This work deals with some important questions about the begginings of Greek prose. Ionian prose, as the more significative literary tradition in philosophy and history, is usually connected to the emergence of rational and critical thinking in Greece. However, the beginnings of Greek prose is involved in many institutional, social, technical and intellectual problems in the sixth century BC.

Japanese English learners have difficulty speaking Double Object than Prepositional Object structures which neural underpinning is unknown. In speaking, syntactic and phonological processing follow semantic encoding, conversion of non-verbal mental representation into a structure suitable for expression. To test whether DO difficulty lies in linguistic or prelinguistic process, we conducted functional magnetic resonance imaging. Thirty participants described cartoons using DO or PO, or simply named them. Greater reaction times and error rates indicated DO difficulty. DO compared with PO showed parieto-frontal (...) activation including left inferior frontal gyrus, reflecting linguistic process. Psychological priming in PO produced immediately after DO and vice versa compared to after control, indicated shared process between PO and DO. Cross-structural neural repetition suppression was observed in occipito-parietal regions, overlapping the linguistic system in pre-SMA. Thus DO and PO share prelinguistic process, whereas linguistic process imposes overload in DO. (shrink)

IntroductionPrevious studies on metacognitive ability were explored using self-report questionnaires that are difficult to adequately measure and evaluate when the capacity for self-reference is undeveloped. This study aimed to validate the Congruency-based Metacognition Scale to measure metacognition and the feeling of confidence abilities and to investigate the development of metacognition during adolescence.MethodsThe CMS was administered to 633 child–parent pairs in Japan. The CMS metacognition score was assessed based on congruency scores between the self-report of the child from a third-person perspective (...) and the parent’s report from the first-person perspective. The CMS self-judgment accuracy score was assessed by the congruency scores between the children’s self-report from the 1PP and 3PP. For both measures, the more distant the 3PP on the self-report was from the 1PP on the parent’s report and child self-report means low ability. An exploratory factor analysis was conducted to examine construct validity and then a confirmatory factor analysis was used. Criterion validity was examined by calculating Pearson’s correlation coefficients with scores on the Beck Cognitive Insight Scale and Autism Quotient. We used intraclass correlation and Cronbach’s alpha to examine the test–retest and internal consistency reliability.ResultsBased on the results of the EFA and CFA, we adopted one factor structure with five items. The CMS metacognition and CMS self-judgment accuracy showed evidence criterion validity, exhibiting significant correlations with the BCIS self-reflectiveness and self-certainty scores, respectively. Regarding to the AQ, only the CMS metacognition score had significant correlations with the social skills and total scale score. The test–retest reliability showed adequate. Adolescents were found to have significantly lower metacognitive ability compared to young adults.ConclusionCMS could be a valid and reliable measure to examine metacognitive abilities for adolescents.

High-spin states have been studied in Pr-135(59), populated through the Cd-116(Na-23,4n) reaction at 115 MeV, using the Gammasphere gamma-ray spectrometer. The negative-parity yrast band has been significantly extended to spin similar to 45 (h) over bar and excitation energy 21.5 MeV, showing evidence for several rotational alignments. The positive-parity yrast band of Ce-135(58), populated through the p4n channel of this reaction, was also populated to spin similar to 38 (h) over bar and excitation energy 18 MeV. Cranking calculations indicate that (...) these nuclei are soft with respect to the triaxiality parameter gamma and that several competing nuclear shapes occur at high spin. (shrink)

Medium- and high-spin states of Pr-134 were populated using the Cd-116(Na-23, 5n) reaction and studied with the GAMMASPHERE spectrometer. Several new bands have been found in this nucleus, one of them being linked to the previously observed chiral-candidate twin-band structure. The ground state of Pr-134 could be determined through establishing a level structure that connects the two previously known long-lived isomeric states. Unambiguous spin-parity assignments for the excited states could be performed based on the known 2(-) spin-parity of the ground (...) state combined with the present experimental data. Intrinsic single-particle configurations have been assigned to the newly observed bands on the basis of the measured B(M1)/B(E2) ratios, alignments, band-crossing frequencies, bandhead spins, the observed single-particle configurations in the neighboring nuclei, and taking into account the predictions of total Routhian surface and tilted-axis cranking calculations.

Muscle synergy analysis via surface electromyography is useful to study muscle coordination in motor learning, clinical diagnosis, and neurorehabilitation. However, current methods to extract muscle synergies in the upper limb suffer from two major issues. First, the necessary normalization of EMG signals is performed via maximum voluntary contraction, which requires maximal isometric force production in each muscle. However, some individuals with motor impairments have difficulties producing maximal effort in the MVC task. In addition, the MVC is known to be highly (...) unreliable, with widely different forces produced in repeated measures. Second, synergy extraction in the upper limb is typically performed with a multidirection reaching task. However, some participants with motor impairments cannot perform this task because it requires precise motor control. In this study, we proposed a new isometric rotating task that does not require precise motor control or large forces. In this task, participants maintain a cursor controlled by the arm end-point force on a target that rotates at a constant angular velocity at a designated force level. To relax constraints on motor control precision, the target is widened and blurred. To obtain a reference EMG value for normalization without requiring maximal effort, we estimated a linear relationship between joint torques and muscle activations. We assessed the reliability of joint torque normalization and synergy extraction in the rotating task in young neurotypical individuals. Compared with normalization with MVC, joint torque normalization allowed reliable EMG normalization at low force levels. In addition, the extraction of synergies was as reliable and more stable than with the multidirection reaching task. The proposed rotating task can, therefore, be used in future motor learning, clinical diagnosis, and neurorehabilitation studies. (shrink)

Resumen Nombrar implica ejercer el poder sobre lo nombrado, involucra coacción y coerción social. La atribución de nombres, adjetivos, designaciones, favorece la taxonomía cognitiva, pero también socio-ideológico-cultural. Cuando una Institución al servicio del Estado nomina, esas denominaciones tienen consecuencias en los sujetos nombrados. En México, a través de las prácticas semiótico- discursivas se llevó a cabo esta edificación del concepto de discapacidad con importantes implicaciones. El objetivo de este artículo es describir la construcción discursiva, a través de la historia de (...) la nominación de la discapacidad para vincular este hecho con el imaginario social de México y revisar las implicaciones socio-ideológicas resultantes. Para efectuar un primer acercamiento, estudiamos los términos con que se designa la discapacidad en los Censos de población y vivienda realizados por el organismo responsable y sustentamos la exposición del proceso a partir de las propuestas de Lyons y Serrano sobre las implicaciones semánticas vinculadas con la designación; de Thiebaut respecto a la articulación semántica del nombre con la pragmática del texto, y con apoyo en Koike para la co-construcción del significado.
