International Investment Law in Latin America: problems and prospects

With the bilingual volume International Investment Law in Latin America: Problems and Prospects, Attila Tanzi, Alessandra Asteriti, Rodrigo Polanco Lazo and Paolo Turrini provide a regional perspective on one of the liveliest branches of international law by situating it in one of the most dynamic areas of the world. Latin America has always had an ambivalent relationship with international investment law and, more recently, it has been the home of harsh and resolute criticisms, questioning the ultimate legitimacy of the regime. By bringing together distinguished scholars of this legal field, the volume analyses ongoing trends and draws lessons from the Continent’s past experiences while identifying possible solutions to the important challenges it faces.

Automatic Categorization for Improving Spanish into Spanish Sign Language Machine Translation

This paper describes a preprocessing module for improving the performance of a Spanish into Spanish Sign Language (Lengua de Signos Espanola: LSE) translation system when dealing with sparse training data. This preprocessing module replaces Spanish words with associated tags. The list with Spanish words (vocabulary) and associated tags used by this module is computed automatically considering those signs that show the highest probability of being the translation of every Spanish word. This automatic tag extraction has been compared to a manual strategy achieving almost the same improvement. In this analysis, several alternatives for dealing with non-relevant words have been studied. Non-relevant words are Spanish words not assigned to any sign. The preprocessing module has been incorporated into two well-known statistical translation architectures: a phrase-based system and a Statistical Finite State Transducer (SFST). This system has been developed for a specific application domain: the renewal of Identity Documents and Driver's License. In order to evaluate the system a parallel corpus made up of 4080 Spanish sentences and their LSE translation has been used. The evaluation results revealed a significant performance improvement when including this preprocessing module. In the phrase-based system, the proposed module has given rise to an increase in BLEU (Bilingual Evaluation Understudy) from 73.8% to 81.0% and an increase in the human evaluation score from 0.64 to 0.83. In the case of SFST, BLEU increased from 70.6% to 78.4% and the human evaluation score from 0.65 to 0.82.

Automatic Understanding of ATC Speech: Study of Prospectives and Field Experiments for Several Controller Positions

Although there has been a lot of interest in recognizing and understanding air traffic control (ATC) speech, none of the published works have obtained detailed field data results. We have developed a system able to identify the language spoken and recognize and understand sentences in both Spanish and English. We also present field results for several in-tower controller positions. To the best of our knowledge, this is the first time that field ATC speech (not simulated) is captured, processed, and analyzed. The use of stochastic grammars allows variations in the standard phraseology that appear in field data. The robust understanding algorithm developed has 95% concept accuracy from ATC text input. It also allows changes in the presentation order of the concepts and the correction of errors created by the speech recognition engine improving it by 17% and 25%, respectively, absolute in the percentage of fully correctly understood sentences for English and Spanish in relation to the percentages of fully correctly recognized sentences. The analysis of errors due to the spontaneity of the speech and its comparison to read speech is also carried out. A 96% word accuracy for read speech is reduced to 86% word accuracy for field ATC data for Spanish for the "clearances" task confirming that field data is needed to estimate the performance of a system. A literature review and a critical discussion on the possibilities of speech recognition and understanding technology applied to ATC speech are also given.

The Key Role Transferring Knowledge of Nuclear España, The Spanish Nuclear Society Magazine

The magazine of the Spanish Nuclear Society (SNE), “Nuclear España” is a scientific-technical publication with almost thirty years of uninterrupted edition and more than 300 numbers published. Their pages approach technical subjects related to the nuclear energy, as well as the activities developed by the SNE, especially in national and international meetings. The main part of the magazine is composed by articles written by known specialist of the energy industry. One of the top goals of the magazine is to help on transferring the knowledge from the generation that built the nuclear power plants in Spain and the new generation of professionals that have started its nuclear career in the last years. Each number is monographic, trying to cover as many aspects on an issue as it is possible, with collaborations from the companies, the research centers and universities that helps to have complementary points of view. On the other hand the articles help to deep in the issue´s topic, broadening the view of the readers about the nuclear field and helping to share knowledge across the industry. The news section of the Magazine picks up the actuality of the sector as a whole. The editorial section reflects the opinion of the SNE Governing Board and the Magazine Committee on the subjects of interest in this field. On the other hand, the monthly interview sets out the professional outstanding opinions. With a total of eleven numbers per year, three of them have a noticeable international character: the one dedicated to the operative experiences on the Spanish and European nuclear power plants, the monographic issue devoted tothe Annual Meeting of the SNE and the international issue, which covers the last activities of the Spanish industry in international projects. Both first are bilingual issues (Spanish-English), whereas the international edition is published completely in English. Besides its diffusion through all the members of the SNE, the Magazine is distributed, in the national scope, to companies and organisms related to the nuclear power, universities, research centers, representatives of the Central, Autonomic and Local Administrations, mass media and communication professionals. It is also sent to the utilities and research centers in Europe, United States, South America and Asia.

Factored Translation Models for improving a Speech into Sign Language Translation System

This paper proposes the use of Factored Translation Models (FTMs) for improving a Speech into Sign Language Translation System. These FTMs allow incorporating syntactic-semantic information during the translation process. This new information permits to reduce significantly the translation error rate. This paper also analyses different alternatives for dealing with the non-relevant words. The speech into sign language translation system has been developed and evaluated in a specific application domain: the renewal of Identity Documents and Driver’s License. The translation system uses a phrase-based translation system (Moses). The evaluation results reveal that the BLEU (BiLingual Evaluation Understudy) has improved from 69.1% to 73.9% and the mSER (multiple references Sign Error Rate) has been reduced from 30.6% to 24.8%.

The lexical needs of ESP students in a professional field

This paper examines two kinds of questions relating to the lexical needs of professional ESP students: (1) what range of terms and words do they need help with? (2) what types of dictionary, bilingual and/or monolingual, can they make use of in solving lexical problems?

Bio-climatic Design Handbook: designing public space to reach urban sustainability.

The "Bio-climatic Design Handbook: guidelines for the development of planning regulations" is a tool for urban planning and design professionals planning for the construction of public space taking into account bioclimatic and environmental standards. Based on environmental conditions assessment, urban design guidelines are given. These take into account various scales; from the territory to the microclimatic reality. From these general keys for the design of public space the handbook performs recommendations on specific case studies. The application of bioclimatic techniques in urban design promotes comfort in the public space and the respect for the existing environment, while it influences the energy consumption of buildings that conform this open space. The tool was developed in the context of BIOURB project, where Spain and Portugal cooperate writing this bilingual handbook. The case studies are located in this cross-border region.

Assessment for English language education on the programs at the Agricultural Engineering School of Madrid

The convergence process among European academic degrees pursues the exchange of graduate students and the adaptation of university programs to social demand. Within the framework of the European Higher Education, European universities will need to be more competitive not only by increasing or maintaining the student enrolment, but also in their academic performance. Thus, the reinforcing of English language education within the University Programs might play an important role to reach these objectives. In this sense, a complete survey was accomplished at the Agricultural Egineering School of Madrid (ETSIA ) addressing issues such as: identification the needs for bilingual instruction at ETSIA, identification resources needed and interest and background in English language of students and professors (San José et al., 2013). The conclusions and recommendations to promote the bilingual instruction in the ETSIA, taking into account the approaches followed by other Spanish universities, are presented in this work.

Generating segmental foreign accent

For most of us, speaking in a non-native language involves deviating to some extent from native pronunciation norms. However, the detailed basis for foreign accent (FA) remains elusive, in part due to methodological challenges in isolating segmental from suprasegmental factors. The current study examines the role of segmental features in conveying FA through the use of a generative approach in which accent is localised to single consonantal segments. Three techniques are evaluated: the first requires a highly-proficiency bilingual to produce words with isolated accented segments; the second uses cross-splicing of context-dependent consonants from the non-native language into native words; the third employs hidden Markov model synthesis to blend voice models for both languages. Using English and Spanish as the native/non-native languages respectively, listener cohorts from both languages identified words and rated their degree of FA. All techniques were capable of generating accented words, but to differing degrees. Naturally-produced speech led to the strongest FA ratings and synthetic speech the weakest, which we interpret as the outcome of over-smoothing. Nevertheless, the flexibility offered by synthesising localised accent encourages further development of the method.

Comunicación y seguridad aérea: incidentes y accidentes causados por el uso incorrecto de la lengua inglesa

Este proyecto consiste en el análisis de accidentes e incidentes aéreos causados por problemas en el lenguaje. Se realiza un estudio acerca de la elección del inglés para las comunicaciones en la aviación comercial. Se analiza la reglamentación actual sobre las competencias lingüísticas aplicadas a pilotos y controladores aéreos en la aviación comercial. Además se estudian los problemas lingüísticos causantes de malentendidos en las comunicaciones entre pilotos y controladores aéreos. Finalmente, se analizan en detalle los accidentes e incidentes de mayor importancia causados por problemas lingüísticos, y en los que estos eran un factor relevante en el accidente. Se explican las soluciones aplicadas para minimizar los malentendidos en las comunicaciones, y además se encuesta a un total de trece pilotos españoles con la finalidad de averiguar cuáles son los acentos que más problemas causan, en qué países es donde se tiene más dificultad para entender las comunicaciones aéreas y con mayor frecuencia se emplea una fraseología incorrecta. ABSTRACT. This project consists in the analysis of aviation accidents and incidents caused by language problems. I study why English was chosen as the language of communications in commercial aviation. I analyze the current rules applied for regulating the communication between pilots and controllers. I also study the main linguistic problems that cause misunderstandings in the communications. A detailed study of the most important accidents and incidents caused by misunderstandings is also carried out. I explain the main solutions applied to eradicate or minimize the misunderstandings that could cause an accident, and I also survey a total of thirteen Spanish pilots to directly know what accents are the most difficult ones to understand, which countries tend to modify the standard phraseology, and in which countries Spanish pilots have more problems when communicating with the controllers.

Educación Ambiental y Huella de Carbono en la asignatura de "Technologies" 3º E.S.O.

Este documento presenta el diseño de un proyecto para la asignatura de tecnología de tercero de educación secundaria obligatoria en un instituto de enseñanza bilingüe. Se perfilan una serie de tareas cíclicas que permitirán desarrollar a los alumnos una mayor comprensión sobre el uso de la energía y la importancia del medio ambiente a través de la lengua inglesa. Este ciclo de actividades organizadas en cuatro sesiones se fundamenta en la metodología del Aprendizaje Integrado de Contenidos y Lengua Extranjera, AICLE. A través de esta se persigue el doble objetivo del aprendizaje de la lengua a la par que el del contenido. Para ello, las estrategias que se proponen se centran en el alumno y se apoyan en el trabajo colaborativo, la interacción entre iguales y las metodologías activas y participativas en las que son los propios estudiantes los que diseñan los contenidos y los adaptan a su estilo de aprendizaje. Aunque sin resultados concluyentes, el trabajo supone una aportación más a las propuestas de actividades cooperativas que centran el aprendizaje en las aulas AICLE. This project presents the design of a teaching sequence for the subject of technology in the third grade in a bilingual high school. A task cycle is created with the double objective of providing students with a deeper understanding about the use of energy and the importance of the environment through the English language. The series of activities were organized in four sessions, attending to Content and Language Integrated Learning (CLIL) methodology. Throughout this double focussed objective of learning the language and the subject matter content at the same time, the strategies proposed are focused on the student and support collaborative work, peer interaction and active participatory methodologies, focussed in the students who are the real designers of the content materials based on their own learning style. Although no conclusive results are presented, this work aims to be a contribution to other cooperative task proposals as one of the main basis of CLIL methodology.
