...Bringing up the government and politics can always exemplify hatred and love. In an always changing society these two topics are a constant battle deciding if your pro government’s choice or hate it with all your guts with their decision. In order to have a peaceful and civilized society we must come to some mid point to accept and argue respectfully with there being no violence to stir up. Maintaining order, public goods, and equality all share one aspect and that is they all affect us everyday of our lives. Maintaining order and equality correlate with the peace and violence that occurs everyday in our society. Whether that be violent protest about equality or maintaining order from people doing whatever they want. The government should play a role in our lives because it ensures equal opportunity, regulations, and peace in our society. Equal opportunity exemplifies a conflicting problem for hundreds of years. As far back when there was slaves in the south and to this day equal opportunity has brought violent protest and many lives to be cut short. This...

...Board of Education was a major turning point in the history of the United States. This major case was actually several cases that were decided by the Supreme Court as one. These cases were argued by the NAACP and their expert team of lawyers led by Thurgood Marshall and his team the Legal Defense and Educational Fund. All the cases were filed by African American parents on behalf of their children. The parents of these children wished it to be brought before the courts that “separate but equal” was not fair. In the South though, Plessy v. Ferguson, “separate but equal” and Jim Crow laws reigned, they had a tough battle ahead.Leading up to Brown v. Board of EducationThe Jim Crow Laws were enacted in mostly the Southern and some of the border states of the United States and enforced between 1876 and 1965, slightly less than a hundred years (wikipedia). These laws mandated "separate but equal" status for black Americans. “In reality, this led to treatment and accommodations that were almost always inferior to those provided to white Americans. The most important laws required that public schools, public places and public transportation, like trains and buses, have separate facilities for whites and blacks” (wikipedia). In the Progressive Era the restrictions were formalized, and segregation was extended to the federal government by President Woodrow Wilson in 1913 (wikipedia).To discuss the Supreme Court case of Brown v. Board of Education, a brief history of the major case that had...

...hroughout history equal rights has always been a major issue in the United States, and around the world. People have fought and even died to protect their rights and the rights of others in this country. Most people assume that colored citizens are the only ones that are affected by the lack of equal rights, but thats not true. Women have been discriminated against since the beginning time, but in present day that is greatly diminishing. Today women and men do have equal rights by law, and that only holds aloft in the court houses. On the streets women have to deal with a different story every day of their lives. No matter where a woman goes she feels like she is inferior to most men. Men have always been the manipulate sex, that is a proven fact, but women should not have to feel that way...

...civil rights are something that everyone is granted. However, history has shown that this has not always been the case. In the United States, civil rights are supposed to be for all people. Throughout history, there have been many disagreements in the Civil Rights Movement. One group who shared a negative opinion about the advancement of black people is the Ku Klux Klan. The Ku Klux Klan opposed equal rights between whites and blacks and used violence to show their opinion. The Ku Klux Klan also known as the KKK or the Klan, had a large, negative impact on the long struggle for civil rights. The KKK impacted the Civil Rights Movement by killing or lynching both black and white people who fought for equal rights. For...

...Geometry Geometry is all about shapes and their properties. If you like playing with objects, or like drawing, then geometry is for you! Geometry can be divided into: Plane Geometry is about flat shapes like lines, circles and triangles ... shapes that can be drawn on a piece of paper Solid Geometry is about three dimensional objects like cubes, prisms and pyramids. Plane Geometry Plane geometry is all about shapes like lines, circles and triangles ... shapes that can be drawn on a flat surface called a Plane (it is like on an endless piece of paper). Plane A plane is a flat surface with no thickness. Our world has three dimensions, but there are only two dimensions on a plane. Examples: • • length and height, or x and y And it goes on forever. Examples It is actually hard to give a real example! When we draw something on a flat piece of paper we are drawing on a plane ... ... except that the paper itself is not a plane, because it has thickness! And it should extend forever, too. So the very top of a perfect piece of paper that goes on forever is the right idea! Also, the top of a table, the floor and a whiteboard are all like a plane. Imagine Imagine you lived in a two-dimensional world. You could travel around, visit friends, but nothing in your world would have height. You could measure distances and angles. You could travel fast or slow. You could go forward, backwards or sideways. You could move in straight lines, circles, or anything so long...

...Women throughout history have always had to struggle in being treated equal. Women have always had to fight for their rights. They have been discriminated, denied the right to vote, earn lower wages, and have had to struggle a lot more than men. A lot of this comes from how males are seen as macho and can do more than women. These challenges for women in the US are also role that I have seen in my Hispanic culture. The primary role of man under the Hispanic culture is emphasized as “machismo” which means that a man is the great provider of the family. Men should work and strive hard to protect their families and provide them with all their needs. Men in Hispanic culture are noted to be fearless and strong. On the other hand, the roles of women is referred to as “Marianismo”. Their primary role is to be loving and caring mothers. I feel that those views are like the US. That is why I chose senate bill 60 for our project to take to the capital. Senate bill 60 was...

...should be treated equal to men. I am also going to get you a reason why some would think that women aren’t equals to men. While there are some things men to better because they are naturally stronger than women, I do think that women and men are equal because women are just as strong as men mentally and spiritually and that is very important. Women have proven over the years that as long as they put there mind to doing anything it can accomplish, just like a man, in the world today women are doing everything that men are doing and some are even doing it better than men. First, I think that women and men are equal because women are just as strong as men mentally and spiritually so why shouldn't they we are consider equals. In terms of equality, I do see that women are more evolved mentally, spiritually and emotionally. That's why women seem to have a heighten sense of a taste, smell, sound and even sight. However, the problem is that society doesn't promote these things society promotes male qualities and for that reason along women aren’t treated fairly. Additionally, Women have proven over the years that as long as they put their mind to it they can accomplish everything a man can. If we go back in time we will see that women are astronauts, doctors, lawyers, and construction workers as well, which were all male dominated jobs before. After doing some research I found that a lot of information and a lot of people (men) don’t agree that women are just as equal to them. However...

...Stereotyping Cassandra Britt PHI 103 Informal Logic Professor Anna Morrison January 14, 2013 Stereotyping When I started looking and thinking about stereotypes the first one that comes to mind is single mom. When you think of single mothers, people always feel that the person is on welfare and not able to take care of her children or herself. That is really a misconception. Sometimes the mother may have chosen to have a child and raise it by herself. The spouse could have passed away and the mother chooses to not remarry. There is numerous reason why a woman chooses to be a single parent. I myself encounter this when I had my first child growing up in the church and with my own family and friends. I wasn’t allowed to sing in the choir, people constantly talked about you behind your back. I felt that it was all because my parents had divorced, but both of them were still active in our lives. “There’s no question that single-mother families struggle in ways that two-parent families don't. Unmarried women juggling jobs and children are apt to have less money, less time and fewer emotional resources to devote to their kids” (Banks, 2012). The big picture is that there are single mothers that are not on welfare and have a wonderful support system. “The label "single mother" doesn't recognize that. Its fallout swirls around all of us raising children without fathers, like the dust cloud that followed Pig Pen around in those old "Peanuts" comics” (Banks, 2012). The...

...that they both know as well as understand what personal responsibility is, but sometimes that's not always the case. To understand one's own personal responsibility you must always own up to your own actions. Therefore, you must take charge of your actions by practicing discipline and using time management skills. Thus, for every action there is an equal and opposite reaction. Personal Responsibility to me means to, acknowledge responsibility for my choices and being accountable for my own actions. Is important to acknowledge personal responsibility and to never point the blame to someone else in order to be successful. There those who you may either work with or just may be around that think doing whats right is a bad idea or say "it's your funeral", but by taking responsibility for what happened and by knowing that you are at fault for it is always the best way to go. Thus, always tell yourself that by doing the right thing is being personal responsible. Every action creates an equal and opposite reaction, which means that whatever actions you take in life will affect your college success. A perfect ex. would be procrastination, if you take too long on an assignment or forget to do the assignment then it will come back on you when the day comes to turn it in. Therefore, never put off til tomorrow what can be done today. Not one person in the entire universe will always have the same view's on personal responsibility as another person. One person's view on personal responsibility...

...“At the Twilight's last gleaming…For the land of the free,” these are lyrics, written by Francis Scott Key when he was overcome by the feeling of freedom. Though in society now, that is just the opposite. Harrison Bergeron by Kurt Vonnegut Jr. show exactly that, with putting handicaps on everyone to try to make everyone equal. Harrison Bergeron, and fourteen year old, breaks out of jail to show everyone who he really is on live television. A possible theme for Harrison Bergeron is, everyone is beautiful in their own ways, and should be allowed to express them, however, another possible theme may be, life is not fair, deal with it. Harrison Bergeron’s society is broken. The government makes everyone think and act as though everyone is equal....

...should assume equal responsibility in raising a child As you grow up, you are taught many life lessons from your experienced parents. Your parents' duty is to nurture you, so that you can grow up to become a person who is strong and able to support oneself. Parents must realize that when it comes to raising a child, they both must put in an equal amount of effort so that the child learns new things, prevents family breakdowns and prevents the child from straying off the 'right' path. You learn to cook when you're helping mum bake cookies in the kitchen, you learn to fish when you're out with dad camping, but if only mum teaches you how to cook and dad is 'too busy' to take you out to go fishing, then you've lost a new experience you could've discovered. There are so many different things your parents can teach you. But if only one parent puts in that effort and the other doesn't, then your knowledge and mind will not be able to become more open and aware of all the wonderful possibilities out there. Therefore, both parents should assume equal responsibility when raising a child.Your dad always comes late from work and never has any time for you and your mum is always around you, looking after you, caring for you. When your mum has finally 'had enough', what will happen then? Your dad's too busy, your mum is too stressed, how are you to go about your daily life once the fights between mum and dad become too much? Unfortunately due to parents not putting in an equal commitment...
