Teachers and Why We Go to College

...the first teachers we have in our lives in most cases are our parents. They teach us to walk, to speak, and to have good manners before we reach "the real world." More than even the professional teachers that we have in school, parents are generally the most involved in the development and education of children. Almost for sure our parents are the best teachers at the beginning of our lives, which actually corresponds to the parents' role in nature. Parents are most committed and involved in teaching their children; they have a kind of instinct to sacrifice a part of themselves for the betterment of their children. They love us and have great patience while passing down their knowledge to us. They wish us a success and thus will not teach us bad things. And of course, implicit learning occurs when children unconsciously copy some of their parents' habits and styles of behavior. During the second stage of child development, adolescence, parents can still be in the best position to offer advice even though the children might not accept it. In this case, perhaps the child's friends would be the best teachers. Adolescents are notoriously rebellious in many cultures and may automatically reject any advice from their parents. My first marriage for instance, was solely a matter of doing the opposite when my parents tried to intrude in offering their advice. So in such matters, parents should be much more flexible and be rather the partners with their children. So we can see that......

Should We Go Beyond the Law

...alternative solution is to dump their waste into the river which will give them more savings. It is mention on the book that this alternative solution is good since there are some changes when it comes to environmental regulation. In this case, we can assume that the company’s expenses before and too high due to some environmental regulations that they need to follow. 4. Development of Alternatives The company can stick to the initial plan which is to throw their waste into the river in order to survive in their financial crisis. The company can still pursue the number one alternative and at the same time they should develop a product later on which will be an alternative of not throwing their waste into the river and later on do a campaign on how they can revive the river. Since the cause of its pollution came from the company. . 5. Selection of Desired Alternative The company can go to the second alternative, since a lot of employees will lose their jobs if the company will not survive as a short-term solution they can pursue the idea of throwing the company waste into the river. Of course, the action of the company is not good per se but we need to give importance as well to the big number of employees that will be lay-off in case the company will not survive. Once the company was able to get back on track with their first move, the company should do the next......

...organization to help children with maltreatment. The purpose of child protection services is to help protect children from physical abuse, neglect, emotional abuse, and sexual abuse, and to help families get the services for their children’s needs. Strength of the Public Health approach is its focus on primary prevention and education and its emphasis on the health not only of individuals but of families, communities, and society. The weakness on “Promotion of Children’s Rights and Prevention of Child Maltreatment” is the difficulty of using human rights approaches inside the U.S. and their strong focus on state responsibility. While laws and enforcement policies do need to change, even if the U.S. would recognize its own human rights violations we as a nation do not necessarily see the state as the primary means for ending child sexual abuse. A weakness in this article is the use of isolation of family violence from broader backgrounds of economic or cultural stress and the difficulty many family violence services continue to have in identifying and responding to child sexual abuse specifically. In conclusion, the emotional scars of both types of maltreatment are often deep and no child deserves to be maltreated. While most of us want nothing but the best for our children, child maltreatment are too common. While the words abuse and neglect are often used interchangeably, each type of maltreatment is distinct. Abuse is the intentional maltreatment of a child and can be......

...into their preferences, a broader creative palette to work with, and additional data and metrics to study. Yet there are unsolved questions over how best to organise and execute digital and social campaigns. No single formula ‘People find it hard to realise marketing is a two­way conversation rather than a one­way pushing­out’ has emerged, leaving most companies and ad agencies in a state of constant experimentation. There is also lingering confusion over how best to measure the effectiveness of a campaign, and a company’s return on investment. Ann Lewnes, chief marketing officer of Adobe, the software company, says she pushed the company into digital and social marketing early on. “We saw the insights we could glean from customers, the iterations we could do on a campaign,” she says. “We saw the ability to really, really measure results.” Adobe now spends 74 per cent of its more than $100m marketing budget on digital. Even for a digital-first company such as Adobe, each campaign is a fresh start of sorts. Ms Lewnes says 20 per cent of her budget is going towards experimental campaigns, and that each product launch requires a different mix of paid, earned and owned media. Perhaps the largest shift in recent years has been the transition from the one-way, broadcast messaging of television, print and outdoor, to the twoway conversation that social options now allow companies to have with their consumers. “It requires a shift in your perception,” says Maryam Banikarim,......

The Things That We Go

...David Coccoli Ms. White English 2 CP 12 January 2013 Dear Student, Have you ever been unprepared for a big test? From personal experience I can tell you that it is not something you want to experience yourself. I have encountered this a few times throughout school. I can tell you a few things I was able to do to prepare, the reasons I did not get to prepare as much as I wanted, taking the test, and things that happened after I completed the test. Hopefully you will learn from my mistakes. Some of the things I was able to do to prepare was go over it in class, make a foldable, and look over my notes right before I took the test. Just by going over the material in class, I was not fully paying attention. When I made my foldable, I copied off of someone’s so I could finish mine. Right before the test I just glanced over my notes. Those three preparation techniques are not recommended. The reasons I did not get to prepare as well as I wanted were because I was out of school with the flu. Therefore one of my friends William let me barrow his foldable, so I just copied it. While taking the test, I soon found out how unprepared I really was. Another thing that I found out was study only the night before a test isn’t a good idea. The reason for that is that you will not remember everything you tried to cram in your brain the night before. Whenever I got my test I completely froze up and couldn’t remember a thing on it. I would say I learned the hard way. After taking......

We Can, but Should We?

... We Can But Should We? Dara Shalom Chamberlain College of Nursing NR361-65561: Information Systems in Healthcare March 2013 We Can But Should We? “As healthcare embraces technology to improve patient outcomes, streamline operations, and lower costs, the technologies with the most impact are the ones that make things simpler” (Why and How). Various companies are trying to simplify the process of obtaining essential patient information with the use of quick response, or QR codes. These codes are placed on stickers, bracelets, and cards for wallets. When paramedics scan the QR code, they gain access to the patient’s health profile, which contains basic personal information, allergies, medications, and emergency contacts. With instant access to this vital information, medical errors are reduced, and the time that they would otherwise spend obtaining this information is cut. Some people believe that this is a wonderful advancement, and it “could benefit so many folks” (Davis), while others are concerned and skeptical about this new technology. Benefits One advantage of utilizing QR codes in emergency response situations is the shortened time spent obtaining vital patient health information. By cutting down time, paramedics are able to make treatment decisions more quickly. “Every second counts during medical emergencies, and quick access to medical information can be the difference between life and death” (Rich). Immediate access to the individuals medical......

Why We Shoud Go to Mars

...Why We Should Go to Mars Kenneth C. Brown II Why We Should Go to Mars Richard, an author for the website GOVTEEN Global Community, wrote an article briefly explaining why we as a nation, should not go to Mars. Some of the key points of his argument against going to Mars stressed that the financial cost would be too high, it would require several new spacecraft and ground habitats, and several new technologies that currently do not exist. He also was concerned about the budget cuts that have already stripped the National Aeronautical Space Administration (NASA) to a shell of what the space program used to be. He also stressed that we are still in an armed conflict that has put a strain on our nation, economically and emotionally. Richard's points are solid and very good. I agree with him mostly. However, I feel that for most of the points he states is actual the reason we should go to Mars. In the 1960's and early 1970's America was in heavily entrenched in the Vietnam War, the American people were divided, with a large potion severely frustrated with their government. The nation was also still suffering from racism, the assassinations of Martin Luther King Jr, President Kennedy and his brother Robert Kennedy. The Nation needed a positive focal point, a beacon to turn to remind them that even in those dark times there was something in their nation to rally behind, and lift their spirits. NASA became that beacon. The 1960's and 1970's saw the space program......

We Are What We Choose

..."We are What We Choose"
Remarks by Jeff Bezos, as delivered to the Class of 2010
Baccalaureate
May 30, 2010 As a kid, I spent my summers with my grandparents on their ranch in Texas. I helped fix windmills, vaccinate cattle, and do other chores. We also watched soap operas every afternoon, especially "Days of our Lives." My grandparents belonged to a Caravan Club, a group of Airstream trailer owners who travel together around the U.S. and Canada. And every few summers, we'd join the caravan. We'd hitch up the Airstream trailer to my grandfather's car, and off we'd go, in a line with 300 other Airstream adventurers. I loved and worshipped my grandparents and I really looked forward to these trips. On one particular trip, I was about 10 years old. I was rolling around in the big bench seat in the back of the car. My grandfather was driving. And my grandmother had the passenger seat. She smoked throughout these trips, and I hated the smell. At that age, I'd take any excuse to make estimates and do minor arithmetic. I'd calculate our gas mileage -- figure out useless statistics on things like grocery spending. I'd been hearing an ad campaign about smoking. I can't remember the details, but basically the ad said, every puff of a cigarette takes some number of minutes off of your life: I think it might have been two minutes per puff. At any rate, I decided to do the math for my grandmother. I estimated the number of cigarettes per days, estimated the number of puffs per cigarette...

...Globin = protein portion β2 β1 Heme group Binds O2 α2 α1 Hemoglobin consists of four polypeptide chains, 2 alpha and 2 beta, each of which contains a heme group. Each heme group is composed of a porphyrin ring with an iron atom at its center. The iron atoms each bind to an oxygen molecule. They can also bind to carbon monoxide. 11 Reaction at each heme group: Hb + O2 lungs tissues HbO2 deoxyhemoglobin oxyhemoglobin Hemoglobin saturation = % of iron atoms carrying an oxygen molecule. 98% saturation in oxygenated blood at sea level. Oxygen transport: 98% as oxyhemoglobin 2% dissolved as a gas in plasma The binding of iron to oxygen is a reversible reaction which is determined by the concentration of oxygen, the pH, and other factors we will discuss in more detail later. Iron will also bind to carbon monoxide (CO) in competition with oxygen. The strength of the bond with CO (called carboxyhemoglobin) is about 10 times that of the bond with oxygen. CO comes from polluted air resulting from incomplete combustion such as autos, woodstoves, etc. Removal of CO requires breathing clean air, or high concentration oxygen, or being placed in a hyperbaric (high pressure) chamber of pure oxygen. 12 Carbon Dioxide Transport 7% dissolved as a gas in the plasma. 23% attached to amino acids on globin – called carbaminohemoglobin. 70% reacts with water. Carbon dioxide is transported in three ways as shown above. The majority is the third way. The result of its reaction with......

...Culture and Business Management We all tend to have a management style which has evolved during our working life and with which we feel comfortable. Bear in mind, however, that your management style is probably heavily influenced by your country of origin. Different countries tend to develop different approaches to management and corporate structure. Some people are comfortable with the concept of hierarchy; others are not. Some people see managers as mentors who are there to encourage and coach; others expect a more instructional approach from the boss. When working in a multi-cultural environment you need to be aware of: * Your personal style and how this may be viewed by people from other countries * The expectations of other cultures with regard to how they expect to be managed * The need to communicate your own approach to working so that your international colleagues or clients are not left feeling confused and unsure of your intentions How will decisions be arrived at within your team or sphere of influence? Will the boss make the decisions and then issue instructions or will a more consensus-style be developed in which all group members are encouraged to participate in the process? Whichever style is adopted it is imperative that the process is understood by everybody from a very early stage in the life-cycle of working with people from other cultures: Interactions with a multi-cultural dimension work most effectively when: *......

Where Do We Go Now Respone

...Where Do We Go Now? At the end of the film Where Do We Go Now?, the Christian and Muslim women of the village swapped religions overnight leaving the men confused on to what was going on. While men struggled with this decision, the women carried about regular duties as if nothing had changed in their village. After this abrupt shift the men were on the way to bury Nassim, but when they got there, they were stuck trying to figure out which side to put him on, Muslim or Christian. Since the women of the village switched their religions, the men were uncertain as to whether or not Nassim, a Christian, should be buried in the Muslim or Christian side, leading the men to turn around in unison and ask the women “where do we go now?”. This was a really funny way to end the film, and also unexpected. It went from a serious moment, the funeral/ burial, to the confusion of the men of the village. The ending of the movie called for an alternative society in which there are no divisions among the villagers which is demonstrated through religious status. When the men were trying to figure out on which side to bury Nassim, I was thinking why they don’t just put him in the middle, where there would be no difference between Christian or Muslim. This is exactly what the women were trying to do throughout the entire movie and finally accomplished by switching from one religion to another, they wanted the war between two religions to end. This swap in the religions puts......

We Cannot Go Back - Gmo Paper

...,We Cannot Go Back It is inevitable, everyone has done it. It is as much a part of the human condition as any of life’s endeavors. As in the poem I Go Back to May 1937 by Sharon Olds; we sometimes explore the idea of altering our fate through changing the past. What if we could change our fate, or even just ensure a better future for your off-spring? Each of us possesses genetic material that is built upon a code that makes every organism unique. The technology to alter our genetic make-up is getting closer by the minute. I am referring to The Human Genome Project. What is a genome and what is this project you ask? The National Institute of Health or NHI defines a genome as: A genome is an organism’s complete set of DNA, including all of its genes. Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus. Basically, it is a map of how our DNA is assembled. DNA is a compound that is and the NHI gives this definition of DNA, “DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA.” There are four kinds of DNA and depending on how they are arranged, defines your genetic make-up. This arrangement forms a map of sorts, and this map is the genome. Ever since DNA was discovered in 1953, scientists have wanted to make the human......

Why We Should Not Go to Mars

...Why we should not go to the Mars Launching a manned mission to Mars has been a dream or substantial matter for the scientist throughout this decade. This idea has been argued by certain groups of people with supporting or opposing view. The trip to the Mars planet had facing a lot of problems or issues which need to overcome in order to continue this mission. Some of the supporting parties may argue that the exploration of Mars gives us a better understanding to our homeland, the Earth. They are also in the view where a manned mission to Mars may retain the leadership of United State of America in international space technologies. However, by gaining great reputation through leading the technologies in the world, the budget should spend in a more suitable way for economic or technical growth. Although there are certainly good arguments to send manned flight to Mars, I believe that there are more benefits sending unmanned probes to explore the planet than spending a huge amount of money in sending the manned flight over there. The supporters argue that by sending manned flight to Mars, we gain a chance to understand the Earth better due to the similarity between Mars and Earth. Hence we can figure out ways to protect the environment on Earth by exploring the condition on Mars. But the unmanned probes in this century are advance enough to pursue accomplishment in exploring different planets such as discovering the evidence of water on Mars. There are plenty more unmanned......

Jennifer Go-Go

...Case Study 1 1. How should Jennifer go about making her decision? Jennifer should evaluate each proposal and use criteria that will fairly indicate what project would be best to invest additional money in to for future growth and savings. She can use project selection and develop a set of criteria against which the project will be evaluated, list assumptions that will be used as the basis of the project, gather data and information, and evaluate each project against the determined criteria. 2. What kind of additional data or information should she collect? I believe that she should request information or data regarding the scope, schedule, cost, and customer satisfaction expectations of the projects and their goals. I have explained each below for better understanding. Scope – All the work that must be done to produce all the project deliverables that meet the customer requirements and acceptance criteria and accomplish the project objective. Schedule – A timetable for a project indicating when activities are planned or need to be started and finished. Cost – The overall cost it will require to complete the project in its entirety. Customer Satisfaction – After the project has been completed the customer feels as if they have received the services expected and the project was completed to their standards and expectations. However I know these can be considered restraints and that should be a heavily weighed factor in the decision making in the end. 3. What exactly......
