Stomata Lab Report Essay Example

Stomata Lab Report Paper During those high-carbon-dioxide times, lands with fewer stomata will have an advantage and will be common. On the other hand, when carbon dioxide levels are low, plants need many stomata in order to scrape together enough carbon dioxide to survive. During low-carbon- dioxide times, plants with more stomata will have an advantage and will be common. (Understanding Evolution) Therefore, the question to be tested will be if you count the number of stomata of the same species of leaf at different stages of life will the number of stomata be different? My hypothesis is if we count the number of leaf stomata at three different stages of life then the umber of stomata will be less as the leaf gets older because the leaf is dying. (Understanding Evolution) Procedure Approximately three leaves of the where gathered to use in this experiment. Each leaf was at a different stage of life: alive, dying, and dead. A thin cast of a tiny part of the surface of the underside of each leaf was created using NYC clear nail polish. The imprint of each leafs underside was viewed one at a time under a light microscope using the cast, which was carefully removed from each leaf with a piece of packing tape. The stomata were completely visible and were able o be counted under the lowest view setting of xx. The stomata of each leaf were observed and counted four times. When viewing the stomata in each leaf for detail, the setting of xx was used. This made the view of the stomata large enough to tell whether they were open or not. The number and description of the stomata of each leaf was recorded.

These averages were results f four different trials in which the stomata were counted and observed in the specified area of each plant, every trial having a new person count the stomata. The stomata of the dead leaf were closed; the stomata of the leaf that was alive were open. The stomata of the leaf that was dying varied. In some places, the stomata were opened, in others, they were closed. The stomata that were open were bunched in separate areas of the observed section of the leaf, as were the stomata that were closed. Neither of the different stomata were mixed between each other in the dying leaf. All three leaves stomata were scattered around n the observed area and did not have a noticeable pattern to their placing. Conclusion: The data gathered shows that there is, in fact, a difference in the number and the appearance of stomata in three different life stages of an American elm leaf. However, the differences in the number of stomata are slight, calculating to a difference of only 5. 25 stomata between the largest and smallest average. The leaf that was alive had the greatest number of stomata, followed by the dying leaf and then the dead one, which had the least number of stomata. The numbers of stomata seem to descend as the leaf dies. However, this difference s insignificant considering that the stomata that were counted were a part of a very tiny area of the leaf (smaller than a fraction of a centimeter). The difference of stomata in each leaf came out to only 5. 5, which isnt a large enough difference in the stomata of a small area of the leaf to be determined as significant. Further investigation would have to be performed in order to test this and get more accurate results. The difference that was significant was that of the appearance of the stomata. In the dead leaf, the stomata were closed; in the leaf that was alive, the stomata were open. The stomata o f the dying leaf however, aired. Parts of the section viewed under the microscope consisted of opened stomata, others consisted of closed stomata. This might be because the leaf wasnt completely dead, or parts of the leaf were still alive. When something is dying, the working parts of it do not stop functioning completely, they shut down at various times. This explains why some the stomata are open and some were closed. There was no significant difference in the number of stomata between the three leaves; however there was a dramatic difference in the appearance of the stomata in each leaf. If I were to re-do this lab in the future I would make ere to keep my fingers off of the viewing part of the tape. I think it may have altered our results in the end, like the number of stomata should have been without outliers. Another error that I have discovered was that we used different microscope power for the leaves. We should have used all the same power on each leaf for more accurate results to be sure we were viewing the same amount of area. The data also proves this because for the alive and the dying leaf we used the xx zoom, but we used xx zoom for the dead leaf. Id infer that we did this because the dead leafs stomata were closed which could have made them harder to see.

Anti-Terrorism as a Self-Fulfilling Prophecy Essay Example

Anti Anti-Terrorism as a Self-Fulfilling Prophecy Essay Anti-Terrorism as a Self-Fulfilling Prophecy Essay Anti Terrorism as a Self fulfilling Prophecy The issue of war against terrorism has been a dominant theme in our media today. Terrorists have been stereotyped as Middle Eastern, Muslim, cold blooded and hard headed suicide bombers who are out to destroy all that standing in the western world. The gargantuan international effort on the War on Terrorism has created a psychological construct where Islamic fundamentalism and the Middle Eastern race are now considered as potential terrorists. There have been numerous circumstances where Muslims and Arabic costume and color precipitated discrimination and hate campaigns. Movies and films of Rambo and Schwarzenegger portray terrorists as Islam fundamentalists triggering a host of discriminatory actions among the populace. Given the billions of dollars spent on the war against terrorism and the widespread and extensive media propaganda campaign, it should be logical to conclude that terrorism has been greatly diminished ten years after the September 11, 2001 tragedy. On the contrary, the War on Terrorism has become a self fulfilling prophecy where terrorist activity exponentially increased. To wit: The Rand Corporation for the National Memorial Institute for the Prevention of Terrorism (MIPT) reveals that there has been a 250 percent increase in terrorist activity from September 11, 2001 to September 2006 alone. If we divide post 9/11 into two phases until 2006, the first phase has 4772 fatalities from terrorist attacks and the second phase has 5177 fatalities (Conetta, 2006). Thus, all efforts to counter terrorism has only effected in their increase. The US war against Iraq, Iran, Afghanistan, Libya, North Korea and others in fact encourages ordinary citizens from these countries to launch attacks against the US comparable or even similar to terrorist’s acts. Instead of solving the roots of the problem such as creating an international atmosphere of peace and justice, anti terrorism campaigns have in fact sowed the seeds of war, injustice, and fan the fires of terrorism worldwide. Thus it has become a self fulfilling prophecy. The real proof that the anti terrorism campaign has become a self fulfilling prophecy is when we find ordinary citizens who are not in any way connected to terrorist groups performing terrorist acts. The recent bombing and massacre in an island in Norway killing 92 people did acts similar to the modus operandi of terrorists (bombing and shooting like in Mumbai) but acted alone. The Oklahoma bombing was done by a US soldier but imitated the acts of those who he fought during the Gulf War. The psychological construct created by suicide bombing and rampant shooting has in fact created an image where deluded and frustrated ordinary citizens can really act out their violent fantasies. There have been many cases in school campuses where some student would attack and massacre many students using bombs and high powered weapons. Terrorism according to Zulaika is now the dominant tropic space† in media, government, and all walks of life (Zulaika, 2009). This is further fueled by the imagination of nuclear war initiated by terrorists creating an apocalyptic nightmare that in turn fan the fires of Christian fundamentalists. Note that the â€Å"terrorist† who killed 92 people in Norway was a Christian fundamentalist. In fact the use of torture against suspected terrorists in Guantanamo bay was largely unprotected because of this powerful image against suspected terrorists. The problem with the Anti terrorism campaign is that it was blown too much in proportion so that the US who is supposed to be the champion of democracy and human rights is now seen as a torturer and a blanket bomber of civilians, an illegal eavesdropper of its own citizens, and an espouser of war. Indeed the War against Terrorism has not only been a self fulfilling prophecy but actually created the US as a number one terrorist as some critical groups contend. Bibliography Conetta, C.

Yonyous Business Operations in the Software Industry Case Study

Yonyous Business Operations in the Software Industry - Case Study Example The recession led all the software companies to change their business strategies. Likewise, Yonyou also developed its own strategies to sustain in the changing market environment. The investment in the R&D to promote product development eventually worked in company’s favor towards its expansion. Yonyou collaborated with companies like IBM and Atos to develop the cloud computing, which proved to be a step towards the future of IT. Yonyou Software Co. Ltd., headquartered in Beijing, China, is an accounting and ERP software company. It operates in mainland China, Japan, Hong Kong and Thailand. Founded in 1988, Yonyou has been ranked as no. 1 management software provider in China. The company excelled in Chinese markets as it could understand the Chinese management culture closely. In order to streamline its business, the company also outsourced its consulting and implementing services. The information technology industry went through several changes in last five years and all the companies had faced severe downturn or even ceased to exist. However, Yonyou has managed to adapt to the changing environment and sustained in the competitive industry. The growth of management software had slowed down after the great recession and economic crisis in 2008. The management software market in Asia had a much higher growth rate in 2011, although being a small portion of the global market. The manpower and materials cost had increased within the last decade in China, as a result, the companies were bound to adopt the management software system in order to avoid inefficient operations and management. Although, as compared to other developed countries, China still stands behind when it comes to investment in management software. China mentioned in the 18th national congress, that it will follow its own way to implementation of information technology on a national strategic level.

'Alternative dispute resolution is at the heart of today's civil Essay

'Alternative dispute resolution is at the heart of today's civil justice system, and any unjustified failure to give proper - Essay Example Early 1990s had been witnessing delays in the conduct of litigation in courts exacerbated due to complex procedures and interlocutory battles entailing heavy costs to the parties and the state exchequer as well. As stated by the English Centre for Effective Dispute Resolution (CEDR), British commerce can achieve cost savings of over ? 1 billion by avoiding time spent by the management, spoilt relationships, lost productivity and legal fees.1 Mediation method already has helped save about ? 6.3 billion since 1990.2 In a classical case decided in 2007 involving a claim of just ? 6,000, parties are reported to have spent nearly ? 100,000 as litigation costs. 3 Perceptions about mediation are still mixed as revealed by a survey of the Ministry of Justice in 2007. For 38 % of the respondents, mediation had resulted in cost savings and for 29 %, costs had increased. Those who had settled cases through mediation informed of cost savings except for 7 % of them for whom costs had increased. F or those whose cases could not be settled through mediation, 45 % of them stated cost increases, 19 % cost savings and 28 % did not see any difference in costs.4 Sequel to Lord Woolf’s report, the U.K. Government made it a condition as far as possible to provide for ADR in all government contractual disputes arising out of procurement contracts. 5 As a result, ADR was resorted to in 336 cases out of which 241 were settled with a resultant cost savings of ? 120.7 million. 6 in Royal Bank of Scotland v Secretary of State for Defence, the successful defendant was refused costs as it had not opted for ADR in line with the above said ADR pledge by the Government.7 An audit report of 2007 stated that non-availing of mediation in family disputes entailed additional cost of ? 74 million through legal aid i.e average legal cost for a non-mediated case amounted to ? 1,682 as against ? 752 for a mediated case. 8 Warren K. Wrinkler Chief Justice of Ontario notes with caution that mediati on if not successful ends up as an additional layer in litigation costs. 9 Time efficiency is another factor apart from cost factor. According to a report of the CEDR, in England 75 % of their cases were settled instantly (same day). 10 Mediated family disputes cases are settled faster at 110 days than non-mediated cases which take 435 days to settle. 11 Regardless of cost effectiveness and time efficiency, flexibility available in mediation towards mutually consensual resolution is absent in court led litigation. The English Alder Hey case that involved more than 1000 claims is a classic example of successful mediation that resulted in apology and erection of permanent memorial for the children whose organs had been withheld by the hospital. ADR provides for not only procedural flexibility but also of flexibility of outcome.12 Mediation offers larger number of remedies that include apology, explanation, enduring relationships, and undertaking by one party an obligation without any legal compulsion. 13 In order to have an effective mediation system, the 2008 EU Directive applicable for cross-border disputes states that member states should have legislation that ensures mediation that guarantees a predictable legal framework, provides for flexibility in procedures and ensures autonomy of parties. Besides, the mediation should be conducted in an effective, impartial and competent manner.14 The EU directive adds that it can be applied to internal mediation of the

Evidence - Essay Example in the calendar of the judiciary in the arrangement of the appointment of subject, in line with the proceedings concerning state party cases (Pontell & Stephen, 2010, p. 41). The California code of civil procedure states does not prevent an attorney to permit any kind of representative to stand before the courtroom and present the evidence and witnesses engaged in the proceedings. The mother is therefore entitled to a maximum period of twenty days to submit a respond to the jury of the state. An attached subpoena that the court issued at the beginning of the trial should be handed out as a means of showing proof of chamber sittings between the mother’s attorney and the jury. California’s Business and Professions Code, 349a puts the mother’s lawyer in a state where he or she has to hand out an advance note of the court case three months prior to the lawsuit commencement. As a result, the child and his attorney have ninety days to take action before the lawsuit begins and at this period, they have the ability to organize for the justification of the child. Nevertheless, it is of value noting the fact that there exists no specific type of note necessary, except where notification of the defendant of the legal basis of the claim and the type of loss sustained, including with the specificity the nature of the wounds endured. At this point, it is important to underline the fact that if the notice is served within 90 days of the expiration of the applicable statute of limitations, the time for the commencement of the action shall be extended 90 days from the service of the notice (Pontell & Stephen, 2010, p.

Difficulties Of Rene Descartes Cogito

Difficulties Of Rene Descartes Cogito The most important contribution of Renà © Descartes in the history of Philosophy is his cogito. In the same way, however, the cogito has also been the most critical problem of his philosophy. This essay will focus more on the difficulties of the cogito. But first, on the side of the cogito: one importance of the cogito is that it is the byproduct of the Method, which is another contribution of Descartes not only in modern philosophy, but also in the field of science. The origination of the cogito from the Methodic Doubt is quite anticipated: all prior knowledge and truths must be erased, unless they are indubitable. In other words, all knowledge and opinions are subjected to examination, whether they can survive the test of doubt. Descartes, having found the fact (or act) of his doubting indubitable, hence maintains the fact that his existence enables his doubting (or thinking) as a clear and distinct idea, and thus the conclusion: Cogito, ergo sum: I think, therefore I am. We understand therefore that the cogito is a product of deduction or inference. However, as I have said, the cogito is quite anticipated. This is because the rules of his Method lay down an algorithm that has a quite predictable result, as if laying down a theore tical step-by-step means to prove something that is already true. The cogito is also considered a product of intuition and not of deduction. However, as far as methods of analysis are concerned, Descartess Method and cogito are valid. Moreover, insofar as the solipsistic argument, the cogito is a rather fair argument. By this, I mean that the cogito is a solipsistic truth, or a belief in the self as only reality or basis of reality. When Descartes has proposed that all knowledge and opinions must be cleared off the mind (or must be brought into doubt), there is still in Descartes the belief that the only thing he can be sure of is that he exists. He cannot deny the fact that he exists, even if the very idea of his being is most accessible via experience (hence, this he must doubt also). Thus if Descartes denies his being in the first place, his cogito will never materialize as a basis for truth. But since Descartes adopts a solipsistic view, he is safe from committing contradiction. To put simply: insofar as the I is concerned (the I, which thinks and doubts), the I exists. Nevertheless, Descartes paradox, which is the cogito itself, is not an absolute oxymoron. By the cogito being a paradox, I mean the self-contradictory problem of the cogito; that is, the problem of which came first: the cogito or the sum. Using the Method of Doubt, the cogito seems to go before the sum, since it is the act of doubting/thinking that came before the conclusion for the act of existence. But in the context of Descartes, it is implied that thinking is actually in the context of being. Now the strength of the cogito argument is that it is a closed argument, relying only on the idea that existence constitutes thinking and thinking reflects existence. It is in these strengths of the cogito, however, that it is also problematic. First is on the solipsistic view. The very problem of the cogito here is the question of reality outside the I. Since Descartes uses himself and only himself in his basis for truth, anything outside himself can be doubtful or false, and thus cannot be a basis for truth. Only the thinking I, thus the human person, can prove and claim ones existence. Thus, the other for the thinking I is doubtful, insofar as the I is concerned. The problem is that Descartes is as if denying the existence of animals, plants and other things, since these things do not and cannot think. Moreover, after proving that he is a thinking thing, the next question that arises is: now how do we establish an edifice of knowledge? Descartes takes emphasis on putting a foundation for knowledge by first using the Method, but forgets how to formulate the next set of algorithm once the Method has been applied. The problem of the solipsistic ar gument of the cogito is that nothing more exists outside the selfs being a thinking thing. It only proves the existence of oneself insofar as the thinking I is concerned, and does not prove the idea and the existence of other things other than the self. Besides, other Is can think of me a mere fiction. In the problem of the solipsistic argument of the cogito, however, the idea of a Perfect Being other than the thinking self exists. Descartes said that since he is cogito (thinking/doubting thing), he is therefore an imperfect being. But since he is imperfect, he has an idea of a perfect thing, which can come only from a Perfect Being, which is God. Nevertheless, nothing more exists outside the thinking self aside from the self itself and God. Now the second weakness of the cogito is in its contradictory problem. Although the cogito (cogito-sum relationship) is a closed argument (like Spinozas freedom-necessity concept); one cannot ignore to question the validity of its argument. In this argument, whether the cogito conditions the sum or the sum conditions the cogito, the idea of existence is still in danger, because it is subject to doubt. The sum (I am) only works for the thinking I, but existence alone cannot prove thinking. Thus what seemed to be a safe closed argument is not free of loopholes at all, because existence in general is not enough to prove thought. Nevertheless, the cogito is concerned for the existence of ones being a res cogitans or thinking thing only. Moreover, that material objects exist because of God is another argument that branched out from the cogito. After concluding that the Supreme Being cannot deceive, Descartes proceeds to concluding that material objects thus also exist. However, this only results to another circular argument: cogito presupposes God, which tells the res cogitans that its ideas come from external objects; but then it is from these external objects that the cogito must doubt first before it realizes that it is a res cogitans, then assume the existence of a Perfect Being. Generally, we find Descartess Method of Doubt and cogito weak. The main premise that we cannot distinguish reality from dream is not even strong enough to be a basis for truth. Although Descartes skepticism is optimistic at finding a certain knowledge that we can know of, still it is rather destructive of the foundation of knowledge that is the objective of his skepticism in the first place. The problem is that Descartes proposes arguments for why everything can be subjected to doubt, such as the dream argument, the deceiving God argument, and the evil demon argument. It is difficult to follow Descartess advice because it is more difficult to prove a negation than proving otherwise (in the case of Descartes proving the negation of knowledge to prove the opposite), since if we convince ourselves with these arguments of Descartes, then we must act and think as if we are experiencing illusions and hallucinations all the time. This is of course difficult for us. In fact one example where we can prove Descartes could probably be right all along that an evil demon is deceiving us (e.g., dwhen something defies the laws of physics) is when we experience a Criss Angel trick. Perhaps we can say that the main problem of Descartess philosophy is both its extreme rationalist and non-rationalist approach. Descratess philosophy is rationalist because it proclaims reason as the only valid criterion for certain knowledge and thus truth. It is non-rationalist, however, in the sense that it somehow forgets other valid functions of the human mind or reason: that is reason as the faculty of mans sentient soul, can, aside from thinking and doubting, imagine, sense and feel.

Service Learning Essay -- Education Educating College University Essay

The Society for Experiential Education defines service learning as, â€Å"any carefully monitored service experience in which a student has intentional learning goals and reflects actively on what he or she is learning throughout the experience† (Staton 1). Service learning is a great opportunity to get extra learning experiences while also experiencing the community around the universities campus. â€Å"Service learning allows students to apply what they are learning from their instructors, peers, and readings to genuine tasks that occur outside the four walls of the classroom while simultaneously helping others† (Staton 1). Universities are using service learning to expand beyond the classroom and provide students with experiences that will benefit them in the future. Service learning provides students with some fundamental aspects of life that can simply not be taught in the classroom. Service learning is a very beneficial tool in expanding on class room topics in the real world. There are numerous reasons why universities should incorporate service learning into their curriculum. One way that service learning is so beneficial to college curriculums is that it will cheapen the price of credit hours. Many universities have made the service learning free credits, which will appeal to students when they are making the decision to attend school. And trust me, as a college student, the cheaper the credit hour the more appealing the school is. Another very beneficial aspect of service learning in curriculums is that it gives students a taste of the â€Å"real world†. â€Å"Service learning allows students to apply what they are learning to real-world problems, become more involved in the community surrounding the campus, and develop career g... ...nication† (Staton 3). The students in these classrooms really benefit from the extra communication skills that are taught by the college students. Service learning is a program that many universities around the country have turned to in order to improve their curriculum. It provides students with many excellent opportunities to go out in the community and get more then just a typical â€Å"college education.† The students who have been involved in service learning feel that they have become well-rounded human beings and have a taste of what it is like to function in the real world. Another great part of service learning is that not only the students benefit from it. The university, as well as the surrounding community are both rewarded by the program. Service learning is a great program that can be incorporated into any subject matter that a university offers.
