The genera Escherichia is thought to have emerged around 102 million years ago and is known as a gram-negative pathogenic bacteria mostly found in the intestines of warm blooded animals [1]. German pediatrician and bacteriologist Theodor Escherich discovered E. coli in 1885, and for many years the bacterium was simply considered to be a commensal organism of the large intestine. It was not until 1935 that a strain of E. coli was shown to be the cause of an outbreak of diarrhea among infants [2]. The reason its pathogenic properties were discovered so late is that many of its strains are harmless. However, virulent strains of E. coli can cause various diseases in humans and in domestic animals, and are also sometimes responsible for product recalls due to contamination. Gastroenteritis, urinary tract infections, and neonatal meningitis are the most commonly observed diseases in humans, and in rare cases virulent strains are also responsible for haemolytic-uremic syndrome, peritonitis, mastitis, septicaemia and Gram-negative pneumonia [2]. Various outbreaks all around the world have been caused by E. coli, causing millions of deaths and sick people and billions of dollars have been spent fighting it. Even though death rates have decreased with the evolution of modern medicine and the discovery of antibiotics, the outbreaks are still a major concern for all countries, such as the recent outbreak in Germany in 2011 affecting 3,950 people and killing 53 [3].

Its reputation has not been one of great dignity, and it has ruined the reputation of many. You may recall in 1993, the fast food chain restaurant “Jack in the Box” suffered a major corporate crisis involving E. coli O157:H7 bacteria. Four children died of hemolytic uremic syndrome and 600 others were reported sick after eating undercooked patties contaminated with fecal material containing the bacteria at locations in Seattle and the Pacific Northwest, USA. The chain was faced with several lawsuits, each of which was quickly settled but left the chain nearly bankrupt and losing customers.

But don’t these creatures have any properties to be appreciated, I wonder…

Compared to eukaryotic cells, bacteria have a pretty basic mechanism of functioning. They don’t have sophisticated organelles, and they do not have a cell nucleus where their DNA is stored. Everything is floating along all together in the cell cytoplasm (which shocks me when I reflect upon how such a small and simple organism can cause such severe pain on “highly evolved modern humanity”). It has the basic metabolic tools for survival. And even though, at first sight, it is tempting to look down on its simplicity, today we know that it is this simplicity that gives us space for making many modifications and experiments on it, whereas in more complicated cells, like animal cells, the moment a modification is made, the entire system reacts to that and causes much trouble in the process.

The turning point of E.coli making a huge impact on our lives was in 1973, when Stanley Cohen and Herbert Boyer discovered the “Recombinant DNA Technology.” This technology allowed specific genes to be isolated from one organism and cloned to another organism by the help of bacterial plasmids. The first commercial product to be synthesized by this technology was human insulin, which is used for the treatment of diabetes [4]. This brought an amazing amount of recognition and appreciation for the technology, as the practical aspect of the technology was now proven to be commercially profitable. For the insulin to be produced, the DNA sequence that encodes human insulin was synthesized and transplanted into a plasmid that could be maintained in a non-pathogenic strain of E.coli [4]. Now the bacterial host cells acted as biological factories for the production of the two peptide chains of human insulin, which, after being combined, could be purified and used to treat diabetics who were allergic to the commercially available porcine (pig) insulin, or for diabetics from certain religious groups who abstain from pork products such as Muslims, Jews, some Christian groups, and many more who have similar concerns.

This was only the start of an incredible new technology which used bacteria to produce different proteins or enzymes to cure human diseases. Today more than 200 new drugs have been produced by recombinant DNA technology and have been used to treat over 300 million people for diseases such as cancer, multiple sclerosis, cystic fibrosis, and stroke, and to provide protection from other infectious diseases. Over 400 new drugs are in the process of being tested in human trials to treat such diseases as Alzheimer disease and heart disease (to name only two) [4].

Today E.coli is frequently used as a model organism for all kinds of microbiological experiments. In the lab, E. Coli. is one of the first micro-organisms that is thought of for testing a biological experiment. The reason is that E.coli cells are cheap to purchase and to sustain. They grow easily and rapidly in lab conditions and have non-pathogenic strains, so they are not dangerous for the researches doing the experiment. Whereas purchasing more complicated cells such as cancer cells or stem cells may be very costly, and moreover, may need special lab conditions to be sustained; so before more complicated cells are purchased, the experiments are usually tried out with E.coli or some other kind of model organism. More importantly, E. coli was one of the first organisms to have its genome sequenced; the complete genome of E. coli K12 was published by Science in 1997 [5]. Other areas in which modified E.coli has helped humanity are vaccine development, bioremediation (fighting pollution), and production of immobilised enzymes [6].

One specific example of the benefit of recombinant DNA technology for the environment is its use in the paper industry. Before the 1970’s, when there wasn’t much environmental awareness in the paper producing industry, poisonous chlorine compounds were conventionally used to achieve pulp brightness of a high order in the manufacture of high-quality paper products [7]. This chemical bleaching technique precipitated a tremendous environmental concern considering the magnitude of the industry. Plants treated with elemental chlorine produced significant amounts of dioxins. Dioxins are highly toxic, and their health effects on humans include reproductive, developmental, immune and hormonal problems. They are also known to be carcinogenic. Over 90% of human exposure is through food, primarily meat, dairy, fish and shellfish, as dioxins accumulate in the food chain in the fatty tissue of animals [7]. One alternative for these chemical bleaching processes is the use of the enzyme “xylanase,” which degrades the linear polysaccharide beta-1,4-xylan into xylose, thus breaking down hemicellulose, one of the major components of plant cell walls. Even though the use of xylanases in this industry has increased significantly with the discovery of Viikarri et al. (1986), the enzyme needs further improvements for it to be commercially acceptable [6]. To ensure the commercial utilization of hemicellulosic residues in the pulp and paper industries, the production of higher xylanase yields at low capital cost is required [6]. Such studies are ongoing with the purpose of partially mutating the amino acid sequence for the purpose of especially increasing the thermal stability of the enzyme and also increasing its metabolic activity. The gene mutation and gene expressions are generally done in either E.coli or yeast cells. Davoodi et al. has mutated the enzyme up to the point where the transition temperature increased 12 0C by introducing disulfate bonds in the enzyme [8]. The wonders this enzyme can do for the health of the environment is breathtaking, and is an area which should be further studied until finding the commercially viable kind that will eliminate chemicals from the paper industry during bleaching.

Even though some controversy remains on gene transferring, its tremendous positive impact on humanity cannot be denied. I personally think that it does need constraints and strict regulations, but this technique is one of the most remarkable techniques discovered in modern times, and E.coli has no doubt played a great role in the availability of this technology.

Even though condemning E.coli and stating its “evilness” seems like the most obvious path, we all ought to appreciate the variety and uniqueness of these creatures which also allow us to produce such large varieties of drugs. We ought to appreciate its simplicity, which allows it to have a chance of producing such sophistication. We ought to reflect upon the fact that something can be classified as “good” or “bad” only by the means in which we perceive it, and the reality of it may be completely opposite of what we had thought initially.

Although this industry had been an effective instrument for advertising and increasing political and social efficiency, the wide screen is being used for different purposes. In contrast with earlier films, which were dominated by guns, money, and status and also promoted authority, individualism, adventure-seeking, and atheism, the last 5 years have seen movies highlight something else: material gain should not be the ultimate purpose, the necessity of unity and cooperation, and life after death. This reflects the severely deteriorated structure of the American family and wondering how it can be restored.

Movies with social themes

Family themes. In The Kid (2000), Bruce Willis plays a workaholic who long ago forgot his past and family and refuses to see his father. Then one day his childhood appears before his eyes in the form of himself as a child. Thanks to this event, he makes peace with his past and gradually regains his lost values. This movie is one of many recent movies depicting weakened family ties: a lack of spousal love, children leaving home at earlier ages and forgetting their families, and elderly parents being left unprotected by their children.

In The Family Man (2000), Nicholas Cage is a passionate businessman desperate to achieve as high a status as possible. He does not know that real pleasure can be found in a lovely wife and children. One day, he wakes up and finds himself married with two children. As fictitious as it is, he cannot realize how his life changed all of a sudden, but later realizes real happiness with his new family. The first thing he does after this so-close-to-real dream is to search for the woman he is going to marry.

American Beauty, which won the Oscar in 1999, made its way through many other big-budget movies. Spousal mistrust and the widening generation gap were the main topic in this movie, and the fact it won The Best Picture award shows the importance given to the concept of family.

Life after death themes. Life after death also has been a popular theme. The Sixth Sense (1990), a nominee for The Best Picture award in 1999, features a child who sees dead people walking around like regular people. They have an explicit message: The universe is more than what we can perceive through our five senses. In Ghost (1990), Patrick Swayze is a dead person whose soul is still in touch with this world and his beloved wife, whom he tries to protect from danger. What Dreams May Come (1998) takes Robin Williams into Heaven and Hell so he can meet his wife and children again. Gladiator (2000), awarded five Oscars including The Best Picture award, is the story of the Maximus, commander-in-chief of the Roman army, who is willing to leave behind status and fame so that he can reunite with his family for happiness. He is an invincible ” but praying ” commander, who teaches his soldiers about what comes after death, and tragically reaches his family at the end.

Angels and the Devil. Angels and the Devil also are frequent topics. City of Angels (1998) is a good example. Meg Ryan is a person who can exercise free will, taste worldly pleasures, and is expected to know God, whereas Nicholas Cage is an angel who lives in a different dimension and has none of these abilities. Likewise, Brad Pitt portrays the angel of death in Meet Joe Black (1998) and shows us a fictional perspective through an angel’s eyes.

In the digitally remastered and remixed version of The Exorcist (2000), a family tries to reclaim their possessed teenage daughter through every possible medical treatment. In the end, however, two priests are called to exorcise the demon. In The Devil’s Advocate (1997), Al Pacino portrays the Devil, who seeks to control people with lust, status, and money. Keanu Reeves portrays a very successful lawyer who has never lost a trial. He finds himself in a struggle between the Devil’s intrigues and his human virtues.

In End of Days (1999), Arnold Schwarzenegger is an ex-cop who believes in the brute power of muscles and weapons. However, he comes to realize that conventional methods of combat do not work on Beelzebub (the Devil), and so has to devise other solutions. Throwing away his machine gun, he kneels at the altar and prays for help.

Destiny. Destiny is another hot topic. Destiny is a significant part of the belief that keeps societies up and strong. Such a belief lets us know that everything comes from God, which gives us the strength to bear life’s difficulties. Almost 100 years ago, speculation that a comet might hit Earth scared many people who did not believe in destiny. Final Destination is about a group of young people who attempt, but fail, to challenge the destiny that is chasing them. The Green Mile and Fight Club are also good examples for movies with metaphysical content that show that life is not all that we can see.

Religion. Christianity is being questioned in Hollywood movies. In Stigmata (1999), during the 1940s some scripts ” supposedly the original New Testament scriptures from Jesus’ time ” written in ancient Aramaic on leather pieces are found rolled in several jars. They are sent to Rome, after which nothing is heard about them. In the meantime, Frankie, a young girl in her twenties, is attacked brutally by an unseen assailant. She consults doctors and psychiatrists, but nobody can help her. The only man who can help is Andrew Kiernan (Gabriel Byrne), an investigator sent by the Vatican to stop demons from taking over her life.

Bless the Child (2000) tells about a child with supernatural powers. Her evil occultist mom and stepfather want to take her back from her aunt who raised her. The girl talks with her stepfather just like Jesus talked with the Devil, as recorded in the Bible. Her aunt tries to save her from a Biblical prophecy, and in the end angels help them out. In Dracula (2000), people realize that they can defeat Dracula’s supernatural powers only by seeking help from God.

Hollywood also has become interested in other religions. Several movies have been made about Buddhist Tibet and the Dalai Lama. Islam, despite its close and popular association with terrorism in the minds of many, has appeared in a few movies with some positive images. For example, Antonio Banderas played a Muslim envoy (Ahmad Ibn Fadlan) from Amawis in the 13th Warrior (1999), who was an educated and refined person. In Robin Hood (1991), during the Fourth Crusade Kevin Costner brought with him back to England a scholarly Muslim who was admired by the English because he could use binoculars and gunpowder.

Conclusion

These movies inspire us with a promising future, as materialism appears to be less popular and people are interested in searching for the soul, the Hereafter, brotherhood and sisterhood, peace, and love. We can only hope that this trend will continue.

Interfaith Network: The United Communities of Spirit is a global interfaith network linking people of diverse faiths and beliefs who want to work with others to build a better world. In its quest to promote awareness that all people belong to the same spiritual family, it offers e-mail/web conference facilities and an extensive database that allows members to express the fine details of their personal beliefs. – http://origin.org/ucs.cfm.

Ecological Medicine: As more people realize that health and environment are interlinked, interest in ecological medicine continues to increase. Kenny Ausubel’s “The Coming Age of Ecological Medicine” (The Utne Reader, 27 July 2001) deals with this topic. In it, Carolyn Raffensperger, executive director of the Science and Environmental Health Network (SEHN), says that ecological medicine seeks to establish the conditions for health and wholeness, acknowledges that people are part of the local ecosystem, and that medical practices should not damage other species or the ecosystem. SEHN calls upon science and industry to conduct impact studies before implementing their activities. Raffensperger claims that this usually is not done, and that the results are disastrous. – www.utne.com.

The “Benefits” of Smoking: Philip Morris reports that deaths from smoking saved the Czech government at least $30 million on health care, pensions, and housing for the elderly; that smoking had a positive effect on the nation’s 1999 public finance balance (estimated at $146 million); and that smoking-related expenses of $394 million (1999) were “almost exactly balanced out by the excise duty charged by the Czech government.” Moreover, the government benefited from value added tax of $89 million, customs duty of $9 million, and income tax from tobacco businesses in the Czech Republic of $19 million. Spokesman Remi Calvet said that: “We deeply regret any impression that premature death of smokers could represent a benefit for society. Tobacco is a controversial industry, but we are still an industry and sometimes we need some economic data on our industry.” – http://washingtonpost.com.

IN SCIENCE

Free Space Optics: Researchers are studying the possibility of replacing underground cabling with free space optics, a system that uses invisible focused lasers to transmit data. Speeds of up to 1 gigabit per second, faster than any other broadband connection now available, are possible. Several problems remain to be solved, though: automatic refocusing of laser connections, ensuring a clear line of sight, and how to deal with fog and other weather conditions that could disrupt the signal. Terabeam reports successful trials in foggy Seattle. – www.popsci.com.

The “God” Particle: Europe’s CERN laboratory and the Fermi National Accelerator Laboratory near Chicago are racing to find evidence supporting the Higgs boson, a subatomic particle popularly known as the “God” particle. Researchers at CERN thought that they had found it in November 2000, but now it appears that these “may have been simply random movements by other, less interesting particles.” The Higgs boson is a theoretical particle believed to be the source of mass and weight in the uni- verse. The race continues. – www.latimes.com.

A More Accurate Clock: American scientists using sophisticated laser technology and a cooled ion of the liquid metal mercury (a mercury atom with one electron stripped off) have developed the “all-optical atomic clock.” In theory, it could be as much as 100 to 1,000 times more accurate than current cesium-based microwave atomic clocks. Applications are expected in navigation and communications technology, as well in such abstract areas as Einstein’s theory of general relativity and the plasticity of time. – http://news.cnet.com.

Stem Cell Research: A National Institutes of Health report calls for more research on how adult, fetus, and embryo stem cells can help treat juvenile diabetes, Parkinson’s, and other diseases. Stem cells from days-old embryos, most of which are obtained from fertility clinics, seem to show the most potential. They are more plentiful, easier to extract and then grow and multiply in a laboratory, and can develop into a much wider array of tissues. Opponents are trying to block research on the grounds that such cells constitute potential or actual human life. – http://washingtonpost.com.

But what happens when an ideological regime dedicated to negating existing realities to build utopia takes over? A small clique of Cambodian French-educated intellectuals provides the answer by a term coined specifically to describe it: auto-genocide. How else can a regime whose vision caused an estimated 800,000 to 2.3 million “unnatural” deaths among an estimated 5.7 million people within 3.5 years be described?(1)

Before and after April 17, 1975

Building Trust: Independent Cambodia was led by Prince Sihanouk (1941-70), whom the vast majority of Cambodians regarded as semi-divine: “In general the majority of the Khmer people, particulary the peasants, loved the Prince … From the law of Kamma [karma] and reincarnation, Khner commoners believed that those who were born as kings, princes and princesses were beings descended from heaven [because of the good deeds they had] performed in previous existences … Prince Sihanouk was thus looked upon as a ‘super being’ who controlled the fate of all.”(2)

Rejecting the traditional “splendid isolation” of the Cambodian monarchy, Sihanouk travelled the country, met and talked with all types of people, donated farm equipment and other helpful things, and sought to solve their problems. In short, the people trusted him because he took the trouble to show he cared about them.

When General Lon Nol overthrew Sihanouk on March 18, 1970 (with presumed American help) and abolished the monarchy, many peasants sensed disaster ahead.(3) They were right. Lon Nol was corrupt, had little grasp of Cambodia’s military situation, and was mentally weakened by a stroke in 1971.(4) His military campaigns were disastrous, his dictatorial tendencies encouraged many to join the Khmer Rouge, and he gradually seemed to lose touch with reality. As a result, he rapidly lost whatever popular trust he had and was “asked” to leave Cambodia on April 1, 1975.

Upon assuming control on April 17, 1975, the Khmer Rouge presented Angka Leou (the Organization) as their public face. Their names were announced on April 14, 1976, but their use of false names and lack of biographical information made exact identification impossible.(5) For 2 years, they did not mention that they were communists who envisaged a socialist future. Nor did they explain their new policies to the nation.(6) Their isolation from the people was complete.

Instead of building trust, the Khmer Rouge sought to destroy ever pillar of traditional society. The family structure was shattered by forced evacuations from cities and continual arbitrary population shifts, gender- and aged-based work brigades, and communal eating. Roles were reversed: children were encouraged to report on their parents, indoctrinated instead of educated, and literally given the power of life and death over adults. Religion was outlawed; temples, mosques, and churches were destroyed or converted into other uses; and monks, imams, and priests were murdered. No public manifestation of religion was allowed. In its Utopian zeal, the Khmer Rouge outlawed everything that made Cambodia what it was.

In return they gave illusion, terror, pain, and lies. An internal Khmer Rouge document states that: “There is a little friction with the people, but we can abandon the people, there is no problem.”(7) The Khmer Rouge was concerned only mobilizing its people through ideology and discipline to retake southern Vietnam and protect itself against Vietnam. Along with many other Utopians, the ends justified the means.

Rational Economic and Development Policies: The French colonialists kept the peasantry largely rural and subjected to high taxes and usurious interest rates of as much as 200%. Rubber, corn, and rice were the main products, and industry was minimal. Vietnamese were important in fishing, rubber workers, and clerical workers, fishermen, and small business. The Chinese continued to dominate commerce and banking.(8)

With independence, foreign aid projects were regarded as means of personal enrichment.(9) Sihanouk’s paternalistic doctrine of Royalist-Buddhist Socialism stated that the ruler would provide for the people. With the elite and others becoming richer and able to travel abroad, conspicuous consumption increased even though the nation’s economy could no longer expand, for there had not been enough time to construct the needed infrastructures.(10) The countryside remained largely the same, while the urban areas consumed and did not produce.

Under Lon Nol, agriculture was wiped out by relentless US bombing, peasant flight, forced induction into various armies, and the destruction of land and draft animals. Industry was ignored, and aid money was siphoned off into people’s pockets. When Phnom Penh finally fell in 1975, Cambodia had no economy, agricultural or industrial, to speak of.

The Khmer Rouge immediately emptied the cities.(11) This controversial policy forced everyone into the countryside where, divided into “old people” and “new people,” they were expected to revitalize agriculture. Ideology, instead of analysis or rational thought, determined who would do what. Production quotas were wildly unrealistic in many areas. Most of what was produced was confiscated or bartered for Chinese products and expertise. Payment was a subsistence diet, and not even that for anyone who failed to reach the quota.

After printing a new currency, the Khmer Rouge decided to scrap it and abolish money altogether, for whereas money created markets, wealth, and private property, abolishing it would solve these “problems.”(12) Trade with China, the Khmer Rouge’s only significant ally, was based on barter. But money never totally disappeared. Along with jewelry and gold, money was used in black market transactions, and Khmer Rouge cadres were not immune.(13)

In a land with no agricultural, industrial, or educational infrastructure to speak of, the Khmer Rouge dared to dream of achieving a “Super Great Leap Forward”: “We have leaped Over the semi-colonial, semi-feudal society of the American imperialists, the feudalists and capitalists of every nation, and have achieved a socialist state straight away.”(14) Chou En-lai, Chairman Mao’s right-hand man, urged them not to repeat China’s own Great Leap Forward, but they thought they knew better.

The Khmer Rouge stated that Cambodia as a whole would modernize its agriculture within 10 to 15 years, while other areas would do so in only 4 or 5 years.(15) Agriculture would make everything possible: “The basic key is agriculture. Self-reliance means capital from agriculture.”(16) Recognizing their limitations in industry, Party documents of 1976-77 stressed light industry that would move toward heavy industry. But how was this to be carried out? Cambodia had no money and China was changing: the chaos of the Great Proletarian Cultural Revolution (1966-76) had weakened China and Mao was dead (Sept. 9,1976). In addition the Gang of Four, a group of staunch Khmer Rouge patrons consisting of Mao’s wife and three of her allies, was under arrest (Oct. 6, 1976).

Control over the Nation’s Territory: On April 17, 1975, the Khmer Rouge controlled all of Cambodia’s territory. But this was not good enough-Pol Pot dreamed of restoring the old Khmer Empire, which had ruled much of southern Vietnam and still had a large ethnically Khmer population (Khmer Rrom). By mixing this irredentist desire with Cambodians’ traditional fear of Vietnam, Pol Pot unleashed a conflict that only a Utopian divorced from reality could understand. During April 1977, the Khmer Rouge began attacking villages in Vietnam. On January 1, 1978, the Khmer Rouge publicly announced Vietnam’s “aggression,” and full-scale war erupted.

This war was launched for several reasons:

•They had defeated American alone and so were invincible. On July 22, 1975, Pol Pot stated:”We have won total, definitive, and clean victory, meaning that we have won it without any foreign connection or involvement.”(17) Such a deliberate ignoring of history led him to change the date of the Communist Party of Kampuchea’s founding 1951 (an outgrowth of Ho Chi Minh’s Indochina Communist Party) to 1960, when he became the party’s deputy secretary, and to begin purging Cambodian communists trained in Vietnam.

•Cambodia needed “only 2 million troops to crush the 50 million Vietnamese.”(18) This ignored the facts that Vietnam had militarily defeated both the French and Americans and had a battle-hardened army with decades of actual military experience and plenty of weaponry. Compared to them, the Khmer Rouge army was a murderous joke.

•The general population would support them, despite official policies of destroying everything held dear by them, execution as practically the only punishment, starvation, overwork, and a lack of military training and supplies.

This bellicosity led to Vietnam invading Cambodia on December 25, 1978, occupying it on January 7, 1979, and staying until September 1989.

An Educated Population: After decades of French colonial rule that had seen fit to keep Cambodians ignorant, Sihanouk embarked on a massive campaign to educate young Cambodians. However, apparently neither he nor the people understood that education should serve the nation. The students and their parents saw it as a means to acquire social status, an escape from village life, and a chance to make money. The liberal arts and a bureaucratic career were preferred over careers in agriculture, any technical field, or industry. Finally, the government and the educational sectors could no longer absorb the graduates. Neither could the economy, which was controlled by the Cambodian aristocracy and elite, and Chinese and Vietnamese merchants. Thus, the intellectuals were largely irrelevant to Cambodia’s development needs, unemployed, and frustrated.(19)

The Khmer Rouge did not trust intellectuals, regardless of how useful their expertise might be. There are many cases of Cambodian intellectuals returning from abroad only to be executed. Former teachers, professionals, and students soon learned to deny their past and merge into the broad uneducated masses.

In most areas, formal education was abolished in favor of learning by doing and ideological indoctrination. Khieu Samphan, Cambodia’s nominal head of state, displayed this attitude in 1977: “… whether the dams and reservoirs thai we have built last only 5 or 10 years does not matter,” for the people would learn by doing…; a year later he admitted that the state of pharmaceutical products was ‘still of handicraft quality’ in order that the country remain independent, sovereignty, self-reliant, and self-sufficient, and in order to learn technology through practice.”(20) Clearly, modern technical and other education was irrelevant-only ideological purity mattered.

Conclusion

The Khmer Rouge failed because they refused to understand Cambodia’s reality: a small nation devastated by war; a society consisting of a mainly poor, uneducated, and illiterate peasantry; a class of intellectuals whose education was largely irrelevant; and two neighbors with far better armies and historical territorial ambitions on Cambodia (Thailand and Vietnam).

They also failed to understand their own people. With their oft-repeated maxim of “If you die it is no loss; if you live it is no gain,” how could it be otherwise? The Khmer Rouge were notorious for their purges, which became ever more bloody as their Utopian dreams could not overcome reality. After replacing the old sociely with a new one based on terror, incompetence, an almost total lack of medical care, starvation, murder, and basically forcing its people to live in Hell before they died, the Khmer Rouge nevertheless expected popular support-because their ideology mandated it. But as the purges gathered steam, many Khmer Rouge began defecting to Vietnam to join nascent armed opposition groups being trained by Vietnam, and many ordinary Cambodians lost whatever revolutionary enthusiasm they might have had.(21)

And what was the end of Pol Pot, the mastermind behind this negative Utopia? Forced to rely for his very survival on America, France, and Thailand, he and his forces were confined to gradually smaller and smaller border areas. When he died in 1998, whether naturally or a suicide is not certain, be was “cremated under a pile of rubbish and rubber tires.”(22) His replacement was Ta Mok, a man whose name has become a synonym for brutality and violence. After arresting and trying his former leader, Ta Mok eulogized him as follows: “He (Pol Pot) is nothing more than cow dung. Actually, cow dung is more useful.”(23)

The movie makers probably did not intend to make killing look attractive. But was it the final effect anyways? Do movies depicting indecent acts fail to show the consequences sufficiently? What can society do about this trend? These and similar questions have been asked and debated for decades. Below, we analyze a time in Hollywood when the concentrated efforts of concerned individuals and organizations had a significant positive impact on forcing the movie industry to move toward self-regulation.

The Beginning of the Movie Industry

Movies rose as a new form of entertainment at the turn of twentieth century. By the 1920s, 40 million Americans were watching them each week. After winning the right to vote in 1920, flapper girls were exercising their new-found freedom, Harlem nightclubs flourished with whites with an interest in African American culture, and the number of gangs selling liquor during Prohibition increased. Movie producers displayed these value changes in their films to attract more young people. This started the big fight between America’s moral guardians and the movie makers.

Hollywood scandals in the early 1920s accelerated the demand for movie censorship. In 1921, the famous comedian Fatty Arbuckle was accused of raping and murdering a young actress; director William Desmond Taylor was found murdered, and a series of front page stories revealed his drug use and sex life; actor Wallace Reid died of a drug overdose; and America’s “sweetheart,” Mary Pickford, got a quick divorce to marry Douglas Fairbanks.

The motion picture business had become an industry. Film companies seeking to integrate production, distribution, and exhibition had one formula in mind: expansion meant capital, capital meant Wall Street, and Wall Street meant conservative business practices. They could not afford any scandals or federal investigations of Hollywood.

The Pressure for Codes Builds

Leff and Simmons write: “In 1921 alone, solons in thirty-seven states introduced nearly one hundred bills designed to censor motion pictures. Women could not smoke on screen in Kansas but could in Ohio; a pregnant woman could not appear on screen in Pennsylvania but could in New York. Six censorship states, which controlled over thirty percent of the theater seats in America, condemned illegitimacy and sexual deviance.”(1) State censors recut films after the producers, and the outcome was unfavorable. Local exhibitors were tired of the cost of censor cuts and attacks by the public and the media. In January 1922, the movie company presidents formed a trade association, the Motion Picture Producers and Distributers of America (MPPDA). Postmaster General Will Hays, an ex-Republican national chairman with White House connections, was chosen as their head. He was a great success as a spokesperson, but failed as a censor regulator of movie content.

Under Hays, Hollywood instituted a morals clause that, as part of the standard employment contract, regulated performers’ off-screen lives: “The artist agrees to conduct himself with due regard to public conventions and morals and agrees that he will not do or commit any act or thing that will tend to degrade him in society or bring him into public hatred, contempt, scorn or ridicule, or that will tend to shock, insult or offend the community or ridicule public morals or decency or prejudice the producer or the motion picture industry in general.”(2) Furious with such self-regulation and restraints, many ignored the contract, and so the scandals continued.

A mainly Protestant anti-movie lobby grew larger and more threatening in the mid-1920s. The Women’s Christian Temperance Union (WCTU), the Reverand William H. Short’s Motion Picture Research Council, and Canon William Shaefe Chase’s Federal Motion Picture Council, among others, all lobbied for federal action. Supporters of cencorship bills claimed that movies were immoral, vile, and corrupting young people. With the advent of —talking— films, the moral guardians of America faced a bigger threat: movies were more popular and dialogue challenged public norms. According to Black: —In 1928 the New York State censorship board cut over 4,000 scenes from more than 600 films submitted, and Chicago censors sliced more than 600 scenes.—(3) Martin Quigley, owner and publisher of the industry trade journal Exhibitors Herald-World, initiated in 1929 the first attempt by Catholics to influence the film industry. Believing that government censorship was futile, he began thinking of a code that would include rules, regulations, and philosophy. Father FitzGeorge Dinneen, Chicago censor board advisor, sent him to Father Daniel Lord, a St. Louis University professor who could write the document. The resulting production code had three working principles:

• No picture should lower the moral standards of those who see it.

• Law, natural or divine, must not belittled, ridiculed, nor must a sentiment be created against it.

• As far as possible, life should not be misrepresented, at least not in such a way as to place in the mind of youth false values of life.(4)

The production code termed movies entertainment, and those who made them were obligated to produce —correct entertainment— for mass audiences. Movies had a profound impact on the —bodies and souls of human beings,— and could —affect spiritual and moral progress.— Hays saw the code in early 1930. He later wrote: —My eyes nearly popped out when I read it. This was the very thing I had been looking for.—(5) The code announced specific limitations on language and behavior. Lots of offensive words and phrases were banned, and the ridicule of religion, nudity, evocative dances, depiction of illegal drug use, and scenes of childbirth were prohibited. The code was explicit when it came to on-screen crime and sex:

I. Crimes against the Law

These shall never be presented in such a way as to throw sympathy with the crime as against law and justice or to inspire others with a desire for imitation.

1. Murder

1. The technique of murder must be presented in a way that will not inspire imitation
2.  Brutal killings are not to be presented in detail c. Revenge in modern times shall not be justified

2. Methods of crime should not be explicitly presented

1. Theft, robbery, safe cracking, and dynamiting of trains, mines, buildings, etc., should not be detailed in method
2. Arson must be subject to the same safeguards
3. The use of firearms should be restricted to essentials d. Methods of smuggling should not be presented

3. Illegal drug traffic must never be presented a. The use of liquor in American life, when not required by the plot or for proper characterization, will not be shown.

II. Sex

The sanctity of the institution of marriage and the home shall be upheld. Pictures shall not interfere that low forms of sex relationship are the accepted or common thing. 1. Adultery, sometimes necessary plot material, must not be explicitly treated, or justified, or presented attractively. 2. Scenes of Passion a. They should not be introduced when not essential to the plot. b. Excessive and lustful kissing, lustful embraces, suggestive postures and gestures, are not to be shown. c. In general passion should so be treated that these scenes do not simulate the lower and baser element.(6) Interestingly, the above principles set forth by a Catholic scholar were in perfect accord with the moral codes of Islam, another Abrahamic religion that prohibits the vivid depiction of actions not approved by God.(7) By the beginning of the Depression, film studios turned increasingly to themes of sex and violence to attract audiences. Finally, Hays used the resulting public reaction to persuade the studios that enforcing the code would be the most secure and economical answer to their troubles. If the movie industry regulated itself, it could prevent likely government intervention. The film companies were in debt, having spent a lot of money to introduce sound, and many had lost money in the stock market crash of 1929. Desperate to cut costs, they decided to avoid paying to revise the film after the censorship boards made their edits, by following the code before making their movies. The code was adopted in 1930.

Joe Breen Gets Involved

During 1930-34, movie producers ignored and openly mocked the code. The pressure continued from the Catholic Church with the support from Jewish and Protestant leaders. In 1934 Joe Breen, a strict Catholic moralist working as a public relations man for the production code in Hay’s office, was hired to run Hollywood’s Production Code Administration (PCA). Breen brought new standards: —The PCA had the authority to review all movies and demand script changes. Any theater that ran a film without the PCA seal of approval would be fined $25,000.—(8) Finally the Code had some power. Studios accepted it and produced films that met Breen’s standards. Largely because of his efforts to get the code implemented, it has become known as Breen’s Code. It lasted for more than two decades, being officially abandoned only in 1968. Breen’s Code is a perfect example of people affecting the behavior of institutions whose motives may not match the best interests of the people they serve. By expressing their dissatisfaction and organizing to pressure the motion picture industry, Americans managed to change the nature of the movie industry’s products toward higher moral standards held in common by most monotheistic religions. As we go into the twenty-first century, there are many areas in which people of faith can work together to make a positive change in their societies and the world

Since the mid-1980s, there has been increasing interest in developing so-called “electronic noses” (e-noses), that is, electronic instruments that can detect and recognize simple and complex odors.1 And since the mid-1990s, nearly 20 years after the concept was originally published, the commercialization of e-noses has started to take place. The main reasons for this delay were the complex nature of the problem and the need for advanced technologies. However, the recent development of microsensor technology has led to low-cost integrated chemical sensors and application-specific microprocessing devices. This, coupled with our greater understanding of artificial intelligence, has allowed us to construct electronic instruments that perform in a manner similar to our own olfactory system.

E-noses are now being developed as systems for the automated detection and classification of odors, vapors, and gases. They are generally composed of a chemical sensing system (e.g., sensor array or spectrometer) and a pattern recognition system, such as an artificial neural network (ANN). At Pacific Northwest National Laboratory (PNNL), e-noses use ANN technology for the automated identification of volatile chemicals used in environmental and medical applications.2

The electronic nose works as follows. While a chemical vapor or odor is blown over a sensor array, sensor signals are digitized and fed into a computer. The ANN (implemented in software) then identifies the chemical. The benefits of e-noses include compactness, portability, real-time analysis, and automation.

FOOD INDUSTRY APPLICATIONS

Currently, the largest market for e-noses is the food industry. In some instances, e-noses can augment or replace panels of human experts and can reduce the amount of analytical chemistry performed in food production, especially when only qualitative results will do.

An electronic smelling device is a valuable tool for analyzing whether a product has gone bad. Potential applications of e-noses in the food industry are numerous: inspecting and grading food quality by odor; inspecting fish and beverage containers; controlling fermentation, automated flavoring, and microwave cooking; monitoring the ripening of cheese; verifying if orange juice is natural and/or fresh; testing plastic wrap for containing the odor of onions; and classifying grains and blueberry ripeness.

Using human odor panels to evaluate and control the quality of raw materials or finished products is extremely labor intensive, time consuming, expensive, and error prone. E-noses can quickly identify a characteristic odor classified as “good” or “bad” by the odor panel, thereby decreasing the workload, improving throughput, and reducing the cost of screening many samples at different stages of the manufacturing process. The system is applied easily to the manufacture and quality control of perfumes, cosmetics, and fine chemicals, as well as to packaging, monitoring environmental quality, the automotive industry, medical and diagnostic matters, and microbial classification.

ENVIRONMENTAL MONITORING

The PNNL is exploring the technologies required to perform cost-effective environmental restoration and waste management. This effort includes developing portable, inexpensive systems that can identify contaminants in the field in real time. Environmental applications of e-noses include identifying toxic wastes and household odors; analyzing fuel mixtures; detecting oil leaks; monitoring air quality, factory emissions, and hazardous chemicals; and testing ground water for odors.

MEDICAL APPLICATIONS

Since the sense of smell is important for physicians, an e-nose can be used as a diagnostic tool to examine bodily odors (e.g., breath, wounds, bodily fluids, etc.) and identify possible problems. Odors in the breath can indicate gastrointestinal, sinus, and liver problems, as well as infections and diabetes. Infected wounds and tissues emit distinctive odors, and odors coming from such bodily fluids as blood and urine can indicate liver and bladder problems. Currently, an e-nose for examining wound-related infections is being tested at South Manchester University Hospital.

In similar applications, ANNs have been used to track glucose levels in diabetics, determine ion levels in bodily fluids, and detect such pathological conditions as tuberculosis.

While the inclusion of visual, aural, and tactile senses into telepresent systems is widespread, the sense of smell has been largely ignored. PNNL recently proposed a more futuristic application of e-noses for telesurgery. In this application, an e-nose would identify odors in a remote surgical environment. These identified odors then would be transmitted electronically to another site, where an odor generation system would recreate them.

The next decade should see the cost of e-noses fall dramatically, with the result that they will be used not only in industry but also in everyday life. They can be used, for example, to detect tainted foods in the refrigerator, ensure clean clothes in the washing machine, detect poor air quality in the car, and perhaps even help us monitor our own health.

The word ‘robot’ was first used in the 1922 play R.U.R. by the Czech playwright Karel Capek: the title is an acronym for Rossum’s Universal Robots which become so sophisticated that they take over the world. ‘Robot’ is compounded from the Czech words ‘robota’ or work, and ‘robotnik’ or serf (Capek. 1923).

The use of industrial robots, first clearly identified in the 1960s, along with computer aided design (CAD) and computed aided manufacturing (CAM) systems, characterizes the latest trends in the automation of the manufacturing process (Roth, 1983). These technologies arc leading industrial automation through another transition, the scope of which is still unknown.

Growth of the robotics market has slowed compared to the early 1980s. The use of industrial robots is at present concentrated in rather simple, repetitive tasks which do not to require high precision. However, manufacturing market analysis predicts that early next century industrial robots will become increasingly viable in applications which require more precision and sensory sophistication such as assembly tasks. The automotive industry, where robots have been economically justified since the 1970s, will continue to be the leading user. However, the major growth of the US robot population will occur in non-automotive industries.

2. Robot classes and characteristics

Robots can be classified in many ways. To establish a generic classification system, we shall refer to dimensions or degrees of freedom or DOF.

The DOF of a mechanical system refers to the number of physical axes through which motion can occur. In robotics, DOF can often be equated with the number of joints in the robot.

Typical present-day industrial robots have from one to six-DOF, although more are certainly possible. For example, a wrist can be made more flexible by adding rotation to the twisting already in that joint. Similarly, a fourth DOF can be added to the shoulder, where the arm joins the base to allow additional rotation of the arm. Industrial robots are also classified by the mechanical configuration of the individual elements of the arm and actuators. Theses classifications are: rectangular class (X,Y,Z): cylindrical class (R,?,Z): spherical class (R,?,?); and jointed class (?1,?1,?). This classification begins with simple movements in a rectangular co-ordinate system such as the x-y co-ordinate system.

3. World’s robot population

More than 610.000 industrial robots are now at work according to a new annual publication by the secretariat of the United Nations Economic Commission for Europe (UN/ECE) and the International Federation of Robotics (IFR).

The world’s robot population grew by about 6% in 1993 compared with 8% the year before. These growth rates fall significantly short of those of 16-23% recorded in the booming late 1980s and early 1990s. However, in view of the deep recession which commenced at the end of 1990 in robot-using countries and resulted in large reductions in investment and industrial employment, growth in the robot stock of 6%-8% is still quite impressive. 

Japan accounts for more than half of the world robot stock. However, the net increase in Japanese robot stock fell sharply in both 1992 and 1993. In 1993, the net increase in the robot stock was only about a third of the record year 1990, underscoring the depth of the Japanese recession.

With 325 robots for every 10.000 persons employed in manufacturing, Japan has by far the world’s highest robot density followed by Singapore with 109, Sweden with 73, Italy with 70 and Germany with 62. As a result of falling employment in the manufacturing industry in 1992-1993, robot density increased rapidly in many countries even though the robot stock increased only modestly.

In most countries, welding is the predominant application area for robots, particularly for major motor vehicle producing countries, accounting for more than 20% of the total robot stock. In a few countries machining was the largest application area. Assembly was the largest application area in Japan, accounting for 40% of the total stock of robots. It is worth noting that in Japan assembly accounted for 50% of the net increase in stock while welding only had a share of 9%.After a solid recovery in 1994, the robot market is forecast to boom in the period up to 1998. Based on macroeconomics forecast of the development of world economics the UN/ECE and IFR forecast that the world stock of industrial robots will increase from some 610,000 units at the end of 1993 to over 830.000 units at the end of 1997. As the number of personnel employed in industry is falling, the density of robots measured as the number of robots per 10.000 workers will continue to surge. In terms of units, shipments are estimated to increase from about 54.000 units in 1993 to over 103,000 units in 1997.

While the robot market was expected to be somewhat hesitant in Japan in 1994 and 1995, it was expected to boom in the United States, Western Europe and the dynamic Asian economies. If growth and world trade gain momentum as predicted from 1995, the prospects for the robotics business seem extremely bright.

The potential for expansion of robotics is enormous. If other industrialized countries were to approach the robot densities of Japan and if industry in general were to reach only half the robot density of the motor vehicle sector, the robot stock would increase manifold, and this is not counting the potential for robots in the service industries. The following example gives an illustration of the potential: if industry in France and the United Kingdom were to achieve a robot density half that of the motor vehicle industry in those countries, the robot stock would more than double; if it reached half the density of the Japanese motor vehicle industry, the robot stock in those countries would increase more than 20 times.

4. Summary

The emphasis in this article has been on industrial robots and techniques currently used in that environment. The future of robotics depends on improvements in many technologies to reduce cost and increase the range of performance so that robots become effective in more environments. These technologies include motors, actuators, contact sensors, non contact sensors, mechanisms, lubrication, electronics, computers and artificial intelligence.
