Prediction Model of the Power System Frequency Using a Cross-Entropy Ensemble Algorithm
Authors: Tang Yi , Cui Han , Wang Qi
Published: October 2017

Frequency prediction after a disturbance has received increasing research attention given its substantial value in providing a decision-making foundation in power system emergency control. With the advancing development of machine learning, analysis power systems with machine-learning methods has become completely different from traditional approaches. In this paper, an ensemble algorithm using cross-entropy as a combination strategy is presented to address the trade-off between prediction accuracy and calculation speed. The prediction difficulty caused by inadequate numbers of severe disturbance samples is also overcome by the ensemble model. In the proposed ensemble algorithm, base learners are selected following the principle of diversity, which guarantees the ensemble algorithm’s accuracy. Cross-entropy is applied to evaluate the fitting performance of the base learners and to set the weight coefficient in the ensemble algorithm. Subsequently, an online prediction model based on the algorithm is established that integrates training, prediction and updating. In the Western System Coordinating Council 9-bus (WSCC 9) system and the Institute of Electrical and Electronics Engineers 39-bus (IEEE 39) system, the algorithm is shown to significantly improve the prediction accuracy in both sample-rich and sample-poor situations, verifying the effectiveness and superiority of the proposed ensemble algorithm.
G-Protein Dependent Signal Transduction and Ubiquitination in Dictyostelium
Authors: Pergolizzi Barbara , Bozzaro Salvatore , Bracco Enrico
Published: October 2017

Signal transduction through G-protein-coupled receptors (GPCRs) is central for the regulation of virtually all cellular functions, and it has been widely implicated in human diseases. These receptors activate a common molecular switch that is represented by the heterotrimeric G-protein generating a number of second messengers (cAMP, cGMP, DAG, IP3, Ca2+ etc.), leading to a plethora of diverse cellular responses. Spatiotemporal regulation of signals generated by a given GPCR is crucial for proper signalling and is accomplished by a series of biochemical modifications. Over the past few years, it has become evident that many signalling proteins also undergo ubiquitination, a posttranslational modification that typically leads to protein degradation, but also mediates processes such as protein-protein interaction and protein subcellular localization. The social amoeba Dictyostelium discoideum has proven to be an excellent model to investigate signal transduction triggered by GPCR activation, as cAMP signalling via GPCR is a major regulator of chemotaxis, cell differentiation, and multicellular morphogenesis. Ubiquitin ligases have been recently involved in these processes. In the present review, we will summarize the most significant pathways activated upon GPCRs stimulation and discuss the role played by ubiquitination in Dictyostelium cells.
New Methods of Esterification of Nanodiamonds in Fighting Breast Cancer—A Density Functional Theory Approach
Authors: Landeros-Martinez Linda-Lucila , Glossman-Mitnik Daniel , Orrantia-Borunda Erasmo , Flores-Holguín Norma
Published: October 2017

The use of nanodiamonds as anticancer drug delivery vehicles has received much attention in recent years. In this theoretical paper, we propose using different esterification methods for nanodiamonds. The monomers proposed are 2-hydroxypropanal, polyethylene glycol, and polyglicolic acid. Specifically, the hydrogen bonds, infrared (IR) spectra, molecular polar surface area, and reactivity parameters are analyzed. The monomers proposed for use in esterification follow Lipinski’s rule of five, meaning permeability is good, they have good permeation, and their bioactivity is high. The results show that the complex formed between tamoxifen and nanodiamond esterified with polyglicolic acid presents the greatest number of hydrogen bonds and a good amount of molecular polar surface area. Calculations concerning the esterified nanodiamond and reactivity parameters were performed using Density Functional Theory with the M06 functional and the basis set 6–31G (d); for the esterified nanodiamond–Tamoxifen complexes, the semi-empirical method PM6 was used. The solvent effect has been taken into account by using implicit modelling and the conductor-like polarizable continuum model.

Published: October 2017

Menthae Haplocalycis herba, one kind of Chinese edible herbs, has been widely utilized for the clinical use in China for thousands of years. Over the last decades, studies on chemical constituents of Menthae Haplocalycis herba have been widely performed. However, less attention has been paid to non-volatile components which are also responsible for its medical efficacy than the volatile constituents. Therefore, a rapid and sensitive method was developed for the comprehensive identification of the non-volatile constituents in Menthae Haplocalycis herba using ultra-high performance liquid chromatography coupled with linear ion trap-Orbitrap mass spectrometry (UHPLC-LTQ-Orbitrap). Separation was performed with Acquity UPLC® BEH C18 column (2.1 mm × 100 mm, 1.7 μm) with 0.2% formic acid aqueous solution and acetonitrile as the mobile phase under gradient conditions. Based on the accurate mass measurement (<5 ppm), MS/MS fragmentation patterns and different chromatographic behaviors, a total of 64 compounds were unambiguously or tentatively characterized, including 30 flavonoids, 20 phenolic acids, 12 terpenoids and two phenylpropanoids. Finally, target isolation of three compounds named Acacetin, Rosmarinic acid and Clemastanin A (first isolated from Menthae Haplocalycis herba) were performed based on the obtained results, which further confirmed the deduction of fragmentation patterns and identified the compounds profile in Menthae Haplocalycis herba. Our research firstly systematically elucidated the non-volatile components of Menthae Haplocalycis herba, which laid the foundation for further pharmacological and metabolic studies. Meanwhile, our established method was useful and efficient to screen and identify targeted constituents from traditional Chinese medicine extracts.
Glucopyranosylidene-Spiro-Thiazolinones: Synthetic Studies and Determination of Absolute Configuration by TDDFT-ECD Calculations
Authors: Szabó Katalin , Kun Sándor , Mándi Attila , Kurtán Tibor , Somsák László
Published: October 2017

Reactions of O-peracylated C-(1-bromo-β-d-glucopyranosyl)formamides with thioamides furnished the corresponding glucopyranosylidene-spiro-thiazolin-4-one. While O-debenzoylations under a variety of conditions resulted in decomposition, during O-deacetylations the addition of MeOH to the thiazolinone moiety was observed, and with EtOH and water similar adducts were isolated or detected. The structure and stereochemistry of the new compounds were established by means of NMR and electronic circular dichroism (ECD) data supported by time-dependent density functional theory ECD (TDDFT-ECD) calculations. TDDFT-ECD calculations could efficiently distinguish the proposed epimeric products having different absolute configuration in the spiro heterocyclic ring.
Rapid Screening of Active Components with an Osteoclastic Inhibitory Effect in Herba epimedii Using Quantitative Pattern–Activity Relationships Based on Joint-Action Models
Authors: Yuan Xiao-Yan , Wang Meng , Lei Sheng , Yang Qian-Xu , Liu Yan-Qiu
Published: October 2017

Screening of bioactive components is important for modernization and quality control of herbal medicines, while the traditional bioassay-guided phytochemical approach is time-consuming and laborious. The presented study proposes a strategy for rapid screening of active components from herbal medicines. As a case study, the quantitative pattern–activity relationship (QPAR) between compounds and the osteoclastic inhibitory effect of Herba epimedii, a widely used herbal medicine in China, were investigated based on joint models. For model construction, standard mixtures data showed that the joint-action models are better than the partial least-squares (PLS) model. Then, the Good2bad value, which could reflect components’ importance based on Monte Carlo sampling, was coupled with the joint-action models for screening of active components. A compound (baohuoside I) and a component composed of compounds with retention times in the 6.9–7.9 min range were selected by our method. Their inhibition rates were higher than icariin, the key bioactive compound in Herba epimedii, which could inhibit osteoclast differentiation and bone resorption in a previous study. Meanwhile, the half-maximal effective concentration, namely, EC50 value of the selected component was 7.54 μg/mL, much smaller than that of baohuoside I—77 μg/mL—which indicated that there is synergistic action between compounds in the selected component. The results clearly show our proposed method is simple and effective in screening the most-bioactive components and compounds, as well as drug-lead components, from herbal medicines.

Published: October 2017

The phenolic composition of aerial parts from Petiveria alliaceae L., Phyllanthus niruri L. and Senna reticulata Willd., species commonly used in Costa Rica as traditional medicines, was studied using UPLC-ESI-TQ-MS on enriched-phenolic extracts. Comparatively, higher values of total phenolic content (TPC), as measured by the Folin-Ciocalteau method, were observed for P. niruri extracts (328.8 gallic acid equivalents/g) than for S. reticulata (79.30 gallic acid equivalents/g) whereas P. alliaceae extract showed the lowest value (13.45 gallic acid equivalents/g). A total of 20 phenolic acids and proanthocyanidins were identified in the extracts, including hydroxybenzoic acids (benzoic, 4-hydroxybenzoic, gallic, prochatechuic, salicylic, syringic and vanillic acids); hydroxycinnamic acids (caffeic, ferulic, and p-coumaric acids); and flavan-3-ols monomers [(+)-catechin and (−)-epicatechin)]. Regarding proanthocyanidin oligomers, five procyanidin dimers (B1, B2, B3, B4, and B5) and one trimer (T2) are reported for the first time in P. niruri, as well as two propelargonidin dimers in S. reticulata. Additionally, P. niruri showed the highest antioxidant DPPH and ORAC values (IC50 of 6.4 μg/mL and 6.5 mmol TE/g respectively), followed by S. reticulata (IC50 of 72.9 μg/mL and 2.68 mmol TE/g respectively) and P. alliaceae extract (IC50 >1000 μg/mL and 1.32 mmol TE/g respectively). Finally, cytotoxicity and selectivity on gastric AGS and colon SW20 adenocarcinoma cell lines were evaluated and the best values were also found for P. niruri (SI = 2.8), followed by S. reticulata (SI = 2.5). Therefore, these results suggest that extracts containing higher proanthocyanidin content also show higher bioactivities. Significant positive correlation was found between TPC and ORAC (R2 = 0.996) as well as between phenolic content as measured by UPLC-DAD and ORAC (R2 = 0.990). These findings show evidence for the first time of the diversity of phenolic acids in P. alliaceae and S. reticulata, and the presence of proanthocyanidins as minor components in latter species. Of particular relevance is the occurrence of proanthocyanidin oligomers in phenolic extracts from P. niruri and their potential bioactivity.
A New Insight in Determining the Percolation Threshold of Electrical Conductivity for Extrinsically Conducting Polymer Composites through Different Sigmoidal Models

Published: October 2017

The electrical conductivity of extrinsically conducting polymer composite systems passes through a transition state known as percolation threshold. A discussion has been made on how different Sigmoidal models (S-models), such as Sigmoidal–Boltzmann (SB), Sigmoidal–Dose Response (SD), Sigmoidal–Hill (SH), Sigmoidal–Logistic (SL), and Sigmoidal–Logistic-1 (SL-1), can be applied to predict the percolation threshold of electrical conductivity for ethylene vinyl acetate copolymer (EVA) and acrylonitrile butadiene copolymer (NBR) conducting composite systems filled with different carbon fillers. An interesting finding that comes from these observations is that the percolation threshold for electrical conductivity determined by SB and SD models are similar, whereas, the other models give different result when estimated for a particular composite system. This similarity and discrepancy in the results of percolation threshold have been discussed by considering the strength, weakness, and limitation of the models. The percolation threshold value for the composites has also been determined using the classical percolation theory and compared with the sigmoidal models. Moreover, to check the universal applicability, these Sigmoidal models have also been tested on results from some published literature. Finally, it is revealed that, except SL-1 model, the remaining models can successfully be used to determine the percolation threshold of electrical conductivity for extrinsically conductive polymer composites.

Published: October 2017

Urban parks have been shown to form park cool islands (PCIs), which can effectively alleviate the negative influences of urban heat islands (UHI). However, few studies have examined the detailed characteristics of PCIs, the effect of urban park features on their individual temperatures, and monthly variation in PCIs. Land surface temperature (LST) retrieved from Landsat 8 TIR images between May and October were used to represent the thermal environment. Urban park characteristics were extracted from high-resolution GF-2 images. Using these datasets, the relationships between urban park characteristics and PCIs were explored in this study using Changchun, which has a snow climate, as a case study. The results showed the following: (1) the urban parks exhibited a cooling island effect, and the PCIs showed significant monthly variations with the highest intensities in the hot months; (2) the effects of composition (e.g., park size and the percentage of water area) on LSTs and PCIs showed significant monthly variability and were stronger than the configuration effects. Furthermore, an unexpected, negative correlation between PCIs and the area of park grass was also found; and (3) larger parks tended to have stronger PCI intensities and extents of influence. For parks larger than 30 ha, the cooling effects extended approximately 480 m from the park edge between June and August. For all of parks during the study duration, the rate of temperature increase was highest within 60 m from the park edge. The PCI we employ specifically in this study is characterized by LST.
Energy Performance Indicators in the Swedish Building Procurement Process
Authors: Allard Ingrid , Olofsson Thomas , Nair Gireesh
Published: October 2017

In Sweden, all new buildings need to comply with the National Board of Housing, Building and Planning’s requirement on specific purchased energy (kWh/m2). Accordingly, this indicator is often used to set design criteria in the building procurement process. However, when energy use is measured in finished buildings, the measurements often deviate significantly from the design calculations. The measured specific purchased energy does not necessarily reflect the responsibility of the building contractor, as it is influenced by the building operation, user behavior and climate. Therefore, Swedish building practitioners may prefer other indicators for setting design criteria in the building procurement process. The aim of this study was twofold: (i) to understand the Swedish building practitioners’ perspectives and opinions on seven building energy performance indicators (envelope air leakage, U-values for different building parts, average U-value, specific heat loss, heat loss coefficient, specific net energy, and specific purchased energy); and (ii) to understand the consequences for the energy performance of multi-family buildings of using the studied indicators to set criteria in the procurement process. The study involved a Delphi approach and simulations of a multi-family case study building. The studied indicators were discussed in terms of how they may meet the needs of the building practitioners when used to set building energy performance criteria in the procurement process.
Exploring the Organizational Culture’s Moderating Role of Effects of Corporate Social Responsibility (CSR) on Firm Performance: Focused on Corporate Contributions in Korea
Authors: Lee Myeongju , Kim Hyunok
Published: October 2017

The purpose of this study was to examine the role of organizational culture in helping to translate corporate social responsibility (CSR) into firm performance. We employed arguments from the CSR strategy view to highlight the effectiveness of CSR and the contingency approach to explain the vertical fit between CSR and the organizational culture in a firm. Furthermore, we examined the moderating influence of organizational culture on the CSR–firm performance linkage. The results suggest that some organizational cultures moderate the relationship between CSR and financial outcomes, and that organizational culture may play an important role in enhancing a positive relationship between CSR and firm performance.
Institutional Regime, Off-Farm Employment, and the Interaction Effect: What are the Determinants of Households’ Forestland Transfer in China?
Authors: Zhang Han , Kuuluvainen Jari , Ning Youliang , Liao Wenmei , Liu Can
Published: October 2017

The development of the land rental market has been widely attributed to the associated institutional regime and the functioning of the off-farm labor market. However, little is known of the interaction effect of these two factors. To fill this gap, we employ a nationwide representative household dataset to investigate the effects of China’s collective forest tenure reform (CFTR) and off-farm employment on forestland transfer in China. Special interest is focused on their potential interaction effect. The Smith-Blundell instrumental variable tobit model is adopted to account for the endogeneity of off-farm employment. The estimation results show that both the tenure reform and off-farm employment significantly influence forestland transactions. However, compared to the positive effect of the reform on both renting in and renting out forestland, the effect of off-farm employment is mixed, that is, its effect is negative when forestland is rented in but positive on rent-out decisions. An important finding is that the CFTR imposes a negative enhancement effect on forestland rent-in through its interaction term with off-farm employment. In contrast, the enhancement effect on rent-out is not statistically significant, which may be due to the neutralization by the endowment effect of the CFTR.
Adaptation Strategies for Water Resources: Criteria for Research
Authors: Salerno Franco
Published: October 2017

The Paris Agreement presents new fields of research related to the adaptation strategies to climate change. A challenge for future research consists in developing context-specific guidelines to support adaptation. This Special Issue on “Adaptation strategy to climate change for water resources” is born in this context. It contains 15 scientific studies facing a diversity of issues inherent to the adaptation strategies for water resources. This editorial analyses how the authors of this collection of papers decided to develop and present their research in order to identify criteria to contribute defining, in a near future, standardized approaches and practices for adaptation studies. Papers have been categorized in two major fields: “Studies for the development of adaptation scenarios” and “Studies for the development of adaptation solutions”. Papers belonging to both categories are generally found missing to treat the ‘uncertainty’ issues arising and the implementation of the proposed adaptation strategies. Studies investigating future adaptation scenarios are generally found to be unbalanced in favor of the assessment of future impacts on water resources and less towards the provision of adaptation scenarios. When these studies do not provide elements to manage the specific uncertainty related to the proposed adaptation solutions, at least exploring the uncertainty related to the climatic and impact scenarios is strongly recommended. Studies providing methodological and/or procedural examinations on adaptation solutions are recommended to suitably report the climatic, environmental, and social context for which the action has been developed. A reduction of uncertainty and an easier implementation of proposed measures could be induced from this.
Microsatellites for Phytolacca acinosa (Phytolaccaceae), a traditional medicinal herb1
Authors: Cheng Yueqin , Li Pingping , Yang Yi , Zhang Jianhang , Yan Fengming , Wang Hongwei
Published: October 2017

Premise of the study:

Phytolacca acinosa (Phytolaccaceae) is a traditional Chinese herb with multiple medicinal uses and is an important pigment source. Due to excessive human harvesting, the population numbers and sizes have decreased dramatically.

Methods and Results:

Using an enriched genomic library, we developed and characterized 15 microsatellite primers for P. acinosa, 13 of which were polymorphic. The number of alleles varied from two to seven. The observed heterozygosity and expected heterozygosity per locus ranged from 0.267 to 1.000 and 0.331 to 0.743, respectively. All of the primers that were developed were also successfully applied in P. americana.

Conclusions:

These markers should be useful in probing the genetic diversity, genetic structure, and mating systems of P. acinosa, which could provide information about protecting and sustainably harvesting this species.
Isolation and characterization of microsatellite markers for Hypochaeris incana (Asteraceae) and close relatives1
Authors: Wang Ping , Tremetsberger Karin , Urtubey Estrella , Bernhardt Karl‐Georg
Published: October 2017

Premise of the study:

We developed microsatellite markers to study clonal growth and interspecific hybridization in the Patagonian and subantarctic plant Hypochaeris incana (Asteraceae) and its closest relatives.

Methods and Results:

We developed primers for microsatellite loci from 454 sequence reads of genomic DNA of H. incana. We tested them on individuals of H. acaulis, H. hookeri, H. incana, H. palustris, and H. tenuifolia. We selected 15 polymorphic microsatellite loci, which delivered clearly scorable fragments in most or all species. With mean values between 0.7 and 0.8, the expected heterozygosity in populations of H. incana is high.

Conclusions:

Due to high levels of polymorphism, the developed markers make it possible to distinguish between genets and ramets in H. incana. In some markers, null alleles complicate the scoring of genotypes in tetraploids. All of the developed markers are suitable to study interspecific hybridization among this group of closely related species.
Impact of prenatal antimicrobial treatment on fetal brain damage due to autogenous fecal peritonitis in Wistar rats: A Histomorphometric Study
Authors: Gadelha Neylane , Gadelha Diego , Paz Alexandre , Melo Maria Cecilia , Oliveira Tharcia Kiara , Brandt Carlos
Published: October 2017

Purpose: To investigate brain neuronal density in newborn rats whose mothers were subjected to fecal peritonitis and compare findings between rats born to mothers treated and not treated with antimicrobials.

Methods: Peritonitis was induced with a 10% fecal suspension (4mL/kg) in 2 pregnant rats. Of these, 1 received antimicrobial treatment 24 hours after peritonitis induction: moxifloxacin and dexamethasone plus 2 mL of the inner bark of the Schinus terebinthifolius raddi extract. One pregnant rat underwent no intervention and served as a control.

Results: The newborn brains of rats born to mothers with fecal peritonitis were significantly smaller and of less firm consistency. Brain neuronal density was lower in the untreated group than in the control and treated groups (P<0.01).

Conclusions: Untreated peritonitis caused brain damage in the offspring, which was averted by effective early antimicrobial treatment. This approach may provide an early avenue for translation of such therapy in humans.

La psychiatrie, d’une migration à l’autre
Authors: Chebili Saïd
Published: October 2017

Antoine Porot et Frantz Fanon sont deux figures de la migration. L’un et l’autre sont allés exercer en tant que psychiatres en Algérie. Porot, malgré une œuvre clinique riche et originale, est resté prisonnier des théories constitutionnalistes à l’origine d’annotations racistes dans son travail théorique. Il a fondé l’école d’Alger qui a propagé ses idées à travers le célèbre Manuel de psychiatrie. Fanon, à l’inverse, grâce à une formation auprès des maîtres de la psychothérapie institutionnelle et à sa vaste culture philosophique, a pu se départir de l’idéologie dominante et élaborer une approche novatrice qui lui a permis de prendre en compte le contexte culturel dans lequel il exerçait son métier de psychiatre. Il n’a pas hésité à démissionner de ses fonctions lorsque les événements heurtaient sa conscience. Il a alors continué son parcours migratoire, jusqu’à son décès prématuré.
Pour en finir avec la castration
Authors: Martens Francis
Published: October 2017

Dans le sillage de la théorie de l’inconscient comme résidu refoulé de l’échec partiel de la traduction-appropriation des stimulations sensorielles (Freud, Lettre 52, 1896), Jean Laplanche a appelé mytho-symbolique l’encadrement culturel facilitant la régulation du sexuel au sens freudien. La traduction imposée à l’enfant des « messages énigmatiques » des adultes, pour leur donner sens et échapper à la confusion, ne part donc pas de rien. Dans le prolongement, j’ai proposé d’appeler aide à la traduction le codage variable mais non moins normatif de sept différences anthropologiques fondamentales (homme femme, par exemple) venant ordonner un foisonnement pulsionnel aussi nécessaire à la vie que peu compatible avec l’existence collective. Cette conception permet de distinguer deux niveaux complémentaires mais bien distincts au sein de la métapsychologie : le niveau universel du modèle scientifique anthropologique de l’inconscient individuel sexuel refoulé, et celui du codage relatif dans l’espace et le temps des sept différences constitutives du maillage mytho-symbolique des sociétés humaines. La non-distinction de ces deux niveaux – aggravée de leur confusion avec la théorie de la pratique clinique – rend impossible toute confrontation féconde de la théorie psychanalytique avec d’autres modèles scientifiques. Il est à noter que la majorité des textes psychanalytiques (Lacan, notamment) et la plupart des textes de Freud se situent au second niveau (Œdipe, nom-du-père, castration). Héritant tout en s’en différenciant de l’environnement mytho-symbolique où elle a vu le jour, la psychanalyse reste imprégnée de discours idéologiques s’appuyant sur une prétendue « nature des choses » pour préserver des intérêts particuliers. Issue plus particulièrement de l’auto-analyse très partielle de son fondateur, la théorie psychanalytique écope d’une partie des préjugés et des constructions autodéfensives de Freud. Elle peine encore à s’en affranchir. Parmi ces idées reçues, le thème emblématique de la castration n’est qu’une variante mytho-symbolique typique – et métapsychologiquement inutile – des clichés masculins les plus basiques à l’égard des femmes et du féminin.
« Je ne cherche pas je trouve » en forme d’aliénation
Authors: Charreau Marguerite
Published: October 2017

Les références à la formule de Picasso « je ne cherche pas je trouve » ont entraîné chez Lacan des positionnements contraires au cours de son enseignement, soit qu’il la prenne à son compte, soit qu’il en inverse le propos. S’agit-il alors pour la psychanalyse d’être du côté de la recherche, ou bien du côté de la trouvaille ? L’opération logique de l’aliénation, par le recours à la fabrication de formes grammaticales, se présente comme ce qui permet de dépasser cette apparente contradiction.
L’éclair-obscur

Published: October 2017

L’idée de la passe comme « éclair » s’est répandue comme une traînée de poudre dans la mouvance lacanienne. Mais sait-on ce que l’on dit lorsqu’on use de cette formule et comment s’est fabriquée une telle assertion ? S’agirait-il d’une allusion métaphorique ou d’un phénomène physique qui caractériserait cette modulation de la vérité ? La lecture du séminaire que Fink et Heidegger consacrèrent aux Fragments d’Héraclite pourrait éclairer cette question.
Louise Michel, féministe : analyse d’une opération de qualification politique aux débuts de la III e République
Authors: Verhaeghe Sidonie
Published: October 2017

Cet article montre comment la presse a contribué à construire Louise Michel comme une figure féministe au début de la III e République, alors même qu’elle refuse de se définir comme telle. Résultant de l’implication conjointe d’acteurs politiquement opposés, cette mise en visibilité féministe de Louise Michel révèle que la célébrité est un mode d’expression du politique qui construit une personnalité à travers un système de valeurs et d’idées dont elle devient l’incarnation glorieuse ou repoussoir. Se joue donc ici une opération de qualification politique de la figure de Louise Michel, qui dévoile les rivalités dans la façon de définir et de percevoir la question du féminisme.

À partir d’une étude comparée de Elle et Marie Claire , l’article interroge l’existence d’une parenthèse féministe dans certains titres de presse féminine des années 1968. Le contexte social, politique et commercial permet à ces journaux de défendre les droits des femmes. S’intéressant à deux formats particuliers : l’Encyclopédie de Elle (1968-1970) et les pages femmes de Marie Claire (1976-1990), l’article dévoile les conditions matérielles de cette conversion politique qui se traduit par une « mise à l’encart » du féminisme.
Lutter contre le sexisme dans les médias : des usages stratégiques du droit par les associations féministes françaises
Authors: Granchet Agnès
Published: October 2017

Les associations féministes françaises font un usage contrasté des procédures offertes par le droit et la déontologie contre les messages sexistes diffusés par les médias. Faiblement mobilisées devant les juridictions et l’instance de régulation de l’audiovisuel, elles sont plus actives devant le Jury de déontologie publicitaire. En sensibilisant au sexisme, cette utilisation sélective et ciblée des procédures existantes participe à la légitimation des revendications féministes.
The Beyoncé Wars : le Black feminism , Beyoncé et le féminisme hip-hop
Authors: Djavadzadeh Keivan
Published: October 2017

Cet article entend rendre compte des controverses liées au positionnement féministe de Beyoncé depuis 2013. Il s’agira d’abord de retracer l’évolution féministe de Beyoncé, depuis son album éponyme en 2013, dans lequel elle se déclare féministe pour la première fois, jusqu’au plus récent Lemonade (2016). Cela afin de montrer que la politisation récente du féminisme chez la chanteuse, qui apparaît moins « pop » et moins « fun » que par le passé, coïncide avec l’intégration d’un discours antiraciste dans le sillage du mouvement Black Lives Matter . Aussi, il sera question de la réception du discours de la chanteuse, tant dans les médias qu’au sein du féminisme africain-américain, les premiers s’étant notamment fait l’écho des débats internes au Black feminism afin de mettre en doute la légitimité de Beyoncé à se réclamer du féminisme.
Preparation of β-belite using liquid alkali silicates
Authors: Koutník P.
Published: October 2017

The aim of this study is the preparation of β-belite by a solid-state reaction using powdered limestone, amorphous silica and liquid alkali silicates. The raw materials were blended, the mixtures were agglomerated and then burnt. The resulting samples were characterized by X-ray diffraction analysis and scanning electron microscopy. Free lime content in the β-belite samples was also determined. The effects of CaO/SiO2 ratio (1.6–2.1), burning temperature (800–1400 °C), utilization of different raw materials (silica fume, synthetic silica, potassium silicate, sodium silicate, potassium hydroxide) and burning time (0.5–16 h) on free lime content and mineralogical composition were investigated. The purest ?-belite samples were prepared from a mixture of powdered limestone, silica fume and liquid potassium silicate with a ratio CaO/SiO2 = 2 by burning at temperatures between 1100 and 1300 °C for more than 2 h. Decreasing of the CaO/SiO2 ratio led to rankinite formation and lower a burning temperature led to the formation of wollastonite.
Online Service Failure and Recovery Strategies in Luxury Brands
Authors: Ozuem Wilson , Azemi Yllka
Published: October 2017

Digital environment no longer permits marketers' self-isolated practices into offline business contours. A tighter relationship of the provider-customer is even more evident in luxury brands, where rather than the quality of the product, the perceived experience (i.e., emotion) drives the purchasing decision and plays the mediating role to customer satisfaction. The risk that online environment does not permit development of such experience subsequently that failure awakening would increase and recovery would be an unmanageable issue, seems to keep luxury brands skeptical of online environment. While other industries are already taking inclusive advantage of multidimensional features inherited in the online medium, luxury brands are situated in the very initial stage of familiarizing with digital media. Subsequently, the phenomena lack theoretical explanation, particularly in context to failure and recovery. The current chapter discusses service failure and recovery strategy in luxury brands, aiming to bring conceptual insight to it.

Drivers, Constraints, and Consequences of Consumer-Brand Engagement in the Luxury Fashion Sector
Authors: Armstrong Kate , Rutter Charlotte , Helberger Eva , Tormey Ambre
Published: October 2017

The purpose of this chapter is to conceptually explore the drivers and constraints of the Consumer Brand Engagement (CBE) concept in the context of the luxury fashion retail sector, along with identifying the resulting consumer behavioural outcomes for this specific industry genre. Using the theoretical lens of the CBE Scale, a consumer viewpoint is taken in order to gauge an in-depth understanding of engagement during or related to focal brand interactions, through the dimensions of Cognitive Processing, Affection and Activation. The CBE concept is gaining traction in branding academia due to its predictive qualities in determining consumer behavioural outcomes, such as loyalty, and so is considered insightful for luxury fashion management. Little research has been conducted in this discipline utilising the lens of CBE as a conceptual framework.
Knowledge Crises in Ethiopia
Authors: Wudie Alelign Aschale
Published: October 2017

Ethiopian knowledge and intellectualism has been squinted for the millennia. Using a trans-disciplinary design, knowledge and intellectual crises in Ethiopia was analysed philosophically by tracing the networks of knowledge and mind. From the endeavor, it is found out that transdisciplinary orders and practices compelled Ethiopia to lose her true genealogy of epistemology. The theo-culture and social structure, events and practices accentuated the threaded sagas of knowledge. Empires and big Dynasties were redacted to small states and kingdoms. Through redaction of authentic knowledge and belief system, Ethiopian system was lost; universal knowledge has become very local and the antithesis is true. In Ethiopia, the forces of taboos were mightier than the forces of man and education. Besides, Ethiopian knowledge suffered from several socio-economic, psychological and historical phenomena. Together, people can do anything they can. Every Ethiopian shall explore true Ethiopianism in history and strive for deconstructing crises and reconstructing the ancient wonderful Ethiopia.

Published: October 2017

Scientific and technological advances and economic globalization impose new requirements on the organization of domestic economy. Knowledge economy development principles were formulated in order to understand current processes. Special attention was paid to specific features of the knowledge economy. A comprehensive approach proposed by the World Bank was studied under a special Knowledge for Development Program (K4D) to assess country's economic readiness to shift to the knowledge economy model. Countries were ranged based on the Knowledge Economy Index and top-10 countries were selected. Such indices as the Global Innovation Index, the Human Development Index and collections of analytic works also indicate a transfer to the knowledge economy. The development of the Global Innovation Index was studied and top-10 countries having the highest indices were selected. A research was made into the Human Development Index and its dynamics in Russia and in G20 countries was analyzed over the period of 1995 – 2015.

Organisational Learning Dimensions and Talent Retention Strategies for the Service Industries
Authors: Atiku Sulaiman Olusegun , Fields Ziska
Published: October 2017

This chapter explores the contributions of organisational learning dimensions and talent retention strategies within an organisation to the development of innovative products/services and business sustainability. A literature review approach was adopted to investigate the link between intra/inter-organisational learning, talent retention strategies and business sustainability. It was found that an organisation needs to invest in continual learning and retention of talented employees to ensure business sustainability in the service industries. The ability to keep high-calibre human capital within an organisation is one of the greatest sources of sustainable competitive advantage. Judging from the global demands for a high calibre of talents, it is extremely difficult if not impossible to retain talents within an organisation for a long period of time. This chapter proposes a framework for developing innovative products/services to enhance business sustainability in the service industry through continuous learning dimensions and upgraded talent retention strategies.

The accumulation of information formed by the scientific studies whose foundation stones were put during the Enlightenment period, caused the Industrial Revolution. The most important feature of the modern era was to have a deterministic science approach. The period we are in is called the Postmodern Era. General and Special Relativity Theories, new findings in Quantum Physics and the advances in communication technology caused deep and rooted social, cultural, political and economic change and transformation, and ultimately led to a significant paradigm change. The most important feature of this period is that it has a Relative science approach. While change and transformation are continuing, it is not enough to simply feel and be aware of the rapid change and transformation of culture, education and training. In this study, changes and transformations during the Renaissance up to the present has been tried to be indicated by the results of scientific studies.
Evaluating Trends and Issues in Distance Learning
Authors: Khadimally Seda
Published: October 2017

Today's learners are intrinsically motivated in that they are apt to analyze, synthesize, internalize, rebuild, share, and disseminate knowledge not only with their instructors, but also their peers, and the greater community, including a plethora of learning communities from across the world. Web-based technologies play a key role in this learning process. Particularly online social media networks and mobile technologies, the two selected technology trends evaluated in this paper, are thriving in online learning/teaching settings, immensely helping students acquire valid learning gains. These technologies are not a fad, a myth, or talk-of-the-day in learning and teaching environments in any given discipline. With that said, there are also certain issues and challenges that accompany these media and technologies for learning and teaching practices, which will also be addressed in this paper. Finally, future implications on these trends and issues in DL will be further discussed with the hope that educational leaders can draw on them for further inquiry and development in the field.
Culture in Online Learning
Authors: Saykili Abdullah
Published: October 2017

Culture and learning form a tapestry of indistinguishably interwoven elements that continuously interact and shape each other. Connective technologies potentially increase intercultural interaction among the members of learning communities that can embrace greater numbers of individuals from diverse cultural orientations. The unpredictable and varying natures of culture and online learning lead researchers to continually revisit and explore key properties, processes, and issues in culture and online learning. Therefore, this article firstly gives an account of how culture is contested and highlights the challenge of providing an all-comprehensive definition. Further, it focuses on the role of culture in online learning and briefly presents both the essentialist and post-essentialist frameworks of culture utilized to provide insights into the role of culture in online learning. Finally, this chapter provides recommendations for a culturally-inclusive online learning and points towards future research directions.

Published: October 2017

In this study, the effect of educational computer games on students' academic success and their attitudes towards mathematics were investigated. The study was designed as a mixed method. The results revealed that after the implementation, no significant variation was observed between both groups in terms of academic test scores and attitude points. However, qualitative findings indicated that students in the experimental group got more pleasure from the lessons and their attitudes towards mathematics were positively affected. Also, educational computer games are effective learning tools and create a positive affirmation on students. Although this study was conducted in the face to face classrooms, the findings would be transferred to other learning settings such as distance and online education. Therefore, the experience obtained from such technologically enriched learning environments is discussed in the context of distance and online learning.
