Decoding human brain activities, especially reconstructing human visual stimuli via functional magnetic resonance imaging (fMRI), has gained increasing attention in recent years. However, the high dimensionality and small quantity of fMRI data impose restrictions on satisfactory reconstruction, especially for the reconstruction method with deep learning requiring huge amounts of labelled samples. When compared with the deep learning method, humans can recognize a new image because our human visual system is naturally capable of extracting features from any object and comparing them. Inspired by this visual mechanism, we introduced the mechanism of comparison into deep learning method to realize better visual reconstruction by making full use of each sample and the relationship of the sample pair by learning to compare. In this way, we proposed a Siamese reconstruction network (SRN) method. By using the SRN, we improved upon the satisfying results on two fMRI recording datasets, providing 72.5% accuracy on the digit dataset and 44.6% accuracy on the character dataset. Essentially, this manner can increase the training data about from n samples to 2n sample pairs, which takes full advantage of the limited quantity of training samples. The SRN learns to converge sample pairs of the same class or disperse sample pairs of different class in feature space.

Purpose In accordance with the commitment–trust theory, employee attitudes and behaviours mediate the impact of empowerment on service recovery performance. The purpose of this paper is to extend the self-regulating process model and develop a structural framework that combines empowerment, self-regulation mechanisms (service recovery awareness, job engagement and emotional exhaustion) and post-recovery satisfaction. This framework explores how empowerment can lead to action of frontline employees (FLEs) in service recovery. Design/methodology/approach The authors test the hypotheses by investigating 290 pairs of FLEs and customers, who have service failure experience in the express mail industry, using structure equation modelling. Findings The findings show that empowerment enhances both service recovery awareness and job engagement. On the one hand, service recovery awareness has a positive impact on emotional exhaustion, which has a negative impact on post-recovery satisfaction. On the other hand, job engagement has a positive impact on performance. These results provide the whole picture of the double-edged effects of empowerment on FLEs in service recovery. Practical implications This paper indicates that managers should re-consider approaches to empowerment based on self-regulation process to enhance performance following service failure. Originality/value This study explores the dark side of empowerment in service recovery from a self-regulation perspective.

AbstractCoronavirus (Covid-19) pandemic has imposed a complete shut-down of face-to-face teaching to universities and schools, forcing a crash course for online learning plans and technology for students and faculty. In the midst of this unprecedented crisis, video conferencing platforms (e.g., Zoom, WebEx, MS Teams) and learning management systems (LMSs), like Moodle, Blackboard and Google Classroom, are being adopted and heavily used as online learning environments (OLEs). However, as such media solely provide the platform for e-interaction, effective methods that can be used to predict the learner’s behavior in the OLEs, which should be available as supportive tools to educators and metacognitive triggers to learners. Here we show, for the first time, that Deep Learning techniques can be used to handle LMS users’ interaction data and form a novel predictive model, namely DeepLMS, that can forecast the quality of interaction (QoI) with LMS. Using Long Short-Term Memory (LSTM) networks, DeepLMS results in average testing Root Mean Square Error (RMSE) $$<0.009$$ < 0.009 , and average correlation coefficient between ground truth and predicted QoI values $$r\ge 0.97$$ r ≥ 0.97 $$(p<0.05)$$ ( p < 0.05 ) , when tested on QoI data from one database pre- and two ones during-Covid-19 pandemic. DeepLMS personalized QoI forecasting scaffolds user’s online learning engagement and provides educators with an evaluation path, additionally to the content-related assessment, enriching the overall view on the learners’ motivation and participation in the learning process.

This essay proposes that Socrates practiced various spiritual exercises, induding meditation, and that this Socratic practice of meditation was habitual, aimed at cultivating emotional self-control and existential preparedness. Corntemporary research in neurobiology supports the view that intentional mental actions, including mediation, have a profound impact on brain activity, neuroplasticity, and help engender emotional self-control. This impact on brain activity is confirmed via technological developments, a prime example of how technology benefits humanity, Socrates attains the balanced emotional self-control that Alcibiades describes in the Symposium because of the sustained mental effort he exerts that direct impetus his brain and his emotional and philosophical life. The essay concludes that Socratic meditative practices aimed at manifesting true dignity as human beings within the complexities of a technological world offer a promising model of self-care worthy of embracing today.
