Must-Read Books for New High School Graduates To Become Engaged Citizens.
Must-Read Books for New High School Graduates To Become Engaged Citizens. Itâs that time of year when high school graduates walk across that stage and out into the world, whether that is straight into the workforce or perhaps onward to college. We asked Rioters to recommend books for new high school graduates to read and hereâs what we came up with. Long Way Down by Jason Reynolds A short book that can be read in one sitting, written in verse, about the epidemic of gun violence in America. This should absolutely be required reading for so many reasons, but most of all because Reynolds created a story thatâs current with so many of the hallmarks we find in the classics that are taught over and over again. Our nationâs students are literally on the front lines of this widespread conflict and they deserve to have authors like Reynolds there to articulate whatâs happening and open an avenue for discussion and understanding. Dana Lee Teaching to Transgress by bell hooks This might seem like an odd choice, since hooksâ intended audience are college teachers, but students can learn so much by considering education from the teacherâs perspective. Particularly in this collection of essays, where hooks explains how college professors need to be more subversive from leading discussions that confront class/race/gender differences to encouraging confessional narratives. Ultimately, she argues for a feminist classroom, and I think by reading this students can learn how they as students can engage with their professors and the question what theyâre learning. I would recommend this for high school grads going off to college. Margaret Kingsbury So You Want to Talk About Race by Ijeoma Oluo Leaving high school and heading into the adult world means that you are going to start being a part of more nuanced conversations on big topics, including the issue of race. This book is a particularly great resource for learning about your own privilege and about the complexities of this topic. Danielle Bourgon We Should All Be Feminists by Chimamanda Ngozi Adichie Let me start by saying yes, I recognize and disagree with the TERF-y nonsense that this author has said and it is not to be taken lightly. In regards to this book in particular, I think there are many things that every new adult should know about the society we live in and ways we treat and support each other. Feminism is for everyone and the earlier we can get that message across in someoneâs life the better off society will be in the future. Patricia Elzie-Tuttle Travel as a Political Act by Rick Steves After high school, I was curious about the world outside of my hometown, but travel was just an abstract concept until I stumbled upon an opportunity to study abroad in college. Now Iâm the biggest evangelist for travel after high school of anyone I know. In this book, Rick Steves talks about the why behind travel by going on the ground in different countries and examining perspectives that seem foreign to a lot of Americans. I think itâs a great book for anyone who hopes to travel abroad at any point, and for those who donât, I think it will convince them why they should if they get a chance. If anything, just by reading the book, the reader gets to try on ideas from cultures all over the world, which will give them a broader perspective on their surroundings and the world at large. Emily Polson Between the World and Me by Ta-Nehisi Coates Though only 150 pages, Between the World and Me is the most powerful book on race in America that I have ever read. Iâm pretty sure my high school self would have struggled with it, because, yes, itâs heavy, and because there are so many layers to it, so much to unpack and exploreand thatâs exactly why I think every high school graduate should read it. Itâs the kind of book that teenagers should struggle with. Coates does something exceedingly rare: this book is written in stunningly beautiful prose, full of perfect sentences that took my breath away, and it is also incredibly smart and deeply relevant. Itâs not a book written for white people, but itâs one that white people absolutely should read, and so teenagers of different races will have vastly different experiences reading it. Thatâs another reason this book should be required reading for high school grads: it will spark real, hard, and honest thought and conversation. Laura Sackton

In doing so, please evaluate its major competitors. Strengths - Carnival has 75 ships in its fleet and is continuing to brand the company as the ââ¬Å"fun shipsâ⬠- There are large barriers of entry into the cruise businesses. Ships are extremely costly and time consuming to build. - Carnival cruises provide a vacation that includes all activities, food, beverages and transportation to multiple destinations in one low price, appealing the budget friendly cruisers. - Carnival builds it ships specifically for entertainment and fun, the most important factors people are looking for whenâ⬠¦show more contentâ⬠¦With a variety of activities from rock climbing, pools, and casinos, Carnival trips have activities for everyone. Additionally, Carnival recognized the shift in cruise demographics from the start. In the 1970s, cruisers were generally older, however, there was a growing trend of young singles and young families taking cruises. Carnival developed cruises from the start with these new customers in mind. 3. In a succinct manner, state Carnivals value proposition? Carnivalââ¬â¢s value proposition was to be a cheaper alternative to land vacations at all inclusive resorts while providing a variety of activities and destinations in one trip. Carnival was the ââ¬Å"fun shipâ⬠, providing contemporary vacationing to first-time and repeat cruisers. Because customer retention is low, Carnival uses a more traditional style of marketing, focusing on the short-term customer. Each brand under the Carnival umbrella remained independent, especially in respect to sales and marketing. This encourages the sister brands to remain competitive with one another and market their unique value propositions. However, the brands worked together to drive synergies and economies of scale. 4.

Stepping inside, the first thing that hits me is the sound. We will write a custom essay sample on Fast Food Restaurant Description or any similar topic only for you Order Now It crashes over me, engulfing me, drawing me in. I step closer, into the midst of it. To my left sit a young couple, anxiously feeding their toddler chicken nuggets dipped in tomato sauce. The two year old cries and whines, putting his hand up to his mouth as if to say ââ¬Ëno, no more. ââ¬â¢ The group of young people to my right are laughing, shouting and flirting. One of the boys has stolen a girlââ¬â¢s milkshake and she leans across her friends, giggling happily, to try and snatch it back. I can hear the radio playing faintly. The newest, noisiest dance track struggles to be heard in the room full of people, resembling a school canteen. As I make my way upstairs I pass a smartly dressed businessman, holding a brown bag containing a burger, and his other hand to hold his drink. He has his mobile phone trapped between his ear and his shoulder and he jabbers away to his colleague about ââ¬Ëredundanciesââ¬â¢. An elderly woman, accompanied by two young, brightly dressed grandchildren, frowns at the man as she makes her way past, children in tow. The smell of the greasy, fatty burgers is overpowering now, and I can hardly breathe for the stench if freshly cooked French fries. They coat the floor, like a three-inch carpet, soft underfoot. I wonder why these restaurants even bother installing bins ââ¬â nobody seems inclined to use them. Spotting no empty tables, I make my way back downstairs to order my food. I overtake the queue if people waiting for ââ¬Ëveggie-burgersââ¬â¢ and order large fries and a chocolate milkshake. The young girl who serves me canââ¬â¢t be much older than myself, yet she looks older, more tired, world-weary. Her shoulder length hair hangs limp and greasy under her baseball cap, and her red t-shirt is stained with fat and fizzy drinks. The woman next to me has dropped her tray, and someone with a mop rushes to clean up the split cola, before anyone has a chance to fall in it. I smell the air, take a French fry out of the packet, pop it in my mouth and sigh. It tastes like grease, unhealthy and fattening. Looking around me, I decide to find a bench outside and, licking my lips in anticipation of my milkshake, I go in search of one. How to cite Fast Food Restaurant Description, Essays

South By Southwest Essays (779 words) - Mexico, Mexicans
South By Southwest Sociology 105 1. Title : South by Southwest : The Mexican-American and His Heritage 2. Author : John Tebbel and Ram?n E. Ruiz 3. Publisher : Zenith Books and Doubleday & Company Copyright 1969 4. Number of pages : 120 5. The setting of this story covers an immense number of years of conquering and colonization in the Southwest areas we now know as California, Arizona, New Mexico, Texas, and Mexico. It begins in the early 15 and 1600's, in a time when many important Spaniards, such as Juan Bautista de Anza (in 1775 he led the longest overland migration of a colony in North American history before Oregon), were moving into the Southwest in search of gold, silver, bread, and jobs. It also talks about the Indians, who were already living in the area we now know as Mexico, that did not get along real well with the Spaniards(Anglos) when they came in to invade their land. The two main Indian tribes of that time were the Mayas(a peaceful people who were interested in science, invented a calendar to grow maize, and were later believed to be wiped out by a great natural catastrophe), and the Aztecs(a powerful bloodthirsty tribe who feared no human only their gods). Next it went on to the 1800's and early 1 900's, when Mexico decided to fight the Spaniards for their independence. Finally, the book went on into the mid to late 1900's, where Mexico began to modernize and become a good neighbor to the United States. 6. The major conflict was between the Anglos and the Mexicans. It began with the Spaniards and the Indians(Aztecs) fighting over the Valley of Anahuac. The Spaniards(led by Cortez) ended up winning the battle over the Aztecs(led by Moctezuma). Due to the cruel and ruthless Spanish rule, a new social system was set up where the Spanish-born whites were the rulers, the Mexican-born whites were the aristocracy, and the Indians lived lives of poverty and slavery. Another class grew called mestizos(Mexican-Indian), and out of all these were the forces that created Mexico. Next, Mexico(led first by Padre Miguel Hidalgo, then by Jose Maria Morelos, and finally by a traitor D. Augustin de Iturbide) fought the Spaniards for their independence. The first two lost and were killed, but they ignited a spark that later led to victory with the help of Iturbide and his army. For a while Mexico was in chaos, but with the help of many leaders,(Benito Juarez, Porfirio Diaz, and Lazaro Cardenas to name a few) they were able to start making laws and bring Mexico to become a modern society, free from slavery and dictatorship. Now, like the rest of the world, Mexico is developing into an urban area with cities that are modern and spreading out in many directions. 7. I believe the theme of this story to be that although Mexico and the United States had very different histories, they have grown together. They share such a long border that they need to maintain a peaceful border, otherwise many problems can occur. Mexico and U.S. rely on each other for many important imports and exports. In many cases, other than a political one, the line that runs between Brownsville, Texas and San Diego, California is considered an invisible one. Many cross it often, as in some areas it is only a barbed wire fence or a river easily crossed. Also there is said to be about as many Mexican-Americans in the Southwest as there are in the Mexican states just south of the border, which makes it seem, in many ways, as if it is all one region. 8. The main characters were more groups than anything: the Spaniards, the Mexicans, the Indians, and the Anglos, however, there were some important ones' within the groups to be mentioned. These are: Cortez(the leader of the Spaniards when fighting the Aztecs), Moctezuma(the leader of the Aztecs), Padre Miguel Hidalgo, Jose Maria Morelos, and D. Augustin de Iturbide(leaders of Mexico in their revolution against the Spaniards), and Benito Juarez, Porfirio Diaz, and Lazaro Cardenas(all leaders of Mexico helping to organize and modernize Mexico). 9. I would recommend this book to many of my friends and relatives. I have many Mexican American relatives that

Using the Internet for Research, info about EIP Security essays As the economy becomes increasingly technology oriented, and an increasing number of customers begin to use the Internet for reasons other than searching, security becomes an extremely important issue. Customers demand satisfaction and security while transferring sensitive data, such as credit card numbers, and companies wish to provide this security blanket to them. The same problems can exist in the use of enterprise information portals and search engines. These company portals depend on the portals ability to keep sensitive data within its walls, while keeping unwanted users out. The ability of hackers and unwanted visitors to crack EIPs security has led to the affordability of security to plummet. The more sensitive information and data being transferred, the more security is needed. This leads to an increase in the money needed to provide this airtight security. Because of this, the MIS portal team has decided to concentrate on the security issues that currently exist in Enterprise Information Portals. I.

Water Pollution Explained
Water Pollution Explained Water pollution is when water contains contaminants. In the context of environmental science, a contaminant is usually a substance which can be harmful to living things like plants or animals. Environmental contaminants can be the result of human activity, for example a by-product of manufacturing. However, they can also occur naturally, like radioactive isotopes, sediment, or animal waste. Because of how general the concept of pollution is, we can assume that polluted waters have been around even before humans were here. For example, a spring might have high sulfur levels, or a stream with a carcass in it would have been unfit for other animals to drink from. However, the number of polluted streams, rivers, and lakes multiplied rapidly as the human population increased, agricultural practices intensified, and industrial development spread. Important Sources of Pollution A number of human activities lead to water pollution harmful to aquatic life, aesthetics, recreation, and human health. The main sources of pollution can be organized in a few categories:à Land use. We have a heavy impact on the land: we cut forests, plow grasslands, build homes, pave roads. Land use activities intercept the water cycle during precipitation events and snowmelt. As water flows over the land and into streams, it picks up anything small enough to be carried away. Vegetation does an important job of holding back organic and mineral components of the soil, but clearing that vegetation means a lot of substances make it into streams, rivers, wetlands, and lakes, where they become contaminants.Impervious surfaces. Most man-made surfaces cannot absorb water like soil and roots would. Rooftops, parking lots, and paved roads allow rain and snowmelt runoff to flow with great speed and volume, picking up along the way heavy metals, oils, road salt, and other contaminants. The pollutants would otherwise have been absorbed by the soil and vegetation, where they would have been naturally broken down. Instead, they concentrate in runoff water, overwhelming the streamsà ¢â¬â¢ capacity to process them. Agriculture. Common agricultural practices, like exposing soils to the elements, using fertilizers and pesticides, and concentrating livestock, routinely contribute to water pollution. Nutrient runoff, mostly phosphorus and nitrates, leads to algae blooms and other problems. Mismanagement of farm soils and livestock can also lead to significant soil erosion. Soil picked up by rain makes its way into streams where it becomes sediment pollution, with harmful consequences on aquatic life.Mining. Mine tailings are the piles of rock discarded after the valuable portion of the ore has been removed. Tailings can leach to surface and ground waters large amounts of contaminants, some occurring naturally in the waste rocks, others a product of the ore processing methods. Mining by-products are sometimes stored in impoundments as a slurry or sludge (for example, coal ash), and failure of the dams holding back these artificial ponds can lead to environmental disaster. Abandoned coal mines are a notorious source of acid mine drainage: water in flooded mines and in contact with mine tailings sometimes oxidizes sulfur-bearing rocks, and turns extremely acidic. Manufacturing. Industrial activities are a major source of water pollution. In the past, liquid waste was dumped directly into rivers, or put into toxic waste barrels which were then buried somewhere. Those barrels then deteriorated and leaked, resulting in heavily contaminated sites we are still dealing with today. In the United States, regulations now severely limit these practices, notably the 1972 Clean Water Act, the Resource Conservation Recovery Act of 1976, and the Superfund Act of 1980. The release of toxic materials at industrial sites continues, either at levels below regulatory thresholds, or simply illegally. In addition, accidental spills occur all too frequently ââ¬â for example with the recent West Virginia MCHM spill. In developing countries, pollution from industrial sources is still widespread and dangerous to human and ecosystem health.Energy sector. The extraction and transportation of fossil fuels, notably oil, is prone to spills that can have long lasting e ffects on aquatic systems. In addition, coal-fired power plants release large amounts of sulfur dioxide and nitrogen oxides in the air. When those contaminants dissolved in rain water and enter waterways, they significantly acidify rivers and lakes. Coal plants also emit mercury, a very toxic heavy metal, polluting lakes throughout the world and making fish unsafe to eat. The production of electricity through hydropower produces much less pollution, but still has some deleterious effects on aquatic ecosystems. Household practices. There are numerous actions we can take every day to prevent water pollution: avoid lawn pesticides, slow rainwater runoff, collect pet waste, properly dispose of household chemicals and medicine, avoid products with microbeads, attend to oil leaks on the mower or car, have the septic tank maintained and inspected.Thrash. A lot of trash persists in the environment, and plastic matter breaks down into harmful microplastics. Are Contaminants Always a Substance? Not always. For example, nuclear power plants use vast amounts of water to cool down the steam generator by the reactor and used to spin the turbines. The warm water is then released back into the river it was pumped from, creating a warm plume that affects downstream aquatic life.
