FNMs first budget presentation Economy worse than PLP said

first_img Related Items: Facebook Twitter Google+LinkedInPinterestWhatsAppBahamas, May 31st 2017: DPM and Finance Minister Peter Turnquest in his maiden Budget Communication said the economy is bleaker than expected; $400M worse than stated.In making the FNM Government’s first Budget presentation since taking oath two weeks ago, Minister Turnquest says while he cannot justify the actions of his predecessors, coming into office has presented the situation bleaker than they first imagined, and says the former administration left a bare cupboard.The Finance Minister says the Perry Christie Administration misled the people of Bahamas by initially stating debt at $100M, however Minister Turnquest says in actuality it stands at a staggering $500M.The debt is attributed to expenditure incurred post Hurricane Matthew, and to policies implemented in days just before the lead up to the May 10th polls.The situation, Minister Turnquest says, has caused the FNM government to defer its manifesto plans for tax relief measures until a decrease in the country’s fiscal burden.Minister Turnquest says however, some reduction in taxes will be implemented.The Opposition PLP will no doubt challenge this report when it gets a chance to speak during Budget Debate.  Members of the party are already on record accusing the Minnis-led administration of misleading the public.#MagneticMediaNews#BudgetPresentation20172018#FinanceMinisterPeterTurnquestSaysEconomyWorstThanPLPSaid Facebook Twitter Google+LinkedInPinterestWhatsApplast_img read more

Measuring Your App Usage

first_imgWhat Gets Measured?Metrics are similar to what publishers have been tracking on the Web, plus a few extra unique to the mobile platform: unique users, unique sessions, type of device, OS version, as well as location-based metrics.There are three macro areas to focus on:Interaction Rate: This is the rate of people who have downloaded the app and actually use it. If your app produces a high volume of dynamic content, you’d want to see a corresponding interaction rate.Engagement Rate: The next step beyond interaction. What are users looking at and reading? You want to track what sections of content users are reading, how many stories within that section are getting read, and so on.Feedback: This, says Peterson, is what more publishers should be doing. “Have a feedback mechanism,” he says. “Let users have that conversation in the app and then measure the net negative and positive feedback.”There are plenty of ways to drill deeper—what’s getting read, which writers are the most read, and so on—but the platform is so new, publishers should for now be concentrating on what works and what doesn’t.Transparency and ParticipationSarah Ohrvall, who just swapped her leadership role at Bonnier’s Swedish R&D group to head up R&D for the U.S. division, has taken a dual approach to analytics. Ohrvall has spearheaded Bonnier’s development of the Mag+ platform, which Popular Science uses for its iPad edition and which also has its own analytics capabilities baked right in—a prescient move given the recent problems posed to developers by Apple which is currently, according to the language in its Developer Agreement for its upcoming 4.0 operating system, barring third-party in-app measurement software.Ohrvall says analytics can work to the benefit of the publisher and the consumer. She’s looking forward to a day where users can present a “media consumption profile.” In other words, the analytics that are collected on the back end to help drive content, usage and design decisions for the publisher can also be used to enhance user experience and identity, creating a social aspect around content consumption. “Creative publishers can display that data in an interesting way to the consumer,” she says. “We’re trying to find ways to collect analytics that will be a benefit to the user.”More Than Just MetricsMeasuring key interaction and engagement metrics is one thing, says Ohrvall, but those will only go so far. “Of course you need metrics, but [time spent] won’t give you all the right numbers. You can measure what they do, but you can’t see what they don’t do and want to do. This is completely new. We need to understand the behavior behind the numbers,” she says.In that sense, Ohrvall has set a priority to learn about behavior in a context outside of the device itself—in the inherently participatory Web. The transparency of Mag+ carries over to product development as well. Product videos have been posted to the Web. Bloggers are given a peek at production and encouraged to offer opinions and foster discussion. Meanwhile, Ohrvall is watching the Web conversation closely. “We’re getting lots of useful feedback,” she says. “We’re tapping into people’s understanding of the media and their reactions to using it.”On top of that are layered the quantitative tactics and focus groups. “The Web has evolved into a participatory culture and there are ways to use that,” says Ohrvall. Publishers developing apps for mobile and tablet devices have some choices among analytics service providers—as well as some strategic decisions about how that data will be used.Developers can embed third-party measurement software that is integrated and shipped with the app and tracks a variety of usage patterns. The landscape of service providers ranges from outfits like Omniture, WebTrends and Google Analytics, to smaller firms such as Flurry, Localytics and Motally.The bigger providers offer mobile measurement as an add-on to the Web-measurement services publishers may already be getting from them. “It basically prices the same as your fixed Internet,” says Eric Peterson, founder of Web analytics consulting firm Web Analytics Demystified. “You’re tracking events, pages views or clicks, but you basically pay the same rate for mobile apps.”The smaller firms, and Google Analytics, offer free measurement capabilities as well as more robust, fee-based enterprise versions. Localytics, for example, bases their enterprise pricing on the number of active users in any given month. This number can fluctuate, and publishers tend to begin with the free services to benchmark usage before upgrading to an enterprise-level service.last_img read more

Tata Motors shares fall 10 over disappointing Q3 results weakness to persist

first_imgGuenter Butschek, Tata Motors’ CEO and Managing Director, poses with a Hexa car during its launch in Mumbai, India, January 18 2017.Reuters fileTata Motors reported a huge dip in its consolidated net profit for the third quarter (Q3) on Tuesday, resulting in its share price crashing almost 10 percent on Wednesday. The stock hit an intraday low of Rs 441 before recovering to trade 7.70 percent lower at Rs 450 on the BSE at around 10.15 am even as a brokerage warned of sustained weakness for a longer duration.Read: Confused on what is TAMO? All you need to know about Tata Motors new sub-brandThe company’s consolidated net profit for the third quarter had fallen 96 percent to Rs 112 crore as against Rs 2,953 crore in the corresponding period last financial year. Consolidated revenues also dropped 4.3 percent YoY to Rs 67,484 crore in comparison to Rs 70,567 crore in the year-ago period.Its overseas business, Jaguar Land Rover (JLR) were hit by operational weakness and huge foreign exchange losses, according to the company.”The operating performance in the quarter reflects  lower wholesale volumes and less favourable product mix partially offset by favourable market mix (including the runout of Discovery); unfavourable variable marketing expense including the extended 16MY runout expenses in the US; higher new model launch costs and Biennial pay negotiation settlement and unfavourable unrealized FX and commodity hedge revaluation as well as USD debt revaluation,” Tata Motors said in a regulatory filing.Weakness to persist, says Motilal Oswal SecuritiesIn a note, brokerage Motilal Oswal Securities Ltd. (MOSL) said the company’s foreign exchange losses would continue for another nine to 12 months. “Fx hedge losses would remain at similar levels (assuming stable GBP) for next 3-4 quarters. As a result, near term EBITDA margins are expected to be 10-11 percent, though management guided for sustainable margins at 14-15 percent,” MOSL analysts said.Brexit, Trump and Tata MotorsSlashing its earnings per share (EPS) for Tata Motors, the brokerage said the double whammy of weak domestic commercial vehicle sales and political uncertainty in Britain triggered by Brexit need to be watched out for, besides developments in the US.”In near term, two political events pose risk to our estimates, further GBP (Great Britain Pound) depreciation if Article 50 is triggered resulting in formalizing Brexit, and further development on import taxes in US.” The reference is to protectionist policies being contemplated by the Trump administration that implies encouragement to domestic production and tariff barriers on goods produced outside the country.

Bengaluru water crisis will only worsen as governments chase wrong policies

first_imgDay Zero in Bengaluru.ReutersBengaluru’s water shortage is a topic that has grabbed intense focus over the years. Everyone agrees that rapid expansion of India’s Silicon Valley has led to alarming depletion of water sources. Yet very little has been done over the years to address the basic problems. The latest projections say Bengaluru will run out of groundwater by 2020 due to the fast pace of growth and urbanisation. However, the authorities are turning a blind eye to the core issues even as the ‘Day Zero’ is almost here. A quick examination of the mess reveals that misplaced policy priorities have worsened the problem over the years. A conversation the International Business Times had with the Indian Institute of Science Professor TV Ramachandra reveals that governments have missed the bus when it comes to preventing the looming water crisis.Professor TV Ramachandra, who is part of the Energy and Wetlands Research Group, was the first to warn that Bengaluru is likely to be the next Cape Town due to the water crisis. He reveals that the situation at hand is critical. As much as 81 percent of the 746 sq km area of Bengaluru is concretised currently. In comparison, during the 1970s, 68.7 percent of the city was covered in green. Between 1973 and 2017, concretised areas have increased 1,028 percent, while 88 percent of green cover and 79 percent of water bodies have been lost. Government should take up cost-effective measuresWhile it’s clear that rampant development has led to the depletion of water sources and the deterioration of the environment, what’s more disturbing is the fact that the proposed solutions are not the right ones. According to Prof Ramachandra, Bengaluru receives 700-800 mm of rainfall but rainwater harvesting is not being implemented adequately. Nearly 15 TMC of water can be saved through rainwater harvesting, but instead of looking at these options governments have been chasing multi-crore projects like Mekedatu, Sharavati and Yetinahole.The most efficient way to conserve water is to rejuvenate the lake and retain the rainwater. If the lakes in Bellandur and Varthur region are desilted 5.4 TMC of water can be stored in the region Corruption The solution for burning civic issues mostly runs into bureaucratic and political corruption. Not just Bengaluru but 370 districts in the country are under drought. The mismanagement of water sources and unplanned urbanisation have taken people to the brink. Water for daily use is getting costlier every year and the tanker mafia is choking city dwellers. At the same time, the government is not looking at cost-effective measures but taking up multi-crore projects.Desilting of lakes, watershed management, recycling and reusing of wastewater should be implemented widely by the government, according to experts. Water contamination affecting healthNot just the quantum of water but the quality of it is also a problem in large urban areas. Vegetable and fish samples taken from lakebeds reveal a high level of contamination. “We took food samples from Bellandur area including fish, spinach and mint. All had the presence of heavy metal and it gets reflected in health in the form of cancer or kidney failure. The environmental literacy in Bengaluru is only 3.5 percent although we have educated people all around the city and the ecological degradation is linked to it,” says Prof Ramachandra. KSPCB monitor displaying water qualityAmal RasheedaliHe also highlights the fact that the BBMP data on water quality is all but flawed. When asked about the water quality data shown on LED screens installed around the city, the expert pointed out that the data could be flawed. “The BWSSB secondary treatment plant cannot remove the nutrients or heavy metals, in the inflow it shows the presence of these nutrients but in the outflow, it is zero,” he said.Who will address Bengaluru’s water woes? It’s estimated that as much as 98.5 percent of the city landscape will be concretised by 2025. Will a solution be in place by then? Only if the government acts quickly and adopts the right strategies.  IBTimes VideoRelated VideosMore videos Play VideoPauseMute0:01/1:26Loaded: 0%0:01Progress: 0%Stream TypeLIVE-1:25?Playback Rate1xChaptersChaptersDescriptionsdescriptions off, selectedSubtitlessubtitles settings, opens subtitles settings dialogsubtitles off, selectedAudio Trackdefault, selectedFullscreenThis is a modal window.Beginning of dialog window.

The project cost is around Rs 5,900 crore, according to the DPR. On top of it, nearly 52.5 sq km of forest land will be submerged if the controversial project goes ahead.The objective of Sharavati project was to bring the river water to Bengaluru from Linganamakki reservoir in Shivamogga district. But according to studies, the water retention in the catchment has come down and the dam there is silted. To make it worse, people living downstream Sharavati did not have water during the summer, raising questions if it was feasible to transfer water to Bengaluru. Yetinahole is a similar case and comes with a revised cost of Rs 13,000 crore. The authorities say it harnesses 24 TMC of water but in reality, only 9.85 TMC is available.Prof Ramachandra tells IBT Media that rejuvenation of lakes and propagation of water harvesting are the more efficient ways to conserve water than implementing big-budget projects. However, even when many of these government projects are failing and public money is wasted, not many seem to be questioning the wrong policies. “The most efficient way to conserve water is to rejuvenate the lake and retain the rainwater. If the lakes in Bellandur and Varthur region are desilted 5.4 TMC of water can be stored in the region. But the BDA has an objection against removing the silt as they said that only 20 per cent will be desilted,” said Prof Ramachandra.The BWSSB secondary treatment plant cannot remove the nutrients or heavy metals, in the inflow it shows the presence of these nutrients but in the outflow, it is zero The largest water body & the most polluted lake in Karnatakalast_img read more

Indonesia Airline plagued by safety concerns

first_imgA worker assists his colleague as an turbine engine of Lion Air flight JT610 is lifted up at Tanjung Priok port in Jakarta. Photo: ReutersIn April 2013, a Lion Air Boeing 737 missed the runway on the Indonesian resort island of Bali in bad weather and ploughed into the sea, cracking its fuselage open on the rocks.All 108 on board survived. But a September 2014 report by Indonesia’s air crash investigators highlighted errors and poor training, saying the 24-year-old co-pilot had failed to adhere to the “basic principles of jet aircraft flying.”Lion Air, struggling to get off a European Union blacklist because of “unaddressed safety concerns,” asked Airbus, which supplies part of its fleet, to help improve training.The EU removed the privately owned budget airline from the list in 2016 after it determined Lion Air met international safety standards. None of Indonesia’s roughly 100 airlines – most of them tiny – remain on the EU blacklist, with the last few coming off in June. All were banned in 2007; the national carrier, Garuda Indonesia, was the first to be removed in 2009.The crash of a Lion Air jet on Oct. 29 into the sea off Jakarta has put a spotlight back on the airline’s safety record, although the cause remains undetermined. None of the aircraft’s 189 passengers and crew survived.Lion Air’s latest crisis illustrates the challenge relatively new carriers face as they try to keep pace with unstoppable demand for air travel in developing nations while striving for standards that mature markets took decades to reach.Retired air force chief of staff Chappy Hakim, an adviser to the transport ministry, told Reuters he avoided flying with Lion Air or other Indonesian airlines, with the exception of Garuda, which has not had a fatal crash since 2007.“I know Garuda,” he said of the national carrier. “The other airlines, I don’t believe they do the maintenance and training properly.” He declined to elaborate further.Lion Air Managing Director Daniel Putut disputed any laxity in the airline’s safety culture, stressing that it conducted maintenance in accordance with manufacturer guidelines.The Directorate General of Civil Aviation, the Indonesian aviation authority, did not respond to multiple requests for comment about Lion Air’s safety record.Putut, a former pilot, also told Reuters during a visit to the airline’s training centre near the Jakarta airport that it complied with all regulatory requirements.He said Lion Air had worked hard to install an attitude of “zero tolerance” for accidents after the Bali crash, making last week’s disaster a painful eye-opener. Thousands of Lion Air flights have taken off and landed without serious incident since then.“We are also looking into what went wrong – new aircraft, experienced crews, and we have applied the zero-tolerance culture, yet another accident happened,” Putut said. “But we still don’t know the cause, so we will wait for the investigation from NTSC (National Transportation Safety Committee).”SAFETY CULTUREFrank Caron, head of a risk consulting firm who served as Lion Air’s safety manager from 2009 to 2011 after insurance companies requested a foreign expert, said that at the time he was troubled by what he regarded as the airline’s attitude that accidents were inevitable.“Safety is much more than running concepts and procedures,” he said. “Safety is a spirit, a state of mind, a way of thinking, an attitude in the daily aspects of an operational life. And that is precisely what Lion never got. They would say, ‘The airline has 250 flights a day, it is not abnormal that you have accidents.’”For example, after the 2013 Bali crash, Lion Air co-founder Rusdi Kirana told local media who asked about the airline’s safety record: “If we are seen to have many accidents, it’s because of our frequency of flights.”Caron claimed he left Lion Air after some of his safety recommendations were not implemented. Lion Air’s chief executive declined to comment on Caron’s account of his departure or his other assertions.Indonesian accident investigators made four recommendations after the Bali crash, including that Lion Air should “ensure that all pilots must be competent in hand flying” and teach proper cockpit coordination.They also urged the aviation authority to ensure all airlines under its control did the same.Putut said Lion Air embraced those recommendations.Between the Bali crash and the one last week, Lion Air had three non-fatal accidents, including one in April in which a 737 skidded off a runway, according to Flight Safety Foundation’s Aviation Safety Network database.Since it began operating 18 years ago, Lion Air has seen a total of eight planes damaged beyond repair in accidents, two of which killed a combined 214 people, according to the Aviation Safety Network database.During the same period, five jets from its chief rival, the national carrier Garuda Indonesia, were damaged beyond repair, and two accidents killed a combined 22 people, according to the database. Garuda declined to comment about its safety record.Since the 2013 Bali crash, Lion Air has sought to improve safety by gaining European Aviation Safety Agency (EASA) certification for its pilot training and maintenance facilities.EASA certifies its training centre to instruct other airlines’ pilots on A320 simulators and is seeking the same approvals for 737 jets and ATR72 turboprops, said Audy L Punuh, Lion Air’s Angkasa Pilot Training Organisation Director.RAPID GROWTHLion Air has expanded quickly since it started flying in 2000, overtaking national carrier Garuda by capturing more than half of the domestic market and establishing offshoots in Thailand and Malaysia.It has ridden a wave of aviation growth in Indonesia, where air travel has become critical for the economy.Domestic air traffic more than tripled in Indonesia over the past decade as prosperity and low fares made flying affordable for more people.With 129 million passengers in 2017, the Southeast Asian country was already the world’s 10th-largest aviation market and is projected to continue growing.That growth has been accompanied by an air-accident rate that was twice the global average in 2017 and consistently higher than Indonesia’s neighbours in the Association of Southeast Asian Nations, according to the United Nations’ aviation agency.Indonesian pilots are allowed to fly a maximum of 110 hours a month, which is more than the 100 hours in most other countries.Last year seven commercial planes were damaged beyond repair around the world, according to Boeing data; two were in Indonesia, wrecked in non-fatal accidents involving Sriwijaya Air and Tri M.G. Airlines.LATEST CRASHFlight JT610 took off from Jakarta at 6:20 a.m. on Oct. 29, bound for Bangka island, off Sumatra, and plunged into the sea 13 minutes later. Just before the crash, the pilot asked to return to the airport.The aircraft flew erratically on its previous flight and its airspeed readings were unreliable, according to an accident investigator and a flight tracking website.Investigators on Monday said the flight data recorder from the downed jet showed an airspeed indicator had been damaged during its final four flights, raising questions about maintenance and mechanical problems.Boeing said on Wednesday it had issued a bulletin to airlines reminding pilots about what it described as existing procedures for handling erroneous data from sensors.The Federal Aviation Administration later issued a directive calling for revisions to “operating procedures of the airplane flight manual.”It is too early for regulators to decide whether to reconsider the decision to remove Lion Air from the EU blacklist, EU Ambassador to Indonesia Vincent Guerend told Reuters.“The European Commission continues to monitor the situation on a regular basis,” he said. “It is still too early to have any conclusive views on the causes of the accident.”last_img read more

Study explains why soggy skin gets wrinkly but does not dissolve

first_imgImage credit: Wikipedia. Eczema treatment creams could make it worse Citation: Study explains why soggy skin gets wrinkly but does not dissolve (2011, March 10) retrieved 18 August 2019 from https://phys.org/news/2011-03-soggy-skin-wrinkly-dissolve.html Myfanwy Evans, a mathematician at the Research School of Physics and Engineering at the Australian National University in Canberra, and her colleagues developed a stringy skin model to try to explain how the network of keratin fibers in the skin is arranged. Keratin is a fibrous protein also found in the nails and hair. Scientists already knew the keratin networks were important, but until now no one was certain of their structure.After a period in water the outer layer of the skin (the stratum corneum) expands, producing prune-like wrinkles. Earlier researchers suggested the stratum corneum expands as it absorbs water, but no one had yet explained why skin doesn’t fall apart when it has expanded.Keratin is known to prevent evaporation from the skin and to absorb water to help keep the skin hydrated. The stratum corneum layer also gives the skin its stretchy properties and the ability to spring back.Using computer modeling Evans approached the question from a geometric point of view to try to explain why skin maintains its structural rigidity after long exposure to water. She said the outer layer of skin contains a three-dimensional pattern of keratin fibers woven together to form a structure capable of acting like a sponge. The fibers are helical when dry but straighten out as water is absorbed, which allows the network to hold a greater volume of water. All the contacts between the keratin fibers remain intact throughout the expansion, and this makes the material structurally stable, Evans said.Evans, who has just completed her PhD, said after 24 hours submerged in water, the skin can suffer irreversible damage.Evans specializes in the study of gyroids, which are mathematical shapes first described by a NASA scientist, Alan Schoen in 1970. Since then, gyroids have been found in nature, such as in some butterflies, where light refracted through crystalline gyroids in the wings produce the vivid colors.Evans said an understanding of the geometry behind why skin wrinkles after too long in the bath could help scientists design materials with the properties of skin, able to stretch without losing strength. The paper will be published in the cross-disciplinary publication, the Journal of the Royal Society Interface. © 2010 PhysOrg.comcenter_img Explore further (PhysOrg.com) — A new study by mathematicians in Australia has explained how skin remains stable in water and does not dissolve, and why it wrinkles and remains a strong barrier even after absorbing large quantities of water.

Research team claims to have directly sampled electricfield vacuum fluctuations

first_img © 2015 Phys.org Scientists ‘squeeze’ light one particle at a time Theoretical physicists believe that empty space is not empty at all, instead it is filled with quantum particles that pop in and out of existence creating what are known as electric-field vacuum fluctuations. Prior research has led to efforts that have measured such fluctuations indirectly, but no one, until now, has claimed to be able to measure them directly.The experiment conducted by the team in Germany involved using a long pulse of light to study a shorter pulse of light by firing both through a crystal at the same time. The long pulse had a horizontal polarization while the shorter pulse had a vertical polarization. In such an arrangement, properties of the crystal are dependent on the electric field that exists inside of it, which in turn causes a change in the polarization of the beams that are fired into it and then emerge on the other side. The researchers adjusted the timing of the light pulses to map out fluctuations in the electric field. To offset vacuum fluctuations related to their own existence, they put in just the probe pulse—nothing else. When repeated many times, the researchers found the polarization varied slightly, which the researchers attributed to vacuum fluctuations. To be able to actually see what was going on, the team varied the width and duration of the pulses but not the number of photons in a given beam. They noted that the shot noise should have stayed constant as the pulse grew in size, but it did not, which the team claims was due to electric-field vacuum fluctuations.Not everyone is convinced—many in the field on reading the paper by the team were quick to point out that variations in the pulse could just as easily have come from something else. Clearly more work will have to be done before the claims made by the team are accepted by the physics community.

The content is provided for information purposes only. More information: “Direct Sampling of Electric-Field Vacuum Fluctuations.” Science. DOI: 10.1126/science.aac9788ABSTRACTThe ground state of quantum systems is characterized by zero-point motion. Those vacuum fluctuations are generally deemed an elusive phenomenon that manifests itself only indirectly. Here, we report direct detection of the vacuum fluctuations of electromagnetic radiation in free space. The ground-state electric field variance is found to be inversely proportional to the four-dimensional space-time volume sampled electro-optically with tightly focused few-femtosecond laser pulses. Sub-cycle temporal readout and nonlinear coupling far from resonance provide signals from purely virtual photons without amplification. Our findings enable an extreme time-domain approach to quantum physics with nondestructive access to the quantum state of light. Operating at multi-terahertz frequencies, such techniques might also allow time-resolved studies of intrinsic fluctuations of elementary excitations in condensed matter.Press release (Phys.org)—A team of researchers working at the University of Konstanz, in Germany is claiming to have directly sampled electric-field vacuum fluctuations, which would be the first ever made. In their paper published in the journal Science, the team describes an experiment they carried out and a part of it which they claim indicates that they have measured vacuum fluctuations directly for the first time.last_img read more
