The objective of this article is to work the media representation of citizens＇ rights in television news. We have taken a particular case which happened in the province and the autonomous City of Buenos Aires, Argentina during the second week of December 2010. Such circumstances were in opposition to housing rights and property. We selected a sample of three evening news （two private and one public） Telenoche, Telefe News, and Vision 7, with the intention of establishing a line of comparison in both media, and thereby recognizing the differences in patterns of representation the news. From the analysis of data, we realize the ways in which TV News defined the citizen complaint.

This paper is focused on the analysis, in the framework of lattice theory, of the matchings obtained from restabilization (after disruption) of stable matchings. When the disruption is due to entry workers or closure of firms the unemployed workers make offers to firms. The stable matching obtained is the firms-worst stable matching of the set of stable matchings that the firms weakly prefer to the initial stable matching (i.e., before being disrupted by changes in the population). More precisely, their position within the lattice of stable matchings is shown.

An important characteristic of fractured rocks is their high seismic attenuation, which so far has been mainly attributed to wave-induced fluid flow（WIFF） between the fractures and the embedding matrix. The influence of fracture connectivity on seismic attenuation has, however, recently, only been investigated. Numerical compressibility and shear tests based on Biot＇s quasi-static poro-elastic equations illustrate that an important manifestation of WIFF arises in the presence of fracture connectivity. The corresponding energy loss, which can be significant for both P- and S-waves, is mainly due to fluid flow within the connected fractures and is sensitive to the permeabilities as well as the lengths and intersection angles of the fractures. Correspondingly, this phenomenon contains valuable information on the governing hydraulic properties of fractured rocks and hence should be accounted for whenever realistic seismic models of such media are needed.

We consider linear partial differential equations of first order on a region . We will see that we can write the equation in partial derivatives as an Fredholm integral equation of the first kind and will solve this latter with the techniques of inverse problem moments. We will find an approximated solution and bounds for the error of the estimated solution using the techniques on problem of moments.

Dear Editor The NAC （for NO APICAL MERISTEM [NAM], Arabidopsis TRANSCRII^TION ACTIVATOR FACTOR [ATAF] and CUP- SHAPED COTYLEDON [CUC]） proteins are one of the largest families of plant-specific transcription factors （Nagata et aL, 2015）. They are involved in many different biological processes including development and the response to biotic and abiotic stresses. To date, NAC transcription factors have only been identified in land plants （Zhu et al., 2012; Nagata et al., 2015）; and some of them control land-plant-specific processes, such as the formation of specialized water-conducting systems （Xu et al., 2014）. Therefore, it has been suggested that their appearance accompanied the emergence of land plants. Here, we exploited the transcriptomic data generated within the 1000 plants project （***, Wickett et al., 2014） to revisit the origin of NAC proteins. Our careful analysis shows that NAC transcription factors appeared before the ernergence of land plants as we detected their homologs in several groups of streptophyte green algae. The possible significance of this finding is discussed.

In the following paper we try to analyze the main characteristics of teaching ethics at university. In this particular case the student is an adult; we found several special features, for instance that the student has certain ideas and appreciations, certain moral intuitions which may interfere with the learning process. The idea is not just add more information and knowledge to the existing one, but to solve inconsistencies by restructuring prior knowledge. This is a transformation process that relies not only on cognitive aspects but also on sensitivity and action. Knowledge, sensitivity and action are different gateways to the complexity of ethical object at university classrooms. To perform this kind of experience you will need methodological strategies which involve integral education.

Texture analysis is important in several image segmentation and classification problems. Different image textures manifest themselves by dissimilarity in both the property values and the spatial interrelationships of their component texture primitives. We use this fact in a texture discrimination system. This paper focuses on how to apply texture operators based on co-occurrence matrix, texture filters and fractal dimension to the problem of object recognition and image segmentation.
