APONTAMENTOS DA LÍNGUA OFAIÉ (MACRO-JÊ) DIANTE DO CONTATO LINGUÍSTICO
Authors: Ferreira Rogério Vicente , Gomes Nataniel dos Santos
Published: May 2021

Este artigo apresenta uma reflexão sobre as palavras neológicas na língua Ofaié, oriundas do contato linguístico. A língua Ofaié está em perigo de extinção, sendo classificada como pertencente ao Tronco Macro-Jê. Entre os fatores que colaboraram para que a língua chegasse a este estágio, temos a assimetria predominante em relação ao português, o que, certamente, contribuiu como um aspecto de maior impacto. O povo ofaié se encontra entre a minoria que possui sua língua nativa ameaçada. Diante disso, olhar para as criações lexicais como parte do contato com a língua majoritária, ou seja, a língua portuguesa, também é uma forma de preservar a memória lexical desse povo. Este trabalho segue bases epistemológicas de Couto (2009), Trasck (2004), Weinreich (1970), Correira (2012), Langacker (1972), entre outros. Esta reflexão é parte da pesquisa desenvolvida sobre o léxico da língua ofaié.

Objetivo: descrever as vivências de estudantes do curso de graduação em enfermagem ao integrar o projeto de extensão Desafios da acessibilidade no campus universitário da UFSC: transformando a realidade e o processo de formulação e implementação dessa atividade. Método: relato de experiência fundamentado nas vivências experimentadas pelos acadêmicos. Resultados: Os dados revelaram que o conceito de deficiência para os acadêmicos era imerso em estigmas sociais e culturais distantes da concepção de diversidade humana, assim como ficou evidente que apenas considerava-se acessibilidade medidas físicas de adaptação, suprimindo qualquer outra medida social ou comportamental. Conclusão: Tendo em vista que a deficiência é um fenômeno complexo que exige intervenções coletivas para eliminar barreiras do ambiente e da sociedade, acredita-se que é essencial estimular discussões a este respeito.

BOTÂNICA SISTEMÁTICA E O ENSINO REMOTO: POSSIBILIDADES TECNOLÓGICAS E LIMITAÇÕES NEUROEDUCACIONAIS
Authors: Cunha Lucas Gonçalves
Published: May 2021

Introdução: O ensino da botânica divide opiniões, do amor à aversão, o sentimento é fruto da complexidade atribuída às bases necessárias para o aproveitamento da disciplina. O ano de 2020 chegou, e com ele a necessidade da adoção, em instituições de ensino superior como a Universidade Federal de Santa Maria, do Regime de Exercícios Domiciliares Especiais, devido ao isolamento social imposto pela pandemia. Objetivo: Assim, esta pesquisa objetiva abordar as possibilidades tecnológicas e limitações relacionadas a neuroeducação no exercício da disciplina de botânica sistemática em uma turma de engenharia florestal. Material e métodos: O acompanhamento da disciplina se deu no segundo semestre letivo do ano de 2020, que ocorreu de 26/10/2020 à 02/02/2021. Foram observados os benefícios relatados por professores e alunos, e também as insatisfações por parte de ambos, assim como realizada uma análise das implicações neurobiológicas e cognitivas sobre a aprendizagem do presencial x remoto. Resultados: Relacionado à questão tecnológica, os benefícios se deram em duas esferas, primeiramente quanto a visualização plena de estruturas muito pequenas, que não poderiam ser vistas de maneira tão clara em aulas de campo, seguido pela visualização das estruturas por todos os alunos, fato que é complexo em aulas presenciais de campo, pois o professor necessitaria explicar inúmeras vezes, visto que uma única turma pode ter até 50 graduandos. Quando abordamos a neuroeducação e aquilo que configura a aprendizagem, é nítido que, apesar da visualização clara das estruturas, a perspectiva multissensorial não é exercida, não sendo explorado aquilo que autores da grande área da neurobiologia consideram como ideal para o aprendizado. Conclusão: O ensino da botânica de maneira remota deve oferecer aos educandos aulas elaboradas com auxilio de lupas e imagens microscópicas, mas deve priorizar que os alunos realizem coletas de material vegetal para análises em partes de plantas reais.

Introdução: O impacto ambiental do lixo plástico nos oceanos revelam que, a cada seis anos cerca de 5,25 trilhões de partículas de plástico são jogados nos mesmos, isso equivale a 269 mil toneladas de plásticos descartados inadequadamente. Parte desse plástico no formato de microplástico e nano plástico entra na cadeia alimentar, prejudicando diversos organismos, inclusive humanos. Objetivos: Seu principal objetivo foi estimular os estudantes a trazerem para a escola garrafas, squeeze ou copos reutilizáveis, como medida para reduzir o uso de copos descartáveis. Material e métodos: A pesquisa foi realizada na EREM Herculano Bandeira, localizada no município de Paudalho / PE, há 40 km de Recife. Com a publicação do Decreto Estadual nº 48.810 de 16/03/2020 que suspendeu as aulas em todo o território pernambucano por conta da pandemia, algumas etapas do projeto foram executadas através de aplicativos de mensagens ou redes sociais. Foram utilizados estes aplicativos para disponibilizar o questionário diagnóstico para avaliar a consciência dos alunos quanto ao lixo plástico produzido diariamente e da importância em contribuir na redução. Com a COVID-19, o trabalho de sensibilização se estendeu também, quanto à necessidade do uso individual de copos ou garrafas. Como estratégia para pertencimento das etapas de implantação, foi realizada, por meio de votação através de aplicativo de mensagem, entre alunos, professores e equipe gestora, a escolha da logomarca do projeto “Adote um copo”. Resultados: Embora 75% dos alunos responderem que trazem copo ou garrafa para a escola, paradoxalmente, este mesmo percentual, gostaria que a escola disponibilizasse copos descartáveis. Além de 54% acreditarem que os copos descartáveis são reciclados em nosso município. Importante registrar que desde 2019 tem fornecido copos reutilizáveis aos alunos para o consumo se suco durante as refeições, num entanto, talvez a falta de campanhas de sensibilização faça com que em pouco tempo os copos sejam deixados em casa. Conclusão: Existe a necessidade de reedições constantes de oficinas para sensibilização e conscientização dos alunos, sobre a importância de reduzir/eliminar o uso de copos descartáveis, tendo em vista estarem vivenciando uma fase dinâmica de construção do conhecimento.
Big Data Analytics in Health Care: A Review Paper
Authors: Mohammad Yousef Maria
Published: May 2021

The application of big data in health care is a fast-growing field, with many discoveries and methodologies published in the last five years. Big data refers to datasets that are not only big but also high in variety and velocity, which makes them difficult to handle using traditional tools and techniques. Moreover, medical data is one of the most growing data, as it is obtained from Electronic Health Records (EHRs) or patients themselves. Due to the rapid growth of such medical data, we need to provide suitable tools and techniques in order to handle and extract value and knowledge from these datasets to improve the quality of patient care and reduces healthcare costs. Furthermore, such value can be provided using big data analytics, which is the application of advanced analytics techniques on big data. This paper presents an overview of big data content, sources, technologies, tools, and challenges in health care. It also intends to identify the strategies to overcome the challenges.

Authors: Mamman Maharazu , Mohd Hanapi Zurina
Published: May 2021

Recently, many generations of mobile networks have changed from one transition to another transition. The mode of transition from the first generation (1G) to the fifth generation (5G) is characterized by a lot of performance challenges such as delay, speed of the users, mobility, and variety of services. Currently, different from prior generations, 5G is not only concerned with the mobile networks but also, with various applications and different services such as health sector, transportation, energy consumption, safety well as Smart City. All these services are incorporated by 5G. In this paper, we proposed a call admission control (CAC) algorithm with an efficient handoff for both 4G and 5G networks. Simulation is used to evaluate the effectiveness of the proposed algorithm, and the obtained results indicate it considerably performs better than do other algorithms based on valuable metrics such as data throughput, call blocking probability (CBP), and call dropping probability (CDP).

A study of factors shaping learners' perceptions of ICT-based teaching and learning by applying personality and technology adoption theories on indigenous knowledge students
Authors:   , Ngcobo Khumbuzile Mornica
Published: May 2021

Existing literature indicates that the use of Information and Communication Technologies (ICTs) and the inclusion of Indigenous Knowledge Systems (IKSs) in the school curriculum have the potential to increase academic performance. However, formal education is still unable to integrate ICTs into the teaching and learning of school subjects, especially, those that are related to IKSs. This research therefore aims to construct a model of the factors shaping learners’ perceptions on the usefulness of ICTs for the teaching and learning of IKSs. This aim is sub-divided into four research objectives: (a) to identify appropriate technology diffusion theories for the investigation of the factors shaping learners’ perceptions on the usefulness of ICTs for the teaching and learning of IKSs, (b) to construct a theoretical model of the factors shaping learners’ perceptions on the usefulness of ICTs for the teaching and learning of IKSs, (c) to perform an empirical confirmation of the above announced theoretical model of the factors shaping the perceptions of learners on the usefulness of ICTs for the teaching and learning of IKSs, and (d) to suggest new ideas for future research on learners’ perceptions on the usefulness of ICTs for the teaching and learning of IKSs. A review of existing literature on eLearning adoption by students and learners was conducted in order to achieve objectives a, b, and d. As for objective c, it was achieved through the survey of 115 Hospitality studies learners from the ILembe and UMgungundlovu municipality districts in the KwaZulu-Natal (KZN) province of South Africa. The study’s findings can be summarized as follows: (a) The Technology Adoption Model (TAM) is the backbone of the model designed by this study on the factors affecting learners’ perceptions of the usefulness of ICTs for the teaching and learning of IKSs; (b) Learners’ perceived usefulness of ICTs is hypothetically affected by the following factors: demographics, computer self-efficacy, trust in ICTs, and level of conscientiousness, (c) All these factors were empirically confirmed through a survey conducted by the current study, except that the only validated demographics were : school location, cell phone access, class grade and preferred subject; (d) This research recommends further investigation on the factors affecting learners’ perceived usefulness of ICTs for the teaching and learning of IKSs, mainly because of the insufficient literature on this subject.

Authors: Saputra Boby
Published: May 2021

Organizational culture is viewed positively by members of the organization so it is expected that the attitudes and behaviors that arise will be positive. The achievement of organizational goals is strongly influenced by the organizational culture. If the organizational culture is conducive enough, members of the organization will have a commitment to the organization. The commitment of employees to the organization will be reflected in their satisfaction with work. One of the things that can motivate employees to work is to meet their expectations / needs in organization, if their needs are met, then they will try to keep working well in the organization. This is what then gives birth to employee commitment to the organization, so that they use all their abilities properly for the development of the progress of their organization and in the end the organizational goals will be realized. Based on the description above, there is an interest in conducting research with the title: "The influence of organizational culture on employee commitment at PT. Pemantang Abaditama”.

The purpose of this study are as follows: to determine the significant influence of organizational culture on employee commitment of PT. Pemantang Abaditama. The population in this study were employees at PT. Pemantang Abaditama. The statistical method used is linear regression analysis.

Based on the results of this study, the value of F count on the organizational culture variable was 4.182 with a significant level of 0.046. Because the significant level in this variable is less than 5% (sig <5%), then H0 is rejected and H1 is accepted. This means that the variable organizational culture has an effect on Organizational Commitment. The conclusion in this study is that organizational culture factors have a significant effect on organizational commitment, this is because employees of PT. Pemantang Abaditama can form a conducive culture in the form of creating a conducive work atmosphere and this will later be able to influence employee commitment so that it will improve employee performance.

Published: May 2021

Türklerin çok eskiden beri müzik terapi ile ilgilendikleri, şamanların tedavileri ile şifa buldukları dünya müzik tarihlerinde aktarılır. Dünya müzikologlarının ve psikologların ilgilendikleri ortak bir alan olan müzik terapinin Türk müziği tarihi açısından kaynaklardaki bilgilerin de henüz yeterince incelendikleri söylenemez. Türk müziği tarihini yakından ilgilendiren kaynakların yazıldığı anlardan biri de eski Yunan ve Orta Doğu müzik kültürünün kaynaştığı İslam medeniyeti dönemidir. Günümüze müzikle ilgili eseri gelmiş en eski İslam filozoflarından ve müzik tarihinin Yazım Dönemi müzik risaleleri sahiplerinden biri olan Yakup Kindi’nin müzik terapi konusunda ne düşündüğü bugüne kadar incelenmemiş olduğu dikkat çekmiştir. Bu makalenin amacı Kindi’nin müzik terapi konusundaki fikirlerini incelemek olacaktır. Makalenin incelemesi Kindi’nin müzik risalesi ile sınırlıdır. Kindi’nin, müziğin insan psikolojisinde uyandırdığı etkiyi sık sık dile getirdiği anlaşılmaktadır. O, müziğin hem nağme, hem ika, hem de güfte uyumuna dikkat çeker. Buna ilave olarak, müzik terapi etkisini artırmak için, Kindi’nin renk ve kokulardan yararlanılmasını istemesi ilginç sonuçlardandır.
HOW RELIGIOUS BELIEFS SHAPE CONSUMER BEHAVIOR: AN EXPLORATORY AND PURELY QUALITATIVE STUDY ON CHRISTIAN, MUSLIM, AND TRADITIONAL CONSUMERS IN BURKINA FASO
Authors: Nassè Dr. Théophile Bindeouè
Published: May 2021

There is no doubt that religion affects consumer behavior in the African context as well as in other geographies. While a lot of research has been done in other contexts, very little research has been conducted in the West African Geography. The purpose of this research is to explore the concepts of religious beliefs and consumer behavior in Burkina Faso to consider the role of culture in management and particularly in the marketing of products. Burkina Faso is a country where religion plays an important role. While the consumption of industrial non-alcoholic beverages is increasing, religious beliefs constitute a stumbling block that moderates the consumption of industrial non-alcoholic beverages. The approach is an exploratory qualitative one assorted with a sound documentary analysis. The qualitative data collection is performed with a digital voice recorder by the means of some semi-structured interviews. The number of semi-structured interviews recorded is 16. Then, the qualitative data is transcribed by hand. Results show that religious beliefs affect and moderate consumer behavior.

ORGANIC REVELATION IN THE THEOLOGY OF HERMAN BAVINCK
Authors: Phen Rudy
Published: May 2021

The reality of the Trinity compels Bavinck to view the revelation as one single historical and organic whole, a mighty world controlling and world-renewing system of testimonies and acts of God. Organism is the appropriate apparatus to describe the unity-in-diversity of the external (ad extra) work of the triune God and it serves as an agent of unity in Bavinck's theology. He has formulated a unified and organic Reformed doctrine of revelation that is founded on his Trinitarian vision and has presented it as the key concept of Christian worldview.KEYWORDS: Trinity; Herman Bavinck; revelation; organic; unity-indiversity; worldview; ad intra; ad extra.
TINJAUAN KONSEP IMAGO DEI IRENAEUS DAN THOMAS DARI PERSPEKTIF YOHANES CALVIN SERTA DAMPAKNYA BAGI ZAMAN PASCA MILLENIAL
Authors: Hutahaean Tumpal
Published: May 2021

This article seeks to express the uniqueness of John Calvin's understanding of the meaning of Imago Dei as his reaction to the understanding of the theologians of Irenaeus and Medieval Scholastic Aquinas, then to explain the implications of Imago Dei theologically in the context of God's creation along with its significance on self-identity in the digital age. Calvin restores Imago Dei's view back to the bible. His thesis is human must have the right knowledge about God and himself. It is only through Jesus Christ and His word can a man be renewed and knows himself as Imago Dei, so that he can glorify God again. And it is only through the work of the Holy Spirit can man reflects God in this world.

KEYWORDS: Imago Dei; total depravity; redemption; renewal; knowing oneself.
The Impact of Investment in Human Capital on the Exports of Goods and Services
Authors: Siddique Samina , Mahmood Zafar , Noureen Shabana
Published: May 2021

With the growth of services economy worldwide, it has become essential for policymakers to comprehend the export competitiveness of nations to identify offshore export locations or alternatively offer their own sites as an exporting location. Human capital investment is considered as a key component in attracting foreign countries for outsourcing purposes. Earlier studies have shown mixed role of human capital investment on off shoring activities. This study assesses the effects of control variables (business environment, wages and IT infrastructure) and human capital investment on export of goods and services from the selected Asian outsourcing countries. Panel Estimated Generalized Least Square (EGLS) technique is used with country weights to specifically overcome the problem of autocorrelation. Empirical findings show that investment in human capital is significant for both goods and services exports. We found a large impact of human capital investment on exports of goods and services in selected Asian countries as compared to selected developed countries. Empirical findings further suggest that human capital is more essential for export of goods than export of services. From these findings, the study draws important implications for policymaking in countries who intend to offer themselves as an attractive location for exporting and for those who intend to locate their production activities overseas.

Abstract. On-road vehicle emissions are a major contributor to significant atmospheric pollution in populous metropolitan areas. We developed an hourly-based, link-level emissions inventory of vehicular pollutants using two land-use machine learning methods based on the datasets of road traffic monitoring in the Beijing-Tianjin-Hebei (BTH) region. The results indicate that a land-use random forest (LURF) model is more capable of predicting traffic profiles than a Gaussian process regression (GPR) model. The inventories under three different traffic scenarios depict a significant temporal and spatial variability in vehicle emissions. One notable finding is that NOX, fine particulate matter (PM2.5) and black carbon (BC) emissions from heavy-duty trucks (HDTs) in general have higher emission intensity on the highways connecting to regional ports. Even when traffic restrictions were implemented, a detour of the HDTs in Hebei was observed resulting in relatively lower emission reductions in Hebei than Beijing. This study demonstrates the power of machine learning approaches to generate data-driven and high-resolution emission inventories, which provides a platform to realize the near real-time process of establishing high-resolution vehicle emission inventories for policy makers to engage in sophisticated traffic management.
Insights into wind turbine reflectivity and radar cross-section (RCS) and their variability using X-band weather radar observations

Published: May 2021

Abstract. The increasing need of renewable energy fosters the expansion of wind turbine sites for power production throughout Europe with manifold effects, both on the positive and negative side. The latter concerns, among others, radar observations in the proximity of wind turbine (WT) sites. With the aim of better understanding the effects of large, moving scatterers like wind turbines on radar returns, MeteoSwiss performed two dedicated measurement campaigns with a mobile X-band Doppler polarimetric weather radar (METEOR 50DX) in the northeastern part of Switzerland in March 2019 and March 2020. Based on the usage of an X-band radar system, the performed campaigns are up to now unique. The main goal was to quantify the effects of wind turbines on the observed radar moments, to retrieve the radar cross-section (RCS) of the turbines themselves and to investigate the conditions leading to the occurrence of the largest RCS. Dedicated scan strategies, consisting of PPI (plan position indicator), RHI (range–height indicator) and fixed-pointing modes, were defined and used for observing a wind park consisting of three large wind turbines. During both campaigns, measurements were taken in 24/7 operation. The highest measured maxima of horizontal reflectivity (ZH) and RCS reached 78.5 dBZ and 44.1 dBsm, respectively. A wind turbine orientation (yawing) stratified statistical analysis shows no clear correlation with the received maximum returns. However, the median values and 99th percentiles of ZH show different enhancements for specific relative orientations. Some of them remain still for Doppler-filtered data, supporting the importance of the moving parts of the wind turbine for the radar returns. Further, we show, based on investigating correlations and an OLS (ordinary least square) model analysis, that the fast-changing rotor blade angle (pitch) is a key parameter, which strongly contributes to the variability in the observed returns.
Uncertainty of hourly-average concentration values derived from non-continuous measurements
Authors: Haszpra László , Prácser Ernő
Published: May 2021

Abstract. Continental greenhouse gas monitoring networks extensively use tall towers for higher spatial representativeness. In most cases, several intakes are built along the tower to give information also on the vertical concentration profile of the components considered. Typically, a single gas analyzer is used, and the intake points are sequentially connected to the instrument. It involves that the continuous concentration signal is only sampled for discrete short periods at each intake point, which does not allow for a perfect reconstruction of the original concentration variation. It increases the uncertainty of the calculated hourly averages usually used by the atmospheric transport and budget models. The purpose of the study is to give the data users an impression of the potential magnitude of this kind of uncertainty, as well as how it depends on the number of intakes sampled, on the length of the sampling period at each intake, on the season, and on the time of the day. It presents how much improvement can be achieved using linear or spline interpolation between the measurement periods instead of the simple arithmetic averaging of the available measurements. Although the results presented here may be site-specific, the study calls attention to the potentially rather heterogeneous spatial and temporal distribution of the uncertainty of the hourly-average concentration values derived from tall-tower measurements applying sequential sampling.

Abstract. This study assesses marine biological production of organic carbon based on the diel variability of bio-optical properties monitored by two BioGeoChemical-Argo (BGC-Argo) floats. Experiments were conducted in two distinct Mediterranean systems, the Northwestern Ligurian Sea and the Central Ionian Sea during summer months. We derived particulate organic carbon (POC) stock and gross community production integrated within the surface, euphotic and subsurface chlorophyll maximum (SCM) layers, using an existing approach applied to diel cycle measurements of the particulate beam attenuation (cp) and backscattering (bbp) coefficients. The diel cycle of cp provided a robust proxy for quantifying biological production in both systems; that of bbp was comparatively less robust. Derived primary production estimates vary by a factor of 2 depending upon the choice of the bio-optical relationship that converts the measured optical coefficient to POC, which is thus a critical step to constrain. Our results indicate a substantial, yet variable, contribution to the water column production of the SCM layer (16–42%). In the Ligurian Sea, the SCM is a seasonal feature that behaves as a subsurface biomass maximum (SBM) with the ability to respond to episodic abiotic forcing by increasing production. In contrast, in the Ionian Sea, the SCM is permanent, induced by phytoplankton photoacclimation and contributes moderately to water column production. These results emphasize the strong potential for transmissometers deployed on BGC-Argo profiling floats to quantify non-intrusively in situ biological production of organic carbon in the water column of stratified oligotrophic systems with recurring or permanent SCMs, which are widespread features in the global ocean.
Ozone-induced gross primary productivity reductions over European forests inferred from satellite observations

Published: May 2021

Abstract. Tropospheric O3 damages leaves and directly inhibits photosynthesis, posing a threat to terrestrial carbon sinks. Previous investigations have mostly relied on sparse in-situ data or simulations using land surface models. This work is the first to use satellite data to quantify the effect of O3 exposure on gross primary productivity (GPP). O3-induced GPP reductions were estimated to vary between 0.36–9.55% across European forests along a North-South transect between 2003–2015, in line with prior estimates. No significant temporal trend could be determined over most of Europe, while Random Forest analysis (RFA) shows that soil moisture is a significant variable governing GPP reductions over the Mediterranean. Comparisons between this work and GPP reductions simulated by the Yale Interactive Biosphere (YIBs) model suggest that satellite-based estimates over the Mediterranean region may be biased by +12%, potentially because of differences in modelling stomatal sensitivity to soil moisture and prior O3 exposure. This work has demonstrated for the first time that satellite-based datasets can be leveraged to assess the impact of O3 on the terrestrial carbon sink, which are comparable with in-situ or model-based analyses.
Sensitivity of precipitation and temperature over the Mount Kenya area to physics parameterization options in a high-resolution model simulation performed with WRFV3.8.1
Authors: Messmer Martina , González-Rojí Santos J. , Raible Christoph C. , Stocker Thomas F.
Published: May 2021

Abstract. Several sensitivity experiments with the Weather Research and Forecasting (WRF) model version 3.8.1 have been performed to find the optimal parameterization setup for precipitation amounts and patterns around Mount Kenya at a convection-permitting scale of 1 km. Hereby, the focus is on the cumulus scheme, with tests of the Kain–Fritsch, the Grell–Freitas, and no cumulus parameterizations. In addition, two longwave radiation schemes and two planetary boundary layer parameterizations are evaluated, and different nesting ratios and numbers of nests are tested. The precipitation amounts and patterns are compared against a large amount of weather station data and three gridded observational data sets. The temporal correlation of monthly precipitation sums show that fewer nests lead to a more constrained simulation, and hence the correlation is higher. The pattern correlation with weather station data confirms this result, but when comparing it to the most recent gridded observational data set the difference between the number of nests and nesting ratios is marginal. The precipitation patterns further reveal that using the Grell–Freitas cumulus parameterization in the domains with resolutions >5 km provides the best results when it comes to precipitation patterns and amounts. If no cumulus parameterization is used in any of the domains, the temporal correlation between gridded and in situ observations and simulated precipitation is especially poor with more nests. Moreover, even if the patterns are captured reasonably well, a clear overestimation in the precipitation amounts is simulated around Mount Kenya when using no cumulus scheme in all domains. The experiment with the Grell–Freitas cumulus parameterization in the domains with resolutions >5 km also provides reasonable results for 2 m temperature with respect to gridded observational and weather station data.

Abstract. A high-resolution (1/20∘) global ocean general circulation model
with graphics processing unit (GPU) code implementations is developed based on
the LASG/IAP Climate System Ocean Model version 3 (LICOM3) under a
heterogeneous-compute interface for portability (HIP) framework. The dynamic
core and physics package of LICOM3 are both ported to the GPU, and
three-dimensional parallelization (also partitioned in the vertical direction) is
applied. The HIP version of LICOM3 (LICOM3-HIP) is 42 times faster than the
same number of CPU cores when 384 AMD GPUs and CPU cores are used. LICOM3-HIP
has excellent scalability; it can still obtain a speedup of more than 4 on
9216 GPUs compared to 384 GPUs. In this phase, we successfully
performed a test of 1/20∘ LICOM3-HIP using 6550 nodes and
26 200 GPUs, and on a large scale, the model's speed was increased to
approximately 2.72 simulated years per day (SYPD). By putting almost all the
computation processes inside GPUs, the time cost of data transfer between CPUs
and GPUs was reduced, resulting in high performance. Simultaneously, a 14-year
spin-up integration following phase 2 of the Ocean Model Intercomparison
Project (OMIP-2) protocol of surface forcing was performed, and preliminary
results were evaluated. We found that the model results had little difference
from the CPU version. Further comparison with observations and
lower-resolution LICOM3 results suggests that the 1/20∘ LICOM3-HIP
can reproduce the observations and produce many smaller-scale activities, such
as submesoscale eddies and frontal-scale structures.

Abstract. Levee breach-induced flooding occurs occasionally but always causes considerable losses. A serious flood event occurred due to the collapse of a 15-m-long levee section in Qianbujing Creek, Shanghai, China, during typhoon "Fitow" in Oct, 2013. Heavy rainfall associated with the typhoon intensified the flood severity (extent and depth). This study investigates the flood evolution to understand the dynamic nature of flooding and the compound effect using a well-established 2D hydro-inundation model (Floodmap) to reconstruct this typical event. Our simulation results provide a comprehensive view of the spatial patterns of the flood evolution. The worst-hit areas are predicted to be low-lying settlement and farmland. Temporal evaluations suggest that the most critical time for flooding prevention is in the early hours after dike failure. In low-elevation areas, temporary drainage measures and flood defenses are equally important. The validation of the model demonstrates the reliability of the approach.

Abstract. Detailed characterization of the spatially and temporally varying inherent optical properties (IOPs) of sea ice is necessary to better predict energy and mass balances, as well as ice-associated primary production. Here we present the development of an active optical probe to measure IOPs of a small volume of sea ice (dm3) in situ and non-destructively. The probe is derived from the diffuse reflectance method used to measure the IOPs of human tissues. The instrument emits light into the ice by the use of optical fibre. Backscattered light is measured at multiple distances away from the source using several receiving fibres. Comparison to a Monte Carlo simulated lookup table allows to retrieve the absorption coefficient, the reduced scattering coefficient and a phase function similarity parameter γ, introduced by Bevilacqua and Depeursinge (1999), depending on the two first moments of the Legendre polynomials, allowing to analyze the backscattered light not satisfying the diffusion regime. Monte Carlo simulations showed that the depth cumulating 95% of the signal is between 40±2 mm and 270±20 mm depending on the source-detector distance and on the ice scattering properties. The magnitude of the instrument validation error on the reduced scattering coefficient ranged from 0.07% for the most scattering medium to 35% for the less scattering medium over the two orders of magnitude we validated. Vertical profiles of the reduced scattering coefficient were obtained with decimeter resolution on first-year Arctic interior sea ice on Baffin Island in early spring 2019. We measured values of up to 7.1 m−1 for the uppermost layer of interior ice and down to 0.15±0.05 m−1 for the bottommost layer. These values are in the range of polar interior sea ice measurements published by other authors. The inversion of the reduced scattering coefficient at this scale was strongly dependent of γ, highlighting the need to define the higher moments of the phase function. This novel developed probe provides a fast and reliable means for measurement of scattering into sea ice.

The objective of this article is to amplify the stories of female doctoral students and their passage through role conflicting periods of uncertainty and trauma. Specifically, this article highlights how the COVID-19 pandemic and racial unrest in the U.S. have impacted women pursuing doctorates in education. In addition to sharing personal reflections and experiences, the authors have outlined resources and recommendations for those who support doctoral students. Through the diverse perspectives of five students and one faculty member in the EdD in Higher Education Leadership program at Regis College, this article explores the lived experiences of second-year doctoral students during an incredible period of uncertainty. Douglas T. Hall’s model of coping serves to frame content around the many conflicting roles these students have been navigating and found to be exacerbated during the year 2020. This article seeks to empower leaders to re-envision approaches to support doctoral students through future crises and periods of uncertainty.
Trends and Challenges in Rural Homeless Populations

Background: Homelessness is a significant public health issue in the United States. Living in rural locations has been associated with an increase in poverty. Additionally, it has been found that veterans are at greater risk for homelessness than the general population. The aim of this research was to characterize rural homeless veterans and non-veterans living in Nebraska, United States.

Methods: A cross-sectional study was conducted comprising 50 veterans and 64 non-veterans recruited from rural locations in Nebraska. Fully structured interviews were conducted by the research staff that consisted of questions regarding participant sociodemographics, housing, clinical characteristics, psychosocial factors, and utilization of health care and social services.

Results: In comparison to non-veterans, rural homeless veterans were found to be older, more qualified, and more likely to have ever been married. Veterans spent fewer nights in a shelter and more nights in a halfway house. Regarding clinical features, veterans were more likely to report posttraumatic stress disorder and alcohol misuse. Veterans also reported shorter travel times to reach health care services and used them more often compared to non-veterans.

Conclusion: These findings suggest that homeless veterans and non-veterans within rural settings have unique needs to be addressed when it comes to providing health care and social services, as well as in attempts to eliminating homelessness. Further research will help in the development of improved methods to support rural veterans and non-veterans.

Background  

Finding that enrollment of Underrepresented in Medicine students at the Uniformed Services University of the Health Sciences was considerably below the national average, researchers sought to understand the experiences of minority students. The goal is to develop an academic and social support structure that sustains and attracts students of diverse backgrounds and races.

Method

Individual interviews of eight matriculated Black medical students and a focus group were conducted, with Institutional Review Board approval, to obtain feasible methodologies and implement change. Student's perspectives and experiences regarding their institution were investigated using qualitative thematic analysis.

 Results

The analysis revealed six themes from the individual interviews: Experience as a minority; Admission process; Difference in backgrounds; Curriculum culture; Diversity at the school; Military medicine. The overarching message from the students was “If you don’t see yourself represented somewhere, it’s hard to believe that you belong.” The focus group made four recommendations: Add a minority viewpoint to curriculum; Add textbooks that portray black skin; Collaborate with Historically Black Colleges and Universities; Increase recruitment of Black students and faculty. 

Conclusion

It is hard for minority students to believe they belong in environments without the representation and infrastructure needed to support their unique needs. Implementing ideas, such as those described in this report, is an important step towards creating inclusion and equity.

Today people all over the world live in a multilingual environment. Our country did not stay away from this global process. One of the priorities of the socio-economic development of the Republic of Kazakhstan is the possession of three languages ​​by the people of Kazakhstan. Since independence, we have focused on establishment of political, social, economic and cultural ties with many countries of the world.
The importance of language for the effectiveness of these relations and the development of the unity of the country and people is growing day by day. Multilingualism is one of the most important needs of today, allowing the younger generation fly freely in the educational space, explore the secrets of world science and show your ability. Therefore, the role, prestige and scale of the three languages ​​in the implementation of the trilingual policy in the country require close attention. Otherwise, there may be confusion in the positioning of each language. This is confirmed by the fact that criticisms are already being introduced into the implementation of this language policy. Multilingualism has emerged in accordance with modern requirements for teaching and working in English.
