Sherpa Tenzing Norgay


The world had its glory at any mountaineer, the first on the summit of the highest mountain in the world, but for Tenzing Norgay is a special honor for this achievement.

Over a period of about twenty years ago, they are part of each broadcast to bind a man at the summit of the mountain. Everest. He climbed as a gatekeeper and modest as a respected member of the team to climb. He had a total confident armies (1936 1953) 1947, on the likelihood that the same Could him the opportunity to focus on the summit. In 1953, he probably had more time on Mount Sinai. Everest than any other human being - and has at its peak. Only a few months before his successful ascent by Edmund Hillary, Raymond M. Lambert and the Swiss expedition of 1952, was up to 1000 feet of the summit - the highest point in the world, everything has achieved until then. Unlike most of his colleagues Sherpas from the time around, in the whole of the escalation was just a way of making a life difficult, Tenzing desperately wanted at the summit of the mountain. Everest and has spent most of his life to this goal. "Because in my heart," he said, "I need ... the attractiveness of Everest was for me more than any power on earth." If ever there was someone who deserved it, in the first place, he was Tenzing.

But there are other reasons why it was that the honor, along with Sir Edmund Hillary. Until the Second World War, most countries in Asia have been under the domination of the West. At the beginning of 1950, its residents finally felt their own strength and identity, and Tenzing, the achievement of a goal that everyone recognizes as one of the highest, if a convergence point for a new kind of pride and a new vision of the future . "For millions in the world today," wrote James Ramsay Ullman, shortly after the climb, Tenzing "is an event of divinity: an avatar of Lord Siva, a reincarnation of the Buddha. For millions of others still too high for the people to be confused with God, it is a mortal figure highest importance. Symbolically, so literally, Tenzing on Mount Everest was a man against the sky, almost modest, was the first in Asia in history to reach, the World Bank and stature of world renown . for other Asians And his masterpiece was not responsible for the escalation of a mountain, but a good omen for themselves and for the future of our world. "


Tenzing birth may have been modest, as Ullman says, but he also had the good fortune to portents. His parents lived in the high mountain village in Nepal Thame, but at the time of his birth, his mother was in the sanctuary in a holy place called Lha Ghang in eastern Nepal.
Tenzing, whose name has been changed, from a large Namgyal Lama Wangdi is the name that we know him today ( "Norgay" means "happiness"), himself a chance to have believed in favor. He knew the beginning of His life, no matter whether they are about their fate tend yaks in the high mountains, and in the moment when he was 13, already has a secret trip in Kathmandu, the capital of Nepal. Five years later, he took over Relocated (again without the permission of their parents) in Darjeeling, India, where he hopes to be able to participate in one of the expeditions in the British Mt Everest was organized. Nepal at the time was closed to foreigners, which means that all the tests were on the north side of the mountain. 1921, the British drew on Darjeeling Sherpa's strong support of the population to get the Mount Everest and the 'climbing.


With a bit of a trématode, Tenzing is about Eric Shipton's Everest Expedition 1935. It was at the time 19 and newly married - Phuti Dawa, a girl who lives in Darjeeling Sherpa. His performance in its ascent was such that he had no difficulty, set to become next British Everest expeditions in 1936 and 1938. When the Second World War ended the series, the official Everest expeditions, he is convinced, is secretly Earl Denman affected by Tibet to do what he knew was a little wild and pressure to reach the summit.


Dawa Phuti had died in 1944, he remaria a year later, Ang Lahmu, another Sherpa. Big-time Everest climb had been suspended during the Second World War, but Tenzing not stop climbing. Although his name is indelibly with Everest, he also took part in the expeditions of the Nanda Devi India, Pakistan Tirich Mir and Nanga Parbat, as well as Nepal and India Lang Tang area of Garwhal, where he was teammates and make the first pitch. In 1948, he, together with the famous Giuseppe Tucci Tibetologist at the archaeological excavations in Tibet, and in all likelihood, was one of the few people they deal with the irascible and eccentric scientists.


Nevertheless, it was the Everest, in which he mainly was interested. In a world that at the end of the war, Nepal opened its borders to foreigners in the same time that the Chinese invasion of Tibet closed the northern road. The British had longer the monopoly on Mount Everest attempts and Tenzing in 1952, was asked to Switzerland to achieve, not only as a member of the crew of Sherpa, but as a fellow climber, the two trials are the first on the summit. This is the first of these Tenzing reached the 28250 feet (just 778 feet below the summit), with Lambert. The second, in the winter, the attempt failed because of bad weather.

The British believed that 1953 was the last chance to be adopted at the first summit of Everest, and threw their plans in the aftermath, with the less fortunate. Luck is of course a factor, but it is perhaps more of a willingness to look at the best chances of success has caused their place at the summit Tenzing team with Hillary. On one end, it is also a triumph for Tenzing (for Asia), as for the British, he won this honor with his crew in New Zealand.

After Everest, what? It is difficult to think that to a greater glory, whether in the field of mountain climbing and others. And after they conquered the highest mountain in the world, the objective is to the left with dreaming?


If he is elected or not, is now Tenzing world. He has received numerous awards and was celebrated, among other things, by the state and government leaders of the world and heads of state. (The Nehru family came to visit Darjeeling, and there's a photo of them at home - which includes three generations of a meeting of the Prime Minister and three future prime minister.) He was everywhere in the world and has much to travel. It will be the first director of the newly founded city Himalayan Mountaineering Institute, a position he held during 22 years. He called the big house Darjeeling, which was paid to him by drawing public "Ghang Lha", a name of the family is of particular importance because of his connection with his birth.

He has in his new life with grace, and yet it was not always easy for him. It was a political symbol, which he unverschuldet in the controversy is not understood or environment. He was a simple man who loved life and is a simple and direct. He has never felt uncomfortable in a world where people are accustomed to use, which are their own purposes.

After Ang Lhamu died in 1964, he married Daku, a girl from Darjeeling, whose family from his home in Nepal. One of her three sons, Jamling, was followed in the footsteps of his father, at the summit of the mountain. Everest in 1996.

Tenzing died in 1986. The procession, after his funeral bier has more than one kilometre long.

that same year he married his cousin Elsa Louvain Thal, death, in 1936. He died on April 18, 1955 in Princeton, New Jersey.

Deaf And Ness Seizures Result When In Mysterious protein Deleted Mice


Science Daily (Jan. 28, 2008) - Scientists have discovered that mice genetically engineered to lack a particular protein in the brain and have profound deafness, seizures. The finding suggests a pathway, they say, for exploring the causes of hereditary deafness in humans and epilepsy.

More broadly, the discovery provides an entry point for resisting new insight into the role of glutamate, the chemical messenger carried by the protein, says the team, led by scientists at the University of California, San Francisco. Glutamate is involved in virtually every brain function, including sensory imagination, learning and memory.

The missing protein is a particular "vesicular transport neurotransmitter," a machine nerve cells within that ferry chemical messengers, or "neurotransmitters," from the fluid-filled vesicles into cytoplasm that are positioned at the tips of nerve cells and serve to release onto neurotransmitters Neighboring Cells. Carrier neurotransmitters and work together to make all possible neural communication essentially in the brain.

While the neurotransmitter glutamate is the major excitatory messenger in the brain, the neurotransmitter GABA is the major inhibitory messenger, sending signals that reduce agitation and anxiety. Two other neurotransmitters, dopamine and serotonin, modulate the activity of neural circuits influence mood to sleep and other aspects of behavior.

Scientists have known for several years about two vesicular glutamate transporters, VGLUT1 and VGLUT2. As would be predicted, they are expressed on nerve cells that release glutamate. More recently, scientists have identified VGLUT3. To their surprise, they have discovered that VGLUT3 is primarily expressed by nerve cells that GABA release, acetylcholine and serotonin, another neurotransmitter. VGLUT3 is also released in some non-nerve cells, tissues outside the brain. These findings led scientists to suspect that might VGLUT3 support function, other than some neurotransmission.

In the current study, published in the Jan 24, 2008 issue of Neuron, the team explored the role of VGLUT3 in mice genetically engineered to lack the forwarder. The effect was dramatic.

"Mice lacking the shipper are completely deaf from birth," says the senior author of the study, Robert Edwards, MD, professor of neurology and physiology at University of California, San Francisco. "Moreover, they had significant seizures.

As the gene encodes VGLUT3 that is known to have sequence changes in humans, it is possible that these or other changes may be the underlying cause of deafness or epilepsy in humans, according to the research. They plan to screen people with these conditions for changes in the gene vglut3, says the first author of the study, Rebecca Seal, PhD, post a fellow in the laboratory Edwards

In addition, because the mice in the study lacked the protein in all cells that would normally make it, the team plans to make a "conditional knockout", in which the gene is inactivated only in specific types of nerve cells. This will reveal which VGLUT3 nerve cells expressing a particular account for brain function.

At the outset of the study, the team VGLUT3 knew that was expressed during brain development by a population of inhibitory GABAergic-brainstem in the pathway that transmits information about sound. They suspected that the absence of VGLUT3 - which would allow the release of the excitatory glutamate - might produce a subtle defect in sound localization. Instead, the animals were completely deaf.

The explanation, they learned, was that VGLUT3 contributes to the release of glutamate at a key point in the production of sound. It turns out that inner hair cells of the cochlea, which are known to convert the auditory input, or signal, glutamate release, VGLUT3 express, transporters and contributes to the release of the first onto glutamate neurons in the pathway that carries into the sound Brain. Without VGLUT3, No. glutamate that is released at synapses.

The scientists also knew that from the outset VGLUT3 is expressed by a subset of - in the hippocampus and cortex that are known to release the inhibitory transmitter GABA. The presence of these VGLUT3-might also suggested that the release excitatory glutamate. Since inhibitory-contribute to a range of brain wave oscillations active, the team hypothesized that the disruption of these systems might affect brain wave activity in the cerebral cortex.

In fact, EEG (electroencephalograph) revealed that all of the mice had seizures, and even when they were having full-blown attacks they had electrical discharges in abnormal brain, known as "epilepiform activity. Surprisingly, the seizures - which last Up to two minutes - were accompanied by little or no change in behavior.

The team plans to screen young patients with hereditary or early-onset epilepsy to see if they have changes in this protein, says Edwards.

Since VGLUT3 may be required for relatively subtle aspects of behavior elicited not easily in a mouse, the research would also like to study and identify human patients, according to Edwards. Neuromodulatory The effect of glutamate release by serotonin, he says, may be easier to detect in humans.

"If we found lacking VGLUT3 patients," he says, "we could carry out psychological testing, which in turn would give us an idea why most serotonin and glutamate release.

"This is a case of a mouse model to patients leading us who will, in turn, suggest additional roles for functional glutamate that we can test in the mouse. The results will help us to understand basic brain function and how it goes awry in Disease . "

Albert Einstein


The Nobel Prize for Physics in 1921

Albert Einstein was born in Ulm, Baden-Wurttemberg, Germany, March 14, 1879. Six weeks later, the family pulled in Munich, where he started his education at the last-Luitpold Gymnasium. Later, he moved to Italy and continued his studies Albert and Aarau, Switzerland and in 1896, he joined the Swiss Federal Institute of Technology in Zurich to be trained as a teacher of physics and mathematics. In 1901, when she got her diploma, which acquired Swiss nationality and the right, when he was able, a doctrine of the post, he took a position as technical assistant to the Swiss Patent Office. During the year 1905, he graduated doctor.

During his stay in the Patent Office and leisure, which generates most of its valuable work and in 1908, lectured at Berne. In 1909, he was an associate professor in Zurich, in 1911 a professor of theoretical physics in Prague, return flight back to Zurich in the coming years to fill a similar position. During the year 1914, he was appointed director of the Kaiser Wilhelm Institute of Physics and professor at the University of Berlin. He became a German citizen in 1914 1933, when he renounces citizenship, for political reasons, and emigrated to the Americas, with the position of professor of theoretical physics at Princeton *. He became a United States citizen in 1940 at the age of retirement relieved of his duties in 1945.

After World War II, Einstein was a key dimension of the movement of global governance, which he offered the chairmanship of the State of Israel, who went and worked with Dr. Chaim Weizmann and the founding of the Hebrew University of Jerusalem.

Einstein always have a clear vision of the problems of physics and the determination to solve them. He had a strategy for its own account and was able to assume the main steps on the road to his goal. He followed his most success as a simple Stepping stones to the next.

At the start of the scientific work, Einstein recognized the shortcomings of Newtonian mechanics and the theory of relativity was the outcome of the process, the laws of mechanics with the laws of the electromagnetic field. It looked like the problems of classical statistical mechanics and problems, as well as quantum theory: This led to a statement from Brown motion of the molecules. He studied the thermal properties of light with low density of radiation and its observations, the keystone of the photon theory of light.

In the early days in Berlin, Einstein postulated that the correct interpretation of the theory of relativity must also provide a theory of gravitation in 1916, "published by the paper on the theory of general relativity. During this period, but focused on the problems of radiation theory and statistical mechanics.

In 1920, started the construction of Einstein theories of single material, although it continues to work on the probabilistic interpretation of quantum theory, who was involved in this kind of work in America. It contributed to the statistical mechanics and the development of quantum theory monatomic gas, and also has done work in the context of atomic transition opportunities and relativistic cosmology.

After his retirement, he continued, with the standardization of basic concepts of physics, on the other hand, geometrisation, for the majority of individuals.

Einstein, of course, research is very well, and particularly the most important projects special theory of relativity (1905), Relativity (in English translation, 1920 and 1950), The General Theory of Relativity (1916), with the perspective of the theory of motion Brown (1926) and The Evolution of Physics (1938). Among the scientific work and not on Zionism (1930), Why war? (1933), My Philosophy (1934) and Out of My Years Later (1950) is perhaps the most important.

Albert Einstein was awarded an honorary doctorate from the An science, medicine and philosophy in many European and American universities. During 1920 - has held conferences in Europe, the Americas and the Far East, who received scholarships or participation in all major scientific academies of the world. He has received numerous awards and recognition for his work, including the Copley Medal of the Royal Society of London in 1925 and the Medal of the Franklin Franklin Institute, 1935.

Gift of Einstein led inevitably to his flat in a large intellectual loneliness and, for relaxation, music played an important role in his life. He married Mileva Maric in 1903, and had a daughter and two sons, the marriage was dissolved in 1919 and that same year he married his cousin Elsa Louvain Thal, death, in 1936. He died on April 18, 1955 in Princeton, New Jersey.

Some beekeepers of the World Explorer


Sir Edmund Hillary, who was born in 1919 and grew up in Auckland, New Zealand. He was in New Zealand, he has concerned and mountaineering. Although his life as a beekeeper, he climbed mountains in New Zealand, then in the Alps, and finally, in the Himalayas, where he climbed 11 summits of more than 20000 metres. At that time, Hillary was ready to join the highest mountain in the world.

Mt Everest is situated between Tibet and Nepal. Between 1920 and 1952, seven major expeditions had failed to reach the summit. In 1924, the famous mountaineer George Leigh-Mallory, in the first trial. During the year 1952, a team of mountaineers Swiss was forced to return after reaching the southern tip, at 1000 metres from the summit.

Edmund Hillary and education was Everest expeditions in 1951 and again in the year 1952. These uses Hillary has attracted the attention of Sir John Hunt, head of a mission sponsored by the Joint Committee of the Himalayas Alpine Club of Great Britain and the Royal Geographic Society, for the attack on Everest in 1953.

The expedition reached the summit of the South in May, but all but two mountaineers, who most constrained by the exhaustion of height. Finally, Hillary and Tenzing Norgay, a native Nepali mountaineer who participated in five previous Everest-Tours, were the only members of the party, which is capable, the latest attack on the summit. The 11.30 on the morning of May 29, 1953, Edmund Hillary and Tenzing Norgay reached the summit 29,028 feet above sea level, the highest point on Earth. As notable, given that the performance of the achievement of the Summit was the climb treacherous resume his head.

Coincidentally, the conquest of Mount Everest was announced that the British public on the eve of the coronation of Queen Elizabeth II. The triumph of a British expedition, conducted in conjunction with the inauguration of the young queen has done much to restore the confidence of a nation tired of long years of war and post-war needs time. Edmund Hillary returned to England with other climbers and Queen was awarded a knighthood.

Now famous, Sir Edmund Hillary was exploration of Antarctica and New Zealand began the portion of the Trans-Antarctic Expedition of 1955 to 1958. In 1958, he took part in the first expedition to the South Pole mechanized. Hillary went to the mountains to organize more shipments, but as the years passed, he became increasingly interested in the welfare of the Nepalese people. In the 1960's, he returned to Nepal in the Help Center for the Development of Society, construction of clinics, hospitals and schools 17.

In order to facilitate these projects, two airstrips built. These airstrips had the unintended consequence will bring more tourists and aspirants remote mountain in the region. The Nepali put more of their forests for fuel for mountaineers. Edmund Hillary was concerned by the deterioration of the environment in the Nepali Himalayas, and convinced the government, laws on the protection of forests and explain the region around Everest National Park. The Nepali can not afford to finance this project, and he himself had no experience in the management of the park. Hillary took advantage of his great prestige for the government of New Zealand to the need for aid.

As a result of the success of the Expedition Everest, Hillary and Sir John Hunt has published his account of the expedition, the ascent of Everest. This book was published in the United States as "The Conquest of Everest. Sir Edmund Hillary's autobiography Nothing Venture, Nothing Win, in 1975, was published. In 1979, he published by the ocean to the sky, an account his expedition in 1977, from the mouth of his visit to Its source in the Himalayas.

Sir Edmund life has been overshadowed by the loss of his wife and daughter in a plane crash in 1975. He continued to occupy, environmental and humanitarian causes, on behalf of the Nepali people for the rest of his life. He died at home in New Zealand at the age of 88, betrauert of his compatriots and legions of fans all over the world.

Health effects of the Chernobyl accident: an overview


On 26 April 1986, explosions at reactor number four of the nuclear power plant at Chernobyl in Ukraine, a Republic of the former Soviet Union at that time, led to huge releases of radioactive materials into the atmosphere. These materials were deposited mainly over countries in Europe, but especially over large areas of Belarus, the Russian Federation and Ukraine.

An estimated 350 000 clean-up workers or "liquidators" from the army, power plant staff, local police and fire services were initially involved in containing and cleaning up the radioactive debris during 1986-1987. About 240 000 liquidators received the highest radiation doses while conducting major mitigation activities
within the 30 km zone around the reactor. Later, the number of registered liquidators rose to 600 000, although only a small fraction of these were exposed to high levels of radiation.


In the spring and summer of 1986, 116 000 people were evacuated from the area surrounding the Chernobyl reactor to non-contaminated areas. Another 230 000 people were relocated in subsequent years.

Currently about five million people live in areas of Belarus, the Russian Federation and Ukraine with levels of radioactive caesium deposition more than 37 kBq/m2 1 . Among them, about 270 000 people continue to live in areas classified by Soviet authorities as strictly controlled zones (SCZs), where radioactive caesium contamination exceeds 555 kBq/m2.

Evacuation and relocation proved a deeply traumatic experience to many people because of the disruption to social networks and having no possibility to return to their homes. For many there was a social stigma associated with being an "exposed person".

In addition to the lack of reliable information provided to people affected in the first few years after the accident, there was widespread mistrust of official information and the false attribution of most health problems to radiation exposure from Chernobyl.

This fact sheet gives an overview of the health effects of the Chernobyl accident that can be established from high quality scientific studies. For people most affected by the accident, provision of sound, accurate information should assist with their healing process.

WHO health effects review

Within the UN Chernobyl Forum initiative the World Health Organization (WHO) conducted a series of expert meetings from 2003 to 2005 to review all scientific evidence on health effects associated with the accident. The WHO Expert Group used as a basis the 2000 Report of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), updated with critical reviews of published literature and information provided by the governments of the three affected countries. The Expert Group was composed of many scientists who had conducted studies in the three affected countries as well as experts world wide. Special health care programmes, established to treat people in the three countries which were most affected by the accident, were also considered. This resulted in a WHO report on "Health Effects of the Chernobyl Accident and Special Health Care Programmes" (see www.who.int/ionizing_radiation).

The WHO Expert Group placed particular emphasis on scientific quality, using information mainly in peer-reviewed journals, so that valid conclusions could be drawn. In addition, comparisons were made with the results from studies of people involved in previous high radiation-exposure situations, such as the atomic bomb survivors in Japan.

Radiation exposure

Ionizing radiation exposure is measured as "absorbed dose" in gray (Gy). The "effective dose" measured in sievert (Sv) takes account of the amount of ionizing radiation energy absorbed, the type of radiation and the susceptibility of various organs and tissues to radiation damage. For most exposures from the Chernobyl accident, absorbed doses are similar to effective doses (i.e. 1Gy is approximately equal to 1 Sv).

As human beings we are continually exposed to ionizing radiation from many natural sources, such as cosmic rays, and naturally occurring radioactive materials in all the foods we eat, fluids we drink and air we breath. This is called natural background radiation.

UNSCEAR reports that the average natural background radiation dose to human beings worldwide is about 2.4 mSv2 each year, but this varies typically over the range 1-10 mSv. However, for a limited number of people living in known high background radiation areas of the world, doses can exceed 20 mSv per year. There is no evidence to indicate this poses a health risk.

For most people more than half of their natural background radiation dose comes from radon, a radioactive gas that can accumulate in homes, schools and workplaces. When inhaled, the radiation exposure from radon may lead to lung cancer. Radiation doses to humans may be characterized as low-level if they are comparable to natural background levels.

Doses received from the Chernobyl accident

Below are the total average effective doses accumulated over 20 years by the highest Chernobyl exposed populations. These can be compared with the average doses people normally receive from natural background over 20 years. Doses from typical medical procedures are also given for comparison purposes.

Population (years exposed) number Average total in 20yrs (mSv)1
Liquidators (1986–1987) (high exposed) 240 000 >100
Evacuees (1986) 116 000 >33
Residents SCZs (>555 kBq/m2)(1986–2005) 270 000 >50
Residents low contam. (37 kBq/m2) (1986–2005) 5 000 000 10–20
Natural background 2.4 mSv/year (typical range1-10, max >20) 48
Approximate typical doses from medical x-ray exposures per procedure:
whole body CT scan 12 mSv
mammogram 0.13 mSv
chest x-ray 0.08 mSv

[1] These doses are additional to those from natural background radiation.

While the effective doses of most of the residents of the contaminated areas are low, for many people, doses to the thyroid gland were large from ingestion of milk contaminated with radioactive iodine. Individual thyroid doses ranged from a few tens of mGy to several tens of Gy.

Apart from the people exposed to high levels of radioactive iodine mentioned above, only those liquidators who worked around the stricken reactor in the first two years after the accident (240 000), the evacuees (116 000), some of whom received doses well in excess of 100 mSv, and the residents of the highly contaminated SCZs (270 000), received doses significantly above typical natural background levels. Current residents of the low contaminated areas (37 kBq/m2) still receive small doses above natural background levels, but these are well within the typical range of background doses received world-wide. For comparison, the high radiation dose a patient typically receives from one whole body computer tomography (CT) scan is approximately equivalent to the total dose accumulated in 20 years by the residents of the low contaminated areas following the Chernobyl accident.

Thyroid cancer

A large increase in the incidence of thyroid cancer has occurred among people who were young children and adolescents at the time of the accident and lived in the most contaminated areas of Belarus, the Russian Federation and Ukraine. This was due to the high levels of radioactive iodine released from the Chernobyl reactor in the early days after the accident. Radioactive iodine was deposited in pastures eaten by cows who then concentrated it in their milk which was subsequently drunk by children. This was further exacerbated by a general iodine deficiency in the local diet causing more of the radioactive iodine to be accumulated in the thyroid. Since radioactive iodine is short lived, if people had stopped giving locally supplied contaminated milk to children for a few months following the accident, it is likely that most of the increase in radiation-induced thyroid cancer would not have resulted.

In Belarus, the Russian Federation and Ukraine nearly 5 000 cases of thyroid cancer have now been diagnosed to date among children who were aged up to 18 years at the time of the accident. While a large number of these cancers resulted from radiation following the accident, intense medical monitoring for thyroid disease among the affected population has also resulted in the detection of thyroid cancers at a sub-clinical level, and so contributed to the overall increase in thyroid cancer numbers. Fortunately, even in children with advanced tumours, treatment has been highly effective and the general prognosis for young patients is good. However, they will need to take drugs for the rest of their lives to replace the loss of thyroid function. Further, there needs to be more study to evaluate the prognosis for children, especially those with distant metastases. It is expected that the increased incidence of thyroid cancer from Chernobyl will continue for many years, although the long-term magnitude of the risk is difficult to quantify.

Leukaemia and non-thyroid solid cancer

Ionizing radiation is a known cause of certain types of leukaemia (a malignancy of blood cells). An elevated risk of leukaemia was first found among the survivors of the atomic bombings in Japan some two to five years after exposure. Recent investigations suggest a doubling of the incidence of leukaemia among the most highly exposed Chernobyl liquidators. No such increase has been clearly demonstrated among children or adults resident in any of the contaminated areas. From the experience of the Japanese bomb survivors it is possible that a large proportion of the leukaemia cases that could be linked to Chernobyl have already occurred, now that 20 years have passed since the accident. However, further studies are needed to clarify this.

While scientists have conducted studies to determine whether cancers in many other organs may have been caused by radiation, reviews by the WHO Expert Group revealed no evidence of increased cancer risks, apart from thyroid cancer, that can clearly be attributed to radiation from Chernobyl. Aside from the recent finding on leukaemia risk among Chernobyl liquidators, reports indicate a small increase in the incidence of pre-menopausal breast cancer in the most contaminated areas, which appear to be related to radiation dose. Both of these findings, however, need confirmation in well-designed epidemiological studies. The absence of demonstrated increases in cancer risk – apart from thyroid cancer – is not proof that no increase has occurred. Based on the experience of atomic bomb survivors, a small increase in the risk of cancer is expected, even at the low to moderate doses received. Such an increase, however, is expected to be difficult to identify.

Mortality

According to UNSCEAR (2000), 134 liquidators received radiation doses high enough to be diagnosed with acute radiation sickness (ARS). Among them, 28 persons died in 1986 due to ARS. Other liquidators have since died but their deaths could not necessarily be attributed to radiation exposure.

An increased number of cancer deaths can be expected during the lifetime of persons exposed to radiation from the accident. Since it is currently impossible to determine which individual cancers were caused by radiation, the number of such deaths can only be estimated statistically using information and projections from the studies of atomic bomb survivors and other highly exposed populations. It should be noted that the atomic bomb survivors received high radiation doses in a short time period, while Chernobyl caused low doses over a long time. This and other factors, such as trying to estimate doses people received some time after the accident, as well as differences in lifestyle and nutrition, cause very large uncertainties when making projections about future cancer deaths. In addition, a significant non-radiation related reduction in the average lifespan in the three countries over the past 15 years caused by overuse of alcohol and tobacco, and reduced health care, have significantly increased the difficulties in detecting any effect of radiation on cancer mortality.

Although there is controversy about the magnitude of the cancer risk from exposure to low doses of radiation, the US National Academy of Sciences BEIR VII Committee, published in 2006, a comprehensive review of the scientific evidence, and concluded that the risk seems to continue in a linear fashion at lower doses without a threshold (this is called the “linear no-threshold” or LNT model). However, there are uncertainties concerning the magnitude of the effect, particularly at doses much lower than about 100 mSv.

The Expert Group concluded that there may be up to 4 000 additional cancer deaths among the three highest exposed groups over their lifetime (240 000 liquidators; 116 000 evacuees and the 270 000 residents of the SCZs). Since more than 120 000 people in these three groups may eventually die of cancer, the additional cancer deaths from radiation exposure correspond to 3-4% above the normal incidence of cancers from all causes.

Projections concerning cancer deaths among the five million residents of areas with radioactive caesium deposition of 37 kBq/m2 in Belarus, the Russian Federation and Ukraine are much less certain because they are exposed to doses slightly above natural background radiation levels. Predictions, generally based on the LNT model, suggest that up to 5 000 additional cancer deaths may occur in this population from radiation exposure, or about 0.6% of the cancer deaths expected in this population due to other causes. Again, these numbers only provide an indication of the likely impact of the accident because of the important uncertainties listed above.

Chernobyl may also cause cancers in Europe outside Belarus, the Russian Federation and Ukraine. However, according to UNSCEAR, the average dose to these populations is much lower and so the relative increase in cancer deaths is expected to be much smaller. Predicted estimates are very uncertain and it is very unlikely that any increase in these countries will be detectable using national cancer statistics .3

Cataracts

The lens of the eye is very sensitive to ionizing radiation and cataracts are known to result from effective doses of about 2 Sv. The production of cataracts is directly related to the dose. The higher the dose the faster the cataract appears.

Chernobyl cataract studies suggest that radiation opacities may occur from doses as low as 250 mSv. Recent studies among other populations exposed to ionizing radiation (e.g. atomic bomb survivors, astronauts, patients who received CT-scans to the head) support this finding.

Cardiovascular disease

A large Russian study among emergency workers has suggested an increased risk of death from cardiovascular disease in highly exposed individuals. While this finding needs further study with longer follow-up times, it is consistent with other studies, for example, on radiotherapy patients, who received considerably higher doses to the heart.

Mental health and psychological effects

The Chernobyl accident led to extensive relocation of people, loss of economic stability, and long-term threats to health in current and possibly future generations. Widespread feelings of worry and confusion, as well as a lack of physical and emotional well-being were commonplace. The dissolution of the Soviet Union soon after the Chernobyl accident, and the resultant instability in health care, added further to these reactions. High levels of stress, anxiety and medically unexplained physical symptoms continue to be reported among those affected by the accident.

The accident has had a serious impact on mental health and well-being in the general population, mainly at a sub-clinical level that has not generally resulted in medically diagnosed disorders. Designation of the affected population as “victims” rather than “survivors” has led to feelings of helplessness and lack of control over their future. This has resulted in excessive health concerns or reckless behaviour, such as the overuse of alcohol and tobacco, or the consumption of mushrooms, berries and game from areas still designated as having high levels of radioactive caesium.

Reproductive and hereditary effects and children's health

Given the low radiation doses received by most people exposed to the Chernobyl accident, no effects on fertility, numbers of stillbirths, adverse pregnancy outcomes or delivery complications have been demonstrated nor are there expected to be any. A modest but steady increase in reported congenital malformations in both contaminated and uncontaminated areas of Belarus appears related to improved reporting and not to radiation exposure.

WHO's role

The Expert Group report is a milestone in WHO´s efforts to assess and mitigate the health impact of the Chernobyl accident. WHO will actively promote the research and practical recommendations given in this report. In addition WHO will ensure that the people most affected by the Chernobyl accident will be provided with scientifically factual information that will allow them to make better-informed decisions about their health and future .

Atlantic Salmon


On both sides of the Atlantic Ocean the salmon has a rich cultural heritage based on recreational fishing and its own mystique. Flashing silver as it jumps a 10-foot waterfall, the Atlantic salmon has become a symbol of survival and of healthy river systems.

A world traveler, the wild Atlantic salmon is an anadromous fish - one that spawns in fresh water but spends much of its life at sea. According to the U.S. Endangered Species Act (ESA), the Atlantic salmon is in danger of extinction.

The historic range of the Atlantic salmon included the North Atlantic with freshwater tributaries from Ungava Bay to Lake Ontario and southward to Connecticut in North America, and from Russia's White Sea to Portugal on the European coast.

While many of these salmon runs are now reduced or extinct, Atlantic salmon can still be found in the rivers of Ireland, the United Kingdom, Canada, the Faroe Islands, Iceland, Norway, Sweden, Finland, Russia, France, Spain, Canada and the United States.

Ads Masquerading as Security Warnings


Popup windows are always disturbing, but if you get a warning out of the blue that you might have a security problem it's doubly disturbing. Vendors of what purports to be security software are taking advantage of nervous users to trick them into downloading their software, or at least visiting their Web site.

Ever see a window pop up while you were Web surfing that was filled with dire warnings and big, red exclamation points? It may look like a warning from Windows, but it's just an ad. The ad company may have put a faint "advertisement" notice in the bottom of the box, but the point of the design is to mislead the user into thinking that there is a problem and that clicking "Yes" will help with it.

It turns out that clicking anywhere in this ad, whether on the phony "Yes" or "No" buttons or anywhere else, takes you to the vendor Web site where you can download their product. I am not going to get into whether these products are worth the time of day. The interesting thing is that you can design a popup Web page to resemble a dialog box that a user might encounter if they actually have a Windows problem.

How do you recognize that a window is a popup Web ad and not a message of doom from Windows? This can be difficult. First, even if a window presents a dire message, don't panic. Note that if you look at the title bar and status bar, the top and bottom of the window, you can tell that it is a window created within your browser. This is a clue, but not conclusive proof that the window is not a security warning. It is possible that Windows, or a third party product like your antivirus software, could use such a window for legitimate purposes, but I'd call it a long shot. At this point you can look on the window presumptively as an advertisement.

If you are still curious, right-click on the window and select properties (In Netscape, choose "View Page Info"). You should be able to see the site from which it came. A real dialog box from Windows would have a non-standard address starting with something like 'res:.' A Web ad will have a real web address.

If you maintain and update your antivirus, antispam, and antispyware software, you should not be getting warnings about these programs. If you get warnings about your computer that appear to be real, jot down the information contained in the warning, along with the programs running at the time of the warning. Then, ask someone, who knows computers, about the message or search the Internet.

The important thing for you to do is not to react quickly to messages that come up out of nowhere, but to stop and scrutinize them. At this point you're already ahead of the game.

Ad-Aware Personal Edition


It isn’t enough to protect yourself from viruses, worms, and Trojans. Your system can become bogged down with spyware, adware, and malware. Getting rid of unwanted popup screens and annoying search hijacks requires anti-adware software. In a previous Tutor Tip (Spybot Search and Destroy), I told you about Spybot Search and Destroy, a free program to hunt down spyware on your computer and get rid of it. Spybot works on adware, but no single program can rid you of all adware. The second tool in your arsenal should be Ad-Aware from Lavasoft. You can download the free "personal SE" version of Ad-Aware at http://www.lavasoft.com/support/download/.

Once you have downloaded the program, you can install it easily. Simply follow the on-screen instructions. To run Ad-Aware, double-click the icon on the Desktop or click the Start button and go to All Programs (Programs in Windows 98). Click on Lavasoft Ad-Aware SE Personal and then Ad-Aware SE Personal.

Updating Definitions
When you start Ad-Aware, it will check to see if you are using the latest version of the program and whether your antispyware definitions are up-to-date. Be sure to download the latest version before running a scan. The antispyware definitions are akin to the virus definitions used by your antivirus program and should be updated. If Ad-Aware finds your definitions to be more than 15 days old, it will ask if you would like to check for updates. The answer is yes, so click OK. This procedure will require an Internet connection. If you are not already connected, do so. Then, click the Connect button on the Performing WebUpdate screen. Ad-Aware will inform you when the update is complete.

Note: You can manually update the definitions by clicking the "Check for updates now" link above the program’s Start button or by clicking the globe icon (WebUpdate tool) in the upper right corner of the main screen.

Scanning for Spyware
Click the Start button in the lower right corner of the status screen to begin the scan. On the next screen, you may be asked to select a "Scan Mode." If this is the first time you are running Ad-Aware on your system, select "Perform Full System scan." For most, the smart system scan can be chosen. Make your choice and click Next. This will start the scan, which will take a few minutes to complete.

After the scan is completed, you will be presented with options to "Show Logfile" and to proceed to the "Next" step. Make your selection and, if you choose to view the log, simply use the "back" button to return you to the previous screen. When you click the "next" button you will open the results screen where you can review the objects detected by Ad-aware.

Please be sure to review each item that has been presented in the results screen before removing it. Ad-aware is designed to report possible suspicious content present on your system and to allow you a simple method for removing it should you so decide. Note that Lavasoft does not suggest or recommend that everything detected by Ad-aware should be removed. It is up to you the user to make that determination.

According to Lavasoft, "All items detected by Ad-Aware are qualified using a Threat Assessment Chart (TAC) prior to inclusion. The system is based on a total of 10 points, 1 being the least and 10 being the most threatening and/or problematic. Behavior and intent weigh more heavily towards becoming a legitimate detection than do the technical aspects." You can read more about this in the "Threat Assessment Chart - TAC" section of the Ad-Aware help file. Information about the items Ad-Aware detects can be found in Lavasoft’s TAC database.

What to do with a Detected Item
Every item detected by Ad-Aware will be categorized as either Critical Objects or Negligible Objects. Among the Negligible Objects will be things called "MRUs." MRUs (or MRU Lists) store information about the most recently used items, for example files, search words and programs. MRU Lists are not considered to be a threat to your privacy. Ad-Aware supplies you with the ability to remove these MRU lists if you wish to do so. If you are not sure what to do with an item, quarantine it.

The Negligible Objects list shows the following:

* Obj.: Select objects by ticking the box
* Type: Tells the type of the object
* Description: A brief description of the object
* Location: Tells the location of the object
* No. Items: Tells the number of objects in each MRU List

Critical Objects should be removed, but you can view the list of Critical Objects and determine whether or not to delete them. The list includes the following:

* Obj.: Select objects by ticking the box
* Name: Names the company that developed the object or the target family
* Type: Tells what kind of object it is, such as File, Registry Value, tracking cookie, etc.
* Category: Tells the category in which Lavasoft has it listed, such as Data Miner, Malware, etc.
* Object: Tells where the object is located: its path in Explorer, or its location in the Registry
* Comment: includes the name of the object and a brief description. To read the complete text in the comment scroll to the right side of the screen, open the window full screen, hover your mouse over the entry, or use the right click-context menu.

If you have made the decision to remove an item or multiple items - tick each entry individually or select a single item from the list - right-click with your mouse, and then select the appropriate option from the right-click menu. When you are satisfied with your selections, click the Next button to begin the removal process.

If you have decided to keep an item, select it from the results list (be sure to unselect other content you wish to remove following this step) and right-click the entry to open the right-click menu. Either select each item individually for each component to be ignored or choose the "select all objects" option. Select the "add selection to ignore list" to add this content to your ignore list. Ad-aware will not present this item to you when you perform further scans. Once this content has been added to your ignore lis,t you will be taken back to the scan results screen where you can repeat the above process as required, to not select anything more (all items are unchecked), or to remove the content as you choose.

If you are not certain about an item, you can Quarantine it. Quarantined objects are not deleted from your system, but will not be running on your system, either. You can view and manage quarantined items by clicking the lock icon (Quarantine Manager) on the main status screen. In the Quarantine Manager you can choose to restore the item or permanently delete it.

Ad-Aware should be used to scan your system at least once a week. This will reduce pop-ups and other annoying ads and make your Web surfing experience a more pleasant one.

ActiveX


In a recent Tutor Tip (Is Your Internet Connection Secure?), I recommended that you browse to Symantec’s Security page and check your system for leaks. One of the requirements for the tests to work is having something called ActiveX running in your browser. This elicited several requests for information about ActiveX.

What is ActiveX?
Developed by Microsoft Corporation, ActiveX is a technology used to add interactive controls to Web pages. These controls can be anything from a single push-button to a complete spreadsheet. ActiveX controls only work in certain browsers. Of course, Microsoft's latest release of its own Web browser, Internet Explorer, recognizes ActiveX controls. Netscape's browser does not recognize these controls.

ActiveX is (another) Microsoft strategy for market dominance. Like a lot of Microsoft-centric software, ActiveX is bloated, awkward to use, slow, and has a tendency to make the experience of browsing the Web unpleasant. When encountering some ActiveX controls, browsers often lock up, slow down, freeze, and crash. More seriously, there are security risks inherent in the ActiveX model. ActiveX security rests on the "Authenticode" system which is a scheme for identifying the authors of ActiveX controls. Security is therefore based on trust.

ActiveX controls are only as safe as the company that created them. If a control has a digital signature, it means that the control has not been tampered with and is guaranteed to be exactly the same as when the software publisher created it. The ActiveX controls used by reputable sites are digitally signed by that company. When you see the Security Warning dialog box, check for the statement "Publisher authenticity verified by VeriSign." This statement guarantees that the control has not been tampered with since being signed by the publisher.

How to enable ActiveX in Internet Explorer
The default browser settings in Internet Explorer 5.0 or higher will allow ActiveX controls to download and run. A Medium Security Level allows ActiveX controls to download and run.

1. From the browser menu, click Tools > Internet Options
2. Click on the Security tab
3. Select the globe icon representing the Internet Zone
4. Click Custom Level
5. Scroll down to the ActiveX controls and plug-ins section
6. Under Download signed ActiveX controls select Prompt
7. Under Run ActiveX controls and plug-ins select Enable
8. Under Script ActiveX controls marked safe for scripting select Enable
9. Click OK to close the Security Settings window
10. Click OK to close the Internet Options window

Sir Edmund Hillary and Tenzing Norgay


By today's standards, the 1953 British expedition, under the military-style leadership of Sir John Hunt, was massive in the extreme, but in an oddly bottom-heavy way: 350 porters, 20 Sherpas, and tons of supplies to support a vanguard of only ten climbers. "Our climbers were all chosen as potential summiters," recalls George Band, 73, who was one of the party. Fifty years later, Band's memory of the campaign remains undimmed. "The basic plan was for two summit attempts, each by a pair of climbers, with a possible third assault if necessary. On such expeditions the leader tends to designate the summit pairs quite late during the expedition, when he sees how everybody is performing." Anxiety over who is chosen for the summit team would be a hallmark of major Everest expeditions for decades to come. But never again would the stakes be quite so high.
By the spring of 1953, the ascent of the world's highest mountain was beginning to seem inevitable. First attempted in 1921 by the British, Everest had repulsed at least ten major expeditions and two lunatic solo attempts. With the 1950 discovery of a southern approach to the mountain in newly opened Nepal, and the first ascent of the treacherous Khumbu Icefall the following year, what would come to be known by the 1990s as the "yellow brick road" to the summit had been identified.
At first it seemed the Swiss would claim the prize. In 1952 a strong Swiss team that included legendary alpinist Raymond Lambert had pioneered the route up the steep Lhotse Face and reached the South Col. From that high, broad saddle, Lambert and Sherpa Tenzing Norgay then pushed all the way to 28,210 feet (8,598 meters) on the Southeast Ridge before turning back—probably as high as anyone had ever stood on Earth.
Now the British were determined to bring every possible advantage to their spring 1953 offensive—including hiring Tenzing, 38, as their lead Sherpa, or sirdar. Earlier British expeditions, though impressive in their accomplishments, were often charmingly informal in style. Hunt's intricately planned assault, on the other hand, was all business. "You get there fastest with the mostest," observes mountaineering pundit Ken Wilson. "You have a military leader who is totally in tune with that philosophy, and you don't dink around in an amateur sort of clubby way."

From the start, the 33-year-old beekeeper Edmund Hillary (not yet Sir Edmund) was a strong contender for one of the summit slots. "It was his fourth Himalayan expedition in just over two years and he was at the peak of fitness," Band says. The heavily glaciated peaks of his native New Zealand had proved a perfect training ground for the Himalaya. Hillary earned respect early in the expedition by leading the team that forced a route through the Khumbu Icefall. "A sleeves-rolled-up, get-things-done man," Wilson calls him.
Still, logistical snafus, the failure of a number of stalwarts to acclimatize, and problems with some of the experimental oxygen sets stalled the expedition badly. The team took a troubling 12 days to retrace the Swiss route on the Lhotse Face (in part, perhaps, because the British were not as experienced on difficult ice). In despair, Hunt began to wonder whether his party would even reach the South Col.
The expedition finally gained the col—the vital staging area for a summit push—on May 21. This was late enough to be worrisome, for the monsoon, whose heavy snows would prohibit climbing, could arrive as early as June 1.
Because they became the first men to reach the summit of Everest, Hillary and Tenzing would earn a celebrity that has scarcely faded in 50 years. Who today remembers Tom Bourdillon and Charles Evans? Yet Hunt's plan called for Bourdillon, a former president of the Oxford Mountaineering Club, and Evans, a brain surgeon, to make the first summit bid.
Despite a relatively late start and problems with Evans's oxygen set, Bourdillon and Evans crested the South Summit—at 28,700 feet (8,748 meters), only 330 feet (101 meters) short of the top—by 1 p.m. on May 26. But Evans was exhausted, and both men knew they would run out of oxygen if they went on. They agreed to turn back. Says Michael Westmacott, Bourdillon's closest friend on the 1953 team: "It was a decision Tom always regretted."
So it was that three days later Hillary and Tenzing set out for the top. Their pairing was hardly an accident. "It had always been Hunt's intention, if feasible, to include a Sherpa in one of the summit teams, as a way of recognizing their invaluable contribution to the success of these expeditions," Band says. "Tenzing had already proved he had summit potential by his performance the previous year with Lambert.
In fact, he had been at least 4,000 feet (1,219 meters) higher than any of us!" Indeed, Tenzing (who died in 1986) was the most experienced Everest veteran alive, having participated in six previous attempts on the mountain dating all the way back to 1935. (To those who criticize the practice of leading paying clients on Everest, Himalayan Experience founder and longtime Everest guide Russell Brice has a barbed, half-joking response: "You know who the first guided client on Everest was? Ed Hillary.")
But Hillary, too, had proved his worth, seeming to grow stronger as the expedition progressed. Band notes that Hillary had also realized what a powerful team he and Tenzing would make. "During the expedition, with hindsight, one can see that he made a deliberate effort to develop a good partnership with Tenzing," Band says. "It paid off. Hillary and Tenzing were the logical second party for the summit. But this was not determined at the outset, only during the course of the expedition as it evolved."
With an earlier start from a higher camp than Bourdillon and Evans's, Tenzing and Hillary reached the South Summit by 9 a.m. But the difficulties were far from over. After the South Summit, the ridge takes a slight dip before rising abruptly in a rocky spur some 40 feet (12 meters) high just before the true summit. Scraping at the snow with his ax, Hillary chimneyed between the rock pillar and an adjacent ridge of ice to surmount this daunting obstacle, later to be known as the Hillary Step. The pair reached the highest point on Earth at 11:30 a.m. on May 29.
The men shook hands, as Hillary later wrote, "in good Anglo-Saxon fashion," but then Tenzing clasped his partner in his arms and pounded him on the back. The pair spent only 15 minutes on top. "Inevitably my thoughts turned to Mallory and Irvine," Hillary wrote, referring to the two British climbers who had vanished high on Everest's Northeast Ridge in 1924. "With little hope I looked around for some sign that they had reached the summit, but could see nothing."
As the two men made their way back down, the first climber they met was teammate George Lowe, also a New Zealander. Hillary's legendary greeting: "Well, George, we knocked the bastard off!"
Their fame was spreading even as Hillary and Tenzing left the mountain. "When we came out toward Kathmandu, there was a very strong political feeling, particularly among the Indian and Nepalese press, who very much wanted to be assured that Tenzing was first," Sir Edmund recalls today. "That would indicate that Nepalese and Indian climbers were at least as good as foreign climbers. We felt quite uncomfortable with this at the time. John Hunt, Tenzing, and I had a little meeting. We agreed not to tell who stepped on the summit first.
"To a mountaineer, it's of no great consequence who actually sets foot first. Often the one who puts more into the climb steps back and lets his partner stand on top first." The pair's pact stood until years later, when Tenzing revealed in his autobiography, Tiger of the Snows, that Hillary had in fact preceded him.
Neither man anticipated how much, in the wake of their success, the appeal of that patch of snow more than five miles in the sky would grow. "Both Tenzing and I thought that once we'd climbed the mountain, it was unlikely anyone would ever make another attempt," Sir Edmund admits today. "We couldn't have been more wrong."

Gustave the Croc Surfaces to Strike Again


The last time we went looking for Gustave, Burundi's fabled man-eating crocodile, he was nowhere to be found. It was October 2004, and we'd set out to track down and radio-tag the so-called Monster of Lake Tanganyika, one of the biggest and most bloodthirsty Nile crocs on record ("Have You Seen This Croc?" Adventure, March 2005).
At roughly 20 feet (6 meters) long and approaching 2,000 pounds (907 kilograms), Gustave was reputed to have devoured scores, even hundreds of villagers in the war-weary central African country, picking off victims like some maniacal serial killer. A week before our capture team arrived, Patrice Faye, a self-taught naturalist who has been stalking Gustave since 1998, believed he had spotted him in the estuary of the Rusizi River at the head of the lake. But after leading us on a fruitless search, the expatriate Frenchman gave a Gallic shrug. Maybe rumors of Gustave's demise were true: He'd been shot and eaten by rebels in the neighboring Democratic Republic of the Congo, or had died of old age. Or maybe he'd simply burrowed into the Rusizi's muddy banks to wait out Burundi's protracted Hutu-Tutsi civil war. We left on an uncertain note, with Gustave's mythology fully intact.
In fact, "Gustave is quite alive," Faye told us by telephone on the third anniversary of our aborted mission. "After a long absence he has come back to the Rusizi, and a lot of tourists have had the privilege of seeing him. He's in excellent health, and his prize list of victims has grown."

So, too, has Gustave's international renown. Our story, posted on Adventure's website, has received more hits than any other in the magazine's nine-year history. Web traffic soared after the January 2007 release of Disney's Primeval, a based-on-true-events gorefest starring a cheesy computer-generated giant crocodile named Gustave. Let's not dwell on whose story inspired the screenwriters (we were briefly thrilled when a top studio executive phoned in March 2005 to say that she'd read our article and proposed a deal, which subsequently evaporated in a feeding frenzy of lawyers and producers), but theirs involves a crew of American TV journalists dispatched to "one of the most remote locations on Earth" to hunt down and apprehend "the world's most prolific serial killer." Set in Burundi but filmed in South Africa, the movie, said Faye, "is an insult to purists and herpetologists but, above all, an insult to Burundi.
"It shows the country in a bad light, and the people of Burundi are made out to be savages, barbarians, thieves, and murderers," he told us. "The only good Burundian in the movie ends up being rescued and taken to the United States." The digitized Gustave gallops across the screen like "a champion of cross-country races who devours campsites and cars, climbs trees, and swallows boats," Faye wrote in an indignant letter to Burundi's newspapers. "In short, poor Gustave is a victim of fantasies and becomes more monstrous than ever."
The real-life Gustave is monstrous enough and not nearly as cryptic as we had thought. "I had a pretty clear idea of his movements for the past three years," Faye said. "I have a lot of sources—fishermen, pilots who fly over the lake—and even though I wasn't getting day-to-day information, I knew where he was."
Last spring, for example, Faye received regular reports from the village of Ruziba, just south of Bujumbura, Burundi's capital. At least one fatal attack there could be credibly pinned on Gustave, who apart from his sheer size bears distinctive bullet scars: one on his head, three on his right side.
A croc of similar stature and markings killed a fisherman near Ruziba in April. "He was standing waist-deep in the lake when the croc dragged him away and drowned him," Faye recalled. "There were a lot of witnesses. They raised such a commotion that the crocodile let him go. His widow showed me pictures of the corpse. He had a nasty bite in the stomach and one in the leg." Onlookers chased Gustave away before he could finish his bloody work, Faye said, noting that Gustave doesn't always eat his victims: "I think some of his attacks could just be hunting practice."
During our 2004 mission, the plan was to have herpetologist Brady Barr, the daring host of the National Geographic Channel's Dangerous Encounters, sneak up on Gustave at night in a pirogue, slip a wire noose around his prodigious neck, and wrestle him to shore. After taking measurements and tissue samples, Barr intended to implant a global positioning device beneath Gustave's armored skin that would have alerted villagers to potential danger.
Such warnings might still have gone unheeded, however, because the people who live around the lake depend on it both for life's necessities—food, water, bathing, washing clothes—and for recreation. After Gustave showed up again in the Rusizi, in mid-August, Faye cautioned residents in the nearby village of Gatumba to be on guard. "The fishermen and swimmers didn't interrupt their activities," he said. "It is wishful thinking that people will stay out of the water."
Gustave has yet to snatch anyone from Gatumba, but Faye has no doubt that he is the big croc responsible for these new attacks. When he's not lurking beneath the muddy waters of the Rusizi, fishing and waiting for opportunities for larger prey, he basks on his favorite sandbar, wearing what seems to be a sinister, self-satisfied grin. "I am 100 percent sure it's him," Faye said.
Whether we dust off our plans and head back to Burundi for Operation Gustave, Part Deux, remains to be decided. Barr
has almost fully recovered from massive bite wounds on his thigh, the result of a too-close encounter with a giant python on the Indonesian island of Flores. As this issue went to press, he and his field producers had just completed an expedition to Costa Rica and were digesting the news of Gustave's return.

Political Trends in Eastern Europe


The tutorial will be run as guided independent study projects on topics that are a) related to East Central Europe or the republics of the former Soviet Union, and b) mutually agreed upon by the student and instructor. Once you've chosen a general topic, the goal will be to narrow it down to a more specific question or set of questions or puzzles, and to begin thinking about ways to answer that question. The final paper should clearly address the question, but also consider a number of possible explanations or answers to the question. It should also explain why the answer you've settled on is better than other possible explanations. You should think about the kinds of evidence you're using and the structure of your argument.

Topics are not limited to specific countries. Given the enormous changes in the region over the past 15 years, I'd encourage you to use case studies from the region, either single-country or comparative, to throw light on broader questions. Examples include but are not limited to: the nature of democracy and the process of democratization; the relationship between political and economic changes and structures; questions of culture and politics; questions that address the region's place in the wider global arena, including the impact of outside political and economic forces on politics in the region; the question of citizenship and boundaries.

I see the tutorial as a process in which we journey together from a general topic of interest to trying to answer a specific question. Your grade is thus dependent at least as much on your participation in this process as it is on the final outcome--a 30-40 page research paper. The goal of the tutorial is to familiarize the student with research strategies and methodologies, the use of evidence, as well as wtih the process of structuring and writing a research paper.

Neoliberalism Comes Unglued


By Mark Weisbrot
With the stock market plummeting, an economic and political crisis in Russia, and a regional depression in Asia, a lot of people are wondering if we are staring into the abyss. It's no longer just the left, which has predicted six out of the last three world economic crises, that is nervous. "We are in a situation which is indeed a dangerous one, not fully rational," said IMF managing director Michel Camdessus. And Federal Reserve Board chair Alan Greenspan also warned that "it is just not credible that the United States can remain an oasis of prosperity unaffected by a world that is experiencing greatly increased stress."
The latter statement could be contested. The United States still consumes 88 percent of what it produces, and could, with the right policies, protect its population from adverse economic events in the rest of the world. As much as our political leaders would prefer to let the tail wag the dog--subordinate the domestic economy to the needs of international commerce--they are still a long way from transforming the U.S. economy where our fiscal or monetary policies are externally constrained. The dollar lost a third of its international value between 1985 and 1988, and this had no adverse effect on the U.S. economy. In other words, the Fed could lower interest rates as far as it wanted to, in order to keep the U.S. out of recession. Unlike most other nations, we would not have to worry about the inflationary impact of any currency depreciation that might result. We could also run federal budget deficits, if necessary, for the purpose of maintaining economic growth and employment.
It is important to keep this in mind, not because we are close to having a government that would put the needs of its people ahead of the big bondholders or transnational capital. But they should be held accountable, and not be able to shift the blame to nebulous unseen forces of "the global economy." Greenspan's announcement last week that he would consider lowering interest rates is a positive sign, but it remains to be seen whether the Fed's action will, as has happened in the past, end up being too little and too late.
The events that have dominated the headlines of the economic news are not as interrelated as they appear to be. To get a handle on what is happening, it is worth trying to sort them out a bit.

The Stock Market's Decline

The Dow is down about 16 percent since July 17, and this is commonly attributed to events in Russia and Asia. But this is very misleading. The fact is that stocks were, and still are, grossly overvalued relative to the earnings of the underlying assets they represent. When this happens, decline is inevitable, and the external event that triggers the decline does not "cause" it in any meaningful sense of the word.

It is not that difficult to show that stock prices have been inflated into a speculative bubble. Dean Baker of the Economic Policy Institute has done the necessary arithmetic, in the course of refuting the exaggerated claims--regarding potential stock market returns--made by those who seek to privatize Social Security.

Stock prices can bounce all over the place in the short run, as the market is driven by psychology. But ultimately stocks only have value because the companies they represent earn profits. People forget this sometimes, and then remember it when the market plunges--much as drivers in Washington DC seem to re-learn how to drive in the snow and ice each winter.

There are two sources of income from holding stocks: first, a dividend payout, which represents the shareholder's portion of the companies profits (earnings). The average dividend payout is currently about 2 percent. The other source of income is from an increase in the price of stocks or capital gains. The question is, how much can stock prices increase?

The average price to earnings ratio is still at a record high, even after the recent plunge. So it is safe to assume that prices will not increase faster than earnings. Earnings, however, cannot increase much faster than the growth of the economy--unless we think that there is going to be a continuous redistribution of income from labor to capital. Some of that has happened--the share of national income going to corporate profits has increased by 3.2 percentage points since the last business cycle peak (1989). The typical worker would be earning about $1,100 more annually today if not for that shift. But no one is projecting this trend to continue, and real wages for the majority of the work force have begun to rise significantly during the last two years.

So if stock prices cannot grow faster than earnings, and earnings cannot grow faster than the economy, then we would expect stock prices to grow at about the same rate as the economy. Over the next decade, economic growth is projected to be about 2 percent annually. If we add that to the dividend payout, we get a rate of return on stocks of 4 percent a year, maybe 4.5 percent if the economy grows a little faster.

So why would anyone hold stocks if they can get almost the same return on a short-term bond, with virtually no risk? Well, they might not have seen this arithmetic. If we look at who has done what in the last few market downturns, it has been overwhelmingly the small investors buying and the big players selling. But even for those who know they are sitting on a bubble, there is an enormous temptation to stay in as long you expect others to buy enough to keep driving prices up, so long as you can jump before everyone else does. But that's easier said than done, and of course most people won't be able to pull it off; such is the nature of bubbles, manias, and other excesses of markets generally.

All this analysis shows us is that the stock market's decline is not the result of events in faraway places. It is, however, a truly significant event that might well herald the end of an era in U.S. politics.

Here is the silver lining in the clouds looming over Wall Street: some of the regressive social engineering that took place over the last decade is about to come undone. Certainly the extension of these counter-reforms, in the form of privatizing Social Security, has been dealt a serious blow. The more class-conscious among the privatizers, such as Washington Post columnist James Glassman, have been fully cognizant of the political implications of replacing social insurance--which is not only many times more efficient than any private alternative, but also a solidaristic system with a different ethic--with millions of individual stock holders. They want people to identify with corporate profits, and to have policy makers increasingly constrained from doing anything that might upset the stock market.

The spread of stock ownership to 43 percent of households, many through 401 (k) and other retirement accounts, has coincided with a record run-up in stock prices. To be sure, this ownership is still highly concentrated, with the median household holding only about $14,000 in stocks. In fact, 86 percent of the stock market gains since 1989 have accrued to the top 10 percent of households.

But the idea has been popularized that stocks are the means by which the majority of people partake in the gains from economic growth. That idea will soon be as good as dead. A more sensible alternative can be found in the not-too-distant past, when the majority of Americans shared in the fruits of technological progress through rising wages and an expanding social safety net: e.g. Social Security (which was indexed to inflation in the 1970s), and expanded access to health care (Medicare and Medicaid, long overdue to be extended to the rest of the population). If progressives are able to frame the issue this way, they will likely find a receptive audience, now that the alternative of gambling one's life savings in the stock market has been exposed for what it is--gambling.

Globalization in Crisis

Neoliberalism at the global level has also been dealt some serious blows--although one of the hardest punches has not received the attention it deserves: Russia's default on $200 billion worth of debt, some $40 billion of which is owed to foreigners. Like the proverbial sewer smell arising in the midst of a dinner party, the guests--the international creditors--do not want to mention it. This is a first for the international system of debt peonage, and the idea could easily spread. Mozambique, one of the poorest countries in the world, is paying about a quarter of its export earnings for debt service, more than it spends on education and health care. Other desperately poor countries are similarly squeezed, and the threat of Russia's example is being taken very seriously.

The collapse of the ruble also has implications far beyond Russia's borders. The stabilization of the ruble had been the IMF's only accomplishment over the past six years. The ruble's collapse just weeks after the IMF had put up nearly $5 billion dollars to support it, which went right into the outstretched hands of speculators, has given the Fund another high profile black eye. The IMF's credibility crisis is internationally the most important aspect of neoliberalism's troubles right now, since the IMF is by far the most powerful instrument of transnational capital. Since the Fund inflicts more damage, in economic and human terms, than any other national or international institution, it is worth looking at the current fight over expanding the IMF in the context of the current international economic situation.

The spread of financial and economic turmoil has reminded people that unregulated markets are prone to crises, panics, overshooting, recessions and even depressions. At the level of the nation-state, a number of institutions have evolved which regulate, and sometimes prevent the worst excesses and irrationalities of a market system: even in the United States we have the Federal Reserve as a lender of last resort, Federal deposit insurance, and the automatic stabilizers of government spending, to name just a few examples. At the same time, and sometimes within the same institutions, the welfare state has softened the impact of these irrationalities and also mitigated the injustices that result from market outcomes.

The global economy has no analogous institutions, and transnational capital and its political allies have deliberately expanded its importance (through agreements like NAFTA, the GATT, and the MAI) for the purpose of avoiding the civilizing influences of the last century and a half of struggle. The process has been one of continually removing economic decision making from Parliaments, Congresses, and elected officials, and placing it in the hands of unaccountable institutions such as the IMF, WTO, G-7, etc.

For those who care about the human consequences of these developments, there is a strategic question that is becoming increasingly important: should we accede to the process of increasing global economic integration, and try to create the requisite quasi-state institutions at the international level? Or should we oppose it, with the hope that individual nation states will thus be able, to varying degrees, find their own regulatory mechanisms--whether they be national-developmentalist, social democratic, or even socialist?

In some cases it might be possible to do both--e.g., oppose the process and simultaneously fight for labor rights clauses in new international agreements. But in other cases our choices are much more limited, and it is crucial that we understand this limited range of choice.

The IMF is one such case, and the lack of clarity among the progressive community is hurting us. The recent troubles have amplified the voices of those among our elite who would support some greater international regulatory mechanisms--the U.S. Treasury Department calls it a "new architecture of the global economy." While not all of the measures they would consider are harmful, the expansion of the IMF's power that they propose would be an enormous step backward.

Many people who would ordinarily oppose economic colonialism are willing to acquiesce to, or even support the expansion of the IMF in the hope that it may someday be transformed into its opposite. This is a terrible mistake. The IMF is a brutal, colonial institution, controlled by Washington, an organizer of creditors that squeezes the world's poorest countries for debt service on loans they cannot ever hope to repay. It is also a de-regulatory institution, whose adopted mission is to open up the world's economies to transnational capital on the latter's terms. It has consistently wielded its enormous power against any industrial or even agricultural strategy that has been centered around national economic development. With the exception of the Mexican peso crisis, it has never functioned as a lender of last resort, as its recent failures in Indonesia and Russia have amply demonstrated.

This is not a question of reform versus abolition, as it is often posed. The IMF will indeed change its policies in response to criticism--as even dictators like Suharto did. In fact, it already has, allowing Indonesia to increase its budget deficit target from 1 percent to 8.5 percent of GDP. But it will not be reformed into anything that can have a net positive impact, if for no other reason than it is unaccountable to any population anywhere. And it will not be abolished any time soon.

The idea that we can create international institutions, controlled by the governments of the world's richest countries, that would somehow reverse the policies that these governments are pursuing, has always seemed far-fetched to me. It would make more sense to first change the foreign economic policy of the United States, where at least we can vote, before expanding its power over the poorer countries of the world.

The need for clarity on these questions is important, as the Clinton administration is asking for $18.5 billion to expand the IMF's capital base by 45 percent (with the contributions of other members, who will likely follow the U.S. lead). With every tremor in the international economy, as well as the stock market, the Administration has exhorted Congress to approve the money or risk being blamed for the next disaster. Most Democrats have gone along from the beginning, with only a handful--along with the large majority of Republicans--holding it up. After the latest IMF-sponsored fiasco in Russia, House Appropriations chair Bob Livingston, the Administration's key Republican ally, announced he was reconsidering his support, and Newt Gingrich made similar noises.

Neoliberalism will of course survive with a much weakened and discredited IMF, but its backers are aware how much more difficult it is to force countries like South Korea to accept mass layoffs or remove its remaining controls on foreign capital and ownership, as the IMF has recently arranged, if the orders were coming directly from Washington or a handful of private foreign banks. The neoliberals understand the importance of this battle; unfortunately, many on our side do not.

Cracks in the Wall

It is understandable that many people could be carried away by the prospect of global economic reform. There has been a significant shift in the public debate over the last year, and even the last few months. A number of prominent, pro-globalization, mainstream economists have come out in favor of increased capital controls. Joseph Stiglitz, chief economist of the World Bank and former chair of President Clinton's Council of Economic Advisors, breached protocol by openly accusing the IMF of exacerbating the Asian financial crisis. Columbia University's Jagdish Bhagwhati, one of the world's most prominent international economists and the Economic Policy Adviser to the Director-General of GATT (1991-93), has noted that "the Asian crisis cannot be separated from the excessive borrowings of foreign short-term capital as Asian economies loosened up their capital account controls and enabled their banks and firms to borrow abroad. . . it has become apparent that crises attendant on capital mobility cannot be ignored." Jeffrey Sachs and Steve Radelet of the Harvard Institute of International Development have reached similar conclusions in some well-researched papers on the Asian financial crisis, and Sachs has had some harsh words for the IMF, calling it "the Typhoid Mary of emerging markets, spreading recessions in country after country." The most radical break with neoclassical orthodoxy has come from no less a champion of globalization than Paul Krugman, who, writing in a recent article for Fortune magazine, proposed a return to restrictions on the convertibility of currencies. The latter policy was promptly adopted by Malaysia last week.

These epiphanies by prominent economists are long overdue, and recent events have provided an opportunity to blurt out the obvious. China has notably been the least affected by the Asian crisis, and certain reasons for its relative immunity seem clear: their currency is not convertible, they have little foreign ownership in financial markets, and their banking system is government-owned. Being free from IMF orthodoxy has its advantages: in response to the crisis, China announced last March a three year, $1 trillion public works program (the equivalent in the U.S., if you can imagine it, would be more than $8.5 trillion). How much and how it is actually implemented remains to be seen, but any expansionary policy makes a lot more sense than the beggar-thy-neighbor process of trying to export your unemployment by means of an undervalued currency--the latter is a zero-sum game.

Krugman's policy of foreign exchange controls makes sense, too, and Russia appears to be the next candidate for adopting it, unless the IMF can stop them. Look at the alternative: Mexico is jacking up interest rates to 38 percent in order to stem the capital flight, currency collapse, resultant inflation, and possible economic disaster that has threatened them because of…Russia--country that has nothing to do with them. The irrationality of international financial markets has reached new extremes, as one poor country after another is trampled by the herd behavior of investors who may know nothing more than the fact that other investors might be averse to "emerging markets" after the last disaster.

The human cost of this irrationality has been staggering, especially in Asia. Years of economic and social progress are being negated, as the unemployed vie for jobs in sweatshops that they would have previously rejected, and the rural poor subsist on leaves, bark, and insects. In Indonesia, the majority of families now have a monthly income less than the amount that they would need to buy a subsistence quantity of rice, and nearly 100 million people--half the population--are being pushed below the poverty line. Women have been particularly hard hit: they are first to be laid off, have taken sharper cuts in access to food and other necessities, and girls are being pulled from school to help with their families' survival.

How much of this misery is directly due to neoliberal policies and their supporting institutions? It appears to be quite a bit. The short-term debt build-up that preceded the Asian financial crisis clearly created the instability that turned the fall of the Thai baht in July 1997 into a regional financial meltdown. This rapid accumulation of short-term debt, in turn, was a direct result of the removal of capital controls--at the insistence of the United States. For example, South Korean, Thai, and Indonesian banks (as well as non-financial corporations) were allowed, in the last six years, to borrow from international markets with fewer restrictions then ever before. Since the burden of foreign debt service increases when the domestic currency falls, this left these economies extremely vulnerable to a panic, and the ensuing vicious spiral of currency depreciation.

What was needed at the onset of the crisis was a supply of foreign exchange reserves to assure investors that they did not have to flee the country today in order to avoid further foreign exchange losses tomorrow. The government of Japan actually proposed, at a meeting of regional finance ministers in September 1997, that an Asian Monetary Fund be created in order to provide liquidity to the faltering economies, and with fewer of the conditions imposed by the IMF. This fund was to have been endowed with as much as $100 billion in emergency resources, which would come not only from Japan, but from China, Taiwan, Hong Kong, Singapore, and other countries, all of whom supported the proposal.

After strenuous opposition from the U.S. Treasury Department, which insisted that the IMF must determine the conditions of any bailout before any other funds were committed, the plan was dropped by November. It is impossible to tell how things might have turned out differently, but it is certainly conceivable that not only the depression, but even the worst of the currency collapses could have been avoided if the fund had been assembled and deployed quickly at that time.

The IMF then failed to provide the necessary reserves--Indonesia had received only $3 billion by March 1998. Even worse, the IMF's insistence on very high interest rates, as well as fiscal austerity, worsened the contraction of the injured economies. The result was that a liquidity crisis, which could have been managed and limited to the financial sphere of the economy, became a major regional depression.

Less noticed has been Washington's contribution to Russia's economic disaster. Most Americans are unaware of it, but the Russian economy had already collapsed long before the recent unhinging of the ruble and default on government debt. Over the last six years, American economists--together with the International Monetary Fund--have presided over one of the worst economic declines in modern history.

Russian output has declined by more than 40 percent since 1992--a catastrophe worse than our own Great Depression. Millions of workers are not being paid and most economic transactions now take place through barter. The majority of the population has fallen into poverty. Death rates have risen sharply and the decline in male life expectancy--from a pre-reform 65.5 years to 57 years today--is unprecedented in peacetime, in the absence of a natural disaster. All of this happened before the current meltdown.

The failures of neoliberalism are getting harder to ignore, even for its defenders. Its global component had already suffered a significant defeat last year, as the president's quest for fast-track authority--to negotiate new trade and commercial agreements without amendments from Congress--was blocked. Opposition to IMF expansion has also thrown a wrench in their machinery. The Multilateral Agreement on Investment, a treaty that would extend the investment provisions of NAFTA to the 29 mostly high-income countries of the OECD (Organization for Economic Co-operation and Development), and then to the rest of the world, has also been slowed down by worldwide opposition.

Nonetheless we are only beginning to crack the structure of neoliberal ideology in the United States. Although the debate within the economics profession has received a bit of coverage in the Wall Street Journal and the New York Times, most reporting--whether through print or electronic media--remains unaffected by it. The airwaves are saturated with blather about "crony capitalism" as the cause of Asia's troubles, and we are daily reminded that Russia needs to be forced to follow the West's "reform" program more diligently. Unlike the stock market, which directly affects some millions of people's lives and forces them to think about their future, foreign economic policy remains in the mystified realm of the experts and officials. The foreign policy establishment has made no concessions, and is not planning to make any. The Clinton administration is forging ahead with plans to complete the MAI negotiations this fall.

Washington is a still a long way from changing its course, but its ability to impose its neoliberal dogma on the rest of the world is waning. And that, by itself, is cause for hope.
