The Core i5-750, Core i7-860 and Core i7-870, were launched by some of the leading manufactures that included Asustek Computer, Gigabyte Technology, Micro-Star International (MSI), Elitegroup Computer Systems and Foxconn Technology.To give you an idea of pricing, GenuinePC of Taipei, showed a desktop system with an Intel Core i7-860 2.8GHz quad core microprocessor, 500GB hard disk drive, 4GB of DDR3 DRAM, Nvidia 9800GT graphics card and a Blu-ray Disc combo drive with Microsoft Windows Vista Home Premium, selling for 1,219 US dollars.New software and operating systems are being re-engineered to take advantage of the multi-core and multi-threading capabilities. Both Apple’s Snow Leopard (Mac OS X 10.6) and Microsoft’s Windows 7 are both optimized for the Core i5 and i7.Turbo mode, in the Core i5 and i7 can significantly boost the chips overall processing speed for short burst of intensive activity. This process directs one or more of the cores and diverts their processing capability to a single engine. Thereby a chip rated for 2.8GHz can increase to 3.2GHz on demand without stressing the chip or running the risk of overheating.Via: Digital Life© 2009 This document is subject to copyright.

Glass electrodes used in nanoscale pump

first_img More information: Sanghyun Lee et al., Liquid glass electrodes for nanofluidics, Nature Nanotechnology, Published online: 16 May 2010 | doi:10.1038/nnano.2010.81 Storing a Lightning Bolt in Glass for Portable Power ( — A team of engineers from the U.S. and South Korea has developed what is believed to be the smallest man-made pump ever built, powered by a glass electrode. The pump is about the same size as a red blood corpuscle. © 2010 Explore further Citation: Glass electrodes used in nanoscale pump (2010, May 17) retrieved 18 August 2019 from SEM showing surface roughness of the fs-laser machined nanochannel. Image credit: Nature Nanotechnology, doi:10.1038/nnano.2010.81. While glass does not normally conduct electricity, the team discovered a few years ago that at the nanoscale glass can conduct electricity without breaking. They have now used the property to solve a problem inherent in nanodevices, which is the difficulty of integrating wires into them to provide the required electrical current.The engineers involved in the research were Sanghyun Lee from South Korea’s Pohang University of Science and Technology, and Alan Hunt and Ran An from the University of Michigan in Ann Arbor in the U.S. They machined nanochannels inside a glass substrate (a microscope cover slip) using a new laser technique (called “femtosecond-laser nanomachining”), leaving a thin glass wall at the tip of each channel that can change properties reversibly from an insulator to a conductor in the presence of high electric fields. This phenomenon is called “dialectric breakdown,” and usually results in overheating and damage, but at the nanoscale there is no damage to the glass.When the channel is filled with an electrically conducting solution it effectively becomes a tiny liquid wire, with the glass wall at the end acting as an electrode. Hunt described the thickness of the glass wall by saying that “if Alice ate a mushroom in Wonderland and shrank to the size of a gnat, the thread in her dress would be about as thick as the conductive glass wall in the electrode.”The team demonstrated the glass electrodes by using them to power a microscopic pump consisting of an assembly of three 0.6-micrometer-wide glass electrodes. Each electrode consists of two channels positioned end to end with the glass wall between them. The wall would normally prevent the electrolyte and electric current from passing through, but at the nanoscale applying an electric potential of only 10 volts was enough to transform the insulating glass into a conducting electrode. The heat generated by dielectric breakdown was dissipated so quickly at this scale that there was no damage to the glass.The pump works by electroosmosis, in which electricity pushes the fluids from one end of the pump to the other. The heart of the pump measures only four micrometers across, and the pump is capable of controlling a flow rate of one femtoliter (10-15 liters) per second. It could be used for applications such as delivering drugs to an individual cell or for taking fluid samples from single cells. The glass electrodes could also be integrated into other nanoscale devices.The results of the research are published online in Nature Nanotechnology. This document is subject to copyright.

EEG helmet is being developed as interrogation device

first_imgTonic firing pattern of single neuron showing rhythmic spiking activity. Image: Wikipedia. ( — Veritas Scientific is working on an EEG helmet that carries a slideshow of images that could, they hope, reliably identify an enemy. The device is shaped like a motorcycle-helmet with metal brush sensors that will read brain activity as images flash quickly across the inside of the visor. Electroencephalography (EEG) is the science of measuring brainwave patterns produced by the brain in response to internal or external stimuli. Familiar images prompt spikes of electrical brain activity that indicate recognition, say scientists.

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. Fitted tightly to the head without being painful, the helmet is designed to be soundproofed against the outside world. The visor’s images are displayed centimeters from the eyes. The metal brush sensors, still in development, are being designed to go easily through hair and conduct brain signals without the conductive gel used in hospitals. This would be an advantage as traditionally attempts by researchers to use EEG head gear on subjects have drawn uneasy participant experience, as electrodes were glued, pasted or taped to the participant’s scalp, Many researchers in the EEG field seek to liberate EEG testing activity out of the lab and into more mobile environments.Interestingly, the company places its helmet work in the realm of “interrogation technology.” Veritas Scientific sees its device of use to the U.S. military to help them pick friend from enemy among people they capture. The technology is also suggested as useful for law enforcement. EEG experiments on mock terrorism plots have been conducted in laboratories; Veritas wants to put its helmets on real suspected terrorists. The company’s CEO, Eric Elbot, has described his work as pioneering in the use of brainwaves for interrogation deception detection for the intelligence community. Elbot hopes to have a prototype ready for the U.S. military’s war games months from now and is pursuing a military contract. Veritas draws on the work of J. Peter Rosenfeld, a professor of psychology and neuroscience at Northwestern University. Rosenfeld develops EEG tests that weed out lies. In a past experiment using P300 brain-wave testing in a mock terrorism scenario in which make-believe persons of interest were planning a crime, Northwestern University researchers were able to detect guilty knowledge with 100 percent accuracy with no false positives. “Even when the researchers had no advance details about mock terrorism plans, the technology was still accurate in identifying ten out of 12 terrorists and 20 out of 30 crime-related details,” Rosenfeld said. “The test was 83 percent accurate in predicting concealed knowledge, suggesting that our complex protocol could identify future terrorist activity.” With electrodes attached to their scalps, connected to an EEG machine, they looked at a computer display monitor that presented names of stimuli. The names of Boston, Houston, New York, Chicago and Phoenix were shuffled and presented at random. The city that study participants chose for the major terrorist attack evoked the largest “P300” brainwave responses. As for worries about the use of an “interrogation technology” being wrong when a person’s life is as stake, the company notes that its helmet is still being tested. In a report in IEEE Spectrum, Veritas Scientific emphasized its devotion to “extremely high” accuracy.Also, said a Veritas Scientific source, the device is intended to be one of other factors used and decisions would be left to humans, not machines. Peter Lauro, head of Veritas’s neuroscience h, said that the company continues to examine the right combination of ERPs (event-related potentials), questions, and image patterns for a reliable deception test. As work continues, they plan to add functional near-infrared imaging (fNIRs) to the helmet. This is a brain imaging technology that measures blood flow. © 2012 Reading terrorists minds about imminent attack: P300 brain waves correlated to guilty knowledgelast_img read more

Opera plans transition to WebKit engine

first_img Citation: Opera plans transition to WebKit engine (2013, February 13) retrieved 18 August 2019 from (—Opera will ditch its web browser rendering engine called Presto and instead will switch over to WebKit in a planned 2013 phase-out. The decision was announced this week. WebKit is the rendering engine used in Apple’s Safari and Google’s Chrome. According to the announcement, “Opera will make a gradual transition to the WebKit engine, as well as Chromium, for most of its upcoming versions of browsers for smartphones and computers.” Writing in the Opera developer blog, Bruce Lawson, Web evangelist for Opera, said consumers would see the difference. “Consumers will initially notice better site compatibility, especially with mobile-facing sites, many of which have only been tested in WebKit browsers.” Opera will preview its first Chromium-based smartphone browser for Android later this month at the Mobile World Congress in Barcelona. Why switch now? In its announcement, Opera said its goal was “to provide a leading browser on Android and iOS.” Android and iOS both use WebKit-powered browsers. Opera’s CTO, Håkon Wium Lie, said that WebKit “supports the standards we care about, and it has the performance we need,” He said, “It makes more sense to have our experts working with the open source communities to further improve WebKit and Chromium, rather than developing our own rendering engine further.” Also elaborating on the decision, Lawson went back to 1995, when Opera rolled its own rendering engine, competing against Internet Explorer and Netscape, and hoping to drive web standards forward. He said that goal was a specification to enhance web interoperability. “The WebKit project now has the kind of standards support that we could only dream of when our work began.”Reactions outside Opera did not indicate a unanimous thumbs-up. Several blogs suggested the move will make it easier for developers in terms of testing. Mozilla developer Robert O’Callahan expressed disappointment with Opera’s decision, however, saying that Google and Apple’s WebKit may end up being a good one for the company, but unlikely to be good for the web at large. “More and more developers don’t write websites or web apps based on standards but based on what works in WebKit.”Opera, meanwhile, said that it has already made its first contribution to WebKit, a set of patches to make WebKit’s handling of CSS columns as capable as Presto’s. “Opera will contribute to the WebKit and Chromium projects, and we have already submitted our first set of patches: to improve multi-column layout,” according to the company.Opera will use WebKit as its rendering engine and also V8 as its JavaScript engine. According to Opera, 300 million people use Opera web browsers for computers, mobile phones, TVs and other connected devices.

Router compromise rogue remote control Easy says ISE

first_img( —Router hacking is joining the ranks of computer security headaches, where the wireless router becomes the key target for those seeking to trespass into someone else’s network. The remote attacker can take full control of the router’s settings or just bypass authentication and takes control. The attacker is free to modify traffic as it enters and leaves the network. Wrote Michael Mimoso in Threatpost, from Kasperksy Lab, “Hackers love to attack Java. Why? Well, not only because it is full of holes, but because it’s everywhere, embedded on endpoints, Web browsers, mobile devices and more. The same goes for attacking wireless routers; they’re buggy and they’re everywhere.” Citation: Router compromise, rogue remote control? Easy, says ISE (2013, April 21) retrieved 18 August 2019 from Belkin N900 router More information: … oho_router_hacks.jsp Netgear Launches A New Family Of Wireless-N Routers Earlier this week, that turned out to be more than a quip as, beyond Kasperksy Lab, other researchers exposed critical security vulnerabilities in small office and home office (SOHO) routers and wireless access points. The research was from Baltimore, Maryland-based Independent Security Evaluators. Their key findings: All of the 13 routers they looked at can be taken over from the local network (four never requiring an active management session) and 11 of the 13 can be taken over from the WAN (two never requiring an active management session). Actually, there is a another important takeaway from their research: The wireless router hacking vulnerabilities they examined do not take a pile of expertise. “Our research indicates that a moderately skilled adversary with LAN or WLAN access can exploit all thirteen routers,” they said. But while attackers may not need esoteric skills to break into routers, the ISE experts said the average end user can do little to fully mitigate such attacks.”Successful mitigation often requires a level of sophistication and skill beyond that of the average user (and beyond that of the most likely victims).”ISE’s team said the vendors of these networking devices should be in the front of the line for mitigation actions. Actions they can take include preparing firmware upgrades that address the issues, instructing their registered users how to upgrade device firmware; be timely in the issue and customer notification of patches; and design a method for automatic firmware updates with the opportunity for users to opt out; and perform regular security audits to ensure devices are as hardened as possible. ISE has also announced its future plans toward focusing on SOHO routers. All signs are that they will stay on the case. “Six months after releasing the advisories for the 13 routers, ISE will upgrade the firmware on all 13 routers and perform a reassessment to determine what—if any—impact deeper scrutiny from the security community has brought to the SOHO router industry.” According to ISE, its next study may include more than the 13 routers seen so far.This research was conducted by Jacob Holcomb and directed by Stephen Bono and Sam Small. Jacob Thompson, Kedy Liu, Jad Khalil, and Vincent Faires also contributed. Explore further © 2013 This document is subject to copyright.

New CCCCC pentadentate chelates with properties for use in photothermal therapy

first_imgIn order to get this pentadentate compound into the body, Zhu, et al. loaded the pentadentate on PEG micelle nanoparticles. They found that when interacted with SCC7 cells, a squamous cell carcinoma line, the tumor volume and cell viability decreased substantially compared to controls. Since in vitro testing worked so well, Zhu, et al. then wanted to see how the pentadentate nanoparticles worked in vivo.Studies with SCC7 tumor-bearing mice showed that after fourteen days, the control group had tumors that were larger (up to twelve times larger) than at the beginning of the experiment. The group with the nanoparticles, however, showed a significant decrease in tumor size and comparable efficacy to nanotubes and nanoporphyrins. This work demonstrates a new CCCCC pentadentate structure in which the five-carbon coordination center is co-planar with the metal. These new compounds provide an example of a rare type of aromaticity and have properties that make them excellent candidates for photothermal therapy. Finally, Zhu, et al. tested whether theses pentadentate compounds could be used for photothermal therapy. For PTT, often IR or near-IR is used to apply heat to cancer cells in an effort to destroy the cells. The various pentadentate compounds were first tested to determine the relationship between the concentration of the pentadentate compound and solution temperature. The compound with benzene substituents showed the most promising temperature changes. © 2016 In a study recently published in Science Advances, several researchers from Xiamen University in China report the synthesis and characterization of a pentadentate, five-carbon, chelating molecule. This planar molecule coordinates osmium and is amenable to several substituents. Furthermore, its properties make it a good candidate for photothermal therapy.The current study builds on work by this group in which they found that the ligand’s Möbius aromaticity plays a key role in stabilizing the metal center. Möbius aromaticity stems from molecular orbital theory in which an aromatic ring’s pi-donating atomic orbitals rotate around the ring like a Mobius strip. This study reports the synthesis of a ligand with planar 12-center 12-electron dπ-pπ pi-conjugation, the largest planar Möbius aromatic system reported. It is comprised of two fused five-member rings, a six-member ring, and a three-member, non-aromatic ring. Structurally, the five carbon donor atoms are in the same plane (equatorial) while the two phosphorous atoms are in the axial plane. The osmium metal is almost co-planar with the carbon atoms. The C-Os bond lengths indicate delocalized bonds. As reported by the authors of the study, this structure represents the highest coordination number for a metal atom coordinated to carbon donor atoms in planar geometry. The synthesis of these planar pentadentate compounds was fairly straight-forward involving a ring expansion with alkynes or allenes with various substituents. The first product, resulting in phenyl substituents on the six-membered ring and the three-member ring was made with 3-ethynylthiophene and silver borohydride at room temperature. This product, as well as the ones with cyclohexane, cyclopropane, and thiophene substituents was characterized with NMR, high-resolution mass spectrometry, and elemental analysis, all of which confirmed a pentagonal bipyramidal structure and delocalized Os-C bonds.UV-Vis studies and near-IR showed that the absorption spectra changed based on different substituent groups (See figure above). This indicates that the pentadentate compound’s photophysical properties change based on structural differences. This could have implications for tuning these compounds for practical uses. (—Macrocyclic and chelating molecules are important in physiological processes and pharmaceuticals. Hemoglobin, for example, is a chelating molecule in which iron is coordinated to donor atoms in a porphyrin ring. Often the donor atoms are some combination of nitrogen, oxygen, phosphorous, and sulfur. For example, nitrogen serves as the donor atoms in hemoglobin. Sometimes carbon acts as a donor atom, but it is usually as a heterocycle with one of these other atoms.

CCCCC pentadentate chelates with planar Mo bius aromaticity and unique properties, Science Advances (2016). DOI: 10.1126/sciadv.1601031AbstractThe coordinating atoms in polydentate chelates are primarily heteroatoms. We present the first examples of pentadentate chelates with all binding atoms of the chelating agent being carbon atoms, denoted as CCCCC chelates. Having up to five metal-carbon bonds in the equatorial plane has not been previously observed in transition metal chemistry. Density functional theory calculations showed that the planar metallacycle has extended Craig-Möbius aromaticity arising from 12-center–12-electron dπ-pπ π-conjugation. These planar chelates have broad absorption in the ultraviolet-visible–near-infrared region and, thus, notable photothermal performance upon irradiation by an 808-nm laser, indicating that these chelates have potential applications in photothermal therapy. The combination of facile synthesis, high stability, and broad absorption of these complexes could make the polydentate carbon chain a novel building block in coordination chemistry.

Study suggests humans are now producing more chemical waste than can be

first_img Citation: Study suggests humans are now producing more chemical waste than can be tested (2019, February 27) retrieved 18 August 2019 from A team of experts convened by Professor Sir Charles Godfray of the Oxford Martin School has found evidence that suggests humans are dumping more chemical waste into the environment than can be tested for its impact. In their paper published in Proceedings of the Royal Society B, the group describes their review of recent research surrounding the amounts and types of chemicals being dumped into ecosystems and what they found. © 2019 Science X Network Freshwater male fish exposed to chemicals in water becoming more feminine For many people, pollutants dumped into ecosystems evokes images of pipes pumping waste into rivers from large industrial complexes. But the actual picture is far more complex. Agricultural runoff is a major pollution problem, as are landfills leaking chemicals into water sources. There is also the growing problem of chemicals being washed down the drain in kitchen sinks and, perhaps worse, down bathroom shower drains and toilets. Humans produce thousands of chemicals and use them in wildly different ways—from chemicals to make our lawns grow to chemicals in birth control pills that show up in our urine. In this new effort, the researchers claim that the world now collectively dumps more chemicals into the natural environment than can be tested—and because of that, we really do not know what damage it may be causing.In their review, the researchers focused mainly on endocrine disrupting chemicals, which include PCBs from plastics and drugs such as antidepressants and birth control pills. Such chemicals are known to disrupt reproduction in marine animals. As one example, they note that a pod of killer whales living off the coast of Scotland has not produced a calf in at least 25 years—one female washed ashore was tested, and researchers found levels of PCBs 100 times higher than the dose considered toxic.What most concerns the researchers is the rate at which new chemicals are being introduced and used and which eventually wind up in natural ecosystems, which is so high that there is no way to test their impact. We may be flushing chemicals into the ocean right now that could potentially kill off most if not all marine animals, and not even know it. They conclude by suggesting that more work is required to investigate the problem and to look for ways to address it. Explore furthercenter_img More information: H. Charles J. Godfray et al.

Trump Says Russia Should Be Allowed Into G7

first_img by NPR News Sasha Ingber 8.21.19 9:35am President Trump says Russia should be allowed to rejoin the Group of Seven industrial nations, and Russia’s foreign ministry has welcomed his remarks.Speaking with reporters in the Oval Office on Tuesday, before his scheduled trip to France for the G-7 summit, Trump encouraged Moscow’s return to the elite group.”I think it’s much more appropriate to have Russia in,” he said. “It should be the G-8 because a lot of the things we talk about have to do with Russia.”Trump characterized Russia’s ousting to his predecessor’s humiliation on the world stage, offering little to substantiate his claim.”President Obama didn’t want Russia in because he got outsmarted,” Trump said.Russia was excluded from the G-7 in 2014 after its troops invaded Ukraine and President Vladimir Putin annexed Crimea. Western leaders condemned the actions as a “clear violation of international law” and sought to penalize the Russian government.On Wednesday, Russian Foreign Ministry spokeswoman Maria Zakharova appeared to embrace the door Trump opened, according to Russia’s news agency Tass. “Initiatives need to be outlined and handed over to Russia for consideration,” Zakharova said. “At the moment, it is hard to understand what it is all about, so if the G7 wants to position itself as a serious platform, the discussion should be moved from the media field to the expert level.”Trump’s appeal on Tuesday did not mark the first time that he called on the group – France, Germany, Britain, Canada, Italy and Japan – to bring Russia back into the fold. In June 2018, Trump told reporters that “we should have Russia at the negotiating table.”His remarks on Tuesday did not include a mention of Crimea or any conditions for Russia to be reinstated.French President Emmanuel Macron has continuously called on Moscow to help end the conflict in Ukraine before Russia can return to the group.The summit started in 1975 when leaders of six industrial countries met at the Chateau de Rambouillet, an hour outside of Paris, to discuss economic crisis. Canada joined the next year. And in 1991, the G-7 invited Mikhail Gorbachev, the last leader of the Soviet Union, to talks in London. Russia was formally admitted to the group in 1998.Copyright 2019 NPR. To see more, visit NPR. Trump Says Russia Should Be Allowed Into G-7, Moscow Wants… Alex Wonglast_img read more

Dorian Will Hit Florida As A Major Hurricane

first_img by NPR News Bill Chappell 8.28.19 12:06pm Updated at 11:30 a.m. ETTropical Storm Dorian is poised to become a hurricane as it bears down on Puerto Rico and the Virgin Islands, bringing heavy rain and sustained winds up to 70 mph. Forecasters are now warning the storm will strengthen into a dangerous Category 3 hurricane as it nears the U.S. mainland.Puerto Rico, Vieques and the U.S. Virgin Islands are now under alert, with hurricane conditions expected as the storm passes through that area later Wednesday. Dorian is currently some 25 miles southeast of St. Croix, the National Hurricane Center says in its 11 a.m. ET update on the storm.Dorian will likely strengthen somewhat as it approaches Puerto Rico. And while it could lose some intensity by passing over that land mass, the storm is then expected to gain power. Within four days, its winds could top 115 mph, the National Hurricane Center says.”All indications are that by this Labor Day weekend, a powerful hurricane will be near the Florida or southeastern coast of the United States,” the NHC says.The center’s current predictions show Dorian hitting Florida’s coast late Sunday or early Monday. It’s expected to become a major hurricane (Category 3 and above) as it moves north of the Bahamas.While the center initially predicted the storm would weaken somewhat into a Category 2 — with winds of 100 mph — as it drew close to Florida’s coast, it quickly issued a correction to its 11 a.m. update, clarifying that the storm will likely arrive as a major hurricane.As meteorologist Philip Klotzbach notes, “The average date for the 1st Atlantic major hurricane is September 3.”The center’s forecasts currently predict the storm will make landfall near an area that’s level with Orlando. But that potential location is subject to change drastically, as the storm develops.Forecasters are warning of the potential for life-threatening flash floods in the storm’s path. Southern and eastern portions of Puerto Rico and the Virgin Islands could see 4-6 inches of rainfall, with 10 inches possible in isolated areas. When the storm reaches Florida, it’s expected to drop 4-8 inches of rain, with 10 inches in some spots.Noting the potential landfall estimate of 8 a.m. ET Monday, Graham NHC Director Ken Graham cautioned, “the impacts could come a lot earlier than that,” saying intense rain, tropical-storm winds and a storm surge could begin to affect the coast far ahead of the storm’s center.Acknowledging that considerable uncertainty remains over the path Dorian will take as it nears the southeastern U.S., Graham also said anyone on the coast from Florida up through Georgia and South Carolina should watch for potential hazards.Citing data collected from Air Force Hurricane Hunters and other sources, the NHC says, “Dorian remains a compact and asymmetric tropical storm.” But that could change; the center says some projection models show Dorian “increasing in size by the time it nears the southeast U.S.”While Dorian’s wind speeds have only grown by 10 mph since Monday, it’s now projecting tropical storm-force winds outward up to 80 miles from the center — up from 45 miles on Monday and Tuesday.By 9:30 a.m. ET, Dorian’s outer bands were beginning to move over eastern Puerto Rico, according to the National Weather Service office in San Juan. To prepare for rough conditions at sea, the Coast Guard captain in San Juan set “Port Condition ZULU” Wednesday for all ports in the U.S. Virgin Islands and Puerto Rico, shutting down all commercial traffic until the storm has passed and the facilities have been assessed.Late Tuesday, President Trump declared an emergency in the commonwealth of Puerto Rico, ordering the Federal Emergency Management Agency to provide “equipment and resources necessary to alleviate the impacts of the emergency.”Puerto Rico Gov. Wanda Vázquez Garced thanked Trump for approving the declaration, saying it would “allow federal aid to arrive more quickly” after the tropical storm passes.As it announced an increased threat of hurricane conditions on Florida’s east coast, the hurricane center noted early Wednesday that its forecasts are “on the lower end of the guidance envelope” — meaning it could raise more dire warnings as the storm continues to develop.The fifth named storm of the 2019 Atlantic season formed late Tuesday, as Tropical Storm Erin’s winds reached 40 mph. The storm is out in the Atlantic, several hundred miles southeast of Cape Hatteras, N.C. The storm was downgraded to a tropical depression on Wednesday. Erin is expected to remain on a north-northeastern track, likely arriving at Canada’s coast late this week.Copyright 2019 NPR. To see more, visit NPR.

At its core is a need for closeness and intimacy. Women also have physical needs. When there is an emotional or physical problem, they can have sexual problems. Lack of interest in sex can also be triggered by family problems, illness or death, financial or job worries, in-law problems, childcare responsibilities, managing a career and children, previous or current physical and/or emotional abuse, past history of sexual abuse, fatigue and depression. Sometimes for women, the inability to become physically aroused during sexual activity often involves insufficient vaginal lubrication. The biggest problem is that most men get sex education from their friends, TV and porn movies. In normal lives, sexuality is far different from how it is portrayed in porn and men fail to understand this! Women are much more interested in romance and relationship than in casual intercourse. Psychological counselling can play an important part, as can coaching in sexual foreplay and stimulation techniques. Have a love or life query you cannot find an answer to?

Humorous ads may hurt brand name

first_imgAdvertisements that make people laugh are not always in the best interest of brands and can prove to be harmful, warns a study that has cautioned ad makers.The findings showed that people find humour in “benign violations” – things that somehow threatens their sense of well-being, personal identity or beliefs – only if they are harmless or inconsequential. “Different ads can be equally humorous to consumers but have very different effects on brand attitudes, depending on the type of humour used,” said lead author Caleb Warren, Assistant Professor at the University of Arizona in the US. Also Read – Add new books to your shelfPeople’s attitudes toward brands are important, as they ultimately influence purchasing decisions. Thus, advertisers should stay away from ads that feature highly inappropriate humour, humour with a specific target or “butt of the joke,” and humour that prompts avoidance by eliciting feelings such as disgust in addition to laughter.”When there’s a more severe violation, even though people find it funny, they like the brand or the retailer selling it less,” Warren added. Also Read – Over 2 hours screen time daily will make your kids impulsiveIn one of the experiments conducted, the researchers looked at the effects of humour targeting a single person or group of people. They created two versions of an insurance company ad showing a car crashed into the side of a house. One had the caption “Everyone drives like an idiot sometimes,” while the other said “Everyone drives like a woman,…” A control ad merely showed a truck with a smashed front end and the words “Accidents happen sometimes.” The “inclusive” ad, which, was shown only to male participants, mocked bad drivers in general, improved brand attitudes relative to the control ad, while the “exclusive” ad, mocking only women drivers, did not. Testing audience before launching an ad is a good idea to gauge whether something will be perceived as funny, the researchers suggested. The study was published in the Journal of Marketing Behaviour.last_img read more
