Copper butterfly folds wings to avoid unwanted male advances

first_img © 2010 PhysOrg.com More information: Avoiding Male Harassment: Wing-Closing Reactions to Flying Individuals by Female Small Copper Butterflies, Jun-Ya Ide, Ethology, DOI: 10.1111/j.1439-0310.2011.01912.xAbstractMales of many butterfly species persistently court and attempt to mate with females even if the females reject courtship. This male harassment almost certainly has negative effects on female fitness. Therefore, females have likely evolved strategies to avoid such encounters. To investigate the harassment avoidance strategy of females of the small copper butterfly, Lycaena phlaeas daimio, I observed the reactions of females to other individuals flying nearby in the field. In response to the conspecific butterflies, females closed their wings if they had previously been open and did not exhibit any action if the wings had been closed. Females that closed their open wings in response to a conspecific received fewer mating attempts than did females that held their wings open. These results indicate that the wing-closing behaviour of L. phlaeas females functions to deter male mating attempts. The wing-closing reaction occurred primarily in mated females. Because females of L. phlaeas copulate only once during their lives, this behaviour is not considered an indirect mate choice but rather an attempt to avoid persistent mating attempts (i.e. sexual harassment) by males. (PhysOrg.com) — In a move that females of any species would likely recognize, the small copper female butterfly has evolved a strategy of dissuading amorous males that is both effective and energy conserving; she simply closes her wings whenever they come near.

Image: Ettore Balocchi/Wikipedia. Japanese associate professor of ecological engineering, Jun-Ya Ide noticed while observing the copper butterfly Lycaena phlaeas daimio, in the wild, that at least some of the females tended to fold their brightly colored wings, or to hold still with their wings closed, whenever males of the same species flew near them (and sometimes even when butterflies from other species came by). Intrigued he devised a simple experiment to test his theory that females that had already mated were folding their wings to ward off unwanted advances by males. In a paper published in Ethology, Ide describes how when he moved a model of a copper butterfly close to an already mated female, she more often than not closed her wings, or remained still if they were already closed. In contrast, virgin females showed no such behavior, indicating that the already mated females were using wing closing as a means to dissuade males from noticing them.Since copper butterflies mate but once in their lifetime, the move makes sense for both genders; the females go un-harassed which helps to ensure their survival and allows them to conserve energy, and the males avoid wasting time and energy on already mated females, allowing them to go after just the virgins, which helps to ensure that all females in any given area are mated.Dr Ide also noted in an interview with the BBC, that over-exuberant mating behavior by males can actually harm females, damaging their delicate butterfly parts, so the wing closing is not just a way to fend off sexual advances, but a means of physical protection as well. He also pointed out that his observations in the wild, showed that the female technique actually worked, those females that closed their wings and remained still, were subjected to less harassment than did those who did not close their wings, and thus likely lived far happier, healthier and less stressful lives as a result.

British group unveils facial reading liedetector

first_img(PhysOrg.com) — A British team of researchers led by Professor Hassan Ugail of Bradford University have demonstrated a new type of lie-detector at the annual British Science Festival in Bradford. Instead of hooking people up to wires and pressure cuffs, the new system measures heat given off around the eyes and subtle facial movements that are then analyzed using a special algorithm. Ugail claims that the, as yet unnamed system, has been shown to be around 70% accurate when testing volunteers. The new system records subtle clues that people give off when lying, such as increased blood flow around the eyes, tiny lip movements or nose twitching. All of these bits of information are then fed into the computer which uses an algorithm based on the work of psychologists Paul Ekman and Walter Friesen, to give an educated guess as to whether the person being analyzed is lying.One of the major selling points of such technology would be its use in situations where the person being targeted doesn’t know they are being tested, something that traditional polygraph lie-detectors can’t do. Because the research has been backed by the UKs Border Agency, the technology will most likely be used to screen passengers at airports, and in fact, the team is currently working with government and security officials to begin testing at an unspecified UK airport in the near future.Because the tests were done with volunteers who not only knew they were being tested, but were asked to lie when answering mundane questions, Ugail believes the system will prove to be far more accurate when used in real life situations. But he also believes that as more research is done and more variables are added to the algorithm, that the system will one day prove to be as reliable as current lie-detectors, which experts believe are about 90% accurate.Ugail also acknowledges that no lie-detector can be 100% accurate as none of them actually detect lying; instead they rely on cues to make educated guesses. Though he adds that the more tools law enforcement has at its disposal, the better chance they will have of catching those with ill intent.If the new system proves to be as reliable as Ugail hopes, it might make us all safer, but it might also lead to other less noble purposes, such as employers using it in job interviews or by news people in real-time interviews, which some might construe as an invasion of privacy.

Zoologist bemoans the continuing loss of butterfly species

first_img Butterflies deceive ants using chemical strategies Butterflies hold a unique place in the world of insects, at least for humans. They do not really do anything useful, yet they consistently rate as one of the most popular of all the bugs, showing up in songs, poetry and children’s books. People simply like them because they are so beautiful. But like so many other things in life, their beauty may be ephemeral—many species have already gone extinct, and many more are headed that way.It is because of the way humans use the land, Thomas notes—we destroy their natural habitat and then cover it over with buildings, homes or crops, leaving little for butterfly larvae to eat. The adults are fine, he adds; they move from plant to plant, eating whatever they find. But the larvae for a single species depend on a certain type of plant, or maybe two. And if that plant is unavailable, the larvae die. There is another problem, Thomas points out—most species of butterfly, unlike the migrating monarchs, do not travel far—some never move any farther than a few acres. That means it does not take much to wipe them out. A single housing community, for example, can signal the end for the butterflies that once lived there. He offers some sobering statistics: In a Bavarian reserve, scientists have been tracking butterflies for almost 200 years—back in the 19th century, there were 117 species living there; today, despite efforts to save them, there are just 71. But it is not all doom and gloom. Scientists know more about butterflies than just about any other type of insect, and one thing they have learned is that to save them, all it takes is the proper mix of vegetation and sometimes ants. And better yet, it can be done in conjunction with human settlements—people can find out which types of butterflies could or used to live in their area, figure out what sorts of plants their larvae need, and then simply plant those in their yards—then invite local butterfly groups to bring some over.

More information: J. A. Thomas. Butterfly communities under threat, Science (2016). DOI: 10.1126/science.aaf8838SummaryButterflies are better documented and monitored worldwide than any other nonpest taxon of insects (1). In the United Kingdom alone, volunteer recorders have sampled more than 750,000 km of repeat transects since 1976, equivalent to walking to the Moon and back counting butterflies (2). Such programs are revealing regional extinctions and population declines that began before 1900 (3, 4). In a recent study, Habel et al. report a similar story based on inventories of butterflies and burnet moths since 1840 in a protected area in Bavaria, Germany (5). The results reveal severe species losses: Scarce, specialized butterflies have largely disappeared, leaving ecosystems dominated by common generalist ones. Similar trends are seen across Europe (6) and beyond, with protected areas failing to conserve many species for which they were once famed. © 2016 Phys.orglast_img read more

New polymer improves power output of triboelectric nanogenerators

first_img As computerized devices have grown smaller, it has become apparent that the natural progression is for some of them to evolve to an embedded form. Toting a phone around is useful, but a better approach might be one that doesn’t require holding or otherwise keeping track of it. That leads to the problem of how to attach and power such devices. While work continues toward bendable devices that can be attached to skin or clothes, other research involves charging such devices using various kinds of generators—some might capture the energy expended in body movement, for example. Others might capture electricity that is generated by movement between objects or material, i.e., static electricity. Such devices are called triboelectric nanogenerators. Unfortunately, such work to date has led to products that are not capable of generating enough charge to power the devices that would rely on them. In this new effort, the researchers in Korea have found a way to improve power output by replacing one of its basic materials with a new polymer.To create and capture the power in static electricity, friction is generated between two materials, which results in the release of electrons that are absorbed by another material. Research into using such devices centers on the materials that are used, but thus far, it has been difficult to find materials that create a lot of charge but do not wear out quickly, and have uniformity of contact humidity resistance. The new polymer, the researchers report, is able to accept more charges from an electrode, which increases power output. The new polymer reportedly doubled the dielectric constant and also doubled the density of the charge—the researchers found power output to be 20 times higher than other devices currently being developed.The group acknowledges that more work needs to be done to address other issues with triboelectric nanogenerators, but believe their work will lead to a useable product someday soon. (Phys.org)—A team of researchers with members from several institutions in South Korea has developed a new polymer that is able to improve the power output of triboelectric nanogenerators. In their paper published on the open access site Science Advances, the researchers describe the new polymer and how well it works when used in triboelectric nanogenerators.

The copolymer is mainly composed of α phases with enhanced dipole moments due to the π-bonding and polar characteristics of the ester functional groups in the PtBA, resulting in the increase of dielectric constant values by approximately twice, supported by Kelvin probe force microscopy measurements. This increase in the dielectric constant significantly increased the density of the charges that can be accumulated on the copolymer during physical contact. The nanogenerator generates output signals of 105 V and 25 μA/cm2, a 20-fold enhancement in output power, compared to pristine PVDF–based nanogenerator after tuning the surface potential using a poling method. The markedly enhanced output performance is quite stable and reliable in harsh mechanical environments due to the high flexibility of the films. On the basis of these results, a much faster charging characteristic is demonstrated in this study.center_img Explore further Photographs of a flexible PVDF-Gn film after it was peeled off and a PVDF-Gn–based TENG.

Reviving the musical tradition of Punjab

first_imgDespite the roaring popularity of pop and Bollywood music in India, there is no dearth of art lovers who yearn to listen to the traditional, folk and classical genres in music. The upcoming music festival Traditional Music of Punjab is set to offer a cultural treat for those music lovers.If one talks about the cultural heritage of Punjab, the mellifluous kheyal ‘bandishes’ (Compositions) cannot be left out from the discourse. In fact, this is a genre of ‘Gayeki’ which has enriched the Hindustani Classical music for more than two centuries now.  Also Read – ‘Playing Jojo was emotionally exhausting’Punjabi Academy, Govt. of Delhi, Department of Art, Culture & Languages, Govt. of Delhi; organises a festival of the Traditional Music of the Punjab, which will bring together renowned artists of this genre on the May 21 – 22, at the India International Centre.The festival will begin with a performance by Bhai Balwant Singh Namdhari who will render kheyal gayeki accompanied by the tabla mridang in the traditional style of the Punjab. His performance will be followed by Raza Ali Khan grandson of the legendary Bade Ghulam Ali Khan Saheb who will sing the traditional Punjabi kheyal bandishes.  Also Read – Leslie doing new comedy special with NetflixThe second day will have Qutubi Qawwal from the Dargah of Hazrad Qutbudin Bakhtiar Kaki who will present Sufi qawwali from the Punjab. Pandit Yashpaul will render Punjabi kheyal bandishes of archival value.Before the advent of Kheyal, there were four famous Gharanas of Dhrupad singing in the Punjab, Talwandi, Haryana, Sham Chaurasi and Kapurthala. Kheyal Gayeki emerged as the next stage of evolution in the history of Hindustani music. As the strict discipline of earlier days gave way to greater expansiveness and liberty of expression in the musical firmament.  The process of this evolution had started with the creative endeavors of Amir Khusroe in the 12th century and completed itself under the vibrant outpourings of Niamat Khan Sadarang and Ferozkhan Adaran who gave the Kheyal style its present identity. Kheyal Gayeki remained confined to Delhi for some time, and it was only later during the 19th century that the new style reached the Punjab. Jarnail Ali Baksh and Kaptaan Fateh Ali founded the Patiala Gharana of Music, from which flows an important line of Kheyal Gayeki of the Punjab. “Punjab has always been renowned for its beautiful ‘bandishes’ which have enriched the repertoire of Hindustani Classical Music. Punjabi is the only other language, apart from Braj Bhasha, in which kheyal bandishes have been written over the centuries. Shah Sada Rang and Ada Rang, creators of the Kheyal style of Hindustani Classical Music, have also composed some bandishes in the Punjabi languge which will be presented in this festival. Over the last two centuries, Hindustani Musicians whether from the Punjab or elsewhere, have sung these Punjabi Kheyal compositions. It is our effort through this festival to revive an interest in them by encouraging their research and presentation. ,” says Geetanjali Gupta, Secretery, Art, Culture & Languages, Government of Delhi.“Through this annual festival, our effort is to revive an interest and attract youngsters to this beautiful form of classical music.

For animals sake celebrate a crackerfree Diwali

first_imgThe ear-splitting burst of crackers may be celebration for humans but on Diwali spare a thought for pets and strays which cringe at the pain that the deafening noise creates, say veterinarians and animal activists.Families with pets have a tough time tackling their furry friends due to crackers and pollution, which tends to scare and sometimes even traumatise them.An average human ear can hear sounds between 20 and 20,000 hertz but animals, which totally depend on their senses to survive, perceive sound almost twice that of a human ear. So, just imagine the sound of crackers — it can almost be deafening for them. Also Read – ‘Playing Jojo was emotionally exhausting’“Pets and homeless animals are at your mercy; so kindly don’t burn loud bombs,” said veterinarian Ajay Sood. “Children should not play pranks by tying crackers to their tails. Also, cats and dogs can burn their whiskers by sniffing the diyas. Keep them indoors and don’t leave them unattended. You can increase the sound of television or radio which they are accustomed to daily. This will help them to be calm during the Diwali celebrations,” Sood suggested. Also Read – Leslie doing new comedy special with NetflixHomeless animals are the most affected. They go into hiding and only come out once the festivities are over. There have been numerous incidents where children tie crackers to the tails of animals for their source of entertainment, but this is torturous for these helpless beings. “People should be a little considerate and try to avoid loud crackers. Due to Diwali celebrations, cats and dogs don’t even search for food; others suffer burn injuries that go untreated as they have no owners, and open and untreated wounds get infected, causing other severe problems for these homeless animals,” said Swati Tandon, owner of Whatspup, a pet store.Sachin Bangera, associate director, Celebrity and Public Relations, PETA India, said: “During fireworks displays, many animals become frightened by the loud noises and run away from their homes. The lucky ones end up in animal shelters and are reunited with their families, but others are never found, and some suffer serious injuries or even die as they try to escape the noise.“One should take care by keeping cats and dogs indoors during fireworks displays and if possible, stay with them.” Even celebrities are rallying for the cause. Actresses Nargis Fakhri and Jacqueline Fernandez have asked their fans to avoid crackers to provide a safe environment for pets, while Anushka Sharma, an ardent dog lover who has a pet labrador named Dude, has urged everyone to celebrate the forthcoming festival of Diwali without noise and fire crackers for the sake of animals.Through social media campaign “Pawsitive”, the Dil Dhadakne Do actress has encouraged people to reduce the use of crackers, especially in residential areas. Also, keep hospital numbers in visible places so that it is easy to reach out in case of emergency. “Ensure that your supply of pet tranquilizers is ready for some pets are so terrified that they need to be sedated. If there is a burn, wash with running water not ice. Apply a burn cream and try and contact a 24×7 vet hospital,” said Gautam Unny, another veterinarian.Also, according to Unny, the most common “emergency seen is when pets steal Diwali sweets or drink lots of ghee”!

Women with more social support live longer

first_imgElderly women who have more social support are more likely to live longer, a study claims. Researchers from George Mason University in the US examined perceived social support and its effect on cardiovascular disease (CVD) and mortality. Even after accounting for factors such as income, race, and education that could have influenced the results, the researchers still found that women in this age range who reported lower levels of social support had a higher death rate during the 10 plus years of the study. Also Read – Add new books to your shelfIn fact, they found that when women reported a very low level of social support, that predicted about a 20 per cent greater risk of death during those same 10 plus years compared to those reporting very high levels of social support. “Perceived functional social support, which we examined in this study, can include whether a person believes they could get emotional support, advice, or just company from others to do fun things with, which can help reduce stress,” said Nancy Freeborne from George Mason University. Also Read – Over 2 hours screen time daily will make your kids impulsive”It’s a reminder that sometimes the simplest things – like reaching out to a loved one – can have the most profound impact,” Freeborne said. To date, this is the largest study to explore the impact of perceived social support on cardiovascular disease and mortality, researchers said. The data from over 90,000 postmenopausal women aged 50-79 was collected over a period of 10 years. Previous studies have also shown that social support can help decrease the risk of CVD, with the new study the largest to date look at the effect of social support on CVD and all-cause mortality in women. The researchers commented that the results show the benefits of social support for health, possibly through helping to relieve stress, although they add that further research is still needed. The researchers suggest further study to account for perceived social support delivered via social media, and to further examine age and gender differences to determine if social support has different impacts based on gender or different periods in a lifetime.last_img read more

The Solar Eclipse that Brought Two Sides to Peace

first_imgIn the late afternoon of May 28, 585 BC, a solar eclipse occurred in the Near East, right at the moment when two rival states were engaged in battle. Interpreting this heavenly disturbance as a sign, the two sides put down their weapons and stopped fighting immediately. This was the eclipse that stopped a war. At least, this is the story reported by the Greek historian Herodotus. However, modern historians have puzzled over the event for decades. Astronomical and scientific data have been compared with ancient accounts to determine the veracity of the account.References to calculable astronomical events can provide vital clues to historians seeking to uncover details about Iron Age societies that have left little trace in written or epigraphic sources.Bust of HerodotosHowever, the story of the so-called Battle of the Eclipse is not so straightforward as Herodotus’ account might suggest. According to Herodotus, in the early 6th century BC, two rival states were in conflict over land in Anatolia, in present-day Turkey.The Lydians were an important kingdom that ruled over Western Anatolia, but their expansionist aims drew them eastwards, into the territory of the Medes, who held an empire covering most of Western Iran. Both states wished to expand their territory, and they clashed in central Anatolia.Astronomers Studying an Eclipse painted by Antoine Caron in 1571.By 585 BC, the dispute had been raging for five long years, with neither side making substantial gains. This protracted stalemate was injurious to both sides. The loss of men and resources was taking its toll. Nevertheless, at the end of May, the two armies met once again for a final cataclysmic battle to determine the victor.Herodotus reports that, as the battle warmed up, “day was all of a sudden changed into night.” As they observed the eclipse, the fighters put down their weapons. The two armies began to negotiate, eager to have the conflict resolved as quickly as possible.Solar eclipse occurred in May 28, 585 BC. Photo by Fred Espenak and Jean Meeus (NASA’s GSFC) – NASA, sieheInexplicable occurrences in the sky were often interpreted as signs from the gods, and both the Lydians and Medes understood the eclipse as a sign of the gods’ displeasure at their incessant fighting.Indeed, a full solar eclipse would have had a significant effect on any observers. Eclipses are often accompanied by changes in wind speed and direction, and the growing dark can confuse birds, disturbing their circadian rhythms and causing them to circle, frantically searching for a place to roost.Columbus predicts lunar eclipse to the natives.Add to this the darkening of the sky, and it’s easy to see why the Lydians and Medes would have thought the eclipse to be a threatening omen.According to Herodotus, the two sides quickly came to terms, agreeing the boundary between the two kingdoms would be the river Halys (thought to be the modern-day river Kizilirmak).Astyages, the son of the Median ruler Cyaxares, and Aryenis, the daughter of the Lydian king Alyattes, were betrothed in order to secure the agreement and guard against any further hostilities. The eclipse had brought a peaceful end to the six-year conflict.The solar eclipse of July 28, 1851 is the first correctly exposed photograph of a solar eclipse, using the daguerreotype process.However, modern historians have discovered many inconsistencies in Herodotus’ account. Astronomical data places the eclipse at May 28, 585 BC, but other ancient sources such as Eusebius, Solinus and the Oxyrhynchus Papyrus report that Cyaxares had died by this point, and the decisive battle took place under the rule of his successor Astyages.There is no other archaeological or historical record of the battle, and some historians believe that the cessation of hostilities between the two sides took place a long time after the supposed date of the Battle of the Eclipse.Fragment from the Histories VIII on Papyrus Oxyrhynchus 2099, early 2nd century AD.Historian Kevin Leloux suggests that the two events actually took place years apart, but that they were conflated in the minds of Greek commentators such as Herodotus, who was not an eyewitness to the events. He was born 100 years later, in 485 BC.Whether his report is right or wrong, however, his framing of the battle and the eclipse reveals important details about the perspectives of 5th century Greeks on the historic war between the Lydians and Medes.Although we may never know the truth about the legendary Battle of the Eclipse, Herodotus’ storytelling has resonated over thousands of years.Read another story from us: New Evidence Proves that Humans did Indeed Hunt MammothsIt certainly would be nice to think that such astronomical events could bring about the end of major conflicts, however entrenched they might be.last_img read more

Trevor Lawrence is an Elway level prospect

first_imgTrevor Lawrence is an Elway level prospectClemson true freshman quarterback Trevor Lawrence had a breakout performance, tuning up Nick Saban’s vaunted Alabama defense for 347 yards and 3 TD’s, and Colin is all aboard the hype train.Lawrence still has 2 years left before he can enter the NFL Draft, but if he would almost certainly be the #1 overall pick if he were in this year’s draft. Colin doesn’t just see Lawrence as the best QB in his class, he puts him in on the same level as all-time prospects Andrew Luck and John Elway. With one title already under his belt, Lawrence is going to be a nightmare for opposing defenses the next couple of seasons and probably wins at least one more title before teams start tanking for his pro services.

OBJ to the Patriots Story is a Real Thing

Anderson – Los Angeles Rams Running Back; Cuttino Mobley – NBA Analyst and 14-year NBA Veteran OBJ to the Patriots story is a real thingRumors have surfaced in recent days that the Patriots nearly pulled off a midseason trade for Odell Beckham, and Colin believes the story still has legs heading into the draft. Colin thinks Belichick would prefer to spend draft picks on a proven commodity like OBJ because he’s never been good at drafting wideouts, and didn’t shy away from pulling off a similar deal with Randy Moss that worked out.Right now, New England has 12 draft picks to pony up the asking price, and it makes sense to give Brady one more superstar as he continues to inch closer to retirement.

3 Ways Retailers Should Accommodate the MobileObsessed Customer

first_imgOctober 16, 2015 Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Opinions expressed by Entrepreneur contributors are their own. Register Now » Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. 4 min read Smartphones are no longer just a trendy piece of technology. For many consumers, they’re practically an appendage. Eighty percent of 18 to 24-year-olds bring their phone to bed every night. Seventy-five percent of Americans fess up to using mobile phones while using the bathroom. And 12 percent even use their smartphones in the shower.Faced with these stats, retailers can’t be shocked that 68 percent of adults check the Internet on a smartphone while shopping to enhance their in-store experience. From comparing prices to looking up user reviews, this hybrid in-store online / purchasing experience is the new normal for retailers.This new smartphone-centric status quo isn’t such a bad thing for retailers, especially those willing to adapt their go-to-market strategy. In fact consumers who use smartphones when out shopping are 14 percent more likely to make a purchase in the store than those without, according to a study from Deloitte. And roughly half of all smartphone users surveyed said their phones have influenced their decision to buy an item in a physical store.Related: Men’s Warehouse Founder George Zimmer Wants to Change How You Rent a TuxInstead of being threatened by this new breed of buyer, retailers need to see this behavioral change as an opportunity. To stay ahead of the game, retailers need to be finding ways to share the shopping experience with a customer’s screen. Following are three tips to help create a converged online / in-store customer experience that appeals to today’s consumer.1. Make mobile payment easy.Within 72 hours of its launch, one million payment cards were activated on Apple Pay. With a mobile payment structure that is simple and secure, Apple Pay has created a new breed of shopper — one who actively seeks out retailers that accept this new form of payment. In this new environment retailers that don’t offer Apple Pay, or another form of mobile payment like Google Wallet, risk losing sales.Forrester Research projected the mobile in-person market, or people using phones to pay in-store, to be valued at $6.8 billion in 2015. This form of payment is fast and easy for consumers, but it presents a challenge for many traditional retailers who must find ways to accommodate mobile payment capabilities into brick-and-mortar locations. Those willing to make the investment should be at an advantage as more consumers demand mobile payment options.2. Make being mobile friendly your M.O.Developing a mobile-friendly website is critical for retailers to cater to this new breed of buyer. One study from comScore found that 27 percent of smartphone users read customer reviews while in the aisles of a store, 23 percent call, email or text family and friends for feedback on a purchase and 22 percent read product details on their device. Optimizing this online experience for the in-store shopper is critical for success.Related: Target Is Getting Into the Beacon GameApps also win under the new regime. Fifty-five percent of shoppers who responded to Cisco’s fifth annual retail survey said they will use a retailer’s app while shopping, and 34 percent claimed to use a third-party app for the same purpose. With a mobile app, retailers can effectively cater to customers’ needs for convenience and efficient shopping. Apps can effectively deliver special offers, or money-saving coupons once customers are in the store. Retailers can also offer utility services that would otherwise need to be researched on a customer’s own time including interactive store locating tools, information on store hours and customer service contact information.3.  Promote early device upgrades via (what else?) mobile.Mobile-friendly programs can tie a customer’s love for smartphones to her love for shopping. For example, retailers can leverage in-store trade-in programs to accelerate a customer’s device upgrade timeline. Well-timed trade-in promotions can help retailers cut through the clutter during new device launches, such as the upcoming iPhone 6s launch, while increasing foot traffic from buyers looking for money-saving specials tied to new technology investments.Retailers looking to motivate mobile-obsessed customers should look for ways to use their brand’s online presence to amplify in-store promotions, and offer customers mobile promotions that can only be redeemed in store. Promoting in-store trade-in through digital channels ensures the trade-in messages reach consumers who are tied to their smartphones, then helps to drive them in the store. Related: Gap Is Doing Everything It Can to Become Cool Againlast_img read more

Will a Robot Take My Job

first_img 6 min read Register Now » Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global We can’t stop or slow down the progression of technology. Businesses and industry will always relentlessly search for ways to increase efficiency and productivity.  In the future this will lead to the rise of more machines that can do what we do. In fact, according to an Oxford University study, 47 percent of all jobs could be automated. In the next decade, your job as it’s currently described might not even exist. Sound scary? What if I told you it’s a good thing?The future of work continues to be a topic on the rise, with social mentions up 40 percent year over year, according to an analysis by Adobe. When we talk about a future where robots accomplish all the basic tasks in society, we fail to take into account that there are so many vital roles that robots won’t ever be able to fill. Here’s an idea: Instead of worrying about a skills revolution, embrace it. Learn how to turn your humanity into a marketable asset in tomorrow’s economy.Related: 8 Companies Changing How Machine Learning Is UsedIt’s great to be human.I’m the futurist in residence at Arizona State University. As a self-described optimist, I’m a big fan of humankind. I see a more automated world as a place in which more people can embrace the creativity, curiosity and ingenuity that makes us distinctly human. Not only will leveraging your humanity provide job security in the future, it will also make the work you do more meaningful.In the current job market, we don’t focus on humanity. We focus on productivity. We focus on increasing efficiency. We focus on speed. We focus on accuracy. These are all things that have essentially turned us into machines. So, it should make perfect sense that the machines will be able to rise up and take the majority of our jobs.Related: These 5 Companies Have Added Robots to Their WorkforceSo what makes being human so great? Here’s the short list:Communication. Humans are great at communicating with other humans. You could take two people who don’t speak the same language, who come from radically different cultures, and you can put them in a room and they will begin to communicate. Humans have an incredible ability to overcome barriers in order to work together to find solutions.Creativity. We humans are good at taking disparate, unrelated pieces of information and turning them into new ideas. A machine can be programmed to find the correct answers, but it can’t come up with new questions, or design a new way to solve a problem.Adaptability. No matter how the world changes, humans have proved they are able to change with it. When early humans were threatened by predators, they built weapons. When they were cold, they covered themselves and made clothing. When they couldn’t find enough food, they learned how to grow their own. The key to survival is not how strong or fast or how big you are — it’s how easily and quickly you can adapt.By focusing on these attributes, we not only learn to accept the inevitable increase in automation, but we also use the opportunity to engage in work more suited to our natures. Adobe found sentiment about automation is trending positively, with saving time (30 percent) and big data analysis (25 percent) as the top trending topics. When robots take over the mundane but necessary tasks of running a business, humans will have the freedom to further create and explore.Related: Bill Gates Believe Robots That Steal Jobs Should Pay TaxesPrepare now for the future.There are a few things both employees and employers can do now to be ready for change. Jeff Vijungco, vice president of global talent, technology and insights at Adobe, recommends envisioning what your future will look like 10 years down the road. Think about your dream career, and plan a path to get there. Think about the skills you will need to succeed in a world where rote tasks are handled by machines.Consider that in the near future, job descriptions will become less rigid. Employers will begin looking for individuals who can take on a variety of roles. Human employees will not be expected to meet productivity and efficiency goals; employers will want their employees to take on more abstract assignments that will further the success of the company on a greater scale.Some of the skills I suggest employees should start developing now include the ability to learn, the ability to be flexible and the ability to problem solve. These build on our natural human tendencies toward creativity and adaptability, and will let you turn your instincts into marketable skills.One of the pieces of advice that I give to everybody from grade schoolers to board members of Fortune 500 companies is to always be curious. Always be asking why. We should allow ourselves to have a constant thirst for understanding.Related: Elon Musk’s Vision of the Future Includes CyborgsFostering your ability to communicate with others is another important step you can take to securing your future. Robots can’t collaborate. Humans can. If you can get along and work with a wide variety of different types of people, you are infinitely more deployable, and so more valuable to your employer. They can assign you to any team, doing any task, and they know you will be able to help build a cohesive and successful unit.Employers, meanwhile, should focus on the future of their company. Many of the most successful businesses have departments dedicated to long-term planning. Think about the specific steps you will need to take to create a positive future for your company.Employers also need to keep in mind that their employees are their most valuable asset. To encourage employees to embrace their humanity, reward that humanity. Reward them for being creativity. Encourage them to discover new solutions. Most importantly, treat them with respect. Acknowledge they have lives outside of work, and create policies that foster a healthy work-life balance. Machines don’t need validation to perform their tasks. Humans, on the other hand, can’t perform successfully if they feel overworked and underappreciated. Create an environment where employees want to succeed, and they will.Related: Emerging Ethical Concerns in the Age of Artificial IntelligencePeople build the future.Robots may become more important in the future, but they cannot create the future. Only humans have the capacity to envision and build a better world.I am an optimist. I believe that the future is built by people. The future is built by the actions of people. The future is built by corporations and companies. The future is built by organizations and communities and churches and schools and universities. People build the future.When we allow machines to handle the more mundane tasks, we get the freedom to innovate. Embrace the progression of technology so your own creativity can become your greatest asset. Opinions expressed by Entrepreneur contributors are their own.
