To address the problem of inaccurate matching between personalized exercise recommendations and learners’ mastery of knowledge concepts/learning abilities, we propose the Dynamic Multidimensional Memory Augmented knowledge tracing model (DMMA). This model integrates a dynamic key-value memory neural network with the Ebbinghaus Forgetting Curve. By incorporating time decay factors and knowledge concept mastery speed factors, it dynamically adjusts knowledge update intensity, effectively resolving the insufficient personalized recommendation capabilities of traditional models. Experimental validation demonstrates its effectiveness: on Algebra 2006–2007, DMMA achieves 82% accuracy, outperforming CRDP-KT by 6%, while maintaining 53–55% accuracy for cold-start users (0–5 interactions), which is 25% higher than CoKT. The model’s integration of the Ebbinghaus forgetting curve and K-means-based concept classification enhances adaptability. Genetic algorithm optimization yields a diversity score of 0.79, with 18% higher 30-day knowledge retention. The FastDTW–Sigmoid hybrid similarity calculation (weight transition 0.27–0.88) ensures smooth cold-start adaptation, while novelty metrics reach 0.65 via random-forest-driven prediction. Ablation studies confirm component necessity: removing time decay factors reduces accuracy by 2.2%. These results validate DMMA’s superior performance in personalized education.

Learning factual information is an activity that most individuals have engaged in during their schooling, at university, or in specific courses. It is commonly stated that one \"absorbs\" facts, with the intention of retaining the learned material over time. According to memory psychologist Hermann Ebbinghaus, a specific pattern must be followed to prevent the forgetting of learned material. Ebbinghaus, H. (1885) Uber das Gedächtnis zur Experimentellen Psychologie Verlag von Duncker & Humblot, Leipzig. The article outlines the approach necessary to maximize retention. When a considerable number of individuals adhere to Ebbinghaus's pattern, it results in a group whose memory of the learned material improves from a lower level to a significantly higher one. If this group comprises employees within an organization, it leads to what is known as a \"knowledge gain\" for the organization, thereby enhancing the overall quality of its collective knowledge. This pertains to the concept of organizational memory-the total knowledge residing within an organization. In the article by Walsh J.P. and Ungson G.R. (1991), titled \"Organizational Memory,\" published in the Academy of Management Review, the authors highlight the critical importance of effectively managing and leveraging an organization's accumulated knowledge, thereby elevating the practice of knowledge management.

In the mid-fourteenth century the Black Death inflicted one of the most devastating losses of life in human history. This was met by exercises of collective piety such as the singing of psalms and the celebration of special votive masses, which encouraged social cohesion in the face of the tragedy. This article presents results from an analysis of fifty-seven manuscripts containing copies of the monophonic ‘Recordare domine’ Mass, reportedly created at the behest of Clement VI at Avignon during his Black Death-spanning pontificate. Of these, seven manuscripts contain fully notated renditions of each of the chants for the Mass Propers, enabling us to decouple questions concerning the organisation and transmission of the melodies from those of the texts set to them. When the different versions of the Mass are compared, two major findings emerge. First, differential patterns of consistency within the texts and melodies suggest that the texts of the ‘Recordare domine’ Mass may have circulated separately from the melodies set to them, with the choice of music left to the discretion of the local performing clergy. Second, the patterns of variation between different versions of the Proper texts and melodies allow us to see how a variety of composition strategies (including mnemonic processes) were used to create new music for the mass. The ‘Recordare domine’ Mass thus sheds light not only on the performance of organised sacred music at a pivotal point in European history, but also more generally on the processes of chant composition as a tool for use in response to social stress.

This article examines the internationalization of scientific and scholarly communication in the period before World War I, taking philosophy as an example. In the first part of the article, several general trends in internationalization during the nineteenth and twentieth centuries are examined. This includes the importance of international experience for Russia's policies today towards science and education. The main part of this article is devoted to the concept of the \"international argument\" and provides an analysis of three types of appeal to the international community: the pragmatic, the reputational, and the communicative. The increasing importance of international communication during this period is shown on the basis of examples drawn from German philosophical discussions that took place between the first third and the end of the nineteenth century (the case of Friedrich Eduard Beneke and Hermann Ebbinghaus). The last part of the article examines the impact on German science and philosophy of the cessation of international communication during World War I.

According to The Teambuilding Company,1 these events can produce: * Increased self-esteem, efficacy and understanding within the individuals who form the team. * Increased willingness to share ideas with teammates. * Reduced stress levels. * More unity towards common goals and aspirations. * Increases in overall group functioning. [...]in the short term, these workers' productivity, profitability and return on investment is reduced.
