The Conflict between Top-down and Bottom-up Impairments in Consciousness Disorder in Schizophrenia

Introduction: Schizophrenia, a complex psychiatric disorder, is often associated with consciousness disorders, typically characterized by an elevated threshold of conscious perception. Over the years, a multitude of research has been dedicated to uncovering the primary cause of these disorders, leading to the development of several theories. Methods: In this article, two central answers to this problem have been reviewed. For this, the articles that were more related to the topic were selected. Based on the relevance to the subject of research, the main ideas of targeted articles are reordered to be comprehensible for the readers. Finally, the judgment and conclusion of the authors about the discussed problem are presented in this study. Discussion: The first theory, which we will explore in this article, suggests that the root cause of these disorders lies in defects within bottom-up processes. These processes, fundamental to our understanding of the world, involve the progression of sensory information from low-level perception to high-level awareness. In individuals with schizophrenia, these processes are believed to be compromised, leading to a distorted perception of reality. The second theory, in contrast, attributes the cause to impairments in top-down processes. These processes, which refer to the influence of high-level cognitive functions on lower-level sensory perception, are also considered dysfunctional in schizophrenic patients. This dysfunction is thought to disrupt the integration of sensory information, thereby affecting the individual's consciousness. However, a third perspective has emerged, suggesting the coexistence of impairments in both bottom- up and top-down processing. This perspective argues that to fully comprehend the nature of consciousness disorders in schizophrenia, it is crucial to determine the type and severity of both bottom-up and top-down impairments. Conclusion: In this review, we delve into these theories, examining the evidence supporting each and discussing their implications for our understanding of schizophrenia. Considering both bottom-up and top-down impairments, the third perspective offers a more holistic explanation for these disorders. We further argue that this perspective underscores the need for a more nuanced approach to studying schizophrenia. It suggests that future research should not only focus on these processes in isolation but also explore their interaction and the potential synergistic effects of their impairment. By doing so, we can hope to gain a more comprehensive understanding of consciousness disorders in schizophrenia, which could ultimately lead to more effective treatment strategies.

Convolutional Channel-Wise Competitive Learning for the Forward-Forward Algorithm

The Forward-Forward (FF) Algorithm has been recently proposed to alleviate the issues of backpropagation (BP) commonly used to train deep neural networks. However, its current formulation exhibits limitations such as the generation of negative data, slower convergence, and inadequate performance on complex tasks. In this paper we take the main ideas of FF and improve them by leveraging channel-wise competitive learning in the context of convolutional neural networks for image classification tasks. A layer-wise loss function is introduced that promotes competitive learning and eliminates the need for negative data construction. To enhance both the learning of compositional features and feature space partitioning, a channel-wise feature separator and extractor block is proposed that complements the competitive learning process. Our method outperforms recent FF-based models on image classification tasks, achieving testing errors of 0.58%, 7.69%, 21.89%, and 48.77% on MNIST, Fashion-MNIST, CIFAR-10 and CIFAR-100 respectively. Our approach bridges the performance gap between FF learning and BP methods, indicating the potential of our proposed approach to learn useful representations in a layer-wise modular fashion, enabling more efficient and flexible learning.

Формирование дизайна интерьера квартиры в стиле чиллаут

The article presents the main ideas and solutions for the formation of the interior design of an apartment in the chillout style, which creates a relaxing and soothing environment for residents, while simultaneously organizing a comfortable living environment. The choice of certain color solutions inside the room is justified from the point of view of psychology. The use of non-standard and unexpected options allows people to perceive an object through the prism of their feelings, inspired by the ideas embodied in life. The use of various types of lighting in the interior of a residential space significantly improves the artistic expressiveness of the designed space.

Text structure instruction in primary education: Effects on reading, summarization, and writing

Although knowledge of informational text structures can promote text comprehension, this topic receives little attention in the Dutch primary school curriculum. 201 Dutch students in grades 4-6 participated with their teachers (n = 10) in this quasi-experimental study with a switching-panels replication design. Students either first followed a text structure intervention (TOP) and then went back to business-as-usual, or the other way around. During the intervention, teachers taught their students about the characteristics of four informational text structures, and how to use structure-specific graphic organizers to organize main ideas for each structure. In addition, several writing tasks related to the different text structures were included. At three measurement occasions, students completed text structure tests, reading comprehension tests, summarization tasks, and writing tasks. Only the fourth graders in one iteration of the intervention showed immediate effects over and above the effect of business-as-usual lessons on the text structure test (d = 0.50), the reading comprehension test (d = 0.53), the summarization task (d = 0.48). In both iterations of the intervention, an immediate effect was found on writing (d = 0.33 and d = 0.39). These findings are discussed in the light of test-related issues and implementation fidelity data.

Slow Down to Go Better: A Survey on Slow Feature Analysis.

Temporal data contain a wealth of valuable information, playing an essential role in various machine-learning tasks. Slow feature analysis (SFA), one of the most classic temporal feature extraction models, has been deeply explored in two decades of development. SFA extracts slowly varying features as high-level representations of temporal data. Its core idea of "slow" has been proven to be consistent with the nature of biological vision and beneficial in capturing significant temporal information for various tasks. So far, SFA has evolved into numerous improved versions and is widely applied in many fields such as computer vision, industrial control, remote sensing, signal processing, and computational biology. However, there currently lacks an insightful review of SFA. In this article, a comprehensive overview of SFA and its extensions is provided for the first time. The formulation and optimization of SFA are introduced. Two mainstream solutions, geometric interpretation, and a gradient-based training method of SFA are presented and discussed. Following that, a taxonomy of the current progress of SFA is proposed. We classify improved versions of SFA into six categories, including dual-input SFA (DISFA), online slow feature analysis (OSFA), probabilistic SFA (PSFA), multimode SFA, nonlinear SFA, and discrete labeled SFA. For each category, we illustrate its main ideas, mathematical principles, and applicable scenarios. In addition, the practical applications of SFA are summarized and presented. Finally, we bring new insights into SFA according to its research status and provide potential research directions, which may serve as a good reference for promoting future work.

An enhanced multi-objective artificial bee colony algorithm with non-dominated sorting strategy

<p>This paper presents an improved metaheuristic technique inspired by the foundational concepts of the artificial bee colony (ABC) algorithm adapted to deal with multi-objective optimization challenges. Our approach combines the main ideas of ABC with a non-dominated sorting strategy including aspects of Pareto dominance, crowding distance, and greedy selection method. Furthermore, the chosen non-dominated solutions are archived in a repository with a static size. The presented approach, multi-objective artificial bee colony (MOABC), is compared to other state-of-the-art algorithms including the non-dominated sorting genetic algorithm II (NSGA II) and the multi-objective particle swarm optimization (MOPSO). MOABC and selected algorithms from the literature are applied to five zitzler-deb-thiele (ZDT) Multi-objective benchmark functions. Then three key metrics are employed for performance evaluations: generational distance (GD), spread (SP), and hypervolume (HV). The simulation results suggest that the proposed method is competitive and presents an effective choice for tackling multi-objective optimization problems.</p>

Methodological aspects of investment and construction projects management based on IPD, BIM, LEAN. Foreign experience

Overexpenditure of cost and time resources is one of the most significant problems, and cost certainty is one of the key goals of the construction industry in Russia. Using the method of an analytical review of documents, the main problems of the European construction sector that exist in the process of its digital transformation were identified and characterized. Research has shown that the interdisciplinary synergy of BIM (Building Information Model, digital information model), Lean (lean manufacturing) and IPD (Integrated Project Delivery, integrated project execution) can benefit an investment and construction project (ICP) throughout its entire life cycle . However, such a synergetic approach is not currently applied in Russian projects. The article examines the impact of innovative international strategies for implementing COI and examines the obstacles to the implementation of these strategies in Russia.3 key takeaways:1) review of COI contracts to achieve the greatest synergy and increase trust between stakeholders;2) the BIM mandate is important to encourage the use of modern construction methodology in all ISPs in Russia;3) search for innovative methods of changing traditional thinking about construction.Consideration of three main ideas will accelerate the implementation of COI in Russia, leading to better results in the short, medium and long term for all stakeholders.

Dominasi Layar di Masa Pandemi dalam terang Pemikiran Anne Friedberg

Screen allows humans to experience and understand the world without being limited by the existence of their physical body. This is one of Anne Friedberg's main ideas in her works, which supports the main basis for this article. The Covid-19 pandemic that has occurred since March 2020 has limited, reduced, slowed down, and in some situations it could even be said it almost stopped human mobility, for example, in areas over the world where the ‘lockdown’ policy was applied. As a consequence, mobility turns into immobility. This condition corresponds to the reality during the pandemic dominated by the presence of screen. There has been growing importance of domestic space as the centre of everydayness that gives crucial role to the screen as its window to the world. This could be perceived as virtual mobility, in the sense that it was a ‘mobility’ without bodily mobility. This article elaborates Friedberg's thoughts with regard to virtual mobility that has been increasingly dominated by the screen, by examining its relevance to the actual conditions of the people during the pandemic. At the end of this article, the consequences of this massive virtual mobility and screen dominance during the pandemic are analysed—a situation that might bring further implications on the experiences of aura, panopticon, and consumption.

Prinsip Keadilan dan Kebebasan dalam Pemikiran Ekonomi M. Umer Chapra

This research was motivated by researchers' interest in the figure of Umer Chapra as one of the leading figures in Islamic economics and finance. One of Chapra's deep and critical ideas is about usury or bank interest which he put into a small book entitled "Prohibition of Interest: Does it make sense?". This work was quite "impressive" for Chapra because it was written at the request of many people who wanted to see Chapra's critical review regarding bank interest. This research aims to examine various main ideas that dominantly exist in Chapra's economic thinking in the book "The Prohibition of Interest". This research is a study with a qualitative paradigm and is also included in library research. The primary source for this research was obtained from Chapra's original work, while the secondary source came from the works of other people who studied Chapra's thinking, both from research, book reviews and other articles. There are various interesting views discussed by Chapra on economic problems. However, overall, it is revealed that Chapra's thinking in an economic context basically carries the principles of justice and freedom, as part of the principles of Islamic economics.

A regularity result for the free boundary compressible Euler equations of a liquid

We derive a priori estimates for the compressible free boundary Euler equations in the case of a liquid without surface tension. We provide a new weighted functional framework which leads to the improved regularity of the flow map by using the Hardy inequality. One of main ideas is to decompose the initial density function. It is worth mentioning that in our analysis we do not need the higher order wave equation for the density.

Traditions of French Constitutionalism in Polish Constitutional Thought

The influence of French constitutionalism on the Polish legal order is still present in the studies and analyses of the doctrine of constitutional law. Indeed, the French constitutional tradition forms part of the European legal heritage to which the founders of Polish statehood readily referred. The present text outlines the main thoughts and ideas which, over a period of more than two hundred years – from the second half of the 18th century to the present day – have influenced the constitutional shape of the Polish state either by way of recapitulating or negating various institutional solutions.

Psychotherapy of the oppressed: the education of Paulo Freire in dialogue with phenomenology

ABSTRACT The current paradigm of mental health has fallen short in its promises to deliver better care and quality of life for those who lives with mental illness. Recent works have expressed the need for more comprehensive frameworks of research, in which phenomenology emerges as a fundamental tool for a new wave interdisciplinary studies with the humanities. In line with this project, this article hopes to explore the relation between education and phenomenologically oriented psychotherapy, through the work of Brazilian educator Paulo Freire. First, we will briefly expose Freire’s biography and main ideas (such as the “banking model of education” and the creation of “culture circles”), showing how they can be useful during the clinical encounter. We will also highlight the importance of dialogical psychotherapy during situations of injustice and oppression. Finally, we will provide some insights that can help build a new paradigm of mental health that is based on a “praxis of freedom”, whether in research or clinical practice. We call this proposal a “Psychotherapy of the Oppressed”.

The Social and Political Thought of Sayyed ʿ⁠Ali Moḥammad Širāzi, the Bāb

Abstract Sayyid ʿ⁠Ali Muḥammad Širāzi (1819–50), known as “the Bāb”, is one of the most important modernizers of the 19th century in Iran. He is one of the first thinkers, within the Islamic thought’s modern framework, who challenged the forces of tradition such as the Shiite clergy and the Persian absolute monarchy by offering a new religious view, which went beyond Islamic religion. This article, after a brief reconstruction of the intellectual biography of the Bāb, will analyse his social and political thought, highlighting his main ideas regarding the role of rationality; the role of education and pedagogy; the economy and industrialization; the environment and the importance of civic cohabitation. The article will focus on Bāb’s views concerning the role of the women in the society and the abolition of the clergy from the religious sphere. This work will also show how Bāb’s thought contributed, together with secular and Islamic reformist intellectuals, to the Iranian constitutional revolution (Mašrūṭe) in the early 20th century.

Preface

Preface The present volume constitutes the proceedings of the First workshop on Soliton Theory, Nonlinear Dynamics and Machine Learning held in Varna (Bulgaria) from 12 to 17 August 2023 which is organized by the Institute for Advanced Physical Studies (Bulgaria) and the Institute for Physical and Mathematical Studies of the Varna Free University (VFU).The purpose of the workshop was to bring together qualified scientists, young researchers and students with expertise and interests in mathematics and physics. In this way the workshop was intended to offer an opportunity to discuss recent developments and achievements, as well as future perspectives in these modern and fast developing areas and their interface.Contemporary science, mainly due to its complexity, uses more and more elaborate techniques and methods, thus achieving sometimes amazing results. The numerous conferences often involve large number of scientists which should be able to explain their results in rather short time. Hence, only a limited number of participants, who already have mastered the relevant field, are able to understand these results. A beginner in the field has practically no chances to understand which are the main ideas and techniques in it. Our aim with this workshop was to avoid these difficulties and to help a group of beginners do their start in science. In order to achieve practical results with our Workshop to have more young people as participants. Every speaker had 45 minutes for presentation and 15 minutes for questions and discussions. This is an ample time to explain in detail the main ideas in the talk so that even a beginner could understand it. In addition there was extra time during the coffee and lunch breaks for contacts among the people on site. Of course for the online participants this was more difficult, though they were given optimal chances to ask questions during and after the reports.It is our belief that in such atmosphere the beginners will have the best chance to understand a certain subject and get introduced to a given scientific field. During the Workshop we had 28 reports (see the list of reports and the list of participants). Some of the younger participants were also given the chance to report on their results and to gain experience for their future participation in conferences.The workshop greatly benefited from the dedicated involvement of the renowned experts in their fields of science Vladimir Gerdjikov (Institute of Mathematics and Informatics, Bulgarian Academy of Sciences), Peter Hristov (CERN), Radu Constantinescu (University of Craiova, Romania), Rossen Ivanov (Technological University Dublin, Ireland), Stoytcho Yazadjiev (St. Kliment Ohridski University of Sofia, Bulgaria) who were the scientific committee members.We would like to thank the President of VFU Dr. Krasimir Nedyalkov and the Rector of VFU Prof. Dr. Peter Hristov for the collaboration and continuous attention.The success of every conference is based on the activity and the competence of its participants. We are grateful to all participants for their efforts to produce high quality reports and for their activity in the discussions after every talk.The Workshop was held at the VFU campus, close to the Black Sea with the financial support of the Bulgarian National Science Fund contract BG-175467353-2023-02-0006 and Varna Free University.The Editors:R. Constantinescu, V. Gerdjikov, S. Mishev, S. YazadjievList of Scientific Committee, Local Organizing Committee are available in this pdf.

On the reasons for the removal of A.T. Tvardovsky from the position of head of the editorial office of the magazine “New World”

The subject of the article is the activities of the “New World” journal in the 1950-1960s. The author examines the role of the magazine at the beginning of the reform of Russian literature; the position of the editor-in-chief of “New World” regarding the function of literature designed to reflect reality; the reasons why A. Tvardovsky was removed from the post of editorial director. The work indicates that A. Tvardovsky served as editor-in-chief of the “New World” for 16 years, but during his career he faced dismissal twice. The article reflects the direction and main ideas of liberal thought of the New World magazine, which in the 1950s and 1960s was under the leadership of the editor-in-chief A. Tvardovsky. When studying the problems associated with the magazine’s position on the need to provide literary creativity with a certain freedom. When considering the activities of the magazine and its editor in certain historical and sociocultural conditions, a comparative historical method was used. The main conclusion of the study is that A. Tvardovsky, through his activities as editor-in-chief of the publication “New World” and his principled position on the freedom of literary creativity, made it possible to outline the beginning of the Thaw period in the Soviet literary process. The novelty of the research lies in the fact that the article systematizes information about the reasons for the removal of A. Tvardovsky from the post of editorial director and proves the role of the periodical in question in the process of making a turn in Russian literature towards the realistic tradition. A. Tvardovsky even published those works that were rejected by other leading journals due to the discrepancy between the author’s ideas and the ideas of the ruling party.
