Since the mid 1990s, the momentum behind Corporate Social Responsibility (CSR) has increased. CSR has become an important issue at political, academic and business level. Already since the beginning of the last decade, commentators have suggested that CSR seems to differ between European countries and that said differences appear to be shaped by the country context. Nevertheless, in general, so far, only few empirical cross-country studies have been conducted. In addition, said studies focused mainly on the comparison between Europe as a region and the US. The latter are biased by the selection of only few specific European countries, which are regarded as a proxy for Europe as a whole. Hence, said studies deliver partially contradictory results, since they do not consider that CRS is supposed to be Non-Pan-European. Moreover, cross-country studies of international character, going beyond that regional comparison, have been rather superficial in view of CSR issues to be investigated. And finally, only recently, cross-country research in CSR has started to establish a systematic link between CSR patterns and the country specific institutional context. Also in view of the latter, the focus has been set on the comparison between countries of Anglo American/Saxon tradition and Europe, considering again some specific European countries as a proxy for the region as a whole. <p>Given that lack in the literature, the following explicit calls for empirical cross-country research of CSR in Europe have been formulated: First, to explore differences in view of CSR; and second, to find out if country specific institutional mechanisms are influential in shaping said differences. <p><p>Hence, the dissertation aims at filling this gap and to answer said calls for research by presenting a cross-country research involving two European countries, Germany and Spain. The research aims at exploring differences in view of a variety of CSR issues and at finding out if the national institutional contexts are influential in shaping said differences. <p><p>The dissertation consists of five main parts. In part one, the introductory part, the following is pointed out: motivation, main theoretical frameworks of CSR and main CSR issues in CSR literature. Moreover, a detailed overview on the research design of the three papers, which form part two, three and four, is provided. <p><p>In part two, which is composed of one paper, differences in view of CSR concepts and CSR drivers (analytical framework) between Germany and Spain are explored. The methodology applied was a questionnaire-based postal survey among the 500 largest companies in both, Germany and Spain. <p>The results of the study suggest important differences between the two countries over the analytical framework. In comparison to Spanish companies, the German ones seem to be more attached to the "sustainability" concept of CSR, whereas the Spanish companies favour to a major extent the CSR concept, formulated by the EC and the "Triple Bottom Line" concept. In view of CSR drivers, the results imply that German corporations are to a major extent than their Spanish counterparts driven by secondary stakeholders, whereas corporations in both countries seem to be equally pressured by primary stakeholders to become engaged in CSR. In addition, the findings suggest that CSR in Spain seems to be more "voluntary", whereas, in Germany, it seems to be more "regulated". The analysis of the results with regard to "expectations on positive internal" and "positive external effects" as drivers to CSR suggests a "more competitive advantage centred" approach to CSR among Spanish companies than among German ones, where the corresponding approach is "less competitive advantage centred". And finally, the findungs further suggest, that the country context seems to be influential in shaping most of said differences. <p><p>Part three, which consists of one paper, deals with CSR reporting, which is assumed to deliver insights into the institutionalization of the leading reporting guidelines in CSR, the Global Reporting Initiative (GRI) guidelines, CSR agendas and the communicated rationale behind CSR. The methodology applied was quantitative contents analysis of CSR reports. As sample served companies of the utility industry, listed in the main stock indexes in Germany and Spain. <p>The findings of the study suggest that the institutionalisation of the GRI indicators is low in the corporations investigated in both countries. But, it is especially low in German firms. With regard to CSR agendas, the focus of corporate activities appears to lie among German corporations on those attached to environmental responsibilities, whereas Spanish corporations appear to have in this regard a mixed approach, related to their economic, environmental and social responsibilities. But, in contrast to their German counterparts the economic responsibilities are more emphasized. With regard to the communicated rationale behind CSR, German corporations seem to be driven by normative reasons, the Spanish to a major extent by instrumental ones. And finally, the findings imply that the country context seems to be influential in shaping most of said differences. <p><p>In part four, which contains one paper, differences in the understanding of CG in view of its links to CSR are explored. Currently, scholars discuss the link between CG and CSR and their relational models in the theoretical literature. Hence, to explore the understanding of CG and its links to CSR ,an analytical framework was elaborated, based upon said current theoretical debate. The methodology applied was qualitative contents analysis, conducted in the framework of a web site research. The sample consisted of corporations listed in the main stock indexes in both countries. <p>The findings suggest differences between the two countries with regard to the understanding of CG and its links to CSR and the corresponding relational models. In Spain the understanding of CG seems to be to a major extent linked to the "narrow view" of CG, implied by a major focus on shareholders only in view of corporate responsibilities. In contrast, among German corporations the view appears to be "broad", including other stakeholders than exclusively shareholders in this regard. In addition, the results suggest, that the relational model favoured by German corporations consists of CSR being considered as a part of CG, whereas the Spanish companies seem to relate CG to CSR or at least consider both, CG and CSR, as complementary constituents. And finally, the findings suggest that most of the exposed differences seem to be shaped by mechanisms of the traditional national CG systems. <p><p>In the final main part, part five, the overall conclusions of the dissertation have been formulated. These can be summarized as follows. From an overall perspective the three essays contribute to fill the lack in the literature as already pointed out. They constitute an original answer to the calls for research expressed in this regard. Moreover, they contribute to increase the knowledge on differences in CSR between European countries. And furthermore, through paying attention to country specific institutional mechanisms, they enhance the understanding of said differences induced by the country context or country specificity of CSR. In addition, the three essays have raised important implications for managerial practice, public policies, international and (supra) national institutions and for further research. In view of the implications for managerial practice, the findings suggest to sensitize practitioners with regard to the country specificity of CSR and to undertake corresponding measures in e.g. corporate communication, product and market strategies, employer marketing and organizational and management development terms. With regard to the implications for public policies, international and (supra) national organizations, those with regulatory power should increasingly bear in mind to handle more carefully the outsourcing of said power to private institutions, including NGOs, which play an important role in the "oluntary" regulation of CSR. In addition, those institutions, without regulatory power, which issue e.g. voluntary guidelines, should consider the country specificity of CSR and the "one size does not fit all" problem. Concerning the implications of the findings for further research these are the following: 1) to expand the CSR issues to be investigated in cross-country studies; 2) to intensify cross-country research in Europe in view of the number of countries involved; 3) to consider longitudinal approaches in cross-country research in Europe; 4) to expand said research (1-3) also to SMEs; 5) to increase the scope of institutional mechanisms to be investigated; and 6) to intensify cross-country linguistics research in view of CG and CSR. And finally, the findings of the three essays have delivered substantial contributions to enliven the debate, at academic and practitioner level, in view of the international management of CSR in terms of complexity vs. simplicity. <p> / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

The rapid growth of text based information on the World Wide Web and various applications making use of this data motivates the need for efficient and effective methods to identify and separate the “main content” from the additional content items, such as navigation menus, advertisements, design elements or legal disclaimers. Firstly, in this thesis, we study, develop, and evaluate R2L, DANA, DANAg, and AdDANAg, a family of novel algorithms for extracting the main content of web documents. The main concept behind R2L, which also provided the initial idea and motivation for the other three algorithms, is to use well particularities of Right-to-Left languages for obtaining the main content of web pages. As the English character set and the Right-to-Left character set are encoded in different intervals of the Unicode character set, we can efficiently distinguish the Right-to-Left characters from the English ones in an HTML file. This enables the R2L approach to recognize areas of the HTML file with a high density of Right-to-Left characters and a low density of characters from the English character set. Having recognized these areas, R2L can successfully separate only the Right-to-Left characters. The first extension of the R2L, DANA, improves effectiveness of the baseline algorithm by employing an HTML parser in a post processing phase of R2L for extracting the main content from areas with a high density of Right-to-Left characters. DANAg is the second extension of the R2L and generalizes the idea of R2L to render it language independent. AdDANAg, the third extension of R2L, integrates a new preprocessing step to normalize the hyperlink tags. The presented approaches are analyzed under the aspects of efficiency and effectiveness. We compare them to several established main content extraction algorithms and show that we extend the state-of-the-art in terms of both, efficiency and effectiveness. Secondly, automatically extracting the headline of web articles has many applications. We develop and evaluate a content-based and language-independent approach, TitleFinder, for unsupervised extraction of the headline of web articles. The proposed method achieves high performance in terms of effectiveness and efficiency and outperforms approaches operating on structural and visual features. / Das rasante Wachstum von textbasierten Informationen im World Wide Web und die Vielfalt der Anwendungen, die diese Daten nutzen, macht es notwendig, effiziente und effektive Methoden zu entwickeln, die den Hauptinhalt identifizieren und von den zusätzlichen Inhaltsobjekten wie z.B. Navigations-Menüs, Anzeigen, Design-Elementen oder Haftungsausschlüssen trennen. Zunächst untersuchen, entwickeln und evaluieren wir in dieser Arbeit R2L, DANA, DANAg und AdDANAg, eine Familie von neuartigen Algorithmen zum Extrahieren des Inhalts von Web-Dokumenten. Das grundlegende Konzept hinter R2L, das auch zur Entwicklung der drei weiteren Algorithmen führte, nutzt die Besonderheiten der Rechts-nach-links-Sprachen aus, um den Hauptinhalt von Webseiten zu extrahieren. Da der lateinische Zeichensatz und die Rechts-nach-links-Zeichensätze durch verschiedene Abschnitte des Unicode-Zeichensatzes kodiert werden, lassen sich die Rechts-nach-links-Zeichen leicht von den lateinischen Zeichen in einer HTML-Datei unterscheiden. Das erlaubt dem R2L-Ansatz, Bereiche mit einer hohen Dichte von Rechts-nach-links-Zeichen und wenigen lateinischen Zeichen aus einer HTML-Datei zu erkennen. Aus diesen Bereichen kann dann R2L die Rechts-nach-links-Zeichen extrahieren. Die erste Erweiterung, DANA, verbessert die Wirksamkeit des Baseline-Algorithmus durch die Verwendung eines HTML-Parsers in der Nachbearbeitungsphase des R2L-Algorithmus, um den Inhalt aus Bereichen mit einer hohen Dichte von Rechts-nach-links-Zeichen zu extrahieren. DANAg erweitert den Ansatz des R2L-Algorithmus, so dass eine Sprachunabhängigkeit erreicht wird. Die dritte Erweiterung, AdDANAg, integriert eine neue Vorverarbeitungsschritte, um u.a. die Weblinks zu normalisieren. Die vorgestellten Ansätze werden in Bezug auf Effizienz und Effektivität analysiert. Im Vergleich mit mehreren etablierten Hauptinhalt-Extraktions-Algorithmen zeigen wir, dass sie in diesen Punkten überlegen sind. Darüber hinaus findet die Extraktion der Überschriften aus Web-Artikeln vielfältige Anwendungen. Hierzu entwickeln wir mit TitleFinder einen sich nur auf den Textinhalt beziehenden und sprachabhängigen Ansatz. Das vorgestellte Verfahren ist in Bezug auf Effektivität und Effizienz besser als bekannte Ansätze, die auf strukturellen und visuellen Eigenschaften der HTML-Datei beruhen.

Die Physik der Lauterzeugung (Phonation) wurde mit Hilfe der Theorie der Nichtlinearen Dynamik untersucht. Digitale Hochgeschwindigkeitsaufnamen von Schwingungen in menschlichen und nichtmenschlichen Kehlkoepfen, digitale Bildanalyse, Signalanalyse und Modenanalyse wurden zur quantitativen Beschreibung nichtlinearer Phaenomene eingesetzt. Es wurden nichtlineare Phaenomene bei stimmkranker (pathologischer) menschlicher Lauterzeugung untersucht, wie auch in stimmgesunden Singstimmen und in Kehlkoepfen von nichtmenschlichen Saeugetieren mit Stimmlippen-Membranen. Durch Bifurkationsanalyse eines einfachen mathematischen Modells fuer Stimmlippen mit Membranen konnten beobachtete Lautmuster nichtmenschlicher Saeugetiere qualitativ "nichtlinear gefittet" werden. Die Schwerpunkte dieser Arbeit waren: 1. die Klassifikation von Lautmustern in zeitgenoessischer Vokalmusik, um Erzeugungsmechanismen fuer komplexe Stimmklaenge zu erklaeren, die im kuenstlerischen Kontext vorkommen. Im besonderen war die Rolle der Quelle-Trakt-Kopplung von Interesse; 2. Instabilitaeten in Stimmpatienten, die durch Asymmetrien in einzelnen Stimmlippen wie auch zwischen den Stimmlippen verursacht wurden; 3. dynamische Effekte von duennen, leichten und schwingenden Stimmlippen-Membranen, vertikalen Fortsaetzen der Stimmlippen bei Saeugetieren. Stimmlippen-Membrane finden sich in Kehlkoepfen von Fledermaeusen und Primaten, wo sie einerseits zur Ultraschallerzeugung verwendet werden und andererseits fuer eine grosse Lautvielfalt sorgen. Ein Stimmlippen-Membran-Modell wurde entwickelt, um dieses diverse Lautrepertoire zu reproduzieren. Dieses Modell zeigte zwei Stimmregister. Ueber die Geometry der Stimmlippen-Membrane konnte der subglottale Einsatzdruck minimiert werden und der Druckbereich fuer Phonationen vergroessert werden. Numerische Simulationen demonstrierten, dass das phaenomenologische Stimm-Membran-Modell das Lautrepertoire von Fledermaeusen und Primaten qualitativ reproduzieren konnte. / In this thesis, the physics of phonation was discussed using the theory of nonlinear dynamics. Digital high speed recordings of human and nonhuman laryneal oscillations, image processing, signal analysis, and modal analysis have been used to quantitatively describe nonlinear phenomena in pathological human phonation, healthy voices in singing, and nonhuman mammalian larynges with vocal membranes. Bifurcation analysis of a simple mathematical model for vocal folds with vocal membranes allowed a qualitative ''nonlinear fit'' of observed vocalization patterns in nonhuman mammals. The main focus of the present work was on: 1. the classification of vocalizations of contemporary vocal music to provide insight to production mechanisms of complex sonorities in artistic contexts, especially to nonlinear source-tract coupling; 2. pathological voice instabilities induced by asymmetries within single vocal folds and between vocal folds; 3. the dynamic effects of thin, lightweight, and vibrating vocal membranes as upward extensions of vocal folds in nonhuman mammals. In nonhuman mammals, vocal membranes are one widespread morphological variation of vocal folds. In bats they are responsible to produce ultrasonic echolocation calls. In nonhuman primates they facilitate the production of highly diverse vocalizations. A vocal membrane model was developed to understand the production of these complex calls. Two voice registers were found in the vocal membrane model. The vocal membrane geometry could minimize phonation onset pressure and enlarge the phonatory pressure range of the model. Numerical simulations of the model revealed instabilities that qualitatively resembled observed vocalization patterns in bats and primates.

Diplomová práce přináší příspěvek k problematice inspirace historické prózy devatenáctého století odbornou dějepisnou literaturou. Jejím úkolem je zhodnocení provázanosti Palackého husitské koncepce s vybranými dvěma povídkami Josefa Kajetána Tyla, jejichž děj je situován do první poloviny patnáctého století v Čechách. První část diplomové práce uvádí stručnou charakteristiku obou autorů a jejich tvorby s historickou tematikou. Následující teoretická kapitola je věnována pohledu na husitství v devatenáctém století. Druhá část práce je zaměřena prakticky, neboť vedle srovnání výkladu dějin oběma autory také obsahuje subjektivní interpretaci literárních kvalit postav a okolností, jež si Tyl domýšlí.
