Authors: Etterson Julie R. , Toczydlowski Rachel H. , Winkler Katharine J. , Kirschbaum Jessica A. , McAulay Tim S.
Published: October 2015

PREMISE OF THE STUDY:

Although our awareness of ploidy diversity has expanded with the application of flow cytometry, we still know little about the extent to which cytotypes within mixed‐ploidy populations are genetically differentiated across environmental gradients.

METHODS:

To address this issue, we reared 14 populations of Solidago altissima spanning the prairie–forest ecotone in Minnesota in a common garden with a watering treatment. We assessed ploidy frequencies and measured survival, flowering phenology, and plant architectural traits for 4 years.

KEY RESULTS:

All populations harbored multiple cytotypes; prairie populations were dominated by tetraploids, forest populations by hexaploids. Diploids and polyploids differed significantly for 84% of the traits. Beyond average differences, the slope of trait values covaried with latitude and longitude, but this relationship was stronger for diploids than the other two polyploid cytotypes as indicated by numerous ploidy × latitude and ploidy × longitude interactions. For example, the timing of flowering of the cytotypes overlapped in populations sampled from the northeastern hemiboreal forest but differed significantly between cytotypes sampled from populations in the southwestern prairie. The watering treatments had weak effects, and there were no ploidy differences for phenotypic plasticity.

CONCLUSIONS:

Our data show that diploids have diverged genetically to a greater extent than polyploids along the environmental clines sampled in this study. Moreover, different environments favor phenotypic convergence over divergence among cytotypes for some traits. Differences in ploidy frequency and phenotypic divergence among cytotypes across gradients of temperature and precipitation are important considerations for restoration in an age of climate change.
Nanostructured superhydrophobic films synthesized by electrodeposition of fluorinated polyindoles
Authors: Ramos Chagas Gabriela , Darmanin Thierry , Guittard Frédéric
Published: October 2015

Materials with bioinspired superhydrophobic properties are highly desirable for many potential applications. Here, nine novel monomers derived from indole are synthesized to obtain these properties by electropolymerization. These monomers differ by the length (C4F9, C6F13 and C8F17) and the position (4-, 5- and 6-position of indole) of the perfluorinated substituent. Polymeric films were obtained with C4F9 and C6F13 chains and differences in the surface morphology depend especially on the substituent position. The polyindoles exhibited hydrophobic and superhydrophobic properties even with a very low roughness. The best results are obtained with PIndole-6-F6 for which superhydrophobic and highly oleophobic properties are obtained due to the presence of spherical nanoparticles and low surface energy compounds.

Published: October 2015

We report herein a two or three step synthesis of fluorinated π-conjugated oligomers through iterative C–H bond arylations. Palladium-catalyzed desulfitative arylation of heteroarenes allowed in a first step the synthesis of fluoroaryl-heteroarene units in high yields. Then, the next steps involve direct arylation with aryl bromides catalyzed by PdCl(C3H5)(dppb) to afford triad or tetrad heteroaromatic compounds via regioselective activation of C(sp2)–H bonds.

Parmi les patients auteurs de violences sexuelles que nous accueillons dans notre dispositif thérapeutique de psychodrame, certains sont atteints d’un handicap physique. Pour ces sujets, le vécu d’humiliation, systématiquement observé dans ces problématiques, apparaît de manière singulière. Dans cette contribution, nous chercherons à comprendre les actes de violences sexuelles d’un de ces patients à la lumière de l’impact traumatique des humiliations liées à son handicap sur son organisation psychique, en particulier au regard de la ligne de tension entre activité et passivité ouvrant à la question du féminin. Enfin nous conclurons autour de la mobilisation exercée par le dispositif sur ces dimensions.
Public Restorative Justice: The Participatory Democratic Dimensions of Institutional Reform
Authors: Dzur Albert W.
Published: October 2015

Cet article analyse la manière dont la sensibilisation des citoyens aux questions de justice restaurative peut être envisagée d’un point de vue à la fois normatif et pratique. Les exemples étudiés sont ceux des programmes éducationnels, des organisations communautaires non gouvernementales et des prisons qui cherchent à produire un effet public transformatif à travers un engagement plus fort des citoyens ordinaires dans les pratiques de justice. J’analyse les actions que des praticiens innovateurs et animés par un esprit de réforme ont menées pour encourager l’engagement de la communauté et le dialogue sur les pratiques pénales, les ressources disponibles pour appuyer cet engagement et les obstacles qui empêchent qu’on obtienne des effets plus considérables. Il y a un récit normatif à écrire sur le développement des principales dimensions démocratiques de la justice restaurative, récit qui doit occuper une position plus centrale dans la théorie et la pratique du mouvement restauratif. Les efforts innovateurs discutés montrent qu’on doit réfléchir de manière plus radicale au contexte civique dans lequel les programmes de justice restaurative se trouvent incorporés.
Les dynamiques de transfert des idées restauratives
Authors: Faget Jacques
Published: October 2015

La question de la circulation des normes, des modèles politiques et des idées est de plus en plus souvent abordée par les recherches en politiques publiques, en relations internationales, en politique comparée ou en sociologie. Mais elle n’est qu’effleurée dans le champ des idées restauratives malgré leur dissémination progressive dans le monde. Le temps me semble donc venu d’ouvrir une réflexion sur les dynamiques de transfert de cette philosophie restaurative. Je présenterai dans un premier temps la matrice théorique qui a servi de boussole à mon travail. Je procèderai ensuite à une analyse plus territorialisée des flux et des reflux qui ont marqué la circulation du corpus restauratif en France.
Revisiting the Debate on Inequality and Economic Development
Authors: Bourguignon François
Published: October 2015

Cet article réexamine de façon sélective l’abondante littérature économique des 20 dernières années sur la relation entre inégalité et développement. Son principal argument porte sur la distinction nécessaire, et souvent négligée, entre « inégalité des revenus », ou des résultats, et « inégalité des chances » comme frein au développement. Les justifications théoriques d’une relation négative entre développement et inégalité suggèrent que ce n’est pas l’inégalité des résultats, revenu ou consommation, qui est un frein au développement. Ce sont d’autres dimensions, plus fondamentales, de l’inégalités économique et sociale, comme les différences dans les familles ou les milieux sociaux d’origine, dans l’accès à l’éducation, aux soins de santé, au crédit, à la sécurité ou à la justice, ou encore la discriminations à l’égard de certains groupes ethniques ou des femmes. Il se trouve que l’inégalité des revenus sur laquelle se concentre presqu’exclusivement la littérature empirique sur inégalité et développement n’est qu’un marqueur très imparfait de cette définition plus générale de l’inégalité, qui correspond à l’« inégalité des chances ». Mais en même temps, et de façon paradoxale, corriger ces dimensions de l’inégalité requiert le plus souvent des politiques impliquant une certaine redistribution des revenus, bien que l’inégalité des revenus soit plutôt une conséquence que la principale cause des inégalités qui compromettent le développement.
Thermophysical and mechanical properties of Bisphenol A epoxy resin filled with multiwalled carbon nanotubes
Authors: Borisova Anna , Glaskova-Kuzmina Tatiana , Aniskevich Andrey
Published: October 2015

Dilatometric tests, thermal mechanical analysis (TMA), quasistatic tensile tests, hydrostatic weighting, and scanning electron microscopy (SEM) were performed on the multiwalled carbon nanotube (MWCNT)/epoxy nanocomposite (NC) with different filler content (c = 0–3.8% wt.) in order to determine the influence of MWCNT content on the thermophysical and mechanical properties of NC. The experimental results show the physical properties versus the nanofiller content and the existence of the optimal MWCNT content (1% wt.) in epoxy resin that maximally improves the thermophysical properties of NC in comparison with unfilled epoxy. Thus, NC with 1% wt. filler content shows the maximal decrease of thermal expansion coefficient by 68%, the maximal increase of glass transition temperature and tensile strength by 23 °C and 18%, respectively. Comparing the results it can be seen that after exceeding the defined optimal filler content over 1% wt. the investigated properties get worse. The correlation between the investigated mechanical and thermophysical properties is estimated and reported.

Fuzzy Nominal Classification using Bipolar Analysis
Authors: Tchangani Ayeley P.
Published: October 2015

The process of assigning objects (candidates, projects, decisions, options, etc.) characterized by multiple attributes or criteria to predefined classes characterized by entrance conditions or constraints constitutes a subclass of multi-criteria decision making problems known as nominal or non-ordered classification problems as opposed to ordinal classification. In practice, class entrance conditions are not perfectly defined; they are rather fuzzily defined so that classification procedures must be design up to some uncertainty degree (doubt, indecision, imprecision, etc.). The purpose of this chapter is to expose recent advances related to this issue with particular highlights on bipolar analysis that consists in considering for a couple of object and class, two measures: classifiability measure that measures to what extent the former object can be considered for inclusion in the later class and rejectability measure, a degree that measures the extent to which one should avoid including this object into that class rendering final choice flexible and robust as many classes may be qualified for inclusion of an object. This apparent theoretical subject finds applications in almost any socio-economic domain and particularly in digital marketing. An application to supply chain management, where a certain number of potential suppliers of a company are to be classified in a number of classes in order to apply the appropriate strategic treatment to them, will be considered for illustration purpose.

Authors: Samantra Chitrasen , Datta Saurav , Mahapatra Siba Sankar
Published: October 2015

Recently competition in the global marketplace has stimulated immense attention being paid by the enterprises towards securing highest quality, cost effective components and materials, consistently delivered on time. This objective can only be achieved by establishing long term, close working relationships with suppliers, who adopt a proper quality philosophy. Supplier Quality Assurance is the confidence in a supplier's ability to deliver a commodity or service towards satisfying customer's needs. Supplier Quality Assurance can be achieved through interactive relationship between the customer and the supplier; it aims at ensuring the product's ‘suitably fit' to the customer's requirements with little or no adjustment or inspection. In the present context, the study develops a decision-making framework to assure as well as to assess suppliers' existing quality philosophy, current policy and related practices. An Interval-Valued Fuzzy Set (IVFS) theory has been adopted to develop such an evaluation model.

Authors: Navitskaya Katsiaryna
Published: October 2015

The article presents the possibility of using multi-criteria fuzzy analysis for assessing the regional competitiveness. This estimation can be used for place marketing strategy development and based on results of socio-economic development. The proposed approach is characterized by comparative estimation, when the level of development of one region is determined by the development of other areas. The final evaluation is the level of the cluster which the object being analyzed belongs. This allows ignoring minor fluctuations in total indexes. The results of robust and fuzzy groups of regions are analyzed. This grouping is characterized by similar levels of development and helps to define the directions of further development of the regions.

Published: October 2015

Fractionated Spacecraft is a concept which transforms a traditional monolithic spacecraft into a network of elements where a free-flying payload module is supported by nearby free-flying infrastructure modules. In this paper, we propose a novel concept named as Payload-Distributed GEO Communication Satellite System (PD-GEO) which divides the traditional GEO communication satellite into several modules. Those modules can be reconfigured, added, or exchanged independently from the others, and be reused over several missions. Then, for the purpose of reliable and high-efficient data transmission in this system, an opportunistic network coding based cooperative information exchange (ONC2IE) scheme was presented. Qualitative analysis and extensive simulations demonstrate the effectiveness and efficiency of ONC2IE.
A Novel Approach for PAPR Reduction of NC-OFDM System
Authors: Fang Hui
Published: October 2015

Although Non-continuous OFDM (NC-OFDM) has the unique advantage of eliminating interference to authorized user in cognitive radio context, it also confronts a difficulty of reducing peak to average power ratio (PAPR) like other OFDM techniques. In this paper, carrier interferometry is proposed to apply in NC-OFDM system in order to reduce its PAPR using the construction feature of CI code itself. The coding principle of CI code is analyzed at first. Then NC-OFDM base-band system based on carrier interferometry (CI/NC-OFDM) is modeled. Theoretical analysis and matlab simulation results indicate that CI code can bring 3 dB lower PAPR reference with the same probability of exceeding some PAPR reference, compared with traditional NC-OFDM system. This method is effective and feasible and gets better BER performance as well.
A Novel Decoupled LOS Rate Estimator for Terminal Guidance
Authors: Zhai Qing Lin , Lu Da Wei , Zhang Jun
Published: October 2015

An novel decoupled estimation algorithm based on kalman filter is presented to solve the line-of-sight (LOS) rate estimation problem in terminal guidance of air-to-air combat. The measurements of target azimuth and elevation are obtained by missile-borne active radar seeker which use a monopulse doppler radar. As it cant be directly measured by this kind of radar, the LOS rate which is needed as the input of guidance law should be estimated from these angle measurements. The close-loop simulation of LOS rate estimation in typical terminal guidance scenario that an air-to-air missile seeks a military fighter validates the presented algorithm.

An Improved Routing Algorithm Based on LEACH for WSN
Authors: Liu Yong Chao , Zhang Yue Xia , Miao Min
Published: October 2015

It is especially important to save energy and prolong the network lifetime because the WSN nodes energy is limited. Optimizing the routing algorithm for WSN is one of the important ways to reduce energy consumption. LEACH routing protocol is the first cluster-based routing protocol for wireless sensor networks. But LEACH have some deficiencies, such as agreement of uneven clustering, the nodes energy imbalance, frequent clustering and consume too much energy. The paper proposes an improved LEACH protocol to solve the above problem. It takes the residual energy of the nodes into account when nodes selected the cluster-head so that the nodes that hold high-energy have the high possibility to be selected as cluster-head. The improved algorithm uses the incomplete clustering which does not need to cluster every round but interval cluster. Simulation results show that the improved LEACH protocol effectively increases the nodes energy utilization and extends the network lifetime.

Dynamic detection method based on software behavior is an efficient and effective way for anti-virus technology. Malware and benign executable differ mainly in the implementation of some special behavior to propagation and destruction. A program's execution flow is essentially equivalent to the stream of API calls. Analyzing the API calls frequency from six kinds of behaviors in the same time has the very well differentiate between malicious and benign executables. This paper proposed a dynamic malware detection approach by mining the frequency of sensitive native API calls and described experiments conducted against recent Win32 malware. Experimental results indicate that the detection rate of proposed method is 98% and the value of the AUC is 0.981. Furthermore, proposed method can identify known and unknown malware.

Online group-buying (OGB) has attracted a lot of interest among academics and practitioners. Although there is an abundance of studies on OGB, most studies on OGB aims on how to enhance the consumers adoption, the studies related to the determinants of consumers continuance intention and discontinue using anomalies are still insufficient. To identify the determinants that influence consumers continuance intention in OGB and establish generalize ability is crucial due to an empirical study measuring continuance intention would enable OGB platforms providers and consumers to improve their adoption and continuance intention. Emerging design approach: User eXperience Design (UXD) could provide learner with great user experience to alleviate the above issues. This paper synthesizes the Information System Success Model (ISSM) and the ExpectationConfirmation Theory (ECT) to establish an extension model based-on user experience perspective to discovery what critical factors affected the users benefit and users intentions to continue using OGB. Initial results of this study have shown our questionnaire reached good convergent and discriminate validities. In next steps, the promising model will be empirically tested with wider areas.

Published: October 2015

An algorithm of wavelet digital watermarking was proposed to improve the security of the watermark. First, the logistic chaotic sequence was used to generate an encrypted image watermarking, then discrete wavelet transform (DWT) was used to decompose the original image and the watermark was embedded into the selected frequency band of significant wavelet coefficients. Finally, an approach for extraction was adopted. Experimental results show that the watermark is robust to attacks if the chaotic key is unknown.

Authors: Dong Jing , Xia Yang
Published: October 2015

In this paper, a real-time video stabilization algorithm based on smoothing feature trajectories is proposed. For each input frame, our approach generates multiple feature trajectories by performing inter-frame template match and optical flow. A Kalman filter is then performed to smooth these feature trajectories. Finally, at the stage of image composition, the motion consistency of the feature trajectory is considered for achieving a visually plausible stabilized video. The proposed method can offer real-time video stabilization and its removed the delays for caching coming images. Experiments show that our approach can offer real-time stabilizing for videos with various complicated scenes.
