Material apostilado em análise: gêneros digitais no ensino de língua portuguesa
Authors: Stutz Lidia , Cacilho Marco Antonio
Published: June 2015

Sabe-se que na rede privada o ensino apostilado constitui-se o principal instrumento de mediação das atividades do professor. Assim, buscamos analisar uma unidade de ensino sobre gêneros digitais proposta em material apostilado e investigar se as atividades mobilizam as capacidades de linguagem. O recorte que apresentamos é uma análise de atividades de leitura e escrita em apostila adotada por uma escola de uma cidade localizada na região central do Paraná. A análise torna-se relevante por levar-nos a uma reflexão sobre as propostas de ensino subjacentes ao material. O arcabouço teórico-metodológico é do interacionismo sociodiscursivo com o conceito de gêneros textuais (BRONCKART, 2012; SCHNEUWLY, 2004), as noções de capacidades de linguagem e macroestrutura (DOLZ; SCHNEUWLY, 2004; DOLZ; TOULOU, 2008), bem como as noções de gêneros digitais MARCUSCHI, 2008; XAVIER, 2010) e material apostilado (BUNZEN, 2001) guiam o nosso estudo. Concluímos que as atividades de forma geral mobilizam diferentes capacidades de linguagem, havendo, porém, algumas lacunas a revisar como carga horária insatisfatória da disciplina, produção de textos sem função social e o desenvolvimento de atividades que possibilitem analisar a fundo as capacidades de linguagem dos alunos.
Discurso, mídias e ensino: caminhos possíveis
Authors: Silva Sandro Luis
Published: June 2015

O processo de ensino-aprendizagem não pode ignorar as transformações pelas quais passa a realidade. É preciso que a escola se aproxime dos fatos reais e os traga para a sala de aula, promovendo uma reflexão sobre eles. Dentre as várias abordagens que podem ser tratadas pela instituição escolar, escolhemos as mídias, que cada vez mais se fazem presentes no dia a dia dos cidadãos. Este artigo objetiva algumas reflexões sobre os possíveis diálogos entre discurso, mídia e ensino, considerando que se devem trazer para a sala de aula as diferentes linguagens, com o objetivo de favorecer o desenvolvimento de competências e habilidades de leitura e de produção dos diferentes discursos que permeiam a sociedade contemporânea. Para atingir este objetivo, buscamos dialogar com os estudos de Maingueneau (2004, 2014) no que diz respeito ao discurso, Martin-Barbero (1996, 2012) e Setton (2011) no tocante às mídias, e Silva (2011) e Sanfelice (2009), no que se refere à interação e sala de aula. A partir dessas notas sobre as interfaces entre discurso, mídia e ensino, é possível afirmar que a inserção das mídias nos diferentes suportes torna de fato o ensino-aprendizagem mais significativo para os sujeitos envolvidos nesse processo.

Published: June 2015

Consideramos que o conhecimento da organização sociorretórica do gênero homepage auxilia o designer instrucional a promover uma interação positiva dos participantes de cursos online a distância com o conteúdo pedagógico e, consequentemente, a promover o seu envolvimento com os processos de ensino e de aprendizagem. Neste trabalho, examinamos essa organização nas homepages de dez disciplinas oferecidas no curso de graduação de Matemática – Licenciatura – Modalidade a Distância da PUC-SP, na perspectiva sociorretórica de análise de gêneros (SWALES, 1990), na qual se consideram os propósitos comunicativos do gênero; as unidades funcionais (movimentos retóricos) que o caracterizam e as estratégias retóricas empregadas para o alcance de tais propósitos. A organização sociorretórica da informação nas homepages das disciplinas selecionadas revela-nos a prática social adotada pelos usuários desse gênero. Conhecer essa organização permite ao designer e ao professor desenvolver um design instrucional mais eficiente, visto que a compreensão do modo como funciona o gênero nas circunstâncias em que é produzido auxilia-os a atender às necessidades situacionais do contexto de ensino e aprendizagem, de forma que a organização do conteúdo e das atividades pedagó- gicas seja compreensível e corresponda às expectativas dos aprendizes.

O naturalista Veloso
Authors: Kury Lorelai
Published: June 2015

O artigo analisa a atuação de frei Veloso como naturalista e busca demonstrar que tanto sua atividade de botânico quanto o trabalho de editor eram consistentes com as características da história natural do Iluminismo. A celebridade adquirida posteriormente por Veloso foi sendo construída no âmbito da exaltação de “grandes homens” do período colonial e na utilização de suas pesquisas pela botânica. O fato de Veloso e sua equipe terem adotado o sistema lineano permitiu que sua obra fosse reconhecida pelos taxonomistas como válida, mesmo posteriormente, apesar de estar desatualizada na época de sua publicação.
Ser brâmane na Goa da época moderna
Authors: Xavier Ângela Barreto , Županov Ines G.
Published: June 2015

O objetivo deste estudo é analisar as estratégias de sobrevivência desenvolvidas pelos brâmanes de Goa durante a dominação imperial portuguesa entre os séculos XVII e XVIII. No caso de Goa, apesar de viverem sob um poder cristão intolerante, alguns brâmanes procuraram recuperar a sua velha identidade. A maioria, porém, decidiu converter-se ao Cristianismo, transformando-se na comunidade de brâmanes católicos. Todavia, mesmo depois de cristianizados, estes brâmanes mantiveram ligações para além dos contextos da dominação imperial portuguesa. Essas ligações também contribuíram, de uma forma ou de outra, para forjar a sua identidade bramânica. As diferentes atitudes destes brâmanes perante a identidade bramânica e o poder imperial português permitem-nos colocar algumas questões: Quais foram as estratégias desenvolvidas pelos brâmanes de Goa, e o que estas revelam sobre a relação entre o poder imperial português e a construção de uma identidade bramânica? O que é que estas estratégias nos revelam sobre os brâmanes de Goa e suas características? E de que maneira estas experiências se articularam com outras experiências indianas de formação da identidade bramânica na época moderna, nomeadamente as que dizem respeito ao seu envolvimento no mundo da burocracia política e da carreira eclesiástica?
CARTOGRAFIA HISTÓRICA E GEOPROCESSAMENTO: O EXEMPLO DOS MAPAS DOS PADRES MATEMÁTICOS, DE 1734, E DO CÁLCULO DE RENDIMENTOS GERAIS DO BISPADO DE MARIANA, DE 1752
Authors: Castro José Flávio Moraes
Published: June 2015

Os mapas históricos vem sendo objeto de interesse especial de pesquisadores de variadas áreas, pela sua importância como registro de valores culturais da sociedade no espaço e no tempo. Este trabalho tem por objetivo analisar as interfaces entre a Cartografia Histórica e o geoprocessamento, adotando-se, como exemplo, o georreferenciamento e a  vetorização dos mapas da Capitania de Minas Gerais elaborados pelos padres matemáticos Diogo Soares e Domingos Capassi, em 1734. Pretende-se, também, representar o cálculo de rendimentos gerais do Bispado de Mariana, de 1752, por meio de mapas temáticos. Propõe-se um roteiro metodológico de utilização do geoprocessamento em informações históricas, fundamentado nos princípios da "Semiologia Gráfica" para o tratamento da informação espacial.
A CARTOGRAFIA NO ENSINO: OS DESAFIOS DO MAPA DA GLOBALIZAÇÃO
Authors: Fonseca Fernanda Padovesi
Published: June 2015

A partir de uma reflexão sobre o papel epistemológico da cartografia na relação com a complexidade do mundo, reflexão essa que procura refutar a interpretação que o mapa simplifica o complexo, o artigo enfatiza que a grande questão do ensino da cartografia permanece sendo a desconexão existente entre as práticas cartográficas e as elaborações no interior da geografia. O artigo procura demonstrar isso por meio do exemplo contemporâneo do processo de globalização. Por sua vez, esse processo exige para seu entendimento novas elaborações no campo da geografia, e também uma atualização (ou renovação) do mapa-múndi, cuja versão convencional é incompatível com as novas realidades que estão criando um mundo de fato.
CONTRIBUIÇÕES DA CARTOGRAFIA AOS ESTUDOS DE GEOGRAFIA DA SAÚDE: INVESTIGANDO ASSOCIAÇÕES ENTRE PADRÕES ESPACIAIS
Authors: Barrozo Ligia Vizeu
Published: June 2015

A identificação de padrões na ocorrência de um evento é o ponto de partida para a investigação e a compreensão de fenômenos para os quais as dimensões espaço e tempo se associam de forma explanatória. Para ilustrar a potencialidade da análise espacial, avalio o padrão espacial da mortalidade por tuberculose de 2006 a 2009 entre residentes do município, a partir da agregação por Área de Ponderação (AP). Foi verificada a associação entre os riscos relativos e agrupamentos espaciais calculados e indicadores como o rendimento médio dos chefes de família e o número médio de moradores por domicílio. A taxa de mortalidade anual durante o período estudado foi de 2,6/100 mil habitantes. Foram encontrados 15 agrupamentos espaciais, sendo sete de alto risco e oito, de baixo. O agrupamento estatisticamente mais provável localiza-se na porção central do município. Apesar de explicar estatisticamente apenas 10% da distribuição da tuberculose, quase todos os agrupamentos de risco alto sobrepõem AP com rendimento abaixo da média do município. Algumas associações tradicionalmente consideradas evidentes do ponto de vista epidemiológico explicam apenas pequena parcela do complexo, remetendo-nos à necessidade da busca da integração multi-escalar e transdiciplinar.

Published: June 2015

A gestão de bacias compartilhadas constitui um dos desafios na implementação dos instrumentos da Política Nacional de Recursos Hídricos no Brasil, necessitando de estudos detalhados, coordenação política e cooperação entre os participantes para que seja plenamente efetivada. Além de entraves relacionados a conflitos de interesses entre as unidades políticas usuárias desses recursos, o planejamento e a gestão de bacias hidrográficas que abrangem territórios de mais de um Município ou Estado da Federação Brasileira, se reveste de complexidade em função de questões peculiares relacionadas à articulação dos conhecimentos técnico-científicos disponíveis. Nesse sentido, a elaboração do Mapa Geomorfológico e do Mapa de Fragilidade Geoambiental da Unidade de Gestão de Recursos Hídricos Paranapanema com o objetivo principal de contribuir com as ações do CBH Paranapanema voltadas ao planejamento de recursos hídricos, exemplificam o desafio de integração de estudos produzidos com níveis de detalhamento diferenciados, decorrentes de procedimentos técnico-operacionais distintos. Assim, este artigo apresenta à comunidade geográfica os caminhos percorridos e as soluções encontradas para a compatibilização e integração de documentos cartográficos pré-existentes tais como o Mapa Geomorfológico do Estado de São Paulo, o Mapa Geomorfológico do Estado do Paraná e o Mapa de Vulnerabilidade Geoambiental do Estado do Paraná.
ANÁLISE MORFOMÉTRICA E MORFOTECTÔNICA DO GRÁBEN DO RIO MAMANGUAPE E ADJACÊNCIAS, BORDA ORIENTAL DO ESTADO DA PARAÍBA, BRASIL
Authors: Furrier Max Furrier , Nóbrega Wesley Ramos , Souza Alexandre Dos Santos
Published: June 2015

O presente trabalho está fundamentado na utilização de três cartas topográficas na escala 1:25.000, que estão localizadas na borda oriental do estado da Paraíba, região Nordeste do Brasil. Com essa escala de detalhe, tornou-se possível um mapeamento inédito do gráben do rio Mamanguape, em seu médio e baixo curso. Inicialmente, a vetorização das cartas topográficas possibilitou a elaboração dos mapas temáticos e do Modelo Digital do Terreno (MDT), por meio dos quais obteve-se uma percepção particularizada de toda a configuração morfológica da área de estudo, que apresenta diferenças altimétricas discrepantes entre suas bordas norte e sul, percorrendo toda a adjacência do gráben. O relevo da área apresenta vertentes em ombreiras ou shoulders, padrões assimétricos das redes de drenagem, orientações anômalas, inflexões bruscas de vários canais fluviais e recuos acelerados de cabeceiras de drenagem. Essas características atestam para um controle morfotectônico da área, haja vista que apenas o fator climático impossibilitaria o padrão morfológico encontrado.

Published: June 2015

O presente artigo analisa as percepções de moradores em áreas de risco a desastres naturais associados a inundações no bairro Vila Carli, em Guarapuava-PR sobre as causas das inundações, uma vez que grande porção de área do bairro Vila Carli é inundada durante eventos extremos de chuva. Uma pesquisa exploratória com 40 moradores foi realizada, nos meses de agosto e setembro de 2013. Os resultados apontaram que a maioria dos moradores atribui a ocorrência de desastres naturais associados à inundação no bairro, à deposição de resíduos sólidos (lixo) em lugares inadequados e que a prevenção e mitigação destes eventos dependem de medidas estruturais e pontuais.
Fairness, Political Obligation, and the Justificatory Gap
Authors: Zhu Jiafeng
Published: June 2015

The moral principle of fairness or fair play is widely believed to be a solid ground for political obligation, i.e., a general prima facie moral duty to obey the law qua law. In this article, I advance a new and, more importantly, principled objection to fairness theories of political obligation by revealing and defending a justificatory gap between the principle of fairness and political obligation: the duty of fairness on its own is incapable of preempting the citizen’s liberty to reciprocate fairly in ways other than obeying the law. This justificatory gap is unaffected by the ongoing debate between the voluntarist and the nonvoluntarist accounts of fairness, and it cannot be bridged by the two arguments that are perhaps implicit in Klosko’s account, namely the presumptive benefits argument and the democratic procedure argument.
A revision of generic boundaries and nomenclature in the North American cleomoid clade (Cleomaceae)
Authors: Roalson Eric H. , Hall Jocelyn C. , Riser II James P. , Cardinal-McTeague Warren M. , Cochrane Theodore S. , Sytsma Kenneth J.
Published: June 2015

The family Cleomaceae is in need of taxonomic revision, which begins here with a set of taxa informally recognized as the North American cleomoid clade. This group is evaluated first because molecular-based analyses almost comprehensively sample this lineage. These investigations revealed that the two largest genera, Cleomella and Peritoma, are para- or polyphyletic. Strong support from molecular data necessitates name changes for these taxa. Furthermore, controversy exists on the recognition of the remaining genera, owing to morphological variation and specialization. Three possible classification scenarios are described to accommodate monophyletic lineages based on previously-published evidence. The option to create the single large genus Cleomella is proposed, and as a result one new name, Cleomella oxystyloides, is provided, and 12 new combinations are made: C. arborea, C. arborea var. angustata, C. arborea var. globosa, C. californica, C. jonesii, C. lutea, C. multicaulis, C. palmeri, C. platycarpa, C. refracta, C. serrulata, and C. sparsifolia. Two lectotypes and one isolectotype are designated, and another lectotype is confirmed.
Two new species of Calanthe (Orchidaceae: Epidendroideae) from Korea
Authors: Oh Sang-Hun , Suh Hwa-Jung , Park Chong-Wook
Published: June 2015

Two new species, Calanthe insularis S.H.Oh, H.J.Suh & C.-W.Park and Calanthe rubra S.H.Oh, H.J.Suh & C.-W.Park, are described, illustrated, and compared with closely related species. Calanthe insularis, distributed in the southwestern region of Korea and Tsushima Island in Japan, is morphologically similar to C. aristulifera and C. striata, but it is distinguished from the last two species in its creamy yellow and pale orange-yellow flowers, arcuate spur as long as the lip, pale orange-yellow pedicels, and green ovary with pale green ridges. Calanthe rubra, from Gageodo Island, Korea, is similar to C. striata and C. insularis, but differs from them in its much smaller flowers with purplish red sepals and petals and the white spur.

Field Observations of Surf Zone–Inner Shelf Exchange on a Rip-Channeled Beach
Authors: Brown Jenna A. , MacMahan Jamie H. , Reniers Ad J. H. M. , Thornton Ed B.
Published: June 2015

Cross-shore exchange between the surf zone and the inner shelf is investigated using Lagrangian and Eulerian field measurements of rip current flows on a rip-channeled beach in Sand City, California. Surface drifters released on the inner shelf during weak wind conditions moved seaward due to rip current pulses and then returned shoreward in an arcing pattern, reentering the surf zone over shoals. The cross-shore velocities of the seaward- and shoreward-moving drifters were approximately equal in magnitude and decreased as a function of distance offshore. The drifters carried seaward by the rip current had maximum cross-shore velocities as they exited the surf zone and then decelerated as they moved offshore. The drifters moving shoreward accelerated as they approached the surfzone boundary with maximum cross-shore velocities as they reentered the surf zone over shoals. It was found that Stokes drift was not solely responsible for the onshore transport across the surfzone boundary. The cross-shore diffusivity on the inner shelf was greatest during observations of locally contained cross-shore exchange. These field observations provide evidence that the cross-shore exchange between the surf zone and inner shelf on a rip-channeled beach is due to wave-driven rip current circulations and results in surface material being contained within the nearshore region.
Sensitivity of Central Oklahoma Convection Forecasts to Upstream Potential Vorticity Anomalies during Two Strongly Forced Cases during MPEX
Authors: Torn Ryan D. , Romine Glen S.
Published: June 2015

The role of upstream subsynoptic forecast errors on forecasts of two different central Oklahoma severe convection events (19 and 31 May 2013) characterized by strong synoptic forcing during the Mesoscale Predictability Experiment (MPEX) are evaluated by applying the ensemble-based sensitivity technique to WRF ensemble forecasts with explicit convection. During both cases, the forecast of the timing and intensity of convection over central Oklahoma is modulated by the southward extent of upstream midtropospheric potential vorticity anomalies that are moving through the base of a larger-scale upstream trough but pass by central Oklahoma prior to convective initiation. In addition, the convection forecasts are also sensitive to the position of lower-tropospheric boundaries, such that moving the boundaries in a manner that would lead to increased equivalent potential temperature over central Oklahoma prior to convective initiation leads to more precipitation. Statistical PV inversion and correlation calculations suggest that the midtropospheric PV and near-surface boundary sensitivities are not independent; the winds associated with the PV error can modulate the position of the lower-tropospheric boundary through advection in a manner consistent with the implied sensitivity. As a consequence, it appears that reducing the uncertainty in specific upstream subsynoptic features prior to convective initiation could improve subsequent forecasts of severe convection.
Class at the Intersection of Race and Gender
Authors: Reimers Faye A. , Stabb Sally D.
Published: June 2015

Consistent with psychology’s call to action for an inclusive and intentional focus on social class, we conducted a content analysis examining class variables relative to race and gender variables in articles over a 15-year period in The Counseling Psychologist and the Journal of Counseling Psychology. Articles were classified by degree of inclusion of these variables, resulting in three categories: mentioned, integrated, and primary. Despite the recent trend toward class inclusion, only 560 of 1,440 studies (39%) included all three variables at any level. Articles where all variables were “Primary” comprised only 1.9% ( n = 28) of the articles we reviewed. Using a qualitative content analysis and intersectionality lens, only 15 of the 28 studies thoroughly integrated class, race, and gender variables. Results highlight a recent, significant increase in attention to class issues, as well as the continued need to place class analysis on par with other important diversity variables. Implications are discussed.
Co-production in healthcare: rhetoric and practice
Authors: Vennik Femke D. , van de Bovenkamp Hester M. , Putters Kim , Grit Kor J.
Published: June 2015

Co-production in healthcare is receiving increasing attention; however, insight into the  process of co-production is scarce. This article explores why hospitals involve patients and staff in co-production activities and hospitals’ experiences with co-production in practice. A qualitative study with semi-structured interviews ( N = 27), observations (70 hours) and document analysis was conducted in five Dutch hospitals, which involved patients and staff in order to improve services. The results show that hospitals have different motives to involve patients and staff and have adapted existing methods to involve patients. Interestingly, areas of improvement proposed by patients were often already known. However, the process of co-production did contribute to quality improvement in other ways. The  process of co-production stimulated hospitals’ thinking about how to realize quality improvements. Quality improvements were facilitated by this process as seeing patients and hearing their experiences created a sense of urgency among staff to act on the improvement issues raised. Moreover, the experiences served to legitimatize improvements to higher management bodies.

Points for practitioners

Different participation methods can bring patients’ experiences with healthcare services to the fore, which can be used for quality improvement. Our study shows that adapting existing methods to local hospital resources is likely to be beneficial for co-production processes within a given context. However, adapting and tailoring also poses risks. Tailoring activities, such as using criteria to select patients, influence what is considered to be legitimate patient input. In addition, as the co-production process is important, the method should consist of an organized trajectory in which patients and staff are involved and personal experiences are presented. Therefore, project teams need to critically reflect on the consequences of adaptations and tailoring actions, and their desirability, when carrying out quality improvement projects.
The ADAMTS1 Gene Is Associated with Familial Mandibular Prognathism

Published: June 2015

Mandibular prognathism is a facial skeletal malocclusion. Until now, the genetic mechanism has been unclear. The goal of this study was to identify candidate genes or genomic regions directly associated with mandibular prognathism development, by employing whole genome sequencing. A large Chinese family was recruited, composed of 9 affected and 12 unaffected individuals, and the inheritance pattern of this family tends to be autosomal dominant. A single-nucleotide missense mutation in the ADAMTS1 gene (c. 742I>T) was found to segregate in the family, given that the affected individuals must be heterozygous for the mutation. For mutation validation, we screened this candidate mutation and 15 tag single-nucleotide polymorphisms in the coding sequence of ADAMTS1 among 230 unrelated cases and 196 unrelated controls using Sequenom Massarray and found that 3 in 230 cases carried this mutation and none of the controls did. Final results suggested that 2 single-nucleotide polymorphisms (rs2738, rs229038) of ADAMTS1 were significantly associated with mandibular prognathism.
Subjective evaluations of fabric-evoked prickle using the unidimensional rating scale from different body areas
Authors: Asad Rabie AM , Yu Weidong , Siddiqui Qasim , Vincent Mukwaya , Wang Qicai
Published: June 2015

Fabric-evoked prickle sensation is one of the most important criteria used by consumers in judging clothing comfort. In this study, a measurement method that is capable of characterizing and ranking the subjective prickle score sensation of various wear fabric products has been developed using seven different materials. A 1–7 subjective rating scale was adopted for response measurement and eight different fabrics varying in fiber composition were evaluated by 31 subjects. In addition, the sensitivity of six separate areas of the human skin were tested, namely the right forearm, back neck, the upper back, abdomen, right side waist and right inner thigh. The testing technique was standardized, to incorporate within-subject reliability and between-subject uniformity. The result is rational with a barely slight prickle sensation for the cotton, cashmere and cotton/polyester fabrics and high prickle score feeling for the ramie, wool and jute fabrics. The influence of different human body part areas was investigated when subjects rated the wear fabric based on prickle sensation. The result showed no significant difference between body parts ( P < 0.05).
Testing the Dynamic Model
Authors: Evans Stephen
Published: June 2015

A recent special issue of the Journal of English Linguistics has highlighted the paucity of empirical research into the evolutionary dynamics of Outer Circle varieties of English. This article seeks to narrow this conspicuous research gap by presenting the findings of a corpus-based study of the evolution of the Hong Kong English (HKE) lexicon. The investigation was inspired by Schneider’s innovative theoretical framework, the Dynamic Model, which claims that a uniform process involving a sequence of five phases underlies the emergence of postcolonial Englishes. The study was based on the principle that such phases should emerge from the analysis of a uniform set of diachronic data, which in this case consists of a ninety-one-million-word corpus of Legislative Council proceedings (1858-2012). By tracking the use of HKE words in the corpus, the study is able to identify distinct phases in the evolution of the lexicon and thereby provide evidence of the developmental cycle of HKE as a variety.
Stochastic Curtailment of Questionnaires for Three-Level Classification
Authors: Smits Niels , Finkelman Matthew D. , Kelderman Henk
Published: June 2015

In clinical assessment, efficient screeners are needed to ensure low respondent burden. In this article, Stochastic Curtailment (SC), a method for efficient computerized testing for classification into two classes for observable outcomes, was extended to three classes. In a post hoc simulation study using the item scores on the Center for Epidemiologic Studies–Depression Scale (CES-D) of a large sample, three versions of SC, SC via Empirical Proportions (SC-EP), SC via Simple Ordinal Regression (SC-SOR), and SC via Multiple Ordinal Regression (SC-MOR) were compared at both respondent burden and classification accuracy. All methods were applied under the regular item order of the CES-D and under an ordering that was optimal in terms of the predictive power of the items. Under the regular item ordering, the three methods were equally accurate, but SC-SOR and SC-MOR needed less items. Under the optimal ordering, additional gains in efficiency were found, but SC-MOR suffered from capitalization on chance substantially. It was concluded that SC-SOR is an efficient and accurate method for clinical screening. Strengths and weaknesses of the methods are discussed.
Classifier and feature set ensembles for web page classification
Authors: Onan Aytuğ
Published: June 2015

Web page classification is an important research direction on web mining. The abundant amount of data available on the web makes it essential to develop efficient and robust models for web mining tasks. Web page classification is the process of assigning a web page to a particular predefined category based on labelled data. It serves for several other web mining tasks, such as focused web crawling, web link analysis and contextual advertising. Machine learning and data mining methods have been successfully applied for several web mining tasks, including web page classification. Multiple classifier systems are a promising research direction in machine learning, which aims to combine several classifiers by differentiating base classifiers and/or dataset distributions so that more robust classification models can be built. This paper presents a comparative analysis of four different feature selections (correlation, consistency, information gain and chi-square-based feature selection) and four different ensemble learning methods (Boosting, Bagging, Dagging and Random Subspace) based on four different base learners (naive Bayes, K-nearest neighbour algorithm, C4.5 algorithm and FURIA algorithm). The article examines the predictive performance of ensemble methods for web page classification. The experimental results indicate that feature selection and ensemble learning can enhance the predictive performance of classifiers in web page classification. For the DMOZ-50 dataset, the highest average predictive performance (88.1%) is obtained with the combination of consistency-based feature selection with AdaBoost and naive Bayes algorithms, which is a promising result for web page classification. Experimental results indicate that Bagging and Random Subspace ensemble methods and correlation-based and consistency-based feature selection methods obtain better results in terms of accuracy rates.
An Administrative Data Approach to Examining Perioperative Antibiotic Use in Head and Neck Oncologic Surgery
Authors: Zevallos Jose P.
Published: June 2015

The choice of perioperative antibiotics for head and neck oncologic surgery is the subject of significant controversy. Given the ever‐increasing number of antibiotic options available, as well as the growing problem of antibiotic resistance, there is a need for renewed research on this important topic. In their recent publication, Langerman and colleagues explore the relationship between antibiotic choice, surgical site infections, and antibiotic‐induced complications in patients undergoing total laryngectomy. They demonstrate wide variability in antibiotic regimens among patients undergoing total laryngectomy, as well as an association between increased risk of surgical site infections and clindamycin use. This study addresses a controversial subject affecting the daily care of patients with head and neck cancer, and the findings have the potential to significantly affect management. It also highlights the strengths and inherent limitations of an administrative data approach to head and neck cancer clinical research.
Right upper lobe lung cancer: Resection through left anterior mediastinotomy
Authors: Sirois Marco , Arab Walid Abu , Turcotte Eric , Poulin Yannick
Published: June 2015

There is sparse information concerning approaches to metachronous lung cancer in patients who had a previous pneumonectomy for lung carcinoma. We describe the case of a 55-year-old woman who underwent a left pneumonectomy for lung carcinoma. Four years later, a radiological examination revealed a hypermetabolic nodule in the right upper lobe, which was located in the left hemithorax because of right lung hyperinflation and a mediastinal shift to the left. Wedge resection was carried out through a left anterior mediastinotomy. We believe that an anterior mediastinotomy represents a valuable option for the management of recurrent lung cancer after previous surgery.

Research in Graph-based Simultaneous Localization and Mapping has experienced a recent trend towards robust methods. These methods take the combinatorial aspect of data association into account by allowing decisions of the graph topology to be made during optimization. The Generalized Graph Simultaneous Localization and Mapping framework presented in this work can represent ambiguous data on both local and global scales, i.e. it can handle multiple mutually exclusive choices in registration results and potentially erroneous loop closures. This is achieved by augmenting previous work on multimodal distributions with an extended graph structure using hyperedges to encode ambiguous loop closures. The novel representation combines both hyperedges and multimodal Mixture of Gaussian constraints to represent all sources of ambiguity in Simultaneous Localization and Mapping. Furthermore, a discrete optimization stage is introduced between the Simultaneous Localization and Mapping frontend and backend to handle these ambiguities in a unified way utilizing the novel representation of Generalized Graph Simultaneous Localization and Mapping, providing a general approach to handle all forms of outliers. The novel Generalized Prefilter method optimizes among all local and global choices and generates a traditional unimodal unambiguous pose graph for subsequent continuous optimization in the backend. Systematic experiments on synthetic datasets show that the novel representation of the Generalized Graph Simultaneous Localization and Mapping framework with the Generalized Prefilter method, is significantly more robust and faster than other robust state-of-the-art methods. In addition, two experiments with real data are presented to corroborate the results observed with synthetic data. Different general strategies to construct problems from real data, utilizing the full representational power of the Generalized Graph Simultaneous Localization and Mapping framework are also illustrated in these experiments.
New methods for pre- and post-processing of stochastic simulations
Authors: Klostermann Sönke , Vogt Dietmar C
Published: June 2015

The aim of numerical simulation is a reliable prediction of real system’s behaviour, which is influenced by numerous uncertainties. In this work, a modelling process is developed for spatially localised modelling of uncertainties by random fields. The developed differential scale-space representation allows the derivation of a stochastic model that can be used to generate synthetic realisations based on a given sample. The post-processing of such stochastic simulation results is usually performed by means of statistic methods. However, this way only values of selected points in space and time can be evaluated and the associativity to the geometric model is lost. To overcome these limitations, a new concept to visualise geometric scatter and dependent statistic measures from stochastic simulation results is developed. The visualisation of the expected value geometry with statistic measures of dependent variables as well as surrounding probability envelopes by superimposed transparent geometry constitutes a holistic approach to evaluate stochastic simulation results.

Published: June 2015

Background

Studies reveal that migraine is often under-recognized, misdiagnosed and inadequately treated in the primary care setting.

Objective

The objective of this article is to assess primary care providers’ (PCP) knowledge and needs regarding migraine diagnosis and management.

Methods

We held semi-structured group interviews and distributed a brief questionnaire to PCPs in our hospital network. Building on the information from the interviews, we developed a comprehensive survey assessing PCPs’ knowledge about migraine. Descriptive analyses were performed.

Results

The initial interviews and brief questionnaires revealed that PCPs are aware of the prevalence of migraine but are uncertain about the details of management. Eighty-three of 120 physicians completed the comprehensive survey. Only 47% would order imaging for a new type of headache, 31% for worsening headache, and 35% for a headache unresponsive to treatment. Only 28% were familiar with the American Academy of Neurology guidelines on preventive treatment and 40% were familiar with the Choosing Wisely Campaign recommendations on migraine treatment. Just 34% were aware that opioids can cause medication-overuse headache. Non-pharmacologic treatment was not usually recommended. PCPs favored educational opportunities involving direct contact with headache physicians (56%).

Conclusions

PCPs are not universally aware of the specific recommendations for managing migraine patients. Future work should focus on innovative ways to provide decision support and education for PCPs caring for migraineurs.

Published: June 2015

Introduction

The objective of this review is to provide an evidence-based discussion of different treatment strategies for medication-overuse headache (MOH).

Method

We searched PubMed for articles discussing the treatment and prognosis of MOH published between 2004 and August 2014. Titles, abstract and articles were reviewed systematically. The level of evidence provided by each study of the included articles was determined according to the American Academy of Neurology Clinical practice guideline manual. We discuss the level of evidence to support the early discontinuation/withdrawal of overused medications, the level of evidence to support the use of preventive treatment, the short- and long-term prognosis, and the outcome according to the class of drug overused in patients diagnosed with MOH.

Results

The initial search resulted in 1313 articles; 68 articles met our inclusion criteria and were discussed. The level of evidence to support early discontinuation of overused medications alone is low due to the absence of controlled studies. Adding preventive medication to early discontinuation led to a better outcome than early discontinuation alone. For patients with chronic migraine (CM) and medication overuse (MO), there are large randomized control trials supporting the use of onabotulinumtoxinA and topiramate without early discontinuation of overuse; however, the evidence is limited since data were obtained from post hoc analysis.

Conclusion

Considering current available evidence and the systemic toxicity of overusing acute headache medication, we suggest discontinuation of the overused medication with the addition of preventive medication. Appropriately sized, randomized controlled trials evaluating the safety and long-term efficacy of preventive medication plus early discontinuation of overuse vs preventive medication alone vs early discontinuation of overuse alone are needed.
Increased Lateral Tibial Slope Is a Risk Factor for Pediatric Anterior Cruciate Ligament Injury
Authors: Dare David M. , Fabricant Peter D. , McCarthy Moira M. , Rebolledo Brian J. , Green Daniel W. , Cordasco Frank A. , Jones Kristofer J.
Published: June 2015

Background:

Increased posterior tibial slope is associated with increased risk of anterior cruciate ligament (ACL) injury in adults. A similar association has not been rigorously examined in children and adolescents.

Purpose:

To determine whether alterations in posterior tibial slope are associated with ACL tears in pediatric and adolescent patients and to quantify changes in tibial slope by age.

Study Design:

Case-control study; Level of evidence, 3.

Methods:

Magnetic resonance imaging (MRI) studies of the knee were reviewed by 3 raters blinded to each other in a 1:1 sample of cases and age- and sex-matched controls. A total of 76 skeletally immature ACL-injured knees were compared with 76 knees without ACL injury; the mean age of the study population was 14.8 ± 1.3 years. The posterior slope of the articular surface of the medial tibial plateau and lateral tibial plateau was measured by use of a method similar to that used in previous studies in adult populations. The current study technique differed in that the slope was measured on the cartilage surface, not the subchondral bone. Comparisons between knees were made with t tests, and Spearman correlation analysis was used to assess changes in tibial slope with advancing age.

Results:

Increased slope of the lateral tibial plateau (LTS) was significantly increased in ACL-injured patients compared with controls (5.7° ± 2.4° vs 3.4° ± 1.7°; P < .001). There was no statistically significant difference in the slope of the medial tibial plateau (MTS) in the ACL-injured and control knees (5.4° ± 2.2° vs 5.1° ± 2.3°; P = .42). There was no difference in LTS between male and female patients (4.46° vs 4.58°; P = .75). Receiver operating characteristic (ROC) analysis of the LTS revealed that a posterior tibial slope cutoff of >4° resulted in a sensitivity of 76% and a specificity of 75% for predicting ACL tears in this cohort. Spearman correlation analysis revealed that MTS and LTS decreased, or flattened, by 0.31° ( P = .028, correlation coefficient r = −0.18) and 0.37° ( P = .009, correlation coefficient r = −0.21) per year, respectively, as adolescents age.

Conclusion:

The LTS was significantly associated with an increased risk of ACL injury in pediatric and adolescent patients. The MTS was not associated with risk of injury. Posterior slope was found to decrease, or flatten, with age. A cutoff of >4° for the posterior slope of the lateral compartment is 76% sensitive and 75% specific for predicting ACL injury in this cohort. The LTS did not influence the incidence of ACL injury differently between sexes.
Risk of Anterior Cruciate Ligament Fatigue Failure Is Increased by Limited Internal Femoral Rotation During In Vitro Repeated Pivot Landings
Authors: Beaulieu Mélanie L. , Wojtys Edward M. , Ashton-Miller James A.
Published: June 2015

Background:

A reduced range of hip internal rotation is associated with increased peak anterior cruciate ligament (ACL) strain and risk for injury. It is unknown, however, whether limiting the available range of internal femoral rotation increases the susceptibility of the ACL to fatigue failure.

Hypothesis:

Risk of ACL failure is significantly greater in female knee specimens with a limited range of internal femoral rotation, smaller femoral-ACL attachment angle, and smaller tibial eminence volume during repeated in vitro simulated single-leg pivot landings.

Study Design:

Controlled laboratory study.

Methods:

A custom-built testing apparatus was used to simulate repeated single-leg pivot landings with a 4×-body weight impulsive load that induces knee compression, knee flexion, and internal tibial torque in 32 paired human knee specimens from 8 male and 8 female donors. These test loads were applied to each pair of specimens, in one knee with limited internal femoral rotation and in the contralateral knee with femoral rotation resisted by 2 springs to simulate the active hip rotator muscles’ resistance to stretch. The landings were repeated until ACL failure occurred or until a minimum of 100 trials were executed. The angle at which the ACL originates from the femur and the tibial eminence volume were measured on magnetic resonance images.

Results:

The final Cox regression model ( P = .024) revealed that range of internal femoral rotation and sex of donor were significant factors in determining risk of ACL fatigue failure. The specimens with limited range of internal femoral rotation had a failure risk 17.1 times higher than did the specimens with free rotation ( P = .016). The female knee specimens had a risk of ACL failure 26.9 times higher than the male specimens ( P = .055).

Conclusion:

Limiting the range of internal femoral rotation during repetitive pivot landings increases the risk of an ACL fatigue failure in comparison with free rotation in a cadaveric model.

Clinical Relevance:

Screening for restricted internal rotation at the hip in ACL injury prevention programs as well as in individuals with ACL injuries and/or reconstructions is warranted.
