Emotional Disorder Behavior Essay -- essays research papers

Parents today face the dilemma of having a child with emotional or behavioral disorder. For small children, to have it is one thing, but to detect it is another. Since they are still growing up and going through stages such as the â€Å"terrible two’s† and adolescence, you’d think that some of their behavior is normal and it’s all a part of child development. It all depends on how one may look at it. If a small child were to have a severe tantrum and rip their toys apart, one parent may see it as a serious behavioral problem, while another may look at it as their child showing independence or leadership skills. Before seeking mental health assessment, parents must first look at the whole picture. Is the child having social issues at school? Are there any family problems such as divorce or death occurring? Alternatively, may be a specific condition the child has may be affecting their behavior? Whatever the situation may be, parents should first try and un derstand and be aware of the problem that is going on.   Ã‚  Ã‚  Ã‚  Ã‚  All toddlers, behaviors range differently and may be considered normal for their age. Yet, if there is a delay in language development, in which an infant who is unresponsive to his her environment (doesn’t show emotion such as pleasure or fear that is developmentally appropriate, doesn’t look at or reach for objects within reach or respond to environmental changes such as sound or light), who is over-responsive (easily startled, cries), or who s...

Vitamin C in Different Fruit Juice

Activity 1. 21- Is high Vitamin C all it claims to be? Purpose: * To investigate the vitamin C content of fruit juice * To investigate which type of fruit juice provides the most vitamin C The quantity of vitamin C in food and drink can be determined using a simple colour test. Vitamin C decolourises the blue dye DCPIP (dichlorophenolindolphenol). Vitamin C is an antioxidant and reduces the DCPIP. DCPIP changes from blue to colourless (or slightly pink) as it becomes reduced. We will be testing a range of different fruit juices to see which contains the highest concentration of vitamin C Hypothesis: I predict that the orange might be the juice that provides the most vitamin C; this is because it is widely promoted as a ‘high vitamin C juice’. * Grapefruit juice might contain the second highest amount of vitamin C; also because of it promotion in the media. Vitamin C is a water-soluble compound that is essential for life. It is involved in many processes in the human body , including: the production of collagen in the connective tissue; the synthesis of dopamine, noradrenaline and adrenaline in the nervous system; and the synthesis of carnitine, which is important in the transfer of energy to the cell mitochondria.A deficiency in vitamin C causes scurvy, a disease that affected sailors in the 16th – 18thCenturies. It was discovered that fresh fruit, e. g. limes and oranges, or sauerkraut (preserved cabbage) provided the sailors with protection from scurvy. Safety: * Running should be avoided in the laboratory to prevent accidents especially when handling liquids * Goggles should be warn at all times when carrying out the experiment * Care should be taken when handling glass wear * The supervisor should be informed about any spillages of liquid that may be hazardous to others in the laboratory. Controlled variables: Temperature; If a juice is higher in temperature than the other, it will cause the reaction to speed up which would make the exper iment unfair. * Concentration of DCPIP; different concentrations would not benefit the experiment as we are only changing the type of juice. * Shake each flask using the same movements; more vigorous movements may add oxygen which would affect the DCPIP and turn it slightly blue again. * Same end point colour (colourless); attention and concentration should be given to see through until the very last drop so the volume is not increased. Independent variable: * Fruit juice Dependant Variable: Volume of juice required to decolourise the DCPIP. The experiment procedure: Equipment: * 1% DCPIP solution * Vitamin C solution * Range of fruit juices * Conical flasks * Beakers * Pipette accurate to 1cm3 to measure volumes accurately * Burette to measure volumes accurately * Safety goggles Method: 1. Pipette 1cm3 into a beaker 2. Fill the burette with the vitamin C solution 3. Add the vitamin solution in droplets 4. As soon as the DCPIP goes colourless, stop the burette and record the volume of vitamin C solution that was used. 5. Repeat this procedure with other juices 6. Repeat the experiment at least 2 times . Calculate the mean result for each juice Table of results: | Vitamin C| Orange| Grapefruit| Lemon| Blueberry| Pineapple| | 1| 2. 5| 3| -| 2| 13| | 0. 4| 2. 4| 1. 95| 1. 1| 3| 12. 75| | 0. 35| 0. 4| 1. 15| -| 0. 8| 8. 2| | 0. 1| 2. 1| 4. 7| 1. 7| 1. 5| 8. 2| | 0. 1| 1. 96| 4. 6| 2. 3| 1. 8| -| AVERAGE| 0. 39| 1. 96| 3. 08| 1. 9| 1. 8| 10. 5| Here the least volume of juice needed to decolourise DCPIP was the blueberry juice, followed by lemon then orange juice. From the experiment, blueberry juice provided the most vitamin C because less of it was needed in order to turn DCPIP colourless.The pineapple juice was the juice that let out the highest volume from the burette in order to decolourise DCPIP; this is because it was the juice that provided the least amount of vitamin C. All of the juices had vitamin C in them as the highest volume was only 10. 5cm3. The res ults obtained from the experiment showed no relation to my hypothetical prediction. It may have been because of the experimental errors that had been overlooked whilst carrying out the experiment. The results from the experiment did not agree with the widely publicised fact that orange juice provides the most vitamin C.A number of errors could have been made: the temperature may not have been the equivalent for all juices( the last juice to be measured may have been at a higher temperature than the rest causing the reaction with the DCPIP to hasten), the amount of shaking may of effected the results as too much shaking could have added oxygen which would have restored the DCPIP to blue, the end point may have been difficult to judge because of it close proximity, some juice may have been lost whilst it was being transferred from the beaker , there might have been an error in how accurate the juices were measured or recorded.In the future more attention could be given and the experim ent could be done more slowly; time may have been an issue when carrying out the experiment. The results obtained were pulled together from different groups in the class who may have all treated their readings and measurements differently, therefore it would be much reliable if I repeated the experiment and obtained at least three readings for each juice on my own. Moreover, the juices bought could all be from the same brand, this is because some manufacturers put more sweeteners or fresh juice than others.

Communication Theories Matrix Essay

Instructions: Complete the following matrix by filling in the box for each of the five communication theories with the following four items: the theory definition, the main principles of the theory, a real-world theory example, and an application of each theory to virtual communication. Theory definition Main principles of the theory Real-world theory example Application of each theory to virtual communication Social Exchange Theory Theory that attempts to explain human behavior in terms as behavioral psychology. The main principle of this theory is social relationships are the outcome of an exchange process with the purpose of maximizing the benefits and minimizing costs. An example of this theory is asking someone out on a date, but you dislike the fact that he/she lacks money or good looks, but he/she is caring and fun to hang out with the therefore you go because the benefits outweigh the cost. The rewards of virtual communication include freedom from the constraints of time and space but the costs is the possibility for misunderstanding when we are not able to see each other’s facial expressions or tone of voice. Systems Theory Systems theory is an open system of interdependent elements, employing input variables and process variables to yield output. The main principle is to receive input, process input and yield an output An example would be in a group you collectively develop a task from input and expect productivity as a output. Connection through the internet can alter patterns in many ways making the system more open. Symbolic Convergence Theory Theory of communication that explains how certain  types of communication shape a group’s identity and culture, which in turn influence other dynamics. Share group fantasies create symbolic convergence.  In a business symbolic convergence is used to determine what the customers like about the business and that allows the business to cater to the customer. In, virtual communication the possibilities for visual, verbal, or auditory communication can make new avenues for fantasy themes and group identity. Structuration Theory Theory that provides a general framework  and explains how people structure their groups by making active use of rules and resources. The main function of this theory is to focus attention on individuals’ behaviors in groups rather than on dynamics of groups. Basketball team is a example of structuration theory, because it has structure and rules that all members must follow. The coach is the leader and implements the rules for the team to follow. use of computers, e-mail,  and the internet as resources can expand the repertoire of structures available to group members. Functional Theory Communication in groups that functions to promote sound reasoning, prevent errors, and build relationships among all members. Focus on results and outcomes of group behaviors and structure. In a group where members use this theory to make decisions and to solve problems. Use of virtual group communication to enhance areas of group interaction by extending dialogue beyond a meeting room.

Gretel is twelve years old and she thinks she’s very smart, old and wise. Bruno is a little scared of Gretel. When Gretel becomes a little older, she gets more serious and stops teasing Bruno. Schmuel – Bruno Schmuel and Bruno are very good friends. In the end of the book, Bruno calls Schmuel his best friend. Bruno goes every afternoon to the fence to talk with Schmuel. They can’t play, because the fence separate them.Their friendship is also strange, because Schmuel hates all the soldiers who live with Bruno. Bruno doesn’t know what the soldiers (and his father) do to the Jewish people. Father – Bruno Bruno doesn’t really know what his fathers’ Job is. He only know his father wears the most beautiful uniform of all the soldiers. The year after Bruno went to the airtight room, his father goes back to the place where the clothes of Bruno were found.

Overpopulation: Earth’s Destruction

Amanda Broxton Instructor Sabel Composition II Cause and Effect Essay May 28th, 2009 Overpopulation: Earth’s Destruction Can you picture it? On one side of the world, in the middle of nowhere, a potentially beautiful child is just skin and bones; on the other side, another animal that can not be replaced has gone extinct. Somewhere there is a woman washing her few belongings in a dirty, polluted river. These and many other events like them are taking place all over the world. The cause? Over popularization, on which has been the root of many problems and is caused by many others, but do not worry there might be some hope in fixing it. Due to over popularization, one of Earth’s potential destruction is caused by over-production of the land. From more and more animals going extinct that can not be replaced because there isn’t room for them to live on. Also because of this, there is not enough food and clean water for humans and animals alike. Plus, humans are not conserving resources as they should and are taking prime land to pile more and more people on. Environmentalists have long been concerned about the resources threatened by rapidly growing human populations, focusing on phenomenon such as deforestation, desertification, air pollution and global warming. But the worst-case scenario for people experiencing overpopulation, according to Lawrence Smith, president of the Population Institute, is a lack of fresh, clean water. â€Å"If the water goes, t he species goes,† he said. ’(Hoevel, 2008, para. 9). Equally important is the fact that this is all caused by us Homo sapiens looking for a better lifestyle. We now have new medicines and technologies to help us live longer by healing every little thing that might be wrong with us. Some of those things were introduced by Mother Nature to kill us off to keep everything equal. We also have higher birth rates produced by more people having healthier births and multiple births. Furthermore, these children are living through earlier childhood killing diseases with the aforementioned medicines and technologies. ‘Until recently, birth rates and death rates were about the same, keeping the population stable. People had many children, but a large number of them died before age five. During the Industrial Revolution, a period of history in Europe and North America where there were great advances in science and technology, the success in reducing death rates was attributable to several factors: (1) in-creases in food production and distribution, (2) improvement in public health (water and sanitation), and (3) medical technology (vaccines and antibiotics), along with gains in education and standards of living within many developing nations. Without these attributes present in many children's lives, they could not have survived common diseases like measles or the flu. People were able to fight and cure deadly germs that once killed them. ’(Kinder, 2009, para. 10). Not to worry though, there are some ways that this inequality maybe reversed. They may not be what many people would approve of, but at least they are ideas of what we could do. That this one for instance, at the end of each month we would tally all the births. Then picking at random from those people that are on death-row or even in prison or jail for life for longer then ten years, would have the honor of helping with the equalization of the birth-to-death ratio. If nothing else, after a few years, this should deter hard crime. Each country and/or state would be responsible for The Equalization Program. There is also the idea of reinstating the two birth policy (China had this policy at one time) with a few ‘minor’ adjustments. One being that right after the second birth there would be a mandatory sterilization of the mother and father, and any other men over fifty years of age would also have to be sterilization. Those that wanted another child would then have to adopt those children that unfortunately don’t have a home. In conclusion, sure over popularization has many causes and it may cause many problems, but at least there are some solutions that can be looked at. I did not say that many people would like them but they’re there. In the end, I hope that things can be equaled out so that we do not have to put such a strain on our one and only earth. If we destroy it, there is not another one that we can start over on. Work cited

Japanese and centralization Essay Example | Topics and Well Written Essays - 250 words

Japanese and centralization - Essay Example However, in tandem with an understanding that centralization establishes and upholds a natural order, the piece also indicates that the â€Å"unsettled† minds of the people and the doubt that they have for the future is likely to create a significant hardship for any that would attempt to establish a further level of centralization or control over the territories. Likewise, the second document, entitled â€Å"The Capital, Taxes, and the Army†, written in 646 AD also compounds the importance and need for centralization. In such a way, the author focuses on the need to maintain a national army and the importance of subservience and loyalty that this army will have to the emperor. Yet, rather than focusing on how this could be established, the article returns to the competing interests of tribal warlords and those that might wish to have a disproportionately large say in the affairs of the newly created state. The undertone of the entire article is one that leaves the reader with little question that these types of individuals cannot be won over to the cause and must ultimately be coerced by force to engage in the process of centralization. Similarly, the third document, entitled â€Å"The Corruption of Local Officials†, focuses, not surprisingly, on the high levels of corruption being a stumbling block to further levels of centralization. With these local officials withholding money and tribute for themselves, the degree and extent to which a central emperor can raise taxes and have sway over a given region was obviously

Chemistry of Depression Essay Example | Topics and Well Written Essays - 1000 words

Chemistry of Depression - Essay Example Depression is mainly seen among females even though it is common among males also. Medical science was confused about this discrepancy in the occurrence of depression among males and females. However, recent studies have shown the reasons. â€Å"Scientists from the Karolinska Institutet, Sweden, showed that the brain's serotonin systems in males and females are different. They think they might have found one of the reasons why more women are affected with depression and chronic anxiety than me† (What Is Serotonin? What Does Serotonin Do?).Apart from Serotonin, dopamine, norepinephrine, melatonin, insulin and prostaglandins are some other chemicals which affect mood and emotions. Dopamine is also an aromatic compound in organic chemistry. It is a kind of neurotransmitter which controls the movement of emotional responses. Dopamine deficiency can cause not only depression, but also other disorders such as schizophrenia, Parkinson’s disease etc. â€Å"Pharmacological trea tments support the idea that an overactive dopamine system may result in schizophrenia: Medications that block dopamine receptors, specifically D2 receptors, reduce schizophrenia symptoms. The brain regions known as the thalamus and the striatum are affected by dopaminergic activity† (Gromisch).The neurotransmitter dopamine (DA) and the dopaminergic neurones play an important role in schizophrenia and Parkinson's disease (PD). A decrease in DA in the substantia nigra of the brain has been implicated as the cause of PD.
