CALIBRATION OF THE EDGES HIGH-BAND RECEIVER TO OBSERVE THE GLOBAL 21 cm SIGNATURE FROM THE EPOCH OF REIONIZATION
Authors: Monsalve Raul A. , Rogers Alan E. E. , Bowman Judd D. , Mozdzen Thomas J.
Published: January 2017

The EDGES High-Band experiment aims to detect the sky-average brightness temperature of the 21 cm signal from the epoch of reionization in the redshift range

. To probe this redshifted signal, EDGES High-Band conducts single-antenna measurements in the frequency range 90–190 MHz from the Murchison Radio-astronomy Observatory in Western Australia. In this paper, we describe the current strategy for calibration of the EDGES High-Band receiver and report calibration results for the instrument used in the 2015–2016 observational campaign. We propagate uncertainties in the receiver calibration measurements to the antenna temperature using a Monte Carlo approach. We define a performance objective of 1 mK residual rms after modeling foreground subtraction from a fiducial temperature spectrum using a five-term polynomial. Most of the calibration uncertainties yield residuals of 1 mK or less at

confidence. However, current uncertainties in the antenna and receiver reflection coefficients can lead to residuals of up to 20 mK even in low-foreground sky regions. These dominant residuals could be reduced by (1) improving the accuracy in reflection measurements, especially their phase, (2) improving the impedance match at the antenna-receiver interface, and (3) decreasing the changes with frequency of the antenna reflection phase.
FLUORINE IN THE SOLAR NEIGHBORHOOD: NO EVIDENCE FOR THE NEUTRINO PROCESS

Published: January 2017

Asymptotic giant branch (AGB) stars are known to produce “cosmic” fluorine, but it is uncertain whether these stars are the main producers of fluorine in the solar neighborhood or if any of the other proposed formation sites, Type II supernovae (SNe II) and/or Wolf-Rayet (W-R) stars, are more important. Recent articles have proposed both AGB stars and SNe II as the dominant sources of fluorine in the solar neighborhood. In this paper we set out to determine the fluorine abundance in a sample of 49 nearby, bright K giants for which we previously have determined the stellar parameters, as well as alpha abundances homogeneously from optical high-resolution spectra. The fluorine abundance is determined from a 2.3 μm HF molecular line observed with the spectrometer Phoenix. We compare the fluorine abundances with those of alpha-elements mainly produced in SNe II and find that fluorine and the alpha-elements do not evolve in lockstep, ruling out SNe II as the dominating producers of fluorine in the solar neighborhood. Furthermore, we find a secondary behavior of fluorine with respect to oxygen, which is another evidence against the SNe II playing a large role in the production of fluorine in the solar neighborhood. This secondary behavior of fluorine will put new constraints on stellar models of the other two suggested production sites: AGB stars and W-R stars.
A ROTATIONALLY POWERED MAGNETAR NEBULA AROUND SWIFT J1834.9–0846
Authors: Torres Diego F.
Published: January 2017

A wind nebula generating extended X-ray emission was recently detected surrounding Swift J1834.9–0846. This is the first magnetar for which such a wind nebula was found. Here, we investigate whether there is a plausible scenario where the pulsar wind nebula (PWN) can be sustained without the need of advocating for additional sources of energy other than rotational. We do this by using a detailed radiative and dynamical code that studies the evolution of the nebula and its particle population in time. We find that such a scenario indeed exists: Swift J1834.9–0846's nebula can be explained as being rotationally powered, as all other known PWNe are, if it is currently being compressed by the environment. The latter introduces several effects, the most important of which is the appearance of adiabatic heating, being increasingly dominant over the escape of particles as reverberation goes by. The need of reverberation naturally explains why this is the only magnetar nebula detected and provides estimates for Swift 1834.9–0846's age.

The first 1.1 mm continuum survey toward the Small Magellanic Cloud (SMC) was performed using the AzTEC instrument installed on the ASTE 10 m telescope. This survey covered 4.5 deg2 of the SMC with 1σ noise levels of 5–12 mJy beam−1, and 44 extended objects were identified. The 1.1 mm extended emission has good spatial correlation with Herschel 160 μm, indicating that the origin of the 1.1 mm extended emission is thermal emission from a cold dust component. We estimated physical properties using the 1.1 mm and filtered Herschel data (100, 160, 250, 350, and 500 μm). The 1.1 mm objects show dust temperatures of 17–45 K and gas masses of 4 × 103–3 × 105 M
⊙, assuming single-temperature thermal emission from the cold dust with an emissivity index, β, of 1.2 and a gas-to-dust ratio of 1000. These physical properties are very similar to those of giant molecular clouds (GMCs) in our galaxy and the Large Magellanic Cloud. The 1.1 mm objects also displayed good spatial correlation with the Spitzer 24 μm and CO emission, suggesting that the 1.1 mm objects trace the dense gas regions as sites of massive star formation. The dust temperature of the 1.1 mm objects also demonstrated good correlation with the 24 μm flux connected to massive star formation. This supports the hypothesis that the heating source of the cold dust is mainly local star-formation activity in the 1.1 mm objects. The classification of the 1.1 mm objects based on the existence of star-formation activity reveals the differences in the dust temperature, gas mass, and radius, which reflects the evolution sequence of GMCs.
HYDRODYNAMICAL SIMULATIONS OF COLLIDING JETS: MODELING 3C 75
Authors: Molnar S. M. , Schive H.-Y. , Birkinshaw M. , Chiueh T. , Musoke G. , Young A. J.
Published: January 2017

Radio observations suggest that 3C 75, located in the dumbbell shaped galaxy NGC 1128 at the center of Abell 400, hosts two colliding jets. Motivated by this source, we perform three-dimensional hydrodynamical simulations using a modified version of the GPU-accelerated Adaptive-MEsh-Refinement hydrodynamical parallel code (GAMER) to study colliding extragalactic jets. We find that colliding jets can be cast into two categories: (1) bouncing jets, in which case the jets bounce off each other keeping their identities, and (2) merging jets, when only one jet emerges from the collision. Under some conditions the interaction causes the jets to break up into oscillating filaments of opposite helicity, with consequences for their downstream stability. When one jet is significantly faster than the other and the impact parameter is small, the jets merge; the faster jet takes over the slower one. In the case of merging jets, the oscillations of the filaments, in projection, may show a feature that resembles a double helix, similar to the radio image of 3C 75. Thus we interpret the morphology of 3C 75 as a consequence of the collision of two jets with distinctly different speeds at a small impact parameter, with the faster jet breaking up into two oscillating filaments.

We present the light curves of the hydrogen-poor superluminous supernovae (SLSNe I) PTF 12dam and iPTF 13dcc, discovered by the (intermediate) Palomar Transient Factory. Both show excess emission at early times and a slowly declining light curve at late times. The early bump in PTF 12dam is very similar in duration (∼10 days) and brightness relative to the main peak (2–3 mag fainter) compared to that observed in other SLSNe I. In contrast, the long-duration (>30 days) early excess emission in iPTF 13dcc, whose brightness competes with that of the main peak, appears to be of a different nature. We construct bolometric light curves for both targets, and fit a variety of light-curve models to both the early bump and main peak in an attempt to understand the nature of these explosions. Even though the slope of the late-time decline in the light curves of both SLSNe is suggestively close to that expected from the radioactive decay of 56Ni and 56Co, the amount of nickel required to power the full light curves is too large considering the estimated ejecta mass. The magnetar model including an increasing escape fraction provides a reasonable description of the PTF 12dam observations. However, neither the basic nor the double-peaked magnetar model is capable of reproducing the light curve of iPTF 13dcc. A model combining a shock breakout in an extended envelope with late-time magnetar energy injection provides a reasonable fit to the iPTF 13dcc observations. Finally, we find that the light curves of both PTF 12dam and iPTF 13dcc can be adequately fit with the model involving interaction with the circumstellar medium.
WIND-DRIVEN ACCRETION IN TRANSITIONAL PROTOSTELLAR DISKS
Authors: Wang Lile , Goodman Jeremy J.
Published: January 2017

Transitional protostellar disks have inner cavities that are heavily depleted in dust and gas, yet most of them show signs of ongoing accretion, often at rates comparable to full disks. We show that recent constraints on the gas surface density in a few well-studied disk cavities suggest that the accretion speed is at least transsonic. We propose that this is the natural result of accretion driven by magnetized winds. Typical physical conditions of the gas inside these cavities are estimated for plausible X-ray and FUV radiation fields. The gas near the midplane is molecular and predominantly neutral, with a dimensionless ambipolar parameter in the right general range for wind solutions of the type developed by Königl, Wardle, and others. That is to say, the density of ions and electrons is sufficient for moderately good coupling to the magnetic field, but it is not so good that the magnetic flux needs to be dragged inward by the accreting neutrals.
CHROMOSPHERICALLY ACTIVE STARS IN THE RAVE SURVEY. II. YOUNG DWARFS IN THE SOLAR NEIGHBORHOOD

A large sample of over 38,000 chromospherically active candidate solar-like stars and cooler dwarfs from the RAVE survey is addressed in this paper. An improved activity identification with respect to the previous study was introduced to build a catalog of field stars in the solar neighborhood with an excess emission flux in the calcium infrared triplet wavelength region. The central result of this work is the calibration of the age–activity relation for main-sequence dwarfs in a range from a few

up to a few Gyr. It enabled an order of magnitude age estimation of the entire active sample. Almost 15,000 stars are shown to be younger than

and ∼2000 younger than

. The young age of the most active stars is confirmed by their position off the main sequence in the J − K versus

diagram showing strong ultraviolet excess, mid-infrared excess in the J − K versus

diagram, and very cool temperatures (

). They overlap with the reference pre-main-sequence RAVE stars often displaying X-ray emission. The activity level increasing with the color reveals their different nature from the solar-like stars and probably represents an underlying dynamo-generating magnetic fields in cool stars. Of the RAVE objects from DR5, 50% are found in the TGAS catalog and supplemented with accurate parallaxes and proper motions by Gaia. This makes the database of a large number of young stars in a combination with RAVE’s radial velocities directly useful as a tracer of the very recent large-scale star formation history in the solar neighborhood. The data are available online in the Vizier database.
SOLAR ACTIVE LONGITUDES FROM KODAIKANAL WHITE-LIGHT DIGITIZED DATA
Authors: Mandal Sudip , Chatterjee Subhamoy , Banerjee Dipankar
Published: January 2017

The study of solar active longitudes has generated great interest in recent years. In this work we have used a unique, continuous sunspot data series obtained from the Kodaikanal observatory and revisited the problem. An analysis of the data shows a persistent presence of active longitudes during the whole 90 years of data. We compared two well-studied analysis methods and presented their results. The separation between the two most active longitudes is found be roughly 180° for the majority of time. Additionally, we also find a comparatively weaker presence of separations at 90° and 270°. The migration pattern of these active longitudes as revealed by our data is found to be consistent with the solar differential rotation curve. We also study the periodicities in the active longitudes and found two dominant periods of ≈1.3 and ≈2.2 years. These periods, also found in other solar proxies, indicate their relation with the global solar dynamo mechanism.
Neural Network to Failure Classification in Robotic Systems

Published: January 2017

A robotic system is a reconfigurable element, and inits programming, an algorithm can be implemented in order todetect and classify failures. This is an important step to ensurethat errors in actions do not cause damage or bring risks.Considering this, a Neural Network Multi Layer Perceptron(MLP) was used, in order to classify a set of failures in robotactuators, present in a database. This purpose is to analyze ifrobotic failures could be classified by MLP. The raw data aredivided in a temporal progression manner and torque in x, y andz axes. In total, five MLP neural networks were implemented foreach type of failure classification, using two different topologies.The number of neurons in the hidden layer is in accord with thecriteria of Kolmogorov and Weka, being the latter the besttopology for such application. In comparison to an algorithm(SKIL) using the same set of data, the MLP obtained the bestperformance in any topology of classification, with hit rates in80 to 90%.
Prendre/apprendre la parole : l’oral à l’école primaire dans les textes officiels
Authors: Pégaz-Paquet Anne , Cadet Lucile
Published: January 2017

Cette contribution aborde chronologiquement la question de l’oral et la façon dont il s’est construit en tant qu’objet d’enseignement, au regard de son traitement dans les instructions et programmes officiels de l’école primaire, depuis 1945 à aujourd’hui. L’étude montre comment l’évolution de la définition que l’institution lui a donnée a été influencée par les autres disciplines des sciences sociales, et quelles préconisations ont été faites pour la prise en charge d’un enseignement de l’oral « pour apprendre, à apprendre, pour penser et communiquer », en fonction des besoins que l’évolution sociologique de ces dernières décennies a fait apparaitre pour l’école.

Les enjeux contemporains du droit français de la nationalité à la lumière de son histoire
Authors: Fulchiron Hugues
Published: January 2017

L’histoire du droit français de la nationalité est étroitement liée aux réalités politiques, économiques et sociales d’une époque. Mais elle est aussi guidée par une sorte de « mystique », celle d’une communauté nationale formée par le partage d’un certain nombre de principes et de valeurs. Bien que concurrencée aujourd’hui par d’autres liens d’appartenance, la nationalité reste un élément fondamental du « vivre ensemble ».

Parler, pour quoi faire ?
Authors: Levivier Marc
Published: January 2017

L’article se propose d’établir un rapide tour d’horizon sur la spécificité du langage chez l’homme : c’est la faculté de parler qui fait l’homme. L’auteur s’appuie sur les diverses définitions du parler humain chez Heidegger, Benveniste, Alain, pour découper en courtes analyses son propos : « On ne parle jamais tout seul », « Parler, pour quoi faire ? », « On ne cesse de parler », « Parler », « On parlerait pour communiquer ? »... Il conclut sur : « On se parle en fabulant des merveilles d’intelligence, créativité de plume que ne doit pas plomber le verdict de véracité. »

L’enfant sera convoqué pour être entendu
Authors: Martinez Anne-Marie
Published: January 2017

À partir d’une longue expérience pratique, l’auteure présente trois situations cliniques de jeunes confiés en accueil familial : l’une pour un adolescent en 1980 et deux pour des plus jeunes, enfant et préadolescent, qui se situent en 2015. Cette présentation à trente-cinq années de distance permet de mesurer l’ évolution de la prise en charge en tenant compte de la parole de l’enfant, mais aussi ses limites, quand la recherche de la vérité factuelle et le traitement judiciaire prennent le pas sur la prise en compte de la subjectivité de l’enfant et de son univers mental en construction. L’enfant, alors, comme le souligne l’auteure, court le risque « d’ être pris au mot », piégé par une logique qui va le dépasser et dont les professionnels ont bien du mal à le prémunir.

La parole de l’enfant placé, mise dans les guillemets des écrits professionnels
Authors: Chalubert Joël
Published: January 2017

L’auteur propose une réflexion sur le sens des guillemets entre lesquels le professionnel doit placer la parole d’un enfant, placé lui-même dans une autre famille, un autre lieu que le sien. Les guillemets permettent-ils la neutralité voulue par les institutions, garantissent-ils que la parole de l’enfant soit réellement bien entendue, comprise ? Le professionnel se protège-t-il en faisant ce que la loi lui commande d’écrire, à savoir l’usage de ces fameux guillemets ? L’auteur conclut à la nécessité absolue de s’inclure dans l’écrit, d’« y être » de sa subjectivité, même objectivée par l’écrit, au risque sinon de rédiger un pur papier administratif, souvent rare de signifiants.
Adultes et adolescents dans l’institution scolaire. Éléments pour une rencontre intersubjective
Authors: Vorgy Lise
Published: January 2017

En France, l’École de la République est le lieu de la construction et d’apprentissage d’une culture commune qui, historiquement au moins, ignore sciemment les ancrages culturels, géographiques, sociaux du sujet, élève ou enseignant. De ce fait, elle laisse peu de place aux individus pris dans leur singularité et peine à entendre leur parole. L’enjeu d’une réflexion sur la parole dans l’institution scolaire concerne les rencontres qu’elle permet, ou non, entre adolescents et adultes. Rencontres qui apparaissent comme autant d’occasions éducatives et pédagogiques indispensables, et comme des accroches nécessaires pour que les jeunes d’aujourd’hui se scolarisent durablement. Deux obstacles à l’existence de rencontres intersubjectives authentiques se dessinent : le premier se situe dans le contexte scolaire lui-même qui, traversé par des représentations multiples et pas toujours conciliables, paraît soumis à une tension forte entre des objectifs contradictoires. Le second se situe dans l’absence de clarification des ressorts de l’investissement professionnel des différents acteurs adultes, dans et autour de l’École.

Enhancement of Professional Development of Front-Line Nurse Preceptors in a Dedicated Education Unit
Authors: Jones Elizabeth A. , Simpson Vicki , Hendricks Susan M.
Published: January 2017

Background:

Dedicated education units (DEUs) have been well established throughout the country as a means of developing clinical skills in nursing students. In a DEU, maintaining an adequate number of well-prepared clinical nurse preceptors is essential for unit sustainability and effective student perception.

Method:

This study was a quasi-experimental design using self-reported survey data. A comparison analysis was conducted using the initial results of the Revised Professional Practice Environment (RPPE) survey (i.e., pre-participation and no orientation) after completion of an orientation program and participation as preceptor in a DEU.

Results:

Front-line nurses who participated as preceptors for one semester in a DEU demonstrated statistically significant improvement in two of the eight components of professional practice measured by the RPPE.

Conclusion:

This study lends support to the notion that preceptors do experience improvement in professional practice as a result of participation in a DEU.

La vida de María Bautista y de sus milagros, sus adversidades y su ascensión a los cielos
Authors: Vinatea Martina
Published: January 2017

Este artículo describe el manuscrito, fechado en 1664, que recoge la vida de la Venerable madre María Bautista del convento de las Comendadoras de Santiago de Toledo como una biografía o «vida» de monjas. Las «vidas» de monjas fueron obras escritas dentro del convento que, a la sazón, era el espacio privilegiado para la escritura femenina, y fueron concebidas como discursos edificantes. La biografía de María Bautista, parte crónica, parte discurso edificante, recoge la estructura básica de este tipo de discurso y al construir un relato ejemplificador, se erige un modelo de santidad cuya finalidad última es desarrollar el paradigma de la «esposa de Cristo».

La Celestina interroga el código teatral: Tragedia fantástica de la gitana Celestina (1978) de Alfonso Sastre
Authors: François Jéromine
Published: January 2017

El dramaturgo español Alfonso Sastre quería transformar el teatro de su época en una plataforma de crítica social. En este marco, elaboró en sus obras dramáticas una serie de estrategias de distanciamiento que desvelaban al espectador los engranajes de la representación para incitarlo a buscar el sentido de la construcción disecada ante sus ojos. En la Tragedia fantástica de la gitana Celestina, dichas estrategias se desarrollan a partir del texto clásico de Rojas. En este estudio, se analiza así en qué medida Sastre utiliza personajes y citas de La Celestina para generar técnicas metateatrales que atañen tanto a la identidad de los personajes como a las acotaciones o a los diálogos, y que provocan un proceso demise en abyme de la obra teatral.

Research on Machine Tool Spindle System with Embedded FBG Temperature Sensors
Authors: Dong Yanfang , Zhou Zude , Liu Mingyao
Published: January 2017

The spindle system is the core component of machine tool, And the spindle bearing temperature directly influences the size and direction of the spindle thermal error, as well as determines the machining surface quality. A complete spindle system including cutting force, bearing preload upload system, and precise description of bearing temperature field is beneficial to thermal error study and analysis of machining error. This paper set up a spindle system, which covers a preload upload system and a cutting force simulation system, and also a spindle bearing temperature measurement system. Besides, the bearing temperature fields were measured. Results show that optical fiber grating could be applied to the spindle bearing distribution temperature field measurement very well. It could play a certain role in promoting the development of intelligent spindle study.

Authors: Daradkeh Yousef Ibrahim , ALdhaifallah Mujahed , Namiot Dmitry
Published: January 2017

This paper is devoted to mobile cloud services in Smart City projects. As per mobile cloud computing paradigm, the data processing and storage are moved from the mobile device to a cloud. In the same time, Smart City services typically contain a set of applications with data sharing options. Most of the services in Smart Cities are actually mashups combined data from several sources. This means that access to all available data is vital to the services. And the mobile cloud is vital because the mobile terminals are one of the main sources for data gathering.  In our work, we discuss criteria for selecting mobile cloud services.
Arduino Based Physics and Engineering Remote Laboratory
Authors: Cvjetkovic Vladimir M , Stankovic Uros
Published: January 2017

The concept of remote laboratories exists for some time with increasing importance for contemporary education in various fields and at various levels. Advance of remote labs is based on technology development and conceptual improvements with possible mutual influences such as when new technologies can make new concepts possible. Arduino is a family of small inexpensive single board computers (SBC) based primarily on microcontrollers with added Linux platforms on some boards for improved processing and Internet accessibility. Various shields extend interaction functionality of Arduino boards with environment. A number of other brands with quite similar concepts exist, with Arduino as one of very well-known and widespread. Arduino based remote lab concept relies on “Arduino only” implementation which is possible for many not too demanding applications without usual desktop or similar PC platforms. Such concept has many implications like project cheap price, interconnecting of boards for more demanding tasks, small consumption, autonomy, small dimensions, low installation requirements, which is suitable for applications at remote locations and applications requiring mobility. Hybrid solutions including Arduino or similar boards and other more powerful computer platforms may be optimal for more demanding applications. Programming and application development for Arduino and similar boards are supported by large community of developers and users that provide various libraries, solution examples, forums covering various thematic and application aspects. This paper discusses and presents some hardware and software configurations with Arduino and compatible boards that are used for implementation of experiments in physics and technics. Although the considered remotely operated experiments are different in nature, quite similar hardware and software architectures are used.
L’addiction aux jeux de hasard et d’argent en ligne : quelles spécificités ?
Authors: Barrault Servane , Varescon Isabelle
Published: January 2017

Modalité de jeu particulière, le jeu sur Internet connaît un essor très important. Le jeu pathologique est un réel problème de santé publique, accentué par le développement du jeu en ligne. En effet, ces dernières années, les jeux d’argent sur Internet ont bénéficié des progrès technologiques et sont en constante augmentation. Les recherches actuelles montrent, par ailleurs, que le jeu sur Internet comporte des caractéristiques structurelles et situationnelles jouant un rôle notable dans l’exacerbation de pratiques de jeu excessives.L’objectif de cette recherche est d’étudier les points communs et les différences entre jeux de hasard et d’argent en ligne et hors ligne. Nous avons comparé des joueurs de poker réguliers en ligne et hors ligne (n=245) en termes de profil sociodémographique et de pratique de jeu. Nos résultats permettent d’identifier des spécificités propres à la pratique de jeux des joueurs de poker en ligne et hors ligne, mais également des points communs entre ces deux groupes, notamment en termes de profil sociodémographique. Ceux-ci ouvrent des perspectives de recherche et des questionnements cliniques.
Us ou abus… pour le sociologue, la réalité sociale est grise. Entretien avec Rémy Rieffel
Authors: Rivron Vassili , Dolbeau-Bandin Cécile
Published: January 2017

Rémy Rieffel est professeur en Sciences de l’information et de la communication à l’université Paris 2 Panthéon-Assas et sociologue des médias. Il est directeur du Centre d’analyse et de recherche interdisciplinaire sur les médias (Carism) et enseignant à l’Institut français de presse (IFP) de l’université Paris II. En s’appuyant sur une enquête menée entre 2009 et 2012, Rémy Rieffel nous présente l’évolution des modalités d’accès aux médias d’information d’actualité. L’approche statistique et qualitative ne semble pas indiquer d’évolution brutale dans l’accès à l’information d’actualité, du moins si l’on considère les paramètres sociodémographiques classiques.

La science en action ? Luttes d’expansion institutionnelle à l’exemple de la nanomédecine en Allemagne
Authors: Papilloud Christian
Published: January 2017

Où la nanomédecine se développe-t-elle en Allemagne et quelles sont les institutions de la recherche scientifique allemande qui travaillent dans ce domaine ? Internet répond à cette question. On y trouve une documentation riche et des données accessibles au public, répondant de la philosophie de l’Open Data. Elles sont mises en ligne par deux acteurs incontournables de la nanomédecine, dont le premier est le ministère allemand de l’Éducation et de la Recherche (BMBF). Il fournit une nanomap qui localise l’activité de recherche dans les différents domaines des nanotechnologies et leurs acteurs en Allemagne. Le second est la European Technological Platform Nanomedicine (ETPN), qui publie sur Internet une carte européenne de la nanomédecine et fournit de la documentation sur la nanomédecine en Europe que l’on peut librement consulter sur le site Internet d’ETPN. Dans cet article, nous comparons ces données et nous montrons qu’elles ne se recoupent pas. Elles créent plutôt un effet loupe destiné à promouvoir ce que soit le BMBF, soit ETPN considèrent comme la recherche scientifique dans la nanomédecine en Allemagne. Nous faisons l’hypothèse que cet effet loupe est un indicateur des luttes d’expansion entre le BMBF et ETPN dont l’enjeu pour les deux institutions est la mainmise sur la régulation de la nanomédecine allemande. Cela les conduit à mettre en place des mesures de contrôle variées dont l’une d’entre elles, à laquelle nous nous attachons dans cet article, se présente sous la forme d’indicateurs qualitatifs de la nanomédecine. La définition et la construction de ces indicateurs sont à la base d’un projet de réorganisation de la nanomédecine allemande, une réorganisation dont nous mettons en évidence la signification selon que l’on se place du point de vue du BMBF ou d’ETPN.
Financial Innovation in Medium-Sized Enterprises Optimizes Their Gravitation Towards Capital Markets
Authors: Vemić Milan B.
Published: January 2017

A major problem for medium enterprises is ensuring that their financial management exercises prudence in the attraction of alternative sources of financing in transition into middle tier, larger enterprise status and towards stock exchange. Difficulties in attracting capital, the high cost of bank credit, absence of robust financial and business information reporting capacities may represent obstacles. One partial solution is capacity development for access to stock exchanges and having these institutions with a strong allocation capacity to efficiently finance these businesses. Though underdeveloped in transition economies, they are potentially important institutions in successful financial performance of businesses. In a review of conditions for handling risk and uncertainty, developing capacity for access to stock exchanges through working capital combinations, this treatise demonstrates that medium enterprises could benefit from this approach. Regulatory reforms to facilitate the use of stock exchange financing and well-designed financial management models are recommended.

Structural Change Management for Sustainable SME Development
Authors: Molnar Robert M.
Published: January 2017

This chapter addresses several approaches in investigation of the SME life cycles, particularly in respect to the structure, functions and behavior of these businesses. Once SMEs have been established they start to change both their structure and behavior. In fact, it could be stated that SMEs operate in a permanently changing environment. There are a lot of factors which influence these changes and optimizing their management is a great challenge for most SMEs. As a result of these factors and suboptimal SME management practices survival rate of new established SMEs is low. For researchers and practitioners it is therefore crucial to discover how to increase long-term survival chances of SMEs through relevant structural change. In order to contribute to this goal the chapter will consider the conceptual and research framework of the structure and practical management behavior of SMEs in change management processes. The chapter also provides suggestions on how to use practical management tools such as the PEST, SWOT and TOWS matrices and ways of their analysis.
Intermediary and Intermediation
Authors: Saglietto Laurence
Published: January 2017

The concept of intermediation has existed for a long time and taken numerous different forms. In this introductory chapter, we will therefore start by examining the state of the art of intermediaries through a range of different disciplines (history, management, economics, health, sociology), highlighting their historical evolution and current forms. We will then present the different models and theories of intermediation and their development, to produce an appreciation of their similarities and differences and a comprehensive view of the subject. This will allow us, in the last section, to propose the framework for a general theory of intermediation, in terms of organisational architecture and the services provided.
A Framework for Thinking Intermediation in Logistics Management
Authors: Quillaud Alban
Published: January 2017

The purpose of this chapter is to provide a logistics market structural grid that is not based on industry practices. Rather, it is based on clear principles of microeconomics. The analysis of the logistics market based on intermediation standards highlights the essential role of the logistics management function, and derives the key determinants of the logistics management outsourcing. It also provides elements that contribute to the understanding of future industry trends. This chapter logically identifies that the key principles of microeconomics are well applicable to the logistics. They even help better explain the emergence of the logistics management function. It demonstrates that those principles in the context of the new technologic edge could lead to a reintermediation, creating a restructuration of some segments of the market.
