Teaching English Grammar in Primary School
Authors: Sekelj Ana , Rigo Irene
Published: December 2018

This paper deals with English grammar and its position in the language teaching process. Grammar was for long taught for its own sake and this approach has done more harm than good because such knowledge of an algebraic kind of accuracy does not give learners the ability to communicate in real life situations. Fluency and accuracy are complementary and interdependent phenomena. Grammar does not work in isolation, but it should be used to preserve semantic relationships and to consider the discoursal factors. A new departure should be seen in which pedagogical grammar with consciousness raising will play an active role in the acquisition of the language. Teaching grammar at primary school begins with mechanistic drill exercises in the first phase and is gradually transformed into cognitive in the third phase. The teaching process should proceed in concentric circles spreading progressively the knowledge of the precedent phases.
"Veritas filia temporis" - Povijest, istina, jezik kao tehnološka konstrukcija
Authors: Šuran Fulvio
Published: December 2018

U uvodnom će se dijelu raspravljati o problematičnosti samog poimanja istine koja, zavisno o povijesnom razdoblju, doživljava određene suštinske promjene - tako je, na primjer, mitska istina bila shvaćena u vidu ritualne efikasnosti, koja se naknadno pod utjecajem retorike i sofistike pretočila u obliku uvjerljivosti (peitho’) kao učinkovitiji kriterij istinitosti od onog mitsko-ritualnog. Nakon uvodnog dijela uvidjet će se kako tek s filozofijom istina poprima današnji oblik logičke učinkovitosti i razumski apstraktne objektivnosti; oblik koji će naknadno dominirati čitavom zapadnom civilizacijom. Pojavom moderne znanosti, cjelina diskurzivnih osnova koju je utemeljila filozofija, postaje još krutija i određenija u svojoj specifičnosti. U suvremenom, postmodernističkom razdoblju pojavljuje se u svojoj sve izrazitijoj funkcionalnoj učinkovitosti: kao tehološki djelotvorna istina koja zamjenjuje dotrajalo tradicionalno poimanje istine u vidu mitološkog vjerovanja; kao manifestacija bitka ili predodžba ega/Jastva, započinjući tako nama poznat oblik znanja čija artikulacija ne ovisi o znanstvenim poljima, već prvenstveno o oruđu koje ju proizvodi. Danas, znanje sve više odgovara novoj logici konstrukcije i dekonstrukcije, gdje je moguće prisustvovati činjenici prema kojoj se promjenom mjesta mijenja i smisao oruđa, kao i činjenici prema kojoj je svako mjesto otvoreno neizvjesnostima jezičnih migracija i upisu u sve raznovrsnije igre. Istina se, dakle, vrednuje prema svojoj učinkovitosti, koja svoje pravo značenje nalazi u onome što je Nietzsche svojevremeno nazvao voljom za istinom. Radi se o htijenju koje se u potpunosti poklapa s čovjekovom voljom za znanjem, koja mu omogućava da se snađe u svijetu koji za njega nije bio izvorno određen.
Bilješke o jeziku Drugoga beramskog brevijara
Authors: Mihaljević Milan
Published: December 2018

Autor u članku iznosi zapažanja o jeziku 2. beramskoga brevijara (Ljubljana, NUK, Ms163) do kojih je došao transliterirajući 120 stranica iz njegove druge knjige. U tom se hrvatskoglagoljskom brevijaru koji se rabio u Bermu, kao i u većini drugih kodeksa, isprepliću elementi crkvenoslavenskoga jezika naslijeđeni iz predloška i elementi govornoga jezika koje su pisari, svjesno ili nesvjesno unosili u tekst koji su prepisivali. Istaknute su uočene zanimljivosti na grafijskoj, fonološkoj, morfološkoj, sintaktičkoj i leksičkoj razini te pogreške koje pružaju zanimljive podatke o pisarevu materinskom govoru kao i o njegovu poznavanju crkvenoslavenskoga jezika. Autor zaključuje da je brevijar pisan u središnjoj Istri (vjerojatno u samom Bermu), ali da je prepisan sa starijega glagoljskoga predloška koji potječe najvjerojatnije s Krka.

Authors: Agar Corbinos Lorenzo
Published: December 2018

Chile ha sido elegido como destino migratorio por diversos grupos humanos. Entre ellos, un importante número de inmigrantes árabes y judíos, cuyos descendientes forman hoy parte activa de la sociedad chilena. El aporte cultural de los inmigrantes y descendientes ha impactado positivamente en el desarrollo del país. Este artículo presenta una experiencia pionera de diálogo entre jóvenes descendientes que integran la comunidad árabe y judía en Chile. En el contexto de una sociedad cada vez más multicultural, se hace relevante revisar las interacciones entre grupos de distinto origen. El objetivo de esta iniciativa de diálogo entre jóvenes de ambas comunidades, ha sido generar una instancia comunicacional, como una primera experiencia en la formación de una sociedad más abierta, integradora y respetuosa de la diversidad. Ambas comunidades, más allá de sus diferencias, tienen historias de vida comunes que permiten dar ejemplos de convivencia y diálogo. Un punto esencial en la metodología ha sido la de reforzar la mirada cultural por sobre la ideológica. Estamos convencidos que dar a conocer y promover este tipo de experiencias, ayudará al reconocimiento de la necesidad del diálogo intercultural con miras a aumentar los grados de cohesión social y respeto por los derechos de todos los grupos humanos.

Published: December 2018

El presente texto nos aproxima a la compresión de experiencias y desafíos que viven los jóvenes desvinculados de diferentes grupos armados, luego de egresar de los programas de atención a víctimas, en su proceso de reintegración a la vida civil. A través de diversos encuentros, se propiciaron espacios de diálogos que permitieron conocer sus testimonios, con el objetivo de implementar estrategias pedagógicas para atender estas poblaciones, y ahondar en nuestra realidad nacional. El reclutamiento forzado de menores, es un fenómeno social de impacto internacional que ha motivado múltiples estudios en especial desde las ciencias sociales, este fenómeno se presenta con mayor frecuencia en zonas rurales marginadas por el Estado, dominadas por estados paralelos o repúblicas independientes, dedicadas a actividades ilícitas. Hemos visto la necesidad de promover la creación de redes de apoyo institucionales y comunitarias que fortalezcan dichos procesos de reinserción ante un eventual acuerdo de paz en Colombia.

La paz y la justicia en un posible escenario de posconflicto en el país, ha sido un tema ampliamente debatido por académicos y politólogos, sin embargo es necesario aproximarse a los discursos que las víctimas del conflicto armado construyen desde sus daños y esperanzas. El artículo reflexiona en torno a las expresiones que diez familias víctimas del desplazamiento forzado asentadas en Soacha, construyen desde su dramática experiencia en la guerra y sus precariedades socioeconómicas en el municipio. Sin duda todos anhelan la paz, pero con justicia reparativa. La reflexión es el resultado de la investigación realizada por la Universidad Colegio Mayor de Cundinamarca, programa de Trabajo Social, en 2014, que indagó las representaciones sociales que de su condición de víctimas estas familias construyen en el marco de la Ley 1448. Aquí la justicia y la paz, surgieron como categorías emergentes, el diseño fue de corte cualitativo.

Indonesia, a developing country, is still facing nutrition problems caused by lack of access to food and nutrition knowledge. Adolescents play an important role in a long term preventing of nutrition problem. Competition and award are ways of increasing adolescent interest and motivation in gaining nutrition knowledge. Therefore, the purpose of this empowerment program is to improve nutrition capacity og high school students (HSS) through a nutrition ambassador competition and award. The selection of nutrition ambassador candidates is carried out through written selection for 2nd grade HSS in 5 high schools (HS) in each selected city oN 8 cities of Indonesia. Five best couples from each HS then follow a second stage written selection at city level. Finally, the five best couple nominated from the second stage were then interviewed to determine the best three couple as nutrition ambassadors for every city. The result showed about 200 HSS involved as the candidates: and they read the balance nutrition guidebook from ministry of health as an online compulsory reading book which was uploaded in the web of PERGIZI PANGAN Indonesia. The mean nutrition knowledge score of the NA was 65.4 ± 12.9 which categorized as moderate level. This activity was appreciated by school principals and by local health district office heads. The nutrition ambassadors helped local health office to educate nutrition to HSS in each city. Now with the assistance from PERGIZI PANGAN Indonesia, they are sharing nutrition information and experience via WhatsApp Group. This implies that nutrition ambassador competition and award could be developed to improve nutrition capacity of HSS.

Published: December 2018

Preclinical and clinical studies have shown that prior receipt of radiotherapy enhances antitumor immune responses, a phenomenon we call the “radio-memory effect.” However, all of the evidence regarding this effect to date comes from work with PD1/PDL1 inhibitors. Here we explored whether this effect also occurs with other forms of immune therapy, specifically interleukin-2 (IL-2). We retrospectively assessed outcomes in patients with malignant pleural effusion (MPE) who had previously received radiotherapy for non-small-cell lung cancer (NSCLC) within 18 months before the intrapleural infusion of IL-2 or cisplatin. Radiotherapy sites included lungs, thoracic lymph nodes, and intracranial. All patients received intrapleural infusion of IL-2 or cisplatin, and most had had several cycles of standard chemotherapy for NSCLC. We identified 3,747 patients with MPE (median age 64 years [range 29–88)) treated at one of several institutions from August 2009 through February 2015; 642 patients had been treated with IL-2 and 1102 with cisplatin and had survived for at least 6 months afterward. Among those who received IL-2, 288 had no radiotherapy, 324 had extracranial (i.e., thoracic) radiotherapy, and 36 had intracranial radiotherapy. The median follow-up time for surviving patients was 38 months. Patients who had received extracranial radiotherapy followed by IL-2 had significantly longer PFS than patients who had not received extracranial radiotherapy (i.e., either no radiotherapy or intracranial radiotherapy). Patients who had received intracranial or extracranial radiotherapy followed by IL-2 had significantly longer OS than did other patients. No survival advantage was noted for prior radiotherapy among patients who received intrapleural cisplatin. We speculate that previous radiotherapy could enhance the efficacy of subsequent intrapleural infusion of IL-2, a “radio-memory” effect that could be beneficial in future studies.

Literature from different parts of the world reported that antibiotic abuse is evident in dental practice. One aspect of this abuse is prescribing antibiotics for non-indicated orofacial infections. The use of some herbal anti-edematous agents has been recommended for reducing post-operative swelling/edema in certain oral and maxillofacial surgical procedures. In this review we describe the possible benefits of using these agents for certain cases of facial cellulitis in order to reduce the number of antibiotic prescriptions for this particular clinical situation.
VIRTUAL AND FLYING MODELS FOR AIRCRAFT DEVELOPMENT

Published: December 2018

In the field of the widespread research activity focusing on ultra light aircraft, two different needs were merged into one single design activity: the educational necessity of getting students involved into a real design effort. Our intention was to apply the conceptual design methodologies developed by our research group, which is named ASSET (Aero Space Systems Engineering Team), to a real case study. The design case study was chosen after a thorough examination of existing vehicles. Starting from a reference aircraft, the concept of the new aircraft was then conceived and is now under completely defined. The conceptual design of the new ultra light aircraft is already finished, whereas its detailed design has just begun and is proceeding through the utilization of both virtual (3D‐CAD) and physical models.
USING GENERALIZED STOCHASTIC METHOD TO EVALUATE PROBABILITY OF CONFLICT IN CONTROLLED AIR TRAFFIC
Authors: Babak Vitaly , Kharchenko Volodymyr , Vasylyev Volodymyr
Published: December 2018

The introduction of the new concepts of air traffic management (ATM) and transition from centralized to decentralized air traffic control (ATC) with the change of traditional ATM to Cooperative ATM sets new tasks and opens new capabilities for air traffic safety systems. This paper is devoted to the problem of evaluating the probability of aircraft collision under the condition of Cooperative ATM, when the necessary information is available to the subjects involved in the decision‐making process. The generalized stochastic conflict probability evaluation method is developed. This method is based on the generalized conflict probability equation for evaluation of potential conflict probability and aircraft collision probability that is derived by taking into account stochastic nature and time correlation of deviation from planned flight trajectory in controlled air traffic. This equation is described as a multi‐dimensional parabolic partial differential equation using a differential (infinitesimal) operator of the multi‐dimensional stochastic process of relative aircraft movement. The common procedure for the prediction of conflict probability is given, and the practical application of the generalized method presented is shown. All equational coefficients of a differential operator for a practical solution of a parabolic partial differential equation are derived. For some conditions, the numerical solution of the conflict probability equation is obtained and illustrated graphically.
OPTIMIZATION OF SPAR MASS AND FUSELAGE LOCATION TO DECREASE LOSS OF AIRPLANE LIFT FORCE
Authors: Ohapkin Alexey , Serokhvostov Sergey
Published: December 2018

Considered in this paper is the problem of optimizing spar mass to minimize lift force loss for a set of spar cross‐section shapes in cases of constant and elliptical lift force distributions. The main idea is that the deformation of the spar under aerodynamic and gravitational forces causes a decrease in lift force and that there must be some optimal spar strength that gives a minimum for the sum of the loss of lift force and spar weight. The influence of fuselage location on the loss of lift force in the case of multi‐fuselage design is also investigated. The behaviour of lift loss as a function of the location of fuselages is discussed.
INFORMATICS TOOLS USING ESTIMATION DURING PILOT TRAINING
Authors: Gruszecki Jan , Zajdel Zbigniew , Rzucidło Pawel
Published: December 2018

The human interest in flight simulators and tools that facilitate the effective formation of piloting skills has more than half a century of tradition. Marked growth development of these tools happened after the implementation of digital techniques into the structure of simulators and after the obtainment of independent computer applications the enabling the operator's predispositions and performance level to be controlled and estimated. The questions that are posed in this area of such specific tools have been very often oriented towards the possibility and reasonableness of replacing real training flights with a simulation technique. Working on the problem of improving the level of safety in civil aviation, the authors conducted tests to determine the possibility of formalizing the principles of admittance for computers tools that are identified as OTD (Other Training Device) followed from JAR –STD 3A.005 (f) regulations. One of the aims of the experiments was to confirm the usefulness of the statistical methods that had been used to identify the pilot's skill level estimated for short series of flights. RUT Aviation Training Centre students, whose individual predispositions as operators and performance levels had been estimated using the WOMBAT – CS TOOL, took part in experiments based on elements of flight normalized in JAR – FCL 1.210. In this paper, the authors present and discuss the assumptions, accomplishments, and results of that experiment.
Thermophysical Modeling of Asteroid Surfaces Using Ellipsoid Shape Models
Authors: MacLennan Eric M. , Emery Joshua P.
Published: December 2018

Thermophysical Models (TPMs), which have proven to be a powerful tool in the interpretation of the infrared emission of asteroid surfaces, typically make use of shape models and spin axes obtained a priori for use as input boundary conditions. We test and then employ a TPM approach—under an assumption of an ellipsoidal shape—that exploits the combination of thermal multi-wavelength observations obtained at pre- and post-opposition. Thermal infrared data, when available at these observing circumstances, are inherently advantageous in constraining thermal inertia and sense of spin, among other physical traits. We show that, despite the lack of a priori knowledge mentioned above, the size, albedo, and thermal inertia of an object are well-constrained with precision comparable to that of previous techniques. Useful estimates of the surface roughness, shape, and spin direction can also be made, to varying degrees of success. Applying the method to Wide-Field infrared Survey Explorer observations, we present best-fit size, albedo, thermal inertia, surface roughness, shape elongation and sense of spin direction for 21 asteroids. We explore the thermal inertia’s correlation with asteroid diameter, after accounting for its dependence on the heliocentric distance.
Re-analyzing the Dynamical Stability of the HD 47366 Planetary System

Published: December 2018

Multi-planet systems around evolved stars are of interest to trace the evolution of planetary systems into the post-main-sequence phase. HD 47366, an evolved intermediate-mass star, hosts two giant planets on moderately eccentric orbits. Previous analysis of the planetary system has revealed that it is dynamically unstable on timescales much shorter than the stellar age unless the planets are trapped in mutual 2:1 mean-motion resonance, inconsistent with the orbital solution presented in Sato et al., or are moving on mutually retrograde orbits. Here we examine the orbital stability of the system presented in S16 using the n-body code Mercury over a broad range of a–e parameter space consistent with the observed radial velocities, assuming they are on co-planar orbits. Our analysis confirms that the system as proposed in S16 is not dynamically stable. We therefore undertake a thorough reanalysis of the available observational data for the HD 47366 system, through the Levenberg–Marquardt technique and confirmed by MCMC Bayesian methodology. Our reanalysis reveals an alternative, lower-eccentricity fit that is vastly preferred over the highly eccentric orbital solution obtained from the nominal best-fit presented in S16. The new, improved dynamical simulation solution reveals the reduced eccentricity of the planetary orbits, shifting the HD 47366 system into the edge of a broad stability region, increasing our confidence that the planets are all that they seem to be. Our rigorous examination of the dynamical stability of HD 47366 stands as a cautionary tale in finding the global best-fit model.
Low-latitude Aurorae during the Extreme Space Weather Events in 1859

Published: December 2018

The Carrington storm (1859 September 1/2) is one of the largest magnetic storms ever observed, and it caused global auroral displays in low-latitude areas, together with a series of multiple magnetic storms from 1859 August 28 to September 4. In this study, we revisit contemporary auroral observation records to extract information on their elevation angle, color, and direction to investigate this stormy interval in detail. We first examine the equatorward boundary of the “auroral emission with multiple colors” based on descriptions of elevation angle and color. We find that their locations were 36.°5 ILAT on August 28/29 and 32.°7 ILAT on September 1/2, suggesting that trapped electrons moved to, at least, L ∼ 1.55 and L ∼ 1.41, respectively. The equatorward boundary of “purely red emission” was likely located at 30.°8 ILAT on September 1/2. If the “purely red emission” was a stable auroral red arc, it would suggest that trapped protons moved to, at least, L ∼ 1.36. This reconstruction with observed auroral emission regions provides conservative estimations of magnetic storm intensities. We compare the auroral records with magnetic observations. We confirm that multiple magnetic storms occurred during this stormy interval, and that the equatorward expansion of the auroral oval is consistent with the timing of magnetic disturbances. It is possible that the August 28/29 interplanetary coronal mass ejections (ICMEs) cleared out the interplanetary medium, making the ICME for the Carrington storm on September 1/2 more geoeffective.

We present an analysis of the final data release of the Carnegie Supernova Project I, focusing on the absolute calibration of the luminosity–decline rate relation for Type Ia supernovae (SNe Ia) using new intrinsic color relations with respect to the color-stretch parameter, s

BV
, enabling improved dust extinction corrections. We investigate to what degree the so-called fast-declining SNe Ia can be used to determine accurate extragalactic distances. We estimate the intrinsic scatter in the luminosity–decline rate relation and find it ranges from ±0.13 mag to ±0.18 mag with no obvious dependence on wavelength. Using the Cepheid variable star data from the SH0ES project, the SN Ia distance scale is calibrated and the Hubble constant is estimated using our optical and near-infrared sample, and these results are compared to those determined exclusively from a near-infrared subsample. The systematic effect of the supernova’s host galaxy mass is investigated as a function of wavelength and is found to decrease toward redder wavelengths, suggesting this effect may be due to dust properties of the host. Using estimates of the dust extinction derived from optical and near-infrared wavelengths and applying these to the H band, we derive a Hubble constant

A survey observation of the DNC (J = 1−0 and J = 3−2) and HN13C (J = 1−0 and J = 3−2) emission toward 34 Class 0 and I protostellar sources in the Perseus molecular cloud has been conducted with the NRO 45 m and IRAM 30 m telescopes to explore how the deuterium ratio of the neutral species changes after the birth of a protostar. We have detected the J = 1−0 and J = 3−2 lines of DNC toward 32 sources and the J = 1−0 and J = 3−2 lines of HN13C toward 31 and 26 sources, respectively. A mean deuterium ratio of HNC, which is defined as R
D(HNC) = N(DNC)/N(HNC), is found to be 0.049–0.056. We compare R
D(HNC) with physical parameters of the sources, and find a negative correlation between R
D(HNC) and the bolometric temperature. This result suggests that R
D(HNC) decreases as a protostar evolves. Compared with the deuterium ratio of the molecular ion

, R
D(HNC) seems to decrease slowly with the protostellar evolution.
New Insights into the Galactic Chemical Evolution of Magnesium and Silicon Isotopes from Studies of Silicate Stardust
Authors: Hoppe Peter , Leitner Jan , Kodolányi János
Published: December 2018

We report high-resolution (<100 nm) Mg and Si isotope data of 12 presolar silicate grains (230–440 nm) from red giant and/or asymptotic giant branch stars that were previously identified based on their anomalous O-isotopic compositions (11 Group 1 grains and one Group 2 grain) in five primitive meteorites. The data were acquired by NanoSIMS ion imaging with the new Hyperion ion source that permits Mg and Si isotope measurements of presolar silicates with higher precision than was possible before. For a subset of five Group 1 (“category A”) grains, 25Mg/24Mg and 29Si/28Si ratios correlate with the inferred initial 18O/16O ratios of their parent stars, a measure of stellar metallicity. The Mg and Si isotope data of category A grains show positive correlations in the δ
25Mg–δ
26Mg, δ
29Si–δ
30Si, and δ
25Mg–δ
29Si spaces. The correlations between O-, Mg, and Si-isotopic compositions are best explained by Galactic chemical evolution (GCE), with only minor imprints of nucleosynthetic and mixing processes in the grains’ parent stars. Six Group 1 silicate (“category B”) grains have close-to-normal Mg and Si isotopic compositions, possibly the result of isotope exchange in interstellar space or the meteorite parent bodies. For Si in category A grains, we find, with ∼2σ significance, a slightly shallower slope in the δ
29Si–δ
30Si space for the GCE than inferred from presolar SiC mainstream grains. The 2σ upper limit on the slope for the linear trend in the δ
25Mg–δ
26Mg space of category A grains is slightly lower than the slope-1 predicted by GCE models around solar metallicity.
Climate Modeling of a Potential ExoVenus

The planetary mass and radius sensitivity of exoplanet discovery capabilities has reached into the terrestrial regime. The focus of such investigations is to search within the Habitable Zone where a modern Earth-like atmosphere may be a viable comparison. However, the detection bias of the transit and radial velocity methods lies close to the host star where the received flux at the planet may push the atmosphere into a runaway greenhouse state. One such exoplanet discovery, Kepler-1649b, receives a similar flux from its star as modern Venus does from the Sun, and so was categorized as a possible exoVenus. Here we discuss the planetary parameters of Kepler-1649b in relation to Venus to establish its potential as a Venus analog. We utilize the general circulation model ROCKE-3D to simulate the evolution of the surface temperature of Kepler-1649b under various assumptions, including relative atmospheric abundances. We show that in all our simulations the atmospheric model rapidly diverges from temperate surface conditions toward a runaway greenhouse with rapidly escalating surface temperatures. We calculate transmission spectra for the evolved atmosphere and discuss these spectra within the context of the James Webb Space Telescope Near-Infrared Spectrograph capabilities. We thus demonstrate the detectability of the key atmospheric signatures of possible runaway greenhouse transition states and outline the future prospects of characterizing potential Venus analogs.
Seismic safety evaluation during site selection for the nuclear power plants in Bangladesh
Authors: Shcheklein Sergey , Hossain Ismail , Akbar Mohammad , Velkin Vladimir

Bangladesh lies in a tectonically active zone. Earlier geological studies show that Bangladesh and its adjoining areas are exposed to a threat of severe earthquakes. Earthquakes may have disastrous consequences for a densely populated country. This dictates the need for a detailed analysis of the situation prior to the construction of nuclear power plant as required by the IAEA standards. This study reveals the correlation between seismic acceleration and potential damage. Procedures are presented for investigating the seismic hazard within the future NPP construction area. It has been shown that the obtained values of the earthquake’s peak ground acceleration are at the level below the design basis earthquake (DBE) level and will not lead to nuclear power plant malfunctions. For the most severe among the recorded and closely located earthquake centers (Madhupur) the intensity of seismic impacts on the nuclear power plant site does not exceed eight points on the MSK-64 scale. The existing predictions as to the possibility of a super-earthquake with magnitude in excess of nine points on the Richter scale to take place on the territory of the country indicate the necessity to develop an additional efficient seismic diagnostics system and to switch nuclear power plants in good time to passive heat removal mode as stipulated by the WWER 3+ design. A conclusion is made that accounting for the predicted seismic impacts in excess of the historically recorded levels should be achieved by the establishment of an additional efficient seismic diagnostics system and by timely switching the nuclear power plants to passive heat removal mode with reliable isolation of the reactor core and spent nuclear fuel pools.

The fractal dimension (FD) is calculated for seven species of the genus Quercus L. in Calabria region (southern Italy), five of which have a marcescent-deciduous and two a sclerophyllous character. The fractal analysis applied to the leaves reveals different FD values for the two groups. The difference between the means and medians is very small in the case of the marcescent-deciduous group and very large when these differences are established between both groups: all this highlights the distance between the two groups in terms of similarity. Specifically, Q.crenata, which is hybridogenic in origin and whose parental species are Q.cerris and Q.suber, is more closely related to Q.cerris than to Q.suber, as also expressed in the molecular analysis. We consider that, in combination with other morphological, physiological and genetic parameters, the fractal dimension is a useful tool for studying similarities amongst species.
La compétitivité des territoires de l’innovation confrontés aux crises et à la démondialisation : le cas de Sophia-Antipolis
Authors: Grondeau Alexandre
Published: December 2018

Dans le cadre de la mondialisation et de la concurrence internationale que se livrent les États, les régions et les métropoles, l’aménagement des territoires de l’innovation et leur compétitivité sont devenus des enjeux stratégiques du développement local. Sophia-Antipolis, premier technopôle d’Europe est une bonne illustration des différents types de stratégies que les responsables territoriaux ont menés et mènent encore pour résister aux crises économiques et technologiques de ces quarante dernières années. Nous analyserons ici les différentes opérations d’aménagement et politiques mises en place depuis la création du technopôle en 1969 pour favoriser son dynamisme, son attractivité et sa capacité d’ancrage territorial. Nous verrons que, si le milieu innovateur local et ses réseaux ont toujours été encouragés par les institutions, ce sont la qualité du cadre et les conditions de vie sophipolitaines qui ont été déterminantes dans la pérennisation du technopôle et la rétention de ses actifs à haute valeur ajoutée quand certaines entreprises internationales emblématiques ont quitté Sophia-Antipolis. Nous étudierons enfin les politiques actuelles entreprises pour valoriser ce « cadre de vie idéal pour la vie des cadres » et ne pas le laisser se banaliser dans un contexte international hautement concurrentiel en matière de localisation des activités et et des emplois de haute technologie.
La chaussure à Romans-sur-Isère : de la capitale internationale à une renaissance territorialisée
Authors: Gros-Balthazard Marjolaine
Published: December 2018

Après plusieurs décennies d’extension de la mondialisation, la «  démondialisation  », entendue comme un processus de fermeture des économies nationales, pourrait restreindre les échanges internationaux. Qu’ils soient économiques ou identitaires, les motifs sous-tendant cette démondialisation appellent à relire les relations territoires/entreprises qui, depuis des décennies, n’ont de cesse d’évoluer. Dans ce contexte, nous faisons l’hypothèse que le renouvellement de l’activité industrielle peut être soutenu par sa territorialisation. Notre propos s’appuie sur le cas d’étude de Romans-sur-Isère (Drôme). Ces dernières années s’observent les signes d’un redéveloppement d’un tissu productif territorialisé autour de la chaussure sous des formes bien différentes de l’ancrage territorial ayant prévalu lors de l’apogée de la mono-industrie. Sans se construire en opposition à la mondialisation, les acteurs de ce renouveau imaginent collectivement des modèles économiques (production, distribution, organisation) hors mondialisation.
Réflexion sur le capitalisme territorial : ancrage et domination de Michelin à Clermont-Ferrand
Authors: Zanetti Thomas
Published: December 2018

Les entreprises transnationales sont aujourd’hui de plus en plus nomades. Ce mouvement de déterritorialisation s’accentue sous l’effet de la financiarisation qui détache les acteurs économiques des contraintes spatiales. Face à ce capitalisme financier concentré dans quelques espaces de commandement, il existe un autre modèle constitué par les firmes mondiales à fort enracinement, que nous proposons d’analyser à travers l’ancrage territorial de Michelin. Nous faisons alors l’hypothèse de l’existence d’un nouveau régime d’accumulation, celui du capitalisme territorial. Instrumentalisant le territoire selon ses intérêts, il est également caractérisé par une forme de responsabilité territoriale consentie en l’échange d’un pouvoir politique. Enfin, ce régime capitalistique permet de dépasser la contradiction entre nomadisme et ancrage, et de perpétuer la domination territoriale du capital.
Entreprises et territoires : entre délocalisations et relocalisations d’activités de production

Published: December 2018

La crise économique et financière de 2007-2008 a révélé l’importance du mouvement de désindustrialisation que subit la France. En effet, la conjoncture économique contemporaine et la montée des pays émergents accélèrent le processus ce qui présente une menace pour tous les pays anciennement industrialisés et pour la France en particulier. Cette accélération laisse entrevoir le risque d’une dégradation de l’emploi, en particulier à l’échelle régionale (Cedillo-Campos 2004). La période soulève de nombreuses questions sur l'avenir des activités et des productions existantes. Or, plusieurs éléments pourraient modifier la géographie de production en favorisant les retours de production. Sommes-nous face à un phénomène anecdotique, ponctuel ou face à un renversement de tendance à plus long terme ? Quels impacts pourraient avoir ces relocalisations sur le tissu économique, les secteurs d’activité et les bassins d’emplois ?
