Published: February 2021

One of the key criteria to evaluate the development of any country is by her ability to explore computer knowledge. Based on this assertion, this paper examined the effects of Computer-Assisted Oral English Instructional Programme (CAOEIP) on the performance of high schools students in the rural areas of Nigeria. The study focused on two aspects of information and communication technology (ICT) namely animation and digital Video compared with conventional method of teaching. Two hundred and seventy (270) students were drawn from 6 high schools within the rural areas. The experimental groups were administered a Pretest and Posttest with the use of animation and digital video while control group was taught using conventional method. After six weeks of intensive teaching with animation and digital video instructional media, the students were assessed using Oral English Concept Achievement Test (OECAT), an instrument developed by the researcher. ANOVA and t-test were used for the data analysis. Results show that the experimental group taught with animation and digital video (CAOEIP) performed better than those with conventional method. Recommendations were made based on the findings of the study.

Published: February 2021

This paper is a report on the application of a quality improvement technique commonly used in industries to the teaching and learning process in an engineering technology program. An instrument for assessing learning outcomes was designed to determine specific problems that inhibit learning in the program, and their frequencies of occurrence. Based on the data collected, Pareto method was used to determine the vital few, i.e., the few errors committed 80 percent of the time so that class overall performance can be greatly improved by giving deference to these few but most important problems, within limited time and resources. The study cited in this correspondence shows that when Pareto technique is well applied in a teaching/learning process, it results in an improvement of individual performances for an overwhelming majority of the class. This technique is suitable for all science, technology, engineering and mathematics (STEM) disciplines.

Authors: Ritter Kenneth A. , Borst Christoph W. , Chambers Terrence L. 
Published: February 2021

As the interest in Virtual Reality (VR) increases, so does the number of software toolkits available for various VR applications. Given that more games are being made with the Unity game engine than any other game technology, several of these toolkits are developed to be directly imported into Unity. A feature and interaction comparison of the toolkits is needed by Unity developers to properly suit one for a specific application. This paper presents an overview and comparison of several virtual reality toolkits available for developers using the Unity game engine. getReal3D, MiddleVR, and Reality-based User Interface System (RUIS) are analysed for VR interaction and display on multi-projection immersive environments like Cave Automatic Virtual Environments (CAVE)s. MiddleVR was found to have the highest performance and most versatile toolkit for CAVE display and interaction. However, taking cost into account, RUIS is the clear winner as it is available for free under the Lesser General Public License (LGPL) Version 3 license.

Published: February 2021

It is estimated that 2,3 million children today in South Africa are orphaned mainly due to HIV/AIDS.As a result most child-headed households exist .The confounding rise in the number of orphans due to HIV/AIDS has left many children in child-headed households. Most research on child-headed households in South Africa reveal that there are as a result of HIV/AIDS. However there is a danger of assuming that all child-headed households exist only because of the AIDS phenomenon. This paper investigates the circumstances leading to the establishment of child-headed households. The study on which this paper is based was carried out in Thulamahashe circuit, Bushbuckridge district, Mpumalanga. The paper is based on qualitative phenomenological research with 20 children in grades 10 and 11 who live in child-headed households. In the study it was revealed that although HIV/AIDS is a major factor leading to the establishment of child-headed households, there are also other factors such as migrant labour, failure of the extended family to absorb orphaned children, urbanization, poverty and being abandoned by parents that lead to the existence of such homes.

Authors: Sewe Stephen Arato , Oduol Vitalice Kalecha 
Published: February 2021

The commercial viability for E-Band spectrum has attracted a lot of research for the last decade in order to find economic wireless gigabit connectivity that can complement fiber optic cable. This paper has analyzed the usefulness of E-Band point-to-point microwave link in providing wireless backhaul capacities comparable to that of fiber optic cable. In particular, microwave links that utilize the E-band frequencies were set up in three different cities in Kenya i.e. Mombasa (Latitude 04 01 24.10 S, Longitude 039 37 35.10 E) and validated the acceptable propagation and performance of millimeter wave links at E-Band frequencies for distances within and well above the promised limits in the existing literature. Daily occurrences of signal losses closely match the rainfall pattern, and this has been used to further validate the practicality of the experiments. These experiments were successful in verifying that E-Band can be used in Kenya for short range backhaul connectivity and in slightly over stretched path lengths of 3-6 km under clear atmospheric conditions.

Impactful Academic Advising
Authors: Couture Rene 
Published: February 2021

Twenty-one graduate students were asked to reflect on what they remember most from their undergraduate academic advising experiences. Impactful advising is defined here as academic advising that leaves a positive, long-lasting effect on students. In this study, three themes emerged, which depict impactful advising. These advisors were inspiring, had a positive attitude, and were intrusive. Academic advisors do not often realize the long term impact they might leave on students. Students may always pay close attention, but they do feel judgment. It is captivating what students recall several years or decades later, such as encouraging words to a struggling student or belittling the student for going to the wrong office.
As students themselves, academic advisors were likely self-motivated and were interested in finding solutions to their academic and personal problems. Frustration can set in when students arrive at advising appointments with no preparation, questions, or ideas related to how they can maximize their total college experience. Assumptions can easily be made about these students, which can be unfair to the student.

Authors: Jens William Gault , Caples Stephen Carnie 
Published: February 2021

Schools that offer MBA and EMBA programs confer a Master of Business Administration degree and, on most school transcripts, there is no delineation of the delivery methodology of the program. Despite this, there is considerable misunderstanding concerning the differences between the two programs, particularly with regard to the quality of the education received. This study will look to evaluate the current differences between EMBA and MBA programs and attempt to see if there is any substance to the argument that there are quality differences between the two.
Instructional Methods for Limited English Proficient Students in Subject Area Courses
Authors: Woodward Kathleen Elizabeth 
Published: February 2021

This paper studies the question of what instructional strategies are most effective for classrooms with limited English proficient (LEP) students when teaching history content courses. Two specific instructional strategies are researched. The first is the ordering of direct instruction and constructivist activities. Is it best to begin with direct instruction, then move to a constructivist activity or is it best to order lessons in reverse order? The results of the study also offer insight into the efficacy of doing only direct instruction vs. constructivist activities. The second question studied is regarding group vs. individual work. Which type of work results in the most and deepest content knowledge for LEP students and what is useful about each type of work?
A controlled experimental method was used with pre and post quizzes, teacher/researcher observation, and student surveys and interviews. The study finds that student learning is maximized for LEP students when direct instruction precedes a constructivist activity. Using both instructional strategies, but in this order, was shown to be the most effective instructional strategy. Individual vs. group work showed less clear results, but the student interviews provided insight into why LEP students sometimes prefer group work, even if their knowledge gained is not noticeably increased.
Modified Version of Aronovsky Model for Predicting the Performance of Naturally Fractured Oil Reservoirs
Authors: Al-Attar Hazim H. , Lwisa Essa 
Published: February 2021

In this work the mathematical model developed by Aronovsky et. al. for predicting rates of free-water imbibition in naturally fractured oil reservoirs has been modified. The proposed model allows prediction of fractional oil recovery by spontaneous water imbibition in core samples with high accuracy.
The proposed modification involves development of an empirical correlation for the reservoir rock/fluid system-dependent parameter (l) used in Aronofsky model and defined as rate of convergence. The key reservoir rock and fluid physical properties considered in this work include absolute permeability of the rock, porosity, initial water saturation, interfacial tension between oil and water (IFT), viscosity of oil, viscosity of water, and length of core sample.
The accuracy of the modified model is evaluated using the results of laboratory imbibition tests on nine limestone core samples. All imbibition tests were conducted at 90 ° C. The absolute per cent error based on laboratory versus calculated values of (l) is found to range between 0.334 and 3.88.
The proposed model may also be applied for predicting fractured reservoir performance on field scale by simply replacing the core length by matrix block length when the block is totally immersed in water. Additional experimental work and/or field observations would be necessary to verify the reliability of the proposed modification.

Authors: WU HUI-TZU 
Published: February 2021

The purpose of this paper is to conduct an empirical observation of SuperVision, a new name for a new strategy of educational leadership, as well as to utilize the theory of developmental supervision. Glickman, Gordon, and Gordon (2001) state that the definition of SuperVision is identical to leadership for the improvement of instruction. Education leaders view that supervision is essential for successful schools. They also believe that it is crucial to improving supervisory behaviors of school leaders. Therefore, the researcher uses clinical supervision as its method to examine its practices of utilizing the theory of developmental supervision. The findings of this study are: developmental supervision may improve teachers instruction; the supervisory behaviors may improve teachers ability of problem-solving and decision making, and the supervisor may facilitate teachers as life-long learners.

Published: February 2021

This paper focus on a development and implementation of a systematic guided lean and six-sigma approach to solve high rejection rate on part disposal at composite manufacturing for aircraft component industry. The approach is called PaDLeSS which is stand for Part Disposal reduction through Lean and Six Sigma. PaDLeSS is developed from the integration between lean and six sigma tools with a guided by R-DMAIC-S approach and it is focused on the reduction of parts disposal mainly at a composite manufacturing panel for aircraft components. Since a unit price for one composite panel of aircraftcomponent is very high, a systematic approach to improve, control and sustain the process is necessary in order to reduce parts rejection rate in the process, outgoing process and at the customer process. PaDLeSS is devided into two main phases ; development phase and implementation phase. In a development phase, a thorough study was carried out from previous works and match with a requirement needed in part disposal reduction at composite manufacturing for an aircraft panel. The related data related to the parts disposal at the manufacturing line was also analyzed to get actual situation for improvement monitoring. Then, in the implementation phase, a few case studies selected at company A (composite panel for aircraft manufacturing company in Malaysia) for verification and validation purposes. In this paper, the development of PaDLeSS will be presented.
A Scenario-Based Methodology for Cloud Computing Security Risk Assessment
Authors: Khogali Ishraga Mohamed Ahmed , Ammar Hany 
Published: February 2021

Cloud computing has been one of the major emerging technologies in recent years. However, for cloud computing, the risk assessment becomes more complex since there are several issues that likely emerged. In this paper, we survey the existing work on assessing security risks in cloud computing applications. Existing work does not address the dynamic nature of cloud applications and there is a need for methods that calculate the security risk factor dynamically. In this paper, we use the National Institute of Standards and Technology (NIST) Risk Management Framework and present a dynamic scenario-based methodology for risk assessment. The methodology is based using Bayesian networks to estimate the likelihood of cloud application security failure which enables us to compute the probability distribution of failures over variables of interest given the evidence. We illustrate the methodology using two case studies and highlight the significant risk factors. We also show the effect of using security controls in reducing the risk factors.
