Disentangling help-seeking and giving up: differential human-directed gazing by dogs in a modified unsolvable task paradigm

Dogs are renowned for ‘looking back’ at humans when confronted with a problem, but it has been questioned whether this implies help-seeking or giving up. We tested 56 pet dogs from two breed groups (herding dogs and terriers) in a modified unsolvable task paradigm. One reward type (food or toy) was enclosed in a box, while the respective other reward was accessible. With both reward types, human-directed gazing in relation to the box was significantly positively correlated with interaction with the box, as long as an alternative was available. This suggests that both behaviours served to attain the unavailable reward and reflected individual motivation for the inaccessible vs the accessible reward. Furthermore, we varied whether the owner or the experimenter was responsible for handling the rewards. In the owner-responsible group, dogs rarely gazed at the experimenter. In the experimenter-responsible group, dogs preferentially directed box-related gazing (prior to or after looking at or interacting with the box) at the owner. Still, they gazed at the experimenter significantly longer than the owner-responsible group. Conversely, toy-related gazing was directed significantly more at the experimenter. Thus, dogs adjust their gazing behaviour according to the people’s responsibility and their current goal (help-seeking vs play). Gaze duration did not differ between herding dogs and terriers. We conclude that dogs use gazing at humans’ faces as a social problem-solving strategy, but not all gazing can be classified as such. Dogs’ human-directed gazing is influenced by the social relationships with the persons, situational associations, and context (unsolvable problem vs play).

Essential elements, conceptual foundations and workflow design in crowd-powered projects

Crowdsourcing arose as a problem-solving strategy that uses a large number of workers to achieve tasks and solve specific problems. Although there are many studies that explore crowdsourcing platforms and systems, little attention has been paid to define what a crowd-powered project is. To address this issue, this article introduces a general-purpose conceptual model that represents the essential elements involved in this kind of project and how they relate to each other. We consider that the workflow in crowdsourcing projects is context-oriented and should represent the planning and coordination by the crowdsourcer in the project, instead of only facilitating decomposing a complex task into subtask sets. Since structural models are limited to cannot properly represent the execution flow, we also introduce the use of behavioural conceptual models, specifically Unified Modeling Language (UML) activity diagrams, to represent the user, tasks, assets, control activities and products involved in a specific project.

The Efficiency of a Group Counselling Program Based on a Problem-Solving Strategy in Reducing Psychological Stress Among Adolescent Girls of Divorced Families

This study aimed to reveal the effect of a group counseling program based on a problem-solving strategy in reducing psychological stress among adolescent girls from divorced families. The study sample consisted of (30) students from children of divorced families, in the age group (13-16) years, enrolled in one of the public schools in Zarqa in the second semester 2018/2019. To achieve the objectives of the study, a quasi-experimental design was adopted, in which the sample was divided into two groups: an experimental group (n = 15), that was exposed to the counseling program, and a control group (n = 15) for whom the program was not presented. Both groups underwent a total of two sessions per week, in which the session duration ranged between (45-60) minutes. The results of the current study indicated that there were statistically significant differences between the average performance of the members of the experimental and control groups on the psychological stress test in its psychological, cognitive, and physiological dimensions in favor of the experimental group. This indicates the program’s efficiency in reducing psychological stresses. The study recommended developing more group counseling programs to address psychological, personal, social, and behavioral issues among adolescent girls and boys from divorced families.

Hardware and Software Structure for a Social Robot Capable of Situation Analysis

This paper discusses structuring of hardware and software for an autonomous social robot. It shows that the real-world social robot operations face the challenge of environmental variability and uncertainty of the objective parameters. Thus, a social robot must be capable of situation analysis for better autonomy. We propose a modular distributed structure of the control system. Separate modules monitor the status and control the subsystems of the robot. General coordination of subsystems is provided by the Supervisor module. For the robot to function autonomously, the Supervisor must be capable of situation analysis and its key functions: objective retrieval and analysis, situation description, configuring and strategizing the solution. The robot’s sensory inputs help acquire the objective and its parameters to describe the situation. Description relies on the database of a priori knowledge of the environment and its objects. Analysis is linked to a reduction in the uncertainty of the objective parameters and situation description. For a case study, the paper demonstrates a maze-solving strategy as affected by the situation.

From Reflection to Self-Assessment: Methods of Developing Critical Thinking in Students

The main task of a higher education institution is to prepare a student for professional duties in a rapidly changing world. To effectively perform this task, it is necessary to give students not only knowledge but also to develop the necessary skills and abilities, in particular to develop critical thinking. The purpose of this work was to develop a methodology for the development of critical thinking of students, as well as to investigate its effectiveness. The study used the method of synthesis, which developed a method of developing critical thinking of students. To diagnose the effectiveness of the proposed method used the test "Critical Thinking" L. Starkey adapted by O. Lutsenko. In the study the peculiarities of the development of such critical thinking skills as reflective thinking, self-analysis, awareness of one’s own achievements and shortcomings, choice of problem-solving strategy, use of cognitive models of learning (Socratic dialogue, Paul & Elder taxonomy) are revealed. It was found that the development of critical thinking was achieved through a comprehensive combination of self-assessment and reflection, performing exercises to develop the ability to clearly articulate the problem, find, analyse and interpret relevant information, draw the right conclusions and explanations.The results of this study can be useful to researchers and university professors who are looking for effective methods of developing critical thinking in students.

A STUDY ON NATIVE-LIKE PRONUNCIATION MATTERS ENCOUNTERED BY THIRD-YEAR ENGLISH MAJORS AT THE UNIVERSITY OF FOOD INDUSTRY IN HO CHI MINH CITY

A study of challenges with native-like pronunciation encountered by third-year English majors at HUFI based on theory, previous study results, and the situation of English learning of students specializing in English at HUFI. Pronunciation is an important part of the speech process. Pronunciation should be worked on right from the start of language instruction. Pronunciation aids in the understanding of most information transmitted when communicating with students in English when learning and practicing language skills such as listening, speaking, reading, and writing. Practice is the most important factor in achieving proficiency and fluency. The production and reception of sounds used in speech are referred to as pronunciation. This study is a hybrid of qualitative and quantitative methods. According to a 2021 survey of 50 university students, students understand the importance of English communication skills in general and English pronunciation in particular. However, this does not reflect the reality of student learning. Furthermore, empirical research shows that audiovisual tools, the use of a problem-solving strategy for improving pronunciation, and the method for improving pronunciation in a voice control system are the most effective and widely used methods for improving pronunciation.
