FUZZY REGULATOR OF THE ROD SUPPLY SYSTEM OF ARDUINO-BASED CROSS-WEDGE ROLLING MILL IN LABVIEW ENVIRONMENT
Authors: Bagriy V. , Voloshyn R. , Voloshina K.
Published: June 2022

The main purpose of scientific work is to develop a regulator based on fuzzy logic for an electronic control system for the supply of bar billets in automated cross-wedge rolling complexes.

Cross-wedge rolling belongs to the advanced energy-saving technologies where technological processes based on metal cutting are replaced by economic processes of plastic forming of details. The analysis showed that coefficient increase of metal utilization requires loss decrease arising from the supply inaccuracy of the bar workpiece to the length of the part. The task is to reproduce the given law of motion of the actuator, i.e. to ensure maximum speed, smooth acceleration and braking with the possibility of a shockless stop at the end of the stroke. The solution of this problem is proposed to be carried out by entering  the fuzzy control unit into the structure of the system for controlling the supply..

The hardware basis of the control system in this work is the Arduino hardware and software complex based on the Atmel AVR microcontroller. The software model of the control system is developed in the graphical programming environment LabVIEW, which is widely used as a standard tool for data collection and control of devices in industry, education and research laboratories. The construction of a fuzzy regulator and its implementation are considered using Fuzzy Logic Designer.

On the basis of systematized knowledge about the object of research, its characteristics and features, linguistic input and output variables were selected, as well as membership functions and a fuzzy production model of knowledge was formulated. The configuration of the control system depends on the number of controlled outputs and controlled input data and in this case the MISO information structure is applied. The paper presents the front panel of the virtual device developed by LabVIEW, which is designed to display information about the current state of the system. The purpose of the developed fuzzy regulator model is to output the value of the initial air pressure in the cavity of the actuating pneumatic cylinder, which will create an air cushion in the process of advancing the piston, which has properties similar to those of a normal spring. Smooth stopping of the piston is provided by the coordinated choice of rigidity of a pneumatic spring taking into account length of a detail and weight of a rod and allows us to reduce kinetic energy in an end point of positioning that increases accuracy of supply.

The analysis of research results confirmed the efficiency and adequacy of the  model used and the developed set of operation  rules of the fuzzy regulator. Testing of the control system on parts of different lengths confirmed a reduction in total losses and an increase in the utilization of the metal.
MODEL OF ROLLING RODS IN THE ROLL PASS OF THE OVAL-ROUND

Published: June 2022

For modern high-speed rolling mills, stable and efficient operation is possible only with the use of automatic process control systems. Such systems involve the use of certain process models, both for control and technology development. Therefore, research aimed at improving existing models of the process of rolling rods and developing new ones remains relevant.

The aim is to improve the model of the process of rolling rods of round cross-section using a system of passes "oval-round", suitable for the development of technology (determining the size of pass and power parameters) and as software for automatic process control systems.

A characteristic difference of the proposed improved model is the application of the condition of volume constancy to determine not only the speed but also the deformation parameters of rolling. Features of the model also include the appointment of the ratio of the axes of oval passes and the use of the rate of mismatch in the interstand spaces to control and minimize tension.The sequence of calculations in the model includes an iterative procedure with three mandatory approximations, which involves adjusting the coefficients of elongation using the condition of constant volume, and adjusting the size of the workpieces using speed mismatch as a factor characterizing the corresponding tension or compressive.

The model uses known expression and geometric relationships, the combination and sequence of which provides the definition of technological parameters and sizes of roll passes with the required accuracy. The program can be implemented in various forms depending on the needs, from the most common applications to environments of professional computer systems. The model can be used as a basis for the development of systems for automatic control of the rolling process for the conditions of the existing mills.

Published: June 2022

Given user choices and the commercial offerings of internet providers, WhatsApp has increasingly become established as a new standard for communication by audio, image, and text. This paper explores the role of misinformation during the Covid-19 pandemic by using content disseminated through WhatsApp, thereby making three main contributions: a discussion about the potential shift toward nontextual and nonvisual forms of misinformation; the new social role of audio, namely related to the critique of policies and political actors during the early stage of the Covid-19 pandemic; and the questioning of the First Draft News disinformation conceptual model by proposing a complementary approach that focuses only on factuality. Conclusions were drawn after conducting a content analysis of 988 units of Covid-19-related audio files, images, videos, and texts shared via WhatsApp during the early stage of the pandemic. A typology was identified to address distinct claims that focus on five different topics (society, policy and politics, health science, pandemic, and other), as well as audio messaging trending as a novel format for spreading misinformation. The results help us to contextualize and discuss a potential shift toward nontextual and nonvisual forms of misinformation, reflecting the increasing adoption of the audio format among WhatsApp users and making WhatsApp a fertile environment for the circulation and dissemination of misinformation regarding Covid-19-related themes. In a society characterized by the rapid consumption of information, the idea that content must have a degree of falsehood to mislead is an indicator of the distance between theoretical models and social reality. This indicator is important to identify true content as potential misinformation on the basis of its factuality.
Romantik İlişkilerde Modern Engel: Partner Sosyotelizmi (Phubbing) Üzerine Bir Derleme
Authors: Parmaksız İzzet
Published: June 2022

Bu çalışmanın amacı sosyotelizm davranışının çift ilişkilerindeki yansımasını alan yazın derlemesiyle ortaya koymaktır. Sosyotelizmin çift ilişkilerine yansıması ise “partner sosyotelizm” olarak isimlendirilmektedir. Partner sosyotelizm kavramı romantik ilişkilerde çiftlerin birlikteyken karşılıklı ilgi göstermeleri gerektiğinde bunun yerine cep telefonlarıyla ilgilenmeleri ve muhatabını görmezden gelmeleridir. Bu davranışsal problem romantik ilişkilerde gittikçe büyük bir sorun haline dönüşerek çift anlaşmazlıklarının önemli bir nedeni olarak belirmektedir. Bu davranışı sergileyen birey partneriyle birlikteyken sık sık cep telefonunu kontrol eder. Telefonları her zaman görebilecekleri bir yerdedir ya da telefonunu ellerinde tutarlar. Ayrıca çiftler arasında kıskançlık kaynaklı problemlere de neden olur. Bu konuda problem yaşayan çiftlerin ilişkilerinden sağladıkları doyum da zamanla azalabilmektedir. Ayrıca yaşanan gerginlikler bireylerin iyilik halini de negatif etkilemektedir. Ortaya çıkardığı olumsuz sonuçlar partner sosyotelizmin ciddi bir problem olarak ele alınması ve her bir bireyin kişisel sorumluluk alması gerektiğini göstermektedir. Telefon ve internet kullanımını hayatımızdan çıkaramasak da bu teknolojileri nasıl doğru kullanacağımızın bilincinde olmak gerekiyor. Ayrıca olumsuz etkilerinden dolayı telefon kullanım alışkanlıkları ve ortaya çıkardığı sosyal sorunlarla ilgili farkındalık oluşturulmalıdır. Aile dinamiklerini de etkileyen bu problemin çiftler tarafından görmezden gelinmemesi gereken bir problem olarak da algılanması gerekmektedir. Oluşan bu farkındalık çift ilişkilerinde yaşanabilecek olumsuzlukların önüne geçebileceği gibi bu yanlış kullanımın ortaya çıkarabileceği diğer riskleri de azaltabilecektir. Böylelikle hayatımızın bir parçası haline gelen ve kullanmanın zorunlu hale geldiği telefonlarımız sorun oluşturmayan bir boyuta taşınabilir.

Şiddet dediğimiz kavram, özellikle günümüzde kişisel, sosyal ve eğitsel alanlarda ciddi bir problem hâlini almış bulunmaktadır. Şiddetin kişilere ve kurumlara zarar verdiği açık bir olgudur. Bu noktadan bakıldığından, özellikle eğitim camiasına etkileri ve yankıları hatırı sayılır derecede büyük olmaktadır. Şiddet, yazılı, sözlü ve görsel basında özellikle adından sıkça söz ettirerek, ülke çapında üzücü olaylara sebep olan karanlık bir olgudur. Bu olguyu değerlendirirken eğitim alanına özellikle vurgu yapmakta fayda bulunmaktadır. Nitekim eğitim sistemi içerisinde ve özellikle okullarda şiddet olayları sıklıkla yaşanmakta ve hem bireylerin hem de kurumların işleyişinde ciddi aksaklıklara sebep olabilmektedir. Okullarda yaşanan şiddet olayları denildiğinde genellikle idareci ya da eğitimci tarafında öğrenciye yönelik ya da öğrencilerin arasında cereyan eden şiddet anlaşılmakta ve tek taraflı bir değerlendirme göze çarpmaktadır. Alanyazında da öğrenciye yönelik şiddet konusunda yapılan çalışmalar yoğunluk kazanırken, idarecilere ve öğretmenlere yönelik gerçekleştirilen şiddet eylemleri kendine hak ettiğinden daha az yer bulmaktadır. Eğitim sisteminin taşıyıcısı olan öğretmenler, gerek öğrenciler, gerek veliler ve gerekse meslektaşları tarafından şiddete maruz kalabilmektedir. Maruz kaldıkları bu şiddetin, hem bireysel hem de toplumsal bazda iş ve meslek hayatlarına hem de kişisel yaşantılarına bir takım etkileri olmaktadır. Bu nedenle bu çalışmanın amacı, öğretmenlere yönelik gerçekleştirilen şiddet davranışları, şiddete sebep olabilen risk faktörleri, şiddetin öğretmenler üzerindeki etkileri ile ilgili yapılan çalışmalardan elde edilen nitel ve nicel verilerden hareketle öğretmene şiddeti tüm yönleriyle tartışmak ve bu tartışmalar ışığında şiddete çözüm önerileri sunmaktır.

When Food Waste Goes to Work
Authors: Alexander Kelly
Published: June 2022

English Abstract:
Food waste is embroiled in a wide array of social efforts and actions in the contemporary EU. This article considers one site in the EU’s capital where surplus supermarket food that is no longer sellable but is still edible is being used to fuel a job training programme. It argues that, rather than understanding the state’s role in this process as a purely neoliberal tactic or as a capitalist profit-driven action, the repurposing of discarded food in order to create job opportunities and feed new populations has moral contours and enables specific forms of care.
Evaluating the Security Posture and Protection of Critical Assets of Industrial Control Systems in Zambia
Authors: Phiri Lukumba , Tembo Simon
Published: June 2022

The number of successful attacks on vital infrastructure has increased, as has the sophistication of the attacks. Many cybersecurity strategies include traditional best practices, but they frequently overlook organizational circumstances and unique critical infrastructure protection requirements. The goal of this qualitative multiple case research was to look into the cybersecurity tactics employed by IT managers and compliance officers to protect critical infrastructure from cyber threats. The participants in this study were IT managers and compliance officials from four Zambian case organizations. The conceptual framework was based on the routine activity theory published by criminologists Cohen and Felson in 1979. Interviews with two IT managers, three compliance officers, and 25 papers relating to cybersecurity and policy governance were used to gather data. Four significant themes emerged from data triangulation: the need for a robust worker training program, prioritizing infrastructure resiliency, the importance of security awareness, and the importance of organizational leadership support and investment. This research uncovered essential tactics that can help OT and compliance professionals enhance their cybersecurity strategy, which can help reduce successful assaults on critical infrastructure. The study findings will contribute to positive social change through an exploration and contextual analysis of cybersecurity strategy with situational awareness of OT practices to enhance cyber threat mitigation and inform business processes.
Evaluation of Petroleum Source Rock Using Well Logs in the Niger Delta Region of Nigeria
Authors: CHIGBO A WALIEZI , VICTOR I OKPOR , UDOM G. J , ADAORA B DOUGLAS
Published: June 2022

Petroleum source rock potential evaluation was carried out on eight wells of the Niger Delta’s Agbada Formation by assessing some source parameters from well logs and through well logs analysis based on organic matter effect and relationship on and with well logs. Source rock determinant parameters such as volume of shale (Vsh), total organic content (TOC), and amount of generated hydrocarbon (S2) was derived from well logs following established organic matter effects on well logs using Schlumberger's Techlog 2015 software, while hydrogen index (HI) was calculated using known values of TOC and S2 respectively. Well log data used for the analysis includes GR log, resistivity, sonic and Density logs. Apart from deriving source rock parameters, the well logs were also used to identify, quantify and somewhat determine mature zones of source rock intervals by correlation with TOC, S2, and HI source parameters respectively, Therefore, a source interval criterion composing of high GR log, high resistivity, high sonic and low-Density was developed alongside source rock parameters. Results of the analysis in the area show poor to fair source rock quality rating in terms of TOC, and insufficient source rock thickness fit for sustaining a world-class petroleum province like the ND petroleum province and further depicting that the Agbada FM may not be the principal source rock of the area. It is, therefore, recommended that more elaborate studies covering greater depths of the Agbada FM be carried out in other to properly represent the true source quality of the area.

The sudden calls for the end of fossil fuel production as a source of energy inspired this research. This study attempts to understand if these calls are due to “cartelization by political bodies” as described by Libecap, in 1972, promotion of self-benefits, or genuine calls based on disastrous impacts of global warming and general climate changes. Alternative energy sources and their present sustainability will be examined, policies affecting fossil fuels over time will be identified, the effects of these global and national policies, the politics behind calls and perspectives from various continents will be discussed, the lowest and highest GHG emitters will be identified, and recommendations will be made on the best course of action based on reviews and findings from around the world. Furthermore, this study understands that the world is a global village and considered the effect of climate change as a global challenge, however, its arguments and suggestion were made by critical analysis of the causation, major beneficiaries of policies, effects on countries dependent on fossil fuels, responses towards the effect of emission, and impact of climate change.
Novel MRI-based vertebral bone quality score as a predictor of cage subsidence following transforaminal lumbar interbody fusion

Published: June 2022

OBJECTIVE

Decreased bone mineral density as measured by dual-energy x-ray absorptiometry (DEXA) has been reported to be associated with cage subsidence following transforaminal lumbar interbody fusion (TLIF). However, DEXA is not often available or routinely performed before surgery. A novel MRI-based vertebral bone quality (VBQ) score has been developed and reported to be correlated with DEXA T-scores. The authors investigated the ability of the VBQ score to predict cage subsidence and other risk factors associated with this complication.

METHODS

In this retrospective study, the authors reviewed the records of patients who had undergone single-level TLIF from March 2014 to October 2015 and had a follow-up of more than 2 years. Cage subsidence was measured as postoperative disc height loss and was graded according to the system proposed by Marchi et al. The MRI-based VBQ score was measured on T1-weighted images. Univariable analysis and multivariable binary logistic regression analysis were performed. Ad hoc analysis with receiver operating characteristic curve analysis was performed to assess the predictive ability of the significant continuous variables. Additional analyses were used to determine the correlations between the VBQ score and T-scores and between the significant continuous variables and the amount of cage subsidence.

RESULTS

Among 242 patients eligible for study inclusion, 111 (45.87%) had cage subsidence after the index operation. Multivariable logistic regression analyses demonstrated that an increased VBQ score (OR 14.615 ± 0.377, p < 0.001), decreased depth ratio (OR 0.011 ± 1.796, p = 0.013), and the use of kidney-shaped cages instead of bullet-shaped cages (OR 2.766 ± 0.358, p = 0.008) were associated with increased cage subsidence. The VBQ score was shown to significantly predict cage subsidence with an accuracy of 85.6%. The VBQ score was found to be moderately correlated with DEXA T-scores of the total hip (r = −0.540, p < 0.001) and the lumbar spine (r = −0.546, p < 0.001). The amount of cage subsidence was moderately correlated with the VBQ score (r = 0.512, p < 0.001).

CONCLUSIONS

Increased VBQ scores, posteriorly placed cages, and kidney-shaped cages were risk factors for cage subsidence. The VBQ score was shown to be a good predictor of cage subsidence, was moderately correlated with DEXA T-scores for the total hip and lumbar spine, and also had a moderate correlation with the amount of cage subsidence.

OBJECTIVE

Excision of intracranial meningiomas often requires resection or coagulation of the dura mater. The choice of dural closure technique is individualized and based on surgeon preference. The objective of this study was to determine outcomes following various dural closure techniques for supratentorial meningiomas.

METHODS

A retrospective, single-center cohort study was performed for patients who underwent excision of supratentorial meningiomas from 2000 to 2019. Outcomes including operative time, postoperative in-hospital complications, readmission, causes of readmission including surgical site infection, pseudomeningocele, need for shunt surgery, and imaging appearance of pseudomeningocele on long-term follow-up imaging were compared. Univariate and multivariable analyses were conducted.

RESULTS

A total of 353 patients who had complete clinical and operative data available for review were included. Of these patients, 227 (64.3%) had nonsutured dural graft reconstruction and 126 (35.7%) had sutured dural repair, including primary closure, artificial dura, or pericranial graft. There was significant variability in using nonsutured dural reconstruction compared with sutured dural repair technique among surgeons (p < 0.001). Tumors with sagittal sinus involvement were more likely to undergo nonsutured closure (n = 79, 34.8%) than dural repair (n = 26, 20.6%) (p = 0.003). There were no other differences in preoperative imaging findings or WHO grade. Frequency of surgical site infection and pseudomeningocele, need for shunt surgery, and recurrence were similar between those undergoing nonsutured and those undergoing sutured dural repair. The mean operative time for the study cohort was 234.9 (SD 106.6) minutes. The nonsutured dural reconstruction group had a significantly shorter mean operative time (223.9 [SD 99.7] minutes) than the sutured dural repair group (254.5 [SD 115.8] minutes) (p = 0.015). In a multivariable linear regression analysis, after controlling for tumor size and sinus involvement, nonsutured dural graft reconstruction was associated with a 36.8-minute reduction (95% CI −60.3 to −13.2 minutes; p = 0.002) in operative time.

CONCLUSIONS

Dural reconstruction using a nonsutured graft and sutured dural repair exhibit similar postoperative outcomes for patients undergoing resection for supratentorial meningiomas. Although sutured grafts may sometimes be necessary, nonsutured graft reconstruction for most supratentorial meningioma resections may suffice. The decreased operative time associated with nonsutured grafts may ultimately result in cost savings. These findings should be taken into consideration when selecting a dural reconstruction technique for supratentorial meningioma.

OBJECTIVE

The aim of this study was to investigate the efficacy and safety of endovascular treatment (EVT) plus standard medical treatment (SMT) in patients with acute basilar artery occlusion (BAO) within 6 hours of the estimated occlusion time, based on a Chinese population.

METHODS

The authors selected patients from the Endovascular Treatment of Acute Basilar Artery Occlusion Study (BASILAR) registry, which was a nationwide prospective registry, within 6 hours after the estimated time of onset of a stroke in acute BAO. Patients were divided into the SMT-alone group or the EVT+SMT group according to treatment modalities. The primary outcome was a favorable functional outcome, defined as a modified Rankin Scale score between 0 and 3 at 90 days. Safety outcomes included death at 90 days and symptomatic intracerebral hemorrhage.

RESULTS

The authors assessed 590 patients for eligibility. Of these patients, 127 received SMT alone and 463 were treated with EVT plus SMT. EVT was associated with a higher rate of a favorable functional outcome (adjusted OR 3.804, 95% CI 1.890–7.658; p < 0.001) and a lower proportion of deaths at 90 days (adjusted OR 0.364, 95% CI 0.223–0.594; p < 0.001). Lower age (adjusted OR 0.978, 95% CI 0.960–0.997; p = 0.022); lower baseline National Institutes of Health Stroke Scale score (adjusted OR 0.926, 95% CI 0.902–0.950; p < 0.001); higher baseline posterior circulation Alberta Stroke Program Early CT Score (adjusted OR 1.681, 95% CI 1.424–1.984; p < 0.001); absence of diabetes mellitus (adjusted OR 0.482, 95% CI 0.267–0.871; p = 0.016); and modified Thrombolysis in Cerebral Infarction scores 2b–3 (adjusted OR 5.117, 95% CI 2.304–11.367; p < 0.001) were independent factors for a favorable outcome in the EVT+SMT group.

CONCLUSIONS

Based on the study design, patients with acute BAO who received EVT within 6 hours were associated with improved favorable outcome and decreased deaths compared with patients who received SMT. Predictors of desirable outcome in patients undergoing EVT included lower age, lower baseline National Institutes of Health Stroke Scale score, higher baseline posterior circulation Alberta Stroke Program Early CT Score, absence of diabetes mellitus, and modified Thrombolysis in Cerebral Infarction scores 2b–3.

Published: June 2022

OBJECTIVE

Embryonal tumor with multilayered rosettes (ETMR) is one of the childhood central nervous system tumors with the poorest prognosis; thus, establishing an optimal treatment strategy is essential, However, because of the low incidence and molecular heterogeneity of the tumor, the optimal treatment has not yet been determined. In this study the authors evaluated the prognostic impact of a multimodal treatment approach in patients with ETMR.

METHODS

The authors evaluated 4 patients with ETMR at their institution who showed varied clinical features and also conducted clinical characterization and prognostic analysis of previously reported cases of the ETMR-presenting locus 19q13.42 with a chromosome 19 microRNA cluster (C19MC) amplification, which is known to be a diagnostic hallmark of the tumor.

RESULTS

Of the 4 patients with ETMR in the authors’ institution, in 1 case the patient’s tumor showed a neuroblastoma-like appearance without multilayered rosettes; however, the diagnosis was confirmed by the presence of amplified C19MC. From a clinical standpoint, 2 patients who underwent gross-total resection (GTR) of the tumor and chemotherapy followed by high-dose chemotherapy (HDC) had long-term complete remission with or without local irradiation. In the multivariate analysis of 43 cases with C19MC-altered ETMR reported in the literature, HDC and local irradiation were significantly correlated with better event-free survival (HR 0.17, p = 0.0087; HR 0.17, p = 0.010) and overall survival (OS) (HR 0.29, p = 0.023; HR 0.28, p = 0.019), respectively. GTR was also correlated with better OS (HR 0.40, p = 0.039).

CONCLUSIONS

This case series demonstrated pathological and clinical heterogeneity among ETMR cases and the diagnostic importance of the molecular genetic approach among embryonal tumors, particularly during infancy. Based on the results of the analysis of molecularly uniformed ETMR cases, multimodal treatment may play a significant role in the prognosis of these tumors.

The name Setia Hati Terate Brotherhood means prioritizing relationships between others that grow from a sincere, sincere, and clean heart. In addition, it was also explained that all members of the Setia Hati Terate Brotherhood are one brother who does not distinguish between rank, degree, and dignity as well as ethnicity, religion, race, and inter-group (SARA). One of the constraining factors for the development of Pencak silat which is in the spotlight is the lack of trainers who are qualified in selecting athletes. Considering all the reasons for the problems at the research site, it is necessary to create a decision support system that can be used by coaches and organizers of an open selection that can assist in selecting athletes to get the most potential athletes to achieve maximum performance. The selection system for Pencak silat athletes will use the AHP method which can decompose problems into a hierarchy so that it is easy to solve, while TOPSIS is a ranking method that has the advantage that it considers the best solution not only the solution closest to the ideal solution but also the most far from a negative solution. The method used is the Analytical Hierarchy Process (AHP) and Technique For Order Preference By Similarity To Ideal Solution (TOPSIS) with the PHP programming language. This study has applied the analytical hierarchy process (AHP) method to determine and test the consistency of the weight of the criteria which includes 4 criteria, namely physical, technical, psychological, and strategic. This research uses the application of the AHP and (TOPSIS) methods with the test results, it is concluded that the system built is more effective in selecting Pencak silat athletes than the test team without using the system.

Ambivalente Verstrickungen – elterliche Positionierungen im Schulkontext zwischen ökonomisierten Rationalitäten, Elternschaftsnormen und Machtverhältnissen
Authors: Ivanova-Chessex Oxana
Published: June 2022

Anhand von Ausschnitten aus einer biographischen Fallrekonstruktion beleuchtet dieser Beitrag brüchige Aushandlungen von Eltern mit der Schule im Kontext institutionell vermittelter ökonomisierter Rationalitäten, Elternschaftsnormen und Machtverhältnisse. Gefragt wird, wie Eltern in die normierten und ökonomisierten Verhältnisse in Bildungskontexten verstrickt werden und wie sie sich zu den an sie normativ herangetragenen Erwartungen und Anrufungen verhalten. Die Analyse verdeutlicht machtvolle Effekte der schulisch wirksamen Normen und Leistungserwartungen des ökonomisierten Bildungswesens und zeigt auf, wie diese normativen Kontexte und Machtverhältnisse elterliche Subjektivitäten und Handlungsspielräume bei der Zusammenarbeit mit Schule ordnen.
Zwischen Dekonstruktion und Reproduktion diskriminierender Schulkulturen: Kooperationen von Schulen und zivilgesellschaftlichen Bildungsinitiativen im Kontext von Flucht
Authors: Kollender Ellen
Published: June 2022

Im Kontext verstärkter Fluchtmigration(en) nach Deutschland, insbesondere im Zuge des Syrienkrieges, sind zahlreiche Initiativen für, von und mit ‚Geflüchtete(n)‘ entstanden, von denen aktuell viele mit Schulen kooperieren. Basierend auf qualitativen Interviews beschäftigt sich dieser Beitrag mit den Perspektiven zivilgesellschaftlicher Initiativen auf schulische Diskriminierung von Schüler_innen mit (zugeschriebener) Flucht-/Migrationsgeschichte sowie hierauf bezogene Schulentwicklungsprozesse. Identifiziert und analysiert werden verschiedene Spannungsfelder, in denen sich die Kooperation zwischen außerschulischen Bildungsinitiativen und Schulen bewegt, die sowohl behördliche Förderlogiken, machtvolle migrationsgesellschaftliche Diskurse als auch schulische Routinen im Umgang mit Diversität und Differenz tangieren. Über die Analyse werden Potentiale und Herausforderungen hinsichtlich der Bearbeitung von (rassistischer) Diskriminierung im Rahmen der Kooperationen deutlich ebenso wie die Bedeutung eines Verständnisses von diskriminierungssensibler Professionalität als Fähigkeit, mit widersprüchlichen Anforderungen umzugehen.
Edutainment – als Muster für Binnendifferenzierung? Rekonstruktion einer Doppelstunde inklusiven Geschichtsunterrichts
Authors: Koßmann Raphael
Published: June 2022

Wie fachliche Vermittlungsprozesse in inklusiven Klassen im Schulalltag umgesetzt werden, wurde trotz der Relevanz dieser Frage für Theorie und Praxis bislang selten untersucht. Anhand einer Doppelstunde Geschichtsunterrichts in einer stark heterogenen, achten Klasse einer integrierten Gesamtschule konnte sequenzanalytisch ein didaktisches Muster rekonstruiert werden, das als inklusiv zu bezeichnen ist und zugleich fachlichen Ansprüchen genügt. Obwohl keine digitalen Medien zum Einsatz gekommen sind, mutet das vorgefundene didaktische Handeln wie eine interaktive Geschichtsdokumentation an. Es drängen sich tieferliegende Gemeinsamkeiten von Didaktik und Programmierung auf, die die Wahrnehmung von digitalisierungsbezogenen Innovationen schulischen Unterrichts schärfen dürften.
The Repurposed UN Trusteeship Council for the Future+
Authors: Desai Bharat H.
Published: June 2022

The idea of the revival and repurpose for the United Nations Trusteeship Council (UNTC) is pragmatic one to meet the needs of the changed times. Such repurpose entails entrustment of a new mandate to the revived UNTC that constitutes evolution of the trust in the global domain. It will be crucial restructuring and evolution of the UN with an understanding that there are places, territories, and areas known as ‘global commons’ that require special and careful nurturing for our better future. In a new avatar (form), the TC would in essence reflect the ‘sacred trust’ with a ‘new mandate.’ From a scholarly perspective, such a move eminently makes sense since it could bring to life an entity within the UN and provide a big push to make the UN relevant for the needs of the present and future generations. It will essentially serve as a guardian of the global ‘common concerns’, ‘common heritage of mankind’ and the global environment. In the changed context, the UNTC need to serve as a trustee for betterment of the humankind and for the survival of the planet earth. The new mandate for the environment and the global commons could strengthen the UN and vindicate one of the core purposes for which the ‘United Nations’ came together in 1945 with a solemn resolve “to establish conditions under which justice and respect for the obligations arising from treaties and other sources of international law can be maintained”.
Convergence in International Environmental and Natural Resources Law
Authors: McIntyre Owen
Published: June 2022

Despite the extraordinary proliferation of instruments of international environmental law since the 1972 UNCHE Conference in Stockholm, it appears that diverse forces are acting to maintain the internal coherence of this sub-field of international law, as well as its position firmly within the international law system. A range of institutions and processes ensure the continuing unitary nature of international environmental law within a unitary system of international law, notably including the universalist instincts of the International Court of Justice, the codification routinely undertaken by the International Law Commission, and the universal, pervasive and indivisible character of increasingly relevant human rights norms. These processes of “convergence” act to unify and enrich the fabric of the increasingly elaborate and sophisticated complex of rules, principles and institutional structures comprising international environmental law, while suggesting its growing developmental maturity after 50 years of frenetic evolution and supporting its continuing coherent elaboration.
Linguistic q-rung orthopair fuzzy multiple-attribute group decision making based on the grey similarity degree and PROMETHEE II method

Published: June 2022

Linguistic q-rung orthopair fuzzy numbers (Lq-ROFNs) are an effective tool for representing fuzzy linguistic information, and they can obtain a wider expression scope than linguistic intuitionistic fuzzy numbers and linguistic Pythagorean fuzzy numbers by increasing the value of parameter q. In this paper, we propose a new similarity measure called the grey similarity degree between any two Lq-ROFNs based on the concept of the grey correlation degree. Considering the significance of determining unknown weights, we also propose a grey correlation method to determine each expert’s weight under different alternatives and attributes, and we construct an optimization model to determine incompletely known attribute weights. Furthermore, an approach to linguistic q-rung orthopair fuzzy multiple-attribute group decision making is proposed that combines the grey similarity degree with the PROMETHEE II method. Finally, a numerical example is given to illustrate the effectiveness of the proposed method, and a sensitivity analysis and comparison analysis are also performed.
Algorithms for multiple attribute group decision making with intuitionistic 2-tuple linguistic information and its application
Authors: Jiang Xian-Ping
Published: June 2022

Recently, the TODIM has been used to deal with multiple attribute decision making (MADM) problems. The intuitionistic 2-tuple linguistic sets (I2TLSs) are useful tools to depict uncertainty in MADM. This paper use TODIM method to solve MADM with the intuitionistic 2-tuple linguistic numbers (I2TLNs). Firstly, the concepts of I2TLNs are briefly presented, and classical TODIM for MADM are introduced. Then, the classical TODIM method is used to solve MADM with I2TLNs, and its important characteristic is to fully consider the decision makers’ bounded rationality which is a real action in MADM. And a comparative analysis is also given. Finally, a numerical example for service outsourcing providers selection is proposed.

A dataset that has massive features and imbalanced classes may be challenging for obtaining adequate accuracy in classification approaches of Machine Learning (ML). The purpose of this research is to find the optimal feature subset for cervical cancer diagnosis with efficient classification approach by estimating the performance of various Machine Learning predictive models. Filter-based feature selection techniques of Relief and Information Gain are applied in this study to calculate the rank for each feature that can be applied to order and select highest scoring features for feature selection. An optimal feature subset is generated with wrapper approach through Recursive Feature Elimination which uses a Random Forest procedure and Genetic Algorithm has been employed based on evolutionary principle. The predictive models are established with 10fold cross validation using prevalent classification algorithms like Random Forest, C5.0, K-Nearest Neighbour and Naïve Bayes. The results showed an enhancement in the average performance of these classifiers concurrently and the classification error for these classifiers decreases substantially. The experiments also exhibited that by employing this approach an optimal and reduced feature subset is desirable for the enrichment of classification accuracy with a lower computational cost. The features generated by fused approach of Relief and Genetic algorithm methods were able to predict the results in an efficient manner, hence an optimal feature subset has been nominated through this procedure. Maximum number of classifiers have shown good results in terms of performance outcomes. In addition, Random Forest method has shown advanced accuracy rate with an improved percentage of sensitivity and specificity results. Also, this work established that the best and optimal feature subset selection through Fused Feature Selection (FFS) approach could reduce the complexity of the predictive model.
