Foreign Direct Investment and the Pollution Haven Hypothesis in Indonesia
Authors: Shofwan Shofwan , Fong Michelle
Published: December 2014

This paper investigates the validity of the pollution haven hypothesis in the context of Foreign Direct Investment (FDI) in Indonesia by determining the correlations between carbon emission and foreign direct investment, gross domestic product, and population size between 1975 and 2009 in that country. Statistical results from Spearman‟s correlation analysis show that CO2 emission has a statistically significant negative relationship with real Gross Domestic Product (GDP), and a statistically significant positive relationship with population size in the Indonesian economy between 1975 and 2009. However, there is a weak and insignificant relationship between CO2 emission and real FDI during this period which indicates weak support for the pollution haven hypothesis because FDI does not appear to be as strong a contributing factor to CO2 emission as the activities of the population in Indonesia.

Published: December 2014

The aim of this study was to examine whether the antioxidant alpha-lipoic acid protects neurons from diabetic-reperfusion injury. The streptozotocin (STZ) rat model was used to study the glial reactivity and prevention of gliosis by alpha-lipoic acid (alpha-LA) administration. The expression of glial fibrillary acidic protein (GFAP) was determined, as well as lipid peroxidation (LPO) and glu-tathione (GSH) levels in some brain tissues. We observed significant increasing of lipid peroxidation products in both hippocampus and cortex. Changesof polypeptide GFAP were observed in hippocampus and cortex. Both soluble and filamentous forms of GFAP featured the increase in hippocampus of rat with hyperthyreosis. In the filamentfractions, increase in the intensity of 49 kDa polypeptide band was found. In the same fraction of insoluble cytoskeleton proteins degraded HFKB polypeptides with molecular weight in the range of 46–41 kDa appeared. Markedincrease of degraded polypeptides was found in the soluble fraction of the brain stem. The intensity of the intact polypeptide – 49 kDa, as well as in the filament fraction, significantly increased. It is possible that increasing concentrations of soluble subunits glial filaments may be due to dissociation of own filaments during the reorganization of cytoskeleton structures. Given the results of Western blotting for filament fraction, increased content of soluble intact 49 kDa polypeptide is primarily the result of increased expression of HFKB and only partly due to redistribution of existing filament structures. Calculation and analysis of indicators showed high correlation between the increase in content and peroxidation products of HFKB.These results indicate the important role of oxidative stress in the induction of astroglial response under conditions of diabet encefalopathia. Administration of alpha-LA reduced the expression both of glial and neuronal markers. In addition, alpha-LA significantly prevented the increase in LPO levels found in diabetic rats. GSH levels increased by the administration of alpha-LA. This study suggests that alpha-LA prevents neural injury by inhibiting oxidative stress and suppressing reactive gliosis. All these changes were clearly counteracted by alpha-lipoic acid. The results of this study demonstrate that alpha-lipoic acid provides for protection to the GFAP, as a whole, from diabet -reperfusion injuries.

Published: December 2014

Cocinas and San Pancho Islands, located in the Bay of Chamela, Jalisco, México, are two of the few remaining island ecosystems with little ecological disturbance. We studied both islands aiming to assess their reptile richness. Because the environment in Chamela is seasonal, we conducted biodiversity surveys during six samplings: three in the dry season and three in rainy season. We found a total of seven reptile species on Cocinas and San Pancho Islands representing the first description of their herpetofauna. We recorded four species (Aspidoscelis lineattissima, Hemidactylus frenatus, Iguana iguana, and Urosaurus bicarinatus) on Cocinas Island, and six species (A. lineattissima, Phyllodactylus lanei, H. frenatus, Anolis nebulosus, Urosaurus bicarinatus, and Boa constrictor) on San Pancho Island. Species richness in Cocinas showed a higher evenness than in San Pancho Island. Finally, A. lineattissima and A. nebulosus were the dominant species on Cocinas and San Pancho Islands, respectively.

Authors: Cavalcanti Juliana Manzoni , Maio Marcos Chor
Published: December 2014

Aborda os estudos médicos e científicos sobre a anemia falciforme publicados no Brasil nas décadas de 1930 e 1940. A miscigenação foi apontada, pela maioria dos médicos e cientistas, como interferência significativa na epidemiologia da doença no país. Destaca a atuação do hematologista do Instituto Oswaldo Cruz Ernani Martins da Silva, que efetuou análises sanguíneas no interior no Brasil para determinar os grupos populacionais miscigenados e puros, baseado na identificação de hemácias falciformes e da distribuição racial dos grupos sanguíneos. Analisam-se as ambivalências existentes na associação entre a anemia falciforme e 'raça negra' durante os anos de 1930 e 1940 no Brasil.
Malaria epidemics in Europe after the First World War: the early stages of an international approach to the control of the disease
Authors: Gachelin Gabriel , Opinel Annick
Published: December 2014

The severity and endemicity of malaria declined gradually in Europe until WWI. During and after the war, the number of malaria cases increased substantially and peaked in 1922-1924. This prompted the Hygiene Commission of the League of Nations to establish a Malaria Commission in 1923 to define the most efficient anti-malaria procedures. Additionally, between 1924 and 1930 there were several international meetings and collaborations concerning malaria, which involved the main institutes of parasitology and the Rockefeller Foundation. The Commission reports, the guidelines for anti-malaria campaigns and the scientific programs which came out of these meetings and collaborations are analyzed in the present paper.

Analisa as relações entre doenças, conhecimento e ocupação do território na Comissão de Linhas Telegráficas Estratégicas de Mato Grosso ao Amazonas, mais conhecida como Comissão Rondon. A Comissão, entre 1907 e 1915, atravessou de sul a norte amplas regiões do que são hoje os estados de Mato Grosso, Rondônia e Amazonas, na faina de instalar linha telegráfica que seria responsável pela integração dessas regiões às principais cidades brasileiras. Ao longo do tempo, a malária, doença endêmica nas localidades percorridas, forçou a Comissão a abrir mão de alguns objetivos e a retardar a realização de outros. O impacto dessa doença nos trabalhos da Comissão, com destaque para a criação de um serviço sanitário primordialmente destinado a seu controle, é o foco deste artigo.
The bitumen microstructure: a fluorescent approach
Authors: Handle Florian , Füssl Josef , Neudl Susanna , Grossegger Daniel , Eberhardsteiner Lukas , Hofko Bernhard , Hospodka Markus , Blab Ronald , Grothe Hinrich
Published: December 2014

Five bituminous samples were carefully studied by confocal laser scanning microscopy using 488 nm excitation radiation and observing 500–530 nm of emission. The images revealed the microstructure of bitumen. The influence of the admixture of mineral aggregates concerning the microstructure was tested. For the minerals, no significant influence was found. For understanding the origin of fluorescent signals, the samples were separated into asphaltenes and maltenes and analyzed with fluorescence spectroscopy. Although former works have assumed the origin of fluorescent emissions in bitumen to be found in the asphaltene fraction, the asphaltenes produce little to no emissions, but the maltenes exhibit strong fluorescence in the observed spectral region. For deeper insight, fractionation of the bitumina into the SARA fractions by chromatographic column separation was necessary. The fluorescence spectra of these fractions were analyzed and revealed the aromatics and resin phases to be the only components capable of sufficiently intense fluorescent emission. This is a strong argument for a complex internal microstructure consisting of a mantle of aromatics surrounding an inner core.

Authors: Borş Andreea , Molnar-Varlam Cristina , Székely Melinda
Published: December 2014

Objective: The aim of this in vitro study was to evaluate the influence of erosive conditions on the wear resistance of aesthetic direct restorative materials. Methods: Six dental filling materials were tested: two composites (Filtek Z550 and X-tra fil), two compomers (Dyract Extra and Twinky Star) and two glass ionomers (Ketac Molar and Fuji II LC). Twenty disks (10mm×2mm) of each material were prepared (n=120) and kept in artificial saliva at 37˚C for 24 hours. Specimens were cycled in acidic soft drink (Coca-Cola) 5×/day, for 5’, over 30 days. Initial surface roughness ISR (Ra-μm) and final surface roughness FSR were measured using a profilometer. The wear rate was calculated as difference of final minus the initial roughness (ΔSR=FSR-ISR). For statistical analysis t-test and one-way ANOVA test were used by GraphPad Prism version 5.03 statistical software. The level of significance was set at p<0.05. Results: The erosive wear rates (mean±SD, μm) after exposure to acidic beverage were: 0.30±0.03 (Ketac Molar), 0.28±0.04 (Fuji II LC), 0.27±0.00 (Filtek Z550), 0.23±0.01 (X-tra fil), 0.20±0.00 (Twinky Star) and 0.14±0.01 Dyract Extra, respectively. There were significant differences between the tested materials (p<0.05). Conclusions: Dental filling materials had different behaviour under the same erosive condition, however all investigated aesthetic restorative materials showed surface degradation. These findings suggest that erosive wear resistance of tooth coloured restoratives could influence their longevity in intraoral acidic conditions.

Published: December 2014

Cerebral venous thrombosis (CVT) represents 1% of the total stroke pathology but is a real challenge both regarding the diagnosis and the treatment.

Objective: Evaluate different etiological, demographical, clinical, imaging and therapeutic aspects of CVT. Material: Prospective study during 4 years. From the total 3658 patients hospitalized with acute stroke, 45 (1.23%) had CVT. For each patient, were recorded: demographic data, symptom of onset, type of onset, daily habits, medical history, neurological examination, brain imaging (CT and MRI with venography). Statistical analysis: data are presented as mean and SD and Student t test was applied.

Results: Mean age was 44.07± 23,12 years; female: male ratio 2.21:1. The most frequent type of onset was acute (77.78%). Headache was found in 80% of cases as initial symptom, followed by neurological focal deficits. As risk factors, thrombophilia was found most often (59.5%), followed by local infections. No risk factors were found in 17.8% of cases. The brain imaging was positive in 29 patients. In 16 cases, the imaging workout was negative and the diagnosis consisted of clinical criteria, risk factors, response to heparin treatment.

Conclusions: CVT is a rare pathology that affects mainly young women and that needs a complex diagnostic evaluation. The patient prototype diagnosed with CVT in our region: female of 44 years old, with an intense acute headache, with MRI showing direct signs of transverse sinus thrombosis, with a thrombophilic state and good response to anticoagulants. Brain MRI is the imaging investigation required but clinical aspects play a decisive role.
Cephalic Duodeno-Pancreatectomy with Pancreatic-Gastric Anastomosis with Double Purse String, in Patient with Lithiasis and Tumoral Jaundice - Case Report
Authors: Tudor A , Molnar C , Nicolescu C , Rosca C , Tudor Bianca , Tudor V.O , Copotoiu C
Published: December 2014

Introduction: One of the most feared complications after cephalic duodeno-pancreatectomy remains pancreatic fistula. In recent years, various methods of pancreatico-digestive reconstruction were performed in order to reduce the rate of pancreatic fistula. One of these methods is pancreatico-gastric reconstruction by using two purse string threads.

Case report: We present in this article a patient with jaundice with mixed etiology: tumoral and lithiasic. Subjectively, the patient accused sclerose-skin-jaundice, right upper quadrant and epigastric pain, nausea and vomiting. Computed tomography revealed dilatation of intraand extrahepatic bile ducts, a dilated Wirsung duct and a tumor at the biliopancreatic confluence, leading to a suspicion of vaterian ampulom. Upper endoscopy revealed a tumor protruding in the descending duodenal segment. Intraoperatively a tumor suggestive of vaterian ampulom and duct stones was shown. Surgical treatment consisted of coledocolitotomy, cephalic duodeno-pancreatectomy with pancreatic-gastric anastomosis, performed by using two purse string threads. The postoperative evolution was favorable.

Conclusion: Pancreatico-gastric anastomosis using two purse string threads is a simple, safe and quick procedure, avoiding the application of sutures through the pancreatic parenchyma and thus reducing the rate of pancreatic fistula.

Authors: Barlak M. , Chmielewski M. , Werner Z. , Pietrzak K.
Published: December 2014

Commercial Inconel 600 nickel-chromium alloy was implanted with nitrogen, titanium, chromium, copper with tin (as bronze components) and yttrium ions to doses ranging from 1.6e17 to 3.5e17 cm−2. The aim of this research was to investigate the properties of the modified alloy in the context of its application in foil bearings. The virgin and the treated samples were tribologically tested and examined by Scanning Electron Microscopy, Glow Discharge Mass Spectrometry and Energy Dispersive Spectroscopy. The technological studies were preceded by modelling of concentration values of the introduced elements. The results obtained with the use of ion implantation are discussed. There are two advantages which should be highlighted: good agreement in modelling and experimental results of depth profiles of implanted ions, wear resistance improvement of Inconel 600 surface by implantation of copper and tin ions. The tribological tests indicate that abrasion and corrosion are the predominant mechanisms of surface wear.
A Case Study on the Phylogeny and Conservation of Saker Falcon
Authors: Pomichal Krisztián , Vági Balázs , Csörgő Tibor
Published: December 2014

The Saker Falcon is a falconid raptor species with Palearctic distribution. It has never been a common bird in Hungary, now there are cc. 220-230 nesting pairs within the country borders. Currently total world population is cc. 19 000-34 000 individuals. Its taxonomic status is complicated. Two subspecies are distinguished (Falco c. cherrug and Falco c. milvipes); however, molecular data does not support this split. Phylogeny of the species is also not clarified, similarly to closely related raptors. There are many factors threatening the population of the Saker. One of these factors is the occurrence of the hybrid falcons. By molecular investigations more data can be gained, that could be useful in practical conservation, too.

Published: December 2014

The aim of the present study was to determine the influence of orally administered insecticide bendiocarb on the structure and ultrastructure of the kidney parenchyma in rabbits. Bendiocarb in the form of capsules (96% Bendiocarb, Bayer), at a dose of 5 mg/kg of body weight was fed daily for 3 days. After sampling, kidney sections of experimental and control animals were evaluated. Under a light and electron microscope the diffuse degenerative changes in kidney cortex and medulla were noted. Light microscopy revealed that the renal corpuscles had normal structure, but other nephron components and the collecting ducts were invariably changed. The epithelial cells inside the proximal and distal tubules and collecting ducts possessed increased quantity of cytoplasmic vacuoles and some tubular sections showed cellular sloughing and necrotization. The cells within the thin limbs of the Henley’s loops had normal histological structure except for sporadic necrotizing cells within some segments. The ultrastructural evaluation showed extensive cytoplasmic vacuolisation and degenerative changes, such as mitochondrial swelling and shortening of basal infoldings within proximal and distal tubules, and microvilli reduction within proximal tubules. Cells of the collecting tubules exhibited a higher number of vacuoles and some cells had apparently reduced organelles. The cells of the thin limbs of the Henle’s loop showed more vacuolised cytoplasm, some tubular sections revealed cellular detachment between the adjacent epithelial cells and rare necrotising epithelial cells were observed. The described findings addressed in the present study indicate an adverse effect of bendiocarb on the kidney parenchyma in rabbits.
Assessing Treatment-Resistant Posttraumatic Stress Disorder: The Emory Treatment Resistance Interview for PTSD (E-TRIP)
Authors: Dunlop Boadie , Kaye Joanna , Youngner Cole , Rothbaum Barbara
Published: December 2014

Patients with posttraumatic stress disorder (PTSD) who fail to respond to established treatments are at risk for chronic disability and distress. Although treatment-resistant PTSD (TR-PTSD) is a common clinical problem, there is currently no standard method for evaluating previous treatment outcomes. Development of a tool that could quantify the degree of resistance to previously provided treatments would inform research in patients with PTSD. We conducted a systematic review of PTSD treatment trials to identify medication and psychotherapy interventions proven to be efficacious for PTSD. We then developed a semi-structured clinician interview called the Emory Treatment Resistance Interview for PTSD (E-TRIP). The E-TRIP includes clinician-administered questions to assess the adequacy and benefit derived from past treatment trials. For each adequately delivered treatment to which the patient failed to respond, a score is assigned depending on the strength of evidence supporting the treatment’s efficacy. The E-TRIP provides a comprehensive assessment of prior PTSD treatments that should prove valuable for researchers studying TR-PTSD and evaluating the efficacy of new treatments for patients with PTSD. The E-TRIP is not intended to guide treatment; rather, the tool quantifies the level of treatment resistance in patients with PTSD in order to standardize TR-PTSD in the research domain.

Published: December 2014

Background: Lead is a pervasive pollutant, associated at low levels to many adverse health effects. Objective: To investigate lead levels, exposure pathways and intervention possibilities in school children from Alpuyeca, in Morelos, Mexico. Methods: Blood lead concentrations (BPb) were measured in 226 children in 2011. Exposure pathways were assessed through a questionnaire, lead measurements in different environmental matrices and spatial aggregation analysis of lead concentrations. Results: BPb ranged from 1.5 to 36.5 µg/dL, with a mean (SD) of 7.23 (4.9) µg/dL. Sixty-four and 18% of the children had BPb > 5 µg/dL and > 10 µg/dL, respectively. The use of lead glazed ceramics was reported in almost half of the households; it was the main BPb determinant and it was associated with an increased risk of having BPb > 5 g/dL by 2.7 times (p = 0.001). Environmental samples were within US EPA’s lead recommended limits, and blood lead levels were randomly distributed in the community. Conclusions: Lead remains a public health problem in Alpuyeca, Mexico. Unlike other local pollutants, lead exposure prevention can be achieved inexpensively and in a short term. Interventions should make mothers aware of lead’s health effects and empower them to safeguard their children’s health by avoiding the culturally ingrained use of lead glazed pottery.
Coordination Nature of 4-Mercaptoaniline to Sn(II) Ion: Formation of a One Dimensional Coordination Polymer and Its Decomposition to a Mono Nuclear Sn(IV) Complex
Authors: Burkett Eon , Siddiquee Tasneem
Published: December 2014

The coordination of the bifunctional ligand 4-mercaptoaniline with aqueo us tin(II) metal ion was studied. A coordination polymer was synthesized when an aqueous solution of SnCl2 was treated with 4-MA. The crystalline material is stable under atmospheric conditions retaining its oxidation state. However, when submerged in a solution saturated with oxygen, the compound oxidizes to a mononuclear tin(IV) complex. Both the compounds were characterized by single crystal X-ray diffraction studies. Although the structure of the tin(IV) complex was previously reported, crystal structure of this compound was redetermined.
The Fire Resistance Performance of Recycled Aggregate Concrete Columns with Different Concrete Compressive Strengths
Authors: Dong Hongying , Cao Wanlin , Bian Jianhui , Zhang Jianwei
Published: December 2014

In order to ascertain the fire resistance performance of recycled aggregate concrete (RAC) components with different concrete compressive strengths, four full-scaled concrete columns were designed and tested under high temperature. Two of the four specimens were constructed by normal concrete with compressive strength ratings of C20 and C30, respectively, while the others were made from recycled coarse aggregate (RCA) concrete of C30 and C40, respectively. Identical constant axial forces were applied to specimens while being subjected to simulated building fire conditions in a laboratory furnace. Several parameters from the experimental results were comparatively analyzed, including the temperature change, vertical displacement, lateral deflection, fire endurance, and failure characteristics of specimens. The temperature field of specimens was simulated with ABAQUS Software (ABAQUS Inc., Provindence, RI, USA) and the results agreed quite well with those from the experiments. Results show that the rate of heat transfer from the surface to the interior of the column increases with the increase of the concrete’s compressive strength for both RAC columns and normal concrete columns. Under the same initial axial force ratio, for columns with the same cross section, those with lower concrete compressive strengths demonstrate better fire resistance performance. The fire resistance performance of RAC columns is better than that of normal concrete columns, with the same concrete compressive strength.
Estimating the Energy State of Liquids
Authors: Wang Lianwen
Published: December 2014

In contrast to the gaseous and the solid states, the liquid state does not have a simple model that could be developed into a quantitative theory. A central issue in the understanding of liquids is to estimate the energy state of liquids. Here, on the basis of our recent studies on crystal melting, we show that the energy sate of liquids may be reasonably approximated by the energy and volume of a vacancy. Consequently, estimation of the liquid state energy is significantly simplified comparing with previous methods that inevitably invoke many-body interactions. Accordingly, a possible equation for the state for liquids is proposed. On this basis, it seems that a simple model for liquids is in sight.
Proton Adsorption Selectivity of Zeolites in Aqueous Media: Effect of Si/Al Ratio of Zeolites
Authors: Munthali Moses , Elsheikh Mohammed , Johan Erni , Matsue Naoto
Published: December 2014

In addition to their well-known uses as catalysts, zeolites are utilized to adsorb and remove various cations from aqueous system. The adsorption of the cations is ascribed to the negative charge of zeolites derived from isomorphous substitution of Si by Al. The amount of Na+ adsorption on 4A, X, Y, Na-P1 and mordenite type zeolites were determined in aqueous media, in a two-cation (Na+ and H+) system. Although each zeolite has a constant amount of negative charge, the amount of Na+ adsorption of each zeolite decreased drastically at low pH−pNa values, where pH−pNa is equal to log{(Na+)/(H+)}. By using the plot of the amount of Na+ adsorption versus pH−pNa, an index of the H+ selectivity, which is similar to the pKa of acids, of each zeolite was estimated, and the index tended to increase with decreasing Si/Al ratio of zeolites. These indicate that zeolites with lower Si/Al and higher negative charge density have higher H+ adsorption selectivity, and in fact, such a zeolite species (4A and X) adsorbed considerable amount of H+ even at weakly alkaline pH region. The adsorption of H+ results in the decrease of cation adsorption ability, and may lead to the dissolution of zeolites in aqueous media.
Nrf2-Mediated HO-1 Induction Contributes to Antioxidant Capacity of a Schisandrae Fructus Ethanol Extract in C2C12 Myoblasts
Authors: Kang Ji , Han Min , Kim Gi-Young , Kim Cheol , Kim Byung , Hwang Hye , Choi Yung
Published: December 2014

This study was designed to confirm the protective effect of Schisandrae Fructus, which are the dried fruits of Schisandra chinensis (Turcz.) Baill, against oxidative stress-induced cellular damage and to elucidate the underlying mechanisms in C2C12 myoblasts. Preincubating C2C12 cells with a Schisandrae Fructus ethanol extract (SFEE) significantly attenuated hydrogen peroxide (H2O2)-induced inhibition of growth and induced scavenging activity against intracellular reactive oxygen species (ROS) induced by H2O2. SFEE also inhibited comet tail formation and phospho-histone γH2A.X expression, suggesting that it prevents H2O2-induced cellular DNA damage. Furthermore, treating C2C12 cells with SFEE significantly induced heme oxygenase-1 (HO-1) and phosphorylation of nuclear factor-erythroid 2 related factor 2 (Nrf2). However, zinc protoporphyrin IX, a potent inhibitor of HO-1 activity, significantly reversed the protective effects of SFEE against H2O2-induced growth inhibition and ROS generation in C2C12 cells. Additional experiments revealed that the potential of the SFEE to induce HO-1 expression and protect against H2O2-mediated cellular damage was abrogated by transient transfection with Nrf2-specific small interfering RNA, suggesting that the SFEE protected C2C12 cells against oxidative stress-induced injury through the Nrf2/HO-1 pathway.

Published: December 2014

Although remote sensing technology has long been used in wetland inventory and monitoring, the accuracy and detail level of wetland maps derived with moderate resolution imagery and traditional techniques have been limited and often unsatisfactory. We explored and evaluated the utility of a newly launched high-resolution, eight-band satellite system (Worldview-2; WV2) for identifying and classifying freshwater deltaic wetland vegetation and aquatic habitats in the Selenga River Delta of Lake Baikal, Russia, using a hybrid approach and a novel application of Indicator Species Analysis (ISA). We achieved an overall classification accuracy of 86.5% (Kappa coefficient: 0.85) for 22 classes of aquatic and wetland habitats and found that additional metrics, such as the Normalized Difference Vegetation Index and image texture, were valuable for improving the overall classification accuracy and particularly for discriminating among certain habitat classes. Our analysis demonstrated that including WV2’s four spectral bands from parts of the spectrum less commonly used in remote sensing analyses, along with the more traditional bandwidths, contributed to the increase in the overall classification accuracy by ~4% overall, but with considerable increases in our ability to discriminate certain communities. The coastal band improved differentiating open water and aquatic (i.e., vegetated) habitats, and the yellow, red-edge, and near-infrared 2 bands improved discrimination among different vegetated aquatic and terrestrial habitats. The use of ISA provided statistical rigor in developing associations between spectral classes and field-based data. Our analyses demonstrated the utility of a hybrid approach and the benefit of additional bands and metrics in providing the first spatially explicit mapping of a large and heterogeneous wetland system.
Comparison of Global Navigation Satellite System Devices on Speed Tracking in Road (Tran)SPORT Applications
Authors: Supej Matej , Čuk Ivan
Published: December 2014

Global Navigation Satellite Systems (GNSS) are, in addition to being most widely used vehicle navigation method, becoming popular in sport-related tests. There is a lack of knowledge regarding tracking speed using GNSS, therefore the aims of this study were to examine under dynamic conditions: (1) how accurate technologically different GNSS measure speed and (2) how large is latency in speed measurements in real time applications. Five GNSSs were tested. They were fixed to a car’s roof-rack: a smart phone, a wrist watch, a handheld device, a professional system for testing vehicles and a high-end Real Time Kinematics (RTK) GNSS. The speed data were recorded and analyzed during rapid acceleration and deceleration as well as at steady speed. The study produced four main findings. Higher frequency and high quality GNSS receivers track speed at least at comparable accuracy to a vehicle speedometer. All GNSS systems measured maximum speed and movement at a constant speed well. Acceleration and deceleration have different level of error at different speeds. Low cost GNSS receivers operating at 1 Hz sampling rate had high latency (up to 2.16 s) and are not appropriate for tracking speed in real time, especially during dynamic movements.
Rehabilitation Priority Determination of Water Pipes Based on Hydraulic Importance
Authors: Yoo Do , Kang Doosun , Jun Hwandon , Kim Joong
Published: December 2014

This paper describes a study conducted to develop a method to facilitate more reliable determination of the rehabilitation priority order for water pipes by taking into account the pipes’ hydraulic importance. Existing methods use only the pipeline deterioration rate to determine the rehabilitation priority order. Accordingly, the deterioration rate under normal conditions and the hydraulic importance under abnormal conditions of water distribution pipelines were classified according to two different attributes. The deterioration rate of a water distribution pipeline was calculated in terms of the deterioration rate due to pipeline information factors and the deterioration rate resulting from the installation environment/external factors. The hydraulic importance of water distribution pipelines was calculated by considering the importance of a single pipe failure caused by water leakage or an accident and that of a multiple pipe failure caused by a disaster, such as an earthquake. These four attribute factors were employed in a multi-criteria decision-making process called a weighted utopian approach, developed in this study, that determines the final rehabilitation priority order for each pipeline. The study results indicate that the rehabilitation priority order can be determined more easily using this approach than with previously-developed methods and that the model developed is easier and more convenient to apply than existing rehabilitation priority order models that require a large amount of data, as well as complex failure probabilities and mathematical models.

Published: December 2014

Currently, debates on the performance of maintenance services in multi-storey public housing have been matters of great concern. Previous studies have proven that a close relationship between the residents and the management team is vital to enhance the performance of maintenance services, but limited studies have been geared towards the influence of communication on the performance of maintenance services. This study aims to examine the influence of communication between the residents and the management team on the performance of the maintenance services. A survey was conducted with the residents of multi-storey public housing in Penang, Malaysia, who were selected using stratified random sampling. A descriptive analysis, Pearson product-moment correlation, and multiple regression analysis were used to analyse the data. The results show that there is a significant and positive relationship between effective communication and the residents’ perceived performance of maintenance services. Two communication attributes, “satisfaction with the feedback” and “accuracy of information”, are the determinants for the performance of maintenance services.
Edward W. Said lecteur de Raymond Schwab
Authors: Moussa Sarga
Published: December 2014

Cet article part du constat qu’Edward Said, tout en ayant lu La Renaissance orientale (1950) de Raymond Schwab au moment où il préparait Orientalism (1978), n’y a pas accordé l’importance que méritait cette somme. Sans doute a-t-il dû la considérer comme une pierre dans son jardin, dans la mesure où la démarche profondément interculturelle du premier s’intègre mal à la théorie du « discours orientaliste ». D’où la volonté, chez l’auteur de L’Orientalisme , de se démarquer autant que possible, dans un premier temps, de La Renaissance orientale. Mais tout se passe comme si, une fois son ouvrage majeur écrit et publié, Said en était venu à réévaluer l’apport exceptionnel de son prédécesseur, non seulement en termes d’érudition, mais aussi sur le plan du renouvellement d’une pensée occidentale sur l’Orient, dépourvue, précisément, de toute volonté de domination. Il fit en tout cas traduire en anglais La Renaissance orientale et lui adjoignit une préface extrêmement élogieuse, rendant ainsi hommage, tardivement, mais de manière éclatante, à la démarche profondément humaniste de Schwab, dans laquelle, sans doute, Said se reconnaissait aussi.
La musique sur Internet, entre effets de génération et paradoxe social : quelques pistes
Authors: Leteinturier Christine
Published: December 2014

Cette contribution à l’étude de la musique sur Internet est une synthèse de travaux d’étudiants de Master 1 Information-Communication de l’Institut Français de Presse (université Panthéon-Assas). S’intéressant soit à la musique techno, soit à la musique classique, ils ont cherché à comprendre ce que l’Internet fait moins à la musique qu’aux musiciens et aux mélomanes autour de deux courants musicaux, la musique électro-techno et la musique classique. Musique populaire, mais surtout musique « jeune » la techno a rapidement trouvé sa place sur l’Internet tant du côté de la production musicale que des dispositifs d’évaluation des artistes et des échanges de sons, du fait même de sa proximité forte aux TIC. Du côté de la musique classique, les réticences à l’usage de l’Internet soit pour écouter soit pour reconfigurer les formes de socialisation autour de ce genre musical sont nombreuses. Si les plus jeunes mélomanes et instrumentistes s’essaient à l’Internet, les réticences restent fortes. L’effet génération joue moins et le goût pour le vivant persiste, largement porté par des pratiques très ancrées et les générations plus âgées qui dans ce domaine, n’ont qu’un usage très utilitariste de l’Internet. Appartenances sociales, culturelles et générationnelles construisent des relations variées, voire contradictoire avec l’Internet musical.
Écran(s)
Authors: Seux Christine
Published: December 2014

Résumé : L’auteure s’appuie sur le concept foucaldien de dispositif pour analyser les différentes formes et fonctions des “écrans” – de cinéma, de télévision, de téléphone, d’ordinateur, etc. Leurs premiers paradoxes sont de faire voir et de se rendre invisibles, d’être statiques et dynamiques, de mettre à distance et de jouer dans l’intimité… L’écran, par l’imposition de sa naturalité, format “paysage”, fenêtre sur le monde, fait oublier ses artifices et norme nos perceptions. En ouvrant aux espaces de l’imaginaire (le cinéma), en séduisant par son immédiateté au réel (la télévision) et par sa scénarisation interactive (les jeux vidéo), il confirme son pouvoir hypnotique. L’écran de l’ordinateur et de ses avatars constitue ainsi une interface universelle douée d’ubiquité, façonnant pour son utilisateur un sentiment de toute-puissance alors qu’il gouverne nos choix et nous gouverne.
Exercices et pratiques éthopoïétiques : la compétence éthique dans la formation des maîtres
Authors: Dupeyron Jean-François
Published: December 2014

Résumé : En introduisant la notion de “compétence éthique” dans les objectifs de formation des enseignants, le Ministère soulevait un problème double. Le premier, d’ordre théorique, met en doute la pertinence de la notion de compétence dans les domaines de la formation morale (laïque) des élèves et de l’éthique professionnelle. Mais il y avait une seconde difficulté que Jean-François Dupeyron prend à bras-le-corps : quel est le sens, in fine , de cette question, et quel sens donner à l’idée d’un “savoir” éthique qui serait en jeu dans la formation ? Il examine la question à partir de Foucault, Durkheim et Gadamer pour montrer que s’il s’agit de la connaissance de codes sociaux, l’enjeu est encore de leur interprétation et du “travail sur soi” dans et par l’action qui en découle, soit encore la question de leur “application” non pas technique mais “phronétique”. Une telle orientation invalide toute position kantienne du sujet mais la théorie du care ne constitue pas selon l’auteur une alternative satisfaisante. Reste alors la problématique ouverte par Michel Foucault d’une “autopoïétique”, mais J.-F. Dupeyron montre aussi qu’elle ne peut être acceptée sans quelque précaution critique.
Relations fraternelles et déficience intellectuelle, la parentalisation en question
Authors: Griot Marion , Poussin Marjorie , Baltenneck Nicolas
Published: December 2014

Cet article traite du type de relation qui s’établit dans les fratries atypiques dans lesquelles un des membres est atteint de déficience intellectuelle. A partir des résultats d’une recherche antérieure qui a permis d’identifier les spécificités apparaissant dans le lien entre l’enfant handicapé et son frère ou sa sœur, deux études de cas sont proposées. Celles-ci permettent de définir et d’illustrer les processus de parentalisation et/ou de parentification qui peuvent apparaître dans ces fratries. Un pont entre la recherche et la pratique clinique est proposé dans cet article par l’évocation de pistes d’interventions auprès des systèmes familiaux confrontés à la déficience intellectuelle d’un de ses membres.
Héros ou « Fan-atisme » adolescent ? Entre modèle et inspiration. Actualité de la question du trauma à l'adolescence
Authors: Perret Anne
Published: December 2014

À partir de la situation d’Eugénie, fan de Justin Biber, nous tenterons de montrer comment l’usage de cette figure héroïque actualise la dimension du trauma propre à l’adolescence. L’addiction fanatique à cette figure héroïque serait peut-être à rapporter à l’addiction au corps, qui constitue une des formes contemporaines de réponse à la rencontre avec le réel pubertaire. Une voie de symbolisation semble cependant se tracer à travers le corps de l’autre, ce qui ferait alors du semblable une voie vers la nomination.
« an emasculated, infantile complain-ee »
Authors: Cornalba Vincent
Published: December 2014

Cette contribution s’appuie sur l’hypothèse suivante : à l’adolescence, le recours au sacrifice relève aussi du registre d’une perte consentie. Elle s’établirait autour de trois opérations successives en même temps qu’articulées les unes aux autres : offrir en sacrifice, procéder au sacrifice et achever son sacrifice. C’est à l’étude de ces trois moments organisateurs dans l’évolution du fonctionnement psychique au pubertaire que l’auteur de ce présent article se consacre.
Les sacrements comme signes qui font ce qu'ils signifient : signe efficace vs. efficacité symbolique
Authors: Rosier-Catach Irène
Published: December 2014

Résumé Les théologiens médiévaux écrivent de longs chapitres sur le sacrement, signe très particulier qui « fait ce qu’il signifie », cette caractéristique se retrouvant assignée à la formule, qui avec la matière, le constitue, formule qui ainsi se voit décrite comme un énoncé performatif ou « opératif », pour reprendre le terme de l’époque. Les discussions sur le sacrement en tant que signe et cause amènent à forger la catégorie de « signe efficace », dont la description donnée par Duns Scot est la plus précise. Traduire le « signe » des médiévaux, décrit à partir des définitions augustiniennes, par « symbole » n’a pas de légitimité. Tous les traits distinctifs assignés à cette catégorie floue de « symbole » sont en fait unanimement et uniquement celles du signe sacramentel : le passage du visible à l’invisible, la notion de pacte ou de contrat, la fonction de médiation et de reconnaissance, l’engagement des parties, le caractère institutionnel ou naturel, rituel et intentionnel. C’est précisément à saisir la profonde cohérence de toutes ces caractéristiques, et l’arbitraire qu’il y aurait à les séparer pour y retrouver du signe vs du symbole, qu’est consacré le présent travail.
À travers l'instant blanc, les poèmes du début
Authors: Sourdillon Jean-Marc
Published: December 2014

Résumé Il s’agit dans cette étude d’une petite traversée de l’œuvre de Jean-Pierre Lemaire, d’une remontée depuis le premier poème jusqu’aux écrits plus récents pour dégager le mouvement d’une poésie orientée tout entière vers l’autre, vers les autres et ce qui, à travers eux, se dessine, de la présence du Christ. L’analyse du premier poème, surgi comme un cri des profondeurs du moi blessé, nous révèle que tout poème signale le retour à l’origine de la parole et que celle-ci se définit par une abolition fugitive du moi poétique laissant passage à la venue de l’autre, manifesté et rejoint dans sa fragilité essentielle. L’attitude qui s’impose par conséquent pour le poète est celle d’une vulnérabilité offerte. Elle ne va pas sans douleur mais, une fois renversée en accueil, elle inaugure le retour à la paix sous la forme de la musique perceptible dans le vers. Tout poème de Jean-Pierre Lemaire est en effet un cri apaisé en musique dans la mesure où, grâce à la progression de la parole, les contours du moi se sont dissous au profit d’une sorte d’espace où les frontières, les murs qui empêchent de reconnaître se sont effacés, où tout devient visible, considérable, où chacun peut apparaître tel qu’il naît, avec sa frange de possible, sans crainte d’être jugé – seulement accueilli dans un regard disponible et aimant, le regard de la Sagesse qui, dans une fulgurance bouleversante, parfois nous traverse.
L'Art contemporain et le christianisme : malentendu créatif et fulgurances
Authors: Rinuy Paul-Louis
Published: December 2014

Résumé Les rapports entre l’art contemporain et le christianisme sont souvent marqués par un malentendu de part et d’autre, mais ce malentendu se révèle en fait extrêmement créatif. En témoigne notamment la Querelle de l’Art Sacré (vers 1950) consécutive à la présentation du Christ de Germaine Richier dans l’Église d’Assy. Dans l’art d’aujourd’hui, on peut remarquer des convergences entre certaines préoccupations d’artistes majeurs (Ernest Pignon-Ernest, Arnulf Rainer ou Bill Viola, par exemple) et quelques traits essentiels du christianisme: importance de l’Incarnation, valorisation de l’histoire humaine, regard, à la fois émerveillé et effrayé, devant la réalité du monde.
« Gallierock », Jean-Paul II et Jean-Charles de Castelbajac
Authors: Cotta Laurent
Published: December 2014

Résumé L’exposition « Gallierock » au Musée Galliera en 2007 n’est pas qu’une rétrospective de l’œuvre créatrice de Jean-Charles de Castelbajac. La mise en scène de l’exposition imaginée par le couturier est aussi une manière de rendre le musée vivant. Elle invite le public à toucher l’histoire à travers les vêtements exposés en particulier dans le cabinet de curiosités où figure notamment la chasuble dessinée pour les JMJ de 1997. Elle pose aussi la question de la transformation d’un vêtement de mode en œuvre muséographique.
