RésuméLe problème de la détermination de la Qibla est l'une des questions cruciales qui se posent à la culture scientifique de l'Islam médiéval; le résoudre correctement nécessite tant des théories mathématiques que des observations. Les mathématiques relèvent de deux chapitres: la trigonométrie plane et la trigonométrie sphérique. L'observation et les instruments d'observation sont indispensables à la détermination des coordonnées géographiques de La Mecque et du lieu donné; ces coordonnées sont en effet les données que l'on entre dans les formules donnant (...) la Qibla. Dans son Almageste, Abū al-Wafāʾ résout brillamment ce problème. Son travail porte tant sur les mathématiques que sur l'observation; il obtient des solutions modernes, adéquates et faciles. En trigonométrie plane, il donne de nouvelles définitions des fonctions trigonométriques, démontre les formules des sinus, donne une approximation de sin 1° grâce à laquelle il construit des tables de sinus et de tangentes d'une grande précision. En trigonométrie sphérique, il démontre quatre nouveaux théorèmes dont la règle des tangentes ; cette règle lui permet de trouver, comme nous le montrerons, des solutions simples au problème de la détermination de la Qibla. En ce qui concerne les observations, il décrit trois instruments utilisés par lui plusieurs années de suite à Bagdad. Cet article, nourri de nombreux textes arabes originaux traduits et commentés, donne une description détaillée, technique et analytique, des méthodes mathématiques d'Abū al-Wafāʾ pour la détermination de la Qibla.

In the Greek/Indian period, it is noticeable that different radii were used in connection with the chord. This manner continued in the Indian period with the sine, i.e. different sine tables existed. But throughout the Arabic-Islamic period, there was stability in the radius (for the sine). At the time of al-Batt new terms were introduced, not as functions of angles but as lengths, and again different tables for the same term. Here these terms were not bounded to the circle, and (...) the term miqythe radiusfunctions al-Waf’s time, there was an advancement by introducing the new terms as functions of angles, and they were immediately bounded to the circle, and instead of having two circles in the same figure, a kind of unity appeared, and again there was stability in the value of r, and therefore only one table for each function, and thus the new functions started to appear more abstract than practical as the sine did before, and this unity remained fixed in the modern times.

In this paper, we are trying to summarize the peak of achievement of the Arabian logicians of the fifteenth century by making a classification and sketching in familiar terms the conditional and subjunctive syllogisms in Muḥammad Ibn Yusūf al-SSinūsī’s (1426-1490) work, i.e. in his explanation of Kitāb al-Muḫtaşar fī al-Manṭiq of al-Imām Muḥammad Ibn ʿArafa (1316- 1401).

The form of the conditional syllogism resembles that of the categorical syllogism, while its subject matter is at least a conditional premise, but its conclusion is always conditional conjunctive or disjunctive. This mixed structure to which we apply the rules of the categorical syllogism, is a structure of which Aristotle did not have an idea, and which the Stoics did not conceive, and which the non-Arabian logicians did not know until in modern times. But what we have to notice here (...) is the putting of a conditional matter in the form of the categorical syllogism, and it is this kind of hybridization, if we dare to say, which generated this mixed structure which appeared for the first time in the history of logic in the treatise on the logic of Ibn Sina and which can be considered a discovery by this author until proof to the contrary, and that the ancient Arabian logicians have taken the habit of exhibiting in their treatises.

According to foundationalism, some beliefs are justified but do not depend for their justification on any other beliefs. According to access internalism, a subject is justified in believing some proposition only if that subject is aware of or has access to some reason to think that the proposition is true or probable. In this paper I discusses a fundamental challenge to internalist foundationalism often referred to as the Sellarsian dilemma. I consider three attempts to respond to the dilemma – phenomenal (...) conservatism, BonJour’s classical foundationalism, and Fumerton’s classical foundationalism. I argue that, of these three, only the last seems to avoid getting impaled on one or the other horn of the dilemma. I end by responding to some concerns with Fumerton’s account. (shrink)

This chapter attempts to further the understanding of Sahelo‐Sudanic systems of slavery via enquiries into the daily life of slaves. This work is based on the memories of elders in certain villages within the zone of the ancient state of Kaarta and the buffer zone between it and the state of Segou, an area corresponding to the modern Malian administrative Cercles of Kolokani and Banamba. Temporally, the focus is on the period directly before the colonial era. In particular, the mode (...) of acquisition of slaves and the different types of local slavery are considered. (shrink)

El propósito de este artículo es mostrar que el escrito medieval no posee el mismo estatuto ni los mismos valores que hoy en día y, a partir de ahí, reaccionar ante la oposición entre lo oral y lo escrito que se utiliza a propósito de la literatura árabe en sus comienzos. La tesis propuesta defiende que, hasta la segunda mitad, si no hasta el final del siglo III de la Hégira, los textos de adab, aunque compuestos y producidos por escrito, (...) lo habían sido en la idea de que su circulación, su comunicación y recepción se haría, en la mayor parte de los casos, oralmente. Es este fenómeno el que define el estatus del adab de sus «autores», y de la naturaleza de las obras que lo constituyen. (shrink)

The examination of power, space, and identity formation within diasporic literature has garnered significant attention due to the escalating global mobility of migrants across the world. This article studies the complex integration of spatial hierarchy, civil violence, and gendered responses to power representations in Jhumpa Lahiri’s novel, The Lowland (2013). We utilise Henri Lefebvre’s theories to dissect the spatial dynamics of the novel across three dimensions: representations of space and conceived space, spatial practice and perceived space, and representational space and (...) lived space. Lefebvre’s framework is instrumental in understanding how physical and conceptual spaces can simultaneously serve as tools for domination and sites for transformative resistance. The novel weaves distinct spatial realms, such as the exclusive Tolly Club and the diminishing lowland, to symbolise postcolonialism and state control. The findings highlight how conceived space is portrayed as a postcolonial realm marked by violence and gendered spatial injustice, reflecting male dominance and societal norms that suppress female subjectivity. However, the study also reveals that this conformity is not static but showcases the agency of female characters like Gauri and Bijoli in resisting and renegotiating spatial constraints. (shrink)

The robustness of a system indicates its ability to withstand disturbances while maintaining its properties, performance, and efficiency. There are plenty of studies on the robustness of air transport networks in the literature. However, few works consider its mesoscopic organization. Building on the recently introduced component structure, we explore the impact of targeted attacks on the weighted world air transportation network on its components. Indeed, it contains five local components covering different regions and one global component linking these regions. We (...) investigate targeted attacks based on influential weighted centrality measures. Results show that the local components gradually separate from the world air transportation network as the fraction of removed airports grows. The weighted betweenness attack removes fewer top airports to isolate the regions compared to its alternatives. Furthermore, it is still convenient to travel locally in the separate areas. In contrast, strength and PageRank attacks need to target more airports to split the network. However, they are more disruptive. Indeed, the size of the isolated local components reduces drastically, so it becomes more challenging to travel locally. Looking at the world air transportation network through its component structure reveals a new viewpoint on its resilence. It opens new perspectives to design more efficient attacks. (shrink)

Si les sciences ont incontestablement imposé un modèle de rationalité universelle, il ne s'ensuit pas, comme l'Occident l'a trop facilement cru et fait croire, que la société occidentale elle-même et ses valeurs soient, elles aussi, universelles et puissent servir de normes uniques. La mondialisation actuelle et l'histoire ancienne des hommes manifestent la pluralité des modes socioculturels et des règles éthiques. La Rationalité, qui devrait résulter d'une réelle intersubjectivité, ne peut désormais advenir que par la participation de tous et par une (...) convergence des rationalités jusque-là plurielles. L'Afrique est donc nécessairement incluse dans ce débat pour lequel elle propose des paradigmes universalisables. (shrink)

This article draws on the ecological model of teacher agency and elaborates on how teacher agency is achieved, its components and how it could be strengthened. This model highlights professional competence, structural and cultural context, and professional purpose as the main elements of achieving agency. In this paper, we specify some elements of the ecological model and elaborate on how three types of reflection could be used to strengthen conditions for achieving teacher agency. These include, first, procedures aimed at articulating (...) the theory of action, including effective strategies, rules and principles for practice; second, procedures of practical reflection, aimed at fostering the conceptualization of practice and the understanding of oneself as a teacher; and third, procedures of critical reflection, which help to address the inequalities and malpractices of education and society. The main importance of this paper is to extend the practical relevance of the ecological model for teacher learning settings. (shrink)

Most models of corporate social responsibility revolve around the controversy as to whether business is a single dimensional entity of profit maximization or a multi-dimensional entity serving greater societal interests. Furthermore, the models are mostly descriptive in nature and are based on the experiences of western countries. There has been little attempt to develop a model that accounts for corporate social responsibility in diverse environments with differing socio-cultural and market settings. In this paper an attempt has been made to fill (...) this gap by developing a two-dimensional model of corporate social responsibility and empirically testing its validity in the context of two dissimilar cultures – Australia and Bangladesh. The two dimensions are the span of corporate responsibility and the range of outcomes of social commitments of businesses. The test results confirm the validity of the two-dimensional model in the two environments. The Factor analysis revealed two leading dimensions. Cluster analysis pointed to two distinctive clusters of managers in both Australia and Bangladesh, one consisting of managers with a broad contemporary concept of social responsibility, and the other with a limited narrow view. The paper concludes that corporate social responsibility is two-dimensional and universal in nature and that differing cultural and market settings in which managers operate may have little impact on the ethical perceptions of corporate managers.

This chapter centers around the question of whether theism is rational. We begin by discussing different theories of rationality, and introducing some importantly related epistemic concepts and controversies. We then consider the possible sources of rational belief in God and argue that even if these provide some positive support, the fact of religious disagreement defeats the rationality of theism.

We investigate the theory Peano Arithmetic with Indiscernibles ( \(\textrm{PAI}\) ). Models of \(\textrm{PAI}\) are of the form \(({\mathcal {M}},I)\), where \({\mathcal {M}}\) is a model of \(\textrm{PA}\), _I_ is an unbounded set of order indiscernibles over \({\mathcal {M}}\), and \(({\mathcal {M}},I)\) satisfies the extended induction scheme for formulae mentioning _I_. Our main results are Theorems A and B following. _Theorem A._ _Let_ \({\mathcal {M}}\) _be a nonstandard model of_ \(\textrm{PA}\) _ of any cardinality_. \(\mathcal {M }\) _has an expansion (...) to a model of _ \(\textrm{PAI}\) _iff_ \( {\mathcal {M}}\) _has an inductive partial satisfaction class._ Theorem A yields the following corollary, which provides a new characterization of countable recursively saturated models of \(\textrm{PA}\) : _Corollary._ _A countable model_ \({\mathcal {M}}\) of \(\textrm{PA}\) _is recursively saturated iff _ \({\mathcal {M}}\) _has an expansion to a model of _ \(\textrm{PAI}\). _Theorem B._ _There is a sentence _ \(\alpha \) _ in the language obtained by adding a unary predicate_ _I_(_x_) _to the language of arithmetic such that given any nonstandard model _ \({\mathcal {M}}\) _of_ \(\textrm{PA}\) _ of any cardinality_, \({\mathcal {M}}\) _has an expansion to a model of _ \(\text {PAI}+\alpha \) _iff_ \({\mathcal {M}}\) _has a inductive full satisfaction class._.

The relationship between ecology and democracy has a complex history and an uncertain future. Ecological crises threaten all forms of life on earth, and democracy too is endangered, as popular discontent, elite malfeasance, and unresponsive institutions herald crisis if not collapse. It is clear that our present political concepts and institutions are inadequate for meeting the challenges of living in right relation with the more-than-human world and, moreover, that these inadequacies are themselves symptoms of a failing political-cultural story and a (...) lack of concrete practices of ecological renewal, a story that does not recognize that there is no "people" without the earth and that power is not held by humans alone but in common with the natural world--intensifying weather events effected by climate change are only the most obvious example. Earthborn Democracy upends conventional accounts, which view democracy as a modern invention, by probing deep histories of egalitarian political organization beyond the ancient Athenian efforts so feared by the American founders in the premodern Americas, Mesopotamia, and many other egalitarian cultures. Unlike the constitutional democracies in nation-states, which are in service to economic directives, the political practices and stories excavated in the book illustrate the interdependence necessary to inspire and orient the work of ecological and democratic renewal. Responses to climate catastrophe call for an understanding of how unconscious desire can be a resource for collective democratic action. Developing an embodied account of the unconscious in which a desire for pleasure is central, the authors examine the knowledge and living traditions of Indigenous communities; the incorporation of "pleasure activism" into contemporary social movements and antiracist struggles; and practices of cooperation-cross-species affinity and relational grassroots political organizing around the world. The resonances across these examples trace the possibility for renewal of individual and collective selves through the work of ecological attunement and restoration. Building from re-envisioned democratic histories and this radical rereading of the collective unconscious, they show how contemporary political experiments and practices might cultivate and channel desires for autochthonous-earthborn-democracy, as the Athenian mythos names it.

Comment parler d'humanisme aujourd'hui? À partir d'une lecture anthropologique de Montaigne, ce livre aborde cette question par la notion de diversité au sein d'une humanité une : la capacité à concevoir et juger font de l'humanité une seule espèce. Lire Montaigne permet d'aller vers la reconnaissance de 'l'humanité des autres', celle de tous ceux qui ont résisté à l'esclavage, à la conversion forcée, au colonialisme, à l'inquisition. Sa voix lointaine nous fait entendre ceux qui crient justice en disant que 'la (...) vie des Noirs compte', ou ceux qui sont devenus une 'humanité mobile', exposés au sort funeste de la noyade ou de la mendicité, et qu'on appelle 'migrants'. En récusant les concepts de 'sauvage', de 'primitif', de 'barbare', c'est le bon sens de tous qui est dans ce livre honoré, un bon sens qui est à la base de tout acte de résistance, c'est-à-dire de tout acte de liberté."--Page 4 of cover.

Conceptions of teaching quality and teacher accountability, and the values and assumptions that underpin them, are relatively under‐examined by policy makers. We suggest ways in which philosophers might address this deficit, with reference to policy concerns found in the United Kingdom (UK). Further philosophical questions are generated by this process of reflection and we offer a partial analysis of those we judge to be of particular significance. While optimistic generally, we identify three challenges to asserting a role for philosophical analysis (...) in policy, practice and research concerned with teacher education, and urge philosophers of education to engage in constructive dialogue with other critical and reflective thinkers in the field of education.

Religion is a significant social force on organizational practice yet has been relatively underexamined in organization theory. In this article, I assert that the institutional logics perspective is especially conducive to examine the macrolevel role of religion for organizations. The notion of the religious logic offers conceptual means to explain the significance of religion, its interrelationship with other institutional orders, and embeddedness into and impact across interinstitutional systems. I argue for intrainstitutional logic plurality and show that specifically the intrareligious logic (...) plurality has been rather disregarded with a relative focus on Christianity and a geographical focus on “the West.” Next, I propose the concept of interinstitutional logic prevalence and show that the religious logic in particular may act as a metalogic due to its potential for uniqueness, ultimacy, and ubiquity. Through illustrations from Islamic Finance and Entrepreneurship, I exemplify implications of logic plurality and prevalence for organizations and societies. (shrink)

BackgroundPeople say it is hard to stay truly positive in Lebanon. Studies showed that 63% of Lebanese young adults are highly dissatisfied with their country. In fact, young adults are the most vulnerable population to stressors in Lebanon since their future is at stake and it is their time to shape their lives in a country that cripples them. This study aimed to assess factors associated with positivity among a sample of Lebanese university students despite the various stressors they are (...) facing on top of the economic collapse and the COVID-19 pandemic.MethodsThis cross-sectional study was conducted between November and December 2021. A total of 333 participants was recruited through convenience sampling and snowball technique through several areas in Lebanon’s governorates. A linear regression taking the positivity score as the dependent variable was adopted and all variables that showed a correlation > │0.24│ in absolute value were entered in the final model as independent.ResultsA linear regression taking the positivity score as the dependent variable showed that more positive experiences in life, more flourishing, living in rural area compared to urban, and female gender were significantly associated with more positivity.ConclusionThis study demonstrated that the youth’s positivity is strongly affected by age, gender, residency, and the country they live in that will both directly and indirectly shape their life experiences and their ability to flourish and prosper. Along with all the efforts done to help during this collapse and alleviate the stress that young adults are enduring, follow-up studies are still needed to determine accurate coping techniques that pushes these young adults to think positively in a country where negativity reigns and all else fails.

BackgroundProfessional ethics refers to the use of logical and consistent communication, knowledge, clinical skills, emotions and values in nursing practice. This study aimed to explore and describe factors that affect professional ethics in nursing practice in Iran.MethodsThis qualitative study was conducted using conventional content analysis approach. Thirty nurses with at least 5 years of experience participated in the study; they were selected using purposive sampling. Data were collected through semi-structured interviews and analyzed using thematic analysis.ResultsAfter encoding and classifying the data, (...) five major categories were identified: individual character and responsibility, communication challenges, organizational preconditions, support systems, educational and cultural development.ConclusionsAwareness of professional ethics and its contributing factors could help nurses and healthcare professionals provide better services for patients. At the same time, such understanding would be valuable for educational administrators for effective planning and management. (shrink)

Research about the role of religion in entrepreneurship and more broadly management is sparse. In this conceptual article, we complement existing entrepreneurship theory by examining entrepreneurship from an Islamic perspective. EIP is based on three interconnected pillars: the entrepreneurial, socio-economic/ethical, and religio-spiritual. We outline how Islam shapes entrepreneurship at the micro-, meso-, and macro-level, indicate how Islam may be considered an entrepreneurial religion in the sense that it enables and encourages entrepreneurial activity, review research streams interlinking Islam with entrepreneurship and (...) management and outline promising research approaches.

In “Compassionate Phenomenal Conservatism” (2007), “Phenomenal Conservatism and the Internalist Intuition” (2006), and Skepticism and the Veil of Perception (2001), Michael Huemer endorses the principle of phenomenal conservatism, according to which appearances or seemings constitute a fundamental source of (defeasible) justification for belief. He claims that those who deny phenomenal conservatism, including classical foundationalists, are in a self-defeating position, for their views cannot be both true and justified; that classical foundationalists have difficulty accommodating false introspective beliefs; and that phenomenal conservatism (...) is most faithful to the central internalist intuition. I argue that Huemer’s self-defeat argument fails, that classical foundationalism is able to accommodate fallible introspective beliefs, and that classical foundationalism captures a relatively clear internalist intuition. I also show that the motivation for phenomenal conservatism is less than clear. (shrink)

Bangladesh experienced a massive surge in humanitarian crises after the 1971 Liberation War due to the systematic use of violence at both public and private spheres. Fictional accounts of the post-conflict period depict women as subjected to institutionalised sexism and aggravated physical and mental violence. Critical studies on such narratives often reiterate a stereotypical and essentialising discourse surrounding women’s identity, characterising them as helpless and passive victims of discrimination and exploitation. Drawing upon Judith Butler’s notions of precarity and agency, we (...) argue that the Bangladeshi-born British writer Tahmima Anam’s The Good Muslim transcends victimhood narratives by creating a more nuanced image of woman as vulnerable victims and resisting subjects at the same time. The novel is preoccupied with notions of vulnerability, violence, religious zealotry, and family estrangement. The findings reveal that the precariousness of women in the post-war period is caused and aggravated by violence and oppression perpetrated at political, social, and religious spheres. Female characters like Maya and Piya are presented as empowered agents of transformation when it comes to vulnerable situations that render them as insignificant and precarious. The study concludes that the novel contests and alters the stereotypical representations of women embedded in normalising and hegemonic discourses. (shrink)

The clichés attached to Islam and Muslim women that the West had perpetuated since the Middle Ages and that were later propagated by Orientalist writers and painters, are reviewed in this article. The emergence of the subject of women as the centrepiece of western accounts of Islam in the late 19th century is equated with the beginning of European colonialism in Muslim countries, and the reasons for choosing the two controversial issues related to Muslim women: polygamy and the veil. It (...) clarifies the status of women before Islam and after its Revelation, assessing the positive and little-known aspects of the Muslim woman's role throughout history and the grounds for the deterioration of her status. The article closes with a matter-of-fact assessment of the position of women in the Islamic world today, reproving any approach based on generalities and oversimplifications when dealing with Islam-related issues.
