The principles of medical ethics, common as they are in the world at the present time, have been formed in the context of Western secular communities; consequently, secular principles and values are inevitably manifested in all corners of medical ethics. Medical ethics is at its infancy in Iran. In order to incorporate medical ethics into the country's health system, either the same thoughts, principles, rules, and codes of Western communities should be translated and taught across the country, or else, if (...) the principles and values and consequently the prominent moral rules and codes of Western medical ethics are not consistent with the culture, customs, and religion of our country, then new principles and values should be formulated that are more in harmony with our society. According to the available literature in Iran, the four principles proposed by Beauchamp and Childress do not contradict the Islamic-Iranian culture and can thus be generally applied in the mentioned context. However, the application of these four principles and their derivatives requires careful examination and adaptation to Islamic ethics. A comparison of the ontological, anthropological and epistemological foundations of secular and Islamic attitudes shows the differences between these two attitudes to be deep-rooted. “Rationalism,” “scientism,” and “humanism” are the main foundations of secularism, whereas “Godcentrism,” “pure human servitude to God,” the belief in “returning of humans to God,” “resurrection day,” and also human's accountability to God are all fundamental beliefs and principles of religion for Muslims of all cults and sects. It can thus be concluded that the principles of secularist thought are different from and to some extent inconsistent with the principles of Islam. Instructions derived from secular thought can therefore not be implemented in an Islamic community; rather, these communities should adopt Islamic foundations as the source for the norms and standards of their medical ethics. The capacities of religious thought make possible the formation of an ethical system consistent with Islamic Ummah. (shrink)

Background: Nurses require empowerment if they are to make ethical decisions. Ethical empowerment has always been one of the main concerns in nurse training programs. Research aim: The present study was conducted to determine the effect of an ethical empowerment program on critical care nurses’ ethical decision-making. Research design: This is a clinical trial study with two groups and pre and post design. Participants and research context: In this study, 60 nurses working in Intensive Care Unit were selected through random (...) sampling and then divided into a control and an experimental group after filling out the Moral Sensitivity Questionnaire. Both groups completed the questionnaire again immediately and 2 months after the ethical empowerment workshop had been held for the experimental group. The collected data were analyzed in SPSS-16 using descriptive and inferential statistics. Ethical considerations: The goals of the study were explained to the participants and then a written informed consent was received from them. Findings: The results showed no significant differences between the two groups in terms of their ethical sensitivity scores at the beginning of the study; however, immediately and 2 months after the intervention, the mean score increased significantly in the experimental group. Moreover, the scores obtained 2 months after the workshop increased compared to the pre-intervention scores but showed a drop compared to the scores reported immediately after the workshop. Discussion: The ethical empowerment program, given to the critical care nurses in this study, improved their ethical sensitivity in making decisions significantly over time. Despite the extensive methods, available for teaching nursing ethics, the ethical empowerment program, adopted in this study, had long-lasting effects in terms of ameliorating the process of ethical decision-making in clinical situations. Conclusion: The ethical empowerment of nurses requires the adoption and application of proper methods and patterns of complying with nursing ethics. (shrink)

Medical ethics is a practical key element in the medical curriculum. Movies can be used as an effective and innovative way to involve students in discussions and reflections on ethical issues. This study aimed to evaluate the appropriateness of medical movies as a tool in medical ethics education. During the last teaching session of the medical ethics courses, the movie “Extreme Measures” was shown to the medical students. The present study is a descriptive-analytical study of 302 students’ manuscripts. The quantitative (...) content analysis of the students’ manuscripts was carried out using a checklist that contained 11 titles and 75 subtitles. Each student’s checklist was compared to the student’s final exam score. The most recognized issue was justice, and the least recognized one was confidentiality and privacy. Nonmaleficence, respecting autonomy and informed consent, honor and integrity, end of life, duty and responsibility, conflict of interest, beneficence, relationship with colleagues and altruism were located in-between. There was a relationship between students’ final exam scores and their manuscripts’ scores. According to our findings, relevant movies with standard categorization can be used as a useful method for medical ethics education and assessment. (shrink)

Publication date: 30 March 2017 Source: Author: Tahereh Rezaei, Mohsen Hanif Art in general and fiction in particular have had close affinities with politics throughout history. When there is a close tie between a narrative fiction and political issues then critics may deem it as “committed fiction”. Political fiction is at the crossroads of political science and the art of fiction. And more often than not, novelists are involved with politics but not all of them are dubbed as (...) or even consider themselves to be political novelists. In this article I attempt to investigate political fiction as a distinct genre produced consciously by a range of novelists and critics. The authors discussed in this paper demonstrate dissimilar perspectives on freedom and democracy. Also, regarding political fiction and the responsibility of author, we will see how divergent is the attitudes of critics such as George Orwell, Allen Robbe-Grillet, Juan Goytisolo, Mario Vargas Llosa and Isabel Allende.

Focusing on some contemporary Islamic reformers’ solutions, in particular, Abolkarim Soroush, Mohsen Kadivar, and Fazlur Rahman, to concrete issues in Muslim societies, this article examines two different methodological strategies of alternative readings of the Sunna: an archeological one and a genealogical one. In the archeological perspective, the holy text has been considered as a repository of answers to all sorts of questions. Through a pathological analysis, this view suggests solutions to correct distortions and looks for new windows seeking an (...) original interpretation of the Qur’an. The genealogical view, on the other hand, puts aside this pathology and instead insists on the idea of the contingency of any interpretation. Regardless of accuracy and validity, according to the genealogical view, all interpretations have addressed temporal and contextual questions. What is important in this perspective is not returning to an original source for finding the exact message of Allah, or correcting previous interpretations, but recurrently referring to an open-ended text in order to explore the futures of the Qur’an.

We use the left self‐distributive axiom to introduce and study a special class of weak Heyting algebras, called self‐distributive weak Heyting algebras (SDWH‐algebras). We present some useful properties of SDWH‐algebras and obtain some equivalent conditions of them. A characteristic of SDWH‐algebras of orders 3 and 4 is given. Finally, we study the relation between the variety of SDWH‐algebras and some of the known subvarieties of weak Heyting algebras such as the variety of Heyting algebras, the variety of basic algebras, the (...) variety of subresiduated lattices, the variety of reflexive WH‐algebras (RWH‐algebras), and the variety of transitive WH‐algebras (TWH‐algebras).

Nursing, a scientific and practical discipline, faces continuing challenges of finding new direction in order to decipher its core values and develop current ethical codes for nursing practice. In 2009–10, 28 nurses were purposely selected and interviewed using a semi-structured format in focus groups and individually. Thematic Content Analysis helped explore the perception of Iranian nurses on ethical values in patient care. Seven major themes emerged: respect for dignity, professional integrity, professional commitment, developing human relationships, justice, honesty, and promoting individuals (...) and the nursing profession. Iranian nurses revealed a unique and culture-based set of ethical values. This study found that Iranian nurses place a greater emphasis on preserving the dignity of those accompanying the patient and in showing regard for patients' religious beliefs in a gender appropriate environment.

There are two dimensions to Fine’s truthmaker semantics. One involves a claim about the nature of propositions: propositions are not structural and nothing but sets of their possible truthmakers, and the other talks about the relation between truthmaking and Boolean operations. In this paper, I show that a claim by Fine in the latter dimension—that truthmaking is distributed over “or”—faces a counterexample. I will then go on to argue that one possible way to do away with the counterexample is to (...) restrict truthmakers to fundamentals, namely entities that are not grounded in anything else. This would, nevertheless, pose a problem for the first dimension of truthmaker semantics: certain distinct propositions would fail to be distinct. (shrink)

In this paper an Artificial Neural Network (ANN) model was used to help cars dealers recognize the many characteristics of cars, including manufacturers, their location and classification of cars according to several categories including: Make, Model, Type, Origin, DriveTrain, MSRP, Invoice, EngineSize, Cylinders, Horsepower, MPG_Highway, Weight, Wheelbase, Length. ANN was used in prediction of the number of miles per gallon when the car is driven in the city(MPG_City). The results showed that ANN model was able to predict MPG_City with 97.50 (...) % accuracy. The factor of DriveTrain has the most influence on MPG_City evaluation. Similar studies can be carried out for the evaluation of other characteristics of cars. (shrink)

Society Must Be Defended is a collection of Michel Foucault’s courses at the College de France in 1976. In this volume, Foucault discusses the emergence of a new technology of domination called biopower. It is a power that is not “individualizing”, but “massifying”, that is directed at man as a member of a “species”. Biopolitics exerts control over relations between the human races. Yet, some critics claim that Foucault’s biopower does not address colonial societies and problems. This paper argues that (...) Foucault’s theory of biopower could be applied to the postcolonial discourse, too. To trace Foucauldian biopower in postcolonial literature, the authors of this article have focused on E. M. Forster’s A Passage to India. In this paper, the plot and the dialogue of Forster’s novel is studied based on Foucault’s theory of biopower as discussed in his Society Must Be Defended. It is concluded that in Forster’s novel, it can be noticed that the English power, which dominated early twentieth century Indian society, employs biopower to subjugate the Indian population. The English officials control India not merely by means of disciplinary institutions, but by manufacturing norms for an entire race which are explainable in terms of Foucault’s theory of biopower.

There are some texts about moral sentences in the Islamic logical literature especially in the logical books of Ibn Sina that have been interpreted in completely opposite ways. Relying on these texts, some scholars take Ibn Sina to be proposing a non-cognitive theory of ethics and to the contrary some scholars hold that he is a proponent of a sort of moral intuitionism. Reflecting on the alleged textual evidence in Ibn Sina’s books, I propose a middle way in the interpretation (...) that accepts the cognitive status of the moral sentences but at the same time rejects intuitionism.

Almost every case of visual experience is as of a unified state of affairs and as of one or more specific particulars. I argue that a view on which the content of visual experience is a singular proposition does a better job at explaining these two features of visual experience than three popular theories: the Complex Property Theory, Generalism, and Fregean Particularism. The defended view, however, entails that there are no visual hallucinations traditionally understood. I make the case for the (...) plausibility of this consequence. (shrink)

Although Avicenna does not explicitly develop a ‘theory of intentionality', one can reconstruct his account of intentionality through an analysis of his thoughts on the relation between mind, meaning, and thing. We take up this task in this paper through an analysis of Avicenna's theory of the considerations of quiddity. First, we clarify Avicenna's idea of ‘quiddity', and show how it functions as a core of ‘meaning' which remains identical in its different modes of realization. Second, through an examination of (...) the very notion of ‘consideration' (i‘tibār), we distinguish between two aspects of the mind, i.e. mental act and mental existence. This helps us clarify what Avicenna means by the existence of a quiddity in mind and in what sense, if any, it is essential to intentionality. Third, addressing the problem of the relation between ‘mental existence' and ‘external existence’, we show how the mode of existence of a quiddity, including its concrete existence, is posited in and through intentionality. This implies that both being and quiddity are moments of the intentional object, and thus, intentionality, for Avicenna, is a dyadic relation between the intentional act and the intentional object. We conclude by reconstructing the structure of intentionality in Avicenna. (shrink)

In “Is Justified True Belief, Knowledge?” Gettier shows us two counter examples of analyzing Knowledge, as “Justified True Belief” or “JTB”. Lots of scholars have reconstructed similar counter examples to JTB but we can see they follow a similar algorithm. Other scholars have tried to re-analyze knowledge by adding a fourth element to JTB and reformulating knowledge in a “JTB+X” formula and some replaced justification with another alternative component (Y) and proposed a “YTB” analysis of knowledge. In this article I (...) first overview Gettier’s problem and I show that we can construct a similar Gettier problem for each “JTB+X” or “YTB” formula. After that, I will focus on re-analyzing knowledge with a phenomenological attitude that can avoid Gettier’s problem. (shrink)

Given a theory T of a polynomially bounded o-minimal expansion R of $${\bar{\mathbb{R}} = \langle\mathbb{R}, +,., 0, 1, < \rangle}$$ with field of exponents $${\mathbb{Q}}$$, we introduce a theory $${\mathbb{T}}$$ whose models are expansions of dense pairs of models of T by a discrete multiplicative group. We prove that $${\mathbb{T}}$$ is complete and admits quantifier elimination when predicates are added for certain existential formulas. In particular, if T = RCF then $${\mathbb{T}}$$ axiomatises $${\langle\bar{\mathbb{R}}, \mathbb{R}_{alg}, 2^{\mathbb{Z}}\rangle}$$, where $${\mathbb{R}_{alg}}$$ denotes the real (...) algebraic numbers. We describe types and definable sets in our models and prove that $${\mathbb{T}}$$ is dependent. (shrink)

This study explored the associations between the Dark Triad traits and mental well-being in a Korean adult sample. The role of the conceptions of happiness as mediators of these associations was also investigated. Eight conceptions of happiness, 3 dimensions of hedonic well-being, and 2 dimensions of eudaimonic well-being were included in the study. The results showed that Machiavellianism and psychopathy were negatively and narcissism was positively associated with well-being. The pattern of associations between the dark triad and conceptions of happiness (...) showed that Machiavellianism and psychopathy were associated with valuing personal happiness but also considering it to be out of one’s control, and to have negative consequences when achieved. People high on narcissism endorsed generally positive notions of happiness. Results showed that conceptions of happiness functioned as partial mediators in the relationships between the dark triad and well-being. Hence, it seems that the dark triad traits provide a context for the formation of certain beliefs surrounding the nature and value of well-being, which per se influence experienced levels of well-being.

There are two main theories of ontological commitment: the quantifier view, and the truthmaker view. Since there are some truths that apparently commit us to certain entities, but actually do not, any ontological commitment theory must also contain an ontological reduction theory. Advocates of the quantifier view propose the paraphrasing method of reduction, while advocates of the truthmaker view propose the supervenience method. In this paper, after a brief discussion of the quantifier view, I propose a modified version of truthmaker-based (...) ontology, and show that a plausible account of the supervenience method can be deduced from my version. I then show that the supervenience method could explain why the paraphrasing method is successful, albeit that there are some cases in which the supervenience method works but the paraphrasing method does not, or so it seems prime facie. I also argue that according to the truthmaker view we must accept composite objects as something over and above the particles which constitute them. (shrink)

Source: Author: Mohsen Mehrara, Yazdan Gudarzi Farahani, Farzan Faninam, Abbas Rezazadeh Karsalari This paper examines the relationship between stock market index and macroeconomic policies on Iran's economy using quarterly data in the period 1999-2013. This study employed cointegration test and vector autoregressive models to examine relationships between the stock market index and the macroeconomic variables. The empirical results reveal that a positive money shock can increase stocks return. According to impulse responses, the government expenditure had a slight impact on (...) stocks return in the short term. But the government expenditure has a positive effect on exchange index in long run. Also the effect of taxes on the stock's price index is negative, so that it reaches its maximum level after the third lag and then alleviates. The GDP shock has positive effect on the stock's price index. Increase in production level leads to increase in earnings and profitability, leading to a positive response from stocks index. Therefore the results showed that the macroeconomic variables such as inflation, exchange rate and GDP have significant effects on Tehran exchange price index. So the hypothesis that the improving economic factors can have a useful role in the booming capital market is confirmed. Also the effect of fiscal policy factors such as tax revenues and government expenditures is more than monetary policy factors on stock returns. ]]>. (shrink)

Background and objectivesThe study of brain functional connectivity alterations in children with Attention-Deficit/Hyperactivity Disorder has been the subject of considerable investigation, but the biological mechanisms underlying these changes remain poorly understood. Here, we aim to investigate the brain alterations in patients with ADHD and Typical Development children and accurately classify ADHD children from TD controls using the graph-theoretical measures obtained from resting-state fMRI.Materials and methodsWe investigated the performances of rs-fMRI data for classifying drug-naive children with ADHD from TD controls. Fifty (...) six drug-naive ADHD children and 56 age matched TD controls were included in this study. The graph measures extracted from rs-fMRI functional connectivity were used as features. Extracted network-based features were fed to the RFE feature selection algorithm to select the most discriminating subset of features. We trained and tested Support Vector Machine, Random Forest, and Gradient Boosting using Peking center data from ADHD-200 database to classify ADHD and TD children using discriminative features. In addition to the machine learning approach, the statistical analysis was conducted on graph measures to discover the differences in the brain network of patients with ADHD.ResultsAn accuracy of 78.2% was achieved for classifying drug-naive children with ADHD from TD controls employing the optimal features and the GB classifier. We also performed a hub node analysis and found that the number of hubs in TD controls and ADHD children were 8 and 5, respectively, indicating that children with ADHD have disturbance of critical communication regions in their brain network. The findings of this study provide insight into the neurophysiological mechanisms underlying ADHD.ConclusionPattern recognition and graph measures of the brain networks, based on the rs-fMRI data, can efficiently assist in the classification of ADHD children from TD controls.

A hypergroup, as a generalization of the notion of a group, was introduced by F. Marty in 1934. The first book in hypergroup theory was published by Corsini. Nowadays, hypergroups have found applications to many subjects of pure and applied mathematics, for example, in geometry, topology, cryptography and coding theory, graphs and hypergraphs, probability theory, binary relations, theory of fuzzy and rough sets and automata theory, physics, and also in biological inheritance.

Proactively including the ethical and societal issues of new technologies could have a positive effect on their acceptance. These issues could be captured in terms of values. In the literature, the values stakeholders deem important for the development of technology have often been identified. However, the relative ranking of these values in relation to each other have not been studied often. The best worst method is proposed as a possible method to determine the weights of values, hence it is used (...) in an evaluative fashion. The applicability of the method is tested by applying it to the case of smart meters, one of the main components of the smart grid. The importance of values is examined for three dimensions of acceptance namely sociopolitical, market, and household acceptance. (shrink)

Armstrong appeals to the existence of totalities in order to solve the problem of negative truths. The totality of first-order states of affairs is a truthmaker for all negative truths, but it involves things which are irrelevant to many such truths. To solve this problem, Armstrong claimed that negative truths have minimal truthmakers which usually consist in totalities smaller than the totality of first-order states of affairs. Merricks objects to this claim by arguing that given Armstrong’s definition of minimal truthmakers, (...) the totality of first-order states of affairs is a minimal truthmaker for every negative truth. In this article, I respond to Merricks’s objection. I will first show that the definition of minimal truthmakers that he proposes is not plausible. However, Merricks’s objection, I will argue, also works on the standard definition of minimal truthmakers. I will then show that for independent reasons, the standard definition should be revised, and, given my revised definition, Merricks’s objection fails. (shrink)

Rough set theory is an excellent mathematical tool for the analysis of a vague description of actions in decision problems.

The conventional production model based on extensive use of chemical inputs such as pesticides is increasingly challenged. Organic agriculture is considered as one of the most important alternative agricultural systems to produce healthy food without any chemicals. Current models are not suitable for prediction of environmental behaviors. The current study aims to analyze the diffusion of organic agriculture to produce healthy food with the environmental sociology approach among farmers. The study was conducted using the survey research and multi-stage random sampling (...) in Fars province, in the south of Iran. The samples included 215 farmers. The reliability of the questionnaire was confirmed by conducting a pilot study out of the main sample. The results showed that the farmers have strong attitude to the environment and are for the most part, highly intentioned to perform organic activities. Based on the results, the farmers’ intention toward adoption of organic agriculture, environmental identity, and responsibility of pro-environmental behavior, and their moral norms play an important role to accept organic agricultural activities. There are also some effective factors in implementation of organic agriculture including farmers` increasing awareness about the principles of organic farming, controllability of environmental behaviors as well as their accessibility to the resources and facilities for organic farming. The study emphasized that the attitude and enhancing the knowledge do not lead to pro-environmental behaviors and organic activities directly. Using the models and environmental sociology theories is more efficient to explain pro-environmental behaviors. To this aim, some suggestions were presented to increase the adoption of organic activities and persuade the Iranian farmers to select this kind of cultivation. (shrink)

With the realization of the promised global village, media, particularly online newspapers, play a significant role in delivering news to the world. However, such means of news circulation can propagate different ideologies in line with the dominant power. This, coupled with the emergence of so-called Islamic terrorist groups, has turned the focus largely on Islam and Muslims. This study attempts to shed light on the image of Islam being portrayed in Western societies through a Critical Discourse Analysis approach. To this (...) end, a number of headlines about Islam or Muslims have been randomly culled from three leading newspapers in Western print media namely The Guardian, The Independent and The New York Times. This study utilizes “ideological square” notion of Van Dijk characterized by “positive presentation” of selves and “negative presentation” of others alongside his socio-cognitive approach. Moreover, this study will take the linguistic discourses introduced by Van Leeuwen regarding “representing social actors and social practices” into consideration. The findings can be employed to unravel the mystery behind the concept of “Islamophobia” in Western societies. Besides, it can reveal how specific lexical items, as well as grammatical structures are being employed by Western media to distort the notion of impartiality. (shrink)

Recently, research on uncertainty modeling is progressing rapidly and many essential and breakthrough stud ies have already been done. There are various ways such as fuzzy, intuitionistic and neutrosophic sets to handle these uncertainties. Although these concepts can handle incomplete information in various real-world issues, they cannot address all types of uncertainty such as indeterminate and inconsistent information.

Divine Motivation theory is an ethical theory with a theological foundation, attempting to explain the relation between religion and morality in the context of Christian theology with emphasizing on neo-Aristotelian and motivation-based ethics. This theory that is presented by Linda Zagzebski, provides a new form of virtue ethics that God's motives, especially that of love, are foundations of moral life and these motivational states are considered ontologically and explanatorily the basis for all moral properties and values. This theory uses five (...) steps to advance its destination. In the first step, this theory proves the personhood of God. In the second step, it argues that God has perfect virtues and motives. In the third step, it shows that God's motive in the Creation is motive of love that is the central and fundamental divine motive. In the fourth step, it discusses the doctrine of imitatio Dei and focuses on the problems of this doctrine. In the last step, it attempts to link this doctrine to the doctrine of the incarnation to resolve its problems. (shrink)

Self-esteem (a positive attitude toward oneself) and self-efficacy (confidence in one's ability to perform actions that lead to desired outcomes) are predictors of affective well-being. However, there is a lack of longitudinal research on their relative importance in predicting positive and negative affect. This study sought to examine the relative strength of these 2 variables in predicting affective well-being. Data from the German Aging Survey (DEAS), collected in 4 waves between 2008 and 2017, were used. The random-intercept cross-lagged panel model (...) was used for data analysis. Within-person results showed that self-esteem and self-efficacy did not predict future levels of negative affect. Self-esteem, but not self-efficacy, was found to be a predictor of future levels of positive affect. In addition, positive affect predicted future self-efficacy. A longitudinal mediation model showed that self-esteem predicted future self-efficacy via positive affect. Thus, self-esteem contributes directly to future levels of positive affect and indirectly to future levels of self-efficacy. (shrink)

Application of technologies has an important role in agricultural development. Identifying and assessing the impacts of agricultural technologies is necessary. This study aimed at assessing the impacts of laser levelling economically, socially, environmentally, and technically in the viewpoint of the agricultural experts and identifying factors determining their perception of the impacts. The study samples (151 experts) were selected using multi-stage random sampling in Fars Province, Iran. The results revealed that experts considered uniform distribution of water, using conservation tillage, facilitating agricultural (...) activities, decreased water consumption and decrease of water wasting as the most important technical impacts of laser levelling technology. The most environmentally important impacts were the decrease of soil erosion and retention of crop residues. Experts stated the most significant social impacts as improvement in villages living conditions and sense of belonging to rural areas. Besides, an increase of income and reduction of inputs costs were among the economic impacts of laser levelling technology. According to the results, attitude towards water and soil resources conservation and environmental beliefs had the highest direct effect on individual perception toward impacts. Practical recommendations have been presented based on the results of the study. (shrink)
