The Cape Purvis volcano, Dundee Island (northern Antarctic Peninsula): late Pleistocene age, eruptive processes and implications for a glacial palaeoenvironment

first_imgCape Purvis is a conspicuous promontory on southern Dundee Island. It forms a prominent mesa that contrasts with the smooth, shield-like (snow-covered) topography of the remainder of the island. The promontory is composed of fresh alkaline basaltic (hawaiite) volcanic rocks compositionally similar to younger lavas on Paulet Island 5 km to the east. The outcrop is one of the youngest and northernmost satellite centres of the James Ross Island Volcanic Group. 40Ar/39Ar isotopic dating indicates that the Cape Purvis volcano is 132 ± 19 ka in age. The examined sequence probably formed as a lava-fed delta during a subglacial eruption late in the glacial period corresponding to Isotope Stage 6, when the ice sheet surface elevation was 300–400 m higher than at present. A remarkable unidirectional age progression is now evident, from volcanic centres in Prince Gustav Channel (c. 2.0–1.6 Ma), through Tabarin Peninsula (1.69–c. 1 Ma) to Cape Purvis and Paulet islands (132–few ka). The age variations are tentatively ascribed to construction of progressively younger volcanic centres at the leading edge of an easterly-opening deep fault system, although the origins of the postulated fault system are unclear.last_img read more

Whats really driving the future of retail

first_img The challenge with specific predictions is that these are susceptible to becoming obsolete fast. Future technologies are likely to make the current cutting-edge redundant, and the methods by which customers can customise products are likely to look very different in the future. However, when you take a step back, some common themes emerge from these predictions, such as convenience, customer experience, business intelligence, and personalisation. It’s these themes that will really shape the future of retail.Many specific predictions about the use of new technologies, for example, link back to the notion of providing convenience to shoppers, or learning more about customers. Predictions relating to the rising use of data and analytics are about becoming more intelligent in interactions with customers.While the specifics of each theme may change, their impact is likely to stay. For example, convenience in the future may relate to payment technologies, store opening hours, or other as yet unknown methods. Whatever the case, the drive for convenience is likely to persist.While some themes are easily identified, others are less obvious; including fragmentation, flexibility, and transparency. FragmentationAt a population level, PWC describes fragmentation as the widening gap between the “haves” and the “have nots” and the impact this has had on consumer behaviour. Similar fragmentation is driving the future of the retail industry in a number of ways. A common prediction is that retail space (including stores and centres) will become smaller. Yet some retailers are opening new flagship stores and some already large centres have been expanded. This article was originally published on The Conversation. Read the original article. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Many predictions about the “future of retailing” have been made. These range from the supposed dominance of certain technologies, to increased use of data and analytics, the rising need for personalisation and customisation, and the transformation of physical spaces. Fragmentation is also occurring at the retail level. Mega-retailers like Amazon and Alibaba are holding strong positions in many markets. At the same time small, niche and independent retailers are gaining exposure through outlets such as Etsy and 100 Squared. The major question arising from this theme is what will happen to the middle? Already department stores like Myer have struggled to find a place. They lack the range and scope of the largest retailers, but don’t have the independence and flexibility of niche operators.FlexibilityFlexibility is about retailers adapting to changing trends and consumer demands. This is clearly seen in current trends and future predictions related to personalisation and customisation.Allowing customers to customise products requires flexibility to adapt product or service offerings. At the same time, more flexibility is expected with physical spaces. Traditional large store footprints are giving way to small and flexible showrooms. A new format of “super-neighbourhood” shopping centre is expected to focus on flexibility for local communities. This theme has interesting implications for the future. How can stores and shopping centres be designed and managed to provide flexibility? How will the need for flexibility impact the already challenging relationships between retail tenants and landlords? Finally, how far can flexibility in product and service design really go? Will retailers of the future be able to let consumers design anything they want with no boundaries? TransparencyThe idea of transparency has gained a lot of attention with discussions about Facebook and Cambridge Analytica. However, a similar theme is impacting retail. Consumers have unprecedented access to information about stores, brands and products through online channels, mobile devices and consumer-to-consumer sharing. This challenges retailers to be transparent and honest with product or service offerings, as misrepresentations are easily identified. How can retailers best manage the need for transparency while still maintaining a competitive advantage? Alternatively, should retailers and shopping centres look to discourage consumer information-gathering? Or can transparency be leveraged to create mutual benefit for consumers and retailers?What next?Australian retailers have had a tough time in recent years. Online shopping is growing steadily and major international companies like Costco are also expanding. This has turned retail into a global competition.No-one really knows what the future will hold, as confident as some predictions may sound. However, considering the underlying drivers of current trends, as well as future predictions, there are some key factors to consider. The real value comes not from focusing on only one driver, or the latest buzz trend. It is important to consider how these multiple trends overlap. For example, providing more flexible services might help satisfy the need for greater customer experience, as well as convenience. Alternatively, greater transparency might help cope with the fragmentation of the industry. The challenge for the retail industry is to develop specific strategies for the future based on these driving forces.

New defence against superbug infections

first_imgTiny implanted 3-D printed scaffolds infused with antibiotics could revolutionise the way doctors prevent deadly ‘superbug’ infections post-surgery, saving lives and long hospital stays. QUT Institute of Health and Biomedical Innovation biomedical engineer Dr. Phong Tran said insertion of any foreign body whether an implant or a prosthesis such as a hip joint was recognised as a major contributing factor to infections by the bacteria Staphylococcus aureus known as “golden staph”.”Some of these bacteria have evolved into a ‘superbug’ due to exposure to sub-therapeutic levels of antibiotics,” said Dr. Tran, from QUT ARC Industrial Transformational Training Centre in Additive Biomanufacturing.”My research has found a new way to use antibiotics on a biodegradable scaffold which could be delivered inside the body at the surgery site by the surgeon as a promising way to prevent golden staph infection and its development of resistance to antibiotics.”This could allow surgeons to implant pre-made scaffolds with antibiotics in the operating theatre, which are personalised to specific patients and surgical scenarios.”Dr. Tran said this new approach could be used for other bacteria such as E-coli and Pseudomonas aeruginosa which are often found in infected implants, such as new hip joints, and prostheses. “The current method of preventing these infections is intravenous antibiotics before and after surgery or the insertion of antibiotic-containing beads during the operation.”Another traditional method is to mix antibiotic powder and polymers or ceramics before manufacturing the mixture into cement or implants to be inserted in the body.”The problem here is that many commonly used antibiotics have reduced activity when exposed to elevated heat or harsh solvents during this manufacturing process.”Our technique solves all these problems because these antibiotics will retain their full strength when they are drop-loaded from their solution on already-made scaffolds.”Dr. Tran said the research showed a promising strategy for increasing patient surgical safety and is being tested in more complex physiological-like conditions such as 3-D engineered human tissue which other members of the QUT ARC Transformational Training Centre in Additive Biomanufacturing have developed.The research was published in Materials Science and Engineering C. “Our laboratory research, using Cefazolin a common antibiotic against golden staph, has shown these scaffolds release active antibiotic for four days killing off the bacteria.”Dr. Tran said that although Staphylococci aureus and Staphylococcus epidermis were common on patients’ skin they could be deadly when they got inside a surgical wound.”What happens is that these bugs form bacterial biofilms on the surface of the implant that protect the newly embedded bacteria from the body’s own immune system, and systemic antibiotics have only very low efficiency against them,” he said.

Credit: Queensland University of Technology “When patients have an infection at an implant site, surgeons often do ‘revision surgery’ to ‘clean out’ the infection,” he said.”This new technique could allow them to tailor the type of antibiotics and doses for the specific infection and deliver it directly at the infection site, therefore it would be highly effective.””The scaffolds, too, would be made personalised to the specific surgical site and procedure.”Dr. Tran said the new 3-D scaffolds were printed with a biodegradable, medical-grade, FDA-approved polymer, and antibiotics were added by simply soaking the scaffolds in antibiotic solutions.”These scaffolds have both micro-pores and macro-pores in them,” he said.

Mobile apps might make you feel better about travelling alone but they

first_imgThe bSafe app allows your loved ones to pinpoint your location when you activate the SOS button. Credit: BSafe Explore further There are a wide variety of smartphone apps that certainly make travelling alone easier to navigate. Think offline maps, language translation, transport timetables, online ticket bookings, Uber, electronic banking, virtual private networks (VPNs, especially if using electronic banking on public Wi-Fi), and updating friends and family about one’s activities. Then there are the more specific “safety” technologies. Some of them, like the Australian government’s Smart Traveller website, allow voyagers to register their intended whereabouts in case of a natural disaster or emergency. Travellers can also keep up to date with local risk and incident alerts, which can help you to steer clear if there is an incident in the city you’re headed to. Others, like BSafe and Bugle, allow you to easily notify your emergency contacts if you feel unsafe, or do not arrive at your intended destination.But while these apps might make you feel safer, it doesn’t necessarily follow that they make you safer in reality.How risky is solo travel for women?In Australia, one in three women has experienced physical violence since the age of 15, and one in five has experienced sexual violence. Much of this violence takes place in private space. And the overwhelming majority of it is committed by men who are known to the woman victim. Often by an intimate partner, date, family member or acquaintance. The rates and patterns of violence against women are similar in many countries globally. But there are some places where both violence generally, and violence against women, happen more frequently and where travellers might be at additional risk. For example, a 2013 report of the World Health Organisation found that women in Africa were almost twice as likely as women in Europe to experience violence. Meanwhile the Australian government recommends avoiding any travel to some countries and regions within Africa, South America and the Middle East. India also features in research into countries which may be comparatively less safe for women travelling alone.But for many of the most common destinations of Australians travelling overseas, the rates and patterns of violence against women are similar to those at home. Some countries, such as Japan, have notoriously low rates of sexual violence. Although there are also well documented concerns over sexual harassment on the subway, and some claims of substantial under-reporting of sex crimes due to social taboos. Yet the point remains that statistically speaking, unless you’re travelling to a high conflict zone or your travel is to seek refuge in another country, then as a woman it is not necessarily “riskier” for you to travel solo abroad. This doesn’t mean that there is no risk, but generally speaking the risks of sexual assault or homicide from an unknown male perpetrator in a public place are low. Many women do experience street harassment, intimidation and fear from men in public, but this happens in Australia as well as abroad.’Security theatre’Women are experienced at different types of “safety work”. Many women take additional precautions to manage both their risk of violence, and their feelings of fear or safety, on a daily basis. From avoiding eye contact with unknown men in the street, to wearing headphones even without music playing, to sitting in the back seat of a taxi, to texting a friend when we are home safe. While travelling solo, this safety work might also include: providing family or friends with our itinerary before we depart, regularly checking in our location on our social media, sending location updates or any changed plans back to family or friends back home, and following along on our navigation while taking a taxi. Of course, some of these activities – which are certainly practical – can also be understood as managing fear, rather than necessarily keeping us safer. Some of them are directed only at raising the alarm should we go missing – that is presumably, after some harm has already befallen us. We engage in a kind of “security theatre” – a term famously used to refer to some counter terrorism measures that actually do little to reduce the risk of a terrorist attack, but make the public less afraid. For women, our security theatre includes practices that make us feel safer and more empowered to enter into public spaces. The right amount of panicAs legal scholar Fiona Vera-Gray rightly points out, it seems impossible to know what “the right amount of panic” is. Women are regularly blamed if they fall victim to men’s violence for not being panicked enough – in other words, for taking too much risk. But if we are too panicked it will restrict our movements and participation in the world in ways that seriously undermine our freedoms. To travel solo while female seems to require walking a tightrope of challenging gender stereotypes of women as inherently in danger and in need of protection, while also navigating a cascade of advice on how to keep safe. Ultimately, of course, no mobile app is going to prevent a violent crime by a perpetrator who chooses to enact it. But if the convenience of an all-in-one navigating, translating and incident reporting device both makes solo travel easier – and makes you feel more safe and confident – then go on, get out there! Provided by The Conversation As I was writing this article, I was fortunate enough to be at a conference in Florence, Italy. Like a growing number of women who travel overseas, whether for work or leisure, many of the trips I’ve done in recent years have been alone. And as a digital criminologist (as well as a mobile app enthusiast), I’m certainly a convert to the practical usefulness of technologies for travel.center_img Citation: Mobile apps might make you feel better about travelling alone, but they won’t necessarily make you safer (2018, October 10) retrieved 17 July 2019 from This article is republished from The Conversation under a Creative Commons license.
