Language rights: Moving the debate forward 总被引:1,自引:0,他引:1
Stephen May 《Journal of Sociolinguistics》2005,9(3):319-347
This article provides an overview of the current issues and challenges facing the nascent paradigm of minority language rights (MLR). It focuses on the theoretical points of dispute and tension with respect to MLR, as well as the challenges attendant upon their implementation in complex, multiethnic and multilingual contexts. The article acknowledges, but also responds to, key critiques of MLR to date. These include debates about linguistic modernisation, linguistic identities and essentialism, language and social mobility, and macro and micro language practices. In light of these debates, the article speculates about possible ways forward for the MLR paradigm. 相似文献

We develop a mathematical model to find the optimal inspection strategy for detecting a nuclear weapon (or nuclear material to make a weapon) from being smuggled into the United States in a shipping container, subject to constraints of port congestion and an overall budget. We consider an 11-layer security system consisting of shipper certification, container seals, and a targeting software system, followed by passive (neutron and gamma), active (gamma radiography), and manual testing at overseas and domestic ports. Currently implemented policies achieve a low detection probability, and improved security requires passive and active testing of trusted containers and manually opening containers that cannot be penetrated by radiography. The annual cost of achieving a high detection probability of a plutonium weapon using existing equipment in traditional ways is roughly several billion dollars if testing is done domestically, and is approximately five times higher if testing is performed overseas. Our results suggest that employing high-energy x-ray radiography and elongating the passive neutron tests at overseas ports may provide significant cost savings, and several developing technologies, radiation sensors inside containers and tamper-resistant electronic seals, should be pursued aggressively. Further effort is critically needed to develop a practical neutron interrogation scheme that reliably detects moderately shielded, highly enriched uranium. 相似文献

The UK voluntary sector operates in an arguably enabling policy context. Yet, other external environmental influences have posed major challenges for charitable organizations within the wider voluntary sector. This paper aims to rectify the current lack of empirical research on how charitable organizations have responded in terms of their strategic positioning to the changing external operating environment and policy context. It both explores the positioning strategies adopted by two contrasting British charities that deliver public services in different ways, and investigates the factors that have influenced their choice of positioning strategies. The cases studied extend our knowledge of strategic positioning in organizations other than commercial (for-profit) ones. The findings provide new evidence that charities have begun to strategically position themselves in response to both internal organizational factors and external environmental influences. Emerging lessons from the experiences of the case study organizations provide guidance to charity managers in planning and implementing strategic positioning in their organizations. The findings also underscore the need to develop theoretical and conceptual management models specific to non-profit organizations, such as charities. 相似文献

The notion of mutual benefit has been a foundational assumption for scholars who use the relationship management perspective. Although many studies have inferred that mutual benefit links to organizational outcomes, no study to date has linked quantitatively key public member perception of benefit to positive organizational results. The current investigation sought to quantify the link between respondent perception of benefit and traditional organizational outcomes such as satisfaction and behavioral intent. 相似文献

This paper presents a Bayesian non-parametric approach to survival analysis based on arbitrarily right censored data. The analysis is based on posterior predictive probabilities using a Polya tree prior distribution on the space of probability measures on [0, ∞). In particular we show that the estimate generalizes the classical Kaplanndash;Meier non-parametric estimator, which is obtained in the limiting case as the weight of prior information tends to zero. 相似文献

This study refutes negative ageist stereotypes of how older people view themselves and society by reporting on their freely expressed main hope and main fear for the future. Data were collected through a population based cross‐sectional telephone interview survey conducted in NSW in 1999/2000. Participants (n=8,881) were randomly selected community dwelling older Australians (65+). Analyses revealed that participants were more likely to express a hope than a fear, and that a sizeable proportion of their hopes and fears were focused outwardly to family, or more broadly to social and environmental issues both locally and globally. These latter hopes and fears indicate awareness, interest and concern on a wide range of issues outside self and family. Some differences by gender and age were identified but views varied considerably among individuals. These findings provide evidence to dispel the negative image of older people as a self interested undifferentiated group whose members become progressively fearful as they age, by revealing an altruistic and outwardly focused dimension. 相似文献

Suppose that a certain quantity M of money and a finite number of indivisible items are to be distributed among n people, all of whom have equal claims on the whole. Different allocations are presented using various criteria of fairness
in the special case where each player's utility function is additively separable. An allocation is “money-egalitarian-equivalent”
(MEE) if each player's monetary valuation of his or her bundle is a fixed constant. We show that there is an essentially unique
allocation that is MEE and Pareto-optimal; it is also envy-free. Alternatively, the “gain” of a player may be defined as the
difference between how the player evaluates his bundle and an exact nth part of the whole according to his numerical evaluation of the whole. A “gain-maximin” criterion would maximize the minimum
gain obtained by any player. We show that Knaster's procedure finds an allocation which is optimal under the gain-maximin
criterion. That allocation is not necessarily envy-free, so we also find the envy-free allocation that is optimal under the
gain-maximin criterion among all envy-free allocations. It turns out that, even though there exist allocations that are simultaneously
envy-free and Pareto-optimal, this optimal allocation may fail to be Pareto-optimal, and it may also violate monotonicity
criteria.

Stephen Rosen 《Long Range Planning》1974,7(2):2-7
This is the first part of an article which will appear in three sections in one in this copy and one each in the June and August editions. The three parts make up a long article which is a distillation of a series of conversations between the author and Chief Executives of a variety of well-known U.S. films. The findings of Dr. Rosen's survey are important in that they provide an informed view of Presidential perspectives on planning. 相似文献
