Should I Earn a Real Estate Degree

A real estate degree is a postsecondary degree awarded to students who have completed a college, university, or business school program with a focus on real estate. Although programs can vary by school and specialization, most students earning a degree in real estate study business, real estate markets and economies, residential real estate, commercial real estate, and real estate law.   Types of Real Estate Degrees There are four basic types of real estate degrees that can be earned from a postsecondary institution. The degree you can earn depends on your education level and career goals Associates Degree - Typically a two-year program; designed for students with a high school diploma.Bachelors Degree - Typically a four-year program, but accelerated programs are available; designed for students with a diploma or an associates degree.Masters Degree - Typically a two-year program, but accelerated programs are available; designed for students who have already earned a bachelors degree.Doctorate Degree - Program length varies depending on the school; designed for students who have already earned a masters degree. Choosing a Real Estate Degree Program There are a growing number of colleges and universities offering associates and bachelors degree programs with a focus on real estate. You can also find masters and MBA level programs at a number of business schools around the world. If you are interested in attending a real estate degree program, you should choose a program that is in line with your academic needs and career goals. It is also important to find a program that is accredited. Other Real Estate Education Options A degree in real estate is not always required to work in the real estate field. Some positions, such as real estate clerk and property manager, require little more than a high school diploma or the equivalent, though some employers do prefer candidates with at least an associates degree or a bachelors degree. A high school diploma is also the basic starting requirement for real estate agents, who also need at least a few hours of real estate courses in addition to a diploma before they can be licensed. Students who are interested in receiving a formal education in real estate, but do not want to take a degree program, can consider enrolling in a diploma or certificate program. The latter two programs are typically very focused and can normally be completed much faster than a traditional degree program. Some organizations and education institutions offer single classes that can be taken to prepare for a real estate license or a specific position in the real estate field. What Can I Do With a Real Estate Degree? There are many different careers open to students who have earned a real estate degree. Obviously, many go on to work in the real estate field. Some of the most common job titles include: Real Estate Clerk - Real estate clerks perform many of the same duties as a general office clerk. They may be responsible for administrative tasks, such as answering the telephone, handling the mail, making copies, sending faxes, typing letters, filing, and arranging appointments. They may also interact with real estate clients and assist agents and brokers with day-to-day duties. Real estate clerks generally need a high school diploma or the equivalent. However, some employers prefer candidates with an associates or bachelors degree.Property Manager - Property managers, or real estate managers as they are sometimes known, are responsible for caring for a property. They may be in charge of maintenance, upholding real estate value, of handling interactions with residents. Some property managers specialize in either residential or commercial property. A high school diploma may be enough for some positions. However, many employers prefer to hire candidates with a bachelors or masters de gree.Real Estate Appraiser - Real estate appraisers estimate the actual value of a property. They may specialize in commercial or residential real estate. Education requirements for appraisers vary by state. Some states require at least an associates degree, but a bachelors degree is more common.Real Estate Assessor - Real estate assessors estimate the value of properties for taxing purposes. They typically work for local governments and appraise entire neighborhoods rather than select properties. Education requirements for assessors can vary by state or locality; some assessors have only a high school diploma, while others are required to have a set degree or licensing.Real Estate Agent - Real estate agents have many different duties, but their primary responsibility is to help clients buy, sell, or rent homes. Real estate agents must work with a broker. They need to complete at least a high school diploma or the equivalent as well as some college courses in real estate or accredit ed pre-licensing courses to earn the required licensure.Real Estate Broker - Unlike real estate agents, real estate brokers are licensed to manage their own business. They may help clients buy, sell, rent, or manage real estate. They may specialize in residential or commercial real estate. Real estate brokers need to complete at least a high school diploma or the equivalent as well as some college courses in real estate or accredited pre-licensing courses to earn the required licensure.

Oak is the Official U.S. National Tree

The mighty oak tree was  voted  the United States favorite tree in a National Arbor Day Foundation poll taken in 2001.  Nearly five years later, a  Congressional passage and a presidential signing of a historic bill made it the official  national tree of the United States in late 2004. Americas national tree is the mighty oak. The Congressional Passage of the Official National Tree Having oak as our national tree is in keeping with the wishes of the hundreds of thousands of people who helped choose this striking symbol of our nation’s great strength, said John Rosenow, the  president of The National Arbor Day Foundation. The oak was selected during a four-month-long open voting process hosted by the Arbor Day Foundation. From the first day of voting, oak was the people’s clear choice, finishing with more than 101,000 votes, compared to almost 81,000 for the magnificent runner-up, the redwood. Rounding out the top five were the dogwood, maple, and pine. The Voting Process People were invited to vote for one of 21 candidate trees, based on broad tree categories (general) that included the state trees of all 50 states and the District of Columbia. Each voter also had the option to write in any other tree selection they preferred. Advocates of the oak praised its diversity, with more than 60 species growing in the United States, making oaks America’s most widespread hardwood tree. There is an oak species that grows naturally in nearly every state in the continental U.S.   Why Oak Trees Are so Important Individual oaks have long played a part in many important American historical events, from Abraham Lincoln’s use of the Salt River Ford Oak as a marker in crossing a river near Homer, Illinois, to Andrew Jackson taking shelter under Louisiana’s Sunnybrook Oaks on his way to the Battle of New Orleans. In the annals of military history, Old Ironsides, the USS Constitution, took its nickname from the strength of its live oak hull, famous for repelling British cannonballs. Uses for oak tree wood are of major importance and in high demand as a commercially harvested tree species. Oak has an extremely dense wood and resists insects and fungal attacks because of its high tannic acid content. It saws even and true with beautiful grain desired for building the best furniture and cabinets along with the durability necessary for fine flooring. It is a perfect wood for long-lasting timbers for building, perfect planking for shipbuilding and the barrel staves used for storing and aging fine whiskey spirits.

Inequality and Constitution Essay - 2599 Words

Liberty, as defined by the Oxford dictionary, is explained as the â€Å"condition of being free from restriction or control; the right and power to act, believe or express oneself in a manner of one’s own choosing†. Liberty is a word familiar to most Americans, since the fundamentals of the country is based on freedom and independence. Symbolism of liberty (such as the national’s flag, statue of liberty, the liberty bell, Uncle Sam, the bald eagle) can be seen throughout the United States as a reminder of the freedom in which this nation has achieved for over the past two hundred years. Perhaps one of the greatest achievement of liberty by the Americans in the past two hundred years has been the founding of the United States Constitution.†¦show more content†¦Although federal armed force were sent to cease the rebellion, but the rebellion had already challenged and undermined the authority of the individual states, proving how necessary it is for them to form a stronger government. Since the Article of Confederation allowed independence to each state, there was no main authority that binds the states together as one to solve national problems. It is then, when George Washington and Alexander Hamilton began writing the new constitution, in hopes to form a stable unified national government. The Constitution is without a doubt, the backbone of the United States. It sets forth fundamentals of governments, rights, and freedom. With such a sacred document that such a powerful nation today still follows, the constitution seems flawless as it has been successfully been the main influence in American politics, then, and now. Since the constitution provided liberty and rights for all individuals, then why does inequality and racial discrimination still exist today even after the constitution has been established? The constitution is supposed to provide every individual with their rights and freedom, but yet, the constitution itself has flaws in its content for freedom and equality.

Nano-Composites

Question: Describe about Nano-composites. Answer: Introduction to Nano-composites In the field of nanotechnology there are various things which are yet unknown or are still in the development phase. The NANCOMPOSITES is also a topic which is still under research and development phase. Nanocomposites are those composites which have the dimension in the nanometric range. Although the preparation process of nanocomposites is difficult to control, yet the importance of it cannot be overlooked. The nanocomposites have provided a great alternative to the monolithic and microcomposites. It is considered that when a particle is made into a size which is known as critical size of that material then it changes the parental properties. This is because as the size decreases the property of interaction at different phases changes and so does the property of the material. In the recent past, various nanocomposites such as carbon nanotubes and polyester have been discovered possessing excellent mechanical, thermal and electric properties which added a new dimension to the field of nanotechnology (Schmidt, 2012). The main advantage of the nanocomposites is that they are environment friendly beside it offers new technology and development day by day. The nano-composites are broadly classified into three groups, and they are as follows: Polymer Matrix Nanocomposites Metal Matrix Nanocomposites Ceramic Matrix Nanocomposites Properties The Nanocomposites possess some amazing properties which can be found in the larger sized or parental components. The properties which the nanocomposites possess are mechanical toughness, chemical stability, high thermal stability and good wear resistance (Gleiter, 2012). However, it also comes to the low toughness of ceramics which have been considered as a stumbling block when it comes to the wider use of nanocomposites in the industry. This limitation of nanocomposites have been overcome by the ceramic matrix nanocomposites which posses higher mechanical properties. The nanocomposites have high strength when we consider either the compressive force or the tension force. Furthermore, the more and more mixing of several materials, the wider the scope of the nano technology becomes (Roy, 2013). Different approaches are followed to find out a new composite which have some unique electrical, mechanical, magnetic, catalytic and optical properties. They have the potential to find out the applications in the field of aerospace and automobile industries. The metal matrix composites and the ceramic matrix nanocomposites shows great challenge to be used in the aerospace and automobile industry, but when it comes to real success, its brings some difficulties. The nanocomposites doesnt have only the advantages to be discussed about, rather it has some disadvantages too, which needs to be discussed. It has some fairly low strength of modulus when it is compared to the ceramic and the metal (Braun, 2011). Conclusion Considering the fact that as the year passes by, researcher are in a search of finding more and more newer technologies which could take over the conventional process of living. The nanocomposite shows the perfect promise to deliver the same and gives an edge to the scientists and researcher working on newer material which posses different properties from their parent.
