Antibody therapeutics for the treatment of COVID-19 has been highly successful while faces a challenge of the recent emergence of the Omicron variant which escapes the majority of existing SARS-CoV-2 neutralizing antibodies (nAbs). Here, we successfully generated a panel of SARS-CoV-2/SARS-CoV cross-neutralizing antibodies by sequential immunization of the two pseudoviruses. Of which, nAbs X01, X10 and X17 showed broadly neutralizing breadths against most variants of concern (VOCs) and X17 was further identified as a Class 5 nAb with undiminished neutralization against the Omicron variant. Cryo-EM structures of three-antibody in complex with the spike proteins of prototyped SARS-CoV-2, Delta, Omicron and SARS-CoV defined three non-overlapping conserved epitopes on the receptor-binding domain (RBD). The triple antibody cocktail exhibited enhanced resistance to viral escape and effective protection against the infection of Beta variant in hamsters. Our finding will aid the development of both antibody therapeutics and broad vaccines against SARS-CoV-2 and emerging variants.
Popular approval of Covid-19 restrictions is strongly correlated with vaccination rate
Authors: Jucker Jean-Luc
Published: February 2022

Most governments in the world have implemented restrictive measures to fight against the Covid-19 pandemic. Little is known, however, on people’s approval or disapproval of these restrictions, and importantly, on the factors that might contribute to approval. Switzerland might be the only country where citizens voted on Covid-19 restrictive measures by referendum, thereby providing a rare opportunity to assess the extent to which people approve Covid-19 restrictions. Using data from the Swiss authorities, we find that the percentage of people who approved Covid-19 restrictions by vote strongly positively correlates with the percentage of people vaccinated in the population (r = 0.929, p < 0.0001). This suggests that vaccinated people are more likely to approve Covid-19 restrictions, which raises interesting questions for further research.
Impact of the COVID-19 Pandemic on Students’ Motivation in Relation to Asynchronous Anatomy Video Lectures
Authors: Cardoso-Júnior Aloisio , Faria Rosa Malena Delbone
Published: February 2022

Objectives
This study aimed to investigate medical students’ motivation in relation to asynchronous anatomy video lectures, carried out during COVID-19 remote teaching.
Methods
Repeated cross-sectional modified Instructional Materials Motivation Survey questionnaire, validated in Brazil, was applied to 255 students attending the first semester of the undergraduate medical course at the José do Rosário Vellano University, in June 2020 and November 2020. The data were analyzed considering the 95% confidence level as significant (p < 0.05).
Results
The overall score of motivation attributed by the students was moderate to high (3.7/5, 74%). The same occurred in relation to all dimensions of the instrument: Interest (3.6/5, 72%), Confidence (3.7/5, 74%), Attention (3.5/5, 70%) and Expectation (3.7/5, 74%). Cluster analysis showed that 78% (n = 168) of the students had moderate (72% of the maximum score) or high (86% of the maximum score) degrees of motivation. The influence of social isolation on the students’ emotional state did not affect the overall motivation scores (p = 0.217) or the dimensions of motivation: Interest (p = 0342); Confidence (p = 0.061); Attention (p = 0.625) and Expectation (p = 0.094).
Conclusions
The students showed high motivation for the asynchronous video lectures of human anatomy. Although the majority of students are highly affected regarding their emotional state, due to the social isolation imposed by the Covid-19 pandemic, this fact did not interfere with the motivation for video lectures, probably due to the high intrinsic motivation that students in the first year have in relation to anatomy. These findings alert to the importance of asynchronous video lectures as an adequate strategy for the teaching and learning of human anatomy.
Successive Products Approach and its Application for Binomial Numbers Extensions from the Natural to the Integer Domain
Authors: Moesia Marlo , Karam-Filho Jose , Giraldi Gilson Antônio
Published: February 2022

This work starts presenting recursive equations in the domain of sequences indexed by integers and their solutions obtained by applying the successive operations introduced in Moesia (2017). Following the original approach, the methodology is developed considering the traditional algebraic group structure. Starting from the dual interpretation of recursions, the notion of successive operations applied on sequences indexed by integers is revisited and some properties highlighted. More important, the successive operations approach is a general way to study previously extended functions from N to Z. As a demonstration of this capability, a class of binomial numbers extensions from the natural domain to the integer one is established here, allowing seeing that different pre-existing extensions of binomial numbers are, in fact, particular cases of just one general extension, developed in this work through the successive product machinery. To exemplify, binomials derived from two known factorial extensions are represented in this framework and their most known recursive expressions are studied. From this study it is also verified that by using the successive product it is possible to avoid extensive demonstrations required by standard methods, resulting in remarkably short and simple proofs.

Authors: Ibrahim Musa Alhaji , Çamur Hüseyin , Savaş Mahmut A. , S.I. Abba
Published: February 2022

Filled polymer composites are widely used for automobile, structural and aerospace components owing to their exceptional combination of high specific stiffness and strength. This study presents Taguchi-Deng optimization of tribological parameters such as load, grit size, distance and speed as well as prediction of tribological behaviours of carbon-filled and bronze-filled polytetrafluoroethylene (PTFE) composites using pin on disk configuration. A plan of experiments based on Taguchi L27 (43) orthogonal array (OA) was designed to collect data in a controlled manner. The Taguchi L27 (43) was hybridized with Deng model to produce grey relational grades (GRG) for the multiple response optimization. Analysis of variance (ANOVA) was executed to establish the parameters affecting GRG of the composites. For the prediction of the tribological behaviours of the composites namely coefficient of friction (µ) and specific wear rate (Ks), support vector regression (SVR) was coupled with novel Harris Hawks’ optimization (HHO) and swarm particle optimization (PSO) forming SVR-HHO and SVR-PSO models respectively, were employed. Prediction accuracy of the models were appraised using coefficient of determination (R2), correlation coefficient (R), root mean square error (RMSE) and mean absolute percentage error (MAPE). GRG results revealed that optimum parameters which reduced tribological behaviours were factor combination L3G1D3S3. ANOVA for GRG reveled that grit size with 68.57% ranks as the most influential parameter followed by load with 20.57%, followed by distance having a contribution of 7.78% and finally speed with least contribution of 3.38% for minimum tribological loss. Validation performed using optimum parameters revealed an enhancement of 55% in GRG. Prediction accuracy of the single model increase to 19.50% and 57.08% on the average for hybrid µ and Ks models, respectively. Furthermore, SVR-HHO model indicated the higher prediction accuracy of the tribological behaviours of filled PTFE composites as compared to SVR-PSO model. These findings concluded these metaheuristic models are promising in predicting tribological behaviours of filled PTFE composites and thus can serve as a guide in the design and development of tribological materials.

Authors: Koch Amanda Manes , Gasparetto Valdirene , Ensslin Sandra Rolim
Published: February 2022

O perfil crítico e seletivo do consumidor contemporâneo e a competição crescente representam desafios para a gestão da cadeia de suprimentos agroalimentar, o que demanda atenção à mensuração e gestão de desempenho nesse contexto. Em vista disso, este estudo objetiva analisar as características dos artigos científicos que abordam o fragmento de literatura referente à avaliação de desempenho em cadeias de suprimentos agroalimentares a fim de identificar seu estágio de evolução e oportunidades para pesquisas futuras. Para atingir o objetivo proposto, utilizou-se o instrumento de intervenção Knowledge Development Process-Constructivist (ProKnow-C). Verifica-se que a literatura atribui ênfase à mensuração do desempenho, enquanto a gestão do desempenho permanece limitada. Os Sistemas de Avaliação de Desempenho (SADs) não incorporam singularidades das cadeias investigadas, o que pode representar uma adversidade para o desempenho a longo prazo. Além disso, não há integração entre os indicadores de desempenho e suas escalas de medição de forma a permitir uma visão holística e sistêmica do desempenho, o que limita as informações fornecidas para apoio à decisão. Com os resultados obtidos, vislumbram-se oportunidades para pesquisadores e gestores, como identificar medidas de desempenho que ultrapassam o horizonte organizacional e possam ser utilizadas para avaliar o desempenho em nível interorganizacional. Além disso, considerar peculiaridades, inerentes ao setor agroalimentar e a cadeia de suprimentos observada, e interesses dos decisores ao construir um SAD representa um desafio tanto para pesquisadores quanto para gestores. Esforços também devem ser direcionados a estudos longitudinais sobre as fases do ciclo de vida do SAD e a aspectos comportamentais que afetam a integração entre os membros da cadeia e dificultam ou contribuem para a gestão de desempenho interorganizacional.

Published: February 2022

BACKGROUND

Type 2 diabetes is twice as likely to affect Hispanic people than their White counterparts. Technology and social support may be an important part of behavior change. In this study, we address gaps in diabetes care for Hispanic Spanish-speaking people with diabetes through an online peer support community (OPSC) pilot intervention using Hispanic Spanish-speaking peer facilitators with diabetes to enhance the use of continuous glucose monitoring (CGM) for diabetes management.

OBJECTIVE

This study aims to address gaps in diabetes care for Hispanic Spanish-speaking people with diabetes through an OPSC pilot intervention using Hispanic Spanish-speaking peer facilitators with diabetes to enhance the use of CGM for diabetes management.

METHODS

A mixed-methods, pre-post test design will be used in this feasibility study. A total of 50 Hispanic participants with type 2 diabetes willing to wear a continuous glucose monitor for 13 weeks will be recruited. Hispanic Spanish-speaking peer facilitators with diabetes and experience wearing a continuous glucose monitor will be employed and undergo training. Peer facilitators will help participants learn how CGM data can inform behavior changes via an OPSC. Participants will interact with the private OPSC at least three times a week. Weekly questions and prompts derived from the Association of Diabetes Care and Education Specialists, previously American Association of Diabetes Educators, and seven self-care behaviors will be delivered by peer facilitators to engage participants. Measures of feasibility and acceptability will be determined by the percentage of participants who enroll, complete the study, and use CGM (number of scans) and objective metrics from the OPSC. Efficacy potential outcomes include change in time in range of 70 to 180 mg/dL from baseline to 12 weeks, A1c, diabetes online community engagement, self-efficacy, and quality of life. Additionally, semistructured exit interviews will be conducted.

RESULTS

Funding for this project was secured in November 2018 and approved by the institutional review board in April 2019. Peer facilitator recruitment and training were undertaken in the second half of 2019, with participant recruitment and data collection conducted in January and April 2020. The study has now concluded.

CONCLUSIONS

This study will generate new evidence about the use of an OPSC for Hispanic Spanish-speaking patients with diabetes to make behavior changes incorporating feedback from CGM.

Published: February 2022

In 2017, one billion people contracted fungal infection with 11.5 million people contracted life-threatening infection and 1.5 million death per year. Orchid is a plant that grows in tropical and sub-tropical countries, the same places where fungal infection occurrence is high. On previous studies reported that orchid contains alkaloids and polyphenols such as flavonoid, and phenol acid. The review aimed to identify the orchid as a potential antifungal resource. A scoping review was used. The type of articles reviewed were original articles obtained from five electronic journal databases published within 2012-2021. Three articles reported similar result which was that orchid extract has a significant antifungal activity although the part of plant used was different, ranging from the root, to the leaf. Two articles reported a specific antifungal activity against Candida albicans while the remaining one against Trichophyton rubrum. In conclusion, the root, leaf, branch, and flower extracts of orchid is potential antifungal resources.
Au-Ru nanoparticles in catalysis, analysis from first-principles calculations
Authors: Molina Tenrreyra Uriel Omar , Mojica Molina Rodrigo Hebert , Torres Hernández Ana Elizabeth
Published: February 2022

Nobel-metal based bimetallic nanoparticles (BNPs) are composed of two different metals presenting heteroatom interactions. In these nanomaterials it is possible to tune the relative composition that allows for the modulation of electronic and catalytic properties. They are of great interest for their technological and industrial applications due to their catalytic properties which may exceed those of their monometallic analogue structures. A theoretical perspective on the electronic, stability and reactivity related properties of gold, ruthenium and Au-Ru nanoparticles is presented herein. This analysis considered the use of first-principles methods and the cluster approach to get a physical insight into the novel properties that arise from the combination of two metals in the nano and sub-nano scale. Au-Ru BNPs may present a higher catalytic efficiency than the monometallic structures due to the synergy between the metals in the CO oxidation reaction. However, the effect of Ru over the Au-based NPs on their enhanced catalytic activity is not well understood. A density functional theory (DFT) study of one Au-Ru cluster model was performed to analyze its electronic properties and to gain a better understanding in the stability of structures with various metal compositions.

Based on the computed mixing enthalpy, the Au-Ru cluster with a core-shell type morphology and a relative composition close to 1:0.75 was determined as the most stable one. Finally, a CO oxidation reaction pathway different from that determined for Au-NPs was presented for the free particle occurring in the Au-Ru interface. O2 may undergo adsorption on a Ru site through a dissociative process. The computed CO oxidation barrier height is lower than that found for the monometallic Ru clusters but is higher than that determined for Au clusters. This study will guide further research on this kind of model nanostructures in heterogeneous catalysis.
Economic Value Added: Acritical Reading
Authors: Elmadhoun Dr. Ibrahim R. I. , Murtaja Mohammed H. K.
Published: February 2022

Abstract: It is clear how important is the measure of Economic Value-Added and preference that this measure has over traditional performance measures. This measure is based on creating value for the company, and this measure is distinguished by taking into account invested capital, whether owned or borrowed. In addition, studies have shown that the measure of Economic Value Added increases the performance of the company and the performance of the management working. This measure affects the market value of the company and its use leads to maximizing the wealth of shareholders, and like all performance measures he has supporters and has critics. One of the criticisms directed against him is that he measures performance on the short level, as he cares about results, not causes, and the most important criticism directed at him is his dependence on accounting profit in the financial statements whether these statements represent the actual performance of the company or not. Keywords: Economic Value Added, Profit Indicator, Financial Management

Abstract: In wireless medium, necessity of higher frequency is expanding day by day. For higher frequency deploy system data rates should be higher. In unguided medium, as signal passes a longer distance and due to intervention of noise, there is fallacy. In phases and frequencies and we get a drifted output. In view of this, we are prompted to make a low power frequency synthesizer which would provide a lower locking time, low settling time, average value of damping factor to give a regulated frequency response at the output. The suggested design aspect is for higher frequency which is executed in IEEE 802.11 WLAN standard and OFDM technology, Bluetooth technology, high frequency processor. We have used Microwind 3.1 55nm technology and ADS as outline tool to execute design.

The spread of anti-sexual violence campaigns on social media such as the #metoo, #kitaAgni and #namabaikkampus movements raises public awareness about the issue. This can be seen in the rejection and public anger related to the news about the glorification of sex offenders who incidentally was a public figure when he was released from prison which was published in online media. Therefore, this article examines the implications of anti-sexual violence discourse on the glorification of sexual offenders in online media by using critical discourse analysis by Sara Mills which focuses on the position of subject-object and the position of readers in the news. This article shows that there is a discourse battle between the sex offenders who show resistance while the public continues to reject it simultaneously.
O PATRIMÔNIO HISTÓRICO/CULTURAL DA CIDADE DE CAMPO BOM-RS: UMA LEITURA SOBRE O URBANO E OS PATRIMÔNIOS CULTURAIS
Authors: Manfio Vanessa
Published: February 2022

A cidade de Campo Bom localizada na região metropolitana de Porto Alegre foi uma área de colonização alemã no Rio Grande do Sul e dessa herança colonial surgiram equipamentos e formas urbanas que permanecem no espaço até os dias de hoje, sendo verdadeiros patrimônios culturais. A cidade vem caminhando desde a década de 1990 para preservar os patrimônios culturais e históricos, mas encontra muitos obstáculos, entre eles a demolição de vários antigos casarões históricos e a falta de política de patrimonização. Pensando nisto, este artigo busca discutir a respeito da noção de patrimônio cultural/histórico, articulando com a necessidade de salvaguardar os patrimônios da cidade de Campo Bom, como parte essencial da memória e vida urbana. Para isto, utilizou-se o método exploratório descritivo, bem como a coleta de dados, aplicação de questionários e a revisão de literatura. Contudo, a expectativa do trabalho é contribuir com a abordagem do patrimônio cultural no espaço urbano, especialmente em Campo Bom.
Protein engineering strategies for tailoring the physical and catalytic properties of enzymes for defined industrial applications
Authors: Kumar Rakesh , Kumar Arbind , Kaur Jagdeep
Published: February 2022

Highly evolved biocatalysts that can endure harsh environmental
conditions during industrial processes are highly desirable. The
availability of suitable biocatalysts with high enzyme activity,
substrate selectivity, and stability could lower the production costs in
the pharmaceutical, chemical, and food industries, resulting in more
economical products. Naturally evolved enzymes could not be exploited in
industrial applications because of their compromised properties. Till
date, protein engineering strategies have helped us improve the desired
physical and catalytic properties of enzymes to meet their performance
needs in industrial and medical applications. Protein engineering
technologies such as directed evolution and rational redesigning are
well-suited for improving bio-catalytic properties. Each approach has
its own set of limitations, and the implementation of techniques is
contingent on the availability of prerequisite information about the
biocatalyst. Protein structure information is essential for rational
design, but no prior structural knowledge is required for directed
evolution. Furthermore, semi-rational approaches and enzyme designing
are also being used. Considering these facts, this study outlines the
various molecular techniques used to improve the physical and catalytic
properties of enzymes. It also emphasizes the magnitude of particular
strategies used to improve the properties of biocatalysts to meet the
needs of industrial processes.

‘Culture as a Verb’ and ‘Otherness’: Reflections on Conceptual Threads from Brian Street’s Early Writing
Authors: Castanheira Maria Lucia , Santos Juliana
Published: February 2022

This text re-examines the early and ongoing work of Brian Street and highlights the lasting relevance of Street’s analysis of “ethnographic novels” presented in the book The Savage in Literature: Representations of ‘primitive’ society in English fiction 1858-1920. First, it presents an overview of Street’s analysis of representations of ‘primitive society’ in “ethnographic novels”, then, it identifies two conceptual threads – ‘culture as a verb’ and ‘otherness’ –, whose roots can be found in this book, and that Street continued to develop throughout his academic career.  The paper argues that Street’s early work speaks directly to those concerned today with examining power relationships in colonial and post-colonial contexts.

Hearing Early Modern Music Through the Contemporary
Authors: Øvrebø Daniel Henry
Published: February 2022

This chapter focuses on how contemporary music practice interacts with early modern1 aesthetics. Two projects, in which Georg Philip Telemann’s solo fantasias are interspersed with contemporary techniques and repertoire, serve as case studies. Firstly, the flutist Felix Renggli commissioned new pieces from 11 contemporary Swiss composers, to be inserted in between Telemann’s 12 Fantasias for Solo Flute. Secondly, violinist Aisha Orazbayeva performed a set of Telemann’s Solo Fantasias for Violin using extended techniques pioneered by Salvatore Sciarrino in his 6 caprices. In this text I use these two different approaches as case studies for how early modern music, exemplified by Telemann, can be communicated to a modern audience without relying upon the concept of historically informed performance, but instead communicates through the operation of semiotics in performance.

Cooperation between enterprises is the basis for industrial clusters' existence and developments, while it is embedded in the enterprises' social network. Cluster organizations are one of the tools to support performance and competitiveness. The article analyses the influence of the existence of a cluster organization in the textile industry on finance performance of its member companies. For research purposes, the companies were divided into two groups. The first group consisted of companies included members of the CLUTEX Cluster which represent an organized cluster. The second group consisted of companies that do business in the same geographic region as the organized cluster, but are not its members. The aim of the research was to verify the statement that enterprises that create the core of the cluster organization achieved higher financial performance than all other non-member enterprises in the same geographic region doing business in the same industry. The Wilcoxon-Mann-Whitney W test and Kolmogorov-Smirnov test were used to determine the difference between the research samples. The technical efficiency of companies in all these groups was examined using DEA Window Analysis for the period of 2009–2019.

Subsurface Evapotranspiration Irrigation System Design in System of Rice Intensification (SRI) Salibu Paddy Cultivation
Authors: Agustina Hilda , Setiawan Budi Indra , Sugiyanta  , Solahudin Mohamad , Dewi Vita Ayu Kusuma
Published: February 2022

The System of Rice Intensification (SRI), a water-saving paddy cultivation system, has been implemented in Indonesia. The application of SRI  can increase water productivity. The Salibu method applied to paddy cultivation can save seeds, costs, labour and increase the planting index of paddy. However, when used in other areas, the yield is reduced by up to 50 per cent from the first harvest. A combination of cultivation and water management is needed to save water and increase paddy production. The method used in this research is experimental research. The design of the irrigation system was made according to the technical design, then tested for automatic water management. The design was tested with the SRI Salibu method. The data are climate data, water level, water discharge, and water content. The climate data used are temperature and solar radiation to determine potential evapotranspiration. The results of observations of water depth, the volume of water in the system, the water content in the media, water entering the system (rain infiltration, irrigation discharge), and water leaving the system (runoff, discharge) are entered into the water balance equation (water balance). The plant coefficient value is included in the water balance equation as a plant coefficient factor multiplied by the potential evapotranspiration value. Then the plant coefficient value for each observation is optimized by reducing the error value to get the coefficient value for SRI Salibu. The results showed that the appropriate evapotranspiration irrigation system for SRI Salibu paddy cultivation is the fifth irrigation system design. The fifth irrigation system design can produce 4.7 tons/ha of paddy (SRI method) and produce SRI Salibu paddy yields of 8 tons/ha. The irrigation water for SRI paddy cultivation is 1738 litres, and the water production is 1.2 kg/m3.

Decreasing Phosphorus Fertility to Reduce Sweetpotato Root Growth During Container-grown Transplant Production
Authors: Rouse L. , Beasley J. , LaBonte D. , Kuehny J.
Published: February 2022

Sweetpotato [Ipomoea batatas (L.) Lam.], grown as an edible ornamental, is propagated in home gardens using locally purchased transplants. However, vigorous growth of sweetpotato limits the period of transplant salability due to root confinement. The objective of the experiment was to evaluate reductions in phosphorus (P) fertility to slow transplant root growth and extend the period of salability. Cuttings were planted into containers and fertilized at 0, 5 (0.0007), 10 (0.0012), 15 (0.0020), 20 (0.0024), and 31 mg P.L −1 (0.0040 oz P.gal−1) using a modified Hoagland solution. All transplants fertilized at ≥5 mg P.L −1 increased in shoot length, color, and biomass during the first four weeks after planting (WAP) but declined thereafter. Transplant roots fertilized at ≥5 mg P.L −1 (0.0007 oz P.gal−1) increased in total length, surface area, and volume throughout the six-week production cycle. However, P fertility <15 mg.L -1 (0.0020 oz P.gal−1) resulted in narrower storage roots with lower root volumes. Reducing P fertility from 31 (0.0040 oz P.gal−1) to 5 mg L −1 (0.0007 oz P.gal−1) did not sufficiently slow transplant rooting to prevent roots from reaching container walls to extend the period of salability.

Index words: root length, root diameter, root biomass, and root architecture.

O mundo empresarial é repleto de situações complexas e inovadoras. Diante disso, muitos empresários buscam meios para se adequar às diversas normas impostas pela regulamentação civil e comercial. Nesse contexto nasceu a necessidade de criação de uma empresa, que orientasse e desse sequência aos objetivos da firma, como forma de proteção dos bens conquistados no decorrer de décadas. Para tanto, observando as necessidades do mercado e vislumbrando uma maior proteção jurídica surgiram empresas denominadas de Holdings, que possuem como desígnio a promoção do melhor caminho e direcionamento dos bens constituídos, por empresários e empresas. Essas, por sua vez, possuem como objetivo principal propiciar, de forma legal, a proteção dos bens, por intermédio de um planejamento sucessório, organizado, com a garantia administrativa e a continuidade dos negócios, salvaguardando o patrimônio delas. O objetivo da presente pesquisa é refletir e propor alternativas para a criação de holdings, de acordo com a necessidade individual de cada empresa, através de um planejamento sucessório e patrimonial, a fim de que se possa garantir a continuidade e os direitos de seus herdeiros. A esse estudo se utilizou o método dedutivo/descritivo, tendo em vista a crescente preocupação de muitas empresas manter a continuidade dos objetivos a que se propuseram, bem como às pessoas físicas de proteger e resguardar os bens patrimoniais de futuras discussões intermináveis e desgastantes. Para tanto, se utilizou a técnica de pesquisa bibliográfica e documental, para a compreensão da importância da criação de uma holding familiar, numa empresa.

Bully activities at school have a long-term detrimental effect. Though the types and manifests of this damaging behavior are studied, there is a paucity of evidence on its social determinants. Aim and Objective: This study explored the socio-demographic determinants of school-bullying in a central India district. Methods: Cross-sectional data were compiled over one year from 480 participants by simple random method from urban and rural schools. The bully Prevalence Questionnaire (BPQ) and socio-demographic information questionnaire were used. Questionnaires in English and Hindi language were commissioned to cater to the participants’ need. SPSS Vs. 21 was used for data analysis at P ≤ 0.05. Results: The urban vs. rural divide was noticable (ꭓ2; p -0.033). Boys involvement was dominant (66.2% vs, 30.4% and ꭓ2; p -0.00). Father’s occupation and family income were the important social determinants (ꭓ2 value p -0.00, ANOVA p - 0.02, and 0.05). Victimization per se was noticed more among girls as compared to boy’s (r .310** vs. .144*). Children of unskilled workers were more often a party to school bullying (r .317**). Father and mother’s educational levels were strong players in deciding students’ prosocial skills (ANOVA p -0.014 and 0.00). Participants’ self-esteem score was influenced by family income (ANOVA p -0.00). Conclusion: Involvement of boys at high number was a matter of concern. The skewed number in favour of children from unskilled working families necessitates the attention of social reformists and policymakers. Improved education of parents is also vital in curbing this social evil.

Estudio observacional sobre la llegada y el estado actual de las poblaciones del cangrejo decápodo pantropical Cronius ruber (Lamarck, 1818) en la isla de Tenerife. Se trata de una especie de la familia Portunidae, cuyos primeros registros publicados en Canarias se producen en el año 2017, siendo citada por primera vez en el litoral de Tenerife en el año 2018; aunque por la información recabada para este trabajo, los primeros registros de la presencia de esta especie en Tenerife se remontan al año 2008. Se trata de una especie neocolonizadora a tener en cuenta por su potencialidad invasora en los archipiélagos de Madeira y Canarias. Su aparición en las Islas ha sido relacionada principalmente con el intenso transporte marítimo entre Canarias y África occidental; sin embargo, no podemos descartar una expansión natural de sus poblaciones relacionada con el calentamiento reciente de las aguas de Canarias, propicias para el establecimiento de especies tropicales. Con este estudio pretendemos además definir el nicho ecológico ocupado por C. ruber y valorar de manera cualitativa el grado de competencia con otras especies de crustáceos decápodos nativos presentes en el litoral de Canarias.

The sea urchin Diadema antillarum is an herbivore that plays an important ecological role in controlling benthic community structure in Caribbean reefs. After the mass mortality documented between 1982-1983, their populations were reduced by 94-99% triggering a phase shift from coral to macroalgae-dominated benthic communities across the Caribbean. Almost 4 decades after its regional collapse, it is not clear weather D. antillarum populations are recovering, thus local surveys are valuable to track the fate of this herbivore. This study aims to determine the population structure of this sea urchin in a shallow reef located southeast of the Dominican Republic. We conducted a visual survey in three haphazardly selected sites of the reef studying a total surface of 90 m2 in which test size and D. antillarum densities were measured. Overall, the mean density of D. antillarum was 1.77 ± 1.07 ind/ m2 (Mean ± SD) with an average test size of 67.3 ± 22.7 mm (Mean ± SD) a median of 70 mm and a mode of 80 mm. Test diameter had a platykurtic distribution (kurtosis = 2.53) slightly skewed to the left (skewness = -0.1). This information is valuable to establish a local baseline to follow up the population dynamics of this key species.

Sürdürülebilirlik tartışmalarının yoğun yaşandığı günümüz dünyasında, tartışmalara konu olan bir alan da yeşil büyümedir. Sürdürülebilir bir çevrenin teşviki noktasında yeşil büyüme önemli bir strateji olarak görülmektedir. Yeşil büyümenin gerçekleşmesini zorlaştıran unsurların başında karbondioksit salınımları gelmektedir. Askeri faaliyetlerin de yoğun şekilde karbondioksit salınımına neden olduğu gerçeği söz konusudur. Son dönemlerde geliştirilen askeri teknolojilerin ise çevre dostu olduğu ve kirliliği azaltmaya yönelik hedefler belirlediği de konuya ilişkin çalışmalarda dile getirilmektedir. Bu ilişkilerin ampirik olarak incelenmesi ve detaylarının ortaya koyulması önem arz etmektedir. Bu çalışmada, askeri harcamalar ile yeşil büyüme arasındaki ilişkinin ortaya koyulması amaçlanmıştır. Bu doğrultuda 1995-2017 dönemi verileri ışığında, LM bootstrap panel eşbütünleşme, Emirmahmutoğlu ve Köse panel nedensellik testleri ve AMG uzun dönem tahmin edicileri kullanılmıştır. Ulaşılan ampirik bulgular panelin geneli ve ülkeler özelinde değerlendirilmiştir. Elde edilen bulgular, gelişmişlik seviyesi yüksek olan ülkelerde, askeri harcamaların yeşil büyüme üzerinde pozitif etkiye sahip olduğunu ve nispeten daha az gelişmiş ülkelerde ise bu etkinin negatif olduğunu ortaya koymaktadır. Bulgular, özellikle gelişmekte olan ülkelerin yeşil büyümeye yönelik politik uygulamalara önem vermesi gerektiğini göstermektedir.

Objetivo: Descrever a inserção curricular e analisar a satisfação dos discentes em medicina sobre o ensino de gestão baseado em simulação, em particular no manejo de maus tratos a criança. O ensino de gestão, geralmente ocorre de forma teórica, e no ambiente real muitas vezes não é possível ou homogêneo abordar os todos os casos necessários. Métodos: Estudo exploratório de abordagem quantitativa em questionário aplicado a 57 discentes do oitavo semestre de medicina. Os dados foram analisados com estatísticas descritivas e o estudo foi aprovado por Comitê de Ética em Pesquisa. Resultados: Todos os discentes consideraram estas simulações fundamentais para a formação e a sugerem como temática obrigatória no curso. A percepção sobre o foco da atividade teve grande variabilidade, tanto no foco percebido como no desejado pelos estudantes, uma vez que a assistência técnica é supervalorizada, mesmo em cenários onde a condução assistencial e administrativa possa significar o bem-estar do paciente. Conclusão: Não há relatos publicados sobre implementação de simulação na área de gestão na graduação, logo o estudo evidencia sua importância para que possa ser vivenciado e compartilhado emoções e condutas em ambiente controlado para atuação médica de qualidade.
