Battle of Okinawa in World War II

Battle of Okinawa in World War II The Battle of Okinawa was one of the largest and costliest military actions during World War II (1939–1945) and lasted between April 1 and June 22, 1945. Forces Commanders Allies Fleet Admiral Chester NimitzAdmiral Raymond SpruanceAdmiral Sir Bruce FraserLieutenant General Simon B. Buckner, Jr.Lieutenant General Roy GeigerGeneral Joseph Stilwell183,000 men Japanese General Mitsuru UshijimaLieutenant General Isamu ChoVice Admiral Minoru Ota100,000 men Background Having island-hopped across the Pacific, Allied forces sought to capture an island near Japan to serve as a base for air operations in support of the proposed invasion of the Japanese home islands. Assessing their options, the Allies decided to land on Okinawa in the Ryukyu Islands. Dubbed Operation Iceberg, planning began with Lieutenant General Simon B. Buckners 10th Army tasked with taking the island. The operation was scheduled to move forward following the conclusion of fighting on Iwo Jima which had been invaded in February 1945. To support the invasion at sea, Admiral Chester Nimitz assigned Admiral Raymond Spruances U.S. 5th Fleet (Map). This included the carriers Vice Admiral Marc A. Mitschers Fast Carrier Task Force (Task Force 58). Allied Forces For the coming campaign, Buckner possessed nearly 200,000 men. These were contained in Major General Roy Geigers III Amphibious Corps (1st and 6th Marine Divisions) and Major General John Hodges XXIV Corps (7th and 96th Infantry Divisions). In addition, Buckner controlled the 27th and 77th Infantry Divisions, as well as the 2nd Marine Division. Having effectively eliminated the bulk of the Japanese surface fleet at engagements such as the Battle of the Philippine Sea and the Battle of Leyte Gulf, Spruances 5th Fleet was largely unopposed at sea. As part of his command, he possessed Admiral Sir Bruce Frasers British Pacific Fleet (BPF/Task Force 57). Featuring armored flight decks, the BPFs carriers proved more resistant to damage from Japanese kamikazes and were tasked with providing cover for the invasion force as well as striking enemy airfields in the  Sakishima Islands. Japanese Forces The defense of Okinawa was initially entrusted to General Mitsuru Ushijimas 32nd Army which consisted of the 9th, 24th, and 62nd Divisions and the 44th Independent Mixed Brigade. In the weeks before the American invasion, the 9th Division was ordered to Formosa forcing Ushijima to alter his defensive plans. Numbering between 67,000 and 77,000 men, his command was further supported by Rear Admiral Minoru Otas 9,000 Imperial Japanese Navy troops at Oroku. To augment his forces further, Ushijima drafted nearly 40,000 civilians to serve as reserve militia and rear-echelon laborers. In planning his strategy, Ushijima intended to mount his primary defense in the southern part of the island and entrusted fighting at the northern end to Colonel Takehido Udo. Additionally, plans were made to employ large-scale kamikaze tactics against the Allied invasion fleet. Campaign at Sea The naval campaign against Okinawa began in late March 1945, as the carriers of the BPF began striking Japanese airfields in the Sakishima Islands. To the east of Okinawa, Mitschers carrier provided cover from kamikazes approaching from Kyushu. Japanese air attacks proved light the first several days of the campaign but increased on April 6 when a force of 400 aircraft attempted to attack the fleet. The high point of the naval campaign came on April 7 when the Japanese launched Operation Ten-Go. This saw them attempt to run the battleship Yamato through the Allied fleet with the goal of beaching it on Okinawa for use a shore battery. Intercepted by Allied aircraft, Yamato and its escorts were immediately attacked. Struck by multiple waves of torpedo bombers and dive bombers from Mitschers carriers, the battleship was sunk that afternoon. As the land battle progressed, Allied naval vessels remained in the area and were subjected to a relentless succession of kamikaze attacks. Flying around 1,900 kamikaze missions, the Japanese sunk 36 Allied ships, mostly amphibious vessels and destroyers. An additional 368 were damaged. As a result of these attacks, 4,907 sailors were killed and 4,874 were wounded. Due to the protracted and exhausting nature of the campaign, Nimitz took the drastic step of relieving his principal commanders at Okinawa to allow them to rest and recuperate. As result, Spruance was relieved by Admiral William Halsey in late May and Allied naval forces were re-designated the 3rd Fleet. Going Ashore Initial U.S. landings began on March 26 when elements of the 77th Infantry Division captured the Kerama Islands to the west of Okinawa. On March 31, Marines occupied Keise Shima. Only eight miles from Okinawa, the Marines quickly emplaced artillery on these islets to support future operations. The main assault moved forward against the Hagushi beaches on the west coast of Okinawa on April 1. This was supported by a feint against the Minatoga beaches on the southeast coast by the 2nd Marine Division. Coming ashore, Geiger and Hodges men quickly swept across the south-central part of the island capturing the Kadena and Yomitan airfields (Map). Having encountered light resistance, Buckner ordered the 6th Marine Division to begin clearing the northern part of the island. Proceeding up the Ishikawa Isthmus, they battled through rough terrain before encountering the main Japanese defenses on the Motobu Peninsula. Centered on the ridges of Yae-Take, the Japanese mounted a tenacious defense before being overcome on April 18. Two days earlier, the 77th Infantry Division landed on the island of Ie Shima offshore. In five days of fighting, they secured the island and its airfield. During this brief campaign, famed war correspondent Ernie Pyle was killed by Japanese machine gun fire. Grinding South Though fighting in the northern part of the island was concluded in fairly rapid fashion, the southern part proved a different story. Though he did not expect to defeat the Allies, Ushijima sought to make their victory as costly as possible. To this end, he had constructed elaborate systems of fortifications in the rugged terrain of southern Okinawa. Pushing south, Allied troops fought a bitter battle to capture Cactus Ridge on April 8, before moving against Kakazu Ridge. Forming part of Ushijimas Machinato Line, the ridge was a formidable obstacle and an initial American assault was repulsed (Map). Counterattacking, Ushijima sent his men forward on the nights of April 12 and 14, but was turned back both times. Reinforced by the 27th Infantry Division, Hodge launched a massive offensive on April 19 backed by the largest artillery bombardment (324 guns) employed during the island-hopping campaign. In five days of brutal fighting, U.S. troops forced the Japanese to abandon the Machinato Line and fall back to a new line in front of Shuri. As much of the fighting in the south had been conducted by Hodges men, Geigers divisions entered the fray in early May. On May 4, Ushijima again counterattacked, but heavy losses caused him to halt his efforts the next day. Achieving Victory Making skillful use of caves, fortifications, and the terrain, the Japanese clung to the Shuri Line limiting Allied gains and inflicting high losses. Much of the fighting centered on heights known as Sugar Loaf and Conical Hill. In heavy fighting between May 11 and 21, the 96th Infantry Division succeeded in taking the latter and flanking the Japanese position. Taking Shuri, Buckner pursued the retreating Japanese but was hampered by heavy monsoon rains. Assuming a new position on the Kiyan Peninsula, Ushijima prepared to make his last stand. While troops eliminated the IJN forces at Oroku, Buckner pushed south against the new Japanese lines. By June 14, his men had begun to breach Ushijimas final line along the Yaeju Dake Escarpment. Compressing the enemy into three pockets, Buckner sought to eliminate enemy resistance. On June 18, he was killed by enemy artillery while at the front. Command on the island passed to Geiger who became the only Marine to oversee large formations of the U.S. Army during the conflict. Five days later, he turned command over to General Joseph Stilwell.   A veteran of the fighting in China, Stilwell saw the campaign through until its finish. On June 21, the island was declared secure, though fighting lasted another week as the last Japanese forces were mopped up. Defeated, Ushijima committed hara-kiri on June 22. Aftermath One of the longest and costliest battles of the Pacific Theater, Okinawa saw American forces sustain 49,151 casualties (12,520 killed), while the Japanese incurred 117,472 (110,071 killed). In addition, 142,058 civilians became casualties. Though effectively reduced to a wasteland, Okinawa quickly became a key military asset for the Allies as it provided a key fleet anchorage and troop staging areas. In addition, it gave the Allies airfields that were only 350 miles from Japan.

What Are the Advantages Or Disadvantages of Being Born First free essay sample

The first-born is an only child until the second child comes along -transforming them from being the centre of attention, to then sharing the care of parents. Parents will also expect them to be responsible and set an example. The change from being the focus of a family may be quite a shock and so shape the first-borns subsequent outlook on life. Therefore first-borns may try to get back their parents attention and approval, by achieving success and recognition in their careers. It has been noted that first-borns are significantly more often found as world political leaders than any other birth order position. Being the youngest in the family can sometimes be a stifling and frustrating experience, especially if theyre looking to be taken seriously and treated like an adult. The last-born is more likely than the other birth order positions to take up dangerous sports. This may be a sign of the last-borns rebellious streak a result of being fed up with always being bossed about by everyone in the family. We will write a custom essay sample on What Are the Advantages Or Disadvantages of Being Born First? or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Middle children, however, have different issues. Middle c syndrome can mean fee sandwiched between two other more important people – an older sibling who gets all the rights and is treated like an adult and a younger sibling who gets all the privileges and is treated like a spoilt children. Middle-borns have to learn to on with older and younger children and this may contribute to them becoming good negotiators – of all the birth order positions they most skilful at dealing with authority figures and those holding inferior positions. What about only children they are more likely to show interest in academic pursuits rather than physical or outdoor activities. Only children will tend to get more time and attention from their parents than children with /siblings, this will often make them feel special but the downside is that they may suffer occasional pangs^ jealousy and loneliness when friends discuss their brothers and sisters and family life. I think to be a only child is not rather good, because these people are always selfish persons. 3. Mobile madness, do you think mobile phones are generally a good or a bad thing? How important do you think mobile phones are for young people in your country? How do you think mobile phones will change over the next 5 years? Mobile madness is an illness of our century, I think. In my opinion mobile phones as a mean of connection is a very good thing. But this medal has another side†¦ Many children feel themselves really isolated from their friends without mobile phone. They constantly connecting and chatting with each other by internet on the phone with help of such programs as ICQ. In our country mobile phone occupy the important place at the lives of modern people, and at the life of modern children too. Many sociologists say that if this trend continues two things are likely to happen. One is mobile phone addiction, where a person is incapable of forming and maintaining relationships without the help of mobiles. The second: Genuine conversation will be driven out by superficial communication, in which the act of contacting one another is all that matters, leading to a deterioration in the quality of relationships, indeed, the very fabric of society may be threatened. And of course mobile phones w ill change over the next five years, I can suppose that it will be something unusual, and may be something that absolutely won’t be look like our modern mobile phones.

Biology Yeast Experiment Essay Example

Biology Yeast Experiment Essay Example Biology Yeast Experiment Essay Biology Yeast Experiment Essay Design Experiment to investigate the effect of the concentration of Sodium Hydrogen Carbonate on the rate of photosynthesis using Cobomba plant. Aim: The aim of the experiment is to investigate the effect of the concentration of Sodium Hydrogen Carbonate (NaHC03) on the rate of photosynthesis using a Cobomba plant. Hypothesis: As the concentration of NaHC03 increases the rate of photosynthesis of the Cobomba plant should increase, as there is a greater presence of a carbon dioxide, obtained from the carbonate, which is a key reactant in photosynthesis. However it is also expected that the rate of photosynthesis should plateau with reater amounts of NaHC03, because the Cobomba plant will not be able to use all the extra, available C02 as its enzymes physically do not have the ability to do so. Background Information: When dissolved in water, NaHC03 produces carbon dioxide gas: . As can be seen in the equation for photosynthesis, carbon dioxide is a reactant in photosynthesis: 6 C02 + 12 H20 + photons -+ C6H1206 + 6 02 + 6 H20. The presence of NaHC03 means that C02 is more readily available in larger quantities, to speed up the process of respiration. However if a large amount of C02 is present in the water the Cobomba plant will not be able to use it all, as the nzymes cannot function quick enough. Other limiting factors may also cause the rate to slow, such as light intensity. As can be seen in the equation for photosynthesis, 02 is a product of photosynthesis and thus the rate of photosynthesis can be calculated by the amount of 02 released when photosynthesis occurs. Variables: Independent Dependent Controlled How to measure/control Amount of NaHC03 added to water Using the same weighing scale and weighing boat each time to measure the amount of NaHC03. Also using fresh tap water each time, so that the concentration of NaHC03 would be exact Amount of oxygen released Measured using the water bath and 100cm3 measuring cylinder Temperature of water Stayed in the same room, and used a heat barrier to prevent any heat from the lamp from affecting the rate of photosynthesis. Light intensity Used a lamp, kept in the same position each time to keep the light intensity equal for each repeat. pH of water Used tap water each time, and used fresh tap water for every measurement to ensure no NaHC03 was left in the water. Apparatus Application/Justification 1 x 500cm3 beaker To contain water to allow the NaHC03 to dissolve in 1 x glass funnel To put Cobomba plant under so that oxygen released goes into the easuring cylinder 1 x 10cm3 measuring cylinder To collect oxygen that is released Cobomba plant The plant which will respire and provide the results 5gof NaHC03 It will dissolve in water to release C02 which will affect the rate of respiration 100cm3 measuring cylinder To act as a heat shield from the light Lamp To ensure that the Cobomba plant has a constant light source to enable photosynthesis. Weighing scale and boat To measure the amount of NaHC03 Glass stirring rod To stir the NaHC03 when it is put in water to evenly distribute the concentration Stopwatch To ensure that time lengths are accurate for each time the xperiment is carried out Scissors To cut the Cobomba stem Ruler To measure length of Cobomba plant Method: 1. Measure a length of IOcm of Cobomba plant using the ruler 2. Fill the 500cm3 beaker, up to 500cm3, with tap water and place the Cobomba in the water underneath the glass funnel 3. Place the 10cm3 measuring cylinder upside down on top of the funnel, and ensure that it fills up with water 4. Set up a heat barrier using the 100cm3 measuring cylinder and fill it with water. Place it in between a lamp and the 500cm3 beaker 5. Switch on the lamp and start the timer 6. Once four minutes has passed stop the timer, and note down what the volume of 02 is in the measuring cylinder 7. Start the timer again, and after six minutes stop it. Note down the volume of 02 in the measuring cylinder 8. From this it can be deduced how much 02 has been collected 9. Repeat steps 1-4, but next measure 0. g of NaHC03 using the weighing boat and the weighing scales 10. Add the NaHC03 to the beaker and stir it with the glass rod 11. Start the timer and stop it after four minutes to allow the Cobomba to adjust to the water with added NaHC03, and make sure to note down the volume of 02 after four minutes 12. Then start the timer again for a further so minutes. When this time is up write dow n the volume, and from that it can be deduced how much 02 has been released 13. Repeat steps 10-12, making sure to replace the water in the beaker each time with new water, but adding another 0. gof NaHC03 each time 14. Repeat steps 1-13 a minimum of four more times to allow an average to be obtained Risk Assessment: Risk Precaution Being burnt by the lamp Take care and move slowly Swallowing a large quantity of NaHC03 or getting it in your eyes Do not put NaHC03 near to face 02 Amount of NaHC03 (g) +1- 0. 001 g Volume of 02 collected (cm3) +1- 0. 1 cm3 2 3 4 5 Average (2 s. f) Standard Deviation (2 s. f) 0 0. 2 0. 1 0. 2 0. 1 0. 2 0. 16 0. 05 0. 5 1. 0 1. 5 2. 0 2. 5 0. 2 0. 3 0. 4 0. 6 0. 7 0. 1 0. 8 0. 28 0. 44 0. 72 0. 06 0. 07 0. 05 0. 4 Graph to show the amount of 02 released with different amounts of NaHC03 from photosynthesis attached Discussion: The results show a positive correlation that evidences that as the amount of NaHC03 increases, so does the volume of 02 collected. This shows that NaHC03 speeds up the rate of photosynthesis, as all each amount time the experiment was done the time limits were kept the same but with more NaHC03 the olume of 02 increased. Therefore this partly proves the hypothesis, because it is shown that the addition of more C02, provided by the NaHC03, increases the rate of photosynthesis. However the rate of photosynthesis did not begin to plateau, as the hypothesis had stated. This may have been because there was not a great enough range of measurements of NaHC03 used to allow this pattern to be shown. Evaluation: The time restraints were quite limiting, and had there been more time a greater amount of repeats could have been done which would have allowed a more accurate average to be calculated. A systematic human error was not being able to add the NaHC03 to the water at the same time as starting the stop clock, which means there may have been a difference of a few seconds between each time the experiment was done. The act of measuring was not as precise as it could have been, and to resolve this equipment with a greater degree of accuracy could have been used. Another error was the decision to use small amounts of NaHC03. The consequence of this was that the digits of the results obtained were very small. Not only did this make them hard to measure, but also it meant that there was not a hugely significant ifference with the amounts of NaHC03 added to the water. Furthermore the ratio of for a comparatively large volume of water. Therefore a greater amount of NaHC03 should be used if this experiment were to be repeated again. Another human error was the repeated use of the same Cobomba plant. This may have affected the results, because the plant will have been respiring for a long time and also may still have remains of NaHC03 on it that would not make the next measurement of NaHC03 precise. To solve this the same mass of Cobomba plant, but from a different stem, could have been used each time. However this also poses problems as different stems may respire at different rates in the first place. If time had allowed then the time that the plant was given to respire could have been extended. This would have given a greater volume of 02, and the results may be clearer. An increased range of NaHC03 masses could be used, and this would hopefully show the results as expected in the hypothesis. The light intensity in the room may have changed during the time the experiment was done in, as it was turning into evening, and this may have had an affect on the results. To improve this, the experiment ould have been carried out in a dark room, but with several lamps shining on the beaker with heat barriers in front of them. This would have allowed the light intensity to remain constant. Conclusion: To conclude, it can be seen from the results obtained in the experiment that the rate of photosynthesis of the Cobomba plant increases with an increased amount of NaHC03 in its surrounding water. Therefore this suggests that C02 has an affect on photosynthesis, and that with greater amounts of it available there is a greater rate of photosynthesis.

C. A. Tripps Book Asserts Abraham Lincoln was Gay

C. A. Tripp's Book Asserts Abraham Lincoln was Gay Was Abraham Lincoln gay?  In his  book The Intimate World of Abraham Lincoln, historian C.A. Tripps  makes the case that Abraham Lincoln  was indeed gay and had several homosexual relationships throughout his life. However, the controversy surrounding the book overshadowed an important fact that Tripp revealed a fact even his harshest critics accept as true Ann Rutledge was not the love of Lincolns life. Tripps extensive new research proves it simply could not have been the case. And many experts, including Pulitzer Prize-winning Lincoln historian David Herbert Donald now concede it is so. A Firestorm of Debate As you might expect, Tripps book created a firestorm of debate most of it predictable along political lines. The left proclaimed a curious victory saying incorrectly that the book shows beyond all doubt that Lincoln was gay. The right responded angrily that Lincoln could not have been gay since he fathered four sons and they dismissed his so-called encounters as false and malicious. Tripp could not respond. He died two weeks after completing his book and one of the key elements of his work, proving that Lincoln and Rutledge were not star-crossed lovers, is in serious danger of being  ignored. Tripp told a friend shortly before he died that he knew the work would be controversial and that, while he believed he had made his case, he wanted each reader to draw his or her own conclusion. As the books editor, Lewis Gannett puts it: You get to a point where you just shake your head and say, How the hell did [Lincoln] do it? How did he save the union, survive the challenges of his troubled wife Mary, endure the deaths of two sons, preside over the bloodiest era of American history, all the while fending off widespread contempt, and in the end emerge a hero? A secretive, enigmatic, genius hero? With a manic and dirty sense of humor? Who had close and controversial relationships with other men his entire life? Lincoln is far from solved and probably never will be satisfactorily explained but Tripp has made the picture less murky. His accomplishment is stunning. Lincoln Loved Only One Woman And She Was Not Mary Todd For years, historians have assumed that Lincoln loved only one woman, Anne Rutledge and courted Mary Owens before marrying Mary Todd, whom he avoided whenever possible. Tripp, however asserts that Lincoln actually loved none of these women and has sex – though reluctantly only with his wife and mother of his children, Mary Todd. While it has never been proven, several historians contend that Mary Todd suffered from mental illness. â€Å"And it is true that Mary Lincolns actions, as reported by newspapers, often invited criticism from the public,† writes About 18th Century History Expert Robert McNamara. â€Å"She was known to spend money extravagantly, and she was often ridiculed for perceived haughtiness.† Intimate Relationships With Men Tripp contends his research into Lincoln’s private life suggests that his relationships with several men were more intimate  and possibly more sexual than those he had with any of the women he supposedly â€Å"loved.† For example, Tripp asserts that Lincoln shared a narrow  bed with Joshua Speed for at least four years  and that as president, he often shared the presidential bedroom with another man during the many times Mary Todd was â€Å"away.† Early Lincoln biographers, John G. Nicolay and John Hay, called Speed â€Å"The only as he was certainly the last intimate friend that Lincoln ever had.  In their analysis letters from Lincoln to Speed before and after Speed’s eventual marriage in 1842, Nicolay and Hay described Lincoln’s tone as â€Å"fretful,† like that of a military commander before a risky battle. Several of Lincoln’s letters were signed â€Å"Yours forever.†Ã‚   Through a plethora of letters and other personal data, Tripp’s book at least leaves the interpretation that Lincoln might have been gay. The Intimate World of Abraham Lincoln by C.A. Tripp was published by the Free Press, a division of Simon Schuster.

The Fight Against the Use of Animals for Laboratory Experiments Research Paper

The Fight Against the Use of Animals for Laboratory Experiments - Research Paper Example As of today, it is estimated that over 100 million animals are used every year worldwide for laboratory experiments. Several animal species are used such as mice, rats, guinea pigs, rabbits, fish, birds, dogs, and primates (Animal Aid Youth Group 1), where 75% of these animals accounts for rodents and cold-blooded animals. Animal protection societies have two different views and approaches to vivisection. One is the abolitionist view which believes that animal experiments are ethically wrong. They are the people concerned of the welfare who try to improve the conditions and treatments of animals used in experiments. The two views may be deemed as different but looking closely to the ideals and visions of both will show that they are closely aligned with each other. Both groups support the three R's approach - Replacement, Reduction, and Refinement. â€Å"Abolitionists would favor complete replacement, whereas welfarist would view reduction and refinement as steps along the way to co mplete replacement† (Yarri 194). ... This includes testing of animals on how memory works in the brain or on how to toxic substances affect the liver. Though some scientists believe that the fundamental research contributes indirectly to the advancement and development of active ingredients and therapies, anti-vivisectionist says that these finding are all overestimated (Animal Welfare Online). Next to fundamental research, the biomedical research accounts for the second largest area for animal research. The study specifically aims to study the prevention and treatment of diseases as well as the genetic and environmental factors related to disease and health. It is believed that human and veterinary medicine had relied on animal experimentation for its advancement at some degree. However, as the technology improved over the past decades an alternative in-vitro methods have been utilized such as using cell, tissues and organs culture have greatly reduced the need of biomedical research (ANZCCART Australia 11). Anti-vivis ectionists also believe that instead of focusing on the diagnosis and control of disease through biomedical research, scientists and researchers should focus more on preventative medicines and the promotion of healthier lifestyles – especially epidemiology, human clinical trials, and other alternatives (Animal Welfare Online). In addition, advancements in science had stimulated the increased growth in genetic engineering. This involves the modification of genes to produce transgenetic animals. The requirement for this research is highly extensive since one transgenetic individual would need around 150 to 200 animals of the same species in order to have a successful research. This method usually results to adverse effects in animals â€Å"such as development of

Scaling Study Essay Example | Topics and Well Written Essays - 1250 words

Scaling Study - Essay Example Likewise, personal space is apparent in a broad range of situations – even in crowded conditions where in the physical space is very limited. An example of such situation happens in trains which are always packed with passengers. In this case, people engage in certain behaviors in order to maintain their personal space given the lack of physical space. Moreover, though it is not a physical concept, it is possible to quantitatively measure personal space through the use of a dimensional scale. In an attempt to do so, a questionnaire, in the form of a verbal frequency scale, was developed that contain ten items, describing different spacing behaviors that people engage in. In order to be more specific, these behaviors were limited to those commonly exhibited in the train – being a common setting for personal space studies. For each item, five response options were provided which are coded from 1 to 5 – the highest score corresponding to â€Å"Always† and the lowest to â€Å"Never†. However, there are two different types of items made – negatively and positively stated statements, respectively – such that coding of responses was reversed for those items which are negatively stated. The total scores for all the items would be added and the average would be computed. Given this scoring, the variable, personal space, can be operationally defined as the degree to which individuals engage in different behaviors in order to prevent interpersonal relations. The assumption is that individuals who keep a large personal space are likely to engage to different spacing behaviors; hence, a high score in the test entails a large personal space. Validity Measures In order to guarantee that that the questionnaire would measure what it is supposed to measure, two types of validity were established prior to the administration of the questionnaires. First, the content validity of the questionnaire was established by creating items tha t were all based on observations made by previous researchers in their studies of personal spacing behaviors in the train. As such, previous observations found in published journals were translated into personal statements that constitute the items covered. Second, while it is not a good indication of usefulness, the face validity of the questionnaire was maintained in order to appear acceptable and relevant to the respondents. The questions were worded in a simple manner to facilitate better understanding. Also, the questionnaire was formatted to the convenience of the respondents such that they would only have to encircle their response for each item. After establishing content and face validities, the questionnaires were then administered to ten respondents who can easily be contacted by the researcher any time. In order to ensure that the respondents can relate to the questions covered, only regular train passengers were chosen to participate in the study. Consequently, the same questionnaires were again administered to the same respondents after a period of one week in order to confirm the stability of results. All responses were coded and inputted in statistical software for analysis. Based on the results, the respondents scored high in the variable that was measured. This means that people do engage in certain activities and behaviors that would protect their personal space. These findings confirm the established theories and expectations on the said topic. As such, it can be deduced that the question
