Group norm violations in an online environmental social network: Effects on impression formation and intergroup judgments
Authors: Song Hwanseok , Schuldt Jonathon P. , McLeod Poppy L. , Crain Rhiannon L. , Dickinson Janis L.
Published: November 2017

Much research has demonstrated the power of social norms to affect proenvironmental behavior and conservation-related attitudes and beliefs in traditional “offline” social contexts. With the emergence of social media and citizen science platforms that allow for socially coordinated conservation efforts at scale comes a need to better understand the influence of social norms in online contexts. The present experiment explored effects of norm violations on impression formation and intergroup judgments within the context of Habitat Network, a socially networked mapping application where users create and share virtual representations (maps) of their properties. Results revealed that when participants viewed a map depicting the violation of a strongly held group norm—namely, the presence of an outdoor (vs. indoor) pet cat—they judged the map owner as significantly less likely to engage in a variety of proenvironmental behaviors. Importantly, this effect emerged despite evidence that the owner was already engaging in various sustainable practices. Moreover, the effect was mediated by the perceived quality of wildlife habitat represented by the map and moderated by participants’ group membership status (as a cat owner) in a manner consistent with theories of impression formation and intergroup judgments. We discuss implications for social cognition and intergroup relations in proenvironmental online contexts.
Black texts on white paper: Learning to see resistant texts as an approach towards decolonising planning
Authors: Winkler Tanja
Published: November 2017

I recently attended an international conference on planning in Africa. Here, it was suggested that the colonial era was over and that planners are already well-versed in decolonising theories and practices. Such suggestions came from Northern and Southern scholars alike. By means of this article, I hope to disrupt this privileged position by introducing the idea of resistant texts which are most often found in endogenous systems of knowledge production. I then explain how decoloniality – which calls for an epistemic de-linking from Western knowledges – might assists planners in seeing resistant texts before attempting to arrive at anti-colonial interventions.
Anticipatory discourse in prenatal education
Authors: Hanell Linnea
Published: November 2017

This article explores communicative aspects of preparing others, by studying prenatal education classes in which midwives prepare expectant parents for delivery. Data include documentation from classes and interviews with the presenters. This twofold dataset enables investigation into how ideologies of communication figure into the production of discourse. A dominant idea is that discourse can stand in for lived experience in the endeavor to decrease nervousness and fear in the expectant parents. The observation data are therefore analyzed by paying attention to how the expectant parents’ future deliveries are discursively represented. Drawing on the conceptual framework for analyzing anticipatory discourse, the study shows how the midwives largely frame this future as predictable and the mother as highly agentive. When addressing unexpected turbulence, however, the midwives use the opportunity to stress the agency of medical professionals to maintain a representation of the delivery event as generally predictable.

Published: November 2017

Purpose

The anti–programmed death-1 antibody pembrolizumab was evaluated in KEYNOTE-028, a multicohort, phase IB study of patients with programmed death ligand-1 (PD-L1)–positive advanced solid tumors. Results from the esophageal carcinoma cohort are reported herein.

Patients and Methods

Eligible patients with squamous cell carcinoma or adenocarcinoma of the esophagus or gastroesophageal junction in whom standard therapy failed and who had PD-L1–positive tumors received pembrolizumab 10 mg/kg every 2 weeks for up to 2 years or until confirmed disease progression or intolerable toxicity. Response was assessed every 8 weeks up to 6 months and every 12 weeks thereafter. Primary end points were safety and overall response rate, determined by investigator review per Response Evaluation Criteria in Solid Tumors (version 1.1).

Results

Among 83 patients with esophageal carcinoma and samples evaluable for PD-L1 expression, 37 (45%) had PD-L1–positive tumors, and 23 were enrolled. Median age was 65 years; 78% had squamous histology; and 87% received ≥ two prior therapies for advanced/metastatic disease. As of the data cutoff (February 20, 2017), median follow-up was 7 months (range, 1 to 33 months). Nine patients (39%) experienced treatment-related adverse events, most commonly decreased appetite, decreased lymphocyte count, generalized rash, and rash (two patients [9%] each). No grade 4 adverse events or deaths were attributed to pembrolizumab. Overall response rate was 30% (95% CI, 13% to 53%); median duration of response was 15 months (range, 6 to 26 months). A six-gene interferon-γ gene expression signature analysis suggested that delayed progression and increased response occur among pembrolizumab-treated patients with higher interferon-γ composite scores.

Conclusion

Pembrolizumab demonstrated manageable toxicity and durable antitumor activity in patients with heavily pretreated, PD-L1–positive advanced esophageal carcinoma.
Validation of a New Method to Automatically Select Cases With Intraoperative Red Blood Cell Transfusion for Audit
Authors: Dexter Franklin , Epstein Richard H. , Ledolter Johannes , Dasovich Susan M. , Herman Jay H. , Maga Joni M. , Schwenk Eric S.
Published: November 2017

BACKGROUND:

Hospitals review allogeneic red blood cell (RBC) transfusions for appropriateness. Audit criteria have been published that apply to 5 common procedures. We expanded on this work to study the management decision of selecting which cases involving transfusion of at least 1 RBC unit to audit (review) among all surgical procedures, including those previously studied.

METHODS:

This retrospective, observational study included 400,000 cases among 1891 different procedures over an 11-year period. There were 12,616 cases with RBC transfusion. We studied the proportions of cases that would be audited based on criteria of nadir hemoglobin (Hb) greater than the hospital’s selected transfusion threshold, or absent Hb or missing estimated blood loss (EBL) among procedures with median EBL <500 mL. This threshold EBL was selected because it is approximately the volume removed during the donation of a single unit of whole blood at a blood bank. Missing EBL is important to the audit decision for cases in which the procedures’ median EBL is <500 mL because, without an indication of the extent of bleeding, there are insufficient data to assume that there was sufficient blood loss to justify the transfusion.

RESULTS:

Most cases (>50%) that would be audited and most cases (>50%) with transfusion were among procedures with median EBL <500 mL (P < .0001). Among cases with transfusion and nadir Hb >9 g/dL, the procedure’s median EBL was <500 mL for 3.0 times more cases than for procedures having a median EBL ≥500 mL. A greater percentage of cases would be recommended for audit based on missing values for Hb and/or EBL than based on exceeding the Hb threshold among cases of procedures with median EBL ≥500 mL (P < .0001). There were 3.7 times as many cases with transfusion that had missing values for Hb and/or EBL than had a nadir Hb >9 g/dL and median EBL for the procedure ≥500 mL.

CONCLUSIONS:

An automated process to select cases for audit of intraoperative transfusion of RBC needs to consider the median EBL of the procedure, whether the nadir Hb is below the hospital’s Hb transfusion threshold for surgical cases, and the absence of either a Hb or entry of the EBL for the case. This conclusion applies to all surgical cases and procedures.
Application of a Schizosaccharomyces pombe Edc1-fused Dcp1–Dcp2 decapping enzyme for transcription start site mapping
Authors: Paquette David R. , Mugridge Jeffrey S. , Weinberg David E. , Gross John D.
Published: November 2017

Changes in the 5′ leader of an mRNA can have profound effects on its translational efficiency with little effect on abundance. Sequencing-based methods to accurately map the 5′ leader by identifying the first transcribed nucleotide rely on enzymatic removal of the 5′ eukaryotic cap structure by tobacco acid pyrophosphatase (TAP). However, commercial TAP production has been problematic and has now been discontinued. RppH, a bacterial enzyme that can also cleave the 5′ cap, and Cap-Clip, a plant-derived enzyme, have been marketed as TAP replacements. We have engineered a Schizosaccharomyces pombe Edc1-fused Dcp1–Dcp2 decapping enzyme that functions as a superior TAP replacement. It can be purified from E. coli overexpression in high yields using standard biochemical methods. This constitutively active enzyme is four orders of magnitude more catalytically efficient than RppH at 5′ cap removal, compares favorably to Cap-Clip, and the 5′ monophosphorylated RNA product is suitable for standard RNA cloning methods. This engineered enzyme is a better replacement for TAP treatment than the current marketed use of RppH and can be produced cost-effectively in a general laboratory setting, unlike Cap-Clip.

First record of Kermes echinatus on Quercus ilex
Authors: Stathas G. J. , Kartsonas E. D. , Skouras P. J.
Published: November 2017

The scale insect Kermes echinatus Balachowsky (Hemiptera, Coccoidea, Kermesidae) was recorded on Quercus ilex in November 2012 in Kalamata and in December of the same year on the same host species in Athens. Quercus ilex is recorded for the first time as the host of this scale. This scale is first recorded in continental Greece. The population of the scale in both areas consisted mainly of first instar nymphs, whereas in Kalamata individuals of the scale in advanced developmental stages were recorded. Preliminary studies indicate that natural enemies are active against K. echinatus. Moultings of larvae and pupae and adults of Chilocorus bipustulatus L. (Coleoptera: Coccinellidae) were found on colonies of the scale. Parasitoid exit holes were recorded on female adults of the scale. Some data on morphology and infestation of the scale on Q. ilex are given.
Reproductive incompatibility between genetically differentiated populations of Tetranychus urticae from different host plants
Authors: Fytrou Natasa , Tsagkarakou Anastasia
Published: November 2017

The study of host plant adaptation in arthropods, and especially agricultural pests, presents great interest, as it relates to patterns of population isolation and differentiation, with effects ranging from gene flow restriction to speciation. Prompted by our earlier isoenzyme studies that revealed genetic differentiation of Tetranychus urticae (Koch) collected on citrus, compared to other host plants, we investigated crossing compatibility between T. urticae collected from citrus (lemon) trees (ELCI) and T. urticae collected from the weed Mercurialis annua (ELMA), in the same citrus grove. Crossing compatibility in haplodiploid species where unfertilised eggs develop into males, like T. urticae, is assessed based on both the number and the sex ratio of the offspring. When ELMA females were crossed with ELCI males, fecundity was not affected, however the sex ratio was significantly biased towards males (16.6 % females, compared to 66% in the control cross ELMAxELMA). In the reciprocal crosses (ELCIxELMA), fecundity was lower by 30% and the proportion of female offspring was reduced to 52% from 67 %, compared to the control. The fecundity of the F1 hybrid females was significantly reduced and the eggs they laid were less viable, compared to the non-hybrids, further reducing the reproductive potential of inter-strain crosses. Combined with previous data, these results suggest the existence of a citrus-associated T. urticae host race.
Pre-plant release enhanced the earlier establishment of Nesidiocoris tenuis in open field tomato
Authors: Perdikis D. Ch. , Arvaniti K. A. , Paraskevopoulos A. , Grigoriou A.
Published: November 2017

The invasive pest of the tomato crops, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), soon after its establishment became a major problem of outdoor and greenhouse tomato crops across the Mediterranean countries. The pre-plant release of the predator Nesidiocoris tenuis (Reuter) (Heteroptera: Miridae) has been found to substantially contribute to its establishment on the crop and efficient control of T. absoluta in greenhouses. The aim of the current study was to assess whether the pre-plant release of N. tenuis could contribute to its earlier establishment. It was concluded that the release of N. tenuis in the nursery contributed substantially in the earlier increase of its numbers in the field in comparison to the control plots. The native populations of M. pygmaeus appeared on the tomato plants before the native populations of N. tenuis. Thus, the conservation of both predators should be taken into consideration in the integrated management strategies against T. absoluta. Therefore, the application of this method in open field tomato crop enhances the earlier establishment of N. tenuis and should be further evaluated in the control of T. absoluta.
First record of the nesting whitefly, Paraleyrodes minei, in Greece
Authors: Kalaitzaki A. P. , Tsagkarakis A. E. , Ilias A.
Published: November 2017

On late June 2015, the nesting whitefly Paraleyrodes minei Ιaccarino (Hemiptera: Aleyrodidae) was recorded for first time in Greece. Its occurrence was observed on leaves of sweet orange [Citrus sinensis (L.) Osbeck] trees at Platanias, Chania, on the underside of which tiny white “nests” were observed, due to the woolly waxy material secreted by females, around themselves, as well as by the filamentous translucent wax rods extending from the dorsum of late nymphal instars. In our surveys P. minei was observed at low or moderate population densities. Information on its morphology, biology and present geographical distribution is provided.

Contribution to the ecological management of the seed chalcid wasp Eurytoma plotnikovi Nikol’skaya (Hymenoptera: Eurytomidae) in pistachio orchards
Authors: Lykouressis D. , Perdikis D. , Biba A.
Published: November 2017

Aspects related to the management of the pistachio seed wasp Eurytoma plotnikovi Nikol’skaya (Hymenoptera: Eurytomidae), were investigated. E. plotnikovi has internal feeding habits. However, the external appearance of the fruits could be used to distinguish between infested and uninfested fruits, since fruits partly blackish or brownish and shriveled had higher infestation levels than those without any discolouration. The adult emergence from the fruits was completed within a short period of 12 days, from the middle until the end of May. This pest overwinters as larva inside the mummified fruits. The application of sanitation measures for the control of this pest was experimentally investigated. The results showed that no adults emerged from fruits that were buried in the soil but also from those that remained on the soil surface during winter. Thus, it seems that there is no need for burying them by tillage under the soil as it had been proposed. This result might be essential in the wider adoption of this method in the management of this pest.
The occurrence of Rhynchophorus ferrugineus in Greece and Cyprus and the risk against the native greek palm tree Phoenix theophrasti

Published: November 2017

The red palm weevil (RPW), Rhynchophorus ferrugineus (Coleopiera: Curculionidae), is the most important pest of palm trees in the world. In the last decade R. ferrugineus has invaded the Mediterranean basin where it causes severe damage in date palm cultivations as well as in ornamental palm trees. R. ferrugineus has been found for first time in Greece in Hersonissos (Heraklion district, Crete) infesting Phoenix canariensis, on November 11th, 2005 and for first time in Cyprus in Limassol district on August 20th, 2006, infesting also P. canariensis. Afterwards, R. ferrugineus has been found in Rhodos island, Greece, on 15/9/2006 and in Oropos and Ellinikon (Attiki district, Greece) on 5/12/2006 and 27/12/2006 respectively, infesting mainly P. canariensis. In Cyprus it has also been found in October 2006 in Larnaca, Famagusta and Paphos districts. In laboratory experimentation the susceptibility of the native Greek palm tree Phoenix theophrasti in R. ferrugineus was proved.
Electroantennogram responses from olfactory receptors in Dαcus oleαe

Published: November 2017

Substances found in Dacus oleae (Gmelin) (Diptera: Tephritidae) male or female flies which have been reported as pheromones, i.e. elicit some form of biological activity in laboratory or field bioassays, were tested with the electroantennogram technique (EAG). Substances of non-insect origin were also tested as possible pheromone candi­dates. All substances of insect or non-insect origin elicited an EAG response to both sexes of lab-cultured or wild insects but 1,7 dioxaspiro [5,5] undecane, the major pheromone component, has a lower response threshold value than all other compounds. At the maximum stimulus concentration the response to nonanal reaches a value higher than that elicited by all other compounds. EAG responses to various compounds, after receptor adaptation to the major pheromone compound and nonanal, showed that these two compounds are detected by different sets of receptors. Other comments on the sensitivity and specificity of antennal receptors are also presented.
Notes on life history and field efficiency of Cybocephαlus fodori predator of Quαdrαspidiotus perniciosus in Northern Greece
Authors: Katsouannos Ρ.
Published: November 2017

Sampling results during 1978-1979 and 1981-1982 in two heavily-infested almond orchards in Northern Greece showed a high mortality of the San Jose scale. A considerable part of this mortality was attributable to indigenous entomophagous insects, especially predators. Among them, Cybocephalus fodori Endrody-Younga (Coleoptera: Nitidulidae) appeared to be the key species. Field observations showed that C. fodori hibernates as an adult, forming aggregations. C. fodori reared in outdoor cages showed full adult activity by end March. Given an abundant supply of prey, the insect develops two complete and a third partial generations per year. Under constant conditions (25±2° C, 65±5% R.H. and 16 hrs light per day), the development of its three larval instars was completed in about 19 days and the pupal stage lasted about 10 days. On average, 68 Quadraspidiotus perniciosus Comstock (Homoptera: Diaspididae) adult females were partly consumed per larva of C. fodori. Individually deposited eggs and young larvae were found under the covers of the San Jose scales.
Parthenolecanium corni (Bouche), an orchard scale pest producing honeydew foraged by bees in Greece
Authors: Santas L.A.
Published: November 2017

The soft scale Parthenolecanium corni (Bouch6), a pest of filbert tree and other hosts, is a useful insect for apiculture in Greece. It excretes honeydew which is exploited by honeybees in April, May and early June. The scale has one generation per year, and overwinters as a second instar nymph. Adults appear early in April and crawlers in the middle of June. From mid June to mid July, the population of P. corni consists mainly of crawler-, and/or first instar nymphs. The second instar nymphs appear in mid July and by the end of October all the scale population is in this stage. The period from July to February, is long enough to permit the application of insecticides to control the scale, without causing any harm to the bees.
Flight period of some parasitoids and a predator of the olive black scale (Saissetia oleae Olivier) on Corfu island

The time of year the adults (flight period) of the parasitoids of S. oleae: Μetaphycus helvolus, Μetaphycus lounsburyi, Scutelista cyanea and Moranila californica and the predator Chilocorus bipustulatus are present, was determined in three areas of Corfu island: Lima, Kontocali and Avliotes. M. helvolus apparently has two flight periods: the first is from A­pril till July and the second from November till December. All the other natural enemies have only one flight period per year. The flight period of M. lounsburyi is from April till August, while S. cyanea flies from August till the end of September or the first days of Oc­tober, and M. californica adults are present from July till the middle of December. Adults of C. bipustulatus appeared from July till December or the middle of January.
Influence of the Leguminosae secondary substances on the ecology and biology of Bruchidae
Authors: Stamopoulos D.C.
Published: November 2017

Secondary substances of leguminous seeds, suggest themselves to be the main defense mechanisms against Bruchidae which also develop their own mechanisms to avoid and/or detoxify these compounds. These interactions between plants and insects through the secondary substances, lead to the appearance of divergent or convergent defence mechanisms at the plant level and to the specialist or generalist at the insect one. Among the most widespread secondary compounds in the Leguminosae, are the tannins, lignins, lectins, alkaloids, enzyme inhibitors, polysaccharides, non protein amino acids, toxic glycosides and miscellaneous toxins
Determination of spray dates for the control of the first generation of Quadraspidiotus perniciosus in Northern Greece
Authors: Kyparissoudas D.S.
Published: November 2017

During 1986-1988 the relationship between catches of San Jose scale (SJS), Quadraspidiotus perniciosus (Comstock), adult males in pheromone traps and crawlers on sticky-tape traps was studied as a basis of SJS crawler control in apple orchards of Northern Greece. Spring male flight began in mid-to late April and crawler emergence occurred in mid-to late May. Crawlers were active for a period of 6-7 weeks until early July. Peak crawler emergence occurred approximately 12 days after the first emergence, or 42 days after the first males were captured on pheromone traps. Because in our 3-year study the crawler emergence occurred 29-31 days or 191-202 day-degrees (base 10.5°C) after the capture of the first male, we conclude that a consistent time-relationship exists between the two events. Two insecticide treatments, one three days after the first crawler appearance and another 10 days later (near peak crawler activity), provided the best control against the first generation of scale.

Aphid species abundance was studied by means of yellow Moericke water traps in several tobacco fields in two tobacco growing areas, Aitoloakarnania and Pieria, Greece. In 1992, from alate catches, in three different localities in Aitoloakarnania, a total number of 69, 40 and 31 taxa were caught and identified. Five of them are new records for the Greek aphidofauna. In 1993, from the traps established near Agrinio and in Nea Ephessos, Pieria, a total number of 55 and 139 aphid taxa were caught and identified. Twenty one of them aphid species are new records for Greece of which 3 had been already recorded in the previous year. In total, 23 aphid species recorded for the first time in Greece are presented in this work.
Geographic Variation of Diapause Induction and Termination in the Spider Mite Tetrαnychus urticαe: Α mini-review
Authors: Koveos S. , Veerman A.
Published: November 2017

In eight strains of the spider mite Tetranychus urticae Koch (Acari: Tetranychidae), originating from different localities in Europe, the critical daylength for diapause induction and termination was almost the same in each strain but varied with the latitudinal origin of the strains; critical daylength was shorter in strains originating from lower latitudes and longer in those from higher latitudes. Diapause intensity, measured as the period of chilling required for diapause termination under a short day photoperiod (LD 10:14) and 19°C, again varied with the latitudinal origin of each strain, being higher the more northern the origin of the strain. An exception were two mountain strains which showed a longer critical daylength and a deeper diapause than expected on the basis of their latitudinal origin. The number of long-day (LD 17:7) cycles required for 50% diapause termination after a certain period of chilling was higher in the northern and lower in the southern strains. These results indicate that geographic strains of T urticae may differ considerably in their diapause attributes, which may be explained as an adaptation to local climatic conditions. The great plasticity of the diapause response may, among other factors, have been responsible for the wide distribution of this mite species.

Leaf Preference of Heliothrips hαemorrhoidαlis (Thysonoptera: Thripidae) on Vιburnum tinus
Authors: Koufos V. Α. , Perdikis D. CH.
Published: November 2017

The leaf preference of larvae, pupae and adults of Heliothrips haemorrhoidalis (Buche) (Thysanoptera: Thripidae), a serious pest of several ornamental plants, were studied on Viburnum tinus. Leaves were sampled for thrips from the base, middle and distal end of viburnum twigs at weekly intervals from April 11 to September 15, 2000. The population of this thrips was observed at high levels of between 10 to 76 thrips per leaf, till the middle of June when it sharply declined to zero, probably due to high temperatures. Higher populations developed on the basal than on the middle leaves. The lowest populations were recorded on the distal leaves. The predator Orius vicinus (Ribaut) (Hemiptera: Anthocoridae) was recorded in low numbers and therefore its effect on thrips populations was considered negligible.

The effect of temperature οη the development of the predators Nephus includens (Kirsch) and Ν. bisignatus (Boheman) (Coleoptera: Coccinellidae), was studied. The development time of immature stages and the pre-oviposition period of adult females for the two predators was recorded at eight constant temperatures (10, 15, 20, 25, 30, 32.5, 35 and 37.5°C). The beetles were reared on eggs, nymphs and female adults of Planococcus citri (Risso) (Homoptera: Pseudococcidae) that had developed on squash (Cucurbita pepo) and on sour orange leaves (CΊtrus aurantium). Using the linear model for the biological cycle of Ν. includens on squash and on sour orange leaves, the developmental zeros (lower temperature thresholds) were estimated to be 10.9 and 11.0°C respectively and the thermal constants, 490.5 and 472.8 day-degrees respectively. Using the Lactin model the lower thresholds were estimated to be 11.1 and 11.2°C respectively and the upper thresholds 36.1 and 36.0°C respectively. For the biological cycle of Ν. bisignatus, using the linear model, the lower thresholds were estimated to be 9.4°C on squash and 9.3°C on sour orange leaves and the thermal constants were 614.3 and 647.9 day-degrees respectively. Using the Lactin model the lower thresholds were estimated to be 9.9 and 1O.0°C respectively and the upper thresholds, 34.7 and 35.0°C respectively. The survival rate of Ν. includens in­stars at 10, 15, 20, 25, 30, 32.5, 35 and 37.5°C on squash and on sour orange leaves was respectively 0.0, 34.9, 63.2, 70.6, 63.3, 54.5, 19.8, 0.0, and 0.0, 32.2, 61.0, 68.0, 68.3, 56.6, 17.6, 0.0%. The survival rate of Ν. bisignatus instars at 10, 15, 20, 25, 30, 32.5 and 35°C on squash and on sour orange leaves was respectively, 0.0, 39.9, 61.1, 60.7, 47.2, 26.4, 0.0 and 0.0, 35.7, 65.7, 68.0, 44.2, 29.1, 0.0%. The results show that Ν. includens has a shorter biological cycle than Ν. bisignatus, whereas the latter species has lower temperature thresholds.

Firm Expansion, Size Spillovers, and Market Dominance in Retail Chain Dynamics
Authors: Blevins Jason R. , Khwaja Ahmed , Yang Nathan
Published: November 2017

We develop and estimate a dynamic game of strategic firm expansion and contraction decisions to study the role of firm size in future profitability and market dominance. Modeling firm size is important because retail chain dynamics are more richly driven by expansion and contraction than de novo entry or permanent exit. Additionally, anticipated size spillovers may influence the strategies of forward-looking firms, making it difficult to analyze the effects of size without explicitly accounting for these in the expectations and, hence, decisions of firms. Expansion may also be profitable for some firms while detrimental for others. Thus, we explicitly model and allow for heterogeneity in the dynamic link between firm size and profits as well as potential for persistent brand effects through firm-specific unobservable factors. As a methodological contribution, we surmount the hurdle of estimating the model by extending a two-step procedure that circumvents solving the game. The first stage combines semiparametric conditional choice probability estimation with a particle filter to eliminate the serially correlated unobservable components. The second stage uses a forward simulation approach to estimate the payoff parameters. Data on Canadian hamburger chains from their inception in 1970 to 2005 provide evidence of firm-specific heterogeneity in brand effects, size spillovers, and persistence in profitability. This heterogeneous dynamic linkage shows how McDonald’s becomes dominant and other chains falter as they evolve, thus affecting market structure and industry concentration.

Apontamentos sobre a imagética animal na Literatura Grega: a caracterização do herói e o símbolo da cadela e do lobo
Authors: Ferreira Nelson Henriques Henriques
Published: November 2017

Seja pela excelência em combate, solução de enigmas, edificação de cidades ou mesmo limpeza de estábulos, ao herói associava-se o extraordinário, a condição social ou etiológica especial, a capacidade de superar provas que só a imaginação poderia conceber. Por tal, a memória narrativa do herói antigo sobrevive à passagem do tempo e até ao desaparecimento da cultura que lhe deu origem, através da tradição popular ou pela cristalização da arte de expressão. Ora, pretende-se com este breve ensaio identificar alguns dos mecanismos usados no processo da criação do herói no imaginário coletivo, mais precisamente aqueles que envolvem a imagética animal e a significação simbólica a ela associada, no contexto das culturas do mediterrâneo - tomando essencialmente as fontes literárias como fundamento. Nesse sentido, o nosso objetivo será debater o modo como a imagética animal potenciou e singularizou a concepção do herói e, ao mesmo tempo, explorar o meio e o motivo pelos quais a simbologia animal se cristalizou de forma quase universal.
Políticas educacionais nas prescrições para o Ensino Médio: dimensões para o ensino de leitura
Authors: Stutz Lidia , Cristovão Vera Lucia Lopes
Published: November 2017

Este artigo tem o objetivo de mapear as dimensões de linguagem explicitadas em prescrições educacionais brasileiras de Ensino Médio, a fim de compreender quais são os direcionamentos dados aos docentes para a prática de ensino para a compreensão escrita em línguas estrangeiras (LEs) e em língua portuguesa como língua materna (LPLM). A partir deste levantamento analisamos se as propostas para ambas as línguas aproximam-se ou mostram caminhos distintos para o enfoque da compreensão escrita. O caráter documental do estudo tem como corpus seis importantes documentos que regem o currículo escolar para o referido nível nas duas últimas décadas: Parâmetros Curriculares Nacionais para o Ensino Médio (BRASIL, 2000), Orientações Curriculares para o Ensino Médio (BRASIL, 2006), Diretrizes Curriculares do Estado do Paraná- Língua Portuguesa e Língua Estrangeira Moderna (PARANÁ, 2008), Base Nacional Comum Curricular (BRASIL, 2016), Matriz de Referência do Exame Nacional do Ensino Médio- ENEM (BRASIL, s.d.), Guia de Livros Didáticos: PNLDEM (BRASIL, 2015). A proposta para o trabalho didático com leitura nos documentos ancora-se na concepção de linguagem como fenômeno social e de interação verbal. Classificamos os elementos propostos nos documentos em ordem descendente em cinco dimensões: macro e microcontextual, organizacional, linguístico-enunciativa e cognitiva. Além dessas, duas outras dimensões foram categorizadas como: multimodais e digitais. Observamos que há maior fluidez nas propostas das duas línguas em aspectos microcontextuais e em alguns elementos linguístico-enunciativos. Embora haja interesse em propostas inter- ou transdisciplinares, nas demais dimensões não há maior aproximação nos documentos para facilitar e fortalecer a prática docente e contribuir para aprimorar as capacidades de linguagem discente.
Confessions of Novice Designers and Their Instructor
Authors: Dousay Tonia A. , LaVanchy Jennifer , Kilty Trina , Stone Dillon
Published: November 2017

These three condensed design cases provide a glimpse of the decisions undertaken by novice designers in a graduate-level message design course. The course helps students examine the role of communication theory, cognitive psychology, cultural influence, and design skills within the context of instructional messages both in theory and through practical application. Practical application in the course includes smaller design projects to gain experience with best practices and recommendations, and the course culminates with a service learning project that pairs students with a community partner. The community partner provides basic specifications for a specific need, and the students then design artifacts to meet these requirements. The assignment is evaluated based of how well students followed client specifications, design considerations for each medium, content and grammar mechanics, copyright guidelines, and general design principles. However, the students also compete in the sense that the client selects which artifacts to implement from among those submitted. Embedded within each design case are instructor reflection comments that address particular or repetitive themes that emerged from each designer. Combined, these cases help identify course design weaknesses and bring clarity to concerns regarding how to help novice designers progress in competency.

Increasing the stability of dental implants: The concept of osseodensification
Authors: Podaropoulos Leonidas
Published: November 2017

One of the most important factors that affect osseointegration is the primary stability of the implant. Dental implants inserted at the posterior region of the maxilla exhibit the lowest success rates as the low density bone in this area often jeopardize rigid fixation of the implant. Many surgical techniques have been developed to increase the primary stability of an implant placed in low density bone, such as bicortical fixation of the implant, undersized preparation of the implant bed and bone condensation by the use of osteotomes. A new promising technique, named osseodensification, has been recently developed that creates an autograft layer of condensed bone at the periphery of the implant bed by the aid of specially designed burs rotating in a clockwise and anti-clockwise direction. The purpose of this review is to emphasize that implant primary stability is strongly influenced by the surgical technique, to quote and briefly analyse the various surgical procedures laying weight to osseodensification procedure.

Published: November 2017

This review paper occupies with the frequency, etiology, diagnosis, treatment and the possible complications of Ankyloglossia (AG). AG is a congenital anomaly and its range varies from 0,1% to 4,8 %. There are several methods for the diagnosis of AG. The most popular method is the ‘’Hazelbaker’’, which assesses seven different tongue movements and five appearance characteristics. As far as the management of AG is concerned, there are two options, the ‘’wait-and-see’’ and the invasive procedure. The operator can choose between the frenotomy and the frenectomy. The difference is that in frenectomy the clinician removes the whole frenulum. Few complications have been mentioned, such as ulcers, pain, bleeding and noticeable scar, which were brought on to a second operation.

Published: November 2017

Background/Aim: The aim of the present study was to investigate the treatment options, survival rate of traumatized primary teeth and evaluate the factors influencing the outcome. Material and Methods: The sample consisted of all dental trauma cases treated over a 14 years period at the Department of Pediatric and Preventive Dentistry, Dental Clinic of Vojvodina, Novi Sad. Criteria for inclusion in this study were: dental trauma to primary teeth and age in the moment of injury up to seven years. Dental trauma records were analyzed in order to obtain the following: gender and age of the child at the time of trauma, type of trauma, as well as the type and timing of treatment received. After data analysis a survival rate of traumatized primary teeth was evaluated. Results: The study was designed as retrospective and it included 225 children, with 346 traumatized primary teeth. The occurrence of trauma was higher in male patients (60,4%) and in children up to 4 years of age. Luxations were more frequent (72.8%) compared to isolated teeth fractures (20.8%), while the two types of injury combined were rare (6,3%). One year following dental trauma 231 teeth (0.67%) developed complications. Falls were the main cause of trauma (68.9%) and the presence of more than one traumatized tooth was frequent. A percentage of 48.8 children received dental care during first 24 h after the injury. Conclusions: Survival of injured primary teeth is relatively low, regardless of trauma type, time interval between injury and treatment and the type of provided treatment.
Gingival crevicular fluid levels of prolidase and alkaline phosphatase in periodontitis
Authors: Guven Berrak , Turer Cigdem
Published: November 2017

Background/Aim: The purpose of this study was to investigate gingival crevicular fluid (GCF) alkaline phosphatase (ALP) and prolidase levels in subjects with different periodontal status. Material and Methods: Fifteen periodontitis, fifteen gingivitis and fifteen healthy subject were included. GCF samples were collected from participants. Probing depth, clinical attachment level, gingival index was recorded. ALP and prolidase levels were determined in GCF by spectrophotometrically. Results: Higher values of ALP were found in periodontitis compared with gingivitis and healthy control (p<0.001). The values of prolidase were lower in periodontitis than healthy control (p<0.05). A statistically significant positive correlation was found between clinical parameters and ALP levels (p<0.001). There is no significant correlation between clinical parameters and prolidase levels (p>0.05). Additionally, no significant correlation was detected between ALP and prolidase (r= -0.309, p>0.05). Conclusion: Our preliminary data suggest that low prolidase level in periodontitis was not associated with ALP and clinical parameters, which represent periodontal destruction and inflammation.

Background/Aim: Class III malocclusion case are considered complex problems associated with unacceptable esthetics. The purpose of the present study was to assess the characteristics of the soft tissue profile and investigate the possible gender differences in adult Greeks with Class III malocclusion. Material and Methods: The material of the study comprised of 57 pretreatment lateral cephalograms of adult patients with Class III malocclusion aged 18 to 39 years. Eleven variables were assessed. The variables were measured and the mean, minimum and maximum and standard deviations were calculated. Parametric and non-parametric tests were used to compare males and females patients. Results: The total sample was characterized by concave skeletal profile. Male patients exhibited greater nose prominence and superior sulcus depth, longer distance from subnasale to the harmony line, more concave profile, thicker upper lip and larger upper lip strain. Conclusions: Many significant differences were noted in soft tissue characteristics between males and females with skeletal Class III malocclusion, suggesting possible gender dimorphism.

Published: November 2017

Background/Aim: Lately, fully innovative sol-gel method with high-temperature self-propagating reaction was used for the synthesis of new nanostructured endodontic materials, in combination with different radiopacifiers: bismuth (ALBO-MPCA1) and barium (ALBO-MPCA2). The aim of this study was to investigate the biocompatibility of nanostructured endodontic materials based on highly active calcium silicates and mixed with different radiopacifiers in comparison to MTA+ using human stem cells from the apical papilla- SCAP cells. Material and Methods: Morphology of the samples was studied by SEM. The tested materials were mixed with distilled water in a ratio 2:1 (m/m). Fifteen minutes after the preparation, samples were used in the experiment. The biocompatibility of fresh materials, after 3h and 7 days, was tested using 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide- MTT test. Results: Samples mostly consisted of spherical and rode-like. The relative viability of cells increased following the exposure time. Conclusion: The biocompatibility of synthesized materials is comparable to the control material MTA+, and therefore these materials can be recommended for further clinical studies.
