This study presents the fundamental concepts and technical details of a U-model-based control system design framework, including U-model realisation from classic model sets, control system design procedures, and simulated showcase examples. Consequently, the framework provides readers with clear understandings and practical skills for further research expansion and applications. In contrast to the classic model-based design and model-free design methodologies, this model-independent design takes two parallel formations: it designs an invariant virtual controller with a specified closed-loop transfer function in a feedback (...) control loop and it determines the real controller output by resolving the inverse of the plant U-model. It should be noted that this U-control provides a universal control system design platform for many existing linear/nonlinear and polynomial/state-space models and it complements many existing design approaches. Simulation studies are used as examples to demonstrate the analytically developed formulations and guideline for potential applications. (shrink)

The purpose of this research is to formulate a theory of self-transformation based on Avicenna’s psychology. The research method used is descriptive qualitative analysis. Self-transformation is the process of changing the soul quality as to produce better changes in perception and behavior. The background of the research includes the weaknesses of the existing self-transformation methods; Avicenna’s psychology directs the soul to perfect the transformation; Avicenna’s psychology does not discuss his self-transformation theory explicitly; Avicenna has a better formulation of self-transformation theory (...) than Aristotle implicitly; and it provides alternative self-transformation method.

The fault ride-through capability and fault current issues are the main challenges in doubly fed induction generator- based wind turbines. Application of the bridge-type fault current limiter was recognized as a promising solution to cope with these challenges. This paper proposes a nonlinear sliding mode controller for the BFCL to enhance the FRT performance of the DFIG-based WT. This controller has robust performance in unpredicted voltage sag level and nonlinear features. Theoretical discussions, power circuit, and nonlinear control consideration of the (...) SMC-based BFCL are conducted, and then, its performance is verified through time-domain simulations in the PSCAD/EMTDC environment. To reduce the chattering phenomenon and decrease the reaching time, it used the exponential reaching law for designed SMC. Also, the SMC-based BFCL performance is compared with the conventional and PI controller-based BFCL for both symmetrical and asymmetrical short-circuit faults. Simulation results reveal that the SMC-based BFCL provides better performance compared with the conventional and PI controller-based BFCL to enhance the FRT. (shrink)

Summary Background The principle of maximization, which roughly means that we should save more lives and more years of life, is usually taken for granted by the health community. This principle is even more forceful in crises like the COVID-19 pandemic, where we have scarce resources which can be allocated only to some patients. However, the standard consequentialist version of this principle can be challenging particularly when we have to reallocate a resource that has already been given to a patient. (...) -/- Methodology Engaging in thought experiments, conceptual analysis, providing counterexamples, and appealing to moral intuitions, we challenge the standard consequentialist version of the maximization principle and make a case for adopting an alternative deontological version. -/- Discussion In certain cases, the standard consequentialist version of the maximization principle is shown to yield intuitively immoral results. The deontological version of this principle is preferable because it can retain the merits of the standard consequentialist version without falling prey to its problems. -/- Conclusion Compared to the standard consequentialist version, the deontological version of the maximization principle can better guide the ethical decisions of the health community, even in cases where we face a scarcity of resources.

Teachers of science-based education in Malaysian secondary schools, especially those in the field of physics, often find their students facing huge difficulties in dealing with conceptual ideas in physics, resulting thus in a lack of interest towards the subject. The aim of this study was to assess the effectiveness of the Brain-Based Teaching Approach (henceforth BBTA) in dealing with the issues of the conceptual understanding of Newtonian physics of Form Four students in secondary science schools in the state of Kedah, (...) situated in the northern region of Peninsular Malaysia, and also their learning motivation towards the subject of physics. The BBTA is based on the Brain-Based Learning Principles, where detailed attention is given to seven main steps: (1) activation; (2) clarify the outcome and paint big picture of the lesson; (3) making connection; (4) doing the learning activity; (5) demonstrate student understanding; (6) review for student recall and retention/closure; and (7) preview the new topic. The effectiveness of the BBTA within the targeted context was then assessed in a quasi-experimental research approach involving 100 Form Four students from two secondary science schools. Data collected using the Test of Conceptual Understanding of Newtonian Physics and the Questionnaire of Physics Learning Motivation were then analysed descriptively and inferentially. The results obtained revealed that the BBTA was in fact exceedingly effective in dealing with the problems aforementioned. It was found that students who received physics education taught using the BBTA possessed a better conceptual understanding of Newtonian physics and also a higher learning motivation in the subject of physics, compared to students who received physics education taught using conventional teaching methods.

English summary: What is color? Are colors real properties of the world around us, or are they the secondary effects on our senses by the objects around us. Christophe Al-Saleh explores this contemporary philosophical debate over colors, objectivism, and subjectivism. French description: Il existe un ecart entre la conception familiere et commune des couleurs et la conception scientifique, la premiere y voyant spontanement des proprietes reelles du monde qui nous entoure, la seconde mettant en doute cette realite: les couleurs (...) ne seraient jamais que des effets secondaires consecutifs a l'affection de notre sensibilite par les objets qui nous entourent. C'est dans ce contexte que s'inscrit le debat philosophique contemporain sur les couleurs, entre l'objectivisme (les couleurs sont des proprietes presentes dans le monde) et le subjectivisme (les couleurs sont des productions subjectives).

According to the World Health Organization, female genital cutting affects millions of girls and women worldwide, particularly on the African continent and in the Middle East. This paper presents a plausible, albeit hypothetical, clinical vignette and then explores the legal landscape as well as the ethical landscape physicians should use to evaluate the adult patient who requests re-infibulation. The principles of non-maleficence, beneficence, justice, and autonomy are considered for guidance, and physician conscientious objection to this procedure is discussed as well. (...) Analyses of law and predominant principles of bioethics fail to yield a clear answer regarding performing female genital cutting or re-infibulation on an adult in the United States. Physicians should consider the patient’s physical, mental, and social health when thinking about female genital cutting and should understand the deep-rooted cultural significance of the practice.

The primary objective of this research is to examine the potential influence of environmental, social, and governance (ESG) disclosure on cash holdings. Additionally, the study explores the role of earnings management (EM) practices as a mediating factor in this relationship. The sample comprises 797 companies listed on financial markets across 19 European countries, and the data spans from 2013 to 2019. The outcomes indicate a significant negative correlation between ESG disclosure and cash holdings, implying that ESG performance can be used (...) by management to resolve disputes with stakeholders. The outcomes further indicate that the existence of EM practices partially mediates the link between ESG disclosure and cash holdings. Moreover, they are robust by substitute cash holdings specification, three distinct initiatives of ESG disclosure (i.e., environment, social, and governance), and a two-stage least squares assessment. Therefore, the findings document that nonfinancial reporting in the form of ESG disclosure can assist in controlling agency conflict, leading to better valuations of company performance by stakeholders.

It is hypothesized that iron from biological tissues, liberated during decay, may have played a role in inhibiting loss of anatomical information during fossilization of extinct organisms. Most tissues in the animal kingdom contain iron in different forms. A widely distributed iron‐bearing molecule is ferritin, a globular protein that contains iron crystallites in the form of ferrihydrite minerals. Iron concentrations in ferritin are high and ferrihydrites are extremely reactive. When ancient animals are decaying on the sea floor under anoxic environmental (...) conditions, ferrihydrites may initialize the selective replication of some tissues in pyrite FeS2. This model explains why some labile tissues are preserved, while other more resistant structures decay and are absent in many fossils. A major implication of this hypothesis is that structures described as brains in Cambrian arthropods are not fossilization artifacts, but are instead a source of information on anatomical evolution at the dawn of complex animal life.

In a friendly interdisciplinary debate, we interrogate from several vantage points the question of “personhood” in light of contemporary and near-future forms of social AI. David J. Gunkel approaches the matter from a philosophical and legal standpoint, while Jordan Wales offers reflections theological and psychological. Attending to metaphysical, moral, social, and legal understandings of personhood, we ask about the position of apparently personal artificial intelligences in our society and individual lives. Re-examining the “person” and questioning prominent construals of that category, (...) we hope to open new views upon urgent and much-discussed questions that, quite soon, may confront us in our daily lives.

Available from UMI in association with The British Library. Requires signed TDF. ;Two elements in Kripke's notion of "rigid designation" are distinguished: "genuine reference", which has to do with the semantic function of a singular term, and "rigid designation", which has to do with the behaviour of a singular term in modal contexts. Accordingly, the discussion is divided into two parts. ;In Part I, arguments from functionalism against "genuine reference" are considered and rejected, but it is claimed that certain Cartesian (...) arguments constitute a formidable objection against this notion. Therefore, while descriptivism must be rejected "genuine reference" is too strong as an alternative. "Weak reference" is suggested as the required notion, and some of its characteristics are delineated. ;In Part II, the problems concerning the contingent a priori and the necessary a posteriori arising from the second element in Kripke's notion are discussed, depending on whether the names involved are ordinary proper names, or "descriptive" names. Evans' arguments concerning descriptive names are considered, and it is argued that, because of a new distinction between deep vs. superficial rigidity, Davies and Humberstone fail in formulating them more exactly; but the informal arguments, though inconclusive, are intuitive. As for ordinary proper names, and on the basis of conclusions reached in Part I, the case for contingent a priori truths involving such names is undermined. In the case of necessary a posteriori truths involving ordinary proper names, the strategies of denying the necessity or the a posteriority of the examples are discussed, and found wanting. However, since there are reasons from other areas for denying the coincidence of the necessary and the a priori, Kripke's examples do not call for a radical departure from currently held views.

Argumentation has remained under-researched in studies analyzing academic journal publications despite its importance in academic writing. This paper reports a study in which we investigated stereotypical argumentative trends, lexico-grammatical features, and interactional metadiscourse markers in 354 research article free-standing discussion sections from the journal of ESP over forty years. The field of ESP was chosen because of its maturity, which has given substance to a dynamic ground for arguments. We drew on the pragma-dialectical approach to analyzing argumentations in the corpus. (...) Findings indicated that due to the argumentative nature of the discussion section, certain argumentative trends recurred more often. The analysis of the lexico-grammatical features and metadiscourse markers of the standpoints also showed patterns of variability over time. The study concludes that it is imperative to incorporate relevant facets from various argumentation models to construct a comprehensive argumentation theory and gain deeper insights into argumentation in academic writing.

What is it for an agent to have a reason to do a certain action? Does this mean that she would desire to do the action under specified conditions, or that there is some external consideration, which she ought to follow? The former affective (i.e., desire-based) theory is ascribed to Humeans, whereas the latter cognitive theory is adopted by Kantians. The debate between the two views has seemingly ended up in a theoretical standoff, and most of the theorists of practical (...) reason have recently turned their attention to the motivational attitude—preceded either by affective attitudes or by cognitive attitudes—as a necessary constituent of having a reason. They contend that an agent has a reason to f only if, on certain occasions, she would be motivated to f: I refer to it as Motivation Reason Internalism. In this paper, I argue that Motivation Reason Internalism is a mirage; it does not obtain necessarily. I classify major versions of Motivation Reason Internalism into three idealized counterfactual versions, arguing that they obtain only contingently, since they all face counterexamples. The Motivation Reason Internalist might attempt to dodge the counterexamples by appealing to Contextual Motivations Reason Internalism, but I show that this move also fails. I discuss a third cause for motivation, some unconscious cause, other than cognitive or affective attitudes, which can still be a motivation maker or breaker. These unconscious causes, such as an underlying biological inclination or psychological bias, functions as motivation maker/breaker but not a reason maker/breaker. This makes room for a variety of cases in which we have reason to perform an action in the absence of any kind (i.e., actual or counterfactual) of motivation. (shrink)

Gregory the Great depicts himself as a contemplative who, as bishop of Rome, was compelled to become an administrator and pastor. His theological response to this existential tension illuminates the vexed questions of his relationships to predecessors and of his legacy. Gregory develops Augustine’s thought in such a way as to satisfy John Cassian’s position that contemplative vision is grounded in the soul’s likeness to the unity of Father and Son. For Augustine, “mercy” lovingly lifts the neighbor toward life in (...) God. Imitating God’s own love for humankind, this mercy likens the Christian to God’s essential goodness and, by this likeness, prepares him or her for the vision of God, which Augustine expects not now but only in the next life. For Augustine, the exercise of mercy can—when useful—involve a shared affection or understanding. Gregory makes this shared affection essential to the neighborly love that he calls “compassion.” In this affective fellowship, Gregory finds a human translation of the passionless unity of Father and Son—so that, for Gregory, compassion becomes the immediate basis for and consequence of seeing God—even in this life. Compassion does not degrade; rather, it retrenches the perfection of contemplation. Reconciling compassionate activity and contemplative vision, this creative renegotiation of Augustine and Cassian both answered Gregory’s own aspirations and gave to the tumultuous post-Imperial West a needed account of worldly affairs as spiritual affairs.

BackgroundClinical genomic professionals are increasingly facing decisions about returning incidental findings (IFs) from genetic research. Although previous studies have shown that research participants are interested in receiving IFs, yet there has been an argument about the extent of researcher obligation to return IFs. We aimed in this study to explore the perspectives of clinical genomics professionals toward returning incidental findings from genomic research.MethodsWe conducted a national survey of a sample (n = 113) of clinical genomic professionals using a convenient sampling. (...) A self-administered questionnaire was used to explore their attitudes toward disclosure of IFs, their perception of the duties to return IFs and identifying the barriers for disclosure of IFs. A descriptive analysis was employed to describe participants' responses.ResultsSixty-five (57.5%) respondents had faced IFs in their practice and 31 (27.4%) were not comfortable in discussing IFs with their research subjects. Less than one-third of the respondents reported the availability of guidelines governing IFs. The majority 84 (80%) and 69 (62.7%) of the study participants indicated they would return the IFs if the risk of disease threat ≥ 50% and 6–49%, respectively and 36 (31.9%) reported they have no obligation to return IFs.ConclusionClinical genomics professionals have positive attitudes and perceptions toward the returning IFs from genomic research, yet some revealed no duty to do so. Detailed guidelines must be established to provide insights into how genomics professionals should be handled IFs. (shrink)

This article addresses the issue of professionalization in the life sciences during the second half of the nineteenth century through a survey of British entomological periodicals. It is generally accepted that this period saw the rise of professional practitioners and the emergence of biology (as opposed to the older mode of natural history). However, recent scholarship has increasingly shown that this narrative elides the more complex processes at work in shaping scientific communities from the 1850s to the turn of the (...) century. This article adds to such scholarship by examining the ways in which the editors of four entomological periodicals from across this time frame attempted to shape the communities of their readership, and in particular focuses upon the apparent divide between ‘mere collectors’ and ‘entomologists’ as expressed within these journals. Crucially, the article argues that non-professional practitioners were active in defining their own distinct identities and thereby claiming scientific authority. Alongside the periodicals, the article makes use of the correspondence archive of the entomologist and periodical editor Henry Tibbats Stainton (1822–1892), which has hitherto not been subject to sustained analysis by historians.

Communicative practices in online and social media sometimes seem to amplify political conflict, and result in significant harms to people who become the targets of collective outrage. Many complaints that have been made about political correctness in the past, we argue, amount to little more than a veiled expression of resentment over the increasing influence enjoyed by progressive activists. But some complaints about political correctness take on a different complexion, in light of the technologically-driven changes to our communicative practices and (...) political discourse. Given the ways in which they are entangled in these new forms of online communication, well-meaning attempts to police the norms of political correctness may end up contributing to individual wrongs, or to destructive social patterns. In this paper we examine these worries, situate them in a broader sociological context, and offer some tentative proposals about how they might be addressed. (shrink)

There is a growing interest in non-invasive stimulation interventions as treatment strategies to improve functional outcomes and recovery after spinal cord injury. Repetitive transcranial magnetic stimulation is a neuromodulatory intervention which has the potential to reinforce the residual spinal and supraspinal pathways and induce plasticity. Recent reviews have highlighted the therapeutic potential and the beneficial effects of rTMS on motor function, spasticity, and corticospinal excitability modulation in SCI individuals. For this scoping review, we focus on the stimulation parameters used in (...) 20 rTMS protocols. We extracted the rTMS parameters from 16 published rTMS studies involving SCI individuals and were able to infer preliminary associations between specific parameters and the effects observed. Future investigations will need to consider timing, intervention duration and dosage that may depend on the stage, the level, and the severity of the injury. There is a need for more real vs. sham rTMS studies, reporting similar designs with sufficient information for replication, to achieve a significant level of evidence regarding the use of rTMS in SCI.

In this article, I explore a possible ‘conversation’ between a leading African political sociologist, Peter P. Ekeh, in his theory of ‘two publics’, and the late French philosopher, historian and social theorist, Michel Foucault, in his theory of governmentality. I examine the ‘lingering effects of colonialism’ and point to how Ekeh’s insight and its usefulness for examining the politico-cultural consequences of colonialism in terms of the conduct of conduct in the public realm can be further enriched by relating it to (...) the deeply penetrating insight on the nature of power and domination articulated through the concept of governmentality and sovereign power. The paper concludes that Ekeh’s thesis is particularly suitable for interrogating governmentality and its useful insights for understanding public life in Africa because, like Foucault’s theory of governmentality, it is grounded on a historical account of contemporary processes of socio-political and economic configuration.

"Publié en 1994, traduit chez Vrin en 2007, L'esprit et le monde de John McDowell n'a cessé de susciter des débats dans le monde philosophique anglo-saxon, sur l'esprit, la connaissance, le langage et la nature, contribuant à définir de nouvelles questions. Pour la première fois, cette oeuvre, qui emprunte aussi bien à Wittgenstein, Strawson et Davidson qu'à Kant et Hegel, et tente de dépasser l'opposition traditionnelle entre la philosophie dite "continentale" et la philosophie dite "analytique", fait l'objet d'une lecture critique (...) en France. Les contributions ici rassemblées, ainsi que les réponses de John McDowell, font suite à une "première vague" de commentaires critiques qui lui furent adressés et qui le conduisirent à s'expliquer sur ses thèses et à en modifier légèrement quelques-unes (comme la thèse du contenu conceptuel de la perception). On trouvera ici, dans les différentes contributions, un éclairage sur les raisons et les portées de cette critique, et, dans les réponses, des formulations pour la plupart tout à fait inédites de McDowell."--Page 4 de la couverture.

In MacIntyre’s view, the agent in order to have a consistent identity should be able to narrate a story about her life, which relates the different episodes of her life together. This story should explain the transition between these episodes. This story is based on the notion of the good of human beings. A notion of the good should be present in the agent’s life to give a direction to her life. This integrity forms an identity for the agent. We (...) intend to challenge this narrative view of identity in this paper. We will argue in this paper that though identity is formed in the eye of others, it does not need to be constituted in a unified narrative form, i.e., the agent does not need to place all episodes of her life in narrative order and have a consistent and unified account of her life, which includes her life from birth to death. Rather, shorter-term episodes of time suffice for identity formation. We will appeal to some findings of empirical psychology and neuroscience to support our claim. (shrink)

Twitter is a virtual social network where people share their posts and opinions about the current situation, such as the coronavirus pandemic. It is considered the most significant streaming data source for machine learning research in terms of analysis, prediction, knowledge extraction, and opinions. Sentiment analysis is a text analysis method that has gained further significance due to social networks’ emergence. Therefore, this paper introduces a real-time system for sentiment prediction on Twitter streaming data for tweets about the coronavirus pandemic. (...) The proposed system aims to find the optimal machine learning model that obtains the best performance for coronavirus sentiment analysis prediction and then uses it in real-time. The proposed system has been developed into two components: developing an offline sentiment analysis and modeling an online prediction pipeline. The system has two components: the offline and the online components. For the offline component of the system, the historical tweets’ dataset was collected in duration 23/01/2020 and 01/06/2020 and filtered by #COVID-19 and #Coronavirus hashtags. Two feature extraction methods of textual data analysis were used, n-gram and TF-ID, to extract the dataset’s essential features, collected using coronavirus hashtags. Then, five regular machine learning algorithms were performed and compared: decision tree, logistic regression, k-nearest neighbors, random forest, and support vector machine to select the best model for the online prediction component. The online prediction pipeline was developed using Twitter Streaming API, Apache Kafka, and Apache Spark. The experimental results indicate that the RF model using the unigram feature extraction method has achieved the best performance, and it is used for sentiment prediction on Twitter streaming data for coronavirus.

RésuméSelon Avicenne, certains objets des mathématiques existent et d'autres non. Chaque objet mathématique existant est un attribut connotationnel non sensible d'un objet physique et peut être perçu par la faculté d'estimation. Les objets mathématiques non existants peuvent être représentés et perçus par la faculté d'imagination en séparant et en combinant des parties d'images d'objets mathématiques existants qui sont précédemment perçues par estimation. Dans tous les cas, même les objets mathématiques non existants doivent être considérés comme des propriétés d'entités matérielles. Ils (...) ne peuvent jamais être saisis comme des entités totalement immatérielles. Avicenne pense que nous ne pouvons saisir aucun concept mathématique à moins d'avoir au préalable des expériences perceptives spécifiques. Ce n'est que par l'opération non éliminable et irremplaçable des facultés d'estimation et d'imagination sur certaines données sensibles que nous pouvons saisir les concepts mathématiques. Cela montre qu'Avicenne approuve une sorte d'empirisme conceptuel sur les mathématiques. (shrink)
