Published: November 2019

El objetivo del estudio fue evaluar el efecto de diferentes mezclas de N-P-K en el crecimiento y desarrollo del híbrido de maíz 19-10 (FENALCE). La investigación se realizó en la Finca “La Granja” vereda Arguello Bajo, Municipio de Yacuanquer (Nariño, Colombia). Se utilizó un diseño de bloques completos al azar, con tres repeticiones y ocho tratamientos correspondientes a dosis de  N,P,K, (302 kg.ha-1 de Urea, 483 kg.ha-1 de DAP, 185 kg.ha-1 KCl, y sus combinaciones) y un testigo sin fertilizante. Las variables evaluadas, fueron altura de planta (PH), peso fresco (FW) y seco (DW) de la planta (raíz, tallo, hojas), Phylochromia (FER), diámetro de tallo (SD), número de hojas (NH) y rendimiento de grano (Y). Se presentaron diferencias significativas en las variables, PH, SD, FW, NH; DW de raíz y rendimiento de grano (Y) entre tratamientos. La Phylochromia osciló entre 3,8 y 1,1 días, valores para el testigo y la aplicación de N y K, respectivamente. La Phylochromia, disminuyó cuando se acercó la aparición de la inflorescencia, (masculina y femenina), variando en el tiempo para cada tratamiento, entre 2,6 y 1,1 días, donde el T5 (N, K) tuvo mayores valores al inicio del cultivo y el menor al final de la aparición de la inflorescencia, lo que pudo determinar el rendimiento de los tratamientos. La aplicación de N K, fue significativamente mayor en PH (190,6 cm), SD (7,55 cm), FER y rendimiento (6,99 t ha-1), seguido por la aplicación de la mezcla de N, P y K con 6,28 t ha-1, el menor rendimiento se presentó con el testigo (4,16 t ha-1), seguido de la aplicación de N (4,42 t ha-1); de la misma forma NH osciló entre 11,3 (Testigo) y 16,7 para la aplicación de N, K (T5). La formación fisiológica de la inflorescencia masculina (40 días después de siembra) y femenina (60 días después de siembra), afecto todos los órganos de la planta, lo que se reflejó en la curva de crecimiento y desarrollo de la planta.

Published: November 2019

English as a global language has been used widely in various communication modes. The communication in the automotive industry is highly characterized as technical therefore, it possesses certain features that may be exclusive to its communication type. Since today’s time veers on amalgamating World Englishes, this discourse analysis study investigates the stylistic features of Philippine English and Singaporean English.Three pairs of automotive review articles written by Filipino and Singaporean writers were subjected to compare and contrast the stylistic features of these two English varieties. The findings reveal that Philippine English and Singaporean English used in automotive communication are similar in terms of register, grammatical feature, and writer’s style. On the other hand, the two varieties differ in terms of article contents and conventions. The study has implications in the creation of curriculum in automotive engineering that emphasizes both technology teaching and language teaching.
Evaluation of EFL Textbook ‘Traveller Elementary’ from the Perspectives of Instructors and University Students
Authors: CESUR Kürşat , ÖZİŞLER Narin
Published: November 2019

Undoubtedly, foreign language teaching intends to make students obtain the required competence so as to get the linguistic knowledge needed in a foreign language. With this respect, a textbook should supply to the users as much as possible, be satisfactory to fit into the syllabus, and meet all the needs and expectations of the students during the learning process in order to achieve required targets in foreign language learning. Particularly in English Language Teaching, textbooks as the basic instructional materials are expected to build learners’ four skills that are speaking, listening, reading and writing. Depending on this basic assumption, this study attempts to get in-depth evaluation of the textbook in terms of methodology and language content, language skills, practicality, topic, social and cultural values by taking into consideration university first year students and their instructors’ evaluations, observations, beliefs, and suggestions on the textbook. From the students’ perspectives, results reveal that the textbook is moderately efficient in terms of methodology and language content, language skills, practicality, topic, social and cultural values; however, instructors find some parts of the textbook weak; especially some aspects of language skills, practicality, social and cultural values. As a result, the textbook is neither completely insufficient nor perfectly adequate. At the end of the study some suggestions for instructors and material writers are provided.
MicroRNA-561 Affects Proliferation and Cell Cycle Transition Through PTEN/AKT Signaling Pathway by Targeting P-REX2a in NSCLC
Authors: Liao ZiJun , Zheng Qi , Wei Ting , Zhang YanBing , Ma JieQun , Zhao Zheng , Sun HaiFeng , Nan KeJun
Published: November 2019

MicroRNAs (miRNAs) play crucial roles in tumorigenesis and tumor progression. miR-561 has been reported to be downregulated in gastric cancer and affects cancer cell proliferation and metastasis. However, the role and underlying molecular mechanism of miR-561 in human non-small cell
lung cancer (NSCLC) remain unknown and need to be further elucidated. In this study, we discovered that miR-561 expression was downregulated in human NSCLC tissues and cell lines. The overexpression of miR-561 inhibited NSCLC cell proliferation and cell cycle G1/S transition and
induced apoptosis. The inhibition of miR-561 facilitated cell proliferation and G1/S transition and suppressed apoptosis. miR-561 expression was inversely correlated with P-REX2a expression in NSCLC tissues. P-REX2a was confirmed to be a direct target of miR-561 using a luciferase
reporter assay. The overexpression of miR-561 decreased P-REX2a expression, and the suppression of miR-561 increased P-REX2a expression. Particularly, P-REX2a silencing recapitulated the cellular and molecular effects observed upon miR-561 overexpression, and P-REX2a overexpression counteracted
the effects of miR-561 overexpression on NSCLC cells. Moreover, both exogenous expression of miR-561 and silencing of P-REX2a resulted in suppression of the PTEN/AKT signaling pathway. Our study demonstrates that miR-561 inhibits NSCLC cell proliferation and G1/S transition and
induces apoptosis through suppression of the PTEN/AKT signaling pathway by targeting P-REX2a. These findings indicate that miR-561 plays a significant role in NSCLC progression and serves as a potential therapeutic target for NSCLC.
Karyotype of Polyommatus (Agrodiaetus) eriwanensis Forster, 1960 and taxonomic position of P. (A.) interjectus de Lesse, 1960 (Lepidoptera, Lycaenidae)
Authors: Lukhtanov Vladimir , Dantchenko Alexander
Published: November 2019

The karyotype of Polyommatus (Agrodiaetus) eriwanensis Forster, 1960 from the type locality (“Eriwan” [Yerevan, Armenia]) and other localities in Armenia was investigated. The number of chromosomal elements (bivalents+ multivalents) observed in male meiosis I was found to vary from 29 to 34. In individuals with n = 34, all observed elements were represented by bivalents. In other specimens, heterozygosity for different number of chromosomal fusions resulted in multivalent formation at MI stage and consequently in a lower number of recognizable chromosomal elements. We show that all karyotype peculiarities of P. (A.) interjectus de Lesse, 1960 (n = 29–32) from Turkey are similar to those in A. eriwanensis. The butterflies of these taxa have allopatric distribution and can be considered as conspecific.
Composition patterns of ornamental flora in the Czech Republic
Authors: Petřík Petr , Sádlo Jiří , Hejda Martin , Štajerová Kateřina , Pyšek Petr , Pergl Jan
Published: November 2019

Ornamental plants are an important component of urban floras and a significant source of alien plant invasions to the surrounding landscapes. We studied ornamental flora across 174 settlements in the Czech Republic, Central Europe. The aims of the study were to (i) identify clusters of sites that are defined as distinctive groups of ornamental taxa reflecting environmental or socioeconomic factors and (ii) apply the classification approach which is traditionally used for spontaneous vegetation in order to evaluate the potential of different settlement types to act as source sites of invasive species. The inventories were classified in a similar manner that is generally applied to spontaneous vegetation using the COCKTAIL method. Diagnostic taxa were classified in a repeatable manner into 17 species groups, forming five distinctive clusters with ~70% of sites attributed to one cluster. The species pools of the clusters differed in their representation of species with native or alien status and different life forms. The following clusters were distinguished, based on the prevailing type of settlement: (1) old villas neighbourhoods of towns, (2) upland settlements, (3) modern neighbourhoods, (4) old rustic settlements and (5) modern rustic settlements. Similar to spontaneous vegetation, the classification of ornamental flora reflects both basic natural gradients (i.e. altitude) and man-made factors (i.e. the preferences for certain plants and associated management practices). Alien taxa associated with modern neighbourhoods are characterised by a relatively higher invasion potential than those from, for example, old rustic settlements. This is especially true for woody species which can spread in ruderal habitats as a result of urban sprawl. Our results showed that the classification method, commonly used to analyse vegetation data, can also be applied to ornamental flora.
L’idée d’une science du design : trois concepts et leurs implications
Authors: Michaud Yves
Published: November 2019

L’article propose une vue conceptuelle de trois tentatives d’élaboration d’une science du design en montrant que celles-ci sont tributaires aussi bien d’une conception de la science à une période donnée que des vicissitudes du concept de design. Les versions de la science en question sont celle d’une science du design ornemental, celle d’une science du design matériologique, celle d’une science du design comme pensée de la production d’un projet complexe. Avec finalement quelques doutes que l’on puisse parler d’autre chose que de science pratique. Ces approches ont néanmoins le bénéfice de montrer quels traits du design une science du design laisse de côté.

Published: November 2019

En revenant sur les objections fréquemment adressées à la recherche-création, l’auteure les oppose à une vision critique du développement scientiste d’une partie de la recherche en design. L’article propose de questionner la qualité du design produit dans le cadre de démarches de recherche ainsi que sa portée épistémologique. Il introduit une comparaison avec certaines prises de position en faveur d’une écriture littéraire des sciences humaines. Un programme de recherches possibles conclut la démonstration.
De l’ethnographie au design, du terrain à la création : tactiques de traduction
Authors: Nova Nicolas , Léchot Hirt Lysianne , Kilchör Fabienne , Fasel Sébastien
Published: November 2019

La notion de design centré-utilisateur renvoie aux approches de conception de produits, d’interfaces et de services potentiellement mieux adaptés aux personnes susceptibles de les utiliser. À cet effet, l’ethnographie, dans sa dimension méthodologique liée à l’étude de terrain, a été mobilisée par des designers. Or, si les démarches d’observation et d’entretien sont bien documentées dans la littérature, les manières d’utiliser le matériau produit dans un contexte de création sont rarement abordées. En s’appuyant sur une étude réalisée auprès de designers d’interaction, cet article aborde la traduction des résultats du terrain dans le projet de design.
Design et innovation : deux faces d’une même médaille ?
Authors: Kahane Bernard
Published: November 2019

Design et innovation sont deux termes qui, de manière fréquente, font sens au sein de la presse d’actualité généraliste et qui constituent des champs d’interrogation et d’investigation pour les praticiens, les politiques, les experts et les académiques. Dans ce contexte de ce que sont, du point de vue de leur réalité et de leurs perceptions, l’innovation d’une part, le design d’autre part, cet article analyse ces deux activités et leur croisement. Il les replace ainsi dans leurs significations multiples et globales et s’interroge sur le sens qu’elles peuvent revêtir l’une pour l’autre. Il les utilise ensuite pour montrer comment design et innovation interviennent de concert, et propose ainsi une grille de lecture interprétative commune illustrée au travers de l’exemple du développement des téléphones tactiles.
Design, agilité et intelligence collective : motifs et conséquences d’une mutation des pratiques
Authors: Serrault David
Published: November 2019

Les forces conjointes du déclin industriel et de l’essor du numérique questionnent les pratiques du design. Cet article propose de mettre en regard l’incidence de la postmodernité sur le design avec celle de la modernité sur les arts plastiques. Prenant acte de l’importance économique croissante des technologies de l’information et de la communication, ainsi que des spécificités du travail de la matière calculée et des services, nous observons un élargissement du champ des pratiques dans deux directions. La première, orientée vers le faire par l’adhésion aux méthodes de développement dites « Agiles », la seconde vers des espaces du projet au sein desquels l’enjeu réside moins dans la réalisation de formes que dans la facilitation de leur émergence.
À quoi tient le design : un entretien avec Pierre-Damien Huyghe
Authors: Kazi-Tani Tiphaine , Huyghe Pierre-Damien
Published: November 2019

Si le design peine toujours à se faire la place, légitime, qui est pourtant la sienne historiquement, en tant que socialisation de productions non issues de la tradition (Stiegler et Geel, 2004), qu’agent d’amélioration de l’habitabilité du monde (Findeli, 2005), de condition suivant laquelle les techniques de l’époque seront amenées à rendre ce qu’elles peuvent de mieux (Huyghe, 2015), l’époque quant à elle, ne cesse d’invoquer le design, d’appeler son nom. Philosophe, Pierre-Damien Huyghe s’explique avec les mots, méthodiquement et rigoureusement, interroge ce qu’ils contiennent en puissance, et réalisent en acte. Car en tant qu’ils administrent des régimes de vérités, il est donné, sans condition, à certains mots le pouvoir d’agir dans le monde. À partir de l’évocation de ses travaux récents, et notamment son ouvrage À quoi tient le design , nous proposons d°interroger notamment la position contemporaine du design face à l’industrie, le design en tant que tension et résistance, le caractère problématique d’une injonction indiscutée à l’innovation.
Entre rues et réseaux : exploration de nouveaux dispositifs de communication dite participative
Authors: Bahuaud Myriam , Pecolo Agnès
Published: November 2019

L’objectif est, dans le cadre d’opérations de communication qui investissent les rues (dont les flash mobs), de souligner la rencontre entre Technique (capacités technologiques) et Humanité (supposée en attente d’interactions), entre le corps physique (chair et contact) et le corps virtuel (communautés numériques). L’analyse de ces dispositifs de communication, orchestrés on et off line , invitant le citadin à vivre l’espace public sur un mode immersif et éphémère, met à jour les prolongations réciproques entre les espaces urbain et virtuel, prolongations symptomatiques d’un double processus d’ hyperpublicitarisation et de dépublicitarisation . Les stratégies de communication prenant la ville pour média, produisent un univers festif et spectaculaire, ludique et créatif et posent la participation du public (partenaire) comme impérative. Il reste pourtant à tester la réalité sociale et l’assise idéologique d’une collaboration vantée par le milieu professionnel en communication étudiée ici.
Des humains dans la machine : la conception d’un algorithme de classification sémantique au prisme du concept d’objectivité
Authors: Schmitt Églantine
Published: November 2019

Un algorithme est le résultat de la formalisation d’une procédure qui, une fois implémentée dans un programme informatique, peut alors être rejouée indéfiniment sans intervention. La matérialité sociotechnique des programmes les inscrit dans des systèmes de contingences, de normes et d’habitudes, qui laissent la capacité d’action humaine au cœur du processus. Ni le caractère mécanique des programmes, ni la cohérence structurale de leurs fondements mathématiques, ne leur permettent de produire de l’objectivité par eux-mêmes. Elle provient de l’expertise de leurs concepteurs qui travaillent, soit par échange direct, soit par le biais d’outils d’évaluation, en interaction avec les utilisateurs bénéficiaires dont l’appréciation valide pragmatiquement les produits des algorithmes. C’est, en somme, le design des programmes par succession de choix humains qui fait d’eux des machines à produire des connaissances.
Les formes d’innovation publique par le design : un essai de cartographie
Authors: Weller Jean-Marc , Pallez Frédérique
Published: November 2019

Depuis une dizaine d’années, les services publics introduisent des démarches d’innovation d’un genre inédit, rompant formellement avec les réformes managériales jusqu’alors déployées. Si les formes concrètes que peuvent prendre ces initiatives semblent variées, elles n’en investissent pas moins des techniques partageant un même air de famille et se placent volontiers sous la bannière du « design de service ». Mais selon quelles modalités ? Sur la base de quelles problématiques ? Avec quelles visées et quel contenu ? Dans le cadre d’un projet ANR de recherche entièrement consacré à ces nouvelles formes d’innovation publique (FIP), les auteurs de cet article se proposent de brosser à grands traits les contours de ce paysage inédit. En recensant plus de 200 cas menés depuis les dix dernières années dans des institutions publiques très diverses, l’enjeu est ici de fournir aux lecteurs un descriptif du phénomène d’émergence de ces innovations « par le design », depuis lequel quatre types de FIP sont mises en évidence.
Au nom de l’usager : co-concevoir la relation au public dans une mairie
Authors: Özdirlik Burcu , Pallez Frédérique
Published: November 2019

La relation à l’usager et son amélioration sont des thématiques rebattues de l’action publique. Différents axes de transformation de la relation de service ont été explorés depuis 25 ans, mais la question de la co-conception des services publics apparaît maintenant comme essentielle. Or se développent des démarches d’« innovation publique par le design », dont une des promesses est de redonner à l’usager une place centrale dans le processus de conception. Quelle est cette place ? Quelle construction des publics opèrent ainsi ces démarches ? Comment qualifier l’innovation résultant de ces processus ? A travers l’analyse approfondie d’une de ces expériences, nous montrons que ces démarches travaillent plus sur des situations d’usage que sur des usagers, et que ces situations d’usage ne sont pas nécessairement issues du terrain investigué. Les projets les plus innovants construisent des situations d’usage inédites qui mettent en scène des figures et des postures d’usager nouvelles. L’usager « réel » serait-il un obstacle à l’innovation publique ?
Échelles et raisons d’agir dans la conception architecturale
Authors: Raynaud Dominique
Published: November 2019

Cet article compare les modèles explicatifs en architecturologie et en philosophie analytique de l’action, l’une et l’autre postulant l’existence d’actions finalisées. Cette similitude pose la question de l’identité des échelles de référence et des raisons d’agir. On montre que les échelles sont un sous-ensemble des raisons d’agir. Ce résultat a deux conséquences : 1. Le pouvoir explicatif des raisons d’agir est supérieur à celui des échelles de référence. 2. Raisons d’agir et échelles de référence ont un intérêt pour l’explication ex post du travail de conception. D’où l’orientation de l’« opératoire pur » défendue ici, qui consiste à abandonner les raisons d’agir aux concepteurs pour se concentrer sur la description des opérations de conception par des schèmes d’action.
Les marches urbaines exploratoires de nuit : une critique socio-urbaine en situation
Authors: Guérin Florian , Hernández González Edna
Published: November 2019

Dans cet article, nous voulons consolider l’hypothèse selon laquelle le renouvellement de la critique socio-urbaine systématisée de la société contemporaine est parallèle au développement des travaux sur la marche urbaine comprise comme « fait social total » (Mauss, 1923-24). La marche urbaine, en tant qu’expérimentation méthodologiquement cadrée, permettrait un regard in situ sur la ville, amenant à une réflexivité critique sur l’aménagement urbain, face au vécu, au subversif et aux sens (ontologique et perceptifs) de ses usagers. Il nous faudra démontrer que cette articulation fructueuse permet une compréhension complexe de l’urbanité nocturne occidentale. La méthodologie des Marches urbaines exploratoires de nuit est basée sur un large corpus comprenant les diagnostics urbains (en marchant ; explorations de Armengaud, 2013 et Gwiazdzinski, 2006), les critiques du mouvement moderne (Debord et ses dérives urbaines, 1958 ; Augoyard, 2010) et les explorations urbaines sensibles (démarches de Thibaud et Grosjean, 2001 ; cartes mentales ; etc.).
Le design management dans les PME : une cartographie pour diagnostiquer les pratiques
Authors: Glaubert Daphna , Nyffeler Nathalie , Bergeron Luc
Published: November 2019

Le design est une démarche de création de valeur qui favorise l’innovation au sein des organisations. Au-delà de cette évidence, de nombreuses PME peinent à l’intégrer au sein de leurs pratiques. En effet, le design est une notion à visages multiples dont la mise en application reste abstraite. Cet article aborde les questions suivantes : Comment caractériser la pratique actuelle du design management au sein des PME ? Comment identifier les opportunités d’amélioration ? Pour y répondre, nous avons élaboré un outil permettant de cartographier le niveau d’intégration du design dans l’entreprise selon différents leviers. La recherche a été conduite au sein de trois PME et d’une start-up. La cartographie représente cinq leviers du design management . Elle permet de visualiser les pratiques actuelles et d’entamer un dialogue avec les parties prenantes. Suite à l’analyse, la création d’outils correspondant aux différents niveaux d’intégration du design management pourra faciliter sa pratique au sein de l’organisation.
Le design fantomatique des communautés savantes : enjeux phénoménologiques, sociaux et politiques de trois formats de données en usage dans l’édition scientifique contemporaine
Authors: de Mourat Robin
Published: November 2019

Dans le système de la communication scientifique contemporaine, les communautés savantes se voient organisées par un régime global d’éditorialisation dans lequel les pratiques éditoriales s’attachent à concevoir des flux de transformations plutôt que des artefacts particuliers à la forme prédéfinie. Dans ce contexte, les formats de données numériques agissent comme les passeurs et les prescripteurs d’un champ de possibilités esthétiques, sémiotiques et épistémologiques. Ils définissent ce qui peut être écrit, lu et manipulé, et ce faisant agissent sur la constitution des collectifs humains et non humains qui les utilisent. Cette contribution propose d’étudier l’action des formats sur les modes de fréquentation des travaux de recherche et l’influence de ces derniers dans la constitution des communautés savantes contemporaines, en analysant les implications phénoménologiques, sociales et politiques de formats numériques en usage dans les pratiques d’édition scientifique : TeX, XML/TEI, et Markdown.

Facilitating Empowerment and Stimulating Scholarly Dialogue Using the World Café Model

Student empowerment is the best vehicle for critical thinking and optimal learning, and enhances the development of nurses with the knowledge and skills required to navigate their way through the complex, shifting terrain of current nursing practice. Central to this process is scholarly dialogue, in which conversations are guided by an understanding of the state of the science in nursing. When conducted within the context of respect, such dialogue leads to student empowerment. Freire (2000) called such an approach to teaching a liberation pedagogy, in which professors are no longer the only source of knowledge in the classroom but rather help students move from being passive recipients to active creators of knowledge and ideas.

Concept Mapping as a Group Learning Activity in Graduate Nursing Education

The concept map is recognized as a teaching strategy that promotes critical thinking because it stimulates deep understanding. Students work through the process of organizing, analyzing, and communicating interrelationships among concepts through a visual representation of components. Concept maps have been widely reported in the literature as a teaching strategy in undergraduate education, particularly in clinical courses, with an application of planning or explaining patient care (Ignatavicius, 2004). However, the literature does not report the use of concept maps with graduate nursing students. [more...]

This new occurrence could be employed as an additional biostratigraphic tool for international correlation of the terminal Ediacaran, as well as for palaeobiogeographic and palaeoecologic reconstructions.
Updated stratigraphic framework and biota of the Ediacaran and Terreneuvian in the Alcudia-Toledo Mountains of the Central Iberian Zone, Spain
Authors: Álvaro J. J. , Cortijo I. , Jensen S. , Lorenzo S. , Pieren A. P.
Published: November 2019

An updated stratigraphic subdivision of the Ediacaran and Terreneuvian in the Alcudia valley and the Toledo Mountains, Central Iberian Zone, is documented here. The Lower Alcudian-Domo Extremeño Supergroup is subdivided, from bottom to top, into the conformable Guadiana (La Coronada and Sta. Mª de Zújar formations) and Campanario (Botija, Monroy and Orellana formations) groups. The supergroup contains biostratigraphically non-significant bacterial acritarchs and dubious fossils, but its Ediacaran age is constrained by detrital zircon analyses. This siliciclastic sedimentary package is unconformably overlain by either the siliciclastic-carbonate Ibor Group (Castañar, Villarta and Arrocampo formations) or the siliciclastic Cíjara Formation. The fossil content of the former group includes Sabelliditids, Vendotaenids, macrophytes, bioaccumulations and reefs rich in Cloudina, Sinotubulites, Protolagena and stromatolites and thrombolites, and a wide diversity of ichnofossils; whereas the Cíjara Formation has yielded bacteria attributed to Bavlinella and Palaeogomphosphaeria, and simple trace fossils (Gordia, Helminthoidichnites and treptichnids). The Ediacaran-Cambrian boundary, based on ichnofossils, lies at the base of the Arrocampo Formation and the uppermost part of the Cíjara Formation. In the Alcudia valley, the Ibor Group is subdivided into another three-fold, lithologically equivalent subdivision, known as the Tamujar, Hinojosas (rich in ichnofossils, such as treptichnids, Monomorphichnus, Psammichnites and Taphrelminthopsis) and Cabezarrubias (including Bergaueria and Planolites) formations. Another unconformity, intra-Fortunian in age, marks the tops of the Ibor Group and the Cíjara Formation, wich are subsequently overlain by the San Lorenzo Formation and some megabreccia beds, respectively. Overlying the slope-related Fuentes, Membrillar and Navalpino megrabreccia beds, the Terreneuvian-Cambrian Series 2, heterolithic Pusa Formation is subdivided into thre members, the middle one characterized by the record of phosphate ore deposits (e.g., the Fontanarejo Bed). The formation is shale dominated and has yielded the body-fossil Beltanelliformis and numerous ichnofossils (Monomorphicnus and Treptichnus; lower member), sponge spicules associated with thrombolites (middle member), and Scenella, trilobites, archaeocyaths and ichnofossils (Dactyloidites, Psammichnites, Rusophycus and Teichichnus; upper member). Where the megabreccia beds are absent, the Ibor Group is unconformably overlain by the San Lorenzo and Fuentepizarra formations, the latter containing phosphatic limestone interbeds rich in skeletonized microfossils, such as Anabarella, which represents the Fortunian-Cambrian Stage 2 boundary interval.
COGARCH Models
Authors: Arı Yakup
Published: November 2019

In this chapter, the features of a continuous time GARCH (COGARCH) process is discussed since the process can be applied as an explicit solution for the stochastic differential equation which is defined for the volatility of unequally spaced time series. COGARCH process driven by a Lévy process is an analogue of discrete time GARCH process and is further generalized to solutions of Lévy driven stochastic differential equations. The Compound Poisson and Variance Gamma processes are defined and used to derive the increments for the COGARCH process. Although there are various parameter estimation methods introduced for COGARCH, this study is focused on two methods which are Pseudo Maximum Likelihood Method and General Methods of Moments. Furthermore, an example is given to illustrate the findings.
Making Language Learning More Inclusive
Authors: Bobadilla-Pérez María , Fraga Viñas Lucía
Published: November 2019

This chapter presents the results of a study conducted in a language classroom in Galicia (Spain). The course was sponsored by the local administration and addressed to unemployed students (n = 14; average age 47). The education in foreign languages of the participants in the ‘80s and ‘90s had been held back due to curricular needs to promote the use of the second official language, Galician. The extrinsic motivation for English language learning of the participants was their need to improve linguistic skills to re-gain access to the job market. It was observed that they were consistently underperforming during writing exam preparation tasks. In order to meet the needs of these students, it was decided to study the impact that the explanation of the assessment rubric had on learners' written production. Results of their performance in a pre-test were compared to the results in a post-test. The implementation of this strategy proved to be effective. By allowing the students to have knowledge of the rubric for the assessment of their writings, their fear was significantly reduced.

Published: November 2019

Neste trabalho foi deduzida teoricamente a velocidade de deriva, o deslocamento e a mobilidade dos portadores de carga em um semicondutor dopado tipo n. Para tanto, utilizamos uma equação semi-clássica baseada na segunda lei de Newton. A aplicação se deu no semicondutor Sulfeto de Zinco (ZnS) nas fases wurtzite (WZ) e zincblende (ZB), dopado tipo n e submetido a campos elétricos de baixa intensidade. A dependência destas propriedades de transporte em função da intensidade do campo elétrico e da temperatura foi analisada. O principal resultado obtido é que a mobilidade na fase WZ é maior que na fase ZB.

Published: November 2019

The present work aimed to characterize the microstructure of the icosahedral phase (quasicrystalline phase-ϕ) of the system with stoichiometric composition of the quasicrystal Al63Cu25Fe12. The ternary alloy with nominal composition of Al63Cu25Fe12 was processed by mechanical alloying (MA) as a viable solid state processing method for producing various metastable and stable quasicrystalline phases. The structural characterization of the obtained samples was performed by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM), while the elemental composition of the chemical elements Al, Fe and Cu were determined by X-ray spectroscopy technique of dispersive energy (EDS). According to the results of XRD, the diffraction patterns of Al63Cu25Fe12 showed the presence of β-Al(Fe, Cu) and λ-Al13Fe4 phases coexist with the thermodynamic ϕ-phase quasicrystalline. Finally, elemental analysis indicates that during alloy synthesis there is little variation of the ideal composition. The results indicate that alloys with high percentage of icosahedral phase can be obtained by casting in the air.

Tofu is a cheese of vegetable origin, derived from soybean, obtained by coagulation of the soybean water-soluble extract (SSE). The use of lemon juice as a coagulant makes it completely organic and can be consumed by people in the vegan food group. The objective of this work was to develop and characterize a tofu cheese, using vegetable coagulant (5-15%) and soy protein concentrate - SPC (0-10%) applying experimental design to maximize the yield of tofu. Also were evaluated the characteristics of acidity, moisture, total solids, proteins, syneresis and ashes in the first and seventh days of storage. In the first day of storage, a high percentage of coagulant resulted in an increase in the acidity of the tofu. High moisture contents were observed in high concentrations of coagulant without soy protein concentrate. In the total solids, the high values were verified in low concentration of coagulant and SPC. Protein, syneresis, and ash were high when added low concentrations of coagulant and SPC. The high yield was observed in the experiment with high SPC and low amount of coagulant. On the seventh day of storage, the high concentration of lemon resulted in a significant effect (p

Published: November 2019

The aim of the present study was to compare the effects of resistance training performed with no external load (NLRT) versus resistance training performed with elastic bands (RTEB) on muscle hypertrophy and functional performance in hospitalized patients. Twenty hospitalized females (age, 59.05±3.2 years; height 163.6±2.5 cm; body mass 70.2±3.6 kgs) were randomly assigned to RTEB or NLRT. Both groups trained three times a week for five weeks. RTEB was performed with elastic bands, while NLRT involved maximum voluntary contractions with no external loads. Biceps brachii, triceps brachii and pectoralis muscle thickness (MT) were measured by ultrasound. Functional performance was measured by the 30s elbow flexion test. MT significantly increased in all muscles tested for both groups, with no differences between groups. Changes ranged from 14 to 38%. Functional performance significantly improved by 42.7% for NLRT and 52.1% for RTEB, with no difference between them. The present results suggest that NLRT might be an efficient, feasible and low-cost strategy to promote morphological and functional benefits in the upper limb of hospitalized patients.

This study investigated the acute effects of inter-set static stretching (ISS) during resistance exercise (RE) on the subsequent neuromuscular and metabolic responses. Twelve resistance-trained men performed three different knee extension RE protocols comprised of seven sets of 10 repetitions in a counterbalanced fashion. The three protocols were: 1) ISS (subjects performed 25 sec of quadriceps stretching between sets during 40 sec rest interval); 2) control (CON, subject passively rested between sets for 40 sec); 3) traditional (TRA, subject passively rested between sets for 120 sec). Total work was lower (p < 0.05) in ISS than CON and TRA (p <0.05). The fatigue index was greater (p < 0.05) in ISS compared with CON and TRA. ISS also resulted in lower (p < 0.05) electromyography (EMG) amplitude during the 6th and 7th sets compared with TRA. Additionally, EMG frequency was lower (p < 0.05) from the 3rd to 5th sets during ISS compared to CON, and from the 3rd to 7th sets compared to TRA. Muscle swelling and blood lactate similarly increased (p > 0.05) in response to all protocols. These results indicate that ISS negatively impacts neuromuscular performance, and does not increase the metabolic stress compared to passive rest intervals.

This study focuses on the risk of pollen allergy due to paper mulberry (Broussonetia papyrifera L.), an Asian invasive plant species now common in large parts of the world. Pollen plays a key role in the pathogenesis of respiratory allergic diseases, particularly rhinitis and asthma, and Islamabad, a major metropolitan city, is severely affected by allergy owing to B. papyrifera pollen. Due to its seasonality and other relationships with climatic variables, we used remote sensing to monitor the trend of pollen count. We also mapped the localisation of patients affected by pollen allergy using geographic information systems. The maximum likelihood algorithm was applied to SPOT-5 satellite imagery for land use/land cover classification. Temporal analysis of remotely sensed data revealed an increasing trend of paper mulberry density towards the southern and south-western part of Islamabad. Although not evident during rainfall, a clear positive correlation was found between patient count and pollen count. Field survey data and hotspot spatial analysis of allergy patients revealed that residents of Shakerperiyan and Lok Virsa areas (Sectors H-8, I-8, I-9, G-8, G-7 and G-6 in Islamabad) had more pronounced symptoms compared to residents of other sectors. The methodology adopted used in this study can be used to map the distribution of similar invasive species in other parts of the country.

Published: November 2019

Mapping the malaria risk at various geographical levels is often undertaken considering climate suitability, infection rate and/or malaria vector distribution, while the ecological factors related to topography and vegetation cover are generally neglected. The present study abides a holistic approach to risk mapping by including topographic, climatic and vegetation components into the framework of malaria risk modelling. This work attempts to delineate the areas of Plasmodium falciparum and Plasmodium vivax malaria transmission risk in India using seven geo-ecological indicators: temperature, relative humidity, rainfall, forest cover, soil, slope, altitude and the normalized difference vegetation index using multi-criteria decision analysis based on geographical information system (GIS). The weight of the risk indicators was assigned by an analytical hierarchical process with the climate suitability (temperature and humidity) data generated using fuzzy logic. Model validation was done through both primary and secondary datasets. The spatio-ecological model was based on GIS to classify the country into five zones characterized by various levels of malaria transmission risk (very high; high; moderate; low; and very low. The study found that about 13% of the country is under very high malaria risk, which includes the malaria- endemic districts of the states of Chhattisgarh, Odisha, Jharkhand, Tripura, Assam, Meghalaya and Manipur. The study also showed that the transmission risk suitability for P. vivax is higher than that for P. falciparum in the Himalayan region. The field study corroborates the identified malaria risk zones and highlights that the low to moderate risk zones are outbreak-prone. It is expected that this information will help the National Vector Borne Disease Control Programme in India to undertake improved surveillance and conduct target based interventions.

Published: November 2019

Chagas continues to be a relevant public health problem in Latin America. In this work, we present a spatiotemporal analysis applied for the evaluation and planning of Chagas vector control strategies. We analysed the spatial distribution of the vector Triatoma infestans infestation related to ongoing control interventions cycles in rural communities near Añatuya, Santiago del Estero, Argentina. A geographical information system was developed for the spatial analysis obtaining, for each house, variables that describe the history of spraying and infestation at each time of interventions. Bi-dimensional histograms were used to describe the spatiotemporal pattern of these activities and peri-domestic infestation at the last intervention was modelled by a neural network model. We qualitatively evaluate control programmes considering the history of infestation and spraying from a spatiotemporal point of view, incorporating new ways of visualising this information. Predictions are based on novel, non-linear models and spatiotemporal indices, which should be useful for strategically allocating Chagas control resources in the future and thus help to better plan spraying strategies.

Most atrial fibrillation (AF) patients need anticoagulation management to reduce the risk of thromboembolic events and stroke. Currently, two major drug therapies are available: warfarin and direct oral anticoagulant (DOAC). This study examined the spatial costs of these therapies and derived the least-cost market areas for both therapies in the study area. The concepts of spatial costs and the principles of forming market areas were used as theoretical starting points, and the patients’ travel, time-loss, and medication cost parameters combined with geographical information systems methods were incorporated into the geospatial model. Results showed that for AF patients who live near the international normalized ratio (INR) monitoring sample collection point and have less than 15 annual INR monitoring visits, warfarin therapy resulted in the lowest cost regardless of patient’s travel mode and their assumed working or retirement status. If the AF patient needs more frequent INR monitoring visits or lives farther from the nearest sample collection point, DOAC would be the least costly option. The modelled results reveal the variety and importance of patients’ cost of time loss and travel costs when a physician selects the appropriate anticoagulation therapy.
