Informa??o e trabalho no capitalismo contemporaneo
Dantas, Marcos;
Lua Nova: Revista de Cultura e Política , 2003, DOI: 10.1590/S0102-64452003000300002
Abstract: this articles presents a marxian-inspired explanation for the current changes in our society, founded on the understanding of the productive and value-based role of information and knowledge in all evolutive stages of the industrial capitalism. it reviews some key properties of the capital-labor relations displayed along the previous industrial revolutions, showing how new productive relations and new top industries came up from them, supported on information and culture, through which the accumulation of capital, as well as the new social dramas, get their way. the private appropriation of information is seen as the major economic, social and political problem to be tackled with in the beginning of this century.
Os significados do trabalho: produ??o de valores como produ??o semiótica no capitalismo informacional
Dantas, Marcos;
Trabalho, Educa??o e Saúde , 2007, DOI: 10.1590/S1981-77462007000100002
Abstract: in advanced capitalism, in all industries the labour process has become essentially semiotic, that is, in all steps of the productive chain, from engineering to machine adjustment and control, workers are employed to process information to which they can attribute meanings related to concrete labour situations. understanding this process helps to understand the marxian concept of concrete labour and can contribute to a better understanding of the nature of the informational capitalism that has been emerging in the beginning of this century.
Informa o e trabalho no capitalismo contemporaneo
Dantas Marcos
Lua Nova: Revista de Cultura e Política , 2003,
Abstract: Este artigo prop e uma chave explicativa, de fundamento marxiano, para as transforma es em curso na sociedade, com base na compreens o do papel produtivo e valorativo da informa o e do conhecimento em todas as fases evolutivas do capitalismo industrial. Para isso, rediscute algumas características-chave das rela es capital-trabalho ao longo das revolu es industriais anteriores, mostrando como delas emergiram novas rela es produtivas e novas indústrias de fronteira, calcadas na informa o e na cultura, através das quais o capital segue acumulando e, concomitantemente, gerando novos dramas sociais. A apropria o privada da informa o é apontada como o principal problema econ mico, social e político a ser enfrentado neste início de século.

O abuso sexual e os direitos da crian a: respeito, liberdade e dignidade (Sexual abuse and children′s rights: respect, freedom and dignity)
Leda Dantas
Revista Emancipa??o , 2009,
Abstract: Resumo: O artigo procura mostrar como o abuso sexual infantil, ao violar o direito da crian a ao desenvolvimento sexual adequado, implica a viola o de três outros direitos – o respeito, a liberdade e a dignidade (a trilogia da prote o integral), - e as consequências daí advindas para a constru o da subjetividade aut noma. Abstract: The aim of the article is to demonstrate how sexual abuse deprives children from their adequate sexual development and how this implies the violation of three other rights - respect, liberty and dignity (the protection trilogy). In addition, the article discusses the consequences to the development of autonomous subjectivity.

Monbeig e a no o de Complexo Geográfico Monbeig et la notion de complexe géographique
Aldo Dantas
Confins , 2009, DOI: 10.4000/confins.6091
Abstract: Este artigo mostra como, ao longo de sua estadia no Brasil, Pierre Monbeig vai paulatinamente sendo influenciado pelas rápidas mudan as que observa na realidade brasileira, rompe com as velhas amarras da geografia regional francesa e constrói o conceito de complexo geográfico Cet article montre comme, au long de son séjour au Brésil, Pierre Monbeig a été influencé par les rapides changements qu’il observait dans la réalité brésilienne, rompant avec la vieille géographie régionale fran aise, et construisit le concept de complexe géographique This article shows how during his stay in Brazil Pierre Monbeig was influenced by the rapids changes he observed in Brazilian reality, breaking with the old French regional geography, and built the concept of geographical complex
Synthesis and Characterization of a New Cellulose Acetate-Propionate Gel: Crosslinking Density Determination  [PDF]
Patrícia Allue Dantas, Vagner Roberto Botaro
Open Journal of Polymer Chemistry (OJPChem) , 2012, DOI: 10.4236/ojpchem.2012.24019
Abstract: Crosslinking is one of the most commonly reactions used to improve the physical properties of cellulose derivatives. Cellulose Acetate Propionate (CAP) is a commercial ester obtained as a cellulose derivative and it can be used as basis for the synthesis of crosslinked chains as described in this work. Typical used crosslinkers are di-functional compounds, such as dianhydrides or diisocyanate. The formation of polymeric 3D structures as described in this work occurs typically by the reaction of the linear chains bearing free OH groups with crosslinking agents such as dianhydrides. These reactions are used to make a very absorbent material, typically a gel. The syntheses were performed in homogeneous medium with acetate propionate in a very dry atmosphere by employing PMDA (Pyromellitic Dianhydride) and BTDA (3,3’, 4,4’ Benzophenone Tetracarboxylated Dianhydride) as crosslinking agents in a reflux system. TGA analysis has shown the different thermal stability of the gels when compared with CAP. Typical TGA curves have demonstrated the lower stability of the crosslinked chains when compared to CAP as consequence of esther linkages formed in the gels structures. The Mc, which is the value for the molar mass between crosslinkings points in 3D structure, was determined according to Flory-Rehner theory. This important parameter has demonstrated greater reactivity of PMDA in comparison with the BTDA in the reactions conditions’ employed in this work.
A Systematic Review of Factors Influencing Medication Adherence to Hypertension Treatment in Developing Countries  [PDF]
Lipi Dhar, Jaya Dantas, Mohammed Ali
Open Journal of Epidemiology (OJEpi) , 2017, DOI: 10.4236/ojepi.2017.73018
Abstract: Background: Coronary heart disease (CHD), a complication of hypertension, is one of the most important and common causes of morbidity, hospitalisation, and mortality among hypertensive population. In recent decades, increased urbanisation and changes to lifestyle, diet and physical activity in developing countries have led to a major increase in the population incidence of chronic diseases including CHD. Poor medication adherence is one of the leading causes of failure to achieve hypertension control. The objective of this systematic review is to describe the prevalence of non-adherence to anti-hypertensive medications among hypertensive population in developing countries and identify factors associated with it. Methods: A literature search was conducted using the following scholarly electronic databases: Proquest, PubMed, JSTOR and Science Direct. The online search engine, Google Scholar was also used to search for and identify relevant papers. Peer-reviewed full-text articles published in English on hypertensive adults in developing countries that measured adherence to antihypertensive medications and their associations with different factors were eligible for inclusion. The review followed the PRISMA reporting and analytical guidelines for systematic reviews. Results: In all, 42 studies conducted across 19 developing countries were selected for the review. The mean prevalence of medication non-adherence (MNA) among the select hypertensive population was 47.34%. Very few studies were conducted in community settings and except for one, no study examined gender differences in MNA factors. The analysis revealed a range of factors that can influence MNA including low household income and socioeconomic status; knowledge and beliefs of hypertension and its management; avoiding side effects of medications; cost of medication; use of herbal preparations; absence of symptoms; irregular follow-up; and dissatisfaction with the treatment and health services provided. There was a general lack of consideration of role of health system in health care delivery, self-efficacy, cultural barriers, perceived individual risk of hypertension complications. There was also a lack of gender-specific research which is necessary at community settings given the social and economic vulnerabilities faced by women in developing countries that may affect adherence to antihypertensive medications. Conclusions: Future research in developing countries should consider individual risk perceptions, cultural barriers,
