...participants were given a questionnaire which asked them to describe the accident and then answer a series of specific questions about it. There was one critical. This question was ‘About how fast were the cars going when they hit each other?’ One group of participants were given this question. The other five groups were given the verbs smashed, collided, bumped or contacted in place of the word hit. The mean speed estimate was calculated for each group. The group given the word ‘smashed’ estimated a higher speed than the other groups (about 41 mph). The group given the word ‘contacted’ estimated the lowest speed (about 30 mph). This suggests that memory is easily distorted by questioning technique and information acquired after the event can merge with original memory causing inaccurate memory. This may not be valid because the participants may not have taken the task seriously as they knew it was not real (lacks ecological validity) and there was little to no consent given by participants to watch clips on car crashes so could cause psychological harm. However since it was a lab experiment it is easy to replicate as it’s controlled. Loftus and Palmer also conducted another study in which participants were shown a series of slides of a customer in a restaurant. In one version the customer was holding a gun, in the other the same customer held a checkbook. Participants who saw...

...ECEN 1400 - Introduction to Digital and Analog Electronics Peter Mathys, Spring 2013 Lab 5: Inductors and How to Light White LEDs from 1 Volt Quick Links * Goals of this Lab * Prelab * Lab Experiments Goals of this Lab * Wind a toroidal inductor. * Measure the inductance and the resistance of an inductor. * Use an inductor to step up the voltage of a battery. * Build a circuit for lighting up white LEDs from a 1 Volt battery. This lab is a group activity. The current group assignments are given here. One lab report per group needs to be turned in on D2L. The responsibilites for the successful completion of the lab consist of three parts: The prelab, the actual lab measurements, and the writing of the report. The report will be graded according to three criteria: Correctness, completion, and clarity. On the cover page you must clearly state which group member had the main responsibility for the prelab, for the lab measurements, and for the report writing. All group members need to be knowledgeable for all three parts, but each member has a specific role in the group. The responsibilities must be rotated for future labs so that each group member will have experienced all three roles. Prelab An inductor is a passive device that can store energy in its magnetic field. Two examples of inductors (solenoid on the left, toroid on the right) are shown in the figure below. The i-v relationship for an inductor is: Compare this to the i-v...

...* Liana Cornacchio * PSY Lab B11 * November 15, 2012 * Lab Report 1, Lab 5: Memory Introduction/Hypothesis * In this study we are putting Baddeley’s Model of Working Memory to test to see if working memory is in fact divided into parts three parts: the visuospatial sketchpad, central executive, and the phonological loop. Baddeley believes that the loop and the sketchpad do not interact; we formed a similar hypothesis. Working memory has separate systems for sound/verbal information and visual/spatial information. We hypothesized that there was no interaction between the phonological loop and the visuospatial sketchpad, like Baddeley. So, the phonological distracter would more negatively impact the participants’ performance on the phonological task than the visuospatial distracter and vice versa. Methods * The participants of this study were random volunteers from Psy Lab section B11, the lab in which the study took place. The age range was 18-20 years old and there were 3 males and 3 females that took part in the study. To conduct this study Microsoft PowerPoint was used to create slideshows for the different situations described below. The Internet was also used for the distracters. To record the data we found we used Microsoft Excel as well as pen and paper. For the tasks that required the use of a timing apparatus, we used an iPhone stopwatch. To ensure there was no subject biases we used a Latin square to decide the order in which each individual...

She's offering to sell the old lightbulb, which has been touched by an angel. It was the black angel, if that sweetens the pot for anyone. If you're interested, contact Old Woman Josie. She's out near the car lot. A new man came into town today. Who is he? What does he want from us? Why his perfect and beautiful haircut? Why his perfect and beautiful coat? He says he is a scientist. Well, we have all been scientists and one point or another in our lives. But why now? Why here? And just what does he plan to do with all those breakers and humming electrical instruments in that lab he is renting—the one next to Big Rico's Pizza? No one does a slice like Big Rico. No one. Just a reminder to all the parents out there. Let's talk about safety when taking your children out to play in the Scrub Lands and the Sand Wastes. You need to give them plenty of water, make sure there's a shade tree in the area, and keep an eye on the helicopter colors. Are the unmarked helicopters circling the area black? Probably World Government. Not a good area for play that day. Are they blue? That's the Sheriff's Secret Police. They'll keep a good eye on your kids, and hardly ever take one. Are they painted with complex murals depicting birds of prey diving? No one knows what those helicopters are, or what they want. Do not play in the area....

...Information passes from store to store in a linear way. Both STM and LTM are unitary stores. Sensory memory is the information you get from your sense, your eyes and ears. When attention is paid to something in the environment it is then converted to short-term memory. If any information is not important then it decays or disappears. Once in the short term memory informed can be rehearsed and some information is rehearsed and then passed into long term memory. Each store has its own characteristics in terms of encoding, capacity and duration. Encoding is the way information is changed so that it can be stored in the memory. There are three main ways in which information can be encoded (changed): 1. Visual (picture), 2. Acoustic (sound), 3. Semantic (meaning). Capacity concerns how much information can be stored. Duration refers to the period of time information can last in the memory stores. Sensory Register • Duration: ¼ to ½ second • Capacity: all sensory experience (v. larger capacity) • Encoding: sense specific (e.g. different stores for each sense) Short Term Memory • Duration: 0-18 seconds • Capacity: 7 +/- 2 items • Encoding: mainly acoustic Long Term Memory • Duration: Unlimited • Capacity: Unlimited • Encoding: Mainly semantic (but can be visual and acoustic) AO3 One strength of the multistore model is that is gives us a good understanding of the structure and process of the STM. This is good because this allows researchers to expand...

...have medical names and harmless for some (MacGill, 2015). Tachycardia refers to the heart beating too fast at rest being over 100 beats per minute and Bradycardia refers to the heart beating too slow, usually below 60 beats per minute ( MacGill, 2015). The nervous system monitors the body and signals your heart to beat faster in response to increased activity. The normal heart rate undergoes healthy variation, going up in response to some conditions, including exercise, body temperature, body position, and emotion (MacGill, 2015). The blood is rushing around the heart to get rid of deoxygenated blood and carries back oxygenated blood from the lungs (Saladin, 2015) Sounds heard in the cardiovascular system result from the turbulent blood flow (Marieb, 2007). Two sounds can be heard during each cardiac cycle; these sounds are commonly known as "lub" and "dub". The sequence is designated as lub-dub pause, lub-dub pause, and so on (Marieb, 2007). The atrium and ventricle valves open by force circulating the blood going around the body. As your heart pumps blood through your body, you can feel a pulsing in some of the blood vessels close to the skin's surface, such as in your wrist, neck, or upper arm (American, 2014). Counting your pulse rate is a simple way to find out how fast your heart is beating (American, 2014). The time taken to recover is the amount of time it takes a person’s heart rate to go back to its resting rate. It has been predicted that the more energy used by a person...

...Case Study James Morasco College of Southern Nevada – Nursing 211 Clinical Professor Judith Alewel, MSN, RN October 15, 2012 Introduction AV is a 57 year old male whom presented to the Emergency Department of Valley Hospital Medical Center in Las Vegas, NV on September 7, 2012 with the classic signs and symptoms of a left-sided middle cerebral artery (MCA) infarct and was admitted to the medical intensive care unit (MICU). These signs included left sided facial drooping, non-reactive left pupil, right sided weakness in the upper and lower extremities, and the inability to speak. Along with the signs and symptoms of the stroke, a 12-lead EKG revealed that he also has atrial fibrillation. The initial computerized tomography (CT) scan of his brain revealed nothing, but a subsequent MRA (magnetic resonance angiogram) concluded that he did, in fact, have an occluded branch of the left MCA that eventually converted to become hemorrhagic and he was admitted to the MICU. The MRA also found a persistent left trigeminal artery, which is insignificant to his presenting disease process. Along with all of this, a two dimensional echocardiogram revealed some significant hearts problems that will be discussed later. I cared for this patient during the clinical shift on September 18, 2012. History and Physical The only history and physical that was available in this patient’s chart was some narrative comments from his daughter notated by the physician, and this is most likely due to...

It examines its early efforts at developing a competitive product in the domestic market, its globalization strategies, and some of the key challenges it faces today. The paper provide insights into how a late-comer to an industry can overcome certain disadvantages and successfully position itself as a widely respected and successful brand. JEL classification: L 63, M10 Key words: Samsung, mobile phone, strategy ∗ MBA student, KDI School of Public Policy and Management Professor, KDI School of Public Policy and Management ∗∗ I. Introduction For Samsung Electronics, 2003 was a watershed year. It successfully positioned itself as one of the world’s best mobile phone manufacturers and its products were featured all over the media. Many were calling its mobile phones as “the best gift for Christmas”1 or “the Mercedes of mobile phones.”2 Samsung’s achievements were particularly remarkable considering that its primary focus had previously been in semiconductors and home appliances. Indeed, when it first made the decision to enter the mobile phone business, industry observers viewed the move as foolhardy and reckless. But, much to their surprise, Samsung’s foray into the market turned out to be a great success, contributing...

...an assassin's bullets as his motorcade wound through Dallas, Texas. Kennedy was the youngest man elected President; he was the youngest to die. Here is some more in depth research on the conspiracy of his assassination 1976, the US Senate ordered a fresh inquiry into the assassination of John F Kennedy, who was murdered in 1963 during a motorcade in Dallas, Texas. People who had been involved in the original Warren Commission investigations were asked to make fresh statements. The FBI and the CIA were persuaded to release more of their documents on Oswald. New lines of inquiry were opened and individuals who had not previously given evidence were persuaded to come forward. Most important of all, pieces of evidence such as photos and sound recordings were subjected to scientific analysis using the most up-to-date methods and equipment. The House Select Committee on Assassinations (HSCA) completed their investigation in 1979 and they finally came to a discrete verdict that Lee Harvey Oswald fired three shots at Kennedy, one of which killed the president. The fourth shot was fired from the grassy knoll. They concluded that John Kennedy was assassinated as a result of a conspiracy. There are many reasons why the HSCA came to this verdict, but firstly it...
