La protection des investissements suisses à l'étranger dans le cadre des accords de promotion et de protection des investissements

Dotée d'une économie traditionnellement ouverte vers l'extérieur, la Suisse dispose de l'un des plus vastes réseaux au monde d'accords bilatéraux de promotion et de protection des investissements (APPI). Instrument dont la faible notoriété est inversement proportionnelle au nombre élevé d'accords concernés et aux montants en jeu, les APPI visent à conférer aux entreprises suisses établies à l'étranger - et vice-versa - une large protection contre les risques non commerciaux. Le présent ouvrage s'attache à l'analyse du développement et du contenu des APPI conclus par la Suisse avec ses partenaires, essentiellement des pays en développement. S'appuyant sur la doctrine et la jurisprudence internationales, il traite de manière détaillée des droits matériels et procéduraux parfois contestés que ce type d'accords offrent aux investisseurs et met en évidence les particularités des APPI du réseau suisse.

Small scale underwater change detection

In this paper, we present a method to deal with the constraints of the underwater medium for finding changes between sequences of underwater images. One of the main problems of underwater medium for automatically detecting changes is the low altitude of the camera when taking pictures. This emphasise the parallax effect between the images as they are not taken exactly at the same position. In order to solve this problem, we are geometrically registering the images together taking into account the relief of the scene

Change in defense mechanisms and coping patterns during the course of 2-year-long psychotherapy and psychoanalysis for recurrent depression: a pilot study of a randomized controlled trial.

Very little research has been conducted so far to study the potential mechanisms of change in long-term active psychological treatments of recurrent depression. The present pilot randomized controlled trial aimed to determine the feasibility of studying the change process occurring in patients during the course of 2-year-long dynamic psychotherapy, psychoanalysis, and cognitive therapy, as compared with clinical management. In total, eight outpatients presenting with recurrent depression, two patients per treatment arm, were included. All patients were randomly assigned to one of the four treatment conditions. Defense mechanisms and coping patterns were assessed using validated observer-rated methodology based on transcribed, semistructured follow-along independent dynamic interviews. The results indicated that, whereas some patients in the active treatments changed on the symptomatic levels, some others remained unchanged during the course of their 2-year-long treatment. However, with regard to potential mechanisms of change in these patients, changes in defense mechanisms and coping patterns were revealed to be important processes over time in successful therapies and, to a lesser extent, in less successful treatments. No change was found either on outcome or on the process measure for the control condition, that is, clinical management. These results are discussed along with previous data comparing change in defense mechanisms and coping during the course of treatments.

Corne cutanée du bord libre palpébral. A propos d'une observation anatomo-clinique [A cutaneous horn of the free margin of the eyelid: an anatomical and clinical observation].

A cutaneous horn was observed close to the free margin of the inferior right eyelid in a 26-year-old-male patient. A minimal resection was primarily performed. Histopathologic study disclosed a precancerous keratosis. As the tumor had not been entirely excised, a complementary resection was performed secondarily to obtain the entire resection of the tumor.

Geoecological drivers of cerrado heterogeneity and 13C natural abundance in oxisols after land-use change

The 13C natural abundance technique was applied to study C dynamics after land-use change from native savanna to Brachiaria, Pinus, and Eucalyptus in differently textured Cerrado Oxisols. But due to differences in the d13C signatures of subsoils under native savanna and under introduced species, C substitution could only be calculated based on results of cultivated soils nearby. It was estimated that after 20 years, Pinus C had replaced only 5 % of the native C in the 0-1.2 m layer, in which substitution was restricted to the top 0.4 m. Conversely, after 12 years, Brachiaria had replaced 21 % of Cerrado C to a depth of 1.2 m, where substitution decreased only slightly throughout the entire profile. The high d13C values in the subsoils of the cultivated sites led to the hypothesis that the natural vegetation there had been grassland rather than Cerrado sensu stricto, in spite of the comparable soil and site characteristics and the proximity of the studied sites. The hypothesis was tested using aerial photographs of 1964, which showed that the cultivated sites were located on a desiccated runoff head. The vegetation shift to a grass-dominated savanna formation might therefore have occurred in response to waterlogging and reduced soil aeration. A simple model was developed thereof, which ascribes the different Cerrado formations mainly to the plant-available water content and soil aeration. Soil fertility is considered of minor significance only, since at the studied native savanna sites tree density was independent of soil texture or nutrient status.

Laboratorio virtual de software libre para bibliotecas

La elección de un programa de gestión de bibliotecas se ve afectada muchas veces por una serie de condiciones sociales, económicas y políticas que hacen que la elección no sea la más adecuada para las necesidades, características y funciones de la biblioteca. El software libre está siendo una de las soluciones más optadas, por sus libertades de copia, modificación y distribución, además de la libertad de licencias y las posibilidades de interoperación con otras aplicaciones. Esta nueva tendencia hacia el software libre en bibliotecas se refleja también en los estudios de biblioteconomía y documentación, en los que desde diferentes asignaturas se aportan conocimientos sobre programas de automatización, de gestión de repositorios, incluso del sistema operativo Linux/GNU, entre otros. Esta combinación entre las necesidades de los centros y la tendencia al uso de software libre, es la que un grupo de profesores de la Facultat de Biblioteconomia i Documentació (Universitat de Barcelona) y estudiantes, miembros del Grup de Treball sobre Programari Lliure per als Professionals de la Informació (Cobdc), han querido aportar a la comunidad profesional, creando un laboratorio virtual para el uso de software libre de aplicación en bibliotecas.
