ABSTRACTThis essay focuses on the millennial generation of Sikhs in the United States. Based on extended ethnographic research in Sikh communities, the author explores the role of Sikh millennials in the making of an ‘American Sikhism’, the contours of which are taking shape having followed after the explosive growth of gurdwara communities – and the educational, social, and other resources they provide – which were largely made possible by the affluence of Sikh communities beginning with the previous ‘Brain Drain’ generation. In particular, the author discusses this ‘kirtan generation’ of Sikhs, educated in gurdwara schools, and their growing leadership of Sikh communities. 相似文献

The crisis of European sciences in Husserl’s late work diagnoses Galilean science as specifically and necessarily losing touch with the intuitive evidence that would legitimate it due to its reliance on a formal-mathematical conceptual apparatus. While the vast majority of Husserl’s late work was focussed on a critique of the formal-mathematical paradigm of the physical science of nature, at several points the possibility of biology as the exemplary science is raised to suggest that the lack of a reliance on formal-mathematical conceptual language would mean that a systemic crisis would not occur in such a case. This investigation considers the grounds for the expectation that biology would not engender a crisis, suggests that a paradigmatic role for ecology would more adequately address this expectation, and finally claims that the question of the relation between a specific exemplary science and transcendental phenomenology is not fully resolved even in this case. 相似文献

Testing autocorrelation and partial autocorrelation: Asymptotic methods versus resampling techniques
Zijun Ke Zhiyong Zhang 《The British journal of mathematical and statistical psychology》2018,71(1):96-116
Autocorrelation and partial autocorrelation, which provide a mathematical tool to understand repeating patterns in time series data, are often used to facilitate the identification of model orders of time series models (e.g., moving average and autoregressive models). Asymptotic methods for testing autocorrelation and partial autocorrelation such as the 1/T approximation method and the Bartlett's formula method may fail in finite samples and are vulnerable to non-normality. Resampling techniques such as the moving block bootstrap and the surrogate data method are competitive alternatives. In this study, we use a Monte Carlo simulation study and a real data example to compare asymptotic methods with the aforementioned resampling techniques. For each resampling technique, we consider both the percentile method and the bias-corrected and accelerated method for interval construction. Simulation results show that the surrogate data method with percentile intervals yields better performance than the other methods. An R package pautocorr is used to carry out tests evaluated in this study. 相似文献

Central Asia as the economic and geopolitical tension nexus: Some implications for the world futures
Askar Akaev 《World Futures: Journal of General Evolution》2018,74(1):36-46
During the last millennium the world economic and geopolitical conflicts were to a great extent connected: different crises in the World System's evolution stimulated geopolitical shifts and vice versa. This article argues that in the 15th century different geopolitical events and conflicts in Central Asia initiated the fall of the previous World System and the rise of the new one. This transformation resulted in the fall of overland and river trade routes, including the Great Silk Route, which passed through Central Asia. World trade shifted to sea and ocean routes, and European countries became the center of the new World System. Now, in the beginning of the 21st century a new transformation of the World System is underway. The center of economic and political development is migrating gradually to the East: this is why the geopolitical role of the Central Asian states is increasing. Central Asian states are a very important part of the New Silk Route; this route is to connect Eastern Asia with Europe and the Middle East. The United States, China, Russia, and other states are ardently competing to control the New Silk Route. Hence, different geopolitical, social, and military conflicts are probable in Central Asia. So economic and political integration in Eurasia between Russia, China, the United States and Central Asian states is very important for the geopolitical stabilization of the region. The article evaluates the main scenarios of geopolitical changes in Central Asia. 相似文献

CLIMATE CHANGE,LAUDATO SI', CREATION SPIRITUALITY,AND THE NOBILITY OF THE SCIENTIST'S VOCATION 下载免费PDF全文
Matthew Fox 《Zygon》2018,53(2):586-612
This exploration into spirituality and climate change employs the “four paths” of the creation spirituality tradition. The author recognizes those paths in the rich teachings of Pope Francis’s encyclical, Laudato Si' and applies them in considering the nobility of the scientist's vocation. Premodern thinkers often resisted any split between science and religion. The author then lays out the basic archetypes for recognizing the sacredness of creation, namely, the Cosmic Christ (Christianity); the Buddha Nature (Buddhism); the Image of God (Judaism); the “Primordial Man” (Hinduism), as well as the premodern universal teaching of “God as Beauty.” He addresses the subject of evil which deserves serious attention in the face of the realities posed by climate change and the resistance to addressing them. In the concluding section, the author speaks of a new Order of the Sacred Earth that was launched in fall 2017 to gather persons of whatever spiritual tradition or none to devote themselves to preserving Mother Earth. 相似文献

This article considers question‐begging's opposite fallacy. Instead of relying on my beliefs for my premises when I should be using my adversary's beliefs, I rely on my adversary's beliefs when I should rely on my own. Just as question‐begging emerges from egocentrism, its opposite emerges from other‐centrism. Stepping into the other person's shoes is an effective strategy for understanding him. But you must return to your own shoes when forming your beliefs. Evidence is agent centered. Other‐centric reasoning is most striking when both parties partake simultaneously. We are then treated to the spectacle of each side using the other's premises to establish its conclusion. These remarkable debates arise regularly when there is open disagreement about whether a right‐conferring relationship has ended. Those who contend the relationship is abrogated will be tempted to stand on the rights persistently credited to them by their adversary. 相似文献
