HIV is a virus that most of you, if not all, have heard of. That is because over 1.2 million Americans live with it everyday. Many of you may wonder: what makes this disease so dangerous? Well, out of all these infected people, one in eight are not even aware that this virus is currently multiplying in their bloodstream (CDC). This ignorance stems from the fact that HIV initially lies latent in the body for up to ten years. After this period, it becomes a sneaky killer by destroying the white blood cells of the immune system. When your body no longer has a†¦show more content†¦It is a virus that desecrates immune systems and can slowly creep upon its victim due to its potential ten year incubation period. You might contract the disease and not even know it. The virus kills by destroying all your disease fighting T cells, leaving your body powerless to foreign pathogens that we are surrounded by everyday. b. HIV is an incurable disease that relies on coreceptors to initiate host cell interaction and proliferates by utilizing the host cell’s own machinery to reproduce new virus. We will more deeply explore the mechanism in which HIV virions infiltrate and deceive our host cell. In addition, we will discuss current treatment and research that are in the process of finding a highly coveted cure. 3. Disease Description: low level i. HIV is a virus that kills cells in our immune system, which protects us from germs and sickness. When we lose our primary method of infection defense, our body can no longer fight illness and we can die. It originally came from chimpanzees in Africa who had the same disease in monkey form. Humans hunted them for meat. When these people killed them, contacted the chimpanzee blood, and ingested the infected meat, they allowed the monkey form of the virus to enter their bodies (The AIDS Institute). Viruses are strong because they can change in order to survive. ï ¿ ¼Therefore, the virus changed so that it could live in human cells, which led to the birth of

Fertility, Family Planning and Income - 1202 Words

Fertility is one of the main issues discussed when talking about the demography of the United States. The U.S. economy plays a rather large role in the rising and falling patterns of the country’s fertility rate. In many past occurrences of economic hardship in the country fertility levels had decreased. One of the main reasons for that being in times of financial struggle, men and women are less likely to want to have children. Being able to support a family is already a difficult task but when people are getting laid off from jobs, unemployment rates are increasing, and the economy is struggling many people can barely afford to buy necessities for themselves never mind for an entire family. An extended decrease in fertility levels could†¦show more content†¦The remaining four articles are scholarly, peer-reviewed articles that I found related to my topic. The article â€Å"The Economic Explanation of Fertility Changes in the United States† from volume 25 of P opulation Studies was published by Alan Sweezy. This was a very informative article about the most common explanation of fertility changes. That being when the economy is stable, fertility will be high, and when it is not, fertility will be low. This article is useful to my paper because of how it relates economical factors to the issue of fertility. The author includes charts relating the total fertility rate to the gnp per capita using information from the U.S. Bureau of the Consensus. This provides me with more concrete evidence and the numbers to show that the economy does in fact alter the rate of fertility in the United States. My second article was from the chapter on Human Capital, Fertility, and Economic Growth from â€Å"Human Capital: A Theoretical and Empirical Analysis with Special Reference to Education (3rd Edition)† written by Gary S. Becker. The author makes some good points about how human capital, fertility, and economic growth are all intertwined and he provides very detailed charts and formulas to prove his thesis. I thought his research was useful in proving my own thesis that fertility rates are influenced in some way by the economy of a country.

Tiered Lesson Plan Free Essays

Differentiated instruction is a concept that has gained in popularity over the past few years. The goal of differentiated instruction is to maximize learning success for all students. This type of instruction provides a variety of different ways for students to take in information and make sense of ideas (Hall, 2002). We will write a custom essay sample on Tiered Lesson Plan or any similar topic only for you Order Now The expectation associated with differentiated instruction is that a teacher is willing to make certain modifications in order to ensure learning participation by all students (Hall, 2002). Each student learns in a different way and in order to make sure that all students meet educational objectives differentiated instruction uses a combination of whole group, small group and individual instruction in order to meet the learning needs of all students (Hall, 2002). In addition, differentiated instruction recognizes that all students have different background knowledge, readiness, language, preferences in learning and interests. Recognizing these differences allows all students, regardless of academic ability, the chance to succeed in school. Unfortunately, society has a negative attitude about those with learning disabilities (Carolan Guinn, 2007). However, it is essential that teachers are able to modify lesson and curriculum in order to meet the learning needs of all students. Teachers cannot have abelist attitudes towards their students. They cannot expect them to do things they are not able to do (Carolan Guinn, 2007). Therefore, this lesson aims to â€Å"minimize the impact of disability and maximize the opportunities for students with disabilities to participate in schooling and the community† (Carolan Guinn, 2007). The lesson calls for each student to write a report about a farm animal. Modifications about length, number of sentences and spelling requirements can be made for struggling writers in Tier I performing below grade level. A visit to a local farm has allowed all students the chance to see animals in their natural habitat to find out what they eat, what their offspring are called and what resource their animal provides for humans. In order to encourage struggling writers to include all of this information they could write a list instead of whole sentences. In addition, they could include illustrations to help them get their point across. The idea behind the standard (Students use writing as a tool for learning, inquiry, and research) is that students get the opportunity to practice their writing skills. For a struggling writer, simply writing a few words would meet that objective. In addition, students are also required to write a letter to their animal. For struggling writers this could include just one sentence and a picture. Another option would be to have students glue a picture of their animal to a piece of paper and thank their animal for what it provides to humans. Tier II includes students learning at grade level. These students must complete the objective according to grade level so they will be required to include three complete sentences in their letter to their animal. They will also include information about their day in their letter. These students will be expected to use proper capitalization and punctuation as well. Tier III includes students performing above grade level. Often these students are not challenged enough in the classroom so certain modifications need to be made to ensure that they are learning. To this end, these students can write a complete story about their trip to the farm including a beginning, middle and end. They could also create a poster telling why their animal is the best animal on the farm. These activities, in addition to required assignments, will provide high achieving students with the chance to further their writing skills through extended activities. In order to best serve each student they must be placed in the appropriate tier. Students of the same age are not all alike when it comes to learning (Tomlinson, 2001). Therefore, careful consideration must be made when choosing the best tier for each student. In differentiated instruction, commonalities among students are noted but differences are also addressed as well (Tomlinson, 2001). Realizing the differences is what allows a teacher to maximize educational success for all students regardless of ability level. Each tier allows students to process and internalize information based on their specific skill level (Tomlinson, 2001). This type of division promotes classroom learning by all students. Students will be placed in tiers based on their writing abilities. Students who struggle to write complete sentences, form individual letters or incorporate capitalization and punctuation will be placed in Tier I. These students will enhance their skill level in these areas by focusing on fewer sentences but more time spent on creating a correct sentence. Students who are performing at grade level based on writing skills will be placed in Tier II. These students will display the ability to write complete sentences using capitalization and punctuation and will also be able to write legibly in order to get their point across. Finally, students who are performing above grade level will be placed in Tier III. These students will show remarkable ability to quickly write more than three complete and correct sentences. They will show higher levels of thinking in their writing. The lesson will be considered successful when all students have correct written work to show for their time. Regardless of ability level, all students will write, based on their individual skills, correct sentences. Tier I students will write one complete and correct sentence that shows improvement in capitalization and punctuation just as Tier II students will write three sentences. Tier III students will show higher levels of learning through writing using paragraphs. It doesn’t matter how many sentences each student writes, but it does matter if they can show what they have learned about farm animals through the writing of clear and concise sentences. Grades will be given based on the final product but the most important assessment of student learning is the growth a teacher is able to see from each student (Tomlinson, 2001). .mce-content-body .mce-resizehandle.wildfire-hover { background: rgb(0, 0, 0); }; .mce-content-body [contenteditable="false"] [contenteditable="true"].wildfire-hover { outline: rgb(122, 202, 255) solid 2px; }; .mce-content-body img.wp-media.wildfire-hover { background-color: rgb(237, 237, 237); border-color: rgb(114, 119, 124); };a[data-wplink-url-error], a[data-wplink-url-error].wildfire-hover, a[data-wplink-url-error]:focus { outline: rgb(220, 50, 50) dotted 2px; position: relative; }; How to cite Tiered Lesson Plan, Papers
