Implementation of a Blockchain System Using Improved Elliptic Curve Cryptography Algorithm for the Performance Assessment of the Students in the E-Learning Platform

Blockchain technology allows for the decentralized creation of a propagated record of digital events, in which third parties do not control information and associated transactions. This methodology was initially developed for value transmission. Still, it now has a broad array of utilization in various industries, including health, banking, the internet of things, and several others. With its numerous added benefits, a blockchain-based learning management system is a commonly utilized methodology at academic institutes, and more specifically during and after the COVID-19 period. It also presents several potentials for decentralized, interoperable record management in the academic system in education. Integrity, authenticity, and peer-executed smart contracts (SC) are some of the qualities of a blockchain that could introduce a new degree of safety, trustworthiness, and openness to e-learning. This research proposes a unique encryption technique for implementing a blockchain system in an e-learning (EL) environment to promote transparency in assessment procedures. Our methodology may automate evaluations and provide credentials. We built it to be analytical and content-neutral in order to demonstrate the advantages of a blockchain back-end to end-users, including student and faculty members particularly during this COVID-19 era. This article explains the employment of blockchain and SC in e-learning. To improve the trust in the assessment, we propose a novel improved elliptic curve cryptography algorithm (IECCA) for data encryption and decryption. The performance of the suggested method is examined by comparing it with various existing algorithms of encryption. The evaluation of the behaviour of the presented method demonstrates that the technique shall enhance trust in online educational systems, assessment processes, educational history, and credentials.

6G Cognitive Information Theory: A Mailbox Perspective

With the rapid development of 5G communications, enhanced mobile broadband, massive machine type communications and ultra-reliable low latency communications are widely supported. However, a 5G communication system is still based on Shannon’s information theory, while the meaning and value of information itself are not taken into account in the process of transmission. Therefore, it is difficult to meet the requirements of intelligence, customization, and value transmission of 6G networks. In order to solve the above challenges, we propose a 6G mailbox theory, namely a cognitive information carrier to enable distributed algorithm embedding for intelligence networking. Based on Mailbox, a 6G network will form an intelligent agent with self-organization, self-learning, self-adaptation, and continuous evolution capabilities. With the intelligent agent, redundant transmission of data can be reduced while the value transmission of information can be improved. Then, the features of mailbox principle are introduced, including polarity, traceability, dynamics, convergence, figurability, and dependence. Furthermore, key technologies with which value transmission of information can be realized are introduced, including knowledge graph, distributed learning, and blockchain. Finally, we establish a cognitive communication system assisted by deep learning. The experimental results show that, compared with a traditional communication system, our communication system performs less data transmission quantity and error.

OSCILLATION PROPERTIES FOR NON-CLASSICAL STURM-LIOUVILLE PROBLEMS WITH ADDITIONAL TRANSMISSION CONDITIONS

This work is aimed at studying some comparison and oscillation properties of boundary value problems (BVP’s) of a new type, which differ from classical problems in that they are defined on two disjoint intervals and include additional transfer conditions that describe the interaction between the left and right intervals. This type of problems we call boundary value-transmission problems (BVTP’s). The main difficulty arises when studying the distribution of zeros of eigenfunctions, since it is unclear how to apply the classical methods of Sturm’s theory to problems of this type. We established new criteria for comparison and oscillation properties and new approaches used to obtain these criteria. The obtained results extend and generalizes the Sturm’s classical theorems on comparison and oscillation.

The Two-Pronged Middle Class: The Old Bourgeoisie, New State-Engineered Middle Class, and Democratic Development

We contribute to research on the democratic role of middle classes. Our paper distinguishes between middle classes emerging autonomously during gradual capitalist development and those fabricated rapidly as part of state-led modernization. To make the case for a conceptual distinction between these groups within one national setting, we employ author-assembled historical district data, survey, and archival materials for pre-Revolutionary Russia and its feudal estates. Our analysis reveals that the bourgeois estate of meshchane covaries with post-communist democratic competitiveness and media freedoms, our proxies of regional democratic variations. We propose two causal pathways explaining the puzzling persistence of social structure despite the Bolsheviks’ leveling ideology and post-communist autocratic consolidation: (a) processes at the juncture of familial channels of human capital transmission and the revolutionaries’ modernization drive and (b) entrepreneurial value transmission outside of state policy. Our findings help refine recent work on political regime orientations of public-sector-dependent societies subjected to authoritarian modernization.

The Role of Communities in the Transmission of Political Values: Evidence from Forced Population Transfers

This article evaluates the role of community bonds in the long-term transmission of political values. At the end of World War II, Poland's borders shifted westward, and the population from the historical region of Galicia (now partly in Ukraine) was displaced to the territory that Poland acquired from Germany. In a quasi-random process, some migrants settled in their new villages as a majority group, preserving communal ties, while others ended up in the minority. The study leverages this natural experiment of history by surveying the descendants of these Galician migrants. The research design provides an important empirical test of the theorized effect of communities on long-term value transmission, which separates the influence of family and community as two competing and complementary mechanisms. The study finds that respondents in Galicia-majority settlements are now more likely to embrace values associated with Austrian imperial rule and are more similar to respondents whose families avoided displacement.

Norms and Values in Refugee Resettlement: A Literature Review of Resettlement to the EU

As a result of the refugee reception crisis in 2015 the advocacy for increasing resettlement numbers in the overall refugee protection framework has gained momentum, as has research on resettlement to the EU. While the UNHCR purports resettlement as a durable solution for the international protection of refugees, resettlement programmes to the European Union are seen as a pillar of the external dimension of the EU’s asylum and migration policies and management. This paper presents and discusses the literature regarding the value transmissions taking place within these programmes. It reviews literature on the European resettlement process – ranging from the selection of refugees to be resettled, the information and training they receive prior to travelling to their new country of residence, their reception upon arrival, their placement and dispersal in the receiving state, as well as programs of private and community sponsorship. The literature shows that even if resettlement can be considered an external dimension of European migration policy, this process does not end at the border. Rather, resettlement entails particular forms of reception, placement and dispersal as well as integration practices that refugees are confronted with once they arrive in their resettlement country. These practices should thus be understood in the context of the resettlement regime as a whole. In this paper we map out where and how values (here understood as ideas about how something should be) and norms (expectations or rules that are socially enforced) are transmitted within this regime. ‘Value transmission’ is here understood in a broad sense, taking into account the values that are directly transmitted through information and education programmes, as well as those informing practices and actors’ decisions. Identifying how norms and values figure in the resettlement regime aid us in further understanding decision making processes, policy making, and the on-the-ground work of practitioners that influence refugees’ lives. An important finding in this literature review is that vulnerability is a central notion in international refugee protection, and even more so in resettlement. Ideas and practices regarding vulnerability are, throughout the resettlement regime, in continuous tension with those of security, integration, and of refugees’ own agency. The literature review and our discussion serve as a point of departure for developing further investigations into the external dimension of value transmission, which in turn can add insights into the role of norms and values in the making and un-making of (external) boundaries/borders.

Developmental Pathways of Preadolescents’ Intrinsic and Extrinsic Values: The Role of Basic Psychological Needs Satisfaction

The purpose of the study was to examine longitudinally how intrinsic and extrinsic values develop during preadolescence within a mother–child context by comparing three different developmental pathways—direct value transmission, indirect value transmission, and value origination. Two hundred and thirty–three Korean mother–child dyads of late elementary students ( Mage = 11.4 years; 55% girls) participated in a year–long online questionnaire survey. A longitudinal structural equation modelling analysis revealed two contrasting developmental pathways for intrinsic and extrinsic values in preadolescents. Intrinsic values developed via value origination, while extrinsic values developed via direct transmission. In other words, intrinsic values originated from the child's own inner psychological experiences and developed in accordance with changes in psychological needs satisfaction, whereas extrinsic values were transmitted from mothers in accordance with the degree to which they endorsed extrinsic values. © 2020 European Association of Personality Psychology
