Análise da Produção bibliográfica internacional sobre Olivoturismo
Authors: Kersanach Kim Wallner , Valduga Vander
Published: July 2020

Com crescimento no cultivo de oliveiras e o consequente aumento o consumo do azeite de oliva, inicia o interesse de consumidores por conhecer seu processo de produção. Essa curiosidade despertada em consumidores gera uma nova modalidade no turismo do país, o chamado olivoturismo, no qual, realizam-se atividades em torno do cultivo das oliveiras e a produção do azeite de oliva. Nos contextos acadêmico e comercial, o tema é um tanto recente e requer investigação, portanto, o problema para a presente pesquisa é: qual a situação atual (2019) da produção bibliográfica internacional sobre o olivoturismo? O presente trabalho se caracteriza como bibliográfico, exploratório, descritivo e qualitativo. O objetivo deste estudo é identificar a produção acadêmica existente em torno do assunto do olivoturismo no mundo. Foi identificado que esta atividade é ascendente e importante para o desenvolvimento rural, preservação cultural, entre outros aspectos. No âmbito acadêmico evidenciou-se a importância da realização de novas pesquisas, acompanhando o desenvolvimento de propriedades com atividade turística relacionada ao azeite de oliva.
Jogos, poemas, fantasias: a posição da criação em Freud
Authors: Souza Pedro Fernandez de
Published: July 2020

Este artigo tenta compreender o papel da poesia em Freud a partir da relação que ela entretém com o processo criativo de um modo geral. Se Freud acaba por aproximar, genética e formalmente, a criação literária dos jogos infantis e das fantasias adultas, a poesia e sua eficácia são quase que reduzidas a uma técnica – que ele, por fim, não consegue capturar com seus conceitos. Assim, numa leitura pormenorizada, não são as semelhanças entre as três classes de produção psíquica que se sobressaem, mas sim essa diferença última e enigmática, importante resíduo proveniente da reflexão freudiana mesma.
Antiguidade e modernidade na Teoria do romance de Georg Lukács
Authors: Kurkdjian Anouch Neves de Oliveira
Published: July 2020

Este artigo orienta-se pelo esforço de esmiuçar as características da contraposição entre mundo antigo e mundo moderno formulada por Lukács em sua obra A teoria do romance. Para esse objetivo, parte-se de uma recuperação de certo debate estético alemão no século XVIII, momento no qual a busca pelos fundamentos da arte moderna leva à formulação do contraste entre uma cultura orgânica e plena de sentido, localizada em uma Grécia mítica, e um mundo cindido e fragmentado, que corresponderia à época moderna. As reflexões de Friedrich Schlegel ganham atenção especial aqui, na medida em que tratam essa contraposição de maneira mais histórica do que as de seus contemporâneos. Em seguida, são apontadas as especificidades da abordagem de Lukács acerca da questão, baseadas em uma apreensão mais atenta aos fundamentos histórico-sociais que envolvem a perda de um sentido unitário para a vida na modernidade. Essa percepção permite a Lukács apontar os limites da solução aventada pelos românticos para a superação do caráter cindido da modernidade.

Anticapital para o século XXI (sobre a metacrise do capitalismo e as possibilidades abertas para a política radical)
Authors: Azmanova Albena , Filho José Ivan Rodrigues de Sousa
Published: July 2020

Tomando o caráter moderado dos protestos sociais recentes como seu ponto de partida, esta análise investiga as democracias liberais em seu estado atual, um estado em que a suposta crise do capitalismo entrou, ela própria, em crise – uma condição social de metacrise, marcada pela ausência de energias utópicas e da prospectiva de uma revolução –, ao mesmo tempo que a sociedade experiencia a si mesma em crise perpétua. Esta investigação apreende, então, o potencial de mudança radical pelo prisma da subversão do capitalismo (e não da derrubada dele ou da resistência a ele) através de práticas que combatam a própria dinâmica constitutiva do capitalismo – a produção de lucro.

Certeza, Filosofia da Psicologia e o Manuscrito 119
Authors: Oliveira Wagner Teles de
Published: July 2020

É comum aos textos de Wittgenstein que tratam da certeza e da filosofia da psicologia, produzidos entre 1945 e 1951, a compreensão de que a certeza, essencial ao funcionamento das práticas simbólicas e não simbólicas, é uma questão de atitude. Essa maneira de entender a certeza tem importância fundamental em sua filosofia da psicologia, pois a objetividade das expressões psicológicas é tramada na dependência dela. A edição em separado dos textos sobre a certeza e da filosofia da psicologia faz parecer tratar-se de tópicos desconectados da obra, encobrindo as conexões conceituais entre eles e, além disso, a história de ambos. A explicitação das conexões entre esses textos permite situá-los na obra de Wittgenstein em continuidade com as Investigações, fazendo ver que têm em comum o desenvolvimento de noções elaboradas no MS 119. Assim, os textos sobre a certeza e a filosofia da psicologia podem passar a ser compreendidos como tendo em comum a noção de certeza, desenvolvida no âmbito da concepção prática do significado, que tem sua origem em textos de 1937.
A questão da essência da ciência em Martin Heidegger
Authors: Pulino Maria Eugênia Zabotto
Published: July 2020

Este artigo pretende discutir a concepção de essência da ciência desenvolvida por Heidegger em Introdução à filosofia – curso ministrado em 1928-1929 na Universidade de Freiburg –, no contexto de sua crítica à filosofia moderna e de seu projeto de ontologia fundamental. Tendo em vista que a análise heideggeriana da ciência é inseparável de sua investigação sobre a existência humana, defenderemos que Heidegger não desenvolve uma filosofia da ciência, ao contrário do que diz parte dos estudiosos de sua obra.

O jornalismo político-ideológico de Otto Karpfen
Authors: Ventura Mauro Souza
Published: July 2020

Análise interpretativa dos textos inéditos publicados por Otto Maria Carpeaux (então Otto Karpfen) no semanário Der Christliche Ständestaat, de Viena. O conjunto dos artigos é parte de uma pesquisa mais ampla sobre os ensaios europeus de Carpeaux, publicados entre 1934 e 1936. Os artigos são analisados a partir das relações entre o ambiente político e sociocultural da Áustria na década de 1930, marcado pela ascensão do nacionalsocialismo de Hitler, e o significado ideológico da atuação jornalística de Karpfen, tendo em vista seu engajamento na luta pela independência da Áustria frente ao Terceiro Reich, a partir de sua filiação ao catolicismo político.

Duas ou três ideias de Carpeaux sobre Machado de Assis: estilo e sociedade
Authors: Gimenez Erwin Torralbo
Published: July 2020

Atento a algumas ideias de Carpeaux sobre o olhar machadiano no arco de três décadas, e pondo em relevo o primeiro e o último escrito desse conjunto – um artigo de 1943, inédito em livro e agora aqui reproduzido, e uma apresentação aos contos do autor, de 1972, quase desconhecida da crítica –, o ensaio procura compreender a visão do intérprete acerca dos nexos que sustentam a dialética entre estilo e sociedade. Ao fim, traz um esboço de análise da narrativa “Galeria póstuma” (de Histórias sem data), na qual Machado, segundo Carpeaux, se autoironiza e reflete o seu próprio processo de desmistificação.
Situação e presença de um crítico austríaco-brasileiro
Authors: Vilhena Guilherme Mazzafera S.
Published: July 2020

Procura-se apresentar a vida e obra de Carpeaux, privilegiando sua atuação como crítico literário radicado no Brasil por meio da recuperação de dois ensaios fundamentais de seu percurso, compostos em momentos distintos: “Situação e presença: algumas reflexões sobre a crítica literária” (1941) e “Dialética da literatura brasileira” (1967). Destaca-se a noção de presença, vinculada ao perfil ensaístico de sua escrita, a construção de um locus crítico movente entre a formação europeia e a fruição analítica da literatura brasileira, e a fluida coexistência entre política e literatura em seus escritos.

Guerra Sino-Soviética de 1969: a relação entre os conflitos externos da China e os seus impasses políticos internos
Authors: Santos Isabella Santana dos
Published: July 2020

Este artigo busca compreender os motivos políticos endógenos que resultaram no conflito sino-soviético de 1969 e, a partir disso, refletir sobre as relações entre a política interna e as guerras externas que envolveram a China Maoista, bem como conhecer o papel da guerra externa como solução do impasse político interno. Para desenvolver o tema proposto, esse artigo analisa como as disputas territoriais e as divergências ideológicas, culturais e militares entre China e União Soviética influíram no conflito entre esses dois países. Além disso, também procura-se entender o impacto da Revolução Cultural Chinesa e da luta de Mao Tsé-Tung contra o revisionismo no conflito sino-soviético. Por fim, pretende-se tratar, brevemente, do papel dos armamentos nucleares e discutir o quanto eles influenciaram na dissuasão dessa guerra. Ou seja, serão estabelecidas relações entre os conflitos internos e externos buscando verificar qual o peso de cada um desses fatores para a eclosão da Guerra Sino-Soviética em 1969.
A Poesia Chinesa Definida por Ezra Pound: uma busca pela origem
Authors: Sá Raquel Harumi de
Published: July 2020

O presente texto apresenta uma reflexão a respeito de uma possível “zona de contato” entre as teorias de tradução poética definidas por Ernest Fenollosa e seu discípulo Ezra Pound, e a literatura em língua chinesa por eles traduzida. Elaborado por Mary Pratt (1991), estudiosa de literatura espanhola, o conceito de zonas de contato considera a literatura como um espaço social em que culturas diferentes se encontram, confrontam ou mesmo se atracam (“grapple”) em contextos geralmente de relações de poder altamente assimétricas. Ao verificarmos a ausência do reconhecimento deste contato, por parte das teorias poéticas dos autores supracitados, em relação aos questionamentos levantados por sua crítica, passa a ser reconhecido, cada vez mais, por diversos estudiosos, inclusive de literatura americana, a importância em dialogar e absorver o conhecimento produzido por outras áreas, como a sinologia, a filologia, a linguística etc. Quanto a isto, torna-se possível esboçar um distanciamento crítico e histórico em relação aos preceitos formulados pelo modernismo literário americano, junto com uma reflexão mais ampla sobre o fenômeno da linguagem. A partir deste cenário, também pretende-se esboçar uma metodologia capaz de detectar formulações e referências teóricas, de tradução e linguagem, em Pound, que, quando omitidas, asseguram uma noção de equivalência entre o texto traduzido e o original chinês, que igualmente ofuscam a análise das zonas de contato.
Genetically Predicted Blood Pressure Across the Lifespan
Authors: Georgakis Marios K. , Gill Dipender , Malik Rainer , Protogerou Athanase D. , Webb Alastair J.S. , Dichgans Martin
Published: July 2020

Hypertension is the leading risk factor for stroke. Yet, it remains unknown whether blood pressure pulsatility (pulse pressure [PP]) causally affects stroke risk independently of the steady pressure component (mean arterial pressure [MAP]). It is further unknown how the effects of MAP and PP on stroke risk vary with age and stroke cause. Using data from UK Biobank (N=408 228; 38–71 years), we selected genetic variants as instruments for MAP and PP at age ≤55 and >55 years and across age deciles. We applied multivariable Mendelian randomization analyses to explore associations with ischemic stroke, intracerebral hemorrhage, and their subtypes. Higher genetically predicted MAP was associated with higher risk of ischemic stroke and intracerebral hemorrhage across the examined age spectrum. Independent of MAP, higher genetically predicted PP only at age >55 years was further associated with higher risk of ischemic stroke (odds ratio per-SD-increment, 1.23 [95% CI, 1.13–1.34]). Among subtypes, the effect of genetically predicted MAP on large artery stroke was attenuated, whereas the effect of genetically predicted PP was augmented with increasing age. Genetically predicted MAP, but not PP, was associated with small vessel stroke and deep intracerebral hemorrhage homogeneously across age deciles. Neither genetically predicted MAP nor PP were associated with lobar intracerebral hemorrhage. Beyond an effect of high MAP at any age on ischemic and hemorrhagic stroke, our results support an independent causal effect of high PP at older ages on large artery stroke. This finding warrants further investigation for the development of stroke preventive strategies targeting pulsatility in later life.

Published: July 2020

Recent molecular evidence has confirmed that Meiostemon and Quisqualis are embedded in Combretum. While some of the species in the two former genera have already been transferred to Combretum, several combinations are still wanting. New combinations for these species in Combretum are therefore formalised here for taxa of Meiostemon and Quisqualis that had not been formally transferred yet. Additionally, we list recently described taxa that are placed in Combretum subgenus Cacoucia section Quisqualis.
Revision of the Oriental species of Calleida Latreille (sensu lato). Part 1: Introduction, groups of species, and species of six species groups (Coleoptera: Carabidae: Lebiini)
Authors: CASALE ACHILLE , SHI HONGLIANG
Published: July 2020

This revision focuses on the genus Calleida Latreille, 1824 (in the widest sense) in the Oriental Region, previously treated as genus or subgenus Callidiola Jeannel, 1949. In the present contribution, as first part of a series of revisions of the Asiatic Calleida species, we define nine species groups including all known Asiatic species, based on external features and morphological characters of male and female genitalia. A key for the identification of all nine species groups is provided, along with diagnostic characters, included species, geographical distribution, and brief discussion on monophyly and relationships for each species group. In particular, the present contribution deals with species of six small species groups, including eleven species in total, for which keys to all known species, descriptions, distribution maps, habitus images and genitalia illustrations are provided.Five new species are described: Calleida gressittiana Casale & Shi, sp. n. (type locality: Kinabalu, Sabah, Borneo), Calleida puncticollis Shi & Casale, sp. n. (type locality: Zigui, Hubei), Calleida jelineki Casale & Shi, sp. n. (type locality: Coimbatore, India), Calleida viet Casale & Shi, sp. n. (type locality: Vung Tau, Vietnam), Calleida borneensis Shi & Casale, sp. n. (type locality: Sabah, Borneo). Lectotypes for five taxa are designated. One synonymy is newly proposed: Calleida lieftincki Louwerens junior synonym of Calleida corporaali Andrewes, syn. nov.
A new species of Lepidotrigona (Hymenoptera: Apidae) from Thailand with the description of males of L. flavibasis and L. doipaensis and comments on asymmetrical genitalia in bees
Authors: ATTASOPA KORRAWAT , BÄNZIGER HANS , DISAYATHANOOWAT TERD , PACKER LAURENCE
Published: July 2020

We describe Lepidotrigona satun Attasopa and Bänziger new species from southern Thailand based upon associated males and females (workers). The new species is a member of the L. ventralis species group, which is otherwise represented in Thailand only by L. flavibasis and L. doipaensis. We also describe the males of the latter two species, associated with nests from close to their type localities in northern Thailand. Lepidotrigona doipaensis Schwarz and L. flavibasis (Cockerell) had previously often been misidentified as L. ventralis (Smith), a species confirmed only from Borneo. Based upon differences in male morphology, especially of the metasomal sterna, we conclude that the male described from Vietnam by Sakagami (1975) as belonging to L. flavibasis represents an undescribed species. Our findings support previous taxonomic studies that highlight the importance of including males in the differentiation of closely related species of meliponines and their association with workers. The three species whose males we describe have asymmetric penis valves with the asymmetry differentially developed among the three. We compare this genitalic asymmetry with that known from a different apid genus, Tarsalia.

Published: July 2020

Interactions between epitaxial graphene grown on Si- and C-faces were investigated using Raman imaging and tip-enhanced Raman scattering (TERS). In the TERS spectrum, which has a spatial resolution exceeding the diffraction limit, a D band was observed not from graphene surface, but from the edges of the epitaxial graphene ribbons without a buffer layer, which interacts with SiC on the Si-face. In contrast, for a graphene micro-island on the C-face, the D band disappeared even on the edges where the C atoms were arranged in armchair configurations. The disappearance of the edge chirality via combination between the C atoms and SiC on the C-face is responsible for this phenomenon. The TERS signals from the C-face were weaker than those from the Si-face without the buffer layer. On the Si-face with a buffer layer, the graphene TERS signal was hardly observed. TERS enhancement was suppressed by interactions on the edges or by the buffer layer between the SiC and graphene on the C- or Si-face, respectively.
YAP/TAZ Regulate Elevation and Bone Formation of the Mouse Secondary Palate
Authors: Goodwin A.F. , Chen C.P. , Vo N.T. , Bush J.O. , Klein O.D.
Published: July 2020

Clefting of the secondary palate is one of the most common congenital anomalies, and the multiple corrective surgeries that individuals with isolated cleft palate undergo are associated with major costs and morbidities. Secondary palate development is a complex, multistep process that includes the elevation of the palatal shelves from a vertical to horizontal position, a process that is not well understood. The Hippo signaling cascade is a mechanosensory pathway that regulates morphogenesis, homeostasis, and regeneration by controlling cell proliferation, apoptosis, and differentiation, primarily via negative regulation of the downstream effectors, Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ). We deleted Yap/ Taz throughout the palatal shelf mesenchyme as well as specifically in the posterior palatal shelf mesenchyme, using the Osr2Cre and Col2Cre drivers, respectively, which resulted in palatal shelf elevation delay and clefting of the secondary palate. In addition, the deletion resulted in undersized bones of the secondary palate. We next determined downstream targets of YAP/TAZ in the posterior palatal shelves, which included Ibsp and Phex, genes involved in mineralization, and Loxl4, which encodes a lysyl oxidase that catalyzes collagen crosslinking. Ibsp, Phex, and Loxl4 were expressed at decreased levels in the ossification region in the posterior palatal shelf mesenchyme upon deletion of Yap/ Taz. Furthermore, collagen levels were decreased specifically in the same region prior to elevation. Thus, our data suggest that YAP/TAZ may regulate collagen crosslinking in the palatal shelf mesenchyme, thus controlling palatal shelf elevation, as well as mineralization of the bones of the secondary palate.
Using a Peer-Mediated Instructional Package to Teach College Students With Intellectual and Developmental Disabilities to Navigate an Inclusive University Campus
Authors: Kearney Kelly B. , Joseph Brianna , Finnegan Lisa , Wood Jacqueline
Published: July 2020

Colleges across the nation have seen an increase in programming for students with intellectual and developmental disabilities (IDD) over the past decade. With this increase in programming comes the need to support students with IDD while accessing a large college campus. Using technology, such as Google Maps™, on one’s cell phone is a natural support that is relatively unobtrusive. This study used a peer-mediated instructional package consisting of total task presentation and error correction to teach college students with IDD how to use Google Maps™ to navigate a large, urban college campus in the southeastern United States. The results from this single-subject multiple probe design demonstrated that all students acquired the skills with 100% accuracy and maintained the skill once the instructional package was removed. Social validity data indicated that students thoroughly enjoyed learning the skill from the peer mediator. Implications and future research are discussed.
“Finding Rhythms Made Me Find My Rhythm in Prison”: The Role of a Music Program in Promoting Social Engagement and Psychological Well-being Among Inmates
Authors: Kyprianides Arabella , Easterbrook Matthew J.
Published: July 2020

This article presents a mixed-methods evaluation of the Finding Rhythms (FR) charity music program in U.K. prisons. Results across two studies indicate that FR group activities and the development of a shared FR identity lead to a positive well-being outcome. Furthermore, FR involvement dissolves rivalries between prisoners and provides them with a sense of purpose that extends into prison life and beyond. We provide evidence for the social cure properties of the FR group and the music program that promotes social engagement and psychological well-being among inmates.
A practical robust yaw servo architecture of ROVs by multi-vector propulsion and nonlinear controller
Authors: Song Dalei , Li Lin , Wang Changbin , Hou Renyu , Li Chong
Published: July 2020

Multi-vector arrangement is a novel propulsion architecture for remotely operated vehicles (ROV) because of its high manoeuvrability and efficiency, but the influence on the ROV dynamics and attitude servo control has not yet been clearly evaluated. This study fully investigated the kinematic behaviours of a hexagonal multi-vector propulsion ROV with communication delay constraint and reduced the complex model for precision control system design. An enhanced model-based PI robust controller (EMPRC) based on the nominal model is proposed to solve the nonlinear hydrodynamics and communication problems with high performance yaw control, whose stability is also analysed. The conventional proportional-integral-derivative (PID) and integral separation PID are used in the experiments for comparison. The results indicate that the proposed EMPRC can effectively track the desired attitude and reject the external disturbances, while the conventional ones are limited by the nonlinear dynamics and communication delays. The improvement is 3x on average in terms of overshoot, settling time and anti-disturbance recovery time compared to conventional algorithms and proves this proposed novel EMPRC is a practical solution for multi-vector propulsion ROVs.
Nonlinear distributed model predictive control with dual decomposition and event-based communication approach
Authors: Hammami Dine El Houda , Maraoui Saber , Bouzrara Kais
Published: July 2020

This paper proposes a dual decomposition method for solving distributed model predictive control. This controller is designed for systems subject to communication constraints, in which nonlinear subsystems interconnected via dynamics and by constraints. The interconnections are relaxed by using gradient method, accelerated gradient and alternating direction methods of multipliers. Also, an event-based communication is proposed to handle the issue of communication constraints especially in embedded systems. In the proposed event-based communication strategy, each controller solves the optimization problem and communicate only if the prices are updated significantly, which can reduce the computation load and release the burden of the network while achieving global performance. Finally, the simulations study of the four-tank benchmark is presented to demonstrate the effectiveness of the proposed schemes.
A hybrid fuzzy with feedback integral phase locked loop-based control strategy for unified power quality conditioner
Authors: Patjoshi Rajesh Kumar , Panigrahi Rakhee , Rout Shasanka Sekhar
Published: July 2020

This paper proposes a hybrid fuzzy control strategy comprising both Takagi-Sugeno fuzzy and Mamdani fuzzy along with novel feedback integral phase-locked loop based modified synchronous reference frame for unified power quality conditioner for power quality enhancement in power distribution network. The hybrid fuzzy controller can vary the gain nonlinearly for controlling dc-bus capacitor voltage of unified power quality conditioner, which limits the dc-bus voltage deviations during the load and supply voltage turbulences. Moreover, the proposed novel feedback integral phase-locked loop system is employed to improve the grid synchronization performance of unified power quality conditioner by considering the feedback integral loop and nonlinear adaptive-filter type phase detector approach. As a consequence, the proposed feedback integral phase-locked loop system can extract the positive sequence signal perfectly during power system disturbances. Additionally, the novelty of modified synchronous reference frame control technique relies upon nonintervention with low pass filter as well as high pass filter. Hence, the proposed control technique quickly and accurately extracts the reference signal from the distorted power system. The efficacy of the proposed control technique is justified through a real-time Opal-RT Hardware underneath different states of power system and compared with both conventional modified phase locked loop system and Takagi-Sugeno fuzzy with synchronous reference frame-based control system.
Computed Tomography Image Analysis and Clinical Correlations of Retromaxillary Cells
Authors: Cao Cheng , Zhou Fangwei , Song ZhiYan , Tao Zezhang , Xu Yu
Published: July 2020

Objective:

This study aimed to investigate and analyze the anatomic characteristics of the retromaxillary cell (RMC) by using computed tomography (CT) images of paranasal sinuses and to improve its identification with ethmomaxillary sinus (EMS).

Methods:

The paranasal sinus CT scans of 441 outpatients or inpatients in our hospital from January 2018 to October 2018 were analyzed. The incidence of RMC, EMS, Haller cell, imaging anatomical characteristics, and morphological manifestations were observed via sinus CTs. The relationship of RMC and ipsilateral maxillary sinusitis was analyzed.

Results:

The incidence of RMC is 83.90% (740/882). The incidence of males and females was 83.81% (414/494) and 84.02% (326/388), respectively. The incidence of bilateral (72.79%, 321/441) was much higher than that of unilateral (22.22%, 98/441). The lateral extension of the RMC ranged from 1.18 to 13.31 mm, with an average of 6.10 ± 2.03 mm. The incidence of ipsilateral maxillary sinus opacification on the RMC sides and non-RMC sides has no significance difference (χ2 = .054, P = .459). The incidence of Haller cell and EMS decreased significantly in the presence of RMC ( P < .01).

Conclusion:

The RMC is an anatomical variation originating from posterior ethmoid cells, which is commonly encountered in the clinic. The pneumatization of RMC is highly variable, and a bilateral is common. During endoscopic sinus surgery, it is necessary to carefully identify such an air cell to ensure the complete opening of the paranasal sinus during surgery.

Published: July 2020

To draw valid and reliable conclusions from child studies involving facial expressions, well-controlled and validated (child) facial stimuli are necessary. The current study is the first to validate the facial emotional expressions of child models in school-aged children. In this study, we validated the Radboud Faces Database child models in a large sample of children ( N = 547; 256 boys) aged between 8 and 12. In addition, associated validation measures such as valence, clarity, and model attractiveness were examined. Overall, the results indicated that children were able to accurately identify the emotional expressions on the child faces in approximately 70% of the cases. The highest accuracy rates were found for “happiness,” whereas “contempt” received the lowest accuracy scores. Children confused the emotions “fear” and “surprise,” and the emotions “contempt” and “neutral” with one another. Ratings of all facial stimuli are available (https://osf.io/7srgw/) and can be used to select appropriate stimuli to investigate the processing of children’s facial emotional expressions.
A Dyadic Analysis of Emotion Regulation as a Moderator of Associations Between Marital Conflict and Marital Satisfaction Among First-married and Remarried Couples
Authors: Frye Nick , Ganong Lawrence , Jensen Todd , Coleman Marilyn
Published: July 2020

We examined emotion regulation strategies as moderators of marital conflict and marital satisfaction between first-married and remarried couples. Remarried couples with a stepchild ( n = 108) and first marriage couples ( n = 111) with a child completed online surveys. Perceptions of both spouses were analyzed using actor–partner interdependence modeling. Although remarried spouses reported more marital conflict and lower marital satisfaction than first marriage spouses, emotion regulation strategies did not moderate the association between marital conflict and marital satisfaction differently for first-married and remarried couples. Expressive suppression exacerbated the negative association between marital conflict and marital satisfaction for men, and cognitive reappraisal attenuated the negative association for women. There was one partner effect; husbands’ greater cognitive reappraisal buffered the negative association between husbands’ marital conflict and wives’ marital satisfaction. Marriage order was less important than gender in how emotion regulation moderated the associations among marital conflict and marital satisfaction.
Oxygenator impact on voriconazole in extracorporeal membrane oxygenation circuits

Published: July 2020

Introduction:

To determine the oxygenator impact on alterations of voriconazole in a contemporary neonatal/pediatric (1/4 inch) and adolescent/adult (3/8 inch) extracorporeal membrane oxygenation circuit including the Quadrox-i® oxygenator.

Methods:

Simulated closed-loop extracorporeal membrane oxygenation circuits (1/4 and 3/8 inch) were prepared with a Quadrox-i pediatric and Quadrox-i adult oxygenator and blood primed. In addition, 1/4- and 3/8-inch circuits were also prepared without an oxygenator in series. A one-time dose of voriconazole was administered into the circuits, and serial pre- and post-oxygenator concentrations were obtained at 5 minutes, 1, 2, 3, 4, 5, 6, and 24 hour time points. Voriconazole was also maintained in a glass vial and samples were taken from the vial at the same time periods for control purposes to assess for spontaneous drug degradation

Results:

For the 1/4-inch circuit, there was an approximate mean of 64-67% voriconazole loss with the oxygenator in series and mean of 15-20% voriconazole loss without an oxygenator in series at 24 hours. For the 3/8-inch circuit, there was an approximate mean of 44-51% voriconazole loss with the oxygenator in series and a mean of 8-12% voriconazole loss without an oxygenator in series at 24 hours. The reference voriconazole concentrations remained relatively constant during the entire study period demonstrating that the drug loss in each size of the extracorporeal membrane oxygenation circuit with or without an oxygenator was not a result of spontaneous drug degradation.

Conclusion:

This ex vivo investigation demonstrated substantial voriconazole loss within an extracorporeal membrane oxygenation circuit with an oxygenator in series with both sizes of the Quadrox-i oxygenator at 24 hours and no significant voriconazole loss in the absence of an oxygenator. Further evaluations with multiple dose in vitro and in vivo investigations are needed before specific voriconazole dosing recommendations can be made for clinical application with extracorporeal membrane oxygenation.

Background. Observational economic evaluations (i.e., economic evaluations in which treatment allocation is not randomized) are prone to confounding bias. Prior reviews published in 2013 have shown that adjusting for confounding is poorly done, if done at all. Although these reviews raised awareness on the issues, it is unclear if their results improved the methodological quality of future work. We therefore aimed to investigate whether and how confounding was accounted for in recently published observational economic evaluations in the field of cardiology. Methods. We performed a systematic review of PubMed, Embase, Cochrane Library, Web of Science, and PsycInfo databases using a set of Medical Subject Headings and keywords covering topics in “observational economic evaluations in health within humans” and “cardiovascular diseases.” Any study published in either English or French between January 1, 2013, and December 31, 2017, addressing our search criteria was eligible for inclusion in our review. Our protocol was registered with PROSPERO (CRD42018112391). Results. Forty-two (0.6%) out of 7523 unique citations met our inclusion criteria. Fewer than half of the selected studies adjusted for confounding ( n = 19 [45.2%]). Of those that adjusted for confounding, propensity score matching ( n = 8 [42.1%]) and other matching-based approaches were favored ( n = 8 [42.1%]). Our results also highlighted that most authors who adjusted for confounding rarely justified their methodological choices. Conclusion. Our results indicate that adjustment for confounding is often ignored when conducting an observational economic evaluation. Continued knowledge translation efforts aimed at improving researchers’ knowledge regarding confounding bias and methods aimed at addressing this issue are required and should be supported by journal editors.

Published: July 2020

Background:

Arthroscopic iliopsoas tendon release is a surgical treatment option for painful snapping hips, although it has been associated with controversy surrounding potential complications including decreased hip flexion strength, iatrogenic hip instability, and iliopsoas atrophy.

Purpose:

To systematically assess the efficacy and safety of arthroscopic iliopsoas tenotomy during hip arthroscopic surgery as an intervention for painful snapping hips.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

A total of 3 online databases (Embase, PubMed, and MEDLINE) were searched from database inception until September 2019 for studies investigating iliopsoas tenotomy during hip arthroscopic surgery. Studies were screened by 2 reviewers independently and in duplicate, and studies investigating arthroscopic iliopsoas tendon release were included. Demographic data as well as data on treatment success, functional outcome scores, and radiological outcomes were recorded. A risk of bias assessment was performed for all included studies.

Results:

Overall, 21 studies were identified with a total of 824 patients (875 hips). These patients were 82.5% female (680/824), with a mean age of 28.1 years (range, 12-62 years) and mean follow-up of 32.1 months (range, 3-73 months). Arthroscopic iliopsoas tenotomy was performed at the level of the labrum in 811 hips (92.7%) or the lesser trochanter in 64 hips (7.3%). The overall reported success rate of the procedure in resolving snapping hips was 93.0% (266/286), and all studies reported an improvement in functional outcome scores. Only 6 studies (93 hips) discussed postoperative hip flexion strength, with complete recovery of strength reported in 4 studies (47 hips) and mild decreases reported in the other 2 studies (46 hips). Iliopsoas atrophy was evaluated radiologically (3 studies; 66 hips) and was found postoperatively in 92.4% (61/66) of hips. No major complications were reported.

Conclusion:

Arthroscopic release of the iliopsoas tendon was effective in alleviating pain and persistent clicking associated with a snapping hip. Although patients demonstrated some early postoperative weakness and iliopsoas atrophy on radiological imaging, the results from studies to date showed satisfactory clinical function and return to sports/activities. High-quality comparative studies are needed to further assess arthroscopic iliopsoas tendon release to determine the optimal technique and location of tendon release.
Risk Factors for Grade 3 Pivot Shift in Knees With Acute Anterior Cruciate Ligament Injuries: A Comprehensive Evaluation of the Importance of Osseous and Soft Tissue Parameters From the SANTI Study Group

Published: July 2020

Background:

Preoperative grade 3 pivot shift has been reported to be associated with higher rates of anterior cruciate ligament (ACL) failure, persistent instability, and inferior patient-reported outcomes. The etiology of a high-grade pivot shift is multifactorial, and numerous factors have been suggested to be responsible. More attention has recently been focused on injury to the anterolateral structures (ALS) as a risk factor for a grade 3 pivot shift.

Purpose:

To determine risk factors for grade 3 pivot shift, including soft tissue and osseous parameters.

Study Design:

Cross-sectional study; Level of evidence, 3.

Methods:

A prospective evaluation was undertaken of 200 consecutive patients undergoing acute ACL reconstruction (within 10 days of injury). An open exploration of the lateral side of the injured knee was performed at the time of the index procedure. Details regarding patient and injury characteristics were recorded, as were details of soft tissue injuries, including meniscal tears, ALS lesions, medial collateral ligament tears, and chondral injuries. Osseous parameters (tibial slope and condylar ratios) were determined per established magnetic resonance imaging protocols. A multivariate logistic regression with penalized maximum likelihood was used to identify risk factors associated with International Knee Documentation Committee (IKDC) grade 3 pivot shift.

Results:

The mean ± SD age of the population was 28.3 ± 9.8 years; 67.5% of patients were male. Among patients, 35 (17.5%) had a high-grade pivot shift (IKDC grade 3), and 165 (82.5%) had a low-grade pivot shift (IKDC grades 1 and 2). Univariate and multivariate logistic regression analysis demonstrated that injury to the ALS was the only significant risk factor for grade 3 pivot shift (odds ratio, 13.49; 95% CI, 1.80-1725.53).

Conclusion:

This comprehensive evaluation of soft tissue and osseous factors has identified that injury to the ALS is the most important risk factor for grade 3 pivot shift in acute ACL-injured knees.
Populations Are Differentiated in Biological Rhythms without Explicit Elevational Clines in the Plant Mimulus laciniatus

Published: July 2020

Environmental variation along an elevational gradient can yield phenotypic differentiation resulting from varying selection pressures on plant traits related to seasonal responses. Thus, genetic clines can evolve in a suite of traits, including the circadian clock, that drives daily cycling in varied traits and that shares its genetic background with adaptation to seasonality. We used populations of annual Mimulus laciniatus from different elevations in the Sierra Nevada in California to explore among-population differentiation in the circadian clock, flowering responses to photoperiod, and phenological traits (days to cotyledon emergence, days to flowering, and days to seed ripening) in controlled common-garden conditions. Further, we examined correlations of these traits with environmental variables related to temperature and precipitation. We observed that the circadian period in leaf movement was differentiated among populations sampled within about 100 km, with population means varying by 1.6 h. Significant local genetic variation occurred within 2 populations in which circadian period among families varied by up to 1.8 h. Replicated treatments with variable ecologically relevant photoperiods revealed marked population differentiation in critical day length for flowering that ranged from 11.0 to 14.1 h, corresponding to the time period between late February and mid-May in the wild. Flowering time varied among populations in a 14-h photoperiod. Regardless of this substantial population-level diversity, obvious linear clinality in trait variability across elevations could not be determined based on our genotypic sample; it is possible that more complex spatial patterns of variation arise in complex terrains such as those in the Sierra Nevada. Moreover, we did not find statistically significant bivariate correlations between population means of different traits. Our research contributes to the understanding of genetic variation in the circadian clock and in seasonal responses in natural populations, highlighting the need for more comprehensive investigations on the association between the clock and other adaptive traits in plants.
Current Practice Diagnosing Brain Death Is Not Consistent With Legal Statutes Requiring the Absence of All Brain Function
Authors: Nair-Collins Michael , Miller Franklin G.
Published: July 2020

The legal standard for the determination of death by neurologic criteria in the United States is laid out in the Uniform Determination of Death Act (UDDA), which requires the irreversible cessation of all functions of the entire brain. Most other nations endorse a “whole-brain” standard as well. However, current practice in the determination of death by neurologic criteria is not consistent with this legal standard, because some patients who are diagnosed as brain-dead, in fact retain some brain function, or retain the capacity for the return of some brain function. In response, the American Academy of Neurology published updated guidelines, which assert that hypothalamic function is consistent with the neurological standard enshrined in the UDDA. Others have suggested that it is an open question whether the hypothalamus and pituitary are part of “the entire brain,” as delineated in the UDDA. While we agree that determination of death practices are worthy of continued dialogue and refinement in practice that dialogue must adhere to reasonable standards of logic and scientific accuracy.
Enhanced tribological properties of bismaleimides with a novel hybrid silicon dioxide containing amino groups
Authors: Jia Yuan , Yang Juxiang , Hu Xue , Liu Zhen
Published: July 2020

To improve the tribological properties of bismaleimide (BMI) resin, silicon dioxide nanoparticles with imino and terminal functional amino groups were prepared through a sol–gel process to form a novel SiO2-NH2 hybrid. The as-prepared hybrid was then applied as a modifying agent for the BMI matrix to obtain SiO2-NH2/BMI composites. Compared to those of pure BMI resin, the volume wear rate and friction coefficient of the SiO2-NH2/BMI composites decreased significantly, while the wear mechanism changed from fatigue (BMI) to adhesive (SiO2-NH2/BMI) wear. This improvement in the tribological properties of the SiO2-NH2/BMI composites was attributed to the appropriate SiO2-NH2 added content, which endowed the BMI with excellent mechanical and thermal-resistant properties. Thus, the SiO2-NH2/BMI composites could resist the external load and excessive heat during the friction process.
