The Contribution of Informatics to the Development of Social

Essay The contribution of Informatics to the development of social networks and their impact on society Change is continuous constant; inevitable and sometimes unpredictable. We can easily say that world has changed a lot in industrial and mechanical era but the change seen in last half a century is exponential and amazing. If we have to credit one invention which had bought such a revolution, it would be computers. With advent of computers, a new paradigm shift was seen, computers enable mankind to compute and process data in more meaningful way with a blink of an eye.And it did not stop there, once a standalone computing machine, the true acumen of computers was judge when they were connected with each other forming a giant mesh of information following from one place to another in speed of light. As technology advances, the hardware and software capabilities of computers increased, now recently 1terabyte of hard disk space is normal for personal PCs, where servers and super comput ers can manage thousands of terabyte easily.Well it is debatable that can we apply â€Å"Moore’s Law† on the expansion of Internet too, but in practice it’s seen that Internet has grown tremendously in past years. Currently there are more than 50 billion web pages on Google alone, so one can easily imagine the depth and breadth of Internet. Humans have always shown eagerness and urge to learn unlearnt, find which is not found yet and invent things with improvisation and innovation. This hunger for knowledge is reflected on Internet, as it has abundance of information where millions of people quench their thirst.But the most amazing thing about the age of information and Internet is that they not only infested our professional or educational life but they have imbued our social life too. Aristotle once quoted in his Politics that â€Å"Man is by nature a social animal’, well if Aristotle would have been alive now he would have uttered that indeed man is s ocial network animal. Internet helped to shape new social norms in our generation, though we are in transaction period but in more than two decades this would be a tautology.Alvin Toffler in his book â€Å"The Third Wave† declared that the shores of the Earth have been struck by wave of information. Interestingly the power of Internet and socializing through networks was so strong that when Alvin Toffler wrote this book back in 1980’s Internet had not yet reached its epitome, though it has not reached it now but it’s far more glorious than back in 80’s. But still the anthropological changes pointed by Alvin are very visible and evident. Ships, trains, supersonic jets etc. have not shortened the edges of this world but Internet has really made this world a global village.It would not be an exaggeration; but single invention of making a meager data packet flow from one point to another brought all other inventions of 20 century to their knees. As there was a huge junk of scattered information lying on the Internet which would be useless in majority of cases was channelized by the brilliant idea of socializing sites. The informatics provided a concrete edifice to these social sites which developed their existence surrounding it. I can still remember that when I made my first account on orkut and shared a funny and witty scrap among my friends. I was rejuvenated by the replies and then it was no looking back.The concept of interacting with your friends who are at far geographical locations was just amazing and it also provided a taste of cross cultural exchange, and not only that but also increases your intellect by indulging in talks and debates around the world. The lacuna of geographical, cultural, religious, cast, creed etc. was beautifully filled by social sites and networks. The vastness of these social sites are unimaginable, as on face-book statistics, its reported that 800 million users are active member of face-book, and accor ding to Metcalfe’s law the number of connections can be calculated by squaring the connected people.One can hardly imagine vastness of the â€Å"node link† graph of these social sites. There is no harm in accepting that these social sites are now imperative part of our lives. But with pros there are also some cons attached they come with package, as human being is a bit stubborn, prejudice and many people will argue but sometimes irrational too, social site failed to provide tolerance and flexibility.It rather serves the purpose of fulfilling your social desires; desire to be loved and liked by your friends etc. But still I am not pessimistic, I am firm believer that these social networking may not bring complete ignorance and patience but will pave the path for global tranquility. In the end, I would like to conclude that social networking has shaped this world and I feel lucky and blessed to be a part of this revolution.

Hate Crimes: Matthew Shepard Essay

Wyoming, October 7th 1998. Aaron Kriefels is cycling in a remote rural area when he sees what at first he believes to be a scarecrow tied to a fence. He looks closer and sees not a scarecrow, but a young man badly beaten and close to death. The victims name was Matthew Shepard. On Dec. 1st 1976, Matthew Shepard was born in Casper, Wyoming. He attended elementary school in the states, but after his first year in high school his family moved to Saudi Arabia. He then attended the American School in Switzerland where he was elected as a peer mediator. His friends and peers felt comfortable talking to him and he was someone you came to when you needed advice. He was described by his father as â€Å"an optimistic and accepting young man who had a special gift of relating to almost everyone. He was the type of person who was very approachable and always looked to new challenges. Matthew had a great passion for equality and always stood up for the acceptance of people’s differences. â€Å"[1] In February 1995, during a high school trip to Morocco, Matthew was beaten, robbed, and raped, causing him to withdraw from school. According to his mother, from then on he was prone to experiencing panic attacks and depression. Although this time in his life was extremely difficult, Shepard still graduated in May then attended Catawba College in North Carolina and Casper College in Wyoming, before settling in Denver. Shepard became a first-year political science major at the University of Wyoming in Laramie, and was chosen as the student representative for the Wyoming Environmental Council. Shortly after midnight, on October 7th, 1998 Shepard met two men (Aaron McKinney and Russell Henderson) at the Fireside Lounge. He was offered a ride home, but shortly after leaving they robbed, pistol-whipped and tortured him, tying him to a fence leaving him to die. Matthew was left in the freezing cold suffering from his injuries before slipping into a coma. In total, it took 18 hours before he was found and rushed to the hospital. Upon arrival it became apparent that his injuries were too severe and the doctors couldn’t operate. On October 12th, Matthew Shepard died of his injuries, never having woken up from his coma. During the trial, McKinney tried to justify his actions by originally pleading that he and Henderson were driven to temporary insanity by alleged sexual advances by Shepard. I believe this is one of the key factors in understanding why people do what they do when it comes to homosexually based hate crimes. When men ‘check out’ or ‘hit on’ women they believe it is there right. The right to gaze upon a woman’s body is something they genuinely believe is a man’s right. There is no female equivalent to a man’s gaze. It is something that is seen as powerful and socially intimidating, and when the two men in the bar noticed Shepard looking at them it made them believe they were being hit on as if they were women. Both Aaron McKinney and Russell Henderson felt they needed to defend not only their masculinity but their heterosexuality. This is very important because, later on in the trial when McKinney states that while in the car Matthew made an apparent sexual advance toward him, instead of backing away McKinney begins hitting Shepard. After feeling like he had been emasculated back at the bar, I bet he was just looking for an excuse to exert power over Matt. Whether he had in fact made sexual advances toward Aaron isn’t the point, the point is that McKinney chose to defend his heterosexuality by literally beating the life out of him and showing him that he had the power. Both McKinney and Henderson were of slight build, but with Matthew being even smaller and only reaching 5’1 it only solidified in the minds of the two men their power of the homosexual man. What happens next is what changed this from a triggered â€Å"Gay Panic Defense† (which is, in my opinion a completely bogus and ridiculous excuse for those who can’t control their fists) to a hate crime and a murder. After severely beating Shepard in the moving truck, Henderson tied him to the fence. Their decision to tie his body up for everyone to see is part of their intensions to make it a public display of what they believe should be private. In an interview for the Laramie Project (a play based on the events of Matthew’s death), McKinney’s girlfriend tells writers about why the two men really decided to invite Matt into their car. After being disgusted at the thought of being hit on by a gay man they go to the bathroom where they plan to put on a gay pretense in order to lead Shepard into their vehicle and rob him. They wanted him to be punished for â€Å"coming onto straight people. † By lifting his body in midair and tethering him to the fence they were aware that someone would find him that way. They didn’t hide or trash or burry the body, they made it a spectacle. But in doing this, you can deduce that this murder wasn’t fully about Matthew Shepard. He was a trigger, he was someone they could take advantage of. They used his body to show not only to Matthew himself, but to Laramie and the surrounding community that they were defending their ‘manhood. ’ And in one of the most brutal ways you can imagine. Hate crimes towards people who are a different sexual orientation then others are more common than people think. There are a lot of organizations that try to help stop these hate crimes but I think that these situations should be in the news more often. People need to be more aware about what they say and what they do because you never know who could be listening. It could be your children who will take what you say as the truth. It could be someone walking near you or even in the same room and be deeply offended by what you say. You never know who you could offend, be it a friend, a co-worker or even a family member. People need to watch what they say because you never know who will be listening. Hate crimes must be stopped and it will take people to take action against it in order to make the world a better place.

The Epistle to Philippians Essay Example | Topics and Well Written Essays - 750 words

The Epistle to Philippians - Essay Example First of all, it would be advantageous to see if there are lots of similarities between the above mentioned versions. One might argue that there are many parts of the text that are similar word for word: the very beginning, some parts in the end and many others. However, its interesting to note that there are two words, namely â€Å"true† and â€Å"pure†, that coincide in the list of what a Christian should think about, while others are not similar at all. Indeed, there are more differences in the two texts than similarities. For example, NIV says that Paul â€Å"pleads† two women to keep their faith strong, while NRSV uses the word â€Å"urges†. It is clear that the latter verb has far stronger meaning. Another difference is seen in the words that are used to modify the word â€Å"companion†: NIV’s â€Å"true† versus NRSV’s â€Å"loyal†. One would make no mistake arguing that the former word has some important connotatio ns. The next suitable example is the difference between the phrases â€Å"do not be anxious† (NIV) and â€Å"do not worry† (NRSV). From a psychological point of these two states of mind are different. Now it would be important to perform some exegetical analysis. In the very beginning, Paul greets the congregation warmly. Then he encourages them to stand firmly in their faith in Jesus Christ. Afterwards, he calls two names of the women who need extra support since they might be falling from grace; that is why the believers should unite together. The next statement urges the Christians to rejoice in God all the time. The Apostle says that God is near. That is why the believers should not worry about anything and pray to God all the time, presenting Him with their concerns. In this case the peace of God will come to them. In the end, Paul lists what Christians should think about: these are universally accepted positive values. Finally, he urges all the believers to put into practice their knowledge and enjoy their faith.  The passage from this book is related to the New Testament in that sense that it reflects the spreading of Christian Church and tries to reinforce the newly fou nd faith. It is also related to the Old Testament in that aspect that people should base their life firmly on their faith in God.

Israel 2 Essay Example | Topics and Well Written Essays - 500 words

Israel 2 - Essay Example â€Å"In contrast to these sources which presuppose that the Omrides were strong rulers over an autonomous kingdom and in hostile relations with the Yahwistic prophets, the stories of the three battles with Ben-haded and the Elisha stories presuppose quite a different situation. Both of these narrative groups†¦depict the king or kings of Israel as international weaklings, bullied by the Syrian kings of Samaria.† (Miller and Hayes, 262) Therefore, as pointed out by Miller and Hayes, the sources relating to the Omride kings disagree over the political power of the Omrides. Similarly, the authors argue that there are significant conflicts in the sources relating to the Omride kings as the sources disagree over the sequence of Syrian kings during the period of the Omrides. The information about the sequence of Syrian kings during the period of the Omrides conflicts â€Å"with the biblical stories of the three battles with Ben-haded as well as with the Elisha stories, if one assumes that these two narrative groups are in proper context. That is, if the stories of the three battles with Ben-haded actually pertain to the last years of Ahab and the Elisha stories actually pertain to Jehoram’s reign, then we have a Ben-haded on the throne of Syria followed by Hazel rather than a Hadadezer followed by Hazel.† (Miller and Hayes, 263) Miller and Hayes provide an important picture of Omri and Ahab in international politics/affairs in the famous book A History of Ancient Israel and Judah and they give convincing evidences to establish and support their picture. According to the authors, Israel reached the zenith of its glory during the rule of Omri and Ahab. The readers are not able to gather a great picture about Omri from the documents, although he is the earliest biblical characters to be mentioned in ancient non-biblical documents and also the first king

Discuss the implications of globalisation for both rich and poor Essay

Discuss the implications of globalisation for both rich and poor countries - Essay Example United Nation Development Program (UNDP) is concerned that inequalities and poverty level have increased in poor countries. UNDP indicates the major cause is global trade and finance system (World Bank, 2000). Another implication of globalization for the rich and the poor countries is that there is increased global protest and chaos. For instance, global trade means that investors from different countries have access to rich or poor countries thus increasing the chances of insecurity and drug trafficking. Security is important to poor and rich countries. While most countries join together to improve trade, in some cases insecurity is experienced. Likewise, illegal transactions have been reported for example importing of guns and elephant trunks which is mostly done by the residents of the countries (David, 2001). Drug trafficking like cocaine among other hard drugs is a threat to the countries residents especially to the youths since in most cases the drugs are sold to the youths thu s making a country lowers the economic status. This is based on the fact that young people support a country with the required output in the factories and in plantations among other areas. The rules and ideologies of globalization are that free trade is allowed, deregulation, privatization and structural adjustment which has left the poor countries residents to be homeless, landless and hungry. Since investors from other countries look for cheap labor, no training when recruiting new resources making the matter worse in poor countries. This means that access to health facilities, education, water, sanitation among other things is not easy thus resulting to negative effects on the productivity in such countries (Pritchett, 1998). On the other hand, the rich countries are not affected but rather they keep on increasing their wealth. For example, from 1986 to 2000, the total US wealth that was controlled by people increased from $7.2 trillion to $27 trillion. This

Denver's Halloween riot( Colorado History the centennial state ) Essay

Denver's Halloween riot( Colorado History the centennial state ) - Essay Example The Chinese first settled in Colorado during the 1860s; they were drawn there by the completion of the transcontinental railroad and demand for cheap labor (Hall 77). They existed amidst poverty, wretched living conditions, and persecution, and they mostly worked in mines, laundries, and as house servants. By 1880, hostilities between other immigrants and the Chinese had intensified as competition between them for jobs increased and opium dens habited by the Chinese getting negative publicity from the local press (Brown 178). The Chinese were accused of invading the state and therefore forcing women into prostitution and men into starvation. There were accusations that California had already been ruined by Chinese labor and that Colorado was then threatened with similar disaster (Historical Findings 18). One week after the Rocky Mountain News reported about the looming disaster in Colorado due to Chinese invasion, Halloween riot erupted in Denver. The riot began when a group of four drunken white men attacked Chinese men who were playing pool along Wazee Street at John Asmussen’s salon (Brown 179). Soon after, a crowd of about three thousand started throwing bricks and breaking into the homes and stores of the Chinese. Attempts by the police to calm the riot were futile as they were vastly outnumbered by the crowd and were not able to stop the growing violence. As a result of the riot, Chinese homes and business in the area were gutted (Hall 85). Denver’s Halloween riot is important in history of Colorado; even though the riot did not immediately end the struggles with underlying issues of racism, it helped to address the challenge of racial prejudice in the long run (Brown 180). Since then Colorado has grew to be among the top states for business. In 2010, it was rank ed as the third top state for business falling behind Texas and Virginia. The state has been able to overcome the challenge of

Philosophy of social work Essay Example | Topics and Well Written Essays - 2750 words

Philosophy of social work - Essay Example I have not only answered these questions, I feel that I have elaborated on them and asked further questions to the principal answers, in order to explore them on deeper levels. I feel that the resulting answer reflects not a simple, pre-determined response to the question; it rather reflects a step by step response to the question – a response I did not know I would provide until I had assessed and recorded it. In relation to philosophical concepts, a single, predetermined answer is not possible, or rather lacking as a response. Rather, my staged self-exploration provides a deeper understanding of my philosophical approach to social work. Before I attempt to define my own personal philosophy of social work, I feel that a more ample beginning is required; a much more basic start from which I can build the foundations of my personal philosophy. I feel that I must define the term ‘social work’; what it means to me, how I interpret it and adopt it in my work. For to do this is to have constructed a basis when properly answering the question ‘what is my philosophy of social work?’ To explore the personal definition of the very concept I seek to explain my philosophical outlook upon, I explore the methods and basic contexts within which I try to define the term. I bring everything together neatly, which was once jumbled and unexplored until now. So, the beginning: what is social work to me? How do I define it and with what frame of mind? To help others, to bring those in need to an equal level with others, to achieve and maintain justice, to keep a constant compassionate and optimistic outlook, to ensure liberty, to restore and assign rights. This is social work....to me. And when further trying to define these terms and meanings, I find that I am further developing and utilising my philosophical outlook, and discovering how I approach these definitive tasks. It appears to be more than a simple answering of the question; it is more

Compare how death is presented in three poems in the Anthology Essay Example for Free

Compare how death is presented in three poems in the Anthology Essay The three poems Remember by Christina Rossetti, Plena Timoris by Thomas Hardy and Refugee Mother and Child by Chinua Achebe all portray death in different ways. Rossetti explores the acceptance of death, whereas, in Refugee Mother and Child we see the unwavering love the mother has for the child. In the poem Plena Timoris the persona recalls how love can be so extreme that could lead to despair and death. What I found intriguing about these poems was how love could be both a dangerous and positive force towards the subject of death. Love could drive a person to their grave but also love could be the will for a person to stay strong and never giving up. Christina Rossetti a devote Anglican to whom church and family were paramount. It is known that two marriage proposals which did not live up to her religious fervour therefore she turned them down. Because of her religion Rossetti appears to have been obsessed with her own pending death in this poem. Her belief was that death was the ultimate goal for everyone, and because of such she very much planned her own pending death. The structure of this poem was in a Pertrachan Italian sonnet form. In this form poems are meant to be very structured and are need of following a strict rhyme scheme. However there was a change in rhyme scheme between the octet and sestet. In the octet the phrase â€Å"Remember me† was mentioned three times, but a sudden change was then noticed, as in the sestet â€Å"Forget me† was repeated twice. This change is used to suggest the possibility of forgetting and being happy rather having instructions to remember. This could show even before her death she was still doubtful between secular love and materialistic love. Chinua Achebe is a proud Nigerian who observed the civil war in his country and horrific suffering of the innocent refugees. In Refugee Mother and Child he relates the sadness of death between a child and a mother by writing in free verse. The line length of the whole entire poem was three lines. In the first stanza there is only one sentence, and in the last stanza two sentences were present. These long sentence increases the intensity on the images and also the enjambment suggests the suffering of these innocent refugees. Plena Timoris is set within the conservative morality of Victorian England where women had a subordinate and dependent position in a male patriarchal world. Hardy uses different tones throughout the poem to evoke how he thinks about love. He sees love in a very cynical view and is making an effort in portraying love is not everlasting but tragic and indecisive. In the first stanza the use of alliteration in â€Å"the lovers looked over† emphasizes love was lyrical and a harmony of life by the â€Å"l† sound produced. But in the second stanza onwards there was a sudden transition and the change of tone was turned emotionless and insensitive. From the phrase, â€Å"There’s a woman in the canal below† there is a sense of bluntness and matter of fact to it. This sudden contrast of tones between the stanzas just enforces how Hardy thinks about love. The rhyme scheme of this poem does not change, the structure is: â€Å"abbab, cddcd†. It is in a strict and orderly fashioned. This rhyme scheme reflects how Hardy feels abut love and death. That love would have happy times but at the end it will just lead to despair. Also by having such a strict rhyme scheme it also suggest how Hardy views women opinion in love. As this structure is so old fashioned it provides a kind of security and how the future is being set. This may be very well how women in the male patriarchal world viewed love therefore he viewed love in such a cynical way. In the poem Remember, Rossetti portrays death as an eternal and a beautiful thing, instead of fearing death like the other two poems. The persona appears to have been planning and waiting for her own pending death. Rossetti uses strong imagery to reveal about how she feels about death. The opening two lines of this sonnet â€Å"Remember me when I am gone away, Gone far away into the silent land† gives an idea of how she hints that she is dying. The phrase â€Å"silent land† could be translated as a cemetery or individual grave. It can also be seen as a metaphor as the phrase also suggests calm after life. All these techniques used by Rossetti could be seen that she is using euphemism to make death sound less harsh, and instead it is a goal that should be achieved by everyone. Whereas in the poem Refugee Mother and Child, Achebe reflects the sadness of death by creating a tragic atmosphere. This poem does so by introducing shocking images and strong words. In this poem it is full of pathos; it is a very emotional poem. The alliteration used in: â€Å"struggling in labored steps behind blown empty bellies† evokes a sense of harshness, as the â€Å"b† sound which is constantly repeated makes a very plosive sound. The juxtaposition used in â€Å"the rust – colored hair left on his skull† emphasizes how horrific death is towards the child. Not only is this phrase very descriptive but it also seems to describe the layers of death. It is very photo journalistic which makes the atmosphere very tragic and grave. In Plena Timoris death is conveyed in the strong imagery created by Hardy. The negative imagery in â€Å"And her arm dropt† symbolizes how because the woman in the poem sees love could lead to death it is in fear of it, therefore there is a loss of affection towards the man. The alliteration in â€Å"dim dreads† and â€Å"slowly sees† portrays a sense of insecurity coming from the woman. As she slowly sees how extreme love could lead the despair and death. Lastly, the phrase â€Å"till an arm upbore† in stanza two is a horrifying image. The word upbore gives a sense of death and the whole phrase conveys a sense of fear towards the subject death as it is being described as horror and terror. In Remember the poem creates a huge impact on readers. It is a poem which is very memorable. This is because Rossetti describes death in a very different way than most poets therefore standing out from the other poems. The repetition in this poem emphasizes the point of her point of view and the confusion between her religion and materialistic love. The phrases â€Å"Remember me† and â€Å"Forget me† was repeated a number of times and because of such it plays a great role in the poem. As it gives an impression on how Rossetti is judging between her church and her religious fervor. The strong descriptive imagery in the poem Refugee Mother and Child and the choices of word Achebe chooses makes this poem have a very strong impact on the reader. The beginning of the poem where allusion is used in: â€Å"No Madonna and Child could touch† by referring to a famous painting of Jesus and Mother Mary, emphasizes the point of love between the bonds of the mother and child very strongly. Also the strong imagery in â€Å"her eyes the ghost of a mother’s pride† gives an impression of how the mother is hanging onto the child’s life and as the child dies something inside the mother is dying too. These strong images are used often in Achebe’s poem, and because of such his poem have a strong impact on readers and this poem is very memorable. In Hardy’s poem it was very effective as the negative poetic techniques he uses describes about love in a very vivid and strong, also Plena Timoris gives an impact to readers because it shows very clearly the differences between love and death. The juxtaposition in† till hopeless despair began† gives a contrast between hope. By this phrase love is being described very negatively, and because of this the poem is very vivid in the readers mind. Also in the phrase â€Å"the girl’s heart shuddered; it seemed as to free her†. The semi colon used in this phrase is an intended pause to emphasize the sense of the women’s heart actually shuddering. Plena Timoris creates a strong impact on readers as the descriptive words he chooses allows the reader to imagine clearly what is happening. Personally I liked Refugee Mother and Child the most because Achebe boldly states that the human spirit and dignity of the Nigerian mother and the love she has for the child is greater than anything comparable in the Christian world. Though Hardy’s and Rossetti’s poem was not unforgettable pieces of work, I think Achebe’s is the better one because his comparisons stood out more than the ones Hardy had. Also the imagery he had and alliteration was stronger than Rossetti’s. By reading Achebe’s poem I felt and sympathized for the mother and child, and I thought the poets point was put forward very clearly on love and how strong it can be.

Hazardous And Industrial Waste Disposal Issues Environmental Sciences Essay

Hazardous And Industrial Waste Disposal Issues Environmental Sciences Essay The handling of the hazardous materials is complicated by the increasing magnitude of waste generated each year, the variety of materials that become refuse, the vast array of chemicals that may eventually leak from containers and burial sites; the difficulty of monitoring landfill sites for leachates, the difficulty of adequately sequestering waste to inhibit leaching, the variability of soils and their sorption capacities for leachates, the variability of soil permeability, and the cost of safe disposal versus that of assessing real or imaginary risk (Chian, E.S.K., and DeWalle, F. B., 2001). Due to these complexities, the removal of the hazard from hazardous wastes requires a systems approach (Brunner, D. R., and Carnes, R. A., 2004). For example, the least cost of an activated sludge and carbon adsorption system is a function of both processes operating simultaneously. The optimal design range for the least-cost system could not be ascertained by assessing the performance of the two processes independently. Background of the Study An important consideration over the next several years will be the impact of the toxic effluent limitations which should be discussed in the Philippine Government. A rational approach to defining toxic and hazardous wastes is to view a biological entity in equilibrium with its environment and attempt to quantify those insults on the biological entity that causes a disequilibrium or negative response. In the study of hazardous substances, two parameters of importance are dose and time (Atkins, P. R., 1998). An important point to note about the tests for acute and chronic toxicity is that, although the tests might isolate the relative toxicity of a substance, they are virtually useless for predicting levels at which no toxic effects will occur. The decision to incinerate depends on the type of hazardous solid waste, moisture content, organic fraction, heat content, economics, and the availability of land (Fennelly, P. F., et al., 1999). Whenever feasible, incineration should be considered. This process significantly reduces the volume, generally will also detoxify the waste, and gives a product amenable to compaction and containerization resulting in enhanced ease of handling. Incineration processes include the stationary hearth incinerator, the multiple hearth furnaces, the rotary kiln, the fluidized bed reactor, and the open pit incinerator. Each type of incinerator operates properly only within a limited range of temperatures. Generally speaking, for efficient operation, the materials burned must have a fairly uniform BTU value. This may require the blending and mixing of wastes to be burned and the addition of auxiliary fuel. Capital costs for incinerators are high, particularly for the smaller units. In some cases, com plete elimination of the hazardous agent may be obtained through incineration. The result is that potentially toxic and hazardous substances can be identified, but criteria for safe exposure are lacking; therefore, these wastes have a special stigma imposed on them because of the possibility of unknown effects (Farb, D., 2007). This psychological stigma can often impede rational implementation of treatment and ultimate disposal schemes for these toxic and hazardous wastes. No matter what treatment or ultimate disposal scheme is selected, man-made residuals will eventually reside in the atmosphere, lithosphere, or hydrosphere. Objective of the study An understanding of the reactions and forces controlling the movement of a pollutant in the environment is essential if effective treatment and ultimate disposal of toxic and hazardous wastes is to be attained. For example, decisions involving chemical waste disposal will be based on knowledge of chemical form, persistence, acute or chronic toxicity, genetic effect, flammability and reactivity. Hypothesis (Null Hypothesis) There is no environmental effect from hazardous and industrial wastes. Significance of the study A study of the natural environmental forces and reactions which maintain equilibrium of systems illustrates quite well the basic principles of handling toxic and hazardous substances by transforming them into less harmful substances or isolating them in a repository such that release into the dynamic parts of the environment occurs at such a low rate that toxic effects are not realized. Literature Review The greatest fallacy with the environmental crisis and residuals disposal is that acceptable environment can be obtained by reducing or even abolishing our dependence on technology or by neglecting cost considerations. The fact is that residual wastes and their ultimate disposal will require technological solutions-and many of them. Finally the cost to support waste treatment, recycle, reuse, collection and disposal must be borne by the consumer in the form of higher prices and by the taxpayer in the form of higher taxes. The handling and disposal of toxic and hazardous wastes is a multipronged problem that involves: (a) separation and waste partitioning, including process control through technological improvement, waste stream separation, and recycling; (b) inplant waste treatment, including chemical, physical, and biological treatment; (c) in-plant waste disposal, involving recycling, containerization, and incineration; (d) volume reduction through drying, incineration, and compaction of end-of-pipe residuals; (e) translocation involving storage, containment, and transportation; and (f) ultimate disposal considering isolation through minimization of water movement, and maximization of passive barriers through which migration of hazardous materials might take place. Separation and waste partitioning have the distinct advantage of reducing the volume of solid wastes to be handled. Process control entails separating the hazardous agents at the source. The initiation of control on the toxic wastes at this point is the most cost effective with respect to minimizing the volume and segregating the hazardous wastes. Chemical treatment schemes involving techniques based on chemical precipitation, oxidation, photochemical degradation, and pH adjustment can be employed to isolate or detoxify certain hazardous agents. Toxic heavy metals such as lead and cadmium can be isolated by hydroxide precipitation (Rouse, J. V., 2004). In liquid waste streams, numerous physical treatment schemes are possible for separation and partitioning of the hazardous agents. The bulk form of the solid wastes limits the implementation of most physical treatment techniques. Biodegradation of hazardous substances such as certain hydrocarbons, pesticides, and heavy metals (cyanide, for example), has been the subject of a number of studies. Soils, particularly the surface horizon to a depth of 1-3 ft (0.3-0.9 m), contain large numbers and varieties of aerobic, facultative, and obligate anaerobic organisms which singly or together can provide an effective biological detoxification of certain hazardous agents. Two techniques are usually employed to achieve this component of the multiple barrier concepts. These are containment and encasement. Encasement is usually combined with one or more storage methods. The burial site itself, with proper use of clays or other liner materials, can become a container. This aspect of the multiple barrier concepts is more effective in reducing water movement than maintenance of physical integrity. A method of improving the passive barrier is encasement. The use of concrete as an encasement material is widespread. More recently, an interest in developing technology for encasement in plastics and vitreous materials has been expressed. Various encasement materials include: polyethylene, asphalt, lime/fly ash, portland cement, plaster of Paris, metal silicate, bentonite, and vermiculite. Data Treatment and statistical Tools The study is a quantitative study that will focus on data that presents environmental effects of hazardous and industrial waste. They will get the data from the Department of Environment and Natural Resources from year 1988-2008, to uphold consistency and prevent bias. The researcher will be using T-test to be able to test the significance of the variables. Summary and Conclusion Ultimately, residuals must be returned to air, land, or the oceans. The cost of disposal will be borne by the consumer, because residual wastes are generated when natural resources are processed for mans benefit. There is a large and growing body of technical literature on waste management. Hazardous agents can be removed from wastes, although under some circumstances it is more economical to modify the manufacturing process rather than modify sections of the treatment train. Recommendations The removal of hazardous agents is not simply a process that occurs at any one step in a well engineered system. The materials and design of the disposal site itself afford mechanisms for detoxifying and rendering innocuous the hazardous agents in the waste. Through the use of properly engineered treatment systems and passive but multiple barriers between residuals and the biosphere, it is possible to reduce the transport of potential pollutants to environmentally acceptable levels.
