Facebooks 2FA Security Practices Violate User Privacy

first_imgRisky Business Tone Deaf ‘Ethical Rot’ Data Mining Uber Alles This latest social network contretemps is classic Facebook, said John Carroll, a media analyst for WBUR in Boston.”They will do anything to data mine their 2.2 billion users. They have absolutely no shame in manipulating people’s information to the company’s advantage,” he told TechNewsWorld.”Despite the incessant apology tours that they go on, they never essentially change the nature of what they’re doing,” Carroll pointed out.What’s more, when a gaffe is exposed, Facebook places the burden on the user — or, as in the case of 2FA phone numbers, the company acts dismissive.”Facebook didn’t even bother to mount a defense this time,” Carroll observed. “They just said this has been around for a while, as if they were a politician dismissing something as old news so they don’t have to address it head on.” Just a Bug Two-factor authentication is a technique for securing online accounts. When a user logs into an account, in addition to their user word and password, a code is sent — typically in an SMS text message to a mobile phone — that serves as an additional security layer.After Facebook introduced 2FA, it relentlessly encouraged their users to use it. Concern over its users security apparently wasn’t the only reason for the social network’s enthusiasm for 2FA.Facebook was using 2FA numbers to target advertising at users, according to reports in TechCrunch and Gizmodo.”It was not our intention to send non-security-related SMS notifications to these phone numbers, and I am sorry for any inconvenience these messages might have caused,” Facebook Chief Security Officer Alex Stamos wrote in an online post. “This was not an intentional decision; this was a bug.”Nevertheless, if a user has 2FA enabled, anyone who obtains the number associated with 2FA can use it to look up and confirm the user’s profile.center_img If the privacy flaps don’t encourage advertisers to take their business elsewhere, the changing demographics of the social network may do it.”Among young people, the group most inclined to use Facebook is lower-income young people,” said Karen North, director of the Annenberg Online Communities program at the University of Southern California in Los Angeles.”Why are people leaving? Part of it is they’re seeking new experiences, but part of it is Facebook is no longer the trusted, friendly community it was,” she said.”People talk about Facebook now in terms of its advertising and exploitation,” North told TechNewsWorld.”It also seems to be tone deaf,” she added. “After being under fire for privacy and meddling issues, you’d think it would stay away from anything that had the appearance of impropriety. But it hasn’t.” As incidents of privacy abuse mount, Facebook could be courting risk for itself and its advertisers.”Facebook is gambling on its ability to avoid regulation, especially in the U.S.,” Carroll said.”What’s protecting them is the incredibly complex infrastructure that they’ve constructed,” he told TechNewsWorld.”You wonder if politicians in the U.S. Congress have the slightest idea of how any of this works, and the extent to which Facebook is sucking up data to sell to advertisers at an accelerating pace,” Carroll said. “If they can’t understand it, there’s no way they can engineer meaningful safeguards.”Although Facebook has been in and out of hot water with politicians and regulators in the past, this latest kerfuffle may be different.”This does stand apart from many of the concerning revelations at Facebook. It is just so clearly deceptive and wrong,” Digi.me’s Green said.”I imagine regulators in Europe and even the U.S. will have far harder questions for Facebook as a result,” he continued, “and even though their quarterly advertising growth numbers are still healthy, this is definitely chipping away at the trust of advertisers.” “Two-factor authentication is usually recommended to users as a security measure to see if someone else logged into their accounts,” explained Alexander Vukcevic, director of protection labs and quality assurance at Avira, a security software company in Tettnang, Germany.”Yet when the feature is being misused by any service, it also leaves the possibility for third parties to look up users’ sensitive data, and even worse, allow them to be exposed to different threats such as phishing attacks,” he told TechNewsWorld.”Asking for something as private as your mobile number under the guise of security, and reusing it for advertising and search, is about as wily as it gets,” observed Shane Green, U.S. CEO of Digi.me, a personal data management service in Washington, D.C.”It points to the complete ethical rot at the top of the company that employees and managers could ever think something like this is acceptable,” he told TechNewsWorld.Facebook’s phone number fiasco could have general consequences for consumer security, Green noted.”It absolutely hurts the willingness of people to improve their security by undermining trust,” he said. “That’s one of the great tragedies of something like this. The consequences reverberate well beyond Facebook. It could be a consumer’s bank or health data, next time, that wasn’t properly protected.”Ironically, Stamos said as much: “The last thing we want is for people to avoid helpful security features because they fear they will receive unrelated notifications.” Facebook has undermined privacy on its network by exposing mobile phone numbers provided to secure user accounts through two-factor authentication. That’s because anyone can use the numbers to look up a user’s account. One doesn’t even have to be a Facebook member to do so.Moreover, there’s no way to opt out of the setting, although it can be limited to “friends” only.The security gaffe came to light Friday when Jeremy Burge, a UK entrepreneur, posted this tweet:For years Facebook claimed the adding a phone number for 2FA was only for security. Now it can be searched and there’s no way to disable that. pic.twitter.com/zpYhuwADMS— Jeremy Burge 🐥🧿 (@jeremyburge) March 1, 2019The alert triggered responses that ranged from concern to outrage, including this tweet by Zeynep Tufekci, an associate professor at the School of Information and Library Science at the University of North Carolina, Chapel Hill:See thread!

MIT researchers devise way to help blood cells regenerate after radiation therapy

first_imgReviewed by James Ives, M.Psych. (Editor)Oct 24 2018Patients with blood cancers such as leukemia and lymphoma are often treated by irradiating their bone marrow to destroy the diseased cells. After the treatment, patients are vulnerable to infection and fatigue until new blood cells grow back.MIT researchers have now devised a way to help blood cells regenerate faster. Their method involves stimulating a particular type of stem cell to secrete growth factors that help precursor cells differentiate into mature blood cells.Using a technique known as mechanopriming, the researchers grew mesenchymal stem cells (MSCs) on a surface whose mechanical properties are very similar to that of bone marrow. This induced the cells to produce special factors that help hematopoietic stem and progenitor cells (HSPCs) differentiate into red and white blood cells, as well as platelets and other blood cells.”You can think about it like you’re trying to grow a plant,” says Krystyn Van Vliet, the Michael and Sonja Koerner Professor of Materials Science and Engineering, a professor of biological engineering, and associate provost. “The MSCs are coming in and improving the soil so that the progenitor cells can start proliferating and differentiating into the blood cell lineages that you need to survive.”In a study of mice, the researchers showed that the specially grown MSCs helped the animals to recover much more quickly from bone marrow irradiation.Van Vliet is the senior author of the study, which appears in the October 24 issue of the journal Stem Cell Research and Therapy. The paper’s lead author is recent MIT PhD recipient Frances Liu. Other authors are Singapore-MIT Alliance for Research and Technology (SMART) postdoc Kimberley Tam, recent MIT PhD recipient Novalia Pishesha, and former SMART postdoc Zhiyong Poon, now at Singapore General Hospital.Cellular drug factoriesMSCs are produced throughout the body and can differentiate into a variety of tissues, including bone, cartilage, muscle, and fat. They can also secrete proteins that help other types of stem cells differentiate into mature cells.”They act like drug factories,” Van Vliet says. “They can become tissue lineage cells, but they also pump out a lot of factors that change the environment that the hematopoietic stem cells are operating in.”When cancer patients receive a stem cell transplant, they usually receive only HPSCs, which can become blood cells. Van Vliet’s team has shown previously that when mice are also given MSCs, they recover faster. However, in a given population of MSCs, usually only about 20 percent produce the factors that are needed to stimulate blood cell growth and bone marrow recovery.”Left to their own devices in the current state-of-the-art culture environments, MSCs become heterogeneous and they all express a variety of factors,” Van Vliet says.In an earlier study, Van Vliet and her SMART colleagues showed that she could sort MSCs with a special microfluidic device that can identify the 20 percent that promote blood cell growth. However, she and her students wanted to improve on that by finding a way to stimulate an entire population of MSCs to produce the necessary factors.Related StoriesInnovative microfluidic device simplifies study of blood cells, opens new organ-on-chip possibilitiesRobotic surgery for oropharyngeal cancer not better than radiation therapy, study findsUsing artificial intelligence to personalize the dose of radiation therapy for cancer patientsTo do that, they first had to discover which factors were the most important. They showed that while many factors contribute to blood cell differentiation, secretion of a protein called osteopontin was most highly correlated with better survival rates in mice treated with MSCs.The researchers then explored the idea of “mechanopriming” the cells so that they would produce more of the necessary factors. Over the past decade, Van Vliet and other researchers have shown that varying the mechanical properties of surfaces on which stem cells are grown can affect their differentiation into mature cell types. However, in this study, for the first time, she showed that mechanical properties can also affect the factors that stem cells secrete before committing to a specific tissue cell lineage.Usually, stem cells removed from the body are grown on a flat sheet of glass or stiff plastic. The MIT team decided to try growing the cells on a polymer called PDMS and to vary its mechanical properties to see how that would affect the cells. They designed materials that varied in both their stiffness and their viscosity, which is a measure of how quickly the material stretches when stress is applied.The researchers found that MSCs grown on materials with mechanical properties most similar that of bone marrow produced the greatest number of the factors necessary to induce HPSPCs to differentiate into mature blood cells.Better recoveryThe researchers then tested their specially grown MSCs by implanting them into mice that had had their bone marrow irradiated. Even though they did not implant any HSPCs, this treatment quickly repopulated the animals’ blood cells and helped them to recover more quickly than mice treated with MSCs grown on traditional glass surfaces. They also recovered faster than mice treated with the factor-producing MSCs that were selected by the microfluidic sorting device.”The mouse studies were models of radiation therapy commonly used to kill cancer cells in the clinic. However, these therapies are highly destructive and also destroy healthy cells as well,” Liu says. “Our mechanoprimed MSCs can help to better support and regenerate those healthy bone marrow cells faster in these mouse models, and we hope the same results would translate to humans.”Van Vliet’s lab is now performing more animal studies in hopes of developing a combination treatment of MSCs and HSPCs that could be tested in humans.”You can’t survive with a low blood cell count for very long,” she says. “If you’re able to get your complete blood cell count up to normal levels faster, you have a much better prognosis for speed of recovery.”The researchers also hope to study whether mechanopriming can induce MSCs to produce different factors that would stimulate the development of additional cell types that could be useful for treating other diseases.”You could imagine that by changing their culture environment, including their mechanical environment, MSCs could be used for administration to target several other diseases,” such as Parkinson’s disease, rheumatoid arthritis, and others, Van Vliet says.

Tweaking fitness apps to help people sustain workout routine

first_imgReviewed by James Ives, M.Psych. (Editor)Dec 7 2018Fitness apps are easy to download and can help motivate people to start workout routines, but that may not be enough to sustain those routines in the long run. However, Penn State researchers suggest there may be ways to tweak those apps to inspire a deeper commitment to a fitness routine and help users hit their fitness goals.In a study of how people used a fitness app, the researchers found that certain app features that boosted inner, or intrinsic, motivation — particularly feelings of autonomy, community and competence — boosted a user’s chance of sticking with his or her workout routine.Fitness app users often struggle with maintaining a fitness routine, according to the researchers. Rock Health, a technology and healthcare venture fund, reported that about 47.5 percent of people who started to use a health app eventually stopped participating.”A major challenge for this industry is to keep people using the app after the novelty has worn off,” said S. Shyam Sundar, James P. Jimirro Professor of Media Effects and co-director of the Media Effects Research Laboratory. “The bottom line of our project is to find ways that we think will help people sustain interest in their workouts.”The researchers, who report their findings in the journal Health Communication, said that customization features that inspire autonomy — such as the number of workouts that users can follow and the amount of personal details they added to their app — corresponded to the number of tracked workouts and the amount of weight lifted.For each workout program the user followed, the weight they lifted went up by 3.2 percent and the number of workouts they tracked went up 3.8 percent, according to lead author Maria Molina, a doctoral candidate in mass communications. She added that a unit increase in information disclosed by the user resulted in a 22.3 percent increase in tracked workouts. Similarly, when the user added more personal data to their profile, they reported lifting about 36.8 percent more weight.The researchers said that relatedness, which they measured by analyzing a few factors, including the number of people users follow and the number of people who follow the users, significantly predicted the number of workouts the users tracked and the amount of weight they lifted. However, these effects depended on gender. While the number of followers increased the amount of weight lifted for everyone, the number of people users follow increased weight lifted only among female users. The number of followers also increased the likelihood that users would reach their body fat goals, but again only for female users.Related StoriesTAU’s new Translational Medical Research Center acquires MILabs’ VECTor PET/SPECT/CTApplication of machine learning methods to healthcare outcomes researchMany healthcare workers often care for patients while sick, study finds”The number of followers and the number of people you follow in social apps, or social technology in general, may build a sense of relatedness among people who are working out,” said Molina. “In other words, they feel like other people are in the same boat as they are.”Competence — or the level of proficiency people felt using the app — also linked with their workouts. Molina said that the number of photos a user posts on his or her site is one way to measure the user’s competence. In this study, the number of photographs positively predicted how much weight the user lifted.The researchers found some differences in why men and women work out. Female users appear more concerned about their weight, while men seem motivated by increasing social recognition and competition, as well as building strength and endurance.The researchers used data from publicly available profiles on BodySpace, often referred to as the “Facebook of fitness apps.” The final sample contained about 682 profiles of people who used the app from 2003 to 2017. About 408 profiles were from male users and 255 were those of female users. About 2.8 percent of the users did not report their gender.Sundar said that the findings may help developers design fitness apps that not only increase their user-retention rates, but also keep their members motivated to continue their workout routines and reach their fitness and health goals.”What we are establishing here is that certain features that can convey your sense of relatedness with others, your autonomy and your competence are systematically associated with the workouts you perform and the percentage of goals you achieve,” said Sundar. “These are the concepts that the developers should be thinking about. What we did is reverse-engineered it, in a sense, taking existing metrics available in the app and inferring what features matched up with competence, autonomy and relatedness. Something that developers might not think to do.”Sundar added that future research may couple a questionnaire with a study of fitness apps to determine if users sense that the features are creating feelings of competence, relatedness and autonomy.

Footsteps to preventing falls

Explore further Provided by Carnegie Mellon University, Department of Civil and Environmental Engineering One of four elderly persons falls every year in the United States. With more than 37 million hospitalizations every year, roughly one million falls occur in hospitals and can lead to serious injury and even death. Patients often fall while trying to get out of bed or when they walk for longer than they are able. Nurses can’t constantly monitor individual patients because of the number of patients they attend to. Sensors can continuously monitor patients, but many only detect the fall as it happens without leaving enough time for a nurse to intervene. Citation: Footsteps to preventing falls (2018, April 5) retrieved 18 July 2019 from https://phys.org/news/2018-04-footsteps-falls.html Tissue paper sensors show promise for health care, entertainment, robotics Carnegie Mellon University civil and environmental engineering Professor Hae Young Noh is developing sensors that predict when a person is about to fall by sensing the vibrations from a person’s movement. Using signal processing and machine learning, her sensors detect the movement of a person and characterize what those movements mean: if they will exit the bed, if they will take another step, and if they will fall.Unlike other sensors that monitor patient movement or vital signs, Noh’s sensors identify the intent of a person’s movements—whether they are preparing to exit the bed or just rolling over and sitting up. These sensors, placed on the bed frame, will then alert the nurse when it predicts that a patient may be getting up, so the nurse can get to the patient in time.Just like a pebble creates waves when dropped into water, our movement and contact with objects also create waves that a sensor can detect. The sensors contain accelerometers that detect wave signals that propagate through the bedframe. They utilize signal processing methods and machine learning techniques to classify the vibration, determining whether the patient has an intent to exit or not.Highly accurate and highly sensitive, the sensors are also placed on the floor to detect when a person’s gait, or manner of walking, is deteriorating.”Some people can only walk about 10 steps,” said Noh. “And they used to be healthy, so they are going to try to take the 11th step. Because it’s over their limit, the risk for a fall increases, and it shows in the gait deterioration pattern before it actually happens. We’re trying to detect that pattern.”The sensors can locate each footstep with less than 0.34 meter of error, about the size of a foot, which allows them to detect walking speed, stride length, and step frequency—factors related to predicting fall risk. The system can also estimate individual footstep forces and left-right balance of footstep forces within 5% error of body weight. The sensors can even use the vibrational signals to detect mood, because behavioral patterns suggest how people feel. The team will soon deploy the sensors in hospitals for testing. In the future, the sensors can be used for various applications, such as animal sensing and studying gait deterioration in different populations including children and those who have genetic diseases that affect their muscle function and walking ability. Ph.D. students Mostafa Mirshekari, Jonathon Fagert, and Shijia Pan, as well as electrical and computer engineering Professor Pei Zhang also collaborate on the hospital bed sensors project.”Patients may be too shy and don’t want to worry others,” says Noh, “But information about their symptoms is sometimes critical. So, if a sensor can pick them up and notify the caregivers, families, or doctors, it could help with prevention and treatment.” read more

What can snakes teach us about engineering friction

first_img Citation: What can snakes teach us about engineering friction? (2018, May 21) retrieved 18 July 2019 from https://phys.org/news/2018-05-snakes-friction.html 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. Part of this, Abdel-Aal suggests, is because our dealings with friction have evolved by constantly trying to negate it with lubricants or maximize it with texture—but almost always in pursuit of on-off goals. Once that specific goal is reached—be it making an engine piston produce a certain amount of horsepower, or a football cleat that works on a muddy field—the work that went into it rarely contributes to a broader understanding of friction.”Design of texture is still viewed as a ‘black art’ to the effect that currently there exists a gap between available enabling texturing technologies and a conceptual texture-design paradigm,” he wrote in a review of functional surfaces. Abdel-Aal notes that such an understanding would not only improve the efficiency of these specific design challenges, but it could also inspire broader use of friction in the design of new surfaces.The guide Abdel-Aal presents takes a lot of the guesswork out of texturing and instead allows designers to make intentional choices—backed by input from the slithering tribology experts.Finding the PatternTo discern the elements that give a snake its talent for managing friction, Abdel-Aal analyzed his stash of skin samples with the detail, and attention to topography, of a cartographer plotting a map.His stock of sheddings started with a few samples from friends with a Royal python and has grown to several hundred with a little help from the Philadelphia Zoo and the Academy of Natural Sciences. Explore further Different species of snakes have evolved to manage friction in various ways, depending on their environment. Studying these variations can generate information that could guide the design of surfaces with specific fiction profiles. Credit: Drexel University It’s important to study the skin as the snake would have worn it, so when Abdel-Aal gets a new sample he first soaks it in water, to make it more durable, then turns it right-side out, since most snakes shed their skin like a hastily removed tube sock.Then he mounts it on graphing paper and scans it to create a permanent record with a visual frame of reference. From there he and his research associates can begin making detailed measurements of the shape and size of the scales, and their positioning, relative to one another and about the snake’s body.Finally, he examines the skin with a scanning electron microscope to produce an image of the microscopic features that create its texture. Snake scales have invisibly small, hair-like structures, called fibrils. Though they’re just a micron in length—about 1/100th the width of a human hair—the fibrils, and how they are arranged on the snake’s underside, are key to its ability to generate friction.The positioning of the fibrils, along with the size, shape, stiffness, and distribution of scales create a unique friction profile for each snake—which is what Abdel-Aal has worked to capture and catalogue.Reverse-Engineering SnakesWith the snake skin “mapped” Abdel-Aal’s team can tease out the significant patterns of texture features that all contribute to moving the snake along in its environment.”Adaptation to local requirements requires specialization in shape, geometry and mechanical properties of the skin building blocks,” he said. “The implications of adaptation to local conditions are intriguing because they provide a venue for decoding elements of surface design in snakes—such a process has the potential to yield many lessons applicable to the design of technological surfaces.”In addition to categorizing patterns of scales and fibril distribution about the snake’s body, Abdel-Aal’s work synthesizes volumes of research on the physics of snake movement and measures of the forces of friction exerted by the snakes as they undulate, slither, slide and side-wind.By cross-referencing these measurements with the texture profile he created for each snake, Abdel-Aal can relate the physical traits to their impact on the mechanics of the snake.For example, the scale texture and musculature of large snakes, such as boas and pythons has been optimized for rectilinear, or straight-line motion. For this type of movement to occur, the snake basically lifts part of its body and lurches forward by pushing against the ground with sections of its scales. In looking closely at these sections of the snake skin, it’s apparent that there are more fibrils on the “pushing” parts of the snake’s body, which create enough friction to allow it to slide forward on the other scales.Scales to ChevronsTo make a direct relation between the skins and engineered surfaces, Abdel-Aal reviewed research about laser-textured surfaces that conducted a similar microscopic inspection and inventory of surface features. These texturing techniques, such as laser and chemical etching, sand-blasting, and deposition, create surfaces with very specific friction profiles for things like engine cylinders and hydraulic components in machinery.But they share an important detail with the texturing found in nature. Hisham Abdel-Aal, PhD, an associate teaching professor at Drexel University has collected and studied more than 350 complete snake skins shed from 40 different species to generate the data that engineers can now use to design custom, textured surfaces.

Credit: Drexel University Abdel-Aal, a mechanical engineer with expertise in tribology, the study of friction, has been collecting and analyzing snake skins for almost a decade in an effort to comprehend and quantify the way they generate friction when they move. In a paper recently published in the Journal of the Mechanical Behavior of Biomedical Materials Abdel-Aal explains how this “natural data” can be ported into the design of commercial products that slip and stick—a process called “bio-inspired surface engineering.””Nature has informed many areas of engineering and design, but tribology is one field of study that has been somewhat overlooked when it comes to learning from nature,” said Abdel-Aal. “Snakes in particular have a lot to teach us about optimizing slip and grip. Their existence is dependent on efficiency of motion in very specific environments. The snakes we are studying today are the result of an evolutionary process that has fully adapted the micro-structure of their skin and their body structure to moving and surviving in their habitat from day one. These environments can be brutal on even our most advanced machinery, so applying what we know about snake texturing could help our technology adapt as well.”But listening to nature’s design tips requires quite a bit of translation. Abdel-Aal’s work in this area is quickly becoming the standard for helping engineers unlock the potential of snake friction control for surface design.His most recent research distills the textural traits of snake skin—gleaned from analyzing 350 complete skins shed from 40 different species—matches them with the standard features of textured industrial surfaces and suggests how this framework can be used to synthesize “smart surfaces” with new frictional capabilities.Guess and CheckThough it’s an ever-present force of nature that scientists, engineers and designers have studied and grappled with as background noise for centuries, when it comes to actually wielding friction for our uses much of our modern understanding remains shrouded in mystery. Provided by Drexel University “The basic building block in the case of both snakeskin and textured engineered surfaces is a textural element that is repeated in an array distribution,” Abdel-Aal writes. “Spacing, length, orientation and shape of denticulation is, in general, common to a particular family of snakes. Engineered surfaces, on the other hand, feature textural building blocks such as cones, dimples, and chevrons, distributed on the surface. Therefore, both types of surfaces share a common constructional origin.”The predominant physical features of the textured surfaces are microscopic channels, dimples and protrusions, which are arrayed to ensure consistent friction in a lubricated system. Engineers describe surface textures in terms of the average of the measurements of these features. So “roughness” would be quantified by averaging the height of the protrusions, calculating the total area covered by them, or determining their slenderness by comparing the protrusion’s height to the area of its base.Microscopic measurements of the snakeskin’s texture features allow Abdel-Aal to make the direct relation between fibrils and protrusions. So the same roughness measures can be applied to the snakes simply by calculating fibril height, slenderness and overall distribution on the scales.This breakthrough, Abdel-Aal asserts, makes it possible to integrate the functional patterning from a snake on engineered surfaces to create textures with predictable behaviors.Gaining Traction”For bio-inspired surface design to be effective, we needed to develop a common vocabulary to describe texturing features” Abdel-Aal writes. “We found that three main parameters seemed to translate broadly between the protrusions and dimples of textured surfaces and the fibrils of snake skin: total area of the feature, feature-to-surface ratio, protrusion/height and height-to-base ratio.”In classifying the snake skins according to these measures, an interesting pattern emerged. Many of the “recommended texturing ratios” that researchers have found through the production and testing of engineered surfaces are the same that already exist in snakes.”It’s striking that engineering research over the last 25 years came to the same design solution, in terms of customization of surface features to promote efficiency of motion, that snakes have evolved over millions of years,” Abdel-Aal said. “While it means engineers have probably arrived at the right answer, it also suggests that data from studying snakes could guide us to those conclusions much more efficiently—thus accelerating the development of new surface construction paradigms that can take advantages of the rapidly evolving manufacturing tools.”Now that Abdel-Aal’s work is allowing engineers to compare surface and snake characteristics—dimples to dimples – some have already started applying it to improve the performance of systems that depend on careful friction management.Collaborators in Colombia designed and tested a surface for a prosthetic hip joint guided by the tribological data gleaned from Abdel-Aal’s analysis of Royal Python skin. Based on the work of Abdel-Aal and his collaborators, researchers in the U. K. are developing texturing schemes for tool inserts used in dry machining of titanium. These bio-inspired insert designs maximize friction while minimizing residual heat in the process. And German engineers recently published work on snake-inspired cylinder liners that allow the surfaces to minimize friction whether its moving forward or backward.Abdel-Aal has been publishing his datasets so any engineers could use them. But he also plans to build them into an algorithm that could seamlessly fit into the surface design process.”Constructing bio-inspired surfaces has a broader goal than merely replication of bio-texturing. In essence, it seeks to extend the potential tribological benefits of reptilian surfaces to the domain of human-engineered surfaces,” Abdel-Aal writes in the journal. “Although that the field is rapidly developing there is a pressing need for more in-depth cooperation between stake holder communities. I believe this common language between biology and tribology will enable the cross-communication necessary for this cooperation.” If you want to know how to make a sneaker with better traction, just ask a snake. That’s the theory driving the research of Hisham Abdel-Aal, Ph.D., an associate teaching professor from Drexel University’s College of Engineering who is studying snake skin to help engineers improve the design of textured surfaces, such as engine cylinder liners, prosthetic joints—and yes, maybe even footwear.last_img read more

This would have an impact on media pluralism and not be necessarily positive for media outlets,” she said.El Ramly, echoing arguments often made by Google, pointed to experiments with the snippet tax in both Germany and Spain, where the search giant shut down its news aggregator overnight when the tax was adopted.”In Spain it has had a negative impact on smaller media outlets where we have seen small publishing houses actually fold as a result of not being able to use the aggregation services,” she said. Google and Facebook are among the leading opponents to a draft EU reform that would force payment from web companies for reproducing or linking to copyrighted content. Tech giants and open-internet activists, not always natural bedfellows, are fighting a proposed copyright law that returns for approval at the European Parliament on Wednesday. Web giants say they would have to use automatic filters that risk stopping even legal posts, stifling innovation and free expression.”We are not actually exaggerating when we say that the filter will have to be in place,” said El Ramly.”Bear in mind that this is not only to do with audiovisual content, which has been the focus of the debate, but rather all kinds of content including lines of code, pictures.””Let’s put it very bluntly, if the platforms have a liability to make sure that the content doesn’t show up, then anything that could be perceived as a copyright infringement would be taken down,” she said.Pressed on whether the likes of Google and Facebook must clean up their act, El Ramly insisted that focusing on US companies missed the point.”Let’s remember that it is not only about US tech. Frankly, that is slightly irrelevant to the crux of the matter, the real issues,” she said.”The platform economy has been very favourable for Europe. It’s provided for cultural diversity online, for European consumers to have more choice. We would like to see that continue.”Fervently backing the reform are traditional media and content providers in urgent search of revenue at a time when so much can be seen online for free.EU online copyright dispute: a quick guideEuropean Parliament lawmakers vote Wednesday on a proposed EU copyright law that has set artists and news companies at odds with web giants such as Google and Facebook.Here is a quick guide to key terms used in the dispute over the EU Copyright Directive.Copyright, neighbouring rightsCreators of music and movies are demanding web companies pay them for reproducing or linking to their content, based on their intellectual property rights.At the same time, news organisations are claiming the right to be paid for when their stories are posted or linked to: so-called “neighbouring rights”.Article 11: fair payNews organisations should receive “fair and proportionate remuneration” for use of their stories by “information society service providers”, according to Article 11 of the draft directive.For this, the web companies would have to negotiate licensing agreements with the news organisations. Some legal experts say this is too complex, piling new rights on top of copyright laws and licences.Article 13: policing contentArticle 13 of the plan proposes to make web companies responsible for preventing copyright infringements by users posting on their sites.Web giants say they would have to use automatic filters that risk stopping even legal posts, stifling innovation and free expression.”Error-prone censorship infrastructure… will over-block legal posts, because it can’t tell allowed uses of copyrighted material (like parodies) from infringement,” said European Parliament member Julia Reda of the Green-affiliated Pirate party.Conservative member Axel Voss proposed amendments to ensure “exceptions and limitations” and “that automated blocking of content is avoided”.Links and snippetsOpponents of the directive say it could lead to a “tax” on links to news articles online by making sites pay to link to content.Amendments drafted by Voss propose not to impose payments for the hyperlinks that users click on to get to an article.But the directive may still demand payment for reproduction of “snippets” or summaries of news stories.Value gapLeading support for the directive among artists, ex-Beatle Paul McCartney complained of a “value gap… between the value these platforms derive from music and the value they pay creators”.News publishers also use the value gap complaint: advertisers pay handsomely to put ads on web pages, they say, but companies producing articles that draw readers to those pages say they receive relatively little.

Solar panels replaced tarmac on a motorway—here are the results

Citation: Solar panels replaced tarmac on a motorway—here are the results (2018, September 21) retrieved 17 July 2019 from https://phys.org/news/2018-09-solar-panels-tarmac-motorwayhere-results.html A solar panel lying under a road is at a number of disadvantages. As it’s not at the optimum tilt angle, it’s going to produce less power and it’s going to be more prone to shading, which is a problem as shade over just 5% of the surface of a panel can reduce power generation by 50%.The panels are also likely to be covered by dirt and dust, and would need far thicker glass than conventional panels to withstand the weight of traffic, which will further limit the light they absorb. Unable to benefit from air circulation, its inevitable these panels will heat up more than a rooftop solar panel too. For every 1°C over optimum temperature you lose 0.5% of energy efficiency. As a result a significant drop in performance for a solar road, compared to rooftop solar panels, has to be expected. The question is by how much and what is the economic cost?The road test results are inOne of the first solar roads to be installed is in Tourouvre-au-Perche, France. This has a maximum power output of 420 kWs, covers 2,800 m² and costed €5m to install. This implies a cost of €11,905 (£10,624) per installed kW. While the road is supposed to generate 800 kilowatt hours per day (kWh/day), some recently released data indicates a yield closer to 409 kWh/day, or 150,000 kWh/yr. For an idea of how much this is, the average UK home uses around 10 kWh/day. The road’s capacity factor – which measures the efficiency of the technology by dividing its average power output by its potential maximum power output – is just 4%. Four years ago a viral campaign wooed the world with a promise of fighting climate change and jump-starting the economy by replacing tarmac on the world’s roads with solar panels. The bold idea has undergone some road testing since then. The first results from preliminary studies have recently come out, and they’re a bit underwhelming. In America, a company called Solar Roadways has developed a smart highway with solar panels, including sensors and LED lights to display traffic warnings about any upcoming hazards, such as a deer. It also has heating pads to melt snow in winter. Several of their SR3 panels have been installed in a small section of pavement in Sandypoint, Idaho. This is 13.9 m² in area, with an installed capacity of 1.529 KWs. The installation cost is given as $48,734 (about £37,482), which implies a cost per installed kW of €27,500 (£24,542), more than 20 times higher than the Cestas powerplant.Solar Roadway’s own estimates are that the LED lights would consume 106 MWh per lane mile, with the panels generating 415 MWh – so more than 25% of the useful power is consumed by the LEDs. This would reduce performance even further. The heating plates are also quoted as drawing 2.28 MW per lane mile, so running them for just six days would cancel out any net gain from the solar panels.And this is before we look at the actual data from the Sandypoint installation, which generated 52.397 kWhs in 6 months, or 104.8 kWhs over a year. From this we can estimate a capacity factor of just 0.782%, which is 20 times less efficient than the Cestas power plant. That said, it should be pointed out that this panel is in a town square. If there is one thing we can conclude, it’s that a section of pavement surrounded by buildings in a snowy northern town is not the best place to locate a solar installation. However, perhaps there’s a bigger point – solar roads on city streets are just not a great idea.Running out of roadRoads don’t actually represent as large an area as we assume. The UK department of transport gives a breakdown of the length of the UK’s different road types. Assuming we can clad these in solar panels, four lanes of every motorway, two lanes on the A & B roads and half a lane for C & U roads (a lot are single track roads and just won’t be suitable) we come up with a surface area of 2 billion m². Which sounds like a lot, until you realise that buildings in the UK’s urban areas occupy an area of 17.6 billion m². So just covering a fraction of the UK’s rooftops with solar panels would immediately yield more power than putting them on roads. That’s quite apart from the benefits that a more elevated position would yield for greater power generation. All of this suggests that only a small fraction of the road network would actually be suitable. And, given the relatively small size of the road network, solar roads could only ever become a niche source of power and never the shortcut to our future energy supply.

And at a cost of €360m (£321m), or €1,200 (£1,070) per installed kW, one-tenth the cost of our solar roadway, it generates three times more power. This document is subject to copyright.

Costeffective marketing campaigns on social media

first_img Companies rely on a robust social media plan to increase sales. But how do they determine the best way to spend their money and maximize their results?UConn assistant professor of operations and information management Jing Peng and three colleagues have studied the issue, and discovered that depending how popular your company’s social media message is, you should employ different strategies.For example, a company like Starbucks, which tends to be a social-media standout, would promote its products differently than, say, Allstate insurance, which doesn’t have the same passionate following.The research, titled “Network Overlap and Content Sharing on Social Media Platforms,” was published in the Journal of Marketing Research in August. Peng’s co-authors are professors Ashish Agarwal from the McCombs School of Business at the University of Texas-Austin, and Kartik Hosanagar and Raghuram Iyengar, both of the Wharton School at the University of Pennsylvania.”This research is very relevant today because marketing communication through platforms such as Twitter can enable firms to reach new customers through users’ connections, and drive the demand for their products,” Peng says, noting that previous studies have shown that content sharing among friends is highly effective in acquiring new users, as compared to direct communication from a firm.Understanding the factors that drive sharing, then, becomes key to marketing practices, he says. Prior research had addressed what is being shared and who is sharing, but Peng and his colleagues wanted to address network overlap and its impact. The extent of common connections between a sender and receiver may represent their common interests, common audience, or their content sharing practices.Understanding how the propensity of senders is linked to their network overlap can be valuable information for selecting the users best able to spread content, he says. In a directed network, like Twitter, a connection can be a “followee” (person who is being followed), follower, or mutual follower. Explore further Credit: CC0 Public Domain The researchers suggest that the network connections between two users can influence their sharing propensity in three ways:A high number of common followees suggests that the sender and receiver have similar interests and, in turn, have similar propensity to share a particular piece of content. Similarly, a higher number of common followers and common mutual followers between the sender and receiver may suggest that their other followers share similar interests or tastes.A receiver may respond differently to a message, depending if he or she shares a weak or strong tie with his or her audience, which may lead to differential effects of followers.A larger audience of common followers and common mutual followers, may suggest higher redundancy in the information received by the audience, and deter a user from sharing the content because he/she is looking for uniqueness.In their research, the authors started with a set of “seeds” (authors or users who spontaneously share content). They investigated nine brands listed by Fortune magazine as the top Fortune 500 companies using social media. They collected the tweets authored (or retweeted) by each brand over a 30-day time window around April 2016. Next, for each tweet they collected social graph information and retweeting. Their research showed that 6.4 percent of social media shares have more than one co-sender.To test their findings, the researchers collected an additional data set from Digg, a large online social news aggregation website. They focused on the sharing of 31 ads in a month. Because the Digg network is much smaller than Twitter, they were able to capture all social information about each user.They analyzed the results using a “hazards model.”The work produced three key findings:Network overlap plays a significant role in content sharing on online social networks. The propensity of a receiver to share content depends on all three measures of network overlap – followees, followers, and mutual followers – suggesting that each measure independently contributes to the sharing propensity. Sharing propensity increases more with common followers than with common mutual followers.The effects of common followers and common mutual followers are moderated by the novelty of content. The impacts are positive only when the content is relatively new, and not shared by many others. If it is already widely shared, the positive effects decrease, implying that users’ need for unique content is likely influencing their decisions.Targeting senders, while taking into account their network overlap, saves between 35 and 70 percent of the time to spread content to a fixed percentage of users.Given the results of the impact of network overlap on content sharing, the researchers suggest that user targeting can be improved by drawing on the user’s network overlap with followers.”Our results illustrate that ‘seeders’ with high network overlap should be selected only when the content is not popular,” Peng says. “In practice, the popularity of content often varies across brands. Different brands may want to target different sets of ‘seeders.’ For instance, it would be more effective for popular brands like Starbucks to target users with lower network overlap. In contrast, an insurance company that struggles for engagement may want to choose high network overlap users as ‘seeders.'”Social media platforms have become a popular medium for firms to reach and engage with customers,” he adds. “Understanding what leads to effective content sharing is at the core of cost-effective marketing campaigns.” Neutral news perceived as biased depending on who shares it Social media is the new equivalent of “word of mouth” advertising, and in the United States alone, corporate social media spending is projected to exceed $17 billion by 2019.

Why you should love roboadvisers

first_img Citation: Why you should love robo-advisers (2019, April 1) retrieved 17 July 2019 from https://phys.org/news/2019-04-robo-advisers.html Explore further © 2019 The Associated Press. All rights reserved. ‘Robo-advisor’ growth hits Wall Street money managers The success of Wealthfront and Betterment, two startups that helped launch the trend, led mainstream investment companies including Vanguard, Schwab and Fidelity to add robo-advice services in recent years. Depending on the robo-adviser, you may also have access to human financial advisers, socially responsible investments and tax-loss harvesting to help reduce tax bills.This is not, and never really was, a niche product only for tech-happy millennials. From the beginning, investors of all ages spotted the significant advantages of letting computers run their portfolios. Among them:ROBO-ADVISERS ARE CHEAPRobo-advisers—also known as automated financial advisers—use computer algorithms to invest your money and rebalance the portfolios as needed to meet your goals. Robos typically use ultralow-cost exchange-traded funds and charge annual management fees of about 0.25%, for an all-in cost that can land under 0.5%.Contrast that with traditional investment costs, which can be 1% or even more on top of the annual management fees. It’s not unusual for investors to pay 2% or more annually, once all costs are considered.This is a huge deal, since costs have an enormous impact on your ultimate returns and are among the few factors you can actually control.Let’s say you invest $10,000 and market returns average 7% over the next 30 years. If you lose 2% to fees, your investment would grow to about $45,000. But if your fees are just 0.5%, your investment could reach $70,000.ROBO-ADVISERS AREN’T CONFLICTEDRobo-advisers won’t put you in an investment that costs more or performs worse than available alternatives because they’ll earn a higher commission or a free trip to Aruba.That still happens all too often with human advisers. U.S. regulators have so far resisted calls to impose a universal fiduciary standard, which would require financial advisers to put their clients’ interests ahead of their own.Robo-adviser services aren’t perfect. The SEC in December 2018 announced a settlement with Wealthfront for making false statements about its tax-loss harvesting service. Tax-loss harvesting allows people to defer tax bills by selling a losing investment to offset the profit from a winning one. But buying a “substantially identical” investment too soon after selling a loser can cause the IRS to disallow the deduction. Wealthfront failed to properly monitor accounts against such “wash sales,” which occurred in 31% of the accounts with tax-loss harvesting over a three-year period, the SEC says.center_img But a quick scroll through the SEC’s other enforcement actions last year show that this is far from the worst thing that can happen to an investor. From billion-dollar Ponzi schemes to stockbrokers getting paid to steer people to high-cost funds, humans pose a much bigger danger to investors.INVESTMENT MANAGEMENT IS NOT FINANCIAL ADVICERobo-advisers may not be the best option for people who may panic and sell in a downturn. Those folks may need human financial advisers to hold their hands and talk them out of a bad decision. Also, you probably don’t have access to a robo option within your 401(k) – at least not yet. (Your next best option may be a target-date mutual fund, which, like a robo, does the investment allocation and rebalancing for you.)Otherwise, most people should at least consider a robo-adviser, and that’s true even if they also need financial planning advice.The distinction between investment management and true financial planning is often lost. That’s not surprising, since financial planners who give comprehensive advice often charge a percentage of the investments that they manage. So do many stockbrokers, who may offer financial advice in addition to their main business of investment management.But most investment management is a commodity, while good, individualized, comprehensive financial planning advice can be priceless—and can’t be replicated by a computer.It can make sense, in other words, to pay a premium for quality financial advice that a robot can’t offer. It doesn’t make sense to pay a premium for a service that a robot could do better. 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. Robo-advisers have been around long enough that the question is no longer whether you should turn your investment decisions over to a computer. Now the question is: Why wouldn’t you?last_img read more

Sane can be the new face of Bayern Munich Matthaus tips City

first_img“The important thing is Leroy Sane has to say 100 percent yes to Bayern Munich,” Matthaus said.”And then he will be a big star in Germany, maybe the biggest face of German football in the last years because for the money that Bayern would like spend on him, he can be the new face of Bayern Munich.”However, Guardiola doesn’t appear willing to let Sane leave without a fight, saying on Wednesday that he wants to help the winger reach his potential at City. But the 23-year-old fell out of favour with City in the back half of last season, starting just five matches in the league after January. EUROPEAN SOCCER LIVE & IN HD ON DAZN | DAZN CASane also only played a total of just seven minutes over two legs of City’s quarter-final defeat to Tottenham in the Champions League, leading to talk he could look for a move in the summer.Bayern Munich have been tipped as a potential destination for Sane, with the club’s chairman Karl-Heinz Rummenigge admitting that his side are looking to find an agreement for the Germany international. Matthaus, who starred for Bayern and Germany during his playing career, believes the conditions are there for a transfer to happen.”I really think Bayern Munich [would] like to spend a lot of money, more than €80 million (£72m/$90m),” Matthaus told ESPN. “In City he’s not happy in one way, and City is ready to give him up. But the main answer has to be from Leroy Sane. Does he like to come to Bayern Munich, yes or no?”Should Sane decide he wants to join Bayern, Matthaus believes that the club’s good relationship with its former manager will help make the transfer a reality.”When he says yes, Bayern will contact Manchester City,” Matthaus said. “There’s a good relationship between Bayern Munich’s board and Pep Guardiola and I think they will find a way.”If Sane does move to the Bundesliga champions, Matthaus believes that the sky is the limit for the winger back in his native country. Lothar Matthaus has tipped Leroy Sane to make a move to Bayern Munich, saying he could become the new face of the Bundesliga champions.Sane has proven his worth at Manchester City, having helped Pep Guardiola’s side to two Premier League titles in the last three seasons.last_img read more

Missing Interstellar Iron May Just Be Good at Hiding

first_img 15 Amazing Images of Stars Interstellar space should be filled with iron — one of the most common elements in the universe — but scientists have detected only very low amounts of it to date. Now, a new study suggests iron may not be missing, but just really good at hiding. A group of researchers proposes that interstellar iron combines with a certain type of carbon chain to form molecules called iron pseudocarbynes. But because these iron pseudocarbynes register the same signature as carbon molecules on scientists’ detection devices, the sneaky iron remained hidden, according to a statement from Arizona State University (ASU). “We are proposing a new class of molecules that are likely to be widespread in the interstellar medium,” lead author Pilarisetty Tarakeshwar, research associate professor at ASU’s School of Molecular Sciences said in the statement.These Sharks Were Too Busy to Notice a Bigger Predator Watching ThemThe unexpected twist at the end of this feeding frenzy delighted scientists.Credit: NOAA Office of Ocean Exploration and Research, Windows to the Deep 2019Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Headbutting Tiny Worms Are Really, Really Loud00:35关闭选项Automated Captions – en-US facebook twitter 发邮件 reddit 链接https://www.livescience.com/65913-missing-interstellar-iron-found.html?jwsource=cl已复制直播00:0002:2802:28  In the extremely cold temperatures of interstellar space, carbon chains might condense onto iron clusters to form these iron pseudocarbynes, they reported. Over billions of years, the iron pseudocarbynes would combine with other elements and form even more complex molecules. Tarakeshar and his team examined the structure and properties of these molecules in the lab. They used infrared spectroscopy to look at the molecule’s signature spectra, or the pattern of light that gets reflected off from them. “We calculated what the spectra of these molecules would look like, and we found that they have spectroscopic signatures nearly identical to carbon-chain molecules without any iron,” Tarakeshar said. “Previous astrophysical observations could have overlooked these carbon-plus-iron molecules.” What’s more, the iron pseudocarbynes might explain how complex molecules of carbon exist in interstellar space. Carbon chains of more than nine atoms of carbon are unstable, according to the statement. But these iron clusters might be sticking onto them and stabilizing them with their grip. The findings were published on June 26 in the Astrophysical Journal. 11 Fascinating Facts About Our Milky Way Galaxy In Images: Rising ‘Phoenix’ Aurora and Starburst Galaxies Light Up the Skies Originally published on Live Science.last_img read more

A Pair of Shipwrecked WWIIEra Submarines Just Vanished from the Sea Near

first_img Disasters at Sea: 6 Deadliest Shipwrecks More than 100 World War II-era shipwrecks decorate the seafloor around Indonesia, Malaysia and Singapore — and now, there are two fewer. According to Dutch media reports, a pair of submarines that sank off the coast of Malaysia in 1941 mysteriously vanished late last week, leaving behind only some broken scraps and ghostly outlines in the sand. The wrecked subs — Dutch vessels named HNLMS O 16 and HNLMS K XVII — also contained the remains of 79 crewmen, which are now missing. [17 Mysterious Shipwrecks You Can See on Google Earth] How does a shipwreck simply disappear? According to Dutch government officials, the subs were likely stolen by scrap-metal scavengers, who have made a habit of pilfering old wrecks from the region. As many as 40 World War II-era ships have been partially or completely dismantled by scavengers, a 2017 report by the Guardian found, resulting in the desecration of the remains of some 4,500 crewmen who went down with their ships.Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65894-dutch-wwii-era-submarines-vanished.html?jwsource=cl已复制直播00:0000:3500:35  Salvaging a shipwreck usually requires blowing the vessel apart with explosives, then spending days or weeks hauling any valuable metals up onto the surface with a crane. For their trouble, scavengers can come away with millions of dollars’ worth of steel per ransacked ship, plus other spoils, such as copper cables and phosphor bronze propellers, according to the Guardian article. Wartime shipwrecks are protected under international treaties as the unmarked graves of departed soldiers — however, that has not stopped salvagers from destroying the wrecks of the American, British, Dutch, English, Australian and Japanese vessels resting in South East Asian waters. In March 2018, Malaysian officials signed an agreement with the Dutch foreign minister to better protect Dutch war wrecks in Malaysia’s waters. (Parts of Malaysia were once under Dutch colonial rule.) The agreement followed a string of particularly serious shipwreck desecrations; in 2016, the wrecks of three Dutch warships vanished from the bottom of the Java Sea off the coast of Indonesia, along with the remains of 2,200 people, the Guardian reported.

What Are Rock Cairns

first_imgRock cairns are human-made stacks, mounds or piles of rocks. They take different forms, and have been built by cultures around the world for many different purposes. Cairns may serve as monuments, burial sites, navigational aids (by land or sea), or ceremonial grounds, among other uses. They may stand alone, in clusters, or in a network of related cairns; for example, as trail markers in a park. Larger cairns can withstand time and weather, and archaeologists believe that some examples are hundreds of years old. Rock cairns are considered cultural features, or parts of a landscape built by humans. They’re similar to works built with larger stones, such as megaliths, earthen mounds or stone geoglyphs, which are stones arranged to outline an image when seen from above. Cairns aren’t just structures — their locations may be carefully chosen, and the construction process or ceremonial use may be culturally important. Because of this, rock cairns can be “very difficult to understand without looking at a landscape scale,” said María Nieves Zedeño, an archaeologist at the University of Arizona.

The word cairn comes from Scottish Gaelic. In Scotland, burial cairns are well-known, but there are many possible uses for cairns, which vary from culture to culture. In the West, native peoples have sometimes constructed burial cairns, Zedeño said, but there’s no clear evidence for astrology-based cairn positions. Instead, at memorial sites that are sometimes confusingly called medicine wheels, a central cairn might be surrounded by other cairns that point toward important places in a person’s life. In Montana, Zedeño has studied a series of cairns built around 500 years ago by the ancestors of modern-day Blackfeet Indians to funnel herds of buffalo to their death at cliff sites called buffalo jumps. The cairn construction displays a great deal of organization and understanding of buffalo behavior. “A site could have anywhere from 500 to 5,000 cairns,” Zedeño said. “It’s very large-scale landscape engineering.” In the northeastern United States, grave sites are just one possible context for cairns, Lavin said. They take other forms, including animal effigies and split stones filled with smaller rocks that are considered portals to the underworld. There are also stone ceremonial grounds that were built in spiritually significant places, with astrological stones that marked the position of celestial bodies in the sky at the start and end of dayslong festivals. But the origin or purpose of Native American cairns or other stone features is often disputed in the region. “There are some archaeologists who think that everything is farm clearing,” Lavin said. In other words, the stones are just piles of rocks that have been pulled from an agricultural field. “There are other archaeologists, including myself, who realize that there are a diversity of features out there.” She points to records from settlers, like the accounts of Monument Mountain, as evidence that Native Americans were building stone structures in Colonial America. The question isn’t just academic. Cairns are sometimes destroyed by construction, and recognition of these sites by the government is critical to preserving their ongoing cultural value to Native Americans, Lavin said. Additional resources: center_img Trail markers and art projects While many cairn traditions are very old, one type of cairn-building feels distinctly modern. There’s a controversial trend of artistically stacking stones in the wilderness, expressly to post pictures to social media. Conservationists criticize these amateur stacks, saying they can be confused for trail markers, and lead hikers astray. They also note that these amateur piles can disturb wildlife when they’re built or fall apart and that they leave a human mark in places that should be left in a more natural state. Most of these artistic stone stacks are not easily confused with older cairns, which, over hundreds of years, have had soil and vegetation build up around the rocks. Historical cairns may be so old that they’ve sunken into the ground, have been covered in lichen, or are otherwise obscured from view. The scale is also typically different. Older cairns may be made of stones too large for a single person to easily move, or they may consist of thousands of individual rocks. For example, at a Mohican stone memorial pile at Monument Mountain, in western Massachusetts, it was customary for visitors to add a stone. The votive cairn was 18 feet long and 6 feet high when it was first described in detail by a colonist in 1762, said Lucianne Lavin, the director of research and collections at the Institute for American Indian Studies in Washington, Connecticut.

The Vikings sent a handful of their powerful elites to the afterlife in boats laden with sacrificed animals, weapons and treasure; the funeral practice dates back to the Iron Age (A.D. 550 to 800) but was used throughout the Viking age (A.D. 800 to 1050), according to a statement. These richly appointed graves have been discovered across Scandinavia. For example, archaeologists had previously found one such burial boat in Norway that had evidence of human remains and one in western Scotland that contained a slew of burial items such as an ax, a shield boss, a ringed pin, a hammer and tongs. The elites who were given such elaborate send-offs were also often buried with animals, such as stallions.Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65892-viking-burial-boats-discovered-sweden.html?jwsource=cl已复制直播00:0000:3500:35  These burial boats were typically built with overlapping wooden planks (called “clinker built”) and had symmetrical ends, a true keel and overlapping planks joined together, said Johan Anund, the regional manager for The Archaeologists, an archeological organization working with the National Historical Museums in Sweden. Archaeologists have also found other, simpler boat structures, such as logboats, which are like a dugout wide canoe, Anand told Live Science in an email. [Photos: A Man, a Horse and a Dog Found in Viking Boat Burials] The remains of the dog and the horse were nestled in the bow of the well-preserved boat, while the remains of the man were found in the stern. “We don’t know much” about the man yet, Anund said. But analysis of the skeleton will reveal how old he was, how tall he was and if he had any injuries or diseases. Anund’s group may even be able to figure out where the man grew up and where he lived for most of his life, Anund said. As for the animals buried with him, they could have been sacrificed to help the dead person on the “other side” but could also be there to show the man’s status and rank, Anund said. It’s common to find horses and dogs in such burials, but also big birds like falcons. Archaeologists also found other items on the boat such as a sword, spear, shield, an ornate comb, and leftover wood and iron nails that were likely used in its construction. The other boat was badly damaged, probably because a 16th-century medieval cellar was built right on top of it, according to the statement. Some human and animal bones were still preserved on the damaged ship, but they seem to have been moved around, making it difficult for archaeologists to say much about them, Anund said. Archaeologists discovered the ships, the well and the cellar after a plot of land outside Uppsala was marked off to become a new building for the vicarage of Gamla Uppsala parish. They excavated the boats last month and some of the finds will go on display at Gamla Uppsala museum and the Swedish History Museum in Stockholm.

Does that make women beacons of cleanliness, while men are genetically unable to see the messiness in their midst? This myth is a common explanation for why men don’t do as much housework as women. Men walk into a room and apparently can’t see the dust bunnies gathering on the floor or the piles of laundry stacked up on the couch.Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65875-why-men-do-less-housework.html?jwsource=cl已复制直播00:0000:3500:35  It lets men off the hook for not doing their fair share of the household cleaning. But in a recent study we show that men aren’t dirt-blind — they can see mess just as well as women. They are simply less severely penalized for not keeping their spaces neat and tidy. Chore inequality Despite massive gains in education and employment, women still shoulder a larger share of the housework than men. Women today spend, on average, roughly an hour and 20 minutes per day cooking, cleaning and doing laundry. About a third of that is just spent cleaning. Men, on the other hand, spend about half an hour performing these duties — and only 10 minutes scrubbing and tidying. This household chore inequality is evident over time, across professions and even when women work longer hours and make more money. Even in Sweden, where government policies are strongly geared toward promoting gender equality, women do more housework. Swedish women do two times as much daily housework than men even though women are much more likely to work full-time than in other countries. Naturally, the more time spent on chores, the less a woman has to spend on other activities like sleep, work and leisure. The same mess In our study, which was recently published in Sociological Methods and Research, we asked 327 men and 295 women of various ages and backgrounds to assess a photo of a small living room and kitchen area. By random assignment, some participants rated a photo of the room looking cluttered — dirty dishes on the counter, clothing strewn about — while others examined a much tidier version of the same room. All participants looked at the one photo they were given and then rated how messy they thought it was and how urgently it needed cleaning. The first thing we wanted to know was whether men and women respondents rated the rooms differently. Contrary to popular lore, men and women saw the same mess: They rated the clean room as equally clean and the messy room as equally messy. Differing expectations So if “dirt blindness” isn’t to blame, why do women do more housework? One argument is that social expectations are different for men and women. Women may be judged more harshly for having a less-than-spotless home, and women’s awareness of these expectations may motivate them to do more. We tested this idea by randomly telling participants that the photo they were looking at depicted either “John’s” or “Jennifer’s” living space. Then we asked them to rate Jennifer’s or John’s character — how responsible, hardworking, neglectful, considerate and likable they were — based on the cleanliness of their home. We also asked participants to assess the extent to which she or he might be judged negatively by unexpected visitors — extended family, bosses and friends — and how much responsibility they believed Jennifer or John would bear for housework if they were working full-time and living alone, working full-time and married with children, or a married, stay-at-home parent. This is where things got interesting. Participants rated the photos differently depending on whether they were told that a woman or a man lived there. Notably, respondents held higher standards of cleanliness for Jennifer than they did for John. When they were told the tidy room belonged to Jennifer, participants — regardless of gender — judged it less clean and more likely to inspire disapproving reactions from guests than when the same exact room was John’s. We’ve all heard ‘men are lazy’ Still, we did find that both men and women pay a large penalty for having a cluttered home. Compared to their tidier counterparts, both Jennifer and John received substantially more negative character ratings and were expected to garner much more negative judgments from visitors. Interestingly, John’s character was rated more negatively than Jennifer’s for having a messy home, reflecting the common stereotype that men are lazy. Yet participants did not believe John would be any more likely than Jennifer to suffer negative judgment from visitors, which suggests that the “men are lazy” stereotype does not disadvantage them in a socially meaningful way. Finally, people were more likely to believe that Jennifer would bear primary responsibility for cleaning, and this difference was especially large in the hypothetical scenario in which she or he is a full-time working parent living with a spouse. That people attribute greater responsibility for housework to women than men, even regardless of their employment situation, suggests that women get penalized more often for clutter than men do. Judge not People hold women to higher standards of cleanliness than men, and hold them more responsible for it. Some women may internalize or embrace such standards. But for many, it is unlikely a love of cleaning but rather a fear of how mess will be perceived that is the real problem — and one possible reason why many women frantically clean their home before unexpected visitors arrive. The good news is that, with enough collective willpower, old-fashioned social expectations can be changed. We could start by thinking twice before judging the state of someone’s home, especially our own.

Water crisis DMK warns of jail bharo stir across TNWater crisis DMK

first_imgJune 24, 2019 SHARE SHARE EMAIL Upping the ante against the AIADMK government in Tamil Nadu for “inefficient handling” of the water scarcity in the state, DMK president M K Stalin on Monday led a massive protest here and lambasted Chief Minister K Palaniswami for attempting to downplay the crisis.‘Yagams’ (ritualistic worships) that AIADMK leaders are conducting are to save their positions in the government and not to please the rain gods, said Stalin, while also warning of a massive ‘jail bharo’ stir if the government failed to solve the state-wide water crisis.AIADMK leader D Jayakumar, however, asserted that the protest would get no support from the people.Joining the DMK workers at the protest, Stalin dramatically raised an empty pot and asked, “Kudam Inge, Kudineer Enge?” (Pot is here, where is the drinking water)?”“The government has scarcity of funds, schemes, jobs, industries, justice, law and order, now include water. But Chief Minister K Palaniswami, his deputy O Panneerselvam and Municipal Administration Minister S P Velumani are not bothered,” the DMK chief said addressing a large group of his party cadres.“This is the situation in Tamil Nadu. The state government, which is on the Centre’s clutches, has not taken any initiative to avert such a situation,” he alleged.Terming the crisis as avoidable, Stalin said, “I am not ready to argue that ‘yagams’ are wrong. This is not something which occurred all of a sudden. I have been raising the issue of plummeting water levels in lakes in the assembly for the last one year. But no efforts were made.”He referred to the party moving a resolution earlier seeking the removal of assembly Speaker P Dhanapal and said the rituals were aimed at saving positions held by AIADMK leaders in the government.“Because, on June 28, the assembly would meet and there is no need to wait for elections for a change of government. There is a possibility even before that,” Stalin said.Hitting out at Palaniswami and Velumani for allegedly trying to downplay the crisis, Stalin asked , “Why would protests spill on to the streets if people have water for basic needs?.” Published on COMMENT Tamil Naducenter_img People waiting for water with empty plastic pots at Metro water tank taps.

They allegedly asked her to go to the hospital or college campus for using a toilet.”Their attitude was discriminatory, inhuman and illegal,” the student said in her written complaint to the Chief Proctor. She has demanded ‘immediate disciplinary action’ against the guards.On Friday, Rai said he had received the student’s complaint and met her personally to hear out her grievances.”The accused guards were summoned. They have claimed that they stopped her because she was entering a men’s toilet. We have, however, formed a panel, which includes two women officials, to probe into the matter,” Rai said. He said action would be taken based on the committee’s report.Also read | Dalit youths stripped, beaten on allegation of theft in UPAlso read | Soch badlo papa: BJP MLA’s daughter who married Dalit boy makes emotional appeal to dad on live TVAlso watch | BJP MLA’s daughter who married Dalit boy makes emotional appeal to dad on live TVFor the latest World Cup news, live scores and fixtures for World Cup 2019, log on to indiatoday.in/sports.
