronenmikroskopie und Piezoresponse-Rasterkraftmikroskopie charakterisiert. Des Weiteren wurde das ferroelektrische Schalten von 71°-Streifendomänen untersucht. Die Netto-Polarisierung der Streifendomänen konnte in der Filmebene stabil und reproduzierbar geschaltet werden. Beim Schalten senkrecht zur Filmebene wurde hingegeben ein Übergang zu einer neuen Domänenkonfiguration beobachtet, welche von der angelegten Schaltfrequenz abhing. Im letzten Teil der Arbeit wurde das differenzielle Ätzen von BFO-Schichten untersucht, welches die Herstellung epitaktischer Strukturen unterhalb eines Mikrometers erlaubt.
description: In this work epitaxial BiFeO3 (BFO) thin films were grown by pulsed laser deposition on SrTiO3 and REScO3 (RE = Dy, Gd, Sm) substrates, partly covered by a conductive SrRuO3 bottom electrode. The influence of the various boundary condition on the ferroelectric/ferroelastic domain formation in the BFO films was characterized by X-ray diffraction, transmission electron microscopy and piezoresponse force microscopy. Furthermore, the ferroelectric switching behaviour of 71° stripe domains was investigated. The net polarization could be switched stable and reproducible in-plane, however, for out-of-plane switching a transition to a new domain state occurred, which depended on the applied switching frequency. In the last part of the work the differential etching of BFO thin films was studied, which allowed the fabrication of submicron epitaxial structures.

description: The bipolarity of Supernova 1987A can be understood through its very early light curve observed from the CTIO 0.4-m telescope and IUE FES, and following speckle observations of the `Mystery Spot' by two groups. These indicate a highly directional beam/jet of light/particles, with initial collimation factors in excess of 10,000 and velocities in excess of 0.95 c, as an impulsive event of up to 1e-5 solar masses interacting with circumstellar material. These can be produced by a model proposed in 1972, by Bolotovskii and Ginzburg, which employs pulsar emission from polarization currents induced/(modulated faster than c) beyond the pulsar light cylinder by the periodic electromagnetic field (supraluminally induced polarization currents -- SLIP). SLIP accounts for the disruption of progenitors in supernova explosions and their anomalous dimming at cosmological distances, jets from Sco X-1 and SS 433, the lack/presence of intermittent pulsations from the high/low luminosity low mass X-ray binaries, long/short gamma-ray bursts and predicts that their afterglows are the pulsed optical/near infrared emission associated with these pulsars. SLIP may also account for the TeV e+/e- results from PAMELA and ATIC, the WMAP `Haze'/Fermi `Bubbles', and the r-process. SLIP jets from SNe of the first stars may allow galaxies to form without dark matter, and explain the peculiar, non-gravitational motions observed from pairs of distant galaxies by GALEX.

description: The aim of the paper is to identify the different role of the financial funds of R&D investments in
the Italian firms. The dataset used for this study is the Survey of Italian Firms conducted by the
SME Observatory run by the Capitalia Research Division. R&D is defined as a creative activity
implemented to improve knoweledge and its use in new applications. Given its intrisic
characteristics, R&D is usually characterizedby high information opacity that choerently with the
theory of asymmetric information implies more difficulties in finding external financial funds. The
greater riskiness on R&D projects could imply banks to some forms of credit rationing. Signalling
mechanisms like as self-financing could, however, to correct this market imperfection. In this study
we propose a self-selection model in wich the internal (i.e. informed) capital is the way by which
the firms signal to the external borrowers the quality of their investment project. The aim of the
research is to investigate the determinants of R&D investments financial funds. Moreover, we focus
our attention on the estimate of the internal capital compared to the other financial funds.

description: Aufgrund der erwarteten positiven Auswirkungen auf die Leistung der Beschäftigten, wird die Methode des Führens durch Ziele in einem Großteil der deutschen Unternehmen angewandt. Befragungen weisen jedoch darauf hin, dass das Führen durch Ziele auch mit negativen Auswirkungen in Verbindung gebracht werden kann. In der Arbeit wird zunächst die problematische Anwendung der Vorgabe von schwierigen und spezifischen Leistungszielen in der Praxis hinterfragt, indem Problemstellen durch arbeitspsychologische Modelle aufgezeigt werden. Anschließend werden diese Annahmen empirisch geprüft und Ansatzpunkte für eine integrative Umsetzung der Erkenntnisse in die Praxis gegeben. Werden in Unternehmen Leistungsziele ohne Berücksichtigung der Leistungsvoraussetzungen der Beschäftigten abgeleitet, sind Fehlbeanspruchungen nicht auszuschließen - folglich widerspricht die Umsetzung des Führens durch Ziele in vielen deutschen Unternehmen, den Forderungen des Arbeitsschutzgesetzes.
description: Management by objectives is widely-spread as many companies anticipate a positive effect on performance. However, in surveys, management by objectives is described as a source for high workload, which in turn leads to stress-associated illness. In this dissertation, the practice of difficult and specific performance goals is scrutinized. Potentially problematic issues are addressed by work psychological concepts. Hypotheses are tested empirically and lead to criteria for an integrative design of management by objectives. If performance goals are derived from company goals without taking individual performance requisites into account, negative effects on mental strain cannot be ruled out. Thus, if not executed properly, modern practice of management by objectives violates work safety laws.

description: We study constant mean curvature 1/2 surfaces in H2xR that admit a compactification of the mean curvature operator. We show that a particular family of complete entire graphs over H2 admits a structure of infinite dimensional manifold with local control on the behaviors at infinity. These graphs also appear to have a half-space property and we deduce a uniqueness result at infinity. Deforming non degenerate constant mean curvature 1/2 annuli, we provide a large class of (non rotational) examples and construct (possibly embedded) annuli without axis, i.e. with two vertical, asymptotically rotational, non aligned ends.

description: This paper sets out to analyse the determinants of Italian SMEs’ choices of
sources of finance, with specific reference to the role of informed (internal)
capital compared to other forms of finance. In this work, we aim to identify
the determinants of the mix of sources of finance using data from the
Survey of Italian Firms conducted by Capitalia, bearing in mind the
structural characteristics of the firms and the banking market, and the
problems of the information asymmetry between the bank and the firm.
Although the financial hierarchy theory suggests that firms prefer selffinancing,
because it is less expensive in economic terms, relationships with
local banks may offer advantages which encourage firms to enter into debt
contracts even in the absence of binding internal constraints. The empirical
study focused in particular on the role of self-financing as an alternative to
external sources. In order to measure the decision to use self-financing and
the subsequent composition of the financing mix, we used different
techniques, first independent models and then a self-selection model. The
first results, in line with the pecking order theory, confirm an approach
comprising an initial check on the availability of internal resources,
followed if by the use of external capital, including bank debt.

A Tannakian Context for Galois

description: Strong similarities have been long observed between the Galois (Categories Galoisiennes) and the Tannaka (Categories Tannakiennes) theories of representation of groups. In this paper we construct an explicit (neutral) Tannakian context for the Galois theory of atomic topoi, and prove the equivalence between its fundamental theorems. Since the theorem is known for the Galois context, this yields, in particular, a proof of the fundamental (recognition) theorem for a new Tannakian context. This example is different from the additive cases or their generalization, where the theorem is known to hold, and where the unit of the tensor product is always an object of finite presentation, which is not the case in our context.
description: This is a revision. We switch some of the proofs to another level of abstraction. We generalized the equivalence between the Tannaka and the Galois recognition theorems from atomic to arbritrary topoi. We strengthened the result "The Tannaka lifting functor is an equivalence" for atomic topos to "The Tannaka lifting functor is an equivalence if and only if the topos is atomic"

description: This exposition presents a self-contained proof of the $A_2$ theorem, the quantitatively sharp norm inequality for singular integral operators in the weighted space $L^2(w)$. The strategy of the proof is a streamlined version of the author's original one, based on a probabilistic Dyadic Representation Theorem for singular integral operators. While more recent non-probabilistic approaches are also available now, the probabilistic method provides additional structural information, which has independent interest and other applications. The presentation emphasizes connections to the David-Journé $T(1)$ theorem, whose proof is obtained as a byproduct. Only very basic Probability is used; in particular, the conditional probabilities of the original proof are completely avoided.

description: Einleitung und Zielstellung: Karies, parodontale Erkrankungen und Periimplantitis verursacht durch einen schlechten Randschluss von festsitzenden Restaurationen sind Gründe für den klinischen Funktionsverlust von kombiniert zahn-implantatgetragenen Verbundbrücken (TISFDP). Diese In-vitro-Studie untersuchte mögliche Veränderungen des Randspaltes an natürlichen Zähnen und Implantaten innerhalb von Verbundbrücken nach der Zementierung und nach Langzeitbelastung in Abhängigkeit von der Zementart um herauszufinden, ob die Verbundbrücke ein erhöhtes Risiko für Randspalt-veränderungen unter Funktion birgt. Material und Methode: Die Testgruppe (TG) bestand aus 12 dreigliedrigen TISFDPs aus einer hochgoldhaltigen Legierung. Jede TISFDP bestand aus einem humanen Oberkieferprämolaren mit einem künstlichen Parodontium und einem Implantat. Als Vergleichsgruppe (VG) dienten 4 dreigliedrige rein zahngetragene konventionelle Brücken (TSFDP) ebenfalls mit künstlichen Parodontium ausgestattet. Die TG (jeweils 4) wurde mit 3 verschiedenen Zementen befestigt: Zinkoxidphosphat, Glasionomer, selbstadhäsives Komposit (VG: Zinkoxidphosphat). Die Modelle wurden mechanisch (1,2Mill.Zyklen /50N) und thermisch (8000 Zyklen, 5/55°C) belastet. Die senkrechte Randspalthöhe wurde vor und nach der Zementierung, nach der mechanischen und nach der thermischen Belastung mittels lichtmikroskopischer Vermessung ermittelt (x560). Die Ergebnisse statistisch ausgewertet (t-Test/Anova/Bonferroni). Ergebnisse: Die Zementierung ergab eine signifikante Randspalterhöhung (p≤0,05) in der TG (Implantat 11,7–18,7µm, Zahn 13,4-28,5µm) und VG (28,5µm). Die mechanische und thermische Belastung brachten keine signifikanten Änderungen (p≥0,05) des Randspaltes in TG und VG hervor. Schlussfolgerung: Die Zementierung führte zu signifikanten Randspalterhöhungen in der TG und VG sowohl am Zahn als auch am Implantat. Trotz der Mobilitätsunterschiede innerhalb von TISFDP ergaben sich keine signifikanten Randspaltänderungen durch mechanische und thermische Belastung. Im Vergleich zur TSFDP weist die TISFDP kein erhöhtes Risiko für marginale Integrität unter Funktion bzw. für randspaltassoziierte Erkrankungen auf. Ein Einfluss der Zementart wurde nicht festgestellt.

Phosphoinositides modulate auxin-dependent transcription by controlling the histone acetyltransferase GCN5 in Arabidopsis

description: Phosphoinositide (PIs) kommen in eukaryotischen Membranen vor. In Pflanzen sind PIs Regulatoren des zytoplasmatischen Membranverkehrs und des Zytoskeletts. Die Arabidopsis PI-Kinase PIP5K2 lokalisiert im Zellkern und an der Plasmamembran. Bei veränderter Expression von PIP5K2 wurden in Arabidopsis reduzierte oder erhöhte Histon-Acetylierung detektiert. Interaktionstests zwischen PIP5K2 und Histon-modifizierenden Enzymen zeigten eine Interaktion mit der Histon-Acetyltransferase GCN5. Überexpression von PIP5K2 in Protoplasten schwächte die Auxin-vermittelte Aktivierung GCN5-abhängiger Gene ab, was mit verminderter H3-Acetylierung konsistent ist. In vitro hemmten PIs die H3-Acetylierung durch GCN5, was auf einen direkten Einfluss von PIs auf GCN5 hinweist. Eine PI-Bindung von GCN5, speziell an PtdIns3P, die für die nukleäre Lokalisierung von GCN5 erforderlich schien, konnte bestätigt werden. Die Daten weisen darauf hin, dass GCN5 durch PtdIns3P an aktive Transkriptionsstellen rekrutiert werden könnte. PIP5K2 entfernt möglicherweise PtdIns-monophosphate aus dieser Interaktion und beeinflusst so die Transkription.
description: Phosphoinositides (PIs) occur in eukaryotic membranes. In plants, PIs are regulators of cytoplasmic membrane trafficking and cytoskeleton. The Arabidopsis PI-kinase PIP5K2 localizes in the nucleus and at the plasma membrane. Upon changed expression of PIP5K2, reduced or increased degrees of histone acetylation were detected in Arabidopsis. Interaction assays between PIP5K2 and histone-modifying enzymes revealed an interaction with the histone acetyltransferase GCN5. Overexpression of PIP5K2 in protoplasts attenuated auxin-mediated activation of GCN5-dependent genes, consistent with decreased H3 acetylation. In vitro, PIs inhibited H3 acetylation by GCN5, indicating a direct effect of PIs on GCN5. PI binding of GCN5, especially to PtdIns3P, that was required for nuclear localization of GCN5, could be confirmed. The data suggest that GCN5 may be recruited by PtdIns3P to active transcription sites. PIP5K2 may remove PtdIns-monophosphates from this interaction and thus affects transcription.

description: In der vorliegenden Arbeit wurde untersucht, ob sich bei Rehabilitanden mit degenerativen und unspezifischen Rückenerkrankungen geschlechtsspezifische Unterschiede im Verlauf während und nach einer stationären medizinischen Reha-Maßnahme ergeben. Hierzu wurden Daten einer früheren Verlaufsstudie der Sektion Medizinische Soziologie, in der 316 Rehabilitanden (194 Männer, 122 Frauen) mit den Reha-Indikationen M47, M48, M50, M51, M53, M54 (ICD-10) u.a. zu zahlreichen reharelevanten Merkmalen befragt worden waren (standardisierter Fragebogen, u.a. IRES-MIN, FFbH-R, BSI, FEBA-B) genderbezogen ausgewertet (3 Erhebungszeitpunkte: T1 = Reha-Beginn, T2 = Reha-Ende, T3 = 6 Monate nach Reha-Ende). Es zeigten sich nur bei einigen Merkmalen relevante geschlechtsspezifische Unterschiede (z.B. bei Funktionseinschränkungen, zum Teil bei erwerbsbezogenen Merkmalen). Überwiegend fanden sich bei Männern und Frauen vergleichbare Veränderungen während und nach der Reha. Bei beiden Geschlechtern kam es während der Reha zu einer Zustandsverbesserung bei den meisten untersuchten Indikatoren zum körperlichen und psychischen Befinden sowie bei den Schmerzmitteilungen, jedoch bauten sich die Reha-Erfolge in den 6 Monaten nach der Maßnahme zumeist wieder ab – bei Männern etwas deutlicher als bei Frauen. Die Entwicklung bzw. Optimierung von Strategien zur Verstetigung der positiven Effekte stationärer Reha-Maßnahmen erscheint für Männer wie Frauen gleichermaßen erforderlich.

description: In this paper we prove that the support of a random measure on the unit ball of a separable Hilbert space that satisfies the Ghirlanda-Guerra identities must be ultrametric with probability one. This implies the Parisi ultrametricity conjecture in mean-field spin glass models, such as the Sherrington-Kirkpatrick and mixed $p$-spin models, for which Gibbs' measures are known to satisfy the Ghirlanda-Guerra identities in the thermodynamic limit.

description: Meeting the fundamental science goals put forward in the ALMA Development Roadmap requires a series of dramatic upgrades to the telescope throughout the signal chain, and users will begin to see these upgrades in the next few years. In this poster, we demonstrate the capabilities specifically enabled by the Wideband Sensitivity Upgrade (WSU) with several science use cases, as well as aspects of these new technologies which will likely have the highest impact on science observing from a PI's perspective. In particular, we introduce the spectral resolution and available instantaneous bandwidth which will be enabled by the Advanced Technology ALMA Correlator (ATAC), and we highlight the improvements coming to three of the first receiver bands to be upgraded (Bands 2, 6, and 8).

description: Objectives: In the past four decades, the median age of survival has nearly doubled for individuals with cystic fibrosis (CF), where over half the population is now adults. The prevalence of chronic diseases such as chronic rhinosinusitis (CRS) has increased with older age. In the non-CF population, CRS is associated with reduced health-related quality of life (HRQoL). Our objectives were to determine the prevalence of CRS among adults with CF and evaluate its impact on their HRQoL. Methods: One hundred sixty individuals from an academic teaching hospital in Vancouver, Canada were eligible to participate in this cross-sectional study. Included subjects were above the age of 18 years, had a confirmed diagnosis of CF and attended the CF clinic between September 2013 and April 2014. Participants completed a CF-specific HRQoL questionnaire (i.e. CFQ-R 14+), and underwent symptom and endoscopic assessment to diagnose CRS. Medical charts were reviewed for potential confounders that included socio-demographic (age, gender and body-mass index) and clinical factors (age of CF diagnosis, type of CF mutation, lung function and chronic Pseudomonas aeruginosa infection). Multivariable linear regression was used to model the relationship between CRS and HRQoL, adjusted for potential confounders. Results: One hundred twenty-one individuals were contacted prior to clinic visits of which, 113 (93.4%) consented to participate. The prevalence of CRS was found to be 64.2%. Socio-demographic and clinical factors were similarly distributed between CRS-positive and negative groups, except age of CF diagnosis. CRS-positive individuals were diagnosed with CF at younger age than non-CRS counterparts, although this finding was not significant (mean difference: 6.5 years, p=0.13). In unadjusted analysis, those with CRS reported worse HRQoL on 10 of 12 domains of the CFQ-R 14+. These findings remained despite adjustment for potential confounders. Individuals with CRS reported significantly worse HRQoL on Respiratory symptoms (adjusted regression coefficient: -13.33, p=0.001) and Digestion (adjusted regression coefficient: -8.71, p=0.03) domains, than non-CRS counterparts. Conclusion: The majority of adults with CF suffer from concomitant CRS. CRS is associated with worse HRQoL based on multiple domains of the CFQ-R 14+. CRS should be diagnosed and managed to optimize the HRQoL for adults with CF.

description: In der Strahlentherapie von Patienten mit metallischen Implantaten, wie z.B. Hüft- oder Knie-Endoprothesen wurde festgestellt, dass Gewebe in der Umgebung der Prothesen durch die an den Metalloberflächen zusätzlich auftretende Streustrahlung häufig ausgeprägtere Schädigungen zeigt, als Gewebe ohne direkten örtlichen Bezug zu Implantaten. Ziel dieser Arbeit war es, diese Beobachtung für den Bereich der Zahnmedizin zu untersuchen und einen möglichen Einfluss verschiedener Restaurationsmaterialien auf die Entstehung von Karies an bestrahltem humanen Schmelz und Dentin nachzuweisen. Es wurden 32 menschliche dritte Molaren mit den vier in der Zahnmedizin am häufigsten verwendeten Füllungswerkstoffen (Goldlegierung, Amalgam, Dentalkeramik und Kunststoffkomposit) versorgt und jeweils eine Hälfte einer tumortherapeutischen Strahlung einer Gesamtdosis von 60 Gy ausgesetzt. Anschließend wurde mit angesäuerter Hydroxyethylcellulose artifiziell Karies erzeugt. Die Auswertung der Demineralisationstiefen erfolgte an Dünnschliffen im Polarisationsmikroskop. Verglichen wurde hierbei, ob es bei den bestrahlten Proben in Abhängigkeit des Füllungswerkstoffes zu ausgeprägterer Demineralisation kam. Die mit Amalgam versorgten Zähne zeigten hochsignifikant tiefere Läsionen. In den anderen Gruppen hatte die Bestrahlung keinen hochsignifikanten Einfluss auf die Demineralisationstiefen. Die Ergebnisse führen zur Schlussfolgerung, dass die Wahl des Restaurationsmaterials einen gewissen Einfluss auf die Entstehung von Karies an bestrahltem Schmelz und Dentin ausüben kann. Die Auswirkungen der Strahlung auf die Zahnhartsubstanzen, beeinflusst von der Anwesenheit eines bestimmten Restaurationsmaterials, kann eine Ursache für die erhöhte Kariesanfälligkeit sein.

description: This paper provides an analytical model representing four polar ethical approaches, by linking them to the main ethics suggested by the philosophical, psychological, and socio-economic literature. Moreover, it develops the analytical model in order to obtain rankings of the 4 polar ethical approaches in terms of happiness and, consequently, to provide insights on which ethical approach should be adopted by each individual, according to his characteristics (income level, in DCs or in LDCs, aspiration level): some dynamics are predicted, if the Golden and the Copper rules are applied. Finally, this paper provides insights on which ethical approach should be adopted by each society, according to its characteristics (DCs or LDCs, social distribution of aspiration levels), by predicting happiness levels in alternative countries, according to the prevailing ethics, and by comparing these predictions with the observed happiness levels, in order to provide an empirical test of the analytical model: some dynamics are predicted, with non-Protestant DCs moving to higher, and Protestant DCs towards lower, happiness levels (conditioned to the per capita income), due to the increasing and decreasing rejection of the Golden and Copper rules, respectively, and with LDCs moving to lower (conditioned to the increasing per capita income) in the short-run and higher happiness levels in the long run, by establishing and entertaining conditions that set clear incentives for moral behaviour, in order to increase and decrease the adoption of the Golden and Copper rules, respectively

description: Auf der Suche nach einem bioresorbierbaren Klebstoff zur Frakturversorgung bis heute ist kein optimales Adhäsivmaterial gefunden, das den Anforderungen bezüglich Biokompatibilität, Resorbierbarkeit, adhäsiver Fähigkeiten und mechanischer Eigenschaften genügt. In dieser In-vitro-Studie wurde der Einfluss unterschiedlicher Oberflächenvorbehandlungen auf die Haftkraft zwischen kortikalem Schweineknochen und Komposit unter Verwendung des Dentinhaftvermittlers Clearfil™ New Bond ermittelt. Die Ergebnisse der Studie zeigen, dass mit steigender Rauheit der Knochenoberfläche die Festigkeit der Bindung Knochen-Adhäsiv ansteigt und mit längerer Ätzzeit die Festigkeit gegenüber Zug zunimmt. Gegenstand aktueller Forschungen sind die mechanischen Eigenschaften und die Biokompatibilität möglicher Adhäsivsysteme. Defizite an Erkenntnissen bezüglich des Einflusses der Oberflächenvorbehandlung wurden beklagt. Mit dieser Studie wird diese Lücke in der Grundlagenforschung ein Stück weiter geschlossen.
description: Until now, no ideal degradable fibre could be found for the treatment of midfacial fractures when it comes to biocompatibility, degradability, adhesive ability and mechanical characteristics. This in-vitro study tested the influence of different surface pretreatments on the tensile bond strength between porcine cortical bone and composite material while using the dentin adhesive system Clearfil™ New Bond. The results of this study indicate that the tensile strength between bone and adhesive increases with a rougher bone surface and longer acid-treatment. Mechanical characteristics and biocompatibility of possible adhesive systems are subject of current research, yet there is a lack of knowledge about the influence of surface pre-treatment on the adhesive strength.This study closes this gap in basic research a little further.

description: Ziel dieser tierexperimentellen Arbeit war der direkte Vergleich der Knochenheilung und Biokompatibilität zweier unterschiedlicher Knochenkleber in einem standardisierten Osteotomiemodell an der Kaninchenkalotte. Die beiden Knochenklebervarianten waren ein auf Bis-GMA basierender Dentinhaftvermittler (DHV) und ein Gewebekleber aus N-Buty-2-Cyanoacrylat. Insgesamt wurden 30 Tiere untersucht und in 3 Gruppen (Titan-Kontrolle, DHV, Gewebekleber) eingeteilt. Als histomorphometrische Parameter wurden Knochenneubildung und Knochenmineralisation bestimmt. Außerdem wurden weitere histologische, klinische und röntgenologische Untersuchungen durchgeführt. Die Klebervariante mit DHV zeigte anhand der histomorphometrischen Auswertung keine Barriere für die physiologische Frakturheilung, im Gegenteil, es fand sich eine hervorragende Osteogenese im Frakturspalt. Beide Kleber ermöglichten vergleichbare oder bessere Ergebnisse bezüglich Frakturheilung und Knocheneubildung im Vergleich zur Kontrollgruppe zu allen Zeitpunkten. Die Ergebnisse zeigten signifikante Unterschiede zwischen der Klebervarianten und der Titanosteosynthese als Kontrolle.
