FAA - Before and After free essay sample

This paper takes a look at the FAA and its role before and after the Sept 11th attacks This paper provides a detailed look at the FAA and its role in the Sept 11th terrorist attack aftermath. It gives a history of the establishment of this institution and asks how it will have to change to cope with the post Sept 11th reality. From the paper: According to James Q. Wilson, ?War is the greatest test of a bureaucratic organization.? (Wilson, 1989, p. 45). He was of course speaking of the difficulties of leading soldiers into battle, but on September 11, airline pilots, air traffic controllers and the Federal Aviation Administration were on the front lines of a new kind of war. This essay will consider the FAA under this time of stress and rapid change.

6 Fast-Growing Healthcare Jobs for 2015 and Beyond

6 Fast-Growing Healthcare Jobs for 2015 and Beyond The healthcare industry is poised for tremendous growth in the years ahead thanks to the influx of insured Americans through the Affordable Care Act as well as the aging Baby Boomer population. Based on figures from the United State Department of Labor’s Bureau of Labor Statics, those looking for careers with unprecedented job security and potential for growth need look no further than these six healthcare jobs. 1. Registered NursesRNs are responsible for a broad spectrum of patient care duties, including everything from medical tasks to emotional support for patients and their families. RNS work in a variety of healthcare settings, including hospitals, nursing care facilities, physicians’ offices, schools, prisons, and in-home healthcare.There are a few different pathways to becoming an RN. Many people opt to pursue a bachelor’s degree in the field; associate’s degrees in nursing are also offered, as are diploma programs. Regardless of the type of nursin g degree, all RNs must be licensed.According to the BLS, RNs earn a median annual wage of more than $65,000. These salaries are likely to rise in the years ahead as demand grows. Just how strong is the outlook for these healthcare professionals? Employment is projected to skyrocket by 19 percent by 2022.2. Home Health AidesAs demand for health care services continues to increase, home health aides will fill an important void. These trained professionals provide assistance to people who suffer from chronic illness or cognitive impairment; they also help seniors and people with disabilities. Home health aides, who work in a multitude of different settings, require no formal training although most do have high school degrees. However, those working in specific settings - such as for hospice agencies - may require formal training and testing.While home health aides earn an average of nearly $21,000 a year, this may change with demand. In fact, the employment of home health aides is e xpected to grow by a whopping 48 percent between now and 2022 - significantly outpacing the average for all occupations.3. Nursing AssistantsNursing assistants, also called orderlies, provide basic patient care in settings ranging from hospitals to nursing homes. They are required by their states to complete an education program, and must also pass a competency exam in order to become certified. The average annual pay for nursing assistants and orderlies hovers around $24,000, according to the BLS. As the elderly population continues to grow, the need for these skilled professionals will correlate. Experts predict 21 percent employment growth between now and 2022.4. Medical SecretariesMedical secretaries perform basic administrative duties in a healthcare setting. This typically requires specific knowledge of medical terminology and procedures; additional duties may include everything from billing patients to scheduling appointments. Occasionally, medical secretaries also take med ical histories, order supplies, and assist patients. According to the BLS, the median salary of a medical secretary is currently just under $32,000 although salaries can reach as high as $46,420. Even more noteworthy? Jobs for medical secretaries will experience a staggering 36 percent increase by 2022.5. Licensed Practical and Licensed Vocational NursesAlso known as LPNs and LVNs, these skilled healthcare professional work under the direction of doctors and RNs while providing basic patient care, such as checking blood pressure, changing bandages, inserting catheters, and offering basic care and comfort. Work environments are diverse, and range from hospitals to private homes. In addition to licensure, both LPNs and LVNs require the completion of a one-year state-approved educational program.According to the BLS, LPNs and LVNs earn a median annual pay of just over $41,500. Between 2012 and 2022, jobs are expected to grow by as much as 25 percent thanks to increases in chronic condi tions among the aging population.6. Medical AssistantsMedical assistants are responsible for a number of different clinical and administrative tasks in healthcare settings. The specifics of the role, however, vary depending on the specialty, location and size of practice. While it’s possible to become a medical assistant with a high school degree, most at least have a certificate. Others learn through on-the-job training opportunities. While the average salary for medical assistants is $29,370, a growth rate of 29 percent between 2012 and 2022 may lead to greater demand as well as higher salaries.The healthcare system is currently facing many uncertainties, but one fact is very clear: educated and experienced healthcare workers will deliver much-needed skills in the evolving landscape of the American healthcare system.

Software Application life-cycle Research Paper Example | Topics and Well Written Essays - 750 words

Software Application life-cycle - Research Paper Example It also depends upon the time and budget constraints of which of the life-cycle model will be appropriate to adapt. This paper will introduce and compare two of the life cycle models; the waterfall and the agile model. The models will be compared and analyzed in the context of the mobile software development project. This is to propose the most adequate model for a mobile software development project (Schach, 2010). Comparative Analysis of Life-Cycle Models The waterfall life cycle model is a sequential process model. It is a step-by-step development model starting from the initial design phase and ending to the completion phase (the maintenance phase) (Schach, 2010, p. 53). The phases of the model are interdependent on each other as the next phase begins only when the previous phase is ideally completed. Adapting waterfall model for the mobile software development project could be worth it as it may include the detailed stages of requirements analysis, design, and implementation, gi ving ideal completion to the mobile software (Munassar & Govardhan, 2010). Contrary to the waterfall model is the iterative incremental life cycle model, which is based on correspondence and integration (Bittner & Spence, 2006, p. 143). The iteration model leads a mobile project incrementally, which means that it has more compatibility that the waterfall method to adapt changes in the initial requirements’ stage. It is a reversible model looped to the adjusting and modifying code source requirements (Gomaa, 2011). The waterfall life cycle model is a more detailed and apprehensive model for mobile software development (Mall, 2009). It is a more comprehensive model than iteration to complete a mobile development project. However, it could be more expensive than the iteration model as it is less flexible to adapt changes. The rigidity of the model is what makes it a more complex model to adapt (Schach, 2010). Iterative incremental model is more flexible as compare to the waterfa ll model. More specifically, for the short term mobile projects, iteration model is supple to adapt. The mobile software development often requires changes in each development stage (Schach, 2010). Likewise, there are feedback inputs from stakeholders or users that could come at the beginning or at mid or ending stages of design and implementation. This requires incorporation of the design changes or requirements changes, on where iterative incremental model is more effective to adjust (Schach, 2010). Due to sequential rigidity, the waterfall life cycle model gives less space to the mobile clients. It gives less room to the customers to assert their initial requirements (Schach, 2010). On the other side, iterative incremental model gives much choice to users to put on their initial requirements. As the iterative model affords the low cost on changes or modification so it allows users to give major demands or requirements. This is how iteration model is more market oriented than wate rfall. It is a model which is customer focused than waterfall model (Gomaa, 2011). The waterfall lifecycle model can take more time than iteration model to complete a mobile software project (Munassar & Govardhan, 2010). Comparatively the waterfall model requires larger set of data than iteration in proceeding and completing a project. As each phase is more detailed and more apprehensive so it makes the waterfall model a time consuming model (Mall, 2009). Apart from all, iterative increme

Sex and gender are both social constructions. Discuss Essay

Sex and gender are both social constructions. Discuss - Essay Example To achieve this, people invest the item with value, which every person acknowledge (therefore acting as though it has significance), and this explains people’s practices where money is concerned. However, currency is not just a thing, which occurs autonomously of human doings in the real world. In consequence, money is a social construction and a concept. It is incredibly real - calling money a social construct does not make it non-existent or imaginary. Nevertheless, its actuality is reliant on our ethnicity practices as well as our culture. This denotes that its classification, meaning, use and value are completely contingent on ethnicity. This paper will discuss sex and gender as social constructions. As society’s culture transmutes, so do their constructs. Certain constructs develop and then plunge into abandonment, and therefore, grow out of subsistence. Others remain; however, they vary from one civilization and historical episode to another. Sex and gender are su ch constructs. The behaviours and traits, which are believed to be feminine and masculine, differ vividly from one ethnicity and time interlude to another. Suitable ways of conduct oneself, the labour, which is allotted to gender sets, beliefs concerning natural talents and predispositions change drastically (Butler 2008). In addition, this adaptation and variation to circumstances, as well as social pressures underpins the notion that gender and sex are social constructions instead of some kind of essence, which begins from biology. Since if gender were shaped through physical sex, it would never change in this manner, but would be constant, simply as other naturally determined traits remain constant. Hence, gender differs with cultural transformation (Butler 2008). Gender is designated at birth rendering to bodily sex. Medical specialists inspect the infant's genitals and proclaim that the infant is a girl or a boy (except in the case where the new-born is intersex, where much eff ort is made to compel the kid into one faction or another). At that moment, the work inaugurates to fraternise the kid and impart the script, which matches with the gender that they have been allocated. In addition, most of people become pretty good on performing the fitting script. People learn which sentiments they are expected to exhibit, which undertakings they are expected to relish and shine at, as well as which ones they are expected to avoid. People also learn how to converse with one another, how to control their body language, and which type of hobbies and work they are expected to pursue. For many people it is not an appropriate fit, but people manage, or they learn ways of making those qualities about themselves, which do not match the script less visible. Nevertheless, for some people, it feels erroneous enough that they cannot just fit. For gender queer and trans gender,an individual, acting the new script or even an altered script completely, is the lone technique to render life liveable (Jackson, Steve & Sue 2006). Therefore, this description provokes a few queries such as why there exist only and why people require these scripts. People require the scripts as well as the evidently delineated categorical differences, because people cannot design hierarchy without variance. Hierarchy hinges on difference, therefore, people pick some physical

Human Cloning Research Paper Example | Topics and Well Written Essays - 1500 words

Human Cloning - Research Paper Example Besides therapeutic and reproductive cloning another category of cloning called the replacement cloning is also gaining prevalence. Replacement cloning is an amalgamation of therapeutic as well as reproductive cloning. The term gained prominence as it involves comprehensively injured, abortive, or weakening body, and replacement of the whole or partial organ or part of the body. The present article discusses the pros and cons of human cloning while extracting attention to understand the significance of human cloning in the advancement of human civilization. Introduction Human cloning is the process of generating a genetically indistinguishable replica of human being. The process is thought to be of therapeutic or reproductive importance. Therapeutic cloning encompasses cloning cells for their exploitation in treating various ailments. On the other hand reproductive cloning generates human clones, this is prohibited in many nations because of ethical concerns. The moral predicament of human cloning lies on the argument either to promote or to impede cloning (Human cloning). The Problems/Dangers and Controversies of Cloning Cloning is discouraged by various nations as cloning is against the rule of nature, which is generating humans, nurturing them and paving the way for uncertainties related with the repercussions of science. At present human population has crossed the figure of 7 billion, a huge burden on the planet. Is cloning going to resolve the issue of exponentially increasing human population is a big question imposed by the detractors of human cloning (Disadvantages of cloning). Considering the previous failures that involved Dolly experiments, uncertainty of science technology is mounting. Detractors of human cloning have their say about the loss of genetic diversity leading to higher probability and pervasiveness of genetic diseases. Poor adaptability of clones may become detrimental for situations of jeopardy. Inbreeding leads to self-annihilation. Cl oning is inhumane as it abolish the bond of love and care and is said to be transgressing the nature. The process of cloning highlight that the human or scientists can play the role of Creator or God as cloning is a kind of asexual reproduction, therefore reduces the sense of distinctiveness of a character, lacking uniqueness and freedom (Disadvantages of cloning; Williamson, 1999). Morally it is not supported by the opponents as they believe that human beings cannot take the laws of mother nature in hand and one cannot play the role of the Creator, God of the universe. For therapeutic use also if embryonic stem cells are being used, it is an eventual process of killing the embryo (Ethical Dilemmas of Cloning). It is also noteworthy to have an insight regarding the amplification in human population and ecological burden on resources and on other surviving species. Growing population is putting pressure on the demands of basic amenities, infrastructures and social set ups; with human cloning, further contribution to disaster cannot be eluded (Disadvantages of cloning). According to Savulescu (1999), human cloning is accountable to abuse, a person's right to individualism and self-sufficiency and being self is violated, moreover genetic individuality is also lost and human beings are used as a model organism.

Computer Networks And Wireless Transmissions

Computer Networks And Wireless Transmissions In telecommunications, wireless communication may be used to transfer information over short distances or long distance. The term is often shortened to wireless. it encompasses various types of fixed , mobile, cellular telephones etc. now -a days people who need to be online all the time. For these mobile users, twisted pair, coax, and fiber optics are of no use. They need to get their hits of data for their laptop, notebooks, shirt pocket or wrist watch computers without being tethered to the terrestrial communication infrastructure. For these users, wireless communication is the answer. THE ELECTROMAGNETIC SPECTRUM Wireless transmission can provide special services and conveniences to people, such as connection to the internet or other networks without connecting to wire directly. It can also facilitate the creation of networks in special situations, such as terrain that is unfriendly to ground cables. Wireless communication began, in fact, in the Hawaiian island precisely the problem of terrain separated by large stretched of ocean. Political organizations determine which sections of the spectrum of light are all to which wireless transmission purpose. Because the existing organizations are always in agreement with current practice or with each other, some products manufactured for one country may not work in another. RADIO TRANSMISSION Radio waves are easy to generate and are omnidirectional, but have low transmission rates. Also, depending on their frequency, radio waves either cannot travel very far, or are absorbed by the earth. In some cases, though, high frequency waves are reflected back to earth by the ionosphere. Ionosphere is a layer of the atmosphere. MICROWAVE TRANSMISSION Microwave transmission is popular for its ability to travel in straight lines. A source can be directly focused on its destination without interfering with neighboring transmissions. Because they travel in straight lines, though, the curvature of the earth can interfere with the microwave transmitters. The solution to this is the addition of repeaters in between the source and destination to redirect the data path. Microwaves are used for long distance communication like cellular phones, garage door openers and so on.. INFRARED AND MILLIMETER WAVES Infrared light is used for close- range communication, such as remote controls, because if does not pass through objects well. This is also a plus because infrared communications in one room de not interfere with the infrared communications in another room. Infrared communication is more secure than other option, such as radio, but it cannot be used outside due to interference by the sun. LIGHTWAVE TRANSMISSION Lasers can be used for wireless communication. It is a relatively low cost way to connect two buildings LAN, but it has drawbacks. The laser is difficult to target on the destinations receiver because the beam is so small. Laser light also diffuses easily in poor atmospheric conditions like rain, fog and so on. TERMS OF WIRELESS TRANSMISSION The theoretical basis for data communication Transmission media Wireless transmission The telephone system Narrowband ISDN Broadband ISDN and ATM THE THEORETICAL BASIS FOR DATA COMMUNICATION Harmonics An infinite series, such as a Fourier series, is just the addition of an infinite number of terms. Each term is called a harmonic. Baud Signals are used to send data over a write. If we want to indicate a data change, there is a corresponding signal change on the wire. The maximum possible number of signal changes per second is called the baud. Fourier Series A periodic function is one that repeats itself over time. Sine and cosine are periodic functions. Fourier proved that any reasonably behaved periodic function could be written as a sum of sine and cosine functions. This is important because sine and cosine are easily represented and recreated. The Fourier series allows periodic signals to be sent over a wire. Voice-Grade Line A voice-grade line has certain restrictions that limits the maximum number of signal changes per second. Signal-To-Noise Ratio Decibels A way to measure to measure the thermal noise that is present on a wire. TRANSMISSION MEDIA Here more than ten terms are there so I am going to explain five terms: Magnetic Media Material on which to store data. It is used in diskettes and magnetic tape. Magnetic media is a common way to transport data quickly. Twisted Pair The oldest and still most common transmission medium. Two insulated copper wires. Twisting the wires reduces electrical interferences from nearby wires. It also counters the antenna effect caused by parallel wires. Head-End In a dual cable system, there are two cables which only transmit data in one direction each. At one end of the network, data is collection from one line for re-transmission on the line going the opposite direction. The end of the network responsible for the data collection and retransmission is called the head-end. Subsplit When two cables are not used, but there is need for simulation of dual cable system, bandwidth on a single cable can be split up, with one portion representing one cable, and the other portion representing the second cable. Splitting the frequencies so that the lower frequencies are used for one purpose and the higher for another is called a subsplit system. Mode Characteristic of a light wave associated with the reflection of the wave through the silica fiber. WIRELESS TRANSMISSION Frequency (F) Light and electricity travel in the form of waves. Waves are periodic in that they repeat themselves, so the frequency of a wave is just the number of times the wave repeats itself in one second. Hertz (Hz) The unit of measure of frequency. The name comes from the german physicist who first produced electromagnetic waves. Wavelength (Lambda) Wavelength is the measure of the length of a wave that is it is used ti find the distance between two consecutive maxima or minima. Speed Of Light (C) The speed that electromagnetic waves travel in a vacuum approximately 3*108 m/sec. electromagnetic waves do not travel as fast through a medium as they do through a vacuum. Spread Spectrum A pattern for EM transmission which is popular in the military for its ability to avoid jamming. The transmitter hops from frequency to frequency across a wide frequency band. THE TELEPHONE SYSTEM In this there are more than ten terms so here I am going to explain six terms Public Switched Telephone Network The currently existing network used for telephone communication. It was designed specifically for voice, and is not well suited for use by computers for transmitting data to one another. End Office The place to which your telephones lines connect to receive the telephone service. The distance from the telephone to the end office is usually small around 1 to 10km). Toll Offices Switching centers that connect several end offices. Tandem Offices Similar to the toll office, except it connects the end offices that are within the same local area. Toll Connecting Trunks The hardware which connects the end office to the toll of offices. NARROWBAND ISDN Integrated Services Digital Network Fully digital, circuit switched telephone system that is designed to accommodate both voice and data services. Digital Bit Pipe A bi-directional logical pipe which will pass bits on from source to destination without concern about whether they are voice. NT1 Device placed between the user and the nearest end office allows ISDN connection. Plain Old Telephone Exchange or NT2 Device placed between the end user which can provide a variety of ISDN services. Narrowband ISDN ISDN services on 64-kbps channels. BROADBAND ISDN AND ATM Broadband ISDN It is more recent design for a digital network on which data can travel rates of 155Mbps. It is based on ATM technology. Permanent Virtual Circuits Virtual circuits that remains in place for extended periods of time. Switched Virtual Circuits Virtual circuits that remains in place for short periods of time, typically related to the session time. Head-Of-Line Blocking If a questionable cell tries to come into ATM switch, it will be stalled, effectively stalling the cells behind it unfairly. This is called head-of -line blocking. Knockout Switch To solve the head-of-line blocking problem, queuing on the output side has been proposed. The knockout switch does just this, by stimulating a single output queue by having several output queues that are activated on a round- robin type basis. FORMULAE THE THEORETICAL BASIS FOR DATA COMMUNICATION Baud Rate The baud rate is NOT the same as the data rate. Baud tells how many signals are sent per second, but there are ways of encoding more than one bit per signal change. AVOID getting this confused. Baud= number of signal changes/second Maximum Data Rate Of A Channel (Nyquists Theorem) Max data rate=2 Hlog2 V H=bandwidth in HZ V=discrete levels This formula shows the maximum number of bits that can be sent per second on a data line with a bandwidth of H, is V bits are sent per signal. The max data rate should be in bits per second. Signal-To-Noise Ratio 10log10(S/N) S=signal power N=noise power This formula is used to quantify the quality of a line. It is not usually presented as a ratio, but instead it is given in the units decibels. Maximum Number of Bits Per Second (Shannons Result) Max number of bits per second=H log2 (1+(S/N)) This formula shows the maximum achievable data rate on a noisy line. The difference between shannons result and Nyquists theorem is that Shannons result takes the noise on a line into consideration. The noise can drastically reduce a lines capacity to send data. It is measured in bits per second. TRANSMISSION MEDIA Attenuation 10 log10 (transmitted power/ received power) Attenuation is a way to measure the amount of power lost in a signals strength from when it was sent to when it was received. Attenuation is measured in decibels. WIRELESS TRANSMISSION This formula is used to find the relationship between frequency, wavelength, and the speed of light. Lambda f=c Lambda=wavelength F=frequency C=speed of light THE TELEPHONE SYSTEM This formula is used to fine the bits per second. Bits per second= number of bits per signal change*baud.

Organic food Essay

We asked Food Scientists a simple question: â€Å"What foods do you avoid? Experts from different areas of specialty explain why they won’t eat these eight foods. Food scientists are shedding light on items loaded with toxins and chemicals–and simple swaps for a cleaner diet and supersized health. Experts from different areas of specialty explain why they won’t eat these eight foods. Clean eating means choosing fruits, vegetables, and meats that are raised, grown, and sold with minimal processing. Often they’re organic, and rarely (if ever) should they contain additives. But in some cases, the methods of today’s food producers are neither clean nor sustainable. The result is damage to our health, the environment, or both. So we decided to take a fresh look at food through the eyes of the people who spend their lives uncovering what’s safe–or not–to eat. † Their answers don’t necessarily make up a â€Å"banned foods† list. But reaching for the suggested alternatives might bring you better health–and peace of mind. 1. The Endocrinologist Won’t Eat: Canned Tomatoes Fredrick Vom Saal, is an endocrinologist at the University of Missouri who studies bisphenol-A. The problem: The resin linings of tin cans contain bisphenol-A, a synthetic estrogen that has been linked to ailments ranging from reproductive problems to heart disease, diabetes, and obesity. Unfortunately, acidity (a prominent characteristic of tomatoes) causes BPA to leach into your food. Studies show that the BPA in most people’s body exceeds the amount that suppresses sperm production or causes chromosomal damage to the eggs of animals. â€Å"You can get 50 mcg of BPA per liter out of a tomato can, and that’s a level that is going to impact people, particularly the young,† says vom Saal. â€Å"I won’t go near canned tomatoes. † The solution: Choose tomatoes in glass bottles (which do not need resin linings), such as the brands Bionaturae and Coluccio. You can also get several types in Tetra Pak boxes, likeTrader Joe’s and Pomi. Exposure to BPA Causes Permanent Damage In OffSpring 2. The Farmer Won’t Eat: Corn-Fed Beef Joel Salatin is co-owner of Polyface Farms and author of half a dozen books on sustainable farming. The problem: Cattle evolved to eat grass, not grains. But farmers today feed their animals corn and soybeans, which fatten up the animals faster for slaughter. But more money for cattle farmers (and lower prices at the grocery store) means a lot less nutrition for us. A recent comprehensive study conducted by the USDA and researchers from Clemson University found that compared with corn-fed beef, grass-fed beef is higher in beta-carotene, vitamin E, omega-3s, conjugated linoleic acid (CLA), calcium, magnesium, and potassium; lower in inflammatory omega-6s; and lower in saturated fats that have been linked to heart disease. â€Å"We need to respect the fact that cows are herbivores, and that does not mean feeding them corn and chicken manure,† says Salatin. The solution: Buy grass-fed beef, which can be found at specialty grocers, farmers markets, and nationally at Whole Foods. It’s usually labeled because it demands a premium, but if you don’t see it, ask your butcher. 3. The Toxicologist Won’t Eat: Microwave Popcorn Olga Naidenko, is a senior scientist for the Environmental Working Group. The problem: Chemicals, including perfluorooctanoic acid (PFOA), in the lining of the bag, are part of a class of compounds that may be linked to infertility in humans, according to a recent study from UCLA. In animal testing, the chemicals cause liver, testicular, and pancreatic cancer. Studies show that microwaving causes the chemicals to vaporize–and migrate into your popcorn. â€Å"They stay in your body for years and accumulate there,† says Naidenko, which is why researchers worry that levels in humans could approach the amounts causing cancers in laboratory animals. DuPont and other manufacturers have promised to phase out PFOA by 2015 under a voluntary EPA plan, but millions of bags of popcorn will be sold between now and then. The solution: Pop organic kernels the old-fashioned way: in a skillet. For flavorings, you can add real butter or dried seasonings, such as dillweed, vegetable flakes, or soup mix. Make it organic and use coconut oil. If You’re Still Eating Microwave Popcorn, You’re Not Fully Grasping The Health Consequences 4. The Farm Director Won’t Eat: Nonorganic Potatoes Jeffrey Moyer is the chair of the National Organic Standards Board. The problem: Root vegetables absorb herbicides, pesticides, and fungicides that wind up in soil. In the case of potatoes–the nation’s most popular vegetable–they’re treated with fungicides during the growing season, then sprayed with herbicides to kill off the fibrous vines before harvesting. After they’re dug up, the potatoes are treated yet again to prevent them from sprouting. â€Å"Try this experiment: Buy a conventional potato in a store, and try to get it to sprout. It won’t,† says Moyer, who is also farm director of the Rodale Institute (also owned by Rodale Inc. , the publisher of Prevention). â€Å"I’ve talked with potato growers who say point-blank they would never eat the potatoes they sell. They have separate plots where they grow potatoes for themselves without all the chemicals. † The solution: Buy organic potatoes. Washing isn’t good enough if you’re trying to remove chemicals that have been absorbed into the flesh. Budget tip: Organic potatoes are only $1 to $2 a pound, slightly more expensive than conventional spuds. 5. The Fisheries Expert Won’t Eat: Farmed Salmon Dr. David Carpenter, director of the Institute for Health and the Environment at the University at Albany, published a major study in the journal Science on contamination in fish. The problem: Nature didn’t intend for salmon to be crammed into pens and fed soy, poultry litter, and hydrolyzed chicken feathers. As a result, farmed salmon is lower in vitamin D and higher in contaminants, including carcinogens, PCBs, brominated flame retardants, and pesticides such as dioxin and DDT. According to Carpenter, the most contaminated fish come from Northern Europe, which can be found on American menus. â€Å"You could eat one of these salmon dinners every 5 months without increasing your risk of cancer,† says Carpenter, whose 2004 fish contamination study got broad media attention. â€Å"It’s that bad. † Preliminary science has also linked DDT to diabetes and obesity, but some nutritionists believe the benefits of omega-3s outweigh the risks. There is also concern about the high level of antibiotics and pesticides used to treat these fish. When you eat farmed salmon, you get dosed with the same drugs and chemicals. The solution: Switch to wild-caught Alaska salmon. If the package says fresh Atlantic, it’s farmed. There are no commercial fisheries left for wild Atlantic salmon. Farmed Fish vs. Wild Fish: How Healthy Is The Fish At Your Favorite Grocery? 6. The Cancer Researcher Won’t Drink: Milk Produced With Artificial Hormones Rick North is project director of the Campaign for Safe Food at the Oregon Physicians for Social Responsibility and former CEO of the Oregon division of the American Cancer Society. The problem: Milk producers treat their dairy cattle with recombinant bovine growth hormone (rBGH or rBST, as it is also known) to boost milk production. But rBGH also increases udder infections and even pus in the milk. It also leads to higher levels of a hormone called insulin-like growth factor in milk. In people, high levels of IGF-1 may contribute to breast, prostate, and colon cancers. â€Å"When the government approved rBGH, it was thought that IGF-1 from milk would be broken down in the human digestive tract,† says North. â€Å"There’s not 100 percent proof that this is increasing cancer in humans,† admits North. â€Å"However, it’s banned in most industrialized countries. † The solution: Buy raw milk or check labels for rBGH-free, rBST-free, produced without artificial hormones, or organic milk. These phrases indicate rBGH-free products. Why Do Humans Still Drink Milk? 7. The Biotech Specialist Who Won’t Eat Conventional Soy: GMO Unfermented Soy Michael Harris is biotech specialist who has directed several projects within the biotech sector including those for genetically engineered food. He has been a consultant, manager and director for companies such as Xenon Pharmaceuticals and Genon Corporation. The problem: Genetically engineered food is a cause of great concern due to the manipulation of DNA and genetic code including transfers from one species to another. Fermented Soy Is The Only Soy Food Fit for Human Consumption and since almost 90% of soy in the world is genetically modified, if you are not ensuring sources are organic, long-term health problems are inevitable, especially since soy has been found to affect hormonal balance and even cause cancer. The solution: Check labels to ensure soy is Non-GMO or organic and never consume unfermented sources. If possible contact the company to find out exactly where the Non-GMO soy was obtained. 8. The Organic-Foods Expert Won’t Eat: Conventional Apples Mark Kastel, a former executive for agribusiness, is codirector of the Cornucopia Institute, a farm-policy research group that supports organic foods. The problem: If fall fruits held a â€Å"most doused in pesticides contest,† apples would win. Why? They are individually grafted (descended from a single tree) so that each variety maintains its distinctive flavor. As such, apples don’t develop resistance to pests and are sprayed frequently. The industry maintains that these residues are not harmful. But Kastel counters that it’s just common sense to minimize exposure by avoiding the most doused produce, like apples. â€Å"Farm workers have higher rates of many cancers,† he says. And increasing numbers of studies are starting to link a higher body burden of pesticides (from all sources) with Parkinson’s disease. The solution:Buy organic apples or apples from a farmer that you trust!

Hume and Matters of Fact Essay

According to Hume, there are two types of beliefs, relations of ideas and matters of facts. Relations of ideas are indisputable. Such as a widow is a woman whose husband died. Such thoughts are usually definitions. Since it is impossible for a Widow to be anything other then the definition, these ideas are indisputable. Matters of facts claim that if the opposite is imaginable, then it is possible. Matters of fact are debatable, such as the belief in a God or that the world will end. While it is true that these abstract ideas are easily debatable, other ideas that we held as true are also only matters of fact, such as putting wood in a fire will make I burn. While we hold that it is true that everything falls towards the earth, and that the sun rises, it is possible that the sun will not rise and that things will not fall towards the earth, these beliefs are matters of fact because we can visualize the opposite occurring Hume denies reason any power because he is an empiricist. Instead three main principles exist that help humans form ideas; they are resemblance (when looking at a picture a person thinks of the object), contiguity (thinking of an object that is close spatially), and cause and effect (association). Hume claims that reason alone cannot establish matters of facts. There is no reason to believe that what happened one time will happen again. For example, there is no reason for Adam to believe that a rock will fall if he drops it unless he experiences it many times. Even with experience one cannot reason a matter of fact to be true, because the universe may not be uniform. There is a chance that because one thing happened many times, it makes it more possible that it will not happen again. Hume gives a very possible argument for why the universe may not be uniform. He claims that all beliefs are either arguments based on relation of ideas (such as definitions) or arguments based on experience (such as matters of fact). All arguments based on experience require a uniformity of nature principle. In order to argue that putting wood in a fire makes it burn, someone must do the same action many times, but even then there is no reason to believe that the wood will not burn, but extinguish the fire instead. There is a chance that wood actually extinguishes fires, but once in a while it will just burn instead. Unless nature is uniformed then there would be no reason for anyone to believe that wood will burn. The uniformity of nature cannot be proved or based on experience. If based on experience, a circular argument is formed. Therefore there are no reasons for believing that nature is uniform. Therefore no arguments based on experience are reasonable.

Essay on RE DO

Essay on RE DO Essay on RE DO Ivon Dimas Second Draft May 11, 2015 Re-Do Introduction Robert Dahl, a leading democratic theorist, once said: â€Å"Every member must have an equal and effective opportunity to vote, and all votes must be counted as equal†. Every four years in the month of November, citizens of America go to the polls to vote for the President and Vice President of the United States. Throughout the election, we are guaranteed one vote per person and equal voice in electing the people to serve in our government. The way the United States votes its president into office is through the Electoral College. The Electoral College is a body of people, theoretically representing the fifty states of America, who cast votes for the election of the president and vice president. Should the Electoral College be abolished? Yes, the Electoral College should be abolished for three reasons: it allows the election of a president who may not have the support of a majority of voters, gives preference to larger states, and does not give every voter an e qual voice. Definition of terms Abolished: to do away with; put an end to; annul; make void Candidate: person who seeks elected office. Congress: legislative branch of the government, responsible for making laws. The U.S. Congress has two bodies, the House of Representatives and the Senate. Election: the selection of a person or persons for office by vote. Electoral College: a body of electors chosen by the voters in each state to elect the president and vice president of the U.S. Electoral Vote: the vote cast in the electoral college of the U.S. by the representatives of each state in a presidential election. Federal government: pertaining to or of the nature of a union of states under a central government distinct from the individual governments of the separate states National Popular Vote Interstate Compact: is an agreement among several U.S. states plus the District of Columbia to allocate their presidential electors to the winner of the national popular vote under certain conditions Popular Vote: the vote for a U.S. presidential candidate made by the qualified voters, as opposed to that made by the Electoral College. Representative: a person who represents a constituency or community in a legislative body, especially a member of the U.S. House of Representatives or a lower house in certain state legislatures. Senator: a member of a senate. Winner take all: a situation or outcome wherebythe winner receives all the prizes or rewards History In 1786, the United States gained its Independence from the United Kingdom (Holcombe). This left the new-found states with a large debt to France. The governing body that led the country through the American Revolution was the Continental Congress. This body created the Articles of Confederation after the war. The articles served as the federal body, but had limited powers. One such power that they lacked was the power to tax. The articles also upheld state government over federal government. This made it increasingly hard for the young country to pay back its debt and remain united (History). In 1787, the federalists, under the leadership of Alexander Hamilton, drafted the Virgina plan to solve this problem (Smith). The plan was constructed under the idea of having a centralized federal government. Paying back France was just a noble cause. The Virginia plan proposed the two branches of legislation we know as the Senate and the House of Representatives. The House would be proportioned by population, and each state would have two representatives in the senate. The anti-federalists, proposed that such an act would destroy the newly established state governments (Holcombe). The smaller states came together and drafted a counter-plan known as the New Jersey Plan. This plan would continue to limit the power of a centralized federal government, and it would introduce no new congress (Holcombe). The latter part of their plan was put in to assure that the smaller states

Chem Paper essays

Chem Paper essays When people think of hydrogen, outside the studying of a chemistry class or something to that effect, thinks immediately of the hydrogen bomb. This situation is obvious a big image problem. Thanks to new technology, hydrogen has escaped the imagine of the unbearable to other more economical thoughts. The Bush administration as well as environmentalist, are working side by side to look at hydrogen as a power, to power emission-free fuel cells, said by a recent Natural Resources Defense Council report, which will secure a safer and cleaner future for the world. Having a lot of use to it, a fuel cell is essentially a huge battery which places hydrogen through chemical reactions to create electrical energy. What can this do for us? Well, using this method could result in a world which cars run or highly efficient engines of a cost of a penny a mile, which is currently half the rate of modern cars. In the mean time releasing nothing more harmful than water, which we need to stop a big part of air pollution. With all this factors in consideration hydrogen should, and will be the next big thing. This wasnt the first time, in the U.S., that we tried to use alternate fuels. The other alternatives that we tried out as energy efforts are synthetic fossil fuels or fusion power. Unfortunately neither where efficient enough for use, at least not yet. Despite the pit stops, in technology, researchers are still looking for efficient fuel-cell technology which uses hydrogen to power automobiles without creating pollution. While releasing pure water vapor as the exhaust, fuel cells are considerably like hydrogen powered batteries, squeezing electricity out of the reaction between the gas and oxygen that makes water. Despite the fact that it would be better for us to get ride of the common use of oil use, it is cheaper for coal and oil use, and much more expensive for the use of fuel cells. ...

Organic Thin Film Transistor - Research Paper Example The top diagram (a) shows a top contact device in which the two (source and drain) electrodes are evaporated onto the semiconducting layer by applying a mask and the bottom diagram (b) shows a bottom contact device in which the semiconductor is deposited onto the gate insulator with prefabricated electrodes. Studies on organic semiconductors began in the 1940s and these components were mostly used in xerography due to their photoconductive properties. They have only gained more widespread attention in recent years due to impressive performance and efficiency improvements making it possible for a wider range of further applications. In particular, the considerable improvements in OTFTs have led to an enhanced understanding of their conduction mechanisms and performance characteristics, and fabrication technologies have been developed for optimising their morphology and structural order2. It should also be noted however, that despite the advancement in OTFTs and increasing uses for them, they are still not able to replace the more common inorganic based TFTs for certain applications in which faster switching speeds are required. This is due to their still relatively low mobility, despite considerable improvement in this regard, as shown in the chart below3. On the other hand, OTFTs are better suited where large area coverage is required and they offer compelling advantages of low cost, low temperature processing and structural flexibility. This makes them especially useful for switching in active matrix flat panel displays that consist of liquid crystal pixels or organic LEDs, for radio frequency identification tags (RFIDs), etc. As with inorganic semiconductors, organic semiconductors are also directly affected by such features as purity, crystallinity, molecular packing and growth mode4. The microstructure and morphology of all transistor devices are therefore important because they determine their electrical

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

School and Sociaty - Research Paper Example Mann is known as â€Å"father of American common school† Talented and hard working teachers can mould a weak student into a strong one. There should be similarity in text books and criterion is set to select teachers. Teachers be paid good amount as salary to motivate them and make job respectable. Tozer states that â€Å"schools are complex institutions with diverse and complicated relationships to the communities in their surroundings†. Now teachers are supposed to understand the link of education with society and should set goals accordingly. Now political economy is term which comprises of political, cultural, social and economical aspects of society. In the same way ideology covers the beliefs and ideas of a society. Therefore these are not separate terms and must be studied in relation to each other. (Tozer, Violas & Senese, 2001) Now if I apply all these terms on my education then my education did not commensurate to my future social and economic challenges. When I went to college, than I realized that school education was just useless for me as I was unable to perform well. I was weak in mathematics therefore I was unable to perform well as a cashier in a grocery shop. Here comes the fault of my school system. Schools of Bronx New York were overcrowded. Teachers were under educated and were low paid. Teachers were also not made accountable by the government authorities for imparting poor education. This weak foundation grew with me and I faced lot of problems in higher education and in job as well. Thomas Jefferson says that citizens should be educated in way that they can liberally understand the world and should also know the functioning of society. Local schools system of a society should be able to run and mange school in a great fashion. Jefferson emphasized on training of mental abilities in his educational ideal. He gave the idea of autonomy to every diverse school district. Primary schools education should be developed in such a wa y that in future the students can ensure the existence of society. Jefferson’s ideal has not played any part in my education. After my basic education I was unacceptable to the society because of poor educational background. Jefferson wants to see an educational system that can strengthen all dimensions of society including economy. After completing basic education I was unable to handle minor accounts efficiently. Initially I was taken as thief in grocery shop because of cash shortage on daily basis but ultimately I was fired. Jefferson wanted students to understand all dimensions of society including ideology and demography. When appeared in entrance exam for admission in a college, I could not understand any thing in the paper and got failed. I did not know the basics of English, Mathematics and history (Gramsci, 2009) Now the schools are accessible to every child but previously the distance to schools was the de motivating factor for students. I will highlight the quality of teachers here as I suffered a lot from this aspect in my life. It is the teacher who can shape the life of his students for making them important part of the society. My teachers were not highly educated as I was studying in a normal public school. Jefferson and Mann always emphasized on highly qualified and enlightened teachers. When I appeared for entrance exam I was unable to understand any thing. I did not know basics about Mathematics and English. I was also fired
