An alien species Essay Example for Free

An alien species Essay An alien species (also known as ‘exotic or nuisance species’) is the entry of any species into the ecology of which in the past it was not a part of. This species can travel to the new ecosystem from a neighboring ecosystem or from another part of the world. An alien species can cause damage or harm to animal, plant and human life thus completely disrupting the ecosystem. Two of the alien species that have seriously affected the other inhabitants of the ecosystem in the US and the other parts of North America include the Green crab and the zebra mussel. In the home ecosystem, an alien species may not be able to thrive well due to the presence of certain factors such as diseases, presence competitors, lack of space, natural enemies, etc. However in the new ecosystem, the alien species is able to thrive uncontrollable due to the absence or restrictive factors. In the past, many alien species have been introduced into various environments. Some have entered due to human factors, whereas other may have entered due to certain natural factors. Some species may have benefited the environment, which they are entered, whereas other may have seriously destroyed the native population. Invasion by alien species can have both, economic and environmental implications. The Zebra mussel is originally from the Caspian Sea and the Green crab is from Eastern Seaboard. These are classic examples of ‘Aquatic Nuisance Species’ (ANS) (ACS, 2007, MDNR, 2006 NOAA, 2007). The Zebra mussels were identified in the Great Lakes and later spread to the other parts of North America via the major rivers and waterways. They may have spread into the US from ships that have traveled through the freshwaters of Europe. They compete for plankton in the waters and in this way seriously jeopardize the food chain. They also damage parts of boats and ships. The Green crabs had spread into the San Francisco Bay region and later through California and Oregon States. They have a strong appetite for food in their territories and in this way deprive other organisms of food. The native crabs of US have seriously suffered from the invasion of the Green crab into their home territory (ACS, 2007, MDNR, 2006 NOAA, 2007).

Have you met him - Jesus Christ? :: essays research papers

Jesus the Christ is God the Father (that One and only Holy Spirit - God is a Spirit and One) in flesh - the Son of God. It was God the Father who was responsible for overshadowing the virgin Mary and causing her to conceive. So Mary was the source of His humanity and God was the source of His divinity. He became a man but he did not cease to be God the Father of the universe. He could probably best be explained as the God-Man. Sometimes He spoke and acted as a man. Sometimes He spoke and acted as God (the Father). He came to earth to seek and save that which was lost; to minister and to give His life as a ransom - the just for the unjust. He paid the price for our sins. Then He rose from the dead three days later because He was sinless and death could not hold Him. In so doing, He showed us the way to eternal life and how we can get victory over death. He brought life and immortality to light. He offers forgiveness of sins and eternal life (with countless other benefits) to those who will come to Him on His terms seeing He is Lord of all and is the only one who can save us from death - the second death that the Bible speaks of. The grave is only a temporary place. The day is coming when all that are in the grave will hear His voice and come out of the grave to stand before God (Jesus Christ) the Judge of all the earth - a dreadful place for sinful man. We can avoid this judgment by having our sins dealt with while we are yet alive by obeying the gospel which is His plan of salvation for us. It's very important to follow the Bible formula exactly. The devil has come up with alot of variations with the attempt to make the command of God of no effect. Back when the church was born, men were convicted of their sin and asked what they should do when they realized that they had crucified their Saviour some 50 days earlier. The apostle Peter said, Repent and be baptized everyone of you in the name of Jesus Christ for the remission of sins and you shall receive the gift of the Holy Ghost.

Differences between types of economies

There are three main types of economies in the world according to the types of business they do: 1. Agriculture based economy – This is the oldest form of economies in the world. The economy by its nature has small firms and has a limited economy of scale. The economy is usually prevalent in third world countries like Vietnam 2. Industrial economy – An industrial economy is stronger than an agricultural one, due to the larger size of firms and higher society will tend to have large firms, as industry has a substantial economy of scale. Mnay of the countries started their developent stages from this type of economy 3. Service Economy – A service-based economy has its size dependent on the types of sevices it provides. This means not all industrial firms will be huge in size, and yet they cannot be considered as an economically weaker section. (Plexico n. d. ) Examples of all of these can be seen in the world, but the more advanced countries of the world are moving or have already moved from the first through the second to the third. The US was the first country to become predominantly a Service economy (Plexico n. d. ) Impact of Computers on Business â€Å"Computer science is at a stage at which it can do more for the economy, more for the way business is done†¦Ã¢â‚¬  (Gates 2004) Many people believe that the single most important change in the society in recent times has been brought about by the introduction of computers. The three types of economies which were described in the earlier section have all been significantly affected by the invention of computers. Initially Business used computers for only keeping track of accounts, money, or items that they need, but things changes at a lightning pace. It can be said that the speed, accuracy, the ability to do repetitive tasks – are the backbone of today’s research, manufacturing and production units. These characteristics also brought about the advent of the present Age of Information. The development of the World Wide Web †¦is a major breakthrough in the advancement of communication (Ayers 2007). The information age brought about the concept of global markets to the industrial and agriculture section. While the prior age concept of ‘trade’ sounds pretty close, the difference is in the nature of open-markets, which are possible only because consumers know what is there for sale practically everywhere in the world. While for service sector too the open markets mean the wider scope for selling, the services themselves can be performed at much lower rates in different parts of the world. The open markets have in turn brought up the standard of product and service quality, as now the consumers have many options available for their purchases. There are newer ways of buying and selling available to consumers, like the e-businesses, where one can practically shop or sell without leaving his home. In fact many economists believe that due to the advent of computers, the business has changed from being selling oriented – where consumers had to buy the products closely resembling their needs, to being consumer oriented – where consumer’s needs are the base for making newer products, and companies then design elaborate marketing plans to pamper the consumers so that they actually buy the particular product or service. Speculation about the future impact of Computers on Business Computers have affected the business methods so much that many people consider that area is saturated. This is however not the case, according to the point of view of many scientist and engineers. The argument given here is that, while the computers have improved a lot from the time when it was the prerogative of a few select scientists and researchers, to the present usage by hundreds of millions of people – the interface needs to be brought much closer to the common man, especially in third world countries. The first major impact would be when the computers would have perfected the art of conversation. The ability to speak to our computers is a critical part of the interface we will end up with (Ayers 2007). This would make the computers seem more ‘human’ to people. Another major improvement would be a perfect translation capability, which means people would no longer be hampered when they are interacting with a prospective buyer or seller from a different culture. Some other possible uses would be a cheaper single interface which would connect a person to his office, vehicle and home all times from any part of the world. This would mean, there would no longer be any formal office locations. This possibility is a very real one, with many people already subscribing to the this work from home or any part of the world concept, however it is still not a part of the popular culture As is seen the computers have and would still continue to impact the way business is done. The technical advances have been phenomenal and would continue to be at the same pace, bringing the world closer. However, to integrate these technologies to modify ways of business would be up to the members of the business community.

Wage And Salary Issues Union Vs. Non Union Workers

In this research paper I will be discussing how unions help all workers when it comes to salary and wages. Unions have a substantial impact on the compensation and work lives of both union and non-union workers. I found a report where current data on unions effect on wages, benefits, total compensation, pay inequality and workplace protections. But I will be focusing on two areas in this paper, and that is wage and salary issues union vs non-union workers. What is a union? A labor union is an organization that acts as an intermediary between its members and the business that employ them. The main purpose of labor unions is to give workers the power to negotiate for more favorable working conditions and other benefits through collective†¦show more content†¦With a non-union job, the employer on average, union workers are more likely to enjoy better benefits compared to non-union employees. That includes health, retirement accounts, and paid sick leave. According to the U.S. Department of Labor, 77 percent of union workers get pensions (guaranteed continued payments) after they retire from the job, compared to only 20 percent of non-union workers. Again, union representatives work out these details as a part of the collective bargaining agreement with the employer can set the wage without any formal bargaining process or input from the employee. As we look at union and non-unions I found a couple of disadvantages in being in a union that I found interesting. First one is system of abuse When they were first established, labor unions served a wonderful purpose. The working conditions in factories during the late 1800’s were horrible, and the pay was just as bad. Labor unions helped to stop this abuse of laborers. However, in today’s modern times, the labor union systems are greatly abused. People know exactly what their company can and cannot fire them for. All of the loop holes have been exposed and exploited with labor unions. The next disadvantage I found was hard workers are devalued, fair wages mean that all employees of the same level are paid the same. This is very bad for a business because some workers simply deserve higher pay than others.
