Johns Hopkins University admits 3,133 to the Class of 2021
Are you going to be a Johns Hopkins Blue Jay? Check your emails, because decisions are out! Johns Hopkins University has offered admissions to 2,542 students to the Class of 2021 this spring. JHU has consistently received large volumes of applications, but didnââ¬â¢t see explosive increase rates in applications like other universities this year. They received 24,644 applications just a little less than last yearââ¬â¢s number of applications, resulting in a 10.3% acceptance rate for their regular decision. They joined the enrolled 591 early decision students who are already members of the Class of 2021. Late last year, 1,934 student applied ED, marking a 30.5% acceptance rate. This makes the total admits 3,133 students and an overall acceptance rate of 11.8%. For the last 4 years, JHU have been increasing the proportion of women in every graduating class. This year follows the upward trend with 54% female in the Class of 2021. Jonhs Hopkins had an enrollment rate of 41% last year, so we should expect to see the same for the fall of 2017. JHU already have 23% committed from being accepted to the ED program, so weââ¬â¢ll see how many regular admitted applicants decide to enrol. Donââ¬â¢t let your application essays and materials go to waste. Turn your success into insights for future applicants bycreating a profile. Plus, you get to earn some extra money!

Lab Report on Ideal Gas Law Essay Example
Lab Report on Ideal Gas Law Essay Example Lab Report on Ideal Gas Law Paper Lab Report on Ideal Gas Law Paper We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards, turning the open end downwards after the tube was fully submerged beneath he surface. We then placed the canister directly below the opening of the test tube, and released the gas so that the bubbles rose into the test tube. Next, we used a cork whose head was larger than the opening of the test tube to block off the opening (without changing the pressure inside of the tube), so that we could transport the remaining water to a graduated cylinder. When doing this, it was very important that the water level inside of the tube was equal to that of the surrounding water in the bucket, because that ensured that since the eater pressure in the tube was the same as that of the surrounding water, the pressure of the gas would be the same as that of the surrounding air. Thus, we recorded the gas pressure to be the same as the pressure in the room, which was calculated to be 763. 0 meg. We poured the remaining water from the test tube into a graduated cylinder to calculate the difference between the original water volume and the volume remaining, because this difference was equal to the volume of the gas released. Next, we blow-dried and shook the canister to get rid the extra mass that would eave been added by any water that had clung onto it while it was in the bucket, and weighed the canister again. We subtracted this mass from the original mass of the canister to find out the mass of gas released. Now that we had collected our data, we used Talons law of partial pressures to calculate the pressure of the gas from the canister alone, so we subtracted the pressure of the water vapor at the recorded water temperature (1 5. ICC) from the total pressure of the gas (763. 0 meg). With the pressure of the unknown gas lone, we were ready to plug our values into the IV=nor equation. Solving for n, we were able to determine how many moles of the gas we had used, so we only had to divide the mass of gas used by the moles to calculate the molar mass of the gas (in grams per mole). With the molar mass of the gas, we were able to identify the gas. 2. Results: Below are the values we recorded for each step in the experiment, as well as the calculations we made to come up with the molar mass of the unknown gas. Thus, the unknown gas was butane, CHICHI, whose molar mass is about 58. G/ mol. 3. Discussion: The theory behind our experiment was to find each necessary factor in the simplest, most accurate way. The most difficult part was figuring out how to catch all of the gas that we released, and to measure the volume of that gas precisely. The method we used was very effective because we were able to see the movement of the gas, and we were therefore able to control its entry into the test tube. Our results were pretty accurate, but there was some room for error. Below are the calculations for the percent error of our molar mass assortment. Some of the sources of error came from possible procedural problems, while others came due to the theoretical limitations of the experiment. One of the procedural difficulties we may have encountered was that there might have still been some water left on the canister when we weighed it the second time. Because the second mass of the canister would have the added mass of the water, the difference between the original mass and the mass after the gas had been released would have been smaller. Thus, we would have recorded a lower ass of gas released, so the molar mass calculation would have been lower because the numerator of the equation would have been smaller. Perhaps we could have blow-dried the canister for a longer period of time until we were absolutely sure that no water remained. Another procedural problem was the balance we used. Because it only measures to the hundredths place, we recorded the mass of the gas released to only one significant figure. Because of this, we were limited to only one significant figure in our calculation of the molar mass, so although we would have had an answer of 52. G/mol, we had to round down to 50 g/mol, which led to a greater percent error. The theoretical difficulties arose because we were applying the ideal gas law to a real gas. So, for example, while ideal gas particles have elasticity and dont lose speed or energy when they collide, the particles of a real gas do lose energy and speed, and this decrease leads to lower pressure. Also, ideal gases do not have any intermolecular forces, and the volume of the particles of an ideal gas can be ignored, but with a real gas, the particle size makes a difference. Because butane molecules are so large ND exist in a state very close to liquid form, we know that there are very strong dispersion forces holding the molecules together. Larger molecules have more momentary dipoles, and thus a stronger attraction, so because the molecules are held so close together, the volume we recorded was smaller than it would have been if butane were an ideal gas. However, despite these errors, our calculated molar mass was not very far from the actual molar mass of butane gas, so we did a relatively good job of controlling these variables that could have greatly affected our results.

Litigation public relations Essay Example | Topics and Well Written Essays - 500 words
Litigation public relations - Essay Example One should remember that litigations against companies are only brought about when there is a strong suspicion of wrong-doing, and the litigation is raised usually by competing companies or the general public. While lawyers can argue that every company has the right to defend itse is lf, PR managers on the other hand usually act out of loyalty as well as their own investments in the company. In this sense, one can see that ethics are not the primary motivation for LPR exercises. As opposed to publishing and reporting the truth as it exists, LPR efforts attempt to color this truth and make it favorable to the company's cause. This might ultimately prove beneficial to the company by reducing negative publicity and consequently not affecting its bottom line, but the general public and the broader industry might suffer due to the misinformation being generated. To be fair to the defendants, one has to concede that media coverage generally tends to be hostile to them. For example, most la w-suits are covered from the viewpoint of the plaintiff or the prosecutor and their case gets presented in greater detail. There is a slight negative bias toward the defendant, for they are deemed as wrong-doers until proven otherwise.

Legal Implications of False Memories in Children Essay
Legal Implications of False Memories in Children - Essay Example 's account matches the other children's testimony Might there be some truth in these testimonies that he judges and lawyers are overlooking Organizations such as the the False Memory Syndrome Foundation have continually stuck to the premise that any memory generated as a result of therapy is based on a lie and should be classified as unintentional lying because the therapist induced it suggested it or guided it. They further state that as part of their training psychiatrists are taught mind control techniques therefore they can implant a memory that was not there and the judges or lawyers would not be able to know the truth when the patient testifies. (Murphy 1997) For most advocates the best defense strategy against these cases is usually to claim the memories of trauma are all in the victims head. With the revelation of this research, defense lawyers can now cite the study. They can then move to file pre-trial motions challenging the reliability of the testimony based on recovered memories hence dismiss its admissibility in court. These motions should be filed early enough so as to dismiss and call for summary judgment. The defense can also seek to offer its own "expert "opinion based on this scientific study to the plaintiff's scientific theories that the brain can avoid or repress traumatic information and remember it later. The defense will further seek to bring forth evidence from published and unpublished studies purporting to demonstrate the existence of "false memory syndrome." And try to justify its existence in that particular child. The defense will also seek to introduce research allegedly showing that the mind can be "implanted" with false memories. Defendants may also try to offer evidence that traumatic events are highly memorable and cannot be repressed. The plaintiff or the Childs legal representative would first seek to crash any motion flied that seeks to scientifically explain the child's state of mind and use it as evidence. Since none of the theories can evaluates and prove a child is capable of repressing memories. Accordingly, the evidence should not be used regardless of scientific reliability because it is irrelevant and cannot assist the jury in coming up with a concrete decision (Bauer 2002). The plaintiff's best approach is to expect this defense strategy and take the first action by filing a motion to exclude the

The Presidency Essay Example | Topics and Well Written Essays - 1000 words - 1
The Presidency - Essay Example He was barely twenty years old when he started out with FBI in this modest fashion. He climbed up the career ladder steadily thereafter. His appointment as the Assistant Special Agent in Charge (ASAC) in Chicago is a notable milestone. But it is the World Trade Center (WTC) bombing at Oklahoma in 1993 that would prove to be a turning point in his career. A year later he was made supervisor of VAPCON in 1994. From this point onwards John was deeply involvement in counter-terror operations for the rest of his life. In hindsight a lot of warnings given by Oââ¬â¢Neill have proven to be right. His fractious relationship with the FBI bosses and his own abrasive personality had created distrust or disregard for the information that he was passing on. Though a lone voice among his colleagues, he kept repeating the threat of terrorist attacks till the very end of his tenure with the FBI. In the last few years of his service, he served as the Chief of Counterterrorism Section within the FBI . Despite this critical position he held within the national intelligence apparatus his words were not given due respect. Every time an important lead would emerge, ââ¬Å"John would fight with Washington to make sure that we constantly took the lead on these investigations. So we would build this intelligence base, and so we would have investigators that had the institutional knowledge and that was the way it was.â⬠(Clint Guenther, Former FBI Agent NYC ââ¬â Counterterrorism) Investigating the 911 terror attacks in retrospect, there is nothing inevitable about its occurrence. There were enough indications for the FBI to take preventative action. John Oââ¬â¢Neill saw himself as the champion of this cause ââ¬â one of saving America from a grave security threat. But, unfortunately, those around him, especially the top leaders in the FBI did not concur with Oââ¬â¢Neillââ¬â¢s views. More than an odd lapse it is a systematic failure on part of the key national agenc y. Bureaucratic bungling and red tape have made Oââ¬â¢Neillââ¬â¢s desperate attempts to communicate a challenge. Personal ego hassles between Oââ¬â¢Neill and his peers and superiors was another mitigating factor. Oââ¬â¢Neillââ¬â¢s abrasive personality rubbed off his colleagues the wrong way. As a result, the intelligence reports given out by Oââ¬â¢Neill did not get the urgent attention that they merited. One needs to ask how personal favoritism and prejudice can undermine the high profile operations of the FBI. John Oââ¬â¢Neill was quite vocal and persistent about the presence of Al Qaeda sleeper cells in the United States. John had communicated how the terror network had developed capabilities for attacking many strategic locations not just in the United States but anywhere in the world. It was Oââ¬â¢Neill who identified Al Qaeda as the foremost threat to America -much ahead of his peers did. As his colleague Richard Clarke recounts, ââ¬Å"I would go around the country to FBI offices and ask, "Is there an Al Qaeda presence in Chicago, in San Francisco, in Boston?" And typically the reaction I would get is, "What's Al Qaeda?"...But not with John. John knew what Al Qaeda was; he was among the first people to see the bin Laden threat. He believed there was a bin Laden network in the United States even if he couldn't prove it. So he was constantly trying to prove itâ⬠¦" (Richard Clarke, NSS Coordinator for Counterterrorism, 1992-2001) John Oââ¬â¢

Agriculture In Deforestation And Desertification Environmental Sciences Essay
Agriculture In Deforestation And Desertification Environmental Sciences Essay The World Resources Institute estimates that more than 50 percent of the earths natural forests have already been destroyed (Hermosilla 2000). The United Nations Environment Programme (2009) states that forests cover 30 per cent of the planets total land area. The total forested area in 2005 was just under 4 billion hectares As a result a United Nations report has stated that deforestation and forest degradation are widely recognized as one of the most critical environmental problems facing human society, with serious long-term economic, social and ecological consequences (UN 1999). The causes of deforestation are widely debated and are attributed to many causes such as over population and urbanisation such as new settlements and transport extensions (Geist and Lambin, 2002). However one of the main causes of deforestation is attributed to agriculture. The arc of deforestation along the southern and eastern extent of the Brazilian Amazon is the most active land-use frontier in the world in terms of total forest loss (Morton et al, 2006) and Globally, the main forest conversion process in the humid tropics was the transformation of closed, open, or fragmented forests to agriculture (Achard et al 2002). Deforestation originally occurred on a small scale level due to subsistence farming or timber collection. However the Amazon rain forest has seen a recent increase in industrial agriculture intensive mechanized agriculture in the Brazilian Amazon grew by >3.6 million hectares during 2001-2004 (Morton et al, 2006) and this has been a significant source of deforestation in recent years. In 2010 cattle are projected to be grazing on some 24million hectares of Neotropical land that was once forest in 2000 (Wassenaar et al, 2006). Figure 1 shows the causes of Amazonian deforestation from 2000- 2005. The pie chart shows that cattle ranching, a part of agriculture is the main cause of deforestation. Cattle ranching accounts for 65-70% of deforestation; vast areas of land are cleared by commercial farmers to raise cattle (for meat and dairy) and to provide pasture land for the cattle to graze. Moreover another major cause of deforestation is small scale agriculture by subsistence farmers. Subsistence farmers are causing deforestation because of poor practices (Butler 2008). Farmers burn the trees to clear them, and then over-exploit the land causing the soil quality to decline which results in the farmers having to find new land (shifting cultivation) and thus destroy more trees. In addition government policies can lead to deforestation. In Brazil the government allows farmers to claim a piece of unclaimed public land which they must use for over a year; and after 5 years they become the official owners of the la nd and so can sell it and claim new land (Butler 2008). In addition population growth and subsequent food demand is also a cause for expanding agriculture. Figure 1. (Butler, 2008) However research has also shown that agriculture is not the main cause or contributor to deforestation. Instead the main cause of deforestation if attributed to population growth, and its subsequent need to find new land for settlements to be built on. Myers, 1984 says that the main reason for deforestation in the tropics is human population growth. In the African and Asian tropics, it is generally associated with high rates of natural increase (i.e., high net rates of population growth due to high fertility) and, in the Amazon, it is assumed to be the high rates of in-migrationà ¢Ã¢â ¬Ã ¦ followed by subsequent intergenerational high rates of natural increase. In addition another primary cause of deforestation, particularly Indonesia is the logging industry. The World Bank (2000) and WRI (2000) state that the leading cause of Indonesian deforestation in the 1990s has been large-scale commercial logging (Palmer 2001). Palmer (2001) continues to say that logging causes areas of forest to be cleared, allowing access to new areas of forest and as a result previously unexploited forest, thus allowing other economic activities such as agricultural conversion and shifting cultivation to take place. Consequently the logging industry can be seen as a major, if not the major contributor to deforestation and not agriculture. Agriculture has been linked to being a cause of desertification, however a variety of other factors are also causes of desertification and a combination or interaction of processes leads to desertification. The United Nations Conference on Environment and Development defines desertification as land degradation in arid, semi-arid, and dry sub-humid areas resulting from various factors, including climatic variations and human activities (UNCCD, 1992) The UNCCD states that Desertification does not refer to the expansion of existing deserts. It occurs because dryland ecosystems, which cover over one third of the worlds land area, are extremely vulnerable to over-exploitation and inappropriate land use. Poverty, political instability, deforestation, overgrazing and bad irrigation practices can all undermine the productivity of the land (UNCCD 2005). Agriculture plays a large role in desertification, the over grazing of land by animals particularly damaging to the soil and is a major factor contributing to desertification; overgrazing is by all measures the principal cause of rangeland degradation (Dregne and Chou, 1992).à Over grazing can occur by having too many animals, or by not managing and controlling the animals grazing activities (Rayburn, 2000). Overgrazing reduces plant leaf areas, which reduces interception of sunlight and plant growth.à Plants become weakened and have reduced root length, and the pasture sod weakensà ¢Ã¢â ¬Ã ¦ Overgrazing can increase soil erosion.à Reduced soil depth, soil organic matter, and soil fertility hurt the lands future productivity (Rayburn 2000). Darkoh (2006) highlights that overgrazing in North Africa has led to the desertification of land led to moderate to severe desertification of rangelands in arid and semiarid zones of Algeria, Libya, Morocco and Tunisia Moreover it is not just overgrazing that can lead to soil degradation and desertification. Poor farming techniques such as over exploitation, and constant crop growing without a fallow field can lead to degradation. Arid and semi-arid regions may initially support agriculture, but repeated cultivation frequently leads to a loss of a soils nutrients and water-holding capacity. (Global environmental Governance Project, 2009). Over cultivation removes nutrients from the soil which can lead to the soil becoming derogated and infertile, therefore nothing can grow on it which can lead to soil erosion. In addition to this, poor irrigation systems can lead to salinzation of the soil due to groundwater dissolving salts in the soil. When evaporation takes place, this leaves concentrated amounts of salts in the soil which are toxic to plants and thus the land becomes barren. However agriculture may not be a direct cause of desertification, it can be caused due to knock on effects of population growth and the subsequent increased demand for food. In Africa, a leading cause of desertification is human population pressure which leads to overexploitation and intensified stresses on the natural environment. Africas population has doubled in the past three decades to about 708 million (1994) and continues to expand at a rate of some 3 per cent a year. This means that Africas farmers must feed an additional 21 million people every year (Darkoh, 1998). Moreover population increase can lead to urbanization and more resources being demanded, such as fuel wood which is a common fuel in third world countries; deforestation is also a primary cause of desertification as tree roots bind the soil together, preventing erosion. As a result population pressure has lead to the need for intensive agriculture which can lead to desertification Increased population pressure on the fragile and vulnerable soils of Africas dryland regions, leads to overexploitation of water, land, forest and pasture resources through over cultivation, overgrazing and deforestation. These practices therefore constitute the principal threats to the livelihood of millions of people. These are the foremost causes of soil erosion, the rates of which in Africa are among the highest in the world. (Darkoh,1998). Agriculture plays a large role in deforestation and desertification, but it may not be the main causes of both. Shifting cultivation leads to deforestation as farmers move to new areas of land, often forests which need to be cut down so that the land can be used for agriculture. In addition over grazing and cultivation as well as as poor farming techniques and can lead to desertification. However the real cause of deforestation and desertification can be attributed to government policies and government mismanagement. If governments encourage farmers to seek out new land in the Amazon rain forest, and also do not stop practices of illegal logging. In addition if governments act in their own economic interests and issue policies that lead to environmental harm such as deforestation and desertification then it is not the practices of its people and their techniques (farmers) that cause the damage to the planet, it is the consequence of poor, and often myopic, government policies seeking economic gain; instead of addressing the real causes of the problems of desertification and deforestation. In addition many LEDCs rely on agriculture for economic growth; therefore a balance needs to be met between economic development and sustainability.

Abstinence :: essays papers
Abstinence With all the emphasis on the importance of using condoms and birth control to ensure safer sex, I feel an intelligent choice is being overlooked. What is this choice? Well, it is sometimes looked at as old-fashion or not as a plausible decision. I feel, though, that it is very possible, and I am living proof that it is. This decision that I have made is pre-marital sexual abstinence. First of all, I want to say that I feel that people should be educated about condoms and other forms of birth control. Being responsible enough to take those measures when dealing with sex is important in and outside marriage. Also, I would like to say that I am not looking down on anyone who chooses to engage in pre-marital sex. Many of my closest friends have chosen to have sex, and I have and always will be there for them no matter what decisions they make. I can talk to them about sex and give advice knowing that their beliefs are not mine. So, why have I made this decision? Well, the root of my decision is from my religion. I am a born-again Christian, and God tells us in the bible that it is wrong to have sex outside of marriage. When I was in junior high, I made a lot of promises that I swore I wouldnââ¬â¢t break. They included such things as not drinking and not having sex until I was married. Well, I managed to break most of those promises in high school, but I always have kept my promise of abstinence. It wasnââ¬â¢t a decision that I made to be a ââ¬Å"goodâ⬠girl, it was a way of life. Every issue I saw that dealt with sex in high school made my decision even stronger. I was scared that me wanting to be a virgin would receive a lot of sarcasm and jokes, but I instead received the exact opposite. Boys that found out would think it was wonderful and say such things as ââ¬Å"Youââ¬â¢re the type of girl I want to marry!â⬠One of my best friends wrote in my yearbook ââ¬Å"I will always admire you for your ability to say no in the most intense, heat of the moment. Always stick to what you believe.
