There are two kinds of view in the literature concerning the relevance of intention to permissibility. While subjectivism assumes that an agent acts permissibly if he or she believes that the conduct is necessary for a moral purpose, for objectivism the de facto presence of an objective reason to justify one’s deeds is what matters. Recently, Scanlon and Hanser defend a moderate version of objectivism and subjectivism, respectively. Although I have a degree of sympathy toward both views, I will argue (...) that the truth lies somewhere in between. The view that I suggest in this paper hopefully occupies a space between subjectivism and objectivism and can accommodate the intuitions that neither of those views cannot account for. (shrink)

This study was conducted purposely to assess the degree of school effectiveness among public secondary schools of Zamfara State, Nigeria. In order to achieve this fundamental objective, one research question was formulated. A descriptive survey research design was adopted in the study. Population of the study comprised the entire 2361 classroom teachers deployed in the 158 public secondary schools of Zamfara State-Nigeria. From the population of the study, a sample size of 266 teachers was extracted using a ‘Multistage Random Sampling (...) Technique’. A semi-structured questionnaire developed by Lezzote and Snyder (2011) on a five Likert type scale instrument with 21 items was employed as an instrument for data collection. The instrument composite reliability was computed using Cronbach’s alpha method and obtained the value of .949. All data covered in the study were collected through a field survey approach. Analytically, the current study discovered that, the degree of school effectiveness was at a high extent with mean score (M=3.68, SD=0.15). Based on this finding, the paper recommends that, stakeholders in educational sector comprising government’s ministries, departments and agencies, policymakers, secondary schools’ principals, instructional teachers as well as the learners and their parents/guardians should reciprocally work together in the process of appropriate perpetration and advancement of effective school system and its practices.

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

With a diverse sample (N = 231 paired responses) of employees from various organizations in Pakistan, the authors tested for the main effects of perceived organizational politics and psychological capital on turnover intentions, job satisfaction, and supervisor-rated job performance. They also examined the moderating influence of psychological capital in the politics–outcomes relationships. Results provided good support for the proposed hypotheses. While perceived organizational politics was associated with all outcomes, psychological capital had a significant relationship with job satisfaction and supervisor-rated performance (...) only. As hypothesized, the negative relationship of perceived organizational politics with job satisfaction and supervisor-rated performance was weaker when psychological capital was high. However, the result for turnover intentions was counter to expectations where the politics–turnover intention relationship was stronger when psychological capital was high. (shrink)

We respond to some of the points made by Bennet and Blanck (2022) concerning a previous publication of ours (2021).

Schelling's philosophy can be seen as perpetrating the philosophical fallacy known as the Myth of the Given, in that it takes rational activity to be affected by an experience which is not conceptually mediated. This is supported by Schelling's repeated claim that there is an experience which is indescribable, and which forces us to silence. In the first part of the paper it will be shown how different readings of Schelling result in this fallacy. In the second and third parts (...) an alternative reading will be developed which avoids the fallacy while still making room for unsayable experience. Finally, the proposed interpretation will enable us to interpret Schelling's claim that expressing the unsayable, conveying it to another, is possible after all. »The wish for intelligibility is a terrible one. It means that we are willing to reveal ourselves through the self 's betrayal of itself.« (Stanley Cavell, The World Viewed. (shrink)

The dissemination of information in times of crisis or emergency is distinctive since the affected individuals may take, process, and act on information differently. As the Centers for Disease Control and Prevention noted “the right message at the right time from the right person can save lives.” This study elaborates on the principles of crisis and emergency risk communication (CERC) in the realistic narrative, and notes that a successful CERC should be prompt, accurate, veracious, empathetic, respectful, and promote meaningful action. (...) Since pandemics are not only biomedical but also social, political, economic, and cultural incidents, critical communication in the time of a pandemic is of crucial significance. Hence, the Coronavirus (COVID-19) pandemic is assessed as a recent and important case study. This pandemic had four chief challenges; including that since the disease is caused by the novel SARS-CoV-2 virus the assumptions about the disease have been revised numerously and rapidly. In addition, the cumulative scale and scope of COVID-19 which is in excess of 627 million confirmed cases, and approximately 6.58 million deaths worldwide remained a strain. Another concern was the overwhelming uncertainty and evolving trajectory of the pandemic about how and when it ends or enters the endemic stage of the outbreak. Finally, the overabundance of amplification and dissemination of both accurate and inaccurate information led to an infodemic. Long before the COVID-19 pandemic, many individuals used the internet as an important resource for seeking health-related information. However, the infodemic and the other aforementioned challenges made distinguishing up-to-date accurate information a more arduous task, and CERC and pandemic-related communication are even more crucial. Hence, a multi-dimensional set of skills is required to overcome these challenges whether amidst or after the pandemic. Therefore, a multi-stakeholder approach towards an overarching and comprehensive metaliteracy that “provides an integrated and inclusive framework to cultivate critical thinking and proficiency in comprehending data, information, visuals and the media” is essential. This study recommends and elaborates on how to incorporate metaliteracy into crisis and risk communication at governmental, organizational, and individual levels. (shrink)

Moral realism faces two worries: How can we have knowledge of moral norms if they are independent of us, and why should we care about them if they are independent of rational activities they govern? Kantian constitutivism tackles both worries simultaneously by claiming that practical norms are constitutive principles of practical reason. In particular, on Stephen Engstrom’s account, willing involves making a practical judgment. To will well, and thus to have practical knowledge (i.e., knowledge of what is good), the content (...) of one’s will needs to conform to the formal presuppositions of practical knowledge. Practical norms are thus constitutive of practical knowledge. However, I will argue that the universality principles from which Engstrom derives the formal presuppositions of practical knowledge are reflectively and psychologically unavailable. As a result, they cannot help Kantian constitutivism provide an answer to moral realism's worries. (shrink)

By formalizing some classical facts about provably total functions of intuitionistic primitive recursive arithmetic (iPRA), we prove that the set of decidable formulas of iPRA and of iΣ1+ (intuitionistic Σ1-induction in the language of PRA) coincides with the set of its provably ∆1-formulas and coincides with the set of its provably atomic formulas. By the same methods, we shall give another proof of a theorem of Marković and De Jongh: the decidable formulas of HA are its provably ∆1-formulas.

We take an argument of Gödel's from his ground‐breaking 1931 paper, generalize it, and examine its validity. The argument in question is this: "the sentence G says about itself that it is not provable, and G is indeed not provable; therefore, G is true".

This article considers the traditional Islamic narrative in the light of the theory of religion espoused by John Hick (1922–2012). We see how the Islamic narrative changes on a Hickean understanding of religion, particularly in the light of the ‘bottom-up’ approach and trans-personal conception of the religious ultimate that it espouses. Where the two readings of Islam appear to conflict, I suggest how they can be reconciled. I argue that if Hick’s theory is incompatible with Islamic belief, then this incompatibility (...) does not manifest itself at the level of belief in the narrative. (shrink)

Even those who consider themselves lucky to have escaped trauma, long-term illness and death, have experienced radical changes to their conception of life in its relation to public and private domains due to the COVID-19 pandemic. When public space turned into a dangerous realm, private interiors were assigned a new role and with these shifts, also new questions about the relation of interiority to any type of exteriority emerged. The first four contributions in this ‘Projected Interiorities’ issue of Technoetic Arts (...) (TA) reflect from an architectural and urban point of view on the conception of the public and private, their past, present and future. Yet, the pandemic contributed more widely to a re-evaluation of interiority, not least because the public and private realms seemingly coalesced via digital processes. While this journal issue cannot cover all these questions, it indicates the range of the pandemic turn in thought, collecting contributions from theory and practice, including architecture, art, philosophy and literary studies. With authors of a variety of disciplinary backgrounds based in China, India, Norway, France, the United Kingdom and the United States, this issue of TA covers not only a multiplicity of methodological approaches but also diverse regional and cultural perspectives on the idea of ‘Projected Interiorities’.

Digitalization and the emergence of the Internet have resulted in escalating access to information and communication. Given the circumstances that soaring access to information amounts to the intensification of misinformation and disinformation, a set of critical skills to navigate and critically assess the information is necessary. This paper outlines the significance of these skills, and provides a perspective on metaliteracy as a supplement to media and information literacy, and argues that the ability to conceptualize, access, comprehend, analyze, and use information (...) is crucial in achieving inclusive, pluralistic, and participatory knowledge societies.

We demonstrate that, in itself and in the absence of extra premises, the following argument scheme is fallacious: The sentence A says about itself that it has a property F, and A does in fact have the property F; therefore A is true. We then examine an argument of this form in the informal introduction of Gödel’s classic (1931) and examine some auxiliary premises which might have been at work in that context. Philosophically significant as it may be, that particular (...) informal argument plays no rôle in Gödel’s technical results. Going deeper into the issue and investigating truth conditions of Gödelian sentences (i.e., those sentences which are provably equivalent to their own unprovability) will provide us with insights regarding the philosophical debate on the truth of Gödelian sentences of systems—a debate which goes back to Dummett (1963).

This article argues that businesses are morally responsible for compensating the people harmed by their activities even if they were not negligent, i.e., the businesses took reasonable precautions. Critics of this position maintain that responsibility requires choice, and by taking precautions, businesses choose not to harm others. This article accepts their argument’s first premise but rejects the second premise. It contends that businesses often seek risky or innovative activities to increase profits, and the essence of innovative activities is that precautions (...) cannot sufficiently reduce their foreseeable harmful consequences. The correct understanding of businesses’ decision-making enables us to appreciate that businesses choose to undertake risky activities while knowing that they can harm others despite preventive measures. It follows that preventive measures should not serve as an excuse against liability for harm. (shrink)

Using a time-lagged design, we tested the main effects of Islamic Work Ethic (IWE) and perceived organizational justice on turnover intentions, job satisfaction, and job involvement. We also investigated the moderating influence of IWE in justice–outcomes relationship. Analyses using data collected from 182 employees revealed that IWE was positively related to satisfaction and involvement and negatively related to turnover intentions. Distributive fairness was negatively related to turnover intentions, whereas procedural justice was positively related to satisfaction. In addition, procedural justice was (...) positively related to involvement and satisfaction for individuals high on IWE however it was negatively related to both outcomes for individuals low on IWE. For low IWE, procedural justice was positively related to turnover intentions, however it was negatively related to turnover intentions for high IWE. In contrast, distributive justice was negatively related to turnover intentions for low IWE and it was positively related to turnover intentions for high IWE. (shrink)

Interesting as they are by themselves in philosophy and mathematics, paradoxes can be made even more fascinating when turned into proofs and theorems. For example, Russell’s paradox, which overthrew Frege’s logical edifice, is now a classical theorem in set theory, to the effect that no set contains all sets. Paradoxes can be used in proofs of some other theorems—thus Liar’s paradox has been used in the classical proof of Tarski’s theorem on the undefinability of truth in sufficiently rich languages. This (...) paradox (as well as Richard’s paradox) appears implicitly in Gödel’s proof of his celebrated first incompleteness theorem. In this paper, we study Yablo’s paradox from the viewpoint of first- and second-order logics. We prove that a formalization of Yablo’s paradox (which is second order in nature) is non-first-orderizable in the sense of George Boolos (1984). (shrink)

This essay delves into the multifaceted concept of determin-ism within the domain of physics, scrutinizing prevalent definitions and classifications. Navigating through the nuances of deterministic behavior, we distinguish it from colloquial interpretations of "non-deterministic." By examining determin-ism through the lenses of natural laws, weak determinism, and strong determinism, we unravel the intricate relationship between predictability and the underlying mathematical structures of the universe. Classical mechanics serves as an exemplar of deterministic principles, while statistical mechanics introduces complexities that challenge simplistic classifications. (...) The interplay between ignorance and non-determinism emerges as a pivotal consideration, urging a nuanced understanding of deter-ministic frameworks amidst intricate systems. In essence, this exploration seeks to reconcile the richness of deterministic behavior with the complexities inherent in the natural world. (shrink)

This study examines the impact of Islamic Work Ethic on organizational citizenship behaviors and knowledge-sharing behaviors among university employees in Pakistan. A total of 215 respondents from public sector educational institutions participated in this research. The findings suggest that IWE has a positive effect on OCBs. In other words, individuals with high IWE demonstrate more citizenship behaviors than those with low IWE. The findings also suggest a positive effect of IWE on KSBs. Individuals with high IWE exhibit more KSBs than (...) those with low IWE. The paper also discusses the theoretical and practical implications of these findings. (shrink)

"All-and-Nought" is the 2nd Edition of a series of books that study the nature of Reality and Being. The first edition of the book, "The Metaphysics of All-and-None", was published by Edwin Mellen Press in January 2022; since then the book has been under severe investigations and reviews by many scholars and pundits worldwide. The 2nd edition of the book contains the original text plus a foreword by Professor Richard Howells from King’s College London and some reports by Physicists, Biologists, (...) and others. Journal of Mind, one the most important journals in Philosophy, paid attention to the book and in its critical review article October 2022, encourages all philosophers and pundits to study the book. -/- The book's core concept is a Scientific/Mathematical, a-priori/synthetic theory called All'n'None Theory. It studies the Symmetry and Asymmetry in Reality and points to a state that indicates the deep Symmetry between "All Beings" and "Nothingness". It deeply studies the relationships between being and non-being from the perspective of Symmetry and symmetry failure and offers a measurement tool and a new method of studding phenomena. -/- It seems All`n`None Theory is a scientific breakthrough and discovery. The book methodologically applies Physics, Conceptual philosophy, Mathematics, and jurisprudence analysis both inductively and deductively to prove its theory. It is the first and the only Theory for Explaining the nature of Existence (being) and provides a technique to measure the amount of existence in each being. -/- Through understanding Existence, the book explains Creation, Cosmos, Consciousness, Mind, Spirit, and Soul scientifically. It is deep enough to initially encompass and then merge all modern Sciences (Physics, Philosophy, Complexity, System Theory, Information Theory, Psychology, Biology, Humanities, Economy, and Management) with Buddhism, Hinduism, Judaism, Christianity, and Islam (Theology) and makes the image of Reality clearer for readers. -/- The book proves chaos management in the depth of creation and shows how people can use the only law of creation for their own success and salvation. Therefore the book is an inspirational one too. Readers by reading the book and understanding it not only gain scientific knowledge but also find profound wisdom that heals them. They feel they are enlightened and motivated to construct their meaning of life. Readers can recognize their self/ego structure of being and enjoy the passion to improve. -/- The book tries to explain the mechanism of Thinking with respect to Symmetry and the failure of Symmetry as the foundation of Categorization, Mentalization, and Cognition. By understanding the mechanism of cognition it can study Epistemology and explain the Believing Mechanism and the nature of Beliefs as a kind of being. The theory claims no matter the beliefs originated from Science or Religion the mechanisms that govern both of them are the same. Based on the theory, “Knower or Observer”, “Known or Observed”, and “knowing or observation” are rooted in Symmetry and its failure. The tone, language, and structure of the book are unique to itself. It is not an entertainment or commercial book. The book is written for readers who plan to spend enough time to think about its content. (shrink)

All’n’None theory is the subject of a book titled “The Metaphysics of All-and-None a Synthesis of Science, Philosophy, and Religion” published by Edwin Mellen Press on Jan 2022 [1].

Several independent blind reviews by different organizations and scholars on the book indicate that the theory is not only a new development in philosophy but also is a scientific theory with the capacity for experimental verification. All (...) the reviews encourage Philosophers and Scientists to step in, comprehend it, and further investigate the theory. Among all the reviews the most important one was done by Oxford Academics, They published a critical review on Mind Journal October 2022 confirming [2] All’n’None is a scientific platform for deeper understanding of Reality and its full capacity has not been discovered yet.

Kripke frames (and models) provide a suitable semantics for sub-classical logics; for example, intuitionistic logic (of Brouwer and Heyting) axiomatizes the reflexive and transitive Kripke frames (with persistent satisfaction relations), and the basic logic (of Visser) axiomatizes transitive Kripke frames (with persistent satisfaction relations). Here, we investigate whether Kripke frames/models could provide a semantics for fuzzy logics. For each axiom of the basic fuzzy logic, necessary and sufficient conditions are sought for Kripke frames/models which satisfy them. It turns out that (...) the only fuzzy logics (logics containing the basic fuzzy logic) which are sound and complete with respect to a class of Kripke frames/models are the extensions of the Gödel logic (or the super-intuitionistic logic of Dummett); indeed this logic is sound and strongly complete with respect to reflexive, transitive and connected (linear) Kripke frames (with persistent satisfaction relations). This provides a semantic characterization for the Gödel logic among (propositional) fuzzy logics. (shrink)

YouTube has been implicated in the transformation of users into extremists and conspiracy theorists. The alleged mechanism for this radicalizing process is YouTube’s recommender system, which is optimized to amplify and promote clips that users are likely to watch through to the end. YouTube optimizes for watch-through for economic reasons: people who watch a video through to the end are likely to then watch the next recommended video as well, which means that more advertisements can be served to them. This (...) is a seemingly innocuous design choice, but it has a troubling side-effect. Critics of YouTube have alleged that the recommender system tends to recommend extremist content and conspiracy theories, as such videos are especially likely to capture and keep users’ attention. To date, the problem of radicalization via the YouTube recommender system has been a matter of speculation. The current study represents the first systematic, pre-registered attempt to establish whether and to what extent the recommender system tends to promote such content. We begin by contextualizing our study in the framework of technological seduction. Next, we explain our methodology. After that, we present our results, which are consistent with the radicalization hypothesis. Finally, we discuss our findings, as well as directions for future research and recommendations for users, industry, and policy-makers. (shrink)

I will argue that Avicenna’s and Aquinas’s faith-based virtue ethics are crucially different from Aristotle’s virtue ethics, in that their ethics hinges on the theological notion of heaven, which is constitutively independent of the ethical life of the agent. As a result, their faith-based virtue ethics is objectionable. Moreover, I will also argue that the notion of heaven that Avicenna and Aquinas deploy in their moral philosophy is problematic; for it can rationally permit believers to commit morally horrendous actions. Finally, (...) I will present a Kantian notion of heaven which is immune to the aforementioned moral objection. The Kantian notion of heaven, nevertheless, cannot ground any view of ethics as it is constitutively dependent on the ethical life of the agent. (shrink)

We investigated the impact of psychological capital (PsyCap) on supervisory-rated innovative performance and job stress. Data collected from a diverse sample (N = 237 paired responses) of employees from various organizations in Pakistan provided good support for the hypotheses. The results indicate that PsyCap is positively related to innovative job performance and negatively related to job stress. High PsyCap individuals were rated as exhibiting more innovative behaviours by their supervisors than low PsyCap individuals. Particularly, we found that high PsyCap individuals (...) were more likely to generate, acquire support for, and implement novel ideas in their workplace. Similarly, individuals with high PsyCap reported lower levels of job stress as compared to their low PsyCap counterparts. (shrink)

A disagreement between two philosophers, William Alston and J. L. Schellenberg, on the matter of religious commitment serves to exemplify an important difference between religious believers and religious sceptics. The disagreement occurs in the context of a discussion over the plausibility of Alston’s doxastic practice approach as applied to religious belief. I argue that a close reading of Alston and Schellenberg shows that they do not, despite what they may think, differ greatly from each other. I conclude by drawing some (...) lessons for interreligious dialogue, particularly that the focus of engagement should not necessarily be to convince but rather to uncover differences in attitude.

We present a new justification for methodological triangulation (MT), the practice of using different methods to support the same scientific claim. Unlike existing accounts, our account captures cases in which the different methods in question are associated with, and rely on, incommensurable theories.

We argue that, under the usual assumptions for sufficiently strong arithmetical theories that are subject to Gödel’s First Incompleteness Theorem, one cannot, without impropriety, talk about *the* Gödel sentence of the theory. The reason is that, without violating the requirements of Gödel’s theorem, there could be a true sentence and a false one each of which is provably equivalent to its own unprovability in the theory if the theory is unsound.

Throughout history, Eurasia has been central to relations between Europe and Asia. It has been the crossroads of civilizations, contributing to the cultural and ethnic hybridity of the region. However, after the fall of the Ottoman Empire and later the Soviet Union in the twentieth century, Eurasia lost its geostrategic importance in the US-led liberal world order. In the 1920s, a group of Russian emigres described the cultural and ethnic ties among the communities living across the vast Eurasian steppes as (...) Eurasianism. Eurasianists divide the world into two opposing forces with Eurasianism including Russia and the European states favoring integration with it and Atlanticism including the US and European countries supporting an American-led Atlantic order. Today, Russia is an important revisionist power in Eurasia, with huge stakes in the global order and the capability to help forge new relationships in the region. (shrink)

In this novel work, Paul Chilton expends a considerable amount of effort examining relations between the use of language and political discourse. Many realist linguists in the past century claimed that language should be evaluated as the innate part of a human mind.

Since the disintegration of the USSR Eurasia has gained a new geopolitical and strategic significance. Fifteen Countries emerged as a result of disintegration, among which only the Russian Federation was the successor state. The post-soviet era especially the era of the 1990s was a political and economic trauma for the Russian Federation and the post-soviet space. But Eurasianists were well aware of the American unilateralism and American ‘Grand Chessboard strategy” that was solely aimed at encircling Russian geography. With these concerns, (...) the Eurasianists advised the Russian political and military elites to initiate the Eurasian Union Project. This paper briefly sketches the Russian historical Eurasian dream, which deeply rooted in Russian imperial history, and discusses the importance of Eurasian philosophy for the political and economic stability of Russia-Eurasia. The paper also illustrates the challenges and opportunities for Eurasian integration and for the establishment of multipolar world order. Moreover, the paper also briefly outlines the geopolitical rationale behind the Eurasian project as a key objective of contemporary Russian foreign policy and geopolitics. (shrink)

Intuitionistic Propositional Logic is proved to be an infinitely many valued logic by Gödel (Kurt Gödel collected works (Volume I) Publications 1929–1936, Oxford University Press, pp 222–225, 1932), and it is proved by Jaśkowski (Actes du Congrés International de Philosophie Scientifique, VI. Philosophie des Mathématiques, Actualités Scientifiques et Industrielles 393:58–61, 1936) to be a countably many valued logic. In this paper, we provide alternative proofs for these theorems by using models of Kripke (J Symbol Logic 24(1):1–14, 1959). Gödel’s proof gave (...) rise to an intermediate propositional logic (between intuitionistic and classical), that is known nowadays as Gödel or the Gödel-Dummett Logic, and is studied by fuzzy logicians as well. We also provide some results on the inter-definability of propositional connectives in this logic. (shrink)

It is quite well-known from Kurt G¨odel’s (1931) ground-breaking Incompleteness Theorem that rudimentary relations (i.e., those definable by bounded formulae) are primitive recursive, and that primitive recursive functions are representable in sufficiently strong arithmetical theories. It is also known, though perhaps not as well-known as the former one, that some primitive recursive relations are not rudimentary. We present a simple and elementary proof of this fact in the first part of the paper. In the second part, we review some possible (...) notions of representability of functions studied in the literature, and give a new proof of the equivalence of the weak representability with the (strong) representability of functions in sufficiently strong arithmetical theories.

‎A universal schema for diagonalization was popularized by N. S‎. ‎Yanofsky (2003)‎, ‎based on a pioneering work of F.W‎. ‎Lawvere (1969)‎, ‎in which the existence of a (diagonolized-out and contradictory) object implies the existence of a fixed-point for a certain function‎. ‎It was shown that many self-referential paradoxes and diagonally proved theorems can fit in that schema‎. ‎Here‎, ‎we fit more theorems in the universal‎ ‎schema of diagonalization‎, ‎such as Euclid's proof for the infinitude of the primes and new proofs (...) of G.

Owing to the escalating regional rivalries and the conventional arms race, Iran’s post-revolutionary hostilities towards the West, in addition to the crucial geopolitical and economic significance of the region, the complex Iranian nuclear crisis has made the global leaders to brood over the multilateral Iranian negotiations with the P5+1 and the International Atomic Energy Agency, which led to finalization and adoption of the Joint Comprehensive Plan of Action in 2015. The United Kingdom as a permanent member of the United Nations (...) Security Council, a nuclear state, the bridge to the Cross-Atlantic relations, in addition to its noted ‘special relationship’ with the United States, and having over two centuries of political ties with Iran has constantly played a crucial role in all stages of the negotiations and tightening the imposed embargoes. Indeed, ever since the 1979 Revolution the Anglo-Iranian relations have been volatile and have suffered from tension, instability, and upheavals; despite reconciliation in 1998 and some prominent diplomatic accomplishments in nuclear negotiations the sour relations had strained by several incidents in the past two decades. This study addresses the Anglo-Iranian relations and attempts to provide theoretical scrutiny of the UK foreign policy on the Iranian nuclear program and clarify the British approach through the lens of game theories with respect to neorealism, classical realism, neoclassical realism, and liberalism perspectives.

The phenomena of terrorism and other politically motivated violence have been assessed across different disciplines from political science and economics to theology and psychology. Whereas the definitions of the concepts of “terrorism” and “terrorist” are disputed and they rather reflect the perspectives of the defining entity, there is a common consensus that terrorism can be classified in terms of its type (such as state-sponsored, dissent, religious, pathological, narco-, cyber-, and bioterrorism), the scale (i.e. domestic vs. international), motives, and objectives. By (...) the same token, the roots and causes of terrorism can be enumerated as internal sources (such as social, economic, political, and cultural indicators) and external sources (such as colonialism and neocolonialism, regional conflicts and historical enmities, failed/failing states and lawless areas, and the penetration of foreign cultures and lifestyles). Although such grounds can be considered as the collective causes, they can merely address how one becomes a potential appropriate recruit for terrorist organizations. Hence, identifying the causes of terrorism is of paramount significance in order to both combat and most importantly prevent terrorism. Given that the first generation of psychological approaches to terrorist violence, chiefly drawing from psychoanalytic theory, has basically run its course, this study takes a systematic approach to evaluate the root causes of terrorism, particularly from social and behavioral perspectives, and attempts to address some key questions such as the progress of and reasons for individuals supporting, joining and leaving terrorist organizations, the relevance of psychopathology to comprehending and preventing terrorism, and the roles of ideology, identity, and belonging in terrorist behavior.

From the animosity of the Cold War era, the rapprochement in 1972, normalization of relations in 1979, to rising China and the current trade war, the US-China relationship has emerged and been regarded as an important relationship in global politics, and distinctively significant in the shaping of world order. The United States, a fount of modern think tanks, is home to approximately 30% of the total in the world. These think tanks were gradually embedded into American politics and exercise undoubtedly (...) significant influence in the policymaking process, particularly foreign affairs. Hence, as an emerging global power, China has been the subject of US think tanks debate from different perspectives, such as economy, military, and foreign affairs. This study reviews the post-World War II US-China relations, addresses China’s economic and military rise, its territorial claims and provides policy options for balancing cooperation and conflict in each of these matters. Given that the assimilation of perspectives of American think tanks can foster comprehending the perception of the US regarding China’s rise and Washington-Beijing relations, this internet-mediated research based on foreign policy analysis with the principal focus on agency at institutional level takes a systematic approach to discuss China policy debates among the US think tanks. The objective is to offer an overall review of the China policy debate in the US over the past two decades, whereas the chief focus is dedicated to the perceptions of China in American think tanks about the concepts of “China collapse”, “China threat” and “China responsibilities”; furthermore, providing an assessment of the impact of think tanks on China’s most-favored-nation (MFN) treatment, the legislature on permanent normal trade relations (PNTR), and contemporary trade relations between the two countries.

پژوهشگران پدیده تروریسم را از مواضع مختلفی ازجمله سیاسی، اقتصادی، روانشناختی، اجتماعی، فرهنگی و دینی مورد مطالعه قرار دادهاند. علیرغم وجود تعاریف متعدد و غیرواحدی از مفهوم تروریسم و تروریست بیان شده است که به طور کلی بیانگر دیدگاه ارائه دهنده آن است، اجماعی بر دسته بندی تروریسم یراساس نوع (مانند دولتی، مذهبی، پاتولوژیک، سایبری، نارکوتروریسم و بیوتروریسم)، مقیاس (داخلی و بین المللی)، انگیزه ها و اهداف آن وجود دارد. همچنین، ریشه ها و علل تروریسم می تواند منشا داخلی (مانند (...) شاخص های اجتماعی، اقتصادی، سیاسی و فرهنگی) و خارجی (مانند استعمار و پسااستعمار، درگیری های منطقه ای و دشمنی های تاریخی، دولت درمانده و مناطق بی قانون، و نفوذ فرهنگ و سبک زندگی بیگانه) داشته باشد. چنین زمینه هایی می توانند به عنوان علل اشتراکی در نظر گرفته شوند و صرفا بیانگر دلایل احتمالی تبدیل یک فرد به یک عضو بالقوه سازمانهای تروریستی است ولی بهندرت توضیحی درباره چگونگی جذب آن فرد به سازمان های تروریستی ارائه می کنند. از این رو، شناسایی علل ظهور تروریسم و عضویت افراد در سازمانهای تروریستی از اهمیت ویژهای به منظور مبارزه و جلوگیری از آن برخوردار است. با توجه به اینکه نسل اول رویکردهای روانشناختی به خشونت تروریستی اساسا از تئوری روانکاوی نشئت می گرفتند و دیگر توجیه کننده تروریسم مدرن نیستند، این پژوهش با رویکردی سیستماتیک مبنی بر روش پدیدارشناسی به ارزیابی دلایل اصلی تروریسم بهویژه از منظر اجتماعی و رفتاری می پردازد. هدف این پژوهش مطرح کردن و پاسخ دادن به سوالات کلیدی شامل دلایل افراد برای حمایت، عضویت، و ترک سازمان های تروریستی، مناسب بودن علم آسیب شناسی روانی برای درک و جلوگیری از تروریسم، و نقش ایدئولوژی، هویت و تعلق در رفتار تروریستی است.

Issues including the immigration flows, increased diversity of the society, and alienation of parts of the population are not necessarily new phenomena for the European Union. As an illustration, Frontex, the EU Agency for the Management of Operational Cooperation at the External Borders, was founded in 2004 in the light of the uncontrolled immigration from Africa to control the cooperation between national border guards securing its external borders, or EUROSUR (the European Border Surveillance System) has come to effect since 2013.

In this paper comparative analysis of maximum power point tracking techniques has been conducted to achieve highest magnitude of power from photovoltaic array. The algorithms proposed in this paper for extracting peak output from photovoltaic array are Perturb and Observe, Incremental Conductance, and Fuzzy Logic Control. There are some limitations with conventional converters i.e. Buck-Boost converter. When the operating voltage exceeds normal voltage as the voltage becomes high, the conventional converters fail to carry high voltage and current. Apart from this (...) the ripple contents also increase abnormally due to the large impedance in the conventional converter. Similarly these converters cannot track maximum power point faster and effectively. In that case Single Ended Primary Inductor Converter (SEPIC) is the best choice instead of the conventional buck-boost converter, which is employed with the aim of extracting maximum output from the photovoltaic array. The aim of this study is to compare three MPPT techniques under varying environmental conditions with respect to maximum power extraction and speed of tracking time. SEPIC is used instead of conventional buck-boost converter in order to achieve maximum efficiency and less ripples. Also it can track maximum power point (MPP) faster than Buck-Boost Converter. Comparative analysis of three most extensively used MPPT techniques have been conducted in Simulink/Matlab. (shrink)

The title of the book was chosen due to inspiration from Nietzsche’s famous book ‘Beyond good and Evil’, which has marked an unprecedented turning point in the history of philosophy. Hence, the book titled ‘Beyond Civilization and History’ is intended to outline the politico-historical debate, since the dawn of the 20th century. The discussion in the book will cover pre-modern, modern and post-modern discourse of the history of civilizations. The debate mainly focuses on the modernist and post-modernist historical context especially (...) surrounding the writings of Oswald Spengler, Norman Angell, Arnold J. Toynbee, and Alexander Dugin.

Abstract: The objective of this study was to evaluate water productivity of alfalfa (Medicago sativa) under centre pivot irrigation system. The experimental works were conducted at three centre pivot irrigation projects (Indian, Arab Authority for Agricultural Investment and Development (AAAID) and Sedonix projects) located at Khartoum State during the period from April 2011 to April 2013. In each project, three irrigation systems were randomly selected for the study treatments. Crop water requirement was obtained using CROPWAT 8 computer model. The parameters (...) tested were Christiansen coefficient of uniformity (Cu%), distribution uniformity (Du%), Scheduling uniformity (Su) and Water productivity (kg/m3). SAS (statistical package) was used to analyze the data. The variations among means were checked by the least significant difference (LSD). The results showed that Cu%, Du%, Su and water productivity significantly affected by the management practices in different irrigated projects. Sedonix project gave the highest values of hydraulic characteristic (Cu 85%, Du 81% and Su 1.23) while AAAID project recorded the lowest values (Cu 74%, Du 70%, Su 1.43). Water productivity significantly increased in Sedonix project (0.45 kg/m3/cut) followed by Indian projects (0.38 kg/m3/cut) and AAAID which ranked the least (0.27 kg/m3/cut). It is concluded that for improvement water productivity; proper technical guidelines for system management, operation and scheduling should be followed. (shrink)

In this paper, we first examine the reasons for opposing metaphysics. While assessing these reasons, we intend to reach a plausible stance regarding the relationship between science and metaphysics and its role and importance in scientific activity. There are different views on this old question. We argue that the interaction of metaphysics and science is a complex interaction that can only be defended in the light of a critical approach. In this critical attitude, one should not only pay attention to (...) the role and importance of metaphysics in science but also should have an epistemic humility about his expectations of it.
