Authors: Truong Le Cong
Published: September 2020

This study aims to determine the blood sugar-lowering effect of Melastoma malabathricum L. infusion on Mus musculus. The research design used was an experimental laboratory carried out in the pharmacology laboratory of the Ho Chi Minh City University. This study used 15 male mice which were divided into 5 groups consisting of group I as negative control by giving aquadest, groups II, III, IV were given infusion of Melastoma malabathricum L. respectively 0.1 g/ml, 0.2 g/ml, and 0.4 g/ml, and group V as a positive control with glibenclamide suspension. The results showed that statistical testing using the SPSS program showed a significant difference (p <0.05), which means that senggani leaf infusion had a significant effect on reducing blood sugar levels in mice and the most optimal was 0.4 g/ml infusion.
Menstrual Cycle in Female Workers
Authors: Huong Nguyen Thu
Published: September 2020

Menstrual disorders are abnormalities that occur in the menstrual cycle. There are various menstrual disorders that women can experience, ranging from too little or too much menstrual blood, painful menstruation, to depression before menstruation or premenstrual dysphoric disorder. Physical activity is divided into three levels, namely light, moderate and heavy physical activity. Physical activity of heavy intensity can cause physiological disorders of the menstrual cycle. presence of menstruation (amenorrhoea), thinning of the bones (osteoporosis), menstrual irregularities or intermenstrual bleeding, abnormal growth of the uterine wall, and infertility.

Authors: Jaworski Janusz , Lech Grzegorz , Ambroży Tadeusz , Żak Michał
Published: September 2020

Purpose

The main aim of this study was to evaluate the effect of coordination motor abilities on the sports skill level in elite male badminton players.

Methods

The study group consisted of 12 male players from the Polish national badminton team. the scope of the research included measurement of basic anthropometric features and selected coordination motor abilities. Using the spearman’s rank correlation coefficient, statistically significant cause and effect relations were identified between the sports skill level and the analysed coordination abilities. Multiple determination coefficients were computed to analyse the impact of individual coordination abilities on the sports skill level.

Results

The multiple determination coefficients showed that the sports skill level of the badminton players was most strongly determined by spatial orientation (ca. 42%), followed by frequency of movements (28%) and kinaesthetic differentiation (ca. 17%).

Conclusions

It seems that these coordination abilities should be taken into careful consideration in technical and tactical training of badminton players since they largely determine their level of achievement.

Published: September 2020

Purpose

Vertebral haemangiomas are incidental findings in imaging modalities. Atypical haemangiomas are haeman­giomas rich in vascular tissue, and they are found to be hypointense in T1 sequences and hyperintense in T2 sequences, mimicking the findings of metastatic lesions. In the present study we aim to evaluate the ability of diffusion- weighted imaging to differentiate these two groups of vertebral lesions.

Material and methods

In the present cross-sectional study, a total of 23 lesions were included, including 10 haemangiomas and 13 malignant lesions. Diffusion-weighted imaging was used to compare atypical haemangiomas and metastatic lesions. The apparent diffusion co-efficient was determined for each lesion, and then the mean of each group was calculated. The means were then compared. Receiver operating characteristic analysis was used to determine a cut-off ADC value to differentiate these lesions.

Results

The difference between the mean age of the two groups was not significant. The mean ADC value for atypical haemangiomas was 1884 ± 74 × 10-6 mm2/s and 1008 ± 81 × 10-6 mm2/s for the malignant lesions. The difference between the two groups was statistically significant (p < 10-3). ROC curve analysis determined an ADC value of 958 × 10-6 mm2/s to be able to differentiate between atypical haemangiomas and malignant lesions.

Conclusions

Diffusion-weighted MRI could be used to differentiate between atypical haemangiomas and malignant metastatic lesions.
The relationship between periodontal status and rheumatoid arthritis – systematic review
Authors: Samborska-Mazur Joanna , Sikorska Dorota , Wyganowska-Świątkowska Marzena
Published: September 2020

There have been numerous publications investigating the relationship between periodontitis (PD) and rheumatoid arthritis (RA) so far.

This publication presents the common risk factors for the development of PD and RA. The major impact of the pathological bacterial factor and cigarette smoking with chronic inflammation playing the key role in both diseases has been confirmed by numerous studies in various populations over the years. More research focuses nowadays also on the role of improper diet and obesity. Pathophysiological pathways, such as increased concentration of proinflammatory cytokines, indirectly affecting the cardiovascular complications and coagulation disorders, which has an impact on function disorders of tissue metalloproteinase inhibitors and the plasminogen activation system, were also researched.

This systematic review of current literature has shown numerous discrepancies in previous analyses and the need for further detailed research on the relationship between periodontal status and RA.
Mikulicz’s disease and Küttner’s tumor as manifestations of IgG4-related diseases: a review of the literature
Authors: Kamiński Bartłomiej , Błochowiak Katarzyna
Published: September 2020

According to a new concept for the classification and division of autoimmune diseases, Mikulicz’s disease and Küttner’s tumor belong to immunoglobulin G4-related diseases (IgG4-RD) and fulfil their diagnostic criteria. The aim of this study was to summarize the new classification concepts of IgG4-RD in the head and neck area and to review their clinical, histopathological and serologic criteria and the methods used in the diagnostic workup with respect to their advantages, limitations and differentiative value.

The PubMed, Web of Science, Google Scholar, and Scopus databases were searched for articles published between 2009 and 2019 using the following key words: IgG4-related diseases, Mikulicz’s disease, Küttner’s tumor, salivary glands, xerostomia.

Results of the review of the literature revealed that Mikulicz’s disease and Küttner’s tumor fulfil the same diagnostic criteria but may manifest different clinical symptoms which determine the choice of the different diagnostic tools.
Kikuchi-Fujimoto disease associated with primary Sjögren’s syndrome – literature review based on a case report
Authors: Wiśniewska Katarzyna , Pawlak-Buś Katarzyna , Leszczyński Piotr
Published: September 2020

Primary Sjögren’s syndrome (pSS) is a chronic, autoimmune disease predominantly involving exocrine glands. Lymphadenopathy is one of the possible symptoms of pSS. It may also suggest development of non-Hodgkin lymphoma (NHL), the most severe complication of pSS, or be a symptom of less common diseases, such as Kikuchi-Fujimoto disease (KFD), presented in this paper. Kikuchi-Fujimoto disease is an extremely rare, benign and self-limiting disorder, characterized by regional lymphadenopathy.

This paper presents a case of previously unreported association of pSS, KFD and renal cancer in a patient with recurrent cervical lymphadenopathy, as well as a discussion on the coexistence of these diseases based on available literature searching for PubMed, Scopus and Google Scholar databases, particularly in this subject. These three clinical entities may manifest lymphadenopathy each, causing a diagnostic dilemma. The treatment is also challenging under such circumstances. In this particular situation, it was a combination of immunosuppressive therapy and surgery.
Working for the Machine: Patronage Jobs and Political Services in Argentina
Authors: Oliveros Virginia
Published: September 2020

Conventional wisdom posits that patronage jobs are distributed to supporters in exchange for political services. But why would public employees comply with the agreement and provide political services after receiving the job? Departing from existing explanations, I argue that patronage
employees engage in political activities because their jobs are tied to their patrons' political survival. Supporters' jobs will be maintained by the incumbent, but not by the opposition. Supporters, then, have incentives to help the incumbent, which makes their original commitment to provide
political services a credible one. Using survey experiments embedded in a survey of 1,200 Argentine public employees, I show that patronage employees are involved in political activities and that they believe their jobs are tied to the political success of the incumbent.
Time and tide: pendulum clocks and gravity tides
Authors: Agnew Duncan C.
Published: September 2020

Abstract. Tidal fluctuations in gravity will affect the period of a pendulum and hence the timekeeping of any such clock that uses one. Since pendulum clocks were, until the 1940s, the best timekeepers available, there has been interest in seeing if tidal effects could be observed in the best performing examples of these clocks. The first such observation was in 1929, before gravity tides were measured with spring gravimeters; at the time of the second (1940–1943), such gravimeters were still being developed. Subsequent observations, having been made after pendulum clocks had ceased to be the best available timekeepers and after reliable gravimeter measurements of tides, have been more of an indication of clock quality than a contribution to our knowledge of tides. This paper describes the different measurements and revisits them in terms of our current knowledge of Earth tides. Doing so shows that clock-based systems, though noisier than spring gravimeters, were an early form of an absolute gravimeter that could indeed observe Earth tides.
EXPLORING SCHEMES FOR VISUALIZING URBAN WIND FIELDS BASED ON CFD SIMULATIONS BY EMPLOYING OGC STANDARDS
Authors: Schneider S. , Santhanavanich T. , Koukofikis A. , Coors V.
Published: September 2020

Abstract. In this paper various schemes for visualizing geo-spatial data such as Computational Fluid Dynamics (CFD) data are explored. The architecture of a new Smart Cities Platform is presented and examples of the visualization capabilities are given. Results show that scalar and vectorial measurands, such as wind pressure and wind directions, may be presented using the same schemes, however, interpretation of the visualization varies between measurands. A hex-grid representation of the highly dense point cloud data yields easier interpretation of the scene as do streamlines for visualizing a path of flow over and around buildings. Results of performance evaluations suggest that the same visualisation scheme (e.g. hex-grid) but different data formats, yields faster loading times when using 3D Tiles rather than GeoJSON and an overall smoother interaction within the application.
Trends in social vulnerability to storm surges in Shenzhen, China
Authors: Yu Huaming , Shen Yuhang , Kelly Ryan M. , Qi Xin , Wu Kejian , Li Songlin , Yu Haiqing , Bao Xianwen
Published: September 2020

Abstract. An evaluation of social vulnerability to storm surges is important
for any coastal city to provide marine disaster preparedness and mitigation
procedures and to formulate post-disaster emergency plans for coastal
communities. This study establishes an integrated evaluation system of
social vulnerability by blending a variety of single-evaluation methods,
which are subsequently combined by weighting in order to calculate a common
social vulnerability index. Shenzhen has a current reputation of having considerable economic development potential and is a representative city
in China. It is chosen for an evaluation of its social vulnerability to
storm surges via a historical social and economic statistical dataset
spanning the period 1986–2016. Exposure and sensitivity increased slowly
with some fluctuation, leading to some alterations of the social
vulnerability trend. Social vulnerability stayed almost constant during
1986–1991 and 1993–2004, while it decreased sharply afterwards to form a
“stair-type” declining curve over the past 31 years. Resilience is
progressively increasing by virtue of a continuous increase in medical
services supply, fixed asset investments, and salary levels of employees.
These determinants contribute to the overall downward trend of social
vulnerability for Shenzhen.
Analyses of Peace River SWIPS data and its implications for the roles played by frazil ice
and in situ anchor ice growth in a freezing river
Authors: Marko John R. , Topham David R.
Published: September 2020

Abstract. Peace River SWIPS (Shallow Water Ice Profiling Sonar) data were analyzed to assess and quantify the roles of frazil ice suspensions and riverbed anchor ice grown in situ during the initial buildup of a seasonal ice cover. Data were derived from quasi-continuous monitoring of frazil parameters throughout the water column to provide direct and indirect measures of anchor ice volume and mass growth rates. Analyses utilized water level and air and water temperature information and directly measured acoustic volume backscattering coefficients to track and interpret spatial and temporal changes in riverbed and water column ice constituents. Interests were focused on 4 specific frazil intervals characterized by anomalously low levels of frazil content (relative to simulations with an anchor ice-free river ice model) distinguished by two strikingly different types of time dependences. A simple physical model was proposed to quantitatively account for discrepancies between measured and simulated results in terms of the pronounced dominance of anchor ice as an initial source of river ice volume and mass. The distinctive differences in temporally variable water column frazil content are attributed, in this model, to corresponding differences in the stabilities of riverbed anchor ice layers against detachment and buoyancy-driven movement to the river surface. In accord with earlier observations, the stability of in situ grown riverbed ice layers appears to be inversely proportional to cooling rates. The strength of the coupling between the two studied ice species was shown to be strong enough to detect changes in the anchor ice constituent from variations in water column frazil content.

Published: September 2020

Introdução: A cinarizina é amplamente prescrita para desordens vestibulares. Não há monografia para avaliar a qualidade dos comprimidos nas farmacopeias. Objetivo: Desenvolver métodos para avaliar a qualidade de comprimidos referência (R), genérico (G), e similar (S) de cinarizina. Métodos: Para o doseamento, foi validado um método por espectrofotometria no UV. R, G e S foram submetidos aos ensaios gerais de controle de qualidade. Para a dissolução, foi determinada a solubilidade do fármaco em pH 1,2, 4,5 e 6,8. Na validação comparou-se a performance dos aparatos pá (velocidades 50 e 75 rpm) e cesta (50 e 100 rpm) na dissolução de R, G e S. Resultados: O doseamento foi validado e mostrou-se preciso, exato, linear, robusto e específico. R, G e S apresentaram conformidade no doseamento, peso médio, dureza, friabilidade, desintegração e, uniformidade. O método de dissolução demonstrou linearidade, precisão, exatidão e especificidade em pH 1,2. A dissolução de R, G e S foi maior que 70% em 30 minutos. O aparato pá a 75 rpm é a condição que discrimina melhor as formulações, pois nessa condição G e S não são equivalentes farmacêuticos ao R. Conclusão: Os métodos desenvolvidos apresentam a confiabilidade requerida para uma análise farmacopeica.

This is the third in a planned series of data papers presenting modelled vector distributions produced during the ECDC and EFSA funded VectorNet project. The data package presented here includes those Culicoides vectors species first modelled in 2015 as part of the VectorNet gap analysis work namely C. imicola, C. obsoletus, C. scoticus, C. dewulfi, C. chiopterus, C. pulicaris, C. lupicaris, C. punctatus, and C. newsteadi. The known distributions of these species within the Project area (Europe, the Mediterranean Basin, North Africa, and Eurasia) are currently incomplete to a greater or lesser degree. The models are designed to fill the gaps with predicted distributions, to provide a) first indication of vector species distributions across the project geographical extent, and b) assistance in targeting surveys to collect distribution data for those areas with no field validated information. The models are based on input data from light trap surveillance of adult Culicoides across continental Europe and surrounding regions (71.8°N –33.5°S, – 11.2°W – 62°E), concentrated in Western countries, supplemented by transect samples in eastern and northern Europe. Data from central EU are relatively sparse. Funding statement: This work was carried out with support from the VectorNet framework contract OC/EFSA/AHAW/2013/02-FWC1 funded by the European Centre for Disease prevention and Control (ECDC) and the European Food Safety Agency (EFSA) and the PALE-Blu H2020 Project ID: 727393.
Real-time air pollution (PM2.5) measurements in Education City, Doha, Qatar: Evaluating data from two different photometric monitors
Authors: Zhai Kevin , Bhatti Mohammad , Khalil Omar , Khalil Laila , Al-Hail Moza , Yousef Mohammad S
Published: September 2020

Background: Given the health hazards posed by particulate matter 2.5 (PM2.5), the need exists for simple, cost-effective, and real-time methods to monitor air quality with high spatio-temporal resolution. Direct-reading photometric detection is one modality of real-time PM2.5 monitoring. However, photometric data often require post hoc correction factors specific to individual manufacturers, meteorological conditions, and particle sizes and compositions. Methods: We methodically compared and evaluated PM2.5 concentration values collected by two different photometric monitors (TSI Environmental Monitor 8540 and MetOne ES-642) in Education City, Doha, Qatar. We analyzed the data collected by the two monitors in two different locations in September and December 2019, and side-by-side for two weeks in February 2020. Correlation and linear regression analyses were conducted to determine correction factors between the two monitors. Results and Discussion: The results indicate that both monitors reported almost identical trends in PM2.5 concentration, while the TSI monitor exaggerated the values by approximately twofold. When correlation-based corrections were applied, data from the two monitors matched almost perfectly for all comparison periods. As correction factors between PM2.5 sensors may vary based on in situ conditions, calibration must therefore be conducted on a case-by-case basis. However, our methodologies could constitute a template for future development of cross-calibration strategies. In addition, we determined average PM2.5 concentrations in Education City for each study period. These values were lower than those previously reported for other locations in Qatar during similar seasons. Conclusions: Our findings emphasize the relevance of the microenvironment when assessing PM2.5 levels for public health purposes. This investigation is expected to support and inform air quality management and mitigation strategies.

O conhecimento sobre microbiologia e parasitologia é considerado abstrato, pois muitos agentes causadores de doenças não são vistos a olho nu, o que distancia os alunos da realidade. Assim, nossos objetivos foram promover ações educativas por meio de ferramentas didáticas lúdicas que possibilitassem a complementação do aprendizado dos alunos frente aos diferentes grupos de microorganismos e parasitos e das ações de profilaxia relacionadas aos mesmos, e avaliar se ao final eles tinham condições de discriminar os grupos e relacionar com as doenças e as formas de profilaxia. Para tanto, foram feitas entrevistas junto aos professores para levantamento das possíveis atividades a serem desenvolvidas. A ação foi definida e então dividida em três momentos (aula expositiva, jogo didático e mostra científica) realizados entre agosto e novembro de 2018, atingindo aproximadamente 350 alunos, de oitavos e nonos anos, de três escolas públicas da zona urbana e rural da cidade de Uberlândia-MG. Para avaliar o impacto da ação foi feita uma análise comparativa de questionários aplicados antes (pré-intervenção) e após a ação (pós-intervenção). O percentual das respostas corretas nos questionários pós-intervenção aumentou em duas escolas (p>0,005). Quanto à análise por questões, as menores porcentagens de acertos foram observadas em perguntas relacionadas à distinção entre doenças bacterianas e virais, o reconhecimento dos sintomas e a associação das formas de transmissão com a profilaxia. Assim, este estudo reforça a importância da educação em saúde para que os alunos se mobilizem frente ao combate das doenças
Análise da produção científica internacional em contabilidade aplicada ao setor do agronegócio

Published: September 2020

O objetivo da pesquisa é analisar o perfil da produção científica em contabilidade aplicada ao setor do agronegócio, à luz da Lei de Lotka. Foram coletados trabalhos em cinco bases de dados: Emerald, Scopus, Web of Science, SciELO e ScienceDirect. No total de 106 documentos coletados, foram analisados: i) quantidade de trabalhos produzidos por autor; ii) vínculo institucional dos autores; iii) tipo de documento produzido; e iv) temas abordados em subáreas pré-definidas. Concluiu-se que a produção científica na área tem crescido nos últimos 10 anos (2007-2017), principalmente em temas que permeiam a discussão acerca dos ativos biológicos e custos do agronegócio. As revistas científicas identificadas com o maior número de contribuições foram Custos e Agronegócio On line, Agricultural Finance Review e Agribusiness, sendo que o periódico brasileiro apresentou uma maior quantidade de produção científica, destacando, assim, a importância que o País, de caráter exportador, tem frente ao setor de agronegócios. Entretanto, os autores mais prolíficos destacados não são brasileiros; o fato pode ser evidenciado pela escassez da quantidade de produção de autores brasileiros que publicam várias vezes no tema ou poucos autores brasileiros publicam em inglês. Sobre a produtividade dos autores, a máxima de Lotka (1926) pôde ser observada; entretanto, quando analisado o método empírico de ajustamento ao inverso quadrado proposto por Pao (1985), os coeficientes que representam a relação de produtividade dos autores distanciaram-se da Lei de Lotka. A relação estatística foi verificada através do teste Kolmogorov-Smirnov (K-S); os resultados desta pesquisa apontam a aceitação da hipótese nula a 0,01 de nível de significância. Para aceitação da hipótese alternativa, o Dmáx deveria ser menor que o valor crítico, porém, a especificidade da temática, com a presença de poucos artigos na área, aumenta o valor crítico, resultando na rejeição da mesma.
A umbanda e os processos de saúde-doença
Authors: Silva Luciana Macedo Ferreira , Scorsolini-Comin Fabio
Published: September 2020

O envolvimento em atividades de cunho religioso pode constituir uma estratégia de enfrentamento diante das demandas de saúde-doença. No Brasil, a umbanda destaca-se como religião fortemente associada aos processos de cura, sendo procurada por fiéis de diferentes filiações religiosas. O objetivo deste estudo foi compreender como os processos saúde-doença são interpretados nos estudos científicos que possuem como cenário a umbanda. Trata-se de uma revisão integrativa nas bases/bibliotecas Lilacs, SciELO, PePSIC, PsycINFO e Medline (2007 a 2018). Por meio da aplicação dos critérios de inclusão/ exclusão por dois juízes independentes, foram recuperados 22 estudos na íntegra. A partir dos sentidos disponíveis nessas publicações, pode-se afirmar que, na umbanda, os processos de saúde-doença são identificados como forma de remissão e resgate dos resquícios de vidas passadas, como influências de energias externas do universo espiritual, ou ainda como forma de merecimento pessoal. O tratamento espiritual foi referido neste corpo de literatura como meio complementar à medicina tradicional, fortalecendo uma perspectiva de saúde-doença que integra aspectos biológicos, psicológicos e culturais tanto na compreensão do adoecimento como nos itinerários terapêuticos.
O cuidado materno violento: reflexões psicanalíticas sobre a Síndrome de Munchausen por Procuração
Authors: Tachibana Miriam , Ferreira Guilherme Dantas
Published: September 2020

A Síndrome de Munchausen por Procuração caracteriza-se pela simulação ou produção de sintomas no corpo da criança, o que faz com que ela seja submetida a tratamentos médicos desnecessários. Como geralmente a perpetradora é a mãe, a síndrome tem sido associada à violência intrafamiliar. Com o objetivo de aprofundar a compreensão psicológica dos envolvidos neste quadro peculiar, foi realizada uma análise do documentário “Mamãe morta e querida”, à luz das contribuições do psicanalista Donald Winnicott, Fazendo uso do método psicanalítico, os pesquisadores consideraram interpretativamente as manifestações das pessoas entrevistadas no documentário, organizando reflexões sobre os familiares e profissionais e sobre a dupla mãe-filha em dois eixos temáticos. Com base neles, discutiu-se: 1) que a mãe perpetradora desperta profunda revolta nos familiares e profissionais, o que lhes impede de considerar algo além da maldade materna; 2) que a relação entre mãe-filha parece ser marcada pela incapacidade de diferenciação, o que deveria ser o foco de cuidado com a dupla, em vez das doenças falsas apresentadas. Espera-se que este estudo contribua para que os profissionais da saúde tenham condições de intervir com uma postura mais inclusiva.

Vilanova Artigas: a poética traduzida
Authors: Gabriel Marcos Faccioli
Published: September 2020

Abordamos aqui a obra do influente e controvertido arquiteto Vilanova Artigas, ativo em São Paulo entre as décadas de 1940 e 1970, como obra de arte autônoma, pois esta mostra um uso figurativo de estruturas trilíticas de concreto armado, o qual operava uma fusão da linearidade dos membros com a criação volumétrica no mesmo material. Seus projetos mostravam, por um lado, uma disposição volumétrica e estrutural serial ao longo de um eixo e, por outro, a alternância no percurso do observador entre massa cerrada e espaço, entre luzes intensas e sombras profundas, entre peso e resistência, contrastes estes que a tradição atribui ao sublime arquitetônico, à visão do drama humano do trabalho que, afinal, ergue as estruturas além da medida razoável da utilidade. Exceder esta medida põe a obra em conflito com o marxismo do militante Artigas, mas também a põe no terreno da arquitetura moderna enquanto “estilo da modernidade”, em conflito, segundo Reyner Banham (1970, p.327), com o desenvolvimento ininterrupto da técnica com a qual pretendia legitimar-se.
Testing the Effectiveness of Altman and Beneish Models in Detecting Financial Fraud and Financial Manipulation: Case Study Kuwaiti Stock
Authors: Akra Raif M. , Chaya Jamil K.
Published: September 2020

This study is an adoption of two probabilistic financial analysis methods, Altman and Beneish Models that have proven effective in early detection of possible financial distress and profit manipulation respectively. Motivated by the effectiveness of the models, this paper applies the methodology on the Kuwaiti Stock Market excluding banking and insurance companies. Results demonstrated that Altman has less predictive power in the context of industrial and real estate companies while Beneish has a strong predictive power to uncover possible manipulation in earnings or fraudulent reporting in the tested companies as confirmed with an ex-post review of the companies and news sources. We recommend a recalibration of the Altman model according to industry in addition to recommending that financial analysts and interested parties use both models.
Coronaspeak as Key to Coronaculture: Studying New Cultural Practices Through Neologisms
Authors: Alyeksyeyeva Iryna O. , Chaiuk Tetyana A. , Galitska Elizaveta A.
Published: September 2020

The research explores neologisms that have entered everyday English discourse during the coronavirus pandemic and formed so-called Coronaspeak. The analysis reveals that three approaches to neologisms are applicable to lexemes of Coronaspeak: the stylistic theory that is relevant to the words that used to be scientific terms but have been adopted by non-specialists, the etymological approach that regards as neologisms those new coinages that have developed a new meaning, and the denotational approach where neologisms are the lexemes created to nominate new concepts. Drawing on the assumption that language units verbalise cultural phenomena, the further study of Coronaspeak suggests that the modern English-speaking societies undergo a number of cultural changes: medicalisation of public discourse that originates from the government policy to engage the public in the struggle against COVID-19 as well as from using the pandemic as an argument in ideological and political conflicts; conceptualisation of the pandemic as a milestone, a turning point in history; introduction of new categories for social groups based on such criteria as health, profession, or attitude to the pandemic and socially responsible behaviour (e.g., clinically vulnerable people, key workers, covadults); development of new or modification of old cultural practices that embrace lifestyle (coronacocooing, WFH, drivecation), appearance (corona hair, coronabesity), patterns of online and offline communication (homeference, video party, coronadating, Wuhan shake); reconceptualisation of pre-pandemic concepts (home), and, finally, emergence of new types of interpersonal relations (coronarelationship, corona boyfriend).

The purpose of this research was to investigate the relationship between teachers’ fear of missing out (FoMO) levels and their cyberloafing behaviour and to reveal whether teachers’ FoMO and their cyberloafing behaviour differ according to their gender. The sample of the research consisted of 702 secondary school teachers working in state schools within the borders of Istanbul in 2019-2020 education year. According to the research, it was identified that the level of teachers’ FoMO levels and cyberloafing behaviours were moderate. It was detected that teachers’ FoMO levels differed significantly according to gender. With this result, male teachers’ FoMO levels were higher than female teachers’ FoMO levels. Similarly, it was observed that there was a significant difference between teachers’ cyberloafing behaviour and gender. According to this result, it was found that male teachers’ mean score of cyberloafing behaviour was higher than female teachers’ mean score of cyberloafing behaviour in all sub-scales. In addition, a positive significant relationship between teachers’ FoMO and their cyberloafing behaviour was observed.

Kan een non disclosure agreement worden ontbonden?

Het in handelsrelaties contractueel verankeren van geheimhouding ter zake van bedrijfsgeheimen is als gevolg van de Wet bescherming bedrijfsgeheimen belangrijk(er) geworden. Partijen kunnen in de regel kiezen voor een NDA of een geheimhoudingsbeding in een meeromvattende overeenkomst. De schending van een geheimhoudingsverplichting zal in rechte veelal moeilijk zijn aan te tonen en ontbinding van de NDA wordt vaak uitgesloten. Toch onderzoeken de auteurs de juridische kwalificatie van de NDA en de gevolgen hiervan met betrekking tot de mogelijkheden tot ontbinding. Zij betogen dat een NDA veelal zal kwalificeren als een obligatoire overeenkomst, maar niet als een wederkerige overeenkomst, waardoor een NDA in geval van een tekortkoming niet kan worden ontbonden. De rechtsgevolgen van ontbinding zouden volgens de auteurs sowieso beperkt zijn geweest. In het geval vertrouwelijkheid is gewaarborgd in de vorm van een geheimhoudingsbeding in een meeromvattende overeenkomst, ligt dit anders. Gezien de verstrekkende rechtsgevolgen die een ontbinding in dat geval kan hebben, betogen auteurs dat het goed is dat de opstellers van contracten zich hier bewust van zijn.

De rechtvaardiging van tussentijdse ontbinding

Aan de hand van ECLI:NL:GHSHE:2019:4535 (TsZ/Alert) wordt gekeken naar de rechtvaardiging van tussentijdse ontbinding op grond van schending van een material obligation en een anticipatory breach (art. 6:80 BW), en de verhouding tussen gevorderde terugbetaling en een exoneratiebeding.
A Comparative Investigation of Assessment Practices in Distance and Online Learning Undergraduate Mathematics in Nigeria
Authors: Reju Comfort O , Jita Loyiso C
Published: September 2020

We investigate and compare assessment practices in two (dual- and single-mode) institutions in Nigeria. A mixed-methods approach was employed. Descriptive statistics and narration were carried out for the purpose of determining what the assessment practices were and how they may be related to the students learning of undergraduate mathematics in distance and online education. Results show that there are similarities and variations in assessment practices that shaped open and distance learning practices in these universities. This suggests a need for careful review of assessment practices aimed at improving students’ engagement and learning for outstanding undergraduate mathematics learning experiences.
Factors Potentially Influencing Discipline Referral and Suspensions at an Affiliated Charter High School
Authors: Bryant Debra , Wilson Andrea
Published: September 2020

This article addresses long-standing data from federal government agencies documenting concerns regarding the use of school discipline and suspension indicating that Black students are referred for discipline and/or suspended at a higher rate than students of other ethnicities. Available data from a local school district reflected similar troubling patterns of discipline referral and suspension. The purpose of this study was to determine if variables such as students’ ethnicity, socioeconomic status, and gender predicted the likelihood of receiving discipline referrals or being suspended at an affiliated charter high school in a local school district. Guided by Bandura’s social learning theory and Skinner’s behaviorism, this correlational explanatory quantitative study examined archival school discipline data for 2,536 students enrolled (n = 1,570 students who received at least one discipline referral or suspension) during the 2013–2014 school year at a local high school. Binomial logistic regression results showed that Black students from low socioeconomic backgrounds were significantly more likely to be suspended compared to other ethnicities. Negative binomial regression analysis indicated students who were Black, male, and were from low socioeconomic backgrounds were at significantly greater risk of receiving a referral than other ethnicities. These results suggest that by investigating school discipline patterns, disproportionality can be identified and later addressed in a manner that respects the unique needs of all students.
Mission Unaccomplished: Beyond “Talk[ing] a Good Game” To Promote Diversity and Inclusion
Authors: Lehan Tara , Hussey Heather , Babcock Ashley
Published: September 2020

Guided by feminist standpoint theory and scholars’ calls to move beyond merely counting individuals to understand the extent to which higher education institutions are diverse, the authors invited faculty members, staff members, and administrators from minoritized groups to describe their perceptions and experiences, including those associated with diversity and inclusion efforts at their institutions. In association with various dynamics, these individuals frequently described such initiatives as mostly talk with little to no meaningful objectives and outcomes. Based on these findings, we provide a three-step process that can be followed to disrupt and dismantle systems of (dis)advantage to promote greater diversity and inclusion.
Predicting International Student Enrollment in U.S. Institutions by Institutional Characteristics: Using Fixed and Random Effects
Authors: Bicak Ibrahim , Taylor Z. W.
Published: September 2020

For the first time, international student enrollment in U.S. institutions of higher education declined for a second straight year in 2017–2018. As a result, we sought to understand which institutional characteristics predict international student enrollment, informing the international education community regarding possible institutional factors responsible for the decline in international student enrollment by using five-year panel data from 2013 Fall to 2017 Fall. Results from institutional fixed effects models revealed positive relationships between first-time international undergraduate enrollment and different variables such as institutional grant aid in bachelor’s institutions and student services expenses at private non-profit institutions in suburban settings. Contrary to earlier research, this study’s findings revealed that there is no relationship between state appropriations and first-time international undergraduate enrollment. We address implications for research, practice, and international student choice.
Supporting Science Learning For English Language Learners

Published: September 2020

This study focused on two fourth-grade science classrooms with English learners (ELs), exploring how teachers supported students’ science and language/literacy learning in different language contexts. Three a priori research-based practices recommended for supporting science learning framed our exploration: (a) negotiation, opportunities for individual and social construction and critique of knowledge; (b) embedded language, opportunities for language and literacy learning as a natural aspect of science; and (c) non-threatening learning environments, opportunities for social apprenticeship and interaction. We provide insights into how science instructional practices supported ELs’ science and language learning. One key implication is that enacting these three principles of practice in students’ first language (Spanish), when less linguistic scaffolding is required, creates more opportunities to focus on disciplinary content and exploration of students’ ideas. The second key implication is that using open-ended questions and extending prompts and questions through exploration-based lessons was an effective way to support and guide ELs (and all students) to rich understandings of key concepts. A third key implication is that although teachers delivered instruction in two different languages, when they enacted these principles, they fostered student engagement and interest in science. Effective implementation of these practices outweighed the language of delivery.
School Counselors’ Response to School Shootings: Framework of Recommendations
Authors: Brown Carleton H
Published: September 2020

Despite the many expectations of school counselors in responding effectively to crisis situations, there is a lack of research and comprehensive standards that address best practices for school counselors in terms of preparing for and responding to a school shooting. Using federal guidelines and crisis literature, including studies focused on school counselors’ lived experiences of a school shooting, the author offers a research-informed theoretical framework of recommendations at different phases of a school shooting. The framework of recommendations points out probable hindrances to school counselors’ decision making. School counselors’ awareness of these impediments before experiencing each phase of such a crisis would be of benefit to them. School counselors may also use the framework of recommendations to help them assess their developmental needs in relation to preparing for and responding to a school shooting crisis.

Design and seal performance analysis of bionic sealing ring for dynamic seal
Authors: HU Yang , ZHANG Jie , CHEN Li Ming
Published: September 2020

In this paper, the non-smooth surface technology is applied to the surface structure of the rectangular sealing ring, and a bionic sealing ring is designed. Two-dimensional axisymmetric models of rectangular and bionic sealing rings were established. Effects of pre-compression amount, fluid pressure, friction coefficient and reciprocating velocity on the static and dynamic sealing performance of two sealing rings were studied. The results show that the seal performance of the bionic sealing ring is greater than that of rectangular. The static seal performance increases with the increasing of fluid pressure and compression amount. Dynamic sealing performance in outward stroke is better than it in the inward stroke. Friction coefficient has a smaller effect on the bionic sealing ring’s sealing performance than rectangular sealing ring. Therefore, using the bionic sealing ring can improve the static and dynamic seal performances and prolong its service life in hydraulic systems, rotating machinery and reciprocating machinery.

Published: September 2020

This paper presents experimental, numerical and analytical analysis of newly cast and pre-cracking flexural reinforced concrete beams strengthened with CFRP. In total, 9 intermediate-scale composite beams were cast and tested using 4-point bending test setup. Midspan deflection, width of the cracks, concrete and CFRP strains were measured during the experimental program. Clear efficiency of composite pre-cracked beams was observed in comparison to newly cast beams: enhanced flexural capacity and increased stiffness after appearance of primary cracks in tension zone. Good agreement was found comparing experimental and theoretical (EC2) deflections of RC beams strengthened with CFRP. However, for more detailed verification, the analysis should be extended with more specimens. The shear stress at the end of CFRP sheets between the concrete and CFRP increased rapidly until reaching maximum slip value, when the reinforced concrete beam strengthened with CFRP reaches 60-90 % utilization of load bearing capacity. All experimental results were compared with numerical and analytical calculations. Experimental, numerical and analytical results were in sufficiently good agreement.
