Detecting Fake Reviews through Sentiment Analysis Using Machine Learning Techniques

— Recently, Sentiment Analysis (SA) has become one of the most interesting topics in text analysis, due to its promising commercial benefits. One of the main issues facing SA is how to extract emotions inside the opinion, and how to detect fake positive reviews and fake negative reviews from opinion reviews. Moreover, the opinion reviews obtained from users can be classified into positive or negative reviews, which can be used by a consumer to select a product. This paper aims to classify movie reviews into groups of positive or negative polarity by using machine learning algorithms. In this study, we analyse online movie reviews using SA methods in order to detect fake reviews. SA and text classification methods are applied to a dataset of movie reviews. More specifically, we compare five supervised machine learning algorithms: Naïve Bayes (NB), Support Vector Machine (SVM), K-Nearest Neighbors (KNN-IBK), KStar (K*) and Decision Tree (DT-J48) for sentiment classification of reviews using two different datasets, including movie review dataset V2.0 and movie reviews dataset V1.0. The measured results of our experiments show that the SVM algorithm outperforms other algorithms, and that it reaches the highest accuracy not only in text classification, but also in detecting fake reviews.
Validity and Reliability of the Persian Version of Language Screening Test (LAST) for Patients in the Acute Phase of Stroke

Background & Objectives: Aphasia is one of the most common consequences of a stroke; thus, screening tests for early diagnosis of the problem are necessary when dealing with aphasia patients. One of these screening tests is the Language Screening Test (LAST). The purpose of this study was to translate, validate, and utilize this test in the Persian language for patients after stroke. Methods: The original version of LAST was translated into Persian, and then administrated on 100 patients in the acute phase by two examiners at the patient’s bedside in order to check the inter-rater reliability. To assess the agreement between the two forms (a and b) of the LAST, Concordance Correlation Coefficient (CCC), weighted Kappa, and Intraclass Correlation Coefficient (ICC) were used. Also, the Persian version of LAST and the Western Aphasia Battery (WAB) were performed at the chronic phase with two independent examiners with blind scoring. Results: Inter-rater reliability between Rater 1 and Rater 2 on LAST-a and LAST-b score were very good for both phases. The CCC for LAST-a and LAST-b, respectively, were 0.874 and 0.865 for the acute phase and 0.923 and 0.927 for the chronic phase. The weighted Kappa for LAST-a and LAST-b, respectively, were 0.750 and 0.740 for the acute phase, and 0.822 and 0.846 for the chronic phase. Conclusion: The obtained results showed that LAST is a very simple, fast, and valid test and can be used as a reliable tool in stroke patients. Lack of cultural and language dependency are the advantages of using this test.
Job Satisfaction and Organizational Performance: Empirical Evidence from Pakistan's Banking sector

This research investigates the relationship between five factors of job satisfaction and organizational performance in Pakistan's banking sector. In this sense, to analyze the structural and measurement model relations between the constructs, 280 valid questionnaires were composed of employees from Pakistan's banking sector. In this study, partial least square (PLS) 3.2. 9 were used, whereas both the Fornell-Larcker criteria and the Heterotrait-Monotrait ratio (HTMT) were used discriminant validity in this study. For organizational performance, supervision, fringe benefits, and contingent rewards were suitable. This study's mixed findings have indicated that specific hypotheses such as pay and promotion have been rejected depending on their connection to organizational performance. The survey results in significant consequences for bank executives and decision-makers, and researchers and illustrates the relevance of banks' performance. This research sheds new light on the relationship between the job satisfaction survey by spector's (1985), including pay, promotion, supervision, fringe benefits, and contingent rewards with organizational performance. It seems to be the various research suggested in the banking sector of Pakistan.
ACUTE TOXICITY MERCURY CHLORIDE AGAINST TRICHOPTERA LARVA

Mercury waste from gold mining activities that pollutes the environment is hazardous for life, including aquatic insects. The acute toxicity of mercury in LC50in the larvae of Trichoptera aquatic insects, which are often used as insect bioindicators of water quality, was determined in this study. A completely randomized design with various concentrations of mercuric chloride (HgCl2) was applied. A total of six concentration levels, namely: control (0.00); 0.001mg / l; 0.005 mg / l; 0.1 mg / l; 0.2 mg / l; 0.3 mg / l HgCl2 were tested. Each treatment was repeated three times. At each test concentration, 20 Trichoptera larva were used. The Trichoptera larva were exposed to the mercury solution in a 250 ml beaker with a 100 ml solution volume. The Trichoptera larva mortality was observed at 30 minutes, 60 minutes, 1.5 hours, and 48 hours after exposure. The results showed that the larva’ mortality had occurred in the observation 30 minutes after exposure, namely 2% mortality at a concentration of 0.005 and reaching 45% at a concentration of 0.3 mg l. The higher the mercury content in the water, the higher the mortality of the test larvae. The concentration of 0.048 ppm is the LC50 value of mercuric chloride for Trichoptera larvae. This study shows that mercuric chloride is a compound with acute toxicity. Mercury exposure to the larvae can also cause physiological reactions that cause observable morphological changes. Trichoptera larvae exposed to mercury showed signs of a defect in blackening the trachea gills and spread throughout the body. At 24 hours after exposure, the larval body becomes stiff and black.
Influence of Environment and Gender on Career Choice among Secondary School Students in Kaura Local Government Area, Kaduna State, Nigeria

The study examined the influence of environment and gender on career choice among secondary school students in Kaura Local Government of Kaduna State. A descriptive research design was used and 18 secondary schools were clustered into three chiefdoms to draw a sample of 6 secondary schools using purposive sampling technique. Also, a sample of 422 students from a population of 3558 students from the three Chiefdoms was drawn using cluster sampling technique. The study developed and used a questionnaire tagged 'Environment, Gender and Career Choice Questionnaire (EGCCQ)' with correlation coefficient of 0.78. The students' career choice was based on the adoption of Career Interest Survey (CIS) and Vocational Interest Inventory (VII) developed by Bakare (1977). Descriptive statistics of simple percentage was used for the research question generated, while inferential statistics of multiple regression analysis was employed to analyse the null hypotheses developed for the study and tested at 0.05 level of significance. The findings revealed that students had preferences for career choice based on gender and environment. There was a significant composite influence of environment and gender on career choice among secondary school students in Kaura Local Government of Kaduna State, with the influence of environment being relatively than that of gender. It is therefore recommended among others that students should be well counselled in the choice of career process by professional counsellors and they should take into consideration the immediate environment of the students, their gender, interest, ability, skills and personality.
Morphometric and Meristic Variability in Butis koilomatodon (Gobiiformes: Eleotridae) in Estuarine and Coastal Areas of the Mekong Delta

The study aimed to investigate morphometric and meristic variability in the mud sleeper Butis koilomatodon (Bleeker, 1849) in the Mekong Delta. This species is a commercial fish species with a small-size and is mainly distributed in some coastal areas from Tra Vinh to Ca Mau provinces. In the present research, the parameters of morphometry and measurement, including the head length, body depth, eye diameter, distance of the two eyes, and the interrelationships among the morphometric variables, were determined. The results revealed that the total length and weight of the fish changed by sex, season, habitat, and the interaction between the seasons and habitats. Likewise, the meristic criteria were different between males and females, and the dry and wet seasons, but not by their interactions. The growth rate of males was faster than females. The outcomes also showed that the body size of this species was larger in the dry season and the largest fish were found in Duyen Hai and Tra Vinh provinces. The Findings would be useful not only for further effects of environmental factors on morphology but also for comparisons between congeners Butis morphologically.
DNA damage in homocystinuria: 8-oxo‑,8‑dihydro‑2’-deoxyguanosine levels in cystathionine-β-synthase deficient patients and the in vitro protective effect of N-acetyl‑L‑cysteine

Introduction: Homocysteine (Hcy) tissue accumulation occurs in a metabolic disease characterized biochemically by cystathionine β-synthase (CBS) deficiency and clinically by mental retardation, vascular problems, and skeletal abnormalities. Previous studies indicate the occurrence of DNA damage secondary to hyperhomocysteinemia and it was observed that DNA damage occurs in leukocytes from CBS-deficient patients. This study aimed to investigate whether an oxidative mechanism could be involved in DNA damage previously found and investigated the in vitro effect of N-acety-L-cysteine (NAC) on DNA damage caused by high Hcy levels. Methods: We evaluated a biomarker of oxidative DNA damage in the urine of CBS‑deficient patients, as well as the in vitro effect of NAC on DNA damage caused by high levels of Hcy. Moreover, a biomarker of lipid oxidative damage was also measured in urine of CBS deficient patients. Results: There was an increase in parameters of DNA (8-oxo-7,8-dihydro-2’- deoxyguanosine) and lipid (15-F2t-isoprostanes levels) oxidative damage in CBS-deficient patients when compared to controls. In addition, a significant positive correlation was found between 15-F2t-isoprostanes levels and total Hcy concentrations. Besides, an in vitro protective effect of NAC at concentrations of 1 and 5 mM was observed on DNA damage caused by Hcy 50 μM and 200 μM. Additionally, we showed a decrease in sulfhydryl content in plasma from CBS-deficient patients when compared to controls. Discussion: These results demonstrated that DNA damage occurs by an oxidative mechanism in CBS deficiency together with lipid oxidative damage, highlighting the NAC beneficial action upon DNA oxidative process, contributing with a new treatment perspective of the patients affected by classic homocystinuria. Keywords: Cystathionine-β-synthase deficiency; oxidative stress; 8-oxo-7,8-dihydro- 2’-deoxyguanosine; homocysteine; DNA damage; N-acetyl-L-cysteine

Matching Entities from Multiple Sources with Hierarchical Agglomerative Clustering

: We propose extensions to Hierarchical Agglomerative Clustering (HAC) to match and cluster entities from multiple sources that can be either duplicate-free or dirty. The proposed scheme is comparatively evaluated against standard HAC as well as other entity clustering approaches concerning efﬁciency and efﬁcacy criteria. All proposed algorithms can be run in parallel on a distributed cluster to improve scalability to large data volumes. The evaluation with diverse datasets shows that the new approach can utilize duplicate-free sources and achieves better match quality than previous methods.
Detention and Release in Rectangular Gabion Weir

The present paper aims to study the mechanization of detention and release processes when a rectangular gabion weir is used in lined irrigation canals as the preliminary solution to treat the problem of lowering water levels generally during the summer season. At this study a laboratory flume canal with dimensions of 10.0 m long by 0.3 m wide and 0.5 m high was used to carry out the weir experiments. The used hydraulic model constructed with dimensions of 0.3 m width by 0.4 m height, and five different lengths of 0.4, 0.6, 0.8, 1.0, and 1.2 m respectively. Whereas the used gravel samples, as filling material, were of monosized gravel with diameters ranged between 9.5-14.0, 14.0-19.0, 19.0-25.0, 25.0-37.5, and 37.5-50 mm respectively. While the measured discharge values during the experiments were in the range of 0.0007-0.015. 0 m3/s, they reached a total of 194 test runs. The results showed that the upstream water depth, as Detention depth, is directly proportional to both of the discharge and the length of the weir, and inversely proportional to the diameter of the used gravel sample, the downstream water depth, as Release depth, is directly proportional with discharge, simultaneously there is no clear effect for both the length weirs length and the used gravel sample on it‘s value. Finally, both values of detention and release depths are directly proportional to each other. A series of empirical formulas were made for designers to manage detention and release processes for this type of weirs.
Numerical analysis of ultimate load and crack propagation in a concrete beam with longitudinal small hole

This analytical study aims to investigate the flexural behavior of simply supported RC beams having longitudinal hole with circle cross section under monotonic two point loads. The commercial FE program ABAQUS was used for simulating and implementing the specimens behavior that tested experimentally in previous researches. The overall specimens investigated were thirteen RC rectangular beam specimen, the first one was solid while the others with longitudinal circular hole. The specimens with holes divided into three groups, each one has a specified hole diameter 25 mm, 40 mm, and 50 mm. The distance from center of hole to the top section face was variable where the hole would be completely in the stress block, below it, or partially within it. The validity of the simulated model were verified by comparing the available load deflection data with the implemented one, where good agreement were noticed. The simulated models could introduce the ultimate load, first cracking load and its propagation in addition to the maximum attended deflection. It is concluded that the existence of a longitudinal hole with a percentage of diameter to beam depth ratio below 20% with different positions from top surface of the cross-section to the center of the hole values caused decreasing in ultimate load not exceeding 5% compared with the solid beam.
Short Review on Reinforced Concrete Beam - Column Joint : Earthquake Response and Rehabilitation Techniques

It is highly recognized throughout the entire literature that there are many serious attempts to investigate the structural behavior of Reinforced concrete (RC) beam column joint. These studies tried to cover many key elements that usually govern the intended behavior of such structural element. It can be also from any simple survey during that literature that the reported failures in the past confirm the fact that the used design methods did not play the required role in providing good safe design. The most classic trend in strengthening the reinforced concrete joints was the addition of transversal bars. However, there are agreements throughout the recent contributions that increasing the level of reinforcement illustrated and optimum value and the extra addition may give negative results. In contrast, many alternative rehabilitation techniques were examined in the past such as Slurry Infiltrated Fiber Reinforced Concrete (SIFCON) blocks and Fiber Reinforced Polymer (FRP) sheets which gave good results regarding mechanical strength, stiffness and ductility behavior. The current study tries to present an overview with respect to past research programs that deals with such concern of science.
Manufacture of shape memory alloys NiTi and NiTiCu by casting method and studying the effect of adding the copper element in different proportions to the binary alloy on the microstructure, phase transformations and conductivity

Thanks to unique properties, such as light weight, good biocompatibility, high strength, and relatively low cost, shape memory alloys are of interest to researchers. In this work alloys NiTi and NiTiCu with different weight percents were made from the copper element using the casting method by (VAR) furnace. Where the elements were melted at (1350°C) without a crucible to obtain best alloys of high purity, and after that the manufactured ingots were cooled with ice water to obtain the best homogeneity. The melting process was followed by the annealing process by an electric furnace at (750°C). After completing the manufacturing process, specimens were prepared for microscopic and mechanical tests, and wires were drawn for the purpose of electrical testing. Several tests and examinations were carried out to ensure that the alloys manufactured are SMAs. The microscopic examinations that were performed via OM showed that the copper element is uniformly distributed within a NiTi matrix. The results showed FESEM that the microstructure is symmetric and homogeneous, and also showed phase (TI 002) and (Ti2Ni) and some defects. DSC examination showed the initial and final degrees of the austenite and martensite phase. In addition, the results of DSC showed that the best stable alloys are alloy NiTi and NiTiCu-3 and that the hysterical loop decreases with an increase in the percentage of copper. The results of the shape memory effect showed that the best SME was (88.98%) for alloy NiTiCu-3. As for the microhardness, it increased when the copper element was increased, so the maximum hardness of the specimen was at 2 wt. % Cu, and it seemed to decrease with the increase in the copper element. The electrical test that was performed using the 4T sensing method of wires showed that the conductivity value increases with the increase in ratio of Cu with the decrease in the resistance. The best conductivity ratio was for alloy NiTiCu-3 where the conduction ratio was 24096.4 (Ω.Cm)−1 and it had the lowest resistivity 41.5 (Ω.Cm)10−6. Strain rate was tested and the resistivity, so the increase in the strain rate was observed with the increase in the copper element and the decrease in the resistivity.
Nanomechanical and Molecular Characterization of Aging in Dentinal Collagen

Methylglyoxal (MGO) is an important molecule derived from glucose metabolism with the capacity of attaching to collagen and generating advanced glycation end products (AGEs), which accumulate in tissues over time and are associated with aging and diseases. However, the accumulation of MGO-derived AGEs in dentin and their effect on the nanomechanical properties of dentinal collagen remain unknown. Thus, the aim of the present study was to quantify MGO-based AGEs in the organic matrix of human dentin as a function of age and associate these changes with alterations in the nanomechanical and ultrastructural properties of dentinal collagen. For this, 12 healthy teeth from <26-y-old and >50-y-old patients were collected and prepared to obtain crown and root dentin discs. Following demineralization, MGO-derived AGEs were quantified with a competitive ELISA. In addition, atomic force microscopy nanoindentation was utilized to measure changes in elastic modulus in peritubular and intertubular collagen fibrils. Finally, principal component analysis was carried out to determine aging profiles for crown and root dentin. Results showed an increased presence of MGO AGEs in the organic matrix of dentin in the >50-y-old specimens as compared with the <26-y-old specimens in crown and root. Furthermore, an increase in peritubular and intertubular collagen elasticity was observed in the >50-y-old group associated with ultrastructural changes in the organic matrix as determined by atomic force microscopy analysis. Furthermore, principal component analysis loading plots suggested different “aging profiles” in crown and root dentin, which could have important therapeutic implications in restorative and adhesive dentistry approaches. Overall, these results demonstrate that the organic matrix of human dentin undergoes aging-related changes due to MGO-derived AGEs with important changes in the nanomechanical behavior of collagen that may affect diagnostic and restorative procedures in older people.
The immunogenicity of midbrain dopaminergic neurons and the implications for neural grafting trials in Parkinson’s disease

Abstract Dopaminergic (DA) cell replacement therapies are a promising experimental treatment for Parkinson’s disease (PD) and a number of different types of DA cell-based therapies have already been trialled in patients. To date, the most successful have been allotransplants of foetal ventral midbrain but even then, the results have been inconsistent. This coupled to the ethical and logistical problems with using this tissue has meant that an alternative cell source has been sought of which human pluripotent stem cells (hPSCs) sources have proven very attractive. Robust protocols for making mesencephalic DA (mesDA) progenitor cells from hPSCs now exist and the first in-human clinical trials have or are about to start. However, while their safety and efficacy are well understood, relatively little is known about their immunogenicity and in this review, we briefly summarise this with reference mainly to the limited literature on human foetal DA cells.
