Objetivo: Identificar los factores asociados al intento de suicidio y la frecuencia en su presentación en niños y adolescentes estudiantes de dos instituciones educativas del municipio de Pácora-Caldas, Colombia. Método: Estudio tipo corte transversal. Para la medición de factores asociados, se utilizaron las escalas de dependencia alcohólica de Cage, Apgar familiar, acoso de Cisneros, autoestima de Rosenberg y la escala de ansiedad y depresión hospitalaria. Resultados: Participaron 180 estudiantes, con un promedio de  edad de 14,1±2,1 años, 53,3% género femenino, 27,2% de consumo de alcohol, acoso alto25%, y muy alto de 5,6%, 46,7% con buen funcionamiento familiar. La frecuencia de  intento de suicidio fue de 13,3%, los que habían efectuado intentos de suicidio, lo hicieron un promedio de 2,38±2,62 veces. Entre los factores asociados el más significativo fue la presencia de acoso entre pares (bullying) con una razón de prevalencia de 18,52, seguido de baja autoestima 15,376, abuso sexual 14,1, enfermedades mentales 14,1, presencia de ansiedad 8,94. Dependencia alcohólica 6,1, maltrato intrafamiliar 5,64, género femenino 3,23 y consumo de cigarrillo con 3,1. Conclusiones: Esta población presenta una alta frecuencia de intento suicida, posiblemente debida a la alta proporción de acoso entre pares detectada de 30% aproximadamente. Esto hace necesaria una pronta intervención.
Motivos de consulta y creación de contextos de ayuda: reflexiones y retos desde la experiencia clínica sistémica
Authors: Londoño Ruiz Marcela
Published: March 2018

Artículo de reflexión que integra las comprensiones epistemológicas acerca de la experiencia en práctica clínica desde una intervención sistémica, en el marco del proceso formativo en la Maestría en Psicología Clínica y de Familia, de la Universidad Santo Tomás. Las reflexiones se organizan a partir de la pregunta ¿Cuáles son los retos de un psicólogo clínico sistémico para la configuración de contextos de ayuda posibilitadores de la creación y del cambio? Para responder a la pregunta, se plantean 3 focos que implican retos paradigmáticos y pragmáticos como son: 1. La construcción de sistemas de ayuda y espacios psicoterapéuticos, 2. Las lecturas y guiones de intervención cuando las parejas, niños(as), adolescentes o adultos mayores son identificados como portadores del motivo de consulta y 3. Las posturas éticas y políticas en el ejercicio de la psicología clínica. Se parte de reconocer su permanente inter juego en los procesos de intervención sistémica.  Se concluye que los retos planteados pueden configurarse como principios para el desarrollo de procesos psicoterapéuticos desde una psicología clínica sistémica/compleja

O mercado de mangás e a cultura da convergência: descentralizando as decisões
Authors: De Freitas Ricardo Oliveira , Bittencourt Danilo Andrade
Published: March 2018

ResumoDesde a década de 2000, o mercado de mangás no Brasil conta com um relevante fandom consumidor que discute e organiza eventos. Contudo, com o advento da internet, as opiniões e ações destes fãs passaram a interferir, de forma cada vez mais incisiva, nas decisões de mercado de grandes editoras. Narrativas que antes dependiam de grandes emissoras e editoras para adentrar o mercado nacional, hoje são acessíveis graças à livre tradução e distribuição de fãs no espaço virtual. Este artigo resulta de uma breve investigação de viés exploratório e alicerçada no levantamento de dados bibliográficos sobre esta nova dimensão na distribuição de mangás. O evento para fãs Anime Friends e as atividades do blog MBB Anikenkai ilustram e confirmam a existência deste novo cenário. Abre-se um novo horizonte de investigações: o da análise da distribuição dos mangás e das suas diferentes faces midiáticas, levando em conta a interação entre fãs e editoras de mangá.Palavras-chaveMangás.

Published: March 2018

Gaillac red wine powder and Cinnamon cassia essential oil were selected for their in vitro antibacterial activity against Staphylococcus aureus CNRZ3 and Listeria innocua LRGIA 01, respectively. In order to assess the potential application of Gaillac wine powder to the preservation of raw meat, its antibacterial activity was assayed in Mueller Hinton broth supplemented with up to 20% (w/w) bovine meat proteins (bovine meat protein content): Gaillac wine powder as well as resveratrol, a stilbene polyphenol present in red wine, lost their antibacterial activity, likely as a result of interactions of Gaillac wine antibacterial molecules with bovine meat proteins at the expense of their interactions with S. aureus CNRZ3 cells. Cinnamon cassia essential oil antibacterial activity assays in Tryptone Soya broth, skimmed, semi-skimmed, and whole milk showed that its antibacterial activity was significantly reduced by milk fat globules but not by milk proteins: it could thus be used for the preservation of skimmed milk. The developed methodology based on the use of microbiological media mimicking the composition of perishable foods or of liquid foods such as sterilized milk with various milk fat contents could be used for the rapid screening of antibacterial plant extracts of interest for perishable foods preservation.
Modeling of Biosorption of Chromium by Immobilized Whole Cells of Aspergillus awamori NRRL 3112
Authors: Daniel David K , Vaishnavi Mahadavan
Published: March 2018

The presence of chromium in high concentrations in industrial effluents is of major concern, being extremely toxic and non-biodegradable, thus persistent and harmful to the ecosystem. Using microorganisms for adsorption of heavy metals has emerged as a potential alternative over the conventional methods and is gaining significance due to its incontestable merits. Since fungi amass metals more than their nutritional requirement, the present study in investigation of efficiency of Aspergillus awamori NRRL 3112 biomass for sorption of chromium by means of development of an immobilised whole cell system is significant. The effect of operational parameters like initial chromium concentration, time, temperature and pH on chromium removal was studied and the efficient conditions for the process were established. Kinetics studies revealed that, the pseudo second order model was found to best represent the process with higher R2 values than others. The Langmuir and Freundlich isotherms were applied and the Langmuir isotherm was found to be the best fit. It was also established by means of thermodynamic analysis that the biosorption occurred chemically and the process was more feasible, spontaneous and efficient at lower temperatures.

In this study, it was reported that the preparation and characterization of capacitive sensor based on conducting polymer for detection of dopamine and/or epinephrine by impedimetric method, electrochemical impedance spectroscopy. Pt electrodes coated with poly(Cz) and poly(In) in different electrolyte solution by electropolymerization. NaClO4-ACN electrolyte solution was selected as suitable electrolyte solution, due to high capacitive behavior. The usage of EIS technique for the determination of DA or EP in presence of AA was investigated. For this reason, the measurement EIS of prepared polymer coated electrodes in suitable conditions was performed by immersed in different concentrations (from 10-9M to 10-6M) of DA or EP in presence of 10-4 M of AA at pH 7. It was found that Poly(Cz) coated electrode was a more convenient biosensor for determination of EP by EIS method than Poly(In) and for DA determination. Also, the EIS method was able to use as the readout of Poly(Cz) coated electrode as a biosensor for the determination of EP.

In this study, the morphology and spectroscopic properties of polypropylene (PP)/
polyethyleneterephthalate (PET) blends were investigated by PET addition to improve the mechanical
properties of polypropylene. For the morphological characteristics of the PP + PET blends, SEM
analysis for the spectroscopic properties and FT-IR analysis were performed. As the percentage of the
mixture increases in the SEM images, there is a gap between the PET and the structure depending on
the addition ratio. In the PP + 40% PET mixture, the transition from droplet form to fibril form appears
clearly in the structure.

In this study we have tried to compare the results obtained by Microsoft Excel Solver program with those of NCSS and SPSS in some nonlinear regression models. We fit some nonlinear models to data present in http//itl.nist.gov/div898/strd/nls/nls_main.shtml by the three packages. Although EXCEL did not succeed as well as the other packages, we conclude that Microsoft Excel Solver provides us a cheaper and a more interactive way of studying nonlinear models.
Masculinity and Autonomous Vehicles
Authors: Balkmar Dag , Mellström Ulf
Published: March 2018

This article addresses the anthropomorphization and interpellative experience
of cars and trucks, in order to meet future mobility challenges. Autonomous
vehicles offer an emancipatory opportunity within a wider movement
of degendering and regendering motor vehicles. We argue that autonomous
vehicles can challenge the foundations of a gendered economy founded on
masculinity, speed, pleasure, and embodiment. Rather than thinking in terms
of a process of demasculinization, this article anticipates a regendering and
resegregation through which certain forms of masculine gendered economies
of pleasure will lose ground and others will gain. A core question in this article
asks who will be in the driver’s seat of future systems of automobility as the
control of the vehicle is gradually being transferred from the driver to digital
control systems and intelligent roads.
Media Ecologies of Autonomous Automobility
Authors: Hildebrand Julia M. , Sheller Mimi
Published: March 2018

The imagination of automated automobility puts into question the control of
the vehicle by a masculine driver and potentially disturbs feelings of safety,
power, security, and freedom. Given that systems of automobility and communication
technology are already gendered and racialized in particular ways,
this article explores how recent “premediated” depictions of automated car
technologies reconfigure and reproduce the historically gendered and raced
representations, meanings, and practices of (auto)mobility. This inquiry employs
a media ecological approach within the qualitative analysis of two concept
car previews by Nissan and Volvo. Rather than a degendering of the driver,
we suggest a multiplication of gendered and racialized technologies of mobility
via several forms of hypermediation. We also explore how the autonomous
car continues to evoke utopian spatial metaphors of the car as sanctuary and
communicative environment while allaying fears of dystopian metaphors of
the vehicle as traffic trap, virtual glass house, and algorithmic target.

Mapping as Orientation, Support, and Aide-mémoire in Short-term Travel Courses
Authors: James Christopher M.
Published: March 2018

This essay addresses drawbacks to short-term study abroad courses offered at small liberal-arts colleges, as well as difficulties students encounter in such courses. These difficulties arise due to the extremely full itineraries that the course structure may seek to provide, which can become overly burdensome to students in terms of what they are able to process fully, and what they retain during the course and after the course is over. One avenue of possible amelioration of this difficulty, while not challenging the opportunity to expose students to a wide range of sites and course-topical material, is a reliance on mapping. In terms of pre-travel, the map serves as orientation, a setting of expectations for what will be seen. During the course, while onsite, students are able to use the supplemental materials offered on the interactive map better to understand their surroundings. After the course, revisiting the map, along with their course notes, photos, and journals, provides an essential aide-mémoire. Choosing potential sites for extensive mapping based on those sites students are least familiar with is a way, then, to maximize the map's impact on learning outcomes.
Reconciling Optical and Radio Observations of the Binary Millisecond Pulsar PSR J1640+2224
Authors: Vigeland Sarah J. , Deller Adam T. , Kaplan David L. , Istrate Alina G. , Stappers Benjamin W. , Tauris Thomas M.
Published: March 2018

Previous optical and radio observations of the binary millisecond pulsar PSR J1640+2224 have come to inconsistent conclusions about the identity of its companion, with some observations suggesting that the companion is a low-mass helium-core (He-core) white dwarf (WD), while others indicate that it is most likely a high-mass carbon–oxygen (CO) WD. Binary evolution models predict PSR J1640+2224 most likely formed in a low-mass X-ray binary based on the pulsar’s short spin period and long-period, low-eccentricity orbit, in which case its companion should be a He-core WD with mass about 0.35–0.39 M
⊙, depending on metallicity. If instead it is a CO WD, it would suggest that the system has an unusual formation history. In this paper we present the first astrometric parallax measurement for this system from observations made with the Very Long Baseline Array (VLBA), from which we determine the distance to be

. We use this distance and a reanalysis of archival optical observations originally taken in 1995 with the Wide Field Planetary Camera 2 on the Hubble Space Telescope (HST) to measure the WD’s mass. We also incorporate improvements in calibration, extinction model, and WD cooling models. We find that the existing observations are not sufficient to tightly constrain the companion mass, but we conclude the WD mass is >0.4 M
⊙ with >90% confidence. The limiting factor in our analysis is the low signal-to-noise ratio of the original HST observations.
The Turbulence Magnetic Helicity Signature in the Interplanetary Medium: A Blackman–Tukey and Morlet Wavelet Analysis
Authors: Vasquez Bernard J. , Markovskii S. A. , Smith Charles W.
Published: March 2018

Interplanetary turbulence shows a spectral magnetic helicity signature whose properties could depend on the nature and dissipation of proton-scale fluctuations. A database of Wind spacecraft intervals of turbulence and helicity signatures is evaluated. Spectra are computed by both the Blackman–Tukey method and the Morlet wavelet method. A global mean magnetic field is used in each case, and the wavelet spectrum is averaged over time to facilitate comparison with the Blackman–Tukey spectrum. The maximum magnitude of the signature normalized by the trace of the magnetic spectral power has a frequency that correlates well between the two methods. The sign of the signature is also the same with both approaches, but the magnitudes differ. Statistically, the mean magnitudes of each method do agree, and the difference of individual magnitudes is assigned to uncertainties within each method. The Morlet wavelet method obtains fewer noisy signatures with a tighter overall correlation between magnetic helicity and cross-helicity; however, no trend is confirmed between helicity and the ratio of plasma to magnetic pressure. Subdivision of the analyzed intervals establishes that the helicity signature is persistent but variable. A portion of the variability comes from cross-helicity and possibly from the cascade rate. The observed magnetic helicity is compared to model and simulation results. Two-dimensional hybrid simulations yield results for the magnetic helicity magnitude that are larger than the mean values observed under similar conditions.
Exploring the Effects of Disk Thickness on the Black Hole Reflection Spectrum
Authors: Taylor Corbin , Reynolds Christopher S.
Published: March 2018

The relativistically broadened reflection spectrum, observed in both AGN and X-ray binaries, has proven to be a powerful probe of the properties of black holes and the environments in which they reside. Emitted from the innermost regions of the accretion disk, this X-ray spectral component carries with it information not only about the plasma that resides in these extreme conditions, but also the black hole spin, a marker of the formation and accretion history of these objects. The models currently used to interpret the reflection spectrum are often simplistic, however, approximating the disk as an infinitely thin, optically thick plane of material orbiting in circular Keplerian orbits around the central object. Using a new relativistic ray-tracing suite (Fenrir) that allows for more complex disk approximations, we examine the effects that disk thickness may have on the reflection spectrum. Assuming a lamppost corona, we find that finite disk thickness can have a variety of effects on the reflection spectrum, including a truncation of the blue wing (from self-shadowing of the accretion disk) and an enhancement of the red wing (from the irradiation of the central “eye wall” of the inner disk). We deduce the systematic errors on black hole spin and height that may result from neglecting these effects.

Thermal-dominated X-ray spectra of neutron stars in quiescent, transient X-ray binaries and neutron stars that undergo thermonuclear bursts are sensitive to mass and radius. The mass–radius relation of neutron stars depends on the equation of state (EoS) that governs their interior. Constraining this relation accurately is therefore of fundamental importance to understand the nature of dense matter. In this context, we introduce a pipeline to calculate realistic model spectra of rotating neutron stars with hydrogen and helium atmospheres. An arbitrarily fast-rotating neutron star with a given EoS generates the spacetime in which the atmosphere emits radiation. We use the Lorene/nrotstar code to compute the spacetime numerically and the Atm24 code to solve the radiative transfer equations self-consistently. Emerging specific intensity spectra are then ray-traced through the neutron star’s spacetime from the atmosphere to a distant observer with the Gyoto code. Here, we present and test our fully relativistic numerical pipeline. To discuss and illustrate the importance of realistic atmosphere models, we compare our model spectra to simpler models like the commonly used isotropic color-corrected blackbody emission. We highlight the importance of considering realistic model-atmosphere spectra together with relativistic ray-tracing to obtain accurate predictions. We also insist upon the crucial impact of the star’s rotation on the observables. Finally, we close a controversy that has been ongoing in the literature in the recent years, regarding the validity of the Atm24 code.
The genome structure of Arachis hypogaea (Linnaeus, 1753) and an induced Arachis allotetraploid revealed by molecular cytogenetics

Peanut,Arachishypogaea(Linnaeus, 1753) is an allotetraploid cultivated plant with two subgenomes derived from the hybridization between two diploid wild species,A.duranensis(Krapovickas & W. C. Gregory, 1994) andA.ipaensis(Krapovickas & W. C. Gregory, 1994), followed by spontaneous chromosomal duplication. To understand genome changes following polyploidy, the chromosomes ofA.hypogaea, IpaDur1, an induced allotetraploid (A.ipaensis×A.duranensis)4xand the diploid progenitor species were cytogenetically compared. The karyotypes of the allotetraploids share the number and general morphology of chromosomes; DAPI+bands pattern and number of 5S rDNA loci. However, one 5S rDNA locus presents a heteromorphic FISH signal in both allotetraploids, relative to corresponding progenitor. Whilst forA.hypogaeathe number of 45S rDNA loci was equivalent to the sum of those present in the diploid species, in IpaDur1, two loci have not been detected. Overall distribution of repetitive DNA sequences was similar in both allotetraploids, althoughA.hypogaeahad additional CMA3+bands and few slight differences in the LTR-retrotransposons distribution compared to IpaDur1. GISH showed that the chromosomes of both allotetraploids had preferential hybridization to their corresponding diploid genomes. Nevertheless, at least one pair of IpaDur1 chromosomes had a clear mosaic hybridization pattern indicating recombination between the subgenomes, clear evidence that the genome of IpaDur1 shows some instability comparing to the genome ofA.hypogaeathat shows no mosaic of subgenomes, although both allotetraploids derive from the same progenitor species. For some reasons, the chromosome structure ofA.hypogaeais inherently more stable, or, it has been at least, partially stabilized through genetic changes and selection.

Published: March 2018

Mapping and Assessment of Ecosystems and their Services (MAES) are central to the EU Biodiversity Strategy to 2020. Action 5 of the Strategy’s second target asks all EU member states to map and assess the state of ecosystems and their services in their national territories. Such comprehensive mapping and assessment builds on several individual tasks and their systematic integration. Therefore, an integrated and operational framework is needed, supporting and coordinating these activities. The presented framework builds on existing work done by the European Commission’s MAES Working Group and provides a clear nine-step approach including the identification of relevant questions or themes to be addressed, identification and mapping of ecosystem types, ecosystem condition and ecosystem services, their integration and dissemination of results. This framework can be used to set-up related research and development initiatives and to guide involved scientists, decision-makers and practitioners through the different steps and related tasks of the process.
Breeding biology of Tyrannus melancholicus (Aves: Tyrannidae) in a restinga reserve of southeastern Brazil

Published: March 2018

Existing knowledge of the breeding success and life history characteristics of most Neotropical bird species is scarce. Here, we help fill this gap by analyzing aspects of the breeding biology of the Tropical KingbirdTyrannusmelancholicus(Vieillot, 1819), which is a good model for this kind of study as it is a common species occurring in various environments, including urban areas, but little is known about its life history. We provide results concerning the breeding period, clutch size, incubation and nestling periods, description of nests, eggs and nestlings, and the plants used for nest sites by this species. Fifty-four nests were monitored over two seasons (2012–2014) in a protected area in southeastern Brazil. Nesting began at the end of the dry season and the beginning of the rainy season. The frequency of active nests varied according to variations in rainfall for each breeding season analyzed. The means and standard deviations of the incubation period (14.2 ± 1.9 days), nestling period (15.1 ± 0.8 days) and clutch size (2.5 ± 0.7 eggs) were similar to values reported for other Neotropical passerines. Twenty-one plant species used as nest trees and for the construction of the nests were identified. The results show thatT.melancholicusis not highly selective when choosing plant species used for nest construction.
Du paganisme au christianisme en Normandie occidentale ( iv e - v e siècles) : premiers éléments de synthèse
Authors: Roupsard Mathilde
Published: March 2018

Cet article reprend une étude de synthèse effectuée pendant deux années dans le cadre d’un travail universitaire. Il porte sur la période de transition entre le paganisme et le christianisme comprise entre le iv e et le vi e  siècle. À partir d’une analyse croisée de sources de natures variées, plusieurs thématiques ont pu être abordées : la chronologie de la transition entre le paganisme et le christianisme, l’étude architecturale et fonctionnelle des lieux de culte, et enfin, l’environnement d’implantation des sites cultuels et funéraires. Cela a permis d’établir des conclusions sensiblement différentes des postulats dominants jusqu’à maintenant. Le schéma d’un désintérêt progressif et largement pacifique du paganisme dès le iii e  siècle a été dégagé. Parallèlement, l’implantation très progressive, superficielle et largement urbaine du christianisme, en grande partie sous l’impulsion des premiers clercs, soutenus par l’autorité royale, a pu être observée tout au long de la période considérée.

Retour sur le parcours d’Eugène Maës, promoteur de sports aquatiques à Caen
Authors: Auvray Emmanuel
Published: March 2018

À Caen, le nouveau Stade nautique nouvellement dénommé, en 2014, Eugène Maës (1890-1945) pose la question de l’histoire locale du développement des sports aquatiques et de la mémoire collective de ceux qui ont fréquenté l’établissement « Chez Maës, Au Lido ». Cette étude historique vise donc à identifier les éléments du cheminement biographique d’Eugène Maës qui, d’une guerre à l’autre, ont conduit le conseil municipal de Caen à adopter ce choix pour honorer la mémoire d’un animateur de la vie sociale et sportive caennaise mort en déportation en 1945. Eugène Maës, footballeur de renom, a amorcé localement le développement de la natation sportive et du water-polo, contribué à sauver des vies en apprenant à nager à de nombreuses personnes, favorisé, dans le tissu associatif local, les conditions d’un brassage social par le biais de manifestations spectaculaires et originales, et enfin, permis aux Caennais de venir danser et écouter du jazz dans son café-dancing « Au Lido ». Ce choix constitue aussi un acte politique républicain contre l’oubli des victimes du nazisme.

Published: March 2018

Purpose: The integrated management system concept has  been installed recently in Algerian companies. A theoretical model is proposed which is based on a functional analysis of the systemic approach. This model is a cycle of seven requirements (organization context, leadership, planning, support, implementation of operational activities, performance evaluation and improvement), in addition to the inputs and outputs. The purpose of this article is to investigate the current status of integrated management system and test its performance in Algerian CompaniesDesign/methodology/approach: In order to achieve this objective, a survey based on 250 companies, only 115 of them responded to the survey where half of them are implementing IMS. A descriptive and an exploratory factor analysis (EFA) are provided. Additionally, the confirmatory Factor Analysis (CFA) the correlation and the regression analyzeFindings: From the results, the research reflects the status of IMS in Algeria. The findings suggest that the Algerian company have difficult to implementing the IMS.  Research limitations/implications: One of the major limitations of this study is the small simple size, which precludes generalization of the findings. This study provides a starting point for further research in developing countries.Originality/value: This paper offers  first key insights into IMS implementation in Algeria. This will encourage these organizations and developed countries in adopt IMS.
Vehicular Hyperthermia—A Highly Preventable and Potentially Fatal Problem
Authors: Dowd M. Denise
Published: March 2018

A child dying of heat injury due to being left unattended in a motor vehicle is a needless tragedy. Each year in the United States an average of 38 children mostly younger than age 2 years die of vehicular hyperthermia, frequently the result of a parental lapse of attention and not intentional neglect. Serious illness results quickly from exposure to rising heat within the passenger compartment, even on days when the temperature is fairly moderate. Prevention is paramount in addressing this problem and can best be accomplished by a combination of technological means, such as passive warning systems, laws that make leaving a child in a car alone illegal, and public education campaigns.

Acute Pediatric Pain Management in the Primary Care Office
Authors: Villacres Sindy , Chumpitazi Corrie E.
Published: March 2018

Pain is a chief complaint in children seeking medical care, yet it may also be experienced in evaluation and treatment during office visits. Inadequate relief of children's procedural pain and distress not only affects the experience of the children and their parents, but also adversely affects procedural outcomes. Despite increasing awareness and research, management of procedural pain and anxiety in children is often inadequate. In addition, parent and patient satisfaction is often tied to pain management. Development of a pain management plan must be systematic, individualized, and multimodal. We present a review of nonpharmacologic modalities, topical and oral analgesic agents, and intranasal adjuncts for use in routine outpatient practice.

Clavardage pédagogique : performances en écriture et interactions entre pairs chez des élèves du secondaire en difficulté d'apprentissage
Authors: Gonthier Marie-Ève , Ouellet Chantal , Lavoie Natalie
Published: March 2018

Bien que fort populaire chez les jeunes d'aujourd'hui, le clavardage semble peu utilisé en classe. Cet article fait état d'une recherche qualitative centrée sur l'utilisation du clavardage pédagogique en contexte d'écriture, dont les objectifs sont les suivants : 1) analyser et comparer un texte rédigé individuellement à l'ordinateur et un texte écrit en collaboration avec le clavardage, 2) analyser les interactions lors des séances de clavardage et 3) les mettre en lien avec les textes produits. Les scripteurs (N = 20) et leurs équipiers (N = 20), qui les ont soutenus avec le clavardage pour le second texte, sont des élèves en difficulté de première et de deuxième secondaire (12-14 ans). Les textes ont été analysés d'après différents critères et les interactions ont été classées dans des catégories. Il a aussi été vérifié dans quelle mesure les propositions des pairs ont été transférées dans les textes. Grâce au clavardage, les jeunes des deux niveaux ont mieux réussi à certains critères d'évaluation (orthographe grammaticale, respect des consignes et construction des phrases). Les interactions cognitives centrées sur la tâche dominent dans leurs discussions ; d'ailleurs, ils ont pris en compte plus de la moitié des propositions discutées. En somme, les jeunes ayant un intérêt certain pour le clavardage, il demeure judicieux d'y faire appel afin d'écrire en classe.
Challenges and Enablers for Rapid Product Development
Authors: Verrollot Jordan , Tolonen Arto , Harkonen Janne , Haapasalo Harri J. O.
Published: March 2018

This article describes how new product development (NPD) is critical to maintaining a strong market position. However, full-scale NPD may consume too much time and resources when necessary to react quickly to customer needs or emerging business opportunities. Rapid development (RaDe) is a type of incremental product development complementing the organizations' existing NPD process. In RaDe, new sales items are created by redesigning or upgrading existing products inexpensively, and in a timely manner. This article aims at clarifying the challenges and enablers relating to RaDe implementation in four case companies and by the means of reviewing literature. The identified challenges include the difficulty of differentiating between product developments models, the lack of clear definition for RaDe and issues in product data management. The enablers include structuring and managing projects differently compared to NPD, the utilization of existing supply-chain capabilities and the designed products fitting the current business processes to enable rapid product ramp-ups.

Authors: Jalali Moeen Sammak , Ghomi S.M.T. Fatemi
Published: March 2018

This article describes how simplifying production-planning approaches for demand responsiveness has been well recognized as an operative means of accomplishing production efficiency. To support an effective decision making in manufacturing environments, this study will focus on adopting time series analysis concepts. It will attempt to focus on bringing forward novel structures for classifications of available surveying materials, which helps companies using time series analysis within production strategies to make a logical prediction of demands in hybrid manufacturing systems. In this regard, the authors will present two different categorizing structures as efficient ways of helping practitioners and academicians to find new approaches for applying near possible future forecasts by means of time series analysis methods.

Furthermore, design reliability evaluation which is a key component of product development engineering processes is studied by reflecting and providing guidance on how to sort and assess reliability information early at the product design stage, as well as how to account for flexibility and expert's attitudinal character (information), which have been found critical in the assessment of engineering products reliability.
Factors Influencing Teachers' Integration of ICT in Teaching and Learning
Authors: Lawrence Japhet E.
Published: March 2018

There is a growing demand on educational institutions to use ICT to teach the skills and knowledge students need for the digital age. The integration of ICT into education provides opportunities for teachers and students to work better in a globalized digital age, particularly in teaching and learning environment, where teaching and learning can take place anytime and anywhere, 24-hours seven days a week. The purpose of this article is to identify the factors that influence teachers' decision to integrate ICT in teaching and learning. The study is chosen because of the strategic importance of ICT in education and particularly, its immense potential, to transform the ways in which teaching is carried out in the classroom. There are a lot of studies in the area, but very little empirical research has been conducted to examine this phenomenon from the teachers perceptive. The present article aims to fill this gap by using in-depth case studies, conceptualized within the grounded theory method to develop a model that will explain and enhance the understanding of the factors influencing teachers' integration of ICT in teaching and learning. The diffusion theory will provide the theoretical foundation for this study.

Published: March 2018

This article describes how the enormous potential benefits provided by the cloud services, made enterprises to show huge interest in adopting cloud computing. As the service provider has control over the entire data of an organization stored onto the cloud, a malicious activity, whether internal or external can tamper with the data and computation. This causes enterprises to lack trust in adopting services due to privacy, security and trust issues. Despite of having such issues, the consumer has no root level access right to secure and check the integrity of procured resources. To establish a trust between the consumer and the provider, it is desirable to let the consumer to check the procured platform hosted at provider side for safety and security. This article proposes an architectural design of a trusted platform for the IaaS cloud computing by the means of which the consumer can check the integrity of a guest platform. TCG's TPM is deployed and used on the consumer side as the core component of the proposed architecture and it is distributed between the service provider and the consumer.
