Igualdad y valores morales en la posmodernidad politica

The questions which have come up for discussion and the answers given under the concept of post-modern philosophy express continuity rather than rupture whith the philosophy of the modern era. If the philosophy of that age was characterized by its enlightened faith in autonomous Reason, both critical and transformative, that very power of Reason has now split up into a variety of rationalities endowed with the same characteristics as their progenitor. In spite of the general disillusionment of our times, new hopes and new projects of thought to give life a meaning are trying to make themselves heard, conscious as they may be of their limitations and relaliveness. Modern rationalism is still present in the political post-modern age as a kind of background stage setting which we refer to when we distinguish the reasonable from the absurd. Even for the expression of doubt we need a firm foundation of logical reason

Worldwide molecular epidemiology of HIV

O vírus da imunodeficiência humana (HIV), disseminado em todo o mundo, é o agente responsável pela síndrome da imunodeficiência adquirida (Aids). O HIV é um membro do gênero Lentivirus da família Retroviridae e compreende os tipos HIV-1 e HIV-2. Esses vírus possuem notável capacidade de mutar e se adaptar às novas condições do ambiente humano. Uma grande incidência de erros ao nível transcricional do genoma resulta em alterações nas bases genéticas durante o ciclo reprodutivo. A elevada variabilidade genômica do HIV apresenta importantes implicações para o diagnóstico, tratamento e prevenção, bem como nas investigações epidemiológicas. A elaboração desta revisão traz importantes conceitos sobre definições e distribuição geográfica de subtipos, formas recombinantes circulantes e outras variações genômicas do HIV. O estudo pretendeu direcionar os estudantes de ciências biomédicas e os profissionais de laboratórios de saúde pública aos conhecimentos gerais e específicos acerca da variabilidade genômica do HIV.Human immunodeficiency virus (HIV) is the worldwide disseminated causative agent of acquired immunodeficiency syndrome (AIDS). HIV is a member of the Lentivirus genus of Retroviridae family and is grouped in two types named HIV-1 and HIV-2. These viruses have a notable ability to mutate and adapt to the new conditions of human environment. A large incidence of errors at the transcriptional level results in changes on the genetic bases during the reproductive cycle. The elevated genomic variability of HIV has carried important implications for the diagnosis, treatment and prevention as well as epidemiologic investigations. The present review describes important definitions and geographical distribution of subtypes, circulating recombinant forms and other genomic variations of HIV. The present study aimed at leading students of Biomedical Sciences and public health laboratory staff guidance to general and specific knowledge about the genomic variability of the HIV

Democracy and national pluralism: Ethical and institutional features

The liberal, democratic and social rights included in constitutions are unable to regulate an egalitarian and equitable treatment of individuals belonging to national minorities. Moreover, it it impossible for states to play a culturally and nationally neutral role, the way they can regarding other phenomena, such as religion. Consequently, in many cases, national groups have an important moral role to play in not exhausting the individual components and dimensions of the basic values of liberty, pluralism and political equality.Original source: Revista de Catalunya, 298: 111-126 (2017

Advances in the study of nano-structured Co/MCM-41 materials : Surface and magnetic characterization

Co-modified mesoporous supports with MCM-41 structure and several metal loadings were successfully synthesized by a fast wet impregnation method. The nature and location of different Co species formed on the solids were inferred by TEM/SEM, XPS, XANES/EXAFS, adsorption of pyridine coupled to FT-IR spectroscopy and temperature dependence of magnetization. The presence of Co oxide species (clusters and Co3O4 nanoparticles) inside the channels of all the samples could be evidenced by TEM, XPS and XANES/EXAFS. In this sense, the surface Co/Si atomic ratios obtained by XPS were notably lower than the corresponding bulk Co/Si ratios obtained by ICP, indicating that the Co atoms are mostly incorporated inside the mesopores channels of the silica matrix. Nevertheless, by TEM, Co3O4 nanoparticles of small size segregated on the external surface of the silicate were also observed for the higher metal loadings. The temperature dependence of the magnetization performed for the Co/M(2.5) sample allowed to assign its superparamagnetic behavior to the presence of clusters and Co3O4 nanoparticles of very small size that grow inside the MCM-41 mesopores. Therefore, the analyses presented in this work indicate that a Co theoretical loading of 2.5 wt% leads to the formation of Co oxide nanospecies in the MCM-41 support with a particular superparamagnetic behavior. This sample with improved structural and magnetic properties result an attractive porous solid for drug hosting, to be applied in the field of the controlled release of medicaments.Instituto de Física La Plat

Rethinking Transnational Activism through Regional Perspectives: Reflections, Literatures and Cases

Copyright \ua9 The Author(s), 2024. Published by Cambridge University Press on behalf of the Royal Historical Society. This collectively authored article argues for a regional turn in the historical study of transnational activism. By considering not only pan-regional movements but also examples of borderland contexts, transregional connections and diasporic understandings of \u27region\u27, our discussion identifies fresh possibilities for investigating the evolution and functioning of transnational activism. Based on a Royal Historical Society-funded workshop held at and supported by Northumbria University, the article brings together insights from diverse locations and arenas of contestation. The first part considers literatures on three macro-regional settings - South Asia, Western Europe and Latin America - to illustrate the importance of distinctive regional contexts and constructs in shaping transnational activism and its goals. The second part turns to case studies of transnational activism in and beyond Eastern Europe, West Africa, the Caribbean and East Asia. In doing so, it explores very different notions of the regional to identify how transnational activism has both shaped and been shaped by these ideas. Taken together, the two parts highlight the role of regional identities and projects in challenging inequalities and external domination. Our analysis and examples indicate the possibilities of a regionally rooted approach for writing histories of transnational activism
