Free States V Slave States Essay

There have always been events in American history that increased tensions between free states and slave states. In the following essay I will go over three events that has caused problems between one other. The Compromise of 1850, Uncle Toms Cabin, and John Brown’s Raid at Harper’s Ferry I have chosen these events because these are the events that stand out to me when tensions between free states and slave states come to mind. The Compromise of 1850 included four laws. California entered the union as a free state. A stricter Fugitive Slave Law requires that escaped slaves be returned. Slave trade prohibited in Washington D. C. Popular Sovereignty vote of the people living in the territory. Uncle Tom’s Cabin by Harriet Beecher Stowe was the best selling book of the nineteenth century. This book caused many to oppose slavery. This showed Americans what slavery has done and this book opened up northern eyes against slavery. This caused the Southern to be outraged because now they have to deal with all the negative northern remarks. The last event is John Brown’s Raid at Harper’s Ferry. In 1859 John Brown led a small group against a federal arsenal. His plan was to seize the weapons and lead a slave uprising. Even though he was unsuccessful and was also executed he became a Northern hero. This incident increased the distrust that was already between the Southern and the North. In conclusion The Compromise of 1850, Uncle Tom’s Cabin, and John Brown’s Raid at Harper’s Ferry are events that rose tensions between free states and slave states. The compromise of 1850 pleased no one. It cause northern in civil disobedience against the Fugitive Slave Law by protesting and helping slaves to reach the safety of Canada. Uncles Tom’s cabin single handedly opened up peoples mind against slavery. This made people realize how horrible it is to take another mans freedom this caused problems for the slave states because now the free states wanted to get rid of slavery once and for all. John browns attack proved to the northerners anyone can make a difference if they believe slavery is wrong. This also increased Southern distrust of the North. These are the three events that stood out to me there are a lot more but these are the greatest disputes that effected North and South.

Let’s Be Lefties for a Day

â€Å"The perception of normality is based on how closely you resemble the majority of people† (Devry College, 2013, Week One Assignment, Para. 1). I have been right handed since 2nd grade. This was not always the case though. When I began Kindergarten in 1985, I was predominantly left handed. I was persistently discouraged from writing with my left hand and eventually I became fluent in penmanship with my right hand. At the time, I recall being told that â€Å"Everyone should write with their right hand!† I was taught early on, that to be normal is to be like everyone else. To this day I am still right handed as far as for writing, however, I have always favored my left hand for activities such as gymnastics and driving. I remember feeling weird and looked down upon for being different and for taking longer than my classmates to learn how to write with a hand that felt foreign to me. Did it pay off? Was there an advantage to being right handed versus left? These are qu estions that are not as black and white as they may seem.This paper examines normalcy and what it means to be a part of the majority versus being a minority. In our society, right-handed people reflect the majority or dominant group and left-handed individuals would be considered the minority based on the percentage of right versus left-handed people. In order to understand the affects of being in a minority group, we were challenged to â€Å"Let’s be lefties for a day. † It was quickly apparent that our society and environment is catered toward right-handed people.This reflects a principle known as institutionalized discrimination where minority groups are at a disadvantage because of the normal way society operates (Devry College, 2012, Week One Lecture, para. 2). Take buttons for instance. It is much easier to button jackets, or pants, etc†¦ with one’s right hand as opposed to one’s left. The reason for this is simply that the vast majority of mec hanisms for buttoning, or zippering, are adapted for ease of right-handed individuals. Another example is door knobs. Most door knobs are manufactured with right-handed ergonomics in mind.Opening doors with my left hand involved twisting my wrist in a manner that is both awkward and uncomfortable. Further exploration found that items such as golf clubs, scissors, kitchen utensils, and keyboards, are available for left-handed individuals; however, they come at a price. Not only were they more expensive per unit than â€Å"standard† items that are readily available; but they also required internet access as they are primarily found online, and included shipping fees in addition to the already hefty price tag.It was evident that in this instance, being in the minority or less dominant group incurs inconvenience and monetary penalty. â€Å"Through these major institutions, the dominant group will shape the society in ways that reflect its interests, values, and beliefs and minim ize those of less dominant groups. The result is discrimination† (Devry College, 2013, Week One Lecture, Para. 2). Having spent the majority of my life right-handed, I hadn’t given much thought to what it means to be left-handed.It is easy to not have to consider what life is like for those in the less dominant groups when things as simple as the ease of opening a door, or a can, or sharpening a pencil, and/or buttoning ones pants do not require a second thought. Devry College, 2013, Week One Lecture states that â€Å"[u]nlike the dominant group, most minority groups recognize and understand cultural differences. Unfortunately, they also feel the need to be wary and defensive at all times† (Para. 8). This is very similar to how I felt almost 30 years ago when I took my first penmanship class in Kindergarten and was instructed to become a rightie versus a leftie.The Devry College, 2013, Week One Lecture continues â€Å"[t]he end result is that subordinate groups always know and understand more about the dominant group than the dominant group does about the subordinate group† (Para. 8). It is important to recognize that we all have differences, be it cultural, ethnic, gender, or something as seemingly simple as being right or left-handed. These differences are what creates diversity and adds richness and color to our world and â€Å"†¦is a major component in the social glue holding a culture together.What we want to do is simply recognize that we do have prejudices arising from our ethnocentric view of the world† (Devry College, 2013, Week One Lecture, Para. 10). There is an old familiar saying that you never know a man till you have walked a mile in his shoes. This is so true and it can be easy to forget that beyond our obvious differences, we are all human. How does all of this relate to the business setting? M. Bell, 2012 states that â€Å"[i]n inclusive organizational cultures, employees feel as though they are accepte d, belong, and are able to contribute to decision-making processes† (M.  Bell, 2012, p. 5).Imagine all of the important discoveries, policies, and practices that would not exist if we had not recognized the contributions of minority members of our society! That said, there is still a long way to go. Individuals need to be recognized and considered for their qualifications when seeking employment or promotion, not discriminated due to their gender, ethnicity, or cultural differences. In conclusion, the leftie experiment was a real eye-opener! I never realized how difficult seemingly simple things can be for some, and how much I take for grantedThe world is a different place for minorities and we need to level the playing field through acceptance and understanding. Ethnocentricity is not always a bad thing. It is the tie that binds us; but when used to discriminate, it serves only to tear us apart. How do we move forward? Devry College, 2013, Week One Lecture declares that hon esty and â€Å"explaining all options and services available† are key to braking down the barriers between majority and minority groups created by distrust (para. 11).

Chernobyl Informative Speech

Attention Getter: There are currently 442 active nuclear power reactors worldwide according to the Nuclear Energy Institute. Of all of the reactors worldwide, 14 have been classified as accidents where the public has been exposed to radiation. The most devastating of these incidents was the core meltdown of reactor 4 at Chernobyl, better known as the Chernobyl disaster. Introduction: Today I am going to tell you 3 things about Chernobyl.First, I am going to tell you what Chernobyl was.Second, I will tell you Why it happened and Finally, I will tell you what the effects were and why it’s relevant today.Body 1 â€Å"What was Chernobyl†? :April 26, 1986 in the early morning hours, an explosion rocked a thriving city near the heart of Ukraine.Within days 150 nearby towns had been evacuated.This explosion would become the beginning to the worst nuclear disaster in history.Chernobyl’s power reactors were graphic reactors, not commonly used anywhere outside of the Sovie t Union.In certain circumstances, the graphite reactors could speed up the nuclear reaction. This was a flawed Russian Design that ultimately led to the disaster.Chernobyl was classified as a category 7 nuclear event, the most severe classification according to the Nuclear Event Scale.Comparatively Three Mile Island was only classified as a category 5.Body 2 â€Å"Why did it happen? †:Next I am going to tell you why it happened.The disaster occurred due to an experiment which was being run by the reactor engineers.The purpose of the experiment was to determine whether electricity could be drawn from a turbine and redirected to the water pumps. High electrical demand during the day time meant they could not run the experiment until 11pm.The engineers grew impatient, reducing the rate of nuclear reaction too rapidly.Reducing the rate this quickly caused a rapid buildup of radiation poisons.To counteract this build up, the control rods were withdrawn. This meant they were no lon ger able to control the rate of reaction.These 2 critical errors (withdrawing the rods and slowing the reaction too rapidly) made the engineers incapable of increasing the power within the reactor. This was a safety precaution that the engineers overrode.Normally, in a situation where the reactor becomes unstable two fail safe measures were in place.   First, the power of the reactor could be increased to re-stabilize the nuclear reaction And Second, the engineers could wait 24 hours to allow the reaction chemicals to dissipateThe Engineers however, had already disabled the first failsafe be removing the control rods.The engineers also continued to turn off addition safety precautions including the emergency reactor cooling system. This system was designed to help stop the reaction if too much heat was generated.The emergency energy supply was also shut down, meaning there was no additional energy to run the plant.The experiment continued and the turbine generators were also shutdown.The electrical supply to the reactors water pumps was reduced as a result of the experiment, reducing the amount of cooling water passing through the reactor.Because of this, water within the reactor core began to boil.This was troublesome, since the cool water was used to reduce the heat of the reaction. As the rate of nuclear reaction continued to ac celerate, addition graphite tipped control rods were released by the engineers.Under normal circumstances, the control rods were designed to slow the rate of reaction.However, with the reaction already accelerating out of control, the insertion of the graphite rods further increased the reaction.After disabling or exhausting all potential failsafe methods, the engineers had run out of possibilities and had lost complete control of the nuclear reactor.Enough pressure had built up within the reactor to cause an explosion, leading to the collapse of reactor 4. Following the explosion, the engineers and reactor workers attempted to hide the incident from authorities.This meant that evacuation effort could not fully begin for 36 hours after the explosion.Because the incident was not immediately reported and the public was never made fully aware, farm produce, dairy and the air was contaminated with extremely high levels of radiation and extremely high levels of radiation and subsequently consumed by the residents in regions surrounding Chernobyl.Within hours of the explosion, residents of the nearby city of Prypiat began to fall ill.Body 3: How is it relevant to us? Finally, I’m going to tell you what the effects were and why Chernobyl is still relevant today.Hundreds of thousands of people were affected by the accident150 villages and towns were abandoned displacing thousands of people from their homes.As a result of the widespread release of radiation scientists estimate t hats 100,000 miles square miles surrounding Chernobyl had been significantly contaminated.Significant levels of radiation from Chernobyl were recorded at the Forsmark Nuclear power plant about 600 miles away from Chernobyl.Over 600,000 workers were involved in the cleanup of Chernobyl. Many of these workers received significant levels of radiation.The international atomic energy agency noted more than 1800 documented cases of thyroid cancer in children 14 and under immediately following the disaster, much higher than normal.Most of these were identified early and successfully treated.The disaster brought to light the severe effects of radiation poisoning on the body according to the international Nuclear safety group: â€Å"Krypton 85 affects the entire body and can increase the likelihood of developing cancer such as leukemia within two years of exposure. Cesium 137 can attack the entire body, centering on the liver, spleen and the muscles. Barium 140, gathers in the bones and can cause tumors as late as thirty years after exposure. Iodine 131 gathers in the thyroid. It can trigger cancer in the thyroid decades following exposure†.The event brought awareness to the dangers of radiation not only from nuclear reactors but also from everyday occurrences such as getting an X-Ray at the hospital.Conclusion:Nuclear reactors are used more today than ever. The nearest one is in Chicago, IL. The disaster of Chernobyl made people more aware of the dangers.More safety measures were put into place because of Chernobyl. These safety measures meant that containment and disaster relief was much faster and more effective during the 2010 Fukushima nuclear disaster in Japan. In conclusion I have told you what Chernobyl is, why it happened, what the effects and why it is still relevant to us today.ReferencesChernobyl | Nuclear Reaction | FRONTLINE | PBS. (n. d. ).

To sum up, Wahoo Bay Beach is an amazing place to visit mainly because of its view sight, nature sounds. Anybody who visits Wahoo Bay Beach would feel that he or she is in his or her own world.

Coping With Change Essay

P1- Discuss factors which affect the development of self-esteem M1- Compare two theories of self-esteem which contribute to our understanding of self-concept The NHS define self-esteem as being the opinion each individual has of themselves. NHS, (2015). It is the self-image and self –respect of an individual’s perception of themselves. Roshahl.c, (2008). This assignment is going to discuss the six factors that affect self-esteem. These factors are the growth promoting climate, the looking glass self, self-actualisation, ego identity, social identity and finally, the constructing of self-concept. Maslow stated that people are motivated to achieve certain needs. When one need is fulfilled a person seeks to fulfil the next one, and so on. Maslow, (1943). The self-actualisation theory was created by Maslow in 1943. This theory is based on the hierarchy of needs. This theory is an ongoing process. This theory is not something which is aimed for by a person, instead it’s something you do. In addition to this, the theory is not restricted to individuals; anyone is able to achieve this hierarchy of needs. The hierarchy is made up of levels these levels are; physiological needs, safety needs, love and belonging needs, esteem needs and finally, is all of the above are achieved, according to Maslow they are able to then reach self-actualisation. Maslowski.R.M, Morgan.L, (1973). The first stage of this theory is the biological and physiological needs, in order to achieve this a person must have the basic needs of living, they are; air, food, fluids, shelter, warmth, shelter, warmth and sleep. The safety needs of the hierarchy include protection from elements, security, order, law, stability and finally freedom fear. The love and belongingness stage of Maslow’s theory requires friendship, intimacy, affection and love from work colleagues, family, friends and romantic relationships. McGuire.K.J, (2012) pp281. The fourth stage of the hierarchy of needs is the esteem of needs, to achieve this stage an individual must experience achievement, prestige, self-concept, statues, dominance, mastery, self-concept and respect from others. The final stage is the self-actualisation. This stage involves realising personal potential, self-fulfilment, seeking person growth and  peak experiences. Maslow states that without achieving the first four stages, self-actualisation cannot be achieved. The second theory is Erickson’s Ego theory. This is another theory which is based on stages. Erickson’s theory focuses on the eight stages of life starting with infant and finishing with older age. The theory is a lifespan model of development taking in five stages up to the age of 18 years old and three further stages beyond the age of 18 and into adulthood. Each stage has a conflict, resolution and a cumilation in age these will all be presented in the table below. Age Conflict Resolution Cumiliation in age Infancy 0-1 years old Basic trust vs. mistrust Hope Appreciation of independence and relatedness Early childhood 1-3years old Autonomy vs. Shame Will Acceptance of cycle of life from integration to disintegration Play age 3-6 years old Initiative vs. Guilty Purposely Humour, empathy and resilience School age 6-12 years old Industry vs. Inferiority Competence Humiliation, acceptance of the course of one’s life and unfulfilled hopes Adolescences 12-19 years olds Identity vs. confusion Fidelity Sense of complexity of relationships, values of tenderness and loving freely Early Adult 20-25 years Intimacy vs. Love isolation Love Sense of complexity of life; merging of sensory logical and aesthetic perception Adulthood 26-64 years old Generative vs. Care stagnation Care Caritas, caring for others, empathy and concern Old age 65 years old -death Integrity vs. Despair Wisdom Existential identity, a sense of integrity strong enough to withstand physical disintegration The growth promoting climate theory suggests that a person requires a supportive environment that encourages an individual to grow positively. The theorist of this theory is Carl Rogers. The growth promoting climate theory is a person centred approach. The purpose of the person centred approach is to change, understand personality as well as human relationship. Jones.R.N, (2010) PP102. According to Carl Rogers, a positive involves diversity, empowerment which means to allow the individual to grow and achieve. Other factors which are required to create a positive environment is open communication, freedom and the capability to reach their full potential. However, without a positive environment, the growing promotion climate theory cannot be achieves. The looking glass self theory looks at how an individual views themselves. The theorist of this theory is Horton Cooley. The looking glass self is another theory that is separated into stages. This theory is made up of three stages. The first stage id that a person imagines how they are perceived and viewed by others. The second stage of the looking glass theory is when a person imagines how they are judged by others and this is based and concluded by the first stage of the theory which is how a person imagines they are perceived by another individual. The final stage of  this theory is the experiencing of a type of feeling or reaction to the staged in one and two. Gbadebo.S.A, (2011), pp124. For example a person may believe that they are perceived as being polite and friendly to another individual. This would be the first stage of the theory (imaging how they are perceived by others). This would therefore lead to the individual imagining they are judged in a positive light and a well-mannered individual. This would be the second stage of the theory (the way in which a person imagines they are judged by others). The way in which an individual acts towards them would determine the opinion they have of them. Gba debo.S.A, (2011), pp124. If a person who is isolated in a situation is judged to be a polite friendly individual they are more likely to make friends as they may give off a friendly vibe encouraging people to want to engage with them however if they were perceived as being rude and arrogant, other may not want to associate or include the individual in their conversation and may even think the individual is purposely isolating themselves from the situation. The Social identity theory was created by Henri Tajfel in 1979. He proposed that groups which people belonged to were an important source of pride and self-esteem. These groups may be a person’s social class family or a person’s choice of football team. Groups give individuals a sense of identity and sense of belonging to the social world. Burke.P.j, (2009). This theory focuses on how we perceive and make sense of each other. This helps with the construction of society and culture. This theory suggests that people are interested in the information of others such as their beliefs, intentions and affiliations. Tajfel. H, (2010). This enables a person to interpret and understand the words and actions of another person as well as their decision makings. This also allows a predication of a person’s future. The final factor that affects a person’s self-esteem is the constructing of self-theory. A sense of self or personhood, of what kind of person one is. Identities always involve both sameness and difference, (2000) Penguin Dictionary. ‘Identity is about belonging, about what you have in common with some people and what differentiates you from others. At its most basic it gives you a sense of personal location, the stable core to individuality. But it is also about your social relationships, your complex involvement with o thers’ (1996). This theory consists of three main arguments they are; We are born with our  identities; identities and culturally and historically dependent, identities are fluid and fragmented and are a result of conscious and unconscious thought and emotion (affective attachment to particular identities). This theory consists of sources of identity, they are gender, age, sexuality, ethnicity, social class, consumption, employment, roles and responsibility, family networks, friendships, use of technology, politics, leisure activities and finally the body. All of the discussed theories are all contributing factors to the development of person’s self-esteem. All of which explain have a different understanding. Some were evidently based on the needs of an individual in order to live such as Maslow’s hierarchy of needs, others focused on the different stages of life a person experiences such as Erickson’s eight stages of life. M1- The aim of this next task is to compare two theo ries of self-esteem which contribute to our understanding of self-concept. The two theories this assignment is going to focus on are Erickson’s eight stages of life theory and Maslow’s hierarchy of needs. The first similarity of these two theories is that they are both broken down into stages however Maslow’s hierarchy of needs is split into five stages Maslow. A.H, (2013) whereas, Erickson’s life stages are split into six. The different number of stages is on difference between the two theories. A further difference between the two theories is that Erickson’s stages are based on the stages of life every individual experiences. Therefore the theory can be easily generalised to all individuals during a specific age group. In addition to this, Erickson’s ego theory is structured in a timeline of stages. However, the stages of Maslow’s hierarchy of needs are the requirements needed in life such as warmth, shelter, love and family. Rakowski.N, (2011). Therefore Erickson’s theory focuses on experience whereas Maslow’s theory focuses on the needs of an individual and the goals of achievement of an individual. An additional difference between Maslow’s and Erickson’s theory is that Maslow states that without successfully achieving one stage a person cannot proceed to achieve the next stage preventing a person for achieving actualisation. Erickson’s eight stages of life are experienced by all individuals throughout their life span and therefore all stages are experienced and unresolved stages can be resolved in later stages in life. Tiffany.L, (2014). Erickson’s ego theory focuses on psychosocial stages whereas Maslows hierarchy theory focused on the needs  of an individual. The year the two theories were developed is another comparison, Erickson’s Ego theory was developed in 1950 whereas Maslow’s hierarchy theory was developed in 1943. Erickson’s Ego theory has an overall finishing point which is when an individual achieves self-actualisations whereas Maslow’s hierarchy of needs is a continuous cycle which continues until a person reach death. Tiffany.L, (2014). A final comparison of the two theories is that Erickson’s Ego theory was influenced by a theory which already existed; this was Freud’s theory regarding the structure and topography of personality. Maslow’s hierarchy theory on the other handed was an extended version of his own work rather than the work of others. Chapman, (2001). Both the theories of Abraham Maslow and Eric Erickson support the use of human response assessment in the experimental and behavioural perspectives. Mcleod.S. Erickson’s eight stages of life also identifies task which must be achieved at each stage and similarly to Maslow’s hierarchy of needs, if these tasks are not achieved, a person cannot proceed successfully achieve the next tas k.

Different Styles in Movies Essay Example | Topics and Well Written Essays - 1250 words

Different Styles in Movies - Essay Example The essay "Different Styles in Movies" investigates such movie styles as Soviet Montage, Surrealism, German Expressionism and Impressionism. Equally important is the use of dream sequence to penetrate in to the layers of mind – conscious and subconscious. This style the focuses on the characters’ state of mind, impression of feelings and emotions rather than on the plot or drama of the story. Cinematography and editing are used to illustrate the state of mind, and dream sequences are used to reflect on the conscience. The wide use of impressionist methods is so palpable in Francis Ford Coppola’s film, that brought the internalized life of a detached expert ‘bugger’ Hary Caul on the scene. He would pass for a modern recluse, donned with headphones, holding an extended shot gun microphone. He probes into the private life of Ann and Mark. The film revealed contradictions in the inner and outer life of the protagonist through the subtle emotions on his f ace, physical movements, and also in his dialogue which intermittently gets spiced with silence. The camera opens with a bird’s-eye-view on the busy lunch time at Union Square in downtown San Francisco, with frames having visual details of pedestrians, workers on lunch break, and Christmas shoppers. There emerges the cadence of street musician’s concert which gets mingled with the gruff and hoarse noise produced by certain mechanical devices in the street. The inner conflicts of the character are illustrated through the varying degrees of music and cacophony.

Sedimentary Rocks Essay Example | Topics and Well Written Essays - 1250 words

Sedimentary Rocks - Essay Example The key characteristic feature of sedimentary rocks is that they are layered. Although there cover of the earth’s crust is extensive (about 75 per cent), sedimentary rocks only constitute about five per cent of the total volume of the crust. The earth’s crust mainly consists of the igneous and metamorphic rocks. Sedimentary rocks are vital sources of the natural resources such as coal and drinking water (Stille and Fichter, 2008). Formation of Sedimentary Rocks Sedimentary rocks are usually formed in areas where there is water or water had existed in one particular time. The dead materials of animals, plants, and pieces of rocks or minerals are then transported to these areas (water bodies) by wind, water, ice, or gravity where they are often dropped off and sink to the bottom. At the bottom of the water bodies, they little by little begin to form layers which build on top of one another. This puts pressure on the lower layers thus the weight of all of the layers pushes down the lower layers until they harden into rock.   This process does not occur in few years but takes millions of years to happen.   During this process, the water body dries up and the sedimentary layer that used to be under water becomes a surface layer (Boggs, 1995). Categories of Sedimentary Rocks According to Stille and Fichter (2008), sedimentary rocks are categorized into three main groups based on sediment type. The three categories include: Clastic Sedimentary Rock: they are formed from mechanical weathering debris. Examples include sandstone, conglomerate and breccias. Organic Sedimentary Rocks: they are formed from accumulation of dead plant and animal materials. Examples include coal and some limestones. Chemical Sedimentary Rocks: they are formed by precipitation of dissolved materials from solutions. Examples include some limestones and rock salt. Distinguishing Characteristics between the Three Categories of Sedimentary Rocks Clastic Sedimentary Rocks These are the most common type of sedimentary rocks and are comprised of granular materials which occur in sediments. Clastic rocks largely consist of surface minerals such as clay, feldspar and quartz which are formed as a result of physical breakdown of rocks and alteration of rocks chemically. Clastic sedimentary rocks are classified according to the size of the particle which is dominant in the rock. For example, Breccia is composed of large angular fragment, sandstone is composed of sand size weathering debris and conglomerate is made up of large rounded particles. Clastic sedimentary rocks have clastic texture; they are made up of clasts (Stille and Fichter, 2008). Organic Sedimentary Rocks Organic sedimentary rocks are composed of organic matter: animal and plant fragments. This type of rock is usually formed in two ways. One type (which includes limestone and chest) forms in the sea due accumulation of dead plankton shells whereas as the other one (coal) is formed due accumulation of dead plant on the earth surface (Boggs, 1995). Chemical Sedimentary Rocks Chemical sedimentary rocks are formed by inorganic precipitation of supersaturated mineral constituents. They form within the depositional basin from components of chemicals dissolved in water. Unlike clastic sedimentary rocks, the direct origin of chemicals is not east to esteblish. The chemicals could originate from magma or from an
