In the recent years, an alarming rise in the incidence of cyber attacks has made cyber security a major concern for nations across the globe. Given the current volatile socio-political environment and the massive increase in the incidence of terrorism, it is imperative that government agencies rapidly realize the possibility of cyber space exploitation by terrorist organizations and state players to disrupt the normal way of life. The threat level of cyber terrorism has never been as high as it is (...) today, and this has created a lot of insecurity and fear. This study has focused on different aspects of cyber attacks and explored the reasons behind their increasing popularity among the terrorist organizations and state players. This study proposes an empirical model that can be used to estimate the risk levels associated with different types of cyber attacks and thereby provide a road map to conceptualize and formulate highly effective counter measures and cyber security policies.

Recent studies from Western countries indicate significant levels of questionable research practices, but similar data from low and middle-income countries are limited. Our aims were to assess the prevalence of and attitudes regarding research misconduct among researchers in several universities in the Middle East and to identify factors that might account for our findings. We distributed an anonymous questionnaire to a convenience sample of investigators at several universities in Egypt, Lebanon, and Bahrain. Participants were asked to a) self-report their extent (...) of research misconducts, as well as their knowledge of colleagues engaging in similar research misconducts and b) provide their extent of agreement with certain attitudes about research misconduct. We used descriptive, bivariate, and multivariate logistic regression statistics to analyze the data. Data from 278 participants showed a high prevalence of misconduct, as 59.4% of our respondents self-reported to committing at least one misbehaviors and 74.5% reported having knowledge of any misbehaviors among any of their colleagues. The most common type of self-report misconduct was “circumventing research ethics regulations” followed by “fabrication and falsification”. A significant predictor of misconduct included a lack of “prior ethics training”. Scientific misconduct represents a significant issue in several universities in the Middle East. The demonstration that a lack of “prior ethics training” was a significant predictor of misconduct should lead to educational initiatives in research integrity. Further studies are needed to confirm whether our results can be generalized to other universities in the Middle East. (shrink)

Recruiting patients into clinical research is essential for the advancement of medical knowledge. However, when the physician undertaking the care of the patient is also responsible for recruitment into clinical research, a situation arises of an inter-role breach of confidentiality which is distinguishable from other conflicts of interest. Such discord arises as the physician utilizes confidential information obtained within the therapeutic relationship beyond its primary objective, and safeguards ought to be observed in order to avert this important, and generally overlooked, (...) problem. The moral worth of the pledge of confidentiality is based not on its innate value but on its being a promise on which subsequent interactions and disclosures are founded. Within the patient-doctor interaction, confidentiality is an important facet of the promised fidelity and, as such, a loose interpretation of the notion threatens the essence of the relationship, and any violation thereof requires compelling moral justification. To avoid conflict, patients' confidential information ought not be used for the purpose of recruitment, which needs to be undertaken through general education and non-directed appeals, and a preliminary consent to be approached for research should be obtained from the patient prior to her being identified as a suitable research subject. Securing this prior consent would avoid one source of potential, albeit unintended, coercion. (shrink)

The present study aims at explaining how the Relevance Theory could be a viable approach to weigh up the main functions of some concessive Pragmatic Operators in Jordanian Arabic at the production and interpretation levels. A sample of twenty-two speeches delivered by members of the Jordanian Parliament the 16th was randomly selected for scrutiny. Three POs detected in their speeches were analyzed at the token level in light of three elementary RT assumptions about discourse connectives in general, namely connectivity, the (...) conceptual-procedural distinction, and monosemy. The major finding of this study was that concessive POs, as a subset of contrastives, are used to optimize relevance: highlight certain dimensions and/or suppress others of the scenario to the background. However, the point of departure from possibly all previous treatments is that the speakers, as politicians, still used them more strategically because total ambiguity resolution should not be a viable alternative in social settings laden with politics.

The editions and source collections of the Series academica provide a basis for research on Byzantine philosophy and education and on the lasting impact of peripatetic philosophy in the Greek middle ages. The series succeeds to the Commentaria in Aristotelem Graeca directed by Hermann Diels and (...) published by the Royal Prussian Academy of Sciences. The publication schedule of the series includes editions of commentaries by Alexander of Aphrodisias, Simplicius, John Philoponus, Michael of Ephesus, Nicephorus Blemmydes, George Pachymeres, Theodore Metochites, George Scholarius, and Bessarion. The series is also open for preliminary studies and companion volumes. https://www.degruyter.com/view/serial/CAGB-B. (shrink)

Somatic complementation by fusion of two mutant cells and mixing of their cytoplasms occurs when the genetic defect of one fusion partner is cured by the functional gene product provided by the other. We have found that complementation of mutational defects in the network mediating stimulus‐induced commitment and sporulation of Physarum polycephalum may reflect time‐dependent changes in the signaling state of its molecular building blocks. Network perturbation by fusion of mutant plasmodial cells in different states of activation, and the time‐resolved (...) analysis of somatic complementation effects can be used to systematically probe network structure and dynamics. Time‐resolved somatic complementation quantitatively detects regulatory interactions between the functional modules of a network, independent of their biochemical composition or subcellular localization, and without being limited to direct physical interactions.

This work identifies the influence of chaos theory on fractional calculus by providing a theorem for the existence and stability of solution in fractional-order gyrostat model with the help of a fixed-point theorem. We modified an integer order gyrostat model consisting of three rotors into fractional order by attaching rotatory fuel-filled tank and provided an iterative scheme for our proposed model as a working rule of obtained analytical results. Moreover, this iterative scheme is injected into algorithms for a system of (...) integer order dynamical systems to observe Lyapunov exponents and a bifurcation diagram for our proposed fractional-order dynamical model. Furthermore, we obtained five equilibrium points, including four unstable spirals and one saddle node, using local dynamical analysis which acted as self-exciting attractors and a separatrix in a global domain.

Source: Author: Marwan Kadhim Mohammed, Wan Roselezam Wan Yahya Martin Amis's manipulation of the patriarchal concept of power is a notable indication of his transgressive attitudes that raise remarkable questions about the human identity. Transgressing power investigates the violation of the normal and familiar trends of literature in order to circulate a new discourse by which a new identity is reframed. Hence, the study of power in Martin Amis's novels, as an important technique of identity re-definition, is not taken (...) into consideration in the light of Foucault's theory of power. The objective of this study is to examine the role applied by transgression as a technique of subverting the common discourse of power in the field of identity re-formation. The study investigates the concept of power manipulated in Amis's Money to define the identity of the 'New Man'. Accordingly, the Foucauldian theory of power is taken as a framework of this study. The study reveals a conclusion in which the transgressive aspects of power are effectively utilized by Amis to re-define the identity of his protagonist in the novel. Although John Self-has finally lost his name and fortune, which are necessary demands to define one's self-in the patriarchal society, he finds his own new identity away from the materialistic norms of the common discourse. ]]>.

This article discusses a scenario of a teenager seeking medical assistance for infertility. Despite its apparent simplicity, the case poses a significant challenge to healthcare professionals. It requires consideration of maternal and child welfare and examination of the legitimate limits of doctors' role vis-à-vis the policy objective of reducing teenage pregnancy rate. The negative stereotypic representation of teenage pregnancy is an important confounding factor.

Our aim here is to show that an enigmatic text of Avicenna's Glosses, devoted to the problem of evil, takes on its full meaning in the light of the last chapter of the Šifā ' on De generatione et corruptione. We will see how Avicenna, deepening and developing a cosmological argument already present in the commentary of Alexander of Aphrodisias on the De generatione, ends up building most of his theodicy on the relative incommensurability of the different celestial periods. All (...) the problem of divine Justice is thus reinterpreted in terms of opposition between discrete and continuous. Finally we will show the importance that this development of Avicenna had in Western Christendom in the 14th century, and the complex relationship which Leibniz has with it in his recently edited reflections on the Great Year.

This article aims to unravel the doctrine of the “sign from the manifest to the hidden” of Abū Hāšim al-Ğubbāʾī. It shows that Abū Hāšim tended to interpret this sign as an inference, of which he recognized two main types: Type-1 proceeds by analytical deduction of concepts by neutralizing the conditions of their realization, i. e. their ontological basis. This is, typically, the procedure most directly consonant with Abū Hāšim's modal ontology. Type-2 exhibits the same causal relationship at the known (...) and unknown levels and considers causality at the known level to be itself the cause of causality at the unknown level. This partition was completely new in philosophy and kalām at the time of Abū Hāšim, but it is foreshadowed in al-Ḫwārizmī’s Algebra. In this book, al-Ḫwārizmī distinguishes between proof “by cause”, which consists in transferring a certain geometric deduction to algebra, and proof “by expression”, which operates directly on algebraic expressions, which it reduces analytically. A text by Abū Hāšim devoted to human knowledge that seems to refer to the work of al-Ḫwārizmī suggests, finally, that the close parallel between al-Ḫwārizmī’s doctrine of proof and Abū Hāšim's doctrine of the sign may not be a mere coincidence. Two appendices have been added. The first deals with al-Fārābī’s reading of Abū Hāšim's theory of inference. The second, based on all available data, establishes for the first time the correct and precise dates of Abū Hāšim's life. (shrink)

The reference to Albinus in a refutation of Bardesanes († c. 222) by Ephrem the Syrian († 373) is not unknown to modern commentators. This text, edited and translated into English since the beginning of the twentieth century, is regularly mentioned, albeit rather cursorily, by scholars of Middle Platonism. Although much has been clarified between the first publication of the book just over a century ago and the present day, the following pages aim to continue the exploration. The aim will (...) be to better understand what has so far remained unnoticed: the dependence of Albinus’ work on Posidonius on three crucial points: (1) his classification of incorporeals, (2) his doctrine of comprehensive representation, and (3) the deep relationship between (1) and (2).

This article proposes a reconstitution of the philosophical tenor of al-Fb al-Mawdayyira). It is shown that this work is not only a response to book VI of John Philoponus' Contra Aristotelem, but that its real issues can only be grasped in the context of the author's metaphysical system. Although, for al-Fbī, genuine demonstrations proceed from the cause to the caused, thus following the order of being, it will be explained how he also admits a strictly physical proof of the simple (...) fact, independently of its cause, and that the physical demonstration of the eternity of the world pertains to this type of proof. This physical proof is specifically directed against the Kindian doctrine of creation. (shrink)

This article aims at reconstructing the most damaged part of the Strasbourg papyrus of Empedocles (fragment f-d), by taking into account all the parameters at our disposal: palaeography, metre and, of course, content. According to this attempt, Empedocles would be describing the very moment in the phase of increasing Strife when the whole-natured creatures (the ολοφυ) were split into male and female beings. Thus, the first part of the fragment becomes very similar, in its content, to fr. 62 D.-K. and (...) to Plato's parody of Empedocles in Aristophanes' myth in the Symposium , while its second part emerges as containing new details of the process by which double creatures were split into two. If this reconstruction is accepted, its implication will be that Aetius' presentation of Empedocles' cosmic cycle as a fourfold continuous process is deeply inadequate. (shrink)

La diffusion d'Alexandre d'Aphrodise, en raison de la qualité inégalée de son exégèse d'Aristote, est celle des textes vivants. Simplicius est plus érudit, Philopon plus critique, Averroès plus savant. Mais Alexandre possédait un art de la synthèse entre l'analyse philologique de la lettre et la saisie de l'orientation générale d'un texte, qui fait de lui l'Exégète par excellence. On comprend, dans ces conditions, que sa transmission ne soit pas le relais linéaire d'un ‘‘témoin” figé. Citons aussi bien le recours extensif (...) de Simplicius, au VIe siècle, à ses commentaires physiques que la renaissance philosophique des IXe–Xe siècles en terre d’Islam, qui s'accompagne d'un mouvement massif de traduction de textes alexandriques. Or s'il apparaît de plus en plus clairement que c'est la nécessité de bâtir une ontologie du sensible aristotélicienne, subordonnée à l'ontologie platonicienne des Formes divines, qui a poussé le ‘‘platonicien” Simplicius à puiser dans les commentaires de son prédécesseur, on ne s’est pas encore assez interrogé sur le sens de l'intérêt aigu des philosophes islamiques pour Alexandre. Pourquoi, par exemple, alors que les Byzantins, quand ils ont eu le choix entre Alexandre et Simplicius, ont choisi Simplicius, les Arabes se sont-ils systématiquement décidés pour Alexandre?

In this article, we use the principlist approach to identify, analyse and attempt to solve the ethical problem raised by a pregnant woman's request for cesarean delivery in absence of medical indications.We use two different types of premises: factual (facts about cesarean delivery and specifically attitudes of obstetricians as derived from the EUROBS European study) and value premises (principles of beneficence and non-maleficence, respect for autonomy and justice).Beneficence/non-maleficence entails physicians' responsibility to minimise harms and maximise benefits. Avoiding its inherent risks (...) makes a prima facie case against cesarean section without medical indication. However, as vaginal delivery can have unintended consequences, there is a need to balance the somewhat dissimilar risks and benefits. The principle of autonomy poses a challenge in case of disagreement between the pregnant woman and the physician. Improved communication aimed to enable better informed choice may overcome some instances of disagreement. The principle of justice prohibits unfair discrimination, and broadly favours optimising resource utilisation.Available evidence supports vaginal birth in uncomplicated term pregnancies as the standard of care. The principlist approach offered a useful framework for ethical analysis of cesarean delivery on maternal request, identified the rights and duties of those involved, and helped reach a conclusion, although conflict at the individual level may remain challenging.

Inconsistent corporate social responsibility (CSR) practices across stakeholder groups may induce undesired consequences for the firm. This study investigates the longitudinal and differential effect of chief executive officer (CEO) tenure on external and internal CSR and the moderating effects of two important contingencies relevant to the firm's social investments: firm visibility and slack availability. It presents CEO tenure as an important upper echelon factor that may induce differential preferences toward external and internal CSR and, therefore, CSR inconsistencies. Accordingly, it proposes (...) two important and relevant contingencies and provides additional evidence on how a firm's visibility and slack availability could affect CEO tenure-related differential behaviors. The findings contribute to studies on the temporal orientations of CEOs and how they impact firm strategic behavior. They also contribute to the literature on firm visibility and slack and how they may interact with certain upper echelon characteristics and affect firm behaviors. The analysis cautions against the perceptions of the relationships between firm- and CEO-level variables and a firm's aggregate CSR. (shrink)

Background Protecting the privacy of research participants is widely recognized as one of the standard ethical requirements for clinical research. It is unknown, however, how research professionals regard concepts of privacy as well as the situations in the research setting that require privacy protections. The aim of this study was to explore the views of research professionals from Arab countries regarding concepts and scope of privacy that occur in clinical research. Methods We adopted an exploratory qualitative approach by the use (...) of focus group discussions. We recruited individuals involved in research from Egypt and Morocco. We analyzed focus group data via a constant comparison approach, which consisted of close reading of the transcribed interviews followed by coding and then determining themes and subthemes. Results Between August 2016 and July 2018, we conducted nine focus group discussions. Respondents discussed several privacy issues that occurred before the research began ; during research, and after the research. Respondents revealed their perspectives of patients towards privacy in the clinical and research settings and mentioned that patients are more likely to permit access to their privacy in the clinical setting compared with research setting due to the existence of benefits and trust in clinical care. Respondents also recommended training regarding data protections for individuals involved in research. Conclusions Our study shows that research professionals discussed a range of privacy issues that are present during the different stages of research. We recommend 1) development of standards regarding privacy protections during recruitment efforts; 2) additional training for individuals involved in research regarding best practices with data security in secondary research; 3) a quantitative study involving investigators and REC members to determine their knowledge, attitudes and practices regarding privacy issues that occur in research; and 4) a quantitative study involving patients to elicit their views regarding their privacy concerns in research.

Le présent article est consacré à la réédition et, pour certaines d’entre elles, à l’édition de scholies byzantines comportant des données chiffrées sur les périodes du cycle d’Empédocle. Celles-ci ont été copiées au xii e siècle sous forme de gloses à différents traités d’Aristote. On s’attachera à démontrer la cohérence interne de ces nouveaux renseignements, leur compatibilité avec les fragments conservés du poème Sur la nature et, enfin, on suggérera un canal possible de transmission.

In seiner Schrift "De generatione et corruptione" entwickelt Aristoteles seine Antworten auf die Aporien, die sich aus dem Begriff des Werdens ergeben. Dabei geht es ihm ebenso darum, analytisch - und dies im angelsachsischen Sinne des Wortes - das gesamte Bedeutungsspektrum des griechischen Verbes "genesthai" zu klaren und zu ordnen, wie darum, auf rein physikalischer Ebene allgemeine Betrachtungen zur Einfuhrung in die physiologischen Studien des biologischen Corpus anzustellen.Die philosophische Uberlieferung hat, mehr oder minder bewusst, immer erkannt, dass es in Aristoteles (...) Schrift um die Machbarkeit und den Platz einer physikalischen Untersuchung des Lebendigen ging und - unter monotheistischen Vorzeichen - um das Verhaltnis Gottes zu seinen Geschopfen. Man denke nur an den Ps.-Okellos in hellenistischer Zeit, ferner an die galenische Tradition und an die bahnbrechenden physikalischen Intuitionen des Alexander von Aphrodisias. Man denke auch an die grosse Anziehungskraft, die dieser Text auf die arabischen Philosophen und spater auf die Physiker-Arzte Suditaliens ausgeubt hat. Und man denke schliesslich an die fast siebzig byzantinischen Manuskripte, die uns den Text des Traktats in der Originalsprache uberliefert haben. All das zeugt von der Faszination, die dieser Text auf Denker ausgeubt hat, die zu verstehen versucht haben, warum und wie die Welt der reinen Potenz und Materie unter bestimmten, sehr spezifischen Bedingungen in die Individualisierung der aktualisierten Form munden kann.Auch die Gegner waren sich der Bedeutung des Textes bewusst. So hat Philoponus den Traktat nicht ausdrucklich verworfen, wenn er auch in seinem De Aeternitate mundi contra Aristotelem und seinem De Aeternitate munde contra Proclum die These von der Ewigkeit der Welt und dem Fortbestand der Arten ablehnt, der ja, wie wir gerade gesehen haben, in dem Traktat eine grundlegende Bedeutung zukommt. Eine systematische Widerlegung von De generatione et corruptione wird erstmals von einem der grossten islamischen Theologen zu Anfang des 10. Jahrhunderts gefuhrt. Der Autor zeigt unter anderem, dass die wichtigste unter den drei arabischen Ubersetzungen sehr wahrscheinlich auf das byzantinische Exemplar der physikalischen Traktate zuruckgeht, dass die suditalienischen Arzte es nicht versaumt haben, sich unverzuglich die vielfaltigen, von Burgundio von Pisa zusammen mit seiner Version ubersetzten Randnotizen zunutze zu machen, - dass ubrigens die beiden Manuskripte, die mit Suditalien in Verbindung gebracht werden konnen, jeweils medizinische Texte enthalten -, dass zahlreiche byzantinische Gelehrte es sich haben angelegen sein lassen, den Text durch oft interessante, zuweilen brillante Konjekturen zu verbessern.Der Autor liefert mit seiner Uberlieferungsgeschichte also nicht nur das fur eine wirklich textkritische Ausgabe unerlassliche Stemma. Er fuhrt uns ebenso die Vielgestaltigkeit der Geschichte der Philosophie vor Augen, die sich ebenso mit der Theologie wie mit den Naturwissenschaften befasst. Nur die Uberlieferungsgeschichte kann uns vor historischen Trugbildern bewahren, d. h. vor der pseudo-philosophischen Rekonstruierung riesiger Phantasiefresken. (shrink)

This article revisits the controversy between Abū Bakr al-Rāzī and Abū al-Qāsim al-Balḫī. Based on the testimony of the Kitāb taṯbīt dalāʾil al-nubuwwa of the Qāḍī ʿAbd al-Ǧabbār, it is shown that the two philosophers must have clashed at the court of Aḥmad b. Sahl al-Marwazī, governor of Balḫ, during the 910s, and that the virulence of the tone of their exchange can be explained above all by this context of professional rivalry. In terms of content, their conversation must have (...) focused on the question of divine justice and on the best way to give an account of prophecy and Qurʾanic wisdom. We then turn to the study of chap. VIII, 4 of Faḫr al-Dīn al-Rāzī's Al-maṭālib al-ʿāliya and show that, contrary to a recently held view, this chapter constitutes an echo not of Abū Bakr al-Rāzī, but of the first argument of Ibn al-Rāwandī's Kitāb al-zumurrud, which contrasted the autonomy of reason with the necessity of prophecy in order to conclude from the former to the negation of the latter. Finally, it is suggested that Abū Bakr al-Rāzī's doctrine of prophecy, like that of the great theologians of his time, both Muʿtazilites and Ašʿarites, aims to escape the dilemma set up by Ibn al-Rāwandī a few decades earlier.
