Primeras evidencias de arte mueble paleolítico en el sur de Portugal
Simón Vallejo, María D.,Cortés Sánchez, Miguel,Bicho, Nuno
Trabajos de Prehistoria , 2012, DOI: 10.3989/tp.2012.12076
Abstract: This paper presents the first evidence for Palaeolithic portable art in Southern Portugal. This include two plaques, dated between 20,500 and 19,500 BP from Solutrean levels from the site of Vale Boi, Western Algarve (Portugal). One of the pieces is a small engraved schist plaque (14,6 × 8,1 mm) with abstract lines on one side. The other artefact is an 8 × 5 cm schist plaque. One side is an oxide natural deposit, used to produce dye; the other side has three aurochs and a probable cervid. Stilistic information and the engraving sequence indicate probably production by a single artist. The stylistic characteristics are in full agreement withi those from late Gravettian and early Solutrean art known from Valencia, Andalucia (Spain) and the C a valley (Portugal), thus confirming the absolute AMS dates from the Vale Boi Levels. En este trabajo presentamos la primera evidencia de arte mueble paleolítico en el sur de Portugal: dos plaquetas de pizarra procedentes de niveles solutrenses del yacimiento de Vale Boi, zona occidental del Algarve (Portugal). La primera de las piezas es una peque a placa (14,6 × 8,1 mm) que presenta sobre una de sus caras un ideomorfo grabado. La segunda (8 × 5 cm) cuenta con una superficie ocupada por óxido de hierro natural de color amarillento, tiene claros indicios de extracción de mineral para producir colorantes. En la superficie opuesta han sido grabados tres uros y una posible cierva. El estilo y secuencia de los grabados apuntan a un solo artista. Las características estilísticas de los zoomorfos concuerdan bien con los rasgos comunes del arte del ciclo Gravetiense final y Solutrense antiguo del País Valenciano, Andalucía y Valle de C a (Portugal). Esta afinidad sintoniza asimismo con las fechas AMS de los niveles solutrenses de Vale Boi, datados entre ca. 20.500 y 19.500 BP.

Abstract: OBJETIVOS: determinar las características del hábito del tabaquismo en los profesores de las diferentes especialidades clínicas y quirúrgicas de la Facultad de Medicina de la Universidad de Antioquia en el a o 2006. Establecer la influencia del conocimiento médico sobre el hábito de fumar e identificar si hay educación por parte del médico a sus pacientes con miras a disminuir el consumo de tabaco. MéTODOS: se realizó un estudio descriptivo exploratorio de tipo transversal, mediante el análisis de encuestas respondidas por médicos especialistas, profesores de la Facultad de Medicina de la Universidad de Antioquia. RESULTADOS: en total se encuestó a 243 docentes. De ellos, 121 (49,8%) habían fumado en alguna oportunidad y 122 (50,2%) nunca lo habían hecho. De los 121 docentes que habían fumado en alguna oportunidad, 29 (24,0%) seguían fumando al momento de la encuesta. Al explorar la relación entre el consumo de tabaco y las variables sexo, edad, especialidad agrupada como clínica o quirúrgica y horas de trabajo como docente no se encontraron diferencias estadísticamente significativas. Del total de los médicos encuestados, 190 (78,2%) les preguntaban rutinariamente a sus pacientes si fumaban y, en caso afirmativo, 137 (72,1%) siempre les sugerían que lo dejaran pues lo consideran un hábito inadecuado. De los docentes encuestados, 121 (49,8%) consideraron que sus conocimientos médicos sí habían influido en el hábito de fumar y 122 (50,2%) consideraron que no. CONCLUSIONES: en Colombia el 19,8% de la población general es fumadora; el estudio realizado demostró una prevalencia mayor entre el grupo encuestado de profesionales de la salud. Se requiere implementar estrategias desde la formación profesional y de educación continuada que motiven al médico a prevenir y controlar el tabaquismo en él y en sus pacientes.

Munibe Antropologia-Arkeologia , 2005,
Abstract: La Cueva de Nerja constituye uno de los principales yacimientos arqueológicos para el conocimiento del Paleolítico Superior en el sur de la Península Ibérica. Entre 1962 y 1963 se llevó a cabo una excavación sistemática sobre 14 metros cuadrados de la Sala del Vestíbulo, en la que se documentó una amplia secuencia con ocupaciones del Paleolítico Superior, Epipaleolitico y Neolítico. No obstante, los materiales recuperados en las citadas intervenciones permanecían por diversas circunstancias sin estudiar. En este trabajo abordamos la colección de mamíferos porvedentes de los tres niveles solutrenses, comprendidos cronológicamente entre c. 20-17.5 ka B.P., rango cronológico del cual apenas contamos con registros bien publicados en el contexto meridional peninsular.
Determining the specific status of the Iberian sturgeons by means genetic analyses of old specimens  [PDF]

Abstract: To clarify the species status of sturgeon from rivers of the Iberian Peninsula, eight molecular markers (4 nuclear and 4 mitochondrial) have been analysed in different specimens from historical museum samples and prehistoric samples from archaeological sites. These analyses indicate that one of these specimens (UGP captured in the Guadalquivir River in the 19th century) is A. sturio, based on all the eight molecular markers, four of them used from the first time in this study. In previous analyses based on 5 genetic markers, our group assigned two specimens captured in this river in the 1970-80s (EBD8173 and EBD8401) to the species A. naccarii, suggesting the presence of this species in the Iberian Peninsula. In this work, this conclusion is drawn after successfully obtaining a mitochondrial marker in a very old scute from a prehistoric site (Acinipo, about 1500 BC, from the Guadalquivir River basin). On the other hand, in the specimen EBD8174 captured in the Guadalquivir in 1975, we have obtained two new mitochondrial markers confirming that it can be considered A. sturio for all the mitochondrial markers, but nuclear ones identify it as A. naccarii. Finally, two very old samples (Nerja E-VI and Nerja N/62-63) were not successfully characterized by any molecular markers. Some aspects and consequences of our results are discussed, such as the origin of the “mosaic” specimen EBD8174 and, above all, the native status of A. naccarii in historic and prehistoric times in the southern Iberian Peninsula.

El problema de la consanguinidad en la medicina francesa (1850- 1880): cuando heredar demasiado era un riesgo y un deseo
Vallejo, Mauro Sebastián
Asclepio : Revista de Historia de la Medicina y de la Ciencia , 2012,
Abstract: This paper handles the problem of consanguinity in French medicine of the second half of 19th century. During a few years, French doctors were very concerned about the issue of marriages between close relatives. Many thesis, articles and books were completely dedicated to describe the consequences of those marriages over offspring. This article analyzes the two most important theories about that new chapter of medicine. El presente trabajo aborda el problema de la consanguinidad en la medicina francesa de la segunda mitad del siglo XIX. En el transcurso de unos pocos a os, el asunto de los matrimonios entre parientes cercanos acaparó fuertemente la atención de los profesionales de ese país. Múltiples tesis, artículos y tratados fueron enteramente dedicados a describir los efectos de tales uniones sobre la descendencia. Se reconstruyen aquí las dos teorías más importantes construidas respecto de ese nuevo capítulo del saber médico.
Importance of the market portfolio description in the assessment of a sample of Spanish investment funds through the Jensen’s Alpha

Cuadernos de Gestión , 2003,
Abstract: The right assessment of the investment funds performance and of the manager’s ability to add value with their management is an important aspect to which has been paid special attention. Among the traditional performance measures, one of the most used is the Jensen’s alpha. However, one of the main problems of the evaluation methods using the beta as a risk measure and, hence of the Jensen’s alpha, is their sensibility to the market portfolio. In this work we aim to study the importance of the market portfolio description in the assessment of a sample of Spanish investment funds through the Jensen’s alpha. We analyze the market portfolio influence, on the one hand, in the alpha outcomes and, on the other, in the ranking of the funds that they provide.
Attitudes of University Students to Some Verbal Anti-Sexist Forms  [PDF]
Mercedes Bengoechea, José Simón
Open Journal of Modern Linguistics (OJML) , 2014, DOI: 10.4236/ojml.2014.41008
Abstract:

After more than two decades of non-sexist linguistic policies in Spain, a survey was carried out to evaluate the positive or negative attitude of almost 500 students from two Madrid universities to the most controversial verbal forms advocated in Spanish non-sexist linguistic policies: 1) the use of @ (as in alumn@s [students]); 2) the use of dual gender (as in alumnos y alumnas [students- masc and students-fem]); 3) the use of feminine terms for some women’s professional titles and occupations (i.e. ingeniera [engineer-fem], bedela [caretaker-fem], arquitecta [architect-fem], médica [physician-fem], aparejadora [quantity surveyor-fem], gerenta [manager-fem], perita [ex- pert-fem], cancillera* [chancellor-fem]); 4) the use of non-sexed collective nouns (as in profeso- rado [teaching staff]). Our aims were to know to what degree these resources were accepted by highly-educated young people, whether differences exist between the attitudes of men and women with respect to these forms, and which of these uses was the best accepted and which the least. Various examples of these non-sexist uses were presented to university students, who were asked to make a pronouncement on the feeling which these gave them or whether they used them. Our study concluded that the @ symbol and collective nouns are widely accepted among the student community. The dual gender seems to be also accepted, although greater vacillation was seen and sometimes the levels of rejection or indifference are higher. Nevertheless, of the four uses studied, the one which appears to provoke the greatest hesitation, vacillation or even opposition is the use of the feminine for some names of professions. In general, the number of female students in favour of the four features studied exceeds the number of male students.

Del individuo aislado a la comunidad cohesionada: Los límites a la libertad en Rawls y Aron
Garzón Vallejo,Iván;
Civilizar Ciencias Sociales y Humanas , 2009,
Abstract: the theoretical development of john rawls and raymond aron highlights a liberalism that acknowledges as its starting point the individual being free and isolated, which, because of the influence of internal and external constraints on individual liberties, encourages the construction of a cohesive political community. with such a perspective challenges the modern version of liberty as an absence of coercion and, at the same time, highlights the validity of the discussion about the limits of liberty in contemporary societies. this phenomenon can be described as the transition from liberalism to social democracy, or as revision of the negative conception of individual liberties.
