Abstract: this descriptive study with a qualitative approach is aimed to try to understand the meanings that mexican women attribute to alcohol consumption. the methodological reference framework was the case study, from the theoretical perspective of symbolic interactionism. ten women participated in this study. data was recollected through semi-structured interviews. the interviews were recorded, transcribed, coded and categorized, based on the analysis of the content analysis. the study revealed that alcohol makes the women become another person the one they really wanted to be> this is mainly the reason why they continued drinking on a regular basis, at increasing levels. in the context of symbolic interactionism, we observed that these women's self was restricted by the daily demands, consolidating a self that responds more to the sociocultural expectatives (me) than to their own (i) expectations. they discovered that alcohol stimulated the expression of their selves , unleashing another person inside them, which normally does not manifest itself

Abstract: El propósito de este estudio fue conocer de qué manera afectan los factores personales biológicos, socioculturales y el afecto, el consumo de alcohol en los trabajadores de una industria petroquímica del sur de Veracruz, México. La muestra fue de 219 trabajadores, se aplicaron 2 cuestionarios: uno de Afecto Relacionado al Consumo de Alcohol y el AUDIT. Los resultados mostraron que los hombres consumen más que las mujeres (U=1042.50, p<.01), los trabajadores administrativos consumen más que los obreros (U=4333.50, p<.01). El sexo, la escolaridad y el ingreso económico tuvieron efecto significativo sobre el consumo de alcohol (F(3,215)=10.56, p<.01). El afecto negativo se asoció significativamente con el consumo da ino (rs=.22 p<.02) y mostró variación significativa antes, durante y después del consumo (p<.01).

Abstract: the study aims to identify patterns of alcohol consumption in mexican medical students. this is a cross-sectional study, conducted at the university of veracruz, mexico. the sample comprised 263 students (84.4%). the alcohol use disorders identification test and the student questionnaire 2006 were used. students were characterized by youth and women. seventy-two percent used alcohol in the lifetime, with 12.5 years as the onset age. the frequency of consumption was low but the quantity high, with a pattern of drunkenness, mainly among men. forty-six percent consumed beverage at a problematic level. students perceive that parents and teachers badly assess alcoholic beverage consumption. this study contributes to the planning of preventive programs for alcohol consumption, to be applied in the university context.
Socio-Spatial Inequality and Violence  [PDF]
Cecilia Hita Alonso, Leticia Sánchez Hita
Sociology Mind (SM) , 2013, DOI: 10.4236/sm.2013.34040

Since the 70s, neo-liberalism has lead to increased social segregation and the segmentation of land according to a population’s social-economic status and the transformation of the labour market. That is to say, we are experiencing a process of social-spatial segregation which can be defined as the agglomeration of families with the same social condition in separate spaces. Segregation can depend on ethnicity, migration background or socio-economic situation, among other conditions and it impairs the mechanisms of social cohesion as it generates social differentiation which in turn breeds tension and fear. This mechanism is leading to the appearance of new areas such as gated communities, gentrification, hyper-degraded areas etc., which are as much a result of the heavy spatial concentration of the elite as of the agglomeration of the poor. This continues to happen, even with the knowledge that in the long-term, a non-segregated, inclusive space is one of several necessary measures in reducing violence and other dangerous behaviours, in the same way as a developed economy which fosters a stable and balanced job market. This article analyses the mechanisms which produce these processes.

Comprehensive Study of Honey with Protected Denomination of Origin and Contribution to the Enhancement of Legal Specifications

Molecules , 2012, DOI: 10.3390/molecules17078561
Abstract: In this study the characterization of a total of 60 honey samples with Protected Denomination of Origin (PDO) collected over three harvests (2009–2011, inclusive), from the Northeast of Portugal was carried out based on the presence of pollen, physicochemical and microbiological characteristics. All samples were found to meet the European Legislation, but some didn’t meet the requirements of the PDO specifications. Concerning the floral origin of honey, our results showed the prevalence of rosemary (Lavandula pedunculata) pollen. The microbiological quality of all the analyzed samples was satisfactory, since fecal coliforms, sulfite-reducing clostridia and Salmonella were absent, and molds and yeasts were detected in low counts. Significant differences between the results were studied using one-way analysis of variance (ANOVA), followed by Tukey’s HSD test. The samples were submitted to discriminant function analysis, in order to determine which variables differentiate between two or more naturally occurring groups (Forward Stepwise Analysis). The variables selected were in this order: diastase activity, pH, reducing sugars, free acidity and HMF. The pollen spectrum has perfect discriminatory power. This is the first study in which a honey with PDO was tested, in order to assess its compliance with the PDO book of specifications.
Cuerpos en contraste: reflexiones sobre el tratamiento de los difuntos en dos entierros de 3.000 a os A.P. (Valle del Cajón, Noroeste argentino)
Leticia Inés Cortés
Revista del Museo de Antropologia , 2010,
Abstract: Two funerary contexts dated to 3.000 years B.P. from the southern Cajón Valley showed interesting contrasts as far as the treatment, disposition and association of the bodies with diverse objects is concerned. The first one is a multiple internment where several bodies were laid out mixed with one another without any anatomical articulation. These were associated to an anthropomorphic copper mask. The second one is the inhumation of a child in an extended position associated to a lithic bead and a copper pendant. Both contexts were set adjacent to each other though separated by symmetrical and opposed stone structures.Along with some perspectives suggested by the anthropology of the body and studies of materiality, I explore a first interpretation in which bodies are considered the axis of the analysis. The way bodies were treated –the obliteration or conservation of their anatomy, their association with objects that could refer to a human collective in contrast to those of personal use and demarcation, as well as the inverse disposition of the structures that contained them, allows to think that notions of symmetry and opposition would have been implied in the treatment of the deceased by those who inhabited the valley three thousand years ago.
Proceso de formación del investigador en el área tecnológica: El caso de los programas de Postgrado del CENIDET
Sánchez Lima, Leticia;
Revista de la educación superior , 2008,
Abstract: the formation process of researchers in the field of engineering is analysed in this document. it is described from a psycho-pedagogical perspective, based on a study case within a research and technological development center in méxico. it is supported by a qualitative research methodology, that is, interviews, observations and school mark histories. there for, formation paths of different master degree students were recovered. based on the historic-cultural theory developed by the soviet psychology and, the formation theory of bernard honoré, therefore, a theoretical apparatus was built from which the analysis categories were derived. in its turn, the knowledge of reality offered new elements to support these categories to, finally, build an original explanation to the matter.
Profesores frente a los videojuegos como recurso didáctico

Didáctica, Innovación y Multimedia : DIM , 2013,
Abstract: The present experience narrates how a group of teachers of different educational levels, incorporate the video games as didactic resource in the classroom, with the aim of: to identify how the learning develops in a gradual way for discovery, experiencial and autorregulado. The results show that the video games are a technology that forms a part of the daily life of the pupils and his incorporation inside the classroom allows to approach different matters and to develop a series of skills and skills.The most significant of the results of this work sustained in the Investigation-action and that does not form a part of the central aim, is to see how throughout twenty weeks of work, who modify in a substantial way his attitude opposite to the video games they are the teachers, who had never taken advantage of them as didactic resources, they were labeling them as games of leisure and even they were not accustomed to play them. Across the forums that were enabled to discuss his advances, they expose the challenge that meant to select the video games of agreement to the topic, to include them in his planation, narrate his impotence for not possessing the infrastructure in his schools and ultimately they accept that really they are a potential resource.

Didáctica, Innovación y Multimedia : DIM , 2013,
Abstract: They summarize: In this communication, is explained the work that is developing, in using the bidimensionalidad as way of communication in the electronic forums, with the aim to promote and strengthen the critical reading of the participants of postdegree of the Latin-American Institute of the Educational Communication (ILCE). Concretely, one presents the use of code QR as strategy to share the summaries of the requested texts, besides the reflections and feedback between them, in only 140 characters.The article is organized in four general paragraphs. First, one presents the State of Art of the object of study, in which, from a bibliographical review, there is defined the concept of critical reading and the use of code QR as a didactic resource. In the second paragraph explains the experience realized with pupils of the module of Education distantly, sustained in the beginning that Paul and Elder (2003) who propose for the development of the critical thought eight steps. The third party mentions the methodology and procedure for the compilation of information. In the quarter, one presents development of the experience and finally, there are exposed the conclusions extracted from the analysis of the information, where there is verified the importance of the use of codes QR for the development of the critical reading. Is outlined the process of chaos, uncertainty and acceptance through that there lived the pupils, who had never used this resource and even they had never translated a code.
Inhibitory Effect on In Vitro Streptococcus oralis Biofilm of a Soda-Lime Glass Containing Silver Nanoparticles Coating on Titanium Alloy

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0042393
Abstract: This paper reports the effect of soda-lime-glass-nAg coating on the viability of an in vitro biofilm of Streptococcus oralis. Three strains (ATCC 35037 and two clinical isolates from periodontitis patients) were grown on coated with glass, glass containing silver nanoparticles, and uncoated titanium alloy disks. Two different methods were used to quantify biofilm formation abilities: crystal violet staining and determination of viable counts. The influence of the surface morphology on the cell attachment was studied. The surface morphology was characterized by scanning electron microscopy (SEM) and using a profilometer. SEM was also used to study the formation and the development of biofilm on the coated and uncoated disks. At least a >99.7% inocula reduction of biofilm respect to titanium disks and also to glass coated disks was observed in the glass-nAg coated disks for all the studied strains. A quantitative evaluation of the release of silver was conducted in vitro to test whether and to what extend the biocidal agent (silver) could leach from the coating. These findings suggest that the biofilm formation of S. oralis strains is highly inhibited by the glass-nAg and may be useful for materials which require durable antibacterial effect on their surfaces, as it is the case of dental implants.
