This paper presents a teaching innovation project based on applying technical computing systems as a resource to improve learning in the classroom and as a way of evaluating transversal competences (TC). By these means, students analyze complex kinematic and dynamic mechanical systems in the context of the subject Dynamics of Mechanical Systems of the Master’s Degree in Mechatronics Engineering at Universitat Politecnica de Valencia (Spain). We have observed that the use of such tools improves the students learning on the contents of the subject, allows to acquire the transversal competence related to the analysis and problem solving, and enhances the ability to understand concepts intuitively. Furthermore, results clearly show a positive influence on the use of such tools for improving the professional and ethical commitment to the issues raised.

This study aimed at investigating the level of psychological and social adjustment in relation to the grade and type of learning disability among persons with learning disabilities in the Asir region. The study was applied to a sample of (350) students studying in schools in the Department of Education in Asir. The sample responded to the psychological and social adjustment scale developed as a tool of the study. The results showed that the level of psychological and social adjustment came with a medium degree, as well as the absence of statistically significant differences in the level of psychological and social adjustment students in the basic stage. In light of the results, the researcher recommended preparing awareness programs for teachers of learning disabilities to identify the various indicators that accompany the phenomenon of psychological and social adjustment for persons with learning disabilities. The study also recommends conducting more studies on psychological and social adjustment and its relationship to other variables, such as emotional intelligence.

Nowadays, the close relationship between adolescents and music is a fact reinforced by new technology. Music, in general, reflects values and attitudes in society and serves different purposes in life, however the crisis of values is a constant threat that may be eased by using music as a tool to engage with young people and reinforced ethical values. This work aimed at assessing perceptions of explicit content in pop music by 16-year-old adolescents by means of a questionnaire with a series of short-open questions. The results confirmed a relaxed attitude towards current social values but yet a robust self-claimed personality in young people

The major objective of this study was analyzing the Ethiopian Higher Education quality assessment model in line with another world. The total 46 key informants were purposively selected from the data sources of this study (Ethiopian public HEIs and the Ministry of Education) and interviewed. Document analysis was another instrument. Using descriptive qualitative research design, data were analyzed in themes qualitatively. Literatures describing the higher education quality assessment models were reviewed. The literature on the models of higher education quality assessment generally tends to converge to the general model of higher education quality assessment and tends to diverge from it while it adds many approaches to the dimensions. It is recommended that the Ethiopian system better to be governed by an independent agency that has strong international linkage, and the system should emphasize the need of stakeholders in quality assurance and assessment. Use of diversified methodologies and existence of explicit standards for resource utilization were recommended. Rigorous interdisciplinary and cross-disciplinary peer reviews are strongly recommended in this study.

The positioning of the anchoring points of a Parallel Kinematic Manipulator has an important impact on its later performance. This paper presents an optimization problem to deal with the reconfiguration of a Parallel Kinematic manipulator with four degrees of freedom and the corresponding algorithms to address such problem, with the subsequent test on an actual robot. The cost function minimizes the forces applied by the actuators along the trajectory and considers singular positions and the feasibility of the active generalized coordinates. Results are compared among different algorithms, including evolutionary, heuristics, multi-strategy and gradient-based optimizers.

This study investigates the effect of active recreational maths games (ARMG) on 1st grade male students’ maths anxiety and performance. The sample was divided into two groups: an experimental group (N=28), which was taught maths with ARMG in addition to traditional teaching methods, and a control group (N=30), which was taught with traditional teaching methods only. The ARMG consisted of 24 sessions taking place over a period of two months. Students participated in three sessions per week, each of which lasted 45 minutes. The findings revealed a significant negative correlation (r=-0.482; p<0.05) between maths anxiety and students’ performance. A significant difference (α= 0.05) in maths anxiety and performance emerged between the experimental and control groups. The experimental group obtained lower maths anxiety scores and higher performance scores than the control group. Considering these results, the study proposes several recommendations and suggestions to develop maths teaching with ARMG.

The article is devoted to comparison of the effectiveness of grammar acquisition by adult learners in two types of instruction – based on the traditional PPP (Presentation, Practice, Production) approach and TBL (Task-Based Learning) approach – in ESP university classes. We conducted a qualitative research in which we tried to incorporate grammar instruction in communicative language teaching and for that purpose selected two groups of students (the PPP group and the TBL group). They were taught five topics, each with a focus on particular grammar items. The comparison of the results we obtained showed that students’ achievement in the TBL group increased more substantially than in the PPP group. Also, the majority of students in the TBL group liked learning grammar at the point of need, which we consider particularly important, since it stimulated their motivation and contributed to the acquisition of grammatical structures. When considering the positive aspects of our experience of using TBL and task-based grammar learning in particular, we should first of all point out its learner-centeredness which provides a number of advantages in teaching adult students: the focus on real communication, addressing the students’ needs by putting them into authentic communicative situations, encouragement of students’ responsibility for their own learning, exposure of students to a wide variety of language, including grammar, ability to motivate students.

The information disclosed by the companies in their annual reports reveals much about company’s performance and prospects. Investors take the information as base for decision for investment. Under such circumstance, companies choose to disclose beyond what is mandatorily required. Theories like agency theory, capital need theory and signaling theory support the need of voluntary disclosure. This study is about investigating the extent of Voluntary disclosure in pharmaceutical sector of India which is 3rd in World in terms of Volume of Trade.Objective: To investigate the extent of voluntary disclosure practices prevailing in pharma sector of India, for the year 2010-11 to 2017-18.Significance of the study: This study aims to explore the corporate aspect of pharmaceutical sector. Any growing avenue is a potential opportunity for investors looking for parking their money to get adequate returns. Thus, Indian Pharma sector has come up in flying colors as an avenue for investors to place their money owing to its 100% FDI . Investors have been looking for more and more information from this sector to ensure the safety of funds. Thus the extent of disclosures is worth studying to place a suggestion for the policymakers to introduce the changes in the present set of disclosure practices in pharmaceutical sector.Research Methodology: To understand the extent of voluntary disclosure, a disclosure checklist is constructed and descriptive statistics are carved out to reach the results. The checklist consists of 55 items which are not mandatory by law. The checklist is based on dichotomous scale of ‘1’ and ‘0’ representing presence and absence of the checklist item respectively. The cross sectional analysis is carried out to investigate the year wise and company wise disclosure for eight years.Findings: Though the study observes an increasing trends in the disclosure scores, but the findings are alarming to state that the highest score attained by any company throughout the period of 8 years was 37 (out of 55) not even meeting 80% of the total checklist score. This shows that pharmaceutical sector is not so friendly at disclosures. The probable reasons for such startling results are discussed in the study.

Purpose: The main goal of this paper is to determine if the use of a blended methodology can improve performance and satisfaction of the students, with no additional time cost for teachers. As a second objective, the article attempts to explain observed differences across students in the effect of the methodology on study time based on the theory of optimal decision making. Finally, we sketch a simple cost benefit analysis for the digital learning platform (DLP) used.Design: The teachers combined the traditional classes methodology with the adoption of a DLP in two courses of Microeconomics at an undergraduate level at ESIC Business & Marketing School. Subsequently it is analyzed the impact of this methodology on student satisfaction and performance, as well as on student’s study time using different analytical tools.Findings: students’ grades, at the final exam, increased in a significative way as they spent more time with the DLP and/or when they do more digital assignments at home. Their satisfaction with the blended methodology, and the use of the DLP was quite high for most of students. Their feedback on working time relative to traditional methods showed two extremes, either studying much more or much less. We provide a theoretical explanation for this observation, based on Microeconomic theory. A cost-benefit analysis of the DLP tool at an institutional level suggests that its economic costs are more than justified by the economic benefits of the tool in terms of student’s satisfaction, brand reputation and teachers time saving.Contribution: This document provides a methodology to measure the benefits of an innovative learning methodology using relevant indicators and employing advanced statistical techniques as regression analysis. It also helps us to understand student’s behavior in the face of an educational innovation based on technology. The findings are in line with economic theory.

Characterizing mechanical properties play a major role in several fields such as biomedical and manufacturing sectors. In this study, a stochastic inverse model is combined with a finite element (FE) approach to infer full-field mechanical properties from scarce experimental data. This is achieved by means of non-linear combinations of material property realizations, with a certain spatial structure, for constraining stochastic simulations to data within a non-multiGaussian framework. This approach can be applied to the design of highly heterogenous materials, the uncertainty assessment of unknown mechanical properties or to provide accurate medical diagnosis of hard and soft tissues. The developed methodology has been successfully applied to a complex case study.
