Effect of Cadmium Chloride and Cadmium Nitrate on Growth and Mineral Nutrient Content in the Root of Fava Bean (Vicia faba L.)
Authors: Piršelová Beáta , Ondrušková Emília
Published: May 2021

The present study aimed to analyze the differences in the tolerance of fava bean (Vicia faba cv. Aštar) roots to cadmium in nitrate—Cd(NO3)2—and chloride—CdCl2—solutions. The physiological and biochemical parameters were assessed. The tested doses of Cd (50, 100, 150 and 300 mg/L) did not influence the germination of seeds. However, considerable growth inhibition and dehydration were observed after 96 h incubation. The thickness of roots and rupture of cell membranes increased along with the increasing concentration of the metal in the solution. At a Cd dose of 300 mg/L, irrespective of the solution used, increased nitrogen concentration and no change in sodium content were observed. The content of magnesium increased due to the dose of 100 mg/L (cadmium nitrate) and the content of calcium increased due to the dose of 300 mg/L (in either nitrate or chloride). The correlation analyses pointed to a possible effect of nitrates in the applied solutions on the accumulation of Cd and some minerals in the roots of the given variety of fava bean. This may be important for both research and agricultural practice. The identification of crops with high tolerance to cadmium, as well as knowledge about the mechanisms of ion interactions at the soil solution–plant level, is important in terms of such crops’ use in the process of the remediation of cadmium-contaminated soils coupled with food production.

Published: May 2021

A highly efficient reduction process of Cr (VI) with biochar was conducted in this paper. The results showed that nearly 100% Cr (VI) was reduced at selected reaction conditions: Dosage of biochar at m (C)/m(Cr) = 3.0, reaction temperature of 90 °C, reaction time of60 min, and concentration of H2SO4 of 20 g/L. The reduction kinetics analysis demonstrated that the reduction of Cr (VI) fitted well with the pseudo-first-order model and the apparent activation energy was calculated to be 40.24 kJ/mol. Response surface methodology confirmed that all of the experimental parameters had a positive effect on the reduction of Cr (VI). The influence of each parameter on the reduction process followed the order: Dosage of biochar>concentration of H2SO4>reaction temperature >reaction time. This paper provides a versatile strategy for the treatment of wastewater containing Cr (VI) and shows a bright tomorrow for wastewater treatment.
Impact of Fintech on Bank Risk-Taking: Evidence from China
Authors: Deng Liurui , Lv Yongbin , Liu Ye , Zhao Yiwen
Published: May 2021

This article focuses on the relationship between Fintech and bank risk-taking behavior. Since Robo-Advisor is one of the mature applications of Fintech, we found that the development of Fintech will have a greater impact on small and medium-sized banks through the establishment of a Robo-Advisor model. This paper uses a benchmark regression model to analyze the municipal digital financial inclusion index compiled by Peking University and the annual report data of 155 small and medium-sized banks from 2011 to 2016. We found that the development of Fintech has significantly reduced bank risk-taking level. This result is still valid after the robustness test of replacing the bank’s risk-taking index and replacing the Fintech development index. We used the urban innovation index as an instrumental variable to deal with the endogenous problem, and obtained consistent estimation results. The test of the intermediary effect shows that the development of Fintech will affect the bank risk-taking through channels such as the bank’s internal interest margin, management capabilities, the bank’s external competition intensity, and residents’ saving willingness. Heterogeneity analysis shows the reduction effect of Fintech on bank risk-taking is more pronounced in banks in eastern and western regions in China, the large banks and the urban commercial banks.
Study of a Controlled Piezoelectric Damper
Authors: Makowski Michał , Knap Lech
Published: May 2021

In this work an original construction of a vibration damper controlled by means of a valve with a short time of operation lag is presented. The valve-controlling properties of the damper regulates the flow of fluid between the chambers of the damper and was constructed using piezoelectric actuators, whose characteristic feature is the possibility to change dimensions, e.g., length, under the influence of voltage. As a result, by changing voltage it is possible to control the throttle of the flow by changing the width of a gap, which influences a change of damping forces. Such a solution enables a quicker change of damping forces than in other kinds of controlled damper. Due to the obtained properties, the damper may be applied to reduce the vibrations of vehicles and machines that undergo quick-change loads. In the article, the results of experimental studies of the aforementioned damper are presented. Based on the results, dissipative characteristics were determined. Also, results of numerical studies comprising the development of a numerical model of a controlled piezoelectric damper are shown. Results of numerical studies, as well as experimental studies, are presented in the form of dissipative characteristics. Comparison of results of numerical and experimental studies confirms the possibility to apply this kind of construction in semi-active systems of vibration reduction of vehicles and machines.
HAGP: A Heuristic Algorithm Based on Greedy Policy for Task Offloading with Reliability of MDs in MEC of the Industrial Internet
Authors: Guo Min , Huang Xing , Wang Wei , Liang Bing , Yang Yanbing , Zhang Lei , Chen Liangyin
Published: May 2021

In the Industrial Internet, computing- and power-limited mobile devices (MDs) in the production process can hardly support the computation-intensive or time-sensitive applications. As a new computing paradigm, mobile edge computing (MEC) can almost meet the requirements of latency and calculation by handling tasks approximately close to MDs. However, the limited battery capacity of MDs causes unreliable task offloading in MEC, which will increase the system overhead and reduce the economic efficiency of manufacturing in actual production. To make the offloading scheme adaptive to that uncertain mobile environment, this paper considers the reliability of MDs, which is defined as residual energy after completing a computation task. In more detail, we first investigate the task offloading in MEC and also consider reliability as an important criterion. To optimize the system overhead caused by task offloading, we then construct the mathematical models for two different computing modes, namely, local computing and remote computing, and formulate task offloading as a mixed integer non-linear programming (MINLP) problem. To effectively solve the optimization problem, we further propose a heuristic algorithm based on greedy policy (HAGP). The algorithm achieves the optimal CPU cycle frequency for local computing and the optimal transmission power for remote computing by alternating optimization (AP) methods. It then makes the optimal offloading decision for each MD with a minimal system overhead in both of these two modes by the greedy policy under the limited wireless channels constraint. Finally, multiple experiments are simulated to verify the advantages of HAGP, and the results strongly confirm that the considered task offloading reliability of MDs can reduce the system overhead and further save energy consumption to prolong the life of the battery and support more computation tasks.
Regulatory and Technical Constraints: An Overview of the Technical Possibilities and Regulatory Limitations of Vehicle Telematic Data
Authors: McDonnell Kevin , Murphy Finbarr , Sheehan Barry , Masello Leandro , Castignani German , Ryan Cian
Published: May 2021

A telematics device is a vehicle instrument that comes preinstalled by the vehicle manufacturer or can be added later. The device records information about driving behavior, including speed, acceleration, and turning force. When connected to vehicle computers, the device can also provide additional information regarding the mechanical usage and condition of the vehicle. All of this information can be transmitted to a central database via mobile networks. The information provided has led to new services such as Usage Based Insurance (UBI). A range of consultants, industry commentators and academics have produced an abundance of projections on how telematics information will allow the introduction of services from personalized insurance, bespoke entertainment and advertise and vehicle energy optimization, particularly for Electric Vehicles (EVs). In this paper we examine these potential services against a backdrop of nascent regulatory limitations and against the technical capacity of the devices. Using a case study approach, we examine three applications that can use telematics information. We find that the expectations of service providers will be significantly tempered by regulatory and technical hurdles. In our discussion we detail these limitations and suggest a more realistic rollout of ancillary services.
Return Period Evaluation of the Largest Possible Earthquake Magnitudes in Mainland China Based on Extreme Value Theory
Authors: Ma Ning , Bai Yanbing , Meng Shengwang
Published: May 2021

The largest possible earthquake magnitude based on geographical characteristics for a selected return period is required in earthquake engineering, disaster management, and insurance. Ground-based observations combined with statistical analyses may offer new insights into earthquake prediction. In this study, to investigate the seismic characteristics of different geographical regions in detail, clustering was used to provide earthquake zoning for Mainland China based on the geographical features of earthquake events. In combination with geospatial methods, statistical extreme value models and the right-truncated Gutenberg–Richter model were used to analyze the earthquake magnitudes of Mainland China under both clustering and non-clustering. The results demonstrate that the right-truncated peaks-over-threshold model is the relatively optimal statistical model compared with classical extreme value theory models, the estimated return level of which is very close to that of the geographical-based right-truncated Gutenberg–Richter model. Such statistical models can provide a quantitative analysis of the probability of future earthquake risks in China, and geographical information can be integrated to locate the earthquake risk accurately.
Equity/Equality, Diversity, and Inclusion (EDI) in Universities: The Case of Disabled People
Authors: Wolbring Gregor , Lillywhite Aspen
Published: May 2021

The origin of equity/equality, diversity, and inclusion (EDI) initiatives at universities are rooted in the 2005 Athena SWAN (Scientific Women’s Academic Network) charter from Advance HE in the UK, which has the purpose of initiating actions that generate gender equality in UK universities. Since then, Advance HE also set up a “race charter” to deal with equality issues that are experienced by ethnic staff and students within higher education. Today “equality, diversity and inclusion” and “equity, diversity and inclusion” (from now on both called EDI) are used as phrases by universities in many countries to highlight ongoing efforts to rectify the problems that are linked to EDI of students, non-academic staff, and academic staff, whereby the focus broadened from gender to include other underrepresented groups, including disabled students, disabled non-academic staff, and disabled academic staff. How EDI efforts are operationalized impacts the success and utility of EDI efforts for disabled students, non-academic staff, and academic staff, and impacts the social situation of disabled people in general. As such, we analysed in a first step using a scoping review approach, how disabled students, non-academic staff, and academic staff are engaged with in the EDI focused academic literature. Little engagement (16 sources, some only abstracts, some abstracts, and full text) with disabled students, non-academic staff, and academic staff was found. This bodes ill for the utility of existing EDI efforts for disabled students, non-academic staff, and academic staff, but also suggests an opening for many fields to critically analyse EDI efforts in relation to disabled students, non-academic staff, and academic staff, the intersectionality of disabled people with other EDI groups and the impact of the EDI efforts on the social situation of disabled people beyond educational settings. The problematic findings are discussed through the lens of ability studies and EDI premises, as evident in EDI policy documents, EDI academic, and non-academic literature covering non-disability groups, and policy documents, such as the 2017 “UNESCO Recommendation on Science and Scientific Researchers” and the 1999 “UNESCO World Conference on Sciences” recommendations that engage with the situation of researchers and research in universities.
Unsupervised Feature Selection for Histogram-Valued Symbolic Data Using Hierarchical Conceptual Clustering
Authors: Ichino Manabu , Umbleja Kadri , Yaguchi Hiroyuki
Published: May 2021

This paper presents an unsupervised feature selection method for multi-dimensional histogram-valued data. We define a multi-role measure, called the compactness, based on the concept size of given objects and/or clusters described using a fixed number of equal probability bin-rectangles. In each step of clustering, we agglomerate objects and/or clusters so as to minimize the compactness for the generated cluster. This means that the compactness plays the role of a similarity measure between objects and/or clusters to be merged. Minimizing the compactness is equivalent to maximizing the dis-similarity of the generated cluster, i.e., concept, against the whole concept in each step. In this sense, the compactness plays the role of cluster quality. We also show that the average compactness of each feature with respect to objects and/or clusters in several clustering steps is useful as a feature effectiveness criterion. Features having small average compactness are mutually covariate and are able to detect a geometrically thin structure embedded in the given multi-dimensional histogram-valued data. We obtain thorough understandings of the given data via visualization using dendrograms and scatter diagrams with respect to the selected informative features. We illustrate the effectiveness of the proposed method by using an artificial data set and real histogram-valued data sets.
Increased PACAP- and DβH-Positive Hepatic Nerve Fibers after Bisphenol A Exposure
Authors: Thoene Michael , Rytel Liliana , Dzika Ewa , Wojtkiewicz Joanna
Published: May 2021

Bisphenol A (BPA) is an endocrine-disrupting compound (EDC) that can be found nearly everywhere in our polluted world. BPA has been correlated with pathophysiologies that include psychological disorders, especially in children. This study used juvenile porcine models to investigate the effects of BPA on the liver of developing vertebrates in order to determine the effects of BPA on innervated hepatic samples with the use of double-labeled immunofluorescence. This study specifically investigated the sympathetic nervous system (SNS) colocalized with a specific neural marker (PACAP) that has previously been correlated with specific pathophysiologies in the literature. In the liver, it was observed that there were significantly increased nerve fibers in the SNS colocalized with the neural marker PACAP after exposure to BPA at concentrations considered to be “safe” with the same or more profound effects at higher exposure levels. The implications of childhood exposure to BPA are then discussed with regard to several correlation studies that have linked BPA exposure to behavioral/psychological disorders. It is possible that BPA exposure in childhood may upregulate the SNS and PACAP levels, thereby contributing to the correlations in the literature.

Published: May 2021

Wound infections with drug-resistant bacteria lead to higher mortality and morbidity and increased healthcare costs. We aimed to describe the spectrum of bacterial pathogens, isolated from wound cultures in Yangon General Hospital in 2018, and their antimicrobial resistance (AMR) patterns and to understand the challenges in implementing an AMR surveillance system in Myanmar. We conducted a concurrent mixed-methods study involving analysis of surveillance data and in-depth interviews with nine key personnel involved in AMR surveillance. Of 1418 wound specimens processed, 822 (58%) were culture-positive. The most common Gram-positive bacteria were coagulase-negative staphylococci (23.3%) and Staphylococcus aureus (15.1%). Among Gram-negative bacteria, Escherichia coli (12.5%) and Pseudomonas aeruginosa (10.1%) were common. Staphylococcus aureus isolates were resistant to penicillin (98%), oxacillin (70%) and tetracycline (66%). Escherichia coli showed resistance to ampicillin (98%). Lack of dedicated and trained staff (microbiologist, technician, data entry operator), lack of computers at sentinel sites and non-uniform and non-standardized data capture formats were the major challenges in implementing AMR surveillance. These challenges need to be addressed urgently. We also recommend periodic analysis and sharing of antibiograms at every hospital to inform the treatment regimens used in wound management.
Dynamical Analysis of Charged Dissipative Cylindrical Collapse in Energy-Momentum Squared Gravity
Authors: Gul Muhammad , Sharif Muhammad
Published: May 2021

This paper investigates the dynamics of charged cylindrical collapse with the dissipative matter configuration in f(R,TαβTαβ) theory. This newly formulated theory resolves the primordial singularity and provides feasible cosmological results in the early universe.Moreover, its implications occur in high curvature regime where the deviations of energy-momentum squared gravity from general relativity is confirmed. We establish dynamical and transport equations through the Misner–Sharp and Mu¨ler–Israel Stewart techniques, respectively. We then couple these equations to examine the impact of effective fluid parameters and correction terms on the collapsing phenomenon. A connection between the modified terms, matter parameters, and Weyl tensor is also developed. To obtain conformal flatness, we choose a particular model of this theory and assume that dust matter with zero charge leads to conformal flatness and homogenous energy density. We found that the modified terms, dissipative matter, and electromagnetic field reduce the collapsing phenomenon.
Delivering routine immunisations in London during the COVID-19 pandemic: lessons for future vaccine delivery. A mixed-methods study
Authors: Skirrow Helen , Flynn Charlotte , Heller Abigail , Heffernan Catherine , Mounier-Jack Sandra , Chantler Tracey
Published: May 2021

Background

General practices in England have continued to care for patients throughout the COVID-19 pandemic by instigating major changes to service delivery. Immunisations have continued, although the number of vaccines delivered initially dropped in April 2020.

Aim

To evaluate how COVID-19 impacted the delivery of immunisations in London and identify innovative practices to inform future delivery, including for COVID-19 vaccines.

Design & setting

A mixed-methods study of immunisation delivery in London, UK.

Method

An online survey of London general practices was undertaken in May 2020 to produce a descriptive analysis of childhood immunisation delivery and identify innovative delivery models. Semi-structured interviews were conducted between August and November 2020 to explore innovative immunisation models, which were analysed thematically.

Results

Sixty-eight per cent (n = 830) of London practices completed the survey and 97% reported having continued childhood immunisation delivery. Common delivery adaptations included spaced-out appointments, calling parents beforehand, and having only one parent attend. Forty-three practices were identified as having innovative models, such as delivering immunisations outside practice buildings or offering drive-through services. The thematic analysis of 14 semi-structured interviews found that, alongside adaptations to immunisation delivery within practices, existing local networks collaborated to establish new immunisation delivery models. Local population characteristics affected delivery and provide insights for large-scale vaccine deployment.

Conclusion

Immunisations continued during 2020 with practices adapting existing services. New delivery models were developed by building on existing local knowledge, experiences, and networks. Immunisation delivery during the pandemic, including for COVID-19 vaccines, should be tailored to local population needs by building on primary care immunisation expertise.
EVALUATION OF THE POSSIBILITY OF USING REFTINSKAYA GRES ASH IN THE PRODUCTION OF CONTINUOUS GLASS FIBER
Authors: Onischuk V. , Lazarova Y. , Evtushenko E.
Published: May 2021

The article presents the results of the evaluation of the study of the possibility of using ash and slag waste (ash) of Reftinskaya GRES as a component of the charge used in the production of continuous glass fiber of high-modulus (type E), dielectric resistant (type S) and high-strength, chemically stable basalt (type B) compositions. Since the chemical composition of ash is multicomponent and significantly differs from the compositions of raw materials traditionally used in the production of glass fiber, in order to establish the technological features of its use as a component of the charge, experimental compositions of glasses were designed to achieve their specified physical and mechanical properties, with the maximum possible content of ash in the composition of glass charges. A priori assessment showed that acceptable properties of glass for glass fiber compositions E, S and B can be obtained at the content of 36%, 68% and 64% ash in the charges, respectively, for the listed types of glass. The determination of the glass transition temperature intervals of the experimental charge compositions showed that an increase in the ash content in them increases the temperature that ensures the production of a high-quality melt. Studies of the tendency of experimental glass compositions to crystallization, which prevents the effective process of fiber formation, allowed us to determine that almost all compositions have a reduced tendency to crystallization, therefore, they can be used in the production of glass fibers of types S, E and B.
Retrospectiva del Estado y las políticas de niñez.

Published: May 2021

de niñez se analizan los giros en la agenda política local entre los años ochenta y los

noventa. En el retorno a la democracia, la primera infancia parecía ubicarse entre las

prioridades de dicha agenda, pero luego fue relegada. En contraste, los “chicos de/en

la calle” emergieron como un problema más urgente y visible que permitía confrontar

con las políticas de institucionalización–emblemáticas del modelo tutelar–. También

por esos años surgieron programas “alternativos” al asistencialismo y a dicho modelo

que combinaban proyectos socioeducativos y redes territoriales de sostén ante situa ciones críticas. El artículo recupera (y se escribe desde el nivel de) la implementación

de esas experiencias –diversas en sus modalidades, pero con algunas características

compartidas en cuanto al encuadre y abordaje– que suelen quedar opacadas por la

confrontación dicotómica entre dos modelos (el tutelar y el enfoque de derechos) que

apuntaló la agenda de aquel período hacia una disputa normativa.

Midyat 19. yüzyılın sonlarına kadar Yakubi/Süryani Hristiyanların çoğunlukta olduğu ve Turabdin olarak tanımlanan bölgenin merkezidir. Bölgede Müslüman, Hristiyan ve Yezidiler, Süryanice, Kürtçe, Arapça (Mahallemi) ve Ermenice konuşarak farklı din ve etnik kimlikleriyle günlük yaşamın olağan seyri içinde çapraz ilişki ağları geliştirdiler. Midyat ve çevresinde Müslümanlar ve Hristiyanlar dil, mezhep ve aşiret gibi farklı ve kısmen nisbi kimlikler üzerinden çatışma ve ittifak alanları oluşturdular. Ancak “Çok Kimlikli Toplumlarda İhtida/İrtidat Hareketleri ve Kadınların “Öteki” ile Evliliği: Midyat Örneği” adı verilen bu çalışmada da görüleceği gibi, tüm bu varsayımsal kimlikler kadınların din değiştirerek evliliği söz konusu olduğunda terkedilerek, kitleleri bir din veya mezhep etrafında toplayabilmektedir. Bu çalışmada, Tanzimat’la beraber kaza merkezi olan Midyat’ın toplumsal yapısı bağlamında ihtida ve kadınların din değiştirerek yaptıkları evliliklerin ilişkilere etkisi incelenecektir. Makalede çok kimlikli toplumsal ilişkilerde din değiştirme ve kadınların “öteki” ile evlilikleri cemaatin namusuna doğrudan bir saldırı olarak algılandığı, simgesel zafer ya da yenilgi olarak değerlendirildiği, cemaatler arası dinî çatışma ve ittifaklara dönüştüğü Midyat özelinde iddia edilmektedir.

The modern period of socioeconomic development in Latin America determines the need for a significant improvement in the quality of training. On the one hand, this is due to scientific and technological progress, the consequences of which are manifested in almost all areas of people's professional and social activity, including the educational field, on the other hand, with comprehensive research that ensures the creation, application and dissemination of knowledge in the social field. Economic space where innovation becomes a systemic phenomenon. Of great importance is the fact that scientific and technological progress not only poses new requirements for the person himself, but also for the higher professional education system. The contradiction that has arisen between the increasing volume of information and the crisis in the didactic methods of training specialists requires a transition towards fundamentally new technologies of vocational training. The need to change the priorities of professional training in the direction of the development of heuristic and creative thinking, the formation of the individual as a subject of self-development, the mastery of the tools for the management of their own educational activities is increasingly evident. An increase in the applied component of training, a change in the emphasis on the independence of educational work, a certain state in educational standards, allows to form a system of generalized knowledge, skills and abilities that can be transferred from one area to another and act as an integral basis for professional development, highlighting specialized professional skills that are capable of responding adequately to ongoing changes, making decisions independently and putting them into practice in the process of mastering new technologies and professions.
Defining and Measuring Completion and Assessment Biases with Respect to English Language and Development Status: Not All MOOCs are Equal

The emergence of Massive Open Online Courses (MOOCs) broadened the educational landscape by providing free access to quality learning materials for anyone with a device connected to the Internet. However, open access does not guarantee equals opportunities to learn, and research has repetitively reported that learners from affluent countries benefit the most from MOOCs. In this work, we delve into this gap by defining and measuring completion and assessment biases with respect to learners' language and development status. We do so by performing a large-scale analysis across 158 MITx MOOC runs from 120 different courses offered on edX between 2013 and 2018, with 2.8 million enrollments. We see that learners from developing countries are less likely to complete MOOCs successfully, but we do not find evidence regarding a negative effect of not being English-native. Our findings point out that not only the specific population of learners is responsible for this bias, but also that the course itself has a similar impact. Independent of and less frequent than completion bias, we found assessment bias, that is when the mean ability gained by learners from developing countries is lower than that of learners from developed countries. The ability is inferred from the responses of the learners to the course-assessment using Item Response Theory (IRT).Finally, we applied Differential Item Functioning (DIF) methods with the objective of detecting items that might be causing the assessment bias, obtaining weak, yet positive results with respect to the magnitude of the bias reduction. Our results provide statistical evidence on the role that course design might have on these biases, with a call for action so that the future generation of MOOCs focus on strengthening their inclusive design approaches.
Ummah’s Rights or Human Rights? Universalism, Individualism, and Islamic Ethics in the Twenty-first Century
Authors: Frick Marie-Luisa
Published: May 2021

Against the background of the trend of Islamizing human rights on the one hand, as well as increasing skepticism about the compatibility of Islam and human rights on the other, I intend to analyze the potential of Islamic ethics to meet the requirements for vitalizing the idea of human rights. I will argue that the compatibility of Islam and human rights cannot be determined merely on the basis of comparing the specific content of the Islamic moral code(s) with the rights stipulated in the International Bill of Rights, but by scanning (different conceptions of) Islamic ethics for the two indispensable formal prerequisites of any human rights conception: the principle of universalism (i.e., normative equality) and individualism (i.e., the individual enjoyment of rights). In contrast to many contemporary (political) attempts to reconcile Islam and human rights due to urgent (global) societal needs, this contribution is solely committed to philosophical reasoning. Its guiding questions are “What are the conditions for deriving both universalism and individualism from Islamic ethics?” and “What axiological axioms have to be faded out or reorganized hierarchically in return?”
Strategies for Enhancing the Understanding of Islam in the Media
Authors: Yousif Ahmad F.
Published: May 2021

During the last two decades, the world witnessed a meteoric rise in the role played by the media in influencing human perceptions of other people, places, and things. This tremendous influence has had both beneficial and detrimental consequences for individuals and communities across the globe. Muslims have experienced firsthand the harmful impact of the media and its ability to negatively influence public opinion. How has such a state of affairs come about? Why is Islam so misunderstood in the global media, and more importantly, how can this situation be remedied? This paper will examine some of the reasons for the media’s misunderstanding of Islam, first in the Western world and second in the Muslim world. Subsequently, it will propose various strategies for enhancing the Western and Muslim media’s understanding of Islam.
Sufism, Politics, and the Arab Spring
Authors: Muedini Fait
Published: May 2021

This paper examines the role of Sufi individuals and groups in the politics of the Middle East and North Africa during and following the Arab Spring. While some have suggested that Sufis are distant from politics, this paper looks at events in Syria and Egypt, and how Sufis have been active in playing a political role in terms of calls for the dismissal of authoritarian leaders, as well as in the post-regime politics of the states. In the case of Syria, Muhammad al-Yaqoubi has taken a key role in advocating the removal of authoritarian regimes in the name of a democratic state. Similar calls have taken place in Egypt; in this case, Sufi groups have begun to form political parties for representation out of concern for the increase in political influence by the Muslim Brotherhood, as well as Salafi Muslim organizations.
Asad on the Secular
Authors: Rafudeen Auwais
Published: May 2021

This paper examines a South African debate on legislating Muslim marriages in the light of anthropologist Talal Asad’s critique developed in his Formations of the Secular (2003). It probes aspects of the debate under four Asadian themes: (1) the historicity of the secular, secularism, and secularization; (2) the place of power and the new articulations of discourses it creates; (3) the state as the arm of that power; and (4) the interconnections (or dislocations) among law, ethics, and the organic environment (habitus). I argue that Asad illumines the debate in the following ways: (1) by providing a deeper historical and philosophical appreciation of its terms of reference, given that the proposed legislation will be subject to South Africa’s secular Bill of Rights and constitution; (2) by requiring us to examine and interrogate the genealogies of such particular hegemonic discourses as human rights, which some participants appear to present as ahistorical and privileged; and (3) by showing, through the concept of habitus, why this debate needs to go beyond its present piecemeal legal nature and develop an appreciation of the organic linkages among the Shari‘ah, morality, community, and self. Yet inevitable nuances are produced when applying Asad’s ideas to the South African context.
TERMS OF CONSIDERATION OF COMPLAINTS AGAINST THE DECISION TO INITIATE A CRIMINAL CASE AND THEIR IMPACT ON THE PRELIMINARY INVESTIGATION
Authors: Mordvinov A.V.
Published: May 2021

The article points out the need to determine the permissible time limits for appealing the decision to initiate a criminal case and the time limits for its consideration. The problems arising in connection with the absence of a fixed time limit for appealing the decision to initiate a criminal case are highlighted. Conclusions by establishing a maximum term of appeal said decision and a maximum period of adjudication of the said complaint. The practical significance of the study lies in the development of problems related to the terms of appeal in court against the decision to initiate a criminal case, and in the formulation of proposals for their solution. The terms of filing a complaint against the decision to initiate a criminal case, as well as the terms of their consideration, are proposed. The opinion on the need to grant the right to the court to make specific decisions on the results of the consideration of this complaint in order to exclude repeated consideration of similar complaints by the court is substantiated. It is indicated that it is inadmissible to appeal against the decision to initiate a criminal case on the fact of committing a crime.
