Circulatory System Essay Example for Free

Circulatory System Essay His first point criticised Paley’s analogy of the watch. The first part of the analogy claimed that if you found a rock while walking through a heath, you would not think anything of it. However, if you had seen a watch you would examine it and find that it had moving parts that demonstrate that the watch has a purpose, the parts work together for a purpose and they are ordered to make the watch function because if they weren’t, the watch won’t perform its function. He concluded the first part of his analogy by saying that the watch had a maker who must have existed at some time and place. The second part of the analogy claimed that if we suppose the watch had another imaginary function, and this function was the producing of other watches, then our admiration for the watchmaker would be increased. He concluded this part of his argument by saying that anyone who finds such a watch would conclude that the design of the watch implies ‘the presence of intelligence and mind’. Paley said that just like the watch being designed necessitates a designer as an explanation of its existence, all of nature requires a much greater designer. The complexity of nature is far greater than any machine human beings can make and therefore a grand designer is needed, this designer is God. Hume criticised this point by saying that the analogy is limited. For example, you could conclude from a study of the human blood circulatory system that animals had the same system. This would be a weak and mistaken analogy however to compare a human’s and an animal’s circulato ry system to the way sap circulates in a plant. Hume maintained his criticism of Paley’s analogy of the watch by an analogy of his own. This analogy said that we can conclude that a house had a builder and an architect but we cannot, however, deduce a builder or architect of the universe in the same way because there is no similarity between the two. He mentioned that if the house is faulty, what does this suggest about the designer? And so, if God did design the world, is he directly responsible for the evil within it? Paley, however, rejected this point because the issue was whether the universe exhibited signs of design. He was not concerned with questions relating to issues of quality concerning the design. Paley’s response was criticised to be unsatisfactory. Hume argued that there are other possible explanations than God for apparent design in the universe. Hume claimed that one of these possible explanations might be that as well as the possibility that there is a grand designer of the universe, it is equally possible that ‘matter may contain the spring of order originally within itself, as well as mind does’ and that unless there is perfect similarity between the object of comparison and what is being compared, you cannot draw a conclusion with any certainty. Another possible explanation for apparent design in the universe might be that any effects that we observe in nature may be caused by a variety of causes. This view supports the discovery of natural selection and the DNA and its role of shaping the growth of all living organisms. Hume claimed that there might not be just one single designer for the world. For example, we may look at a great ship and think about the great design of it, but the ship may be the result of years, even generations of trial and error. The ship may be the product of many hands and not just one great designer. From this, Hume concludes that there is no evidence to suggest the ‘unity of the deity’. Hume suggested three more theories as explanations for the design of the universe; aptness of analogy, the epicurean thesis and the argument from effect to cause. The aptness of analogy said that a watch is not a suitable analogy for the world. For example, just because a cabbage is fitted together/designed perfectly, does not mean that it has a maker/designer. By using a machine as an analogy, you would have already determined the outcome you want; you want there to be a designer and you’re already assuming that something natural, i.e. the cabbage, has a designer. The epicurean thesis was explained using an example. This example spoke about particles and said that if they were freely moving around over infinite time, by chance, one of the combinations they make would just happen to represent a stable order and this stable order is what we now live in. This example represented the view that the universe might have happened by chance. The argument from effect to cause claimed that we cannot go from an effect to a greater cause than that needed to produce the cause. We cannot say whether he made the watch alone or had some little helpers. This would mean that we do not and cannot know whether he is still active or even still alive, we can only say if the universe does/doesn’t have a designer and can’t list its traits by saying that he is benevolent, omnipotent, omniscient and infinite as many would portray him. Overall, Hume criticises the teleological argument in a number of ways. He very explicitly criticises Paley’s views on the teleological argument, using them to explain why he believes that the argument is deeply flawed.

Televised Executions Essay -- Ethical Issues, Death Penalty

In recent years, more and more people have become aware of crime and murder. It is something that has affected them, their families and neighborhoods. Just about everyone in the world knows someone who has become a victim of murder, rape, and or robbery. In most cases the suspects are heartless and have no remorse in regards to the crime they committed. Some individuals are repeat offenders who have received a slap on the wrist from the justice system or only faced small jail time. A recent report by the Senate judiciary Committee, called America the "most violent and self-destructive nation on earth", and it was noted that violent crime in America had increased by 516% since 1960 (Economist, 1992). Many individuals have tried to come up with solutions and scare tactics attempting to deter those who commit crime. It appears that solutions are failing. One author has his own theory of deterrence. George Bryjak the author of â€Å"Why we should all watch Executions† believes that if the justice system televised executions to the public, this would deter individuals from committing crimes. Bryjak stresses his point saying: â€Å"deterrence relies on theory that people will refrain from participating in homicide or crime if they perceive the threat of swift and certain punishment, the death penalty could be made a more effective deterrent if executions were televised and reached a larger audience on a regular basis† (Bryjak, 2001). Bryjak appeals to readers in a serious tone and makes very valid points for his reasoning. Bryjak’s thus fails to provide sufficient evidence on some of his reasoning to convince readers on his position. In the article, Bryjak reaches the heart of his readers by reminding them of the man wh... ...e author doesn’t convince readers by simply saying â€Å"executions should be public spectacles† that this would deter crime. The author even presents credible evidence from those who oppose; Bryjak even agrees they make his position look bad. The author doesn’t refute that people are going to commit crimes regardless if they watch someone get executed or not. Research shows individuals are threatened everyday with the consequences they can face for disobeying the law, yet there still appears to be an increase in crime and violence. Many that commit crimes are aware of the possibility of receiving the death penalty if sentenced, however many individuals still continue to commit acts of murder. The article is entitled â€Å"Why we all should watch executions† and I don’t think Bryjak persuaded readers on why they should watch but more so on why there should be executions.

Airport Security: the Post 9/11 Age

Airport Security: The Post 9/11 Age Airport security in the world we live in today is drastically different then the security we knew before the events of September 11, 2001, when four passenger airliners were high-jacked over the skies of the United States, causing a global terror pandemic that still has long lasting effects today. We will look at, discuss and break down some of the key features of airport security in Canada as well as the United States, that have been improved, as well as certain security programs and features which were freshly implemented as a direct result.We will discuss â€Å"no-fly lists,† personnel training and armament, and the Canadian Air Transport Security Authority or â€Å"CATSA,† including their security screening techniques and procedures (screening, responsibilities, Air Marshalls). The â€Å"No-Fly List† was created shortly after the events of 9/11, by the United States government’s Terrorist Screening Center (TSC). The list includes the names of people who are deemed unsafe, or a threat to Airline security and are no longer permitted to board a commercial airline for the purpose of travel coming in or out of the United States.The list now contains roughly 10,000 names (2011), the number people on the list fluctuates based on threat, and intelligence reporting. Canada also has a similar list called the â€Å"Passenger Protect,† a similar initiative to that of the United States list, implemented on June 18, 2007 in order to identify people who could be a threat to the security of aviation, and prevent them from boarding Canadian domestic flights as well as International flights to or from Canada.The Passenger Protect program has two main parts: a set of â€Å"Identity Screening Regulations† which requires all passengers 18 years of age and older to present a valid form of government-issued Identification in order to board a flight, as well as a â€Å"Specified Persons List† whic h has a name, birth date, and gender of the individuals believed to pose a security threat. The list contains roughly 1,250 names. Individuals who have been denied boarding and are in fact on the list can submit an appeal to a branch of Transport Canada, called the Office of Reconsideration.The program works by the government supplying the Specified Persons List to Airlines, who then compare names of people on the list with individuals who intend on boarding flights. When the airline finds a name match, they then reference the individual’s government-issued identification to confirm. The identification is then once more confirmed in person at the airport check-in area, when a confirmation has been established Transport Canada is immediately notified.Training is also provided by Transport Canada to the airlines to teach staff and agents how to implement the ID verification process, and establish procedures to ensure the rights of the passengers are respected. Of course with a system like this, controversy is brought up by civil liberty organizations citing their concerns for civil liberties, racial profiling, privacy, and the perceived failure of the no-fly list created in the United States. In the United States, several anomalies’ referred to as â€Å"false positives† have risen.A â€Å"false positive† happens when an individual who is actually not on the no-fly list, has a name matching or similar to a name on the list. One notable case of a false positive includes a United States Marine in April of 2006, who was flying home from Iraq when he was prohibited from boarding his flight home, as his name matched one on the no-fly list. The lists, although very controversial both here in Canada and in the United States play an important role in establishing airport/airline safety and security, and ensuring an event such as the attacks on September 11, 2001 will not re-occur.Secondly, the way Security Personnel are trained and armed has b een drastically affected in the post 9/11 world. In the United States, immediately after the attacks for several weeks to months afterwards, fully armed guards, either Local Police or National Guard would patrol airports in full tactical gear wielding assault rifles or tactical shotguns. In Canada the response was similar, however not as fully extended as in the United States.In Canada today, the Canadian Air Transport Security Authority (CATSA) which is thoroughly explained in the next topic, handles all screening procedures by hiring third party private security firms to conduct screening. Our general airport security providing safety is executed by local Police forces. The RCMP once used to handle all general airport security, now only handles a few airports including Edmonton International Airport. Edmonton International Airport has a detachment of the RCMP located on site to ensure a quick and proper response to emergencies, ecurity and policing needs. The Police members on sit e are trained in emergency preparedness in order to be able to respond to a wide range of situations, including terrorism attacks. In addition to human Police officers, many airports such as Edmonton’s, implement canine members for certain situations such as sniffing out drugs, weapons, people, and explosives. In Edmonton specifically, at the RCMP airport detachment, they have Badge, a German Sheppard trained in attacking criminals, searching for lost people or baggage, as well as the ability to sniff out 15 different explosives.As well as the main goal of airport security of keeping a safe and problem free environment, security also includes Emergency Response Services (ERS). Fire and medical services are always ready at a moment’s notice 24 hours a day, 365 days a year for emergencies such as fires, aircraft mayday emergencies, and terrorist attacks. The Emergency Response Services are always highly trained and outfitted with top of the line vehicles and equipment to deal with any situation, and all have requirements and policies on stringent response times.An example of the preparedness by the ERS in Edmonton is their ability to make it from the fire hall located on site to the mid-point on the furthest runway in 3 minutes. Finally, as a direct result of the attacks of September 11, 2001 we seen the formation of the Canadian Air Transport Security Authority or â€Å"CATSA,† in December 2001, introduced by then Finance Minister Paul Martin, which included a very comprehensive plan aimed at enhancing economic and personal security in Canada.In April of 2002 CATSA took over responsibility of passenger and employee screening, although they still hire private security companies to do much of the screening, CATSA still oversees training and equipment available. CATSA states their mission is â€Å"to protect the public by securing critical elements of the air transportation system†¦ † Their responsibilities can be grouped into four major areas; Pre-board screening, hold baggage screening, non-passenger screening, and Restricted Area Identity Cards.Pre-board screening is done by Private Security firms hired and governed by CATSA, their tasks include getting all carry-on items coming onto an aircraft to go through X-ray, individuals must then pass through metal detectors and physical searches can and will be executed if an alarm is raised either through the metal detector, or random selection. Full body scanners are also used to reveal weapons, objects or explosives hidden under or within clothing. CATSA also implements the use of Explosive Detection Trace (EDT) technology at security checkpoints; this involves a quick swabbing of carry-on items or hands to test for explosives.Hold-Baggage Screening (HBS) is another major area of CATSA, this is what happens to our baggage once it has been checked in and is on its way to be loaded onto the aircraft. This is the process of screening all checked baggage using a co mbination of state-of-the-art explosive detection technology, as well as highly trained security personnel. During HBS the density of baggage is tested as well as additional testing for trace amounts of chemicals. HBS is currently in full deployment in 89 airports across Canada since 2006, for all domestic and international flights.CATSA is responsible for the instillation, deployment and renovations of HBS systems as well as regulatory compliance monitoring. Another major area of CATSA is non-passenger screening (NPS), this is required by Transport Canada starting back in 2004 and involves the random screening of people who work at the airports, these people can include flight crews, airport crews, caterers, maintenance workers, and baggage handlers. This subjects employees to unpredictable security screenings at entry points within airport restricted areas, the screening process is similar to that of the passenger screening, and also includes an Identification check.CATSA states t hat they screen 2,500 employees a day out of the 100,000 employees who have access to secure areas in Canadian airports. They also state that this program is continually evolving, as the only constant is â€Å"the cooperation needed between screening officers and non-passengers. † The fourth noted area of CATSA is the Restricted Area Identity Card (RAIC) program, which is constantly advancing through the use of biometric scanners. The RAIC program uses state-of-the-art duel biometric scanner identification programs to ensure the identity of the personnel who have restricted access.The program includes cards with built-in microchips to store biometric information of fingerprint and iris scanner templates. The RAIC program has been fully functional since January 31, 2007 in over 28 major airports in Canada. It’s notable that the biometric technology used here is also utilized in non-passenger screening and these two programs work in conjunction with one another. CATSA al so jointly implements the Canadian Air Carrier Protective Program (CACPP) with Transport Canada; this program is similar to that of the U.S. Sky Marshall Program. This program strategically places highly trained, armed, undercover RCMP members, also known as In-Flight Security Officers (IFSOs), on Canadian registered commercial airliners. IFSOs mandate is to be able to successfully prevent the aircraft from being taken over by an unauthorized individual(s), as well as gather and interpret intelligence on terrorist and criminal activity within civil aviation. In conclusion, airport security in North America and the world will continue to grow and prosper.In the post 9/11 world today, policies and procedures will only grow tighter and more stringent in an effort to prevent terrorism. From no-fly lists created to prevent the wrong people from boarding passenger planes, to tighter and better trained local Police and Security personnel on the front lines preforming screening, security an d emergency response services. To government initiatives like the Canadian Air Transport Security Authority providing important and well-rounded security systems from x-ray scanners to In-Flight Security Officers, the airline industry has never been more stringent in counter terrorism.References Airport screening: 9/11 response.

Glacier and Citrus College Chapter Essay - 4631 Words

ESCI 118 – Physical Geography Citrus College Chapter 17 – Solution Processes and Karst Topography 1. How does carbonic acid form? It forms when water and carbon dioxide combine and react. 2. What is meant by dissolution? Dissolution is the action of being dissolved. 3. What kinds of rock are most susceptible to solution processes? Why? Limestone and dolomite are most susceptible to solution processes because the water, which is slightly acidic, reacts with rock and dissolves the co2 gas carrying away or dissolving some of the sediment. 4. How does the underground structure of the bedrock influence the dissolution process? Bedrock that is made of carbonate is more†¦show more content†¦In an arid land, there is less precipitation than the potential evaporation which is not the case in humid regions. 2. What is meant by an impermeable surface and how does such a surface influence the results of rainfall in a desert? An impermeable surface cannot be penetrated by any element. Such a surface will not allow rain to percolate into the desert soil leaving no plants with root systems able to survive unless specifically adapted to the climate. 3. What is a basin of interior drainage? The land is uplifted crust blocks that form parallel ranges but surface water doesn’t run to the ocean. Instead, it evaporates over time leaving a salt flat. 4. What is the difference between an ephemeral stream and an exotic stream in a desert? An ephemeral stream is a stream that only exists during rainfall. Exotic streams come from an origin outside of the desert. 5. Although there is very little rainfall in deserts, running water is still the most important process of erosion and deposition in arid environments. Describe and explain at least two special conditions in deserts that tend to increase the likelihood of fluvial erosion whenever it does rain. Any rainfall increases fluvial erosion. When rain does fall, this creates ephemeral streams causing water erosion due to fast forces of water. Flash floods are possible as well creating even more erosion. 6.
