A panel error correction approach to explore spatial correlation patterns of the dominant housing market in Australian capital cities

Purpose - A panel error correction model has been developed to investigate the spatial correlation patterns among house prices. This paper aims to identify a dominant housing market in the ripple down process. Design/methodology/approach - Seemingly unrelated regression estimators are adapted to deal with the contemporary correlations and heterogeneity across cities. Impulse response functions are subsequently implemented to simulate the spatial correlation patterns. The newly developed approach is then applied to the Australian capital city house price indices. Findings - The results suggest that Melbourne should be recognised as the dominant housing market. Four levels were classified within the Australian house price interconnections, namely: Melbourne; Adelaide, Canberra, Perth and Sydney; Brisbane and Hobart; and Darwin. Originality/value - This research develops a panel regression framework in addressing the spatial correlation patterns of house prices across cities. The ripple-down process of house price dynamics across cities was explored by capturing both the contemporary correlations and heterogeneity, and by identifying the dominant housing market.

"It's about freedom": contesting dominant representations of devout Muslim women in the space of the nation

Since September 11 there has been a rise of Islamophobia in Australian public discourse, matched by a growth of racialised attacks on visibly identifiable Muslims in public space. These cultural racisms have arisen in a context where Islamic religious signifiers and practices have come to be read as signs of fundamentalism, terrorism and threat to national political traditions and cultural values. In particular, the hijab has become a symbol of these tensions, with the veiled woman being read as the embodiment of a ‘repressive and fundamentalist religion’. However, as some Muslim and feminist scholars have proposed, these readings rob Muslim women of their ability to articulate the reasons why wear the veil or engage in gendered religious practices. This paper argues that this enacts a form of disembodiment, whereby Muslim womens’ ability to comfortably inhabit their bodies and assert themselves in the public sphere is limited. In particular the paper draws upon two case studies which express this disembodiment, whilst highlighting the counter-strategies that devout Muslim women are adopting to reinsert their bodies and narratives in the national frame. The first refers to the recent media backlash which followed a public lecture held at Melbourne University by Islamic organization Hikmah Way, where the audience was segregated along gender lines. The second draws upon interviews conducted with veiled Muslim women in Sydney, following the Cronulla riot. These interviews show how Muslim women are contesting dominant representations of the hijab in western popular discourse by recoding it as a signifier of religious and national identity, and as an expression of democratic freedom.

Anti-inflammatory and chondroprotectivity of dominant-negative survivan and nutraceuticals, lactoferrin and herbs

Osteoarthritis is a highly problematic and debilitating medical issues affecting over 630 million people worldwide. Current treatments include anti-inflammatory drugs and joint injections which are painful and cause systemic side effects. The present study, investigates the activity of nanoformulated bioactive proteins and herbals as potential therapeutics for chronic inflammatory arthritis.

Understanding the effects of the invasive plants on rural forest-dependent communities

Most of the studies on invasive species are disproportionately focused on their ecological effects and more investigations are needed to understand the effects of invasive plants on rural livelihoods. This study assesses the effects of the invasion of Mikania micrantha-an invasive vine-on the livelihoods of the buffer zone community forest users of Chitwan National Park, Nepal. In this study, the invasive plants are categorized based on their life-form (woody and non-woody) and mode of introduction (accidental or deliberate). The focus is on accidentally transported non-woody species. A household survey revealed that the invasion disproportionately affects the livelihoods of forest-dependent households. In addition, the livelihood effects of invasive plants are particularly determined by the suitability of the invasive plants to produce locally important forest products. © 2014 Steve Harrison, John Herbohn.

Paleoreconstruction of estuarine sediments reveal human-induced weakening of coastal carbon sinks

Human activities in coastal areas frequently cause loss of benthic macrophytes (e.g. seagrasses) and concomitant increases in microalgal production through eutrophication. Whether such changes translate into shifts in the composition of sediment detritus is largely unknown, yet such changes could impact the role these ecosystems play in sequestrating CO 2. We reconstructed the sedimentary records of cores taken from two sites within Botany Bay, Sydney - the site of European settlement of Australia - to look for human-induced changes in dominant sources of detritus in this estuary. Cores covered a period from the present day back to the middle Holocene (~6000 years) according to 210Pb profiles and radiocarbon ( 14C) dating. Depositional histories at both sites could not be characterized by a linear sedimentation rate; sedimentation rates in the last 30-50 years were considerably higher than during the rest of the Holocene. C : N ratios declined and began to exhibit a microalgal source signature from around the time of European settlement, which could be explained by increased nutrient flows into the Bay caused by anthropogenic activity. Analysis of stable isotopic ratios of 12C/ 13C showed that the relative contribution of seagrass and C 3 terrestrial plants (mangroves, saltmarsh) to detritus declined around the time of rapid industrial expansion (~1950s), coinciding with an increase in the contribution of microalgal sources. We conclude that the relative contribution of microalgae to detritus has increased within Botany Bay, and that this shift is the sign of increased industrialization and concomitant eutrophication. Given the lower carbon burial efficiencies of microalgae (~0.1%) relative to seagrasses and C 3 terrestrial plants (up to 10%), such changes represent a substantial weakening of the carbon sink potential of Botany Bay - this occurrence is likely to be common to human-impacted estuaries, and has consequences for the role these systems play in helping to mitigate climate change. © 2011 Blackwell Publishing Ltd.
