Digital Health Literacy
Authors: Vaz de Almeida Cristina
Published: February 2021

The pandemic has shown the importance of health organizations adapting rapidly to teleconsultation services, investing in e-health with quality criteria and monitoring outcomes. Through a literature review and gathering research already carried out on e-health communication and with practical examples, it is verified that, if the requirements of proximity, quality, and interpersonal relationship are met, better health results can be obtained. When communication is established in health via mobile phone, with image, sound, voice, text, it is thus possible to work the memory and health instructions of patients and obtain better health outcomes. These strategies must be personalized and adapted to the patient's age and context.
Emerging Trends in M-Commerce Consumer Behavior
Authors: Ettis Saïd Aboubaker , El Abidine Afef Ben Zine
Published: February 2021

By 2021, the volume of global transactions conducted by m-commerce is expected to increase. However, despite the rapid growth in the use of mobile devices, m-commerce still faces several constraints, and its integration in the consumers' everyday behavior is still less than expected in many countries. The work has a two-fold general objective: on the one hand, one wishes to describe the mobile commerce concept, and on the other hand, it is to review the relevant literature on mobile consumer behavior. This paper describes the concept of mobile commerce (m-commerce), makes the difference between e-commerce and m-commerce, and highlights its benefits and constraints. Then it reviews the relevant literature on m-consumer behavior in the stage of initial adoption and continuous use. Finally, it proposes future avenues of research in the form of research agenda. Crucially, this research urges future researchers to examine the perceived value, design, aesthetics, and experiential aspects of m-commerce and their outcomes in terms of attitude, satisfaction, loyalty, and behavioral intention.

Authors: Kaneko Tomoko , Yoshioka Nobukazu
Published: February 2021

As the complexity of computer systems increases, assuring safety and security is significant. The authors aim to construct a new development methodology CC-Case that can assure the demands of complex systems, including IoT and AI, using safety and security technologies in an integrated manner. As a central framework of CC-Case, this manuscript shows requirements extraction by STAMP/STPA extension to safety and security (STAMP S & S) and assurance using GSN divided into a logical model and a concrete model. STAMP S & S makes it possible to model requirements based on system theory and extract more comprehensive safety and security requirements in a single model diagram. Besides, the GSN defines the overall picture of the assurance and verifies and validates the hazards and threats extracted by STAMP S & S. This paper presents the procedures of CC-Case with STAMP, GSN, and show examples of level 3 autonomous driving.
A Goal-Oriented Approach to Requirements Development and Quantitative Security Assurance
Authors: Zhou Zhengshu , Zhi Qiang , Liang Zilong , Morisaki Shuji
Published: February 2021

When deciding and evaluating system security strategies, there is a trade-off relationship between security assuring effect and constraint condition, which has been revealed by many qualitative security assurance methods. However, the existing methods cannot be used to make quantitative analysis on security assurance and constraint conditions to support project managers and system engineers to decide system development strategies. Therefore, a quantitative method which can consider both security strategies and constraints is necessary. This paper proposes a semi-automatic, quantitative system security assurance approach for developing security requirement and security assurance cases by extending the traditional GSN (goal structuring notation). Next, two greedy algorithms for quantitative system security assurance are implemented and evaluated. In addition, a case study and an experiment are carried out to verify the effectiveness and efficiency of the proposed approach and the proposed algorithms.
NT-ODP Theoretical Model Extension
Authors: El Hamzaoui Mustapha , Bensalah Faycal
Published: February 2021

Inside organizations (enterprise, administration, etc.), operation/management and decision-making activities use dependently different types of information. The organization-information interactions are generally divided into five main operations (storage, manipulation, security, communication, and management) and employ IS (information system) and/or ICTs (information and communication technologies) that represent the major uses of new technologies (NT) inside organizations. Technically, the modernization of information exploitation inside organizations, through NT, is still an interesting research topic where questions mainly concern the concepts such as information, data, IS, and ICTs themselves (definitions, mutual relations, locations, etc.). This paper presents an extension of the basic theoretical model NT-ODP which illustrated the possible relations which could occur inside organizations, between new technologies (NT) tools and the organizations digital patrimony (ODP). By modifying the way in which the fundamental aspects of the basic model are applied, this new extension aims to illustrate the accurate manner in which to organize the different departments of an organization in order to be able to profit effectively from the organization digital patrimony.
Strategy for Reducing Delays and Energy Consumption in Cloudlet-Based Mobile Cloud Computing
Authors: Alakbarov Rashid
Published: February 2021

In the paper, the problem of using cloudlet-based mobile cloud computing to solve the issues (resource deficiency and limited energy) that require large computing and memory resources on mobile devices has been studied. Energy-saving of mobile devices, resource limitations in mobile devices, and elimination of network delays are analyzed. It is shown that the solution of mobile users' tasks in the cloud leads to the increased battery life of mobile devices and reduces network delays, which is shown by mathematical calculations. The article considers the balanced distribution of the tasks in the cloudlet network. The paper also deals with the selection of cloudlets according to user requirements. The cases for which a cloud application can be loaded by the user were evaluated and a model was proposed using the possible values that determine the importance of cloudlets (user proximity, high reliability, etc.).
A TERRITORIALIZAÇÃO DO MOVIMENTO DOS TRABALHADORES RURAIS SEM TERRA - MST NA MICRORREGIÃO GEOGRÁFICA DE CAMPO MOURÃO, PARANÁ - BRASIL
Authors: Viana de Andrade Aurea Andrade , Serra Elpídio
Published: February 2021

O novo modelo de produção agrícola que se instalou no Brasil, entre as décadas de 1960 e 1970, efetivou-se de modo contraditório, uma vez que as políticas públicas de desenvolvimento rural corroboram com as desigualdades sociais no campo com a desterritorialização de milhares de trabalhadores rurais, especialmente no estado do Paraná. Tal processo contribuiu para organização de novos territórios e de novas territorialidades. Igualmente, nos últimos anos, na região de Campo Mourão, surgiram novos territórios no espaço rural e, dentre eles, os de trabalhadores rurais sem-terra: uma parte organizada na forma de assentamentos, implantados pelo poder municipal em parceria com o Instituto Nacional de Colonização e Reforma Agrária - INCRA, outros na forma de acampamentos que se transformam, por meio da luta, em assentamentos. Para melhor compreensão desse movimento de des-re-territorilização dos trabalhadores rurais sem-terra, abordamos, na pesquisa, o processo da territorialização do Movimento dos Trabalhadores Rurais Sem Terra – MST na Microrregião Geográfica de Campo Mourão. A pesquisa teve um caráter teórico e empírico com entrevistas e depoimentos dos trabalhadores rurais sem-terra dos assentamentos e dos acampamentos Irmã Dorothy e Nossa Senhora do Carmo, localizados no município de Barbosa Ferraz. Esses movimentos são formas de poder e de resistência à ordem estabelecida na sociedade capitalista.
FORÇAS EM LUTA: BACHELARD E NIETZSCHE NA GEOGRAFIA DE ÉRIC DARDEL
Authors: Davim David Emanuel Madeira , Marandola Junior Eduardo José
Published: February 2021

Desde a publicação, em 2011, da tradução de O Homem e a Terra: natureza da realidade geográfica, escrita pelo geógrafo francês Éric Dardel, o livro recebeu uma rápida difusão na comunidade geográfica. Uma das mais excitantes questões abertas para investigação é a multiplicidade de influências filosóficas que compõe a geografia dardeliana. O argumento defendido neste texto é que sua geografia fenomenológico-existencial, reconhecidamente de inspiração heideggeriana, também sofreu fortes influências da fenomenologia da imaginação de Gaston Bachelard. Além disso, sustenta-se que o princípio das “forças em luta”, o qual caracteriza o dinamismo da realidade geográfica de Dardel, advém de noções fundamentais da filosofia de Friedrich W. Nietzsche, via Bachelard. No esforço interpretativo expresso neste trabalho, o encontro entre Dardel e Nietzsche se estabeleceu, indiretamente, via os sentidos de terra e de vontade de potência. O objetivo deste artigo é perseguir essas pistas e nexos, buscando enriquecer as leituras contemporâneas e as aberturas oferecidas pela geografia dardeliana.

Authors: Silva Araujo Amarildo , Sieben Airton
Published: February 2021

O artigo aborda a comunidade de Apinagés localizada no município de São João do Araguaia (PA), ante a futura desterritorialização pela comunicação da Usina Hidroelétrica (UHE) Marabá no período de 2010 a 2017. O objetivo principal foi à compreensão de sua percepção por causa das incertezas que se desenharam no imaginário no contexto da futura desterritorialização e (des) construção da identidade pela notícia da construção da UHE, o posicionamento do Estado, Centrais Elétricas do Norte do Brasil S/A (ELETRONORTE) e construtora Camargo & Corrêa. A pesquisa é quali-quantitativa e optou pelas orientações filosóficas da dialética e fenomenologia. Os conceitos de território, territorialidade e identidade contribuíram para uma visão interdisciplinar das características tradicionais no modo de vida dos apinagesenses e revela uma cultura baseada na relação com rio Tocantins e ameaçada pela hidrelétrica em contexto social, econômico e cultural. Em síntese almeja-se evidenciar a relação conflituosa estabelecida entre os atingidos por barragens, o Estado e Consórcio construtor, responsável pela materialização no território de empreendimentos que altera os ciclos naturais e o modo de vida tradicional.

Numerical Analysis of Solidification Behavior during Laser Welding Nickel-Based Single-Crystal Superalloy Part I: Crystallography-Dependent Solid Aluminum Distribution
Authors: Gao Zhi Guo
Published: February 2021

The thermal metallurgical modeling of alloying aluminum redistribution was further developed through couple of heat transfer model, dendrite selection model, multicomponent dendrtie grwoth model and nonequilibrium solidification model during three-dimensional nickel-based single-crystal superalloy weld pool solidification over a wide range of welding conditions (laser power, welding speed and welding configuration) to facilitate understanding of solidification cracking phenomena. It is indicated that the welding configuration plays more important role than heat input in aluminum redistribution. The bimodal distribution of solid aluminum concentration along the solid/liquid interface is crystallographically symmetrical about the weld pool centerline for (001) and [100] welding configuration, while the distribution of solid aluminum concentration along the solid/liquid interface is crystallographically asymmetrical throughout the weld pool for (001) and [110] welding configuration. The size of vulnerable [100] dendrite growth region is beneficially suppressed in favor of epitaxial [001] dendrite growth region through optimum low heat input (low laser power and high welding speed) to facilitate single-crystal dendrite growth for successful crack-free weld at the expense of shallow weld pool geometry. The overall aluminum concentration in (001) and [100] welding configuration is significantly smaller than that of (001) and [110] welding configuration regardless of heat input. Severe aluminum enrichment is confined to [100] dendrite growth region where is more susceptible to solidification cracking. Heat input and welding configuration are optimized in order to minimize the solidification cracking susceptibility and improve microstructure stability. The relationship between welding conditions and alloying aluminum redistribution are established for solidification cracking susceptibility evaluation. The higher heat input is used, the more aluminum enrichment is monotonically incurred by diffusion with considerable increase of metallurgical driving forces for morphology instability and microstructure anomalies to deteriorate weldability and vice versa. The mechanism of asymmetrical solidification cracking because of crystallography-dependent alloying redistribution is proposed. The theoretical predictions agree well with the experiment results. Moreover, the useful modeling is also applicable to other single-crystal superalloys with similar metallurgical properties during laser welding or laser cladding.
Investigation of Using Multi-Hydroxyl Ionic Liquid Polymer as Catalyst to Produce Propylene Carbonate
Authors: Horng Richard S. , Hung Wei Cheng , Kuo Ju Wei
Published: February 2021

Ionic liquid with a single hydroxyl group, 1-(2-hydroxyl-ethyl)-3-methylimidazolium bromide (HEMIMB), was prepared. It was found that HEMIMB could be an efficient catalyst for CO2 cycloaddition to propylene oxide to produce propylene carbonate (PC). An ionic liquid polymer with multi-hydroxyl groups poly(1-2-hydroxyl-ethyl)-3-vinylimidazolium bromide (PHEVIMB) was also prepared. In this study, both catalytic reaction performances of HEMIMB and PHEVIMB were investigated. Results showed that product separation and catalyst recycles in the process of PHEVIMB catalytic reaction system was much more efficient with a yield of 55.5%, even after three consecutive catalyst reuses. Meanwhile, the separation was less time-efficient for homogeneous catalytic system of HEMIMB molecules with a single hydroxyl group despite of a yield of 92.4%. When it comes to practical industrial process design, the single component with multifunctional ionic liquid polymer, as catalyst, may be considered effective and friendly process.
Numerical Analysis of Microstructure Development during Laser Welding Nickel-Based Single-Crystal Superalloy Part II: Multicomponent Dendrite Growth
Authors: Gao Zhi Guo
Published: February 2021

A thermal metallurgical coupling model was further developed for multicomponent dendrite growth of primary γ gamma phase during laser welding nickel-based single-crystal superalloys. It is indicated that welding configuration has a predominant role on the overall dendrite trunk spacing than heat input throughout the weld pool, and modifies the dendrite growth kinetics. The dendrite trunk spacing in (001) and [100] welding configuration is finer than that of in (001) and [110] welding configuration. In (001) and [100] welding configuration, the bimodal distribution of dendrite trunk spacing is symmetrical about weld pool centerline, the dendrite trunk spacing in [100] growth region near the weld pool center is coarser than [010], [0ī0] and [001] dendrite growth regions. In (001) and [110] welding configuration, the distribution of dendrite trunk spacing is crystallographically asymmetrical, and the dendrite trunk spacing in [100] growth region is severely coarser than that of [010] and [001] dendrite growth regions. (001) and [110] welding configuration is of particular interest, because dendrite trunk spacing decreases in [100] dendrite growth region and dendrite trunk spacing increases in [010] dendrite growth region from the maximum weld pool width to the end due to crystallography-dependent growth kinetics. Moreover, strict control of low heat input (low laser power and high welding speed) beneficially promotes fine dendrite trunk spacing and reduces the size of dendrite growth regions. High heat input (high laser power and low welding speed) monotonically coarsens dendrite trunk spacing. The dendrite trunk spacing is refined and [100] dendrite growth is suppressed by the optimum low heat input and (001) and [100] welding configuration to improve weldability. An alternative mechanism of solidification cracking because of asymmetrical dendrite trunk growth is proposed. The useful results facilitate understanding of single-crystal superalloys microstructure development and solidification cracking phenomena. The theoretical predictions agree well with the experiment results. Moreover, the model is also applicable to other single-crystal superalloys with similar metallurgical properties by feasible laser welding or laser cladding.
Computational Approches for Ballistic Impact Response of Stainless Steel 304
Authors: Mostafa A.
Published: February 2021

The present study introduces a numerical procedure to estimate the impact resistance of stainless steel 304 (SS 304) commonly used in producing security screens through calculation of the effective ballistic limit velocity (V50). Non-linear finite element (FE) analysis using ABAQUS FE software was performed to simulate the material response with wide variety of thicknesses under various impact scenarios. Three different techniques were employed to determine V50, including: simulation of SS 304 using material parameters obtained from coupons testings and impact residual velocity and energy based on FE analysis. The material plasticity and damage initiation and evolution under dynamic loading conditions were simulated using Johnson-Cook model, while Lambert-Jonas model was utilized in predicting the residual impact velocity and energy using robust data regression system. Very good correlation within the investigated methodologies was observed along with obvious proportional between V50and coupons’ thickness. The significance of the outcome of this investigation is the developing of feasible and economical approach to evaluate the impact resistance of SS 304 which will significantly contribute to the development of superior security screens.

Published: February 2021

This article describes an optimization of dressing parameters to improve the wheel life in surface grinding of hardened SKD 11 steel by using the Taguchi method. Dressing parameters including dressing feed rate, coarse dressing depth, coarse dressing times, fine dressing depth, fine dressing times, and non-feeding dressing were investigated to determine their influence on the wheel life. The DOE method developed by G. Taguchi was selected to design the experiments. An analysis of the signal-to-noise (S/N) response and ANOVA were conducted to obtain the optimal values of dressing parameters for maximizing the wheel life. In the results section, the coarse dressing times and the coarse dressing depth are determined to be the most influential factors which give a statistically significant effect on wheel life. Also, a predictive value of the average wheel life is given with a 3.6% deviation from the verification experiment.
Nursing Interventions to Reduce Stress in Families of Critical Care Patients: An Integrative Review
Authors: Lebel Valérie , Charette Sylvie
Published: February 2021

Background

Having a family member admitted to an intensive care unit is a stressful experience that may lead to psychological symptoms including depression, anxiety, and posttraumatic stress disorder.

Objective

To better understand the phenomenon of stress experienced by families of intensive care unit patients and identify nursing interventions that may help reduce it.

Methods

An integrative literature review was performed to identify principal stressors for families of patients receiving care in neonatal, pediatric, and adult intensive care units and recommended nursing interventions.

Results

The principal stressors in the 3 types of intensive care units were change in parental role or family dynamics, appearance and behavior of the patient, the care setting, and communication with the health care staff. Nursing interventions should focus on valuing the role of family members in patient care, improving communication, and providing accurate information.

Clinical Relevance

Family members of intensive care patients will benefit from nursing interventions that adequately acknowledge and address the stress they experience.

Conclusion

Nurses play a crucial role in helping to reduce the stress experienced by family members of intensive care unit patients.
Beyond the Basics: A Sampling of Puzzling Dysrhythmias
Authors: Townsend Terri , Nahlawi Ghaith
Published: February 2021

Most basic dysrhythmia instruction concentrates on the fundamentals of cardiac rhythms and the criteria that make one dysrhythmia different from another. Over the past 2 decades, advances in treatment of acute coronary syndromes have made once-common dysrhythmias very rare. This article provides an overview of a few uncommon dysrhythmias (wide-QRS tachycardia, advanced atrioventricular block, sinoatrial exit block, and atrial fibrillation with complete heart block) that may be encountered when caring for patients with cardiac disorders.

Authors: Brown Kristen M. , Mudd Shawna S. , Perretta Julianne S. , Dodson Adam , Hunt Elizabeth A. , McMillan Kristen Nelson
Published: February 2021

Background

Simulation is increasingly used to identify latent threats to patient safety, such as delays in recognition and management of time-sensitive conditions. The Rapid Cycle Deliberate Practice teaching method may facilitate “nano” (brief) in situ simulation training in a critical care setting to improve multidisciplinary team performance of time-sensitive clinical tasks.

Objective

To determine whether nano–in situ simulation training with Rapid Cycle Deliberate Practice can improve pediatric intensive care unit team proficiency in identifying and managing postoperative shock in a pediatric cardiac patient.

Methods

A quality improvement educational project was conducted involving nano–in situ simulation sessions in a combined pediatric and pediatric cardiac intensive care unit. The Rapid Cycle Deliberate Practice method was used with an expert-driven checklist for 30-minute simulation scenarios.

Results

A total of 23 critical care providers participated. The proportion of time-sensitive tasks completed within 5 minutes increased significantly from before to after training (52% [13 of 25] vs 100% [25 of 25]; P ≤ .001). Using a 5-point Likert scale, with higher scores indicating higher levels, the participants reported high degrees of performance confidence (mean, 4.42; SD, 0.20) and satisfaction with the simulation experience (mean, 4.96; SD, 0.12).

Conclusion

The Rapid Cycle Deliberate Practice method was used to facilitate nano–in situ simulation training and identify areas requiring additional education to improve patient safety. In situ simulation can educate providers in a cost-effective and timely manner.
Systems Approaches to Unravel T Cell Function and Therapeutic Potential in Autoimmune Disease
Authors: Salinas Victor H. , Stüve Olaf
Published: February 2021

Producing Ag-specific immune responses constrained to target tissues or cells that can be engaged or disengaged at will is predicated on understanding the network of genes governing immune cell function, defining the rules underlying Ag specificity, and synthesizing the tools to engineer them. The successes and limitations of chimeric Ag receptor (CAR) T cells emphasize this goal, and advances in high-throughput sequencing, large-scale genomic screens, single-cell profiling, and genetic modification are providing the necessary data to bring it to fruition—including a broader application into the treatment of autoimmune diseases. In this review, we delve into the implementation of these developments, survey the relevant works, and propose a framework for generating the next generation of synthetic T cells informed by the principles learned from these systems approaches.

Vohwinkel Syndrome, also known as Keratoderma Hereditarium Mutilans, is an extremely rare dominant autosomal keratosis. It typically presents with “starfish” keratoses on the knuckles, palmoplantar keratoderma (PPK), hearing impairment and mutilating digital constriction bands (pseudoainhum) that cause strangulation, often leading to autoamputation of the affected digit. Both medical and surgical treatment haven’t shown to date consistent results, in the treatment of pseudoainhum. In this study we present the case of a woman with Vohwinkel syndrome who showed constriction bands causing ischemic changes of the 5th digit of the right hand for which she was treated with surgery. We also present a review of the literature for the management of this disease.
Birds of Metauro river: a great ornithological diversity in a small Italian urbanizing biotope, requiring greater protection
Authors: Bai Simone Ottorino , Pantalone Marco
Published: February 2021

This work is a qualitative analysis of the ornithological diversity in the area of Metauro river estuary and its lower course (Fano, Marche, Italy), a set of little wetlands of great birdlife conservation interest, defined in an urbanized context. Data collection took place through standardized censuses and ornithological observations in situ, from September 2010 to September 2020, integrated with an accurate bibliographic research on historical data. A total of 253 species have been recorded in the site; 59 (23.32%) breed in the area, whereas 50 (19.76%) species are vagrant and 72 species (28.57%) are included in the Annex I of the Birds Directive (79/409/CEE). We determined the following indices: NP/P (ratio between the number of species non Passerines and Passerines) = 1.94, O.V.I. (Ornithological Value Index) = 20.80. The data relating to species of conservation interest and vagrant are reported in detail, in order to provide useful information for interventions for greater protection of the area. The high ornithological diversity and species richness highlighted in this study confirms the regional and national importance of the Metauro river estuary and the wetlands in its lower course, providing further data and giving support to more incisive conservation interventions, made necessary by the ever-increasing impact of disturbance and low naturalistic protection, that threatens the existence of the various and small biotopes of this important naturalistic area.
Mitigating the risk of alcohol use among university students
Authors: Erinfolami Adebayo Rasheed , Olagunju Andrew Toyin , Akije Adedeji Olasunkanmi , Ogunsemi Olawale
Published: February 2021

Background:

The rising prevalence of alcohol use among youths in low resource settings is a major public health issue of concern, especially as alcohol use remains a leading contributor to deaths and disability globally. This study aimed to evaluate the effects of screening and brief intervention (SBI) on alcohol use risk among university students.

Methods:

In this quasi-experimental study, a total of 636 students were screened for alcohol use risk with the World Health Organization Alcohol, Smoking, and Substance Involvement Screening Test (WHO-ASSIST) version 3.1. All participants with moderate and high risk of alcohol use were administered brief intervention (BI) delivered by trained students at baseline, 1 month, and 3 months, with a final assessment in 6 months. Longitudinal data on their alcohol use risk were analyzed.

Results:

The mean age (standard deviation) of the participants was 21.13 (3.05) years and 44.5% were female. The prevalence of the current alcohol use based on the WHO-ASSIST was 49.2% (n = 315). Following three sessions of BI, the repeated measures ANOVA indicated that the WHO-ASSIST mean score for high-risk alcohol users (n = 44) fell from 33.23 (3.82) at baseline to 18.3 (9.84) at 6th month. This difference was statistically significant. Similarly, the mean score for moderate alcohol users fell from 19.62 (2.97) at baseline to 11.31 (5.52) at 6 months. The difference was statistically significant. There were significant group-level differences in the risk score over the study period, for the low risk, moderate risk, and high-risk users at the end of the study.

Conclusion:

Screening and BI showed significant benefits on alcohol use risk. Our findings suggest SBI as a feasible and effective intervention for mitigating the risk of alcohol use among young students in resource-restricted settings. Further research using a robust sample to reflect differences in setting and student characteristics is warranted.
Characterizations of Hardy spaces for Fourier integral operators
Authors: Rozendaal Jan
Published: February 2021

We prove several characterizations of the Hardy spaces for Fourier integral operators

\mathcal{H}^{p}_{\mathrm{FIO}}(\mathbb{R}^n)

, for

1 < p < \infty

. First we characterize

\mathcal{H}^{p}_{\mathrm{FIO}}(\mathbb{R}^n)

in terms of

L^{p}(\mathbb{R}^n)

-norms of parabolic frequency localizations. As a corollary, any characterization of

L^{p}(\mathbb{R}^n)

yields a corresponding version for

\mathcal{H}^{p}_{\mathrm{FIO}}(\mathbb{R}^n)

. In particular, we obtain a maximal function characterization and a characterization in terms of vertical square functions.
Vortex dynamics for 2D Euler flows with unbounded vorticity
Authors: Ceci Stefano , Seis Christian
Published: February 2021

It is well known that the dynamics of vortices in an ideal incompressible two-dimensional fluid contained in a bounded not necessarily simply connected smooth domain is described by the Kirchhoff–Routh point vortex system. In this paper, we revisit the classical problem of how well solutions to the Euler equations approximate these vortex dynamics, and extend previous rigorous results to the case where the vorticity field is unbounded. More precisely, we establish estimates for the 2-Wasserstein distance between the vorticity and the empirical measure associated with the point vortex dynamics. In particular, we derive an estimate on the order of weak convergence of the Euler solutions to the solutions of the point vortex system.

The WHO recommends improving access to water as part of a comprehensive strategy for elimination of trachoma as a public health problem; however, this recommendation is not based on evidence from randomized trials. In a region of Ethiopia with hyperendemic trachoma, seven communities were randomized to a hand-dug well (HDW) and seven communities to no intervention to determine the impact of HDWs on the community prevalence of ocular chlamydia infection (primary prespecified outcome). All communities continued to receive government hygiene and sanitation services and outreach. Participants were not masked, given the nature of the intervention, but laboratory personnel were masked to treatment allocation. Hand-dug wells were successfully built in six of the seven communities; five of these wells were still functional at the conclusion of the trial. At the end of the trial, an average of 74% of households reported traveling < 30 minutes to collect water in the HDW arm, compared with 45% in the control arm, and the daily volume of water used for hygiene was similar (e.g., mean of 0.7 L per person in each arm). The pseudo-median prevalence of ocular chlamydia among 0- to 5-year old children at the 24-month visit was 23% in the HDW group and 13% in the control group (P > 0.99). This small cluster-randomized trial provided no evidence to suggest that simply constructing HDWs, in the absence of other hygiene promotion activities, is effective for reducing transmission of ocular chlamydia.

Published: February 2021

Growing evidence suggests current water, sanitation, and hygiene interventions do not improve domestic hygiene sufficiently to improve infant health, nor consider the age-specific behaviors which increase infection risk. A household playspace (HPS) is described as one critical intervention to reduce direct fecal–oral transmission within formative growth periods. This article details both the design and development (materials and methods), and testing (results) of a HPS for rural Ethiopian households. Design and testing followed a multi-sectoral, multistep participatory process. This included a focus group discussion (FGD), two user-centered and participatory design workshops in the United Kingdom and Ethiopia, discussions with local manufacturers, and a Trials by Improved Practices (TIPs) leading to a final prototype design. Testing included the FGD and TIPs study and a subsequent randomized controlled feasibility trial in Ethiopian households. This multi-sectoral, multistage development process demonstrated a HPS is an acceptable and feasible intervention in these low-income, rural subsistence Ethiopian households. A HPS may help reduce fecal–oral transmission and infection—particularly in settings where free-range domestic livestock present an increased risk. With the need to better tailor interventions to improve infant health, this article also provides a framework for future groups developing similar material inputs and highlights the value of participatory design in this field.

Following vaccination with the live attenuated, recombinant vesicular stomatitis virus Indiana serotype Ebola virus (rVSV-EBOV) vaccine, persons may exhibit a transient vaccine-associated viremia. To investigate the potential for Old World sand flies to transmit this vaccine following feeding on a viremic person, we fed laboratory-reared Phlebotomus papatasi an artificial blood meal containing 7.2 log10 plaque-forming units of rVSV-EBOV. Replication or dissemination was not detected in the body or legs of any P. papatasi collected at seven (n = 75) or 15 (n = 75) days post-feed. These results indicate a low potential for rVSV-EBOV to replicate and disseminate in P. papatasi, a species whose geographic distribution ranges from Morocco to southwest Asia and as far north as southern Europe.

The point-of-care urine based strip test for the detection of circulating cathodic antigen (POC-CCA) in schistosome infections is a frequently used tool for diagnosis and mapping of Schistosoma mansoni in school-aged children. Because of its ease of use, the test is increasingly applied to adults and preschool-aged children (PSAC), but its performance has not been specifically evaluated in these target groups. Recent observations have raised concerns about possible reduced specificity, in particular in pregnant women (PW) and PSAC. We thus explored specificity of the POC-CCA urine strip test (Rapid Medical Diagnostics, Pretoria, South Africa) in a non-endemic, nonexposed population of 47 healthy nonpregnant adults (NPAs), 52 PW, and 58 PSAC. A total of 157 urines were tested with POC-CCA, of which five (10.6%) NPAs, 17 (32.7%) PW, and 27 (46.5%) PSAC were positive. The highest scores were found in the youngest babies, with an infant of 9 months being the oldest positive case. On measuring pH, it appeared that all POC-CCA strongly positive urines were acidic (pH range 5–5.5), whereas addition of pH-neutral buffer to a subsample reversed the false positivity. We conclude that the POC-CCA test has reduced specificity in PW and infants younger than 9 months, but that the false positivity might be eliminated by modifications in the buffers used in the test.
Enhancing Community Participation in Ecotourism through a Local Community Participation Improvement Model
Authors: Gumede Thembinkosi , Nzama Antonia
Published: February 2021

This study aimed to explore the model that can be used to improve local community participation in ecotourism development processes. The study was conducted at the communities adjoining the Oribi Gorge Nature Reserve in KwaZulu-Natal, South Africa. A mixed methods design was adopted by the study during collection and analysis of data. A total of 384 respondents were sampled through convenience sampling technique. Questionnaires were used to collect data through face-to-face surveys. The study found that local communities had not been actively participating in ecotourism development processes, especially those undertaken within the rural setting as a result of different socio-economic factors including lacking necessary skills. This study asserts that this gap could be mitigated through implementation of local community participation improvement model (LCPIM) based on its potential for influencing enactment and/or amendment of policies on ecotourism development
Transformation of Villas to Mosques Social Impact of Islamization On The Government Center of Java In The Late 20th Century
Authors: Muh Saerozi
Published: February 2021

Islamization of Java becomes an actual topic of religious social research because the phenomena not only relate to religious discourse but also other aspects. This research focuses on the Islamization of the government center of Salatiga Central Java. The aims of this study are: to find the academic answer to why Islamization occurred in the government center of Salatiga in Central Java, to find out the Islamization process underway, to describe the dominant factors affecting Islamization, and to describe the impact of Islamization on religious life around the central government. The benefit of this research is to contribute the theories of Islamization of Government center of Java in the late of 20th century. This study is a descriptive research and causality analysis.  The events were limited to those of 1985 to 2018. The data were sourced from the archives, inscription, news, interviews, and literature. The results of the study found that the Islamization of the Salatiga government center was carried out because the infrastructure was still European patterned. The actualization of Muslim religiosity was not well supported by this infrastructure. The symbol of Islamization is the transformation of the villa on the west of the city square into a mosque. The Islamization was successful because of the symbiotic factors between political parties, rulers, scholars, Islamic universities, and religious organizations. There was no significant impact yet on the improvement of spiritual and social lives around the government center. This study enriches theories about the symbiotic relations of religions, politics, and social changes in Java in the late 20th century.

Narrar historias con estructuras que incluyen lenguajes adaptables al mensaje, es la forma natural que tenemos de transmitir información. La alfabetización en salud hace referencia a la utilización de información por parte de las personas, para la toma de decisiones relacionadas a la salud individual y colectiva. Las instituciones dedicadas a esto suelen presentar limitantes narrativas, por lo que conocer aspectos para el análisis y propuesta de iniciativas alternativas, contribuye al fortalecimiento del proceso de alfabetización y sus involucrados. A través del método etnográfico y de investigación narrativa, este trabajo reflexiona acerca de estos aspectos clave con base en una campaña de uso de condón divulgada en Facebook, con la finalidad de aportar bases teórico-metodológicas para la alfabetización en salud.
