Humorously written review from Telegraph Yaris affordability comes at a price and another same source Fiats Retro Return By NICK BUNKLEY (NYT) A remake of the postwar Fiat will have to get Americans to forget the low quality of its first incarnation on these shores. So far, its working. The Trouble With Work Several articles of interest - NYT Sunday Review Opinion: The Limping Middle Class Robert Reich Op-Ed NYT on economics, jobs etc. The middle class doesnt have enough purchasing power to keep the economy going without sinking deeply into debt Do Happier People Work Harder? Opinion from Amabile & Kramer One Path to Better Jobs: More Density in Cities Population density, innovation and Vietnamese restaurants, relationship to jobs, housing costs etc., Ryan Avent And from the NYT Business Section Want to Lead? Ask Tennyson and Shakespeare Corner Office: Enrique Salem By ADAM BRYANT To convey management lessons, Enrique Salem, the president and chief of Symantec, sometimes turns to the words of classic literature. Before Wal-Mart, There Was A.& P. Off the Shelf By NANCY F. KOEHN In a new book, Marc Levinson tells of A.& P.s swift expansion in the early 20th century, and the powerful backlash it engendered. The tale offers parallels to retail battles of today. There is some great information in this very brief review available much faster than buying the book In Reversal, China Tries to Tamp Down Car Sales By KEITH BRADSHER NYT 5:20 PM ET Officials called for the countrys automakers to produce fewer but more technologically advanced cars. Add Sept. 6, 2011 Bob Lutz Returns To General Motors As Adviser. The AP (9/2) reported, "General Motors Co. has hired the ultimate car guy out of retirement to advise its senior leadership. Bob Lutz, 79, a former GM vice chairman for product development, left the company last year, but never really ended his 47-year career in the auto business." The Detroit Free Press (9/3, Thompson) reported that Lutz "retired in spring 2010, but has provided informal advice to GM executives for free ever since. He met about monthly with CEO Dan Akerson, who wanted to formalize the relationship and compensate him, Lutz told the Free Press" last week. "But that idea displeased GM's part-owner, the US government." China Withholding Subsidies For Volt Unless GM Shares Engineering Secrets. On the front of its business page, the New York Times (9/6, Bradsher, B1, Subscription Publication) reports "the new Chevrolet Volt plug-in hybrid" is meeting with resistance from Chinese officials, who are "refusing to let the Volt qualify for subsidies totaling up to $19,300 a car unless GM agrees to transfer the engineering secrets for one of the Volt's three main technologies to a joint venture in China with a Chinese automaker, GM officials said." Although there is no price on the Volt yet for China, "Chinese subsidies are nearly half the Volt's suggested retail price in the United States of $41,000, before including a tax break of up to $7,500 that Washington offers. Toyota May Produce Hybrid Parts In China. The Wall Street Journal (9/5, Shirouzu, Subscription Publication) reported that Toyota Motor may move production of key components used to make hybrids and other alternative-energy vehicles to China. BBC News (9/5) reported, "While boosting sales and capturing a larger share of the world's biggest car market is one of the main reasons behind Toyota's decision, analysts said other factors may have played a big role as well. China's restrictions on exports of rare earth elements is one of those factors." Also, the company's "operations were affected badly by the earthquake and tsunami that hit Japan earlier this year. Disruptions to the country's infrastructure and supply chain saw Toyota suspending or halting production not only at its Japanese factories but also at its overseas units." Analysts said the automaker "is now trying to ensure that it diversifies its production to avoid any such issues in the future." Spirit Aerosystems Says It Can Supply Necessary 737 Fuselages. 60/month !!! The Puget Sound Business Journal (9/3, Wilhelm, Subscription Publication) reported, "Boeing's decision to upgrade the current 737NG into the re-engined 737 MAX raises this question: will Spirit Aerosystems in Wichita be to able supply enough fuselages?" Spirit Aerosystems said it could match Boeing's plans of possibly 60 planes per month. Spirit spokesperson Ken Evans said, "Regarding 737, we've working very closely with them (Boeing) on re-engine. We see it as a positive opportunity to continue as a key supplier." Automated Defibrillators Often Fail, Researchers Say. Rather poor reliability MedPage Today (9/2, Walsh) reports that a research paper appearing online in the Annals of Emergency Medicine finds that the FDA "has received more than 1,000 reports over 15 years of deaths following failure of automated external defibrillators, a retrospective analysis showed. In 37 of the events, the defibrillator failed to even power on, and in 22% of the cases the device was unable to complete the heart rhythm analysis, according to Lawrence A. DeLuca Jr., MD, of the University of Arizona in Tucson, and colleagues." The most common failure, accounting for 45%, was when the defibrillator failed to deliver a shock recommended after rhythm analysis. Since in those cases a backup device was often successful when the primary defibrillator failed, the researchers recommended that public access programs provide backup units when possible. Shortage Of Engineering Students Threatens US's Role As World's Leading Innovator, Intel CEO And President Writes. Should be lots of opportunities In an op-ed in the Atlanta Journal-Constitution (9/3), Paul Otellini, president and chief executive of Intel Corp. and is a member of the President's Council on Jobs and Competitiveness, wrote, "Over the past 20 years, the percentage of engineers graduating in the United States has stagnated, while India and China surpass us with rapid progress." According to the American Society for Engineering Education, "forty percent of students enrolled in science, technology, engineering and mathematics leave their program after the first year." Experts Question Value Of Classroom Technology. Who knows, dont ask the customer! The New York Times (9/4, Richtel, Subscription Publication) profiles a Chandler, Arizona, school with a "technology-centric classroom," noting that the "class, and the Kyrene School District as a whole, offer what some see as a utopian vision of education's future. Classrooms are decked out with laptops, big interactive screens and software that drills students on every basic subject." However, despite strong enthusiasm, "since 2005, scores in reading and math have stagnated in Kyrene, even as statewide scores have risen." The Times paints this district as a thumbnail of observations from education experts that "schools are spending billions on technology, even as they cut budgets and lay off teachers, with little proof that this approach is improving basic learning." PRESIDENTS COUNCIL ON JOBS AND COMPETITIVENESS HOLDS LISTENING AND ACTION SESSION ON THE NEED FOR MORE U.S. ENGINEERS On August 31st, U.S. Secretary of Energy Steven Chu and Intel CEO Paul Otellini joined with business leaders and the Deans of Engineering schools in Portland, Oregon to discuss the need for more U.S. engineers as part of a regional Listening and Action session. For America to stay competitive in the global market, we must train and retain the worlds best engineers, said U.S. Secretary of Energy Steven Chu. Working together, private industry and the public sector can position the U.S. to continue to lead in science and innovation in the 21st century, creating good jobs and laying the foundation for a robust economy. Looking forward, this nation is at risk of a significant shortfall of qualified experts in science and math to meet the countrys needs, said Intel President and CEO Paul Otellini. Todays announcement is about inspiring and encouraging our next generation of engineers. Its a private sector commitment working arm and arm with the government to accelerate the specialized skills needed for America to retain its technological pre-eminence. These commitments support the Job and Competitiveness Councils goal to graduate 10,000 more engineering students from U.S. colleges and universities each year.
