This research implements a recent evolutionary-based algorithm of equilibrium optimizer to resolve the constrained combined economic emission dispatch problem. This problem has two objective functions that represent the minimizing of generation costs and minimizing the emission of environmental pollution caused by generators. The proposed algorithm integrates the dominant criteria for multiobjective functions that allow the decision-maker to detect all the Pareto boundaries of constrained combined economic emission dispatch problem. In order to save the effort for the decision-maker to select the (...) best compromise alternative, a cluster study was carried out to minimize the size of the Pareto boundary to an acceptable size, representing all the characteristics of the main Pareto frontier. On the other hand, in order to deal with the infringement of constraints, a repair algorithm was used to preserve the viability of the particles. The proposed algorithm is applied to solve the standard 30-bus IEEE system with 6 generators to validate its robustness and efficiency to produce a well-distributed Pareto frontier for constrained combined economic emission dispatch problem. Compared with other studies, good results in solving constrained combined economic emission dispatch problem are obtained and a reasonable reduced Pareto set is found. (shrink)

The study investigates the effect of board characteristics and firm performance on disclosure tones by considering DICTION five master variables namely activity, optimism, certainty, realism and commonality tones using a sample of 779 annual reports of GCC listed firms (2012 to 2018). Disclosure tones of the sampled GCC firms were measured through corporate narrative disclosures by DICTION 7.0 software. Then, the ordinary least square regression analysis was conducted. The main findings of the study show that firm performance has a significant (...) effect on disclosure tones in terms of activity, optimism, certainty, and realism tones except for commonality reported tone. Board characteristics have different effects on the five disclosure tones. The study offers a unique contribution to accounting literature as it is one of the first studies in the Gulf region that seeks to examine the relationship between disclosure tones and firm performance as well as board governance.

The relationship between Peircean abduction and the modern notion of Inference to the Best Explanation is a matter of dispute. Some philosophers, such as Harman :88–95, 1965) and Lipton, claim that abduction and IBE are virtually the same. Others, however, hold that they are quite different :503, 1998; Minnameier in Erkenntnis 60:75–105, 2004) and there is no link between them :419–442, 2009). In this paper, I argue that neither of these views is correct. I show that abduction and IBE have (...) important similarities as well as differences. Moreover, by bringing a historical perspective to the study of the relationship between abduction and IBE—a perspective that is lacking in the literature—I show that their differences can be well understood in terms of two historic developments in the history of philosophy of science: first, Reichenbach’s distinction between the context of discovery and the context of justification—and the consequent jettisoning of the context of discovery from philosophy of science—and second, underdetermination of theory by data.

I examine and resolve an exegetical dichotomy between two main interpretations of Peirce’s theory of abduction, namely, the Generative Interpretation and the Pursuitworthiness Interpretation. According to the former, abduction is the instinctive process of generating explanatory hypotheses through a mental faculty called insight. According to the latter, abduction is a rule-governed procedure for determining the relative pursuitworthiness of available hypotheses and adopting the worthiest one for further investigation—such as empirical tests—based on economic considerations. It is shown that the Generative Interpretation (...) is inconsistent with a fundamental fact of logic for Peirce—i.e., abduction is a kind of inference—and the Pursuitworthiness Interpretation is flawed and inconsistent with Peirce’s naturalistic explanation for the possibility of science and his view about the limitations of classical scientific method. Changing the exegetical locus classicus from the logical form of abduction to insight and economy of research, I argue for the Unified Interpretation according to which abduction includes both instinctive hypotheses-generation and rule-governed hypotheses-ranking. I show that the Unified Interpretation is immune to the objections raised successfully against the Generative and the Pursuitworthiness interpretations. (shrink)

Many non-physicalists, including Chalmers, hold that the zombie argument succeeds in rejecting the physicalist view of consciousness. Some non-physicalists, including, again, Chalmers, hold that quantum collapse interactionism, i.e., the idea that non-physical consciousness causes collapse of the wave function in phenomena such as quantum measurement, is a viable interactionist solution for the problem of the relationship between the physical world and the non-physical consciousness. In this paper, I argue that if QCI is true, the zombie argument fails. In particular, I (...) show that if QCI is true, a zombie world physically identical to our world is impossible because there is at least one law of nature, a fundamental law of physics in particular, that exist only in the zombie world but not in our world. This shows that philosophers like Chalmers are committing an error in endorsing the zombie argument and QCI at the same time. (shrink)

I argue that if simplicity is a theoretical virtue and some theoretical virtues are the constituents of the aims of theorizing in physics—i.e., theory choice and theory development in physics—and scientific rationality is instrumental rationality, then simplicity cannot be a mere means to achieve the aims. I do this by showing that considering simplicity as a mere means brings about counterintuitive ramifications concerning scientific rationality. These counterintuitive ramifications can be avoided if we consider simplicity a constituent of the aims of (...) theorizing in physics. (shrink)

Bird reveals an important problem at the heart of Armstrong’s theory of laws of nature: to explain how a law necessitates its corresponding regularity, Armstrong is committed to a vicious regress. In his very brief response, Armstrong gestures towards an argument that, as he admits, is more of a “speculation.” Later, Barker and Smart argue that a very similar problem threatens Bird’s dispositional monist theory of laws of nature and he is committed to a similar vicious regress. In this paper, (...) first, I construct Armstrong’s would-be argument in response to Bird. Second, I argue that his response makes his account of laws and natural properties incompatible with science. Finally, I argue that Armstrong’s strategy to address Bird’s criticism can be used, quite ironically, to defuse Barker and Smart’s argument against Bird. (shrink)

Multiculturalism has become a central theme in many academic disciplines from philosophy to education, social work and psychology, ultimately reaching political science and law. What seems to be unique in current studies on multiculturalism is not merely the observance and display of societies that happen to be diverse in terms of the religious, cultural, national and ethnic affiliation of their members. Rather, it is the central argument that such divergence is legitimate and should be accommodated. Accepting other groups in society (...) and the legitimacy of accommodating them has become a virtue of tolerance.This paper argues that we must first look into multicultural theory itself to discover what can be called ‘multicultural qualifications’. These are in essence pre-conditions without the presence of which group accommodations, even if granted based on group membership, should not be considered as multicultural in nature. With multicultural theory as a backdrop, this article intends to identify such multicultural qualifications. The Palestinian-Arab minority in Israel is studied in its constellation as both a national minority group and as a religiously diverse group as an object for testing the application of the identified multicultural qualifications.

PurposeThe purpose of this paper was to develop a framework of working-together relations and investigate ways to enhance working-together relations among people, organisations, communities and neighbourhoods using working-together applications. Today, people in communities, neighbourhoods and constituencies often work together in a coalition of public, private and non-profit institutions. The technology used today has enabled new forms of communications and collaboration. The rapid growth of mobile technologies and interactive, collaborative applications based on Web technologies has enabled the development of new approaches (...) to derive and share organisational and local knowledge. Not all of these applications have succeeded; after a certain time, users tend to stop using online applications that do not assist them in developing collaborative practices with their team members.Design/methodology/approachTo better understand the essential characteristics of a successful online application that effectively supports people to work together, the authors undertook an inductive analysis of related literature and existing social media application.FindingsBy combining and categorising the findings, it was possible to articulate the characteristics associated with four identified categories of working-together relations: networking, coordination, cooperation and collaboration. The study also identified essential activities that are performed in each working-together category and the factors that enable successful working-together relations: trust, risk and rewards.Research limitations/implicationsFuture studies will look into how applications could be further enhanced, so that, for example, an application that is currently classified as “coordination” could be improved and the required characteristics of “collaboration” could be met.Practical implicationsIt is expected that the framework derived will assist in the design of successful online applications to support different categories of working-together relations.Originality/valueThe main contribution of this study is a new framework that can now be used to identify how effective an existing application can be in assisting the working-together relations.

The purpose of this book is to trace the main developments in Greek philosophy during the period which runs from the death of Alexander the Great in 323 B.c. to the end of the Roman Republic. These three centuries, known to us as the Hellenistic Age, witnessed a vast expansion of Greek civilization eastwards, following Alexander's conquests; and later, Greek civilization penetrated deeply into the western Mediterranean world assisted by the political conquerors of Greece, the Romans. But philosophy throughout this (...) time remained a predominantly Greek activity. The most influential thinkers in the Hellenistic world were Stoics, Epicureans and Sceptics. This book gives a concise critical analysis of their ideas and their methods of thought. The last book in English to cover this ground was written sixty years ago. In the interval the subject has moved on, quite rapidly since the last war, but most of the best work is highly specialized. There is a clear need for a general appraisal of Hellenistic philosophy which can provide those who are not specialists with an up-to-date account of the subject. Hellenistic philosophy is often regarded as a dull product of second-rate thinkers who are unable to stand comparison with Plato and Aristotle. This book will help to remove such misconceptions and arouse wider interest in a field which is fascinating both historically and conceptually. (shrink)

Background: Increasing collaboration between industrialised and developing countries in human research studies has led to concerns regarding the potential exploitation of resource deprived countries. This study, commissioned by the former National Bioethics Advisory Commission of the United States, surveyed developing country researchers about their concerns and opinions regarding ethical review processes and the performance of developing country and US international review boards .Methods: Contact lists from four international organisations were used to identify and survey 670 health researchers in developing countries. (...) A questionnaire with 169 questions explored issues of IRB review, informed consent, and recommendations.Results: The majority of the developing country researchers were middle aged males who were physicians and were employed by educational institutions, carrying out research on part time basis. Forty four percent of the respondents reported that their studies were not reviewed by a developing country IRB or Ministry of Health and one third of these studies were funded by the US. During the review process issues such as the need for local language consent forms and letters for approval, and confidentiality protection of participants were raised by US IRBs in significantly higher proportions than by host country IRBs.Conclusion: This survey indicates the need for the ethical review of collaborative research in both US and host countries. It also reflects a desire for focused capacity development in supporting ethical review of research. (shrink)

The objective of this paper is to develop neutrosophic quadruple algebraic hyperstructures. Specifically, we develop neutrosophic quadruple semihypergroups, neutrosophic quadruple canonical hypergroups and neutrosophic quadruple hyperrings and we present elementary properties which characterize them.

The philosophy of Epictetus, a freed slave in the Roman Empire, has been profoundly influential on Western thought: it offers not only stimulating ideas but practical guidance in living one's life. A. A. Long, a leading scholar of later ancient philosophy, gives the definitive presentation of the thought of Epictetus for a broad readership. Long's fresh and vivid translations of a selection of the best of Epictetus' discourses show that his ideas are as valuable and striking today as they were (...) amost two thousand years ago. This is a book for anyone interested in what we can learn from ancient philosophy about how to live our lives. (shrink)

Background: The magnitude of bullying and harassment among psychiatrists is reportedly high, yet no peer-review published studies addressing this issue could be found. Therefore, it was decided to conduct a pilot study to assess the degree of the problem, the types of bullying/harassment and to provide some insights into the situation.Methods and Principal Findings: Following multiple focus group meetings, a yes/no response type questionnaire was developed to assess the degree and type of bullying and harassment experienced by psychiatrists. Over a (...) 3-month period the questionnaire was administered to a random sample of 60 psychiatrists. 57 out of the 60 psychiatrists reported harassment and bullying. Frequencies of the following response variables are presented in descending order: rumours 40% ; defamation 20% ; passing remarks 20% ; false accusations 15% ; threats 13.3% ; verbal abuse 13.3% ; unjustified complaints 13.3% ; promotion blocked 13.3% ; humiliation 13% ; bad reference given 10% ; credentials questioned 8.3% ; physical attacks 5% ; termination 5% ; derogatory remarks 1.7% and 1.7% were subjected to personal work. As a result of being subjected to harassment, 66.7% of the psychiatrists did not take any action, whereas 33.3% confronted the person they believed responsible. Asked whether the bullying and harassment caused distress, 18.3% of the psychiatrists did not report any effect, 30% reported mild distress, 40% moderate distress and severe distress was reported by 11.7%.Conclusions: It was concluded that the magnitude of bullying and harassment among psychiatrists may be quite high, as evidenced by this pilot study. There is a need for extensive systematic studies on this subject and to establish strategies to prevent and address this issue at a national and regulatory level. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.1 (2003) 121-122 [Access article in PDF] Harold Tarrant. Plato's First Interpreters. Ithaca, NY: Cornell University Press, 2000. Pp. viii + 263. Cloth, $55.00. This is Tarrant's third book on the ancient Platonist tradition, following his Scepticism or Platonism? (1985) and Thrasyllan Platonism (1993). In those earlier volumes his focus was on the first centuries bc and ad. Here his scope is much (...) wider. Stating that "Platonic interpretation is today at a crossroads," he has written a book that explores "ancient attempts to wrestle with this corpus," with the ultimate objective "to encourage a fresh, almost primitive reading of Plato himself" (vii).He begins engagingly by confronting the ancients with questions any modern reader of Plato must ask: What kind of text is this? Are there doctrines here? Where do I look for Plato's doctrines? The second part of his book is a historical survey, taking us from Plato, the early Academy and Aristotle, through the Hellenistic and early Roman Imperial period, and concluding with the principal Neoplatonist interpreters. In the third and longest part, he focuses on the interpretation of specific dialogues, giving most space to the Gorgias and Theaetetus, but also dealing in particular detail with the Meno, Parmenides, and Philebus. Something is said about every dialogue, but Tarrant writes only briefly about such major works as the Republic and Timaeus. He explains his selectivity (not very convincingly) as due to his wish to "discuss issues of meta-interpretation, with emphasis on the period before Plotinus" (198).Taking his book as a whole, one realizes that few strands of modern interpretation were not prefigured to quite a large extent in antiquity. The two most obvious exceptions are the chronological and developmental approach (Early, Middle, and Late), at present under strong attack from some quarters, and the theological, numerological, and allegorical readings practiced by Neoplatonists. Plato's ancient interpreters were doctrinal unitarians, but they implicitly anticipated our tendency to distinguish "Socratic dialogues," which some of them called "gymnastic" and "inquisitive," from such "canonical" works as the Phaedo,Republic, Symposium, and Timaeus, to which they applied the labels "dogmatic" and "expository." And they recognized that both types of characteristics could be found in the same dialogue, as in the Meno and Theaetetus. Plato himself, they proposed, spoke primarily through the voices of Socrates, Timaeus, and the Eleatic and Athenian strangers; but other characters, such as Pausanias in the Symposium, or Protagoras in the dialogue of that name, utter thoughts with some philosophical value. In explaining difficult passages of one dialogue, they would typically refer to passages from other parts of the corpus. An especially intriguing instance is the strategy of the Anonymous Commentator on the Theaetetus, who reads the Meno into the dialogue on which he is officially commenting.Ancient scholars, just like ourselves, asked questions about the unifying themes of complex dialogues. Hence the sub-titles given to certain works: "On the soul" for the Phaedo, and "On justice" for the Republic, etc. For Olympiodorus (whose commentary on the Gorgias Tarrant has recently co-edited [Leiden, 1998]), earlier interpreters have seriously erred by giving too limited an account of that dialogue's scope. It is not, he says, simply about rhetoric, nor about justice and injustice; nor is its theme the divine demiurge (as some Neoplatonists had strangely proposed, on the basis of the concluding myth). Rather, the subject of the Gorgias is "the ethical principles that lead to constitutional well-being" (125). [End Page 121] However, Olympiodorus's eminently "sensible" reading (as Tarrant calls it) is deeply embedded in the Neoplatonic contrast between the "purificatory virtues" of the Phaedo and the "constitutional virtues" of Republic4.Strong or weak scepticism, esotericism, unwritten doctrines, spurious versus genuine, a canon of central dialogues, dramatic considerations, and the philosophical importance or non-importance of the dialogues' prologues—all of these are interpretive approaches that Tarrant surveys in this immensely learned book, and all of them continue to resonate for us. Modern scholars, who emphasize the literary and philosophical unity of each dialogue, are walking... (shrink)

The authors also generalize the Crisp Topological Space and Intuitionistic Topological Space to the notion of Neutrosophic Crisp Topological Space. At the end, they present applications to Neutrosophic Database, and show a security scheme based on Public Key Infrastructure (PKI) using Neutrosophic Logic Manipulation. The authors utilize neutrosophic sets in order to analyze social networks data conducted through learning activities, and for the Geographical Information Systems (GIS) they employ fundamental concepts and properties of a Neutrosophic Spatial Region.

Since the world is full of indeterminacy, the Neutrosophics found their place into contemporary research. We now introduce for the first time the notions of Neutrosophic Crisp Sets and Neutrosophic Topology on Crisp Sets. We develop the 2012 notion of Neutrosophic Topological Spaces and give many practical examples. Neutrosophic Science means development and applications of Neutrosophic Logic, Set, Measure, Integral, Probability etc., and their applications in any field. It is possible to define the neutrosophic measure and consequently the neutrosophic integral (...) and neutrosophic probability in many ways, because there are various types of indeterminacies, depending on the problem we need to solve. Indeterminacy is different from randomness. Indeterminacy can be caused by physical space, materials and type of construction, by items involved in the space, or by other factors. In 1965 [51], Zadeh generalized the concept of crisp set by introducing the concept of fuzzy set, corresponding to the situation in which there is no precisely defined set;there are increasing applications in various fields, including probability, artificial intelligence, control systems, biology and economics. Thus, developments in abstract mathematics using the idea of fuzzy sets possess sound footing. In accordance, fuzzy topological spaces were introduced by Chang [12] and Lowen [33]. After the development of fuzzy sets, much attention has been paid to the generalization of basic concepts of classical topology to fuzzy sets and accordingly developing a theory of fuzzy topology [1-58]. In 1983, the intuitionistic fuzzy set was introduced by K. Atanassov [55, 56, 57] as a generalization of the fuzzy set, beyond the degree of membership and the degree of non-membership of each element. In 1999 and 2002, Smarandache [71, 72, 73, 74] defined the notion of Neutrosophic Sets, which is a generalization of Zadeh’s fuzzy set and Atanassov's intuitionistic fuzzy set. Some neutrosophic concepts have been investigated by Salama et al. [61-70]. Forwarding the study of neutrosophic sets, this book consists of seven chapters, targeting to:  generalize the previous studies in [1-59], and[91-94] so to define the neutrosopic crisp set and neutrosophic set concepts;  discuss their main properties; A. A. Salama & Florentin Smarandache  introduce and study some concepts of neutrosophic crisp and neutrosophic topological spaces and deduce their properties;  deduce many types of functions and give the relationships between different neutrosophic topological spaces, which helps to build new properties of neutrosophic topological spaces;  stress once more the importance of Neutrosophic Ideal as a nontrivial extension of neutrosophic set and neutrosophic logic [71, 72, 73, 74];  propose applications on computer sciences by using neutrosophic sets.

This paper studies, by way of an example, the intuitionistic propositional connective * defined in the language of second order propositional logic by * ≡ ∃Q. In full topological models * is not generally definable but over Cantor-space and the reals it can be classically shown that *↔ ⅂⅂P; on the other hand, this is false constructively, i.e. a contradiction with Church's thesis is obtained. This is comparable with some well-known results on the completeness of intuitionistic first-order predicate logic. Over (...) [0, 1], the operator * is undefinable. We show how to recast this argument in terms of intuitive intuitionistic validity in some parameter. The undefinability argument essentially uses the connectedness of [0, 1]; most of the work of recasting consists in the choice of a suitable intuitionistically meaningful parameter, so as to imitate the effect of connectedness. Parameters of the required kind can be obtained as so-called projections of lawless sequences. (shrink)

In this paper we introduce the notion of filter on the neutrosophic crisp set, then we consider a generalization of the filter’s studies. Afterwards, we present the important neutrosophic crisp filters. We also study several relations between different neutrosophic crisp filters and neutrosophic topologies. Possible applications to database systems are touched upon.

Investigation of the 4 th order dynamic systems characteristic polynomials behavior in conditions of the interval parametric uncertainties is carried out on the basis of root locus portraits. The roots behavior regularities and corresponding diagrams for the root locus parameter distribution along the asymptotic stability bound are specified for the root locus portraits of the systems. On this basis the stability conditions are derived, graphic-analytical method is worked out for calculating intervals of variation for the polynomial family parameters ensuring its (...) robust stability. The discovered regularities of the system root locus portrait behavior allow to extract hurwitz sub-families from the non-hurwitz families of interval polynomials and to determine whether there exists at least one stable polynomial in the unstable polynomial family.
