Wind turbine wake measurements with automatically adjusting scanning trajectories in a multi-Doppler lidar setup
Authors: Wildmann Norman , Vasiljevic Nikola , Gerz Thomas 
Published: June 2018

Abstract. In the context of the Perdigão 2017 experiment, the German Aerospace
Center (DLR) deployed three long-range scanning Doppler lidars with the dedicated
purpose of investigating the wake of a single wind turbine at the
experimental site. A novel method was tested for the first time to
investigate wake properties with ground-based lidars over a wide range of
wind directions. For this method, the three lidars, which were space- and
time-synchronized using the WindScanner software, were programmed to measure
with crossing beams at individual points up to 10 rotor diameters downstream
of the wind turbine. Every half hour, the measurement points were adapted to the
current wind direction to obtain a high availability of wake measurements in
changing wind conditions. The linearly independent radial velocities where
the lidar beams intersect allow the calculation of the wind vector at those
points. Two approaches to estimating the prevailing wind direction were tested
throughout the campaign. In the first approach, velocity azimuth display (VAD) scans of one of the
lidars were used to calculate a 5 min average of wind speed and wind
direction every half hour, whereas later in the experiment 5 min
averages of sonic anemometer measurements of a meteorological mast close to
the wind turbine became available in real time and were used for the scanning
adjustment. Results of wind speed deficit measurements are presented for two
measurement days with varying northwesterly winds, and it is evaluated how
well the lidar beam intersection points match the actual wake location. The
new method allowed wake measurements to be obtained over the whole measurement
period, whereas a static scanning setup would only have captured short
periods of wake occurrences.
The temporally varying roles of rainfall, snowmelt and soil moisture for debris flow initiation in a snow-dominated system

Published: June 2018

Abstract. Debris flows represent frequent hazards
in mountain regions. Though significant effort has been made to predict such
events, the trigger conditions as well as the hydrologic disposition of a
watershed at the time of debris flow occurrence are not well understood.
Traditional intensity-duration threshold techniques to establish trigger
conditions generally do not account for distinct influences of rainfall,
snowmelt, and antecedent moisture. To improve our knowledge on the connection
between debris flow initiation and the hydrologic system at a regional scale,
this study explores the use of a semi-distributed conceptual rainfall–runoff
model, linking different system variables such as soil moisture, snowmelt, or
runoff with documented debris flow events in the inner Pitztal watershed,
Austria. The model was run on a daily basis between 1953 and 2012. Analysing
a range of modelled system state and flux variables at days on which debris
flows occurred, three distinct dominant trigger mechanisms could be clearly
identified. While the results suggest that for 68 % (17 out of 25) of the
observed debris flow events during the study period high-intensity rainfall
was the dominant trigger, snowmelt was identified as the dominant trigger for
24 % (6 out of 25) of the observed debris flow events. In addition,
8 % (2 out of 25) of the debris flow events could be attributed to the
combined effects of low-intensity, long-lasting rainfall and transient
storage of this water, causing elevated antecedent soil moisture conditions.
The results also suggest a relatively clear temporal separation between the
distinct trigger mechanisms, with high-intensity rainfall as a trigger being
limited to mid- and late summer. The dominant trigger in late spring/early
summer is snowmelt. Based on the discrimination between different modelled
system states and fluxes and, more specifically, their temporally varying
importance relative to each other, this exploratory study demonstrates that
already the use of a relatively simple hydrological model can prove useful to
gain some more insight into the importance of distinct debris flow trigger
mechanisms. This highlights in particular the relevance of snowmelt
contributions and the switch between mechanisms during early to mid-summer in
snow-dominated systems.
Aproximações entre o livro e o jornal: a tradição do rodapé literário na imprensa paulistana na década de 1940
Authors: Nunes Mônica Rodrigues 
Published: June 2018

O rodapé de crítica literária, adotado pelos grandes jornais brasileiros por influência francesa, teve seu auge no decênio de 1940, quando quase todos os jornais paulistanos mantinham uma rubrica no pé da página. Com objetivo de entender como se configuravam estes espaços, o corpus de análise selecionado para este estudo circunscreveu-se aos rodapés publicados por três jornais paulistanos de grande circulação e prestígio: Folha da Manhã, Correio Paulistano e O Estado de S. Paulo. Amparado em pesquisa bibliográfica e qualitativa, este texto aponta que os rodapés de crítica literária, feitos, em quase sua totalidade, por homens de letras, se apresentavam como um espaço que marcava o desenvolvimento das obras, os rumos do mercado editorial, as tendências literárias e artísticas, relatos de experiência e, em menor grau, de debate político.
DESENCONTROS ENCONTRADOS: ESTUDO DO CONTO "O GRAVADOR", DE RUBEM FONSECA, À LUZ DE TEORIAS DA FICÇÃO
Authors: Bueno Raquel Illescas , Gebra Fernando De Moraes 
Published: June 2018

No curso Teoria da Ficção, da Pós-Graduação da Universidade Federal do Paraná, buscamos a aplicabilidade das teorias da ficção, analisando suas metodologias e o discurso sobre seus métodos. Propomos, aqui, uma análise de “O gravador”, conto publicado no livro A coleira do cão, de 1965. Essa narrativa é exemplar da habilidade de Rubem Fonseca em montar enredos engenhosos, sem descuidar da densidade na abordagem temática. Em contos dessa natureza, a atenção do leitor naturalmente fica dividida entre o apelo da intriga, a observação da técnica pela qual o fio narrativo é estabelecido no discurso e a reflexão sobre questões importantes da vida social. Nossa proposta de análise visa a possibilitar o encontro de algumas das teorias da ficção a fim de verificar em que medida elas apresentam, com todas suas particularidades, pontos de intersecção para a análise de narrativas breves da literatura brasileira.
Sexuální zdrženlivost a celibátní praxe v náboženstvích světa
Authors: Bártová Věra 
Published: June 2018

Celibát je v dnešní době v našich zeměpisných šířkách centrální Evropy neodmyslitelně spjat s římskokatolickou církví. V této církvi je velmi diskutovaným tématem ve spojitosti s kněžími a to nejen v posledních letech, jak by se mohlo zdát. Diskuze a boje v otázce povinnosti či dobrovolnosti celibátu kléru se vedou napříč historií celého křesťanství. Křesťanství však není jediným světovým náboženstvím se zavedenou institucí celibátu. Celibátní praxe je běžná i v buddhismu a také se s ní lze setkat v hinduismu. Naopak judaismus a islám se k celibátu staví odmítavě, přesto i v nich se v průběhu historie objevuje určitá jeho forma. Každé náboženství má také snahu určitým způsobem usměrňovat sexuální chování svých vyznavačů, jedním z prostředků je i sexuální zdrženlivost. Přestože se mnoho studií věnuje náboženství a sexualitě z nejrůznějších perspektiv, vztah náboženství, celibátu a sexuální zdrženlivosti bývá často opomíjen a zmiňován pouze okrajově. Tato studie se proto snaží přinést základní přehled vztahu světových náboženství k sexuální zdrženlivosti a celibátu.

In the present study, with mixed methodology and a population size of 280 participants, we attempted to replicate these results by operationalizing SSC in the two following manners: (a) through experimental manipulation --randomly requesting that participants compare themselves with those who are above or below them in a social hierarchy scale-- and (b) through measuring SSC as individual difference. The results show no effects due to experimental manipulation, but do support that SSC, measured as individual difference, positively correlates with general self-efficacy. Regarding qualitative analysis, when the participant’s descriptions of common characteristics in members of the upper and lower class were studied, we found that situational characteristics predominated (over dispositional characteristics), but with greater positive valence when describing the upper class. We conclude that SSC is an important factor in self-efficacy and that it moderates effects of social comparison.</strong></span>

Published: June 2018

<p>Meta-analysis is an essential methodology that allows researchers to synthesize the scientific evidence available on a given research question. Due to its wide applicability in most applied research fields, it is really important that meta-analyses be written and reported appropriately. In this paper we propose some guidelines to report the results of a meta-analysis in a scientific journal as Annals of Psychology. Concretely, the structure for reporting a meta-analysis following its different stages is detailed. In addition, some recommendations related to the usual tasks when conducting a meta-analysis are provided. A recent meta-analysis focused on the psychological field is used to illustrate the guidelines proposed. Finally, some concluding remarks are presented. </p>
Utilisation de stimulants du système nerveux central chez les élèves du primaire suivis à l’école pour des troubles du comportement
Authors: Lapalme Mélanie , Temcheff Caroline , Boutin Stéphanie , Déry Michèle 
Published: June 2018

Les élèves du primaire référés aux services scolaires complémentaires pour des troubles du comportement constituent l’une des clientèles les plus visées par la prescription de stimulants du système nerveux central (SSNC) puisque nombre d’entre eux présentent un TDAH. Il existe cependant très peu d’information permettant d’établir jusqu’à quel point la prise de SSNC est associée au TDAH chez ces élèves ou si d’autres caractéristiques contribuent à accroître la probabilité d’utilisation des SSNC. L’étude a été menée auprès de 341 élèves suivis à l’école primaire pour des troubles du comportent (27,8 % de filles, âge moyen : 9,9 ans). Les symptômes du TDAH et d’autres troubles du comportement ont été évalués à l’aide d’un instrument diagnostique utilisé auprès d’un parent et d’un enseignant. L’étude montre que 39,9 % des élèves prennent des SSNC et que, parmi les élèves qui n’ont pas de TDAH, près du tiers utilisent des stimulants. Les symptômes d’hyperactivité-impulsivité, les symptômes de trouble de l’opposition avec provocation, le groupe d’âge (6-8 ans), le statut socioéconomique (moyen-élevé) et le placement en classe spécial contribuent de manière unique à accroître la probabilité d’utiliser des SSNC. Ces résultats suggèrent donc que plusieurs caractéristiques autres que le TDAH peuvent jouer dans la décision de traiter les difficultés de ces enfants avec des SSNC. Ces résultats appellent à une meilleure évaluation du TDAH chez ces enfants de même qu’à un suivi longitudinal pour connaître les effets à long terme des SSNC sur leur adaptation scolaire.

ObjectiveTo identify behavioral health provider perspectives on gaps in mental health care for youth with rheumatologic conditions.MethodsSocial workers (n = 34) and psychologists (n = 8) at pediatric rheumatology centers in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) completed an online survey assessing current practices and mental health care needs of youth with rheumatologic conditions. Responses were compared to a published survey of CARRA rheumatologists (n = 119). Thematic analysis of 20 semi‐structured interviews with behavioral health providers was performed.ResultsOne‐third of CARRA centers (n = 100) had no affiliated social worker or psychologist. Only 1 behavioral health provider reported current universal mental health screening at their rheumatology clinic, yet routine depression screening was supported by >85% of behavioral health providers and rheumatologists. Support for anxiety screening was higher among behavioral health providers (90% versus 65%; P < 0.01). Interviews illustrated a need for interventions addressing illness‐related anxiety, adjustment/coping/distress, transition, parent/caregiver mental health, and peer support. Limited resources, lack of protocols, and patient cost/time burden were the most frequent barriers to intervention. Inadequate follow‐up of mental health referrals was indicated by 52% of providers. More behavioral health providers than rheumatologists favored mental health services in rheumatology settings (55% versus 19%; P < 0.01). Only 7 social workers (21%) provided counseling/therapy, and interviews indicated their perceived underutilization of these services.ConclusionBehavioral health providers indicated an unmet need for mental health interventions that address illness‐related issues affecting youth with rheumatologic conditions. Implementation of mental health protocols and optimizing utilization of social workers may improve mental health care for these youth.

Published: June 2018

ObjectiveIn this proof‐of‐concept study, we sought to evaluate whether a value clarification tool enabling patients to view a set of rheumatoid arthritis (RA) treatment preference phenotypes could be used to support shared decision‐making at the point‐of‐care.MethodsWe conducted a pretest/post test study. English‐speaking patients with RA presenting to their scheduled outpatient visits were asked to participate. Visits for patients with active RA were transcribed. Shared decision‐making components were measured using a quantitative coding scheme based on an established model of shared decision‐making.ResultsForty‐six visits were included in the pretest and 40 in the post test phases. Providers offered more disease‐modifying antirheumatic drugs (DMARDs) (2 or more) in the post test visits (60%) compared to the pretest visits (47.8%). Overall, more patients vocalized their values and/or preferences in the post test visits compared to the pretest visits for treatment escalation decisions including a choice of 1 new DMARD (90.9% versus 56.3%), 2 or more new DMARDs (95.8% versus 86.4%), as well as prednisone (87.5% versus 66.7%). Providers were also more likely to base their recommendations on patients’ values and/or preferences in the post test (100% of 6 visits) than the pretest (64.3% of 14 visits) phases during visits in which a recommendation was made. The mean ± SD length of the visit was 29.9 ± 11.6 minutes and 25.1 ± 10.7 minutes in the pretest and post test phases, respectively.ConclusionThis study provides an early indication that a value clarification tool allowing patients to consider a set of preference phenotypes can support shared decision‐making at the point‐of‐care without extending visit time.
Over 16.7% Efficiency Organic‐Silicon Heterojunction Solar Cells with Solution‐Processed Dopant‐Free Contacts for Both Polarities

Published: June 2018

AbstractRealization of synchronous improvement in optical management and electrical engineering is necessary to achieve high‐performance photovoltaic device. However, inherent challenges are faced in organic‐silicon heterojunction solar cells (HSCs) due to the poor contact property of polymer on structured silicon surface. Herein, a remarkable efficiency boost from 12.6% to over 16.7% in poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate)/n‐silicon (PEDOT:PSS/n‐Si) HSCs by independent optimization of hole‐/electron‐selective contacts only relying on solution‐based processes is realized. A bilayer PEDOT:PSS film with different functionalizations is utilized to synchronously realize conformal contact and effective carrier collection on textured Si surface, making the photogenerated carriers be well separated at heterojunction interface. Meanwhile, fullerene derivative is used as electron‐transporting layer at the rear n‐Si/Al interface to reduce the contact barrier. The study of carriers' transport and independent optimization on separately contacted layers may lead to an effective and simplified path to fabricate high‐performance organic‐silicon heterojunction devices.

AbstractA water‐soluble, positively charged polymer is obtained by copolymerizing chitosan with hypromellose, and the evaluation of its biocompatibility and the capacity for the loading of exogenous agents is performed. Films based on hypromellose grafted chitosan (HGC) are employed as a matrix to fabricate composite films by dehydration‐triggered aggregation of copper nanoclusters (NCs). The resulting HGC/Cu NC films are transparent and exhibit an aggregation‐induced emission enhancement of copper NCs, with a resulting photoluminescence quantum yield of 42%. The application of these orange emitting films as color converters for fabrication of remote light‐emitting devices is demonstrated.
Solvent‐Controlled Assembly of Aromatic Glutamic Dendrimers for Efficient Luminescent Color Conversion

Published: June 2018

AbstractA binary supramolecular system where self‐sorting and coassembly behavior can be switched by changing the solvent polarity is hereby reported. Glutamic dendron is separately conjugated with pyrene and naphthalimide luminophores through an alkyl spacer. The resulting structurally similar building units can self‐assemble into one‐dimensional micro/nanostructures with hexagonal and lamellar packing, respectively. Varying solvents from polar aqueous solution to nonpolar decane is evidenced to profoundly inverse the superchirality and switch self‐sorted assembly to coassembly of the two building blocks. The moisture sensitivity of the naphthalimide moiety is considered the primary driving force for the self‐sorting phenomenon in aqueous solution, resulting in inevitable hydration to repel its stacking with hydrophobic pyrene moiety. On the other hand, the naphthalimide unit can integrate segmentally with the pyrene unit in decane, greatly facilitating the nanofiber growth and supramolecular gel formation along with improved energy transfer efficiency between luminophores. As a result, the coassembly‐based thin films show efficient luminescent color conversion upon the UV light irradiation. This research presents a useful route for the fabrication of controllable solution‐processed light emitting devices from self‐assembled multicomponent systems.

Published: June 2018

AbstractFollowing the ever‐expanding technological demands, printed electronics has shown palpable potential to create new and commercially viable technologies that will benefit from its unique characteristics, such as, large‐area and wide range of substrate compatibility, conformability and low‐cost. Through the last few decades, printed/solution‐processed field‐effect transistors (FETs) and circuits have witnessed immense research efforts, technological growth and increased commercial interests. Although printing of functional inks comprising organic semiconductors has already been initiated in early 1990s, gradually the attention, at least partially, has been shifted to various forms of inorganic semiconductors, starting from metal chalcogenides, oxides, carbon nanotubes and very recently to graphene and other 2D semiconductors. In this review, the entire domain of printable inorganic semiconductors is considered. In fact, thanks to the continuous development of materials/functional inks and novel design/printing strategies, the inorganic printed semiconductor‐based circuits today have reached an operation frequency up to several hundreds of kilohertz with only a few nanosecond time delays at the individual FET/inverter levels; in this regard, often circuits based on hybrid material systems have been found to be advantageous. At the end, a comparison of relative successes of various printable inorganic semiconductor materials, the remaining challenges and the available future opportunities are summarized.
