Cómplices y coautores del hecho : Los múltiples involucrados en un delito sexual. Buenos Aires, 1850-1890

Los crímenes sexuales en general, y la violación en particular, suelen concebirse como una situación que involucra únicamente a dos personas: la víctima y su atacante, entre los que puede o no haber una relación o conocimiento previo. Esta imagen ha cristalizado en la justicia y la sociedad, convirtiéndose en parte del imaginario común. Sin embargo, los expedientes judiciales vinculados a estos delitos nos muestran un universo complejo de actores que no se agotan en aquel par. En este trabajo pretendo concentrarme y analizar casos en los que existe más de un acusado por el mismo crimen, mostrando particularmente cómo la justicia lidia con ellos desde el discurso, utilizando distintos expedientes para analizar las imágenes que jueces, abogados y médicos expresan, afirman o discuten sobre la sexualidad, el comportamiento esperado de los hombres y mujeres y la propia situación de la justicia frente a crímenes que se corren de la "normalidad" reconocida para aquellos

Psicología y delitos de lesa humanidad : Dispositivos de acompañamiento activo. Un aporte posible desde la psicología en los juicios por lesa humanidad

Con la puesta en marcha y desarrollo de los juicios por crímenes de lesa humanidad cometidos durante la última dictadura cívico-militar se inaugura un nuevo espacio de intervención para la psicología. El interés por ampliar y profundizar las posibilidades de trabajar en este campo impulsa a llevar adelante una tarea de investigación, conceptualización y desarrollo acerca de los aportes posibles de la psicología a las problemáticas que plantea el abordaje de las víctimas de los delitos de lesa humanidad en el marco de su tramitación judicial. Se analizará la evolución en el campo jurídico de las variables que permitieron el pasaje de la consideración de los delitos cometidos por el régimen militar a su calificación como delitos de lesa humanidad, condición fundamental que les confiere el carácter de imprescriptibilidad, lo cual habilita el relanzamiento de los juicios por estas causas y la consiguiente osibilidad de intervenir desde nuestra profesión. Para ello será necesario tener en cuenta tanto el análisis de las condiciones de inicio del campo de la salud mental y derechos humanos, como los requerimientos y posibilidades actuales del mismo. En este sentido, se presentará el diseño e implementación de un modelo de Dispositivo de acompañamiento activo dirigido a testigos-víctimas y querellantes en juicios por crímenes de lesa humanidad en contexto de acceso a la justicia

Cómplices y coautores del hecho : Delitos sexuales "en grupo" en la Provincia de Buenos Aires (1863-1903)

Los crímenes sexuales en general, y la violación en particular, suelen concebirse como una situación que involucra únicamente a dos personas: la víctima y su atacante. Sin embargo, los expedientes judiciales vinculados a estos delitos muestran un universo complejo de actores, que no ;se agota en aquel binomio. El presente trabajo se enfoca en algunas de esas ocasiones donde aquella lógica se demuestra incorrecta, mostrando cómo la justicia lidia con aquel desafío desde el discurso jurídico, analizando imágenes y concepciones que abogados y médicos expresan, afirman ;o discuten en relación al comportamiento esperado de hombres y mujeres, así como la situación de la justicia frente a crímenes que se alejan de la "normalidad" reconocida

Contribution to multiuser videoconferencing systems based on cloud computing

Multi-user videoconferencing systems offer communication between more than two users, who are able to interact through their webcams, microphones and other components. The use of these systems has been increased recently due to, on the one hand, improvements in Internet access, networks of companies, universities and houses, whose available bandwidth has been increased whilst the delay in sending and receiving packets has decreased. On the other hand, the advent of Rich Internet Applications (RIA) means that a large part of web application logic and control has started to be implemented on the web browsers. This has allowed developers to create web applications with a level of complexity comparable to traditional desktop applications, running on top of the Operating Systems. More recently the use of Cloud Computing systems has improved application scalability and involves a reduction in the price of backend systems. This offers the possibility of implementing web services on the Internet with no need to spend a lot of money when deploying infrastructures and resources, both hardware and software. Nevertheless there are not many initiatives that aim to implement videoconferencing systems taking advantage of Cloud systems. This dissertation proposes a set of techniques, interfaces and algorithms for the implementation of videoconferencing systems in public and private Cloud Computing infrastructures. The mechanisms proposed here are based on the implementation of a basic videoconferencing system that runs on the web browser without any previous installation requirements. To this end, the development of this thesis starts from a RIA application with current technologies that allow users to access their webcams and microphones from the browser, and to send captured data through their Internet connections. Furthermore interfaces have been implemented to allow end users to participate in videoconferencing rooms that are managed in different Cloud provider servers. To do so this dissertation starts from the results obtained from the previous techniques and backend resources were implemented in the Cloud. A traditional videoconferencing service which was implemented in the department was modified to meet typical Cloud Computing infrastructure requirements. This allowed us to validate whether Cloud Computing public infrastructures are suitable for the traffic generated by this kind of system. This analysis focused on the network level and processing capacity and stability of the Cloud Computing systems. In order to improve this validation several other general considerations were taken in order to cover more cases, such as multimedia data processing in the Cloud, as research activity has increased in this area in recent years. The last stage of this dissertation is the design of a new methodology to implement these kinds of applications in hybrid clouds reducing the cost of videoconferencing systems. Finally, this dissertation opens up a discussion about the conclusions obtained throughout this study, resulting in useful information from the different stages of the implementation of videoconferencing systems in Cloud Computing systems. RESUMEN Los sistemas de videoconferencia multiusuario permiten la comunicación entre más de dos usuarios que pueden interactuar a través de cámaras de video, micrófonos y otros elementos. En los últimos años el uso de estos sistemas se ha visto incrementado gracias, por un lado, a la mejora de las redes de acceso en las conexiones a Internet en empresas, universidades y viviendas, que han visto un aumento del ancho de banda disponible en dichas conexiones y una disminución en el retardo experimentado por los datos enviados y recibidos. Por otro lado también ayudó la aparación de las Aplicaciones Ricas de Internet (RIA) con las que gran parte de la lógica y del control de las aplicaciones web comenzó a ejecutarse en los mismos navegadores. Esto permitió a los desarrolladores la creación de aplicaciones web cuya complejidad podía compararse con la de las tradicionales aplicaciones de escritorio, ejecutadas directamente por los sistemas operativos. Más recientemente el uso de sistemas de Cloud Computing ha mejorado la escalabilidad y el abaratamiento de los costes para sistemas de backend, ofreciendo la posibilidad de implementar servicios Web en Internet sin la necesidad de grandes desembolsos iniciales en las áreas de infraestructuras y recursos tanto hardware como software. Sin embargo no existen aún muchas iniciativas con el objetivo de realizar sistemas de videoconferencia que aprovechen las ventajas del Cloud. Esta tesis doctoral propone un conjunto de técnicas, interfaces y algoritmos para la implentación de sistemas de videoconferencia en infraestructuras tanto públicas como privadas de Cloud Computing. Las técnicas propuestas en la tesis se basan en la realización de un servicio básico de videoconferencia que se ejecuta directamente en el navegador sin la necesidad de instalar ningún tipo de aplicación de escritorio. Para ello el desarrollo de esta tesis parte de una aplicación RIA con tecnologías que hoy en día permiten acceder a la cámara y al micrófono directamente desde el navegador, y enviar los datos que capturan a través de la conexión de Internet. Además se han implementado interfaces que permiten a usuarios finales la participación en salas de videoconferencia que se ejecutan en servidores de proveedores de Cloud. Para ello se partió de los resultados obtenidos en las técnicas anteriores de ejecución de aplicaciones en el navegador y se implementaron los recursos de backend en la nube. Además se modificó un servicio ya existente implementado en el departamento para adaptarlo a los requisitos típicos de las infraestructuras de Cloud Computing. Alcanzado este punto se procedió a analizar si las infraestructuras propias de los proveedores públicos de Cloud Computing podrían soportar el tráfico generado por los sistemas que se habían adaptado. Este análisis se centró tanto a nivel de red como a nivel de capacidad de procesamiento y estabilidad de los sistemas. Para los pasos de análisis y validación de los sistemas Cloud se tomaron consideraciones más generales para abarcar casos como el procesamiento de datos multimedia en la nube, campo en el que comienza a haber bastante investigación en los últimos años. Como último paso se ideó una metodología de implementación de este tipo de aplicaciones para que fuera posible abaratar los costes de los sistemas de videoconferencia haciendo uso de clouds híbridos. Finalmente en la tesis se abre una discusión sobre las conclusiones obtenidas a lo largo de este amplio estudio, obteniendo resultados útiles en las distintas etapas de implementación de los sistemas de videoconferencia en la nube.

La evolución de los periódicos digitales frente a los convencionales como soporte publicitario

Research performed in this thesis studies the growth and evolution of advertising investment in digital media compared to traditional printed media, in particular daily newspapers. By means of advertising inserts in printed newspaper and online newspapers, the study’s objective was to confirm that digital media consolidate as an advertising platform. Throughout this study we used different quantitative and qualitative tools to demonstrate the starting hypothesis of this thesis. We used a combined methodology that included: a) joint analysis of printed newspaper “El Mundo” and online newspaper “elmundo.es” advertising content; b) analysis of advertising investment state-of-the-art; c) deep interviews to different media professionals, including advertisers, publicists, media planning, and researchers. A comparative study between the printed newspaper “El Mundo” and the online newspaper “elmundo.es” supported the analysis of contents in a realistic situation. Therefore a deep study of advertising inserts in both the printed and online version of “El Mundo” was performed. The main goal of this work was to show how advertising invesment is moving from traditional printed media to digital media The results of this study reveal that investment in digital media increases, meanwhile investment reduces in traditional media. At the same time, new reading habits along with technological innovation attracts readers to digital platforms. As a consequence, traditional printed newspapers have the immediate need to somehow engage online-newspaper readers into printed platforms. Hence, many advertisers already invest large sums of money in digital media, with marketing strategies and plans focused to online advertising campaigns in Internet. It is also true that in recent years printed and online media stopped “fighting”, which lead to the possibility of joint marketing and communication strategies between the aforementioned digital and online media. This research has different implications, one of them is that printed media seems to be a bussiness model which needs to be reinvented to adapt itself to the media’s current situation in order to be profitable and not to disappear. On the other hand, digital media must have a well-defined strategy with concrete and viable goals in online investment. Finally, it is important that new readers are taken into account by newspapers, this is: new readers mostly use digital platforms, thus interaction between readers and newspapers is much different than what it used to be when only printed newspapers existed. Media must go and be where the new reader is.

Los medios online y la ¿crisis? de la planificación de medios publicitarios

Los medios online representan actualmente una gran apuesta para la publicidad. Desde la planificación de medios publicitarios, los nuevos medios ofrecen otros caminos para llegar al público, pero añaden mayor complejidad. La capacidad comunicativa de los medios online y el mayor consumo de esos medios por parte de la población abre el debate de la necesidad de replantear el enfoque de la planificación de medios, digamos, tradicional, cuya estructura y procesos de trabajo se desarrollaron cuando los medios eran offline. Así, este artículo proporciona una panorámica general de la influencia de los nuevos medios en la planificación. Para ello, en primer lugar, describe el escenario actual, analizando la penetración y las inversiones publicitarias en Internet. Además, expone los principales soportes online según su proximidad a la concepción de la planificación de medios offline. En segundo lugar, aborda los retos actuales en la medición de los nuevos medios como síntoma del impulso del cambio de modelo. Finalmente, el artículo termina exponiendo algunas tendencias que se presentan como motores de cambio. Sin embargo, tras este análisis se advierte que tales aspectos no modificarían la esencia de la planificación de medios, por lo que cabe cuestionarse si se puede hablar de crisis, o si los nuevos medios están mostrando la necesidad de que la investigación y planificación se comprometa con este nuevo escenario.

Online Media and Crisis? of Advertising Media Planning

Nowadays, online media represent a great choice for advertising. From de advertising media planning, new media give new ways to reach the consumers, but they also add more complexity. The communication capacity of online media and the greater use of that media by part of the users open up the debate about the necessity of rethinking the approach of the ‘traditional’ advertising media planning, which structure and work processes were developed when media were offline. So, this article gives a panoramic view about the influence of new media in advertising media planning. To do this, in first place, describes the current scenario, analyzing the penetration and advertising expenditure in Internet. Also, it shows the main online media according to their proximity to the offline advertising media planning conception. In second place, this article addresses the current challenges at measuring new media as a symptom of the impulse at the change of model. Finally, the article ends up showing some trends that are presented as drivers of change. However, after this analysis, comes up the point that those aspects would not change the essence of advertising media planning, so it is questionable if we can speak of a crisis or, instead, if new media are showing the necessity that media planning have to be involved with this new scenario.

Searching for harm or harming search? A look at the European Commission’s antitrust investigation against Google. CEPS Special Report No. 118/September 2015

As the European Commission’s antitrust investigation against Google approaches its final stages, its contours and likely outcome remain obscure and blurred by a plethora of nonantitrust-related arguments. At the same time, the initial focus on search neutrality as an antitrust principle seems to have been abandoned by the European Commission, in favour of a more standard allegation of ‘exclusionary abuse’, likely to generate anticompetitive foreclosure of Google’s rivals. This paper discusses search neutrality as an antitrust principle, and then comments on the current investigation based on publicly available information. The paper provides a critical assessment of the likely tests that will be used for the definition of the relevant product market, the criteria for the finding of dominance, the anticompetitive foreclosure test and the possible remedies that the European Commission might choose. Overall, and regardless of the outcome of the Google case, the paper argues that the current treatment of exclusionary abuses in Internet markets is in urgent need of a number of important clarifications, and has been in this condition for more than a decade. The hope is that the European Commission will resist the temptation to imbue the antitrust case with an emphasis and meaning that have nothing to do with antitrust (from industrial policy motives to privacy, copyright or media law arguments) and that, on the contrary, the Commission will devote its efforts to sharpening its understanding of dynamic competition in cyberspace, and the tools that should be applied in the analysis of these peculiar, fast-changing and often elusive settings.

MP-OWA: the most preferred OWA operator

In practical term any result obtained using an ordered weighted averaging (OWA) operator heavily depends upon the method to determine the weighting vector. Several approaches for obtaining the associated weights have been suggested in the literature, in which none of them took into account the preference of alternatives. This paper presents a method for determining the OWA weights when the preferences of alternatives across all the criteria are considered. An example is given to illustrate this method and an application in internet search engine shows the use of this new OWA operator.

E-satisfaction:a re-examination

E-satisfaction as a construct has gained increasing importance in the marketing literature in recent times. The examination of consumer satisfaction in an online context follows the growing consensus that in Internet retailing, as in traditional retailing, consumer satisfaction is not only a critical performance outcome, but also a primary predictor of customer loyalty and thus, the Internet retailer's endurance and success. The current study replicates the initial examination of e-satisfaction within the U.S. by [Szymanski, David M., & Richard T. Hise (2000). E-satisfaction: An initial examination. Journal of Retailing, 76(3), 309–322] among a sample of online consumers drawn from Germany. The replication was extended to two contexts—consumer satisfaction with Internet retail shopping and consumer satisfaction with Internet financial services sites. The results yield rich insights into the validity of extending the measurement and predictors of e-satisfaction to a trans-national context.

Strategic marketing and e-business

The dramatic growth in e-business is manifest in phenomena such as the surge in internet retailing, the boom in social media based marketing communications, and the centrality of e-commerce to many organizations’ core strategies. Despite this the precise implications of e-business for marketing strategy remain little-understood. In order to guide theory development and practice in the marketing strategy domain, it is of fundamental importance to take stock of the impact that e-business has had upon strategic marketing. Therefore, this chapter develops a conceptual framework in order to explicate the implications of e-business for strategic marketing theory and practice. We find that the impact of e-business on strategic marketing is far-reaching; influencing not only isolated departments, but the organization as a whole. Finally, we conclude that whilst organizations should be alert to the dynamic opportunities and threats posed by e-business, the guiding principle of value creation should not be forgotten.

Automatic Creation of Lexical Resources for an Interlingua-based System

The Universal Networking Language (UNL) is an interlingua designed to be the base of several natural language processing systems aiming to support multilinguality in internet. One of the main components of the language is the dictionary of Universal Words (UWs), which links the vocabularies of the different languages involved in the project. As any NLP system, coverage and accuracy in its lexical resources are crucial for the development of the system. In this paper, the authors describes how a large coverage UWs dictionary was automatically created, based on an existent and well known resource like the English WordNet. Other aspects like implementation details and the evaluation of the final UW set are also depicted.

Bridging the Gap Between Human Language and Computer-Oriented Representations

Information can be expressed in many ways according to the different capacities of humans to perceive it. Current systems deals with multimedia, multiformat and multiplatform systems but another « multi » is still pending to guarantee global access to information, that is, multilinguality. Different languages imply different replications of the systems according to the language in question. No solutions appear to represent the bridge between the human representation (natural language) and a system-oriented representation. The United Nations University defined in 1997 a language to be the support of effective multilinguism in Internet. In this paper, we describe this language and its possible applications beyond multilingual services as the possible future standard for different language independent applications.

The discrimination and association of float glass and the quantitative analysis of liquids from aerosols and microdrops using laser induced breakdown spectroscopy

Glass is a common form of trace evidence found at many scenes of crimes in the form of small fragments. These glass fragments can transfer to surrounding objects and/or persons and may provide forensic investigators valuable information to link a suspect to the scene of a crime. Since the elemental composition of different glass sources can be very similar, a highly discriminating technique is required to distinguish between fragments that have originated from different sources. ^ The research presented here demonstrates that Laser Induced Breakdown Spectroscopy (LIBS) is a viable analytical technique for the association and discrimination of glass fragments. The first part of this research describes the optimization of the LIBS experiments including the use of different laser wavelengths to investigate laser-material interaction. The use of a 266 nm excitation laser provided the best analytical figures of merit with minimal damage to the sample. The resulting analytical figures of merit are presented. The second part of this research evaluated the sensitivity of LIBS to associate or discriminate float glass samples originating from the same manufacturing plants and produced at approximately the same time period. Two different sample sets were analyzed ranging in manufacturing dates from days to years apart. Eighteen (18) atomic emission lines corresponding to the elements Sr, K, Fe, Ca, Al, Ba, Na, Mg and Ti, were chosen because of their detection above the method detection limits and for presenting differences between the samples. Ten elemental ratios producing the most discrimination were selected for each set. When all the ratios are combined in a comparison, 99% of the possible pairs were discriminated using the optimized LIBS method generating typical analytical precisions of ∼5% RSD. ^ The final study consisted of the development of a new approach for the use of LIBS as a quantitative analysis of ultra-low volume solution analysis using aerosols and microdrops. Laser induced breakdown spectroscopy demonstrated to be an effective technique for the analysis of as low as 90 pL for microdrop LIBS with 1 pg absolute LOD and 20 µL for aerosol LIBS with an absolute LOD of ∼100 fg.^
