The Role of a Learner Engagement Manual in the Dynamics of the Language Classroom

This study addresses the pressing need of engaging learners of English as a foreign language at basic education level in meaningful learning experiences. It investigates the role of a learner engagement manual on classroom dynamics. The researcher designed a learner engagement manual and trained twenty pre service teachers at the College of Education and Basic Sciences at Ajman University of Science and Technology on using it at practical training schools. An observation sheet was applied before the training on the manual. It was later applied to the same classrooms after the training. Descriptive statistics such as means, standard deviation and Wilcoxcon equation using the SPSS Version 20 were used to measure the effectiveness of the manual. Results show that the learner engagement manual helps both teachers and learners create an entertaining, dynamic and engaging classroom. These results have an implication for curriculum developers, teachers and test developers for involving learners as active participants in all aspects of the teaching learning process.
Isolation, Identification and Screening of Potential Probiotic Bacteria in Milk from South African Saanen Goats
Venue: Probiotics and Antimicrobial Proteins

This study aimed to evaluate lactic acid bacteria isolates from Saanen goats' milk for probiotic attributes, thereby determining their potential as direct fed microbials for goats. Isolates were identified using API 50CH system, 16S rDNA sequencing and matrix assisted laser desorption ionization time of flight mass spectrometry. All 17 isolates obtained were identified as Lactobacillus plantarum except one identified as Pediococcus acidilactici. Four isolates identified as L. plantarum (Accession numbers KJ026587.1, KM207826.1, KC83663.1 and KJ958428.1) by at least two of the techniques used and isolate 17 differently identified by all the methods used were selected as representatives and then screened for probiotic properties. These isolates displayed phenotypic probiotic attributes including tolerance to acid and bile salts, ability to adhere to intestines and possession of antagonistic activities against Proteus vulgaris, Staphylococcus aureus, Salmonella typhimurium, Pseudomonas aeruginosa and Escherichia coli. The lactic acid bacteria isolated from Saanen goats' milk showed potential to be used as sustainable probiotics in goats' industry. Successful use of probiotics in animals depends upon availability of appropriate isolates originating from the specific host animal. This study is a positive contribution towards identification of isolates with potential for formulation as direct fed microbials for South African Saanen goats.
Maximum Entropy Analysis of Hydraulic Pipe Flow Networks

AbstractA maximum entropy (MaxEnt) method is developed to predict mean external and internal flow rates and mean pressure gradients (potential differences) in hydraulic pipe networks, without or with sufficient constraints to enable a closed form solution. This substantially extends existing methods for the analysis of flow networks (e.g. Hardy Cross) applicable only to deterministic networks. The analysis is based on a continuous relative entropy defined on the space of flow rates, requiring one dimension for each edge and node within the network. This entropy is maximized subject to observable constraints on the mean values of certain flow rates and/or potential differences, and also physical constraints arising from Kirchhoff's first and second laws (node and loop constraints) and the frictional properties of each pipe. A semianalytical and numerical algorithm is developed to solve the equation system, which involves implicit solution of multidimensional integrals and root finding with quasi Newton a.
Interlaminar Fracture toughness in Glass Cellulose Reinforced Epoxy hybrid composites

Laminates of fibre reinforced compositesare weak in through thicknessbut strong in fibre direction, this lead to development of hybridizationconcept in polymer composites. In this work a new method of disperssing cellulose micro particleson unidirectional (UD) Glass fibre epoxy composite using semi automated draw down coating technique was adopted to enhance fracture toughness.Test results show that by adding cellulose increases the load carrying competency by 32% in mode I as compare to Glass Epoxy composite samples. Imrovement in interlaminar critical energy release rates (GiC and GnC) up to 55% in Mode I and 19 %in Mode II respectively was also observed. This enahancement in fracture toughnees is due to the amount of fiber bridging seen during crack initiation and propagation.
Use of Performance Enhancing Substances
Venue: Pediatrics

Performance enhancing substances (PESs) are used commonly by children and adolescents in attempts to improve athletic performance. More recent data reveal that these same substances often are used for appearance related reasons as well. PESs include both legal over the counter dietary supplements and illicit pharmacologic agents. This report reviews the current epidemiology of PES use in the pediatric population, as well as information on those PESs in most common use. Concerns regarding use of legal PESs include high rates of product contamination, correlation with future use of anabolic androgenic steroids, and adverse effects on the focus and experience of youth sports participation. The physical maturation and endogenous hormone production that occur in adolescence are associated with large improvements in strength and athletic performance. For most young athletes, PES use does not produce significant gains over those seen with the onset of puberty and adherence to an appropriate nutrition and training program.
Human wings apart like gene is specifically overexpressed in cervical cancer.
Venue: Oncology letters

Cervical cancer is the third most commonly diagnosed cancer in women. The human wings apart like (hWAPL) gene, which is 30,793 bp long and located on 10q23.2. is a human homologue of the WAPL gene in Drosophila melanogaster. hWAPL has the characteristics of an oncogene in uterine cervical cancer. The present study investigated the expression of the hWAPL gene in tissues, including 9 common cancers, consisting of cervical, gastric and lung cancers, liver, bladder, esophageal, endometrial, renal and rectal carcinomas, cervical intraepithelial neoplasia (CIN) and benign squamous epithelia. The immunohistochemical analysis was conducted using paraffin embedded tissues obtained from 413 patients, consisting of 27 benign squamous epithelial tissue samples, and 47 cervical cancer, 30 cervical intraepithelial neoplasia (CIN)I, 33 CINII, 38 CINIII, 29 gastric cancer, 28 liver carcinoma, 26 bladder carcinoma, 35 esophageal carcinoma, 25 endometrial, 26 renal carcinoma, 36 rectal carcinoma and 33 lung cancer tissues. The expression of hWAPL mRNA was evaluated by reverse transcription quantitative polymerase chain reaction in 8 benign squamous epithelia and 11 cervical cancer tissues. Compared to benign squamous epithelia and the 8 other cancers, hWAPL protein was significantly increased in cervical cancer (P<0.001) The expression of the hWAPL protein in cervical cancer and CINIII tissues was markedly increased compared to the expression in CINI and CINII tissues (P<0.001) Despite the significant difference in the staining scores (P<0.001) no significant difference was observed in the percentage of tissues expressing hWAPL (P=0.102) between cervical cancer and CINIII. The hWAPL gene may therefore be specifically overexpressed in cervical cancer. The overexpression of hWAPL may play an important role in occurrence and development of cervical cancer.
Gamification and Adherence to Web Based Mental Health Interventions: A Systematic Review
Venue: JMIR mental health

Adherence to effective Web based interventions for common mental disorders (CMDs) and well being remains a critical issue, with clear potential to increase effectiveness. Continued identification and examination of "active" technological components within Web based interventions has been called for. Gamification is the use of game design elements and features in nongame contexts. Health and lifestyle interventions have implemented a variety of game features in their design in an effort to encourage engagement and increase program adherence. The potential influence of gamification on program adherence has not been examined in the context of Web based interventions designed to manage CMDs and well being.  This study seeks to review the literature to examine whether gaming features predict or influence reported rates of program adherence in Web based interventions designed to manage CMDs and well being.  A systematic review was conducted of peer reviewed randomized controlled trials (RCTs) designed to manage CMDs or well being and incorporated gamification features. Seven electronic databases were searched.  A total of 61 RCTs met the inclusion criteria and 47 different intervention programs were identified. The majority were designed to manage depression using cognitive behavioral therapy. Eight of 10 popular gamification features reviewed were in use. The majority of studies utilized only one gamification feature (n=58) with a maximum of three features. The most commonly used feature was story/theme. Levels and game leaders were not used in this context. No studies explicitly examined the role of gamification features on program adherence. Usage data were not commonly reported. Interventions intended to be 10 weeks in duration had higher mean adherence than those intended to be 6 or 8 weeks in duration.  Gamification features have been incorporated into the design of interventions designed to treat CMD and well being. Further research is needed to improve understanding of gamification features on adherence and engagement in order to inform the design of future Web based health interventions in which adherence to treatment is of concern. Conclusions were limited by varied reporting of adherence and usage data.
Impact of a Dutch urban regeneration programme on mental health trends: a quasi experimental study
Venue: Journal of Epidemiology Community Health

This paper aims to assess the mental health impact of an urban regeneration programme implemented from 2008 onwards in the 40 most deprived districts in the Netherlands. Interventions varied from improvements in the built environment to activities promoting social cohesion.  We accessed repeated cross sectional data from the annual Health Interview Survey, for the period 2004 2011 among adults (n target districts=1445, n rest of the Netherlands=44 795) We used multilevel logistic regression models to compare the development of mental health in the target districts with the rest of the Netherlands and with comparably deprived districts. Results were presented as 'slope estimates' with corresponding 95% CIs. Finally, we analysed the trends by gender and by the intensity of the programme.  The trend change in mental health between the intervention and preintervention period was approximately the same in the target districts as in broadly comparably deprived control districts (D slope 0.06 0.08 to 0.20) However, among women, a tendency was found towards more positive trend changes in the target districts compared with control districts (D slope 0.17 0.01 to 0.34) Those districts that implemented an intensive programme experienced an improvement in mental health, while residents of the comparably deprived control districts experienced a deterioration, resulting in a statistically significantly more positive trend change between the preintervention and intervention period in those target districts (D slope 0.19 (0.01 to 0.38)  Implementing an urban regeneration programme with a wide range of intensive interventions may be effective in promoting good mental health. Further research is required to examine which mix of interventions is needed for the programme to be effective.
Development of a comprehensive model for stakeholder management in mental healthcare.
Venue: Journal of health organization and management

Stakeholder management is not yet incorporated into the standard practice of most healthcare providers. The purpose of this paper is to assess the applicability of a comprehensive model for stakeholder management in mental healthcare organization for more evidence based (stakeholder) management.  The assessment was performed in two research parts: the steps described in the model were executed in a single case study at a mental healthcare organization in the Netherlands; and a process and effect evaluation was done to find the supporting and impeding factors with regard to the applicability of the model. Interviews were held with managers and directors to evaluate the effectiveness of the model with a view to stakeholder management.  The stakeholder analysis resulted in the identification of eight stakeholder groups. Different expectations were identified for each of these groups. The analysis on performance gaps revealed that stakeholders generally find the collaboration with a mental healthcare provider "sufficient." Finally a prioritization showed that five stakeholder groups were seen as "definite" stakeholders by the organization.  The assessment of the model showed that it generated useful knowledge for more evidence based (stakeholder) management. Adaptation of the model is needed to increase its feasibility in practice.  Provided that the model is properly adapted for the specific field, the analysis can provide more knowledge on stakeholders and can help integrate stakeholder management as a comprehensive process in policy planning.
Internet Argument Corpus 2.0: An SQL schema for Dialogic Social Media and the Corpora to go with it
Venue: LREC

Large scale corpora have benefited many areas of research in natural language processing, but until recently, resources for dialogue have lagged behind. Now, with the emergence of large scale social media websites incorporating a threaded dialogue structure, content feedback, and self annotation (such as stance labeling) there are valuable new corpora available to researchers. In previous work, we released the INTERNET ARGUMENT CORPUS, one of the first larger scale resources available for opinion sharing dialogue. We now release the INTERNET ARGUMENT CORPUS 2.0 (IAC 2.0) in the hope that others will find it as useful as we have. The IAC 2.0 provides more data than IAC 1.0 and organizes it using an extensible, repurposable SQL schema. The database structure in conjunction with the associated code facilitates querying from and combining multiple dialogically structured data sources. The IAC 2.0 schema provides support for forum posts, quotations, markup (bold, italic, etc) and various annotations, including Stanford CoreNLP annotations. We demonstrate the generalizablity of the schema by providing code to import the ConVote corpus.
Argument Mining: the Bottleneck of Knowledge and Language Resources
Venue: LREC

Given a controversial issue, argument mining from natural language texts (news papers, and any form of text on the Internet) is extremely challenging: domain knowledge is often required together with appropriate forms of inferences to identify arguments. This contribution explores the types of knowledge that are required and how they can be paired with reasoning schemes, language processing and language resources to accurately mine arguments. We show via corpus analysis that the Generative Lexicon, enhanced in different manners and viewed as both a lexicon and a domain knowledge representation, is a relevant approach. In this paper, corpus annotation for argument mining is first developed, then we show how the generative lexicon approach must be adapted and how it can be paired with language processing patterns to extract and specify the nature of arguments. Our approach to argument mining is thus \bf knowledge driven
Effects of learning analytics dashboard: analyzing the relations among dashboard utilization, satisfaction, and learning achievement

The learning analytics dashboard (LAD) is a newly developed learning support tool for virtual classrooms that is believed to allow students to review their online learning behavior patterns intuitively through the provision of visual information. The purpose of this study was to empirically validate the effects of LAD. An experimental study was conducted with a dashboard treatment group and a control group. The researchers developed a LAD and evaluated its effectiveness on the sample of 151 college students at a private university located in Korea, who were taking the online course titled "Management Statistics" in the first semester of 2014. The following results were obtained. First, the students who received dashboard treatment presented higher final score than those who did not. Second, the dashboard usage frequency, as measured by the number of times the dashboard was opened, did not have a significant impact on learning achievement. However, a slightly positive correlation between satisfaction with LAD and learning achievement was observed. Further analysis indicated that learners who used the dashboard only a few times showed relatively high satisfaction with LAD. On the other hand, high academic achievers who opened LAD relatively frequently showed lower satisfaction with dashboard. The results guide that LAD should be revised in a way to motivate learners consistently and support learners who have different academic achievement levels. The study discusses the further research tasks in terms of LAD development as an effective and personalized feedback tool to improve learners' academic achievement.
Aprender literatura infantil

La literatura adquiere un papel muy importante en la Educacion Infantil, son numerosas las veces en que estan presentes cuentos, poesias u obras de teatro en el proceso de ensenanza aprendizaje. Consideramos por ello importante, analizar la vision y conocimientos previos de los futuros maestros y maestras, asi como el tratamiento de la literatura con respecto a la formacion que reciben. Nos planteamos si es considerada como un medio para transmitir una ensenanza, valores morales, o el aprendizaje de la lectura y la escritura como unica funcion o si en estas edades tempranas deberiamos centrarnos mas en el disfrute y gusto por la lectura aunque con ello se consiga el enriquecimiento cultural y otros multiples aprendizajes. El instrumento utilizado para este estudio ha sido un cuestionario cuya muestra esta formada por el alumnado de 2o y 4.o curso de la titulacion del Grado maestro de Educacion Infantil. Nuestro objetivo es hacer ver a los estudiantes la necesidad e importancia de la Literatura Infantil en el aula asi como analizar su formacion y valorar si es suficiente para comprenderla y transmitirla de forma adecuada.
Do no harm versus do good social responsibility: Attributional thinking and the liability of foreignness

The efforts of multinational corporations to be socially responsible do not always engender positive evaluations from overseas stakeholders. Drawing on attribution theory, we argue that two heuristics guide stakeholders in evaluating firms' social performance: foreignness and the valence of firms' social responsibility. We provide evidence from a field study of secondary stakeholders and an experimental study involving 129 non governmental organizations. Consistent with attribution theory, the liability of foreignness is minimized when firms engage in "do good" social responsibility (focused on proactive engagement creating positive externalities) but is substantial when firms engage in "do no harm" social responsibility (focused on attenuating negative externalities) In online supporting information, Appendix S1, we demonstrate that these evaluations have consequences for whether stakeholders subsequently cooperate, or sow conflict, with firms.  There is no guarantee that efforts to be socially responsible will improve multinational corporations' relations with overseas stakeholders, such as customers, governments, and activists. In a field study and an experiment, we unpack when foreign firms suffer from harsh stakeholder evaluations. Foreign firms especially suffer from harsh evaluations when they conduct "do no harm" CSR rather than "do good" CSR. Stakeholders attribute the motive for foreign firms' do no harm CSR to managerial interests and shareholder pressures, perceiving a wedge between managers and owners (who may be unmotivated to reduce the negative impacts of their business activities) and local stakeholders (who bear the social costs) A practical implication is that foreign firms gain more from highlighting do good rather than do (no) harm CSR initiatives.
State of the Art in Techniques of Text Digital Watermarking: Challenges and Limitations
Venue: J. Comput. Sci.

Data protection from malicious attacks and misuse has become a crucial issue. Various types of data, including images, videos, audio and text documents, have given cause for the development of different methods for their protection. Cryptography, digital signatures and steganography are the most well known technologies used to protect data. During the last decade, digital watermarking technology has also been utilized as an alternative to prevent media forgery and tampering or falsification to ensure both copyright and authentication. Much work has been done to protect images, videos and audio but only a few algorithms have been considered for text document protection with digital watermarking. However, our survey observed that available text watermarking algorithms are neither robust nor imperceptible and as such remain unsecured methods of protection. Hence, research to improve the performance of text watermarking algorithms is required. This paper reviews current watermarking algorithms for text documents and categorizes text watermarking methods based on the way the text was treated during the watermarking process. It also discusses merits and demerits of available methods as well as recent proposed methods for evaluating text watermarking systems and the need for further research on digital text watermarking.
Baseline C Reactive Protein Level Predicts Survival of Early Stage Lung Cancer: Evidence from a Systematic Review and Meta Analysis
Venue: Tumori

The prognostic impact of baseline C reactive protein (CRP) in non small cell lung cancer (NSCLC) is debated. To evaluate this issue, we performed a systematic review and meta analysis to explore the role of CRP value in predicting early stage NSCLC survival.  Ten articles on early stage NSCLC were eligible and included in our study. We performed a random effects meta analysis and assessed heterogeneity and publication bias. We pooled hazard ratio (HR) estimates and their 95% confidence intervals (CIs) on mortality for the comparison between the study specific highest category of CRP level versus the lowest one.  In overall analysis, elevated pretreatment CRP values were significantly associated with poor overall survival (HR 1.60, 95% CI 1.30 1.97, p<0.001, I2 71.9% Similar results were observed across considered strata. However, higher mortality risk was reported in studies in which CRP was combined with other factors (HR 1.96, 95% CI 1.58 2.45) and in those using a cutoff value of 3 mg/L (HR 1.89, 95% CI 1.52 2.35)  Based on our analysis, baseline high CRP level is significantly associated with poor prognosis in early stage NSCLC. Further prospective controlled studies are needed to confirm these data.
