Understanding the denial of abuses of human rights connected to sports mega-events*

Abstract

Academics debate the positive and negative consequences of hosting sports mega-events, and although there is a general recognition that doing so cannot be a panacea for solving other social issues, who wins and who loses tends to be the same. This article considers why mega-events are not more regularly resisted given the routinization of harm to local populations that they tend to invoke. It develops ideas derived from the late sociologist and criminologist Stanley Cohen concerning the relationships between, and the politics of, denial and acknowledgement, with specific attention to the role of academics, non-governmental organizations (NGOs) and the media. The article illustrates the difficulties in exposing, contesting and transforming these human rights abuses, but suggests that there are grounds for optimism as new strategies for communicating human rights abuses in connection with sports mega-events are developed.     

Achieving the Sustainable Development Goals: improving water services in cities affected by extreme weather events

Abstract

This article discusses how key risks from extreme weather events might affect progress towards meeting Sustainable Development Goals 6 and 11 in cities in developing countries. It outlines the magnitude of the existing shortfall in safe water and sanitation services, and how climate change will exacerbate existing problems. It argues that the performance of many governments thus far has lacked urgency and purpose. Unless governments in particular become more committed, with redoubled effort, the goals are unlikely to be achieved.     

A Risk-Return Analysis of a Firm's Working-Capital Position

In this paper, a method is proposed by which management is able to analyze the risk-return tradeoff for various levels of liquid assets for the firm and for different maturity compositions of its debt. Together, these factors determine its working-capital position. Certain probability concepts are employed; and information is provided about the risk of cash insolvency for alternative strategies. In addition, the opportunity costs of these strategies are determined. With the framework proposed, more rational working-capital decisions are possible. The firm is able to achieve a working-capital position that provides the appropriate margin of safety in relation to the cost involved in attaining that position     

Using an economic framework to inform management of environmental entitlements

There is much in the scientific literature dealing with methods to determine environmental water requirements in streams. However, most of these methods are suited to long‐term water resource planning and setting regulatory targets. In Australia, the environment is now recognized as a legitimate user of water with its own water entitlement. With this in mind, and in the context of a water market, transparent decisions need to be made as to how best to utilize environmental water reserves on yearly, monthly or even daily basis. Environmental water managers must identify priority flow components and environmental assets. This will call for information on environmental water requirements to be presented in a manner that informs operational decisions. This paper proposes that describing environmental requirements as a function relating to different flow levels, a relationship named here as an environmental response curve, is an important first step in making transparent decisions to achieve the best outcome from limited environmental entitlements. The environmental response curves allow the marginal benefit of water (or value of each additional ML) to the environment to be understood. This allows environmental recommendations to be more readily translated into operational rules. This is not a new environmental flows methodology. The contribution of this paper is representing existing data to allow operational decisions. This paper provides a possible way forward in representing environmental demands for operation of environmental water and highlights areas where our current knowledge falls short.

Simulating effects of hydro‐dam alteration on thermal regime and wild steelhead recruitment in a stable‐flow Lake Michigan tributary

Hydroelectric dams may affect anadromous fish survival and recruitment by limiting access to upstream habitats and adversely affecting quality of downstream habitats. In the Manistee River, a tributary to Lake Michigan, two hydroelectric dams potentially limit recruitment of anadromous rainbow trout (steelhead) by increasing tailrace water temperatures to levels that significantly reduce survival of young‐of‐year (YOY) fish. The objectives of this study were to determine whether proposed restoration scenarios (dam removals or a bottom withdrawal retrofit) would alter the Manistee River thermal regime and, consequently, improve wild steelhead survival and recruitment. Physical process models were used to predict Manistee River thermal regimes following each dam alteration scenario. Empirical relationships were derived from historical field surveys to quantify the effect of temperature on YOY production and potential recruitment of Manistee River steelhead. Both dam alteration scenarios lowered summer temperatures and increased steelhead recruitment by between 59% and 129%, but total recruitments were still low compared to other Great Lakes tributaries. Considering only temperature effects, bottom withdrawal provides the greatest promise for increasing natural steelhead recruitment by decreasing the likelihood of year‐class failures in the warmest summers. Results of this study may allow managers to evaluate mitigation alternatives for Manistee River dams during future relicensing negotiations, and illustrate the utility of physical process temperature models in groundwater‐fed rivers.
