Building Sustainable Societies through Purpose-Driven Universities: A Case Study from Ashoka University (India)
Authors: Chakraborty Anirban , Kumar Sumit , Shashidhara L. S. , Taneja Anjali
Published: July 2021

Sustainable Development (SD) is the universal essentiality of present times, and universities have a critical role in implementing this initiative through their functioning, policies and practices. To integrate SD goals, universities should have a global outlook that is still locally rooted in its strategies. In the last decade, various theories and recommendations have been proposed and adopted globally for integrating sustainability in higher education systems. In India, environmental education has been mandated at all formal levels in the education system. Still, there is a strong argument that it is not simply a matter of overhauling syllabi and curricula. Instead, universities should be incorporating SD goals into their research and their own operations. Our study aims to investigate the sustainability model of Ashoka University (India) that approaches its commitment through sustainability-focused courses, research, and operations. This study involves an in-depth literature review and uses an established framework to assess the condition of the university towards sustainability issues. Our case study employed observations, data collections, document reviews, and interactions with different stakeholders. The study concludes that the university is mostly in adherence with the framework at this stage. Critical areas of future development within the framework are proposed considering the global context. This research serves as an entry point for evaluating sustainability issues of the Indian higher education system, and hopes to motivate higher education communities to do further research to improve their sustainability performance and their role as agents of change.
Spatio-Temporal Patterns of Global Population Exposure Risk of PM2.5 from 2000–2016
Authors: Zhao Chengcheng , Pan Jinghu , Zhang Lianglin
Published: July 2021

A high level of fine particulate matter (PM2.5) has become one of the greatest threats to human health. Based on multi-source remote sensing data, the pollutant population exposure model, accompanied by the Theil–Sen Median and Mann–Kendall methods, was used to analyze the spatio-temporal patterns of global population exposure risk of PM2.5 from 2000 to 2016. The population distribution patterns of high-risk exposure areas have been accurately identified; the variation trend and stability of global population exposure risk of PM2.5 have also been analyzed. According to the results, the average concentration of PM2.5 is correlated with the total population. The average concentration of PM2.5 for countries from high to low are Asia (14.7 μg/m3), Africa (8.1 μg/m3), Europe (8.03 μg/m3), South America (5.69 μg/m3), North America (4.41 μg/m3), and Oceania (1.27 μg/m3). In addition, the global average population exposure risk of PM2.5 is decreasing annually. Specifically, China, India, Southeast Asia, and other regions have higher exposure risks. Less developed mountainous regions, cold regions, deserts and tropical rainforest regions have lower exposure risks. Moreover, Oceania, North America, South America and other regions have relatively stable exposure, whereas areas with relatively unstable exposure risk of PM2.5 are mainly concentrated in Asia, India, and eastern China, followed by Southeast Asia, Europe, and Africa. Furthermore, Asia has the largest population of all the continents, followed by Africa and Europe. Countries with increased populations are mainly distributed in Africa, whereas the countries with a declining population are mainly distributed in Europe. Based on this, it is important to identify the relationship between PM2.5 concentration and population exposure risk to improve human settlements and environmental risk assessment.
Exhaust Emissions and Fuel Consumption Analysis on the Example of an Increasing Number of HGVs in the Port City
Authors: Ziemska Monika
Published: July 2021

Due to the increase in cargo handling in ports, and the thereby increase of trucking directly associated with them, this article examines the impact of heavy goods vehicles generated by the port facilities on the environment. The article determines what is feasible to limit the percentage increase in the number of HGVs generated by the port areas such as container terminals or mass, which will result in a significant increase in emissions in the port city. In this study, five intersections were analyzed using micro-simulation to determine exhaust emissions such as CO, NOx, VOC, and fuel consumption. The analysis was made on the example of the port city of Gdynia in Poland, using the actual data. The use of the PTV Vissim tool made it possible to obtain the result data from the simulation of ten variants with a variant representing the current state. The results indicate that increasing the number of HGVs generated by port areas by 40% will make a significant difference in exhaust emissions. The obtained results can be useful for controlling the level of environmental pollution as predictive models.
Relationship between Corporate Sustainability Management and Sustainable Tax Strategies
Authors: Ma Hee Young , Park Sung Jong
Published: July 2021

This study analyzed the relationship between the environmental, social, and governance (ESG) assessment results of the Korea Corporate Governance Service, which evaluates the sustainability management levels of Korean companies and the variability in the five-year cash effective tax rates, a proxy for sustainable tax strategies. Corporate sustainability management allows the continuation of businesses that consider environmental protection, social contribution, and ethical management, as well as short-term financial performance. We expect these companies to prioritize sustainable tax strategies that ensure the long-term maintenance of the tax strategy results. Using a sample of firms listed in the Korean securities market during the 2011–2017 period, we adopted a two-way clustered regression model by a firm and year and established a research model with reference to previous studies and tax strategies. We found a significant negative association between excellent ESG ratings and the variability of cash effective tax rates, as well as between the implementation of ESG assessments and the variability of cash effective tax rates. This result indicates that companies with excellent corporate sustainability management strengthen their sustainable tax strategies and that companies become more interested in sustainable tax strategies after implementing ESG assessments. This study sheds light on the relationship between corporate sustainability management and sustainable tax strategies, helping improve our understanding of the impact of corporate sustainability management on sustainable tax strategies.
Temporal, Spatial, and Socioeconomic Dynamics in Social Media Thematic Emphases during Typhoon Mangkhut
Authors: Zhu Huiyun , Liu Kecheng
Published: July 2021

Disaster-related social media data often consist of several themes, and each theme allows people to understand and communicate from a certain perspective. It is necessary to take into consideration the dynamics of thematic emphases on social media in order to understand the nature of such data and to use them appropriately. This paper proposes a framework to analyze the temporal, spatial, and socioeconomic disparities in thematic emphases on social media during Typhoon Mangkhut. First, the themes were identified through a latent Dirichlet allocation model during Typhoon Mangkhut. Then, we adopted a quantitative method of indexing the themes to represent the dynamics of the thematic emphases. Spearman correlation analyses between the index and eight socioeconomic variables were conducted to identify the socioeconomic disparities in thematic emphases. The main research findings are revealing. From the perspective of time evolution, Theme 1 (general response) and Theme 2 (urban transportation) hold the principal position throughout the disaster. In the early hours of the disaster, Theme 3 (typhoon status and impact) was the most popular theme, but its popularity fell sharply soon after. From the perspective of spatial distribution, people in severely affected areas were more concerned about urban transportation (Theme 2), while people in moderately affected areas were more concerned about typhoon status and impact (Theme 3) and animals and humorous news (Theme 4). The results of the correlation analyses show that there are differences in thematic emphases across disparate socioeconomic groups. Women preferred to post about typhoon status and impact (Theme 3) and animals and humorous news (Theme 4), while people with higher income paid less attention to these two themes during Typhoon Mangkhut. These findings can help government agencies and other stakeholders address public needs effectively and accurately in disaster responses.

Authors: Salehi Mahdi , Zimon Grzegorz
Published: July 2021

The present study evaluates the relationship between intellectual capital and corporate board characteristics on value creation and growth. Different work experiences and education were two indexes of intellectual capital, and gender diversity was the only characteristic of board members. The study’s statistical population includes companies listed on the Tehran Stock Exchange during 2012–2018. Panel data regression models were employed to elucidate the relationship between research variables. The obtained results indicated that the intellectual capital of the board members of companies listed on the Tehran Stock Exchange does not affect companies’ value and growth. According to the results, appointing female managers should not be dependent on firm growth because gender diversity does not affect the value creation and growth of companies listed on the Tehran Stock Exchange.

Authors: Kato Haruka , Matsushita Daisuke
Published: July 2021

The purpose of this study was to identify the walkable streets where traffic behavior changed according to each residential cluster during the COVID-19 pandemic. By elucidating the changes, it is possible to identify streets that should be redesigned following the changes in traffic behavior in relation to human mobility. This study analyzed Ibaraki City, a suburban city located in the Osaka Metropolitan Area. The analysis compared the panel data of the GPS Location History for April 2020 and April 2019. The analysis method used was Empirical Bayesian kriging. The results show that the speed significantly increased in the dense, sprawl, mountain, and old NT clusters. It was also found that the number of cyclists increased during the COVID-19 pandemic. The results suggest a need to design walkable streets according to each residential cluster for the post-COVID-19 pandemic era. For example, some car lanes need to be converted to bike lanes in the main neighborhood to create walkable streets in the clusters.
Corporate Social and Financial Performance: The Role of Firm Life Cycle in Business Groups
Authors: Park Bum-Jin
Published: July 2021

Drawing on agency theory concerning corporate social responsibility (CSR) activities, this study investigates the relationship between corporate social performance (CSP) and corporate financial performance (CFP) at each stage of the firm life cycle (FLC). It also verifies how this relationship is affected by large business groups. This study shows a significant positive relationship between CSP and CFP at the growth and mature stages. This relationship is more pronounced in mature firms than in growth firms. This result indicates that CSR activities increase CFP in the long-term perspective by mitigating the agency problem. Furthermore, at the growth and mature stages, the positive relationship between CSP and CFP changed to be negative in firms of large business groups. This result indicates that the degree to which CSP leads to an increase in CFP is more weakened in large business groups where the agency problem between controlling and other shareholders can be more severe. Finally, this study contributes to prior research by presenting consistent results on the relationship between CSP and CFP using the FLC and large business groups.
Multi-Objective Optimal Power Flow Problems Based on Slime Mould Algorithm
Authors: Khunkitti Sirote , Siritaratiwat Apirat , Premrudeepreechacharn Suttichai
Published: July 2021

Solving the optimal power flow problems (OPF) is an important step in optimally dispatching the generation with the considered objective functions. A single-objective function is inadequate for modern power systems, required high-performance generation, so the problem becomes multi-objective optimal power flow (MOOPF). Although the MOOPF problem has been widely solved by many algorithms, new solutions are still required to obtain better performance of generation. Slime mould algorithm (SMA) is a recently proposed metaheuristic algorithm that has been applied to solve several optimization problems in different fields, except the MOOPF problem, while it outperforms various algorithms. Thus, this paper proposes solving MOOPF problems based on SMA considering cost, emission, and transmission line loss as part of the objective functions in a power system. The IEEE 30-, 57-, and 118-bus systems are used to investigate the performance of the SMA on solving MOOPF problems. The objective values generated by SMA are compared with those of other algorithms in the literature. The simulation results show that SMA provides better solutions than many other algorithms in the literature, and the Pareto fronts presenting multi-objective solutions can be efficiently obtained.

Published: July 2021

This study aims to determine how achievement goals, participation motivation and self-perception levels in physical activity environments relate to the flourishing of young adults. The general purpose of the study was also to examine differences in selected variables of young adults flourishing in physical activity environments. To achieve our aims, the recruited sample consisted of 580 young adult exercisers ranging in age from 18 to 40 years from fitness centers in Izmir, Turkey. Participants completed a personal information form, the Flourishing Scale, the 2 × 2 Achievement Goals Questionnaire for Sport (2 × 2 AGQ-S), the Situational Motivation Scale (SIMS), and the Physical Self-Description Questionnaire (PSDQ). We examined correlations, regressions, and path models with our measured variables. Flourishing relates significantly (p < 0.001) and positively with global self-esteem, the mastery-approach goal, intrinsic motivation, and global physical self-concept. Our path model suggested that the mastery-approach goal, intrinsic motivation, and global self-esteem partially mediated the relationship between global physical self-concept and flourishing. Our findings help to inform alternative approaches for cultivating exercisers’ flourishing. However, knowledge on how to support and develop flourishing is still under-researched in sport and exercise settings.

Published: July 2021

Antibody responses against the influenza A virus hemagglutinin (HA)-protein are studied intensively because they can protect against (re)infection. Previous studies have focused on antibodies targeting the head or stem domains, while other possible specificities are often not taken into account. To study such specificities, we developed a diverse set of HA-domain proteins based on an H1N1pdm2009-like influenza virus strain, including monomeric head and trimeric stem domain, as well as the full HA-trimer. These proteins were used to study the B cell and antibody responses in six healthy human donors. A large proportion of HA-trimer B cells bound exclusively to HA-trimer probe (54–77%), while only 8–18% and 9–23% were able to recognize the stem or head probe, respectively. Monoclonal antibodies (mAbs) were isolated and three of these mAbs, targeting the different domains, were characterized in-depth to confirm the binding profile observed in flow cytometry. The head-directed mAb, targeting an epitope distinct from known head-specific mAbs, showed relatively broad H1N1 neutralization and the stem-directed mAb was able to broadly neutralize diverse H1N1 viruses. Moreover, we identified a trimer-directed mAb that did not compete with known head or stem domain specific mAbs, suggesting that it targets an unknown epitope or conformation of influenza virus’ HA. These observations indicate that the described method can characterize the diverse antibody response to HA and might be able to identify HA-specific B cells and antibodies with previously unknown specificities that could be relevant for vaccine design.
Hydrostatic Densitometer for Monitoring Density in Freshwater to Hypersaline Water Bodies

Published: July 2021

Density, temperature, salinity, and hydraulic head are physical scalars governing the dynamics of aquatic systems. In coastal aquifers, lakes, and oceans, salinity is measured with conductivity sensors, temperature is measured with thermistors, and density is calculated. However, in hypersaline brines, the salinity (and density) cannot be determined by conductivity measurements due to its high ionic strength. Here, we resolve density measurements using a hydrostatic densitometer as a function of an array of pressure sensors and hydrostatic relations. This system was tested in the laboratory and was applied in the Dead Sea and adjacent aquifer. In the field, we measured temporal variations of vertical profiles of density and temperature in two cases, where water density varied vertically from 1.0 × 103 kg·m−3 to 1.24 × 103 kg·m−3: (i) a borehole in the coastal aquifer, and (ii) an offshore buoy in a region with a diluted plume. The density profile in the borehole evolved with time, responding to the lowering of groundwater and lake levels; that in the lake demonstrated the dynamics of water-column stratification under the influence of freshwater discharge and atmospheric forcing. This method allowed, for the first time, continuous monitoring of density profiles in hypersaline bodies, and it captured the dynamics of density and temperature stratification.

Authors: Kromah Varney , Zhang Guanghui
Published: July 2021

Heavy metals pollution of aqueous solutions generates considerable concerns as they adversely impact the environment and health of humans. Among the remediation technologies, adsorption with metal sulfide nanomaterials has proven to be a promising strategy due to their cost-effective, environmentally friendly, surface modulational, and amenable properties. Their excellent adsorption characteristics are attributed to the inherently exposed sulfur atoms that interact with heavy metals through various processes. This work presents a comprehensive overview of the sequestration of heavy metals from water using metal sulfide nanomaterials. The common methods of synthesis, the structures, and the supports for metal sulfide nano-adsorbents are accentuated. The adsorption mechanisms and governing conditions and parameters are stressed. Practical heavy metal remediation application in aqueous media using metal sulfide nanomaterials is highlighted, and the existing research gaps are underscored.

Forecasts of the scenarios for the development of the world nuclear power industry are given, taking into account the limited resources of natural uranium and the concept of sustainable development. On the basis of a new model of dynamic forecasting of the depletion of fossil resources, possible restrictions on the development of hydrocarbon and nuclear energy at thermal reactors are considered. It is shown that the existing nuclear power based on thermal reactors does not have a long-term perspective (more than 100 years) for a number of reasons. The most promising development in order to maintain and, moreover, increase the contribution of nuclear power plants to electricity generation, is the two-component nuclear power system with a combined uranium-plutonium nuclear fuel cycle. However, the widespread introduction of fast-neutron reactors is possible in the second half of this century. For the next few decades, the tasks of economic substantiation of the diversification of business product lines in the field of a closed nuclear fuel cycle for scenarios of the development of nuclear power on thermal reactors in conditions of limited traditional reserves of natural uranium are urgent

Investigation of deformed wing virus, black queen cell virus, and acute bee paralysis virus infections in honey bees using reverse transcriptase-polymerase chain reaction (RT-PCR) method
Authors: USTA Ayşegül , YILDIRIM Yakup
Published: July 2021

Viruses are one of the most potential risk factors that negatively affect the different life stages of honey bees. This study was conducted to determine the presence of infections caused by the deformed wing virus (DWV), black queen cell virus (BQCV), and acute bee paralysis virus (ABPV) in honey bees in the beekeeping regions of Burdur, along with obtaining information about their prevalence in this particular region. In our study, the adult bees were taken from 31 different beehives and comb samples that had different honey bee breeds and were sampled randomly from 15 beekeeping areas within the region. The collected samples were analyzed using the reverse transcriptase-polymerase chain reaction (RT-PCR), and the prevalence of DWV, BQCV, and ABPV infections were determined to be 74.19% (23/31), 25.81%, (8/31) and 74.19% (23/31), respectively. In this study, the distribution of positive samples and the rates of multiple infections were determined in the colonies. Of the positive honey bee samples, 12 (%38.71) were detected only for one virus, 9 (%29.03) were positive for two viruses (DWV-ABPV) and 8 (%25.81) were positive for all three viruses. In the present study, the presence of the three bee viruses that caused significant damage to the colonies by multiple infections in the Burdur region was determined with RT-PCR. To our knowledge, this is the first report of three mentioned bee infections in honey bees in the Burdur region. The revealed epidemiological conditions lead to the conclusion that serious measures are needed to control these infections in this region.
Perbandingan Nilai Hazard Kejadian Tsunami di Indonesia Berdasarkan Posisi Garis Khatulistiwa (Katalog Tsunami Indonesia 1802 - 2018)
Authors: Anwar Samsul
Published: July 2021

ABSTRAKIndonesia merupakan salah satu negara yang rawan terjadinya tsunami. Berdasarkan Katalog Tsunami BMKG, sepanjang tahun 1802 hingga 2018 telah terjadi 219 tsunami di Indonesia. Dengan mempelajari kejadian tsunami pada masa lalu berarti merupakan salah satu langkah mitigasi bencana dalam upaya meminimalisir kerugian yang disebabkan oleh tsunami pada masa yang akan datang. Tujuan penelitian ini adalah menghitung nilai hazard rasio kejadian tsunami berdasarkan lokasi kejadiannya relatif terhadap garis khatulistiwa. Model Cox Proportional Hazard (Cox PH) menunjukkan bahwa tsunami di wilayah selatan garis khatulistiwa cenderung 50,5% lebih cepat terjadi dibandingkan dengan wilayah utara. Hal ini disebabkan karena wilayah selatan berpotensi lebih besar akan terjadinya kejadian tsunamigenik termasuk gempa bumi, erupsi gunungapi dan penyebab lainnya dari pada wilayah utara. Adanya zona subduksi aktif akibat pertemuan lempeng tektonik Indo-Australia dan Eurasia di wilayah selatan meningkatkan potensi terjadinya tsunamigenik di wilayah tersebut. Penelitian lebih lanjut diperlukan untuk menjelaskan hubungan antara garis khatulistiwa dengan kejadian tsunamigenik di Indonesia.Kata kunci: garis khatulistiwa, hazard rasio, Indonesia, model cox ph, tsunami, tsunamigenikABSTRACTIndonesia is a tsunami-prone country. Based on the BMKG Tsunami Catalog, from 1802 to 2018 there were 219 tsunamis in Indonesia. By studying tsunami events in the past means one disaster mitigation measure in an effort to minimize losses caused by tsunamis in the future. The objective of the study is to measure the tsunami hazard ratio based on its location relative to the equator position. Cox Proportional Hazard Model (Cox PH) showed that tsunamis in the southern area tended to happen 50.5% faster compared to the northern area. This is because the southern region has greater potential for tsunamigenic events including earthquakes, volcanic eruptions, and other causes than the northern region. The existence of an active subduction zone due to the confluence of Indo-Australian and Eurasian tectonic plates in the southern region increases the potential for tsunamigenic events in the region. Further research is necessarily needed to explain the relationship between the equator and tsunamigenic events in Indonesia.Keywords: equator, hazard ratio, Indonesia, cox ph model, tsunami, tsunamigenic

Authors: Sadiq Obanishola. M. , Salau Ayotomiwa O.
Published: July 2021

This research is based on the study of the deflection response of a structural circular sandwich plate, simply supported or clamped at its boundary, under different loading configurations (uniformly distributed, concentrated, and linearly varying load). The non-linear governing differential equation of the plate was solved using an Analytical method, Variational Iteration Method (VIM), after which the Finite Element Method (FEM) was used to validate its accuracy. Results showed a significantly higher deflection value for the simply supported plate compared to the clamped plate for all the various loading configurations, where a sandwich plate of radius 100mm under clamped conditions generated deflection of 0.05mm when exposed to a uniform load while a deflection of 0.25mm for simply supported condition. The concentrated load was also discovered to have a major effect on the body of the sandwich plate as it was seen to generate the highest deflection among all loading configurations regardless of its boundary conditions where a simply supported condition with a point load had a high deflection amounting to 2.1mm.

Code requirements are usually fulfilled during the design of a building. On the other hand, reinforced concrete (RC) frames (particularly in the developing regions of the world) are found deficient due to unregulated constructions. Majority of such deficient structures lack shear reinforcement in beam-column joints. Collapse of these deficient buildings (as a result of limited ductility) triggered many socio-economic and human losses which is evident from recent earthquake disasters. This paper presents an experimental study which was conducted on a 1:4 reduced scale three-storey RC special moment resisting frame (SMRF) lacking shear reinforcement in the beam-column joints. The lack of confinement bars causes shear hinging of joints that reduces the displacement ductility of the frame. Shake-table tests were conducted on test model that was subjected to acceleration time history of 1994 Northridge earthquake, having a peak ground acceleration of 0.57g. The acceleration was linearly scaled to multiple levels and to sinusoidal base excitations of various frequencies and displacements. Moderate to severe damage at each storey level was observed in the joint panels due to the lack of lateral reinforcing ties in the joints. The data obtained from shake table tests were processed and analysed to develop a lateral force-deformation capacity curve, which was bi-linearized as an elasto-plastic curve to compute various response parameters of frame. The ductility factor (RÎ¼) of the tested model was found to be equal to 1.95, which is thirty-five percent less than the code recommended value of RÎ¼ for RC SMRF structures.
Los microbios interpelan a las terapias

El covid-19 ha sido la causa inmediata de la más profunda crisis de la sociedad moderna. Este artículo trata de un aspecto de esta crisis: el papel de la medicina capitalista hegemónica. El enfoque no es técnico sino social; no se refiere a la eficacia del diagnóstico o sus medicamentos, sino a la trayectoria teórica y metodológica de largo alcance. El objetivo es llamar la atención sobre cómo la medicina capitalista hegemónica ha roto radicalmente con las tradiciones médicas precapitalistas, sin considerar oportunidades en ciencia y tecnología que podrían resultar más eficientes para atender la salud de la población, pero desechadas por seleccionar un camino más rentable para la industria farmacéutica.
El rey va desnudo: realidad y retórica en el proyecto transformista de la 4T
Authors:   Universidad Autónoma de Zacatecas, Márquez Covarrubias Humberto
Published: July 2021

En México, el gobierno de la «cuarta transformación» habla profusamente de neoliberalismo, pero no de capitalismo; de corrupción, pero no de explotación; de megaproyectos, pero no de extractivismo; de democracia, pero no de oligarquía; de inseguridad, pero no de despojo. La tentativa de cambio derivada del triunfo electoral de amlo abre el debate nacional sobre un desarrollo alternativo —incluso de alternativas al desarrollo. No obstante, la agenda política del obradorismo está hegemonizando los términos de discusión, encubriendo los problemas estructurales de México y reduciendo el enfoque al tema de corrupción y austeridad, dos perspectivas que no son contrarias a la estructura de poder que se dice contravenir. En sus primeros movimientos, el proyecto de gobierno de la «cuarta transformación» se orienta a una concentración del poder político mediante la reconstrucción del presidencialismo y la reestructuración burocrática, para luego incidir en la reproducción del capital mediante la continuidad de políticas macroeconómicas neoliberales y la ejecución de proyectos energéticos y de infraestructura con el concurso del gran capital. Además de afianzar una base social de apoyo con programas asistencialistas neopopulistas, piedra angular del discurso político. No obstante, se vislumbra un proceso fáustico que en sus propósitos anticipa una transformación de la vida nacional que está atrapada en proceso de modernización capitalista plagado de contradicciones, tensiones sociales y una crisis multidimensional económica, sanitaria y de seguridad. La expectativa de una transformación social sustantiva amerita, inevitablemente, afinar y profundizar el debate teórico y político sobre los grandes problemas nacionales y sus alternativas en un contexto global intrincado.

Fenomena K-Pop di Arab Saudi
Authors: Mariani Ani
Published: July 2021

Arab Saudi sering dipandang sebagai negara yang sangat konservatif karena kuatnya pengaruh ideologi Wahabisme dalam pemerintahan, sebuah ideologi yang cenderung dipersepsikan sebagai paham yang anti modernitas. Peran ulama juga selama ini dinilai sangat kuat dalam menentukan kebijakan negara. Akan tetapi, sejak tahun 2016, terjadi perubahan sosial yang besar berupa kebebasan dan kelonggaran yang diberikan negara di berbagai sektor, terutama di sektor sosial, di antaranya: perempuan diperbolehkan memasuki stadion olahraga, menyetir, bepergian tanpa wali. Perubahan ini termasuk pula memberi kelonggaran hiburan seperti konser musik, termasuk yang cukup mengejutkan adalah masuknya fenomena K-Pop di Saudi. Kebijakan ini menciptakan perdebatan di antara berbagai kelompok, terutama di kalangan para ulama Wahhabi. Artikel ini bertujuan untuk menganalisis dampak yang muncul dari proses reformasi sosial di Arab Saudi terhadap otoritas keagamaan di negara tersebut. Penelitian ini menggunakan metode kualitatif dengan melakukan studi literatur. Teori yang digunakan untuk menganalisis adalah teori otoritas keagamaan dan kaitannya dengan komunikasi digital yang dikemukakan oleh Cheong (2011). Hasil penelitian menunjukkan bahwa reformasi sosial di Arab Saudi memengaruhi dinamika otoritas keagamaan dan terjadi pergeseran otoritas dari otoritas tradisional, seperti ulama, menjadi otoritas sipil.
