Decentralization: The American Experience and its Relevance for Australia

An explanation is sought for the general lack of any significant amount of decentralization in Australia. Major, ongoing trends in the decentralizing of manufacturing industries in the United States are examined, and an attempt is made to identify specific forces attracting industry to country locations and those deterring it. Detailed comparison of the American and Australian situations reveals marked differences in the presence of conditions that either promote or discourage decentralization. It is concluded that, on present indications, the outlook for decentralization in Australia remains unfavourable.     

Adaptive Approaches to Biosecurity Governance

This article discusses institutional changes that may facilitate an adaptive approach to biosecurity risk management where governance is viewed as a multidisciplinary, interactive experiment acknowledging uncertainty. Using the principles of adaptive governance, evolved from institutional theory, we explore how the concepts of lateral information flows, incentive alignment, and policy experimentation might shape Australia's invasive species defense mechanisms. We suggest design principles for biosecurity policies emphasizing overlapping complementary response capabilities and the sharing of invasive species risks via a polycentric system of governance.     

Geographical aspects of US farmland values and changes during the 1978–1992 period

Data from the US Census of Agriculture suggest important changes since 1978 in regional patterns of farmland values. This study examines these patterns with the aid of county-level maps showing average values per hectare for the Census years 1978, 1982, 1987 and 1992 and changes between these years. Farmland price increases are geographically associated with general proximity to major population centers and the presence of aesthetically attractive natural landscapes, while these two attributes in combination are generally absent in areas not experiencing price increases. The widespread phenomenon of non-commercial farming as a factor in farmland price increases is examined. It is hypothesized that such site factors as climate and soils which traditionally have helped explain higher farmland prices in some regions are of diminishing importance, while situational factors such as proximity to major population centers are in the ascendancy. The changing importance of site versus situational factors is assessed using analysis of variance tests comparing the influence on farmland values of the predominately situational differences between metropolitan, nonmetropolitan-adjacent and nonmetropolitan-nonadjacent settings, versus the predominately site differences between major agricultural regions.     

The Effects of Average Fundamental Frequency and Variance of Fundamental Frequency on Male Vocal Attractiveness to Women

This paper employs a cue synthesis experimental method to examine the effects of pitch and intonation on male vocal attractiveness to women. Voices were acoustically manipulated to yield nine combinations of three levels of average fundamental frequency and three levels of variance of fundamental frequency. Strong main effects were obtained for the average fundamental frequency manipulation, with high voices rated as significantly less attractive to women than either medium or low voices, which do not differ in attractiveness. The main effects of manipulations of variance of fundamental frequency on vocal attractiveness and benevolence did not reach significance, but there was a significant interaction on the benevolence factor, with high or low average fundamental frequency manipulations being rated particularly low for voices with low variance of fundamental frequency.
