Sarnia-Lambton Association: Wetland Treatment of Wastewater

This document describes the functions and values of wetlands, and includes keywords and illustrations. Wetlands have received wastewater discharges from many different situations in the past, but only recently have they been recognized as potentially cost-efficient treatment systems. They can effectively remove or convert large quantities of pollutants from point sources (municipal and industrial wastewaters) and non-point sources (mine, agricultural and urban runoff).

Design criteria monograph for liquid propellant gas generators

Monograph reviews and assesses current design practices, and from them establishes firm guidance for achieving greater consistency in design, increased reliability in end product, and greater efficiency in design effort. Main emphasis of monograph is on bipropellant gas generators using hydrogen peroxide and hydrazine monopropellants

Unions, Associations and Twenty-First Century Professionals

[Excerpt] Unions that represent professional and technical workers are at a critical juncture in their evolution. On the one hand, there is tremendous opportunity; disproportionate employment growth can be expected for professional and technical occupations in health care, education, science and technology, performing arts, media and communication. On the other hand, there are clear challenges. Professional labor markets and the contemporary workplace are being reconfigured by neoliberal economic policies, technological change, and the spread of contingent employment arrangements. Twenty-first century professional workers will respond positively to unions only if they see organizations that are agile enough to adapt to the workers\u27 own shifting concerns

Book review of this monograph

Skills, organisational performance and economic activity in the hospitality industry : a literature review

This monograph aims to understand the pressures which push organisations to adopt particular routes to competitive advantage. The monograph aims to discover if the best practice high skill, high wage and high quality route is used in the hospitality industry. It seeks to determine the influence of companies' product market strategies and their in-company and external structural factors on skills levels, work organisation, job design and people management systems. The monograph looked at the notion of best practice approaches and then moved on to consider the best way to carry forward the future research agenda of reviewing the nature of human resource management (HRM) in the hospitality sector. Conclusions were drawn from a range of interviews and from existing work which has sought to address the issue of HRM in the hospitality sector

Blueprint for Change: A National Assessment of Winning Union Organizing Strategies

In the last seven years the AFL-CIO has put forth an immense effort to facilitate, support, and encourage organizing initiatives by all affiliates. Although to date progress has been much slower than the leadership of the labor movement had hoped, more recently there have been some signs that those efforts are beginning to bear fruit. A growing number of unions are putting more resources into organizing, recruiting and training more organizers, running more organizing campaigns, winning more elections and voluntary recognitions, and winning them in larger units. Yet, despite all the new initiatives and resources being devoted to organizing and all the talk of changing to organize, American unions today are at best standing still. Massive employment losses in manufacturing, retail, hospitality, and airline industries have eliminated hundreds of thousands of union jobs, raising the bar even higher for the number of new workers needed to maintain current union density, much less grow. At the same time, the political climate for organizing has become ever more hostile as the threat of terrorism and the fog of war have been used to justify a full scale attack on civil liberties, federal sector unions, immigrant workers, and organizing and collective bargaining rights. Even in this climate, some unions, in some industries, have still managed to make major organizing gains, despite intensive employer opposition. In just the last several years we have witnessed significant victories such as CWA at Cingular Wireless, IFPTE at Boeing, UAW at New York University, PACE at Imerys, SEIU at Catholic Healthcare West, UNITE at Brylane, and HERE in the Las Vegas hotels. Although there was great variation in the industry, workforce, union, and company characteristics in each of these campaigns, still a pattern becomes evident—the unions that are most successful at organizing run fundamentally different campaigns, in both quality and intensity, than those that are less successful. In this paper we focus on these fundamental differences in the nature of winning and losing campaigns which provide us with a blueprint for the kinds of comprehensive organizing strategies that are required to win across a wide range of organizing environments and company and unit characteristics. We also look at the strategic, organizational, and cultural changes the U.S. labor movement must make in order to be able to mount these more comprehensive campaigns and make the gains necessary to significantly increase union density and the political and economic power that goes with it

Bulk and Boundary Invariants for Complex Topological Insulators: From K-Theory to Physics

This monograph offers an overview on the topological invariants in fermionic topological insulators from the complex classes. Tools from K-theory and non-commutative geometry are used to define bulk and boundary invariants, to establish the bulk-boundary correspondence and to link the invariants to physical observables.Comment: Monograph in Springer Series in Mathematical Physics Studies, see ISBN below.
