Global Environmental Justice

The term “environmental justice” carries with it a sort of ambiguity. On the one hand, it refers to a movement of social activism in which those involved fight and argue for fairer, more equitable distribution of environmental goods and equal treatment of environmental duties. This movement is related to, and ideally informed by, the second use of the term, which refers to the academic discipline associated with legal regulations and theories of justice and ethics with regard to sustainability, the environment, and ecology. It is this latter, more academic—though vast and interdisciplinary—use of the term that is the subject of this essay. However, activists who pay careful attention to the arguments offered with regard to the political, legal, social, and philosophical treatments of these issues are potentially in a stronger position with regard to their own social movement. In that way, the two uses of the term may progress hand in hand. More broadly, however, the foundational claim about which both grassroots activists and legal, ethical, and policy advocates can agree is that environmental burdens—climate change, pollution, and their associated health risks—are borne disproportionately by the poorest and most vulnerable populations, and tend to have the greatest impact on racial and ethnic minorities, no matter where they are in the world. This is what makes the empirical questions about the environment a normative question about justice

Review of Seabird Demographic Rates and Density Dependence. JNCC Report no. 552

Introduction This report presents individual species accounts for a selection of British seabirds, sea ducks, divers and grebes. Each account gathers the most up to date published estimates on the following demographic parameters: age-specific survival, age-specific productivity, age of recruitment, incidence of missed breeding, and natal and adult breeding dispersal. Particular attention has been given to regional variation in demographic rates, indicating the extent to which estimates may be applied to other less-well studied colonies. Where possible, the intrinsic and extrinsic factors that influence demographic rates are also detailed. The reported rates should enable population models that assess the impacts of offshore wind farms to be developed as reliably and realistically as possible. Where sufficient data could not be gathered using UK examples, data from colonies outside of the UK have been presented, or a proxy species has been identified. The evidence for density-dependent regulation of seabird demographic rates is also reviewed using examples from the UK, as well as non-UK studies on similar species

Patterns of Financing: A Comparison Between White- and African-American Young Firms

Based on Kauffman Firm Survey data, examines differences in start-up and follow-on capital injections into and capital use by firms with African-American and white owners. Explores how access to capital affects the racial gap in new business formation

Motion of a distinguishable impurity in the Bose gas: Arrested expansion without a lattice and impurity snaking

We consider the real time dynamics of an initially localized distinguishable impurity injected into the ground state of the Lieb-Liniger model. Focusing on the case where integrability is preserved, we numerically compute the time evolution of the impurity density operator in regimes far from analytically tractable limits. We find that the injected impurity undergoes a stuttering motion as it moves and expands. For an initially stationary impurity, the interaction-driven formation of a quasibound state with a hole in the background gas leads to arrested expansion -- a period of quasistationary behavior. When the impurity is injected with a finite center of mass momentum, the impurity moves through the background gas in a snaking manner, arising from a quantum Newton's cradle-like scenario where momentum is exchanged back-and-forth between the impurity and the background gas.Comment: v1: 13 pages, 10 figures; v2: 14 pages, 13 figures and change of titl

Derivatives of the Incomplete Beta Function

The incomplete beta function is defined as where Beta(p, q) is the beta function. Dutka (1981) gave a history of the development and numerical evaluation of this function. In this article, an algorithm for computing first and second derivatives of Ix,p,q with respect to p and q is described. The algorithm is useful, for example, when fitting parameters to a censored beta, truncated beta, or a truncated beta-binomial model.

Amending the Mental Capacity Act 2005 to provide for deprivation of liberty

This article considers the Government’s legislative proposals against the domestic law background, specifically their relationship with existing detention powers in the Mental Health Act 1983 (MHA) and the provisions already enacted by Parliament in the Mental Capacity Act 2005 (MCA) which expressly do not authorise deprivation of liberty. Consideration is given to whether the proposed amendments to the MCA create undesirable overlap with the existing detention powers under the MHA.The final part of the article questions the Government’s approach to demarcating the boundary between the two detention regimes. It proposes that if MCA detention were confined to those who lack capacity and do not object to their care, compliance with Article 5 could be achieved more simply and at less cost than under the Government’s proposed amendments to the MCA
