Deconstructing Buddhist Extremism: Lessons from Sri Lanka
Authors: Ramakrishna Kumar
Published: November 2021

This article argues that it is not Buddhism, per se, but rather Buddhist extremism, that is responsible for violence against relevant out-groups. Moreover, it suggests that the causes of Buddhist extremism, rather than being determined solely by textual and scriptural justifications for out-group violence, are rooted instead in the intersection between social psychology and theology, rather than organically arising from the latter, per se. This article unpacks this argument by a deeper exploration of Theravada Buddhist extremism in Sri Lanka. It argues that religious extremism, including its Buddhist variant, is best understood as a fundamentalist belief system that justifies structural violence against relevant out-groups. A total of seven of the core characteristics of the religious extremist are identified and employed to better grasp how Buddhist extremism in Sri Lanka manifests itself on the ground. These are: the fixation with maintaining identity supremacy; in-group bias; out-group prejudice; emphasis on preserving in-group purity via avoidance of commingling with the out-group; low integrative complexity expressed in binary thinking; dangerous speech in both soft- and hard-modes; and finally, the quest for political power, by force if needed. Future research could, inter alia, explore how these seven characteristics also adequately describe other types of religious extremism.
Effect of Using Different Amounts of Multi-Temporal Data on the Accuracy: A Case of Land Cover Mapping of Parts of Africa Using FengYun-3C Data
Authors: Adugna Tesfaye , Xu Wenbo , Fan Jinlong
Published: November 2021

Regional or continental-scale land cover mapping requires various amounts of months of multi-temporal satellite data to pick phenological variation in vegetation, enhancing differentiability among surface cover types and improving accuracy. However, little has been addressed about the number of months/multi-temporal images needed to obtain the best result and the impact of using different amounts of these data on the accuracy of individual classes. This work aimed to analyze these effects by utilizing the various amounts of months of time series FengYun-3C (FY-3C) data within one year for land cover mapping of parts of Africa using a random forest classifier. The study area covers roughly one-third of Africa, including eastern, central, and northern parts of the continent. One-year FY-3C ten-day composite images consisting of eleven-band each with 1-km spatial resolution were divided into seven input datasets that comprise stacked images of 1-month, 3-month, 6-month, consecutive 9-month, 12-month, selected images from 12 months using band/feature importance, and selected 9-month. Comparisons of these datasets on independent test samples revealed that overall accuracy, kappa coefficient, and the accuracy of the individual classes generally increase significantly with increasing the number of data/months. However, the highest accuracy and kappa coefficient, 0.86 and 0.83, were obtained by processing selected 9-month imageries. The second maximum accuracy and kappa (0.85 and 0.82,) were found by manipulating 12-month scenes which are the same as the results obtained by applying feature reduction. Although 4% and 5% higher accuracy were achieved by manipulating 3-month and 6-month data relative to 1-month imageries, no variation of accuracy was observed between six- and nine-months of consecutive data, both yielding equal accuracy and kappa value (0.84 and 0.81) indicating redundancy of information. Overall, the high accuracy results show the feasibility of FY-3C data for land cover mapping of Africa.

Authors: Broß Cara , Enzingmüller Carolin , Parchmann Ilka , Schmidt Gerhard
Published: November 2021

A major challenge in modern society is the need to increase awareness and excitement with regard to science, technology, engineering and mathematics (STEM) and related careers directly or among peers and parents in order to attract future generations of scientists and engineers. The numbers of students aiming for an engineering degree are low compared to the options available and the workforce needed. This may, in part, be due to a traditional lack of instruction in this area in secondary school curricula. In this regard, STEM outreach programs can complement formal learning settings and help to promote engineering as well as science to school students. In a long-term outreach collaboration with scientists and engineers, we developed an outreach program in the field of magnetoelectric sensing that includes an out-of-school project day and various accompanying teaching materials. In this article, we motivate the relevance of the topic for educational outreach, share the rationales, objectives and aims, models and implementation strategies of our program and provide practical advice for those interested in outreach in the field of magnetoelectric sensing.
Fault Detection in the MSW Incineration Process Using Stochastic Configuration Networks and Case-Based Reasoning
Authors: Ding Chenxi , Yan Aijun
Published: November 2021

Fault detection in the waste incineration process depends on high-temperature image observation and the experience of field maintenance personnel, which is inefficient and can easily cause misjudgment of the fault. In this paper, a fault detection method is proposed by combining stochastic configuration networks (SCNs) and case-based reasoning (CBR). First, a learning pseudo metric method based on SCNs (SCN-LPM) is proposed by training SCN learning models using a training sample set and defined pseudo-metric criteria. Then, the SCN-LPM method is used for the case retrieval stage in CBR to construct the fault detection model based on SCN-CBR, and the structure, algorithmic implementation, and algorithmic steps are given. Finally, the performance is tested using historical data of the MSW incineration process, and the proposed method is compared with typical classification methods, such as a Back Propagation (BP) neural network, a support vector machine, and so on. The results show that this method can effectively improve the accuracy of fault detection and reduce the time complexity of the task and maintain a certain application value.

Published: November 2021

Coverage path planning (CPP) is a field of study which objective is to find a path that covers every point of a certain area of interest. Recently, the use of Unmanned Aerial Vehicles (UAVs) has become more proficient in various applications such as surveillance, terrain coverage, mapping, natural disaster tracking, transport, and others. The aim of this paper is to design efficient coverage path planning collision-avoidance capable algorithms for single or multi UAV systems in cluttered urban environments. Two algorithms are developed and explored: one of them plans paths to cover a target zone delimited by a given perimeter with predefined coverage height and bandwidth, using a boustrophedon flight pattern, while the other proposed algorithm follows a set of predefined viewpoints, calculating a smooth path that ensures that the UAVs pass over the objectives. Both algorithms have been developed for a scalable number of UAVs, which fly in a triangular deformable leader-follower formation with the leader at its front. In the case of an even number of UAVs, there is no leader at the front of the formation and a virtual leader is used to plan the paths of the followers. The presented algorithms also have collision avoidance capabilities, powered by the Fast Marching Square algorithm. These algorithms are tested in various simulated urban and cluttered environments, and they prove capable of providing safe and smooth paths for the UAV formation in urban environments.
TSInsight: A Local-Global Attribution Framework for Interpretability in Time Series Data
Authors: Siddiqui Shoaib Ahmed , Mercier Dominique , Dengel Andreas , Ahmed Sheraz
Published: November 2021

With the rise in the employment of deep learning methods in safety-critical scenarios, interpretability is more essential than ever before. Although many different directions regarding interpretability have been explored for visual modalities, time series data has been neglected, with only a handful of methods tested due to their poor intelligibility. We approach the problem of interpretability in a novel way by proposing TSInsight, where we attach an auto-encoder to the classifier with a sparsity-inducing norm on its output and fine-tune it based on the gradients from the classifier and a reconstruction penalty. TSInsight learns to preserve features that are important for prediction by the classifier and suppresses those that are irrelevant, i.e., serves as a feature attribution method to boost the interpretability. In contrast to most other attribution frameworks, TSInsight is capable of generating both instance-based and model-based explanations. We evaluated TSInsight along with nine other commonly used attribution methods on eight different time series datasets to validate its efficacy. The evaluation results show that TSInsight naturally achieves output space contraction; therefore, it is an effective tool for the interpretability of deep time series models.
Towards a Mobile Gait Analysis for Patients with a Spinal Cord Injury: A Robust Algorithm Validated for Slow Walking Speeds
Authors: Werner Charlotte , Awai Easthope Chris , Curt Armin , Demkó László
Published: November 2021

Spinal cord injury (SCI) patients suffer from diverse gait deficits depending on the severity of their injury. Gait assessments can objectively track the progress during rehabilitation and support clinical decision making, but a comprehensive gait analysis requires far more complex setups and time-consuming protocols that are not feasible in the daily clinical routine. As using inertial sensors for mobile gait analysis has started to gain ground, this work aimed to develop a sensor-based gait analysis for the specific population of SCI patients that measures the spatio-temporal parameters of typical gait laboratories for day-to-day clinical applications. The proposed algorithm uses shank-mounted inertial sensors and personalized thresholds to detect steps and gait events according to the individual gait profiles. The method was validated in nine SCI patients and 17 healthy controls walking on an instrumented treadmill while wearing reflective markers for motion capture used as a gold standard. The sensor-based algorithm (i) performed similarly well for the two cohorts and (ii) is robust enough to cover the diverse gait deficits of SCI patients, from slow (0.3 m/s) to preferred walking speeds.

Published: November 2021

Epidemiological trends over the past decade show a significant worldwide increase in the burden of chronic diseases. At the same time, the human resources of health care are becoming increasingly scarce and expensive. One of the management concepts that can help in solving this problem is business process management (BPM). The results of research conducted in the healthcare sector thus far prove that BPM is an effective tool for optimizing clinical processes, as it allows for the ongoing automatic tracking of key health parameters of an individual patient without the need to involve medical personnel. The aim of this article is to present and evaluate the redesign of diagnostic and therapeutic processes enabling the patient-centric organization of therapy thanks to the use of new telemedicine techniques and elements of hyperautomation. By using an illustrative case study of one of the most common chronic diseases, Chronic Obstructive Pulmonary Disease (COPD), we discuss the use of clinical pathways (CPs) prepared on the basis of the current version of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) as a communication tool between healthcare professionals, the patient and his or her caregivers, as well as the method of identifying and verifying new knowledge generated on an ongoing basis in diagnostic and therapeutic processes. We also show how conducting comprehensive, patient-focused primary health care relieves the health care system, and at the same time, thanks to the use of patient engagement and elements of artificial intelligence (predictive analyses), reduces the significant clinical risk of therapy.

Published: November 2021

Spatial orientation and navigation depend primarily on vision. Blind people lack this critical source of information. To facilitate wayfinding and to increase the feeling of safety for these people, the “feelSpace belt” was developed. The belt signals magnetic north as a fixed reference frame via vibrotactile stimulation. This study investigates the effect of the belt on typical orientation and navigation tasks and evaluates the emotional impact. Eleven blind subjects wore the belt daily for seven weeks. Before, during and after the study period, they filled in questionnaires to document their experiences. A small sub-group of the subjects took part in behavioural experiments before and after four weeks of training, i.e., a straight-line walking task to evaluate the belt’s effect on keeping a straight heading, an angular rotation task to examine effects on egocentric orientation, and a triangle completion navigation task to test the ability to take shortcuts. The belt reduced subjective discomfort and increased confidence during navigation. Additionally, the participants felt safer wearing the belt in various outdoor situations. Furthermore, the behavioural tasks point towards an intuitive comprehension of the belt. Altogether, the blind participants benefited from the vibrotactile belt as an assistive technology in challenging everyday situations.
A Simplified Method for Considering Achilles Tendon Curvature in the Assessment of Tendon Elongation
Authors: Kharazi Mohamadreza , Theodorakis Christos , Mersmann Falk , Arampatzis Adamantios , Bohm Sebastian
Published: November 2021

The consideration of the Achilles tendon (AT) curvature is crucial for the precise determination of AT length and strain. We previously established an ultrasound-kinematic-based method to quantify the curvature, using a line of reflective foil skin markers covering the AT from origin to insertion. The current study aimed to simplify the method by reducing the number of markers while maintaining high accuracy. Eleven participants walked (1.4 m/s) and ran (2.5, 3.5 m/s) on a treadmill, and the AT curvature was quantified using reflective foil markers aligned with the AT between the origin on the gastrocnemius myotendinous-junction (tracked by ultrasound) and a marker on the calcaneal insertion. Foil markers were then systematically removed, and the introduced error on the assessment of AT length and strain was calculated. We found a significant main effect of marker number on the measurement error of AT length and strain (p<0.001). Using more than 30% of the full marker-set for walking and 50% for running, the R2 of the AT length error saturated, corresponding to average errors of <0.1 mm and <0.15% strain. Therefore, a substantially reduced marker-set, associated with a marginal error, can be recommended for considering the AT curvature in the determination of AT length and strain.
Water-Saving Irrigation Promotion and Food Security: A Study for China
Authors: Yang Rui , Gao Qijie
Published: November 2021

In response to water scarcity and food security, most governments in the world have adopted water-saving irrigation promotion policies by increasing the water-saving irrigation area. Many researches focus on water scarcity, but there is a lack of research on the food security effects of water-saving irrigation policies. A two-way fixed effect model was used to identify the effect of water-saving irrigation area on the production of food crops with panel data of 31 Chinese provinces from 2000 to 2019. The study shows: First, water-saving irrigation area not only can save agricultural water use, but also has a significant positive effect on production of food crops; Second, water-saving irrigation area affects production of food crops through agricultural input factors, such as sown area, chemical fertilizer, and mechanized power; Third, there is heterogeneity in the effect of water-saving irrigation area on production of food crops, in which water-saving irrigation area has a greater impact on production of food crops in areas where there is less rainfall, or lower water-saving irrigation rate. Therefore, the water-saving irrigation promotion has a significant role in promoting China’s production of food crops and has made a certain contribution to ensuring food security.

Published: November 2021

Achieving high levels of vaccination coverage against COVID-19 may be hindered by vaccine hesitancy. We quantified over time the prevalence of COVID-19 vaccine hesitancy among university students, investigated its determinants, and analyzed student attitudes, risk perceptions and compliance with preventive measures. The survey was administered online from 1 March to 30 June 2021. A multivariable logistic regression model was built to identify predictors of hesitancy. Overall, we collected 5369 questionnaires that were grouped into three survey periods (March, April–May, and May–June). The response rate ranged from 81.2% to 76.4%, whereas vaccine hesitancy ranged from 22% to 29%. Multivariable analysis showed that April–May participants had higher odds of hesitancy than March respondents. Other positive predictors were being male, not being a healthcare student, having a lower academic level, and not disclosing a political position. Conversely, higher levels of perceived COVID-19 severity, concern for the emergency, confidence in vaccine safety and effectiveness, and self-reported adherence to mask wearing indoors and outdoors were negatively associated with hesitancy. We found that vaccine hesitancy changed over time and in relation to several factors. Strategies aimed at increasing the students’ awareness and engagement, restoring confidence in health authorities, and limiting disinformation around the vaccines should be devised.

По результатам взвешиваний определен абсолютный прирост, абсолютный среднесуточный прирост живой массы, относительная скорость роста. В период от рождения до 7-месячного возраста, который совпал с летним периодом пастбищного сезона, живая масса бычков увеличилась на 131,4 кг, а телок — на 120,2 кг. Интенсивность роста составила соответственно 625,7 и 572,4 г, что свидетельствует о достаточно хорошей молочности маток. В зимний период (возраст молодняка — от 7 до 12 мес) интенсивность роста резко снизилась: живая масса бычков и телочек составила всего 161,3 и 143,7 кг, со среднесуточными приростами — 94 и 58 г соответственно. С началом вегетации пастбищных растений приросты молодняка по сравнению с зимним периодом резко увеличились. В возрасте от 12 до 18 мес они были равны: 476 г — у бычков и 439 г — у телочек. Общий прирост живой массы бычков за этот период составил 86 кг, у телочек — 79 кг. Полученные данные свидетельствуют о достаточно хорошем развитии молодняка яков алтайской популяции.

The growth rate of young yaks of the Altai population, characterized by vigorous growth, was investigated. The growth dynamics of young yaks was studied by determining their live weight at different age periods – at birth and at the age of 7, 12, 18 months. According to the weighing results, the absolute gain, the absolute average daily gain in live weight, and the relative growth rate were determined. In the period from birth to 7 months of age, which coincided with the summer months of the pasture season, the live weight of bull calves increased by 131.4, and heifers — by 120.2 kg, i.e., the growth rate was 625.7 and 572.4 g, respectively, which characterizes a fairly good milk yield of cows. In the winter period (age from 7 to 12 months), the growth rate decreased sharply: the live weight of calves and calves was only 161.3 kg and 143.7 kg, with average daily gains of 94 and 58g, respectively. Subsequently, with the beginning of the growing season of pasture plants, the weight gain of young animals in comparison with the winter period increased sharply. At the age of 12 to 18 months they were equal: 476 g-for steers and 439 g-for heifers. The total increase in live weight of calves during this period was 86 kg, of heifers — 79 kg. The data obtained indicate a fairly good development of young yaks of the Altai population.

Genetic Algorithms as Computational Methods for Finite-Dimensional Optimization
Authors: Gulayeva Nataliya , Shylo Volodymyr , Glybovets Mykola
Published: November 2021

Introduction. As early as 1744, the great Leonhard Euler noted that nothing at all took place in the universe in which some rule of maximum or minimum did not appear [12]. Great many today’s scientific and engineering problems faced by humankind are of optimization nature. There exist many different methods developed to solve optimization problems, the number of these methods is estimated to be in the hundreds and continues to grow. A number of approaches to classify optimization methods based on various criteria (e.g. the type of optimization strategy or the type of solution obtained) are proposed, narrower classifications of methods solving specific types of optimization problems (e.g. combinatorial optimization problems or nonlinear programming problems) are also in use. Total number of known optimization method classes amounts to several hundreds. At the same time, methods falling into classes far from each other may often have many common properties and can be reduced to each other by rethinking certain characteristics. In view of the above, the pressing task of the modern science is to develop a general approach to classify optimization methods based on the disclosure of the involved search strategy basic principles, and to systematize existing optimization methods.
The purpose is to show that genetic algorithms, usually classified as metaheuristic, population-based, simulation, etc., are inherently the stochastic numerical methods of direct search.
Results. Alternative statements of optimization problem are given. An overview of existing classifications of optimization problems and basic methods to solve them is provided. The heart of optimization method classification into symbolic (analytical) and numerical ones is described. It is shown that a genetic algorithm scheme can be represented as a scheme of numerical method of direct search. A method to reduce a given optimization problem to a problem solvable by a genetic algorithm is described, and the class of problems that can be solved by genetic algorithms is outlined.
Conclusions. Taking into account the existence of a great number of methods solving optimization problems and approaches to classify them it is necessary to work out a unified approach for optimization method classification and systematization. Reducing the class of genetic algorithms to numerical methods of direct search is the first step in this direction. Keywords: mathematical programming problem, unconstrained optimization problem, constrained optimization problem, multimodal optimization problem, numerical methods, genetic algorithms, metaheuristic algorithms.

To know the comparison of knowledge using the Independent t-test and the attitude using the Chi-square test.

Results: the results of the independent t-test were used to find out the comparison between the leaflet group and the PowerPoint group, the p-value was 0.206, and the chi-square test between the leaflet group and the PowerPoint group obtained a p-value of 1,000.

Conclusion: there was no difference in the effect of using leaflets compared to power points on the knowledge and attitudes of pregnant women about Hepatitis B in UPTD Puskesmas Kedokan Bunder Indramayu Regency in 2020.

Introduction: To determine the difference in the quality of life and cognitive function in patients with and without AMD.

Methods: This research is an observational analytic study, a prospective cross sectional study in the polyclinic of RSUP Sanglah, Denpasar.

Result: Study samples’s total are 66 people selected by consecutive sampling with 33 people in the group with AMD, and 33 people in the group without AMD. The results of the study showed the average age of the group with AMD 68 years and the group without AMD 67 years old. Most of the male sex and residence in denpasar in both groups. Most AMD with the wet type by 60.6 %. On the measurement of quality of life, it showed  decreasing in all subscale in the group with AMD compared to the group without AMD with total average 27.2 % and also decreasing in cognitive function measured by MMSE in the group of AMD compared to the group of non – AMD with 6.8%, even though the MMSE score of the groups are within normal limits. All these things stated significant differences (p<0.05) statistically.

Conclusion: There are decreasing quality of life and cognitive function in AMD groupd compared to Non-AMD group which is needed more treatment and screening in the future.
Precedent-Based Learning: An Approach for Studio Pedagogy in the Early Years
Authors:   Carnegie Mellon University, Akin Ömer
Published: November 2021

Precedent-Based learning is related to a very old method of teaching, particularly in the studio setting. Usually it takes the form of precedent analysis. An empirical study was conducted in order to better understand how experienced designers use precedents in the course of a brief design session. Normative theories of learning suggest that success is most likely to be achieved when students learn (1) the principles governing events or phenomenon in a discipline, and (2) ways of applying these principles to specific situations to solve problems of various kinds. We call this the didactic method. In the didactic approach there is a systematic representation of the fundamental principles of knowledge that identify a specific domain upon which a corpus of applications or problem-solving skills can be constructed. In fields that deal with professional practice, for example design, instruction appears to deviate from this pattern in significant ways. Students are rarely given robust principles (ones that hold in different contexts), let alone immutable ones, upon which they can construct designs that can be judged unequivocally or without error. Instead they are given plenty of precedents from which to learn a variety of heuristics. This type of knowledge is fundamentally tacit, situated in a context of extra-domain information, and involving pedagogy that is principally experiential. In architectural curricula, the experiential approach to learning is omnipresent. Descriptions of design instruction, or for that matter, architectural curricula within which such instruction is found, are invariably of an indirect kind. They describe the stylistic or formal attributes of the architecture that is promoted by the particular pedagogy in order to explain its characteristics, principles and techniques [5,7,8,11,19].
The Practicing Academic: Insights of South African Architectural Education

Architectural education, in the past had a grounding in a strict apprentice or pupillage method of training architects. The apprentice was someone who worked or trained under a master that transferred skill through a “hands on” approach. Architecture was regarded as one of the arts and there was no formal training to qualify one as an architect. It was through the acclaimed Vitruvius that the architectural profession was born. Vitruvius had published “Ten Books on Architecture” that led to an attempt to summarize professional knowledge of architecture and in doing so became the first recognizable architect. The architectural profession spread throughout Europe in the mid-16th century and the builder and architect became two distinct characters. Although architecture had become a profession, it wasn’t up until the late 17th century that architecture became an academic pursuit through an institutionalized educational system known as École des Beaux Arts, however the pursuit of a strict academic scholar was not the focus. At the beginning of the 1800’s, The University of Berlin in Germany forged the fundamental research and scholarly pursuit. Architecture, like the professions of medicine, law etc. became a system of academic pursuit where professors concentrated deeply on academics first and professional work second. It is through the lens of history we can decipher how architecture became an academic discipline almost de-voiding it of its vocational nature. In its current standing, various universities place a high emphasis on research output from their academic staff. Presently, architecture schools in South Africa recruit lecturers on their academic profiles, rather than their vocational experience. The approach of which has devalued the input of industry into education. It has been noted that there has been an increase in an academic pursuit rather than a professional one for the lecturers that teach architecture. This research explores the views of academics on architectural education, teaching methods and the importance of practice at South African universities. The authors of this research provide an auto-ethnographic insight into their invaluable experience of being academics at two large Universities in South Africa and concurrently run successful practices. The research makes use of a mixed method approach of secondary data from literature and semi-structured interviews posed to academics. Initial findings reveal that academics are pushing the industry to play a part in the education of architects; however, the extent must be determined. If industry plays a role in the education of architects, what factors are considered and how does this inter-twine with the academic nature of training? What strategies are academics employing to make sure students are vocationally well trained and academically capable? Another important question to ask is what qualities make an academic architect in the 21st century?
From Representation to Infrastructure: The Case for Design Advocacy through Drawing
Authors:   American University of Beirut, Aramouny Carla
Published: November 2021

When teaching design and architecture in oscillation between practice and academia, we are inescapably bound by questions of context; our environment reflects greatly on us and our perception and forms the basis of our design approach and rhetoric. In teaching, we attempt to engage students in reflecting on, observing and rethinking their contexts. We push them to reflect on new potentials, to re-imagine what is usually widely established. We allow them to create opportunities for new perspectives, and to ponder upon the potential of “other” possibilities that may exist. In Lebanon, a country with end-less problems and infrastructural deterioration, such questioning is unavoidable and becomes crucial to pursue at an academic level, where reality and practice fail to proceed. The academic endeavor takes on the role of the provocateur, the advocator for change, projecting forward with a new imaginary. On the other hand, drawing, architecture’s most powerful medium, has resurged today as an essential thinking tool, able to convey ideas and suggest aspirations. Its role has progressed beyond the limits of representation, becoming fundamental for reflection, conceptualization and advocacy. Its power lies in its recurrent ability to convey meaning visually, which is universally understood.My teaching trajectories try to bring these two together: Drawing and reimagining context. This is especially distilled in a seminar course I teach at the American University of Beirut, titled “Micro/ Macro Infrastructures” that builds upon the potential of architecture representation with speculative proposals for local infrastructural systems, presented through the medium of a pamphlet and articulated to advocate for change through design.
