Risk Perceptions Toward Drinking Water Quality Among Private Well Owners in Ireland: The Illusion of Control

In rural areas where no public or group water schemes exist, groundwater is often the only source of drinking water and is extracted by drilling private wells. Typically, private well owners are responsible for the quality and testing of their own drinking water. Previous studies indicate that well owners tend to underestimate the risks of their well water being contaminated, yet little is known about why this is the case. We conducted a qualitative study by interviewing private well owners in Ireland to investigate their beliefs surrounding their water quality, which, in turn, inform their risk perceptions and their willingness to regularly test their water. Based on our findings we designed a theoretical model arguing that perceived control is central in the perceived contamination risks of well water. More specifically, we argue that well owners have the illusion of being in control over their water quality, which implies that people often perceive themselves to be more in control of a situation than they actually are. As a result, they tend to underestimate contamination risks, which subsequently impact negatively on water testing behaviors. Theoretical and practical implications are highlighted.

The Impact of Organizational Structure and Supervisory Listening Indicators on Subordinate Support,Trust, Intrinsic Motivation,and Performance

A field study of a tool manufacturing organization examined the impact of supervisory listening indicators on subordinate perceptions of support, trust, and intrinsic motivation and on subordinate performance (productivity and absenteeism). The moderating impact of organizational structure was also investigated. The results indicated that the impact of supervisory listening indicators was very different dependent upon whether the structure of the organizational work group was more mechanistic or more organic. Within the more organic portions of the organization, supportive listening indicators were positively related to production and negatively related to absenteeism. The opposite occurred within the mechanistic levels. At all levels, perceived listening increased supportiveness, trust, and intrinsic motivation, although listening for accuracy had the strongest impact.     

Five dimensions of effectiveness for nonprofit annual reports

Annual reports are an important communication device through which nonprofit entities can satisfy their duty to be accountable to donors and the public at large. The primary objective of this article is to identify best practices for annual reports based on five dimensions: completeness, accessibility, transparency, full disclosure, and relevance. This article reports on both the financial and nonfinancial content in voluntarily provided annual reports. Based on our survey, we include recommendations and examples to help nonprofit leaders improve communication with stakeholders. While many of the recommendations can be adopted at little or no additional cost, achieving the most important criterion, relevance, will require nonprofit leaders to substantially improve their reporting of organizational goals and accomplishments.     

Recent progress in mathematics and engineering on optimal graph labellings with distance conditions

The problem of radio channel assignments with multiple levels of interference can be modelled using graph theory. The theory of integer vertex-labellings of graphs with distance conditions has been investigated for several years now, and the authors recently introduced a new model of real number labellings that is giving deeper insight into the problems. Here we present an overview of the recent outpouring of papers in the engineering literature on such channel assignment problems, with the goal of strengthening connections to applications. Secondly, we present a new contribution to the theory, the formulas for the optimal span of labellings with conditions at distance two for finite complete bipartite graphs. Dedicated to Professor Frank K. Hwang on the occasion of his 65th birthday. Research supported in part by NSF grants DMS-0072187 and DMS-0302307. An early version of this paper was presented at the CTS Conference on Combinatorics and its Applications in May, 2005, at Chiao Tung University, HsinChu, Taiwan. The first author is grateful to the CTS for its support of his travel.

Peak performing organisations

The literature on organisational performance is riddled with measurement problems that cannot easily be solved. In contrast we argue that elite theory in terms of performance can be more easily measured by the win record of sports organisations. Accordingly, this article argues that certain organisational peak practices are key to understanding how peak performance is sustained. Through data collected from the top ten sports organisations in the world we introduce the embryonic theory of Peak Performing Organisations (PPO). Sustained PPO practices offer more robust outcomes than the genre of High Performing Organisations.     

4 The Physical Environment in Organizations

Abstract

We review empirical research on the physical environment in professional, organizational work settings (i.e., offices, meeting rooms, and design work spaces) from the past several decades. This research reveals no common elements of the physical environment (e.g., enclosures and barriers in work spaces, adjustable work arrangements, personalized work spaces, and ambient surroundings) that are consistently and exclusively associated with desired outcomes in these work settings. Instead, these elements are routinely associated with both desired and undesired outcomes. Based on these findings, we suggest that understanding the role of physical environments in organizations requires an understanding of common trade-offs in organizational life. Further, we suggest that the prevalence of such trade-offs is grounded in tensions that are inherent to the functions that physical environments serve (i.e., aesthetic, instrumental, and symbolic functions). We provide an outline of these tensions and trade-offs in relation to common elements of the physical environment, and suggest that researchers consider these tensions and trade-offs in their future research.
