Even though a large majority of young people consider gender-based violence as a serious social problem, in recent years opinions are increasing that tend to deny or limit the importance of genderbased violence in youth relationships. This research try to discover if the content of urban music songs that are currently extraordinarily successful among young audiences have a responsibility in the normalization of gender violence. To do this, analysed the use and consumption that young Spaniards make of Reggaeton and Trap songs based on a survey of 1000 individuals of both sexes, aged between 15 and 25 years. The intersection of sociodemographic, cultural and educational variables with the characteristics of urban music consumption, the theme of the songs and the form of exhibition lead us to conclude that Reggaeton and Trap songs, based on continuous novelty and violent and sexist lyrics, are one of the most powerful influences when it comes to transmitting values to young people who are very attracted to these sounds in a stage of personal development where they question the values transmitted by the family and the educational system.

In our society the numbers of sexist aggressions increase among teenagers. This research proposes an analysis of the adolescents' musical discourse that establishes a relationship between the presence of sexist content in these cultural contents and the normalization of these behaviors in their social interaction patterns. First, the work proposes a quantitative methodology based on the content analysis of a sample of 350 songs whose lyrics are related to gender violence. The results show that although the messages against gender violence are more common in the songs analyzed, the contents that promote gender violence are the most distributed by the cultural industries and, therefore, the most successful among teenagers. Secondly, the paper proposes a work methodology that uses the educational power of music to socialize adolescents in values that help them identify and combat gender violence. [ABSTRACT FROM AUTHOR]

Popular music offers an exceptional opportunity to connect with reality and reflect on its problems. The objective of this work is to study how gender violence is treated in songs in Spain, relating musical styles with the description of the cycle of violence. We use a quantitative methodology based on the content analysis of a sample of 210 songs with this theme accumulated over the last four decades. The results show that as society internalizes the seriousness of the problem, gender violence becomes a constant in the discourse of popular music. [ABSTRACT FROM AUTHOR]

Software testing can exceed 50% of the total cost of a software project, which is why companies need an alternative to reduce their cost and time of implementation. This research proposes the use of combinatorial structures known as Covering Arrays (CA) and Mixed Covering Arrays (MCA), which guarantee the detection up to 100% of errors with a minimum amount of testing. With this approach, a Visual Studio.NET add-on was developed for the optimization of the tests and its use was evaluated with students of last academic term of Computer Science Engineering and of a software company. The results obtained are promising and motivate the research group to disseminate its work at the national level. The research project was funded by the Vice-Principal Office of Research of the Universidad del Cauca. [ABSTRACT FROM AUTHOR]

Violence against women remains a first-order social problem in contemporary societies. The objective of this work is to study how this problem is treated in popular music songs in Spain, establishing a relationship between the different musical styles and the description they make of gender violence. This research is developed from a quantitative methodology based on the content analysis of a sample of 210 songs that deal with gender violence in their lyrics over the last 40 years. This research wants to show how popular music songs are an ideal communication tool to raise awareness of the dimensions of the problem of gender violence. [ABSTRACT FROM AUTHOR]

project is described with the objective of making a division into subsectors of the drinking water network of MHO-31 sector of Miguel Hidalgo delegation in Mexico city, in order to make a better delivery, distribution and control of water discharge, by using, among other accessories, the installation of pass valves and pressure regulation valves. EPANET software was used to perform its hydraulic analysis. The network model calibration was made with respect to water loss and water discharge, taking into account measured data and the emitter coefficient. The network was modeled for its design alternative, with the pressures regulation valves open and later with this valves in operation. This allowed a recovery of a water volume of 14262 m³ per day, so the water fligths were reduced in a significant way. [ABSTRACT FROM AUTHOR]

This article describes and analyzes the transmedia experience of the research project "Simulator IC, a transmedial test scenario for the simulation of collective intelligence", in which the ability of four fictional artifacts was explored, --literary text, comic, videogame and role-playing game-- generated from the transmediation of a literary source to develop sensitivity in resolving problems with characteristics linked to collective intelligence. The research method was mixed, with a main qualitative component and a quantitative one --observational methodology--. When a measurement of the collective intelligence gradient of the participants was performed upon contact and interaction with various problem simulation strategies --artifact combination according to a specific experimental design--, it was found that the complete transmedia experience, ie. Interaction with the four artifacts, enhances the effects and benefits the simulation with individual artifacts. It is also concluded that the participants who interacted with various artifacts combinations offered alternatives of collaborative solutions to everyday problems. [ABSTRACT FROM AUTHOR]

Rubble mound breakwaters are structures providing adequate to harbour infrastructure, so it is essential to have an appropriate knowledge of its behavior under wave action. Wave action generates several hydrodynamical effects on the breakwater, of which reflection is the object of this work. This work was realized in the "Laboratorio de Ingeniería Hidráulica de la Escuela Superior de Ingeniería y Arquitectura, del Instituto Politécnico Nacional de México", in a narrow channel with hydraulic generator of irregular waves and wave meter equipment controlled by computer. Given the above, it was possible to analyze the behavior of the incident waves group over the structures through wave reflection measurements, photographs and video, which represented information that was compared with results.

Our behavior is determined by the characteristics of the culture in which we live. Culture imposes on us ways of thinking and perceiving, habits, customs and usages. Music is a form of cultural expression that has a very important role in the social construction of reality. Music has always accompanied man, is one of the oldest rituals of human kind. No one knows exactly how and why the man has started to make music but the music has been a means of perceiving the world, a powerful instrument of knowledge. Traditionally, creation and distribution of music has been tied to the need to communicate feelings and experiences that can not be expressed through common language. This paper describes how our society has generated a multitude of sounds that are distributed freely through the new technologies. This set of sounds is creating cultural identities that are unable to manage his current music and understand their communicative speech. To this end, the paper examines the profound changes that music is experiencing in a consumer society. These changes make it necessary to establish a new paradigm for analysis that allows structuring the diversity of sounds, analyzing their creation, distribution and consumption. Finally, the paper states that permanent contact with the music changes the way we perceive sounds. In contemporary society, music has gone from being a vital need to become an instrument of consumption. This has led to significant changes in their functions, significance and social use.

This article intends to review the state of contemporary narrative, departing from a literary perspective and advancing toward its role and use in social sciences. After an initial distinction of the terms narration, narrative and narratology, the itinerary that goes from modern novel to digital narrative is showed, going through postmoderm novel and testimony writing. This first part ends by outlining the distinction between text-as-world and text-as-game. Then a reflection about the hybrid literary forms is proposed, to advance into the description of five mass media narratives: journalism, advertising, radio, television, and video. Then, the topics of eccentric narrations and dialogic criticism are developed. The last part is dedicated to describe the uses of narration in fields other than literature, like history, postmodern anthropology, "ethotext" and "oral literature", nation studies and therapy.

The emergence of interactive digital technologies has begun to affect discursive practices as solid as literature or creative writing. On the one hand, the circulation of commentary of literary works has become massive and even the license of the reader to intervene such texts is now open; on the other hand, the expression modes and base has been enhanced thanks to the creative use of recombination technologies, even if this means that the resulting products cannot be labeled as literary works and should therefore be placed within the realm of that emerging field where works based on digital interactive technology are now being assigned to, the so called net-art. Furthermore, the numbers of producers is also widening, that is, more and more people have the skills to generate new work (even if they are "small works"); and, finally, the modes of production of such works are also widening to include works that manage singularities as well as collaborative and collective work. This article reflects on possible scenarios for such transformations. [ABSTRACT FROM AUTHOR]

There's no doubt hypertext has been an outstanding event in the cyber culture. It was by itself a very singular happening since it re-configured the conceptions of writing and reading and also allowed sharing the knowledge because it increased the interactivity and the freedom among readers and writers. However these characteristics of the hypertext have been surpassed with the increasing numbers of new tools and scenarios for the communication thru internet. In first place it comes the so called hypermedia or platforms where the structure is basically non- lineal and with an interactive design so everything goes beyond words, including images, audio, video, animations creating a whole new concept. But it is till the creation of the web 2.0 when all the educative and communicative potential of this we-based information reaches a great height. In this article we will discuss the emergence of these new technologies (blogs, wikis, portfolios) and which are the main challenges for teaching and learning. [ABSTRACT FROM AUTHOR]

Using a biocathode microbial fuel cell formed by graphite electrodes submerged in the anodic and cathodic chambers separated by a salt bridge, it was possible to reduce hexavalent chromium, degrade organic matter and generate electricity. Sulfidogenic sludge or Pasto river water contaminated with industrial waste from tanneries was employed as source of microorganisms for the cathode. The best experimental condition for simultaneously removing organic matter and chromium occurs during the first cycle of operation of the cell, using Pasto river water contaminated as inoculum and the lowest glucose concentration (0.05 M), achieving 97.9% of organic matter removal, 86.3% of chromium and a coulombic efficiency of 0.92%. This study represents a contribution for improving the performance of a biocathode cell and it provides the tools for bioremediation processes in systems contaminated with chromium and organic matter.

The most important issues that affect the performance of a microbial fuel cell, such as its architecture, microbial function and the type of substrates are presented and discussed. In the last decade these bio-electrochemical systems have attracted the interest of many researchers, not only because of the global trend towards sustainable energy production, but also due to their simultaneous operation to degrade organic matter and bioremediation. These applications depend essentially on microbial metabolism whose knowledge is still limited, being necessary a better understanding of the complex microbial ecology. In developing countries it is important to investigate others sources of microorganisms and substrates with varied chemical composition which might be potential fuels in cells of different configuration. More intense research of these aspects will be essential to optimize and improve these processes. [ABSTRACT FROM AUTHOR]

In the Mexican economy, and especially in the Soconusco region of Chiapas, coffee is economically important, and sustainable management most cover pests and diseases. In this study, we searched for native arbuscular mycorrhizal fungi (AMF) that could be used as biofertilizers in coffee cultivation. We collected 21 soil samples from seven coffee plantations (Coffea canephora) in November 2015. We used wet sieving and decanting to quantify abundance, richness and composition of morphospecies, as well as their relationships with soil properties. A total of 20 morphospecies and five new records of AMF were obtained, and the most frequent genera were Acaulospora and Glomus. The Toluca and Victoria sites had more morphospecies richness (17 spp. each) than San Agustín, November 20 and San Luis Nexapa (4-7 spp. each). Providencia and Platanar were intermediate but had the highest spore abundance. The dissimilarity of Victoria and Toluca may reflect a low concentration of PO4 -3 in the soil. P availability, linked to soil acidity, sems to be regulating these mycorrhizae communities at Soconusco. AMF consortia specific for soil P-levels and acidity, i.e. Acaulospora and Glomus consortia, may occur and be common in the environmental conditions of Mexican coffee plantations, Strains should be tested for compatibility and functionality before using them as native biofertilizers.

The objective of the study presented in this paper was evaluating the educational software Agroforestry World (Mundo Agroforestal) by rural young men and women from the educational institution Francisco de la Villota in Nariño, Colombia. Information and Communication Technologies are widely used for facilitating educational processes. The relatively new educational software Agroforestry World has not been assessed regarding the learning outcomes that might result from its application. Analyses were done through a TStudent test and a general linear model. After some time, significant learning processes in agroforestry were obtained. It was observed that the use of the software facilitated students' comprehension of the different topics, improving self-learning. [ABSTRACT FROM AUTHOR]

Although the State of Veracruz is a megadiverse entity, it has the highest annual deforestation rates. Protected natural areas are considered strategic to preserve local biodiversity. In this paper, composition and alpha diversity of ant assemblages were analyzed in the natural protected area 'Metlac' near Fortin, Veracruz, Mexico. Sampling was conducted at four transects using baited pitfall traps and hand-collection. In total 3,204 ant workers belonging to 36 species, 21 genera, 12 tribes, and seven subfamilies were collected. The average alpha diversity was 16 species and no significant differences between recorded richness in each transect were found. Average sampling completeness was above 80%. Locally, Solenopsis geminata and Nylanderia steinheili dominate the epigeous and shrub strata due probably to their biological, behavioral and ecological plasticity that allows them to easily adapt to disturbed environments. This paper shows that for the small area sampled, the relict of tropical semi-evergreen forest is of great biological value despite heavy human intervention and the space-geographic context in which it is found.

Currently there is an increase in tropical crops dedicated to ornamental horticulture. This study is the first assessment of the role of a Heliconia spp. ornamental plant cultivation in Mexico as habitat for insect biodiversity conservation, using ant assemblages as bioindicators. A total of 9,022 ant workers belonging to seven subfamilies, 14 tribes, 27 genera, and 55 species was captured. Conversion of native vegetation to tropical ornamental agriculture affects the richness, diversity and dominance of ants, but not assemblages' composition. The importance of species composition as a predictor parameter of functional changes in the landscape is highlighted. [ABSTRACT FROM AUTHOR]

A study was conducted to evaluate the effect of brassinosteroids (CIDEF-4) on maize hybrids with male sterility and normal fertility. Ten genotypes and two doses of brassinosteroids were evaluated (30 y 60 g/ha), a control treatment was included without brassinosteroid application. A randomized block design with four replications was used. There was not a significant difference in yield when brassinosteroid CIDEF-4 was applied to the ten genotypes. However, when the ten genotypes were classified according to hybrids types, the three-line hybrids with male fertility and brassinosteroid (CIDEF-4) were statistically different. The yield with 30 g/ha of CIDEF-4 was 8,083 t/ha, while the check without brassinosteroid yielded 3,858 t/ha. The three-way androsterile hybrids did not show significant statistical differences for the evaluated variables. In contrast, in the single-cross hybrids with male sterility and normal fertility, the application of brassinosteroids caused earlier male and female flowering. [ABSTRACT FROM AUTHOR]
