    In Trilogía sucia de La Habana, Pedro Juan Gutiérrez has defied traditional representations of the sexual body in Latin American literature by depicting eroticism as an agent of meditation and multiplication within an environment of deprivation. The author explores the diverse ways in which eroticism is a means by which to deconstruct subjectivity and provide a political critique against social oppression. The narrative is situated within a socialist Cuban context of surveillance during the Special Period and depicts the many acts of survival its citizens engage in on a daily basis amidst an economic crisis where basic products are scarce. With the absence of material goods, as well as certain political freedoms, the characters in the novel manifest their continuous desires by engaging in a hyper-production of eroticism as a source of power. While recounting personal stories of love and sex, the characters meditate on their social condition in addition to their own private desires. Ultimately, in accord with eroticism as a weapon of social change and critique, Pedro Juan Gutiérrez acknowledges the body traditionally dismissed in dominant Western thought and inscribes new representations where it can be beautiful while being impoverished, artistically tormented and imperfect. Subsequently, this paper analyzes hyper-eroticism as a source of reflection and material agency, leading to new inscriptions of erotic potential as a source for social change.En Trilogía sucia de La Habana, Pedro Juan Gutiérrez ha desafiado representaciones tradicionales del cuerpo sexualizado en la literatura de América Latina al representar el erotismo como un agente de mediación y multiplicación dentro de un ambiente de privacidad. El escritor explora las diversas formas en las cuales el erotismo es un medio por el cual se deconstruye la subjetividad y provee una crítica política contra la opresión social. La narrativa se sitúa dentro de un contexto socialista cubano de vigilancia durante el Periodo Especial y describe los diversos actos de supervivencia que sus ciudadanos llevan a cabo diariamente al estar dentro de una crisis económica en la que los productos básicos son escasos. Con la ausencia de bienes materiales, al igual que de ciertas libertades políticas, los personajes de la novela manifiestan su continuo deseo al participar en una hiperproducción del erotismo como fuente de poder. Al contar historias personales de amor y sexo, los personajes meditan en su condición social, al igual que en sus propios deseos. De acuerdo con el erotismo como arma de crítica y cambio social, Pedro Juan Gutiérrez reconoce el cuerpo, que tradicionalmente ha sido ignorado en el pensamiento occidental dominante, y le inscribe nuevas representaciones donde puede ser bello al mismo tiempo que empobrecido, artísticamente atormentado e imperfecto. Subsecuentemente, este ensayo analiza el hipererotismo como fuente de reflexión y agencia material, que conlleva a nuevas inscripciones del potencial erótico tal como cambio social

    Geographic Variation in Larval Metabolic Rate Between Northern and Southern Populations of the Invasive Gypsy Moth

    Get PDF
    Thermal regimes can diverge considerably across the geographic range of a species, and accordingly, populations can vary in their response to changing environmental conditions. Both local adaptation and acclimatization are important mechanisms for ectotherms to maintain homeostasis as environments become thermally stressful, which organisms often experience at their geographic range limits. The spatial spread of the gypsy moth (Lymantria dispar L.) (Lepidoptera: Erebidae) after introduction to North America provides an exemplary system for studying population variation in physiological traits given the gradient of climates encompassed by its current invasive range. This study quantifies differences in resting metabolic rate (RMR) across temperature for four populations of gypsy moth, two from the northern and two from southern regions of their introduced range in North America. Gypsy moth larvae were reared at high and low thermal regimes, and then metabolic activity was monitored at four temperatures using stop-flow respirometry to test for an acclimation response. For all populations, there was a significant increase in RMR as respirometry test temperature increased. Contrary to our expectations, we did not find evidence for metabolic adaptation to colder environments based on our comparisons between northern and southern populations. We also found no evidence for an acclimation response of RMR to rearing temperature for three of the four pairwise comparisons examined. Understanding the thermal sensitivity of metabolic rate in gypsy moth, and understanding the potential for changes in physiology at range extremes, is critical for estimating continued spatial spread of this invasive species both under current and potential future climatic constraints

    Get PDF
    Gun violence, including that perpetrated by young people, is a pernicious problem for many communities, particularly those facing historically high levels of concentrated disadvantage and disinvestment. To effectively address youth gun violence and establish and maintain peace, communities need stable safety infrastructures and effective interventions.We developed a research-based practice guide to help local governments, law enforcement agencies, and antiviolence organizations determine how to shape their approaches to reducing gun violence perpetrated by young people ages 10 to 25 in gangs or groups. Here, we summarize the guide's recommendations on how to develop effective interventions and build a broader safety infrastructure that supports the success of different partners working to protect young people and communities from gun violence

    A Research-Based Practice Guide to Reduce Youth Gun and Gang/Group Violence

    Get PDF
    While extensive research exists, the field lacks a current and translational synthesis of what works to reduce youth group and gun violence. In response, the Urban Institute developed a research-based practice guide to inform local government, law enforcement, and community-violence-intervention stakeholders as they implement new antiviolence interventions and refine existing ones. To inform the development of the guide, Urban researchers conducted a comprehensive literature synthesis of research on violence reduction interventions and conducted a scan of interventions representing well-known antiviolence models and other innovative strategies. Drawing on the findings from the literature synthesis and scan of practice, the practice guide presents recommendations around nine practice areas related to building an infrastructure to support a multi-faceted antiviolence strategy and implementing effective violence reduction programs

    Dynamic proteomic profiling of extra-embryonic endoderm differentiation in mouse embryonic stem cells

    During mammalian pre-implantation development, the cells of the blastocyst’s inner cell mass differentiate into the epiblast and primitive endoderm lineages, which give rise to the fetus and extra-embryonic tissues, respectively. Extra-embryonic endoderm differentiation can be modeled in vitro by induced expression of GATA transcription factors in mouse embryonic stem cells. Here we use this GATA-inducible system to quantitatively monitor the dynamics of global proteomic changes during the early stages of this differentiation event and also investigate the fully differentiated phenotype, as represented by embryo-derived extra-embryonic endoderm (XEN) cells. Using mass spectrometry-based quantitative proteomic profiling with multivariate data analysis tools, we reproducibly quantified 2,336 proteins across three biological replicates and have identified clusters of proteins characterized by distinct, dynamic temporal abundance profiles. We first used this approach to highlight novel marker candidates of the pluripotent state and extra-embryonic endoderm differentiation. Through functional annotation enrichment analysis, we have shown that the downregulation of chromatin-modifying enzymes, the re-organization of membrane trafficking machinery and the breakdown of cell-cell adhesion are successive steps of the extra-embryonic differentiation process. Thus, applying a range of sophisticated clustering approaches to a time-resolved proteomic dataset has allowed the elucidation of complex biological processes which characterize stem cell differentiation and could establish a general paradigm for the investigation of these processes.This work was supported by the European Union 7th Framework Program (PRIME-XS project grant number 262067 to K.S.L., L.G and C.M.M), the Biotechnology and Biological Sciences Research Council (BBSRC grant number BB/L002817/1 to K.S.L and L.G.), as well as a HFSP grant (RGP0029/2010) and a European Research Council (ERC) Advanced Investigator grant to A.M.A..

    The majority of children with Down syndrome (DS) tend to have frequent bacterial infections including recurrent respiratory infections. Our objective was to evaluate the production of antibodies to pneumococcal polysaccharide antigens after active immunization in DS subjects. IgG antibodies to pneumococcal serotypes (1, 3, 6B, 9V, and 14) were measured before and 6 weeks after immunization with a 23-valent pneumococcal vaccine (Pneumo23®, Pasteur-Merrieux) in 6- to 13-year-old DS children (N = 17) and in aged-matched normal controls (N = 30). An adequate response was defined as a 4-fold increase over baseline or a post-immunization level of specific pneumococcal serotype antibody> or = 1.3 µg/mL. After immunization, all DS children had an increase in post-immunization levels against all serotypes analyzed. A 4-fold or more increase was observed in all DS children concerning serotypes 1 and 14, in 90% of subjects for serotypes 3 and 9V, and in 65% for serotype 6B. Regarding this increase, 8 of the 17 DS children had an adequate response to all serotypes analyzed, 8/17 patients to 4 serotypes and 1/17 to 3 serotypes. However, when we compared post-immunization levels between DS children and controls, we observed lower levels in the former group (P < 0.05) for all serotypes except serotype 3. We conclude that pneumococcal polysaccharide immunization could be beneficial for these DS children.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de PediatriaUniversidade Federal do Ceará Departamento de Toxicologia e Análises ClínicasUniversidade de São Paulo Instituto de Ciências Biomédicas Departamento de ImunologiaUniversidade de São Paulo LIM 36 Faculdade de MedicinaLouisiana State University Health Science Center Department of PediatricsUNIFESP, EPM, Depto. de PediatriaSciEL
