Building a cloud in the southeast Atlantic: understanding low-cloud controls based on satellite observations with machine learning
Authors: Fuchs Julia , Cermak Jan , Andersen Hendrik
Published: November 2018

Abstract. Understanding the processes that determine low-cloud properties
and aerosol–cloud interactions (ACIs) is crucial for the estimation of their
radiative effects. However, the covariation of meteorology and aerosols
complicates the determination of cloud-relevant influences and the
quantification of the aerosol–cloud relation. This study identifies and analyzes sensitivities of cloud fraction and cloud
droplet effective radius to their meteorological and aerosol environment in
the atmospherically stable southeast Atlantic during the biomass-burning
season based on an 8-day-averaged data set. The effect of geophysical
parameters on clouds is investigated based on a machine learning technique,
gradient boosting regression trees (GBRTs), using a combination of satellite
and reanalysis data as well as trajectory modeling of air-mass origins. A
comprehensive, multivariate analysis of important drivers of cloud occurrence
and properties is performed and evaluated. The statistical model reveals marked subregional differences of relevant
drivers and processes determining low clouds in the southeast Atlantic. Cloud
fraction is sensitive to changes of lower tropospheric stability in the
oceanic, southwestern subregion, while in the northeastern subregion it is
governed mostly by surface winds. In the pristine, oceanic subregion
large-scale dynamics and aerosols seem to be more important for changes of
cloud droplet effective radius than in the polluted, near-shore subregion,
where free tropospheric temperature is more relevant. This study suggests the
necessity to consider distinct ACI regimes in cloud studies in the southeast
Atlantic.

Abstract. The Cloud Aerosol Lidar and Infrared Pathfinder Satellite
Observations (CALIPSO) mission released version 4.00 of their lidar level 1
data set in April of 2014, and subsequently updated this to version 4.10 in
November of 2016. The primary difference in the newly released version 4
(V4) data is a suite of updated calibration coefficients calculated using
substantially revised calibration algorithms. This paper describes the
revisions to the V4 daytime calibration procedure for the 532 nm parallel
channel. As in earlier releases, the V4 daytime calibration coefficients are
derived by scaling the raw daytime signals to the calibrated nighttime
signals acquired within a calibration transfer region, and thus the new V4
daytime calibration benefits from improvements made to the V4 532 nm
nighttime calibration. The V4 calibration transfer region has been moved
upward from the upper troposphere to the more stable lower stratosphere. The
identification of clear-air columns by an iterative thresholding scheme,
crucial to selecting the observation regions used for calibration, now uses
uncalibrated 1064 nm data rather than recursively using the calibrated 532 nm data, as was done in version 3 (V3). A detailed account of the rationale
and methodology for this new calibration approach is provided, along with
results demonstrating the improvement of this calibration over the previous
version. Extensive validation data acquired by NASA's airborne high spectral
resolution lidar (HSRL) shows that during the daytime the average difference
between collocated CALIPSO and HSRL measurements of 532 nm attenuated
backscatter coefficients is reduced from 3.3 %±3.1 % in V3 to
1.0 %±3.5 % in V4.
Magnetic dipolarizations inside geosynchronous orbit with tailward ions flow
Authors: Sun Xiaoying , Liu Weining William , Duan Suping
Published: November 2018

Abstract. Electromagnetic field and plasma data from the Time History of Events and Macroscale Interactions duringSubstorms (THEMIS) near-Earth probes are used to investigate magnetic dipolarizations inside geosynchronous orbit on 27 August 2014 during an intense substorm with AEmax ~ 1000 nT. THEMIS-D (TH-D) was located inside geosynchronous orbit around midnight in the interval from 09:25 UT to 09:55 UT. During this period two distinct magnetic dipolarizations with tailward ions flow are observed by TH-D. The first one is displayed by magnetic elevation angle increase from 15 degree to 25 degree around 09:30:40 UT. The tailward perpendicular velocity is V⟂x ~ −50 km/s. The second one is presented by the elevation angle increase from 25 degree to 45 degree around 09:36 UT. And the tailward perpendicular velocity is V⟂x ~ −70 km/s. These two significant dipolarizations are accompanied with the sharp increase in the energy flux of energetic electron inside geosynchronous. After 5 min expanding of near-Earth plasma sheet (NEPS), THEMIS-E (TH-E) located outside geosynchronous orbit also detects this tailward expanding plasma sheet with ion flow −150 km/s. The dipolarization propagates tailward with speed −47 km/s, along 2.2 RE distance in the X direction between TH-D and TH-E within 5 min. These dipolarizations with tailward ions flow observed inside geosynchronous orbit indicate new energy transfer path in the inner magnetosphere during substorms.
Geology datasets of North America for use with ice sheet models
Authors: Gowan Evan J. , Niu Lu , Knorr Gregor , Lohmann Gerrit
Published: November 2018

Abstract. The ice-substrate interface is an important boundary condition for ice sheet modelling. The substrate affects the ice sheet by allowing sliding through sediment deformation and accommodating the storage and drainage of subglacial water. We present three datasets with different geological parameters for the region that was covered by the ice sheets in North America, including Greenland and Iceland. The first dataset includes the distribution surficial sediments, which is separated into continuous, discontinuous and predominantly rock categories. The second dataset includes sediment grain size properties, which is divided into three classes: clay, silt and sand, based on the dominant grain size of the glacial sediments. The third dataset is the generalized bedrock geology. We demonstrate the utility of these datasets for governing ice sheet dynamics by using an ice sheet model with a simulation that extends through the last glacial cycle. Changes in ice thickness by up to 40 % relative to a reference simulation happened when the shear friction angle was reduced to account for a weaker substrate. These datasets provide a basis to improve the basal boundary conditions in ice sheet models. Gowan, E. J., Niu, L., Knorr, G., and Lohmann, G., 2018.

Neutral equilibrium and forcing feedbacks in marine ice sheet modelling
Authors: Gladstone Rupert M. , Xia Yuwei , Moore John
Published: November 2018

Abstract. Poor convergence with resolution of ice sheet models when simulating
grounding line migration has been known about for over a decade. However,
some of the associated numerical artefacts
remain absent from the published literature. In the current study we apply a Stokes-flow finite-element marine
ice sheet model to idealised grounding line evolution experiments.
We show that with insufficiently fine model
resolution, a region containing multiple steady-state grounding
line positions exists, with one steady state per node of the model
mesh. This has important implications for the design
of perturbation experiments used to test convergence of grounding
line behaviour with resolution.
Specifically, the design of perturbation experiments can be under-constrained,
potentially leading to a “false positive” result.
In this context a false positive is an experiment that appears
to achieve convergence when in fact the model configuration is
not close to its converged state.
We demonstrate a false positive: an apparently successful
perturbation experiment (i.e. reversibility is shown) for a
model configuration that is not close to a converged solution.
If perturbation experiments are to be used in the future,
experiment design should be modified to provide additional
constraints to the initialisation and spin-up requirements. This region of multiple locally stable steady-state
grounding line positions has previously
been mistakenly described as neutral equilibrium.
This distinction has important implications for understanding
the impacts of discretising a forcing feedback involving
grounding line position and basal friction.
This forcing feedback cannot, in general, exist in a region of
neutral equilibrium and could be the main cause of poor convergence
in grounding line modelling.

Published: November 2018

STEM (Science, Technology, Engineering, and Mathematics) areas are integral content disciplines in all economies. Although most countries have and continue to ensure quality science (S) and Mathematics (M) education for primary (elementary) and secondary school students, the technology (T) and engineering (E) content areas tend not to be regarded as core to national curricula in the same way that science and mathematics are regarded as essential. This article discusses efforts in various countries to better promote and integrate Technology and Engineering Education (TEE) in schools. This paper highlights common themes and argues that we can learn from each other’s efforts in TEE. We argue that dialogue across nations can help us to build international STEM education collaboration networks, better understand the nature of STEM and how to better engage pupils and students in STEM subjects, and work towards gaining inputs to national TEE policy that can leverage positive change.

Melampus: um modelo deep learning para triagem psicológica infantil
Authors: Da Silva Wesley Felipe , Raeder Mateus
Published: November 2018

Embora problemas relacionados à saúde mental usualmente tenham início durante a infância ou adolescência, apenas uma pequena parcela desta população recebe diagnóstico e tratamento adequado. Uma das causas para a baixa taxa de identificação de desordens mentais é a falta de instrumentos especializados nesta tarefa, especialmente ferramentas que reduzam o custo e o tempo necessário para a execução de processos de triagem psicológica. Na literatura recente, muitos autores vêm analisando como o aprendizado de máquina pode contribuir para a construção de instrumentos de avaliação psicológica, contudo poucas pesquisas se propõem a construir ferramentas válidas para grupos compostos majoritariamente por crianças. O presente trabalho propõe um modelo de ferramenta para apoio à triagem psicológica infantil baseada em testes clínicos e deep learning. Tal modelo foi avaliado através de uma implementação que combina o uso de Redes Neurais Convolucionais e um sistema de escalas clínicas para avaliação do Desenho da Figura Humana. Os resultados apresentados pelos modelos de classificação treinados demonstraram bons índices de acerto considerando-se a pequena amostra disponível, o que sugere que ferramentas de deep learning podem ser adequadas para o cenário proposto.

Published: November 2018

Na qualidade de principal agente polinizador, as abelhas são essenciais à produção de alimentos para o ser humano e para manutenção dos ecossistemas. Entre as culturas agrícolas utilizadas para o consumo humano, 75% dependem de polinização. Alinhando-se a uma preocupação atual com a sobrevivência das abelhas, este artigo visa identificar padrões de colônias de Apis mellifera a fim de auxiliar o apicultor no manejo e na manutenção de suas colmeias. Nosso método consistiu na aplicação de uma técnica de clusterização em dois datasets reais de colmeias em clima temperado com dados de temperatura, umidade e massa. Foram utilizados três datasets do portal HiveTool.net; dois deles divididos em período frio (outono e inverno) e período quente (primavera e verão) e o terceiro, para efeito comparativo, dividido em períodos mesclando estações frias e quentes: inverno e primavera, e verão e outono. A partir da aplicação do índice Calinski-Harabasz e do algoritmo K-means, identificamos padrões coerentes e associados às transições entre as estações do ano. Além disso, pudemos concluir que a colônia mais forte é mais eficiente ao tentar manter o microclima da colmeia durante o inverno.

FEMINISMO E EMPODERAMENTO DA MULHER NA SOCIEDADE BRASILEIRA
Authors: Moura Matias Wédja Roberta
Published: November 2018

Este estudo tem por objetivo trabalhar a história do movimento feminista no Brasil, com elementos que envolvam subsídios de empoderamento e descrevê-los através de uma ótica feminista. A partir de uma abordagem embasada no estudo da história das mulheres, enfatizamos através de pesquisa bibliográfica e estudo de imagens virtuais, uma discussão acerca do lugar social, muitas vezes marginalizado, que a mulher ocupa no Brasil e a oferta crescente de entendimento sobre seus próprios direitos. Escolheu-se analisar também a rede social Facebook, mais especificamente suas “comunidades” feministas, (devido ao grande nível de alcance desta ferramenta em várias faixas etárias e em diferentes grupos sociais) por considerarmos que proporcionam auxílio na problematização e disseminação do movimento feminista e suas possíveis perspectivas do conceito de empoderamento feminino.

Paradoxos e ambiguidades na ideia de interdisciplinaridade
Authors: Raynaut Claude
Published: November 2018

A prática da interdisciplinaridade nos coloca diante de um paradoxo: embora a ideia que a inspira ainda nos pareça pioneira, ela não tem nada de efetivamente novo. Apareceu há quase um século e desde então nunca deixou de ser aprofundada e aplicada em vários contextos da pesquisa e do ensino. No entanto, apesar de seu aparente sucesso, o projeto de ultrapassagem do quadro disciplinar continua a ser objeto de múltiplas controvérsias e resistências. Quais as razões das difculdades que essa visão inovadora da prática científca encontra para alcançar um pleno reconhecimento no quadro acadêmico? Em primeiro lugar, há de constatarmos que, como qualquer outra forma de inovação, ela é percebida como ameaça por instituições e atores sociais que se benefciam da estabilidade de quadros organizacionais estabelecidos e que impõem resistências a toda perspectiva de mudança. Contudo, além dessa blocagem de cunho político – no sentido amplo da palavra – existem também razões mais essenciais, de caráter conceitual e epistemológico, ligadas à confusão que geram a multiplicidade e a heterogeneidade das interpretações da noção e dos conteúdos a ela atribuídos. É esse caráter heterogêneo do pensamento interdisciplinar que gostaria de explorar aqui. Para isso, proponho que, em um primeiro momento, nós nos interroguemos sobre a própria noção de disciplina e sobre a dinâmica de redefnições, de trocas de conceitos e métodos, de passagem de fronteiras, intrínseca ao recorte disciplinar. O primeiro passo para clarifcar a ideia interdisciplinar consiste em abster-se de confundi-la com esse movimento constitutivo da vida das disciplinas. Em segundo lugar, se o projeto interdisciplinar se defne como esforço para ultrapassar essa dinâmica espontânea das disciplinas e construir algo novo no domínio da produção e da transmissão do conhecimento, quais as características e os objetivos dessa tentativa original para ambiguidades na ideia de interdisciplinariedade dar conta da complexidade e da hibridização do mundo real? Aqui diversas são as metas almejadas, múltiplos os caminhos seguidos e dispares os públicos visados pelos projetos que se reclamam da interdisciplinaridade. Tal diversidade não é um problema em si. Entretanto, torna-se problemática quando a confusão reina, bem como as nuanças e divergências não são sufcientemente explicitadas, clarifcadas, articuladas. Nesse caso, surge uma incoerência que prejudica a elaboração de uma estratégia institucional comum necessária para combater as falsas interpretações, os preconceitos, as resistências que até hoje impedem que a abordagem seja integrada de modo duradouro e incontestável nas instituições científcas acadêmicas. É esse trabalho de identifcação e clarifcação da diversidade e das ambiguidades da interpretação da prática interdisciplinar que procurei iniciar nesse texto.

Neste artigo, busca-se fazer um balanço histórico do Programa de Pós-Graduação em Meio Ambiente e Desenvolvimento (PPGMADE) da UFPR, a partir da apresentação do contexto filosófico, geopolítico e institucional em que emerge uma nova modalidade de produção interdisciplinar do conhecimento acadêmico-científico. Para tanto, buscou-se identificar os fundamentos críticos de outra proposta epistemológica, em que são produzidos as metodologias e os procedimentos de pesquisa, cujo resultado é expresso nos seguintes elementos: concepções de sociedade e natureza; práticas interdisciplinares; limites e desafios para a resolução dos problemas socioambientais; e novos desafios epistemológicos, políticos e institucionais para a construção de uma ciência pública, cidadã e pertinente.
Aspectos do perfil dos egressos do PPGMADE em 22 anos e o efeito multiplicador da formação dos Doutores
Authors: Lima Cristina De Araújo , Fortunato Rafaela Antunes
Published: November 2018

O presente artigo tem o objetivo de analisar o perfil dos egressos do Programa de Pós-Graduação em Meio Ambiente e Desenvolvimento da Universidade Federal do Paraná - UFPR – PPGMADE - em 22 anos, refletindo a respeito do seu efeito multiplicador na formação de doutores. O método utilizado é a matriz de correlações, utilizando como fonte de pesquisa os dados coletados no PPGMADE e também na Plataforma Lattes, do CNPq. Tem-se, como pressuposto, que a maioria dos doutores formados pelo PPGMADE tem atuação na docência, o que permite uma ampliação de suas pesquisas dentro do ambiente acadêmico, redistribuindo os saberes e oportunidades para os seus alunos. Constatou-se que grande parte dos doutores “madeanos” (oriundos do PPGMADE) continuam atuando em suas áreas de pesquisa – sendo que, destes, 84,33% são professores universitários; líderes e/ou participantes de grupos de pesquisa; realizadores de projetos de extensão junto a comunidades; formadores de opinião e continuam publicando suas pesquisas em periódicos científicos, eventos, mídia, capítulos de livros e livros. Além disso, 48,23% das formações do PPGMADE são de mulheres, o que mostra um avanço para uma situação mais equilibrada entre gêneros nesse âmbito de ensino.

Indigenous students: Barriers and success strategies-A review of existing literature
Authors: Nelson Heather Joyce , Cox-White Twana Lee-Ann , Ziefflie Beverlee Ann
Published: November 2018

There are many factors that effect the post-secondary completion rate of Indigenous students. The Indigenous student completion rate is a reflection of the number of students entering post-secondary education but is significantly affected by withdrawal rates (institutional withdrawals and student voluntary withdrawals). In the Saskatchewan Polytechnic School of Nursing, the Indigenous student withdrawal rate was 4.2% higher than the total nursing student population. Lower success rates among Indigenous students is a concerning issue in nursing programs. Continuing to operate programs and teach in the same fashion is not improving success rates. The Truth and Reconciliation Commission of Canada: Calls to Action (2012) highlighted the need to examine strategies and develop policies to enhance Indigenous student success. To this end, recent literature was reviewed to determine trends among Indigenous nursing students, their struggles, and more importantly, the successful strategies currently being implemented. Indigenous peoples are not a homogenous group; rather, they are a mosaic of cultures, languages and nations. The authors examined the literature to determine key factors that enabled or prevented the success of post-secondary Indigenous students. Twenty-one articles on current research regarding Indigenous student success facilitators and barriers were examined. These articles encompassed research from Canada, the United States, Australia and New Zealand. The purpose of this literature review was to identify themes and gaps, drive positive change in education, and guide future research. The research team found four common themes: academic preparedness, cultural safety, intrinsic student factors, and student support.

Published: November 2018

This paper intends to examine the efficacy of song education to develop English proficiency in China’s EFL context. By conducting a comparative study between two parallel classes and analyzing the results of forty-eight questionnaires, the paper reveals the following: 1) song education can help improve pronunciation and intonation skills to a great extent; 2) only carefully selected songs can be evidently helpful with the acquisition of vocabulary and grammar; and 3) song education makes it possible for students to be more culturally informed and culturally interested. Thus this paper casts some light on how song education can be employed as an effective strategy to develop English proficiency for English majors in China.
Potential Risks and Their Analysis of the Apparel & Textile Industry in Turkey: A Quality-Oriented Sustainability Approach
Authors: Erdil Ayşenur , Taçgın Erturul
Published: November 2018

The most significant issues in businesses within the scope of manufacturing and services are the sustainability of production quality, setting quality standards and reducing the waste amount during the manufacturing process. From this point of view, the aim of this study is to provide a better quality level of supplying households’ apparel needs while reducing the environmental, economic and social problems of the sustainable supply chain of the apparel sector and extending the lifecycle of apparel. The importance of risk analyses and calculations in the applications of industrial sectors plays a vital role in evaluating the factors of sustainability dimensions. In order to address this risk analysis in this research, quality-oriented implementations are applied to determine the failure modes and effect analysis (FMEA). The significant factors are determined via Pareto Analysis (PA) to control and prevent potential errors and failures in the manufacturing systems of the textile industry. To achieve the aim of this study, the methodology of the research focuses on discovering failures of negative impact based on the primary factor degrees with the computing of risk priority numbers (RPNs) in the manufacturing process of the textile-apparel industry in Turkey. According to the ranking of the RPNs, FMEA application and PA enable to decrease the effects of negative factors and risks as well as the waste amount of the apparel-textile industry, as well as to increase the lifecycle of apparel and products.

In shipbuilding, forming plate by line heating is atypical complex manufacturing process involving many uncertain factors, so it is difficult to establish an accurate mathematical model. How to establish a knowledge model that can reflect technological laws is the key to the development of an intelligent decision system for forming plate by line heating. In this article, rough set (RS) theory is applied to the modeling of the line heating process. By defining variable-inclusion RSs, an algorithm of knowledge reduction is proposed, which enhances the noise immunity and fault tolerance of the model, and improves the efficiency of knowledge acquisition. Through introducing fuzzy logic, a method of modeling the line heating process based on RSs and fuzzy logic is proposed, which effectively extracts the technological rules of plate formation. Finally, rapid decision-making for process parameters is implemented by fuzzy inference technology.

1. Introduction

For some complex manufacturing technologies in modern shipbuilding, such as line heating and welding processes, it is difficult to establish an exact mathematical model because of high nonlinearity, multivariable coupling, and uncertainties of the system. With the development of computer technology and artificial intelligence, soft computing methods such as artificial neural networks, genetic algorithms, fuzzy logic, and rough set (RS) theory have been applied successively in ship manufacturing process modeling, which shows good prospects for intelligent technology in shipbuilding. Shin et al. (1999) at Seoul National University used a single-curvature plate model to simulate the formation of saddle-type shells and deduce the technological parameters of line heating by an artificial neural network. They also proposed a comprehensive algorithm for automatically curving plate by line heating, and further developed an application system that can simulate the deformation of double-curved plates (Shin et al. 2004a, 2004b). Liu et al. (2006) applied a hierarchical genetic algorithm to optimize the technological parameters of an automatic line heating process. In the field of ship welding, fuzzy logic technology has been used to establish a fuzzy model of the relationship between welding variables and weld forming-parameters (Su 2009). Feng (2012) set up a knowledge base of a ship-welding process by a RS method and then implemented ship-welding production design through uncertainty reasoning. Based on RS theory, Chen and Lv (2013) developed a data-driven knowledge base for quality control of ship hull welding.

Igennem de seneste fire år har der opholdt sig minimum 52.500 østeuropæiske EU-borgere i Danmark, heraf cirka halvdelen fra Polen. Sammen med den gradvise udfasning af Østaftalen fra 2006/8 samt ophævelsen af fagforeningernes eksklusivaftaler i 2006 har denne udvikling skabt en ny situation på det danske arbejdsmarked. Migrantarbejderne fra de nye EU-lande er karakteriseret ved høj grad af fleksibilitet, mobilitet og villighed til at arbejde, dårligere socio- økonomiske forhold og arbejdsmæssige vilkår i deres hjemlande samt en anden kulturel bag- grund end deres danske kolleger. Denne artikel giver et indblik i nogle af konsekvenserne ved arbejdsmigration fra de nye EU-lande på det (u)faglærte danske arbejdsmarked belyst ud fra en analyse af henholdsvis et politisk, et fagforenings-, et brancheorganisations, et virksomheds- ejer-, et arbejdsleder- og et medarbejderperspektiv.
Hovell and Lamprecht
Authors: Wood Ian
Published: November 2018

In the early years of the twentieth century, Professor Karl Lamprecht was a
powerful and controversial figure in German academia, offering a universal
interpretation of history that drew on an eclectic mix of politics, economics,
anthropology and psychology. This article explores Mark Hovell’s
experiences of working with Lamprecht at the Institut für Kultur- und
Universalgeschichte [Institute for Cultural and Universal History] in Leipzig
between 1912 and 1913, while also situating Hovell’s criticisms of the
Lamprechtian method within wider contemporary assessments of Lamprecht’s
scholarship.
A needle in a haystack: Mesozoic origin of parasitism in Strepsiptera revealed by first definite Cretaceous primary larva (Insecta)

Published: November 2018

Twisted winged insects (Strepsiptera) are a highly specialized small order of parasitic insects. Whether parasitism developed at an early or late stage in the evolution of the group was unknown. Here we record and describe the first definite Mesozoic strepsipteran primary larva embedded in Burmese amber (∼99 million years ago). This extends the origin of parasitism back by at least ∼50 million years, and reveals that this specialized life style has evolved in the Mesozoic or even earlier in the group. The extremely small first instar displays all diagnostic characters of strepsipteran immatures of this stage and is nearly identical with those of Mengenillidae, one of the most “ancestral” extant strepsipteran taxa. This demonstrates a remarkable evolutionary stasis over  100 million years. The new finding strongly weakens the case of small larvae embedded in Cretaceous amber interpreted as strepsipteran immatures. They differ in many structural features from extant strepsipteran primary larvae and are very likely parasitic beetle larvae.
Highly Bendable Piezoelectric Resonators for Flexible Radio‐Frequency Electronics

Published: November 2018

As bendable, conformal electronic components, flexible gigahertz resonators are in demand as important building blocks (e.g., oscillators, filters, and signal processors) in future flexible radio‐frequency electronics for efficient wireless communication. Here, a 2.7 GHz piezoelectric thin‐film resonator (i.e., film bulk acoustic wave resonator) is presented that possesses high levels of both electrical performance and mechanical flexibility. The highly bendable resonator fabricated by FlexMEMS technology is essentially a thin‐film composite (i.e., high‐quality metal and inorganic piezoelectric layer stacks) encapsulated in polymer thin films with a total thickness of only 11.6 µm. The experimental series resonance frequency (fS), parallel resonance frequency (fP), quality factor (Q), and effective coupling coefficient () are 2.72 GHz, 2.77 GHz, 1398, and 4.39%, respectively. These parameter values are comparable to those of a conventional silicon‐based resonator. The minimum bending radius of the flexible resonator can be reduced to ≈0.5 mm with very slight electrical performance variation. Furthermore, the flexible resonator retains its mechanical and electrical stability after 2000 bending cycles. The superior mechanical flexibility and stability represent a significant advancement toward bendable, foldable, and conformal electronics working in the RF range.
Fast and furious: A neglected issue in health promotion among young drivers
Authors: Oviedo‐Trespalacios Oscar , Scott‐Parker Bridie
Published: November 2018

Issues addressed

This paper investigates the influence of mood while driving, advocates for identifying high‐risk groups and detects associations between mood while driving and risky driving behaviours. While commensurate studies regarding aggressive driving have confirmed significant detriments in driving performance, little scholarly research has studied the gaps and opportunities at the intersection of mood and risky driving in young drivers.

Methods

A cross‐sectional design was implemented using 660 young drivers (17‐25 years) from Australia (34.7%) and Colombia (65.3%), who completed the Behaviour of Young Novice Drivers Scale (BYNDS). Cluster analysis differentiated young drivers across two groups: high‐risk and low‐risk driving while influenced by mood. Hierarchical segmentation analysis explored the relationship between driver mood and self‐reported risky driving behaviour.

Results

Young drivers reported frequent driving while influenced by mood. The typical risky driving behaviours of young drivers who are emotion‐affected are transient violations (eg, speeding) and risky exposure (eg, driving tired).

Conclusions

Risky driving behaviours that have been found to increase the risk of road injury (speeding, fatigued driving) and to decrease the survivability of road crashes (speeding) are inextricably intertwined with the influence of driver mood upon driving behaviour at an international level. Driver mood is a neglected issue in health promotion programs for young drivers.

So what?

Current health promotion interventions for young drivers safety such as Graduated Driver Licensing may not prevent driving while influenced by mood. Additional strategies are required to minimise the exposure to driving while affected by negative mood.

Background

Esthesioneuroblastoma (ENB) is a rare neuroendocrine tumor. The purpose of this study was to compare the Kadish, tumor‐node‐metastasis (TNM), and Dulguerov's modified TNM staging in order to determine the impact of the stage on primary surgical treatment selection, margin status, and survival.

Methods

The National Cancer Database (NCDB) was used to identify patients diagnosed with ENB between 2004 to 2015. Patients were excluded based on the ability to properly stage their disease as well as the availability of treatment data.

Results

Eight‐hundred eighty‐three patients had sufficient data for analysis. On multivariate analysis, age and government insurance were associated with primary surgical treatment, whereas tumor stage, gender, race, hospital type and volume, and comorbidity score were not. Age, charlson‐deyo comorbidity (CDCC) score, hospital volume, and nodal status were found to be predictors of survival. Multivariate‐analysis controlling for stage failed to demonstrate clear survival differences between staging in both TNM and Kadish systems. T‐stage and the presence of regional nodal metastasis were associated with an increased risk of positive margins on multivariate analysis.

Conclusion

Although primary surgical management and positive margins can be predicted by certain patient and tumor factors, clinical staging systems for ENB poorly predict prognosis over a 10‐year horizon.
