Probability distributions play an essential role in modeling and predicting biomedical datasets. To have the best description and accurate prediction of the biomedical datasets, numerous probability distributions have been introduced and implemented. We investigate a novel family of lifetime probability distributions to represent biological datasets in this paper. The proposed family is called a new flexible logarithmic- X family. The suggested NFLog- X family is obtained by applying the T- X method together with the exponential model having the PDF m (...) t = e − t. Based on the NFLog- X approach, a three parameters probability distribution, namely, a new flexible logarithmic-Weibull distribution is introduced. The method of maximum likelihood estimation is adopted for estimating the parameters of the NFLog- X family. In the end, we examine three different biological datasets in order to give a thorough numerical research that illustrates the NFLog-Wei distribution. Comparisons are made between the analytical goodness-of-fit metrics of the suggested distribution. We made comparison with the alpha power transformed Weibull, exponentiated Weibull, Weibull, flexible reduced logarithmic-Weibull, and Marshall–Olkin Weibull distributions. After performing the analyses, we observe that the proposed method outclassed other competitive distributions. (shrink)

Modern technology plays an important role in our daily lives. Many people use technology for their works, interactions, and special interests such as art. Art as a discipline, which expresses human emotion and creative side, takes a new form for its contextualization with the help of information technology. A neologism for this discipline is “digital art.” Some experts who employ a traditional value in their aesthetical perspective consider this new approach unlikely. Walter Benjamin, an eminent figure from this group, stated (...) that art must have an aura in its production as is the case in paintings. With this aura, the work of art and not artwork has uniqueness of value. However, the problem arises when information technology becomes a predominant tool for the work of art. Digital art does not consider the aura as the core value in defining something as a work of art. Furthermore, digital artists think that art can exist within a digital object and maintain its uniqueness. Parallel with the latter, this article will describe the dispute and make a clear statement that a work of art in the digital age does not require aura. (shrink)

Mamluks reigned in Egypt a long time is an era of Kipchak Turks that have influence management, and Kipchak Turks has been influential in a period in the administration there. During this period, that Turkish rulers do not know Arabic language well, Turkish language is spoken in the palace and also idea of being closer to Turkish manager screated an interest in learning. One of the famous scholars realizing that interest is Abū Ḥayyān al-Andalusī. Abū Ḥayyān by learning Turkish language (...) especially from Fakhr al-dīn Divrigi and analysing written previously works, wrote Kitāb al-Idrāk li-lisān al-Atrāk. This book has consisted of introduction, vocabulary and grammar section. We also aimed in our study to examine Kitāb al-Idrāk in terms of content and than in terms of lexicography of the linguistic branch. -/- SUMMARY Mamluks reigned in Egypt a long time and in its reign Kipchak Turks had influence in management. Because of the Turkish rulers who have military background did not know Arabic language well, Turkish language was spoken in the palace and also idea of being closer of scholars and notable people to Turkish rulers got brought an interest in learning Turkish. One of the famous scholars realizing that interest is Abū Ḥayyān al-Andalusī (d. 745/ 1344). The true name of Abū Ḥayyān is Muḥammed b. Yūsuf b. Ali b. Ḥayyān al-Tawḥīdī and he is an Andalusian linguist and exegete. Abū Ḥayyān who came from a Berber family born in the Matahsharesh village of Granada in 654/1256 and died in Cairo in 28th time 745 (11 July 1344). There is not much information about his family in the sources, but it is mentioned that he has a daughter whose name is Nada, a son named Hayyân in his name, and some grandchildren which are named Muḥammad and Ummu Ḥayyān. Abū Ḥayyān became a famous as Ethīr al-dīn and at the same time, he is also known as Naḥvī, Ghirnātī (Granadian), Ceyyānī, and Nafzī. He took lessons in Granada from great scholars such as Abd al-ḥaķ b. Ali al-Anṣarī, Abū Ḥasan al-Ubbezī, Abū Cafer Aḥmed b. Ibrahīm b. Zubair, Ibn Abū al-Ahvas and became a proficient scholar and teacher in matters such as morphology, syntax, language, commentary, hadith, methodology of Fiqh and Kalām. He wrote about 18 works in different sciences and if we mention some of that are al-Baḥr al-muhīt, al-Nahr al-mād, Tuhfat al-arīb bimā fī al-Qur'ān min al-gharīb and some of his works have reached to our time and some of those did not. Abū Ḥayyān left Andalus for various reasons and visited many centers of science and eventually continued his scientific activities in Cairo. Abū Hayyān, who is a great interest in learning languages, has learned Turkish language with the other popular languages ​​such as Persian, Amharic and Himyarite language and written books about these languages. His mainly works about Turkish language are the Kitāb al-Idrāk li-lisān al-Atrāk, Zehv al-mulk fi naḥv al-Turk, al-Af'al fi lisān al-Turk and al-Durret al-mudiyye fi lughat al-Turkiyye. These works did not reach to our days except Kitāb al-Idrak. Kitāb al-Idrāk consists of three sections, namely introduction, dictionary which includes 2200 words, and grammar that is composed of morphology and syntax and this book which is known as al-Idrāk is written in the Turkish which is spoken in XIV-XVI century tongue and named as Middle Turkish Period-Mamluk Kipchak Turkish. The first chapter begins with basmala and continues with detailed his genealogy, personal record, praise to Allah and salawat and salaam to Prophet Muhammad. After this introduction, it is explained the intention of writing this work. The second chapter is a dictionary which the words are explained in alphabetical order. Although Abū Ḥayyān speaks about 23 letters in the Kipchak alphabet, he does not explain the words related to all, but examines 19 items. In this dictionary, it does not take part some letters, that is letters sā, zāl, zā (letters of lips which is written in English th); letters dâd, ayn, fa (letters of throat) which Arabs use. In the third chapter, there is a part of the tasrif (knowledge of morphology) which is generally called knowledge of morphology today. In this section, it is dealt with about the types of words namely, name of diminutive, name of belonging name, plural, agent name, passive name, exaggerated factor name, infinitive, name indicating the location, name of device, arbitrary name, and idâd (which adds are derivation of noun from name like lık, lik at the end of the word) and then it comes to the end with shadda. Section of syntax which is called by the author as consisted of compound and is prepared according to systematic of Arabic grammar begins with the sentence structure in Kipchak language. After that it continues with definite-ambiguous names, verb (orders, past, imperfect verbs), subject-predicate in nominal sentence, nevāsiḫ (additional actions helped change the meaning of the noun phrase), Arabic leyte which express by the actual wish mold and the like, such as two mef'ūl area of ​​the heart of verbs in Arabic told (I think) were deaf ( Turkmen thinks he), acts like it yet scientists (verb phrase in), acts offender (verb-subject), the abutment of the verb nefiy prepositions, prepositions, the nehiy (ban), passive verbs and naib-i fail (so-called subject); other elements of the sentence, called the act müteallakat are: cognate accusativ, direct object, time period (time complement), the envelope space (located complement), state (envelope), causative object, the exception, the specification, conflict of laws, the annexation, the oat, the dependencies: adjective, conjunction, confirm, the apposition; conditional structure. After these, he mentions to letters of meanings (huruf al-maani), and concludes this chapter with information about the date, place, and name of the author of the book. Abū Hayyān used induction method in the book. Since he gave the forms of the words in double, then the triple, quadruple, quintet and other forms. He tried to teach the pronunciation of words by explaining the etymology of word sand the changes of the voices. He examined the words which are synonyms/ contrasted, synonym voice, singular/plural, and words that are passed by foreign languages into Turkish dialects then they are turned into Turkish word structure; brought out witnesses from proverbs and poetries. As a result, in this work, which consists of dictionary and grammar sections, it can be said that it is used predominantly in linguistic information - translation method . (shrink)

This chapter explores the anti-colonial narrative potential of certain works of cinema taking Aguirre, the Wrath of God and Caché as a case in point. To do so, this chapter first and mainly draws upon the theoretical and normative lens put forward by Gayatri Chakravorty Spivak on the representation of the colonized other and her resulting political and intellectual call for self-reflection on one's privileged Western intellectual positioning. This lens has many normative implications for the ways in which the colonized (...) subject and colonial history are discussed and represented. The partial lack of representation of the colonized other in Aguirre, the Wrath of God leaves the subjectivity of the colonizer in crisis and madness. Second, the narrative of Caché is explored and it is suggested that it resembles the rhetoric of Foucauldian disciplinary power of surveillance turned upside-down thus enforcing the complicit of colonialism to question her privilege.

In this paper an Artificial Neural Network (ANN) model, for predicting the category of a tumor was developed and tested. Taking patients’ tests, a number of information gained that influence the classification of the tumor. Such information as age, sex, histologic-type, degree-of-diffe, status of bone, bone-marrow, lung, pleura, peritoneum, liver, brain, skin, neck, supraclavicular, axillar, mediastinum, and abdominal. They were used as input variables for the ANN model. A model based on the Multilayer Perceptron Topology was established and trained using (...) data set which its title is “primary tumor” and was obtained from the University Medical Centre, Institute of Oncology, Ljubljana, Yugoslavia Test data evaluation shows that the ANN model is able to correctly predict the tumor category with 76.67 % accuracy.

In the past two decades, especially after the financial crisis of 2007–09, the literature for examining the availability of integration between the stock exchanges in developed and developing markets has grown. The importance of this topic stems from the significant implications of the linkage between exchange markets on various decisions taken by interested parties, such as policymakers and investors, in the decisions for portfolio diversification. This study examines the relationship between a developing stock exchange index, Amman Stock Exchange Index, and (...) the number of international indices, including S&P 500, NASDAQ, Nikkei, DAX, CAC, and HSI for 2008-2019. To validate the availability of the linkage between the indices, the author includes various tests of a correlation coefficient, stepwise regression analysis, and artificial neural network. Despite the results indicating that the ANN is more efficient than linear regression in investigating the availability of the relationship between ASEI and international indices, stepwise regression and neural network support this relationship. Furthermore, ANN results revealed that the S&P 500 index and year have the most substantial relationship with ASEI. Our research is theoretically and practically important; policymakers and investors can benefit from our findings. Future studies may explore the effect of different international stock market indices on ASEI or other developing markets. Further studies can use macroeconomic factors to build prediction models for stock market indices. (shrink)

The dominant approach to understanding Islamic Business Ethics has been based almost exclusively on either interpretations of the Qur’an and Sunna or influenced by Western understanding of Islam and ethics. However, there is a rich—largely ignored-tradition of ethical analysis conducted by Muslim philosophers which would broaden our understanding of Islamic ethics and hence IBE. We seek to correct this imbalance by examining works of Al-Ghazali, an early Muslim philosopher, scholar, and mystic. His approach to Sufism, combining an interpretation of revelation (...) with reason, can contribute to new developments in business ethics scholarship and practice especially in Muslim communities. His thought portrays a vibrant work ethic that, while based in Sufism, has important practical implications for business. We argue that including such historically and contextually recognized perspectives in our understanding of BE, both in theory and in practice, would work well with an audience that looks to Islam as a source of justice and proper moral conduct.

ABSTRACT An ethical analysis of Jordan's Clinical Research Law, which became effective in 2001, was performed. Accordingly, this paper discusses the major components, key strengths and weaknesses of this law. As an initial effort, the Law addresses important aspects of research ethics and, hence, should serve as an example for other Arab Countries in the Middle East. Unique aspects of the Law include the requirement that those conducting any study have insurance that can compensate for research injuries and a system (...) of fines and punishments for noncompliance with the Law. There are, however, some key items missing in the Jordanian Law. For example, the Law does not mention the requirement of a favourable assessment of risks and benefits, the fair selection of subjects, or articles regarding the protection of the rights and welfare of children and other vulnerable subjects participating in research. The paper concludes with the suggestion that new amendments should be considered for future revisions of the Clinical Research Law in Jordan. (shrink)

Research exploring how students develop their perspectives on religious moderation through reading and understanding the Qur’an is underexplored. This study aims to investigate students’ religious literacy tenet as a process of constructing meaning about religious moderation from the verses of the Qur’an. The participants involved were three students with an excellent ability to read the Qur’an and who had a great interest in the study of the Qur’an. The data were collected through the process of reading the verses of the (...) Qur’an and its textual and contextual translation. The results of this study indicate that students with high translation amendments tend to have more ability to interpret the verses of the Qur’an widely as a form of verbalisation of thoughts.Contribution: This study provides clarification on student interactions, the interpretation process and the construction of the meaning of the verses of the Qur’an. Furthermore, the results of this study encourage lecturers to reconstruct the process of learning to read the Qur’an at the university level. (shrink)

This article begins with the premise that market-oriented development strategies require more than the free movement of the factors of production from one use to another; they also require a positive work ethic and an energetic and committed workforce. However, the existing Arab work ethic does not seem conducive to␣development and change. This article assesses some antecedents that might have led to the emergence of the existing work ethic. First, we address the potential role of religion in developing a value (...) system that is not conducive to growth and development. We also tackle family dynamics in the Arab world and the impact of family structures on personal and group development. Then, we move our attention to the educational system in the Arab world trying to uncover any common patterns in the various educational approaches in the Arab world that could have had lasting impressions on power dynamics in␣Arab societies. We also address power and leadership relationships and focus our attention on how groups actually function in the Arab world. Thereafter, we tackle what has emerged out of these societal institutions and relationships, and offer some implications marking out paths for international managers. (shrink)

What and how to teach religious moderation at the undergraduate level still concerns academics. This study aims to explore the perceptions of lecturers and students about the objectives, content, and strategies used in learning religious moderation. This study uses a multiple-case exploratory design with a qualitative approach. Data were collected through interviews with eight lecturers and 15 students from public and Islamic universities in Indonesia. Data analysis in this study used conventional content analysis methods with an inductive coding process. The (...) first two authors analysed data, and their agreement was calculated using Cohen’s kappa of 0.90. As a result, participants said that the ultimate goal of learning moderation in religion is to teach students about aligning views on religion and non-religion. The content that needs to be taught early and as a firm root of religious moderation is the internal harmony of religious communities. Finally, the development of campus culture can be an alternative model to internalise the values of religious moderation. Contribution: Overall, this research helps us to understand what kind of religious moderation learning we want to introduce in Indonesian universities. (shrink)

This paper undertakes an in-depth examination of the intriguing argument for the existential import of negative propositions by the fifteenth-century Ottoman scholar Hatibzâde Mehmed (d. 1496) and the counterarguments by his disciple, Taşköprizâde Kâsım (d. 1513). It argues that this discussion is a significant example of Ottoman scholars engaging in long-standing disputes concerning the nature and ontological ground of negative propositions, which date back to Plato and Aristotle. It is also intended to underline the need for considering not only logic (...) texts but also works primarily associated with other disciplines in order to attain a comprehensive picture of logical discussions in the post-classical period of Islamic thought.

ABSTRACT:We examine the practice of nepotism in the Arab World and analyze how a rational-legal model of bureaucracy was never able to take hold. We draw upon ideas from institutional theory and related notions of legitimacy to provide an explanation of nepotism’s extraordinary persistence. Then we use arguments to speculate how the appearance of institutional entrepreneurs who are advocates for a new hybrid form of nepotism might begin to colonize a social space created by larger political and economic changes that (...) are sweeping the Arab World. Those entrepreneurs must persuade other members of an extended family that the current practice of nepotism is typically destructive of a firm’s competitive performance. In addition, they will argue that nepotism as currently practiced violates teachings of Islam. This second argument is likely to be particularly effective with an audience that sees Islam as a source of universal notions of justice and fairness. (shrink)

It is a common intuition in scientific practice that positive instances confirm. This confirmation, at least based purely on syntactic considerations, is what Nelson Goodman’s ‘Grue Problem’, and more generally the ‘New Riddle’ of Induction, attempt to defeat. One treatment of the Grue Problem has been made along Bayesian lines, wherein the riddle reduces to a question of probability assignments. In this paper, I consider this so-called Bayesian Grue Problem and evaluate how one might proffer a solution to this problem (...) utilizing what I call a phenomenological approach. I argue that this approach to the problem can be successful on the Bayesian framework. (shrink)

The purpose of this paper is to determine whether there is a relationship between a person's degree of religiousness and corporate social responsibility orientation. A total of 411 managers and 506 students from seven universities were surveyed. The statistical analysis showed that religiousness does influence students' orientation toward the economic, ethical, and philanthropic responsibilities of business. It does not, however, have a significant impact upon the managers' attitudes. When the "low religiousness" students and managers were compared, differences were found with (...) respect to the economic, ethical, and philanthropic components of corporate social responsibility. Similar results were obtained when the "high religiousness" students and managers were compared. The implications of these findings are discussed. (shrink)

There are several challenges associated with traditional business ethics education. While case studies have been used extensively in ethics education, such use can be complemented by using Problem Based Learning (PBL). PBL represents a pedagogy employing more collaborative tools that involve students more extensively in the learning process. A well-designed teaching approach based on PBL can have significant positive impact on students’ learning. This paper supplies a representative teaching interaction based on PBL, and discusses the implications of its structure. Introducing (...) PBL is challenging and comes with significant costs as faculty members have to be trained, roles have to be exchanged, powers have to be relinquished, and learning materials have tobe written. We conclude that PBL is suitable for an ethics course as most ethical situations require introspection, reflection, discovery, and concern for other viewpoints, all of which can be facilitated in a PBL environment.

This paper explores attitudes regarding tax evasion and the relationship between personal moral philosophy and such attitudes in a weak tax environment. The results confirm the multidimensionality of tax evasion attitudes. Idealism was negatively related to self-interest tax evasion attitudes while relativism was positively related to such attitudes. Idealism was also positively related to tax evasion attitudes stemming from concerns about the justice of the tax system. Idealists in a weak tax environment seemingly go through a cognitive reframing process where (...) they recognize that the tax system is unfair, and accordingly tax evasion is a way to serve a different moral absolute, that is of equity, rather than another different moral absolute, which is fulfilling obligations to governments. The results are also explained in light of the suggested low moral intensity of tax evasion among respondents. Policy implications are presented. (shrink)

Mobility is becoming a defining feature of today’s globalising society. Individuals move for a variety of reasons, including finding employment or pursuing education. This paper focuses on the interrelationship between two different types of migrants who have all moved out of one specific country to another. It builds on the perceptions of Turkish graduates of German universities who moved cross-border recently to study in German universities, the self-styled ‘New Wave Turks’, to understand their place within the existing Turkish diaspora there. (...) Although the existing Turkish diaspora in Germany is well researched, as is how diasporas can facilitate further mobility, the interaction between these newcomers and the existing Turkish diaspora in Germany has received little scholarly attention. Through in-depth semi-structured interviews with recent Turkish graduates of German universities, we explored how the existing diaspora provides support but also challenges for the newcomers, complicating their experiences. We argue that international student mobility led to the emergence of a new form of ‘total diaspora’ in Germany, comprising both the existing Turkish diaspora and newly joined Turkish graduates of German universities. Social media was instrumental for these newcomers in setting themselves apart within the total diaspora, allowing them to create their own community identity. (shrink)

A long tradition suggests a fundamental distinction between situations of risk, where true objective probabilities are known, and unmeasurable uncertainties where no such probabilities are given. This distinction can be captured in a Bayesian model where uncertainty is represented by the agent’s subjective belief over the parameter governing future income streams. Whether uncertainty reduces to ordinary risk depends on the agent’s ability to smooth consumption. Uncertainty can have a major behavioral and economic impact, including precautionary behavior that may appear overly (...) conservative to an outside observer. We argue that one of the main characteristics of uncertain beliefs is that they are not empirical, in the sense that they cannot be objectively tested to determine whether they are right or wrong. This can confound empirical methods that assume rational expectations. (shrink)

This paper is an evaluation and expansion of William Hasker’s transcendental argument against determinism. Hasker’s argument attempts to show that determinism is logically incompatible with rationality and justified belief. Hasker claims this argument to be conclusive given two independent qualifications: first that the argument only applies to a specific form of determinism, and second that the argument rests on a specific conception of rationality. My aim in this paper will be to modify and expand Hasker’s argument such that it (1) (...) applies to the more general deterministic thesis (as defined below), and (2), rests on a modified epistemic conception of rationally unaffirmable beliefs. I will attempt to do (2) by modeling Hasker’s argument after one of Alvin Plantinga’s epistemological arguments against naturalism, and hope to show that such an argumentative model is superior for the conclusion Hasker wishes to bring out. I will begin by explicating Hasker’s argument, and then I will move to the modification and expansion of the argument. (shrink)

The Sufyānī narration, which is also referred in some studies carried out today, is mentioned in the early Shiite and Sunnī sources. The anticipated savior perception of the period has an important place in understanding the Sufyānī narrations in the emergence process of which political and sectarian events were effective. Narrations stating that the Mahdī named Muḥammad, one of the descendants of the Prophet Muḥammad (pbuh), would appear in the end of times and establish justice by bringing order to the (...) world where oppression, injustice and inequity have spread, were effective in the political and social life after the Prophet (pbuh). The emergence of the Sufyānī narrations, whose intellectual infrastructure was constituted by the expected Mahdī perception that is effective in the society, was the result of the political conflicts of the period. The death of Muʻāwiya ibn Yazīd (d. 64/684), the third Caliph of the Umayyad State, without leaving a crown behind caused a political crisis. The cousin of the Muʻāwiya II, Marwān bin al-Ḥakam, the experienced politician who turned this moment of crisis into an opportunity and who was from the same dynasty but from a different family, took over the administration and thus the sultanate continued. Although the reign continued from the sons of Umayyad, the administration passed from sons of Sufyān to the sons of Marwān, who were from the same dynasty. This situation caused discomfort in Sufyānīs. Thus, Muʻāwiya II's brother Khālid ibn Yazīd, whose right of administration was seized from him, with the intention of gaining his lost reputation in the society and turning the pessimism towards his family into hope and desire, has been claimed to spread the savior Sufyānī narrations expected from the sons of Sufyān, parallel to the Mahdī narrations expected from the sons of Alī, which was influential in the society. Thus, the Sufyānī came to be expected like the expected Mahdī, who was influential in society and exploited by the Shiite sects in their own belief systems. The rebellions carried out by the sons of Sufyān against the administration in the 2nd century hijrī and afterwards were conceived as the appearance of the Sufyānī expected by the society and the person who led the rebellion was described as Sufyānī. The most important of these rebellions is the revolt of ʻAlī ibn Abdullah ibn Khālid nicknamed Abū ʻAmayṭar, formed by the coalition of sons of ʻAlī and sons of Sufyān who descend from the sons of Umayya. Abū ʻAmayṭar, who is considered to be the Sufyānī and some sections of whose life constitute a source for many narrations on the Sufyānī, declared his caliphate during the period of Abbasī Caliph al-Amīn (d. 198/813) and called for allegiance to himself. The announcement of his caliphate was considered by his supporters as the expected savior. The period of Abū ʻAmayṭar and the sayings about him are extremely important in terms of presenting the expected savior perception in the society, the Sufyānī understanding and the date of his emergence. Sections from Abū ʻAmayṭar's life reflected in the narrations about the Sufyānī in many Shiite and Sunnī sources. In this article, it is tried to examine the emergence of the Sufyānī narrations, its development and particularly its transformation within the Shiite sect, in a detailed manner and especially based on political and sectarian events of the early period.

We provide a simple model to measure the impact of aggregate risks. We consider agents whose rankings of lotteries over vectors of outcomes satisfy expected utility and separability. Such rankings are characterized in terms of aggregative utilities that measure sensitivity to aggregate uncertainty in a straightforward way.

The framework lends support to precautionary measures that penalize policies for exposure to correlation. The model rationalizes a (...) number of behavioral and policy patterns as attempts to hedge against aggregate uncertainty. (shrink)
