Technological issue in homeland security Case Study

Technological issue in homeland security - Case Study Example According to Vacca (2007), the internet has led to vast transformations in the Homeland Security. For many years, the internet has been utilized to enhance communication between terrorists. The terrorists are also utilizing the internet as a recruiting tool, and support of terrorist organizations; it is through the internet that various terrorist organizations communicate and advise each other on the tactics to use in attacking their enemies. The internet has also enabled Homeland Security to get information in a cheap and easy manner; obtaining of information through the internet is easy since, at a single click, Homeland Security can have a lot of information. This has helped the Homeland Security to detect any threats to security and act promptly, thus eliminating issues of terrorism. Sharing of information from one individual to another over the globe has been necessitated through the use of the internet. Hence, the Homeland Security can access terrorism information over the globe through the use of the internet. This terrorist information is usually crucial in eliminating terrorist activities and improving security. On the side of Homeland security, the internet has been an excellent tool since it has assisted the department in identifying individuals who may be terrorists through the use of biometric technology (Alperen, 2011). According to biometric technology, every person possesses certain traits; behavioral and physical, which identify people in a unique manner. The internet has made the revelation of operations done by the Homeland Security officials feasible. Through internet hacking or cyber crimes, the terrorists can access crucial information from the Homeland security website. Because of this problem, the Homeland Security has increased cyber intelligence through seeking Information Technology professionals to assist in tracking of the terrorist activities on the

I had a dream about you Essay Example for Free

I had a dream about you Essay The beginning of the poem is about a dream reflecting the beginning of a relationship, or more specifically, your relationship. In your dream it seems you had a lot of fun, throwing oranges at your boyfriend, and all the kisses. In the next dream, you’re progressing in the relationship, and things get a bit more serious and realistic. In the last dream he seems to be getting annoyed with you, even though you’re the same. You stay a static character and he isn’t, in the dreams. Seeing that dreams are a reflection of real life, he begins to become annoyed with you as he grows sicker, and things become serious. In the next dream you could see he was growing sicker, and that he was going to die. With hints like, the sky was red, the sand was red, and the bird-crows- were watching him. You also explained how you could hear his heart beat, and you could hear him breathing. When a person is sick and is very close to death, hearing signs that they are still alive it the most comforting thing you could hear. You also talk about his ribs being delineated like a junkyard dogs, and the hospital, which implies illness, I think aids or Cancer. When you stop talking about the dreams, we are where you were in the relationship at that time, seriousness, and that you needed to stay by his side. When he was on the bridge it just showed that he need you to take care of him, you both needed to be saved. Seeing as both of you couldn’t save yourselves it was a chore to save each other. He asked about if you would love him even more when he was dead, there was a certainty, no hypothetical, which made it scarier. That is why you felt the need to fatten him up, because he knew he was going to die, you wanted to stop the inevitable. When you said you wanted to fat him up, it made me think of chemotherapy which to some degree drains your health, and aids, which does the same.

Vegetarianism Essay -- Healthy Lifestyle Essay

Friday evening. You decided to have a dinner with your friends at the new restaurant. You are promptly seated at the table in a corner and are given menus. Happy mood helps to enjoy the evening. What a varied menu you have here: juicy burgers, foot-long sandwiches, salads, steaks, grilled ribs in barbecue sauce, grilled chicken ... Oh, wait! You are a vegetarian. You are not allowed to eat meat. Your evening is destroyed. Your friends are laughing at you while you’re finishing the second plate of salad, while they are playing with pork ribs. You’ve already prepared to listen to their jokes about vegetarians and answer multiple questions why you stopped eating meat. The situation above often occurred to me. Before I chose a restaurant, I tried to find out what food was served there. I was vegetarian for over five years. And all these five years I ate no fish, no meat, no chicken, but only vegetables, fruits, nuts and cereals. I thought such an abundance of nutrient was sufficient for my organism, but my body was saying otherwise. A few months later, after the rejection of meat food and consumption of vegetables only, I started to feel the malnutrition. Hunger followed me constantly. Despite the fact that I could eat a lot, a half an hour later, I was so hungry and had to look for something else to eat. Then, health problems began. Depression, emotional imbalance, fatigue, weakness, apathy, poor sleep – this was just a small list of disorders that I have gained by eating vegetables. When I stopped eating meat, I didn’t know what it was like to be a vegetarian. I wasn’t aware of what I should have eaten and how. During this lo ng five years, I learned a lot about vegetarianism and found out it’s not even close to what people think i... ...rom harmful thoughts and teaches the discipline and the patience. It’s important to remember that vegetarianism is a short-term diet and should not be extended over a long period of time. Otherwise, it will bring harm and destruction to the body. Vegetarianism taught me a good lesson. I began to feel my body and to listen to its signals. I am pleased to share my experiences with my friends. I try to show them the pros and cons of this diet. Smart people learn in someone’s mistake. I wasn’t smart enough and started five-year long experiment to understand how it’s like to be a vegetarian. At the end of my â€Å"journey†, I came up to conclusion that good nutrition should be diversified. We can not live without vegetables, eating only meat and vice versa. We need to combine meat products with plant food in order to maintain healthy lifestyle and enjoy our lives in full.

Harry Potter’s Influence on Society Essay

â€Å"It’s important to remember that we all have magic inside us.† (J.K. Rowling, scholastic book fair promotion, October 1999) One of the most influential novels of this generation is the Harry Potter Saga. Since the first book was published in 1997 these novels take you on a breath-taking adventure through witch-craft and wizardry. How has this saga written by J.K. Rowling been an influence on society you ask? Come explore how Hogwarts the school of witch-craft and wizardry made its way from a small fantasy school in England to a worldwide phenomenon. It all starts with the author; J.K Rowling is the master-mind behind these magical books. Born on July 31st, 1965 as Joanne Rowling she decided to go under the name J.K for her books. She chose this because her key target readers were young boys and she thought that they would not want to read a book by a female author although she was mistaken. The idea came to her while she was on a four hour delayed train trip from Manchester, England to London. She saw a young boy sitting across from her and started to create a story for this him. She decided his name would be Harry and he was on his way to attend his first year at a school as a wizard. This is what started the successful journey that would change reading for our generation. The Harry Potter saga is made up of seven novels. (Listed below in order) * Harry Potter and the Philosophers Stone ( Sorcerer’s Stone) * Harry Potter and the Chamber of Secrets * Harry Potter and the Prisoner of Azkaban * Harry Potter and the Goblet of Fire * Harry Potter and the Order of the Phoenix * Harry Potter and the Half –Blood Prince * Harry Potter and the Deathly Hallows These books follow the life of Harry Potter a young wizard who has been through something you cannot imagine. Both of his parents were murdered when he was just a baby by Lord Voldemort ( who plays the villain in the story). Harry Potter was present while this happened but he survived the killing curse with only a minor scar on his forehead. He survived because mother’s love for him was so powerful that it somehow protected him from the curse that took his parents lives. Since he was orphaned he was living with his aunt, uncle and cousin just outside of London, England. When he turned eleven years old he received an invitation to attend the Hogwarts school of Witch-craft and Wizardry because he was wizard. While on his way to Hogwarts he comes to learn that he is famous for the events that lead him to have just mere scar on his forehead and being the only wizard to survive a killing curse. On the Hogwarts express he meets two young wizards who eventually become his best friends, Hermione Granger, and Ron Weasely. Each book is a new school year which comes with new tasks and new level of maturity. Throughout the novels we come to understand that Harry Potter has the same problems as a everyday teenager but there is extra level of responsibility because along with magic comes consequences. There is two ways that magic can be used. There’s good magic but there is also dark magic and both of these are seen within the Harry Potter novels. Voldemort being the villain is constantly in a fight with Harry. This is where the theme of the story comes in. The theme of the Harry Potter novels is good vs. evil. Harry represents the good character and Voldemort represents the evil. The only way for Harry to be free of the evil spirit is to kill him. Harry uses dark magic to do so but uses it in defense. Along every step of the way Harry’s two best friends where there to help. When he needed advice or someone to lean on the both Ron and Hermione were always there. Without them Harry Potter would never have been able to demolish the evil character and enjoy his life to the fullest. That is the moral of the story, love can overcome evil and if you have support system you can do anything. That is something as human beings we should keep with us for all time. Morals are something we can learn from reading but because sometimes we get distracted by technology and materialistic items we forget that. J.K Rowling was taking on a generation that was attached to technology and attracting them back to reading. This may be the largest impact the Harry Potter Saga has had on society. Reading is somehow lost in this generation and many people do not realize the importa nce of reading. Reading enhances vocabulary, helps speech, and really broadens a person’s understanding and tolerance. Reading always teaches you something, from Harry Potter we learn that evil cannot stand in the way of love, and no matter what has happened you can always get through it if you have people to support you. J.K Rowling also focused on one other important detail, imagination. Reading allows you to use your imagination to come up with scenarios for you self. It allows you to build your artistic ability and creativity by doing so. Creativity stems from imagination; this means without an active imagination there would be no creativity whatsoever. Imagination allows you to transport into a fantasy world and experience things you would not be able to in reality. One important thing about imagination and creativity is that is undefined. Every single person views it differently and there is no right or wrong answer. J.K Rowling took this into consideration while writing her books and many people think because she created such a conversely topic that it opened the public up to the books. But one thing everyone can agree on is that this book changed our generation. Michelle McMorrow Ramsell the director of Tuscarawas Public Library says in a news paper article that: â€Å"The popularity of the Harry Potter series made reading a cool thing and made reading a cool thing to talk about with friends. The time that Harry Potter was released was is when technology started to become a major part in our generation. Harry Potter books got millions of people involved from the middle-school age level and up.† This is one of the reasons Harry Potter is such an influential book. Not only did it bring people back into reading but it also has characters that people can relate to. J.K Rowling started to write because she was an English major and it was a passion of hers but as she got more into depth with the books she started to make all the characters relatable. She started writing the book when her mother fell ill, but quickly after her mother passed away and that is when she decided she would use this idea for the book. She knew what it felt like to lose someone who was so important so that is where she came up with the idea for Harry to lose his pare nts. Many people know what it is like to lose someone important to them and when someone else dealing with the same thing it makes you feel like you are not alone. J.K Rowling was diagnosed with clinical depression in 1993, she needed a way to escape real life and she chose this with Harry Potter. She decided to add the dementors, the creatures who are known as the soul-sucking creatures who are constantly after Harry because of the way she felt. She thought that a good way to come out of depression is to be sidetracked in a way, and Harry Potter was her way out of reality and she took that into consideration. She also tried to relate most of her characters to people she knew when she was younger. J.K Rowling says that she sees a lot of herself in Hermione. Hermione comes off as a know it all sometimes and J.K says that’s how many people saw her when she was young. The Wesely’s were a poor family that did not have much, she was able to relate to this because before Harry Pot ter she was in that place for a long time. Ron was also based on J.K Rowling’s best friend Shane Harris. She also saw herself as Harry because there was always something she was trying to fix and she was not a quitter. She was never going to give up in what she believed in and it helped her get through many hardships she faced throughout her life just like him. Reading books can allow you to escape reality and maybe even sometimes solve a problem which is what she was trying to accomplish. The Harry Potter books were such a success that they were turned into a film series starring Daniel Radcliffe, Rupert Grint and Emma Watson. The entire film series made 7.7 billion dollars and is also one of the top highest grossing films of all time. The first movie premiered in 2001 and the last being in two parts finished in 2011. Over the last ten years J.K Rowling worked closely with the script writers because she wanted it as close to the books as possible. The movies success made the young actors Hollywood superstars and it al so had a huge impact to our generation. The movies and books are translated into 67 different languages, so no matter where you live or what language you speak you can get a taste of the magic. It was a family movie that everyone can enjoy together and seeing the magic come alive on screen really touched people all over the world and that also made an impact on society. Many things have evolved from the novels and the movie is not the only one. On June 18th 2010, Universal Studio’s opened up a new Theme park named: The Wizarding world of Harry Potter. Here you can experience the magic of Hogwarts in real life. You can you visit the Hogwarts castle, Three-broom sticks diner, Honeydukes sweet shop, Ollivander’s wand shop, Zonko’s joke store, and dervish and banges quidditch equipment store. These are all places that are in the movies and books and after ten years there finally a reality. â€Å"I used to leave set wishing I was at Hogwarts and that Harry Potter was real life. I got to experience the magi c of it but normal kids didn’t and now because of the theme park they can, and it’s wicked.† – Daniel Radcliffe( interview in 2010 about the Theme Park) This is a huge impact on society because there is not anything like this visting the theme park gives you the full experience and your imagination really comes to life. Daniel Radcliffe believes that â€Å"The wizarding world of Harry Potter has the potential to be a fantastic memory that kids will take with them, that will be something that stands out with them for a long time.† ( interview about the theme park 2010) This is a true fact and everyone who visits seems to capture some of the joy and take it with them where ever they may go. Pottermore is also another place to experience the Hogwarts school of witch-craft and wizardry. A website created by J.K Rowling in order to keep the Harry Potter Saga alive after the seventh book and the eighth movie being completed. She did this in response to her fan base being so strong. â€Å"So I’d like to take this opportunity to say thank you because no author could of asked for a more wonderful, diverse readership. I’m thrilled to say that I’m now in a position to give you something unique. An online reading experience unlike any other and its called Pottermore. It’s the same story with a few crucial editions; the most important one is you. Just as the experience of reading requires the imagination of the author and reader work together to create the story, so Pottermore will be built in part by you the reader. The digital generation will be able to enjoy a safe, unique online reading experience built around the Harry Potter books. Pottermore will be the place where fans of any age can share, participate in and re-discover the stories. And I will be sharing additional information that I’ve been holding for years about the world of Harry Potter. I hope to see you soon.† (J.K. Rowling on Pottermore.com) By visiting this website you can go through journeys of the books and through every chapter you visit you learn something new about the wizarding world. Like the books and movies you get sorted into a house: Gryffindor, Ravenclaw, Hufflepuff, and Slytherin, here you get to experience life as if you were a student. Just like the book you earn house points, make friends from many houses, brew positions, casts spells, attend quidditch matches , take journeys through diagon ailey ( located in London where the shops are), visit the wizarding bank and really experience life as a virtual Hogwarts student. As you can see the Harry Potter novels really do influence society. There has been over a million copies of the books sold, eight successful films translated into 67 languages, a enchanting theme – park, amazing websites, and even merchandise which includes, shirts, stickers, hats, sweatshirts, wands, anything you can think of. It is a spectacular story that has transformed reading. Most people before the Harry Potter series thought reading was boring and that TV. and the internet were more entertaining, but after reading it they changed their mind. J.K Rowling created an imaginary story that was still relatable and people will remember this book for years to come. â€Å"There’s always room for a story that can transport people to another place, and I feel I completed this task with Harry Potter.† ( J.K. Rowling on the success of her novels.)

History And Effects Of Pesticide Pollution Environmental Sciences Essay

Pesticides have been known to be for 1000s of old ages. Sulfur combustion was a method used in ancient Sumer every bit good as ancient Rome for killing insects ; the Romans were besides known to utilize salt to kill weed ( Wikipedia,2010 ) . In the 1400s, lead, quicksilver and arsenic were efficaciously used for this intent. Similarly, in 1600s, the job of emmets was tackled by the usage of a mixture of honey and arsenic. In the later of portion of the 1800s, US husbandmans used assorted arsenites every bit good as baccy derived functions to command plagues. The greatest enlargement in the pesticides was seen after World War II. Chemicals like DDT, aldrin, diedrin and 2,4 – Calciferol came into usage due to their low cost and high grade of efficaciousness ( Delaplane, 1996 ) . DDT took the bar as pass overing out major part of vectors responsible for typhus and malaria. Although being in being since the latter half of nineteenth century, its true potency was understood in 1939 . It was so successful that the discoverer Paul M & A ; uuml ; llen was awarded Nobel award in 1948 for his accomplishment. It was non until 1962 when the land interrupting book of Rachel Carson, Silent Spring, made a connexion between environment pollution, major wellness jeopardies and DDT. Carson ( 1962 ) argued that the chemicals like DDT are non merely toxic to the insects but to the birds and fish every bit good. It was proposed that this was because of a direct mechanism every bit good as an indirect mechanism.Pesticides use in US and EU:After a prohibition on DDT ‘s usage in the US, the enthusiasm was shifted to production of newer compounds which were safer and better than the conventional 1s and methods of harvest production that discouraged plagues. Integrated pest direction ( IPM ) was introduced like a multipronged scheme to concentrate on newer harvest production methods, increased growing of pest-specific marauders and timing of pesticide spray so that maximal h arm to the plagues could be incurred finally increasing the output ( Delaplane, 1996 ) . It is interesting to observe that the pesticide ingestion has increased dramatically over the last 50 old ages. As opposed to 2kg/ha in 2004, in 1961, it was merely 0.49kg/ha. In one estimation, France and US spray 35 % and 20 % of their entire surface country severally every twelvemonth ( Goodplanet.info, 2010 ) . In malice of holding really powerful newer agents, the figures keep on lifting. Europe represents about one tierce of the universe pesticide market portion standing at 30 billion dollars a twelvemonth. North America and Asia constitute a one-fourth each. US is the taking consumer of the pesticide industry with a figure of 2.5kg/ha. Europe consumes 3kg /ha, while India is at merely 0.5kg/ha. In a study by PAN Europe ( 2007 ) , it was stated that the pesticide ingestion was on the rise despite newer agents that act at a lower dosage. This shows that the pest control is still dependent o n the usage of these merchandises.Pesticides use in United kingdom:It has to be mentioned that in UK the pesticides ‘ usage is controlled by the ( CRD ) .The board of directors controls chemicals ‘ usage where listed under REACH statute law which consist a portion of Europe ‘s statute law where came in force in June of 2007and is responsible for the chemicals ‘ rating, enrollment, limitation and mandate such as guaranting that the companies produce and at the same clip conveyance chemicals under a responsible and safe manner. Furthermore it ensures that the people give a high attending for the protection of the environment by any possible chemical ‘s effects. The CRD is the chief responsible for pesticides ‘ usage limitation in UK.Pesticides and their application:The large inquiry is why they are used†¦Ã¢â‚¬ ¦ ? ? Harmonizing to a study, about one tierce of the agribusiness production is destroyed with the brunt faced by developing states bec ause of plagues. This amounts to a humongous 300 billion dollar one-year losingss with an mean output loss runing from 30 to 40 % ( Plucknett and Kagbo, 2010 ) . So to be faced that job at that place has been appeared particularly the last decennaries a expand usage of pesticides in agricultural industry. Pesticides are used to disrupt onslaughts of snails, animate beings, bullets and snails while at the same clip for the protection of public wellness killing animate beings like mosquitoes, mice and rats. More than 1600 types of different pesticides are listed in the Compendium of Pesticide Common Names. These are classified harmonizing to their country of action such as Herbicides, Insecticides and Nematicides. Other major classs include Acaricides, Antimicrobials, Attractants, Avicides, Fungicide, Molluscicides, Predacides, and Rodenticides ( Wood, 2010 ) . The WHO Recommended Classification of Pesticides by Hazard and Guidelines to Classification 2009, divides these chemical comp ounds into Class Ia compounds, which are highly unsafe, Class Ib as extremely unsafe, Class II as reasonably unsafe, Class III as somewhat unsafe and Class U as improbable to be acutely unsafe based on LD50 for the mice.Mode of pesticides ‘ action:An of import fact worth adverting is that since there are a immense assortment of merchandises available for different types of plagues, likewise there is besides a enormous variableness in the mechanism of action of these pesticides. One chemical may move at one or more critical cellular tract of the plague. Harmonizing to Hayes ‘ Handbook of Pesticide Toxicology ( 2010, pp. 106 – 117 ) , this can be explained for a class of a chemical. Insecticides, Nematicides and Acaricides act as Acetylcholine esterase inhibitors or agonists. Some of them besides block glutamate gated chloride channels and mitochondrial composites. A assortment of them are ryanodine receptor modulators. Pyrethrum derived functions such as pyrethrins and pyrethroids that act on Na channels are speedy in action. Rodenticides may either organize an acute toxin such as phosphine in the tummy of the gnawer or cause hypercalcaemia. Examples include zinc phosphide and bromethalin. Warfarin may exercise an anti-coagulant consequence, therefore the animate being to spontaneously shed blood boulder clay it dies. Herbicides mark works specific mechanisms. They act on photosystems thereby interrupting the respiration of the weed. They besides block amino acid and fatty acerb synthesis and can besides do cell membrane break. Molluscicides disrupt cellular respiration of snails and bullets. Phasmohabditis hermaphrodita ; a infective roundworm, is a biological molluscicide.Behaviour and destiny of pesticides:Pesticides, when applied are either adsorbed, may be transferred to some other location or degraded into non-active constituents depending on the type of pesticide. Adsorption is a procedure by which these chemicals straight bind to the dirt atoms. Transportation is the phenomenon by which these compounds are dispersed off from the application site. Harmonizing to Nebguide ( 1993 ) , soaking up, harvest remotion, leaching, spray impetus and run off. Micro-organisms and workss uptake these compounds by soaking up. Mechanisms like volatilization and run off are of import as they distribute the pesticides to other location to eliminate the plagues but this is non ever the instance as it is besides one of the grounds of environmental pollution. Similarly, spray impetus causes these chemicals to be dispersed to other location at the clip of application. Leaching is dependent on the water-solubility of the pesticide and can either be downwards, upwards or sideways. Degradation takes topographic point either by, microbic action, Sun visible radiation or photodegradation or by a chemical reaction ( Nebguide,1993 ) .Pesticides in surface and land Waterss:In a survey by McBride ( 1989 ) , it has been postulated that H2O â₠¬Ëœs taint hazard is determined by features of the pesticide used, the features of dirt and the H2O volume ; A chemical with high H2O solubility, low dirt surface assimilation, high continuity applied on a coarse and low organic affair dirt with shallow land H2O and frequent irrigations has a high hazard of polluting H2O beginning. In an article by PAN Europe ( 2010 ) , Belgium, France, Netherlands and UK have highest pesticide taint in lowland river countries ; the one-year cost in cleaning up the H2O resource is around 170 million euros in UK yearly with a portion of this load go throughing on to the consumer.Practical solutions for pesticide pollution:Several techniques can be used to minimise the pesticide pollution. Integrated pest direction ( IPM ) is an first-class manner to get down with. It involves a holistic attack of choosing immune works species, cultivation and reconnoitering to minimise the chemical use. There should be repeated cheques on the harvests to mensurate th e pest population before a pesticide onslaught could be ensued. Crop rotary motion methods should be employed to deter the harmful beings. Educational plans should be encouraged so that all the persons involved in the procedure know precisely what they are making. This can be done by strong media runs backed by pertinent statute law. Research into biological and other non-chemical pesticides should be sought for. Pesticide choice should be appropriate and after usage disposal harmonizing to recommended manner. Tanks and reservoirs should ne'er be filled with pesticides while being close to a H2O reservoir to avoid taint. Preferably, a H2O beginning should be covered to forestall pollution. Detailed conditions prognosis should be taken into history before spraying to minimise run off and spray impetus. The equipment used should be in tip top form so that there are no leaks and droplet size is appropriate.
