Human Interactions with Nature in the Rocky Mountain States :: Native Americans Wilderness Papers

Human Interactions with Nature in the Rocky Mountain States Human interaction with the Rocky Mountain States has shifted tremendously since the beginning of recorded history. These changes can be broken down into three phases. The first phase would be the communal posture held by Native Americans. This period of time ran from the Spanish colonization in the 16th century until the era of the mountain man. With the establishment of the United States a new period of exploration for exploitation began. A dramatic shift in human interaction occurred as the economic interests of the mountain men and the United States overrode the communal interests of the Native Americans, indeed, it began to envelop them. The era of exploitation would flourish until the Progressive Movement. The first generation of leaders to see the footprint left by the over-harvest of natural resources would start the shift in policy to one of sustainability. This shift has continued at different rates of change all the way through the modern era. The Native American tribes of the American Rocky Mountain States were long characterized as being homogenous with little difference between them. In reality they are as diverse as European states, but like Europeans the religions that shaped their actions held a common theme. â€Å"[A]ll their religions had important characteristics in common†¦ the Indian visionaries felt the universe about them and dedicated themselves to keeping man’s world in balance with the cosmos... All of them sought to communicate with the powers of nature.† (Hurdy 14) The words of Hopi chiefs and elders, declared in 1951, are true for all tribes: â€Å"Our land, our religion, and our life are one.† (Martin 15) This communal living was sustainable and based upon the indigenous plants and animals, especially the bison herds which spread across the prairie like waves on an ocean. â€Å"Oglala Sioux spiritual leader Black Elk†¦ recalled that his people ‘were happy in [their] own country, and were seldom hungry, for then the two-leggeds and the four-leggeds lived together like relatives, and there was plenty for them and for us.† (Spence 3) Native Americans saw a special sanctity in taking anything from the earth. The Hopi Indians, for example â€Å"express[ed] regret to the hunted animal that they must take its life to sustain their own with the substance of its flesh.† (Hurdy 19) Ruth Underhill writes that the Naskapi saw â€Å"Hunting [as] a holy occupation†¦ [but] so was the gathering of plants, the cutting of trees, even the digging of clay.

social security Essay example -- essays research papers fc

In reading the book â€Å"Social Security and the Family† I learned a lot about the system that I had no idea about before. The book was fact filled and almost fun to read the need to know information. I gained much knowledge in the specifics of why the social security system is in need of reform, and why it will be inadequate in the years to come. One of the reasons our social security system isn’t working is because, â€Å"Social Security was modeled on the single-earner, married-couple family† (1). Times have changed dramatically since then.   Ã‚  Ã‚  Ã‚  Ã‚  When assessing the issues and current structure of the security system for change, â€Å"Four elements characterize the objectives of most tax expenditure programs, including Social Security† (179). A few of these issues are related to recent subjects addressed in class.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The first discussed is Income adequacy,† or the extent to which the program distributes more resources to those who are worse off than to those who are better off, typically measured by annual income. One important measure of the programs success in meeting this objective is its antipoverty effectiveness† (179). Since poverty is one of the main reasons for reform, this is a good issue to have been discussed.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The second is individual equity, â€Å"based on the idea that individuals should get what they pay for† (181). The problem with this issue is that many people are not getting back all they deserve.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The third discussed as in class is horizontal equity, â€Å"or the equal treatment of individuals in equal circumstances† (181). The idea behind horizontal equity is to give families with about the same earning... ...nts' card games to repeat the promise. He has brought along his mother, Barbara Bush, to show he understands older people's concerns† (NYT). This is just one of the many problems we face in trying to fix the system for now and in the long run for when its time for the younger generations to retire. Social Security and the Family† is a very well written book in addressing the under-funded System and other unmet needs. Being edited by three individuals who are Mellissa M. Favreault, Frank J. Sammartino, and C. Eugene Steuerle gives the reader three times the information about the system. The Setup and way the book flowed kept you reading through the ideas with ease. I would recommend this book to anyone and everyone because that is who the Social Security System affects. Works Cited New York Times. The New York Times Company. 2005   Ã‚  Ã‚  Ã‚  Ã‚  Anne E.

The True Eternal Love Is the Love of a Mother to Her Child

As of now I have not yet experienced to carry a child to my womb. But you know what? I already felt it. It’s really hard to be pregnant in times of troubles and problems. My sister experienced it. On that time, she had to move away from us because my mom didn’t want to see her. It’s emotionally hurting. I know how she feels, how they feels. Mom is hurting too. But I knew her. She will never show her weaknesses to others. On the other side, Ate is hurting. She is emotional because she is pregnant. That’s why I just supported her.I tried to make her smile every day I’m going to their home. Yes, I’m visiting them without mom knowing it. I’m bringing her a piece of mango every day, or sometimes oranges, or an apple. I want her to be healthy for the sake of the baby, too. It’s really happy to think that in that way, we became closer and closer to each other. Almost all the time her husband was on his work. That’s why I’ m the one coming with her at the maternal clinic every schedule. I felt excitement when I saw the baby’s first picture! The doctor told us there that it was a girl. She’s pretty. I knew it! =)She’s seven months on her mother’s womb when Ate took steps on the stage to get her diploma. Yes, she did continue studying to finish her course. It’s not our mom who walked with her but our aunt. Thanks to our lovable auntie because she helped us to convince mom to let Ate live with us again. I know she can’t ignore it. Why? Because she do loves us, Very much indeed. Dramatic scenario when the entire member of the family cried. That was a happy night to remember, when our family from being broken unite as one again. And that, there is one little angel will be added to the family.It was June then. The baby grew bigger at Ate’s womb. The doctor told her to stop eating too much. The baby is too big and might get bigger if she continues to do so. If that happened, it will be hard for her to give birth. June 15 was actually her due date but until the 25th of June came, she’s not feeling anything that indicates she had to confine. I suggested then to take her to hospital so that the doctors could give her drugs. The baby was excited to feel us. I felt it too. She’s moving almost all the time. And it is ridiculous that whenever I’m asking her to move, she will definitely do t! She can understand and hear me. It’s blissful! The day came. It was 30th of June and I was on my school. I called my mom by lunch time and she told me Ate was still laboring. I was so worried. I know it’s difficult for her. If you could only see Ate, she is thin and little! And imagine that big angel on her tummy! The only thing I can do is praying. Surprisingly by 3:40, I was on my home from school, my mom texted me that Ate had successfully gave birth to her baby. And about her name? She was named Criziah Wynes M. Agao. |Pretty cool, isn’t it?The next day they came home. Ate was sick and tired. I bet she got to confine. It might be a serious illness like the doctor told them before they leave. She can’t even take care of Wynes. That’s why I’m helping my mom to fix things needed for our angel. And as time goes by, by God’s will, we became okay and the family became big and happy. Now Wynes is one! And until now, I am one of her so called moms. She’s always calling me. She wants to come with me whenever i’m going to school. She wants me to be with her whenever they’re going somewhere.I almost live at their house because she wants me to sing a lullaby for her at her sleeping time. But ask me about the feeling. It’s very happy to be with her EVERY MOMENT. I’m not her mom, but I can feel she is mine. She is my pain reliever, stress reliever and my happiness. She makes me smile though I’m not well. She makes me smile thru bad ti mes. I’m not a mom. But Wynes let me experience and feel it. I also don’t believe in eternal love, I never before. But as of now, I just realize that aside from God’s eternal love for us, there is another one. And it is the love of a mother to her child. =)

Diagnosis and the Level of Traumatic Brain Injury

Diagnosis and the Level of Traumatic Brain Injury The subject of the case study under consideration is a 17-year-old Latina girl, Mary S, who is delivered to a hospital unconscious with a head bleeding freely as a result of an unsuccessful pool jump from the second floor. She is given PET scans that help to define a number of injuries and the necessity to be placed on precautionary life support.Advertising We will write a custom case study sample on Diagnosis and the Level of Traumatic Brain Injury specifically for you for only $16.05 $11/page Learn More The level of TBI has to be defined by means of the analysis of the results of three types of tests: the Glasgow Coma Scale, the duration of post-traumatic amnesia, and the duration of the unconscious state (Lezak, Howieson, Bigler, Tranel, 2012). As she follows the orders of a neurologist, opens her eyes briefly, moves her fingers, but is not able to speak just moan incoherently, the Glasgow Coma Scale demonstrates the results such as: E3, V2, and M6. The loss of consciousness lasts for about 3 hours. Amnesia is hard to observe as the girl does not respond verbally for about a day. The next day, she recognizes her parents. The interpretation of these elements proves that Mary has the moderate type of brain injury. The moderate brain injury usually causes brain swelling and bleeding as a result of which a person spends much time sleeping. At the same time, a person is not in comma and can be aroused (still, it is not recommended) (Brain Trauma Foundation, n.d.). Taking into account all information got and the evaluation of the DSM-V standards, the following diagnosis may be given: traumatic brain injury with the consequences like adjustment disorder with mixed anxiety and depressed mood (309.28 DSM code), posttraumatic stress disorder (309.81 DSM code), and disorder of written expression (315.2). A Pre-Morbid Estimation The estimation of pre-morbid functioning is one of the crucial steps that have to be done as when a TBI case takes p lace. As a rule, special tests like the NAART or WTAR are used to determine a person’s pre-morbid level of intellectual functioning along with the use of existing records (Strauss, Sherman, Spreen, 2006).Advertising Looking for case study on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More In the case study under analysis, it is stated that Mary has not passed through full-scale IQ tests, this is why the results of the tests are definite in regards to a particular situation. The WTAR (Wechsler Test of Adult Reading) on the basis of No-Child Left Behind Testing records is may be used with Mary as she meets its age ranges (16-89 years), speaks English perfectly, and can demonstrate her abilities to pronounce irregular verbs with a clear understanding of what they are all about (Strauss, Sherman, Spreen, 2006). The test lasts about 10 minutes during which an examiner presents 50 word cards one by one and gives promp ts to a patient on how to pronounce a word. Each correct answer is 1 score for the patient. In case 12 incorrect answers take place, the test has to be stopped. The peculiar feature of the test is the possibility to compare predicted and actual functioning considering the general intellectual status and the condition of memory. As soon as all 50 cards are shown, the results are evaluated in regards to the age of a patient. Mary is a 17-year-old girl with a high level of knowledge and abilities to work during classes. Her results are expected to be high indeed as she likes to study and achieve the highest grades in comparison to her fellows. Assessment of Mary’s Post-Injury Intellectual Ability The WAIS-IV is the test used on Mary to check out her post-injury intellectual abilities and define the possible deficits between her pre-injury performance and post-injury performance. The test consists of a number of stages that touches upon the girls’ verbal comprehension, wor king memory, perceptual reasoning, and processing speed (Strauss, Sherman, Spreen, 2006).Advertising We will write a custom case study sample on Diagnosis and the Level of Traumatic Brain Injury specifically for you for only $16.05 $11/page Learn More Mary came to the hospital to take the tests in time and demonstrated her desire to pass through the tests within a short period. She supported eye contact and was eager to answer all questions clearly. During the tests, she stayed calm and focused on the tasks, but she could be easily distracted by outside noise. Sometimes, it was seen that Mary was at a loss as she could not find out a correct answer as quickly as she used to. She liked to complete tasks before the deadlines, still, the results of the test proved that she could suffer from some deficits. WAIS-IV scores were as follows: VC (114): similarities 13, vocabulary 103, information 12; WM (100): digit span 10, arithmetic 10; PR (98): block design 10, matrix 910, symbols 11. In general, full scale IQ was about 105; general ability index was 106.Advertising Looking for case study on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More The evaluation of the tests and Mary’s reaction, it is possible to admit that her TBI associates with such deficits like short-memory problems, processing speed, attention functioning (she is unable not to pay attention to the distracting factors around), and social perception deficit (she wants to control the reactions of people on her behavior, but she cannot do it). The comparison of her pre-injury and post-injury performance proves that the girl has some problems with the perception of the world around and the inabilities to complete the functions she used to complete. She is upset and even angry with her inabilities to memorize simple facts mentioned recently. Assessments of Cognitive Speed Several tests, which are more sensitive, are used in order to determine why Mary cannot keep up in class. These are Trails AB, the PASAT, and Digit Symbol. As Mary was diagnosed with TBI, the tests under consideration should help to define the reasons of why she cannot concentrate on the details, be more attentive, and memorize information. The purpose of the Trail Making Test is to prove the presence of brain injury. Mary has to connect the 25 numbers chaotically distributed on a page. She begins properly, still, in several seconds, she starts making mistakes and stop completing the test. She does not want to continue. The part B of the test (the alternation between numbers and letters) helps to check out Mary’s visual motor abilities and visual spatial abilities. The results are the same: the girl does not want to finish the test due to her inabilities to focus on the task. She does not meet time limits as well. It proves the presence of TBI as well as the consequences such as anxiety and written expression. The PASAT test causes a number of problems as the use of a tape and the necessity to follow certain rules in a definite period of time make Mary dissatisfied and angry because of her inabilities to meet time deadlines and requirements of the test. S everal attempts are made to re-start the test, still, it also serves as a proof of a traumatic brain injury that causes a number of problems with cognition and behavior in general. Finally, the Digit Symbol test, that requires attention and time, calms Mary down and provides her with a chance to complete the task properly meeting all the standards. It shows that her cognition may undergo some improvements in case special conditions are provided. Recommendations for Accommodations and Rehabilitation The effects of brain injury turn out to be catastrophic for Mary. She refuses to attend school and talk to her parents about the problems that really bother her. Her injury harms her cognitive skills, memory, and concentration abilities. The results of these deficits are problems with reasoning and even vocabulary. She cannot keep up in class and suffers from fatigue and anxiety. This is why some accommodations in classrooms and rehabilitation at home are necessary for Mary. Accommodation s can be as follows: Provide with additional time for various class assignments; Support Mary with some teacher’s notes; Give her oral and written instructions; Allow her using notebook to check her spelling and grammar in cases of emergency; Reduce the rubric expectations in regards to the quality of the work done. Still, it is necessary to admit one fact – Mary may not want to be provided with special terms of education. This is why it is better to offer her some time for rehabilitation at home and use medical support to overcome the challenges of TBI. Rehabilitation details: Cognitive therapy focuses on the improvement of cognitive skills that can be relearned. It is possible due to certain repetitive activities, support of a professional, and clear explanations. Occupational therapy may be provided by advanced nurses and followed according to a properly developed health plan in a hospital. Neuropsychological tests should be considered on a regular basis as they can show the results of the therapies used. As soon as these hints are taken into consideration by Mary and her parents, she has all chances to get recovered and achieve appropriate results within a short period of time. A Prognosis Mary’s case is a tragic development of the events that cannot be predicted but may be improved. As soon as she is diagnosed with TBI with a number of consequences influencing the girl’s cognitive development, memory, and behavior, the test assessments, and evaluation of her reactions by the professional neurologists prove that Mary suffers from long-term TBI effects. She is in need of professional help and appropriate treatment at home as well as in a hospital. She has to be treated by an expert in order to re-develop her skills and be able to gain control over her emotions and inabilities. Mary has to be ready that she cannot perform all the activities at the same level as she used to. She needs to be supported by her family and her frien ds. In case these suggestions are followed, a prognosis of her recovery may be rather positive. Of course, people suffer from some problems after their TBIs. They need time and understanding. Mary’s status in a society she lives in should help her to find the required portion of support and continue living according to her ordinary style of life soon.

Essay Sample on Cloning A Satirical Approach

Essay Sample on Cloning A Satirical Approach Free example essay on Cloning: Family life in the new millennium is constantly changing. The number of mothers acquiring full-time employment is increasing, fathers are spending more time at the office and consequently their children are spending more time at daycare. Economist Michael Mitchell states his belief as to why this is happening, The costs of living as well as the current condition of the Canadian economy are both placing pressure on employed  Canadians – especially those with children  Ã¢â‚¬â€œ to spend more time in the office. The fear of losing ones job is just too great right now. But what about the effects this situation has on these families? In a recent country-wide survey of employed Canadians with children between the ages of 1 and 15, 91.2% of working women would like to be able to leave work early to see their children more each day. The survey also showed that the children who attend daycare spend on average 20.1 hours per week in that establishment. Another recent study conducted at the University of Toronto showed a strong correlation between the amount of time a parent spends relaxing, and the quality of their work and family life. Psycho-sociologist Fran Baker states that, when a person is able to take time from their busy schedule, and do something that they enjoy, it improves their attitude towards their job and helps to form a healthy family dynamic. Not only do the parents suffer a loss from this situation, so do the children. Carla Simons, from Brainy Babies Daycare Center in Etobicoke, believes, [e]ven though the BBDC is focused on helping these children develop healthy personalities and interpersonal relationships, it is still much better for them to learn these behaviours from their parents. All these children tell my coworkers and me how much they miss their parents; that must be an indication that something needs to change. It is clear that not only do the parents want to be with their children more, but the children want to be with their parents. But what could possibly be done to ensure the parents maintain their careers, spend more time with their children and still keep time for themselves? An idea that was farfetched until recently: getting a clone or maybe even two. One might be wondering how this is even possible. It is possible, and the process is not even too difficult. Once cloning becomes more popular, one will be able to go to their local cloning center to inquire about being copied. According to an in-depth interview with biotechnologist Abe Atkins, the steps are as follows: A sample of your cells, like skin or hair, will be taken. Doctors will take an embryo (unused from an In Vitro Fertilization clinic), remove the nucleus also called DNA from the egg, and combine it with one of your cells. Once they are combined, the embryo will now contain your DNA. The embryo is implanted in the uterus of the surrogate of your choice and 9 months later the clone is born. Some people have concerns about this process, so I, along with the knowledge I have gained from my friends in the cloning business, will clear them up. It has been said that some clones could be born up to two times larger than a real baby. For this concern, there are two options. One is that you could keep the giant clone to serve as a body guard. Imagine; you could finally feel safe walking through the streets at night knowing that you have a larger, more intimidating version of yourself protecting you. Or if your kids were going to be out late, you could send your clone along to be with them! If you do not feel as though you need a bodyguard clone, the giant could be donated to the Canadian army. We are sorely lacking in the defence of our country (which in itself is an entirely different article), so it would be a great help to your country if you would donate this super-sized being to protect us. It would be a warm, fuzzy feeling knowing how much you were contributing to the saf ety of your community. Some may be wondering if their boss or their children will know the difference between themselves and their clones. Of course there might be some slight differences in personality, but the clone could easily be trained to perform all the necessary tasks and interpersonal skills of the workplace, and also the general ideas of parenting. The parenting skills should only be used if one was in need of a babysitter, as it is strongly believed by all advocates of cloning that the real parents should be raising the children. As well, one would have to decide what their children would call the clone. Some suggestions from researchers in cloning labs are Clonimommy and Daddydouble. For those times when one would like to be the only one of themselves in public, special clone-chambers can be installed in your home for easy storage. Not to worry, clones are not real people and do not need to be given attention all that often. Others do not need to know you have a clone, and clones certainly do not have to be high maintenance. The last major concern that should be addressed is clonal reproduction. Abe Atkins has reassured everyone that, [n]o clones will have the ability to reproduce. These beings are not real people and by no means have the right to create children of their own. For this reason, they will all be sterilized at birth. This is a good thing; Canadians certainly do not want little clones to take over the country and maybe even lower taxes. When addressing the many concerns, I do not mean to say they are not legitimate, however they in no way compare to the advantages that come from cloning. The best advantage would be that parents can spend less time in a stressful, pressure-filled environment, and spend more time in a relaxed, happy environment spending quality time with their children. The clone will continue bringing in an income and furthering your career, while you can raise your standard of living in a non-financial way: by keeping your children out of daycare and forming healthy relationships within your household. When not at work, ones clone can take care of all housework and other errands that need to be done especially cleaning the toilet and picking up after the dogso that one can have time for oneself. One could take the time to read a book, take a bath or go to the gym. This would mean that people would be less stressed, happier, and be healthier both mentally and physically. Speaking of health, clones could also be grown and stored for the purpose of having extra organs in the case of an emergency. As Canadas healthcare is also on the rocks, there would no longer be a wait for an organ, and there would be no risk of rejection once the transplant was completed. As mentioned previously, a great advantage to cloning would be the increased enrolment in the Canadian army. Maybe our new strength in numbers would lead to a spot of respect or even true acknowledgement from the United States! This article is in no way saying that every person should get a clone. It is however, an option for the many Canadians that are in the conflicting situation of having a career, having children, and at times just need to be in two places at once. Many would say that cloning should never be an option, and to do so without enough experience and knowledge of the effects of such an action is completely irresponsible. These clones would be real people, and their feelings as humans need to be considered too. Although this article has supported the idea of cloning, I can in no way benefit from this technology. I have no wife, no children, and the leisurely job of writing childrens pop-up books at my home in a little known town in Spain.

Elephant Toothpaste Chemistry Demonstration

Elephant Toothpaste Chemistry Demonstration The elephant toothpaste chemistry demonstration is a dramatic demo which produces copious amounts of steaming foam that sort of looks like the toothpaste an elephant might use. Heres how to set up this demonstration and a look at the reaction behind it. Elephant Toothpaste Materials The chemical reaction in this demonstration is between the hydrogen peroxide and the potassium iodide solution. The detergent captures the gases to make bubbles. Note the hydrogen peroxide solution is much more concentrated than the kind you can buy at a pharmacy. You can find 30 percent peroxide at a beauty supply store, science supply store, or online. 50-100 ml of 30% hydrogen peroxide (H2O2) solutionSaturated potassium iodide (KI) solutionLiquid dishwashing detergentFood coloring500 mL graduated cylinderSplint (optional) Safety Wear disposable gloves and safety glasses. Oxygen is evolved in this reaction, so do not perform this demonstration near an open flame. Also, the reaction is exothermic, producing a fair amount of heat, so do not lean over the graduated cylinder when the solutions are mixed. Leave your gloves on following the demonstration to aid with cleanup. The solution and foam may be rinsed down the drain with water. Elephant Toothpaste Procedure Put on gloves and safety glasses. The iodine from the reaction may stain surfaces so you might want to cover your workspace with an open garbage bag or a layer of paper towels.Pour ~50 mL of 30% hydrogen peroxide solution into the graduated cylinder.Squirt in a little dishwashing detergent and swirl it around.You can place 5-10 drops of food coloring along the wall of the cylinder to make the foam resemble striped toothpaste.Add ~10 mL of potassium iodide solution. Do not lean over the cylinder when you do this, as the reaction is very vigorous and you may get splashed or possibly burned by steam.You may touch a glowing splint to the foam to relight it, indicating the presence of oxygen. Variations of the Elephant Toothpaste Demonstration You can add 5 grams of starch to the hydrogen peroxide. When the potassium iodide is added, the resulting foam will have light and dark patches from the reaction of some of the starch to form triiodide.You can use yeast instead of potassium iodide. Foam is produced more slowly, but you can add a fluorescent dye to this reaction to produce elephant toothpaste that will glow very brightly under a black light.You can color the demonstration and make it into an Elephant Toothpaste Christmas Tree for the holidays.There is also a kid-friendly version of the elephant toothpaste demo that is safe for hands. Elephant Toothpaste Chemistry The overall equation for this reaction is: 2 H2O2(aq) → 2 H2O(l) O2(g) However, the decomposition of the hydrogen peroxide into water and oxygen is catalyzed by the iodide ion. H2O2(aq) I-(aq) → OI-(aq) H2O(l) H2O2(aq) OI-(aq) → I-(aq) H2O(l) O2(g) The dishwashing detergent captures the oxygen as bubbles. Food coloring can color the foam. The heat from this exothermic reaction is such that the foam may steam. If the demonstration is performed using a plastic bottle, you can expect slight distortion of the bottle from the heat. Elephant Toothpaste Experiment Fast Facts Materials 30% Hydrogen PeroxideConcentrated potassium iodide solution OR packet of dry yeastLiquid dishwashing detergentFood coloring (optional)Starch (optional) Concepts Illustrated This demonstration illustrates exothermic reactions, chemical changes, catalysis, and decomposition reactions. Usually the demo is performed less to discuss the chemistry and more to raise interest in chemistry. It is one of the easiest and most dramatic chemistry demonstrations available. Time Required The reaction is instantaneous. Set-up can be completed in under half an hour. Level The demonstration is suitable for all age groups, particularly to raise interest in science and chemical reactions. Because the hydrogen peroxide is a strong oxidizer and because heat is generated by the reaction, the demonstration is best performed by a science teacher with chemical experience. It should not be performed by unsupervised children.

Ethics and Corporate Responsibility in the Workplace and the World Term Paper

Ethics and Corporate Responsibility in the Workplace and the World - Term Paper Example The end use customers of the products offered by the company are also stakeholders who are impacted by the operations of the company. It can also be seen that the regulatory authorities who oversee the operations of the company are also regarded as the other stakeholders in this particular case. 2. The concept of ethics is primarily concerned with differentiating between something that is good from bad (Robbins, 1993). By any standard, it can be seen that the conduct of PharmaCare in Colberia is unethical as a result of the fact that the indigenous population is treated in a bad manner compared to its executives. First and foremost, it can be seen that the healers in this area have volunteered to give their knowledge for free whilst the company is generating lots of revenue from this practice. The other issue is that these indigenous workers work for only $1 per day and they walk for five miles into the jungle to harvest the plants required for manufacturing medicine. These indigenou s people also carry heavy loads on their backs which can weigh as much as 20 pounds. The other issue of concern is that the indigenous workers live in primitive huts that do not have electricity or running water. Overall, the activities of the company in Colberia have destroyed the habitat in the area as well as endangered native species.
