Euthanasia - Essay Example This paper analyses, critically, the arguments for and against Euthanasia. In the conclusion, I have given a personal opinion on my view of Euthanasia. The following are the main pros and cons of Euthanasia. One of the main arguments advanced in support of Euthanasia is the argument that Euthanasia is a morally right action because human beings have a right to self-determination, and for that reason, they should be allowed to choose their own fate (ProCon.org, n.d.). The proponents of Euthanasia contend that since human beings have the right to self-determination, denying euthanasia to the terminally sick patients who need and request for it is immoral and a violation of their right to self-determination. In law the issue of self-determination in regard to Euthanasia is a controversial issue, especially in the United States. Various courts in the United States have interpreted this issue differently. The following case demonstrates how the issue of self-determination in the United States constitution is a controversial issue. Year 1975, the 21 year old Karen Ann Quinlan was admitted in a hospital in a comma. The doctors at the hospital later declared Quinlan to be in a persistent vegetative state. After spending five months on a ventilator, Quinlan’s parents requested that the ventilator be removed and that Quinlan be allowed to die peacefully. The doctors at the hospital, however, objected to Quinlan parents’ requests, and this made the parents to bring the matter to a New Jersey Superior Court. In the ruling, to the disappointment of Quinlan’s parents, the New Jersey Superior Court denied the request of Quinlan’s parents. When Quinlan’s parents, however, took the matter to the New Jersey Supreme court, the Supreme Court reversed the ruling of the Superior Court and ruled that Quinlan’s constitutional right to privacy included her right to be removed from the

The Father-Daughter relationship of Atticus to Scout Essay Example for Free

The Father-Daughter relationship of Atticus to Scout Essay The relationship between a father and a daughter is something that has been cherished throughout the ages. Each plays a large role in the development and growth of in each others lives and personalities. The same is true for the relationship between Atticus and Scout in the novel To Kill a Mocking Bird. The stereotypical father to a daughter is usually large, protective, and very kind. Atticus, however, does not fit the stereotype. He is kind, but unlike most fathers, he is tall and skinny, and just tends to read all day. Atticus does not fill the stereotype; however he is a father that parents his daughter with values and tolerance. He does play a role of father figure, but Atticus seems to be less of a father and more of a teacher in Scouts life. The way he instructs her about life, and about how to deal with people, it seems Atticus is attempting to be a teacher to Scout. Atticus, in his wisdom and age, understands Scout very well, if not too well. We see Atticus as being almost omniscient in Scout, and Jems lives. He is the rock and ever unchanging constant factor in their life and his influence is very heavy. Scout is almost a challenge to Atticus, as to how to rear his child to the best of his ability to shape her for the best of circumstances. Though he is her father, Atticus is a teacher and a mentor. His influence affects a lot of Scouts decisions, and Scout helps teach him about life as well. Scout, being a young developing girl, has many changing aspects and thought processes. She tends to be unreliable, and ever-changing, and not at a slow pace either. Scout shows Atticus that kids dont yet know the basics; they need to be taught from the beginning, and need to learn quite a bit about etiquette and how to deal with other human beings. Her relationship with Atticus tends to be mostly that of a pupil to a teacher, but sometimes shifts slightly. In some instances, she fills the role of Atticus daughter, and acts upon love as if related, rather than reason. For sure, Scout knows that she loves Atticus, and she knows he is her father and she respects him. She just does not always treat him like a father, and when she doesnt, she is his pupil. Scout has limited knowledge because of her age, and thusly, cannot understand Atticus as well as he understands her. Atticus tends to be  an enigma to Scout, and reveals himself only when she asks questions, but not revealing himself all the way. She does not understand him in a way a daughter gets a father, but she does have the general knowledge of understand of how a student understands a master. This just furthers the point of their distant relationship. Thought Scout does not understand Atticus as Atticus does Scout, they still have a profound relationship that is almost air tight. The sacred bond between daughter in father comes in many varieties and fashions, one of which being Teacher and Student. This happens to be the way that Atticus and Scout are, which does mean that they arent as close as others. Scout is still developing in life, and her role in Atticus life is changing, and eventually will take on an entirely different form. But as of now, Atticus tends to be the understanding teacher, while Scout is the ignorant pupil. Sources: To Kill a Mockingbird, by Harper Lee

6lowpan Neighbor Discovery Protocol Computer Science Essay

6lowpan Neighbor Discovery Protocol Computer Science Essay The IPv6 over IEEE 802.15.4 has specified way how to carry IPv6 packets over IEEE 802.15.4 standardized devices and similar networks with the introduction of an adaptation header which comes before the IP header and just after MAC layer, a link in such a 6LoWPAN is characterized as lossy, with minimum power consumption, minimum data rate, small range, with many nodes saving energy with hibernating or deep sleep schedules. IEEE standards are based on low memory devices which has a limited MTU size keeping this under consideration we have to see how we can fit IPv6 address in that limited space we have and even UDP packets also which are used in our transmission. IPv6 already posses a big memory but in use of 6LoWPAN all the headers are compressed with special compression algorithm so that they can be fit in the limited space of IEEE standardized MTU. Compressing algorithm are bit different according to the use or according to the network topology, as 6LoWPAN support both ad hoc and st ar technically used as Mesh Under and Route Over. | Application Layer | | Transport Layer (TCP/UDP) | +-+ | Network ++ | | Layer | Routing | | | (IPv6) ++ | +-+ | 6LoWPAN Adaptation Layer | +-+ | IEEE 802.15.4 (MAC) | +-+ | IEEE 802.15.4 (PHY) | +-+ Figure X: New adaption layer introduces IEEE 802.15.4 has some several types of frames like beacon frames, MAC command frames, acknowledge frames and off course data frames also, IEEE standardize addressing mode also which are further described in this documents these are 2 basic i.e. 16-bit short addresses or a unique identifier and 64-bit unique addresses. A particular LoWPAN header will be like this after compressed field containing all the field like IEEE header Mesh header or if Route over is used depending on the network topology used then fragment header and in the end IPv6 compressed header. Figure X: Typical LoWPAN Header Stack Several compression methods are used or developed to keep the header compressed and fitted in limited amount of space and should be working according to the desired need, compression algorithm like gzip, deflate, ROHC but normally and best fit for this scenarios are the HC1 or HC2 compression header formats. They are predefined formats having their own formatting to represent data and data types [9]. This can best describe us how the header look like after all there field filled and necessary information saved for transmitting the packet from node to other may be in the LoWPAN or may be on other LoWPAN, this is only the structure defined and use by the LoWPAN nodes. Now we can consider a node which wanted to join a network and what necessary things will be needed and what processes it has to go through to final get his IPv6 address, as IPv6 has some standard predefined for normal Ethernet use like multicast as used in classic IPv6 Neighbor Discovery is not useable and desirable in such a wireless low-power, lossy network. Network discovery is just a simple procedure as defined in classical IPv6 to get the fresh node bind with the network. 6LoWPAN Neighbor Discovery (6LoWPAN-ND) is specially designed for LoWPAN networks which provides some basic operations of bootstrapping and other simple network operation, even they some advanced features includes claim and defends address generation and Extended LoWPAN over backbone links, while avoiding the flooding from multicast; this solution supports the use of both link-layer and LoWPAN-level Mesh Under and Route Over solutions. 6LoWPAN-ND design introduces a registration method over the radio edge of the network and proxy operation over the federating backhaul, this registration mechanism provides a examination similar to the Multicast Address Resolution Server (MARS) for a restricted purpose, and in a much simpler and generic way for those link scope multicasts is unavoidable, such as for Router Advertisements, optimizations may be used to optimize the distribution of the information in the LoWPAN. The new concept behind LoWPAN Whiteboard located at Edge Routers (ERs) is introduced which works as the cache to maintain he entries from the registration of nodes, which allows for Duplicate Address Detection for the entire LoWPAN. A new registration/confirmation message sequence is specified so that nodes can register themselves with their IPv6 addresses with an Edge Router. These white boards are the cache of edge routers contain all the information regarding the nodes which are registered with the LoWPAN wit h their unique IPv6 address and network prefixes. The Whiteboard uses soft bindings of nodes meaning the entries will be expires until particular time if not getting updates from nodes before the life time of registration of the nodes expires, thus nodes can send periodic registration messages in order to update their bindings with the edge routers and to keep the cache record updated which node was last updated and registered to which LoWPAN router range, changes in network topology and mobility between ERs and LoWPAN are supported and sometimes unreachability of routers can be detected in this way. This research also put an eye on the combination of an Extended LoWPAN with more than one edge router working in same LoWPAN sharing same backbone link (e.g. Ethernet) getting advantage of having a single IPv6 subnet. This allows nodes to keep the same IPv6 address throughout a large network if they move from the domain of one edge router to other and registers them with a new edge router which allows for easy communications and even ro uting among the same LoWPAN is easy with nodes over the backbone link and with other IPv6 hosts. Edge Routers backed by Ethernet link working on an edge of LoWPAN networks in this particular scenario one edge router will be maintaining or working as DHCPv6 server and other routers in his domain will be working as relaying router. A LoWPAN network typically uses two types of Layer 2 addresses à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ for example 16-bit short addresses or a unique identifier and 64-bit unique addresses. Additionally, the available Layer 2 payload size with respect to payload we might need to use header compression as explained earlier and use a minimum payload on the order of less than 100 bytes. These network is lossy and battery-powered, and it does not support multicast capability at the link-layer, thus pretending multicast actions by both using broadcast or sending a number of unicast messages which are costly for the battery powered network and the low-processing capable nodes. Often these battery-powered nodes save energy by using sleep schedules and keeping themselves in sleep mode to save battery power; waking them up just to receive IPv6 signaling messages so that they can only be updated in our oneà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s domain only is not useful on this case what nodes usually programmed as they will get themselves updated and the registration has a life time and if the node did not update himself before that the entry in the white board will be discarded, these nodes do schedule there sleep time but keeping the timer of registration a little longer then there sleeping time so usually they wake up before the cache entry expires, also they are not competent of processing RA for their neighbors efficiently. Sometimes due to the strong radio signal from a neighbor router or its own strength, a node may often move from one network to other network from one router to another without physically moving. Considering the above characteristics in a LoWPAN, and the IPv6 Neighbor Discovery basic requirement of his protocol, it was finalized that class ic ND protocol of IPv6 is not good to be used in LoWPAN so a little different protocol for LoWPAN has been designed as 6LoWPAN-specific ND. 4.1 6LoWPAN Neighbor Discovery Protocol Overview 6LoWPAN Neighbor Discovery optimizes with a mechanism which is on its own least yet very important for LoWPAN IPv6 operation. 6LoWPAN-ND defines a registration process which optimizing the node-router interface, this mechanism do not work on flooding which reduces link-local multicast frequency. 6LoWPAN-ND can work with non-transitive links also, the use of mesh-under and route-over techniques and makes no hypothesis about node synchronization. 6LoWPAN-ND is compatible so that they will be used with the link-layer mesh techniques, which improve the if not non-transitive characteristic nature of wireless links if they are used throughout the LoWPAN, this normally called Mesh Under topology which make the whole link IP layer as having a link-local scope making all the 6LoWPAN interfaces in the LoWPAN. This kind of LoWPAN is consisting of hosts and Edge Routers, this link still lossy, slow data rate, irregular behavior along with sleep mode. The non-transitive nature of the link can be overcome simply by using routing based on IP with in single domain of a LoWPAN, also called a Route over topology. Routing between all nodes in the LoWPAN is done by LoWPAN Routers in the LoWPAN. Mesh Under and Route Over techniques are not limited. 4.1.1 Bootstrapping A Host performs independent address auto configuration of its link-local unique and single t address for each LoWPAN interface from its EUI-64. The process of joining a LoWPAN is done either by listening of RA or either by sending a broadcast message of Router Solicitation (RS) and in return it will receive RA an acknowledgement message responses from local routers, there may be more than one router it a particular range. It mainly depending if a true prefix is advertised in the RA, the host will also form a positive global unique address with auto configuration, this is the point the node can choose more than onr router if its available to get himself registered its only if it have signals from more than one LoWPAN. After selecting the desired router the node will make some effort to first perform node registration and get itself bind with a router, registration is performed with a link-local Edge Router or LoWPAN Router by sending a unicast Node Registration (NR) message to it from host to router. It is more good to get yourself registered directly with an Edge Router, although all other routers with in a LoWPAN has capability to work as a relaying agent on the LoWPAN have the capability to relay NR/NC messages on behalf of a node. The NR contains the addresses of the node who wants to register. A node may also request a short address of 16 bit to be generated on its behalf when the Edge Router get a request of NR its replies either directly with a Node Confirmation (NC) message to the host or through the help of relaying router which is in between node and edge router, relaying routers only exist in Route Over configurations or network topology and in pure Mesh Under network topology and scena rio, configurations nodes are within link-local scope or range of an Edge Router. This NC message includes the set of unique addresses which will be updated and also made an entry in the Whiteboard and address will be bound to the ER the Host is now registered and can use the LoWPAN. 4.1.2 Basic operation The node is now ready to use and may send packets to any IPv6 address inside or outside the LoWPAN or over the internet every request for Next-hop will be sent to the predefined default router but only local address which will redirected to as they are present in local domain. The white board entries and binding table of LoWPAN Router must be renewed on every pre defined intervals as per advertised interval and the lifetime of the binding, the white board entry will be valid in till it expires and then the current entry will deleted from the routers cache. This is achieved by occasionally sending a new NR message when ever host changes his location from original LoWPAN to another LoWPAN or may be some change in network topology occurs or may be some certain router is no longer in reach then host have to get them registered again with the nearest available route. Host then starts the registration process with another router if the LoWPAN does not change for host its IPv6 addresses rem ain the same. Addresses bound or the entry in the Whiteboard must be remembered by the host and updated in order to keep the address. If the host moves to a different LoWPAN, the bootstrapping process is initiated again the host may be moved while he is sleeping mode. LoWPAN Routers at times send RAs to their neighbors in order to keep themselves and their neighbors updated. The Edge Router triggered the first RAs, and information from these RAs is included in the RAs of each further router where this RA travel, causing the information to be spread throughout the LoWPAN and to every router on it. 4.2 Address collision detection and resolution The address collision process can be carried out within the Edge Router if the Edge Router already has an entry in his cache for registration of a given address in his white board or over the Backbone Link using Duplicate Address Detection mechanism designed to clear the mess if more than one router are keeping the same entry of a node in there white board. For this case, a new ND option is introduced in the NS/NA messages from routers to carry additional information to resolve the conflicts in all over domain range if any duplicate identity is present; the Owner Interface Identifier Option is used in NS/NA messages to carry the added information necessary for the resolution of conflicts: Transaction ID, Owner Interface Identifier, and Owner Nonce. In any case generally, the Edge Router of LoWPAN is in charge of the resolution which is the same Edge Router that handles all the registration processes of the LoWPAN nodes. A conflict only occurs when a Node already registered and router again receives registration request making it a duplicated address over the same network for that node and an IPv6 address that is already registered with a different OII at the same or another Edge Router. The address collision is only occurred while one node may be in sleeping node or normally moves from one LoWPAN to another, when it receives new LoWPAN it will try to get himself registered to that new edge router or may be contact the relaying router to get himself registered. At that very moment it will be checked which router has the registration entry of this node or its new node for this LoWPAN. Mobility of the nodes with in a same subnet or within a single domain of a LoWPAN router subnet is supported it has least effects on entries on white board, as the node is with on domain of a router no extra registration is necessary making no duplication of addresses in an Extended LoWPAN, a LoWPAN Node may move around from one Edge router to a new Edge Router visibly and at any time. The protocol for this mobility detection is designed to differentiate the mobility and clear out the registration states or any duplication among routers white board. The node registration triggered by an Edge Router that processes usually takes over an existing registration present among his domain or maintained by a defendant Edge Router this decision to transfer the registration from an Edge Router to another edge router is made by the Edge Router that is processing a Node Registration message depending on its states for that particular registration and ND exchanges over the Backbone Link if we talk about extend LoWPAN. If the node is already registered on a backbone link or to any other router with in a LoWPAN the chances of getting conflicts occurs when getting the registration of the same node start by, the resolution of such conflict is overcome by using classic Duplicate Address Detection mechanism; ità ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s quite simple who claim and have proof of the nodes ownership will succeed. Once a node registration message received to an edge router, the Edge Router checks for the existing registration for that IPv6 address in its LoWPAN whiteboard. If the entry does not exist then the Edge Router concerns the address over the Backbone Link using duplicate address detection mechanism. The edge router who is defending the address when gets the DAD message will reply back to this message with an acknowledgment and with owner identifier otherwise if the message is timed out then the edge router who advertised the DAD message will accept the registration of this node. It will create an entry on its white board and update the node with a positive confirmation message. If some router claims the ownership of the replies with his owner identifier and when the edge router get this message it will check the owner identifier interface in the message and matches it with the entries in his white board. If its present then the address is duplicate and already present on the network, taking this on account the request for registration is discarded and duplicate address detection is successful completed his task. If there are by any chance two routers claims to be the owner then checking the owner identifiers and matching them with the OII present in NA message will be checked and who has the Transaction ID will be claimed as owner and other request will be discarded. The router who a loss the registration has to keep the entry in his white board till the time period of this registration is expires.

Double Deceit - Original Writing :: Papers

Double Deceit - Original Writing I didn't know anything about him, until he stepped out of the car. He looked around, taking in his surroundings, and I realised he was an army man, like I used to be. He stepped towards me, and asked innocently, "Excuse me, but is this New London Road?" I looked carefully at him, quickly recalling the password "No sir, this is New York Avenue" He shook my hand quickly, and nodded to the car. No introductions were required. The less I knew about him the better - for both of us. I looked out of the windscreen the whole way. The streets of New Yorkwere scary, but right now, the inside of this car was a lot scarier. I was used to looking at people straight in the eye, I was an army person. Yet now, that was useless. This was a different mission. After a full half-hour of driving, the car suddenly stopped. The man kept looking at the staring wheel, and said "codename Steve". It was understood immediately, and I quickly replied "John". No other words were needed. He quickly blindfolded me, as I had done many prisoners in the war, and drove again. After an hour, my legs began to hurt. Being six-foot tall, it was difficult to sit in a car for this long. I also wanted to itch my hair badly. I knew that people like 'Steve' did not like the idea of me moving my hands around, but I felt as if a dark bug was crawling around my hair, clearly visible on my grey hair. We finally reached the destination. I was taken out of the car, and frisked before I entered. I knew I had entered the building when I felt a sudden rise in temperature. My blindfold was removed and I found myself in a room, completely plain. It was weird. I had always imagined that terrorists used dark rooms, with cracks everywhere. This room was different. There was one chair and one window. The window had

Condoleezza Rice Essay -- Politics Political

Condoleezza Rice   Ã‚  Ã‚  Ã‚  Ã‚  At this point in time the name and image of Condoleezza Rice is commonplace among the majority of informed Americans. As the first female to serve as the National Security Advisor to the President of the United States, Dr. Rice was propelled even further into the spotlight following the attacks on America on September 11th 2001. I too, like most Americans, saw a lot more of Condi, as she is known by her many friends and colleagues, after September 11. Clearly she was intelligent and always remained calm and poised in the face of adversity and standing before the cameras. I also noticed and appreciated her articulation and was even moved by what seemed like her stoic yet compassionate presentation. It was not until I read Dr. Rice’s biography, Condi, by Antonia Felix, however that she gained my utmost respect. By the 21st century a black successful black female is not as uncommon as it was fifty years ago. Black women had fought their way to the top in many arenas, including political such as the U.S. Senate. What is truly amazing about Condi’s story is speed and finesse with which she ascended to the top of everything she took on. An endearing friendship and mutual loyalty with both of the George Bushes surely did not hurt her. Condi’s  Ã‚  Ã‚  Ã‚  Ã‚   success was hardly limited to the world of politics. She approached music, fitness, academics, sports, religion, and family with the same decisiveness, consistency, and determination that she brought to the public sector. Condi is also no stranger to controversy. Now more than ever she faces a host of critics, especially regarding her supposed knowledge of possible terrorist threats before they came to pass on September 11. Her Republican politics made her less than popular among African Americans although she maintains a more liberal perspective on social issues and remains pro-choice. In spite of her ups and downs it is ultimately her unfaltering character to which sh e can attribute her success as well as her status as what many call the most powerful woman in politics.   Ã‚  Ã‚  Ã‚  Ã‚  The high academic pursuits of the Rice family did not exactly begin with Condoleezza and her generation. The foundation of this idea can be seen in chapter 2 of her autobiography in which the author begins the chronological record with a look at Julia Head Rice. Julia was born into slavery, albeit house slavery which was h... ...onsibilities were never ending and she approached them with the same grace and drive as she does everything in her life. Although the book end its documentation in 2002, shortly after 9/11, Condi’s duties have become no less urgent. Since that time she has had to defend her Administration against suggestions that the attacks could have been prevented and has done so quite well. The 2004 elections have just been completed and George W. Bush is returning to the White House for another term. Former Secretary of State Colin Powell has submitted his resignation and Condoleezza Rice has been nominated as a predictable replacement. If she survives the Senate approval hearings she will become the first black female and second female to fill the role. While I have full faith in her abilities I am concerned with the fact that without Powell in the National Security Council there will be no dissenting opinions. The proposed administration is politically homogenous. Surely Dr. Rice wo uld understand this concern as she herself is quoted in the opening lines of chapter 8 of her biography as saying â€Å"If you find yourself in the company of people who agree with you, you’re in the wrong company.†

Introduction This article discusses the comparison between archives and records system in South Africa and Botswana. In this study, they used the best approach to draw conclusions and make recommendations in both archives. They have been doing research on both the archive and collect data from the questionnaire. In the survey, found that achieve found in their country are not recognized and have a very weak system insufficient staff. Government does not care about these archives. They also, lack of funds and infrastructure not strong. Leaders there also overlooked in this matter. They just take this trivial. South Africa and Botswana have freedom in care of the problem. This task is only given to the subordinates to run. This study aims to suggest the best way to protect the archive. They are to reveal all the goodness in charge of the National archives. They also want to guide the two countries in maintaining and managing the archive with a more efficient way. They also want to share ways to evaluate existing records in the archives for future generations. Maybe the record will be useful for all future generations. This article is first issued to compare the situation of archives in south africa and bostwana. Authors of this article hope this article can help employees make the best archives in the evaluation record. Objectives The purpose of this article is published to study the performance of records management between the two nations of South Africa and Botswana. The main goal of this article is to review the archives they are upgraded or left alone so. Second, they want to discuss about the structural in building and their placement in the archive records. Third, a guide to the records to keep records in the archiv... ... both countries, namely South Africa and Botswana should be independent and reports directly to Parliament when there is a problem. This will bring greater recognition and support that they need to be more proactive in its role. In public opinion, the archives in South Africa should be moved to the prime minister's office because it has wide powers. Skilled workforce also plays a vital role in developing all the things in all the activities in the archives. To get skilled staff, both countries should provide adequate facilities to its employees rather they are interested in making the work. Furthermore, the government should retain skilled staff rather mandate in the archive does not fall to normal. Government should sacrifice a little reward for skilled staff. The government should also take archivist from outside to teach staffs were unclear on the archive system.

Lunar Phases Essay

Lunar phase (or Moon phase) refers to the appearance of the illuminated portion of the Moon as seen by an observer, usually on Earth. The lunar phases vary cyclically as the Moon orbits the Earth, according to the changing relative positions of the Earth, Moon, and Sun. One half of the lunar surface is always illuminated by the Sun (except during lunar eclipses), and is hence bright, but the portion of the illuminated hemisphere that is visible to an observer can vary from 100% (full moon) to 0% (new moon). The boundary between the illuminated and unilluminated hemispheres is called the terminator.The lunar effect is a theory which overlaps into sociology, psychology and physiology suggesting that there is correlation between specific stages of the Earth’s lunar cycle and deviant behavior in human beings. It is a pseudoscientific theory, however. The claims of a correlation of lunar phases to human behavior do not hold up under scientific scrutiny. Over the past 30 years, even more evidence has emerged to stress that this is pseudoscience. The theory is sometimes also referred to as the Transylvanian hypothesis or the Transylvanian effect in scholarly literature.The notion behind the lunar effect has fascinated many behavioralists and warranted many experiments and studies. Most experiments, however, have found no correlation between the variables and, thus, refuted the theory.There are some studies which have results the researchers claimed supported the theory. For example, a study concluded that schizophrenic patients show signs of deterioration, in terms of quality of life and mental well-being, during the time of a full moon. Some researchers have claimed that there were strong positive correlations between physiological changes such as induced seizures in epileptic and non-epileptic people and the full moon period in studies they conducted. One study concluded that a statistically significant correlations for gastrointest inal bleeding among males in particular during this time. However, most of these findings are based on small-scale research. On the other hand, the majority of scientific research seems to refute the theory of the lunar effect. Psychologist Ivan Kelly of the University of Saskatchewan (with James Rotton and Roger Culver) did a meta-analysis of thirty-seven studies that examined relationships between the moon’s four phases and human behavior. The meta-analysis revealed no correlation. They also checked twenty-three studies that had claimed to show correlation, and nearly half of these contained at least one statistical error. Kelly, Ronnie Martins, and Donald Saklofske evaluated twenty-one studies of births related to the phase of the moon and found no correlation. The scientific data â€Å"supports the view that there is no causal relationship between lunar phenomena and human behavior†. (Diefendorf 2007:113)A study of 4,190 suicides in Sacramento County over a 58-year period showed no correlation to the phase of the moon. A 1992 paper by Martens, Kelly, and Saklofske reviewed twenty studies examining correlations between Moon phase and suicides. Most of the twenty studies found no correlation and the ones that did report positive results were inconsistent with each other. Psychologist Arnold Lieber of the University of Miami reported a correlation of homicides in Dade County to moon phase, but later analysis of the data — including that by astronomer George Abell — did not support Lieber’s conclusions. Kelly, Rotton, and Culver point out that Lieber and Carolyn Sherin used inappropriate and misleading statistical procedures. When more appropriate tests were done, no correlation between homicides and the phase of the moon was found.Astronomer Daniel Caton analyzed 70,000,000 birth records from the National Center for Health Statistics, and no correlation between births and moon phase was found. Kelly, Rotton, and Culver report that Caton examined 45,000,000 births and found a weak peak around the third quarter phase of the Moon, while the full moon and new moon phases had an average or slightly below average birth rate.In 1959 Walter and Abraham Menaker reported that a study of over 510,000 births in New York City showed a 1 percent increase in births in the two weeks after full moon. In 1967 Walter Menaker studied another 500,000 births in New York City, and this time he found a 1 percent increase in births in the two-week period centered on the full moon. In 1973 M. Osley, D. Summerville, and L. B. Borst studied another 500,000 births in New York City, and they reported a 1 percent increase in births before the full moon. In 1957 Rippmann analyzed 9,551 births in Danville, PA and found no correlation between the birth rate and the phase of the moon.A fifteen month study in Jacksonville, Florida also revealed at least no lunar effect on crime and hospital room admittance. In particular:There was no increase in crime on full moons, according to a statistical analysis by the Jacksonville Police Department. Five of the fifteen full moons had a higher than average rate of crime while ten full moons had a lower than average rate. The higher-than-average days were during warmer months. Statistical analysis of visits to Shands Hospital emergency room showed no full moon effect. Emergency room admissions consistently have more to do with the day of the week.The word â€Å"menstruation† is etymologically related to â€Å"moon†. The terms â€Å"menstruation† and â€Å"menses† are derived from the Latin mensis (month), which in turn relates to the Greek mene (moon) and to the roots of the English words month and moon—reflecting the fact that the moon also takes close to 28 days to revolve around the Earth (actually 27.32 days). The synodical lunar month, the period between two new moons (or full moons), is 29.53 days long. Some authors believe women in traditional societies without nightlighting ovulated with the full moon and menstruated with the new moon. A few studies in both humans and animals have found that artificial light at night does influence the menstrual cycle in humans and the estrus cycle in mice (cycles are more regular in the absence of artificial light at night), though none have demonstrated the synchronization of women’s menstrual cycles with the lunar cycle. One author has suggested that sensitivity of women’s cycles to nightlighting is caused by nutritional deficiencies of certain vitamins and minerals. Other animals’ menstrual cycles may be greatly different from lunar cycles: while the average cycle length in orangutans is the same as in humans—28 days—the average for chimpanzees is 35 days. Some take this as evidence that the average length of humans’ cycle is most likely a coincidence.
