first_imgThe proposed fee increases for the 2017 Budget, coupled with over 100 taxes being increased in recent months has brought on “new pressures” to the Guyanese populace including workers, pensioners and other ordinary citizens who stand to face the brunt of the burdens.This is the contention of the Federation of Independent Trade Unions of Guyana (FITUG) which noted on Tuesday that upon its examination of next year’s Budget, it has concluded that Government has “woefully fallen short” of its promise of “Delivering the Good Life to All Guyanese”.Members of the Federation of Independent Trade Unions of Guyana (FITUG)“Budget 2017 puts the masses of Guyanese at a severe disadvantage and will certainly worsen the already bad social conditions in the country,” FITUG stated.In fact, the union group expressed that the Budget will only serve to engender even “greater hardships on our already overburdened working-class”.Chief among the concerns raised by the body included the introduction of Value Added Tax (TAX) on electricity and water; the reduction in the number of VAT exempt and zero-rated items which will impact medical supplies and services, and treatments; the introduction of an environmental tax; the increases in the costs of passports; the introduction of fees for TIN certificates; the massive increases in the costs for a number of licences, fees and penalties and the increase in the departure tax.“The latest burdens to be added comes just a few months after the Government increased about one hundred and forty (140) taxes, some as high as 1,200 per cent. Worst yet is that more are still to come, such as the introduction of parking meters (In Georgetown) and the rumoured increases of rates and taxes, land lease fees and the Demerara Harbour Bridge tolls,” FITUG highlighted.FITUG has also determined that the Budget is “sorely lacking”, noting that there are “hardly any specific details or policies” to address the country’s rising rate of unemployment.“Moreover, the Federation was also dismayed to learn that the Budget did not address, in a positive way, the plight of the sugar workers. For two years now, thousands of workers and their families are being forced to contend with no pay increases. That aside, the workers are faced with other assaults on their rights and benefits. In the face of such denials, it is damning that large sums are being found to fund super-salaried Government officials and the top echelons of the sugar industry and, possibly, soon a former high office holder,” the statement read.It was further pointed out that Budget 2017’s “draconian measures” can be seen as an anti-working class Budget. The Federation further noted that this current Budget will “undo many of the positive gains made in the past years” and serve to push many ordinary Guyanese into an “impoverished state”. FITUG urged the President David Granger-led Administration to re-look, with a view to rescind, the many measures which will be “severe blows on and badly hurt the people, especially the poor and working people of our country.” As the Budget debates got underway earlier this week, Chairman of the Parliamentary Public Accounts Committee (PAC) Irfaan Ali, called on Government to immediately withdraw the Budget. Ali had further suggested that Government would do well to sit with the Opposition Peoples Progressive Party/Civic (PPP/C) in order to craft a better Budget. He further expressed that the Budget presented was littered with inaccuracies regarding economic performance and is saturated with an extensive range of new punitive taxes.last_img read more

first_imgBut, no more caramel apples, hot dogs, live bands and field trips this fall. The ranch usually opens in mid-August and stays open until Halloween. On Sunday, as hundreds of people picked out pumpkins, rode ponies and walked through The Maze, those wicked winds started blowing things over. Joann Lombardi, who owns the ranch with her husband, Bob, said she wanted to close because it was just too dangerous. The evacuation started at 2:15 p.m. and everyone was out about 30 minutes later, she said. Teenage employees took kids home, helped customers get across the street and directed traffic, Lombardi said. SAUGUS – Lombardi Ranch – a longtime Saugus landmark scorched and closed by the Buckweed Fire – is reopening today in time for its Halloween rush. “Our kids didn’t want us to give up,” owner Joann Lombardi said Wednesday. “They have worked so hard to get us open.” Customers who stop by the roadside stand can still buy pumpkins, corn, tomatoes and take a train ride through a sunflower field dubbed Scarecrow Alley. Although the fire cooked many of the pumpkins, the Lombardis still have 75 tons in their fields. “They did exactly what they were told,” she said, lauding the teens. “Some of them didn’t want to leave. I made them leave.” Animals – including a horse, donkeys, ponies, an emu, a llama, pigs and chickens – were let out of their pens. “After the fire, they all came back and into their pens,” she said in disbelief. Lombardi said she watched as the fire made its way to within about 300 feet from the wooden stand, originally constructed in 1966. One daughter, who lives on the ranch, lost her home to the fire. It was the house that Bob Lombardi, 62, had grown up in. “We lost things, but we still have our family,” said Joann Lombardi, 61. When Lombardi Ranch opened in 1966, Joann and Bob Lombardi had one 18-month daughter. Today, they count four grown kids and 10 grandkids. Joann Lombardi said she has been trying to get her husband to retire for several years, but he wants to keep farming. She said it has been a frustrating year with rain, road closures and now the fire. When she pushed to close the business, the couple’s three daughters and son balked. “My kids got really mad at us,” Joann Lombardi said. “They said, `People are depending on you.”‘ “I stood back and let my sisters do the complaining,” said Rob Lombardi, who built the trains that chug their way around the ranch. Friends also want to see the ranch stay open. “You don’t want the tradition to die,” said Beth Oliva, a longtime friend who straightened up scarecrows for today’s opening. “There are some things you can’t replace.” Lombardi Ranch means family time, the Saugus resident said. Oliva’s boys, ages 16, 15 and 11, have been coming to the ranch since they were born. “You just know Lombardi,” Oliva said. “It’s a part of Saugus. It’s a tradition out here.” The Lombardis plan to stay open until Halloween. “After that, I don’t know,” Joann Lombardi said. “It is up in the air.” jerry.berrios@dailynews.com (661) 257-5253 — Ranch hours Lombardi Ranch will be open 9 a.m. to 6 p.m. daily until Tuesday. It will close at 5 p.m. on Halloween. The ranch is at 29527 Bouquet Canyon Road.

first_imgMr Downey todayCommenting after a court decision ruling that the prosecution of John Downey was an abuse of process and should not continue, Sinn Féin MP Francie Molloy said: “The arrest and charging by the British police of John Downey was a clear breach of commitments given by the British government at Weston Park and in subsequent negotiations.“Following the Good Friday Agreement both the British and Irish governments accepted that the issue of those defined as OTRs was an anomaly and the two governments committed to resolve the issue. “A process was put in place to deal with outstanding cases including that of John Downey. Sinn Féin made it clear from the outset that the decision to prosecute John Downey was the wrong one.“This position has been vindicated by the decision of the judge ruling in John’s favour. John Downey should now be allowed to return home to his family immediately.“Sinn Féin will continue to support John and his family until this happens.”The party said that John Downey is a valued member of Sinn Féin and a long-time advocate of the Peace Process.For over two decades John Downey has been to the fore in promoting the peace process. As a former republican prisoner he has been involved in Cultural Diversity programmes with former loyalist prisoners. And he participated in engagements at Corrymeela with former members of the RUC, Gárdai and Irish Army.JOHN DOWNEY: ‘HE IS ADVOCATE FOR PEACE AND SHOULD NEVER HAVE BEEN CHARGED’ was last modified: February 25th, 2014 by John2Share this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:courthyde park bombJohn DowneySinn Feinlast_img read more

first_imgCARBONDALE, Ill. – The Drake University women’s basketball team closes the regular season at Southern Illinois on Saturday with tipoff against the Salukis scheduled for 2 p.m. The game will be available online via The Valley On ESPN3.Drake, who recorded its 20th overall win of the season with a 20-point victory over Evansville on Thursday, holds a 13-4 record in Missouri Valley Conference action. The Bulldogs have now earned back-to-back 20-win seasons for the first time since the 2000-01 and 2001-02 seasons.Drake and Missouri State (20-9, 13-4 MVC) are tied for second place in the MVC while SIU is fourth at 19-10 overall and 12-5 in MVC play. UNI (19-9, 14-3 MVC) has clinched at least a share of the league title. Drake needs to defeat SIU and have Evansville beat UNI on Saturday for the Bulldogs to earn a share of the regular season title with the Panthers. Missouri State hosts Illinois State on Saturday as the final day of the regular season will determine not only the title winner but seeding for next week’s MVC Tournament held March 10-13 at the iWireless Center in Moline, Ill. The Bulldogs along with the Bears, Panthers and Salukis have each clinched a top four seed and will all play on the second day of the tournament.The Bulldogs were led by the MVC Preseason Player of the Year junior Lizzy Wendell (Blue Springs, Mo.) in their win over Evansville. Wendell poured in a game-high 22 points while junior Caitlin Ingle (Runnells, Iowa) equaled her career mark with 15 assists. Ingle has now handed out 15 assists in a game three times in her career, a mark that ranks tied for the third most in a single game in school history. Freshman Sara Rhine (Eldon, Mo.) scored 19 points, including nine points in the final four minutes against the Purple Aces and sophomore Maddy Dean (Jordan, Minn.) just missed a double-double with 16 points and eight rebounds. Drake finished with 29 assists on 35 field goals. The Bulldogs’ bench scored 33 points while the team had 56 points in the paint.SIU lost to UNI on Thursday by a score of 73-64 as the Salukis had three score double figures, led by senior Dyana Pierre with 16 points. SIU edged Drake, 77-67, in the league opener for both teams on Jan.1 in Des Moines.The 2015-16 MVC Tournament is scheduled for March 10-13 at the iWireless Center in Moline, Ill.

first_imgScience is messy, but it doesn’t have to be dirty.On June 19, a group of respected energy researchers released a paper in the journal Proceedings of the National Academy of Sciences (PNAS) that critiqued a widely cited study on how to power the U.S. using only renewable energy sources. This new paper, authored by former NOAA researcher Christopher Clack and a small army of academics, said that the initial 2015 study had “errors, inappropriate methods and implausible assumptions,” about using only the sun, wind, and water to fuel the U.S.What followed was a storm of debate as energy wonks of all stripes weighed in on the merits of the PNAS analysis. Mark Z. Jacobson, a Stanford University professor who was the lead author of the 2015 study, shot back with detailed rebuttals, in one calling his fellow researchers “fossil fuel and nuclear supporters.”Why the big kerfuffle? As an energy researcher who studies the technologies and policies for modernizing our energy system, I will try to explain.In general, getting to a clean energy system — even if it’s 80% renewable — is a well agreed-upon goal and one that can be achieved; it’s that last 20% —and how to get there — that forms the main point of contention here. The nitty-grittyTo make projections around how the future energy system will work, researchers create computer-based models, input assumptions, and then run simulations.The rebuttal from Clack and his co-authors focused on four major issues they saw with the WWS paper: 1) modeling errors, 2) implausible assumptions, 3) insufficient power system modeling, and 4) inadequate scrutiny of the input climate model, which informs how much solar and wind power are available for power generation. Here are some highlights with my own thoughts sprinkled in.Clack takes issue with the amount of hydroelectric power that Jacobson assumes is available. In their rebuttals, they spar over the exact numbers, but Jacobson assumes there will be about the same amount of total energy produced from hydropower in 2050 as today, although when, and at what rate, that energy is produced is a crucial question.In Jacobson’s model, there is a significant increase in hydropower capacity — up to 1,300 gigawatts (or about 10 times current capacity), which appears to run for at least 12 hours straight in some days of the model output. Jacobson says this is possible by installing more turbines and generators at existing dams, just not using them very often.But dams are built with specific maximum flow rates because if you let too much water flow through a dam, you can flood areas downriver. Jacobson has since admitted that providing this much extra power from existing dams would be hard.I recently took a tour of Hoover Dam. One of the first things the tour guides tell you is that the dam was built for irrigation and flood control, and that electricity production is a nice side product. So expecting that dams in the country could boost their output might be harder than the analysis implies. Joshua Rhodes is a post-doctoral researcher of energy at the University of Texas at Austin. This post originally appeared at The Conversation. ‘Energy Twitter’ on fireJacobson’s seminal paper, which was also published in PNAS, tied together a significant amount of work of his own and others showing that all energy used for all purposes in the U.S. could come from with wind, water, and solar (WWS) by 2050.What about when the sun doesn’t shine, the wind doesn’t blow, or water is unavailable? His findings postulated that significant amounts of energy storage would be needed, mostly in the form of heat and hydrogen, to meet energy demand when there isn’t enough renewable energy and to store it when there’s too much. Jacobson and his co-authors also concluded that this scenario would be cheaper than a world that relies on other technologies such as nuclear, carbon capture, and other methods of reducing carbon emissions.The Clack rebuttal was blunt and cut deep at the assumptions that underlie the work of Jacobson and colleagues. The same PNAS issue also included a counter-rebuttal to Clack from Jacobson.Energy Twitter — that is, energy wonks like me on Twitter — exploded.So why all the fuss?Much of the heat from this debate seems to stem from Jacobson making some pretty bold claims in and about his paper, going so far as to tell MIT Technology Review that “there is not a single error in our paper.” That is a very, very bold claim and, depending on how it is interpreted, could be read to say that the study authors’ model is perfect, which of course it is not, as none are.This debate may seem arcane, but it has significant political and societal implications.Some celebrities have signed on to Jacobson’s vision and have pressed for policies formed around his analyses of the feasibility of an entire energy system that runs 100% on wind, water, and solar. If policymakers buy into the technical and economic assumptions in the paper, those assumptions will have big implications for the direction of state, local, and national policies.Detractors, meanwhile, have raised a number of concerns. In particular, they argue that decisions made based on Jacobson’s analyses alone could lead to serious over-investment in only the technologies considered, which could possibly backfire if the costs turn out to be higher than expected. The Cheapest Way to Scale Up Renewable Energy?Transforming the Electric SystemSolar Potential Is Far Greater Than Earlier EstimatesRethinking the GridTo Improve Wind and Solar Power, Bring Them Together How Renewable Energy Advocates Are Hurting the Climate CauseOur All-Renewable Energy FutureAccounting for Renewable Electricity SavingsWind Overtakes Hydro as Top Renewable in U.S.Government Estimates on Renewables Are Way Offcenter_img Insufficient power system modelingClack attacks LOADMATCH, the power system model in Jacobson’s analysis, as being too simplistic. The main criticism of LOADMATCH is that it does not consider frequency regulation — the need to keep the frequency of the power grid steady at 60 Hz, which is a very important aspect of keeping the power supply reliable.One piece of anecdotal information: Jacobson states in the paper Supplementary Information that it takes LOADMATCH about three to four minutes to simulate an entire year. Our simulations of just the Texas electricity market can take hours to run, and can take significantly longer for simulations of high levels of renewables.After reading both papers, both supplementary information sections, the counter-rebuttal, a lot of news articles and tweet-storms (from other energy folks I trust), I find myself thinking that the burden of proof is still in Jacobson’s court. There are many lessons to learn here.But, in the end, my view is that the body of scientific understanding will be stronger for it. The peer review process is slow, uses imperfect human volunteers, and doesn’t always get it exactly right the first time. The list of authors on the Clack rebuttal is impressive, and should be paid attention to. However, if Jacobson’s work can survive this challenge, I figure it will stand the test of time. Implausible assumptionsClack questions a long list of input assumptions of Jacobson’s model. A number are related to how quickly technologies can mature and be used at large scale, including underground thermal energy storage, phase change materials to store solar thermal energy, and hydrogen as a usable fuel. Other critiques focus on assumptions around how flexible the demand for energy can be — a key consideration when dealing with variable sun and wind power. Then there’s the amount of electric transmission power infrastructure needed, the costs of all the capital required, the pace of investment needed, and land use issues.Some criticisms are probably fair. I tend to be bullish on the potential of technology to advance rapidly, but having worked in residential energy use, and energy retrofits in particular, I find that Jacobson’s assumptions about the amount of geothermal energy storage retrofits for heating and air-conditioning in buildings are hard to fathom.I have some reservations on the ability of 67% of demand to be flexible. I also have some questions on the pace of investment required in Jacobson’s scenario. RELATED ARTICLES last_img read more
