Α New Host Plant for Scobicia cheνrieri (Villa) (Coleoptera: Bostrychidae)
Authors: Buchelos C.TH.
Published: November 2017

Bostrychidae is primarily a family of wood-boring beetles, distributed mainly in the tropics and subtropics. Many species are serious pests of growing trees and felled timber. One species, Rhysopertha dominica (F.), is a grain borer and the most frequently met among beetles infesting stored wheat in Greece (Buchelos 1981). Two other bostrychids, Dinoderus minutia (F.) and Dinoderus brevis Horn, have been recently found in Greece infesting bamboo articles imported from Hong-Kong and the Philippines respectively. Wooden parts (branches of 3 to 18 cm in diameter) of Brachychiton acerifolium Mull. and Brachychiton diversifolium G. Don. (Sterculiaceae) trees, widely used as ornamentals in alleys and parks in Attika, Greece, that have been cut and stored for one at least year in the open, were found heavily infested by bostrychid bee­tles and their larvae; the exterior of these branches was densely perforated by tunnel openings about 1,5 mm in diameter, while the interior presented an almost complete deterioration due to numerous galleries caused by the insects. Due to the fact that the living Brachychiton trees of the region examined were found infestation free, one is lead to the conclusion that the infestation occurred after felling; furthermore, the infestation on B. acerifolium seemed more severe than on B. diversifolium wooden parts. The identification of the adults, based on taxonomic keys of Lesne 1900, Renter 1911, Por to 1929, Portevin 1931 and Fisher 1950, lead to Scobicia chevrieri (Villa) and was confirmed by the identification group of the Bayerische Staatsamlung, Munich. The species belongs to the subfamily Bostrychinae, tribe Xyloperthini, genus Scobicia Lesne; it has also been found under the synonyms: Apate chevrieri Villa, Apate capilata Dejean, Xylopertha chevrieri J. Duval, Xylopertha foveicollis Allard, Xylopertha pustulate Kiesenwetter and Scobicia pustulate Jacobson. The adults found in the region of Attika, near Athens, are 3.3-4.5 mm long and 1.2 to 1.5 wide. S. chevrieri is reported being distributed in many regions of Italy from the Alpes and Tyrol to Sardinia and Sicily, across the French Mediterranean coast and Corsica, Spain (Malaga, Seville, Cordoba), Morocco, Tunisia, Algeria, Israel, Libanon, Syria, Caucasus, Crimea and Cyprus. In the relevant literature, S. chevrieri is recorded attacking mainly dead branches of the following plants: fig (Ficus sp.), mulberry (Maras sp.), green oak (Quercus ilex L.), English oak (Quercus robur L.), evergreen oak (Quercus coccifera L.), laurel (Laurus nobilis L.), mastic-tree (Pistacia lentiscus L.), birch (Betula sp.), fox grape (Nibs lahrusca L.), pomegranate (Punica granatani), chestnut (Castanea sp.) and gem-tree (Eucalyptus spp.). Brachychiton spp. is recorded here for the first time as host of the insect.

Distribution of Population of Immature Stages of Pear Psylla, Cαcopsyllα pyri, within the Tree and Development of Sampling Strategy
Authors: Stratopoulou E. T. , Capatos E.T.
Published: November 2017

The distribution of Cacopsylla pyri (L.) (Homoptera-Psyllidae) infestation within the tree canopy and in the varions organs of the tree was investigated in the region of Magnesia (Greece) during 1988 and 1989. The upper parts of the tree canopy and the sections ori­entated to South and west were infested heavier during winter and spring. Later in the scason the infestation was diffused within the tree canopy and at the end of the season a rather uniform pattern of distribution was observed. During the first oviposition period (February-March), the preferred oviposition sites were flower buds white during spring (second generation) they were the leaves of flower buds and young shoots. Sampling strategy for the study of populations of immature stages of pear psylla is discussed on the oasis of these findings.
Phenology of Population of Immature Stages of Pear Psylla, Cαcopsyllα pyri, in the Region of Magnesia (Greece)
Authors: Stratopoulou E. T. , Capatos E.T.
Published: November 2017

The phenology of the population of immature stages of pear psylla, Cacopsylla pyri (L.), was studied in Greece (region of Magnesia), during the period 1988-1991 and it was found to follow a basic pattern. Pear psylla produces 5-6 gencrations per year. The first generation develops during the period February-middle April and it is quite discrets. Three overlapping generations are developed during the period front middle April until middle August but the amount of overlapping varies front year to year. Front middle August until the end of the season pear psylla produces 1-2 generations, i.e. only a part of the firth generation complotes the sixth one. Population density is generally low during the first generation but during May-June reaches verty high levels. During sommer, strong environmental pressure, supresses the population of pear psylla to low levels but it recovers again during September-October.
Control of Synanthedon (Aegeria) myopaeformis by Mating Disruption Using Sex Pheromone Dispensers in Northern Greece
Authors: Kyparissoudas D.S. , Tsourgianni Α.
Published: November 2017

In 3 successive years (1990-1992) polyethylene tube dispensers, each containing 50.5 mg synthetic sex pheromone of the apple clearwing moth, Synanthedon (Aegeria) myopaeformis Borkh., were placed at a density of 680 per ha, once a year, in two adjacent commercial apple orchards each I ha in size. The degree of confusion reached almost 100% by releasing about 6 mg/ha/h, whereas the number of mated females decreased by 72.86%, compared with the untreated orchard. In 1993, after 3 years of experiments, a reduction of up to 91% of empty pupal skins per tree was attained. The encouraging results, especially when taking into account the relatively small size of the orchards, opens opportunities for the integrated control of this apple insect pest under the conditions of Northern Greece.

Comparative Field Studies of Various Traps and Attractants for the Olive Fruit fly, Bαctrocerα oleαe
Authors: Haniotakis G.E. , Broumas ΤΗ. , Liaropoulos C.
Published: November 2017

In the framework of an ongoing effort for development of an effective trap for the control of the olive fruit fly, Bactrocera oleae (Gmelin) (Diptera, Tephrifidae), by mass trapping, four trap types (wood, cloth, laminate, McPhail), seven different colors of laminate traps, different food attractants, attractant combinations or formulations (total of ten cases), and two insecticides (deltamethrin, b-cyfluthrin) used as killing agents on the traps, were compared under field conditions. The following conclusions may be drawn: Laminate traps (paper envelopes with a polyethylene lining inside, 15×20 cm in size, containing 70 g of ammonium bicarbonate salt and impregnated with 15 mg (a.i.) of an insecticide), were more effective than wood traps. Effectiveness of laminate traps can be enhanced by using an attracting color or in the case of the food attractant ammonium bicarbonate, by incorporating copper oxychloride. Combinations of two protein hydrolysates were more effective than one hydrolysate alone. Effectiveness of protein hydrolysates is not constantly higher than that of ammonium bicarbonate, the use of which is more economic and convenient. The insecticide b-cyfluthrin may be used on traps instead of deltamethrin, which is known to have a repellent effect on the olive fly, especially Linder high concentrations, and is unstable under natural UV light.
The Effects of Νatural Enemies on Aphid Populations on Processing Tomato in Central Greece
Authors: Lykouressis Ρ. , Perdikis D. CH. , Chalkia CH. Α.
Published: November 2017

Two species of aphids, Macrosiphion euphorbiae (Thomas) and Myzus persicae cae (Sulzer) (Homoptera: Aphididae) were the only ones which developed populations on processing tomato in a two year study conducted in central Greece. The aphid population structure showed that M. euphorbiae was much more abundant than M. persicae in both years. The former species peaked in August whilst the latter did not show any particular peak over the two successive years. Some species of natural enemies were recorded. Orius niger Wolff was found in low numbers scattered over a long period but mainly towards the end of the growing season, and it did not correlate with the aphid population. The rate of parasitism of M. euphorbiae by Aphelinus abdominalis Dalman and Praon volucre (Haliday) was very low and it seemed that these two parasitoid species did not have any particular effect on the aphid population suppression. Macrolophus pygmaeus Rambur was the key natural enemy and the most abundant and effective among the predators found. Its highest numbers occurred towards the end of the growing season following the aphid population peak, suggesting a numerical response of this species to its prey. A proportion of the population of M. pygmaeus occurring on tomato plants after fruit harvesting, might he collected and subsequently released in crops such as tomato, pepper and eggplant to biologically control pests in greenhouses, like aphids and whiteflies, thus contributing to the production of healthy vegetable products.
Seasonal development and ovipositing behavior of Marchalina hellenica (Hemiptera: Margarodidae)
Authors: Gounari Sofia
Published: November 2017

Marchalina hellenica, Gennadius (Hemiptera: Margarodidae) is the main honeydew producing insect of pine trees ίη Greece. Its behavior during oviposition, the reproductive capacity, oviposition period, pre-hatching period, and life span of the οviposited female and other aspects of its reproductive behavior in the field and in the laboratory, have been recorded in a three-year research. Μ. hellenica completes one generation per year. It is mainly parthenogenetic. The adult female appears on the trees, looking for an oviposition site from late March to late April. Its oviposition period in the field lasts about 20 days, while the hatching period lasts about 30 days. Live females can be found on the trees until the end of May, so there is a coexistence of three stages of Μ. hellenica, adult, eggs and 151 stage nymphs, in the field for about one month. Μ. hellenica is able to oviposit in the laboratory in room conditions. Its ovipositing period is as long as 16 days, while the total number of eggs laid is on average 262. Body weight was significantly correlated with the total number of eggs laid.
Comparative field studies of various traps and attractants for the Mediterranean fruit fly Ceratitis capitata (Diptera: Tephritidae) in fall
Authors: Liaropoulos K. , Zervas G. , Mavraganis V. , Broumas T. , Tsiropoulos G. , Tsirogiannis V.
Published: November 2017

To clarify questions regarding the effectiveness of the many different types of traps and semiochemicals used for the monitoring and the control of the Mediterranean Fruit Fly, Ceratitis capitata (Wiedemann) (Diptera: Τephrititae), seven trap types, four food attractants, one sex attractant and a combination of food and sex attractant, were evaluated under field conditions in orange orchards in fall. No major differences were observed between trap designs resembling the original McPhail glass trap. The plastic bottle trap of 1,5L volume, with four side openings for one-way fly entrance, proved very efficient when filled with a proteinaceous food attractant Ζ1. From the attractants, two of them, Ζ1 and Entomela showed the best performance. The combination of food and a sex attractant showed no significant synergistic effects on trap efficiency. The findings allow a better choice among trap types and attractants, available today in the market, for Medfly monitoring and control.

Published: November 2017

In August 2016, severe infestations of sesame crops by the sesame leaf webber and capsule borer, Antigastra catalaunalis (Duponchel) (Lepidoptera: Crambidae), were recorded in rural areas of the Regional Unit of Drama, Northern Greece. Larval feeding-damage symptoms were observed on leaves and capsules. Infestations were recorded in all of the inspected sesame fields. The infestation levels were considerable high resulting in significant economic loss. To our knowledge, this is the first report of A. catalaunalis severe infestation on sesame in Greece.
Experimental autoimmune encephalomyelitis from a tissue energy perspective
Authors: Desai Roshni A , Smith Kenneth J
Published: November 2017

Increasing evidence suggests a key role for tissue energy failure in the pathophysiology of multiple sclerosis (MS). Studies in experimental autoimmune encephalomyelitis (EAE), a commonly used model of MS, have been instrumental in illuminating the mechanisms that may be involved in compromising energy production. In this article, we review recent advances in EAE research focussing on factors that conspire to impair tissue energy metabolism, such as tissue hypoxia, mitochondrial dysfunction, production of reactive oxygen/nitrogen species, and sodium dysregulation, which are directly affected by energy insufficiency, and promote cellular damage. A greater understanding of how inflammation affects tissue energy balance may lead to novel and effective therapeutic strategies that ultimately will benefit not only people affected by MS but also people affected by the wide range of other neurological disorders in which neuroinflammation plays an important role.
NastyBugs: A simple method for extracting antimicrobial resistance information from metagenomes

Published: November 2017

Multidrug resistant bacteria are becoming a major threat to global public health. While there are many possible causes for this, there have so far been few adequate solutions to this problem. One of the major causes is a lack of clinical tools for efficient selection of an antibiotic in a reliable way. NastyBugs is a new program that can identify what type of antimicrobial resistance is most likely present in a metagenomic sample, which will allow for both smarter drug selection by clinicians and faster research in an academic environment.
Prehire Screening and Subjective Performance Evaluations
Authors: Chen Bin R. , Li Sanxi
Published: November 2017

We study a two-stage model in which the agent’s ability is initially unknown to any party, but the principal can choose a prehire screening scheme to discover the agent’s ability before offering a contract. Perfect screening enables the principal to fine-tune the contract to the agent’s ability, but it also prevents her from enforcing a contract that is contingent on subjective interim performance measures. Given that interim performance measures are critical for motivating first-stage effort, the principal may benefit from adopting no screening or partial screening. When partial screening is employed, the halo effect—a commonly observed bias in subjective evaluation practices—emerges in the equilibrium.

Incentives and Ratcheting in a Multiproduct Firm: A Field Experiment
Authors: Brahm Francisco , Poblete Joaquin
Published: November 2017

We develop a model and derive behavioral predictions for a multiproduct sales force subject to goals set based on past performance. We test these predictions using a field experiment in which 53 salespersons from a Chilean beverage company face exogenous variations in monthly sales goals. Confirming our predictions, we found that (1) absent strategic considerations—no goal ratcheting—salespersons increase (decrease) sales in the product category for which the return to effort increases (decreases), (2) including strategic considerations behavior reverses: salespersons who expect high goal ratcheting decrease (increase) sales in the category for which the return to effort increases (decreases), (3) sales did not change for the average salespersons, reflecting heterogeneity in the expectations of goal ratcheting rather than unresponsiveness to incentives. Our study points at the importance of the dynamics of incentive design, in particular, the importance of understanding the dynamics of goal setting in firms.

Published: November 2017

A busca por estratégias gerenciais que permitam que a organização alcance melhores resultados tem atraído estudiosos da área e gestores interessados nos resultados de suas pesquisas. Tal interesse é decorrente, dentre outros aspectos, da concorrência acirrada e de volatilidades do ambiente. A pesquisa objetiva modelar as ações ambidestras e suas dimensões: exploração e explotação, em contraste com desempenho das farmácias de uma rede do Rio Grande do Sul. A pesquisa foi baseada na pesquisa quantitativa e descritiva, utilizando o método survey, baseado em questionários fechados aplicados às 612 farmácias, com uma taxa de retorno de 6,53%, pertencentes à rede FARXV. A análise fatorial confirmatória e a modelagem de equações estruturais foram utilizadas para tratar os dados coletados. Foi concluído que o investimento em estratégias ambidestras, pelos gestores das empresas, resulta em desempenho correspondente. Embora os resultados da associação sejam igualmente positivos, não foi confirmado que as estratégias de exploração e explotação reflitam desempenho.
Exploring Phonological Awareness Skills in Children With Intellectual Disability
Authors: Sermier Dessemontet Rachel , de Chambrier Anne-Françoise , Martinet Catherine , Moser Urs , Bayer Nicole
Published: November 2017

The phonological awareness skills of 7- to 8-year-old children with intellectual disability (ID) were compared to those of 4- to 5-year-old typically developing children who were matched for early reading skills, vocabulary, and gender. Globally, children with ID displayed a marked weakness in phonological awareness. Syllable blending, syllable segmentation, and first phoneme detection appeared to be preserved. In contrast, children with ID showed a marked weakness in rhyme detection and a slight weakness in phoneme blending. Two school years later, these deficits no longer remained. Marked weaknesses appeared in phoneme segmentation and first/last phoneme detection. The findings suggest that children with ID display an atypical pattern in phonological awareness that changes with age. The implications for practice and research are discussed.

Data from 949 children and adolescents with intellectual disability ages 5 to 16 for whom the Supports Intensity Scale–Children's Version–Catalan Translation was completed was used, in combination with data from the U.S. standardization sample, to examine measurement invariance and latent differences in the Catalonian sample. Results suggest that the same set of items can be used to measure support needs across U.S. and Catalonia samples and that there are age-related differences in support needs in the Catalonia sample, particularly between children ages 5 to 10 and 11 to 16 years of age. This differs from findings with the U.S. sample, where differences were found in a greater number of age cohorts. Implications for future research and practice are discussed.
Preservation of Functional Microvascular Bed Is Vital for Long-Term Survival of Cardiac Myocytes Within Large Transmural Post-Myocardial Infarction Scar
Authors: Nofi Colleen , Bogatyryov Yevgen , Dedkov Eduard I.
Published: November 2017

This study was aimed to understand the mechanism of persistent cardiac myocyte (CM) survival in myocardial infarction (MI) scars. A transmural MI was induced in 12-month-old Sprague–Dawley rats by permanent coronary artery ligation. The hearts were collected 3 days, 1, 2, 4, 8, and 12 weeks after MI and evaluated with histology, immunohistochemistry, and quantitative morphometry. Vasculature patency was assessed in 4-, 8-, and 12-week-old scars by infusion of 15-micron microspheres into the left ventricle before euthanasia. The infarcted/scarred area has a small continually retained population of surviving CMs in subendocardial and subepicardial regions. Surprisingly, whereas the transverse area of subepicardial CMs remained relatively preserved or even enlarged over 12 post-MI weeks, subendocardial CMs underwent progressive atrophy. Nevertheless, the fractional volume of viable CMs remained comparable in mature scars 4, 8, and 12 weeks after MI (3.6 ± 0.4%, 3.4 ± 0.5%, and 2.5 ± 0.3%, respectively). Despite the opposite dynamics of changes in size, CMs of both regions displayed sarcomeres and gap junctions. Most importantly, surviving CMs were always accompanied by patent microvessels linked to a venous network composed of Thebesian veins, intramural sinusoids, and subepicardial veins. Our findings reveal that long-term survival of CMs in transmural post-MI scars is sustained by a local microcirculatory bed.
Wearables for Promoting Physical Activity
Authors: Strath Scott J , Rowley Taylor W
Published: November 2017

BACKGROUND

The rapid expansion and popularity of consumer-wearable physical activity monitors (WPAMs) has enabled the integration of technology into physical activity (PA) intervention, deployment, and evaluation. This brief review reports on the accuracy of consumer-WPAMs, considers the intervention effects of using consumer-WPAMs, and offers future considerations as the proliferation of this area of product development and consumer use continues to escalate.

CONTENT

The studies reviewed document the utility for consumer-WPAMs to objectively assess PA, with output metrics similar to research-grade activity monitors. Early intervention efficacy for the use of consumer-WPAMs to increase PA holds considerable promise. Substantial increases in moderate- to vigorous-intensity PA (MVPA) have been reported across different research study designs and populations in which consumer-WPAMs have been used in isolation or in conjunction with other behavioral change strategies. The utility of consumer-WPAMs is currently being investigated in clinical populations, notably showing increases in PA in individuals at risk for cancer or post cancer survivors, in those with chronic obstructive pulmonary disease, and in postsurgical patients. There has been a proliferation of registered trials at clinicaltrials.gov, and an increase of disseminated works regarding the use of consumer-WPAMs is expected.

There are many research studies documenting the validity and intervention effectiveness of consumer-WPAMs; evidence is emerging on the health benefits linked to use of such devices. Future work on the long-term effects of consumer-WPAMs on behavior and health is warranted, and prospects appear exciting as wearable technology advances and adoption increases.
A epipolesis – receção de um discurso de origem homérica pela historiografia portuguesa de Quinhentos
Authors: Henriques Luís
Published: November 2017

Este artigo aborda, de forma breve, a receção de um tipo de discurso que remonta à épica homérica pela historiografia portuguesa do século XVI: a epipolesis. Numa época de emulação, os historiógrafos quinhentistas fizeram das suas obras não só repositórios da memória passada, mas também composições elevadas e eruditas em que a retórica desempenhou um papel determinante. Tal como na Antiguidade, assiste-se à progressiva dramatização das obras historiográficas, com a inserção de impressivas descrições de batalhas e de discursos, como a epipolesis. Na circunstância, este tipo de discurso imprime enargeia às ekphraseis em que se enquadram, já que um capitão, proferindo um discurso exortativo enquanto avança pelas alas do seu exército, contribui não só para a consagração do seu estatuto de ótimo general, como provoca comoção nos leitores destas narrativas. Assim, do ponto de vista metodológico, um corpus de discursos identificado na historiografia portuguesa quinhentista é analisado tipológica e diferenciadamente de acordo com fatores como a superfície terrestre ou marítima em que os ditos discursos são pronunciados. Em seguida, o mesmo corpus será analisado de acordo com os princípios metodológicos aplicados por Longo (1983) aos discursos de Tucídides que, atendendo à sua pronunciação, podem ser unitários ou diferenciados dependendo da homogeneidade ou heterogeneidade qualitativa do auditório.
Ensino da língua na perspectiva discursiva: um exercício de leitura
Authors: Coelho Victoria Wilson da Costa
Published: November 2017

O trabalho concentra-se nos modos de conceber o ensino da língua portuguesa sob a perspectiva discursiva de raiz bakhtiniana, considerando, especialmente, os sentidos da “compreensão ativa e responsiva” da linguagem e do discurso. À luz do modelo ideológico de letramento e de alguns subsídios da pragmática, a sala de aula é entendida como espaço (de tensão) de construção de linguagens e conhecimentos oriundos de esferas distintas que ali se integram a partir de e com base em experiências sociais e subjetivas tanto de professores quanto de alunos. Objetiva-se elaborar uma aula em que os alunos sejam convidados a refletir e compreender que as palavras estão prenhes de um “conteúdo ideológico e vivencial”, pois “não são palavras o que pronunciamos ou escutamos”, mas atos de fala, ações com e sobre a linguagem. Articular o campo do letramento à teoria enunciativa bakhtiniana e ainda ao campo da pragmática é uma forma de entender como os aspectos sociais, extralinguísticos constituem, integram a língua e o discurso e os tornam vivos, ao mesmo tempo em que constituem os sujeitos em situações reais de interação, nas várias esferas sociais da vida. Integram-se a esse trabalho pedagogias que questionam a “visão bancária” do ensino e os saberes dominantes em relação aos outros saberes, a fim de, por meio do ensino da língua e da gramática, desestabilizar e desnaturalizar significados e sentidos regularizados e sacralizados.
O ensino de português com base no gênero textual e no caráter interativo e social da língua
Authors: Wittke Cleide Inês
Published: November 2017

Nas últimas décadas, principalmente depois da publicação dos PCNs (1998, 1999), muito se tem pesquisado e refletido sobre os insatisfatórios resultados obtidos a partir do trabalho com a língua no ensino básico, tanto no que diz respeito a práticas de leitura, quanto de produção oral e escrita (MARCUSCHI, 2008, 2010; KOCH; ELIAS, 2010, 2016). Nesse quadro, o presente estudo tem como objetivo problematizar o ensino de língua, na busca de apresentar possibilidades que possam resgatar sua importância e produtividade social (BRONCKART, 2012), na medida em que o texto/gênro textual é assumido como objeto de ensino e de análise (SCHNEUWLY; DOLZ, 2009, 2010), uma vez que definimos a língua como uma prática constante de interação verbal. Com base nos estudos bakhtinianos dos gêneros, vemos o ensino de língua como processo interativo e dialógico (BAKHTIN, 1992), cuja meta é criar possibilidades pelas quais o aluno possa desenvolver sua capacidade de pensar, ora por meio de práticas de leitura e de escuta, ora via atividades de fala e de escrita para um interlocutor real ou imaginário (MENDONÇA, 2012).
Gamifying a Course to Teach Games and Simulations for Learning
Authors: Stansberry Susan L. , Haselwood Scott M.
Published: November 2017

This design case includes the challenges, considerations, and decisions associated with the design, development, and delivery of a master’s level educational technology course on teaching and learning with games and simulations. A master’s level course, Digital Games and Simulations in the Classroom, faced redesign in order to add a gamification component to be modeled through 3D GameLab and Shivtr. The design decisions made and resulting issues are detailed in this paper. This paper aims to reveal benefits in two key areas: (a) helping a population of primarily non-gamer educational technology graduate students see games and simulations as viable resources for improving learning and (b) modeling gamification as a means to help instructors use gamification as their own instructional strategy
Seeing the Unseen—Spatial Visualization of the Solar System with Physical Prototypes and Augmented Reality
Authors: Majgaard Gunver , Larsen Lasse Juel , Lyk Patricia , Lyk Morten
Published: November 2017

The presented design case gives examples of designing an Augmented Reality learning scenario about the Solar System with 6th grade. The case connects the physical and virtual worlds in Augmented Reality, like 3D planetary globes floating above the textbook. This way, students can interact with digital information embedded in the physical environment.The stakeholders in the design process consisted of researchers in the role of designers, while teacher and students were co-designers and informants. During the process, several physical and digital prototypes were developed and tested.Through the co-design development process, it became clear that the design affordances of Augmented Reality together with the scholastic content of the Solar System invited design potentials such as visualising far away objects by bringing them near i.e. being able to see what is otherwise difficult to perceive. Through the development process, the design potentials of Augmented Reality acted as a lens to access distant realities; included herein visualisation of planet sizes, their relationships, and movement pattern
Designing Authentic and Engaging Personas for Open Education Resources Designers

Published: November 2017

To guide designers developing open education resources for adults preparing for a high school equivalency exam, we developed six authentic personas that represented adults without high school diplomas. Our goal was to assist open education resources designers to develop empathy toward their learners and place themselves in their learners’ shoes. The purpose of this design case is to share our journey in designing, constructing, and integrating authentic personas for the open education resources designers.
Aesthetic perception, attention, and non-genericity: How artists exploit the automatisms of perception to construct meaning in vision
Authors: Bundgaard Peer F. , Heath Jacob , Østergaard Svend
Published: November 2017

The present work is an attempt to bring meaning to the fore of not only empirical aesthetics but also experimental aesthetics. We have addressed meaning in terms of attention-grabbing perceptual structure, doing so in the strong sense of structure; i.e., structure understood as a pure spatial relation between shapes, independently of what objects these shapes represent. The structures we investigate are the so-called non-generic configurations that obtain between objects seen from a unique vantage point. In the paper, we first introduce the notion of non-genericity, in general, and its use in visual art in particular, where it is claimed to affect the visual brain as an attention grabber. We then present an experiment we have designed to test the effect of such a relation on the visual brain, and we give evidence to the effect that non-generic configurations in pictures do attract attention significantly more than their generic counterparts. Non-genericity can therefore be considered as one among other pictorial techniques artists dispose of to construct perceptual meaning in vision.
Towards integrating phenomenology and neurocognition: Possible neurocognitive correlates of basic self-disturbance in schizophrenia
Authors: Nelson Barnaby , Sass Louis A.
Published: November 2017

Phenomenological research indicates that disturbance of the basic sense of self may be a core phenotypic marker of schizophrenia spectrum disorders. Basic self-disturbance refers to disruption of the sense of ownership of experience and agency of action and is associated with a variety of anomalous subjective experiences. Little is known about the neurocognitive correlates of basic self-disturbance. In this paper, we review recent phenomenological and neurocognitive research and point to a convergence of these approaches around the concept of self-disturbance. Specifically, we propose that subjective anomalies associated with basic self-disturbance may be associated with: 1. source monitoring deficits, which may contribute particularly to disturbances of “ownership” and “mineness” (the phenomenological notion ofpresence) and 2. aberrant salience, and associated disturbances of memory, prediction, and attention processes, which may contribute to hyper-reflexivity, disturbed “grip” or “hold” on the perceptual and conceptual field, and disturbances of intuitive social understanding (“common sense”). These two streams of research are reviewed in turn before considering ways forward in integrative models, particularly regarding the role of early neurodevelopmental disturbances, primary versus secondary disturbances, and the state versus trait nature of such pathology. Empirical studies are required in a variety of populations in order to test the proposed associations between phenomenological and neurocognitive aspects of self-disturbance in schizophrenia. An integration of findings across the phenomenological and neurocognitive domains would represent a significant advance in the understanding of schizophrenia and possibly enhance early identification and intervention strategies.

The monogenean, Afrogyrodactylus ardae sp. n., is described from the African tetra, Rhadbalestes septentrionalis (Characiformes: Alestidae), collected from the Niokolo Koba and Gambie Rivers in the Niokolo-Koba National Park, Senegal during 2008. The newly described species can be differentiated from three known species of the genus based on the dimensions of its opisthaptoral hard parts, having the smallest ones, and based on the shape of the marginal hooks sickle. The present finding represents a new host record for the genus Afrogyrodactylus.

Published: November 2017

Aim:

The purpose of this review is to systematically review all the reported cases and case series of caesarean scar pregnancy (CSP) managed expectantly without any intervention in order to understand the outcomes of pregnancy which will guide clinicians and patients in making treatment choices.

Methods:

An electronic search on PubMed, EMBASE and Cochrane databases and a manual search from references of the articles were performed. Studies were selected based on inclusion and exclusion criteria. Data were extracted for various outcomes of pregnancy and the quality of the reports was assessed using a modified Delphi technique.

Results:

A total of 56 cases of CSP from 11 reports were included in the review, including 44 cases with foetal cardiac activity. Live births were achieved in 73% of cases with a quarter of them born before 34 weeks. Hysterectomy rates were 70%. In 12/44 (27%) of cases pregnancies were lost due to complications before 24 weeks. Most (67%) of the CSPs with no foetal cardiac activities resolved on expectant management and the remaining required intervention for bleeding.

Conclusions:

Caution should be exercised when choosing expectant management in cases of viable CSPs, and if chosen, the patient should be counselled adequately for possible outcomes including loss of pregnancy and hysterectomy. Expectant management is acceptable in CSPs with no foetal cardiac activity. There is a need for prospective research on this topic with adequate reporting on possible prognostic markers, as well as a need to improve on the techniques to prevent loss of fertility during delivery.
Quantitative analysis by flow cytometry of green fluorescent protein-tagged human phenylalanine hydroxylase expressed in Dictyostelium
Authors: Kim Hye-Lim , Ryu Hyun-Chul , Park Young Shik
Published: November 2017

We have developed a fluorescence assay system to monitor the protein levels of human phenylalanine hydroxylase (hPAH). Wild-type (WT) and three mutant hPAHs (I65T, L255V, and S349L) were expressed as green fluorescent protein (GFP)-tagged forms in a PAH knockout mutant (pah
−) of Dictyostelium discoideum Ax2. The fluorescence-activated cell sorting (FACS) analysis showed that the GFP positive cells were the most frequent in WT but were rare in pah
−, demonstrating the successful expression of GFP-tagged hPAHs in Dictyostelium. The fluorescence levels of mutants relative to WT were higher than expected from the protein amounts determined from the non-tagged forms, probably due to the presence of the N-terminal GFP. However, treatment of the cells with cumene hydroperoxide, which is known to accelerate protein degradation, decreased fluorescence levels, suggesting that protein stability changes in individual mutations can be monitored by FACS analysis. For an evaluation study, a putative pharmacological chaperone effect of yeast extract on S349L was examined by Western blot and FACS analysis. Both the protein amount and the fluorescence levels were increased by yeast extract, supporting that the FACS analysis could replace the time- and labor-consuming procedures such as the Western blot and cell culture. The fluorescence-based cell assay system may be valuable for the high-throughput screening of pharmacological chaperones for phenylketonuria mutations.
The argumentative and rhetorical function of multimodal metonymy
Authors: Rocci Andrea , Mazzali-Lurati Sabrina , Pollaroli Chiara
Published: November 2017

The aim of this article is to contribute to the theoretical development of multimodal metonymy and the argumentative and rhetorical role that the trope can fulfil in multimodal advertising campaigns. A model for the analysis of multimodal tropes in page-based advertising messages is developed by drawing insights from different disciplines. This model involves the identification of the elementary and layout components of the message, the description of its multimodal structure (in terms of the visual structure and the contribution of the verbal component), the reconstruction of its meaning operation, and the reconstruction of its enthymematic structure. In particular, the meaning operation is reconstructed by the employment of Conceptual Integration Theory, which we have slightly revised in order to better account for metonymical mappings. The enthymematic structure is reconstructed following the Argumentum Model of Topics, a model of argument schemes that enables one to make explicit the contextual and the logical dimensions of arguments. Based on the tenets of the two frameworks, we claim that multimodal metonymy condenses and gives access to a complex chain of connections, which mirrors the argumentation the audience is invited to infer. This argumentation is based on causal schemes of reasoning. This claim results in the in-depth analysis of both a billboard belonging to an anti-AIDS campaign and a social campaign by Greenpeace against the use of environmental-damaging paper for toy packages by Mattel.
Hjelmslev, la sémiotique et l’École de Paris
Authors: Zinna Alessandro
Published: November 2017

An initial appraisal of the contribution of Hjelmslevian theory to the structuring of French semiotics was made during an interview with A-J. Greimas in 1986. Thirty years later, this article draws a more complete picture of Louis Hjelmslev’s contribution to the semiotics of the School of Paris. Starting with a lexical mapping of Hjelmslev’s legacy, we focus on the definition of semiotics. According to the Prolégomènes of Hjelmslev, the first volume of the Dictionary of Greimas and Courtés gives the definition of semiotics as a “hierarchy of relationships.” A historical investigation reveals, however, a lack of certainty about which exact place should be given to participative oppositions. Considering both the early writings of the Danish author as well as the developments in tensive theory, an alternative definition seems essential. In the hierarchy of relationships (particular and qualitative), this definition incorporates other modes of meaning, specifically the participative network of relationships. According to Hjelmslev’s categorization of cases, such integration reconciles logical and pre-logical orientations. Ultimately, this definition is the closest to the logic of hypertexual writing, to language and being.

Garcinia mangostana L. (the queen of fruits, mangosteen, family Guttiferae) is a wealthy source of xanthones. The CHCl3 soluble fraction of the air-dried pericarps of G. mangostana provided a new xanthone: mangostanaxanthone VII (5), along with four known xanthones: mangostanaxanthones I (1) and II (2), gartanin (3) and γ-mangostin (4). The structural verification of these metabolites was achieved by different spectral techniques, including UV, IR, 1D and 2D NMR and HRESIMS. The new metabolite was assessed for cytotoxic potential, using sulforhodamine B (SRB) assay towards the A549 and MCF-7 cancer cell lines. Moreover, its antimicrobial effects were evaluated against various bacterial and fungal strains, using agar disc diffusion assay. Mangostanaxanthone VII showed moderate cytotoxic activity against the A549 and MCF7 cell lines with IC50s 26.1 and 34.8 μM, respectively, compared with doxorubicin (0.74 and 0.41 μM, respectively).
A Comparative Evaluation Between CABAC and CAVLC

Lossless video coding improves the coding efficiency of the standard H.264/AVC. In this work, we adjusted the standard H.264/AVC to make it conservative. We removed the quantification process of the standard H.264/AVC coding chain because this block is the first responsible for the degradation of the reconstructed video. In the framework of the lossless compression, we compared two entropy codings: CABAC (context-based adaptive binary arithmetic coding) and CAVLC (context-based adaptive variable length coding). The simulation results showed that CABAC reduces the total bit of the coded sequence, but increased the execution time compared to CAVLC. Thanks to the lossless video coding, the gain performance reached from 15 to 19 %.
Prediction of Quantitative Response of Under-Reamed Anchor Piles in Soft Clay Using Laboratory Model Study

Published: November 2017

The foundation of many civil engineering structures is required to be designed as an anchor foundation subjected to upward load action. The shallow as well as deep anchor in soft clay is an important but complex soil-foundation system that must be analyzed theoretically. As direct determination of the quantitative response by the field test is a very difficult and expensive exercise, the physical modelling technique is considered as an easy alternative for prediction of (i) ultimate pulling capacity and (ii) pull-rise curve. This paper highlighted the potential use of two parameters viz. (i) factor of geometrical relationship (K) and (ii) cohesion factor (N), obtained by conducting laboratory tests on two models of different scale factors for the intended purpose. The K and N parameters were constant for both the prototype foundation and small size model tested in laboratory. The under-reamed concrete pile in soft clay was considered as a soil-foundation system and shallow as well as deep under-reamed anchor piles were investigated in this study. Besides, straight shafted concrete piles were also considered in both categories of shallow and deep anchors. It was found that the physical modelling technique using two characteristic system parameters and by incorporating the model scale factor effect enables the prediction of the earlier stated quantitative response of prototype under-reamed anchor pile foundation in soft clay with a reasonable degree of accuracy. A methodology involving curve fitting procedure was also developed to predict the “pull-rise” curve for a prototype soil-foundation system under consideration.
Micromechanical Simulation of Influence Factors of Indirect Tensile Test of Asphalt Mixture

Published: November 2017

A heterogeneous asphalt mixture is regarded as a multiphase material comprised of coarse aggregates, air voids, and asphalt mastic; namely fine aggregates, fines, and asphalt binder in this study. An indirect tensile test (IDT) model of asphalt mixture with a given gradation was developed. The parallel-bond model (PBM), whose sets of microparameters are obtained by comparing laboratory measures with numerical simulation results, was used to characterize internal contact behavior of asphalt mixture. After that, digital samples were employed to implement a series of numerical tests to investigate the influence factors, such as coarse aggregate size, sample scale, air voids content, and loading rate on the IDT microstructure and macroscopic mechanical behaviors of asphalt mixture, qualitatively or quantitatively. The results indicated that the coarse aggregate size has a significant effect on material IDT behaviors, and the 4.75–9.5 mm aggregate particles are critical to forming the skeleton structure. Increasing sample scale, air voids and loading have a negative impact on asphalt mixture fracture behaviors, especially on the tensile strength. Moreover, increasing scale revealed that the presented IDT model can be used to simulate crack growth, and the DEM provides an auxiliary tool to further study anti-cracking behaviors of asphalt mixture.
