Prebiotic Aggregates (Tissues) Emerging from Reaction–Diffusion: Formation Time, Configuration Entropy and Optimal Spatial Dimension

For the formation of a proto-tissue, rather than a protocell, the use of reactant dynamics in a finite spatial region is considered. The framework is established on the basic concepts of replication, diversity, and heredity. Heredity, in the sense of the continuity of information and alike traits, is characterized by the number of equivalent patterns conferring viability against selection processes. In the case of structural parameters and the diffusion coefficient of ribonucleic acid, the formation time ranges between a few years to some decades, depending on the spatial dimension (fractional or not). As long as equivalent patterns exist, the configuration entropy of proto-tissues can be defined and used as a practical tool. Consequently, the maximal diversity and weak fluctuations, for which proto-tissues can develop, occur at the spatial dimension 2.5.

KnowMIS-ABSA: an overview and a reference model for applications of sentiment analysis and aspect-based sentiment analysis

The analysis of the opinions of customers and users has been always of great interest in supporting decision-making in many fields, especially in marketing. Sentiment analysis (SA) is the umbrella term for techniques and approaches that analyze user’s sentiments, emotions, opinions in text or other media. The need for a better understanding of these opinions paved the way to novel approaches that focus on the analysis of the sentiment related to specific features of a product, giving birth to the field of aspect-based sentiment analysis (ABSA). Although the increasing interest in this discipline, there is still confusion regarding the basic concepts of ABSA: terms like sentiment, affect, emotion, opinion, are used as synonyms while they represent different concepts. This often leads to an incorrect analysis of the users’ opinions.This work presents an overview of the state-of-the-art techniques and approaches for ABSA, highlighting the main critical issues related to current trends in this field. Following this analysis, a new reference model for SA and ABSA, namely the KnowMIS-ABSA model, is proposed. The model is grounded on the consideration that sentiment, affect, emotion and opinion are very different concepts and that it is profoundly wrong to use the same metric and the same technique to measure them. Accordingly, we argue that different tools and metrics should be adopted to measure each of the dimensions of an opinion. A qualitative case study, regarding product reviews, is proposed to motivate the advantages of the KnowMIS-ABSA model.

Preschool education

Mengaktualisasikan Astha Brata Dalam Konteks Krisis Kepemimpinan

<p><em>Astha Brata is a leading power in the form of eight basic traits that must be ingrained for a leader and potential leader. Astha Brata personifies the power of the elements of the universe, such as sun, moon, stars, sky or sky, wind, ocean (water), earth, and fire. The symbolization of the value of leadership from the universe is converging on the process of self-awareness of a leader or potential leader to be able to appreciate nature in its entirety. The concepts and character of leadership based on local wisdom are still very relevant when applied by leaders or potential leaders at all levels. In fact, amid the rush of imported leadership theories, which are also not one hundred percent in harmony with the life of our nation and state, efforts to explore and re-actualize the concepts and noble values of Astha Brata's leadership are accurate concepts and foundations as well as the main saka guru that must be applied by a leader and potential leader. The concept of Astha Brata must always be applied, especially in dealing with situations and conditions that are "unfriendly" and easily changeable. By understanding the basic concepts of Astha Brata correctly, one will be able to easily tell the difference between a leader and a ruler.</em></p>
