Evaluating the network traffic on an improved version of the Committeeless Proof-of-Stake blockchain consensus algorithm
Authors: Gigilas Junior George , Ferreira Filipe Franco , Henriques Marco A. A.
Published: September 2024

Blockchain is a powerful way to store and process data in a decentralized way. Among its consensus algorithms, Committeeless Proof-of-Stake (CPoS) is a promising alternative to the better-known Proof-of-Work and Proof-of-Stake, with its reduced power consumption and more straightforward design without validation committees. However, CPoS is still an emerging algorithm and requires more testing to validate its correctness and efficiency. One of the problems it has to deal with is the higher network traffic compared to similar approaches due to the larger number of messages sent. This article aims to modify CPoS in order to reduce the data traffic and improve its performance.

Authors: Silva Brendon Vicente R. , Schardong Frederico , Custódio Ricardo F.
Published: September 2024

This paper introduces and addresses challenges in managing electronic identity’s Level of Assurance (LoA), which has two types: LoA of authentication and LoA of identity. We explore different technical specifications, protocols, and concrete identity providers’ strategies for managing these two levels of assurance, highlighting the implications of protocols supporting only a single LoA instead of two. An extension to the OpenID Connect protocol is proposed to support both LoA types, instituting a new claim, the Identity Context Class Reference (ICR). This approach ensures compatibility and versatility with existing technical specifications.

Olympische Spiele Paris 1924: „Wunderläufer“ machen das kleine Finnland zu einer sportlichen Großmacht
Authors: Kluge Volker
Published: September 2024

With the exception of Brazil’s football star Pelé, probably no nation has been more identified with an athlete than little Finland, which produced the “Flying Finn” Paavo Nurmi. 100 years ago, he won five gold medals at the 1924 Olympic Games in Paris. Subsequently, monuments were erected in his honour, and the German sculptress Renée Sintenis dedicated a statuette to him. His picture adorns Finnish banknotes, coins, and stamps. A Berlin primary school and an asteroid bear his name, and streets were named after him. A gelding called “Nurmi” was the Olympic champion in the Three-Day Event (Military). What was the secret of this taciturn athlete, who gave virtually no interviews, but who was able to enthral the North American continent with his performances? What characterised Finnish sport, which, with its extraordinary Olympic successes, was also utilised by politicians for foreign policy and economic interests?
Heideggers »Schwarze Hefte«
Authors: Marafioti Rosa Maria
Published: September 2024

Composed between 1931 and 1970, the “Black Notebooks” mark the longest stretch of Heidegger’s path of thought. This book is the first comprehensive analysis of Heidegger’s Notes, which were published in the span of nine years, situating them within the context of the life and work of its author as well as in the time in which they were conceived. The “Notebooks” confirm Heidegger’s capability to recognise his own steps as “beaten track” that can lead to dead ends. They give the contemporary man the task of recognising his own finitude and of taking responsibility for all areas of meaning in the world. Rosa Marafioti is a professor at the University of Bergamo; her field of research includes phenomenology, hermeneutics and German idealism.

Authors: Ruhs Yves
Published: September 2024

The bail-in instrument aims to protect Europe and the United States against the expansion of the next banking crisis into a financial market or sovereign debt crisis. However, the Single Point of Entry strategy developed by the FDIC and the European open-bank bail-in strategy are two diametrically opposed resolution strategies, neither of which has yet been tested in a real-world crisis. In this study, the author investigates to what extent government authorities and politicians can influence or delay a resolution decision. Furthermore, a legal and procedural comparison between the US and European resolution frameworks is used to identify necessary short- and long-term measures to improve the viability of both bail-in instruments.

Authors: Nizamiyati Nizamiyati , Brilliant Muhamad
Published: September 2024

Road damage in Lampung Province poses a serious threat to public safety and transportation, necessitating immediate government assistance. Despite the necessity for fast repair, there has been a lack of an appropriate platform for public reporting, making road inspections inefficient and error prone. This study makes two significant contributions: (1) the creation of a comprehensive dataset documenting road damage in Lampung, using samples collected in Pesawaran Regency, and (2) the development of an automated road damage identification and reporting system based on the YOLOv7 object detection model. The technology detects damage types such as alligator cracking, corrugation, depression, and potholes and provides real-time geolocation to improve reporting accuracy. Furthermore, it allows the public to report road damage. The model was trained on 1,200 pictures over 100 epochs, yielding a mean average precision (mAP) of 0.6. System performance was evaluated using precision and recall metrics, and compatibility testing confirmed that the system works reliably across various devices and browsers. This research enhances road maintenance by making inspections faster and more precise, while also promoting greater public involvement. Future work could integrate additional data sources, such as satellite imagery or IoT technology. to further increase the system’s scalability and accuracy.
Opportunities and ways of teaching stochastics elements in school mathematics training
Authors: Ibrahimova Naila
Published: September 2024

The strategies and approaches utilized in school textbooks and methodical literature to teach the elements of probability theory make it evident that, in order for students to fully understand the theory of probability, they must be able to identify the statistical indicators of events that occur in the course of their daily lives. In accordance with said idea, it would be good to start with the questions posed that require the solution of the activities of students' daily life and related to the corresponding situation. As a result, not every theorem presented as theoretical information in mathematics training needs to be proven. Quite a lot of time is spent on proving those theorems, but also the tasks of the course include the formation of useful habits, and not the skills of proving theorems. The process of introducing the content line “Statistics and Probability” into the school mathematics course is a typical and rather complicated task. There is such a thesis that in order to master the beginnings of probability theory, students should be instilled with knowledge and skills with new training methods, unlike traditional training. Considering this, teaching the younger generation essential skills is the only thing that bothers psychologists and educators in the modern day. Because the student must deeply feel the ideas about the vital problems surrounding him, self-identify them, evaluate them as an independent line in the direction of formation of logical thinking, development of activity of thinking. Due to the new inclusion of probability theory and statistics in school mathematics, the problem of implementing these materials in school textbooks has arisen. Also, the number of methodical literature related to the specific features of this course is not so large yet. Therefore, the creation of a technique for teaching probability theory and statistics in general education classrooms, as well as an analysis of the course's outcomes, constitute real topics.

Published: September 2024

This informative study aims to clarify the quality assurance in higher education at the university level in the Division of Bahawalpur. The objectives of this study are: to find out the difference in quality assurance among students of different universities (public and private), to compare learning and teaching strategies, to identify reasons for quality assurance failure, to analyze physical infrastructure and academic facilities, and to compare the administrative facilities between these institutions. A descriptive quantitative survey design was selected for this study. The population of this study is all universities (Government and Private) located in the Division Bahawalpur and 07 universities were chosen as a sample. Of these 07 universities, 514 students (boys and girls) and 48 teachers (males and females) participated in this study as a sample. The simple random sampling technique is used. For data collection, two self-structured questionnaires were employed; one for students and one for teachers, each consisting of 40 items. After data collection, it was analyzed with the help of SPSS. The findings revealed that public universities have difficulty keeping up-to-date infrastructure and attempting to adapt contemporary teaching tactics, whereas private institutions often have superior administrative resources and more sophisticated teaching methodologies. It is suggested that to guarantee uniformity in educational quality, all universities should use a common quality assurance system and provide a favorable learning environment, increase spending on academic facilities, and encourage cooperation between public and private institutions to exchange best practices in quality and learning for progress.

IS INDIA HEADING TOWARDS TRADE PROTECTIONISM: AN ANALYSIS OF CAROTAR RULES?
Authors: Singh Surendar , Singh Ram
Published: September 2024

With the announcement of Self-Reliant India Mission, the Government of India has announced several policy measures to promote domestic manufacturing to make India, as a hub of global manufacturing. One of its major policy measures is the introduction of Customs (Administration of Rules of Origin under Trade Agreements) Rules, 2020 (CAROTAR Rules). The objective of these rules is to regulate frivolous imports of the third country, which is routing to the Indian market via its FTA partners. These rules have created ‘lots of hues and cry’ among importing and exporting firms due to their regulatory, operational and business implications. This article examines key provisions of CAROTAR rules and their implications to India’s foreign trade sector in general and exporting and importing firms in particular. Findings show that CAROTAR rules are highly protective and regressive in nature and designed to safeguard the domestic manufacturing industry. The intent and content of these rules clearly demonstrate that importing firms are subject to strict regulatory compliance to claim preferential benefit under India’s existing trade agreements. New rules will increase the cost of importing inputs and components thereby affecting India’s trade competitiveness.

INDIA’S BITTER SUGAR POLICY: PRODUCTION, EXPORT, SUBSIDY, AND OTHER DISTORTIONS
Authors: Rastogi Siddhartha K. , Sengupta Anirban
Published: September 2024

While sugar is widely and progressively highly consumed worldwide, sugar production and exports are highly concentrated among a few countries. This invites many market distortions and demand-supply gaps. India, being the largest producer and the third-largest exporter, creates a lot more distortions than other major producers. Two main sources of volatility are India’s production subsidies and export subsidies. These subsidies violate WTO principles of fair trade and increase volatility for other countries too. In addition, sugar is a disaster crop for India as it gets a high premium of subsidies and therefore crowds out other crops, causes resource diversion and immense groundwater depletion, and harbingers a public health crisis in the form of obesity and life-style diseases. We explore the dynamics of the world sugar market, the sources of all the above distortions and adverse effects of the sugar industry, and explore remedial courses, while keeping in mind the political realities.Keywords: Sugar, Subsidies, Exports, Trade Distortion, Agricultural Policy.

Authors: Kumar K Kiran
Published: September 2024

High volatility in the stock market is often attributed to derivative expirations. The National Stock Exchange of India, largest derivatives exchange in the world by number of contracts traded, introduced weekly or short-dated derivatives in Feb 2019 to mitigate the expiration day effects. The study empirically examines the return and volatility data surrounding expiration days during the period before and after the introduction of weekly derivatives. First, for the period before the introduction of weekly contracts, the study gathers empirical evidence suggesting the presence of upward shift in price effects around expiration day and a transitory upward shift in volatility. Next, the study shows with a comprehensive time series analysis, these adverse expiration day effects disappear in the period after the introduction of weekly options. The paper concludes that the weekly, short-dated, contracts fill the gap in the market depth and are beneficial to the over all market welfare. As the weekly options are gaining popularity across the exchanges and investors, the study has important implications to the regulators and practitioners around the world.

Excited attention towards the disclosure of methods – what is termed ‘exposure’– infuses both popular and practitioners’ portrayals of entertainment magic.  As an art associated with ‘doing the impossible’, the disclosure of methods is widely held as ruining the prospects for experiencing astonishment.  For all its familiarity, however, exposure is rarely subject to extended consideration in the thoughts and theories of professional magicians.  In line with a tradition of conceiving of magic as a form of social interaction constituted through the relations between audiences and performers, this article offers a theorization of exposure; one grounded in empirical research with magicians.  Varied notions of ‘boundary work’ are engaged which provide means for doing justice to the nuances of what it means to expose the secrets of magic.  As an intervention into ongoing debates about what counts as appropriate conduct, the ultimate aim of the article is to help re-imagine what is at stake in conjuring.

Introducción: La seguridad de los pacientes en el quirófano es un desafío constante para los enfermeros quirúrgicos debido a la naturaleza de alto riesgo de las intervenciones quirúrgicas. La comunicación deficiente entre los equipos médicos y la capacitación insuficiente pueden aumentar la probabilidad de eventos adversos. Metodología: Para la recolección de información se utilizaron bases de datos como Scielo, Biblioteca Virtual en Salud, OMS, Google Académico y PubMed. Se aplicó el método PRISMA para la clasificación y selección de estudios, revisando un total de 45 artículos, de los cuales 25 se consideraron relevantes para el análisis. Resultados: Los hallazgos indican que los eventos adversos en entornos quirúrgicos afectan entre el 3% y el 16% de los pacientes. Aunque la implementación de la Lista de Verificación de Cirugía Segura ha demostrado ser efectiva en la reducción de estos eventos, su aplicación enfrenta varios desafíos, como la falta de formación y la resistencia cultural en algunos entornos quirúrgicos. Conclusión: Es evidente que, si bien existen herramientas y protocolos para mejorar la seguridad quirúrgica, su efectividad depende en gran medida de la capacitación continua y el compromiso de todo el equipo médico. La revisión sugiere que muchos de los eventos adversos son prevenibles. Destaca la necesidad de reforzar la formación y sensibilización sobre la importancia de las prácticas seguras, garantizando la participación activa de todos los profesionales de salud en la seguridad quirúrgica.

It effectively minimizes the number of vehicles, with transportation costs resulting just 0,38% above the best solution found on Solomon test instances. The approach limits search time to about 10 minutes, effectively balancing complexity and solution quality.
Review of the adaptive Swedish traffic conflict technique: Applications and implications for road traffic safety
Authors: Pratama Wahyu , Mahmudah Noor
Published: September 2024

The Swedish Traffic Conflicts Technique (STCT) is a systematic approach used to examine traffic conflicts, specifically emphasising the correlation between severe conflicts and accidents. It uses safety indicators such as average speed, post-encroachment time, deceleration rate, time to collision, and traffic flow size to evaluate the gravity of interactions between pedestrian and motorised vehicles. The development of the TCT has been significant, with studies highlighting the impact of speeding, inattentiveness, inadequate following distance, signal violations, drowsiness, excessive alcohol consumption, and reckless driving on road safety. The Adaptive STCT for road traffic safety is a significant area of research and development, aiming to enhance understanding of the global implementation and efficacy of the Adaptive Swedish TCT in enhancing road traffic safety. The STCT has been applied in various countries, including Sao Carlos, Nanjing, Ho Chi Minh City, and Qatar, and has shown significant development in identifying hazardous manoeuvres at urban intersections, facilitating the adoption of safer designs and efficient risk management measures. Nevertheless, research on the STCT's implementation on rural roads is limited; it highlights the need for further investigation and implementation in rural environments due to varying road safety issues.

Guidelines for the implementation of first aid measures are part of the Guidelines 2021 of the European Resuscitation Council from 2015. In 2020, the ILCOR Committee made a scientific consensus for this area, and the European Resuscitation Council in 2021 made new recommendations based on this document and reviewed the existing ones. Recommendations for the application of first aid measures include first aid in emergencies and injuries. Recommendations that include emergencies consider the following content: recovery position, optimal positioning for shock, use of bronchodilators in patients with asthma in first aid, recognition of stroke, use of aspirin for chest pain, giving a second dose of adrenaline in anaphylaxis, first aid for hypoglycemia , oral rehydration, first aid for stress - related dehydration, heat stroke management and application of cooling measures, use of oxygen in providing first aid measures in acute stroke, and first aid for presyncope. First aid for trauma includes the following topics: control of life-threatening bleeding, first aid and treatment of open chest injuries, recognition of concussions, cooling burns, dental avulsion, and first aid for eye injuries due to exposure to chemicals.

In a turbulent and increasingly demanding labor market, the gap between the demand for skilled workers and the supply of qualified job seekers is evident. The authors aimed to identify crucial competencies for the 21st century that should be actively developed in higher education institutions. The research sample consisted of 137 participants from two private universities in the Republic of Serbia. The study found a strong correlation between certain competencies developed during studies and those developed independently of studies. Additionally, students with developed research skills exhibited greater information management skills. Factor analysis results supported the division of skills into two component groups. The first group, associated with static competencies, refers to an individual's innate cognitive ability to effectively manage and understand various behaviors. The second group, associated with dynamic competencies, depends on external influences to ensure their effective application.

Published: September 2024

In an effort to gather adaptation strategies for reducing or combating rising sea levels (RSLs) faced by Nigerian coastal communities, and encouragement of agricultural activities, a comprehensive review of literature was conducted on similar subject matter based on the previous studies carried out by other researchers across the world. However, impact of and factors promoting rising sea levels were discussed. Their approaches of adaptation were explored on the basis of restricted solutions implemented for efficient management of the RSLs. The study further presents a wide-range of different and well-defined native adaptation strategies and utilized by the affected coastal communities to combat the impact of the RSLs. These strategies included wetland protection and restoration, coastal engineering solutions, among others. This study also underscores the importance of community involvement and collaboration with government in implementing coastal zoning protocols and government policy recommendations to alleviate the negative effect of RSLs.
