School scientific argumentation and its contribution to learning the topic «health and disease»

El presente artículo pretende contribuir a la discusión sobre los alcances que tiene la argumentación científica escolar en el aprendizaje de las ciencias experimentales y particularmente de los conceptos de salud y enfermedad. En primer lugar, se articulan diversos aportes teóricos sobre la argumentación y se precisa el posicionamiento ilocutivo de este trabajo. Luego se discute una secuencia didáctica, puesta en aula por una de los autores, que persiguió el objetivo de que estudiantes de enseñanza secundaria argumentaran en torno a la enfermedad llamada porfiria eritropoyética congénita apuntando a audiencias específicas. En la secuencia didáctica se acompañó al estudiantado en la producción de sus argumentos y se apoyó la inclusión de cuatro componentes específicas en sus textos: teórica, lógica, pragmática y retórica. Aquí se analizan las producciones escritas, derivadas de una tarea de retextualización, de un grupo de cinco estudiantes seleccionados intencionadamente, con el fin de identificar posibles aportes del proceso de argumentación al aprendizaje de los conceptos de salud en juego.This article intends to contribute to the discussion around the scope of school scientific argumentation in the learning of science and in particular of the concepts of health and disease. In the first place, various theoretical contributions on argumentation are presented, and the illocutionary positioning of this study is specified. Then, a didactical sequence is discussed; the sequence was implemented in the classroom by one of the authors, and had as aim that secondary-school students argued about the disease called congenital erythropoietic porphyria targeting specific audiences. In the sequence, students were accompanied in the production of their arguments and the inclusion of four specific components in their texts was supported: theoretical, logical, pragmatic and rhetorical. Here, the written productions, derived from a task of re-textualisation, of a group of five intentionally selected students are analysed in order to identify possible contributions of the argumentation process to the learning of the concepts of health that were being discussed

Evaluation of Fattening Efficiency of Grazing Bulls through Panel Data Envelop Analysis

The purpose of this paper was to assess fattening efficiency changes in grazing bulls, using panel data envelop analysis in two periods of time. The panel data were compiled by DEAP 2.1, which included the results of a 3-year period from 38 private farms (beef farms) in cooperatives of credits and services. The farms were on prairie savannahs, located on 21.4831 latitude, and -77.3174 longitude, less than 300 meters above sea level, province of Camagüey, mideastern Cuba. The output variable was total sold kg (TSKG), and the input variables were cost of Norgold (CN), fuel kg per ha (FKGXHA), fuel kg per livestock unit (FKGXLU), and unit of human labor force (UHL), which were highly correlated to the output variable. Table 2 shows that technical efficiency (TE), pure efficiency (PEC), and scale sufficiency (SEC), underwent 0.2%, 0.4, and 0.5%, respectively, by the third year of fattening. Technological change (TC) between the second and third years rose to almost 14%, and the total productivity factor (TPF) spiked as farmers became more skilled and experienced, with a 4.9% increase in comparison to the first year, and 13.7% in the second year

SARS-CoV-2 Infection in Multiple Sclerosis

To understand COVID-19 characteristics in people with multiple sclerosis (MS) and identify high-risk individuals due to their immunocompromised state resulting from the use of disease-modifying treatments. Retrospective and multicenter registry in patients with MS with suspected or confirmed COVID-19 diagnosis and available disease course (mild = ambulatory; severe = hospitalization; and critical = intensive care unit/death). Cases were analyzed for associations between MS characteristics and COVID-19 course and for identifying risk factors for a fatal outcome. Of the 326 patients analyzed, 120 were cases confirmed by real-time PCR, 34 by a serologic test, and 205 were suspected. Sixty-nine patients (21.3%) developed severe infection, 10 (3%) critical, and 7 (2.1%) died. Ambulatory patients were higher in relapsing MS forms, treated with injectables and oral first-line agents, whereas more severe cases were observed in patients on pulsed immunosuppressors and critical cases among patients with no therapy. Severe and critical infections were more likely to affect older males with comorbidities, with progressive MS forms, a longer disease course, and higher disability. Fifteen of 33 patients treated with rituximab were hospitalized. Four deceased patients have progressive MS, 5 were not receiving MS therapy, and 2 were treated (natalizumab and rituximab). Multivariate analysis showed age (OR 1.09, 95% CI, 1.04-1.17) as the only independent risk factor for a fatal outcome. This study has not demonstrated the presumed critical role of MS therapy in the course of COVID-19 but evidenced that people with MS with advanced age and disease, in progressive course, and those who are more disabled have a higher probability of severe and even fatal diseas

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Habilidades sociales y filosofía de vida en alumnos de secundaria con y sin participación en actos violentos de Lima Metropolitana

The study was conducted in schools in Lima Metropolitana cones, with a sample of teens and preteens school male and female participants and non participants in violent acts. The instruments used were restructured factor: the Social Skills Scale (EHS) of Gismero. Leaving two factors: the ability to cope with adverse situations and ability to make appropriate requests, and the Philosophy of Life Questionnaire (FV) of Diaz-Guerrero. Leaving factors: Love adversus Power (FV1) and External Factor adversus Internal Factor (FV2). The result shows a low and positive relationship between variables. Regarding the status of students was only found significant differences in (FV1), where students do not aim their violent behavior by love, while the violent power. Preteens have a better management skills to make timely submissions as adolescents. Also their behavior is guided by love while adolescents for power. As to where students live only factor (FV1) differences, where they are predominant in the center of the capital is the power compared to other sectors.El estudio se realizó en colegios de los conos de Lima Metropolitana, con una muestra de adolescentes y preadolescentes escolares de sexos masculino y femenino, participantes y no participantes en actos violentos. Los instrumentos utilizados se reestructuraron factorialmente, quedando la Escala de Habilidades Sociales (EHS) de Gismero en dos factores: Habilidades para enfrentar situaciones desfavorables y Habilidades para hacer peticiones oportunas, y el Cuestionario de Filosofía de Vida (FV) de Díaz-Guerrero en los factores: Amor adversus Poder (FV1) y el Factor Control Interno adversus Externo (FV2). El resultado muestra una relación baja y positiva entre las variables. En cuanto a la condición de los alumnos sólo se encontró diferencias significativas en FV1, donde los alumnos no violentos orientan su comportamiento por el amor, mientras los violentos por el poder. Los preadolescentes presentan un mejor manejo de las habilidades para hacer peticiones oportunas que los adolescentes. Igualmente su comportamiento se orienta por el amor mientras que los adolescentes por el poder. En cuanto al lugar donde viven los alumnos solo el Factor FV1 muestra diferencias, donde lo predominante en el Cono Centro de la capital es el poder en comparación con los otros sectores
