Research Article
Author(s):
Journal: International Journal of Education and Practice

Export to    BibTeX   |   EndNote   |   RIS

Abstract
University is more and more faced with the question of ethics these days, especially with regard to student assessment. Some deontologically reprehensible teachers’ practices seem to persist in a setting where the student is in a weak position in the face of a lecturer with a great deal of control and a great capacity for harm. This paper examines the ethics of teachers’ practices during students’ evaluation from a systemic perspective through strategic analysis. Such practices include mark-buying, sexual harassment, and unfair subtraction of marks. The main question in this work is what can explain the persistence of this plight. The data collection process involved the interview of twenty (20) informants, comprising students’ representatives and victims, and personal observations. After having taken stock of the most reported breaches from some lecturers at the University of Maroua, Cameroon, the work scrutinises the reason for their recurrence from three main points: impunity due to the poor application of regulatory provisions, the absence of a moral code in the recruitment procedure of lecturers, and the lecturer’s freedom of impression.
Contribution/ Originality
This study is one of very few studies which have investigated the unethical behavior of teachers in Cameroon universities. It explains the persistence of this unethical behavior trough the weak enforcement of regulations, non-requirement of moral code during recruitment and the feeling free impression of lecturers.

Abstract
Succession planning is a key component in talent management and it is defined broadly as a strategic process within an organisation focusing on identifying, training and developing, mentoring and preparing potential talent for future leadership positions. This study sought to understand the succession planning activities at the agency and the challenges associated with the implementation thereof. The theoretical models of succession planning will form the basis for recommending necessary improvements to the agency. A qualitative research approach was adopted for this study using a self-administered questionnaire to collect primary data from the participants. Secondary data was used as a triangulation strategy to enhance validity and reliability of this study. The scope of this study is limited to the agency and the findings cannot be generalised. The target population in this study was limited to HR managers and managing directors at business units. Therefore there is a potential for further research by extending the target population to include all levels of employees within the agency. This dissertation is the first of its kind within the agency. It will provide ideas for other researchers to expand on this study within the agency.

Author(s):
Journal: International Journal of Education and Practice

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The primary contribution of this paper is the finding that lack of activities and interesting learning areas prepared by the teacher in the classroom may negatively impact children’s social behavior. Classroom design and the teacher’s careful selection of materials to be displayed in each of the learning areas do engage young children in learning activities during learning sessions and their free time. When children group themselves according to their interests in different learning areas, they develop various skills and positive attitude towards each other in their groups and all members of the class. Children engagement in different learning areas in their classroom develop and improve language skills, reading skills, listening skills especially during dramatization, numerical skills, acquire general knowledge in various subjects including sciences and their  mother tongues. In a participative classroom, children learn how to share and take care of the materials in their learning areas. While in their learning centers, children develop manipulative skills, leadership and managerial skills, learn how to tell simple stories, and learn how to work together as a team. A friendly classroom develops an environment that creates a desired children’s social behavior.

Journal: International Journal of Education and Practice

Export to    BibTeX   |   EndNote   |   RIS

Abstract
African countries have initiated programs to generate electricity from renewable sources such as; wind, solar, biomass and hydropower. These initiatives are intended to reduce the carbon footprint of these countries in the wake of heavy dependency on fossil fuels and also provide cheap and accessible electricity to rural areas. These renewable energy programs are expected to deliver regional development and economic empowerment. However, the lack of trained manpower for repair and maintenance of renewable energy technologies devices is likely to result in failure of these technologies, cause losses in revenue and reduction in consumer faith in renewable energy technologies. African universities must be at the core of solving these challenges by training specialized professionals in renewable energy at graduate level and through short courses to meet the increasing demands for qualified human resource to support the sector. Thus to establish the “readiness” of Universities in Africa to offer advanced education and training in renewable energy, a review of all Masters Courses, Ph.D. programs and short courses was carried out. The results identified 21 English-language Masters courses, 3 providers of Ph.D. studies and 9 short courses in or with significant renewable energy content. Generally, there is inadequate advanced training in renewable energy especially at Ph.D. level in Africa thus the need to attract more African Universities to offer such programs at both masters and Ph.D. levels.
Contribution/ Originality
This paper contributes to efforts geared towards underscoring the need for capacity building in renewable energy in Africa. Energy-poverty remains a key issue in Africa with a critical need for capacity building particularly at higher degree level.

Journal: International Journal of Education and Practice

Export to    BibTeX   |   EndNote   |   RIS

Abstract
In a globalizing economy, education is key to competitiveness and economic growth.  Sub-Saharan Africa (SSA) is playing catch up in terms of investing in the human capital needed to participate effectively in the world economy.  The Sub-Saharan region is currently engaged in what has been termed as a “catch-up” period as is reflected in rapid growth in investment in education at all levels, with an increased recognition over the last decade of the need for increased number of graduates at the tertiary level. This expansion has implications on the quality of training and research. Key among the factors that can help enhance quality is supervision. Currently, in many countries in SSA, graduate training and research is largely self-paid and students make significant sacrifices to obtain advanced degrees with the expectation that they would finish on time and secure lucrative careers. With this expectation, supervisors have an enormous task of ensuring quality mentoring. It is a privilege to hold a faculty position and supervise students; nonetheless, this comes with a great responsibility associated with great expectations from the students. The expectations are targeted to supervisors and the institutions of learning.  Although there is still an imbalance on power relationships between supervisors and students, especially in developing countries, supervisors still need to understand and know the student expectations. This way, they can build professionally and healthy long lasting relationships than can spread beyond the supervision period. This paper discusses the issue of supervision, with a focus on different approaches to delivering quality supervision, students’ needs and expectations, and how these can be addressed based on authors’ experiences working at universities from a developing country perspective.
Contribution/ Originality
This paper presents an extensive review that faculty and students will find handy as part of quality graduate training. With the increasing number of graduate students, higher education institutions must hone their role and provide both ethical and leadership to mold excellence in graduate students.

Journal: International Journal of Management and Sustainability

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Recently as contagious diseases such as SARS and MERS etc. have been widely spread across the globe, there is an increased emphasis on the importance of infection management. As hospital infection has been pointed out as a critical issue factor, the need to implement a disease control system in order to control infected patients is becoming necessary. Because hospital systems are information dense systems, utilizing ICT (Information and Communication Technology) and convergence technologies such as RFID (Radio Frequency Identification), Smart Devices, and LBS (Location Based Service) etc. are being proposed as the main methods to implement this system. But because previous research combining hospital data and the area of IT convergence, mainly conducted research with the objective of OA (Office automation) and MIS (Management Information System), there is a limitation of this previous research to be applied to infectious diseases and disease management. To address this, through in-depth interview with professionals, the entry routes of diseases into hospitals were examined and a method to prevent this was proposed in this research. The results of this research confirmed that to prevent diseases from entering a hospital, the most important factor was to increase the access layers of entrance of a hospital to control points of contact. Based on these results, an ICT technology that could be implemented in layers was proposed. It is expected that the results of this research will be helpful to managers and staff of hospital organizations that need to implement control systems to prevent contagious disease infection in hospitals.
Contribution/ Originality
This paper’s primary contribution is to help effectively prevent contagious disease spread by the combination of ICT and administration system of disease.  This study uses an expert interview to investigate key issues.

Journal: International Journal of Mathematical Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
A  scheme is a scheme equipped with a flat connection over a smooth scheme on a base field. The flat connection equipment is a characterization of this scheme to construct through isomorphisms between commutative algebras and formal moduli problems the conformal images of the space-time that are solutions in conformal field theory. If are considered the  schemes and their particular tools, the jets, these determine conformal blocks of space-time pieces that are invariant under conformal transformations. These conformal block of space-time pieces determine a homogeneous degree factor that characterizes the solutions in a complex Riemannian model of the space-time of the field equations to certain tensors of the Weyl curvature. Finally, is demonstrated that the algebra belonging to the  schemes to the mentioned formal moduli problem is the image under a generalized Penrose transform that in the conformal context of many pieces of the space-time, has a structure as objects in commutative rings of CAlgk each one.

Abstract
This paper presents an investigation of the behavior of the multi-order fractional differential equation (MFDE). We derive expressions for the transition curves separating regions of stability from instability for the MFDE generally and the particular case K=2. Employing the harmonic balance technique, we obtained approximate expressions for the n=1 and n=2   transition curves of the MFDE and particularly for the case k=2. We also obtained an approximate analytical solution to the multi-order fractionally damped and forced Duffing-Mathieu equation as well as some special cases computationally using the Homotopy Perturbation Method (HPM).

Journal: International Journal of Natural Sciences Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This experimental study was aimed at evaluating the effect of plastic fibres waste on the physical and mechanical performances of mortars prepared and conserved under hot-dry conditions. The used fibres are recycled polypropylene fibres coming from industrial waste. Two dosages of fibres are used 0.5 and 1 % by weight. The results showed that the exposition of mortars to hot-dry conditions reduces their long-term mechanical strength and increases their shrinkage. Under hot-dry conditions, the reinforcement of mortars by plastic fibres waste has a positive effect on their flexural and compressive strength. The shrinkage of mortars conserved under these conditions is reduced by the addition of plastic fibres waste.
Contribution/ Originality
This study contributes to enrich the fibres mortars researches. For technico-economical and environmental interests, we used local materials coming from natural and industrial waste, such as the sand and fibres. It is one of very few studies which have investigated the effect of hot-dry conditions on the properties of mortars.
