CBCs new drama Caught like a grownup Doyle

first_img Login/Register With: “Don’t take this the wrong way,” said Maggs, “but it feels like a grown-up ‘Doyle.’” Their latest project is “Caught,” a five-episode drama premiering Monday on CBC. It is grittier, more complex and much darker than “Doyle.” Facebook Two years ago, Allan Hawco was working on a script for a TV series when he asked another writer — fellow Newfoundlander Adriana Maggs — to read an early draft and give an honest opinion. That was exactly the reaction Hawco was hoping for. For six seasons, he starred in, and was the driving force behind, the lighthearted CBC detective series “Republic of Doyle.” The success of that series helped Hawco and his associates at Take the Shot Productions establish a production facility in St. John’s, N.L. The cast all had praise for costume designer Michael Ground’s low-key approach. The series is based on the 2013 crime novel of the same name from another talented Newfoundlander, author Lisa Moore. The novel, shortlisted for the Scotiabank Giller Prize, was handed to Hawco at a studio meeting as a suggestion for his next project. “I hadn’t read it, which was weird,” says the 40-year-old actor/producer, “because the author lives up the street.” He read it, loved it and got in line for the rights.center_img Advertisement LEAVE A REPLY Cancel replyLog in to leave a comment Advertisement Advertisement Twitter Set in 1978, “Caught” tells the story of David Slaney (played by Hawco) who busts out of a New Brunswick prison and quickly hooks up with his former drug-dealing partner in crime (Eric Johnson from “Fifty Shades Freed”).

Christie Administration accused of cronyism in health care contract awards

first_imgFacebook Twitter Google+LinkedInPinterestWhatsAppBahamas, June 16, 2017 – Nassau – More millions promised within the final weeks of the ousted PLP Administration and the bills are left with the Bahamian public to pay.  When the Health Minister spoke, he talked about how the previous government left$25M in unpaid bills for medical equipment, rent, drugs and salaries at the Ministry of Health and the Public Hospital’s Authority.Minister, Dr Duane Sands claimed that even more surprisingly, despite the Christie Administration knowing of their IOUs, the PLP still entered into over $9.7M worth of security contracts, janitorial contracts, generator purchases and other miscellaneous items … Minister Sands said the contracts were with, and I quote, “people who may be considered the party faithful.”Shockingly, the Princess Margaret Hospital had a shortfall of $16.5M, critical work was stopped at the PMH he says, 67 beds were taken out of service at the PMH, and for an Abaco clinic not yet opened, the PLP was found, says Sands to have awarded contracts – $500,000 per month to clean the unopened clinic and $26,000 per month to landscape the grounds at that unopened clinic.#MagneticMediaNews#cronyisminhealthcarecontractawards Related Items:#cronyisminhealthcarecontractawards, #magneticmedianews Facebook Twitter Google+LinkedInPinterestWhatsApplast_img read more

JAMAICA Nurses Charged to Play Greater Role in Promoting Public Health

first_imgFacebook Twitter Google+LinkedInPinterestWhatsApp Related Items: Facebook Twitter Google+LinkedInPinterestWhatsApp#Jamaica, March 1, 2018 – Kingston –  Minister of Health, Dr. the Hon. Christopher Tufton, has charged the nation’s nurses to prepare to play a greater role in promoting and protecting public health.  He noted that nurses, given the regular and frequent contact they have with people, are in a unique position to promote healthy lifestyles and advise persons against habits that can endanger their health.“The nursing profession has to prepare itself… (for nurses) to be greater advocates for the cause of public health and wellness in our society,” he said.The Minister was addressing the launch of Nursing Now, a global campaign aimed at promoting the profession, held on Tuesday (February 27) at the Bustamante Hospital for Children in St. Andrew.  The initiative is geared at, among other things, raising the status of nurses globally, and maximising the contribution that nursing makes to universal health coverage and women’s empowerment and economic development.Its key partners are the World Health Organization (WHO), International Council of Nurses, the United Kingdom (UK)-based Burdett Trust for Nursing, and nursing organisations across the globe.Minister Tufton, in endorsing the campaign, said it is going to reinforce the value of the nursing profession to public health locally, in the region and internationally.  He noted that the impact of nurses is greatest at the level of primary healthcare; the preventative side of health, which is a major thrust of Governments globally.“It is a good time to highlight, to reinforce that importance, in order for us to take note and to do more to promote the interest, role and the contribution of a very crucial sector in the delivery of public healthcare,” he said.Dr. Tufton said the initiative will enable “greater empowerment of our nurses and provide them with the ability and the capacity to prepare themselves to provide greater leadership, as an important response to the public health challenges the country faces”.last_img read more

Fuel Cell to Power Connecticut Sub Base

first_img Dan Cohen AUTHOR Officials last week held a groundbreaking at Naval Submarine Base New London, Conn., for a 7.4-megawatt fuel cell park adjacent to the base’s power substation, part of an effort to improve the installation’s energy resiliency and cut its energy costs. Connecticut-based FuelCell Energy will sell the power generated by the fuel cells to the Connecticut Municipal Electric Energy Cooperative, which oversees the local grid and has entered into a 20-year purchase power agreement with the Navy, reports the Day. The fuel cell park will meet a majority of the daily needs of the base, with any excess power being exported to the Groton Utilities distribution system, according to a press release.“It is designed to compete with the grid, and be better than grid power, but it’s also about resiliency and the reliability of having power locally on base,” said Tony Rauseo, senior vice president and COO of FuelCell Energy, which is designing, manufacturing and overseeing the installation of the fuel cell park.Day photo by Tim Martinlast_img read more

Hey Google I want a sound bar that also streams Netflix

first_img Tags Now playing: Watch this: JBL Link View gives Google Assistant a smart screen with… 2:58 Best sound bars under $300 Comment TVs Audio Media Streamers Preview • JBL Link Bar brings Google Assistant, better TV sound for $400 JBL Offering both Google Assistant and Android TV, the JBL Link Bar is one of the most feature-packed, and most delayed, sound bars on the market. Originally scheduled to debut in 2018, JBL’s voice-controlled combo sound bar-streaming box is finally on sale for $400.  The JBL Link Bar is a do-everything Frankenstein: an HDMI-connected sound bar that offers Google Assistant voice control in addition to streaming content via Google’s own Android TV system. Android TV is similar to the more popular Roku and Amazon Fire TV systems, with direct access to apps including Netflix, Hulu, ESPN and thousands more. The system is available on devices such as the Nvidia Shield and Sony smart TVs, but this is its first appearance built into a sound bar. The Link Bar appears to be based on the company’s earlier smart sound bar, the Link 300, which doesn’t offer video streaming. It has three 4K-compatible HDMI ports and an HDMI ARC output, plus it has built-in Chromecast for multiroom streaming from phones and Chrome browsers. The company also offers an optional subwoofer for $300.For those who don’t like the idea of having a live microphone in the house, the Link Bar also includes a feature called PrivacySwitch the company says will “ensure the highest level of security and privacy and leave hackers out of the house.” The Link Bar is late to the party, and at least two competing products offer compelling alternatives, though neither offers video streaming. The first is the Polk Command Bar, which was designed in conjunction with Amazon, incorporates Alexa and includes a subwoofer. The second is the Sonos Beam, which has both Alexa and Google Assistant plus the well-established Sonos ecosystem. Look out for a review of the JBL Link Bar in the near future.  1 18 Photos JBL Link Bar Review • JBL jams Google Assistant and Android TV into a sound bar Amazon Google Share your voicelast_img read more

Skateboarding at the 2020 Olympics Everything you need to know

first_img Now playing: Watch this: The eclectic sport of skateboarding will debut at the 2020 Olympics in Japan. Carroll Photo/Getty Images Skateboarding, a rebellious street sport, will debut at the 2020 Olympics in Tokyo. Often seen as renegade or rebellious, characterized by dizzying midair twists and turns, skateboarding will make its way into the structured and mainstream world of the Olympic Games. Though the International Olympic Committee (IOC) unanimously supported skateboarding for inclusion at the 129th IOC session in Rio de Janeiro in 2016, not all skateboarders feel the same way. Some athletes have expressed gratitude and excitement at the idea that skateboarding will get more exposure as a sport, while others worry that the Olympics will damage the culture and lifestyle that accompany it. I suppose no one will know how the sport might change until the Olympics arrive next year, but for now, you can read all about the structure, scoring and qualifications process for skateboarding at the 2020 Olympics.  Skateboarder jumping at a skate park.The park discipline will feature a course that resembles a large basin with lots of dips, twists and turns. Daniel Milchev/Getty Images What will the event be like? Skateboarding at the Olympics features two disciplines: park and street.  The park competition will take place on a hollowed-out course featuring a complex series of twists and turns. Park courses resemble large bowls with steep sides, nearly vertical at the top. Skaters send themselves to dizzying heights, performing jaw-dropping spins and tricks midair, and then gracefully bring themselves back down to the bowl to do it all over again on the other side.  The street competition features a straight course with stairs, handrails, benches, walls and slopes to mimic a real street. This kind of skateboarding is characterized by riding along curbs and rails, leaping into the air without using hands, and that familiar grind of board on metal.  Olympic skateboarders will experience at least some of the creative freedom they get in their home parks and streets: They’re free to choose which parts of the course to cover and, of course, which tricks to perform. Also, in an attempt to maintain the feel of the sport, music will accompany each rider.  Only one athlete rides at a time, and competitors get three timed runs to post their best score. Young men skateboarding in urban environment.The street discipline mimics what it’s like to skateboard in a city environment. The course will feature rails, benches, curbs and other things you’d find on a real street. MoMo Productions/Getty Images How do athletes qualify to skateboard at the 2020 Olympics? The IOC has allotted 80 quota spots for skateboarders at the 2020 Olympics. There will be 40 spots for women across the two categories and 40 for men, with 20 skaters in both the street and park competitions for each gender. Between the 80 qualifying athletes, 38 men and 38 women will come from different nations, with four total slots (two men and two women) reserved for the host nation of Japan.  Each National Olympic Committee (NOC), the governing body for each country’s Olympic goings-on, is allowed six men and six women for skateboarding, but no more than three athletes per gender per event.  Qualifications are managed by World Skate, the international governing body for roller sports.  Like all other Olympic sports, skateboarders must comply with the Olympic Charter to be eligible. Aside from that, the qualifying pathway for each event (20 athletes) is as follows:  Three athletes will directly qualify as the highest-ranked skaters in the 2020 Season World Skate World Skateboarding Championship events.16 athletes will qualify through the Olympic World Skateboarding Rankings (OWSR) as of June 1, 2020.One athlete will qualify as the allocated host nation slot. This person is the highest-ranked skater in the host nation; in this case, Japan.There are 16 available slots to fill via the OWSR, but no nation can fill more than three. For example, the US may have five skaters in the top 16, but only the first three of those five will qualify. Once a country’s three spots are filled, the qualification moves down to the next country that hasn’t fulfilled its quota. Learn more about the qualifications process.  When and where is the skateboarding event? Olympic skateboarders will compete in Tokyo at the Aomi Urban Sports Venue, which will also host 3×3 Basketball and Sport Climbing. The competition takes place throughout the entire Games, from July 24 to Aug. 9.  How will athletes be judged? Judges will score athletes based on speed, difficulty, originality, timing, stability and the overall flow of the performance. One important skill judges will be looking for is the ability to seem suspended in midair.  0 Share your voice Fitness Sports Tags Intel developing 3D Athlete Tracking for Tokyo 2020 Olympics Post a comment 3:36last_img read more

Highlevel USN Korea nuclear talks get underway

first_imgUS Secretary of State Mike Pompeo departs after meeting with North Korean envoy Kim Yong Chol in New York, US, on 30 May 2018. Photo: ReutersHigh-ranking officials of the United States and North Korea met in New York late on Wednesday in the first of two days of talks about the future of Pyongyang’s nuclear weapons programme and a possible summit between US president Donald Trump and North Korean leader Kim Jung Un.US Secretary of State Mike Pompeo and Kim Yong Chol, a close aide of North Korean leader Kim Jung Un, met for about 90 minutes over dinner and exited without providing any detailed remarks to reporters waiting outside.Pompeo would only say that the dinner “was great” and that the two men dined on “American beef.”It was not yet known whether the two men made any progress toward narrowing long-standing differences between Washington and Pyongyang that could end decades of hostile relations.Earlier in the day, the White House left open the possibility of a Trump-Kim summit on 12 June in Singapore, despite Trump’s cancellation of the meeting just days ago.As the dinner was underway inside an apartment on New York’s East Side, just south of the United Nations, a senior State Department official separately briefed reporters on the high-level talks that were underway.Pompeo and Kim Yong Chol, vice chairman of the ruling Workers’ Party’s Central Committee, “are trying to get to know each other” following their two initial meetings this year in North Korea, said the US official who asked not to be identified.The official added that before any summit between the two leaders can occur, Pyongyang is “going to have to make clear what they are willing to do” amid demands from Washington that North Korea permanently end its nuclear weapons program.Trump, the official said, “can make a fly or no-fly decision anytime he wants,” referring to the possible unprecedented Singapore summit.If not enough progress is made to lead to a productive meeting between Trump and Kim Jung Un, the official said, “We will ramp up the pressure on them and we’ll be ready for the day that hopefully they are ready.”Shortly before Wednesday’s dinner, Pompeo repeated the Trump administration’s bottom-line demand:“Looking forward to meeting with Kim Yong Chol in New York to discuss @Potus potential summit with Chairman Kim. We are committed to the complete, verifiable, and irreversible denuclearisation of the Korean Peninsula @StateDept,” Pompeo said in a Twitter post.Trump last week called off the summit after North Korea expressed anger at comments by senior US officials. But Trump later said he was reconsidering his position and US, North Korean and South Korean officials have gone ahead with summit preparations.The White House said on Wednesday that negotiations at the demilitarised zone along the border between North and South Korea for the summit were going well.Separately on Wednesday at Pearl Harbour in Hawaii, Admiral Harry Harris, the outgoing head of US Pacific Command who is Trump’s pick to be the ambassador to South Korea, said North Korea remained the United States’ most imminent threat. “And a nuclear-capable North Korea with missiles that can reach the United States is unacceptable,” Harris said.Earlier, a US official said negotiations about the summit’s agenda have so far been slow going, and the two fundamental issues, the definition of North Korean denuclearisation and whether both sides would take actions at the same time or separately, remained unsettled.‘Denuclearisation’Trump has sworn not to allow North Korea to develop nuclear missiles that could hit the United States and wants North Korea to “denuclearise,” or get rid of its nuclear arms.But the leadership in Pyongyang is believed to regard nuclear weapons as crucial to its survival and has rejected unilaterally disarming.The Trump administration, according to US officials, has left open the possibility of North Korea eventually getting US aid and investments if Pyongyang agrees to complete denuclearisation.North Korea’s position going into the meetings with Pompeo was that a pledge of denuclearisation alone should open the way to economic relief, said the official who briefed reporters earlier on Wednesday and spoke on condition of anonymity.South Korea’s Yonhap news agency quoted Seoul’s Unification Minister Cho Myoung-gyon as saying in a speech on Wednesday that the differences between North Korea and the United States on the denuclearisation issue remained “quite significant” and it would not be easy to narrow the gap.However, Cho added that the engagement of the leaders of the two countries meant “chances are high that common ground can be found.”Kim Yong Chol is the most senior North Korean official to meet top officials for talks in the United States since Jo Myong Rok, a vice marshal, met then-president Bill Clinton at the White House in 2000.A former military spy chief, he has played a central role in the thaw in relations over the past six months between North Korea and South Korea, as well as the United States.North Korea defends its nuclear and missile programs as a deterrent against what it sees as US ambitions to overthrow its leadership and unite the Korean Peninsula. The United States stations 28,500 troops in South Korea, a legacy of the 1950-1953 Korean War.last_img read more

With the help of AR, users can practice blocking penalty kicks from a life-size goal, including some that approach with 80 miles per hour — speeds that Naeher will be facing once the World Cup officially starts later this week.Gannett and USA Today emerging technology director Ray Soto readily admitted that he hadn’t been able to block any of those super-fast balls either when he demonstrated the experience at the sidelines of the Augmented World Expo in Santa Clara, Calif. last week. “You really don’t know where this is going to go, but I don’t think Alyssa does either,” he said. Soto said that his team initially just planned to include those 80 mph shots in the experience, but quickly realized that this would be too overwhelming for most users. That’s why the experience now also includes a much more manageable training phase, as well as an intermediate stage with balls coming in at 40 mph.The entire experience is modeled after real penalty kicks, tasking users to block 5 shots. It is being narrated in part by Naeher herself, who Soto’s team recently got to scan and turn into a 3D AR hologram. “Team USA and Alyssa were fantastic,” he said.In addition to the goalkeeper experience, USA Today is also launching a second AR component, which introduces Team USA on the field in a tabletop-like setting. Soto said that the app would be constantly updated to reflect any changes in Team USA’s line-up. The two-part AR experience went  live within USA Today’s iOS and Android apps Tuesday.center_img Popular on Variety last_img read more

Flexible Polymer Transistors Printed Using Ultraviolet Light

The content is provided for information purposes only. Study results pave the way to programmable electronic inks The procedure for creating UV-printed polymer transistors. (a) A PEDOT-coated mold is placed in contact with the pre-polymer-coated flexible substrate (b) They are illuminated with UV light (c) Upon removing the mold, PEDOT source-drain layers are transferred onto the substrate (d) Active and dielectric layers are “spin coated” on top of the source-drain layers (e) and (f) Using a PEDOT-coated glass substrate, the self-aligning gate layer is contact-printed on the dielectric layer. Image by Hong Lee, © American Institute of Physics (PhysOrg.com) — Computer and television displays made using flexible, bendable polymer materials are technologies of the future, promising roll-up computer monitors and other innovations. Scientists are making progress toward bringing these technologies into our homes and offices. A research group at Seoul National University in Korea recently created a flexible polymer transistor that is printed using a simple process involving ultraviolet (UV) light, described in the November 20 online edition of Applied Physics Letters. Creating transistors in this way is an important avenue toward flexible electronics, as transistors form the basis of most modern electronic devices. Computer processing chips, for example, consist of more than 200 million transistors.”Our printing method is low-cost and could be scaled to the manufacturing level — a requirement for most technologies,” said Hong Lee, the paper’s corresponding author, to PhysOrg.com. “It performs as well as non-flexible polymer transistors and better than similar transistors produced by other research groups.”The researchers started with a commercially available polymer mold etched with a “source-drain” pattern, forming locations for two of the three electric terminals that make up a transistor: the source, drain, and gate. They then coated the mold with a very thin layer (just 100 nanometers) of a conducting polymer material, known in abbreviated form as PEDOT.Next they coated a flexible substrate — a surface on which to build the transistor — with a “pre-polymer” liquid layer. The pre-polymer is key to the process because it hardens and binds to the PEDOT layer when illuminated with UV light.Applying no pressure, the researchers brought the mold and the substrate into contact and exposed them to UV light for 20 minutes. When the mold was removed, the researchers saw that the PEDOT on the mold’s raised areas had been transferred to the substrate, forming the transistor’s source and drain.But unlike ink deposited onto paper by a stamp, in which the paper’s surface remains flat, the substrate underwent topological changes caused by the physical bonding between the pre-polymer and the PEDOT under the UV light during the hardening process. Where the raised parts of the mold met the substrate, the substrate’s surface developed “low” areas. And across from the mold’s low areas, the substrate developed a raised mound between the source and drain, which acts as a channel between them.The substrate was coated with two additional polymers, an “active” current-carrying layer and a dielectric, a material used in transistors to control the flow of current.Finally, the substrate was flipped over and put in contact with PEDOT-coated glass. PEDOT “ink” was transferred to the substrate’s raised area, completing the four-layer printed transistor structure.This method departs from the inkjet-style approaches commonly used to print polymer transistors, in which a printer head moves back and forth across the substrate, depositing the polymer layers in tiny droplets. Inkjet printing has been successful, but ensuring the overall transistor pattern is properly aligned before the ink is dispensed can be difficult. The UV method does not require this step because the formation of the raised mound after the mold and substrate are combined and illuminated acts as a self-alignment mechanism.Citation: Applied Physics Letters 93, 203308 ( 2008) link.aip.org/link/?APPLAB/93/203308/1Copyright 2008 PhysOrg.com.
