Authors: Olszowy-Tomczyk Małgorzata , Paprotny Łukasz , Celejewska Agnieszka , Szewczak Dorota , Wianowska Dorota 
Published: June 2021

Abstract
The imbalance between the production of Reactive Oxygen Species (ROS) and their sequestration promotes the formation of so-called oxidative stress conditions which are considered crucial in the aging process and development of many human diseases. Glutathione plays an essential role in the antioxidative barricade against ROS. Its role in the detoxification process of xenobiotics and carcinogen is also known. However, there are no comparative studies on the antioxidant properties of both biological samples and glutathione as well as the change in these properties as a result of exposure to various stress factors. This paper fills this gap comparing the antioxidant activity of serum and plasma samples of the known glutathione content with the activity of glutathione itself assessed by the different methods. In addition, it reveals a significant role of environmental xenobiotics in oxidative stress and differentiates the stress induced by different groups of drugs, among which the greatest one has been demonstrated for antiarrhythmic drugs and cytostatics. More importantly, it proves that human plasma is more resistant to stress factors and N-acetylcysteine clearly promotes the extension of antioxidant properties of both the plasma and serum samples. The latter conclusion is consistent with the implied preventive and/or supportive action of this drug against SARS-CoV-2.
Social Media Monitoring of the COVID-19 Pandemic and Influenza Epidemic With Adaptation for Informal Language in Arabic Twitter Data: Qualitative Study
Authors: Alsudias Lama , Rayson Paul 
Published: June 2021

Background
Twitter is a real-time messaging platform widely used by people and organizations to share information on many topics. Systematic monitoring of social media posts (infodemiology or infoveillance) could be useful to detect misinformation outbreaks as well as to reduce reporting lag time and to provide an independent complementary source of data compared with traditional surveillance approaches. However, such an analysis is currently not possible in the Arabic-speaking world owing to a lack of basic building blocks for research and dialectal variation.

Objective
We collected around 4000 Arabic tweets related to COVID-19 and influenza. We cleaned and labeled the tweets relative to the Arabic Infectious Diseases Ontology, which includes nonstandard terminology, as well as 11 core concepts and 21 relations. The aim of this study was to analyze Arabic tweets to estimate their usefulness for health surveillance, understand the impact of the informal terms in the analysis, show the effect of deep learning methods in the classification process, and identify the locations where the infection is spreading.

Methods
We applied the following multilabel classification techniques: binary relevance, classifier chains, label power set, adapted algorithm (multilabel adapted k-nearest neighbors [MLKNN]), support vector machine with naive Bayes features (NBSVM), bidirectional encoder representations from transformers (BERT), and AraBERT (transformer-based model for Arabic language understanding) to identify tweets appearing to be from infected individuals. We also used named entity recognition to predict the place names mentioned in the tweets.

Results
We achieved an F1 score of up to 88% in the influenza case study and 94% in the COVID-19 one. Adapting for nonstandard terminology and informal language helped to improve accuracy by as much as 15%, with an average improvement of 8%. Deep learning methods achieved an F1 score of up to 94% during the classifying process. Our geolocation detection algorithm had an average accuracy of 54% for predicting the location of users according to tweet content.

Conclusions
This study identified two Arabic social media data sets for monitoring tweets related to influenza and COVID-19. It demonstrated the importance of including informal terms, which are regularly used by social media users, in the analysis. It also proved that BERT achieves good results when used with new terms in COVID-19 tweets. Finally, the tweet content may contain useful information to determine the location of disease spread.

Getting Emotional
Authors: Djordjevic Charles 
Published: June 2021

This paper aims to demonstrate the fecundity of pairing specific insights from On Certainty with research in the philosophy and history of the natural sciences. To do so, it discusses one set of related themes in the work that focus on the possibility of and nature of revolutionary change. Specifically, I argue that several of Wittgenstein’s rather gnomic remarks presage van Fraassen’s insistence on the need for decisions and emotions throughout scientific revolutions. Moreover, I argue that reading both together enriches each’s individual account and helps further make sense of why and how conversion is not just a ‘mad leap in the dark’.
The Epistemology of Psychology from a Perspective of Wittgenstein’s Grammatical Analysis
Authors: Donat Mirian 
Published: June 2021

This article evaluates Wittgenstein’s possible contributions to an epistemology of psychology. Although the author admittedly neither proposes an epistemology nor examines specific issues of psychology as a science, we understand that his reflections on the meaning of psychological concepts may contribute to a better understanding of psychology as a science, which involves understanding its object and methods. With that goal in mind and based on the concept of language developed in his second phase, especially in his work Philosophical Investigations, we retrace his efforts to obtain a picture of the grammar of psychological concepts, emphasizing two of its aspects: first, the place and role of first‑person expressive propositions in the psychological language-game and second, how this understanding of the perspective of the first person implies in refusing to reduce explanations of human behavior to causal explanations in favor of explanations based on reasons.
Paradigm and Objectivity in the Sciences
Authors: Gottschalk Cristiane 
Published: June 2021

The concept of paradigm became, in the middle of the last century, a central concept in the philosophical discussion about the nature of scientific knowledge. However, little attention has been paid to the strength of this concept in the constitution of the senses in general and, in particular, about its role in the transmission and acquisition of new scientific concepts, not only in the community of scientists, but also among basic-science teachers and students. I argue that a Wittgensteinian-inspired reflection on the transcendental use of this concept, as part of the grammar of scientific concepts, can clarify not only fundamental questions about the nature of scientific activity (avoiding both dogmatic and relativistic conceptions), but can also provide us with clues to identify sufficient, though not necessary, conditions so that something becomes an object for scientific thinking in the context of school education.
Scientific Representation, Causality and Induction in L. Wittgenstein’s Tractatus
Authors: Simões Eduardo 
Published: June 2021

The purpose of this article is to demonstrate how the Wittgenstein Tractatus deals with themes related to the laws of nature, as well as with the metatheoretical principles of science. More specifically, our intention is to expose the notions of scientific representation linked to principles such as those of causality and induction. As a starting point, we propose that the notion of non-precedence of one scientific theory over another is of Hertzian inspiration, which argues that “one image may be more suitable for one purpose, another for another” (HERTZ, 1956, p. 3). As an unfolding of this notion, the systems of geometric representation of Hertz and Boltzmann will serve the Tractatus in order to demonstrate that laws, like the law of causality, as form and not content, only represent the network (any method) that, after all, is optional. On the other hand, metatheoretical principles such as induction have no logical basis and their effect, in the wake of what Hume thought, is only psychological. Like the other themes of the Tractatus, its Philosophy of Science cannot be understood outside a broader context, which is the proper context to the criticism of language. Therefore, what is presented here intends not to be divorced from the relationship between logic, language and science, since, in our view, these are the three pillars of support of the Tractatus Logico-Philosophicus.
Kuhn and Wittgenstein
Authors: Oliveira Wagner 
Published: June 2021

For dropping the incommensurability idea elaborated at the time of The Structure of Scientific Revolutions, Kuhn dismisses the concept of “revolution”. The incommensurability involved the incomparability of theories. In this new environment, the revolution is replaced by conceptual reformulation and the incommensurability becomes occasional. The linguistic turn in Kuhn’s thought involves conceptual changes whose aim is to get around the accusation of relativism that the former notion of incommensurability arouses. The most fundamental effect of these conceptual reformulations is the commitment to a traditional conception of semantics. It changes the comprehension of the historical and social nature of the foundations of the changes that scientific knowledge goes through. The comparison between the answer to the problem of paradigm priority attributed by Kuhn to Wittgenstein and Wittgenstein by himself shows that the basis of the normative nature of paradigm commitment is an essentialist concern. In the second half of this paper, I will evaluate Kuhn’s manner of getting around the problems of incommensurability in contrast to Wittgenstein’s view of philosophy dealing with similar issues in On Certainty. This enables one to essay answers to the problems of incommensurability without relativism or any commitment to a traditional conception of semantics. These contrasts show how far Kuhn’s new theory of science departs from the Wittgensteinian inspiration and abandons the point of view of The Structure of Scientific Revolutions. The development of these two halves makes it possible to indicate reasons to believe that questions concerning the theory and history of science can benefit largely from a grammatical exploration, which gives rise to a theory of science inspired by Wittgenstein’s thought, as Mauro Condé suggests.
