The trading mechanism, cross listed stocks:A comparison of the Paris Bourse and SEAQ-International

This paper studies the behaviour of returns for a sample of cross-listed stocks, listed on both the Paris Bourse and SEAQ-International in London. The aim of the paper is to discover which market adjusts to fundamental news more quickly, the home market of Paris or SEAQ-International. We find that prices in London adjust to changes in their fundamental value more slowly than Paris prices, despite the ability to quickly arbitrage between the two markets. We suggest that this finding may reflect the type of trading, which takes place in the two markets and differences associated with the reporting of large trades. We also estimate the amount of noise present in the two markets and show that the Paris market is more noisy than London. © 2003 Published by Elsevier B.V.

The French Confederation Generale du Travail and the International Secretariat of National Trade Union Centres (1900-1914):French syndicalist attitudes towards internationalism and the International Labour Movement

This thesis examines relations between the French Confederation Generale du Travail (CGT) and the labour movements of other countries in the years leading up to the First World War. The aim of the study is to examine the CGT's policy of internationalism in practice, both in relations with other labour movements and in its membership of the International Secretariat of National Trade Union Centres (between 1900 and 1914). In particular, the relationship between the French and German labour movements is explored in the light of the events of August 1914. This study shows that the relationship was a reflection of the respective positions of the French and German labour movements in the international movement. It also subjects to close scrutiny the assumption, widely made before 1914, that workers had more in common with each other than with the ruling classes of their own country, by analysing the extent of, and the reasons for internationalism and international cooperation in the labour movement. As a study of the International Secretariat of National Trade Union Centres, an organisation about which very little has previously been written, this thesis complements existing work on the international labour movement prior to 1914. It also provides new insights into the French CGT by concentrating on the fundamental areas of internationalism and opposition to war, and offers fresh contributions to the continuing debate on the international labour movement and its response to the outbreak of war.

The global audit profession and the international financial architecture:understanding regulatory relationships at a time of financial crisis

This paper explores how regulatory relationships in the global audit arena are being affected by the current financial crisis. Key policy initiatives and debates are analyzed, along with institutional interactions, in particular between the International Federation of Accountants (IFAC), international regulators and the large audit firms. The events are placed in the context of the new international financial architecture which has developed over the last decade. Using the illustrative lens of bank auditing, questions are asked of the nature and status of audit practice and the regulatory arrangements governing such practice. The paper shows the active nature of the regulatory responses to the crisis and the shifting and competing influences among key regulatory and professional participants in the global audit arena. Emphasis is placed on the need for audit researchers to be sensitive to the developing global financial architecture, and its potential implications for the study of audit practice in different national and international contexts.

Some historical extracts relevant to the discovery and application of the diffraction of X-rays by crystals to contribute to the centennial celebration and the International Year of Crystallography

Illustrative extracts from the writings of Paul P. Ewald and of Max von Laue are presented. The latter in turn contains extensive text contributions from William Lawrence Bragg. These selections we have chosen so as to indicate the nature of the discovery of X-ray diffraction from crystals (experiments undertaken by Friedrich, Knipping and von Laue) and its early and prompt application in crystal structure analyses (by William Henry Bragg and William Lawrence Bragg). The platform for these discoveries was provided by a macroscopic physics problem dealt with by Ewald in his doctoral thesis with Arnold Sommerfeld in the Munich Physics Department, which is also where von Laue was based. W.L. Bragg was a student in Cambridge who used Trinity College Cambridge as his address on his early papers; experimental work was done by him in the Cavendish Laboratory, Cambridge, and also with his father, W.H. Bragg, in the Leeds University Physics Department. Of further historical interest is the award of an Honorary DSc (Doctor of Science) degree in 1936 to Max von Laue by the University of Manchester, UK, while William Lawrence Bragg was Langworthy Professor of Physics there. © 2012 Copyright Taylor and Francis Group, LLC.

Researching language teacher cognition and practice:international case studies

This book presents a novel approach to discussing how to research language teacher cognition and practice. An introductory chapter by theeditors and an overview of the research field by Simon Borg precede eigh case studies written by new researchers, each of which focuses on one approach to collecting data. These approaches range from questionnaires and focus groups to think aloud, stimulated recall, and oral reflective journals. Each case study is commented on by a leading expert in the field - JD Brown, Martin Bygate, Donald Freeman, Alan Maley, Jerry Gebhard, Thoma Farrell, Susan Gass, and Jill Burton. Readers are encouraged to enter th conversation by reflecting on a set of questions and tasks in each chapter.

Vínculo empregatício: interpretação judicial do direito fundamental à relação de emprego protegida e seus efeitos

The Federal Constitution, in Article 1, sections III and IV, lifted the work as the foundation of the Federative Republic of Brazil, including work as a social guarantee in Article 6, listing in its Article 7 minimal guarantees role with respect to social rights of workers. Although elevated to constitutional rights, these social rights of workers have in the judicial interpretation of the characteristic elements of the employment relationship, sometimes a mismatch with the legal and constitutional order, when, in deciding not ponder such elements, causing damage economic and social benefits to all workers, thus affecting the very constitutional basis of worker protection, there is therefore situations in which there must be part of unavailability of rights by the employee. Therefore, identifying the characteristic elements of employment, means allow immediate legal finding about possible illegality perpetrated by the employer, precisely because the sentence recognizes be merely declaratory noting, therefore, the elements that make up the juridical system normative in order to establish the characterization of employment in step with the effective observance and guarantee of social rights and therefore the employer's performance limiter as pertains to hiring and employee dismissal. This point is it's main element of this work, which is fundamental for the exegesis of the theme to limit the autonomy of the will. There is no denying, therefore, the need to extend the effects of these guarantees in the employment contract. In this context, therefore, jumping the guarantees of employees, embodied in particular in the Consolidation of Labor Laws, and especially in the Federal Constitution and international protection instruments to ensure the fundamental right to secure employment relationship, where technological advancement, social and economic, reflect directly, such as the parassubordinação, and claiming more and more systematic resolutions, especially when evidence gaps' values, which elevate the debate about the need for increased use of precedents of order to support the judgments, often beset with aspects of unconstitutionality, all in compliance with the integration of standards, seeking legal enforcement of this bond and providing legal certainty, there emerged, so the essence of the theme: discuss to what extent the distortion of employment limits the effectiveness of social rights and what its legal effects, since the constitutional standard for social guarantees protects equally worker admission.

Nanotechnology in food industry II: risk assessment and legislation

Currently, there is increasing use of nanomaterials in the food industry thanks to the many advantages offered and make the products that contain them more competitive in the market. Their physicochemical properties often differ from those of bulk materials, which require specialized risk assessment. This should cover the risks to the health of workers and consumers as well as possible environmental risks. The risk assessment methods must go updating due to more widespread use of nanomaterials, especially now that are making their way down to consumer products. Today there is no specific legislation for nanomaterials, but there are several european dispositions and regulations that include them. This review gives an overview of the risk assessment and the existing current legislation regarding the use of nanotechnology in the food industry.

What do school principals do? Leadership practices in Spain drawn from PISA and TALIS international studies

Principals play a key role in schools. Their actions affect the efficacy of schools and indirectly on the students’ academic performance. Numerous studies describe the different activities that principals perform in their daily practice, grouping them in dimensions, not existing unanimity neither around the practices carried out nor the dimensions. In Spain, the new educational law, LOMCE, emphasizes the importance of looking into what international research says regarding the field of education to support the need for change and justify the ones that are being made, and develops an extended list of competences of the principal. This study is a synthesis of a narrative research with the following analysis unit: the results of the PISA (Programme for International Student Assessment) and TALIS (Teaching and Learning International Study) international reports, and the data provided on school leadership and their practices, from which conclusions are inferred, comparing them with the competences stated in the LOMCE. The comparative analysis of the leadership practices presented depicts a still uneven and heterogeneous scenario, not existing agreement neither for the setting of boundaries for the leadership dimensions, nor for the number of practices that constitute them. Such a scenario points towards the need for further empirical research, in order to accurately obtain a homogeneous catalogue of the actions carried out by principal, that may open the door to the development of the role of principal, and to the improvement of effectiveness and performance of schools, as it is suggested internationally, and it is an objective of the new educational law.
