أنثولوجيا الإسلام الليبرالي
Authors: الرحموني محمد
Published: January 2023

تعرض هذه الدراسة أنثولوجيا الإسلام الليبرالي، وذلك من خلال النظر في الجدل الذي أثير منذ عصر النهضة العربية الحديثة حول علاقة الإسلام بالحداثة عمومًا، وبالليبرالية تحديدًا. وقد ظل هذا الجدل مرتهنًا في جزء كبير منه لتقلبات علاقة المسلمين بالغرب. وأمكننا رصد لحظتين رئيستين في هذا الجدل؛ لحظة كان المسلمون مطالبين بمراجعة نصوصهم الدينية التأسيسية والتراثية حتى يصبحوا ليبراليين على النمط الغربي، ولحظة أصبحوا فيها يطالبون الغرب بمراجعة قيمه الليبرالية والكفّ عن النظرة الاستقطابية لعلاقة الإسلام بالليبرالية. واللحظة الثانية هي التي شهدت ميلاد مقولة "الإسلام الليبرالي" أشتهرت بفضل كتابات تشارلز كورزمان بالخصوص، وقد تأثرت بكتابات جون رولز عن الليبرالية، وبمقولات "نهاية التاريخ" لفرانسيس فوكوياما و"صدام الحضارات" لصمويل هنتنغتون.
العقل العام في سياق فلسفة رولز السياسية
Authors: رجا البهلول
Published: January 2023

تناقش هذه الدراسة قضايا العقل العام والهوية والدين (أو العقيدة الشاملة) كما تتبدى في فلسفة جون رولز السياسية، وتُناقش كذلك الانتقادات التي واجهتها مواقف رولز من هذه القضايا عند بعض النقاد، وبالأخص الجماعاتيين وأتباع العقائد الشاملة. نتوقف أيضًا عند مفهوم المعقولية والمسوغات العامة، ونطرح سؤالًا حول ما إذا كانت هذه المفاهيم تحظى بأي مشروعية تسمو فوق العقائد، وتحديدًا ما إذا كان عقل رولز العام لا يعدو كونه عقلًا ليبراليًا يرتدي لبوس العمومية من دون وجه حق
Is more comfortable reading possible with collaborative digital games? An experimental study
Authors: ÖZER ŞANAL Seda
Published: January 2023

In this study, which is based on the fact that the nature of learning is and should be understood on the basis of social constructivism, interaction and collaboration in language development are explored and digital games are discussed as an instructional technology. For digital games developed with learning in mind, the effects of educational change for learners have not yet been fully explored. The effects of digital games supported with reciprocal activities related to reading comprehension, reading motivation, and reading anxiety for science texts were investigated in this study. Eighty-five participants were randomly assigned to a group that played digital games without reciprocal activities (control group, n=43), and they were compared to a group that played digital games with reciprocal activities (experimental group, n=42), reading ten different texts over a ten-week period. The study used a quasi-experimental pretest-posttest design to compare reading comprehension, reading motivation, and reading anxiety outcomes. Considering the effectiveness of reciprocal activities, the participants who were supported by collaborative activities were more motivated and less anxious than those in the group that used the digital games without collaborative activities. These findings indicate that the use of collaborative activities should not be ignored when planning to employ the supporting role of any instructional technologies while teaching reading skills.
Examination of the correlation between e-learning readiness and achievement goal orientation of college students
Authors: SEVİM Neşe , EROL Osman , BAŞER GÜLSOY Vesile Gül
Published: January 2023

Students’ readiness for e-learning is necessary in order to make the e-learning process more effective. Readiness for e-learning refers to the degree of having pre-knowledge and skills, and affective characteristics such as the necessary attitude and motivation to experience this process most effectively. Academic orientations of the students also contribute to their perception of the quality of the learning process in online learning environments. Furthermore, e-learning creates a learner-centered learning approach that might be contrived to personal goal orientations. Hence this study aims to identify the relationship between achievement goal orientations and the e-learning readiness level of the students. Data were collected from 457 university students enrolled in a public university in Turkey. The University Students’ E-learning readiness Scale and 2X2 achievement goal orientation scale were used as the data collection tools. A canonical correlation analysis (CCA) was performed to analyze the data. This study revealed that there is a statistically significant relationship between e-learning readiness and achievement goal orientations of the students. Three of the four canonical correlations were statistically significant which indicates that variables' linear combinations were related.
Brazil’s cultural diplomacy: origins and modernity
Authors: Timofeeva Yulia
Published: January 2023

The article deals with the evolution of Brazil’s cultural diplomacy from the Empire till the present day. Special attention is paid to figures who contributed a lot to its development, namely the Emperor Pedro II, foreign minister Rio Branco, education minister Gustavo Capanema. The author divides cultural diplomacy evolution into several periods and concludes that it reached its heights under Lula da Silva in early XXI century. The president increased government role in financing cultural sphere and implemented various cultural programmes partly borrowed by neighbouring and some European states. After right-wing politicians came to power, cultural diplomacy has been suffering crisis, which manifested in the dissolution of Cultural Ministry, less investment in culture and return to some elements of elitist culture of the First Republic.
Determinants of Technical Efficiency of Public Universities in South Africa
Authors: Vuyolwethu Nkohla Tumi , Munacinga S. , Marwa N. , Ncwadi R.
Published: January 2023

Using a second-stage Data Envelope Analysis (DEA) model, this paper seeks to determine the drivers of efficiency for 23 public universities in South Africa for the period 2009-2016 with special attention given to the funding–efficiency nexus. Our Tobit results indicate that quality of staff, government funding, student fees, private income, and Gross Domestic Product (GDP) per capita are positive factors of efficiency, while the proportion of non-white to white staff was found as the determinant of inefficiency. It was concluded that adequate funding and proper management of income by the universities, economic growth and employment of high educated academic staff can increase efficiency levels of the public universities in South Africa. On the other hand, an increase of non-white to white staff in the South African public universities is a threat to the universities’ efficiency. It is, therefore, vital to allocate adequate funding for universities to improve their efficiency.
Inflation Spill-overs from BRIC to SADC Economies: The Impossible Trinity Theory Analysis
Authors: Qabhobho Thobekile , Khobai Hlalefang
Published: January 2023

This paper examined the potential inflation spill-over effects from BRIC to five SADC countries (Angola, Botswana, South Africa, Tanzania and Zambia) by using data collected for the period 1985-2020. Thirty-six (36) observations were used to obtain more reliable results with greater precision. Studies conducted on the impossible trinity argue that, in the case of highly financially integrated economies, domestic interest rates are tightly linked to the international interest rates if it is impossible to manipulate domestic interest rates. Specifically, interest rates for open economies tend to be influenced by international interest rates if these economies opt for free capital flows with a fixed exchange rate regime. Fisher's effect theory asserts that domestic interest rates trend positively with inflation rates. The principal method of research used is that of quantitative analysis. Given the empirical nature of the research, the paradigm employed is positivist. This paper employed the generalised method of moments (GMM) model, the Johansen cointegration procedure, and the Granger causality test in a vector error correction (VEC) model. The findings indicated that the fixed-exchange-rate regimes (soft pegs and hard pegs) are associated with high responsiveness of the domestic inflation rate to the foreign countries’ inflation rates, rather than to floating exchange-rate regimes (free-floating and managed floats). The policy implications for control of inflation in SADC economies are that, because of the financial market integration increase between SADC and BRIC economies, monetary authorities in SADC countries should consider floating exchange rate regimes (managed-floats or free-floating).
Working Capital-targeting and Firms Life Cycle: Analysis of Persistence and Speed of Adjustment
Authors: Adibura Seidu Baba , Ndori Queku Yaw , Tackie George , Mensah John
Published: January 2023

This paper examined the dynamics of working capital targeting and corporate life cycle (CLC) of listed manufacturing and trading firms on the Ghana Stock Exchange (GSE). Annual data spanning 2008 to 2019 and Panel Dynamic OLS, Delay and Half-life were used for the empirical analysis. The paper found that working capital varies across the stages of CLC with cash holding exhibiting low-high-high-low-low pattern while inventory holding showing U-shape. There is relatively high persistence at each stage of CLC with no sequential order of transition in the stages of life-cycle. Firms’ working capital targeting showed very high rate of adjustment to changes in stages of CLC with cash holding targeting showing the highest speed of adjustment while inventory holding being slowest to adjustment. The results imply that firms’ working capital policies are markedly interacted with the transitional mechanism of CLC and, therefore, firms should continuously evaluate working capital targets within the corporate life-cycle transition process.
A Comparative Study of Social Media Marketing and Conventional Marketing – A Case Study
Authors: Katrodia Ankit
Published: January 2023

There has been an increase in the number of organisations using social media for marketing purposes, consistent with the popularity of social media for personal and corporate use. Consequently, organisations find it easy and convenient to use social media for marketing purposes. The study was in response to two problems. First, organisations now need to prioritise resources when it comes to marketing, but the returns from social media are unknown. Secondly, the impact of other marketing channels has rarely been evaluated. This study compared the usage of competing marketing channels to determine the one that is worth pursuing for an organisation if prioritisation is to be done. A case study approach was used, focusing on the XYZ Private Limited Company in South Africa. The quantitative research design was adopted as the strategy of inquiry, making use of closed questions in a questionnaire survey. Results indicated that, despite the growing prevalence of social media marketing, with Facebook and LinkedIn dominating the marketing, there was also a strong dependence on conventional marketing channels such as newspapers, magazines and direct mail by XYZ Private Limited. A multipronged approach remains key in marketing to enable reaching out to a diversity of clients but, if resources are limited, social media channels have proven to be cheaper in reaching out to young clients.

Authors: Kwasi Oppong Peter , Mensah John , Addae Matilda
Published: January 2023

High levels of brand awareness, image and credibility have a profound impact on customers’ favourable word-of-mouth behaviour, which can lead to an increase in market share. Despite the important role of brand awareness, image and credibility in supporting customers’ word-of- mouth behaviour, there are limited studies on the mediating role of brand credibility in the impact of brand awareness and image on word-of-mouth praise and activity in the herbal market. Hence, this paper aimed to investigate the impact of brand awareness and brand image on word-of-mouth activity and praise via the mediating role of brand credibility in the herbal market. Data were gathered from a sample of 265 customers in the Cape Coast herbal market using a systematic sampling technique. The research hypotheses were statistically analysed through structural equation modelling, using SPSS and Amos 26. The research found that the impact of brand awareness and brand image on word-of-mouth activity is not mediated by brand credibility. However, the effect of brand awareness and image on word-of-mouth praise is fully mediated by brand credibility. The research established that brand credibility is an important element in building brand awareness and image to strengthen word-of-mouth praise in the herbal market in Ghana.

Polish criminal law on ‘Work of a forced nature’
Authors: Pohl Łukasz
Published: January 2023

This article discusses Polish criminal law and its outlook on work of a forced nature. The discussion has three distinguishable aspects: (1) interpretation of the expression ‘work of a forced nature’, (2) relationship between human trafficking and work of a forced nature, and (3) suggestions for adequate amendments to criminal law provisions. Under (1), it is observed that the concept of work of a forced nature calls for an autonomous interpretation and that references to the Convention concerning Forced or Compulsory Labour (No. 29) of 1930, Art. 2(1 & 2) of which defines such labour, are not fully justified in the interpretation of this concept. Under (2), it is shown that human trafficking – within the meaning given to it by the Polish Criminal Code – covers only behaviour preceding the performance of work of a forced nature. Finally, under (3), a suggestion is made to introduce suitable amendments to the Polish Criminal Code, thereby creating new offence types, involving coercion of people to perform work or a service of a forced nature.
LSEC: Large-scale spectral ensemble clustering
Authors: Li Hongmin , Ye Xiucai , Imakura Akira , Sakurai Tetsuya
Published: January 2023

A fundamental problem in machine learning is ensemble clustering, that is, combining multiple base clusterings to obtain improved clustering result. However, most of the existing methods are unsuitable for large-scale ensemble clustering tasks owing to efficiency bottlenecks. In this paper, we propose a large-scale spectral ensemble clustering (LSEC) method to balance efficiency and effectiveness. In LSEC, a large-scale spectral clustering-based efficient ensemble generation framework is designed to generate various base clusterings with low computational complexity. Thereafter, all the base clusterings are combined using a bipartite graph partition-based consensus function to obtain improved consensus clustering results. The LSEC method achieves a lower computational complexity than most existing ensemble clustering methods. Experiments conducted on ten large-scale datasets demonstrate the efficiency and effectiveness of the LSEC method. The MATLAB code of the proposed method and experimental datasets are available at https://github.com/Li-Hongmin/MyPaperWithCode.

Published: January 2023

Accident severity prediction is a hot topic of research aimed at ensuring road safety as well as taking precautionary measures for anticipated future road crashes. In the past decades, both classical statistical methods and machine learning algorithms have been used to predict traffic crash severity. However, most of these models suffer from several drawbacks including low accuracy, and lack of interpretability for people. To address these issues, this paper proposed a hybrid of Balanced Bagging Classification (BBC) and Light Gradient Boosting Machine (LGBM) to improve the accuracy of crash severity prediction and eliminate the issues of bias and variance. To the best of the author’s knowledge, this is one of the pioneer studies which explores the application of BBC-LGBM to predict traffic crash severity. On the accident dataset of Great Britain (UK) from 2013 to 2019, the proposed model has demonstrated better performance when compared with other models such as Gaussian Naïve Bayes (GNB), Support vector machines (SVM), and Random Forest (RF). More specifically, the proposed model managed to achieve better performance among all metrics for the testing dataset (accuracy = 77.7%, precision = 75%, recall = 73%, F1-Score = 68%). Moreover, permutation importance is used to interpret the results and analyze the importance of each factor influencing crash severity. The accuracy-enhanced model is significant to several stakeholders including drivers for early alarm and government departments, insurance companies, and even hospitals for the services concerned about human lives and property damage in road crashes.
Efficiently mining maximal l-reachability co-location patterns from spatial data sets
Authors: Zou Muquan , Wang Lizhen , Wu Pingping , Tran Vanha
Published: January 2023

A co-location pattern is a set of spatial features that are strongly correlated in space. However, some of these patterns could be neglected if the prevalence metrics are based solely on the clique (or star) relationship. Hence, the l-reachability co-location pattern is proposed by introducing the l-reachability clique where the members of each instance pair can be reachable to each other in a given step length l. Because the average size of l-reachability co-location patterns tends to be longer, maximal l-reachability co-location pattern mining is researched in this paper. First, some sparsification strategies are introduced to shorten star neighborhood lists of instances in an updated graph called the l-reachability neighbor relationship graph, and then, they are grouped by their corresponding patterns. Second, candidate maximal l-reachability co-location patterns are iteratively detected in a size-independent way on bi-graphs that contain group keys and their intersection sets. Third, the prevalence of each candidate maximal l-reachability co-location pattern is checked in a binary search way with a natural l-reachability clique called the ⌊l/2⌋-reachability neighborhood list. Finally, the effectiveness and efficiency of our model and algorithms are analyzed by extensive comparison experiments on synthetic and real-world spatial data sets.

Intelligent decision support tool for optimizing stochastic inventory systems under uncertainty
Authors: Long Le Ngoc Bao , Kim Hwan-Seong , Cuong Truong Ngoc , You Sam-Sang
Published: January 2023

Pricing and production policies play a key role in ensuring the added value of supply chain systems. For perishable inventory management, the pricing and production lines must be manipulated dynamically since several uncertainties are involved in the system’s behavior. This study discusses the impact of dynamic pricing and production policies on an uncertain stochastic inventory system with perishable products. The mathematical model of the inventory management system under external disturbance is formulated using a continuous differential equation in which the price and production rates are considered as control factors to optimize total profits, which is described as an objective function. An analytical solution for the optimal pricing and production rate was obtained using the Hamilton-Jacobi-Bellman equation. The unknown disturbance was approximated using an intelligent approach called radial basis function neural network. Finally, extensive numerical simulations were presented to validate the theoretical results and optimization solutions (including the efficiency of the approximation of the unknown disturbance) for the dynamic pricing and production management strategy of an uncertain stochastic inventory system against volatile markets. The performance of the proposed method was analyzed under different stock level conditions, which highlighted the importance of keeping the inventory levels at an optimal range to ensure the profitability of business operations. This management strategy can assist a business with solutions for inventory policies while supporting decision-making processes to facilitate coping with production management disruptions.

A novel energy consumption prediction method for chillers based on an improved support vector machine
Authors: Cai Jianyang , Yang Haidong , Xu Kangkang
Published: January 2023

The energy consumption prediction of the chiller is an important means to reduce the energy consumption of buildings. Therefore, a novel energy consumption prediction model for chillers based on an improved support vector machine (ICA-DE-SVM) is proposed. The imperialist competitive algorithm (ICA) is used to optimize the penalty coefficient and kernel function width of SVM, greatly improving the generalization ability and prediction accuracy of the SVM model. The assimilation process is very important in ICA. Colonies of empires move randomly toward imperialists during the assimilation process in ICA, which decreases population diversity and can lead to premature convergence. Therefore, to create more new locations for colonies and increase population diversity, the idea of differential mutation proposed by differential evolution (DE) was applied to ICA. The established model was experimentally verified in an actual multi-chiller system in a building, and the results showed that the ICA-DE-SVM model could obtain good prediction results. Finally, the proposed model was compared with SVM model, PSO-SVM model, GA-SVM model, WOA-SVM model, and ICA-SVM model. With an MAPE of 0.6%, an MSE of 2.3, and an R2 of 0.9998, the findings demonstrate that the ICA-DE-SVM model has a greater prediction accuracy than the other models.
Goal-oriented requirement language model analysis using analytic hierarchy process
Authors: Sumesh Sreenithya , Krishna Aneesh , ITU-T R.Z.
Published: January 2023

We present the application of multi-objective optimisation analytic methodologies to goal models in this research, with the intention of providing various benefits beyond the initial modelling act. Optimisation analysis can be used by modellers to evaluate goal satisfaction, evaluate high-level design alternatives, aid analysts in deciding on high-level requirements and system design, verify the sanity of a model, and improve communication and learning. Goal model analysis may be done in a variety of methods, depending on the nature of the model and the study’s goal. In our work, we use the Goal-Oriented Requirement Language (GRL), which is part of the User Requirements Notation (URN), a new International Telecommunication Union (ITU) recommendation that offers the first standard goal-oriented language. Existing optimisation methods are geared towards maximising objective functions. On the other hand, real-world problems necessitate simultaneous optimisation of both maximising and minimising objective functions. This work explores a GRL model analysis that may accommodate the conflicting goals of various inter-dependent actors in a goal model using the Analytic Hierarchy Process (AHP). By evaluating the qualitative or quantitative satisfaction levels of the actors and intentional elements (e.g., objectives and tasks) that make up the model, we construct a multi-objective optimisation method for analysis using the GRL model. The proposed hybrid technique evaluates the contribution of alternatives to the accomplishment of top softgoals. It is then integrated with the top softgoals’ normalised relative priority values. The integration result may be utilised to assess multiple alternatives based on the requirements problem. Although the URN standard does not mandate a specific propagation algorithm, it does outline certain criteria for developing evaluation mechanisms. Case studies were used to assess the viability of the suggested approach in a simulated environment using JAVA Eclipse and IBM Cplex. The findings revealed that the proposed method can be used to analyse goals in goal models with opposing multi-objective functions.
The French paradox (1992-2022) - three decades of research on the cardioprotective properties of grape wine
Authors: Gawlik Maciej
Published: January 2023

30 lat temu epidemiolog francuski Serge Renaud wraz ze swoim współpracownikiem Michelem de Lorgerilem opublikowali w „The Lancet” artykuł fundujący nauce postulat „francuskiego paradoksu”. Mniejszą umieralność Francuzów z powodu arteriosklerozy naczyń wieńcowych (CHD) w stosunku do Brytyjczyków i Amerykanów przy podobnych wartościach czynników ryzyka CHD, przypisali zwiększonej i regularnej konsumpcji wina gronowego. Uruchomiony założycielską publikacją proces badań naukowych, mających na celu potwierdzenie lub obalenie zaskakującej hipotezy, doprowadził do dynamicznego rozwoju wiedzy na temat biologicznych właściwości wina gronowego i jego składników. Wśród nich największe zainteresowanie przypisano frakcji polifenolowej mieszczącej się w grupie mikroskładników wina. Dla wytypowanych polifenoli (m.in. rezweratrol, kwercetyna, (+)-katechina) wykazano korzystne działanie w obrębie równowagi wazodylatacyjnej śródbłonka naczyń, metabolizmu lipidów i układu krzepnięcia. Mimo tysięcy eksperymentów epidemiologicznych i laboratoryjnych do dziś nie udało się przesądzić o trafności postawionej hipotezy w zakresie umiarkowanej konsumpcji wina (20-30 g alkoholu/dzień). Wartością samą w sobie „francuskiego paradoksu” jest inspirowanie już dwóch pokoleń badaczy do wyjaśnienia obserwacji, poszerzające wiedzę m.in. w obszarze wpływu na zdrowie naturalnych składników diety. W pracy zaprezentowano rys historyczny okoliczności ogłoszenia „francuskiego paradoksu” oraz przedstawiono ewolucję poglądów naukowych na kontrowersyjną hipotezę. Podano również główne zarzuty sformułowane przeciwko wyjaśnieniu wskazującemu na wino gronowe jako przyczynę paradoksalnej obserwacji. Obejmują one m.in. twierdzenie, że autorzy hipotezy nie uwzględnili przewlekłego charakteru CHD i umieralność korelowali z bieżącymi wartościami czynników ryzyka zamiast z danymi z przeszłości. Część artykułu poświęcono omówieniu aktualnego stanu wiedzy oraz perspektyw dalszych badań i ewentualnemu wykorzystaniu wyników w obszarze zdrowia publicznego i farmacji.
A Case Study of Completely Buried Wind-Power Cable Detection Using 3D Acoustic Imaging
Authors: Ha Jiho , Shin Jungkyun
Published: January 2023

As offshore wind power is renewable energy produced through the installation and operation of large-scale offshore infrastructure, risk management is crucial in power platforms. Safety accidents caused by external factors during the operation of submarine power cables can lead to enormous costs, thus necessitating the monitoring of burial depth and route information of cables. In this study, we developed a 3D acoustic imaging method that obtains information on the route and depth of completely buried power cables. An acoustic source-based engineering ocean seismic 3D (EOS3D) system has been used to detect buried objects in the subsurface because conventional sonars, such as multi-beam echo sounder (MBES) and side-scan sonar (SSS), which are used to analyze seafloor characteristics, have limitations in detecting completely buried cables in the subsurface. Field data were obtained as 8-channel data using a chirp source (2–8 kHz) designed to obtain a 25 × 25 cm horizontal spatial resolution from real-time kinematic (RTK) positioning. The image stack method was proposed to effectively detect buried cables, with the vertical gradient analyzed using signals decomposed into representative bin sizes and low-mid-high-frequency components. The acoustic anomalies of buried objects, identified as export cables and protectors, were processed into images using the proposed image stack method and gradient analysis. This case study of buried wind power cables using 3D acoustic imaging could be utilized in burial assessment survey (BAS)-data acquisition, processing/analysis processes, and operation and management of buried cables.

Diabetes mellitus (DM) é um grupo heterogêneo de distúrbios metabólicos que resultam em hiperglicemia decorrente de defeitos na ação e/ou secreção da insulina, sendo possível encontrar na literatura diversas plantas com relato de atividade antidiabética, entre elas, as do genêro Bauhinia. Assim, o objetivo desse artigo foi abordar através da literatura as propriedades antidiabéticas das plantas medicinais do gênero Bauhinia, que são popularmente conhecidas como pata-de-vaca, unha-de-vaca, unha de boi ou bauínia. Dessa forma, foi realizado um levantamento bibliográfico nas bases de dados LILACS e PubMed/MEDLINE, que abrangeram publicações nacionais e internacionais, de 2000 a 2021, totalizando 20 artigos. Evidenciou-se através dos artigos que o gênero Bauhinia  seria coadjuvante à terapêutica do Diabetes mellitus, apresentando propriedades antidiabéticas, e que sua utilização auxilia no controle da patologia e prevenção de danos. Todavia, mesmo sendo uma planta vastamente utilizada pela população, ainda não foi regulamentada pela Agência Nacional de Vigilância Sanitária do Brasil e não apresenta indicação terapêutica, pois ainda se fazem necessários mais estudos que comprovem a sua segurança e eficácia, principalmente em humanos.
