Understanding the Facebook Users' Behavior towards COVID-19 Information Sharing by Integrating the Theory of Planned Behavior and Gratifications

This study aimed to investigate Facebook users’ information sharing behavior during COVID-19 by merging the theory of planned behavior and uses and gratifications theory into one theoretical framework. Facebook has been playing a pivotal role in shaping how people across the globe are experiencing the coronavirus pandemic. Yet knowledge about motivational and behavioral factors influencing information sharing through Facebook remains limited in the context of COVID-19. We collected data from 540 Facebook users through Google Forms. Structural equation modeling was applied to test the hypotheses of the study. We noted that Facebook users shared COVID-19 information for entertainment, socializing, and status-seeking. The findings further identified that attitude toward behavior, subjective norms, and perceived behavioral control positively affect the behavioral intention and actual behavior of Facebook users to share COVID-19 information.
Orientation control of a differential mobile robot through wheel synchronization

This paper presents the orientation control of a differential mobile robot through the synchronization of the motions of two driving wheels, using an adaptive coupling control algorithm. The orientation error is usually caused by the synchronization error between two driving wheels and has the largest impact on the motion accuracy. The proposed controller incorporates the cross-coupling technology into an adaptive control architecture and guarantees asymptotic convergence to zero of the position tracking errors of two wheels as well as the synchronization error between them. Experiments demonstrate that the proposed control method exhibits better motion performance than traditional control methods especially in the orientation control.

The Relations between Parental Active Mediation, Parent-Child Relationships and Children’s Problematic Mobile Phone Use: a Longitudinal Study

ABSTRACT This longitudinal study examined the reciprocal relationship between parental active mediation, parent-child relationships, and children’s problematic mobile phone use (PMPU). A sample of 258 primary school students in Beijing, China, completed self-report questionnaires at three time points, with a one-semester interval (a six-month gap) between each measurement wave. The cross-lagged model test results revealed that parental active mediation may help reduce children’s PMPU, whereas the corresponding reverse path from PMPU to parental active mediation was nonsignificant. There was a reciprocal negative relationship between parent-child relationships and children’s PMPU. Parental active mediation had a positive effect on parent-child relationships, yet the corresponding reverse path from parent-child relationships to parental active mediation was nonsignificant. Overall, this study described a dynamic picture of children’s PMPU, suggesting both a parent-driven process and a child-driven process in the prediction of children’s PMPU. Our findings provide theoretical and practical implications to prevent or reduce children’s engagement in PMPU.
Board Characteristics and Sustainability Reporting of Listed Non-Financial Firms in Nigeria

The hazardous effects of companies’ activities have sparked the increasing need from stakeholders for transparent and trustworthy report on sustainability issues. There is still evidence of low report on sustainability performance in the listed non-financial firms in Nigeria which has attributed to corporate governance mechanism issues. Therefore, this study examines the effect of board characteristics on sustainability reporting of listed non-financial firms in Nigeria from 2010 to 2018. Sustainability reporting was measured using content analyses on corporate annual report on sustainability used Global Reporting Initiatives (G4) guidelines. The population of the study consist of 47 non-financial firms from Consumer goods, Industrial and Oil and Gas sectors. The study used a sample of 30 firms and secondary data which was employed, sourced from the audited annual report of the sampled firms was employed. Robust Fixed effect regression was used for the analysis and the study found among others that board gender has positive and significant effect on sustainability reporting of listed non-financial firms in Nigeria. The study concludes that women directors enhance the level of reporting on sustainability reporting of listed non-financial firms in Nigeria. The study recommendation among others that board of directors should ensure diversity gender by appointing more women directors on the board as the mean also reveal that their presence is low.
Solution strategy for non‐linear finite element analyses of large reinforced concrete structures

When performing non‐linear finite element analyses during the design of large reinforced concrete structures, there is a need for a general, robust and stable solution strategy with a low modelling uncertainty which comprises choices regarding force equilibrium, kinematic compatibility and constitutive relations. In this paper, analyses of experiments with a range of structural forms, loading conditions, failure modes and concrete strengths show that an engineering solution strategy is able to produce results with good accuracy and low modelling uncertainty. The advice is to shift the attention from a detailed description of the post‐cracking behaviour of concrete to a rational description of the pre‐cracking compressive behaviour for cases where large elements are used and the ultimate limit capacity is sought.
Engagement, motivation, and working performance

This study aims to examine and analyze the effect of employee engagement and motivation on working performance. This population is 618 employees working at one of the textile companies in Bandung, distributed into seven divisions. The number of samples of 247, furthermore, is counted by the Isaac and Michael formula. Because of the divisions, the pieces are taken by a stratified random sampling technique. Ominously, not all of them are responsive. Hence, this research can get a 54.66% participating level on the online survey or successfully collect 135 responses. Besides, this study utilizes the confirmatory factor analysis and the composite reliability coefficient analysis to test data quality. After that, the structural equation model based on variance is used. After examining the proposed hypothesis and discussing the related facts, this study deduces that a positive effect of employee engagement and motivation on working performance exists.
Three-Dimensional Placement and Transmit Power Design for UAV Covert Communications

This work tackles the joint optimization of a unmanned aerial vehicle's (UAV's) three-dimensional (3D) placement and transmit power for covert communications with the objective to maximize the communication covertness subject to a constraint on communication quality. We analytically prove that the optimal horizontal location of the UAV must be on the straight line connecting the legitimate receiver and the warden, while its optimal height is the minimum allowable flying altitude. Subsequently, we derive closed-form expressions to characterize the UAV's optimal 3D location and its optimal transmit power, taking into account the impact of finite blocklength coding. Our numerical results show that the developed optimal design can achieve a better covertness performance compared with an optimal two-dimensional (2D) UAV deployment, especially when the warden is close to the receiver. Besides, we show that, for a given requirement on the communication quality, communication covertness does not always improve as the number of channel uses increases.
Planting Density X Mineral Nutrient Interaction Effect on Biomass Production and Partitioning of Arabica Coffee Cultivars

Biomass partitioning is important process for energy distribution among their leaves, stem and roots. The study was designed to evaluate the effect of population densities and fertilizer rates on biomass production and partitioning of Arabica coffee cultivars under nursery conditions. It was conducted at Jimma Agricultural Research Center from (February 29 to October 29), 2018 season. The treatments were arranged by using completely randomized design and a factorial experiment with three replications. Treatments consisted of combinations of two Arabica coffee cultivars (74110 and 75227), four population densities (one, two, three and four plants per polythene tube) and three compound NPK (22:6:12 + Te) rates (control, 5g and 10g). The results showed that, interaction effect of coffee genotypes, population densities and fertilizer rates was highly significant (P ≤ 0.01) for SFW, TFW and TDW, whereas significant (P ≤ 0.05) for RFW, LFW, ShFW, RDW, SDW, LDW and ShDW. The result revealed that, the maximum values of fresh weight (RFW, SFW, LFW, ShFW and TFW) and dry weight (RDW, SDW, LDW, ShDW and TDW) were obtained from treatment combinations of 74110*PD2*5g of NPK and 75227*PD1*5g of NPK in cultivar-74110 and cultivar-75227, respectively. Similarly, maximum biomass partitioning was observed from leaf dry weight as compared stem and root dry weight which were treated with 5g of NPK for both cultivars. Biomass partitioning optimization is very important to minimize the stress imposed by the limiting resource and more attention should be given on a biotic and biotic factor which affects biomass partitioning under field conditions.
The Critical Height of a Liquid Being Drained from the Tank with Bell-Mouth Drain Port

Vortexing occurs during draining of liquid from tanks. We studied the critical height of a liquid being drained from tank, that is, the liquid height at the moment when the air-core vortex reaches to the drain port. We firstly performed some experiments for determining the critical height, and then based upon the information obtained from the experiments; a simple analytical expression was derived to predict the critical height. The experimental results show that the vortex suppressor, which is suggested in the present paper, could effectively reduce the strength of vortex and consequently reduce the critical height. The results also show that the new analytical expression can predict the critical height with less than 20% error when vortex suppressor is used. To the best of our knowledge, draining from tanks with bell-mouth drain ports has not been paid attention to by other authors.
New drugs registered in Brazil from 2003 to 2013: analysis from the perspective of child health

This study aims to analyze the new drugs registered in Brazil from 2003 to 2013 from the perspective of childcare needs, drug safety and considering the disease burden of the country. This is a retrospective cohort study including new drugs registered in Brazil between 2003 and 2013. Drug indications were related to the Disability-Adjusted Life Year (DALY) of the 2015 Global Burden of Disease Study. Association between the number of new drugs and DALY was determined by Spearman’s coefficient. Post-marketing safety alerts specific to the pediatric population have been identified in the WHO Drug Information Bulletin and on websites of drug regulatory agencies. A total of 134 new drugs were included in the cohort and 46 (34.3%) had a pediatric indication. There was no evidence of an association between the disease burden in children in Brazil and the number of pediatric drugs. The safety alert data associated with the pediatric population published after registration of the new drugs were scarce. The number of new drugs launched in Brazil with a pediatric indication was small, reflecting the international challenges of developing effective and safe medicines for children. No association was found between the number of new drugs and the disease burden.
Exploring the Role of Perceived Organizational Justice and Organizational Commitment as Predictors of Job Satisfaction among Employees in the Hospitality Industry

ABSTRACT The critical role of employees in the hospitality industry is unimpeachable and human resource needs more attention because their satisfactions have a strong influence on the service quality and customers loyalty. In this study, we examined the impact of organizational justice (distributive, procedural, and interactional) and employees’ organizational commitment (affective, continuance, and normative) on the employees’ job satisfaction. A total of 119 questionnaires were gathered from employees in one to five-star hotels in Tehran. The results show that among organizational justice dimensions, only distributive justice has a strong relationship with job satisfaction. Similarly, between employees’ organizational commitment dimensions, only normative commitment has a meaningful impact on the employees’ job satisfaction. However, dissimilar to the previous studies, our investigations did not find any direct relationships between procedural and interactional justice, and affective and continuance commitment with employees’ job satisfaction. Managerial and theoretical implications and directions for future research are discussed.

The phase probability distribution of general Clarke model and its application in Doppler shift estimator

The phase probability density function (PDF) of the channel coefficients is analyzed for general Clarke channel model, and the close-form expressions are obtained under the von Mises/Tikhonov distribution. Then the simplified expressions for Rayleigh and Rice channels are derived. In addition, these expressions are applied to analyze the bias of a Doppler shift estimator based on phase difference proposed firstly by Sheng. The theoretic and simulation results show the good performance and consistency of this estimator.
Fungal Detection in Wheat Using Near-Infrared Hyperspectral Imaging

Different species of fungi infect grain in the field and storage facilities. Contamination by fungi in grain is detected and quantified by traditional methods, such as microbial incubation and microscopic detection, which are subjective, labor intensive, and time consuming. An accurate and timely detection technique for fungal growth in grain is needed to prevent grain from spoiling and to reduce quality loss. In this study, the potential of near-infrared hyperspectral imaging to detect fungal infection in wheat was investigated. Wheat kernels infected with storage fungi, namely Penicillium spp. , Aspergillus glaucus, and Aspergillus niger, were scanned using a hyperspectral imaging system, and a total of 20 image slices at evenly spaced wavelengths between 1000 to 1600 nm were acquired to form a hypercube. A multivariate image analysis (MIA) technique based on principal component analysis (PCA) was used to reduce the dimensionality of the image hypercubes. Two-class and four-class classification models were developed by applying k-means clustering and discriminant (linear, quadratic, and Mahalanobis) analyses. Two-class discriminant classification models gave maximum classification accuracy of 100%, and on average 97.8% infected kernels were correctly classified by the linear discriminant classifier. The four-class linear discriminant classifier correctly classified more than 95% of the kernels infected with Penicillium and 91.7% healthy kernels. However, the discriminant classifiers misclassified the kernels infected with A. niger and A. glaucus.
Effect of genotypes of oil palm as indicator for speed of callus and embryogenic callus formation

oC for 3 months. The results revealed that the highest percentage of callus formation (33.33) was obtained from cross number 7 and percentage of embryogenic callus formation (18) was obtained from cross number 14. The highest number of embryogenic callus formation per explant (15.795) was obtained from cross number 16 after 3 months of culture. Callus initiated from these embryos within 4-5 weeks and classified into 4 types; compact, friable, nodular and root-like structure. The highest increment in callus size (1.17 cm) was obtained from cross number 16. In case of the speed index of callus and embryogenic callus formation, cross 16 gave the highest of both parameters at 35.5 and 20.17, respectively.
Effects of Neglecting PCM Hysteresis While Making Simulation Calculations of a Building Located in Polish Climatic Conditions

The use of phase change materials (PCM) in different building applications is a hot topic in today’s research and development activities. Numerous experimental tests confirmed that the hysteresis of the phase change process has a noticeable effect on heat accumulation in PCM. The authors are trying to answer the question of whether the neglecting of hysteresis or the impact of the speed of phase transformation processes reduce the accuracy of the simulation. The analysis was performed for a model building, created to validate the energy calculations. It was also important to conduct simulations for the polish climatic conditions. The calculations were conducted for three variants of materials. In addition, in the case of models containing layers with PCM, calculations were made both taking into account, as well as excluding material hysteresis in the calculations. In the analyzed examples, after taking into account hysteresis in the calculations, the period of time when surface temperature is below the phase change temperature of the materials decreased by 10.6% and 29.4% between 01 June to 30 September, for the options with PCM boards and Dupont boards, respectively. Significant differences in surface temperature were also observed. The effects of neglecting, even relatively small hysteresis, in the calculations are noticeable and can lead to significant errors in the calculation.
Ultra low noise, PC-based measurement system for the characterization of the metallizations of integrated circuits

Low frequency noise measurements have been successfully used in research laboratories for the characterization of electromigration in interconnection lines of integrated circuits. In this paper an ultra-low noise system capable of performing such measurements contemporaneously on a statistically significant number of samples is described. The system, designed with the aim to make advantageous the utilization of the technique also in industrial environment, is controlled by a personal computer and makes available up to 255 independent input channels for noise measurements. A purposely designed ultra-low noise preamplifier and the use of an optical link between the PC and the low noise section, has allowed to obtain a total background noise which is some orders of magnitude lower than that of preexistent instrumentation.
Arab women’s veiled affordances on Instagram: a feminist semiotic inquiry

ABSTRACT Feminist semiotics is developed to explore Arab women’s self-presentations on Instagram. The novel framework enables interpretive theorising of a corpus Instagram posts by Arab women in the Middle East and North African region (MENA). Qualitative analysis zooms in on the accounts of four Arab women influencers, defined as microcelebrities monetising content online. Self-presentations are theorised as a process of semiosis, which involves signs, objects and interpretants of visual meanings. This perspective is contextual rather than universalising and addresses the lack of theoretical perspectives for considering Arab women’s palette of self-presentations. Simultaneously, the study is reflexive of tensions surrounding feminist semioticians’ positionalities. Unique theorising reveals situated micro-practices and ‘veiled affordances’ of modest while sometimes highly politicised self-presentations by Arab women.
Assessment of Quality for Middle Level and High School Student‐Generated Water Quality Data

Student scientists have analyzed groundwater used for drinking water in rural areas to understand groundwater quality. This was part of a greater effort to understand risks to drinking water. The data produced by middle level and high school students have not been accepted by experts because of concerns about method and student accuracy. We assessed the inherent errors associated with method accuracy, student precision, and sample variability to establish bounds for attainable trueness in water analyses. Analytical test kits and probes were evaluated for the determination of pH, conductivity, chloride, hardness, iron, total soluble metals, and nitrate. In terms of precision, all methods met or exceeded design specifications. Method trueness was variable and in general ranged from good to poor depending on method. A gage reproducibility and repeatability analysis of instrumental methods (pH and conductivity) partitioned the variances into student error (12‐46%), instrumental error (8‐21%), and random error (45‐68%). Overall, student‐generated data met some of the quality objectives consistent with the method limitations. Some methods exhibited a systematic bias and data adjustment may be necessary. Given good management of the student analyst process, it is possible to make precise and accurate measurements consistent with the methods specifications.
