Little miss sunshine Essay Example
Little miss sunshine Essay Interior of a asss family home. The dilapidated walls are a mustard color while the doors are starting to fall off their hinges. Olive stands in front of the full bodied mirror in the bathroom after the Little Miss Sunshine beauty pageant and look at herself in disgust. Shes wearing a light pink top and red leggings along with her red sweatband. The colors clash like two stubborn people. Theres only a small amount of light being let in by the window through the rip in the curtain and its shining right t Olive. Shes started reflecting on the Journey she has Just arrived back from and its then she realizes, shes not good enough for anything or anyone. Olive: I thought I was doing a good thing. I thought it was going to be all worthwhile. I thought I was going to win Why did you ever think you were going to win? I mean seriously Olive, look at yourself and then remember those other beauty pageant girls. You were nothing like them: their nice tans and their slim bodies, their nicely done-up hair and their makeup. You have none of that. You could never have won even if you tried. Youre a loser and thats all youll ever be (sighs). Olive keeps looking at herself in the mirror pulling at her hair and her clothes The sad thing about it is though that the one person you thought you could trust actually was the one that let you down in the end She looks up to the sky as she starts talking about granddad. She paces back in forth across the room. She is starting to harden her tone as she goes. Whod you do it grandpa?

You made the whole family look like fools, and you werent even here to support me in the end. No, you know what I realism now? Youre a selfish coward that never cared for any of us. You Just decided that your addiction (said sarcastically) was more important than me, the most beautiful girl on the planet. Your words exactly.. How could you? I relied on you, I needed you.. Olive subtly starts to soften her tone as she goes and sits on the side of the bath with her head in her hands. Right from the beginning, I always told myself that you were always the one that was going to be my side until the end. The one that was always going to look out for me, support me. Encourage me to be the best I could be in life, but now.. Now I feel as if you have Just used me for one of your little games and its not fair on me. I dont even feel as if I belong in this family already and youve made it worse for me. Olive stands and goes back pacing back and forth and starts talking to the rest of her family. Youre all ashamed of me and I can tell. I can tell by the way o all make subtle hints about my weight and the little looks you all give me. I know Im not the winner you wanted me to be dad but Im doing the best I can, I only entered that contest because I wanted you to be proud of me. I wanted everyone to be proud of me for once. Mum, I know you wanted to let me be who I wanted to be, but I wish you had of Just told me the truth rather than lie to me. Yes, you wanted to protect me But sometimes protecting your little girl meaner having to be truthful. I can handle it, Im older now. I dont need protecting. Olive goes back to standing staring t herself in the mirror and starts talking to herself again. I guess deep down I really did know what grandpa was trying to achieve and I turned a blind eye to it. I just wanted to make him proud, make the rest of you proud. Its your fault in the end olive, I mean look at yourself. Youre nothing like those beauty pageant girls with their have none of that. So stop trying. Olive goes and sits in the corner of the bathroom huddled in a ball and starts to cry.

How to Prepare a Winning Business Pitch
How to Prepare a Winning Business Pitch How to Prepare a Winning Business Pitch To get a business idea off the ground, you may need some investment. And this means youââ¬â¢ll need to convince investors that you have a great business plan. But what goes into a good business pitch? A few things to consider when pitching a business include: The type of business pitch youââ¬â¢re preparing (e.g., verbal or written) Details to include, such as your target customers, market research, etc. Who youââ¬â¢re pitching your idea to and what theyââ¬â¢re seeking. Who you are and who youââ¬â¢re working with in the business venture. How much to include in your pitch (as compared to a full business plan). So letââ¬â¢s take a closer look at how to prepare a winning business pitch. 1. Written vs. Verbal Pitches If youââ¬â¢ve been asked to pitch your business, make sure you know what type of pitch to give. The main distinction here is between written and verbal pitches: A written pitch is a short document, typically between one and three pages, where you outline the nature of your business for investors. A verbal pitch is a presentation you give to potential investors in person. This could be a short elevator pitch, which would last up to two minutes. Or it could be a full presentation with backup visuals and documentation. Chances are youââ¬â¢ll need to use both at different points of pitching a business (e.g., selling the idea with a short elevator pitch before writing a written pitch to flesh out the details). Thus, you should try to find out what kind of pitches investors are seeking and tailor yours accordingly. If you are preparing any written documents as part of your pitch, , moreover, make sure to have them proofread. This will ensure they are error free and easy to read, demonstrating your attention to detail. 2. The Essentials of a Business Pitch The exact content of your business pitch will depend on the kind of business youââ¬â¢re pitching and the type of pitch youââ¬â¢re delivering. However, there are at least a few details that any business pitch should include, such as: A brief overview of your business idea and your overall goals (this could be the introduction for a longer presentation or written document, but it might be the entirely of an elevator pitch). Your target customers and how your business idea will serve them. The market youââ¬â¢re entering and the opportunities it presents. How your business will distinguish itself from existing competitors. Your financial projections, including revenue and profit forecasts. Key team members and any partners you will work with in your business. How much investment youââ¬â¢re seeking and how you will spend it. Remember, though, that a business pitch is not a business plan. Itââ¬â¢s about selling an idea. As such, telling a compelling story can be more important than the pure details. For instance, when outlining your business, you could tell an anecdote that demonstrates the need for your product. This can help your pitch resonate on a personal level ââ¬â itââ¬â¢s about how your business will help real people, not just how much money you hope to make. 3. Do Your Research on Investors It always pays to do some basic research on investors before preparing a pitch. This will give you a better idea of what different people and groups are looking for in a business, as well as giving you a sense of the kind of pitch investors are expecting. Try to find out: Whether they typically invest in certain business types or areas, especially if this matches the profile of your proposed investment. If they usually invest in specific geographic regions. How much they usually invest and what they seek in return. Whether they take a hands-on or hands-off approach to companies they invest in and how this might affect your proposed business. This will help you pick the right investors for your business idea. 4. Sell Yourself Donââ¬â¢t forget youââ¬â¢re part of your business pitch! In fact, some investors focus more on the people pitching a business idea than what they are pitching. A great idea can be worthless in the wrong hands, after all, so you need to show investors they can trust you with their money. As such, you should include something about you and your teamââ¬â¢s past achievements in your pitch. If possible, focus on success stories that show you know how to start and run a business. 5. Donââ¬â¢t Overload on Information Finally, when youââ¬â¢ve prepared a first draft of your pitch, cut it down to the essentials. The most common error when pitching a business is trying to cram too much in, especially in a verbal pitch, where you may end up rushing. Remember: this is a pitch, not a plan. So rather than launching straight into a full five-year financial breakdown, focus on key details that make your idea appealing. Another tip is to use visual aids, such as charts and tables, which can stop your presentation becoming too wordy. Ideally, your visual aids will be more detailed than this. In other words, your priority in a pitch is to make investors interested in your idea. And you wonââ¬â¢t be able to do this if theyââ¬â¢re struggling to keep up with reams of information. Of course, if all goes well, the people youââ¬â¢ve pitched to may ask follow-up questions. Or they may ask for a full written plan. This is when youââ¬â¢ll need the in-depth research youââ¬â¢ve prepared. But try to keep things engaging until you know the investors are already hooked!

Changes in Earth's Albedo Measured by Satellite (Wielicki et al, 825) Essay
Changes in Earth's Albedo Measured by Satellite (Wielicki et al, 825) - Essay Example The global albedo is found to change with changes in the cloud cover, amount of atmospheric aerosols, and forest, snow, & ice cover on the earthââ¬â¢s surface. The magnitude of impact on global albedo due to events caused on earth can be demonstrated by the following example ââ¬â A volcanic eruption in Mount Pinatubo in June 1991 released aerosols in the stratosphere, which raised global albedo by almost 0.007 in a span of two years. A larger increase in global albedo with unknown causes was reported to occur between 2001 and 2003. In order to investigate whether any significant changes in global albedo occurred between 2001 and 2003, Wielicki et al. examined the observations made by global satellites that measured changes in the earthââ¬â¢s albedo (825). These observations included those made by CERES (Clouds and Earthââ¬â¢s Radiant Energy System) of NASAââ¬â¢s Terra spacecraft. The monthly anomalies in the data caused by seasonal changes were nullified and data was plotted. The data provided by CERES covers global observations for the complete solar spectrum ranging from a wavelength of 0.3 to 4 à µm. The observations of the global data reveals a small decrease of about 0.006 in the global albedo corresponding to about 2 W m-2 decrease in the shortwave reflected flux. These results contradict with those obtained by Palle et al, who demonstrated a large increase of about 0.017 in the global albedo corresponding to an increase of about 6 W m-2 in the shortwave reflected flux. Independent observations made by two individual CERES instruments were compared. It is believed that the 1.1 W m-2 decrease in the flux observed by one of the CERES instruments could be due to exposure to ultraviolet radiation during a hemispheric scan. When taken into consideration, this further reduces the anomaly to 0.9 W m-2. Wielicki et al. further explain the effect of change in albedo on earthââ¬â¢s climate (825). When changes in land surface, aerosols, and fores t, snow and ice cover is the cause for change in albedo, then increasing albedo results cooling of the earth and decreasing albedo results in warming. These changes on earthââ¬â¢s surface significantly influence the amount of reflected solar radiation but have comparatively minor effects on the emitted thermal infrared radiation that results in cooling. Wielicki et al. contend that if observations made by Palle et al. were correct, then there would have been global cooling double of what had been observed in the Pinatubo eruption. However, such a global cooling was not observed. Furthermore, Wielicki et al. explain another possibility that the earthââ¬â¢s total ocean heat storage could witness a significant reduction. It is estimated that between 2000 to 2002, the ocean heat storage has experienced an increase of 0.7 W m-2. In order to account for the global changes in reflected solar flux, the flux in ocean heat storage was scaled to global surface area from an ocean-only are a utilized by Willis et al (Wielicki et al. 825). According to Wielicki et al, if changes in global albedo were occurring, then there would be a decrease of 0.7 à ± 0.8 W m-2 in the reflected flux. This is found to be consistent with the observations made by CERES. Until now, only the effects of change in albedo have been discussed. Cloud changes may also be affecting both the earthââ¬â¢s albedo and its thermal infrared cooling, and may also be a cause for albedo changes that do not

Verification Of Faradays First Law Of Electrolysis
Verification Of Faradays First Law Of Electrolysis My research question How can Beers law be used to verify Faradays First law of electrolysis and to determine Avogadros number and Faradays constant by electrolysis of 1.000 mol dm-3 copper sulfate (CuSO4) solution using graphite electrodes? is an indirect question to the investigation. I was always interested in verifying laws and learning about interdependence between laws. I was so keen in finding how that how the nature of one law depends upon another law as chemistry a whole subject depends upon multiple concepts. So I took this opportunity to show how one law can be proved using another law. Here in my research I have shown how Beers law can be used to verify Faradays First law of electrolysis and I have also used Beers law to determine Avogadros number. This research clearly indicates that there is interdependency between laws. In the verification of Faradays First law of electrolysis of CuSO4, we generally focus on mass of Cu deposited, but not much on color. My focus was that how to use this phenomenon / property of change in intensity to calculate mass indirectly. The same concept of absorbance in Beers law applies while determining Avogadros number. I did the experiments to verify Faradays First law of electrolysis and to determine Avogadros number in indirect manner. Indirect methods have often helped scientists to get their results better and we also have good examples for Back titration and chromatography. So with the same expectation in mind, I came with such a topic for my research. Slight modification in the experiments can really help. I did use graphite electrodes because they are cheap, it is therefore widely used in electrolysis rather than platinum as it is costly. The disadvantage for graphite electrodes is, it flakes off and therefore mass readings of Cu deposited over graphite electrode are highly unreliable. So as the result is highly unreliable, we might not get the accurate readings of the mass of Cu deposited at cathode. But if we use the colorimeter technique to find out the deposition, the mass of graphite lose in the electrolysis process is not affected. I mainly focused upon the absorbance value by the diff erence of color. Once while performing an experiment on electrolysis during my school days, I was using graphite electrodes and I noticed that graphite particles were flaking off the electrodes in electrolyte solution during the experiment. The amounts of carbon particles lost from graphite were very less and so was neglected but later I thought that it might be affecting the result in some or the other way as in the experiment we were supposed to weigh the electrodes to find out the amount of Copper deposited on the cathode. I used to think that if graphite electrodes are themselves losing some mass, then how the electrode can give accurate readings or a reliable result. The copper deposit over cathode is not strongly attached to the cathode thus there are chances that copper deposited on cathode may be lost by mishandling of the electrode before taking direct mass reading; this made me think about an alternative method which would be more accurate as well as reliable, where in the electrodes will n ot have to be removed from the experimental set-up at all! 2. THEORY I would like to start by mention something about electromagnetic spectrum as my experiment deals with Beers law which can be obtained through absorbance value. Absorbance in the colorimeter is found by setting a particular wavelength and there is different wavelength for different objects, similarly there is a particular wavelength absorbed by CuSO4. Electromagnetic radiations have frequencies and all the possible frequencies are covered in the range known as electromagnetic spectrum. The property of characteristic distribution of electromagnetic radiation emitted or absorbed by any specific object is the electromagnetic spectrum of that object. Electromagnetic spectrum has its range from low frequencies which are used for modern radio to the high frequency like gamma radiation. It covers wavelength from thousand kilometers to small fraction. The limit for the long wavelength is the universe itself and shortest wavelength is near to the Plank length even if the principal states the s pectrum is infinite and continuous which is truly acceptable. In the Vernier colorimeter we have option to select the wavelength from range 430nm, 470nm, 565nm and 635nm. According to the user guide for Vernier colorimeter CuSO4 will yield a good Beers law curve at 635nm. Therefore it says that the wavelength absorbed by CuSO4 lies in the range 635nm and I had used 635nm range throughout the experiment for finding the absorbance of CuSO4. In the study of light we have the Beer-Lambert law which is also known as Beers law and the law is related to the absorption of light to the properties of the material from which the light passes. Electrolysis is a process to separate bonded elements and compounds .The methodology followed is by passing an electric current through bonded elements and compounds. Electric current is passed through a conductor called as electrode. Electrodes are found in various forms like wires, plates, and rods. Electrodes are mainly constructed of metal, such as copper, silver, lead, or zinc. Electrodes can also be made up of nonmetal substance, such as carbon. There are commonly used Graphite electrodes which are made up of carbon. In my experiments as I have used graphite electrodes, I am indirectly using nonmetal substance having carbon. Inert electrodes do not take part in the chemical reactions for Examples, Graphite and Platinum electrodes. Active electrodes take part in chemical reactions where the anode itself produces metal ions which get discharged at the cathode for Example, Copper electrodes. I noticed that graphite rod was losing carbon particles on stirring, thats the reason why direct method to find mass of copper deposited was not adopted by me. The electrodes which I used for the experiments were Inert electrodes and I used graphite electrodes because platinum electrodes were not available and they were costly. An electrode passes current between a metallic part and a nonmetallic part of an electrical circuit. Most frequently, conductors that are metallic carry electrical current. In other circuits, however, current is passed through a nonmetallic conductor. In an electrochemical cell, an electrode is called either an anode or a cathode. An anode is an electrode at which current leaves the cell and oxidation takes place. For example, an anode is the positive electrode in a storage battery. Faradays 1st Law of Electrolysis states that, The mass of a substance altered at an electrode during electrolysis is directly proportional to the quantity of electricity transferred at that electrode. Quantity of electricity refers to the quantity of electrical charge, typically measured in coulomb. Throughout the investigation I had rounded off few of the readings to get correct significant figures. Using a colorimeter: This method is only useful if one of the reactants or products is coloured. It is a more satisfactory method than titration for two reasons: firstly, no sampling is needed, and secondly, a reading can be taken almost instantaneously. So quite rapid reactions can be followed, especially if the colorimeter is interfaced to a data logger or computer which can plot a graph of concentration versus time as the reaction proceeds. A colorimeter consists of a light source with filters to select a suitable colour (i.e. set of wavelengths) of light which is absorbed by the sample. The light passes through the sample onto a detector whose output goes to a meter or a recording device. The colorimeter usually needs to be calibrated and even I calibrated the Vernier colorimeter with distilled water before conducting the experiments. Calibration is done to establish the relationship between its readings and the concentration of the copper sulfate used. 3. INVESTIGATION My investigation was divided into three main sections, starting with verification of Faradays First law of electrolysis, secondly to determine Avogadros number and finally in determining Faradays constant. I had predicted that the results of investigating Faradays First law by direct method and indirect method will give almost the same result and I was successful in getting that. But according to my assumptions, more accurate readings can be obtained by the indirect method of colorimeter using Beers law technique. It is also useful to determine Avogadros number and Faradays Constant as the result which I got through the Beers law technique was almost near to the true value of Avogadros number and Faradays constant. 3.1 APPARATUS AND MATERIALS Beakers (250 cm3 ÃÆ'- 1) Volumetric flask (100 cm3 ÃÆ'- 5 and 1000 cm3 ÃÆ'- 1) Measuring Cylinder (100 cm3 ÃÆ'- 1) Digital Weighing Balance Graphite electrodes Copper sulfate (CuSO4) Ammeter (0-500mA) Rheostat (0-500 à ¢Ã¢â¬Å¾Ã ¦) DC variable voltage source (0 12 V) Vernier labquest colorimeter Cuvette 3.2 CIRCUIT DIAGRAM OF EXPERIMENTAL SET UP The above shown diagram represents the electric circuit diagram of the entire experimental setup. A DC variable voltage source (0-12 V) was used as a battery. Rheostat was use to control the current coming from the battery because I was recording the Ammeter readings and I wanted the readings on the Ammeter to be constant throughout the experiment. I used Rheostat because the Ammeter reading was fluctuating and not remaining constant. The positive terminal of the battery was connected to the one end of Rheostat and the negative terminal of the battery was connected to the cathode. The connections were made in series as it was suppose to be for this experiment. The experimental set up was not disturbed during the electrolysis. During the investigation, there goes a chemical reaction within the experimental setup for the electrolysis of copper sulfate. Below are shown the reactions using graphite anode inert electrode. At cathode: Cu2+ + 2e- à ¢Ã¢â¬ ââ¬â¢ Cu At anode: OH1- 1e- à ¢Ã¢â¬ ââ¬â¢ OH x 2 [2OH à ¢Ã¢â¬ ââ¬â¢ H2O + [O] ] 4OH à ¢Ã¢â¬ ââ¬â¢ 2H2O + O2 Product at anode: Oxygen gas 3.3 PREPARATION OF SOLUTION Preparation of 1 dm-3 of reagents: The salt which I used in preparation of solutions was Copper sulfate pentahydrate, we commonly call it as copper sulfate. The molar mass of CuSO4.5H2O is 249.68 gmol-1. Therefore, to prepare a 1.000 molar of CuSO4 solution, I took 124.84 g of CuSO4 weighing upon a digital balance and then I diluted 124.84 g of CuSO4 in 500cm3 of distilled water. I had used distilled water to dilute the chemicals and to clean the apparatus rather using tap water because distilled water is more pure and using tap water can affect the result as it can indirectly react with the chemicals used for the experiments. It was very difficult to dissolve CuSO4 by using glass rod. Therefore, I had used magnetic stirrer to dissolve the crystals of Copper sulfate in distilled water. It was very time consuming in dissolving CuSO4 in distilled water but within few minutes the 500cm3 solution of 1.000 molar of CuSO4 was ready. From that 500cm3 of 1.000 molar of CuSO4, I prepared different 100cm3 solutions of concentration 0.8 molar, 0.6 molar, 0.4 molar and 0.2 molar. The volumes of Copper sulfate and Water in the different molar solutions are given in the below table: Concentration (Ãâà ±0.001 mol dm-3) Volume of CuSO4 (Ãâà ± 0.05 cm3) Volume of H2O (Ãâà ± 0.05 cm3) 1.0 mol dm-3 100 cm3 00 cm3 0.8 mol dm-3 80 cm3 20 cm3 0.6 mol dm-3 60 cm3 40 cm3 0.4 mol dm-3 40 cm3 60 cm3 0.2 mol dm-3 20 cm3 80 cm3 3.4 VERIFICATION OF BEERS LAW Beer in 1852 studied the effect of absorption of light on the concentration of solutions and found a similar relationship. Beers law states that when a parallel beam of monochromatic light enters an absorbing medium, the rate of decrease of intensity of the light with concentration is directly proportional to the intensity of radiation. Alternative statements can be expressed thus: When a parallel beam of monochromatic light passes through an absorbing medium, the intensity of transmitted radiation decreases exponentially as the concentration of the absorbing species increases arithmetically. Successive layers of equal concentration and thickness absorb equal fraction of incidental radiation. The readings for my Beers law experiments are as follows: Concentration (Ãâà ±0.001mol dm-3) Transmittance (%T) Absorbance (Ãâà ±0.001) 0.0 100.04 0.000 0.2 25.92 0.586 0.4 8.17 1.088 0.6 3.02 1.520 0.8 1.33 1.875 1.0 0.97 2.015 The graph which was obtained for Beers law: The graph was taken from vernier colorimeter using logger pro software to get the accurate readings for the absorbance of CuSO4. Here I observed a curve in graph and I felt that this abnormal for Beers law but later when I searched the reason for this, I got satisfactory answer as I was not gone wrong. Beers law is true for dilute solutions and therefore it is sure to obtain a straight line graph for dilute solutions. In the cases of highly concentrated solutions we get a curve which flatters if extended further due to the high concentration. This is the same case with my Beers law graph because the solution of CuSO4 was much concentrated. Deviations from Beer Lamberts Law: According to Beer-Lamberts law, absorbance A is directly proportional to concentration c. Thus, a graph of Absorbance v/s concentration should give a straight line passing through the origin. Often we find that the graph is not linear, and deviations occur. If the straight line curves upwards or downwards it indicates positive or negative deviations respectively from Beer Lamberts law. Deviations from Beer-Lamberts law a : no deviation; law is valid b : positive deviation c : negative deviation I got negative deviation for my Beers law graph. Negative deviation is shown in the above graph with option c. The Negative deviation in the graph was expected as the CuSO4 solution was highly concentrated. Deviations fromBeer-Lamberts law can be of three types: Real deviations: which are fundamental in nature. Instrumental deviations: which arise as a consequence of the manner in which the absorbance measurement is made. Chemical deviations: which arise as a result of chemical changes associated with concentration changes. The deviation which I got in my Beers law graph was Real Deviations and such deviation occurs due to Effect of concentration. The Beer-Lamberts law is valid for dilute solutions only. If the concentration of the solution is more than 0.01 M, Beer-Lamberts law does not strictly hold well, and deviations occur. At higher concentration, the molecules of the absorbing species come closer to one another, and due to this, charge distribution of neighboring molecules is affected. This results in an alteration in the ability of the species to absorb a particular wavelength of radiation. The extent of interaction depends on the concentration of the solution and therefore deviations are observed in concentrated solutions. The molar absorptivity à à · depends on the refractive index of the solution. If the solution is too concentrated it refractive index changes and thus à à · changes. This causes deviations from Beer-Lamberts law. This effect is negligible in concentrations

For this couple, the representative may suggest a product that combines insurance and investment such as an annuity or universal life insurance. The couple can establish a relationship with a financial services firm in a local branch or through an interactive website maintained by the company. In some cases the bank that they are already established with may have a financial planning division that they can access in the local branch or through the bank website. Scenario B The best financial institution for a student looking to establish a checking or saving account, establish credit, and develop a relationship with a financial institution should consider a credit union. A credit union is similar to a bank in that it offers deposit accounts and loan programs, but differs from banks in that credit unions are non-profit organizations that are owned and operated by members as opposed to being owned by stockholders and operated by executive boards. Credit unions generally offer higher interest rates on savings accounts, lower fees on checking accounts, and lower interest rates on loans and credit cards. Credit union membership is generally tied to an organization such as a labor union, many large corporations have employee credit unions, some churches or communities have credit unions for members. This student can establish a credit union relationship through parents or may become employed in a local business that offers credit union membership as an employee benefit. Organizations like the Credit Union National Association provides resources and information for consumers. Scenario C The best financial institution for a small business owner who needs multiple deposit and checking accounts, investment services, and access to branches in other cities should consider a national bank such as Bank of America that has branches nationwide as well as online account access. Bank of America, and similar national banks, offer online payroll processing, credit card processing for retailers, and provide businesses with the option of importing bank statement information into popular accounting software formats such as Quicken, QuickBooks, and Microsoft Money. National banks have departments dedicated to small business lending and offer various types of Small Business Administration (SBA) loans. They also have services to meet the needs of specialty industries including financing and leasing partnerships with auto dealers. The business owner can establish a relationship with a banking professional at a local branch or can establish accounts online. National banks generally have extensive, interactive websites which provide information and guidance on establishing the business banking relationship. References Ameriprise Financial.

Effects of advertising Essay
Advertisements are everywhere, traveling by all ways possible, infiltrating the privacy that every person holds important to themselves and their family. American Marketing Association defines advertising as ââ¬Å"the non-personal communication of information usually paid for and usually persuasive in nature about products, services or ideas by identified sponsors through the various media.â⬠Today, with the development of the technology and the diversity of the mass media, advertising has influenced us pervasively in our daily life. Advertising has been applied in most of fields in society such as economical advertisings, educational advertisings, political advertisings, and healthy advertisings, etc. Advertising is used to promote goods, services, images, and anything else that advertisers want to publicize. It is becoming a major part of mass media. We may view it positively; at other times we may just skip or ignore it. In order to attract audience, advertisers use various techniques on their advertisement to make people aware of the firmââ¬â¢s products, services, or brands. Although the methods used by advertisers are infinitely, they have a common goal to persuade those who may become their customers to buy their products. An excellent advertisement will create a deep impression on its potential customers through particular techniques. They deliver their advertisement through TV, radio, magazines and newspapers, internet, billboards, and other multi-media means. By advertising, individuals or companies are able to get more extra profits from their products, promote their products, and gain the most important purpose ââ¬â to sell. In many cases, there are some negative effects ââ¬â some annoying hindrances in our daily lives. It makes our nerves, distorts the truth, and adds to the cost of the product. Advertising is designed for one purpose ââ¬â to sell. To achieve this goal, advertisers are willing to stretch and distort the truth, just to convince people to buy their products. For example, an advertiserà may convince buyers to purchase their products by stating those have been tested and found superior. In reality, the products are not better than any other ââ¬â the tests themselves doubtlessly conducted by the promoting company ââ¬â conducted to ensure at least something is superior about the product, even if it is only the color. These advertisements are worded carefully so that they are telling the ââ¬Å"literal truthâ⬠ââ¬â the truth is exactly what the words say, although people misinterpret the message by using conversational logic as something different ââ¬â something better. By using ingenious tactics like these, the populace is deceived into buying a product that may not do what is required, or a product that a buyer may have never needed. That is why advertising is not good for our society. First, I would like to discuss about the negative effects to children and youth. One of the most corrupt forms of advertising comes from cigarette companies. According to some investigator, ââ¬Å"Cigarette advertisements are degrading not only because the products behind them are proven to be a health hazard, but also because the advertisements are focused toward younger generations.â⬠Many advertisements use young, attractive, healthy looking models when advertising for a brand of cigarettes or beer. Company promotions have led people to affiliate certain products with feelings of happiness or euphoria. There is no doubt that people smoke the most heavily advertised brands of cigarettes. ââ¬Å"Tobacco advertising increases young peopleââ¬â¢s risk of smoking by using themes that appeal to them, such as fun times, action, and being popular and attractive.â⬠(Family Education 1). Advertisings that supply the Surgeon Generalââ¬â¢s warning along with the main body of the message are blatantly contradictive. These advertisings prove that there are many forms of advertising without any morals, and that companies will go to great lengths to have their name and image promoted regardless of the results. The nationââ¬â¢s companies have put themselves before the children. Similar to the case of cigarette companies, Ph.D. Henry Saffer show that spending money to advertise alcohol contributes to increase the rate of students drinking. Alcohol remains popular with American college students, as indicated by the Core Institute Survey (1998). In 1997, 84.2% of college students reported drinking alcohol, an increase of 2% over the prior year. For comparison, there were similar increases in the prevalence of tobacco and marijuana use. Moderate to heavy drinking also increased with corresponding reductions in abstention and light drinking. Nationwide, students reported consuming an average of 5.64 drinks per week in 1997, up about 7% over 1996. The Core Institute also reported that 45.5% of students had consumed five or more drinks in one sitting in the previous 2 weeks. More than 21% of the students reported three or more episodes of this kind of high-risk drinking in the previous 2 weeks. Finally, more than 90% of American college students reported that drinking is a central part of campus social life. (Henry Saffer, Ph.D., Alcohol Advertising and Youth, pg. 173) According to Competitive Media Reporting, more than $1.2 billion was spent in 1998 on alcohol advertising in measured media (i.e., print media, outdoor advertising, radio and television). An additional two-thirds billion dollars was spent on other forms of promotion, including sponsorships, couponing and direct mail. Alcohol advertising had decreased from 1987 to 1996 by 34%, in real terms. However, since 1997, alcohol advertising has been increasing. Part of the recent increase includes the use of cable television by spirits advertisers. (Henry Saffer, Ph.D., Alcohol Advertising and Youth, pg. 173) Second, advertisements can change or impact an individualââ¬â¢s behavior, attitude, expectations, or relationships. The more advertising that a person watches the more that they are influenced by it. The more that they are influenced by advertising the less important their relationships become. Consequently, the behaviors that we display and the influences on our physical environment are directly affected by the amount of advertisements that we see. In the world of advertising, lovers are things and things are lovers (Kilbourne, Canââ¬â¢t Buy My Love: How advertising changes the way we think and feel, pg. 77). Sadly, advertising promotes a corrupt and bankrupt concept of relationships (Kilbourne, Canââ¬â¢t Buy My Love: How advertising changes the way we think and feel, pg. 77). It is unavoidable and extremely damaging to our relationships and especially families. With the divorce rate and domesticà violence rate at the highest it has ever been, it is necessary to evaluate the influences of advertising to our relationships. It has become more and more difficult to relate to our partners in a manner that isnââ¬â¢t objectifying and exploitative. These are images that are forced into our heads and we may have very little control over. Moreover, advertising creates images of what is appropriate behavior in a relationship, using products. That behavior is not always one that is idealistic for real life relationships and generally can be very damaging to intimate and personal relationships. Advertising plays a part in dictating our expectations of our mate, ranging from money and clothing to behavior and attitude. Therefore, when messages and images are repeatedly presented to us they inevitably have an impact on our relationships. Our intimate relationships have been trivialized and our relationships with products have become more important. Another negative effect is that some advertisings use the sexual content to attract the attention of consumers. Consistently, studies have demonstrated that sexual appeals attract attention to the advertising, typically without a corresponding advantage for brand information processing. Sexual content may be eye-catching and entertaining, but it may not be communicative and might distract the viewer from the message. Reichert, Heckler, and Jackson (2001) claim that when sexual stimulus is used in advertising, viewersââ¬â¢ perceptual and processing resources are directed toward the sexual information in the ad rather than toward the brand. Therefore, they will not have a perspicacious decision to buy the products. Recently days, on the television, some company try to develop the crazy adverting project that use womenââ¬â¢s belly to advertise. They make some small advertising boards and they paste them on the belly of women and then they ask them to wear short skirt and bikini, after that they will go around some public locations. In this case, it is very stupid that it can promote the womenââ¬â¢s body not the products. Finally, use sexual content to advertise is one of the negative effects of advertising that is worse in the society. Throughout history politicians have used various methods, such as persuasive speeches, political advertising and political rallies, to achieve their ââ¬Å"primary goal, the winning votesâ⬠. But according to the results of theà research made by Won Ho Chang (Professor and Director of the Stephenonson Research Center at the University of Missouriââ¬â¢s School of Journalism), Jae-Jin Park (Public Relation Specialist with LG Corporation in Seoul, Korea) and Sung Wook Shim (graduate student in the School of Journalism at the University of Missouri) in 1998 ââ¬Å"over the years, politicians have found that it is most advantageous to use political advertising to persuade votersâ⬠. For example, the majority of presidential campaigns depend on television advertising. Clinton spent $12 million of his $30.9 million limit on television commercials in the middle of the primaries, $42.4 million during reconvention, and $44 million on television ads in the general election. A total of $98.4 million was used on television commercials. In my opinion, it is not good for the citizens and will influence on the result of voting. The voters will receive much positive information of the politicians and they will be distracting the purpose of vote. Moreover, by using an effective political advertising, a politician can win the other politicians even though he is not as good as the others, and it is unfair to them. There are no a commission to check the information of political advertising that is wring or wrong; therefore, the voters will have no chance to predict what the politicians will do for them. Some politician just tries to get votes by any ways, and when they win they forget what they promise. In short, advertising in voting is not a good method and it also makes some disadvantage to both the politicians and the voters. The last problem is that some activities in our society are wrapped by the advertisings. On the streets of our city, many advertising billboards are built to advertise for some products and it makes he city become uncivilized. On the television, there are many programs of advertising that trouble the audiences. For example, when people are attracted by a wonderful program, some adverting programs are run and distract them. More over, on the Internet, now people get many difficulties to check their e-mail in the inbox because they have seen many advertising letter from some company in their inbox. In short, some of advertisings are now obstructing the process of some activities in our society. Advertising has a strong influence over social behaviors, attitudes, andà expectations of individuals involved in intimate relationships between men and women Companies spend millions of dollars on advertising every year. The companies are very aware of the effect of advertisement on the community. Companies would not spend millions of dollars on advertising if it had little or no effect on the public. We all know that advertising provides a general service of informing us about products. But, does it also unnecessarily affect our behavior, relationships, and environment? How can we avoid the negative effects of advertising, especially in our relationships? Nowadays, in order to promote the products, many companies abuse so much of the advertising. In this case, they do not pay enough attention to the quality and the value of the products. Therefore, although advertising can bring them the profit and promotion from selling their products, they have to consider some bad effects of them on the society.

Estella and Biddy as Opposites. essays
Estella and Biddy as Opposites. essays Biddy is Pips childhood tutor, friend and confidant. She is always the person he unloads onto; no one else is continually there for him. Perhaps Pip gets along so well with Biddy as they are both orphans. They have also both been brought up by hand, and know what it feels like to be unloved, and treated harshly. Mr Wopsles great-aunt raised Biddy, and she owned a little general shop, as well as the school Pip attended. Although she seemed to have owned so much, she was still considered low-class, possibly because she didnt know what stock her shop held, and that Pip didnt really learn anything from her. (She wasnt a good teacher, it was Biddy who taught Pip to read and write.) In Pips opinion, Biddy has very noticeable looks. Her hair always wanted brushing, her hands always wanted washing, and her shoes always wanted mending and pulling up at the heel. (Great Expectations, Chapter 7, page 42). Biddy is only a few years older then Pip. Estella is also an orphan, which is interesting, as this means the three characters (Pip, Biddy and Estella) have something in common. However, different from Pip and Biddys situations, Estella has been adopted by a rich, higher-class lady, Miss Havisham. The only reason Estellas past is forgotten is that no-one knows who Estellas parents are, or what social class they were part of. Miss Havisham suffers from being dumped on her wedding day, so many years ago. She repeatedly lives her wedding day over; nothing in the house has been changed since that day, even all the clocks were stopped. By adopting Estella, Miss Havisham now has a little girl to love and take care of, as well as someone to mould into a beautiful lady, with a respectable education and very refined tastes. Miss Havisham wants to take her revenge on the male species, for ruining her life, by raising Estella to have no feelings. Later in the novel we see that Estella fin...

Preeclampsia, Eclampsia, HELLP syndrome
Preeclampsia, Eclampsia, HELLP syndrome Free Online Research Papers Preeclampsia, Eclampsia and HELLP syndrome are all serious complications of pregnancy. Preeclampsia is characterized by hypertension, and Eclampsia is the worsening of Preeclampsia where the woman experiences convulsions or goes into a coma. HELLP syndrome is a severe form of Preeclampsia, characterized high blood pressure as well. Both of these Eclampsia and HELLP syndrome can stem from Preeclampsia but they can also come about on their own with out ever having had Preeclampsia. There is no way to prevent any of these diseases; you canââ¬â¢t eat something or take a prescription, or anything. The only known cure for theses diseases is delivery of the baby. The treatments for these diseases are mainly to keep the mother pregnant for as long as possible. With all of these diseases death of the mother or baby is a serious complication. Studies have shown that if the mother goes to her health care provider on all of her prenatal visits there is a better chance that the baby and the mother will have little or no adverse effects. Preeclampsia is a universal problem during pregnancy, affecting up to one in seven pregnant women around the world. This condition is defined by high blood pressure and extra protein in the urine after twenty weeks of pregnancy. It has other names such as toxemia, or pregnancy-induced hypertension. In the United States Preeclampsia is usually mild. But if not treated it can lead to serious complications and even death for the mother and the unborn baby. Globally, Preeclampsia and other high blood pressure disorders during pregnancy are a leading cause of maternal and infant death (Mayo Clinic, Sept. 2006). Preeclampsia is a condition in pregnant women or immediately after pregnancy that is a form of toxemia of pregnancy characterized by hypertension; a ââ¬Ëdiastolic blood pressure of at least 90 mm Hg or a systolic blood pressure of at least 140 mm Hg, or a rise in the former of at least 15mm Hg or in the latter of at least 30mm Hgââ¬â¢ (Am J Obstetric Gynecology, 1998), fluid retention (when fluid isnââ¬â¢t removed from the body tissues), and albuminuria (albumin found in the urine) sometimes progressing to Eclampsia. The exact cause of Preeclampsia is still a mystery, there have been numerous studies but all the theories are still un-proven; some of the theories are: genetic, dietary, vascular, and autoimmune factors (Am J Obstetric Gynecology, 1998). Preeclampsia is most common in women who are pregnant for the first time (nulliparity), pregnant teens, and women who are over 40 years of age. The biggest risk factor of Preeclampsia is merely to be pregnant. Other risk factors are history of high blood pressure before pregnancy, previous history of Preeclampsia, history of Preeclampsia in mother or sisters, black race, obesity before pregnancy, carrying more than one baby and history of diabetes, kidney disease, lupus or rheumatoid arthritis (The Cleveland Clinic Birthing Services, Department of Obstetrics and Gynecology, 2006). Signs and symptoms of Preeclampsia can be asymptomatic, which is the scariest because women diagnoses with Preeclampsia do not usually fell sick. A lot of the times women with this disease think the signs of it are normal pregnancy symptoms. The more obvious symptoms are high blood pressure (hypertension) and the presence of extra protein in the urine after twenty weeks of pregnancy. Other signs of Preeclampsia are not always as obvious and include severe headaches, changes in vision; temporary loss of vision, blurred vision or light sensitivity, upper abdominal pain that usually occurs under the ribs on the right side, unexplained anxiety, nausea and vomiting, dizziness, decreased urine output, blood in the urine, rapid heartbeat, ringing in the ears, and fever. Sudden weight gain such as more than two pounds a week or six pounds in a month is a common sign as well. Preeclampsia can also happen gradually or very sudden. It may occur during the last half of the pregnancy, during del ivery or even a few days after the baby is born (Mayo Clinic, Sept. 2006). Preeclampsia is usually diagnosed on scheduled prenatal blood pressure checks and urine tests. If the mother has one reading of a high blood pressure she may be asked to come in more often to check her blood pressure so she can be monitored more closely (Mayo Clinic, Sept. 2006). The protein test for urine is important and if the test comes back even 1+ on the dipstick of a clean catch the doctor may order a twenty four hour urine collection to determine whether there is protein leaking from the kidneys (Sarah Henry, 2004). Lab studies such as complete blood count (CBC), thrombocytopenia (disorder where there are not enough platelets), hemoconcentration (increased concentration of cells and solids in the blood), liver functions tests, serum cretonne (measures the amount of creatinine in the blood), uric acid (used to evaluate the blood) and elevated PT may be ran to see if the patient has Preeclampsia. The doctor may also order an ultrasonography for fetal assessment (Wagner, LK, Family Physician, 2004). Most women with Preeclampsia give birth to healthy babies. Complications that may occur are lack of blood flow to the placenta and the problem with that is the baby may receive less oxygen and nutrients, which can lead to slow growth, low birth weight, preterm still birth and placental abruption. Placental abruption is when the placenta separates from the inner wall of the uterus before delivery. If it is severe abruption it can cause heavy bleeding (which can be deadly for the mother and baby), HELLP syndrome and Eclampsia (Mayo Clinic, 2007). Other complications of Preeclampsia are abruption placentae disseminated intravascular coagulopathy, renal insufficiency or failure, Hemolysis, ventricular arrhythmia, elevated liver enzymes, low platelet count, cerebral hemorrhage, fetal growth retardation, and death of the mother and/or baby (Dawn C. Jung, 2006). Prevention of Preeclampsia is still not known, there are some things that may make it less likely to occur. The most important thing that can be done is to keep all prenatal appointments with the doctor, since the condition is usually most often detected during these visits. A good thing to do is for the mother to participate in her own care: fond out her usual blood pressure (before pregnancy) and then she should ask what her blood pressure is at each visit. Also she should ask if there is protein is her urine, if yes then how much (Sarah Henry, 2004)? There are currently no known treatments other then delivery of the baby. If the mother is near the end of her pregnancy the doctor may decide to put her on bed rest to give the baby more time to grow and mature. The rules for bed rest depend on each individualââ¬â¢s case. If it is a mild case the mother may be able to stay at home and monitor her own blood pressure as well as going to see her doctor a couple of times a week. The doctor will tell her how much she is able to get up and what her activities should include. The patient should be very clear on what her restrictions are. She should prepare her resting room, if she chooses to rest in her bedroom or living room, etc. she should have everything set up around her within reach. The hours in the day will seem very long so the patient should try and organize her day, set a routine, have specific times for television, reading, and even telephone use. It might be a good idea to stay on the same times for meals and bedtime. The l ast thing she could is to take up a hobby such as scrap booking, knitting, painting, etc. (Mayo Clinic, 2006). In more severe cases of Preeclampsia the mother may have to be on bed rest in the hospital. The patient may have to do stress tests or biophysical profiles to monitor the babyââ¬â¢s well being. If there is a low amount it is a sign that the blood supply to the baby is inadequate and the mother may have to deliver the baby. Most of the women who have Preeclampsia are closely monitored and their doctors will not let them go past their fortieth week of pregnancy because of the risks to the baby. The readiness of the cervix- whether itââ¬â¢s beginning to dilate, efface, or ripen may also be a determining factor on when the doctor will deliver the baby (Mayo Clinic, 2006). The doctor may have to induce labor or perform a caesarean section is the Preeclampsia is severe enough. It all depends on the health of the mother and the unborn baby. In cases like these the benefits of delivering the baby early are better then the risks of waiting. During the delivery the mother may be given magnesium sulfate intravenously to boost uterine blood flow and avoid seizures (Mayo Clinic, 2006). Corticosteroids may benefit the women with Preeclampsia. Powerful corticosteroid medications can temporarily improve liver and platelet functioning in women with severe Preeclampsia. These medications might be able to lengthen pregnancy in situations where the baby is to young for delivery in terms of gestational development. Corticosteroids may also be able to make the babyââ¬â¢s lungs more mature in as little as forty-eight hours (Mayo Clinic, 2006). The impact on the baby when the mother has Preeclampsia depends on the degree of severity of the disease. The most common impact is the baby will be undernourished as a result of utero-placental vascular insufficiency, which leads to growth retardation. The babyââ¬â¢s health as well as weight is compromised, leading to various degrees of fetal morbidity, and possibly fetal death (Alicia M. Lapidus, OBGYN, 1999). There have been long term follow up studies and the results are that the baby is more likely to develop hypertension, coronary artery disease, and diabetes when they become adults. Studies are still in progress on the impact of the fetus (Alicia M. Lapidus, OBGYN, 1999). Eclampsia is a complication of Preeclampsia and it comes from the Greek word ââ¬Å"ekâ⬠meaning ââ¬Å"outâ⬠and the Greek word ââ¬Å"lampeinâ⬠meaning ââ¬Å"to flashâ⬠, put the two words together and you get ââ¬Å"to flash outâ⬠(Med Friendly). Eclampsia is a life threatening condition of pregnancy. In some cases comas or seizures may be the first signs that are acknowledged in a woman already diagnosed with Preeclampsia (eMedicine Health, 2006). Eclampsia is not as common as Preeclampsia it occurs in about one of every two thousand to three thousand pregnancies (Dominic Marchiano, MD, 2004). Eclampsia like Preeclampsia is not well understood. It involves a multi-system complication of pregnancy that significantly contributes to maternal morbidity and mortality (BMJ, 2005). The systems included are the cardiovascular system (CVS), renal system, and the central nervous system (CNS) (Stephanie R. Fugate, DO, 2005). The CVS derangements caused Eclampsia include generalized vasospasm, which is a sudden constriction of an artery leading to a decrease in its width and in the amount of blood it can deliver. Increased peripheral vascular resistance, increased left ventricular stroke work index, decreased central venous pressure, and decreased pulmonary wedge pressure. Renal system includes decreased glomeruler filtration tare, decreased renal plasma flow, and decreased uric acid clearance. The central nervous system includes problems with cerebral edema and cerebral hemorrhage (Stephanie R. Fugate, DO, 2005). Signs of Eclampsia are seizures, severe agitation, and unconsciousness for an unpredictable period of time, possible musculoskeletal aches and pains after an event caused by trauma. Other signs are involuntary movements, the relaxation phase of deep-tendon reflexes may be longer, breathing may come to an end for brief periods, physical evidence of trauma may be eminent, and an eye examination may not retinal changes caused by hypertension. About twenty percent of women who have Eclampsia only have slight change in blood pressure, and that may be there only sign (Web MD, 2007). The risk of Eclampsia is random and is not always physical signs so the doctor may give an anticonvulsant medication during labor to prevent seizures. Magnesium sulfate is a common choice of doctors to help control seizures. Medications might be used to lower blood pressure during pregnancy and the goal is to manage the condition of the mother until she is at least thirty-six weeks pregnant. The condition will be resolved when the baby is delivered or shortly after (Dominic Marchiano, MD, 2004). There are no known treatments for Eclampsia. If possible the doctor wants to keep the mother pregnant for as long as possible, so he may decide to put her on bed rest. Delivery is the only known treatment for Eclampsia. Causes that the doctor may decide to induce the mother are; diastolic blood pressure is greater then 110mm Hg for a six hour period of time, persistent or severe headaches, stomach pain, abnormal liver function tests, rising serum creatinine, HELLP syndrome, fluid in the lungs (pulmonary edema), thrombocytopenia (an abnormal decrease in the number of platelets in the circulatory blood), abnormal fetal heart pattern, and failure of fetal growth that is obvious on the ultrasound (Dominic Marchiano, MD, 2004). The complications of Eclampsia are as many as fifty six percent of patients may have brief deficits, including loss of sight due to organic lesions in the visual cortex. Most women do not develop long-term abnormal conditions from eclamptic seizures, but their cases should be followed closely by their doctors for resolution of symptoms (Rosen P., 1998). Serious complications include liver failure, kidney failure, lung failure, bleeding of the brain, a build up of fluid in the lungs, and pneumonia (inflammation of the lungs due to infection). Other complications are Hemolysis (a break down of red blood cells with discharge of hemoglobin), hypofibrinogenemia (an abnormal deficiency of fibrinogen in the blood that causes bleeding to stop), bleeding in the retina (a delicate, multilayered, light sensitive membrane lining the inner eyeball and connected to the optic nerve to the brain), temporary blindness, and abrupt placentae; a sac-shaped organ that attaches the embryo or fetus to the uterus, which is when the placenta separates in pregnancy of twenty weeks or more. The placenta is important to the fetus because it is the organ which links the blood supply to the fetus and by which the baby can release wastes (Med Friendly, 2007). The most severe complication of Eclampsia is that the mother and/or baby die. About ten percent of the mothers die from this disease and thirty three to fifty percent of the babies die, typically because they are not getting enough oxygen. Characteristically, of these deaths about half take place before birth and the other half after birth (Med Friendly, 2007). The most serious complication of Preeclampsia besides death is the HELLP syndrome. H stands for Hemolysis (rupture of red blood cells); EL stands for Elevated Liver enzymes in the blood (reflecting liver damages); LP stands for Low blood levels of Platelets (specialized cells which are vital for normal clotting), in which there is a combined liver and blood clotting disorder. This condition occurs in mid-second trimester of pregnancy, and up to eight percent of women it occurs in is after the baby is born. The HELLP syndrome can also occur on its own, with out ever having Preeclampsia. Women who have this syndrome may have problems with bleeding, high blood pressure or liver problems that can hurt both the mother and/or the baby (Internet Health Library, 2005). Comparison of risk factors for the HELLP syndrome and Preeclampsia (Maureen Oââ¬â¢Hara Padden LCDR, MC, USN, 1999): HELLP Syndrome Preeclampsia Multiparous Nulliparous Maternal age greater than 25 years of age Maternal age less than 20 years or greater than45 years White race Family history of Preeclampsia History of poor pregnancy outcome Minimal prenatal care diabetes mellitusChronic hypertension Multiple gestation Any pregnant woman can get the HELLP syndrome. Most of the women who get this illness have high blood pressure, but this is not always the case. The most common people who get this are women who are white and over the age of 25, if they have had children previously or if there was a problem in a past pregnancy such as Preeclampsia (Maureen Oââ¬â¢Hara Padden, 1999). ââ¬ËKey abnormalities include vasoconstriction (constriction of a blood vessel), increased vascular tone, platelet aggregation (the attachment of platelets to one another) and an alteration of the thromboxane (any of several compounds, originally derived from prostaglandin precursors in platelets, that stimulate aggregation of platelets and constriction of blood) and prostacyclin (a prostaglandin produced in the walls of blood vessels that acts as a vasodilator and inhibits platelet aggregation) ratio. The changes can be partly explained by the activation of complement and the coagulation (process of clot formation) cascade causing multi-organ endothelial and micro vascular injury, and resulting in microangiopathic hemolytic anemia, elevated liver enzymes (periportal and hepatic necrosis) and thrombocytopenia.ââ¬â¢ (Egerman RS, Sibai BM, 1999) The most obvious signs of HELLP syndrome are nausea, epigastric pain (pain just below the ribs), or right upper quadrant pain (Sibai BM, 1993). Other symptoms include feeling tired and bad headaches. There may be swelling that occurs mostly in the face and hands, and on rare occasions bleeding from the gums and other places such as massive bleeding due to minor injuries (Maureen Oââ¬â¢Hara Padden, 1999). There are diagnostic tests that can be done to find out if the patient has the HELLP syndrome. The first is hematocrit; it may be decreased or normal and is the last of the three abnormalities to appear. If the finding of a serum haptoglobin level is decreased the mother will have to have continuing Hemolysis until the hematocrit is normal. The serum transaminase levels may be as high as four thousand U per L, but milder elevations are nothing out of the ordinary. The platelet counts can drop as sow as six thousand per mm3, but if there is any platelet count less then one hundred and fifty per mm3 to be watched by the doctor. The platelet count is the best way to recognize the HELLP syndrome. Laboratory abnormalities typically get worse after delivery of the baby and hit the highest point at twenty four to forty eight hours after the baby is born. The high levels of lactate dehydrogenase level signals the beginning changes for the better and successive normalization of the platelet c ount (Maureen Oââ¬â¢Hara Padden, LCDR, MC, USN, 1999). There are two classifications systems that are used to identify the HELLP syndrome. The first one is based on the number of abnormalities that are there. In this system this system the patients are classified as having partial HELLP syndrome, which is just one or two of the abnormalities. The class 2 HELLP syndromes are the full HELLP syndromes are at a greater risk of complications, which include DIC (disseminated intravascular coagulation), then the women with class one or partial HELLP syndrome. The patients with full HELLP syndrome should be considered for the delivery of the baby within forty-eight hours (Maureen Oââ¬â¢Hara Padden, LCDR, MC, USN, 1999). Typically in the past, the deliveries of patients with the HELLP syndrome were routinely proficient by a cesarean section (C-section). The patients that had the full HELLP syndrome superimposed DIC (disseminated intravascular coagulation), or a C-section then 32 weeks should deliver a gestation that is less. A trial labor is appropriate in patients that have mild to moderate HELLP syndrome and if they are stable, have an approving cervix and are at least 32 weeks pregnant (Maureen Oââ¬â¢Hara Padden, LCDR, MC, USN, 1999). The treatment of HELLP syndrome is determined by the physician and will be based on: your pregnancy and overall health and medical history, extent of the disease, the patients tolerance for specific medications, procedures and therapies, expectations for the course of the disease and the opinion of the patient. Treatments may include: bed rest, hospitalization because specialized personnel and equipment may be necessary, blood transfusions, magnesium sulfate, antihypertensive medications and fetal monitoring to check the health of the baby (UVa Health, 2006). The doctor may decide to check the baby while the mother is still pregnant, and these may include fetal movement count- keeping track of the babyââ¬â¢s kicks and movements. A change in this number or regularity might mean the baby is under stress. A nonstress testing, which is a test that combines nonstress testing with ultrasound to observe the baby. A Doppler flow study is a type of ultrasound that uses sound waves to measure the flow of blood through a blood vessel (UVa Health, 2006). The patients that are diagnosed with HELLP syndrome should be treated with corticosteroids regularly. The antenatal administration of dexamethasone (Decadron) in a high dosage of 10 mg through an IV every 12 hours has been shown to clearly make the laboratory abnormalities connected with the HELLP syndrome get better. The mothers treated with this drug show signs of longer time for delivery. Steroids that are sometimes given do not classically prevent the worsening of laboratory abnormalities after delivery; patients who get the steroids postpartum make the laboratory abnormalities resolve quicker. Patients should also be treated with magnesium sulfate to prevent one of the complications, which are seizures. If the patients blood pressure remains high (greater then 160/110 mm Hg) even after the magnesium sulfate is used they should use antihypertensive therapy. This will make the risk of maternal cerebral hemorrhage, placental abruption and seizures less likely to occur (Maureen Oâ⠬â¢Hara Padden, LCDR, MC, USN, 1999). The complications of HELLP syndrome are seizures, which occur as a result of restricted blood flow to the organs caused by high blood pressure Anemia, which is caused by the breakdown of red blood cells, problems with blood clotting, including Disseminated Intravascular Coagulation that cause internal hemorrhaging, placental abruption, difficulty breathing which can be caused by fluid buildup in the lungs. Then there is liver damage or failure, kidney damage or failure and stroke (Pregnancy info, 2007). Patients who have the HELLP syndrome are at a greater risk of danger then the babies. The compromised body functions can cause liver failure, heart failure or stroke. The babyââ¬â¢s health is threatened because the decline of blood flow can cause placental separation and lower birth weight, and because the baby ultimately will have to be delivered prematurely The greater part of babyââ¬â¢s born to mothers with this syndrome do very well (Christine Fisher Guy, 2005). If the baby weighs more then a thousand grams when they are born the survival weight and the time they stay at the hospital are similar to babyââ¬â¢s born at about the same birth weight to mothers that do not have the HELLP syndrome, and there are not usually any long term effects on the baby. If the baby weighs less then a thousand grams at birth the news is not as good. The studies that have been conducted have shown that the baby will probably have to stay in the hospital longer and may even have to be on a ventilator. The studies show that these smaller babies have a decreased chance of living compared to babies of the same birth weight to mothers with Eclampsia. The same studies declare that the prenatal mortality from HELLP syndrome ranges from 7.7 percent to 60 percent. The most common cause of these deaths is recognized by abruption of the placenta prematurely separating, intrauterine asphyxia (when the baby does not get enough oxygen), and extreme prematurity (HELLP syndr ome society, 2005). Prevention of the HELLP syndrome is not known at this time. The only thing the patient can do is to know the warning signs and to be well informed on them. The patient should also keep regular check ups with their health care provider, and if they get the HELLP syndrome they can receive treatment and hopefully try to prevent this disease from getting worse (UVa Health, 2006). The most common medical complication of pregnancy is hypertension. The women diagnosed with the HELLP syndrome, Eclampsia, and Preeclampsia presents a variety of management issues. Regardless of the diagnosis, severe Preeclampsia, the HELLP syndrome, or Eclampsia can intensely affect the woman and her unborn baby. The underlying pathophysiology must be evaluated and treated with both patients in mind at all times. The main goal for all of these diseases is to keep the mother pregnant for as long as possible. She may be given magnesium sulfate or an anticonvulsant to help her stay pregnant. Both the mother and baby will be closely monitored, and if the mother is close to the end of her pregnancy or if the baby is in distress the doctor may decide to induce labor or do a C-section. The most important thing is to make sure that both parties are doing well until the baby is delivered and they are both out of harms way.

Communicating effectively in obstetric emergencies Essay
Communicating effectively in obstetric emergencies - Essay Example The incompetent midwifery and lack of awareness can also contribute to the inadequate maternal facilities to the mother and the baby (Aljunid & Zwi, pp. 426-36, 1996). In many countries, specifically the Middle East and South Asian countries like India, Nepal, and Srilanka have low mortality rate that contributes to women preferring to give deliver in private or home by unofficial nurses or midwifery. The lack of awareness and proper maternal education can even result in serious healthcare problems to the mother and the child (Walsh, pp. 1-5, 2001). The intensive prenatal care facilitation in obstetric emergencies is highly regulated factor and there should be specific paramedical facilities available to manage such interventions such as forced or unwanted abortions complications, prolonged labor deliver, blood transfusion, and cesarean section. According to the estimates, 585,000 women die due to lack of effective communication by the skilled attendants and midwifery in pregnancy an d labor complications (WHO, pp. 20-42, 1996). The functional referral system of transporting midwifery services across the rural areas for stabilizing the obstetric emergencies and early diagnosis of complication in labor or pregnancies can resolve the mortality issues (O'Driscoll, pp. 39-41, 1994). The training of traditional birth attendants (TBAs) and midwives can effectively contribute to the immense action in the state of emergency as professional health armors to the delivering woman (Foord, pp. 10-29, 1995). Role of Midwife in Obstetric Emergencies as an Effective Communicator A person who has specific training and skills to work with the paramedical staff in obstetric emergencies during pregnancy and labor is termed as midwife. They have responsibility to provide utmost care to the newborn infants and detection of complications in case of emergent labor, eradicate the barrier in communication between the patient and the medical staff, and educate the mother for any preventiv e measures in case of any complications (ICM, pp. 56-79, 2005). The midwifery is a significant key player in reducing the risk of maternal death and immediate postpartum period. The appropriate facilitation of midwifery education and training, referral system, and positive support system to maternity care have regulated the expertise areas of midwifery profession in effective and immediate actions during the labor and pregnancy emergencies (Hogan et al., pp. 1609-23, 2010). The striking death toll for maternal death is due to in effective life saving techniques particularly in hemorrhage, obstructed labor, unsafe caesarian section, and abortions. The skilled midwives can provide utmost diligent care in the absence of a medical practitioner particularly in rural areas or private births. It could also accommodate to sufficient medical environmental care to the mother and the baby before and after the labor (Ronsmans & Graham, pp. 1189-1200, 2006). The literature revealed that lack of

Rule of St Benedict Essay Example | Topics and Well Written Essays - 2000 words
Rule of St Benedict - Essay Example The rule was authored to provide a guide for the formation of autonomous and individual communities, which Benedictine monasteries remain to this day. The emphasis laid on autonomy helped the monasteries to assume contemplative lifestyles and cultivate communities that were tightly bonded2. However, the monasteries also suffered from isolation from the communities that surrounded them, as well as increased inefficiency, declining appeal for potential recruits, and decreased mobility in serving others. Over the centuries, different emphasis on the rules led to the divergence of Ancient Observance, Cistercian Common Orders, and the Benedictine Confederation. St. Benedict, however, did not author the rules in a vacuum and it is evident that his work was heavily influenced by fading Athenian and Hebrew traditions present in medieval Europe at the time3. While this does not mean the rule was a throwback to the ancient times, there are various similarities. This paper seeks to compare the power relations and hierarchical structures in the early Benedictine monasteries and the governing of secular society at the time. The Benedictine Monastery as a Microcosm of Society as a Whole The Benedictine monastery under the Rule of St. ... Similar to the society in which he lived, St. Benedict ordered that the monks were to eat two cooked dishes of food at every meal, as well as a pound of bread daily. In the summer, he insisted on two meals and one in the winter, which was the same thing that peasants did due to the scarcity of food in the winter. The monks were also ordered to retire to their boarding rooms for six to eight hours every evening, which is the same as peasants who were not supposed to wander around the towns at night5. The Rule of St. Benedict also perceived the need for government in a uniform and permanent form, rather than the variable and arbitrary models used by other monasteries before his6. This led to a form of collectivism that was no different to society as a whole. The rule insisted on a common life compared to the solitary life led by Egyptian monks. In furthering his aim, St. Benedict also introduced into his rule the vow of stability, which was to become the basis of the orderââ¬â¢s per manence and success. This is just one example of his idea of the family as practiced in society that pervades the rule. Family ties bounded the members of his monastery, just like in society. In addition, the members of this family took upon the obligation of preserving the family, in this case the monastery, until they died. This aspect of the rule secured the community, as it did the family in society, with all member monks sharing in the fruits that arose from each of the monkââ¬â¢s labor. It also gave the monks the strength that comes from being part of a united family pursuing similar ends, which, in the case of society, meant subsistence farming and hunting. Therefore, like the defining Hebrew and Athenian society that was present at the time, the monks were part of a
