Financial risks are among the most important risks in the construction industry projects, which significantly impact project objectives, including project cost. Besides, financial risks have many interactions with each other and project parameters, which must be taken into account to analyze risks correctly. In addition, a source of financial risks in a project is the contract, which is the most important project document. Identifying terms related to financial risks in a contract and considering their effects on the risk management process (...) is an essential issue that has been neglected. Hence, an integrated model for evaluating financial risks and their related contractual clauses were presented. To this end, the effect of financial risks on the project cost was simulated using a system dynamics model. Moreover, terms related to financial risks in a contract text were identified and extracted using text mining, and their effect was included in the system dynamics model. The model was implemented in a hospital construction project in Tehran as a case study, and its results were analyzed. The innovation of the research is integrating text mining and the system dynamics model to investigate the effect of financial risks and related contractual clauses on the project cost. (shrink)

While extensive scholarship has been dedicated to the emotional experiences of transplant patients, little is known about the emotional experiences of transplant co‐ordinators. Semi‐structured face‐to‐face interviews conducted with ten transplant co‐ordinators who have worked for more than 20 years in this job. The transplant co‐ordinators spoke of negative feelings and moral distress with regard to futile care of deceased donor family members as well as of living donors. Transplant co‐ordinators experience intense negative feelings, emotional pain, and moral distress on a (...) daily basis. Transplant co‐ordinators play a pivotal role in the process of obtaining consent for live or dead donation of organ; however, their well‐being and job satisfaction are impaired by contradictions between their moral values and the tasks they are instructed to perform. The study exposes the silent emotional suffering of transplant co‐ordinators; main findings show that the transplant co‐ordinators are torn between contradictory expectations and a gap between values and praxis. It is recommended to offer them training and support for the sake of their retention. (shrink)

This study examines the impact of the level of religious observance on the attitudes toward end‐of‐life (EOL) decisions and euthanasia of Jews in Israel—where euthanasia is illegal—as compared to Jews living in the USA, in the states where euthanasia is legal. A self‐reporting questionnaire on religiosity and personal beliefs and attitudes regarding EOL care and euthanasia was distributed, using a convenience sample of 271 participants from Israel and the USA. Findings show that significant differences were found in attitudes between Jews (...) of different levels of religious observance with respect to patient autonomy, right to die with dignity, and dying in familiar and supportive surroundings. The USA and Israeli Jews have similar knowledge regarding EOL care and expressed similar attitudes and perceptions toward the issues of authority of medical staff and religious figures and patient's autonomy. Findings indicate that the level of religious observance has more potency in shaping their attitudes and perceptions of EOL decisions than the state law. We conclude by discussing the implications of our findings with regard to multicultural health systems and providing practical recommendations. (shrink)

This paper concerns the recent revival of entity realism. Having been started with the work of Ian Hacking, Nancy Cartwright and Ronald Giere, the project of entity realism has recently been developed by Matthias Egg, Markus Eronen, and Bence Nanay. The paper opens a dialogue among these recent views on entity realism and integrates them into a more advanced view. The result is an epistemological criterion for reality: the property-tokens of a certain type may be taken as real insofar as (...) only they can be materially inferred from the evidence obtained in a variety of independent ways of detection.

Having constituted a new epoch in human history and a new religiouspolitical order, the revealed religions challenged the tradition of Greek philosophy to adjust to, investigate, and make intelligible a religiouspolitical order based on prophecy, revelation, and the divine law. The challenge led certain Arab and Muslim philosophers to reassess the relative distance between the thought of the Greek masters, and the doctrines propagated by the revealed religions, and to make use of such works as Plato's Republic and Laws, rather (...) than Aristotle's Politics, when offering a philosophic account of the new religious–political phenomenon and of such new disciplines as the science of the divine law and the science of revealed theology. Les religions révélées, en inaugurant une ère nouvelle dans l'histoire humaine et un nouvel ordre “religio-politique”, ont constitué un défi pour la tradition de la philosophie grecque. Celle-ci devait s'adapter a un ordre religio-politique fondé sur la prophétie, la révélation et la loi divine, en faire un objet d'investigation et le rendre intelligible. Ce défi conduisit certains philosophes arabes et musulmans à réévaluer la distance qui sépare la pensée des maîtres grecs des doctrines propagées par les religions révelées. Il les conduisit aussi à faire usage d'oeuvres telles que la République et les Lois de Platon, plutôt que la Politique d'Aristote dans leur effort de rendre compte philosophiquement du phénomène religio-politique nouveau et des nouvelles disciplines telles que la science de la loi divine et la science de la théologie révélée.

This paper draws on the phenomenological-hermeneutical approaches to philosophy of science to develop realist perspectivism, an integration of experimental realism and perspectivism. Specifically, the paper employs the distinction between “manifestation” and “phenomenon” and it advances the view that the evidence of a real entity is “explorable” in order to argue that instrumentally-mediated robust evidence indicates real entities. Furthermore, it underpins the phenomenological notion of the horizonal nature of scientific observation with perspectivism, so accounting for scientific pluralism even in the cases (...) of inconsistent models. Overall, realist perspectivism is proposed as the way to go for (phenomenologically-hermeneutically minded) philosophers of science. (shrink)

Relying on the notion of “overlapping perspectives,” this paper argues that entity realism and perspectivism are complementary. According to entity realism, it is justified to maintain a positive attitude toward the existence of unobservable entities with which multiple experimental interactions are possible. Perspectivism also explains that our beliefs about these entities are bounded by historically contingent theoretical and instrumental perspectives. The argument of the paper is developed through a discussion of Ronald Giere’s versions of realism: entity realism, constructive realism, and (...) perspectival realism. (shrink)

This study is designed to delve into the issue of culture from the lens of pragmatics as far as the translation of Persian expressions is concerned. To this end, the researchers explored two problematic areas in translation: the first one is a universally challenging element of language, i.e. metaphor, while the other one is an Iranian culture-specific element of language, i.e. Taarof. To uncover the reason behind such difficulty and various techniques to handle such culturally dependent concepts in the act (...) of translation, the researchers sampled a few English subtitles of Iranian films and examined them both qualitatively and quantitatively drawing on the Gricean maxims. The results revealed a high number of infringements both in the translated instances of metaphor and Taarof as far as the maxim of manner, i.e. being perspicuous, is concerned. This highly-frequent flaw in the openness in translation could be mainly attributed to a vast cultural chasm between the source and target language, which makes such culturally-oriented translations a tall order even on the part of the most accomplished translators.

After a brief review of the relationship between science and value, this paper introduces the value of ‘traditionality’ as a value in the pure and applied sciences. Along with other recognized values, this value can also contribute to formulating hypotheses and determining theories. There are three reasons for legitimizing the internal role of this value in science: first, this value can contribute to scientific progress by presenting more diverse hypotheses; second, the value of external consistency in science entails this value; (...) and third, this value helps to eliminate some of the adverse social and cultural effects of Western science in non-Western societies. ‘Traditionality’ is an extrinsic epistemic value, according to the first two reasons, and at the same time, is an ethical value, according to the last reason. Also, the ethics of belief is adopted to further confirm the ethical role of this value. Finally, this paper discusses three potential criticisms that can be levelled against this idea and responds to each of them. (shrink)

Taking a cue from Slavoj Zizek’s reading of the Qur’anic tale of the two sons of Adam, Abel and Cain, this paper examines an overlooked erotic layer of meaning archived in the key Qur’anic term for sacrifice; it also explores the nexus of eroticism and sacrifice in this tale. At the beginning of this text the Qur’an announces that the “truth” of this story will be told. However, that truth turns out to be the symbolic absence of the truth, allowing (...) for a range of interpretive possibilities. I will argue that in the Qur’anic narrative of Cain and Abel the “shame/penis” of the murdered brother is the site of the archive, and interpretive possibilities are conditioned by the function of the master-signifier, the phallus alluded to in the text by the presence of the penis.

This paper will offer a systematic reconstruction of al-Ġazālī’s Sceptical Argument in his celebrated Deliverer/Delivered from Going Astray (al-Munqiḏ/al-Munqaḏ min al-Ḍalāl). Based on textual evidence, I will argue that the concept of certainty (yaqīn) in play in this argument is that of the philosophers—most notably Ibn Sīnā—and that it is firmly tied to demonstration (burhān) and hence to the materials of syllogism (mawwād al-qiyās). This will show that contrary to what many scholars believe, this Sceptical Argument is al-Ġazālī’s discovery of (...) a latent sceptical problem in Muslim philosophers’ epistemological theories based on Aristotle’s Posterior Analytics that escaped even the agile mind of aš-šayḫ ar-raʾīs Ibn Sīnā. This reconstruction will also shed some light on the widespread assumption that al-Ġazālī anticipates Descartes’s sceptical considerations in the First Meditation. I will argue that not only do the two thinkers use incompatible strategies to reach their respective sceptical conclusions, but both their conclusions and their use of God in refuting them are also essentially non-identical. The conclusion is that the two sceptical arguments are essentially different. (shrink)

Transplant coordinators play a pivotal role in the process of obtaining consent for live or dead donation of organs. The objective of the project is to unveil emotional experiences and ethical conduct of transplant coordinators using a qualitative research methodology. Ten transplant coordinators who have worked for more than 20 years in this job were recruited by using a purposive sampling technique. The transplant coordinators spoke of negative feelings and moral distress with regard to futile care of family members of (...) deceased donors as well as of living donors. Transplant coordinators experience moral distress on a daily basis; being compelled to compromise their integrity causes moral distress and moral residue, hence, training and support should be offered to them.

The special theory of relativity holds significant interest for scientific perspectivists. In this paper, I distinguish between two related meanings of “perspectival,” and argue that reference frames are perspectives, provided that perspectival means “being conditional” rather than “being partial.” Frame-dependent properties such as length, time duration, and simultaneity, are not partially measured in a reference frame, but their measurements are conditional on the choice of frame. I also discuss whether the constancy of the speed of light depends on perspectival factors (...) such as the idealized definition of the speed of light in a perfect vacuum and the Einstein synchronization convention. Furthermore, I argue for the view that the constancy of its speed is a robust property of light according to the conditions of currently acceptable experimental setups pertaining to special relativity, and conclude that this view supports perspectivism.

This dissertation is about human knowledge of reality. In particular, it argues that scientific knowledge is bounded by historically available instruments and theories; nevertheless, the use of several independent instruments and theories can provide access to the persistent potentialities of reality. The replicability of scientific observations and experiments allows us to obtain explorable evidence of robust entities and properties. The dissertation includes seven chapters. It also studies three cases – namely, Higgs bosons and hypothetical Ϝ-particles (section 2.4), the Ptolemaic and (...) Kepler model of the planets (section 6.7), and the special theory of relativity (chapter 7). -/- Chapter 1 is the introduction of the dissertation. Chapter 2 clarifies the notion of the real on the basis of two concepts: persistence and resistance. These concepts enable me to explain my ontological belief in the real potentialities of human-independent things and the implications of this view for the perceptual and epistemological levels of discussion. On the basis of the concept of “overlapping perspectives”, chapter 3 argues that entity realism and perspectivism are complementary. That is, an entity that manifests itself through several experimental/observational methods is something real, but our knowledge of its nature is perspectival. Critically studying the recent views of entity realism, chapter 4 extends the discussion of entity realism and provides a criterion for the reality of property tokens. Chapter 5, in contrast, develops the perspectival aspects of my view on the basis of the phenomenological-hermeneutical approaches to the philosophy of science. This chapter also elaborates my view of empirical evidence, as briefly expressed in sections 2.5 and 4.5. Chapter 6 concerns diachronic theoretical perspectives. It first explains my view of progress, according to which current perspectives are broader than past ones. Second, it argues that the successful explanations and predictions of abandoned theories can be accounted for from our currently acceptable perspectives. The case study of Ptolemaic astronomy supports the argument of this chapter. Chapter 7 serves as the conclusion of the dissertation by applying the central themes of the previous chapters to the case study of special relativity theory. I interpret frame-dependent properties, such as length and time duration, and the constancy of the speed of light according to realist perspectivism. (shrink)

In this paper, we provide a macro level analysis of the visibility of philosophy of science in the sciences over the last four decades. Our quantitative analysis of publications and citations of philosophy of science papers, published in 17 main journals representing the discipline, contributes to the longstanding debate on the influence of philosophy of science on the sciences. It reveals the global structure of relationships that philosophy of science maintains with science, technology, engineering and mathematics and social sciences and (...) humanities fields. Explored at the level of disciplines, journals and authors, this analysis of the relations between philosophy of science and a large and diversified array of disciplines allows us to answer several questions: what is the degree of openness of various disciplines to the specialized knowledge produced in philosophy of science? Which STEM and SSH fields and journals have privileged ties with philosophy of science? What are the characteristics, in terms of citation and publication patterns, of authors who get their philosophy of science papers cited outside their field? Complementing existing qualitative inquiries on the influence of specific authors, concepts or topics of philosophy of science, the bibliometric approach proposed in this paper offers a comprehensive portrait of the multiple relationships that links philosophy of science to the sciences.

In this paper, I seek to explain Suhrawardī’s method of writing his allegories – how he draws upon his philosophical principles to construct forms and plots of his stories. To do so, I begin by delineating two key doctrines of his Illuminationist (Ishrāqī) ontology: the world of Forms (‘ālam al-muthul) and the discontinuous imaginal world (‘ālam al-mithāl al-munfaṣil). I provide an account of the history of these two doctrines and the nature of these two worlds, and then consider some of (...) their functions for, and effects on, Suhrawardī’s explanations and analyses. I will then deal with Suhrawardī’s allegories, pinpointing particular effects of the belief in the world of Forms and the imaginal world on his symbolisms and allegories. Distinguishing three main spiritual-mystical notions in Suhrawardī’s allegories, I elaborate upon the role of the above two doctrines in his construction of characters and fictional events, whereby I demystify certain symbols in these stories. I conclude that there is a close tie between Suhrawardī’s allegories and his philosophical doctrines. Thus, his spiritual doctrines are presented in a symbolic form in certain allegorical characters and adventures. The deployment of characteristics of the world of Forms and the imaginal world plays a central role here. (shrink)

In this work, Muhsin Mahdi--widely regarded as the preeminent scholar of Islamic political thought--distills more than four decades of research to offer an authoritative analysis of the work of Alfarabi, the founder of Islamic political philosophy. Mahdi, who also brought to light writings of Alfarabi that had long been presumed lost or were not even known, presents this great thinker as his contemporaries would have seen him: as a philosopher who sought to lay the foundations for a new (...) understanding of revealed religion and its relation to the tradition of political philosophy. Beginning with a survey of Islamic philosophy and a discussion of its historical background, Mahdi considers the interrelated spheres of philosophy, political thought, theology, and jurisprudence of the time. He then turns to Alfarabi's concept of "the virtuous city," and concludes with an in-depth analysis of the trilogy, Philosophy of Plato and Aristotle. This philosophical engagement with the writings of and about Alfarabi will be essential reading for anyone interested in medieval political philosophy. (shrink)

This study investigates global properties of three categories of English text: canonical fiction, non-canonical fiction, and non-fictional texts. The central hypothesis of the study is that there are systematic differences with respect to structural design features between canonical and non-canonical fiction, and between fictional and non-fictional texts. To investigate these differences, we compiled a corpus containing texts of the three categories of interest, the Jena Corpus of Expository and Fictional Prose. Two aspects of global structure are investigated, variability and self-similar (...) patterns, which reflect long-range correlations along texts. We use four types of basic observations, the frequency of POS-tags per sentence, sentence length, lexical diversity, and the distribution of topic probabilities in segments of texts. These basic observations are grouped into two more general categories, the lower-level properties and, which are observed at the level of the sentence, and the higher-level properties and, which are observed at the textual level. The observations for each property are transformed into series, which are analyzed in terms of variance and subjected to Multi-Fractal Detrended Fluctuation Analysis, giving rise to three statistics: the degree of fractality () of the fractal spectrum. The statistics thus obtained are compared individually across text categories and jointly fed into a classification model. Our results show that there are in fact differences between the three text categories of interest. In general, lower-level text properties are better discriminators than higher-level text properties. Canonical fictional texts differ from non-canonical ones primarily in terms of variability in lower-level text properties. Fractality seems to be a universal feature of text, slightly more pronounced in non-fictional than in fictional texts. On the basis of our results obtained on the basis of corpus data we point out some avenues for future research leading toward a more comprehensive analysis of textual aesthetics, e.g., using experimental methodologies.

Freedom is one of the major elements in Henry James’s The Portrait of a Lady. In an age when American women were usually engaged or married, James’s heroine, Isabel, was somewhat ahead of her time in hoping for a marriage in which she could still be independent. She was very fond of her liberty and afraid of losing it, but does her return to her husband, Osmond, at the end of the novel suggest that she has put an end to (...) her eagerness for freedom? It is an underlying argument of this study that James’s novel, in its last scene, covers a different aspect of freedom which, through a Schopenhauerian approach, delivers a different insight into liberty. This perception of freedom in The Portrait of a Lady has never been considered in connection with Arthur Schopenhauer’s view on the experience of freedom. The implicit critical point on which the paper is founded is that, although Schopenhauer is not conspicuously mentioned in James’s notes, there is important evidence that shows the convergence between the thoughts of Schopenhauer and Henry James; that is, that evidence through which this study aims to analyse the heroine’s final decision in the last scene.

This paper proposes a way to understand the meaning of reality (in science) on the basis of the concepts of persistence and resistance. It first supports the ontological view that reality consists of persistent potentialities, which resist being excluded from existence. A study of the cases of the Higgs boson and the hypothetical Ϝ-particle helps to illustrate how real entities persist and resist. The paper then suggests that, perceptually speaking, the results of ordinary perception or observational processes persistently appear under (...) appropriate conditions, and they resist disappearance even when the appropriate conditions are not completely prepared. Finally, it argues that, epistemologically speaking, a truthful theory resists being falsified and persists across replicable observations and experiments. (shrink)

Muslim scholars have had different approaches toward modern technologies. Defining the situation in various Islamic countries is dependent on knowing the approaches adopted by their scholars. These approaches create norms which can shed light on the reasons for the success and failure of access to technology and its transference. The present article sets out to analyze the views of the Qom seminary scholars in Iran about the development of modern technologies within the framework of the development sociology using the qualitative (...) methodology of grounded theory. To this end, such techniques as conducting interviews and investigating documents have been used to gather the data. The authors find four paradigm models regarding modern technologies among the Qom seminary scholars. These models are classified into two general categories: optimistic and pessimistic. In the end, an “appropriate technology” approach is introduced as an approach singled out by the researchers. (shrink)

Speeches of the author on theory of knowledge in the context of Islamic philosophy.

Nous étudions un traité scientifique en langue arabe, achevé à Belgrade en 1779. Son titre est L’Offrande du converti pour ranimer la flamme éteinte. Il ne fut jamais imprimé, mais dix copies, d’aspect semblable à celui des manuscrits arabes traditionnels, attestent de sa circulation dans l’Empire ottoman. L’auteur, un converti à l’islam qu’on appelait Osman Efendi, y aborde la géométrie euclidienne, la géométrie d’arpentage, la dynamique galiléenne et leurs applications aux sciences militaires. Il affiche son ambition de « faire revivre (...) et renouveler » la géométrie, « science oubliée et délaissée », et révèle in fine avoir pour cela traduit des livres allemands et français. Après un essai de reconstruction de la biographie d’Osman Efendi, nous montrerons que son ouvrage est en réalité une production élaborée, dépassant largement la simple démarche de traduction. Montage soigneux de différentes sources européennes que nous identifierons, il incorpore aussi un grand nombre d’éléments directement empruntés au savoir islamique de la tradition vivante. Il est ainsi le témoin remarquable d’une tentative de constitution d’un savoir hybride euro-islamique. (shrink)

In pursuit of moralities and beliefs in the grey area of culture, the researchers carried out a study on Top Notch series to pinpoint the trace of ethics. This paper seeks to unfold the representation of ethics as an indubitable part of culture in Top Notch series. After having extracted all culturally and ethically-related topics and texts of Top Notch Series, 25 instances, featuring 6 patterns, were collected. Later these 6 patterns were dubbed as: violence, superstition, modesty,individualised ethics, religion, and (...) modernity. Having analysed these 6 themes, well representing beliefs and moralities, the researchers came to the conclusion that both misrepresentation of ethics and underrepresentation and overrepresentation of different cultures are at work. The results show a reconsideration of therepresentation of ethics, or better to say reconsideration of misrepresentation of ethics which might find its root in wrong dominance of culture over ethics.

This study assessed the validity of instrument including various negative psychological and physical behaviors of commuters due to the public transport delay. Instruments have been mostly evaluated by parametric method of item response theory. However, the IRT has been characterized by some restrictive assumptions about the data, focusing on detailed model fit evaluation. The Mokken scale analysis, as a scaling procedure is a non-parametric method, which does not require adherence to any distribution. The results of the study show that in (...) most regards, our instrument meets the minimum requirements highlighted by the MSA. However, the instrument did not adhere to the minimum requirements of the “scalability” for two variables including “stomach pain” and “increased heart rate”. So, modifications were proposed to address the violations. Although MSA technique has been used frequently in other fields, this is one of the earliest studies to implement the technique in the context of transport psychology. (shrink)

Many ordinary things are made up of material things. For example, the statue of Ferdousi in the University of Tehran is made up of a particular piece of bronze. Calling the relation between the statue of Ferdousi and that piece of bronze material constitution, many philosophers have claimed that this relation between a material thing and the thing that it constitutes is identity. Baker, in contrast, believes that these things have genuine unity without necessary identity. In this article, I first (...) illustrate the principles of Baker’s theory and his explanation of this relation. Then I will assess the theory against objections. I will conclude that this theory can successfully explain relation between many of material things, but concerning things belonging to human beings, the theory fails to introduce a criterion for constitution.

Engineering, as a complex and multidimensional practice of technology development, has long been a source of ethical concerns. These concerns have been approached from various perspectives. There are ongoing debates in the literature of the philosophy of engineering/technology about how to organize an optimized view of the values entailed in technology development processes. However, these debates deliver little in the way of a concrete rationale or framework that could comprehensively describe different types of engineering values and their multi-aspect interrelations in (...) real engineering practices. Approaching engineering values from a meaning-based perspective, as in this paper, can be a reliable method of tackling such a controversial problem. This paper therefore proposes that technology development be considered a systemic normative practice and attempts to provide a comprehensive view of various built-in values, their different origins and features, and a way of prioritizing them in real engineering processes. Studying two cases of the Zayandeh Rood Dam and the Abbasi Dam will lead to practical insights into how to understand norms in technology development and incorporate them into engineering practice.

Technological enthusiasm is a value that can influence engineering, shape technologies and subsequently transform human lifestyles. Despite its significant role, up until now, there has been little research done on this value. The dominant idea is that this value is commendable. However, based on consequentialism, a recently proposed idea describes TE as neither morally commendable nor reprehensible. In this paper, three arguments are presented against this recent idea, and a new idea is introduced, which challenges not only commendation for TE (...) but also neutrality of TE. Further, it is shown that a virtue ethics approach can be adopted to evaluate the moral role of TE. In the approach, TE can be considered a character trait or a virtue/vice. Then, three arguments are proposed to indicate that TE is not a virtue but a vice. This paper illustrates some advantages of virtue ethics in ethical evaluation of a problem in which consequentialism or utilitarianism is not effective. (shrink)

A number of animal species from different lineages live socially. One of the features of social living is the formation of dominance hierarchy. Despite its obvious benefit in the survival probability of the species, the hierarchical structureitself poses psychological and physiological burden leading to the chronic activation of stress related pathways. Considering these apparently conflicting observations, here we propose that social hierarchy can act as a selective force in the evolution of social species. We also discuss its role on social (...) psychology. (shrink)
