Authors: Ambrož Martin , Matoušková Petra , Skarka Adam , Zajdlová Martina , Žáková Kateřina , Skálová Lenka
Published: June 2017

β-caryophyllene oxide (CAO), α-humulene (HUM), trans-nerolidol (NER) and valencene (VAL) are constituents of the essential oil of Myrica rubra (MEO), which has significant antiproliferative effect in various cancer cell lines. In the present study, we compared the antiproliferative effect of these sesquiterpenes alone and in combination with the cytostatic drug doxorubicin (DOX) in cancer cell lines with different sensitivity to DOX. Two ovarian cancer cell lines (sensitive A2780 and partly resistant SKOV3) and two lymphoblast cancer cell lines (sensitive CCRF/CEM and completely resistant CEM/ADR) were used. The observed effects varied among sesquiterpenes and also differed in individual cell lines, with only VAL being effective in all the cell lines. A strong synergism of DOX with NER was found in the A2780 cells, while DOX acted synergistically with HUM and CAO in the SKOV3 cells. In the CCRF/CEM cells, a synergism of DOX with CAO and NER was observed. In resistant CEM/ADR cells, sesquiterpenes did not increase DOX efficacy, although they significantly increased accumulation of DOX (up to 10-times) and rhodamine-123 (substrate of efflux transporter ABCB1) within cancer cells. In conclusion, the tested sesquiterpenes were able to improve DOX efficacy in the sensitive and partly resistant cancer cells, but not in cells completely resistant to DOX.

Published: June 2017

In this study, the chitosan-induced coacervation of soy protein-isoflavone complexes in soymilk was investigated. Most of the soymilk proteins, including β-conglycinin (7S), glycinin (11S), and isoflavones, were found to coacervate into the soymilk pellet fraction (SPF) following the addition of 0.5% chitosan. The total protein in the soymilk supernatant fraction (SSF) decreased from 18.1 ± 0.3 mg/mL to 1.6 ± 0.1 mg/mL, and the pH values decreased slightly, from 6.6 ± 0.0 to 6.0 ± 0.0. The results of SDS-PAGE revealed that the 7S α’, 7S α, 7S β, 11S A3, and 11S acidic subunits, as well as the 11S basic proteins in the SSF, decreased to 0.7 ± 0.5%, 0.2 ± 0.1%, 0.1 ± 0.0%, 0.2 ± 0.2%, 0.2 ± 0.2% and 0.3 ± 0.2%, respectively. We also found that isoflavones in the SSF, including daidzein, glycitein, and genistein, decreased to 9.6 ± 2.3%, 5.7 ± 0.9% and 5.9 ± 1.5%, respectively. HPLC analysis indicated that isoflavones mixed with soy proteins formed soy protein-isoflavone complexes and were precipitated into the SPF by 0.5% chitosan.
Preparation of Ce- and La-Doped Li4Ti5O12 Nanosheets and Their Electrochemical Performance in Li Half Cell and Li4Ti5O12/LiFePO4 Full Cell Batteries
Authors: Qin Meng , Li Yueming , Lv Xiao-Jun
Published: June 2017

This work reports on the synthesis of rare earth-doped Li4Ti5O12 nanosheets with high electrochemical performance as anode material both in Li half and Li4Ti5O12/LiFePO4 full cell batteries. Through the combination of decreasing the particle size and doping by rare earth atoms (Ce and La), Ce and La doped Li4Ti5O12 nanosheets show the excellent electrochemical performance in terms of high specific capacity, good cycling stability and excellent rate performance in half cells. Notably, the Ce-doped Li4Ti5O12 shows good electrochemical performance as anode in a full cell which LiFePO4 was used as cathode. The superior electrochemical performance can be attributed to doping as well as the nanosized particle, which facilitates transportation of the lithium ion and electron transportation. This research shows that the rare earth doped Li4Ti5O12 nanosheets can be suitable as a high rate performance anode material in lithium-ion batteries.
Isothermal and Non-Isothermal Crystallization Studies of Long Chain Branched Polypropylene Containing Poly(ethylene-co-octene) under Quiescent and Shear Conditions
Authors: Zhang Zinan , Yu Fengyuan , Zhang Hongbin
Published: June 2017

Isothermal and non-isothermal crystallization behaviours of the blends of long chain branched polypropylene (LCB PP) and poly(ethylene-co-octene) (PEOc) with different weight ratios were studied under quiescent and shear flow using polarized optical microscopy (POM), differential scanning calorimetry (DSC), and rheological measurements. Experimental results showed that the crystallization of the LCB PP/PEOc blends were significantly accelerated due to the existence of the long chain branches (LCBs), the blends being able to rapidly crystallize even at 146 °C. The addition of PEOc that acts as a nucleating agent, could also increase the crystallization rate of LCB PP. However, the crystallization rate of LCB PP was reduced when the PEOc concentration was more than 60 wt %, showing a retarded crystallization growth mechanism. The morphology of the binary blend was changed from a sea-island structure to a co-continuous phase structure when the PEOc concentration was increased from 40 to 60 wt %. In comparison with linear isotactic iPP/PEOc, the interfacial tension between LCB PP and PEOc was increased. In addition, flow-induced crystallization of LCB PP/PEOc blends was observed. Possible crystallization mechanisms for both LCB PP/PEOc and iPP/PEOc blends were proposed.
Micro-Viscometer for Measuring Shear-Varying Blood Viscosity over a Wide-Ranging Shear Rate
Authors: Kim Byung , Lee Seung , Jee Solkeun , Atajanov Arslan , Yang Sung
Published: June 2017

In this study, a micro-viscometer is developed for measuring shear-varying blood viscosity over a wide-ranging shear rate. The micro-viscometer consists of 10 microfluidic channel arrays, each of which has a different micro-channel width. The proposed design enables the retrieval of 10 different shear rates from a single flow rate, thereby enabling the measurement of shear-varying blood viscosity with a fixed flow rate condition. For this purpose, an optimal design that guarantees accurate viscosity measurement is selected from a parametric study. The functionality of the micro-viscometer is verified by both numerical and experimental studies. The proposed micro-viscometer shows 6.8% (numerical) and 5.3% (experimental) in relative error when compared to the result from a standard rotational viscometer. Moreover, a reliability test is performed by repeated measurement (N = 7), and the result shows 2.69 ± 2.19% for the mean relative error. Accurate viscosity measurements are performed on blood samples with variations in the hematocrit (35%, 45%, and 55%), which significantly influences blood viscosity. Since the blood viscosity correlated with various physical parameters of the blood, the micro-viscometer is anticipated to be a significant advancement for realization of blood on a chip.
The Effect of Teaching Games of Understanding as a Coaching Instruction had on Adjust, Cover and Heart Rate among Malaysian and Indian Junior Hockey Players
Authors: Nathan Sanmuga
Published: June 2017

The field hockey coaching process across both Malaysia and India favours a traditional, coach-centred approach of mastering technical skills in terms of game play parameters, fitness, intensity, and load training, whereas a tactical- and player-centred pedagogical approach still takes a backseat. On the other hand, the Teaching Games for Understanding (TGfU) model offers tactical-cognitive instruction and is gaining international recognition for its ability to produce intelligent players via a problem-solving approach in game play. Therefore, the purpose of this quasi-experimental study was to investigate the effect of TGfU compared to skill mastery instruction, termed as Skill Drill Technical (SDT), among Malaysian and Indian elite junior hockey players in term of the game play attributes of adjust and cover in 5 vs. 5 small-sided game play and game play intensity via heart rate (HR) at different points of game play. A total of n = 60 players with an average age of 15 ± 1.03 was selected via simple random sampling from both countries involved in this study and assigned equally to groups, with 15 per group for TGfU and for SDT across Malaysia and India. Gathered data were analysed using the ANOVA and ANCOVA techniques. Findings indicated that there were no significant differences for adjust in 5 vs. 5 game play between TGfU and SDT across Malaysia and India after the intervention. For cover, there was significant improvement for Malaysian players using the TGfU model compared to SDT. In contrast, there was no significant difference between these two models among the Indian players after the intervention. There was significant difference between these two models in terms of warm-up HR across the two countries, and HR was higher via TGfU. For HR immediately after the 5 vs. 5 game play intervention and HR after three minutes’ recovery, Indian players with TGfU recorded a higher and significant difference compared to SDT. However, findings indicated no significant difference between these two instruction types among Malaysians, although TGfU proved to have higher HR intensity. Therefore, these findings reiterated that TGfU is a useful approach for game play to enhance intensity and cardiac output. In conclusion, for TGfU to be more relevant to the coaching environment, future research should link game play and physiological parameters. TGfU should able to overcome the barriers of tradition and cultural background that may hinder its momentum.
Using an AHP-ISM Based Method to Study the Vulnerability Factors of Urban Rail Transit System
Authors: Song Liangliang , Li Qiming , List George , Deng Yongliang , Lu Ping
Published: June 2017

As a sustainable means of public transportation, urban rail transit system undergoes rapid expansion in China. How to provide a safe and reliable service has been the subject of growing attention in this context. However, such work is challenging because rail transit systems are quite vulnerable and influenced by a set of interacting factors. Studying these vulnerability factors will contribute significantly to the operation of rail transit system. From this perspective, this paper made an exploration of the vulnerability factors based on an integrated method consisting of AHP (Analytical Hierarchy Process) and ISM (Interpretative Structural Modeling). Based on literature review, 21 vulnerability factors were identified. Subsequently, expert elicitation was employed to ascertain the importance of each factor and the interrelations among them. The results suggest that management and individual factors have the highest importance weights and the interrelations among vulnerability factors could be expressed as a five-layer structure, in which management factors were inclined to be at the lower level. The research provides valuable information for decision makers to take proactive strategies and reinforcement policies to guarantee safety operation of urban rail transit system and ensure urban public safety, which could promote the sustainable development of cities.
Clinical Manifestations and Outcomes of Rickettsia australis Infection: A 15-Year Retrospective Study of Hospitalized Patients
Authors: Stewart Adam , Armstrong Mark , Graves Stephen , Hajkowicz Krispin
Published: June 2017

Queensland tick typhus (QTT; Rickettsia australis) is an important cause of community-acquired acute febrile illness in eastern Australia. Cases of QTT were identified retrospectively from 2000 to 2015 at five sites in Northern Brisbane through a pathology database. Those included had a fourfold rise in spotted fever group (SFG)-specific serology, a single SFG-specific serology ≥ 256 or SFG-specific serology ≥ 128 with a clinically consistent illness. Cases were excluded on the basis of clinical unlikelihood of QTT infection. Thirty-six cases were included. Fever was found in 34/36 (94%) patients. Rash occurred in 83% of patients with maculopapular being the dominant morphology (70%). Thrombocytopenia, lymphopenia, and raised transaminases were common and occurred in 58%, 69%, and 89% of patients, respectively. Thirty-one of 36 (86%) patients received antibiotic therapy (usually doxycycline) and the time to correct antibiotic (from admission) ranged from 3 to 120 h (mean 45.5 h). Four of 36 (11%) required intensive care unit (ICU) admission for severe sepsis and end-organ support. There were no deaths. QTT has a wide range of clinical and laboratory features. Early and appropriate antimicrobial therapy is important and may prevent severe disease. Further prospective studies are required to identify factors associated with severe infection and sepsis.

Published: June 2017

The Orion OB1a sub-association is a rich low-mass star (LMS) region. Previous spectroscopic studies have confirmed 160 LMSs in the 25 Orionis stellar group (25 Ori), which is the most prominent overdensity of Orion OB1a. Nonetheless, the current census of the 25 Ori members is estimated to be lower than 50% complete, leaving a large number of members to be still confirmed. We retrieved 172 low-resolution stellar spectra in Orion OB1a observed as ancillary science in the SDSS-III/BOSS survey, for which we classified their spectral types and determined physical parameters. To determine memberships, we analyzed the

emission, Li i
λ6708 absorption, and Na i
λλ8183, 8195 absorption as youth indicators in stars classified as M type. We report 50 new LMSs spread across the 25 Orionis, ASCC 18, and ASCC 20 stellar groups with spectral types from M0 to M6, corresponding to a mass range of

. This represents an increase of 50% in the number of known LMSs in the area and a net increase of 20% in the number of 25 Ori members in this mass range. Using parallax values from the Gaia DR1 catalog, we estimated the distances to these three stellar groups and found that they are all co-distant, at 338 ± 66 pc. We analyzed the spectral energy distributions of these LMSs and classified their disks into evolutionary classes. Using H-R diagrams, we found a suggestion that 25 Ori could be slightly older than the other two observed groups in Orion OB1a.

Après avoir distingué les « droites extrêmes » des « extrêmes droites », l’article analyse la fascisation des espaces publics et fait le point sur les diverses manifestations de ces tendances en ligne au cours de la dernière décennie, évoquant les modes de mobilisation du réseau Internet par différents mouvements (Tea Party, Manif pour tous, Pegida, etc.). Dans un second temps sont dégagés les principaux traits des « droites extrêmes » à travers les tendances à la fabrication de l’« autre », la personnalisation des malaises sociaux, la « dépluralisation » du monde, le « déni de réalité » et l’« adresse autoritaire ».
Portrait de l’agitateur américain
Authors: Löwenthal Leo , Guterman Norbert , Gimenez Elsa , Voirol Olivier
Published: June 2017

À partir d’une étude des techniques développées par les activistes d’extrême droite aux États-Unis au milieu des années 1940, les auteurs s’attachent à saisir en détail les ressorts rhétoriques employés par ces agitateurs pour constituer leurs audiences. Ce faisant, ils dégagent les traits d’une expression politique attachée aux logiques fascistes : l’agitation. Se nourrissant du malaise social dont elle fait son fonds de commerce, l’agitation mobilise un catalogue de griefs incitant ses destinataires à des émotions destructrices : la méfiance, la dépendance, l’exclusion, l’anxiété et le désillusionnement. À la différence du militantisme réformiste ou révolutionnaire, elle ne vise pas un réel changement social mais incite ses destinataires à diriger leurs colères contre des cibles personnifiées tout en se complaisant dans un statu quo social, économique et politique.
Une communication par les marges du parti ?

Published: June 2017

Quels rapports les groupes Facebook proches du Front national entretiennent-ils avec le parti en tant qu’organisation ? Cet article propose de nuancer l’image d’une expression du parti qui serait clivée entre, d’un côté, des groupes de militants à la parole incontrôlable et, de l’autre, les élus et officiels du parti, à la parole lissée. Par une étude de 158 de ces groupes et de certains de leurs promoteurs, l’article montre qu’il existe une relative continuité entre la base militante, dont émerge un ensemble de petits entrepreneurs politiques que le parti ne veut pas intégrer, et des élus de niveau secondaire.
Observer Les Observateurs

Published: June 2017

Parmi les mutations en cours sur l’échiquier politique européen, l’un des phénomènes les plus marquants concerne l’essor de sites web populistes qui, prétextant une invisibilisation médiatique des opinions de la droite radicale, s’engagent dans une démarche de « réinformation » des citoyens considérés comme désinformés par des médias frappés de « bien-pensance gauchisante ». Cet article décrit l’origine et le développement de l’un de ces sites, www.lesobservateurs.ch , fondé en février 2012 en Suisse par un professeur de sociologie à la retraite. Par l’étude de ses connexions et collaborations avec les sites français de la même obédience, il met au jour un phénomène de circulation circulaire de l’information, qui contribue à l’émergence d’une réinfosphère transnationale par l’extension de l’audience des thèses populistes sur la Toile. Ce faisant, l’analyse proposée questionne empiriquement des mutations à la fois idéologiques et techniques de la communication politique, dont Internet est devenu le médium privilégié.
Attendre le signal
Authors: Camus Laurent
Published: June 2017

L’article questionne le caractère interruptif des « cérémonies télévisées » de Dayan et Katz (1996), l’idée selon laquelle les événements retransmis en direct à la télévision interrompent le cours des activités ordinaires des téléspectateurs et reconfigurent les grilles de programmation télévisuelles. Plutôt que de voir dans l’interruption une propriété intrinsèque des événements en direct, l’article examine les pratiques de prise d’antenne, par lesquelles les participants d’une régie télévisée synchronisent le temps de l’événement avec la temporalité de sa retransmission. Il montre ainsi comment ils soumettent l’événement à l’agenda télévisuel et lient ses acteurs à l’attente conjointe de l’arrivée du signal. La démarche méthodologique de cet article, inspirée de l’ethnométhodologie et de l’analyse conversationnelle, consiste à ramener les programmes télévisés à la dimension vécue et contextuelle des interactions en coprésence qui les constituent. Il s’appuie sur une analyse vidéo des interactions d’une régie lors de la réalisation télévisée de matches de football retransmis en direct.
Diffusion et déformations d’un slogan publicitaire mémorable dans la presse écrite : le cas de « Nespresso. What else ? »
Authors: Desnica Mirta
Published: June 2017

À partir de 2006, Nespresso lance une série de publicités télévisées afin de s’imposer comme l’icône de l’excellence du café en capsules. Le slogan « Nespresso . What else ?  » synthétise la désirabilité extrême du café Nespresso, qui rend son choix évident. La grande notoriété de la « série » publicitaire a permis au slogan de pénétrer dans le discours journalistique. En s’inspirant de la notion de mème de Dawkins, et en appliquant sa conception de ces « réplicateurs culturels » à un objet langagier, la présente contribution étudie les raisons linguistiques du succès du slogan – son caractère « mémorable » –, et ses échos dans la presse d’information générale française, afin d’apprécier les similarités et les différences par rapport à la forme, le sens et le contexte de l’énoncé initial. L’analyse qualitative s’appuie sur un corpus de textes extraits de huit quotidiens et deux hebdomadaires à l’aide de la base de données Factiva, parus avant novembre 2015.
Le tweet politique efficace comme mème textuel : du profilage à viralité
Authors: Longhi Julien
Published: June 2017

Dans le cadre d’une recherche sur l’analyse des tweets politiques, cet article s’intéresse à la propension de ces formes à circuler, en se focalisant sur leur efficacité, définie en fonction du nombre de fois où un tweet est « retweeté » ou « favorisé ». Cette efficacité, au regard de la circulation des messages sur internet, permet de saisir leur viralité : nous faisons ainsi l’hypothèse de l’existence, pour le tweet politique, d’une forme de mème plus textuelle que langagière, puisque c’est, tout autant que l’emploi de certains termes, leur mise en syntagme particulière et selon certains points de vue (le profilage) qui en fait le succès et la viralité. C’est donc à l’échelle du tweet dans son ensemble que se résoudrait la question de sa viralité, par la prise en compte de la circulation et de son efficacité.
Justesse d’expression et questions de synonymie dans le Dictionnaire néologique (1726) de l’Abbé Desfontaines
Authors: Schweitzer Claudia
Published: June 2017

À l’époque où l’Abbé Desfontaines publie son Dictionnaire néologique , on réfléchit surtout à la justesse des mots dans l’objectif de garantir un style correspondant au bon usage. Il ne s’agit pas de juger le langage en termes de créativité, de dégradation, d’effets de mode langagiers ou de ‘particularité’ de la langue, comme à l’heure actuelle. En revanche, le débat s’inscrit notamment dans la volonté de régler l’usage et d’établir des normes fixes pour le français, la langue nationale commune. On rejoint ici, certes, les travaux des premiers dictionnaires et des Remarqueurs, mais aussi ceux portant sur la synonymie, comme La justesse de la langue françoise de Gabriel Girard (1718). Cet article situe l’œuvre et les méthodes utilisées par Desfontaines dans ce contexte.

Published: June 2017

Patella fracture fixation remains a significant challenge for orthopedic surgeons. Although tension band fixation allows for reliable osseous union, especially in simple fracture patterns, it still presents several problems. Plate fixation of patella fractures is a method that allows for more rigid stabilization and earlier mobilization. At the authors' level 1 trauma center, one fellowship-trained trauma surgeon has transitioned to using a novel anterior, low-profile mesh plate construct for all types of patella fractures. This construct allows for stable fixation, osseous union, and neutralization of the inferior pole for even the most comminuted of patella fractures. [

La formación de un nuevo paisaje en el centro de la península ibérica en el periodo posromano: el yacimiento de La Genestosa (Casillas de Flores, Salamanca)
Authors: Martín Viso Iñaki , Rubio Díez Rubén , López Sáez José Antonio , Ruiz Alonso Mónica , Pérez Díaz Sebastián
Published: June 2017

Este artículo presenta los datos de las intervenciones arqueológicas realizadas en La Genestosa (Casillas de Flores, Salamanca) en los años 2012 y 2013. Gracias al estudio de los materiales recuperados (cerámicas, vidrios, pizarras numerales), del estudio de las viviendas y de los análisis polínicos, se puede comprender la dinámica del paisaje rural en este sector del centro de la península ibérica. Se detecta la colonización de espacios de uso flexible con fines ganaderos, que serían la consecuencia de una iniciativa por grupos campesinos con diferencias internas, quienes crearon nuevos asentamientos. La coincidencia con el episodio frío altomedieval (450-950 d. C.) conllevó que determinados espacios húmedos se convirtiesen en áreas críticas, condicionando los patrones de asentamiento.
A cerâmica de tipo Kuass em Mértola (Portugal). As escavações da Biblioteca Municipal
Authors: Soría Vincenzo , Palma Maria de Fátima
Published: June 2017

En las últimas décadas, la cerámica de tipo Kuass se ha convertido en un indicador cronológico fiable de época prerromana y republicana en el sur peninsular (S. IV-V a. C.). Pero su valor no se limita sólo a este contexto: la cerámica utilizada para el consumo de alimentos es particularmente interesante para entender los gustos y opciones tomadas en el momento de la compra de estos productos por parte de las comunidades antiguas. El hecho de que se trate de un objeto exógeno, cuya tradición cerámica inspirada en el repertorio ático, no debe relegar a segundo plano el papel de sustrato local en términos de aceptación / rechazo de ciertas formas. El objetivo de este estudio fue dar a conocer un conjunto grande y sin precedentes de cerámica de tipo Kuass en un territorio particularmente estratégico para la distribución de productos en la Antigüedad, como es el área urbana de la antigua ciudad de Myrtilis, de modo a establecer bases sólidas para, posteriormente, elaborar un análisis comparativo macro regional.

Published: June 2017

A los pies del oppidum ibérico de Iliberri en la ciudad de Granada, una excavación de urgencia en la calle Zacatín ha permitido desvelar una fosa, en cuyo interior fueron exhumados entre diversos objetos, 5000 fragmentos de cerámica (mayoritariamente griega, aunque también ibérica), así como recipientes de vidrio de origen griego. No obstante, su contexto preciso y su función están todavía por determinar. El material cerámico griego está compuesto por vasos áticos (2000 fragmentos) y presenta un carácter formal et iconográfico muy homogéneo. Nos encontramos mayoritariamente frente a copas de pie bajo, escasas copas con pie alto (forma poco abundante en la península Ibérica a la excepción de Ampurias) y de escifoi. Este conjunto podría ser datado hacia el segundo cuarto del siglo IV a. C., siendo principalmente atribuible al pintor de Viena 116, así como ciertas piezas al Grupo FB o al pintor de Meleagro. De naturaleza excepcional, por su volumen y homogeneidad, este hallazgo permite y permitirá ahondar en las cuestiones de estructuración y de organización de los talleres de cerámica de Atenas, así como sobre las modalidades de su transporte.
Building Gene Networks by Analyzing Gene Expression Profiles
Authors: Gallo Crescenzio
Published: June 2017

The possible applications of modeling and simulation in the field of bioinformatics are very extensive, ranging from understanding basic metabolic paths to exploring genetic variability. Experimental results carried out with DNA microarrays allow researchers to measure expression levels for thousands of genes simultaneously, across different conditions and over time. A key step in the analysis of gene expression data is the detection of groups of genes that manifest similar expression patterns. In this chapter we examine various methods for analyzing gene expression data, addressing the important topics of (1) selecting the most differentially expressed genes, (2) grouping them by means of their relationships, and (3) classifying samples based on gene expressions.
Understanding Cloud Computing in a Higher Education Context
Authors: Self Lucy , Chamakiotis Petros
Published: June 2017

Cloud computing has become prevalent in many sectors today, including higher-education. The study is premised on the assumption that despite the popularity of cloud computing in higher education, research within this context remains limited. The study, which is qualitative and exploratory in nature, involved an innovative methodological approach, drawing on interviews with three groups of participants: (a) members of a global, Fortune 100 technology company supplying cloud solutions; (b) members of a selected UK university's IT department implementing cloud solutions; and (c) students from the same UK university using cloud solutions. The findings improve understanding around cloud solutions in the higher education context by unpacking—through a qualitative thematic analysis approach—relevant themes that inform the extant information systems literature. Finally, the study provides recommendations for future researchers, cloud suppliers, universities, and students.

Authors: Crawford Caroline M.
Published: June 2017

The impact of the instructional real world community engagement upon the learner's cognitive understanding and subject matter attainment is recognized as a viable and integrally important element within the learner's instructional process. The integration of an active instructional engagement at the real world community engagement level supports recognition of academic communities of engagement, personal communities of engagement, and professional communities of engagement. The academic community of engagement includes current course colleagues, prior course collegial support systems, and current and prior instructors. Within personal communities of engagement falls friends, family, and social connections. Within professional communities of engagement falls current work colleagues, prior work collegial support systems, and professional organization colleagues.
Relationship Among Intelligence, Achievement Motivation, Type of School, and Academic Performance of Kenyan Urban Primary School Pupils
Authors: Muthee Jessina Mukomunene , Murungi Catherine G.
Published: June 2017

This chapter determines the extent to which primary school academic performance was influenced by the criterion variables. Two hundred pupils male and female of age 12 and 14.5years from both public and private primary schools in Nairobi city participated in the study. Multiple regression and t-test were used for data analysis. The results revealed that three independent variables; intelligence, achievement, motivation and type of school jointly and significantly contributed to the prediction of academic achievement of the urban primary school pupils. (R = 0.693, P < .01). In terms of magnitude of contribution, intelligence turned out to be the most significant predictor (Beta = .445, t = 7.503, P< .01) followed by achievement motivation (beta = 0.282, t – 5.042, P< .01) and type of school (Beta = 0.208, t = 3.615, P < .01). The results of t – test revealed that students from private schools differ significantly from students of public schools in academic achievement and intelligence but not in terms of achievement motivation.
Analysis of Two Phases Queue With Vacations and Breakdowns Under T-Policy
Authors: Alnowibet Khalid , Tadj Lotfi
Published: June 2017

The service system considered in this chapter is characterized by an unreliable server. Random breakdowns occur on the server and the repair may not be immediate. We assume the possibility that the server may take a vacation at the end of a given service completion. The server resumes operation according to T-policy to check if enough customers have arrived while he was away. The actual service of any arrival takes place in two consecutive phases. Both service phases are independent of each other. A Markov chain approach is used to obtain the steady state system size probabilities and different performance measures. The optimal value of the threshold level is obtained analytically.
Exploratory Data Analysis on Breast Cancer Prognosis
Authors: O. Mohammad Mehdi Owrang , Kanaan Yasmine M. , Copeland Jr. Robert L. , Gaskins Melvin , DeWitty Jr. Robert L.
Published: June 2017

Breast cancer prognosis is a vital element of providing effective treatment for breast cancer patients. Breast cancer prediction survivability has mainly been studied based on pathological factors such as tumor size, tumor grade, number of positive lymph nodes, and hormone receptors among others. This chapter looks at the significance of the non-clinical prognostic factors of age, ethnicity, and marital status in finding the prognosis for breast cancer patients. The National Cancer Institute's SEER data and the Howard University Cancer Center Tumor Registry data are analyzed. Prognostic tool NPI (Nottingham Prognostic Index) and survival analysis tools of Cox proportional hazards and Kaplan-Meier survival curve are used in analyzing the experiments. The results suggest that age, ethnicity, and marital status have some influence on the survivability rate of breast cancer patients.

Published: June 2017

This chapter conducts the study on the use of text mining for corporate disclosure measurement. During the last few decades, research on corporate disclosure has received significant concentration from the researchers. Corporate disclosure measurement has been used by researchers to reveal the real world scenario of corporate disclosure practice. Very often, the researchers have used content analysis for making comments on the corporate disclosure practice. This chapter investigates the usability of text mining approaches for measuring the corporate disclosure. To do this, stages and general techniques of text mining have been discussed. The usability and advantages of text mining approaches for corporate disclosure measurement have been investigated. And prospective stages of text mining have been proposed to measure the corporate disclosure. The investigation and study indicates that text mining can contribute significantly to measure the corporate disclosure.
A Family Review of Parameter-Learning Models and Algorithms for Making Actionable Decisions
Authors: Ngan Chun-Kit
Published: June 2017

The authors describe and explain a family development of the parameter-learning models and algorithms: Expert Query Parametric Estimation (EQPE)-based models and Checkpoint-oriented algorithms. This class of models and algorithms combines the strength of both qualitative and quantitative methodologies to complement each other to learn optimal decision parameters in an efficient manner to make actionable recommendations. More specifically, this family of models and algorithms relies on domain expertise to select attributes and conditions against the data, from which the family of EQPE-based models and Checkpoint-oriented algorithms can learn decision parameters efficiently. To demonstrate the effectiveness and the efficiency of the models and algorithms, the authors have conducted the two experimental case studies, i.e., the stock market and the glycemia, respectively. The authors show that their approaches are more effective and produce the results that are superior to those of the two other approaches mentioned above.
Uberization (or Uberification) of the Economy
Authors: Daidj Nabyla
Published: June 2017

The global availability of the Internet, along with innovations (innovation comes in a variety of products, services and applications) explain certain aspects of the dynamics of the innovation process, the diffusion of technology and the development of various platforms (product and service marketplace, social networking platform, content platform). Uber has been a driving force behind the emergence of new kind of platforms services connecting consumers and providers in real time and organizing information without any ownership of the products concerned. Uber has changed the rules of the economic game and its success has inspired the term “uberization”. Uberization exposes both traditional groups to direct competition with new entrants (especially peer-to-peer platforms operators). This fast-growing phenomenon is seen today as an important feature of economic transformation.

Enhancing the Resiliency of Smart Grid Monitoring and Control
Authors: Zhao Wenbing
Published: June 2017

In this chapter, we present the justification and a feasibility study of applying the Byzantine fault tolerance (BFT) technology to electric power grid health monitoring. We propose a set of BFT mechanisms needed to handle the PMU data reporting and control commands issuing to the IEDs. We report an empirical study to assess the feasibility of using the BFT technology for reliable and secure electric power grid health monitoring and control. We show that under the LAN environment, the overhead and jitter introduced by the BFT mechanisms are negligible, and consequently, Byzantine fault tolerance could readily be used to improve the security and reliability of electric power grid monitoring and control while meeting the stringent real-time communication requirement for SCADA operations.
Model for Assessment of Environmental Responsibility in Health Care Organizations
Authors: Carnero María Carmen
Published: June 2017

Sustainability is considered a paradigm for businesses in the 21st Century. Despite this, the existing tools for helping to introduce strategies and manage activities to promote sustainable business are few. These deficiencies become more important in Health Care Organizations owing to its particular conditions of resource consumption and waste production. It is, therefore, essential to have objective tools to assist in monitoring environmental sustainability in this type of organization. This Chapter therefore sets out a multicriteria assessment system constructed by extension to a fuzzy environment of the Technique for Order Preference by Similarity to Ideal Situation (TOPSIS), to assess the environmental responsibility of a Health Care Organization. This model allows joint evaluation of a significant number of decision criteria. The aim is to provide a hospital with a model which is easy to apply, with criteria specific to health care, and which allows its responsibility with regard to the environment to be monitored over time. The model has been used in a Public Hospital.
Presidential Elections Web 2.0
Authors: McNeal Ramona Sue , Bryan Lisa Dotterweich
Published: June 2017

Has social media changed voter participation in presidential campaigns? Prior research has found that advances in social media has resulted in candidates focusing more on the “ground war” and less on mass media. Nevertheless candidates could be doing more to incorporate the Internet into their campaigns. This is particularly true when using social media in a manner that could allow interaction between the candidate and supporters. Candidates had been structuring social media use in a manner that gave an illusion of interaction. This has recently changed as a result of the success of Republican nominee Donald Trump during the 2016 presidential primaries. This success had been in part because of his strong social media presence which has led to other candidates changing their social media use. This chapter explores the change in social media use in presidential elections and its impact on voter turnout.
Peer-to-Peer Health-Related Online Support Groups
Authors: Coulson Neil S.
Published: June 2017

In recent years, the Internet has provided new opportunities for individuals living with health-related problems to communicate with each other via online support groups. These groups offer many unique advantages, such as convenience, anonymity, and access to a diverse range of group members. However, there are potential disadvantages to their use, for example, misleading information. Within such groups, patients may talk about a range of issues and provide support to one another, particularly informational and emotional support. Through self-disclosure and empathic communication, members may feel able to share personal stories as well as help others. Whilst robust evidence for their effectiveness is lacking, there is much qualitative and cross-sectional evidence suggesting that participation in online support groups may be beneficial. However, there is an urgent need for randomised controlled trials of pure peer-to-peer online support interventions across both physical and mental health conditions.
Software Evaluation From the Perspective of Patients and Healthcare Professionals
Authors: Rijo Rui Pedro Charters Lopes , Alves Domingos
Published: June 2017

Healthcare software evaluation is a complex process. Specifically, in the health information systems, focusing on the patients' health and on the healthcare professionals' motivation is particularly important. Doctors, nurses and other healthcare professionals use software that indirectly affects the patients. Does software improve the patients' health, their satisfaction, or the healthcare professionals' commitment/job satisfaction? How can the impact of an information system be measured from the perspective of the patients, the doctors, the nurses or the supporting staff? Some relevant efforts have been made in the last years to measure healthcare software impact. Nevertheless, the decision to extend a study to different fields may lead to many difficulties as far as its conclusions are concerned. By identifying the research questions and the most relevant works, as well as indicating the open research issue, this article is a revision of the literature on the subject. This work may be expected to be useful to all those wishing to contribute by their research in this field.
Experiences of Implementing a Large-Scale Blended, Flipped Learning Project
Authors: Owen Hazel , Dunham Nicola
Published: June 2017

In the context of ongoing global adoption of all forms of technology eLearning has continued to evolve, informed by a growing body of research. Many schools, tertiary institutions, and other organisations, are implementing a variety of eLearning initiatives, although, frequently it appears the investment does not always equate to more engaged, knowledgeable, skilled learners. Tertiary education in Aotearoa, New Zealand covers all post-secondary education and is analogous to the term Higher Education in other countries. This chapter draws on the implementation of a large-scale blended, flipped learning project at a tertiary institution in Aotearoa, New Zealand. The project (within the Health Science faculty) was driven by a desire to improve student learning experiences, and develop a common semester with a suite of interdisciplinary postgraduate qualifications. The discussion is based on personal reflections, which provide different perspectives of the initial phases, from three participants in the associated study (two of whom are also the authors of this chapter). During the project two key prevalences were observed. The first was an ingrained set of beliefs, often unquestioned, that shaped overall expectations of what an eLearning experience might comprise. Interpretations and implications are discussed using the lens of mindsets to illustrate how beliefs of ‘self' fundamentally influence a person's ability to embrace - and thrive in - a period of change. The second prevalence was a familiarity with large-scale, ‘monolithic' eLearning developments, which translated into discomfort with an agile approach. The overall aim of this chapter is to provide sufficient detail to draw educators and administrators together to apply the recommendations offered, while providing support for 'change agents' - as well as those ambivalent about reform. The authors are keen to highlight how ultimately rewarding, but also emotionally and physically demanding, the implementation of reform can be for those educators on 'the front lines'.

Published: June 2017

In this research the community of inquiry model is used as an analytical framework, along with quantitative content analysis and social network analysis, in order to understand how social and cognitive presence and group structure are affected by type of learning task and social networks. Discussion forums were employed focusing on three types of tasks: analyzing, evaluating, and creating. Over a period of three academic years, a total of 96 discussion forums were analyzed. Results show how social and cognitive presence, are affected by social group structure and centrality of coordinators, depending of type of learning task.
High-Performance Reconfigurable Computing
Authors: Vestias Mário Pereira
Published: June 2017

High-Performance Reconfigurable Computing systems integrate reconfigurable technology in the computing architecture to improve performance. Besides performance, reconfigurable hardware devices also achieve lower power consumption compared to General-Purpose Processors. Better performance and lower power consumption could be achieved using Application Specific Integrated Circuit (ASIC) technology. However, ASICs are not reconfigurable, turning them application specific. Reconfigurable logic becomes a major advantage when hardware flexibility permits to speed up whatever the application with the same hardware module. The first and most common devices utilized for reconfigurable computing are fine-grained FPGAs with a large hardware flexibility. To reduce the performance and area overhead associated with the reconfigurability, coarse-grained reconfigurable solutions has been proposed as a way to achieve better performance and lower power consumption. In this chapter we will provide a description of reconfigurable hardware for high performance computing.
