Abstract
Although many approaches have been proposed to manipulate propagating waves (PWs) and surface waves (SWs), usually each operation needs a separate meta-device, being unfavorable for optical integrations. Here, we propose a scheme to design a single meta-device that can efficiently generate SWs and/or PWs with pre-designed wavefronts, under the excitations of circularly polarized (CP) PWs with different helicity. As a proof of concept, we design and fabricate a microwave meta-device and experimentally demonstrate that it can convert incident CP waves of opposite helicity to SWs possessing different wavefronts and traveling to opposite directions, both exhibiting very high efficiencies. We further generalize our scheme to design a meta-device and numerically demonstrate that it can either excite a SW beam with tailored wavefront or generate a far-field PW with pre-designed wavefront, as shined by CP waves with different helicity. Our work opens the door to achieving simultaneous controls on far- and near-field electromagnetic environments based on a single ultra-compact platform.

Abstract
Although the first lasers invented operated in the visible, the first on-chip devices were optimized for near-infrared (IR) performance driven by demand in telecommunications. However, as the applications of integrated photonics has broadened, the wavelength demand has as well, and we are now returning to the visible (Vis) and pushing into the ultraviolet (UV). This shift has required innovations in device design and in materials as well as leveraging nonlinear behavior to reach these wavelengths. This review discusses the key nonlinear phenomena that can be used as well as presents several emerging material systems and devices that have reached the UV–Vis wavelength range.
Ultra-thin curved visible microdisk lasers with three-dimensional whispering gallery modes
Authors: Zhou Taojie , Ng Kar Wei , Sun Xiankai , Zhang Zhaoyu 
Published: July 2020

Abstract
Microdisk lasers are important components in photonic integrated circuits (PICs), of which the whispering gallery modes (WGMs) are usually confined within a two-dimensional (2D) planar slab. Here, owing to the strain relaxation of quantum wells by wet-etching method, we present ultra-thin curved visible microdisk lasers with single-mode lasing emission and a high quality factor of ∼17,000, which enable a 3D spatial intensity distribution of WGMs and provide an extra degree of freedom for the confined photons compared with the conventional 2D in-plane WGMs. The curved microdisk lasers with a 3D spatial profile of WGMs may provide attractive applications in flexible and multilevel photon sources for the PICs.
Undrained Responses of Partially Saturated Sand Induced by Biogas under Dynamic Cyclic Loading

Published: July 2020

Abstract
Desaturation denotes a methodology used to mitigate sand liquefaction. Signifying a new form of material, biogas is deemed more feasible for the purpose of desaturation. The present study entailed the adoption of a microbial denitrification process for generating nitrogen gas to induce specimens that are partially saturated. These specimens were utilized for the consolidated undrained triaxial tests performed isotropically. Based on a simplified process concerning the evaluation of liquefaction, the study provided the crucial degree of saturation for determining its minimum degree for averting liquefaction under varying intensities of earthquake. According to test findings, the soils’ liquification resistance grows with an increase in the saturation degree. The number of loading cycles used for initializing liquefaction increases to 34 cycles from 18 cycles under undrained asymmetricity as the extent of saturation reduces to 95.9 % from 100 % when the similarity of stress ratio is observed. Furthermore, the ratio of liquification resistance goes up in a linear pattern initially as the degree of saturation decreases. Meanwhile the ratio declines as the relationship becomes increasingly nonlinear. As a result, there is a gradual reduction in liquefaction resistance as the magnitude of earthquake rises, with a decline in the critical saturation degree. Notably, the extent of this decline is predicated on the relative density.

Pescadores e comerciantes de peixes na região da baixada cuiabanadesenvolvem diversas estratégias para dificultar a produção de provas de pesca predatória no Estado de Mato Grosso, em especial para o pescado das espécies: Cachara (Pseudoplatystoma fasciatum)e Pintado (Pseudoplatystoma corruscans).Estas duas espécies, agrupam qualidades inéditas do ponto de vista gastronômica epor essa razão, possuem grande lucratividade. Como a lei Estadual 9096 de 16 de janeiro de 2009 proíbe a captura de pescado através de diversos tipos de petrechos, em especial os específicos do artigo 25, item “V” letra “f” que trata sobre os petrechos de malha (rede e tarrafão), os contraventores escolhem a extração das cabeças dos animais no intuito de polemizar o método da captura e ainda o tamanho do pescado. Este estabelece um modelo estatístico para estas espécies de forma a reconstituir o tamanho do pescado apreendido mesmo sem a cabeça, viabilizando a estimativa pericial.
Musicoterapia en Polimicrogiria. Una propuesta de intervención
Authors: Ortega Raquel 
Published: July 2020

Este trabajo propone un protocolo de intervención musicoterapéutica para pacientes con polimicrogiria, una enfermedad rara que cursa con un incorrecto patrón de pliegues en la corteza cerebral. Tras realizar una revisión sobre esta patología, se han analizado las necesidades del colectivo abordables desde la musicoterapia estableciéndose unos objetivos terapéuticos. Según estos, se han diseñado las actividades. El protocolo diseñado, se ha testado en una paciente con polimicrogiria (13 meses de edad). Los resultados han sido favorables, ya que las sesiones han potenciado su atención mantenida, disminuido su frecuencia cardiaca, y estimulado su motricidad. También se valoraron los conocimientos previos sobre musicoterapia de los padres a través de un cuestionario, concluyéndose que esta terapia no está considerada oficialmente dentro de las terapias complementarias en polimicrogiria, pero ante los esperanzadores resultados obtenidos, se hace necesario realizar estudios con muestras mayores para poder obtener resultados representativos y establecer un protocolo sólido y validado.
Colour Preference for Two-Colour Combinations

Published: July 2020

What determines which colour combinations will be attractive to a person and which will not? Is colour attractiveness only a subjective human experience, or can we predict it based on physical colour parameters? One of the pioneers of the attraction of colour theories was Michel Eugène Chevreul (1786–1889). He distinguished two types of colour harmony – analog colour and contrast – and tried to describe what harmonics are based on physical colour parameters. This was later done by other scientists. Later, semantic evaluation of colours was introduced and factor analysis attempted to identify emotions caused by colours or combinations of colours. The aim of this research is to test whether there is a consistent pattern of judgments of colour combinations under controlled conditions and, if so, to what extent they are influenced by the objective physical characteristics of those combinations. Subjects. The study involved 40 students (20 men, 20 women). All subjects had normal colour vision and were not related to fine art. Research tools. The study used 8 colours: 4 opponent (green, red, yellow and blue) and 4 additional (orange, lettuce, blue and purple). The 28 colour combinations (made up of two different colours) were composed of those 8 colours and printed onto cardboard card where each colour had area of 80 mm x 80 mm. Questionnaire of 40 adjectives consisting of 20 pairs of antonyms were used for semantic colour assessment. Procedure. The investigation was conducted in a dark room. Initially, all 28 cards with colour combinations were placed randomly on a desk lit by a 40 cm high fluorescent lamp (4000K correlated colour temperature). The subject was asked to select one of the cards with the most preferable colour combination, to write its code on the questionnaire and to mark all the epithets in the questionnaire which suits this colour combination. The same procedure was applied to the all other cards. One experiment lasted 35–50 minutes. Results and conclusions. Independent component analysis distinguished 4 dimensions describing colours: pleasure, energy, purple color and strength. Logistic regression analysis was run on colour factor loadings to discriminate colour combinations into two groups: liked and disliked colour combinations. It shows that that colour combination could be predicted as being liked or disliked with 85% probability. Adding physical colour parameters to the regression increases prognostic probability to 92 %. Also a relationship between subjective factors and physical characteristics of colour combinations was found. Pleasure correlates with hue contrast and strength with saturation contrast. It can be argued that the reliability of colour combinations is determined by both subjective and physical factors.

Published: July 2020

OBJECTIVE:
The Centers for Disease Control and Prevention recommend testing for Chlamydia trachomatis in sexually active female patients &lt;25 years old using nucleic-acid amplification tests (NAAT) from a vaginal swab. Our providers were typically testing using the less sensitive urine NAATs. We aimed to increase the percentage of urogenital C trachomatis NAATs performed by using vaginal swabs in adolescent female patients ages 10 through 20 years from 1.4% to 25%.

METHODS:
We implemented 3 interventions at 3 pediatric practices over 12 months including education, process standardization, and cross-training. We used statistical process control to analyze the effect of interventions on our primary outcome: the percentage of urogenital C trachomatis tests performed with a vaginal swab. Our balance measure was the total number of urogenital C trachomatis tests.

RESULTS:
There were 818 urogenital C trachomatis tests performed: 289 before and 529 after the first intervention. Of urogenital C trachomatis tests in the preintervention time period, 1.4% were performed by using vaginal swabs. We surpassed our aim of 25% 6 weeks after the first intervention. We noted sustained improvement after the second intervention, with an average of 68.3% of tests performed by using vaginal swabs for the remaining postintervention period. There was no difference in the overall number of urogenital C trachomatis tests pre- and postintervention.

CONCLUSIONS:
Using quality improvement methodology and implementing easily replicable interventions, we significantly and sustainably increased use of vaginal swabs. The interventions standardizing processes were associated with a higher impact than the educational intervention.
A new set of tools for Ethnobiologist in the COVID-19 Pandemic
Authors: Ladio Ana H. 
Published: July 2020

This article will develop a series of ideas for ethnobiologists to consider in their professional field from now on. One of the things we have most learned about indigenous communities is the importance of being committed to maintaining the networks of life and the protection of diversity. Considering the warnings given by indigenous groups regarding past and future imbalances of Nature, what will happen to ethnobiological work in the future, and is what we do really necessary? What lines of action, conflict, alliances and controversies lie ahead of us. The so-called new normality urges us to make changes in our discipline, and therefore we should be able to count on a new box of tools. In a metaphorical sense, I will call these tools a set of premises that should never be lacking in the future; we must be alert to the signs of change, the omens and the previous experiences of local communities. These pandemic times have prioritized the voices of “experts”, who impose hegemonic scientific systems as if they were the only option. Indigenous peoples are neither heard nor valued, even though they are some of the worst affected by this pandemic, being subject to large-scale ethnocide at this moment. Our challenge as ethnobiologists should be to build bridges and be agents of change, so that multiculturality and interculturality can be made visible and promoted.

Práticas da Contabilidade Gerencial, Qualidade e Desempenho no Contexto de um Monopólio Natural
Authors: Correia Eliane Evangelista , Lima Afonso , Ching Hong Yuh 
Published: July 2020

Objetivo: Este artigo tem como objetivo analisar a relação entre o uso de artefatos da contabilidade gerencial e porte, desempenho e qualidade dos serviços prestados por empresas brasileiras concessionárias de distribuição de energia elétrica, setor configurado como monopólio natural, marcado por um grande número de regulações e restrito a um número limitado de estratégias orientadas ao desempenho.
Método: A pesquisa envolveu 22 concessionárias de um universo de 63; utilizou-se para a análise das relações os testes não-paramétricos Qui-quadrado, Kruskal-Wallis, U de Mann-Whitney e τ de Kendall.
Resultados: Resultados evidenciam maior frequência da utilização dos artefatos tradicionais e sugerem uma relação entre a utilização dos artefatos e o porte da empresa. Porém, não se verificou uma relação entre a utilização desses artefatos e o desempenho nas organizações investigadas (diferenciando-se de outras pesquisas), nem com a qualidade dos serviços. Pode-se concluir que, nesse contexto de monopólio natural, informações obtidas por meio de artefatos não se prestam ao aperfeiçoamento das operações, apesar das iniciativas de um pequeno número de organizações.
Contribuições: Diversos estudos têm investigado a relação entre práticas da contabilidade gerencial (artefatos) e o desempenho organizacional em diferentes contextos, porém, pouco se sabe acerca dessa relação no contexto de setores altamente regulados.

Published: July 2020

Objetivo: Compreender os elementos cognitivos e comportamentais no ambiente socioacadêmico mostra-se como uma agenda emergente de pesquisa na área de educação contábil. A partir desse incentivo, o artigo busca identificar a associação entre as estratégias de coping adotadas por discentes brasileiros de contabilidade.

Método: A amostra representa 311 discentes de contabilidade de Instituições de Ensino Superior localizadas no Sul do Brasil. Os dados, coletados por meio uma survey foram tratados a partir de correlação de Spearman.

Resultados: As estratégias de coping, representadas por ações comportamentais em resposta a situações de estresse, exaustão emocional e pressão, adotadas por discentes de contabilidade do Brasil mostram-se associadas e conduzem o comportamento desejáveis e indesejáveis do mesmo no ambiente socioacadêmico.

Contribuição: A universidade precisa integrar os processos relacionados as estratégias de coping no ambiente socioacadêmico por meio de políticas de atenção e apoio aos discentes, visto estar atrelado ao desenvolvimento acadêmico e as experiências que o discente desencadeará durante a sua permanência no ensino superior. Contribui-se com a promoção da temática junto as instituições de ensino, pois o ensino superior apresenta-se como uma verdadeira arena do jogo, na qual todos os atores possuem responsabilidades.
A Relação entre a estrutura de propriedade e o custo da dívida captada via emissão de debêntures no Brasil

Published: July 2020

Objetivo: Esta pesquisa teve como objetivo identificar a relação entre a estrutura de propriedade/controle das empresas e o custo da captação de dívida via emissão de debêntures.
Método: Foram examinadas as características de concentração de controle, concentração de propriedade e diferença entre controle e propriedade, em relação à taxa de juros (spread) paga pelas companhias de capital aberto na emissão de debêntures entre 2011 e 2018. Os dados foram analisados por meio de regressões lineares e quadráticas.
Resultados: Os resultados encontrados sugerem que, dentre as características de estrutura de propriedade/controle analisadas, somente a concentração de controle é relevante para os debenturistas no momento da precificação dos títulos.
Contribuições: A pesquisa contribui à literatura ao evidenciar que a relação entre concentração de controle e spread é quadrática. Assim, até certo ponto, o aumento da concentração de controle se reflete no aumento do custo da dívida; porém, quando essa concentração se torna muito elevada, os credores a interpretam como algo benéfico, reduzindo o custo da dívida. Tais resultados sugerem tanto os efeitos positivos e negativos decorrentes da concentração de controle estão presentes na captação de dívida; porém, os benefícios tendem a se manifestar apenas quando a concentração de controle se torna elevada.
Dynamic Tilt Correction Using Direct Rotational Motion Measurements
Authors: Bernauer Felix , Wassermann Joachim , Igel Heiner 
Published: July 2020

AbstractInertial sensors like seismometers or accelerometers are sensitive to tilt motions. In general, from pure acceleration measurements, it is not possible to separate the tilt acceleration from the translational ground acceleration. This can lead to severe misinterpretation of seismograms. Here, we present three different methods that can help solving this problem by correcting translational records for dynamic tilt induced by ground deformation with direct measurements of rotational motions: (1) a simple time-domain method, (2) a frequency-domain method proposed by Crawford and Webb (2000) using a coherence-weighted transfer function between rotation and acceleration, and (3) an adapted frequency-domain method that corrects only those parts of the spectrum with coherence between translational acceleration and rotation angle higher than 0.5. These three methods are discussed in three different experimental settings: (1) a reproducible and precisely known laboratory test using a high-precision tilt table, (2) a synthetic test with a simulated volcanic very-long-period event, and (3) a real data set recorded during the 2018 Mt. Kīlauea caldera collapse. All the three test cases show severe influence of tilt motion on the acceleration measurements. The time-domain method and the adapted frequency-domain method show very similar performance in all three test cases. Those two methods are able to remove the tilt component reliably from the acceleration record.
Salud mental en la actualidad
Authors: Calvo Soto Andrea 
Published: July 2020

Los trastornos mentales como la depresión, el trastorno de angustia, la ansiedad generalizada, el trastorno obsesivo compulsivo, entre otros, han existido siempre, pero las condiciones de nuestra sociedad relacionados con el mercado, la producción, el conocimiento, etc., implican para las personas unos importantes niveles de exigencia, así como otras formas de relacionarse, con los demás, con la tecnología, volviendo el entorno altamente competitivo, todas esas presiones pueden llevar al límite la salud mental. Esto se evidencia en el creciente número de personas con problemas de salud mental que reportan los entes sanitarios, incluyendo el suicidio dentro de las cifras de mortalidad. Las consecuencias de los problemas mentales también pueden llevar a repercusiones físicas como: dolores musculoesqueléticos, trastornos gástricos, debilitamiento del sistema inmunitario, enfermedad cardíaca y otras afecciones.
The Principle of Salus Animarum as the Essence of the Adversarial System Under Canon Law
Authors: Greszata-Telusiewicz Marta 
Published: July 2020

Zasada salus animarum jako istota kontradyktoryjności w systemie prawa kanonicznego
Zasada kontradyktoryjności jest warunkiem zaistnienia iudicium. Do powstania każdego proce- su, w tym również kanonicznego procesu o nieważność małżeństwa, potrzebne jest bowiem czyjeś twierdzenie wyrażające wolę realizacji swojego uprawnienia z jednoczesnym zaistnieniem twierdzenia przeciwnego, które również w swej treści wyraża wolę realizacji tego samego uprawnienia. W tym czasie, gdy te dwa sprzeczne ze sobą twierdzenia zaistnieją jednocześnie przed sędzią kościelnym, powstaje spór, który następnie może przekształcić się w iudicium.
Taką wolę rozumienia procesu kanonicznego jako kontradyktoryjnego, wyraża również Papież Franciszek w MIDI, przypominając dotychczasowe unormowania i reformując jedynie te procedury, które tego wymagały zgodnie z duchem czasu. Wprowadzenie tych zmian ma na celu pozbycie się z treści iudicium jedynie tego, co się zdewaluowało, przy czym trzon kontradyktoryjności pozostaje niewzruszony. Papież Franciszek pisze w MIDI: „…troska o zbawienie dusz, która – zarówno dzisiaj, tak jak w przeszłości – pozostaje najwyższym celem instytucji, ustaw i prawa, skłania Biskupa Rzymu do przedstawienia biskupom niniejszego aktu reformy”. Takie właśnie uzasadnienie staje u podstaw reformy Franciszkowej procesu kanonicznego opartego na zasadach procesowych.
