The Relationship between Personality Trait and Social Media Addiction

The booming in telecommunications made social media an essential part of human daily lives [1]. Social media has become very popular type of media which have many attributes and features that provides a lot of services like a way of communicating, texting, picture sharing, audio and video sharing, quick publishing or posting,learn and share information instantaneously making the world look like a small village [2]. Social media sites allow people to communicate and interact with each other; as a result, the number of social media users has seen rapid growth over the last few years across the earth [3]. Social media sites provide platforms where users can meet and form online communities. Also, marketing professionals are increasingly using social media to connect with audiences. As a result, social media sites have become a new social tool [4]. Over the last few years, the use of social media has become an increasingly popular leisure activity in many countries across the world [2]. Given their social-oriented characteristics, social media sites provide their users with an enjoyable interaction experiences. However, despite these benefits,social media has brought about detrimental side effects to society and these experiences may encourage users to uses these platforms extensively and hence results in addictive use behaviors.That the nature of social media is easy, entertaining and cost effective encourages individuals to stay long in it.
Answers to Anonymous Referees 1 and 2 on the paper ’Does the rotational direction of a wind turbine impact the wake in a stably stratified atmospheric boundary layer?’

Stably stratified atmospheric boundary layers are often characterized by a veering wind profile, in which the wind direction changes clockwise with height in the Northern Hemisphere. Wind-turbine wakes respond to this veer in the incoming wind by stretching from a circular shape into an ellipsoid. We investigate the relationship between this stretching and the direction of the turbine rotation by means of large-eddy simulations. Clockwise rotating, counterclockwise rotating, and non-rotating actuator disc turbines are embedded in wind fields with no wind veer or in wind fields with an Ekman spiral rep5 resentative of the Northern Hemisphere, resulting in six combinations of rotor rotation and inflow wind condition. The impact of the Coriolis force via the Ekman spiral depends on the rotational direction of the actuator disc, whereas the direction of the disc rotation exerts little impact if no veer is present. The differences result from the interaction of the actuator rotation with the Ekman spiral and are present in the zonal, the meridional, and the vertical wind components of the wake. The interaction of the Ekman spiral with both rotational directions lead to two different flow fields characterizing the wake. In the case of a 10 counterclockwise rotating actuator disc, the rotational direction of the wake persists in the whole wake. In case of a clockwise rotating actuator, however, the rotational direction is different in the near wake in comparison to the far wake. The physical mechanism responsible for this difference is explained by a simple linear superposition of the inflow wind field, characterized by vertical wind shear and wind veer, with a wind-turbine model including a Rankine vortex, representing the rotational effects imposed on the flow by the rotating blades. 15 Copyright statement.

REAL WELLBEING OF THE UMMAHAND ECONOMIC PERFORMANCE: Islamic Perspectives and Empirical Evidence

This study provides insights into real wellbeing of the Ummah (Muslim community) using Islamic perspectives and empirical evidence. Islam places justice at center in economic interactions. In Islamic teachings, justice is a prerequisite for human wellbeing and economic development. Ibn Khaldun has devoted a whole section on justice entitled: injustice triggers the destruction of civilization. Nevertheless, justice cannot be fully realized without asabiyah, which is also referred to as social solidarity, group feeling or social cohesion. This study focuses on social solidarity to determine its causal links with the economic performance of the Ummah. The study employs a comprehensive measure of social solidarity of a society that is based on three indices namely social cohesion, interpersonal safety, trust and civic activism. The results show that social solidarity plays a positive and significant role in determining the economic performance of the Ummah. This finding is shown to be robust to different control variables, different specifications, econometric techniques and the outliers.
Experimental study of large scale fluidized beds at elevated pressure

Simultaneous electrical capacitance tomography measurements for two planes were performed to obtain detailed information on bubble characteristics in a pressurized fluidized bed. Average permittivity values were used to get estimates of bubble sizes, while cross correlation was applied to the signals of both planes to obtain average bubble rise velocities. At low pressures, a wide variation in bubble size was observed. Large stable bubbles tend to affect fluidization smoothness significantly. At higher pressure, bubbles possessed a more uniform size and were in general smaller. Consequently fluidization behavior was observed to be smoother at higher pressures.
In situ online biomonitoring of groundwater quality using freshwater amphipods exposed to organic fertilizer and rainfall events

Nitrate levels originating from agricultural fields can reach groundwater concentrations far above the allowed threshold values. In this context we studied the effects of pig manure applied as fertilizer on a field with crop during several simulated rain events. The effects on groundwater crustaceans were monitored continuously using the Multispecies Freshwater Biomonitor (MFB) adapted to groundwater conditions and for application in the field. Gammarus fossarum (Koch, 1835) and Niphargopsis casparyi (Pratz, 1866) served as indicator species in the biomonitor. Pig manure was applied on the test field, once spiked with sulfamethoxazole. Three rainfall events of different intensity and duration were simulated directly after the fertilization and the responses of the animals were quantitatively recorded in the online biomonitor for 24 h to 7 days. G. fossarum responded within 24 h with decreasing spontaneous locomotor activity to elevated Nitrate levels being washed out from the surrounding soils. N. casparyi responded in two experiments of 7 days’ duration with decreasing activity to elevated Nitrate levels in the 1 experiment and in the 2 experiment to increased Nitrite and sulfamethoxazole levels showing decreased activity and 62.5% mortality. The three field experiments showed (1) successful operation of the online biomonitor MFB in situ, (2) G. fossarum sensitivity to Nitrate, (3) groundwater crustaceans’ sensitivity to Nitrate, Nitrite and sulfamethoxazole. We recommend the use of subterraneous crustacean species for online biomonitoring of groundwater quality in agricultural areas as an effective measure to assess excess nutrients and pollutants aiming at subsequent reduction and compliance to the European groundwater directive.

FINANCIAL LITERACY AND PERFORMANCE OF SMALL AND MEDIUM SCALE ENTERPRISES IN BENUE STATE, NIGERIA

This study the effect of financial knowledge on the performance of Small and Medium Scale Enterprises (SMEs) in Benue State, Nigeria. The study was anchored on theDual –Process Theory.The researcher used both primary and secondary sources from a sample of 154 respondents obtained by the use of a well structured questionnaire. The data collected were analyzed using descriptive statistics such as frequency, simple percentage and the relationship between the variables of the model was tested using multiple linear regression analysis. The result of the regression analysis indicates that the probability value of the regression analysis was used to test the first hypothesis at 5 % level of significance and the p-value (0.002) was lower than the significance level this means that the null hypothesis was rejected and the alternative accepted. This result can be statistically given as p-value 0.002< α = 0.05. The second hypothesis was tested at 5 % level of significance and the p-value (0.328) was greater than the significance level, tis means that the second null hypothesis was accepted. This result can be statistically given as p-value 0.328 > α = 0.05. The probability value of the regression analysis was used to test the third hypothesis at 5 % level of significance and the p-value (0.000) was lower than the significance level meaning that the null hypothesis was rejected and the alternative accepted. This can be statistically given as p-value 0.000 < α = 0.05. It was concluded that financial knowledge and attitudes influences SMEs performance. It was recommended among others that there is a need for training programs on budgeting and planning, debt management, record keeping; saving and retirement plans in schools and other institutions that seek to promote financial literacy and practice.
ANALYSIS OF ACCOMPANIMENT PERFORMANCE IN VILLAGE DEVELOPMENT IN POLEWALI MANDAR REGENCY

The purpose of this study is to describe and analyze the performance of assistance in the development of villages in Polewali Mandar Regency. The design of this study is qualitative with a case study research approach. The type of research used is descriptive research type. In this study, data collection techniques used were observation, in-depth interviews, and documentation. The informants in this study were the Village Head, Village Consultative Body, Village Facilitator, Village Local Assistance, and Community Leaders. The stages of qualitative data analysis are carried out namely data reduction, data presentation, and drawing conclusions. The results of the study showed that the pattern of recruitment as well as the process of training and provisioning to village assistance officers was not optimal, although it was accompanied by formal normative requirements in its implementation. The village assistance program has not yet fully led to the development of village innovation, although it appears that community engagement efforts have been carried out as mandated by law. the assistance process in village development is only a relationship between the village facilitator and the village government or the village head only. The assistance that is carried out in village development has no influence. This perception can be seen from the muddle of information obtained by researchers from each stakeholder in the village. Although on the other hand it is said that the relationship between village facilitators, the village government and the community is going well. This does not affect the objectives of the assistance to realize active community participation.
Modeling the Surface Structure and Reactivity of Pyrite: Introducing a Potential Model for FeS2

Atomistic simulation techniques are used to investigate the surface structure, stability and reactivity of pyrite. We introduce a potential model for FeS2 which reproduces experimental structural parameters, elastic constants and hydration energies of pyrite. We modeled the {100}, {110}, and {111} surfaces of pyrite and calculated the {100} surface to be the most stable and to show little surface relaxation, in agreement with experiment. The surfaces were hydrated by associative adsorption of water molecules which stabilized all three surfaces, especially the unstable {111} surface. The calculated adsorption energy of −47 kJ mol-1 for water on the {100} surface agrees well with an adsorption energy of −42 kJ mol-1, determined for the stoichiometric (100) surface by temperature-programmed desorption.1 Adsorption of water molecules at surface sites of lower coordination (four- or three- coordinated) showed increased reactivity of these sites. We calculated an increase in adsorption energy of 50−60 kJ mol-1 .
The Correlation between Self-Confidence and Students’ English Achievement of Tertiary Students at Universitas Advent Indonesia

Self-confidence is one of the important factors in determine students’ English achievement. This study aims to find out the correlation between self-confidence and students’ English achievement and to answer the question of the hypothesis there is a correlation between self-confidence and students’ English achievement. The sample of this study were 30 tertiary students of English Language Education study program at Universitas Advent Indonesia. A questionnaire was used to gather the data, the questionnaire consisted of 20 questions and used the five-point Likert scale. The questionnaire was given to the students to measure their self-confidence and then correlated the questionnaire result with the students’ English achievement grade. The Spearman’s Coefficient of (Rank) correlation was used in order to answer the question of the correlation between the self-confidence and the students’ English achievement and the data was calculated using SPSS. The result showed that there is no significant correlation between self-confidence and students’ English achievement. However, since there is no enough evidence, the 𝐻 " cannot be rejected. For future researchers, it is recommended to do another study with enough data and evidence with different level of students and different aspect of English skills such as speaking.
Physical mechanism for origin of streamwise vortices in mode A of a square-section cylinder

In the present paper, physical mechanism responsible for origin of streamwise vortices in mode A appeared in the threedimensional (3-D) wake transition of a square-section cylinder is investigated. Direct numerical simulations at a Reynolds number of 180 firstly show that such streamwise vorticity is not originated from lateral surfaces. Then through the analysis of local flow field in the immediate neighborhood of rear surface, based on the theory of vortex-induced vortex, a new physical mechanism is identified. At first, the vertical vorticity on rear surface is generated by the intrinsic three-dimensional instability with the same instability wavelength of mode A. Then the streamwise vorticity at a specific sign is induced by such vertical vorticity, convected and concentrated in the shear layers. Finally, streamwise vortices are formed and shed with alternatively shedding spanwise vortices in the near wake. Moreover, the effect of induced spanwise vorticity on original two-dimensional (2-D) spanwise vorticity is also presented in detail.
A Flotation Collector for the Separation of Unburned Carbon from Fly Ash

ABSTRACT A very good separation of unburned carbon from fly ash was achieved with a laboratory flotation machine by employing a mixture of 4-dodecylphenol (DDP) and hexadecane (HXD) as a collector. No other reagent was required. Good results were obtained by recleaning either the concentrate or the tailings in two-stage flotation tests. Therefore, it was possible to reduce the carbon content of a selected fly ash from an initial level of 25% to a final level of 6.0% or less. At the same time it was possible to recover 87–95% of the carbon in the concentrate and 70–80% of the fly ash in the tailings by recleaning the concentrate. The lowest fly ash carbon content (2-3%) was realized by recleaning the tailings, but this also reduced fly ash recovery.

BCD deduplication: effective memory compression using partial cache-line deduplication

In this paper, we identify new partial data redundancy among multiple cache lines that are not exploited by traditional memory compression or memory deduplication. We propose Base and Compressed Difference (BCD) deduplication that effectively utilizes the partial matches among cache lines through a novel combination of compression and deduplication to increase the effective capacity of main memory. Experimental results show that BCD achieves the average compression ratio of 1.94× for SPEC2017, DaCapo, TPC-DS, and TPC-H, which is 48.4% higher than the best prior work. We also present an efficient implementation of BCD in a modern memory hierarchy, which compresses data in both the last-level cache (LLC) and main memory with modest area overhead. Even with additional meta-data accesses and compression/deduplication operations, cycle-level simulations show that BCD improves the performance of the SPEC2017 benchmarks by 2.7% on average because it increases the effective capacity of the LLC. Overall, the results show that BCD can significantly increase the capacity of main memory with little performance overhead.
On The Relationship Between Speech-Based Breathing Signal Prediction Evaluation Measures and Breathing Parameters Estimation

The respiratory system is one of the major components of the speech production system. Any alteration in breathing can result in changes in speech. Specific breathing characteristics, such as breathing rate and tidal volume, can indicate a person’s pathological condition. More recently, neural network-based methods have started emerging for predicting the breathing signal from the speech signal. The neural networks are trained and evaluated with different objective measures, such as mean squared error (MSE) and Pearson’s correlation. This paper investigates whether there is a systematic relationship between the different objective measures used for training and evaluating the neural network models and the end-goal, i.e. estimation of breathing parameters such as, breathing rate and tidal volume. Our investigations on two different data sets with two different neural network-based approaches show that there is no clear systematic relationship. In other words, obtaining a high Pearson’s correlation on the evaluation set does not necessarily mean better breathing parameter estimation. Thus, indicating the need for developing other objective evaluation measures.
Predictors of Suicidal Ideation Among Formerly Incarcerated People During the COVID-19 Pandemic

Background and purpose: Formerly incarcerated people die by suicide at a rate 6.75 times higher than the general population, but previous research has not identified factors that contribute to this heightened risk. The conditions of the COVID-19 pandemic may exacerbate both suicide risk factors and the stressors of reentry. In the framework of stress proliferation theory, this study uses path analysis to identify paths from incarceration history to environmental factors (i.e., financial stress), interpersonal factors (i.e., social support and conflict), psychological factors (i.e., depression and existential isolation, the feeling of being alone in one’s subjective experience), and their subsequent relationship with suicidal ideation. Method: I examined cross-sectional survey data collected June-July, 2020 from American participants (n = 946) over the Amazon Mechanical Turk (MTurk) platform. Results: Indices of fit indicated poor fit of the path analysis model to the data. However, the majority of the pathways within the model reached significance. Specifically, incarceration predicted suicidal ideation by way of its relationship to financial concern and subsequent conflict and depression. In addition, incarceration predicted lower emotional support, which in turn predicted depression and suicidal ideation. Existential isolation mediated the relationship between incarceration and suicidal ideation. However, the pathways testing whether incarceration predicted existential isolation indirectly (by way of its relationship with emotional support and conflict), were not significant. In follow-up analyses, formerly incarcerated individuals who spent over six months incarcerated reported more suicidal ideation, existential isolation, and loss of meaning than those who spent less than six months incarcerated. Finally, the magnitude of the following relationships was stronger among those with an incarceration history than in those without: 1) financial concern and conflict, 2) financial concern and depression, 3) conflict and existential isolation, and 4) existential isolation and suicidal ideation. Implications: Reentry programs may target existential isolation and emotional support through connecting formerly incarcerated individuals with others with similar lived experiences. Policy changes that ease the financial burdens placed on formerly incarcerated individuals may also have positive downstream effects on their interpersonal relationships and emotional health.
