Statistical analysis could predict bankrupt stocks

center_img Investors who ‘gamble’ in the stock market have same characteristics as lottery players The physicists, from Boston University in Boston, Massachusetts, and Fudan University in Shanghai, China, have published their study in a recent issue of EPL.“On the basis of statistical analysis, we satisfactorily distinguish the evident difference between bankrupting and non-bankrupting stocks,” coauthor Jiping Huang of Fudan University told Phys.org. “This shows that it is possible to develop a statistical-analysis-based early warning system to forecast the time of bankruptcy. The system depends on stock prices, rather than corporate internal financial information.”For many decades, researchers and analysts have attempted to develop models for predicting corporate bankruptcy, but most of these models depend on the availability of detailed internal financial information about the corporation, which is often difficult to obtain. Here, the scientists have attempted to predict a corporation’s risk of bankruptcy by observing the market dynamics of its stock price.

Ricoh shows off omnidirectional camera w video

first_img © 2013 Phys.org “When viewing it like a regular panoramic image, you can also see up and down. When you pull out from the image, it finally becomes a circle, and you can also look at it as a sphere,” he commented.The fun elements of such spherical panoramic photos and their easy integration within creative displays are not lost on Ricoh’s creators. The camera is still in design phase; Asahina said not all of its features have been finalized. Although “the specs have not been decided yet,” the Ricoh team is discussing the project “with staff at art colleges,” he said. The technology, he added, could be presented as a “panorama ball” where the pictures are stuck onto the sphere.

Explore further (Phys.org)—A novel panoramic camera from Ricoh is under development and it is described as a step beyond compact and single-lens reflex (SLRs) cameras. Takaharu Asahina of the New Business Development Center, Ricoh, told DigInfo TV about the company’s concept of an omnidirectional camera prototype. The camera shoots entire 360-degree panorama images with just one pass, just one click, and can then send them over to the user’s mobile device, such as tablet or phone, via Wi-Fi. The camera has two fish-eye lenses, each covering 180 degrees. Asahina said the Ricoh device can only take still photos, but its creators are interested in continuing the project to enable it to take video too. “We’d like to commercialize it, and make it a bit smaller. We want to keep developing it, so we can offer a version for consumers,” he said. Outside Ricoh, viewers seeing the design have used words like “wacky” and “curious” but are nonetheless impressed with its abilities.

The official Android blog carried the announcement last week in a posting by Android product manager, Benjamin Poiesz. The service will enable Android users to enjoy the same protective features that iPhone users enjoy with Apple’s Find my iPhone and that assorted third-party services offer those who have Android smartphones. Citation: Google’s ADM phone finder coming this month (2013, August 5) retrieved 18 August 2019 from https://phys.org/news/2013-08-google-adm-finder-month.html Lookout for Android, for example, has been a popular option thus far. The Lookout service carries a Lock It Down feature, where, If your device is in the wrong place at the wrong time, you remotely lock it to block access to your personal data. You can post a custom message to get it back, and there is the Wipe It Clean option to wipe data off the device if the user thinks the device is gone for good. You will not find any shortage of ‘Find My Phone’ services available. As for Apple, the Find my iPhone was announced back in 2010 as a software app to help pinpoint the exact location of an iOS device.Basically, the ADM phone finder covers all possible scenarios, for times when you accidentally drop your phone into a bag, or park it somewhere in the room where you cannot remember and need to hear it ring to locate the sound. What is nice about Android Device Manager is that even if your phone was in Silent mode the ADM will ring your phone at maximum volume. The second scenario is when you have forgotten your phone at some more remote location. The service will let you check its whereabouts on a map, If both scenarios don’t fit, and the phone is stolen, you have the option to wipe everything off the phone, erasing all data. Android Device Manager will be downloadable. Google says that you will need to be signed in to your Google account to use it. Several Android watching sites over the weekend, meanwhile, reported that the first stage of the ADM is being pushed out to a few users even though the service is not yet live. These users reported that the service was rolled out to their devices already. While it has taken Google some time to come out with its own find-phone solution, it can never be too late. Mobile security company Lookout viewed data last year and estimated that lost phones, if unrecovered, could cost U.S. consumers billions, They said at the time that “Losing your phone is more than just a hassle – it’s expensive. If everyone who misplaced their phone didn’t ever recover it, we estimate lost phones could cost U.S. consumers more than $30 billion in 2012.” Coffee shops, offices, bars and restaurants top the list as the most common venues to lose a phone in the U.S. The top U.S. city for lost phones is Philadelphia, and the most likely venue for losing a phone is a coffee shop. In London, they said, the top venue to lose a phone was a pub.last_img read more

Researchers test social contagion in laboratory setting

first_imgJudgment propagation down the chain. Observed intensity of social influence averaged over 20 experimental chains. The color coding indicates the influence of the originator’s judgment on the final estimates of all other individuals in the chain, as a function of their social distance from the originator (x axis) and the number of the round (y axis). Individuals located one degree of separation from the originator (i.e., social distance = 1) rapidly adopted the originator’s judgments (social influence approached 1 as early as round 2). Individuals located two degrees of separation from the originator were influenced by the originator after about 4 rounds of interaction. Participants located at a social distance greater than 3 were rarely influenced by the originator. Credit: arXiv:1704.01381 [physics.soc-ph] More information: Mehdi Moussaïd et al. Reach and speed of judgment propagation in the laboratory, Proceedings of the National Academy of Sciences (2017). DOI: 10.1073/pnas.1611998114 , On Arxiv: https://arxiv.org/abs/1704.01381AbstractIn recent years, a large body of research has demonstrated that judgments and behaviors can propagate from person to person. Phenomena as diverse as political mobilization, health practices, altruism, and emotional states exhibit similar dynamics of social contagion. The precise mechanisms of judgment propagation are not well understood, however, because it is difficult to control for confounding factors such as homophily or dynamic network structures. We introduce an experimental design that renders possible the stringent study of judgment propagation. In this design, experimental chains of individuals can revise their initial judgment in a visual perception task after observing a predecessor’s judgment. The positioning of a very good performer at the top of a chain created a performance gap, which triggered waves of judgment propagation down the chain. We evaluated the dynamics of judgment propagation experimentally. Despite strong social influence within pairs of individuals, the reach of judgment propagation across a chain rarely exceeded a social distance of three to four degrees of separation. Furthermore, computer simulations showed that the speed of judgment propagation decayed exponentially with the social distance from the source. We show that information distortion and the overweighting of other people’s errors are two individual-level mechanisms hindering judgment propagation at the scale of the chain. Our results contribute to the understanding of social-contagion processes, and our experimental method offers numerous new opportunities to study judgment propagation in the laboratory. It’s the thought that counts: The neuro-anatomical basis of forgiveness revealed (Phys.org)—Social contagion describes the propagation of beliefs, evaluations and attitudes through a network of people. It’s well understood that political beliefs, emotional attitudes and opinions are contagious within a network, but the precise mechanisms and dynamics are not well understood for two reasons: the complexity of network structures, and the behavioral processes that operate within the network. Explore further According to the three-degrees-of-influence hypothesis, judgement propagation is limited to a social distance of about three people—that is, an evaluative judgement typically will not spread beyond three degrees. Additionally, computer simulations demonstrate that the speed of judgement propagation decays exponentially with social distance from the source of the judgement. Researchers in Germany recently explored the mechanisms of evaluative judgement propagation through a social network. To determine the factors that influence or inhibit the transmission of a judgement, they designed a pair of experiments, and have reported their results in the Proceedings of the National Academy of Sciences.In the first experiment, they designed a visual perception task with three levels of difficulty, in which Subject A’s judgement and performance were repeatedly evaluated by Subject B. The researchers were interested in how repeated interactions between the subjects contributed to the contagion of a judgement.In the second experiment, they examined the collective dynamics of subjects with unidirectional chains of communication that extended to subjects C, D, E and F. All six participants repeatedly interacted with their predecessor, which allowed the researchers to gather data about reputation formation within a network and its resulting effect on the propagation of judgements.In accordance with the three-degrees hypothesis, the researchers found that judgements rarely propagated beyond three individuals; although they could spread farther, the time necessary to do so increased exponentially. Propagation over distances beyond three or four individuals required a consistently more accurate originator, absolutely error-free observation of others’ performance, and a network structure that remained static over several hundred interactions. These conditions are, needless to say, not easily replicated in the real world.The study found factors that impeded the propagation of judgements. Judgements become progressively more distorted over successive transmissions, even when individuals were able to observe the judgement and performance of another person. Judgements became less accurate, and thus less influential, the further they propagated from the source. Secondly, overweighting other people’s errors inhibited propagation. This is a common psychological phenomenon called “egocentric discounting,” well-known in literature. The problem arises because each performative error must be compensated with several good performances in order to restore reputation; this slows the transmission of judgement to the next subject. And for each step in the chain, the process repeats, leading to an exponential decay in transmission speed.The researchers suggest that further study could explore whether multiple sources of influence found in more complex networks could convey different judgements, thus contributing “noise” and impairing propagation; it is also possible that clustered networks with redundant ties could produce converging judgements along different pathways, providing social reinforcement to propagating judgements.

Keep it short silly

first_imgGet ready for a 10 minute dose of non-stop fun, as the theatre festival ‘Short and Sweet’ returns to the Capital this winter.  Delhi will be witnessing the third edition of world’s largest 10-minute theatre festival, which takes place in six countries. The festival started in Australia in 2003. Explaining the concept Short and Sweet, festival director Deepak Dhamija says: ‘This is the only platform where different theatre groups come together and perform plays. It is a unique concept to stage 10 minute plays because even in this time limit, it gives you the freedom to experiment. Various new forms of theatre will be explored during this festival which include clown theatre, Dastangoi and others.’ Also Read – ‘Playing Jojo was emotionally exhausting’The number of groups which are participating this year has gone up by 50 per cent. This year, around 40 groups and 100 participants will participate in the Delhi edition which will have nine shows spread over four weekends across four different venues. Theatre stalwarts like Sohaila Kapoor, Feisal Alkazi, Kuljeet Singh and Arvind Gaur will be directing pieces along with many others.’Our group will be performing the play Khol Do written by Saadat Hassan Manto, which is set in the Indo-Pak partition era. It was quite a challenge to encapsulate this play in 10 minutes especially with this subject, but we have tried our best. Thirty five actors form Asmita will be acting in this play,’ said Gaur.  Another theatre group participating is Dastangoi. Group founder-director Mahmood Farooqui has directed the play Also Read – Leslie doing new comedy special with NetflixDastan-e-mobile written by Ankit Chadha. ‘This is a Dastangoi presentation is on the usage of mobile phones and the problems and issues that a mobile consumer faces. Through this we have made an effort to explore the issues related to the mobile industry in India and how the consumer is exposed to problems in this system. We have also tried to probe the nexus between the carrier and operators and handset makers. It was quite a challenge to do it in 10 minutes but I thought it could be an experiment,’ said Chadha. Well, the results will be out soon.DETAILAt: India Habitat Centre, Kamani Auditorium, LTG Auditorium and Epicentre (Gurgaon)When: 22 November to 14 December Timings: 7.30 pmlast_img read more

Theatre festival by children for children

Various art forms are so rare and exquisite it has become the need of the hour that they be brought back into the limelight and be given due attention they so right fully deserve,’ Ratan Thiyam, National school of Drama, Chairperson said. Also Read – ‘Playing Jojo was emotionally exhausting’NSD plans to introduce drama therapy to help physically and mentally challenged children. The therapy, organisers say, will help them regain their confidence and will give them a platform to perform.’Theatre education helps a child to become more expressive and leads to overall personality development. This also makes them sensitive towards people and the society too. We are trying to work taking theatre in education to all states in the country,’ said Waman Kendre, Director, NSD.’Bal Sangam should be able to get an international platform and there should be a proper training program for teacher’s training in the field of theatre. This will help to bring more and more people to theatre,’ he said.The festival will include a street performance and traditional folk theatre performance groups.WHEN: 14 November onwards WHERE: National School of Dramalast_img read more
