The present research analyses the epidemiological bases, the methodology approach and the utility of the Geo-Covid Cartographic Platform to face COVID-19 transmission at an intra-urban scale. Geo-Covid is based on the study of the main drawbacks and limitations of the current risk maps, and the proposed hazard mapping methodology is presented as an alternative approach with a high spatial-temporal accuracy. It is based on 1) the map of neighborhood active focuses of contagion, which are classified according to several hazard indexes, 2) the map of highly-transited areas by potential asymptomatic positives cases and 3) the map of Points of Maximum Risk of contagion. In order to test the effectiveness of the proposed methodology for mapping COVID-19 hazard and risk, it has been applied to Málaga City (Spain) during several stages of the epidemic in the city (2020 and 2021). The neighborhood focus of contagion is proposed as the basic spatial unit for the epidemiological diagnosis and the implementation of mitigation and control measures. After the analysis, it has been concluded that the proposed methodology, and thus, the maps included in the Geo-Covid Cartographic Platform allow a realistic and rigorous analysis of the spatial distribution of the epidemic in real-time.

Abstract
The coastal area of the southern Lake Baikal with the population over 35,000 people remains an attractive spot for both tourists and local residents. Despite high anthropogenic impact, a detailed assessment of water quality in this area has not been performed so far. Here, we performed a comprehensive evaluation of the quality of the surface, bottom and interstitial water in rivers, lacustrine water and wastewater in the southern Lake Baikal region. We analyzed 37 samples for the presence of fecal enterococci, Escherichia coli and assessed their hydrochemical parameters: concentrations of nutrients (nitrate-N, nitrite-N, ammonium-N and phosphate-P), dissolved oxygen and amount of ions (HCO3− + SO42− + Cl− + Ca2+ + Mg2+ + Na+ + K+). In addition, the temperature, pH and electrical conductivity were also measured. We found that multiple areas around South Baikal suffer from microbiological and hydrochemical pollution. We conclude that ecological situation in this area requires immediate attention from local authorities, more efficient wastewater management systems should be constructed in the settlements. We also conclude that interstitial waters from the lake's splash zone represent an effective and sensitive indicator of sanitary-microbiological and hydrochemical pollution and their analysis can be included in the standard protocol of water quality assessment for all types of water bodies.

Abstract

Objective
There is a dilemma of ibuprofen treatment with patent ductus arteriosus (PDA) as to how and when to treat. We aimed to clarify this issue in very preterm infants (VPIs; < 32 weeks).

Methods
This retrospective study included 1 659 VPIs who were diagnosed with PDA according to echocardiographic examinations and cardiovascular dysfunction scoring system (the CVD scoring). The VPIs were classified into six groups (A1, A2, A3, B1, B2, and B3) based on CVD scores (A, < 3, and B, ≥ 3), and treatment with ibuprofen for PDA (1, conservational management; 2, early ibuprofen treatment; and 3, late ibuprofen treatment). Treatment was stopped when PDA was closed, CVD score was zero or PDA needed ligation.

Results
VPIs with CVD scores < 3 had most PDA closure without surgery, and early ibuprofen treatment did not significantly affect PDA closure. VPIs with CVD scores ≥ 3 had some PDA closure after 2 courses of treatment, but closure rates decreased linearly with ibuprofen course (1st 75.2%, 2nd 62.3%, 3rd 50.0%, P < 0.0001), and early ibuprofen treatment (group B2) did not increase PDA closure compared to late ibuprofen treatment (group B3). In these same infants, the longer they were in CVD scores ≥ 3, the more the complications of preterm were increased (retinopathy of prematurity ROP 1st 16.5%, 2nd 23.8%, 3rd 29.6%, P = 0.016; bronchopulmonary dysplasia BPD 1st 15.5%, 2nd 26.7%, 3rd 33.8%, P < 0.0001; intraventricular hemorrhage IVH 1st 20.4%, 2nd 32.4%, 3rd 23.8%, P = 0.015).

Conclusion
Ibuprofen is suggested for PDA closure when the PDA reopens or has developed into the stage when the CVD score ≥ 3.
The Roles of Female Involvement and Risk Aversion in Open Access Publishing Patterns in Vietnamese Social Sciences and Humanities
Authors: Nguyen Minh-Hoang , Nguyen Huyen Thanh Thanh , Ho Manh-Toan , Le Tam-Tri , Vuong Quan-Hoang 
Published: December 2021

Abstract

Purpose
The open-access (OA) publishing model can help improve researchers’ outreach, thanks to its accessibility and visibility to the public. Therefore, the presentation of female researchers can benefit from the OA publishing model. Despite that, little is known about how gender affects OA practices. Thus, the current study explores the effects of female involvement and risk aversion on OA publishing patterns among Vietnamese social sciences and humanities.

Design/methodology/approach
The study employed Bayesian Mindsponge Framework (BMF) on a dataset of 3,122 Vietnamese social sciences and humanities (SS&H) publications during 2008–2019. The Mindsponge mechanism was specifically used to construct theoretical models, while Bayesian inference was utilized for fitting models.

Findings
The result showed a positive association between female participation and OA publishing probability. However, the positive effect of female involvement on OA publishing probability was negated by the high ratio of female researchers in a publication. OA status was negatively associated with the JIF of the journal in which the publication was published, but the relationship was moderated by the involvement of a female researcher(s). The findings suggested that Vietnamese female researchers might be more likely to publish under the OA model in journals with high JIF for avoiding the risk of public criticism.

Research limitations
The study could only provide evidence on the association between female involvement and OA publishing probability. However, whether to publish under OA terms is often determined by the first or corresponding authors, but not necessarily gender-based.

Practical implications
Systematically coordinated actions are suggested to better support women and promote the OA movement in Vietnam.

Originality/value
The findings show the OA publishing patterns of female researchers in Vietnamese SS&H.
Public Reaction to Scientific Research via Twitter Sentiment Prediction
Authors: Shahzad Murtuza , Alhoori Hamed 
Published: December 2021

Abstract

Purpose
Social media users share their ideas, thoughts, and emotions with other users. However, it is not clear how online users would respond to new research outcomes. This study aims to predict the nature of the emotions expressed by Twitter users toward scientific publications. Additionally, we investigate what features of the research articles help in such prediction. Identifying the sentiments of research articles on social media will help scientists gauge a new societal impact of their research articles.

Design/methodology/approach
Several tools are used for sentiment analysis, so we applied five sentiment analysis tools to check which are suitable for capturing a tweet's sentiment value and decided to use NLTK VADER and TextBlob. We segregated the sentiment value into negative, positive, and neutral. We measure the mean and median of tweets’ sentiment value for research articles with more than one tweet. We next built machine learning models to predict the sentiments of tweets related to scientific publications and investigated the essential features that controlled the prediction models.

Findings
We found that the most important feature in all the models was the sentiment of the research article title followed by the author count. We observed that the tree-based models performed better than other classification models, with Random Forest achieving 89% accuracy for binary classification and 73% accuracy for three-label classification.

Research limitations
In this research, we used state-of-the-art sentiment analysis libraries. However, these libraries might vary at times in their sentiment prediction behavior. Tweet sentiment may be influenced by a multitude of circumstances and is not always immediately tied to the paper's details. In the future, we intend to broaden the scope of our research by employing word2vec models.

Practical implications
Many studies have focused on understanding the impact of science on scientists or how science communicators can improve their outcomes. Research in this area has relied on fewer and more limited measures, such as citations and user studies with small datasets. There is currently a critical need to find novel methods to quantify and evaluate the broader impact of research. This study will help scientists better comprehend the emotional impact of their work. Additionally, the value of understanding the public's interest and reactions helps science communicators identify effective ways to engage with the public and build positive connections between scientific communities and the public.

Originality/value
This study will extend work on public engagement with science, sociology of science, and computational social science. It will enable researchers to identify areas in which there is a gap between public and expert understanding and provide strategies by which this gap can be bridged.

Published: December 2021

The fashion industry is included in the top three creative industry sectors in Indonesia. The development of the fashion industry is also supported by various parties and is also enlivened by the distinctive fashion of Indonesian traditional fabrics. Several traditional Indonesian fabrics, such as batik, lurik, Lombok songket have successfully penetrated the international market, so the opportunity to continue developing the fashion industry with traditional fabrics is still large. One of them is to use a typical Sumba woven cloth which is not gaining popularity with Sumba as a tourist destination. Therefore, this research was conducted with the aim of digging deeper into the factors that shape the brand awareness of Sumba woven fabrics. This research was conducted using a qualitative approach and phenomenological methods, with data collection using the Focus Group Discussion (FGD) technique. The results showed that the factors that formed brand awareness of Sumba woven fabrics were divided into two, namely internal and external factors. Internal factors are factors that come from the product itself, such as motif, price, color, age of fabric, quality, craftsmen. While external factors come from outside the product, including the power of word of mouth, organizing events (exhibitions), government involvement (regional and central), and showing the identity of the wearer. Industri fashion termasuk dalam tiga besar sektor industri kreatif di Indonesia. Perkembangan industri fashion ini juga didukung berbagai pihak, serta turut diramaikan dengan fashion khas kain tradisional Indonesia. Beberapa kain tradisional Indonesia, seperti batik, lurik, songket Lombok telah berhasil menembus pasar internasional, sehingga peluang untuk terus mengembangkan industri fashion dengan kain tradisional masih besar. Salah satunya adalah dengan menggunakan kain tenun khas Sumba yang kurang mendapatkan popularitas dengan Sumba sebagai destinasi wisata. Oleh karenanya, penelitian ini dilakukan dengan tujuan untuk menggali lebih dalam mengenai faktor yang membentuk brand awareness kain tenun Sumba. Penelitian ini dilakukan dengan menggunakan pendekatan kualitatif dan metode fenomenologi, dengan pengumpulan data menggunakan teknik Focus Group Discussion (FGD). Hasil penelitian menunjukkan bahwa faktor yang membentuk brand awareness atas produk kain tenun Sumba dibedakan menjadi dua, yaitu faktor internal dan eksternal. Faktor internal merupakan faktor yang berasal dari produk sendiri, seperti motif, harga, warna, usia kain, kualitas, pengarajin. Sedangkan faktor eskternal berasal dari luar produk, meliputi kekuatan dari word of mouth, penyelenggaraan event (pameran), keterlibatan pemerintah (daerah dan pusat), dan menunjukkan identitas pemakainya.

Влияние турбулентности и восходящих потоков воздуха на дочерние продукты распада радона
Authors: Zelinskiy A.S. , Yakovlev G.A. 
Published: December 2021

In this paper, a simulation of the distribution of radon progeny over the height of the atmosphere, depending on the amount of turbulent mixing and the vertical air velocity, is presented. The obtained results are compared with the change in the activity ratio of Bi-214/Pb-214 isotopes recorded in rainwater during 3-year observations in Prague. It is found that the reasons for the most common values of Bi-214/Pb-214 can be the height of the lower edge of the cloud of 0.2-1.4 km and the vertical air velocity of 0.1 – 0.2 m / s. The ratio changes slightly from changes in the turbulent mixing, the value of the vertical air movement makes the main contribution. It is found that with the increase in the intensity of rain, a shift in the radioactive equilibrium should occur due to an increase in the velocity of vertical air. Atmospheric inversion is able to balance the volumetric activities of the descendants of atmospheric radon, atmospheric inversion can be identified by the equality between the activities of the radon progeny in the atmosphere at different altitudes or in rainwater. It is shown that the search for the relationship between precipitation intensity and gamma radiation is expose to error, without taking into account the influence of the АBi−214/АPb−214 ratio, due to the unequal activities of the atmospheric isotopes Bi-214 and Pb-214. This error of 7-14% when using gamma radiometry, and of 5-9% when using dosimeters is estimated.
олучены результаты моделирования распределения дочерних продуктов радона в атмосферном столбе по высоте, объясняющие изменение концентраций радионуклидов в дождевой воде в зависимости от высоты нижней кромки облаков. Значения соотношений активностей АBi−214/АPb−214 радионуклидов дождевой воды от 0.6 до 0.8, могут возникать при высоте нижней кромки облаков от 0.2 до 1.4 км и адвекции от 0.1 до 0.2 м/с соответственно. Произведена оценка шибки от 7 до 14%, возникающая при использовании гамма радиометров, и от 5 до 9% — дозиметров, во время осадков с целью поиска корреляции роста гамма-фона и интенсивности жидких ливневых осадков.
