Mariculture Essays - Aquaculture, Fisheries, Mariculture, Oyster

Mariculture Mariculture As the Spanish entered the capital city of Tenochtitlan they were astounded at the many marvels of the city but one of the things that most caught the eyes of the foreigners was the extensive plant growth on the lake surrounding the city. These images were describe the among the first recorded descriptions of large scale mariculture. Mariculture, or aquaculture, refers to the rearing of the aquatic organisms under controlled or semicontrolled conditions. Although there is a simple difference between the two, aquaculture generally refers to the exploitation of freshwater fish and mariculture more generally refers to the culture and farming of marine organisms. Simply put mariculture is underwater agriculture. There are many possibilities for the realm of mariculture, it has the potential to be a great help in the production of the food supply in the world. Mariculture is not a new development in mankinds history but it is a largely ignored form of food production. In a broad sense mariculture includes the rearing of tropical fishes, the production of minnows, koi, and goldfish; the culture of sport fishes for stocking into farm ponds, streams, reservoirs, and even the ocean; production of animals for augmenting commercial marine fisheries; and the growth of aquatic plants. Mariculture is a myriad of possibilities that involve organisms and the seas. The history of mariculture can be traced back way into the past, the Greeks and Romans were known to have fattened fish in ponds and Egyptian carvings suggest that the Egyptians may have practiced it as well. So we know that the potential for the exploitation has been there for a very long time. Why then has this type of food procurement not been used more extensively? There can be a few good reasons for this such as the availability of technologies, the difficulty of harvesting the seas, and the knowledge of the workings of the sea in order to fully use the capabilities of the ocean. We now have the technology, knowledge, and capability to successfully implement large scale mariculture. Historians say that agriculture made it possible for man to grow and expand as it has done over the last few thousand years so now one can wonder what the future holds if and when mariculture is implemented into the everyday workings of society. Could it be the next giant leap for mankind? There are many different methods to mariculture. For the most part mariculture entails the confinement of fish to earth ponds, concrete pools, or cages suspended in open water. In these enclosures, the fish can be supplied with adequate food and protected from natural predators. Some of the most common methods for mariculture are transplantation, hatchery stocking, and enclosures and retainers. Transplantation involves the movement of fish populations from a good fishing area to a location that does not exhibit a great fishing catches. In this way areas of low fish concentration are injected with an influx of fish that help to make the average much higher and thereby bring the overall population to a higher state. The next method of mariculture is hatchery stocking this process happens when people create a safe environment such as tanks, pools, or concrete or earth ponds into which they pour fish eggs. These eggs are cared for and are provided with the essential things such as nutrients and correct temperatures in which to thrive. The fish are born and raised to a certain stage and then are moved to open waters or such places as lakes, streams, and ponds. In this way these habitats are provided with ample supplies of fish and other marine organisms. Another method involves the use of enclosures and retainers. This certain method can be described in three separate ways, natural feed, supplemental feed, and no natural feed. The natural feed method works by separating the desired fish and the food providers of the fish from there predators in there own natural waters by the use of netted embayments and cages, thereby allowing the provider to grow and multiply in its own habitat and this in turn a llows the fish to multiply. The second way is supplemental feed and this method works by isolating fish in tanks or concrete ponds. In

Dr. Kings Letter From Birmingham Jail essays

Dr. King's Letter From Birmingham Jail essays "Nonviolence can touch men where the law cannot reach them." These words, as spoken by the late civil rights leader Dr. Martin Luther King Jr. (Stride Toward Freedom: The Montgomery Story, 1958) became the fundamental tenet of his life. The concept behind the words would define not just his work, but the history of an entire generation of American people in the middle of the 20th century. But his words would have proven hollow were it not for the actions that he took to support them. If his words were the spike that pierced the heart of segregation, the nonviolent demonstrations that accompanied them were the hammer that was struck against that spike. They were a forceful combination that couldnt be ignored or muted through the stubborn efforts of segregationists of the time. Dr. Kings words informed his actions, and vice-versa. Nowhere in his great history is that more evident than in the seemingly personal letter he wrote from a jail cell in Alabama; the Letter from Birmingham Jail . A key example of this in Letter from Birmingham Jail is found in a section in which Dr. King says, I have consistently preached that nonviolence demands that the means we use must be as pure as the ends we seek. (Paragraph 43). At this particular point of Kings letter, there are various underlying meanings and interpretations that may be gleaned, but they all strike the same chord. Whereas the old adage states that the ends justifies the means, nonviolence and particularly its use during the Civil Rights Movement, dictates that the means should justify the ends. The words, and the meanings within them, are held as an ideology; a mission statement for the entire Civil Rights Movement and the moral standard of the individual persons. To be more specific about what this means, Dr. Kings testament of nonviolence spoke to the cause and fight against legal and social injustice, provided a stark cont...

Solid Waste Management Privatization Research Paper

Solid Waste Management Privatization - Research Paper Example This research paper not only discusses today's pollutive levels in India, but also analyzes benefits and disadvantages of privatizing solid waste management services in New Delhi. The researcher explores costs of waste disposal services in India, that had increased from 21 to 42% after the privatization. This drop in costs was mainly attributed to great efficiency and stricter monitoring of the waste services. The government, on the other hand, cannot pay its workers lower than their minimum, therefore without privatization the costs will still remain high. In their provision of services, private companies also have economies of scale to protect the environment and to get into multiple contracts thus, incurring very low costs. In addition this research paper also discusses government bureaucracies, such as service limitations, that are not imposed on private companies and for this reason, their service provision is not hindered at all. Privatization of solid waste management was also thought as beneficial by the researcher due to the increased efficiency of the services. The dumping sites in New Delhi reduced remarkably after the privatization program. In conclusion, the researcher states that privatization of solid waste management certainly has more benefits than if left in the hands of the public sector. Better and improved results are more likely to be obtained if the private sector undertakes the solid waste management services. However, the cost factor is still of great importance.

Scientific Concept Research - Essay Example The process we call recycling is the act of making used materials into other forms of materials that will benefit the end user and the environment we live in. Everyday we live on resources and produce waste after consumption. However, millions of individuals neglect these waste materials and do not realize their worth for other functions in our environment. So one question comes to our mind, why is recycling important? An old saying goes, â€Å"it’s easier said than done.† I have seen hundreds of world leaders talk about recycling, making our earth a greener place to live in etc. but they have never successfully campaigned for recycling. As soon as they newly elected officers sit on their desk, they forget about their vision and just ride along the power trip. For me, recycling is very essential to us, human beings, because it affects not only ourselves but also our future generations to come. We must preserve the beauty of our environment for our children to see as well. The thought in recycling is comparable to the thought of reincarnation in the Christian bible. As our human bodies decay and our souls depart, we are reborn into other creatures or species and form part of society in a different perspective. When we pass away, our spirit is reborn into a different being. We may be a dog, cat, or insect in the next life. Recycling does the same function through a cycle of waste to a new form of use in society. Science tries to explain the importance of recycling because our world does not have unlimited resources. By providing an alternative of producing new light from garbage, we are able to save nature and preserve it. We can compare recycling to religious practice because religion observes certain rituals and traditions to nurture their beings. Almost any church needs rituals and weekly collection (Ackerman, 1997). They collect resources and impose a â€Å"bringing back to life† of used resources such as

China Assignment Example | Topics and Well Written Essays - 750 words

China - Assignment Example The emperor created an intricate bureaucracy which they used to wage imperial wars, perform public works projects and to build large temples. During the Imperial era, the states were centralized though local officials maintained limited autonomy. Artisans and self-sufficient peasant farmers ruled the economy during this period. Business was relatively frequent and it increased after the Han Dynasty after Silk Road was developed. During this period, there was an emergence of large-scale businesses and advancements in technology. Developments in technology were marked by the invention of paper, wheelbarrows and the seismograph. The Late Imperial era brought an economic revolution in China. With technological advancements, there was a rise in large-scale enterprises, waged labour and use of paper money. Trade in the overseas flourished during the Ming Dynasty. Liberalisation of capital, investment and commerce took place as technology continued to advance. At the same time, there was privatisation of government manufacturing industries. There was also emergence of urban and rural markets, whereby there was production that was geared towards consumption. The emergence of these markets was a key development during this era (Hampton & Moss, 2004, p. 37-42). Power distance refers to the extent to which people who have less powers in an organization will expect and accept power to be distributed in a different way. China is ranked 80 on power distance which is very high. This rank means that there is a big power distance between the subordinates and the management. However, that is acceptable and considered normal. Individualism is where people think with a mentality of â€Å"I† or â€Å"We†. For the American culture for example, it is mostly â€Å"I† focused. It therefore means that the Americans focus more on furthering themselves and their careers versus furthering their departments or groups. China is ranked at 91 on individualism. It therefore means

Electoral systems in the UK and US

Electoral systems in the UK and US The United States of America and Great Britain have a lot of in common but the same times have a number of differences. The electoral systems of the UK and the US differ a lot. The United Kingdom uses different electoral systems and among them we could mention.  First Past the Post, which is used for the whole national elections and also when the local government is elected in England and Wales (earlier it was used in Scotland too). Additional Member System was invented after submission of the regional devolution in 1999 for the Scottish Parliament, Welsh meeting and London meeting.   It is rather modern invention, which was undertaken after electoral system reform.   Single Transferable Vote system is used for the election into the Assembly of the Northern Ireland and also is used for the Local administration.  Party Lists are used for the elections to the European Parliament and that is also rather modern invention and applied as the UK is the member of the European Union. And finally, Supplementary Vote, is used for the mayors election in the different cities, for example London. We see that the electoral system of the United Kingdom is rather complicated and strongly depends on the territorial division of the country. It should be noted that the United States is also dependent on the territorial division and each state has its constitutional and the elections to the local governmental organs are held due the legislation of the each state. But if we speak about electoral system globally we should mention about the Primaries, which are used for the President elections. This the first type of the election, when one candidate from the party is elected. Between the chosen candidates the general election is held and the core idea of the Primaries is in the fact that candidates from different parties should not take the votes of each other on the main elections, as their electorate is quite the same target group. Sometimes those who have lost the primaries took part in the president elections, but as independent candidates, without support of their party. Primaries could be opened, when everyone could take part in the elections and closed, when the members of the party, holding the primaries, could vote. The Primaries are the core peculiarity of the United States electoral system. It should be noted that a number of states refused from primary use of the Primaries. The different system are used for counting the votes and different schemes. A number of southern states have a tradition to support the candidate, which would take the arithmetic majority of the votes. In southern states the break between the winner and the nearest competitors. It should be noted that the both systems differ a lot and the United Kingdom has developed the electoral systems suitable for their political structure and the United States for theirs. I think that the core role in the difference between these states is that they have different political structure and this causes so severe difference in their electoral structure.   References: Michael Thrasher and Colin Rallings.

The Divine Comedy: Dante Essay examples -- essays research papers

The Divine Comedy: Dante   Ã‚  Ã‚  Ã‚  Ã‚  The character of Dante in The Divine Comedy who descended into the inferno caused me to stop and think about this awful place. As the reader I got to take an imaginary journey with Dante to a horrible place where I do not care about going. While Dante descended into hell I plan on ascending into heaven someday. Dante had a choice to make whether or not to get back on the right path. It came down to heaven or hell - choose.   Ã‚  Ã‚  Ã‚  Ã‚  I think it was willed for Dante to see this place while he was still living. By seeing hell while he was alive Dante could be sure and make the right choices to find his way back to the straight path. Being on the right path in his lifetime would ensure he would not spend eternity in such a miserable place. I believe the whole purpose of this journey into hell was to let Dante see the anguish there and choose. Perhaps this was a divine warning. In Canto 2, Beatrice, the symbol of Divine Love, an angelic spirit was sent to help aid Dante from his error and help him return back. This is purely love and compassion at its best. Sending someone into hell to rescue another person out of there. Great lengths were taken to help Dante return back to the straight way. I do not believe such action was taken if Dante was to end up in hell all along.   Ã‚  Ã‚  Ã‚  Ã‚  For some reason midway in Dante's life's journey he had gone astray and at this point was searching for...

Board Game and Total Cycle Time

X-Opoly Inc. X-Opoly, Inc. , was founded by two first-year college students to produce a knockoff real estate board game similar to Monopoly. Initially, the company’s purpose was to produce a board game based on popular local landmarks in their small college town, as a way to help pay for their college expenses. However, due to big success and since they enjoyed running their own business, the founders decided to pursue the business full-time after graduation.X-Opoly has growth over the last couple of years attributed to its designing and producing custom real estate trading games for universities, municipalities, chambers of commerce, and lately even some businesses. The company fills orders from a couple of hundred to several thousand and projects that its sales will grow 25 percent annually for the next five years. X-Opoly’s Process X-Opoly’s clients request either a new game board that has not been produced or repeat orders for a game that was previously prod uced.Once the request for a new game is received from a client, a meeting is arranged with a graphic designer from X-Opoly’s art department and the actual game board is designed. The approved designs are transferred electronically to the printing department where they are loaded onto personal computers and printed on special decals. The printing department is also responsible for printing the property cards, game cards, and money. The money is then moved to the cutting department, where it is cut into individual bills. Similarly, property cards and game cards are produced with the exception of using material resembling poster board.In addition to cutting the money, game cards, and property cards, the cutting department also cuts the cardboard that serves as the substrate for the actual game board. After being cut, game boards, money, and cards are stored in totes in a work-in-process area and delivered to the appropriate station on the assembly line as needed. X-Opoly Operati ons Efficiency Measuring X-Opoly’s performance is the key to improving its service to customers. The company currently operates 19 stations with a total cycle time of 6 min 45 sec per job.In my opinion, X-Opoly should consider combining assemblies within stations to reduce the number of stations. This process would allow some components to be partially assembled for the next station. This reduces the number of jobs involved in making multi-level products and keeps inventory to a minimum. Adopting a lean approach starts with a simple question: â€Å"What's essential? † Whether X-Opoly is simply trying to survive or conducting an assessment of their productivity, it is imperative to determine that every activity they engage in is essential in the value chain to providing a competitive product.This involves analyzing each phase of the product lifecycle from innovation, to design and development, to testing and, eventually, manufacturing and removing the waste from those p rocesses. For example, the company’s production line maximum capacity/day is would increase by reducing the waste and redundancy in design and development which would increase the company’s efficiency. To further improve X-Opoly’s efficiency, I would recommend developing a more formal manufacturing system (Flow Manufacturing). Flow manufacturing is a time-based process that pulls material through a production system without any interruption. (SAE. rg) This can be achieved by striking the proper balance between new technology and the proper amount of skilled labour. Flow manufacturing would reduce total cycle time, lessen inventory and increase X-Opoly’s productivity. The increase productivity would assist the company in meeting and possibly exceeding future demands. Finally, I believe X-Opoly would benefit from eliminating is non value added time to improve its efficiency. References Jacobs, F. , and Chase, R. , (2011).

Aviation Safety Program Management Example

Aviation Safety Program Management Example Aviation Safety Program Management – Article Example Aviation Safety Management Program Aviation Safety Management programs are being applied in various aviation industriesworldwide. There are various changes taking place in the aviation industry to ensure that the national airspace meets the future customer demands (SkyBrary, 2012). The transport system is undergoing various changes to ensure that the overcrowded skies facilitate speed and efficiency while ensuring safety of the skies. Safety Management Programs in the aviation industry are measure or principles that are aimed at reducing injuries accruing from accidents due to the use of a product or service (Byron, 2007). In USA, the Federal Aviation Administration is tasked with carrying out inspections of the aviation businesses to ensure that the safety measures are implemented. This paper will focus on discussing the aviation safety management program and its application in today’s industry.In 2011, various industries in the aviation industry faced fines due to non compli ance to the aviation safety program. FAA proposed a fine of about $625,000 on Pinnacle which is a regional affiliate airline of Delta Airline (SkyBrary, 2012). FAA accused the airline of using their regional jet for local flights after a flight crew rather than a maintenance crew performed maintenance tasks on the jet. FAA also alleged that the company used the Canadair regional jet without inspecting the crack on the casing around the engine. Due to this, size of the crack had increased in size and posed a risk to the safety of customers and the American skies. In its defense, the airline management maintained that they ensured that the right staff did their job. They also claimed that safety was one of their priorities (Byron, 2007).The ICAO Safety Management Manual (Doc 9859) identifies two types of safety management programs applicable in the aviation industry. This includes the reactive (traditional) and proactive (modern) safety management programs (SkyBrary 2012). The reactiv e safety management program is used when dealing with technological failures. This program aims at achieving the levels of reported safety levels. On the other hand, the proactive safety programs aim at identifying the hazard before they materialize into a disaster. It also encompasses measure taken to reduce the safety risk.Reference ListByron, B. (2007). Safety Management Systems. Flight Safety Australia,13 (4), 319-335.

Everything You Need To Know About Feature Stories

Everything You Need To Know About Feature Stories Writing A Feature Story: What To Remember It is a well-known fact that students and even journalists find first feature stories one of the most difficult task throughout their educational or professional life. The writing process involves lots of data, honesty, tact and integrity. You need to depict a certain person to the audience, giving him or her enough credits and presenting in an unbiased way. That is why feature stories often ask the author to do something almost impossible: to get familiar with the person, appreciate personal treats of character, conduct an interview, hold a personal meeting and then write an article, which shouldn’t be all positive and nice. Remember, you are a subjective author and not a cheerleader of a described person. So how is it possible to balance everything? We have collected the six most important steps, which you will need in creating a feature story. With practice and devotion come great results, so take your time and you will surely succeed! Choose a subject, which will be interesting for the reader As you already know, choosing an interesting and timely topic for an assignment is the first and the most important step. However, everything is even more serious, when it comes to a feature story. You need to tell about a person, a certain group or a business, so picking a subject becomes a real challenge. Some of the subjects you may know personally, which is not the best subject for a story. Even if you know who you want to write about, some founders, directors and business owners simply won’t want to talk to you. Make sure you have enough time in advance in order to choose the subject without any hurry. Schedule an interview, suitable for both of you The next stage is when you dive deeper into the assignment. You should reach the chosen subject and ask for an in-person interview. This means a meeting, not a cell phone call or a Skype conference. If you are writing about a group, you will have to talk to several members and maybe at a different time. This makes the process even more challenging. In most of the cases, feature stories are not timely, so you don’t need to rush anything and should take some time to write a good story. Let the interviews take place when it is convenient for all of the participants. The only exception is when the story took place recently and hasn’t been covered in the media. In such a case, you need to rush and be the first one to publish it. Choosing quotes Once your interview is finished, you need to sit down and reread the material, listening to recordings and pulling quotes. The quotes you choose should be relevant to the topic and represent the chosen angle. Stick to a certain side of a personality and highlight it, omitting too many unnecessary details. This is the pillar, which will support your work and will make the story honest and clear. Write a draft Now you can start working on the first sample of your work. Usually, feature stories are built around the chosen quotes. Remember, the reader wants to hear the voice of the described person and not your own thoughts on the matter. This means that you can include as many quotes, as you want. Even if half of your feature story will consist % of quotes, it will be ok. Always try to remember that the discussed subject should be placed in the center of the work, so the more details you provide, the better. Get clarification and approval before publishing When your story is finished, it is necessary to send it to the editor or professor. In addition, you can send a copy to the chosen subject if he or she requires it. However, it doesn’t mean that the subject has a right to change the story or add any details. Make it clear that you won’t grant any changes because it is unprofessional. Simply send a copy and state that you want to make sure that all of the facts and quotes are correct. For the subject, it is another chance to be introduced to the audience. Majority of writers think that it is the reason why the subject shouldn’t interfere and has a right just to notify if some of the details or facts are conveyed in a wrong way. Submit the work Once your editor, professor or the subject don’t seem to have any remarks, you can submit the story.

Homeland Security Essay Example | Topics and Well Written Essays - 3750 words

Homeland Security - Essay Example All crimes not considered capital were punishable through public torture, mutilation, or embarrassment (McCorkle 321). Flogging was common. Branding with a hot iron was frequently practiced in Britain and sometimes in the British Colonies in North America. The stocks or the pillory were used for lesser crimes (McCorkle 321-2). Numerous crimes or repeat offenses were considered capital crimes, and executions were public events. The death penalty was the final solution offered to compensate for all the other defects of the criminal justice system. The Massachusetts Assembly in 1736 issued a decree that a thief, on the first conviction, be fined or whipped. On the second, the offender would pay triple the fines and be forced to sit on the gallows platform with a noose around his (or her) neck, followed by thirty lashes at the whipping post (Miller 66). For the third offense, the culprit was taken to the gallows and publicly hanged. In his book  The London Hanged  (1992), Peter Linebaugh notes that those hanged for capital offenses in eighteenth century London were overwhelmingly from the working class, and particularly from trades experiencing the onset of craft-destroying manufacturing (Miller 42). The rise of capitalism had resulted in substantial increases in pauperism and petty thievery, which became rampant all through Europe with the decline of the feudal system. In England, steps were taken as early as 1557 to address this problem through the construction of houses of correction or workhouses, the first of which was Bridewell in London. This type of institution quickly spread throughout Britain and the Continent. Unruly apprentices, beggars, â€Å"strumpets,† vagrants, and rogues were sent to the houses of corrections, where they were manacled, flogged, and forced to carry out hard labor (Parker 105). These institutions were widely regarded as

The organizational structure of the International Brotherhood of Research Paper

The organizational structure of the International Brotherhood of Teamsters - Research Paper Example These unoins are different from other labor unions. They are designed to promote powerful labor unoins leaders. Most of the contracts are negotiated by these teamsters and they provide them with their services and therefore hold dues money. Locals hire adept labor lawyers, recognized public accountants, full-time business agents, organizers, and clerical staff. Each local elects its own officers, fabricates its structure, and votes on its bylaws, in accordance with the International Constitution and Bylaws. The next structure is the Joint council. Joint councils are established in areas where there are three or more local unions. Joint Councils help synchronize Teamsters activities. They also solve jurisdictional and legal matters.The thid structure is the Trade Division and conferences where the locals disscuss their common problems and issues and interests.The headquarter of the unoin is at Washington D.C which helps its local unoins by providing them with coordinated national nego tiations.also provide them with training and educational programs.provide them with advice and proper guidance of the experts suca as organizers, negotiators, researchers etc.
