La révolution des données est-elle en marche ?
Authors: Roca Thomas , Letouzé Emmanuel
Published: June 2017

« Bien informés, les hommes sont des citoyens ; mal informés, ils deviennent des sujets », écrivait Alfred Sauvy. Avec seulement 0,5 % de l’aide publique au développement (APD) affectée au soutien à la production de statistiques, la statistique officielle fait figure de parent pauvre de l’aide internationale. L’Afrique souffre en particulier d’un déficit de données socio-économiques et démographiques qualifié de « tragédie statistique » par certains experts. Les attentes et les possibilités sont grandes à l’ère de la dataification  – ou mise en données – de nos vies et de nos sociétés, fruit et facteur de la transition digitale.
Un séisme politique
Authors: Martin Pierre
Published: June 2017

La victoire d’Emmanuel Macron, candidat centriste libéral, face à Marine Le Pen, après un premier tour caractérisé par l’élimination de François Fillon et de Benoît Hamon, les candidats des deux forces politiques ayant gouverné la France depuis plus de trente ans, et la percée de la gauche radicale derrière Jean-Luc Mélenchon font de cette élection présidentielle un séisme politique. Ces résultats sont la conséquence de la profonde crise politique que traverse le pays. P. M.
Un nouveau clivage
Authors: Fourquet Jérôme
Published: June 2017

Présidentielle autrichienne, référendum sur le Brexit en Grande-Bretagne, présidentielle américaine, chacune de ces élections avait sa propre logique et s’inscrivait dans un contexte national particulier. Néanmoins, ces trois scrutins ont donné à voir la montée en puissance d’un clivage extrêmement puissant, celui opposant, pour faire court, les gagnants et les perdants de la mondialisation. Dans ces trois pays et ces trois scrutins, c’est cette ligne de fracture qui a structuré les votes bien davantage que la logique traditionnelle de l’affrontement gauche/droite. En France, l’opposition entre Marine Le Pen et Emmanuel Macron incarne et confirme ce nouveau clivage. J. F.
Poutine : un héros de conte russe
Authors: Erofeev Victor , Vergeade Christel
Published: June 2017

Victor Erofeev est un écrivain russe né en 1947. Il a grandi au cœur du pouvoir soviétique. Dans Ce bon Staline (Moscou, 2004), traduit en français en 2005 chez Albin Michel, il a raconté son « enfance stalinienne » et parisienne. Son père appartenait à la « cour de Staline », conseiller et interprète avant de devenir conseiller culturel à l’ambassade d’URSS à Paris de 1955 à 1958. L’annonce de sa « dissidence », racontée dans le puissant roman La Belle de Moscou (1990), brisa la carrière de son père. Il publia ensuite d’autres livres, dont La Vie avec un idiot (recueil de récits adapté en opéra en 1992), qui ont été traduits dans les principales langues occidentales, mais aussi en chinois, en japonais, en iranien, et qui font de lui un contemporain majeur. Il vit en Russie et a bien voulu nous confier ce portrait de Poutine. Nos lecteurs admireront la verve puissante et perspicace de cet écrivain. COMMENTAIRE
Trump : le Président d’une génération perdue
Authors: Sacco Giuseppe
Published: June 2017

Les valeurs fondatrices de l’Amérique, selon une récente et solennelle formulation, émise, paradoxalement, par une Chancelière allemande, seraient « le respect de la loi et de la dignité de chaque individu, indépendamment de son origine, de la couleur de sa peau, de sa religion, de son genre, de son orientation sexuelle ou de ses idées politiques ». Aucune mention n’est faite d’une garantie contre la discrimination pour l’âge. Et pourtant de là vient la tragédie dont a été victime une génération entière d’Américains, la génération qui est à l’origine du succès de Donald Trump, et de l’énorme secousse que l’Amérique vient de donner à la globalisation, et au système mondial dont les États-Unis ont, jusqu’ici, été le centre et le moteur.

Les souffrances sociales
Authors: Seibel Claude
Published: June 2017

Les milieux populaires sont confrontés depuis une quarantaine d’années à de graves difficultés. S’agit-il d’un abandon qu’ils ressentiraient ou du choc en retour d’un chômage qui, de longue date, frappe ces populations ? Cette thèse mériterait d’être analysée, région par région, pour mieux comprendre leur évolution économique et, en particulier, les impacts d’un marché mondialisé et d’un progrès technique important, parmi d’autres causes, sur la désindustrialisation qu’elles ont subie. Cette analyse détaillée n’est pas à notre portée, mais il est possible de dessiner à grands traits des domaines où les politiques publiques n’ont pas répondu aux attentes des milieux populaires depuis plusieurs décennies déjà. On se centrera sur une partie d’entre eux, en privilégiant les thèmes « Éducation-formation-emploi » et en suggérant des évolutions à la portée des responsables politiques et des partenaires sociaux.

Les relations Turquie-UE face à la crise migratoire : quelles évolutions ?
Authors: Monceau Nicolas
Published: June 2017

Désireux d’enrôler le gouvernement turc dans sa guerre contre les populations migrantes, l’Union Européenne a relancé des négociations enlisées depuis dix ans. Mais les rapports de plus en plus tendus entre les deux partenaires ne laissent pas présager d’un rapprochement très poussé ni très pérenne.
L’urbanisation néolibérale et conservatrice au prisme de l’autoritarisme en Turquie
Authors: Erdi Lelandais Gulcin
Published: June 2017

Depuis maintenant deux décennies, l’urbanisation en Turquie s’inscrit dans une logique néolibérale où la « rationalisation » de l’utilisation de l’espace vise avant tout à la maximisation du profit foncier. Ce phénomène n’est évidemment pas propre à l’arrivée au pouvoir du Parti de la justice et du développement (AKP –  Adalet ve Kalkınma Partisi ) : il suit son cours depuis les années 1990. Cependant, il s’est intensifié et son caractère particulièrement agressif et autoritaire s’est renforcé sous le mandat de ce parti, notamment vis-à-vis des quartiers populaires et informels mais aussi vis-à-vis de certains espaces publics.
Le dicible et l’indicible : le patrimoine au service de la nation turque
Authors: Girard Muriel
Published: June 2017

La célébration renouvelée de l’héritage ottoman participe à plein de la construction du récit national turc. L’instrumentalisation du patrimoine, y compris parfois du patrimoine des minorités ethniques et religieuses autrefois complètement passé sous silence, est ainsi l’une des stratégies de l’AKP pour légitimer son pouvoir.
Nostalgie d’empire, société fracturée et État fragilisé. La Turquie à l’heure de l’AKP post-coup d’État
Authors: Deboulet Agnès
Published: June 2017

Hamit Bozarslan revient ici sur la manière dont l’AKP se revendique de la mission historique de la nation turque et ottomane, puissance régionale à la fois protectrice de l’islam et chargée d’amener la « modernité » (État centralisé fort, grands travaux...) à ses voisins. R. T. Erdoğan se pose comme la figure incarnée de cette mission, garant de la « turcité », de l’islam et de l’État.
Guerre, état d’urgence, droits culturels et linguistiques kurdes bafoués. Retour sur le pluralisme selon l’AKP
Authors: Scalbert-Yücel Clémence
Published: June 2017

Pour des raisons électoralistes, et dans le cadre des discussions sur une éventuelle intégration à l’Union européenne, l’AKP dirigé par Erdoğan a accentué, à son arrivée au pouvoir en 2002, la politique amorcée par l’État turc à partir des années 1980 vis-à-vis des minorités kurdes : « pacification » par l’autorisation contingentée de la langue kurde et répression des mouvements politiques. Soutenu surtout par les municipalités conquises par des partis kurdistes ou prokurdes à l’est et au sud-est du pays, un champ culturel kurde protéiforme (presse, édition, spectacle, cinéma, enseignement...) s’est ainsi développé durant une trentaine d’années. La radicalisation autoritaire du régime depuis 2015, avec la reprise de la guerre menée en territoires kurdes puis l’état d’urgence suite au coup d’État de juillet 2016, donne lieu à une reprise en main brutale et massive. Limogeages, arrestations, dissolutions, interdictions, fermetures... : l’avenir des institutions et réseaux culturels kurdes n’a jamais été aussi précaire. La résistance kurde passe aussi par la réinvention de ce champ d’expression culturelle.
Les événements de Gezi, ou le début de la « dérive autoritaire », vu des périphéries...
Authors: Pérouse Jean-François
Published: June 2017

La contestation très médiatisée autour du parc de Gezi en mai-juin 2013 est sans doute un point de référence dans l’historique des luttes en Turquie. Une trop grande attention portée à la mobilisation autour du parc central d’Istanbul a cependant quelque peu éclipsé d’autres aspects et d’autres acteur·e·s de la mobilisation protéiforme qui a émergé lors de cette période de contestation.
Race, Space, and a Right to the City in New Haven: A Four-Century View
Authors: Huyssen David
Published: June 2017

Cet article suggère qu’une alliance politique entre les syndicats et les résidents de la ville de New Haven (Connecticut), peut fournir un modèle utile pour une praxis Lefebvrienne organisationnelle concernant le droit à la ville et soutient qu’une telle modélisation exige d’abord une compréhension historique des origines spécifiques de cette alliance dans le développement économique et politique de New Haven. L’article présente ainsi une étude du développement de la ville au cours de son histoire, en rapportant l’organisation raciale de son espace urbain aux histoires nationales de la transformation et des conflits raciaux et capitalistes. Empruntant des concepts de la géographie urbaine critique de Neil Smith et de Mandi Jackson, il retrace l’antagonisme qui a émergé entre l’Université de Yale et des résidents de la ville au regard des politiques sur le travail et de la rénovation urbaine au xx e siècle. Enfin, à l’aide de la théorie politique critique de Nancy Fraser, il analyse l’opposition de l’alliance syndicats-communauté – définie par un programme d’organisation transraciale, interclasses, et inter-sexes – envers la poursuite par Yale d’un programme néolibéral de réaménagement urbain.
Contre la laïcité. Le pavoisement de Jeanne d’Arc dans le Paris de 1909
Authors: Ihl Olivier
Published: June 2017

La pratique du pavoisement n’a guère été interrogée au cœur de l’histoire des mobilisations politiques. Cet article qui porte sur la béatification de Jeanne d’Arc dans le Paris de 1909 l’aborde comme une acclamation visuelle, une forme alternative de mise en scène qui, sous prétexte de lever l’étendard du Peuple, permet aux milieux de la droite monarchiste et catholique de s’opposer à la loi de 1905 sur la séparation des Églises et de l’État. Disqualifier la définition nouvelle de l’espace public : tel était l’enjeu de cet appel au drapeau censé donner naissance à une fête nationale concurrente du 14 juillet. Il faut y voir une prétention à la visibilité publique dressée contre la République du Bloc des gauches et contre la confessionnalisation du catholicisme. Pour dégager les ressorts de cette manifestation, on questionne ici le modèle de représentation dont le pavoisement se revendique ( vox populi, vox dei ), puis les dispositifs d’encadrement et de mise en scène qui contribuent à fixer sa signification, enfin on mesure l’étendue de son emprise sociale et spatiale – une façon de savoir à quel degré cette représentation du peuple parisien peut incarner le thème d’une démocratie hostile à la laïcité et aux élections.
The effect of diet and exercise on plasma metabolite and hormone concentrations in horses measured before and after exercise
Authors: Jensen R.B. , Blache D. , Knudsen K.E. Bach , Austbø D. , Tauson A.-H.
Published: June 2017

Exercise influences different endocrine and metabolic parameters, and information in the literature is sparse for some of these hormones and metabolites in the exercising horse. The aim of the present experiment was to study the metabolic response to exercise when feeding diets with varying carbohydrate composition (fibre and starch) under experimental conditions where diet and exercise were standardised and controlled. The response was investigated in a 4×4 Latin square design experiment using four Norwegian Coldblooded trotter horses. The dietary treatments were two fibre based diets, hay only and hay (85% of dry matter intake (DMI)) supplemented with molassed sugar beet pulp (mSBP) (15% of DMI), or two starch based diets of hay (68% of DMI) and barley (32% of DMI), and hay (68% of DMI), barley (26% of DMI) and mSBP (6% of DMI). Each diet was fed for 28 days; 16 days of adaptation followed by 12 days of data collection. 4 h after the morning feeding at 06:00 the horses performed a standardised exercise test (SET) lasting 45 min. Blood samples were taken before feeding the morning meal at 06:00, before the SET (10:00), after the SET (10:45) and after recovery from exercise (15:00), and plasma samples were analysed for relevant metabolites and hormones. Plasma leptin concentrations increased after exercise but were not affected by diet, whereas diet and exercise had no effect on the plasma concentrations of ghrelin and insulin like growth factor 1 (IGF-1). Furthermore, diet influenced the plasma concentrations of short-chained fatty acids (SCFA) more than exercise. The results provide important comparative information that can be useful in studies where diet and exercise cannot be controlled, e.g. in field studies.
Skills and Competencies Required for Jobs in Business Analytics
Authors: Leon Linda A. , Seal Kala Chand , Przasnyski Zbigniew H. , Wiedenman Ian
Published: June 2017

The explosive growth of business analytics has created a high demand for individuals who can help organizations gain competitive advantage by extracting business knowledge from data. What types of jobs satisfy this demand and what types of skills should individuals possess to satisfy this huge and growing demand? The authors perform a content analysis of 958 job advertisements posted during 2014-2015 for four types of positions: business analyst, data analyst, data scientist, and data analytics manager. They use a text mining approach to identify the skills needed for these job types and identify six distinct broad competencies. They also identify the competencies unique to a particular type of job and those common to all job types. Their job type categorization provides a framework that organizations can use to inventory their existing workforce competencies in order to identify critical future human resources. It can also guide individual professionals with their career planning as well as academic institutions in assessing and advancing their business analytics curricula.
Political Sentiment Mining
Authors: Bele Nishikant , Panigrahi Prabin Kumar , Srivastava Shashi Kant
Published: June 2017

Investigations on sentiment mining are mostly ensued in the English language. Due to the characteristics of the Indian languages tools and techniques used for sentiment mining in the English language cannot be applied directly to text in Hindi languages. The objective of this paper is to extract the political sentiment at the document-level from Hindi blogs. The authors could not find any literature about extracting sentiments at the document-level from Hindi blogs. They extracted opinion about one of India's very famous leaders who was a prominent face in the national election of 2014. They prepared the datasets from Hindi blogs reviews. They purposed the lexicon and machine learning technique to classify the sentiment. Their purposed method used four steps: (1) Crawling and preprocessing the blog reviews; (2) Extracting reviews relevant to the query using the Vector Space Model (VSM); (3) Identifying sentiment at the document level using the Lexicon method, and (4) Measuring the result using the Machine learning technique. Their experimental result demonstrates the effectiveness of our algorithms.
A Bio Inspired Approach for Cardiotocogram Data Classification
Authors: Menad Hanane , Amine Abdelmalek
Published: June 2017

In health care industry, data mining plays a significant task for predicting diseases. Numeral number of tests must be requisite from the patient for detecting a disease. However, using data mining technique can reduce the number of test that are required. Cardiotocogram data are data used for survey of baby statement for pregnant women by recording baby's fetal heartbeats, and uterine contractions for women. This work proposes a supervised approach based on artificial bee colony to predict type of fetal statement of Cardiotocogram data using previous recorded data, which was proposed the first time by the authors in (Rahmani, 2016). This paper is a continuation of that work in order to validate the approach as meta-heuristic. The obtained results were very good and satisfactory.

From Android Bug Reports to Android Bug Handling Process
Authors: Yu Liguo
Published: June 2017

Android is an operating system for mobile devices. Its development is led by Google and some other companies. Because of the open-source property of Android, anyone can report a bug through its online bug tracking system. In this paper, we analyze the bug reports of Android operating systems. Specifically, through this study, we would like to answer the following questions regarding Android development and its project management: (1) Could Android bug reports be handled on time? (2) What is the distribution of different maintenance activities initiated by Android bug reports? (3) How long does it take to handle an Android bug report? (4) Are the number of followers and the number of following messages of an Android bug report related to the effort spent on handling this bug report? Through answering these questions, this paper presents a comprehensive study of Android bug reporting and handling process. The information and knowledge obtained through this case study could help us better understand open-source software project, such as its development process and project management.
An Agent-Oriented, Workflow-Based Mobile Framework for Implementing Interoperable Healthcare Information Systems
Authors: Koufi Vassiliki , Malamateniou Flora , Vassilacopoulos George
Published: June 2017

Healthcare is an increasingly collaborative enterprise involving many individuals and organizations that coordinate their efforts toward promoting quality and efficient delivery of healthcare. To these ends, today, more than any other point in time, increased reliance is being placed on interoperability among healthcare information systems (HIS) which have been developed as monolithic, stand-alone systems without significant interfaces between them. Enabling heterogeneous HIS to interact within a Service-oriented architecture (SOA), such as a Web Services architecture, can help healthcare organizations to consistently deliver sustainable business value, with increased agility and cost effectiveness, in line with changing business needs. However, in the context of a SOA approach, issues of semantic interoperability still remain unresolved while new challenges arise regarding web service interoperability. This paper presents a mediation framework which provides a uniform interface to the underlying HIS and is accessible via Android-enabled devices. The proposed framework is based on the agent paradigm for both healthcare process management and management of interactions among the participating systems. The healthcare processes and all interactions involved in each process are described according to the workflow metaphor.
Non-Linear Properties of the VIX Index
Authors: Magafas L. , Hanias M. , Tavlatou A. , Kostantaki P.
Published: June 2017

This paper applies non-linear methods to analyze and predict the daily VIX index which is one of the most important stock indexes in the world. The aim of the analysis is to quantitatively show if the corresponding time series is a deterministic chaotic one and if one or more days ahead prediction can be achieved. The research employs Grassberger and Procaccia's methodology in the time series analysis in order to estimate the correlation and minimum embedding dimensions of the corresponding strange attractor. To achieve from the sample a multistep ahead prediction, the article gives the average for overall neighbours' projections of k-steps into the future. These results make the present work a valuable tool for traders, investors, and funds.
The Role of Trust in the Acceptance of Government Cloud
Authors: Alrashed Maha A. , Alotaibi Mutlaq B
Published: June 2017

This study proposes and empirically examines a revised and extended Unified Theory of Acceptance and Use of Technology (UTAUT) model, while acknowledging the role of trust on government cloud (G-Cloud) acceptance. The study utilized a quantitative research approach to examine the research model with data collected from a survey administered to IT professionals at government agencies in Saudi Arabia. The model was tested using the partial least squares structural equation modeling (PLS-SEM). Results show that trust is a major predictor of behavioral intentions to use G-Cloud that reduces uncertainty associated with the cloud and mitigates risk perceptions on the one hand, and significantly increases the perceptions of usefulness on the other hand. Furthermore, results indicate that performance expectancy, social influence, and facilitating conditions are all significant determinants of G-Cloud acceptance. Based on the findings, the study highlights several implications for practice and suggests opportunities for future research in the field of government cloud.
Comparative Study of the Influence of Requirements Analysis and User Participation on the Success of Two Software
Authors: Kamdjoug Jean Robert Kala , Ntede Cecile Angela Messina , Wamba Samuel Fosso , Dongmo Colette Eméline , Fobang Aime Noutsa
Published: June 2017

The requirements analysis is identified as the first step of a software project, a reality that is being neglected within Cameroonian companies. This study was carried out in the Centre Pasteur of Yaounde, Cameroon. It aims to compare the influence of both user participation (NPU) and requirements analysis (NABE) on the success of two software applications (custom one–core business vs. generic one–support activity). A survey using a structured questionnaire was administered to 73 users. The findings enabled us to identify NPU and NABE as salient factors for the use of the system. Indeed, NPU has a direct, positive impact on Use for core business software and an indirect impact for support software. Moreover, users are willing to use the system when involved. Further broad-based research would give a generalization of our findings in various contexts. Managers should rely on the importance of user involvement and the need for a well-conducted requirements analysis, for projects' success.
Privacy Protection for Data-Driven Smart Manufacturing Systems
Authors: Wong Kok-Seng , Kim Myung Ho
Published: June 2017

The Industrial Internet of Things (IIoT) is a new industrial ecosystem that combines intelligent and autonomous machines, advanced predictive analytics, and machine-human collaboration to improve productivity, efficiency and reliability. The integration of industry and IoT creates various attack surfaces and new opportunities for data breaches. In the IIoT context, it will often be the case that data is considered sensitive. This is because data will encapsulate various aspects of industrial operation, including highly sensitive information about products, business strategies, and companies. The transition to more open network architectures and data sharing of IoT poses challenges in manufacturing and industrial markets. The loss of sensitive information can lead to significant business loss and cause reputational damage. In this paper, the authors discuss emerging issues that are related to IIoT data sharing, investigate possible technological solutions to hide sensitive information and discuss some privacy management techniques in smart manufacturing systems.
Evaluation of the Ontological Completeness and Clarity of Object-Oriented Conceptual Modelling Grammars
Authors: Tilakaratna Prabodha , Rajapakse Jayantha
Published: June 2017

Several research studies have concluded that modelling grammars that support the Object-Oriented (OO) methodology focus more on modelling system design and implementation phenomena than real-world phenomena in IS users' domains. Thus, the purpose of this research study was to evaluate the suitability of OO modelling grammars for conceptual modelling. Although the research work focused on one widely used OO modelling grammar—namely, the Unified Modelling Language (UML)—the approach developed can be applied to any OO modelling grammar. The first phase of this research study focused on evaluating all UML constructs and identifying a subset of UML constructs that are capable of representing real-world phenomena in user domains. The second phase was an empirical evaluation of the identified subset of UML constructs. The results of this empirical evaluation suggest that instead of using all UML constructs the subset of UML constructs is better suited for conceptual modelling.
Effects of Domain Familiarity on Conceptual Modeling Performance
Authors: Suh Jihae , Park Jinsoo
Published: June 2017

Conceptual modeling is currently considered a significant phase in information systems development. Several modeling grammars and methods have been studied extensively in the information systems discipline. However, previous research on conceptual models has focused on certain grammar (syntax) or discovering a way to deliver the meaning of a model (semantic) more clearly and completely. With regard to the construct overload issue in conceptual modeling, past studies have had some deficiencies in research methods and even presented contradicting results. The objective of the present study is twofold. First, the authors researched the interaction effect among syntax, semantics, and pragmatics to discover the preferred design, context, and user knowledge with which models are more likely to be understood or interpreted. Second, they performed an experiment to reconcile conflicting outcomes and acquire a more complete and accurate understanding of construct overload. Specifically, the authors focused on understanding the end users' modeling performance between ontologically clear and unclear models. They applied an improved experimental methodology that integrates three features (i.e., syntax, semantic, pragmatic) rather than treat them individually and employs different degrees of domain familiarity in the conceptual model (i.e., familiar domain vs. unfamiliar domain). The result of this study will broaden the perspective on usability in the context of the conceptual model and may serve as a modeler's ontological guidance in terms of whether or not to contain construct overload when they create a model. In addition, this study makes the theoretical contribution by verifying the domain extensibility towards the theory of ontological clarity.
ADAM10-Interacting Tetraspanins Tspan5 and Tspan17 Regulate VE-Cadherin Expression and Promote T Lymphocyte Transmigration
Authors: Reyat Jasmeet S. , Chimen Myriam , Noy Peter J. , Szyroka Justyna , Rainger G. Ed , Tomlinson Michael G.
Published: June 2017

The recruitment of blood leukocytes across the endothelium to sites of tissue infection is central to inflammation, but also promotes chronic inflammatory diseases. A disintegrin and metalloproteinase 10 (ADAM10) is a ubiquitous transmembrane molecular scissor that is implicated in leukocyte transmigration by proteolytically cleaving its endothelial substrates. These include VE-cadherin, a homotypic adhesion molecule that regulates endothelial barrier function, and transmembrane chemokines CX3CL1 and CXCL16, which have receptors on leukocytes. However, a definitive role for endothelial ADAM10 in transmigration of freshly isolated primary leukocytes under flow has not been demonstrated, and the relative importance of distinct ADAM10 substrates is unknown. Emerging evidence suggests that ADAM10 can be regarded as six different molecular scissors with different substrate specificities, depending on which of six TspanC8 tetraspanins it is associated with, but TspanC8s remain unstudied in leukocyte transmigration. In the current study, ADAM10 knockdown on primary HUVECs was found to impair transmigration of freshly isolated human peripheral blood T lymphocytes, but not neutrophils or B lymphocytes, in an in vitro flow assay. This impairment was due to delayed transmigration rather than a complete block, and was overcome in the presence of neutrophils. Transmigration of purified lymphocytes was dependent on ADAM10 regulation of VE-cadherin, but not CX3CL1 and CXCL16. Tspan5 and Tspan17, the two most closely related TspanC8s by sequence, were the only TspanC8s that regulated VE-cadherin expression and were required for lymphocyte transmigration. Therefore endothelial Tspan5- and Tspan17-ADAM10 complexes may regulate inflammation by maintaining normal VE-cadherin expression and promoting T lymphocyte transmigration.
Enrichment of Human CCR6+ Regulatory T Cells with Superior Suppressive Activity in Oral Cancer

Published: June 2017

Human oral squamous cell carcinoma (OSCC) constitutes an inflammatory microenvironment enriched with chemokines such as CCL20, which promote cancer cell invasion and tumor progression. We found that in OSCC there is a correlation between the expression of CCL20 and FOXP3 mRNA. Therefore, we hypothesized that OSCC may favor the recruitment and retention of regulatory T (Treg) cells that express the CCL20 receptor, CCR6. Interestingly, most (∼60%) peripheral blood Treg cells express CCR6, and CCR6+ Treg cells exhibit an activated effector/memory phenotype. In contrast, a significant portion (>30%) of CCR6− Treg cells were found to be CD45RA+ naive Treg cells. Compared to CCR6− naive or memory Treg cells, CCR6+ Treg cells exhibit stronger suppressive activity and display higher FOXP3 expression along with lower methylation at the Treg-specific demethylated region of the FOXP3 gene. This predominance of CCR6+ Treg cells was also found in the draining lymph nodes and tumor-infiltrating lymphocytes of OSCC patients with early or late clinical staging. Moreover, CCR6+ Treg cells isolated from tumor-infiltrating lymphocytes or draining lymph nodes maintained similar phenotypic and suppressive characteristics ex vivo as did their counterparts isolated from peripheral blood. These results suggest that CCR6 marks activated effector or memory Treg phenotypes with superior suppressive activity in humans.
TCR Signal Strength Regulates Akt Substrate Specificity To Induce Alternate Murine Th and T Regulatory Cell Differentiation Programs
Authors: Hawse William F. , Boggess William C. , Morel Penelope A.
Published: June 2017

The Akt/mTOR pathway is a key driver of murine CD4+ T cell differentiation, and induction of regulatory T (Treg) cells results from low TCR signal strength and low Akt/mTOR signaling. However, strong TCR signals induce high Akt activity that promotes Th cell induction. Yet, it is unclear how Akt controls alternate T cell fate decisions. We find that the strength of the TCR signal results in differential Akt enzymatic activity. Surprisingly, the Akt substrate networks associated with T cell fate decisions are qualitatively different. Proteomic profiling of Akt signaling networks during Treg versus Th induction demonstrates that Akt differentially regulates RNA processing and splicing factors to drive T cell differentiation. Interestingly, heterogeneous nuclear ribonucleoprotein (hnRNP) L or hnRNP A1 are Akt substrates during Treg induction and have known roles in regulating the stability and splicing of key mRNAs that code for proteins in the canonical TCR signaling pathway, including CD3ζ and CD45. Functionally, inhibition of Akt enzymatic activity results in the dysregulation of splicing during T cell differentiation, and knockdown of hnRNP L or hnRNP A1 results in the lower induction of Treg cells. Together, this work suggests that a switch in substrate specificity coupled to the phosphorylation status of Akt may lead to alternative cell fates and demonstrates that proteins involved with alternative splicing are important factors in T cell fate decisions.
Effect of being conscious of others on moral condemnation
Authors: Oda Ryo
Published: June 2017

Moral condemnation may guide individuals into choosing the same side as other bystanders in disputes. If this is the case, people would condemn an actor more strongly when they are conscious of other bystanders than when they are not. In this study, participants were asked to judge the unacceptability of theft and deception in hypothetical situations. Unacceptability (condemnation) scores were compared between participants in two groups: those who provided only their scores and those who estimated others’ scores before providing their own. The results revealed that older participants were less willing to accept immoral behaviors than younger participants. When conscious of others’ judgments, younger participants tended to reduce their condemnation while older participants tended to increase their condemnation. Additionally, condemnation was stronger in females than males. The results support the hypothesis that those who are more likely to avoid direct and physical competition are more willing to condemn, and that moral condemnation functions as a “flag”.
Evidence on the stability of histone H1.a polymorphic variants during selection in quail
Authors: Kowalski Andrzej , Knaga Sebastian
Published: June 2017

Abstract. The goal of this work was to check whether selection for quantitative traits may cause a change in the histone H1 allelic complement and whether it can therefore be considered a modulator of histone H1-dependent chromatin functioning. For this purpose, a fluctuation of histone H1.a polymorphic variants was analyzed among a non-selected (control) quail line and the line selected for a high cholesterol content in the egg yolk. The histone H1.a was found to be polymorphic due to its differential migration rate in the AU-PAGE (acetic acid–urea polyacrylamide gel electrophoresis). Based on this, two H1.a isoforms (H1.a1 and H1.a2) that form three phenotypes (a1, a2 and a1a2) were distinguished in the quail lines tested. A comparably expressed (p > 0. 05) and low relative variable (coefficient of variation, CV  < 0. 25) histone H1.a phenotypes were in agreement with Hardy–Weinberg equilibrium (HWE) in both the non-selected (χ2 = 1. 29, p = 0. 25) and selected (χ2 = 1. 9, p = 0. 16) quail line. The similarity among quail lines was assessed based on the equal distribution of histone H1.a phenotypes (χ2 = 1. 63, p = 0. 44) and alleles (χ2 = 0. 018, p = 0. 89) frequency in both quail lines tested. This indicates that selection does not affect the histone H1.a polymorphic variants. The stability of histone H1.a during selection might suggest that likely chromatin processes coupled to the selected trait are not linked to the activity of histone H1.a.
Impact of pitch angle fluctuations on airborne lidar sensing ahead along the flight direction
Authors: Gurvich Alexander Sergeevich , Kulikov Victor Alexeevich
Published: June 2017

Abstract. Airborne lidar sensing ahead along the flight direction can serve for notification of clear air turbulence (CAT) and help to prevent injuries or fatal air accidents. The validation of this concept was presented in the framework of the DELICAT (DEmonstration of LIdar based CAT detection) project. However, the difficulties encountered during the processing of DELICAT data indicated the need of a better understanding the observational errors due to geometrical factors. In this paper, we discuss possible error sources imminent to this technique, related to fluctuations of the flight parameters, which may lead to an incorrect estimation of the turbulence intensity. We analyze the variations of backscattered lidar signal caused by fluctuations of the most important ahead sensing flight parameter, the pitch angle. The fluctuation values considered in the paper correspond to the error limits of the compensational gyro-platform used in the civil aviation. Uncompensated pitch angle fluctuations in the presence of aerosol concentration variations can lead to noticeable signal variations that can be mistakenly attributed to wind shear, turbulence or fast evolution of aerosol layer. We formulate the criteria that allow the recognition of signal variations caused by pitch angle fluctuations. Influence of these fluctuations is shown to be stronger for aerosol variations on smaller vertical scales. An example of DELICAT observations indicating a noticeable pitch angle fluctuation impact is presented.
Inclusion of tank configurations as a variable in the cost optimization of branched piped-water networks
Authors: Hooda Nikhil , Damani Om
Published: June 2017

Abstract. The classic problem of the capital cost optimization of branched piped networks consists of choosing pipe diameters for each pipe in the network from a discrete set of commercially available pipe diameters. Each pipe in the network can consist of multiple segments of differing diameters. Water networks also consist of intermediate tanks that act as buffers between incoming flow from the primary source and the outgoing flow to the demand nodes. The network from the primary source to the tanks is called the primary network, and the network from the tanks to the demand nodes is called the secondary network. During the design stage, the primary and secondary networks are optimized separately, with the tanks acting as demand nodes for the primary network. Typically the choice of tank locations, their elevations, and the set of demand nodes to be served by different tanks is manually made in an ad hoc fashion before any optimization is done. It is desirable therefore to include this tank configuration choice in the cost optimization process itself. In this work, we explain why the choice of tank configuration is important to the design of a network and describe an integer linear program model that integrates the tank configuration to the standard pipe diameter selection problem. In order to aid the designers of piped-water networks, the improved cost optimization formulation is incorporated into our existing network design system called JalTantra.
Composición del Fitoplancton en el embalse Los Laureles, Francisco Morazán, Honduras
Authors: Carranza Sánchez Jorge Luis , Hernández Oviedo Alba Isbela
Published: June 2017

El Embalse Los Laureles es un ecosistema artificial creado para abastecimiento de agua potable. Se estudiaron los parámetros físicos (temperatura, conductividad, turbidez y disco Secchi), químicos (pH, oxígeno disuelto,) y biológicos (clorofila a), con el objetivo de determinar la composición (abundancia y diversidad) del fitoplancton durante marzo-agosto 2014. Se obtuvieron muestras biológicas en tres puntos del embalse que comprenden cortina, centro y cola con 100 mL, utilizando red de arrastre a nivel sub superficial 20 – 30 cm de profundidad durante dos minutos para análisis cualitativo y con botella de Van Dorn a profundidad Secchi para análisis cuantitativo. Los perfiles clinógrados de oxígeno, turbidez elevada en el hipolimnion, baja transparencia de Secchi persistentes en todos los muestreos, 21 taxa identificadas, de las cuales 7 pertenecen a las Cianofíceas, 5 a las Bacillariophyceas y 9 a las Clorofíceas. Durante el tiempo de muestreo, las Cianofíceas se encontraron en un 67 %, las Bacillariophyceas en un 26% y Clorofíceas en un 7%, estos factores indican características de cuerpos de agua eutróficos. Sin embargo, para obtener resultados con mayor grado de confiabilidad, se recomienda realizar los muestreos físicos, químicos, biológicos y de productividad por lo menos cada quince días durante la época seca y lluviosa, aumentando los muestreos cuando se sospecha de floraciones algales, ya que estas relaciones son más precisas cuando los estudios se realizan por ciclos anuales, para identificar patrones de variación y tendencias que ayuden a prevenir y corregir este problema.Revista Portal de la Ciencia, No.11, diciembre 2016, p.90-104
Postponement Application in the Fast Fashion Supply Chain: A Review
Authors: Aftab MdAfzalul , Yuanjian Qin , Kabir Nadia
Published: June 2017

The successful implementation of push-pull supply chain management strategy has an important role in improving the competitiveness of an organization. The objective of a push-pull strategy is to minimize the holding of inventory level in finished form and rather produce finished goods from semi-finished inventory only upon receiving final order. One of the vital building blocks of push-pull supply chain strategy is postponement. The main objective of this review paper is to discuss the concept of postponement and its sub-categories such as product postponement and process postponement and their benefits. Then it is investigated how two prominent fast fashion retailers who are also categorized as original brand manufacturers in the apparel value chain apply the two variants of process postponement e.g. process standardization and process re-sequencing in their manufacturing operations to activate push pull supply chain strategy. The push-pull supply chain strategy in turn helps to reduce their order-to-delivery lead time to stores, reduce inventory holding level and minimize both physical costs and market mediation costs. The paper ends with concluding remarks. A framework is developed to illustrate the push-pull supply mechanism. This paper is a useful resource for practitioners in apparel supply chain willing to remove inefficiencies, costs and risks in their operations.

Modeling Effects of KM and HRM Processes to the Organizational Performance and Employee’s Job Satisfaction
Authors: Rahman Azizur , Hasan Najmul
Published: June 2017

There have been many literature focusing on Knowledge Management (KM) contribution to the business world, and there is still a lacuna of empirical studies related to KM and Human Resource Management (HRM) practices. This paper examines the effects of KM and HRM practices relating to the organizational performance and employee’s job satisfaction level. A theoretical model is proposed to identify significant relationships and to develop some hypothesis. These hypotheses are then tested with a structural equation modeling using a randomly selected survey data set of 150 respondents, where variables in the questionnaire have been considered from previous empirical studies. Results demonstrate significant positive effects of KM and HRM practices to the organizational performance. Finding also reveals that employee’s loyalty to the organization depends on employee’s job satisfaction which is highly influenced by the organizational performance. Although the sample is limited to a Bangladeshi organization, the new model can be employed to datasets from other developing countries.
