La sécurité collective dans l’unipolarité : la crise nucléaire iranienne

L’argument central de notre thèse est qu’une structure internationale unipolaire non hégémonique favorise la sécurité collective. Après avoir montré que telle est la structure actuelle et avoir justifié notre positionnement théorique néolibéral, nous avons eu recours au modèle d’interaction du « leader-suiveur de Stackelberg », pour démontrer qu’une coopération conflictuelle entre États rationnels est possible, ce qui leur permet de surmonter leur dilemme de l’action collective. Une coopération possible en raison de l’existence d’un intérêt mutuel et d’un leader favorisant la coopération entre ces États, ainsi que de conditions leur permettant de mettre en place une ‘stratégie de la réciprocité’. Ils forment alors ce qu’on appelle le « groupe de Stackelberg ». Le suiveur de la périphérie, ou ‘défecteur’ doit, pour sa part, non seulement s’ajuster à l’intérêt mutuel ainsi défini, mais aussi coopérer et négocier avec le groupe, et ce, sous la pression de sanctions, voire d’un usage ultime de la force si besoin est. Après l’éventuel succès de ces négociations, un équilibre de Stackelberg favorisé par le leader, soit la puissance unipolaire et non hégémonique, est alors atteint et la coopération permet, alors, à chacun de retirer un bénéfice de cet intérêt mutuel. Dans notre cas, le groupe de Stackelberg est constitué des membres du G5 + 1, soit les cinq membres permanents du Conseil de Sécurité de l’ONU et de l’Allemagne, agissant sous le leadership américain; l’Iran est un suiveur de la périphérie, soupçonné de défection, et l’intérêt mutuel est celui de la lutte contre la prolifération des ADM. Notre évaluation empirique montre que les conditions de la réciprocité des membres de ce groupe sont réunies et que celles de l’Iran sont en cours de négociation.

Internacionalizacion de las empresas colombianas casos de estudio: Hamburguesas el corral y Pan pa' ya

Con el presente trabajo se pretende describir el plan estratégico internacional que siguió PAN PA’ YA! y HAMBURGUESAS EL CORRAL en el proceso de exportación de sus productos y formalización de la comercialización a nivel internacional, mediante la formación de alianzas entre empresas y distribuidores del mercado. Por medio de un estudio de las diferentes teorías de internacionalización se pudo identificar el proceso a través del cual las empresas colombianas iniciaron sus operaciones en el extranjero. PAN PA’ YA! empezó con el sueño de ser una de las panaderías más grandes en Colombia, hoy en día constituye un negocio integral. Con el paso de los años y el movimiento diario del mercado colombiano la empresa se ha consolidado fuertemente.

The relationship between board of director's nationality diversity and financial performance

Companies are moving to a more international structure; going into new markets and having an increased competition in all fronts. Therefore, the practices that lead companies to a more efficient and competitive position are praised. The management of the workforce comes as one of the main concerns of companies, aiming at performance enhancing and at creating better environments that both attract and maintain the professional talents. In an increasingly international environment, companies tend to look for the specialists and best professionals, regardless of their nationality. This new structure with several different nationalities working together poses new challenges for companies. Understanding if and how a more diverse has a relationship with financial performance is the starting point for better managing this new corporate structure.

Las potencias subregionales en el sistema internacional de posguerra fría: ¿nuevos actores en la política internacional?

En trabajos anteriores, hemos avanzado en la identificación y diferenciación de tres categorías de potencias: potencias mundiales, potencias medias y potencias regionales. Pero, más allá de las potencias mundiales y las potencias medias que se encuentran en el centro del sistema-mundial, y las potencias regionales que se ubican en la semiperiferia, ¿es posible hablar de potencias que se encuentren en la periferia? Como se trata de Estados periféricos, ¿pueden ser calificados como “potencias”? ¿En qué radicaría su relevancia y envergadura? Dichas “potencias” ¿pueden ser agrupadas en una nueva categoría? De ser así ¿qué características compartirían? El objetivo de este documento es proponer una nueva  categoría de potencias en el sistema internacional: las potencias subregionales.

Market structure of international construction professional services: Evidences from top design firms

Construction professional service (CPS) in the international arena has been very competitive despite that the industry is proliferating at a high rate. To excel in international business, CPS firms have the importance of building overseas competition strategies on a proper understanding of the international CPS (I-CPS) market. However, subject to borderless trade, information technology–based networking, global outsourcing, and changing forms of procurement, the I-CPS market structure has become more covert, intricate, and unstraightforward than before. Through examining business competition among top international design firms, this study aims to identify the attributes of the I-CPS market structure from two perspectives—concentration and turnover. Data from Engineering News-Record over the period 2001–2011 were collected to calculate market concentration ratios and turnover indices. The results show that I-CPS competition is characterized by atomism, much turbulence with a steady increase in competition intensity, and the predominant role of new entrants and exiting firms in market turnovers. The combination of concentration and turnover is found useful to address the attributes of the I-CPS market structure, which favors I-CPS firms to formulate international competition strategies in due ways.

International perspectives on the influence of structure and process of weaning from mechanical ventilation.

Background 
Recently, clinical and research attention has been focused on refining weaning processes to improve outcomes for critically ill patients who require mechanical ventilation. One such process, use of a weaning protocol, has yielded conflicting results, arguably because of the influence of existing context and processes.

Objective 
To compare international data to assess differences in context and processes in intensive care units that could influence weaning.  

Methods 
Review of existing national data on provision of care for critically ill patients, including structure, staffing, skill mix, education, roles, and responsibilities for weaning in intensive care units of selected countries.

Results 
Australia, New Zealand, Denmark, Norway, Sweden, and the United Kingdom showed similarities in critical care provision, structure, skill mix, and staffing ratios in intensive care units. Weaning in these countries is generally a collaborative process between nurses and physicians. Notable differences in intensive care units in the United States were the frequent use of an open structure and inclusion of respiratory therapists on the intensive care unit’s health care team. Nurses may be excluded from direct management of ventilator weaning in some institutions, as this role is primarily assumed by respiratory therapists guided by medical directives. Availability of critical care beds was highest in the United States and lowest in the United Kingdom.

Conclusion 
Context and processes of care that could influence ventilator weaning outcomes varied considerably across countries. Further quantification of these contextual influences should be considered when translating research findings into local clinical practice and when designing randomized, controlled trials.

GPCR structure, function, drug discovery and crystallography: report from Academia-Industry International Conference (UK Royal Society) Chicheley Hall, 1-2 September 2014

G-protein coupled receptors (GPCRs) are the targets of over half of all prescribed drugs today. The UniProt database has records for about 800 proteins classified as GPCRs, but drugs have only been developed against 50 of these. Thus, there is huge potential in terms of the number of targets for new therapies to be designed. Several breakthroughs in GPCRs biased pharmacology, structural biology, modelling and scoring have resulted in a resurgence of interest in GPCRs as drug targets. Therefore, an international conference, sponsored by the Royal Society, with world-renowned researchers from industry and academia was recently held to discuss recent progress and highlight key areas of future research needed to accelerate GPCR drug discovery. Several key points emerged. Firstly, structures for all three major classes of GPCRs have now been solved and there is increasing coverage across the GPCR phylogenetic tree. This is likely to be substantially enhanced with data from x-ray free electron sources as they move beyond proof of concept. Secondly, the concept of biased signalling or functional selectivity is likely to be prevalent in many GPCRs, and this presents exciting new opportunities for selectivity and the control of side effects, especially when combined with increasing data regarding allosteric modulation. Thirdly, there will almost certainly be some GPCRs that will remain difficult targets because they exhibit complex ligand dependencies and have many metastable states rendering them difficult to resolve by crystallographic methods. Subtle effects within the packing of the transmembrane helices are likely to mask and contribute to this aspect, which may play a role in species dependent behaviour. This is particularly important because it has ramifications for how we interpret pre-clinical data. In summary, collaborative efforts between industry and academia have delivered significant progress in terms of structure and understanding of GPCRs and will be essential for resolving problems associated with the more difficult targets in the future.

Essays on international prices and the subjacent market structure

Esta tese utiliza a informação contida em preços internacionais para identificar parâmetros de modelos de comércio sob competição imperfeita, desta forma permitindo inferência sobre o comportamento das exportações, sobre os ganhos de troca da abertura comercial e sobre a variedade de bens produzidos domesticamente. Em primeiro lugar, investigamos o repasse cambial, no longo prazo, para os preços praticados por exportadores brasileiros. O foco no longo prazo permite controlar os efeitos da rigidez de preço no curto prazo, de maneira que o repasse incompleto evidencie competição imperfeita com preços flexíveis. Em segundo lugar, calculamos os ganhos de troca de novas variedades de bens importados baseando-nos em estimativas para as elasticidades de substituição desagregadas. Finalmente, qualificamos a ênfase da literatura de comércio em ganhos de eficiência no lugar de ganhos de variedade, demonstrando que a variedade de bens produzidos domesticamente se amplia após aberturas comerciais desde que as firmas tenham uma margem de decisão em bens intermediários ou na qualificação da mão de obra.

Aviation English: Structure and Importance of an International Airborne Language

In today’s globalized world, air travel is one of the fastest growing markets. Millions of aircrafts take off and then touch down all around the world each day. This well-synchronized symphony, however, is much more complex than it seems, and communication – language - plays a crucial role during a plane’s journey. Misunderstandings and miscommunications can have disastrous effects, so the adoption of a standard phraseology to be used during flight is a means to overcome language barriers, avoid ambiguous expressions and guarantee a safe and effective operation of an aircraft. Little is known about the interaction that goes on between pilots and air traffic controllers (ATCOs), and even though the language of aviation is English, cockpit communication can be hard to understand for people who are not familiar with this specific language. The scope of this thesis is to examine the origins of this uncommon language, the characteristics and peculiarities of air communication and to shed a little light on this mystery called Aviation English.
