Authors: Adel Kareem , Elhakeem Ahmed , Marzouk Mohamed 
Published: September 2022

Abstract
Integrating Artificial Intelligence (AI) with Blockchain Technology (BT) is deemed the fourth generation of BT applications (Blockchain 4.0). This generation has gained considerable attention from the research community. Such attention has led to a vast amount of scientific literature. However, a comprehensive quantitative analysis of this literature is still missing. The present study conducts a scientometric analysis to explore and characterize the development track and trends of BT-AI research. Using the Web of Science (WoS) Core Collection database, a total of 956 peer-reviewed journal articles were identified between 2016-2021 and extracted for analysis, while employing VOSviewer, CiteSpace, and Biblioshiny as software tools. First, the publication trend was analyzed, and the pivotal articles were identified. Second, the scientific collaboration networks were analyzed and mapped to identify the key researchers, countries, and organizations. Third, the sources’ productivity and citation were analyzed and mapped to identify the dependable sources of information and the best-fit sources for publishing the BT-AI studies. Fourth, the conceptual and intellectual structures for the BT-AI literature were analyzed and visualized using keywords co-occurrence, keywords thematic evolution, and reference co-citation analyses to explore and identify the research hotspots and emerging themes. The findings of this study can help in further familiarizing new researchers with BT-AI literature and assist practitioners, policy-makers, and editors to focus on the promising and arising BT-AI trends for further development.

Abstract
Solving the problem of agricultural water use efficiency is an effective means to understand the agricultural ecological civilization and food security. In order to balance the relationship between agricultural water efficiency and regional economic size, this study examines the agricultural water use efficiency in China based on the Super-SBM model of unexpected output. At the same time, the Spatial Durbin Model (SDM) was introduced to analyze the spatial spillover effect and try to find ways to improve agricultural water use efficiency from the perspective of influencing factors. The present study used the panel data of 30 provinces in China from 1998 to 2018 to obtain empirical results. The results show that (1) China's agricultural water resources’ utilization efficiency in 21 years has not remained high: the results showed that it was 0.496 in 1998, 0.572 in 2008, and 0.657 in 2018, but it is slowly rising which explains that the low efficiency is mainly caused by the low pure technical efficiency. (2) The overall agricultural water use efficiency in China is in a situation of spatial agglomeration but there has been a trend of shifting positive correlations to negative correlations among neighboring provinces. It found that in 1998, the sum of the number of `High-high agglomeration type' and `low-low agglomeration type' provinces was 20, and the sum of `low-high agglomeration type' and `high-low agglomeration type' provinces was 10. In 2018, the total number of `high-high agglomeration type' and `low-low agglomeration type' provinces decreased to 12, while the total number of `low-high agglomeration type' and `high-low agglomeration type' provinces increased to 18, which specifically manifested as a negative spillover effect. (3) During the research period, the province's agricultural fixed asset investment, fiscal expenditure on agriculture, forestry, and water affairs, the number of years of education of rural residents and the increase in crop sown area have positive impacts on the efficiency of agricultural water use in the province. Meanwhile the transfer of labor and increase in the disposable income of rural residents reduced the efficiency of agricultural water use in the province. Fixed agricultural investment, labor transfers, and financial expenditures for agriculture, forestry, and water affairs in neighboring provinces have negative impacts on the province's agricultural water use efficiency. The impact is specifically manifested as a negative spatial spillover effect. As a result, China's agriculture will move towards healthy and green development. Therefore, the efficiency of agricultural water use needs to be comprehensively improved.
The role of degree of opening in comprehensive water efficiency, derived from SHAN model
Authors: Shan Huang , Ying Kong 
Published: September 2022

Abstract
China's reform and opening-up strongly impact its local water resources. The most frequently stated problems are water supply scarcity and pollution issues in China's Yangtze River. What is not yet clear is the correlation between comprehensive water efficiency and its sub-stage efficiencies, water utility efficiency, and water governance efficiency. This study aims to investigate water utility and water governance together. This paper provides a fresh perspective on developing an improved DEA method called the SHAN model that evaluates and decomposes the comprehensive water efficiency to water utility efficiency and water governance efficiency for 30 cities in the Yangtze River Basin from 2005 to 2015. The SHAN model is a modified RAM Network DEA model with the extra consideration of Super SBM and undesirable output. A Tobit model will be adopted to analyze the relationship between comprehensive water efficiency and its sub-stages. This paper uses panel quantile regression to investigate the impact of the degree of opening and other efficiency determinants. The results show that the value of comprehensive water efficiencies in most cities along the Yangtze River Basin are lower than 1, as well as the water utility efficiencies and water governance efficiencies. The results indicate that the government should significantly improve water resource utilization and pollution problems. The findings also show that the degree of opening, population density, GDP per capita, urbanization, and industrial structure positively influence comprehensive water efficiency. Population urbanization lag has negative impacts on the comprehensive water efficiency. The Tobit regression results show that the water resource utilization efficiency and water resource management efficiency are 1.435 and 0.227, respectively. This result indicates that the water utility stage has a more significant effect on comprehensive water efficiency.

Published: September 2022

Abstract
This study focused on the water quality of a river in Wuhan City, China, which is surrounded by ponds that were transformed into a bypass multipond wetland system to improve river water quality. The bypass multipond wetland system included surface-flow artificial wetlands, modified partition ponds, aeration reoxygenation ponds, ecological ponds, and other processes. After the stable operation of the process, the water transparency was higher than 60 cm and the dissolved oxygen (DO) was higher than 5 mg/L, while the ammonia nitrogen (NH3-N) concentration was less than 1.0 mg/L, total phosphorus (TP) was lower than 0.2 mg/L, and chemical oxygen demand (COD) was lower than 20 mg/L, achieving the treatment target. After monitoring the results of each process, the process which best enhanced the water transparency enhancement was the surface-flow of the artificial wetlands and ecological ponds. The aeration reoxygenation pond had the best effect on DO enhancement. The processes that most affected NH3-N and TP removal were the surface-flow artificial wetlands and ecological ponds. The modified parthenogenic pond had the greatest effect on COD removal. The bypass multipond wetland system not only improved the river water quality but also enhanced the river landscape, and can act as a reference for similar river water quality improvement actions.

Published: September 2022

Abstract:
Trace elements were suggested to have a main role in modulating cognitive function. However,
there are several controversial findings regarding the association between serum trace element
concentration and cognitive function in patients with cognitive disorders. Thus, this study aimed to
evaluate the changes in serum trace element concentrations in elderly with cognitive dysfunction versus
the participants with normal cognitive function. This cross-sectional study included 191 older
adults over 60 years from Birjand County, Iran. Participants were assessed for cognitive performance
and serum trace elements concentration, including aluminum (AL), cobalt (Co), cadmium (Cd),
Chrome (Cr), copper (Cu), Iron (Fe), magnesium (Mg), manganese (Mn), selenium (Se) and zinc (Zn).
Our findings showed no significant difference in the serum concentration of AL, Co, Cr, Zn, Fe, Mg,
Mn, and Se of elderly with cognitive dysfunction versus the subjects with normal cognitive function.
However, the concentration of Cu significantly increased in the serum of the elderly with cognitive
dysfunction versus participants with normal function. In conclusion, our study indicated an increase in
the serum concentration of Cu in the elderly with cognitive dysfunction in the sample of the Birjand
Longitudinal Aging Study. However, due to the main limitations of our study, including low sample
size and cross-section design, these findings should be interpreted with caution.

Published: September 2022

Introduction:
Few studies have developed tools to evaluate COVID-19 vaccine literacy (VL), especially in Asia. In this study, an online tool was utilized to assess COVID-19 VL, vaccine fear (VF), vaccine hesitancy (VH), and vaccine acceptance (VA) among village health volunteers (VHVs) in Thailand.

Methods:
A cross-sectional online questionnaire was distributed to 210 VHVs between 10th to 14th September, 2021 to assess their VL, VF, VH, and VA levels. Item objective congruence (IOC) and Cronbach’s alpha were used to estimate the validity and reliability of the questionnaire. The two-independent sample t-test, Wilcoxon rank-sum test, ANOVA, and the Kruskal-Wallis test were employed to compare differences between the scores. Pearson correlation and Spearman’s rank correlation were used to estimate the correlation of the scores.

Results:
The online questionnaire showed high validity, with IOC values over 0.70 and reliability over 0.87 for all items. Median scores of VL, VF, and VH for the 210 participants were high (VL 2.92 and VF 2.5 out of a maximum of 4, and VH 2.43 out of a maximum of 5). The mean VA score was low (0.21 out of a maximum of 1) and significantly different between demographic variables. A significant correlation was found between VL and VH and VF and VA.

Conclusion:
The online questionnaire showed high values of validity and reliability. This tool proved to be beneficial for evaluating VL, VF, VH, and VA in Thailand. Further studies using a larger population are required to verify these results.
#ChegadeAssedio

Published: September 2022

Argumentar sobre modos de pensar os feminismos latino-americanos se faz necessário a partir de um viés decolonial formado por autoras do Sul Global. Aliar tais saberes teóricos às práticas ativistas de mulheres dentro e fora das redes torna-se salutar para compreender como suas realidades violentas vêm sendo combatidas. Deste modo, em nosso trabalho propomos refletir sobre usos e repercussões do ativismo digital no combate ao assédio sexual sofrido por mulheres na América Latina. Para tanto, selecionamos as campanhas brasileiras #ChegadeFiuFiu e #MexeuComUmaMexeuComTodas com o intuito de examinar se as ações por elas realizadas resultaram em efeitos significativos diante da pauta em questão. Os resultados preliminares apontam que o intercruzamento entre práticas e saberes reverberaram em novas formas de organização política de mulheres, por vezes eficientes no enfrentamento à violência sexual em espaços públicos.

Estudos sobre a sociologia em tempos de desordem
Authors: Weninghamp Júnior José Ernesto 
Published: September 2022

Atualmente o Brasil e o mundo se vêm atrelados a uma situação, onde as questões da sociedade e da Sociologia, deixaram de possuir importância no contexto total de vida. Isso ocorre, pois, o meio político começou a sofrer um processo de corrosão, levando grande parte da população a questionar direitos básicos de sociedade que foram conquistados com muita luta e suor. Essa situação que passou a existir desencadeou uma divisão sem precedentes na população, escancarando situações nunca antes vistos no atual século. Em conjunto a tudo isso encontra-se a sociedade e os estudos da Sociologia, que tentam trazer luz sobre as situações que são vividas atualmente, e que em grande parte são reflexos de um passado não tão distante. Seja no Brasil ou em Portugal, a sociedade vive de momentos, ora calmos, democráticos e baseados na ciência, ora desumanos, complexos e antidemocráticos.
Online sexual harassment among young female students in Ward 10, Baneshwor, Kathmandu, Nepal
Authors: Sharma Krishna , Shrestha Vijaya Laxmi , Shrestha Prabin , Shrestha Ram Bahadur 
Published: September 2022

Background
Incidences of sexual harassment that occur over the internet are growing
with the development of new technologies and virtual communities. This
is a hidden form of sexual harassment that emerges unpredictably and
poses a public health challenge. The objective of this study was to
determine the extent of online sexual harassment experienced by female
students (aged 15–24 years) in Baneshwor (Ward 10), Kathmandu, Nepal.
Methods
A total of 382 female students aged 15–24 – high school (10+2 level)
to bachelor level – participated in a quantitative cross-sectional
study. A semistructured questionnaire, in the English language, was
designed for selfadministered data collection. It comprised six
sections: sociodemographic information, internet accessibility, use of
social media, experience of online sexual harassment, student’s
awareness and online behaviour.
Results
Around 66.5% of respondents reported having been exposed to online
sexual harassment at least once, and most of the respondents (73.2%)
had been exposed to online sexual harassment multiple times. Just under
twothirds (62.8%) of the respondents had been exposed to online sexual
harassment before they reached 18 years of age. The mean age at which
the young women experienced online sexual harassment was 18.94±1.79
years. Respondents studying in high school (10+2 level), those residing
in urban areas and those accepting friend requests on social media from
people they did not know offline were at higher risk of experiencing
frequent online sexual harassment (P=0.000, P=0.011, and P=0.013
respectively).
Conclusion
The rate of online sexual harassment recorded was high. This shows an
urgent need to address the problem; universities and the government need
to play a part. A new module of comprehensive sexuality education for
virtual communication is suggested as an addition to current academic
curriculums.

Authors: Zhou Chun , He Panpan , Ye Ziliang , Zhang Yuanyuan , Zhang Yanjun , Yang Sisi , Wu Qimeng , Liu Mengyi , Nie Jing , Qin Xianhui 
Published: September 2022

OBJECTIVE
The prospective relation of vitamin D status with the risk of chronic kidney diseases (CKD) remains uncertain. We aimed to examine the association of serum 25-hydroxyvitamin D (25OHD) with new-onset CKD in participants with and without diabetes at baseline and examine the potential modifications by genetic susceptibility on the association.

RESEARCH DESIGN AND METHODS
Included were 348,243 adults from the UK Biobank without prior CKD at baseline. Serum 25OHD concentrations were measured by chemiluminescent immunoassay method. Genetic risk score of CKD was calculated by 263 single nucleotide polymorphisms, which showed significant associations with estimated glomerular filtration rate. The primary outcome was new-onset CKD.

RESULTS
During a median follow-up duration of 12.1 years, 9,344 new-onset CKD were documented. Overall, there was a significant inverse association between baseline serum 25OHD and new-onset CKD in participants with diabetes (per SD increment, adjusted hazard ratio [HR] 0.91; 95% CI 0.86–0.96), but not in those without diabetes (per SD increment, adjusted HR 0.98; 95% CI 0.96–1.01; P-interaction between serum 25OHD and diabetes = 0.004). Accordingly, among participants with diabetes, compared with those baseline serum 25OHD &lt;25 nmol/L, a significantly lower risk of new-onset CKD was found in those with 25OHD ≥50 nmol/L (adjusted HR 0.77; 95% CI 0.67–0.89). Moreover, the genetic risk of CKD did not significantly modify the association between baseline serum 25OHD and new-onset CKD among participants with diabetes (P-interaction = 0.127).

CONCLUSIONS
There was an inverse association between baseline serum 25OHD and new-onset CKD in participants with diabetes. The inverse association was not found in participants without diabetes.

Published: September 2022

<p> </p>
<p>Objective: To estimate medical costs associated with 17 major diabetes-related complications and treatment procedures among Medicare beneficiaries aged ≥65 years with type 2 diabetes.</p>
<p>Methods: Data were from the 2006–2017 100% Medicare claims database among beneficiaries enrolled in fee-for-service plans. Records with type 2 diabetes and complications were identified using International Classification of Diseases codes, Ninth Revision and Tenth Revision, and diagnosis-related group codes. The index year was the year when a person was first identified with diabetes with an inpatient claim, or an outpatient claim plus another inpatient/outpatient claim in the 2 years following the first claim in Medicare. Included individuals were followed from index years until death, discontinuation of plan coverage, or December 31, 2017. Fixed-effect regression was used to estimate the cost in years when the complication event occurred and in subsequent years. The total cost for each complication was calculated for 2017 by multiplying the complication prevalence by the cost estimate. All costs were standardized to 2017 U.S. dollars.</p>
<p>Results: Our study included 10,982,900 persons with type 2 diabetes. Follow-up ranged from 3 to 10 years. The three costliest complications were kidney failure treated by transplantation (occurring year $79,045; subsequent years $17,303), kidney failure treated by dialysis ($54,394; $38,670), and lower-extremity amputation ($38,982; $8,084). Congestive heart failure accounted for the largest share (18%) of total complication cost. </p>
<p>Conclusions: Costs associated with diabetes complications were substantial. Our cost estimates provide essential information needed for conducting economic evaluation of treatment/programs to prevent/delay diabetes complications in Medicare beneficiaries. </p>
