Neutron Stars versus White Dwarfs an Example by
Neutron Stars versus White Dwarfs Neutron stars are extremely dense: they are only 10 kilometers or so in size, but have the mass of an average star (usually about 1.5 times more massive than our Sun). A single [neutron star] can hold the mass of up to 5 suns in a sphere about 12 kilometers across (Krieger 2006). Neutron stars were supergiant stars whose exploded ultradense cores becom[e] neutron stars the size of a small town (Kaler, Jim. Ask Astro. Astronomy, 32, Issue 1. 2004). (This phenomena can also create a black hole.) Need essay sample on "Neutron Stars versus White Dwarfs" topic? We will write a custom essay sample specifically for you Proceed Neutron stars are made of neutrons. Their superdense status is responsible for some of the most exotic phenomenon in the universe, such as pulsars. In 2006, astronomers discovered a densely packed sphere of neutrons spinning so fast that its equator may whirl at 15% the speed of light. The object breaks a 23-year-old record for fastest stellar spin by a sizeable margin (Irion 2006.) Neutron stars have consumed all of their own fuel and so tap into other sources for energy. Thanks to this efficient release of gravitational energy, the temperature at the center of a newborn neutron star can reach 500 billion kelvins Its likely that neutron stars are born magnetized A newborn neutron star is incredibly hot -- it is, after all, the surviving core of a star that has just collapsed and exploded as a supernova. Gravitational energy released during the star's collapse represents almost 10 percent of its rest-mass energy... Rotation offers another energy source for neutron stars. They spin rapidly at birth because the collapsing pre-supernova star "spins up"-- much as a spinning ice skater does when she pulls in her armsSome neutron stars do produce energy by thermonuclear fusion on their surfaces. (Sigg 2005). Both white dwarfs and neutron stars are the remnants of stars about the size of our sun. Neither are sustained via nuclear reactions at the core. The matter in both objects is compressed to extreme densities, and therefore both are useful for studying matter at high energies. White dwarfs are dim; neutron stars are invisible, but they all have masses similar to the sun. Like a neutron star, a white dwarf has no energy source other than what is left over from its birth. White dwarfs are dead stars, and, like neutron stars, are incapable of nuclear reactions. Also like neutron stars, they are incredibly dense. Neutron stars and massive white dwarfs can sometimes, as a result of a close encounter, create an x-ray-emitting binary pair (Morledge, 2002). Both neutron stars and white dwarfs are useful for studying matter at high densities. A typical white dwarf is a little larger than Earth but has 60 percent the mass of the Sun. It forms after a star that is born with less than eight times the Sun's mass expands into a red giant. The red giant eventually casts off its atmosphere, exposing the hot, dense core -- the white dwarf. A white dwarf does not burn nuclear fuel, as the Sun and other stars do; instead, it shines because it is hot. Since white dwarfs no longer generate energy, their evolution resembles the fading fortunes these stars have faced during the 20th century: They start off hot and bright but soon cool and fade (Croswell, 1996.) White dwarfs theoretically turn to black dwarfs, but no such star exists; it takes so long for the process to occur, that all white dwarfs are still evolving. References Ken Croswell, Ken. (1996).

The Jacksonian Revolution by Robert V. Remini essays
The Jacksonian Revolution by Robert V. Remini essays A New Generation of Political Leaders The age of Jackson initiated a shocking overthrow of the noble republican standards of the founders by the common people. It was the people's turn to be heard and express themselves. In 1828, numerous Americans felt shocked when they heard that Jackson was running for President. Jackson was regarded by some as a "rake" or a scoundrel. One lady even cried, "Well, if Jackson can be president, anybody can!" This was indeed true. The revolution started with an overthrow of the noble republican standards by the common people. The trite people voted for "a crude frontiersman" like Andrew Jackson. They chose him over a distinguished statesman of proven ability. The years from 1828 to 1848 were known as the Age of Jackson, or the Jacksonian era. The United States had experienced many profound changes, and the arrival of thousands of new voters was to change American politics forever. Previously, only the wealthy and better educated were involved in the government. There were no political pa rties, and they were highly unaccepted by both politicians and the general public. A new generation of politicians emerged who regarded political parties more favorably. Martin Van Buren emphasized the need for a two-party system in America. He allied with John C. Calhoun and many other southern politicians. They structured a political organization around the presidential candidate Andrew Jackson. This political organization became a political party – the Democratic Party. The Democrats followed the republican beliefs of Thomas Jefferson and opposed a strong central government and also a broad interpretation of the Constitution. They had an essentially conservative political policy. Their political philosophy advocated economy in operating the government. They also wanted to eliminate the national debt, and when Jackson was president, he did eliminate the national debt in January 1835. The Democratic Party had a cent...

Identifying a Bug vs Insect
Identifying a Bug vs Insect The word bug is often used as a generic term to refer to any type of small crawling critter, and it is not only kids and unknowing adults who use the term this way. Many scientific experts, even trained entomologists, will use the term bug to refer to a wide range of small creatures, especially when they are speaking conversationally to the general public. The Technical Definition of a Bug Technically, or taxonomically, a bug is a creature that belongs to the insect order Hemiptera, known commonly as the true bugs. Aphids, cicadas, assassin bugs, ants, and a variety of other insects can claim rightful membership in the order Hemiptera. True bugs are defined by the types of mouthparts they possess, which are modified for piercing and sucking. Many members of this order feed on plant fluids, and so their mouths have the structures necessary to penetrate plant tissues. Some Hemipterans, such as aphids, can badly damage or kill plants by feeding in this way. The wings on Hemipterans, the true bugs, fold over one another when at rest; some members lack hind wings altogether. Finally, true bugs always have compound eyes. All Bugs Are Insects, but Not All Insects Are Bugs By the official definition, a large group of insects arent considered bugs, although in common usage they are often lumped together under the same label. Beetles, for example, are not true bugs. Beetles are structurally different from the true bugs of the Hemiptera order, in that their mouthparts are designed for chewing, not piercing. And beetles, which belong to the Coleoptera order, have sheath wings that form hard, shell-like protection for the insect, not the membrane-like wings of the true bugs. Other common insects that do not qualify as bugs include moths, butterflies, and bees. Again, this has to do with structural differences in the body parts of these insects. Finally, there are a number of small crawling creatures that are not insects at all, and so cannot be official bugs. MIllipedes, earthworms, and spiders, for example, do not possess the six legs and body segment structures found in insects, and are instead members of different animal orders- spiders are arachnids, while millipedes are myriapods. They may be creepy, crawly critters, but they are not bugs. Common Usage Calling all insects and all small crawling creatures bugs is a colloquial use of the term, and when scientists and otherwise knowledgeable people use the word in such a way, they are usually doing it to be down-to-earth and folksy. Many highly respected sources use the word bug when they are writing or teaching certain audiences: Gilbert Waldbauer is a respected entomologist from the University of Illinois. He authored an excellent volume called The Handy Bug Answer Book which covers everything from scorpions to silverfish.The University of Kentuckys entomology department hosts a website called the Kentucky Bug Connection. They include information on keeping pet bugs, including tarantulas, mantids, and cockroaches, none of which are actually bugs.The University of Floridas entomology department has sponsored a Best of the Bugs award honoring for outstanding insect-related websites. Among their honorees are sites on ants, beetles, flies, and butterflies- no actual true bugs.Iowa States entomology department hosts one of the best arthropod sites around- Bugguide. The site is a database of information and photographs collected by amateur naturalists, covering virtually every North American arthropod. Only a small portion of the species listed belong to the order Hemiptera. A bug is an insect, but not all insects are bugs; some non-insects that are called bugs are neither bugs nor are they insects. Is everything clear now?

Teaching Styles Essay Example | Topics and Well Written Essays - 500 words
Teaching Styles - Essay Example Students were asked to work individually on the project and had to complete two worksheets in the workbook: the â€Å"What do you know†and â€Å"What do you think†worksheets. Afterwards the class was divided into groups: each group consisted of only boys or only girls. These groups were mixed with strong and weak members and were asked to discuss and fully understand a point before continuing to the next and the teacher visited each team to ensure that each team understood what was required of them. Time was spent on a draft before commencing to the completed copy. Changes were to be made in another color or with a pen. This scenario is seen as a cooperative learning situation. Students work together in teams to complete a task; only their communication and teamwork skills will determine if their outcome will be successful. Johnson (1988) defines the word â€Å"cooperating†as â€Å"students working together in a group†. Students doing group work achieve better, as the members support and motivate each other. Learners also learn from other members’ ideas and perspectives and are more positive about school, teachers and projects. (Johnson, 1988) When working in teams learners are also more positive and that boosts their self-esteem, regardless of their abilities or background. They build on their communicative and interaction skills.

Education - Essay Example As such, the shareholders within the university system can bolster the extent to which they can engage with prospective students by applying management concepts to the way in which a defined and effective strategy can be engaged. For instance, when a strategy is put together by a group of shareholders who are not in constant communication with one another and are aware of the ultimate goal that is to be effected, a type of non specific result that does not maximize potential is almost guaranteed. However, when shareholders are brought together and the goals are clearly defined and elaborated, a type of group collaboration between all of the elements seeking to increase student attraction within the university is greatly enhanced. For this reason, understanding management concepts and the means by which collective work can be accomplished under the guiding rubric of effective management can expressly enhance the rate and effectiveness of key business level decisions. How do you think planning in today’s organizations compares to planning 25 years ago? Do you think planning become s more important or less important in a world where everything is changing fast and crises are a regular part of organization life ? Why? With regards to 25 years ago, planning has become much more integrated into the business process. For instance, 25 years ago, the rate of change that a given organization or business might experience was somewhat limited. Due to this fact, the need to expert planning was necessarily reduced as a result of the relatively slower pace that external change was exhibited within the operational environment. With regards to the importance of planning now as compared to previously, it is the strong belief of this author that the need for planning has become even stronger in a world where sudden and unexpected change can rapidly redefine the operational environment. The main reason for this is due to the fact that only through planning can the firm or e ntity hope to gain a competitive advantage and seek to anticipate some of the changes that might be upcoming in the very near future. Though one might be tempted to believe that since change is so rapid and unexpected within the current model that planning is non necessitated, the fact of the matter is that the rapid level of change implores the entity or organization to take an even more aggressive approach to planning than an environment in which change occurs slowly and gradually. For this reason, integrating an appropriate level of planning at each and every level of an organization is a primary function that can help to determine whether or not the entity will be able to survive the changes that it must integrate with. Chapter 8: Analyze three decisions you made over the past six months. Which of these were programmed and which were nonprogrammer? Which model- the classical, administrative, or political- best describes the approach you took to make each decision? The three deci sions that have been chosen for analysis within the context of this particular question are as follows: locating and renting an apartment, deciding upon what course selection would maximize efficiency, and considering picking up a minor field of study while in university. As such, all of these decisions which will be analyzed represent non-programmed choices

Galapagos Island Case Essay Example for Free
Galapagos Island Case Essay Introduction Geographical                    The geographical mapping of Galapagos Island is able to support both aquatic life and terrestrial life due to its adverse favorable climatic conditions. This is because this island lies in the Pacific Ocean about 999   km from the South American coast and straddling the Equator. Due to this smart geographical condition, there is abundant biodiversity of both flora and fauna. Galapagos Island is one of 13 islands that is currently inhabited, with a total population of 30,000 people. According to the latest survey, the Galapagos Marine Reserve occupies roughly 139,000 square kilometers. This large natural habitat can support huge mass of living creatures if protection measures are put in place to safe the endangered species. The island was recognized as world heritage site due to abundant living things that are not easily found elsewhere, but only exist in this prestigious island. Galapagos Island Biodiversity                   This island is blessed with abundant biodiversity, which enables it to have its natural heritage. Galapagos has specific niche to many unique, endemic animals. Naturally, some of these animals are fearless due to lack of natural enemies. This is a usual case for some of marine life. The only enemy is man due to his agribusiness activities and his new technologies concerning marine science, fishing and tourism. For example, the giant tortoise has gradually evolved into several distinct forms on the different islands of the archipelago. The reason being, these tortoise have no natural predators except man during the 17th and 18th centuries when buccaneers and pirates used the islands as a staging post. This is the only time when these tortoises were being used as delicacies. The Galapagos Island has several species of reptiles. They include, the marine iguana, which is a herbivore that grazes on seaweed, land iguanas, lizards, geckos, lava and snakes. Some of the native terrestrial mammals include rats that prefer grassy areas or wheat and rice plantation and two species of bat. Other common creatures are finches. There are several species of finches. Some are small brownish, soil like finches that are adapted to a range of different foods. These are known as Darwin’s finches. The name was coined after the father of evolution sir Charles Darwin because they have been important to scientists trying to study how evolution occurs this is because of different beak types. They include the tool-using woodpecker finch. Other endemic terrestrial birds include hawk, flycatcher, rail and other species of mocking birds. All these birds have specific characters that feature in them and are the only birds found in Galapagos.           Among the endemic aquatic birds are a flightless cormorant, two species of gull, and one penguin species that live in tropical waters. Going on, Sea lions and fur seals occur along the coasts, while dolphins, whales and sea turtles are also common. Other species of fish are found along the seashores. Several species of insects, cryoptera, spiders, mites, slugs, land snails, seashells, starfishes and urchins, crabs, and many other smaller invertebrates occur.             Beside different kinds of animals, the island supports different types of fauna. The plants of           Galapagos are equally fascinating and attractive. In the highlands, there occur many species of endemic Scalesia tree that is characterized by having daisies, as well as tree ferns, bromeliads and orchids. Along the coasts are mangrove forest and huge prickly pear and candelabra cacti. The Brachycereus cacti are adapted to less fertile lava flows. The lava flow is a remnant of volcanic activities that erupted in the past . Note that Galapagos Island is a product of those volcanic activities. The shores can support many vivid morning glories and mats of bright red sesuvium. Galapagos also has its very own, endemic species of cotton, tomato, pepper, guava and passionflower that are not exotic. Kinds of plants, especially those belonging to the daisy phylum, have gradually evolved on the different niche in this island into whole arrays of endemic species. This again provides bio-conservationist with classic examples of adaptive speciation. Biodiversity threats.                 Currently, the Galapagos Islands are among the best nation parks with tropical archipelago in the world. Despite being rich in its pristine nature, it faces challenges and extinction threats to the only unique type of biodiversity in the island. Actually foreign species sneaked in by naughty ship workers, pirates and other evil-minded foreigners are some of human intrusions that adversely pose a major threat to native terrestrial biodiversity. Another factor is spilling of oils in the seawater and during mosquitos’ control. Several myriad of invasive plants and animals vectored in by man’s day to days operations, inhabit the island adding more competition in the food chain. . Some of these foreign plants include food crops like quinine, guava and blackberry. In the operation process, harmful weeds and parasitic plants are introduced in new territories of this Island.            Animals in this category of invasive species include both domesticated and wild, for example, goats, Netherlands pigs, Asian dogs, cats, rats and fire ants. Some of introduced species in Galapagos Island include rodents like the black rat, Norwegian rat and house hold mouse. These rodents are disastrous as they feed on the native wildlife of the islands, including plants, seeds, bird’s eggs and chicks, reptile’s eggs and young ones. This way the rodents threaten the fragile ecosystem of the islands and are responsible for extinctions on islands biodiversity worldwide. The rodents also pose a great risk to human health by spreading zoonotic infections.[1]  Beside that, rodents are agricultural and household pests. They are vectors to fleas, worms and other protozoan. It is known that some nematodes that affect rats can invade other small animals and plants through evolution. [2]              Some species, such as the mangrove habitat birds like finch species such as C. heliobates, the Galapagos petrel and the flightless cormorant are endangered somehow due to reduced populations caused by fluctuating reproductive system. Much tourism during breeding seasons increases animal stress and disturbance. This interferes with reproductive systems. Other endemic birds in the island are the tree finches such as Certhidea olivacea and Camarhynchus psittacula.                  The Galapagos birds are already under threat from invasive rodents. The interference from both natural effects and human activities is a threat to Galapagos penguin and other aquatic bird species From a case study, it was observed that, 22 to 23.5 percent of the endemic plant species and 48.9 to 51 percent of the vertebrate species are considered endangered. Some of these problems have existed for more than a century due to negligence and ignorance by the government and other environmentalists.          Global warming which is a feature of human adverse pollution to the environment has endangered marine life. Snow and ice melting is a threat to some of marine creatures. Another threat to the biodiversity is that, Galapagos is undergoing an enormous cycle of economic and population growth that is accelerated by external markets and competition. External pressures are accompanied by increased threats to native biodiversity that drag be hide conservation efforts. Some of these threats as stated are the arrival of invasive species, over-harvesting of marine resources, for example, almost more than 90 million sharks are killed a year, mainly for their fins. They are fetched from the sea purposely for their fins and not the flesh. This barbaric altitude can wipe sharks in the near future if pouching will not stop. When sharks become wiped, tourism industry would be greatly affected making the economy of Galapagos to dwindle. Lastly, more frequent pollution events like agribusiness activities interfere with biota.  Agricultural farming involves use of several chemicals that interfere with the marine life. This mostly occurs when these chemicals find their way into the sea either by drainage or through silting.      Indirectly, enormous demand growths on the biodiversity of the islands are due to the international tourism industry and aquatic or marine resources. These are some of global factors driving business growth in Galapagos. This huge developments act as catalysts for the growth of the Galapagos human population. This has consequently, resulted to the needs for greater local access to basic natural resources and public services to catch up with the increasing human population and competition; this creates new social and political stresses in the islands. Poor distribution of resources and income from the protected areas discourages self-motive for conservation. Internal conflicts due to external market impact do not address conservation of biodiversity. Lack of awareness on importance of conservation biology in the Island, and non-instrumental professionals lead to failures to re-address the issue of endangering the species.  Conservation  methods and the needs to protecting the biodiversity.     After describing most of endangered species in this island, it is good to focus on and advocate scientific Conservation methods of both flora and fauna. Preservation of the endangered species and the environment is a complex process that requires strong machinery force. Therefore, without government and non-government back-up, this project cannot succeed. Proper programs need to be set up to outsource services and other strategic means, including funding to enhance successive conservation. In Galapagos Island, several foundations currently help to fund this project. Nevertheless, the funding is not enough to meet all the necessary measures. For example, the Galapagos Conservation project, Charles Darwin Foundation, The Galapagos Conservatory etc cannot meet these challenges without aid from donor funds. This is because to educate the whole nation about the importance of conservation, and other necessary measures is a big issue that requires donor’s aid. Actually, you should propose on external exhibitions on the needs to conserve the biodiversity, another suggestion is experienced experts need to be produced, proper fishing items that cannot fish on small or immature fishes are supposed to be bought, some motor boats should be available to control and survey fishing mechanism of both legitimate and illegitimate fishermen. Propose on preservative fringes and other necessary items bearing in mind that some items are expensive for the local people.               The government should implement measures to curtail behaviors that can lead to eradication of endangered species. These measures should include controlling pouching, smuggling, pirating and illegal immigration. In this case, Patrolling water navy and vigilante groups should be brought up in order to mitigate fishing of sharks. The use of this system for monitoring fishing vessels would enhance trapping the vessels that carry out these highly destructive fishing practices and thus provide evidence to the port police authorities so that the illegal fishing activities may be stopped. This process can only succeed with the help of local anglers of the islands and our long efforts to promote sustainable fishing practices, to limit the use of destructive fishing techniques.           Boundaries need to be restricted and observed to avoid importation of foreign organisms. This should be a foundation to remove corrupt inhabitants off the islands. People should be educated through civic education that incorporates biological and social sciences to create awareness on conservation biology. Farming methods that protect the environment should be implemented e.g. restrict any use of harmful farming methods.  Institution of higher learning should be set up to offer degree courses on conservation biology. This is because local young Ecuadorian conservationists do not have the necessary qualifications to move forward in their careers. Galapagos scientists need to be empowered with doctors of philosophy to rise to the positions of future responsibility. Surprisingly, the Charles Darwin Foundation comprises foreign scientists such as American or European as the most learned barons who cannot dedicate their service fully. The government through its own funding or by donors fund should focus on establishing environmental exhibition and communication activities. This is a valid proposal to create awareness and to inspire stewardship on Island farming and cultural behaviors that can enhance conservation. Some of the undertakings that the government should do is protecting the national parks and resorts. Furthermore, conservationist and other well-wishers have supported by saving giant tortoise from extinction. They should focus on methods of interval counting of the endangered species and reduction of their predators.            The national Park Service and the Ecuadorian government are reforming a bit of clauses that safeguard wildlife. Restrictions are imposed against the residents of the islands in the form of pouching restrictions. This include, restrict fishing within certain miles of the shores and out of the swimming patterns of the endangered species in the islands. It is also illegal on the island to hunt any terrestrial animals and the offence is jail term and revocation of the citizenship on the island. These are among the tough measures that ministry of wild life in conjunction with the environmentalist are imposing to conserve the endangered species. You should pressurize on review of important sections in the country constitution that safeguard the wild life. Some nuisance pests need to be eradicated for example, rats, parasitic weeds and plants, since some fish such as sharks suffer from animal stress due to tourism visitors. These areas have been classified as non-go zones, which mean that the number of motor boats and visitors in the water can be regulated. However, many areas have still to be restricted. People should be sensitized on zonotic infections caused by some of these foreign organisms. Funding to help identification of breeding zones for sharks and the monitoring of population increase in coastal areas are important areas of research that can aid in conservation. Breeding and nestling parameters, which are essential for shark conservation, are not yet understood. In case of preserving sharks that attract a lot of tourism, conservation funds would assist in monitoring and identifying sharks movements and breeding patterns. Eradication of animals and plants, which pose a threat to the existing of the eco system, is a noble idea that is facilitated by the National Park service.                             Conclusion.         Conservation biology in the Galapagos is important because the work done by the Galapagos National Park to protect the biodiversity of the Galapagos Islands is unique. What to protect and the methods to be used depend on scientific knowledge and government back up. This will include careful study, research and interpretation of existing data on wildlife. The funding requested will be required to help local residents to become a leader of their own future. Without the necessary research, awareness, funds and dedication provided by the Galapagos Conservation Trust, this valuable habitat and its unique wildlife will become a history.       The fact is extinction would be due to human intrusion. This adversely leads to loss of biodiversity. The consequences are loss of marine life and disappearance of native terrestrial animals and plants.  Many species of wildlife will be extinct, species that have been a pivotal point in the discovery of natural selection. The advancement of these studies that is so important to science will be lost. There are many species in Galapagos Islands that are not analyzed. The destruction of the sensitive ecosystem could destroy these species forever.  Apparently, tourism sector would be greatly affected this Island biodiversity becomes extinct. Tourism is growing at an enormous rate of 4% per year and is expected to continue at this rate. The need for support functions in the industry continues to provide significant job opportunities for the local residents. Indirectly, the national economy would be greatly affected hence currency fluctuation and instability.        To avoid this disastrous situation, conservation biology should be addressed from all perspective.

A Comparison of A Midsummer Nights Dream and Romeo and Juliet Essay
Parallel Themes and Characters in A Midsummer Night's Dream and Romeo and Juliet Certain parallels can be drawn between William Shakespeare's plays, "A Midsummer Night's Dream", and "Romeo and Juliet". These parallels concern themes and prototypical Shakespearian character types. Both plays have a distinct pair of 'lovers', Hermia and Lysander, and Romeo and Juliet, respectively. Both plays could have also easily been tragedy or comedy with a few simple changes. A tragic play is a play in which one or more characters has a moral flaw that leads to his/her downfall. A comedic play has at least one humorous character, and a successful or happy ending. Comparing these two plays is useful to find how Shakespeare uses similar character types in a variety of plays, and the versatility of the themes which he uses. In "Romeo and Juliet", Juliet is young, "not yet fourteen", and she is beautiful, and Romeo's reaction after he sees her is, "O, she doth teach the torches to burn bright! It seems she hangs upon the cheek of night As a rich jewel in an Ethiop's ear Beauty to rich for use, for the earth too dear!" Juliet is al... ..., not because one character has a flaw, but both families have a flaw- pride. Prohibited love, romance, controlling families, both plays have it all. With a few simple modifications, "A Midsummer Night's Dream" could have been a tragedy, and "Romeo and Juliet" could have been a comedy. Shakespeare however, uses many of the same character types, young, prudent, rebellous lovers, and controling family members, in both comedies and tragedies. The end results are character molds, along with theme molds that can be easily translated into almost any plot, in any play.

Can Public Relations Be Ethically Moral
Can public relations be ethically moral? Should we be involved in them if we want to be moral individuals? But what is ethical, moral and what is already unethical, immoral? Where are the frontiers? And who define them? The Internet Encyclopedia of Philosophy explains: â€Å"The field of ethics, also called moral philosophy, involves systematizing, defending, and recommending concepts of right and wrong behavior†(http://www. iep. utm. edu/e/ethics. htm). All definitions of ethics usually share certain notions such as distinguishing right from wrong, and determining the nature of what should be valued. In the public relations discipline, ethics embraces values like honesty, openness, loyalty, fair-mindedness, respect, integrity, and forthright communication. But people do not consider it in order life . Public relations are often immoral. Everybody wants the best for himself and people are hell-bent for everything. They use different methods to gain it. A man behaves often like a wild animal in a jungle. Thus if you want to survive you have to follow. You have to take the rules of the majority. And unfortunately, these rules are not always in accordance with ethics. The frontiers of ethic have moved only because our society lets them. What used to be immoral in the past, is considering normal today. There is no right way how to avoid immorality in public relations. The question is, how strong it is and will become. The answer will primarily depend on the society and its future action in moving the frontiers of ethics.

All Windows computers including those running Windows 10 come with a program called Notepad that creates and modifies plain-text documents. Saving PHP Documents In your text editor, just save the PHP source code with a PHP extension. Windows may or may not recognize PHP as a valid system file type, but it doesnt matter. You generally dont want Windows to attempt to execute a PHP script. You could, however, associate PHP as a file type that your favorite text editor manages, so double-clicking a PHP file will open it in that editor. Media Files Saved as PHP Some browser plugins that download media from web pages will incorrectly capture the media files correct extension. The file will save with the correct name, but with a PHP extension. This glitch occurs only occasionally and stems from the media file sourcing from a PHP-enabled page. All you need to do is change the PHP extension to something like MP4. Video-playback programs like VLC accept the MP4 extension without complaining, even if the underlying video type is something else. Writing PHP Unlike some programming and scripting languages, PHP is not sensitive to indentations. Therefore, any indentations you make to your PHP code to aid your readibility are fine. Other Programs to Edit PHP Files Notepad is simple, but its not the only choice. Mac users can use TextEdit. Hardcore programmers (usually, on Linux) rely on environments like Emacs or Vim. Better than using a text editor - which, by design, just edits text, without additional functionality - is to use a text editor optimized for coding. On the Windows platform, programs like Visual Studio Code, BB Edit, UltraEdit, and Notepad not only edit your text but can lint (analyze for errors) and format your code with special colors and related visual cues.

Biography of Tipu Sultan, the Tiger of Mysore
Biography of Tipu Sultan, the Tiger of Mysore Tipu Sultan (November 20, 1750–May 4, 1799) is remembered by many in India and Pakistan as a heroic freedom fighter and warrior-king. He was the last ruler in India strong enough to dictate terms to the British East India Company. Known as the Tiger of Mysore, he fought long and hard, although ultimately unsuccessfully, to preserve his countrys independence. Fast Facts: Tipu Sultan Known For: He is remembered in India and Pakistan as a warrior-king who fought brilliantly for his countrys independence from Britain.Also Known As: Fath Ali, Tiger of MysoreBorn: November 20, 1750 in Mysore, IndiaParents: Hyder Ali and Fatima Fakhr-un-NisaDied: May 4, 1799 in Seringapatam, Mysore, IndiaEducation: Extensive tutoringSpouse(s): Many wives, including Sindh Sahiba Children: Unnamed sons, two of whom were held hostage by the BritishNotable Quote: To live like a lion for a day is far better than to live for a hundred years like a jackal. Early Life Tipu Sultan was born on November 20, 1750, to military officer Hyder Ali of the Kingdom of Mysore and his wife, Fatima Fakhr-un-Nisa. They named him Fath Ali but also called him Tipu Sultan after a local Muslim saint, Tipu Mastan Aulia. His father Hyder Ali was an able soldier and won such a complete victory against an invading force of Marathas in 1758 that Mysore was able to absorb the Marathan homelands. As a result, Hyder Ali became the commander-in-chief of Mysores army, later the Sultan, and by 1761 he was the outright ruler of the kingdom. While his father rose to fame and prominence, young Tipu Sultan was receiving an education from the finest tutors available. He studied such subjects as riding, swordsmanship, shooting, Koranic studies, Islamic jurisprudence, and languages such as Urdu, Persian, and Arabic. Tipu Sultan also studied military strategy and tactics under French officers from an early age, since his father was allied with the French in southern India. In 1766 when Tipu Sultan was just 15 years old, he got the chance to apply his military training in battle for the first time when he accompanied his father on an invasion of Malabar. The youngster took charge of a force of 2,000-3,000 and cleverly managed to capture the Malabar chiefs family, which had taken refuge in a fort under heavy guard. Fearful for his family, the chief surrendered, and other local leaders soon followed his example. Hyder Ali was so proud of his son that he gave him command of 500 cavalries and assigned him to rule five districts within Mysore. It was the start of an illustrious military career for the young man. First Anglo-Mysore War During the mid-18th century, the British East India Company sought to expand its control of southern India by playing local kingdoms and principalities off one another and off the French. In 1767, the British formed a coalition with the Nizam and the Marathas, and together they attacked Mysore. Hyder Ali managed to make a separate peace with the Marathas, and then in June he sent his 17-year-old son Tipu Sultan to negotiate with the Nizam. The young diplomat arrived in the Nizam camp with gifts that included cash, jewels, 10 horses, and five trained elephants. In just one week, Tipu charmed the ruler of the Nizam into switching sides and joining the Mysorean fight against the British. Tipu Sultan then led a cavalry raid on Madras (now Chennai) itself, but his father suffered a defeat by the British at Tiruvannamalai and had to call his son back. Hyder Ali decided to take the unusual step of continuing to fight during the monsoon rains, and together with Tipu he captured two British forts. The Mysorean army was besieging a third fort when British reinforcements arrived. Tipu and his cavalry held off the British long enough to allow Hyder Alis troops to retreat in good order. Hyder Ali and Tipu Sultan then went on a tear up the coast, capturing forts and British-held cities. The Mysoreans were threatening to dislodge the British from their key east coast port of Madras when the British sued for peace in March 1769. After this humiliating defeat, the British had to sign a 1769 peace agreement with Hyder Ali called the Treaty of Madras. Both sides agreed to return to their pre-war boundaries and to come to each others aid in case of attack by any other power. Under the circumstances, the British East India Company got off easy, but it still would not honor the treaty terms. Interwar Period In 1771, the Marathas attacked Mysore with an army perhaps as large as 30,000 men. Hyder Ali called upon the British to honor their duty of aid under the Treaty of Madras, but the British East India Company refused to send any troops to assist him. Tipu Sultan played a key role as Mysore fought off the Marathas, but the young commander and his father never trusted the British again. Later that decade, Britain and France came to blows over the 1776 rebellion (the American Revolution) in Britains North American colonies; France, of course, supported the rebels. In retaliation, and to draw off French support from America, Britain had decided to push the French entirely out of India. In 1778, it began to capture key French holdings in India such as Pondicherry, on the southeastern coast. The following year, the British grabbed the French-occupied port of Mahe on the Mysorean coast, prompting Hyder Ali to declare war. Second Anglo-Mysore War The Second Anglo-Mysore War (1780–1784), began when Hyder Ali led an army of 90,000 in an attack on the Carnatic, which was allied with Britain. The British governor at Madras decided to send the bulk of his army under Sir Hector Munro against the Mysoreans, and also called for a second British force under Colonel William Baillie to leave Guntur and meet up with the main force. Hyder got word of this and sent Tipu Sultan with 10,000 troops to intercept Baillie. In September 1780, Tipu and his 10,000 cavalry and infantry soldiers surrounded Baillies combined British East India Company and Indian force and inflicted on them the worst defeat the British had suffered in India. Most of the 4,000 Anglo-Indian troops surrendered and were taken prisoner, while 336 were killed. Colonel Munro refused to march to Baillies aid, for fear of losing the heavy guns and other material he had stored. By the time he finally set out, it was too late. Hyder Ali did not realize just how disorganized the British force was. Had he attacked Madras itself at that time, he likely could have taken the British base. However, he only sent Tipu Sultan and some cavalry to harass Munros retreating columns. The Mysoreans did capture all of the British stores and baggage and killed or wounded about 500 troops, but they did not attempt to seize Madras. The Second Anglo-Mysore War settled down into a series of sieges. The next significant event was Tipus February 18, 1782 defeat of East India Company troops under Colonel Braithwaite at Tanjore. Braithwaite was completely surprised by Tipu and his French ally General Lallà ©e and after 26 hours of fighting, the British and their Indian sepoys surrendered. Later, British propaganda said Tipu would have had them all massacred if the French hadnt interceded, but that is almost certainly false- none of the company troops were harmed after they surrendered. Tipu Takes the Throne While the Second Anglo-Mysore War was still raging, the 60-year-old Hyder Ali developed a serious carbuncle. His condition deteriorated throughout the fall and early winter of 1782, and he died on December 7. Tipu Sultan assumed the title of Sultan and took his fathers throne on December 29, 1782. The British hoped that this transition of power would be less than peaceful so that they would have an advantage in the ongoing war. However, Tipus smooth transition and immediate acceptance by the army thwarted them. In addition, British officers had failed to secure enough rice during the harvest, and some of their sepoys were literally starving to death. They were in no condition to launch an attack against the new sultan during the height of the monsoon season. Settlement Terms The Second Anglo-Mysore War went on until early 1784, but Tipu Sultan maintained the upper hand throughout most of that time. Finally, on March 11, 1784, the British East India Company formally capitulated with the signing of the Treaty of Mangalore. Under the terms of the treaty, the two sides once again returned to the status quo in terms of territory. Tipu Sultan agreed to release all of the British and Indian prisoners of war he had captured. Tipu Sultan the Ruler Despite two victories over the British, Tipu Sultan realized that the British East India Company remained a serious threat to his independent kingdom. He funded continuous military advances, including further development of the famous Mysore rockets- iron tubes that could fire missiles up to two kilometers, terrifying British troops and their allies. Tipu also built roads, created a new form of coinage, and encouraged silk production for international trade. He was particularly fascinated and delighted with new technologies and had always been an avid student of science and mathematics. A devout Muslim, Tipu was tolerant of his majority-Hindu subjects faith. Framed as a warrior-king and dubbed the Tiger of Mysore, Tipu Sultan proved an able ruler in times of relative peace as well. Third Anglo-Mysore War Tipu Sultan had to face the British for a third time between 1789 and 1792. This time, Mysore would receive no aid from its usual ally France, which was in the throes of the French Revolution. The British were led on this occasion by Lord Cornwallis, one of the major British commanders during the American Revolution. Unfortunately for Tipu Sultan and his people, the British had more attention and resources to invest in southern India this time around. Although the war lasted for several years, unlike past engagements, the British gained more ground than they gave. At the end of the war, after the British besieged Tipus capital city of Seringapatam, the Mysorean leader had to capitulate. In the 1793 Treaty of Seringapatam, the British and their allies, the Maratha Empire, took half of the territory of Mysore. The British also demanded that Tipu turn over two of his sons, ages 7 and 11, as hostages to ensure that the Mysorean ruler would pay war indemnities. Cornwallis held the boys captive to ensure that their father would comply with the treaty terms. Tipu quickly paid the ransom and recovered his children. Nonetheless, it was a shocking reversal for the Tiger of Mysore. Fourth Anglo-Mysore War In 1798, a French general named Napoleon Bonaparte invaded Egypt. Unbeknownst to his superiors in the Revolutionary government in Paris, Bonaparte planned to use Egypt as a stepping-stone from which to invade India by land (through the Middle East, Persia, and Afghanistan), and wrest it from the British. With that in mind, the man who would be emperor sought an alliance with Tipu Sultan, Britains staunchest foe in southern India. This alliance was not to be, however, for several reasons. Napoleons invasion of Egypt was a military disaster. Sadly, his would-be ally, Tipu Sultan, also suffered a terrible defeat. By 1798, the British had had sufficient time to recover from the Third Anglo-Mysore War. They also had a new commander of British forces at Madras, Richard Wellesley, Earl of Mornington, who was committed to a policy of aggression and aggrandizement. Although the British had taken half of his country and a large sum of money, Tipu Sultan meanwhile had rebuilt significantly and Mysore was once more a prosperous place. The British East India Company knew that Mysore was the only thing standing between it and total domination of India. A British-led coalition of nearly 50,000 troops marched toward Tipu Sultans capital city of Seringapatam in February 1799. This was no typical colonial army of a handful of European officers and a rabble of ill-trained local recruits; this army was made up of the best and brightest from all of the British East India Companys client states. Its single goal was the destruction of Mysore. Although the British sought to enclose Mysore state in a giant pincher movement, Tipu Sultan was able to sally out and stage a surprise attack early in March that nearly destroyed one of the British contingents before reinforcements showed up. Throughout the spring, the British pressed closer and closer to the Mysorean capital. Tipu wrote to the British commander Wellesley, trying to arrange for a peace agreement, but Wellesley deliberately offered completely unacceptable terms. His mission was to destroy Tipu Sultan, not to negotiate with him. Death At the beginning of May 1799, the British and their allies surrounded Seringapatam, the capital of Mysore. Tipu Sultan had just 30,000 defenders matched against 50,000 attackers. On May 4, the British broke through the city walls. Tipu Sultan rushed to the breach and was killed defending his city. After the battle, his body was discovered beneath a pile of defenders. Seringapatam was overrun. Legacy With Tipu Sultans death, Mysore became another princely state under the jurisdiction of the British Raj. His sons were sent into exile, and a different family became puppet rulers of Mysore under the British. In fact, Tipu Sultans family was reduced to poverty as a deliberate policy and was only restored to princely status in 2009. Tipu Sultan fought long and hard, although ultimately unsuccessfully, to preserve his countrys independence. Today, Tipu is remembered by many in India and Pakistan as a brilliant freedom fighter and as an able peacetime ruler. Sources Britains Greatest Foes: Tipu Sultan.

The corporate scandals are usually perpetrated by several people who understand the organization’s every single detail, with most collaborating parties being people with high standing in the society. Most executives in failed corporations admit receiving enormous bonuses and backdated stock options to warrant that they will make wealth from investing in their company; not considering whether their performance made the share price increase or go down. Other unethical behaviors have resulted in the downfall of corporations, poor performance and negative publicity. As a result, the aspect of ethics in organizations has increasingly gained prominence due to distrust on organizational leaders (Loe, Ferrell & Mansfield, 2000) This study seeks to examine some of th e corporate failures, reasons behind their fall, as well as a close examination as to where blame may be assigned. Of specific importance, Enron downfall and Satyam scandals will be useful in examining ethics behind corporations’ failure. The paper will also look at the theories that expound on the subject of ethical governance in organizations. Ethics is a significant pillar in the modern corporate arena and corporate governance. Organizations have learnt useful lessons from the above cases on the danger that unethical decisions can bring in any organizations. As David Thoreau once said, â€Å"it is truthfully sufficiently said that a firm has no conscience; but a company of conscientious men is a corporation with ethics†. This statement carries a lot of meaning with it as to the significance of upholding ethics in organizations. The subject of what constitutes ethical behavior in organizations remains a debatable subject due to the wide ranging opinions of what const itutes ethics, and what ethics is not. Nevertheless, many organizations have embraced ethical codes stating their leading philosophical guidelines and organizational values. Ethical codes that are successful highlight the obligations of organizations to shareholders, the behavior anticipated of employees, and ethical parameters of the organization. Ethical codes are intended to impact on employee behavior, and are also referred to as corporate ethics statements. Business ethics field deals with questions as to whether a particular business practices are acceptable. Controversial business ethics issues arise on a daily basis in every organization, and this calls for organizational members to exercise their conscience as Thoreau said. For illustration, an accountant may face an ethical dilemma in his/her course of duty that may compromise her decision. For instance, if an accountant discovers inaccuracies in a client’s auditing report, he/she may opt to report the inaccuracy. O n the other hand, reporting such an inadequacy may result in the auditing company fired by the client for disclosing the inadequacies. This confusion leaves the accountant at crossroads as to what practice is acceptable. Business ethics require that organizational members to conform to sound moral principles. Special consideration has to be put into perspective when applying the concept of ethics in business. One is that businesses are formed with the aim of making a profit, and therefore, businesses
