...Daisy Bates was born on November 11, 1914 Huttig, Arkansas and was an American Civil Rights Activist, publisher and writer who is best known for her involvement in the struggle to integrate Cental High School in Little Rock, Arkansas. She was an advisor to nine black student trying to attend a previously all white school. She was also an important figure in the seminal moment of the civil rights movement. As a publisher and journalist, she was also a witness and advocate on a larger scale. Bates endured numerous hardships, but in the coming pass years her generous labors on behalf of equality opportunity have earned her many praise. Bates and her husband were important figures in the Little Rock Integration Crisis in 1957. The Bates published a local black newspaper, the Arksansas State Press, which advertised the violations of the Supreme Court's desegration rulings. She guided and advised the nine students, known as Little Rock Nine, when they attempted to enroll in an all white school. Ultimately, the Little Rock Nine were able to attend Central High, and many of them went on to impressive careers. The price for her husband and herself was high, and the advertisers caused the local black newspaper to dry up quickly. It was forced to shut down in 1959. Daisy Bates received many honors and rewards. In 1988 she received the American book award and Honorary Doctor of Laws Degree in the University of Arksansas, 1984.

New Madrid Earthquake

...New Madrid, MO Earthquake of 1811-1812 Janelle E Kizer Geology 101 Spring 2012 1. Introduction: During 1811 – 1812, four earthquakes occurred in New Madrid, Mississippi River Valley, which are considered to be some of the most humongous earthquakes in the U.S. since the settlement by the Europeans. The first two was at 1811, December 16, Northeast Arkansas, Magnitude 7.2-8.1. The next one was at January 23, 1812 right at New Madrid, Missouri and the magnitude was 7-7.8. The last one occurred at February 7 of 1812, 9:45 Coordinated Universal Time (UTC), in New Madrid, Missouri with a magnitude 7.4-8.0. All these earthquakes were 3 times stronger than the Alaska earthquake of 1964, and 10 times stronger compared to the San Francisco earthquake of 1906. 2. Geographic location of New Madrid, MO: New Madrid was formed in 1808. It is situated on the Mississippi River and interstate 55. It has a population of 3154 residents, and it is considered as a small community in United States. New Madrid, MO is located at 36.59° North latitude, 89.53° West longitude and about 89 meters altitude above the sea level. Geographic coordinates: Latitude: 36.59° North Longitude: 89.53° West Altitude: 89 m [pic] 3.

Himalayans

...Instability in the Himalayas: Earthquake in Nepal All life is at the mercy of nature. Whether it feeds and nurtures a species, or drives it to extinction, all life on earth is controlled by the forces of the natural world. There are many examples of the violent and catastrophic effects of natural disasters, but perhaps none is more relevant to the present than earthquakes. There are “only about 15 earthquakes a year in the world — out of 1.3 million total temblors — are magnitude-7.0 or higher, according to the U.S. Geological Survey. The devastating earthquake and resulting tsunami that hit parts of Japan in 2011, killing thousands of people, was magnitude-9.0” (geologyin). On the 25th of April, 2015, an earthquake of a magnitude of 7.8 by the Richter scale struck Nepal, leading to thousands of casualties and leaving the country in a state of emergency. Although the immediate effect of the earthquake was the loss of many human lives, the geology of the Himalayas was also strongly affected. Earthquakes are such powerful agents of natural disaster, they not only re-shape the biotic factors of a region, but they also re-shape the abiotic factors of its impacted area. Nepal is a small country located north of India and south of China. Its topography ranges from lowlands in the south, and hilly and mountainous regions in the north. The climate is just as varied and ranges from tropical to alpine (Bradford). Its size is relatively similar to Arkansas, about 56,827 square miles...

Earthquake Danger in Midwest

...“Earthquake Danger in the Midwest” Kaplan University SC300-13 July 1, 2011 The United States Geological Society (2011) states “The world’s earthquakes are not randomly distributed over the earth’s surface, and tend to be concentrated in narrow zones”. This statement seems to hold true when it comes to the distribution of earthquakes in the United States as they happen primarily in those narrow fault zones. These fault zones are located in Alaska (Prince William Sound), on our West Coast ( San Andreas Fault), on our East Coast (Rambo Fault Line) and in the Midwest (New Madrid Fault) which all lying on the North American Tectonic Plate, a massive irregularly shaped slab of solid rock which is approximately 8000 kilometers or almost 5000 miles wide (Trefil and Hazen, 2011). Tectonic plates are in constant motion as they interact along their margins to form mountain belts, earthquakes and volcanoes. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest. Living in Cincinnati, Ohio carries a relatively high risk of a major earthquake because it lies on the border of the New Madrid Seismic Zone (NMSZ) and the Wabash Valley Seismic Zone (WVSZ) which have the most active geological areas in the eastern United States. The smaller of the two areas is the Wabash Valley area which lies in the Southeastern part of Illinois and Southwestern part of Indiana and came...

Dangerous and Natural Energy Earthquakes

...Prof: Tanya Crail What’s a earthquake? According to the Geology Labs on-line website an earthquake is the sudden release of stored energy, caused by the shifting of tectonic plates. The energy release is a shock wave or seismic wave. The seismic wave is what causes the ground to move or shake, when this occurs we have a earthquake. According to the 2008 United States National Seismic Hazard Maps a lot of the west coast as far south as Hawaii, and north to Alaska has a lot of earthquake activity. The Pacific “Ring of Fire” (named for the large amount of active volcanoes), has a lot of tectonic activity. Tectonic plates are large plates of rock that make up the foundation of the Earth's crust and the shape of the continents. Question: What patterns do you see in the distribution of earthquakes across the continental United States? Answer: Earthquakes occur on fault lines, a location where tectonic plates have collided together and shifted or are sliding past each other. The size of the earthquake depends on how much slide or shift occurred. Most fault lines are located in costal areas, because of the continental and oceanic plates colliding together. Most of the United States earthquakes occurs on the west coast. California, and the entire west coast including Hawaii, and Alaska have the highest hazard rating at 64+, central locations of the United States like Texas, North and South Dakota seem to have the lowest risk of earthquakes, however Missouri, Illinois, Indiana...

New Madrid Earthquakes

...Boulder, CO, USA - This new volume from The Geological Society of America presents the geologic history of the central Mississippi River Valley and the surrounding area from Precambrian through Holocene times. Its focal point is the New Madrid seismic zone that both threatens and intrigues. Written to engage a wide range of geologists, from beginners to those thinking of conducting research in the Mississippi River Valley, the book's conversational style makes it a pleasure to read. The book begins with a brief presentation of the geologic history of the southeastern United States, and subsequent chapters expand upon particular periods of time, discussing the most important regional geologic events and how those events affected the central Mississippi River Valley. The concluding chapters discuss the geology and seismology of the New Madrid seismic zone, updating readers on Mississippi Valley's past earthquakes. Author Roy Van Arsdale's (Univ. of Memphis) engaging style is readily evident in this sample from the book’s preface: Have you traveled along Interstate 40 between Memphis, Tennessee, and Little Rock, Arkansas? Do you remember the trip, or did you put your car on cruise control and catch some shuteye? Unless you find cotton, rice, or bean fields exciting, this is a flat, boring, landscape today. Except for the small rise at Crowley’s Ridge, you are traversing the central Mississippi River Valley for nearly 150 km. It wasn't always so placid and dull. Park...

Comparison of the Christian Identity Movement and Sovereign Citizens

...the world and the second coming of Christ will occur in the near future. During this time, Jews will utilize their influence to wage war against the white race. Some Christian Identity Movement followers have interpreted Biblical scripture to mean that they have been chosen by God to watch for the signs of this impending war, and to prepare themselves and others to fight for the cause of Christ. Biblical scripture points to numerous signs that will signal the coming end of times. Some of these include an increase in natural disasters such as hurricanes, famines and Christians being killed for practicing their religion. (2) The fact that we regularly see earthquakes and hurricanes has given the Christian Identity Movement followers, proof (in their eyes) that the end of times is near. If we look throughout history, weather tends to run in cycles and more intense and frequent natural disasters may occur in one year, as opposed to other years. Even with this knowledge, Christian Identity Movement followers continue to distort Biblical teachings to rationalize their distorted view of minorities and the world in general.

Geology

...Physical Geology: Term Paper The break that now separates the Ouachita Mountains from the Appalachians, a feature known as the Mississippi Embayment, constitutes one of the largest and least understood landforms of the central U.S. In the article, “The Mississippi’s Curious Origins” the authors, Roy B. Van Arsdale and Randel T. Cox shed light on the mysterious Mississippi Embayment. They begin by explaining the origins of the horseshoe-shaped lowland that is underlain by massive quantities of sand, silt and mud deposits. They begin at what geologist call Pangea, which is when North America, South America, Africa and Eurasia came together to form one supercontinent. This collision raised several mountain ranges, including the Ouachita-Appalachian. Pangea is said to be ripped apart where it had previously been sutured together: just outside the arc of the Ouachita-Appalachian Mountains. This opening formed both the Atlantic Ocean and the Gulf of Mexico. This article then states that for a long period of time the Gulf Coast remained geologically stable, with no continents plowing into it or rifting away. The northern coast of the Gulf Coast began to warp upward over a large area; this is the footprint of what is now the Mississippi Embayment. As the very large arch that formed up to three kilometers high and then subsided just as much below sea level, what had been the crest of a high, arched mountain range became inundated with seawater and was eventually buried by as...

New Madrid 1811-1812

...New Madrid(1811-1812) In the autumn of 1811, the United States was barely 35 years old. The fledgling nation included only 17 states, all east of the Mississippi River, but it boasted a lot of new territory thanks to the Louisiana Purchase of 1803. Neither the buyers nor the sellers knew that the recent addition's basement contained a seismic time bomb nearly ready to go off At around 2:15 a.m. on December 16, 1811, a series of massive earthquake pummeled what is now southeastern Missouri and northeastern Arkansas with ground motions so strong that trees snapped in two as they whipped back and forth. The landscape rose several meters in some areas and sank in others, changing the courses of creeks and waterways. During one of the quakes, even the mighty Mississippi was diverted; portions near the quake's presumed epicenter flowed backward for at least several hours, and possibly a day or more. People felt the temblor as far away as New York state, and seismic vibes from an aftershock that struck at dawn traveled almost as far, reaching residents in Georgia and what would soon become the state of Louisiana. Another quake of a similar size , maybe an aftershock, or maybe a separate quake along a different portion of the same fault zone - rumbled on January 23, 1812. The final major shaking in the series came about two weeks later, on February 7, when spreading seismic waves flung books from their shelves in Charleston, S.C., and rattled cups and saucers in Washington, D.C.

Energy

...Natural Energy Earthquakes in the World Today Kaplan University SSD300-03 Professor Derby July 4, 2010 Natural Energy 1 Where do earthquakes come from? Below the earth’s surface in a region called hypocenter, this is where the initial activity begins. Moreover, triggers the fault plane to slip where two pieces of earth past one another forming an earthquake generally, certain geographical areas of the country are more prone to this type of activity. History has revealed to us that the San Fernando region in California has been greatly affected by seismic activity over the years. We can view the danger levels from the National Seismic Hazard maps that give us a good depiction of the activity there. The San Fernando fault which it’s commonly known to be in the red zone (very high risk). Unlike, this high level risk region other states bordering California such as Oregon, Nevada and Arizona fall on the scale of yellow, green and tan. Signifying that there is less seismic activity in these states these are a few of the patterns on the west coast. However, moving more to the central region of the country we see some similarities from the west coast. In states such as Tennessee, Arkansas and Missouri where their color scale ranges from green, yellow, tan to red (very high risk). As we can see not only is California prone to being high risk for seismic activity, but other states as well. Growing up in Long Beach, California for a period of time I remembered...

Map I shows where the county lines are located within Tennessee. You can also see where Memphis is located within the county. Map II shows the elevation levels of the state. As you can see in that map, Memphis is located within the lowest elevation levels of the state. Map III shows the rivers that run throughout the state. The main river that runs between the Tennessee, Arkansas, and Missouri borders is the Mississippi River. There are several natural disasters that I would consider to be threats to the Memphis area. One natural disaster that I would consider to be a concern to Memphis would be an earthquake. According to the United States Geological Survey, (USGS), there is an approximately six percent chance that there will be a major earthquake within 50 kilometers of Memphis in the next 50 years (Homefacts.com)....

...Deep Impact: Fracturing Planet Earth for Clean Energy Deep Impact: Fracturing Planet Earth for Clean Energy 1 Name University WGU Student ID# Deep Impact: Fracturing Planet Earth for Clean Energy 2 Shale gas has been acclaimed as the solution for a clean energy alternative. It burns cleaner than both coal and oil. There are vast quantities located in several shale formations domestically, in the United States (U.S.). Natural gas is an odorless, colorless hydrocarbon composed mostly of methane found deep in the earth in formations known as shale. In mid-1997, George Mitchell, an independent prospector made a discovery that would change the natural gas exploration industry for the twenty-first century. (Hinton, 2012). The modification of the well completion technology known as hydraulic fracturing (fracking) and horizontal drilling allowed the oil and gas industry the ability to tap into natural gas reserves trapped in shale deposits miles beneath the earths’ surface. (Hinton, 2012). Mitchell found that forcing fracking fluid at extremely high pressure into the shale formations created fissures in surrounding rock releasing the hydrocarbons and capturing them in the well head. The fracking fluid, also referred to as slick water, is made up of water, chemicals, and sand. Heywood (2012) reports that members of the energy and commerce committee of the U.S. House of Representatives said that between 2005 and 2009 the oil and gas service companies were using over 2,500...

...1-Wal-Mart history and Introduction The first Wal-Mart was opened in Rogers, Arkansas, in 1962. By 1969 it was incorporated into Wal-Mart Stores, Inc., and in 1972 went public on the New York Stock Exchange. The company grew steadily across the United States, and by 1990 was the nation's largest retailer. In 1991 and 1994, Wal-Mart moved into Mexico and Canada respectively. By 1997 it was incorporated into the Dow Jones Industrial Average. As of 2005, Wal-Mart has stores in the United Kingdom, and Puerto Rico, and brings in revenue of close to 300 billion dollars a year. In 2006, Wal-Mart invaded the China and India's markets. During the last two decades, Wal-Mart has been able to take advantage of the rise of information technology and the explosion of the global economy to change the balance of power in the business world (Wikipedia, 2006). Today Wal-Mart continues to grow and their success is not only from their sound strategic management planning but also from its implementation of those strategic plans. In other words operational planning has been an important key to their success.  2-Wal-Mart Strategy Once plans have been developed, an organization must address how management will be accomplishing be those plans. This involves operational plans that must flow from strategy; specify resource, time issues, and commitment of human resources. Operational plans at the lower - levels of the organization, have a shorter time horizon, and are narrower in scope (Bateman...
