Published: April 2022

Представлены результаты экспериментальных исследований фазового превращения в композитных пленках системы Se-Cu, полученных в вакууме в процессе последовательного термического осаждения селена и меди на стеклянную подложку. При фиксированной толщине слоя селена (45 нм) исследовалось влияние толщины слоя меди (40-115 нм) на фазовый состав синтезированных пленок, формируемых в процессе взрывной кристаллизации, происходящей при взаимодействии горячих кластеров меди с легкоплавким селеном. Установлено, что последующий термический отжиг синтезированных пленок сопровождается существенным изменением их фазового состава и спектров оптического пропускания. Ключевые слова: фазовые превращения, композитные пленки системы Se-Cu, взрывная кристаллизация, термический отжиг, оптические свойства.

Predicting mortality in ICU Patients with heart failure using interpretable machine learning model (Preprint)
Authors: Li Jili , Liu Siru , Hu Yundi , Zhu Lingfeng , Mao Yujia , Liu Jialin
Published: April 2022

BACKGROUND

Heart failure (HF) is a common disease and a major public health problem. The HF mortality prediction is critical for developing individualized prevention and treatment plans. However, due to their lack of interpretability, most HF mortality prediction models have not yet reached clinical practice.

OBJECTIVE

We aimed to develop an interpretable model to predict the risk mortality for HF patients in intensive care unit (ICU) and use the Shapley additive explanation (SHAP) method to explain the extreme gradient boosting (XGBoost) model and explore prognostic factors for HF.

METHODS

In this retrospective cohort study, we achieved model development and performance comparison on the eICU Collaborative Research Database (eICU-CRD). We extracted data during the first 24 hours of each ICU admission and the data set was randomly divided, with 70% used for model training and 30% for model validation. The prediction performance of the XGBoost model was compared with three other machine learning models by the areas under the receiver operating characteristic curve (AUROC). Moreover, we used the Shapley additive explanation SHAP method to explain the XGBoost model.

RESULTS

A total of 2,798 eligible patients with HF were included in the final cohort for this study. The observed in-hospital mortality of patients with HF was 9.97%. Comparatively, the XGBoost model had the highest predictive performance among four models (AUC 0.824, 95% Confidence Interval (CI) 0.7766 to 0.8708), while support vector machine (SVM) had the poorest generalization ability (AUC 0.701, 95% CI 0.6433 to 0.7582). The decision curve showed that the net benefit of the XGBoost model surpassed those of other machine learning models at 10%~28% threshold probabilities. The SHAP method reveals the top 20 predictors of HF according to the importance ranking and the average of the blood urea nitrogen was recognized as the most important predictor variable.

CONCLUSIONS

The interpretable predictive model helps physicians more accurately predict the mortality risk in ICU Patients with HF. This will help physicians to provide better treatment plan and optimal resource allocation for their patients. In addition, the interpretable framework can increase the transparency of the model and facilitates physicians to understand the reliability of the predictive model.
Insomnia as an Unmet Need in Patients With Chronic Hematological Cancer: Protocol for a Randomized Controlled Trial Evaluating a Consumer-Based Meditation App for Treatment of Sleep Disturbance (Preprint)
Authors: Huberty Jennifer , Bhuiyan Nishat , Eckert Ryan , Larkey Linda , Petrov Megan , Todd Michael , Mesa Ruben
Published: April 2022

BACKGROUND

To address the need for long-term, accessible, nonpharmacologic interventions targeting sleep in patients with chronic hematological cancer, we propose the first randomized controlled trial to determine the effects of a consumer-based mobile meditation app, Calm, on sleep disturbance in this population.

OBJECTIVE

This study aims to test the efficacy of daily meditation delivered via Calm compared with a health education podcast control group in improving the primary outcome of self-reported sleep disturbance, as well as secondary sleep outcomes, including sleep impairment and sleep efficiency; test the efficacy of daily meditation delivered via Calm compared with a health education podcast control group on inflammatory markers, fatigue, and emotional distress; and explore free-living use during a 12-week follow-up period and the sustained effects of Calm in patients with chronic hematological cancer.

METHODS

In a double-blinded randomized controlled trial, we will recruit 276 patients with chronic hematological cancer to an 8-week app-based wellness intervention—the active, daily, app-based meditation intervention or the health education podcast app control group, followed by a 12-week follow-up period. Participants will be asked to use their assigned app for at least 10 minutes per day during the 8-week intervention period; complete web-based surveys assessing self-reported sleep disturbance, fatigue, and emotional distress at baseline, 8 weeks, and 20 weeks; complete sleep diaries and wear an actigraphy device during the 8-week intervention period and at 20 weeks; and complete blood draws to assess inflammatory markers (tumor necrosis factor-α, interleukin-6, interleukin-8, and C-reactive protein) at baseline, 8 weeks, and 20 weeks.

RESULTS

This project was funded by the National Institutes of Health National Cancer Institute (R01CA262041). The projects began in April 2022, and study recruitment is scheduled to begin in October 2022, with a total project duration of 5 years. We anticipate that we will be able to achieve our enrollment goal of 276 patients with chronic hematological cancers within the allotted project time frame.

CONCLUSIONS

This research will contribute to broader public health efforts by providing researchers and clinicians with an evidence-based commercial product to improve sleep in the long term in an underserved and understudied cancer population with a high incidence of sleep disturbance.

Towards Enhancement of Students Achievement in Physics Using Concept Mapping Strategy and Guided Discovery Method
Authors: Achor Emmanuel E. , Bileya Samuel G.
Published: May 2022

This study investigated the relative effectiveness of Concept Mapping Strategy (CMS) and Guided Discovery Method (GDM) in enhancing students achievement in Physics. Gender influence on students achievement was also examined. A total of one hundred and fifteen (115) secondary school Physics students were involved in the study; the research work was carried out in the Wukari Education Zone of Taraba State. This research work adapted a quasi-experimental research design involving pre-test and post-test. Three research questions and three hypotheses were raised. Physics Achievement Test (PAT) was used for data collection. The items of PAT were subjected to item analysis. The reliability coefficient of the instrument was obtained using Kuder-Richardson 20 formula is .8. Mean and standard deviation was used to answer the research questions, while Analysis of Covariance was used to test the hypotheses formulated at .05 significance level. From the analysis, it is revealed that a statistically significant difference exists in the mean academic achievement scores of students taught physics using CMS and those taught using GDM in favor of CMS. Gender differences are not statistically significant in the mean academic achievement scores for both CMS and GDM groups. It is evident from the findings of this study that the use of CMS could provide a good way for students to learn Physics. It is recommended, based on the findings of the study, that Physics teachers should be encouraged to use a CMS while teaching Physics concepts to actively involve the students in identifying relationships in concepts. Government should utilize the services of various professional bodies like the Science Teachers Association of Nigeria (STAN) in collaboration with the Nigeria Educational Research and Development Centre (NERDC) to organize seminars, workshops, conferences, in-service training and symposia to inform and train physics teachers on the use of innovative teaching method especially concept-mapping.
The market and the masses: From chaotic corners to social media (re)tail events
Authors: Hansen Kristian Bondo
Published: April 2022

In this essay, I examine and discuss the relationship between the market and the masses in light of recent retail-driven surges in the stock prices of firms like GameStop and AMC. Using two historical snapshots, I draw out similarities and differences between the way the collective power and rationality (or lack thereof) of the masses was portrayed in late-nineteenth and early-twentieth-century market literature and in recent debates about retail investor inclusion and social media or social trading platform-driven market volatility. The main difference between the historical discourse and the present situation is that the new digital market-expanding technologies enable effective retail investor mobilization and thus, increase the retail swarms’ market-moving powers, which were previously less agile and forceful. However, eased and widened market access also transforms digital life into alternative data that is subjected to age-old strategies of market exploitation.
A Critical Analysis of Drug Courts in Chile
Authors: Cuneo Silvio , Medina González Paula
Published: April 2022

This paper is a critical study of the Drug Courts in Chile. To this end, it analyses the regulatory context in which they were created within the criminal legislation regarding illicit drug trafficking. Without questioning the merits of drug treatment, the idea that drug courts are a valid alternative to incarceration is here challenged. Rather, they widen the punitive net that complements the extreme punitiveness of criminal drug legislation. Furthermore, the eligibility requirements established in Chile's drug courts prevent many people who might need it from the possibility of accessing treatment, given that as they are presently structured, drug courts combine and confuse public health criteria with notions of dangerousness. In the conclusion, maintaining and even increasing the budget of drug treatment is recommended. Nevertheless, the separation of criminal law assessments or charges from public health criteria is proposed. Likewise, as a public policy in criminal matters on drugs, it is recommended the decriminalisation of behaviours and the reduction of penalties in order to build a real path that is decriminalising and respectful of human dignity.

Published: April 2022

Policiais realizam entrevistas com vítimas, testemunhas, e suspeitos para obter informações, sendo a acurácia e a quantidade destas informações diretamente relacionadas às técnicas de entrevista utilizadas. Uma entrevista com técnicas inadequadas tende a gerar poucas informações e potencialmente imprecisas, prejudicando o processo investigativo e o sistema de justiça. Já uma entrevista com técnicas adequadas é capaz de resultar em um maior número de informações confiáveis, preservando os direitos dos entrevistados. Neste artigo de revisão narrativa são apresentadas técnicas de entrevista investigativa e sua importância para a obtenção de informações confiáveis em oitivas e interrogatórios. Em seguida, apresenta-se um exemplo de como a entrevista investigativa foi implementada no Reino Unido, demonstrando como a aproximação entre pesquisadores e policiais pode auxiliar no processo de implementação e avaliação de treinamento.
role of constitutional courts in taming adverse impact of new technologies in the criminal proceedings
Authors: Marcia Michalina
Published: April 2022

This article presents the impact of constitutional courts in shaping the fair trial standards in the context of new technologies application in the criminal proceedings. Surveillance measures based on the use of new technologies by law enforcement agencies are highly intrusive in nature and may violate not only the constitutional right to privacy, but also, in the author's opinion, guarantees of the fair trial and procedural rights of the suspect. The aim of the article is to indicate to what extent constitutional courts have contributed to establishing the procedural standards in the activities of gathering evidence using new technologies (regarding both content and metadata), as well as to present potential problems in this area that courts will have to face in the future.
impact of the case law of the Constitutional Tribunal on the standard of detention on remand in Poland
Authors: Sakowicz Andrzej
Published: April 2022

Detention on remand is intrinsically linked to the fundamental rights and freedoms of the individual and, in particular, to personal freedom, the right to a fair trial and   the principle of the presumption of innocence.
This paper explores the constitutional dimension of the application of detention on remand in Poland. Its first part outlines the constitutional values that are violated as a result of detention on remand. The status of the principle of proportionality is pointed out, both in constitutional law and in the criminal law procedure. In further parts, the article presents the role of the Constitutional Tribunal in Poland and analyzes its case law on detention on remand. The jurisprudence of the Constitutional Tribunal in Poland emphasizes the directive to minimize the duration and the principle of proportionality of preventive measures, which imply that detention on remand may only be used ultima ratio.  In particular, the paper focuses on the rulings concerning the premises for detention on remand, the access to the file of the pre-trial proceedings in the part concerning the decision to apply detention on remand, the access of the persons detained on remand to defense counsels, the duration of detention on remand, and the contact of the persons subject to the most severe preventive measure with their loved ones.

Estas historias de comunidades, leyendas, cuentos y sátiras escritos en 1985, forman parte de un cúmulo de trabajos, publicaciones, ilustraciones y otras manifestaciones del arte, la cultura, el libre albedrío, que se multiplican a medida que se acaban el siglo y el milenio, y se encienden como luces en estos últimos años. Claro está que esas voces estuvieron siempre allí, en las comunidades, en sus reuniones y asambleas, en sus tradiciones orales familiares. Este mundo no sólo brota del inframundo subiendo por la ceiba infinita de las estrellas y allí se derrama regresa, aquí estaba. Pero el devenir de su historia reciente es triste, apenas espera recuperar la crónica o testimonio de la historia más sencilla, como las que se presentan aquí sobre la fundación de cada localidad creada, hace sólo unas décadas, tanto como en los relatos, que con la misma ansiedad del historiador registran nombres, fechas, dimensiones del esfuerzo, dificultades inconcebibles, y también gozos y victorias, y en los cuentos y muchos otros géneros cada vez con mayor frecuencia y creatividad.

La tradición oral es muy rica en las comunidades indígenas, ya que representa la base fundamental de la preservación de la palabra que ha venido transmitiendo de padres a hijos. Existe un cúmulo de leyendas y narraciones que al parecer son simplemente “cuentos”, que al contarlas divierten a la gente, pero han pasado a formar parte de la historia del pueblo, no escrita conforme a las características latinas, sino permaneciendo en la mente y en la palabra de los pueblos indígenas. Cuando nuestros padres cuentan lo que han recibido de sus padres, es nuestro motivo de reír, llorar, cantar, convivir armónicamente con nuestros hermanos, nuestra familia y nuestra comunidad, ya que son las primeras palabras, los primeros conocimientos y los primeros mandamientos que nos conducen al reencuentro con nuestros antepasados. De ahí parten la enseñanza y la solidaridad de nuestros pueblos.

Published: April 2022

Abstract: Cement concrete reinforced with steel bars is an extremely popular construction material. One major flaw, namely its susceptibility to environmental attack, can severely reduce the strength and life of these structures. External reinforcement using steel plates have been used in earlier attempts to rehabilitate these structures. The most important problem that limited their wider application is corrosion. This project emphasize on Rehabilitation of R.C.C. structures. The purpose of this project is to highlight the various techniques of repair and rehabilitation methods to be undertaken for structures with defects and deficiencies that necessitate rehabilitation. Repair and Rehabilitation methods currently used are reviewed on the basis of present knowledge and the merits of a holistic system approach. This project focuses on visible symptoms of the problem rather than on invisible problems as well as the possible causes behind them. This project focuses on various techniques and repair materials used for the satisfactory performance of the repaired structure. This project presents an analysis of concrete illnesses, and problems leading to unsatisfactory performance of repaired concrete structure. This project describes the analysis the types of surface preparations that are commonly adopted in Indian conditions. This project highlights the problem of reinforcing steel corrosion in concrete structures and attempts to provide the remedial measures available in design to mitigate the effects of corrosion. In view of these limitations the various types of coatings are available and the precautions to be taken in the selection of coatings systems are also discussed. This also highlights the importance of epoxy resins and various methods of epoxy in the construction applications such as repairing of cracks, patching, grouting of concrete, structural adhesives and anti-corrosive linings etc. The conclusive part deals with cost comparison between present approximate estimated cost of new building & rehabilited building.

Abstract: The purpose of this study is to compare VAR, ARIMA and SARIMA methods in an attempt to generate sales forecasting in Store xyz with high accuracy. This study will compare the results of sales forecasting with time series forecasting model of Vector Auto Regression (VAR), Autoregressive Integrated Moving Average (ARIMA) and Seasonal Autoregressive Integrated Moving Average (SARIMA). VAR or ARIMA model still accurate when the time series data is only in a short period, these models is accurate on short period forecasting but less accurate on long period forecasting. Meanwhile Seasonal Autoregressive Integrate Moving Average is more accurate on forecasting seasonal time series data, either it’s pattern shows trend or not all three models are compared with forecasting data showing seasonal patterns. The data used is the data of super mart retail store, sales from 2017 to 2022. Accuracy level of each model is measured by comparing the percentage of forecasting value with the actual value. This value is called Mean Absolute Deviation (MAD). Based on the comparison result, the best model with the smallest MAD value is SARIMA model (0,1,0) (0,1,0)12 with MAD value 0.122. From the comparison results can be concluded that the SARIMA model is optimal to be used as a model for further forecasting Keywords: Machine Learning, sales prediction, ARIMA, SARIMA, VAR, PYTHON, Anaconda navigator, Jupiter notebook.

Authors: Gawande R. R. , Kite D. V. , Lande B. V.
Published: April 2022

Abstract: The practice of gathering a mature crop from the fields is known as harvesting. In most parts of the globe, automated combine harvesters are utilized to harvest crops. These autonomous harvesters are not appropriate for farmers with tiny plots of land, usually less than 2-3 acres. As a result, it is critical to create the tiny harvester, which is significantly less expensive and more accessible to small-scale farmers. Cutting blades for these tiny harvesters currently on the market have issues with high cutting resistance, high energy consumption, and poor cut quality. A bionic blade was designed by extracting the cutting teeth profile curve of the beetle palate using bionics concepts. The analysis of designed bionic blade was carried out using Ansys software. The result showed that the total deformation and stresses on bionic blade was less than the ordinary blade. Keywords: harvester, cutting blade, bionic, deformation, stresses
Evaluation of the Effect of RAP and Lime on Geotechnical Properties of Clayey Soil
Authors: Bhatt Alkesh , Suman Sanjeev
Published: April 2022

Abstract: Road network plays a large role in the rapid development of the economy of a country, providing connectivity to remote areas for various transportation activities. India ranks second in the world in terms of length of road network after the United States. The major road network in the urban locality consists of bituminous pavements periodically resurfaced during maintenance. From the milling process, reclaimed asphalt pavement (RAP) is obtained. Additionally, RAP can be used for the utilization of recycled asphalt pavement (RAP) materials in subgrade soil. Reclaimed Asphalt Pavement (RAP) is being used in this case study to stabilize the subgrade soil collected from Crop Research Center (CRC), Govind Ballabh Pant University, Tanda Range, Uttarakhand (29°01'09.7"N, 79°28'55.9"E). To conduct the experimental program, a variable amount of RAP percentages viz., 5, 10, 15, and 20%, and different percentages of lime i.e., 2, 4, 6, and 8% were mixed with natural soil. Based on gradation, Standard Proctor Test (SPT), Unconfined Compressive Strength (UCS), California Bearing Ratio (CBR), and Specific gravity, the characteristics of RAP-soils with added lime were evaluated. For soil mixture including 10% RAP and 4% lime, a maximum MDD of 19.04 and a percentage increase in compaction of 11.93% was observed. OMC value was observed as 11.35%, which further decreased as RAP content increased. Due to RAP containing coarse aggregate, a higher CBR value was obtained due to the harder sample surface. For all soil mixers of 15% RAP and 4% lime, unsoaked CBR and soaked CBR values were found to be 31.39% and 18.69% respectively. Percentage increases in their respective CBR values were 868.83% and 662.86%. for every percentage of lime variation, maximum CBR was obtained at 15% RAP, and maximum CBR value for soaked CBR was obtained for soil with 15% RAP and 2% lime, whereas for unsoaked CBR, it was obtained for soil with 15% RAP and 4% lime. Maximum UCS values of 412.45 kN/m2 , 606.81 kN/m2 and 857.62 kN/m2 were observed on 3rd, 7th and 14th days for soil mix with 15% RAP and 4% lime, with percentage increase of 291.17%, 249.40% and 387.78% respectively. Based on the results of the study, RAP materials can be effectively used in the soil subgrade, sub-base, and base of flexible pavements, reducing the cost of construction. Keywords: Reclaimed Asphalt Pavement (RAP), Lime, CBR, SPT, UCS, OMC, MDD.

Abstract: Crop harvesting is the important part in agricultural field. The use of crop reaper in country can minimize the product cost which will be result in economic development of agricultural production. This paper is providing the design and fabrication of mechanically operated crop reaper machine. In the current situation in our country there are not more proper cost effective crop reaper and most of the farmers are using manually traditional crop cutting mechanism, the traditional use of harvesting mechanism is more un intresting, time consuming and not able to develop the agricultural sector as needed. Depending on the problem stated in existing crop reaper to satisfy the need of farmers and to meet the requirement of the objective of the problem. This paper addresses a Crop cutting Machine which is fabricated with very simple mechanisms at very low cost. Cutting of crop is one of the important agricultural operations which demand considerable amount of Labour. The availability and cost of labour during cutting season are the serious problem. The Shortage of labour during harvesting season and vagaries of the weather cause great losses to the farmers it is therefore, essential to adopt the mechanical methods so that the timeliness in cutting operation could be ensured. The use of mechanical harvesting device has been increased in the recent years. Farmers using reapers or combines to harvest their crops but these means especially combine; these are very costly making it un-affordable to most of the small farmers. Although, some manual operated reapers were developed. But, due to limitations of manual power, none of them become popular as the power available for transportation of the machine as well as cutting and conveying of the crop was not sufficient. In this research, we are study and fabricate a Crop Cutting Machine at very low cost and techniques were carried out.

Among the concerns about youth wellbeing during the COVID-19 pandemic, one well-documented impact is youth motivation, particularly in relation to schooling. Yet many questions remain: How are youth experiencing motivation? What factors affect their motivation? How are youth differentially experiencing motivation? This article addresses young people’s experiences of motivation during the first wave of the pandemic as explored through participatory visual research. In Spring 2020, the Quebec private and public secondary school systems responded very differently to school closures. Private schools pivoted to distance learning within about two weeks, whereas public schools took almost two months to provide formal instruction. Bringing youth’s accounts of motivation into conversation with youth’s concerns about the inequities across the private and public school systems offers a rich opportunity to revisit Self-Determination Theory as an established theory of motivation. Youth’s analyses urge us to revisit the conceptualization of “structure” within this theory and how structure might offer a junction for accounting for more macrostructural inequalities within motivation research.

Several armed conflicts and military troop interventions have been associated with minor pandemics, however, not always, and with the extent varied. e.g. during the most catastrophic loss of lives in the Bosnian Conflict in 1993-95 where 160,000 civilians and soldiers fell into mass graves, only one small epidemic of Hepatitis A was reported to the European branch of WHO.                                                       In contrast, epidemics of cholera in Haiti, not related to war but associated with troop deployment (UN battalion from Nepal) in 2014, led to a devastating epidemic of cholera in the Artibonite River District with 1,000s of deaths. The same was reported during civil war and genocide in Rwanda in 1988-98 where hundreds died, and refugees of war-related exodus from Rwanda to the DRC in Goma. Finally, pipeline and water supply devastation during war in Yemen, led to the largest cholera outbreak in Yemen (1-3). Therefore, fear of epidemics, especially during COVID-19 Omicron wave is of concern mainly when the numbers of positive cases in Austria and other EU countries are increasing.                                                       The aim of this study was to report the results of COVID-19 antigen testing in those escaping from war in Ukraine.

Published: April 2022

The ideas of optimization of constructive solutions of protective erections of nuclear power stations are presented. A problem of such optimization for the securing of nuclear and radiation safety for different regime of nuclear power stations exploitation, including extreme action, is very topical at present time. Modern home and international achievements on the considered subjects are demonstrated and modern demands, analysis methods, and problems of design of erections of nuclear power stations that give an opportunity to assure their safety exploitation under collision of flying objects are given as well. The results confirm wide opportunities of improvement of the constructive solutions of protective shells of reactor sections of nuclear power stations with the application of innovative materials that give the prospects to economize the material resources considerably and to raise the reliability and safety of exploitation of erections of nuclear power stations simultaneously.
The economic feasibility of taking into account the joint work of load-bearing and enclosing elements in large-span wooden spatial structures
Authors: Pyatikrestovsky Konstantin P. , Sokolov Boris S.
Published: April 2022

Large-span wooden spatial structures in the form of domes, developed in JSC Research Center of Construction under the leadership of A.A. Pogoreltsev, are built in large numbers for roofing various buildings. Such designs have high performance indicators and continue to improve. In 2020 the Manual on accounting for the joint work of the frame and fencing in wooden spatial structures of buildings and structures was developed as an addition to SP 64.13330.2017, containing examples of strength calculation and optimization of rib cross-section dimensions, as well as an example of determining the long-term strength of the shell cladding. These structures, in fact unique, are designed so far in the margin of safety without taking into account the participation of the enclosing part (panels, decking, etc.) in the bearing loads. Taking into account the work of the decking, especially when exposed to asymmetric loads, can lead to material savings. In addition to the above theory of nonlinear shell calculation, the authors have also developed a calculation of composite anisotropic panels operating under complex stress conditions, i.e. under biaxial compression (tension) and shear. The calculation of such structures under both short-term and long-term loads presents certain difficulties and requires the introduction of strength theories and criteria for their description that are unusual for specialists of design organizations.

Aim/purpose – The underground economy is a major challenge across the world affect- ing both developed and developing economies. South Africa is no exception to this phenomenon and has lost billions of rands due to the underground economy. The aim of this study is to estimate the size of the underground economy in South Africa. Design/methodology/approach – The study used quarterly time series data from 2000 to 2020 and employed the Currency Demand Approach (CDA) for modeling the under- ground economy. Findings – The model results revealed that the underground economy is positively influ- enced by unemployment rate, tax burden, and social benefits granted by the government, however it is negatively influenced by Nominal Gross Domestic Product (NGDP), deposit interest rate, and self-employment rate. Furthermore, the study showed that there was a distinct growth of the underground economy, from 23.9% of GDP in 2003 to 34.5% of GDP in 2019. On average, the underground economy represented 28.8% of GDP for the period 2003 to 2020. Research implications/limitations – This model can be used in conjunction with other models to observe the trend in the South African underground economic activities. The South African government should take note of the spiraling growth of this economy and come up with measures to curb this growth to protect the formal economy. Originality/value/contribution – This study makes a significant contribution to the body of knowledge in this research area and provides much needed insights into the magnitude of the underground economy and the extent of tax evasion in South Africa. Keywords: underground economy, South Africa, currency demand approach. JEL Classification: C32, O17, H26, C53.
Siyasah Dusturiyyah sebagai Sistem Perpolitikan dalam Al-Qur’an
Authors: Muthalib Salman Abdul , Mohd Pauzi Muhammad Faizur Ridha Bin
Published: April 2022

Siyasah dusturiyyah so far has not been revealed in detail. In the world history stage, it can be seen that the good or bad of a country depends on the system of government. The Qur'an has clearly stated the necessity of government. Allah SWT ordered the Messenger of Allah to get used to and train himself in government affairs. Thus, to find the ideal of Islam in the process of administering the government, the title of the thesis on "Interpretation of the Siyāsah Dusturiyāh Verses (Study of Government Systems)" is very interesting to study. Data analysis was carried out using thematic (Maudhu'ï). In the thematic method, all related verses are collected, then studied in more depth from various aspects related to them. This method is also supported by arguments or truths that can be justified scientifically and rationally. Based on the method used, the Qur'an explains that leadership in the dusturiyah siyāsah can be adapted to every era. Leadership in Islam is natural for every human being as well as motivates Islamic leadership. Humans are entrusted by Allah SWT to be the caliph to lead the people in religion and the world, also regulate the people and guard religion and politics. The system of government referred to in the Qur'an consists of five: the Imamate, the People and Their Obligations, Bai'at, Ahl al-Hall Wa al-Aqd, and Wizarah. Siyasah dusturiyyah selama ini belum terungkap secara terperinci. Dalam pentas sejarah dunia dapat dilihat bahwa baik buruknya negara tergantung dengan sistem pemerintahan. Alquran secara tegas telah menetapkan keharusan adanya pemerintahan. Allah Swt memerintahkan Rasulullah Saw untuk membiasakan dan melatih diri dalam urusan kepemerintahan. Dengan demikian untuk menemukan idealitas Islam dalam proses penyelenggaraan pemerintahan, maka judul skripsi tentang “Penafsiran Ayat-Ayat Siyāsah Dusturiyāh (Kajian Sistem Pemerintahan)” sangat menarik untuk dikaji. Analisis data yang dilakukan dengan menggunakan tematik (Maudhu’ï). Dalam metode tematik semua ayat yang berkaitan dikumpulkan, kemudian dikaji secara lebih mendalam dari berbagai aspek yang berkaitan dengannya. Dalam metode ini juga didukung dengan dalil-dalil atau kebenaran yang dapat dipertanggungjawabkan secara ilmiah dan rasional. Berdasarkan metode yang digunakan, Alquran menjelaskan bahwa kepemimpinan dalam siyāsah dusturiyāh dapat disesuaikan dengan setiap zaman. Kepemimpinan dalam Islam merupakan fitrah bagi setiap manusia sekaligus memotivasi kepemimpinan yang Islami. Manusia di amanahi Allah Swt untuk menjadi khalifah untuk memimpin umat dalam agama dan dunia, juga mengatur umat serta menjaga agama dan politik. Sistem pemerintahan yang disebut di dalam Alquran terdiri dari lima: yaitu Imamah, Rakyat dan Kewajibannya, Bai’at, Ahl al-Hall Wa al-Aqd, dan Wizarah.
Konsep Perbudakan menurut Sayyid Quṭb dalam Tafsir Fi Zilal al-Qur’an

Published: April 2022

Slaves are people who do not have independence in people's lives and have the fate of being traded as objects, sometimes even being treated inhumanely. In historical records, slavery existed before Islam, and when Islam came, slaves were called slaves and this religion forbade all forms of slavery practices with a call to free them. This paper attempts to discuss how to interpret slavery and how to free slaves according to Sayyid Quṭb in Tafsir Fī ilāl al-Qur'ān. The research method used in this study is the mauḍū'i (thematic) method, which is a method that collects verses from the Qur'an that have the same purpose. The data used in this study is the Tafsir Fī ilāl al-Qur'ān. The results of this study indicate that the concept of slavery according to Sayyid Qutb is aimed at conditions of emergency (compulsion), that only in emergency conditions is slavery allowed, such as being allowed to marry slave women during the war, and only slaves who are obtained as prisoners in the fī sabīlillah war are one thing. the only slavery recognized in Islam. While the way of freeing slaves is done by establishing slave freedom through the payment of kafarat, for example, someone frees a slave before having intercourse with a wife who is forbidden to him through zhihar. Budak merupakan orang yang tidak memiliki kemerdekaan dalam hiduporang dan bernasib sebagai benda yang diperjualbelikan, bahkan kadang-kadang diperlakukan tidak manusiawi. Dalam catatan sejarah, perbudakan sudah ada sebelum Islam, dan ketika Islam datang, budak disebut hamba sahaya dan agama ini melarang seluruh bentuk praktik perbudakan dengan seruan memerdekakannya. Tulisan ini berupaya membahas tentang bagaimana penafsiran perbudakan dan cara pembebasan budak menurut Sayyid Quṭb dalam Tafsir Fī Ẓilāl al-Qur’ān. Metode penelitian yang digunakan dalam penelitian ini yaitu metode mauḍū’i (tematik), yaitu metode yang menghimpun ayat-ayat al-Qur’an yang mempunyai maksud yang sama. Data yang digunakan dalam kajian ini adalah Tafsir Fī Ẓilāl al-Qur’ān. Hasil penelitian ini menunjukkan bahwa konsep perbudakan menurut Sayyid Qutb tertuju pada kondisi darurat (keterpaksaan), bahwasanya hanya dalam kondisi darurat diperbolehkannya perbudakan, seperti dibolehkannya menikah dengan wanita budak pada masa peperangan, dan hanya budak yang diperoleh sebagai tawanan di dalam perang fī sabīlillah lah satu-satunya perbudakan diakui dalam Islam. Sedangkan cara pembebasan budak dilakukan dengan menetapkan kemerdekaan budak melalui pembayaran kafarat, misalnya seseorang memerdekakan budak sebelum menggauli istri yang di haramkan kepada dirinya melalui zhihar.
