Crisis macroeconómicas y micro mundos del trabajo. La informalidad en Argentina en los últimos 20 años

Si el trabajo informal es una actividad que se incrementa o disminuye en los momentos de crisis, es una discusión que está inscripta en la génesis de los estudios sobre informalidad. Sin embargo poco se ha estudiado en relación a cómo las crisis socio-económicas permean, modifican, alteran, transforman, los lugares de trabajo, a partir de análisis microsociales. En este artículo en primer lugar analizaremos lo sucedido en el mundo del trabajo en la Argentina a partir de la "crisis 2001-2002" y en particular en relación a los trabajadores informales, dando cuenta de las repercusiones de la misma en el mercado de trabajo. En segundo lugar, y a partir deun trabajo de campo que hemos realizado en cuatro ciudades del país, indagaremos los efectos e incidencias de ese fenómeno macrosocial en un escenario de trabajo informal y atípico: las ferias artesanales urbanas

Estudio de la historieta como campo : Las luchas por la construcción de lo nuevo y de lo viejo, en Argentina, desde los noventa

Este trabajo, realizado dentro del equipo de investigación Estudio y Crítica de la Historieta Argentina, que -desde 2001- se constituyó en la Escuela de Ciencias de la Información de la Universidad Nacional de Córdoba, se inscribe en un sub-proyecto para realizar una historia sociológica de la historieta argentina, teniendo como orientación básica la teoría de Pierre Bourdieu. Tras introducir la perspectiva de estudio que adoptamos, consideramos, específicamente, una breve aproximación las luchas para construir lo nuevo y lo viejo desde los noventa hasta la actualidad y a las condiciones de producción de dichas luchas. Los noventa son claves porque en ellos se produce la desintegración de producción industrial, de la industria cultural, de historietas argentinas y el surgimiento de la historieta independiente y una región de relativa autonomía en el campo. La edición de historietas independientes en papel es afectada por la crisis general de 2001/2002, pero con posterioridad a ella se produce una situación donde crecen las regiones autónomas, se quiebra el sistema existente de posicionamientos y va constituyéndose una nueva generación de productores culturales reales que producen una expansión de las formas de narrar y de dibujar historietas. En el proceso de autonomización de regiones del campo tienen gran importancia los blogs, resultando central el sitio www.historietasreales.blogspot.com (hoy www.historietasreales.wordpress.com) como espacio para la publicación de historietas independientes fuera de las normas del sistema de producción previo. Por otro parte, luego de la crisis de comienzos de la década, hay casos particulares de continuidad de empresas de pequeña escala e incluso de editoriales independientes -como Llanto de Mudo en Córdoba-, y la aparición de otras, más omenos independientes, parte de las cuales imprimen historietas aparecidas inicialmente en blogs. También se acentúa el predominio del formato álbum/libro, mientras que intervienen en el mercado los diarios (verbigracia Página 12 con el relanzamiento de la revista Fierro y Clarín con distintas colecciones que incluyen recopilaciones de material local e internacional -basadas en un serie presentada por el diario La Repubblica de Italia-) y a la tradicionales ediciones de recopilaciones y, ahora a algunos libros originales, por De La Flor, se suman la publicación de álbumes por parte de editoriales dedicadas tradicionalmente al libro (Ramdom House, por ejemplo). Una de las conclusiones más importantes es que tras la crisis de los noventa, en un mercado muy reducido, y con buena parte de los creadores culturales reales trabajando para el exterior (incluyendo gran parte de quienes publicaban en la época de la industria editorial), en la década siguiente, en lo que va del 2000, se consolida una nueva historieta argentina, una nueva generación de productores culturales reales -guionistas y dibujantes- con variantes importantes respecto de las posiciones y relaciones en el campo en lo que hace tanto a los creadores, a los editores, distribuidores, espacios de consagración, la constitución de redes sociales entre los distintos integrantes del campo, etc.

Fiji disease resistance in sugarcane: Relationship to cultivar preference in field populations of the planthopper vector Perkinsiella saccharicida

Populations of the planthopper vector Perkinsiella saccharicida on sugarcane cultivars resistant (cvs Q110 and Q87), moderately resistant (cvs Q90 and Q124) and susceptible (evs NCo310 and Q 102) to Fiji disease with known field resistance scores were monitored on the plant (2000-2001) and ratoon (2001-2002) crops. In both crops, the vector population remained very low, reaching its peak in the autumn. The vector population was significantly higher on cultivars susceptible to Fiji disease than on cultivars moderately resistant and resistant to Fiji disease. The number of R saccharicida adults, nymphs and oviposition sites per plant increased with the increase in the Fiji disease susceptibility. The results suggest that under low vector density, cultivar preference by the planthopper vector mediates Fiji disease resistance in sugarcane. To obtain resistance ratings in the glasshouse that reflect field resistance, glasshouse-screening trials should be conducted under both low and high vector densities, and the cultivar preference of the planthopper vector recorded along with Fiji disease incidence.

Monitoring PAHs in the Brisbane River and Moreton Bay, Australia, using semipermeable membrane devices and EROD activity in yellowfin bream, Acanthopagrus australis

Two water quality monitoring strategies designed to sample hydrophobic organic contaminants have been applied and evaluated across an expected concentration gradient in PAHs in the Moreton region. Semipermeable membrane devices (SPMDs) that sequester contaminants via passive diffusion across a membrane were used to evaluate the concentration of PAHs at four and five sites in spring and summer 2001/2002, respectively. In addition, induction of hepatic cytochrome P4501, EROD activity, in yellowfin bream, Acanthopagrus australis, captured in the vicinity of SPMD sampling sites following deployment in summer was used as a biomarker of exposure to PAHs and related chemicals. SPMDs identified a clear and reproducible gradient in PAH contamination with levels increasing from east to west in Moreton Bay and upstream in the Brisbane River. The highest PAH concentrations expressed as B(a)P-toxicity equivalents (TEQs) were found in urban areas, which were also furthest upstream and experienced the least flushing. Cytochrome P4501 induction in A. australis was similar at all sites. The absence of clear trends in EROD activity may be attributable to factors not measured in this study or variable residency time of A. australis in contaminated areas. It is also possible that fish in the Moreton region are displaying enzymatic adaptation, which has been reported previously for fish subjected to chronic exposure to organic contaminants. These potential interferences complicate interpretation of EROD activity from feral biota. It is, therefore, suggested that future monitoring combine the two methods by applying passive sampler extracts to in vitro EROD assays. (C) 2004 Elsevier Ltd. All rights reserved.

Dynamics of a temperature-related coral disease outbreak

During the austral summer of 2001/2002, a coral epizootic occurred almost simultaneously with a bleaching event on the fringing reefs of Magnetic Island (Great Barrier Reef region), Australia. This resulted in a 3- to 4-fold increase in the mean percentage of partial mortality rate in a population of the hard coral Montipora aequituberculata. The putative disease state, ‘atramentous necrosis’, was observed on both bleached and normally-pigmented M. aequituberculata, and presented blackened lesions that spread within days across the colony surface and throughout the population. Diseased portions of the corals were only visible for 3 to 4 wk, with diseased tissues becoming covered in sediment and algae, which rapidly obscured evidence of the outbreak. Diseased colonies were again observed in the summer of 2002/2003 after being absent over the 2002 winter. Analysis of when diseased and bleached corals were first observed, and when and where the mortality occurred on individual colonies, indicated virtually all the mortality over the summer could be attributed to the disease and not to the bleaching. Fluorescence in situ hybridisation (FISH) techniques and cloning, and analysis of the 16S rRNA genes from diseased coral tissue, identified a mixed microbial assemblage in the diseased tissues particularly within the Alphaproteobacteria, Firmicutes and Bacteroidetes. While it is not possible in this study to distinguish between a disease-causing microbial community versus secondary invaders, the bacterial 16S rDNA sequences identified within the blackened lesions demonstrated high similarity to sequences from black band disease and white plague infected corals, suggesting either common aetiological agents or development of a bacterial community that is specific to degrading coral tissues. Temperature-induced coral disease outbreaks, with the potential for elevated levels of mortality, may represent an added problem for corals during the warmer summer months and an added dimension to predicted increases in water temperature from climate change.

The Mental Health Policy Template: Domains and elements for mental health policy formulation

Mental disorders are a major and rising cause of disease burden in all countries. Even when resources are available, many countries do not have the policy and planning frameworks in place to identify and deliver effective interventions. The World Health Organization (WHO) and the World Bank have emphasized the need for ready access to the basic tools for mental health policy formulation, implementation and sustained development. The Analytical Studies on Mental Health Policy and Service Project, undertaken in 1999-2001 by the International Consortium for Mental Health Services and funded by the Global Forum for Health Research aims to address this need through the development of a template for mental health policy formulation. A mental health policy template has been developed based on an inventory of the key elements of a successful mental health policy. These elements have been validated against a review of international literature, a study of existing mental health policies and the results of extensive consultations with experts in the six WHO regions of the world. The Mental Health Policy Template has been revised and its applicability will be tested in a number of developing countries during 2001-2002. The Mental Health Policy Template and the work of the Consortium for Mental Health Services will be presented and the future role of the template in mental health policy development and reform in developing countries will be discussed.

A simulation model of cereal-legume intercropping systems for semi-arid regions II. Model application

Smallholder farmers in Africa practice traditional cropping techniques such as intercropping. Intercropping is thought to offer higher productivity and resource milisation than sole cropping. In this study, risk associated with maize-bean intercropping was evaluated by quantifying long-term yield in both intercropping and sole cropping in a semi-arid region of South Africa (Bloemfontein, Free State) with reference to rainfall variability. The crop simulation model was run with different cultural practices (planting date and plant density) for 52 summer crop growing seasons (1950/1951-2001/2002). Eighty-one scenarios, consisted of three levels of initial soil water, planting date, maize population, and bean population, were simulated. From the simulation outputs, the total land equivalent ratio (LER) was greater than one. The intercrop (equivalent to sole maize) had greater energy value (EV) than sole beans, and the intercrop (equivalent to sole beans) had greater monetary value (MV) than sole maize. From these results, it can be concluded that maize-bean intercropping is advantageous for this semi-arid region. Soil water at planting was the most important factor of all scenario factors, followed by planting date. Irrigation application at planting, November/December planting and high plant density of maize for EV and beans for MV can be one of the most effective cultural practices in the study region. With regard to rainfall variability, seasonal (October-April) rainfall positively affected EV and MV, but not LER. There was more intercrop production in La Nina years than in El Nino years. Thus, better cultural practices may be selected to maximize maize-bean intercrop yields for specific seasons in the semi-arid region based on the global seasonal outlook. (c) 2004 Elsevier B.V.

Population dynamics and gene flow of Helicoverpa armigera (Lepidoptera : Noctuidae) on cotton and grain crops in the Murrumbidgee Valley, Australia

The population dynamics of Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) in the Murrumbidgee Valley, Australia, has been characterized using five highly variable microsatellite loci. In the 2001-2002 growing season, there were very high levels of migration into the Murrumbidgee Valley with no detectable genetic structuring, consistent with previous analyses on a national scale. By contrast, there was significant genetic structuring over the 2002-2003 growing season, with three distinct genetic types detected. The first type corresponded to the first two generations and was derived from local individuals emerging from diapause and their progeny. The second genetic type corresponded to generation 3 and resulted from substantial immigration into the region. There was another genetic shift in generation 4, which accounts for the third genetic type of the season. This genetic shift occurred despite low levels of immigration. During the third generation of the 2002-2003 growing season, different population dynamics was characterized for H. armigera on maize, Zea mays L., and cotton Gossipium hirsutum L. Populations on cotton tended to cycle independently with very little immigration from outside the region or from maize within the region. Maize acted as a major sink for immigrants from cotton and from outside the region. If resistance were to develop on cotton under these circumstances, susceptible individuals from maize or from other regions would not dilute this resistance. In addition, resistance is likely to be transferred to maize and be perpetuated until diapause, from where it may reemerge next season. If low levels of immigration were to occur on transgenic cotton, this may undermine the effectiveness of refugia, especially noncotton refugia.

Prevalence of drug-resistance mutations and non-subtype B strains among HIV-infected infants from New York State

Summary: Prevalence studies indicate that transmission of drug-resistant HIV has been rising in the adult population, but data from the perinatally infected pediatric population are limited. In this retrospective study, we sequenced the pol region of HIV from perinatally infected infants diagnosed in New York State in 2001-2002. Analyses of drug resistance, subtype diversity, and perinatal antiretroviral exposure were conducted, and the results were compared with those from a previous study of HIV-infected infants identified in 1998-1999. Eight of 42 infants (19.1%) had provirus carrying at least 1 drug-resistance mutation, an increase of 58% over the 1998-1999 results. Mutations conferring resistance to nucleoside reverse transcriptase inhibitors, nonnucleoside reverse transcriptase inhibitors, and protease inhibitors were detected in 7.1%, 11.9%, and 2.4% of specimens, respectively. Consistent with previous results, perinatal antiretroviral exposure was not associated with drug resistance (P = 0.70). Phylogenetic analysis indicated that 16.7% of infants were infected with a non-subtype B strain of HIV. It seems that drug-resistant and non-subtype B strains of HIV are becoming increasingly common in the perinatally infected population. Our results highlight the value of resistance testing for all HIV-infected infants upon diagnosis and the need to consider subtype diversity in diagnostic and treatment strategies.

O CORPO COMO UM TEXTO VIVO A Festa e a Dança no Candomblé

Este trabalho é um estudo sobre o papel e a construção do corpo, a partir dos rituais públicos do candomblé. Durante esses rituais, dei-me conta de que o corpo, para essa cultura ágrafa, assumia o papel de um texto, no qual se podiam ler, por meio dos gestos e da dança, as histórias e os valores desse grupo social. Todo esse processo só é possível porque a noção de pessoa no candomblé é pensada como um todo, resultado de todas as partes do corpo, diferentemente da noção disjuntiva presente no ocidente. Todos os sentidos do corpo: olfato, tato, visão, audição e paladar, são onsiderados centros de força, e o processo de iniciação coloca em equilíbrio esses centros. Do mesmo modo que a pessoa é múltipla e construída ao longo do processo iniciático, o corpo manifesta suas múltiplas forças e é construído esteticamente, tornando um texto para ser lido pela sociedade. Dessa forma, o corpo se constrói, nos rituais do candomblé, graças à aprendizagem de valores sociais, culturais e religiosos, que se dá por meio da oralidade, dos atos, gestos e da experiência vivida no quotidiano do terreiro. Nos rituais públicos, através da dança de transe, o iniciado mostrará ao grupo seu estágio espiritual, a visão de mundo do grupo e o ethos de seu povo. A pesquisa de campo foi realizada na Casa de Candomblé Ilé Dara Àse Òsun Eyin, comandada pelo Pai Cido de Òsun Eyin, durante os anos de 2001, 2002 e 2003.(AU)

REPRESENTAÇÕES SOCIAIS DE PROFESSORES DE MATEMÁTICA SOBRE ALUNOS QUE APRESENTAM BAIXO RENDIMENTO: DISCUTINDO POSSIBILIDADES.

Esta pesquisa tem como objetivo descrever e analisar representações sociais construídas por professores de matemática em atuação na Região da Grande São Paulo e que envolvem dificuldades na aprendizagem dessa disciplina. O objeto desta investigação está centrado nas vivências desses professores da educação básica com o ensino de matemática. O conceito de representação social (Moscovici, 1978, 2004; Jodelet, 2001, 2002) e a formação de professores de matemática (Fiorentini e Lorenzato, 2001, 2006; Valente, 2002; Miorim, 1998) foram os pressupostos teóricos que fundamentaram esta pesquisa. Este estudo, realizado com professores de matemática em atuação, teve como principal motivação a possibilidade de contribuir para uma reflexão tanto sobre a formação de professores de matemática em cursos de licenciatura como a respeito dos entraves e avanços na formação pedagógica e suas relações com a aprendizagem dos alunos na disciplina. Os resultados da presente pesquisa apontam para a seguinte constatação: as representações que os professores têm de seus alunos com baixo rendimento os levam a refletir sobre a própria atuação pedagógica e definem a ação a ser tomada perante esses alunos.

Technical efficiency:efficiency, change, technical progress and productivity growth in the national health systems of continental African countries

In May 2006, the Ministers of Health of all the countries on the African continent, at a special session of the African Union, undertook to institutionalise efficiency monitoring within their respective national health information management systems. The specific objectives of this study were: (i) to assess the technical efficiency of National Health Systems (NHSs) of African countries for measuring male and female life expectancies, and (ii) to assess changes in health productivity over time with a view to analysing changes in efficiency and changes in technology. The analysis was based on a five-year panel data (1999-2003) from all the 53 countries of continental Africa. Data Envelopment Analysis (DEA) - a non-parametric linear programming approach - was employed to assess the technical efficiency. Malmquist Total Factor Productivity (MTFP) was used to analyse efficiency and productivity change over time among the 53 countries' national health systems. The data consisted of two outputs (male and female life expectancies) and two inputs (per capital total health expenditure and adult literacy). The DEA revealed that 49 (92.5%) countries' NHSs were run inefficiently in 1999 and 2000; 50 (94.3%), 48 (90.6%) and 47 (88.7%) operated inefficiently in 2001, 2002, and 2003 respectively. All the 53 countries' national health systems registered improvements in total factor productivity attributable mainly to technical progress. Fifty-two countries did not experience any change in scale efficiency, while thirty (56.6%) countries' national health systems had a Pure Efficiency Change (PEFFCH) index of less than one, signifying that those countries' NHSs pure efficiency contributed negatively to productivity change. All the 53 countries' national health systems registered improvements in total factor productivity, attributable mainly to technical progress. Over half of the countries' national health systems had a pure efficiency index of less than one, signifying that those countries' NHSs pure efficiency contributed negatively to productivity change. African countries may need to critically evaluate the utility of institutionalising Malmquist TFP type of analyses to monitor changes in health systems economic efficiency and productivity over time.
