Internet and Technology Hazards :: Essays Papers

Internet and Technology Hazards Computers and the Internet are great items for the household, but along with these advantages there are disadvantages. They are constantly changing the way that we live and do business. The Internet puts tons of information at a click of a button. This information is a great educational tool for children. The Internet can be very dangerous to young children, and there is also research being done now about possible problems that adults have with computers. It is the parents’ responsibility to make sure that the Internet is a safe place for their children. I read an article called Internet and Computer Technology Hazards: Perspectives For Family Counseling. The author of this article is Jo Ann Oravec. It appeared in the British Journal of Guidance & Counseling, in August of 2000. I agreed with almost everything that she wrote. It was an interesting and compelling article. The main reason that people watch the news, and look through various sources of information is to make sure that their homes are safe from possible nuisances in the neighborhood or from severe weather. When working with a network, a series of computers tied together, there are new and dangerous hazards that can go unnoticed. Viruses and security breaches by hackers are a few of the hazards that they may encounter. The Internet is being used more and more for daily life. For many families the meaning of â€Å"Neighbor† is quickly changing from the people that live close to on-line relationships that they have. Now many people are doing their shopping, banking and other everyday activities on-line. Some people are also using the Internet to stay in touch with family members that live elsewhere. As families perform important educational and community activities on-line the meaning of home is changing at a rapid pace. Some families are worried that the Internet could have an effect on their privacy. The privacy for a family is necessary to raising their children. Today it is possible to get information on nearly anyone via the Internet. Crimes such as hacking and identity theft are the main concerns of these families. Children may accidentally give out family information to marketers by filling out their on-line surveys. Many families believe that they could prevent these things from happening by shutting off contact with the Internet.

Banning Catcher in the Rye Essay

The Catcher in the Rye by J. D. Salinger should not be banned in schools based solely on the fact that it is a controversial book that uses harsh language and sexual references. This book is J. D. Salinger’s freedom of speech, and it is a violation of the first amendment for schools to ban this book. This book is only offering an inside look into what teenagers go through in some point of their lives. According to the Los Angeles Times, The Catcher in the Rye’s, â€Å"†¦ profanity and sexual references drew scandalized reactions†¦Ã¢â‚¬  (Rotella 18). Although this book has many sexual references, it is not in any way as explicit and as bad as what teenagers see and hear nowadays on television and in the world. Holden occasionally thinks and talks about sex: â€Å"Most guys at Pencey talked about having sexual intercourse with girls all the time. † (Salinger 48). The average teenager often thinks and talks about sex. It is not unusual for teenagers to do this. The profanity in this book is also not as bad as it may seem. Patty Salazar, a concerned mother and religious activist, claims that, â€Å"‘It uses the Lord’s name in vain 200 times’† (Rotella 17), but the curse words used in The Catcher in the Rye are nothing that teenagers have not heard before in their everyday lives. Banning The Catcher in the Rye in school is not acceptable. It is a violation of the first amendment, and it is nothing far from what teenagers encounter everyday. This book gives teenagers someone in literature that they are able to relate to in one way or another. The Catcher in the Rye is not a book that will corrupt young readers. The underlying theme of this book is loss of innocence. This loss occurs when a teenager makes the change to adulthood where he or she is obscured by phoniness. By banning this book from schools, the only thing that teenagers would be sheltered from is reality.

Rhetorical Analysis Of Slavery In The Declaration Of...

Benjamin Banneker was many things such as a slave, farmer, astronomer, mathematician, surveyor and author. He was always an advocate against slavery, he even wrote a letter to Thomas Jefferson about it. In his letter he mentioned how freedom was a blessing from heaven, cited a part from the Declaration of Independence, and even made a reference to someone in the Bible. He used many rhetorical strategies to help argue that slavery should be outlawed, for example ethos, religious appeals, and pathos.

Women often keep things to do with children from their partners and husbands, so as not to cause trouble and issues for their children. They are the mother hen, the protector, so they take on a lot of burden which can lead to depression and sometimes lead to major breakdowns. Question 1.3: Analyse why depression often carries a lot of social stigma. One of the main issues that people who suffer from depression have to deal with is the social stigma surrounding it. Depression is classed as a Mental Illness; therefore, they have to deal with the perceptions of other people around them. People try to live a normal life whilst those around them look at them differently. This includes; employers, co-workers, family and friends who have known them for long periods of time. They all start to view them differently. A lot of people wrongly assume that people with a mental illness are violent and potentially dangerous. People are afraid and this shows in their attitudes and general persona’s. People are afraid of what they simply don’t understand.

The Influence Of Sulphur Dioxide Emissions Environmental Sciences Essay Free Essays

Biogeochemical cycling is the term which describes the transportation of chemical elements and compounds between compartments, whilst taking into consideration the influences of biology. ( Harrison. R. We will write a custom essay sample on The Influence Of Sulphur Dioxide Emissions Environmental Sciences Essay or any similar topic only for you Order Now M and Mora. S. J, 1996 ) . Anthropogenetic activities can impact on these rhythms, for case the consequence of sulfur dioxide emanations on the sulphur rhythm. A big proportion of these sulfurs dioxide emanations are sourced from the combustion of fossil fuels ( Hewitt and Jackson, 2009 ) , which has given rise to an addition in atmospheric deposition of sulfur, a term we may recognize as acerb rain. The undermentioned treatment analyses the beginning of these emanations, how they cause acerb deposition and the effects of it. The sulphur rhythm is comparatively complex and involves several gaseous species ( Manahan, 2005 ) . On land it is found chiefly as sulfide and sulfate ores, whereas in the oceans, it is present as dissolved sulfate ( Cullis and Hirschler, 1980 ) . In the ambiance the key sulphur compounds include hydrogen sulfide, sulfur dioxide and sulfate aerosols and mists, where in footings of pollution the presence of sulfur dioxide is the most important portion of the sulphur rhythm ( Manahan, 2000 ) . The rhythm operates whereby sulfur is continuously transported between the different stages. Ivanov ( 1981 ) has attempted to place the major sulfur fluxes of both anthropogenetic and natural beginnings. Annually about 120b Tg S are extracted by adult male from the geosphere in fossil fuels and sulfur incorporating natural stuffs for the chemical industry. Of this sum 70 Tg S are emitted to the ambiance. Around half of the staying 50 Tg S straight enters rivers, and another portion is applied wi th fertilisers to agricultural land. Natural beginnings lending to the sulphur rhythm include 29 Tg yr-l from volcanic gases. River overflow is the major transportation of sulfur from continents to the ocean with an one-year burden of 224 Tg, where 109 Tg of this is accounted for by anthropogenetic pollution. The entire flux of assorted sulfurs signifiers from pelagic H2O to deposits and farther to the lithosphere sums to 130 Tg yr-l. Anthropogenic sulfur fluxes have now reached a degree that is comparable with natural fluxes and this is expected to increase in most parts of the universe ( Ivanov, 1981 ) . Sulphur dioxide emanations are now one of the largest fluxed in the sulphur rhythm. Sulphur dioxide can arise from natural and semisynthetic beginnings. Natural beginnings include gases from vents, forest fires and from the oxidization of other sulphur compounds such as H sulfide ( Environment Agency, 2010 ) . On the other manus, anthropogenetic activities ensuing in sulfur dioxide emanations include the smelting of ores, warming of pyrites, sulfur excavation and burning of fossil fuels ( Moller, 1984 ) . We are chiefly interested in the emanations from the combustion of fossils fuels, since the oncoming of the industrial revolution has increased the sulfur load in the ambiance dramatically. Hewitt and Jackson ( 2009 ) stated that the anthropogenetic part to the entire sulphur emanation budget, chiefly in the signifier of sulfur dioxide, approaches 75 % , with around 90 % of this derivation from the northern hemisphere. The most abundant beginning of atmospheric sulfur is the combustion of coal and its byproduct ; nevertheless this is hard to quantify due to the ass ortment of coals such as difficult coal, lignite and coal for cookery ( Cullis and Hirschler, 1980 ) . The following most of import beginning of atmospheric sulfur is the combustion of crude oil merchandises, where the coevals of sulfur from this is still increasing ( Cullis and Hirschler, 1980 ) . Even in the absence of air pollution, rain H2O is somewhat acidic ( pH 5.6 ) due to the presence of C dioxide, therefore why the phrase acid rain refers to rain with a pH of below 5 ( Clarke and Tomlin, 1999 ) . Acid rain is caused by sulfur and N oxides come ining the ambiance, where they are converted to sulphuric and azotic acids severally. When these combine with hydrochloric acid from lifting H chloride emanations, these acids so cause acidic precipitation ( Manahan, 2005 ) . Acid deposition is the general term for acid rain, acerb sleet and acid snow etc. There are two types of deposition, moisture and prohibitionist, where moisture involves the transition of sulfur dioxide to sulphuric acid in the presence of wet from the ambiance, and dry deposition occurs when sulfuric acid is converted into sulfate atoms which straight hit the Earth ‘s surface ( Hill, 1997 ) .The same applies to nitrogen oxide. Beginnings of nitrogen oxide include buoy uping and natural combustion of biomass whereas for semisynthetic beginnings the chief 1 is vehicle emanations ( Clarke et al, 2001 ) . Sulphur dioxide is oxidised in the ambiance by a figure of mechanism. In low humidness conditions the most of import reaction is with the hydroxyl extremist ( Harrison and Mora, 1996 ) : SOa‚‚ + OH HOSOa‚‚ HOSOa‚‚ + Oa‚‚ SOa‚? + HOa‚‚ SOa‚? + Ha‚‚O Ha‚‚SOa‚„ Due to sulfuric acid ‘s low vapor force per unit area it can quickly attach to the condensed stage such as aerosol atoms. The majority of Ha‚‚SOa‚„ is lost via wet deposition mechanisms in cloud droplets and precipitation ( Hewitt and Jackson, 2009 ) . In wetting agent climes different reactions occur since cloud H2O droplets are of import in transition of sulfur dioxide to sulfuric acid. When sulfur dioxide is dissolved in H2O it is in equilibrium with sulphite and bisulphite ions. This can be seen in the undermentioned equations ( Harrison and Mora, 1996 ) : SOa‚‚ ( g ) + Ha‚‚O a†¡? SOa‚‚ ( aq ) SOa‚‚ ( aq ) + Ha‚‚O a†¡? Ha‚?Oa + HSOa‚?a? » HSOa‚?a? » + Ha‚‚O a†¡? Ha‚?Oa + SOa‚a? » Sulphite may be oxidised by atmospheric O but this is a slow procedure unless it is catalysed by a passage metal ion such as Fe. The overall procedure can be seen below, which shows how sulfurous acid, which is a weak acid is converted to Ha‚‚SOa‚„ , a stronger acid ( Harrison and Mora, 1996 ) : 2SOa‚a? » + Oa‚‚ 2SOa‚„?a? » Sulphur dioxide has a short mean abode clip as it has an atmospheric life-time of yearss, so it may come in the free troposphere but is improbable to come in the stratosphere ( Harrison, 1999 ) . This makes it a regional job since the gas does non transcend the planetary horizontal commixture clip, so it can do taint of the ambiance, hydrosphere, and dirt ( Ivanov, 1981 ) . ‘Sulphur emanations lead to acid deposition far from the beginning ‘ ( UNDP, 2000 ) and can hold inauspicious effects on aquatic ecosystems, trees, dirt and substructure. Schindler ( 1988 ) stated that it is now clear that acid rain has caused widespread acidification of many aquatic ecosystems in the north eastern United States, Canada, Norway, Sweden, and the United Kingdom. Recent information has shown that juvenile fishes and other beings lower in the nutrient web have seen to be intolerant to higher pH values ( Schindler, 1988 ) . This can do trouble at higher trophic degrees as marauding fish may hunger, which can be the cause of decease even before the direct toxication of the H ion ( Schindler, 1988 ) . Persson ( 1981 ) besides found a lessening in reproduction caused by egg and fry mortality, which once more can impact further up the nutrient web. Damage to woods by acerb rain became noticeable in Germany in the early 1980s, shortly following this other states besides reported similar incidences ( Harrison, 1999 ) . Numerous field and research lab surveies have taken topographic point in peculiar with the ruddy spruce in the Northern hemisphere, as it has suffered widespread freezing hurt, growing decrease and mortality ( DeHayes et al, 1999 ) . The freezing hurt instances in ruddy spruce woods has increased over the past 40 old ages, which coincides with the clip of increased emanations of sulfur and N oxides. However the mechanism for the ruddy spruce diminution is non clearly understood. One account is that exposure of trees to promote SOa‚„?a? » in acerb rain may change C metamorphosis of trees, which can worsen the effects of natural emphasis such as cold and drouth ( Schindler, 1988 ) . Another theory is that acerb deposition mobilizes aluminum in the dirt which reduces soils storage of Ca and its handiness for root consumption. Freezing hurt consequences in the loss of leaf which is critical for photosynthesis and hence growing ( DeHayes et al, 1999 ) . Acid deposition can do corrosion on edifices constructed of limestone such as celebrated cathedrals. In damp conditions sulphur dioxide will change over Ca to carbonate to gypsum ( CaSOa‚„ ) which is more soluble than carbonate, therefore the reacted rock can be removed by disintegration ( Harrison, 1999 ) . Solid gypsum occupies a larger volume than carbonate which leads to flaking and checking of stuff from the surface. To reason we can see that sulfur dioxide emanations from the burning of fossil fuels have greatly impacted on the sulfur rhythm, peculiarly in the last 100 old ages, to the extent where it is now the largest flux in the rhythm. One of the remotion mechanisms of sulfur dioxide emanations is acerb deposition, which has found to hold had black effects on aquatic ecosystems, trees and workss and substructure. Reducing these emanations would be good to the latter and may reconstruct the anthropogenetic flux to a degree below the natural flux in the rhythm.

My Grandmother free essay sample

My biggest fear has always been being alone. The idea of not having any company and losing my loved ones has always been such a tough subject for me to talk about with anyone, including myself. There comes a point in life though where you have to let go and cope with your loss of someone that you are close with. I have learned growing up that nothing always stay the same and that there is always an ending to something. My grandmother’s death was the experience that taught me how to cope with this loss. I could say that the closest I ever got to my father was my paternal grandmother since I barely interacted with my father. She would tell me stories about him growing up and how he is in general. I had always slept in his old room when I would sleep over and look through their old albums.

Not having my father around growing up has made me feel like I am not wanted and lonely. My grandmother was also someone who I had also considered as a friend. We would do arts and crafts on her patio while eating cookies and cracking jokes. I would not call her by â€Å"grandma† or â€Å"ma†; I would call her by her name, â€Å"Brit.† Brit was a great friend to have who was always there for me. Two-thousand seven was a big year for me because everything was changing for me: new school, new car, new pets, and new experiences. I was so busy that year that I was not visiting, or talking to Brit as frequently as I usually did. Every time I asked, my mom if I could see her, my mom would make up some excuse that she was too â€Å"busy to see me right now.† In the back of my mind, I knew that something was wrong but I was too blind to realize what was happening to her. The last time I had seen my grandmother was my seventh birthday; I remember celebrating my birthday over at my grandparents’ house. My mother and grandfather told me that Brit could not cook and that I could only see her in the master bedroom. Walking into the master bedroom, I remember how awful it smelled and how something felt different. I took one look at Brit and she looked so sick, she could barely speak to me that night; she was hooked to a device that went over her mouth that now thinking about it, was giving her oxygen to breathe. She had given me a ton of her teddy bears and keepsakes for my birthday. â€Å"Why are you giving me all of your stuff?† I asked her while she gave me her gifts. â€Å"Kaylin, I want you to remember me no matter,† she had replied weakly. I completely disregarded any of the clues that I could have used to put together the fact that she was sick with lung cancer and her life was ending. Late on Christmas Eve, my grandfather had left a voicemail for my mom and me that Brit had passed away. I remember how miserable I felt that night going to sleep; I was crying the whole night with one of Brit’s teddy bears in my arms and wishing that she did not die. Christmas is not a time to cry and mourn the loss of a loved one, it was a time to cherish with them. For weeks, I would feel sad every now and then when I thought about Brit and how I could not see her anymore. My mom told me eventually that even though she was gone, that she would always be with me in my heart and that I should celebrate her life, not that she was dead. I knew that when my mom gave me a piece of advice that I should let go of Brit, it was my time to move on and enjoy the rest of my life, not to be miserable and cry over someone. To this day, I still visit my grandparents’ house ever few years since my grandfather has not really been in contact with us since Brit died. When I went over to their house in May, I remember that the house did not feel like the warm, cozy place that was so familiar when growing up as a child. The thing I remember the most being there was that Brit’s old decorations and plants were still there which made me smile a bit because it made me feel like she was still alive and with us. I still remember her every once in a blue moon which makes me a little melancholic every now and then. One thing I know is though that Brit will always be a special person to me who taught me how to cope with the loss of someone.
