A Low-Cost Tracking System for Running Race Applications Based on Bluetooth Low Energy Technology
Authors: Perez-Diaz-de-Cerio David , Hernández-Solana Ángela , Valdovinos Antonio , Valenzuela Jose
Published: March 2018

Timing points used in running races and other competition events are generally based on radio-frequency identification (RFID) technology. Athletes’ times are calculated via passive RFID tags and reader kits. Specifically, the reader infrastructure needed is complex and requires the deployment of a mat or ramps which hide the receiver antennae under them. Moreover, with the employed tags, it is not possible to transmit additional and dynamic information such as pulse or oximetry monitoring, alarms, etc. In this paper we present a system based on two low complex schemes allowed in Bluetooth Low Energy (BLE): the non-connectable undirected advertisement process and a modified version of scannable undirected advertisement process using the new capabilities present in Bluetooth 5. After fully describing the system architecture, which allows full real-time position monitoring of the runners using mobile phones on the organizer side and BLE sensors on the participants’ side, we derive the mobility patterns of runners and capacity requirements, which are determinant for evaluating the performance of the proposed system. They have been obtained from the analysis of the real data measured in the last Barcelona Marathon. By means of simulations, we demonstrate that, even under disadvantageous conditions (50% error ratio), both schemes perform reliably and are able to detect the 100% of the participants in all the cases. The cell coverage of the system needs to be adjusted when non-connectable process is considered. Nevertheless, through simulation and experimental, we show that the proposed scheme based on the new events available in Bluetooth 5 is clearly the best implementation alternative for all the cases, no matter the coverage area and the runner speed. The proposal widely exceeds the detection requirements of the real scenario, surpassing the measured peaks of 20 sensors per second incoming in the coverage area, moving at speeds that range from 1.5 m/s to 6.25 m/s. The designed real test-bed shows that the scheme is able to detect 72 sensors below 600 ms, fulfilling comfortably the requirements determined for the intended application. The main disadvantage of this system would be that the sensors are active, but we have proved that its consumption can be so low (9.5 µA) that, with a typical button cell, the sensor battery life would be over 10,000 h of use.

Published: March 2018

Deep learning has recently attracted much attention due to its excellent performance in processing audio, image, and video data. However, few studies are devoted to the field of automatic modulation classification (AMC). It is one of the most well-known research topics in communication signal recognition and remains challenging for traditional methods due to complex disturbance from other sources. This paper proposes a heterogeneous deep model fusion (HDMF) method to solve the problem in a unified framework. The contributions include the following: (1) a convolutional neural network (CNN) and long short-term memory (LSTM) are combined by two different ways without prior knowledge involved; (2) a large database, including eleven types of single-carrier modulation signals with various noises as well as a fading channel, is collected with various signal-to-noise ratios (SNRs) based on a real geographical environment; and (3) experimental results demonstrate that HDMF is very capable of coping with the AMC problem, and achieves much better performance when compared with the independent network.
On the Adequacy of API 521 Relief-Valve Sizing Method for Gas-Filled Pressure Vessels Exposed to Fire
Authors: Andreasen Anders , Borroni Filippo , Zan Nieto Marcos , Stegelmann Carsten , P. Nielsen Rudi
Published: March 2018

In this paper, the adequacy of the legacy API 521 guidance on pressure relief valve (PRV) sizing for gas-filled vessels subjected to external fire is investigated. Multiple studies show that in many cases, the installation of a PRV offers little or no protection—therefore provides an unfounded sense of security. Often the vessel wall will be weakened by high temperatures, before the PRV relieving pressure is reached. In this article, a multiparameter study has been performed taking into consideration various vessel sizes, design pressures (implicitly vessel wall thickness), vessel operating pressure, fire type (pool fire or jet fire) by applying the methodology presented in the Scandpower guideline. A transient thermomechanical response analysis has been carried out to accurately determine vessel rupture times. It is demonstrated that only vessels with relatively thick walls, as a result of high design pressures, benefit from the presence of a PRV, while for most cases no appreciable increase in the vessel survival time beyond the onset of relief is observed. For most of the cases studied, vessel rupture will occur before the relieving pressure of the PRV is reached.
Youth Work and Serendipity: Some Anthropological Implications
Authors: Pozzoni Federico
Published: March 2018

This article explores the anthropological notion and methodology of serendipity as applied to youth work and non-formal education training methods. I introduce the term and its uses by drawing connections to the concept of ethnographic fieldwork and strategy to approach anthropological contexts. I then draw a parallel between the role of the anthropologist and the youth worker. I investigate the different options when dealing with groups and facing the contradictions of conducting fieldwork or trainings. Thus, I propose a distinction between the anthropological concept of ‘serendipity’ and the youth work-related concept of ‘improvisation’. I present ambiguous cases of the serendipity process and their implications based on my own direct experience of involvement with youth work through the methodology of autoethnography. Finally, I address different perspectives of serendipity seen as a storytelling construction. Ultimately, I draw useful conclusions on the understanding of serendipity and improvisation in the two contexts.
Nonviolence and Religion: Creating a Post-Secular Narrative with Aldo Capitini
Authors: Baldoli Roberto
Published: March 2018

This article argues that nonviolence is a valid framework for religions to build up a post-secular narrative. Drawing from the approach of Aldo Capitini, I claim that religions can choose nonviolence as a religious path to integrate the different narratives of secularism via the concepts and practices of liberation and openness. In particular, nonviolence adds self-rule to an immanent framework; it offers resilience to the society; and it adds “the heroism of peace” to the political sphere. The result is the construction via facti of an innovative post-secular narrative.
New Integrated Quality Function Deployment Approach Based on Interval Neutrosophic Set for Green Supplier Evaluation and Selection
Authors: Van Luu , Yu Vincent , Dat Luu , Dung Canh , Chou Shuo-Yan , Loc Nguyen
Published: March 2018

Green supplier evaluation and selection plays a crucial role in the green supply chain management of any organization to reduce the purchasing cost of materials and increase the flexibility and quality of products. An interval neutrosophic set (INS)—which is a generalization of fuzzy sets, intuitionistic fuzzy sets (IFS) and neutrosophic sets (NS)—can better handle the incomplete, indeterminate and inconsistent information than the other sets. This paper proposes a new integrated Quality Function Deployment (QFD) in support of the green supplier evaluation and selection process. In the proposed approach, INS is used to assess the relative importance of the characteristics that the purchased product should have (internal variables “WHATs”) in order to satisfy the company’s needs, the relevant supplier assessment criteria (external variables “HOWs”), the “HOWs”-“WHATs” correlation scores, the resulting weights of the “HOWs” and the impact of each potential supplier. The normalized weighted rating is then defined and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method is developed to obtain a final ranking of green suppliers. A case study is applied to demonstrate the efficiency and computational procedure of the proposed method.
Phytoplankton as Key Mediators of the Biological Carbon Pump: Their Responses to a Changing Climate
Authors: Basu Samarpita , Mackey Katherine
Published: March 2018

The world’s oceans are a major sink for atmospheric carbon dioxide (CO2). The biological carbon pump plays a vital role in the net transfer of CO2 from the atmosphere to the oceans and then to the sediments, subsequently maintaining atmospheric CO2 at significantly lower levels than would be the case if it did not exist. The efficiency of the biological pump is a function of phytoplankton physiology and community structure, which are in turn governed by the physical and chemical conditions of the ocean. However, only a few studies have focused on the importance of phytoplankton community structure to the biological pump. Because global change is expected to influence carbon and nutrient availability, temperature and light (via stratification), an improved understanding of how phytoplankton community size structure will respond in the future is required to gain insight into the biological pump and the ability of the ocean to act as a long-term sink for atmospheric CO2. This review article aims to explore the potential impacts of predicted changes in global temperature and the carbonate system on phytoplankton cell size, species and elemental composition, so as to shed light on the ability of the biological pump to sequester carbon in the future ocean.
Plain and Ultrafine Fly Ashes Mortars for Environmentally Friendly Construction Materials
Authors: Coppola Luigi , Coffetti Denny , Crotti Elena
Published: March 2018

This paper is aimed to study the rheological and physical performance of mortars manufactured replacing Portland-based cements with low calcium siliceous fly ash (FA) or ultrafine fly ash (UFFA). Five different types of cement (CEM I, CEM II/A-LL, CEM III/A, CEM III/B, and CEM IV according to EN 197-1) were used. Mortars were manufactured with FA or UFFA replacing 5%, 15%, 25%, 35%, and 50% of cement mass. Results indicate that compressive strength of mortars with UFFA is considerably higher than that of mixtures containing traditional FA, both at early and long ages. Moreover, experimental data reveal that replacement of cement with up to 25% of UFFA determines higher compressive strength at 7, 28, and 84 days than plain mortars (containing cement only), regardless of the type of cement used. Mortars manufactured with 35% or 50% of UFFA show slightly lower or similar compressive strength compared to the reference mortar (containing cement only). In addition, the results show values of the strength activity index of mortars made with FA 25%, 23%, and 20% lower than the reference corresponding mortars (cement only) at 7, 28, and 84 days, respectively. The grinding of FA, despite resulting in an increase in production energy and CO2 emissions compared to unmilled FA, allows a wide use of these SCM (Supplementary Cementitious Materials) in place of cement, reducing the environmental impact of mortars up to 40% at the 28-day strength class. The use of UFFA ensures better resistance in CaCl2-rich environments.

Authors: Yan Min-Ren , Chien Kuo-Ming , Hong Lin-Ya , Yang Tai-Ning
Published: March 2018

National policies for science parks and innovation have been identified as one of the major driving forces for the innovation-driven economy, especially for publicly funded science parks. To investigate this collaborative ecosystem (government-academia-industry) for growth and sustainable development, this paper proposes a nation-wide economic impact analysis of science parks and innovation policy based on historical data drawn from one of the globally recognized high-technology industrial clusters in Taiwan. Systems thinking with causal loop analysis are adopted to improve our understanding of the collaborative ecosystem with science park policies. First, from a holistic viewpoint, the role of government in a science parks and innovation ecosystem is reviewed. A systems analysis of an innovation-driven economy with a science park policy is presented as a strategy map for policy implementers. Second, the added economic value and employment of the benchmarked science parks is evaluated from a long range perspective. Third, the concepts of government-academia-industry collaboration and policies to innovation ecosystem are introduced while addressing the measures and performance of innovation and applied R&D in the science parks. We conclude with a discussion of lessons learned and the policy implications of science park development and an innovation ecosystem.
A Multi-Response Optimization of Thrust Forces, Torques, and the Power of Tapping Operations by Cooling Air in Reinforced and Unreinforced Polyamide PA66
Authors: Domingo Rosario , De Agustina Beatriz , Marín Marta
Published: March 2018

The use of cooling air during machining is an environmentally conscious procedure, and its applicability to different processes is a research priority. We studied tapping operations, an important operation in the assembly process, using cooling air with unreinforced polyamide (PA66) and polyamide reinforced with glass fiber (PA66-GF30). These materials are widely used in industry, but their behavior with respect to tapping has not been studied. We analyze the outcomes regarding the thrust force, torque, and power at cutting speeds between 15 and 60 m/min. The experimental tests were executed using cooling air at 22 °C, 2 °C, and −18 °C in dry conditions. The M12 × 1.75 mm taps were high-speed steel, with cobalt as the base material and coatings of TiN and AlCrN. To identify the more influential factors, an analysis of variance was performed, along with multi-response optimization to identify the desirability values. This optimization shows that the optimum for PA66can be found in environments close to 3 °C, while the optimum for PA66-GF30 is found at the minimal temperature studied (−18 °C). Thus, cooling air can be considered an adequate procedure for tapping operations, to increase the sustainability of the manufacturing processes.
The Economic Impact of Government Policy on Market Prices of Low-Fat Pork in South Korea: A Quasi-Experimental Hedonic Price Approach
Authors: Kim Hyun , Choi Ik-Chang
Published: March 2018

The implementation of government policy can have an influence on market environment and market prices of pork in consequence. In South Korea, consumers prefer high-fat pork cuts due to the prevalence of roosting pork over a hot grill. This paper examines the impact of the government policy which aims to increase the consumption of low-fat pork cuts because of the concerns regarding asymmetric consumption between high-fat and low-fat pork cuts. Using hedonic price methods combined with quasi-experimental approaches we estimate the subsequent impact of food policy on the price of low-fat pork cuts using a time series of sales data. This study utilized an effective approach which has been widely employed for policy evaluation to produce plausible estimates of the economic values generated by the government policy. We find the existence of market segmentation and different impacts of the policy between markets. While the market price for high-fat pork cuts has remained stable, the price for low-fat pork cuts has slightly increased since the policy has been implemented. This paper illustrates that government’s policy can be a good strategy to maintain sustainability of the food industry by improving the balance in pork consumption and the management of stocks.
Casimir Energies for Isorefractive or Diaphanous Balls
Authors: Milton Kimball , Brevik Iver
Published: March 2018

It is known that the Casimir self-energy of a homogeneous dielectric ball is divergent, although a finite self-energy can be extracted through second order in the deviation of the permittivity from the vacuum value. The exception occurs when the speed of light inside the spherical boundary is the same as that outside, so the self-energy of a perfectly conducting spherical shell is finite, as is the energy of a dielectric-diamagnetic sphere with ε μ = 1 , a so-called isorefractive or diaphanous ball. Here we re-examine that example and attempt to extend it to an electromagnetic δ -function sphere, where the electric and magnetic couplings are equal and opposite. Unfortunately, although the energy expression is superficially ultraviolet finite, additional divergences appear that render it difficult to extract a meaningful result in general, but some limited results are presented.
Symmetries in Classical and Quantum Treatment of Einstein’s Cosmological Equations and Mini-Superspace Actions
Authors: Christodoulakis Theodosios , Karagiorgos Alexandros , Zampeli Adamantia
Published: March 2018

The use of automorphisms of the various Bianchi-type Lie algebras as Lie-point symmetries of the corresponding Einstein field equations entails a reduction of their order and ultimately leads to the entire solution space. When a valid reduced action principle exists, the symmetries of the configuration mini-supermetric space can also be used, in conjunction with the constraints, to provide local or non-local constants of motion. At the classical level, depending on their number, these integrals can even secure the acquisition of the entire solution space without any further solving of the dynamical equations. At the quantum level, their operator analogues can be used, along with the Wheeler–DeWitt equation, to define unique wave functions that exhibit singularity-free behavior at a semi-classical level.

Published: March 2018

Equally partitioned data are essential for prediction. However, in some important cases, the data distribution is severely unbalanced. In this study, several algorithms are utilized to maximize the learning accuracy when dealing with a highly unbalanced dataset. A linguistic algorithm is applied to evaluate the input and output relationship, namely Fuzzy c-Means (FCM), which is applied as a clustering algorithm for the majority class to balance the minority class data from about 3 million cases. Each cluster is used to train several artificial neural network (ANN) models. Different techniques are applied to generate an ensemble genetic fuzzy neuro model (EGFNM) in order to select the models. The first ensemble technique, the intra-cluster EGFNM, works by evaluating the best combination from all the models generated by each cluster. Another ensemble technique is the inter-cluster model EGFNM, which is based on selecting the best model from each cluster. The accuracy of these techniques is evaluated using the receiver operating characteristic (ROC) via its area under the curve (AUC). Results show that the AUC of the unbalanced data is 0.67974. The random cluster and best ANN single model have AUCs of 0.7177 and 0.72806, respectively. For the ensemble evaluations, the intra-cluster and the inter-cluster EGFNMs produce 0.7293 and 0.73038, respectively. In conclusion, this study achieved improved results by performing the EGFNM method compared with the unbalanced training. This study concludes that selecting several best models will produce a better result compared with all models combined.
Dispersion Forces Between Fields Confined to Half Spaces
Authors: Bordag M. , Pirozhenko I.G.
Published: March 2018

We consider the Casimir effect for a scalar field interacting with another scalar field that is confined to two half spaces. This model is aimed to mimic the interaction of the photon field with matter in two slabs. We use Dirichlet boundary conditions on the interfaces for the fields in the half spaces and calculate their one-loop contribution to the wave equation for the other field. We perform the ultraviolet renormalization and develop a convenient formalism for the calculation of the vacuum energy in this configuration.
Spiral Mobility Based on Optimized Clustering for Optimal Data Extraction in WSNs
Authors: Asad Muhammad , Nianmin Yao , Aslam Muhammad
Published: March 2018

Wireless Sensor Networks (WSNs) have led to tremendous growth in the development of sensor technology and offer numerous applications, such as wildlife monitoring, environment, healthcare, military surveillance and security systems. In terms of performance, the evolutions of WSN routing protocols play a vital role in extending the lifetime of networking operations. Due to the limited resources of power in sensor nodes, the design and implementation of an energy-efficient routing protocol comprise a key challenge for researchers. Before, in the case of a static sink, nodes at farther areas from the sink transmit their sensed data at a longer transmission range and die early, while nearby nodes face lesser transmission costs and stay alive for a longer period. This unbalanced energy distribution creates energy holes in ares far from the sink in WSNs. Mobility-based sink routing protocols are proposed to minimize the sub-optimal energy consumption in WSNs, as the sink mobility covers the sensor field, which alleviates the overall load-balancing among sensor nodes. In order to overcome the energy hole issue while prolonging the network lifetime, it is important to determine the optimal mobility pattern. In this regard, we propose the Spiral Mobility based on Optimized Clustering (SMOC) routing protocol and the Multiple sink-based SMOC (M-SMOC) routing protocol for large-scale WSNs. Performance evaluations of the proposed protocols are compared with various existing routing protocols based on static sink, random mobility and grid mobility. Different numbers of performance parameters are considered for evaluation, such as network lifetime, network stability, packet drop ratio, packet delivery ratio, end-to-end delay, average energy consumption, network connection time and the impact of different heterogeneity levels. Experimental results show the benefits of the spiral mobility pattern and how it improves the network lifetime and stability period over the existing state-of-the-art routing protocols.

The determination of zearalenone (ZEN) and its derivatives as biomarkers in animal tissues or organs plays an important role in mycotoxin monitoring and can promote effective exposure assessment. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the simultaneous quantification of nine ZEN-like mycotoxins, including three glucuronides in different pig tissues (heart, liver, spleen and muscle) was developed and validated in this study. Tissue samples were extracted using a quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction and clean-up procedure, and analyzed by LC-MS/MS in multiple reaction monitoring (MRM) mode. Dynamic linear ranges for each target analyte were determined with R2 between 0.916 and 0.999. The LODs of the six ZENs were achieved in the range of 0.5–1 ng/g and the LOQs varied from 1 ng/g to 2 ng/g. The satisfying intra-day and inter-day reproducibility (both RSDr and RSDR < 20%) indicated a good stability of this method. The recoveries of the nine target analytes were in the range of 70–110%. The validation results showed that this LC-MS/MS method coupled with QuEChERS sample pretreatment is effective and suitable for the simultaneous quantitation of ZEN metabolites in pigs. It has been applied to analysis of the pig tissues in this research and can be also adapted for samples in the mycotoxin research field.
The Integration of Socio-Economic Indicators in the CASBEE-UD Evaluation System: A Case Study
Authors: Cappai Francesco , Forgues Daniel , Glaus Mathias
Published: March 2018

The use of tools to measure the degree of sustainability of cities is the approach that receives the most attention in developed countries. However, studies of evaluation tools at the neighborhood level reveal that there are many weaknesses in the most widely-used evaluation systems (LEED-ND, BREEAM Communities, CASBEE-UD). There are ambiguities and gaps in weighting and in scoring and in most cases, there is no mechanism for local adaptability and participation. The purpose of this study is to provide an overview of the current situation by highlighting the strengths and weaknesses of these evaluation tools in order to integrate social and economic aspects for the improvement of the CASBEE-UD (neighborhood level) evaluation tool. The selection of socio-economic aspects was made through the use of a multi criteria Analysis Hierarchical Process (AHP) and a Geographic Integration System (GIS). The results of this case study indicate that most evaluation tools need to be revised because most do not include socio-economic aspects. We have demonstrated that applying the CASBEE-UD assessment tool integrated with socio-economic aspects to four boroughs in the City of Montreal can measure success by addressing the objectives of sustainable development.

Published: March 2018

The objective of this study was to compare the public perception in desert and rainy regions of Chile regarding the reuse of treated sewage water. The methodology of this study consisted of applying a survey to the communities of San Pedro de Atacama (desert region) and Hualqui (rainy region) to identify attitudes about the reuse of sewage water. The survey was applied directly to men and women, 18 to 90 years old, who were living in the studied communities. The results indicate that inhabitants of San Pedro de Atacama (desert region) were aware of the state of their water resources, with 86% being aware that there are water shortages during some part of the year. In contrast, only 55% of residents in Hualqui (rainy region) were aware of water shortages. With respect of the reuse of treated sewage water, 47% of respondents in San Pedro de Atacama understood the concept, as compared to 27% in Hualqui. There was more acceptance of using treated sewage water for non-potable purposes than as drinking water.
Hubble Parameter and Baryon Acoustic Oscillation Measurement Constraints on the Hubble Constant, the Deviation from the Spatially Flat ΛCDM Model, the Deceleration–Acceleration Transition Redshift, and Spatial Curvature
Authors: Yu Hai , Ratra Bharat , Wang Fa-Yin
Published: March 2018

We compile a complete collection of reliable Hubble parameter H(z) data to redshift z ≤ 2.36 and use them with the Gaussian Process method to determine continuous H(z) functions for various data subsets. From these continuous H(z)'s, summarizing across the data subsets considered, we find H
0 ∼ 67 ± 4 km s−1 Mpc−1, more consistent with the recent lower values determined using a variety of techniques. In most data subsets, we see a cosmological deceleration–acceleration transition at 2σ significance, with the data subsets transition redshifts varying over

at 1σ significance. We find that the flat-ΛCDM model is consistent with the H(z) data to a z of 1.5 to 2.0, depending on data subset considered, with 2σ deviations from flat-ΛCDM above this redshift range. Using the continuous H(z) with baryon acoustic oscillation distance-redshift observations, we constrain the current spatial curvature density parameter to be

, consistent with a flat universe, but the large error bar does not rule out small values of spatial curvature that are now under debate.
Cantharellus violaceovinosus, a new species from tropical Quercus forests in eastern Mexico
Authors: Herrera Mariana , Bandala Victor M. , Montoya Leticia
Published: March 2018

During explorations of tropical oak forests in central Veracruz (eastern Mexico), the authors discovered a Cantharellus species that produces basidiomes with strikingly violet pileus and a hymenium with yellow, raised gill-like folds. It is harvested locally and valued as a prized edible wild mushroom. Systematic multiyear sampling of basidiomes allowed the recording of the morphological variation exhibited by fresh fruit bodies in different growth stages, which supports the recognition of this Cantharellus species from others in the genus. Two molecular phylogenetic analyses based on a set of sequences of species of all major clades in Cantharellus, one including sequences of the transcription elongation factor 1-alpha (tef-1α) and a combined tef-1α and nLSU region (the large subunit of the ribosome), confirm the isolated position of the new species in a clade close to C.lewisii from USA, in the subgenus Cantharellus. Detailed macroscopic and microscopic descriptions, accompanied by illustrations and a taxonomic discussion are presented.
Is the Italian stream frog (Rana italica Dubois, 1987) an opportunistic exploiter of cave twilight zone?
Authors: Lunghi Enrico , Bruni Giacomo , Ficetola Francesco Gentile , Manenti Raoul
Published: March 2018

Studies on frogs exploiting subterranean environments are extremely scarce, as these Amphibians are usually considered accidental in these environments. However, according to recent studies, some anurans actively select subterranean environments on the basis of specific environmental features, and thus are able to inhabit these environments throughout the year. We present the first study on the abundance and spatial use of the Italian stream frog, Ranaitalica, in subterranean environments. We monthly collected data from 66 cave sectors during a whole year (2013), recording > 120 detections of R.italica. Frogs were more frequently found close to the cave entrance, without significant differences between age classes or sexes. Adults generally were observed being higher up along cave walls compared to juveniles. Frogs abundance was higher in areas showing specific environmental features, such as warm temperature, low incident light and the presence of potential prey. Ranaitalica likely occupies subterranean areas characterized by a combination of microclimatic suitability and prey availability.

Une frontière qualifiante : Représentation du passage en Perse chez quelques voyageurs français
Authors: Atlas Yasmine
Published: March 2018

Au xvii e  siècle, les « Francs » désireux de passer en Perse s’inscrivent, bon gré mal gré, dans un contexte géopolitique qui leur fait nettement sentir l’expérience de la frontière. S’ils sont généralement bienvenus sur les terres du Shah, ils doivent d’abord affronter la défiance des Ottomans, qui ont lieu de craindre une alliance à leur encontre. Aux récits de Jean-Baptiste Tavernier, Jean Thévenot et François de La-Boullaye-Le-Gouz correspondent trois manières bien distinctes de négocier l’entrée en Perse. Reste qu’invariablement, ce passage d’un régime viatique à l’autre apparaît comme un lieu privilégié de figuration de soi.
« Remarquer Ispahan » selon Thévenot : marques, remarques, contremarques et démarques persanes
Authors: Requemora-Gros Sylvie
Published: March 2018

La Suite du Voyage de Levant dans laquelle après plusieurs remarques très singulières […] il est traité de la Perse (1674), consacrée au voyage de Jean de Thévenot à Ispahan, est le fruit d’une recomposition posthume à quatre mains par le frère du voyageur, exécuteur testamentaire, et par un expert orientaliste. Un journal de notes éparses se trouve ainsi restructuré en chapitres mettant en avant des « remarques » qui sont à la fois marquage d’un lieu et d’un texte, démarquages par rapport aux textes de voyageurs antérieurs, pour finalement contremarquer à la fois le passage vers un monde bigarré et une méthode viatique tant scripturale qu’éditoriale, à la manière d’une marqueterie structurelle et symbolique.
Convivialité et connivence à Ispahan ? Jean-Baptiste Tavernier à la cour de Shah Abbas II
Authors: Barthe Pascale
Published: March 2018

Telle que Jean-Baptiste Tavernier la narre dans ses Voyages , sa visite à la cour de Shah Abbas à Ispahan au milieu des années 1660 aurait donné lieu à de longs échanges directs et festifs entre le marchand et son hôte. Cependant, derrière un décorum de convivialité incontestable, peut-il être question de connivence entre le Français et le Safavide ? L’analyse détaillée du récit de Tavernier est ici confrontée à la culture littéraire et artistique persane et suggère un rapport complexe entre les deux hommes, rapport à l’image des liens d’inter-impérialité qui unissent au XVII e  siècle Perse safavide, Inde moghole et royaume de France.
Comment peut-on être Français en Perse au xvii e  siècle ? Échanges interculturels, regards et contre-regards
Authors: Parlea Vanezia
Published: March 2018

Les relations des voyageurs français qui se rendent au xvii e  siècle dans la Perse safavide foisonnent de représentations de l’Autre plus ou moins hautes en couleur. Un aspect peu étudié, que cet article se propose d’aborder, est la manière dont ces récits construisent l’image des voyageurs eux-mêmes, à la croisée des regards français et des contre-regards persans. En prenant comme point de départ les expériences viatiques de Jean-Baptiste Tavernier et de Jean Chardin, l’analyse met en lumière les multiples facettes de la dynamique interculturelle mouvante et ambiguë qui se met en place entre Français et Persans au sein d’un univers profondément ambivalent.
La scène polémique des Mémoires : l’exemple de Guy Joly et du cardinal de Retz
Authors: Tribout Bruno
Published: March 2018

La critique a proposé de relire avec profit les Mémoires d’Ancien Régime comme des œuvres de combat. Dans cette perspective, on gagnerait à ne pas considérer les Mémoires isolément, mais à les restituer aux espaces polémiques qui les conditionnent. Nous adopterons cette approche pour éclairer les Mémoires de Joly dans leur rapport à ceux de Retz. Le pouvoir a voulu capter leur puissance polémique en suscitant leur publication (1718) pour contrer le succès remporté par l’œuvre de Retz (1717). Or cette instrumentalisation masque la véritable portée polémique du texte de Joly, qui noue un dialogue complexe avec celui du cardinal. Critique lorsque Retz néglige son combat contre Mazarin ou pour l’archevêché, Joly défend vigoureusement l’action politique du prélat, dont il construit une image cohérente au service d’une vision tempérée de la monarchie.

Le courant nord-américain de la « théologie publique » part de la reconnaissance du fait croissant du pluralisme religieux des sociétés actuelles et de la situation de post-sécularité à laquelle ce pluralisme nous amène. Développant une intuition première de l’historien Martin Marty, plusieurs auteurs ont proposé des systématisations de l’idée d’une théologie qui parle à la vie publique. La méthodologie la plus solide est probablement celle de David Tracy et sa corrélation critique mutuelle, spécialement telle qu’elle a été développée en théologie morale par David Hollenbach. Cette position peut se penser dans le cadre philosophique de l’herméneutique gadamérienne et la philosophie social-critique de Habermas. Les exemples d’application de cette théologie nous montrent sa valeur.
Les effets perturbateurs du désamour sur l’organisation de la séparation
Authors: Hippert Denis
Published: March 2018

Banalisation des séparations et du divorce, d’une part, dédramatisation des procédures, d’autre part, pourraient laisser penser que les désunions se déroulent désormais sans heurts et sans souffrance. Et pourtant, il est possible que l’organisation de la séparation se passe mal pour les conjoints et qu’ils divorcent par consentement mutuel. C’est ce décalage que nous proposons d’étudier en explorant les effets perturbateurs du désamour au cours d’une séquence particulière de la « carrière » relationnelle de certains couples : de la rupture conjugale jusqu’à la cessation de cohabitation. À partir d’une analyse d’une dizaine de cas issue d’une enquête par entretiens approfondis, menée auprès d’hommes et de femmes de milieux sociaux différents, séparés ou divorcés et en cours de séparation et de divorce, l’article montrera comment les états que provoque le désamour chez le conjoint aimant et chez le conjoint aimé sont susceptibles d’affecter la distribution des rôles parentaux, des avantages pratiques et matériels, des sentiments de sympathie et de loyauté générateurs de disponibilités et de solidarités.
Les effets de genre de la séparation sur l’endettement des hommes et des femmes en Suisse : une analyse longitudinale
Authors: Wernli Boris , Henchoz Caroline
Published: March 2018

Alors qu’en France comme en Suisse plus de 40 mariages sur 100 s’achèvent par un divorce, on en sait encore peu sur les conséquences d’une séparation sur l’endettement individuel. Cette étude longitudinale fondée sur les données du panel suisse de ménages rend compte des risques accrus d’endettement global pour les parents ainsi que pour les personnes qui conservent un lien de codépendance économique après la séparation. Elle relève les effets négatifs cumulés de la séparation pour les pères séparés qui obéissent au modèle familial et de rupture dominant. Elle souligne également les conséquences plus contrastées de la séparation sur l’endettement des femmes, certaines parvenant à entrer dans une logique d’émancipation financière en se libérant de leurs arriérés de paiement alors que d’autres gèrent leurs dettes au prix d’importantes difficultés économiques mais sans que cela n’affecte forcément leur niveau de satisfaction.
Les travailleurs sociaux, héritiers des ordres religieux prémodernes
Authors: Bosqué Clément
Published: March 2018

L’objectif de cette contribution est de fournir des éléments d’analyse de l’imaginaire du travail social dans le contexte de la postmodernité. Prenant en compte l’histoire, l’arrière-plan théorique et la formation des travailleurs sociaux, cet article fait l’hypothèse que tout en revendiquant des notions typiquement modernes telles que l’analyse rationnelle, l’autonomie, le projet, les travailleurs sociaux peuvent être vus comme les héritiers de formes sociales prémodernes, en particulier les ordres et corporations religieux.
Vertu et vice de la combinaison du contrôle et du désir. Le body-building et le capitalisme post-industriel
Authors: Kinnunen Taina , Vallet Guillaume
Published: March 2018

Cet article se focalise sur le bodybuilding considéré comme un sport extrême, au sens où il repose sur la logique de toujours repousser les résultats corporels acquis, donc les frontières du corps. En conséquence, en combinant les approches des organization studies , de l’anthropologie culturelle et des études féministes relatives à l’étude du corps dans un contexte socio-économique, nous effectuons un lien entre le bodybuilding et le capitalisme post-industriel, dans la mesure où ce dernier repose notamment sur une économie du contrôle et du désir. Dans le cadre de la pratique du bodybuilding, nous mettons en évidence que la relation au corps oscille en permanence entre ces deux pôles, mettant en jeu le rapport individuel à la santé (physique, mentale et sociale). Cette relation implique plus largement un entrepreneuriat de soi et la mise en œuvre d’un nouveau corps du travail, qui induit un management personnel des risques. Le bodybuilding est alors loin de correspondre à sa réputation de sous-culture curieuse ; il est au contraire fortement attractif pour quelqu’un souhaitant maximiser sa compétitivité corporelle dans les sociétés capitalistes post-industrielles.
La catastrophe écologique de Tchernobyl : les régimes de fausseté de l’information
Authors: Ambroise-Rendu Anne-Claude
Published: March 2018

Le traitement médiatique de la catastrophe survenue le 28 avril 1986 dans la centrale nucléaire de Tchernobyl en Ukraine a conjugué toutes les modalités de la fausse information. Soumis à un impératif de factualité qui laisse peu d’espace à l’indécision et à l’indécidable, les médias ont rendu compte de l’accident et de ses suites comme ils ont pu. Certes, la fable du nuage qui aurait épargné la France, specimen de ce “canard” que les journaux du xix e siècle dénonçaient, a été assez rapidement mise à mal, cristallisant les débats et devenant un sujet à part entière : celui de la manière dont la fausse information peut se propager. Mais factualité n’est pas vérité et quand la première s’avère insaisissable, la seconde devient généralement polémique. Il en fut ainsi de la question des dommages sanitaires engendrés par le passage du fameux nuage, restée objet de polémiques jusqu’à ce jour. Cet article reprend le dossier en s’interrogeant sur les régimes de fausseté qui ont servi de cadre à ce long feuilleton : la fausseté due à l’absence d’information, la fausseté par rétention d’information, la fausseté relevant de diverses manipulations, la fausseté dépendant d’une défaillance épistémique, enfin. En prenant en compte la difficulté qu’il y avait pour les journalistes à traiter un sujet à la fois aussi technique et aussi « explosif. Si de fausses informations ont été diffusées par les médias, elles tiennent moins aux insuffisances des professionnels qu’à une convergence de facteurs parmi lesquelles on notera la réticence des « experts » à partager avec les journalistes et le public des informations jugées embarrassantes et/ou fauteuses de trouble, et la rétention des politiques soucieux de ne pas entamer le crédit de l’industrie nucléaire. Cette pratique largement dénoncée dès le 8 mai 1986, appartient à la logique de ce « gouvernement par le secret (qui caractérise) le pays le plus nucléarisé au monde ». Mais c’est aux journalistes qu’il revient d’avoir finalement fourni au public l’accès à l’information, recomposant de la sorte un espace public démocratique qui se trouvait de fait menacé par la rétention des autorités.
‘Conditional’ Citizens? Hawkers in the Streets (and the Courts) of Contemporary India
Authors: Joshi Kunal
Published: March 2018

Street vendors have often been seen as archetypal examples of informality in cities—constituting what Chatterjee (2004), for instance, has called political society—indispensable to the city, but continually having to negotiate the law, their claims to citizenship perpetually tenuous. Using Chatterjee’s framework as a guide, I look at how the movement for street vendors’ rights has evolved in India over the last few decades. I have studied the legal as well as political struggle waged by various street vendors’ groups over the last decade, which eventually culminated in a national law legalizing street vending in India in 2014. That this law was passed amid increasingly strong aspirations for (hawker-free) 'world-class' cities on the part of the middle class is in itself significant, but shows, more importantly, how the Indian street vendor, far from seeking exceptions to the law, is increasingly demanding to be let in to the governmental gaze of the state. Although there have been many problems with the implementation of the bill since its passage, I argue that by institutionalizing a right to vend, the campaign which led to the bill has created new possibilities for vendors to negotiate with the state at all levels.

The Influence of the Bush-Bushes Pocket Geometry on the Bush Contact Angle
Authors: Velicu Radu , Saulescu Radu , Lates Mihai Tiberiu
Published: March 2018

The chain drive transmissions are used mainly in the automotive industry as distribution transmissions in cars. In the specific literature, the kinematics and the dynamic analysis problems are accomplished depending on the European and American standards. The contact between the chain’s bush and the chain wheel is influencing the transmissions dynamics and is influenced directly by its geometry. According to these, the paper presents the influence of the chain wheel’s geometry on the contact angle which depends on the point’s position where the normal and transversal forces are acting.
An Experimental Study Regarding the Vibratory Behaviour for Some Textile Composites
Authors: Tărâţă Daniela Florentina , Miriţoiu Cosmin Mihai
Published: March 2018

The paper presents the results of our research in the elaboration and characterization of composites type epoxy - textile fiber and vibration behaviour. These were made by pressing, and the textile fibers we tested were cotton, flax, hemp and wool. Starting from the dynamic response of composite beam with damping (which is in free vibration), there is established a way to determine the damping factor. There has been experimentally determined the damping factors for some samples: sample 1 – built from cotton; sample 2 – built from hemp; sample 3 – built from flax; sample 4 – built from whool.
Validation of GenEcAm Software Results in Simulation of Seismic Behavior of Buildings Equipped with Damping System
Authors: Ionescu Adriana , Negru Mihai , Burada Cristian Oliviu , Malciu Raluca
Published: March 2018

This paper presents the validation process of the GenEcAm program made by the author by comparing the results obtained with this program with the results obtained with the SAP2000 program at the dynamic analysis of a P+10E building equipped with viscous fluid dampers, one on each facade on each level. The results obtained with these two programs are very close, which validates the correctness of the analytical and computational model that underpinned the creation of the GenEcAm program. The GenEcAm program allows the use of 9 theoretical models of hysteresis to simulate seismic behavior of the dampers that equippe the structure of a building.
