Over the past three decades, there has been an accelerated development of genetic technology, leading to its use in human genetic identification for many purposes. Additionally, it has been made explicit that identity is a fundamental human right. A number of historical circumstances have connected these developments. Personal identity is increasingly associated with the preservation and defense of human rights and is a tool to repair the violation of these rights, particularly the right to identity. In this article, we report the use of genetics to support the right to identity in two historical circumstances. First, we report the search, localization, DNA testing and genetic identification of 110 individuals who were appropriated as babies by the Argentine military dictatorship of 1976-1983 in the context of savage repression and egregious violations of human rights, including forced disappearance and suppression of identity. Second, we report on the repair of right-to-identity violations of hundreds of individuals that occurred during the process of compulsory isolation of patients with leprosy in Brazil through the Program "Reencontro", which has led to the genetic identification of 158 pairs of individuals who previously did not have proof that they were siblings. The high value placed on genetic identification by victims of identity suppression did not counter the prevailing view that genetic factors were not more important than other factors (social, emotional, educational, cultural, spiritual) in determining the complex phenomenon of personal identity. The use of genetic identification as a tool to redress and repair human rights violations is a novel application of human genetics for the benefit of mankind. © 2014, Sociedade Brasileira de Genética.

This paper reviews the health situation and developments in medical genetics and bioethics in Latin America, with a focus on Argentina. The region is the most inequitable in the world, with an average Gini Index of 52.5 and 25 % of the population living in poverty. Health expenditures are low and health systems are fragmented and privatised, with curtailed governmental responsibility and regulation. Health-care decision making is mostly in the hands of private insurance corporations and the medical-industrial complex, so that what is (or is not) covered by health plans is arbitrary and determined by the market and not by population health needs. This inequity and the lack of meaningful governmental intervention in the provision of health care, including genetic services, are at the heart of the bioethical dilemmas in Latin America. It is not surprising, therefore, that bioethics in the region has developed an approach grounded in social justice, equity and human rights as guiding principles, in contrast to the individualism espoused by Anglo-Saxon bioethics. The main ethical issues identified in genetics in Latin America are (1) inequity in access to genetic services, particularly in prenatal diagnosis, (2) genetic discrimination and (3) the lack of adherence to internationally accepted requisites of clinical validity and utility for diagnostic and predictive genetic testing. In this context, there is a risk that the impressive advances in genetics/genomics occurring in developed countries may fail to improve the public’s health and deepen inequity, with the implementation of expensive genetic technologies of unproven validity. © 2015, Springer-Verlag Berlin Heidelberg.

Human genetic identification has been increasingly associated with the preservation, defence and reparation of human rights, in particular the right to genetic identity. The Argentinian military dictatorship of 1976–1983 engaged in a savage repression and egregious violations of human rights, including forced disappearance, torture, assassination and appropriation of children of the disappeared with suppression of their identity. The ethical, legal and social nuances in the use of forensic genetics to support the right to identity in Argentina included issues such as the best interest of children being raised by criminals, the right to learn the truth of one’s origin and identity, rights of their biological families, the issue of voluntary versus compulsory testing of victims, as well as the duty of the state to investigate crimes against humanity, punish perpetrators and provide justice and reparation to the victims. In the 30 years following the return to democracy in 1984, the search, localization and DNA testing of disappeared children and young adults has led, so far, to the genetic identification of 116 persons who had been abducted as babies. The high value placed on DNA testing to identify victims of identity suppression did not conflict with the social consensus that personal identity is a complex and dynamic concept, attained by the interaction of genetics with historical, social, emotional, educational, cultural and other important environmental factors. The use of genetic identification as a tool to redress and repair human rights violations is a novel application of human genetics within a developing set of ethical and political circumstances. © 2015, Springer-Verlag Berlin Heidelberg.

José María ("Chema") Cantú (1938-2007), born in Mexico, was a pioneering, loved and respected leader in medical and human genetics and bioethics in Latin America. He graduated as a physician in Mexico and then trained in medical and human genetics in France and the United States. He was instrumental in developing a first-rate research, training and genetic services program in medical and human genetics in Guadalajara, in northwestern Mexico. He acted forcefully at national, regional and international levels to promote scientific development through collaboration and education in science and humanities, while he simultaneously strived for justice, peace, love and human rights. He attained some of the highest honors a scientist and humanist could aspire to as well as the recognition of the communities he served. Hundreds of disciples throughout Latin America and the world have been inspired by his vision of a better world through the conjunction of science, respect for humankind, ethics and love. © 2014, Sociedade Brasileira de Genética.

The particle-particle method for N-Body problems is one of the most commonly used methods in computer driven physics simulation. These algorithms are, in general, very simple to design and code, and highly parallelizable. In this article, we present the most important approaches for the application of the three performance improvement areas on these algorithms when executed on high performance computing (HPC) clusters: 1) sequential optimization (a single core in a node of the cluster), 2) shared memory parallelism (in a single node with multiple CPUs available, just like a multiprocessor), and 3) distributed memory parallelism (in the whole cluster). For each one of the improvement areas we present the employed techniques and the obtained performance gain. Also, we will show how some (sequential/classical) code optimizations are almost essential for obtaining at least acceptable parallel performance and scalability.

This article contends that for socialist emancipation to advance it is crucial to investigate how political cadres conceal, regulate or displace the demands of citizens and workers in the context of the calamitous effects of global capitalism. Analyzing the constitutive relationship between politics and the media is an essential component in researching those practices of state ideological production. Specifically looking into the transformation of media policy in the case of Argentina, this article problematizes the different political forms through which the state has cloaked its fundamental contradiction: alleged representation of the general interests of citizens, when explored in critical depth, reveals the state's actual adjustment to a process of capitalist transnationalization that increases irrationality, social inequality and misery. Through this lens, the article emphasizes the value of Marxist dialectic method and theory in imagining a true democratic future.

Relational machines (RM) were introduced as abstract machines that compute queries to relational database instances (dbi’s), that are generic (i.e., that preserve isomorphisms). As RM’s cannot discern between tuples that are equivalent in first order logic with k variables, Relational Complexity was introduced as a complexity theory where the input dbi to a query is measured as its sizek, i.e., as the number of classes in the equivalence relation of equality of FOk types of k-tuples in the dbi. We describe the basic notions of Relational Complexity, and survey known characterizations of some of its main classes through different fixed point logics and through fragments of second and third order logics. © Springer International Publishing Switzerland 2016.

Current MDD methodologies are complex to use and require doing lots of models and configurations. Usually after all that effort only some part of the application source code can be automatically created. It would be desirable to have a more simple technique, but powerful enough for automatically creating a fully functional application. This works introduces a component based model driven development approach where a set of user interface components will be configured to define system behavior. Component configuration will be direct, simple and supported by a modeling tool which also includes automatic transformations for reducing the modeling task. The methodology requires the designer to build only two models: a class diagram, representing the data model of the application and a component diagram defining the user interface and the system navigation. Both components are based on UML extended with stereotypes and tagged values allowing configuring the system behavior. Copyright © 2015, IGI Global.

Objective: Deterioration of healthy habits in young people, particularly undergraduates, justifies their study in these populations. The aim of the present research is to analyze physical activity levels of students from the Universidad Nacional de La Matanza (Argentina), trying to describe homogeneous groups by demographic characteristics, health habits and perceived wellbeing, and to identify the level of physical activity that best describes each of the groups.Methodology: Participants were 554 students (281 males and 273 females) of different careers which were applied the Global Physical Activity Questionnaire (GPAQ), and a survey related to health habits, perception of happiness and other demographic variables. Measures of central tendency and variability, and percentiles P25 and P75, were calculated for all variables. Segmentation was performed using hierarchical cluster analysis, after a previous factor analysis.Results: 79.8% of students, and 97.2% of Physical Education students met the recommendations of physical activity. Students identified with a high physical activity level were those who attended in day shift, did not smoke, did not consume alcohol or drugs, did not work, had no children or stable partner, and with a medium socio-economic level.Conclusions: It is suggested the need for a strong educational intervention by universities to promote healthy habits and regular performance of physical activity, as they have a primary social responsibility regarding these issues. © 2014, Grupo Aula Medica S.A.

Argentina is a middle-income country with a population of 40 million people. The structure of morbidity and mortality approaches that of more developed nations, with congenital and genetic disorders contributing significantly to ill health. The health delivery system is mixed, with public, social security, and private sectors which together spend close to 10 % of the GNP. Health subsectors are decentralized at provincial and municipality levels, where health planning and financing occurs, leading to fragmentation, inefficiency, and inequities. There are about 41 clinical genetic units in major medical centers in large cities, staffed by about 120 clinical geneticists, although only a few units are fully comprehensive genetic centers. Duplications, deficiencies, and poor regionalization and coordination affect health care delivery in general and in genetics. Funding for genetic services is limited due to poor understanding and lack of political will on the part of health authorities. Recently, however, there have been some interesting initiatives by national and provincial ministries of health to improve genetic services delivery by increasing coordination and regionalization. At the same time, training in genetics of health professionals is occurring, particularly in primary health care, and registries of congenital defects are being put in place. These developments are occurring in conjunction with a new awareness by health authorities of the importance of genetics in health care and research, a heightened activism of patient organizations demanding services for neglected conditions, as well as of women movements for the right to safe abortion. © Springer-Verlag 2012.
