Working Towards Your Dream Job - 853 Words
Working Towards Your Dream Job At some point in our lives, the majority of us will find ourselves searching for a job. From deciding what position you want, to following up after an interview, you must be intentional about your decisions throughout the job search process. Figuring out the job you actually want might be the toughest and most important part of this. If you are working on a degree or certification for a specific career, my advice is to search for an entry level position with a company that you will be able to use your degree/certification in one day. Even if filing documents or sweeping a warehouse isnââ¬â¢t your dream job, doing these tasks at your dream company is one of the best ways to realize your long-term goal. This will not only be beneficial to you, as you will be getting firsthand experience with the company to see if it is a place you really want to work for, but the hiring manager for the entry level position could see you as a long term investment, w hich will give you a leg up on the competition. Also, most companies prefer to promote within the organization, so once you complete your degree and a position is open, you will have that extra boost in your favor. Once you decide what job youââ¬â¢re after, you need to prepare your resume. The resume should be clean, simple, and no more than two pages. Keep it updated with any major accomplishments, but other than that, leave it alone. Send your resume only when you know that the company is hiring forShow MoreRelatedWhat Makes A Dream Job?1355 Words à |à 6 Pagessure what your dream job is? Want help figuring it out?

Etiology, Behavioral Aspects, and Educational Implications of Emotional Behavioral Disorders Emotional Behavioral Disorder (EBD) also known as (Behavioral Disordered, Seriously Emotionally Disorders, and Emotional behavioral Disorders) is the 4th largest disability category under the Individuals with Disabilities Education Act. EBD like most disabilities has some sort of vagueness to its definition. The Individuals with Disabilities Education Act of 1997 (IDEA) defines EBD as a condition exhibiting one or more of the following five characteristics: An inability to learn that cannot be explained by intellectual, sensory, or health factors, An inability to build or maintain satisfactory interpersonal relationships with peers and teachers, Inappropriate types of behavior or feelings under normal circumstances, A general pervasive mood of unhappiness or depression, and A tendency to develop physical symptoms or fears associated with personal or school problems (Sec. 300.8 Child with a disability., 2004). According to IDEA the in order to be classified as EBD one has to exhibit one or more of these characters tis over a long period of time and to a marked degree that adversely affects a childââ¬â¢s educational performance (Sec. 300.8 Child with a disability., 2004).

Persuasive Speech Outline Music Downloading Essay This relation is what makes music as popular as it is. Needless to say, music is, in a way, a life necessity. Why should people have to pay for a life necessity? L. Music is constantly surrounding us. A. It is the radio, b. Behind every movie, television and commercial. It is playing in stores and in restaurants, d. Either conscience or unconsciously, 98 % of people have a song playing back in their minds according to an article study in the New York Times Magazine. II. The progressions of distributing music. E. Thomas Edison can be the one to thank in order for making it possible to distribute music around the world for millions of listeners. I. He invented the phonograph in 1877 which was one of the first ways of distributing sound Listeners today now have their music stored on the computer, where each individual song is a file.

G. The ARIA and record companies claim that downloading music is an infringement to intellectual property and deprives artists of their rightful share. It. Arguing that that files downloaded are the work of the artist who made them, not public property. IV. Not all artists feel this way, however. H. Wired News interviewed front man Jeff Tweedy of the band Wilcox in November of 2004. Who disagrees with these claims completely. I. A piece of art is not a loaf of bread. When someone steals a loaf of bread from the store, thats it. The loaf of bread is gone.

How the perceive your work, changes your work V. Theft and Lost Sales: When music files are shared the artists or copyright owners do not receive any compensation. Therefore, they believe sharing and copying files is stealing in the same way that shoplifting is. J. As if only downloading could somehow have been prevented, would it put stunning amounts of money into impoverished artists hands? K. This statement leaves room to wonder. Why does the music industry persist in saying that every download is a lost sale? Because it cannot possibly be true. People, even downloaded, only have a finite amount of money. At times, sure they would have purchased a CD album but if stopped from downloading, would they troop our to the shops to buy these songs. L. Treating your audience like thieves is absurd. Anyone who chooses to listen to music becomes a collaborator. VI. Harvard Business School Professor Felix Borehole-Gee fount through their research that most music downloading is done over Peer to Peer networks m. Mostly used by teenagers, and college kids. Groups that are Money-poor but Time-Rich. Meaning that they wouldnt have bought the songs they downloaded. v. V. In that sense, the music industry cannot claim those downloads as lost record sales No, downloaded are not spending money on the music industry but the true volume of lost sales is nowhere near the claims made. VI. Illegal downloading may help the industry slightly with another major segment. Not only is there a significant less amount of sales that generally assumed, but also with the ability to download music off the Internet, Samplers are created. O. This in turn generates a new fan base. Samplers are a crowd who downloads a song or two and then, if they like what they hear go out and buy the music. P. Other research shows that people do not download entire CDC. They download a few songs, typically the hits that would also appear on a Top 40 station. V. This suggests that peer-to-peer is much like the radio, a great tool to promote new music. Also being less costly to artists than the dado itself.

US Airlines Essays - Air Traffic Control, , Term Papers
US Airlines Deregulation of the U.S. airline industry has resulted in ticket prices dropping by a third, on an inflation-adjusted basis. As a result some 1.6 million people fly on 4,000 aircraft every day. Airlines carried 643 million passengers in 1998, a 25% increase over 1993 and the FAA estimates that the nations airline system will have to accommodate 917 million passengers by the year 2008. The growth in air travel threatens to overwhelm the presently inadequate air traffic control system, which has not kept pace with available technology in navigation, communications, and flight surveillance. Much of the equipment used for air traffic control today is based on fifty-year-old technology; for example, analog simplex voice links for communications and ground-based radar for surveillance, and VHF Omnidirectional Range/Distance Measuring Equipment (VOR/DME) for navigation. The lack of system automation imposes heavy workloads on human air traffic controllers and increases the risk of accidents in heavy traffic situations. Capacity limits are being reached in both airports and airspace, with congestion delays in departure and arrival schedules reaching record numbers. Funds to upgrade the air traffic control system are available in the trust fund created to receive the tax applied to airline passenger tickets and the tax on fuel for general aviation. The General Accounting Office says modernizing the air traffic control system will cost at least 17 billion for just the first 5 years of the FAAs 15-year National Airspace System improvement plan. It is the NAS that provides the services and infrastructure for air transportation. Air transportation represents 6% of the Nations gross domestic product, so the NAS is a critical element of our national economy. Given the size of the NAS, the task ahead is enormous. Our NAS includes more than 18,300 airports, 21 air route traffic control centers, over 460 air traffic control towers and 75 flight service stations, and approximately 4,500 air navigation facilities. The NAS spans the country, extends into the oceans, and interfaces with neighboring air traffic control systems for international flights. The NAS relies on approximately 30,000 FAA employees to provide air traffic control, flight service, security, and field maintenance services. More than 616,000 active pilots operating over 280,000 commercial, regional, general aviation and military aircraft use the NAS. On March 11, 1999, the FAA released the NAS Architecture Version 4.0 to the public. Key influences on the architecture include the 1996 White House Commission on Aviation Safety and Security, which recommended that the FAA accelerate modernization of the NAS, and the 1997 National Civil Aviation Review Commission, which recommended funding and performance management methods for implementing NAS modernization. It describes the agencys modernization strategy from 1998 through 2015. Based on the Free Flight operational concept, Version 4.0 contains capabilities, technologies, and systems to enhance the safety of the aviation system and provide users and service providers with more efficient services. Free Flight centers on allowing pilots, whenever practical, to choose the optimum flight profile. This concept of operations is expected to decrease user costs, improve airspace flexibility, and remove flight restrictions. The NAS Architecture is divided into three modernization phases and its implementation is being synchronized with the International Civil Aviation Organization to ensure interoperability and global integration. ?h Phase 1 (1998-2002) focuses on sustaining essential air traffic control services and delivering early user benefits. Free Flight Phase 1 will be implemented. Controller computer workstations will begin major upgrades. Satellite-based navigation systems will be deployed, and air-to-air surveillance will be introduced. The Year 2000 computer problem will hopefully be fixed. ?h Phase 2 (2003-2007) concentrates on deploying the next generation of communications, navigation and surveillance (CNS) equipment and the automation upgrades necessary to accommodate new CNS capabilities. Satellite-based navigation systems will be further augmented in local areas for more precise approaches. New digital radios that maximize the spectrum channels will be installed. As users equip, automatic dependent surveillance ground equipment will be installed to extend air traffic control surveillance services to non-radar areas. Tools from Phase 1 will be deployed throughout the NAS and upgraded as necessary. ?h Phase 3 (2008-2015) completes the required infrastructure and integration of automation advancements with the new CNS technologies, enabling additional Free Flight capabilities throughout the NAS. Two important features will be NAS-wide information sharing among users and service providers and four-dimensional flight profiles that utilize longitudinal and lateral positions and trajectories as a function of time. The goals for modernizing the NAS are based on improving: ?h Safety ?V such as better weather information in the cockpit and on controller displays. ?h Accessibility ?V such as instrument approaches to many more airports. ?h Flexibility ?V such as allowing

Osmosis Essay Essay Example
Osmosis Essay Paper Osmosis is a form of passive transport, and a specialised form of diffusion. It is the movement of water from a dilute solution to a more concentrated one, through a semipermeable membrane. Hence it is where water moves from a high to a low concentration. I will design an experiment to test this process on a typical example of osmosis effect on plant cells, taking as the sample, potato. It is through osmosis and the fluctuating levels of water in the cell that the concentrations of minerals in the plant are regulated. Expt. 1 Last year, I conducted two experiments in which dialysis tubing was used to simulate the semipermeable membrane. In the first experiment a knot was tied in one end of a length of soaked dialysis tubing and a pipette was used to half fill it with a strong glucose solution. The air bubbles were expelled and a knot was tied in the other end. At this point the tubing was flaccid (limp). When it was then placed in a test-tube full of distilled water, it became turgid (firm). [See diag.1] Expt. 2 In the second experiment red-dyed sugar solution was placed in a bell-shaped piece of apparatus, with a capillary tube off it and a cellulose film over the bottom [See diag.2]. This was then placed in a beaker full of distilled water and left for half an hour, by which time the level of water in the beaker had gone down, and red dye had moved up the capillary tube. The water in the beaker had not turned red. The experiment was then repeated with a stronger solution. The volume of water in the beaker decreased further; the dye went further up the capillary tube.

This is why the water in the beaker did not turn red, while the red dye in the capillary tube did become paler. The second experiment also showed that the more concentrated the solution, the more water diffused in by osmosis. Expt. 3 More recently, I conducted an experiment investigating these processes in a real plant cell. An onion was cut up, and two small pieces of the epidermis (a single layer of cells) were peeled, cut and placed onto microscope slide. Onto one of them was pipetted a few drops of distilled water; onto the other was pipetted a few drops of 1 molar glucose solution. Cover slips were then placed onto the two pieces of onion epidermis. [see diag.3a]. These were then placed under the microscope, and their cells looked identical [see diag.3b]. Fifteen minutes later, however, a marked change had been observed. While the onion cells bathed in distilled water had become turgid [see diag.3c], those bathed in glucose had been plasmolysed [see diag.3d]. Plasmolysis occurs when water diffuses out of the cell vacuole, causing the cytoplasm to have a decreased volume, in turn causing the cell membrane to pull away from the cell wall. It only occurs when the cell is hypoosmotic relative to the bathing solution. That is to say that plasmolysis only occurs when the cells solute potential (?s) is lower and therefore water potential (?w) is higher than that of the bathing solution. The bathing solution is hypertonic: this means that there is a higher concentration of solute, and thus lower concentration of water, in the bathing solution than the cell. Totally dilute water has infinite water potential, and zero solute potential. In Expt.3, the water potential of the onion cells in the glucose solution was greater than that of the onion cells in the distilled water. So, because the onion cells in the glucose solution were hypoosmotic, they were plasmolysed. Whereas the onion cells in the distilled water were hyperosmotic (had higher solute, and therefore lower water, potential), so became turgid. In my investigation of osmosis in potato cells, I hope to be able to determine the water potential of the cells. I will do this by finding the isotonic (equal solute, and therefore water potential) bathing solution. Key Variables I will be testing a total of 5 bathing solutions (0.2, 0.4, 0.6, 0.8 mol glucose solutions distilled water). I will require 10 potato pieces (two for each solution). As they will be cut from a slice of potato 1 cm tall, the height is already constant. I must also ensure that the breadth of each piece is constant: 1cm. It is vital that the breadth and height are constant so that it is possible to measure any change in length. Of course, in order to measure the change, it will be necessary to ensure that the initial lengths are constant, and to ensure that I measure the same sides at the beginning as the end. To do this, I will take a tiny segment out of one side (I will measure the other). The initial lengths will be 2.5 cm. Obviously, it is hoped that the potato will have an even density, but in case it does not, the individual masses will be measured beforehand as well as afterwards. Through the use of such a precise piece of apparatus, I hope to be more accurate in my final readings. Also, this way the comparison between increase/ decrease in the lengths of potato pieces may be reinforced by a comparison between the increase/ decrease in their masses. So the readings will not only be more accurate, but also more reliable. The initial volumes of the bathing solutions must be constant, in order to better compare any changes in volumes. The initial volumes will be 20ml. The amount of time during which the potato pieces are left in their bathing solutions must be constant. The time set will be 30 minutes. The only variable left is the strength of the bathing solution. These are: 0.2, 0.4, 0.6, 0.8 mol glucose solutions distilled water. I am using these solutions because I want to show some potato cells become turgid and be plasmolysed: and I will need this sort of range to do so, because potato has a lower water potential than onion (and will therefore need a stronger solution than that used in Expt.3). Aim To discover the water potential of the average potato cell in terms of the relative isotonic bathing solution. Hypothesis As demonstrated in the three experiments in the Introduction, osmosis determines that water travels from high to low concentration over a selectively permeable membrane. In the planned experiment, when the bathing solution is hypertonic (lower water potential, higher solute potential) relative to the potato cell, water will flow out of the vacuole into the bathing solution (plasmolysis, Expt.3). This will cause the potato cells to become flaccid, shrinking and losing weight. The potato pieces that lose mass, and decrease in length will be the ones with high water potential, relative to the bathing solution. I think this will happen in the distilled water, because completely distilled water has infinite water potential. When the bathing solution is hypotonic (higher water potential, lower solute potential) relative to the potato cell, the cell will become turgid because water will flow from the bathing solution into the vacuole. The potato pieces that increase in length and gain mass will be the ones with low water potential, relative to the bathing solution. I predict this for the strong glucose solutions (0.4, 0.6, 0.8 mol), because I have seen from experiments 12 that strong glucose solutions have low water potential. When the bathing solution is isotonic (equal water potential, equal solute potential) relative to the potato cell, the cell will not change. The potato pieces that neither increase nor decrease in length and neither lose nor gain mass will be the ones with the same water potential, relative to the bathing solution. I believe this will occur in the weakest glucose solution (0.2mol) because, although a 0.1mol solution plasmolysed the onions in Expt.3, potatoes have a lower water content than onions (85% as opposed to 89%), meaning that they will also have a lower water potential. I am therefore predicting that the water potential of the average potato cell is equal to that of a low strength glucose solution. I say this because I know that, in distilled water, the cells become turgid; and in strong glucose solutions, the cells plasmolyse. Apparatus slab of potato 1cm thick, scalpel, white tile, solutions (0.3, 0.6, 0.9 mol glucose), distilled water, 5 boiling tubes, clock, ruler (mm), electric balance (to 0.01g), and a measuring cylinder, forceps, boiling tube rack, paper towels. Planned Method First I will cut out the 10 potato pieces (10x10x25mm) on the white tile with the scalpel, taking a chunk out of one side [see diag. 4a]. Then I will measure their masses on the electric balance. Then I will measure out the volumes of the bathing solutions (20ml each) in a measuring cylinder (the measuring cylinder will be dried after each measure) [see diag. 4b]. Then I will pour the bathing solutions into the 5 boiling tubes, which I will have labelled, and two potato pieces will be placed into each boiling tube and the timer started [see diag. 4c]. 30 minutes later, I will remove the 10 potato pieces, rinse (briefly) and dry them, and measure their lengths and masses. These will then be recorded. Then the volumes of the bathing solutions will be recorded (again, the measuring cylinder will be dried after each measure). Diagrams Safety Precautions As with all substances in a science laboratory, it is vital that I do not taste the potato, the solutions or the distilled water. I must not touch my face or licking my fingers before washing my hands, but I should attempt to avoid getting the liquids if possible, as it risks contaminating our results. Evidently, care must also be taken with the scalpel in the cutting of the potato, as it is a sharp instrument.

They shop for their own trendy clothes because it is getting increasingly important to wear the latest fashion. Furthermore, there is a growing number of younger and younger children colouring their hair, often with the permission of their parents. The question, which arises from this, is: Why do adolescents pay more attention to their appearance than in past years? The answer is difficult to find because it is complicated to reveal psychological motivations. Nevertheless, considering the extraordinarily high importance of means of mass communication like TV and Radio, the influence of the media on young people is, without doubt, immense. Moreover, it is probable that the commercials of big companies with a widespread reputation are, in some way, responsible for the above-mentioned movement.

They shop for their own trendy clothes because it is getting increasingly important to wear the latest fashion. Furthermore, there is a growing number of younger and younger children colouring their hair, often with the permission of their parents. The question, which arises from this, is: Why do adolescents pay more attention to their appearance than in past years? The answer is difficult to find because it is complicated to reveal psychological motivations. Nevertheless, considering the extraordinarily high importance of means of mass communication like TV and Radio, the influence of the media on young people is, without doubt, immense. Moreover, it is probable that the commercials of big companies with a widespread reputation are, in some way, responsible for the above-mentioned movement. That is why more and more firms in the clothing industry as well as those concentrated on the marketing of beaut y products start developing strategies to take advantage of this efficient way of influencing a broad part of the population in order to attract the younger target group.

Evidence vs. Dogma Essay Example | Topics and Well Written Essays - 750 words
Evidence vs. Dogma - Essay Example They continue to advocate the Biblical version of events, that an alien being of undetermined construction and origin made not only the earth and everything on it but the entire universe too. Eventually, society will universally embrace evolution as a fact but, as life itself does, society evolves slowly. People who, despite all evidence to the contrary, continue to ââ¬Å"believeâ⬠that the God, as described in the Bible, Koran and/or Torah, created everything in the universe are described as ââ¬Å"creationistsâ⬠, and the pseudo science they ascribe to is called ââ¬Å"creationism.â⬠Creationism attempts to offer evidence to support superstitious beliefs by challenging the scientific theory. Creationists claim that evolution has not been conclusively proven, that itââ¬â¢s just ââ¬Å"a theory.â⬠Creationists require a higher standard of verification from scientists than they are willing to offer for creation. Scientists are asked to satisfy all questions, whe ther realistic or not, pertaining to the origin of life. Itââ¬â¢s an impossible task to answer with certainty the question ââ¬Å"how we got hereâ⬠unless one accepts the Biblical version of events which is all the evidence they need. ... No one has ever actually seen an atom. No one has ever directly observed either electricity or gravity. To even suggest that science cannot deal with unobservable is to display an ignorance of the nature of the scientific enterpriseâ⬠(Albert, 1986). Scientists can track the ancestry of living things by comparing similar traits and gene mapping techniques. Evolutionists utilize this scientifically sound method, and it has been conclusively demonstrated that humanââ¬â¢s nearest relatives are chimpanzees. Genetically speaking, in addition to physically observable similarities, activities such as tool making and similar social structures, the different types of primates, chimps and people are very similar, too much so for it to be just a coincidence. ââ¬Å"Biologists can cite many instances of parallel evolution in which forms that are only distantly related have developed similarities in structureââ¬âfor example, the almost identical structures of human and octopus eyes.â ⬠(Albert, 1986). Darwin theorized that animals physically acclimate to a new surrounding over millions of years, a process which he called natural selection. Since Darwinââ¬â¢s lifetime, scientists have also been pointing to mutation as a method of evolution that can be employed in conjunction with Darwinââ¬â¢s theory. On his historic journey to the Galapagos Islands located about 600 miles off the western South American coast, Darwin carefully documented tangible verification for his evolutionary theory. There are 13 islands of the Galapagos chain, all located relatively together, yet they are greatly different geographically, some had tropical-like conditions, others resembled a desert, some rocky, some sandy, for example. Darwin observed clear physical
