I saw Barbara Ehrenreich as being a positive speaker who had her ups and down as she was growing up. One of the things she mentions was her opinion on under age drinking. She felt like college students are the ones who get targeted the most when it comes to drinking she felt like it shouldn’t be no legal age on drinking and that she didn’t see any problems with it. Than she talks about how hard it was for single parents on welfare to make it in the society with vary low income. She felt like if the CEO married single women in the lower and middle class that the women would not have it so bad on making a living. But women usually married men in the same class as them.

Barbara Ehrenreich talks about how hard it was for her growing up and also some of the things went through. She talks about her job as being and house keeper and how she thought the job was going to be easy until she actually start working. She mentions how much work they had to do for only seven dollars and something. She said that the people she was working for was paying the company twenty five dollars and hour but the company what take majority of it an only pay them seven something. She felt bad because the people she was cleaning for never even bother to ask how much they where getting paid, so toward the end of the show she said for those who have house keepers should just clean their house there self. She also mentions her job at Wal-mart and how stressful she thought that was. For the simple fact, people would come in their in just trash her department and she would have to organize it. Than she talks how they would not pay you for overtime they would always try to get over on you by telling you to clock out and than ask you to do more work. Than she gave her opinion about the different drug test and also personality test that many work places require you to take. She felt like what ever she did was her business and no one else so she was against that drug rule to.

I found Barbara Ehrenreich to be a person who knows how it feels to struggle in the world but she knows that this world can be a better place when it comes to making a better living. I agree on everything she talk about for the simple fact, that my family was once a victim of welfare. I mean if more people thought like her this world would be a better place than what it is now. But she shoed us that don’t nothing come easy in this world especially money. I would recommend that everyone should go and purchase the book Nickel and Dime for the simple fact a lot of people can relate to everything she is talking about it.

Cloning involves the scientific process of producing duplicate copies of genes and organisms by nonsexual methods. It involves mitotic cell division in which a new organism eventually results as a genetically identical replica of the original DNA donor. The cloning process takes a donor body cell (with a nucleus) and nurtures it in low nutrient conditions to the point where the body cell division stops. Then, an unfertilized maternal egg cell is taken and its nucleus is removed, therefore leaving cytoplasm and organelles, but no chromosomes. Following this step, the DNA donor (diploid) cell and unfertilized egg cell are either fused together by an electric pulse that eventually initiates a mitotic division or the donor DNA is microinjected within the egg. As the cell divides, an early embryo is formed; this embryo is maintained in a culture dish for several days. During this period, the embryo develops into a hollow ball of cells and is implanted into a surrogate mother’s uterus. This process of Nuclear Transfer soon allows for the newly introduced embryonic cell to dictate the growth and maturity of the new organism without sexual reproduction ever occurring. The result, at birth, is a clone.

In examining the cloning process and its importance to modern day scientists, the idea of Xenotransplantation must be considered. Xenotransplantation is the transfer of organs and tissue from one unrelated species to another. It is another method of animal cloning that may be used to help humans in need of healthy and functioning organs. A global shortage of human organ donors has sparked a great deal of research and investigation into xenotransplantation. The process of cloning in xenotransplantation is vital because of certain immunity and organ-rejecting phenomenon that occurs within typical medical transplantations. Naturally, if a foreign organ is introduced to a body, the body’s immunity and defenses immediately attack and destroy anything that is not recognized as being original. It is because of this that animals (particularly pigs) are used in creating and harvesting organs that are less likely to be attacked by human body defenses by what is called hyperacute rejection. The cloning process is used by the injection of human DNA within pigs so that the pigs are genetically modified to reduce rejection by a human host, when it comes time to extract and inject organs.

Pigs have been especially useful in research studies because of the degree of compatibility and convenience they provide for researchers and humans in general. Pigs are generally easy to clone in fairly sterile environments. Researchers also turn to pigs because they give birth in fairly large litters �this implies a potential for abundance for any future for organs intended for the growing number of people who need transplants. Pigs also grow and reach maturity quickly and have organs that are nearly match the sizes of human organs; these too are valuable characteristics in terms of using them for medical transplants. Despite the fact that pigs appear to be very enticing for xenotransplantation initiatives, there is still the underlying fact that humans and pigs are two different species separated by genetics.

Even though the pig stands as one of the most ideal candidates for xenotransplantation procedures, the fact that it is an animal leaves open room for wide debate over several safety risks. Aside from the risks of body rejection of organs, there remains another question of whether or not animal diseases will be introduced into humans upon transplantation or shortly thereafter. For example, primates such as chimpanzees, (one of the closest in size and blood types to humans), are not selected as prime xenotransplantation organ donors, in part, because of disease implications. Though these primates share some body size and blood type similarities with us humans, the virus that causes AIDS in humans is thought to originate from chimpanzees. Another such example of possible virus transmission is that of the deadly Ebola virus. Other possible risks that are drawn into xenotransplantation are of the negative effects that might emerge if transplant patients are released back into mass populations, posing a public health threat.

This topic is shrouded in much controversy not only because of the epidemic potential it has but also because the process of xenotransplantation is still relatively new and a great amount of pigs may be killed in order to achieve the desired results suitable for organ harvesting. There are activists that take the position that just because our donor participation among humans is low, we have no right to look elsewhere (in animals) for the solutions. The argument is made on the accusation that scientific researchers would be inflicting great animal suffering, exploitation and harm. Many questions of ethics come into play in this as well. The question of whether the integrity of the human body will remain intact also poses a concern for many. But no matter what side argues for or against the process, it still remains in the research process, which still leaves time for more debate on whether or not it is a suitable method of medical practice.

In evaluating my personal ethics, this practice is not completely favored. By looking at the benefits and negative aspects of this procedure, I would say that there are more negative aspects. I also agree with animal rights activist approach. Pigs should not be exploited and killed in the name of medical science. On the other hand, it would be great to have an answer to all those waiting on a list for new organs. But if anything, organ transplants should continue to be done among humans, because there is a less of a risk of disease and viral exchange. The numbers of American organ donors is low, yet I get the impression that there have not been greater efforts to encourage organ donation. Though the prospect of xenotransplantation seems promising and is pursued with good intent, there is also much that is unknown about it. I feel that there are assumptions and ambitious measures taken too soon without the proper knowledge, expertise and certainty required to put anything into affect. Overall the process of cloning is something that may seem scientifically appealing in fiction, but not in reality. I think that just because we as humans can genetically alter and tamper with nature by cloning and genetic alteration, doesn’t mean we should.

Two hundred fifty words of bullshit. I am going to be here for a very long time. This shit is the pits. I hate the New York Yankees. The Boston Red Sox should have won the series. On another note, last night, the Chicago Cubs should have finished off the Florida Marlins. In Game Six, a stupid ass fan decided to reach into the glove of Moises Alou, and ruin what would have been a foul-out fly ball. However, after Alou decided to spaz out at the fan, the game took a turn for the worse. This has somehow turned into a drama story. In the eighth inning, the Florida Marlins somehow scored an un-precedented eight runs. This meant that the Florida Marlins now took a lead in the game, by a score of eight to three. I only wish that this had never happened. Unfortunately, the Marlins, and their young team of scrappers, went on to win game six, and take game seven. Because of this horrid turn of events, the Florida Marlins bested the Chicago Cubs in their seven game series.

Tonight, the Boston Red Sox somehow blew a major lead in a decisive game seven. Pedro Martinez was left on the mound for too long, and this resulted in him allowing five earned runs, which tied the game, heading into the ninth inning. The Boston Red Sox put up a valiant fight against the heavily favored Yankees. However, a win, and a chance at a world championship was not in the cards for the Sox. New York won the game off an Aaron Boone homerun in the bottom of the eleventh inning, to put an end to all of Bostons dreams.

The World Series will now be played between the Florida Marlins from the NLCS, and the New York Yankees of the American League.

Discuss the transition from an analogue to digital PSTN environment and give rough dates for each development.

The first electrical telecommunications were transmitted by the wire telegraph, invented by Samuel Morse in the 180s. The telegraph utilized the interruption or reversal of a direct current electrical circuit to cause a remote sounder to produce a click at the beginning and end of each interruption or reversal. A short interval between clicks was called a “dot,” and a longer interval (about three dot intervals in length) was called a “dash.”

Messages were transmitted by sending dots and dashes in conformance to the Morse code, which represented letters of the alphabet, numbers, and punctuation marks by combinations of dots and dashes. As many as six dots and dashes in combination were used to represent one character, and maximum sounder speed was around four clicks per second, resulting in a maximum transmission rate of about 0 words per minute. The messages were decoded by telegraph operators and initially recorded as handwritten copy.

The telegraph had a tremendous impact on the United States and the world. For the first time ever, reports of events from great distances were available almost instantaneously. The railroads granted right-of-way to telegraph companies and negotiated service contracts with them.

livepaperhelp.com



The railroads used the telegraph systems to control the movement of trains, and the telegraph companies provided telegraph service to the public. The newspapers used the telegraph to gather news of happenings around the country. During the Civil War military orders, information on troop movements, and reports on the outcomes of battles were transmitted by telegraph.

In 1850, Western Union was formed in Rochester, New York, to provide message service to the general public over its privately controlled but publicly accessible network. By 1851, more than 50 telegraph companies were in operation in different regions of the United States.

Western Union profited from the wartime business. Over a short period of time it absorbed the independent telegraph companies and became one of the largest corporations in the United States.

In 1850, the first undersea telegraph cable was laid between France and England, extending wire line telegraphic communication internationally. With manual operation, the transmission rate was still slow.

Printing Telegraphs and the Teletypewriter

David E. Hughes first introduced a printing telegraph in 1855. A continuously rotating wheel that had letters of the alphabet, numbers, and other characters on it. Keys at the sending end were operated to send electrical impulses that would stop the wheel and print when the desired character was over a moving strip of paper. The Hughes tele-printer increased the maximum transmission speed to between 40 and 45 words per minute.

In 1874 J. M. E. (Emile) Baudot invented a code that represents each alphabetical character, number, punctuation mark, or control command by a group of five equal-length units. Each unit could be in one of two possible states voltage present on the line representing a 1, or no voltage on the line, representing a 0. Alternatively, a 1 can be represented by a positive or negative voltage and a 0 by the opposite polarity. Systems that consist of only two digits are called binary systems, and bit is an abbreviation of the term “binary digit.”

Baudot developed prototypes of tele-printers (also called teletypewriters) during the 1870s, and by the early 100s teletypewriters that used a version of the Baudot code began replacing manual telegraphy. Start and Stop bits were added to denote the beginning and end of each character.

The teleprinters operated in the range of 100 to 600 baud, which is equivalent to 0 to 100 words per minute, a significant improvement over manual telegraphy.

The Telephone

With the invention and demonstration of the telephone by Alexander Graham Bell in 1876, the electrical transmission of sound became possible. Sound waves were converted to electrical waves by a microphone at the sending end. The electrical waves were transmitted over a pair of copper wires and reconverted to sound waves at the receiving end. The electric waves are analogous to the sound waves. Thus, this type of transmission is called analogue transmission.

The human ear can recognize sounds of frequencies between 0 and 16,000 Hz, with maximum sensitivity around ,000 Hz. The maximum hearing range will vary from person to person and response to the higher frequencies diminishes with increased age.

The human voice includes frequencies in the 00- Hz to 5,000-Hz range. Telephone company personnel determined that intelligible speech could be transmitted over circuits that pass the band of frequencies from 00 to ,000 Hz and established this range as the requirement for voice circuits.

The Bell Telephone Company was formed in 1877 to produce telephones commercially. Western Union created the American Speaking Telephone Company, a competitor to Bell, in the same year.

In 1878, the Bell Company hired Theodore N. Vail, a former superintendent in the U.S. Post Office, to manage the organization, and it filed suit against the Western Union Telegraph Company for infringement of patents. In 187, an out-of-court settlement was reached wherein Western Union agreed to give up the telephone business and Bell agreed to stay out of the telegraph business. In 1880, the American Bell Telephone Company was organized, and years later Bell purchased the Western Electric Company to ensure a ready supply of telephone equipment.

The first long distance telephone service, between Boston, Massachusetts, and Providence, Rhode Island, began on January 1, 1881. Vail, now the president of American Bell, realized that the long distance lines were the key to monopolize the telephone network and began to acquire control. In 1885, the company was incorporated as the American Telephone and Telegraph Company (AT&T) with Vail as president. Vail left AT&T in 1887.

Aim To investigate a factor that affects the rate of photosynthesis.

Outline A piece of pondweed will be cut and placed into a beaker containing water and sodium hydrogen carbonate. A lamp will be shined on to the pondweed and the amount of bubbles released from the plant will be counted. The lamp will be adjusted to different distances from the plant to try and obtain different results.

Photosynthesis Equation

6CO + 6HO light energy & chlorophyll C6H1O6 + 6O

livepaperhelp.com



Variables

Experimental Variable- Light intensity is to be the variable explored in this investigation. Increasing or decreasing the distance from the light source to the plant can vary light intensity.

Fixed Variables-

Light Wavelength (color)- Light energy is absorbed by pigments in the leaf such as chlorophyll. Chlorophyll easily absorbs blue light, in the 400-450 nm range, and also easily absorbs red light in the 650-700 nm range. Chlorophyll does not absorb green light or yellow light effectively but tends to reflect them, decreasing the amount of light absorbed and decreasing the rate of photosynthesis. Why the rate of photosynthesis increases or decreased from the amount of light energy absorbed is what is being investigated in this experiment. The light color can be fixed by using the same lamp throughout the experiment.

Carbon Dioxide- CO concentration can affect the rate of photosynthesis since the more CO in the air, the more CO that can diffuse into the leaf. This variable can be fixed by adding a fixed amount of sodium hydrogen carbonate to the beaker and plant. The experiment should also be completed in one session and under two hours so the plant does not use up a significant percentage of the CO.

Water- Water is required in the photosynthetic reaction. When plants lack water, their stomata close to prevent further water loss. At the same time, closing the stomata cells doesnt allow CO to diffuse into the leaf. Water is also therefore, linked to the carbon dioxide factor. Water can be kept a constant by keeping the same amount of water in the beaker.

Temperature- Enzymes are used in photosynthesis and the respiration of the plant. Therefore, increasing the temperature will increase enzyme reaction and the photosynthetic rate until a certain point is reached when the enzymes denature. The temperature can be kept somewhat a constant by performing the experiment in one session, when the air temperature shouldnt change enough to affect water temperature. A transparent glass block will also be placed in front of the lamp to retain some of the heat from the lamp.

Plant- Different species plants have different photosynthetic rates due to the different leaf structures of the plants. Even plants of the same species may have slightly different rates of photosynthesis since there may be more or less chlorophyll in the leaves to absorb light. The size of the plant is also important since this would affect the amount of surface area for gas exchange. The only solution to controlling this variable is by using the same plant throughout the experiment.

Limiting Factors- Light, carbon dioxide, temperature, and chlorophyll are all limiting factors, meaning that even when there is surplus of every other variable, the rate of photosynthesis will be limited by the limiting factor until there is an optimal amount of the limiting factor to increase the rate of photosynthesis further. Otherwise, the rate of photosynthesis can no longer increase.

Prediction I predict that increasing the light intensity will increase the rate of photosynthesis at a proportional rate where LI is inversely proportional to 1/d when LI= light intensity and d= distance (from light source to plant). This is true to a certain point until another factor is limiting the rate of photosynthesis.

Hypothesis When chlorophyll absorbs light energy, the light energy cannot be immediately used for energy conversion. Instead the light energy is transferred to a special protein environment where energy conversion occurs. This happens by using the energy of a photon to transfer electrons from a chlorophyll pigment to the next. When enough light energy has been harnessed at a reaction center, ATP can be synthesized from ADP. During this reaction, oxygen is produced as a by-product and it is the oxygen bubbles that are being measured in the experiment. The greater the light intensity, the more light energy that can be transferred and harnessed to fuel reaction in photosynthesis.

Light intensity is inversely proportional to the distance squared because the light energy spreads out as it travels further and further from its source. Light energy travels along the circumference of an expanding circle. When light energy is released from a point, the energy is dispersed equally along the circumference. But since the circle is expanding, the circumference increases and the same light energy is distributed along a greater surface.

Method

1. Set up the apparatus as shown in the diagram above but leaving out the pond weed, funnel, test tube, water, and the sodium hydrogen carbonate.

. Fill the beaker with 450 cm of water and 50 cm of NaHCO.

. Select 1 or pieces of pond weed each roughly 5-10 cm long and cut off the stems.

4. Place the pond weed in the beaker and secure the funnel upside down over (on top of) the pond weed using the plasticine.

5. Place a water-filled test tube upside down and over the funnel (see diagram).

6. Place the ruler so that the 0 measurement is aligned with the side of the beaker. (distance measured from side of beaker to edge of light bulb)

7.) Place the lamp directly in front of the plant so that it is 0 cm away from the beaker. 8.) With the light shining on the plant, record the number of bubbles emitted in a 1 minute duration. Switch off the lamp and wait for another minute before taking another reading.

.) Take readings at the current distance and move the lamp 5 cm further away from the plant.

10.) Repeat steps 8 and until readings from at least 5 intervals of 5 cm have been taken.

11.) Proceed to the data analysis stage.

Results

5 11,000 01 14 1.

40 850 8 8 7 7.7

45 60 6 5 4 5

50 580 17 17 18 17.

The temperature of the water stayed a constant at about .5O C throughout the experiment.

Conclusion

From the results that I have gathered I can state that an increase in light intensity certainly does increase the rate of photosynthesis. As was also expected in my prediction, the relationship between light intensity and the rate of photosynthesis was non-linear. From both graphs there is a best-fit curved line. This means that the rate of photosynthesis increases at an exponential rate.

However, my prediction that light intensity is inversely proportional to the distance squared did not fit into my results perfectly. The rule existed but there was often quite a large margin of error.

When measuring light intensity in terms of distance, the greater the distance, the slower the rate of photosynthesis. While the rate of photosynthesis was decreasing, the rate at which it was decreasing at was also decelerating. This is where the line in graph 1 shallowed.

When measuring the light intensity in terms of LUC, the greater the distance, the slower the greater the rate of photosynthesis. While the photosynthetic rate increased, the rate at which it increased was decreasing. This is where the line in graph shallows.

The shallowing of the line in graph 1 can be explained by the fact that light intensity is inversely proportional to the distance squared. This means that as distance increases the light intensity decreases at an exponential rate. If light intensity decreases exponentially, photosynthetic rates that depend on light intensity also decreases exponentially. The line in graph 1 would eventually reach 0 where photosynthesis stops as light intensity limits this rate.

The shallowing of the line in graph is due to other factors limiting the rate of photosynthesis. These other factors do not immediately limit the rate of photosynthesis but rather gradually. As light intensity increases the photosynthetic rate is being limited by certain factors such as carbon dioxide and temperature. As light intensity increases further, these factors limit the rate of photosynthesis even more until photosynthesis is completely limited and the graphed line become horizontal. This is when photosynthesis is being carried out at a constant rate.

The reason that a f 1/b did not apply was due to the apparatus used. The lamp that I used had a cover that directed the light energy somewhat. The light energy did not spread out as much as a plain light bulb with no cover. The distribution of the light energy was more concentrated, changing the gradient of the graph.

Evaluation

Overall, I would state the experiment as a success since my predictions were supported by my results. This is important in reflecting success only if my prediction was sensible and logical. Just as important is where the experiment was not a success and why. This photosynthesis investigation was probably not performed as accurately as it could have been due to some controllable and uncontrollable conditions. Some mistakes can be corrected.

While performing the experiment, the piece of pond weed did not photosynthesize at a steady rate, even when the distance from the plant to the light source was kept a constant. The second reading at 0 cm was far greater than the first reading at 0 cm. While the number of oxygen bubbles was being recorded, the rate at which the plant was photosynthesizing had increased several times. This may be due to the poor circulation of sodium hydrogen carbonate at the beginning of the experiment. Carbon dioxide may have initially limited the rate of photosynthesis. The readings at 0 cm and 5 cm were repeated many times until the rate of photosynthesis had begun to settle. From then on, there were no more similar problems during the experiment. To make sure that the there

The negative effects from this problem may be inaccurate data for some readings. These would show up on my graph. However, there seemed to be few anomalies than was expected when the experiment was being performed. Almost all readings were in correlation with each other and all of the anomalies were in the high photosynthetic rate end of the results. This was when the distance from plant to light source was 0 cm or only 5 cm.

A large factor in determining data accuracy is the amount of human error during experiments. The rate at which oxygen bubbles were being produced by my plant was so high that I found it difficult to count the amount of bubbles. I estimate a margin of error of at least bubbles for each reading taken. To improve the accuracy of the results, the readings would have to be taken several more times. The entire experiment could have been performed again, and the new results could be combined if the same plant is used. But the photosynthetic rate of the same piece of pond weed would eventually decrease over time anyway. Repetitions would, however, improve the overall reliability of the results.

There are quite a few factors that could affect the results of my experiment. Some of these are variables that were mentioned earlier and could not be controlled, or they were variables that were not initially considered.

While performing the experiment, some of the oxygen produced from photosynthesis may have dissolved into the water. Some oxygen may have even been used by micro-organisms living on the pond weed. The amount of oxygen dissolved or used by microbes is probably insignificant to my results since the degree of accuracy at which I measured was not high enough. Some oxygen is also used during the respiration of the plant. But since only bubbles were counted, the volume of bubbles was not as important. But to volume of oxygen produced is important, since it was volume in terms of bubbles that were measured. As the rate of photosynthesis decreased due to a decrease in light intensity, the size of the bubbles produced also became smaller. This change in bubble size was no accounted for when the results were analyzed. For a more accurate analysis of the collected data, volume should have been measured instead of bubble quantity since the size of bubbles can vary. Using a capillary tube in place of the test tube so that the volume of each bubble could have been measured could have done this.

During the high intensities I had experienced counting difficulties of the bubbles being produced. There are also factors affecting accuracy at low light intensities. With low light intensity, the pond weed receives some light energy from background light such as sunlight seeping through curtains or the light from the lamp of another students experiment. To eliminate most all background light, the experiment must be performed in a completely dark room. Even then, some of the light from the lamp in my experiment would reflect of the table and reach the plant though this amount of light is probably insignificant in affecting the rate of photosynthesis.

Temperature was also another factor that was controlled by the lamp being used. Even though a glass block was used in front of the lamp to prevent some heat from reaching the plant, not all the heat can be blocked. The extra heat, however, did not affect the temperature of the water, which stayed at between 0 and 00 C.

The method of the experiment could probably also be improved to obtain more reliable results. As already mentioned, the a capillary tube should be used in place of a test tube to accurately measure the volume of the oxygen produced. Due to the high rates of photosynthesis of the pond weed, readings should be taken within shorter time periods. I had originally chosen to count the number of bubbles in one minute but this produced miscounts in the readings. If during a repeated experiment, counting bubbles is still used, there is a smaller chance for human error when counting within a smaller time frame. If the capillary tube option was to be chosen, volume should be measured for a smaller time frame to reduce the overall time to complete the experiment. Also, during high rates of photosynthesis, it would still be difficult and impractical to measure the volume of oxygen produced for a long duration.

Due to the nature and convenience of the experiment, it could be easily modified to investigate another variable of photosynthesis. Since sodium hydrogen carbonate (NaHCO) is used to provide the pondweed with carbon dioxide. Performing the experiment with different volumes of NaHCO could vary the amount of CO. The plant would be kept at a constant distance from the lamp and a constant volume of water would be added to the sodium hydrogen carbonate. Another experiment using almost identical apparatus would be to vary the color of the light the plant absorbs. Using translucent color filters in front the lamps could vary this. Since light wave length has already been identified as a variable of photosynthesis, it would be interesting to actually test it. The only problem of this experiment is that there is no way to define or measure the color of light. Wave length would be a solution but this cannot be measured with available equipment. We only have a general idea of how to class colors. Because of this, the colored light experiment should not be taken as seriously as light intensity or carbon dioxide.

Almost two years ago in 001, Cecil Archibald Baugh called the Edna

Manley Art School inKingston Jamaica.

And years from now, if the story is told properly, that call will be

remembered as one of the most important that the year-old internationally-

acclaimed master potter made to the institution which he co-founded in the

150s.

For Baugh will make arrangements to handover his prized book collection

which includes the works of Bernard Howell Leach, the British ceramist with

whom he studied in 148 while on a British Council Scholarship in the

United Kingdom; Sojhi Hamada, the celebrated Japanese potter and George

Wingfield Digby.

“I can think of no other reliable place with which to leave these books,” he

told Sunday last week.

There are lots of others of course- Baugh went worldwide in his quest for

excellence - however Leach, Hamada and Digby (all deceased) stand out in

the potter’s memory, which when teased delivers a number of historic gems

worthy of celebration.

Point an enquiring finger at a photograph of Baugh standing erect in a

fabulous blue business suit - the only black among a group of equally

distinguished-looking men.

You’ll instantly be rewarded with a brilliant smile and a lot of interesting

information.

“That’s me, the only black man present at the launch of the Leach Legacy at

the Tate Gallery, St Ives,” he’ll say.

Located in SouthWest England, the Tate St Ives which manages the work of

artist Barbara Hepworth was opened in 1.It boast an impressive collection

of modern and contemporary art including works by Baugh’s idols Leach and

Hamada.

It’s a great source of pride to him - Leach is to pottery and ceramics, what

Bob Marley is to Reggae Music - and the perfect launching pad for the story

of his growth from a humble “Yabba Man” to the master artist who, among

other achievements, was commissioned to make a bowl for Queen Elizabeth

11 by the government in 15.

Born on November , 108, in Bangor Ridge, Portland to Isaac Baugh and

Emma Cobran - Baugh, he was educated at the Bangor Ridge All Age Scool

before getting seriously into the art of pottery which he began to learn at age

17 as an assistant to two women who earned their living making pots using

traditional pottery techniques.

After a while he began to make water storage jars, bowls and a variety of

other items for domestic use.

By the time he was 8, he had established his own pottery in Montego Bay.

It was the perfect background for the success he was later to enjoy as a tutor

at the Edna Manley Art school for 4 years, and the recipient of several

awards including the Norman Manley Award for Excellence in 177; the

184 Kaiser Bauxite award for the development of the Egyptian blue haze in

Jamaica and the 184 Gold Musgrave award.

He’ the maker of the largest ceramic mural at the Bank of Jamaica and his

name has been indelibly set down at the National Gallery of Jamaica which

has named one of its halls the Baugh Ceramic Gallery.

Now he’s set to enjoy even more recognition - the New York Art Gallery

wants to buy one of his pots- and several other art lovers are scrambling to

own “ a Baugh”.

The need to scramble is understandable for at (he turns in a few weeks)

Baugh himself is acknowleding that his pottery making days are almost over.

“I’ve had enough. I’ve done my three score and ten. I still put a finger in now

and then because you never really finish. You can’t just stop like that.You

have to keep your finger in it until you say ‘Amen’. But I have reached the

end, that’s why I’m passing on the books,” he said.

At least one of them won’t go to the art school though.

Angella Brown, one of his students will be the recipient of one of his

favourite books, Digby’s 15 publication, “ The Work of the Modern

Potter in England”.

“This is a very important book. Few people have it. It’s for Angella, my

student,” he said.
