International Saudi Arabia Students’ Level of Preparedness: Identifying Factors and Maximizing Study Abroad Experience Using a Mixed-Methods Approach

Given that students’ level of preparedness for study abroad is malleable, this study aimed to assess Saudi students’ level of preparedness academically and socioculturally to enhance their overseas experiences and success in higher education. Using a mixed methods research design consisting of survey data, semistructured interviews, and case studies with undergraduate and graduate students in a predeparture Saudi context and those enrolled in U.S. programs, the study provides empirical data to understand students’ intent to study abroad, local institutions’ contributions to preparation, and challenges encountered. Findings across datasets consistently corroborated that Saudi students are highly motivated, while articulating the need for substantive supports toward a better understanding of U.S. higher education, academic expectations, and sociocultural practices. Participants articulated the need for advanced English skills, especially academic literacies (academic writing and reading strategies) to cope with demanding workloads in graduate programs. The study discusses curricular implications for higher education in binational contexts. Journal of International Students 977
Prototype Design of Rainwater Harvesting and Solar Irrigation System for Small-Scale Farm

The current irrigation system at Taman Tanaman Dapur that used by the Faculty of Bioresources and Food Industry (FBIM) is operated manually, and the water source is directly from Syarikat Air Terengganu (SATU). The cost incurred to maintain the current system is expensive therefore, the UniSZA fund for maintenance purpose. By observing these factors, there is an opportunity to improve the irrigation system by utilising the available natural resources in the form of sun and rain, respectively, as a source of energy and water. Thus, the objectives of this project are to design and validate the prototype of rainwater harvesting and solar irrigation system for small scale farm use. By utilising the prototype, it is possible to take advantage of the available natural resources resulting in a technological advancement that optimises the energy usage producing a cost-effective, efficient irrigation system. The prototype design was carried out using a two-dimensional computer-aided design software, AutoCAD. Furthermore, the prototype development was carried out and validated with several readily-available types of equipment in the laboratory as well as equipment that could be obtained by local farmers or individuals. As a result, after going through phases of prototype creations, from the proof of concept, through mock-up testing, and pre-production, it has been well-function as designated. The value of Gross Irrigation Requirement (GIR) for this study was 308.22 mm/month while the minimum requirement of power production from the solar panel output was 0.552 kWh. More improvement can be made for further development of the prototype by integrating with other technologies such as attach it with moisture sensor and timer for the optimum condition.
Emojis and Words Work Together in the Service of Communication

We describe an experimental approach to study the relation between emojis and online language use based on tweets from a public social media platform. The novel contribution of our work derives from the application of an entropy measure to compare lexical diversity (vocabulary richness) in messages with and without emojis. We ﬁnd that lexical diversity is reliably attenuated when emojis are added to text. The pattern holds both when inﬂuence of tweet length or number of emo-jis is removed. That emojis serve to alter the lexical diversity of text in an online public context could demonstrate an in-terdependency between emojis and accompanying text in the service of communication. Our ﬁndings are consistent with the claim that the drop in lexical diversity may reﬂect a compensatory relation between emojis and words in communication. This outcome sets boundary conditions on the extent to which emoji patterning in isolation from text can qualify as a language.
DISCOVERY OF RAKING FRAUD DETECTION FOR MOBILE APPLICATION

: the mobile apps growth is increasing day by day and it’s a well know concept now days. Due to huge number of mobile apps in the market, finding ranking fraud is a big task in front of the mobile Apps market. Ranking fraud means fake or unwanted activity which have intention to up the Apps in the popularity list. In the existing system the leading event and leading session of an app is recognize from the collected past records. Based on the users feedback, tree different types of evidence taking into consideration, namely ranking based evidence, rating based evidence and review based evidence. These three evidences are aggregated by using evidence aggregation method. In the proposed system additionally, we are proposing two enhancements. Firstly, we are using Approval of scores by the admin to identify the exact reviews and rating scores. Secondly, the fake feedbacks by a same person for pushing up that app on the leader board are restricted. Two different constraints are considered for accepting the feedback given to an application. The first constraint is that an app can be rated only once from a user login and the second is implemented with the aid of IP address that limits the number of user login logged per day. Finally, the proposed system will be evaluated with real-world App data which is to be collected from the App Store for a long time period.
Political Choices of the Left and the Right in Crises: An Experimental Investigation

While numerous studies have documented the difference in choice behaviour of the political Left and the Right, the effect of situations of a crisis on political choices have remained unexplored. This study aims to record and analyse such effects and investigate if any differences or similarities appear in the two groups. The study uses an experimental approach to the problem. Samples of leftists and rightists in India are randomly provided with forms to vote in either a normal situation or a hypothetical situation of crisis. The difference in voting behaviour in the two scenarios is noted. The difference in the change in the voting behaviour of the Left and the Right is also noted. It is found as expected that under normal circumstances, the Left and the Right have different voting patterns. But under crisis, when their leader performs badly, they shift to the opposite leader with almost the same probability. Also, not only the effect, but the voting patterns themselves become very similar during crises. The behaviour of the Left and Right sustain differences only in normal circumstances, but under crises, the differences may no longer remain extant.

Modeling Emoji Generation for Emotion Analysis of Social Media Short Texts

Emojis and emoticons are widely employed in user-generated content on social media. Existing generative models for short texts do not particularly handle emojis and emoticons thereby missing the extra information conveyed by these “special” expressions. We present EmDMM , a novel Dirichlet Multi-nomial Mixture model for capturing emotions expressed through emojis and emoticons in social media short texts. EmDMM can automatically detect emoji clusters that reﬂect emotion classes providing an unsupervised tool for analyzing emotions in rapidly-emerging social media content. We apply EmDMM to COVID-19 tweets and extract public emotions on topics related to the on-going pandemic.
Didactic Continuum: the School in Digital Culture

With new technological advances in the area of Communication and Information, the knowledge gains mobility and continuous access. The dialogue between teacher and student takes another dimension, which extrapolates classroom’s time and space. In this context, the didactic instrument of communication and dialogue, which transmits the knowledge, receives influence from the means of communication and information, especially regard to Digital Technologies of Information and Communication (DTIC). As it is technical and mediation, the di-dactic have been pressed for a new composition that can favor the interaction between knowledge, the student and the teacher, who live in the digital world today. In order to understand and point out ways for a new didactic, there is a need to examine the mediation activity of the teacher. Thus, as theoretical support for this article, the Theory of Activity is indicated, as well as the studies of Comenius, Peters, Daniels, Vygostsky and Floridi's “The onlife Manifesto”, which collaborate to answer this present research. The methodology used was bibliographic, from books, articles and material made available on the internet, from
Cytotoxic Activity and Apoptosis Induction of Ethanolic Extract of Pericarps of Mangosteen (Garcinia mangostana Linn.) on WiDr Cells and Interaction Study of Alpha-mangosteen to IKK and VEGF Based on Molecular Docking

One of the compounds found efficacious as an anti-proliferative on colon cancer is alpha-mangosteen, a xanthon compound that is abundant in pericarp of mangosteen. This study focused to evaluate anticancer activity of the ethanolic extract of pericarp of mangosteen ( Garcinia mangostana Linn.) on WiDr colon cancer cells and to observe the affinity of alpha-mangosteen in inhibiting IKK and VEGF. Cytotoxic effect was tested by MTT assay and apoptosis induction was evaluated by double staining method on WiDr colon cancer cells, while interaction between alpha-mangosteen to the receptors was measured by molecular docking. The ethanolic extract was proven to have cytotoxic activity against WiDr colon cancer cells with IC 50 of 25 µg/mL. In addition, the observation of apoptosis induction by double-staining method showed that apoptosis associated the cytotoxic effect of ethanolic extract of pericarp of mangosteen (EPM) on WiDr colon cancer cells. Molecular docking showed that active compounds in pericarp of mangosteen could compete with the native ligand of VEGF because the docking score of alpha-mangosteen was almost equal with native ligand. From these results we could be concluded that the cytotoxic effect of EPM to WiDr cells was mediated by cell apoptosis. This extract was potential to be developed as chemopreventive agent. Keywords : Garcinia mangostana Linn . , cytotoxic effect, apoptosis, WiDr cell, molecular docking
Factors affecting the selection of PHB accumulating methanotrophs from waste activated sludge while utilizing ammonium as their nitrogen source

BACKGROUND Methanotrophs can offer a long-term reliable solution for two of the major problems causing environmental pollution. These microorganisms can convert methane i.e. second major GHG into biodegradable polymers as polyhydroxybutyrate (PHB). In this research, waste activated sludge was used as a seed for cultivating enrichments utilizing methane and ammonium as their sole carbon and nitrogen sources respectively with high PHB accumulation capacity. Moreover, to test the effect of different parameters as the initial ratio between the ammonium and the microorganisms (N/M), food to microorganisms ratio (F/M), the solids retention time (SRT), copper elimination and nitrate on the selection of PHB accumulating i.e. Type II methanotrophs. RESULTS After establishing a mixed culture dominated by Type II methanotrophs, the enriched culture was kept at the exponential phase of growth and had a stable performance for almost 30 consecutive cycles with a specific growth rate of 0.077±0.005hr-1 and biomass yield of 0.81±0.06 mg-VSS/mg-CH4. The PHB accumulation capacity of the enrichment reached 52.9±4% with a yield of 0.54±0.12 mg-PHB/mg-CH4. CONCLUSIONS Increasing the N/M ratio can be successfully employed to ensure the dominance of Type II methanotrophs in mixed cultures having high PHB accumulation capacity while maintaining a high F/M ratio released any inhibition resulting from ammonium co-metabolism. Despite the dominance of Type II, switching the nitrogen source to nitrate caused an invasion for Type I methanotrophs and a deterioration in the PHB accumulation of the enriched culture.
PERCEIVED DIFFICULTIES OF SCHOOL SUPERVISORS: AN EXPLORATION

Quality is a vital issue of concern for primary education system that posed a challenge for all those concerned with the system. There is an increasing advocacy for a holistic approach to quality concern in education and the holistic approach establishes the administration sub-system within the larger education system a key component of quality improvement models. Within the administration sub-system, the role efficacy and role-performance of different functionaries are important determinants of quality in education. Within this context, the block level education officers were considered as important administrative personnel and the difficulties perceived by them while on their job was explored using a phenomenological approach with 24 education officers from different districts within Varanasi Division as participants and using open-ended questionnaire and semi-structured interviews as data collection techniques. The inductive analysis of qualitative data revealed that the education officers are facing a plethora of problems that are teacher related as well as finance related. The findings of the study are expected to enrich our understanding of the performance of BEOs in light of the problems faced by them and subsequently the findings could be used by those higher in authority to further ameliorate the working conditions for the education officers at the block level thus ensuring their contribution in quality improvement of primary education.
Predicting Popularity of Polish Facebook Posts Using Author and Content Features *

Social and political discourse on social media platforms has been a persistent topic of academic study in the past decade. The question of why certain content is shared is increasingly important for understanding the impact of social media on the democratic process. In the present study we determined how well a Facebook post’s semantic content can distinguish “popular” from “unpopular” posts. Using a corpus of roughly half a million Facebook posts by Polish socio-political influencers, we conducted two experiments: the first compared the performance of topic features (obtained via topic modeling) against author features, while the second compared topic features against a bag-of-words feature set. Our first experiment showed that previous findings from Twitter cascades were replicated on our Facebook dataset: although topic features predicted popularity better than chance, they performed worse than author features. Our second experiment showed that topic features performed worse than bag-of-words features in predicting popularity. Still, in the analysis of individual (weighted) features, we found that the topic features were more inter-pretable than an ordered list of individual words, as they yielded interesting insights into the kinds of topics most likely to be shared.
Does it matter to be a part of the elite league? A study on NIFTY 50 composition changes

Nifty 50 index comprises of largest, most liquid and reputed 50 (51 from 2016) stocks listed on National Stock Exchange (NSE) India. During the index composition changes, many stocks keep entering and exiting the benchmark index and their impact is observed in the changes in the returns of a particular stock. We study the impact on abnormal returns and abnormal volume traded after Nifty index changes from the year 2000 to 2016. According to the study, positive abnormal returns get reversed for index included stocks in 60 days after the inclusion while the excluded stocks yield negative returns only in the first ten days. Using the event study analysis, the empirical findings show that after 60 to 240 days of exclusion, these stocks yield around 4% to 7% positive abnormal returns. Thus, there is an evidence of short-term impact on the returns of stocks because of inclusion or exclusion from the benchmark index. Relevant policy implications are discussed.
Shallow Meritocracy: An Experiment on Fairness Views

Meritocracies aspire to reward effort and hard work but promise not to judge individuals by the circumstances they were born into. The choice to work hard is, however, often shaped by circumstances. This study investigates whether people's merit judgments are sensitive to this endogeneity of choice. In a series of incentivized experiments with a large, representative US sample, study participants judge how much money two workers deserve for the effort they exerted. In the treatment condition, unequal circumstances strongly discourage one of the workers from working hard. Nonetheless, I find that individuals hold the disadvantaged worker fully responsible for his choice. They do so, even though they understand that choices are strongly influenced by circumstances. Additional experiments identify the cause of this neglect. In light of an uncertain counterfactual state -- what would have happened on a level playing field -- participants base their merit judgments on the only reliable evidence they possess: observed effort levels. I confirm these patterns in a structural model of merit views and a vignette study with real-world scenarios.
Vicarious Bullying and Career Progression of African American Women Academics: An Integrative Literature Review

The purpose of this literature review was to explore research on the role of vicarious bullying in African American women's academic career progression. This study is framed by the three key concepts of academic bullying, vicarious bullying in higher education and unethical leadership, and the interface of Black women's intersectionality, academic bullying, and career progression. Scholars have confirmed that women of color are more likely to endure vicarious bullying leading to career disruption, yet their voices remain absent from the extant literature. Leadership that chooses to ignore the malicious behavior enables workplace bullying and unhealthy behavior to grow until it can destroy the organization's potential and incur substantial costs. Gaps identified in the literature and recommendations for practice and scholarly research may contribute to positive social change by informing human resource professionals in higher education settings on African American women academics' vulnerability to become workplace bullying targets.
Novel Cost-effective Technique for Continued Operation of Electrical Equipment During Voltage Sag

This research focuses on mitigating voltage sags at the control level through a cost-effective method using mini dynamic sag corrector at low voltage systems and proposing control level embedded solutions for equipment design and modifying the technical aspects of electrical devices to facilitate the control circuit to ride-through voltage sags. Voltage sags also known as “dips” are a common cause of power disturbances. These are temporary voltage drops below 90% of the nominal voltage caused by a sudden increase in loads or short circuits and faults lasting up to 170ms. Voltage sag in distribution networks can adversely affect sensitive electrical equipment in industrial processes, such as production and manufacturing, resulting in substantial financial losses of up to $1.5 million/day. Various types of electrical equipment are susceptible to voltage sags but are not limited to power supplies, relays, contactors, variable frequency drives, and programmable logic controllers. In this method, the cost-effective MiniDySCs were installed in the industrial plant to compensate for the missing voltage in the lines during a sag event. Also, modifications to technical aspects of Contactors, Relays, and VFDs are proposed to provide more robust results for the control circuits to ride through voltage sags even up to 40% of the nominal voltage-drop.
The biological basis of Marvel Comics mutants

“Feared and hated by a world they have sworn to protect” is the catchphrase always present in nearly all comics of Marvel’s mutants, the X-Men. This phrase was coined by Stan Lee, the co-creator of the X-Men together with Jack Kirby. A popular proverb states that “we fear what we do not understand” and this is probably the case with the mutants within Marvel’s comic book universe. Therefore, the question is: can we understand Marvel’s mutants? That is the main aim of this essay.
Assessment of criterion validity of personality disorder diagnosis in adolescents and relations between attachment style and personality disorder diagnosis

Aim. Assessment of criterion validity and temporal stability of personality disorder diagnosis in adolescents and relationships between attachment styles and personality disorder diagnosis. Material and methods. 50 adolescents (46 girls and 4 boys, aged 15–17) hospitalized at the department of child and adolescent psychiatry were assessed with the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II) and the Inventory of Parent and Peer Attachment (IPPA). After one year, adolescents meeting the criteria for a personality disorder (PD) diagnosis were reassessed with the SCID-II. Results. In the first stage of assessment, diagnostic criteria for different types of personality disorders were met by 41 adolescents (82%) (mean number of criteria = 5.9). Criteria were met most often for borderline personality disorder (BPD) (n = 26; mean number of criteria = 7.9). In the second stage of assessment, the interview was re-administered to 21 adolescents (51%); the mean number of criteria was = 6.6. A statistically significant relationship between the number of PD diagnostic criteria in assessment one and the number of criteria in assessment two was obtained (r = 0.58; p < 0.01). 82% of the participants with PD were insecurely attached to their mothers. In the borderline group, 83% of the participants reported anxious-avoidant attachment style. Conclusions. PD traits in adolescence, specifically BPD, are stable across one year.
Learning to Sequence and Blend Robot Skills via Differentiable Optimization

In contrast to humans and animals who naturally execute seamless motions, learning and smoothly executing sequences of actions remains a challenge in robotics. This letter introduces a novel skill-agnostic framework that learns to sequence and blend skills based on differentiable optimization. Our approach encodes sequences of previously-defined skills as quadratic programs (QP), whose parameters determine the relative importance of skills along the task. Seamless skill sequences are then learned from demonstrations by exploiting differentiable optimization layers and a tailored loss formulated from the QP optimality conditions. Via the use of differentiable optimization, our work offers novel perspectives on multitask control. We validate our approach in a pick-and-place scenario with planar robots, a pouring experiment with a real humanoid robot, and a bimanual sweeping task with a human model.
