Interaction between Humans and the Environment Essay

Interaction between Humans and the Environment The relationship between humans and the environment has changed over time because of technological advancements and innovations. During the beginning of human time the people was mainly nomadic; they hunted for food and travel around in packs. Fast forward a couple centuries the interaction between humans and the environment changed from being primarily hunting and gathering to being primarily farm heavy. Lastly in the twentieth century the relationship between humans and the environment has changed due to industrialization which led to humans exploiting the environment and polluting it. At the beginning, everyone was nomadic roaming from one region to the next scavenging for food, because of the lack of technology. It wasn’t until the first Agriculture Revolution occurred that the people change their lifestyle. The agriculture revolution led to the change in human lifestyle. For example: people began to settle down, start farms, and start to live by water sources so they could irrigate the land in order to farm. The Agricultural Revolution also sparked the domestication of animals and plants allowing a large amount of food to be produce at any time. This led to a larger population and eventually led to the Industrial Revolution. The Industrial Revolution was when the interaction between humans and the environment turned sour due to the exploitation of the environment for natural resources. The Industrial Revolution caused imperialism which was regions being colonized for their natural resources. This was one of the causes of the World Wars, which was the war of attrition – the fight for natural resources. The wars caused a lot of pollution and the war also caused a lot of natural resources to be used to fight it. But in the modern day there are many â€Å"green† projects that we used in order to preserve our natural resources and save the environment.

The results are in! Resume Format Rundown

The results are in! Resume Format Rundown Last week I introduced you to Loft Resumes, a service that provides custom-designed resumes to job seekers in a variety of industries. I also provided sample formats from some of The Essay Expert’s successful resumes. I then asked you to vote on which you preferred. Here’s what the survey looked like for those of you who missed it   Id still love your input! Create your free online surveys with SurveyMonkey, the worlds leading questionnaire tool. Thank you to the 25 people who responded to my survey! Here’s the tally: Do you prefer the designs of Lofts designs or The Essay Experts? 1 person preferred Loft Resume’s designs. [This person was in the insurance industry] 17 people (68%) preferred The Essay Expert’s designs. 1 person liked both equally. [This person was in the IT industry. Note that The Essay Expert has some   other formats you might like better!] 1 person did not like either one. [This response came from an attorney. I agree none of the formats presented would be appropriate for an attorney. For attorneys we use much more straightforward designs.] 5 people chose â€Å"Other† and provided the following feedback: ATS Concerns Essay Experts designs are better, but I fear the inserted box and other graphics might skew an Applicant Tracking System preventing the information from being read and stored, costing an applicant the job by not registering properly within its system. If physically scanned, the Essay Expert is more professional and provides information employers want. [from a career professional/resume writer] My response: It is true that text boxes and graphics can skew an ATS system. After posting my article, I was contacted by a representative of Loft Resumes who stated that their resumes do well in Applicant Tracking Systems as well. I would have to test a resume myself to know if that is an accurate statement (Loft does not advertise that their resumes are ATS-friendly). Keep in mind that every job seeker must have TWO resumes: one for the computer robots and one for humans. Hiring managers, in my experience, really love The Essay Expert’s resumes. I do not have any information on their response to Loft’s designs. Too Dense I dont like either one, they are both too dense with info, the eye doesnt know where to go to quickly pick up the pertinent details. [from someone in the High Tech industry] My response: Thanks for your feedback. Thankfully the hiring managers who looked at The Essay Expert’s resumes appreciated something in the resumes, since both of these candidates got job offers for their targeted positions! Neither was in High Tech, and we would certainly use a different format for a high-tech position. Industry-Dependent Design It greatly depends on the industry/position. If in creative industry would prefer LOFT.   AND I think Lofts resumes are a little too designy the design has more impact than the information contained within it. But Lofts could be very good for people in the arts, film production, etc. My response: In fields like marketing and sales, you might be right that LOFT resumes could be viewed more favorably. In a field like graphic design, of course, it would be preferable for the candidate him or herself to design the resume! Its position AND audience specific. My response: I couldn’t agree more. We use different looks and feels for every industry we work with. As stated above, if the audience is a hiring manager a highly formatted resume is generally viewed favorably; recruiters hate them. Even The Essay Experts samples here might be too â€Å"fancy† for an accountant, although two responders in Accounting and Finance stated they were very likely to purchase an Essay Expert resume and very unlikely to purchase a LOFT resume. One responder whose industry is aerospace/defense wrote, â€Å"The Loft’s [formats] would never work in my industry.† And I received one response from a person in â€Å"consulting† who stated he or she would be very likely to purchase from The Essay Expert and very unlikely to purchase from Loft. I like LOFT designs for their uniqueness. They are probably appropriate for someone in more in a creative field versus an executive position. I like Essay Experts designs for their clean, uncluttered appearance. They are easy to read and probably more scannable than the LOFT design. My response: Thank you! I believe I addressed this comment above. â€Å"How likely would you be to purchase a resume design by Loft Resumes, The Essay Expert, or Another Service?† Overall, my readers (who I admit might be predisposed toward resumes by The Essay Expert) are much more likely to purchase a resume designed by The Essay Expert than they are to purchase a resume from Loft or another service. It was also striking to me that 50% were very likely or somewhat likely to purchase a resume from The Essay Expert. A gift to you! Thank you for your support, and if you responded to this survey and are considering purchasing a resume package from The Essay Expert, I will be happy to offer you a 20% discount on any package (maximum discount $100), offer good through April 30, 2012. Note you must complete the survey to qualify for this offer! This is your reward for being a loyal reader and participant in my interactive media opportunities and for reading to the end of this lengthy article! Category:Resume TipsBy Brenda BernsteinApril 16, 2012 2 Comments Rebecca Robin says: April 26, 2012 at 3:39 pm I did not find Preptel to be particularly valuable. For another opinion, I shared the site with a friend who is the head of recruiting for a 900 employee organization. She agreed. While the concept is wonderful, the execution leaves much to be desired. Many of the suggestions to improve keyword matches were nonsensical and words that were important matches were ignored. For example, the program missed the term CAD (computer aided design) but picked up plan and lost the connection between them both. A site I do like is wordle.net, but I use it to get an impression of what words are used most frequently in a job description. I might exchange the words highlighted in wordle with those in my resume to get a closer match. Thank you for your posts, I find them quite helpful. Log in to Reply The Essay Expert says: July 17, 2012 at 4:14 pm Thank you for your comment Rebecca. The issue is that of companies who use ATS systems, about half of them enter the desired keywords by hand, thus making sense to a human, and half let the computers determine the keywords. For that second half, unfortunately the keywords are often non-sensical. Thats why a program like Preptel can be useful! Im glad you are getting value from my posts and appreciate your feedback!

Enzymes Lab Report Essay Example

Enzymes Lab Report Essay Example Enzymes Lab Report Paper Enzymes Lab Report Paper The size, the smell, the color? Most of us WOUld have to say that if they grabbed an apple that had a bruised body, they would return that apple to the pile in search for that perfect skinned apple. This is why studying catechist oxides is so important! Lets take a look at population numbers and why catechist oxides is so important with the increasing number of people living on Earth. In 2010, the global population was estimated to be around 6. 9 billion people (1). From 2008 to the end of 2011, the number of hungry families in Washington grew from about 88,000 to 163,000 In 2011, 15. Percent of Washington households reported some level of food insecurity, which means they regularly struggle to get enough food for their families, according to the USDA. (2). With an increase like that in the amount of people struggling to feed themselves, how do we think its going to be when the expected population growth on Earth jumps to 9. 6 billion in 2050 (1)? This is why studying catechist oxides is so important. According to a UK news article back on September 19, 2013, Up to two-fifths of a crop of fruit or vegetables can be wasted because its ugly Produce grown in the UK that does not meet detailer standards on size or shape or is blemished is often used for animal feed or simply ploughed back into the ground even though it is edible, with as much as 40% of a crop rejected. (3). Up to 40%! With people going hungry all over the world, if we were able to figure out how to reverse catechist oxides or even halt it for a period, we would be able to have those fruits and vegetables out longer with purchasers willing to buy them because they still hold their pretty appearance. Before I get into more about the actual experiments done in the lab, let me explain in a little more detail about enzymes. Enzymes speed up chemical reactions and those chemical reactions then either consume or change the enzyme itself. Enzymes structures are three-dimensional that are built up by at least one or more peptide bonds that form what is known as an active site. The active site is where the substrate (catechist in this experiment) will go and attach. Many things such as changes in temperature and changes in pH can affect the structure of the active site which will affect the rate of reaction of how the enzyme contributes. Please see below for the chemical reaction done by catechist oxides: (4) This reaction is what causes the fruits and vegetables to brown or looked bruised. In the middle you see where the catechist oxides (remember: it is the enzyme so that means it speeds up the reaction) comes into play. Catechist oxides are found in the cytoplasm of the fruits and vegetables. When catechist oxides is exposed to oxygen, it turns the fruits and vegetables brown. Remember how above I stated that many things can change the structure of the active site, such as pH? Well as it would have it, all enzymes are affected by changes in PH. Not only can it change the shape of the structure of the enzyme, UT it can also change the shape or charges of the substrate as well. That can make it so the substrate is unable to bind to the active site making it unable to go through catalysis. So they work in whats called the lock and kef manner with the substrate. When the optimum pH level of an enzyme is met, it allows it to lock with the substrate to form the catalyst. The optimum pH is where the enzyme is the most active. But just because one enzyme is most active at a certain point, doesnt mean that other enzymes are the same. In fact, the optimum pH can differ greatly from enzyme to enzyme. Please look to the left for what optimum pH will look like on a graph (5). As you can see, at the highest point of the bell curve is where the optimum pH of that enzyme is. The optimal pH allows the reaction between the enzyme and substrate to continue on. My hypothesis for this lab, Exercise C: Effect of pH on the Action of Catechist Oxides: The rate of the catechist oxides activity levels will be altered by the change in pH levels. I believe this is so because as stated above, pH has a great effect on the structure and function of the enzyme itself. The rate of absorption will tell me whether my hypothesis is correct or not. My null hypothesis for this lab, Exercise C: Effect of pH on the Action of Catechist Oxides: The rate of the catechist oxides activity will not change due to the different pH levels. Rather it will stay the same throughout. Methods: was in a group of four people: Kari Serial, Kelsey Heinz and Deborah Thermal. For our Lab 4 Enzyme activities, we were going to be using potato juice (enzyme) and catechist to resemble the natural acting potato and catecholamine reaction. We followed Exercises A B as instructed in the Lab Manual for Lab 4 Enzymes. When it came to Exercise C, we were assigned pH. In order for us to be able o get all the information down, we split up the tasks for this exercise. Deborah and myself were the readers and recorders of the absorbency rates. We used a blank tube to get the absorbency level at 0 on the spectrophotometer at 0 seconds to get the experiment off correctly. Kelsey was the person who would take the test tube in and out of the spectrophotometer on Saris instruction as she was the one doing the 10 second timing. When Kelsey pulled the test tube out that held our pH, she inverted the tube twice before sticking it back into the spectrophotometer. We did this process for a total of 120 seconds and recorded the readings. Results: Table: Absorbency vs Time- Enzyme Activity Thursdays Lab Class Time (sec) pH pH pH pH (replicate) pH pH 0. 01 10 I . 420 0. 206 0. 694 -0. 070 0. 380 20 1. 750 0. 356 0. 820 -0. 033 0. 500 0. 644 30 2. 050 0. 430 0. 880 -0. 001 0. 538 0. 656 40 2. 340 0. 486 0. 940 0. 013 0. 586 0. 642 50 2. 660 0. 550 0. 960 0. 031 0. 614 0. 628 60 2. 940 0. 616 1. 000 0. 050 0. 648 0. 20 70 3. 150 0. 680 1 . 030 0. 074 0. 676 80 3. 400 0. 718 1. 070 0. 133 0. 700 0. 606 90 3. 700 1. 025 1. 110 0. 148 0. 728 0. 596 100 3. 900 1 . 090 1. 140 0. 151 0. 772 110 4. 100 1. 160 1. 180 0. 176 0. 792 0. 578 120 4. 200 1. 250 1. 210 0. 194 . 800 0. 570 color (after 120 seconds) deep rust deep rusty brown rusty brown orange rusty pink-brown The table above not only shows my groups pH level reco rdings, but also the rest of the groups recording as well. On the bottom of the table you will see the color of which those groups determined the contents in their test tubes to look like. While the amount of contents, absorbency readings and timing are all quantitative observations, the color inside the tube was a qualitative observation. All pH levels increased in absorbency except for phi. Because most of the pHs absorbency increased with time, that shows that the reaction teen the enzyme and the substrate are continuing and moving forward. Graph: Absorbency vs Time- Enzyme Activity- Thursdays Lab Class: In this graph above, you can visually see the dramatic increase in absorbency in pH while pH (replicate) has the lowest level of absorbency. Also take not though, while you cannot see it very well on this graph, phi has an absorbency that started out strong, but decreased as time went on. In order for us to determine the reaction rate, we needed to look at the information collected from the experiment that is listed on the first table of this report. I also created operate tables for each pH level for my own guidance. In the mathematical equation, you use y=mix+b. In this experiment, b is equal to O, so really you have y=mix. In order to find the slope or rather the reaction rate, we needed to do the rise/run=m which meant we needed to find the change in y and the change in x. The equation at this point would be ye-ye/xx-xx. Because yell and XSL are both O, you simply had to do ye/xx. In a simpler explanation, you take the 10 second absorbency and divide it by 10. That is how the rate of reaction numbers above came to be. This table includes all the pH data collected. For a view of what this looks like on a graph, please see below. Please take note that due to my excel, I was not able to make it a curve table as it should have been. Rather it is a table with strict points. You can see just the same the high points and low points that you would see if it was a bell curve table. Graph: Reaction Rate vs PH with all pH data: This graph shows that the absorbency level throughout the pHs goes down the higher the pH, meaning the lower the acidity. Though the information presented is all over the board which to me is telling me that most likely, there were errors n the experiment. I will discuss those further in the discussions and conclusions part of this report. There are a couple of outliers that I believe could be taken out in order for the data to be more correct. For those, I would choose to take out pH and pH (replicate). The reason for pH, even though it was the pH that my group was assigned to, it was significantly higher than the rest showing it to be one of the biggest outliers. I then am going to take out pH (replicate) because first, it is a negative number, and second, it is the second largest outlier. Updated Table: Reaction Rate vs H- Excluding pH pH (replicate)- Thursdays Lab Class pH Rate of Reaction 0. 0206 0. 0694 0. 038 PHI 0. 065 An updated graph for the table above is below: This shows a more linear graph with taking out those outliers. This changes the findings though as well from saying absorbency is decreased with a higher pH to the absorbency is increased with the higher PH. Discussion and Conclusion: The absorbency for all by phi increased as time passed; Though there wasnt a direct trend as to the higher the pH level the more it was absorbed or visa versus. In my hypothesis I stated that I believed that the rate of catechist oxides activity will change with the different pH levels. The findings supported my hypothesis because it showed that there was a significant change throughout the pH levels. The higher acidic pHs, such as pH and pH, ended up having the greatest absorbency, though pH was close behind. Phi actually had an absorbency that decreased as times passed. pH absorbency rate was significantly higher than the rest of the class which leads me to believe that we did something incorrect or that something went wrong in our results. While I thought we took special care when putting the contents into the tube and made ere that everything was working correctly, still many things could have gone wrong. We could have had air bubbles or a dirty cavetti that would not let the light to penetrate through, there could have been measuring errors, missed timings, cross contamination of solutions, or even the spectrophotometer could have been set incorrectly or it could have been drifting causing the incorrect information. So like I said, many things could have gone wrong. It seemed that a lot of the information from the other groups was also incorrect. It didnt show an optimum curve at all with the pHs which is the first indicator. So from there .NET ahead and took out the two largest outliers which was pH and pH (replicate) to try and get more of that curve and a more accurate finding. While it came closer to linear and more of a curve, I still believe that the findings in the class with the groups were mostly incorrect. So I would suggest that this experiment be repeated to get better and more accurate results. Because I excluded pH and pH (replicate) from my findings, I would have to say that pH was the most effective. It is more in the safe range for the pHs and is less acidic than pH and pH, which could mean that it allows for easier absorption.

Botox Essay Essay Example

Botox Essay Essay Example Botox Essay Essay Botox Essay Essay Bottom is used to get rid of wrinkles in aging adults. The main reason it was used was to help patients that had a stroke and their face muscles were drawn up. Bottom actually paralyzes the muscles instead of relaxing them. Men and woman are spending 600-1,000 bucks each time they go and have a treatment done which as to be done every couple of months. The ethical dilemma with this procedure Is people are using It to not show signs of aging when In real life people grow old and get wrinkles. They want to look young forever, and that is not the case in real life. Rich people are the only kind of people that can really afford it to be done because it cost so much to get the procedure done, but what if a person that cant afford it and really needs it done, but their insurance does not cover it? People believe that it is okay to have this procedure done to make them look younger, but others thinks its a waste of money everybody ages its a part of life that everybody will go through. People miss understand that in the beginning of the treatments it was meant for people with abnormal muscle tone and stroke patients but when the wealthy found out they used it to get rid of the wrinkles. My view is simply that I am against people who want to have Bottom not all people but the rich who believe that they need to get rid of wrinkles on their face. To me wrinkles are a part of life that Is the way god had Intended us to look when we aged. Problems associated with the issue would be Its costly, you have to have done way too often, and it was intended to help the sick people who actually really need. I believe when the rich found out they raised the price and became rich from it so when a person who really needs cant afford it they are Just left out. I would suggest that people who want it done to forget about because spending all that money that you could spend somewhere else is way more important getting rid of wrinkles for a couple months is just a waste when people who have problems really need to have it done. I would tell people not to have the procedure done because why you only have to please yourself and nobody else.

Company analysis-- Doctors without Borders Research Paper

Company analysis-- Doctors without Borders - Research Paper Example As such, this paper seeks to evaluate the factors that can impact on the operations Doctors without Borders, a non profit organization that offers humanitarian assistance to the people in need. The paper starts by outlining the background of the organization and it will also discuss issues related to management of diversity. The paper will also provide recommendations about the measures that can be taken in order to effectively manage the organization. Background information of the organization Doctors Without Borders / Medecins Sans Frontieres (MSF) is a non profit organization which works in nearly 70 countries providing medical aid to the people in need regardless of their race, religion, or political affiliation. This is â€Å"an international independent medical humanitarian organization that delivers emergency aid to people affected by armed conflict, epidemics, natural and man-made disasters, and exclusion from health care,† (MSF, 2013). The company is comprised of more than 22  000 workers including doctors, nurses, administrators and other professional staff among others. MSF reports that â€Å"in 2009, its medical teams carried out more than 7.5 million outpatient consultations; delivered 110,000 babies; treated 1.1 million people for malaria; treated 200,000 severely and moderately malnourished children; provided 165,000 people living with HIV/AIDS with antiretroviral therapy; vaccinated 7.9 million people against meningitis; and conducted 50,000 surgeries.† Managing diversity From the statistics presented above, it can be seen that Doctors Without Borders operates in various parts of the globe and it also works with people from diverse backgrounds. However, a critical analysis of this particular case shows that the major challenge for the organization may be related to managing diversity in order to effectively carry out its work so as to be in a position to achieve the desired goals. Given that the company operates in diverse enviro nments, there are likely challenges found in these environments such as dealing with people who have different cultural backgrounds and needs. The employees who work for this organization also come from diverse backgrounds and it may be quite challenging for the responsible authorities to effectively manage the affairs of the organization in each country. In his case, the manager ought to make explicit decisions which are easily understood by all the stakeholders involved given that they come from diverse backgrounds. Conclusion and recommendations A critical analysis of the given case study shows that the main challenge that can be encountered when managing organizational environments in different parts of the globe is related to managing diversity. It is not quite easy for an expatriate manager to manage people from diverse backgrounds by virtue of the fact that these people have different cultural backgrounds and values. It may also be quite challenging to manage the logistical o perations of an organization that operates across borders. Therefore, it is recommended that the responsible authorities at the above mentioned organization should implement the following measures in order for them to effectively manage its operations. The responsible authorities should make sure that they appoint a person with knowledge about the local environment to manage the organization’

How Convincing Is Porters Model of National Competitive Advantage in Essay - 6

How Convincing Is Porters Model of National Competitive Advantage in Explaining the Characteristics and Performance of the Business Systems of Major Economies - Essay Example This essay uses examples from Apple, CyberPower UK, Sennheiser, Sony and Lenovo to reach the conclusion that the framework is not a good assessor of business characteristics or performance in major economies, in an era of rapid globalization. Porter’s work focuses on home economies, leveraging home diamonds to create competitive advantages; he advocates entrepreneurship and innovation as drivers of advantage, rather than inherited endowments such as land, raw materials, and size of the labour pool, the lack of which he believes can be overcome. He further argues that factor creation is supported by the quality of consumer demand, rather than its size; the extent of relevant clustering and knowledge-sharing; and competition in the economy. Researchers have found cross-country evidence for all of these concepts. However, Porter’s concept of national competitiveness has also been criticized. Krugman argues that nations do not compete, like companies; and the idea of nation al competitiveness can be used to drive inefficient policies into play. Other researchers have criticized Porter’s methodology, arguing that global export shares are not a well-rounded measure of international competitiveness. Gray and Oz critique Porter’s narrow focus, which ignores macroeconomic environments and government policies, while Lazonic advocates that rivalry can lead to price-wars, decreasing the drive to innovate. In addition to this, Rugman & D’Cruz have created a Double Diamond Model, designed to fill in the gaps present in Porter’s model, which does not factor in the role of the multi-national enterprise. Perhaps the most case-based evidence in support of Porter’s Diamond framework emerges from his proposition on factor creation.
