description: Innovation has an increasing role in the economic progress of China. With Chinese patent applications surpassing those of Western countries, we aim to understand what is the actual perception and understanding of the value and importance of intellectual property (IP)on the ground in China. This paper reports insights from a field trip across 3key innovation clusters in China (Beijing, Shenzhen and Shanghai). We conduct an ethnographic studyusing20semi-structuredinterviews with academics and researchers, representatives from enterprises and economic service firms as well as university leaders and policy makers. The results reveal a high level of IP awareness in China. Whether academics, governmental representatives, entrepreneurs or venture capital executives, all interviews reveal a strong understanding and visibility of the importance of IP. Governmental rules for subsidizing patent applications seems to be changing in China in order to move from quantity to quality. While at least the leading universities have established technology transfer offices (TTOs), there still a need for improve service offerings given that these are still offered by IP law firms. Moreover, leading universities offer occasional IP guest lectures and they are in the process of installing IP. In addition, investors seem to understand the importance of IP when making investment decisions. We identify a positive speed of which Chinese innovation system actors are becoming increasingly IP savvy. At the same time, China’s large market size makes it less attractive to consider international IP strategies in early stages of a business. After succeeding in China, companies tend to prefer expanding into other Asian markets first, before venturing into Europe or the US.

description: A GaAs monolithic clock and data recovery circuit for 2.5 Gb/s NRZ data stream has been designed and fabricated by using 0.3 mm HEMT technology from IAF FhG foundry. The main functions carried out by the IC are: signal amplification (25 dB), clock recovery and decision. The design is intended to achieve a complete 2.5 Gb/s receiver by using the IC and a LN preamplifier (transimpedance stage and limiting amplifier stage) placed in a DIL package. The overall scheme comprises about 200 active devices, used both for analog and digital blocks, uses a single rail bias (-4.5 V) and standard ECL output levels. The fabricated chip has been tested and measured by using a ceramic package and a small PCB, showing an input sensitivity of 30 mVpp and rms output jitter below 10 psec under 215-1 PRBS.

description: We analyze the behavior of a relativistic particle moving under the influence of a uniform magnetic field and a stationary electrostatic wave. We work with a set of pulsed waves that allows us to obtain an exact map for the system. We also use a method of control for near-integrable Hamiltonians that consists in the addition of a small and simple control term to the system. This control term creates invariant tori in phase space that prevent chaos from spreading to large regions and make the controlled dynamics more regular. We show numerically that the control term just slightly modifies the system but is able to drastically reduce chaos with a low additional cost of energy. Moreover, we discuss how the control of chaos and the consequent recovery of regular trajectories in phase space are useful to improve regular particle acceleration.

description: Although data visualisation approaches have been extensively discussed in the literature, most visualisation tools are associated with quantitative data and lack the compound ability to collect data. The author’s PhD research needs a data collection tool that has the ability to present qualitative data on how and why companies change their intellectual property (IP) strategies and to allow visualisation of the companies’ IP strategy trajectories. Hence, in this paper, the authors created a bespoke set of tools, consisting of the IP strategy trajectory framework and the IP strategy trajectory map. With exercising this new approach with the data of a case study, the authors show that the framework offers a clear presentation of the path that a company takes with regards to its IP strategy openness, whereas the map help explain how and why a company change its IP strategy during three key transitions. The paper contributes theoretically by offering a definition for intellectual property strategy trajectory and contributes practically by creating a new visualisation approach which consists of the IP strategy trajectory framework and the IP strategy trajectory map.

description: Ziel dieser Studie war es, die apikale Dichtigkeit von unterschiedlichen Obturationstechniken (Laterale Kondensation, Zentralstifttechnik, Vertikale Kondensation, Thermafil®) unter Verwendung der Sealer AH Plus® und EndoREZ® zu untersuchen. Material und Methode: Dazu wurden 216 humane Zähne unter standardisierten Bedingungen aufbereitet. Die Zähne wurden in die Hauptgruppen A (AH Plus®) und B (EndoREZ®) zu je 108 Proben aufgeteilt. Die Gruppen A und B wurden in 4 Untergruppen für die einzelnen Obturationen (AL, AZ, AV, AT und EL, EZ, EV, ET) mit jeweils 27 Probenzähnen unterteilt. Nach der Obturation wurden die Zähne koronal mit einer Kompositfüllung mittels SäureÄtztechnik verschlossen. Anschließend erfolgte eine Versiegelung der Zähne mittels Nagelack, mit Ausnahme des apikalen Bereichs, und eine sechstägige Lagerung in 5%iger Methylenblaulösung. Für die Penetrationsversuche (N=18) wurden die Proben zahnachsengerecht geschliffen und unter einem Auflichtmikroskop die apikale Eindringtiefe gemessen. Für die Querschnittsuntersuchungen (N=9) wurden ausgehend vom Apex vier Horizontalschnitte in 1 mm Abstand hergestellt. Diese wurden digital vermessen und die prozentuale Verteilung von Guttapercha/Carrier (G), Sealer (S) und Lufteinschlüssen (L) evaluiert. Die statistische Auswertung der Ergebnisse erfolgte mit SPSS 10.0. Ergebnisse: Bei den Penetrationsversuchen zeigte die statistische Analyse signifikant höhere apikale lineare Eindringtiefen in den mit EndoREZ® behandelten Gruppen. Innerhalb der verschiedenen Obturationstechniken konnte für die Gruppen der vertikalen Kondensation und dem Thermafil®-System kein signifikanter Unterschied festgestellt werden (p<0,05, Tukeys Test). Bei den Querschnittsuntersuchungen mittels angefertigter Horizontalschnitte zeigten die warme vertikale Kondensation und das Thermafil®-System signifikant weniger Lufteinschlüsse als die Füllmethoden mit kalter Guttapercha (p<0,05, Tukeys Test). Schlussfolgerungen: Beide Dichtigkeitsuntersuchungen weisen in die gleiche Richtung. Die Obturation mit dem Thermafil®-System und der vertikalen Kondensation erzielen einen dichten apikalen Verschluss und stellen somit ein Alternative zur klinisch bewährten lateralen Kondensation dar. Der Sealer der neueren Generation (EndoREZ®) zeigt keine Vorteile gegenüber dem Sealer AH Plus. Somit bestätigt der Epoxidharzsealer AH Plus® seine bewährte Stellung innerhalb der endodontischen Behandlung.

description: This paper compares the design andperformanceoftwo types of wide band multi-octave MMIC couplers.Anactive coupler is based on pHEMT devices and fabricated in a GaAs foundry and a passivecouplerusescoplanar waveguide (CPW) multilayer techniques.The multilayer couplers are fabricated on GaAs semi-insulating substrate and are reciprocal and directional. The active coupler design is adapted from the distributed amplifier circuit and is non-reciprocal. On-wafer RF measurements were carried out on the fabricated multilayer directional couplers and pHEMT based couplers. A multilayer quadrature directional coupler with coupling factor of 5dB and isolation of 10dB is realized over 10 to 35 GHz. A 180 coupler using pHEMT devices realized a coupling factor of 5dB and isolation of 26.5dB over2 to 20GHz. For the first time the relative merits of the performance and implementation of these couplers are compared in view of their respective applications.
South Africa's new bilateral investment treaty policy : a reasonable response to a flawed regime?
Creators: name: Steenkamp, Tania
Publisher: name: University of British Columbia
Year: 2014

description: In 2010 South Africa officially adopted a new Bilateral Investment Treaty Policy. The new policy brought to an end a policy review process that was initiated following an investor-State arbitration concerning legislation introduced in the South African mining sector, aimed at promoting equality in South African society, which allegedly breached South Africa’s international obligations in terms of the country’s Bilateral Investment Treaties with Italy and the Belgo-Luxemburg Economic Union respectively. South Africa’s new policy was introduced in the wake of various concerns that have been raised against the investment law regime, specifically with regard to the way in which earlier Bilateral Investment Treaties limited a State’s right to regulate, which could, in turn, negatively impact on a State’s right to development. One of the main limitations on a State’s right to regulate is the overly expansive application of the provision prohibiting expropriation of investments of foreign investors. If applied to any form of taking, including takings resulting from proportional and non-discriminatory regulatory measures that are in the public interest, States face the risk of their actions being challenged in investor-State arbitration. If such an arbitration tribunal finds the disputed regulatory measures to violate a State’s international obligations, States who have not drafted their Bilateral Investment Treaties carefully, will be forced to pay compensation to the investor based solely on the market value of the investment in terms of the standard of paying prompt, adequate and effective compensation. This thesis considers South Africa’s new policy against the background of these concerns. It focuses specifically on the standard for expropriation, the standard of compensation for expropriation and the role of investor-State arbitration in investment law. South Africa’s policy is placed in context through consideration of the Bilateral Investment Treaty policies of Canada and Brazil. Finally, through a study of various treaty models, the thesis considers ways in which these potentially problematic provisions could be drafted to address the concerns raised by South Africa. The thesis concludes that, despite legitimate concerns about the implementation of South Africa’s new policy, the policy itself is reasonable and appropriate in light of the country’s domestic priorities.

description: In nowadays CAD environments for integrated microwave circuit design, dedicated tools for the implementation of user defined component models are becoming more and more important. These tools are mainly oriented to the definition of equivalent circuit models.However, the need for more accurate prediction of nonlinear electron device performance pushes the modelling community towards the research of new, often non-conventional, modelling approaches (e.g., frequency-domain, behavioural, integral models, look-up-table based,state-space based, etc.). In such a context, the model implementation tools usually available may result not sufficiently flexible. The paper provides useful hints andpoints out the main limitations which can be encountered in the implementation of non-conventional electron device models. As an example, the implementation of a Nonlinear Discrete Convolution model will be considered by usingthree different advanced tools: the Model Wizard of AWR Microwave Office, the Model Development Kit and Verilog-A Language of Agilent ADS.

description: We study the long-time behavior of global strong solutions to a hydrodynamic system for nonhomogeneous incompressible nematic liquid crystal flows driven by two types of external forces in a smooth bounded domain in $\mathbb{R}^2$. For arbitrary large regular initial data with the initial density being away from vacuum, we prove the decay of the velocity field for both cases. Furthermore, for the case with asymptotically autonomous external force, we can prove the convergence of the density function and the director vector as time goes to infinity. Estimates on convergence rate are also provided.

description: Ziel dieser Arbeit war die standardisierte Untersuchung der retentiven Eigenschaften, der Einfluss von Sterilisation auf die Retentionskraft und das Korrosionsverhalten dentaler Magnetsysteme. Material und Methode: Es wurden 23 Magnetsysteme zur Verwendung mit natürlichen Zahnwurzeln (11 Systeme) oder auf Implantaten (12 Systeme) untersucht. Bei den Magnetkernen handelt es sich um Neodym-Eisen-Bor- (NdFeB) oder Samarium-Cobalt – (SmCo) Legierungen, die in Titan-, Edelstahl- oder Nichtedelmetallcontainern gekapselt waren. Die Abzugsversuche erfolgten in einer geeichten Prüfmaschine (n=5) über eine Strecke von 40 mm mit einer Geschwindigkeit von 20 mm/min. Für jedes Probenpaar wurde die Messung 10mal wiederholt. Die ermittelten Werte wurden mit den Herstellerangaben verglichen. Anschließend wurde je 1 Implantatabutment sterilisiert (134°C, 10 min.) und unter denselben Bedingungen erneut gemessen. Die Korrosionsversuche erfolgten für jeweils 4 bauartgleiche Proben nach DIN ISO 10271:2001. Die Werte wurden mit dem in DIN ISO 22674:2006 vorgegebenen Grenzwert verglichen. Ergebnisse: Die maximalen Retentionswerte betrugen 1,4 - 6,6N (natürliche Zähne) bzw. 0,7 - 5,8N (Implantatattachments). Die Sterilisation der Implantatabutments führte bei keinem Produkt zu einer Veränderung der Retentionswerte. Die ermittelten Kraftwerte stimmten nicht mit den Herstellerangaben überein. Während der Korrosionsversuche gingen bei allen Proben Ionen in Lösung. Bei einem Produkt konnten in Lösung gegangene Anteile des Magnetkerns (Nd und B) nachgewiesen werden. Alle Werte blieben unter dem Grenzwert. Schlussfolgerung: Die mechanischen Eigenschaften der Magnetsysteme unter klinischen Bedingungen, als auch die Bioverträglichkeit der Korrosionsprodukte auf den menschlichen Organismus sollte in weiteren Studien untersucht werden.

description: We study the impact of sampling theorems on the fidelity of sparse image reconstruction on the sphere. We discuss how a reduction in the number of samples required to represent all information content of a band-limited signal acts to improve the fidelity of sparse image reconstruction, through both the dimensionality and sparsity of signals. To demonstrate this result we consider a simple inpainting problem on the sphere and consider images sparse in the magnitude of their gradient. We develop a framework for total variation (TV) inpainting on the sphere, including fast methods to render the inpainting problem computationally feasible at high-resolution. Recently a new sampling theorem on the sphere was developed, reducing the required number of samples by a factor of two for equiangular sampling schemes. Through numerical simulations we verify the enhanced fidelity of sparse image reconstruction due to the more efficient sampling of the sphere provided by the new sampling theorem.

description: The pseudogap refers to an enigmatic state of matter with unusual physical properties found below a characteristic temperature $T^*$ in hole-doped high-temperature superconductors. Determining $T^*$ is critical for understanding this state. Here we study the simplest model of correlated electron systems, the Hubbard model, with cluster dynamical mean-field theory to find out whether the pseudogap can occur solely because of strong coupling physics and short nonlocal correlations. We find that the pseudogap characteristic temperature $T^*$ is a sharp crossover between different dynamical regimes along a line of thermodynamic anomalies that appears above a first-order phase transition, the Widom line. The Widom line emanating from the critical endpoint of a first-order transition is thus the organizing principle for the pseudogap phase diagram of the cuprates. No additional broken symmetry is necessary to explain the phenomenon. Broken symmetry states appear in the pseudogap and not the other way around.

Diese Arbeit hat den Einfluss der schnell resorbierbaren calciumphosphathaltigen Keramiken 602020, GB14, 305020 und des Referenzmaterials ß-TCP auf zellulärer Ebene hinsichtlich des Einflusses auf Zelladhärenz, Zellproliferation und Zellmorphologie mit Hilfe der konfokalen Lasermikroskopie, der ESEM und des MTT Tests untersucht. Verwendet wurde die Osteosarkomzelllinie MG63 und primäre humane Osteoblasten. Auf allen Materialien kam es zu einer regelmäßigen Zellausbreitung mit suffizienter Proliferation und kräftigen Zelladhäsionen ohne zytotoxischen Reaktionen. Die Abgabe von Calcium und Phosphat aus den Keramiken führt zu einer gesteigerten Zellproliferation. Poröse Oberflächen fördern die Adhäsion und Ausbreitung der Osteoblasten auf allen Materialien. Die Ergebnisse der In-vitro-Untersuchungen bescheinigen allen Materialien eine sehr gute Biokompatibilität mit hohem bioaktivem Potenzial.

description: The mass function of the nonperturbative quark propagator in SU(3) gauge theory shows only a weak dependence on the vortex content of the gauge configurations. Of particular note is the survival of dynamical mass generation on vortex-free configurations having a vanishing string tension. This admits the possibility that mass generation associated with dynamical chiral symmetry breaking persists without confinement. In this presentation, we examine the low-lying ground-state hadron spectrum of the pi, rho, N and Delta and discover that while dynamical mass generation persists in the vortex-free theory, it is not connected to dynamical chiral symmetry breaking. In this way, centre vortices in SU(3) gauge theory are intimately linked to both confinement and dynamical chiral symmetry breaking. We conclude that centre vortices are the essential underlying feature of the QCD vacuum.

description: Die Dissertation befasst sich mit zwei Themenschwerpunkten, der Didaktik und der Baudynamik. Es wurde ein E-Learning-Konzept entwickelt, welches es ermöglicht Studierende in laufende Forschungsprojekte einzubinden und die gewonnenen Erkenntnisse in Form eines Wikis zu sammeln und für nachfolgende Projektteilnehmer zu konkretisieren und nutzbar zu machen. Das E-Learning-Konzept wurde über eine Dauer von drei Jahren erprobt und im Hinblick auf Bedingungen, Verlaufsprozesse und Akzeptanz analysiert und bewertet. Die baudynamischen Untersuchungen, welche u.a. im Rahmen des E-Learning-Projektes durchgeführt wurden, befassten sich mit dem Lastansatz zu fußgängerinduzierten Schwingungen der VDI 2038 – Blatt 1. Der dort abgebildete Last-Zeit-Verlauf weist große Differenzen zu den Bodenreaktionskräften aus der Biomechanik oder anderen Last-Zeit-Verläufen auf. Der Lastansatz wurde durch Versuche konkretisiert und es wurde ein Vorschlag zur Überarbeitung des Lastansatzes in der VDI 2038 erarbeitet.

description: Aktuell fußt die molekulargenetische Charakterisierung einer Lungenkrebserkrankung auf der Untersuchung einer Gewebeprobe, gewonnen durch eine konventionelle Biopsie zum Zeitpunkt der Diagnosestellung. Die Analyse von zirkulierenden Tumorzellen (CTCs) aus dem Blut könnte hier eine supplementäre Plattform bieten. Im Rahmen dieser Arbeit sollte untersucht werden, ob die molekulargenetische Charakterisierung von CTCs mithilfe einer Methodenkombination aus in-vivo-Isolierung der CTCs mittels CellCollector®, immunzytochemischer Detektion, Gesamtgenomamplifikation und anschließender qPCR/HRM- bzw. Mikroarray-Analyse möglich ist. Das KRAS-Gen diente als proof-of-concept-Modell. Nach erfolgreicher Etablierung der Methodik ließ sich in den untersuchten Patientenproben mithilfe des qPCR/HRMA-Assay keine Mutation detektieren. In der Mikroarray-Analyse ließ sich eine Mutation detektieren. Letztendlich muss geschlussfolgert werden, dass die hier erprobte Methodenkombination eher ungeeignet ist.
description: The molecular characterization of lung cancer is based on a tissue sample from a biopsy acquired at the time of diagnosis. Circulating tumor cells (CTCs) could therefore be a supplementary platform. The aim of this study was to demonstrate whether the combination of in-vivo-isolation of CTCs using the CellCollector®, immuncytochemical detection, whole genome amplification followed by qPCR/HRM-Analysis as well as microarray-analysis is suitable for molecular characterization of CTCs in lung cancer patients. The KRAS gene served as a proof-of-concept-model. After successful establishment of the methods no mutation could be detected in the patients samples. Using the microarray-analysis, one KRAS-mutation could be demonstrated in a patients sample. In conclusion the combination of the previously mentioned methods presents itself as rather unsuitable for the molecular characterization of CTCs in lung cancer patients.

Dialogic regulation : the talking cure for corporations
Creators: name: Cody, Michael
Publisher: name: University of British Columbia
Year: 2014

description: The corporations of our future will be whatever we can collectively imagine and work together to make a reality. Dialogic law and regulation is a generative tool that can build the bridge between the present and an imagined future. Regulators keep people on the bridge by identifying the kinds of dialogues we want corporate actors to have and by encouraging, coaching, and sometimes assisting them to have those dialogues. This approach works because small changes in the way corporate actors talk to and interact with each other can have dramatic effects on the emergent corporate culture. This thesis develops and tests a theory of Dialogic Regulation. The theory assumes that corporate law and regulation is about attaining or maintaining a desired corporate behaviour, the best way to change behaviour is to learn a new one, and learning is a social process that involves dialogue. The model was tested using an experimental game where the rules of the game were treated as proxies for the “law” and the authority figure directing the experiment was treated as a proxy for the corporate “regulator”. The game was called the “Pay-Off” game. Half-way through the game the rules were changed using one of three different regulatory techniques: 1) Rules: a simple rule change, 2) Audit: a rule change combined with an audit and punishment procedure for infractions, and 3) Dialogic: a rule change combined with a dialogic intervention about the rules. Participants were tested not only for their behavioural reactions to the interventions (Compliance to the rules) but also to determine if they learned anything about the rules (Adherence to the rules). The games experiment showed that for simply behavioural outcomes the Audit Based Regulation approach was the most effective. The experiment also showed that there is significant promise in a Dialogic Regulation approach if the regulatory desire is to have participants learn. While Dialogic Regulation shows promise, a lot more work needs to be done to refine the application of the theory before it is used in real-life regulatory settings.

description: We prove a version of Poincaré's polyhedron theorem whose requirements are as local as possible. New techniques such as the use of discrete groupoids of isometries are introduced. The theorem may have a wide range of applications and can be generalized to the case of higher dimension and other geometric structures. It is planned as a first step in a program of constructing compact $\mathbb C$-surfaces of general type satisfying $c_1^2=3c_2$.

Iwasawa theory and p-adic L-functions over $\mathbf{Z}_p^2$-extensions

description: In this paper, we define a two-variable analogue of Perrin-Riou's p-adic regulator map for the Iwasawa cohomology of a crystalline representation of the absolute Galois group of $\mathbf{Q}_p$, over a Galois extension of $\mathbf{Q}_p$ whose Galois group is an abelian p-adic Lie group of dimension 2. We use this regulator map to study p-adic representations of global Galois groups over certain abelian extensions of number fields whose localisation at the primes above p are extensions of the above type. In the example of the restriction to an imaginary quadratic field of the representation attached to a modular form, we formulate a conjecture on the existence of a "zeta element", whose image under the regulator map is a p-adic L-function. We show that this conjecture implies the known properties of the 2-variable p-adic L-functions constructed by Perrin-Riou and Kim.

description: Single-cell RNA sequencing studies have suggested that total mRNA content correlates with tumor phenotypes. Technical and analytical challenges, however, have so far impeded at-scale pan-cancer examination of total mRNA content. Here we present a method to quantify tumor-specific total mRNA expression (TmS) from bulk sequencing data, taking into account tumor transcript proportion, purity and ploidy, which are estimated through transcriptomic/genomic deconvolution. We estimate and validate TmS in 6,590 patient tumors across 15 cancer types, identifying significant inter-tumor variability. Across cancers, high TmS is associated with increased risk of disease progression and death. TmS is influenced by cancer-specific patterns of gene alteration and intra-tumor genetic heterogeneity as well as by pan-cancer trends in metabolic dysregulation. Taken together, our results indicate that measuring cell-type-specific total mRNA expression in tumor cells predicts tumor phenotypes and clinical outcomes.
Dynamic Compressive Sensing of Time-Varying Signals via Approximate Message Passing
Creators: name: Ziniel, Justin
name: Schniter, Philip
Publisher: name: arXiv
Year: 2012
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: In this work the dynamic compressive sensing (CS) problem of recovering sparse, correlated, time-varying signals from sub-Nyquist, non-adaptive, linear measurements is explored from a Bayesian perspective. While there has been a handful of previously proposed Bayesian dynamic CS algorithms in the literature, the ability to perform inference on high-dimensional problems in a computationally efficient manner remains elusive. In response, we propose a probabilistic dynamic CS signal model that captures both amplitude and support correlation structure, and describe an approximate message passing algorithm that performs soft signal estimation and support detection with a computational complexity that is linear in all problem dimensions. The algorithm, DCS-AMP, can perform either causal filtering or non-causal smoothing, and is capable of learning model parameters adaptively from the data through an expectation-maximization learning procedure. We provide numerical evidence that DCS-AMP performs within 3 dB of oracle bounds on synthetic data under a variety of operating conditions. We further describe the result of applying DCS-AMP to two real dynamic CS datasets, as well as a frequency estimation task, to bolster our claim that DCS-AMP is capable of offering state-of-the-art performance and speed on real-world high-dimensional problems.

description: Die ehemalige anatomische Privatsammlung der Meckels ist im Jahre 1836 in Universitätsbesitz übergegangen. Seit 1880 befindet sich diese, die liebevoll Meckelsche Sammlung genannt wird, im heutigen Gebäude für Anatomie und Zellbiologie der Martin-Luther-Universität Halle-Wittenberg. In der Nach-Meckel-Zeit kam es zu einer Vermengung von Meckelschen Präparaten und später hinzugefügten Stücken. Daher bestand der Hauptziel dieser Dissertation darin, den heutigen tierisch-teratologischen Sammlungsbestand zu analysieren. Die Untersuchungen schließen die neu durchgeführte Bestandsaufnahme und die gezielte Identifikation der Präparate aus der Ära Johann Friedrich Meckel des Jüngeren (1781-1833) ein. In der Arbeit wird zunächst auf das methodische Vorgehen und die verwendeten Quellen eingegangen. Danach folgt die Auswertung der historischen Kataloge. Heute sind in der Sammlung 57 originale tierisch-teratologische Forschungspräparate aus der Schaffenszeit Meckels d. J. vorhanden. In den Ausführungen zu den Ergebnissen werden einzigartige Forschungsstücke Meckels d. J. vorgestellt. Weiterhin wurde erstmals die Bedeutung der pathologischen Tierpräparate in der Forschungsarbeit Meckels d. J. zur pathologischen Anatomie herausgearbeitet.
description: The Meckels' former private anatomical collection passed over into the possession of the university in 1836. Since 1880 it has been in today's building for Cell Biology of the Martin Luther University Halle-Wittenberg, with the collection being affectionately called the "Meckel Collection". After his death Meckels' the Younger original preparations got blended with pieces added to it in the course of time. Due to this blending the main purpose of this dissertation consists of an analysis with regard to today's inventory of this animal teratologic collection. The study also includes the newly accomplished stocktaking as well as the carefully directed identification of those peparations dating back to the era of Meckel the Younger (1781-1833). At the beginning methodical procedures as well as the sources used are dealt with in this study, which is follwed by an evaluation of the historical catalogues. Nowadays the collection includes 57 original animal teratologic preparations from the working time of Meckel the Younger. Within the discourse concerning the results unique pieces of the latter's research are presented. Furthermore the significance of Meckel's pathological animal preparations within his pathological anatomy was worked out in this study for the first time.

Legittimità e misura in politica

Subjects: SPS/02 Storia delle dottrine politiche

description: Frutto di un'indagine condotta per tappe successive, questo scritto pone sul tappeto le questioni preliminari che Schiera ha incontrato nella ricerca sul DOPO dello Stato moderno, cioè sul suo futuro. Legalità e legittimità ne sono stati storicamente i materiali di costruzione principali, secondo una composizione variabile ma fondamentalmente basata sul principio di autorità che richiede disciplina, cioè obbedienza di molti al comando di pochi. La legge è stata lo strumento razionale - perciò condiviso - di organizzazione del difficile rapporto.
Obbligazione politica derivante da una coscienza razionale ancora precedente: quella dell’insaziabile melancolia dell'essere umano, geneticamente portato alla socialità, ma naturalmente incapace di viverla passivamente. Da qui la costituzionale faziosità comunitaria che va oltre il dato delle differenze di condizione (status) per deviare su sempre nuovi obbiettivi (Border).
L'uomo e il territorio: entrambi sempre più grandi e incontrollabili.
Nuovi spazi e nuovi bisogni, a cui il canto della legge giunge più flebile, perché si è astratto, nel tempo, rendendosi incomprensibile. Necessità di trovare misura. Che la legge torni misura per poter essere regola. E che questa misura torni a essere, per quanto possibile, quella
dell'uomo. Che deve partecipare al concerto, se vuole; ma deve volerlo, se può; ma può, perché, come sempre, la tecnica glielo consente.
Infine, il grande ruolo dell'amministrazione, da rendere una gabbia di seta e non d'acciaio, per co-stringere gli uomini alla partecipazione e alla solidarietà, che potrebbero essere, nel mondo globale, la nuova forma dell'obbligazione alla convivenza.
