Schematic Structure of Manifesto Launch Speeches of Three Political Parties
Authors: Afful Joseph Benjamin Archibald , Gyasi Rexford Boateng
Published: January 2021

A key pre-election spoken genre in several modern democracies is unarguably the manifesto launch speech. Yet, it has surprisingly received either very little or no scholarly attention. Consequently, from a rhetorical perspective, this study examined the schematic structure of three keynote speeches delivered by presidential aspirants of three leading political parties in Ghana – New Patriotic Party (NPP), National Democratic Congress (NDC), and the Convention People’s Party (CPP) – to launch their political parties’ manifestos in 2016. The three speeches delivered by the presidential candidates of the three parties constituted the data set for the study. Applying the popular Swalesean rhetorical move analysis, originally meant for the academic setting, the study identified the use of a nine-move pattern as the schematic structure for the genre across the three speeches, with four ambiguous moves. These findings of the study have implication for the standardizing of the schematic structure of manifesto launch speeches worldwide and, thus, contributes to the scholarship on the political manifesto genre, political communication as well as further research on manifesto launch speeches in other democracies around the world.
Contribution of English aural vocabulary size levels to L2 listening comprehension
Authors: Du Guohui , Hasim Zuwati , Chew Fong Peng
Published: January 2021

This study investigated the relationship between English aural vocabulary size and L2 listening comprehension among 288 Chinese tertiary EFL learners who had mastered the first 1,000-word frequency level and were at the intermediate level of language proficiency. The Listening Vocabulary Levels Test and College English Test Band 4 were employed to measure participants’ aural vocabulary size and L2 listening comprehension proficiency, respectively. Aural vocabulary size was found to be moderately correlated with L2 listening comprehension proficiency (r = 0.38, p < 0.01). A step-wise regression analysis showed that the second 1,000-word frequency level could explain 12% of the variance in L2 listening comprehension proficiency, and academic words could add an additional 4% predictive capacity to the regression model. A hierarchical regression analysis revealed that the most frequent 2,000-word families and academic words could predict 14.5% of the change in L2 listening comprehension proficiency for the relatively low L2 proficiency group. However, aural vocabulary size had little impact on L2 listening comprehension proficiency for the relatively high L2 proficiency group. Findings suggest that high-frequency and academic words significantly contribute to the prediction of L2 listening comprehension proficiency, but the predictive power of aural vocabulary size decreases with increased language proficiency.
How to extend Elo: a Bayesian perspective
Authors: Ingram Martin
Published: January 2021

The Elo rating system, originally designed for rating chess players, has since become a popular way to estimate competitors’ time-varying skills in many sports. Though the self-correcting Elo algorithm is simple and intuitive, it lacks a probabilistic justification which can make it hard to extend. In this paper, we present a simple connection between approximate Bayesian posterior mode estimation and Elo. We provide a novel justification of the approximations made by linking Elo to steady-state Kalman filtering. Our second key contribution is to observe that the derivation suggests a straightforward procedure for extending Elo. We use the procedure to derive versions of Elo incorporating margins of victory, correlated skills across different playing surfaces, and differing skills by tournament level in tennis. Combining all these extensions results in the most complete version of Elo presented for the sport yet. We evaluate the derived models on two seasons of men’s professional tennis matches (2018 and 2019). The best-performing model was able to predict matches with higher accuracy than both Elo and Glicko (65.8% compared to 63.7 and 63.5%, respectively) and a higher mean log-likelihood (−0.615 compared to −0.632 and −0.633, respectively), demonstrating the proposed model’s ability to improve predictions.
Correlations of serum beta 2-microglobulin level with disease activity and renal involvement in patients with systemic lupus erythematosus
Authors: Liu Bingxin , Lu Feng , Lin Jing , Zou Hongmei
Published: January 2021

Objectives

To determine correlations of serum beta 2-microglobulin (β2-MG) level with disease activity and renal involvement in patients with systemic lupus erythematosus (SLE).

Methods

Two hundred eligible SLE patients were assigned into remission and active stage groups according to SLE disease activity index (SLEDAI) scores. They were also assigned into kidney damage and no kidney damage groups. Serum β2-MG, Scr, ALB, BUN, anti-dsDNA, complements C3, C4 and 24-h urinary total protein (UTP) were detected. Estimated glomerular filtration rate (eGFR) was calculated. Correlations of β2-MG level with SLEDAI score and eGFR were subjected to Spearman analysis. Affecting factors were explored by logistic multivariate regression analysis, and predictive values of β2-MG level for SLE, disease activity and renal damage were assessed by ROC curves.

Results

β2-MG, Scr, ALB, C3, C4, anti-dsDNA and UTP levels, eGFR and SLEDAI score were different between patients with different disease activities, and, except for eGFR, also between patients with different renal damage degrees (p<0.05). Serum β2-MG, Scr, ALB, C3, C4, anti-dsDNA, UTP, eGFR and SLEDAI score were independent factors for disease activity (p<0.05), and β2-MG, ALB, C3, UTP, eGFR and SLEDAI score were factors affecting renal damage (p<0.05). β2-MG level was correlated positively with SLEDAI score (r=0.877, p=0.000) and negatively with eGFR (r=−0.873, p=0.000). This level was highly valuable for predicting SLE, disease activity and renal damage.

Conclusions

Serum β2-MG levels in SLE patients are correlated positively with disease activity and negatively with renal involvement, being highly sensitive and specific for predicting SLE, disease activity and eGFR.

Published: January 2021

In this article, a modified variational iteration method along with Laplace transformation is used for obtaining the solution of fractional-order nonlinear convection–diffusion equations (CDEs). The proposed technique is applied for the first time to solve fractional-order nonlinear CDEs and attain a series-form solution with the quick rate of convergence. Tabular and graphical representations are presented to confirm the reliability of the suggested technique. The solutions are calculated for fractional as well as for integer orders of the problems. The solution graphs of the solutions at various fractional derivatives are plotted. The accuracy is measured in terms of absolute error. The higher degree of accuracy is observed from the table and figures. It is further investigated that fractional solutions have the convergence behavior toward the solution at integer order. The applicability of the present technique is verified by illustrative examples. The simple and effective procedure of the current technique supports its implementation to solve other nonlinear fractional problems in different areas of applied science.
Prediction of capillary suction in porous media based on micro-CT technology and B–C model
Authors: Li Min , Yu Hemiao , Du Hongpu
Published: January 2021

Moisture variation in porous media depends mainly on the pore characteristics. This article used the micro-computed tomography (micro-CT) (a non-destructive imaging technique to generate a three-dimensional virtual model) and the Brooks–Corey model to deduce the moisture migration in sand. Relationship between capillary rise height and time (h–t) was achieved by numerical simulation in the capillary suction process, where the parameters fractal dimension, porosity, and air–water interfacial area were obtained by the micro-CT scanning. Meanwhile, experiments of capillary rise in sand column were performed using four different sizes washed sand, and the capillary heights at different times were recorded. Results show that the capillary suction is decided by the aperture size and phase morphology simultaneously, and particle size has obvious effect on capillarity, and the wetting front lowers with the increase in grain size and the decrease in rising rate. Parameters air entry pressure and pore-size distribution index obtained by micro-CT scanning technology and empirical formula are accurate. Method of combing micro-CT images and Brooks–Corey model can predict well the capillary suction of porous media. It is also proved that the capillary suction is decided by the aperture size and phase morphology simultaneously.

Published: January 2021

In this article, the Sinh–Gordon function method and sub-equation method are used to construct traveling wave solutions of modified equal width equation. Thanks to the proposed methods, trigonometric soliton, dark soliton, and complex hyperbolic solutions of the considered equation are obtained. Common aspects, differences, advantages, and disadvantages of both analytical methods are discussed. It has been shown that the traveling wave solutions produced by both analytical methods with different base equations have different properties. 2D, 3D, and contour graphics are offered for solutions obtained by choosing appropriate values of the parameters. To evaluate the feasibility and efficacy of these techniques, a nonlinear evolution equation was investigated, and with the help of symbolic calculation, these methods have been shown to be a powerful, reliable, and effective mathematical tool for the solution of nonlinear partial differential equations.
Biological nanoscale fluorescent probes: From structure and performance to bioimaging
Authors: Wan Jiafeng , Zhang Xiaoyuan , Zhang Kai , Su Zhiqiang
Published: January 2021

In recent years, nanomaterials have attracted lots of attention from researchers due to their unique properties. Nanometer fluorescent materials, such as organic dyes, semiconductor quantum dots (QDs), metal nano-clusters (MNCs), carbon dots (CDs), etc., are widely used in biological imaging due to their high sensitivity, short response time, and excellent accuracy. Nanometer fluorescent probes can not only perform in vitro imaging of organisms but also achieve in vivo imaging. This provides medical staff with great convenience in cancer treatment. Combined with contemporary medical methods, faster and more effective treatment of cancer is achievable. This article explains the response mechanism of three-nanometer fluorescent probes: the principle of induced electron transfer (PET), the principle of fluorescence resonance energy transfer (FRET), and the principle of intramolecular charge transfer (ICT), showing the semiconductor QDs, precious MNCs, and CDs. The excellent performance of the three kinds of nano fluorescent materials in biological imaging is highlighted, and the application of these three kinds of nano fluorescent probes in targeted biological imaging is also introduced. Nanometer fluorescent materials will show their significance in the field of biomedicine.
Evaluating the relative contribution of data sources in a Bayesian analysis with the application of estimating the size of hard to reach populations
Authors: Parsons Jacob , Niu Xiaoyue , Bao Le
Published: January 2021

Objectives

When using multiple data sources in an analysis, it is important to understand the influence of each data source on the analysis and the consistency of the data sources with each other and the model. We suggest the use of a retrospective value of information framework in order to address such concerns.

Methods

Value of information methods can be computationally difficult. We illustrate the use of computational methods that allow these methods to be applied even in relatively complicated settings. In illustrating the proposed methods, we focus on an application in estimating the size of hard to reach populations. Specifically, we consider estimating the number of injection drug users in Ukraine by combining all available data sources spanning over half a decade and numerous sub-national areas in the Ukraine. This application is of interest to public health researchers as this hard to reach population that plays a large role in the spread of HIV.

Results and conclusions

We apply a Bayesian hierarchical model and evaluate the contribution of each data source in terms of absolute influence, expected influence, and level of surprise. Finally we apply value of information methods to inform suggestions on future data collection.
FFA and OFA Encode Distinct Types of Face Identity Information
Authors: Tsantani Maria , Kriegeskorte Nikolaus , Storrs Katherine , Williams Adrian Lloyd , McGettigan Carolyn , Garrido Lúcia
Published: January 2021

Faces of different people elicit distinct fMRI patterns in several face-selective regions of the human brain. Here we used representational similarity analysis to investigate what type of identity-distinguishing information is encoded in three face-selective regions: fusiform face area (FFA), occipital face area (OFA), and posterior superior temporal sulcus (pSTS). In a sample of 30 human participants (22 females, 8 males), we used fMRI to measure brain activity patterns elicited by naturalistic videos of famous face identities, and compared their representational distances in each region with models of the differences between identities. We built diverse candidate models, ranging from low-level image-computable properties (pixel-wise, GIST, and Gabor-Jet dissimilarities), through higher-level image-computable descriptions (OpenFace deep neural network, trained to cluster faces by identity), to complex human-rated properties (perceived similarity, social traits, and gender). We found marked differences in the information represented by the FFA and OFA. Dissimilarities between face identities in FFA were accounted for by differences in perceived similarity, Social Traits, Gender, and by the OpenFace network. In contrast, representational distances in OFA were mainly driven by differences in low-level image-based properties (pixel-wise and Gabor-Jet dissimilarities). Our results suggest that, although FFA and OFA can both discriminate between identities, the FFA representation is further removed from the image, encoding higher-level perceptual and social face information.

SIGNIFICANCE STATEMENTRecent studies using fMRI have shown that several face-responsive brain regions can distinguish between different face identities. It is however unclear whether these different face-responsive regions distinguish between identities in similar or different ways. We used representational similarity analysis to investigate the computations within three brain regions in response to naturalistically varying videos of face identities. Our results revealed that two regions, the fusiform face area and the occipital face area, encode distinct identity information about faces. Although identity can be decoded from both regions, identity representations in fusiform face area primarily contained information about social traits, gender, and high-level visual features, whereas occipital face area primarily represented lower-level image features.
Virus and school: reflections about the factors that have exacerbated the consequences of the health emergency in Italy
Authors:   Università degli Studi di Ferrara, La Vecchia Loredana
Published: January 2021

Italy was the first European country which has been affected by the fast spread of SARS-Cov-2, leading to a general lockdown that started on March 9, 2020, only two weeks after the diagnosis of the Italian patient zero. Such lockdown concerned also the school, that is, the social institution which suffered —and keeps suffering— the most the negative effects of the national restrictions whether because of the lack of precise indications regarding the didactics after the suspension of in-class activities or because of the deficiencies and criticalities that it has been facing since ages. It was only in April when teachers could eventually resort to e-learning; though, due to the lack of both methodological indications and adequate study plans, each school acted autonomously and the best they could. In most cases, it was the teachers’ initiative and individual efforts that led to a successful didactics. As a matter of fact, teachers tried any kind of strategy to keep in touch actively with their students, as testified through the technique of the focus group. Although, in disagreement with the message of hope spread during the lockdown, not everything has gone well; that is, the virus has highlighted a chronical situation of fragility and vulnerability, whose negative consequences and effects seem to persist also in the future. This essay aims at analysing what happened during the first Italian lockdown framing the impact of the COVID-19 pandemic on a sociocultural dimension. For this purpose, I will take into account the main contextual factors that have contributed to worsen —from the didactic and teaching perspective— the consequences of the spread of the virus.

Young gay, bisexual, and other MSM (men who have sex with men) and transgender women in the United States (US) who are living with HIV, and particularly those who are Latino, have low rates of viral suppression. The weCare intervention uses social media to increase HIV care engagement. Method: We used community-based participatory research to develop the intervention as well as theory-based social media messages tailored to each participant’s unique context. We analyzed elements and characteristics of weCare, messages sent by the Cyber Health Educator (CHE), and lessons learned to meet the needs of Latino participants living with HIV. Results: We identified 6 core elements, 5 key characteristics, effective social media messages used in implementation, and 8 important lessons regarding relationships between the CHE and HIV clinics, the CHE and participants, and participants and the health system. Conclusions: Social media offers a promising platform to retain young Latino gay bisexual and other MSM and transgender women living with HIV in care and achieve viral suppression.
MANAGEMENT OF ENDOCRINE DISEASE: Glucocorticoid-induced adrenal insufficiency: replace while we wait for evidence?
Authors: Laugesen Kristina , Broersen Leonie H A , Hansen Simon Bøggild , Dekkers Olaf M , Sørensen Henrik Toft , Jorgensen Jens Otto L
Published: January 2021

Glucocorticoids are, besides non-steroidal anti-inflammatory drugs, the most widely used anti-inflammatory medications. Prevalence studies indicate substantial use of both systemic and locally acting agents. A recognised adverse effect of glucocorticoid treatment is adrenal insufficiency, which is highly prevalent based on biochemical testing, but its clinical implications are poorly understood. Current evidence, including randomised trials and observational studies, indicates substantial variation among patients in both risk and course of glucocorticoid-induced adrenal insufficiency, but both are currently unpredictable. Oral and intra-articular formulations, as well as long-term and high-dose treatments, carry the highest risk of glucocorticoid-induced adrenal insufficiency defined by biochemical tests. However, no route of administration, treatment duration, or dose can be considered without risk. More research is needed to estimate the risk and temporal pattern of glucocorticoid-induced adrenal insufficiency, to investigate its clinical implications, and to identify predictors of risk and prognosis. Randomized trials are required to evaluate whether hydrocortisone replacement therapy mitigates risk and symptoms of glucocorticoid-induced adrenal insufficiency in patients discontinuing glucocorticoid treatment. This review aims to provide an overview of the available evidence, pointing to knowledge gaps and unmet needs.

Epílogo Un texto necesario… pero insuficiente. Estudios sobre medio ambiente y sostenibilidad: una mirada desde Colombia
Authors: Mauricio Hernández Pérez
Published: January 2021

Cuando los editores me hicieron extensiva la invitación para redactar y participar en este texto mediante un epílogo no lo pensé dos veces y acepté gustosamente la invitación. Después de reflexionar con atención caí en la cuenta que dentro de mi experiencia en el mundo editorial he tenido diferentes papeles: autor, co-autor, compilador y editor y que dentro de estos espacios he redactado introducciones, presentaciones y he articulado algunos textos. Sin embargo, y en lo que llevo hasta el momento de mi experiencia, nunca he redactado un epílogo. De manera tal que de antemano he de ofrecer las disculpas del caso a usted, estimado lector, en segundo lugar a los autores y por supuesto a los editores quienes tomaron el riesgo de invitarme en el “cierre” de la obra toda vez que las expectativas puestas en las siguientes líneas pueden no llegar a satisfacer lo esperado y en lo absoluto hacer justicia al texto en su contenido. Afortunadamente la calidad del mismo hace que se defienda por sí solo. En definitiva, lo importante ha quedado escrito en las páginas precedentes por lo que no entraré a señalar asuntos relacionados con las temáticas, conceptos e ideas expuestos sino que presentaré unas apreciaciones muy generales sobre lo que el texto suscita.

Published: January 2021

OBJECTIVES:

To develop predictive models for death or neurodevelopmental impairment (NDI) after neonatal hypoxic-ischemic encephalopathy (HIE) from data readily available at the time of NICU admission (“early”) or discharge (“cumulative”).

METHODS:

In this retrospective cohort analysis, we used data from the Children’s Hospitals Neonatal Consortium Database (2010–2016). Infants born at ≥35 weeks’ gestation and treated with therapeutic hypothermia for HIE at 11 participating sites were included; infants without Bayley Scales of Infant Development scores documented after 11 months of age were excluded. The primary outcome was death or NDI. Multivariable models were generated with 80% of the cohort; validation was performed in the remaining 20%.

RESULTS:

The primary outcome occurred in 242 of 486 infants; 180 died and 62 infants surviving to follow-up had NDI. HIE severity, epinephrine administration in the delivery room, and respiratory support and fraction of inspired oxygen of 0.21 at admission were significant in the early model. Severity of EEG findings was combined with HIE severity for the cumulative model, and additional significant variables included the use of steroids for blood pressure management and significant brain injury on MRI. Discovery models revealed areas under the curve of 0.852 for the early model and of 0.861 for the cumulative model, and both models performed well in the validation cohort (goodness-of-fit χ2: P = .24 and .06, respectively).

CONCLUSIONS:

Establishing reliable predictive models will enable clinicians to more accurately evaluate HIE severity and may allow for more targeted early therapies for those at highest risk of death or NDI.
Sudden Cardiac Death Risk Stratification and Prevention in Chagas Disease: A Non-systematic Review of the Literature
Authors: Keegan Roberto , Yeung Cynthia , Baranchuk Adrian
Published: January 2021

Chagas disease is an important public health problem in Latin America. However, migration and globalisation have resulted in the increased presence of Chagas disease worldwide. Sudden cardiac death is the leading cause of death in people with Chagas disease, most often due to ventricular fibrillation. Although more common in patients with documented ventricular arrhythmias, sudden cardiac death can also be the first manifestation of Chagas disease in patients with no previous symptoms or known heart failure. Major predictors of sudden cardiac death include cardiac arrest, sustained and non-sustained ventricular tachycardia, left ventricular dysfunction, syncope and bradycardia. The authors review the predictors and risk stratification score developed by Rassi et al. for death in Chagas heart disease. They also discuss the evidence for anti-arrhythmic drugs, catheter ablation, ICDs and pacemakers for the prevention of sudden cardiac death in these patients. Given the widespread global burden, understanding the risk stratification and prevention of sudden cardiac death in Chagas disease is of timely concern.
Decisões sobre o prazo de endividamento de empresas brasileiras de capital aberto – um modelo ajustado com base em teorias de imperfeições do mercado e ambiente macroeconômico (2000-2011)
Authors: De Moura Fábio Viana
Published: January 2021

O principal objetivo deste trabalho foi o de identificar fatores que influenciam o prazo do endividamento de empresas brasileiras não financeiras de capital aberto. Com base em teorias de imperfeições do mercado, testou hipóteses sobre até que ponto as oportunidades de investimento, o tamanho e a qualidade da empresa, as despesas tributárias, a regulamentação do setor, a alavancagem financeira e, adicionalmente, a conjuntura macroeconômica afetariam a decisão das empresas observadas pela escolha de uma maior proporção de endividamento de curto prazo. Após ajustes na base de dados, foi observada uma amostra de 386 empresas, no período compreendido entre 2000 e 2011. O total das observações analisadas foi de 2385, organizadas em um painel não balanceado. Com o auxílio do software R-project, foram estimados e testados modelos de regressão múltipla: OLS pooling, de efeitos fixos e de efeitos aleatórios. Os testes indicaram um melhor ajuste para o modelo de efeitos fixos, que apresenta estimativas de coeficientes de regressão teoricamente consistentes com as predições das teorias que fundamentam o trabalho. O modelo testado mostra que hipóteses construídas com base em teorias de imperfeições de mercado e ambiente macroeconômico são relevantes para explicar o prazo de endividamento de companhias brasileiras.

Published: January 2021

O presente estudo foi desenvolvido visando identificar a gestão práticada nas usinas de cana-de-açúcar e relacionando-as ao conceito de Responsabilidade Socioambiental Empresarial (RSAE). Utilizou-se como base teórica o tripé da sustentabilidade, Triple Bottom Line, que se funda no estudo dos aspectos econômicos, sociais e ambientais. Pesquisa de natureza descritiva do tipo quali-quantitativa. Adotado como metodologia de abordagem o estudo de casos múltiplos realizado em um universo de treze usinas em operação na região escolhida (PE). Para coleta de dados utilizou-se entrevistas semi-diretivas e questionários em escala Likert, envolvendo gestores das usinas, dirigentes de sindicatos, associações e agentes de órgãos de fiscalização ambiental. Foram utilizadas para interpretação dos dados, técnicas de análise de conteúdo, estatística descritiva (teste de hipóteses) e análise multivariada de dados (análise de cluster). Observou-se que a gestão praticada pelas usinas converge para a existência de dois grupos: um formado por empresas que desempenham com responsabilidade socioambiental e outro formado por usinas menos adeptas às práticas sustentáveis. A constatação que se pode extrair permite concluir que a RSAE até existe na prática das usinas do setor, mas não advém da expectativa em obter vantagem competitiva e sim, como estratégia de sobrevivência.

Molecular biologists rely very heavily on computer science algorithms as research tools. The process of finding the longest common subsequence of two DNA sequences has a wide range of applications in modern bioinformatics. Genetics databases can hold enormous amounts of raw data,
for example the human genome consists of approximately three billion DNA base pairs. The processing of this gigantic volume of data necessitates the use of extremely efficient string algorithms. This paper introduces a space and time effective technique for retrieving the longest common subsequence
of DNA sequences.
A Comparative Study of Different Techniques for Prime Testing in Implementation of RSA
Authors: Banerjee Kumarjit , Mandal Satyendra Nath , Das Sanjoy Kumar
Published: January 2021

The RSA cryptosystem, invented by Ron Rivest, Adi Shamir and Len Adleman was first publicized in the August 1977 issue of Scientific American. The security level of this algorithm very much depends on two large prime numbers. The large primes have been taken by BigInteger in Java.
An algorithm has been proposed to calculate the exact square root of the given number. Three methods have been used to check whether a given number is prime or not. In trial division approach, a number has to be divided from 2 to the half the square root of the number. The number will be not
prime if it gives any factor in trial division. A prime number can be represented by 6n±1 but all numbers which are of the form 6n±1 may not be prime. A set of linear equations like 30k+1, 30k+7, 30k+11, 30k+13, 30k+17, 30k+19, 30k+23 and 30k+29 also have been used to produce
pseudo primes. In this paper, an effort has been made to implement all three methods in implementation of RSA algorithm with large integers. A comparison has been made based on their time complexity and number of pseudo primes. It has been observed that the set of linear equations, have given
better results compared to other methods.

Published: January 2021

Backstepping is a realistic nonlinear control design algorithm based on Lyapunov design approach; therefore, it automatically ensures the convergence of the regulated variable to zero. In this paper, it has been proposed for robust synchronization of Duffing chaotic systems. Integral
action is being used to enhance the control action of the controller in steady state against the disturbances. The salient feature of the design is that the derived control doesn’t contain any derivative terms; consequently it simplifies the controller realization. The effectiveness
of the proposed controller has been demonstrated in simulation studies. The performance of the controller has been evaluated not only based on its synchronizing ability but also the disturbance rejection ability of the controller has been verified.

ABSTRACT Objective: To analyze the sociodemographic and epidemiological profile of suicide in the indigenous and non-indigenous population and the spatiality of the event. Method: Epidemiological, descriptive research, carried out with data from the Mortality Information System. Suicide mortality rates were calculated for the 144 municipalities in Pará and linked to the geographic location values of the municipalities; subsequently, thematic maps were built using the QGIS 3.10.3 software. The association between variables was measured by the G test. Results: 1,387 suicide records were studied, and the mortality rate among indigenous people was low in comparison to non-indigenous people, reaching 0.1/100 thousand inhabitants and 17.5/100 thousand inhabitants, respectively. Conclusion: Suicide is heterogeneously distributed in the territory, with greater vulnerability of the indigenous people, which demands different policies considering their cultural diversity.

Resumo A partir do mapeamento de ações desenvolvidas por grupos feministas para a segurança digital, chamados de "cuidados digitais", analisamos as suas estratégias, que surgem em resposta às opacidades e injustiças algorítmicas, à pouca diversidade nos espaços tecnológicos e ao crescimento das violências de gênero nos ambientes digitais. Neste texto vamos discutir um aspecto deste hacktivismo (autodenominado de hackfeminista), o dos cuidados digitais, a partir da perspectiva feminista da ética do cuidado (Gilligan, 2013; Hirata e Debert, 2016), confrontando-a com os princípios da ética hacker (Levy, 1994; Himanen, 2001).

Resumo Objetivo Analisar a frequência do uso de preservativos segundo fatores de vulnerabilidade para infecções sexualmente transmissíveis em comunidades quilombolas de Sergipe, Brasil. Métodos Estudo transversal descritivo, realizado entre 2016 e 2017. Utilizou-se questionário estruturado, com questões sociodemográficas e comportamentais; foram realizados testes rápidos de HIV e sífilis. Comparações entre variáveis categóricas foram realizadas pelo teste exato de Fisher. Resultados Entre os 367 indivíduos de 14 comunidades, a maioria apresentava baixa escolaridade (72,8%), encontrava-se sem trabalho (59,7%) e possuía parceiro sexual fixo (90,7%). Falta de acesso a insumos e informações de prevenção compuseram a vulnerabilidade programática dos indivíduos. Houve maior proporção de uso inconsistente do preservativo com parceiro fixo (90,1%), em indivíduos que relataram falta de acesso à informação (p=0,001) e uso inconsistente com parceiro eventual (p<0,001). Conclusão A frequência de uso do preservativo com parceiro fixo foi significativamente proporcional ao uso com parceiro eventual e ao acesso a informação preventiva.
Effect of hyperbranched polycarboxylic acid superplasticiser on the properties of cement paste

Published: January 2021

Comb-like polycarboxylate is a superplasticiser possessing a high water reducing rate and excellent molecular design, and has been widely used in the concrete industry. Most research studies have adjusted the effect of the superplasticiser by improving the groups on the superplasticiser molecular chain, but few studies have been carried out that change the structure of the comb molecular chain. AB2 monomer was prepared by the Michael addition reaction of diethanolamine and methyl acrylate, and hyperbranched polymer was prepared with trihydroxypropane as the core. In this paper, an advanced hyperbranched polycarboxylate, which was modified by a hyperbranched polyamine-ester, was designed as a superplasticiser. The hyperbranched polycarboxylic acid superplasticiser has the advantage of improving the rheological properties of cement slurry and the strength of mortar test blocks, compared with the traditional polycarboxylate superplasticiser; this is attributed to the hyperbranched polymers that provide hydroxyl groups and enhance the molecular spatial structure.

An investigation was carried out to improve the seismic performance of concrete columns reinforced with high-strength steel bars and subsequently retrofitted with vertical and horizontal carbon-fibre-reinforced polymer (CFRP) strips. Seven columns were constructed and tested under constant axial and cyclic lateral loading. The results showed that attaching CFRP vertical strips in or over grooves outperformed conventional externally bonded reinforcement, as evidenced by greater energy dissipation and strength. Furthermore, the use of corner strip–battens for the horizontal CFRP strips was found to outperform conventional wrapping, as evidenced by greater ductility and energy dissipation. Confining stresses were also more uniformly distributed and strip rupture shifted from the edges to the mid-sides of the section.
