The Landless Voices Database: A Trajectory from Cultural Studies to Pedagogical Impact

This article initially addresses the conception of the web-enabled database Landless Voices (VIEIRA, 2003) as a contribution to Cultural Studies and, crucially, to the understanding of the relational workings of Brazil’s complex and regionally diverse culture of landlessness, and to the validation of the cultural self-expression of the sem-terra/Sem Terra. Secondly, it analyzes speculative data obtained from prospective primary teachers being trained at the Federal University of Paraná, Brazil, on the contribution of the database to the pedagogical context. The main findings are that the three predominant types of impact, using Meagher’s terminology (2013, p. 5) are conceptual (new knowledge), cultural (revising misconceptions) and instrumental (future development of pedagogic practices). It then moves to empirical research on social impact, understood as the contribution of academic research to non-academic users, more specifically to its presumably main beneficiaries – the Sem Terra learners themselves. The findings of these first exploratory workshops with learners in four rural schools in settlements in the states of Paraná and São Paulo, respectively in October and November 2013, are that the database broadens their educational resources and empowers a historically marginalized social segment. This article confirms, however, that impact is not a punctual activity (MEAGHER, 2013) and concludes on the need for continuous interaction with learners for the pedagogic impact of academic research to be generated[1].[1] This is part of Landless Voices Impact Enhancement Project, developed by Professor Else R. P. Vieira (Principal investigator) and co-researchers: Dr. Sônia Schwendler (Federal University of Paraná, UFPR) and Professor Bernardo Mançano Fernandes (São Paulo based UNESCO’s Chair in Territorial Development and Education for the Countryside; MA in Territorial Development in Latin American and Caribbean of the São Paulo State University – UNESP, and PhD Programme in Geography, Presidente Prudente Campus), both honorary researchers at Queen Mary’s Department of Iberian and Latin American Studies.

Your Diamond Dreams Cut Open My Arteries

Critics have called Else Lasker-Schüler the greatest of all German women poets and one of the finest Jewish poets. This large and representative selection of translations by Robert P. Newton, supplemented by a biographical and critical introduction and a selected bibliography, was the first substantial presentation of her works in English at its original publication in 1982

Phadiatop Infant in the Diagnosis of Atopy in Children with Allergy-Like Symptoms

Background and Objective. Allergy-like symptoms such as wheezing and eczema are common in young children and an early diagnosis is important to initiate correct management. The objective of this study was to evaluate the diagnostic performance of Phadiatop Infant, an in vitro test for determination of early sensitisation to food and inhalant allergens. Patients and Methods. The study was conducted, retrospectively, using frozen sera from 122 children (median age 2.7 years) admitted to the hospital with suspected allergic symptoms. The doctor's diagnosis atopic/nonatopic was based on routinely used procedures such as clinical evaluation, SPT, total and allergen-specific IgE antibodies. The performance of Phadiatop Infant was evaluated in a blinded manner against this diagnosis. Results. Eighty-four of the 86 children classified as atopic showed a positive Phadiatop Infant test. Thirty-six were classified as nonatopic, 32 of who had a negative test. With a prevalence of atopy of 70% in this population, this gives a sensitivity of 98%, a specificity of 89%, and a positive and negative predictive value of 95% and 94%, respectively. Conclusion. The results from the present study suggest that Phadiatop Infant could be recommended as a complement to the clinical information in the differential diagnosis on IgE-mediated disease in young children with allergy-like symptoms

Bound states near a moving charge in a quantum plasma

It is investigated how the shielding of a moving point charge in a one-component fully degenerate fermion plasma affects the bound states near the charge at velocities smaller than the Fermi one. The shielding is accounted for by using the Lindhard dielectric function, and the resulting potential is substituted into the Schr\"odinger equation in order to obtain the energy levels. Their number and values are shown to be primarily determined by the value of the charge and the quantum plasma coupling parameter, while the main effect of the motion is to split certain energy levels. This provides a link between quantum plasma theory and possible measurements of spectra of ions passing through solids.Comment: Published in EPL, see http://epljournal.edpsciences.org/articles/epl/abs/2011/09/epl13478/epl13478.htm

Adenosine, lidocaine and Mg^2+ improves cardiac and pulmonary function, induces reversible hypotension and exerts anti-inflammatory effects in an endotoxemic porcine model

Introduction The combination of Adenosine (A), lidocaine (L) and Mg^2+ (M) (ALM) has demonstrated cardioprotective and resuscitative properties in models of cardiac arrest and hemorrhagic shock. This study evaluates whether ALM also demonstrates organ protective properties in an endotoxemic porcine model. Methods Pigs (37 to 42 kg) were randomized into: 1) Control (n = 8) or 2) ALM (n = 8) followed by lipopolysaccharide infusion (1 μg∙kg^-1∙h^-1) for five hours. ALM treatment consisted of 1) a high dose bolus (A (0.82 mg/kg), L (1.76 mg/kg), M (0.92 mg/kg)), 2) one hour continuous infusion (A (300 μg∙kg^-1 ∙min^-1), L (600 μg∙kg^-1 ∙min^-1), M (336 μg∙kg^-1 ∙min^-1)) and three hours at a lower dose (A (240∙kg^-1∙min^-1), L (480 μg∙kg^-1∙min^-1), M (268 μg∙kg^-1 ∙min^-1)); controls received normal saline. Hemodynamic, cardiac, pulmonary, metabolic and renal functions were evaluated. Results ALM lowered mean arterial pressure (Mean value during infusion period: ALM: 47 (95% confidence interval (CI): 44 to 50) mmHg versus control: 79 (95% CI: 75 to 85) mmHg, P <0.0001). After cessation of ALM, mean arterial pressure immediately increased (end of study: ALM: 88 (95% CI: 81 to 96) mmHg versus control: 86 (95% CI: 79 to 94) mmHg, P = 0.72). Whole body oxygen consumption was significantly reduced during ALM infusion (ALM: 205 (95% CI: 192 to 217) ml oxygen/min versus control: 231 (95% CI: 219 to 243) ml oxygen/min, P = 0.016). ALM treatment reduced pulmonary injury evaluated by PaO(2)/FiO(2) ratio (ALM: 388 (95% CI: 349 to 427) versus control: 260 (95% CI: 221 to 299), P = 0.0005). ALM infusion led to an increase in heart rate while preserving preload recruitable stroke work. Creatinine clearance was significantly lower during ALM infusion but reversed after cessation of infusion. ALM reduced tumor necrosis factor-α peak levels (ALM 7121 (95% CI: 5069 to 10004) pg/ml versus control 11596 (95% CI: 9083 to 14805) pg/ml, P = 0.02). Conclusion ALM infusion induces a reversible hypotensive and hypometabolic state, attenuates tumor necrosis factor-α levels and improves cardiac and pulmonary function, and led to a transient drop in renal function that was reversed after the treatment was stopped
