Respiration

Respiration RespirationRespiration is a physical process in which living organisms take in oxygen from the surrounding medium and emit carbon dioxide. the term respiration is also used to refer to the liberation of energy, within a cell. from fuel molecules such as carbohydrates and fats. Carbon dioxide and water are the products of this process, which is sometimes called cellular respiration to distinguish it from the physical process of breathing.Small organisms of the kingdoms Protista and Prokaryotae have no specialized respiratory mechanisms; instead, they rely on the diffusion of oxygen and carbon dioxide across a cell membrane. The concentration of oxygen in the organism is less than that of the surrounding air or water, and the concentration of carbon dioxide is greater. As a result, oxygen diffuses into the organism, and carbon dioxide diffuses out.In aquatic lower animals that are more complex than sponges, a circulating medium carries the respiratory gases from outer tissues to cells that are distant from the sight of gas exchange.Anatomy of the lungs and heartThese animals have gills, which auxiliary respiratory mechanisms keep a constant current of fresh water flowing. The gases are diffused through the epithelium of the gill, and the extended surface, produced by the branching of the gills, enables large quantities of blood to be oxygenated in a short time.The respiratory and circulatory systems of air breathing animals have become adapted and modified for life in oxygen deficient environments. For example, people living in higher altitudes would have larger lungs than people living at lower altitudes. Humans respire through their lungs, as do most mammals and reptiles. Within the thorax, the lungs are held close to the body wall by atmospheric pressure. When the thorax expands, the lungs fill with air drawn through the upper respiratory passages.

Computer - Coursework Example The digital computer operations are done by logic circuits that are digital circuits. The outputs of such circuits can be regulated by the input conditions. The many processing data within the interior of the computer ought to work in a synchronized way. This is often achieved by regulating them with a steady oscillator that always acts as the oscillator. The CPU is the main storage unit of the computer and sometimes can be referred to as the computer’s memory. Initially, it consisted of vacuum tubes, but later consisted of ferromagnetic cores with doughnut shapes. Data and programs are not always used in the main storage and can always be stored in secondary or auxiliary storage. While punched paper cards have this function, the main materials that are currently in use include flash disks, magnetic tape and flash memories. When compared to the RAM, these are quite cheap. Today, magnetic tape is used mainly for the storage of voluminous data or main backups. In optical and magnetic systems, the norm is similar. The disk drive also has a motor that can spin the optical head. The drives are designed in a number of forms (Knuth, 2003, p.69).  The flash disks have nonvolatile memory, which can be reprogrammed or erased. The central processing Unit (CPU): The circuitry and the motherboard must be powered. The CPU acts as the thinking process or the computer brains just like humans have their brains to process and relay information. The processors usually have a cooling unit that helps in reducing the heat within the computer. The computer usually gives its user all the necessary instructions during operation. The common processors have quad-cores (Knuth, 2003, p.76).  The modern computers have at least two CPUs, which help in the power of processing and to optimize the potential. The power supply: Just like humans need the energy to operate, the computers also need the power to operate. The energy

Working Capital Simulation Essay Example for Free

Working Capital Simulation Essay This simulation has given me a better understanding of what managers and CEO’s go through when making decisions for the company. As I went through each simulation more than once to see what affects the decisions had on cash flows, sales and EBIT. In some situations they changed whether it dropped or risen, and others they were completely stagnant with their movement through each phase. Below I will point out how and why I made each decision. Phase 1, I chose to acquire a new customer and tighten up accounts receivable in both times I did the simulation. I chose to take on a new customer because SNC needed the exposure to become known as it is starting to get widespread exposure. The results of this acquisition were that it increased the sales significantly but also left us with higher receivable an inventory balances. (Harvard SNC Synopsis) The results of tightening up the accounts receivable were that sales have declined but the receivables improved which freed up cash. (Harvard SNC Synopsis) In phase 2, I chose to expand the online presence as well as develop a private label in one simulation and the second simulation I just chose to expand on line. In my first choice since I chose to expand online and develop the label, the amounts varied in increase of cash flows. The expansion of the online presence increased Internet sales and the private label increased the EBIT margin only a little. This also counteracts with the accounts receivable and inventory balances after phase one. But it was not that drastic of a change. In ’17 there was no increase or decrease in cash flows, which only means that in that year we broke even on the developing label side. The last phase, I chose to adopt a global expansion strategy in one trial and in the second I chose to adopt and acquire the high-risk customer. The results of acquiring a high-risk customer increase the sale, but had a dramatic affect on the receivables. SNC has now to consider witting off a portion of the outstanding balance as the company Midwest Miracles filed for chapter 11 bankruptcies. This simulation alone has taught me one of the many risks of doing business with any company. (Harvard SNC Synopsis) I thought that after acquiring the company, they could maybe stand on their own with the help of SNC and pull out of their financial hardship. It had the complete opposite affect on the SNC and it could have potentially ruined my company, as well as made me lose investors. The global expansion however helped the SNC grow its top of the line with the new customer Viva Familia. Like expanding online, the global strategy was another attempt to make sure SNC is the first company consu mers think about when dietary supplements. Limiting access to financing can hinder any company or person from trying to grow their business. It can cause higher interest rates on loans and credit fees as well as force businesses to face hardships when it comes to registration costs, policies and equipment needed for the business. (Parrino, Kidwell, $ Bates, 2012) It can also limit the profits they may encounter with consumers on in the new market. The limit of access to finances also hinders the process to develop and own their own brand of products. Making a if I were really the CEO of SNC or any business, I would need the help of a team to help make these decisions on and expansion and growth as well as investing in other companies. This simulation put in perspective the skill set and education needed after studying finances to even hope that you can make a profit on any decision made. It is a really difficult task to try and manage a company as well as keep up with the market. If this were a sole proprietorship, it would really be stressful to handle all by their lonesome.

Understanding Alcohol :: Drugs and Alcohol, Addiction, Intoxication

Alcohol is not only the reason why prohibition took place in the 1920s, but it is also the reason why many persons wake up not remembering their previous night’s endeavors. It has always been evident that alcohol has an effect on brain function, which in-turn impairs the behavior of a person. Alcohol can be separated into two separate groups: what is expected to happen, and what actually happens. Alcohol is expected to play social lubricant and aphrodisiac. When it comes to being social alcohol does seem to have a loosening effect on people, however, it is almost the opposite sexually. Alcohol actually acts as more of a suppressant when sex is brought into the picture. It has only be known to be a sort of aphrodisiac because that is the way it is perceived and that is the way in which people choose to perceive it. Given the choice between two women, one holding an alcoholic drink and the other not, a man will more often pick the women with the alcoholic drink due to the fact t hat alcohol is a precursor to the possibility of having intercourse. Introduction Alcohol can be traced back to ancient times when Egyptians used beer and wine for ritual and celebratory purposes (Hanson 1995). Osiris, the god of wine, was praised throughout the entire land of Egypt. The Egyptians believed that this important god also invented beer, a beverage that was considered a necessity of life and was brewed in the home. Both beer and wine were created for and sacrificed to the gods. Fast-forward 12,000 years and the variety of alcohol has become so numerous, people no longer need a reason to drink. However, most of the population is unaware of the chemical reaction that is occurring within their body every time they take a sip. It has always been evident that alcohol has an effect on brain function, which in-turn impairs the behavior of a person. Not only has alcohol been linked to multiple physical issues but also mental and emotional. When alcohol is consumed it can create acetaldehyde in the brain to allow a chemical reaction to take place with other ele ments already in the brain waiting to be activated. When acetaldehyde reacts with chemicals such as dopamine, serotonin, and norepinephrine then there is a strong chance that psychoactive alkaloids such as salsolinol will be produced (Sullivan et. al 2010). Acetaldehyde is present everywhere in the atmosphere and may be produced in the body due to the breakdown of ethanol.

Incident 2 Organizational Behavior Essay

Mental Ability We know people with higher levels of mental ability are able to process information more quickly, solve problems more accurately, and learn faster, so you might expect them also to be less susceptible to common deci- sion errors. However, mental ability appears to help people avoid only some of these. 74 Smart people are just as likely to fall prey to anchoring, overconfidence, and escalation of commitment, probably because just being smart doesn’t alert you to the possibility you’re too confident or emotionally defensive. That doesn’t mean intelligence never matters. Once warned about decision-making errors, more intelligent people learn more quickly to avoid them. They are also better able to avoid logical errors like false syllogisms or incorrect interpretation of data. Cultural Differences The rational model makes no acknowledgment of cultural differences, nor does the bulk of OB research literature on decision making. But Indonesians, for instance, don’t necessarily make decisions the same way Australians do. Therefore, we need to recognize that the cultural background of a decision maker can significantly influence the selection of problems, the depth of analysis, the importance placed on logic and rationality, and whether organizational decisions should be made autocratically by an individual man- ager or collectively in groups. 75 Cultures differ in their time orientation, the importance of rationality, their belief in the ability of people to solve problems, and their preference for col- lective decision making. Differences in time orientation help us understand why managers in Egypt make decisions at a much slower and more deliberate pace than their U.S. counterparts. While rationality is valued in North America, that’s not true elsewhere in the world.

Unmanned Aerial Vehicles: Application and Human Factor

Unmanned aerial vehicle, or UAV, is one of the latest aircrafts recently being utilized by the United States Military. Its conception has provided Air Force pilots with assurances of safe return after a combat mission, a feat never before attained in warfare’s history. Since its invention in the 1920’s, several technological advances have been made; extending flight distance and duration capabilities, and pay loading armaments comparable to those of manned fighter jets. Since UAVs are usually controlled by an external pilot on Ground Control Stations, or GCS, it is unavoidable for this system to be faced with human factors, sometimes resulting in mission failures, at times even in aircraft crashes. Unmanned Aerial Vehicles: Applications and Human Factor Recent technology has introduced to us a new form of aircraft in aviation. Perhaps due to the increasing incidents of aircraft accidents during these past decades, which often resulted in the deaths of even the most experienced pilots, airline conglomerates and military authorities had painstakingly searched for the completion of the invention of Unmanned Aircraft Vehicles, or UAV. In this paper, we shall be witnesses to a technology that has the potential to virtually eliminate pilot casualties, whether in war, espionage missions, or even in commercial flights. We shall also see how human factors affect such technology, in terms of control and manipulation of the aircraft, and the causal possibilities of human error in accidents. Background The United States’ Department of Defense defines the UAV as, â€Å"powered aerial vehicles that do not carry a human operator, use aerodynamic forces to provide vehicle lift, and can fly autonomously or be piloted remotely† (Bone, 2003, p. 2). United States’ war on terrorism has put UAVs missions as important in the gathering of intelligence data. Its unquestionable successes in the wars in Iraq, Kosovo, and Afghanistan had opened the military minds on its advantages during wartime. Missions that used to be reserved for Air force top guns, now the UAVs are slowly taking the front seat. UAVs have two obvious advantages over manned aircrafts: first is, they are found to be cost efficient; and it eliminates the dangers faced by the pilots’ during missions (Bone, 2003, p2). Bone cites a number of reasons on the seeming delay of the technology of UAV. One is because the technology to effectively fly a UAV mission has only recently been made available. Another is due to the Air Force’s slowly fading silk scarf syndrome, which gave preference to manned over unmanned flight missions, thus allowing for the UAV to gain more flight hours. Yet another is due to the earlier absence of a global crisis, which could have allowed for a quicker invention of the UAV due to the extreme shortage in the U. S. military of an espionage aircraft (2003, p. 5). UAVs size varies from a few centimeters in length to that of a 747 jet liner. U. S. Department of Defense currently has in its possession five types of UAVs: The Predator and Global Hawk of the Air Force; the Pioneer by the Navy and the Marines; the Hunter and the Shadow by the Army (Bone, 2003, p2). Despite the notion that UAVs have only recently been developed in the United States, it has been in existence in aviation for almost a century. UAVs were first tested in 1920, during World Wa r 1, but the United States did not put it into combat action. It was Germany who had laid the foundations on this technology during World War 2, with the invention of the V-1 Flying bomb. But it was to be in the Vietnam War that UAVs were first used as an espionage plane, with AQM-34 Firebee. Firebee epitomized what the UAV should be: versatile, easy to operate, transportable to other areas, and can easily be converted to payload missiles. In a speech by former President Bush in December of 2001, he had expressed his belief in the UAVs technology, particularly The Predator, as the future of warfare; as stated in a report to the American Congress in 2003 by Elizabeth Bone: This unmanned aerial vehicle is able to circle our enemy forces, gather intelligence, transmit information instantly back to commanders, then fire on targets with extreme accuracy†¦We’re entering an era where unmanned vehicles of all kinds will take on greater importance† (p. 7). U. S. Military U. A. V. s 1. MQ-1 Predator: It is about half the size of an F-16 fighter jet, a tail shaped like an inverted V, and is 27 feet in length and 7 feet high. It reaches a maximum altitude of 25, 000 feet, but for the fitted video cameras to work at its best, it needs to be at about 10,000 to 15,000 feet in altitude. Its take off and landing capabilities are similar to that of the normal aircraft, with the pilot on ground control. The Predator’s main job is airborne reconnaissance and accurate target pinpointing. It is equipped with a Synthetic Aperture Radar, or SAR, enabling it to see through bad weather conditions. Newer models also have capabilities to launch smaller UAVs to carry out varying missions. Each Predator unit’s estimated cost is $4. 5 million, and $30 million for the whole system (Bone, 2003, p. 25). 2. RQ-2 Pioneer: This UAV is the only type on the Navy’s and Marine’s arsenal (Bone, 2003, p. 29). It was obtained by the U. S. Navy in 1986 from Israel after proving its worth with their war with Lebanon. RQ-2 Pioneer is about half the size of the Predator, at 14 feet in length, and its maximum attainable altitude is 15,000 feet. It can remain airborne for 5 hours straight, and since its acquisition, it has accumulated over 23,000 flight hours giving suppo rt to the Navy and the Marines. The cost of Pioneer is estimated at $250,000 to $1 million, depending on the payload (Bone, 2003, p. 30). 3. RQ-5 Hunter: The Hunter weighs 1,600 lbs, is capable of flying at 25,000 feet altitude, and can stay airborne for 12 hours straight. It is equipped with E-O/IR sensor which enables it to fly in night missions. Recently, plans have been made to use Hunter to act as a reconnaissance to a squadron of attack helicopters, such as the Apache and RAH-66 Comanche, to maximize the helicopters’ attack zone. In 2002, a successful experiment was made wherein Hunter’s control was linked to the mainframe computers of the Apache’s during flight missions. The success of the experiment greatly maximized Apache’s efficiency during battle conditions. Weapons payload includes the Brilliant Anti-Armor submunition, or BAT, an effective annihilator of tanks and armored personnel carriers. Hunter’s cost with payload is $1. 2 million, ad the whole system at $30 million (Bone, 2003, p. 33). 4. RQ-7 Shadow 200: Shadow 200, a product of AAI Corporation, is 11 feet in length and has a wingspan of 13 feet. It was strategically designed for brigade operations, thus its range is only 30 nm and has a flight duration of 4 hours. And although its maximum attainable altitude is 14,000 feet, it works best at only under 8,000 feet altitude. The Shadow is equipped with an E-O/IR sensor video camera for day or night missions, and has the capability to transmit data to ground control in real-time. The Shadow cost is pegged at $350,000 while the whole system is at $10. 7 million (Bone, 2003, p. 36). 5. FQM-151 Pointer: All the branches of the U. S. military have, in the past, tried to develop their own type of hand-launched Pointer that measures around 6 feet in the last 15 years, and some of them had been on war missions, particularly in gulf War and Dessert Storm. However, the design officially approved by the Military is the AeroVironment’s Pointer UAV, which weighs 10 pounds, and has a wingspan of 9 feet. It can stay afloat for 90 minutes and has an up to 3-mile operational distance from ground control, within altitudes of 100-300 feet. Pointer UAVs have been best-suited for pay loading experimental miniscule sensors and have been a popular choice for Drug Enforcement Agency, National Guard, and Special Operations Forces (Bone, 2003, p. 37). 5. RQ-4 Global Hawk: This UAV is by far the most expensive ever produced, with per unit cost amounting to $75 million (Bone, 2003, p. 39). It specializes in high altitude, long duration flights that provides near real-time videos of large geographical sections. It is also the first ever UAV to make a successful trans-Pacific flight, when it travelled from California to Australia in April 22-23, of 2001 (Bone, 2003, p. 37). Its effectivity was tested in Afghanistan, when it flew more than 50 combat missions accumulating more than 1,000 combat hours, despite still being on its experimental stage. Global hawk is about the size of a corporate jet, measuring 44 feet in length and weighing 26, 750 lbs. Its maximum altitude limit is almost double than that of a commercial liner, at 65,000 feet, and is capable of flying over 35 hours without refueling. However, Global Hawk’s most apparent advantage is its capability of taking off, flying, and landing autonomously in any kind of weather. Commanders in the battle field aptly call this UAV as, â€Å"the theater commander’s around-the-clock, low hanging surveillance satellite† (Bone, 2003, p. 38). Global Hawk’s pay load consists of a 2,000 pound group of sensors, which is much larger than on any of the previous UAVs. it includes an all weather SAR with a Moving Target Indicator capability, E-O digital camera, IR sensor, and a Signals Intelligence Sensor, or SIGINT, making it a virtually multi-intelligence UAV (Bone, 2003, p. 8). As a testament to its technological superiority, Global Hawk’s radar-sensors and IR cameras were able to accurately pinpoint Iraqi targets in March 24-27, of 2002, despite of having a near-zero visibility on the ground due to a relentless sandstorm in Iraq. 6. Unmanned Combat Air Vehicle: UCAV is the first ever unmanned aero-system designed primarily and purely for combat missions. It is similar in size to the Air Force’s Predator, at 27 feet in length and a wingspan of 34 feet. Equal to manned fighter jets in weaponry and stealth capabilities, the U. S. Armed Forces plan on having one-third of its deep-strike fighter jets be unmanned by the year 2010 (Bone, 2003, p. 42). Due to its 1,000 to 3,000 pound-weapons payload, UCAV’s primary combat mission would be SEAD, or Suppression of Enemy Air Defense, to be followed by precision targeting of enemy installations. 7. Vertical Takeoff and Landing Tactical UAV: Commonly known as VTUAV Fire Scout, it is a helicopter-looking design intended as a replacement for the Pioneer. It is about 23 feet in length, with a maximum altitude of 20,000 feet and maximum flight duration of 6 hours. Its maximum distance of operations is 110 nm from the control ship and has a speed of 115 knots (Bone, 2003, p. 43). UTUAV Fire Scout, unlike the Pioneer which utilizes a net in order to be recovered in a ship, ha the capability of autonomously taking off and landing through the use of sensors. Fire Scout is an unmanned equivalent of the commercial-use Schweitzer helicopter, it ahs an E-O/IR sensor that also serves as a laser targeting designator. It is also capable of mine-detecting, and is equipped with Hellfire missiles. Fire Scouts are being utilized in special operations support and homeland security services (Bone, 2009, p. 4). 8. Dragon Eye: it is the opposite of the Global Hawk in terms of range and size. Being a 5-pounder, with just a 45 inch wingspan UAV, the Dragon Eye can provide marines with over-the-hill surveillance of enemy troops, making it an ideal UAV for urban warfare, chemical, as well as biological-oriented missions. It is portable enough to fit in a backpack and can be launched by hand or with a bungee cord. This UAV can stay aloft for 1 hour, at a height of 300-500 feet, with speeds of up to 40 mph. Because of its small frame, its production cost which includes three planes, is only at $90,000 (Bone, 2003, p. 7). 9. Dragon Warrior: Resembling a small helicopter of about 105 inches long and flight range of 50 miles, and maximum duration of 3 hours, this will be a vertical take off and landing UAV designed for surveillance in urban areas. It will also be equipped with E-O/IR sensor camera and a laser target designator. 10. A-160 Hummingbird: The Hummingbird is also an unmanned helicopter designed to have longer flight duration and distance over the other models, with a range of 2,000 nm and a duration lasting for 48 hours, respectively. With its maximum flight altitude of 30,000 feet and a speed of 130-140kt, it will greatly assist in surveillance, targeting thru laser designation, communications relaying, weapons delivery to infantries, and special operations missions (Bone, 2003, p. 49). 11. Scan Eagle: Boeing’s UAV can be optionally launched from a ship, on land, or even from a submarine. The idea if to have a horde of 4-foot UAVs linked directly on a submarine for reconnaissance purposes. 12. Eagle Eye: This type of UAV takes off like a helicopter, and then flips its rotor blades to fly like an airplane. Its speed is up to 220 knots and has a distance of 300 miles. This type of UAV is suited for patrolling the coastline, locating ships in distress, and also has the capability to transmit videos to command centers. Production cost for the Eagle eye is at $3 million per plane (Bone, 2003, p. 50). 13. Micro Air Vehicle, MAV: unlike the UAVs, MAV is only inches in length, and production costs would be in the thousands and not in millions. As an example, the Organic Air Vehicle, or OAV, measures only 9 inches wide. It has a ducted fan design, and carries an E-O sensor, which comes in infrared or acoustic models. Because of its very small size, MAVs can be programmed for watch-and-stare missions on enemy troops while on air, and also while on land. These MAVs can autonomously lift off and land on itself. Modifications have also been done, resulting in the advent of UCAR, or Unmanned Combat Armed Rotorcraft. These will have the capability as a reconnaissance to ground troops, as well as offensive purposes. It will also be capable of system-linking with other manned and UAVs for performing synchronized attacks (Bone, 2003, p. 51). Human Factor in UAV Flights Since unmanned flights have slowly been gaining popularity in both military and commercial uses, perhaps it will be sooner than we expect for UAVs to replace manned flights permanently. It would be wise for us to give insights on issues concerning cognitive factors affecting the pilots, especially since accident occurrences in UAV flights have been proven to be over thirty times more common than in manned aircraft flights (McCarley & Wickens, 2005, p. 2). It is also possible for UAV pilots to be manning more than one aircraft simultaneously, entailing never-before-encountered workload pressures. Manual v Automated Flights 1. It has been widely accepted that the effect of automation has not resulted in the elimination of human workload but the introduction of new ones, forcing the pilots to develop new strategies (McCarley & Wickens, 2005, p. 4). The changing of strategies is often the result descriptive of an imperfect system, not of the computer software type, but of the factors that even a perfectly-running automation system would not be able to detect, such as the icing of an UAV wing. 2. The present UAV take off and landing automated procedures differ according to the model. Such that the Hunter and the Pioneer require an on-site external pilot; the Predator to be controlled on a separate aircraft within the Ground Control Site; while there are some cases, as in Global Hawk, where full automation is integrated. These differences seem to be significant, take off and landing errors make up for a majority of accidents attributed to human factors; Hunter with 67% and the Pioneer with 78%, both are externally controlled (McCarley & Wickens, 2005, p. ). 3. An external pilot of a UAV basically relies on computer imagery in controlling the aircraft. The visual quality of the imagery, however, has the possibility of being diminished due to factors affecting bandwidth, resulting in poor resolution or a delay in image uploading. Situations such as these may prejudice overall aircraft control and visibility of air traffic. This poses a clear danger in military missions, more so in the planned commercial implementation of autonomic control of commercial flights. 4. On way of solving the problem stated in #3 is by the use of enhanced reality, or synthetic vision (McCarley & Wickens, 2005, p. 7). In this system, images from the actual camera shots of a UAV will be converted to display landmarks on a given terrain, thus creating a virtual reality world that the external pilot can manipulate. The problem with this system is that pilot’s over reliance on synthetic imagery would lead to a possible neglect of some natural landmarks not visible in the imagery system. Thus, using this method would be beneficial for the UAV performance but comes with a potential risk. . One of the resulting effects of separating the pilot from the aircraft is that the pilot would be denied of his real-time sensory reactions otherwise available in a manned aircraft, and that he would have to rely on computer monitors provided for by the cameras onboard the UAV. Hence, we can conclude that the external pilot only functions in a relatively sensory isolation from t he UAV he is controlling. It would be of utmost importance for the developers to design an alarms system to keep the pilots abreast of the real-time environmental situations and probable system failures. . Since UAV pilots are not in danger of injury or death in the event of their aircraft crashing, this could, in theory, prove to be a big difference in the pilot’s risk-taking decisions, such as in going through a flight plan on a bad weather. Sensory isolation factor could be magnified during these situations (McCarley & Wickens, 2005, p. 10). 7. The accepted norm during long endurance UAV flights had been to switch control among different external pilots within a single flight. This process usually takes on three types: First is the transfer of UAV control from one Ground Control Station to another; second is through the transfer of control from one team of operators to another, within the same GCS; and last is through the transfer of control from one pilot to another within the same team. It has been documented that a significant number of UAV accidents happened during the transfer from one pilot to another, because the GCS taking over control of the UAV was not properly briefed beforehand (McCarley & Wickens, 2005, p. 0). 8. Instances of a total failure of the Ground Control Station-UAV communications link would prove to be disastrous. This scenario can be considered as a human factor because of the need for the Automated Traffic Center, or ATM, to be aware of the default programs of the UAV system in order to properly manage air traffic within their area. It would also be of the utmost importance for the external pilots themselves to be aware of the comm unications link failure as quickly as possible. 9. Researches on whether experienced manned pilots are better operators than novice manned pilots have ended in differing conclusions. Although generally, as the experiments revealed, experienced manned pilots reached the desired level of performance in landing and basic maneuvering skills faster than that of the novice’s. Other studies, however, based on the Army’s Job Assessment Software System, or JASS, revealed that piloting skills does not constitute a great deal in UAV operations, thus making the selection of top pilots as UAV operators insignificant (McCarley, & Wickens, 2005, p. 3). 10. Questions on medical qualifications of the UAV operator should also be brought into light. Since physical factors concerning high altitude temporary mental perception failure does not concern AUV pilots, still some type of medical fitness qualifications must be practiced. These must be able to determine if: the said qualifications should be more stringent or less for the UAV pilo ts; and, work duration limits should be established for long endurance missions. 11. Since the pressures and work load of a UAV pilot differs from that of a manned aircraft, and since formal training in flight schools are usually focused on instructing pilots for manned vehicles, which constitute less amount of time on simulations and more on the actual flight, the need arises for a training more attuned to giving more flight simulations to pilots of UAVs. This should be able to determine up to what extent trainee pilots should spend time on simulations in order to obtain a UAV certification. 12. Technological researches must be made to improve on the controls of the external pilot. At present, the controls of the UAV are similar to that of a radio-controlled hobbyist’s plane. This design poses a problem in the directional movement of the UAV with respect to the controller. As such, when the UAV and the pilot differ in position by 180 degrees, a rightward movement on the rudder will result in leftward movement of the UAV, and vice versa. Control rudders must be made to conform to the principle of human motion compatibility as to avoid further confusion for the pilot (McCarley & Wickens, 2005, p. 6).

Should You Go to College 4 Pros and 3 Cons

Should You Go to College 4 Pros and 3 Cons SAT / ACT Prep Online Guides and Tips The decision to attend college is a big one. Getting a college degree takes time: at least four years for most people. Getting a college degree also costs money: tens of thousands of dollars for most people. You might be asking yourself, "Is it worth it? Should I go to college?" In this article, I'll explain the benefits of going to college and detail some of the potential drawbacks. Furthermore, I'll give you all the information you need to decide whether or not you should pursue a college degree. 4 Major Benefits of Going to College Going to college can make you richer, happier, and healthier- sounds good to me! Here, we take a look at the four biggest benefits of attending college. #1: There Are Many Financial and Career Benefits Let's start by considering the financial advantages of a college education. In 2015, college graduates with a bachelor’s degree earned 56% more per year than those with a high school diploma or its equivalent. In addition, according to the Bureau of Labor Statistics, the median weekly earnings in 2017 for those with a bachelor's degree was $1,173, compared with $836 for those with an associate degree and $712 for those with only a high school diploma. Here's one of the most cited statistics that shows the benefits of a college education: a person with a bachelor’s degree will, on average, earn almost $1 million more over the course of her lifetime than somebody with just a high school diploma will. While I don't think money should be the biggest priority in anyone's life, there's no doubt that a higher salary will give you more opportunities, alleviate stress, and allow you to more easily support a family. Moreover,college-educated Millennials have much lower unemployment and poverty rates. According to a Pew Research study in 2013, 12.2% of Millennials aged 25-32 with just a high school diploma were unemployed, whereas a much lower 3.8% of those with at least a bachelor's degree were unemployed. In addition, those who attended college are more likely to get married and less likely to be living in their parents' homes.Statistics indicate that attending college has more economic benefits for Millennials than it did for previous generations. Going to college might be more important now than ever before! Finally, a college degree is required for many entry-level jobs.According to a study done by the Georgetown Public Policy Institute, by 2020, 65% of jobs will require postsecondary education and training beyond high school, and 35% of jobs will require at least a bachelor’s degree. As you can see, there are tons of financial benefits to getting a bachelor's degree. But what about the professional advantages? In college, you can make connections that will help you land a good job after you graduate. Experts estimate that70%-80% of jobs aren’t advertised publicly.Often, you simply have to know the right people to secure employment. Many companies also offer internship programs to college students that can lead to full-time employment after you graduate. Furthermore,most colleges offer free career counselingand can put you in touch with employers and alumni who can help you find a job. Colleges will often have job fairs as well,where recruiters come to campus looking for qualified students to work for their companies.These fairs give you an opportunity to form relationships with company representatives who can assist you professionally. Lastly, many of your peers will probably go on to professional success. Your college friends might one day be able to offer you a job, refer you for a job, or make a lucrative business deal with you.As a college student,you'll (likely) be surrounded by many motivated, talented people who, in the future, will want to work with those they know and trust- and this could very well include you. #2: You Get to Explore Your Interests College opens up a whole new world to you academically.In high school, you generally only have a choice of a handful of elective classes, but in college you can literally choose from among hundreds of classes and majors. While there are core requirements at most colleges, for the most part, you can decide what you want to study and take classes in subjects you want to learn more about.Many students are able to spark academic passions in college. You could take classes in anthropology, psychology, sociology, microbiology, or osteology.I have several friends and former students who were inspired by college classes that positively changed the course of their academic and professional lives. Also, while in college, you'll have the chance to pursue tons of extracurriculars and opportunities you might not otherwise have done. These activities can become lifelong passions, help you form meaningful relationships, and even prepare you for a future job. For example, you could write for the campus newspaper, or you could be aDJ for the school radio station.You could dance for a hip-hop group, or join acampus organization that provides tutoring to underprivileged kids. You could help build houses for those in need.You could work on political campaigns or join groups that advocate for various social issues. The choice is yours! Howard Stern started his career working at the radio station at Boston University. #3: You'll Have Fun and Make Friends Almost everybody I know thoroughly enjoyed their college experience. Too often people discount the importance of fun when it comes to education, and some of my best memories and most fun times are from my college years. On a college campus, you can attend parties, plays, sporting events, and concerts; you can also create your own random fun with your peers. Most schools bring exciting events and speakers to their campuses, too. Colleges will often host famous musicians and comedians. For example,The Weeknd has performed shows at Syracuse, Northeastern, Lafayette College, and the University of Minnesota, while Drake has performed at numerous colleges, including Howard, SUNY Purchase, and the University of Kentucky. Besides entertainers,world-renowned academics and political figures often give speeches on college campuses.Hillary Clinton made appearances at Philander Smith College in Little Rock and Morningside College in Sioux City, whereas Ben Carson spoke at Alma College in Michigan. Colleges will also sponsor parties and other on-campus events that are just meant to be fun and facilitate social interaction.At Stanford, there’s a tradition known as Full Moon on the Quad. On the first full moon of the school year, students gather in the quad, and the seniors welcome the freshmen by kissing them. There’s a lot of kissing. It might not be hygienic, but it's memorable. Most of my closest friends are people I met during college.In college, you get to befriend people from all over the US and even other countries.A big part of the college experience is having the opportunity to learn from and interact with people from diverse backgrounds. Overall, you have the chance to study, live, party, and participate in extracurricular activities with your peers. There will probably be no other time in your life when you get to spend as much time with your friends, and the amount of quality time you get to spend with them will form the foundation for meaningful lifelong friendships. #4: It Gives You Space for Self-Improvement For many students, college is the first time in their lives they’re not living at home. During college, they learn to be self-sufficient.They learn domestic skills and budgeting- even how to motivate themselves without parental encouragement.At the same time, most college students can still go home or call home if they’re in need of some money or advice. Many of the people I know who didn’t go to college remained at home for at least a couple of years after high school. Though they had more freedom than they did during high school, their routines and mindsets didn’t change nearly as drastically as those of my friends who went to college.In my experience, even students who live at home and commute to college experience more growth than those who bypass college. Whether you go to an in-state or out-of-state school, your college will likely expose you to a new city and environment.I grew up in California, but Stanford (my alma mater) was a six-hour drive from where I lived. I was able to experience life in Northern California and the San Francisco Bay Area, which has a different vibe, culture, and climate from Los Angeles. I enjoyed living in the bay, and I’m grateful that I was able to have the opportunity to live in a different environment. Furthermore, most colleges have study abroad programs that can give you a chance to take classes in countries around the world. At Emerson College, you can spend a semester in a 14th-century medieval castle in The Netherlands.At the University of Chicago, you can studyabroad in Paris, Beijing, Barcelona, Berlin, Kyoto, Bologna, Cairo, Istanbul, Jerusalem, Edinburgh, Hong Kong, London, Oaxaca, Vienna, Milan, and a few other places, too. You can learn about the world by traveling and studying in countries around the world. Finally, people who go to college tend to be healthier.According to a CDC report, people with a bachelor’s degree live about nine years longer than people without one.They’re also less likely to smoke and more likely to exercise. Similarly, according toa study published by the American Journal of Public Health, people who get a bachelor’s degree after 25 years of age exhibit fewer depressive symptoms and have better self-rated health at midlife. College and apples are good for your health. 3 Possible Disadvantages of Attending College Even though attending college can offer you many benefits, there are potential drawbacks. Note that you only get many of the benefits of going to college if you're able to graduate. A 2019 NPR article reported that only 58% of students who enrolled in college as first-time students in the fall of 2012 had earned a degree. Now, let's take a look at the three biggest cons of attending college. #1: There's the Risk of High Costs and Potential Debt College is really, really expensive, with costs continuing to rise, and many college graduates are burdened with astronomical student loan debt. The College Board estimates that the average cost of attendance for an in-state public college for 2018-19 is $10,230, whilethe cost of attendance for a private college averages $35,830. Remember, though, that most students receive financial aid that covers at least part of the cost of attendance if they demonstrate financial need. Unfortunately, many students don’t receive the aid they need to fully cover the costs. As a result, they take on unsubsidized student loansto finance their college education.Sadly,student loan debtincreased from $260 billion in 2004 to $1.5 trillion in 2019. Average debt per student in the class of 2017 was $28,650- that's a pretty staggering amount. Overall, student loan debt can dramatically impact your life after your graduate. It can affect the jobs you take and cause you to delay buying a house or starting a family. #2: The Financial Benefits of College Might Be Overstated The claim that college graduates earn $1 million more in their lifetimes might actually be skewed by graduates from top universities. A 2018 study by PayScale.com found that there are only five schools (out of 1,878 four-year schools) at which earning a college degree can get you a $1 million return on investment. Basically, the reported number that college graduates make $1 million more over the course of their professional lives is not that accurate. Moreover, it's important to note that while most people are in college, they’re not working or only working part-time.So in addition to the financial costs and debts you're incurring while in college, you probably won’t be able to get the salary you could be making from working a full-time job during the four to six years you’re in school. #3: College Might Not Actually Make You Smarter The last con of attending college is that going to one might not actually increase your intelligence. A 2011 studyfoundthat 45% of 2,322 traditional-aged college students studied from 2005 to 2009 made no significant improvement in their critical thinking, reasoning, or writing skills during the first two years of college. After four years, 36% showed no significant gains. Given the cost of attending college, you'd hope that higher education would have a dramatically positive effect on these skills for all students- but this might not actually be the case. Should IGo to College? How toMaketheRight Choice for You Admittedly, I’m somewhat biased because I’ve spent years stressing the importance of attending college to high school students. However, I do recognize that college might not be for everyone. Other than the pros and cons of college I mentioned previously, here are some additional factors to consider when deciding whether or not to attend college. Very Few College Graduates Regret Going to College The vast majority of college graduates are glad they went to college.Many college grads have debt and some have a job they could have gotten without their degrees, but very few people regret going to college. According to 2012 datafrom the Heldrich Center for Workforce Development at Rutgers, only 3% of college graduates from 2006-2011 wish they had not gone to college. You’ll Have More Options With a College Degree You might be planning to enter a trade that doesn’t require a college degree and will provide you with a good salary and benefits.However, if you end up deciding that you don’t like that field after a few years and you don’t have a college degree, your employment options will be limited. Also, if you take up a trade that requires physical labor and you suffer an injury, you might struggle to find work without a college degree. There Are Ways to Pay for College You might be turned off by college because of how much you think it will cost you. But remember that you might not know your out-of-pocket expenses until you get accepted to college and get a financial aidpackage. In reality, there are manygrants and scholarships that can alleviate the financial burden and make college more affordable for you. You Might Not Need College If You’re Already Successful If you’re one of those rare people who has already achieved tremendous professional success before attending college, then going to college might not benefit you much financially. For instance, say you get drafted in the first round of the draft by Major League Baseball and are offered a multi-million dollar signing bonus. Nobody would fault you for bypassing college. After all, you can always take college classes in the off-season or get your degree when you're done with your playing career. If you’re a mini Mark Zuckerberg or starring in your own sitcom, going to college might not lead to a higher income or a better job after you graduate. Bill Gates and Miley Cyrus were able to do OK professionally without college degrees! You Might Not Be Academically Inclined Most people are capable of doing college-level work if they’re motivated and apply themselves. That being said, some people just detest school or don’t have the aptitude to do well in a college environment. Keep in mind, though, that college gives you so much more freedom than high school to explore your academic interests and find the fields in which you can excel. Similarly, if there's a subject that confuses you and that you absolutely abhor, you can probably avoid taking classes in it in college. wecometolearn/Flickr Conclusion: Should You Go to College or Not? There's no denying that college offers many financial, professional, and personal benefits. Numerous studies have shown that college graduates have far better financial and job prospects than those who don't attend college. What's more, few people regret going to college despite the tremendous amount of student debt and the less-than-ideal economy. If you're worried about the cost of attendance, make sure you know about financial aid and how to limit your debt when you graduate. College is an investment that pays off for the vast majority of people who graduate. Admittedly, some people don't need college to achieve their personal or professional goals. While you can of course be successful without a college degree, college graduates tend to fare better. If you're considering college, make the decision that will benefit you the most now and in the future. What's Next? Decided you want to go to college?

More Answers to Questions About Commas #2

More Answers to Questions About Commas #2 More Answers to Questions About Commas #2 More Answers to Questions About Commas #2 By Mark Nichol Here are three recent questions from readers about the use of commas, along with my responses. 1. Can you tell me why there should be a comma in this sentence: â€Å"Such programs will also reduce operations costs and indemnity payments, and improve communications between employer and employee.† It seems like there shouldn’t be, because these aren’t two independent clauses. It’s common for writers to insert a comma before a conjunction in a sentence when the conjunction does not begin a new clause but the phrases before and after it include their own conjunctions. This effort to make the sentence’s organization more obvious is not wrong, but it’s unnecessary. The sentence structure becomes clearer if the first verb, the one that’s overworked in its efforts to support the entire sentence, is relieved by being repeated in a parallel position after the major conjunction: â€Å"Such programs will also reduce operations costs and indemnity payments and will improve communications between employer and employee.† 2. I saw this sentence in one of your posts lately: â€Å"It enables individuals and groups to meet online to collaborate, and to share presentations, applications, or their entire desktop, while increasing reliability and security and reducing costs.† Why is there a comma after collaborate? The first comma in this sentence does not have the same function as the extraneous one in the previous example. It is the first in a pair of commas that mark a parenthetical. The phrase â€Å"and to share presentations, applications, or their entire desktop† may be omitted from the sentence, and the remaining statement will still be grammatically sound. 3. In â€Å"Our vision statement is a succinct way of explaining our purpose to others, be it our own staff, our residents or community clients or the wider public,† the two ors make it clunky to me. The or between â€Å"our residents† and â€Å"community clients† signals that the sentence is about to end, and then theres another or! Should I have a comma in there somewhere? If your style calls for serial commas (â€Å"a, b, and c†), insert a comma after clients: â€Å"Our vision statement is a succinct way of explaining our purpose to others, be it our own staff, our residents or community clients, or the wider public.† If not (â€Å"a, b and c†), leave it as is. However, if that solution seems clumsy to you (I don’t find the final or confusing), separate â€Å"our residents or community clients† into two items: â€Å"Our vision statement is a succinct way of explaining our purpose to others, be it our own staff, our residents, our community clients or the wider public.† (Insert a comma after clients, or don’t, depending on whether you insert or omit serial commas.)

Paradise Lost by John Milton term paper Essay Example | Topics and Well Written Essays - 2250 words - 1

Paradise Lost by John Milton term paper - Essay Example venge over this, Satan or the Lucifer, in other words, decided to bring the downfall of man by making them to eat the forbidden fruit in the Paradise or the Garden of Eden. Consequently, one may have the temptation not to believe in Christianity by basing on the reason on what could make God allow Serpent to revenge on His creation (God) if He truly loved them. The story of the Paradise begins from hell where both the Lucifer and his followers recover from the defeat after losing the battle initially in the war they had with God. For example, they constructed a monument that they referred to the Pandemonium where they were weighing the options of making a return to battle or just to forfeit it by accepting the defeat. Consequently, they also had the considerations of exploring the new world contained in the prophesies of creation for effecting the safe infliction of their planned revenge against mankind. As a way of enforcing their mission with full force, Satan decided to undertake the task alone minus engaging his followers. He feared that his followers might suffer extreme damage or run away from him during the battle (Driven, 45). At the onset of the mission, Satan met with his offspring who were the Death and the Sin. Thereafter, they unbarred the gates for him. Satan proceeded with his journey to the chaos until he ensured that he ha s the visualization of the Universe floating next to the globe that was the heaven. Through this instance, God predicted the fall of man when He saw Satan moving in the world. In consequence, Gods son who was at His right hand decided to sacrifice himself for the purpose of saving the mankind from the wrath of destruction by Satan. However, Satan still managed to maneuver his ways into the new universe where he flew to the sun and proceeded to trick angel, Uriel into showing the direction leading to the home of the man. After the guidance to the way to the home of the man by the deceived angel Uriel, Satan managed his ways into
