The Effects of Aging - 2133 Words

Everyone, at some point or another, loses keys, misplaces a wallet, or forgets a name. It is a normal experience, but people who are middle-aged or older may be frightened about the onset of Alzheimers disease or another type of dementia. The American Psychological Association offers the assurance that Alzheimers is not a normal part of aging, occurring in fewer than one in five people over the age of sixty-five and less than half of those over eighty-five (Memory and aging, 2009). The research of Reese and Cherry (2006) supports the assertion that, for most people in middle age, forgetting is not serious. Nevertheless, changes take place in the brain as one ages with respect to learning and memory. The purpose of this paper is to explore some of the normal changes people can expect in mid- to late-life as well as some of the problems one can experience outside the normal effects of aging. The human brain reaches its maximum size during ones early twenties, then very slowly starts to decline in volume (Memory and aging, 2009). Over time, ones heart muscle becomes less efficient and has to work harder to pump the same amount of blood through the body (Mayo Clinic Health Information, 2011). It means the brain gets less blood and less oxygen, resulting in a decline in the number of neurons. The brain decreases in volume and, between the ages of twenty and ninety, loses five to ten percent of its weight.

Discipline and Punishment Free Essays

The words discipline and punishment can often be used to mean the same thing. But they are very different from each other. To me discipline is a means of helping a child to learn how to act when they are in public as well as when the parent is not around; for example whether it be at school, their grandparents house, or when being babysat a child should always act as if their parents are there which means; being respectful, listening as well as doing what you are told. We will write a custom essay sample on Discipline and Punishment or any similar topic only for you Order Now I feel like discipline should never stray away from the fact the you are trying to focus on the positive aspects and self esteem of the developing child. The reason for discipline is to help a child learn how to control their behavior as well as their emotions and the child should be reassured with firm reminders. Punishment is also another form discipline. There are several methods to physical punishment which would including spanking, push-ups, squatting against a wall, or even hitting. There are psychological punishments such as taking away privileges, extra chores, writing sentences, or sending a child to their room. The reason for punishments is to discourage unacceptable behavior. To most people discipline and punishment can be viewed as the same, but there are certain methods to discipline and punishment that are different. Punishment and discipline methods both have some similarities that attempt to correct the negative behavior at hand. Punishment removes the accountability for the misbehavior from the child. Punishment is not really teaching a child what they did is wrong and what to right the next time. Punishment is ultimately telling the child if they do something wrong then they will be punished whether it be push ups, extra chores, or TV. taken away. Children need to learn that they need to take accountability for their own actions to be able to exercise self-control so that they can be successful as well respected adults. The objective of punishment is to stop a child from misbehaving. However, punishment usually only stops the behavior for that short period of time the punishment is given. Punishment does not necessarily not teach a child how to not do the same behavior again in the future. Severe punishments can cause physical and emotional damage that could last throughout a child’s life. Harsh punishments can also lead to abuse which could follow on to their children as well. Another difference between discipline and punishment is that punishment only works in the present. If a child is punished by being spanked or screamed at, they will learn not to misbehave when someone can see what they are doing but, they are not learning how to not misbehave in the future. Discipline is designed to teach a child how to exercise self-control and how to not repeat the misbehavior in the future. For example if the child is with a group of friends who decided to do drugs, that child has been taught through the discipline and guidance of their parents that drugs are bad. So as a result the child has enough self-control and discipline to know not to follow in their friends footsteps. Discipline and punishment are different in that discipline is an on going learning process that allows parents to teach their child self-control, respect, and the importance of acceptable behavior and non-acceptable behavior. In life a child is going to become an adult and be faced with obstacles and barriers; that will test their morals and values that their parents instilled in them. Parents have a responsibility to communicate their expectations to their child in a manner that the child will understand. Which also means knowing what is acceptable behavior and what is not acceptable behavior. There are many types of discipline, and punishment is one of them. Punishment can work in the moment, but as a parent it is their job to commit to a discipline process that is ongoing throughout their child’s development to truly change the behaviors in a child Discipline and Punishment How to cite Discipline and Punishment, Papers

Compares 19th Cent. British 1920s German art schools. Looks at the origins, critiques of society modernization, leadership, love of beauty utility. The Arts and Crafts Movement, that began in nineteenth-century Britain, and the Bauhaus movement, that started in Germany in the 1920s, had many goals in common. Both movements were interested in uniting all the arts and crafts and giving them equal dignity. Both movements were also deeply concerned with the role of the artist as worker and with the nature of work in general. Most importantly, both movements believed in beautiful design and well-made work as an enhancement of life. The importance of industrialized production and its aesthetic effects was a central question for both movements, but this was also the main point on which they disagreed. Both movements held that the industrialized production of goods had transformed the world. But, while the original Arts and Crafts movement largely rejected the machine age and all its productions, the Bauhaus.

The Gold Fish And The Fisherman Essays - Go, Ko Fight, Fishing

The Gold Fish And The Fisherman Once upon a time there was an old man named `Ko'. Ko was a fifty-year old fisherman. He liked children very much but unfortunately he and his wife Jean did not have any of their own. Sometimes he felt quite lonely at home. Ko and Jean lived close to the harbour. One thing that Ko did not like about Jean was her temper. Very often she yelled at him for no reason at all. One morning while Ko was still sleeping Jean yelled at him, "Wake up! Its very late now. You should go fishing. Every day you go fishing and do not become bored. Why don't you build a house in the middle of the ocean?" said Jean said with much criticism. Ko did not reply. "Hey! do you hear me?" asked Jean. "Yes dear," Ko replied. "Then why didn't you answer me? Some day you're going to drive me crazy", said Jean. "I was waiting for you to finish talking. Don't be so angry. I'm leaving right now", said Ko. Ko quickly got dressed and left for the harbour. On his way to the harbour he met his good friend `Sun'. As they were walking down the trail to their fishing boats they started a conversation. "Hey, today's weather is very good eh? I bet there will be a lot of fish," said Sun. "It's hard to say nowadays. During this season we can't tell if there will be any fish," replied Ko. "Yes, I agree. During the last few days it appeared as though the fish were all hiding. You're lucky that you only have a wife to feed while I have a whole family to take care of. Sometimes my whole family had to starve if there was no fish.", said Sun. "Don't say that. To me I think we're all the same. As a matter of fact I think you are more fortunate than I.", said Ko. "Why? " asked Sun. "At least you have grand children and family members. In fact you don't even have to go fishing anymore," said Ko. "No way! Fishing is my hobby. I've been fishing for many years. If I stop fishing suddenly I just don't feel comfortable," said Sun. "Isn't that the truth? Just look at the ocean. It's beautiful isn't it?" said Ko. "It sure is" answered Sun. Ko and Sun had arrived at their boat. They wish each other good luck. Then they got on to there boats. The day passed very quickly and soon it was sunset. Ko lifted his last net to see if he had caught anymore fish. When he pulled up the net he noticed he had caught a Gold Fish. "This is strange! I didn't know that there were Gold Fish in the ocean.

Polymer Definition and Examples

Polymer Definition and Examples A polymer is a large molecule made up of chains or rings of linked repeating subunits, which are called monomers. Polymers usually have high melting and boiling points. Because the molecules consist of many monomers, polymers tend to have high molecular masses. The word polymer comes from the Greek prefix poly-, which means many, and the suffix -mer, which means parts. The word was coined by Swedish chemist Jons Jacob Berzelius (1779–1848) in 1833, although with a slightly different meaning from the modern definition. The modern understanding of polymers as macromolecules was proposed by German organic chemist Hermann Staudinger (1881–1965) in 1920. Examples of Polymers Polymers may be divided into two categories. Natural polymers (also called biopolymers) include silk, rubber, cellulose, wool, amber, keratin, collagen, starch, DNA, and shellac. Biopolymers serve key functions in organisms, acting as structural proteins, functional proteins, nucleic acids, structural polysaccharides, and energy storage molecules. Synthetic polymers are prepared by a chemical reaction, often in a lab. Examples of synthetic polymers include PVC (polyvinyl chloride), polystyrene, synthetic rubber, silicone, polyethylene, neoprene, and nylon. Synthetic polymers are used to make plastics, adhesives, paints, mechanical parts, and many common objects. Synthetic polymers may be grouped into two categories. Thermoset plastics are made from a liquid or soft solid substance that can be irreversibly changed into an insoluble polymer by curing using heat or radiation. Thermoset plastics tend to be rigid and have high molecular weights. The plastic stays out of shape when deformed and typically decompose before they melt. Examples of thermoset plastics include epoxy, polyester, acrylic resins, polyurethanes, and vinyl esters. Bakelite, Kevlar, and vulcanized rubber are also thermoset plastics. Thermoplastic polymers or thermosoftening plastics are the other type of synthetic polymers. While thermoset plastics are rigid, thermoplastic polymers are solid when cool, but are pliable and can be molded above a certain temperature. While thermoset plastics form irreversible chemical bonds when cured, the bonding in thermoplastics weakens with temperature. Unlike thermosets, which decompose rather than melt, thermoplastics melt into a liquid upon heating. Examples of thermoplastics include acrylic, nylon, Teflon, polypropylene, polycarbonate, ABS, and polyethylene. Brief History of Polymer Development Natural polymers have been used since ancient times, but mankinds ability to intentionally synthesize polymers is a fairly recent development. The first man-made plastic was nitrocellulose. The process to make it was devised in 1862 by British chemist Alexander Parkes (1812–1890). He treated the natural polymer cellulose with nitric acid and a solvent. When nitrocellulose was treated with camphor, it produced celluloid, a polymer widely used in the film industry and as a moldable replacement for ivory. When nitrocellulose was dissolved in ether and alcohol, it became collodion. This polymer was used as a surgical dressing, starting with the U.S. Civil War and afterward. The vulcanization of rubber was another big achievement in polymer chemistry. GErman chemist Friedrich Ludersdorf (1801–1886) and American inventor Nathaniel Hayward (1808–1865) independently found adding sulfur to natural rubber helped keep it from becoming sticky. The process of vulcanizing rubber by adding sulfur and applying heat was described by British engineer Thomas Hancock (1786–1865) in 1843 (UK patent) and American chemist Charles Goodyear (1800–1860) in 1844 (US patent). While scientists and engineers could make polymers, it wasnt until 1922 that an explanation was proposed for how they formed. Hermann Staudinger suggested covalent bonds held together long chains of atoms. In addition to explaining how polymers work, Staudinger also proposed the name macromolecules to describe polymers.

Primate Observations Research Paper Example | Topics and Well Written Essays - 1250 words

Primate Observations - Research Paper Example Different species of the order primates responded differently to their respective subsequent environments thereby resulting in unique adaptive features thereby becoming completely different animals. Humans are the most civilized of the primates and possess distinct features from the rest of the non-human primates such as monkeys, chimpanzees, and apes among others. However, some of the non-human primates possess characteristics similar to those of humans thereby corroborating the common ancestry theory and the theory of evolution all of which seek to explain the origin of the different animals (Waal and Frans 55). Apes are arguably the largest arboreal animals implying that they are the largest mammals living in trees. The primates are of the biological family known as Hominoidea of the family Homo thereby making them very closely related to humans. They therefore have numerous personality traits similar to those exhibited by humans. The primates are herbivores and natives of Africa and East Asia owing to the existence of large tropical services that provided adequate habitation. Currently, they live in different parts of the world owing to animal transportation by humans and their own migrations as conflict between them and humans heighten. However, some of the apes can eat other animals a feature that quantifies the primates as being both carnivores and herbivores. Monkeys on the other hand are a category of primates of the family cacopithecidae. Just as any other primate, they are natives of Africa and parts of East Asia and are of numerous species. The deferment species possess different features with a majority of the species being arboreal while others leave on the ground. Monkeys have tails that they use frequently in their daily survival activities. They are smaller than any other primate is and live in groups consisting of both males and females. Apes and monkeys as observed during the tour of the zoo exhibit a number of traits similar to those of huma ns while others are strange and therefore set them apart from the rest of human primates. Their different characteristics are results of their different habitats occurrences that validate the evolution theory and its elated adaptations. Apes and monkeys live in groups, they are social animals a feature that distinct the primates from the rest of other mammals. The animals are social and therefore live in societies consisting of males, females, and children. In their societies, the adults protect the young ones and provide them with food. This is typical of humans who are also very social and coexist peacefully with one another despite the constant competition for food among other resources. Additionally, humans show affection and protection to their children. The monkeys and apes showed great protection to their babies often carrying them below their bellies. In case they released their babies, the mothers ensured that the company was safe and only among other monkeys or apes. This way, the other apes teased the baby and played with it before sharing their meals with it. Additionally, the apes and the monkey showed affection to the old amongst them. While they fought for the food thrown at them, they never scrambled for those that fell close to the old. This is synonymous to human who are the most civilized primates and show great affection to both their old and the young. The theory of evolution and the evolution of humans assert that before inventing the upright position, humans just like the rest of the non-human primates carried their babies on their underbellies (Kinzey 34). This position proved convenient for walking on the four feet and for handling both food and tools. The primates at the zoo corroborated this claim. With their babies in
