Dress in Blue Day to raise colon cancer awareness | VUMC ...

by Dagny Stuart | Posted on Thursday, Feb. 21, 2013 ? 9:13 AM

?Nashville Elvis? will be in the building at Vanderbilt University Medical Center and Vanderbilt Health One Hundred Oaks, Friday, March 1, to celebrate colon cancer awareness.

?We have invited the entertainer known as Nashville Elvis to our Dress in Blue Day celebration because one of Elvis? best-loved songs is ?Blue Suede Shoes,? and blue is the color associated with colon cancer,? said Sheila Bates, MSSW, community outreach manager for Vanderbilt-Ingram Cancer Center?s Office of Patient and Community Education.

?We?re encouraging everyone to wear something blue as a reminder that early screening may help detect or even prevent the disease.?

Bates said anyone old enough to remember Elvis is the right age to start thinking about colon cancer screening.

The Colon Cancer Alliance initiated Dress in Blue Day in 2009 to raise awareness about colorectal cancer which is the second leading cause of cancer-related death in the United States. Approximately 150,000 people are diagnosed with colorectal cancer every year and more than 51,000 die from the disease.

During the Dress in Blue Day event on March 1, Nashville Elvis will be in the Courtyard Caf? at lunchtime between 11 a.m. and 1 p.m., and in the lobby at Vanderbilt Health One Hundred Oaks from 2-4 p.m. Visitors to the cafeteria and One Hundred Oaks may have their pictures taken with Nashville Elvis, and with two VUMC employees who are dressed as giant colon polyps.

Polyps are small growths on the lining of the intestinal tract that may turn into cancer.
There will also be games and prizes for visitors who stop by the colorectal cancer education tables.

Everyone is advised to start screening beginning at age 50, and individuals who have a family history of the disease or persistent symptoms may need to start screening even earlier.

Screening with a test like a colonoscopy is the best way to prevent colorectal cancer. During the test a physician uses a long, flexible tube with a camera on the end to search for polyps inside the colon and can remove the polyps to prevent cancer from developing.

Obesity, cigarette smoking, a poor diet and lack of exercise all contribute to colon cancer risk.

The Vanderbilt Hereditary Colorectal Cancer Registry provides genetic counseling and testing for those who may have a hereditary risk. Contact Duveen.sturgeon@vanderbilt.edu or call 322-1590 for registry information. For more details about Dress in Blue Day, contact Sheila.bates@vanderbilt.edu or call 948-4130.

Simple view of gravity does not fully explain the distribution of stars in crowded clusters

Feb. 20, 2013 ? Gravity remains the dominant force on large astronomical scales, but when it comes to stars in young star clusters the dynamics in these crowded environments cannot be simply explained by the pull of gravity.

After analyzing Hubble Space Telescope images of star cluster NGC 1818 in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, researchers at the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University in Beijing found more binary star systems toward the periphery of cluster than in the center -- the opposite of what they expected. The surprising distribution of binaries is thought to result from complex interactions among stars within young clusters.

The team's finding will be published in the March 1 print issue of The Astrophysical Journal and is now online.

In the dynamic environment of a star cluster, high-mass stars are thought to gravitate toward the center of a cluster when they give a 'kick' to lower-mass stars and lose energy, explained KIAA Prof. Richard de Grijs, who led the study. This leads them to sink to the cluster center, while the lower-mass stars gain energy and might move to orbits at greater distances from the cluster core. Astronomers call this process "mass segregation."

However, when the Kavli researchers looked closely at binary star systems within NGC 1818, they found a much more complex picture.

Most stars in clusters actually form in pairs, called "binary stars," which initially are located so close to one another that they interact, resulting in the destruction of some binary systems. Other binaries, meanwhile, swap partners. Astronomers had expected that the same process that leads a cluster's most massive stars to gravitate toward the center would also apply to binaries. This is because together, the stars that make up binaries have more mass on average than a single star.

When the astronomers discovered that there were more binaries the farther from the core they observed, they were initially baffled by this unexpected result. They concluded that so-called "soft" binary systems, in which the two stars orbit each other at rather large distances, are destroyed due to close encounters with other stars near the cluster's center. Meanwhile, "hard" binaries, in which the two stars orbit one another at much shorter distances, survive close encounters with other stars much better, all throughout a cluster. This is why more binaries were seen farther out than close in.

Mapping the radial distribution of binary systems in dense star clusters had never been done before for clusters as young as NGC 1818, which is thought to be 15-30 million years old. This is difficult to do in any case, because there are no young clusters nearby in our own Milky Way galaxy. The new result provides new insights into theoretically predicted processes that govern the evolution of star clusters.

"The extremely dynamic interactions among stars in clusters complicates our understanding of gravity," team member Chengyuan Li said. "One needs to investigate the entire physical environment to fully understand what's happening in that environment. Things are usually more complex than they appear."

Mentoring Rising Tech Talent in Uganda's Capital - Core77

Posted by An Xiao Mina? | ?20 Feb 2013 ?|? Comments (0)

It's a busy, buzzing weekend at Mara LaunchPad. Nigel Ball, the director of Mara, is circulating amongst the crowd, as are a half dozen mentors, including myself. It's a scene that would be familiar to any tech observer in New York or San Francisco... but this isn't either city. In fact, it's not even in North America: The first weekend-long Mara Business Hackathon has just begun in Kampala, Uganda.

Mara LaunchPad, operating under the social business Mara Foundation, is one of Kampala's premiere business incubators. Along with other tech-oriented spaces like Hive Colab and the Outbox Hub, Mara offers office space, mentorship and even venture capital to new startups in Uganda. Many of these businesses often focus on new technologies.

What made this hackathon different from many of the popular tech events in Kampala was its focus on building a business. Yes, a prototype and good design were key, but what was more important was that teams developed a solid business model and financials?not an easy feat at all, given the dire need for reliable data in the country.

"In 48 hours our idea matured in away that would [normally] have taken us weeks or months," noted Ivan Mworozi. "The access to experts from various fields was invaluable." Indeed, Mworozi cited the mentorship as key. He delivered the hackathon's winning pitch for E-ride, a new service he and four others will be developing to facilitate transportation in the traffic-clogged city.

Observing that an informal system of car sharing already exists, they wanted to streamline that method using mobile technologies: "Lot of cars and trucks were moving around practically empty because they had no way of know[ing] that we were looking for them."

Second place for the hackathon went to MyProperty, a new service being built by Daniel Olel and team. Just as E-Ride addressed an existing problem and practice and streamlined it, MyProperty aims to connect buyers and sellers of properties around Uganda. As Olel, noted, many middle class Ugandans rely on brokers. Anyone looking for an apartment in New York knows how pricey middlemen can be, and Olel's goal is to use MyProperty to cut out the middleman and build trust among buyers and sellers (quite similar to RentHackr, which I reviewed last year).

And third place went to Tech Post, a startup near and dear to my heart if only because they're a blogging community focused on new technologies from Uganda or new technologies and how they apply to Uganda. Of all of the new businesses, they had the most developed prototype, with an existing site with tons of interesting content already in the mix.

What distinguished Mara's hackathon from most hackathons I've attended in any city was its emphasis on mentorship. Mentors came in and out throughout the event to answer participants' questions and help them formulate solid business plans and product pitches.

As Nigel Ball, who just stepped down as Mara's director (handing the reins to Delia Dean), noted in an interview with Core77, this is a deliberate and key part of their strategy: "Mara Launchpad is a great community space but there is more needed that just building community. This is why at Mara Foundation we are also focusing a lot on the entrepreneurs themselves, through our mentorship programme, and also providing financing through the Mara Launch Fund. "

The hackathon is an exciting new step for Mara, and they'll be hosting an event like this every six months to nurture new Ugandan talent. Time will ultimately tell if this Silicon Valley-inspired model can translate in the emerging "Silicon Savannah" of East Africa (Silicon Valley itself took time to develop as well). After living here for a few months now, I've been floored by the creative and technical energy in Kampala. It's exciting to see new infrastructure and systems coming into place to support that talent.

Community college learns that boosting retention comes with a cost

Research has identified several ways for colleges that enroll lesser-prepared students to improve their graduation rates. But college leaders are often wary of those solutions, because they can take a whack at the bottom line and challenge a tradition of open doors.

Klamath Community College recently went all in with several measures aimed at improving student retention, including mandatory orientation for students, mandatory advising and the elimination of late registration for courses. The college?s new president, Roberto Gutierrez, said he knew those policies could discourage or freeze out some students.

?We have a system that doesn?t reward student success. It rewards seat time.?
--Roberto Gutierrez, president of Klamath Community College

He was right. Klamath saw its enrollment decline roughly 20 percent last fall, when compared to the previous year. The small college, which is located in Southern Oregon and enrolls about 1,500 students, will receive $800,000 less from the state this year, because Oregon?s funding formula for two-year institutions is largely enrollment-driven. That?s more than 7 percent of Klamath?s total annual budget.

?We were driven by doing the right thing,? said Gutierrez, but ?it does hurt.?

The smaller numbers on campus may be due to other reasons besides students failing to register for courses in time or deciding after mandatory orientation and advising that college isn?t for them. And the college can?t say for sure what?s driving the shift. But Gutierrez, who became the college?s president last summer, thinks much of the decline is due to the retention efforts. If it?s even half of the driver, that?s $400,000 less this year.

?We have a system that doesn?t reward student success,? he said. ?It rewards seat time.?

While the college now faces a financial crunch, it might be better off in the long run. That?s because if students stick around longer and more make it to graduation, enrollment should stabilize or even improve.

Klamath's leaders said the retention efforts are in line with ambitious goals set by the state's Democratic governor, John Kitzhaber, who wants 40 percent of the state's residents to hold an associate degree or certificate by 2025. And few would argue with the college's desire to get more of its students to the finish line -- with a meaningful degree or certificate, that is.

?We?ve really encouraged colleges to do what?s good for students,? said Carol Lincoln, senior vice president for Achieving the Dream, a nonprofit group that works with community colleges. ?Just having their numbers up; who is that really helping??

Short-Term Pain, Long-Term Payoff?

Klamath Community College is an Achieving the Dream partner institution, which means the college has agreed to use data-driven decision-making to try to improve student success rates. Some of the initiatives championed by the group can be tough medicine.

Achieving the Dream is a vocal supporter of ?make it mandatory,? a refrain often used by Kay McClenney, an expert on community colleges and director of the Center for Community College Student Engagement. McClenney, backed by research, argues that mandatory orientations and advising can boost student retention rates.

For example, prior to last year, only 50 percent of students at Klamath were attending orientation. College officials said that means those students were missing out on vital information about the college and how to navigate it.

Yet many colleges resist the mandatory approach, feeling it is paternalistic and too prescriptive for the large numbers of adult students who attend community colleges, where the average age of students typically hovers around 25. And red tape and hassles, like mandatory scheduling, can discourage students who may have been on the fence about attending college in the first place.

Lincoln and Gutierez aren't shy with their take on this dilemma, however, saying that if students decide to drop out rather than going to orientation or meeting with academic advisers, then maybe they aren?t ready for college ? or the debt they might incur before dropping out later.

Late registration poses a similar, perhaps even more serious challenge. Adult students with fulltime jobs are probably more likely than their traditional-aged, nonworking peers to fail to register in time for courses. And overburdened community colleges are hardly easy bureaucracies to navigate for students, who are often the first in their families to attend colleges. By locking out students who try to sign up for a class a week or two after it?s begun, Klamath is essentially opting to restrict access.

But research has shown that students who register late are more likely to fail courses or drop out of college.

?You?re starting behind,? said Lincoln. ?It?s putting one more thing in front of a student that keeps them from succeeding.?

In that sense, Klamath is changing tack in a way that resembles recent decisions by a few for-profits, including the University of Phoenix and Kaplan University, which have created free trial periods for students. During those orientation weeks, students can find out whether they are ready for college and leave without spending any money or receiving federal financial aid. The universities can also decide that students are better served by not enrolling, at least for now.

Lincoln said that other Achieving the Dream colleges have absorbed recent enrollment hits they at least partially attribute to ending late registration. But enrollments are down around much of the country, for various reasons, so it?s hard to determine the role of student success efforts. And she said the move will eventually pay off for colleges.

?In the long run colleges will see a positive impact on their retention,? said Lincoln.

It?s too early to say conclusively if that?s happening at Klamath, but the early returns look good. College officials said fall-to-winter retention rates have jumped from approximately 60 percent for first-year students to 80 percent this year. If those improvements are sustained, they could substantially boost the college?s graduation rate, which is 17 percent, according to the U.S. Department of Education (which only counts first-time, full-time students). The college also has a 31 percent student ?transfer out? rate.

Gutierrez said he thinks most of the college?s faculty and staff back the new policies, and understand that they are aimed at improving student retention. And the college didn?t really have a choice, he said, ?if we mean what we say about student success.? Even so, it hasn?t been easy.

?I may be a short-term president,? Gutierrez said. He sounded like he was joking -- mostly.

Renewed fervor for Google lifts stock above $800

SAN FRANCISCO (AP) ? Google's stock price topped $800 for the first time Tuesday amid renewed confidence in the company's ability to reap higher profits from its dominance of Internet search and prominence in the growing mobile market.

The milestone comes more than five years after Google's shares initially hit $700. Not long after breaking that barrier in October 2007, the economy collapsed into the worst recession since World War II and Google's stock tumbled into a prolonged malaise that eventually led to a change in leadership.

Besides enriching Google's employees and other shareholders, the company's resurgent stock is an implicit endorsement of co-founder Larry Page. He replaced his managerial mentor, Eric Schmidt, as CEO in April 2011. Google's stock has risen by 36 percent since Page took over. By contrast, the benchmark Standard & Poor's 500 index has climbed by 15 percent over the same stretch.

Most of Google's gains have occurred in the past seven months ? a period that has overlapped with a sharp downturn in the stock price of rival Apple Inc. The iPhone maker's market value has plunged by about $230 billion, or 35 percent, since late September.

"All that Apple money had to go somewhere," said BGC Financial analyst Colin Gillis.

Standard & Poor's Capital IQ analyst Scott Kessler concurred, reasoning that many investors who have abandoned Apple are gravitating to one of its biggest rivals.

Google makes and distributes its free Android software to Samsung Electronics Co., HTC Corp. and other mobile device makers looking to compete with Apple's iPhone and iPad. Since its 2008 introduction, Android has established itself as the most popular mobile operating system, partly because the free software makes it easier for device makers to undercut Apple's prices for iPhones and iPads.

Android is set up to feature Google's search engine and other services, giving the company a chance to sell more ads.

"If you are looking at Apple's peers in its space and see who seems to be really doing well right now, it makes a lot of sense to invest in Google now," Kessler said.

Despite its diminished luster, Apple remains the most valuable U.S. company with a market value of $432 billion. Google now ranks third with a market value of $266 billion, with Exxon Mobil Corp. holding the spot in between at $402 billion.

Google's stock climbed $13.96, or 1.8 percent, to close Tuesday at $806.85.

Analysts who follow Google still see room for some modest gains. The stock's average price target among analysts surveyed by FactSet now stands at $834.40. Five of the 37 polled analysts are predicting Google's stock will surpass $900 within the next year.

"There are probably even going to be people talking whether Google's stock can get to $1,000," Kessler said. "Never underestimate the excitement that can be caused by a rising stock market and a rising security."

Gillis warned that Google's stock might retreat within the next six weeks, based on historical trading patterns. During the first quarter in each of the past five years, Google's stock has declined by at least 10 percent from its peak price within the three-month period. The trend may have something to do with the opening three months of the year being a traditionally sluggish period for advertising, according to Gillis.

"I fully expect investors to have another opportunity to buy Google's stock at prices below $800," Gillis said. His price target on Google remains at $760.

The significance of crossing the $800 threshold is largely symbolic. If Google had its way, the stock wouldn't even be priced near these levels.

The company, which is based in Mountain View, Calif., had hoped to split its stock last year in a move that would have at least temporarily halved the trading price by doubling the total number of outstanding shares. But the proposed stock split was put on hold until Google resolves a shareholder lawsuit alleging that the stock split unfairly cedes too much power to Page and fellow co-founder Sergey Brin. Page and Brin have been the company's largest shareholders since its inception. A trial on the lawsuit is scheduled to begin June 17 in a Delaware state court.

Assuming more investors wouldn't have rushed to buy more Google stock just because it split, the company's market value probably wouldn't have changed from its current level.

There is little dispute among analysts that Google appears well positioned for many years of prosperity for these reasons:

? Its Internet search engine remains the hub of the Web's biggest marketing network;

? Its YouTube video site has established itself as an increasingly attractive advertising vehicle and could broaden its reach as more people get Internet-connected televisions;

? Its Android software is running on more than 600 million smartphones and tablet computers, creating new advertising opportunities.

Google already dominates mobile advertising, with its U.S. revenue from that business expected to approach $4 billion this year, up 84 percent from nearly $2.2 billion in 2012, according to the research firm eMarketer. Google commands a 55 percent share of the mobile ad market, based on eMarketer's estimates. Google doesn't disclose how much of its $44 billion in annual worldwide ad revenue comes from mobile devices.

Some investors have raised concerns that mobile ads have been commanding lower prices than ads on regular Web pages, reducing the average rate for ads. The company is trying to address that with a revamped ad system that will prod more marketers to buy mobile ads when they are creating campaigns for desktop and laptop computers. That, Google hopes, will raise demand and thus prices.

Opinions about Google weren't as upbeat a few years ago. Although Google weathered the Great Recession better than most companies, its revenue growth slowed and its stock plummeted to as low as $247.30 near the end of 2008.

Things looked so bleak in 2009 that Google took the rare step of re-pricing stock options that had been doled out to its employees to give them a chance to make more money when the shares rebounded. The program allowed Google workers to swap their old stock options for new ones with an exercise price of about $308. The employees who have held on to the re-priced options would make nearly $500 per option if they were to exercise them now.

Although he didn't receive any of those re-priced options, Schmidt is poised to pocket a huge windfall by selling 42 percent of the shares that he owns in the company during the next year. The 3.2 million that Schmidt, now Google's executive chairman, has earmarked for sale are currently worth about $2.6 billion. Google says the stock sales are part of Schmidt's strategy to diversify his investment portfolio so less of his wealth is locked up in the company.

Even after the economy snapped out of the recession toward the end of 2009, Google's stock began to lag the rest of the market. Investors began to wonder if the company was losing its competitive age as it morphed from a hard-charging startup to giant organization with thousands of employees working in dozens of offices scattered around the world.

At the same time, Facebook was emerging as the Internet's fastest growing company in a meteoric rise. The social networking company had some people convinced it would eventually become a more important advertising vehicle than Google's search engine.

Perceptions have changed since Page became CEO. Under Page's leadership, Google has streamlined its decision-making and operations while closing dozens of its less popular services. It established its own toehold in social networking with the 2011 introduction of Google Plus.

Meanwhile, Facebook Inc. so far hasn't lived up to the hyperbole that that made its initial public offering of stock one of the biggest in U.S. history. Since going public at $38, Facebook's stock has sunk 24 percent.

By contrast, Google's stock has never slipped below its August 2004 IPO price of $85.

Andrew Rugasira: can coffee transform lives in Africa?

How can you tell when a story has ended? If it is an African story, such as the one Andrew Rugasira has to tell, closure is never likely to be satisfying or clear cut. Beginnings are more straightforward.

Rugasira's once-upon-a-time moment came nearly a decade ago, when he had a vision to start a coffee company in his native Uganda. He would, he determined, become the first African to collect and roast and market and sell quality coffee direct to British supermarkets. And, by that example, he would demonstrate his certain beliefs: that it was trade, not aid, that transformed communities and that change was never an imposed solution, but a positive choice made by those whose lives would be most affected by it.

The place Rugasira chose to base his coffee company, to start that story, the Rwenzori mountains ? the Mountains of the Moon ? looked a lot like a blank page. The lives of the 14,000 subsistence farmers who lived high above the town of Kasese, right on the war-torn border with the Democratic Republic of the Congo, had never been the stuff of written record. Their narratives were of survival rather than progress. Ambition meant getting through the next day and the next week, in thrall as they were to the suddenly shifting front lines of brutal cross-border conflict and the vagaries of farming a little scrap of land without decent tools or any technology, without transport or access to market, barely growing enough to feed themselves and their children, waiting for agents or middlemen to pass through and buy some coffee beans, maybe soon, maybe not, and never for a price that seemed fair.

Rugasira believed he could help to give the lives of those 14,000 farmers and their families a different shape. One that could take in measurable progress; that could see skills learned and retained in the community; that could reward consistent effort, introduce saving and planning and time horizons that included the real prospect of better lives for children and for grandchildren. The first step in rewriting those life stories would be to communicate an idea, Rugasira believed. So, aged 34, and after a career that had taken in event planning and business consultancy in Kampala, he went up into the mountains and started telling the farmers what he had in mind.

He recalls the first of those meetings, with a group of community leaders, in his book, A Good African Story, which details the progress of his vision and his company, the ways in which it has succeeded and the ways in which it has failed. "In Kasese, I shared my frustrations," he recalls, "at Africans always being seen [in the west and sometimes at home] as nothing more than beggars: incapable, deprived, poor and helpless. With their help, I told them, I was determined to make a change, however small, to alter this outlook. But the project could only work if we did this together."

At this point in Rugasira's speech, a young man who had been sitting quietly at the back of the room put up his hand to speak.

"My name is Charles Kahitson and I am from Nyakabingo in Rukoki sub-county," he said. "I want to tell you, Mr Andrew, that I am in fact a model farmer. If you come to Kasese to work with model farmers then I am one and I am willing to work with you."

And so it started. Over the next year, Rugasira, with the help of Kahitson and others, began to build up his network of farmers in the mountains who might share best farming practice, "wet-processing" coffee, rotating their crop, harvesting efficiently. At the same time, he helped to establish microfinance initiatives, particularly among women, promising a model of business in which his Good African coffee company would guarantee a consistent, fair market price and would share profits 50/50 with the farming community. In addition, Rugasira would go out into the world and sell their high-quality product and tell their story.

I first saw Rugasira recounting the opening chapters of that story in 2005 in the unlikely setting of the terrace of the House of Lords, where he had been invited to speak about his initiative beside a banner that read "Trade not Aid". Rugasira is a committed Christian, and a compelling orator, but he reserves much of his evangelism for the lessons of self-help, the wisdom of entrepreneurs, quoting as freely from business leaders he admires ? Jack Welch of General Motors, Lee Kun-hee of Samsung ? as from the Gospels. And that day, at the House of Lords, he could point to the minor miracle of his coffee on the shelves of Waitrose as evidence of the reality of his faith for those who doubted. Inspired by some of this message, a few weeks later I went out to the Mountains of the Moon to hear the tales of the farmers first hand.

In Kasese, Rugasira introduced me to some of the stars of his 14,000-strong "team". In turn, they proudly showed me the processing methods they had mastered, they talked of advances in yield and quality, the incremental improvements they had made to their one-room huts, and their eyes shone with possibility. Some stories stayed with me, like parables. There was the story of Charles Kahitson himself, who as a sideline from his coffee growing was experimenting with beekeeping, spreading the word about homemade hives, and honey, and imagining the Rwenzori valleys buzzing with life. (The only book Kahitson owned was on the technicalities of apiology and so enthralled was he by it that he had named his son Macmillan, after its publisher.)

There was the tale, too, of Milenai Muhindo, who talked quietly in simple declarative sentences of the way, soon after her husband had died, she had seen her three brothers killed in front of her by a militia group from Congo, who also burned her home to the ground. With the coming of the coffee company, though, she had still found some place in her life, as a single mother and farmer, for hope. She had started a microfinance group among the local women; she showed me the little ledger of how their savings were growing week by week. There were many other stories like these and by the time I ended that visit, I felt I had a sense of what even the tiniest change might mean for these people and how it was beginning to be effected.

In the years since then, I have seen Rugasira from time to time when he has been over in Britain, on his never-ending storytelling mission for contracts and capital. Those one-man trade delegations have sometimes appeared full of hope ? as he secured further contracts with Sainsbury's and Tesco ? and sometimes more desperate, as he sought to protect those hard-won agreements, beset by problems of financing and managing growth. He made good his promise to establish a coffee roasting plant to serve Rwenzori, proof that value could be added to the product where it was produced. He expanded to America, planned to grow the model into tea and chocolate, and he reported back on the small anecdotal changes in the lives of the farmers I had met ? how this man had bought a bicycle, that one had now saved to send his daughters to a good school.

A couple of years ago, six years since Good African was established, Rugasira took the surprising step of enrolling on an MSc course in African studies at Oxford University. Partly it was the fulfilment of an old promise he had made to himself and to his mother. Having studied at the School of Oriental and African Studies at the University of London after school, he had been forced home immediately after graduation by news of the death of his father, aged 51. He laid aside plans for postgraduate work and was cast prematurely in the role of man of the house in a country still unhinged by the brutal regimes of Idi Amin and Milton Obote. Oxford was put on hold for 20 years. When he did take up his place, he left behind in Uganda his wife, Jackie, and five children, as well as his business. I saw him a couple of times while he was pursuing a spartan regime of gym and study, trying to run Good African and be a father and husband from afar. One result of that period of reflection was his?book.

In a piece for the Times last week, a reviewer suggested the memoir was a piece of "premature triumphalism", that the story of Good African was not only incomplete, but the model as yet unproved. Rugasira accepts that his timing might look odd in a landscape of business literature that tends to deal in unqualified success. Even so, he told me, when we met last week: "I thought it was time to try to force a conversation. Everyone is suddenly talking about Africa being 'open for business'. But nobody seems to want to define what that might mean."

The book is full of Rugasira's vivid character, scholarly, argumentative and big-hearted, dismantling the agendas of NGOs, dwelling on the historical context of poor governance and corruption, detailing the ways in which real change in Africa is still an ambition rather than a reality. Its theme is not one of triumph, but of ongoing frustration and struggle. The context has changed since 2003, when Africa was still seen primarily as a place for charity rather than investment, but not always in useful ways.

"I think there are always two conversations taking place now," Rugasira says. "One is among the observers of Africa, the investing class. They point to the McKinsey report, which says African economic growth is running at 6% or 7%, in which they have an interest? But there is also another conversation going on, this time on the continent, among the increasingly young population, who are still looking for work, looking for capital. It doesn't matter how many times young African entrepreneurs are told Africa is open for business. It is still business on somebody else's terms..."

Much of Rugasira's anger remains directed at the good intentions of foreign aid and ring-fenced investment, which focuses on nebulous "capacity building" without ever targeting support directly at small business or wealth creation. "It is easier to plant a bore hole in some remote place and bring some media in to photograph it and say, look, these people have water. They are the same vulnerable, impoverished people, but now they have a bore hole. The question still has to be: how do you enable these people to build their own bore holes?"

He points to the transformations achieved in Singapore and South Korea: "There was no aid, just financial institutions geared by government not only to lend but to lend technical support, who would fund their trade shows and exhibitions and marketing?" And he references the Cambridge economist Ha-Joon Chang's book Kicking Away the Ladder, the story of how all major developed countries used interventionist and protectionist policies to get rich and now work to prevent underdeveloped countries doing the same.

Rugasira has close knowledge of that reality. Despite his indefatigable commitment, he has been beset with the African entrepreneur's catch-22. "In order to grow you have to have a long-term market expectation, but you have no access to long-term capital. I had African banks asking me for letters of credit from Tesco. I had to explain that is not really how it works." As a result of this mismatch of finance and culture, Waitrose and Sainsbury's ended up delisting Good African last year. "With Waitrose, we were just unable to meet its rate of sales; we didn't have the resources to do the promotion and marketing needed to expand." He hasn't given up hope of a return and in the meantime, as well as an expanding market in Africa, "Tesco has said we will go from 118 stores to 630".

As he has negotiated this journey, Rugasira has sometimes come close to defeat; he sold his house in Kampala and was forced to downshift with his family. There have been times when he has been unable to pay for the coffee brought to Kasese. But that in itself proved a lesson.

"It's funny," he says, "but it was only when it became clear that we as a company were also vulnerable financially that the farmers could see that we were serious. We became real. When we said, 'Look, we can't pay you this week', they didn't walk away, as I feared. They said, 'OK, keep the coffee and pay me next week.'"

Transformation, in this sense, he suggests, is full of unintended consequences. Having raised the quality and reliability of coffee production exponentially in Rwenzori, other bigger buyers have come in to compete.

It gives him cause for hope, not despair. "I said to my wife, Jackie, the things we have learned in the past eight years, where else on Earth could we have learned them? She agreed with me," he says and laughs. "But she also wants it fixed this year. Otherwise she will be looking to see how many places I have sent my CV?"

Given his commitment to change, Rugasira is often asked about political ambitions. He doesn't quite rule out the possibility but he is wary. "I just want to be a good president of Good African coffee. Politics has too many takers."

He is, if anything, a slightly more humble, perhaps wiser figure than he was when I first met him, though still as passionate. "I have learned that I'm not as important as I thought I was in this," he says. "You begin to effect a change, but the change is bigger than you. There are successes, but you are never going to say you have completely succeeded." What he hopes his book shows, he says, is "the dignity of proving we could do it for ourselves". He had just sent a few copies to his model farmers and received an excited phone call. "I just want to thank you, thank you for putting my name, Charles Kahitson, all over the world," the voice said. "But I didn't do it," Rugasira says to me. "Charles grasped the opportunity to do that for himself."
