    Acoso psicológico, organización e identidad : análisis desde un foro virtual

    Get PDF
    Las interacciones que tienen lugar en los foros de discusión de Internet se vienen empleando como fuente de información para el análisis de distintas temáticas sociales. Estos foros constituyen en muchos casos un nexo de (re)unión para las comunidades de afectados por problemas de distinta índole, convirtiéndose así el ciberespacio en un marco referencial para el estudio de los mismos. Por otro lado, la disponibilidad de los discursos íntegros de los participantes en estos foros y el carácter textual de los contenidos incluidos facilitan el empleo de metodologías de tipo cualitativo para el análisis de los fenómenos. En el presente trabajo analizamos el acoso psicológico en el marco de los foros de Internet con el objeto de profundizar en sus implicaciones subjetivas, especialmente los aspectos relacionados con la formulación de las identidades; y en sus implicaciones organizacionales, centrando la atención en las dimensiones estructurales y funcionales.Interactions in internet discussion forums provide data on a variety of social issues. Forums are often a meetingplace for people affected by a given problem; in fact, cyberspace has become a framework of reference in the study of such interaction. The ready availability of the participants' discourse, and the textual nature of the forum's contents, facilitate the use of qualitative methodologies. The present article analyses harassment in internet forums in order to study its subjective implications, specially those aspects related to the formulation of participants' identities. The article also explores the organizational implications of harassment, focusing on its structural and functional dimensions

    <p>Abstract</p> <p>Background</p> <p><it>Rhizobium</it>-Legume symbiosis is an attractive biological process that has been studied for decades because of its importance in agriculture. However, this system has undergone extensive study and although many of the major factors underpinning the process have been discovered using traditional methods, much remains to be discovered.</p> <p>Results</p> <p>Here we present an analysis of the 'Symbiosis Interactome' using novel computational methods in order to address the complex dynamic interactions between proteins involved in the symbiosis of the model bacteria <it>Sinorhizobium meliloti </it>with its plant hosts. Our study constitutes the first large-scale analysis attempting to reconstruct this complex biological process, and to identify novel proteins involved in establishing symbiosis. We identified 263 novel proteins potentially associated with the Symbiosis Interactome. The topology of the Symbiosis Interactome was used to guide experimental techniques attempting to validate novel proteins involved in different stages of symbiosis. The contribution of a set of novel proteins was tested analyzing the symbiotic properties of several <it>S. meliloti </it>mutants. We found mutants with altered symbiotic phenotypes suggesting novel proteins that provide key complementary roles for symbiosis.</p> <p>Conclusion</p> <p>Our 'systems-based model' represents a novel framework for studying host-microbe interactions, provides a theoretical basis for further experimental validations, and can also be applied to the study of other complex processes such as diseases.</p

    Fish abundance estimation with imaging sonar in semi-intensive aquaculture ponds

    To know the abundance of fishes and their size distribution in the semi-intensive rearing systems in traditional ponds is an aspect key to plan and manage efficiently the sales lots. Usually this information is obtained by means of sampling which mandatory supposes a direct catch and stressful and time consuming management of fishes. Therefore, in this work we propose the use of non-invasive procedures based on multibeam sonars or imaging sonars to count and size the fishes in the ponds. For that, we use a commercial technology portable-fixed multibeam imaging sonar and estimate the abundance in ponds of a gilt-head seabream (Sparus aurata) fishfarm from sonar image analysis and adapting statistical methodologies traditionally applied for bird abundance estimation. Additionally, a simulation software was developed to emulate the fish aggregation contained in the rearing ponds. This computer program allows the calculation of an abundance correction factor which depends on the transducer beam size in relation to the pond size. The results indicate that the estimation is as accurate as the obtained by the fishfarm manager using traditional sampling methods and additionally it is possible to obtain a realistic function of the size distribution which allows estimate the biomass by size contained in the rearing ponds.This work was supported by KTTSeaDrones project (0622_KTTSEADRONES_5_E), cofunded by the European Regional Development Fund, ERDF, through the Interreg V-A Spain-Portugal program (POCTEP) 2014–2020.

    ECOS-LINCE : a high-intensity heavy-ion facility for nuclear structure and reactions

    Presented at the XXXIV Mazurian Lakes Conference on Physics, Piaski, Poland, September 6–13, 2015During the last years, the ECOS working group has been considering the construction of a new high-intensity accelerator of stable ion beams for the next Long-Range Plan of the nuclear physics community in Europe. The new facility (LINCE) will be a multi-user facility dedicated to ECOS science: fundamental physics, astrophysics, nuclear structure and reaction dynamics. In this paper, we summarize preliminary design studies of the low-energy part of this facility based on the use of a multi-ion supercon- ducting linac.Work partially supported by the Spanish Government under the grant Feder-Interconnecta “Aceltec” ITC-20111070. The authors are also grateful to the companies Alter Technology-Tüv, Avs, Cibernos, Elitt Energy, Faysol, Idom, and Tti Norte for partial funding of this work and active participation in the design and prototyping carried-out in this study

    Recruits in Slovenskí Branci: Reasons for joining.

    No full text
    The present paper is part of a larger research project that looked at the reality of the paramilitary phenomenon in Eastern Europe (Slovakia), in particular at the influence of the so-called “refugee crisis” on the creation and maintenance of paramilitary groups in the country. This paper introduces the Slovenskí Branci (Slovak Recruits) unit as a case study of the motivations of recruits to engage in paramilitary activities. The recruits’ reasons, as well as the attraction of violence and the perceived need for social defense will be studied here. With respect to methodology, the analysis is conducted from the point of view of cultural criminology. The research question for this paper is “Why have recruits in Slovenskí Branci decided to join the paramilitary group?”. Overall, the reasons given by the recruits for participating in paramilitary activities can be divided into the need to defend the homeland against perceived invaders, based on nationalism and ontological insecurity, and the attractiveness of militarism for the people involved in the group
