Evaluating the reasons of low reading skills of primary school students and the activities used by teachers<p>İlkokul öğrencilerinin düşük okuma başarısının nedenlerinin ve öğretmenlerin kullandığı etkinliklerin değerlendirilmesi
Authors: Çakıroğlu Orhan 
Published: April 2015

<p>Reading skill is one of the most important skills in someone’s educational life. Although reading skill has such an importance, there are limited research studies that investigate reading achievement of students with low reading skills and factors that their teachers believe that cause low reading achievement. Specifically, there is no research study that investigates reading success around Turkey. The purpose of this study is to investigate the activies that primary school teachers and special education teachers use in their classrooms and opinions of these teachers regarding their students’ reading success. According to the findings, most students in our primary schools have poor reading skills. Teachers believe that the main reasons for poor reading skills are the student himself and parents’ negative attitudes. Also, the most used activies by teachers are asking parents to help their children and spending more individual time with students during reading studies.</p><p> </p><p><strong>Özet</strong></p><p>Okuma becerisi bireyin eğitim yaşamında en önemli yere sahip becerilerin başında gelmektedir. Okuma becerisinin bu derece büyük öneme sahip olmasına rağmen ilkokul öğrencilerinin okuma başarısını değerlendiren ve ilkokul öğretmenlerinin düşük okuma başarısının nedenleri olarak gördükleri faktörlerin tespitine yönelik çalışmalar sınırlı sayıdadır. Özellikle Türkiye genelini kapsayan herhangi bir çalışmaya alanyazında rastlanmamıştır. Bu çalışmanın temel amacı, ülkemizdeki sınıf ve özel eğitim öğretmenlerinin sınıflarındaki öğrencilerin okuma başarılarını artırmaya yönelik yaptıkları etkinliklerin türünü, sıklığını ve bu öğretmenlerin öğrencilerinin okuma performanslarına yönelik görüşlerinin belirlenmesidir. Araştırma sonuçlarına göre, ilkokul sınıflarındaki öğrencilerimizin büyük bir çoğunluğunun okuma başarısı ortalamanın altındadır. Öğretmenler düşük okuma başarısının en önemli nedenleri olarak öğrencinin kendisini ve ailenin olumsuz tutumlarını görmektedir. Ayrıca, öğretmenlerin en sık kullandıkları etkinlikler ailelerden öğrencilere okuma becerilerinde yardımcı olmalarını istemek ve öğrenciyle okuma çalışmalarında bireysel olarak çok zaman harcamadır.</p>
Social Enterprise Innovation in Context: Stakeholder Influence through Contestation
Authors: Newth Jamie 
Published: April 2015

AbstractSocial enterprises are the products of the social, cultural, commercial, and political expectations of the innovation’s range of stakeholders, not solely the vision of the social entrepreneur(s). The power of stakeholders to influence the development of an innovation is drawn from their salience and the resources, access, and/or legitimacy that their support would provide. In this way, the actions of social entrepreneurs represent the interests of communities and it is through processes of resistance, negotiation, and collaboration that the actions of social enterprises become the manifestations of collective social processes. This paper draws on the development of a nascent social enterprise in New Zealand to demonstrate how the effects of its context ultimately shaped its innovative business model. Using an ethnographic methodology, the development of the business model and the partnership through which it formed was examined by the author as a central actor as it unfolded. The case study serves as an illustrative example of the ways in which differing expectations, beliefs, and logics of stakeholders induces particular decisions to be made about the design, resourcing, and strategy of the venture.
Plagiarism Detection Using Machine Learning-Based Paraphrase Recognizer
Authors: Chitra A. , Rajkumar Anupriya 
Published: April 2015

AbstractPlagiarism in free text has become a common occurrence due to the wide availability of voluminous information resources. Automatic plagiarism detection systems aim to identify plagiarized content present in large repositories. This task is rendered difficult by the use of sophisticated plagiarism techniques such as paraphrasing and summarization, which mask the occurrence of plagiarism. In this work, a monolingual plagiarism detection technique has been developed to tackle cases of paraphrased plagiarism. A support vector machine based paraphrase recognition system, which works by extracting lexical, syntactic, and semantic features from input text has been used. Both sentence-level and passage-level approaches have been investigated. The performance of the system has been evaluated on various corpora, and the passage level approach has registered promising results.
Research on the Selection of Geosynthetics for Infrastructure Works
Authors: Chirică Raluca Ioana 
Published: April 2015

Rezumat
Materialele geosintetice sunt utilizate la scară largă în lucrările de infrastructura transporturilor şi protecţia mediului.
Armăturile din geosintetice permit realizarea unor lucrări inginereşti dificile şi chiar imposibil de realizat, cum ar fi execuţia de terasamente pe terenuri slabe sau foarte slabe de fundare sau construcţia de lucrări de susţinere complexe.
Interacţiunea geosintetic - pământ (frecarea între feţe şi/sau caracteristicile de încleştare) reprezintă un element cheie ce joacă un rol important în cazul structurilor din pământ armat sau în alte aplicaţii unde este importantă rezistenţa materialului geosintetic la alunecare sau smulgere.
De asemenea, fluajul sub acţiunea încărcărilor de lungă durată reprezintă una dintre cele mai importante proprietăţi a materialelor geosintetice utilizate ca armături. Încercarea la fluaj permite stabilirea duratei de exploatare a lucrărilor care înglobează materiale geosintetice.
Încercările efectuate pe materialele geosintetice trebuie să fie în conformitate cu cerinţele unei anumite aplicaţii practice şi să aibă ca scop comun alegerea celei mai potrivite soluţii. De exemplu, în cazul unei lucrări de armare a unui masiv de pământ, este necesară atât cunoaşterea caracteristicilor de tip efort - deformaţie ale materialului geosintetic utilizat, cât şi determinarea parametrilor de interacţiune pământ-material geosintetic.
În lucrare se prezintă încercările de performanţă efectuate pentru ansamblul pământgeogrilă în cadrul acestui studiu, precum şi rezultatele obţinute şi concluzii privind utilizarea geogrilelor în cadrul lucrărilor de îmbunătăţire a caracteristicilor pământului. Este evidenţiat rolul unei selecţii corecte a materialului geosintetic care urmează a fi utilizat pentru lucrări de pământ armat.

Controllable Nonautonomous Rogue Waves in the Modified Nonlinear Schrödinger Equation with Distributed Coefficients in Inhomogeneous Fibers
Authors: Wang Lei , Zhang Lu Lu , Qi Feng-Hua 
Published: March 2015

Abstract
Under investigation in this paper is an inhomogeneous modified nonlinear Schrödinger (MNLS) equation describing the ultrashort pulse dynamics with the distributed dispersion, self-phase modulation, self-steepening, and linear gain/loss. Nonautonomous rogue waves for the inhomogeneous MNLS equation are constructed via the modified Darboux transformation with the inhomogeneous parameters. The dynamical behaviours and main characteristics of the nonautonomous rogue waves in inhomogeneous fibers are discussed by analysing certain physical quantities. The inhomogeneous effects on the evolution of rogue waves are considered by virtue of the presented rational solutions with distributed coefficients. It is found that the group velocity dispersion (GVD) and linear gain/loss coefficients have effects on the trajectories and amplitudes of the rogue waves, respectively. Additionally, an intriguing composite rogue wave of the inhomogeneous MNLS equation is revealed, owing to the proper choice of the GVD coefficient. Our results could be useful for controlling the rogue waves in the dispersion-managed fiber system.
Ammonia Dissociation on Graphene Oxide: An Ab Initio Density Functional Theory Calculation
Authors: Huang Liangliang , Gubbins Keith E. 
Published: March 2015

Abstract
Interactions of ammonia and water with the oxygen-containing
functional groups of graphite oxide have been studied by ab
initio density functional theory method. The results show that
ammonia can dissociate on the carboxyl, epoxy and hydroxyl groups. The
dissociation on the epoxy group is an exothermic reaction with a small
activation energy barrier. Water is found to form a hydrogen bond with
the carboxyl, epoxy and hydroxyl groups, and thus will block ammonia
from interacting with those functional groups. The results in this
work provide a fundamental understand of previous experiments about
ammonia adsorption on graphene oxide materials.
Vacuum Pluviation Device for Achieving Saturated Sand

Published: April 2015

Abstract
Saturation of sand specimens during experimental investigations is important to correctly reproduce undrained shearing behavior, including liquefaction. Sand below the water table is often well saturated in situ because any gases trapped during deposition or compaction have had adequate time to dissolve or migrate through the sand. Reproducing this condition on a short time scale in the laboratory often requires use of backpressure or vacuum saturation. However, backpressure and vacuum saturation sometimes cannot be utilized, for example, in centrifuge models containing soils sensitive to the effects of vacuum. This paper focuses on development and validation of a water pluviation device to construct saturated sand levees during a centrifuge testing program for which backpressure and vacuum methods could not be utilized. P-wave velocity, Vp, measurements using an ultrasound system verified the degree of saturation achieved in the fill. Correlations between Vp and B values are discussed. The vacuum saturation system is shown to provide a high degree of saturation (Vp &gt; 1500 m/s), whereas more traditional water pluviation techniques are shown to produce unsaturated fill.

Abstract
To reduce the danger due to uneven surfaces because of manholes, lowering manholes into road structures is a good approach to maintain the serviceability of the pavement. However, the vast expanse of road systems quite increases the complexity of manhole identifications when implementing maintenance and rehabilitation (M&R) activities. Hence, an emerging method for finding manholes beneath pavements is needed. In this study, radio frequency identification (RFID) technology is used to identify manholes beneath pavements. RFID tags with cement blocks were buried in dense-grade asphalt concrete at different depths in a metal mold and then were identified using RFID in the laboratory. This study developed an easy-to-use program on an RFID reader to identify RFID tags on-site. The RFID tags attached to covers of manholes beneath pavements can be easily monitored by the program. Augmented reality (AR) technology can aid users in manipulating virtual objects in real environments. This study developed a mobile manhole monitoring system (MMS) and a web-based MMS. The location and information of manholes can be transmitted from the web-based MMS through the Internet and be shown on the mobile MMS based on the AR technology. The time and costs of manhole identification can be significantly decreased and pavement maintenance activities may be implemented in a more timely fashion by using RFID and AR technologies.
A Proposal to Characterize the Angular Speed and Acceleration of the Torsional Recovery of a Polymer-Modified Asphalt Binder Incorporating Synthetic Wax
Authors: Jamshidi Ali , Hamzah Meor Othman , Hosseinpour Mehdi 
Published: March 2015

Abstract
The objective of this study is to propose a simple methodology based on the Newtonian mechanics or classic kinematic laws for the characterization of the average torsional recovery speed (ω) and the torsional recovery acceleration (ώ) of a polymer-modified asphalt binder incorporating a type of synthetic wax as a warm mix additive. The correlation of the rheological properties of the modified binder in terms of the torsional recovery (TR), along with the engineering properties of prepared warm mixture asphalt in terms of resilient modulus (MR) and indirect tensile strength (ITS), were evaluated. The results indicated that TR, ω, and ώ of the asphalt binders increase as the synthetic wax content increases. The results also indicated that TR, ω, and ώ have strong correlations with rutting factor (G*/sin δ), non-recoverable creep compliance (Jnr), and recovery percentage (R) of the asphalt. Moreover, there is a significant relationship between the parameters of TR, ω, and ώ and the engineering properties of the mixture samples, irrespective of the construction temperatures.
Robust Cooperation in Mobile Ad Hoc Networks
Authors: Krzesinski Anthony 
Published: April 2015

Consider a mobile ad hoc network where the nodes belong to different authorities. The nodes must be given incentives to spend their resources (battery power and transmission bandwidth) in forwarding packets that originate at nodes belonging to another authority. This can be done by assigning a credit balance to each node: when a node acts as an originating node it uses its credits to pay for the costs of sending its own traffic; when a node acts as a transit node it earns credits by forwarding traffic from other nodes.This paper presents a credit-based incentive scheme which assists nodes when they lack the credits necessary to transmit their data. An essential part of the credit-based scheme is a decentralised credit redistribution mechanism to destroy (create) credit at nodes that are over (under) supplied with credit.The goal of this paper is to investigate the effect of various fraudulent activities on the performance of the credit-based incentive scheme. We show that the credit-based scheme is inherently robust with respect to a number of fraudulent activities, provided the nodes behave in a rational manner. We show that credit redistribution is the main reason why the credit-based incentive scheme is relatively immune to fraud.

Published: March 2015

Background:The acquisition of social and emotional skills is associated with positive youth development, character education, healthy lifestyle behaviours, reduction in depression and anxiety, conduct disorders, violence, bullying, conflict, and anger. School-based interventions aimed to enhance these skills go beyond a problem-focused approach to embrace a more positive view of health; they could also improve the youth’s wellbeing.Aim:To describe the main features and to establish the effectiveness of universal school-based RCTs for children and the youth, aimed to promote their psychosocial wellbeing, positive development, healthy lifestyle behaviours and/or academic performance by improving their emotional and social skills.Methods:Systematic review by searching for relevant papers in PubMed/Medline with the following key words: “mental health” OR “wellbeing” OR “health promotion” OR “emotional learning” OR “social learning” OR “emotional and social learning” OR “positive youth development” OR “life skills” OR “life skills training” AND “school”. Interval was set from January 2000 to April 2014.Results:1,984 papers were identified through the search. Out of them 22 RCTs were included. While most interventions were characterized by a whole-school approach and SAFE practices, few studies only used standardized measures to assess outcomes, or had collected follow-up data after ≥ 6 months. The results of all these trials were examined and discussed.Conclusion:Universal school-based RCTs to enhance emotional and social skills showed controversial findings, due to some methodological issues mainly. Nevertheless they show promising outcomes that are relatively far-reaching for children and youth wellbeing and therefore are important in the real world.

Introduction:
Environmental factors can play a role in the pathogenesis of Alzheimer’s disease. We present a case of the simultaneous onset of Alzheimer’s disease in two middle aged adults.

Case presentation:
A married couple ages 54 year and 51-year-old female cohabiting together were diagnosed with Alzheimer’s disease within the same year. The patient’s both developed cognitive decline shortly after a major renovation of their property and followed a similar disease course. The diagnosis was supported by clinical presentation and tissue pathology on autopsy.

Conclusion:
Environmental factors may play a role in the pathogenesis of Alzheimer’s disease. Further understanding of the disease cascade is required.
Vibrational Properties of Sundatang Soundboard

Published: March 2015

Abstract
This paper presents the measurement of vibrational properties of sundatang soundboard. Sundatang is a plucked stringed traditional musical instrument that is popular among the Kadazandusun communities in Sabah, Malaysia. The vibrational properties of the soundboard are measured using CADA-X impact hammering system in a condition where the instrument is without any string. There are two types of sundatang used in this study; one made from acacia and the other from vitex wood. In this measurement, frequency response functions (FRFs) and modal parameters of the top plate and back plate of this instrument are obtained. It is found that in free edge, fundamental frequency of both plates of acacia sundatang is greater than the vitex sundatang in a range of 112 Hz to 230 Hz. However, in clamped edge (attached to its ribs), it was modified to a lower frequency and closer to each other in the range of 55 Hz to 59 Hz. Another finding is the detection of the excitation of similar mode shape at different resonance frequencies. This phenomenon is termed as Different State of Mode (DSM) which is observed may be because the number of testing points is not enough. Findings of this study provide important information to the study of quality development of this instrument
Verification of the Calculation Assumptions Applied to Solutions of the Acoustic Measurements Uncertainty
Authors: Batko Wojciech , Bal Renata 
Published: March 2015

Abstract
The assessment of the uncertainty of measurement results, an essential problem in environmental acoustic investigations, is undertaken in the paper. An attention is drawn to the - usually omitted - problem of the verification of assumptions related to using the classic methods of the confidence intervals estimation, for the controlled measuring quantity.
Especially the paper directs attention to the need of the verification of the assumption of the normal distribution of the measuring quantity set, being the base for the existing and binding procedures of the acoustic measurements assessment uncertainty. The essence of the undertaken problem concerns the binding legal and standard acts related to acoustic measurements and recommended in: 'Guide to the expression of uncertainty in measurement' (GUM) (OIML 1993), developed under the aegis of the International Bureau of Measures (BIPM). The model legitimacy of the hypothesis of the normal distribution of the measuring quantity set in acoustic measurements is discussed and supplemented by testing its likelihood on the environment acoustic results.
The Jarque-Bery test based on skewness and flattening (curtosis) distribution measures was used for the analysis of results verifying the assumption. This test allows for the simultaneous analysis of the deviation from the normal distribution caused both by its skewness and flattening. The performed experiments concerned analyses of the distribution of sound levels: LD, LE, LN, LDWN, being the basic noise indicators in assessments of the environment acoustic hazards.
Active Noise Control Using a Fuzzy Inference System Without Secondary Path Modelling
Authors: Kurczyk Sebastian , Pawelczyk Marek 
Published: March 2015

Abstract
For many adaptive noise control systems the Filtered-Reference LMS, known as the FXLMS algorithm is used to update parameters of the control filter. Appropriate adjustment of the step size is then important to guarantee convergence of the algorithm, obtain small excess mean square error, and react with required rate to variation of plant properties or noise nonstationarity. There are several recipes presented in the literature, theoretically derived or of heuristic origin.
This paper focuses on a modification of the FXLMS algorithm, were convergence is guaranteed by changing sign of the algorithm steps size, instead of using a model of the secondary path. A TakagiSugeno-Kang fuzzy inference system is proposed to evaluate both the sign and the magnitude of the step size. Simulation experiments are presented to validate the algorithm and compare it to the classical FXLMS algorithm in terms of convergence and noise reduction.
