Tribute on the Passing of the Rt. Hon Edward Phillip George Seaga from the Jamaica Chamber of Commerce

first_imgJamaica has lost one of its most accomplished sons in the passing of the Most. Hon. Phillip Edward George Seaga. Few of our leaders have had his breadth of vision or have exceeded his foresight in creating and championing critical and transformative institutions that served – and continue to serve – our country well.From the HEART Trust/NTA, the Urban Development Corporation, the Jamaica Stock Exchange and the Jamaica Unit Trust; to the Jamaica Mortgage Bank, Students’ Loan Bureau, Agricultural Credit Bank, EXIM Bank and JAMPRO, Mr. Seaga’s unique imprint as a visionary institution builder, is unparalleled. These entities have had a significant impact on the nation’s social and economic environment.What is also noteworthy, and perhaps not as well known to younger Jamaicans, was that the former Prime Minister saw earlier than most, the scope for the development of Jamaica’s cultural and creative industries both as a means of celebrating the Jamaican spirit as well as a foundation for the growth of industries that would help to establish the nation as a creative hub. His role in taking ska to the wider world and in being a pioneer in the recording industry as well as in launching the Jamaica Festival movement and Things Jamaican are accomplishments that illustrate just how wide-ranging were his interests and how impactful were his contributions.This eclectic span of interests – in sport, music, art, dance, business and, of course, politics, coupled with his abiding faith in the talent of the Jamaican People – equipped him admirably for passionate service to the Country he loved so deeply.The nation is poorer for his passing. We extend our deepest condolences to his wife Carla, children Christopher, Anabella, Andrew and Gabrielle, his family, colleagues and friends.For further information please contact the JCC President, Lloyd Distant Jnr.Telephone: 876-922-0150 Email: Lloyd.distant@gmail.comlast_img read more

HBC accuses Land Buildings of misleading shareholders about Rhone investment

first_imgTORONTO – Hudson’s Bay Co. and activist investor Land & Buildings continue to accuse one another of misleading shareholders regarding the sale of the retailer’s Lord & Taylor Fifth Avenue building and a related investment by Rhone Capital.In a statement, HBC (TSX:HBC) said it has not sold a controlling interest to Rhone which agreed last month to invest $632 million in the retailer in the form of mandatorily convertible preferred shares, initially convertible into common shares at $12.42 per share.HBC said it expects Rhone will initially hold a 21.8 per cent voting and equity interest in the company on a partially diluted basis and that could grow to 30.0 per cent if the preferred shares are held to their eight-year maturity.The department store chain’s statement is a response to the activist investor’s urging that the retailer consider a bid for its German operations by Signa Holding and critique of the security issuance, which it said sells a controlling interest in the company without having sought the approval of minority shareholders.Land & Buildings called some of HBC’s comments “highly perplexing” in a statement released today and re-iterated its demand that shareholders be allowed to vote on the share issue. Such a vote is necessary to determine whether the new investment is in common shareholders’ interests.“The Rhone transaction effectively transfers meaningful and practical control of the company into a class of preferred shares that over time functionally outstrip common shareholders of their equity,” Land & Buildings said.The announcement of the investment by Rhone last month was part of a series of deals that also saw HBC sell the Lord & Taylor building in New York to WeWork Property Advisors for C$1.075 billion.last_img read more

German official says neighbours closely watching coal debate

first_imgBERLIN — A senior German official says neighbouring countries are closely watching Germany’s political debate on phasing out the use of coal.Brandenburg governor Dietmar Woidke said Wednesday that “it’s really important to create positive examples” of countries taking decisions to curb climate change.A panel of experts, including Woidke, has been discussing how and when to close down Germany’s remaining lignite mines. It is expected to deliver its recommendations to the government this month. A key question is what kind of financial support affected regions will get to tackle the transition away from coal.Woidke said Europe has 41 regions where coal is mined, including in less prosperous countries such as Poland, Slovakia and Bulgaria, and “they are looking to us to see whether we can tell a positive story.”The Associated Presslast_img read more

Government raising fines for semis that dont chain up among new winter

first_imgVICTORIA, B.C. — The B.C. Ministry of Transportation and Infrastructure announced several improvements to make B.C. highways safer and more reliable during the winter months following what has been a colder- and snowier-than-average winter.Transportation Minister Claire Trevena announced today that several changes will be going into effect for the next winter driving season, including increasing fines for commercial vehicles that don’t carry chains or don’t chain-up when required, extending winter tire requirements on certain routes prone to late season snowfall, and increasing road-maintenance contractor requirements.“I have heard from people and communities throughout the province that we need to take action to improve safety on our highways. With that in mind, our government is moving quickly to implement changes that will ensure people are able to get where they need to go more safely through the winter months.”Stricter commercial vehicle chain-up requirements are the first priority named by the government, and the the ministry says it will enforce higher fines for commercial vehicle operators not carrying chains, or who don’t chain up when mandatory. Currently, the fine in B.C. is $121, while in other North American jurisdictions the fine is up to $1,200 for similar violations, ten times higher. The exact fine amounts are yet to be determined. The government will also roll out a pilot program limiting which lanes commercial vehicles can use on certain corridors, which will reduce the risk of collisions, and blockages due to spun-out trucks. On key three-lane highway sections during winter, commercial vehicles will be restricted from using the far left lane, to ensure more reliable and safe access for the traveling public. When all lanes are blocked, the ability for emergency crews and maintenance equipment to move along the highway is eliminated, compounding the closure.Ministry staff will also be expanding monitoring and auditing of road-maintenance contractors, including 24/7 compliance checks during winter storms. Snowplows will also be getting GPS tracking.The current regulations requiring drivers to fit winter tires or chains from October 1st to March 31 will also be extended in certain areas of B.C. The ministry will expand the date range through to April 30th on select highways and mountain passes to account for potential early spring snowfall events which occur regularly in the Northern regions of the province. The exact routes where the winter tire rules will be extended has not yet been determined.Another small change announced today that could have a big impact in this part of B.C. is a reduction in the highway abrasive standard size. The government said that the standard size of grit used on roads will be decreased from 12.5 to 9.5 millimetres to reduce potential windshield damage. Across the entire province, road crews apply 750,000 tonnes of winter abrasives over 1.2-million kilometres on average every winter.Trevena is also making a trip to visit Fort St. John on Thursday, where she’ll be speaking with members from local governments in the area.last_img read more

Centre justifies law for 10 quota to economically weaker sections

first_imgNew Delhi: The Centre on Tuesday justified in Supreme Court its recent law granting 10-per cent quota for Economically Weaker Sections (EWSs), saying it was brought in to promote “social equality” by providing “equal opportunities in higher education and employment to those who have been excluded by virtue of their economic status”.The government said the new law will not be covered by the Indra Sawhney versus Union of India (popularly called Mandal Commission verdict) of 1992 as provision for reservation was made after amending the Constitution. Also Read – How a psychopath killer hid behind the mask of a devout laity!”That the Constitution Amendment (103rd) Act 2019 was necessitated to benefit the economically weaker sections of the society who were not covered within the existing schemes of reservation, which as per statistics, constituted a considerably large segment of the Indian population,” an affidavit filed by the Centre said. It said in order to do justice across all weaker sections of the society, “it was therefore considered imperative that the Constitution be appropriately amended to enable the State to extend various benefits, including reservations in educational institutions and public employment to the EWSs of the society who are not covered by any of the existing schemes of reservation…”. Also Read – Encounter under way in Pulwama, militant killedThe Centre’s affidavit was filed in connection with a matter where a batch of petitions have challenged the validity of the Constitution (103rd Amendment) Act, 2019 on the ground that it is contrary to the decision of this court in Indra Sawhney versus Union of India and violates the basic structure of the Constitution. “It is submitted that the conclusions drawn in Indra Sawhney are inapplicable to the present case as the said judgment was delivered while determining the constitutional validity of certain Office Memorandums issued by the Government of India in the year 1990, which provided for reservations for the backward classes of citizens in services under the State,” it said. The affidavit said the present challenge, however, is in relation to the validity of a constitutional amendment made wherein Article 15(6) and Article 16(6) have been inserted, which did not exist on the book when Indra Sawhney verdict was delivered. “Indra Sawhney verdict and the findings therein can therefore have no application thereafter,” the affidavit said. The Centre contended that merely affecting or impinging upon an Article embodying a feature that is part of the basic structure of the Constitution is not sufficient to declare an amendment unconstitutional. “To sustain a challenge against a constitutional amendment, it must be shown that the very identity of the Constitution has been altered,” it said. The government said the impugned amendment is in conformity with the constitutional principles and therefore does not violates the basic structure doctrine. “That in order to provide reservation to EWS without disturbing the existing reservations for SCs, STs and OBCs, the constitutional amendment has provided for a maximum of 10-per cent reservation for EWSs in addition to the existing reservations. The limit of 50 per cent is only applicable to reservation made under Article 15(4), 15(5) and 16(4) and does not apply to Article 15(6),” the affidavit said. It said several committees were set up wherein quantifiable data was collected highlighting the need for having reservation for the economically weaker sections of the society. “Accordingly, the constitutional amendments were necessitated for providing opportunities in higher education and employment to those who have been excluded by virtue of their economic status,” it said and added that it was essential that the EWS gets access to these facilities as mandated in the Constitution.last_img read more

Commentary Cleveland Cavaliers may benefit from lockout

There’s no arguing that the NBA lockout is a genuine disservice to the fans, and especially to the ordinary people who are out of work because of it. Good seldom comes from labor stoppages in any sport. The Cleveland Cavaliers and their fans may just be the rare beneficiaries. With every cancelled game comes one less guaranteed loss. Any impact the new Collective Bargaining Agreement potentially makes extends well beyond this year’s Cavaliers team. Dan Gilbert, like all the other wealthy owners who are trying to extort every last penny from the players, doesn’t have a dire need for money. Even though they are in a small market, the Wine and Gold did extremely well financially during the LeBron James era. Even without “the gutless one,” Forbes still ranked the Cavs as the 15th most valuable franchise in the NBA. The new CBA should ensure their financial stability as well. What remains to be seen are potentially the most exciting of possibilities: the likely changes to the salary cap system. A hard cap would restrict big market teams from spending gobs of money and create more parity, a word not generally associated with the NBA. Likewise, installing a harsher luxury tax would serve a similar purpose, even if team salaries above a certain threshold aren’t expressly prohibited. It would’ve been generous of the NBA and the National Basketball Players Association if they quit their posturing months ago, and had the same sort of urgency in their negotiating tactics throughout the entire process as they did in the last two weeks. Since we’ve reached the point where the NBA has already canceled games, it’s best for the Cavaliers if the owners continue their tough stance. Particularly when it comes to what they call “system issues,” making it easier for small-market teams to compete. Even in the old system, the small-market San Antonio Spurs have been among the NBA’s elite for years. They drafted well, made shrewd acquisitions otherwise, and, most importantly, kept Tim Duncan in town. Unfortunately, James wasn’t blessed with Duncan’s loyalty. If the owners get their way, the new CBA will make it easier for teams to keep their star players. It would come two years too late for the Cavs. Still, if they ever acquire a star player again, their chances of keeping him long-term will be higher. Their only hope is to build through the draft and then keep these players. No marquee free agent is looking to come to the place that “leads the nation in drifters.” Even when they had James, the “stud” free agent Gilbert recruited was Larry Hughes. That was his first step in sabotaging the team. The worst-case scenario would be the a cancellation of the entire 2011-12 NBA season. That’s almost the best-case scenario for the Cavs, who could be guaranteed another top-five pick. Generally, no fan of basketball wants to see an entire slate of games wiped out. In my world, though, I put the Cavaliers’ interests ahead of the rest of the NBA’s. The more missed games, the merrier read more

Survey School Violence Tops Social Concerns for Teen Voters

first_img Share Leya MohsinJunior at Rice Meredith McCain discusses policies and voting with fellow Houston area students. McCain helped organize the inaugural Houston Youth Voters Conference, held at Rice University earlier this fall.In an era of school violence and partisan politics, a new national survey shows that school shootings and gun laws top the list of social concerns for likely teen voters.In September, about two months before the midterm elections, the nonprofit and nonpartisan Education Week Research Center asked over 1,300 18- and 19-year-olds for their thoughts on the election.Just over 60 percent of them said they plan to vote this November, a response higher than polls from previous elections. This group said their top social concern was school shootings, like the ones in Parkland, Florida, and Santa Fe, Texas. Their number two concern: guns and gun control. Those are very different issues than those for the general population, which ranks dissatisfaction with government and immigration as top concerns.Among economic concerns, likely first-time voters said that the high cost of living and inflation worried them the most, followed by the economy in general and the gap between rich and poor.The national survey found these possible teenage voters were more likely to be liberal and less likely to identify as moderate.

Bubble technique used to measure shear forces between graphene sheets

first_img This document is subject to copyright. 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. (Phys.org)—A team of researchers from China and the U.S. has devised a relatively simple means for measuring the shear forces that exist between sheets of graphene and other materials. In their paper published in the journal Physical Review Letters, the group describes the technique and the results they found when using it to measure shear forces for several types of 2-D materials. More information: Guorui Wang et al. Measuring Interlayer Shear Stress in Bilayer Graphene, Physical Review Letters (2017). DOI: 10.1103/PhysRevLett.119.036101ABSTRACTMonolayer two-dimensional (2D) crystals exhibit a host of intriguing properties, but the most exciting applications may come from stacking them into multilayer structures. Interlayer and interfacial shear interactions could play a crucial role in the performance and reliability of these applications, but little is known about the key parameters controlling shear deformation across the layers and interfaces between 2D materials. Herein, we report the first measurement of the interlayer shear stress of bilayer graphene based on pressurized microscale bubble loading devices. We demonstrate continuous growth of an interlayer shear zone outside the bubble edge and extract an interlayer shear stress of 40 kPa based on a membrane analysis for bilayer graphene bubbles. Meanwhile, a much higher interfacial shear stress of 1.64 MPa was determined for monolayer graphene on a silicon oxide substrate. Our results not only provide insights into the interfacial shear responses of the thinnest structures possible, but also establish an experimental method for characterizing the fundamental interlayer shear properties of the emerging 2D materials for potential applications in multilayer systems. Explore further 2-D layered devices can self-assemble with precision As graphene sheets are used in more applications, it has become important to better understand the shear forces at play between them and other materials. Learning more could prevent sheets from coming apart, for example, when they are used to make an electronic device. In some applications, graphene sheets are layered with other graphene sheets, while in others, graphene sheets are applied to sheets of other materials. But until now, there was no way to measure how well such materials clung to one another. Traditionally, such measurements are made by adhering sheets of material and then pulling them in opposite directions—a means of measuring their shear force. But because graphene sheets are single atom thick, that approach is not feasible. In this new effort, the researchers have found a new way to measure shear forces between such materials.In the new method, tiny holes were drilled in one sheet before it was adhered to another sheet. Air was then used to generate pressure from below, causing the top sheet to rise and pulling the sheet below with it, forming a bubble. The researchers then used Raman spectroscopy to measure the amount of stretching at the base of the bubble as a means of measuring the shear forces between the two materials.Using their technique, the researchers were able to measure the shear force between two sheets of graphene and found it to be 40 kPa, which is considered very small and unsurprising, as sheets of graphene have been used as a lubricant. The team also measured the shear force between a sheet of graphene and a sheet of silicon dioxide, and found it to be 1.64 MPa—which is approximately 40 times greater than the shear force between graphene sheets.center_img Journal information: Physical Review Letters © 2017 Phys.org Citation: Bubble technique used to measure shear forces between graphene sheets (2017, July 19) retrieved 18 August 2019 from https://phys.org/news/2017-07-technique-sheer-graphene-sheets.html This cutaway shows the bulging that occurs when air is pumped through a hole underneath a graphene sheet.

Researchers find a core cow microbiome dictates dairy cow productivity and emissions

first_img More information: R. John Wallace et al. A heritable subset of the core rumen microbiome dictates dairy cow productivity and emissions, Science Advances (2019). DOI: 10.1126/sciadv.aav8391 Explore further As the planet continues to warm due to human-related activities, scientists continue to look for ways to reduce greenhouse gas emissions. In this new effort, the researchers wondered if it might not be possible to reduce the amount of methane released by cattle. Livestock have been found to contribute up to 14.5 percent of such gases worldwide. Far less methane is released into the atmosphere each year than carbon dioxide, but methane is better at trapping heat.The researchers note that prior research has shown that the primary generator of methane in cows is the rumen—the first stomach. When a cow eats grass, it goes into the rumen, where a host of microbes reside along with other digestive materials. The host microbes work together to break down the carbohydrates via a fermentation process. As part of that process, hydrogen is produced by certain types of bacteria, and then archaea combine carbon dioxide with the hydrogen to produce methane. Contrary to common belief, most of the methane is belched out of the cow’s mouth.To find out if cows could be coaxed into producing and belching less methane, the researchers conducted a genetic analysis of the microbes that exist in the rumen of several types of cows from several sites across Europe. In all the team collected samples from more than 1000 cows. Study of their rumen microbiome showed that half of all of the microbes in them had 512 species in common. They also found that 39 of the microbes made up a core that plays a major role in determining not just how much methane is produced, but also how much milk. The researchers are now looking into the possibility of manipulating the cow rumen biota to see if it is possible to bring about changes that will result in less methane production.
