The academic learning viewed from the perspective of John Biggs' «3P model»

El objetivo de este trabajo es presentar la contrastación de un modelo teórico de aprendizaje en el cual se postula que, de acuerdo con el Modelo 3P (Biggs, 1987a, 1993a), las variables de presagio inciden sobre las de producto, mediadas por las de proceso. El modelo ha sido analizado en base a las respuestas dadas por 561 estudiantes portugueses de Educación Secundaria, a un conjunto de instrumentos de medida (Inventario de Estilos de Pensamiento IEP, Batería de Pruebas de Razonamiento Diferencial BPRD, Cuestionario de Estrategias de Autorregulación del Aprendizaje, cuestiones para evaluar las concepciones de aprendizaje, metas escolares y un problema evaluado a partir de la taxonomía SOLO) y el rendimiento final del curso en diferentes áreas académicas. Los resultados confirman las hipótesis formuladas en el modelo postulado en esta investigación y son discutidas algunas consecuencias para la práctica educativa y para el desarrollo de los alumnos.The academic learning viewed from the perspective of John Biggs’ «3P model». The authors tested a theoretical model in which is postulated that, in accordance with the Pattern 3P (Biggs, 1987a, 1993a) the presage variables, impact on those of product, mediated by those of process. The model was contrasted in a group of 561 portuguese students of Secondary Education, using the following instruments: Inventory of Thinking Styles IEP, Battery of Differential Reasoning Tests BPRD, Questionnaire of Self-regulation learning strategies, questions to evaluate the learning conceptions, school goals and a problem evaluated with the SOLO taxonomy. Academic Achievement was measured by the grades obtained by the students in different areas at the end of academic year. The results confirm the hypotheses formulated in the pattern postulated in this investigation. Consequences for the educational practice and the promoting of students learning are discussed

Spectra of heavy-light and heavy-heavy mesons containing charm quarks, including higher spin states for Nf=2+1N_f=2+ 1

We study the spectra of heavy-light and heavy-heavy mesons containing charm quarks, including higher spin states. We use two sets of $N_f = 2 + 1$ gauge configurations, one set from QCDSF using the SLiNC action, and the other configurations from the Budapest-Marseille-Wuppertal collaboration, using the HEX smeared clover action. To extract information about the excited states, we choose a suitable basis of operators to implement the variational method.Comment: 7 pages, 5 figures, Talk presented at the XXIX International Symposium on Lattice Field Theory, Lattice2011, July 11-16, 2011, The Village at Squaw Valley, California, US

Characterisation of retrotransposon insertion polymorphisms in whole genome sequencing data from individuals with amyotrophic lateral sclerosis

The genetics of an individual is a crucial factor in understanding the risk of developing the neurodegenerative disease amyotrophic lateral sclerosis (ALS). There is still a large proportion of the heritability of ALS, particularly in sporadic cases, to be understood. Among others, active transposable elements drive inter-individual variability, and in humans long interspersed element 1 (LINE1, L1), Alu and SINE-VNTR-Alu (SVA) retrotransposons are a source of polymorphic insertions in the population. We undertook a pilot study to characterise the landscape of non-reference retrotransposon insertion polymorphisms (non-ref RIPs) in 15 control and 15 ALS individuals’ whole genomes from Project MinE, an international project to identify potential genetic causes of ALS. The combination of two bioinformatics tools (mobile element locator tool (MELT) and TEBreak) identified on average 1250 Alu, 232 L1 and 77 SVA non-ref RIPs per genome across the 30 analysed. Further PCR validation of individual polymorphic retrotransposon insertions showed a similar level of accuracy for MELT and TEBreak. Our preliminary study did not identify a specific RIP or a significant difference in the total number of non-ref RIPs in ALS compared to control genomes. The use of multiple bioinformatic tools improved the accuracy of non-ref RIP detection and our study highlights the potential importance of studying these elements further in ALS

What do we evaluate in sport mindfulness interventions? A systematic review of commonly used questionnaires

Interest of the study: mindfulness is a concept describing the focus on the present moment, intentionally and without judgement. This approach has only recently been applied to sport psychology. Objectives: the aim of the current review is to investigate which indicators and questionnaires are used in mindfulness research in sport, being specifically interested in mindfulness assessment. Methods: PRISMA guidelines for systematic reviews and the recommendations of the Cochrane Collaboration were used. Literature searches were conducted in Psychinfo, PubMed, EMBASE and the Cochrane Library. Results: From 2, 203 records initially retrieved, 17 articles were included. The results show that mindfulness, anxiety and acceptance are the most commonly studied psychological indicators. The Five Facet Mindfulness Questionnaire is the most frequently used mindfulness scale. We also discuss the possibility of using physiological indicators as complementary assessment. Conclusions: It is recommended to specifically adapt some questionnaires, such is already done with the Sport Anxiety Scale or the Mindfulness Inventory for Sport, for their use in sport psychology

Are anti-ganglioside antibodies detectable in serum from patients with critical illness myopathy and polyneuropathy?

Introduction: Critical illness myopathy (CIM) and polyneuropathy (CIP) are the most common cause of acquired weakness in intensive care units (ICU). However, its exact pathogenesis remains unclear. Abnormal excitability of muscle due to a sodium channelopathy is one of the mechanisms proposed. The aim of this study is to test for the presence of anti-ganglioside antibodies in serum from patients with CIM or both combined CIM/CIP, since there is evidence that they can cause reversible dysfunction of voltage-gated sodium channels.Methods: In a prospective way, we studied 35 patients admitted in ICU by weekly EMG. When positive spontaneous activity (PSA) was detected, a muscle biopsy was performed. Twenty patients met criteria of CIM; five of them also developed overlapping CIP. We did not detect any kind of abnormality in 10 patients during the follow up period. Sera were analyzed for the presence of anti-ganglioside antibodies (Ganglioside-profile 2 Euroline, Euroimmun). Results: Overall, positive reactivity against anti-GT1b was found in one patient with CIM, representing 2.8% (1/35) of the total sample.Conclusion: Reduced percentage of patients affected of CIM or CIM/CIP exhibits positive reactive against anti-ganglioside antibodies. Thus, it could be suggested they do not play a primary role in their pathogenesis. Key words: Critical illness myopathy, critical illness polineuropathy, difficult weaning, channelopathy, muscle fiber inexcitability, anti-ganglioside antibodies  DOI: http://dx.doi.org/10.17268/rmt.2020.v15i01.0

X‐ray fluorescence analysis applied to geochemistry of quartz in Argentina

The growing demand for high-purity quartz in the international market led to the systematic investigation  of the geochemical quality of this mineral in deposits Argentina. This study is a contribution to the scarce  information on the geochemistry of quartz in Argentina. A total of 525 multielemental chemical analyses  were performed with XRF spectrometry in less than 3 months. SiO2   concentration was calculated by  difference from XRF impurity determinations. As a result of this study, 36 sites over 141 sampled deposits  were identied as being of desirable quality. Low-Z oxides, considered critical impurities for quartz, were  determined by atomic absorption spectrometry, only in samples of these selected sites, because of high  XRF detection limits. The analytical results allowed the classication of the quality of quartz according  to its environment and geological genesis. It could be determined that better purity quartz corresponds  to veins far away from the Achala and Alpa Corral batholith and occurs in metamorphic rocks, followed  by pegmatitic quartz from inside the batholith and lastly by quartz of well-known hydrothermal origin.Fil: Perez, D..
