We have developed an example of hydrocarbon detection for an Ordovician cavern carbonate reservoir in western China with a burial depth exceeding 6600 m using amplitude variation with offset and spectral decomposition. We selected six production wells, three prolific oil wells, and three brine wells to test the hydrocarbon detection method. The three oil wells have been producing for more than three years, and the three water wells only produce brine. We performed spectral decomposition to the angle gathers and analyzed (...) amplitude variation patterns with incidence angles for different spectral components. Specifically, we compared the time corresponding to the peak spectral amplitude for different spectral components for the oil- and brine-saturated carbonate reservoirs. The main findings are as follows: Oil-saturated cavern carbonate reservoirs show decreasing peak time with increasing frequency; i.e., the high-frequency components travel faster than do the low-frequency components. The maximum time difference between the 10 and 50 Hz spectral components could reach 35 ms. In contrast, the brine-saturated carbonate reservoirs do not exhibit conspicuous variation in the peak time, AVO attributes extracted from the low-frequency spectral gathers are more robust than those extracted from the original seismic gathers, oil-saturated cavern carbonate reservoirs cause strong energies in the low-frequency spectral components and severe attenuation to the high-frequency spectral components at large incidence angles. In contrast, the brine-saturated carbonate reservoirs do not produce such phenomenon. Rock physics analysis for carbonate reservoirs under different saturation conditions was conducted. The synthetic gathers were generated for carbonate reservoirs under oil- and brine-saturated conditions. The spectrally decomposed synthetic gathers are in agreement with the real gathers. The results indicate that AVO analysis of spectrally decomposed prestack gathers could be used as an effective hydrocarbon detection method for carbonate reservoirs. (shrink)
This chapter narrates the author's fascination with the intriguing and elusive face and image of Hannah Arendt—as well as her life story. Experience and world events transformed her inner and outer appearance, etching her life story on her face. Her life story was that of an intellectual Jewish woman who experienced the European turmoil of the 20th century and tried to understand the sources of human evil and violence. The author traced her portrait from a very young woman to her (...) old age. The source materials included unfamiliar photos of Arendt at different stages of her life. (shrink)
The four volumes of this set bring together key contributions to the study of Shi’ism, giving access to material that has hitherto been scattered and difficult to locate. While the majority of the material stems from the past fifty years, earlier studies are included, providing insight into the field’s development. This collection reflects the increasingly interdisciplinary nature of today’s Shi’ite studies. Volume One covers the birth of Shi’ism and traces its development. The emphasis is on the socio-political history of communities (...) self-identifying as Shi’ite, focusing largely on the majority ‘Twelvers’, but also covering ‘offshoot’ sects. Volume Two consists of articles which explore the theologies and philosophical ideals of Shi’ism. Particular emphasis is given to those aspects of Shi’ite orthodoxy and orthopraxy which distinguish them from the Sunni majority. Volume Three is devoted to Shi’ite law, with special reference to the evolution of ‘independent reasoning’ – the principle which underpins the inherent dynamism of Shi’ite jurisprudence and which has ensured continuation of development down to the present day. Volume Four concentrates on the development of theories of government among the Shi’ite scholarly milieu, tracing political Shi’ism from its turbulent beginnings to its pre-modern and contemporary manifestation.

The legal-ethical dynamism in Islamic law which allows it to respond to the challenges of modernity is said to reside in the institution of ijtihād (independent legal thinking and hermeneutics). However, jurists like Mohsen Kadivar and Ayatollah Faḍlalla have argued that the “traditional ijtihād” paradigm has reached its limits of flexibility as it allows for only minor adaptations and lacks a rigorous methodology because of its reliance on vague and highly subjective juridical devices such as public welfare (maṣlaḥa), imperative necessity (...) (ḍarūra), emergency (iḍtirār), need (ḥāja), averting difficulty (‘usr) and distress (ḥaraj), hardship (mashaqqa), and harm (ḍarar) without interrogating the fundamentals (uṣūl) of ijtihād. In contrast, in the “foundational ijtihād” model theology, ethics, intellect, epistemology, linguistics, hermeneutics, modern sciences, history, cosmology, anthropology, and the sources of Islamic legal theory (uṣūl al-fiqh) interact with one another to obtain resolutions that are just and non-discriminatory.

Salt boundary interpretation is important for the understanding of salt tectonics and velocity model building for seismic migration. Conventional methods consist of computing salt attributes and extracting salt boundaries. We have formulated the problem as 3D image segmentation and evaluated an efficient approach based on deep convolutional neural networks with an encoder-decoder architecture. To train the model, we design a data generator that extracts randomly positioned subvolumes from large-scale 3D training data set followed by data augmentation, then feed a large (...) number of subvolumes into the network while using salt/nonsalt binary labels generated by thresholding the velocity model as ground truth labels. We test the model on validation data sets and compare the blind test predictions with the ground truth. Our results indicate that our method is capable of automatically capturing subtle salt features from the 3D seismic image with less or no need for manual input. We further test the model on a field example to indicate the generalization of this deep CNN method across different data sets. (shrink)
Counterfactual verbal irony, an evaluative form of figurative language wherein a speaker’s intended meaning is opposite to the literal meaning of his or her words, is used to serve many social goals. Despite recent calls for theoretical accounts to include the factors that influence irony interpretation, few studies have examined the individual differences that may impact verbal irony interpretation. The present study examined whether adults with elevated shyness would generate more negative interpretations of ironic statements. University students with varying degrees (...) of shyness listened to stories wherein one character made literal or ironic criticisms or compliments to another character. Participants then appraised each speaker’s belief and attitude. Self-reported shyness did not predict comprehension of the counterfactual nature of ironic statements. However, shyer adults rated speakers who made ironic compliments as being meaner than did adults low in shyness. Thus, while understanding that ironic speakers intended to communicate their true beliefs, shyer individuals construed the social meaning of irony more negatively. Such interpretive biases may lead shy individuals to more frequently take offense at ironic compliments and experience more negativity in social interactions. (shrink)
This study empirically investigated the impact of ethical leadership on employee burnout, deviant behavior and task performance through two psychological mechanisms: developing higher levels of employee trust in leaders and demonstrating lower levels of surface acting toward their leaders. Our theoretical model was tested using data collected from employees of a pharmaceutical retail chain company. Analyses of multisource time-lagged data from 45 team leaders and 247 employees showed that employees’ trust in leaders and surface acting significantly mediated the relationships between (...) ethical leadership and employee burnout, deviant behavior and task performance. We discuss the theoretical and practical implications of our findings for understanding how ethical leaders influence employees’ attitudes and behavior. (shrink)
Research indicates that religious values and ethical behavior are closely associated, yet, at a firm level, the processes by which this association occurs are poorly understood. Family firms are known to exhibit values-based behavior, which in turn can lead to specific firm-level outcomes. It is also known that one’s family is an important incubator, enabler, and perpetuator of religious values across successive generations. Our study examines the experiences of a single, multigenerational business family that successfully enacted their religious values in (...) their business. Drawing upon intergenerational solidarity and values-based leadership theory, and by way of an interpretive, qualitative analysis, we find that the family’s religious values enhanced their cohesion and were manifested in their leadership style, which, in turn, led to outcomes for the business. Our findings highlight the processes that underlie the relationship between religious values and organizational outcomes in family firms and offer insights into the role of solidarity in values-based leadership.

This paper introduces the Generalized Argumentation Theory which takes argumentation as a locally rational socio-cultural interaction governed by social norms and carried out through discourse between the members of a socio-cultural community in order to reason things out. Then we bring in the basic structure of generalized argumentation and the localized procedure of Generalized Argumentation Theory for studying the argumentative rules. On the basis of above introduction, we use the localized procedure to analyze a case of political argumentation by reciting (...) poems in ancient China. By doing so, it’s indicated that political argumentation by reciting poems, in essence, takes cultural principle of Li of the Spring and Autumn Period as argumentative rules and uses poems to express ideas, in virtue of which arguments are accepted as locally rational by the politicians at that time. At last, the Little Red Book quotation fight, a similar political activity, is discussed briefly to show the significance that ancient Chinese political argumentation has on contemporary argumentation.

In discussing the intricate and somewhat complex relationship between Shiʻism and Sufism, both in principle and essence or in their metahistorical reality as well as in time and history, we need hardly concern ourselves with the too often repeated criticism made by certain orientalists who would doubt the Islamic and Quranic character of both Shiʻism and Sufism. Basing themselves on an a priori assumption that Islam is not a revelation and, even if a religion, is only a simple ‘religion of (...) the sword’ for a simple desert people, such would-be critics brush aside as un-Islamic all that speaks of gnosis and esotericism, pointing to the lack of historical texts in the early period as proof of their thesis, as if the non-existent in itself could disprove the existence of something which may have existed without leaving a written trace for us to dissect and analyse today. The reality of Shiʻism and Sufism as integral aspects of the Islamic revelation is too blinding to be neglected or brushed aside by any would-be historical argument. The fruit is there to prove that the tree has its roots in a soil that nourishes it. And the spiritual fruit can only be borne by a tree whose roots are sunk in a revealed truth. To deny this most evident of truths would be as if we were to doubt the Christian sanctity of a St Francis of Assisi because the historical records of the first years of the Apostolic succession are not clear. What the presence of St Francis proves is in reality the opposite fact, namely, that the Apostolic succession must be real even if no historical records are at hand. The same holds true mutatis mutandis for Shiʻism and Sufism. In this paper in any case we will begin by taking for granted the Islamic character of Shiʻism and Sufism and upon this basis delve into their relationship. In fact Shiʻism and Sufism are both, in different ways and on different levels, intrinsic aspects of Islamic orthodoxy, this term being taken not only in its theological sense but in its universal sense as tradition and universal truth contained within a revealed form.

Hrushovski originated the study of “flat” stable structures in constructing a new strongly minimal set and a stable 0-categorical pseudoplane. We exhibit a set of axioms which for collections of finite structure with dimension function δ give rise to stable generic models. In addition to the Hrushovski examples, this formalization includes Baldwin's almost strongly minimal non-Desarguesian projective plane and several others. We develop the new case where finite sets may have infinite closures with respect to the dimension function δ. In (...) particular, the generic structure need not be ω-saturated and so the argument for stability is significantly more complicated. We further show that these structures are “flat” and do not interpret a group. (shrink)
This study empirically examined the propositions that ethical leadership is related to employees’ organizational citizenship behavior through two psychological mechanisms: a social learning mechanism, where employees emulate their supervisor’s behavior such as caring about their organization; and a social exchange mechanism that links ethical leadership to perceived procedural justice and employee’s organizational concern. Our theoretical model was tested using data collected from employees in a pharmaceutical retail chain company. Analyses of multisource time-lagged data from 93 team supervisors and 486 employees (...) showed that supervisors’ and employees’ organizational concern sequentially mediated the relationship between ethical leadership and employee OCB. It was also found that the link between ethical leadership and employee OCB was sequentially mediated by perceived procedural justice and employee’s organizational concern. Theoretical and practical implications of these findings are discussed. (shrink)
Against the backdrop of a global pandemic, this study investigates how U.S. higher education leaders have centered their crisis management on values and guiding ethical principles. We conducted 55 in-depth interviews with leaders from 30 U.S. higher education institutions, with most leaders participating in two interviews. We found that crisis plans created prior to the COVID-19 pandemic were inadequate due to the long duration and highly uncertain nature of the crisis. Instead, higher education leaders applied guiding principles on the fly (...) to support their decision-making. If colleges and universities infuse shared values into their future crisis plans, they will not have to develop a moral compass on the fly for the next pandemic. This paper suggests the following somewhat universal shared values: engage in accuracy, transparency, and accountability; foster deliberative dialog; prioritize safety; support justice, fairness, and equity; and engage in an ethic of care. To navigate ethics tensions, leaders need to possess crisis-relevant expertise or ensure that such expertise is present among crisis management team members. Standing up formal ethics committees composed of diverse stakeholders also is instrumental in navigating tensions inherent in crises. The next pandemic is already on the horizon according to experts. Through infusing values into future crisis plans, higher education leaders can be confident that their responses will be grounded in their communities’ shared values. (shrink)
