Inter-racial Face Recognition Research Paper Example | Topics and Well Written Essays - 1000 words

Inter-racial Face Recognition - Research Paper Example The participants were briefed at the beginning of the experiment, and were debriefed after the experiment. Bearing in mind that the issue of inter-racial identification could be sensitive (e.g. participants may feel uncomfortable if they fail to recognize some of the faces) the participants were told about the possibility for them to withdraw their data whenever they wish, and also that, if they wish, their results can be removed from the final outcome data of the experiment. Table 1 shows that the Caucasian race is slow in face recognition than the Black race. This means that the Caucasians have some difficulties in recognizing faces of every individual they met in their life. This also implies that the Caucasian have some problems in familiarization. Table 2 shows the Black Recognition time (second and counts) Black formally dressed (neutral faces) have computed F value of 206.640, and the white Recognition time (second and counts) Black formally dressed (neutral faces) have computed value of 52.414 and the tabular value of F statistics 247. This means that we accept Ho because the computed value of F statistics is less than its tabulated value. This also means that white individuals are more sensitive to Cross-racial impairment than Black individuals. This implies that white individuals may have visual problems connected to the cones of the eyes which are responsible for fine detail detection and color recognition.

Tides Essay Example | Topics and Well Written Essays - 750 words

Tides - Essay Example (Enchanted Learning, 2008). The ability to accurately predict tides has a variety of important implications, including coastal navigation. (Wikipedia, 2008). Because tides have such important implications, it is important and useful to examine the processes by which changing tides occur. There are two high tides and two low tides every day, with about "12 hours and 25 minutes between the two high tides." (Cooley, 2002). The exact time the high tide occurs depends on the relative location of the moon to earth. The distance between the earth and the moon is a crucial factor in determining tides and tidal range. Two words that are helpful to understand in examining the distance between the earth and moon are "perigee" and "apogee." When the moon is at perigee, or its closest to the earth, the tidal range is increased. When the moon is at apogee, or its farthest distance from the earth, this range is decreased. (Whipple, 2007 & Wikipedia, 2008). The reason that the distance of the earth from the moon has such a profound effect on tidal range is because of gravitational pull. Although the mass of the moon is much less than the mass of the earth, the moon still pulls the earth towards it by means of its gravity. This gravitational pull causes two bulges in the surface of the ocean on opposite sides of the earth, and the spinning of the earth on its axis creates tides as the bulges change location. (Frances, 2005). Because water is always in motion and isn't stuck to the earth, water on the earth is most affected by the moon's gravitational pull. On the side of the earth that is near the moon, water is pulled toward the moon, but on the other side of the earth, there is also a bulge of water. This is because the earth as a whole is being pulled toward the moon by the side that is close to the moon but the water on the other side of the earth is not. (Cooley, 2002). One type of tide is called a spring tide. A spring tide refers to the occurrence of the greatest range in a tide's low and high. In other words, during this tide there will be the greatest distance between how high the water gets and how low the water gets. This happens when there is a syzygy. A syzygy refers to the lining up of the sun, earth, and moon. (Wikipedia, 2008). The reason that the tidal range is greatest during a spring tide is because the gravitational pull of the sun and moon combine to produce the highest highs and lowest lows of the bulging water. (Cooley, 2002). It is also interesting to note that Spring tides occur around the time of new and full moons. (Wikipedia, 2008). When there is a new moon, the moon is in between the sun and the earth. When there is a full moon, the The Proxigean Spring Tide is an especially high tidal range that occurs once about every one and a half years. It happens when the moon is new and is at proxigee. Proxigee refers to when the moon is at its closest perigee to earth. (Cooley, 2002). The opposite of a spring tide is a neap tide. A neap tide refers to the occurrence of the smallest range in a tide's low and high. Neap tides occur when th

Representation of Urban Culture in the Literary Works of Anzia Essay

Representation of Urban Culture in the Literary Works of Anzia Yezierska and Carl Sandburg - Essay Example In her fifty-year writing career, the major theme of organizing throughout her mechanism is the cost of acculturation and incorporation among refugees. Her stories offer nearby into the meaning of emancipation for refugees' mainly Jewish immigrant women. Many of her works of narrative can be branded semi autobiographical. In her writing, she illustrates a lot on her personal life as a migrant in New York's Lower East Side. Her works, therefore, trait elements of realism with serious notice to aspect and skilful utilization of Yiddish-English dialect. At the same time, sentimentalism and extremely romanticized typescript have encouraged some detractors to label her works as romantic. In All I Could Never Be and Red Ribbon on a White Horse, Yezierska figured out their love as an ideal amalgamation of two cultures that verifies disillusioning. This story of the Gentile tutor and suitor happened to an example that persisted throughout her works, as Yezierska inspected the alteration of imaginative migration women from greenhorns to Americans. The achievements of Anzia Yezierska early short stories led to a succinct, but noteworthy, relationship between the novelist and Hollywood. Movie maker Samuel Goldwyn acquired the rights to Yezierska's collection Hungry Hearts. The film was shot on site at New York's Lower East Side. ... In 2006, an original attain was collected to escort the film. Yezierska 1923 novel, Salome of the Tenements" was too shaped as a still picture. Although Yezierska own semi-autobiographical occupation had donated to this rags-to-riches picture, she found herself scratchy with person touted as a case of the American Dream. Irritated by the triviality of Hollywood and by her possess estrangement from her extraction, Yezierska arrived to New York in the mid-1920s and sustained publishing novels and stories. Carl Sandburg He was an American poet, historian, and author. He was born in Galesburg his parents were Swedish. He lived in the Midwest, primarily Chicago, in Flat Rock, North Carolina. He lived there with his wife and children's until his death that was in 1967. To a great extent of Sandburg's poetry fixed on Chicago, and he was a foremost figure in the group of writers belonging to this city who shaped the fictional association called the Chicago Renaissance. His well-known portrayal of the city is as Hog Butcher intended for the World/Tool Maker, Stacker of Wheat/Player among Railroads and the Nation's Freight Handler, /Stormy, Husky, Brawling, and City of the Big Shoulders. In 1916 Sandburg had his first real experience of sensation as a poet with the publication of his first openly applauded volume, Chicago Poems, of which the title poem, "Chicago," fascinated popular attention In the poem, he portray the city as "stormy, husky, brawling a curved brutal place. He portrayed the people of the city with a cruel realism: prostitutes, gangsters, browbeaten factory labours and their families ravenous on low wages. Sandburg's Chicago, though, for all its unevenness and brutality was alive brawny cunning.

Journal Review Essay Example for Free

Journal Review Essay The article authored by Lloyd and Craig (2007) describes important factors to consider when collecting a patient’s history.   The rationale behind the procedure is based on the increase in the responsibilities of nurses, which now includes taking the histories of patients.   The assessment of every patient is based on several components, of which medical history plays an essential part.   In addition to a patient’s history importance, the collection of this information by a nurse allows the establishment of a relationship between the patient and the healthcare professional. The article discussed in fine detail the critical stages of patient history taking.   In order to prepare for the collection of information, a nurse should be aware that a patient could come from various environments and show different medical conditions and thus respect plays a critical role the assessment of the patient condition.   The cultural and religious beliefs of every patient may be different and thus a nurse should be competent enough in recognizing such differences.   The importance of privacy and confidentiality is also important in this procedure. Communication skills are also important when taking the history of a patient.   The nurse should also be capable of listening to the answers of the patient.   It is also important to get the consent of the patient to disclose any information pertinent to the assessment of his medical condition.    History-taking also involves an appropriate order of questioning the patient and this generally starts with a question regarding the patient’s identity and then asking what his chief complaint is.   The precise details of the complaint will also influence the choices of diagnostic procedures that will be performed.   The article also enumerated the cardinal symptoms that are important to consider when taking a patient’s history. a.

Questions In paragraph formatanswer the following questions: 1. Consider the steps in the procedure used for the formation of zinc chloride.   Zinc was first reacted with hydrochloric acid, then zinc chloride was isolated using a steam bath and lastly it was weighed.   What errors could have occurred during the experiment that would cause your simplest formula to be incorrect?   Include at least 2 errors.   In your answer include how the error affected the simplest formula calculation. 2. Which error would cause the largest effect on your result? 3. How could the errors described in question 1 be reduced or eliminated? Answer- 1. During performing the experiments in laboratory, chances of error are probable to occur. Some errors can happen accidently, by human error by observing the due to environmental factors, instrumental disorders. The error that occurred during the lab experiment is that the compound could be over burned causing the compound to dissolve into the air. Weight of the compound should be taken right away otherwise it will be evaporated into the air and there will be change in mass or may be in the whole result of the experiment. Calculations may vary. 2. According to my perception, the error which would cause the maximum effect on the result is human error because if by mistake compound gets over burned or without concentrating during the experiment compound gets over heated it will evaporate in air and we will be left with less amount of compound. 3. We can reduce the error, if the weight of compound is done quickly after heating.   Evaporating dish should be immediately taken off from hot plate to reduce overheating of the compound or loss of compound by evaporation in air. Conclusion(s)- In conclusion the simplest formula is determined by performing this experiment. We get to know about the possible error that may occur while conducting the experiment.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   /3 Reference(s) 1.

Gender Differences in Multitasking: Texting During Lectures

Gender Differences in Multitasking: Texting During Lectures Today, the communication technology has been growing widely to the extent that we can communicate with each other anytime and anywhere. As long as there is Wi-Fi or network coverage, our smartphones, tablets or computers can be used as a communication tool or a gadgets for us to receive new information in the world. Consequently, this function is so easily accessed by all, we are able to receive text messages, phone calls, emails and social network notifications throughout the whole day. However, this can be either a blessing or a curse. As we are exposed to all these information and entertainments, these can be a distraction in our daily tasks. To be specific, students in college are able to access to all these functions most of the time, it has pushed students to multitask more often in their daily lives. These might interfere with their studies as multitasking involves in switching tasks from one and another as well as the attention (Judd, 2013). In a study done by Wilkes University, 95% of the students bring their phones to college every day and 91% of the students admitted to using their cellphones during lectures (Harris, 2013). This has shown that most students tend to multitask in class as they listen to the lecture and use their phone at the same time for either text messaging, social networking or any other purposes. However, research on multitasking have proven that the human has no ability to perform more than one overlapping task at the same time due to the interference occurs in human information processing system (Levy Paschler, 2001; Wood et al., 2012). In other words, students can hardly concentrate in class if they are using their phone at the same moment. This explanation is consistent to the findings of Bowman, Levine, Waite Gendron (2010) that students who instant message while reading take longer time to finish the task. For generations, the stereotype of women are better at multitasking is debated across the world. Although scientist in University of Pennsylvania has supported this statement by discovering females’ brains are connected from left to right, while men has more intense movement in certain part of the brain (Spencer, 2013), many research done on multitasking has rejected the idea. Buser and Peter (2011) reported that women suffer as much as men while multitasking and have no significant differences in productivity of tasks. Not only that, even Conner, Laws, O’Connor and Stoet (2013) found that women outperform men in multitasking, they pointed out that their results cannot be generalized as the empirical studies on gender differences in multitasking is insufficient. Theoretical Framework Living in this world where we are overwhelmed by all perceptual information, our human information processing system can detect, recognize and identify chunks of stimuli at the same time (Hedge, 2013). As so, in this context, attention has given the model a function to either enhance or inhibit information, in other words, our attention chooses which certain information for further processing or ignore (McClelland, 2007). However, when two information are presented and are asked to process at the same time, the ability to attend both fully will be impaired as there are insufficient capacities in the information processing system; this attempt of trying to focus on multiple stimuli at one time is also known as divided attention (McClelland, 2007). One of the example of divided attention is multitasking, which can be defined as performing more than one task simultaneously or switching from one task to another back and forth (APA, 2006). In the human mind, multitasking is managed by a process called executive control; and to decide which cognitive processes and when it is performed, the executive control system will go through two stages – the goal shifting (decision of what to do) and role activation (action of switching task) (Meyer, Evans Rubinstein, 2001). Hence, people tend to repeatedly switch between tasks to achieve two things at a time without constant awareness; although it might seems productive and efficient, it is explained that multitasking leads to more mistakes and more time consumed as there will be brief mental blocks during switching of tasks (Meyer, Evans Rubinstein, 2001). Past Research Many past research have shown that multitasking in class can lead to poor academic performance. Junco (2012) conducted a research examining the relationship between in-class multitasking and academic performance, by giving out survey forms to a large number of students (N = 1,839) measuring their technology usage in class and internet skill to be compared to their grade point average (GPA). He then reported that constant multitasking in class (which include surfing social networking website, chatting and text messaging) has a significant negative correlation with students’ over semester GPA (Junco, 2012). Additionally, Carrier, Cheevar, Lim and Rosen (2011) did an experimental study on the frequency of text messaging interruption during a lecture has found that students in High texting group (16 messages or more) scored significantly lower than the Moderate texting group (8 to 15 messages) and No or Low texting group (0 to 7 messages) in the quiz after a 30 minute videotaped l ecture. Through the cross-cultural analysis of surveys results on mobile phone etiquette and multitasking in class, it showed that Americans and Chinese students both believe using cellphone in class will not interfere their learning but Americans students find it more appropriate to text in class than the Chinese; additionally, no gender significant difference is found (Rosenfeld, 2014). Many other research have furthered this study by doing an experimental study on multitasking in class with the awareness of cellphone distraction. Even many students did not believe that using their smartphones in class is a distraction from their learning, the scores of the short quiz given after the same lecture between students who use cellphones in class and students who listen to lecture without cellphones have a significant difference where students who anticipate in communication technology have a lower score (Elder, 2013). This result is consistent to the findings of a mixed experimental study on th e relationship between self-regulation, attention and cognition learning ability in classroom learning, which reported that college students who constantly self-regulate tend to have a better cognition learning by sustaining their attention during lecture as they text less (Klausner, Wei Wang, 2012). Besides, during an accounting principle lecture in Columbus State University, the half of 62 students who are allowed to multitask in class in the form of communicating with each other through texting did worse in the exam than the other half of students who are not allowed to use their cellphones during lecture (Ellis, Daniels Jauregui, 2010). Although in this study they did a comparison between male and female, they found that gender has no significant impact on learning ability without taking account of whether they multitask or not (Ellis, Daniels Jauregui, 2010). This research is similar to a recent experimental study which both groups of psychology students, who are asked to text and to switch off their phones during a short 20-minute lecture, are then given a short quiz to test their learning ability; the researchers concluded that texting in class is a strong distraction during lecture like other past research, but no gender comparison is done (Dietz Henrich, 2014). Howeve r, in the research of gender difference on multitasking have shown that women suffer as much as men in divided attention while completing multiple task at the same time and choose to avoid multitasking upon free will (Buser Peter, 2011; Strayer, Ward Watson, 2013). Description of Study Although many research has done on student multitasking capabilities in class (Carrier, Cheever, Lim Rosen, 2011; Ellis, Daniels Jauregui, 2010; Gingerich Lineweaver, 2013) and gender differences in multitasking (Buser Peter, 2011; Conner, Laws, O’Connor Stoet, 2013), there are limited research that compared male and female students’ academic performance if they multitask in class. In this study, we will be examining the gender difference in multitasking during a lecture. The aim of this experimental study is to see whether male or female students can multitask better while learning. All participants recruited for the study will be separated to different groups based on gender and will undergo one experiment each, either texting during lecture or no texting during lecture. As all participants will have to attend a half an hour English Literature class, the no texting group will not be allowed to access to their cellphone. However, for the texting group, each participant will receive a text message every 5 minutes and is required to reply. At the end of the experiments, all four groups of participants will be given a quiz to test their understanding of the lecture. Based on Carpenter et al. (2012) and Ellis, Daniels and Jauregui (2010), we hypothesize that texting in class will lead to a poorer performance in the quiz. Then, based on Buser and Peter (2011) and Strayer, Ward and Watson (2013) on gender differences in multitasking, we hypothesize that there will be no differences in both gender on performance in quiz for texting during lecture. Method Design The independent variable of this study is gender differences in multitasking, with two levels, male and female; the dependent variable is quiz scores. This is a between subject design as the participants will be separated to different groups and only go through one experiment either texting during lecture or no texting during lecture. Participants Approximately 80 male participants and 80 female participants, from all races, will be recruited from different private colleges in Penang for the experiment. This is because all the past research used participants less than this amount. A total of 62 participants of both gender are tested on the study by Ellis, Daniels and Jauregui (2010); and a total of 67 participants are used in the study of Gingerich and Lineweaver (2013). The age of the participants will be 18 to 25 (M = 21.25), which most people in this age attend college. The participants are recruited through purposive sampling where they have to meet the 2 following criteria, enrolling in an undergraduate program and is able to understand English perfectly. The students will be participating the experiment voluntarily. Materials A half an hour lecture of English Literature Studies will be given to all participants. As the participants recruited are from variety of courses, this is to ensure that the students have not been to the lecture before and have no prior knowledge in it. At the end of the experiment, a 20 multiple choice question quiz based on the lecture will be given to the participants to answer. As for the treatment group, a total of 6 text messages will be send to the participants which consists of basic conversation questions, such as â€Å"What is your hobby?† Procedure This experimental study will be done in a big lecturer hall with a clear projector screen and perfect sound system. Before the experiment is conducted, all the participants will be asked to sign the inform consent form. After that, they will be divided into four groups, the male control group, the female control group, the male texting group and the female texting group. The students will be told whether or not they are receiving text messages. For all four groups of experiment (the female control group, the male control group, the female texting group and the male texting group), the lecturer and the English Literature lectures given will be same. However, on the treatment group for both genders, each participant will receive a text message every 5 minutes and they are required to reply the message before the next message comes. After the 30 minutes lecture is finished, all participants will be asked to take a short multiple choice questions quiz based on the class conducted. Once the students have finished the quiz, they are allowed to leave. Statistical Analysis As this experimental study only consist of one independent variable and one dependent variable, the data will be analyzed using SPSS with independent one-way ANOVA; and to see if there is significant differences between two means of independent groups. History: The Act Of God Defence History: The Act Of God Defence The Law of Tort is a developing and ever dynamic field and is a conception evolving through centuries. This field is used with principles under which tortuous liability can be demanded. Simultaneously, certain other principles are used, to oppose these claims for compensation. These counter claims, or defences are used to evict those innocent citizens from tortious liability who have been unfairly implicated with claims imposed on them. These defences were framed from time to time to keep up with the very basis of imposition of tortious liability on an individual- i.e, creating a sense of deterrence while keeping up with the basic values of justice. One such defence which will be discussed elaborately with cases subsequently is ACT OF GOD. MEANING Act of God means an event which happens independently of human action such as death from natural causes (Actus dei nemini facit injuriam), storm, earthquake, tides, volcanic eruptions etc., which no human foresight or skill could reasonably be expected to anticipate. For example, damage from a tornado or a lightning strike would be considered an act of God. Damage would not be considered an act of God if it is caused by the property owner. Vis is a Latin word meaning any kind of force, violence or disturbance to person or property. Vis major is an act of God. The doctrine states that a person is absolved of liability if it was directly caused by vis major. LEGAL DEFINITION Act of God was first judicially defined in Tennet v. Earl of Glosgow Lord Westbury, was first recognised by Blackburn J. in Rylands v. Fletcher and was first applied in Nichols v. Marsland and many other cases. Blacks Law Dictionary defines an act of God as An act occasioned exclusively by violence of nature without the interference of any human agency. A natural necessity proceeding from physical causes alone without the intervention of man. It is an accident which could not have been occasioned by human agency but proceeded from physical causes alone. Vis major is similarly defined, as A greater or superior force; an irresistible force. A loss that results immediately from a natural cause without the intervention of man, and could not have been prevented by the exercise of prudence, diligence, and care. According to Salmond act of God includes those acts which a man cannot avoid even by taking reasonable care. Such accidents are are the result of natural forces and are incoherent with the agency of man. Thus it is an act which is due to natural causes directly and exclusively without human intervention, and that it could not have been prevented by any amount of foresight and pains and care reasonably to have been expected from him i.e. the defendant . Accor ding to Lord Mansfield, it is something in opposition to the act of man. Conclusion: It has been said that it would be probably never be capable of complete, exact unassailable definition. But it has also been said that this untheological expression is well understood by lawyers. It is such a direct, violent , sudden act of nature that no man could forsee and if he can, he cant prevent it. ELEMENTS NATURAL CAUSES An act of God is an uncommon, extraordinary and unforeseen manifestation of the forces of nature, or a misfortune or accident arising from inevitable necessity. An act of god cannot be prevented by reasonable human foresight and care. The effect of ordinary natural causes may be foreseen and avoided by the exercise of human care. For example, the fact that rain will leak through a defective roof is foreseeable. In case of foreseeable causes, failure to take the necessary precautions constitutes negligence, and the party injured in the accident may be entitled to damages. An act of God, however, is so extraordinary and devoid of human agency that reasonable care would not avoid the consequences. Therefore in such cases the injured party has no right to damages. Acts of god are generally attributable to forces of nature. They are generally in the nature of accidents caused by tornadoes, perils of the sea, extraordinary floods, and severe ice storms. Snowstorms of great violence have been held to be acts of God. Whether freezes are acts of God depend on the locality and season of the year in which they occur, i.e., their foreseeability is affected to a greater extent than other natural occurrences by these factors. Catastrophic earthquakes and volcanic eruptions should be defined as acts of God since they measure up to the accepted definitions of act of God in every respect. However, fires are generally not considered acts of god unless they are caused by lightning. Whether or not a particular natural event warrants such an adjective is a function of such things as the intensity of the event, characteristics of the area, and climatic history. UNUSUAL VIOLENCE- BOTH SUDDEN AND IRRESISTIBLE AN OCCURRENCE NOT REASONABLY FORSEEABLE The basic and prime element of an act of god is the happening of an unforeseeable event. For this, if the harm or loss was caused by a foreseeable accident that could have been prevented, the party who suffered the injury has the right to compensation. However, the damage caused by an unforeseen and uncontrollable natural event is not compensable as it could not have been prevented or avoided by foresight or prudence of man. Moreover, courts are of the opinion that the act of God defence exists only if the event is so exceptional and could not have been anticipated or expected by the long history of climate variations in the locality. It is constructed by only the memory of man i.e. recorded history. The courts may even demand expert testimonies to prove that an event was unforeseeable. IMPOSSIBLE TO PREVENT BY ANY REASONABLE PRECAUTIONS AND ABSENCE OF HUMAN AGENCY CAUSING THE ALLEGED DAMAGE It means practically impossible to resist. Negligence constitutes failure to take the necessary precautions. In an incident where a human factor was present, even though the harm could not be prevented, the fact that the human factor exercised reasonable care and precautions to prevent the harm has to be proved if the defence of act of God has to prevail. If negligence is alleged and proved, the defence of act of God will fail. If a home owner was negligent in properly maintaining a tree that fell on a passerby, he cannot be exempted from liability by act of God principle. In Clark v. Multnomah, the Court made a decision that the flooding of a house was not an act of God where it was caused by the breakage of a pipe fitting in the house. The cause of harm was evidenced by the fact that a repairman had worked with the part that broke just hours earlier. ESSENTIALS There must be operation of natural forces like exceptional rainfall, storms, tempests etc. without any human intervention. The incident must be extraordinary and not which could be anticipated and reasonably be guarded. ORIGIN HISTORICAL EVOLUTION The term act of God occurs and is described in holy texts dating back to the 13th century, specifically referring to acts that God has undertaken. The act of God referred is that which is used in legal and insurance circles when discussing any act which is outside human control and governance and therefore not the responsibility of any individual or corporation. The term was first used in this way in the mid-19th century. Peter Simmonds Dictionary of Trade Products, 1858, uses the term: Force-majeure, a French commercial term for unavoidable accidents in the transport of goods, from superior force, the act of God, etc. In July 1803, The Times included this legal ruling given in a court case by Lord Ellenborough, which is in terms that we are now familiar with from our own household insurance policies: By Common Law, Carriers are insurers against every loss of property entrusted to their care, except losses arising from the Act of God, or the Kings enemies. Earthquakes, floods, hurricanes, tornadoes, wildfires, drought and a deadly tsunami are a long series of natural calamities of seemingly large proportions have been witnessed by us . Lives are lost, properties destroyed , and emotions shattered when these forces of nature tragically strike. The natures blow may be so intense that it may come as a total shock and baffle both to the direct victims of the disaster and, subsequently, to the accused tortfeasors Defendants are quick to claim act of God as a defence to these lawsuits. For three centuries, the act of God defence has been accepted in negligence and strict liability cases. Act of God, as a legal concept shows up not only as a defence, but also in discussions of duty and causation. At first glance, the act of God defence seems a simple, direct concept with few gradations or intricacies. Consequently, all too often, many lawyers have misused the phrase act of God to mean any unfortunate act of nature. In a sixteenth century opin ion, in the Shellys Case best known for the famous property law doctrine, the court wrote in terms of performance becoming impossible by an act of God, which was the death of one of the parties. In an attempt to give life to this notion of fairness, the courts in Shelleys Case and other early decisions drew lines between those acts which were natural and those which were caused by man, so as to forgive man for those acts that were beyond his anticipation or control. The court stated: It would be unreasonable that those things which are inevitable by the Act of God, which no industry can avoid, nor policy prevent should be construed to the prejudice of any person in whom there was no laches. No further explanation of the phrase, Act of God, was provided by the court. The phrase again appeared in the 1702 case of Coggs v. Bernard, which invoked liability for a bailment by a common carrier. Justice Powell opined that a bailee shall answer accidents, as if the goods were stolen; but not such accidents and casualties as happen by the act of God, as fire, tempest for the bailee is not bound, upon any undertaking against the act of God. The act of God defence expanded from common carriers into other areas of strict liability. The Courts then extended the act of God defence to cases of negligence. The act of God defence received prominence in decisions construing the common-law liability of common carriers who were treated as insurers of the goods they carried. In 1785, Lord Mansfield delivered a unanimous opinion in Forwardv. Pittard which involved an accidental fire for which the carrier was in no way at fault. The court clearly established a rule of strict liability for common carriers: It appears from all the cases for 100 years back, that there are events for which the carrier is liable independent of his contract. Again, in Forward, the English courts limited the act of God defence by excluding acts of man. In addition, the burden of proof was shifted from the plaintiff to the defendant to establish the existence of the act of God defence. Although the courts subsequently split on the liability issue for common carriers whose delay subjected its freight to damage from an act of God, there was a consensus that liability would result if the common carriers knew that the force of nature was coming. CASE LAW: In Nichols v. Marsland(1875)( Discussed in judicial cases section) APPLICATION Act of God is often a difficult defence to establish. It requires both the exclusion of human agency and unforeseeability to establish an act of God. For an event to be a legal act of God, the natural event must have been the sole and immediate cause of the injury, with no co-operation of man, or any admixture of human means. Generally speaking, then, the vis major defence can apply to a case involving damage or harm by a natural force, but only in circumstances in which that force is strong enough to overcome and nullify any potential contributory cause by a human agency. The issue is whether the magnitude of force is reasonably foreseeable such that a defendant should have taken precautions to avoid personal injury or property damage resulting from it. For example, a 55-mile-per-hour wind gust, though rare, is reasonably foreseeable in Wisconsin. However, a 200-mile-per-hour tornadic wind is probably not; the vis major defence would apply to personal injury or property damage caused by such a force, even if a human agency (for example, a product such as a window or door) was involved. With respect to rain: An hourly rainfall of three inches, while heavy, is not unforeseeable in Wisconsin; an eight-inch hourly rainfall probably is. A basement collapse would probably implicate the vis major defence in favour of a basement contractor in the latter circumstance but not in the former circumstance. When property damage or personal injury is caused in part by a natural force and in part by a human instrumentality, the plaintiff should argue that the natural force was foreseeable and should have been anticipated in a manner that would have avoided the damage. The defendant then has the burden to establish that the natural-force component of the cause was so huge and so monumental that it was not reasonably foreseeable. The point is that the occurrence of natural phenomenon need not be unique, nor need it be one that happens for the first time; it is enough that it is extraordinary or exceptional and so as it could not be reasonably anticipated and also it must be free from human conduct. The word vis major imports something abnormal and with reference to the context means that the property by the act of God has been rendered useless, for the time being i.e. it was rendered incapable of any enjoyment. Vis Major to afford a defence must be the immediate cause, the causa causans, and not merely a causa sine qua non of the damage complained of. The mere fact that vis major co-existed or followed on the negligence is no adequate defence. Before an act of God may be admitted as an excuse the defendant must himself have done all he is bound to do. The legal maxim Actus dei nemini facit injuriam means the Law holds no man responsible for the act of God. The important thing in regard to vis major is not the positive intervention of natural forces but a process of nature not due to the act of man and it is this negative side which deserves emphasis. It is thus a negation of liability. Complete exclusion of human cause is a difficult standard for a defendant to overcome, which likely explains why the defence is not commonly argued or upheld. As a result, modern courts sometimes characterize acts of God as unavoidable accidents because, although the terms often are synonymous, unavoidable accidents need not be free from human agency. ACT OF GOD AND INEVITABLE ACCIDENT DISTINGUISHED Every act of God is an inevitable accident but not vice versa. An Act of God is discrete and distinct from inevitable accident. In order that an accident may be an act of God it must have followed directly from natural causes without human intervention. In Nugent v. Smith, Cockburn, C.J. said All causes of inevitable accident, casus fortuitous meaning an uncontrollable accident, may be divided into two classes: Those which are occurred by elementary forces of nature not connected with the agency of man or other cause [Act of God] Those which arises either wholly or in part by agency of man. [Inevitable Accident] Example- 1. If a ship is pushed ashore by a violent storm, this is the Act of God; but if it is run ashore during a fog by mistake, however unavoidable on the part of captain, this is the act of man. If a building is set on fire by lightning, this is an act of God; but not so if it is done by human through falling of a lamp even though this was due to no negligence. INEVITABLE ACCIDENT ACT OF GOD Could not be prevented by the exercise of ordinary care, caution and skill A direct violent, sudden and irresistible act of nature as could not, by any amount of human care and skill have been resisted is Act of God. May be controlled by human beings 2. Not controlled by human beings. 3. Strict liability can be imposed on the tortious liability occurred due to inevitable accidents 3. Even strict liability can also not be Imposed in cases of torts arising out of acts of Gods 4. The courts have discretionary power in determining the defendants tortuous liability 4. No discretionary power Conclusion : The defence of inevitable accident is a more general defence and is distinct from the act of God in so far as it is dependent on human agency and not on natural forces and in the degree of unexpectability. ACT OF GOD NEGLIGENCE Negligence, in law, especially tort law, is the breach of an obligation (duty) to act with care, or the failure to act as a reasonable and prudent person would under similar circumstances. Both these defences (act of God Negligence) are based on reasonable foreseeability. In terms of foreseeability, the question is not whether a similar event has occurred before, but whether the risk that this particular mishap may occur is foreseeable. Thus, a flood, earthquake, hurricane, or other natural force need not have previously struck a particular location for negligence to exist. Liability may still exist if reasonable design, construction, operation, inspection, or maintenance. For a plaintiff to recover damages, this action or failure must be the proximate cause of an injury, and actual loss must occur. In cases of joint causation, where both human negligence and act of God have a role to play, the traditional sine qua non (but for), substantial factor, or legal causation tests apply. If the act of God is so overwhelming that its own force produces the injury independent of the defendants negligence, then the defendant will not be liable. If the damages suffered are incurred solely due to natural causes without any known fault, there is no liability because of the act of God. There are two ways of viewing this situation. The act of God either supersedes the defendants negligence, or the defendants negligent act is not a cause in fact of the injury. In either case, the defendants act did not cause the damage since the injury would have occurred anyway. The party injured in the accident may be entitled to damages. An act of God, however, is so extraordinary and devoid of human agency that reasonable care would not avoid the consequences; hence, the injured party has no right to damages. Accidents caused by tornadoes, perils of the sea, extraordinary floods, and severe ice storms are usually considered acts of God, but fires are not so considered unless they are caused by lightning. JUDICIAL CASES Nichols v. Marsland  [1]   In this case, The defendant had constructed certain artificial lakes on her land by damming up a natural stream at appoint higher up than the defendants land. An extraordinary rainfall, greater and more violent than any within the memory of witnesses, caused the stream and lakes to swell to such an extent that the artificial banks burst and the escaping water rushed on to the plaintiffs land and carried away four county bridges. Nichols, the plaintiff brought an action for damages on the plea that the defendant was liable under the rule in Rylands v. Fletcher  [2]  . HELD: The contention was rejected and the defendant was held not liable. The Court of Exchequer Chamber held that she ought not to be liable for an extraordinary act of nature which she could not reasonably foresee. It was said that one is only bound to provide against the ordinary operations of nature, but not against her miracles. Greenock Corpn. V. Caledonian Railway Co.  [3]   The facts were that the corporation in laying out a park constructed a pool for children in the bed of a stream and there altere its course and obstructed its natural flow. Owing to rainfall of extraordinary intensity, the stream overflowed at the pond and great volume of water poured down a streetand flooded down the property of a railway company. HELD: It was held that this was not damnum fatale and the Corp. was liable. Nichols case was distinguished on the ground that in that case it was the storing of water in a reservoir and not with interference with the course of natural stream and that anyone who does interfere with it must provide against even an extraordinary rainfall. State of Mysore v. Ramachandra  [4]   In this case, the State had constructed a reservoir for the supply of drinking water for the villagers of Nipani. But the construction was not completed and the over-flow channel linked with reservoir was partially constructed. Land and crops were damaged due to flow of water resulted from rain. The plaintiff filed the suit for damages. HELD: The State resisted the suit that it was the act of God. But, the court rejected the defence and observed Assuming an act of God such as flood wholly unprecedented, the damage in such a case results not from the act of man in that he failed to provide a channel sufficient to meet the contingency of the act of God. But for the act of man there would have been no damage from the act of God. T. Gajayalakshmi v. Secretary, PWD, Govt. of T.N.  [5]   The deceased, a cyclist, who was going on his way was electrocuted by the falling of an overhead electric wire. HELD: The court rejected the contention of Electricity board that it was an unexpected event due to rain and wind and that the snapping of the electric wire was an act of God. It also rejected the plea that the death took place due to the negligence of the deceased in his leaving the home that day in rain and wind. Mahindra Nath Mukherjee v. Mathuradas Chaturbhuj  [6]  . A cinema advertising board was placed on the roof of the defendant which fell down and injured the plaintiff. Plaintiff brought a suit against the defendant and contended that the board fell due to storm of unusual severity. But, it was observed that during the season of monsoon a storm of this magnitude is not uncommon. The defendant had not ensured or foresee that the fixing of banner on such a height is strong enough to face the pressure of storm during monsoon season. The Calcutta High Court held that such a storm cannot be said to be so unexpected that no human foresight could reasonably be expected to anticipate it and cannot be regarded as vis major or act of God. Hence, the suit was allowed and the defendant was found negligent. Before the act of God can be admitted the defendant could have taken reasonable care and done all that what he was bound to do. Kallulal v. Hemchand  [7]   The defendant constructed a building and it was collapsed and as a result of it, two sons of the plaintiff were dead. Before the day the building collapsed there was a heavy rain. The defendant pleaded the rain as an act of God HELD: The court observed that the Acts of God must be apparent on the face of the records. They must be known and affect largely to entire public. The defendant was held liable. The act of God or vis major can also be explained mathematically as follows: (i) Unprecedented + Unforeseen + Irresistible = Act of God (As it has been discussed in this Chapter in the cases Nichols v. Marsland; Mahindranath v. Mathura Dass) (ii) Unprecedented + Foreseen + Irresistible + Act of God (Nichols v. Marsland case) (iii) Precedented + Unforeseen + Irresistible = Act of God (Greenock Corporation case) (iv) Precedented + Foreseen + Irresistible = Act of God (Greenock Corporation and Mahindranath cases) EXAMINING ACT OF GOD PRESENT SITUATION Vis Major as a defence depends on two ; lack of predictability and lack of control. If either criteria is missing, the defence fails. Both were solidly based for centuries on the lack of scientific knowledge. Man not only lacked the ability to predict the forces of nature, but also the ability to guard against, control, or otherwise minimize their impacts. In the words of the ancient mime writer Publilius, it is vain to look for a defence against lightning. Today, foreseeability is based not only upon the past, but also upon that which modern technology and science allow us to project into the future. Science has advanced to the point where we can understand many forces of nature, such as precipitation and flooding. Historically, we know which areas have been subjected to specific forces of nature. Scientifically, we can predict the areas which may be subjected to such forces. At first glance, the act of God defence should continue to play a role in strict liability cases. Part of th e underlying purpose of the act of God doctrine was to ameliorate strict liability. In strict liability a number of exceptions have evolved. Whether a particular occurrence amounts to an Act of God is a question of fact, but the ambit of this defence is somewhat restricted. Increased knowledge seems to limit the unpredictable. Natural hazards are no longer a mystery to us. Hence, the applicability of the act of God defence has shrunk in inverse proportion to rapidly expanding concepts of foreseeability. Conversely, environmental changes at the global level have left some scope for Vis Major as a defence. Unforeseen disasters like the July 26, 2005 floods in Mumbai or the devastating Tsunami on 26 December 2004, which was the result of severe earthquake with its epicentre at Indonesia can still be attributed to acts of God. These disasters were completely unforeseen and any prior intimation about the same would not have helped bring the situation under control. Such natural catastrop he has left some scope for the use of Act of God as a defence. Flaws in The Common Laws Approach to The Act Of God Defence 1. The Problem of Increasing Event Foreseeability In terms of Event Foreseeability, there are two independent trends which suggest a strong possibility that climatic events which historically qualified as Acts of God may become increasingly foreseeable: improved meteorological techniques and the effects of climate change. It is undeniable that there is increased data available and increased forecasting powers inherent in the continuing development of meteorological science. This trend has two impacts on the foreseeability of such climatic events for purposes of the Act of God defence: (1) defendants can increasingly know that the hurricane or storm is coming with time to take some precautionary steps in response because they will be warned of it (so that it will be more difficult to say that the event was unexpected or unanticipated); and (2) climatic data of past storms will continue to accumulate (so as to support conclusions that the event is not unusual for the location at that time of year). In short, the climatic events which historically may have been considered Acts of God will be more foreseeable in the future and thus less likely to support the defence simply because we will know more and more about the weather. In short, as climatic change increases the frequency and intensity of hurricanes, heavy storms, and the flooding associated with such climatic events, it appears that it will be harder for defendants to claim that the events themselves or the consequences of those events were not foreseeable. Thus, the defence is likely to be diminished in its utility simply because it will be harder to satisfy the legal requirements relating to the Event Foreseeability necessary to invoke the defence 2. The Problem of Response Forseeability As the climatic events themselves become more foreseeable, Response Forseeability becomes more critical to the Act of God defence because the burden is on the defendant to show that it took reasonable precautions in light of the foreseeable risk. It is here that foreseeability in the context of the Act of God defence really breaks down because of the inability of the defendant to foresee what the adequate response is before the climatic event occurs. To illustrate the problem, consider a fact pattern taken from the Act of God case law: a warehouseman holding goods for a customer in a Gulf Coast state in which a hurricane could strike. Given that a significant climatic event (i.e. a hurricane in the Gulf) is foreseeable, the court will have to analyze whether the defendants actions were reasonable in light of the foreseeable risk. CONCLUSION Although the act of God defence that a defendant is insulated from liability for personal injury or property damages caused by a natural cause is rarely used, it may become more common and general in the future if predictions of disastrous weather events caused by global warming prove true. One prediction related to global warming is that catastrophic weather events such as hurricanes, tornados, and torrential rains will occur more often. All of these have the potential for causing extensive personal injury and property damage and consequently mental trauma. Therein lie the core for more frequent, common and general use of the vis major defence. Is it still viable? How might it apply as a defence to tort? The act of God defence is as common today as ever. Though, it is still not relied on very often, likely because of the difficulty of proving that human elements played no role in causing an injury. The potential application of vis major will expand if meteorological predictions concerning climate change through global warming come to accomplishment and realization. However, as these events become more common, the standard of what constitutes a reasonably foreseeable natural force will doubtless itself expand. This again would confine application of the vis major defence insofar as defendants become obligated to anticipate and account for effects of more extreme and dangerous natural phenomena, especially those associated with the weather. However, in the era of global climate change, courts can hardly pretend that causation can be determined to be natural or human. Storm patterns and frequencies are changing. Growing seasons are shifting. Glaciers are melting and seas rising. Global climate change will present courts with the kinds of difficult factual situations that make it impossible to pretend the old act of God divide should stand untouched. Even though a particular defendant in a given case may not have been demonstrably at fault, the act of God doctrine remains analytically flawed because it requires that nature be the sole cause of a phenomenon to the exclusion of all human action
