“Yet the Root of the Matter is Not in Them”: Reclaiming the Lost Soul of Inspirational Teaching

This essay by Dirck Roosevelt and Jim Garrison seeks to reclaim the lost soul of teaching by examining distortions wrought upon or threatening it by practice‐based teacher education (PBTE) and like developments. The notion that teaching centers upon mastery of “core” practices understood as routinely skilled performance is inadequate to the almost intractable complexity of teaching. After critiquing PBTE and associated forces, especially the performance assessment edTPA?, Roosevelt and Garrison turn to John Dewey's notion of the teacher as “inspirer and director of soul‐life.” Among other important attributes involved in forming the soul of inspirational teaching, the authors discuss moral perception of the needs, desires, and interests of unique individuals participating in specific situations, and also moral imagination, which allows teachers to see beyond the actual to conceive better possibilities. Roosevelt and Garrison conclude with depictions of two student‐teachers, one troubled by her inability to hear the souls of students and another experiencing the loss of his teaching soul.     

Japan’s English-medium instruction initiatives and the globalization of higher education

This article analyzes a recent initiative of Japan’s Ministry of Education, which aims to internationalize higher education in Japan. The large-investment project “Top Global University Project” (TGUP) has emerged to create globally oriented universities, to increase the role of foreign languages in higher education, and to foster global human resources. The TGUP identifies 37 universities: 13 as “top global universities” intended to compete in the top 100 university world rankings and 24 “global traction universities” intended to lead the internationalization of higher education in Japan. Despite the substantial funding behind this initiative, little research has been conducted to evaluate the potential impact of this policy on language planning in higher education in Japan. This paper addresses this gap in its exploration of the TGUP, including key changes from previous internationalization policies. It then presents an analysis of publicly available documents regarding the policy, collected from all 37 of the participant universities. Findings indicate a positive departure from older policy trends and the emergence of flexible, unique forms of English language education in Japan’s universities.     

Adaptive control of bi-directionally coupled Lorenz systems with uncertainties

The bi-directionally coupled Lorenz systems are linked to the modeling of a coupled double loop thermosyphon system where the mass momentum and heat exchange are both considered. As the key parameters of the system, known as Rayleigh numbers, increase, the system of differential equations predicts typical flow dynamics in a thermosyphon from heat conduction to time-dependent chaos. In many applications including the thermosyphon systems, there are uncertainties associated with mathematical models such as unmodeled dynamics and parameter variations. Also, under the high heat environment for a thermosyphon, there exist external disturbances quantitatively linked to the Rayleigh numbers. All these sources constitute uncertainties to the dynamical system. Our objective is to design adaptive controllers to stabilize the chaotic flow in each thermosyphon loop with unknown system parameters and existence of uncertainties. The controllers consist of a proportional controller with an adaptive gain and a wavelet network that reconstructs the unknown functions representing the uncertainties. Explicit stability bounds and adaptive laws for the control parameters are obtained so that the coupled Lorenz systems are globally stabilized.     

Widely linear estimation for multisensor quaternion systems with mixed uncertainties in the observations

The optimal widely linear state estimation problem for quaternion systems with multiple sensors and mixed uncertainties in the observations is solved in a unified framework. For that, we devise a unified model to describe the mixed uncertainties of sensor delays, packet dropouts and uncertain observations by using three Bernoulli distributed quaternion random processes. The proposed model is valid for linear discrete-time quaternion stochastic systems measured by multiple sensors and it allows us to provide filtering, prediction and smoothing algorithms for estimating the quaternion state through a widely linear processing. Simulation results are employed to show the superior performance of such algorithms in comparison to standard widely linear methods when mixed uncertainties are present in the observations.     

Baseline Intraocular Pressure Is Associated With Subjective Sensitivity to Physical Exertion in Young Males

Purpose: The purposes of this study were to (a) investigate the effect of physical effort (cycling for 60 min at 60 ± 5% of individually computed reserve heart-rate capacity), combined with 2 different levels of cognitive demand (2-back, oddball), on intraocular pressure (IOP) and subjective judgments of perceived exertion (ratings of perceived exertion [RPE]), affect (Affective Valence subscale of the Self-Assessment Manikin [SAM]), and mental workload (National Aeronautics and Space Administration Task Load Index [NASA-TLX]); and (b) ascertain whether baseline IOP, measured before exercise, is associated with individual differences in subjective assessments of effort and affective response during exercise. Method: Seventeen participants (M_age = 23.28 ± 2.37 years) performed 2 physical/cognitive dual tasks, matched in physical demand but with different mental requirements (2-back, oddball). We assessed IOP before exercise, after 2 min of active recovery, and after 15 min of passive recovery, and we also collected RPE and SAM measures during the sessions (28 measurement points). We used NASA-TLX and cognitive performance as checks of the mental manipulation. Results: (a) Intraocular pressure increased after concomitant physical/mental effort, with the effect reaching statistical significance after the 2-back task (p = .002, d = 0.35) but not after the oddball condition (p = .092, d = 0.29). (b) Baseline IOP was associated with subjective sensitivity to effort and showed statistical significance for the oddball condition (p = .03, ?_p² = .622) but not for the 2-back task (F < 1). Conclusions: Results suggest a relationship between IOP and physical/cognitive effort, which could have implications for the management of glaucoma. Additionally, a rapid measure of IOP could be used as a marker of individual effort sensitivity in applied settings.
