This article will study the cognitive nature of Chinese characters and the neurocognitive basis of the visual perception of Chinese characters in Chinese learning through the dismantling of Chinese character components, adopted into the “Relational Network Theory” (rnt) proposed by Sydney Lamb. We will also discuss the neurocognitive basis of zìg?n, ?? (Bai & Liu, 2006), Grapho-Morphological Awareness of Chinese characters, an abstract concept entangled in the Chinese Character Teaching (cct), and some of the concepts included in Ausubel’ Meaningful Learning Theory, to ground a teaching methodology of the cct in the Chinese International Teaching (cit).

The purpose of this study was to explore the influence of altitude and environmental temperature on muscle mechanical and functional activation after 30' Time Trial run (30' TT). Twenty physical active males (Age= 20.4 ±3.21 years, VO2max= 47.2 ±5.2 ml/kg/min) performed a 30' TT in three different conditions of altitude and temperature: Control Condition [CC] (1137 m.a.s.l. at 26 ±1.5°C), Heat-Low Condition [HLC] (3 m.a.s.l. at 30.5 ±0.6°C), and Cool-High Condition [CHC] (2369 m.a.s.l. at 14.2 ±0.6°C). Tensiomyography (TMG), Countermovement Jump (CMJ), and Delayed Onset Muscle Soreness (DOMS) were measured pre and post running. During the 30' TT, distance, speed, heart rate (HR), rate of perceived exertion (RPE), and thermal index (WBGT) were measured. Results show a significant decrease in body weight and a significant increase in DOMS and jump height in CMJ after running in each condition. TMG responses increased maximum radial muscle displacement (Dm) and decreased muscle contraction time (Tc) both rectus and biceps femoris muscles after running. During the 30' TT, the results did not show a significant difference in RPE, HR, distance, and speed among conditions. In conclusion, altitude and temperature seem not to significantly affect the mechanical and functional responses 30' TT, despite the tendency of HLC to decrease both activation and performance.

This article aims to reconstruct the uses given to the metaphor of the “backhoe” in the political discourse opposed to the second government of Michelle Bachelet in Chile (2014-2018). Along with exposing the way in which the original meaning of this metaphor was efficiently resignified and connoted as an expression of a “destructive” and “undemocratic” political project, this article aims to account for the relevance of rhetorical devices as a tool for political-discursive interaction.
