Radioscopie de l'information télévisée au Canada
Authors: Monière Denis , Fortier Julie
Published: July 2018

Les différents diffuseurs offrent à leurs auditoires respectifs ni tout à fait la même information, ni le même traitement de l'actualité. En tenant compte de variables qu'on peut mesurer, comme le temps de parole accordé aux acteurs politiques ou le temps consacré par chaque chaîne aux nouvelles communes, Denis Monière et Julie Fortier montrent, chiffres à l'appui, que le journalisme canadien obéit, comme on s'y attendait, à des règles différentes selon le public auquel il s'adresse. Ils montrent aussi cependant que l'information est moins tributaire qu'on pourrait le croire des mandats officiels : ce n'est pas tant le statut public ou privé d'une chaîne qui importe en ce cas, que sa langue de diffusion.

Authors: Medeiros Tássia Karina Alexandre de , Silva Adnilson de Almeida , Suruí Gasodá Wawaeitxapôh , Filho Isaac Costa Araújo , Floriani Nicolas
Published: July 2018

O estudo busca retratar os etconhecimentos dos Paiterey sobre plantas, em conformidade com suas vivências e experiências ancestralmente adquiridas, que exercem poder de cura. Essas plantas são fundamentais na promoção da saúde em muitas regiões do Brasil, em particular para os povos originários que detêm um conhecimento etnobotânico e as utilizam no tratamento das enfermidades. O uso popular dessas plantas é uma prática antiga com acúmulo de informações que são reaplicadas entre sucessivas gerações. Em decorrência do convívio dos indígenas com a cultura da sociedade envolvente, o patrimônio cognitivo tradicional viu-se hibridizada com outras práticas de saúde moderna que muitas vezes subjugam a vasta experiência trazida pelos indígenas. Este estudo se propõe a analisar especificamente o caso da Aldeia Paiter - Linha 09, Terra Indígena Sete de Setembro, localizada a aproximadamente 50 quilômetros de Cacoal, Estado de Rondônia. Para tanto, o percurso metodológico adotado quanto ao recorte temporal e espacial e à abordagem dos sujeitos da pesquisa, com enfoque qualitativo de estudo de caso, em que procura destacar e interpretar a experiência vivida pelos Paiterey e pelos investigadores acerca da diversidade biológica e paisagísticas constituintes das práticas do etnoconhecimento. A partir de elementos visuais e narrativos (relatos, entrevistas e reuniões com os Paiterey), os quais emergem elementos mítico-espirituais e práticos da etnomedicina, associados à diversidade biológica do território, a qual se relaciona à própria defesa territorial. Assim, a busca consiste em apreender a finalidade de plantas com poder originárias da floresta, bem como sua ressignificação como elemento importante nas estratégias de cooperação entre os atores sociais, tais como a academia, ao tempo em que esse povo procura a visibilidade da cultura e reconhecimento de seus direitos socioterritoriais, associadas à formação e capacitação dos futuros líderes indígenas – ainda que a pressão externa exercida sobre seu território implica em perdas da biodiversidade.
Territórios em disputas na Amazônia brasileira: ribeirinhos e camponeses frente as hidrelétricas e ao agronegócio
Authors: Silva Ricardo Gilson da Costa , Lima Luís Augusto Pereira , Conceição Francilene Sales da
Published: July 2018

A Amazônia brasileira se converteu em espaço apropriado por grandes obras hidrelétricas e de expansão do agronegócio sojeiro, mobilizando empresas nacionais e internacionais em busca de novas áreas para transformar a natureza em mercadoria. Tal geografia se torna mais complexa na medida em que o território disputado atinge comunidades tradicionais amazônicas, que sofrem as pressões sociais e territoriais desse processo modelizador da região. Assim, analisam-se tais processos nas comunidades ribeirinhas atingidas pelas hidrelétricas do Madeira, em Porto Velho (Rondônia), e comunidades camponesas de Belterra e Santarém (Pará). Conclui-se que esses grupos sociais têm seus territórios transformados pela expansão do capital na Amazônia, em regiões que ainda não fora objeto de transformação da natureza em mercadorias. Significa que as comunidades tradicionais amazônicas, mesmo habitando as áreas mais remotas na Amazônia, estão ameaçadas em sua condição socioterritorial.
Qualificar a cidade para o pedestre - um tema histórico e um desafio atual para o município (São Paulo)
Authors: Canova Katia
Published: July 2018

Os estudos urbanos sempre estiveram mais pautados pelos modos econômicos e suas técnicas de produção que às formas de apropriação pelos cidadãos que nela vivem ou usufruem. Somente na década de 1960 começam a surgir autores como Henri Lefebvre, Milton Santos e Jane Jacobs, que propõem uma nova discussão para o espaço urbano: a importância do olhar e a percepção do usuário, a escala humana, os espaços públicos, a riqueza da diversidade, o valor da conectividade/acessibilidade e a necessidade vital da prática de reuso e preservação do patrimônio construído e memória dos lugares. Além desses surgem Mark Girouard e Fraya Frehse com uma investigação mais histórica e social das dinâmicas urbanas, Jan Gehl e Janette Sadik-Kahn com aplicações práticas e de rápidas transformações de espaços públicos, transformando áreas subutilizadas pela prática rodoviarista dos anos de 1950 em lugares de estar, de contemplação, enfim de usufruto das pessoas que vivenciam a experiência de pedestre e ciclista em grandes cidades mundiais. Este trabalho traz também a discussão de indicadores numéricos e cartográficos para suporte de decisões de planejamento urbano, assim como a diversificação de grupos de discussão e aplicação de novas soluções para a apropriação dos lugares públicos urbanos.
A Survey of Parallel Indexing Techniques for Large-Scale Moving Object Databases
Authors: Leal Eleazar , Gruenwald Le , Zhang Jianting
Published: July 2018

A moving object database is a database that tracks the movements of objects. As such, these databases have business intelligence applications in areas like trajectory-based advertising, disease control and prediction, hurricane path prediction, and drunk-driver detection. However, in order to extract knowledge from these objects, it is necessary to efficiently query these databases. To this end, databases incorporate special data structures called indexes. Multiple indexing techniques for moving object databases have been proposed. Nonetheless, indexing large sets of objects poses significant computational challenges. To cope with these challenges, some moving object indexes are designed to work with parallel architectures, such as multicore CPUs and GPUs (graphics processing units), which can execute multiple instructions simultaneously. This chapter discusses business intelligence applications of parallel moving object indexes, identifies issues and features of these techniques, surveys existing parallel indexes, and concludes with possible future research directions.
Large Multivariate Time Series Forecasting
Authors: Hmamouche Youssef , Przymus Piotr Marian , Alouaoui Hana , Casali Alain , Lakhal Lotfi
Published: July 2018

Research on the analysis of time series has gained momentum in recent years, as knowledge derived from time series analysis can improve the decision-making process for industrial and scientific fields. Furthermore, time series analysis is often an essential part of business intelligence systems. With the growing interest in this topic, a novel set of challenges emerges. Utilizing forecasting models that can handle a large number of predictors is a popular approach that can improve results compared to univariate models. However, issues arise for high dimensional data. Not all variables will have direct impact on the target variable and adding unrelated variables may make the forecasts less accurate. Thus, the authors explore methods that can effectively deal with time series with many predictors. The authors discuss state-of-the-art methods for optimizing the selection, dimension reduction, and shrinkage of predictors. While similar research exists, it exclusively targets small and medium datasets, and thus, the research aims to fill the knowledge gap in the context of big data applications.

Assessment of Learning in Higher Education
Authors: Fallahi Mitra
Published: July 2018

This chapter discusses that the goal of assessment, as a part of teaching, in higher education should be to prepare the learner for performing in real life as a professional. The learner should become a self-regulator and a self-evaluator. The instructor (faculty, supervisor, or mentor) at the university must understand that assessment is a process of coaching and assisting, not just approving students' achievement. Technology acquired by the universities in the form of learning management systems (LMS) can be used to provide feedback and assistance to a large number of students. The role of feedback is discussed as an essential component of assessment that would help students to reflect and learn. Rubrics must be used as a tool to provide feedback to students instead of just grading assignments.
Film and Superheroes as a Pedagogic Tool
Authors: Bendall Mark J.
Published: July 2018

Hollywood film has a mass-market and global appeal. As such it is already well received and known by many learners and offers a method to build from this into more sophisticated theoretical concepts. The chapter makes the case for film as a viable and valuable teaching strategy. In an environment where many are visual learners, film offers a multisensory pedagogic tool which can draw students away from the handheld mobile devices which often compete for attention with the lecturer. It also notes the risks in film and answers potential objections. Then it applies these broader pedagogic concerns to the specific case of superhero films, and how it can illuminate complex terminology in social sciences, such as polysemy, inter-textuality, sociopolitics, psychopolitics, cultural and visual criminology. Other concepts discussed include notions of the denotative and the connotative, and the metonym. Questions of identity, gender, nation, and liminality are included.
Roald Dahl's Charlie and the Chocolate Factory as a School Reading
Authors: Michułka Dorota Mariola
Published: July 2018

This chapter aims to develop a new analysis formula and a new language of literary school education/teaching literature, especially the language of reading engagement functionalized in terms of emotional, social, and cultural needs that literature is capable of satisfying. This applies also to young readers. The starting point is the specificity of emotional and sensory reception of literary narration (e.g. Charlie and the Chocolate Factory by R. Dahl) in which vivid, multisensory mental imagery absorbs/engages many readers (also on the principle of intersubjective cooperation). Discussion in this chapter is based on three issues: transactional theory of reading response (with aesthetic and efferent reading); individual, personal, and private interpretations; and analysis of types of affect in reception. It also proposes a description of the process of pupils' cognitive activities, recognize mental images, understanding metaphors, and express emotions.
Creating Multimodal Texts for Language Learning Purposes
Authors: Gajek Elżbieta
Published: July 2018

The idea of creating short educational video clips oriented on the language, culture, or communication is well grounded in language learning pedagogy. They support comprehension and language skills of the students, intercultural competence, and digital skill. They change repetitive tasks such as rehearsal or rote learning into attractive and motivating activities well embedded in situated learning procedures making learning more personal. The study aims at analysis of the content of over 280 video clips made by pre-service language teachers between 2008-2014. The clips are intended for a variety of educational purposes (e.g., introducing new language, illustrating usage, enhancing practice, documenting performance, and assessment). Students used subtitles, intertitles, and narrative revoicing a story. They produced various genres. The results show that student teachers are able to produce multimodal texts to enhance various stages of learning and teaching processes (presentation, practice, and assessment) while developing six out of eight lifelong learning competences.
Perceived Destination Image
Authors: Cavlak Neslihan , Cop Ruziye
Published: July 2018

The perceived destination image is a strategic weapon that provides a competitive advantage for the tourism destinations. Perceptions are the elements that give meaning to destinations. In this respect, it is important for the destination marketers to know how tourists perceive the destination. It can be seen that tourists with different demographic and cultural backgrounds who visit the same destination can perceive its image differently. The tourism marketplace is highly competitive. Because of this, destination management organizations (DMOs) need to understand the actual and the desired perception of their destinations in order to take necessary measures. In this chapter, the concepts of destination and perceived destination image are emphasized. Secondly, the political environment, cultural attractiveness, social environment, and natural environment factors affecting the perceived destination image will be examined. Finally, the perceived destination images of domestic and foreign tourists visiting the Gallipoli in Turkey will be examined comparatively.
Technology and the Preparation of Students
Authors: Cardullo Victoria M. , Zygouris-Coe Vassiliki (“Vicky”) I. , Wilson Nance S.
Published: July 2018

The evolution of technology has situated learning to create a ubiquitous environment. The progression of technology will require preparation of students and teachers for the 21st century, including post-secondary students, necessitating a fundamental and systematic change for learning to become ubiquitous. Ubiquitous environments should be viewed through the lens of the learner and the learning environment. Equal access for all students should be prevalent so students can have access to mobile learning devices anytime, anywhere, thus, transcending the boundaries of the classroom. Integration of m-learning and ubiquitous technology in the K-20 classroom will require a new pedagogical framework for teaching and learning. At the heart of this framework, is the metacognitive teacher: a teacher who is metacognitively aware of the affordances and challenges of technology in education.
Active Learning and Self-Determination for the Management of Differences in the Classroom
Authors: Patrizia Oliva , Murdaca Anna Maria , Penna Assunta
Published: July 2018

The contexts of active learning, be they cooperative or flipped, are considered environments in which effective forms of learning are developed and students report greater satisfaction of basic psychological needs, intrinsic motivation, and interest in the subjects studied compared to the peers included in classes with traditional teaching methods. The aim of this study is to investigate whether there are differences between students with disabilities and without any pathology, included in active learning contexts, in the level of satisfaction of basic psychological needs, in the perception of skills, in the perception of the classroom climate and in the motivation to learn. 100 students (age: M = 16.99; DS = 1.808), 33 with disabilities and 67 students with typical development were involved. The results confirmed, in addition to the impact of individual factors in the motivation to study (psychological needs and perception of skills), a significant relationship also emerged with the classroom climate, with the teaching strategies of active learning and functional and self-determined levels of motivation to study.
Mobile Apps Acceptability
Authors: Shehzaib Usman , Ferzund Javed , Asif Muhammad
Published: July 2018

This article describes how the mobile app market is growing day by day. Mobile app stores have created the opportunity for the users to publicly provide feedback on mobile apps that they have installed or used. In this way, users are involved in the design and development of mobile apps, which was done by designers and developers before. Online user reviews are a useful source to know the user's perception about mobile apps and thus provide a way of co-value creation. This article is conducted to investigate the factors affecting the acceptability of mobile Apps. Main purpose of this article is to use online reviews for construction of a model instead of using existing acceptance theories. The model proposed in this research is based on the analysis of reviews and app information extracted from the Google Play Store. The ratings and number of installs are two key indicators of the popularity of an app. Other characteristics like price, category and size also influence the user's selection of an app. The findings showed the appropriateness of the proposed model and hypotheses for evaluating mobile apps acceptability and popularity. This article provides mobile app developers and marketers with an insight into the mobile app popularity and acceptability dynamics.
Algorithm for Secure Hybrid Cloud Design Against DDoS Attacks
Authors: Bhardwaj Akashdeep , Goundar Sam
Published: July 2018

This article describes how cloud computing has become a significant IT infrastructure in business, government, education, research, and service industry domains. Security of cloud-based applications, especially for those applications with constant inbound and outbound user traffic is important. It becomes of the utmost importance to secure the data flowing between the cloud application and user systems against cyber criminals who launch Denial of Service (DoS) attacks. Existing research related to cloud security focuses on securing the flow of information on servers or between networks but there is a lack of research to mitigate Distributed Denial of Service attacks on cloud environments as presented by Buyya et al. and Fachkha, et al. In this article, the authors propose an algorithm and a Hybrid Cloud-based Secure Architecture to mitigate DDoS attacks. By proposing a three-tier cloud infrastructure with a two-tier defense system for separate Network and Application layers, the authors show that DDoS attacks can be detected and blocked before reaching the infrastructure hosting the Cloud applications.
A Study on the Parameters in Hard Turning of High Speed Steel
Authors: Vijayan Krishnaraj , Gouthaman N. , Rathinam Tamilselvan
Published: July 2018

The objectives of hard turning of high speed steel (HSS-M2 Grade) are to investigate the effect of cutting parameters on cutting force, tool wear and surface integrity. This article presents the experimental results of heat treated high speed steel machined in a CNC lathe using cubic boron nitride (CBN) tools. Turing experiments were carried out using central composite design (CCD) method. From the experiments the influence of cutting parameters and their interactions on cutting forces, temperature and surface roughness (Ra) were analyzed. Following this, multi response optimization was done to find the best combination of parameters for minimum force, minimum temperature and minimum surface roughness. The experimental results showed that the most contributing factors were feed followed by depth of cut and spindle speed. A white layer formed during hard turning was also analyzed by scanning electron microscope (SEM) and the results showed that it was greatly influenced by the speed and depth of cut. Tool wear was experiments were conducted at the optimum cutting conditions and it was noted that the tool satisfactorily performed up to 10 minutes at dry condition.

Authors: Astacio Raquel , Ternero Fatima , Caballero Eduardo Sanchez , Montes Juan Manuel , Cuevas Francisco Gomez
Published: July 2018

Highly oxidized iron powders were consolidated by means of the medium-frequency electrical resistance sintering technique (MF-ERS). In order to activate the powders and to disperse the oxides coating the particles, prior to the consolidation process, powders were milled in a high-energy mill for 7 minutes. Structural and mechanical characterisations of electrically consolidated compacts were carried out in order to study the effect of two main processing parameters (current intensity and heating time). The compact properties resulted to be very sensitive to these parameters, especially to the current intensity. A change from 5 kA to 10 kA in the current intensity makes the porosity to fall from 30% to 8%. Moreover, using a higher current intensity (10 kA) increases the mechanical properties of the final compacts: micro-hardness change in almost 50 HV, up to 104 HV 1, and compression resistance by around 500 MPa, up to 569 MPa.

Authors: Tappanawatch Wapoon , Prapainainar Paweena , Sae-Oui Pongdhorn , Loykulnant Surapich , Dittanet Peerapan
Published: July 2018

Cellulose nanocrystals (CNC) were extracted from corn cob and synthesized by alkaline treatment using 3 wt% sodium hydroxide (NaOH). Acid hydrolysis with 64 wt% sulfuric acid (H2SO4) at different reaction times (30, 45, 60 min) was performed to obtain CNC solutions. CNC was evaluated as a reinforcing agent in natural rubber (NR) at CNC loadings from 1-5 wt%. Gamma-ray radiation was used as vulcanization method and varied at 10 and 20 kGy. The tensile modulus and tensile strength of NR vulcanizates increased with addition of CNC and contents. In addition, radiation by gamma ray impacts the mechanical performance, where CNC/NR composites vulcanized with higher dose of radiation of 20 KGy were found to have the higher values in tensile strength, elongation at break, and modulus than with 10 KGy. Moreover, the tensile strength and elongation at break of the composites after aging were found to slightly increase due to post-curing during the aging process.
Quality Improvement of CNT by Thermal Treatment and Enhancement of Properties of CNT/Polymer Composites
Authors: Amemiya Takashi , Yasuhara Toshiyuki
Published: July 2018

Since CNTs (carbon nanotubes) have excellent electrical and mechanical characteristics, their application as fillers for polymer matrix composites is expected to have great potential. The purpose of this study is to clarify the effect of CNT’s crystallinity quality, which is given by high temperature treatment (i.e. annealing), on the properties of CNT/polymer composites. In this study, double wall type CNT (DWNT) and multi wall type CNT (MWNT) were used and heat treated at up to 2000°C to achieve highly improved crystallinity. Electrical and mechanical properties of the CNT/polymer composites were compared with the various CNT’s crystallinity qualities as measured by ID/IG ratios. As a result, although the composites with higher quality CNTs showed considerably lower surface resistivities, however the same composites had lower Young's modulus and tensile strengths. The reason is thought to be that the high quality CNT has low surface activity and weak adhesion between the polymer and the CNT surface. This suggests that CNTs with higher quality do not always contribute to the improvement to the properties of CNT/polymer composites.
The Flexural Strength of Glass Fiber Reinforced Polyester Filled with Aluminum Tri-Hydroxide and Montmorillonite
Authors: Kaleg Sunarto , Ariawan Dody , Diharjo Kuncoro
Published: July 2018

Aluminum tri-hydroxide (ATH) and montmorillonite (MMT) are capable to enhance flame retardancy of glass fiber reinforced polymer (GFRP). Nevertheless, the combination of both flame retardant fillers on changes in the mechanical properties of GFRP is not yet known. The characterization of flexural strength and scanning electron microscope (SEM) observation on GFRP composite has been done. The result of flexural properties testing shows that the addition of ATH or MMT or a combination of both on the GFRP causes a decrease in flexural strength. GFRP with increased ATH loading causes an increase in elastic modulus. Contrarily, the MMT addition causes a decrease in the elastic modulus of the GFRP composite. SEM results on the fractured samples show that the high content of ATH or MMT in the UP tends to agglomerate thus showing visible holes that were formed from the filler particles pulled out from the matrix.
Sports Bettors: A Systematic Review
Authors: Mercier Jonathan , Sévigny Serge , Jacques Christian , Goulet Annie , Cantinotti Michael , Giroux Isabelle
Published: July 2018

Sports betting is associated with problematic gambling behaviours. However, little is known about the profile of sports bettors. Also, it is still unclear if there are useful abilities in sports betting. This systematic review aims to describe gambling habits and cognitions of sports bettors, and determine the roles of chance and skill in sports betting. Addressing the chance and skill distinction in sports betting would be helpful to identify which of sports bettors' cognitions are erroneous. Out of 991 studies identified in the databanks, 31 met the inclusion criteria of this review. Results indicate that these studies are mostly conducted with male samples aged from 30 to 50 years. These gamblers bet many times per week, with weekly averages ranging from 100 to 200$ CAD. Five studies examined the roles of chance and skill in sports betting, among which three showed that sports bettors perform better than chance in predicting results accurately, but they do not win more money than they would with a random selection, due to the structure of the game. The 11 studies that focused on cognitions indicate that sports bettors overestimate the influence of skill on the outcome of the game. These results support the need to further study the role of cognitions in the behaviours of sports bettors. It also offers insights concerning the distinction between chance and skill in sports betting.RésuméLes paris sportifs sont associés à des comportements de jeu problématiques. Cependant, on sait peu de choses sur le profil des parieurs sportifs. De plus, il est difficile de statuer si certaines habiletés seraient utiles dans les paris sportifs. Cette revue systématique vise à décrire les habitudes de jeu, les cognitions des parieurs sportifs, et à déterminer le rôle du hasard et des habiletés dans ces paris. Examiner la distinction entre le hasard et les habiletés aux paris sportifs serait utile afin de déterminer quelles cognitions entretenues par les parieurs sportifs sont erronées . Sur 991 études repérées dans les banques de données, 31 répondaient aux critères d’inclusion de cette revue. Les résultats indiquent que ces études sont principalement menées auprès d’échantillons masculins âgés de 30 à 50 ans. Ces joueurs parient plusieurs fois par semaine et misent  en moyenne de 100 $ à 200 $ CA par semaine. Cinq études ont examiné les rôles du hasard et des habiletés dans les paris sportifs, parmi lesquels trois ont montré que les parieurs sportifs prédisent mieux les résultats sportifs que le hasard, mais ils ne gagnent pas plus d’argent qu’avec une sélection aléatoire, en raison de la structure du jeu. Les onze études portant sur les cognitions indiquent que les parieurs sportifs surestiment l’influence des habiletés sur l’issue du jeu. Ces résultats confirment la nécessité d’approfondir le rôle des cognitions dans les comportements des parieurs sportifs. Ils donnent également des pistes sur la distinction entre le hasard et les habiletés dans les paris sportifs.

Published: July 2018

Abstract. Southern West Africa (SWA) is undergoing rapid and significant socioeconomic changes associated with a massive increase in air pollution. Still, the impact of atmospheric pollutants, in particular that of aerosol particles, on weather and climate in this region is virtually unexplored. In this study, the regional-scale model framework COSMO-ART is applied to SWA for a summer monsoon process study on 2–3 July 2016 to assess the aerosol direct and indirect effect on clouds and atmospheric dynamics. The modeling study is supported by observational data obtained during the extensive field campaign of the project DACCIWA (Dynamics–Aerosol–Chemistry–Cloud Interactions in West Africa) in June–July 2016. As indicated in previous studies, a coastal front is observed that develops during daytime and propagates inland in the evening (Atlantic inflow). Increasing the aerosol amount in COSMO-ART leads to reduced propagation velocities with frontal displacements of 10–30 km and a weakening of the nocturnal low-level jet. This is related to a subtle balance of processes related to the decrease in near-surface heating: (1) flow deceleration due to reduced land–sea temperature contrast and thus local pressure gradient, (2) reduced turbulence favoring frontal advance inland and (3) delayed stratus-to-cumulus transition of 1–2 h via a later onset of the convective boundary layer. The spatial shift of the Atlantic inflow and the temporal shift of the stratus-to-cumulus transition are synergized in a new conceptual model. We hypothesize a negative feedback of the stratus-to-cumulus transition on the Atlantic inflow with increased aerosol. The results exhibit radiation as the key player governing the aerosol affects on SWA atmospheric dynamics via the aerosol direct effect and the Twomey effect, whereas impacts on precipitation are small.
Description of a coastal impact event in Basque Country: the 9 February 2016 case
Authors: Gaztelumendi Santiago , Egaña Joseba , Liria Pedro , Aranda José A.
Published: July 2018

Abstract. In this work we analysed a case from 9 February 2016 from two points of view,
the meteorological–ocean characteristics of the event and the damage produced during
the episode in the Basque coastal area. On 7 and 8 February 2016
an intense zonal circulation was established in the Atlantic, with very strong
westerly winds (over 100 km h−1) and high fetch (more than 2000 km). As a
consequence a strong swell (over 7 m) arrived on the Basque coast affecting
littoral areas. The wave characteristics are particularly energetic during
the morning of the 9 February, which had a significant wave of 9.5 m and a peak period of
20 s in deep water (Donostia buoy). The arrival of these energetic waves
coincides with high tide during spring when the sea level reaches 4.69 m in the Port of Bilbao. Overtopping indexes exceeded red-level thresholds established
within the Euskalmet coastal warning system and the wave impact resulted in
relevant damage (more than EUR 3 million) in different littoral
areas. This event is the first red-level case since the new Euskalmet warning
procedure became operational at the beginning of 2015.
Paleoceanography and ice sheet variability offshore Wilkes Land, Antarctica – Part 2: Insights from Oligocene–Miocene dinoflagellate cyst assemblages
Authors: Bijl Peter K. , Houben Alexander J. P. , Hartman Julian D. , Pross Jörg , Salabarnada Ariadna , Escutia Carlota , Sangiorgi Francesca
Published: July 2018

Abstract. Next to atmospheric CO2 concentrations, ice-proximal oceanographic
conditions are a critical factor for the stability of Antarctic
marine-terminating ice sheets. The Oligocene and Miocene epochs
(∼ 34–5 Myr ago) were time intervals with atmospheric CO2
concentrations between those of present-day and those expected for the near
future. As such, these past analogues may provide insights into ice-sheet
volume stability under warmer-than-present-day climates. We present
organic-walled dinoflagellate cyst (dinocyst) assemblages from
chronostratigraphically well-constrained Oligocene to mid-Miocene sediments
from Integrated Ocean Drilling Program (IODP) Site U1356. Situated
offshore the Wilkes Land continental margin, East Antarctica, the sediments
from Site U1356 have archived the dynamics of an ice sheet that is today
mostly grounded below sea level. We interpret dinocyst assemblages in terms
of paleoceanographic change on different timescales, i.e. with regard to
both glacial–interglacial and long-term variability. Our record shows that a
sea-ice-related dinocyst species, Selenopemphix antarctica, occurs
only for the first 1.5 Myr of the early Oligocene, following the onset of full
continental glaciation on Antarctica, and after the Mid-Miocene Climatic
Optimum. Dinocysts suggest a weaker-than-modern sea-ice season for the
remainder of the Oligocene and Miocene. The assemblages generally bear strong
similarity to present-day open-ocean, high-nutrient settings north of the
sea-ice edge, with episodic dominance of temperate species similar to those
found in the present-day subtropical front. Oligotrophic and temperate
surface waters prevailed over the site notably during interglacial times,
suggesting that the positions of the (subpolar) oceanic frontal systems have
varied in concordance with Oligocene–Miocene glacial–interglacial climate
variability.
Deglacial to postglacial history of Nares Strait, Northwest Greenland: a marine perspective
Authors: Georgiadis Eleanor , Giraudeau Jacques , Martinez Philippe , Lajeunesse Patrick , St-Onge Guillaume , Schmidt Sabine , Massé Guillaume
Published: July 2018

Abstract. A radiocarbon dated marine sediment core retrieved in Kane Basin, central Nares Strait, was analysed to constrain the timing of the postglacial opening of this Arctic gateway and its Holocene evolution. This study is based on a set of sedimentological and geochemical proxies of changing sedimentary processes and sources that translate into ice sheet configuration in the strait. Proglacial marine sedimentation at the core site initiated ca. 9.0 cal. ka BP following the retreat of grounded ice. Unstable sea surface conditions subsisted until 7.5 cal. ka BP under the combined influence of warm atmospheric temperatures and proglacial cooling induced by the nearby Innuitian (IIS) and Greenland (GIS) ice sheets. The collapse of the ice saddle in Kennedy Channel at 8.3 cal. ka BP marks the complete opening of Nares Strait and the initial connection between the Lincoln Sea and northernmost Baffin Bay. Delivery of sediment by icebergs was strengthened between 8.3 and 7.5 cal. ka BP following the collapse of the buttress of glacial ice in Kennedy Channel that triggered the acceleration of GIS and IIS fluxes toward Nares Strait. The destabilisation in glacial ice eventually led to the rapid retreat of the GIS in eastern Kane Basin at 8.1 cal. ka BP as evidenced by a noticeable change in sediment source in our core. The gradual decrease of carbonate inputs to Kane Basin between 8.1 and 4.1 cal. ka BP reflects the late deglaciation of Washington Land. The shoaling of Kane Basin can be observed in our record by the increased winnowing of lighter particles as the glacio-isostatic rebound brought the seabed closer to subsurface currents. Our dataset suggests reduced iceberg delivery from 7.5 to 1.9 cal. ka BP in relation to the Neoglacial cooling that likely enhanced sea ice occurrence, thus suppressing calving and/or the drifting of icebergs in Nares Strait.

Abstract. Salt marsh ecology classification is difficult using traditional coarse resolution remote sensing techniques. Salt marshes exhibit a spatial pattern of vegetation zonation that are visually identifiable using imagery that has an improved 0.04 meter per pixel resolution. This project applies high resolution unmanned aerial system (UAS) imagery to aid in multi-temporal classification of our study area (Horseneck Beach) in Westport, Massachusetts, USA. We flew a DJI Phantom Pro 3 at low- and high-tide to capture effects the changing tide has on vegetation in an effort to predict effects of the rising sea level on saline plant species. We implement an open source software workflow using OpenDroneMap and the Semi-Automatic Classification Plugin for QGIS to create the necessary orthomosaics and to conduct vegetation classification required of this project. We compare land cover classifications using one-time-point RGB imagery to a multi-time-point (low tide, high tide) RGB image stack to investigate whether the multi-time point stack improves land cover classification accuracy. We find it does. More generally, this paper provides a model for others wishing to use low-cost UAS equipment carrying a simple low-cost RGB camera, and free and open source for geospatial (FOSS4G) tools, to develop multi-band image stacks to improve land cover classification accuracy. Further, we provide some reflections and technical notes on our experience. The approach we present here could be extended to include other image layers that UAS can provide when equipped with other sensors, such as multi-spectral (e.g., NIR, thermal), or by adding another band with photogrammetry-produced digital elevation data.

Abstract. Arctic landfast sea ice has undergone substantial changes in recent decades affecting ice stability with potential impacts on ice travel by coastal populations and industry ice roads. The role of landfast ice as an important habitat has also evolved. We present a novel approach to evaluate sea ice stability on a pan-Arctic scale using Synthetic Aperture Radar Interferometry (InSAR). Using Sentinel-1 images from spring 2017, the approach discriminates between bottomfast, with critical relevance for subsea permafrost, as well as stabilized and non-stabilized floating landfast ice over the main marginal seas of the Arctic Ocean (Beaufort, Chukchi, East Siberian, Laptev and Kara Seas). The analysis draws on evaluation of small-scale lateral motion derived from relative changes in interferometric fringe patterns. This first comprehensive assessment of Arctic bottomfast sea ice extent revealed that by area most of the bottomfast sea ice is situated around river mouths and coastal shallows in the Laptev and East Siberian Seas, covering roughly 4.1 and 5.5 thousand km2 respectively. The fraction between non-stabilized and stabilized ice is lowest in the Beaufort at almost unity, and highest in the adjacent Chukchi Sea. Beyond the simple delineation of landfast ice zones, this work provides a new understanding of how stability regimes may vary between regions and over time. InSAR-derived stability data may serve as a strategic planning and tactical decision-support tool for different uses of coastal ice. Such information may also inform assessments of important sea ice habitats. In a case study, we examined an ice arch situated in Nares Strait demonstrating that interferograms may reveal early-warning signals for the break-up of stationary sea ice.
A Stylistic Analysis of Divine-Prophetic Discourse in Biblical and Quranic Texts
Authors: Al-Ameedi Riyadh Tariq Kadhim , Mehdi Manar Kareem
Published: July 2018

This paper attempts to identify the stylistic aspects of the language utilized in Divine-Prophetic discourse in Biblical and Quranic texts. Precisely, this work sets itself the task of answering the following question: what are the most prevalent stylistic devices implemented in this kind of discourse? Accordingly, the study aims at identifying the most common stylistic devices employed in Divine-Prophetic discourse and finding the interdifferences between Biblical and Quranic texts in this respect. It is hypothesized that Divine-Prophetic discourse utilizes certain stylistic techniques such as parallelism, repetition, alliteration, rhyme, simile, and metaphor. In order to achieve the aims of this paper and test its hypothesis, Leech and Short's (2007) categorization of figures of speech is utilized for the analysis of the data under scrutiny. Besides, a statistical method represented by the percentage equation is utilized for calculating the findings of analysis. The analysis is conducted on three Biblical texts taken from different books of the Old Testament and three Quranic texts taken from different suras of the Glorious Quran. Findings of the analysis reveal that the above hypothesis has been partially validated in the Biblical texts in that parallelism, repetition, alliteration, and simile have been widely implemented in these texts whereas rhyme and metaphor are not used at all. The same hypothesis, however, has been fully validated in the Quranic texts.
Middle Kingdom tombs from Asasif: work in the 2015/2016 season
Authors: Chudzik Patryk
Published: July 2018

In the third season of the Polish Asasif Project at the North Asasif Necropolis in West Thebes archaeological fieldwork concentrated on six of the Middle Kingdom rock-cut tombs: MMA 508/TT 311, MMA 509, MMA 512, MMA 514, MMA 515 and MMA 517/TT 240. The corridors and chambers were cleared and the architecture documented and restored. A surface survey was carried out on the slope. Of greatest interest among the finds are Middle Kingdom stonemason’s tools and cartonnages from the Third Intermediate Period.

The paper presents a selection of cooking ware pottery excavated in 2014 and 2016 from the fill under the central and eastern parts of the main courtyard (1) of the “Hellenistic” House in Nea Paphos–Maloutena. Most of the studied vessels are of early Roman date and, for the most part, Cypriot production, although there is a spattering of imports from the Aegean, Italy, the Levant and Egypt.
Preliminary report on a new prehistoric site in northern Oman (Qumayrah/Ayn 2)
Authors: Białowarczuk Marcin
Published: July 2018

This paper reports briefly on the results of a short reconnaissance at the site of Qumayrah–Ayn 2 (QA 2), a new prehistoric site located in a poorly studied part of the Qumayrah Valley in northern Oman. A survey and limited probing by the Omani–Polish Qumayrah Archaeological Project confirmed the presence of a sediment, approximately 15–20 cm thick, which yielded not just lithics, but also stone installations discovered in situ. One of these installations was evidently a hearth, the other a kind of platform. The lithic assemblage is characterized by a prevalence of flake technology with rare blade products. Predominant in the tools group are side-scrapers, notches and perforators produced by direct-scaled retouch. The most characteristic tools are tanged projectile points made on flakes. The main problem is contextualizing these materials. On the grounds of certain premises they may be associated with the Fasad technocomplex, but not necessarily the pre-Neolithic one as is the case of the classic types. However, a much later chronology is also quite possible.
Kuršių nerijos nacionalinio parko paveldo būklės vertinimas

Published: July 2018

Straipsnyje, remiantis natūrinių stebėjimų metu surinktais duomenimis, pateikta kompleksinės Kuršių nerijos nacionalinio parko paveldo būklės analizė. Visapusiškam paveldo būklės ištirtumui užtikrinti, įvertinta atskirų gamtos ir kultūros paveldo objektų dabartinė situacija, palyginta su skirtingų metų kultūros paveldo objektų būklės duomenimis. Nustatyta, kad dviejų iš 11 gamtos paveldo objektų situacija nuolatos blogėja, o 24 % kultūros paveldo objektų padėtis šiuo metu yra pablogėjusi. Remiantis paveldo objektų būklės duomenimis, išskirti trys probleminiai arealai, kurie mažina tarptautiniu mastu saugomo kultūrinio kraštovaizdžio paveldo vertę. Pagrindinės priežastys, lemiančios Kuršių nerijos nacionalinio parko paveldo būklės blogėjimą, – nuolatinės stebėsenos nevykdymas, tarpinstitucinio bendradarbiavimo trūkumas, rekreacinė digresija, teisinio apsaugos statuso nepakankamumas. Komplek­sinio pobūdžio paveldo būklės tyrimai saugomose teritorijose yra reikšmingi teoriniu aspektu – renkant duomenis apie atskirų paveldo objektų būklę; praktiniu aspektu – formuojant prioritetines paveldo tvarkybos kryptis ir teikiant pasiūlymus tvarkymo planų zonų ribų korekcijoms.
La escena como posible mediadora y propulsora de nuevas políticas en el contexto de la diáspora del pueblo sirio
Authors: Martínez López Carolina
Published: July 2018

Utilizando formal y conceptualmente las etapas del viaje, el presente artículo analiza desde un punto de vista ético, político y artístico las propuestas escénicas más representativas que en Europa y Oriente Próximo han abordado en los últimos años y mediante fórmulas diversas el fenómeno de la diáspora siria. El objetivo principal radica en analizar la capacidad de estas manifestaciones como generadoras de nuevas relaciones y realidades, tomando la idea de Althusser de que la cultura no refleja, sino que produce la sociedad, y que entroncaría con los orígenes del teatro documental y político en Brecht y Piscator. Asimismo, se analiza cómo se pueden presentar y representar la realidad y la otredad sin una mirada colonial, patriarcal o proteccionista, y cómo enfrentarse a los problemas éticos derivados de este tipo de prácticas, para que la escena pueda mediar en la creación de nuevas formas de estudiar a las personas en tránsito físico e identitario (McDowell) y que se plantee como un “tercer espacio” (Bhabha), desde el que poder trazar una nueva política en relación al yo y al otro.
