La enseñanza monumentalista y utilitarista de las causas de la biodiversidad y de las estrategias para su conservación: un estudio sobre la transposi…
2015
Este trabajo estudia la presencia y complejidad en el tratamiento de las causas de la biodiversidad y de las razones para su conservación que realizan manuales escolares de la Educación Secundaria de España. Para ello, se determinó el ámbito conceptual y axiológico que define la comunidad de expertos, se examinó el tratamiento propuesto en el currículo español y se analizaron 50 manuales escolares (27 de la Educación Secundaria Obligatoria –ESO – y 30 del Bachillerato). Los resultados mostraron que el proceso de transposición didáctica vuelve monumentalista la enseñanza de la biodiversidad, ya que olvida las razones de su existencia, y se enriquece de connotaciones biologicistas y utilitari…
Meta-Analysis of Mitochondrial DNA Reveals Several Population Bottlenecks during Worldwide Migrations of Cattle
2014
Several studies have investigated the differentiation of mitochondrial DNA in Eurasian, African and American cattle as well as archaeological bovine material. A global survey of these studies shows that haplogroup distributions are more stable in time than in space. All major migrations of cattle have shifted the haplogroup distributions considerably with a reduction of the number of haplogroups and/or an expansion of haplotypes that are rare or absent in the ancestral populations. The most extreme case is the almost exclusive colonization of Africa by the T1 haplogroup, which is rare in Southwest Asian cattle. In contrast, ancient samples invariably show continuity with present-day cattle …
Visual understanding of divergence and curl: Visual cues promote better learning
2019
Prior research has shown that students struggle to indicate whether vector field plots have zero or non-zero curl or divergence. In an instruction-based eye-tracking study, we investigated whether visual cues (VC) provided in the vector field plot can foster students’ understanding of these concepts. The VC were only present during instruction and highlighted conceptual information about vector decomposition and partial derivatives. Thirty-two physics majors were assigned to two groups, one was instructed with VC about the problemsolving strategy, and one without. The results show that students in VC-condition performed better, responded with higher confidence, experienced less mental effor…
Global age-sex-specific fertility, mortality, healthy life expectancy (HALE), and population estimates in 204 countries and territories, 1950–2019: a…
2020
Background Accurate and up-to-date assessment of demographic metrics is crucial for understanding a wide range of social, economic, and public health issues that affect populations worldwide. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 produced updated and comprehensive demographic assessments of the key indicators of fertility, mortality, migration, and population for 204 countries and territories and selected subnational locations from 1950 to 2019. Methods 8078 country-years of vital registration and sample registration data, 938 surveys, 349 censuses, and 238 other sources were identified and used to estimate age-specific fertility. Spatiotemporal Gaussian…
Parents or Peers? Predictors of Prosocial Behavior and Aggression: A Longitudinal Study
2019
The aim of this longitudinal study was to determine the associations among peer attachment, warmth from the mother and father, strict control by the mother and father, prosocial behavior, and physical and verbal aggression in adolescence. Few longitudinal studies have examined how peer attachment and parenting styles of the mother and father relate to prosocial behavior and aggression. Participants were 192 boys and 255 girls (M = 14.70 years; SD = 0.68) in wave 1. In the study participated 11 schools. For three successive years, participants reported on their fathers’ and mothers’ warmth and strict control, peer attachment, prosocial behavior, and aggression. Structural equations modeling …
Cross-cultural adaptation and psychometric properties of the child perceptions questionnaire 11-14 (CPQ11-14) for the peruvian spanish language
2013
Objectives: Oral-Health-Related Quality of Life (OHRQoL) instruments, such as the Child Perceptions Questionnaire 11-14 (CPQ11-14), are broadly used in oral health surveys around the world. However, there is a lack of these instruments in Spanish language limiting the comparison of OHRQoL outcomes among countries, cultures and ethnic groups. The aim of the present study was to cross-culturally adapt the CPQ11-14 to the Peruvian Spanish language and assess its reliability and validity. Material and Methods: To test the translation and cross-cultural adaptation, 60 children aged 11-to-14-years answered the CPQ11-14 in two pilot tests. After that, the questionnaire was tested on 200 children o…
Thomas Hobbes: la resistencia política al Leviatán
2013
En el presente artículo se presentan cuatro claves de lectura de la obra de Thomas Hobbes desde las que fundamentar una noción de resistencia. Este aporte busca, en otras palabras, crear las condiciones de posibilidad de un debate filosófico ofuscado por el mito recurrente sobre el supuesto monstruo de Malmesbury. Una vez hecho esto, se propone delinear las bases de un enfoque metodológico que parta de dicha noción de resistencia. De ese modo, se fundamentaría el primer paso hacia una apropiación (o expropiación) contemporánea de la matriz hobbesiana de la relación obediencia-seguridad. This article presents four key of readings about Thomas Hobbes's work, from which it supports a particul…
La construcción social de la figura del perpetrador : procesos sociales, luchas políticas, producciones culturales
2020
Los crímenes masivos del siglo XX y de comienzos del siglo XXI han dejado fuertes improntas en las memorias sociales, que siguen elaborando trabajosamente las historias de violencia, los traumas sufridos, las secuelas sociales y los proyectos políticos surgidos en contextos de pos-guerra, pos-dictatoriales y pos-genocidas. Usualmente, estas memorias han dado centralidad a la figura y a la voz de las víctimas. En efecto, ante crímenes muchas veces negados y silenciados por sus responsables, las víctimas debieron legitimar un lugar de escucha en los escenarios transicionales, lidiar con la desconfianza social para que sus relatos sobre lo sucedido fueran reconocidos como verdaderos e interven…
STRENGTH AND POWER PROFILES OF THE LOWER AND UPPER EXTREMITIES IN MASTER THROWERS AT DIFFERENT AGES
2007
Ojanen, T., T. Rauhala, and K. Hakkinen. Strength and power profiles of the lower and upper extremities in master throwers at different ages. J. Strength Cond. Res. 21(1):216-222. 2007.-Thirty-two master athletes (shot put, discus, and hammer throw) were divided into 4 groups according to their age (T40 [40 years of age], 50 [50 years of age], 60 [60 years of age], and 75 [75 years of age]). Twenty-eight age-matched men served as controls (C40 [40 years of age], 50 [50 years of age], 60 [60 years of age], and 75 [75 years of age]). The subjects were tested for maximal isometric strength of the lower and upper extremities. Power was measured by performing jump squats and bench press in the S…
