On Learning Interpreted Languages with Recurrent Models

Can recurrent neural nets, inspired by human sequential data processing, learn to understand language? We construct simplified datasets reflecting core properties of natural language as modeled in formal syntax and semantics: recursive syntactic structure and compositionality. We find LSTM and GRU networks to generalise to compositional interpretation well, but only in the most favorable learning settings, with a well-paced curriculum, extensive training data, and left-to-right (but not right-to-left) composition.

Translating Embodied Cognition for Embodied Learning in the Classroom

In this perspective piece, we briefly review embodied cognition and embodied learning. We then present a translational research model based on this research to inform teachers, educational psychologists, and practitioners on the benefits of embodied cognition and embodied learning for classroom applications. While many teachers already employ the body in teaching, especially in early schooling, many teachers’ understandings of the science and benefits of sensorimotor engagement or embodied cognition across grades levels and the content areas is little understood. Here, we outline seven goals in our model and four major “action” steps. To address steps 1 and 2, we recap previously published reviews of the experimental evidence of embodied cognition (and embodied learning) research across multiple learning fields, with a focus on how both simple embodied learning activities—as well as those based on more sophisticated technologies of AR, VR, and mixed reality—are being vetted in the classroom. Step 3 of our model outlines how researchers, teachers, policy makers, and designers can work together to help translate this knowledge in support of these goals. In the final step (step 4), we extract generalized, practical embodied learning principles, which can be easily adopted by teachers in the classroom without extensive training. We end with a call for educators and policy makers to use these principles to identify learning objectives and outcomes, as well as track outcomes to assess whether program objectives and competency requirements are met.

Compassionate Reasoning, the Mind, and Moral Choice

The ethical schools of thought are essential to decision-making for peacebuilding and positive social change. The directives emerging from ethical schools often contradict each other, but Compassionate Reasoning can help resolve these contradictions and guide people in a more coherent direction of thinking and acting. The cultivation of compassion is shown to be a glue that bonds schools of ethics into one enterprise of moral reasoning as seen through several lenses. People who reason together are more adept at problem solving than when reasoning alone, but only if they have cultivated caring and compassionate relationships as a group. Moral reasoning in fierce competition with others, by contrast, retards the discovery of solutions to thorny problems. Compassionate Reasoning encourages collective reasoning rather than isolated and selfish reasoning. Excessive obedience to authority is also one of the most dangerous aspects of the human lower brain. A critical antidote is extensive training in taking the perspectives of others through Compassionate Reasoning.

The indirect effect of high-performance work practices on employees’ performance through trust in management

Purpose The construction industry activities play a key role in achieving socio-economic development and sustaining economic growth in many countries. Increased awareness about the role of human resource management in employee performance has led construction firms to evaluate and focus on high-performance work practices (HPWPs) components, which intend to cultivate employee and organizational performance. This study aims to explain HPWPs affect employee performances through the mediating influence of trust in management in Aqaba, Jordan. Design/methodology/approach A questionnaire survey was administered to collect data among the contractors Grade1 across Aqaba, Jordan. This research was designed as a quantitative study and data were collected at one point of time. In total, 311 questionnaires were returned and only 279 completed questionnaires to test the relationship between HPWPs and employee performances according to the ability, motivation and opportunity conceptualized framework. The partial least squares technique was adopted to test the proposed relationships. Findings The results present that extensive training, rewards based on performance and job security have a significant relationship with trust in management. Trust in management exerts partial mediation effects between HPWPs (extensive training, rewards based on performance and job security) and employee performance (creativity and innovation). Originality/value The findings of the study provide useful and original information to improve the overall performance of construction firms.

Maintained goal-directed control with overtraining on ratio schedules

It is thought that goal-directed control of actions weakens or becomes masked by habits over time. We tested the opposing hypothesis that goal-directed control becomes stronger over time, and that this growth is modulated by the overall action–outcome contiguity. Despite group differences in action–outcome contiguity early in training, rats trained under random and fixed ratio schedules showed equivalent goal-directed control of lever pressing that appeared to grow over time. We confirmed that goal-directed control was maintained after extended training under another type of ratio schedule—continuous reinforcement—using specific satiety and taste aversion devaluation methods. These results add to the growing literature showing that extensive training does not reliably weaken goal-directed control and that it may strengthen it, or at least maintain it.

2021 AAHA Working, Assistance, and Therapy Dog Guidelines

ABSTRACT The guidelines are the first comprehensive consensus report on veterinary healthcare recommendations for working, assistance, and therapy dogs. This category of canine patients includes a broad assortment of animals, some with well-defined functions and others that provide a more generalized support role. The guidelines discuss recommendations for dogs trained for protection, odor/scent detection, service functions for people with diagnosed disabilities or physical limitations, emotional support, and therapeutic intervention. Although the term is often used to describe dogs providing animal-assisted activities, true therapy dogs provide goal-directed therapy, often under the supervision of a healthcare professional such as an occupational therapist or psychologist. Many working dogs undergo extensive training and have rigorous physical demands placed upon them. These factors make working, assistance, and therapy dogs inherently valuable and impose a need for a high level of primary veterinary care as described in the guidelines. Because working dogs have a particularly close relationship with their handlers, a trust relationship between the practice team and the working-dog client is imperative.

A Goal-Directed Account of Action Slips: The Reliance on Old Contingencies

People often keep engaging in behaviors that used to be successful in the past but which are knowingly no longer effective in the current situation, so called action slips. Such action slips are often explained with stimulus-driven processes in which behavior is caused by a stimulus-response association and without information about the outcome of the behavior. This process is contrasted with a goal-directed process in which behavior is selected because it is expected to lead to a desired outcome. Failing to act in line with changes in the outcome, is taken as evidence for stimulus-driven processes. Stimulus-driven processes are assumed to get installed after overtraining and to be deployed under poor operating conditions. In line with this, previous research has found that action slips are more likely to occur after extensive training and when under time pressure. We propose an alternative goal-directed explanation according to which action slips are not caused by a stimulus-driven process, but rather by a goal-directed process that relies on old, no longer accurate, outcome information. In the current study, participants learned four stimulus-response-outcome contingencies during a single (i.e., moderate training) or a four-day training schedule (i.e., extensive training). Afterwards two contingencies were reversed. Results show that after extensive training and when under time pressure, participants not only committed more action slips but also reported more old response-outcome contingencies in line with these action slips. This is consistent with the goal-directed explanation that action slips result from a reliance on old, no longer accurate outcome information.

Gladiators

This paper argues for the professionalism of the gladiators and their combat-spectacles. It examines the rules that governed the combats, the expectations placed on those engaged in them, their extensive training, the organization of those involved and the costs associated with the spectacle. The stress is on the skill, courage, and discipline displayed by the gladiators in combat. It also considers the attitudes of the spectators: their knowledge of the combat techniques and their expectations are key to evaluating the social and cultural impact of the spectacle in Roman society. Given the time, energy, and resources devoted to staging and watching gladiatorial combats, there is little doubt about their social and cultural significance. A variety of evidence is employed, especially epigraphic, in order to reconstruct the events in the arena.

Arable Land Pollution in Ghana: A Look at Agrochemical Plastic Waste Handling among Farmers

The mishandling of agrochemical waste is a major environmental problem causing pollution and a threat to public health. Although the number of agrochemical companies in Ghana continues to grow exponentially, limited efforts are directed toward the proper disposal of plastic bottles after use. Consequently, the study explores the post handling activities of farmers concerning agricultural plastic waste. Using the Birim South District of the Eastern Region of Ghana as the case study, the descriptive statistics are employed to provide answers to the research questions by examining the survey responses of the 120 farmers sampled randomly from an estimated 850 farmers from 4 communities. The results suggest that farmers in the district are aware of the triple rinsing mechanism of ensuring safe disposal. Further, few farmers have had extensive training on the safe usage and disposal of pesticides. In spite, most farmers are willing to burn, bury, and reuse empty agrochemical bottles to properly dispose of after usage. The study reveals a knowledge gap in responsible usage and disposal of agrochemical bottles and the need for an appropriate management system to tackle the challenge.
