Development of a Bring Your Own Device (BYOD) eLearning conceptual framework for private secondary Schools in Dubai, United Arab Emirates

The objectives of this dissertation were (1) to study the impact of grade 9 students’ achievement in Science and Mathematics in BYOD schools and Non-BYOD schools, (2) to examine the variation in grade 9 students’ achievement in Science and Mathematics based on gender in BYOD schools and NonBYOD schools, and (3) to develop a BYOD eLearning Conceptual Framework for private secondary schools in Dubai, UAE based on documentary research and confirm it with an empirical research. The population of this quantitative non-experimental design included 21,127 students and 1,241 teachers. The sample size was 1,800 students and 120 teachers. Probability sampling method was used in this research study. The data collecting instruments were self-administered questionnaires. The data were analysed using both descriptive and inferential statistical methods such as percentile, mean, independent t-test, Chi-Square test and discriminant analysis. Major Findings : 1) The student’s achievement in Mathematics and Science in BYOD Schools vs Non-BYOD shows there was a significant difference in both subjects score with BYOD schools students score are higher (Mean score, Mathematics – BYOD School – 78.01, Non-BYOD School – 74.50, Science – BYOD School – 77.84, Non-BYOD School – 74.01) ; 2) On comparison of students’ achievement in Mathematics and Science with their genders in BYOD Schools show there were significant difference whereas the Non-BYOD Schools shows the differences were not significant and ; 3) the BYOD critical factors such as Teaching Methods (TM), Learning Methods (LM), Technology Usage (TU), and Evaluation Methods (EM) of BYOD Schools have a positive impact on student achievement, and hence the BYOD eLearning Conceptual Framework found to be effective. The “new knowledge” found in the field of eLearning Methodology was the detailed finding of the influence of TM, LM, TU and EM on student’s Science and Mathematics achievements of BYOD schools. “Academic Progression” which is used as proof of the expertise of a researcher in the field of eLearning Methodology was the body of knowledge that the researcher acquired with regard to BYOD eLearning factors which can impact student achievement in Science and Mathematics with this empirical research.
TOXICITY OF ABAMECTIN AND HYDRAMETHYLNON TO INSECTICIDE-SUSCEPTIBLE AND RESISTANT STRAINS OF GERMAN COCKROACH ( DICTYOPTERA : BLATTELLIDAE )

The toxicities of two new insecticides, hydramet.hylnon and abamectin, were evaluated against one susceptible and seven insecticide-resistant strains of 81attella gennanica. (L.) Both materials proved to be potent insecticides against the susceptible strain. There was no difference in toxicity, based on LTfoO values, of hydramethylnon between resistant and susceptible strains in a feeding bioassay. Likewise. there was no significant cross-resistance to abamectin (based on LOw values) detected in seven resistant strains by topical application. However, two strains did show significant cross-resistance to ablllnectin based on LD9! values. These results suggest that in German cockroaches cross-resistance to hydramethylnon may be rare and cross-resistance to abamectin may be limited.
Magnetostriction Measurement by Using Dual Heterodyne Laser Interferometers

Electrical machines and transformers have a core built out of laminations of ferromagnetic materials. A portion of the vibrations and noise of these devices is due to magnetic forces and magnetostriction arising from the magnetic core. Magnetic forces are well known, and analytical methods are extensively used to calculate them. Magnetostriction can be defined as the deformation of the ferromagnetic material in the presence of a magnetic field. Unlike magnetic forces, magnetostriction shows a rather complex behavior. It varies for every material, and it depends on the applied magnetic field and external pressure. Therefore, magnetostrictive behavior of every material needs to be determined experimentally by means of strain measurements. Strain gauge measurement techniques have been used before at the Electrical Energy Laboratory (EELAB), Ghent University, Ghent, Belgium. In this paper, a new measurement method using dual heterodyne laser interferometers is proposed to overcome the drawbacks of the old method. The proposed measurement setup and the working principles are explained. The possibility to apply both techniques on one and the same sample can also reveal some interesting results about the quality of both techniques.
A well‐mixed, polymer‐based microbioreactor with integrated optical measurements

We describe a 150 µL microbioreactor fabricated in poly(methylmethacrylate) (PMMA) and poly(dimethylsiloxane) (PDMS) to cultivate microbial cell cultures. Mixing is achieved by a small magnetic stir bar and fluorescent sensors are integrated for on‐line measurement of pH and dissolved oxygen. Optical transmission measurements are used for cell density. The body of the reactor is poly(methylmethacrylate) with a thin layer of poly (dimethylsiloxane) for aeration, oxygen diffuses through this gas‐permeable membrane into the microbioreactor to support metabolism of bacterial cells. Mixing in the reactor is characterized by observation of mixing of dyes and computational fluid dynamics simulations. The oxygenation is described in terms of measured KLa values for microbioreactor, 20–75/h corresponding to increasing stirring speed 200–800 rpm. Escherichia coli cell growth in the microbioreactor is demonstrated and the growth behavior is benchmarked with conventional bench‐scale bioreactors, flasks and tubes. Batch culture experiments with Saccharomyces cerevisiae further demonstrate the reproducibility and flexibility of the microbioreactor system. © 2005 Wiley Periodicals, Inc.
An Alternative to Conventional Rock Fragmentation Methods Using SCDA: A Review

Global energy and material consumption are expected to rise in exponential proportions during the next few decades, generating huge demands for deep earth energy (oil/gas) recovery and mineral processing. Under such circumstances, the continuation of existing methods in rock fragmentation in such applications is questionable due to the proven adverse environmental impacts associated with them. In this regard; the possibility of using more environmentally friendly options as Soundless Chemical Demolition Agents (SCDAs) play a vital role in replacing harmful conventional rock fragmentation techniques for gas; oil and mineral recovery. This study reviews up to date research on soundless cracking demolition agent (SCDA) application on rock fracturing including its limitations and strengths, possible applications in the petroleum industry and the possibility of using existing rock fragmentation models for SCDA-based rock fragmentation; also known as fracking. Though the expansive properties of SCDAs are currently used in some demolition works, the poor usage guidelines available reflect the insufficient research carried out on its material’s behavior. SCDA is a cementitious powdery substance with quicklime (CaO) as its primary ingredient that expands upon contact with water; which results in a huge expansive pressure if this CaO hydration reaction occurs in a confined condition. So, the mechanism can be used for rock fragmentation by injecting the SCDA into boreholes of a rock mass; where the resulting expansive pressure is sufficient to create an effective fracture network in the confined rock mass around the borehole. This expansive pressure development, however, dependent on many factors, where formation water content creates a negative influence on this due to required greater degree of hydration under greater water contents and temperature creates a positive influence by accelerating the reaction. Having a precise understanding of the fracture propagation mechanisms when using SCDA is important due to the formation of complex fracture networks in rocks. Several models can be found in the literature based on the tangential and radial stresses acting on a rock mass surrounding an SCDA charged borehole. Those fracture models with quasi-static fracturing mechanism that occurs in Mode I type tensile failure show compatibility with SCDA fracturing mechanisms. The effect of borehole diameter, spacing and the arrangement on expansive pressure generation and corresponding fracture network generation is important in the SCDA fracturing process and effective handling of them would pave the way to creating an optimum fracture network in a targeted rock formation. SCDA has many potential applications in unconventional gas and oil recovery and in-situ mining in mineral processing. However, effective utilization of SCDA in such application needs much extensive research on the performance of SCDA with respect to its potential applications, particularly when considering unique issues arising in using SCDA in different applications.
The administrative control system of substance abuse managed care.

OBJECTIVE This article searches for the dimensions of the administrative structures in outpatient substance abuse managed care that control the behavior of agency providers. It also ascertains how these dimensions, and several financial mechanisms, affect key aspects of the providers services: the average number of sessions of care that are delivered, the rate of completion of care, and the (estimated) rate at which clients control their substance use. DATA SOURCES The data were collected in 1999 for this investigation. STUDY DESIGN These data come from a nationally representative, cross-sectional sample of individual contracts between outpatient drug treatment providers and the Behavioral Health Managed Care Organizations (BHMCOs) that are empowered to regulate the delivery of services. Provider responses are analyzed here. DATA COLLECTION METHODS Factor analyses at a contract level examine the structural dimensions of the control system. Multivariate analyses at the same level rely on generalized linear models to predict the dependent variables by the structural dimensions and financial mechanisms. FINDINGS The factor analyses suggest that there are six multiple variable structural dimensions. The multivariate analyses suggest that the dimension that mandates follow-up of discharged clients tends to relate to more sessions of care and perhaps a higher rate of service completion. Most other dimensions are found to relate to fewer sessions of care, lower rates of service completion, or lower rates of control of substance abuse. No structural dimension relates to all dependent variables. Financial mechanisms evince varying relations to the sessions of care. They rarely relate to the other dependent variables. CONCLUSION The results generally suggest that providers, payers, or policymakers might affect service provision by selecting BHMCOs that stress particular structural dimensions and financial mechanisms. However, managed care contracts most heavily rely on structural dimensions that restrict treatment sessions and fail to predict superior client outcomes.
The chromogranin-secretogranin family.

The members of the chromogranin–secretogranin family of peptide hormones, biogenic amines, and neurotransmitters are enclosed within vesicles in the neuroendocrine system and a variety of neurons. These granins, the chief of which is chromogranin A, participate in sympathoadrenal activity and serve as markers of neuroendocrine tumors, especially pheochromocytoma.
Investigating university-industry partnership of higher engineering education using cause-effect analysis and multi-criteria decision making: A Malaysian perspective

In recent years, there has been growing interest towards integrating industry into the teaching and learning processes. This is due to many factors including increased concerns about the mismatch between the skills and abilities of the talent pool, strengthening partnership and improving quality of engineering education. Thus, greater emphasis on the teaching and learning processes to enhance the students’ learning experience leads to the university-industry partnership to the forefront interest of the university. On the other hand, exclusion of industry’s engagement in the teaching and learning processes have been identified as the main source of chronic criticism on the higher engineering education segment in recent years. This study demonstrates a research model that hypothesised the influence of teaching and learning domains on the university-industry partnership towards enhancing the learning experience of the engineering students. Using the structural equation modelling (SEM), the hypothesis was tested on the primary data collected from 212 communities of the industry. Furthermore, the study investigated the preference of industry on the type of linkages to foster university-industry partnership using analytical hierarchy process (AHP). The results revealed that nine out of the thirteen hypotheses had significant associations including six direct paths and three indirect effects in the model. The findings indicated the need for industry-university partnership in three main constructs including cooperation in education, the mobility of people and intellectual enhancement. Moreover, internship programme was the important linkage in achieving the overall university-industry partnerships goals, followed by the staff training programme, academic development, consultancy work, student learning activity and publication activity. In summary, the study demonstrates that teaching and learning relevance could be enhanced through optimizing industry’s enrichment activities into the learning process, improving the measures for accreditation in narrowing the gap between theory and practice and proactively improving the quality of teaching by exploring the staff training programmes.
Multimarket Contact in Vertically Related Markets

Abstract We analyze collusion in two comparable market structures. In the first market structure, only one firm is vertically integrated; there is one independent firm in the upstream industry and another independent firm in the downstream industry. In the second market structure, there are only two vertically integrated firms that can trade among themselves in the intermediate good market. The second market structure mimics markets like the California gasoline market where firms are vertically integrated through refinery and retail markets. We rank these two market structures in terms of ease of collusion and show that while under a reasonable collusive sharing rule collusion is not possible in the market with one vertically integrated firm, collusion is possible in the market structure with two vertically integrated firms. We conclude that vertical multimarket (multilevel) contact facilitates collusion and if vertical mergers are suspected to lead to subsequent vertical mergers in an industry, then they should receive higher antitrust scrutiny relative to single isolated vertical mergers.
EDUCATION VERSUS EXPERIENCE: WHICH MATTERS MORE FOR INDONESIAN BANK DIRECTORS?

The purpose of this paper is to assess the effects of board of directors’ education and experience on firmfinancial performance. Based on the cross-sectional analysis of 30 publicly-listed Indonesian banks, it isfound that both directors’ education and experience positively influence bank profitability, measured withReturn on Assets ratio. The results of this study support Hambrick and Mason’s Upper-Echelon theory.Based on the research findings, Indonesian banks are recommended to take experience and education intoaccount when organizing board members—with more emphasis on the former due to the moresignificantimpact it has. Furthermore, banks should also be encouraged to invest more in their human capital byfacilitating further education of their board members.

Lower plasma apolipoprotein A1 levels are found in Parkinson's disease and associate with apolipoprotein A1 genotype

The discovery of novel plasma‐based biomarkers could lead to new approaches in the treatment of Parkinson's disease (PD). Here, we explore the role of plasma apolipoprotein A1 (ApoA1) as a risk marker for PD and evaluate the influence of APOA1 promoter variation on plasma ApoA1 levels. Plasma ApoA1 and the single‐nucleotide polymorphism, rs670, were assayed in a discovery cohort (cohort 1) of 301 PD patients, 80 normal controls (NCs), and 165 subjects with other neurodegenerative diseases, as well as a cohort (cohort 2) of 158 PD patients from a second clinical site. Additionally, rs670 was genotyped in a third cohort of 1,494 PD and 925 NC subjects from both clinical sites. Compared to both normal and disease controls, PD patients have lower plasma ApoA1 (P < 0.001 for both comparisons). Moreover, in PD patients, plasma ApoA1 levels are correlated with genotype at the APOA1 promoter polymorphism, rs670. Specifically, lower plasma ApoA1 levels were found in rs670 major allele (G) homozygotes in both cohort 1 (P = 0.009) and in a replication cohort (cohort 2; n = 158 PD patients; P = 0.024). Finally, evaluating rs670 genotype frequencies in 1,930 PD cases versus 997 NCs, the rs670 GG genotype shows a trend toward association (odds ratio: 1.1; P = 0.10) with PD. Our results are compatible with a model whereby circulating ApoA1 levels may be useful in risk‐stratifying subjects for the development of PD, with higher ApoA1 levels suggesting relative protection. Future studies evaluating modulation of ApoA1 as a novel therapeutic strategy in PD are warranted. © 2014 International Parkinson and Movement Disorder Society
Comparison of 5′-inosine monophosphate and p-nitrophenyl phosphate degrading activities among red, pink, and white muscle fibers of cultured carp

As part of a study to clarify the differences in the temporal change in K-value among fish species, the temporal change in K-value and the 5′-inosine monophosphate (5′-IMP) and p-nitrophenol phosphate (p-NPP) degracling activities in the red, pink, and white muscle fibers in the dorsal muscle of the carp were compared. The temporal change in K-value was fastest in red, followed by pink, and white muscle fibers, at both 0°C and 32°C. Moreover, the 5′-IMP and p-NPP degrading activities were highest in red, followed by pink, and white muscle fibers at near optimum pH concentrations. The 5′-IMP degrading activity at pH 7.0 had a positive correlation with the increasing rate of K-values at 32°C for all types of muscle fibers. These results suggest that differences in increasing rates of K-values between red, pink, and white muscle fibers corresponded to the 5′-IMP degrading activities.
Comparison of Pressure Ulcer Treatments in Long‐term Care Facilities: Clinical Outcomes and Impact on Cost

This study compared clinical outcomes and nursing labor costs associated with (a) balsam Peru, hydrogenated castor oil, and trypsin (BCT) ointment; (b) BCT + Other; and (c) Other treatments in 2014 wound episodes occurring in 861 patients (mean 2.34 wounds/patient). Treatment with BCT ointment or BCT + Other was associated with a higher healing rate (P < .05). No Stage 1 or 2 ulcer treated with BCT ointment progressed, compared with 13.8% treated with BCT + Other and 13.4% treated with Other. The reported mean duration of treatment and time to heal were shorter for ulcers treated with BCT ointment, but differences did not reach significance, possibly because of the variability in reported treatment times. Mean daily nursing labor costs were lower for treatment with BCT than Other ($50.8 vs $61.7, P < .05). These data suggest that treatment of Stage 1 or 2 ulcers with BCT may be associated with shorter treatment time and time to heal and a potential reduction in treatment-related nursing labor costs.
Explicating the Corporate Governance Mechanisms of Shari’ah Compliant Companies

The paper attempts to assess and examine the disclosure of the mechanisms of the corporate governance (CG), namely, board matters, nomination matters, audit matters, remuneration matters, communication matters, and risk management matters, of Shari’ah Compliant Companies (ShCCs) for a six-year period from 2008 until 2013. By using the weighted disclosure analyses approach, CG index was developed. The study examines the annual reports of a sample of 1,122 ShCCs which was selected based on the top 500 firms (by market capitalisation) for 2008 until 2013. In this study, SPSS was applied to assess the CG disclosure. Based on the descriptive analysis, the result indicates a remuneration matters (mean: 0.55) score higher than the other mechanisms; this was followed by audit matters (mean: 0.49). The study also found that, the average disclosure level of ShCCs was relatively low. Hence, the result has important implications for the enhancement of the CG disclosure of ShCC for a wider acceptance and reputation enhancement.
Variability of human linkage data.

It is customary to summarize linkage data on a given pair of loci in man by lod scores which define the maximum likelihood estimate of a recombination rate 6 [1]. Apart from sampling errors, there are two causes of variability in such data. Biological variability subsumes sex, race, age, and other factors which determine recombination in a doubly heterozygous individual. Technical variability includes errors of parentage, phenotyping, recording, calculation of lods, and interpolation to estimate 6 as well as departure of the corresponding measure of goodness of fit from its assumed distribution. Here we examine linkage data for 1,665 pairs of loci in 1,699 papers published up to the end of 1976. The purpose is to determine the frequency and cause of significant variability preparatory to construction of linkage maps. Preliminary steps have been described elsewhere [2, 3]. Errors in somatic cell assignments due to multiple isolation of the same clone, misclassification of chromosomes, and premature publication will not be considered.
The Persistence of Fee Dispersion among Mutual Funds*

Previous work shows large differences in fees for S&P 500 index funds. We expand this work to compare fees across all US equity funds using two methods, regression-based pricing models and holdingsbased fund matching, to control for fund heterogeneity. We find economically large, robust, persistent and pervasive fee dispersion in the mutual fund industry. Importantly, fee dispersion exists among the largest funds (top TNA quintile) as well as among institutional funds. Most surprisingly, fee dispersion has noticeably increased over the last twenty years, even as the industry has experienced enormous growth in capital invested and the number of funds. Time-series regressions show that yearly changes in fee dispersion are positively related to market returns and changes in household participation in the fund industry and negatively related to the size of the mutual fund industry.
