Environmental Ethics Essay

Environmental ethics falls under the discipline of environmental philosophy that studies how human beings relate to their natural environment. This is a wide study that involves a variety of other disciplines such as those that study human relationships, economics, the earth’s structure and biology especially ecology. Human beings being the most superior of all the living things on earth have an ethical obligation to the environment concerning the earth, air, water, other organisms and the human population, both the present and the future generation. Environmental ethics brigs up a variety of issues concerning what, when, how and why we should consider this area of study. Aspects arising include the environment’s moral value, how sustainable are the policies on environmental protection, and how do these apply to the developing nations, and what policies should be put in place to ensure that the environment is safe guarded for the future generation, among others. Many philosophers through the years have studied this topic, but it only came to be recognized as an independent discipline in 1970, due to awareness of effects of increasing human knowledge on the environment. Growing economics and populations, new technologies and development of industries all have had various adverse effects on nature, although aimed at improving life. The works of Rachael Carson, Paul Ehrlich, Aldo Leopold, among others brought about ethical concerns about the environment. Under environmental ethics, human beings have a duty towards the environment, on protection and conservation as well as having a quality life for themselves. In this context, contentious issues arise as to why we should be concerned about the environment. Should it be for us, the living human beings, the future generation, or for the environment itself regardless of our own benefits? Different personalities offer different answers to this question; hence different views have come up on environmental ethics. The issues of environmental ethics is of growing concern to the government and other institution including United Nations which have come up with incentives to people to value and appreciate nature. Earth Day which is held annually (first held in 1970) continues to create awareness and sensitize people on the value of the environment and why it should be protected. The Moral Standing We cannot handle ethics without reference to moral philosophy, which is concerned with individual behaviors and conducts. The moral standing depends on what is considered ‘right’ or ‘good’ and ‘wrong’ or ‘bad’ by an individual or a society. For instance, different societies have different views on areas like land and animal ownership, rights of the future generation, and many more. Personal conduct with respect to environmental ethics defines how people should interact with nature, regarding its exploitation and conservation. The moral standing of the ethical issues on environment are wholly placed on human beings as they are the only living things who can reason and decide on moral issues. Many of the environmental concerns revolve around man and how these affect him, thus the responsibility of environmental ethics should be solely man’s. Responsibility to the environment implies that we are aware of this task, we are able to do it, we are at liberty to do it or not, and carrying out of the task has an effect to others existing in the environment. This means that we know the damage we can cause to the environment, the effects of this damage and the prevention or solutions to these problems. This gives us a moral significance in environmental ethics, and gives us a central role. The moral standing therefore means we have the moral obligation towards nature and the capability to carry out this responsibility. When we consider environmental ethics, then, look at issues such as: †¢ Should we care about nature for itself while it’s people who really â€Å"matter†? That is if not for human beings benefit; why else should we conserve the environment? And if depleting the natural resources is necessary for life improvement, why not exhaust it? †¢ Is the loss of biodiversity, destruction of scenic geographical features for human benefit such as in agriculture so harmful to man? Where is the need to conserve a species while it has no chance of survival in the near future due to changes in earth’s patterns? †¢ Is it right for a person to own land, it being a natural resource among others, or is it morally wrong? Is it fair that 5% of the human population use 30% of natural resources, while in other less countries the population suffers due to lack of the basic resources such as food and clean water? Do these resources exist for the benefit of a few or should they be left free for use by all? †¢ Is it possible for human beings to improve nature, seeing how man seems to have no control over nature when it comes to events such as natural calamities? †¢ Do recent developments in technology relieve us of our duty of protecting the environment? For instance, does biotechnology with potential to create new species, or bring back an extinct species, relieve us of the duty to conserve the biodiversity? Or alternative sources of fuel give us a right to deplete the natural fuel reserve? †¢ Should we let nature take its course as it always has or try and preserve it without assurance that this is of any benefit, or that this only hinders the course of nature? Is there any way that nature can take care of itself without our hand, like self renewal? The main issue surrounding environmental ethics today is the activist movements on environmental protection that focus people on the wrong issues, that is the moral standing is more emotional than factual or logical. The following are essential in discussing environmental ethics and policies. Western Religion and Culture It has been viewed by some philosophers that the Western religion has adversely affected the environment as it teaches that human beings have dominion over the earth and subdue it. Others view this as a command to take care of nature as we have been left in charge. The command given in the bible to the first man â€Å"be fruitful and fill the earth† (Genesis 1:28, Holy Bible KJV) raises the question of population control, is it ethical for the sake of the environment or is it a direct defiance of God’s command? To address this sensitive topic, religion should be understood in context. At the time of the command there was only one man on earth, so he was required to ‘fill’ it, but now the earth is already ‘filled’. Is it logical to still apply the very same principles now as they did then? The culture of a people defines how they relate to and use the environment. Many of the historic events that shape the western culture have had a huge impact on the environment. Events such as the industrial revolution, technological advances and the modern culture have affected the environment. Culture can easily adapt to changing environments, as well as cause permanent change to different environments. The environment is very wide and continuous, while the environment defines cultural practices. Therefore it is ethical to put environment before culture, and change current lifestyles towards more nature friendly practices. The future generation Most of the damage to the environment is more likely to affect the future human population. This therefore calls on the currently living humans to consider the rights of those who are not yet born. We might not know exactly what that generation will require but we are well aware of the basic needs of living beings; food shelter and basic health. Based on these we can have a model of what the environment should offer the future human beings. Therefore it is our moral obligation to them to utilize nature as much as we need to but ensure that we do not deny them the enjoyment of the same. Animals Other animals should be considered when addressing environmental ethics, since they are sentient beings, that is are capable of feeling. Although animals come after humans, they have rights and should be considered according to what they are interested in, such as feeding, living in their natural habitat, and allowed their existence. Controversy about animal rights arises in what animals exactly should we grant rights to. For instance, are insects or other smaller animals in this category? Is it right to use animals for laboratory research for medical and other studies to better our lives? The simple answer to this question is that unless it is extremely necessary, animals should not be put at risk or in adverse conditions. The harm to animals should be justified and be limited to a certain allowable level. Ecofeminism Women are seen to be closer and more in touch with nature; this is claimed by feminists concerned with the environment (Cochrane, 2007). This is because of their ability to give life, and the fact that the earth is considered female (Shiva, 1993). Thus this gives them a better understanding of nature and how to coexist in harmony. Val Plumwood, an ecofeminist believe, that feminism should go hand in hand with environmentalism as both women and the environment are under the same oppression. Another feminist argues that the problem is in trying to justify this kind of oppression thus allowing such subordination. When considering environmental ethics and policies, the domination over women and nature is a critical issue that requires attention. Economics and Ecology Economics and ecology usually appear as counter forces. Economy involves trying to allocate the limited resources while ecology looks out to protect these resources. The ever-growing human population has placed great pressure on nature and thus their distribution is highly competitive. Market forces have added more pressure to natural resources and their exploitation. Rapid growth of industries has contributed to environmental deterioration. The cost-benefit considers questions like; if nuclear power makes electricity cheaper, should this field be ventured? What is the cost of preserving a forest compared to the cost of exporting timber? These raise challenges when setting up policies on the environment because of the question of cost versus the benefit of environmental ethics. Technology Technology has had a huge impact on human life as well as on the environment. The effects of technology are both beneficial and adverse. The medical, agricultural, communication and energy industries rely heavily on technology to better human life. Technology has the power to destroy nature as well as replenish it. The technological advances that are most potentially harmful include nuclear technology that is able to annihilate nature and biotechnology, which has the potential to alter the natural species boundaries. Since all technologies come with potential risks along with their benefits, ethical consideration must be made with regards to the environment. Conclusion In studying environmental ethics, the first thing is to ask the question ‘what should be done about the current environmental situation and how should it be done? ’ The other consideration is the importance of individual natural resources and how much effort and cost we should dedicate to protecting such. This should be based on facts and not feelings, like and dislikes. It is important that policies be based on an integrated system that has in mind all the components of nature, as well as involvement of the government, institutions and other countries. The following should be noted when considering environmental ethics: †¢ The environment is not a resource just for us but for those we share it with (animals, plants and microorganisms) and for the future inhabitants of the planet. †¢ Nature is continuous with continuous flow of energy, but with rapid exhaustion, the environment is not able to renew itself. †¢ Some of the artificially made substances are capable of spreading all over the earth out of our control and nature has no way getting rid of them, for example nuclear waste, fluorocarbons, DDT, GMOs, etc. †¢ Our policies on environment affect the whole world since everything in nature spreads. We should be sensitive to the needs of other countries especially the less developed when considering environmental ethics It has to be demonstrated clearly that the policies we put in place concerning the environment have defined benefits for all concerned otherwise the area of environmental ethics will always be viewed with sharp critism. The benefits of conserving the environment should be clearly elucidated and put out for all interested stakeholders.

Summary Sorry, But Your Soul Just Died - 1159 Words

Ricky Vong 10/18/15 PSY 3711 Sorry, But Your Soul Just Died The article, â€Å"Sorry, but Your Soul Just Died† was an enjoyable read. Tom Wolfe article was quite amusing, and filled with details. Yet, Wolfe was able to connect and draw out the soul, moral code, and justice within the â€Å"neuroscience† discipline. It encapsulated the aggressive materialism of some new-age scientists. Furthermore, to these self-assured scientific investigators—the concept that the spirit may occur separately from the body is just absurd. Alternatively, everything is on the â€Å"threshold of a unified theory,† and a human’s â€Å"temperament,† â€Å"role preferences,† â€Å"emotional responses,† â€Å"levels of aggression,† and â€Å"moral choices† are genetically determined. And some established theories about â€Å"the mind,† â€Å"the self,† â€Å"the soul,† and â€Å"free will† are nothing but an illusion. In other words, humans’ beings are â€Å"wire d† this way, and religion was probably a mishap. The article was difficult to follow at times, however, I think Wolfe anticipated the â€Å"neuroscience revolution† would start a public debate of whether god actually existed (I guess Wolfe understood these central claims carried in thinking like this). The idea that our genetic code controls most aspects of our lives is arguable. Nowadays, scientists (cell biologists, neuroscientists, etc.) are uncovering concrete evidence that are genetic code is only one of the many complex system of the human body that sways our lives.

Eozostrodon Facts and Figures

Name: Eozostrodon (Greek for early girdle tooth); pronounced EE-oh-ZO-struh-don Habitat: Woodlands of Western Europe Historical Period: Late Triassic-Early Jurassic (210-190 million years ago) Size and Weight: About five inches long and a few ounces Diet: Insects Distinguishing Characteristics: Long and sleek body with short legs About Eozostrodon If Eozostrodon was a true Mesozoic mammal--and thats still a matter of some debate--then it was one of the earliest to have evolved from the therapsids (mammal-like reptiles) of the earlier Triassic period. This tiny beast was distinguished by its complex, three-cusped molars, its relatively large eyes (which indicate that it may have hunted at night) and its weasel-like body; like all early mammals, it probably lived high up in trees, so as not to get squashed by the larger dinosaurs of its European habitat. Its still unclear whether Eozostrodon laid eggs and suckled its young when they hatched, like a modern platypus, or gave birth to live babies.

The Social Responsibility Of The Workplace - 2398 Words

Introduction Archie Carroll defines corporate social responsibility (CSR) as â€Å"the social responsibility of business encompassing the economic, legal, ethical, and discretionary expectations that society has of these organizations at a given point in time.† (Crane, 5) Interesting enough, there has been an abrupt growth of firm’s engagement in CSR within all industries. This is the result of growing requests from the civil society demanding firms, of all sizes, to legitimize their practices. (Crane, 4) More importantly, workplace issues have become an integral part of corporate social responsibility. This includes a firm’s lacking efforts in its occupational health and safety, and its fair pay and conditions, amongst others. (Crane, 253) As employees reside in the midst of companies engaging in corporate social responsibility, the reputation of the firm relies profoundly on ensuring all those within the in-house workplaces as well as the outsourced workplaces are treated justly and within the operating country’s legislation. (Crane, 253) Further to this, social injustice that occurs can negatively affect the firm’s reputation and brand favorability. (Crane, 254) Therefore, it was within the firm’s best interests to fulfill their core corporate responsibilities in the workplace.

Offset Printing History Free Essays

string(88) " The Chinese writing system was a pictographic and ideographic method of communication\." 1 History of Printing Presses Printing is a method of transferring an image to surfaces for the purpose of communication. A printing press is a mechanical apparatus for applying pressure to an inked surface resting upon a print medium. The invention of the printing press is considered as the most influential event in the second millennium revolutionizing the way people learn and communicate. We will write a custom essay sample on Offset Printing History or any similar topic only for you Order Now Rubbings from stone inscriptions were an early reproduction method in which images were carved into stone, similar to the gravure process. The substrate, which was a thin strong paper, was moistened to make it soft . A kind of adhesive is placed on the surface of the stone. The paper is placed over the surface of the stone and a stiff brush is used to rub the paper over the stone and into every depression of the stone. Ink is applied over the paper after it was dried. The paper is peeled off from the stone and a reversed image within black ink was revealed. Stone rubbings were used to print books, especially religious texts and historic classics. Drawing materials include charcoal, inksticks, graphite and wax. Seal Printing and the Origin of Letterpress Printing The Chinese also used a method of reproducing images that is similar to our present-day rubber stamp method (Fig. 1:1) called seal printing. Before seal printing was invented, the Chinese used a receipt-like system to transact business. Two ends of a bamboo stick were written in duplicate for a particular business transaction. When the transaction was completed, the bamboo stick was broken and each member would receive a record of the transaction. For nobility, the emperor provided a token of jade. The jade was broken and one half was given to the subject and the other half kept by the emperor. A seal stamp made of clay eventually replaced the tokens. One method of seal stamping was to force an impression into a surface with the seals. The other method was to ink the seal and transfer the wet inked image to a substrate. Presswork and Bindery Processes 1 An early form of seal printing was the use of signet stones. These stones were used in Babylon and other ancient countries as an alternative for signatures and as religious symbols. These stones or devices consisted of seals and stamps for making images on clay. The stone, often located on a ring, was dabbed with pigment or mud and then pressed against a smooth surface to make an impression. Fig. 1:1. Chinese seal and print. Fig. 1:2. Chinese ink stick. Block Printing in China The Chinese developed a method of printing in the fifth century in which a wooden block was used to reproduce images on certain surfaces over and over again. Wooden blocks were made from coniferous wood, honey locust trees, jujube trees, boxwood, and date and pear trees. Each tree had advantages and disadvantages as far as printing was concerned. The coniferous wood trees had a problem of uneven printing because of resin that was impregnated in the wood. If delicate and fine line images in illustrations were required, the honey locust tree was used. For text, the soft boxwood was used, while the pear tree provided the best wood to use for various types of images, followed closely by jujube and date trees. Blocks were soaked in water for about a month after they were cut. If the blocks were needed in a hurry, they were boiled, left to dry, and then planed on both sides. Some printers used both sides of the blocks. The printer had to cut away all portions of the block except the image area (Fig. 1:3). All images had to be carved backwards so that when printed on a substrate, the images would appear correctly for reading. The wood carver had to be very skillful in carving text and illustrations backward. These blocks marked the invention of letterpress printing. The non-image areas of the block are below the surface of the form, and the image areas are on the surface of the form. The printing method was simple. Ink was rubbed on the surface of the form with a brush (Fig. 1:3). A sheet of paper was then placed over the form with gentle pressure so it could receive the images . A dry brush was used to press the sheet against the form. It must be noted that the original paper was so thin that usually only one side was printed. Because the paper was very translucent, blank sides of the printed sheets were placed back to back in publications. 2 Presswork and Bindery Processes Fig. 1:3. Chinese wooden block printing. Fig. 1:4. The Diampond Sutra. A color technique was developed during this time. Color separated blocks were carved and printed in register with other color-separated blocks and text as well. This was the first attempt at multicolor printing. An important invention in printing technology occurred during the Song Dynasty. It was the invention of movable-type printing. A commoner by the name of Pi Sheng used movable-type blocks for printing during the Qingli years (1041-1048) of the Northern Song. This invention ushered in an era of movable-type printing and is a significant milestone in the history of printing. This invention soon died in China because it was very complex. The invention soon found its way to Europe in the fifteenth century. Movable Type An alternate method of reproduction called movable type was developed in the eleventh century in China. This method was established well after the wooden block method, which came around the fifth century. Movable type consists of individual letters, characters, and symbols creating a language or an alphabet (Fig. 1:5). These elements could be used in the printing of one form, and then be taken apart and used to print other forms. The thousands of different characters in the Chinese language made the use of movable type cumbersome and slow. The Chinese writing system was a pictographic and ideographic method of communication. You read "Offset Printing History" in category "Papers" The Chinese alphabet system consisted of almost forty-thousand characters. Each character represented something in real life such as trees, animals, and pottery. Pi Sheng is given credit for the invention of movable type. He used clay and carved individual characters. The carved letters were put into fire to harden them. A metal frame with a mixture of wax was used as a base for evening out the surface of the type. The typefaces were set close to each other to make up a form of type. The entire block of type was then forced into the waxed metal tray and planed down with a smooth board after the wax was melted down in an open flame. Presswork and Bindery Processes 3 Pi Sheng reasoned that each type or character was to be used over and over again. One advantage of the movable type method is that characters could be deleted or inserted without throwing the entire form away. Fig. 1:5. Chinese movable type. Fig. 1:6. Movable type printed document. The Middle Ages in Europe Before 1450, the majority of books in Europe were produced by the arduous task of manuscript writing and recopying. The few exceptions were books that were printed by the wooden-block method, which was introduced into Europe by the year 1400. This slow, laborious process required skillful workers. Block printing was also used for illustrations in books (Fig. 1:3) and in the printing of playing cards. During this era, a period that saw little or no advancement in the arts or sciences became known as the Dark ages. This period was also marked by a lack of communication. Monks, who worked in monastery rooms called scriptoriums or writeries, produced the majority of books written during the Dark Ages. The religious scribes were responsible for the recording of history and the production of books, as well as most other intellectual activity during this period. The bookmaking trade was highly specialized. Books were elaborately decorated with colored initials, and they often displayed special gems, precious stones, and gold on their covers. Books were scarce and the average person could not afford them. In addition, most people could not read or write in Europe during this era. During the Dark Ages, books were highly illustrated, since this facilitated communication. Many illustrations were featured in religious books as well as on playing cards. These illustrations were engraved in wood or metal, inked, and impressed on the sheet, a process that required great skill. There is proof 4 Presswork and Bindery Processes hat blocks were exchanged between printers. Several illustrations appeared in different publications. The same images were often used to illustrate different subjects. Type and illustrations at first were printed in two separate impressions because they were produced at different heights. Over time, type and illustrations were produced at the same height. The Renaissance e ra, a period that was marked by an intellectual awakening, began around the thirteenth century. People began to study the sciences and the arts and to explore their environment. Many discoveries were being made, and people wanted to have knowledge of new ideas. Fig. 1:7. Statue of Gutenberg. Fig. 1:8. Gutenberg style screw press. Fig. 1:9. The Gutenberg Bible. The Gutenberg Era (1397-1468) During the Renaissance, people experimented with methods for the faster reproduction of books. One result of these experiments was the successful use of movable cast type and a press in printing by Johannes Gutenberg (Fig. 1:7). The invention was revolutionary for several reasons. European languages, in contrast to those of Asia, were alphabetic. They consisted of relatively few characters, such as the twenty-six letters of English. This small number of different characters made the use of individualcharacter types (movable type) practical. Casting each character in quantity from a mold and using a press for printing permitted very fast reproduction of written materials. Through experiments and innovations, Gutenberg perfected the printing process before the famous printing of the bible. Each page printed had thirtysix lines per page. Later the lines per page increased to forty-two. Because of this invention, printing soon spread rapidly throughout Europe. Books became plentiful because they could be printed more quickly. Many persons could now afford books, and printing fulfilled the demand. Intellectual activity and learning began anew. Because of the impact of books on the culture of Europe at this time, printing became recognized as the art that preserves all the arts. The following reasons help to further explain the importance of the invention of movable type: 1. With movable type, a greater degree of accuracy was possible. 2. The supply of books increased greatly. Over twenty thousand volumes for one book could be produced in one year. Presswork and Bindery Processes 5 3. Because books were plentiful, they were affordable. They became readily accessible among all classes of people. 4. The invention of printing stimulated the desire for learning. The invention of printing, more than any other invention, was credited with bringing Europe out of the Dark Ages. 5. A standard alphabet was in place. Despite many languages on the European continent, thousands could share from the same invention. Presses were set up in Holland, France, England, and other European nations. 6. Gutenberg invented a press (Fig. 1:8) fashioned from a wine press. Ink pads, which were made of leather stuffed with wool or horsehair, were used to apply ink to the form. . The ink that Gutenberg used was have been made from linseed oils and lampblack. Later it was discovered that traces of lead, titanium, and copper were also used. Gutenberg could not use the India ink produced in China, because it did not print well from metal types. 8. Gutenberg’s own contribution was a punch and mold system for producing metal types. This metho d created the mass distribution of movable types for printing. Despite the accomplishments of Gutenberg and other European printers, we cannot forget the Chinese influences on their inventions. These inventions eventually made their way to Europe via explorers, who came back with startling discoveries, including paper, playing cards, movable type, block printing, image prints, and paper money. The printing trade was not profitable. Gutenberg himself did not become rich from his innovations and contribution to the world. The problem lay in the marketing of books in Europe during that time. Although the demand for books and other printed matter was great, methods to market and transport books needed to be developed.

The key to the invention of printing lies in the manufacturing of movable type. This technology had to be perfected in order for the printing process to be developed. A few inventors worked on the development of movable type. A punch of a particular type style and size had to be produced. This punch was used in making an impression of the typeface in a mold. The mold was made from copper, which is soft enough to receive the impression from a steel punch, but durable enough to withstand the heat from the molten metal that was poured into it to produce the type. The punch itself had a reversed character, which was reversed into the matrix as a positive recessed character. A wrong reading character was produced from the casting of molten metal in the mold. The person that produced the punch was often the designer of the typeface. Fig. 1:10. Fifteenth century typesetting and type casting (Cary Collection). The term unjustified matrix or strike was referred to as matrix that was produced by depressing the punch within the copper. The term matrix is used after the copper with its impression is fitted within the mold for casting (Fig. 1:10). The goal in the casting of type was to produce type of equal height. This was necessary in order for printers to obtain an even impression with few difficulties. The matrix and its fitting within the mold were the key factor in the controlling of the type height. This was accomplished by using the same mold throughout the manufacturing of a font. In addition to the type height, the paralleling or the side-by-side placement of the type was also important. If type were not produced on a square body, then it would not stand straight and would slant when locked together with other characters. Presswork and Bindery Processes 7 Molds were made up of two parts and screwed together in a parallel adjustment. In this way the mold could accommodate matrix of varying size. During the hand casting process, a worker could face shrinking of type, uneven filling of the molten metal in the mold, and injury from the heat of the molten metal. The process was slow, but the type could be used for thousands of jobs. By the mid-nineteenth century, automatic methods replaced the manual methods of typecasting. Workflow in the Fifteenth Century The workflow in the fifteenth century included composition, imposition, printing, and binding. In the composition stage, once the text was decided on to print, then the volume of copy was determined. Lines per page as well as the total number of pages for the job were determined. The printer would then know how much paper was needed for the job. The compositor set the type for the job using a composing stick. Every time the stick was filled, the lines were transferred to a metal tray called a galley. Pages were formed in the galley. Pages in the fifteenth century were arranged on large stones in printer spreads. Pages were enclosed by wooden pieces, which are called furniture. A metal frame called a chase surrounds all pages and furniture. To secure the form, locks or quoins were used. One page with no printing on the other side was called a broadside. Two pages were called a folio; four pages, a quarto; and eight pages, an octavo. A pressman pulled a proof sheet from the imposed form (Fig. 1:11). The proof was given over to a corrector and a reader. The reader read the original copy as the corrector trailed along on the proof sheet to ensure that the text was the same. This process continued until all corrections were found and changed. Because of these continuous changes, no single copy of an early printed book is identical to any other. Fig. 1:11. Fifteenth century printing (Cary Collection). Paper was prepared the day before the actual press run. Piles of sheets each were set out, wetted, and allowed to stand overnight. This was necessary because the common screw presses of the time did not have enough power in them to force dry paper to evenly take the ink. 8 Presswork and Bindery Processes Two pressmen were involved in the printing process. One applied ink to the type, and the other pulled the bar and worked the paper. Pulling the bar required a lot of energy and printers would take turns in this process. Ink balls were used to applied ink to the form. These ink balls were made of leather pads, mounted in wooden cups and handles, and stuffed with wool or horsehair; they were then covered with a sheepskin pelt. Ink balls were inked, and ink was placed over the form in a rocking motion. A sheet of paper was then laid on the tympan. The tympan, paper, and frisket were folded together onto the form. The pressman then pulled the bar toward himself. This caused the turning of the screw, drawing the platen down and forcing the paper against the inked form. It sometimes took two pulls to print one form. The carriage was cranked out from under the platen. The tympan and frisket were raised, and the paper was removed. Sheets of paper were printed on the reverse side immediately while the sheet was still damp. Printing on both sides of the sheet is called perfecting. After the job was printed, the compositor cleaned the ink off the forms, unlocked the type, and distributed the type into the cases. Printed sheets were sent to a drying room and hung up in sets to dry. They were then piled into heaps on a long table and collated by signatures. Next they were folded once, pressed, and baled for delivery or storage. Fig. 1:12. Adams power platen press. Fig. 1:12a Early inking apparatus. Evolution of inking rollers. Fig. 1:13. Ink balls. Fig. 1:14. Ink brayer. Fig. 1:15. Inking rollers. Presswork and Bindery Processes 9 The Power Platen Press In 1830, Isaac Adams of Boston invented a press, which combined the advantages of the hand press and a press that could print larger forms. The platen on this press was stationary with the bed of the press rising to make contact with the platen to print. The form would be inked when the bed of the press returned to its lowest position. At this point the inking rollers would transfer ink over the printing form. A frisket was used to carry the sheet to the printing position (Fig. 1:12). The average speed of these presses was around 800 sheets per hour. Inking rollers evolved from a hand frame with two handles automatically inking rollers, to the use of vibrating rollers to drive the rollers in the unit. An earlier method of inking employed a â€Å"roller boy† or an â€Å"assistant pressman†. Soon the inking apparatus (See Fig. :12a) was run by power, which was signaled by the action of the bed moving up and down. The Job Presses Job work consist of smaller work such as tickets, circulars, business cards and bills. This type of work became problematic for hand-press printing where the demand was in place for smaller, faster and more accessible presses. One of the first job presses was called the Adams press. This press did not meet the qualifications that were needed to run smaller job work. S. P. Ruggles of Boston introduced a series of presses in 1830. They were known as â€Å"card presses†. The card press was manufactured with a flat side on the side of a cylinder supported between side frames. A second flat surface known as the â€Å"platen† was directly across from the bed of the press. Rollers on the press, which traveled around the cylinder, did the inking. The largest press sheet on the press could accommodate a press sheet of 6† X 9†. Other notable presses include: The Albion Press of 1835 (Fig. 1:19), The Paragon Press of 1829 (Fig. 1:17), the Stanhope Press of 1816 (Fig. 1:20) and the Chandler and Price Platen Press of the early 1900s (Fig. 1:18). Harrison T. Chandler and William H. Price founded Chandler and Price Company in 1881 in Cleveland, Ohio. Chandler and Price manufactured machinery for printers including hand-fed platen jobbing presses, paper cutters, book presses, and assorted equipment. Fig. 1:16. Clymer-Columbian Press. Fig. 1:17. Paragon Press. 10 Presswork and Bindery Processes Fig. 1:18. Chandeler Price Press. Fig. 1:19. Albion Press. Fig. 1:20. Stanhope Press. Many job presses came out with several improvements over the years. These improvements included: †¢ Larger press sheet sizes. †¢ Faster press speeds. †¢ Better synchronization of the bed and the platen. Improvement in the inking roller application. †¢ Better impression devices. †¢ Automatic feeding and delivery. The newspapers were printed on wooden hand presses operated by levers and screws. It was not until around 1816 that the new iron Columbian press came into general use. The Columbian press (Fig. 1:16), invented by George Clymer of Philadelphia, had, instead of a screw, a series of compound levers that multiplied the pull of the operator. All hand presses were slow. The forms had to be laid by hand and the inking of the form was notably poor and of uneven quality. Web Offset Development With the nineteenth century came the addition of the steam-powered press, the cylinder press and the web press. An American inventor by the name of William A. Bullock (Fig. 1:32), patented the web press. The web press printed from rolls of paper rather than from individual sheets. This was followed by another American invention, the continuous roll press, devised by Richard M. Hoe. This device sped up the production of newspapers to around 18,000 newspapers an hour. In 1871 Hoe (Fig. 1:30) and company turned their attention to constructing a press that would feed a continuous roll of paper and print on both sides of the fed paper. They petitioned ink manufacturers for the development of fast drying inks. Paper manufacturers were asked to produce rolls of paper with Presswork and Bindery Processes 11 Fig. 1:21. William Bullock Web Press. Fig. 1:22. Web Perfecting Newspaper Press. Fig. 1:23. Turn bars Assembly on a Web Press. 12 Presswork and Bindery Processes Fig. 1:24. Web Press Infeed Section. uniform strength. But there were other problems that needed to be solved including the severing of sheets after printing and an accurate delivery of papers. Stephen D. Tucker, who was an employee of Hoe and Company, patented the gathering and delivery mechanism. This mechanism produced flat rapid delivery of printed sections. The web presses operated at speeds as fast as 18,000 impressions per hour. This finishing device was necessary for the production of â€Å"fold ready† products for immediate delivery by carrier or mail. The finishing steps were done â€Å"inline† or on the same piece of equipment. Initially equipment similar to the traditional folding machine was used. Conveyor belts would carry the sheet to right angle folding units, which were made up of folding rollers until the desired folded format was completed. Then in 1875 Stephen D. Tucker patented a rotating folding cylinder. This device folded the papers as fast as they were printed approaching speeds of 15,000 per hour. Paper enters from two rolls into two portions of the press. The web is printed (perfected) on both sides of the sheet and traveled towards the rotating folded cylinder. The sheets entered a triangular former, which folds the sheets at a predetermined place on center of the sheets. The sheets were then taken over a second cylinder, which gave it another fold. A knife then severed the sheet separating it from the web. The folded section traveled down a conveyor belt to be manually removed, wrapped and shipped Cylinder Press Invention William Nicholson received a patent for an idea for press in 1790 in which a form is to be placed on a cylinder over a flat bed. The substrate is fed between the bed and the impression cylinder to receive an image. The application of ink was done with rollers on this press. The rollers was composed of cloth covered with leather. Nicholson’s envision for this press was far ahead of his time. Nicholson did not have a method for producing curved letterpress plates to fit around a cylinder. The securing of the plate for printing was another mystery at that time that would have to be figured out. In 1814, Frederick Koenig invented the first automatic press (Fig. 1:25). Frederick Koenig was a clock maker by trade. Koenig’s first press was actually patented in 1810. The entire bed moved laterally, and the form received ink from a set of inking rollers placed at one end of the press. The key to the automation of this press was the metal gripper finger, which in essence replaced human fingers for providing sheets to the press. Before this time, presses had been fed by hand. The automatic press was powered by steam and was used in printing the Times of London. It printed approximately 800 sheets per hour, an amazing feat in the 19th century and adequate for the population of that time. Thomas Bensley, a printer and Andrew Bauer a mechanic, assisted Koenig. They invented a press with a bed that moved laterally with the form and an impression cylinder that pressed the wet inked image on the substrate. The impression nip, or the area that prints at any given time, is very small on a cylinder press, resulting in a much better image transferred to the substrate. More importantly, this invention prevented many injuries and damage to the press because operators were not in close contact with the moving parts on the press.

Battery of cylinder presses. 14 Presswork and Bindery Processes Fig. 1:28 Advertisement of a cylinder press. Richard Hoe and the Rotary Press Richard Hoe (Fig. 1-30) was born in New York City. He went to work for his father, who manufactured printing presses. His father experimented with cylinder presses until his retirement in 1830. Richard carried on this work after his father retired in 1830. He invented the single cylinder press, which was capable of printing 200 copies per hour. Hoe also introduced the double cylinder press in 1844, known today as the rotary press. One cylinder carried the type to be printed while the other cylinder carried the paper and provided printing pressure so that the image could be transferred to the substrate. Rotary presses requires curve metal letterpress plates. The difficulty of making these curved plates slowed the acceptance and growth of rotary presses. Curved stereotype plates were accepted and used by 1870. The rotary press became the press of choice for newspaper reproduction, business forms, catalogues and magazines. A flying splicer was introduced for the continuous printing of publications without the need of stopping the press. This device changed the rolls by attaching a new roll to and expired roll. Hoe also invented an additional press in 1847 (Fig. 1-30), which featured a type form and four cylinders for carrying the sheets through the press. It is interesting to note that a boy, who fed sheets to the cylinder, also attended each cylinder. This press produces prints at the rate of 8,000 sheets per hour. Hoe is also credited with the invention of a web perfecting press. This press feeds from rolls of paper and is printed on both sides of the sheet. The presses were powered for the most part by steam. Electric power took over in the nineteenth century as the main power source for presses. Presswork and Bindery Processes 15 Fig. 1:30 Richard Hoe (left) and his six rotary press (above). Fig. 1:31.

Evolution of polar bear lamarck and darwins theroy free essay sample

Polar bears have lived in the arctic for many years. Their bodies have adapted and developed in order for their survival in the polar region. Polar bears are able to live in the deep freeze for many reasons. They have thick fur that keeps in their body heat. They have small ears and a small tail which means they lose less heat. Their paws are so big that they act like snowshoes, and the pads on their feet have an anti-slip skin, which would be similar to sandpaper. For thousands of years polar bears have lived a great life in the North. The Inuit (a tribe) people have lived with them, hunting them occasionally for food or clothing. There was never any fear that the Inuit would over hunt the polar bears because it was dangerous and the weapons available to them were creative. In more recent times, the polar bears have been sought out by hunters, just not the Inuit who live in the North. They have been over hunted by people looking for the big trophy. Eventually in the 1970s the over hunting was brought under control by the International Agreement on the conservation of polar bears and their habitat. Polar bear number once again began to grow because of this. Though there are many theories surrounding evolution, the two stand outstanding assumptions applying to the change from Brown Bear to Polar Bear are Lamarck’s theory of Use and Disuse, and Darwin’s theory of Natural Selection. The intention of this paper is to compare this theory and decide the most appropriate in relation this event. Charles Darwin simply brought something new to the old philosophy a plausible mechanism called natural selection. Natural selection acts to preserve and accumulate minor advantageous genetic mutations. Suppose a member of a species developed a functional advantage (it grew wings and learned to fly). Its offspring would inherit that advantage and pass it on to their offspring. The inferior (disadvantaged) members of the same species would gradually die out, leaving only the superior (advantaged) members of the species. Natural selection is the preservation of a functional advantage that enables a species to compete better in the wild. Natural selection is the naturalistic equivalent to domestic breeding. Over the centuries, human breeders have produced dramatic changes in domestic animal populations by selecting individuals to breed. Breeders eliminate undesirable traits gradually over time. Similarly, natural selection eliminates inferior species gradually over time. According to Lamarck’s theory, features can be strengthened or cleared of completely through use or disuse over generations. For example, Jean Baptise Lamarck believed that the giraffes long neck was an acquired characteristic. After a lifetime of straining to reach up to eat leaves, a giraffe’s neck would elongate. Baptise thought that the offspring of these giraffes would then be born with longer necks. Lamarck’s theory has widely been disproved, especially with the discovery of heredity genetics. If the theory were correct, a man who works hard to get large muscles, would father naturally strong children. Though the physical side of the idea may be dismissed, many researchers are studying whether behavioural traits can be passed down from a parent to their young. It is thought that the polar bear evolved from the brown bear. It was likely that 100,000 to 250,000 years ago brown bears (Ursus arctos) became parted by glaciers. Most of the bears probably died on the ice. However some didn’t die because they survived due to the fact that organisms vary (Gould, 1977). This means that every litter of grizzlies has different kinds of coat thickness to keep them warm and coat colour so that they would suit their environment better, which gives them a small benefit to survive compared to some cubs of each litter. Successful individuals in each litter of grizzles repeated this simple process over and over again. This gave a rapid series of evolutionary changes (driven, most likely, by the small population, and intense selection pressure) in order to survive. Note that these new variants were not necessarily better in any exact way, or on any complete bear scale of perfection. They were simply more in keeping with their new environment than their immediate ancestors or their more unfortunate siblings. Today, polar bears are adapted to their harsh northern environment. Hecht (in Chaline, 1983) describes polar bear evolution: the first polar bear, Ursus maritimus tyrannus, was essentially a brown bear subspecies, with brown bear dimensions and brown bear teeth. So if you look at the evolution of the brown bear into a polar specifically skin and fur colour, skull and ears shapes and digestions of seal fat and the theories of Darwin and Lamarck. Darwin using â€Å"natural selection† changing what the polar bear needs to change to let them adopt and survive and Lamarck using the theory of â€Å"use and disuse if you don’t use it you’ll lose it basically. Then look at all the references and evidence and would have to say that Darwin’s theory was the one that made the most sense because you could actually see the polar bear evolving from the brown bear. The polar bear skin became thicker and keeps them warm. Also the polar bears fur colour changed to white so they suited their environments. Another change was the polar bear skull and ear this changed so they could maintain their body temperature. So I am stating that based on evidence that Darwin’s theory will win the scientific debate about the process of evolution of the polar bears from brown bears Chaline, J. 1983.
