“Put God above All [and He] Will Glorify Your Marriage.” Relational Spirituality in Black Couples

Abstract This study examines the influence of religion on relational spirituality among 33 Black married couples (N = 66). Previous research has largely relied on samples of White middle-class Americans to assess aspects of relational spirituality within marriages. In contrast, this study uses in-depth qualitative interviews from socioeconomically diverse Black married couples to determine how religion informs perceptions of relational spirituality among an underexamined population. Findings show that Black married couples employ mechanisms of relational spirituality in several ways. Specifically, Black married couples utilize relational spirituality for maintaining and transforming their marriage through: (a) Putting God First; (b) Studying and Applying the Word of God; and (c) Giving Their Life Over to God. Implications of findings from this study suggest that relational spirituality may foster increased marital satisfaction, quality, and commitment, thereby serving as a potential buffer against divorce for Black couples. Implications and recommendations for future research are also discussed.
Monitoring the impacts of tourism-based social media, risk perception and fear on tourist’s attitude and revisiting behaviour in the wake of COVID-19 pandemic

ABSTRACT This research aims to explore the impact of perceived risk, fear and social media on tourist’s attitude, engagement, and revisit intention in COVID-19 pandemic situation. The results of PLS-SEM indicate that fear of COVID-19 and perceived risk has a significant negative impact on attitude towards travelling. Similarly, findings show that perceived risk has a significant negative effect, and social media has a significant positive effect on customer brand engagement during COVID-19 outbreak. Results also reveal that customer engagement and attitude have positive effects on both brand co-creation and revisit intention. The insights acquired from this research offers a mechanism behind fear/perceived risk and social media-based brand engagement, attitude, co-creation and revisit intention in pandemic situation and implications for tourism-reliant destinations to build recovery-strategies/tactics in coping with the impact of pandemics to re-store tourism.

Numerical Study on the Tandem Submerged Hydrofoils Using RANS Solver

This paper is presented on the tandem two-dimensional hydrofoils with profiles NACA4412 in single-phase and two-phase flow domains for different submergence depths and different distances in a various angle of attack (AoA). Also, supercavitation is studied at by the Zwart cavitation model. Reynolds-averaged NavierâStokes (RANS) with the shear stress transport (SST) K-I is employed as a turbulence model in transient analysis of Ansys FLUENT software. The numerical results show that, by increasing depth, the drag coefficient increases for both hydrofoils 1 and 2 as well as the lift coefficient. The drag coefficient of hydrofoil 2 is bigger than hydrofoil 1 for all depths; moreover, it was found that the flow pressure behind the hydrofoil 1 had affected the upper and the lower surface of the hydrofoil 2 at each distance or AoA. These effects are observed in the hydrofoil 2 lift coefficient as well as the flow separation. However, the maximum lift-to-drag ratio is observed at AoAâ=â and 3.5c distance. Also, single-phase results reveal that the value of pressure and the hydrodynamic coefficient are very different from the two-phase flow results, due to the elimination of the free surface. So, a two-phase flow domain is recommended for increasing the accuracy of results. In addition, the investigation of supercavitation shows a growth in cavity occurrence on the surface by raising AoA.
Light-Emitting Diodes (LED): A Promising Street Light System to Reduce the Attraction to Light of Insects

Currently, there is a demand for more energy-efficient lighting sources, however, light emitted by different lighting systems differs in primary properties such as intensity, propagation direction, and wavelength spectrum, among others, and these properties may affect insect light attraction. Despite the energetic benefits of light-emitting diodes (LED) as street light systems, their ecological impacts on insects have not yet been tested on a wide range of taxa. Using an experimental approach, we showed that LED street lights lead to a reduction in the total number of insects captured with light traps in a wide range of families. Coleoptera and Lepidoptera orders were the most sensitive groups to ecological light pollution in the study area. We suggest that LED was the least attractive light system for most of the affected groups both because of its very little emitted short-wavelength light and because of its lower light intensity. We expect that the more and more widespread use of LED lights as a measure to reduce economic costs of outdoor lighting should lead to a lower attraction to street lights in most of the affected insect taxa and to diminish the negative impacts of artificial light attraction on the ecosystems.
Machinability analysis of delamination and thrust force in drilling of pure and added GFRP composites

The effects of cutting parameters on the thrust force and delamination factor in the drilling of pure, Al2O3, and SiO2 added GFRP/epoxy composites were investigated. Experimental studies were performed to investigate thrust force and delamination factor. Taguchi experimental design and response surface methodology were employed to establish parametric relationships between the experimental parameters and the machinability outputs consisting of delamination and thrust force. When examining the effect of cutting speed and feed on thrust forces and delamination factors for the three materials, the smallest values of the cutting parameters for all three materials gave the minimum thrust forces and delamination factors. Machinability Index is also proposed. According to the machinability index, under the effect of delamination and thrust force parameters, it was seen that pure epoxy composite material has better machinability than the other composite materials. It has been found that the effect of feed rate on delamination is greater than the cutting speed, and the cutting speed has a low effect.
Stability, Scalability, Speedability, and String Stability of Connected Vehicle Systems

This article considers the third-order connected vehicle systems (CVSs) to implement cooperative formation control for autonomous vehicles. The error dynamics is modeled based on the proposed distributed control protocols for two large classes of general network topologies. The performance indices, such as stability, scalability, speedability, and string stability (4S) indices, are investigated. The necessary and sufficient conditions of stability for CVSs are derived and properties of characteristic roots are discussed. These roots are dependent on information of the given network topology. The sufficient conditions of stability, which are independent of network topology, are given by analyzing the range of eigenvalues of the Laplacian matrix of the corresponding network topology, so scalability is guaranteed. To guarantee fast convergence speed, the upper boundary of stability margin is derived, which is also independent of the size of the network topology and can be conveniently tuned by the controller gains and model parameter. The necessary and sufficient conditions of stability are also achieved for the bidirectional-leader following (BLF) network topology. The conditions of string stability are further derived to ensure that spacing errors (caused by disturbances) decay along the vehicle platoon. Furthermore, combining the conditions of stability, speedability, and string stability, the CVSs are proven to be not only stable but also string stable and quickly convergent. Thus, the 4S indices can be guaranteed. Numerical simulations are provided to validate the theoretical results.
Investigating relationship between fluid and crystallised intelligence and vocabulary size in students learning French as a foreign language

In this study, the relationship between fluid and crystallised intelligence and vocabulary size was investigated among Iranian students learning French as a foreign language. Studies emphasised on the importance of vocabulary size and language comprehension and tried to discover mental and intelligence factors related to this issue. To administer the present quantitative study, the Persian Adaptation of Baddeley’s (1968) Grammatical reasoning Test for Fluid Intelligence, Persian Test of Baghaei & Tabatabaee (2015) for Crystallised intelligence, and Nation’s (2012) Test of Vocabulary Size were instrumented. Population of the study was 100 intermediate learners of French language from three branches of Safir institute in Tehran. Data was analysed using SPSS and correlational tools to specify the variables correlation. Result showed that there is a significant relationship between crystallised intelligence and size of vocabulary (p 0.5). It was concluded that fluid intelligence does not predict learners’ vocabulary size, but crystallised intelligence as grows gradually determines learners’ vocabulary size.
Identifying Climate Change Adaptation Efforts in the Batutegi Forest Management Unit, Indonesia

The Batutegi Forest Management Unit (FMU) in Lampung Province, Indonesia is beginning to observe the consequences of climate change. Meanwhile, communities in Batutegi are also suggesting that effects of climate change are becoming more prominent in their region. Indicators include rising air temperature and the increasing regularity of extreme weather changes. Studies show that land cover has decreased by up to 95% in the region. As these trends intensify, predictions note that the Batutegi reservoir and the productivity of the surrounding protected forests will be affected. This research examines FMU efforts to adapt to vulnerabilities from environmental and climate change. The broader objective of this research is to determine the appropriate climate change adaptation efforts, specifically regarding the management of sustainable forest protection. The method is conducted through regression analysis to identify significant variables and applies the Analytic Hierarchy Process (AHP) to identify priorities for planned interventions for climate change adaptation by the FMU. Based on regression results there were four significant variables, i.e. appropriate agroforestry initiatives, non-timber forest products, community institutional support, and local policy engagement. This research also considers various kinds of technologies of adaptation applied by local communities. Examining community efforts also presents possibilities for improving FMU institutional planning that is locally responsive. This is done primarily through agroforestry techniques and other community conservation practices. Based on the result of the AHP analysis, the findings highlight various programs related to agroforestry technologies as the top priority. Thereafter, priorities point to institutional development policies. Together, these priorities can form the basic considerations for developing climate change adaptation policies in Batutegi. These policies can be applied with, and by communities in managing forests through agroforestry, beginning with support for high quality seed procurement that also supports all phases of cultivation and supply chain through final product marketing. As a result, forest productivity and support for local income can form a robust approach for fulfilling community needs despite the effects of environmental and climate change in Batutegi.
READING SKILLS AND PRIOR KNOWLEDGE IN THE COMPREHENSION OF CAUSAL RELATIONS: MULTIPLE INTERACTIONS BETWEEN FORMAL SCHOOLING, TYPE OF INFORMATION AND COHESION MARKERS

The main objective of this paper is to analyze the interactions between reading skills, readers’ prior knowledge and the linguistic characteristics of texts, specifically during the comprehension of causal relations in Spanish. Within this framework, we also attempt to provide psycholinguistic evidence that will help us understand text-based learning processes. We present two psycholinguistic experiments to analyze the link between prior knowledge and readers’ formal schooling level with text variables, such as absence/ presence of connectives and the structure of causal relations during the text comprehension process. This gives us the possibility to simultaneously analyze several interactions. We evaluated response time, reading time, and accuracy in the responses. Our results show that not involving prior knowledge changes causal relations comprehension patterns, but also that in these cases, the presence of connectives not only facilitates the comprehension process but rather is a condition to make it possible. We also discuss the need to differentiate general reading skills from the area of expertise that the subjects may have, since these variables connect in specific ways with the different text types. In order to boost text-based learning processes it is necessary to display a clear range of conclusions referring to these multiple interactions.
Ischiofemoral impingement: the evolutionary cost of pelvic obstetric adaptation

Abstract The risk for ischiofemoral impingement has been mainly related to a reduced ischiofemoral distance and morphological variance of the femur. From an evolutionary perspective, however, there are strong arguments that the condition may also be related to sexual dimorphism of the pelvis. We, therefore, investigated the impact of gender-specific differences in anatomy of the ischiofemoral space on the ischiofemoral clearance, during static and dynamic conditions. A random sampling Monte-Carlo experiment was performed to investigate ischiofemoral clearance during stance and gait in a large (n = 40 000) virtual study population, while using gender-specific kinematics. Subsequently, a validated gender-specific geometric morphometric analysis of the hip was performed and correlations between overall hip morphology (statistical shape analysis) and standard discrete measures (conventional metric approach) with the ischiofemoral distance were evaluated. The available ischiofemoral space is indeed highly sexually dimorphic and related primarily to differences in the pelvic anatomy. The mean ischiofemoral distance was 22.2 ± 4.3 mm in the females and 29.1 ± 4.1 mm in the males and this difference was statistically significant (P < 0.001). Additionally, the ischiofemoral distance was observed to be a dynamic measure, and smallest during femoral extension, and this in turn explains the clinical sign of pain in extension during long stride walking. In conclusion, the presence of a reduced ischiofemroal distance and related risk to develop a clinical syndrome of ischiofemoral impingement is strongly dominated by evolutionary effects in sexual dimorphism of the pelvis. This should be considered when female patients present with posterior thigh/buttock pain, particularly if worsened by extension. Controlled laboratory study.
Robust Sensorless Model-Predictive Torque Flux Control for High-Performance Induction Motor Drives

This paper introduces a novel sensorless model-predictive torque-flux control (MPTFC) for two-level inverter-fed induction motor (IM) drives to overcome the high torque ripples issue, which is evidently presented in model-predictive torque control (MPTC). The suggested control approach will be based on a novel modification for the adaptive full-order-observer (AFOO). Moreover, the motor is modeled considering core losses and a compensation term of core loss applied to the suggested observer. In order to mitigate the machine losses, particularly at low speed and light load operations, the loss minimization criterion (LMC) is suggested. A comprehensive comparative analysis between the performance of IM drive under conventional MPTC, and those of the proposed MPTFC approaches (without and with consideration of the LMC) has been carried out to confirm the efficiency of the proposed MPTFC drive. Based on MATLAB® and Simulink® from MathWorks® (2018a, Natick, MA 01760-2098 USA) simulation results, the suggested sensorless system can operate at very low speeds and has the better dynamic and steady-state performance. Moreover, a comparison in detail of MPTC and the proposed MPTFC techniques regarding torque, current, and fluxes ripples is performed. The stability of the modified adaptive closed-loop observer for speed, flux and parameters estimation methodology is proven for a wide range of speeds via Lyapunov’s theorem.
BMI, waist to height ratio and waist circumference as a screening tool for hypertension in hospital outpatients: a cross-sectional, non-inferiority study

Objective This non-inferiority study aimed to determine the burden of obesity in a hospital outpatient setting of a developing country, using three commonly employed metrics as predictors of hypertension (HTN). Design A cross-sectional study design was adopted. Setting This study was conducted in Health Promotion and Risk Factor Screening Services of a tertiary hospital for eye and ear, nose, throat in a semiurban area of Nepal. Participants 2256 randomly selected outpatients between 40 and 69 years old. Outcome measures The three obesity metrics and HTN were analysed for association using correlation, the area under the receiver operating characteristic (ROC) curve and ORs. Results The prevalence of obesity or overweight by body mass index (BMI) was 58.29%; by waist-to-height ratio (WHtR) was 85.95%, high waist circumference (WC) was observed among 66.76% of participants. Female participants had a greater prevalence of high WC (77.46%) than males (53.73%) (p<0.001). Prevalence of HTN and pre-HTN were 40.67% and 36.77%, respectively. The areas under the ROC curve were significantly higher than 0.5 for BMI (0.593), WHtR (0.602) and WC (0.610). Conclusion This study showed that WHtR and WC measured were not inferior to BMI as a metric for obesity detection and HTN prediction. Because of its low cost, simplicity of measurement and better ability to predict HTN, it may become a more usable metric in health facilities of low-income and middle-income countries.
WiGRUNT: WiFi-Enabled Gesture Recognition Using Dual-Attention Network

Gestures constitute an important form of nonverbal communication where bodily actions are used for delivering messages alone or in parallel with spoken words. Recently, there exists an emerging trend of WiFi sensing-enabled gesture recognition due to its inherent merits like remote sensing, non-line-of-sight covering, and privacy-friendly. However, current WiFi-based approaches mainly reply on domain-specific training since they don’t know “where to look” and “when to look. ” To this end, we propose WiGRUNT, a WiFi-enabled gesture recognition system using dual-attention network, to mimic how a keen human being intercepting a gesture regardless of the environment variations. The key insight is to train the network to dynamically focus on the domain-independent features of a gesture on the WiFi channel state information via a spatial-temporal dual-attention mechanism. WiGRUNT roots in a deep residual network (ResNet) backbone to evaluate the importance of spatial-temporal clues and exploit their inbuilt sequential correlations for fine-grained gesture recognition. We evaluate WiGRUNT on the open Widar3 dataset and show that it significantly outperforms its state-of-the-art rivals by achieving the best-ever performance in-domain or cross-domain.

The Effects of Convenience and Risk on E-Loyalty through the Mediating Role of E-Service Quality: A Comparison for China and Turkey

Abstract This study aims to examine the direct and indirect effects of perceived shopping convenience, e-service quality, and perceived risk on loyalty in an online shopping context. The study compares Turkey and China that have different market characteristics. Perceived online shopping convenience and perceived risk were measured as multi-dimensional constructs. Multi-group path analysis indicated that the indirect effect of perceived online shopping convenience dimensions on loyalty through e-service quality differs across Turkish and Chinese samples. The dimensions of perceived risk have insignificant effects on e-loyalty. The results also showed how the negative impact of e-service quality on perceived risk dimensions varies across countries. In general, the study showed a cross-cultural variation in the evaluation of online shopping convenience, risk, and service quality.
