Exploring Peer Collaborative Writing in EFL Secondary Mixed-age Classrooms
Based on the beliefs (assertions) that students benefit socially and cognitively from interacting with peers of different ages, mixed-age (M-A) classrooms have attracted much attention from educators, education policymakers, and researchers. Nevertheless, research into the role and impact of age grouping in second (L2) and foreign language (FL) learning is rather scarce. Moreover, a growing body of research has shown that by linking oral and written modes, collaborative writing (CW) aids language learning. However, the majority of studies have investigated adult and young adult students, and very few were conducted with secondary and high school students. Based on our knowledge, no study has explored CW in M-A secondary school classrooms. With these research gaps in mind, and drawing predominantly on documentary analysis of student written work, the present study examined CW of 28 students of English as a foreign language (EFL) aged 12 to 15 old learners who jointly wrote a comic. The findings point to limitations of M-A peer interaction suggesting that there is a threshold for the younger learners in terms of benefiting from CW with their older partners. Similarly, the findings suggest that the extent to which OS benefit is rather limited
Biomecà nica de l’arquitectura muscular i potència mecà nica de salt en joves
Objectiu: Analitzar les relacions i diferències en potència mecĂ nica en salt i l’arquitectura de la musculatura extensora de les extremitats inferiors en subjectes joves segons el sexe i el nivell d’activitat fĂsica. Metodologia: S’han realitzat 3 estudis: 2 de metodològics i 1 d’aplicat. Al Primer es van comparar 2 mètodes d’avaluaciĂł de la potència de curta durada basats en salt i en pedaleig. Al Segon es va comparar el mesurament de la potència en salt mitjançant un mètode directe davant d’alguns d’indirectes. Al Tercer es va analitzar la potència de salt i l’arquitectura de la musculatura extensora d’extremitats inferiors en una poblaciĂł d’homes i de dones distribuĂŻts cada un en 3 subgrups amb diferent condiciĂł fĂsica. Hi van participar 244 subjectes: 9 universitaris; 161 homes aspirants a una Facultat de Ciències de l’Esport; 12 jugadores de voleibol de la SelecciĂł Espanyola; 12 dones i 7 homes jugadors de voleibol de Primera DivisiĂł Nacional; 10 dones i 10 homes de Ciències de l’Esport; 12 dones i 11 homes universitaris sedentaris. Resultats i discussiĂł: A l’Estudi 1 les potències obtingudes amb tots dos mètodes correlacionaven entre si, però amb el salt es van obtenir valors gairebĂ© 3 vegades superiors. A l’Estudi 2 la punta de potència amb equacions correlacionava amb l’obtingut amb plataforma de forces. No obstant això, totes les equacions han subestimat la potència respecte a la plataforma. A l’Estudi 3, la variable d’arquitectura que millor ha correlacionat amb el salt ha estat el gruix muscular del vast lateral (VL). La poblaciĂł d’homes ha mostrat potències mĂ©s grans en salt, majors gruixos i longituds de fascicles en VL, i angles de penniaciĂł en VL i gastrocnemi lateral (GL) que no pas la de dones. Les dones han mostrat majors longituds de fascicles en GL i gastrocnemi medial (GM) que no pas els homes. Entre subgrups de diferent sexe els d’homes han mostrat mĂ©s capacitat de salt que els respectius de dones. Entre els subgrups del mateix sexe s’han trobat diferències en potència de salt, però no en arquitectura muscular. Homes i dones semblen presentar diferències de partida en algunes variables d’arquitectura, que els podrien condicionar diferències en el rendiment fĂsic en algunes activitats. Les majors potències dels homes sobre les dones al costat de les diferències en gruix i longitud de fascicles del VL entre els dos i les correlacions trobades fan pensar que l’arquitectura d’aquest ventre condiciona la potència de salt i explica el major rendiment dels homes davant les dones en el salt, però no explicaria les diferències entre subgrups del mateix sexe. Conclusions: Les diferents arquitectures dels subjectes explicarien les diferències en la capacitat de salt entre homes i dones, però no les diferències entre subgrups del mateix sexe. El VL Ă©s el ventre que major implicaciĂł ha mostrat amb la potència en salt
EEMI - An Electronic Health Record for Pediatricians: Adoption Barriers, Services and Use in Mexico
The use of paper health records and handwritten prescriptions are prone to preset errors of misunderstanding instructions or interpretations that derive in affecting patients’ health. Electronic Health Records (EHR) systems are useful tools that among other functions can assists physicians’ tasks such as finding recommended medicines (and their contraindications) and dosage for a given diagnosis, filling prescriptions and support data sharing with other systems. By using an EHR many errors can be avoided. This paper presents EEMI (Expediente Electrónico Médico Infantil), a Children EHR focused on assisting pediatricians in their daily office practice. EEMI functionality keeps the relationships among diagnosis, treatment, and medications. EEMI also calculates dosages and automatically creates prescriptions which can be personalized by the physician. The system also validates patient allergies to avoid prescription of any pharmaceutical with alerts. EEMI was developed based on the experience of pediatricians in the Monterrey metropolitan area. This paper also presents the current use of EHRs in Mexico, the Mexican Norm (NOM-024-SSA3-2010), standards for the development of electronic medical records and its relationships with other standards for data exchange and data representation in the health area. This system is currently in production. It uses novel technologies such as cloud computing and software services

Dynamic Limits on Planar Libration-Orbit Coupling Around an Oblate Primary
This paper explores the dynamic properties of the planar system of an
ellipsoidal satellite in an equatorial orbit about an oblate primary. In
particular, we investigate the conditions for which the satellite is bound in
librational motion or when the satellite will circulate with respect to the
primary. We find the existence of stable equilibrium points about which the
satellite can librate, and explore both the linearized and non-linear dynamics
around these points. Absolute bounds are placed on the phase space of the
libration-orbit coupling through the use of zero-velocity curves that exist in
the system. These zero-velocity curves are used to derive a sufficient
condition for when the satellite's libration is bound to less than 90 degrees.
When this condition is not satisfied so that circulation of the satellite is
possible, the initial conditions at zero libration angle are determined which
lead to circulation of the satellite. Exact analytical conditions for
circulation and the maximum libration angle are derived for the case of a small
satellite in orbits of any eccentricity.Comment: Submitted to Celestial Mechanics and Dynamical Astronom
Internações por diabetes mellitus nas Regiões e Unidades Federativas do Brasil: tendência temporal entre 2011 e 2019.
Objetivo: Analisar a tendĂŞncia temporal das internações ocorridas no Sistema Ăšnico de SaĂşde (SUS), nas Regiões e Unidades Federativas no Brasil, com o diagnĂłstico principal de diabetes mellitus (DM), entre 2011 e 2019. MĂ©todo: Estudo ecolĂłgico com análise de sĂ©ries temporais dos dados secundários provenientes do Sistema de Informações Hospitalares do Sistema Ăšnico de SaĂşde (SUS), referentes a população brasileira. Foram incluĂdas os residentes no Brasil que foram internados por DM (CID10 - E10 ao E14). A tendĂŞncia temporal foi analisada por regressĂŁo linear generalizada de Prais-Winstern, com nĂvel de significância de 5%. Resultados: De 2011 a 2019, foram registradas 1.239.574 de internações por motivo de Diabetes mellitus no Brasil, representando 1,2% do nĂşmero de internações por todas as afecções de saĂşde (103.051.010) para o perĂodo no paĂs. A Taxa de Internações (TI) por DM no SUS foi de 6,77/10 mil habitantes com tendĂŞncia decrescente (IC95%=6,44-7,10; valor p=0,01; r²=0,97; CoefB= -0,13). A TI por RegiĂŁo (Gráfico 1) foi maior nas Regiões Nordeste (TI=7,97; valor p=0,01; r²=0,64; CoefB= -0,15) e Sul (TI=7,60; valor p=0,01; r²=0,76; CoefB= -0,41). A tendĂŞncia da TI apresentou-se decrescente para a maioria das Regiões, sendo estacionária na RegiĂŁo Norte (valor p=0,80). A TI por Unidade Federativa (UF), nos estados do PiauĂ e MaranhĂŁo, na RegiĂŁo Nordeste, e RondĂ´nia e Roraima, na RegiĂŁo Norte foram acima de 10,00/10mil habitantes, com tendĂŞncia crescente no MaranhĂŁo (TI=11,83; valor pConclusĂŁo: A tendĂŞncia temporal foi decrescente, com diferenças segundo RegiĂŁo/UF
Prognostic role of serum cytokeratin 19 fragments in advanced non-small-cell lung cancer: association of marker changes after two chemotherapy cycles with different measures of clinical response and survival
Prognostic implication of serum cytokeratin 19 fragments (CYFRA 21-1) was explored in 60 advanced NSCLC patients, whereas in 45 patients assessable for serological response a â©ľ35% CYFRA 21-1 decline after two chemotherapy cycles was strongly associated with non-progression (NP), defined as a sum of objective response (OR)+stable disease (P<0.0001) and survival (P=0.0002). Association of OR with survival was not significant. In multivariate survival analysis, â©ľ35% marker decline and radiological NP status were found as major determinants of prolonged survival with RR: 0.37 (P=0.01) and 0.63 (P=0.01), respectively. In advanced NSCLC patients, NP reflects therapeutic efficacy better than traditional OR. CYFRA 21-1 â©ľ35% decline seems to be a reliable surrogate marker of treatment efficacy in terms of survival
