Listening to Voices from African American Communities in the Southern States about COVID-19 Vaccine Information and Communication: A Qualitative Study
Authors: Zhang Ran , Qiao Shan , McKeever Brooke W. , Olatosi Bankole , Li Xiaoming
Published: June 2022

The high uptake of COVID-19 vaccines is one of the most promising measures to control the pandemic. However, some African American (AA) communities exhibit vaccination hesitancy due to mis- or disinformation. It is important to understand the challenges in accessing reliable COVID-19 vaccine information and to develop feasible health communication interventions based on voices from AA communities. We conducted 2 focus group discussions (FGDs) among 18 community stakeholders recruited from 3 counties in South Carolina on 8 October and 29 October 2021. The FGDs were conducted online via Zoom meetings. The FGD data were managed and thematically analyzed using NVivo 12. Participants worked primarily in colleges, churches, and health agencies. We found that the challenges of accessing reliable vaccine information in AA communities primarily included structural barriers, information barriers, and a lack of trust. Community stakeholders recommended recruiting trusted messengers, using social events to reach target populations, and conducting health communication campaigns through open dialogue among stakeholders. Health communication interventions directed at COVID-19 vaccine uptake should be grounded in ongoing community engagement, trust-building activities, and transparent communication about vaccine development. Tailoring health communication interventions to different groups may help reduce misinformation spread and thus promote vaccination in AA communities in the southern states.

Published: June 2022

The genus Corynebacterium, composed of Gram-positive diphtheroid rod-shaped bacteria, induces severe diseases, such as Corynebacterium-associated hyperkeratosis and pseudotuberculosis, in immunodeficient mice. We isolated and identified a total of 165 strains of Corynebacterium species from experimental mice in Korean laboratories, diagnosed using several methods. When identified based on molecular methods, namely, 16S rRNA and rpoB gene sequence analysis, the main Corynebacterium species isolated in Korean laboratory mice were C. mastitidis (44.8%, n = 74), C. bovis (25.5%, n = 42), C. lowii (21.2%, n = 35), and C. amycolatum (8.5%, n = 14). Diagnoses were also performed using matrix-assisted laser desorption/ionization–time of flight mass spectrometry (MALDI-TOF MS) and biochemical methods. MALDI-TOF MS yielded results that were 77.9% identical to the molecular identification results, whereas biochemical methods showed only 15.5% identical to molecular identification, partly owing to difficulties in distinguishing among C. mastitidis strains. Collectively, our findings indicate that molecular biological methods are better suited for detecting and identifying Corynebacterium species candidates isolated from mice than biochemical methods. Because of limitations associated with the use of MALDI-TOF MS, more precise results will be obtained by complementing this approach with other methods when used for rapid identification testing.

Published: June 2022

River–lake interaction is important for maintaining biodiversity, yet it is vulnerable to hydrological alteration. The connectivity of the channel connecting Poyang Lake and the Yangtze River not only ensures the regular migration of fish but also makes Poyang Lake a feeding and fattening ground for them. Unfortunately, human activities have dramatically changed the hydrodynamic conditions of Poyang Lake, which is experiencing severe drought due to the obvious decline in the water level in autumn and winter, especially since 2003. However, the possible impacts of the changes in the water level on the habitats of migratory fish remain unclear due to the limitation of traditional techniques in spatiotemporal analysis. Here, we combined a hydrodynamic model and habitat suitability model to simulate variations in the suitable habitat area and their connectivity under different water-level conditions. The conditions for the migration pathway of the target fish were obtained by a hydroacoustic survey using the Simrad EY60 echosounder. The results showed that the change in water level will significantly affect the spatiotemporal change in the suitable habitats and their connectivity. In particular, we found the existence of two thresholds that play a dominant role in illuminating the connectivity of effective suitable habitats (HC). Firstly, the maximum value of the weighted usable area (WUA) and HC can be achieved when the water level is more than 16 m. Secondly, when the water level is between 10 and 16 m, the changes in the HC are sensitive and rapid, and the area flooded at this stage is called the sensitive area. HC is a crucial element in fish migration and habitat conditions. Under the condition of continuous drought in the middle reaches of the Yangtze River, our research contributes to clarifying the influence of water level on key habitats for fish and optimizes the practice of river–lake ecological management.
Study on the Mechanism and Prevention Method of Frozen Wall Maldevelopment Induced by High-Flow-Rate Groundwater
Authors: Wang Bin , Cao Yi , Rong Chuanxin , Cheng Hua
Published: June 2022

In order to solve the engineering problem of the increase in closure time or even the failure of closure of the frozen wall in the high-velocity permeable stratum, the maldevelopment mechanism of frozen walls induced by high-flow-rate groundwater was studied by a similar physical model test. The results show that the flowing groundwater reduced the heat transfer efficiency of the freezing pipes and changed the spatial distribution of the frozen area. The closure time of the frozen wall and the non-uniformity coefficient of the frozen wall thickness increased with the increase of the groundwater velocity. Based on the maldevelopment mechanism of frozen wall induced by groundwater, the artificial freezing scheme of permeable stratum with high seepage velocity was optimized. For the scheme of single-circle freezing holes, the optimization method of reducing the spacing between freezing holes and adding auxiliary freezing holes upstream of water flow was proposed. For the scheme of double-circle freezing holes, the optimization method of local variable pipe spacing was proposed. The optimization effect of several schemes was predicted and analyzed by numerical calculation, the results show that: in the optimized design scheme of single-circle freezing holes, both methods of local compaction and adding auxiliary freezing holes upstream could effectively shorten the closure time of frozen walls, and increase the maximum velocity at which the frozen wall can be closed. The optimum spacing of auxiliary freezing pipes under different groundwater velocity was obtained by calculation. In the optimized design scheme of double-circle freezing holes, the spacing of freezing holes in different regions was optimized and adjusted according to the degree of influence of water flow on freezing temperature fields under the condition that the number of freezing holes was kept constant. After adopting this optimization scheme, the limit flow velocity of frozen walls can be closed increased significantly. This study could provide reference for the arrangement of freezing holes in high-velocity permeable formation.

Published: June 2022

The research into rainfall-runoff plays a very important role in water resource management. However, runoff simulation is a challenging task due to its complex formation mechanism, time-varying characteristics and nonlinear hydrological dynamic process. In this study, a nonlinear autoregressive model with exogenous input (NARX) is used to simulate the runoff in the Linyi watershed located in the northeastern part of the Huaihe river basin. In order to better evaluate the performance of NARX, a distributed hydrological model, TOPX, is used to simulate the discharge as a reference, and runoff classification by cluster analysis is used to further improve the accuracy of runoff simulation. Based on the four statistics indexes of the Nash–Sutcliffe efficiency (NSE), correlation coefficient (CC), root mean square error (RMSE) and mean relative bias (Bias), the NARX model is capable of simulating the rainfall-runoff dynamic process satisfactorily, although there is a little underestimation of the peak flow. After runoff classification, underestimation has been improved, and discharge simulation driven by NARX based on runoff classification (C-NARX) is well consistent with the observation. It is feasible to take it as a promising method, which also can be seen as a good reference and replacement for the current rainfall-runoff simulation.
Short-Term Toxicity of Lanthanum to Embryonic and Yolk-Sac Stage Larvae of the Rare Minnow Gobiocypris rarus Ye & Fu, 1983
Authors: Su Liangxia , Hua Dong , Liu Jun , Hu Bing , Wang Jianwei
Published: June 2022

The wide use of rare-earth elements in China for aquacultural purposes and many other applications has resulted in their accumulation in the aquatic environment and has caused concern about their safety. In this study, we tested the toxicity of lanthanum (La (III)) to the early life stages (embryonic and sac-fry stages) of the rare minnow Gobiocypris rarus Ye & Fu, 1983. We exposed fertilized eggs to 0, 0.06, 0.13, 0.25, 0.50, 1.00, and 1.92 mg/L of La (III) until the yolk sac was exhausted in any group (at about 168 h of exposure). Exposure to 1.00 and 1.92 mg/L La (III) had obvious lethal effects on embryos, La (III) exposure also accelerated the development of embryos and had a significant inhibitory effect on the hatching rate after 96 h. As the exposure time increased, the larvae exhibited obvious yolk-sac edema, pericardium edema, spinal curvature, tail bending, and other symptoms of poisoning, including deflated swim-bladder. In general, these results clearly indicate that La pollutants hinder the development of rare minnow embryos and are acutely toxic to rare minnow larvae. Our finding would provide a theoretical basis for further research of relevant feed additive criteria for this fish.

Authors: Mitrakoudis Stavros G. , Alexiadis Minas C.
Published: June 2022

The emerging popularity of Plug-in Electric Vehicles (PEVs) is creating new connections between the transportation and electric sectors, and PEV charging will bring new opportunities and challenges to a system of growing complexity. The electrification of transport will increase energy security, reduce carbon emissions, and improve local air quality. The actual expansion of electric vehicles (EVs) will depend on several factors: the evolution of autonomy, the acquisition price, the charging process and infrastructure, etc. This paper provides a guide for simulating the accumulative load profile for EV charging on a national level. The importance of all the parameters and variables involved (deterministic or stochastic) is investigated. Detailed tables and references concerning the distribution of values and the composition of the EV fleet are provided. A multivariate probabilistic model is developed considering the EV classes, weekly and seasonal driving patterns, charging strategies, battery capacities, consumption per EV, etc., leading to an accurate estimation of aggregated EV charging demand. Finally, a net-metering scheme is proposed, in which a photovoltaic (PV) system of a certain size will be able to provide the annual energy needs of the first 10,000 EVs in the Greek market.

Large aperture ultrasonic arrays can be implemented by tiling together multiple pretested modules of high-density acoustic arrays with closely integrated multiplexing and buffering electronics to form a larger aperture with high yield. These modular arrays can be used to implement large 1.75D array apertures capable of focusing in elevation for uniform slice thickness along the axial direction which can improve image contrast. An important goal for large array tiling is obtaining high yield and sensitivity while reducing extraneous image artifacts. We have been developing tileable acoustic-electric modules for the implementation of large array apertures utilizing Application Specific Integrated Circuits (ASICs) implemented using 0.35μm high voltage (50 V) CMOS. Multiple generations of ASICs have been designed and tested. The ASICs were integrated with high-density transducer arrays for acoustic testing and imaging. The modules were further interfaced to a Verasonics Vantage imaging system and were used to image industry standard ultrasound phantoms. The first-generation modules comprise ASICs with both multiplexing and buffering electronics on-chip and have demonstrated a switching artifact which was visible in the images. A second-generation ASIC design incorporates low switching injection circuits which effectively mitigate the artifacts observed with the first-generation devices. Here, we present the architecture of the two ASIC designs and module types as well imaging results that demonstrate reduction in switching artifacts for the second-generation devices.

Published: June 2022

The purpose of this study was to investigate the effects of in ovo resveratrol in hatching quail eggs on hatching traits, organ weights and chick performance. The eggs were randomly distributed into four groups as non-injected group (PC; Positive control), 0.2 ml saline (NC; Negative control), 0.2 ml solution containing 1 nmol of resveratrol (R1) and 0.2 ml solution containing 4 nmol of resveratrol (R4). Hatchability of set eggs (HSE) and hatchability of fertile eggs (HFE), embryonic mortality (EM), chick hatching time, yolk sac weight (YSW), and chick performance characteristics were investigated. The effects of in ovo resveratrol administration on the HSE were insignificant. HFE decreased significantly with in ovo resveratrol treatment. All injected groups were adversely affected in terms of embryonic deaths. The effect of in ovo resveratrol application on chick hatch weight, and YSW (g, %), chick performance was insignificant. It was observed that in ovo resveratrol treatment had no significant effect on the hatching time, except at 408 h of incubation. As a result, in ovo resveratrol application had a negative effect on hatchability and EM, but did not have affected the hatching time, YSW and chick performance.

Authors: GÜVENC Mustafa , AYGÜN Ali
Published: June 2022

In this study, the effects of pre-storage coating of different ratios of gum arabic on hatching traits and chick growth performance were investigated. Treatment groups; eggs treated with 5% gum arabic were stored for 7 days (7-5G), eggs treated with 5% gum arabic were stored for 14 days (14-5G), eggs treated with 10% gum arabic were stored for 7 days (7-10G) and 10% gum arabic applied eggs were stored for 14 days (14-10G). After the gum arabic application, the eggs were stored at 13 °C with 75% humidity for 7 or 14 days. In the study, a total of 800 hatching eggs were used, with
200 eggs in each of the four groups. Regardless of the gum arabic application, eggs stored for 7 days have less egg weight loss than eggs stored for 14 days (P<0.05). There were no statistically significant differences found for hatchability of set eggs (HSE). The highest hatchability of fertile eggs (HFE) were found in 7-5G (88.22%) and lowest HFE was observed in 14-10G (73.96%) (P<0.05). In terms of embryonic mortality, the differences between the groups at days 1-9 and 17-18 were insignificant. Embryonic mortality was highest (16.49%) in the 14-10G group in the 10-16-day period (P<0.05). No statistically significant differences were observed among groups for chick body weight at hatch and yolk sac ratio (YSR). The lowest relative growth was found in the 14-10 G group (P<0.05). As a result, 5% gum arabic application and storage for 14 days can be recommended for long-term storage of
eggs since it does not have a negative effect on hatchability, embryonic mortality, or chick growth performance.

Published: June 2022

Türkçe öğretiminin temel amacı anlama ve anlatma becerilerinin kazandırılması ve geliştirilmesidir. Eğitimde ölçme ve değerlendirmelerin bir parçası olan sorular bu temel amaca erişilip erişilmediğini kontrol etmenin en önemli araçlarındandır. Bir kontrol mekanizması olması dışında farklı düzeyde bilişsel süreçleri teşvik eden soruların anlama becerilerini geliştirmede etkili olduğunu ortaya koyan çalışmalar bulunmaktadır. Diğer yandan yapılan ulusal alan yazın taraması anlama becerisi alanında hazırlanan soruların talep ettiği bilişsel süreçler bakımından daha çok temel düzeyde yığıldığını göstermektedir. Bu noktada taksonomiler eğitimcilerin etkili sorular hazırlamasına rehberlik edebilecek temel kaynaklar olarak ortaya çıkmaktadır. Bu çalışmanın amacı okuyuculara Bloom ve Barrett taksonomisine ve gelişim süreçlerine dair temel bilgileri sunmak ve soru hazırlarken bu taksonomilerden faydalanmak isteyenlere rehberlik etmektir. Derleme türündeki bu makalede Bloom ve Barrett taksonomisinin ortaya çıkış ve gelişim süreçleri ile bu taksonomilerin basamaklarının tanımlarına ve kullanıcılara sundukları fırsat ve sınırlılıklara değinilmektedir. Çalışmada her iki taksonominin basamakları karşılaştırmalı olarak incelenmiştir. Böylece eğitim öğretimin farklı kademe ve disiplinlerinde daha yaygın olarak kullanılan Bloom taksonomisinden hareketle onun kadar yaygın olmayan Barrett taksonomisinin okuyucu zihninde somutlaşmasını sağlamak hedeflenmiştir. Barrett taksonomisinin esas amacı okuma anlamlandırma becerisinin sınıflandırılması olduğundan bu durumun Türkçe öğretimi alanındaki araştırmacı ve uygulayıcılara fayda sağlayacağı düşünülmektedir.

Ayrıca hem öğretmen hem de öğrencilerin ana fikir bulma becerisine ilişkin kavram yanılgılarının olduğu sonucuna ulaşılmıştır.
Contextualización e ideologización del conocimiento científico-tecnológico nacional en el programa estético de Mundo Atómico (1950-1955)
Authors: Massariol Diego Nicolás
Published: June 2022

En el siguiente trabajo estudio las características del diálogo ciencia-política entre 1950 y 1955 a partir de un corpus de textos visuales producidos, financiados y distribuidos por el Estado argentino en la revista Mundo Atómico. Para ello me inscribo en los lineamientos teóricos de una semiótica general de la cultura y empleo las herramientas metodológicas de la semiótica textual para analizar la modelización de los significados públicos producida en las ilustraciones de la revista con el objetivo general de indagar las coordenadas contextuales e ideológicas del programa científico-tecnológico oficial. En este marco sostengo que estos textos habrían formateado ideológicamente el conocimiento en un nacionalismo social cristiano secularizado hacia las bases de un humanismo coincidente con el gobierno. Para ello, primero estudio y describo las políticas públicas orientadas al campo científico-tecnológico durante el primer peronismo para explicar la centralización y la heteronomía producidas entonces. Luego propongo una actualización interpretativa del corpus a partir de la detección de sus modos de producción sígnica en pos de indagar en la orientación común de sus topics. Finalmente, presento los hallazgos, articulo los resultados y ensayo conclusiones referidas a la complementariedad operativa entre los programas epistemológicos y estéticos en la expansión de los proyectos políticos.

Bankrobotics: Artificial Intelligence and Machine Learning Powered Banking Risk Management : Prevention of Money Laundering and Terrorist Financing
Authors: Prisznyák Alexandra
Published: June 2022

Based on a country study related to money laundering and terrorist financing, the Financial Action Group downgraded Hungary’s compliance with Recommendation R15 (use of new technologies). At the same time, between 2020 and 2021, the Magyar Nemzeti Bank imposed fines on several commercial banks operating in Hungary for shortcomings on complying with money laundering and terrorist financing regulations. As a gap-filling analysis, the study examines supervised (classification, regression), unsupervised (clustering, anomaly detection), and hybrid machine learning models and algorithms operating based on highly unbalanced dataset of anti-money laundering and terrorist financing prevention of banking risk management. The author emphasizes that there is no one ideal algorithm. The choice between machine learning algorithm is highly determined based on the underlying theoretical logic and additional comparative. Model building requires a hybrid perspective of the give business unit, IT and visionary management.
A feltörekvő piaci szuverénfelár megemelkedése a Covid–19 utáni világgazdaságban

Published: June 2022

A Covid–19 által okozott gazdasági leállások és zavarok nyomán ismét megjelent a leértékelődési nyomás és a szuverénfelár növekedése miatti fenyegetés a feltörekvő piacokon, ami szükségessé teheti a nemzetközi pénzügyi védőháló intézményeinek beavatkozását. Tanulmányunk első felében ezért számba vesszük az IMF és a nyolc regionális pénzügyi alap („Regional Financial Arrangement” – RFA) válságellenes intézkedéseit. Ezt követően megvizsgáljuk, hogyan befolyásolta a feltörekvő piaci szuverénfelár változását a piaci hangulat romlása: a globális gazdasági növekedéssel, a kulcsdevizában történő finanszírozás költségével, az államcsőddel kapcsolatos várakozások és a devizaárfolyam, valamint az output növekedésének változásai. Ehhez strukturális panel vektor autoregressziós modellt használtunk. Megállapíthattuk, hogy a szuverénfelár változása alapvetően a piaci várakozások változását követte le az országspecifikus növekedési és finanszírozási tényezők mellett. Mindez felhívja a figyelmet az IMF-, illetve az RFA-beavatkozások jelentőségére.
A kriptovaluták árfolyamának alakulása eseményelemzés alapján
Authors: Czeczeli Vivien , Vilonya Martin
Published: June 2022

A kriptovaluták piacának dinamikus fejlődésével párhuzamosan fontos pénzügyi és közgazdasági kérdések merülnek fel. A jelen kutatás fő fókusza a kriptovaluták árfolyamának alakulására irányul. A szakirodalmi bázis feltárása nyomán kiemelt figyelmet kapott a kriptopiac más eszközosztályok (arany, részvény, deviza) piacával való összehasonlítása, a kapcsolódási pontok azonosítása. Ezt követően a cikk a 2020 utáni időszakra fókuszálva, eseményelemzés (event study) segítségével igyekszik feltárni, hogy a két legnagyobb piaci kapitalizációval rendelkező kriptovaluta (a bitcoin és az ethereum) hogyan reagált néhány választott eseményre. Ez elsősorban a kriptovaluták működésének alapját képező rendszerek elleni hackertámadásokat jelenti, illetve a szabályozásukhoz, az alkalmazásukhoz kapcsolódó egyes lépéseket. Összességében megállapítottuk, hogy a hackertámadások nem hatottak szignifikánsan a két vizsgált kriptovaluta árfolyamára. A szabályozói lépések hatásai az árfolyamokra vegyesek, ám a szignifikáns hatások is rövid lefolyásúnak tekinthetők.
Az eszközvásárlások, a pénzmennyiség és az infláció kapcsolata a 2007 és 2022 közötti időszakban a Federal Reserve példáján keresztül
Authors: Csiki Máté
Published: June 2022

A 2008-as válságot és a 2020-as Covid–19-járványt követő nagy eszközvásárlási programok a pénzmennyiség-aggregátumok jelentős bővülését okozták, aminek mentén az infláció és a pénzmennyiség kapcsolatának vizsgálata (újra) felértékelődött. A tanulmányban az Amerikai Egyesült Államokra vonatkozó adatok alapján vizsgálom 2007 és 2022 között a mennyiségi lazítás okozta pénzaggregátumváltozásokat, a jegybanki politika végrehajtásának keretrendszerét bőséges tartalékok mellett, illetve ezeknek az árszínvonalra gyakorolt hatását vektor-autoregresszív modell alkalmazásával. A tanulmány által feldolgozott időszak felöleli a 2020 utáni járványhelyzetet, azonban a rendelkezésre álló időszak korlátozott hossza és a hatások bizonytalansága miatt a tanulmány fókusza a járvány előtti folyamatokon van. Az időszakban a pénzmennyiség jelentős bővülése okozta inflációs félelmek nem igazolódtak a jegybanknál elhelyezett feles tartalékokban kicsapódó bankrendszeri likviditás, az átalakuló monetáris politikai operatív keretrendszer, valamint a negatív kibocsátási rés hatására. Azonban a modell szerint a pénzaggregátumok sokkjai az inflációs várakozásokba beépülnek, vagyis az eszközvásárlások okozta pénzmennyiség-változási folyamatok a vizsgált jegybank esetében segíthetik a középtávú inflációs cél elérését.
Az adóamnesztia magatartási vonatkozásai és hatása tizenkét ország vizsgálatán keresztül
Authors: Erdoğdu M. Mustafa , Akar Sevda
Published: June 2022

A jelen tanulmány az adóamnesztia elméleti és empirikus kutatásáról nyújt áttekintést a vonatkozó előnyök és hátrányok mérlegelésével. Kutatásunkban arra keressük a választ, hogy az adóamnesztia közép- és hosszú távon ösztönzi-e az adózási fegyelmet az egyes tanulmányok megállapításaival összhangban, vagy igazságtalan és romboló hatása miatt inkább gátolja az adófegyelem kialakulását. Tanulmányunkban tizenkét országra vonatkozóan – elsősorban Törökországra fókuszálva – vizsgáljuk az adóamnesztia-programok adóbevétel/GDP arányra gyakorolt hatásának elérhető adatait a Giniegyüttható értékeivel együtt. A tanulmány célja az adóamnesztiával szembeni – mind az adóbevétel, mind az adóigazságosság szempontjából – kedvezőbb alternatívák azonosítása. A kutatás eredményei azt mutatják, hogy míg az adóamnesztia rövid távú bevételi hatása bizonytalan, az adóigazságosságra és jövedelemelosztásra gyakorolt negatív hatása közép- és hosszú távon szinte bizonyosnak mondható. A kutatás arra is rámutat, hogy az adóamnesztiák hátterében többnyire aligha az adóbevétel növelésének legfőbb szándéka áll.
Experiencias educativas de población indígena en tiempos de pandemia
Authors: Mazas Rodríguez Martha Viridiana , Leyva Domínguez Paola
Published: June 2022

El objetivo de la presente investigación es conocer las vivencias indígenas en tiempos de pandemia en la Sierra Norte del estado de Oaxaca con relación a la educación. Se trata de un estudio de corte cualitativo descriptivo para el cual se aplicaron de manera aleatoria entrevistas semiestructuradas a 2 docentes, 3 estudiantes y 3 padres de familia. Los resultados encontrados luego del análisis cualitativo demuestran las dificultades sufridas por los padres de familia en cuanto a la adquisición de recursos tecnológicos debido a que son de escasos recursos; en cuanto a los docentes no hubo buena comunicación con los estudiantes y consideran que la educación a distancia no dio buenos resultados; los estudiantes, por su lado, enfrentaron problemas de conexión y no contaban con las herramientas necesarias; todo ello nos permite inferir que el rezago educativo que presentarán los estudiantes será muy alto en esta comunidad indígena.
