Animal Minds: Parrot Alex

A In 1977 Irene Pepperberg, a recent graduate of Harvard University, did something very bold. At a time when animals still were considered automatons, she set out to find what was on another creature’s mind by talking to it. She brought a one-year-old African gray parrot she named Alex into her lab to teach him to reproduce the sounds of the English language. “I thought if he learned to communicate, I could ask him questions about how he sees the world.”

B When Pepperberg began her dialogue with Alex, who died last September at the age of 31, many scientists believed animals were incapable of any thought. They were simply machines, robots programmed to react to stimuli but lacking the ability to think or feel.Any pet owner would disagree. We see the love in our dogs’ eyes and know that, of course, they has thoughts and emotions. But such claims remain highly controversial. Gut instinct is not science, and it is all too easy to project human thoughts and feelings onto another creature. How, then, does a scientist prove that an animal is capable of thinking – that it is able to acquire information about the world and act on it? “That’s why I started my studies withAlex,” Pepperberg said. They were seated – she at her desk, he on top of his cage – in her lab, a windowless room about the size of a boxcar, at Brandeis University. Newspapers lined the floor; baskets of bright toys were stacked on the shelves. They were clearly a team – and because of their work, the notion that animals can think is no longer so fanciful.

C Certain skills are considered key signs of higher mental abilities: good memory, a grasp of grammar and symbols, self-awareness, understanding others’ motives, imitating others, and being creative. Bit by bit, in ingenious experiments, researchers have documented these talents in other species, gradually chipping away at what we thought made human beings distinctive while offering a glimpse of where our own abilities came from. Scrub jays know that other jays are thieves and that stashed food can spoil; sheep can recognize faces; chimpanzees use a variety of tools to probe termite mounds and even use weapons to hunt small mammals; dolphins can imitate human postures; the archerfish, which stuns insects with a sudden blast of water, can learn how to aim its squirt simply by watching an experienced fish perform the task.AndAlex the parrot turned out to be a surprisingly good talker.

D Thirty years after the Alex studies began; Pepperberg and a changing collection of assistants were still giving him English lessons. The humans, along with two younger parrots, also served as Alex’s flock, providing the social input all parrots crave. Like any flock, this one – as small as it was – had its share of drama. Alex dominated his fellow parrots, acted huffy at times around Pepperberg, tolerated the other female humans, and fell to pieces over a male assistant who dropped by for a visit. Pepperberg bought Alex in a Chicago pet store where she let the store’s assistant pick him out because she didn’t want other scientists saying later that she’d particularly chosen an especially smart bird for her work. Given that Alex’s brain was the size of a shelled walnut, most researchers thought Pepperberg’s interspecies communication study would be futile.

E “Some people actually called me crazy for trying this,” she said. “Scientists thought that chimpanzees were better subjects, although, of course, chimps can’t speak.” Chimpanzees, bonobos, and gorillas have been taught to use sign language and symbols to communicate with us, often with impressive results. The bonobo Kanzi, for instance, carries his symbol-communication board with him so he can “talk” to his human researchers, and he has invented combinations of symbols to express his thoughts. Nevertheless, this is not the same thing as having an animal look up at you, open his mouth, and speak. Under Pepperberg’s patient tutelage, Alex learned how to use his vocal tract to imitate almost one hundred English words, including the sounds for various foods, although he calls an apple a “beanery.” “Apples taste a little bit like bananas to him, and they look a little bit like cherries, Alex made up that word for them,” Pepperberg said.

F It sounded a bit mad, the idea of a bird having lessons to practice, and willingly doing it. But after listening to and observing Alex, it was difficult to argue with Pepperberg’s explanation for his behaviors. She wasn’t handing him treats for the repetitious work or rapping him on the claws to make him say the sounds. “He has to hear the words over and over before he can correctly imitate them,” Pepperberg said, after pronouncing “seven” for Alex a good dozen times in a row. “I’m not trying to see if Alex can learn a human language,” she added. “That’s never been the point. My plan always was to use his imitative skills to get a better understanding of avian cognition.”

G In other words, because Alex was able to produce a close approximation of the sounds of some English words, Pepperberg could ask him questions about a bird’s basic understanding of the world. She couldn’t ask him what he was thinking about, but she could ask him about his knowledge of numbers, shapes, and colors. To demonstrate, Pepperberg carried Alex on her arm to a tall wooden perch in the middle of the room. She then retrieved a green key and a small green cup from a basket on a shelf. She held up the two items to Alex’s eye. “What’s same?” she asked. Without hesitation, Alex’s beak opened: “Co-lor.” “What’s different?” Pepperberg asked. “Shape,” Alex said. His voice had the digitized sound of a cartoon character. Since parrots lack lips (another reason it was difficult for Alex to pronounce some sounds, such as ba), the words seemed to come from the air around him, as if a ventriloquist were speaking. But the words – and what can only be called the thoughts – were entirely his.

H For the next 20 minutes, Alex ran through his tests, distinguishing colors, shapes, sizes, and materials (wool versus wood versus metal). He did some simple arithmetic, such as counting the yellow toy blocks among a pile of mixed hues. And, then, as if to offer final proof of the mind inside his bird’s brain, Alex spoke up. “Talk clearly!” he commanded, when one of the younger birds Pepperberg was also teaching talked with wrong pronunciation. “Talk clearly!” “Don’t be a smart aleck,” Pepperberg said, shaking her head at him. “He knows all this, and he gets bored, so he interrupts the others, or he gives the wrong answer just to be obstinate. At this stage, he’s like a teenager; he’s moody, and I’m never sure what he’ll do.”

Developing Courtiers

A The Ecotourism Society defines ecotourism as “a responsible travel to natural areas which conserves the environment and improves the welfare of local people”. It is recognised as being particularly conducive to enriching and enhancing the standing of tourism, on the basis that this form of tourism respects the natural heritage and local populations and are in keeping with the carrying capacity of the sites.

B Cuba is undoubtedly an obvious site for ecotourism, with its picturesque beaches, underwater beauty, countryside landscapes, and ecological reserves. An educated population and improved infrastructure of roads and communications adds to the mix. In the Caribbean region, Cuba is now the second most popular tourist destination. Ecotourism is also seen as an environmental education opportunity to heighten both visitors’ and residents’ awareness of environmental and conservation issues, and even to inspire conservation action. Ecotourism has also been credited with promoting peace, by providing opportunities for educational and cultural exchange. Tourists’ safety and health are guaranteed. Raul Castro, brother of the Cuban president, started this initiative to rescue the Cuban tradition of herbal medicine and provide natural medicines for its healthcare system. The school at Las Terrazas Eco-Tourism Community teaches herbal healthcare and children learn not only how to use medicinal herbs, but also to grow them in the school garden for teas, tinctures, ointments and creams. In Cuba, ecotourism has the potential to alleviate poverty by bringing money into the economy and creating jobs. In addition to the environmental impacts of these efforts, the area works on developing community employment opportunities for locals, in conjunction with ecotourism.

C In terms of South America, it might be the place which shows the shortcoming of ecotourism. Histoplasma capsulatum, a dimorphic fungus, is the most common endemic mycosis in the United States, and is associated with exposure to bat or bird droppings. Most recently, outbreaks have been reported in healthy travelers who returned from Central and South America after engaging in recreational activities associated with spelunking, adventure tourism, and ecotourism. It is quite often to see tourists neglected sanitation while travelling. After engaging in high-risk activities, boots should be hosed off and clothing placed in airtight plastic bags for laundering. HIV-infected travelers should avoid risky behaviors or environments, such as exploring caves, particularly those that contain bat droppings.

D Nowhere is the keen eye and intimate knowledge of ecotourism is more amidst this fantastic biodiversity, as we explore remote realms rich in wildlife rather than a nature adventure. A sustainable tour is significant for ecotourism, one in which we can grow hand in hand with nature and our community, respecting everything that makes us privileged. Travelers get great joy from every step that take forward on this endless but exciting journey towards sustainability. The primary threats to South America’s tropical forests are deforestation caused by agricultural expansion, cattle ranching, fagging, oil extraction and spills, mining, illegal coca farming, and colonization initiatives. Deforestation has shrunk territories belonging to indigenous peoples and wiped out more than 90% of the population. Many are taking leading roles in sustainable tourism even as they introduce protected regions to more travelers.

E In East Africa, significantly reducing such illegal hunting and allowing wildlife populations to recover would allow the generation of significant economic benefits through trophy hunting and potentially ecotourism. “Illegal hunting is an extremely inefficient use of wildlife resources because it fails to capture the value of wildlife achievable through alternative forms of use such as trophy hunting and ecotourism,” said Peter Lindsey, author of the new study. Most residents believed that ecotourism could solve this circumstance. They have passion for local community empowerment, loves photography and writes to laud current local conservation efforts, create environmental awareness and promote ecotourism.

F In Indonesia, ecotourism started to become an important concept from 1995, in order to strengthen the domestic travelling movement, the local government targeting the right markets is a prerequisite for successful ecotourism. The market segment for Indonesian ecotourism consists of: (i) “The silent generation”, 55-64 year-old people who are wealthy enough, generally well-educated and have no dependent children, and can travel for four weeks; (ii) “The baby boom generation”, junior successful executives aged 35-54 years, who are likely to be travelling with their family and children (spending 2-3 weeks on travel) – travelling for them is a stress reliever; and (iii) the “X generation”, aged 18-29 years, who love to do ecotours as backpackers – they are generally students who can travel for 3-12 months with monthly expenditure of US$300-500. It is suggested that promotion of Indonesian ecotourism products should aim to reach these various cohorts of tourists. The country welcomes diverse levels of travelers.

G On the other hand, ecotourism provide as many services as traditional tourism. Nestled between Mexico, Guatemala and the Caribbean Sea is the country of Belize. It is the wonderful place for Hamanasi honeymoon, bottle of champagne upon arrival, three meals daily, a private service on one night of your stay and a choice of adventures depending on the length of your stay. It also offers six-night and seven-night honeymoon packages. A variety of specially tailored tours, including the Brimstone Hill Fortress, and a trip to a neighboring island. Guided tours include rainforest, volcano and off-road plantation tours. Gregory Pereira, an extremely knowledgeable and outgoing hiking and tour guide, says the following about his tours: “All of our tours on St. Kitts include transportation by specially modified Land Rovers, a picnic of island pastries and local fruit, fresh tropical juices, CSR, a qualified island guide and a full liability insurance coverage for participants.

H Kodai is an ultimate splendor spot for those who love being close to mother nature. They say every bird must sing its own throat while we say every traveller should find his own way out of variegated and unblemished paths of deep valleys and steep mountains. The cheese factory here exports great quantity of cheese to various countries across the globe. It is located in the center of forest. Many travelers are attracted by the delicious cheese. The ecotourism is very famous of this different eating experience.

Soviet’s New Working Week

“There are no fortresses that Bolsheviks cannot storm”. With these words, Stalin expressed the dynamic self-confidence of the Soviet Union’s Five Year Plan: weak and backward Russia was to turn overnight into a powerful modern industrial country. Between 1928 and 1932, production of coal, iron and steel increased at a fantastic rate, and new industrial cities sprang up, along with the world’s biggest dam. Everyone’s life was affected, as collectivised farming drove millions from the land to swell the industrial proletariat. Private enterprise disappeared in city and country, leaving the State supreme under the dictatorship of Stalin. Unlimited enthusiasm was the mood of the day, with the Communists believing that iron will and hard-working manpower alone would bring about a new world.

Enthusiasm spread to time itself, in the desire to make the state a huge efficient machine, where not a moment would be wasted, especially in the workplace. Lenin had already been intrigued by the ideas of the American Frederick Winslow Taylor (1856-1915), whose time-motion studies had discovered ways of stream-lining effort so that every worker could produce the maximum. The Bolsheviks were also great admirers of Henry Ford’s assembly line mass production and of his Fordson tractors that were imported by the thousands. The engineers who came with them to train their users helped spread what became a real cult of Ford. Emulating and surpassing such capitalist models formed part of the training of the new Soviet Man, a heroic figure whose unlimited capacity for work would benefit everyone in the dynamic new society. All this culminated in the Plan, which has been characterized as the triumph of the machine, where workers would become supremely efficient robot-like creatures.

Yet this was Communism whose goals had always included improving the lives of the proletariat. One major step in that direction was the sudden announcement in 1927 that reduced the working day from eight to seven hours. In January 1929, all Indus-tries were ordered to adopt the shorter day by the end of the Plan. Workers were also to have an extra hour off on the eve of Sundays and holidays. Typically though, the state took away more than it gave, for this was part of a scheme to increase production by establishing a three-shift system. This meant that the factories were open day and night and that many had to work at highly undesirable hours.

Hardly had that policy been announced, though, then Yuri Larin, who had been a close associate of Lenin and architect of his radical economic policy, came up with an idea for even greater efficiency. Workers were free and plants were closed on Sundays. Why not abolish that wasted day by instituting a continuous workweek so that the machines could operate to their full capacity every day of the week? When Larin presented his ides to the Congress of Soviets in May 1929, no one paid much attention. Soon after, though, he got the ear of Stalin, who approved. Suddenly, in June, the Soviet press was filled with articles praising the new scheme. In August, the Council of Peoples’ Commissars ordered that the continuous workweek be brought into immediate effect, during the height of enthusiasm for the Plan, whose goals the new schedule seemed guaranteed to forward.

The idea seemed simple enough but turned out to be very complicated in practice. Obviously, the workers couldn’t be made to work seven days a week, nor should their total work hours be increased. The solution was ingenious: a new five-day week would have the workers on the job for four days, with the fifth day free; holidays would be reduced from ten to five, and the extra hour off on the eve of rest days would be abolished. Staggering the rest-days between groups of workers meant that each worker would spend the same number of hours on the job, but the factories would be working a full 360 days a year instead of 300. The 360 divided neatly into 72 five-day weeks. Workers in each establishment (at first factories, then stores and offices) were divided into five groups, each assigned a colour which appeared on the new Uninterrupted Work Week calendars distributed all over the country. Colour-coding was a valuable mnemonic device since workers might have trouble remembering what their day off was going to be, for it would change every week. A glance at the colour on the calendar would reveal the free day, and allow workers to plan their activities. This system, however, did not apply to construction or seasonal occupations, which followed a six-day week, or to factories or mines which had to close regularly for maintenance: they also had a six-day week, whether interrupted (with the same day off for everyone) or continuous. In all cases, though, Sunday was treated like any other day.

Official propaganda touted the material and cultural benefits of the new scheme. Workers would get more rest; production and employment would increase (for more workers would be needed to keep the factories running continuously); the standard of living would improve. Leisure time would be more rationally employed, for cultural activities (theatre, clubs, sports) would no longer have to be crammed into a weekend, but could flourish every day, with their facilities far less crowded. Shopping would be easier for the same reasons. Ignorance and superstition, as represented by organized religion, would suffer a mortal blow, since 80 per cent of the workers would be on the job on any given Sunday. The only objection concerned the family, where normally more than one member was working: well, the Soviets insisted, the narrow family was har less important than the vast common good and besides, arrangements could be made for husband and wife to share a common schedule. In fact, the regime had long wanted to weaken or sideline the two greatest potential threats to its total dominance: organised religion and the nuclear family. Religion succumbed, but the family, as even Stalin finally had to admit, proved much more resistant.

The continuous work week, hailed as a Utopia where time itself was conquered and the sluggish Sunday abolished forever, spread like an epidemic. According to official figures, 63 per cent of industrial workers were so employed by April 1930; in June, all industry was ordered to convert during the next year. The fad reached its peak in October when it affected 73 per cent of workers. In fact, many managers simply claimed that their factories had gone over to the new week, without actually applying it. Conforming to the demands of the Plan was important; practical matters could wait. By then, though, problems were becoming obvious. Most serious (though never officially admitted), the workers hated it. Coordination of family schedules was virtually impossible and usually ignored, so husbands and wives only saw each other before or after work; rest days were empty without any loved ones to share them – even friends were likely to be on a different schedule. Confusion reigned: the new plan was introduced haphazardly, with some factories operating five-, six- and seven-day weeks at the same time, and the workers often not getting their rest days at all.

The Soviet government might have ignored all that (It didn’t depend on public approval), but the new week was far from having the vaunted effect on production. With the complicated rotation system, the work teams necessarily found themselves doing different kinds of work in successive weeks. Machines, no longer consistently in the hands of people how knew how to tend them, were often poorly maintained or even broken. Workers lost a sense of responsibility for the special tasks they had normally performed.

As a result, the new week started to lose ground. Stalin’s speech of June 1931, which criticised the “depersonalised labor” its too hasty application had brought, marked the beginning of the end. In November, the government ordered the widespread adoption of the six-day week, which had its own calendar, with regular breaks on the 6th, 12th, 18th, 24th, and 30th, with Sunday usually as a working day. By July 1935, only 26 per cent of workers still followed the continuous schedule, and the six-day week was soon on its way out. Finally, in 1940, as part of the general reversion to more traditional methods, both the continuous five-day week and the novel six-day week were abandoned, and Sunday returned as the universal day of rest. A bold but typically ill-conceived experiment was at an end.
