Published: September 2017

This work reports the effect of co-sensitization of nanoporous titanium dioxide using Cadmium Sulfide (CdS) and poly(3-hexylthiophene) (P3HT) on the performance of hybrid solar cells. CdS nanolayer with different thicknesses was grown on Titanium Dioxide (TiO2) nanoparticles by chemical bath deposition technique with varying deposition times. Both atomic force microscopy (AFM) and UV–Vis–NIR spectroscopy measurements of TiO2 electrode sensitized with and without CdS layer confirm that the existence of CdS layer on TiO2 nanoparticles. AFM images of CdS-coated TiO2 nanoparticles show that the surface roughness of the TiO2 nanoparticle samples decreases with increasing CdS deposition times. Current density–voltage and external quantum efficiency (EQE) measurements were carried out for corresponding solar cells. Both short circuit current density (JSC) and fill factor were optimized at the CdS deposition time of 12 min. On the other hand, a steady and continuous increment in the open circuit voltage (VOC) was observed with increasing CdS deposition time and increased up to 0.81 V when the deposition time was 24 min. This may be attributed to the increased gradual separation of P3HT and TiO2 phases and their isolation at the interfaces. The higher VOC of 0.81 V was due to the higher built-in voltage at the CdS–P3HT interface when compared to that at the TiO2–P3HT interface. Optimized nanoporous TiO2 solar cells with CdS and P3HT co-sensitizers showed external quantum efficiency (EQE) of over 40% and 80% at the wavelengths corresponding to strong absorption of the polymer and CdS, respectively. The cells showed an overall average efficiency of over 2.4% under the illumination of 70 mW/cm2 at AM 1.5 condition.

Published: September 2017

Water-limited ecosystems encompass approximately 40% of terrestrial land mass and play a critical role in modulating Earth’s climate and provisioning ecosystem services to humanity. Spaceborne remote sensing is a critical tool for characterizing ecohydrologic patterns and advancing the understanding of the interactions between atmospheric forcings and ecohydrologic responses. Fine to medium scale spatial and temporal resolutions are needed to capture the spatial heterogeneity and the temporally intermittent response of these ecosystems to environmental forcings. Techniques combining complementary remote sensing datasets have been developed, but the heterogeneous nature of these regions present significant challenges. Here we investigate the capacity of one such approach, the Spatial and Temporal Adaptive Reflectance Fusion Model (STARFM) algorithm, to map Normalized Difference Vegetation Index (NDVI) at 30 m spatial resolution and at a daily temporal resolution in an experimental watershed in southwest Idaho, USA. The Dry Creek Experimental Watershed captures an ecotone from a sagebrush steppe ecosystem to evergreen needle-leaf forests along an approximately 1000 m elevation gradient. We used STARFM to fuse NDVI retrievals from the MODerate-resolution Imaging Spectroradiometer (MODIS) and Landsat during the course of a growing season (April to September). Specifically we input to STARFM a pair of Landsat NDVI retrievals bracketing a sequence of daily MODIS NDVI retrievals to yield daily estimates of NDVI at resolutions of 30 m. In a suite of data denial experiments we compared these STARFM predictions against corresponding Landsat NDVI retrievals and characterized errors in predicted NDVI. We investigated how errors vary as a function of vegetation functional type and topographic aspect. We find that errors in predicting NDVI were highest during green-up and senescence and lowest during the middle of the growing season. Absolute errors were generally greatest in tree-covered portions of the watershed and lowest in locations characterized by grasses/bare ground. On average, relative errors in predicted average NDVI were greatest in grass/bare ground regions, on south-facing aspects, and at the height of the growing season. We present several ramifications revealed in this study for the use of multi-sensor remote sensing data for the study of spatiotemporal ecohydrologic patterns in dryland ecosystems.
Ship Detection in Optical Remote Sensing Images Based on Wavelet Transform and Multi-Level False Alarm Identification
Authors: Xu Fang , Liu Jinghong , Dong Chao , Wang Xuan
Published: September 2017

Ship detection by Unmanned Airborne Vehicles (UAVs) and satellites plays an important role in a spectrum of related military and civil applications. To improve the detection efficiency, accuracy, and speed, a novel ship detection method from coarse to fine is presented. Ship targets are viewed as uncommon regions in the sea background caused by the differences in colors, textures, shapes, or other factors. Inspired by this fact, a global saliency model is constructed based on high-frequency coefficients of the multi-scale and multi-direction wavelet decomposition, which can characterize different feature information from edge to texture of the input image. To further reduce the false alarms, a new and effective multi-level discrimination method is designed based on the improved entropy and pixel distribution, which is robust against the interferences introduced by islands, coastlines, clouds, and shadows. The experimental results on optical remote sensing images validate that the presented saliency model outperforms the comparative models in terms of the area under the receiver operating characteristic curves core and the accuracy in the images with different sizes. After the target identification, the locations and the number of the ships in various sizes and colors can be detected accurately and fast with high robustness.
A Methodology for the Design of Application-Specific Cyber-Physical Social Sensing Co-Simulators
Authors: Sánchez Borja Bordel , Alcarria Ramón , Sánchez-Picot Álvaro , Sánchez-de-Rivera Diego
Published: September 2017

Cyber-Physical Social Sensing (CPSS) is a new trend in the context of pervasive sensing. In these new systems, various domains coexist in time, evolve together and influence each other. Thus, application-specific tools are necessary for specifying and validating designs and simulating systems. However, nowadays, different tools are employed to simulate each domain independently. Mainly, the cause of the lack of co-simulation instruments to simulate all domains together is the extreme difficulty of combining and synchronizing various tools. In order to reduce that difficulty, an adequate architecture for the final co-simulator must be selected. Therefore, in this paper the authors investigate and propose a methodology for the design of CPSS co-simulation tools. The paper describes the four steps that software architects should follow in order to design the most adequate co-simulator for a certain application, considering the final users’ needs and requirements and various additional factors such as the development team’s experience. Moreover, the first practical use case of the proposed methodology is provided. An experimental validation is also included in order to evaluate the performing of the proposed co-simulator and to determine the correctness of the proposal.
A New Proxy Measurement Algorithm with Application to the Estimation of Vertical Ground Reaction Forces Using Wearable Sensors

Published: September 2017

Measurement of the ground reaction forces (GRF) during walking is typically limited to laboratory settings, and only short observations using wearable pressure insoles have been reported so far. In this study, a new proxy measurement method is proposed to estimate the vertical component of the GRF (vGRF) from wearable accelerometer signals. The accelerations are used as the proxy variable. An orthogonal forward regression algorithm (OFR) is employed to identify the dynamic relationships between the proxy variables and the measured vGRF using pressure-sensing insoles. The obtained model, which represents the connection between the proxy variable and the vGRF, is then used to predict the latter. The results have been validated using pressure insoles data collected from nine healthy individuals under two outdoor walking tasks in non-laboratory settings. The results show that the vGRFs can be reconstructed with high accuracy (with an average prediction error of less than 5.0%) using only one wearable sensor mounted at the waist (L5, fifth lumbar vertebra). Proxy measures with different sensor positions are also discussed. Results show that the waist acceleration-based proxy measurement is more stable with less inter-task and inter-subject variability than the proxy measures based on forehead level accelerations. The proposed proxy measure provides a promising low-cost method for monitoring ground reaction forces in real-life settings and introduces a novel generic approach for replacing the direct determination of difficult to measure variables in many applications.
Tip Pressure on Semicircular Specimens in Tapping Mode Atomic Force Microscopy in Viscous Fluid Environments
Authors: Shih Hua-Ju , Dai Ching-Liang , Shih Po-Jen
Published: September 2017

Tapping mode (TM) atomic force microscopy (AFM) in a liquid environment is widely used to measure the contours of biological specimens. The TM triggers the AFM probe approximately at the resonant frequencies and controls the tip such that it periodically touches the specimen along the scanning path. The AFM probe and its tip produce a hydrodynamic pressure on the probe itself and press the specimen. The tip to specimen size ratio is known to affect the measurement accuracy of AFM, however, few studies have focused on the hydrodynamic pressure caused by the effects of specimen size. Such pressure affects the contour distortion of the biological specimen. In this study, a semi-analytical method is employed for a semicircular specimen to analyze the vorticity and pressure distributions for specimens of various sizes and at various tip locations. Changes in pressure distribution, fluid spin motion, and specimen deformation are identified as the tip approaches the specimen. The results indicate the following: the specimen surface experiences the highest pressure when the specimen diameter equals the tip width; the vorticity between tip and specimen is complex when the tip is close to the specimen center line; and the specimen inflates when the tip is aligned with the specimen center line.

Published: September 2017

The IEEE 802.15.4e standard has four different superframe structures for different applications. Use of a low latency deterministic network (LLDN) superframe for the wireless sensor network is one of them, which can operate in a star topology. In this paper, a new channel access mechanism for IEEE 802.15.4e-based LLDN shared slots is proposed, and analytical models are designed based on this channel access mechanism. A prediction model is designed to estimate the possible number of retransmission slots based on the number of failed transmissions. Performance analysis in terms of data transmission reliability, delay, throughput and energy consumption are provided based on our proposed designs. Our designs are validated for simulation and analytical results, and it is observed that the simulation results well match with the analytical ones. Besides, our designs are compared with the IEEE 802.15.4 MAC mechanism, and it is shown that ours outperforms in terms of throughput, energy consumption, delay and reliability.
Stormwater Treatment Evaluation of a Constructed Floating Wetland after Two Years Operation in an Urban Catchment
Authors: Walker Christopher , Tondera Katharina , Lucke Terry
Published: September 2017

Constructed Floating Wetlands (CFW) for stormwater treatment are increasingly used to treat urban runoff. However, studies of large-scale systems and the long-term evaluation of their treatment efficiency are scarce. This article presents the final results of a two-year study of the pollutant removal performance of a CFW in a stormwater pond capturing runoff from a low-residential catchment in South-East Queensland (Australia) under subtropical conditions. Although the CFW treatment area to catchment ratio was only 0.14%, the results demonstrated a significant removal of both Total Suspended Solids (TSS) and Total Phosphorus (TP) from the stormwater inflows by the CFW. The efficiency ratios for TSS and TP were 81% and 52%, respectively. While the removal rate for total nitrogen was not significant for the CFW evaluated in this study, the ER was still 17%. However, the ERs for nitrate and nitrogen oxide were both 47%. The study results suggest that it may be possible to increase the pollution removal performance of the CFW by upsizing the system and including intermittent re-aeration zones in the surrounding stormwater pond. The results of this research study clearly demonstrate that CFW can be an effective treatment solution for the removal of pollution from urban stormwater runoff.
Assessment of the Tourism’s Potential as a Sustainable Development Instrument in Terms of Annual Stability: Application to Spanish Rural Destinations in Process of Consolidation
Authors: Martín Martín José , Salinas Fernández Jose , Rodríguez Martín José , Jiménez Aguilera Juan
Published: September 2017

Tourism has established itself as an instrument that supports the sustainable development of rural destinations and has both, negative and positive effects. The annual instability of the flow of visitors, known as tourist seasonality, contributes to the intensification of some of these negative effects. In this work, we perform an analysis on the evolution of the seasonality intensity during the process of consolidation of the Spanish rural destinations, designed to improve the knowledge about the tourist activity’s capacity to generate a sustainable development alternative steady throughout the year. To guarantee an accurate measurement, we propose the use of a synthetic indicator as a methodological innovation, such as the Method of Distance Pena DP2, that brings together the supply and demand variables. We can observe that tourist seasonality is restrained in smaller destinations that experience a growth in terms of tourists’ arrivals, so it is associated with the early stages of the consolidation process. However, the destinations with a lower seasonality level do not match with those that welcome a larger number of visitors. Those destinations with the potential to obtain more benefits because of their level of consolidation do not have the necessary annual stability to provide employment and income in a steady way throughout the year.
Development and Piloting of Sustainability Assessment Metrics for Arctic Process Industry in Finland—The Biorefinery Investment and Slag Processing Service Cases
Authors: Husgafvel Roope , Poikela Kari , Honkatukia Juha , Dahl Olli
Published: September 2017

Regionally, there has been a lot of focus on the advancement of sustainable arctic industry and circular economy activities within process industry in the Finnish Lapland. In this study, collaboration between university and industry was established facilitated by regional development actors to develop and pilot test a sustainability assessment approach taking into account previous work in this field. The industry partners in this study were a biorefinery investment in the first case and a slag processing service in the second case. As a result of the joint efforts, novel sets of environmental and economic sustainability assessment indicators and associated sub-indicators were developed and the existing set of social indicators was updated. Moreover, environmental and social sustainability assessments were implemented in the biorefinery case accompanied by a separate evaluation of regional economic impacts. In the slag processing case, environmental, economic and social sustainability were assessed. The results of the sustainability assessments indicated very good level of overall performance in both cases. However, specific elements that contributed to lower level of performance included lack of specific sustainability management and reporting approaches and need for better performance in supply chain sustainability, monitoring of greenhouse gas emissions, life cycle thinking and circular economy training. The expected effects of the planned investment on the regional economy were very positive based on the results of the evaluation.
Normative Beliefs, Attitudes, and Social Norms: People Reduce Waste as an Index of Social Relationships When Spending Leisure Time
Authors: Fang Wei-Ta , Ng Eric , Wang Ching-Ming , Hsu Ming-Lin
Published: September 2017

This study has adopted and refined Ajzen’s theory of planned behavior, theory of reasoned action, and the value–belief–norm theory by Stern et al. to investigate the effects of normative beliefs, attitudes, and social norms on pro-environmental behavioral intentions. A total of 391 valid responses were collected from visitors to a theme park in Taiwan. A structure equation analysis indicated that the overall fit of the proposed model was supported. It was also found that both attitudes and social norms had positive and significant influence on waste reduction. While the results did not reveal any direct relation between normative beliefs and behavioral intentions, normative beliefs had positive direct influence on social norms and attitudes, which in turn had an impact on behavioral intentions. The findings provided further insights about pro-environmental behavioral intentions from an Asia perspective and highlighted important implications for environmental policies and education to reduce waste.
Direct Impacts of an Urban Living Lab from the Participants’ Perspective: Livewell Yarra
Authors: Sharp Darren , Salter Robert
Published: September 2017

Urban living labs have emerged as transition arenas for undertaking process-oriented and reflexive experiments in the multi-stakeholder governance of sustainability. This paper evaluates Livewell Yarra, an urban living lab in Melbourne, Australia, that brought together academic researchers and community actors to engage in experiments for low-carbon living. This paper evaluates transition team experiments in governance of the lab itself and community experiments in carbon reduction that took place in people’s homes and small group settings known as decarb groups. This paper’s primary research question is: what are the direct impacts of urban living lab experiments from the participants’ perspective? The research methods utilised include action research, asset-based community development, participatory co-design and most significant change research. This paper evaluates experiments in low-carbon living through data collected via stories of change from participant interviews. The results indicate that experiments in urban living labs create opportunities for social learning and empowerment, but also raise issues of leadership and ownership of transition governance. The findings suggest that Livewell Yarra could have benefited from clearer agenda setting and continuous monitoring to feedback results. The paper concludes by suggesting future research directions that utilise the operational processes of transition management to support experiments in urban living labs.

Published: September 2017

Botulism is a fatal intoxication caused by botulinum neurotoxins (BoNTs), which are mainly produced by Clostridium botulinum and characterized by flaccid paralysis. The BoNTs C and D are the main serotypes responsible for botulism in animals, including buffaloes. Botulism is one of the leading causes of death in adult ruminants in Brazil due to the high mortality rates, even though botulism in buffaloes is poorly reported and does not reflect the real economic impact of this disease in Brazilian herds. Vaccination is reported as the most important prophylactic measure for botulism control, although there are no specific vaccines commercially available for buffaloes in Brazil. This study aimed to evaluate the humoral immune response of buffalo groups vaccinated with three different concentrations of recombinant proteins (100, 200, and 400 µg) against BoNTs serotypes C and D as well as to compare the groups to each other and with a group vaccinated with a bivalent commercial toxoid. The recombinant vaccine with a concentration of 400 μg of proteins induced the highest titers among the tested vaccines and was proven to be the best choice among the formulations evaluated and should be considered as a potential vaccine against botulism in buffalo.
Management Scenarios of the Grand Ethiopian Renaissance Dam and Their Impacts under Recent and Future Climates
Authors: Liersch Stefan , Koch Hagen , Hattermann Fred
Published: September 2017

Close to the border with Sudan, Ethiopia is currently building the largest hydroelectric power plant in Africa with a storage volume corresponding to approximately 1.5 years of the mean discharges of the Blue Nile. This endeavor is controversially debated in the public and the scientific literature. Contributing to this discussion, by shading some light on climate change issues, an eco-hydrological model, equipped with a reservoir module, was applied to investigate downstream hydrological impacts during filling and regular operation, the latter considering climate change projected by an ensemble of 10 global and regional climate models. Our results show that at the earliest after 20 months, the dam could produce hydroelectric power. Full supply level may be reached after four years or not at all, depending on filling policies and assumptions of seepage rates. Under recent hydro-climatic conditions, the dam may produce 13 TWh − a , which is below the envisaged target of 15.7 TWh − a . The ensemble mean suggests slightly increasing hydropower production in the future. Almost independently of the operation rules, the highly variable discharge regime will be significantly altered to a regime with almost equal flows each month. Achieving a win-win situation for all riparian countries requires a high level of cooperation in managing the Eastern Nile water resources.
Bi-layer sandwich film for antibacterial catheters

Published: September 2017

Background: Approximately one quarter of all nosocomial infections can be attributed to the urinary tract. The infections are supposed to be mainly caused by implantations of urethral catheters and stents. A new catheter design is introduced with the aim to lower the high number of nosocomial urethral infections. In order to avoid limitations to use, the design is first applied to conventional commercially available balloon catheters.

Results: The main feature of the design is a sandwich layer on both sides of the catheter wall, which is composed of a fragmented base layer of silver capped by a thin film of poly(p-xylylene). This top layer is mainly designed to release a controlled amount of Ag+ ions, which is bactericidal, but not toxic to humans. Simultaneously, the lifetime is prolonged to at least one year. The base layer is electrolessly deposited applying Tollens’ reagens, the cap layer is deposited by using chemical vapor deposition.

Conclusion: The three main problems of this process, electroless deposition of a fragmented silver film on the surface of an electrically insulating organic polymer, irreproducible evaporation during heating of the precursor, and exponential decrease of the layer thickness along the capillary, have been solved trough the application of a simple electrochemical reaction and two standard principles of physics: Papin’s pot and the principle of Le Chatelier.

We present new adaptive optics (AO) imaging and spectroscopic measurements of Galactic center source G1 from W. M. Keck Observatory. Our goal is to understand its nature and relationship to G2, which is the first example of a spatially resolved object interacting with a supermassive black hole (SMBH). Both objects have been monitored with AO for the past decade (2003–2014) and are comparatively close to the black hole (a
min ∼ 200–300 au) on very eccentric orbits (e
G1 ∼ 0.99; e
G2 ∼ 0.96). While G2 has been tracked before and during periapsis passage (T
0 ∼ 2014.2), G1 has been followed since soon after emerging from periapsis (T
0 ∼ 2001.3). Our observations of G1 double the previously reported observational time baseline, which improves its orbital parameter determinations. G1's orbital trajectory appears to be in the same plane as that of G2 but with a significantly different argument of periapsis (Δω = 21° ± 4°). This suggests that G1 is an independent object and not part of a gas stream containing G2, as has been proposed. Furthermore, we show for the first time that (1) G1 is extended in the epochs closest to periapsis along the direction of orbital motion, and (2) it becomes significantly smaller over time (450 au in 2004 to less than 170 au in 2009). Based on these observations, G1 appears to be the second example of an object tidally interacting with an SMBH. G1's existence 14 yr after periapsis, along with its compactness in epochs further from the time of periapsis, suggest that this source is stellar in nature.

The He ii transverse proximity effect—enhanced He ii

transmission in a background sightline caused by the ionizing radiation of a foreground quasar—offers a unique opportunity to probe the morphology of quasar-driven He ii reionization. We conduct a comprehensive spectroscopic survey to find

quasars in the foreground of 22 background quasar sightlines with Hubble Space Telescope/COS He ii

transmission spectra. With our two-tiered survey strategy, consisting of a deep pencil-beam survey and a shallow wide-field survey, we discover 131 new quasars, which we complement with known SDSS/BOSS quasars in our fields. Using a restricted sample of 66 foreground quasars with inferred He ii photoionization rates greater than the expected UV background at these redshifts (

) we perform the first statistical analysis of the He ii transverse proximity effect. Our results show qualitative evidence for a large object-to-object variance: among the four foreground quasars with the highest

only one (previously known) quasar is associated with a significant He ii transmission spike. We perform a stacking analysis to average down these fluctuations, and detect an excess in the average He ii transmission near the foreground quasars at

significance. This statistical evidence for the transverse proximity effect is corroborated by a clear dependence of the signal strength on

We investigate the relation between star formation rate (SFR) and stellar mass (M), i.e., the main sequence (MS) relation of star-forming galaxies, at

in the first four Hubble Space Telescope (HST) Frontier Fields, on the basis of rest-frame UV observations. Gravitational lensing combined with deep HST observations allows us to extend the analysis of the MS down to

at

and

at higher redshifts, a factor of ∼10 below most previous results. We perform an accurate simulation to take into account the effect of observational uncertainties and correct for the Eddington bias. This step allows us to reliably measure the MS and in particular its slope. While the normalization increases with redshift, we fit an unevolving and approximately linear slope. We nicely extend to lower masses the results of brighter surveys. Thanks to the large dynamic range in mass and by making use of the simulation, we analyzed any possible mass dependence of the dispersion around the MS. We find tentative evidence that the scatter decreases with increasing mass, suggesting a larger variety of star formation histories in low-mass galaxies. This trend agrees with theoretical predictions and is explained as either a consequence of the smaller number of progenitors of low-mass galaxies in a hierarchical scenario and/or of the efficient but intermittent stellar feedback processes in low-mass halos. Finally, we observe an increase in the SFR per unit stellar mass with redshift milder than predicted by theoretical models, implying a still incomplete understanding of the processes responsible for galaxy growth.

We report the results of searches for strong gravitational lens systems in the Dark Energy Survey (DES) Science Verification and Year 1 observations. The Science Verification data span approximately 250 sq. deg. with a median i-band limiting magnitude for extended objects (10σ) of 23.0. The Year 1 data span approximately 2000 sq. deg. and have an i-band limiting magnitude for extended objects (10σ) of 22.9. As these data sets are both wide and deep, they are particularly useful for identifying strong gravitational lens candidates. Potential strong gravitational lens candidate systems were initially identified based on a color and magnitude selection in the DES object catalogs or because the system is at the location of a previously identified galaxy cluster. Cutout images of potential candidates were then visually scanned using an object viewer and numerically ranked according to whether or not we judged them to be likely strong gravitational lens systems. Having scanned nearly 400,000 cutouts, we present 374 candidate strong lens systems, of which 348 are identified for the first time. We provide the R.A. and decl., the magnitudes and photometric properties of the lens and source objects, and the distance (radius) of the source(s) from the lens center for each system.
Co-excitation libidinale et établissement des premiers liens : l’exemple de l’anorexie du bébé
Authors: Cascales Thomas
Published: September 2017

L’établissement des premiers liens entre des parents et un bébé engage la mutualisation des mouvements libidinaux de chacun des partenaires. Ce travail d’investissement est conditionné par la transformation psychique de l’excitation en pulsionnalité à partir de la dialectique intersubjective sujet/objet. L’anorexie du bébé, en tant que trouble précoce de l’investissement libidinal, est un terrain fécond de compréhension de la complexité de cette dialectique. Ce trouble précoce souligne comment la perturbation des investissements libidinaux peut avoir des répercussions sur la construction intrapsychique individuelle et la dynamique intersubjective parents/bébé.
Originalités de la clinique du sujet adulte, souffrant de psychose infantile, en psychiatrie

Published: September 2017

Dans le contexte des remaniements épistémologiques en psychiatrie de notre époque, il semble intéressant de soutenir la diversité des exercices de la psychiatrie. À partir d’un cas de notre pratique de psychologue, auprès de sujets adultes souffrant de psychoses infantiles, et hospitalisés en unité de soins psychiatriques, nous tenterons de répondre à ces questions : comment aider le sujet schizophrène lorsqu’il n’a trouvé aucune boussole pour orienter son monde, pour faire avec son corps, les autres et les objets ? De quoi souffre le sujet dit « schizophrène », lorsque parler ou même circuler dans le monde apparaissent comme dangereux ? Comment dès lors le sujet supporte-t-il un monde tramé par le symbolique, et plus encore une institution qui se soutient du langage commun ? Puis, à partir de nos travaux de recherche sur l’actualité des traitements de la schizophrénie, nous tenterons de dégager le statut théorique de l’usage des semblants par le sujet et ses partenaires, en tant qu’espace d’invention.
Body-hacking et logique supplétive : un mode contemporain de traitement du corps
Authors: Peoc’h Mickaël , Druel Gwénola
Published: September 2017

La pratique du body-hacking (pirater son corps) est indubitablement postmoderne. Apparue au XXI e siècle, elle fait le pari que l’évolution passera par l’hybridation de l’humain avec la machine. Si le mouvement fédère un nombre relativement important d’amateurs ou de curieux, les discours de quelques pionniers ne sont pas sans enseignements quant aux possibilités de suppléer à l’image d’un corps parlant désinvesti, incomplet ou inefficace. Qu’il s’agisse de résoudre le non-rapport sexuel, de localiser dans le corps des capteurs de jouissance ou de voiler le réel du corps, le body-hacking possède l’avantage de venir habiller, et donc potentiellement circonscrire, des pratiques proches de la mutilation. Elle s’enracine de plus dans un lien social relativement riche, par le biais des réseaux sociaux virtuels notamment. Les témoignages de certains hackers , sont ainsi très précieux pour explorer l’élaboration progressive des constructions symptomatiques faisant barrage à la jouissance.
La liberté du sujet face au déterminisme psychique. La question d’une « volonté inconsciente »
Authors: Godart Elsa
Published: September 2017

Qu’est-ce qui fait agir le corps et l’esprit, quand on se trouve au-delà de toute volonté ? Qu’est-ce qui permet de choisir tel ou tel comportement à adopter, alors même que la volonté consciente paraît déchue ? L’inconscient sans nul doute. À ce moment-là, plus que jamais « je n’est plus le maître dans sa propre demeure », ce qui n’empêche pas je d’exister pour autant. Dès lors, force est d’admettre que l’inconscient semble choisir pour nous telle ou telle réaction du corps ou encore tel ou tel lapsus. Mais justement qu’est-ce à dire que l’inconscient « choisit » pour nous ? Il est aberrant de parler dans ce cas d’une volonté, car la volonté implique la raison et surtout un être conscient de lui-même, capable de faire des choix. Or, quels sont les fondements de l’action ? Il s’agit de postuler que l’agir issu de l’inconscient a un sens, et répond à une élection, à une « sorte » d’intentionnalité. Cela soulève également la question plus énigmatique du déterminisme psychique. Autant d’interrogations qui nous ramènent toutes à une seule : la volonté et plus particulièrement à la question d’une volonté sans sujet – ou d’une « volonté inconsciente ».
Dette de vie, l’aliénation imaginaire du sujet greffé
Authors: Marchais Claire
Published: September 2017

La transplantation confronte brutalement le sujet au réel traumatique d’un corps hybride et marqué par les traces de sa métamorphose. Sortir de la sidération psychique que cela peut provoquer, nécessite un travail de symbolisation permettant de recouvrir d’une trame imaginaire la béance laissée par le trauma. Ce processus fait bien souvent émerger une problématique de don et de dette propre à la greffe. Dans le cas de transplantations présupposant le décès du donneur, le receveur qui pense la relation de don sur une modalité quantitative d’échange se trouve alors aliéné à une dette sans limite. Nous illustrerons avec l’histoire de deux patients greffés combien, dans un tel cas, l’enjeu serait de changer de paradigme dans leur mode de relation au donneur. L’ Essai sur le don de M. Mauss décrit un modèle relationnel où l’endettement du receveur se situe sur un registre qualitatif, mettant l’accent sur la possibilité pour le receveur de choisir son contre-don et celui à qui il l’adresse. Nous montrerons alors que ce modèle constitue un paradigme étayant pour penser la relation au donneur dans la transplantation d’organe.
Le désir infanticide, une dialectique maternelle de l’entre-deux
Authors: Gallois Amélie
Published: September 2017

À l’extraordinaire de l’acte infanticide, répond un désir infanticide somme toute ordinaire mais ô combien insupportable. Ce désir n’est ni maternel, ni féminin : il se glisse dans l’entre-deux de ces positions, épousant les contours d’une subjectivation morcelée entre être et avoir qui tente de s’unifier via une dyade mère-fille protéiforme. L’enfant mettant à mal ce fragile montage, le désir infanticide maternel semble alors émerger pour combler la béance que le corps de l’enfant ouvre. C’est par le couple formé avec le père de l’enfant, nouvelle figure d’une dyade mère-fille sans cesse réinventée, que cette dernière va tenter d’élaborer son désir infanticide ; à moins que cette tentative n’échoue et ne précipite le passage à l’acte infanticide.
Comment être vénitien ? Identification des immigrants et « droit d’habiter » à Venise au XVI e siècle
Authors: Salzberg Rosa M. , Judde de Larivière Claire
Published: September 2017

Au XVI e siècle, Venise était une cité dynamique et cosmopolite attirant des dizaines de milliers d’immigrants qui venaient s’y installer de façon plus ou moins permanente. Pour pouvoir demeurer dans la lagune, il leur fallait obtenir le « droit d’habiter », un droit qui relevait autant d’une pratique sociale communautaire et tacite que d’un cadre juridique. Cet article explore comment la pratique et le droit se modifièrent au cours du XVI e siècle, dans un contexte spécifique de tensions politiques et économiques. Il analyse ce que signifiait être « vénitien », « habitant » et « étranger » en se plaçant à l’échelle des habitants ordinaires qui peuplaient la ville. Il cherche à établir comment les immigrants étaient identifiés, individuellement et collectivement, lorsqu’ils s’installaient dans la ville afin d’accéder à ces droits, dans le contexte de stabilisation de nouvelles formes d’identification standardisées et enregistrées par écrit, mises en place par le gouvernement vénitien au XVI e siècle.
Étrangers de droits , Français de nation : intégration des migrants dans les corporations de métiers aux Pays-Bas espagnols (XVII e siècle)
Authors: Kervyn Marie
Published: September 2017

Comment l’extranéité est-elle conçue et gérée dans une société frontalière où la présence de migrants est fréquente ? Comment les limites politiques séparant (ou unissant) deux États modernes en construction se reflètent-elles en termes de pratiques sociales ? Afin de proposer des éléments de réponse à ces questions, la présente contribution questionne les droits dont bénéficient les étrangers de nation provenant du royaume de France dans les corporations de métiers de l’espace méridional des Pays-Bas espagnols. Pointant l’importance du concept d’appartenance locale et la malléabilité, voire la relativité, de celui d’extranéité, cette contribution actualise l’historiographie relative aux migrants français au sein de la monarchie hispanique autant que celle consacrée aux corporations des Pays-Bas méridionaux.
À propos des marqueurs vraiment et pas vraiment en antéposition nominale
Authors: Vladimirska Elena
Published: September 2017

Résumé Vraiment et pas vraiment confèrent au N qui les suit un statut que nous nous proposons ici d’expliciter à partir de la sémantique du vrai , qui constitue la base de ces deux mots. Nous distinguerons le cas de la reprise du nom déjà actualisé dans le contexte ( p vraiment p / p pas vraiment p ), et le cas où le nom qui constitue la portée du marqueur apparaît pour la première fois dans le contexte. Nous avançons l’hypothèse que vraiment agit sur le domaine notionnel de N en construisant une occurrence centrée, tout en spécifiant l’adéquation du nom sélectionné pour exprimer ce qui est le cas comme adéquation absolue, sans aucune relativité ni approximation. Quant au marqueur pas vraiment , il n’est pas à traiter comme symétrique de vraiment  : relevant de la frontière du domaine notionnel de N, ce marqueur participe à la construction de différents degrés d’altérité, tout en effectuant une invalidation plus ou moins partielle de l’adéquation du nom à l’état de choses Z.

Published: September 2017

In order to better deal with large data information in computer networks, a large data fusion method based on wireless sensor networks is designed. Based on the analysis of the structure and learning algorithm of RBF neural networks, a heterogeneous RBF neural network information fusion algorithm in wireless sensor networks is presented. The effectiveness of information fusion processing methods is tested by RBF information fusion algorithm. The proposed algorithm is applied to heterogeneous information fusion of cluster heads or sink nodes in wireless sensor networks. The simulation results show the effectiveness of the proposed algorithm.  Based on the above finding, it is concluded that the RBF neural network has good real-time performance and small network delay. In addition, this method can reduce the amount of information transmission and the network conflicts and congestion.
Quality and Safety Traceability System of Aquatic Products Based on Internet of Things
Authors: Xu Xiaohua
Published: September 2017

In order to better detect the quality of aquatic products, a water quality and safety traceability system based on Internet of things has been designed. By analyzing the marine product quality and safety control, a standardized, intelligent and universal marine product quality safety traceability system is proposed based on the Internet of things technology and the characteristics of the seafood industry chain are analyzed. The process about “seedling purchase (seedling propagation) - seafood cultivation - seafood fishing - seafood processing - seafood sales" is selected as the main line, and sensors are used to collect seafood information. The final information is pooled into the seafood traceability data center. Companies can view the seafood traceability data in the traceability system, and consumers can obtain product traceability data by scanning the two-dimensional code of product packaging. The system adopts B/S model and SSH framework to complete system development. The experimental results show that the new system provides powerful technical support for marine product traceability and marine product quality safety management. Based on the above finding, it is concluded that the traceability system has been technically able to effectively improve the product management of marine fishery enterprises through the information management technology. At the same time, it lays a good foundation for the overall upgrading and reform of China's marine fishery industry.

Published: September 2017

Background

The Trans-Theoretical model (TTM) and Theory of Planned Behaviour (TPB) may be promising models for understanding and predicting reduction in the consumption of fast food. The aim of this study was to examine the applicability of the Trans-Theoretical model (TTM) and the additional predictive role of the subjective norms and perceived behavioural control in predicting reduction consumption of fast food in obese Iranian adolescent girls.

Materials and Methods

A cross sectional study design was conducted among twelve randomly selected schools in Sabzevar, Iran from 2015 to 2017. Four hundred eighty five randomly selected students consented to participate in the study. Hierarchical regression models used to predict the role of important variables that can influence the reduction in the consumption of fast food among students. using SPSS version 22.

Results

Variables Perceived behavioural control (r=0.58, P<0.001), Subjective norms (r=0.51, P<0.001), self-efficacy (r=0.49, P<0.001), decisional balance (pros) (r=0.29, P<0.001), decisional balance (cons) (r=0.25, P<0.001), stage of change (r=0.38, P<0.001), were significantly and positively correlated while experiential processes of change (r=0.08, P=0.135) and behavioural processes of change (r=0.09, P=0.145), were not significant.

Conclusions

The study demonstrated that the TTM (except the experiential and behavioural processes of change) focusing on the perceived behavioural control and subjective norms are useful models for reduction in the consumption of fast food.
