Published: May 2017

Since the last century, we have witnessed a steady evolution of advertising techniques in an effort to adapt to the new social context in the market. As a strategic resource, Neuroscience brings a new perspective by allowing you to explore those difficult or verbally unconscious motives behind consumer behaviours. The present work aims to discover the relationship between the emotions induced in audiovisual advertising messages and their impact on the memory of the subjects. To achieve this goal, an experiment was carried out with eight audiovisual advertising messages (six representatives of the basic emotions: joy, surprise, anger, disgust, fear and sadness, and two rational ones that show the technical specifications of the product). Neuromarketing techniques such as the electrical activity of the heart (ECG) and the electrodermal activity (EDA) of the subjects are used, on one hand; and, on the other, a conventional research technique, a questionnaire applied to the subjects that participated in the research. The results show variations in the measures performed in the commercials corresponding to joy, surprise and anger, while for both, remembrance of the message transmitted and activity of the advertiser, the commercial with the best results has been the one regarding sadness, advertisement that has also been considered the most attractive for participating subjects.

Desde el siglo pasado hemos presenciado una evolución constante de las técnicas de comunicación publicitarias en un intento de adaptación a las nuevas realidades sociales del mercado. Como recurso estratégico, la Neurociencia aporta una nueva perspectiva al permitir explorar aquellos motivos difíciles de verbalizar o inconscientes que hay detrás de los comportamientos de los consumidores. El presente trabajo tiene como objetivo descubrir la relación entre las emociones inducidas en los mensajes publicitarios audiovisuales y su impacto en el recuerdo de los sujetos. Para alcanzar este objetivo se ha realizado un experimento con ocho mensajes publicitarios audiovisuales (seis representativos de seis emociones básicas: alegría, sorpresa, ira, asco, miedo y tristeza; y dos racionales) en el que se han utilizado, por un lado, técnicas de Neuromarketing como son la actividad eléctrica cardíaca (ECG) y la actividad eléctrica de la dermis (AED) de los sujetos; y, por otro, una técnica de investigación convencional, un cuestionario aplicado a los sujetos que han participado en la investigación. Los resultados ponen de manifiesto variaciones en las medidas realizadas en los mensajes correspondientes a la alegría, la sorpresa y la ira, mientras que, tanto para el recuerdo sugerido del mensaje trasmitido como para la actividad del anunciante, el anuncio con mejores resultados ha sido el de la tristeza, anuncio que también ha sido considerado el más atractivo para los sujetos participantes.

Authors: Romero-Martín Rosario , Castejón-Oliva Francisco-Javier , López-Pastor Víctor-Manuel , Fraile-Aranda Antonio
Published: May 2017

The purpose of this study is to analyze the perception of students, graduates, and lecturers in relation to systems of formative and shared assessment and to the acquisition of teaching competences regarding communication and the use of Information and Communications Technology (ICT) in initial teacher education (ITE) on degrees in Primary Teaching Physical Education (PTPE) and Physical Education and Sports Science (PESS). An ad hoc questionnaire was applied to a total sample of 1,243 students, 487 graduates and 345 lecturers from 24 Spanish universities that cover most of Spain’s Regional Autonomous Communities. The results from the questionnaires indicate that for all three groups the most relevant element in the assessment process is the teacher-student interaction, and the second most relevant are the competences in interpersonal relationships. Significant differences are also found in practically all the items in the questionnaire between the responses of lecturers and students and between those of students and graduates. In our detailed study of the perceptions of students regarding their competence in ICT, those taking the degree in PTPE perceive a greater use of ICT than those taking the degree in PESS. The same difference was found with students under 22 years of age in relation to the older students. No gender differences were found.

La finalidad de este estudio es analizar la percepción del profesorado, alumnado y egresados en relación a los sistemas de evaluación formativa y compartida y a la adquisición de competencias docentes respecto a la comunicación y al uso de las TIC, en la formación inicial en el Grado de Maestro de Primaria (Educación Física) y en el Grado en Ciencias de la Actividad Física y el Deporte (CCAFD). Se ha aplicado una escala diseñada «ad hoc» en una muestra total de 1.243 estudiantes, 487 egresados y 345 profesores de 24 Universidades españolas que abarcan la mayoría de las Comunidades Autónomas. Los resultados indican que para los tres colectivos el elemento más relevante en el proceso de evaluación es la interacción profesores-estudiantes y, en segundo lugar, las competencias en relaciones interpersonales. También que existen diferencias significativas en prácticamente todos los ítems entre los profesores y los estudiantes y entre estos y los egresados. En el estudio pormenorizado de la percepción de las competencias TIC por parte de los estudiantes, los procedentes del Grado de Maestro de Primaria perciben una mayor utilización de las TIC que los de CCAFD; lo mismo ocurre con los menores de 22 años en relación a los más mayores. No se han encontrado diferencias en función del género.
Analyse rétrospective du respect des nouveaux critères de convergence de l’UEMOA
Authors: Diarra Souleymane
Published: May 2017

Les États de l’UEMOA ont adopté en 2015 de nouveaux critères de convergence. Cet article présente une analyse rétrospective pour la période 2000-2014 en s’intéressant principalement au critère de solde budgétaire, qui constitue le changement majeur du nouveau pacte. Il mesure le respect de l’ancien critère de solde budgétaire et cherche à savoir quel aurait été celui du nouveau critère selon la méthode de sigma convergence. Il ressort que le nouveau critère de solde budgétaire présente une moindre exigence pour les États que l’ancien critère. Cependant, le niveau de respect du nouveau critère, les projections sur ce dernier et les conditions exigées pour rentrer en phase de stabilité montrent qu’il sera difficile de converger à l’horizon 2019.

Non, je ne reprendrai pas cet article. Quelques remarques complémentaires sur la fonction développementale du « non »
Authors: Marcelli Daniel
Published: May 2017

Autant l’enfant dit « non » facilement, autant aujourd’hui les parents semblent entravés dans leur possibilité de dire « non » à leur enfant. Cet article, reprise d’un précédent travail, décrit l’évolution développementale du « non » de l’enfant, particulièrement complexe car le « non » confond à la fois celui de l’opposition/différenciation et celui de l’identification au parent interdicteur. Affirmation paradoxale de soi, le premier a gagné ses lettres de noblesse quand le second semble dévalorisé, témoin supposé d’une dimension autoritaire et hiérarchique de l’éducation. Dans ce contexte, il reste à savoir comment l’être humain peut se dégager d’une compulsion systématique à dire « non » ! L’auteur émet l’idée que le « je » de la subjectivité est bien sûr lié au « non » au travers des jeux de faire semblant et que le « oui » de l’acceptation (et non pas le « oui » de la soumission) traduit la capacité de ce « je » à dire « non » à son propre « non », en un mot accéder à la possibilité de consentir, marque de la plénitude subjective !
Quand surgit l’opposition : le stade anal
Authors: Chapellon Sébastien , Gadio Guéda
Published: May 2017

Durant le stade anal, l’enfant éprouve un pressant besoin de s’opposer aux adultes. En transgressant leurs règles, il cherche à construire son autonomie psychique. Celle-ci passe en partie par le rejet des parents qui l’ont fait grandir lorsqu’il était bébé. Le lien fusionnel qui s’est créé au stade oral revêt un caractère envahissant. Au sortir de cette période, le petit enfant éprouve donc le besoin de rejeter ce mode de lien passé en s’opposant à ses parents. Cet article s’attache à décrire les manifestations de cette opposition et à en expliquer les causes.

Les apports de la sociohistoire à la compréhension du traitement des difficultés scolaires et des handicaps des élèves au sein de l’école en France (1904-2013)
Authors: Mazereau Philippe
Published: May 2017

En proposant une analyse conjointe des politiques publiques scolaire et médico-sociale, la perspective sociohistorique permet de renouer avec la genèse de la mise en forme sociale des questions liées à la catégorisation de l’efficience intellectuelle des jeunes scolarisés. La reconstruction de liens entre normes scolaires et désignations psychologiques des difficultés individuelles des élèves clarifie rétrospectivement les interactions entre les problématisations sociales de l’échec scolaire et la construction d’une politique publique du handicap. Pensé en termes de protection sociale, le handicap a réinterrogé la dépendance historique des catégorisations médicales par rapport à la normativité scolaire. L’affirmation européenne d’objectifs d’inclusion sociale, fondés sur la prééminence attribuée à la formation du capital humain, éclaire d’un jour inédit la mise en avant progressive des arguments économiques comme fondement principal des institutions scolaires.
Se situer parmi les pairs : des groupes affinitaires aux conflits. L’étude d’interactions dans une cour de récréation
Authors: Salaméro Émilie
Published: May 2017

Les enfants sont souvent appréhendés comme un groupe social homogène et leurs conflits ordinaires sont peu étudiés. Une enquête ethnographique menée pendant un an dans une école ariégeoise auprès d’une classe de CM2 permet de porter un regard plus attentif aux conflits entre filles et à leur rôle au sein des pairs, en tenant compte de la structure des relations sociales. Dans ce travail, les modalités de conduite des conflits sont reliées aux modes de socialisation des enfants et à leurs ressources sociales, analysées à partir des pratiques corporelles (activités ludiques et apparence corporelle) développées en cour de récréation. Cette étude met plus particulièrement au jour le rôle des dispositions agonistiques au sein des rapports sociaux enfantins et dans le processus de hiérarchisation des filles.
La forme intégrative : le cas des enseignements par projet
Authors: Baluteau François
Published: May 2017

Au sein de l’Éducation nationale, la prise en compte de la diversité des élèves (décrocheurs, en situation de handicap, etc.), la volonté d’intéresser les élèves comme celle de développer diverses compétences conduisent à varier les modalités pédagogiques. L’analyse porte sur le cas des enseignements conçus dans le cadre d’un projet, modalité qui tend à se développer depuis plusieurs années. Appuyé sur des entretiens compréhensifs avec des enseignants en exercice, de l’école maternelle au lycée, et sur leurs outils pédagogiques, l’article aborde l’organisation du savoir, le mode de socialisation, le rapport à l’environnement et l’organisation du travail entre les partenaires. Ces résultats permettent de proposer, en se fondant sur l’empirie, le concept de forme intégrative, en filiation avec les travaux de Guy Vincent et de Basil Bernstein.
Quand le savant devient politique. Sociologie de l’expertise du think tank Terra Nova
Authors: Argibay Camilo
Published: May 2017

Bien que la division du travail affichée par les think tanks tende à présenter le travail des experts comme apolitique, cet article propose de l’envisager comme une activité politique. Dans le cadre d’une enquête de terrain consacrée à Terra Nova, ce travail apparaît tout d’abord comme un exercice pour lequel les acteurs ont intériorisé la dimension politique de leur activité. Par les anticipations et les choix qu’ils opèrent, ils produisent du politique avant même que leurs recommandations soient endossées par un décideur public. Ensuite, il s’agit également d’une activité politique dans une seconde acception, en ce sens où la participation au think tank constitue une forme d’engagement politique pour les experts, avec des sociabilités et des rétributions qui lui sont attachées.

Authors: Odin Pierre
Published: May 2017

Cet article se propose de porter un regard croisé sur les tensions entre mobilisation et participation des publics, dans l’optique de questionner le cadre de la définition des problèmes publics durant une situation de conflit social généralisé – comme ce fut le cas en Guadeloupe en 2009. Interrogeant les effets du travail de coalition et les enjeux de la concurrence organisationnelle dans la mise en capacité stratégique des acteurs contestataires, il se propose de montrer comment des revendications issues de catégories militantes indigènes accèdent au rang de problème public. Il se propose également d’interroger les conditions de diffusion et de circulation des ressources critiques, au travers d’une approche compréhensive de la dimension conflictuelle du processus des négociations.
Swept-Source OCT Visualization of Macular Hole Closure in Gas-Filled Eyes
Authors: Li Daniel Q. , Choudhry Netan
Published: May 2017

BACKGROUND AND OBJECTIVE:

To assess the utility of swept-source optical coherence tomography (SS-OCT) in visualizing macular hole (MH) closure through gas-filled eyes on postoperative day (POD) 1 using a dual scanning protocol.

PATIENTS AND METHODS:

We examined 30 consecutive patients with full-thickness MH who underwent standard vitrectomy with SF6 (25%) gas tamponade between July 2015 and April 2016. SS-OCT imaging was performed using horizontal raster and 16-line radial scans with manual delicate focusing to evaluate MH closure status.

RESULTS:

On POD1, optically clear images with visualization of all retinal layers at the fovea were obtained in 80% of eyes, of which 71% achieved complete MH closure. Reasons for unsuccessful imaging included: hyphema (two eyes), dense cataract (two eyes), and gas meniscus interference (two eyes).

CONCLUSION:

SS-OCT with dual scanning protocol and manual delicate focusing enabled consistent early visualization of foveal architecture for assessment of MH closure through gas-filled eyes.

Adaptive Optics Scanning Laser Ophthalmoscopy and Multimodal Imaging of Peau D'Orange in Pseudoxanthoma Elasticum
Authors: Onishi Alex C. , Nesper Peter L. , Fawzi Amani A.
Published: May 2017

A 41-year-old male with pseudoxanthoma elasticum who presented with progressive vision loss in his left periphery is discussed. Bilateral angioid streaks, optic disc drusen, choroidal neovascularization, and peau d'orange were present. Imaging of the area with peau d'orange with adaptive optics scanning laser ophthalmoscopy and en face optical coherence tomography at Bruch's membrane (BM) revealed a pattern identical to the patches of peau d'orange visible with conventional fundus imaging techniques. These results show that structural abnormalities at the level of BM, likely a result of calcification, correlate with the characteristic “orange peel” pattern known as peau d'orange.

Authors: Salmela Erno , Vimm Ivary , Hirvimäki Marika , Juvonen Pasi
Published: May 2017

The purpose of this research was to find out what value rapid prototyping (RP) adds to innovation and creative activity, what challenges it entails, and what sort of innovation it is especially suited for. The research was implemented as a qualitative case study of ten cases. According to the study, RP is an important part of the innovation process regardless of its tinkering reputation. It opens up an innovation block, adds creativity, engages people, and helps to estimate the potential of idea´s originality and effectiveness. RP has a positive impact on people's work enjoyment due to its playful and communal nature. And anyone can participate. Therefore, the creativity is a matter of everybody. The main limitation of the research was examining RP as a static event in one phase of the innovation process. As practical value, this article encourages organisations to increase RP in their innovation activities.

VANETs are enhanced and upgraded versions of mobile ad-hoc networks which are fruitful for intercommunication vehicles. Communication can be vehicle-to-vehicle and between vehicles to side-fixed equipment known as roadside equipment. This network is self-organized, highly dynamic but separated without any infrastructure or client and server communication. The objective of this research is to examine the study of TwoRayGround and Nakagami radio propagation models for vehicular ad-hoc networks in Indian Scenarios as well as to find the best efficient model, which is more suitable in various scenarios. Output of this research will be beneficial for applying efficient models on the realistic highway scenario, especially traffic caused by four wheelers. This model will also be fruitful for avoiding heavy road congestion and highway road accidents caused by a high and unbalanced speed of traffic as well as other various road conditions, like pot holes and road barriers, etc.
An Incorporation of the Fuzzy Greedy Search Heuristic With Evolutionary Approaches for Combinatorial Optimization in Operations Management
Authors: Sheibani Kaveh
Published: May 2017

Although greedy algorithms are important, nowadays it is well assumed that the solutions they obtain can be used as a starting point for more sophisticated methods. This paper describes an evolutionary approach which is based on genetic algorithms (GA). A constructive heuristic, so-called fuzzy greedy search (FGS) is employed to generate an initial population for the proposed GA. The effectiveness and efficiency of the proposed hybrid method are demonstrated on permutation flow-shop scheduling as one of the most widely studied hard combinatorial optimization problems in the area of operational research.

Published: May 2017

This paper focuses on simulating environmental impacts on grapevine behavioral dynamics and vineyard management strategies. The methodology presented uses technology from geomatics object oriented databases and spatio-temporal data models. Our approach has two principle objectives, first, to simulate grapevine phenology and grape ripening under spatial and temporal environmental conditions and constraints and secondly, to simulate viticultural practices and adaptation strategies under various constraints (environmental, economical, socio-technical). The approach is based on a responsive agent-based structure where environmental conditions and constraints are considered as a set of forcing data (biophysical, socio-economic and regulatory data) that influences the modelled activities. The experiment was conducted in the regulated wine producing appellation Grand Cru “Quarts de Chaume”, situated in the middle Loire Valley, France. All of the methodology, from the implementation of the knowledge database to the analysis of the first simulation, is presented in this paper.
Production Planning Based on DEA Profit Efficiency Models
Authors: Liu Feng , Zhang Mengni
Published: May 2017

In this research, the authors propose DEA (data envelopment analysis) profit efficiency models for production planning which is one of important problems in the production and operations management. Different from traditional models, the constraint that the optimal output is supposed to be not less than the original one from the production possibility set is omitted in their developed no output constraint maximum profit (NOCMP) model. Besides, observing that output prices could be varied with the total market demand in the market, the researchers present the no output constraint maximum profit with varied output price (NOCMP-VOP) model. The authors apply these two DEA profit efficiency models to U.S. airline industry for illustration. The developed NOCMP and NOCMP-VOP models in this study contribute to developments of both the DEA profit efficiency model and its applications.

As a result, it improves the understanding of the relationship between organizational data and organizational goals that can lead to an effective evaluation of the goals achievement.
A Comparative Analysis of the Cyberattacks Against Estonia, the United States, and Ukraine
Authors: Boyte Kenneth J.
Published: May 2017

This comparative international case study of cyber warfare provides a context for considering the evolution of cyber technologies as elements of hybrid warfare capable of creating confusion, disrupting communications, and impacting physical infrastructure (such as power grids and satellite-based communications and weapons systems). Expanding an unpublished paper recognized by the ASIS Foundation in its 2012 international student writing competition concerning global security, which compared the cyberattacks against Estonia in 2007 and the United States in 2012, this study re-examines and updates the original data in a broader analysis that primarily includes the cyberattacks against Ukraine during the 2013-2015 conflict, but also considers other incidents on the timeline of digitization. The study shows how cyber warfare, first reported in the 1990s, has become an integral component of war today for both state and non-state actors who use zombies and robot armies to penetrate national boundaries and firewalls via satellites.
A Two-Dimensional Webpage Classification Model
Authors: Yang Shih-Ting , Huang Chia-Wei
Published: May 2017

Regarding the webpage classification topics, most classification mechanisms may lack of consideration from the webpage article writer's perspective and the display characteristics of the webpage (color, graphic layout). Hence, this paper develops a Two-dimensional Webpage Classification model to analyze the webpage textual information and display characteristics from the perspectives of webpage users and designers. This model is consisted of the Webpage Block Distribution Analysis (WBDA) module, Webpage Emotion Category Determination (WECD) module and Webpage Specialty Category Determination (WSCD) module. Firstly, in WBDA module, the user and designer habits (such as the web browsing movement and the writing perspective of webpage) should be considered by combining with the eye movement tracking and tag-region judgment to determine the critical blocks and information of the webpage. Secondly, in WECD module, the webpage color codes are acquired to calculate the major colors of the webpage, and further determine the emotional category of webpage. Thirdly, the WSCD module analyzes the webpage textual information by integrating the keyword acquisition technology to identify the specialty category of the webpage. After that, the Two-dimensional category of the webpage can be obtained. In addition, this paper develops a web-based system accordingly for case verification to confirm the feasibility of the methodology. The verification results show that firstly for webpage emotion category judgment when 128 webpage files for training are imported into this system, the respondent's emotion evaluation score is increased to above Level 5 and the system recommendation success rate is increased to 75.78%. Secondly, for specialty category determination, when system uses 1010 to 1120 webpage files for training, the system performance can be increased to above 80%. Hence, the developed system has a high-performance level in webpage emotion category and specialty category determination. That is, this paper proposes a methodology of Two-dimensional Webpage Classification to classify the webpage file information contents and the effects on the emotions of the demanders to assist webpage providers in providing webpage suitable for demanders with the generated two-dimensional information of the webpage.

Functional Link Neural Network with Modified Artificial Bee Colony for Data Classification
Authors: Herawan Tutut , Hassim Yana Mazwin Mohmad , Ghazali Rozaida
Published: May 2017

Functional Link Neural Network (FLNN) has emerged as an important tool for solving non-linear classification problem and has been successfully applied in many engineering and scientific problems. The FLNN structure is much more modest than ordinary feed forward network like the Multilayer Perceptron (MLP) due to its flat network architecture which employs less tuneable weights for training. However, the standard Backpropagation (BP) learning uses for FLNN training prone to get trap in local minima which affect the FLNN classification performance. To recover the BP-learning drawback, this paper proposes an Artificial Bee Colony (ABC) optimization with modification on bee foraging behaviour (mABC) as an alternative learning scheme for FLNN. This is motivated by good exploration and exploitation capabilities of searching optimal weight parameters exhibit by ABC algorithm. The result of the classification accuracy made by FLNN with mABC (FLNN-mABC) is compared with the original FLNN architecture with standard Backpropagation (BP) (FLNN-BP) and standard ABC algorithm (FLNN-ABC). The FLNN-mABC algorithm provides better learning scheme for the FLNN network with average overall improvement of 4.29% as compared to FLNN-BP and FLNN-ABC.
Factors Affecting Willingness of Industries to Adopt Radio Frequency Identification (RFID)
Authors: Kohli Amarpreet S. , Peng Cheng
Published: May 2017

This research examined the willingness of businesses and industries to adopt RFID. It was postulated that motivation to adopt RFID is influenced by the technological context, organizational factors, and perceived benefits of using RFID. Data was collected from Council of Supply Chain Management Professionals members using a 19-question web-based survey. Relative advantage that firms can achieve and the perceived benefits in improving product quality and information sharing along with better traceability in the supply chain were significant predictors of RFID adoption. Within the technological contexts, the visible obstacles of RFID adoption through quality of transmission and reliability, understanding of overly high investment costs, and importance of the privacy concerns were all significant. The IT readiness of a firm was also a significant predictor of RFID adoption in the organizational factor, however the size of an organization was not at all linked to the RFID adoption decisions. The results point to a number of important conclusions that are informative for various business and industries that might be contemplating to adopt RFID technology in their operations.

Authors: Okdinawati Liane , Simatupang Togar M. , Sunitiyoso Yos
Published: May 2017

Collaborative Transportation Management (CTM) is a collaboration model in transportation area. The use of CTM in today's business process is to create efficiency in transportation planning and execution processes. However, previous research paid little attention to demonstrate the ability for all agents in CTM to co-create value in services. The purpose of this paper is to increase the understanding of value co-creation in CTM area and learning processes in real systems based on value co-creation of CTM. Multiple case studies were used to analyze the value that was perceived by all agents in CTM in each collaboration stage and provided empirical evidence on the interactions among agents. Model-free reinforcement learning was used to predict how CTM could reduce transportation cost, increase visibility, and improve agility. The simulation results show that the input, feedback, and the experience of the agents are used to structure the collaboration processes and determine the strategies.
Unsettling Trends in Academia: A Review of the Predicament of Minorities and Members of the LGBTQ Community in Higher Educational Institutions in America
Authors: Cascio Payal Dev
Published: May 2017

The current sociopolitical climate of the country (USA) is tumultuous and volatile. It is an era that recognizes and strives for change and open dialogue on topics that have otherwise been brushed under the rug. Such times call for open discussions on topics that may also be tabooed and bear a sense of unease and discomfort. Under this umbrella of racy and risky times emerged this study on the lived experiences and occurrences that have negatively impacted members of ethnic minorities and LGBTQ communities within academia. As an intellectual field that prides itself on its intensive research rigor and vitality, academia can no longer overlook this subject of workplace bullying in academia among faculty, staff, and students whose bullied experiences need to be addressed and shared by the main stream population so we can all move forward together and seek to find a resolve to the existing atrocities that the members from these minority groups currently face.

Quality in Use Analysis to Evaluate User Experience of Open Source Software Compatible with MATLAB
Authors: Abu Talib Manar
Published: May 2017

Mathematical and statistical open source software (OSS) has played a vital and positive role in computing statistics, performing numerical computations, and solving for real and complex scalars. There is an enormous need to apply quality models to this type of software. In this paper, we present an inclusive set of current quality models and demonstrate their application to OSS. As very little research has been carried out on the quality in use assessment of mathematical software, this work investigates the application of the quality in use model inspired by ISO/IEC 25010 on three OSS products: Scilab, R-Language, and GNU Octave. We can confidently state that Scilab, R-Language, and GNU Octave perform similarly in terms of effectiveness, efficiency, productivity, and cognitive load. However, Scilab outperforms GNU Octave slightly when it comes to error safety.
An Exploratory Study of Conflict over Paying Debian Developers
Authors: Gerlach James H. , Wu Chorng-Guang , Cunningham Lawrence F , Young Clifford E
Published: May 2017

This article reports on an exploratory study of the causes and effects of conflict within the open source software project, Debian. Conflict arose when the project leader decided to introduce payment for select volunteers within an all-volunteer project to speed up the release of Debian. The study utilized the theoretical framework of Boltanski and Thévenot for understanding disputes. The results of the survey of Debian developers show that the conditions for conflict were complex and were driven by perception of misuse of authority, ideology, feeling of inequity, and satisfaction with pay for their regular job. The effects of the conflict were shown to be pervasive as it affected volunteer's citizenship behaviors and withdrawal from the project. Additionally, the conflict led some developers to reaffirm their beliefs about the value of paying volunteers. The conclusions of the study offer insight into the issues of incentivizing volunteer OSS developers.

This study classified the vegetation of the Savuti-Mababe-Linyanti ecosystem (SMLE), northern Botswana and developed a detailed map that provides a reliable habitat template of the SMLE for future wildlife habitat use studies. The major vegetation units of the SMLE were determined from satellite imagery and field visits and then mapped using Landsat 8 and RapidEye imagery and maximum likelihood classifier. These units were sampled using 40 m x 20 m (800 m²) plots in which the coverage of all plant species was estimated. Non-metric multidimensional scaling (NMS) demonstrated that plant communities were determined by gradients in soil texture or fertility and wetness. NMS 1 represented a gradient of soil texture with seven woodland communities on sandy soils (sandveld communities and Baikiaea forest) dominated by Baikiaea plurijuga in Baikiaea forest and Terminalia sericea and Philenoptera nelsii in sandveld, with various indicator species differentiating the various sandveld community types. Mopane woodland further from and riparian woodland adjacent to permanent water was common on less sandy alluvial soils. Mineral-rich, heavy clay soils in the sump of a large paleolake system support open grassland and mixed Senegalia/Vachellia (Acacia) savanna, with the mineral-rich soils supporting grasses high in minerals such as phosphorus, calcium, sodium and potassium, and thus this region is a critical wet season range for migratory zebra. Taller, high-quality grasses in the mosaic of sandveld and mopane woodland communities provide critical grazing for taller grass grazers such as buffalo, roan and sable antelope, whereas wetland communities provide reliable green forage during the dry season for a variety of herbivores, including elephant. This study has demonstrated how large-scale environmental gradients determine functional habitat heterogeneity for wildlife.Conservation implications: Our study demonstrated that the functionality of protected areas is determined by large-scale environmental gradients. Thus conservation science must aim to ensure that protected areas cover the full range of key environmental gradients in a region (soil texture and wetness in our study). Our habitat map provides a data base for wildlife habitat use studies in the region.

Environmental heterogeneity across savanna landscapes, including different seasonal resources at different distances to water, may play a critical role in maintaining the size and diversity of wildlife populations and the sustainability of their resource base. We investigated whether extensive landscapes with functionally diverse seasonal resources and large waterless regions can mediate the effect of herbivory on plant composition, structure and diversity. Vegetation composition, structure and richness in two different vegetation types (mopane and sandveld woodland) at three distance zones (0 km – 5 km, 10 km – 15 km and > 20 km) from the permanent water of the Okavango Delta and Linyanti Swamps were surveyed. We modelled vegetation response of the most abundant species to herbivory in relation to distance from permanent water, and included fire frequency as a covariate. Trees favoured by elephants during the dry season occurred typically as immature, pollarded populations within 5 km of permanent water sources while mature tall populations of these species were found far from water (> 10 km – 15 km). Similarly, short high-quality grazing grasses were higher in abundance within 5 km of permanent water, whereas taller high-quality perennial grasses peaked in abundance beyond 20 km from permanent water. Trends in herbaceous richness with distance from water were contingent upon vegetation type, while tree richness did not change with distance from water. Spatial refuges in waterless regions of landscapes facilitate the creation of heterogeneity of vegetation structure, composition and richness by large herds of mammalian herbivores. Therefore, the extension of herbivore dry season foraging range, for example, by the creation of artificial water points (AWP) in backcountry woodlands, could seriously undermine the resilience of landscapes to herbivory by reducing the availability of spatial refuges. Consequently, it reduces the resilience of herbivore and predator populations that depend on these spatial refuges. We strongly advise that future scientific work, and management and policy actions should be focused on the identification and sustaining of these spatial refuges in wildlife areas.Conservation implications: Management and policy actions should be focused on the identification and sustainability of spatial refuges in wildlife areas. Too many AWP in backcountry woodlands could undermine the resilience of landscapes to herbivory by reducing the proportion of landscapes beyond 15 km from permanent water.

Existence of stationary solutions for some integro-differential equations with superdiffusion
Authors: Vougalter Vitali , Volpert Vitaly
Published: May 2017

The work deals with the existence of solutions of an integro-differential equation arising in population dynamics in the case of anomalous diffusion. The proof of existence of solutions relies on a fixed point technique. Solvability conditions for non-Fredholm elliptic operators in unbounded domains are being used.
Accuracy of Working Length Determination using NovApex and Root-ZX Apex Locators: An in vitro Study

Introduction

Thisex vivostudy evaluated the accuracy of the Root-ZX electronic apex locator (EAL) (J. Morita, Tokyo, Japan) and the NovApex (Forum Technologies, Rishon Lezion, Israel) in determining the working length (WL) during endodontic treatment.

Materials and methods

Forty extracted single-rooted human teeth were selected for this study. The actual WL was measured with visual technique by a size #15 k-file under magnification. Then, the canal lengths were measured electronically with both Root-ZX and NovApex apex locators within ±0.5 and ±1 mm. Mean percentage of data was analyzed between groups using paired t-test, with a statistically significant level of p < 0.05.

Results

The accuracy of NovApex apex locator was 85% within ±0.5 mm and 92.5% within ±1 mm. The accuracy of Root-ZX apex locator was 70% within ±0.5 mm and 97.5% within ±1 mm. There was no significant difference between the accuracy of the two EALs.

Conclusion

Both the NovApex and Root-ZX EALs are useful for measuring the WL with high accuracy.

Clinical significance

Given the importance of accurate WL determination in the success of endodontic treatments, the accuracy of different apex locators should be evaluated.

Microorganisms and their by-products play a critical role in pulp and periradicular pathosis. Therefore, one of the main purposes of root canal treatment is disinfection of the entire system of the canal. This aim may be obtained using mechanical preparation, chemical irrigation, and temporary medication of the canal. For this purpose, various irrigation solutions have been advocated. Common root canal irrigants, such as sodium hypochlorite, chlorhexidine, and a mixture of tetracycline, acid, and detergent have been extensively reviewed. The aim of this review was to address the less common newer root canal irrigation solutions, such as citric acid, maleic acid, electrochemically activated water, green tea, ozonated water, and SmearClear.
