Electrostatic Sensor Application for On-Line Monitoring of Wind Turbine Gearboxes
Authors: Mao Huijie , Zuo Hongfu , Wang Han
Published: October 2018

The oil-line electrostatic sensor (OLES) is a new online monitoring technology for wear debris based on the principle of electrostatic induction that has achieved good measurement results under laboratory conditions. However, for practical applications, the utility of the sensor is still unclear. The aim of this work was to investigate in detail the application potential of the electrostatic sensor for wind turbine gearboxes. Firstly, a wear debris recognition method based on the electrostatic sensor with two-probes is proposed. Further, with the wind turbine gearbox bench test, the performance of the electrostatic sensor and the effectiveness of the debris recognition method are comprehensively evaluated. The test demonstrates that the electrostatic sensor is capable of monitoring the debris and indicating the abnormality of the gearbox effectively using the proposed method. Moreover, the test also reveals that the background signal of the electrostatic sensor is related to the oil temperature and oil flow rate, but has no relationship to the working conditions of the gearbox. This research brings the electrostatic sensor closer to practical applications.

Authors: Ramezani Dooraki Amir , Lee Deok-Jin
Published: October 2018

In recent years, machine learning (and as a result artificial intelligence) has experienced considerable progress. As a result, robots in different shapes and with different purposes have found their ways into our everyday life. These robots, which have been developed with the goal of human companionship, are here to help us in our everyday and routine life. These robots are different to the previous family of robots that were used in factories and static environments. These new robots are social robots that need to be able to adapt to our environment by themselves and to learn from their own experiences. In this paper, we contribute to the creation of robots with a high degree of autonomy, which is a must for social robots. We try to create an algorithm capable of autonomous exploration in and adaptation to unknown environments and implement it in a simulated robot. We go further than a simulation and implement our algorithm in a real robot, in which our sensor fusion method is able to overcome real-world noise and perform robust exploration.
Semantic-Enhanced Multi-Dimensional Markov Chains on Semantic Trajectories for Predicting Future Locations
Authors: Karatzoglou Antonios , Köhler Dominik , Beigl Michael
Published: October 2018

In this work, we investigate the performance of Markov Chains with respect to modelling semantic trajectories and predicting future locations. In the first part, we examine whether and to what degree the semantic level of semantic trajectories affects the predictive performance of a spatial Markov model. It can be shown that the choice of the semantic level when describing trajectories has a significant impact on the accuracy of the models. High-level descriptions lead to better results than low-level ones. The second part introduces a multi-dimensional Markov Chain construct that considers, besides locations, additional context information, such as time, day and the users’ activity. While the respective approach is able to outperform our baseline, we could also identify some limitations. These are mainly attributed to its sensitivity towards small-sized training datasets. We attempt to overcome this issue, among others, by adding a semantic similarity analysis component to our model that takes the varying role of locations due each time to the respective purpose of visiting the particular location explicitly into consideration. To capture the aforementioned dynamics, we define an entity, which we refer to as Purpose-of-Visit-Dependent Frame (PoVDF). In the third part of this work, we describe in detail the PoVDF-based approach and we evaluate it against the multi-dimensional Markov Chain model as well as with a semantic trajectory mining and prefix tree based model. Our evaluation shows that the PoVDF-based approach outperforms its competition and lays a solid foundation for further investigation.
Survey on Prominent RFID Authentication Protocols for Passive Tags
Authors: Baashirah Rania , Abuzneid Abdelshakour
Published: October 2018

Radio Frequency Identification (RFID) is one of the leading technologies in the Internet of Things (IoT) to create an efficient and reliable system to securely identify objects in many environments such as business, health, and manufacturing areas. Recent RFID authentication protocols have been proposed to satisfy the security features of RFID communication. In this article, we identify and review some of the most recent and enhanced authentication protocols that mainly focus on the authentication between a reader and a tag. However, the scope of this survey includes only passive tags protocols, due to the large scale of the RFID framework. We examined some of the recent RFID protocols in term of security requirements, computation, and attack resistance. We conclude that only five protocols resist all of the major attacks, while only one protocol satisfies all of the security requirements of the RFID system.
Hyperspectral Remote Sensing Image Classification Based on Maximum Overlap Pooling Convolutional Neural Network
Authors: Li Chenming , Yang Simon X. , Yang Yao , Gao Hongmin , Zhao Jia , Qu Xiaoyu , Wang Yongchang , Yao Dan , Gao Jianbing
Published: October 2018

In a traditional convolutional neural network structure, pooling layers generally use an average pooling method: a non-overlapping pooling. However, this condition results in similarities in the extracted image features, especially for the hyperspectral images of a continuous spectrum, which makes it more difficult to extract image features with differences, and image detail features are easily lost. This result seriously affects the accuracy of image classification. Thus, a new overlapping pooling method is proposed, where maximum pooling is used in an improved convolutional neural network to avoid the fuzziness of average pooling. The step size used is smaller than the size of the pooling kernel to achieve overlapping and coverage between the outputs of the pooling layer. The dataset selected for this experiment was the Indian Pines dataset, collected by the airborne visible/infrared imaging spectrometer (AVIRIS) sensor. Experimental results show that using the improved convolutional neural network for remote sensing image classification can effectively improve the details of the image and obtain a high classification accuracy.
Characterization of the Natural Colloidal TiO2 Background in Soil
Authors: Philippe Allan , Campos Daniel Armando , Guigner Jean-Michel , Buchmann Christian , Diehl Dörte , Schaumann Gabriele E.
Published: October 2018

An increasing amount of TiO2 engineered nanoparticles (TNP) is released into soils and sediments, increasing the need for dedicated detection methods. Titanium is naturally present in soils at concentrations typically much higher than the estimated concentrations for TNP. Therefore, a precise knowledge of this natural background, including the colloidal fraction, is required for developing adapted strategies for detecting TNP. In this study, we characterized the natural colloidal Ti-background by analyzing eight soils with different properties and origins. A combination of X-ray fluorescence analysis and ICP-OES was used for determining the silicate bound fraction, which was a minor fraction for all soils (0–32%). The colloidal fraction obtained by extracting colloids from soil prior to ICP-OES measurements ranged between 0.3% and 7%. Electron microscopy and hydrodynamic chromatography confirmed that Ti in the form of colloids or larger particles was mostly present as TiO2 minerals with a fraction smaller than 100 nm. The size distribution mode of the extracted colloids determined using hydrodynamic chromatography ranged between 80 and 120 nm. The chromatograms suggested a broad size distribution with a significant portion below 100 nm. In addition to these data, we also discuss possible implications of our findings for the method development for detecting TNP in soils.
Institutional Expectations and Students’ Responses to the College Application Essay
Authors: Todorova Ralitsa
Published: October 2018

This paper explores inequality along the path to college through an analysis of college admissions essays and institutional documents that shape admissions expectations in the United States. The research considers how successful applicants from two different universities and students who are the first in their families to go to college compared to those who are not, approach the college essay in relation to the presented institutional expectations. The sample consists of institutional materials from two universities, one a small private university and one a large public institution. Institutional materials also include documents from college preparatory agencies (such as Kaplan and Khan Academy). Thirty-five student essays were collected from the same two universities mentioned above. Through values analysis, a narrative analysis method, I ask how students with less exposure to the culture of college (taken for granted knowledge about college that is passed down from families) perform the college essay genre. Findings show that students with less exposure to the culture of college focus more on challenges and narrate less expression of their “true selves” in their college admissions essays. Findings can help stakeholders create a more equitable college admissions process that more clearly illuminates institutional expectations for students.
Heart Rate Variability Responses to an Undulating Resistance Training Program in Free-Living Conditions: A Case Study in a Collegiate Athlete
Authors: Holmes Clifton J. , Wind Stefanie A. , Esco Michael R.
Published: October 2018

The purpose of this case study was to evaluate the response in heart rate variability via the parasympathetically-mediated metric of the log-transformed root mean square of successive R-R interval differences (lnRMSSD) to weekly variations in total volume-load (TVL) during an 18-week periodized strength training program in a competitive collegiate hockey athlete. The program consisted of three 60–90 min full-body exercise sessions per week with at least 24-h of rest between each session. Daily lnRMSSD measurements were taken immediately after waking using a validated smartphone application and the pulse-wave finger sensor. The weekly lnRMSSD values were calculated as the mean (lnRMSSDMEAN) and the coefficient of variation (lnRMSSDCV). A Pearson’s bivariate correlation of lnRMSSDMEAN and TVL revealed no statistically significant correlation between the two variables; TVL (r = −0.105, p = 0.678). However, significant correlations were found between lnRMSSDCV and both total load (TL) (r = −0.591, p = 0.013) and total volume (TV) (r = 0.765, p < 0.001). Additionally, weekly ratings of perceived exertion (RPE) mean values were statistically significantly correlated to TVL, r = 0.853, p < 0.001. It was concluded that lnRMSSDCV increased or decreased proportionally to an increase or decrease in TVL during the periodized resistance training program with TV being the strongest, independent indicator of these changes.

Authors: Sanz-Quinto Santiago , Brizuela Gabriel , López-Grueso Raúl , Rice Ian , Moya-Ramón Manuel
Published: October 2018

The purpose of this case study was to investigate the influence of a training load (TL), oxygen saturation (SO2) and blood pressure (BP) on mood states in a wheelchair marathoner during (7 weeks at sea level (SL), 5 weeks at 3860 m altitude, 1 week returning to SL). TL was obtained with Foster’s equation while mood states were obtained with the Profile of Mood States Questionnaire (POMS). Furthermore, SO2 and BP were assessed upon wakening. SO2 (%) decreased at altitude, compared to SL (88.31 ± 2.46 vs. 98.52 ± 0.11) and increased until the last week at altitude (92.64 ± 1.12). Systolic pressure (SP) increased at altitude compared to pre-altitude (126.0 ± 5.1 vs. 107.6 ± 4.4 mmhg), and was not different from the last week at altitude. Controlling for SO2 and SP, differences were also observed in fatigue (97.66 ± 18.92 vs. 17.39 ± 13.71) and vigor (73.23 ± 8.62 vs. 26.48 ± 11.89) as a function of altitude. Upon return to SL, fatigue, vigor, SO2 and SP returned to pre values. This case study demonstrated the POMS was sensitive to worsening patterns in fatigue and vigor at altitude through a practical survey approach combined with daily physiological assessment.
Causality between Oil Prices and Tourist Arrivals
Authors: Huang Xu , Silva Emmanuel , Hassani Hossein
Published: October 2018

This paper investigates the causal relationship between oil price and tourist arrivals to further explain the impact of oil price volatility on tourism-related economic activities. The analysis itself considers the time domain, frequency domain, and information theory domain perspectives. Data relating to the US and nine European countries are exploited in this paper with causality tests which include the time domain, frequency domain, and Convergent Cross Mapping (CCM). The CCM approach is nonparametric and therefore not restricted by assumptions. We contribute to existing research through the successful and introductory application of an advanced method and via the uncovering of significant causal links from oil prices to tourist arrivals.
Evaluation of Progressive Collapse Resistance of Steel Moment Frames Designed with Different Connection Details Using Energy-Based Approximate Analysis
Authors: Lee Sang-Yun , Noh Sam-Young , Lee Dongkeun
Published: October 2018

This study evaluates the progressive collapse resistance performance of steel moment frames, individually designed with different connection details. Welded unreinforced flange-bolted web (WUF-B) and reduced beam section (RBS) connections are selected and applied to ordinary moment frames designed as per the Korean Building Code (KBC) 2016. The 3-D steel frame systems are modeled using reduced models of 1-D and 2-D elements for beams, columns, connections, and composite slabs. Comparisons between the analyzed results of the reduced models and the experimental results are presented to verify the applicability of the models. Nonlinear static analyses of two prototype buildings with different connection details are conducted using the reduced models, and an energy-based approximate analysis is used to account for the dynamic effects associated with sudden column loss. The assessment on the structures was based on structural robustness and sensitivity methods using the alternative path method suggested in General Services Administration (GSA) 2003, in which column removal scenarios were performed and the bearing capacity of the initial structure with an undamaged column was calculated under gravity loads. According to the analytical results, the two prototype buildings satisfied the chord rotation criterion of GSA 2003. These results were expected since the composite slabs designed to withstand more than 3.3 times the required capacity had a significant effect on the stiffness of the entire structure. The RBS connections were found to be 14% less sensitive to progressive collapse compared to the WUF-B ones.
Ma Kahana ka ‘Ike: Lessons for Community-Based Fisheries Management
Authors: Montgomery Monica , Vaughan Mehana
Published: October 2018

Indigenous and place-based communities worldwide have self-organized to develop effective local-level institutions to conserve biocultural diversity. How communities maintain and adapt these institutions over time offers lessons for fostering more balanced human–environment relationships—an increasingly critical need as centralized governance systems struggle to manage declining fisheries. In this study, we focus on one long-enduring case of local level fisheries management, in Kahana, on the most populated Hawaiian island of O‘ahu. We used a mixed-methods approach including in-depth interviews, archival research, and participation in community gatherings to understand how relationships with place and local governance have endured despite changes in land and sea tenure, and what lessons this case offers for other communities engaged in restoring local-level governance. We detail the changing role of konohiki (head fishermen) in modern times (1850–1965) when they were managing local fisheries, not just for local subsistence but for larger commercial harvests. We also highlight ways in which families are reclaiming their role as caretakers following decades of state mismanagement. Considerations for fisheries co-management emerging from this research include the importance of (1) understanding historical contexts for enhancing institutional fit, (2) enduring community leadership, (3) balancing rights and responsibilities, and (4) fostering community ability to manage coastal resources through both formal and informal processes.
Analyzing the Long-Term Service Life of MEP Using the Probabilistic Approach in Residential Buildings
Authors: Lee Sanghyo , Ahn Yonghan
Published: October 2018

Establishing an effective long-term maintenance plan is essential to ensure the sustainability of a building. Among the various components of a building, the mechanical, electrical, and plumbing (MEP) components are complexly affected by various parameters, such as quality and user pattern, with respect to the service life. Besides, these components are replaced at different points in time, which becomes one of the main risks when establishing a maintenance plan for the building. Therefore, it is very important to consider the uncertainty in calculating the service lives of MEP components in a systematic and reasonable way. This study aims to systemize the MEP components of residential buildings and analyze their service life patterns using a probabilistic approach for long-term maintenance planning. The analysis was performed on 54,318 maintenance cases from 1998 to 2017 at 65 twenty-five-year-old rental apartment buildings in South Korea. Before performing the analysis, a service life matrix was established by classifying the MEP components into 12 types and setting the service life time at 6–25 years. Then, the service life distribution was derived for each MEP component. The probabilistic approach can provide information for rational maintenance decision-making regarding each MEP component as well as basic service life settings. Since the performance of the MEP components deteriorates due to various reasons, de facto uncertainty exists in the service life of each component; thus, the probabilistic approach can serve as an important decision-making method. If probabilistic methods are developed by acquiring the cost data in addition to the frequency of maintenance activity used in this study, a more effective long-term maintenance plan can be established.

Authors: Piccarozzi Michela , Aquilani Barbara , Gatti Corrado
Published: October 2018

Recent developments in production processes and their automation have led to the definition of the Fourth Industrial Revolution, commonly known as “Industry 4.0”. Industry 4.0 is a very broad domain that includes: production processes, efficiency, data management, relationship with consumers, competitiveness, and much more. At the same time, obviously, Industry 4.0 has become a new theme for management scholars and business economics disciplines and a number of contributions covering various issues and aspects have been published. However, a systematic formulation of all these contributions is still lacking in management literature. Therefore, the aim of the paper is to analyze and classify the main contributions published on the topic of Industry 4.0 in management literature, seeking to give it a unique definition, discover the gaps still remaining in literature and outline future avenues of research in this domain. A systematic review of the literature of the major academic and research databases has been used as methodology to achieve the aim of the paper. This work contributes theoretically to the development of literature on Industry 4.0 and from a managerial perspective it could support entrepreneurs in better understanding the implications and fields of application of the Fourth Industrial Revolution as well as the interplay among them.
Whose Agency Counts in Land Use Decision-Making in Myanmar? A Comparative Analysis of Three Cases in Tanintharyi Region
Authors: Lundsgaard-Hansen Lara , Schneider Flurina , Zaehringer Julie , Oberlack Christoph , Myint Win , Messerli Peter
Published: October 2018

Myanmar has experienced profound transformations of land use and land governance, often at the expense of smallholders. Empirical evidence on the agency of actors included and excluded in land use decision-making remains scarce. This study analyses who influences land use decision-making, how they do this, and under what circumstances smallholders are included. Comparing three land use trajectories in southern Myanmar, we analysed actors’ agency—conceived as the meanings and means behind (re)actions—in land use decision-making using data from focus groups and interviews. Results showed that uneven distribution of means can lead to unequal decision-making power, enabling actors with more means to exclude those with less means: smallholders. However, this only applies in the case of top-down interventions with mutually exclusive actor interests regarding use of the same land. Where interests are compatible or a mediator supports smallholders in negotiations, actors are likely to develop a collaboration despite unequal means, leading to smallholders’ inclusion in decision-making. Transformation of current land governance towards sustainable development could be promoted by providing mediators to actors with few means, ensuring equal access for all to formal land tenure, engaging with brokers in the land governance network, and improving access to knowledge and financial capital for actors with few means.
Methane, Nitrous Oxide and Ammonia Emissions from Livestock Farming in the Red River Delta, Vietnam: An Inventory and Projection for 2000–2030
Authors: Truong An Ha , Kim Minh Thuy , Nguyen Thi Thu , Nguyen Ngoc Tung , Nguyen Quang Trung
Published: October 2018

Livestock farming is a major source of greenhouse gas and ammonia emissions. In this study, we estimate methane, nitrous oxide and ammonia emission from livestock sector in the Red River Delta region from 2000 to 2015 and provide a projection to 2030 using IPCC 2006 methodologies with the integration of local emission factors and provincial statistic livestock database. Methane, nitrous oxide and ammonia emissions from livestock farming in the Red River Delta in 2030 are estimated at 132 kt, 8.3 kt and 34.2 kt, respectively. Total global warming potential is estimated at 5.9 MtCO2eq in 2030 and accounts for 33% of projected greenhouse gas emissions from livestock in Vietnam. Pig farming is responsible for half of both greenhouse gases and ammonia emissions in the Red River Delta region. Cattle is another major livestock responsible for greenhouse gas emissions and poultry is one that is responsible for ammonia emissions. Hanoi contributes for the largest emissions in the region in 2015 but will be surpassed by other provinces in Vietnam by 2030.
On Approximation of Any Ordered Fuzzy Number by A Trapezoidal Ordered Fuzzy Number
Authors: Piasecki Krzysztof , Łyczkowska-Hanćkowiak Anna
Published: October 2018

In this paper, the model of imprecise quantity information is an ordered fuzzy number. The purpose of our study is to propose some methods of approximating any ordered fuzzy number using a trapezoidal ordered fuzzy number. The information ambiguity is evaluated by means of an energy measure. The information indistinctness is evaluated by Kosko’s entropy measure. We discuss the problem of approximation of an arbitrary ordered fuzzy number by the nearest trapezoidal ordered fuzzy number. This way, we can simplify arithmetical operations on the linear space of ordered fuzzy numbers. The set of feasible trapezoidal ordered numbers is limited by the combination of the following conditions: invariance of energy measure, invariance of entropy measure, and invariance of information support. Evaluating the influence of individual limits combinations on the utility of given approximations, two combinations of those restraints, recommended for use, were chosen. It was also indicated that one of the recommended approximation problems can be used only for ordered fuzzy numbers characterized by a low level of entropy. The obtained results are currently used in such multi-criterial decision making models as financial portfolio management, evaluation of negotiations offers, the fuzzy TOPSIS model, and the fuzzy SAW model.
Complexity, Regularity and Non-Linear Behavior in Human Eye Movements: Analyzing the Dynamics of Gaze in Virtual Sailing Programs
Authors: Menayo Ruperto , Manzanares Aarón , Segado Francisco
Published: October 2018

The non-linear analysis of the behavior of biological signals in humans is studied from different scientific disciplines. The aim of this study was to analyze the possible non-linear behavior present in eye movements during eye-tracking tasks in simulated sailing. Thirty young sailors were selected. Fuzzy entropy and detrended fluctuation analyses were applied to quantify the regularity and complexity of eye movements. The results show that neither experience nor ranking affect the regularity or the complexity of eye movement positions or velocities. Younger age is related to more regular visual behavior. At younger ages, eye positions present more complex behavior. Eye positions show more complex behavior than eye velocities. This complexity would allow for a more functional exploration of the environment by sailors. Eye movement velocity presents the greatest irregularity, with significantly higher values than eye movement position. This irregularity would facilitate the visual perception of the environment. All these findings could be related to the sailors’ functional behavior, based on complexity and stability, which has been associated with the ability of human beings to adapt to the environment.
Advanced Classification of Coffee Beans with Fatty Acids Profiling to Block Information Loss
Authors: Hung Ying-Che , Chen Ping , Chen Liang-Yü
Published: October 2018

Classification is a kernel process in the standardization, grading, and sensory aspects of coffee industries. The chemometric data of fatty acids and crude fat are used to characterize the varieties of coffee. Two category classifiers were used to distinguish the species and roasting degree of coffee beans. However, the fatty acid profiling with normalized data gave a bad discriminant result in the classification study with mixed dimensions in species and roasted degree. The result of the predictive model is in conflict with the context of human cognition, since roasted coffee beans are easily visually distinguished from green coffee beans. By exploring the effects of error analysis and information processing technologies, the lost information was identified as a bias–variance tradeoff derived from the percentile normalization. The roasting degree as extensive information was attenuated by the percentile normalization, but the cultivars as intensive information were enhanced. An informational spiking technique is proposed to patch the dataset and block the information loss. The identified blocking of informational loss could be available for multidimensional classification systems based on the chemometric data.
Relationship between the Paradox of Enrichment and the Dynamics of Persistence and Extinction in Prey-Predator Systems
Authors: Alebraheem Jawdat
Published: October 2018

The paradox of the enrichment phenomenon, considered one of the main counterintuitive observations in ecology, likely destabilizes predator–prey dynamics by increasing the nutrition of the prey. We use two systems to study the occurrence of the paradox of enrichment: The prey–predator system and the one prey, two predators system, with Holling type I and type II functional and numerical responses. We introduce a new approach that involves the connection between the occurrence of the enrichment paradox and persistence and extinction dynamics. We apply two main analytical techniques to study the persistence and extinction dynamics of two and three trophics, respectively. The linearity and nonlinearity of functional and numerical responses plays important roles in the occurrence of the paradox of enrichment. We derive the persistence and extinction conditions through the carrying capacity parameter, and perform some numerical simulations to demonstrate the effects of the paradox of enrichment when increasing carrying capacity.
Mason-Pfizer Monkey Virus Envelope Glycoprotein Cycling and Its Vesicular Co-Transport with Immature Particles
Authors: Prokšová Petra Grznárová , Lipov Jan , Zelenka Jaroslav , Hunter Eric , Langerová Hana , Rumlová Michaela , Ruml Tomáš
Published: October 2018

The envelope glycoprotein (Env) plays a crucial role in the retroviral life cycle by mediating primary interactions with the host cell. As described previously and expanded on in this paper, Env mediates the trafficking of immature Mason-Pfizer monkey virus (M-PMV) particles to the plasma membrane (PM). Using a panel of labeled RabGTPases as endosomal markers, we identified Env mostly in Rab7a- and Rab9a-positive endosomes. Based on an analysis of the transport of recombinant fluorescently labeled M-PMV Gag and Env proteins, we propose a putative mechanism of the intracellular trafficking of M-PMV Env and immature particles. According to this model, a portion of Env is targeted from the trans-Golgi network (TGN) to Rab7a-positive endosomes. It is then transported to Rab9a-positive endosomes and back to the TGN. It is at the Rab9a vesicles where the immature particles may anchor to the membranes of the Env-containing vesicles, preventing Env recycling to the TGN. These Gag-associated vesicles are then transported to the plasma membrane.
THE MECHANISMS OF TECHNOLOGICAL INNOVATION IN SMES: A BAYESIAN NETWORK ANALYSIS OF EU REGIONAL POLICY IMPACT ON POLISH FIRMS
Authors: Florio Massimo , Parteka Aleksandra , Sirtori Emanuela
Published: October 2018

We study the underlying mechanisms of technological innovation in SMEs in the context of ex-post evaluation of European Union’s regional policy. Our aim is to explain the observed change in firms’ innovativeness after receiving EU support for technological investment. To do so, we take an approach that is novel in innovation studies: a Bayesian Network Analysis to assess the effectiveness of EU policy instrument for technological innovation and to determine the mechanisms by which the policy works within firms. Our data draw from a unique survey of 200 Polish firms that received “Technological Credit” during the 2007−2013 programming period. First, we confirm the short-term positive impact of the EU innovation policy (i.e. a wider range of products/services offered, increased sales and exports). More importantly, we determine the causal chain between economically quantifiable outcomes and behavioural change in the firm, which is an important node in the network of effects generated. We find that only the financially sounder and more internationalised firms managed to take advantage of the policy. These findings suggest that programmes based on technological credits are not well suited to foster innovation in more fragile and domestically oriented SMEs, which may require different policy instruments.

Discordances sur la performance des pôles technologiques : efficacité ou effectivité ? Cas de deux pôles technologiques en Tunisie
Authors: Chebil Anissa , Aliouat Boualem , Ben Kahla Karim
Published: October 2018

Le débat sur la performance des pôles technologiques au Maghreb s’est essentiellement concentré sur leur efficacité et leur efficience objectives, alors que le degré de satisfaction perçue des entreprises a été peu traité. Notre recherche analyse cette effectivité des pôles à partir d’un questionnaire portant sur 39 entreprises de deux pôles technologiques tunisiens (Elghazala à Tunis et Mecatronic à Sousse). Nos résultats mettent en exergue une situation paradoxale où les pôles présentent de réels potentiels de ressources, mais de faibles capacités de dynamique d’acteurs/projets. Nous constatons en effet un déficit d’organisation de la proximité relationnelle et de soutien des pôles en termes d’incitation des entreprises à participer aux projets collaboratifs. Notre travail recommande aux entrepreneurs institutionnels de favoriser par des dispositifs appropriés de dynamique d’acteurs/projets, la « relationalité » effective et pas seulement la mise en proximité.

La prévention de l’engagement des jeunes dans les trafics, un nouveau champ du travail social ?
Authors: Benso Vincent
Published: October 2018

Loin des présupposés qui entourent le trafic de drogues (argent facile, belles voitures...), la recherche en sciences sociales dresse un tableau peu reluisant de la vie des trafiquants : bas revenus et risques élevés... Autant de leviers de prévention possibles pour des acteurs de terrain confrontés à l’attraction qu’exercent les réseaux sur les jeunes.
La consommation à risque de cannabis à l’adolescence : une « huile » aux rouages de la subjectivation ?
Authors: Gravrand Thibaud
Published: October 2018

Sous l’effet de la puberté, l’adolescence réactualise et suractive l’élaboration du processus de séparation et d’individuation, amenant à redynamiser le narcissisme et la relation d’objet, à requestionner le rapport à soi, à l’autre et au monde. Face à ce processus de subjectivation, l’usage « à risque » de cannabis, à travers différentes caractéristiques positives qu’il faut reconnaître pour comprendre cette propension des jeunes à consommer, semble se présenter comme une certaine réponse à différents niveaux à cette réorganisation psychique. Objet sensoriel et affectif, pansement psychique par ses vertus anxiolytiques et antidépresseurs, objet transitionnel et transactionnel, la consommation de cannabis, lorsqu’elle reste festive et irrégulière, semble tenter de contribuer à l’élaboration de cette identité en construction.
Nom et ambition
Authors: Kaltenbeck Franz
Published: October 2018

L’ambition ne résulte pas toujours de constellations heureuses. Parfois, elle doit être engendrée en désespoir de cause. Être en accord avec son nom n’est pas évident pour tous, et tous n’ont pas la chance de « se faire un nom » en réparant le rapport à leur nom propre. J’ai voulu montrer comment deux analysants, qui avaient en commun la double ambition d’acquérir le titre de « professeur » et de transmettre un savoir, ont essayé de suppléer à une difficulté liée à leur nom. Alors que l’un, qui souffrait d’une névrose de destinée, ne se sentait pas à la hauteur et ratait systématiquement l’agrégation, l’autre, qui était insatisfait du nom qu’il avait reçu de son beau-père, n’a jamais osé se présenter à un concours de l’Éducation nationale : la rétention, par sa mère, du savoir qu’elle détenait sur sa naissance l’a empêché d’acquérir le savoir qu’on lui demandait au concours. La difficulté de l’analyse consiste alors dans la tâche de donner à l’ambitieux un aperçu du réel de son désir, mais sans insulter son ambition.
Les détours d’un autiste
Authors: Fleury Emmanuel
Published: October 2018

Isaac se livre à l’écholalie avec insistance. C’est ce qu’il oppose aux ambitions de l’autre. à l’éducateur qui lui explique que « le lion rugit », à grand renfort de supports visuels, il répond : « lionrugit ». Son écholalie répond à l’ambition que l’autre lui manifeste, analogue, dans ce cas, au désir de l’Autre. Si un enfant répète une question que vous lui posez, en écho, c’est qu’il interroge le signifiant dans ce qu’il peut avoir d’équivoque. Pour Isaac, il s’est avéré qu’il s’agissait d’une ébauche de séries et de listes qui lui ont permis d’établir son rapport à l’Autre, empruntant un long détour. Cette visée consistant à nouer la jouissance au signifiant, les analystes se sont donné pour tâche de l’encourager. Les enfants nous incitent à suivre cette voie de ce qui cause notre angoisse et de tenter de le cerner. Et c’est une voie divergente.
L’inquiétante étrangeté de l’étranger
Authors: Yvan Frédéric
Published: October 2018

Freud et Simmel ont en commun d’inaugurer chacun un nouvel objet d’étude – l’étranger et l’étrangeté – et de fonder respectivement une réflexion spécifique s’y rapportant ; ils partagent plus précisément l’effort de procéder par une détermination et une élucidation topologique de leur objet. C’est à cette perspective que nous nous intéresserons en nous attachant à croiser la réflexion de ces deux penseurs.
Quand l’altérité devient virale : exemple du cyberbullying
Authors: Gozlan Angélique
Published: October 2018

L’utilisation des réseaux sociaux par les adolescents compte aujourd’hui parmi leurs usages quotidiens. Pour être présent sur la toile, il est nécessaire que s’opère un dévoilement de soi, passage de l’intime à la sphère sociale, que l’auteure nomme « désintimité ». Un des destins de la désintimité implique la perte irrémédiable de son intimité dans l’espace virtuel, point de départ du harcèlement virtuel. Plus de 15 % des enfants et adolescents utilisant Internet connaissent l’intimidation en ligne. Alors que les recherches actuelles cherchent à comprendre à la fois comment réagissent ou non les spectateurs du cyberbullying et quels sont les facteurs psychologiques, d’usage, d’outils qui favorisent ce phénomène, l’auteure souhaite aborder dans cet article l’aspect processuel du harcèlement virtuel. Quels sont les processus sous-jacents au harcèlement virtuel ? En ce sens, les notions de désintimité, d’altérité virale, de groupalité virtuelle associées à la désinhibition seront abordées afin d’approcher les enjeux du harcèlement virtuel.
Donatien, l’affranchi
Authors: Verstraet Antoine
Published: October 2018

Donatien est un jeune homme qui a la certitude que certains hommes qu’il croise dans la rue appartiennent à l’organisation terroriste Al Qaïda. Ils ne le menacent pas directement mais ils enlèvent d’autres hommes et tentent d’empoisonner la population. Alors, Donatien « a l’œil ». En effet « à force de pratique », il a développé une « perception fine » : il entend et voit mieux que tous les autres ; ce qui lui permet de tenter de contrecarrer ces funestes projets.

Blaise Ndala revient sur le malaise qu’il a ressenti, à la fin de ses études, à la lecture du Cœur des ténèbres. Ce malaise perdure : pourquoi Conrad a-t-il choisi le bassin du Congo pour planter le décor de sa nouvelle ? Pourquoi l’homme noir devient-il, sous sa plume, un pantin moitié muet et moitié sauvage ?
The Effects of Brand Cognition Process in Automobile Marketing in the Developed Countries
Authors: Dutta Gautam , Dutta Abhishek
Published: October 2018

The developed country consumers actually build up three types of barriers while acknowledging inconspicuous automobile brands from developing countries which almost act linearly in three successive phases of brand cognition. These barriers create three types of quantifiable psychological distances. This article, in the backdrop of an Indian automobile brand's marketing endeavor in USA, details the underlying psychological reasons towards ignoring inconspicuous foreign brands of developing countries and quantifies psychological distances for the Indian automobile brand understudy. This article also shows a way to bring the theoretical understanding of COO based brand cognition process to a practical level which the marketing managers of developing countries can use while extending their brands to the developed country markets.
Model for Multiple Attribute Decision Making Based on Picture 2-Tuple Linguistic Power Aggregation Operators
Authors: Wei Guiwu
Published: October 2018

In this article, the authors investigate the multiple attribute decision making problems with picture 2-tuple linguistic information. The utilized power average and power geometric operations used to develop some picture 2-tuple linguistic power aggregation operators: picture 2-tuple linguistic power weighted average (P2TLPWA) operator, picture 2-tuple linguistic power weighted geometric (P2TLPWG) operator, picture 2-tuple linguistic power ordered weighted average (P2TLPOWA) operator, picture 2-tuple linguistic power ordered weighted geometric (P2TLPOWG) operator, picture 2-tuple linguistic power hybrid average (P2TLPHA) operator and picture 2-tuple linguistic power hybrid geometric (P2TLPHG) operator. The prominent characteristic of these proposed operators is studied. This article has utilized these operators to develop some approaches to solve the picture 2-tuple linguistic multiple attribute decision making problems. Finally, a practical example for enterprise resource planning (ERP) system selection is given to verify the developed approach and to demonstrate its practicality and effectiveness.

Authors: Laredj Adnane , Rouba Baroudi , Duvallet Claude
Published: October 2018

Group decision support system (GDSS) can be appropriate if used in e-maintenance decision-related meeting as a medium for them to share, extract and analyze the information, and making decision. In addition, in any GDSS, facilitation process is capital, since a facilitator makes meetings more productive and efficient, by managing the content. However, the election of the expert's group facilitator has been only based on networks quality between the expert and the breakdown site, while, according to case study and maintenance expert interviews, facilitator election consists in identifying and choosing alternatives to find the best solution based on different factors. Therefore, in this article, to formalize the problem of facilitator election using multicriteria decision aid concepts, knowing that the difficult point is the multiplicity of the criteria set for judging the alternatives in the group coordination election problem.
Superposed Redundancy Approach for Building Reliable Communication in Multi-Bus Heterogeneous Systems
Authors: Arar Chafik
Published: October 2018

In this article, the author uses a new variant of passive redundancy, which allows for a fictitious dual assignment by simultaneously scheduling two backup copies that overlap on the same communication bus at a given time. The proposed reliable fault tolerant greedy list scheduling algorithm is based on a superposed backup copy. This scheduling algorithm is considering up to n communication buses faults, caused by hardware faults and compensated by software redundancy solutions. it allows a reliable communication and efficient use of buses. In the experiments, the proposed methods are evaluated in terms of data scheduling length for a set of DSP benchmarks from the DSPstone.
