The Impact and Challenges of Education and Administration in VET on Economic Growth in Oman During the COVID-19 Period

The COVID-19 pandemic is still a major global health problem that had substantial consequences on people’s daily lives. This paper evaluates the impact of education and institutional management on Vocational Education and Training (VET) schools in Oman during the COVID-19 period. The purpose of this study is to understand the impact of the COVID-19 pandemic and identify possible challenges that may affect its impact on economic growth. This qualitative research is used as the main methodology of the study. Qualitative data are collected through convenience sampling of 108 VET college students and staff using interviews and questionnaires. The study revealed that the administration plays an important role in economic growth. The students suggested that the national educational administration of the government of Oman plays an important role in their education and that this in turn churns out industry-ready individuals who will impact the economic growth. The government’s role, especially financially post-pandemic lockdown, will be a critical determinant of VET’s impact on economic growth. This study introduces a new perspective on education administration from the perspective of students and staff of VET colleges.
Sleep and Late-Onset Alzheimer’s Disease: Shared Genetic Risk Factors, Drug Targets, Molecular Mechanisms, and Causal Effects

Late-onset Alzheimer’s disease (AD) is associated with sleep-related phenotypes (SRPs). The fact that whether they share a common genetic etiology remains largely unknown. We explored the shared genetics and causality between AD and SRPs by using high-definition likelihood (HDL), cross-phenotype association study (CPASSOC), transcriptome-wide association study (TWAS), and bidirectional Mendelian randomization (MR) in summary-level data for AD (N = 455,258) and summary-level data for seven SRPs (sample size ranges from 359,916 to 1,331,010). AD shared a strong genetic basis with insomnia (r g = 0.20; p = 9.70 × 10–5), snoring (r g = 0.13; p = 2.45 × 10–3), and sleep duration (r g = −0.11; p = 1.18 × 10–3). The CPASSOC identifies 31 independent loci shared between AD and SRPs, including four novel shared loci. Functional analysis and the TWAS showed shared genes were enriched in liver, brain, breast, and heart tissues and highlighted the regulatory roles of immunological disorders, very-low-density lipoprotein particle clearance, triglyceride-rich lipoprotein particle clearance, chylomicron remnant clearance, and positive regulation of T-cell–mediated cytotoxicity pathways. Protein–protein interaction analysis identified three potential drug target genes (APOE, MARK4, and HLA-DRA) that interacted with known FDA-approved drug target genes. The CPASSOC and TWAS demonstrated three regions 11p11.2, 6p22.3, and 16p11.2 may account for the shared basis between AD and sleep duration or snoring. MR showed insomnia had a causal effect on AD (ORIVW = 1.02, P IVW = 6.7 × 10–6), and multivariate MR suggested a potential role of sleep duration and major depression in this association. Our findings provide strong evidence of shared genetics and causation between AD and sleep abnormalities and advance our understanding of the genetic overlap between them. Identifying shared drug targets and molecular pathways can be beneficial for treating AD and sleep disorders more efficiently.
Managers' Perception on the IT Audit Recommendations: The Effect of Risk Significance, Ease of Implementation and Added Value on Implementation of Recommendations

The purpose of this study is to analyse the impact of the risk significance of audit results, the quality of the recommendations given on how easy it is to implement them, and the added benefit to the organization in implementing the recommendations. After a comprehensive literature review, the study provides a statistical analysis through a questionnaire that has been distributed to investigate the effect of Risk Significance, Ease of Implementation, and the Added Value on the implementation of the recommendations within organizations. Regarding the results obtained from the questionnaire, all Cronbach’s Alpha values are within the acceptable level, whereas the first three variables (Implementation of Recommendations, Risk Significance and Ease of Implementation) have a strong positive correlation between each other. There is a weak positive correlation between Added Value of Recommendations with other variables. In the regression analysis was found that all independent variables have a positive effect on the depended variable.

Comparison the Effect of Bromelain Enzyme, Phosphoric Acid, and Polyacrylic Acid Treatment on Microleakage of Composite and Glass Ionomer Restorations

Statement of the Problem: Resin modified glass-ionomer cement (RMGIC) shows low microleakage values. Bromelain enzyme is a deproteinizing agent with an anti-inflammatory effect in human body.Efective cavity treatment is an important factor in reduction of microleakage. Purpose: The aim of this study was to determine the effectiveness of the deproteinizing aspect of 10% bromelain enzyme on the microleakage of RMGIC and composite restorations. Materials and Method: In this experimental study, 40 non-carious extracted human molar teeth were categorized in eight experimental groups (n=5). Standard class V cavities were prepared on the buccal and lingual surfaces of the teeth (n=10). The specimen were classified as Group 1, in which 20% polyacrylic acid (PAA) was applied on the teeth then treated with 10% bromelain enzyme; Group 2: 10% bromelain enzyme was applied; Group 3: 10% bromelain enzyme was applied and then treated with polyacrylic acid; Group 4: 20% polyacrylic acid was applied. Groups1 to 4 were restored with RMGIC (Fuji II LC, GC, Japan). Group 5: etched by 37% phosphoric acid and then treated by 10% bromelain; Group 6: 10% bromelain enzyme was applied without etching; Group 7: teeth were deproteinized with 10% bromelain enzyme and then etched with 37% phosphoric acid; and Group 8: cavities were etched with 37% phosphoric acid. In the groups 5 to 8, Adper single bond (3M, ESPE, USA) and filled with composite resin Z350 (3M, ESPE, USA). After thermocycling, the teeth were sectioned. Microleakage scores were measured using stereomicroscope (40×). Kruskal-Wallis and Mann-Whitney tests were used for data analysis. (p< 0.05) Results: Statistical analysis did not show any significant difference in occlusal and gingival margin microleakage in glass ionomer groups (1-4) (occlusal p= 0.218, gingival p= 0.192). Kruskal-Wallis revealed significant difference in occlusal and gingival margin microleakage of Groups 5 to 8 (occlusal p= 0.006 and gingival p= 0.00). Group 5 demonstrated the lowest occlusal microleakage (occlusal mean=0.00). Conclusion: Applying bromelain or polyacrylic acid did not affect the microleakage of glass ionomer filling. Due to the antinflamatory effects of bromelain, we suggest using it instead of PAA. Pretreatment of 10% bromelain enzyme after phosphoric acid significantly decreased microleakage in the occlusal and gingival margin of composite filling.
Childhood Imaginary Companions and Schizotypy in Adolescents and Adults1

Objective: This study evaluated the association of Childhood Imaginary Companion (CIC) status and schizotypy levels of adolescents and adults within the framework of the Hierarchical Taxonomy of Psychopathology (HiTOP). Method: The sample included 255 Iranian adolescents and adults, grouped according to their CIC status, who responded mostly via e-questionnaires on a website. Schizotypy dimensions were compared between these two groups. Two measures compatible with the HiTOP model were also evaluated both in relation to the short scale of the Oxford-Liverpool Inventory of Feelings and Experiences (sO-LIFE) schizotypy dimensions and the CIC status of participants; one scale used exclusively with adolescents (i.e., the Achenbach System of Empirically-Based Assessment-Youth Self-Report [ASEBA-YSR]), and another with adults (i.e., the NEO-Five Factor Inventory [NEO-FFI]). Results: Scores on the unusual experiences (UnEx) the impulsive nonconformity (ImpNon) dimensions, and the total score of the sO-LIFE were higher for the CIC group. For adolescents, the UnEx dimension and the Thought Problems subscale of the ASEBA-YSR correlated. Scores on three subscales of the ASEBA-YSR (i.e., Thought Problems, Obsessive-Compulsive Problems, and PTSD Problems) were significantly higher for the CIC group. For adults, the neuroticism domain of the NEO-FFI correlated strongly with total score of the sO-LIFE and the cognitive disorganization (CogDis) dimension. This domain of the NEO-FFI was the only one in which CIC adults scored higher than the NIC group. Conclusion: CIC in adolescents and adults is associated with a set of schizotypy dimensions in line with the concept of the “happy schizotype. ”
Value-added Tax, Revenue Generation and Economic Growth in Nigeria

This study investigated the effect of Value-added Tax (VAT) on revenue generation and economic growth in Nigeria. It specifically examined the effect of VAT on Gross Domestic Product (GDP) and the total revenue generated in Nigeria for the period (1994-2018) as well as the trend of VAT in the period under review. Time-series data were employed in the study to run the regression for VAT on total tax revenue and GDP. The vector error correction and autoregression models were used in the regression. VAT, total tax revenue and GDP were included in the data at the end of each year for the period (1994-2018). In other to accommodate the long-run properties of the variables, tests for stationarity and co-integration were carried out. The study finds that VAT has a significant effect on total tax revenue with a two-year lag and it increasingly explains changes in total tax revenue with time. The study also shows that VAT has a significant and negative effect on GDP with a one-year lag. The trend in VAT has a positive coefficient, indicating that VAT increases with time. In view of the findings, the study, therefore, recommends that government should critically evaluate the process of VAT collection, eliminate bureaucratic procedures and improve transparency so that economic units can synchronise their efforts with those of tax authorities.
Finite-size effects of Kirkwood–Buff integrals from molecular simulations

The modelling of thermodynamic properties of liquids from local density ﬂuctuations is relevant to many chemical and biological processes. The Kirkwood–Buﬀ (KB) theory connects the microscopic structure of isotropic liquids with macroscopic properties such as partial derivatives of activity coeﬃcients, partial molar volumes and compressibilities. O riginally, KB integrals were formulated for open and inﬁnite systems which are diﬃcult to access with standard Molecular Dynamics (MD) simulations. Recently, KB integrals for ﬁnite and open systems were formulated (J P hys C hem Lett. 2013;4:235). From the scaling of KB integrals for ﬁnite subvolumes, embedded in larger reservoirs, with the inverse of the size of these subvolumes, estimates for KB integrals in the thermodynamic limit are obtained. Two system size eﬀects are observed in MD simulations: (1) eﬀects due to the size of the simulation box and the size of the ﬁnite subvolume embedded in the simulation box, and (2) eﬀects due to computing radial distribution functions (RDF) from a closed and ﬁnite system. In this study, we investigate the two eﬀects in detail by computing KB integrals using the following methods: (1) Monte C arlo simulations of ﬁnite subvolumes of a liquid with an analytic RDF and (2) MD simulations of a W CA mixture for various simulation box sizes, but at the same thermodynamic state. We investigate the eﬀect of the size of the simulation box and quantify the diﬀerences compared to KB integrals computed in the thermodynamic limit. We demonstrate that calculations of KB integrals should not be extended beyond half the size of the simulation box. For ﬁnite-size eﬀects related to the RDF, we ﬁnd that the Van der Vegt correction (J C hem Theory C omput. 2013;9:1347) yields the most accurate results.
Knowledge Management Leaders' Top Issues

Knowledge leaders are hired by organizations to create and maintain knowledge management (KM) environments supported by various technologies, which bring their potential of difficulties and technological issues. However, these individuals’ perceptions of KM top issues appear to be imprecise and ambiguous when referring to the literature. As the need for organizations to manage and extract knowledge increases, so does the demand for identifying KM leaders’ top issues that they deal with on a regular basis. AbstRAct
Parameter design and optimization for mobile mechanism of a transformable wheel-track robot

According to the terrain features of the irregular environment, we propose a novel mobile mechanism of the transformable wheel-track robot (TWTR). The TWTR can adapt autonomously to the irregular environment by transforming the track configuration or by changing the locomotion mode between track mode and wheel mode. The TWTR mechanism consists of a control system unit and two symmetric transformable wheel-track units. As the mobile mechanism of TWTR, the wheel-track unit is composed of a transformable track mechanism and a drive wheel mechanism. The drive system of the wheel-track unit provides two outputs in different form only by one servo motor, or rather enables the wheel-track unit to have the abilities to transform the configuration of the track and to make the robot move by wheel or by track. In this paper, we design the parameters of track mechanism by parametric optimization based on genetic algorithm, and design the parameters of the drive wheel mechanism according to the configuration features of the wheel-track unit. The validity of the parameters is demonstrated by simulation on the robot transforming the track configuration and changing the locomotion mode.

Purpose – The purpose of this paper is to analyze the effects of both managerial commitment and the professional development of human resources on the benefits obtained from Kaizen implementation at the planning stage in Mexican maquiladora companies. Design/methodology/approach – As part of the methodology, a questionnaire is validated and administered to 423 workers in different companies from the states of Tabasco, Baja California, Sinaloa and Chihuahua. Moreover, a structural equation model is proposed to relate four latent variables: two concerning managerial commitment and the professional development of human resources, and two more related to the kinds of benefits obtained (economic and for human resources). Findings – Results demonstrate that managerial commitment has a direct and positive impact on economic benefits and those for human resources. The major contribution of this study is, however, the determination of dependency measures between these variables. Practical implications – This resea.
Hamburg Wheel-Track Test Equipment Requirements and Improvements to AASHTO T 324

In this study, a comprehensive experimental program was conducted to evaluate the capability of five commercially available Hamburg Wheel Tracking (HWT) equipment as well as their ability to accurately measure, control, and maintain the desired test conditions as specified in AASHTO T 324. Based on the results of this study, researchers were tasked to provide proposed revisions with commentary to AASHTO T 324 to enable the use of a performance type specification for Hamburg test equipment. Modifications are proposed to address equipment capabilities, components, or design feature in order to ensure proper testing and accurate, reproducible results. Proposed modifications are discussed in this report to ensure repeatable measurements and that the results from different manufacturers are comparable. These modifications include change to temperature measurement and range, impression measurement system, data collection, and data analysis and reporting. In addition to the proposed modifications to the AASHTO T 324 specifications, the vendors may need to modify their equipment to meet the new specification requirements.
Local dynamics during thinning and rupture of liquid sheets of power-law fluids

Abstract Rupture of liquid sheets of power-law fluids surrounded by a gas is analysed under the competing influences of pressure due to van der Waals attraction, inertia, viscous stress and capillary pressure due to surface tension. Results of a combined theoretical and computational study are presented over the entire range of parameters governing the thinning of a power-law fluid of power-law exponent $0 < n \le 1$ ($n=1$: Newtonian fluid) and Ohnesorge number $0 \le Oh < \infty$, where $Oh \equiv \mu _0/\sqrt {\rho h_0 \sigma }$, and $\mu _0, \rho, h_0$ and $\sigma$ stand for the zero-deformation-rate viscosity, density, the initial sheet half-thickness and surface tension, respectively. The dynamics in the vicinity of the space–time singularity where the sheet ruptures is asymptotically self-similar, and thus the variation with time remaining until rupture $\tau \equiv t_R - t$, where $t_R$ is the time instant $t$ at which the sheet ruptures, of sheet half-thickness, lateral length scale and lateral velocity is determined analytically and confirmed by simulations. For sheets for which inertia is negligible ($Oh^{-1}=0$), two distinct viscous scaling regimes are found, one for $0.58 < n \le 1$ and the other for $n \le 0.58$. The thinning dynamics of inviscid sheets ($Oh = 0$) is identical to that of Newtonian ones. For real fluids for which neither viscosity nor inertia is negligible, it is shown that the aforementioned creeping and inertial flow regimes are transitory and the thinning of power-law sheets exhibits a remarkably richer set of scaling transitions compared with Newtonian sheets.

Simplified-robust geotechnical design of soldier pile–anchor tieback shoring system for deep excavation

ABSTRACT The shoring system that consists of soldier piles and anchor tiebacks is often used in deep excavations in sandy deposits. However, uncertainties often exist in the design of such shoring systems. In this article, a simplified-robust geotechnical design method is proposed to account for these uncertainties in the shoring system design. Specifically, for a given deep excavation, uncertain soil parameters and surcharges are treated as noise factors, and the parameters of soldier piles and tieback anchors are treated as design parameters. Robust design is then implemented as a multiobjective optimization problem, in which the design robustness is sought along with cost efficiency and safety requirements. A trade-off between design robustness and cost efficiency exists and the optimization usually leads to a Pareto front. By applying the knee point concept, the most preferred design that meets the safety requirements and yields the best compromise between design robustness and cost efficiency can be identified on the Pareto front. Improvements made to the existing robust geotechnical design method include an efficient formulation of the design robustness and a new procedure for finding the most preferred design in the design pool. The new simplified-robust geotechnical design method is illustrated with a real-world excavation case study.
Long-wavelength equations of motion for thin double vorticity layers

Abstract We consider the time evolution in two spatial dimensions of a double vorticity layer consisting of two contiguous, infinite material fluid strips, each with uniform but generally differing vorticity, embedded in an otherwise infinite, irrotational, inviscid incompressible fluid. The potential application is to the wake dynamics formed by two boundary layers separating from a splitter plate. A thin-layer approximation is constructed where each layer thickness, measured normal to the common centre curve, is small in comparison with the local radius of curvature of the centre curve. The three-curve equations of contour dynamics that fully describe the double-layer dynamics are expanded in the small thickness parameter. At leading order, closed nonlinear initial-value evolution equations are obtained that describe the motion of the centre curve together with the time and spatial variation of each layer thickness. In the special case where the layer vorticities are equal, these equations reduce to the single-layer equation of Moore (Stud. Appl. Math., vol. 58, 1978, pp. 119–140). Analysis of the linear stability of the first-order equations to small-amplitude perturbations shows Kelvin–Helmholtz instability when the far-field fluid velocities on either side of the double layer are unequal. Equal velocities define a circulation-free double vorticity layer, for which solution of the initial-value problem using the Laplace transform reveals a double pole in transform space leading to linear algebraic growth in general, but there is a class of interesting initial conditions with no linear growth. This is shown to agree with the long-wavelength limit of the full linearized, three-curve stability equations.
