On metrics matched to the discrete memoryless channel

A sequence of metrics {D_N} is said to be additive and matched to a discrete memoryless channel (DMC) if D_N is the sum on its coordinates of N single letter metrics and if the maximum likelihood decoder for sequences of length N is a minimum D_N-distance decoder. Necessary and sufficient conditions on the transition probabilities of a DMC for the existence of a sequence of additive metrics matched to it are given. In the case of the binary channel these are shown to be equivalent to the channel being symmetric. Explicit transition probabilities are given for a large class of ternary DMCs with an associated sequence of additive matched metrics. The problem solved here may be considered a generalization of the problem of finding the DMCs matched to the Lee metric solved by Chiang and Wolf in 1971 (2).     

Understanding Leadership in Major Sporting Events: The Case of the 2005 World Aquatics Championships

The purpose of this paper was to begin understanding leadership within a major sporting event. A case study of the 2005 Fédération Internationale de Natation (FINA) World Aquatics Championships was built by means of interviews and archival material, using a multi-stakeholder perspective. Findings highlighted that core elements of upper-management level leadership in events were best described by the multiple-linkage leadership theory, which includes task commitment, ability and role clarity, work organization, cooperation and mutual trust, resources and support, and external coordination as the six intervening variables. While charismatic and transformational leadership styles surfaced as contributing to the overall success of an event, the multiple-linkage leadership theory offered a more comprehensive understanding of leadership in major sporting events from a multi-stakeholder perspective.     

The impact of an open campus program upon high school students' sense of control over their environment

Students in an experimental and a control high school were compared in the fall and spring on their Locus of Control scores. An Open Campus policy was instituted in the experimental school, which essentially gave its upperclassmen the same freedom and responsibilities as those of a community college student. The experimentals increased significantly more than controls in internal control. Students reported that the Open Campus experience led to: after school jobs, greater time to pursue own interests, feelings of freedom, autonomy, and responsibility, a decline in grades due to “goofing off,” and less time for social activities.     

The learning worker,organizations and democracy

A current turn of interest in notions of the ‘learning economy’ and the ‘learning society’ is fuelling discussions on promoting education, training and learning in contemporary organizations and workplaces. Although the education of workers has been variously theorized and practised throughout the 20th century, the current debates are marked by a prevailing economic perspective that places emphasis on constructing ‘learning organizations’ and on ‘human resource’ learning in service of organizational strategies for innovation and competitive advantage in economic activities. Critics point out that economic and managerial models scarcely attend to the human subjectivity of the learner‐worker and the worker's diverse learning interests. Broader socio‐cultural ends of worker learning such as lifelong human development and participatory citizenship in democratic society are very often overlooked. This article offers a critical discussion of current conceptions of learning organizations and learning workers. It argues that the prevailing focus on techno‐economic imperatives and of obscured managerial elite interests in organizations currently circumscribe and delimit learning in production organizations. It proposes that a more comprehensive approach to learning in organizations attends explicitly to the needs and interests of workers as learning persons. Taking a longer view, it proposes that organizational and worker learning may generate not only improved work practices but may regenerate links between lifelong learning, societal democratic citizenship and civilized organizations.     

Policy discourse analysis: negotiating gender equity

This analysis of activists' and bureaucrats' politicking for gender policy in Australia demonstrates the utility of discourse analysis. Feminist policy initiatives are special: they challenge hegemony and they circulate counter discourse. Policy elites try to manage and discredit them. Traditional policy frameworks are used to identify policy with policy mechanisms, policy communities, value shifts and the like. But the use of policy discourse analysis for this Australian story elicits key strategies for constructing and managing a counter narrative and maintaining a counter public of outsiders using insiders to institutionalize gender policies even as equity and social justice value priorities recede.
