Norms provide a valuable mechanism for establishing coherent cooperative behaviour in decentralised systems in which there is no central authority. One of the most influential formulations of norm emergence was proposed by Axelrod :1095–1111, 1986). This paper provides an empirical analysis of aspects of Axelrod’s approach, by exploring some of the key assumptions made in previous evaluations of the model. We explore the dynamics of norm emergence and the occurrence of norm collapse when applying the model over extended durations. It (...) is this phenomenon of norm collapse that can motivate the emergence of a central authority to enforce laws and so preserve the norms, rather than relying on individuals to punish defection. Our findings identify characteristics that significantly influence norm establishment using Axelrod’s formulation, but are likely to be of importance for norm establishment more generally. Moreover, Axelrod’s model suffers from significant limitations in assuming that private strategies of individuals are available to others, and that agents are omniscient in being aware of all norm violations and punishments. Because this is an unreasonable expectation, the approach does not lend itself to modelling real-world systems such as online networks or electronic markets. In response, the paper proposes alternatives to Axelrod’s model, by replacing the evolutionary approach, enabling agents to learn, and by restricting the metapunishment of agents to cases where the original defection is observed, in order to be able to apply the model to real-world domains. This work can also help explain the formation of a “social contract” to legitimate enforcement by a central authority. (shrink)

One of the main arguments intended to show that content externalism undermines the privileged access thesis is the ‘slow switching argument’, originally proposed by Boghossian. In this argument, it is supposed that a subject is unknowingly switched back and forth between Earth and Twin Earth: then it is claimed that, given externalism, when the subject is on Earth thinking that water is wet, he cannot know the content of his thought a priori, for he cannot, by mere reflection, rule out (...) the relevant alternative hypothesis that he is on Twin Earth thinking that twater is wet. One of the controversies surrounding this argument stems from the fact that it is not clear which epistemological principle underlies it. Here, I examine two suggestions made in the literature as to what that underlying principle might be. I argue that neither of these suggested principles is plausible, and thus that the slow switching argument never gets off the ground. (shrink)

Ibadiyya is one of the earliest Islamic sects and one of the few to have survived to the present day. The Ibadiyya sect is still active in many places, including Tanzania, the Sultanate of Oman, and North Africa. Despite all of this information, fewer studies on Ibadis exist than on other extant and non-member sects. An Islamic group known as the Ibadiyya first appeared following the so-called “great acts of sedition” (büyük fitne) in the first century AH. This group initially (...) supported the Kharijites, but over time, it gradually shifted away from them in terms of politics and mindset. Even though the Kharijites were exterminated from the historical scene at an early age, the Ibadis have survived until the present. However, according to many researchers, the Ibadis still exist as a branch of the Kharijites. In this study, the theological thoughts of North African Ibadis are discussed. Since the Ibadis and Kharijites generally held different ideological and political perspectives. And the North African Ibadis in particular are distinguished from the Kharijites as well as from the general Ibadis by their differences. And it is essential to understand the underlying and guiding thinking behind these differences in order to understand their essence. (shrink)

Despite the increasingly diversified discourses in international commercial arbitration, this device of socio-legal regulation remains a relatively under-theorized subject. In particular, far too little attention has been paid to analyzing international commercial arbitration through critical approaches such as Third World Approaches to International Law (TWAIL). TWAIL is broadly understood as a methodological reorientation in international law by highlighting the historical links between the foundations of this field of law and the history of capitalism and imperialism as well as the colonial (...) and Eurocentric legacies in the structure and operation of the current international legal regime. With this in mind, two fronts in international commercial arbitration invite a reexamination through a TWAIL perspective and by drawing on the concept of hegemony. One front is the transnational account of arbitration, and the other one is the epistemic community of arbitration. By examining these two notions through a narrative of hegemony of Western legal traditions, we posit that any effective attempt at redefining or reforming arbitral governance structure towards sustaining diversity requires a deeper understanding of historical and current world power structures and creating a vision for the prospect of dehegemonization.

Introduction: If ever attained, adopting native-like accent is achieved late in the learning process. Resemblance between L2 and mother tongue can facilitate L2 learning. In particular, cognates (phonologically and semantically similar words across languages), offer the opportunity to examine the issue of foreign accent in quite a unique manner. Methods: Twelve Spanish speaking (L1) adults learnt French (L2) cognates and practiced their native-like pronunciation by means of a computerized method. After consolidation, they were tested on L1 and L2 oral picture- (...) naming during fMRI scanning. Results and Discussion: The results of the present study show that there is a specific impact of accent on brain activation, even if L2 words are cognates, and belong to a pair of closely related languages. Results point that the insula is a key component of accent processing, which is in line with reports from patients with foreign accent syndrome (FSA) following damage to the insula (e.g. Moreno-Torres et al., 2013; Katz et al., 2012; Tomasino et al., 2013), and healthy L2 learners (Chee et al., 2003). Thus, the left insula has been consistently related to the integration of attentional and working memory abilities, together with fine-tuning of motor programming to achieve optimal articulation.

In the past decade, the use of the Chapter XI has soared to the detriment of many creditors, workers, and consumers. A good number of cases were not based on imminent insolvency, but on firms attempts to avoid litigation claims against them, to terminate labor or other contractual obligations, or to gain new financing.These filings for Chapter XI highlight the use of bank-ruptcy as a strategic option used by management in running a viable organization. This usage is even advised by (...) some academics and management consultants. (shrink)

This article is aimed to rephrase and critique the arguments presented by Joseph LaPorte about the truth of theoretical identity statements in natural sciences. LaPorte is classified as an essentialist who accepts the real kinds, but he denies the essence of the kinds to be discovered. His arguments are based on the vagueness of the terms of kinds. In his view while science progress we convention (not discover) what is related to the kinds. I evaluate LaPorte's arguments and show they (...) can be applied only for the border terms in scientific theories and so the generalization of the claim is not defensible. (shrink)

In this paper a symmetry argument against quantity absolutism is amended. Rather than arguing against the fundamentality of intrinsic quantities on the basis of transformations of basic quantities, a class of symmetries defined by the Π-theorem is used. This theorem is a fundamental result of dimensional analysis and shows that all unit-invariant equations which adequately represent physical systems can be put into the form of a function of dimensionless quantities. Quantity transformations that leave those dimensionless quantities invariant are empirical and (...) dynamical symmetries. The proposed symmetries of the original argument fail to be both dynamical and empirical symmetries and are open to counterexamples. The amendment of the original argument requires consideration of the relationships between quantity dimensions. The discussion raises a pertinent issue: what is the modal status of the constants of nature which figure in the laws? Two positions, constant necessitism and constant contingentism, are introduced and their relationships to absolutism and comparativism undergo preliminary investigation. It is argued that the absolutist can only reject the amended symmetry argument by accepting constant necessitism. I argue that the truth of an epistemically open empirical hypothesis would make the acceptance of constant necessitism costly: together they entail that the facts are nomically necessary. (shrink)

In this paper, by considering the notions of effect algebra and product effect algebra, we define the concept of effect module. Then we investigate some properties of effect modules, and we present some examples on them. Finally, we introduce some topologies on effect modules.

Technostress is evolving as an imperative area of academic research amid the “new normal” settings of working remotely. Research has investigated the relationships between technostress and job outcomes and proposed individual- and organizational-level approaches to manage it. However, insights into the influence of dynamic personality differences on this relationship are limited. This study ties the concept of self-efficacy to the transactional model of stress and coping, and investigates to what extent computer and social self-efficacy moderate the relationships between technostress creators (...) and frontline employee’s job performance. Findings shift the focus from the negative aspects of technostress and outcomes to both positive and negative aspects. This study’s contributions and implications for theory and practice are discussed. (shrink)

This book explores the spiritual potential of faith, mysticism and transcendence in answer to the dangers of a mythologised state and the sacro-sanctification of (liberal) democracy and its rule of law. It searches for a curative for the pathological transformation of these institutions into--so called--political religions. Along this line, it explores the importance of spirituality and transcendence for political legitimacy, democratic participation and international cooperation, law and politics. There being no general agreed-upon definition of 'spirituality', the authors examine what may (...) be seen as 'spiritual' dimensions of the political. These dimensions have in common a focus on transcendence as a vanishing point of rationality and rational justification. This vanishing point may become manifest, for example, in a primordial requisite of becoming an individual person; in responding--in freedom--to the call of theocracy; in the phenomenon of prophecy or political wisdom; in the remaining shards of formerly all-pervasive religious institutions; in tenacious hope for a democracy-to-come; in the courageous resilience and resistance of citizens of 'non-' or 'un-democratic' states; etc."--Page 4 of back cover.

Objectivity is one of the most basic and difficult issues in modern and contemporary philosophy. The present paper is devoted to this issue from view- point of Husserl’s transcendental phenomenology. Since perception, particularly sense perception, in view of intentionality, as lowest level of objectivity can act as the base for perceiving the objectivity of other objects, whether real or unreal, it has been discussed in this paper. To do this, objectivity of the sense perception and its role in leading the (...) mind toward essential and ideal objects, and conversely, the role of latter objects in objectivity of the perception itself will be explored. Because the concepts of objectivity and evidence are correlate in Husserl’s philosophy, and since evidence as the self-given manifests itself, from the very beginning, in the lowest level, namely the objects of sense perception, and considering that evidence and objectivity of sense perception concern this lowest level, the critical viewpoint of Husserl’s phenomenology provides a firm and new basis for objectivity if taken at its full competence.

Given the evolution of the public health (PH) and the changes from the phenomenon of globalization, this area has encountered new ethical challenges. In order to find a coherent approach to address ethical issues in PH policy, this study aimed to identify the evolution of public health ethics (PHE) frameworks and the main moral values and norms in PH practice and policy. According to the research questions, a systematic search of the literature, in English, with no time limit was performed (...) using the main keywords in databases Web of Science (ISI) and PubMed. Finally, the full text of 56 papers was analyzed. Most of the frameworks have common underpinning assumptions and beliefs, and the need to balance PH moral obligation to prevent harm and health promotion with respect for individual autonomy has been specified. As such, a clear shift from liberal values in biomedical ethics is seen toward the community’s collective values in PHE. The main moral norms in PH practice and policy included protecting the population against harm and improving PH benefits, utility and evidenced-based effectiveness, distributive justice and fairness, respect for all, privacy and confidentiality, solidarity, social responsibility, community empowerment and participation, transparency, accountability and trust. Systematic review of PHE frameworks indicates utilization of the aforementioned moral norms through an practical framework as an ethical guide for action in the PH policy. The validity of this process requires a systematic approach including procedural conditions. (shrink)

I provide an account of the physical appropriate to the task of the physicalist while remaining faithful to the usage of “physical” natural to physicists. Physicalism is the thesis that everything in the world is physical, or reducible to the physical. I presuppose that some version of this position is a live epistemic possibility. The physicalist is confronted with Hempel’s dilemma: that physicalism is either false or contentless. The proposed account of the physical avoids both horns and generalizes a recent (...) proposal by Vicente (2011). My account defines physicalism as the thesis that there are no objects that cannot be described by physical quantities. A dimensional account of physical quantities is given: quantities are determined by measurement procedures. (shrink)

This article exploits the synergy of critical discourse studies and Corpus Linguistics to study the pervasive representation of Islam and Muslims in an approximate 670,000-word corpus of US news media stories published between 2001 and 2015. Following collocation and concordance analysis of the most frequent topics or categories which revolve around the representation of Islam and Muslims in US news stories, the Discourse-Historical Approach to critical discourse analysis was adopted to investigate how the discursive strategies of nomination and predication are (...) used in US news media stories. The findings indicated that, in general, Islam and Muslims are associated with violence, religious radicalism, and Islamic extremist militants. Finally, the article discusses the discursive themes resulting from the analysis of personal pronouns as well as the educational implications of the findings for social studies and multicultural education.

In many areas, technology has facilitated many things, diagnosing diseases, regulating traffic and teaching students in schools rely on Intelligent systems to name a few. At present, traditional classroom-based education is no longer the most appropriate in schools. From here, the idea of intelligent e-learning for students to increase their culture and keep them updated in life began. E-learning has become an ideal solution, relying on artificial intelligence, which has a footprint in this through the development of systems based on (...) education without a teacher taking into account the individual differences of students. This study describes intelligent tutoring system for teaching the Data Manipulation Language (DML) Commands Using SQLite to non IT students to overcome the difficulties they face. The System was built as education system by using the researcher own authoring tool that based on mobile and web App. The basic idea of this system is a systematic introduction into the concept of Database and its DML query. The system presents the topic of DML Commands, help student to execute what they are learn from the system content using the practical part of the system and administers automatically adapted at run time to the student’s individual growth. The system was assessed by a group of teachers and students and the outcome showed as 91% from the database specialists, 94% from Diploma students group and 89% from the secondary school students group.

The question of the meaning of life is one of the fundamental issues that humanity was asking since the beginning of its creation. Among various approaches to addressing the issue of meaning of existence, one of the primary methods is the philosophical approach. Meanwhile, Islamic philosophy, when confronted with the question of the meaning of life, establishes its foundation upon the understanding of human capacities and capabilities. It asserts that the answer to the question of the origin of life can (...) only be achieved through recognizing human nature, which with its faculty of intellect, tends to discover truth and the meaning of life. Islamic philosophy does not view human life as separate from the system of the universe. Instead, it seeks to find the meaning of lifewithin this framework and a specific context. The significance, value, and credibility of human life are based on its interpretation of the universe and its connection to the ultimate purpose. Therefore, meaningfulness is contingent upon the humans' relationship with the ultimate purpose of the universe. In this article, I examine the perspective of Islamic philosophy on the meaning of life based on its definition of the human being and the universe. (shrink)

Abstract: Tomatoes are part of the major crops in food security. Tomatoes are plants grown in temperate and hot regions of South American origin from Peru, and then spread to most countries of the world. Tomatoes contain a lot of vitamin C and mineral salts, and are recommended for people with constipation, diabetes and patients with heart and body diseases. Studies and scientific studies have proven the importance of eating tomato juice in reducing the activity of platelets in diabetics, which (...) helps in protecting them from developing deadly blood clots. A tomato classification approach is presented with a data set containing approximately 5,266 images with 7 species belonging to tomatoes. The Neural Network Algorithms (CNN), a deep learning technique applied widely in image recognition, is used for this task. (shrink)

A sophisticated version of the zombie argument due to David Chalmers runs roughly as follows: a zombie world is ideally primarily conceivable, and whatever is ideally primarily conceivable is primarily possible. Thus, a zombie world is primarily possible, which implies, in turn, that either physicalism is false or Russellian monism is true. Appealing to some plausible mereological considerations, Daniel Giberman presents a novel argument to the effect that zombies are not ideally primarily conceivable. I shall argue, firstly, that a main (...) premise of Giberman's argument is ill-supported, as it trades on a confusion between the primary and the secondary intensions of the "actually" operator. I then consider two lines of reasoning, which might be extracted from Giberman's text, in favour of another chief premise of his argument. I shall argue that the first line of reasoning is flawed, and the second one, in effect, will transform Giberman's argument into a kind of "parity argument" in which his mereological considerations play no role.

Several lines of reasoning have been proposed to show the incompatibility of content externalism with justification internalism. In this paper I examine two such lines of reasoning, which both rely on the general idea that since content externalism is incompatible with certain aspects of the alleged privileged character of self-knowledge, it would tend to undermine justification internalism as well. I shall argue that both lines of reasoning, as they stand, lack plausibility, though the core idea of the second line can (...) be reconstructed into a new argument which shows considerable promise. In particular, relying upon the reliability constraint on knowledge, I shall argue that the so-called ‘two-concept’ version of content externalism is incompatible with ‘the transparency of sameness of content’, and thereby would also undermine justification internalism.

The Coronavirus pandemic has been ongoing for almost two years now. Not only did it surprise the whole world in the initial stages of its occurrence, but also the world left it in shock. Therefore, the instant solution strategies included complete lockdowns in order to prevent the spread of such a disease. However, as the lockdowns lasted longer, it generated negative psychological effects on people globally. This being the case, collective endeavors and efforts were performed, in the hope of achieving (...) a concrete solution in order to overcome the bad repercussions that seemed visible on societal levels, which of course, included religious aspects; and in some cases resulted in social separation as well as a dramatic rise in suicide rates. On the one hand, this caused a retraction from the religion and religiously oriented rituals, but on the other hand, it also made people turn more to religion as it provided a psychological relief from the heavy burdens of the pandemic. These psychological conditions had theological resonances that made already complicated issues even more complex. Among them, the nature of God’s actions and the human position in this matter can be given as examples. This article is an attempt to place and define the issue of the pandemics and plagues from the perspective of Islamic theology, in particular, to shed light on three main points. The first is the problem of pains and aches, and how it was mentioned in theological literaturey and discussed by Islamic theologians (Mutakallimūn), as the issue of pandemics and plagues indisputably fall under this matter. The second point tackles the problem of whether “such calamities as pandemics and plagues come from God's Decree, or not?”. The last point focuses on the issue of fatalism and tries to show whether the de facto acceptance that pandemics are from God’s Decree would require the servant to stop taking measures in response to them. To answer the questions at stake, this paper will focus on four different perspectives of the Mu’tazila, Ash‛arī s, Māturīdis, and Ahl al-Hadīth, by using a selective methodology and focusing on their prominent and pioneering theologians (Mutakallimūn) of these schools.

One of the main issues concerning different versions of content externalism is whether or not they are compatible with the privileged access thesis. According to the so-called ‘illusion version’ of externalism, in reference failure cases (such as cases in which an empty proper name is involved) the subject suffers an illusion of entertaining a thought. In this paper, I shall concentrate on a recent argument offered by Jessica Brown, which she calls the “illusion argument”, to the effect that the illusion (...) version of externalism undermines the privileged access thesis (Brown, 2004). After criticizing Brown's argument, I shall try to reconstruct the illusion argument in a more defensible and straightforward way. I will exploit, in my argument, solutions proposed by Goldman and Alston for the so-called ‘generality problem’ (Goldman, 1986; Alston, 1995). Moreover, I shall offer a stronger formulation of the global reliability condition for knowledge, upon which my reconstruction of the illusion argument is based. (shrink)

Mansour Fahmy's creativity was at one of the sensitive stages in Egypt's modern history in which the political, social, national, cultural, and revolution clashed in each one. All this, in turn, identified the problem of Mansour Fahmy's intellectual personality in the battles of thought and politics. This research's main task is to redraw the features of his actual personality and the reality of his intellectual, social, and political positions. Besides, this study seeks to uncover the effect of philosophy on crystallizing Mansour Fahmy's critical personality and its role in laying the foundations of the critical vision with its practical, reformist, and enlightening dimensions.

Dierig also considers, and criticizes, a modified version of the discrimination argument which would be immune to his objection. I shall argue, first, that he fails to advance a successful objection to the (...) original version of the argument; and, second, that his criticism of the modified version is misconceived. (shrink)

This paper ascertains genuine principles of Islam while exploring an emerging contradiction between authentic tenets of faith in the Muslims’ heritage of human rights and justice, and a variety of modern targets upheld by OIC Charter and other political and legal instruments to guide a far-sighted authority agenda in pursuit of global equilibrium over key Muslim concerns.

Tatiana Ehrenfest-Afanassjewa was an important physicist, mathematician, and educator in 20th century Europe. While some of her work has recently undergone reevaluation, little has been said regarding her groundbreaking work on dimensional analysis. This, in part, reflects an unfortunate dismissal of her interventions in such foundational debates by her contemporaries. In spite of this, her work on the generalized theory of homogeneous equations provides a mathematically sound foundation for dimensional analysis and has found some appreciation and development. It remains to (...) provide a historical account of Ehrenfest-Afanassjewa's use of the theory of homogeneous functions to ground (and limit) dimensional analysis. We take as a central focus Ehrenfest-Afanassjewa's contributions to a debate on the foundations of dimensional analysis started by physicist Richard Tolman in 1914. I go on to suggest an interpretation of the more thoroughgoing intervention Ehrenfest-Afanassjewa makes in 1926 based on this earlier context, especially her limited rehabilitation of a "theory of similitude" in contradistinction to dimensional analysis. It is shown that Ehrenfest-Afanassjewa has made foundational contributions to the mathematical foundations and methodology of dimensional analysis, our conception of the relation between constants and laws, and our understanding of the quantitative nature of physics, which remain of value.

Ubuntu has been defined as a moral quality of human beings, as a philosophy or an ethic, as African humanism, and as a worldview. This paper explores these definitions as conceptual tools for understanding the cultural, educational, and philosophical landscape of post-apartheid South Africa. Key to this understanding is the Althusserian concept of state apparatus. Louis Althusser divides the state apparatus into two forces: the repressive state apparatus (RSA); and the ideological state apparatus (ISA). RSAs curtail the working classes, predominately (...) through direct violence or the threat of violence, whereas ISAs function primarily by ideology, including forms of organised religion, the education system, family units, legal systems, trade unions, political parties, and media. This paper discusses the link between increasing inequality in post-apartheid South Africa and education, with specific reference to Althusser’s ISAs and the abuse of Ubuntu as a subterfuge for socio-economic inequality.
