Authors: Cacko Andrzej , Kozyra-Pydyś Eliza , Gawałko Monika , Opolski Grzegorz , Grabowski Marcin
Published: December 2018

Introduction:

Venous stenosis or occlusion related to an intracardiac device is a well-known complication of that procedure. There are numerous studies tried to determine predictors of venous stenosis or occlusion; however, most of them investigate the venous system prior to device upgrade, generator replacement, or transvenous lead extraction. Therefore, we aimed to assess the prevalence and determine the predictors of venous stenosis or occlusion following first transevnous cardiac device implantation.

Methods:

Observational, prospective study included 71 consecutive patients admitted for first transvenous cardiac device implantation. All patients were followed up for 6 months after operation.

Results:

Implanted device systems comprised cardioverter defibrillator (n = 26), single-chamber or dual-chamber pacemakers (n = 34), and biventricular pacemakers (n = 11); 88.5% of implantable cardioverter defibrillator leads were single-coils and 11.5% were dual-coils. The incidence of venous stenosis or occlusion within 6-month follow-up was 21.1%. Multivariate logistic regression showed that only diabetes or prediabetes (p = 0.033, odds ratio: 0.17, 95% confidence interval: 0.04–0.87), prolonged procedure time (p = 0.046, odds ratio: 4.54, 95% confidence interval: 1.01–20.12), and perioperative complications (p = 0.021, odds ratio: 7.04, 95% confidence interval: 1.35–36.85) were predictors of venous stenosis or occlusion.

Conclusion:

Prolonged implantation time (>60 min) and perioperative complications are associated with an increased risk of venous stenosis or occlusion, whereas diabetes and prediabetes significantly reduce the risk of venous stenosis or occlusion.
Flexure–shear interaction in hybrid steel I-girders at ambient and elevated temperatures
Authors: Ghadami Abbas , Broujerdian Vahid
Published: December 2018

In literature, there is no theoretical research focusing on moment–shear interaction behavior of the hybrid girders. This article investigates the moment–shear interaction behavior of non-composite hybrid steel plate I-girders at ambient and elevated temperatures. In this regard, based on a more realistic distribution of bending and shear stresses, theoretical equations have been proposed to achieve the moment–shear interaction curve without considering shear buckling. The results obtained from the proposed equations were compared with the results of the existing experimental data and those of the finite element analysis. According to the results, there is good agreement between them.
Art tourism: A new field for tourist studies
Authors: Franklin Adrian
Published: December 2018

This article argues the case for art tourism as a new field of tourist studies. At present, art tourism is currently obscured under cultural tourism’s voluminous bounds – which are as inappropriate as they are unwieldy and overloaded. More specifically, it cannot adequately contain art tourism’s distinctive origins, forms of experience and articulation between art worlds, cities and regions and tourism industries. In part, a more dedicated research field is also needed to keep track of its rapid growth and development as a primary driver of regional and urban regeneration and for the much expanded exhibitionary complex it encompasses. As a place-changing vehicle for city life, art tourism also needs separate forms of data collection to assist in its effective planning and design. Museums that have historically catered for local art publics now need to relate increasingly to growing touring art publics. The article sets out the historical and contemporary significance of art tourism in order to identify the breadth of a new tourism agenda, as well as its connections to other disciplines including art, architecture, social anthropology, cultural economy, urban studies, museology, aesthetics and the sociology and geography of art.
Component-based regularization of a multivariate GLM with a thematic partitioning of the explanatory variables
Authors: Bry Xavier , Trottier Catherine , Mortier Frédéric , Cornu Guillaume
Published: December 2018

We address component-based regularization of a multivariate generalized linear model (GLM). A vector of random responses [Formula: see text] is assumed to depend, through a GLM, on a set [Formula: see text] of explanatory variables, as well as on a set [Formula: see text] of additional covariates. [Formula: see text] is partitioned into [Formula: see text] conceptually homogenous variable groups [Formula: see text], viewed as explanatory themes. Variables in each [Formula: see text] are assumed many and redundant. Thus, generalized linear regression demands dimension reduction and regularization with respect to each [Formula: see text]. By contrast, variables in [Formula: see text] are assumed few and selected so as to demand no regularization. Regularization is performed searching each [Formula: see text] for an appropriate number of orthogonal components that both contribute to model [Formula: see text] and capture relevant structural information in [Formula: see text]. To estimate a single-theme model, we first propose an enhanced version of Supervised Component Generalized Linear Regression (SCGLR), based on a flexible measure of structural relevance of components, and able to deal with mixed-type explanatory variables. Then, to estimate the multiple-theme model, we develop an algorithm encapsulating this enhanced SCGLR: THEME-SCGLR. The method is tested on simulated data and then applied to rainforest data in order to model the abundance of tree species.

Authors: Corona-Meraz Fernanda-Isadora , Vázquez-Del Mercado Mónica , Ortega Francisco José , Ruiz-Quezada Sandra-Luz , Guzmán-Ornelas Milton-Omar , Navarro-Hernández Rosa-Elena
Published: December 2018

Objective:

The identification of circulating microRNAs related to abnormal metabolic function may be useful in the context of ageing, adiposity and insulin resistance. The miR-33 a/b has been shown to control the expression of genes involved in fatty acid biosynthesis, impaired metabolism and insulin resistance. In this study, we aimed to identify differences in circulating miR-33 a/b levels according to age-related metabolic impairment and increased adiposity.

Methods:

This study included 80 individuals (30.2% with obesity, 70% females) classified according to insulin resistance (Stern’s criteria) and age [young (20–39 years) and senior (40–59 years)]. Body fat was evaluated using bioelectrical impedance, biochemical markers by colorimetric, enzymatic and immuno-turbidimetry methods. TaqMan measures of circulating miR-33 a and miR-33 b with quantitative reverse transcription polymerase chain reaction in serum were assessed in association with clinical outputs.

Results:

Circulating miR-33 a and miR-33 b levels showed significant association with fatness, the lipid profile and biomarkers of impaired glucose metabolism. Both miR-33 a and miR-33 b were associated with visceral adiposity index in non-insulin resistance and insulin resistance individuals. More important, for miR-33 a circulating levels in senior group, receiver operating characteristic curve analyses showed area under the curve 0.804 ( p = 0.010; 95% confidence interval = 0.655–0.952).

Conclusion:

Ageing influenced the relationship of circulating miR-33 a and miR-33 b with insulin resistance and increased adiposity.
Predicting remaining useful life of rolling bearings based on deep feature representation and long short-term memory neural network
Authors: Mao Wentao , He Jianliang , Tang Jiamei , Li Yuan
Published: December 2018

For bearing remaining useful life prediction problem, the traditional machine-learning-based methods are generally short of feature representation ability and incapable of adaptive feature extraction. Although deep-learning-based remaining useful life prediction methods proposed in recent years can effectively extract discriminative features for bearing fault, these methods tend to less consider temporal information of fault degradation process. To solve this problem, a new remaining useful life prediction approach based on deep feature representation and long short-term memory neural network is proposed in this article. First, a new criterion, named support vector data normalized correlation coefficient, is proposed to automatically divide the whole bearing life as normal state and fast degradation state. Second, deep features of bearing fault with good representation ability can be obtained from convolutional neural network by means of the marginal spectrum in Hilbert–Huang transform of raw vibration signals and health state label. Finally, by considering the temporal information of degradation process, these features are fed into a long short-term memory neural network to construct a remaining useful life prediction model. Experiments are conducted on bearing data sets of IEEE PHM Challenge 2012. The results show the significance of performance improvement of the proposed method in terms of predictive accuracy and numerical stability.

Authors: Lim Rebecca , Lee Ellen , Lim Joel , Chong Alphonsus K. S. , Sebastin Sandeep J. , Foo Anthony
Published: December 2018

Venous congestion in distal digital replantations is a common problem as suitable veins are not always available. We compared two methods of venous decongestion, external bleeding ( n = 15) and dermal pocketing ( n = 28) carried out when venous anastomosis was not possible. The findings of this small study suggest that neither method of venous decongestion is clearly better than the other.

What does a firm maximize? A simple explanation with regard to economic growth
Authors: Mert Merter
Published: December 2018

The purpose of this study is to explain the following proposition: Profit maximization objective is only an assumption, which is valid only when marginal cost is zero; a firm should maximize its total sales rather than its profit when marginal cost is not equal to zero. Using simple logical consequences, the study shows the following: (i) Cournot equilibrium occurs at total revenue maximization conditions rather than profit maximization conditions, even if costs are not neglected; (ii) if average costs of plants are not equal to each other, a multiple-plant monopoly cannot maximize its profit; it should maximize its total revenue, even if costs are not zero; (iii) a firm’s goal should be total revenue maximization rather than profit maximization, when marginal cost is not equal to zero; (iv) profit maximization behaviour does not have to explain economic growth; however, total sales maximization behaviour clearly explains economic growth and (v) total sales maximization objective, at the producer’s equilibrium conditions, guarantees stability under diminishing returns. The study concludes with nine simple results in order to support its claim. The results of the study emphasize that (i) an empirical analysis based on a strict theory should start to the analysis depending on a goal function which maximizes total sales rather than profit and (ii) a representative social planner who designs a growing economy, which grows thanks to total sales maximization behaviour of firms, should design the economy where price changes do not give advantage to the firms.

Published: December 2018

Ischemia–reperfusion is defined as cellular damage after the reperfusion of ischemic tissue, and it is likely to occur in relation to various diseases and surgical procedures. The purpose of this study was to evaluate the capability of atorvastatin to prevent oxidative damage and modulate the release of proinflammatory cytokines in rat hindlimb during ischemia–reperfusion injury. The animals were divided into 4 groups (ischemia–reperfusion + vehicle, ischemia–reperfusion + atorvastatin, sham, and healthy controls) with 15 rats per group. The animals were exposed to ischemia for 6 h, followed by 24 h, 7 days, and 14 days of reperfusion. Atorvastatin was administered by gavage 14 days before ischemia–reperfusion induction. We then measured the serum concentrations and mRNA transcript levels of TNF-α, IL-1β, IL-6, IL-10, SOD2, and CAT. Hematoxylin and eosin stain were performed for histological analyses. Animals subjected to ischemia–reperfusion showed increased serum and transcript levels of TNF-α, IL-1β, IL-6, and IL-10 expressions with a concurrent increase in mRNA transcripts levels compared with sham and healthy controls. Groups treated with atorvastatin showed a significant CAT increase in the first 24 h, but CAT levels decreased at 7 and 14 days. SOD2 enzyme increased in serum without significant changes in mRNA expression. Histological analysis showed inflammatory infiltrate, microhemorrhages, and distortion of the tissue architecture in the first 7 days. At 14 days, the tissue showed loss and damage to myocytes. However, animals treated with atorvastatin showed few histological changes and a decrease in inflammatory cytokines. No significant changes in NO2, NO3, or 8-OHdG were observed. Atorvastatin showed a protective effect on the inflammation and tissue damage induced by ischemia–reperfusion in the hindlimb. The antioxidant effect of atorvastatin in the hindlimb is already unclear, and further research is needed to elucidate the molecular mechanism of this drug in the extremities.
Athletes With Musculoskeletal Injuries Identified at the NFL Scouting Combine and Prediction of Outcomes in the NFL: A Systematic Review
Authors: Wang Dean , Weiss Leigh J. , Abrams Madeline , Barnes Ronnie P. , Warren Russell F. , Rodeo Scott A. , Taylor Samuel A.
Published: December 2018

Background:

Prior to the annual National Football League (NFL) Draft, the top college football prospects are evaluated by medical personnel from each team at the NFL Scouting Combine. On the basis of these evaluations, each athlete is assigned an orthopaedic grade from the medical staff of each club, which aims to predict the impact of an athlete’s injury history on his ability to participate in the NFL.

Purpose:

(1) To identify clinical predictors of signs, symptoms, and subsequent professional participation associated with football-related injuries identified at the NFL Combine and (2) to assess the methodological quality of the evidence currently published.

Study Design:

Systematic review; Level of evidence, 3.

Methods:

A systematic review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We reviewed all studies that examined musculoskeletal injuries identified among athletes at the NFL Combine and associated outcomes. Data on signs, symptoms, and subsequent NFL participation were collected, and the methodological quality of the studies was assessed.

Results:

Overall, 32 studies, including 30 injury-specific studies, met the inclusion criteria. Twenty studies analyzed data collected at the NFL Combine from 2009 and later. When compared with matched controls, athletes with a history of a cervical or lumbar spine injury, rotator cuff repair, superior labrum anterior-posterior repair, anterior cruciate ligament reconstruction, full-thickness chondral lesions of the knee, or Lisfranc injury played in significantly fewer games early in their NFL careers. Additionally, athletes with a history of a cervical or lumbar spine injury, rotator cuff repair, and navicular injury had decreased career lengths versus controls. Defensive players and linemen were found to have decreased participation in the NFL for several injuries, including prior meniscectomy, anterior cruciate ligament reconstruction, and shoulder instability. Career length follow-up, measures of athletic participation, and matching criteria were highly variable among studies.

Conclusion:

For medical professionals caring for professional football athletes, this information can help guide orthopaedic grading of prospects at the NFL Combine and counseling of athletes on the potential impact of prior injuries on their professional careers. For future studies, improvements in study methodology will provide greater insight into the efficacy of current treatments and areas that require further understanding.
Reverse time migrations in transversely isotropic media: A comparison between acoustic and elastic wave equations with two wave mode separation algorithms
Authors: Wang Wenlong , Hua Biaolong , McMechan George A. , Williamson Paul
Published: December 2018

Anisotropic reverse time migrations (RTMs) using pseudoacoustic or elastic wave equations are tested, and the migrated PP images, obtained using the same data set as input, are compared. In anisotropic elastic RTMs, both divergence operators, and localized low-rank approximations (LLA), are tested and compared for P/S separation. Tests with synthetic data indicate that elastic RTMs have better illumination apertures than pseudoacoustic RTMs in subsalt areas because of the involvement of converted S-waves in the former. Pseudoacoustic RTMs have diamond-shaped S-wave artifacts, which do not exist in elastic RTM images, provided that the P- and S-waves are separated in the elastic wavefields. LLAs provide affordable, accurate P/S separations in anisotropic media, and the separation results are better than those obtained using divergence operators. Anisotropic elastic RTMs with LLA give the best quality images.
Stimuli-Responsive Molecular and Macromolecular Systems Controlled by Rotaxane Molecular Switches
Authors: Takata Toshikazu
Published: December 2018

Synthesis and dynamic nature of molecular and macromolecular systems controlled by rotaxane molecular switches are discussed. Rotaxane molecular and macromolecular switches including those working without solvent were synthesized mainly using sec-ammonium salt/crown ether couples. A linear polymer possessing a crown ether/sec-ammonium salt-type [1]rotaxane moiety at the chain terminal was prepared by the rotaxane-linking of single polymer chain, and applied to the linear polymer–cyclic polymer topology transformation. Successful synthesis of macromolecular [2]rotaxane (M2R) possessing single polymer axle and one crown ether wheel made possible a variety of unique applications such as development of topology-transformable polymers and rotaxane cross-linked polymers (RCPs) by connecting polymer chains to the components of M2R. The pronounced dynamic nature of these polymer systems is quite interesting and is expected to afford much useful information for designing novel stimuli-responsive molecules, polymers, and polymer materials.
Skewed Wealth Distributions: Theory and Empirics
Authors: Benhabib Jess , Bisin Alberto
Published: December 2018

Invariably, across a cross-section of countries and time periods, wealth distributions are skewed to the right displaying thick upper tails, that is, large and slowly declining top wealth shares. In this survey, we categorize the theoretical studies on the distribution of wealth in terms of the underlying economic mechanisms generating skewness and thick tails. Further, we show how these mechanisms can be micro-founded by the consumption–savings decisions of rational agents in specific economic and demographic environments. Finally we map the large empirical work on the wealth distribution to its theoretical underpinnings. (JEL C46, D14, D31, E21, J31)

The Sound of Silence: A Review Essay of Nancy MacLean’s Democracy in Chains: The Deep History of the Radical Right’s Stealth Plan for America
Authors: Fleury Jean-Baptiste , Marciano Alain
Published: December 2018

This essay reviews Nancy MacLean’s Democracy in Chains: The Deep History of the Radical Right’s Stealth Plan for America, which triggered a huge controversy that virally spread on the Internet and in various journals. We will evaluate MacLean’s almost biographical account of James Buchanan, which portrays the 1986 Nobel Prize laureate as the mastermind behind today’s attacks, by the foot soldiers of the radical right, on American democracy. This essay develops three main points. One, MacLean’s general narrative puts too much emphasis on Buchanan and largely neglects the many other important characters who contributed to the intellectual criticism of government intervention. Two, MacLean’s account is marred by many misunderstandings about public choice theory, for instance about the role that simple majority rule plays in constitutional economics. Third, in the midst of abundant archival material, her historical narrative is, at best, sketchy, and is replete with significantly flawed arguments, misplaced citations, and dubious conjectures. Overall, MacLean tends to overinterpret certain aspects in Buchanan’s life and thought, while she overlooks others that are equally important in understanding his work and influence. In particular, we stress that Buchanan was, first and foremost, a scholar, not a political activist, who gave significant attention to ethical considerations in his analysis of markets.

Tem gente que quer empreender, mas falta uma boa sacada. Ariel Lambrecht, sócio da Yellow Bike, ao contrário, tem tantas ideias que mal consegue dormir. Ainda na faculdade, quando cursava Engenharia Mecatrônica na Escola Politécnica da Universidade de São Paulo (USP), criou com o colega Renato Freitas o Ebah, uma rede social para alunos e professores compartilharem materiais de estudo. O negócio ganhou um prêmio de empreendedorismo na Poli e bombou.Depois de se formar, Ariel trabalhou por quatro anos no Google na Irlanda e aproveitou o que aprendeu para montar uma consultoria e ajudar as empresas a melhorar seu posicionamento no site de busca. Foi durante viagens que vieram as ideias para os seus negócios mais conhecidos, a 99 (criada com Renato e Paulo Veras) e a Yellow Bike (com Renato e Eduardo Musa). No primeiro caso, precisava pegar um táxi na Alemanha quando soube que existia um aplicativo para isso. No segundo, viajava para a China para negociar a venda da 99 quando conheceu empresas com um modelo de compartilhamento de bicicletas sem estações físicas.Em seu cérebro, que não desliga, surgem inúmeras formas de expandir a Yellow, que iniciou suas atividades neste ano em São Paulo. Bicicletas elétricas, patinetes na versão sentada... Várias alternativas de mobilidade estão sendo estudadas. Unir ao transporte soluções para pagamentos e alimentação, por que não? Um usuário da Yellow poderia usar a carteira virtual do aplicativo para pagar o metrô. Depois de sair da estação e pegar a bicicleta, pararia no caminho do escritório para pegar uma entrega de comida. “Acho que dá para fazer com que todo esse sistema converse”, diz Ariel.Nesta entrevista à GV-executivo, o empreendedor mostra como, além daquele clique, é preciso muito mais para um negócio vingar, como foco no usuário, conservadorismo na expansão e perseverança para enfrentar as incertezas e os reveses. “Se você está empreendendo só porque viu que a 99 deu muito certo e virou um unicórnio, não vai funcionar”, avisa.

Background: Individuals living in malaria-endemic regions develop naturally acquired immunity against severe malarial disease, but it is unclear whether immunity that affects the establishment of infections develops following continuous natural exposure.

Methods: We cleared schoolchildren in Burkina Faso of possible sub-patent infections and examined them weekly for incident infections by PCR. Plasma samples collected at enrolment were used to quantify antibodies to the pre-eryhrocytic-stage antigens circumsporozoite protein (CSP) and liver stage antigen. Sporozoite gliding inhibition by naturally acquired antibodies was assessed using Plasmodium falciparum NF54 sporozoites; hepatocyte invasion was assessed using the human HC-04 hepatoma cell line and NF54 sporozoites. The associations between these functional pre-erythrocytic immunity phenotypes and time to PCR-detected infection were studied.

Results: A total of 51 children were monitored; the median time to first detection of infection by PCR or development of clinical symptoms was 28 days. Anti-CSP antibody titres showed a strong positive association with sporozoite gliding motility inhibition (P<0.0001, Spearman’s ρ=0.76). In vitro hepatocyte invasion was inhibited by naturally acquired antibodies (median invasion inhibition, 19.4% [IQR 15.2-40.9%]), and there was a positive correlation between gliding and invasion inhibition (P=0.02, Spearman’s ρ=0.60). Survival analysis indicated longer time to infection in individuals displaying higher-than-median sporozoite gliding inhibition activity (P=0.01).

Conclusions: In summary, functional antibodies against the pre-erythrocytic stages of malaria infection are acquired in children who are repeatedly exposed to Plasmodium parasites. This immune response does not prevent them from becoming infected during a malaria transmission season, but might delay the appearance of blood stage parasitaemia and consequently needs to be considered in the evaluation of malaria vaccines.

Cel pracy

Celem pracy była analiza występowania czynników ryzyka chorób sercowo-naczyniowych (wiek, płeć, status palenia tytoniu, poziom stężenia cholesterolu i wysokość skurczowego ciśnienia tętniczego, wskaźnik masy ciała) wśród pacjentów z rozpoznaniem schizofrenii oraz poszukiwanie zależności pomiędzy nimi a długością pobytu w jednostce opieki długoterminowej, zmiennymi klinicznymi takimi jak: nasilenie objawów pozytywnych, negatywnych i ogólnych schizofrenii, czas trwania choroby oraz zastosowane leczenie (rodzaj neuroleptyku i jego dawka).

Metoda

Dane uzyskano z dokumentacji medycznej 71 pacjentów (30 kobiet i 42 mężczyzn) w wieku od 40 do 86 lat, przebywających w zakładzie opiekuńczo-leczniczym i leczonych z powodu schizofrenii paranoidalnej. Informacje dotyczące stanu klinicznego zostały zgromadzone podczas badania okresowego pacjentów. Badanie składało się z wywiadu od chorego, dotyczącego jego ogólnego samopoczucia, badania psychiatrycznego z użyciem skali PANSS oraz określenia liczby wypalanych przez pacjenta papierosów. W ocenie stanu somatycznego zawarto: badanie fizykalne, pomiar -ciśnienia tętniczego, tętna, poziomu glikemii we krwi włośniczkowej, wzrostu, masy ciała oraz wskaźnik BMI.

Wyniki

Nie wykazano istotnych różnic w długości pobytu w psychiatrycznym zakładzie opiekuńczo-leczniczym pomiędzy pacjentami z prawidłowym i nieprawidłowym (nadwaga i otyłość) wskaźnikiem BMI. U osób, które dłużej przebywały w psychiatrycznym zakładzie opiekuńczo-leczniczym częściej występowała otyłość brzuszna, nadciśnienie tętnicze, nieprawidłowy poziom cholesterolu całkowitego i LDL.

Wnioski

U 74,6% osób leczonych z powodu schizofrenii wykazano obecność co najmniej jednego czynnika ryzyka sercowo-naczyniowego. Narzucenie „zdrowego” stylu życia w trakcie pobytu w jednostce opieki długoterminowej może redukować ryzyko wzrostu masy ciała u osób poddanych farmakoterapii neuroleptykami (atypowymi i typowymi). Wysoce rekomendowane jest podejmowanie aktywnych działań zmniejszających modyfikowalne czynniki ryzyka sercowo-naczyniowego, także w opiece długoterminowej.

Published: December 2018

In this present work, the TiAlVN coatings were deposited by magnetron sputtering using a single alloy target of Ti60Al30V10. The effect of the argon (Ar) to nitrogen (N2) gas flow ratio on the structure, morphological characteristics and mechanical properties of the TiAlVN coating were investigated. The results of X-ray diffraction show the coatings have only face-centred cubic (fcc) structures at different gas ratio of Ar:N2. FE-SEM observation analysis each of the TiAlVN coatings indicated that the change of the gas ratio affects the surface morphology. The nano-indentation results demonstrated that coatings deposited with the gas ratio of Ar:N2 being 9:1 exhibited the highest hardness and elastic modulus. Moreover, with the various gas ratio of Ar:N2, ball-on-disc against SUJ2 ball in air at room temperature indicated friction coefficient from 0.43 to 0.58 in dry condition and 0.073 to 0.12 in oil condition, respectively, which is related to the surface roughness and grain sizes of the coatings.
Transformation Through Unbundling: Visualizing the Global FinTech Ecosystem
Authors: Basole Rahul C. , Patel Shiv S.
Published: December 2018

The infusion of digital technology into financial services, also known as FinTech, is creating a massive disruption of the entire financial sector. Services traditionally offered by incumbents are now rapidly unbundled by a growing set of startups, leading to new models of collaboration and a significant shift in power. This study provides insight into the structure of the FinTech ecosystem using data-driven visualizations of 6,493 global companies across 24 market segments. We focus on two types of ecosystem entities, namely, (1) firms that create, offer, and acquire FinTech services and (2) investors that fund and enable them. Our analyses reveal a highly skewed global footprint of FinTech activities, differential growth patterns across ecosystem segments, highly interdependent network structure, and a variegated nature of investments and acquisitions led by key incumbents and venture capital firms. We conclude with theoretical and managerial implications and discuss opportunities for future service ecosystem research.

Este estudo tem por objetivo investigar o processo de colaboração na produção de textos em escrita das línguas de sinais (ELiS), realizado individualmente e colaborativamente por alunos surdos. Como objetivo específico, buscamos verificar as percepções dos alunos acerca do processo de escrever em ELiS individualmente e colaborativamente. Os dados desta pesquisa advêm do estudo de Freitas (2016), do qual participaram quatro alunos surdos, de uma turma do curso de Letras: Libras da Universidade Federal de Goiás. Do ponto de vista metodológico, trata-se de um estudo de caso qualitativo, e os dados foram obtidos por meio de entrevistas, filmagens, questionários e textos dos participantes. Foram analisados seis textos, dos quais quatro foram escritos individualmente por cada participante e dois que foram escritos em pares. A análise de dados baseou-se nas contribuições de Barros (2008, 2015, 2016), Figueiredo (2001, 2006, 2015) e Vygotsky (1998). Este trabalho visa responder às seguintes perguntas: i) Quais as percepções dos participantes acerca de escrever em ELiS individualmente e em pares? ii) Quais as possíveis contribuições do trabalho colaborativo na produção de textos em ELiS? Os resultados mostraram que a mediação entre os participantes, ao dialogarem sobre a escrita das línguas de sinais (ELiS), possibilitou-lhes aprender uns com os outros e a refletir sobre a forma correta para escrita do sinal em Libras/ELiS, feito que não ocorreu quando produziram seus textos individualmente. Esperamos que esta pesquisa possa trazer reflexões sobre o ensino de escrita de sinais dentro da perspectiva da aprendizagem colaborativa nos espaços educacionais no Brasil.
Desalinhos caiçaras: identidades tradicionais em xeque na (tentativa de) construção de um projeto de educação diferenciada
Authors: Biar Liana De Andrade
Published: December 2018

Esta pesquisa nasce do desejo de contribuir para a construção de um projeto de educação diferenciada para as escolas do primeiro segmento do Ensino Fundamental em territórios caiçaras. Tendo em vista o interesse em construir conhecimento sobre essa comunidade, realizou-se uma microetnografia (Erickson, 2004) de um evento de letramento (Soares, 1999). Através da análise de pequenas narrativas (Bamberg e Georgakopoulou, 2008; Bastos, 2009) e aspectos interacionais que emergiram desse encontro, procurou-se construir entendimentos acerca da complexidade identitária da comunidade em foco. A análise dos dados trouxe à superfície dicotomizações rígidas, embates e resistências que compõem as reivindicações identitárias dos participantes. e uma comunidade que se move com cautela entre o desejo de aderir às mudanças da modernidade e a necessidade de garantir seus direitos como povo tradicional.
As limitações ao poder de tributar e os direitos fundamentais do contribuinte: análise a partir da classificação da norma jurídica segundo Robert Alexy | Limitations on the power to tax and the fundamental rights of the tax payer: analysis from the legal classification according to Robert Alexy
Authors: Said Silva Déborah Regina
Published: December 2018

Busca-se classificar os elementos normativos das limitações ao poder de tributar, segundo as espécies normativas trazidas por Robert Alexy, quais sejam: regra e princípio, no intuito de verificar de que forma essas normas podem e devem ser aplicadas pela jurisdição. A análise parte da classificação desses elementos normativos como direitos fundamentais do contribuinte, para posterior enquadramento como cláusulas pétreas segundo a Constituição Federal de 1988. A metodologia utilizada é propriamente a dogmática, a partir da análise de fontes secundárias sobre o tema, com investigação exclusivamente jurídica. A hipótese apresentada foi confirmada, no sentido da possibilidade de classificação dos princípios tributários e imunidades tributárias em regras ou princípios, podendo-se aplicar o juízo de ponderação apenas nas normas classificadas como princípios.
Como normas constitucionais colapsam | How Constitutional Norms Break Down
Authors: Chafetz Josh , Pozen David E.
Published: December 2018

A partir do momento em que Donald Trump foi eleito presidente, críticos se angustiaram com o colapso das normas constitucionais. A história demonstra, no entanto, que as normas constitucionais estão perpetuamente em fluxo. A principal fonte de instabilidade não é que essas regras não-escritas possam ser destruídas por políticos que negam sua legitimidade, sua validade ou seu valor. Na verdade, a principal fonte de instabilidade é que as normas constitucionais podem ser decompostas- interpretadas dinamicamente e aplicadas de formas consideradas adequadas, mas que limitam sua capacidade de restringir a conduta de agentes do governo.Este artigo chama a atenção para essa instabilidade latente e, ao fazê-lo, começa a taxonomizar e teorizar a estrutura da mudança da norma constitucional. Exploramos alguns dos diferentes modos em que normas não-escritas colapsam em nosso sistema constitucional e os diferentes perigos e oportunidades associados a cada um deles. Além disso, argumentamos que, sob certas condições plausíveis, será mais preocupante quando as normas forem sutilmente revisadas do que quando forem abertamente desprezadas. Este argumento um tanto paradoxal sugere que muitos comentaristas têm julgado de forma equivocada nosso momento atual: o flagrante desafio do presidente Trump às normas pode não ser uma ameaça tão grande à nossa democracia constitucional como a deterioração mais complexa de normas em curso em outras instituições.
BEIJA-FLOR DE NILÓPOLIS E NILÓPOLIS DA BEIJA-FLOR: MECANISMOS DE UMA CONSTRUÇÃO IDENTITÁRIA E DE PODER NA BAIXADA FLUMINENSE
Authors: Albuquerque Enderson Alceu Alves
Published: December 2018

De pouca expressão no contexto econômico da Região Metropolitana do Rio de Janeiro (RMRJ), a Escola de Samba Beija-Flor de Nilópolis empresta ao município que a sedia um lugar de destaque no aspecto cultural em escala nacional. Devido a essa característica e a sua importância enquanto formadora de identidade, a agremiação foi apropriada por um grupo familiar que passou a utilizá-la como ferramenta política. Com efeito, o trabalho em questão pretende analisar as articulações e o modus operandi que possibilitaram a esse clã manter o controle político da cidade, tendo como pano de fundo o uso da referida instituição carnavalesca. A investigação apontou que esse domínio se estabeleceu de forma mais assertiva a partir da segunda metade da década de 1970, quando a Escola de Samba passou a ter maior notoriedade nas disputas carnavalescas e foi posteriormente ampliado através da associação estabelecida entre esses membros políticos e às ações sociais promovidas pela Beija-Flor no município.
O USO DE GEOTECNOLOGIAS ASSOCIADO A METODOLOGIAS PARTICIPATIVAS NO ENSINO: APLICAÇÃO EM ESCOLAS MUNICIPAIS DO PRIMEIRO DISTRITO DE PETRÓPOLIS

Published: December 2018

Embora a difusão das geotecnologias já seja uma realidade cotidiana, sua inserção como ferramenta de apoio no ensino ainda é incipiente. Essas geotecnologias associadas às metodologias participativas na aplicação escolar, permitem o envolvimento direto dos alunos no processo de produção das informações geográficas e na confecção dos mapas. Dessa forma, o presente trabalho propôs a criação de uma proposta metodológica de atividade escolar baseada na utilização de geotecnologias associada a metodologias participativas para atender as demandas dos eixos temáticos da disciplina de História, Geografia, Turismo e Educação para o Trânsito de Petrópolis (HGPT-ET). A metodologia do trabalho dividiu-se em três etapas: a análise e leitura do referencial curricular do ensino fundamental e dos cadernos pedagógicos; a definição da atividade e da ferramenta a ser utilizada e, por fim, a realização de oficinas práticas em duas escolas municipais. Como resultados, obteve-se um mapa em versões interativa e analógica do município de Petrópolis com os pontos e as informações coletadas pelos alunos. A proposta metodológica possui o intuito de servir não apenas como exercício, mas como material pedagógico da disciplina específica sobre a cidade, preenchendo uma lacuna de materiais didáticos sobre Petrópolis. Palavras-chave: geotecnologias, metodologias participativas, proposta metodológica, HGPT-ET, ensino.
Oral Manifestations of Secondary Hyperparathyroidism: A Case Report and Literature Review
Authors: Cheng Jordan
Published: December 2018

A 52-year-old male with secondary hyperparathyroidism resulting from polycystic kidney disease, undergoing dialysis for 18 years, is documented. The case showed radiographic mandibular bilateral osteolytic lesions with ground glass appearance, diminished lamina dura, maxillary horizontal bone loss, but no maxillofacial expansion. Additionally, cases of hyperparathyroidism are reviewed to associate oral radiographic features with disease severity. The review suggests that in secondary hyperparathyroidism: 1) jaw demineralization, lamina dura loss, and osteolytic lesions occur with varying consistency depending on disease stage; 2) there is no gender predilection of oral manifestation occurrence; and 3) with advancing age, lamina dura changes may occur with increasing frequency.

CPD/Clinical Relevance: This article discusses the oral radiographic signs and symptoms that present in patients with secondary hyperparathyroidism.

Bourgeois worlds and urban nightmares: The post-Ottoman Balkan City through the lens of Milutin Uskoković’s Newcomers
Authors: Jovanović Miloš
Published: December 2018

In the nineteenth century, the bourgeois elites of newly minted national capitals Belgrade and Sofia sought to produce ‘European’ urban space, their first step on a path to industrial modernity and a new relationship with the world. When such designs failed, their execution left real, devastating material consequences. This article explores the underside of elite dreams through Milutin Uskoković’s Newcomers (1910). Set in 1906 Belgrade, the novel’s tragic form emphasizes the futility of bourgeois aspirations on the periphery of global capital. I expand on such themes through archival sources, which consistently describe the post-Ottoman city as a landscape of dispossession. Ultimately, I argue that urban modernity has historically been informed by failed elite dreams and their resulting urban nightmares, particularly in spaces off-centre to capitalist flows.
