Sentiment Classifier: Logistic Regression for Arabic Services' Reviews in Lebanon
This paper proposes a logistic regression approach paired with term and inverse document frequency (TF*IDF) for Arabic sentiment classification on services' reviews in Lebanon country. Reviews are about public services, including hotels, restaurants, shops, and others. We collected manually from Google reviews and Zomato, which have reached to 3916 reviews. Experiments show three core findings: 1) The classifier is confident when used to predict positive reviews. 2) The model is biased on predicting reviews with negative sentiment. Finally, the low percentage of negative reviews in the corpus contributes to the diffidence of logistic regression model.

Hybrid CNNs LSTM Deep Analyzer for Arabic Opinion Mining
Deep learning models have showed great capabilities in data modelling on natural language processing various applications, including sentiment analysis, part of speech tagging, machine translation, and many others. In particular, convolutional neural network (CNNs) and long term short memory (LSTM) have proved to be effective in capturing longterm dependencies in sequential data that result in state of the art performance in comparison to traditional machine learning algorithms. This research paper, therefore, structures an enhanced model of both CNNs and LSTM for the feature resourcefulness of Arabic text data on freely available benchmark datasets, with word2vec representation model for each corpus. The model is projected for Arabic sentiment analysis (ASA) in highlight. The proposed architecture has achieved better performance on three datasets out of five in comparison to previous studies. In research conduct, the model achieved a total accuracy of 0.881 for Main AHS, 0.968 for Sub AHS, 0.842 for Ar Twitter, 0.7918 for ASTD, 0.903 for OCLAR.

Classifiers for Arabic NLP: survey
In this paper, we reviewed most common used models and classifiers that used for the Arabic language to classify texts into categories, classes, or topics in tasks of opinion mining, sentence categorisation, part of speech tagging, language identification, name entity recognition, authorship attribution, word sense disambiguation, and text classification. Comparisons between classification tasks conducted in terms of models' performances and accuracies. Classification approaches are three types: lexicon based, machine and deep learning, or hybrid ones. Research sample is 34 articles in the classification domain. Challenges facing the Arabic language discussed with further solutions: 1) solid research training on both approaches: lexicon based and corpus based (machine and deep learning) 2) research contribution mainly corpus, approach technique, and free accessibility; 3) fund increase to the research development in the Arab world.

In vitro evaluation of the antibacterial activity of the essential oils of Micromeria barbata, Eucalyptus globulus and Juniperus excelsa against strains of Mycobacterium tuberculosis (including MDR) Mycobacterium kansasii and Mycobacterium gordonae.
BACKGROUND Mycobacterium spp. are responsible for several diseases, particularly in immunocompromised populations. The spreading of the resistance to antimycobacterial drugs is a significant problem to the public health and requires to find out a new and innovative alternative for the treatment of drug resistant mycobacterial strains. In this study, the antimycobacterial activity of Micromeria barbata, Eucalyptus globulus and Juniperus excelsa essential oils extracted from Lebanese plants was investigated against selected Mycobacterium spp. strains. METHODS Several dilutions of the three aforementioned essential oils were studied for antimycobacterial activity against four Mycobacterium spp. strains: Mycobacterium tuberculosis subsp. tuberculosis (ATCC(r) 27294(tm) multidrug resistant M. tuberculosis (CMUL 157) Mycobacterium kansasii Hauduroy (ATCC(r) 12478(tm) and Mycobacterium gordonae Bojalil et al. (ATCC(r) 14470(tm) RESULTS Even with high dilutions, all tested essential oils showed a high antimycobacterial activity against targeted strains. Our data showed that M. barbata, E. globulus and J. excelsa essential oils totally inhibit the mycobacterial growth whatever the tested strains for the dilution 1/250, 1/100 and 1/250, respectively. CONCLUSION To our knowledge, this is the first study regarding the antimycobacterial activity of essential oils in Lebanon. Our data show promising results, and encourage to investigate more on these medicinal plants, especially M. barbata.

First Lebanese Antibiotic Awareness Week campaign: knowledge, attitudes and practices towards antibiotics.
Antibiotic resistance (ABR) is a major global health threat that increases the risk of treatment failure and increases medical costs. One of the most common factors contributing to the spread of ABR is self medication. The public, as well as workers in clinical and veterinary sectors, commit false practices towards appropriate antibiotic use, favouring the spread of resistance. As such, the first Lebanese Antibiotic Awareness Week campaign was initiated with a human centred and interactive approach. The data showed a strikingly low level of antibiotic awareness. Cooperation between relevant stakeholders, policy makers and health actors is crucial to control and overcome the problem of ABR.

Prevalence of Staphylococcus aureus methicillin sensitive and methicillin resistant nasal carriage in food handlers in Lebanon: a potential source of transmission of virulent strains in the community
Purpose To determine the prevalence and virulence determinant genes of nasal colonization by Staphylococcus aureus among food handlers in Tripoli, Lebanon. Methodology Within a cross sectional study design, nasal swab specimens were collected. Epidemiological and microbiological investigations were performed through conventional culture and MALDI TOF MS. Antibiotic susceptibility patterns and genetic virulence determinants including enterotoxin genes were also investigated for all isolates. Results The data herein show that S. aureus nasal carriage is highly prevalent (23.8 and that the rate of methicillin resistant S. aureus (MRSA) carriage was twice as high as in our last report in 2008. Several enterotoxin genes were detected in five isolates including one MRSA and four methicillin sensitive S. aureus Conclusion To our knowledge, this is the first investigation in the last decade to examine the carriage prevalence of S. aureus among food handlers in Lebanon. This work reports a concerning level of MRSA, and enterotoxin producing S. aureus nasal carriage, which could potentially act as a contamination reservoir and lead to food poisoning.

A prosodic account of wh formation in Jordanian Arabic
Abstract This paper shows that wh formation in Jordanian Arabic (JA) is prosodically ruled. Wh words should move either to the left or to the right periphery of the phonological phrase that contains the relevant wh word. What appears as an in situ instance of a wh question in JA, as reported by several studies, is in fact a true instance of a moved wh word but to the right periphery of the phonological phrase that contains the wh word. Movement to either peripheral position is forced by prosodic facts of JA where elements that express or stand for the most prominent information of the question should bear prosodic prominence which falls on either peripheral positions of the phonological phrase containing the wh word. A grammaticality judgment task was carried out to check the frequency of left and right peripheral questions in JA. Fifteen participants (all native speakers of JA) were asked to respond to nine contexts. The results show that the left peripheral option is far more frequent than its right peripheral counterpart (93.8% and 6.2% respectively) The findings of this study make available empirical evidence in favor of Mathieu's (2016) theory of wh formation where prosody is the main factor for wh patterns in natural languages.

Effects of Sucrose based High lysine Diet on Blood Chemistry, Growth Performance, and Gastrointestinal Morphology of Broiler Chickens During the Growing Stage
This study aimed to investigate the effect of replacing fat in broiler grower diet with sucrose combined with supplementation of the synthetic amino acid lysine on growth performance, gastrointestinal morphology, and blood biochemical parameters in broiler chickens. Broilers were raised for 21 days and then divided into two treatment groups (n=24 in each group) Two dietary treatments were used: corn soy based diet with oil (control) and corn soy based diet formulated with sucrose (3.30% and lysine hydrochloride (3.36% The experimental period was 21 days (from 21 to 42 days of age) At the end of week 6, all the birds in each treatment were slaughtered via neck slit, defeathered, and eviscerated for carcass and intestinal morphological characterization. Blood samples were collected to measure blood lipoprotein, triglyceride, and cholesterol levels. The results showed that supplementation of sucrose and lysine hydrochloride to broiler ration significantly (P<0.05) decreased feed intake by half and reduced average daily gain during the study period compared to those observed in broilers fed control diet. Further, this supplementation significantly altered gastrointestinal morphology and blood lipoprotein (HDL and LDL) and total cholesterol levels. In conclusion, corn soy based diet fortified with sucrose (3.30% and lysine hydrochloride (3.36% within current nutrient specifications has a negative effect on broiler growth performance.

RANKING TERRORISTS IN NETWORKS: A SENSITIVITY ANALYSIS OF AL QAEDA'S 9/11 ATTACK By
All over the world intelligence services are collecting data concerning possible terrorist threats. This information is usually transformed into network structures in which the nodes represent the individuals in the data set and the links possible connections between these individuals. Unfortunately, it is nearly impossible to keep track of all individuals in the resulting complex network. Therefore, Lindelauf et al. (2013) introduced a methodology that ranks terrorists in a network. The rankings that result from this methodology can be used as a decision support system to efficiently allocate the scarce surveillance means of intelligence agencies. Moreover, usage of these rankings can improve the quality of surveillance which can in turn lead to prevention of attacks or destabilization of the networks under surveillance. The methodology introduced by Lindelauf et al. (2013) is based on a game theoretic centrality measure, which is innovative in the sense that it takes into account not only the structure of the network but also individual and coalitional characteristics of the members of the network. In this paper we elaborate on this methodology by introducing a new game theoretic centrality measure that better takes into account the operational strength of connected subnetworks. Moreover, we perform a sensitivity analysis on the rankings derived from this new centrality measure for the case of Al Qaeda's 9/11 attack. In this sensitivity analysis we consider firstly the possible additional information available about members of the network, secondly, variations in relational strength and, finally, the absence or presence of a small percentage of links in the network. We also introduce a case specific method to compare the different rankings that result from the sensitivity analysis and show that the new centrality measure is robust to small changes in the data.

Palest inian Succession GHAITH AL OMARI AN OVERVIEW OF INSTITUTIONAL TURMOIL
(c) 2015 The Washington Institute for Near East Policy. All rights reserved. T question of Palestinian succession has persisted for some time, fueled by Palestinian Authority president Mahmoud Abbas's repeated threats of resignation, his advanced age, and the legal expiration of his presidential term in 2009. Recently, a number of measures targeting leading Palestinian political figures and institutions as well as reports pertaining to Abbas's health have added urgency to the succession question. This question, meanwhile, has gained currency amid a continuing Palestinian political crisis. The project of establishing a state has stalled with the stagnation of the Middle East peace process and momentous regional developments that have relegated the Palestinian issue to secondary status. Since 2007, the Palestinian polity has been split politically and geographically between the Fatahdominated Palestinian Authority (PA) which governs the West Bank, and Hamas, which rules over the Gaza Strip. All efforts aimed at achieving national reconciliation have failed. In the meantime, recent polls show that Palestinians do not trust any of their political leaders, parties, or institutions.1 Much of the debate about succession has focused on the PA because it governs Palestinians in the West Bank and, at least de jure, those in the Gaza Strip and serves as the institutional address used by the international community. Yet Abbas, like his predecessor, Yasser Arafat, presides over three related yet distinct Palestinian institutions: the PA, the Fatah movement, and the Palestine Liberation Organization (PLO) Additionally, like Arafat before him, he holds the title of president of the State of Palestine, which while so far merely symbolic has assumed greater prominence since Palestine's 2012 admission as a nonmember observer state to the United Nations. In the fog surrounding succession, one thing is certain: the orderly constitutional mechanism set forth in the PA's 2003 Basic Law, whereby an unexpectedly vacated presidency would be filled by the Palestinian Legislative Council speaker for sixty days followed by elections, will not be implemented. Instead, the successor will almost certainly be chosen by Fatah and need to be confirmed by the PLO. However, Fatah is beset by severe political dysfunction and the PLO's credibility has declined in recent years. While both Arafat and Abbas assumed uncontested leadership of these institutions by virtue of being in the founding generation of Palestinian politics, few if any of the current contenders have the obvious credentials to smoothly succeed Abbas. The complexities presented by current Palestinian politics and the aforementioned institutional overlap have made succession an uncertain and potentially volatile process. Palest inian Succession
