The New Institutions of Transatlantic Aviation

This article focuses on the institutions of transatlantic aviation since 1945, and aims at extracting from this historical process topical policy implications. Using the methodology of an analytic narrative, we describe and explain the creation of the international cartel institutions in the 1940s, their operation throughout the 1950s and 60s, their increasing vulnerability in the 1970s, and then the progressive liberalization of the whole system. Our analytic narrative has a natural end, marked by the signing of an Open Skies Agreement between the US and the EU in 2007. We place particular explanatory power on (a) the progressive liberalization of the US domestic market, and (b) the active role of the European Commission in Europe. More specifically, we explain these developments using two frameworks. First, a “political limit pricing” model, which seemed promising, then failed, and then seemed promising again because it failed. Second, a strategic bargaining model inspired by Susanne Schmidt’s analysis of how the European Commission uses the threat of infringement proceedings to force member governments into line and obtain the sole negotiating power in transatlantic aviation.

Elections in 2009? Progress and obstacles in the construction of peace in the Ivory Coast

In 2002 in the Ivory Coast three months of armed conflict ended with the division of the country. Two regions were separated by an interposition line controlled by the French Forces Licorne. This significant peace process was maintained over time, but characterized for lack of mutual confidence and political immobility, which led to an impasse and the continuation of Laurent Gbagbo in the presidency. Moreover, the peace building process was less successful because the different political agreements failed to address some of the main national problems, such as land property and identity issues. The following paper aims first to analyze the main facts and causes that instigated the conflict since the coup d’état in 2002. Secondly, the paper will analyze the peace process and point out the key elements of the Ouagadougou Peace Agreement (2007): the creation of a new and unique armed forces structure, as well as the identification of the population and implementation of an electoral process. The main goal is to provide the International Catalan Institute for Peace (ICIP) a working tool in order to send an electoral observation mission to this African country by November 2009.

The learning process as a cooperative task among teachers and students

This research project gathers several ideas and guidelines on professional improvement as a teacher. This study includes two empirical studies. The first one focuses mainly on the teacher's figure. It is meant to be a study of the several resources that the teacher uses in order to construct the student's knowledge in an English classroom context. The second empirical study focuses on the students. It is a study on how students learn cooperatively by analyzing their oral productions when working in small groups

Contact melting of a three-dimensional phase change material on a flat substrate

In this paper a model is developed to describe the three dimensional contact melting process of a cuboid on a heated surface. The mathematical description involves two heat equations (one in the solid and one in the melt), the Navier-Stokes equations for the flow in the melt, a Stefan condition at the phase change interface and a force balance between the weight of the solid and the countering pressure in the melt. In the solid an optimised heat balance integral method is used to approximate the temperature. In the liquid the small aspect ratio allows the Navier-Stokes and heat equations to be simplified considerably so that the liquid pressure may be determined using an igenfunction expansion and finally the problem is reduced to solving three first order ordinary differential equations. Results are presented showing the evolution of the melting process. Further reductions to the system are made to provide simple guidelines concerning the process. Comparison of the solutions with experimental data on the melting of n-octadecane shows excellent agreement.

An axiomatic justification of mediation in bankruptcy problems.

This paper provides a natural way of reaching an agreement between two prominent proposals in a bankruptcy problem. Particularly, using the fact that such problems can be faced from two different points of views, awards and losses, we justify the average of any pair of dual bankruptcy rules through the definition a double recursive process. Finally, by considering three posible sets of equity principles that a particular society may agree on, we retrieve the average of old and well known bankruptcy rules, the Constrained Equal Awards and the Constrained Equal Losses rules, Piniles’ rule and its dual rule, and the Constrained Egalitarian rule and its dual rule. Keywords: Bankruptcy problems, Midpoint, Bounds, Duality, Recursivity. JEL classification: C71, D63, D71.

How The 1996 Hotel Majestic agreement may explain a future PP/CiU relationship in Madrid

Some historians have argued that 1996 marked a ‘second transition’ for Spain because of the return to power of the political right in Madrid and that the relationship and eventual pact between the Partido Popular (PP) and Convergència i Unió (CiU) meant that the state could finally escape the ghosts of its Francoist past. For this research, face-to-face interviews were conducted with Catalan Members of Parliament who served under either José María Aznar or Jordi Pujol in Madrid or Barcelona. Drawing upon both interviews and other evidence, including the analysis of election results and the 1996 Hotel Majestic Agreement, the research seeks to provide a better understanding of the previous relationships between the PP and CiU and their leaders in order to understand what lessons might be learnt that would contribute to anticipating and explaining possible future negotiations between the two parties. This is attempted by first examining the potential costs and benefits of political pacts between centre (Madrid) and periphery (Barcelona). Secondly, due to many interviewees making reference to Salvador Espriu’s work La Pell de Brau, the three routes of Espriu’s Catalan nationalism are put into the context of the political pacts. Finally, the likelihood of future agreements between PP and CiU are hypothesized, not only how those agreements may (or may not) come about, but also, what might the result of those negotiations be. Ultimately, it is concluded that the benefits of the Hotel Majestic Agreement outweighed the costs, thus leaving the door open for future negotiations, even if some of those interviewed disagreed.

Productivity in southern European small firms: When and how work organization complements process innovation

The aim of this paper is to analyse the effects of human capital, advanced manufacturing technologies (AMT), and new work organizational practices on firm productivity, while taking into account the synergies existing between them. This study expands current knowledge in this area in two ways. First, in contrast with previous works, we focus on AMT and not ICT (information and communication technologies). Second, we use a unique employer-employee data set for small firms in a particular area of southern Europe (Catalonia, Spain). Using a small firm data set, allows us to analyse the particular case of small and medium enterprises, since we cannot assume they have the same characteristics as large firms. The results provide evidence in favor of the complementarity hypothesis between human capital, advanced manufacturing technologies, and new work organization practices, although we show that the complementarity effects depend on what type of work organization practices are used by a firm. For small and medium Catalan firms, the only set of work organization practices that improve the benefits of human capital and technology investment are those practices which are more quality oriented, such as quality circles, problem-solving groups or total quality management.

PERSONAL(ONTO) : Personalizing the Learning Process in Virtual Environments by means of Adaptive Formative Itineraries based on Reusable Learning Objects and Ontologies TIN2006-15107-C02

Personalization in e-learning allows the adaptation of contents, learning strategiesand educational resources to the competencies, previous knowledge or preferences of the student. This project takes a multidisciplinary perspective for devising standards-based personalization capabilities into virtual e-learning environments, focusing on the conceptof adaptive learning itinerary, using reusable learning objects as the basis of the system and using ontologies and semantic web technologies.

The agreement between ipsative and normative questionnaires using compositional data analysis techniques

The main instrument used in psychological measurement is the self-report questionnaire. One of its majordrawbacks however is its susceptibility to response biases. A known strategy to control these biases hasbeen the use of so-called ipsative items. Ipsative items are items that require the respondent to makebetween-scale comparisons within each item. The selected option determines to which scale the weight ofthe answer is attributed. Consequently in questionnaires only consisting of ipsative items everyrespondent is allotted an equal amount, i.e. the total score, that each can distribute differently over thescales. Therefore this type of response format yields data that can be considered compositional from itsinception.Methodological oriented psychologists have heavily criticized this type of item format, since the resultingdata is also marked by the associated unfavourable statistical properties. Nevertheless, clinicians havekept using these questionnaires to their satisfaction. This investigation therefore aims to evaluate bothpositions and addresses the similarities and differences between the two data collection methods. Theultimate objective is to formulate a guideline when to use which type of item format.The comparison is based on data obtained with both an ipsative and normative version of threepsychological questionnaires, which were administered to 502 first-year students in psychology accordingto a balanced within-subjects design. Previous research only compared the direct ipsative scale scoreswith the derived ipsative scale scores. The use of compositional data analysis techniques also enables oneto compare derived normative score ratios with direct normative score ratios. The addition of the secondcomparison not only offers the advantage of a better-balanced research strategy. In principle it also allowsfor parametric testing in the evaluation

Abstracting qualitative information for process supervision

Supervisory systems evolution makes the obtaining of significant information from processes more important in the way that the supervision systems' particular tasks are simplified. So, having signal treatment tools capable of obtaining elaborate information from the process data is important. In this paper, a tool that obtains qualitative data about the trends and oscillation of signals is presented. An application of this tool is presented as well. In this case, the tool, implemented in a computer-aided control systems design (CACSD) environment, is used in order to give to an expert system for fault detection in a laboratory plant

The European Union Perception of Cuba: From Frustation to Irritation

On Friday May 16, the Ministry of Foreign Affairs of Cuba summoned the newly-appointed charged’affairs of the European Commission in Havana and announced the withdrawal of the application procedure for membership in the Cotonou Agreement of the Africa, Caribbean, and Pacific (ACP) countries, and in fact renouncing to benefit from European development aid.1 In a blistering note published in the Granma official newspaper of the Cuban Communist Party, the government blamed the EU Commission for exerting undue pressure, its alleged alignment with the policies of the United States, and censure for the measures taken by Cuba during the previous weeks.2 In reality, Cuba avoided an embarrasin flat rejection for its application. This was the anti-climatic ending for a long process that can be traced back to the end of the Cold War, in a context where Cuba has been testing alternative grounds to substitute for the overwhelming protection of the Soviet Union

Modelling the cardiovascular system for automatic interpretation of the blood pressure curve

A four compartment model of the cardiovascular system is developed. To allow for easy interpretation and to minimise the number of parameters, an effort was made to keep the model as simple as possible. A sensitivity analysis is first carried out to determine which are the most important model parameters to characterise the blood pressure signal. A four stage process is then described which accurately determines all parameter values. This process is applied to data from three patients and good agreement is shown in all cases.
