Reflections on how scientific knowledge and chemical development has been formulated and constructed, have led to an in-depth review and analysis about the nature of the theories, laws, models and concepts, which can be termed as the "conceptual structure of chemistry." This work focuses on the review and analysis of both the dual theory of J. J. Berzelius theory, as well as the unitary one by A. L. Laurent, as potential structural axes of Organic Chemistry. In this sense, we try to reveal the confrontation of positions of empirical scientific communities representative of nineteenth century. The unitary theory - or antidualistic - has consolidated today as theory, to achieve assertive explaining of chemical phenomena, which has been not possible with the dual theory. Such revision of the two structural theories was made from an analytical perspective, which included the theoretical assumptions of Thomas Kuhn on the development of scientific knowledge. This account of scientific conceptions and preconceptions own of its time, on the "effective" matter composition, with an approach to different concepts of "weight" in the construction of such theories, which will hopefully reflect the historical-epistemological discussion on the chemical nature of scientific knowledge. © Universidad Nacional Autónoma de México.

Aims: Until now, the success of improved cook stoves (ICS) implementation programs has usually been measured by the number of ICS distributed. Some important research has been conducted to try to determine the effects of the use of an ICS in the user's health, but these studies are expensive and time consuming. Moreover, no evaluations show the impact of the technology in the user's lives. This study seeks to contribute to fill this gap. Scope: By applying cluster analysis techniques to survey data, the most relevant variables that explain adoption and impact were identified. Using these variables, two qualitative indexes are proposed: The adoption index considers the use of the new technology, the level of satisfaction, and the conditions of the stove. The impact index considers the changes in cooking practices and life quality brought about by the ICS. Both indexes are then applied to two implementation programs. The indexes show the differences between the program results and the user's perceptions of each technology. Conclusions: The proposed indexes can be used to measure the success of an ICS implementation program in terms of the benefits perceived by the users of these technologies. © 2013 Elsevier Ltd.

Objective: To investigate the relationships between menarcheal timing and both menarcheal experience and attitudes toward menstruation in Mexican girls. Design: Cross-sectional survey. Settings: Sample of adolescents attending 10 different public schools. Participants: Mexican postmenarcheal adolescents, aged 11-16 years. Intervention: Participants answered 1 questionnaire about menarcheal experience and another about attitudes towards menstruation. Results: Early maturers (menarche before 11 years) were more likely than average (menarche at 11 or 12 years) or late maturers (menarche at 13 or more years) to state they had not known what they should do at the moment they got their first period (P < .01), that they had not felt prepared to start menstruating (P < .05), and that they thought they must keep secret the fact of already having had their first period(P < .05). Concerning their emotional reactions to menarche, early maturers were the most likely to have felt scared (P < .05), worried (P < .05) and sad (P < .05) and were the least likely to have felt calm (P < .05). They were also the most likely to show current secretive attitudes towards menstruation (P < .01). Finally, late maturers showed more positive attitudes toward menstruation than their peers (P < .01). Conclusions: These results could be useful for developing resources to help early maturing girls manage menstruation. Since these girls have limited or in some cases no time for preparation, they need special support. © 2014 North American Society for Pediatric and Adolescent Gynecology.

This paper aims to reflect the experience of the Department of Sociology of Education at Pedagogical University of Mexico with a project based on the use of the Moodle learning management system. Moodle is selected a flexible environment that minimizes time and space barriers and increases communicative options by offering new alternatives for tutoring and assessment. We analyze the results obtained so far and formulate some recommendations in order to improve future use of the platform.

This paper presents an overview of what is understood by inquiry. We started with a brief historical introduction and then a short review of what is found in literature of what inquiry is. Next, we presented some teaching-learning strategies based on inquiry that have been developed and worked. Finally, it is shown where and who is doing inquiry in Mexico. © Universidad Nacional Autónoma de México.

Same-sex sexual practices among men in Mexico City are stigmatized. This article analyzes sexual practices and experiences of gay men in Mexico City and its implications on emotional and sexual health. The concept of sexual practices is used from a public health perspective, and the concept of sexual experiences from a psychological one, intending to understand both physical and emotional discomfort and pleasure in sexual contexts. The aim of this article is to analyze sexual practices and experiences of gay men in Mexico City and its implications on health, particularly emotions that can lead to depression, anxiety, substance abuse, and unsafe sex. Fifteen in-depth interviews were carried out with gay men of three generations who live in Mexico City. The data were analyzed using techniques from grounded theory to identify categories, and critical discourse analysis as an analytical approach to understand how social discourses affect subjectivity, emotions, and practices. Sexual practices and experiences are the result of homoerotic desire, which gender and heteronormative culture encourage to be kept hidden and clandestine. This leads men into risk contexts where practices are hardly negotiated, thus exposing themselves to sexually transmitted infections and abuse. These practices also produce a series of emotions such as guilt, shame, fear, and sadness that may develop into mental health issues such as depression and anxiety. Interventions at all levels must consider homophobic discrimination as part of gay men’s daily lives and should be oriented toward decreasing it, to diminish discomforting emotions and reduce the probability of unsafe sex practices. © 2014, © The Author(s) 2014.

A number of findings from research in science education are well known and broadly accepted. They refer e.g. to inquiry based, learning by doing, social dimension of learning, active learning, diversity of learning styles, based on individual, cultural, ethnic, gender-related factors. For researchers working side by side with school teachers, it is everyday experience to see how difficult it is to receive indications coming from research and transform them into teaching practice: there are cultural barriers, preparation barriers, time and resource constraints. TRACES will promote transformative research activities and investigate the factors that contribute to the research-practice gap and identify innovative policies in science education that can contribute to fill that gap. It will do so through both desk and field research, in a cyclic process of analysis, action, reflection. In particular, we are interested in looking at the effectiveness of research based science teaching in taking account of learners diversities in terms on individual, cultural, ethnic, linguistic, gender-related factors.

Violence against women is a social and public health issue in Mexico. The aim of this article is to explore violence among an understudied group of women, who attended Mutual-Aid Residential Centers for Addiction Treatment and experienced stigma both as women and addicts. These centers are particular kind of addiction treatment services that stem from 12-step philosophy, but that have been found to manipulate said philosophy and exercise extreme forms of psychological and physical violence.Thirteen semi-structured interviews were carried in 2014 and 2015 out with women who resided in at least one of these centers to understand their experiences of violence prior and during their rehabilitation process. The interview guide covered questions regarding substance use initiations, family violence and dynamics, and rehabilitation experiences. Qualitative data was analyzed using interpretative-phenomenological analysis.Two categories emerged: violence and substance use and abuse, and violence against women in recovery. Results show that all participants experienced violence in their family since childhood, particularly sexual and physical violence. As a result, participants experienced guilt, sadness and shame, which led them to contexts of consumption. Violence continued as they explored alcohol and drug use, even though women felt empowered.Treatment reproduced masculine violence constantly, but women felt that they were in a context that helped them understand their addiction. Even though women felt these centers played a crucial role in their recovery, womens particular needs and experiences are not considered in the treatment program.

This article resurrects the puppet show Las calenturas de Don Ferruco (Don Ferrucos Fevers), which was televised in the late 1950s in order to help eradicate malaria in Mexico, as a useful instrument for health education. It analyzes how the spread of educational puppet shows on Mexican television showed the need to keep updating preventive healthcare pedagogy and it underlines the importance of television as an educational health-promotion production in the mid-twentieth century. The article discusses the early use of puppet shows as an especially important tool for what would later become mass-media transmission of discourses from the Secretara de Salubridad y Asistencia (Department of Health and Healthcare).
