Performance Auditing Best Practice

Climate Engineering: Technical Status, Future Directions, and Potential Responses;
Climate engineering technologies do not now offer a viable response to global climate change. Experts advocating research to develop and evaluate the technologies believe that research on these technologies is urgently needed or would provide an insurance policy against worst case climate scenarios--but caution that the misuse of research could bring new risks. Government reports and the literature suggest that research progress will require not only technology studies but also efforts to improve climate models and data. The technologies being proposed have been categorized as carbon dioxide removal (CDR) and solar radiation management (SRM). CDR would reduce the atmospheric concentration of CO2, allowing more heat to escape and thus cooling the Earth. For example, proposed CDR technologies include enhancing the uptake of CO2 in oceans and forests and capturing CO2 from air chemically for storage underground. SRM technologies would place reflective material in space or in Earth's atmosphere to scatter or reflect sunlight (for example, by injecting sulfate aerosols into the stratosphere to scatter incoming solar radiation or brightening clouds) or would increase the planet's reflectivity (for example, by painting roofs and pavements in light colors). GAO found these technologies currently immature, many with potentially negative consequences. Some studies say, for example, that stratospheric aerosols might greatly reduce summer precipitation in places such as India and northern China. Many experts advocated research because of its potential benefits but also recognized its risks. For example, a country might unilaterally deploy a technology with a transboundary effect. Research advocates emphasized the need for risk management, envisioning a federal research effort that would (1) focus internationally on transparency and cooperation, given transboundary effects; (2) enable the public and national leaders to consider issues before they become crises; and (3) anticipate opportunities and risks. A small number of those we consulted opposed research; they anticipated major technology risks or limited future climate change. Based on GAO's survey, a majority of U.S. adults are not familiar with climate engineering. When given information on the technologies, they tend to be open to research but concerned about safety.

Should we encourage Swine Flu parties?

Infectious-disease specialists say they understand the logic: surviving the current, apparently mild strain of the virus may be protective if a more virulent strain emerges next fall. But they are generally against it.

Dr. Anne Moscona, a flu specialist at Weill Medical College of Cornell University, said she had been called by a reporter for a women’s magazine “asking if mothers should hold swine flu parties, like chickenpox parties.”

(Chickenpox parties, at which children gather so they can all be infected by a child who has the pox, are often held by parents who distrust chickenpox vaccine or want their children to have the stronger immunity that surviving a full-blown infection affords and are willing to take the risk that their child will not get serious complications.)

“I think it’s totally nuts,” Dr. Moscona said. “I can’t believe people are really thinking of doing it. I understand the thinking, but I just fear we don’t know enough about how this virus would react in every individual. This is like the Middle Ages, when people deliberately infected themselves with smallpox. It’s vigilante vaccination — you know, taking immunity into your own hands.”

The idea has arisen from the history of the 1918 Spanish flu. A mild spring outbreak was followed by two deadly waves in the early and late winter of 1918-1919. Some believe, although there is little evidence beyond anecdotal reports in old newspapers, that those who got sick in the first wave were less likely to get sick in the second and third.

Many cite as the source of their thinking the book “The Great Influenza,” a history of the 1918 pandemic by John M. Barry.

Mr. Barry, in a telephone interview, said he had never publicly suggested deliberate self-infection, “but I used to joke with my wife, and I may have jokingly said it in speeches, that if a virus emerged and looked mild, I’d be on an airplane to Indonesia.”

A History of History
In the 6th century AD, the bishop of Tours began his history of the world with a simple observation that “A great many things keep happening, some of them good, some of them bad”.

For a phrase that captures the whole of history it’s among the best, but in writing about the past we are rarely so economical. From ancient epics to medieval hagiographies and modern deconstructions, historians have endlessly chronicled, surveyed and analysed the great many things that keep happening, declaring some of them good and some of them bad.

But the writing of history always illuminates two periods – the one history is written about and the one it is written in. And to look at how the writing of history has changed is to examine the way successive ages have understood their world. In short, there is a history to history.

The Trials of the Templars

At dawn on 13 October 1307 all the Templars in France were arrested by royal order, on the charge that they had been involved in secret blasphemous rituals. This led to other arrests of Templars in Europe, and an investigation by Pope Clement V. The University of Sydney Rare Books and Special Collections Library recently obtained trial documents from the Vatican archives, which John Pryor discusses with Rachael Kohn

Lamarck's Evolution - Two Centuries of Genius and Jealousy
In 2009 we celebrate the birthday of evolution. Before Charles Darwin, Jean-Baptiste de Lamarck created the first theory of evolution in 1809. However, his theory was discredited by most in the scientific community once Charles Darwin published his theory of evolution, 50 years later. Ross Honeywill tells us this fascinating story.

THE CONSOLATION OF PHILOSOPHY
;
In the 6th century AD, a successful and intelligent Roman politician called Boethius found himself unjustly accused of treason. Trapped in his prison cell, awaiting a brutal execution, he found solace in philosophical ideas - about the true nature of reality, about injustice and evil and the meaning of living a moral life. His thoughts did not save him from death, but his ideas lived on because he wrote them into a book. He called it The Consolation of Philosophy.

The Consolation of Philosophy was read widely and a sense of consolation is woven into many philosophical ideas, but what for Boethius were the consolations of philosophy, what are they more generally and should philosophy lead us to consolation or lead us from it?

U=EV/ID

Chronic procastinators, who make up 20 per cent of the population, are more impulsive and erratic than other people and less conscientious about attention to detail and obligations to others, he says in his forthcoming book, The Procrastination Equation: Today's Trouble with Tomorrow.

The psychologist, from the University of Calgary, has subsequently formed an equation for why people procrastinate, which began by studying 250 college students.

The equation is U=EV/ID.

The 'U' stands for utility, or the desire to complete a given task. It is equal to the product of E, the expectation of success, and V the value of completion, divided by the product of I, the immediacy of the task, and D, the personal sensitivity to delay.

Prof Steel says procrastination is becoming a bigger issue because many more jobs are "self-structured", with people setting their own schedules.

Primal, Acute and Easily Duped: Our Sense of Touch;
Touch also turns out to be easy to fool. Among the sensory tricks now being investigated is something called the Pinocchio illusion. Researchers have found that if they vibrate the tendon of the biceps, many people report feeling that their forearm is getting longer, their hand drifting ever further from their elbow. And if they are told to touch the forefinger of the vibrated arm to the tip of their nose, they feel as though their nose was lengthening, too.

Some tactile illusions require the collusion of other senses. People who watch a rubber hand being stroked while the same treatment is applied to one of their own hands kept out of view quickly come to believe that the rubber prosthesis is the real thing, and will wince with pain at the sight of a hammer slamming into it. Other researchers have reported what they call the parchment-skin illusion. Subjects who rubbed their hands together while listening to high-frequency sounds described their palms as feeling exceptionally dry and papery, as though their hands must be responsible for the rasping noise they heard. Look up, little Pinocchio! Somebody’s pulling your strings.
