The novel coronavirus is an infectious disease that spread across the world, bringing with it serious mental health problems for men and women. Women in Pakistan are infected with COVID-19 at a much lower rate than men, yet report worse mental health. To explain this paradox, we surveyed 190 participants shortly following the country lockdown, focusing on perceptions of the COVID-19 impact and positive adjustment. Measures used in this study included the Warwick-Edinburgh Mental Well-being Scale and Distress Tolerance Scale. Factor (...) analysis revealed five distinct areas related to COVID-19, which did not differ by sex. However, men reported higher levels of both distress tolerance and well-being than women. High endorsement of actions to protect against COVID-19 was related to lower distress tolerance scores, but in different ways for men and women. Men, but not women, who endorsed more protective measures to stop the pandemic reported higher DTS absorption scores, and therefore being more consumed by distress; women who endorsed more protective measures to stop the pandemic reported less acceptance of distress than men, as reflected in DTS appraisal scores. An in-depth analysis of women’s beliefs and behaviors related to COVID-19 is warranted to understand why Pakistani women who are infected with COVID-19 at lower rates than men show more mental health symptoms.

The genetic code is a set of instructions that determine how the information in our genetic material is translated into amino acids. In general, it is universal for all organisms, from viruses and bacteria to humans. However, in the last few decades, exceptions to this rule have been identified both in pro‐ and eukaryotes. In this review, we discuss the 16 described alternative eukaryotic nuclear genetic codes and observe theories of their appearance in evolution. We consider possible molecular mechanisms that (...) allow codon reassignment. Most reassignments in nuclear genetic codes are observed for stop codons. Moreover, in several organisms, stop codons can simultaneously encode amino acids and serve as termination signals. In this case, the meaning of the codon is determined by the additional factors besides the triplets. A comprehensive review of various non‐standard coding events in the nuclear genomes provides a new insight into the translation mechanism in eukaryotes. (shrink)

Objective To develop an ethically, legally, and clinically appropriate ventilator allocation policy for AdventHealth Tampa and AdventHealth Carrollwood in Tampa, Florida, which could be enacted swiftly during the Covid-19 pandemic. Methods During Spring 2020, a subcommittee of the Medical Ethics Committee established consensus on the fundamental principles of the policy, then built on existing ethical, legal, and clinical guidance. Results The plan was finalized in May 2020. The plan triages patients based on exclusion criteria, prognosis and expected benefit of ventilation, (...) and change in prognosis over time. Decisions are made by committee in order to minimize moral distress among individual patient care providers. Conclusions Due to international concerns about healthcare resource shortages during the Covid-19 pandemic, hospitals need allocation policies informed by the crisis standard of care, the hospital’s ethical duty to plan for an emergency, and federal civil rights laws Policy Implications: This type of policy can serve as a model for other institutions to develop crisis standards of care resource allocation policies, which are a necessary component of disaster planning.

The rapid increase in COVID-19 cases has become the symbol of fear, anxiety, and panic among people around the globe. Mass media has played an active role in community education by addressing the health information of this pandemic. People interact by sharing their ideas and feelings through social media platforms. There is a considerable need to implement different measures and better perceive COVID-19 pertinent facts and information by demystifying public sentiments. In this study, the Quarantine Life dataset of thousand tweets (...) is based on #Quarantine, #Quarantine Days, #Quarantine Life, #My Pandemic Plan, and #Quarantine and Chill from January to September 2020 has been collected from Twitter. The extracted data have been scrubbed through preprocessing techniques. The sentiments and topics extracted from tweets have been analyzed through the TEXT BLOB, VADER, and AFFIN approach. Results show that people were distressed and fearful due to the COVID-19 pandemic. However, most people enjoyed by playing games, watching movies, and reading books during the lockdown period. According to the present meta-analysis, physical activity interventions are beneficial for patients with dementia in terms of cognition. The proposed framework illustrates the insight impact of COVID-19 on human physiological and mainly focuses on the evaluation of sentiment dynamics at the topical level. (shrink)

Though in these studies they have been discussed from different respects, none of them draws attention to the place and importance of the theory of shadows (aẓilla) in the esoteric sects. In this article, after the identification of the meaning of the theory of shadows, it has been argued that the concept of shadows has a central role in understanding the esoteric system of thought. In this context, it has been tried to reveal the central effect of the theory of shadows on the basic ideas of esoteric sects. The theory of shadows can be defined as the reflection of the shadows or non-material beings, which appear in the divine world, in this world in a material form. The origins of this view go back to the Plato’s theory of ideas that he formulated as ideas and forms and to his allegory of cave that he used to explain this theory. This theory which was formulated and developed by the pre-Islamic various religious and philosophical traditions took an Islamic form through the bāṭinī/esoteric schools. The theory of shadows was first developed by the extremist groups of shiʿa. Though the early classical works referred the theory of shadow to the extremist shiʿas, they do not give any detail thereof. Nevertheless, it is possible to find in some views of theirs and in the esoteric sects such as Ismailites, Nusayrites, Druzes and Yazidites some clues about the character of this theory. In addition, the later works like Kitāb al-Haft wa al- ʾAẓilla directly articulating the theory of shadows were composed. Although the theory of shadows was not mentioned sufficiently in the works produced within the bāṭinī/esoteric circles, it is witnessed that their understandings of religion were based, to a large extent, upon the theory of shadows. The most basic feature of this unnamed understanding is the claim that every being in the divine world has been reflected in this world in a material form. Since the essence of God generally was kept out from the manifestation (tajallī), reflection was not started with his essence. However, the first beings emanating from Almighty Creator brought the divine world into being and that world was reflected to this world in a material form. With this perception, a Gnostic understanding was developed that the material has no reality and the ultimate reality should be sought in the non-material. According to this, the material beings consisting of only reflection of reality are not possible to have an ultimate reality. The only truth is the meaning, inner (bātin) or shadow which reflects to the world in a material form. Naturally what a bāṭinī should do is to seek the non-material ultimate truth hidden behind the material form. The theory of shadows in this point argued compulsorily the distinction of ẓāhir-bātin (outer-inner). Accordingly, ẓāhir consists of a shell or reflection in which hides the truth. The duty one should do is to go beyond the outer meaning of religious text and to get the inner truth hidden behind the outer meaning. The theory of shadows made a dualist view point obligatory, because every being has an inner aspect which includes the truth and an outer respect in which the ultimate truth is reflected in a material form. God has the inner attributes through which the truth appears spiritually and material attributes to which they are reflected. Universe has a dualist character, a spiritual universe consisting of non-material realities and material universe consisting of its reflections. Human beings have a dualist character, a soul belonging to the divine world and a body belonging to this world. Religious texts which were sent for the salvation of mankind also have two aspects, the inner (bāṭin) belonging to the divine world and the outer (ẓāhir) belonging to this world. Since the Bāṭiniyya considered the divine world to be composed of sevenfold and each fold to be a divine being, they sought, as a result of the theory of shadow, to find in the material world the counterparts or reflections of these beings. Even if their names show differences, the bāṭinī/esoteric groups regarded in certain times some figures as the reflections of the divine world in the material world. Divine beings called al-ʿAql al-Kullī (the Universal Intellect), al-Nafs al-Kullī (the Universal Soul), al-Kalima, Sābiq and Tālī were reflected in the world as the material forms like the Prophet Muhammad, Ali, Salman al-Farisī, Miqdāt b. al-Aswad, Ammār b. Yāsir. This understanding resulted in the divinization of some figures in the world, because it was held that through the manifestation these figures differ from the ordinary people, thus having some divine features. These figures gaining a bipolar identity were outwardly human beings, while inwardly regarded as the forms of divine beings reflected in the world. In this point, what the other people should do is to comprehend, with reference to the figures and their forms, the divine truth reflecting them. This approach brought about a religious understanding in which an individual salvation was not possible and some figures were perceived as charismatic leaders. As a result, the religious understanding developed by the Bāṭiniyya schools is under the ultimate influence of the theory of shadows. With reference to this theory, they developed a new understanding of Islam called Esotericism. At the core of this perception lies the theory of shadows and dualism as its inseparable part. In this sense, Esotericism represents a religious understanding developed in this direction and having a wholeness and deepness. In order to understand this religious understanding correctly, the theory of shadows must be taken into consideration and the esoteric texts be read in this direction. This kind of way of reading, in which the outer is seen as the unique reality, fails to realize the duality behind it, will not enable us to comprehend the inner wholeness of Esotericism and cause to see it as a mass of contradictions.

Several novel approaches have been proposed to resolve the problem of time by relating it to change. We argue using quantum information theory that the Hamiltonian constraint in quantum gravity cannot probe change, so it cannot be used to obtain a meaningful notion of time. This is due to the absence of quantum Fisher information with respect to the quantum Hamiltonian of a time-reparametization invariant system. We also observe that the inability of this Hamiltonian to probe change can be related (...) to its inability to discriminate between states of such a system. However, if the time-reparametization symmetry is spontaneously broken due to the formation of quantum cosmological time crystals, these problems can be resolved, and it is possible for time to emerge in quantum gravity.

Therapeutic landscapes encapsulate healing and recovery notions in natural and built environmental settings. Tourists’ perceptions determine their decision making of health and wellness tourism consumption. Researchers struggle with the conceptualization of the term ‘therapeutic landscapes’ across disciplines. Drawing on extant literature searched in nine databases, this scoping review identifies different dimensions of therapeutic landscapes. Out of identified 178 literature sources, 124 met the inclusion criteria of identified keywords. We review the contribution and the potential of environmental psychology in understanding tourist (...) behavior to promote health and wellness tourism destinations in a post COVID-19 context. We develop and propose a conceptual framework comprising: perceived goodness of therapeutic landscapes, health and wellness consumption, COVID-19 pandemic perceived health and wellness risk, place attachment, and re-visitation. We propose measurement scales and discuss implications and major issues in the immediate and post the COVID-19 pandemic to inform future research. (shrink)

AbstractIslam's Quantum Question by Nidhal Guessoum offers a sophisticated approach to reconciling the results of modern science with Islamic tradition. The book provides a valuable critique of existing literature on Islam and science and advocates the promotion of good science and science education in the Muslim world. A central tension in the book revolves around Guessoum's efforts to promote a version of theistic science, while at the same establishing a clear boundary for science and scientific methodology. Although the latter works (...) very well, the project of theistic science presented in the book is, at the very least, contentious. However, Islam's Quantum Question is a milestone in the literature on Islam and science and should be valuable for anyone interested in the search for meaning in both science and religion. (shrink)

To a modern observer of Western culture, Romanticism might appear conflicted about size. On the one hand, the likes of Chopin and Scriabin best expressed themselves through small-scale compositions, while, on the other, there were those who, like Wagner and Mahler, produced colossal works. The aim of the present article is to explore the phenomenon of miniaturization in Western culture and to examine how miniature works (e.g., literary fragments, preludes) competed with their much larger counterparts. My central claims are threefold: (...) (1) that miniaturization, contrary to common belief, is not a contemporary phenomenon; (2) that the attitude of Romanticism to size was not paradoxical but rather an attempt to harmonize the fragment and the colossal; and (3) that in contemporary culture, the fragment and the colossal are no longer in harmony with each other.

In the chapter “Information and Content” of their Impossible Worlds, Berto and Jago provide us with a semantic account of information in deductive reasoning such that we have an explanation for why some, but not all, logical deductions are informative. The framework Berto and Jago choose to make sense of the above-mentioned idea is a semantic interpretation of Sequent Calculus rules of inference for classical logic. I shall argue that although Berto and Jago’s idea and framework are hopeful, their definitions (...) do not capture what is intended. This is so because the definitions are solely based on the logical complexity of an argument and they fail to capture the richness of the non- logical content of that argument. Then I will suggest some amendments to address this problem. Finally, I will extend the application of the definitions to first-order logic. It shall be observed that in some classical deductions, applying contraction may lead to hiding some epistemic impossibilities. This happens when formulae which contribute different propositions to the proof get contracted at the quantified level. (shrink)

This is a contribution to the idea that some proofs in first-order logic are synthetic. Syntheticity is understood here in its classical geometrical sense. Starting from Jaakko Hintikka’s original idea and Allen Hazen’s insights, this paper develops a method to define the ‘graphical form’ of formulae in monadic and dyadic fraction of first-order logic. Then a synthetic inferential step in Natural Deduction is defined. A proof is defined as synthetic if it includes at least one synthetic inferential step. Finally, it (...) will be shown that the proposed definition is not sensitive to different ways of driving the same conclusion from the same assumptions. (shrink)

In the Buddhist tradition, there is an expansive collection of texts that explore the topic of ethics, addressing moral questions concerning the right and wrong behaviors, virtues, vices, and so forth. However, when examining the main texts of this tradition, we find an absence of a structured moral philosophy that systematically and critically analyzes moral values and principles. Therefore, Buddhist scholars have responded in different ways to the perplexing situation in which Buddhism largely lacks an explicit theory in moral philosophy. (...) Some scholars argue that we should read Buddhist moral teachings as one of the contemporary ethical theories, such as consequentialism or virtue ethics. Damien Keown is one of the scholars who claims that “virtue ethics” is the best way to understand Buddhist ethics. This paper analyzes and critiques Damien Kewon’s reading of Buddhist moral teachings as Virtue ethics. I argue that such interpretation poses problems, primarily because it may overlook key aspects of Buddhist beliefs deemed inconsequential to contemporary ethical debates, and secondly, it could result in the imposition of non-authentic Buddhist ideas on Buddhist ethics.

This thesis is about how deduction is analytic and, at the same time, informative. In the first two chapters I am after the question of the justification of deduction. This justification is circular in the sense that to explain how deduction works we use some basic deductive rules. However, this circularity is not trivial as not every rule can be justified circularly. Moreover, deductive rules may not need suasive justification because they are not ampliative. Deduction preserves meaning, that is, the (...) meaning of non-logical vocabulary of any theory which is developed by deductive reasoning remains unchanged. It means that deduction adds no information to what we already had in our premises. This is why deduction is analytic. -/- However, there are many ways deduction can be informative. In the next three chapters, I will pick a specific kind of deductive reasoning, namely arithmetical reasoning, and will attempt to understand the nature of information we obtain by this kind of reasoning. There is a difference between simple deductive moves such as inferring `Socrates is mortal' from `All human are mortal' and `Socrates is human', and inferring that a relation is reflexive given that it is directed, symmetric and transitive. The latter is more complicated and not as easy to prove as the former. Therefore it is informative and the proof we construct to prove it puts us in an epistemic position that we were not in before having the proof. To be more specific, I show that concepts we need to confirm the conclusion are made in the process of proving the conclusion. (shrink)

Aristotle (b. 322 BC) was the first philosopher in the history of thought to examine all modes and types of belief acquisition such as knowledge, supposition, error and indirectly imagination. In his _Prior Analytics_, which he wrote primarily to clarify his theory of demonstration, Aristotle examined in detail the syllogism, which he saw as the most important form of reasoning, and his analysis was subject to interpretation by different traditions of thought for centuries. Aristotle’s _Prior Analytics_ was translated into Arabic (...) in the classical period and later interpreted by many Islamic logicians. This article aims to show how Aristotle’s definition of the syllogism in the _Prior Analytics_ was taken up and interpreted in the Peripatetic Islamic logical tradition. These interpretations of the definition of the syllogism will provide us with an idea about the unique features of the commentaries on the _Prior Analytics_ in the Islamic world. Here, introductory information about the translation of the _Prior Analytics_ into Arabic and its commentators in Arabic will be given, Aristotle’s definition of the syllogism and its versions in Peripatetic Islamic logicians will be indicated, and the interpretation of the basic terms in the definition by Peripatetic Islamic logicians will be revealed.

Spam electronic mails (emails) refer to harmful and unwanted commercial emails sent to corporate bodies or individuals to cause harm. Even though such mails are often used for advertising services and products, they sometimes contain links to malware or phishing hosting websites through which private information can be stolen. This study shows how the adaptive intelligent learning approach, based on the visual anti-spam model for multi-natural language, can be used to detect abnormal situations effectively. The application of this approach is (...) for spam filtering. With adaptive intelligent learning, high performance is achieved alongside a low false detection rate. There are three main phases through which the approach functions intelligently to ascertain if an email is legitimate based on the knowledge that has been gathered previously during the course of training. The proposed approach includes two models to identify the phishing emails. The first model has proposed to identify the type of the language. New trainable model based on Naive Bayes classifier has also been proposed. The proposed model is trained on three types of languages (Arabic, English and Chinese) and the trained model has used to identify the language type and use the label for the next model. The second model has been built by using two classes (phishing and normal email for each language) as a training data. The second trained model (Naive Bayes classifier) has been applied to identify the phishing emails as a final decision for the proposed approach. The proposed strategy is implemented using the Java environments and JADE agent platform. The testing of the performance of the AIA learning model involved the use of a dataset that is made up of 2,000 emails, and the results proved the efficiency of the model in accurately detecting and filtering a wide range of spam emails. The results of our study suggest that the Naive Bayes classifier performed ideally when tested on a database that has the biggest estimate (having a general accuracy of 98.4%, false positive rate of 0.08%, and false negative rate of 2.90%). This indicates that our Naive Bayes classifier algorithm will work viably on the off chance, connected to a real-world database, which is more common but not the largest. (shrink)

Scientists cannot devise theories, construct models, propose explanations, make predictions, or even carry out observations, without first classifying their subject matter. The goal of scientific taxonomy is to come up with classification schemes that conform to nature's own.

The interest in ascertaining the real kinds of things in nature is as old as philosophy itself, but it takes on a different guise when one (...) adopts a naturalist stance in philosophy, that is when one looks closely at scientific practice and takes it as a guide for identifying natural kinds and investigating their general features.

ABSTRACT Introduction: Informed consent has been recognized as an important component of research protocols and procedures of disclosure and consent in collaborative research have been criticized, as they may not be in keeping with cultural norms of developing countries. This study, which is part of a larger project funded by the United States National Bioethics Advisory Commission, explores the opinions of developing country researchers regarding informed consent in collaborative research. Methods: A survey of developing country researchers, involved in human subject (...) research, was conducted by distributing a questionnaire with 169 questions, which included questions relating to informed consent. In addition, six focus group discussions, eight in‐depth interviews and 78 responses to open‐ended questions in the questionnaire provided qualitative data. Results: 203 surveys were considered complete and were included in the analysis. Written consent was not used by nearly 40% of the researchers in their most recent studies. A large proportion of respondents recommended that human subject regulations should allow more flexibility in ways of documenting informed consent. 84% of researchers agreed that a mechanism to measure understanding should be incorporated in research studies as part of the process of informed consent. Discussion: This paper is an empirical step in highlighting the ethical issues concerning disclosure. Health researchers in developing countries are well aware of the importance of consent in health research, and equally value the significance of educating human subjects regarding study protocols and associated risks and benefits. However, respondents emphasize the need for modifying ethical regulations in collaborative research. (shrink)

In “Compassionate Phenomenal Conservatism” (2007), “Phenomenal Conservatism and the Internalist Intuition” (2006), and Skepticism and the Veil of Perception (2001), Michael Huemer endorses the principle of phenomenal conservatism, according to which appearances or seemings constitute a fundamental source of (defeasible) justification for belief. He claims that those who deny phenomenal conservatism, including classical foundationalists, are in a self-defeating position, for their views cannot be both true and justified; that classical foundationalists have difficulty accommodating false introspective beliefs; and that phenomenal conservatism (...) is most faithful to the central internalist intuition. I argue that Huemer’s self-defeat argument fails, that classical foundationalism is able to accommodate fallible introspective beliefs, and that classical foundationalism captures a relatively clear internalist intuition. I also show that the motivation for phenomenal conservatism is less than clear. (shrink)

Visual cryptography is a cryptographic technique that allows visual information to be encrypted so that the human optical system can perform the decryption without any cryptographic computation. The halftone visual cryptography scheme (HVCS) is a type of visual cryptography (VC) that encodes the secret image into halftone images to produce secure and meaningful shares. However, the HVC scheme has many unsolved problems, such as pixel expansion, low contrast, cross-interference problem, and difficulty in managing share images. This article aims to enhance (...) the visual quality and avoid the problems of cross-interference and pixel expansion of the share images. It introduces a novel optimization of color halftone visual cryptography (OCHVC) scheme by using two proposed techniques: hash codebook and construction techniques. The new techniques distribute the information pixels of a secret image into a halftone cover image randomly based on a bat optimization algorithm. The results show that these techniques have enhanced security levels and make the proposed OCHVC scheme more robust against different attacks. The OCHVC scheme achieves mean squared error (MSE) of 95.0%, peak signal-to-noise ratio (PSNR) of 28.3%, normalized cross correlation (NCC) of 99.4%, and universal quality index (UQI) of 99.3% on average for the six shares. Subsequently, the experiment results based on image quality metrics show improvement in size, visual quality, and security for retrieved secret images and meaningful share images of the OCHVC scheme. Comparing the proposed OCHVC with some related works shows that the OCHVC scheme is more effective and secure. (shrink)

Over the previous three decades, the area of computer networks has progressed significantly, from traditional static networks to dynamically designed architecture. The primary purpose of software-defined networking is to create an open, programmable network. Conventional network devices, such as routers and switches, may make routing decisions and forward packets; however, SDN divides these components into the Data plane and the Control plane by splitting distinct features away. As a result, switches can only forward packets and cannot make routing decisions; the (...) controller makes routing decisions. OpenFlow is the communication interface between the switches and the controller. It is a protocol that allows the controller to identify the network packet’s path across the switches. This project uses the SDN environment to implement the firefly optimization algorithm to determine the shortest path between two nodes in a network. The firefly optimization algorithm was implemented using Ryu control. The results reveal that using the firefly optimization algorithm improves the selected short path between the source and destination. (shrink)

ABSTRACTGenetic testing results and research findings raise concerns about access to genetic information by insurers. Recently, the Canadian Life and Health Insurance Association reaffirmed its prerogative to request, for underwriting purposes, the disclosure of clinical and research genetic test results if the participant/patient or his physician has knowledge of the results. Studies have shown that access to genetic information to determine insurability can, in limited instances, lead to actual, or fear of, genetic discrimination, result in individuals refusing to undergo testing (...) or declining participation in genomic research, and being asked to pay higher premiums or denied access to certain types of insurance. Obtaining informed consent for genetic testing and genomic research is crucial and should take into account the potential need to disclose possible insurability risks to patients and participants. Our study analyzed clinical and research consent forms, templates and guidelines from Quebec to investigate two questions: whether consent forms include clauses providing information on potential insurability risks and when such potential risks are included, what information is provided and how it is formulated. Our findings show that current information on insurability risks in Quebec’s forms/guidelines lack coherence, potentially resulting in patients/participants receiving inconsistent information.
