Tumbler Ridge Museum reopens

first_imgDr. Tom Perry, a Vancouver medical specialist who led the pledge drive at the 3D Medical Conference, said he was excited that visitors to Tumbler Ridge helped raise a substantial contribution toward keeping the museum open.“The Peace River Palaeontology Research Centre and Tumbler Ridge Museum are not just provincial, but national treasures,” said Dr. Perry. “I think that the doctors, pharmacists and other health professionals attending our course recognized the tremendous value of this resource for science and education, and want to see it thrive over the long term.”Dr. Helm said that the Foundation’s long-term goal remains to work with municipal and regional governments to secure stable funding from the Province. TUMBLER RIDGE, B.C. – Officials with the Tumbler Ridge Museum Foundation say that after being closed since March due to financial difficulties, the Tumbler Ridge Museum was able to reopen its doors last weekend.Foundation spokesperson Dr. Charles Helm said that the Museum was able to reopen on June 14th after the Foundation was able to secure additional funding in the past couple of months. In early May, the District of Tumbler Ridge, which had denied the Museum’s application for $200,000 in grant funding earlier this year, offered the Foundation $50,000 to open five days a week during the summer tourist season. This followed a ‘challenge grant’ of $50,000 from The Dalglish Family Foundation, challenging government and other funding sources to contribute funds, with the Foundation’s goal to raise $150,000.Dr. Helm said that over $20,000 was pledged by the attendees of the Drugs, Dinos and Dinner Medical Conference held in Tumbler Ridge earlier this month. Kelly McManus and Roachelle LaPrairie pledged a substantial personal donation, supported by sizeable contributions from LaPrairie Crane and Northland Fleet. The Lions Club of Tumbler Ridge then came forward with a further major contribution. Coupled with a contribution from the District of Tumbler Ridge, Dr. Helm said that the goal had been reached.last_img read more

BJP leader shot at in East Burdwan

first_imgKolkata: A BJP leader from Bhatar in East Burdwan was attacked by some unidentified miscreants.The incident occurred on late Saturday night when the victim, Krishnakali Samanta, was sitting on the courtyard of his house. He sustained bullet injuries in his right leg when the miscreants opened fire at him. As he raised an alarm the accused fled from the spot. The family members of the victim rushed him to Burdwan Medical College and Hospital, following the incident, which has triggered tension among the local residents. The district BJP leaders alleged that Trinamool Congress leaders in the area might have been involved behind the attack. The family members of the victim also alleged that Trinamool-backed goons had attacked the victim, as he has been instrumental in strengthening the party organisation in the Bhatar area. District Trinamool leaders however have denied the allegation and termed the incident a result of infighting within BJP.last_img read more

Trump meets with Twitter CEO amid bias complaints

WASHINGTON — President Donald Trump says he had a “great meeting” Tuesday with Twitter CEO Jack Dorsey after bashing the company profusely earlier in the day.Trump and some Republicans in Congress have complained that social media giants are biased against Republicans, something the companies have rejected as untrue.Trump gave his readout of the meeting on Twitter, writing: “Lots of subjects discussed regarding their platform, and the world of social media in general. Look forward to keeping an open dialogue!”While some tech company executives may lean liberal, they have long asserted that their products are without political bias.Trump had tweeted earlier Tuesday that Twitter didn’t treat him well and that he would have more followers “if Twitter wasn’t playing their political games.”Kevin Freking, The Associated Press read more

Crew snap threegame losing streak electrify in shutout

Columbus Crew forward Federico Higuain (33) scores on a penalty kick against New York Red Bulls goalkeeper Luis Robles in the second half at Crew Stadium in Columbus, Ohio, on Saturday, August 10, 2013. The Crew won, 2-0.Federico Higuain scored two goals to propel the Columbus Crew to a 2-0 win over the New York Red Bulls Saturday night in their first home game since PrecourtSports Ventures purchased the team on July 30.The victory snapped a three-game losing streak for the Crew. It was the third time this season they have triumphed over a first place team, and the other two wins have also come at home. The Red Bulls fell to second in the Eastern Conference standings with the defeat.“It’s tough to play against a team like this. With a good performance and a little bit of luck, you can win the games,” said Crew coach Robert Warzycha during a press conference after the match.Higuain’s first goal Saturday came on a penalty kick opportunity after Red Bulls goalkeeper Luis Robles was flagged for contact in midair while defending a Crew free kick.The goal was the Higuain’s fifth from the penalty spot this season and seventh overall.Robles guessed and dove to his right and Higuain easily scored kicking to the opposite corner.If the Red Bulls had any beef with the officiating that set up the first goal, they could have found no fluke or flaw inHiguain’s second goal, notched in the 76th minute.The Argentine team captain caught Robles venturing dangerously far out of his goal, and he chipped the ball from 20 yards away into the upper left corner of the goal with a skillful crossing shot.Rookie center defending midfielder Wil Trapp was credited with the assist, his first as a pro.“If you score goals like the second one that Pipa (Higuain’s team nickname) scored, I mean, that’s why we come into the stadium. That’s why we’re coaching, that’s why we’re playing. We’re looking for goals like that,” said Warzycha.Ohio State alum Matt Lampson served capably in goal for the Crew in place of the injured Andy Gruenebaum, making key saves throughout the game.The Red Bulls have had success late in games, with 12 goals after the 75th minute of play this season. Lampson’s late save of a Jonathan Steele shot helped the home team avoid having to claw their way back from a deficit.“I didn’t see it until really late, and credit to him because that was a hell of a shot. I just got my body in the way and swung a flipper at it, and luckily, it went off the crossbar,” said Lampson in a postgame interview.On the whole, however, The Red Bulls weren’t as aggressive as the Crew throughout the match. From early on, the away team failed to engage the Crew’s core of backs during defensive possessions, preferring instead to sit back and wait for the ball to come to their side of the field.Along with Viana and center back Josh Williams, Trapp and fellow University of Akron product Chad Barson anchored the defense and controlled the tempo of the game with methodical passing and turnover-free ball handling.Trapp spoke after the game about what the Crew did wrong two weeks ago—when they lost to Toronto FC on the road—that they were able to do right Saturday night. The Canadian squad visits Columbus next Saturday in the tiebreakingthird matchup of the rival teams this season.“Tonight, from front to back, it was a complete performance. We closed out the game. That’s something we didn’t do in the Toronto game. In the second half, we didn’t attack anymore. We sat back and let them attack and attack. When you keep absorbing those waves of pressure, it’s going to be tough to keep out a goal. Tonight, we did a good job of having the mindset that once we get one, we’ve got to get two. That was definitely key, and I think if we transition that to Toronto, we’re going to have a good shot at winning the game,” said Trapp.Crew Stadium observed a pregame moment of silence in commemoration of former Crew player Kirk Urso, who passed away on Aug. 5, 2012, from a congenital heart defect at age 22.Owner Anthony Precourt participated in the pregame coin toss.As for the Crew securing a win at home in front of new ownership, Lampson said, “Every single player on the field today came and they brought it. And Mr. Precourt can be very pleased with what we have, and I think it’s a sign of the things we’re capable of. He can have lofty goals because that’s what we can do as a team.” read more

Diablo III expected April 17

first_imgBlizzard is expected to officially confirm the release date of Diablo III in the very near future, and all the evidence now points to an April 17 release for the highly anticipated third game in the series.Although not confirmed officially, apparently several major retailers across Italy have been told by Activision to ensure they have shelf space ready for April 17. That was closely followed by Amazon’s Italy website listing the game with an April 17 release date, but then it got removed soon after. A phone call from Activision perhaps?A few days ago Blizzard game director Jay Wilson confirmed to a fan on Twitter that the Diablo III launch announcement was imminent, scoring it a 9 on a scale of 1 to 10, with 10 meaning “imminent.” If retailers are being informed of the April 17 date, then we should surely have official confirmation of the release from Blizzard within the next couple of days. With the Game Developer Conference currently underway in San Francisco, it seems fitting that such an announcement be made before it ends on the 9th. In fact, announcing it on the 9th as GDC ends could work well.Diablo III has been delayed a couple of times now and was originally meant to ship in 2011. Then the game got pushed back to early 2012, and it was later suggested the title may not appear until June. An earlier April release would certainly be welcomed by fans, obviously. A word of warning to anyone rushing out to buy the game, though. According to Blizzard’s community manager it might not be awesome.More at mmorpgitalia (translated) via Joystiqlast_img read more

Google Fiber TOS says no servers just like every other TOS

first_imgWhat was once believed to be a miracle in the form of crazy fast internet from Google is now starting to look like a different kind of prison for advanced users.Net neutrality is a concept that gets thrown around quite a bit to describe the freedoms that we deserve as internet users. The base of the concept is really simple: we’d like the service providers to simply not care what we’re doing with our connections to the net, as long as we’re not harming the network. Don’t throttle or block our connection to sites and services that you as the provider don’t approve of, and don’t try to tell consumers what hardware or software they can use in their own homes. Google has been a huge proponent of net neutrality in the past, so when their terms of service (TOS) for their own ISP service included language that suggested servers wouldn’t be welcome in the Fiberhood it ruffled a few feathers.In the term so service for a Google Fiber connection is an agreement that states users will “not host any type of server” without express written permission from Google. The definition of a server is the first thing that comes to mind as soon as you read this. While it is possible Google is only referring to the guy who has a rack in his living room that holds a blade cluster supporting a massive piracy ring, servers come in all shapes and sizes today. You can take a $35 Raspberry Pi and make it a server for your own personal RSS service, you can host a server on your PC for a friendly game of Castle Crashers with three of your friends from around the world, and some people even use servers to access their home security systems when they aren’t at home. There’s so much in the world today that falls under that category that it seems a little odd Google wouldn’t be more specific in their TOS.Wired recently reported on a response Google gave to the FCC when they were questioned about this sweeping generalization in their agreements, and rather than clarifying their position on servers the company defended their stance entirely. Google feels that this language is completely reasonable, and falls in line with the same policies of many major providers in the industry. When this was questioned further in Google Fiber forums, several employees further blurred the line by assuring users that this didn’t apply to things like Minecraft servers, and as long as your server was legal and non-commercial you wouldn’t have any problems. It would appear that the decision to act on your violation of the Google Fiber TOS is entirely based on whatever the employee responsible for making the final decision thinks is alright to have connected to their fiber lines from your house.It stands to reason that Google would implement steps to assure that their fiber networks aren’t being abused. That imaginary guy with the blade cluster in his living room could cripple a local fiber node, or consume 77TB of data in a month just because they can. Google has to hold themselves to the same standards as the rest of the industry in order to protect themselves from users with malicious intent. This language is part of every ISP’s terms to make it easy for the company to take action against child pornographers or running the world’s largest TOR server. It’s also there in the event that someone runs their own Email server and gets taken over by a spambot without their knowledge, and is largely the reason most ISP’s offer a business class connection to advanced users.Most users won’t be affected by this anti-server statement, but the hope was that Google would be bringing a fresh take on running an ISP to the US instead of doing what everyone else is doing.last_img read more

Ireland to decriminalise small amounts of drugs

first_img Facebook Twitter: @NeosKosmos Instagram Ireland will move towards decriminalising substances including heroin, cocaine and cannabis as part of a “radical cultural shift”, the country’s drugs minister has said.Aodhán Ó Ríordáin, the chief of Ireland’s National Drugs Strategy, told a lecture at the London School of Economics on Monday that drug users will be able to inject in specially designated rooms in Dublin from next year.The minister said attitudes to drugs needed to move away from shaming addicts to helping them and emphasised there was a difference between legalisation and decriminalisation.It would remain a crime to profit – from either the sale or distribution of illegal drugs – but drug takers would no longer be criminalised for their addictions.“I am firmly of the view that there needs to be a cultural shift in how we regard substance misuse if we are to break this cycle and make a serious attempt to tackle drug and alcohol addiction,” said Mr Ó Ríordáin.However, while Mr O Ríordáin told The Irish Times that there was a “strong consensus that drugs across the board should be decriminalised,” he said it would be for Ireland’s next government to discuss.His comments follow a leaked report from the United Nations Office on Drugs and Crime, appearing to call for a worldwide decriminalisation on 19 October.The report was reportedly withdrawn after at least one nation put pressure on the international body to bury the findings of Dr Monica Beg, chief of the HIV/AIDs section of the UNODC in Vienna. Discussing plans to open ‘injection rooms’ Mr Ó Ríordáin said they would be “clinically controlled environments” that would aim to prevent already vulnerable individuals from exposing themselves to further risks.He added: “Research has shown that the use of supervised injecting centres is associated with self-reported reductions in injecting risk behaviours.”Following the opening of the Dublin clinic, the minster added he hoped similar rooms in Cork, Glaway and Limerick would also open.Source: Independent, Irish Timeslast_img read more

Man 27 arrested in Washougal homicide investigation

first_imgA 27-year-old man came into the Washougal Police Department early Monday morning and was arrested for suspicion of murder several hours later.It’s unclear whether Benjamin Wayne Walker was turning himself in when he stopped by the station at 5:45 a.m. and made contact with an officer, but Washougal Cmdr. Allen Cook said it was “something along those lines.”Walker provided officers with information, which prompted them to do a welfare check at a house in the 3300 block of H Street, Cook said.“Based on what he told them, other officers went there and confirmed there was a deceased person,” Cook said.Other residents were inside the home and were not aware of the incident until officers arrived, according to Washougal police.The death of a 78-year-old woman was determined to be suspicious, prompting a homicide investigation, Cook said.Detectives interviewed Walker and by 1 p.m. Monday, officers arrested him on suspicion of first-degree murder.“In light of how tragic the incident is, it’s been a swift investigation,” Cook said.Cook said police would not release the identity of the woman until the Clark County Medical Examiner’s Office positively identified her. The agency, which is also tasked with determining the cause and manner of the woman’s death, had not yet done so by Monday.Cook would not comment on the relationship between Walker and the woman, but said that Walker was staying at the residence.“It’s not a stranger-type crime, they were well known to each other,” Cook said.Detectives with the Clark County Sheriff’s Office Major Crimes Unit are assisting Washougal police in the investigation.last_img read more

At CES 2019 LG on juggling AI smarts and protecting our personal

first_img Share your voice 3:01 Smart Home Security Preview • Mycroft wants to be your smart-home’s brain Now playing: Watch this: All the cool new gadgets at CES 2019 CES 2019 Mycroft Smart Home AI Platform What the heck is LG’s ThinQ AI? LG executive David Vanderwaal shows off a homebrew machine and talks AI. Angela Lang/CNET For the past two years, LG has talked up the prospects of artificial intelligence. At CES 2019, the company pushed its ThinQ AI platform forward by allowing it to give you personalized recommendations based on your usage pattern. But that means collecting your data at a time when consumers are waking up to the fact that tech companies have been exploiting our personal information — sometimes with disastrous results. David Vanderwaal, senior vice president of marketing for LG Electronics’ US arm, as well as the main presenter at today’s CES 2019 press conference, helped break down how the company’s AI platform works, the issue of data privacy and why consumers should care. The following is an edited transcript of our interview. Tags 0 Q: What the heck LG ThinQ?Vanderwaal: LG ThinQ is our artificial intelligence platform that allows not just individual devices to react to commands, but also takes user data, lifestyle data, and pulls them together to make consumers’ lives easier and more enjoyable. So how does this work?LG’s vision for AI takes what we call lifestyle data, and that’s going to allow us to look at things like how our products are used in the home. For example, what television shows you watch, how often you do laundry, what type of clothes do you wash, how often do you clean your home. All those are combined with both internal and outside environmental factors to learn what users’ specific circumstances really are, and from there, offer proactive suggestions based on that user’s lifestyle.Does that mean you’re collecting our data?With LG, data privacy is extremely important to us, so the way that we’re protecting it is in a hybrid manner. So, their individual usage of that device is stored on the device only. But the aggregated data of how users use the device altogether is stored on a cloud. So always privacy is protected for the individual consumer. How else is LG protecting our information?Consumer data and the privacy to it is extremely important to LG. Everything is opt in. 85 Photos Post a comment Why should consumers care about AI?The challenge with all of us who are trying to explain artificial intelligence to consumers is what are the benefits? We’ll use a lot of use cases to actually show consumers what kind of lifestyle benefits they’ll see when they use artificial intelligence. Like what?A great example of ThinQ platform is understanding that a consumer washes clothes every Saturday. By knowing every Saturday, the AI platform, called LG ThinQ, is gradually accumulating what the behavior is and offering suggestions for how to get better washing.Is this all just a gimmick?With LG, we’re trying to make artificial intelligence relevant. Because right now, there’s a lot of artificial intelligence that consumers are using and not even knowing it. So we’re trying to make it simple to understand and show the benefits of why artificial intelligence will help products. And to communicate the idea of products communicating with one another.

DPS Troopers Assisting In Effort To Locate Thousands Of Missing CPS Children

first_imgTexas Department of Family & Protective ServicesSpecial agents with the Department of Public Safety are being used to locate an estimated 2,800 children who have been deemed by the state as at high-risk for abuse.  The DPS began assisting Child Protective Services in their efforts following a fiery meeting at the state capitol and a legislative ultimatum.As heard on Texas Public RadioPatrick Crimmins with the Texas Department of Family and Protective Services, the group who oversees CPS has confirmed that fewer than two dozen DPS special agents are working in Houston, Dallas and San Antonio, going door-to-door to find these kids, taking a picture on their phone, and sending it to a CPS caseworker.“I mean it’s kind of a welfare check kind of thing is what it is for the most part, but it is on a very limited basis, it’s only going to be Dallas, Houston and San Antonio,” Crimmins explains.Crimmins says DPS special agents are just there to “put eyes” on these children and lack the necessary jurisdiction to investigate children’s claims of abuse at this level unless they believe a crime has occurred.The emergency relief follows a tense hearing at the state capitol on Wednesday where senate lawmakers like Houston State Senator John Whitmire demanded the new head of CPS, Hank Whitman, take immediate action to find these at-risk children that no caseworker has seen in months.“Excuse me, you just said that they haven’t been seen, well hell they may die before you get there,” Whitmire told Whitman.Kate Murphy with the non-profit Texans Care For Children calls the effort a temporary fix of a much bigger problem because even after DPS special agents have located these children an individual CPS caseworker still has to conduct a follow-up visit with hundreds of families.“I think we need to start working right away with some real fixes to investigations, including hiring more caseworkers for investigations and paying higher salaries to stop turnover,” Murphy says.The head of CPS has requested the legislature allow his agency to hire an additional 550 caseworkers before the start of the 2017 legislative session.State lawmakers have demanded the head of Child Protective Services turn over his plan for turning the agency around by the end of Thursday.Copyright 2016 KSTX-FM.

Pyroelectric nanogenerator charges Liion battery with harvested energy

first_img(Left) A photograph of the PENG, (center) the PENG powers an LCD for more than 60 seconds, and (right) a green LED is powered by a Li-ion battery that was charged by the PENG. Image credit: Yang, et al. ©2012 American Chemical Society Explore further The scientists, Ya Yang and Sihong Wang from the Georgia Institute of Technology in Atlanta, Yan Zhang from the Georgia Institute of Technology and the Chinese Academy of Sciences in Beijing, and Zhong Lin Wang from both institutions, have published a paper on a pyroelectric nanogenerator in a recent issue of Nano Letters.The scientists call the device a pyroelectric nanogenerator (PENG) because it’s based on the pyroelectric effect, in which an anisotropic material’s polarization changes in response to temperature fluctuations, which can be used to harvest thermal energy. Unlike the Seebeck effect, which is used to harvest thermal energy based on the temperature difference between two ends of a device, the pyroelectric effect occurs in environments where the temperature is spatially uniform but changes over time.”Wasted heat is a rich source of energy that can be harvested,” Zhong Lin Wang told Phys.org. “In 2010, for example, more than 50 percent of the energy generated from all sources in the US was lost mainly in the form of wasted heat, which presents us with a great opportunity to harvest this type of energy using nanotechnology. Harvesting thermoelectric energy mainly relies on the Seebeck effect, which utilizes a temperature difference between two ends of the device for driving the diffusion of charge carriers. The presence of a temperature gradient is a must for the conventional thermoelectric cell. However, in an environment where the temperature is spatially uniform without a gradient, such as the outdoors in our daily life, the Seebeck effect is hardly useful for harvesting thermal energy arising from a time-dependent temperature fluctuation. In this case, the pyroelectric effect is the choice, which is about the spontaneous polarization in certain anisotropic solids as a result of temperature fluctuation, but there are few studies about using the pyroelectric effect for harvesting thermal energy.” More information: Ya Yang, et al. “Pyroelectric Nanogenerators for Driving Wireless Sensors.” Nano Letters. DOI: 10.1021/nl303755m (Phys.org)—The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new area of research is that scientists have yet to find a method that can harvest very large amounts of energy. However, the technology is steadily improving, as demonstrated by the development of a nanogenerator that can partially charge a Li-ion battery by harvesting energy from temperature fluctuations in the environment. Ancient effect harnessed to produce electricity from waste heat Journal information: Nano Letters To date, PENGs have had output voltages below 0.1 V and current below 1 nA, which are too low to drive any commercial electronics. Here, the researchers demonstrated that a PENG made of a lead zirconate titanate (PZT) thin film has an output voltage of up to 22 V, a current peak of 430 nA, and a current density of 171 nA/cm2 when exposed to a temperature change of 45 K at a rate of 0.2 K/second. The PZT thin film is 21 mm long, 12 mm wide, and 175 μm thick – about half the size of a postage stamp.With these improvements in voltage and current, a single output pulse of the PENG could continuously power an LCD for longer than 60 seconds; in comparison, a piezoelectric nanogenerator, which harvests mechanical energy from the environment, can power an LCD for about 2 seconds. To expand the potential applications of the PENG, the researchers wanted to store the electric energy it generated from temperature fluctuations. So they hooked it up to a Li-ion coin battery, and demonstrated that the PENG could charge the battery from 650 to 810 mV in about 3 hours. They then showed that this stored electric capacity could be used to power a green LED for a few seconds.Another potential application of PENGs is wireless sensors. The researchers explained that wireless sensors can be powered by a rechargeable Li-ion battery with a voltage of 2.8 V. However, the PENG fabricated here has too small of a current to do this, since the current cannot completely overtake the battery’s inherent self-discharge. The researchers predict that doubling the area of the PZT film would double the current, and increasing the thickness of the PZT film could also increase the current. These improvements could make the pyroelectric nanogenerators attractive for driving wireless sensors, LCDs, and other small electronic devices, just by harvesting the temperature changes in the environment.”In our living environment, temperature change can come from an air-flow-induced drop in room temperature, the cycled heat generation near an engine, sunlight illumination with a moving shadow, on and off hot water/air flow in a pipe, etc.” Zhong Lin Wang said.Currently, the researchers are continuing to improve the PENG’s output power and are also integrating the technology with some existing products to demonstrate its practical applications.

Grupo Modelo changes plastic rings for cardboard starting with Tulum

first_imgMexico City, Mexico — In a pilot program, one of Mexico’s largest beer producers says they are going to switch plastic rings for cardboard in a bid to take part in eliminating plastic use in the country.Grupo Modelo announced a pilot program that consists of changing the plastic packaging rings used for their six-packs with a fibrous cardboard for their Corona products. The company says the purpose is to gradually reduce the use of plastics in the manufacturing process.Clarissa Pantoja, director of Corona in Mexico, reported that the pilot program will begin in January 2019 in Tulum in coordination with the organization, Parley for the Oceans.“We look for solutions that have a big impact in the industry like changing the rings. This can become a new standard to reduce the use of plastic,” said Clarissa Pantoja, referring to the idea that they hope to eliminate plastics from all Grupo Modelo products.The new fibrous cardboard rings are made of plants, are 100 percent free of plastic and when it comes into contact with water, decomposes into an organic matter that is not harmful to wildlife. Pantoja explained that the material also has a maximum duration of 200 days, which means that it degrades faster than any other material used in the industry.Pantoja commented that this process of change begins first with Grupo Modelo’s largest brand, Corona beer and that Tulum’s selection is due to “the global impact of the Mexican beach.”Corona is the first beer brand in the world to use this type of packaging, she added.

first_imgYouth travel company Student Flights has introduced unlimited annual leave for consultants who meet the agreed commission average over the prior six months.The company’s Never Stop Travelling mantra is now as much about its agents as its customers, through the innovative approach to creating a more attractive and efficient workplace.Student Flights general manager Sean Martin said the unlimited leave initiative was designed to reward staff, attract and retain high quality candidates, increase productivity and improve the customer experience.The initiative is being rolled out Australia-wide by Student Flights, ahead of a possible wider launch within parent company the Flight Centre Travel Group.“This program enables our staff to never stop travelling, to enhance their passion and product knowledge which can then be passed on to the customer so they have all the information needed for the best holiday possible,’’ Martin said.“It is also about encouraging work-life balance while giving our consultants ownership and responsibility and developing a high-trust relationship with staff.If consultants who qualify for the perk have used their entitled days of annual leave, they can go into negative annual leave balance with no cap on that negative balance. The negative balance will be wiped back to zero at the anniversary of the consultant’s start date.“Staff can take as much annual leave as they like as long as it fits in with the business’s requirements,” Martin said.
