Why Teenagers Are So Impulsive

first_imgSAN DIEGO, CALIFORNIA—Why do teens—especially adolescent males—commit crimes more frequently than adults? One explanation may be that as a group, teenagers react more impulsively to threatening situations than do children or adults, likely because their brains have to work harder to rein in their behavior, a research team reported here yesterday at the Society for Neuroscience meeting.Whether it’s driving too fast on a slick road or experimenting with drugs, teenagers have a reputation for courting danger that is often attributed to immaturity or poor decision-making. If immaturity or lack of judgment were the only problem, however, one would expect that children, whose brains are at an even earlier stage of development, would have an equal or greater penchant for risk-taking, says Kristina Caudle, a neuroscientist at the Weill Cornell Medical College in New York City who led the study. But younger children tend to be more cautious than teenagers, suggesting that there is something unique about adolescent brain development that lures them to danger, she says.It’s hard to generalize about teenage impulsivity, because some adolescents clearly have more self-control than many adults, says principal investigator B. J. Casey, a neuroscientist. Still, a growing body of evidence suggests that, in general, teens specifically struggle to keep their cool in social situations, she says. Because many crimes committed during adolescence involve emotionally fraught social situations, such as conflict, Caudle and colleagues decided to test whether teens perform badly on a common impulsivity task when faced with social cues of threat. They recruited 83 people, ranging in age from 6 to 29, to perform a simple “Go/No-Go” task, in which they watched a series of faces making neutral or threatening facial expressions flicker past on a computer screen. Each time the participants saw a neutral face, they were instructed to hit a button. They were also told to hold back from pressing the button when they saw a threatening face. As the participants performed the task, the researchers monitored their brain activity with functional magnetic resonance imaging.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)On the whole, teenagers made about 15% more errors than adults and children when attempting to stop themselves from pressing the button when they saw the threatening facial expression, the team reports. Males performed worse than females, suggesting a sex difference that fits with the disproportionate number of crimes that male teens commit, Caudle says. Those adolescents who did manage to restrain themselves showed significantly higher activity in a brain region called the ventromedial prefrontal cortex (vmPFC), which is involved in top-down control of behavior. “You could think of it as the brake,” Caudle says. “It’s as if the teenage brain might need to work a little harder to hold that response back.” This could help explain why teenage criminals are less likely to be repeat offenders, the researchers say—as their brains develop into adulthood, it gets easier for them to rein in their behavior.”This work strongly suggests that the teenage brain is highly impulsive in the face of threat and points to unusual vmPFC activity as a possible biological underpinning,” says Jon Horvitz, a neurobiologist at the City College of New York. “It is an exciting finding.”last_img read more

Indian men beat Nigeria, clinch bronze in table tennis

first_imgShrugging off the disappointment of a 1-3 semifinal loss to England, Indian men’s team spanked Nigeria 3-0 in third place play-off to clinch the bronze in the Commonwealth Games’ table tennis competition in New Delhi on Saturday.It was an easy win for the Indians, who were off-colour in the final-four clash on Friday and had failed to match their opponents in every department of the game.On Saturday, Olympian Achanta Sharath Kamal gave the hosts a winning start, beating Akinade A Quadri 3-0 and then A Amalraj eased past Monday Merotohun with an identical scoreline at the Yamuna Sports Complex.In the third tie, Abishek Ravichandran lost the first set 14-16 to Seun Ajetunmobi, but soon found his touch and clinched three sets back to back (11-6, 11-8, 11-7) to ensure a podium finish for the home side.Although the paddlers were happy with their performance on Saturday, they continue to rue their defeat to the British side in the previous match.”Today we played good and did not give much chances to them. But I am feeling bad, because if we would have defeated England it would have been better,” Amalraj told after the match.”Yesterday they (England) were playing better and were also quite comfortable with Sharath,” he added.However, he was happy to win his first CWG medal, that also in front of the home support. “But the mood of the team members is fine. We have won the bronze and we are happy for that.”advertisementAbishek said, “It is the first CWG medal for me too. We got a good start in the match and after that it was not very tough to beat Nigeria. We also got good support from the crowd.”But it would have been more special had we overcome England,” he added.- With PTI inputslast_img read more

Quebec floods situation stabilizing but water levels slow to drop

first_imgMONTREAL – The situation in flood-stricken Quebec appeared to improve slightly on Friday as the provincial government reported a drop in water levels in some areas and downgraded a forecast for weekend rain.But water levels are still expected to rise in the central Quebec region of Mauricie and they remain high in some large lakes, Environment Minister David Heurtel told a news conference.He said the Mauricie region will likely get 20 to 25 millimetres of rain over the weekend instead of the 59 millimetres officials had feared earlier this week.“Our models nevertheless indicate an increase (in water levels) but not as large as expected,” he said.Premier Philippe Couillard said he was hoping the situation wouldn’t deteriorate over the weekend.“We will breathe a sigh of relief on Monday if we haven’t had massive rain and heavy overflow,” he said at the sidelines of an event in Montreal.“In the meantime, we’re crossing our fingers.”As of Friday evening, the province’s civil security department said 4,700 residences had been stuck by flooding and just under 3,900 people have been moved out of their homes in 175 communities.The city of Rigaud, west of Montreal, warned that citizens who refuse the town’s evacuation order could face fines of up to $5,000.Mayor Hans Gruenwald Jr. said about 19 people have refused to leave their homes and have been notified that they could face penalties.“They’re being told something by their community and they have to listen, and if they don’t there are consequences,” he told reporters.Public Security Minister Martin Coiteux said that compensation for flood victims will be reviewed and likely increased in some areas.He said municipalities that haven’t been affected by flooding would lend technical expertise, human resources and equipment to help with cleanup efforts.“We’re preparing the recovery phase that will start earlier in the western areas (of the province),” he said.As flood waters continued to recede in Montreal, fire Chief Bruno Lachance warned citizens of the dangers they could face when returning home.“There are still some risks in the homes, (such as) electrical risks, natural gas, structure,” he said, adding residents should contact the city for help with inspections.Lachance said that while the homes closest to the river were still flooded, others were gradually becoming available for homeowners to visit.One of those residents, Nick Cai, surveyed the damage as the military-built dike helped drain his street, which was “still a lake” one day earlier.His street — 5th Ave. N. in the Pierrefonds-Roxboro area — has been in the news because it was badly flooded and residents claim repeated requests for help were ignored.“I think from the beginning, for our street, it’s a kind of a tragedy — it shouldn’t have happened at all,” Cai said.On Friday, Cai waited for the green light for electricity to be turned on, surveying the mess that will require professionals to help clean up.“I think it’s huge — at least, my basement is finished,” Cai said.“Some houses, there’s water on the first level so they have to be torn down and rebuilt completely.”The Ontario government said Friday it has activated one of its disaster assistance programs and individuals and businesses may be eligible for aid in dealing with the effects of flooding.— with files from Morgan Lowrie and Sidhartha Banerjee in Montreal.last_img read more

I Will Not Use My Fathers Position to Obtain a Job

Rabat – Soumia Benkirane, the daughter of the current Head of Government, Abdelilah Benkirane, has reportedly made it clear she will not use her father’s post to obtain a job.In an interview with Al Arabia, Soumia Benkirane, who has a degree in Islamic studies, said that she refused to use her father’s position as the Moroccan head of government to get a job.“Some relatives and friends were wondering why I was not hired after my father was appointed the head of the government, saying that if they were in my father’s position, they would take care of their family and relatives before anything else,’’ said Soumia Benkirane. She goes on to add that it took them much time to understand that “Abdelilah Benkirane will hire no one illegally, neither his sons and daughters, nor his relatives.’’Soumia Benkirane said that she has decided to continue her studies and seek a higher degree in law in order to facilitate her integration in the labor market, rather than asking her father to use his power and get her a job.“Neither I nor my father will allow ourselves, one day, backsliding from any principle of the Justice and Development Party, particularly fighting corruption,’’ Soumia added. read more

Perdue says farmer aid package still a work in progress

WASHINGTON — Agriculture Secretary Sonny Perdue says his agency is still “in the throes of constructing” an aid package for farmers hurt by retaliatory tariffs, but he is not saying when it will be ready.Perdue says the Agriculture Department is reviewing feedback from producers about the strengths and weaknesses of last year’s relief package, valued at nearly $12 billion.Perdue says he believes this year’s assistance will be enough to offset losses caused by the tariffs. He also predicts the current trade battles with China will not cause long-term harm to U.S. farmers.Perdue, speaking from South Korea, has been tasked by President Donald Trump to assist farmers who have seen prices for their products fall because of tariffs imposed by China in response to tariffs that Trump initiated.Kevin Freking, The Associated Press read more

Sales were up 0.3 per cent in May following a 1.7 per cent surge in April. That had been the biggest sales increase in more than a year.The strong increase in inventory building in May could be evidence that businesses are growing more confident about the future. A decision to accelerate inventory stocking would help bolster overall economic growth.The May rise left inventories at the wholesale level at a seasonally adjusted $449.8 billion, 3.8 per cent below a year ago.Economists believe sales at both the wholesale and retail levels will rebound in coming months after a slowdown in the first quarter that was caused in part by unusually frigid weather. A pickup in consumer spending, which accounts for 70 per cent of economic activity, is expected to translate into stronger economic growth for the rest of the year.The government has already reported that retail sales accelerated solidly in May.The big inventory gain in May reflected larger stockpiles of autos and auto parts as well as furniture, lumber and computers.In the January-March quarter, the harsh weather and other factors sent the economy into reverse with the gross domestic product contracting at an annual rate of 0.2 per cent. But analysts are forecasting a strong pickup in the current growth to GDP growth of around 2.5 per cent.They expect growth will accelerate further in the second half of the year to a rate around 3 per cent. read more

UN agency spotlights climatesmart approach to galvanize rural renewal

“A shift to climate-smart agriculture will not only help shield farmers from the adverse effects of climate change and offer a way to reduce greenhouse gas emissions,” said Helena Semedo, Deputy Director-General of the UN Food and Agriculture Organization (FAO), stressing that it “can also improve farm yields and household incomes, leading to stronger, more resilient communities.” The newly released FAO success stories on climate-smart agriculture, underscores the urgency of combating climate change, the magnitude and scope of which has a universal and critical impact on agricultural systems. Therefore, safeguarding global food security needs galvanize rural communities’ resilience and adaptation.Rising temperatures and frequent weather extremes, according to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), will have direct and negative consequence on crops, livestock, forestry, fisheries and aquaculture productivity. Of great risk are those vulnerable and farming-dependent populations in the developing world.”We can no longer afford to separate the future of food security from that of natural resources, the environment and climate change – they are inextricably intertwined and our response must be as well,” Ms. Semedo warned. However, this alarming situation has spurred an opportunity to gain traction on climate-smart agriculture, which includes the following three broad objectives: to sustainably increase agricultural productivity and incomes; to adapt and build resilience to climate change; and to reduce or remove greenhouse gas emissions where possible. In its publication, FAO highlights the diversity of potential options across the globe and in various agricultural systems: In China, for example, a pilot project has been launched to educate yak herders and provide tools to restore degraded grasslands, improving the productivity of their herds while sequestering atmospheric carbon. In the highlands of Mount Kilimanjaro, FAO has partnered with farmers in Kenya and Tanzania to reboot an 800 year-old agroforestry system known as Kihamba, aiming to maximize the use of limited land, provide a large variety of foods throughout the year, and maintain groundwater health.Along the north Pacific coast of Nicaragua, the UN agency has introduced an ecosystem approach to fisheries and aquaculture to boost food and income from fish products, while preserving ecosystem and increase resilience to climate change. read more

Mens basketball Chris Holtmann focuses on recruiting and program tradition in opening

Chris Holtmann, the 14th coach in Ohio State men’s basketball history, speaks at introductory press conference Monday morning | Credit: Sheridan Hendrix | Oller ReporterDressed in a gray suit, white dress shirt and scarlet-striped tie, holding the hands of his wife, Lori, and his daughter, Nora; Chris Holtmann, alongside Ohio State Athletics Director Gene Smith, was formally introduced as Ohio State men’s basketball’s 14th head coach in program history in a press conference Monday on the court of the Schottenstein Center.Rumored to be a candidate at several job openings such as North Carolina State, Missouri, Pittsburgh, Georgia Tech and Tennessee over the past three offseasons, Holtmann said the Big Ten program in Columbus was the only one he seriously considered.“This was a decision I had to work through,” Holtmann said. “Gene was aggressive and persistent in his approach and I really appreciated that.”Holtmann, 45, spent the past three seasons at Butler and made the NCAA Tournament each year, reaching the Sweet 16 this past season. After that run, Holtmann signed a contract extension with Butler through the 2024-25 season. But when the Ohio State job became available and he was offered an eight-year deal worth approximately $3 million annually, he couldn’t let that opportunity slip by him.Holtmann said the combination of a university with world-class education, a thriving athletic department with some of the best programs in their respective sports in the country, the tradition of the program, a talent-rich recruiting area and a passionate fan base sold him on the position.“I had left a special program and special guys,” he said. “That was emotional for me. But I’m telling you, it was the vision that (Smith) had and what he was looking for and this place. I’m extremely excited.”The search for the replacement to 13-year head coach Thad Matta began the afternoon of June 5, coming just after it was announced Matta would be exiting. Smith met with former collegiate basketball coach Eddie Fogler to begin the process of searching for candidates and conducting background checks on any names that arose in the discussions.Smith said the search for a new head coach began and ended with the same name at the top of their list.“(Holtmann) was my target from the beginning,” Smith said.Holtmann discusses the importance of recruiting well in the state of Ohio at his introductory press conference Credit: Sheridan Hendrix | Oller ReporterThough Holtmann was offered the job on Tuesday, Smith said Holtmann was reluctant at first to sign on the dotted line. The contract originally put on the table was a seven-year offer, but Smith said he tacked on an additional year to create a more enticing offer.Then, on Thursday morning, Smith said he and his wife traveled to meet the Holtmanns in Dayton and get to know one another. By the time the discussion had ended, Ohio State had its next head coach.Smith called Fogler and told him the search was over. They got their guy.“We sought a high-intensity individual with an emphasis on academics, someone who is relentless in recruiting with great ties to the great state of Ohio and the contiguous states,” Smith said. “We found a proven winner who’s a community engager and bottom line fits our culture.”During Holtmann’s introductory speech, he emphasized the importance of recruiting the state of Ohio, highlighting his 20 years of experience recruiting the Buckeye state. He said that locking down the state’s best prospects would be paramount to the program’s long-term success.“This region … is a tremendous area for talented, smart and tough players,” Holtmann said. “We’re going to work extremely hard as a staff to close the borders and dominate the state of Ohio in recruiting. It will be an every-day focus for us.”Holtmann, who is leaving the highest-ranked recruiting class in Butler history, said that he began calling recruits immediately Friday after he signed the appropriate paperwork with the compliance department.As far as the rest of the coaching staff is concerned, Holtmann said there are “some wheels in motion” on naming the rest of his staff, but would not expound on that notion.The past four seasons, the Ohio State program has been on the decline, which has been exemplified in scoring struggles and defensive letdowns. Holtmann gave an indication of how that play might change under his leadership.“Aggressive, attacking. We want to be physical and tough and tough minded,” he said. “But we want to play aggressive, attacking style and we want our guys to play with freedom. We want them to go out there and cut loose and play. I think that’s what people will see when they watch our team.” read more

DavyMarkham awarded IAMGOLD engineering contract

first_imgThe English engineering company, DavyMarkham, has been awarded a $20 million order for the supply of mining hoists and associated electrical drives and controls by gold producer IAMGOLD of Toronto, Canada. The contract includes a large double drum hoist with a diameter of 6.4 m, a drum width of 2.4 m and a payload capacity of 20,000 kg. It will serve as the main production hoist, operating at depths down to 2,652 m, at IAMGOLD’s new Westwood exploration program. “This is a very important contract gain for DavyMarkham and it is testimony to the cutting-edge design engineering technology we are applying to this key market sector and the extreme precision of our heavy engineering,” says Managing Director, Kevin Parkin. “IAMGOLD is a major new customer for us and we are delighted to have won this major order in international competitive tender.”Over recent years DavyMarkham has been developing mine winder technology, making inroads into the Canadian minerals market, supplying, according to the company, more than a dozen new hoists for gold and nickel mining projects; it was also the first supplier to the North American market to comply with the South African SABS codes of practice, for deep shaft exploration. The company has worked closely with ABB Montreal on the provision of electrical plant for these projects and gained a thorough understanding of how its drive and control systems operate, ensuring the highest levels of safety, reliability and performance for mine hoisting installations.For the Westwood project, DavyMarkham will design, manufacture and supply a 6.4 m diameter production hoist and a 5.5 m double drum service hoist, together with associated clutch assemblies and multi-channel hydraulic brake control system. ABB has been sub-contracted to provide drive systems for both hoists, including high voltage motors, industrial drive units, digital hoist control system and a hoist operator station. Delivery is scheduled for late spring, early summer 2010, presently on a supply to mine site basis, although there may be the option of providing installation and commissioning services at a later stage.Located two kilometres from the company’s existing Doyon mine operation in northern Quebec, IAMGOLD’s Westwood advanced exploration project began in 2004 to identify potential new deposits. A raise boring machine is already excavating an initial shaft and, once this is complete, the sinking of the main 5.5 m diameter exploration shaft will begin.This accelerated exploration program puts pressure on DavyMarkham to meet an extremely tight contract deadline, although work is currently progressing to schedule. The principal components were first subject to a rigorous engineering analysis process to predict stress levels and deflections at all critical points in the hoist, with the drums themselves modelled using finite element studies, which accurately represent the thickness of materials to be used throughout the structure. This process enabled the company to recommend a smaller 5.5 m diameter service hoist with geared drive, as the optimum size commensurate with duties, rather than the more expensive 5.79 m diameter, direct drive configuration originally specified.A particular feature of the DavyMarkham mine hoist design is the provision of a multi-channel hydraulic brake control system, which ensures full SABS compliance and maximum safety under fault conditions. This system has been specified on both IAMGOLD hoists and will be interfaced with ABB’s digital hoist control equipment, so that if a fault occurs with one brake channel, only one cluster of brake units is affected and the remaining clusters provide correct brake application and controlled deceleration.On the drives side, ABB will be supplying a water-cooled ACS6000 series multidrive coupled to a 6,800 kW AC synchronous motor for the main production hoist, with an ACS800 multidrive and two 1,205 kW cast iron induction motors for the service hoist. It will also provide its well-proven digital hoist control and safety supervisory system, to monitor the hoist operating speed envelope and ensure reliable and accurate control of brake systems and other hoist subsystems. This will be linked to a Type PA1 hoist operator control station and Hoistlogger monitoring system, for a simple and clear means of mine hoist operation when full production starts in 2012.last_img read more

Weir sees strong demand for brownfield mine solutions in H1 results

first_imgWeir Minerals clocked a solid performance in the first half of 2018 and was ably supported by strong demand for new equipment and aftermarket services from its Minerals division.The company’s orders from continuing operations (minus its Flow Control division) were up 20% year-on-year in the six month period at £1.17 billion, while operating profit jumped 38% to £160 million.Minerals orders increased 12% to £728 million, with original equipment orders up 9% (£222 million) and aftermarket orders up 14% (£728 million). Operating profit within the division rose 13% to £112 million.While its Minerals division performed well, its Oil & Gas division topped it with a 35% year-on-year order jump to £438 million as North American upstream oil and gas markets grew strongly.Weir said: “Activity in mining markets continued to grow strongly as customers ramped up production to maximise the benefits of supportive commodity prices. Demand was particularly good for brownfield solutions that help debottleneck, increase throughput and reduce downtime of existing mines.”The pipeline of new projects continued to increase driven by good long-term fundamentals for commodities such as copper, gold and lithium, the company said.“Customers remained disciplined about committing to new greenfield developments, although a small number of projects received final approval.”Weir said its early investment in deploying more engineers to customer sites to help miners improve productivity had continued to support strong order growth in the first six months of the year with sales from integrated solutions, which leverage the division’s portfolio of premium products, delivering around £50 million in additional orders. Weir noted engineers completed 374 site audits in the period.“The division also continued to grow market share through its successful trials programme that sees it go head to head with competitor products to demonstrate the superior performance of Weir equipment,” the company said.The first half also saw the opening of additional service centres in Zambia, Chile and Peru to further extend Weir’s service network.Weir’s technology programmes focused on continuous improvement in the division’s core products while also developing its Synertrex® IoT solution. Weir said full commercialisation of this technology in mining markets was planned for the second half of the year.Synertrex uses network connectivity to capture equipment data and relay it to service centres, service technicians, their customers and Weir’s design centres for trend monitoring, proactive components supply and product improvement.After the end of the quarter, Weir completed the acquisition of Esco Corp in a deal that came with an enterprise value of $1.29 billion.last_img read more

GOG also bundles the game with its manual, art book, 18 wallpapers, a game guide, two maps, the soundtrack, developer interviews, 26 avatars for you to use, and even a calendar.The deal gets even better when you consider GOG is also running another promotion this weekend offering 60 percent off the price of 30 EA titles. That includes the Wing Commander, Ultima, and Populous series, as well as Theme Hospital, Dungeon Keeper, and SimCity 2000. Buy any of those at their discounted price and you still get The Witcher for free.The free copy of The Witcher will be offered on purchases until Thursday, October 17 at 9:59am GMT, which is 4:59am EST.

Half of employees with money worries believe their work is suffering as

first_imgHalf (50%) of employees experiencing financial worries believe that the quality of their work is negatively affected as a result, according to a study commissioned by pension and investment organisation Aegon.The research, based on an August 2018 YouGov survey of 505 HR decision makers from UK private sector organisations, also revealed that half (50%) of those with financial concerns believe they are less creative or less able to complete tasks that should be routine.More than two-thirds (69%) of employees say they face money worries. These can stem from feeling under-prepared for financial emergency (27%), the everyday costs of living (26%) and a lack of preparedness for retirement (21%).Steven Cameron (pictured), pensions director at Aegon, said: “Employees have told us that poor financial wellbeing is harming their productivity at work. Poor financial wellbeing is not only stressful for individuals, but it’s also costing employers millions of working days a year, and billions to the economy.”Approximately half (51%) of respondents told the survey that a lack of employee financial wellbeing, including concerns over long-term saving, retirement plans, budgeting, debt and living costs, is an issue for their organisation; 63% of large employers are concerned about their workers’ ability to save for the future.More than three-quarters (77%) of employers revealed that they are not aware of regulations around the difference between financial guidance and advice, and therefore do not know when they might be overstepping the line into advice, which can only be given by a regulated adviser. Almost half (45%) think they would be intruding by approaching employees about it.However, the research found that 70% of employees would find general information highlighting steps to improve their financial wellbeing useful, while 64% would value face-to-face counselling and support around debt management.Cameron said: “Clearly, employers want to do more to provide the help their employees need. We need to start a ‘win-win’ conversation about this issue so employees know where they can receive support, and employers feel empowered to give it.”last_img read more
