Now What Do People Know About Global Climate Change? Survey Studies of Educated Laypeople

In 1992, a mental‐models‐based survey in Pittsburgh, Pennsylvania, revealed that educated laypeople often conflated global climate change and stratospheric ozone depletion, and appeared relatively unaware of the role of anthropogenic carbon dioxide emissions in global warming. This study compares those survey results with 2009 data from a sample of similarly well‐educated laypeople responding to the same survey instrument. Not surprisingly, following a decade of explosive attention to climate change in politics and in the mainstream media, survey respondents in 2009 showed higher awareness and comprehension of some climate change causes. Most notably, unlike those in 1992, 2009 respondents rarely mentioned ozone depletion as a cause of global warming. They were also far more likely to correctly volunteer energy use as a major cause of climate change; many in 2009 also cited natural processes and historical climatic cycles as key causes. When asked how to address the problem of climate change, while respondents in 1992 were unable to differentiate between general “good environmental practices” and actions specific to addressing climate change, respondents in 2009 have begun to appreciate the differences. Despite this, many individuals in 2009 still had incorrect beliefs about climate change, and still did not appear to fully appreciate key facts such as that global warming is primarily due to increased concentrations of carbon dioxide in the atmosphere, and the single most important source of this carbon dioxide is the combustion of fossil fuels.     

Talk: Managing Large Community Sector Organisations in the 1980s and 1990s

Abstract

The community sector is a major provider of human services in Australia. It is comprised of community or private not-for-profit organisations, but is not the only industry sector where this class of organisation is found. Like an industry sector, the community sector contains some large and many small organisations. During the 1980s large community sector organisations consciously sought to improve their management and performance in a number of ways. Nonetheless their managers face further challenges in the 1990s, some of which will tempt them into competition with the more numerous small organisations in the sector.     

Evaluating Risk Communications: Completing and Correcting Mental Models of Hazardous Processes, Part II

We propose a decision-analytic framework, called the mental models approach , for evaluating the impact of risk communications. It employs multiple evaluation methods, including think-aloud protocol analysis, problem solving, and a true-false test that allows respondents to express uncertainty about their answers. The approach is illustrated in empirical comparisons of three brochures about indoor radon.     

Choice of reinforcement rates and work rates with concurrent schedules

A constrained optimisation theory or choice in concurrent schedules of reinforcement is presented. The theory posits that subjects evaluate both reinforcement rates and the work rates required to produce them and select the most highly valued combination. The chosen reinforcement rate is obtained by efficiently allocating work rate across schedules. The theory provides a unified explanation for maximisation of the overall reinforcement rate, the law of least effort, choice under Conc FR FR, Conc VR VR. Conc VI VI and Conc VI VR schedules, and choice of work rate.     

Television as a diagnostic indicator in child therapy: An exploratory study

This paper explores the relation between television viewing and clinical indicators for the mental health profession. Television viewing is seen from a systemic process perspective, based on data about children in therapy from therapists and parents. Family viewing patterns appear to be related to certain types of clinical indicators, especially attention deficit disorder and acting out. Of particular interest is the finding of a strong association between parental viewing habits and ADD on the part of children. The results suggest that television may be a useful indicator of family health for mental health practitioners and researchers.     

Service Changes in a Central-Place System: County Tipperary,Ireland, 1966–19861

Shifts occurred in the availability of rural services in a central-place system of 143 centers in County Tipperary, Ireland, between 1966 and 1986. While there were considerable changes in the degree of availability of individual services, the overall range of services remained relatively stable at the level of the central-place system. Within the hierarchy, there was some evidence of polarization with villages recording the greatest losses and major towns recording the highest increases. New services that had emerged were strongly concentrated in the larger towns at the top of the hierarchy. Aggressive rural development policies had positive effects on the stability of the overall central-place system, although these policies may have had the unintended consequence of increasing polarization within the hierarchy.
