Homeostatic Mechanism Essay Example for Free

Homeostatic Mechanism Essay Homeostatic mechanisms are essential for a body to maintain a stable condition. The word homeostasis describes the body’s ability to maintain its healthy state, while the world around it is changing constantly. There are many steps in the process of homeostasis. First, there is the stimulus that causes the change. Then the receptor detects the change. The information of the imbalance is then sent to the control center, which decides the response. The information entering into the control center is called the afferent pathway. During the efferent pathway, the information is sent out from the control center to the effector. The effector provides the means for the control center’s response, returning the body back to normal. An example of a homeostatic mechanism working is someone exercising, or running. This is known as the stimulus in the homeostatic mechanism. Consequently, the person is now breathing faster, their body temperature is rising, and their heart rate is increasing. By breathing faster, more carbon dioxide is entering into the body. This causes the pH level of the blood to decrease, making it more acidic. HHHhhhhdkjfkldsdjf The receptor detects this change and sends the information out to the control center. The control center then tells the cells to get rid of the carbonic acid in the blood. This causes the person to breathe even faster, prompting more oxygen into the body, getting rid of the carbonic acid. When the person stops running, the heart rate starts to return to the resting heart rate. The pH level of the blood also increases back to normal, which is about 7.35 pH. A homeostatic mechanism is basically a test of a person’s responsiveness. Without any homeostatic mechanism, the body would fill up with carbon dioxide and could pass out and die. A homeostatic mechanism in a body is necessary to maintain a stable condition.

Family Formations Essay -- Sociology Family Structure

Outline and critically assess the most significant crises, conflicts and changes in family formations over the last two decades (since 1990). Make reference to your own experience, in terms of changes in identity and identifications over time. In order to address the question it is important to present the evidence which shows that there have been conflicts, crises, and changes in society since 1990. It is widely understood there are many formations of the family. This involves the forever changing affects on society which bring us back to the family. This essay will discuss the social changes occur within the family paying particular attention to lone parenthood. It will look at changes to marriage, divorce, births outside marriage and poverty and look at to what extent these changes have had on British society since 1990, and also what these changes have meant to the family within. In Western Society, over the past two decades there has been significant changes in the which the family is forming. We have seen major shifts in the demographic constitution of the family and public policy, especially in terms of their formation and dissolution. As a result of this there is far more diversity in people's domestic and living arrangements compared to how they were earlier in the centuries. It has been noticed over these recent decades that living patterns between individuals are less and less conforming appropriately to the model of the nuclear family leaving some commentators to claim the family is in terminal decline. Increases in divorce, cohabitation, births outside marriage and lone parent families all result in old certainties to family formations being questioned.

Environmental Issues: Deforestation Book Project

Hannah Pilon Due Date: Friday February 8, 2013 Winter Term Library Assignment: Deforestation Marcus, B. A. (2009). Tropical forests. (pp. 125-135). Sudbury, MA: Jones and Bartlett Publishers. This chapter was very informative and gave a lot of information about the reasons of deforestation. I knew that logging and agriculture were major causes of deforestation, but this chapter taught me that mining too is also a big factor. The author was very knowledgeable about this subject and wrote in a way that was very easy to understand.This chapter also gave a very thorough explanation of the impacts of deforestation on the lands. Through this chapter, the author explains how just because a few trees are cut down, the water supply diminishes and can lead to drought as well as many other issues that I did not know about. This is probably my favourite source about this deforestation problem as it was easy to understand and the author did not drag out his writing and got to the point very quick ly. It was a good read! Forsyth, T. , & Walker, A. (2008). Forest guardians, forest destroyers. (pp. 20-21).Seattle, Washington: University of Washington Press. This is a short section within a larger book, but just because it may be small does not mean that it is not informative. In this section, it was suggested that deforestation occurring in Ghana is leading to the expansions of savannahs. I believe that this is an important section, as many do not realize that many African countries are also suffering from deforestation, which is depleting the lands, creating more savannahs and deserts. This section gave me further knowledge on the crisis of deforestation in Ghana and how it affects the people that live there.It explains how the soil is becoming depleted, which in the long term, will greatly effect the people living in these areas. De'Ath, C. , ; Michalenko, G. (1993). High technology and original peoples: The case of deforestation in Papua New Guinea and Canada. In S. Rietberg en (Ed. ), The Eathscan reader in Tropical forestry (pp. 281-287). London: Earthscan Publications Limited. This chapter is extremely informative. Within pages 281-87, it explains how a Japanese paper company has gone into Papua New Guinea and basically destroyed the land.I found this section to be informative and eye opening because the Japanese company only cares about money, they are exploiting the land which leaves the workers and the native peoples that live in these areas to be left with basically nothing. It’s amazing how much a culture can depend on a forest and when it is gone how much their life has to change in order to survive. I have also come to notice that companies are causing a lot of deforestation from other countries, which seemingly do not care about the locals at all.They only care about making money and forget about the human life that depends on the forest to survive. Avissar, R. , Ramos da Silva, R. , ; Werth, D. (2006). Impacts of tropical deforestatio n on regional and global hydroclimatology In W. F. Laurance ; C. A. Peres (Eds. ), Emerging Threats to Tropical Rainforests (pp. 73-75). Chicago, USA: The University of Chicago Press. This section within the chapter went into detail about the global impacts of deforestation. It explained that how deforestation in the Amazon Rainforest effected the rainfall and precipitation in the United States.I found this to be extremely interesting how if one part of the world is ‘damaged’ it can, and will, affect another part of the world, which will greatly affect the other country. I learned a lot from this little section and the authors did a good job and explaining how this process works. I really enjoyed reading this section and I had no idea that deforestation in one area could affect another country so drastically. It is amazing how our world and ecosystems are all intertwined and how delicate each one is. Grieser Johns, A. (1997). Timber production and biodiversity conservat ion in tropical rain forests. pp. 185-187). Cambridge, UK: The Press Sydicate of the University of Cambridge. Throughout these pages, the issue of animal extinction became a new issue that I knew was a result of deforestation, but for some reason had never occurred to me. This author explains that although at this moment a lot of rainforest animals are â€Å"vulnerable† if change does not happen, many of these animals will become endangered, if not extinct. With a lot of species not discovered yet, there is no true knowledge of how many animals in these rainforests are already endangered and on their way to being an instinct species.The pages that I have used in this book were very informational and very eye opening. With so many innocent animals are being put in danger everyday because of deforestation and its not just them anymore as plants are also in danger of becoming vulnerable and extinct. Mateiyenu Nanang, D. (2012). Plantations forestry in Ghana theory and applicatio ns. New York: Nova Science Publishers. The author is very knowledgeable and this shows through in his writing. Although he puts a lot of graphs and charts, sometimes it was confusing trying to understand the point he was trying to get across.From what I did understand, he was talking about how the logging in Ghana has become a larger industry in the past few years than ever before. Because of this, Ghana is starting to already starting to see the effects of deforestation. The author also went into detail about how they need to start replanting a lot more that they currently are because very soon they will be on the way to clearing out all of the trees that they have access too. Although this book was hard to understand at times, it was a very good resource and gave a lot of good information about deforestation in Ghana.

Affirmitive Action essays

Affirmitive Action essays Affirmative Action began in an era when minorities were highly under represented in universities and employment. Unless one was racist, most agree with the need of affirmative action in college admissions and in the workplace. With so much of Americas work force made from inter-raced schools now, some may question whether racism really is the problem anymore, and many college students might answer yes. We see it on college campuses today, and we are not sure why this is. Prejudices, self-segregation, political correctness, reverse discrimination, and ignorance all are put into a group of opinions surrounding affirmative action and racial issues today. One may feel that affirmative action in universities is the answer to the end of racism and inequality. If more black students get into good colleges, more of them will go on to even out the uneven numbers in the work force. Barbara Ehrenreich believes when we see ninety percent of leadership roles in the business world held by white men, we begin to doubt others exist in that field. With so many minorities in low roles, people begin to believe the white man is best for the top jobs (Ehrenriech 114). But with positive affirmative action laws at work, people should begin to recognize that minorities are just as good or better in the typical white mans job. Ehrenreich also believes affirmative action should guarantee that the best person no matter the race gets the job or gets into the school until it is all evened out (Ehrenriech 114). When blacks read false statistics about their failing race in articles sometimes it builds anger toward whites. The media shows that they are still not going to overcome the white man at the rate they are going. Affirmative action might not create racial unity even if we do reach an equal world we dream of though. The evidence is on the college campuses today. Though numbers are not near equal, minorities are a big part of university...

What I Learned Traveling in Israel without a Tour Bus

What I Learned Traveling in Israel without a Tour Bus On May 1st, I did something I haven’t done in over 10 years: I got on a plane and flew to a foreign country. I had been to Israel before, but only on pre-programmed tours. Here are some snippets of what I learned as a solo traveler traveling in Israel, visiting friends and giving a presentation as an international speaker at Google Campus Tel Aviv: Day 1: Arrival When traveling in Israel, it pays to have an official European style adapter for a MacBook Pro charger. The only way I could get my charger to work was to find a diagonal plug or a power strip on the ground. Anything else would not hold the bulky charger. Day 2: Hod Hasharon Get oriented. And don’t wander out on a 103-degree day without a hat and sunglasses, without knowing in which direction to take the bus. Don’t be shy about calling your friend for help. She will be willing to take you to the bus stop and save you from sunstroke. The buses don’t come on time. Don’t expect them to. Sometimes you’ll just need to take a taxi. The taxis don’t take credit cards, but they’ll accept U.S. dollars. When attending a yoga class in Hebrew, it’s a good idea to tell the yoga instructor that you don’t speak Hebrew. She’ll be much more likely to throw in English as necessary. Sh’efa, ven’shifah = Breathe in, Breathe out Thought you could get mixed greens in Israel that don’t include arugula? Think again. The buses don’t come on time in the afternoon either. Day 3: Swimming, Shopping and Shabbat If you’re nice to the lifeguard at the outdoor pool at the moshav, he’ll let you in for free, even if you’re not a member. The Central Bus Station in Jerusalem is like a small city. Be sure to have a shekel on hand to use the restroom! â€Å"King (Melech) Halvah† has the best halvah in Israel. And they give tastes! The dates in Israel are 10x better than anything you’ll get in the States. Don’t keep walking in sandals after they have worn a cut on your foot. The bike path in Jerusalem is beautiful, bordered by lavender and rosemary, and a lovely place to walk on Friday night. Do not expect to eat Shabbat dinner before 9pm, and do not expect it to be over until midnight. Expect deep conversation. Light your own set of candles if you’re in Israel for Shabbat, even if at first you think it’s okay to bless candles lit by someone else. Day 4: Shabbat in the Old City and Ein Karem Sleeping late on Saturday is the way to go after a late Shabbat dinner. Those yoga videos you purchased on special and downloaded onto your computer? They are great for a country that shuts down on Saturdays! There are stores and restaurants open on Saturdays in Jerusalem!   Ã‚  Ã‚  Ã‚   The stones on the walkways in the Old City are treacherously slippery. If your shoes slip, wear bare feet. You might offend some people, but at least you will not wipe out. When you see a door you are compelled to open, open it and wander in. You might be surprised at what you find. And your friend who didn’t want to see the art exhibit might just end up having multiple people she knows in common with the artist.   Ã‚  Ã‚  Ã‚  Ã‚   If you ask someone if you can pick fruit from their loquat tree, they will probably say yes. Loquats are delicious and pair well with those amazing dates. Always have cash on hand when traveling in Israel. Machines that are supposed to accept credit cards, well, sometimes don’t. Day 4: Dancing and Yad Vashem When assisting at a movement class for the elderly in Jerusalem, wear a high-cut top or some of the ladies might get offended. The men have no problem with it. Plan to spend a whole day at Yad Vashem (the Holocaust Museum) when traveling in Israel. The hours of testimonials are riveting. Four hours just isn’t enough. Don’t put money on your â€Å"Rav Kav† (transportation card) on the Jerusalem light rail if you want to use the money for a bus in Tel Aviv. Day 5: Joy Gym This is the land of the Bible. Where there is lightning, there could be hail. Be on the lookout for shelter. You can run into some interesting characters at Joy Gym in Hod Hasharon, including Eli Danker, an Israeli actor who teaches acting to Martha Graham dancers in New York, and usually plays a terrorist. You can look him up on IMDb. â€Å"Itzuvlates† with Rotem at Joy Gym is one of the best and most challenging fitness classes you’ll ever find! â€Å"Itzuv† means sculpting – so Itzuvlates is a combo sculpting and Pilates. The instructor is really encouraging too! There really is no way to get those light rail tickets converted to normal money on the Rav Kav. Try as you might. The 8-hour time difference between the US and Israel is great for freedom in the mornings; not so great for having any freedom in the evenings or for going to bed at a decent hour! If you take the bus to an address but it’s in the wrong city, you will be very late getting to your cousins’ house and probably not get to play with the baby. A 10-minute car ride can take an hour on 3 buses. Oy. Day 6: Artists and Eateries If you’re in Tel Aviv on a Tuesday, be sure to go to the Artist’s Market. You’ll find some beautiful objects there! I bought a Shabbat set that holds tealights instead of the tall white candles I grew up with, and a turquoise scarf with butterflies! Then wander over to Ouzeria, a restaurant with a Greek twist, patronized by locals – best food I had while I was in Israel! Office buildings in Tel Aviv can look like this: Bargaining is all about the facial expression. Biggest win: A chunk of halvah knocked down from 45nis (shekels) to 30nis. Score! Day 7: Google Campus Tel Aviv Office buildings in Israel can also look like this:   Ã‚   Israelis can be an enthusiastic and challenging crowd! Networking meetings can be set up on a dime. I met the next day with a recruiter who attended my presentation! The Mexican chocolate popsicles at the Sarona Mall are worth the trip. Day 8: Final Day It doesn’t take long to make friends at the gym. Eli Danker was there again! It’s possible to live in Israel without speaking a word of Hebrew. I met another client who lives there and works for the U.S. federal government and she knows one phrase: â€Å"Tax receipt†! Landver might be a chain, but they have really great food, from salads to smoothies to pasta. Yoga classes at Joy Gym are not for advanced students. Stick to EllaYoga! A gathering of 6-8 people can be created on a dime. People show up! Lovely evening at the outdoor seating at Landver. Day 9: Farewell Israel! Taxis come 15 minutes early in Hod Hasharon. Better than 15 minutes late! Your friends in Israel will want you to move there. Refrigerator magnets at the airport are a great way to spend those last shekels. Leaving Israel feels sad. Already looking forward to the next trip. L’hitraot (until we see each other again)!

TARGET CORPORATION FINANCIAL ANALYSIS AND INTERPRETATION Essay - 2

TARGET CORPORATION FINANCIAL ANALYSIS AND INTERPRETATION - Essay Example This refers to how fruitful a company is in using assets. Liquidity and efficiency are significant and complement each other. To calculate a company’s short term liquidity (requirement) we need to figure out the current ratio and working capital. Working capital is the current assets less the current liabilities. To calculate the current ratio we divide the current assets by current liabilities. In looking at the objective organization’s financials for years 2004, 2005 and 2006 we can see how sound they performed over the years. 4,638 was its working capital in 2004. We got this by subtraction of current liabilities of 8,134 from current assets of 12,952. 5702 and 4817 was the working capital in 2005 and 2006 respectively. Now we have to look for the current ratio for these same periods. In 2004 current ratio for Target Company is 1.56. We got this number by dividing 12,952, which are current assets, by its current liabilities, 8,314. In 2005 and 2006 the current ratio is 1.69 and 1.50 respectively. It reflects the company’s ability how use assets to create sales. It is an important aspect in a company’s working efficiency. To calculate this we divide net sales by average total assets. Target Company the asset turnover for 2004 is 0.20. It can be determined by its net sales of 3,198 and divided by average of total assets of 15,708. The asset turnover rate was 0.15 for 2005. In years 2004, 2005 and 2006 we can see that from 2004 and 2005 there was an increase in liquidity and efficiency but in 2006 there was a fall. Although there was a fall, Targets results are not that unusual from other companies, in fact some had even bigger decreases and struggled more within the same time period. I would like to invest in the Target Corporation; with the drop from 2005 to 2006 at the overall picture the drop is not that
