Factors influencing on the Academic performance of students in business education

This study analyses the factors of students’ commitment and teaching context which influence on the academic performance of students. The study findings reveal that the students’ commitment, teaching context and students’ academic performance are in satisfactory level. Students’ commitment has positive moderate influence and teaching context have weak positive influence on the academic performance of students. The regression analysis shows that both students’ commitment and teaching context explain 21.4% of variation on the academic performance of students, while 78.6% of variation in the academic performance of students is unexplained by these both variables. These unexplained variations may be caused from personality, family background, prior knowledge, physical and psychological competencies, cognitive skills of students and learning habit etc. Therefore the teacher needs to improve present teaching context in alliance with personal factors of students in order to improve students’ learning in business education in a university

Stress Management competencies among banking sector managerial employees in the Batticaloa district

This paper examines the level of stress management competencies among banking sector managerial employees. Further, this study explores the level of effect personal factors on stress management competencies. The stress management competencies is measured using the dimension of respectful and responsible behavior, managing and communicating work, managing individual in a team and managing difficult situations. The data is collected using questionnaires from 84 managerial employees who are randomly selected from the banks in the Batticaloa district. The data is analyzed using the statistical techniques of descriptive statistics, one sample t test, independent sample t test, ANOVA test, correlation and cross tabulation techniques. The study found that the stress management competencies of managerial employees are high level in the bank. The dimension of respectful and responsible behavior, managing and communicating work and managing difficult situations are also fall in this level. And the managing individual in a team is very high level. The study also shows that there is strong positive impact on each other competencies. Comparing personal profile of managers with their competencies shows that, female managerial staffs have significance competencies in managing difficult situation than male. Married employees have more respectful and responsible behavior than single. Joint family setting has more managerial competencies than separate. Age and experience have weak negative effect on the managerial competencies of people. Training time did not significant effect on the managerial competencies of staff. Income levels of managerial staffs have significance difference in stress management competencies. Further the type tasks involved, designation of managerial employees also have differences in stress management competencies. Hence, the special attention have to be taken by management in designing and implementing stress management training to enhance the stress management competencies of banking sector staff

Comparative review of methods for stability monitoring in electrical power systems and vibrating structures

This study provides a review of methods used for stability monitoring in two different fields, electrical power systems and vibration analysis, with the aim of increasing awareness of and highlighting opportunities for cross-fertilisation. The nature of the problems that require stability monitoring in both fields are discussed here as well as the approaches that have been taken. The review of power systems methods is presented in two parts: methods for ambient or normal operation and methods for transient or post-fault operation. Similarly, the review of methods for vibration analysis is presented in two parts: methods for stationary or linear time-invariant data and methods for non-stationary or non-linear time-variant data. Some observations and comments are made regarding methods that have already been applied in both fields including recommendations for the use of different sets of algorithms that have not been utilised to date. Additionally, methods that have been applied to vibration analysis and have potential for power systems stability monitoring are discussed and recommended. � 2010 The Institution of Engineering and Technology

Effectiveness of Conference Feedback on College Students’ Composition in the English as a Second Language (ESL) Context

This article examines the negotiation teacher-student feedback conferences in a college writing course. The conferences were held in groups with one teacher and six participants who agreed to take part in this study. The study includes the right for the teacher to offer advice and to criticize, which is often considered to be threatening in more normal contexts. However, as the data analysis shows, participants also interact in ways that challenge the common norms, some of which might be considered more conventionally attacking. The article argues that conference feedback should be analyzed at the level of interaction (Haugh and Bargiela-Chiappini, 2010) and that situated and contextual detail is relevant to its analysis. The study suggests that teachers’ in a second language writing classroom should provide conference feedback so that student understand what the teachers’ expect of them and, provides a useful theoretical framework for doing so. The conclusion of the study draws on real-life talk-in-interaction (from transcribed recordings), the participants’ perspectives (from focus groups and interviews) and situated detail (from field-notes) to produce a contextualized and nuanced analysis.

Feedback’s Efficiency: To what extent does the teacher-student relationship affect ESL student’s writing using conference feedback

Teachers’ understandings of feedback probably influence the type and quality of feedback that they provide and also enhances teacher-student relationship in the classroom setting. A qualitative study design was adopted, whereby six undergraduates participated in focus group interviews. Participants were first asked to write an argumentative essay. They then submitted the draft for the teacher’s feedback. After two days of correcting the papers, conference feedback was provided by the teacher. The focus group interview was audio-taped and transcribed, as well as written performance scores from students’ writing samples, and audio-taped teacher-student writing conferences. Teachers’ understandings of feedback were strongly focused on enhancing relationship with the student instead of improving learning. Similar factors are expected in other contexts, though agreement rates should reflect local policy priorities and cultural values. Emerging themes provided insights into value of conference feedback in academic writing

Process Performance Analysis in Large-Scale Systems Integrating Different Sources of Information

Process auditing using historical data can identify causes for poor performance and reveal opportunities to improve process operation. To date, the data used has been limited to process measurements; however other sources hold complementary information about the process behavior. This paper proposes a new approach to root-cause diagnosis, which also takes advantage of the information in utility, mechanical and electrical data, alarms and diagrams. Its benefit is demonstrated in an industrial case study, by tackling an important challenge in root-cause analysis: large-scale systems. This paper also defines specifications for a semi-automated tool to implement the proposed approach. © 2012 IFAC
