Published: October 2019

The fingerprint identification system is nowadays the biometric sector that is most exploited. Segmentation of the fingerprint image is considered as one of its first stage of processing.This stage thus typically affects the extraction and matching process of the feature, resulting in a high accuracy fingerprint recognition system.Three important steps are proposed in this paper. First, to improve the quality of the fingerprint images, Soble and TopHat filtering method were used.K-means clustering for combining 5-dimensional vector characteristics (variance, mean difference, gradient coherence, ridge direction, and energy spectrum) then accurately separates the foreground and background region for each local block in a fingerprint image.Also, local variance thresholding is used in our approach to reducing computing time for segmentation. Finally, we are combined with our DBSCAN clustering system that was performed to overcome the disadvantages of classifying K-means in the segmentation of fingerprint images.In four different databases, the proposed algorithm is tested. Experimental results show that our approach is significantly effective in the separation between the ridge and non-ridge region against some recently published techniques.

Penerapan Kalman Filter Pada Metode Trilaterasi Untuk Peningkatan Akurasi Estimasi Perhitungan Jarak Di Dalam Ruangan
Authors: Wibowo Fahrudin , Burhanudin Aulia
Published: October 2019

Penelitian tentang posisi maupun jarak suatu obyek di dalam ruangan telah banyak dilakukan. Metode trilaterasi adalah salah satu metode yang dapat dipergunakan untuk menghitung nilai estimasi jarak atau posisi suatu obyek di dalam ruangan, berdasarkan nilai RSSI (Received Signal Strength Indication) yang diterima suatu receiver. Namun, nilai RSSI yang diterima tidak dapat stabil dikarenakan sinyal yang diterima oleh receiver sangat dipengaruhi kondisi lingkungan pada ruangan yang pada umumnya memiliki nilai noise yang cukup tinggi. Sehingga dapat berakibat pada nilai estimasi jarak yang diperoleh menjadi kurang akurat. Sehubungan dengan hal tersebut maka setelah dilakukan perhitungan dengan trilaterasi, dilanjutkan dengan menambahkan metode Kalman Filter untuk meningkatkan nilai akurasi. Penelitian ini menggunakan BLE (Bluetooth Low Energy) sebagai transmitter, sedangkan receiver menggunakan smartphone yang sudah ter-install aplikasi untuk menerima nilai RSSI. Setelah menggunakan Kalman Filter diperoleh peningkatan nilai akurasi sebesar 0, 1 meter dari nilai perhitungan trilaterasi

Ascensão e Queda do Brasil como Doador de Assistência Humanitária Internacional
Authors: Tambourgi Patricia Vilarinho
Published: October 2019

O Brasil completou, em 2015, uma década de atuação como doador de assistência humanitária internacional. A inserção brasileira acontece em momento em que outros países em desenvolvimento também começam a atuar do lado da oferta de assistência humanitária. Tradicionalmente, os países membros do Comitê de Assistência ao Desenvolvimento, da Organização para a Cooperação e Desenvolvimento Econômico (DAC/OECD) são considerados os principais doadores internacionais. A emergência de novos atores estatais, os doadores “Não DAC”, agrega mais recursos ao total de oferta de assistência humanitária. Neste artigo, o Brasil aparece como um doador Não DAC, sendo apresentada a inserção internacional brasileira como do país doador do ponto de vista financeiro das ações em relação à sua política externa.
Palavras-chave: governo Lula; assistência humanitária internacional; política externa brasileira; CGFOME; governo Dilma.

American structural power within International Financial Governance: from Bretton Woods to globalization
Authors: Alencar Fernando Barcellos de Andrade
Published: October 2019

From the 1950s to the 1990s, the international monetary and financial system underwent deep changes with profound consequences, including the breakdown of Bretton Woods and the emergence of the globalized financial system. This paper aims to understand how American domestic political and economic challenges and responses in the 1970s reframed the superpowers’ foreign policy goals with respect to global financial governance. Drawing on the international political economy theory of structural power, this article analyzes U.S. domestic and foreign economic policy and examines international governance outcomes from a historical perspective. It argues that U.S. replies to domestic and international political and economic constraints prompted significant structural changes to the international monetary and financial system. The paper concludes that it is American domestic decision-making that determines the structure of the international financial system due to American structural power to underwrite and rewrite the norms and rules of the international financial governance.

Ciclos políticos hegemónicos: implicaciones para la gobernanza internacional
Authors: Morales Ruvalcaba Daniel
Published: October 2019

El hegemón es un actor fundamental en la gobernanza internacional. No obstante, mientras que el comercio, poder y guerra han sido temas ampliamente abordados desde los estudios sobre hegemonía en las Relaciones Internacionales, se ha avanzado poco en análisis de las ideas que orientan el comportamiento del hegemón. La hipótesis aquí planteada es que las hegemonías recorren a lo largo de su existencia cinco fases (emergencia, despliegue, apogeo, declive y extinción) y, durante cada una de ellas, el Estado hegemónico asume ideologías específicas que orientan su comportamiento internacional, lo cual se traduce en la promoción de ciertas políticas internacionales, así como de alianzas y organizaciones internacionales con vocaciones específicas. Sin embargo, en la medida que evoluciona su poder nacional y el hegemón transita de una fase a otra, éste tiende a cambiar ideológicamente, abandonando ideas previas y asumiendo otras nuevas. Si bien dicha transición ideológica es pragmática -en función de las necesidades de su poder nacional- este cambio resulta discordante y criticable por otros actores del sistema. Este documento se compone de dos grandes partes: en la primera se establecen las cinco fases de un ciclo hegemónico y, luego, se exponen las ideologías que orientan el comportamiento del Estado hegemónico en ellas; la segunda parte se orienta a comprobar empíricamente las transiciones ideológicas durante las hegemonías neerlandesa, británica y estadounidense.

 

Abstract: The hegemon is a fundamental actor in international governance. However, while trade, power and war have been topics widely discussed from studies on hegemony in International Relations, little progress has been made in analyzing the ideas that guide the behavior of the hegemon. The hypothesis proposed here is that the hegemonies pass through five phases during their existence (emergence, deployment, apogee, decline and extinction) and, during each of them, the hegemonic State assumes specific ideologies that guide its international behavior. However, as the national power evolves, and the hegemon moves from one phase to another, it tends to change ideologically, abandoning previous ideas and assuming new ones. Although this ideological transition is pragmatic - depending on the power needs of the hegemon- this change results discordant and is criticized by other actors in the system. To demonstrate this, the following document is composed of two major parts: the first presents the five phases of a hegemonic cycle and, along with it, the ideologies that guide the behavior of the hegemonic State; the second part aims to empirically verify the ideological transitions during the hegemonies that have existed: the Dutch, the British and the American.

Keywords: Hegemony, hegemonic political cycles, ideology, national power, hegemonic interregnum.

Reascensão da política de segurança russa na Ásia Central por meio da Organização para Cooperação de Xangai (OCX)
Authors: Leite Alexandre César Cunha , Lucena Arthur Mastroiani Maximo de , Nobre Fábio
Published: October 2019

O artigo tem como finalidade abordar a expansão da política externa da Rússia na Ásia Central, com método dedutivo e estudo de caso na Organização para Cooperação de Xangai (OCX), tomando esta como uma Instituição cujo objetivo é a segurança coletiva dos seus países membros. Partindo do momento em que Vladimir Putin assume o poder já no início do século XXI até o ano de 2015, visto que são os anos cruciais em que o país inicia sua reascensão no cenário internacional, a Rússia, bem como a China, atores mais importantes dentro da (OCX), atuam juntos contra o terrorismo, movimentos separatistas, conflitos de fronteiras, tráfico de drogas, migração, dentre outras temáticas de segurança. Diante disto, por meio da Teoria dos Complexos Regionais de Segurança, será discutido como a Rússia tem feito sua expansão de política externa no âmbito de segurança na região da Ásia Central e como a Organização é fundamental neste processo, visto que a Rússia opta por ser um Estado forte e centralizador em seus assuntos de política externa e a sua participação na Organização é um instrumento internacional importante de atuação, com o seguinte problema de pesquisa: Diante da reascensão da Rússia no cenário internacional no século XXI, como o país consegue impor sua agenda de política externa em segurança na Ásia Central, por meio da Organização para Cooperação de Xangai?
 
 
Abstract: This paper aims to address and expand Russia's foreign policy in Central Asia, with deductive method and study of case in Organization for collective security of its members called the Shanghai Cooperation Organization (SCO), starting from the moment that Vladimir Putin assumes power no longer the beginning of the 21st century, since it is one of the crucial moments in which Russia begins its re-emergence on the international stage. As the main focus of the Organization and a collective security, a Russia, as well as a China, major actors within the International Organization, (OCX), act together against terrorism, separatist movements, border conflicts, drug trafficking, migration, among other security topics. Moreover, by means of the Regional Security Complex Theory, it will be discussed how Russia has made its foreign policy expansion in the Central Asian region and how the Organization is fundamental in this process, since Russia chooses to be a strong and centered on its foreign policy issues and its role in the Organization is an important international instrument of action, with the following research problem: Facing Russia's re-emergence on the international stage in the 21st century, which extent the country manages to impose its security agenda in Central Asia, through the Shanghai Cooperation Organization?

Os Estados Unidos: A Geopolítica e a Geoeconomia da Energia
Authors: Pecequilo Cristina S , Jaeger Bruna Coelho
Published: October 2019

Dos séculos XX ao XXI, os Estados Unidos têm desempenhado um papel significativo na agenda da geopolítica e da geoeconomia da energia, com impactos sobre todo o sistema internacional. A questão energética envolve tanto a temática de segurança quanto a econômica norte-americana, gerando efeitos internos e externos para o país. Neste contexto, a emergência de novos desafiadores internacionais no mercado da energia, como produtores e consumidores, o desenvolvimento de regimes internacionais ambientais que afetam as matrizes energéticas acentuam a importância do tema para as relações internacionais. O objetivo do texto é avaliar, a partir de uma breve contextualização histórica a evolução da questão energética para os Estados Unidos, e conjunturalmente a ação da gestão republicana de Donald Trump na Casa Branca e seus impactos sobre a continuidade e descontinuidade da projeção de poder norte-americana no setor energético. Desta forma, procurar-se-á ressaltar a trajetória da securitização energética no país, os efeitos sobre as agendas estratégicas e econômicas nacionais e as interações com o cenário global, em suas dimensões multilaterais e estatais.

 

 

Abstract: From the 20th till the 21st century, the United States have been playing a significant role in the geopolitical and geoeconomic energy agenda, with impacts for the whole international system. The energy issue comprehends not only security, but also economic policies for the Americans, with domestic and external effects for the country. In this context, the emergence of new international contenders in the energy market, either as producers or consumers, and the development of international environmental regimes that affect the energy matrix deepen the relevance of this theme for international relations. The goal of the text is to evaluate, starting with a brief historical account, the evolution of the energy issue in the US, and nowadays the actions of Trump´s Republican government leading the White House, and its impacts for the continuity or break of American power projection in the energy sector. So, we will try to present the path of securitization of the country´s energy issued, and the effects on the national strategic and economic agendas, and their link with the global scenario, considering its multilateral and state´s dimensions.

inserção contemporânea do México na América Latina: das crises diplomáticas à Aliança do Pacífico
Authors: Walid de Magalhães Naddi Beatriz
Published: October 2019

Este início do século XXI apresentou ao México três grandes desafios: i) a dependência econômica aos EUA, que vem enfrentando um declínio econômico; ii) a ascensão da região Ásia-Pacífico como maior centro dinâmico; e iii) seu afastamento das principais iniciativas de integração na América Latina na atualidade. Com base nesse cenário, este artigo visa analisar a inserção contemporânea do México na América Latina, tomando como objeto de análise os governos de Vicente Fox (2000-2006), Felipe Calderón (2006-2012) e Henrique Peña Nieto (2012-2018). Para isso, são avaliados os parâmetros conceituais da inserção mexicana na América Latina, em seguida as características gerais da política externa dos governos selecionados, para, então, se adentrar na análise da relação desses com a região, dedicando, ao final, uma análise especial à Aliança do Pacífico.

Neural tracking of subjective value under riskand ambiguity in adolescence
Authors: Blankenstein Neeltje E. , van Duijvenvoorde Anna C. K.
Published: October 2019

Although many neuroimaging studies on adolescent risk taking have focused on brain activation during outcome valuation, less attention has been paid to the neural correlates of choice valuation. Subjective choice valuation may be particularly influenced by whether a choice presents risk (known probabilities) or ambiguity (unknown probabilities), which has rarely been studied in developmental samples. Therefore, we examined the neural tracking of subjective value during choice under risk and ambiguity in a large sample of adolescents (N = 188, 12–22 years). Specifically, we investigated which brain regions tracked subjective value coding under risk and ambiguity. A model-based approach to estimate individuals’ risk and ambiguity attitudes showed prominent variation in individuals’ aversions to risk and ambiguity. Furthermore, participants subjectively experienced the ambiguous options as being riskier than the risky options. Subjective value tracking under risk was coded by activation in ventral striatum and superior parietal cortex. Subjective value tracking under ambiguity was coded by dorsolateral prefrontal cortex (PFC) and superior temporal gyrus activation. Finally, overlapping activation in the dorsomedial PFC was observed for subjective value under both conditions. Overall, this is the first study to chart brain activation patterns for subjective choice valuation under risk and ambiguity in an adolescent sample, which shows that the building blocks for risk and ambiguity processing are already present in early adolescence. Finally, we highlight the potential of combining behavioral modeling with fMRI for investigating choice valuation in adolescence, which may ultimately aid in understanding who takes risks and why.
Improvement of the thermoelectric properties of a MoO3 monolayer through oxygen vacancies
Authors: Zheng Wenwen , Cao Wei , Wang Ziyu , Deng Huixiong , Shi Jing , Xiong Rui
Published: October 2019

We have investigated the thermoelectric properties of a pristine MoO3 monolayer and its defective structures with different oxygen vacancies using first-principles methods combined with Boltzmann transport theory. Our results show that the thermoelectric properties of the MoO3 monolayer exhibit an evident anisotropic behavior which is caused by the similar anisotropy of the electrical and thermal conductivity. The thermoelectric materials figure of merit (ZT) value along the x- and the y-axis is 0.72 and 0.08 at 300 K, respectively. Moreover, the creation of oxygen vacancies leads to a sharp peak near the Fermi level in the density of states. This proves to be an effective way to enhance the ZT values of the MoO3 monolayer. The increased ZT values can reach 0.84 (x-axis) and 0.12 (y-axis) at 300 K.
LAND CADASTRE DEVELOPMENT IN UKRAINE: ISSUES TO BE ADDRESSED
Authors: Popov Andriy
Published: October 2019

Cadastral information is a key component for many land use functions and a core to the effective land markets, land use and sustainable development. These applications require up-to-date, reliable and complete data. This paper focuses on one aspect of land cadastre – identification of the objects of the cadastre. The characteristics and development of the existing cadastral system are discussed. We follow an empirical approach and propose an overview how and in what form the objects of state land cadastre are identified and registered in Ukraine. The paper analyses the problems associated with the plurality of the land cadastre objects. It is proposed to remove the registration numbers of the state land cadastre objects and new cadastral numbers of the land parcel from the legislation and return the legalization of the old cadastral number of the land parcel. The paper also underlines the necessity to consider the land parcel as a single object of the state land cadastre. Finally, it is proposed that the cadastral number of restrictions in the use of the land parcel will be an immense advantage in land registration and in visualisation the restrictions on the public cadastral map of Ukraine.
METHODOLOGICAL APPROACH TO THE INTEGRAL ASSESSMENT OF THE REGIONAL LANDS USE TERRITORIAL DEVELOPMENT
Authors: Mamonov Kostiantyn
Published: October 2019

The relevance of the research topic is caused by the need to ensure the territorial development of land use at the regional level. In this context, it is necessary to form a quantitative basis for assessing territorial development, which will make decisions in the field of land use and ensure the growth of land use efficiency in the region, considering spatial, urban planning, ecological and investment areas. As a result of the study, a methodological approach to the integrated assessment of the territorial development of land use in the region has been proposed. Its development is based on the application of principles and includes a set of interrelated stages. It was established that the formation of a complex of spatial, urban planning, investment, and ecological factors, which influence the territorial development of land use in the region is carried out on the basis of the analysis and systematization of existing scientific and methodological developments and regulatory support. An algorithm for the development and implementation of a methodological approach to an integrated assessment of the territorial development of land use in the region is proposed. It forms a closed system, which allows to develop and implement a methodological approach by applying of information support, appropriate methods and models to achieve a result on the growth of the integral indicator of land use in the region, considering spatial, urban planning, investment, and ecological characteristics. Based on the developed method, an estimated basis for the territorial development of land use in the region, adoption of justified decisions, regarding the formation and implementation of spatial, urban planning, investment, and ecological areas is created.

Tidal Disruption Events, Main-sequence Extreme-mass Ratio Inspirals, and Binary Star Disruptions in Galactic Nuclei
Authors: Sari Re’em , Fragione Giacomo
Published: October 2019

The Galactic Center has been under intense scrutiny in recent years thanks to pioneering missions aiming to measure the gas and star dynamics near the supermassive black hole (SMBH) and to find the gravitational-wave (GW) signatures of inspiraling stellar black holes. In the crowded environment of galactic nuclei, the two-body interactions alter the distribution of stars on long timescales, making them drift in energy and angular momentum. We present a simplified analytical treatment of the scattering processes in galactic stellar nuclei, assuming all stars have the same mass. We have discussed how the interplay between two-body relaxation and GW emission modifies the slope of the inner stellar cusp within the SMBH sphere of influence, and calculated the rates of tidal disruption events (TDEs) and main-sequence extreme-mass ratio inspirals (MS-EMRIs) of stars that are tidally disrupted by the SMBH. We find that typically the ratio of the TDE and MS-EMRI rates is the square of the ratio of the tidal and Schwarzschild radii. For our Galaxy, this implies that the rate of MS-EMRIs is just about a percent of the TDE rate. We then consider the role of stars injected on highly eccentric orbits in the vicinity of the SMBH due to the Hills binary disruption mechanism, and show that the MS-EMRI rate can almost approach the TDE rate if the binary fraction at the SMBH influence radius is close to unity. Finally, we discuss how physical stellar collisions affect a large area of phase space.

Radio emission in jets from young stellar objects (YSOs) in the form of nonthermal emission has been seen toward several YSOs. Thought to be synchrotron emission from strong shocks in the jet, it could provide valuable information about the magnetic field in the jet. Here we report on the detection of synchrotron emission in two emission knots in the jet of the low-mass YSO DG Tau A at 152 MHz using the Low-Frequency Array, the first time nonthermal emission has been observed in a YSO jet at such low frequencies. In one of the knots, a low-frequency turnover in its spectrum is clearly seen compared to higher frequencies. This is the first time that such a turnover has been seen in nonthermal emission in a YSO jet. We consider several possible mechanisms for the turnover and fit models for each of these to the spectrum. Based on the physical parameters predicted by each model, the Razin effect appears to be the most likely explanation for the turnover. From the Razin effect fit, we can obtain an estimate for the magnetic field strength within the emission knot of ∼20 μG. If the Razin effect is the correct mechanism, this is the first time that the magnetic field strength along a YSO jet has been measured based on a low-frequency turnover in nonthermal emission.
The Influence of Gas-phase Chemistry on Organic Haze Formation

Although photochemically produced organic hazes are common in planetary atmospheres, there have been few experimental investigations of the gas-phase chemistry leading to organic haze formation. We report a laboratory study of the gas-phase compounds formed by far-ultraviolet irradiation of a CH4/N2 mixture. Using high-resolution chemical ionization mass spectrometry (CIMS) we made in situ measurements of gas-phase products up to m/z 400. Organic nitrogen species dominate the mass spectra with smaller contributions from unsaturated hydrocarbons. Using a structural group method to estimate vapor pressures, we calculate that for compounds detected at m/z > 320, ≥50% of the total compound loading (gas + condensed phase) would be present in the condensed (aerosol) phase at 300 K. Using approximations for changes in vapor pressure with temperature, we estimate that ≥50% of the total loading for species with m/z > 110 would be in the aerosol-phase at 150 K, suggesting that the measured compounds may be important for aerosol composition for a range of temperatures. Finally, we leverage the sensitivity and fast time response of the CIMS measurements to investigate how the gas-phase chemistry evolved over the course of the experiment. This analysis shows that hydrocarbons were the initial products followed by the formation of unsaturated organic nitrogen compounds. Higher molecular weight species and alkylamines appear late in the experiment. Comparison of our measurements to chemical mechanisms used to model planetary haze formation suggests that larger molecular weight compounds need to be considered in haze formation chemistry.
Interprétation et homophonie
Authors: Lauru Didier
Published: October 2019

Les différents types d’interprétation sont étudiés d’après les indications de Lacan. La première partie de cet article tente de définir ce qu’est une interprétation dans la cure analytique. L’une d’entre elles est développée plus précisément, l’homophonie. C’est-à-dire une interprétation basée sur la révélation ou l’éclairage d’un patient vers la possibilité d’entendre ou de comprendre d’autres façons ce qu’il vient d’énoncer, et plus particulièrement, ce qui n’a pu être entendu ou compris autrement. Des fragments de cure analytique donnent un exemple de ce qu’est une interprétation homophonique et de ses possibles effets dans le transfert et dans l’analyse.
Addressing the Health Risks of Climate Change in Older Adults

Published: October 2019

Our climate is changing. These changes have an impact on health, especially in vulnerable populations such as older adults. Many older adults lack the physical, cognitive, social, and economic resources to avoid and/or mitigate the effects of exposure to extreme weather events. The purpose of the current article is to help nurses understand climate change and how that relates to the need for specific interventions to support climate adaptation for the older adult population. A model of exposure, contact to stressors, and adaptive capacity are used to address the health needs of older adults in the face of climate change. Gaps in nursing knowledge, resources for nurses, and a proposed agenda for research and practice in climate change are offered. Gerontological nurses are in an important position to lessen the harm of climate change in older adults through practice, research, and policy. [

Un quartier de la ville antique de Vesontio (Besançon)
Authors: Gaston Christophe , Munier Claudine
Published: October 2019

La fouille réalisée entre 2010 et 2012 sur le site des Passages Pasteur à Besançon a mis en évidence un quartier antique s’organisant autour d’une rue secondaire. Douze parcelles ont pu être définies dans l’emprise du chantier, pour une occupation s’étalant de 40 de notre ère jusqu’au milieu du ive siècle. Les parcelles tournées vers la rue sont occupées par des maisons de commerçants et d’artisans, alors que les parcelles tournées vers le Doubs appartiennent à des domus plus vastes, demeures de familles plus aisées. Les deux principales activités rencontrées dans ce quartier correspondent d’une part aux métiers de bouche, se déclinant en stockage alimentaire, boulangerie, meunerie, fumaison-salaison et restauration (auberge), et d’autre part au travail du métal (forge et travail des alliages base-cuivre). Ces activités se côtoient et se croisent régulièrement au sein d’une même parcelle.
La greffe et l’empreinte : chiisme et communisme dans le monde arabe
Authors: Dot-Pouillard Nicolas
Published: October 2019

Le communisme et l’islam politique chiite dans le monde arabe ne partagent pas les mêmes présupposés idéologiques, mais une série de greffes et d’empreintes successives, notamment en Irak et au Liban, leur donne parfois un air de famille. Trois séquences historiques distinctes se dessinent. À partir des années 1950, des partis communistes se greffent sur des communautés chiites marginalisées : l’appel révolutionnaire du marxisme et de la lutte des classes fait pratiquement écho au millénarisme chiite. Avec les effets de la révolution iranienne de 1979 sur le monde arabe, la dynamique s’inverse : la tonalité anti-impérialiste et eschatologique venue de Téhéran fascine les gauches marxisantes. Elle encourage des conversions à l’islam politique. La troisième séquence s’ouvre avec les années 1990 ; depuis, le communisme arabe a un usage politique du chiisme, mais qui n’est pas religieux. En se plaçant du côté de Téhéran et du Hezbollah libanais, les gauches marxisantes tentent de réenchanter une vision tiers-mondiste du politique. Mais, à l’instar de l’islam politique chiite, elles ont pour le moment abandonné tout horizon révolutionnaire.
Le chiite imaginaire
Authors: Geisser Vincent
Published: October 2019

Comment expliquer la montée de représentations anti-chiites au sein du champ musulman français, en dépit de l’invisibilité des communautés chiites et de leur absence des institutions de l’islam en France ? C’est à cette énigme que s’attelle cet article, en analysant les temporalités, les répertoires et les acteurs de cet « anti-chiisme sans chiites ». Certes, ce processus est influencé par les prédicateurs et les théologiens d’obédience sunnite traditionaliste et hanbalo-wahhabite. Mais il serait réducteur de l’interpréter comme l’expression d’un anti-chiisme « importé » qui prolongerait les controverses religieuses et politiques dominant les scènes islamiques du Moyen-Orient. Car cet anti-chiisme épouse largement les enjeux et les clivages qui caractérisent le champ musulman français. Il n’est plus simplement véhiculé par les milieux salafistes traditionnellement hostiles au chiisme mais aussi par des leaders musulmans « réformistes » issus des nouvelles générations socialisées en France, qui trouvent dans l’anti-chiisme une manière d’affirmer leur autorité spirituelle et communautaire.
De la « Défense sacrée » (1980-1988) à la « Défense des Lieux saints » (2012-2017)
Authors: Devictor Agnès
Published: October 2019

En s’appuyant sur un grand nombre de films et d’images, cet article rend compte de la constitution des imaginaires de guerre au cours de deux conflits armés où la République islamique d’Iran a été partie prenante : la guerre contre l’Irak (1980-1988), première guerre filmée, puis officiellement la guerre contre l’État Islamique en Syrie et en Irak entre 2012 et 2017. Il analyse comment, pour définir et raconter une communauté combattante et contribuer à la mobilisation nationale entre 1980 et 1988, des réalisateurs ont mis en scène le grand récit de la bataille de Karbalâ, développant pour certains une expression chiite , tant sur le plan narratif que formel, quand d’autres réalisateurs usaient de références détachées de tout lien religieux. L’article interroge ensuite les reformulations du « paradigme de Karbalâ » auxquelles procède le traitement cinématographique de la guerre contre l’État Islamique, et se propose d’identifier les nouvelles pensées de l’image qui en émergent.
