Online forums have become the main source of knowledge over the Internet as data are constantly flooded into them. In most cases, a question in a web forum receives several responses, making it impossible for the question poster to obtain the most suitable answer. Thus, an important problem is how to automatically extract the most appropriate and high-quality answers in a thread. Prior studies have used different combinations of both lexical and nonlexical features to retrieve the most relevant answers from (...) discussion forums, and hence, there is no standard/general set of features that could be effectively used for relevant answer/reply post classification. However, this study proposed an answer detection model that is exclusively relying on lexical features and employs a random forest classifier for classification of answers in discussion boards. Experimental results showed that the proposed answer detection model outperformed the baseline technique and other state-of-the-art machine learning algorithms in terms of classification accuracy on benchmark forum datasets.

The article investigates the development of discourses related to freedom of religion and discrimination against religious minority in current Indonesia by identifying the discourse constructions of Ahmadiyya in various texts and talks produced and disseminated by government institution and the Indonesian Council of Ulama (the MUI). This study aims to reveal these institutions’ views and perspectives on Ahmadiyya issue using various discourse strategies. The data analysed are some legal proclamations issued and personal views delivered by the officials of these two (...) institutions. The CDA theoretical framework employed is to examine the positive-self and negative-other presentations. The finding reveals that the issue of Ahmadiyya is addressed through discourses related to Indonesian national interest and discourses related to religious matters. in these discourses, the two institutions and their officials present themselves positively and portray the Ahmadiyya sect negatively. The sect followers are negatively presented as the troublemaker, blasphemer, and the destroyer of religious harmony and social order. (shrink)

History in this age needs to record and analyze the events in the light of modern concept of contemporary world. When the historians narrate the brutal condition of Indo-Pak history, they never forget the work and services of Shaykh Ahmad Sirhindi to transform the society according to the current values. For his services, he is hailed as Mujaddid Alf-I-Thani. The Muslim society had degenerated when Mujaddid Alf-I-Thani appeared on the horizon. A number of Hindu customs and practices had become the (...) part of their creed. The commandments of Shariat and Sunnah were being floated. Moreover, the Mughal emperor Akbar had adopted controversial policies detrimental to the very existence of Muslim society. Mujaddid Alf -Thani made strenuous and constant efforts to turn the tide. When Mujadded-Alf-Thani started his social reform movement, he found that the Muslim society was embracing un-Islamic practices such as widespread belief in Karamat had developed under the influence of Hindu thinking. Moreover, the Islamic teachings had been vitiated by adopting customs and practices of other religions such as inter marriages between Hindus and Muslims and ban on cow slaughter etc. Shaykh Ahmad Sirhindi never entered into any political conflict directly. He endeavored to restore pure doctrine to Islamic thought and to compel the Muslims to follow Shariat and Sunnah in letter and spirit. He was a social reformer, great Alim, Sufi and Mujaddid. He initiated a process of social change, inspired by Islamic Ideal, in an age, which was becoming secular. This research paper is an attempt to mention the role of Shaykh Ahmad Sirhindi for saving the society from un-Islamic values and customs in the sub-continent and its impact on society. By utilizing the historical method, this paper aims at analyzing the effect of social reforms of Shaykh Ahmed Sirhindi on Muslim society. (shrink)

This study explores the impact of CEO ability on corporate environmental sustainability information disclosure. We take samples from Chinese A-share listed companies from 2010 to 2019 and use the ordinary least squares as a baseline regression model to check the relationship between CEO ability and corporate environmental sustainability information disclosure. Our findings are robust to different corporate environmental sustainability information disclosure measures and CEO ability. We found a positive association between CEO ability and corporate environmental sustainability information disclosure; thus, firms (...) with a more able CEO are more likely to disclose more corporate environmental sustainability information. Our results also found a significant negative interaction coefficient between CEO ability and CEO career concerns. As the CEO grows older, his/her ability decreases; therefore, corporate environmental sustainability information disclosure reduces. Furthermore, we document that a female CEO strengthens the relationship between CEO ability and corporate environmental sustainability information disclosure. The study results are important for understanding corporate environmental responsibility development and implementation, particularly in China. (shrink)

In step with rapid advancements in computer vision, vehicle classification demonstrates a considerable potential to reshape intelligent transportation systems. In the last couple of decades, image processing and pattern recognition-based vehicle classification systems have been used to improve the effectiveness of automated highway toll collection and traffic monitoring systems. However, these methods are trained on limited handcrafted features extracted from small datasets, which do not cater the real-time road traffic conditions. Deep learning-based classification systems have been proposed to incorporate the (...) above-mentioned issues in traditional methods. However, convolutional neural networks require piles of data including noise, weather, and illumination factors to ensure robustness in real-time applications. Moreover, there is no generalized dataset available to validate the efficacy of vehicle classification systems. To overcome these issues, we propose a convolutional neural network-based vehicle classification system to improve robustness of vehicle classification in real-time applications. We present a vehicle dataset comprising of 10,000 images categorized into six-common vehicle classes considering adverse illuminous conditions to achieve robustness in real-time vehicle classification systems. Initially, pretrained AlexNet, GoogleNet, Inception-v3, VGG, and ResNet are fine-tuned on self-constructed vehicle dataset to evaluate their performance in terms of accuracy and convergence. Based on better performance, ResNet architecture is further improved by adding a new classification block in the network. To ensure generalization, we fine-tuned the network on the public VeRi dataset containing 50,000 images, which have been categorized into six vehicle classes. Finally, a comparison study has been carried out between the proposed and existing vehicle classification methods to evaluate the effectiveness of the proposed vehicle classification system. Consequently, our proposed system achieved 99.68%, 99.65%, and 99.56% accuracy, precision, and F1-score on our self-constructed dataset. (shrink)

Unmanned aerial vehicles, particularly quadcopters, have several medical, agriculture, surveillance, and security applications. However, the use of this innovative technology for civilian applications is still very limited in low-income countries due to the high cost, whereas low-cost controllers available in the market are often tuned using the hit and trial approach and are limited for specific applications. This paper addresses this issue and presents a novel proof of concept low-cost quadcopter UAV design approach using a systematic Model-Based Design method for (...) mathematical modeling, simulation, real-time testing, and prototyping. The quadcopter dynamic model is developed, and controllers are designed using Proportional Integral, and Derivative, Pole Placement, and Linear Quadratic Regulator control strategies. The stability of the controllers is also checked using Lyapunov stability analysis. For verification and validation of the design, Software-in-the-Loop, Processor-in-the-Loop, Hardware-in-the-loop testing, and Rapid Control Prototyping have been performed. The V&V methods of the MBD approach showed practically valid results with a stable flight of the quadcopter prototype. The proposed low-cost POC quadcopter design approach can be easily modified to have enhanced features, and quadcopters with different design parameters can be assembled using this approach for a diverse range of applications.

Seasonal outbreaks have several different periods that occur primarily during winter in temperate regions, while influenza may occur throughout the year in tropical regions, triggering outbreaks more irregularly. Similarly, dengue occurs in the star of the rainy season in early May and reaches its peak in late June. Dengue and flu brought an impact on various countries in the years 2017–2019 and streaming Twitter data reveals the status of dengue and flu outbreaks in the most affected regions. This research work (...) presents that Social Media Analysis can be used as a detector of the epidemic outbreak and to understand the sentiment of social media users regarding various diseases. Providing awareness about seasonal outbreaks through SMA is an effective approach for researchers and healthcare responders to detect the early outbreaks. The proposed model aims to find the sentiment about the disease in tweets, and the seasonal outbreaks-related tweets are classified into two classes as disease positive and disease negative. This work proposes a machine-learning-based approach to detect dengue and flu outbreaks in social media platform Twitter, using four machine learning algorithms: Random Forest, K-Nearest Neighbor, Support Vector Machine, and Decision Tree, with the help of Term Frequency and Inverse Document Frequency. For experimental analysis, two datasets are analyzed individually. The experimental results show that the RF classifier has outperformed the comparison models in terms of improved accuracy, precision, recall, F1-measure, and Receiver Operating Characteristic curve. The proposed work offers favorable performance with total precision, accuracy, recall, and F1-measure ranging from 84% to 88% for conventional machine learning techniques. (shrink)

A complete classification of simple function germs with respect to Lipschitz equivalence over the field of complex numbers ℂ was given by Nguyen et al. The aim of this article is to implement a classifier in terms of easy computable invariants to compute the type of the Lipschitz simple function germs without computing the normal form in the computer algebra system Singular.

In computer networks, vertices represent hosts or servers, and edges represent as the connecting medium between them. In localization, some special vertices are selected to locate the position of all vertices in a computer network. If an arbitrary vertex stopped working and selected vertices still remain the resolving set, then the chosen set is called as the fault-tolerant resolving set. The least number of vertices in such resolving sets is called the fault-tolerant metric dimension of the network. Because of the (...) variety of applications of the metric dimension in different areas of sciences, many generalizations were proposed, and fault tolerant is one of them. In this paper, we computed the fault-tolerant metric dimension of triangular snake, ladder, Mobius ladder, and hexagonal ladder networks. It is important to observe that, in all these classes of networks, the fault-tolerant metric dimension and metric dimension differ by 1. (shrink)

Topological indices are quantitative measurements that describe a molecule’s topology and are quantified from the molecule’s graphical representation. The significance of topological indices is linked to their use in QSPR/QSAR modelling as descriptors. Mathematical associations between a particular molecular or biological activity and one or several biochemical and/or molecular structural features are QSPRs and QSARs. In this paper, we give explicit expressions of two recently defined novel ev-degree- and ve-degree-based topological indices of two classes of benzenoid, namely, linear hexagonal chain (...) and hammer-like benzenoid.

Also, we determine all the trees of order n (...) with given diameter d and having first three largest values of the SEI a index. (shrink)

Business Ethics, the Environment & Responsibility, EarlyView.

According to Abrahamic religions, namely Judaism, Christianity and Islam, human beings exist on the earth for a common purpose, and they have patrilineally and matrilineally descended from a single couple, namely Adam and Hawa (Eve). The Qur’an unambiguously mentions: “O mankind! reverence your Guardian-Lord, who created you from a single person, created, of like nature, His mate, and from them twain scattered (like seeds) countless men and women; reverence Allah, through whom ye demand your mutual (rights), and (reverence) the wombs (...) (That bore you): for Allah ever watches over you.” Thus, it is incumbent upon human beings to live together in peace rather than constant hostility to fulfil the purpose of their existence on the earth. This paper endeavours to contribute to the understanding of the concept of ‘peaceful coexistence’ from the Islamic perspective. It specifically answers the following research questions: What is peaceful coexistence? What is necessary for peaceful coexistence? What are the fundamental principles that we must adhere to in order to coexist peacefully? The paper is structured into eight sections, beginning with introduction on the concept of ‘peace’ in Islam. The second section focuses on the main objectives of Islam. The third section is on the meaning of peaceful coexistence. The fourth and fifth sections are on the need for peaceful coexistence, and the necessary requirements and tools for peaceful coexistence respectively. The sixth section is on categorization of peaceful coexistence into: peaceful coexistence in marriage, peaceful coexistence of mankind, peaceful coexistence of the members of the Muslim ummah and peaceful coexistence of mankind and the environment. The seventh section is a summary of the Islamic principles of peaceful coexistence. The final section sums up the main conclusions drawn from this study. The translation of the ayat (verses) of the Qur’an related to this study is extracted from the work of Abdullah Yusuf Ali, The Holy Qur’an: Text and Translation unless stated otherwise. At the end of this paper, it is hoped that the readers will: first, appreciate the message of Islam as a universal religion and the need for mutual care, mutual respect, and mutual cooperation; and second, explore the methodology of the Qur’an and the Prophet Muhammad (peace and blessings be upon him) in managing human diversity. It is also hoped that this study will lead to a better understanding of peaceful coexistence as an integral part of Islam and one of the characteristics of the Muslim ummah. The findings of this study highlight the role of Islam in promoting peace and security. The study reveals that peaceful coexistence is a key factor in the success of human beings and it requires nurturing love, respect, care, and salam (a greeting of peace) in one’s relationship with others.

The early period Ismaili jurist Al-Qādî al-Nu'mān appears as an important figure in the formation of Ismaili jurisprudence. There is very little information about Kadı Nu'mân's family, childhood, education and intellectual environment. His full name is Abû Hanîfah Nu'man b. Muhammad b. Mansûr al-Qādî at-Tamîmî Al Qayrawānî. He was born around 290/903 (late 3rd (9th) century) into an educated family in Qayravan in North Africa. There are different opinions about the sect he belonged to when he was growing up. On (...) the other hand, it is difficult to say for certain whether Nu’mān received education in the Ismaili sect due to the understanding of taqiyya in the madhhab. However, it is understood from the basic jurisprudence texts Nu’mān wrote that he most likely did not receive a Sunni education. Historians refer to him as 'Qadi Nu’mān or Abu Hanifah al-Shi'i' in order not to confuse him with the imam of the Hanafi school. Qādî Nu’mān served at different levels of the Fatimid State. Around 313/925, he entered the service of the first Fatimid caliph, Mahdi (r. 909-934 CE/297-322 AH), as a copyist and secretary. During the reigns of the third caliph Mansur and the fourth Fatimid caliph Mu’izz (d. 365/975), Qādî Nu’mān first served as a judge in Tripoli and then in Mansouriya, the Fatimid capital. After the Fatimids conquered Egypt and the center of government was moved to Cairo, Qādî Nu’mān was appointed by the fourth caliph Mu’izz as the head of the appellate courts (maẓālim). Qadi Numans career was at the peak in the period of Caliph Muiz. Qādî Nu’mān worked as a judge in the Fatimid State for about twenty-six years and continued this duty until his death in 363 (973). After the fall of the Fatimid caliphate, there haven’t been any other Fatimid or Ismaili jurists. Qādî Nu’mān is considered by contemporary Ismaili writers as a figure who systematically transformed Ismaili fiqh into an independent sect of fiqh. It can be said that Ismaili fiqh was developed through his works in the Fatimid period. His works continued as the main references in the fiqh studies and after the Fatimid period. With the death of Qādî Nu’mān, the period of ijtihad in Ismaili fiqh and its the establishment phase of Ismaili fiqh came to an end; The sect, in which esoteric interpretations were at the forefront, emerged as a distinctive school of fiqh by discarding ambiguity. Qādî Nu’mān was a very productive writer. He wrote important works related to the field of furu al-fiqh and usûl al-fiqh. Among his works, Ikhtilāf uṣūl al-madhāhib is undoubtedly one of the most important works in the early history of fiqh methodology. The work in question, which was originally written with the aim of rejecting the Sunni fiqh method, discusses the approaches of the Sunni schools of fiqh on ikhtilāf, taqlid, ijma, nazar, qiyas, istihsan, ijtihad and ra’y in a polemical manner. It reveals the differences of the Ismaili method from the Sunni method in terms of the sources on which the fiqh is based, the authority to make ijtihad and the theory of interpretation of the texts. Qādî Nu’mān examined the relationship between reason and revelation in general and the role of religious authority in comprehending and interpreting the texts while criticizing Sunni methods. Ikhtilāf uṣūl al-madhāhib has the characteristics of the works of development period as a form. It is possible to observe the question-answer and dialectic form which can be seen in the works of the development period throughout the work in question. Qādî Nu’mān endeavoured to persuade his opponents with a dialectical and argumentative style. Again, he replied to the Sunnis, who were his interlocutors, with their own proofs. In addition to these, Ikhtilāf uṣūl al-madhāhib has a unique feature in the matter of content. Because it is not very familiar to any Sunni handbook of usûl al-fiqh. It does not mention the hâss, âmm, ijma, qiyas, amir, nahy, alfaz bets, etc. The text is very similar to the Ahbari movement of the Jafari sect for it rejects all forms of ijtihad. It was written at a time when fiqh was not yet stable. Ikhtilāf uṣūl al-madhāhib gives us crucial information about the development of different usûl and fiqh sources in the middle of the fourth century. However, what is interesting here is that the information he gives about Ismaili method and fiqh is very little compared to the one about Sunni method and fiqh. Much of it centered on Sunni thought and its rejection. However, his ultimate goal was to defend the Ismaili doctrine. (shrink)

One of the most important issues that distinguishes the Baghdādī branch of the Muʿtazila from the Baṣran branch is their view on ʿAlī b. Abī Ṭālib (d. 40/661). Basra branch accepts the order of virtue of the first four caliphs as their order of coming to office, while the Baghdad branch considers the first three caliphs legitimate, but considers Ali more virtuous than them. The Baghdādī Muʿtazilīs who outspokenly defended this idea were Abū Jaʿfar al-Iskāfī (d. 240/854), Abū al-Qāsim al-Kaʿbī (...) (d. 319/931) and Ibn Abī al-Ḥadīd (d. 656/1258). Among them, Ibn Abī al-Ḥadīd was renowned as “the greatest scholar of the Muʿtazila” and was considered one of the last representatives of this school. He ardently defended ʿAlī's superiority in his commentary on Nahj al-Balāgha, the famous collection of Ali’s sermons, letters and wisdom sayings. In his defense, he rebutted some criticisms about ʿAlī’s political decisions from his school’s point of view. Many items of Ibn Abī al-Ḥadīd’s rebuttal are worthy of analysis in terms of their content, style and approach. This article aims to present a detailed account of Ibn Abī al-Ḥadīd’s aforementioned refutations. In addition to the descriptive method, the interpretative method was also employed in the article. Although Ibn Abī al-Ḥadīd did not consider Ali's infallibility necessary (wājib), unlike Imamiyya, he accepted it. Therefore, he responded to the criticisms directed at Ali, starting from the point of Ali's innocence. According to Ibn Abī al-Ḥadīd: (a) After the death of the Prophet, ʿAlī insisted on becoming the new leader of the Muslim community. He did not act hastily to assume the caliphate because he was not expecting any opposition to that. However, when the events took a different turn, he did not escalate the situation, rather accepted the status quo. (b) ʿAlī also did the right thing by participating in ʿUmar b. Al-Khaṭṭāb’s (d. 23/644) electoral shūrā. This was an opportunity for him to become the next caliph, and reinstitute a system in accordance with the Qurʿānic principles and sunna of the Prophet. (c) It was also not an error when ʿAlī decided to stay in Medina during the events of ʿUthmān’s murder (d. 35/656). He played an active role in dissuading the rebels from their attempt to kill ʿUthmān, but he was in no position to know that his activity would be used against him later by the Umayyads who accused ʿAlī of being complicit in ʿUthmāns’s murder. (d) ʿAlī took the caliphate after ʿUthmān because of his popularity among the people. In this way, he managed to prevent an unqualified person to occupy the seat of the caliphate. (e) When the Battle of Camel broke out, those who demanded justice and opposed ʿAlī were in error. (f) When ʿAlī became the new caliph, his decision to remove Muʿāwīya (d. 60/680) from the governorship of Syria was correct. This is because Muʿāwīya would have refused to accept ʿAlī’s leadership even had he stayed in office as a governor. ʿAlī understood that the conflict would end only through fighting, so he did not lose time in marching against Muʿāwīya. (g) During the battle he abided by the sharīʿa and allowed the Syrian army to access water. (h) It was not ʿAlī, but those defectors in his army who obliged him to end the fighting through arbitration. (i) When ʿAlī agreed to sign the Ṣiffīn ceasefire agreement and did not use his title amīr al-muʾminīn, he followed the Prophet's example since the latter also refrained from using his title during the Ḥudaybiyya agreement. (j) ʿAlī also cannot be blamed for those among his supporters, such as the poet al-Najāshī, who defected and joined the ranks of Muʿāwīya. The motivations for the defectors were either to attain worldly gains or to escape from punishment for the crimes which they had committed. (k) When Muʿāwīya managed to conquer Egypt, ʿAlī’s governors of the province, Qays b. Saʿd (d. 60/680) or Muḥammad b. Abī Bakr (d. 38/658), did nothing for which they could be blamed. (l) And finally, ʿAlī never had guards to protect him because he was never afraid of being assassinated. Although Ibn Abī al-Ḥadīd took Ali's innocence as a basis while presenting these views, he did not make inconsistent comments in general and did not say things contrary to historical facts. Therefore, it is necessary to acknowledge historical value of his views in question. (shrink)

Abdullāh Ibn Abbās is one of the companions well known for his verdicts in the area of the Islamic law of inheritance and the abundance of his verdicts in jurisprudence. In this regard, the inheritance sections of the jurisprudence books often include Ibn Abbās's verdicts and applications. He approached the matters regarding jurisprudence from a different perspective, ruled differently from the companions, and provided corrections mainly in terms of the science of inheritance regarding the sayings narrated by the companions, applications and verdicts of the companions. In this regard, Ibn Abbās considered the jurisprudential aspects of the sayings and applications of Prophet Muhammad and made a ruling by interpreting the same narration by his wide understanding and knowledge and considering the meaning of the sayings. Ibn Abbās, who made different interpretations and evaluations in his corrections regarding the law of inheritance, objected to Umar Ibn Al-Khattab and Uthman Ibn Affan, criticized and corrected the narrations of Zayd Ibn Thabit. Ibn Abbās, who interpreted the matters regarding inheritance according to the principles of the Qur'ān, made rulings according to the apparent meanings of the related verses of the Qur'ān. (shrink)

Qutayba ibn Muslim al-Bāhilī is one of the leading soldier-bureaucrats of the Umayyads period. During the time he served as the governor of Khurāsān, he consolidated the Umayyad’s rule in Tokharistan and Transoxiana provinces, and expanded the borders of the state to China by conquering the Kashgar region. His activities for conversion of the people of the conquered regions have great importance in the history of Islam since the intense relations of the Turkish people with Islam fell upon the time (...) of his governorship. It is possible to argue that by introducing the religion to these people Qutayba had played an important role in their conversion to Islam. It is also known that he had sent a delegation to the emperor of China for the same purpose. However, despite all his achievements, it is seen that the academic studies about Qutayba in our country are very rare. Besides, some of the recent studies about him claim that he was a fraud, a trickster, and an untrustworthy person in his military activities; and had committed mass murders and massacres, persecuted innocent people, destroyed and burned the cities of conquered lands. In this article, it is examined that whether these claims and accusations have their justifications or not by consulting the main sources. In fact, what is expected from constructive criticism in this subject and every other area is to clarify the matter and make it more comprehensible of its context. However, it should not be forgotten that some conclusions over Qutayba in these studies might have been drawn to quickly in order to manipulate the conquest movements of the Umayyad period.Summary: The religious interaction and change taken place in the Arabian Peninsula with the emergence of Islam and with the political, military and cultural activities of the Muslims performed during the periods of Prophet Muhammad and the Rāshidūn (rightly guided) Caliphs had significant effects upon the lands of Iraq, Syria, Egypt and Khurāsān where the ancient civilizations located.The success made by the Muslim-Arabs in such a short time is accepted of course as one of the important events of world history. The message of Islam spread rapidly with their extraordinary efforts, and reached quickly in the early days of Islam to the Amu Darya/Oxus River, which is considered to be the natural border between the Iranians and the Turks (Iran and Turan).Although the Turks who had been struggling to dominate the region for centuries gained an opportunity with the disappearance of the Sasanian Empire from history, they could not take advantage of this new situation because of their lack of political unity and a strong state, and the power held by the regional Turkish Sultans were not enough to make their dominance happen. In this conjuncture, the Muslim-Arabs who appeared in the stage of history in a relatively late period but had the ideal of being a regional and a global power had rapidly realised their political and military activities called “conquest” in the Islamic historical sources. When it comes to the period of Caliph ʿUthmān, it is seen that the conditions were very suitable for passing to the east of the Oxus River where the Turkish elements lived intensively. At the time, the absence of a strong Turkish state in the region, and China’s occupation with its own internal problems made an important contribution for the Muslim-Arab capture of the region. In this region, which is called as “Transoxiana” in the Arabic sources, it is seen that the Turks organized their political structures as city-states and regional sultanates. In the north-eastern parts of this region, there was a strong Turkish State called the Turgish State and it provided political and military support to the people of the region who rebelled occasionally the Umayyads.After solving the internal problems of the state largely and suppressing some dangerous revolts, the Umayyad Caliph ʿAbd al-Malik ibn Marwān became capable of initiating military activities beyond the borders of the state. Nevertheless, the period when the actual conquests were made was the period of his son Walīd (86/705-96/715). It is seen that the conquests made in his time were permanent, and the people who lived in the conquered lands accepted Islam to a large extent. The conquest made during Walīd’s time which extended from Kashgar to the Pyrenees, realised at an unprecedented pace. The most important name for the eastern side of the conquests is undoubtedly Al-Ḥajjāj ibn Yūsuf. Ḥajjāj (75/694-95/714) who acted as the supreme governor of Iraq for nearly twenty years, had achieved important successes in the regions of Transoxiana and Sindh located in the eastern part of the country by the hands of his appointed governors. However, many governors appointed by him to Khurāsān from 75/694 to 86/705 with the hope of reaching his goals in the east could not meet his expectations because of the political, social and economic problems that existed throughout the country, and because of the resulting rebellions in the regions that these problems caused.These unwanted conditions continued to be seen in the region until he appointed Qutayba ibn Muslim as the governor of Khurāsān (86 / 705-96 / 715) who was one of the young commanders and administrators educated by Ḥajjāj personally. Qutayba known as having a close relationship with Ḥajjāj and consulting him when taking important decisions acted in this direction throughout the time he stayed in this position.It is known that the internal conflicts in the region continued during the time when Qutayba was appointed as the governor of Khurāsān. However, he had brought together northern and southern Arabian tribes living in the region with religious, political and economical suggestions and had succeeded in persuading them for military activities that he decided to operate beyond the Oxus. For the Umayyads, these military operations were justified, because the regional sultans who ruled in the western and eastern sides of the Oxus repeatedly violated the agreements they had made before. The tendency of the people of Turkic, Iranian, and Tajik origin who were the real owner of these lands and lived in both sides of the rich Oxus basin for many centuries to violate these agreements was in fact result of a great concern. They now realized that the Muslim-Arabs who followed a systematic settlement policy in the region came to their lands this time without any intention of going back. Even though Qutayba followed a fair and reasonable policy towards them, they violated their agreements with him, formed alliances among themselves and waged military campaigns against Qutayba not to be the subjects of any change in their religion, worldview, and perception of existence.Qutayba, who is believed to have spent his its utmost efforts to make the religion of Islam and the Umayyad political cause permanent in the region under these unfavourable conditions, has been recently criticized by some researchers. The criticisms intensify around the claims that he persecuted people, committed massacres, and behaved unfaithfully by breaking his promises that he made with people. From the perspective of our own times, it is possible to think that sometimes he had taken extreme measures in punishing the sultans and the persons who raised armed struggles against him and caused riots by violating the agreements. However, when the period is compared with the others, it can be easily said that the Umayyads showed in these and other remote areas a considerable amount of tolerance that they had never shown it in their internal conflicts. It is a known fact that he generally clashed with the ones who disrupted agreements, sought help from external forces, established alliances against them, and refused to pay taxes. Based on historical sources, it does not seem to be possible to say that while doing these activities in the region, Qutabya did not behave entirely in a way that his behaviour could be classified as massacres committed against innocent civilians. On the contrary, it is known that Qutayba had given many chances to the people of the region in administrative and military affairs. As a matter of fact, he ruled the city of Bukhara for 20 years with a Turkish ruler whom he appointed and supported, and he included in his army a union of twenty thousand cosmopolitan soldiers assembled from the people of Bukhara, Baykend, Chach and Samarkand and paid a regular salary to them.The fact that his grave known as the “Imam Shaykh Qutayba Tomb” was turned later into a shrine and visited by the people even today despite the passage of long centuries after his death shows that he has been loved by the people of the region and that they have always considered him as a conqueror-bureaucrat who spent his life for the ideals of his religion.

Dede Korkut Stories are a national cultural heritage that narrates about events and challenges of Oghuz Turks in 10th-11th centuries. This period of time is important, as it was the times when Turks became Muslims. In this work, heroism, customs, habits and traditions, socio-cultural and moral life of the Turks before and after becoming Muslims are analysed. One of the topics addressed in this work is religious beliefs and worships of the Turks after became Muslims. In this context, the belief (...) in Allah appears to be the most emphasized type of belief in the stories. The theme of fate, which is included in the subjects of Tawḥīd (oneness of Allāh) is another theme mentioned in the stories. The stories also includes some expressions regarding particularly the Prophet Muḥammad as well as some other prophets. Jibrīl and ʿAzrāʾīl angels are also mentioned. As for the Divine Books, only the Qur’ān is namely addressed and other divine books are not mentioned. The beliefs regarding afterlife, such as death, resurrection, heaven, hell, pool of al-Kawthar (abundance) are also referred to in the stories. The Book of Dede Korkut is not a didactic work written to teach Islam. On the contrary, in the stories, Islam is discussed as an element of the spirit/essence of individual and society. The aim of this study is to investigate the representations of the beliefs of tawḥīd, prophecy and hereafter of the Turks, especially the Oghuz Turks with reference to narrations in Dede Korkut stories. It aims to discuss them in the context of six pillars of faith and evaluate from the Islamic belief point of view.Summary: The Book of Dede Korkut consists of twelve epic stories created within the oral tradition of Turkish Folk Literature. It is said that the origins of these stories, which are one of the oldest works of Turkish Folk Literature, went as far as 7th century. It is generally accepted that the Book of Dede Korkut, which narrates about Oghuz Turks who lived in 10th-11th centuries was transferred to writing after 15th century. There is no information found about writer/s of the Book. Dede Korkut, who considered being the narrator of the stories, is in fact a character in the stories. Dede Korkut plays qobuz, reads poetry, names children, mediates in marital affairs, resolves disputes, and leads religious rituals in the stories. Therefore, he stands out as a saint figure and considered to be wise man of the Oghuz Turks in almost every story, especially regarding social events. In this work, there are many expressions about heroism, customs, habits and traditions, socio-cultural and moral experiences of the Turks before and after becoming Muslims. The stories bear many traces from the earlier Turkish beliefs. However, these are not the issues of this study. The dates of the emergence of the stories, 10th and 11th centuries, coincides with the times when the Turks became Muslim. This situation makes the stories more important as they include rich narratives about the fundamental beliefs of Islam. Especially the belief in Allāh, which is one of the six pillars of faith, appears to be the most emphasized in the stories. In these stories, Turkish and Persian names of Allāh as well as His Arabic names and attributes are mentioned directly or indirectly.The belief in predestination and casualty related with Allāh's eternal knowledge and determination is another faith object that takes place in the stories. The issues regarding the predestination discussed in the stories as follows: the deeds occur with the wish of Allāh; Allāh decides whether the child male or female; Allāh predestines human lifetime, livelihood, time of death and calamities.There are also narrations about the belief in the prophets in the stories. Particularly the Prophet Muhammad's prophecy is prioritised. Adam, Noah, Abraham, and Moses are the other prophets mentioned in the stories. The successive authority of Adam and His story with Iblīs; the wife and donkey of Noah, not burning of Abraham when he was thrown into the fire, the speaking of Allāh with Moses and the staff of Moses are some of the expressions related with prophecy in the stories. Nimrod against Abraham and Pharaoh against Moses are described as negative personalities in the stories. In the stories, the Prophet Muhammad (pbuh) is handled in a position that intercession is demanded from Him. Greetings and prayers are read for Him. His intercession is sought for forgiveness of sins and acceptance of prayers. He is exalted with some attributions, such as the holly Prophet Peace be upon Him, friend of Allāh, the leader of religion and the headman of religion. When the Prophet Muhammad is mentioned, it is felt that there is a high respect and an enthusiastic love. When he is addressed, the expressions indicating respect and affection, such as "His name is magnificent Muhammad" and "His name is magnificent Muhammad Mustafa" are used in the stories.In the stories, only the Qur’ān is mentioned among the divine books, none of the Torah, the Zabūr and the Injīl is mentioned. It is referred that the Qur’ān descended from the heavens and it is the word of Allāh and His knowledge, and it was copied (collected) by Uthman. It is described as "Magnificent Qur’ān".It is seen in the stories that there is also a place for the belief in angels and only two of the four great angels are mentioned. One of them is ʿAzrāʾīl, the death angel. It is one of the main heroes in the story of Deli Dumrul. ʿAzrāʾīl is described as an angel from the sky, who has red-winged, who takes the souls of living beings by the command of Allāh and kill them. It is also narrated that ʿAzrāʾīl takes the form of human and pigeon, and the struggle of ʿAzrāʾīl with Deli Dumrul. The other great angel mentioned in the stories is Jibrīl. In the story of Emre, the Son of Begil, it is described as an angel fulfilling the commandments of Allāh. Apart from these, there is no information about other angels and their characteristics, such as not being gendered, not to sin, and being created from light. Within the scope of invisible beings, the Devil is also narrated in the stories as it did not prostrate itself to Adam, and therefore it was repelled and cursed.The principle of the belief in Hereafter, which is one of the pillars of faith, is also dealt with in the stories. The ending, death, resurrection, reckoning, Heaven, Hell, seeing Allāh's face in Heaven, drinking water from the pool of al-Kawthar are some of the topics addressed in relation to this principle. While talking about Heaven in the stories, the words "Uçmak" (flight) in Turkish and "Behesht" (paradise) in Persian are mentioned in addition to Arabic "Jannah" (heaven).The Book of Dede Korkut is not a religious book written to teach the ʿaqāʾid (beliefs) of Islam or its practices. On the contrary, it is a work that narrates about people’s lives and social experiences. There is neither any specific verse from the Qur’ān nor sayings or the deeds of the Prophet (ḥadīth) included in the stories. However, the contents of many issues stated in the Qur’ān and ḥadīth are expressed in the stories. For instance, the statements from the surah (chapter) al-Ikhlāṣ (sincerity), such as al-Aḥad (the one), Allāh begets not, nor was He begotten, and not being any equivalent to Him are mentioned in the stories. Likewise, not burning of the Prophet Abraham when thrown into the fire, speaking of Allāh with Moses and giving the stuff to him as a miracle are also stated in the Qur’ān. As for the pool of al-Kawthar, the believers’ seeing Allāh in Heaven, ineffectiveness of the deeds without saying in the name of Allah are mentioned in ḥadīths. However, some information that is not rooted in the Qur’ān and ḥadīths, such as the stinging of Nimrod's arrow is also encountered in the stories. Based on the narrations in the stories, it seems possible to draw the conclusion that the Oghuz Turks mentioned in the Book of Dede Korkut adopted Ahl al-Sunnah (people of Sunnah) interpretation of Islam. However, it should be reminded that this implication will lose its meaning if it is proved that the original versions of the stories were redesigned according to the interpretation of Ahl al-Sunnah in the process of transferring them into writing.

The type of ‘Al-isnād al-āli’ (higher chain of authority) which has great importance for the science of ḥadīths that constitutes the second best source of the Islam, expresses the value in terms of its proximity to the period of the Prophet Muhammad (peace be upon him). If ḥadīth has ‘al-isnād al-āli’ in the works of the scholars provides us with assurance on the intend of the ḥadīth. For this reason, the values of the works of those authors who have constructed (...) their works with al-isnād al-āli undoubted in the science of ḥadīth. However the work of Abu al-Jahm al-Bāhilī’s (d. 228/842) named al-Juz‘ had that kind of ḥadīth, it has not appreciated by scholars, he could not get enough attention in his period and after it. His work contains famous scholar al-Layth Ibn Sa‘d’s (d. 175/791) narrative who claimed by ḥadīth scholars that his students neglected and omitted his ḥadīths and knowledge. Al-Layth Ibn Sa‘d was known doing transmission by written copies. The similarity of al-Layth Ibn Sa‘d narrations in al-Juz‘ with al-Layth narrations, which are also found in other sources, strengthens the claims of the existence of a narrative process based on the written texts in the early periods. In this study, these transfers of Abu al-Jahm reflected on other works will be examined and tried to build narrations of his teacher al-Layth Ibn Sa‘d. country, we can say that the article will contribute to the studies of the history of religions.Summary: Ḥadīth works written in the third century of hijri are the most distinguished sources. The most fundamental works in the science of ḥadīth were written in this time. In the following period, numerous studies have been committed to paper on them. One of the eminent works is the named al-Juz’, which belongs to Abu al-Jahm al-Bāhilī (d. 228/842). The author was not a person that was taken into consideration much during his time. It is possible to that he has been criticized about his scientific proficiency (al-Jarh). Nevertheless, al-Juz’ attracts attention due to the fact that it contains the type of ‘al-Isnād al-āli’ (higher chain of authority). Al-Isnād al-āli, which means access with the least number of narration from the author to the Prophet has very major role to determining of being dependable and certainty of the ḥadīths. The work of Abu al-Jahm which contains the ‘al-Isnād al-āli’ did not attract enough attention. However, another value of the al-Juz‘ is that its been included the narration of famous muhaddith Al-Layth Ibn Sa'd (d. 175/791). He is one of the valued mujtahid imams who have played an active and important role in second century of hijri. Al-Layth's narrations have been available insufficient amount present day. At this point the al-Juz‘ of Abu al-Jahm has great important because it contains many narrations of his shaykh Al-Layth Ibn Sa'd.The Juz‘ seems to has attracted the attention of the ḥadīths scholars in the following period. Indeed, various authors had the get authorization to narrate al-Juz‘. Furthermore, it is also known that some scholar in his period utilized his narration in their own study. For in¬stance, it was declared by Ibn Ḥajar (d. 852/1449) that al-Bukhārī (d. 256/870) had a narra¬tion belonging to Abu al-Jahm in his work ‘al-Ṣaḥīḥ al-Bukhārī’ with a muʻallaq chain (Omit¬ting his name). In the following periods, we come across famous muhaddith such as Aḥmad b. Ḥanbal (d. 241/855), al-Ṭabaranī (d. 360/971), Abū Bakr al-Marwazī (d. 292/905), al-Dāraquṭnī (d.385/995) and al-Bayhaqī (d. 458/1066) who received qualify of Juz's narra¬tion. Although the narrations of Abu al-Jahm are included in the prominent works of schol¬ars, it is clearly seems that the Juz‘ had not enough value except being procure as a written text. As far as we determined there are eleven narration of Abu al-Jahm in the main ḥadīth sources. In addition, we detected that some studies which contain some ḥadīth of al-Juz’ are list them in the same layout and order. This situation indicates that al-Juz’ is owned by these people as a duplicated edition and they narrated by not only orally transmitted but also spread by writing copy. This inference strengthens the theory which conceived by Modern researcher Fuad Sezgin (1924-2018) that ḥadīth transmission had conducted not only through oral transfer but also through written copies.Even though he lived in a very active time of oral transmission of ḥadīth and the time of specific journey for learning and pursuing ḥadīth, it is seen that Abu al-Jahm formed his Juz‘ from the ḥadīths that he procured only from his six shaykhs. That was quite less amount in that period. Juz‘, has an ʿAlāʾ al-Rijāl classification (ranked according to narrators) as ex¬pected in his period method. Abu al-Jahm began his study with his shaykh Al-Layth Ibn Sa'd’s narration, then completed with Sufyān ibn ʿUyayna’s. Juz‘ includes 112 ḥadīths. Ex¬cept two muʻallaq isnāds (omitting one or more narrators), all of ḥadīth has muttaṣil isnāds (narrators in the chain connected each other without omitting). Al-Juz‘ available nowadays in a published form. It seems that some of ḥadīth datas included in the Juz‘ have content against Islamic juris-prudential judgements. For example, the Prophet’s sayings ‘One or two swallow of breast milk does not make haram’ and ‘Nobody can fast or pilgrimage for the benefit of someone else’; allowing to Subay‘a al-Aslamī to marry without waiting her ‘iddah (waiting period of a woman after the death of her husband or divorce); when she gave birth, ʿUthmān b. ʿAffān’s permission to al-Rubay‘a bint Mu‘avvidh not to wait her ‘iddah; when ʿAbd Allāh b. ʿUmar has nasal bleeding he leaves the prayer, goes to wash, then back and continue where he leave off, without taking ablution; and describing marriage with polytheist women as for¬bidden (ḥarām). Of course, all this information must be examined within the framework of Islamic jurisprudence. However, Abu al-Jahm stands alone (tafarrūd) in such issues, it can be seen as the reasons to be recognized as a censured person (majrūḥ).Al-Juz‘ included 66 isnāds of Al-Layth Ibn Sa'd’s narration. Therefore it leaves behind all the works that compile the narration of Ibn Sa'd. That is why, we hypothesize that Juz‘ is a form of Al-Layth’s study that has survived to the present days. As a matter of fact, the muhaddiths who included the narrations of Al-Layth in their works, especially Ibn ḳuṭlūbughā could not ignore the Juz‘ of Abu al-Jahm; on the contrary, they took it as reference. In this case, it should be said that Abu al-Jahm al-Bāhilī is a loyal follower of Al-Layth and the word at¬tributed to Imām Shāfi‘ī and characterizing Al-Layth’s followers with disloyalty is invalid.

Mirrors for princes, in general, give advices to the rulers about the subtleties of political art. Another aim of these books is to define and explain the administration of the state and the duties of rulers based on experience. In consequence of this they reflect the practical ethics of the period in which they were written. As such, they resemble practical handbooks written for rulers. Another point regarding the mirrors for princes works in which the political understanding of the era (...) can be observed is that they generally use sacred texts in order to prove the political legitimacy or invalidity of the power, as well as the rightfulness or the unlawfulness of the claims to the throne. Evidences from the Qurʾān and the ḥadīth literature was almost always used to support such advocated opinions. In fact, during the Middle Ages when religion and politics were considered coupled, it was unthinkable that religious elements should not be included in the works of state administration. The important point here is that the verses and ḥadīths were sometimes removed from their contexts and interpreted and explained in a way to support the ideology of the author or the ruler whom the author presented his work. In this study, we will try to reveal the subjects in which the verses and ḥadīths used in the mirrors for princes, which is a genre that has emerged within the Islamic culture and civilization. Thus, we aim to prepare a background for the future studies, which will focus on a specific verse or ḥadīth.Summary: The first political splits in Islamic history occurred immediately after the death of prophet Muḥammad. These differences were resolved by the agreement of the majority of Muslims on Abu Bakr's name. Until the second half of the rule of the third caliph ʿUthmān, Muslims came together around the unifying power of the idea of conquest. Nevertheless, substantially as a result of economically based problems the period of tranquility in Islamic society came to an end and was replaced by disputes. Disputes turned into conflict and ultimately seperation fused with the massacre of ʿUthmān in the capital Medina turned into a big fire with the Battles of the Camel and Ṣiffīn, the emergence of Khārijīs, the formation of the Shia and the deepening of the intellectual divisions after the all of these. Islamic history has witnessed a clash of different religious views and beliefs. along with deepening of intellectual disagreements as a result of political debatesIn the Islamic political thought, especially the first two centuries process was formed around the views of the jurists, muḥaddiths and theologians. The first sources used by those who tried to justify their opinion in the differences of opinion experienced during this period were the Qurʾān and ḥadīth literature which Muslims accepted as the determining factor in all their acts. The views based on the Qur'an and the hadiths, which are the two main sources of Islamic religion, had been used to influence the people, legitimize the actions and refute the claims of the opponents. On the other hand the sort who gave direction to political thought changed and political thought adhered a new path with Turks and Persians served as bureaucrats and soldiers and took an active position in the state. Especially Persians carried the culture of advice to Islamic thought, which is the product of both Greek and Hind civilization. Such books had brought in the İslamic society with translation movements began in the Umayyad period and peaked with the Bayt al-Ḥikma in the Abbasid period. Together with these books, the ideas of these civilizations on ideal state administration, politics and morality were recognized by Muslim scholars.These type of works, which are famous in terms of Islamic thought as mirrors for princes, have been written by Muslim scholars since the middle of the eighth century. Mirrors for princes are political, moral and religious content books that gives the rulers practical advice to maintain their power in accordance with the religious orders and prohibitions, and to the consent of Allāh’s who grant them this authority and people which appointed for their administration. Mirrors for princes are mostly theoretical books since they are mostly focused on what should be. In addition, since they are written for names that currently hold power, they are centered on how the rulers can maintain and increase their power and with which practices the state will maintain its existence for a longer period. The basic point of political thought and political interpretation are concepts and definitions. When the concept meaning of a word is mentioned, it is generally considered that there is a general definition. However, the concepts reflect the meaning that the user assigns to him in the context of his thoughts, perceptions, criticisms, explanations and analyzes. Concepts such as fair, honest, brave, hero, beautiful, rich, good and clean express what the person imposes on the meaning. In other words, everyone’s experience determines the content of the concept so far. The meaning of the concepts varies with the age and its user of that concept. Even concepts such as justice, merit and consultation can change meaning in different periods and geographies. The concepts, which are often used to facilitate understanding, are sometimes used to judge, to mold or mislead the interlocutor. In this context, it is imperative to enter the mind of the user in order to make concept analysis.In Islamic civilization, the principles of management are explained with concepts. The idiosyncrasies that Muslims expect from an ideal ruler are defined as justice, consultation, merit, trust and legitimacy and a broad corpus has been written about the concepts related to the administration, especially those mentioned. One type of this corpus is mirrors for princes.In Islamic history, there are many Mirrors for princes who are written in different time periods by names coming from different geographies and different backgrounds. Although the advice given in Mirrors for princes indicate a great similarity to each other, the preferred arguments and examples in the foundation of the counsel are different. While the persons in active politics mostly based their opinions on political arguments, scholars with scientific tradition supported their advices with religious arguments.Verses are the leading religious elements highlighted in Mirrors for princes. While explaining the concepts and emphasizing the importance of the advices, many verses have been exploited. Some verses are used only by one author, while some verses are the subject of their work by many authors. In the same way, ḥadīths and the sentences accepted as ḥadīths were also used to reinforce the emphasis and meaning. At this point, sometimes the context of the verses and ḥadīths were not taken care of. In this study, we aim to address the use of religious elements.In the literature, different opinions have emerged about who is ülü’l-emr and the limits of obedience to ülü’l-emr that used describe the names of senior executives and leaders of society. The reason for the difference is that each sect or religious school provides an interpretation on the basis of grounding its own views in explaining the verse. Justice is the most emphasized concept among the advices given to the rulers in mirrors for princes. Justice, which is shown as the most important feature of a sovereign, has been regarded as extremely important for the state to existences until the Doomsday. In addition, justice has been described as the most important condition for the maintenance of the state/sovereign authority. Consultation was important to make the right decision.Verses and ḥadīths were used in the explanations about the personal characteristics of the sovereign. Some features such as being compassionate, keeping promise, controlling anger, patience, honesty, blessing, extravagance, self-esteem, break a promise, revoke a promise and arrogance have become the subject of politics. When the mirrors for princes are considered as a whole, it is seen that religion and state are considered as inseparable twin brothers, taken one step further the understanding that accepts religion and the world as brothers especially is a product of the old Persian tradition. In this understanding, religion was accepted as the root and was given the duty of its patronage to political authority. It is seen that in the Mirrors for princes verses and ḥadīths hold a significant amount. As the reason for this can be said that along with religion takes place on the basis of morality, the authors of the Mirrors for princes, which put deep meanings on the relationship between religion and the state in the period that we are dealing with, consider both institutions to be complementary and integrative.

Digital technologies have become a major factor for innovation in the business environment. Organisations have taken advantage of digitised data and information to increase performance. However, there is still little research focusing on the effect of digitalisation on organisational culture, which in the end will affect performance. We develop this research by exploring a proposed model involving digital organisational culture with the final goal to enhance organisational performance. The research involved 263 managers of state-owned companies in Indonesia. We analysed the (...) theoretical model by using structural equation modelling and processed the data using the SmartPLS version 3 software. We conclude that digital organisational culture can become an essential factor in improving digital strategy and performance. However, business digitalisation does not really affect digital organisational values. (shrink)

We show in this paper that the AGM postulates are too weak to ensure the rational preservation of conditional beliefs during belief revision, thus permitting improper responses to sequences of observations. We remedy this weakness by proposing four additional postulates, which are sound relative to a qualitative version of probabilistic conditioning. Contrary to the AGM framework, the proposed postulates characterize belief revision as a process which may depend on elements of an epistemic state that are not necessarily captured by a (...) belief set. We also show that a simple modification to the AGM framework can allow belief revision to be a function of epistemic states. We establish a model-based representation theorem which characterizes the proposed postulates and constrains, in turn, the way in which entrenchment orderings may be transformed under iterated belief revision.

Given that health systems research involves different aims, approaches, and methodologies as compared to more traditional clinical trials, the ethical issues present in HSR may be unique or particularly nuanced. This article outlines eight pertinent ethical issues that are particularly salient in HSR and argues that the ethical review process should be better tailored to ensure more efficient and appropriate oversight of HSR with adequate human protections, especially in low- and middle-income countries. The eight ethical areas we discuss include the (...) nature of intervention, types of research subjects, units of intervention and observation, informed consent, controls and comparisons, risk assessment, inclusion of vulnerable groups, and benefits of research. HSR involving human participants is necessary to ensure health systems strengthening and quality of care and to guide public policy intelligently. Health systems researchers must carefully define their intent and goals and openly clarify the values that may influence the premises and design of protocols. As new types of population-level research activities become more commonplace, it is critical that institutional review board and research ethics committee review processes evolve to evaluate these research protocols in ways that address the nuanced features of these studies.

Recent work has shown that the input-output behavior of some common machine learning classifiers can be captured in symbolic form, allowing one to reason about the behavior of these classifiers using symbolic techniques. This includes explaining decisions, measuring robustness, and proving formal properties of machine learning classifiers by reasoning about the corresponding symbolic classifiers. In this work, we present a theory for unveiling the _reasons_ behind the decisions made by Boolean classifiers and study some of its theoretical and practical implications. (...) At the core of our theory is the notion of a _complete reason,_ which can be viewed as a necessary and sufficient condition for why a decision was made. We show how the complete reason can be used for computing notions such as sufficient reasons (also known as PI-explanations and abductive explanations), how it can be used for determining decision and classifier bias and how it can be used for evaluating counterfactual statements such as “a decision will stick even if...because....” We present a linear-time algorithm for computing the complete reasoning behind a decision, assuming the classifier is represented by a Boolean circuit of appropriate form. We then show how the computed complete reason can be used to answer many queries about a decision in linear or polynomial time. We finally conclude with a case study that illustrates the various notions and techniques we introduced. (shrink)

203 surveys were considered complete and were included in the analysis. Written consent was not used by nearly 40% of the researchers.

This article draws attention to the limited amount of scholarship on what constitutes fairness and equity in resource allocation to health research by individual funders. It identifies three key decisions of ethical significance about resource allocation that research funders make regularly and calls for prioritizing scholarship on those topics – namely, how health resources should be fairly apportioned amongst public health and health care delivery versus health research, how health research resources should be fairly allocated between health problems experienced domestically (...) versus other health problems typically experienced by disadvantaged populations outside the funder's country, and how domestic and non-domestic health research funding should be further apportioned to different areas, e.g. types of research and recipients. These three topics should be priorities for bioethics research because their outcomes have a substantial bearing on the achievement of health justice. The proposed agenda aims to move discussion on the ethics of health research funding beyond its current focus on the mismatch between worldwide basic and clinical research investment and the global burden of disease. Individual funders’ decision-making on whether and to what extent to allocate resources to non-domestic health research, health systems research, research on the social determinants of health, capacity development, and recipients in certain countries should also be the focus of ethical scrutiny.

We address in this paper the problem of counting the models of a propositional theory under incremental changes to its literals. Specifcally, we show that if a propositional theory Δ is in a special form that we call smooth, deterministic, decomposable negation normal form, then for any consistent set of literals S, we can simultaneously count the models of Δ ∪ S and the models of every theory Δ ∪ T where T results from adding, removing or flipping a literal (...) in S. We present two results relating to the time and space complexity of compiling propositional theories into sd-DNNF. First, we show that if a conjunctive normal form has a bounded treewidth, then it can be compiled into an sd-DNNF in time and space which are linear in its size. Second, we show that sd-DNNF is a strictly more space efficient representation than Free Binary Decision Diagrams. Finally, we discuss some applications of the counting results to truth maintenance systems, belief revision, and model-based diagnosis. (shrink)

Refusing consent to organ donation remains unacceptably high, and improving consent rates from family or next-of-kin is an important step to procuring more organs for solid organ transplantation in countries where this approval is sought. We have thus far failed to translate fully our limited understanding of why families refuse permission into successful strategies targeting consent in the setting of deceased organ donation, primarily because our interventions fail to target underlying cognitive obstacles. Novel interventions to overcome these hurdles, incorporating an (...) understanding of cognitive psychology and behavioral change therapy, may be beneficial. One potential intervention is to use the concept of nudge theory, where decision-making is influenced by encouraging positive reinforcement and indirect suggestion. Purposefully nudging families to given consent for organ donation by understanding, and then overcoming, their inherent cognitive biases is novel but also controversial. This article explores the roles of relatives in decisions about organ donation, how nudge theory translates to organ donation and discusses the arguments for and against its application. (shrink)

This cross-sectional study was carried out to investigate the frequency of consanguineous marriage in a group of army conscripts in Ankara and the factors affecting this. Of 4153 soldiers, 387 were married. The rate of marriage between first cousins was found to be 19·1%, and the overall rate of consanguineous marriage was 24·1%. Consanguineous marriage was found to be significantly prevalent among soldiers who were born in and still living in the Eastern region; among those who lived in villages; among (...) those whose parents as well as themselves had low educational levels; and among those whose marriages were arranged by their families. Neither the payment of bride-price nor the presence of consanguinity between parents was a significant factor for consanguineous marriage. In addition, the age of the soldier and the age at marriage were significantly lower among soldiers married to first cousins than among soldiers whose marriages were not consanguineous. (shrink)

With developed country governments and high resource institutions engaging in research in low- and middle-income countries, we argue that these entities have a moral obligation to help build and strengthen research infrastructure and capacity so local scientists and institutions can adequately conduct studies to understand and resolve the health burdens in low and middle income countries. We explore the moral justifications and motivations behind engaging in research capacity strengthening in the health sector in LMIC at multiple levels. In highlighting these (...) issues, this paper aims to initiate a global discourse around why capacity development in LMIC has a moral basis at the individual, institutional and system levels.
