J.J Thomson Essay Example for Free

J.J Thomson Essay J also had a brother that was two years younger than him-self named, Frederick Vernon Thompson. He went to private schools in the beginning of his education career, where he showed a great interest and passion for science, and when was 14 years old when he was accepted in to Owens College. His mother and father originally wanted him to study to be an engineer and get an apprentice for a local locomotive manufacturer, but due to his father’s death in 1873 his plans changed. He moved away from Owens College, and into Trinity College in Cambridge, where he then obtained his BA in mathematics in 1880. He married one of his students, Rose Elizabeth Paget, and they had one son and one daughter. J. J Thompson died still working on the college campus on August 30th, 1940 from unspecified causes at the age of 83. He married one of his students, Rose Elizabeth Paget, and they had one son and one daughter. J. J Thomson was without a doubt religious. He was a devout Anglican Episcopalian who regularly attended services at the Angelican church, and also went to Sunday evening college chapel services. I believe, that the best statement that I found, about the religious practices of Mr. Thomson was from one of his students, Sir Owen Richardson who said He was sincerely religious, a churchman with a dislike for Anglo-Catholicism, a regular communicant, who every day knelt in private prayer, a habit known only to Lady Thomson until near the end of his life. Further research shows that J. J Thompson never missed a day of prayer(as quoted above) and that every day before going to sleep, he would read his bible. Some of J. J’s speeches, and addresses also show that he was a devout believer in God, show in what he stated in his inaugural presidential address into the British association, As we conquer peak after peak we see in front of us regions full of interest and beauty, but we do not see ur goal, we do not see the horizon; in the distance tower still higher peaks, which will yield to those who ascend them still wider prospects, and deepen the feeling, the truth of which is emphasized by every advance in science, that Great are the Works of the Lord. Here we clearly see, that he doesn’t take credit for his accomplishments, he gives the credit to the Lord.

ADHD and Its Treatments Essay -- ADHD Attention Deficit Essays Disorde

The purpose of this research was to describe and understand Attention-Deficit Hyperactivity Disorder (ADHD) and the most effective treatment options that are available today. ADHD is a mental health disorder that affects 3-9% of the population in ways that, if left untreated, can wreak havoc on the mind of the sufferer. It makes concentration difficult, large tasks seem insurmountable, and causes impulsive and hyperactive tendencies. Fortunately, research and experiments have led to new and effective treatments to help those who suffer from this disorder (Dupaul 8). This research examined journal articles and internet sources on the topic to help unlock the complexities of the disorder through scientific research. It also was a way to separate the myths of the disorder from the truths, while discovering the causes, diagnosis methods, and best treatment alternatives to battle this prevalent disorder.   Ã‚  Ã‚  Ã‚  Ã‚  In 1902, a physician by the name of Sir George F. published a series of lectures to the Royal College of Physicians in England in which he described a group of impulsive children with significant behavioral problems, caused by a genetic dysfunction and not by poor child rearing?children who today would be easily recognized as having ADHD (NIMH 1). Attention-deficit hyperactivity disorder or (ADHD) is a developmental disorder characterized by distractibility, hyperactivity, impulsivity, and an inability to remain focused on tasks or activities. ADHD afflicts an estimated 3-9% of children, with symptoms usually appearing by the age of seven. Some key characteristics of the disorder include a person who: ?  Ã‚  Ã‚  Ã‚  Ã‚  Is easily distracted by events occurring around them ?  Ã‚  Ã‚  Ã‚  Ã‚  Puts off anything that requires a sustained mental effort ?  Ã‚  Ã‚  Ã‚  Ã‚  Appears not to listen when spoken to ?  Ã‚  Ã‚  Ã‚  Ã‚  Shows a repeated failure to finish tasks ?  Ã‚  Ã‚  Ã‚  Ã‚  Has a difficulty staying still ?  Ã‚  Ã‚  Ã‚  Ã‚  Shows difficulty in organizing activities   Ã‚  Ã‚  Ã‚  Ã‚  These symptoms prove to be particularly challenging to children and adolescents. Although they may be quite intelligent, their lack of focus frequently results in poor grades and difficulty in school. Children and adolescents with ADHD tend to act impulsively, without addressing the consequences of their actions until it is too late. Their attention spans are much shorter than most children?s are, thus they become bored easily and frustrated with ... ...performed by the NIMH to support the assertions that genetic disposition and neurobiology were possible causes of ADHD. Their experiment studied 152 boys and girls with ADHD, and matched with 139 age- and gender-matched controls without ADHD. The children?s brains were scanned at least twice, some as many as four times over a decade. From the documentation, this appears to be a reliable experiment because of the gender and age matched control group. 3. Is there an alternative way to interpret the evidence? In my opinion and in my observations in my life, the evidence clearly points to a strong correlation between genetics and a person?s chance of having ADHD. I have also had friends with ADHD whose parents exhibit similar symptoms. 4. What additional studies would help evaluate the alternatives? I think that if genetic and neurobiological studies are conducted, the researcher should randomize the age groups tested, and continue their research as a long-term study. 5. What conclusions are most reasonable? The conclusion drew was that more research needs to be conducted to before drawing an absolute conclusion that genetics and neurobiology determine the patterns of ADHD

Confessions of an Application Reader Essay

A HIGHLY qualified student, with a 3. 95 unweighted grade point average and 2300 on the SAT, was not among the top-ranked engineering applicants to the University of California, Berkeley. He had perfect 800s on his subject tests in math and chemistry, a score of 5 on five Advanced Placement exams, musical talent and, in one of two personal statements, had written a loving tribute to his parents, who had emigrated from India.

Readers’ Comments Readers shared their thoughts on this article. Read All Comments (250)  » Why was he not top-ranked by the â€Å"world’s premier public university,† as Berkeley calls itself? Perhaps others had perfect grades and scores? They did indeed. Were they ranked higher? Not necessarily. What kind of student was ranked higher? Every case is different. The reason our budding engineer was a 2 on a 1-to-5 scale (1 being highest) has to do with Berkeley’s holistic, or comprehensive, review, an admissions policy adopted by most selective colleges and universities. In holistic review, institutions look beyond grades and scores to determine academic potential, drive and leadership abilities. Apparently, our Indian-American student needed more extracurricular activities and engineering awards to be ranked a 1. Now consider a second engineering applicant, a Mexican-American student with a moving, well-written essay but a 3. 4 G. P. A. and SATs below 1800. His school offered no A. P. He competed in track when not at his after-school job, working the fields with his parents. His score? 2. 5. Both students were among â€Å"typical† applicants used as norms to train application readers like myself. And their different credentials yet remarkably close rankings illustrate the challenges, the ambiguities and the agenda of admissions at a major public research university in a post-affirmative-action world. WHILE teaching ethics at the University of San Francisco, I signed on as an â€Å"external reader† at Berkeley for the fall 2011 admissions cycle. I was one of about 70 outside readers — some high school counselors, some private admissions consultants — who helped rank the nearly 53,000 applications that year, giving each about eight minutes of attention. An applicant scoring a 4 or 5 was probably going to be disappointed; a 3 might be deferred to a January entry; students with a 1, 2 or 2. 5 went to the top of the pile, but that didn’t mean they were in. Berkeley might accept 21 percent of freshman applicants over all but only 12 percent in engineering. My job was to help sort the pool. We were to assess each piece of information — grades, courses, standardized test scores, activities, leadership potential and character — in an additive fashion, looking for ways to advance the student to the next level, as opposed to counting any factor as a negative. External readers are only the first read. Every one of our applications was scored by an experienced lead reader before being passed on to an inner committee of admissions officers for the selection phase. My new position required two days of intensive training at the Berkeley Alumni House as well as eight three-hour norming sessions. There, we practiced ranking under the supervision of lead readers and admissions officers to ensure our decisions conformed to the criteria outlined by the admissions office, with the intent of giving applicants as close to equal treatment as possible. The process, however, turned out very differently. In principle, a broader examination of candidates is a great idea; some might say it is an ethical imperative to look at the â€Å"bigger picture† of an applicant’s life, as our mission was described. Considering the bigger picture has aided Berkeley’s pursuit of diversity after Proposition 209, which in 1996 amended California’s constitution to prohibit consideration of race, ethnicity or gender in admissions to public institutions. In Fisher v.  the University of Texas, the Supreme Court, too, endorsed race-neutral processes aimed at promoting educational diversity and, on throwing the case back to lower courts, challenged public institutions to justify race as a factor in the holistic process. In practice, holistic admissions raises many questions about who gets selected, how and why. I could see the fundamental unevenness in this process both in the norming Webinars and when alone in a dark room at home with my Berkeley-issued netbook, reading assigned applications away from enormously curious family members. First and foremost, the process is confusingly subjective, despite all the objective criteria I was trained to examine. In norming sessions, I remember how lead readers would raise a candidate’s ranking because he or she â€Å"helped build the class. † I never quite grasped how to build a class of freshmen from California — the priority, it was explained in the first day’s pep talk — while seeming to prize the high-paying out-of-state students who are so attractive during times of a growing budget gap. (A special team handled international applications. ) In one norming session, puzzled readers questioned why a student who resembled a throng of applicants and had only a 3. 5 G. P. A. should rank so highly. Could it be because he was a nonresident and had wealthy parents? (He had taken one of the expensive volunteer trips to Africa that we were told should not impress us. ) Income, an optional item on the application, would appear on the very first screen we saw, along with applicant name, address and family information. We also saw the high school’s state performance ranking. All this can be revealing. Admissions officials were careful not to mention gender, ethnicity and race during our training sessions. Norming examples were our guide. Privately, I asked an officer point-blank: â€Å"What are we doing about race? † She nodded sympathetically at my confusion but warned that it would be illegal to consider: we’re looking at — again, that phrase — the â€Å"bigger picture† of the applicant’s life. After the next training session, when I asked about an Asian student who I thought was a 2 but had only received a 3, the officer noted: â€Å"Oh, you’ll get a lot of them. † She said the same when I asked why a low-income student with top grades and scores, and who had served in the Israeli army, was a 3. Which them? I had wondered. Did she mean I’d see a lot of 4. 0 G. P. A. ’s, or a lot of applicants whose bigger picture would fail to advance them, or a lot of Jewish and Asian applicants (Berkeley is 43 percent Asian, 11 percent Latino and 3 percent black)? The idea behind multiple readers is to prevent any single reader from making an outlier decision. And some of the rankings I gave actual applicants were overturned up the reading hierarchy. I received an e-mail from the assistant director suggesting I was not with the program: â€Å"You’ve got 15 outlier, which is quite a lot. Mainly you gave 4’s and the final scores were 2’s and 2. 5’s. † As I continued reading, I should keep an eye on the â€Å"percentile report on the e-viewer† and adjust my rankings accordingly. In a second e-mail, I was told I needed more 1’s and referrals. A referral is a flag that a student’s grades and scores do not make the cut but the application merits a special read because of â€Å"stressors† — socioeconomic disadvantages that admissions offices can use to increase diversity. Officially, like all readers, I was to exclude minority background from my consideration. I was simply to notice whether the student came from a non-English-speaking household. I was not told what to do with this information — except that it may be a stressor if the personal statement revealed the student was having trouble adjusting to coursework in English. In such a case, I could refer the applicant for a special read. Why did I hear so many times from the assistant director? I think I got lost in the unspoken directives. Some things can’t be spelled out, but they have to be known. Application readers must simply pick it up by osmosis, so that the process of detecting objective factors of disadvantage becomes tricky. It’s an extreme version of the American non-conversation about race. I scoured applications for stressors. To better understand stressors, I was trained to look for the â€Å"helpful† personal statement that elevates a candidate. Here I encountered through-the-looking-glass moments: an inspiring account of achievements may be less â€Å"helpful† than a report of the hardships that prevented the student from achieving better grades, test scores and honors. Should I value consistent excellence or better results at the end of a personal struggle? I applied both, depending on race. An underrepresented minority could be the phoenix, I decided. We were not to hold a lack of Advanced Placement courses against applicants. Highest attention was to be paid to the unweighted G. P. A. , as schools in low-income neighborhoods may not offer A. P. courses, which are given more weight in G. P. A. calculation. Yet readers also want to know if a student has taken challenging courses, and will consider A. P. ’s along with key college-prep subjects, known as a-g courses, required by the U. C. system. Even such objective information was open to interpretation. During training Webinars, we argued over transcripts. I scribbled this exchange in my notes: A reader ranks an applicant low because she sees an â€Å"overcount† in the student’s a-g courses. She thinks the courses were miscounted or perhaps counted higher than they should have been. Another reader sees an undercount and charges the first reader with â€Å"trying to cut this girl down. † The lead reader corrects: â€Å"We’re not here to cut down a student. † We’re here to find factors that advance the student to a higher ranking. Another reader thinks the student is â€Å"good† but we have so many of â€Å"these kids. † She doesn’t see any leadership beyond the student’s own projects. Listening to these conversations, I had to wonder exactly how elite institutions define leadership. I was supposed to find this major criterion holistically in the application. Some students took leadership courses. Most often, it was demonstrated in extracurricular activities.

Grand Challenges Memories For Life - 2653 Words

Grand Challenges 3 Memories for life Final Version Wei Dong ID: 4830593 29 April 2015 Created the first version: 25 April. Second Edition finished: 29 April Third Edition finished: 30 April Abstract In this article, one of the grand challenges – memories for life is discussed. When the topic â€Å"memories for life† was first mentioned? Who mentioned it? What was the module for that challenge? What fields are related to this grand challenge? In this article, I pick out seven areas from computer science to talk about the questions and problems, and if available, what should we do in the future. Of course, that’s not complete solution, but we can discuss what effect should be done now or in the future. Then, I offer an example about OpenCV to illustrate what we can do on object identification and image processing in computer vision field based on today’s computing technologies. However, if we want to make challenges into real life, we still have too much research and study to do. The purpose of this white paper is to illustrate one grand challenge—memories for life, and talk about possible solution base on today’s technology.
