Matrimonios en crisis y respuestas legales : el divorcio unilateral o de común acuerdo en el derecho ateniense

Existe una creencia generalizada de que planteos que son propios del discurso actual del derecho de familia, como el que distingue un divorcio unilateral de uno por consenso, responden a una realidad contemporánea. El objetivo de este trabajo consiste en descubrir primero las particularidades del derecho ático, que se presenta como un sistema jurídico diferente del que hoy conocemos. Así, a partir de estas nociones y del análisis de distintos pasajes literarios del período clásico en que hallamos referencias al divorcio, se discute si efectivamente encontramos en aquella época una ruptura del vínculo matrimonial que se impone como sanción a uno de los cónyuges, frente a otra, por otro lado, que se pacta en términos cordiales entre marido y mujer. Esta re-lectura de los textos permite poder así encarar desde otro lugar nuestra realidad jurídica actual y echar luz sobre algunos aspectos aún bastante discutidos del régimen jurídico ateniense.There's a general idea that most notions which are stated through new tendencies in family law, as that idea of distinguishing unilateral divorce from a marriage dissolution agreed by husband and wife, are born as an updating response to modern problems. The first purpose of this paper is to discover the main characteristics of Attic Law, which should be conceived as a plainly different juridical system than ours. It will be discussed then whether these concepts and the analysis of literary passages from Classical times dealing with divorce allow us to find a difference between the breaking of marriage contract coming as a punishment for one of the parts, on one side, and a divorce friendly established by both man and woman, on the other. Revisiting these texts will help us think of our own legal institutions and to enlighten some aspects about Athenian regime which still seem to be under discussion

Los varones atenienses y el coro de ciudades aliadas en Póleis de Éupolis

Esta ponencia procurará examinar los fragmentos de la obra Póleis de Éupolis desde el contrapunto entre violencia y sometimiento, entre vigores y debilidades, que es propio de la concepción griega de las diferencias de género. Las múltiples referencias de los pasajes preservados a la política exterior en clave sexual son capaces de develar las relaciones de dominación en tanto enfrentamiento de la agresión 'masculinizada' de los Estados hegemónicos como Atenas y la impotencia 'afeminada' de las naciones oprimidas. En la obra los integrantes del coro están representados por las distintas ciudadesEstado aliadas de Atenas durante la Guerra del Peloponeso. Esas imágenes femeninas sirven para identificar variados perfiles que permiten pensar en las graves consecuencias políticas del sometimiento imperial

Fibre laser hydrophones for cosmic ray particle detection

The detection of ultra high energetic cosmic neutrinos provides a unique means to search for extragalactic sources that accelerate particles to extreme energies. It allows to study the neutrino component of the GZK cut-off in the cosmic ray energy spectrum and the search for neutrinos beyond this limit. Due to low expected flux and small interaction cross-section of neutrinos with matter large experimental set-ups are needed to conduct this type of research. Acoustic detection of cosmic rays may provide a means for the detection of ultra-high energetic neutrinos. Using relative low absorption of sound in water, large experimental set-ups in the deep sea are possible that are able to detect these most rare events, but it requires highly sensitive hydrophones as the thermo-acoustic pulse originating from a particle shower in water has a typical amplitude as low as a mPa. It has been shown in characterisation measurements that the fibre optic hydrophone technology as designed and realised at TNO provides the required sensitivity. Noise measurements and pulse reconstruction have been conducted that show that the hydrophone is suited as a particle detector.Comment: Submitted to the proceedings of "13th Topical Seminar on Innovative Particle and Radiation Detectors (IPRD13)

The effect of spatial, spectral and radiometric factors on classification accuracy using thematic mapper data

An experiment of a factorial design was conducted to test the effects on classification accuracy of land cover types due to the improved spatial, spectral and radiometric characteristics of the Thematic Mapper (TM) in comparison to the Multispectral Scanner (MSS). High altitude aircraft scanner data from the Airborne Thematic Mapper instrument was acquired over central California in August, 1983 and used to simulate Thematic Mapper data as well as all combinations of the three characteristics for eight data sets in all. Results for the training sites (field center pixels) showed better classification accuracies for MSS spatial resolution, TM spectral bands and TM radiometry in order of importance

Banquetes togados: el imaginario romano del "symposion" en los fragmentos cómicos de Titinio, Afranio y Atta

Recientemente, Dupont (2005a) ha demostrado de qué modo la comedia palliata introduce en escena una "otredad" que, lejos de provenir de sus orígenes extranjeros, el propio texto crea desde su lógica compositiva. Su noción de "alterité incluse", desde esta perspectiva, es útil para explicar en el género cómico toda una serie de alusiones al mundo griego originadas en la propia cosmovisión de los romanos, y esto se advierte especialmente en lo que se refiere al universo de los placeres. Ante esta reflexión, nos propusimos pensar si es posible validar este marco teórico a partir de los testimonios de aquella vertiente cómica republicana que, frente a la tradición helenística, se caracteriza por su argumento local: nos referimos a la comoedia togata. En este artículo nos proponemos examinar en qué términos se produce la construcción textual del banquete en el seno de la fa bula togata

Mapping the Spatio-temporal Distribution of Key Vegetation Cover Properties in Lowland River Reaches, Using Digital Photography

The presence of vegetation in stream ecosystems is highly dynamic in both space and time. A digital photography technique is developed to map aquatic vegetation cover at species level, which has a very-high spatial and a flexible temporal resolution. A digital single-lens-reflex (DSLR) camera mounted on a handheld telescopic pole is used. The low-altitude (5 m) orthogonal aerial images have a low spectral resolution (Red-Green-Blue), high spatial resolution (~1.9 pixels cm-2, ~1.3 cm length) and flexible temporal resolution (monthly). The method is successfully applied in two lowland rivers to quantify four key properties of vegetated rivers: vegetation cover, patch size distribution, biomass and hydraulic resistance. The main advantages are that the method is: (i) suitable for continuous and discontinuous vegetation covers (ii) of very-high spatial and flexible temporal resolution, (iii) relatively fast compared to conventional ground survey methods, (iv) non-destructive, (v) relatively cheap and easy to use, and (vi) the software is widely available and similar open source alternatives exist. The study area should be less than 10 m wide and the prevailing light conditions and water turbidity levels should be sufficient to look into the water. Further improvements of the images processing are expected in the automatic delineation and classification of the vegetation patches

Evaluating Active U: an Internet-mediated physical activity program.

Background: Engaging in regular physical activity can be challenging, particularly during the winter months. To promote physical activity at the University of Michigan during the winter months, an eight-week Internet-mediated program (Active U) was developed providing participants with an online physical activity log, goal setting, motivational emails, and optional team participation and competition. Methods: This study is a program evaluation of Active U. Approximately 47,000 faculty, staff, and graduate students were invited to participate in the online Active U intervention in the winter of 2007. Participants were assigned a physical activity goal and were asked to record each physical activity episode into the activity log for eight weeks. Statistics for program reach, effectiveness, adoption, and implementation were calculated using the Re-Aim framework. Multilevel regression analyses were used to assess the decline in rates of data entry and goal attainment during the program, to assess the likelihood of joining a team by demographic characteristics, to test the association between various predictors and the number of weeks an individual met his or her goal, and to analyze server load. Results: Overall, 7,483 individuals registered with the Active U website (≈16% of eligible), and 79% participated in the program by logging valid data at least once. Staff members, older participants, and those with a BMI < 25 were more likely to meet their weekly physical activity goals, and average rate of meeting goals was higher among participants who joined a competitive team compared to those who participated individually (IRR = 1.28, P < .001). Conclusion: Internet-mediated physical activity interventions that focus on physical activity logging and goal setting while incorporating team competition may help a significant percentage of the target population maintain their physical activity during the winter months
