Viral Interference with Functions of the Cellular Receptor Tyrosine Phosphatase CD45
Authors: Thiel Nadine , Zischke Jasmin , Elbasani Endrit , Kay-Fedorov Penelope , Messerle Martin
Published: March 2015

The receptor tyrosine phosphatase CD45 is expressed on the surface of almost all cells of hematopoietic origin. CD45 functions are central to the development of T cells and determine the threshold at which T and B lymphocytes can become activated. Given this pivotal role of CD45 in the immune system, it is probably not surprising that viruses interfere with the activity of CD45 in lymphocytes to dampen the immune response and that they also utilize this molecule to accomplish their replication cycle. Here we report what is known about the interaction of viral proteins with CD45. Moreover, we debate putative interactions of viruses with CD45 in myeloid cells and the resulting consequences—subjects that remain to be investigated. Finally, we summarize the evidence that pathogens were the driving force for the evolution of CD45.

La maladie honteuse du psychologue à l’hôpital
Authors: Schwering Karl-Leo
Published: March 2015

À partir du récit de son expérience de psychologue clinicien en service de soins somatiques, l’auteur développe les enjeux psychiques à l’œuvre dans ce travail auprès de patients atteints de maladies graves. À côté de l’angoisse, c’est plus subtilement un vécu de honte autant que d’ennui qui déchire imperceptiblement son étoffe de professionnel. Vécus également éprouvés par les malades, prostrés dans l’univers étroit de la position hypocondriaque dans laquelle les confinent maladie et traitements. Selon l’auteur, s’aviser de l’importance et de la valeur de ces affects, représente pour le psychologue clinicien une dimension essentielle de son travail.

L’auteure conclut que le processus à l’œuvre dans le dispositif téléphonique s’apparente à celui d’un dispositif de type psychothérapeutique d’inspiration analytique en face-à-face, permettant ainsi de compléter l’éventail de l’offre de soins psychiques à disposition des patients.
Traumatisme et travail : un siècle après les névroses de guerre
Authors: Demaegdt Christophe
Published: March 2015

Les remaniements de la théorie traumatique opérés à la suite de la première guerre mondiale sont largement tributaires des problèmes cliniques posés par les « névroses de guerre ». L’auteur souligne que les controverses étiologiques portant sur cette entité clinique historiquement datée, et les conceptions traumatiques qui s’y réfèrent, n’accordent aucune place à l’expérience subjective du travail. À partir des connaissances spécifiques tirées de la psychopathologie du travail, cet article indique la fécondité et l’actualité de certaines questions métapsychologiques soulevées, mais résolument non soldées, par ces névroses de guerre. Il engage une discussion théorique sur les rapports entre travail, violence, et traumatisme, qui débouche sur la question suivante : Est-il possible de concevoir une théorie psychanalytique du traumatisme sans accorder une place conséquente à l’analyse du travail ?
La figure de Peter Pan ou le refus du corps vécu : de la clinique du vide dans la mélancolie
Authors: Wolf-Fédida Mareike , Lauer Camille
Published: March 2015

À partir de l’étude du mythe littéraire Peter Pan, mis en perspective avec la vie de son créateur, l’écrivain écossais James Matthew Barrie, les auteures se proposent, à travers un éclairage croisé psychanalytique et phénoménologique, de penser le concept du vide comme forme de mélancolie lorsque le clivage entre le corps et la pensée est poussé à l’extrême. Face à l’impossibilité de se placer comme exigence de travail pour la pensée, le corps pulsionnel emprisonne le sujet dans sa propre désertification psychique.

Intravitreal Anti-VEGF Therapy as a Treatment for Retinopathy of Prematurity: What We Know After 7 Years
Authors: Klufas Michael A. , Paul Chan R. V.
Published: March 2015

The authors review published clinical case reports, case series, and clinical trials evaluating the use of anti-vascular endothelial growth factor (VEGF) medications for the primary or adjunctive treatment of retinopathy of prematurity (ROP). A literature search of peer reviewed reports on PubMed was performed. More than 50 pertinent peer-reviewed publications between 2006 and 2014 were selected to be included in this review and are summarized in this report. There is a growing body of literature on the use of anti-VEGF therapy as a treatment for ROP, predominately in the form of case reports and small case series. Adverse effects from anti-VEGF treatment for ROP have been reported, but with limited follow-up time. The use of anti-VEGF as a treatment for ROP remains off-label.

Contextualized Text OLAP Based on Information Retrieval
Authors: Oukid Lamia , Benblidia Nadjia , Bentayeb Fadila , Asfari Ounas , Boussaid Omar
Published: March 2015

Current data warehousing and On-Line Analytical Processing (OLAP) systems are not yet particularly appropriate for textual data analysis. It is therefore crucial to develop a new data model and an OLAP system to provide the necessary analyses for textual data. To achieve this objective, this paper proposes a new approach based on information retrieval (IR) techniques. Moreover, several contextual factors may significantly affect the information relevant to a decision-maker. Thus, the paper proposes to consider contextual factors in an OLAP system to provide relevant results. It provides a generalized approach for Text OLAP analysis which consists of two parts: The first one is a context-based text cube model, denoted CXT-Cube. It is characterized by several contextual dimensions. Hence, during the OLAP analysis process, CXT-Cube exploits the contextual information in order to better consider the semantics of textual data. Besides, the work associates to CXT-Cube a new text analysis measure based on an OLAP-adapted vector space model and a relevance propagation technique. The second part is an OLAP aggregation operator called ORank (OLAP-Rank) which allows to aggregate textual data in an OLAP environment while considering relevant contextual factors. To consider the user context, this paper proposes a query expansion method based on a decision-maker profile. Based on IR metrics, it evaluates the proposed aggregation operator in different cases using several data analysis queries. The evaluation shows that the precision of the system is significantly better than that of a Text OLAP system based on classical IR. This is due to the consideration of the contextual factors.

Coupling Materialized View Selection to Multi Query Optimization
Authors: Boukorca Ahcene , Bellatreche Ladjel , Senouci Sid-Ahmed Benali , Faget Zoé
Published: March 2015

Materialized views are queries whose results are stored and maintained in order to facilitate access to data in their underlying base tables of extremely large databases. Selecting the best materialized views for a given query workload is a hard problem. Studies on view selection have considered sharing common sub expressions and other multi-query optimization techniques. Multi-Query Optimization is a well-studied domain in traditional and advanced databases. It aims at optimizing a workload of queries by finding and reusing common sub-expression between queries. Finding the best shared expression is known as a NP-hard problem. The shared expressions usually identified by graph structure have been used to be candidate for materialized views. This shows the strong interdependency between the problems of materialized view selection (PVS) and multi query optimization (PMQO), since the PVS uses the graph structure of the PMQO. Exploring the existing works on PVS considering the interaction between PVS and PMQO figures two main categories of studies: (i) those considering the PMQO as a black box where the output is the graph and (ii) those preparing the graph to guide the materialized view selection process. In this category, the graph generation is based on individual query plans, an approach that does not scale, especially with the explosion of Big Data applications requiring large number of complex queries with high interaction. To ensure a scalable solution, this work proposes a new technique to generate a global processing plan without using individual plans by borrowing techniques used in the electronic design automation (EDA) domain. This paper first presents a rich state of art regarding the PVS and a classification of the most important existing work. Secondly, an analogy between the MQO problem and the EDA domain, in which large circuits are manipulated, is established. Thirdly, it proposes to model the problem with hypergraphs which are massively used to design and test integrated circuits. Fourthly, it proposes a deterministic algorithm to select materialized views using the global processing plan. Finally, experiments are conducted to show the scalability of our approach.
Transforming Classrooms through Game-Based Learning
Authors: Vate-U-Lan Poonsri
Published: March 2015

This article reports an exploratory study which investigated attitudes towards the practice of game-based learning in teaching STEM (science, technology, engineering and mathematics) within a Thai educational context. This self-administered Internet-based survey yielded 169 responses from a snowball sampling technique. Three fifths of respondents were female (59.2% or N=100 females and 40.8% or N=69 males). Slightly more than half (55.6%) of the participants were elementary, secondary and university students. An additional second group of thirty-five per cent (N=59) were teachers who were in charge of STEM educational programs. Almost one tenth (9.5%, N=16) were parents. Frequency tables were used to analyze the quantitative data. The qualitative data was derived from a single open-ended question. The study found some divergent opinions that are useful in considering game-based learning for STEM education in Thailand. The overall average attitude towards the usage of game-based learning was very positive (3.92 out of 5, S.D. = 0.80). The study found that the majority of informants preferred that the delivery mode was online through a web browser followed by the mobile mode through an application and the least preferred was the offline mode recorded on CD-ROM (55.0%, 31.4% and 13.6% respectively). Thai was still the most preferred language to be used though both students and parents surveyed had a stronger preference for English and a Thai-English bilingual mode than the teachers. An important finding in this research was that stakeholders expected game-based learning to be integrated into the traditional classroom because of its enhanced learning approach.

Authors: Yuan Chao-Qun , Chua Fang-Fang
Published: March 2015

Web Service Composition is one of the technologies in Service Oriented Architecture which significantly increases the flexibility and reusability of developing service-oriented system. One of the major problems which occurs in web service composition is the difficulties of maintaining the existing running web service composition solutions due to the changes of business requirements, deployment environment, and other dynamic factors. In this proposed work, an automated system had been built to autonomously execute the web service composition. To achieve this objective, the authors had embedded semantic engine and Prolog in C# program to automatically and dynamically discover, compose and execute web service composition, i.e. a web service composition could be self-configured to automatically recover from execution failure and automatically re-generate composition solution due to business protocol changes.
Productivity Measurement in Software Engineering
Authors: Hernández-López Adrián , Colomo-Palacios Ricardo , Soto-Acosta Pedro , Lumberas Cristina Casado
Published: March 2015

Productivity measurement is constructed by the measure of tree categories of elements: inputs, outputs and factors. This concept, which started being used in the manufacturing industry, has been also a research topic within Software Engineering (SE). In this area, the most used inputs are time and effort and the most used outputs are source code and functionality. Despite of their known limitations, many of the most used productivity measures are still being used due to the information that they provide for management goals. In order to enable the construction of new productivity measures for SE practitioners, the existence of other inputs apart from time and effort, and other outputs, apart from source code and functionality is analyzed in this paper. Moreover, differences in usage of the inputs and production of the outputs among some SE job positions are analyzed and explained.
An Extensive Review of IT Service Design in Seven International ITSM Processes Frameworks
Authors: Mora Manuel , Gomez Jorge Marx , O'Connor Rory V. , Raisinghani Mahesh , Gelman Ovsei
Published: March 2015

The main international IT Service Management processes frameworks (ITIL v2, ISO/IEC 20000, COBIT 4.0, CMMI-SVC, MOF 4.0, and ITUP) include the design of IT services as part of their main best practices. However, despite having a common purpose and conceptual structure, they are organized differently. Hence, ITSM academic researchers and practitioners need to integrate a broad and diverse literature in relation to these frameworks. In Part I of this research, the authors pursued the goal of a descriptive-comparative analysis of fundamental concepts and IT service architecture design models used in the seven ITSM frameworks. In this paper (Part II) we complete this systemic analysis by using the ISO/IEC 15288 systems engineering standard and focusing on the IT design processes and practices reported in the aforementioned ITSM frameworks. Specifically, CMMI-SVC and ITUP are assessed in overall as the strongest frameworks from an engineering view, MOF 4.0 and ITIL v3 as moderate, and ISO/IEC 20000, ITIL v2 and COBIT as the weakest. ITSM academicians and in particular practitioners thus will need to distinguish their utilization according to the level of required detail of the IT service design process. This paper aims to advance our comprehension and understanding on the state of the art regarding what are IT services and how they can be designed. Thus it is of broad significance to ITSM researchers and practitioners.

Social Media as Resource for Involving Young People in Museum Innovation
Authors: Stuedahl Dagny , Lowe Sarah
Published: March 2015

This paper takes root in how social media represents a new framework and form of communication and how designing for the meditated encounters with these media require interdisciplinary perspectives from both cultural studies and interaction design. The authors argue that involving young people with social media as a participatory tool requires that designers take into consideration how visual interpretation, social semiotic, semantic and spatial practices are inherent in everyday social media usage. The authors report from a design research project where the media sharing software Instagram was used to explore how everyday users in an urban environment would relate to cultural heritage data. The authors propose a cultural studies based focus on the semiotics of mediation as a potential design based research methods that fit with participatory practices with social media.
An Exploratory Study on Policy Transfer for SIM Card Registration in Malawi
Authors: Makoza Frank
Published: March 2015

Majority of African countries have adopted policies for mandatory Subscriber Identifiable Module (SIM) card registration to mitigate security threats to citizens and society. However, there are few countries that have not yet adopted the mandatory SIM card registration policies. This study investigated the means through which SIM card registration policy may be transferred in countries without the policy. The context of Malawi was analysed which represented an ideal case of an African country without mandatory SIM card registration policy. The findings showed that the mandatory SIM card registration policy may be transferred through: (a) voluntary transfer to address local challenges related to mobile technologies (b) coercive transfer in response to meet international agreements. However, lack of national identification documents for mobile phone users and delays in implementing legal framework affected the transfer of the mandatory SIM Card registration in Malawi. It will be necessary to consider of social, economic and political factors when adopting the mandatory SIM card registration policy.

Study on the Mechanism of Magnetic Paraffin Control of Crude Oil Based on the Reorientation of Paraffin Crystals Induced by Magnetic Field
Authors: Zhang Wei Wei , Wang Dan Dan , Wang Ting Ting , Zhang San Chuan
Published: March 2015

The wax deposition during pipeline transportation impedes the flow of crude oil and eventually blocks the pipelines. Magnetic paraffin control (MPC) technology has been extensively adopted for its advantage in energy-saving and pollution reduction. In order to clarify the scientific essence of MPC problem, energy transition mechanism of paraffin control has been investigated based on the theory of molecular reorientation. Meanwhile, the mechanism of magnetic orientation of paraffin crystals was also studied in detail. Results show that diamagnetic anisotropy is the fundamental cause for which diamagnetic paraffin molecules can respond to magnetic field. Furthermore, magnetic-field-induced rotation of paraffin molecules could be remarkably enhanced by the ordered structure of paraffin molecules, such as liquid lamellar structures and paraffin crystallites, which could make it possible to overcome energy barrier and induce the orientation of paraffin molecules. In addition, the effect of magnetic orientation on the formation of paraffin crystal network was also investigated detailedly, and a novel MPC mechanism based on magnetic orientation of paraffin crystal was proposed. This research is of great significance to improve the paraffin control technology and its theoretical principle in our country.

Fish Swimming in MPF (Media and/or Paired Fin) mode has unique hydrodynamic characters and special application in resource exploration underwater. Inspired of the flexible shape and motion of undulating fin of “Nilotic Ghost” fish, a Hydraulic-driven Bionic Undulating Robot (HBUR) is developed and studied in the paper based on CFD method, to investigate the flexible characteristics of shape adaptation and hydrodynamics of HBUR fin, which has great significance for the propelling safety of HBUR underwater. In this paper, a mathematical model is brought forward to indicate the undulating motion of HBUR, which is formed by sequentially and periodically swing motions of Hydraulic Swing Actors (HSAs), and then the CFD method is introduced to calculate the hydro-forces when undulating shape of HBUR fin are distorted, because of distraction underwater. Results show that HBUR could produce propelling forces even when some of the HSAs are restricted from swinging, and shape adaptation ability of different part on HBUR fin is different, where the middle part is worse than the two sides. The propelling forces generated by undulating motion the rest of HBUR fin could be used to get the underwater robot out of trouble itself, and then undulating shape will restore to normal state.

Authors: Wei S.S. , Zeng Xiao Qing , Shen T. , Chen Y.J. , Wang W.Y.
Published: March 2015

In the railway operation, it's significant to obtain the distances between trains. A method based on RSSI for ranging and correction is proposed in this paper. The devices include a number of base stations installed along railways. The front train would send an active signal to the nearby base station N, when it transmits power signal to the following one. The following train also gives an active signal to its nearest base station 1 which would be enabled to gain signal from station N. The error of per meter of every section would be calculated by the known distance between base stations. The distances between trains could be corrected by the error and the loss of RSSI signal.
