This essay, based on a “militant ethnography” of the attempts of the small radical grassroots activist group, Our London (a pseudonym), to mobilize a collective oppositional politics through activities around an election campaign, engages critically with E. Laclau and C. Mouffe's arguments on discourse and collectivity in Hegemony and Socialist Strategy (London: Verso, 1985). I argue, on the basis of my findings, that while their model does provide insights that help describe the process of building collectivity from among disparate perspectives and identities, we need to go beyond a focus on discourse alone and consider the ways politics is shaped by material contexts. This is necessary if we are to understand the continued appeal of class politics as well as the difficulties in mobilizing collectivity in highly unequal and fragmented cities. From an activist perspective, the essay also highlights how developing a conception of collective interests and a critique of overarching systems of exploitation can be important in building political unity.  相似文献

The U.S. electric power system is increasingly vulnerable to the adverse impacts of extreme climate events. Supply inadequacy risk can result from climate‐induced shifts in electricity demand and/or damaged physical assets due to hydro‐meteorological hazards and climate change. In this article, we focus on the risks associated with the unanticipated climate‐induced demand shifts and propose a data‐driven approach to identify risk factors that render the electricity sector vulnerable in the face of future climate variability and change. More specifically, we have leveraged advanced supervised learning theory to identify the key predictors of climate‐sensitive demand in the residential, commercial, and industrial sectors. Our analysis indicates that variations in mean dew point temperature is the common major risk factor across all the three sectors. We have also conducted a statistical sensitivity analysis to assess the variability in the projected demand as a function of the key climate risk factor. We then propose the use of scenario‐based heat maps as a tool to communicate the inadequacy risks to stakeholders and decisionmakers. While we use the state of Ohio as a case study, our proposed approach is equally applicable to all other states.  相似文献

In 1920 and 1922, an Indian Christian called Sadhu Sundar Singh toured Britain. Widely renowned in the global Christian community in the interwar period, Singh was notorious for certain stories of miracles, for his appearance and for the ways in which he epitomised Eastern Christianity. Using Singh’s correspondence and a range of newspapers, this article argues that British audiences were attracted to Singh because of his appearance and ethnicity and because he conformed to stereotypes of essentialised Indian spirituality despite his Christian faith. It argues that the reception to Singh in Britain must be understood in relation to the perpetuation of Orientalist understandings of Indians and Indian religions in the interwar period.  相似文献

A number of models have been proposed in the literature to model data reflecting bathtub-shaped hazard rate functions. Mixture distributions provide the obvious choice for modelling such data sets but these contain too many parameters and hamper the accuracy of the inferential procedures particularly when the data are meagre. Recently, a few distributions have been proposed which are simply generalizations of the two-parameter Weibull model and are capable of producing bathtub behaviour of the hazard rate function. The Weibull extension and the modified Weibull models are two such families. This study focuses on comparing these two distributions for data sets exhibiting bathtub shape of the hazard rate. Bayesian tools are preferred due to their wide range of applicability in various nested and non-nested model comparison problems. Real data illustrations are provided so that a particular model can be recommended based on various tools of model comparison discussed in the paper.  相似文献

In this paper, we propose a new nonparametric simultaneous test for dual alternatives. Simultaneous tests for dual alternatives are used for pattern detection of arsenic contamination level in ground water. We consider two possible patterns, namely, monotone shift and an umbrella-type location alternative, as the dual alternatives. Pattern recognition problems of this nature are addressed in Bandyopadhyay et al. [5], stretching the idea of multiple hypotheses tests as in Benjamini and Hochberg [6]. In the present context, we develop an alternative approach based on contrasts that helps us to detect three underlying pattern much more efficiently. We illustrate the new methodology through a motivating example related to highly sensitive issue of arsenic contamination in ground water. We provide some Monte-Carlo studies related to the proposed technique and give a comparative study between different detection procedures. We also obtain some related asymptotic results.  相似文献

Virtual volunteering refers to the use of the Internet for volunteer services. It is an emerging phenomenon among every age group; however, the current study examines if it is a viable option for older people. Older adults are the fastest growing Internet users. They are also more civic minded than younger generations, thus the purpose of this study is to explore this relatively new area research. Data for this study have been collected using qualitative tools such as semistructured, partly open-ended interviews with older virtual volunteers affiliated with SeniorNet, an organization that facilitates virtual volunteering exclusively for older people. The study ends with suggestions for future research directions. Implications of this study include reconceptualization of virtual volunteering as a strategic tool to recruit older adults and greater usage of information communication technologies to promote civic engagement among older people and, thus, positively influence their health and well-being.  相似文献

The paper develops some objective priors for correlation coefficient of the bivariate normal distribution. The criterion used is the asymptotic matching of coverage probabilities of Bayesian credible intervals with the corresponding frequentist coverage probabilities. The paper uses various matching criteria, namely, quantile matching, highest posterior density matching, and matching via inversion of test statistics. Each matching criterion leads to a different prior for the parameter of interest. We evaluate their performance by comparing credible intervals through simulation studies. In addition, inference through several likelihood-based methods have been discussed.  相似文献

ABSTRACT

Every large census operation should undergo evaluation programs to find the sources and extent of inherent coverage errors. In this article, we briefly discuss the statistical methodology to estimate the omission rate in Indian census using dual-system estimation (DSE) technique. We have explicitly studied the correlation bias factor involved in the estimate, its extent, and consequences. A new potential source of bias in the estimate is identified and discussed. During the survey, more efficient enumerators compared to the census operations are appointed, and this fact may inflate the dependency between two lists and lead to a significant bias. Some examples are given to demonstrate this argument in various plausible situations. We have suggested one simple and flexible approach which can control this bias. Our proposed estimator can efficiently overcome the potential bias by achieving the desired degree of accuracy (almost unbiased) with relatively higher efficiency. Overall improvements in the results are explored through simulation study on different populations.  相似文献

This article proposes an analytical framework to explain value creation through offshore outsourcing by addressing a key question: How do firms create value by outsourcing their business functions to foreign external providers? The growing prevalence of offshore outsourcing as a dominant business practice in global business makes this question worthy of further research attention. Situated within the organizational design literature, our proposed value creation framework also draws from strategic resource management, disintegration, location-specific resourcing, and externalization (D–L–E) and contingency perspectives. Our analysis shows that firms embarking on offshore outsourcing create value by effectively managing their internal and external resources in accordance with a changing global environment. The framework has significant implications for theory and practice and suggests avenues for further research.  相似文献
