Demographic and Economic Changes in Remote Australia     

Bernice Kotey 《The Australian geographer》2015,46(2):183-201

Varied distribution of resources, populations and Indigenous people result in significant socio-economic differences among statistical local areas (SLAs) in remote Australia. These differences indicate that the experience of change at the height of the resources boom will differ among SLAs in the region. Using hierarchical cluster analysis with Ward's minimum variance method, four socio-economic clusters were identified among the 197 SLAs in the region. The first was the most disadvantaged, with limited resources and human capital and the highest percentage of Indigenous people. The other three clusters improved in sequence, with the fourth having the most resources with the highest employment rate and income but least number of Indigenous people. Multivariate analysis of variance with main and interaction effects showed changes in demographics, industry structure, human capital and income over the period of investigation for the region as a whole and differences in the extent of these changes among the clusters. Policy interventions in the region are suggested for each group to match its specific needs.  相似文献   

Boundary‐layer influence on the development of a mesoscale rainstorm     

Bernice Ackerman 《大气与海洋》2013,51(4):634-652

Abstract

A major convective rainstorm slowly developed in the largely barotropic warm sector of an open‐wave cyclone. Meso‐beta‐scale boundary‐layer conditions played a significant role in the location of storm development, and provided favourable thermodynamic gradients and persistently convergent flow in preferred areas. Minimal storm movement and a strong association between the surface divergence field and cloud evolution permitted the estimation of that fraction of the moisture fed into the storm from the boundary layer that was returned to the ground as rain.  相似文献   

Scale of relief growth in the forearc of the Andes of Northern Chile (Arica latitude, 18°S)

The stream profiles of rivers of northern Chile reveal two graded segments separated by 20‐km‐long knickzones. Their formation was initiated in the Late Miocene in response to surface uplift of the western flank of the Altiplano. This phase of uplift that was coeval with the shift of deformation from the Altiplano to the sub‐Andean zone caused relief to grow at the scale of the whole drainage basin. Above and beneath these knickzones, the presence of braided channels and the absence of erosion on adjacent pediplains suggest no substantial modification in the local relief. The knickzones, however, show bedrock channels, and fluvial dissection rates have exceeded erosion rates on adjacent pediplains by two orders of magnitudes. Hence, the data imply that the only geomorphic recorders of relief growth are the knickzones that currently transpose the effects of the Late Miocene phase of surface uplift from the coast to the Altiplano.  相似文献   

Enablers and Barriers to Exit of Regional Small Business Owners in Australia     

Bernice Kotey 《The Australian geographer》2016,47(2):195-214

Successful exit enables businesses to continue with minimal disruption and provides owners with financial returns on their investments. Notwithstanding considerable scholarship in economic geography on rural and regional economic fortunes, experiences of small business exit are seldom explored. In response, this study analyses the barriers and enablers of voluntary exit by regional small business owners. A qualitative research approach with deductive thematic analysis is used to assess enablers and barriers to exit for regional small businesses, drawing upon small business literature, but cognisant of economic geographic factors. Twenty small business owners in Armidale and three business brokers were interviewed. Findings indicate that firm-level factors such as exit planning, market expansion and good performance can help overcome location barriers to exit. The regional setting makes stewardship and cessation exit strategies more feasible than financial reward strategies. Barriers to exit include: the small pool of buyers, small market, dependence on few customers, and inadequate infrastructure. Lack of exit planning and tenancy disputes also hinder exit.  相似文献
