24 October 2008From a concert in New York by world renowned cellist Yo-Yo Ma to a tree-planting ceremony in strife-torn Darfur to a blood donation drive in Namibia, celebrations were held across the globe today to commemorate the 63rd anniversary of the founding of the United Nations. To mark United Nations Day, virtuoso cellist and UN Messenger of Peace Yo-Yo Ma performed tonight with the Silk Road Ensemble in the annual UN Day Concert in New York. “This is a very special way to celebrate the day that the Charter of the United Nations came into force,” General Assembly President Miguel D’Escoto told those gathered for the concert.“He is a man who, through his wonderful music, is able to convey to us the values of the United Nations and inspire our commitment to them. Compassion, cooperation and communication, strength through diversity – these are some of the values that seem to be absent or inconsequential in international relations, yet these values should underpin all the undertakings of our great Organization.”Also in New York, UN staff and senior officials visited schools across the city to provide an overview of the Organization’s work, share their own experiences and interact with students in a campaign called UN4U, orchestrated by the Department of Public Information (DPI). Some 3,500 students heard from UN officials such as Under-Secretary-General for Communications and Public Information Kiyo Akasaka; the Secretary-General’s Special Representative for Children and Armed Conflict, Radhika Coomaraswamy; Executive Director of the Capital Master Plan Michael Adlerstein; and the Special Adviser on Gender Issues and Advancement of Women, Rachel Mayanja.The UN has also launched a newly redesigned website (unic.un.org) that serves as a portal to the network of 63 UN Information Centres (UNICs) around the world, whose efforts are crucial to telling the UN story to people in their own languages.Among the many events held worldwide was a ceremony in Moscow to mark UN Day as well as the 60th anniversary of the UN presence in that country. In a message to the event, Mr. Ban noted that &#822060 years on, our world and our Organization have changed beyond recognition. The problems we face have grown much more complex, impacting all of us around the globe.” In Addis Ababa, the celebration at the Economic Commission for Africa marks not only UN Day, but also the 50th anniversary of the Commission. It includes the launching of the ECA Jubilee Book, which chronicles the Commission’s main contributions to African development over the past five decades.Meanwhile, week-long events in Colombia include a seminar by the UN refugee agency for refugees, a forum on avian influenza, and a photographic exhibition on UN activities in the South American country. In Windhoek, Namibia, UN staff participated in a blood drive, organized in part by the World Heath Organization (WHO).The joint UN-African Union peacekeeping force in the Sudanese region of Darfur – known as UNAMID – marked the Day with a tree-planting ceremony, as well as music and dance, while the UN Interim Force in Lebanon (UNIFIL) honoured Lebanese staff who have served with the mission for more than 25 years. In Haiti, there was no celebration of UN Day as the occasion comes at a very difficult time for the island, as noted by the Secretary-General’s Special Representative for the country, Hédi Annabi.Mr. Annabi said that Haiti has suffered a crushing loss of lives and property during this year’s hurricane season, with the overall material damage estimated at over $1 billion by the World Bank. All efforts are now geared toward finding urgent humanitarian assistance for millions of suffering Haitians.The Special Representative urged UN staff in the country to take part in conferences, television and radio programmes and other public forums to advocate for greater humanitarian assistance to Haiti.In a related development, UN Emergency Relief Coordinator John Holmes, who today wrapped up a two-day visit to Haiti, expressed his willingness to make an additional allocation from the Central Emergency Response Fund (CERF) to fund the urgent humanitarian needs of people affected by the recent hurricanes.UN Day has been celebrated on 24 October every year since 1948, exactly three years after the UN Charter entered into force. In 1971, the General Assembly adopted a resolution recommending that the Day be observed as a public holiday by Member States. read more

The Toronto stock market was lower Tuesday amid relief that there was a clear-cut winner from Tuesday’s U.S. presidential election, with Barrack Obama winning a solid majority of electoral college votes over Republican challenger Mitt Romney.But that sentiment was tempered by the realization that there will likely be some tough slogging ahead as Democrats and Republicans try to extricate the government from automatically imposing tax hikes and steep spending cuts at the end of the year.Investors worry this so-called fiscal cliff scenario would send the U.S. back into recession.The S&P/TSX composite index fell 82.91 points to 12,278.29 as Canadian investors also absorbed earnings reports from the resource and industrial sectors — with several heavyweights missing estimates. The TSX Venture Exchange was 4.34 points lower to 1,298.8.The Canadian dollar was down 0.16 of a cent to 100.67 cents US as commodities backtracked and traders took in another reminder of the fragile state of Europe’s economy while looking ahead to a crucial vote in the Greek parliament later in the day.New York markets were deep in the red as the Dow Jones industrials tumbled 174.56 points to 13,071.12, the Nasdaq composite index dropped 37.94 points to 2,973.99 while the S&P 500 index fell 19.21 points to 1,409.18.There had been concern that America would have to endure a re-run of the protracted election of 2000.But its arms of government remain divided, with the Democrats holding onto their majority in the Senate and the Republicans in control of the House of Representatives. That could still lead to a logjam in policymaking, not least over the state of the country’s public finances.“In other words, it’s like nothing ever happened,” observed Andrew Pyle, investment adviser at ScotiaMcLeod in Peterborough, Ont.“And that may not be great news for the markets, especially as there are no concrete signs that either Republicans or Democrats are any more willing to reach across the isle and compromise on the key components to real sustainable fiscal reform.”Greece was also back in focus ahead of a crucial vote in its parliament later in the day that could determine whether the country stays in the eurozone. If lawmakers don’t back a C13.5 billion package of spending cuts and tax increases, the country faces the prospect of losing access to its bailout lifeline and potentially defaulting on its mountain of debt and leaving the monetary union.The European Union has also downgraded its economic forecasts for the 27-country bloc. The EU’s executive arm says it now expects the region’s gross domestic product to contract by 0.3 per cent on an annual basis this year, rather than remaining flat as it predicted in the spring. It also said that the 17 countries that use the euro will contract, with GDP falling 0.4 per cent, against a previous expectation of a 0.3 per cent fall.Commodity prices turned lower following sharp gains on Tuesday.The base metals sector led losers, down two per cent as December copper shed five cents to US$3.46 a pound. Teck Resources (TSX:TCK.B) declined $1.06 to $32.46.The energy sector fell 1.3 per cent as the December crude contract on the New York Mercantile Exchange lost $2.04 to US$86.67 a barrel after gaining $3 Tuesday. Canadian Natural Resources (TSX:CNQ) lost 58 cents to $29.62.The industrials sector was also a weight as transport giant Bombardier Inc.’s (TSX:BBD.B) net income rose to US$212 million or 12 cents a share in the third quarter. But its revenues slipped to US$4.3 billion, down about $300 million from the third quarter of 2011, lighter than analysts had expected as weakness at its rail equipment division continued and its shares fell 13 cents to $3.48.Elsewhere in the component, WestJet (TSX:WJA) shares gained 40 cents to $18.36 as profits soared almost 80 per cent in the third quarter to $70.6 million or 52 cents per diluted share, up from $39.3 million or 28 cents per share a year ago. Revenue rose to $866.5 million from $755.3 million.The financials sector was also a weight as Manulife Financial (TSX:MFC) gave back 22 cents to $12.30.The gold sector was the sole advancer, up 0.85 per cent while December bullion was off $7.60 to US$1,722.60 an ounce. Goldcorp Inc. (TSX:G) rose 54 cents to $44.28. Franco-Nevada Corporation (TSX:FNV) turned a profit of US$52 million, or 36 cents per share in its third quarter. Revenue fell to $105.2 million from $113.3. Earnings on an adjusted basis rose to $45.3 million, or 31 cents per share, beating expectations by three cents. The mining financier also raised its monthly dividend by 20 per cent to six cents per share and its shares rose $1.65 to $57.70.Meanwhile, pipeline company Enbridge Inc. (TSX:ENB) posted net profit of $189 million or 24 cents per share, compared with a small net loss of $5 million or one cent a share last year. Adjusted earnings rose to $269 million or 34 cents per share, a penny below analyst estimates. Enbridge’s total revenue was $5.79 billion, down from $6.28 billion a year earlier. Its shares slipped 19 cents to $39.90.Agrium Inc. (TSX:AGU) reported it had $129 million or 80 cents per share in net income, down from $293 million or $1.85 per share a year earlier. Ex-items, the Calgary-based fertilizer company’s net income would have been $215 million or $1.34 per share, well below a consensus analyst estimate of $1.76 per share and its shares gave back $7.58 or 7.1 per cent to $98.82.In the U.S., Kraft Foods’ net income rose 13 per cent in the third quarter to US$470 million, or 79 cents per share, 10 cents above estimates. Revenue rose three per cent to $4.6 billion.European bourses headed lower in the wake of the latest grim economic news as London’s FTSE 100 index lost 0.49 per cent, Frankfurt’s DAX was down 1.23 per cent and the Paris CAC 40 shed 1.02 per cent. read more

“What we are seeing now is a huge process of urbanization in the south which goes hand in hand with development. You cannot have one without the other. The problem is that the institutional architecture cannot keep pace with urbanization,” said the Executive Director of UN-Habitat, Joan Clos at the opening of the 6th World Urban Forum in Naples, Italy.“If there is no proper anticipation urbanization becomes a mess and if you try to correct the problem afterwards it costs a lot to fix. Countries are overwhelmed by urbanization. It’s like a tsunami. Urbanization goes faster than the capacity to manage it,” Mr. Clos said. “We need to re-design our cities to face these challenges.”Mr. Clos stressed the importance of urban planning at national, state, and local levels to avoid informal settlements and slums, as well as high concentrations of people in mega capitals.He stated that planning policies would help countries provide their citizens with jobs and prosperity while still tackling environmental challenges.The World Urban Forum was established by the United Nations to examine one of the most pressing problems facing the world today: rapid urbanization and its impact on communities, cities, economies, climate change and policies. Organized jointly by UN-Habitat, the Government of Italy, the Campania Region and the city of Naples, the theme for this year’s meeting, which will be attended by more than 3,000 participants, is The Urban Future. read more

“Bureaucratic obstructions on the delivery of assistance must stop. We don’t have the time for arbitrary restrictions on how and to whom we are allowed to deliver aid,” Assistant Secretary-General for Humanitarian Affairs, Kyung-wha Kang, told Security Council members in a closed-door session.Through a resolution adopted in February, the Council demanded “that all parties, in particular the Syrian authorities, promptly allow rapid, safe and unhindered humanitarian access for UN humanitarian agencies and their implementing partners, including across conflict lines and across borders.”The Council also insisted that all parties cease attacking civilians, including through the indiscriminate use of weapons in populated areas, such as shelling and aerial bombardment with barrel bombs, whose use has been condemned by the UN.Today, Ms. Kang, who is also the Deputy Eme4rgency Relief Coordinator, noted with deep regret that “violence continues relentlessly” as do “flagrant violations of international humanitarian law and human rights by all parties.” Women, children and men are being killed and maimed, and an estimated 2.5 million population in need of urgent humanitarian assistance.“We once again appeal for rapid, unhindered and safe access to every Syrian in need,” Ms. Kang told the Council. “All delivery routes must be made available to us – both cross-line and cross-border. Medical and surgical supplies urgently need to reach the wounded and sick.”She added that UN agencies and partners are doing everything possible to address mounting needs “but the solution to this crisis does not lie with us.”Under-Secretary-General Valerie Amos is expected to brief the media early next week on the situation in Syria, according to her office (OCHA). read more

first_imgMs Petrova said she thinks it is “unlikely” that it was the Russian Secret Services who were behind the attack, explaining: “They lived in moderation, Yulia posted all sorts of photos … she posted photos with papa, if she would have feared something she wouldn’t haven’t posted.”However, the old friend of Skripal, who has known her for decades, admitted the young woman was an “ice queen” and would be unlikely to speak of any threats. She said there “there should be video” of the attack, and that it was strange there was limited information or pictures from the street where it happened, explaining that in Moscow there is CCTV on most of the streets. She said: “No she didn’t express (fear), but she was closed, ice queen even, if she was worried she was worried inside herself , I found out that her mom died and asked, she said yes, she was very restrained, I asked about dad, she said he’s great, he’s working.”If her papa was a spy by specialty, Yulia was closed off … she always smiled, she never told anyone about her problems, never looked worried, maybe she did have problems but we didn’t know about this. … she never said anything extra, she never shared problems, she was light, just smiled, didn’t talk about problems, she was like Americans and Brits, not typical Russian.”Sergei Skripal and his daughter Yulia remain in critical condition in Salisbury District Hospital after being attacked with potent Russian nerve agent Novichok.  Friends of Yulia Skripal have accused the British Government of covering up her “death”, as they say they doubt she is still alive.Yulia Ni, who is listed as one of the poisoned 33-year-old’s five best friends on the popular Russian social networking site VK, said: “I need some undeniable proof that she is actually alive, because we have suspicions that the truth about Yulia’s and her father’s conditions are being held from us.”She said that friends back in Russia were desperate for further details about Ms Skripal’s condition, and found the scarce information offered by the British government suspicious.Ms Ni told The Telegraph: “It appears to be very strange that there is not more concrete information available. The week has passed since they went into a comatose state.”Can they breathe on their own or are they on a respirator? Do they react to light or have any other basic reflexes? The authorities should have already released some information to the public!” A childhood friend of Ms Skripal, Irina Petrova, told The Telegraph she was suspicious of the police investigation into her friend’s poisoning.

first_imgTesla’s Model X can haul 7 adults for about 300 miles without breaking a sweat. Hold my beer, says Proterra. Their all-electric bus has room for a driver and 40 passengers and they just drove one 1100 miles on a single charge.There’s an asterisk next to that impressive feat, namely that the Proterra E2 Max that recently broke the EV distance record didn’t have any passengers on board. Still… they drove a 15-ton bus pretty much the distance between New York and Minneapolis on one charge.That’s an impressive feat, and one that requires an equally impressive battery pack to pull off. The E2 Max sports a 660 kWh battery, which is more than six times the capacity of the Model X.As big as its battery pack is, the buses also recharge quickly thanks to another one of Proterra’s creations. Last year they unveiled a a 1400-amp rapid-charging system that can fully replenish the E2 Max’s cells in about an hour. Most consumer EVs on the road need at least 3 hours to recharge.The coolest thing about Proterra’s charger? That they’re totally cool with sharing the particulars of its design with other companies. CEO Ryan Popple says that keeping Proterra’s system locked down would be bad for their business “because it tends to slow down the adoption of new technology.”Proterra believes they’re poised to make a big splash in mass transit with the E2 Max. They note that its “low operational cost per mile compared to conventional fossil fuel powered buses” makes it a very attractive option. Even when it’s fully loaded, the E2 Max won’t have any trouble making the rounds in a major city. The average bus only logs somewhere between 100 and 200 miles, so range anxiety shouldn’t be an issue with this big, green behemoth.The E2 Max has other advantages, too. Proterra says that it has 30% fewer parts and requires 75% less brake maintenance, and, of course, no messy oil changes. Over the average life of a bus, The E2 Max costs nearly a quarter million dollars less to operate than a comparable diesel hybrid.last_img read more

The deployment, which will begin April 1, 2019 in support of aerial patrol operations on the Arizona/Mexico border, comes following a request for National Guard volunteers through the National Guard Bureau, according to a release from the Governor’s office.  This is the first deployment of the Alaska National Guard to support the current border security mission. Alaska’s support for this request is not expected to impact any scheduled local training, deployments or domestic operations commitments, including fire suppression operations. This deployment to the U.S. Southern border will be funded by the federal government. Governor Dunleavy: “Alaska stands ready in support of the President’s mission to secure the southern border. While this emergency may be thousands of miles away, we must be vigilant in our shared responsibility to address this crisis. I thank the numerous guardsman, and their families, for answering the call of duty and volunteering to serve in these important support roles.”last_img read more

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. The work demonstrated the atomic geometry of metallic quantum contacts that could be modulated with light and the ability to reverse switch (on/off, vice versa) their conductance using plasmonic heating. While the atom-by-atom separation of electrodes were clearly observed, they could also adjust the gap size, between the electrodes at sub-angstrom resolution by controlling the intensity of light. Zhang et al. showed that the plasmon can potentially breakthrough the diffraction limit of light to realize nanofocusing, to transfer the plasmon-controlled atomic switch to realize highly integrated nanodevices; opening a new path to engineer nanoelectronic devices. Explore further While generating a nanogap was crucial to fabricate single molecule-based devices, engineering an adjustable atomic-scale gap has remained a significant challenge. Although fixed gap sizes could not be adjusted post-fabrication, the gap-size could be readily and continuously adjusted through plasmonic heating at sub-angstrom resolution, as shown by Zhang and the research team. For this, they used a commercial light-emitting diode (LED) lamp as a light source in the experiments with an AC adaptor to continuously control the intensity of light. The experimental setup did not require special optical hardware or high power laser sources. They used a commercially available gold wire with a constriction in the middle on a spring steel substrate to construct the nano contacts. Then using a ‘mechanically controllable break junction’ (MCBJ), the scientists stretched the constriction by bending the substrate, and observed it with scanning electron microscopy (SEM) images. Thereafter, the scientists reduced the cross-section of the constriction to form two separate electrodes. When they turned the light on, the conductance increased and decreased when the light was turned off; the large conductance resulting from light illumination strongly reconnected the two separated electrodes.The scientists analyzed the phenomenon at the level of atomic arrangement, upon light illumination. They showed that the nanogaps had strong absorption of light in the visible and near infrared regions due to localized surface plasmon resonances (LSPR). When the frequency of the LED light matched the oscillation frequency of the free electrons and the electromagnetic field at the tip of the electrodes, the LSPR around the gap was excited. The absorbed light then converted to thermal energy causing nanoelectrode expansion and their reconnection. The conductance reached its maximum value when the system was at thermal equilibrium. When the light was shut off, the electrons separated once more. Characterization of MCBJ devices and simulation of expansion distribution of the electrodes upon light illumination. a) System for the measurement of optical spectroscopy. b) Measured dark field scattering spectra from the gap area that employs three different samples. The gap size is ~2 nm in sample A and ~0.2 nm in sample B. The electrodes were strongly reconnected, and no nanogap is observed in sample C. Plasmonic resonances are indicated by the arrows. c) Model used in the simulation. Parts of the large metal wire close to the nanotips were considered. The gap size between two nanotips is initially set to 2 nm. The polarization of the incident light is parallel to the x-axis. d) Expansion distribution (in X component) when equilibrium temperature was established. Credit: Light: Science & Applications, doi: 10.1038/s41377-019-0144-z. , Light: Science & Applications Zhang et al. also observed how the nanogap size could be precisely modulated by light by showing that the conductance could be modified in the tunneling region, between the gap of the two electrodes, by controlling the LED light. When the light intensity was fixed, they could keep the tunneling current constant for longer. The scientists estimated the distance between the two electrodes using the Simmons equation; used to describe the relationship between the tunneling current and the tunneling gap size. They could thereby precisely control the distance between the two separated electrodes at sub-angstrom accuracy using the light intensity.To confirm that the origin of switching behavior was plasmon-induced heating in the nanoscale plasmonic systems, the scientists investigated the scattering spectrum of the MCBJ samples to reveal the frequency of plasmonic resonance. The results indicated that the conductance change related to the expansion of the electrodes due to plasmonic heating. Zhang et al. also performed finite element method simulations to estimate the expansion of the electrodes and solved the electric field distribution, temperature distribution and thermal expansion on light illumination, using the COMSOL Multiphysics program package. The simulation calculated the maximum displacement of the electrodes as approximating 0.4 nm. Zhang et al. were able to further optimize the switching frequency by optimizing the characteristic dimensions for heat transfer. In this way, the scientists experimentally proved that atomic switches could be rapidly operated via plasmonic heating. Illumination system with different frequencies.

In the method developed by Zhang et al. light can be used to control electrical conductance at the junction between gold nano-electrodes by heating electrons at the electrode surface, in a technique known as ‘plasmonic heating.’ They validated the experimental mechanisms using simulations. The research team expanded electrodes via plasmonic heating to close the gap and turn the switch on, paving the way to build single-molecule transistors and nanopore-based biosensors at the nanoscale. Molecular junctions were previously investigated as an approach to build nanoswitches by employing photochromic (light sensitive) molecules that switched between two distinct isoforms. The present work by Zhang et al. contrastingly demonstrated conductance switch behavior only with a bare metallic contact, under light illumination, without any molecules. They demonstrated the conductance of bare metallic quantum contacts as reversible switches across eight orders of magnitude to substantially exceed the performance of the previous molecular switches. The scientists were able to adjust the gap size between the two electrodes after the switch process with sub-angstrom accuracy, by controlling the light intensity or polarization.

Atomic Switch: Atom/Ion Movement Controlled Devices for Beyond Von-Neumann Computers, Advanced Materials (2011). DOI: 10.1002/adma.201102597 Scientists have recently developed a light controlled nano-switch to lay groundwork for atomic device development in nanotechnology. They engineered the switches at the nanoscale in a first step toward fully integrated electronic device miniaturization. The multidisciplinary research was conducted by Weiqiang Zhang and co-workers, and an international team of collaborators. Results of the study are now published in Light: Science & Applications. Journal information: Nature To understand how conductance depended on the light intensity, the scientists performed experiments where the maximum light intensity within each illuminated circle gradually increased. Zhang et al. showed that the maximum conductance in each circle increased approximately linearly with the intensity of light. They obtained repeatable data of the current as a function of the light intensity and showed how the conductance of quantum contact, could be regulated by the intensity of light. In the present study, Zhang et al. used this principle to show how a metallic, atomic scale contact could be operated reliably as a conductance switch through controlled illumination of light. To engineer the metallic atomic-scale contact they precisely stretched a metal nanowire using the mechanically controllable break junction. When they reduced the cross-section of the metal wire to a few nanometers or a few atoms, the diameter became comparable to the Fermi wavelength of the electrons, allowing quantum-mechanical effects to strongly influence the properties of electron transport. Using these principles, Zhang et al. showed how the conductance of an atomic gold contact could be switched from a few quanta of conductance to hundreds of quanta, and vice versa with light illumination. The scientists were able to reversibly switch the metallic quantum contacts between the open and closed state by controlling the light intensity. They created a nanogap between the quantum contacts within which coherent tunneling governed electron transport. In-plane coherent control of plasmon resonances for plasmonic switching and encoding Citation: Atomic switches by plasmonic heating of metallic contact points (2019, April 3) retrieved 18 August 2019 from https://phys.org/news/2019-04-atomic-plasmonic-metallic-contact.html Engineering electronic devices using functional building blocks at the atomic scale is a major driving force in nanotechnology to form key elements in electronic circuits, which were previously miniaturized using mechanical tunneling, bias voltage/current operation and electrochemistry. Previous studies did not, however, address the concept of atomic switches controlled by plasmonic heating. Surface plasmons are coherent delocalized electron oscillations at the interface between two materials that form metallic nanostructures, which can be concentrated into the subwavelength gaps between the materials. In principle, when the resonance frequency of surface plasmons match the frequency of the incident light, the plasmon resonance is excited to produce strong light absorption and substantial plasmonic heating. last_img read more

first_img March 10, 2016 497 Views in Daily Dose, Government, Headlines, News CFPB Director: Mortgage Credit is “Still Too Tight, In My View” Consumer Financial Protection Bureau Mortgage Credit 2016-03-10 Staff Writercenter_img Consumer Financial Protection Bureau (CFPB) Director Richard Cordray called attention to the mortgage industry, particularly lenders, in a speech on Wednesday, where he highlighted some of the progress and pitfalls that the housing market faces.An Urban Institute report recently confirmed Cordray’s remarks by finding that between 2009 and 2014, 5.2 million borrowers with less-than-pristine credit were unable to get a mortgage loan due to tight lending.The data showed that between 2009 and 2013, 4 million loans could have been originated if credit standards were like 2001’s levels. On top of this total, an additional 1.2 million borrowers were unable to get a mortgage loan.”A tight credit box means that fewer families will become homeowners at an opportune point in the housing market cycle, depriving them of a critical wealth-building opportunity,” Urban Institute said. “It slows the housing market recovery by limiting the pool of potential borrowers. Ultimately, excessively tight credit hinders the economy, as it slows all the associated economic activity that comes with home buying, such as furniture purchases, landscaping, and renovations.”In his speech, Cordray stated that the millennial generation is beginning to welcome homeownership despite the stereotype surrounding this generation, but as they are facing with the issue of tightening credit.”Credit is still too tight, at least in my view, but we can now look in the rear-view mirror and see that some of the undue fears people had about legal liability under the QM rule, or market paralysis due to streamlining the mortgage disclosure forms, can be put in healthier perspective,” Cordray explained. “There is ample opportunity in the mortgage market as it continues to heal, and you should be doing what you do best: serving your customers through great deals and great customer service. Homeownership still remains the most effective engine of wealth accumulation for the American middle class, and you are the ones who are making that happen and rebuilding a key marketplace that failed this country so brutally less than a decade ago.”Despite the bleak credit picture, mortgage lending practices have improved since the financial crisis, Cordray said in his speech.”The market crash itself led to many changes, with bad actors and bad practices no longer feasible in a marketplace that had all-too-belatedly exposed the risks inherent in irresponsible and often predatory lending. Indeed, if anything, the market meltdown produced an overreaction, marked by very tight credit and historically low levels of consumer demand and available supply,” he said. “For those of us engaged in the important work of protecting consumers, these developments posed a very tricky task in implementing reforms. We were well aware of the concerns many had raised that the cost of protecting consumers would constrict the availability of credit and even drive many financial service providers out of business altogether.

first_img NEW YORK, N.Y. – Peggy Cummins, a Welsh-born stage and film actress who worked just a few years in Hollywood but left behind an indelible performance as the lethal, beret-wearing robber in the noir classic “Gun Crazy,” has died at age 92.Cummins, who retired from acting in the early 1960s, died Friday in London at age 92. Her friend Dee Kirkwood said she died of a stroke.A child star in England, Cummins was not yet 20 when brought to the United States in 1945 by studio boss Darryl F. Zanuck to play the title role in an adaptation of one of the decade’s raciest novels, “Forever Amber.” The petite blonde was passed over in favour of Linda Darnell, allegedly because she was too young, but Cummins was most certainly of age for “Gun Crazy,” which came out in 1950.Initially dismissed by The New York Times as “pretty cheap stuff,” the low-budget “Gun Crazy” was directed by Joseph H. Lewis and secretly co-written by the blacklisted Dalton Trumbo, who devised a tale of sex and violence and of love destroyed by greed.Cummins played Annie Laurie Starr, a sharpshooter in a travelling carnival who hooks up with a local marksman, Bart Tare, played by John Dall. Tare is an ex-reform school student who wants to go straight, but Starr shames (and seduces) him into a life of crime, telling him: “I want things, a lot of things, big things.” His reluctance to fire a gun is more than compensated by her willingness to kill anyone.“I told Peggy, ‘You’re a female dog in heat, and you want him. But don’t let him have it in a hurry. Keep him waiting,’” Lewis later explained.The film’s erotic energy and documentary style eventually made it a cult favourite, with admirers including the French New Wave directors Francois Truffaut and Jean-Luc Godard. In the mid-1960s, when writers David Newman and Robert Benton were trying to sell a synopsis for what became “Bonnie and Clyde,” Truffaut arranged a screening of “Gun Crazy” and suggested it as inspiration. In 1998, the Library of Congress selected “Gun Crazy” for preservation for being “culturally, historically, or esthetically significant.”Cummins made just a handful of American movies, including “Escape” and “The Late George Apley,” before returning to England in 1950. She did briefly date then-aspiring politician John F. Kennedy and was asked out by Howard Hughes, only to have the wealthy aviator crash his plane and cancel their dinner plans. Back in England, she married William Herbert Derek Dunnett and remained with him until his death in 2000. They had two children.Born Augusta Margaret Diane Fuller in Wales and raised in Dublin, she was the daughter of actress Margaret Cummins. By age 12, Peggy Cummins had starred in a stage production of “Alice in Wonderland” and by 15 had appeared in her first film, “Dr. O’Dowd.” The most notable of her later movies was the horror favourite “Night of the Demon” (also known as “Curse of the Demon”), directed by Jacques Tourneur and featuring Cummins as the niece of a psychologist whose investigation of a satanic cult leads to fatal consequences. Her final film, “In the Doghouse,” came out in 1962.In recent years, Cummins appeared at numerous retrospectives for “Gun Crazy,” calling it her favourite production, even though she insisted she was nothing like Annie. Cummins saw herself as a country girl, indifferent to possessions and happy to raise a family. But she did appreciate the chance to misbehave on the screen.“The tendency was then, that if you’re short and blonde and reasonably pretty, you always played rather pretty parts,” she said at a 2012 screening in Hollywood. “To tell you the truth, I always wanted to play all the Bette Davis parts.” by Hillel Italie, The Associated Press Posted Jan 2, 2018 10:18 am PDT Last Updated Jan 2, 2018 at 10:40 am PDT AddThis Sharing ButtonsShare to TwitterTwitterShare to FacebookFacebookShare to RedditRedditShare to 電子郵件Email Peggy Cummins, star of noir classic “Gun Crazy,” dead at 92last_img read more

first_imgThe series of navigational warnings (Navtex) issued by Turkey, by which it reserved swathes of Cyprus’ Exclusive Economic Zone (EEZ), are illegitimate and in any case they do not affect the island’s ongoing gas exploration programme, the government said on Thursday.Cyprus will press on with its energy plans regardless, government spokesman Nicos Christodoulides told reporters.“To us, these [Turkish] Navtex, these notices to mariners, do not exist. They have already been cancelled, and no one takes them into account or imparts any legitimacy to them.”The best response to the usual Turkish bravado in the eastern Mediterranean, he added, is the continuation of Cyprus’ gas exploration activities.“At the moment, there is in progress an important drill and we hope to have the results soon,” he said, referring to the ongoing exploratory drill by companies Total and ENI in offshore block 6.The results of the drill, which began in late December, are expected in early February.Asked whether the results might be announced between the first and second round of the presidential elections, Christodoulides said this was entirely up to the companies.The implication of the reporter’s question was that the Disy-led government might seek to score political points in the midst of the electoral process.“I cannot at this time be more specific as to the timeline, nor would it be responsible of me to comment on that,” Christodoulides responded.After concluding its operations in block 6, the drillship will almost immediately head to block 3 – also licensed to ENI – for another exploratory drill. The target in block 3 is codenamed ‘Soupia’ (cuttlefish).You May LikePopularEverythingColorado Mom Adopted Two Children, Months Later She Learned Who They Really ArePopularEverythingUndoLivestlyChip And Joanna’s $18M Mansion Is Perfect, But It’s The Backyard Everyone Is Talking AboutLivestlyUndoSmart Tips DailySeniors With No Life Insurance May Get A $250,000 Policy If They Do ThisSmart Tips DailyUndo Concern over falling tourism numbersUndoPensioner dies after crash on Paphos-Polis roadUndoCypriot tycoon launches ‘Bank of Cannabis’Undoby Taboolaby Taboolalast_img read more
