The human masticatory system is a complex functional unit characterized by a multitude of skeletal components, muscles, soft tissues, and teeth. Muscle activation dynamics cannot be directly measured on live human subjects due to ethical, safety, and accessibility limitations. Therefore, estimation of muscle activations and their resultant forces is a longstanding and active area of research. Reinforcement learning (RL) is an adaptive learning strategy which is inspired by the behavioral psychology and enables an agent to learn the dynamics of an (...) unknown system via policy-driven explorations. The RL framework is a well-formulated closed-loop system where high capacity neural networks are trained with the feedback mechanism of rewards to learn relatively complex actuation patterns. In this work, we are building on a deep RL algorithm, known as the Soft Actor-Critic, to learn the inverse dynamics of a simulated masticatory system, i.e., learn the activation patterns that drive the jaw to its desired location. The outcome of the proposed training procedure is a parametric neural model which acts as the brain of the biomechanical system. We demonstrate the model’s ability to navigate the feasible three-dimensional (3D) envelope of motion with sub-millimeter accuracies. We also introduce a performance analysis platform consisting of a set of quantitative metrics to assess the functionalities of a given simulated masticatory system. This platform assesses the range of motion, metabolic efficiency, the agility of motion, the symmetry of activations, and the accuracy of reaching the desired target positions. We demonstrate how the model learns more metabolically efficient policies by integrating a force regularization term in the RL reward. We also demonstrate the inverse correlation between the metabolic efficiency of the models and their agility and range of motion. The presented masticatory model and the proposed RL training mechanism are valuable tools for the analysis of mastication and other biomechanical systems. We see this framework’s potential in facilitating the functional analyses aspects of surgical treatment planning and predicting the rehabilitation performance in post-operative subjects. (shrink)

It is obvious that the use of these various terms does not result in a miscellany of ideas such as it occurs in many New Age theories. In perennialists’ writings we have come to realize that this is not an attempt to mix traditions together, but is instead an attempt to utilize existing terminology when it is appropriate. The paper has focused at studying the anthropology of perfection in perennial philosophy. It has addressed issues such as the nature of ‘self (...) and the states of self-realization’, selfessness and selfi shness’, ‘the categories of man’, ‘the process of exaltation’, ‘attributes’, ‘qualities’, ‘rights and obligations of the superior man in traditional worldview. In various places of the paper we have resorted to artworks belonging to various traditions and different times to communicate the ideas and worldviews. They show how essential the role of artists and the art they produce is in keeping alive the reverence for perfection and continuity of tradition through their inspired imagination. The superior qualities are not necessarily those of rulers and conquerors. They are rather to be found in mythical heroes, prophets of God and sages of various traditions; those who, in Ghazali’s words, “possess inner vision”. Such individuals hold attributes of perfection; their bodies die, yet their characters live beyond time and space inspiring generations after generations. After all, to be a superior being means starting a never-ending journey of becoming. (shrink)

The present study investigates the collocation-induced semiosis of the linguistic sign AFRICA as being used in the academic section of the Corpus of Contemporary American English (known as COCA) (Davies, Mark. 2008. The Corpus of Contemporary American English (COCA): one billion words, 1990-present. Available online at https://corpus.byu.edu/coca/). Drawing on a hybrid theoretical framework, the study utilizes Charles Peirce’s (1931–58) semiotic model of the sign and Roman Jakobson’s theory of “markedness” (Jakobson, Roman. 1972. Verbal communication. Scientific American (Special Issue, September 1). (...) 73–80) as well as Stuart Hall’s treatment of “code” (Hall, Stuart. 1980. Encoding/decoding. In Stuart Hall, Doothy Hobson, Andrew Lowe, & Paul Willis (eds.), Culture, media, language: Working papers in cultural studies, 1972–79, 117–127. New York: Routledge) and John Swales’ notion of “discourse community” (Swales, John M. 1990. Genre analysis: English in academic and research settings. Cambridge: Cambridge University Press). The study empirically tests the hypothesis that, in a given discourse domain, the relevant interpretant can decode a linguistic sign (representamen) in the co-text of its marked collocates in a way that is collocationally used via the two modes of iconic and indexical signification. The concordance-based analysis conducted in the present study offers two findings, theoretical and practical. First, the study proposes the theoretical concept of collocational semiosis as one way of methodologically integrating the study of collocation into a structural-linguistic analytic framework that richly intersects with the genre-based notion of “discourse community.” Second, in the academic discourse community of the COCA, to the expert interpretant, the representamen AFRICA has been decoded due to its marked collocates which have been technically used in two modes of signification, viz. iconic and indexical.

The 25th of January, 2011 witnessed a wave of political unrest all over Egypt, with repercussions that have re-shaped the future of contemporary Egypt. For the first time in the modern history of Egypt since the 1952 Nasserite revolution, grass-root protestors went to streets chanting slogans against the military regime headed by the (since then ex-) President of Egypt, Hosni Mubarak. This placed the then regime, as well as its mainstay, the National Democratic Party (NDP), in a political crisis on (...) both local and international scales. It is this critical moment that led Mubarak to give his unprecedented speech on February 1st, 2011. The speech has brought about epoch-making political changes in the history of contemporary Egypt. Under public pressure, two seminal declarations were made in this speech: (1) Mubarak’s intention not to nominate himself for a new presidential term; (2) a call on the Houses of Parliament to amend articles 76 and 77 of the constitution concerning the conditions on running for presidency and the period for the presidential term in Egypt. The present paper seeks to answer the following overarching question: what are the discursive strategies used for saving the political face of Mubarak in his speech on February 1st, 2011? I follow a text-analytic framework based on the socio-semantic theory of social actors and the pragmatic models of speech acts and face-threatening acts. The analysis reveals Mubarak’s attempt to save his positive political face as a legitimate President who regarded himself as the official ruler invested with absolute power over Egypt. (shrink)

One of the central topics in semantic theory over the last few decades concerns the nature of local contexts. Recently, theorists have tried to develop general, non-stipulative accounts of local contexts (Schlenker, 2009; Ingason, 2016; Mandelkern & Romoli, 2017a). In this paper, we contribute to this literature by drawing attention to the local contexts of subclausal expressions. More specifically, we focus on the local contexts of quantificational determiners, e.g. `all', `both', etc. Our central tool for probing the local contexts of (...) subclausal elements is the principle Maximize Presupposition! (Percus, 2006; Singh, 2011). The empirical basis of our investigation concerns some data discussed by Anvari (2018b), e.g. the fact that sentences such as `All of the two presidential candidates are crooked' are unacceptable. In order to explain this, we suggest that the local context of determiners needs to contain the information carried by their restrictor. However, no existing non-stipulative account predicts this. Consequently, we think that the local contexts of subclausal expressions will likely have to be stipulated. This result has important consequences for debates in semantics and pragmatics, e.g. those around the so-called "explanatory problem" for dynamic semantics (Soames, 1982; Heim, 1990; Schlenker, 2009).

We proposed a model to examine the relationship among different types of weight-related stigmas and their relationship to quality of life. We recruited 430 dyads of elementary school children [mean age = 10.07 years; nboy = 241 ; noverweight = 138 ] and their parents. Parents completed QoL instruments about their children assessing generic QoL and weight-related QoL. Children completed QoL instruments assessing generic QoL and weight-related QoL and stigma scales assessing experienced weight stigma, weight-related self-stigma, and perceived weight stigma. (...) Experienced weight stigma was significantly associated with perceived weight stigma, and in turn, perceived weight stigma was significantly associated with weight-related self-stigma. However, experienced weight stigma was not directly associated with weight-related self-stigma. In addition, experienced stigma was negatively associated with both child-rated and parent-rated QoL. Perceived weight stigma was associated only with parent-rated weight-related QoL but not child-rated QoL. Self-stigma was associated with child-rated QoL but not parent-rated QoL. Moreover, perceived weight stigma and weight-related self-stigma were significant mediators in the association between body weight and children's QoL; experienced weight stigma was not a significant mediator. The study findings can be used to inform healthcare providers about the relationship among different types of stigmas and their influence on child-rated and parent-rated QoL and help them develop interventions to address the global trend of overweight/obesity in youth and pediatric populations.

Brain activity in the action observation network is lateralized during action execution, with greater activation in the contralateral hemisphere to the side of the body used to perform the task. However, it is unknown whether the AON is also lateralized when watching another person perform an action. In this study, we use fNIRS to measure brain activity over the left and right cortex while participants completed actions with their left and right hands and watched an actor complete action with their (...) left and right hands. We show that while activation is lateralized when the participants themselves are moving, brain lateralization is not affected by the side of the body when the participant is observing another person’s action. In addition, we demonstrate that individual differences in hand preference and dexterity between the right and left hands are related to brain lateralization patterns. (shrink)

Background Moral distress is a common challenge among professional nurses when caring for their patients, especially when they need to make rapid decisions. Therefore, leaving moral distress unconsidered may jeopardize patient quality of care, safety, and satisfaction. Aim To estimate moral distress among nurses. Methods This systematic review and meta-analysis conducted systematic search in Scopus, PubMed, ProQuest, ISI Web of Knowledge, and PsycInfo up to end of February 2022. Methodological quality of included studies was assessed using the Newcastle Ottawa checklist. (...) Data from included studies were pooled by meta-analysis with random effect model in STATA software version 14. The selected key measure was mean score of moral distress total score with its’ 95% Confidence Interval was reported. Subgroup analyses and meta-regressions were conducted to identify possible sources of heterogeneity and potentially influencing variables on moral distress. Funnel plots and Begg’s Tests were used to assess publication bias. The Jackknife method was used for sensitivity analysis. Ethical consideration The protocol of this project was registered in the PROSPERO database under decree code of CRD42021267773. Results Eighty-six manuscripts with 19,537 participants from 21 countries were included. The pooled estimated mean score of moral distress was 2.55 on a 0–10 scale [95% Confidence Interval: 2.27–2.84, I2: 98.4%, Tau2:0.94]. Publication bias and small study effect was ruled out. Moral distress significantly decreased in the COVID-19 pandemic versus before. Nurses working in developing countries experienced higher level of moral distress compared to their counterparts in developed countries. Nurses' workplace (e.g., hospital ward) was not linked to severity of moral disturbance. Conclusion The results of the study showed a low level of pooled estimated score for moral distress. Although the score of moral distress was not high, nurses working in developing countries reported higher levels of moral distress than those working in developed countries. Therefore, it is necessary that future studies focus on creating a supportive environment in hospitals and medical centers for nurses to reduce moral distress and improve healthcare. (shrink)

Over recent years, the research community has been increasingly using preprint servers to share manuscripts that are not yet peer-reviewed. Even if it enables quick dissemination of research findings, this practice raises several challenges in publication ethics and integrity. In particular, preprints have become an important source of information for stakeholders interested in COVID19 research developments, including traditional media, social media, and policy makers. Despite caveats about their nature, many users can still confuse pre-prints with peer-reviewed manuscripts. If unconfirmed but (...) already widely shared first-draft results later prove wrong or misinterpreted, it can be very difficult to “unlearn” what we thought was true. Complexity further increases if unconfirmed findings have been used to inform guidelines. To help achieve a balance between early access to research findings and its negative consequences, we formulated five recommendations: (a) consensus should be sought on a term clearer than ‘pre-print’, such as ‘Unrefereed manuscript’, “Manuscript awaiting peer review” or ‘’Non-reviewed manuscript”; (b) Caveats about unrefereed manuscripts should be prominent on their first page, and each page should include a red watermark stating ‘Caution—Not Peer Reviewed’; (c) pre-print authors should certify that their manuscript will be submitted to a peer-review journal, and should regularly update the manuscript status; (d) high level consultations should be convened, to formulate clear principles and policies for the publication and dissemination of non-peer reviewed research results; (e) in the longer term, an international initiative to certify servers that comply with good practices could be envisaged.

The human being is the most wonderful creation of God and the highest sign of his infinite power. Humanity is capable of achieving all divine perfections. God created them to reach the position of God’s closeness and God’s successor on Earth, and this path will not be realised except by the correct education. A human is a divine being who has settled in this earthly world, and correct education is the only way to achieve that sacred truth. Divine prophets have (...) come to prepare the Earth for this great transformation in human existence and guide them to the light of divine teachings. There is no doubt that if human beings are not educated according to divine standards, they will remain at the level of animality. The Holy Qur’an, as the most precious Islamic divine book, presents the best way of education based on the knowledge of the truth of humanity and their needs. In addition, it is appropriate to discuss the role of behavioural gentleness in the education of people, and in this regard, the Qur’anic verses have been reviewed carefully. Therefore, the aim of this manuscript is to study the Islamic teachings in education with an emphasis on behavioural gentleness.Contribution: If curriculum planners and educators in general pay attention to Qur’anic teachings in education and base their curriculum and educational programs on Qur’anic teachings and according to characteristics and abilities and appropriateness of methods, and if the contents are paid attention to and educational programs are produced based on the will and authority of the educators, we will definitely witness progress and development in educational systems on the one hand and development and progress in all levels of life.

Religious diversity is a key topic in contemporary philosophy of religion. One way religious diversity has been of interest to philosophers is in the epistemological questions it gives rise to. In other words, religious diversity has been seen to pose a challenge for religious belief. In this study four approaches to dealing with this challenge are discussed. These approaches correspond to four well-known philosophers of religion, namely, Richard Swinburne, Alvin Plantinga, William Alston, and John Hick. The study is concluded by (...) suggesting four factors which shape one’s response to the challenge religious diversity poses to religious belief. (shrink)

Government is a rational necessity for mankind because a society without government leads to chaos. Government regulates the affairs of the individual and the community, implements the limits, and ensures the dignity and independence of the human society. Thinking in the main goals of the divine prophets, it is clear that achieving great goals such as liberating people from the domination and captivity of foreigners, comprehensive human education, reviving human values, establishing justice, bringing people to excellence and growth, etc., requires (...) formation. In this context, transparency is a key attribute, which can bring much power to the expected level as an effective mechanism for protecting citizens’ political, economic, social and cultural rights. This concept is thus a valuable solution in the fight against sinister phenomena, such as political and economic corruptions, which are ranked as the biggest challenges facing any society. Even though transparency is nowadays deemed an emerging concept, its roots can be traced back to Islamic teachings, mainly during the short reign of Imam Ali, (peace be upon him [PBUH]). As a central figure, Imam Ali considered transparency as essential, and shared his views on governance and practical methods with the people and all audiences based on complete honesty and openness. As per Alavi thoughts, some criteria and indicators, both structural and behavioural, are involved in order to ensure the public good and meet the interests of all by providing the prerequisites for the realisation of transparency, at odds with the predominant ideas that transparency in governance, like many concepts in the political and governance-related spheres, has a western origin. Contribution: The concept of transparency, with a proven history in global experiences, accordingly holds a special place in the literature of Islamic governments. Given the importance of this topic, the present study with an emphasis on transparency aims to examine Islamic teachings on governance in Islamic societies, and reflect on governance transparency components in such societies, relying on expert opinions.

The present essay explores the question of continuity and change between Kaneš and Ḫattuša in the cultic sphere, reviewing the cult of Parga, probably a fertility goddess of local Anatolian origin, in the Hittite sources. It reveals that Parga appears in several different cultic contexts but within a relatively invariable sequence of offerings, often appearing with the same, often “exotic” deities, such as Zūluma, Šišumma/i, and Šurra. The probable location for performance of many of these cultic sequences in the lower (...) town of Ḫattuša, one of the most ancient parts of the city, shows a great deal of continuity between the Old Assyrian and the Old Hittite periods, and may further highlight the antiquity of these cults. Since some of the cultic action considered in this essay took place in close proximity to the ašuša-gate, the evidence concerning the location of that gate, probably at the western or northwestern section of the fortification wall and near some of the institutions located in its vicinity, will be examined.

In this paper we prove the equiconsistency of "Every ω 1 -tree which is first order definable over (H ω 1 ·ε) has a cofinal branch" with the existence of a Π 1 1 reflecting cardinal. We also prove that the addition of MA to the definable tree property increases the consistency strength to that of a weakly compact cardinal. Finally we comment on the generalization to higher cardinals.

To sum up, then, both kinds of Putnam's arguments established externalism, though they suffer from several defects. Yet, I think Searle's discussion of these arguments contributes to our understanding of what makes externalism true, and forces us to accept a moderate version of externalism. Searle's own account of the TE story shows us, within a solipsistic outline, how two identical mental states can be directed towards different objects, and further, that the content-determination of indexical thoughts does not necessarily involve external (...) factors. We are thus led to search elsewhere (i.e., not in the nature of indexical thoughts nor in the mere fact of there being identical thoughts with different intentionalities) for what makes the thoughts in question ‘external’. Searle formulates the thesis that intension determines extension as asserting that intension sets certain conditions that anything has to meet in order to fall under its extension. I showed that this is a trivial and implausible understanding of that thesis. Yet, it leads us to distinguish between an intension's setting conditions for falling under its extension and its fully determining such conditions, and thus to see in what sense externalism is true: in the sense that there are intensions that do not fully determine the conditions for falling under their extensions. Rather, they leave indeterminacies. This version of externalism is a moderate one, since though the intensions do not fully determine extensions, they, so to speak, determine their indeterminacies, by specifying the possible external facts that can complete the determination of extension. (The intensions, as I said, function like open sentences, and can be viewed as narrow contents.) So what's in the head plays a much more important role in determining content than Putnam takes it to play. Searle's pointing out that Hilary's concepts ‘elm’ and ‘beech’ are different also contributes to seeing this phenomenon: we realize that in that case the difference between the concepts is what is responsible for the fact that the completions of the extension-determinations are different. I think that this way of viewing the facts shows that ‘the externalist turn’ is not a great revolution, and that with the help of the concept of narrow content we can accept it without abandoning the traditional views about the mind as the source of content, and without being embarrassed by the very idea of (realistic) belief-desire psychology.

Jewish culture and universal perspectives.

For a function $f$ with domain $[X]^{n}$, where $X\subseteq\mathbb{N}$, we say that $H\subseteq X$ is canonical for $f$ if there is a $\upsilon\subseteq n$ such that for any $x_{0},\ldots,x_{n-1}$ and $y_{0},\ldots,y_{n-1}$ in $H$, $f=f$ iff $x_{i}=y_{i}$ for all $i\in\upsilon$. The canonical Ramsey theorem is the statement that for any $n\in\mathbb{N}$, if $f:[\mathbb{N}]^{n}\rightarrow\mathbb{N}$, then there is an infinite $H\subseteq\mathbb{N}$ canonical for $f$. This paper is concerned with a model-theoretic study of a finite version of the canonical Ramsey theorem with a largeness (...) condition and also a version of the Kanamori–McAloon principle. As a consequence, we produce new indicators for cuts satisfying $\operatorname{PA}$. (shrink)

Sensory substitution devices (SSDs) are most familiar from their use with subjects who are deficient in a target modality (e.g. congenitally blind subjects), but there is no doubt that the use and potential value of SSDs extend to persons without such deficits. Recent work by Amedi and his team (in particular Levy-Tzedek et al. 2012) has begun to explore this. Their idea is that SSDs may facilitate behavioural transference (BT) across sense modalities. In this case, a motor skill learned through (...) visual perception might be subsequently employed in response to auditory perception, using an SSD as a mediator. They infer from the existence of such BT that the learned skill is amodally represented. After a brief overview I identify ways to more fully test for BT within this experimental paradigm and argue that their conclusion about amodal representation is premature. Additionally, I argue that their preferred SSD (Eyemusic) is of limited value for the project. While my remarks are critical, my intention is to be constructive, particularly in light of the fact that Levy-Tzedek et al. (2012), is, I believe, the first output from Amedi's lab concerning this line of research. (shrink)

Ẓuhūr al-amān (The advent of security) is a book on civics published during the reign of Ammanullah Khan (1919-29) as amir of Afghanistan. The book's title pays homage to the name of Ammanullah Khan himself. In its treatment of the duties of the members of Afghan society to the ruler and to each other, Ẓuhūr al-amān appears to highlight the challenges faced by Ammanullah Khan in his efforts to modernize Afghanistan. The book is divided into more than 30 short (...) chapters describing the rights and responsibilities of the ruler, of persons living within a family unit, and of members of Afghan society as a whole. Some sections, such as one on the rights that are to be afforded to the king (ḥuquq-i lazima bar padishah), are further divided into subsections. The book begins with several chapters on religious matters, including those on tauhid (the unity of God), on ʻibada (worship), and on fahm-i sharīʻat-i rasūl ʻalayhi al-salām (the sharia). Ẓuhūr al-amān was published on October 11, 1923, by the then newly established Ministry of Education. The author of the work, a religious scholar by the name of ʻAbd al-Haqq, lists his father as ʻAbd al-ʻAziz from the village of Lower Arghanda in the township of Paghman, near Kabul. He highlights, as well, his tribal affiliation with the well-known Pushtun tribe of Suleimankhel. (shrink)

This is the first complete, one-volume English translation of the ancient Chinese text Xunzi, one of the most extensive, sophisticated, and elegant works in the tradition of Confucian thought. Through essays, poetry, dialogues, and anecdotes, the Xunzi articulates a Confucian perspective on ethics, politics, warfare, language, psychology, human nature, ritual, and music, among other topics. Aimed at general readers and students of Chinese thought, Eric Hutton’s translation makes the full text of this important work more accessible in English than ever (...) before. Named for its purported author, the Xunzi has long been neglected compared to works such as the Analects of Confucius and the Mencius. Yet interest in the Xunzi has grown in recent decades, and the text presents a much more systematic vision of the Confucian ideal than the fragmented sayings of Confucius and Mencius. In one famous, explicit contrast to them, the Xunzi argues that human nature is bad. However, it also allows that people can become good through rituals and institutions established by earlier sages. Indeed, the main purpose of the Xunzi is to urge people to become as good as possible, both for their own sakes and for the sake of peace and order in the world. In this edition, key terms are consistently translated to aid understanding and line numbers are provided for easy reference. Other features include a concise introduction, a timeline of early Chinese history, a list of important names and terms, cross-references, brief explanatory notes, a bibliography, and an index.
