Technology And Innovations Impact On The World Essays - Development

Technology And Innovations Impact On The World In an era where human progress is soaring at a dizzying rate, society must adapt its technology to solve current world issues. In a world where the Internet, cell phones and notebook computers are becoming a necessity for everyday living, we often forget about those who still suffer attempting to meet their basic needs, including clean water, food and health care. It is time for the developed world to use their technology to help those who can not help themselves. By using these technologies there will be advances in medical services, a new economy based on the Internet, emerging information technologies and new methods for the farming and industrial sectors. More importantly, these technologies will provide the education and knowledge for these people to become prosperous nations that can fend for themselves and provide for their people. Transfers of technology from the developed world to the developing world will improve the standard of living, increase efficiency in production and become a base for economic growth, without this transfer these countries will fall further into poverty and economic ruin, with little hope for survival. For most people of the developed world, the developing world is not something they concern themselves with; they do not see it everyday and therefore it does not exist. This could not be farther from the truth. The developing world is in need of help but the developed world constantly turns a blind eye. Our current love affair with technology may provide the answer for underdeveloped nations problems. The standard of living is so low in these countries that our everyday conveniences are a struggle for the entire population to obtain. If the developed nations could meet these base needs, these countries may be able to overcome their current problems. The first issue that must be dealt with is the unsatisfactory health care and medical technology. If the developed world could send excess medical supplies along with the personnel to administer them, they might learn to take care of themselves. In time, the common diseases that kill thousands in these countries will be under control and people will start living longer, healthier lives. A second issue is the exchange of technology for agriculture and industry. As a result, new jobs will be created to provide income, while reducing child labor. As the people of these countries start to build income for themselves, the amount of crime will be reduced as people will be able to afford to meet their basic needs. As an example, instead of having to steal or beg for food or clothing, they would be able to purchase them; thus reducing crime and increase economic growth. The case study of China completed in class, showed that as people became educated and more career oriented, the size of families decreased thus reducing overpopulation. This occurs for two main reasons, people will not have time for a family and less children are required for the work force. With overpopulation and the rate of natural increase under control the standard of living in these countries will increase. With just a small jumpstart from the developi ng world, developing countries will experience a chain reaction that will increase their standard of living. This chain will start with improved medicine to increase life expectancy, followed by new jobs that will bring income and finally education that will reduce overpopulation and crime. All of these factors resulting from technological transfers will lead to an overall increase in living standard. In the corporate world of North America, it has never been easier to start a business or company. Using modern technology such and the Internet and a computer, an individual or group of individuals can become major players in today's ever increasing electronic economy. As the overall cost of doing business drops, it will make the technology more rapidly available, at a decreased cost(Freund, pg.2) and therefore level the economic playing field. As companies start cropping up, built around a new information based economy, there will be more and more demand for jobs. These jobs will give local workers a chance at making some money and providing a living for themselves and their families. With employment on the

Free Essays on Internet Freedom

Defining Our Rights Freedom of speech is a fight that has been going on for as long as the people have had the right. The Internet is just a new forum for waging this war. While people do have the right to post and say what they want, there is something to be said for protecting the youth, as well as easily impressionable minds. At this time the Internet is an ideal medium for the population to express what it wants at any time. This however may change soon, as international governments are discussing legislation and implementing censorship for the Internet. I think that we as a people need to address this issue now and fight to keep a right that has been a foundation for our culture. If we do nothing now, then laws will get passed that may very well infringe upon our right to freedom. Everybody is essentially for free speech. The issue is the limits and boundaries to that speech, and how we should enforce them. There are two sides to this issue and they make it extremely hard to distinguish right action from wrong. On one side you have parents protecting their kids from obscene material, and government protecting its people from terrorism. On the other side are groups and agencies fighting for every last ounce of free speech. Trying to empower the people by keeping them overly and completely informed. Both of these groups are entitled to the feelings they have and neither one of them are in the wrong. So the goal is to create legislation and law that conforms to all walks of life, and is non-bias towards any of our people. Freedom of expression has already faced tremendous judicial attention, and now that the Internet is involved there are even more difficulties to deal with. At this time attempts are being made to control two aspects of expression. Thes e aspects are obscene material such as pornography, and compelling government interest such as instructions on how to make a bomb. The Communication Decency Act is o...

Chemical Imbalance and Depression

However, chemical imbalance doesn’t lead to every kind of depression seen in the lives of many people. Admin,2012) Approximately five percent of the United States’ population experiences a depressive episode that requires psychopharmacological treatment; in any one year, ten to twelve million Americans are affected by depression, with the condition twice as common in females than in males. (Ho, 2002) We all have chemical signals that are called neurotransmitters and they come in a variety of forms like Serotonin, Dopamine, and Norepinephrine. All three of these neurotransmitters play a very important role in maintaining normal mood, motivation and concentration. What is Serotonin? Serotonin acts as a neurotransmitter, a type of chemical that helps relay signals from one area of the brain to another. (Bouchez, 2007) In depressed brains, the Serotonin signal had been somehow weakened because of a chemical imbalance in the neurotransmitters. (Mukherjee, 2012) Low Serotonin levels are often attributed to anxiety, depression, panic attacks, insomnia, obesity, eating disorders, migraines, and alcohol abuse. (Integrative Psychiatry, 2012)Treatment for increasing levels of Serotonin in the brain are medication like Prozac, Zoloft, and Paxil. These medications are known to work by making more serotonin in the brain. (Carver, 2002) If we have too much Serotonin you will have this feeling of bliss and it can also produce a life threatening condition known as Serotonin Syndrome. To date there have been no recorded or documented studies proving that the brain levels of Serotonin or any neurotransmitter are in short supply when depression or any mental illness develops. (Bouchez, 2007) Serotonin can be measured in the blood but they are not sure that blood levels effect the brain’s level of Serotonin. The next neurotransmitter that is part of the brain is Dopamine. What is Dopamine? Dopamine is in the area of the brain that is considered to be the neurotransmitter of focus and attention. Dopamine relays impulses across the microscopic spaces, called synapses, which exist between adjacent nerves, thus allowing the propagation of messages from one nerve to the next. (Christensen, 2011) Low levels of Dopamine make concentration and focus very difficult, this is associated with Attention- Deficit- Hyperactivity- Disorder. Carver, 2002) If patients are found to have low levels of Dopamine, you will be prescribed medication that actually slows down the hyperactive by increasing Dopamine boasting the level into normal range allowing them to focus and pay attention. Researchers say that if a patient is found to have prolonged exposure to Dopamine, patients are more apt to  abuse drugs. Most addictive drugs, such as cocaine and  amphetamines, directly or indirectly raise dopamine level s, and the chemical plays a major role in drug-induced highs. WebMD, 2005) The next neurotransmitter that is part of the brain is Norepinphrine. What is Norepinphrine? Norepinephrine is the neurotransmitter often associated with the flight or fight response to stress. Norepinephrine also functions hormones in the body. Low levels of Norepinephrine are associated with a loss of alertness, poor memory, and depression. (Carver, 2002) It has been found that low levels of norepinephrine are in ADHD and depression patients. If the levels are two high patients may feel fatigue, have muscle cramps and a sense of being on edge. Almost all anxiety disorders involve norepinephrine elevations. (Carver, 2002) Psychiatrists would treat low levels of norepinephrine with newer antidepressants like Effexor and Serzone. Treatment of high levels of norepinephrine the psychologist would prescribe GABA, also known as Gamma-Aminobutyric Acid. Summary and Conclusion As I stated in my debate it is very clear that depression is one of the possible symptoms of chemical imbalance. However, chemical imbalance doesn’t lead to every kind of depression seen in the lives of many people. Admin, 2012) Not all medication has the same dosage. There are many different types of medication that you can have prescribed if your brain is low or has high neurotransmitters such as Serotonin, Dopamine, and Norepinephrine. If you feel like you are depressed go and see a Psychologist, so the correct medication can be prescribed to you. References Admin (2012). Is  depression  caused by chemical imbalance in the brain?

Critically assess the attractions of commodities as an asset class Essay

Critically assess the attractions of commodities as an asset class over the short and long-term - Essay Example The ever-expanding list now also includes products such as financial instruments and stock indexes that trade on a commodity exchange. Commodities can be considered to be an asset class in their own right and long-term investments in the same have resulted in equity-like returns to investors. An investment can generally be considered a separate asset class when its returns are independent of other asset classes; its returns are both positive and significantly different from cash; its return cannot be replicated with a combination of other asset classes. Commodities have all these characteristics and therefore provide considerable investment portfolio diversification opportunities. It provides return and risk opportunities beyond that of simple inflation hedging and has sources of risk and return that are significantly different from and independent of traditional assets such as stocks and bonds. Moreover, its advantage lies primarily in that its risk and return trade-offs cannot be easily replicated through other investment alternatives. Thus commodity investment has enormous growth potential and poses some unique attraction for investors who understand its unique characteristics, benefits and challenges. For instance, commodities generally outperform other asset classes in an expansionary phase and deliver extra-ordinary returns within short periods. Like property, commodities offer low to negative correlation with equities and bonds and fixed income instruments and, therefore, provide a natural balancing and sobering effect on the portfolio. A correlation coefficient is a number between -1 and 1 that measures the degree to which two variables are linearly related. A positive correlative coefficient means that the two variables are directly related, i.e. the value of one will increase or decrease along with the increase or decrease in the other. A negative correlation means that the variables are inversely related and when one

Risk Management Essay -- Business Management

Risk is a commonly used term and its usually liked with bad impacts on our objectives. The Oxford English Dictionary define risk as â€Å" a chance or possibility of danger, loss, injury or other adverse consequences†. There is no agreeable technical definition of risk as it went through many developments. The first stage was the management of threats only then the term is extended to cover the threats and the opportunities which face the organisations. The latest stage which is the management of the threats, opportunities, uncertainties and its sources. Of uncertainty (Ward and Chapmen, 2003). Therefore, Dowie argues to banned use the term â€Å"risk† in the risk management because of its misleading. The definition will be used in this paper is the Australia/New Zealand standard definition which is "The chance of something happening that will have an impact on objectives" (Australia/New Zealand Standard, 1999). The reasons of using this definition are the simplicities and the coverage of the negative and positive effects on objectives. Risk management has been done for thousands of years (Bernstein, 1996). The Risk management term was first introduced in the 1950s by the insurance industry. The first text book published about risk management in 1963 titled Risk management and the Business Enterprise by Robert I. Mehr and Bob Hedges (D’Arcy and Brogan, 2001).

Macbeth: Differences Between the Play and Movie

The play MacBeth, by William Shakespeare, which we read and the movie, by Rupert Goold’s, which we watch has several diffrences but all put out the same message. The main diffrences in between the play and the movie is the portrayal and functions of the witches, the changes of the setting and some key scenes, and the diffrences of the functions of the main characters and also the minor characters. The portrayal and function of the witches in the original play of MacBeth and the movie have several diffrences. In the play the witches are discribed as ugly things with beards and are outcasts of society that wear black robes. But in the movie the witches are very creepy. They have a more modern day horror film look. The witches are no showed as witches but as nurses with masks and black framed glasses. Not only are they shown as nurses (witches) but they are kitchen staff, serving women and cleaning maids too. Also throughout the movie the witches are roaming around in the background of pretty much every scene. It gives a feeling that they are there constantly to ensure the MacBeth and his wife, Lady MacBeth, fulfill their tasks that needed to be done. There are several diffrences between the play and the movie but the main diffrence is the setting of the two. In the movie by Rupert Goold the setting of the ‘’play’’ is in the 1900’s when World War II was taking place. MacBeth and all the other characters are in a Nazi-based area. Where as in the play originally created by William Shakespeare, it is taken place in the olden days, way long ago where it is taken place in a castle with kings and such. Another great diffrence inbetween the two are the weapons used. In the riginal play the main weapons are swords and sheilds and daggers and so on, where as in Goold’s movie the weapons are semi-automatic machine guns, bombs and more new-age weapons. A major scene diffrence in the movie from the play is when the 3 murderers go out to kill Banquo and his son. Instead of Banquo and his son on a horse strolling, they are in a train cabin. In the play the three murderers are Caithness, Angus and MacBeth where as in the play thew three murderers are Caithness, Angus and Lennox instead of MacBeth.

Viewpoints of the Great Carajas Project

The main two types of people involved in the Great Carajas Project are the CVRD ( A company which owned mines) and the Garimperos. Garimperos are the illegal miners or free lance miners. They mine for gold and are forbidden to mine in the Carajas area. The Garimperos come from all over Brazil and usually mine for Gold. They are annoyed with the government because they feel that they have the right to mine in the area as well. If a Garimpero is caught mining where they shouldn't be, security guards will hunt them down and confiscate their gold. In Serra Pelada 80,000 Garimperos invaded a Gold mine and took it over. They were extracting around $200 million annually but although they were making good money, they are damaging the environment and working in a very unsafe manor. They are using mercury to separate the gold and this mercury was then getting into rivers and contaminating/poisoning them and various food chains. They also burn the mercury which gave off toxic gas and the safety in the mining pits was appalling; there were regular rock falls and some miners are killed. In January 1986, Riot police were ordered into the mines to force the Garimperos out. A miner was killed by accident when a policeman intended to shoot a bullet in the air but shot too soon and killed the miner. Soon after, the mine was shut down but the company re-opened it and increased safety levels by using bulldozers. The CVRD were confident that they would make lots of money and they were very strict about the area; check posts were set up to ensure that only people involved with the mines/CVRD were allowed to enter and all cars were searched, only allowing people to enter who had a permit. The government were in control of the project and showed interest because of the investment being made. The project had an annual income of $700 million. The company are licensed to run the project, unlike the Garimperos. The companies are looked upon as being sufficient but inhumane and the Garimperos are seen as trying to fend for themselves but obliviously harming the environment and putting their own lives in danger. Local tribes who live in the forest called Amerindians are moved out of their settlements so that the CVRD can expand the mining areas. The CVRD destroy their living area and when the Amerindians next settle they are still weary of having to move again. In My opinion I think that both Garimperos and the CVRD should be allowed to mine there. They should compromise as to who gets what land so that everyone is happy. I think that if this did happen the Government would have to do some serious thinking into safety regulations and the damaging of the environment.

CLK-1 Mutants and Aging essays

CLK-1 Mutants and Aging essays CLK-1 MUTANTS AND THEIR ROLE IN AGING Aging is a fact of life, it can be scary to watch yourself and those around you grow old. The idea of a mythical fountain of youth has enticed adventures from around the world for centuries. The idea has enchanted me since I had a conversation with my grandmother in which she stressed that the only thing that mattered in life at her age was health. So what causes the body to wither with age and is there anything that we can do to prolong the inevitable? There are many different causes of aging, all of which result in a decline in the bodies ability to function properly. Recent research has come up with several different ways to combat some of the major causes of the physical degeneration that is associated with growing old. Studies of long-lived mutant worms, yeast, and mice are useful tools in examining the processes that are involved in limiting/expanding the life span of organisms. Some of the most intriguing gene mutations known to increase life span are the daf-2, clk-1, and isp-1 which deal with the regulation and control of Reactive Oxygen Species (ROS). ROSs consist of molecules such as superoxide, hydrogen peroxide, and hydroxyl radicals, which cause extensive damage to biological macromolecules. This leads not only to many serious diseases, but also plays an important role in aging. The main source of ROS is in the mitochondria, where superoxide is produced during the process of electron transport and can give rise to other reactive species through reactions with detoxifying enzymes (1). More specifically is the production of ROS involved in processes dealing with the reduction and subsequent oxidation of the redox-active lipid Ubiquinone (UQ). Understanding the role that UQ plays in the Electron Transport Chain (ETC) helps to understand the complexity of ROS formation. The ETC consists of fou ...

Due to the extensive number of variables needed to be considered there is also the problem of lack of baseline data that can be used for comparative analysis of studies undertaken. There are different factors covered in the study such as the causes of developmental disabilities, challenges in the research process, clinical study of toxic elements known to affect the neurodevelopment such as lead, mercury, manganese, polychlorinated biphenyls, flame retardants, pesticides, nicotine, and alcohol and other solvents. Upon analysis of the article by Schettler, it can be considered that the study is more of a library based research since the data are presented on a textual manner. It can be considered qualitative in nature based on the same reason that the topics discussed are presented in paragraph form and there are no tabulated data. According to the determination of the source of the article, it had been known that it is a derivation from another article written by the author, thus, compared to the reference article, this one can be considered as an abridged or shorter form. On a reader’s perspective, the article was able to present a general point regarding the importance of an in depth study on the factors affecting the different types of neurological disabilities but if one is interested in an in depth determination of the factors and their specific mechanisms, it is important to have a more quantitative presentation of the data. In relation to the fact that the article is based on a nother article, the data presented cannot be considered as first hand although it is written by the same author. The fact that the data in this article is only based on the article which discussed the toxic threats in child development,

Compair the Matrix, Cathedral, and Billy Slaughterhouse 5 to the one Essay

Compair the Matrix, Cathedral, and Billy Slaughterhouse 5 to the one who ascends from in The Allegory of the Cave - Essay Example On the hand, the blind man’s view of life comes from an open perspective and he is ready to learn new things about life (Carver, 2002). The narrators view on blindness (life), changes when the blind man asks him to describe the cathedral for him. When he lacks words to do this, he is forced to show him by drawing, by catching his hand. Communication through symbolism helps him to understand the world through the blind man’s point of view. The blindness that separated them at the beginning brings them together. This is achieved through seeing the world from others perspective. Slaughter house- five basically explores the illogical nature of human beings, free will and fate. This book explores the concept that we are powerless and can do only what we can actually do. Billy Pilgrim is an anti-war character, who trains as a chaplain assistant, earning him disgust from his friends. Despite being the main character of the book, he gets on the nerves of everyone because of his dreams, weak body and fecklessness. He still manages to survive one of the main human atrocities, where others have failed. Nothing in Billy’s life happens out of his own will, but he watches as his life unfolds in front of him for example he is recruited to the war without his consent and gets married to a woman he does not love. In most of the novel, his character is not one the narrator could call a â€Å"character†, and only does so when he becomes â€Å"crazy† and breaks out of hospital to a radio talk show to tell about â€Å"Tralfamadore†. This is a place where he was abducted to by aliens, and this could either be in his head or reality. Events in this place take place simultaneously, so nothing happens before or after the other. In this situation, a person can choose only the good memories of life. Some can argue that the events in his life are due to the post traumatic disorder he has suffered in his life. We all can agree that human life invol ves suffering, and in his case, this seemed to be happening a lot. The old ways of explaining this suffering; religion and patriotism, do not seem to work. In the end, Billy awaits death without fear and is in control, something he was not able to do throughout his life. He ends up being the most unlikely war heroes. In Matrix the movie, Thomas Anderson, is one of the many billions of people connected to the Matrix unaware that they live in a virtual world. Despite being a respectable programmer for a software company, he is also a hacker with an alias†Neo†. This is when he gets to know about the Matrix. He has a choice to forget all about it and live his normal life, or gather information on the Matrix. Neo chooses to liberate humanity from the virtual fate, and there begins his journey to enlighten and being a hero. This is despite warnings from those who know the truth. He embraces his role and even learns fighting skills quite first, in the journey of being savior of the universe, where he gets his other name, â€Å"the one†. This is when we start to see his messianic like qualities and belief from other characters such as Morpheus and the Oracle, towards human liberation. There are several similarities between this character and Jesus Christ, for example Jesus was both earthly and godly, which can be compared to Neo’s ability to go through realms. The name Thomas can also be compared to doubting Thomas in the New Testament, who doubted the resurrection of Christ. Similarly, Neo doubted his abilities at
