The use and impact of Goodreads rating and reviews, for readers of Arabic books

The focus of this research is to assess how the use of Goodreads can influence Arabic readers' selection of books, to study Arabic reviewers' behaviour and to explore the impact of Goodreads' metrics on book sales. Research methodology of the presented work consisted of a wide review of relevant literature, the collection and analysis of data from a questionnaire and a case study on a list of best-selling Arabic books fetched from two book-review platforms; Goodreads.com and Jamalon.com. The findings of the presented study show that Goodreads metrics reveal highly relevant indicators for books' contents, and consequently have a significant impact on Arab's book-purchasing decisions. Furthermore, we observed that Arabic Goodreads users tend to rate books rather than write reviews, and their book evaluation is mostly based on their contents. Primary research results suggest that, with proper analysis applied, Goodreads is an effective book evaluation network/online community for Arabic readers and Arabic book consumers. It is believed that the effectiveness of the studied network is mainly due to the metrics applied, which appear to be matching evaluation criteria as preferred by Arabic readers.
The effect of Kinesio ª taping space-correction-technique on post-needling soreness in the trapezius muscle trigger point two

Dry needling (DN) fanning technique is an effective treatment for myofascial trigger points (MTP), however, it causes swelling and intramuscular haemorrhage which results in post-needling soreness (PNS). Kinesio ® taping space-correction-technique (KTSCT) is claimed to aid in reducing pain by decreasing inflammation, increasing circulation and lymphatic drainage. This in theory indicates that Kinesio ® taping could reduce/alleviate PNS pain after DN. Objective: The purpose of this study was to determine the effectiveness of KTSCT utilizing Kinesio ® Tex Gold tape in reducing the level of PNS associated with DN a trapezius muscle trigger point two. Method: Forty five patients with active trapezius muscle MTP two were randomly allocated into one of three treatment groups. All groups received a standardized DN treatment. Thereafter, group one received no further treatment and acted as the control group, group two received an application of KTSCT utilizing Kinesio ® Tex Gold tape, while group three received a non-proprioceptive hypoallergenic tape application. Assessments were made pre-, post-treatment and at a follow-up consultation on the following day once the taping application was removed. Assessments included numerical pain rating scale-101 (NRS-101), a pain diary and algometer readings. Results: Group three showed an improvement over the control group, however, it was not a statistically significant improvement in any of the assessments. Group two showed statistically significant improvement over the control in the pain diary and algometer readings overall. Results from the NRS-101, showed that group two had a statistically significant improvement when compared to the control group over the time interval when the Kinesio ® Tex Gold tape was applied to the patient. Conclusion: KTSCT utilizing Kinesio ® Tex Gold tape had a greater effect in reducing the level of PNS associated with DN a trapezius muscle trigger point two, when compared with either a non-proprioceptive hypoallergenic tape application or a control group.

The aim of this paper is to survey the different machine learning techniques employed within the scope of discovering the hateful language on social networking site, their challenges to provide a solution to detect the toxic comment and modify it of the same.
Improved Modulation Strategy for Single-Phase Single-Stage Isolated AC–DC Converter Considering Power Reversion Zone

In this article, an improved modulation strategy for the single-phase single-stage isolated bidirectional ac–dc converter is proposed. The modulation of ac side cycloconverter is based on the unipolar idea to reduce the switching quantity and the ac side current ripple and provide the bidirectional current flow path. The dc side H-bridge converter is driven by the pulsewidth modulation signals cooperatively to speed up the transformer current and thus to eliminate the voltage spike. Furthermore, the power reversion zone (PRZ) of the converter is verified. The action of the proposed modulation strategy in PRZ is analyzed for the first time. It reveals that the reverse current overshoot is caused in ac-to-dc direction and the voltage spike is caused in dc-to-ac direction. An online switching scheme of the proposed modulation strategies in two power directions is proposed to solve these problems. The detailed experimental results verify the correctness and reliability of the proposed modulation strategy.
On the Melting Process of the Phase Change Material in Horizontal Rectangular Enclosures

Phase change material (PCM) is one of the most important ways to store and manage energy. The melting process of PCM in a rectangular enclosure with the different aspect ratio is frequently related to some thermal energy storage devices. In this work, the melting of PCM in the horizontal rectangular enclosures heated from the different sides and the influence of aspect ratio of the rectangle are carefully studied. The enthalpy porosity technique and the finite volume method (FVM) are used to simulate the melting process numerically. The results show that the melting process of PCM can be dominated by conduction or natural convection due to the different heated sides. The melting of PCM in the enclosure heated from the bottom side is firstly affected by conduction and then mostly influenced by convection. In addition, the aspect ratio of the rectangular enclosure is found to play an important role in the melting process. Finally, a series of fitting correlations of the liquid fraction, Nusselt number and the energy storage are presented with the influence of aspect ratios in order to provide the reference for designing the rectangular container of PCM. This study is helpful for the selection of an appropriate aspect ratio and heating method to achieve the desired energy storage performance of encapsulated PCM.
Fluctuation of PV array global maximum power point voltage during irradiance transitions caused by clouds

In well-designed photovoltaic (PV) power plants, such as in typical utility-scale PV plants, operational conditions are quite stable and homogeneous apart from the fast irradiance transitions caused by cloud shadings. These partial shading events cause fast power fluctuations leading even to stability and quality problems in power networks. Fast non-homogeneous irradiance transitions cause also mismatch losses in PV generators and the occurrence of multiple maximum power points (MPPs), which appear in a wide voltage range of the PV generator. In consequence, the global MPP can fluctuate in a wide voltage region causing possible MPP tracking problems and power losses. This article presents a study of the behaviour of the global MPP voltage of various PV arrays during irradiance transitions caused by clouds. The global MPP voltage, its rate of change and the differences in voltage and available energy between the global MPP and the MPP with the highest voltage of the PV generators have been analysed comprehensively, for the first time, by using the characteristics of around 8000 measured irradiance transitions. The global MPP voltage was found to vary between 28 and 112% of the nominal MPP voltage of the array.
Maintenance and Repair Work

ABSTRACT This essay review evaluates recent contributions in the field of maintenance and repair studies with a focus on a special issue of Tecnoscienza on this research field and a volume edited by Ignaz Strebel, Alain Bovet, and Philippe Sormani entitled Repair Work Ethnographies: Revisiting Breakdown, Relocating Materiality. These two publications provide important insights into empirical investigations of maintenance and repair work which raise stimulating questions for engineering studies, where these activities are often overlooked.
Study of The Phenomena of Surface Discharges and Flashover in Nanocomposite Epoxy Resin under the Influence of Homogeneous Electric Fields

A new class of insulating materials is the class of polymer nanocomposites. In the past twenty-five years, a lot of attention was paid to the various electrical, thermal and mechanical properties of polymer nanocomposite materials. In the present work, epoxy resin samples without and with nanoparticles (0 wt%, 1 wt%, 3 wt%, 5 wt%, and 10 wt%) are investigated regarding the surface discharges and the flashover voltages. Four different water droplet arrangements were used, with eight different water conductivities in order to see the effect of the nanoparticle.
Learning from On-Line User Feedback in Neural Question Answering on the Web

Question answering promises a means of efficiently searching web-based content repositories such as Wikipedia. However, the systems of this type most prevalent today merely conduct their learning once in an offline training phase while, afterwards, all parameters remain static. Thus, the possibility of improvement over time is precluded. As a consequence of this shortcoming, question answering is not currently taking advantage of the wealth of feedback mechanisms that have become prominent on the web (e. g., buttons for liking, voting, or sharing). This is the first work that introduces a question-answering system for (web-based) content repositories with an on-line mechanism for user feedback. Our efforts have resulted in QApedia - a framework for on-line improvement based on shallow user feedback. In detail, we develop a simple feedback mechanism that allows users to express whether a question was answered satisfactorily or whether a different answer is needed. Even for this simple mechanism, the implementation represents a daunting undertaking due to the complex, multi-staged operations that underlie state-of-the-art systems for neural questions answering. Another challenge with regard to web-based use is that feedback is limited (and possibly even noisy), as the true labels remain unknown. We thus address these challenges through a novel combination of neural question answering and a dynamic process based on distant supervision, asynchronous updates, and an automatic validation of feedback credibility in order to mine high-quality training samples from the web for the purpose of achieving continuous improvement over time. Our QApedia framework is the first question-answering system that continuously refines its capabilities by improving its now dynamic content repository and thus the underlying answer extraction. QApedia not only achieves state-of-the-art results over several benchmarking datasets, but we further show that it successfully manages to learn from shallow user feedback, even when the feedback is noisy or adversarial. Altogether, our extensive experimental evaluation, with more than 2,500 hours of computational experiments, demonstrates that a feedback mechanism as simple as a binary vote (which is widespread on the web) can considerably improve performance when combined with an efficient framework for continuous learning.
Is There a Relationship Between Performance During Physical Therapist Clinical Education and Scores on the National Physical Therapy Examination (NPTE)?

Background and Purpose. The determination of whether a student physical therapist (PT) has reached entry‐level status for graduation purposes is partially determined by the physical therapist education program's evaluation tool used for rating student performance in the clinical setting. The determination of whether a graduate can practice physical therapy depends on graduate performance on the National Physical Therapy Examination (NPTE). Clinical performance as assessed by the clinical evaluation tool used by members of the Texas Consortium for Physical Therapy Clinical Education (Consortium), the Physical Therapist Manual for the Assessment of Clinical Skills (PT MACS), has not been evaluated with regard to the NPTE. Therefore, the purposes of this study were to assess the following: (1) the relationship between PT MACS section scores on the first and final clinical experiences with section scores on the NPTE among first‐time test takers, (2) the relationship between PT MACS aggregate scores on the first and final experiences with the overall score on the NPTE among first‐time test takers, and (3) the relationship of final PT grade point averages (GPAs) with NPTE scores among first time test takers. Subjects/Methods. This retrospective study used archived academic, clinical, and NPTE performance data collected by the directors of Clinical Education of 8 Texas PT professional education programs for classes graduating between 2004 and 2007. The total number of graduates was 985. Data were analyzed for relationships using Pearson product moment correlation coefficients. Results. Small, but significant, relationships were found between 2 PT MACS sections and corresponding sections on the NPTE (P < .01). A small correlation was identified between the PT MACS visual analog scale (VAS) ratings and the NPTE score (P < .001). Despite these associations, PT GPA still had the largest correlation with NPTE scores (P < .001). Further investigation indicated high interitem correlation in the PT MACS sections used in the correlation with NPTE sections, indicating good reliability of the PT MACS skills. Cronbach alpha scores ranged from . 63 to . 86. Discussion and Conclusion. Althoughseveral small, significant relationships were found between the PT MACS sections and corresponding NPTE sections, PT GPA demonstrated the greatest relationship with success on the NPTE, reinforcing the findings of previous studies. Based on results of the inter‐item analysis, the PT MACS demonstrated good internal consistency reliability. Results of this study suggest that an assessment tool that tests all domains of learning cannot predict performance on a cognitive instrument such as the NPTE.
Job Satisfaction Among Family Nurse Practitioners in the United States Air Force

Abstract : Increasing numbers of Family Nurse Practitioners (FNPs) are being utilized within the Air Force. Nurse Practitioners provide patient education, acute care, and prevention services at lower cost due to the lower cost of training and lower salaries than physicians, without jeopardizing care. Creating an optimal working relationship, can help the new FNP integrate into their new role successfully. The purpose of this descriptive study is to describe and assess the factors affecting job satisfaction among FNPs in the Air Force. The conceptual framework to guide this study is based on Frederick Herzbergs theory of job satisfaction. Identifying the factors affecting job satisfaction, can help team members, supervisors and the new FNPs smoothly transition to the provider role. The entire population of 32 Air Force FNPs were surveyed using the Measurement of Job Satisfaction tool developed by Traynor and Wade. The 44 item tool contains questions related to seven categories: personal, workload, training, standards of care, pay, prospects, and professional support satisfaction. A 5 point Likert scale was used to measure the FNPs responses to each of these categories. Descriptive statistics were used to analyze the demographic data of the subjects regarding age, education, rank, education, clinical setting and years of practice. Study results show that overall Air Force FNPs express a high level of satisfaction. As earlier literature demonstrates, intrinsic factors such as personal satisfaction and quality patient care positively influence job satisfaction. Also salary was found to be the highest dissatisfier. Study results may be helpful to supervisors and FNPs as the role of Nurse Practitioners expand in the Air Force.
Coordinated Sequential Control of Individual Generators for Large-Scale DFIG-Based Wind Farms

To enhance the Low-voltage Ride Through (LVRT) capability of large-scale centralized wind farms is essential for the safety of the wind farm and the security of the power system. However, the LVRT capability enhancement coordinating the control and protection of individual wind generators merits consideration. To contribute in this way, a Coordinated Sequential Control (CSC) strategy is proposed in this manuscript. Regarding different voltage disturbance scenarios, the goal of voltage control is determined in real-time. To keep as many wind turbines operating grid-connected as possible, a multi-staged coordination strategy is set according to the critical time to ride through the fault. The reactive power control and the shedding of the wind turbines are coordinated in the three stages of the CSC. According to the simulation results, more wind turbines can be kept grid-connected by using the proposed control strategy. Comparison studies are made among several types of coordinating strategies, emphasizing the advantages of the proposed method in terms of both validation and real-time performance.
Feasibility of a Quasi-Static Approach in Assessing Side-Wind Hazards for Running Vehicles

This study is an examination into the feasibility of a quasi-static approach to evaluating the reaction forces that impact tires. This information could lend valuable insight into efforts to limit overturning and side-slip accidents of vehicles exposed to strong side winds. The performance of the quasi-static approach was evaluated by comparing the calculated tire forces with those created using TruckSim, which is a dynamic vehicle analysis software. Governing equations were formulated for two types of vehicles that are susceptible to the force of wind, vans, and trailers, by considering a force equilibrium, a compatibility condition, and several assumptions. The quasi-static approach for trailers is a novel expansion of the conventional approach to a two-axle vehicle. Proposed enhancements to the quasi-static approach reflect the additional rolling moment of a trailer. The curvature and the cant of a curved road were accounted for via centrifugal forces. Both uniform and turbulent wind conditions were considered in questioning the feasibility of this novel approach.
Assessment of Performance of Fiber Reinforced Geopolymer Composites by Experiment and Simulation Analysis

In this work, the experimental and simulation analysis of the performance of geopolymer composites reinforced with steel fiber and polypropylene fiber is investigated. By embedding hooked end steel fiber and polypropylene fiber with various volume fractions of 0%, 0.5%, 1%, 1.5% to the geopolymer concrete mixture, the mechanical behavior was enhanced significantly through experimental results. The compressive strength was improved 26% with 0.5% of polypropylene fiber and 46% with 1% of hooked end steel fiber while the increment of splitting tensile strength was 12% and 28%, respectively. The flexural strength of specimens using two fiber types was also improved when compared with the non-fiber geopolymer concrete. The highest increment obtained with 1.5% of fiber volume content was from 26% to 42%. The compressive performance and flexural performance of fiber-reinforced geopolymer concrete were also better than specimens without fiber, with a higher load carrying capacity, higher stress, higher toughness and smaller strain. Using hooked end steel fiber resulted in better mechanical strength than using polypropylene fiber, and the presence of fibers is an important factor related to the strength improvements. A finite element analysis was modeled by the ANSYS program, and this showed that the load–deflection response and crack patterns also agreed quite well with experimental results.
Who follows whom? A coincidence analysis of military action, public opinion and threats

Does public opinion act as a constraint on military action, are ordinary citizens the easily manipulated targets of the public relations efforts of their governments, or does the general public react as assertively to threats as decisionmakers? This article examines the causal connection between military action, public opinion and threats. Empirically, it focuses on the pattern of EU member state participation in two recent military operations: the 2011 intervention in Libya and the operation against the self-proclaimed Islamic State (IS). Three competing causal models on the relationship between threats, public opinion and military action were derived from the scholarly literature and tested with coincidence analysis. The results of the analysis show that public opinion acted as a constraint on executives during the Libya operation. However, there was no direct causal link between public opinion and military participation in the operation against IS, in which both military action and public support were an effect of threat. More generally, the results suggest that the context of the intervention is decisive for the relation between threat, military action and public support. More specifically, whether public opinion constitutes a constraint on military action or is an effect of threats to national interests depends on whether these threats are clear and tangible.
Analysis of upper-limb movements to open glass ampoules and training methods in nursing education

An ampoule is a glass cylinder that contains intravenous solutions. Ampoule opening (AO) is performed by nurses on a daily basis, but the procedure involved can cause injuries to the hand as well as contamination of ampoule contents with glass microparticles. As it is currently impossible to completely eliminate the use of glass ampoules, one should learn how to safely perform the AO operation. Herein, we quantitatively analyze the combined seven upper-limb movements of ten experienced participants to clarify the mechanism of AO operations and establish a procedure for safe AO. Unlike current instruction manuals, this study focuses on the joint movements of dominant and nondominant upper limbs rather than on finger positions. A motion-capture system and video cameras are used to analyze the above seven movements of each upper limb. Based on results obtained, the following three guidelines for performing AO operations are derived: (1) supinate the elbow joint to break the ampoule neck; (2) move the dominant hand away from the cutting plane of the ampoule immediately after ampoule breaking without moving the nondominant hand to avoid unnecessary contact of fingers with the cutting plane; (3) synchronize elbow-joint extension with supination in step (1) as the dominant hand is moved away after ampoule breaking. This approach not only ensures safe AO but also helps in learning other skills related to technical nursing education.
The Impact of Space-Based AIS Antenna Orientation on In-Orbit AIS Detection Performance

In this paper, a study on the impact of changing the space-based Automatic Identification System (AIS) monopole antenna orientation on its message reception performance in orbit has been conducted. The study has been carried out by maneuvering the attitude of LAPAN-A2, an equatorial orbiting microsatellite with AIS antenna fixedly mounted on the satellite’s body, into the desired orientation. Based on the analysis of the datasets collected during the maneuver, the orientation of AIS monopole antenna 45° toward its flight direction increases the overall detection performance of the AIS message, including class A ship to 208.80% and also class B ships to 175.93%. This orientation also increases the detection of AIS messages in ocean areas having low detection probability due to AIS signal collision. The result of this research could become a reference in order to specify AIS antenna position and orientation in a small satellite carrying a space-based AIS system for maritime surveillance & monitoring purposes.
