Social Media as a Channel of Constructive Dialogue for Tourism Businesses
Authors: Sotiriadis Marios D.
Published: October 2018

The main aim of this chapter is to examine and suggest the ways in which tourism businesses could take advantage of social media (SM) as a channel of interactive communication and constructive dialogue with customers. More specifically, it examines the potential contribution and possible uses of SM by tourism providers in acquiring customer feedback. It is based on extensive reviews of literature and business reports. It takes a strategic and operational marketing perspective to analyze the potential contribution of SM from the point of view of tourism providers. SM are regarded as a source of, and medium for, interactive communication with customers.
Virtual Tourism and Its Potential for Tourism Development in Sub-Saharan Africa
Authors: Ankomah Paul , Larson Trent
Published: October 2018

Rapid growth of ICT has resulted in the development of innovative tools that could extend opportunities for tourism destination marketers and tourists. ICT-based tools expand the tourism product and tourism experience into the realm of virtual tourism (VT). Since the tourism product is intangible and cannot be pretested by tourists before purchase, VT makes it possible to sense the experience through virtual reality (VR). This chapter focuses on how VT could be explored to realize its full potential, particularly by Sub-Saharan African countries. The first section reviews the literature on VR and its relationship to VT and examines ICT components that support VR and VT. The second section explains reasons for interest in VT and identifies development efforts. The third section examines tourist attractions that could be marketed as VT in the sub-region and also identifies markets. The fourth section identifies problems and makes suggestions to address problems in VT development. The fifth section recommends areas for VT research, and the final section provides concluding remarks.
The Impact of Artificial Intelligence and Virtual Personal Assistants on Marketing
Authors: McDowell Marinchak Christina L. , Forrest Edward , Hoanca Bogdan
Published: October 2018

This chapter will review the state of the art in AI, with a particular focus on applications in marketing. Based on the current capabilities of AI in marketing, the authors explore the new rules of engagement. Rather than simply targeting consumers, the marketing effort will also be directed at the algorithms controlling the consumers' virtual personal assistants (VPAs). Rather than exploiting human desires and weaknesses, marketing will need to focus on meeting the user's actual needs. The level of customer satisfaction will be even more critical as marketing will need to focus on establishing and maintaining a reputation in competition with those of similar offerings in the marketplace. This chapter concludes with thoughts on the long-term implications, exploring the role of customer trust in the adoption of AI agents, the security requirements for agents, and the ethical implications of access to such agents.
Big Data and Simulations for the Solution of Controversies in Small Businesses
Authors: Janakova Milena
Published: October 2018

The global information society creates data in various formats, and data is stored in many sources. Interest is focused on true story formation with respect to sustainable development. The suitable recommendation is to implement a multidimensional view on big data. Such an approach works with big data on three levels. The basic level represents default activities and analyses for data storage in data warehouse. The advanced level is focused on searching for links between stored data and information sources in the global society, and variable level searches unexpected events based on complex statistics and mathematical methods with the support of artificial intelligence, business intelligence, customer intelligence, competitive intelligence, swarm intelligence. These kinds of activities are important for IT product development such as specification of the road for an adopted methodology, definition of a reference for needed dimensions and phases for IT development, and also as a warning against omissions and mistakes.
Financing Micro, Small, and Medium Enterprises in Indian Industry
Authors: Ganguly Shromona
Published: October 2018

During the last five decades, the micro, small, and medium enterprises (MSME) in the Indian economy have emerged as a dynamic, vibrant segment having a significant contribution towards employment generation and entrepreneurship formation. Despite being an important contributor towards the national output and employment of the economy, the MSME sector continues to face a number of challenges choking its growth, of which credit availability to these enterprises has become one of the most important issues. The existing literature on small firm financing discusses the issues and challenges from a cross-country perspective. There is a lack of detailed research on implications of country-specific factors and financial system on small firm financing. The chapter aims to fill this gap by analyzing the extent and nature of credit constraint faced by small firms in the manufacturing sector in India and how technology may change the situation in the coming years.
150 years of new beetles (Coleoptera) described in The Canadian Entomologist and associated publications (1868–2017)
Authors: Bouchard P. , Brunke A.J. , Davies A.E. , Douglas H. , Smith A.B.T. , Manoogian J.
Published: October 2018

The Canadian Entomologist and its associated publications (Supplements of The Canadian Entomologist and Memoirs of the Entomological Society of Canada) have served as important outlets for taxonomic contributions on arthropods since 1868. A survey of beetle (Coleoptera) publications therein has revealed that 2276 species-group, 136 genus-group, and seven family-group taxa were first described in 492 scientific articles. New beetles were described in 67 families by 165 authors. We document trends of beetle descriptions over time, by taxonomic group and by the origin of the new taxa. We also provide biographical notices of the entomologists who described the new taxa. We believe that The Canadian Entomologist will continue to be coveted as a suitable outlet for taxonomic works in the future.
ABIN2 Function Is Required To Suppress DSS-Induced Colitis by a Tpl2-Independent Mechanism

Published: October 2018

The A20-binding inhibitor of NF-κB 2 (ABIN2) interacts with Met1-linked ubiquitin chains and is an integral component of the tumor progression locus 2 (Tpl2) kinase complex. We generated a knock-in mouse expressing the ubiquitin-binding–defective mutant ABIN2[D310N]. The expression of Tpl2 and its activation by TLR agonists in macrophages or by IL-1β in fibroblasts from these mice was unimpaired, indicating that the interaction of ABIN2 with ubiquitin oligomers is not required for the stability or activation of Tpl2. The ABIN2[D310N] mice displayed intestinal inflammation and hypersensitivity to dextran sodium sulfate–induced colitis, an effect that was mediated by radiation-resistant cells rather than by hematopioetic cells. The IL-1β–dependent induction of cyclooxygenase 2 (COX2) and the secretion of PGE2 was reduced in mouse embryonic fibroblasts and intestinal myofibroblasts (IMFs) from ABIN2[D310N] mice. These observations are similar to those reported for the Tpl2 knockout (KO) mice (Roulis et al. 2014. Proc. Natl. Acad. Sci. USA 111: E4658–E4667), but the IL-1β–dependent production of COX2 and PGE2 in mouse embryonic fibroblasts or IMFs was unaffected by pharmacological inhibition of Tpl2 in wild-type mice. The expression of ABIN2 is decreased drastically in Tpl2 KO mice. These and other lines of evidence suggest that the hypersensitivity of Tpl2 KO mice to dextran sodium sulfate–induced colitis is not caused by the loss of Tpl2 catalytic activity but by the loss of ABIN2, which impairs COX2 and PGE2 production in IMFs by a Tpl2 kinase–independent pathway.
Estrogen Signaling in Bystander Foxp3neg CD4+ T Cells Suppresses Cognate Th17 Differentiation in Trans and Protects from Central Nervous System Autoimmunity

Published: October 2018

17β-Estradiol (E2) suppresses the development of experimental autoimmune encephalomyelitis (EAE) through estrogen receptor (ER) α, yet the cellular targets remain elusive. We have used an adoptive transfer model of myelin oligodendrocyte glycoprotein–specific CD4+ T cells from 2D2 TCR transgenic mice. We show that in the recipient mice, ERα expression in bystander CD4+ T cells, rather than in cognate 2D2 T cells, is required for the inhibition of Th17 cell differentiation by E2. Coadministration of estrogen-primed WT, but not ERα-deficient CD4+ T cells, with naive 2D2 T cells lacking ERα inhibited the development of Th17 cell–mediated EAE. Suppression of Th17 cells and protection from EAE were maintained when ERα was deleted in Foxp3+ regulatory T cells. We showed that in vivo PD-L1 blockade alleviated the anti-inflammatory action of E2 and that PD-1 expression on cognate but not bystander T cells was required for the E2-dependent inhibition of Th17 differentiation. In cotransfer experiments, we found that only WT but not PD-1KO 2D2 T cells were amenable to E2-dependent inhibition of Th17 differentiation. These results support the conclusion that the restriction of Th17 cell development by E2-primed bystander CD4+ T cells requires cell-intrinsic PD-1 signaling within cognate T cells rather than induction of regulatory 2D2 T cells through PD-1 engagement. Altogether, our results indicate that pregnancy-level concentrations of estrogen signal in conventional Foxp3neg CD4+ T cells to limit the differentiation of cognate Th17 cells through a trans-acting mechanism of suppression that requires a functional PD-1/PD-L1 regulatory axis.
Thermal Stress Analysis for High CRI LED Indoor Lighting Module
Authors: Lee Jonghwan , Kwon Ki-Youn
Published: October 2018

This research is for developing a new light emitting diode (LED) indoor lighting module with high color rendering index greater than 95. When the LED is operated, electrical energy is generated and heat is released. The failing of heat dispersal degrades the performance and decreases the operating life. To manage the thermal problem effectively, several approaches have been tested in this research study. A heat sink is designed to absorb and transfer heat from the LED module. To analyze the heat flow and thermal stress of the designed LED products effectively, hexahedral mesh generation has been implemented. Heat transfer analysis was performed to find an optimal conductive material. The outcomes of this research study suggest the best material for LED products and show the result of thermal transfer simulation.

Authors: Halestrap Peter , Scheenstra Sue
Published: October 2018

Over a five-month period, clinicians in Tana River County Kenya observed an increasing number of patients presenting to health facilities with a common collection of symptoms including fevers, joint pains and gum hypertrophy. After initial investigative and management strategies failed to reveal a diagnosis, patients were empirically commenced on ascorbic acid for presumed scurvy. This strategy resulted in the rapid resolution of symptoms in 65 patients within two weeks.
Differentiation of breast tuberculosis and breast cancer using diffusion-weighted, T2-weighted and dynamic contrast-enhanced magnetic resonance imaging
Authors: Ramaema Dibuseng P. , Hift Richard J.
Published: October 2018

Background: The use of multi-parametric magnetic resonance imaging (MRI) in the evaluation of breast tuberculosis (BTB).Objectives: To evaluate the value of diffusion-weighted imaging (DWI), T2-weighted (T2W) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in differentiating breast cancer (BCA) from BTB.Method: We retrospectively studied images of 17 patients with BCA who had undergone preoperative MRI and 6 patients with pathologically proven BTB who underwent DCE-MRI during January 2014 to January 2015.Results: All patients were female, with the age range of BTB patients being 23–43 years and the BCA patients being 31–74 years. Breast cancer patients had a statistically significant lower mean apparent diffusion coefficient (ADC) value (1072.10 +/- 365.14), compared to the BTB group (1690.77 +/- 624.05, p = 0.006). The mean T2-weighted signal intensity (T2SI) was lower for the BCA group (521.56 +/- 233.73) than the BTB group (787.74 +/- 196.04, p = 0.020). An ADC mean cut-off value of 1558.79 yielded 66% sensitivity and 94% specificity, whilst the T2SI cut-off value of 790.20 yielded 83% sensitivity and 83% specificity for differentiating between BTB and BCA. The homogeneous internal enhancement for focal mass was seen in BCA patients only.Conclusion: Multi-parametric MRI incorporating the DWI, T2W and DCE-MRI may be a useful tool to differentiate BCA from BTB.
Comparison Geometry of Manifolds with Boundary under a Lower Weighted Ricci Curvature Bound

Published: October 2018

We study Riemannian manifolds with boundary under a lower weighted Ricci curvature bound. We consider a curvature condition in which the weighted Ricci curvature is bounded from below by the density function. Under the curvature condition and a suitable condition for the weighted mean curvature for the boundary, we obtain various comparison geometric results.

defined by a characteristic polynomial for the system. The results are first proved for a constant coefficient system and then for an almost constant coefficient system. The results are applied to a number of examples including the complex hydrogen atomand the complex relativistic electron.
Eigensystem multiscale analysis for Anderson localization in energy intervals
Authors: Elgart Alexander , Klein Abel
Published: October 2018

We present an eigensystem multiscale analysis for proving localization (pure point spectrumwith exponentially decaying eigenfunctions, dynamical localization) for the Anderson model in an energy interval. In particular, it yields localization for the Anderson model in a nonempty interval at the bottom of the spectrum. This eigensystem multiscale analysis in an energy interval treats all energies of the finite volume operator at the same time, establishing level spacing and localization of eigenfunctions with eigenvalues in the energy interval in a fixed box with high probability. In contrast to the usual strategy, we do not study finite volume Green’s functions. Instead, we perform a multiscale analysis based on finite volume eigensystems (eigenvalues and eigenfunctions). In any given scale we only have decay for eigenfunctions with eigenvalues in the energy interval, and no information about the other eigenfunctions. For this reason, going to a larger scale requires new arguments that were not necessary in our previous eigensystem multiscale analysis for the Anderson model at high disorder, where in a given scale we have decay for all eigenfunctions.
Perturbations of globally hypoelliptic operators on closed manifolds
Authors: de Ávila Silva Fernando , Kirilov Alexandre
Published: October 2018

Analyzing the behavior at infinity of the sequence of eigenvalues given by matrix symbol of a invariant operator with respect to a fixed elliptic operator, we obtain necessary and sufficient conditions to ensure that perturbations of globally hypoelliptic operators continue to have this property. As an application, we recover classical results about perturbations of constant vector fields on the torus and extend them for more general classes of perturbations. Additionally, we construct examples of low order perturbations that destroy the global hypoellipticity, in the presence of diophantine phenomena

Published: October 2018

Abstract. Cold regions hydrology is very sensitive to the impacts of climate warming. Future warming is expected to increase the proportion of winter precipitation falling as rainfall. Snowpacks are expected to undergo less sublimation, form later and melt earlier and possibly more slowly, leading to earlier spring peak streamflow. More physically realistic and sophisticated hydrological models driven by reliable climate forcing can provide the capability to assess hydrologic responses to climate change. However, hydrological processes in cold regions involve complex phase changes and so are very sensitive to small biases in the driving meteorology, particularly in temperature and precipitation. Cold regions often have sparse surface observations, particularly at high elevations that generate a major amount of runoff. The effects of mountain topography and high latitudes are not well reflected in the observational record. The best available gridded data in Canada is from the high resolution forecasts of the Global Environmental Multiscale (GEM) atmospheric model and the Canadian Precipitation Analysis (CaPA) but this dataset has a short historical record. The EU WATCH ERA-Interim reanalysis (WFDEI) has a longer historical record, but has often been found to be biased relative to observations over Canada. The aim of this study, therefore, is to blend the strengths of both datasets (GEM-CaPA and WFDEI) to produce a less-biased long record product (WFDEI-GEM-CaPA). First, a multivariate generalization of the quantile mapping technique was implemented to bias-correct WFDEI against GEM-CaPA at 3 h × 0.125° resolution during the 2005–2016 overlap period, followed by a hindcast of WFDEI-GEM-CaPA from 1979. The final product (WFDEI-GEM-CaPA, 1979–2016) is freely available at the Federated Research Data Repository (https://doi.org/10.20383/101.0111).
Influence of snow water equivalent on droughts and their prediction
in the USA
Authors: Abel Daniel , Pollinger Felix , Paeth Heiko
Published: October 2018

Abstract. Droughts can result in enormous impacts for environment, societies, and economy. In arid or semiarid regions with bordering high mountains, snow is the major source of water supply due to its role as natural water storage. The goal of this study is to examine the influence of snow water equivalent (SWE) on droughts in the United States and find large-scale climatic predictors for SWE and drought. For this, a Maximum Covariance Analysis (MCA), also known as Singular Value Decomposition, is performed with snow data from the ERA–Interim reanalysis and the self-calibrating Palmer Drought Severity Index (sc–PDSI) as drought index. Furthermore, the relationship of resulting principal components and original data with atmospheric patterns is investigated. The leading mode shows the spatial connection between SWE and drought via downstream water/moisture transport. Especially the Rocky Mountains in Colorado (CR) play a key role for the central and western South, but the Sierra Nevada and even the Appalachian Mountains are relevant, too. The temperature and precipitation based sc–PDSI is able to capture this link because increased soil moisture results in higher evapotranspiration with lower sensible heat and vice versa. A time shifted MCA indicates a prediction skill for drought conditions in spring and early summer for the downstream regions of CR on the basis of SWE in March. Furthermore, the phase of the El Niño–Southern Oscillation is a good predictor for drought in the southern US and SWE around Colorado. The influence of the North Atlantic Oscillation and Pacific North American Pattern is not that clear.
Technical note: Snow Water Equivalence Estimation (SWEE) Algorithm from
Snow Depth Time Series Using a Snow Density Model
Authors: Ohara Noriaki , He Siwei , Parsekian Andrew D. , Kelleners Thijs
Published: October 2018

Abstract. Snow water equivalence (SWE) is typically computed from snow weight by the SNOTEL system in the US. However, a snow pillow, the main snow weight sensor used by SNOTEL, requires a large, open, flat area (at least 9 square meters) and substantial maintenance costs. This article presents the snow water equivalence estimation (SWEE) algorithm that estimates the SWE evolution merely from continuous snow depth and temperature measurements using common sensors. The key component is a depth-averaged snow density model that is available in the literature, but is underutilized. Here, we demonstrate that the snow density model can estimate mass exchanges (SWE changes due to snowfall, erosion, deposition, and snowmelt) as well as the SWE. The SWEE algorithm can potentially increase the number of snow monitoring locations because snow depth and temperature sensors are considerably more accessible and economical than snow weighing sensor.
Contribution of Potential Evaporation Forecasts to 10-day streamflow forecast skill for the Rhine river
Authors: van Osnabrugge Bart , Uijlenhoet Remko , Weerts Albrecht
Published: October 2018

Abstract. Medium term hydrologic forecast uncertainty is strongly dependent on the forecast quality of meteorological variables. Of these variables, the influence of precipitation has been studied most widely, while temperature, radiative forcing and their derived product potential evapotranspiration (PET) have received little attention from the perspective of hydrological forecasting. This study aims to fill this gap by assessing the usability of potential evaporation forecasts for 10-day-ahead streamflow forecasting in the Rhine basin, Europe. In addition, the forecasts of the meteorological variables are compared with observations. Streamflow reforecasts were performed with the daily wflow_hbv model used in previous studies of the Rhine using the ECMWF 20-year meteorological reforecast dataset. Meteorological forecasts were compared with observed rainfall, temperature, global radiation and potential evaporation for 148 subbasins. Secondly, the effect of using PET climatology versus using observation-based estimates of PET was assessed for hydrological state and for streamflow forecast skill. We find that: (1) there is considerable skill in the ECMWF reforecasts to predict PET for all seasons, (2) using dynamical PET forcing based on observed temperature and satellite global radiation estimates results in lower evaporation and wetter initial states, but (3) the effect on forecasted 10-day streamflow is limited. Implications of this finding are that it is reasonable to use meteorological forecasts to forecast potential evaporation and use this is in medium-range streamflow forecasts. However, it can be concluded that an approach using PET climatology is also sufficient, most probably not only for the application shown here, but for most models similar to the HBV concept and for moderate climate zones. As a by-product, this research resulted in gridded datasets for temperature, radiation and potential evaporation based on the Makkink equation for the Rhine basin. The datasets have a spatial resolution of 1.2 × 1.2 km and an hourly timestep for the period from July 1996 through 2015. This dataset complements an earlier precipitation dataset for the same area, period and resolution.
Online model calibration for a simplified LES model in pursuit of real-time closed-loop wind farm control
Authors: Doekemeijer Bart M. , Boersma Sjoerd , Pao Lucy Y. , Knudsen Torben , van Wingerden Jan-Willem
Published: October 2018

Abstract. Wind farm control often relies on computationally inexpensive surrogate
models to predict the dynamics inside a farm. However, the reliability of
these models over the spectrum of wind farm operation remains questionable
due to the many uncertainties in the atmospheric conditions and
tough-to-model dynamics at a range of spatial and temporal scales relevant
for control. A closed-loop control framework is proposed in which a
simplified model is calibrated and used for optimization in real time. This
paper presents a joint state-parameter estimation solution with an ensemble
Kalman filter at its core, which calibrates the surrogate model to the actual
atmospheric conditions. The estimator is tested in high-fidelity simulations
of a nine-turbine wind farm. Exclusively using measurements of each turbine's generated power, the adaptability to modeling errors and mismatches in
atmospheric conditions is shown. Convergence is reached within 400 s of
operation, after which the estimation error in flow fields is negligible. At
a low computational cost of 1.2 s on an 8-core CPU, this algorithm shows
comparable accuracy to the state of the art from the literature while being
approximately 2 orders of magnitude faster.
The morphology of first-person object forms of directional verbs in ASL
Authors: Hou Lynn , Meier Richard P.
Published: October 2018

There is an ongoing debate about whether there exists a grammatical distinction between first-person and non-first person in signed languages, namely American Sign Language (ASL). The debate has been based largely on different analyses of pointing signs but minimally on the person-marking of directional verbs for object. We present an analysis of 95 unique first-person object forms of directional verbs from a combination of elicited and naturalistic data. We test the hypothesis that there is a default first-person object location at the center of the chest. Although we report evidence consistent with that hypothesis, we also find that some first-person verb forms are irregular with respect to the following dimensions of morphological properties in which they are lexically specified for: (1) final place of articulation; (2) height; (3) facing; and (4) body contact. Furthermore, a handful of directional verbs do not have first-person object forms. We interpret the findings to constitute evidence for the distinction between first-person and non-first person in ASL.
Locative Shift
Authors: Schlenker Philippe
Published: October 2018

In sign language, one may sometimes re-use a locus that originally referred to a spatial location in order to denote an individual found at that location (“Locative Shift”). We suggest that Locative Shift arises when a covert individual-denoting variable a is merged with a location-denoting locus b to form a complex expression ab, which denotes a situation stage of an individual. We investigate basic properties of Locative Shift in ASL: the phenomenon extends to temporal and modal shift; indexical loci are not usually locative-shifted; Locative Shift may have interpretive consequences, some of which appear to be at-issue; and Locative Shift can occur in highly iconic cases, possibly even without prior establishment of a situation-denoting locus. We further investigate the behavior of the co-opted loci under predicate ellipsis. The individual component of a locative-shifted locus can be bound, and in some cases its locative specification can be disregarded in the elided clause, under conditions that are reminiscent of the behavior of phi-features. In other cases, locative specifications are preserved under ellipsis, possibly even with elided indexical pronouns, whose overt counterparts resist Locative Shift. Some of our main findings can be replicated in LSF, although our data leave many questions open. Finally, we argue that some pointing gestures in English can undergo something like Locative Shift.

Published: October 2018

Na odontopediatria, o ambiente odontológico gera medo e ansiedade, demonstrados de diversas formas pela criança, de modo que há necessidade de promover sua adaptação para que entenda o processo e se sin­ta parte dele. É importante, ainda, que se identifiquem situações em que o desconforto estético possa gerar constrangimento na convivência diária das crianças. Objetivo: relatar um caso clínico de resolução de com­prometimento estético causado por defeito de desenvol­vimento do esmalte (DDE) e utilização de técnicas de adaptação de comportamento. Relato de caso: uma pa­ciente do sexo feminino, 3 anos de idade, nascida pre­matura, apresentava DDE no incisivo central superior esquerdo, que, ao sorrir, cobria com as mãos. O perfil da criança foi avaliado e, a partir das suas característi­cas, foram escolhidas as técnicas de dizer-mostrar-fazer, controle de voz, reforço positivo, distração e repetição, usando-as de forma associada para melhores resulta­dos, considerando a necessidade da repetição das vi­sitas ao consultório. Após cinco consultas, foi possível realizar a restauração com resina fotopolimerizável, restabelecendo a estética e o conforto para a criança. Considerações finais: para o atendimento odontológico de crianças, é de fundamental importância conhecer técnicas de manejo infantil e usá-las de acordo com as necessidades individuais, com a finalidade de tornar as crianças participativas no processo, diminuindo a an­siedade, o medo e as reações que podem dificultar ou impedir o atendimento.

Introdução: pacientes acometidos por traumatismo craniofacial podem evoluir com sequelas variadas. Objetivo: identificar a prevalência de sequelas neuro­lógicas ocorridas entre os pacientes com traumatismo craniofacial em um serviço de referência para o trauma no sul do Brasil. Sujeitos e método: foram analisados 1.385 prontuários, em que 169 (12%) pacientes foram selecionados com trauma em crânio e face simultane­amente, levando em consideração o agente etiológico, a procedência, a idade, o sexo do paciente e a locali­zação das fraturas. Resultados: uma taxa de 85% dos indivíduos era do sexo masculino, com faixa etária en­tre 31-40 anos. Os fatores etiológicos mais prevalen­tes foram acidentes de trânsito (36%), quedas (22%) e violência interpessoal (21%). No grupo selecionado, o traumatismo cranioencefálico esteve presente em 89% dos casos; em 64% da população, não houve sequela neurológica; 28% apresentaram algum tipo de seque­la; e em 8% dos prontuários não havia informações completas. Conclusão: na população estudada, mesmo com um subgrupo específico de traumatizados, houve prevalência de gênero masculino, terceira década de vida e acidente automobilístico. Além disso, a região anatômica mais acometida foi o conjunto de ossos do terço médio da face, e, ainda nesta condição de asso­ciação, o traumatismo cranioencefálico esteve presente na maioria dos casos, porém, somente 28% dos casos evoluíram com alguma sequela neurológica.

O trabalho teve como objetivo avaliar o efeito do uso de hipoclorito de cálcio (Ca(OCl)2) como irrigante na resistência de adesão do cimento AH Plus (De Trey-Dentsply, Konstanz, Alemanha) à dentina pelo teste de micro push-out. Trinta e três dentes humanos monorradiculares foram seccionados transversalmente na junção amelocementária e divididos em três grupos: hipoclorito de sódio (NaOCl) 2,5%, hipoclorito de cálcio 2,5% e soro fisiológico. Os canais foram preparados, irrigados ao final com EDTA 17% e foram obturados com cones de guta percha e cimento AH Plus. Após armazenagem por sete dias em 100% de umidade a 37°C, os dentes foram seccionados transversalmente ao longo eixo da raiz. Foram obtidas 3 fatias de cada dente (n=33), que foram submetidas ao ensaio de push-out. O tipo de falha foi analisado por fractografia, e classificado em falha adesiva, coesiva ou mista. Os valores de resistência de união foram analisados pelo teste de Kruskal-Wallis com nível de significância de 95%. O grupo Ca(OCl)2 2,5% apresentou a menor média de resistência de adesão, diferindo estatisticamente do NaOCl e soro fisiológico (p<0,05). Não houve diferença estatística entre os grupos irrigados com soro e NaOCl (p>0,05). A falha predominante em todos os grupos foi a do tipo adesiva. O Ca(OCl)2 2,5% teve um efeito negativo sobre a força de adesão do AH Plus à dentina radicular quando comparado ao NaOCl 2,5%.

Em um momento em que o Brasil ingressa na rota de novos fluxos migratórios em Em um momento em que o Brasil ingressa na rota de novos fluxos migratórios em decorrência das consequências da globalização que, para muitos, apresenta-se em sua versão perversa (SANTOS, 2001), faz-se necessário investigar como os migrantes vivenciam as políticas públicas voltadas para seu acolhimento e inserção social no país. O presente artigo objetiva, a partir das narrativas de dois migrantes residentes no município de São Paulo, analisar como mecanismos de regulamentação de entrada e permanência no país e políticas de acolhimento disponíveis são vivenciados por eles e, partindo dessas reflexões, levantar algumas implicações sobre políticas de acolhimento. As narrativas foram geradas por meio de conversas informais áudio-gravadas com o objetivo de relatar a experiência vivida pelos migrantes em relação à acolhida e às possibilidades de inserção social no país. As análises das narrativas mostram que, apesar dos avanços legislativos e de ações institucionais voltadas ao acolhimento e inserção social, ainda fazem falta medidas que viabilizem a concessão de vistos de entrada, a permissão ao vínculo empregatício, bem como políticas de línguas para ampliar o acesso à informação e auxiliar no processo de (re)reterritorialização (HAESBAERT, 2004; BIZON, 2013).

VOZES DO PROGRAMA EMERGENCIAL PRÓ-HAITI: NARRATIVAS DE RACIALIZAÇÃO DO “SER HAITIANO”
Authors: Bizon Ana Cecília Cossi , Dangió Gabriel Vinícius
Published: October 2018

O presente artigo tem como objetivo refletir sobre o processo de inserção de estudantes estrangeiros provenientes de países periféricos (WALLERSTEIN, 1974), no caso haitianos, no ambiente universitário brasileiro. Para tanto, como dados primários, são focalizados excertos de narrativas de dois estudantes do Programa Emergencial em Educação Superior Pró-Haiti, em uma universidade pública brasileira, geradas a partir de conversas informais audiogravadas. Tais narrativas topicalizam os sentidos produzidos pelas experiências de reterritorialização (HAESBAERT, 2004; BIZON, 2013) desses jovens ao longo de sua estadia no Brasil.  Além disso, como dados secundários, considera-se um excerto de narrativa de uma jovem estadunidense negra participante de um programa de mobilidade em uma universidade federal brasileira. Acreditamos que a análise das narrativas dos estudantes haitianos na interface com a narrativa da jovem estadunidense seja potencialmente capaz de lançar luzes sobre particularidades dos processos de (re)territorialização de estrangeiros oriundos de países não centrais. A análise dos dados indica que processos de racialização (SILVERSTEIN, 2005; BUTLER, 2004; GALABUZI, 2006; BIZON & CAVALCANTI, 2018) experienciados pelos estudantes haitianos incidem fortemente em suas (re)territorializações. O imaginário socialmente articulado do que é ser haitiano, negro, estrangeiro, dentre outras identificações, é mobilizado nas relações que esses estudantes estabelecem nas diferentes práticas sociais nas quais se engajam, gerando percepções de discriminação e exclusão. Espera-se, com a visibilização dessas narrativas (WORTHAM, 2001; THREADGOLD, 2005; BAYNHAM & DE FINA, 2017), contribuir para a discussão de políticas de inserção no contexto de internacionalização de nossas universidades, as quais ainda privilegiam o diálogo com países centrais e atores hegemônicos.
Updates on and Controversies Related to Management of Radial Nerve Injuries

Radial nerve injuries are among the most common major traumatic peripheral nerve injuries. Recent literature has updated our knowledge of aspects ranging from radial nerve anatomy to treatment options. Observation and tendon transfers were, and still are, the mainstays of management. However, the improved outcomes of nerve repair even 5 months after injury have changed the treatment algorithm. Nerve repair techniques using conduits, wraps, autograft, and allograft allow tension-free coaptations to improve success. Nerve transfers have evolved to allow a more anatomic recovery of function if used in a timely manner. This review offers an update on radial nerve injuries that reflects recent advances.

Objectives: The seasonality in the diagnosis of acute leukemias(ALs) has been conceived ever since and the results have beenconfounding between summer and winter peaks since those times.To our knowledge, the seasonality in the diagnosis ALs has notbeen explored in our region and we aimed to investigate for aseasonal accumulation in the diagnosis of AL patients.Materials and Methods: A hundred and sixty-two patientswho were diagnosed with either acute myeloid leukemia (AML)or acute lymphocytic leukemia (ALL) between November 2012and October 2017 were included in the study. The data regardingthe gender, age, type of leukemia and the time of admission werenoted from files of the patients.Results: The median age of the patients was 51.5 years (range,17-85) with 64 (39.5%) female, 98 (60.5%) male. Most of ALpatients were diagnosed in August (21,13%) and the least in Junewith 6 (3.7%) patients. According to the seasons; 39 (24.1%)patients were diagnosed in winter, 40 (24.7%) patients in spring,40 (24.7%) patients in summer and 43 (26.5%) patients in autumn(P>0.05).Conclusion: We could not determine any seasonality in thediagnosis of ALs, both AML and ALL, in our study.

Objectives: A detailed knowledge about the anatomy of thefemoropatellar groove (FPG) and its articulation is essential for thebetter understanding of the patellar stability. Therefore, the presentstudy was carried out to describe the morphology of FPG in adultsand the pattern of its growth in fetuses.Materials and Methods: Thirty-seven adult dry femora ofunknown age and 24 fetal femora of known gestational age wereincluded in the study. The dimensions of FPG and its angulationswere calculated digitally using Image J software and were analyzedstatistically.Results: The femoropatellar angulation ranged from 136.38°to 142.38°. The dimensions and angulation were correlated withthe gestational age. The dimensions of FPG and the altitude oflower end of the femur increased significantly with the gestationalage (P<0.05). There was also a significant negative correlationbetween the femoropatellar angulation and the gestational age(P<0.05).Conclusion: This study provides a database for the parametersof the adult femora. It also describes the pattern of growth ofthe lower end of fetal femur. These findings are essential indetermining the patellar stability during walking.

Spontaneous intraabdominal hemorrhage is a very rare event even in patients with bleeding disorders like hemophilia. Nevertheless this rare case must be considered in patients with coagulopathies presenting with abdominal pain. Prompt radiologic imaging and surgical consultation are of highest priority. Here we report on a 20-year-old patient with moderate hemophilia A, who underwent emergency laparotomy for a spontaneous idiopathic bleeding of the omentum majus. There are few cases in the literature on this sort of event in patients with hemophilia, who mostly suffer from spontaneous joint bleedings. These patients require an intensive, interdisciplinary perioperative care, involving haematologists, surgeons, radiologists and anesthesists. Finally we discuss, whether an optimized, individually adapted treatment with coagulation factors might possibly have prevented this bleeding event in this patient.

Published: October 2018

Idarucizumab is designed to reverse the anticoagulant effect of dabigatran. This case report describes the administration of three independent doses of idarucizumab to a 76-year-old man suffering from atrial flutter being treated with dabigatran to prevent ischaemic stroke. The last dose of dabigatran was administered in the morning of the same day the patient was transferred to hospital because of the need for urgent pericardium puncture. Baseline dTT (dilute thrombin time) reached 700 ng/mL as glomerular filtration (GF) dropped to 0.19 mL/s. The first dose of idarucizumab was administered prior to puncture and the clinical state was stabilized for the next 24 hours although dTT climbed to 400 ng/mL. The need for cannulation before dialysis required a second dose of antidote and a third dose was given prior to removal of the pericardium drain. Monitoring of dabigatran recovery showed that the reverse effect of idarucizumab lasted 12 hours, which is sufficiently long and reliable for urgent situations. Idarucizumab administration is not limited by age and/or renal impairment. We recommend repeated dTT examinations when the dabigatran baseline level exceeds 200 ng/mL and the antidote has been administered.

Published: October 2018

Expulsion from school is a life changing event and can leave a big scar in students’ lives making them feel lost or miserable. This incident might change the direction of a student’s life and whether the outcome is good or bad, will largely depend on the student. However, without keen intercession especially from parents, this interference in the students' lives might have an unsalvageable effect. This narrative case study aims to find out about an expelled girl’s life once she left her old school where she was expelled from. The intention of this study is to understand how the respondent recognizes and overcomes her negative perception and emotions as an expelled student in the new school in regards to her psychosocial development. Results from the findings using qualitative interviewing, journal writing, and document analysis show four notable areas. The expelled student (1) expresses deep feeling of contrition after expulsion, (2) managed her emotions by surrounding herself in the company of people who gave her moral support like her parents, teachers and friends (3) parents, particularly mother, was the most pivotal in helping through her emotions, (4) feels the expulsion was unfair, but supports zero tolerance policies for serious offenses. This research provides valuable information regarding the expulsion experience of a student and addresses the effect on the student’s psychosocial development. The analysis concludes that expulsion can be coped by the student with proper guidance and leads the expulsion experience in a positive way.

The construction, development and maintenance of an economically, environmentally and socially sustainable campus involves the integration of measuring tools and technical information that invites and encourages the community to know the actual state to generate positive actions for reducing the negative impacts over the local environment. At the Universidad Nacional de Colombia - Campus Bogotá, a public area with daily traffic of more than 25000 people, the Environmental Management Bureau has committed with the monitoring of the noise pollution and air quality, as support to the campaigns aiming to reduce the pollutant emissions associated to the student’s activities and campus operation. The target of this study is based in the implementation of mobile air quality and sonometry monitoring equipment, the mapping of the actual air quality and noise pollution inside the university campus as a novel methodology for a sub-area inside a megacity. This results and mapping are proposed as planning tool for the institution administrative sections. A mobile Kunak® Air & OPC air monitoring station with the capability to measure particulate matter PM10, PM25, Ozone (O3), Sulfur Oxide (SO2), Carbon Monoxide (CO) and Nitrogen Oxide (NO2) as well as Temperature, Relative Humidity and Latitude and Longitude coordinates for the data georeferenciation; and a sonometer Cirrus® 162B Class 2 were used to perform the measurements. The measurements took place in conditions of academic activity and without it, with the aim of identify the impacts generated by the campus operation. Using the free code geographical information software QGIS® 2.18, the maps of each variable measured were developed, and the impacts generated by the operation of the campus were identified qualitative and quantitively. For the measured variables, an increase of around 21% for the LAeq noise level and around 80% to 90% for air pollution were detected during the operation period.
