Whole Food free essay sample

Whole Foods Market had evolved into the â€Å"world’s largest retail chain of natural and organic foods supermarkets. † Their rapid growth and success is primarily due to being highly selective about what they sell, as well as being dedicated quality standards and core values. Whole Food’s stated mission statement was to â€Å"promote vitality and well-being for all individuals by offering the highest quality, least processed, most flavorful natural and naturally preserved foods available. † The key opportunities for Whole Foods include: increasing attractiveness of the health and organic food industry, growth through acquisition, and enhancing their brand image and loyalty through community service. Whole Foods has already bought its largest competitor, Wild Oats, which has shown to be profitable. By promoting organic foods Whole Foods can increase sales and attract new customers by introducing them to the Whole Foods experience. Whole Foods would benefit not only by promoting itself but the industry in general. We will write a custom essay sample on Whole Food or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In addition to promoting organic foods, they could enhance their brand image and loyalty by continuing their community service efforts. If the industry continues to grow and they continue to bring about brand awareness and loyalty, Whole Foods could strengthen its market share and profitability. ? The key threats that Whole Foods faces include: local grocers increasing their organic food options, the size of Whole Foods stores deterring customers, and the price of organic foods. Local grocers could potentially take away from Whole Foods sales by stealing the customers that want to get in and get out. If customers can get the organic foods they want at a smaller grocery store, some customers may switch to them. This is where the size of Whole Foods’ stores becomes a threat to themselves. If they continue to buy and build large stores they could potentially deter some of their consumers to the smaller grocers in the area. Also what is a threat now is the high price of organic foods. Consumers must pay a premium for these items because they cost more to produce. Whole Foods must keep the customers they have now loyal or they could lose them to non-organic foods that are cheaper. The organic foods market is very attractive and continuing to increase in attractiveness. Whole Foods holds a very strong position in the market and could potentially position themselves in an even stronger and more profitable position. Health and organic foods have become very popular and show no signs of slowing in demand. The processes by which organic foods are made will only become less expensive as new technologies and continuing knowledge of the industry grow.

Dell Computers essays

Dell Computers essays Dell computers is still the leading computer provider in the world, it has been able to maintain its position since the 1980s as a result of its highly efficient computer building and manufacturing process, combined with excellent customer service. Dell has been able to systematically beat out competitors by providing an extremely streamlined supply chain process that far outstrips their competitors. Since the late 1990s, it has been able to process the majority of their sales through online portals, eliminating the need for massive store fronts. This strategy has worked well for them as they have expanded their overall user base and have been able to decrease their overall costs associated with output. Dell has been performing at a very high clip in the past year. Its overall earnings in the past year jumped by more than 25%. Its overall earnings have actually outpaced its rise in sales, which was 19% in the last year. They have emphasized products that are high margins by streamlining their overall delivery process and human resources costs. Its current strategy of pursuing high-margin products within key new geographic demographics is working well. In addition, Dell has been able to expand its international division and sales substantially are pushing products into specific markets outside of the United States. Despite these evident gains however, Dells overall stock price has dropped substantially over the past year. Since the end of 2006, stock prices have dropped as much as 16%. This decline in stock price is worrying for investors as they continue to look at the performance track record for Dell computers. The problem is that Dell has had a poor track record for meeting investor projections and analyst expectations. Unlike their direct competitor, Hewlett Packard, which has seen its stock price rise by as much as 27% since the beginning of this year, Dell consistently fail to meet growth metrics specif...

Medicare Research Paper Example | Topics and Well Written Essays - 1250 words

Medicare - Research Paper Example It is a program being implemented by the Centers for Medicare & Medicaid Services. Medicare is divided into four parts. The first part is the Hospital insurance (Part A). This helps to pay for inpatient care in a hospital or skilled nursing facility, (after hospital stay), home health care and hospice care (Social Security Online, 2010). Medicare insurance (Part B) covers doctors’ services and other medical services and supplies which are not covered by hospital insurance (Social Security Online, 2010). Medicare Advantage (Part C) can be availed of in many areas. Those under Medicare Parts A and B can opt to receive all their health care services through the provider organizations under Part C (Social Security Online, 2010). Finally, drug coverage (Part D) assists in the payment of medications for which doctors prescribe for the treatment of their ailments (Social Security Online, 2010). Medicare is different from Medicaid. Medicaid is a program which provides aid for those who cannot afford medical services. Different states have different rules on eligibility and coverage; and in some cases, these programs do overlap and some individuals may qualify for coverage under both programs (Social Security Online, 2010). This Medicare program is significant for public health because it helps ensure that all people receive quality health care and are entitled to improved outcomes (DeWalt, Oberlander, Carey, and Roper, 2006). Some studies also point out that Medicare programs help control the cost of health care as it improves health outcomes of the people covered. It also helps prevent illnesses and reduce waiting times with doctors; and through the coordinated efforts of the Medicare programs, many states are able to encourage practices which â€Å"improve the timelessness of care and also†¦reduce the rate of no-shows to clinic appointments† (DeWalt, Oberlander, Carey, and

Short and Long Term Affects on Fetal and Child Development When Essay

Short and Long Term Affects on Fetal and Child Development When Exposed to Cocaine in Utero - Essay Example Short and Long Term Affects on Fetal and Child Development When Exposed to Cocaine in Utero Another aspect of self regulation is heart rate: â€Å"Specifically, HR is predictive of later cognitive development and may impact reactivity to external stressors. An elevated resting HR is indicative of a higher level of physiological arousal which impacts both the quality and quantity of infant responsiveness to stimulation† (Schuetze 2006). Clearly, an elevated infant heart rate can be indicative of over-stimulation and a precursor to later cognitive developmental delays. Other aspects of self regulation or homeostasis that are thought to be affected by cocaine use in utero are respiration, blood pressure, sleep patterns, and body temperature. Studies have also indicated that cocaine use by pregnant women reduces blood flow to the placenta and causes fetal vasoconstriction. The placenta is the virtual nutrient source for the fetus. Adequate blood flow to the placenta and overall placental health are critical to fetal health. Cocaine is responsible for inducing the release of certain body chemicals called serotonin and/or epinephrine. The release of these two chemicals has a direct affect on vascular tone and therefore affects the vascular health of the fetus as well as the placental blood flow. Fetuses which develop in utero with a less than healthy placenta experience both short and long term developmental effects as well as defects.

Lossless predictive coding

Lossless predictive coding Objective of the project Generating Huffman codeword using Huffman Coding to be transmitted to the decoder. Compare and analyze quality of 7 linear, fixed different Differential pulse code modulation (DPCM) predictors to find out which one achieves the best compression ratio. Compare and derive the compressed image against the original image to ensure our result has lossless compression. Introduction As we know, there is strong correlation or connection between spatially adjacent pixels. The aim of the predictive coding is to remove redundancy between consecutive pixels to facilitate the encoding of only the residual portion between actual and predicated (only new information). In other way, a pixel is coded as the difference between its actual value and a predicted value, which was computed from previously decoded values. As a result of that, compression ratio depends on the variance of the image, level of quantization of the difference values and quality of the prediction. After predictive coding, we can start to compress the original file size by using Differential pulse code modulation (DPCM) encoding and make a Huffman entropy codebook before transmitting the image. The decoder uses the Huffman codebook to first decode the Huffman entropy and followed by decoding Differential pulse code modulation (DPCM) to derive the constructed image.. Experimental result Differential Pulse Code Modulation (DPCM) Encoding Encode original Lena512.pgm image to DPCM values using 7 linear and fixed different Predictor methods: A (A + C)/2 (A + B + C)/3 A+B-C A+(B-C)/2 B+(A-C)/2 (A+B)/2 According to 7 above formulas, we can compute the difference between the previous pixel and current one. The predictor code table result will be sent to the next step, entropy encoder. The results show that the DPCM predictor B + (A -C)/2 achieves the best compression Ratio Entropy encoder (Huffman coding): Below part shows how the approach of Huffman coding is generated: Step 1: Retrieve the output of DPCM encoding. Step 2: Each value from DPCM encoding will be generated according to each occurrence probability in descending order. Step 3: Assign the Huffman codeword for each computed probability value For example: Each child probabilities is added to create the parent. The adding of probabilities continues until the root with final probability 1.0 as shown above. Hence, the Huffman Coding Table is formed. A bit is assigned to every node. The 0 bit is assigned to every left sub-tree of every node and the 1 bit is assigned to every right sub-tree of every node. Average length per symbol = 10.6+20.2+30.1+30.1= 1.6 bits/symbol In our experiment, since the optimal predictor is B + (A -C)/2, the codebook is generated according to this predictor. The DPCM values ranges from [-75, 87]. The table below shows the first 8 values among 162 DPCM values in Huffman codebook. RESULT DISCUSSIONS: (Optimal Predictor B + (A -C)/2, Encoding Part) Average bit/pixel=Compressed Size (Bits) / (columns x rows) =Compressed Size/ (512 x 512) After generating 162 codewords we are able to achieve 902428 bits. The derived average bit/pixel is approximately 3.442 bits/pixel. Compression Ratio= Original image size / Compressed image size Compression Ratio= 8 bits / (Average bit/pixel) (image resolution: 8 bits per pixel) The original image (Lena512.pgm picture) is a fixed 8 bits/pixel. Therefore, the compression ratio is 8/3.442=2.3239 by using Huffman codes. In order to write a file into binary bit format, the 8 binary adjacent bits is read and converted an integer. For Huffman decoding, the integers are written into a file. Entropy decoder (Huffman Decoding): The Huffman decoder uses the compressed image to regenerate the DPCM table. The compressed file integers are read and converted into a set of binary bits. If the binary code is not a prefix of any code, read each and every bit in the codebook to find a match. If no match is found, continue the search till a match is found in the codebook. Retreive the corresponding DPCM value for the binary code set. Step 2 is repeated until the binary set is exhausted. A DPCM table is generated and this is called the DPCM decoding process. For example: After converting integers into a set of binary bits, we have encoded bit stream of the first few pixels: 110111001101110011011101 According to Huffman lookup table, the corresponding DPCM values are: 87 87 86 DPCM Decoding: After decoding DPCM, the reconstructed image is retrieved. According to the above images, it can be concluded that the compression is a lossless one. There is no difference between original image and compressed one, as above images shown in reality or DPCM values encoded and decoded in theory. Project Discussion Analyzing Different Predictors for Lena.pgm Through above diagram, we can see the compression ratio of using one neighboring pixel (Predictor 1: A) for prediction is lower than using two or three neighboring pixels. And predictors which use 2 neighboring pixels have lower compression ratio than ones with 3 neighboring pixels Analyzing Different Predictors for other images: To further evaluate performance of the predictors, 4 different images were chosen to compute the effects the performance of the predictors. From the above diagrams, compression ratio of methods from 3 to 6 (They are: (A + B + C)/3, A+B-C, A+ (B-C)/2, B+ (A-C)/2 ) is higher than the rest. As there is strong connection between adjacent pixels, any predictor which can utilize connection between adjacent pixels produces good compression ratio As a result of that, the methods which use 1 or 2 neighboring pixels can not utilize this connection well. For example: Predictor A is used (only 1 pixel is used) for the first method. The encoded values are dependent on the previous value of the same row. Thus, the first columns values cannot be predicted or this predictor does not use connection between neighboring pixels appropriately. On the other hand, the images that fall at the center region have a lower compression ratio than ones which spreads over the entire white-grey-black scale.. Since the conducted experiments pertain only on .pgm format images (Black-And-White image), it is unable to determine compression ratio of colored images (RGB, YCbCr, HSV color bases) Conclusion According to all above experiments and diagrams, we can assert that there is no one definite predictor for every image to achieve best compression ratio because different images need different predictors to achieve better compression results. In general, since there is strong correlation between spatially adjacent pixels, any predictor which can utilize connection between adjacent pixels produces good compression ratio. In our experiment compression method from 3 to 6 will produce better compression than the rest. In reality, Static Huffman Coding is popular and easy to implement but does not obtain theoretically optimum number of bits to encode symbols because of condition: Huffman codeword must be an integer number of bits long, e.g. if probability of 1 symbol is 0.9, the optimum code word size should be 0.15 bits but in Huffman Coding, it is 1 bit. Moreover, if symbol probabilities are unknown or not stable (source changes), Dynamic Huffman coding should be chosen but the implementation is very complicated. On the other hand, so as to achieve non-integer length coding and probability derived in real-time, Arithmetic coding is a good alternative. However, the implementation of Arithmetic coding is slow due to many multiplications (in some cases, divisions).

How Charlotte Bronte Uses the Different Houses in Jane Eyre Essay

How Charlotte Bronte Uses the Different Houses in Jane Eyre In the novel Jane Eyre, Charlotte Bronte uses different locations in particular different houses to produce a structural base for the story and to provide a basis for Jane’s progression through life and the changes she experiences. The houses are a background to the plot of Jane Eyre that is the evolution of Jane from lonely orphan at Gateshead into an established and well-developed character at Ferndean who is Mr Rochester’s equal. Throughout the story Jane lives in many houses all that are different in certain aspects but in some aspects they are similar. One such aspect is that all the houses have a dominant male in Gateshead it is John Read in Lowood it is Mr Brocklehurst and at Thornfield even though she is equal to Mr Rochester when they are alone when guests are present she must then observe the social hierarchy which means Mr Rochester is dominant over Jane. Another similarity is that in each of different and contrasting houses there is always an over all feeling of Jane being trapped and constrained inside their walls. Jane is always fighting against the dominant males in the houses as seen when she encounters John Reed and calls him a murderer. She always rebels against the dominant male in the household until she meets Rochester who is not only the dominant male but also a kind and loving person. Apart from the dominant male in each house there is also a kind guide such as Bessie in Gateshead and Miss Temple in Lowood. There is one exception and this is in Thornfield where Mr Rochester is both the dominant male and kind presence in the house. In Jane Eyre houses play an important part in shaping and forming the structure of the nov... ...gainst the mystery of Grace Poole and her connection to Mr Rochester. Unlike her stay at Gateshead she is allowed both a social position as a governess and respect member of the house her personal situation with Mr Rochester. Since Jane is a governess and is not of the higher class that Mr Rochester is from. She cannot appear to be involved with him but this only when outsiders arrive. This also represents that Jane is not rebelling against the hypocrisy with Mr Rochester because if she were then she would not observe the social hierarchy. Like all the places Jane has lived in so far Thornfield does supply the amount of freedom that Jane would like. She is still trapped in to certain degree and she longs for something more. She wants just a bit more freedom but she cannot get that at Thornfield at the time she is there. The only place in Thornfield

Toothpaste Out of Baking Soda

Chapter I The Problem and its Background Introduction Many people nowadays are urged to be aggressive, to get ahead of the rest and to be number one. We are pulled by media toward self-centered pleasures. So many commercials show us a lifestyle of pleasure and according to them can makes us happy. We are most of the time driven by their promises of making us comfortable and beautiful. The products they are advertising may have bad effects on our health that they may not spill out to us for the reason that their products may not be sold. These products may contain harmful ingredients and chemicals that may lead to diseases and abnormalities in our bodies. An example is the commercial toothpaste. Commercial toothpastes are full of chemicals and some of the ones that you see on your shelves have been shown to contain harmful ingredients. Research has proven that sodium lauryl sulfate or (SLS) found in most toothpastes have a tendency to dry out the lining of your mouth and gums. This can cause gum damage and sores in the mouth because of the acidity in foods and drinks that the lining would normally protect against. Statement of the Problem The study aims to discover the advantages of making your own lemon-flavored toothpaste out of baking soda instead of buying from the market. The study seeks to answer the following questions: 1. What are the advantages that we can get from making toothpaste out of baking soda? 2. What are the effects of making your own toothpaste to those who will be using it? 3. What ingredients or materials help whiten and polish teeth? 4. What are the other possible flavors that can be added to the toothpaste aside from lemon zest? Scope and Limitation The study focuses on the advantages of making your own toothpaste out of baking soda. It is confined on what are the benefits the user can get from making their own toothpaste and how it will affect their teeth health. It does not include the research on the other ways of making your own toothpaste aside from baking soda. Significance of the Study This study will benefit the following: The ordinary people. For them to be informed of the effects of using comm ercial toothpastes. The parents. For them to save money in times they become short and to be sure of the ingredients that go in to their toothpaste. The teenagers. For them to develop their creativity in making their own toothpaste and for them to know what materials actually help the teeth become healthy. Definition of Terms Toothpaste is a substance for cleaning the teeth in the form of paste. Baking soda or bicarbonate of soda, is a leavening agent used in baked goods like cookies or quick breads. Lemon zest are  tiny bits of lemon peel Glycerin is a clear, colorless, syrupy  liquid  that occurs extensively in nature and is naturally found in the  cells of  plants,  animals and humans. Hydrogen peroxide is a colorless, heavy, strongly oxidizing liquid, H2O2, capable of reacting explosively with combustibles and used principally in aqueous solution as a mild antiseptic, a bleaching agent, an oxidizing agent, and a laboratory reagent. Chapter IV Summary, Findings, Conclusions and Recommendation Summary The study aims to discover the advantages of making your own lemon-flavored toothpaste out of baking soda instead of buying from the market. Toothpaste  is a paste or  gel  dentifrice  used with a  toothbrush  as an accessory to clean and maintain the aesthetics and health of  teeth. Most of the commercial toothpastes that can be bought from the market contain harmful ingredients. This can be avoided by making your own toothpaste. To make your own lemon-flavored toothpaste, we will just mix everything up. To make the lemon zest, you will just grate the peel of a lemon by rubbing the lemon on the grater. In adding up the lemon zest, you can experiment on it. It’s the part where you can have fun. We observed that our final product, the lemon flavored toothpaste out of baking soda, became color yellow. After we have tried it, we felt freshness in our teeth. Also, based on our research, baking soda does really help whiten teeth and in fact, it is an element of most toothpaste and have been approved by the American Dental Association to be a component of most toothpaste. Findings The advantages that we can get from making toothpaste out of baking soda are that, you can know that you are using an all-natural product. These are a more natural alternative and they do a wonderful job at cleaning the m outh. Making your own toothpaste will help you save money and you will have the benefit of knowing the exact ingredients that go into your own toothpaste. Your toothpaste will not have any artificial ingredients that color it and flavor it. You will be able to avoid sweeteners, artificial ingredients and preservatives simply by making your own toothpaste. The people who would be using their homemade toothpaste will have a chance to show their creativity and personalize their toothpaste. They would be able to know the ingredients that are needed to help whiten teeth. Baking soda and hydrogen peroxide are the ingredients or materials which help whiten and polish teeth. Baking soda has a natural cleansing ability and can even be found in some commercial toothpaste. It's non-toxic and will help polish your teeth. Hydrogen peroxide naturally disinfects your mouth and will also help whiten your teeth. Aside from lemon-flavored toothpaste, you can also have any other fruit flavor you may like for your toothpaste. You can also have mint-flavored toothpaste by adding peppermint oil or cinnamon.
