"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.

The potential for indirect effects between co-flowering plants via shared pollinators depends on resource abundance, accessibility and relatedness

Co-flowering plant species commonly share flower visitors, and thus have the potential to influence each other's pollination. In this study we analysed 750 quantitative plant-pollinator networks from 28 studies representing diverse biomes worldwide. We show that the potential for one plant species to influence another indirectly via shared pollinators was greater for plants whose resources were more abundant (higher floral unit number and nectar sugar content) and more accessible. The potential indirect influence was also stronger between phylogenetically closer plant species and was independent of plant geographic origin (native vs. non-native). The positive effect of nectar sugar content and phylogenetic proximity was much more accentuated for bees than for other groups. Consequently, the impact of these factors depends on the pollination mode of plants, e.g. bee or fly pollinated. Our findings may help predict which plant species have the greatest importance in the functioning of plant-pollination networks.

Understanding the effects of crevice and galvanic corrosion for seawater desalination plants management

 This research revealed the differences that occur when two forms of corrosion occur simultaneously in comparison to the individual corrosions, crevice and galvanic. It was shown that two forms of corrosion can actually reduce the amount of damage caused in selected conditions.
