Platypus Essays - Monotremes, Sleep, Dream, Neurophysiology

Platypus The platypus, apparently, is a surprisingly deep sleeper. What's more, it spends more of its time in so-called 'REM' sleep than any other mammal. These are the conclusions of a study on sleep in the platypus by Jerry M. Siegel of the Sepulveda Veterans' Affairs Medical Center, North Hills, California and colleagues. Their report appears in a special number of Philosophical Transactions of the Royal Society devoted to the biology of the platypus (Ornithorhynchus anatinus), celebrating the bicentenary of the discovery, in Australia, of this remarkable animal. 'REM' stands for 'rapid eye-movement' and is the kind of sleep in which the brain can be more active than in it is while awake, the animal twitches, and the eyelids flicker ? hence the name. In humans, REM sleep is associated with dreaming. But does the platypus have an extraordinarily rich dream life? Possibly not, say the researchers: "cats, opossums, armadillos and other mammals not known for their intellectual achievements have far more REM sleep, whether calculated in hours per day or as a percentage of total sleep time, than humans." And why study sleep in the platypus anyway? After all, the platypus is an obscure and extremely primitive creature, distantly related to humans. The answer lies in that primitive state: studying the physiology of the platypus could yield clues about the life and behaviour of the very earliest mammals. The platypus belongs to a group of mammals with very ancient roots. Apart from the platypus itself, the group ? the monotremes ? includes two species of echidna, or 'spiny anteater'. All three species are confined to Australasia. Monotremes lay eggs, like birds and reptiles, but unlike all other mammals. They also have a range of other reptile-like anatomical features, features that have been lost in more 'advanced' mammals. Researchers think that monotremes have been distinct as a group for at least 80 million years, long before the dinosaurs became extinct. Monotremes have taken a cameo role in studies on the evolution of mammalian brain function. A study in 1972 suggested that the echidna Tachyglossus had no REM sleep. This was important, because it implied that REM sleep must have evolved in higher mammals. Subsequent research made this result look anomalous, as REM-like sleep phenomena have since been observed in birds and some reptiles: in which case, the echidna may have lost the capacity somewhere in its evolution. This is the conundrum that Siegel and colleagues have been investigating. First, it turns out that the term 'REM' is a misnomer: animals may show REM sleep even though their eyes don't move, and their bodies don't twitch. REM is properly defined as a characteristic pattern of activity in the brain, generated by specific neuronal pathways in the brainstem ? whether or not this activity is carried forwards into the 'higher' centres of the brain (where it is manifested as dreaming). Recordings from discreetly implanted electrodes show that the echidna does, after all, show a kind of REM sleep generated by the brainstem, even though it is rather muted and the animal shows no outward signs. Young animals show more REM sleep than older ones, and it could be that very young echidnas have a more active sleeping life (including twitching) than older ones. The platypus, though, shows all the classic outward signs of REM sleep. Indeed, an account from as long ago as 1860, before REM sleep was discovered, reported that young platypus showed 'swimming' movements of their forepaws while asleep. Despite these differences, the REM sleep of the platypus and the echidna is confined to the brainstem: the forebrain shows the regular, steady patterns of neuronal activity associated with deep, dreamless sleep. This suggests that for all their REM sleep, monotremes do not dream. These findings set our understanding of the evolution of sleep on a firmer footing. It now seems that the 'core' brainstem activity manifested as REM sleep has extremely ancient roots, going back to the reptilian acnestors of mammals as well as birds. The elaboration of REM sleep into the forebrain is a later innovation: but whether it evolved once and monotremes have since lost it, or if it evolved more than once, is something that only more work on birds and reptiles can establish. The platypus, apparently, is a surprisingly deep sleeper. What's more, it spends more of its time in so-called 'REM' sleep than any other mammal. These are the conclusions of a study on sleep in the platypus by Jerry M. Siegel of the Sepulveda Veterans' Affairs Medical Center, North Hills, California and colleagues. Their report appears

FADEC-Full Authority Digital Engine Control Essay Essays

FADEC-Full Authority Digital Engine Control Essay Essays FADEC-Full Authority Digital Engine Control Essay Paper FADEC-Full Authority Digital Engine Control Essay Paper FADEC is a system comprising of a digital computing machine ( Electronic Engine Control EEC ) and the other accoutrements that control all the facets of aircraft engine public presentation. FADEC is made for Piston engine and jet engines both but they differ in the manner of commanding the engine. A primary ground for the rapid technological advancement of the U. S. LCA industry has been its ability to pull on and benefit from inventions in other high-technology industries. For illustration. high velocity supercomputers accurately model aircraft air flows without the assistance of air current tunnels. Computers besides have been incorporated significantly in LCA cockpits as planimeters of information. With the increased use of flat-panel shows that project the image of an electromechanical gage. several shows either can be transferred separately to assorted panels or superimposed on one panel at the pilot’s discretion. In add-on. computing machines have aided in the development of Full-Authority Digital Engine Control ( FADEC ) systems. FADEC allows for improved monitoring and adjusting of engine runing parametric quantities. such as fuel flow and velocity. : This enhanced control of aircraft engines has led to a lessening in both fuel ingestion and care demands. History of FADEC A FADEC ( Full Authority Engine Control ) is an electronic system that controls all the important parametric quantities of aircraft power workss. One of the system roles is to take down the cognitive burden of pilots while they operate turbojet engines. and to cut down the happening of pilot mistakes. The purpose of any control system is to let the engine to execute at the maximal capacity for a status. The original engine control system is mechanical linkages and controlled by the pilot. By utilizing throttle levers which are connected to the engine. the pilot could merely command power end product. fuel flow. and the other parametric quantities of engine. These mechanical agencies of engine control was an debut of parallel electronic engine control. Analog electronic control varies an electronic signal to pass on the coveted engine scenes. This system was foremost introduced as an indispensable portion of the Rolls Royce Olympus 593 engine. The 593 engine was regarded best for the celebrated supersonic conveyance aircraft. Concord. In the 1970’s NASA and Pratt and Whitney foremost experimented on FADEC. it was foremost flown on F-111 fitted with extremely modified Pratt and Whitney TF30 left engine. The experiments led to Pratt A ; Whitney F100 and Pratt A ; Whitney PW2000 being the first civil and military engines severally fitted with FADEC and subsequently the Pratt A ; Whitney PW4000 as the commercial â€Å"Duel FADEC† engine. Rolls- Royce financess about 20 UTCs working on cardinal countries of engine engineering. Most of the UTCs focal point on facets of production engineering. e. g. high temperature stuffs and burning. The York UTC is comparatively unusual in that if focal points on procedure issues. In peculiar the York UTC investigates systems and package technology processes for the development of full Authority Digital Engine Controllers ( FADECs ) . A FADEC is a complex hydro-mechanical system which carries out all cardinal engine control maps. typically: Thrust provision- changing fuel and air flows through the engine to supply managed push. Thrust control- in peculiar proviso of contrary push from the engine for braking on landing. Heat management- ensures that parts of the engine are cooled suitably. Airframe communication- having control commands from the airframe ( e. g. from the pilot ) and returning engine position indicants. Fault management- detection mistakes in the engine position indicants. ( Henderson. pg. 38 ) Maintenance- entering mistakes informations for on land engine care. At the bosom of the FADEC is a computing machine system known as an Electronic Engine Controller ( EEC ) . The EEC and its package signifier a difficult real-time system and. typically. the system is safety critical. I. e. failures could potentially take to a loss of push and possibly of the aircraft. Functions of FADEC-Full-Authority Digital Engine Control There must non be any signifier of manual override available for Full Authority Digital Engine Control. This to the full places full authorization upon the operating parametric quantities of the engine to computing machine. If FADEC would neglect the engine would besides neglect. If the engine would be controlled digitally and electronically. it would be considered as Electronic Control Unit ( ECU ) or Electrical Engine control ( EEC ) . FADEC plants by the given input variables of the current flight place like engine temperatures. air denseness. engine force per unit areas. restrict lever place and others. The EEC receives inputs and analyzes them up to 70 times per second. Engine operates many parametric quantities like bleed valve place. stator vane place. and fuel flow and others are computed from this information and applied as appropriate. FADEC controls most of the maps like re-starting and get downing. The basic intent of FADEC is to give optimal engine efficiency for a given flight status. FADEC allows having engine care studies and plan engine restrictions. For case. FADEC can be programmed to take the necessary steps without pilot intercession to avoid transcending an engine temperature. Turbine engines The fuel control system on the turbine engine is reasonably complex. as it monitors and adjusts many different parametric quantities on the engine. These accommodations are done automatically and no action is required of the pilot other than get downing and closing down. No mixture accommodation is necessary. and operation is reasonably simple every bit far as the pilot is concerned. New coevals fuel controls incorporate the usage of a full authorization digital engine control ( FADEC ) computing machine to command the engine’s fuel demands. The FADEC systems addition efficiency. cut down engine wear. and besides cut down pilot work load. The FADEC normally incorporates back-up systems in the events computing machine failure. Jet engines Modern jet engine is really considerable: it forms an built-in portion of the engine and is indispensable for its operation. In many instances some of the engine control electronics is physically mounted on the engine. Many modern jet engines have a full authorization digital engine control system ( FADEC ) . This automatically controls the flow of fuel to the engine burning Chamberss by the fuel control unit so as to supply a closed cringle control of engine push in response to the throttle bid. The control system ensures the engine bounds in footings of temperatures. engine velocities and that the accelerations are non exceeded and the engine responds in an optimal mode to the throttle bid. The system has what is known as full authorization in footings of the control it can exert on the engine and the high unity failure endurance control system is indispensable. Otherwise a failure in the system could earnestly damage the engine and guess the safety of the aircraft. A FADEC engine control system is therefore similar in many ways to a FBW flight control system. ( Collinson. pg. 9 ) FADEC is used in about all jet engines and new Piston engines on chopper and fixed winged aircraft. With the operation of the engines so to a great extent trusting on mechanization. the most of import concern is its safety. Redundancy is provided in the separate indistinguishable digital channels. FADEC monitors a distinct and digital informations coming from the engine subsystems and assortment of parallel. and supplying for mistake tolerant engine control. In the civilian conveyance aircraft flight. the flight crew enters the appropriate informations to the day’s flight in the ( FMS ) flight direction system. The FMS reads the informations like air current. runway length. cruise altitude etc. and so calculates the scenes for the different stages of flight. The flight crew advances the throttle to take off which contains no mechanical linkage to the engine. The flight crew cheques that they have simply sent an electronic signal to the engines as no direct linkage has been moved to open fuel flow. This is the same stage for all type of flights like sail. ascent etc. The FADECs compute and use the appropriate trust scene. During the flight little alterations in operation are being made to keep efficiency. Full Authority Digital Control ( FADEC ) system is configured to guarantee safe. stable and dependable engine operation at all the points in the flight envelope. Control Torahs are indispensable for supplying the coveted engine operations safely. The control Torahs must be verified and validated before the engine starts for a flight. Reference Collinson. G.

The Difficulty of Connecting with the Parties Responsible for Addressi Assignment

The Difficulty of Connecting with the Parties Responsible for Addressing Important Problems - Assignment Example It took an extraordinarily long time for the emergency response services to start responding to the effects of the hurricane and even then, there were evident signs that the emergency services were clearly struggling, and were having trouble coping with trying to help the hurricane survivors (Kettl, 2009). In contrast to this, Kettl’s mother in law was seen to receive an excellent end of life case through the government’s Medicaid. All her wants and needs were adequately and sufficiently addressed by the program which was seen to be doing an excellent job at ensuring that it was able to deliver quality and timely services (Kettl, 2009). Through the aid of these two illustrations, Kettl is able to identify that although the United States government has consistently proven to be good at the delivery of the basic services like medical care, garbage collection, and management of pension schemes. It had proven to be quite incapable of handling large-scale and unexpected problems like the effects of hurricane Katrina. Kettl argues that as opposed to the standard â€Å"vending machine model† that has been proven to work just fine when it comes to handling repeated problems that might face the system such as garbage collection, the handling of disasters is seen to require concentrated public-private and multi-agency partnerships (Kettl, 2009). Kettl argues that it is increasingly becoming more and more difficult for the government to adequately meet the needs and demands of its citizens. As a result of this increasing difficulty for citizens to connect with the government so as to have their important issues addressed, there has been a general drift towards the creation of a situation whereby most of the work geared at meeting the demands for better and more services by the government has now been placed in the hands of private contractors (Kettl, 2009).     

Criminological Theories A comparison Between Control Theories and Essay

Criminological Theories A comparison Between Control Theories and Scocial control Theories of Crime - Essay Example The social control they describe is not through Laws, but through Beliefs and societal Norms. However, these norms could later evolve into Laws, ethics, Etiquettes and Customs . The Control is effected through establishing conformity and compliance to these norms. SOCIAL CONTROL THEORIES are viewed along two perspectives. The Macro social and Micro social perspectives . The Macro Social Perspective examines the Formal Control Systems which include the Legal systems, Law enforcers, lobbies which influence laws, which exercise control over the society. Micro Social Perspective, studies the INFORMAL control systems. exercised by Families, religious and educational institution and peer groups. This Informal control manifests as Bonding ,Re Integrative Shaming, Attachment, and Learning through Role Models. The control theories focus on a person's Relationship to their parents, teachers, parish priests and coaches who act as agents of socialization -.A child's Effective interaction with these agents translates into bonds with society.(Hirschi1960) Control Theories study the internalization of Moral codes and the stakes and ties in the community the individuals develops, which make them to voluntarily limit their deviant behaviour.These are Informal controls exercised by social and familial bonds. It is more a "self concept". The most influential among the Control Theories are, John Bolwlby 's Attachment Theory, Travis Hirschi's Social Bonds Theory , the Age Graded Life course Theory of Sampson and Laube and the General Theory of Crime by Gottferson and Hirschi (1999) The Control Theory of Delinquency was presented by Travis Hirsche in 1969. It emerged from the Social Disorganisation Theory (Western Criminology Review)which was slowly losing its prestige at that time. Hirschi took his cue from this theory which held that Disorganised communities generate crime as informal social controls have broken down.It was John Bowlby who first floated the emotional aspect in social control in his Attachment Theory in 1969.Hirschi synthesizes both these perspectives . Hirschi's Control Theory posits that it is not so much the Individual's personality, but his social Relationships and social bonds which determine the deviance or conformity of his Behaviour. Absence of Control exercised by those bonds left him free to weigh the profits against risk . Attachment to others make him less likely to be deviant. Both Hirschi and Bowlby stress Parental upbringing in instilling socialization. The accrual of emotional investment by parents develops Empathy in the individual , which heightens his control and help him to Desist from acts violating the conventions. .The other Control theories, The General Theory of Crime, The Age Graded Life Course Theory that followed, acknowledged the SELF concept .They explained how at a Micro perspective, Informal social bonds which are at first external, become internalized . Gottferson and Hirschi (1990) , and later,Sampson and Laube (1993)in their Age Graded Life Course Perspective said that there is a relationship of causes between the later deviant behavior and the

Is Astrology A Pseudoscience?

Is Astrology A Pseudoscience? In order to ascertain whether or not something is a pseudoscience or fake science, one must first know what pseudoscience is. Here, I am going to illustrate the many different points which distinguished philosophers such as Michael Radner, Densie Radner and Paul Thagard have made on what is a pseudoscience to evaluate astrology, which is the study of how the heavenly bodies such as the planets and the constellations affect us and instead offer that Astrology is simply not science, much like religion or poetry is not like science. Already, if one were to look up Astrology in a collection of online dictionaries, there will be definitions such as a pseudoscience claiming divination by the positions of the planets and sun and moon however wether the writer of such definitions knows why or how astrology is a pseudoscience remains a mystery, perhaps they, like the 192 scientists and 19 noble prize winners who signed the statement against astrology Bart Bok, Paul Kurtz and Lawrence Jerome, support it being a pseudoscience because it goes against their instincts and rational thinking which is really not enough evidence for anything to be classified as a pseudoscience. For example the three most important issues raised by the statement which was signed by these scientists proclaimed that: Astrology originated as part of a magical world view. However so did chemistry (it arose from alchemy) and doctors use to believe that the body was made of humours and today even honour the Hippocratic origins of medicine by still making the Hippocratic Oath. The planets are too distant for there to be any physical foundation for astrology. While the planets are distant, there are certainly ways distant objects can influence our lives. For example if the sun were to explode, that would certainly make an impact upon our daily lives. People believe in astrology out of longing for comfort. While some people believe astrology out of longing for comfort, so they too, believe in religion or the existence of gravity every time they jump so that one does not fear that whenever one jumps one may drift off into space and thus this does not define astrology as a pseudoscience. If there is anything to speak for astrology as a science it would be that astrology uses the scientific method. The scientific method as developed by many scientists like Einstein as well as well known philosophers such as Kuhn, Popper, Feyerabend and Lakatos consists of observation, hypothesis, experimentation and verification. As astrology focuses on observing the location of the sun and the planets as well as their effect on people, which is the basis of astrological charts and readings it clearly satisfies the first condition. When an astrologist makes a chart of someones birth and makes reading upon that of how their life will be like, that is a hypothesis. The subject living his or her life is the experiment and at the end of their life they can verify whether or not the reading came true. Verification is strongly focused on the results not falsifying the hypothesis but even for lack of that, does an experiment falsifying the hypothesis make it unscientific? High school chemist ry experiments were still science experiments even if the results were not what we expected to them to be. Thus we can say, yes astronomy does follow the scientific method, although through experiments such as one conducted by a French psychologist Michel Gauquelin, where he sent the horoscope of a criminal to roughly 150 people as their horoscope and 94% believed it fit them1, we can see that actual verification may be something difficult to achieve when it comes to astrology, most likely because of how vague and all encompassing the readings prove to be. To some of us, the fact that astrology doesnt make sense in that there are no physical forces in play from planets millions of miles away is enough to declare astrology a pseudoscience. However, as is pointed out by various astrologists, Einsteins theory of curved space seemed absurd until it was proven true and many similarly absurd proposals are still considered science. Philosophers through the ages have also debated (although mostly just agreed) that astronomy is a pseudoscience. One of the most famous demarcations of science is Karl Poppers theory of falsifiability; however astrology cant be classified be a pseudoscience using this. Thagard brought up the points very well in his article Why is astrology a pseudoscience that Popper himself said that no observation ever guarantees falsification because the hypotheses can always be changed and thus falsification can only be a category if a better theory is invented2. Thus although no hypotheses made by astrologists can convince them that astrology doesnt work, astrology can technically be replaced by a modern day Ptolemy- maybe the composition of the planets affect us instead of the gods that rule them or something and thus is falsifiable. Speaking of the gods however, therein lays one of the greatest weak points that show astrology as something that isnt very scientific. Science is the same through all languages, hydrogen is still an atom made of a proton no matter whether its name is in English or Chinese. The planets, named after Greek gods are not the same across languages yet names of things appear to be of the utmost importance to astrologers. Venus who is named after the goddess of love deals with the emotional side of things while Mars is the god of war and thus if youre born under the house of Mars you will be evil,  warlike and contentious because of [your] choleric nature3. Even more worrisome is that the 12 zodiac constellations arose from the Babylonians around the same time the Chinese and Hindus had 28 constellations. Furthermore, the names of the constellations appear to also affect people who are born when theyre in the sky, for example people that are born when the sun is in the quadrant of the sky where Aries the Ram is are supposed be aggressive and assertive like the animal itself. This leads us to the various marks of pseudoscience that D. and M. Radner have set out of which being able to satisfy any one of these conditions is considered to be unscientific4. Anachronistic Thinking Their first demarcation refers to reverting to age old theories that once held fruition in the past. Astrology is a fairly age old theory that was the origins of astronomy whereby in the past astrologers were also astronomers and observed the movements of the planets and the stars. As the correlations of the position of the planets and stars appear to have been passed down from the beginning of astrology from observations made on how the planets affect people from thousands of years B.C., this does seem to apply. Furthermore the moon and the sun are still considered planets in astrology and one would think if Astrology was kept up to date, that someone would have removed them from the equation. In comparison, in order to see the effects of drugs on people we have textbooks which would have new editions every few years to show new findings and remove findings that have been proven false. The main textbook of astrology is still Ptolemys  Tetrabiblos  which was written in 200 AD. In Thagards article Why astrology is a pseudoscience Thagard also proclaims that astrology is uncritical and unprogressive because it never tries to solve unsolved problems like what happens in natural disasters where people with many difference charts, star signs, houses all die in the same way2. Looking for mysteries While astrology does not appear to be deal with mysteries of human experience such as UFOs, there are many mysteries associated with something that is supposed to be scientific. If one were to look up the chemical reaction between hydrogen and oxygen, one would find the same answer from any knowledgeable chemist. If one were to ask 10 different astrologers for their horoscope, one would find many different readings which opens the questions as to which reading is the correct reading. For example a collaboration of studies show that in a group of 559 astrologers when 5- 30 of them are asked to agree or disagree with a given reading of 762 different birth charts, most of them cant even agree that each chart means the same thing. Appeals to Myths Astrology does not actually appeal to myths, instead a quick browse of the Journal of Astrology website would show that it does appeal to old readings that have come true6, namely those made to estimate political outcomes and lives and deaths. However, absent on the site are indication of the numbers or examples of death predictions that have not come true. The grab-bag approach to evidence Astrology does appear to favour large amounts of evidence in that astrologers refer to how many readings in the past have come true (disregarding those that havent) and this method is helped along through the popularity of daily horoscopes in our newspapers whereby every horoscope can most likely correspond to every person. In fact the collaboration of 54 studies that have tested astrologers by giving them charts and telling them to match their owners showed that the average rate of success was the same as if you or I randomly matched them. Irrefutable Hypotheses While astrology is not irrefutable there are many ways and loopholes which allow it to never reach that point. For example, if a reading is wrong a) the person taking the reading could be deluding themselves and really are what the reading says b) the astrologer could have read it wrong c) The person lied about their location of birth and time d) this particular astrologer made it up but the next may make a true reading. The list of possible causes for already vague readings to be wrong that doesnt disprove astrology in any way can go on and on as there is no possible control to be tested (i.e. someone who isnt under the influence of the stars). It is because of the ease at which these wrong hypothesises can be explained and are explained that causes Popper to claim that astrology is irrational and Kuhn to claim it to be astrologys downfall when it comes to being a science as it means their results will never lead to any sort of further research or progression2,7. Argument from spurious similarity A mark of pseudoscience is that the pseudoscientific has a base of principles which are already part of legitimate science. Astrology definitely has a basis in astronomy however there was once a time where astronomy was based on astrology and the star charts and movements of planets used in astrology would coincide with those used in astronomy. Explanation by scenario Astrology uses its own laws to explain different readings and conclusions. For example Uranus is likely a cooling planet due to its modern rulership of Saturns traditional sign Aquarius . These rules and laws most likely originated from original scientific observations of the ecliptic rotations of the planets when it was believed that everything revolved around the earth (seeing as the moon and the sun were classified as planets) and then further built upon with various theories from the Gods they are named after, for example Jupiter is the chief of the gods and thus can rule over other gods. Research of Exegesis Astrologers are selective in their use of scientific research, they do not as many pseudo scientists do, which is to simply take science as statements instead of looking for the reasoning and facts beneath but they do not take into account all scientific research either. For example Michel Gauquelin in an experiment found that there is a greater than chance association of people who are born under Saturns rising or zenith to be scientists and that example may be used by astrologers as a scientific experiment that supports astrology. However, experiments looking at horoscopes of twins born in the same location and at the same time with drastically different futures lay hidden beneath the carpet. Refusal to revise in light of criticism This mark of pseudoscience is something that relates greatly to astrology. Because the Earth is not perfectly spherical, the axis of the earth tilts back and forth in a 26000 year cycles and due to this, the quadrants the constellations occupy in the sky no longer befit with that of when astrology charts were created thousands of years ago. This is called precession and is a problem that astrologers are yet to answer especially since they continue to make predictions as if the constellations still occupy the same part of the sky they use to. Furthermore with the invention of modern day hospitals and caesarean births that causes the time of birth to be different by many hours and sometimes preserves a baby that would have otherwise died, there presents lots of problems with something that is calculated from ones birth time. Apart from fore filling many of the marks of pseudoscience D. and M. Radner have listed, astrology is a topic that has been criticized by many philosophers. Diesing pointed out that astrologers do not collaborate with other scientists like many of the sciences do8, Feyerabend compared it to medieval astronomy whereby it had interesting ideas but they werent developed through any kind of proper research in order to understand how it worked9. Grey in a summarization points out that astrology has a lack of controls and has ill defined concepts that cant be refined and are hard to test10. Most of these philosophers seem to agree that while science is continuously being challenged by anomalies, new theories and results which allow it to progress; astronomy tends to reject these occurrences and thus becomes stagnant. Criticism for astrology does not only stop here even as far back as 44 BC there existed documented criticism against astrology and example of this would be the critique written by Marcus Tullius Cicero who was a Roman statesman. One of his best points was that people do not expect childrens personality or behaviours to be affected by the weather conditions in which they are born and these conditions obviously have by far more effects on a person than dim lights which shine in the sky. He continues that even if children born in the month of December were in some way to be similar how would one know it is not because they were born in cold weather as opposed to the sun rising while a constellation is in the sky11?   This was a very valid point at the time when it was written and thinking along the same lines creates a variety of problems which would be difficult for an astrologist to answer such as why doesnt the amount and gender of people in the immediate vicinity of the baby being born affect the babys personality instead of the stars. Conclusion While it is clear that astrology is a pseudoscience as described by many famous philosophers like Thagard, Kuhn and Feyerabend, I propose that astronomy ought to be classified as something that is not science as opposed to fake science. Because astrology was the origins of astronomy and thus is somewhat intimately connected with science and yet so obviously not scientific, there has been much debate as to its status. However, I would like to point out that it is the scientists who are concerned with the accuracy and effectiveness of the tests conducted on astrology and that, astrologists, while being dismissive of all negative results and findings are really more concerned with the satisfaction of those that seek their wisdom. Rather, astronomy is really more like a religion where people have faith in things that cannot be seen and is rather successful at making people feel connected to society. It provides a way for us to describe ourselves and realize qualities in ourselves and gen erally there are fairly little negative impacts in believing in something like astrology (apart from maybe an unhappy boy who you dont want to date because hes Aquarius). Even better, while it affords the same degree of actual use as a placebo, tests for the accuracy of astrology show as much or as little result as tests for the effectiveness of prayers and instead of having to pay weekly to fund the Church, all you have to do is get your chart made once and from then on, are able to blame the stars for your failings. As Leahey and Leahey said, astrology provides a means for pursuit of happiness and is in a way like a cheap method of psychology where you can discover yourself while letting the stars take the blame for any bad attributes you have and yet be comforted at the same time since there is no God to judge you at the end.

Principles of Transportation Economics

All through the phase of airline regulation, the government set airline faires and regulated an air carrier's entry into and exit from particular markets. Assuming that the incumbent airlines made economic profits while they were regulated, what impact, if any, did the government's regulation of routes have upon air carrier's ability to make profits?Transportation economics is considered as the analysis of the share of carrying wherewithals so as to come across the necessities of the general public (Encyclopà ¦dia Britannica Online, 2007). In a broader sense, delivery pursuits create a segment of a state’s entire trade and industry items for consumption and take part in the responsibility of constructing or intensification of a countrywide or local economy and as a stimulus in the progress of assets.With the hauling precautions direction, there is a constraint that the travelers must hand over a boarding documentation ahead of going through zones outside safekeeping checkpoin ts. Numerous airlines recently proffer passengers the means of departing through the net and producing lodging permits or licenses prior to leaving.Due to government intervention, the imposition of government faires will consequentially affect the fees of airline carriers’ consumers. They will be compelled of taxes, charges, and additional costs on matters such as fuel, airport rents, aircraft financing, which will be reflective and increase the prices that they will be paying for (Hardisty, 2003). And therefore, will have a lower demand for the airline services.This may indeed affect the income of the incumbent airlines since their transactions are regulated. Consumers of their service will eventually hold back their use of the airline service since there are a lot of barriers to entry as stated by Palmby (1995). The former ease of access was lessened. For these reason, people will not be able to bring some things that they usually carry or transport.Additionally as discusse d by the Federal Aviation Administration (FAA) and Optimal Solutions and Technologies (OST) in 1999, on account of the government intervention, the administration of airline carriers will have fewer opportunities to improve their systems and just depend on the established government regulation of airlines. Significant losses can be incurred by the managing airlines and they tend to stay extremely susceptible to drop in airline interchange. Their pecuniary chances have gone through noteworthy stumbling blocks.However, although the government regulation of routes has a negative impact upon the air carrier’s ability to make profits, it has also a positive impact in return.Some terrorist attacks through air carriers may be prevented, hence, the management of air carriers does not have to spend money on possible damages that terrorism may have caused (Potter, 2006). Aside from that, together with the cooperation that the management of air carriers is receiving from the government, the running institution may have a directory or catalog of legal persons who may possibly avail of their services. Therefore, the management of air carriers does not have to spend their resources on tracking some unauthorized and illegal passengers. Furthermore, because of authority supervision, there will be more convenient gate assignments (and less reassignments); as a result, more people may eventually avail of the airline services despite higher costs of transport. These sets of incidences cyclically may contribute to beneficial return of earnings to the airline managements.Even though there is a prevailing acquisition and implementation of government regulation in airline carriers, with proper and appropriate administration of their managements, they will be more likely to have a good return in the running government regulation or will be able to have better accumulation of profits.References:FAA/OST Task Force Study (1999).

Monsanto Expansion

Monsanto expansion Monsanto Corporation was discovered in SST. Louis Missouri in 1901. The Monsanto Chemical Company was built for its business of selling food additives such as saccharin and caffeine. During the past ten years or so, Monsanto had merged its chemicals business to focus on biotechnology. By using whole systems of herbicides, pesticides and genetically engineered seeds designed to flourish In an environment swamped with chemicals, Monsanto promised to help farmers nourish the world more resourcefully.Monsanto, well known for its lies and soiled dealing in pesticides, was founded Just to remote saccharin in 1901 which led to further dishonestly. What was its main customer at the time? A drink company named Coca-Cola. Approximately 60 percent of food produced in the United States has pesticides. Monsanto Indeed had been changing the genes of these foods. Monsanto started producing EDT In 1944. Rachel Carbon's Silent Spring talked about how pesticides were bad for our env ironment. In many cases she is right. Pesticides are harmful to every part of life. When pesticides enter a body it will never leave, the body cannot break it down.The Monsanto Company made up their own version called â€Å"The desolate year. This story shows the effects if there were no pesticides and no way to terminate Insects. This story Is about Insects over-running a world lacking pesticide poisons. Another book called â€Å"Desolate Spring† that showed an America land waste not by pesticides but by insects: â€Å"The bugs were everywhere. Rachel Carson could not respond because of cancer tumors in her cervical vertebrae. This caused loss of function In her right writing hand, than her death 18 months later from breast cancer. When Rachel Carbon's Silent Spring was published in 1963Monsanto biotech seeds and traits accounted for almost 90 percent of the total world area. It was devoted to Genetically Modified seeds by 2007. Today, over 80 percent of the worldwide regi on Is devoted to Genetically Modifying crops carrying at least one genetic trait for herbicide tolerance. Herbicides account for about one-third of the global pesticide market. Monsanto glasshouse-resistant are â€Å"Roundup Ready seeds that have reigned extreme on the biotech scene for over a decade. Roundup is the world's biggest selling pesticides and it has helped make Monsanto the world's fifth largest agrochemical corporation. Whiteners and food additives, pharmaceuticals, industrial materials and agricultural chemicals. The company's history was mainly in the chemicals industry. Having started in 1901 as a manufacturer of saccharin; by the sass's Monsanto was involved in businesses with oil/gas exploration, the production of acetic acid, plastics, synthetic rubber, resins, polystyrene, polyethylene, insulation, flame retardant materials, and Astronaut. In 1978, agriculture and food processing together accounted for Just 17 per cent of the company's sales. Nowadays, Monsanto is one of the world's largest seed companies.Although it remains the manufacturer of the world's best selling herbicide brand and roundup; it has shed its industrial and specialty chemicals divisions. The sweeteners business and even the pharmaceutical subsidiary which it acquired in 1985 is now an agricultural business that focuses on herbicides and seeds and is 2 completely head of the global market for genetically modified crop traits. The major elements of this dramatic transformation in the company's profile occurred in only about ten years between the early sass's and the early sass's.The effects that these pesticides Monsanto began making became hazardous to all existing creatures. When making â€Å"2, 3, 5 -T† in the late sass's, its workers developed skin irritations, Joint/limb pain, weakness, petulance, nervousness and loss of libido. It also caused Cancer and liver disorders. As obstetricians in Vietnam are aware, horrible fetal deformities have also been strongly linked to the tainted herbicide. In 1944, being one of fifteen companies licensed to do so, Monsanto began manufacturing EDT. EDT is a synthetic pesticide used for agriculture; to help rid of insects and help aid disease control.EDT was exiled after the â€Å"Environmental Protection Agency' found out these chemicals were going to be toxic to society. Monsanto was also one of very few companies to produce the defoliant â€Å"Agent Orange† during the Vietnam War causing over 900,000 deaths, disabilities and birth defects. In total, over 4. 8 million Vietnamese were exposed to this highly lethal chemical, as well as 20 percent of the Southern Vietnamese Jungle over nine years. The introduction of Genetically Modified crops has been promoted by three impasses Monsanto, Agents, and Brayer.These businesses are responsible for virtually all of the commercially released â€Å"Genetically Modified† crops in the world today. Now Monsanto 3 selling â€Å"Roundup-Ready' soybea ns, canola and corn seeds, which are produce plants that can stand high doses of Monsanto herbicide Roundup. Recently Monsanto has obtained several seed companies including â€Å"Holder's Foundation Seeds†, â€Å"Grows',† Agronomics†,† Deckle Genetics†, â€Å"Delta and Pine Land† and â€Å"Segments Grocer's†. In effect Monsanto is controlling the grain market. Its genetic engineered, herbicide resistant seed could become the only choice for farmers.In addition Monsanto merger with American Home Products creates the biggest manufacturer of pesticides and herbicides in the planet. If Monsanto dominates both the grain and pesticide market there is no way anyone will be able to contend with them. There are four crops that have been the primary source of genetically modification. These crops are soybeans, maize, cotton and canola. In the world marketplace these crops have turn out to be pretty noteworthy. According to industry sources; soybea ns, size, cotton and canola constitute 99 percent of the world's acreage of GM crops.With soybeans alone covering 60 percent of the total planted area, it was estimated that 56 percent of the soybeans being farmed were genetically modified. Cotton was 28 percent genetically modified and Maize 19 percent. Today, most of these GM crops are concentrated in a few countries. During the first seven years of nurturing in 1996 and 2002 only three countries the United States, Argentina and Canada were in counted for. In 2004, more than 84 percent of â€Å"Genetically Modified† crops were still encountered in these same three countries.
