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)

We investigate whether religion acts as a deterrent to the types of mortgage misrepresentation that played a significant role in the recent housing boom and bust. Using a large sample of mortgages originated from 2000 to 2007, we provide evidence that local religious adherence is associated with a lower likelihood of home appraisal overstatement and owner occupancy misreporting. The evidence on borrower income misrepresentation is mixed. Religiosity does not appear to reduce the incidence of income misrepresentation; however, it seems to (...) restrain the degree to which income is misrepresented. Our results are generally consistent with the hypothesis that religion, as a set of social norms, fosters ethical behavior, and possibly risk aversion, in the mortgage market. (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)

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.

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 aim of this article is to examine the usefulness of spirituality and aesthetics for generating new perspectives and understandings with regard to business ethics. Using an interpretive mixed-methods approach, data were collected through an online survey of 223 respondents and focus group interviews with 20 participants. Analysis of the quantitative and qualitative data suggests that the presence of aesthetic spirituality and religious spirituality, along with the factors of optimism, contentment, making a difference and interconnectedness, are significantly associated with ethical (...) practice in the workplace. These factors may be focused upon when considering the ethical climate of organizations. Although this research does not support universal conclusions, the relationship between ethics, spirituality and aesthetics identified in the Australian services sector might be replicated elsewhere.

BACKGROUND: In today’s world of increased awareness regarding the concepts of corporate social responsibility (CSR) and corporate governance (CG), many firms in the developed countries consider noncompliance with CSR and CG standards as an important source of risk to their reputations with stakeholders. OBJECTIVE: The aim of this study is to investigate the relationship between the corporate social responsibility disclosure (CSRD) index and corporate factors, namely, board size, board independence, board meetings, CEO duality, a firm’s size, leverage, profitability and age. (...) This is the first known study in the case of Saudi Arabia to use the GRI 4th edition indicators to construct the CSRD index and evaluate Saudi listed firms. Results: The results show that profitability and size factor have positive and significant association with CSR disclosure in listed Saudi firms. While CG characteristics have no impact on CSR disclosure except board independence which has a negative impact. Conclusion: The average of CSRD index among Saudi firms is too low, it is about 11% that means Saudi firms disclose 11% of the information that they have to provide for stockholders according to GRI guidelines. Furthermore, the study concludes that the most polluted sectors “Ener. (shrink)

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.

This paper seeks to determine the extent of anti-corruption information disclosure in the sustainability reports originating from Gulf countries. Focus primarily on the fight against corruption, this study utilizes a deeply-rooted content analysis technique of corporate sustainability reporting, covering 66 Gulf Cooperation Council (GCC) firms during 2014. Strengthened by the application of institutional theory, insight into the results points to a state of limited maturity regarding the disclosure of anti-corruption procedures in the region. More specifically, the results highlight the compliance (...) in the reporting of conduct code, while reporting information on whistle-blowing was significantly less in comparison. Firms in Qatar and UAE ultimately release better informed reports; inclusive of detailed information on internal anti-corruption practices. (shrink)

BackgroundDescriptive studies examining publication rates and citation counts demonstrate a geographic skew toward high-income countries (HIC), and research from low- or middle-income countries (LMICs) is generally underrepresented. This has been suggested to be due in part to reviewers’ and editors’ preference toward HIC sources; however, in the absence of controlled studies, it is impossible to assert whether there is bias or whether variations in the quality or relevance of the articles being reviewed explains the geographic divide. This study synthesizes the (...) evidence from randomized and controlled studies that explore geographic bias in the peer review process.MethodsA systematic review was conducted to identify research studies that explicitly explore the role of geographic bias in the assessment of the quality of research articles. Only randomized and controlled studies were included in the review. Five databases were searched to locate relevant articles. A narrative synthesis of included articles was performed to identify common findings.ResultsThe systematic literature search yielded 3501 titles from which 12 full texts were reviewed, and a further eight were identified through searching reference lists of the full texts. Of these articles, only three were randomized and controlled studies that examined variants of geographic bias. One study found that abstracts attributed to HIC sources elicited a higher review score regarding relevance of the research and likelihood to recommend the research to a colleague, than did abstracts attributed to LIC sources. Another study found that the predicted odds of acceptance for a submission to a computer science conference were statistically significantly higher for submissions from a “Top University.” Two of the studies showed the presence of geographic bias between articles from “high” or “low” prestige institutions.ConclusionsTwo of the three included studies identified that geographic bias in some form was impacting on peer review; however, further robust, experimental evidence is needed to adequately inform practice surrounding this topic. Reviewers and researchers should nonetheless be aware of whether author and institutional characteristics are interfering in their judgement of research. (shrink)

This study is a socio-pragmatic analysis of persuasive strategies used by the participants in “al-ittijāh al-muʿākis”, “The Opposite Direction”, on the Al-­Jazeera TV channel. An ethnographic approach was adopted in the research; the analysis focused on the use of politeness strategies and face-saving and face-­threatening interactions in order to find out their persuasive factors. I observe that religious citations, prophetic sayings, proverbs, and metaphor are used predominantly by the participants in communicating various political issues. I argue that the persuasiveness of (...) these rhetorical strategies stems from their aesthetic influence in establishing moral credibility and in evoking emotional responses. I also argue that these rhetorical strategies are speech acts that indirectly provoke responses and/or aim at saving the speakers’ and/or addressees’ face. The study concludes that persuasiveness is facilitated in part by transferring socio-pragmatic meanings through the use of some politeness and figurative devices such as honorific modes, metaphors and proverbs.

Purpose This paper aims to provide a framework that might be used to tackle the multifaceted challenges facing humanity, which are increasing in seriousness and complexity. The Millennium Project had identified such challenges, and over time periods until and including 2050, which pose the question, how would societies cope with these challenges averting any disastrous results? contemplating the suggested ethical principles, and the three central beliefs of “end-based”, “rule-based” and “care-based”. In some cases, individuals might not be blamed to think (...) that “it is only a miracle” that might save humanity. Design/methodology/approach This paper, through the use of literature review, intends to provide an insight into these challenges, the suggested ethical principles and the three central beliefs, providing brief overview of the concept “miracle” leading to discussion on ethical mindsets, its components and their dimensions. Findings Concluding with framework for the way forward tackling these challenges. Research limitations/implications The limitation of this paper might lie in the fact that it is only a conceptual paper, but it calls on researchers to conduct further research using the suggested framework. Originality/value This might seem to be forward thinking, but it is a call for researchers to conduct more research in this area, and for governments to fund such research, to allow for the establishment of a method to refine the mindsets of individuals around the world to change into “ethical”, and thus, the world becomes better equipped to face and reduce the challenges and threats that are being faced by the world.

The aim of this article is to investigate the relatively neglected and under-theorized area of ethical mindsets in the Australian services sector. Employing a mixed-methods approach, quantitative data was collected through online survey of 66 items and qualitative data was collected by focus group interviews with 20 participants. An analysis of the survey data suggests that ethical mindsets exist, and the qualitative analysis allowed the identified components to be refined. This research potentially adds to developing business ethics literature about ethical (...) mindsets and contributes to the methodological debate about the efficacy of online surveys and the mixed-methods approach.

This book explores feminine archetypes and mythological figures in African and European traditions with an underlying goal of describing the foundations of social status for women. The author provides a rich corpus of mythology and tales to illustrate aspects of female and mother-daughter relationships. Diop analyzes the symbolic aspects of maternity and femininity, describing the social meaning of the matrix, breasts, and breastfeeding. A retrospective of female characters in African literature brings an interesting approach to explore the figures of (...) femininity and maternity in society. After an extensive analysis of African mythology and tales, the author proposes a way to integrate them in the clinical psychotherapy as a projective material. The analysis of clinical cases offers an example of how this material can be used in therapy with women from African descent. (shrink)

Twice in the 2020 term, in Bostock and Comcast, the Supreme Court doubled down on the reasoning of “but-for causation” to interpret antidiscrimination statutes. According to this reasoning, an outcome is discriminatory because of some status—say, sex or race—just in case the outcome would not have occurred “but-for” the plaintiff’s status. We think this reasoning embeds profound conceptual errors that render the decisions deeply confused. Furthermore, those conceptual errors tend to limit the reach of antidiscrimination law. In this essay, we (...) first unpack the ambiguity of this but-for causal reasoning. We then show that this reasoning arises from a misapplication of tort law principles within antidiscrimination law, and that, as a result, it is both conceptually and normatively indeterminate.

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)

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.
