Fraternitys essays

Fraternitys essays Hummer, Robert and Patricia Yancey Martin. Fraternities and Rape on Campus. Gender and Society December 1989: 457-473. The goal of this research was to analyze the group and organization practices that create in fraternities an abusive social context for women (Hummer 1989). Hummer and Martin examined fraternity dynamics associated with a main focus on rape and sexual coercion of women in fraternities. The researchers work centers on a case study of an alleged gang rape at Florida State University. They claim fraternities are not only the physical context, but also the social and cultural context that encourages the sexual coercion of women. The research implicates that fraternities create The gang rape involved four men and one eighteen year old girl. When the victim was discovered her blood alcohol content was .349. She had crude words and symbols on her thighs. The group rape took place on the third floor of a fraternity house. Hummer and Martin collected data by speaking with law enforcement officials. They also analyzed newspaper articles, conducted open-ended interviews with judges, public attorneys and many people regarding the processing of sexual assault cases. The data that was collected showed that fraternity members are mainly concerned with their masculinity. The researchers portray fraternity members as being dominant, competitive, drinking alcohol and treating women as sexual objects. For some reason not all women seem to care, they even help attract new members to these fraternities. When new members see these women they think that if they are part of this fraternity that they will have sex with them. These women, are called the little sisters, they cant be too confident with themselves to get into positions dealing with fraternities. The strategy that researchers have discovered is the individual strategy; that includes ...

The Different Parts of a Stream

The Different Parts of a Stream A stream is any body of running water that occupies a channel. It is normally above ground, eroding the land that it flows over and depositing sediment as it travels. A stream can, however, be located underground or even underneath a glacier.   While most of us speak of rivers, geoscientists tend to call everything a stream. The boundary between the two can get a little blurry, but in general, a  river  is a large surface stream. It is made up of many smaller rivers or streams. Streams smaller than rivers, roughly in order of size, may be called branches or forks, creeks, brooks, runnels, and rivulets. The very smallest kind of stream, just a trickle, is a rill. Characteristics of Streams Streams may be permanent or intermittent- occurring only part of the time. So you could say that the most important part of a stream is its channel or streambed, the natural passage or depression in the ground that holds the water. The channel is always there even if no water is running in it. The deepest part of the channel, the route taken by the last (or first) bit of water, is called the thalweg (TALL-vegg, from the German for valley way). The sides of the channel, along the edges of the stream, are its banks. A stream channel has a right bank and a left bank: you tell which is which by looking downstream. Stream channels have four different channel patterns, the shapes they show when viewed from above or on a map. The curviness of a channel is measured by its sinuosity, which is the ratio between the length of the thalweg and the distance downstream along the stream valley. Straight channels are linear or nearly so, with a sinuosity of nearly 1. Sinuous channels curve back and forth. Meandering channels curve very strongly, with a sinuosity of 1.5 or more (although sources differ on the exact number). Braided channels split and rejoin, like the braids in hair or a rope. The top end of a stream, where its flow begins, is its source. The bottom end is its mouth. In between, the stream flows through its main course or trunk. Streams gain their water through runoff, the combined input of water from the surface and subsurface. Understanding Stream Order Most streams are tributaries, meaning that they drain into other streams. An important concept in hydrology is stream order. A streams order is determined by the number of tributaries that flow into it.  First-order streams have no tributaries. Two first-order streams combine to make a second-order stream; two second-order streams combine to make a third-order stream, and so on.   For context, the Amazon River is a 12th order stream, the Nile an 11th, the Mississippi a tenth and the Ohio an eighth.   Together, the first through third-order tributaries making up the source of a river are known as its headwaters. These make up approximately 80% of all of the streams on Earth. Many large rivers divide as they near their mouths; those streams are distributaries. A river that meets the sea or a large lake may form a delta at its mouth: a triangle-shaped area of sediment with distributaries flowing across it. The area of water around a river mouth where seawater mixes with freshwater is called an estuary. Land Around a Stream The land around a stream is a valley. Valleys come in all sizes and have a variety of names, just like streams. The smallest streams, rills, run in tiny channels also called rills. Rivulets and runnels run in gullies. Brooks and creeks run in washes or ravines or arroyos or gulches as well as small valleys with other names. Rivers (large streams) have proper valleys, which may range from canyons to enormous flat lands like the Mississippi River Valley. The larger, deeper valleys are usually v-shaped. The depth and steepness of a river valley depends on the size, slope, and speed of the river as well as composition of the bedrock.   Edited by Brooks Mitchell

SMART CHOICES by John Hammond Essay Example | Topics and Well Written Essays - 1500 words

SMART CHOICES by John Hammond - Essay Example He lives in Belmont, Massachusetts and is extensively popular as one of the initiators of the decision sciences field. In this book â€Å"smart choices† from the three leading consultants on decision-making, readers get to understand how to approach each and every type of decisions with a set of elementary skills developed by professors from the University of Southern California, MIT and Harvard. In Smart Choices, the authors offer a systematic approach to making the correct choices. They guide people how to be confident and consistent to decisions they make. For example, choosing which job offer to accept, selecting a fantastic book to read to buying the right vehicle. This user-friendly guide demonstrates to readers how to create a complete set of alternatives, assess deep-seated objectives, grapple with uncertainty, determine likely consequences, and make tradeoffs. Not only will the readers understand how to make good decisions, they will understand and learn how to come u p with smartest decisions. For any individual caught at a confusing situation, the Smart Choices program improves abilities of decision-making and makes one’s life more fulfilling and rewarding. The three authors claim that making smart choices is an essential life skill, which can be trained. They provide a realistic model for making decisions, and show that it is applicable in both business and personal situations. They demonstrate that the solution is to break down the decision into its individual essentials, identifying those that are most significant, and analyzing potential outcomes. These authors also argue that decisions should be made before turning into problems. Their so-called PROACT (Problem, Objectives, Alternatives, Consequences and Trade-offs) approach can be broken down precisely. I.e. Identifying the Problem, specifying the Objectives, creating Alternatives, understanding the Consequences, and weighing the Trade-offs. By following these crucial steps, an ind ividual must shed light on uncertainty, evaluate risks, and be sentient of what other alternatives a decision might produce. Smart Choices summarizes eight useful elements in making the correct decision, from identifying what exactly the decision is and identifying the objectives to considering risk, tolerance and also looking at what one decides on today influences what he/she may decide in the days to come. The book is complete with real-life situations that effectively demonstrate each element of an excellent decision. The general idea of Smart Choices is that excellent decision making comes about through scrupulous planning and thoughtfulness. In chapter one of this book from the three leading professors on decision making, some decisions are fairly obvious. For example, will you step in for your employer for two weeks while he/she attends an educational development course? Definitely it is yes, or one’s bank account is running low, but he/she has a three-week break comin g up and wants to get away to somewhere warm to relax with his/her family. Some of the essential decisions one faces in life are complex and tough, with no obvious or easy solutions, which will not probably affect an individual alone, but also affect his/her family, friends, coworkers and several others both known and unknown. Coming up with compelling decisions is therefore, one of the most significant determinants of how smart someone meets his/her responsibilities and achieve professional and

Managing Projects Essay Example | Topics and Well Written Essays - 2250 words

Managing Projects - Essay Example The Ashleigh Music Festival Company has been tasked with the responsibility of managing this project and ensuring that it is successful. This essay will discuss how the Ashleigh Music Festival as a major project can be executed so as to successfully organize and execute it. This essay will also discuss the key issues of the Ashleigh Music Festival project such as the key tasks to be completed so that the festival can be ready for opening, the importance of using project management skills and techniques and the skills and competencies required of the project team among others. Part B: The importance of Project management tools The Ashleigh Music Festival is an important event the needs to be properly managed so as to ensure that it is successful. Effective project management techniques and processes need to be applied to this project for a number of reasons. These project management techniques and processes may include the creation of a business case, defining the scope of the project , being clear about the goals and objectives that need to be achieved by the project, coming up with a viable project plan and selecting the best project team to execute the project (Archibald 1992). The first reason why it would be important to use these project management techniques and processes in the Ashleigh Music Festival is because the project management team will be provided with the opportunity to take charge of the available resources so as to ensure that the team produces the highest quality deliverables that are on time and within the set budget (Bradford, Duncan & Tarcy 2000). This is much easier when project management techniques and processes are used to plan and execute a project (Cleland 1994). The second reason why it would be important to use project management techniques and processes in the Ashleigh Music Festival is to ensure that all set deadlines for the project are met and that all the necessary actions have a timeline at which they should be executed and a chieved (Burt, Dobler & Starling 2003). When project management techniques and processes are applied, deadlines for each action are given. This means that all the actions will have a timeline during which they should be carried out and completed successfully (Cleland & Gareis 2006). This increases the chances of the entire project succeeding as opposed to when there are no set deadlines. Defining the scope of the project is important because it will help the project to focus on what it is set to achieve, and nothing else. It will enable the project team to remain on course and focus their attention on only what the project is set to achieve. Producing a project plan will outline all the processes that need to be conducted and show how they shall be executed. The plan will act as a guide for all the actions that take place during the project’s life cycle. Getting the right team together is also one of the most important factors that will determine whether the project is succes sful or not. The project team is the heart of the project because it is responsible for planning for it and executing it. Creating a business case is necessary because it will provide a solution to the problems likely to be experienced in the project. Essentially, project management entails a number of processes and standard control systems that will ensure the success of projects like the Ashleigh Music

Good V. Evil Essay Example for Free

Good V. Evil Essay The Strange case of Dr. Jekyll and Mr. Hyde represents a conflict between good and evil. One character (Jekyll) is determined to keep his impulses in check and ignore temptations, while the other character, Mr. Hyde, is brazen and submits to any temptation or impulse. The four main characters in the story are all men of similar social class who are capable of keeping their impulses in check and denying the temptations of evil. In the case of Dr. Jekyll however, Dr. Jekyll is not able to say no to the evils and uses an alternate identity to unleash the monster from within. The story of Dr. Jekyll and Mr. Hyde can be easily related to the reader, as everybody knows the temptations of evil and the pleasures that both good and evil can bring somebody. Dr. Jekyll experiences strong tendencies of both good and bad. Unlike most men of Dr. Jekylls age and geography, Jekyll cannot keep himself from indulging in the pleasures that the evil side can provide. Jekylls trip into extreme evil (Mr. Hyde) is partially due to the fact that he has lived such an acceptable and exemplinary life in the past and he holds himself to a higher standard than some of his collegues. Robert Louise Stevenson describes Dr, Jekyll as a man who his friends were those of his own blood or those whom he had known the longest. (Ch1. P2) Dr. Jekyll seems to only trust those whom he was most comfortable with and does not let people that he barely knows too close into his life. It is possible that Dr. Jekyll did not reach out and become friends with too many people because he was aware of the evilness that was lurking inside of him. The attitude of Dr. Jekyll is described in the opening paragraph as at friendly meetings and when the wine was to his taste, something eminently human beaconed from his eyeStevenson. Could it be possible that Dr. Jekyll was aware of the evil secret life that he hides from the real world? It appears that there was something a little strange about Dr. Jeykll that others couldnt exactly figure out yet. Mr. Enfield is asked by Mr. Utterson to describe Dr. Jekyll so Enfield describes Jekyll as somebody who I never saw a man I so disliked. he gives a strong feeling of deformity, although I couldnt specify the pointStevenson,pg. 1680. The bad side of Dr. Jekyll is evident just by his demeanor although it is nothing compared to the evilness of Mr. Hyde. Mr. Hyde represents the dark side of Dr, Jekyll. Hyde only comes to life when Jekyll takes the drug that brings him out. The drug that unleashes Hyde at first makes Jekyll feel terribly sick but shortly after, Jekyll feels incredible and almost as though he is not human. Jekylls evil fantasies and impulses become a reality after he takes the drug. The drug makes Jekyll feel like he is a whole different person and that allows him to do whatever evil things he wants to do. The good in Jekyll is only returned if he takes an antidote. Just like many other people there is a constant struggle between good and evil of our everyday lives. People who struggle with drugs or alcohol or any other worldly temptations live a similar life to the one that Dr. Jekyll lives. Life is not easy for anybody and sometimes people need to escape their reality for a little while by taking a drug just like Jekyll does. Stevenson does well in creating a parallel between good and evil that people can relate to in their everyday lives. Stevensons story is very similar to a modern film called Limitless staring Bradley Cooper. In Limitless, Cooper, a young man struggling to pay his bills, tries a new drug that gives him extreme brain power which he uses to achieve great wealth and success. The success is only attainable with the use of the drug and without the drug, Cooper becomes sick and very weak, similar to what happens with Dr. Jekyll when he is without the drug. Just like Jekyll, Coopers health starts to dwindle as the supply of drugs becomes smaller and smaller. Stevenson is perhaps trying to teach the reader a valuable lesson in saying no to the temptations of evil. These temptations can often be difficult to ignore. Stevnson seems to suggest the Dr. Jekyll is the victim of a split personality disorder which was a new concept during the Victorian age. The only difference between Dr. Jekylls condition and a split personality disorder is that in the case of somebody suffering from split personalities, the person is aware of the other personality and can bring this person out willfully. Mr. Hyde however, cannot control Jekylls personalty and is not even aware of him. Dr. Jekyll is aware of Mr, Hyde though and understands the evilness that Mr. Hyde causes when Jekyll loses control and takes the drug too much. Mr. Hyde begins to take complete control Stvenson might be suggesting that even if a person is good, once they give into their evil tendencies there is no trunigng back. When Dr. Jekyll starts to flirt with hs bad sidem he begins to lose control of his personality and he eventually loses his friends and good nature. Stevnson displays the power of good will and the consewuences of even the first approach at evil. Once somebody is indulged into a bad habit, they can let their abad habit take control of their lives and it becomes extremely difficult to come back from the evilness once it has become a major part of your life. Dr. Jekyll says, with every day and from both sides of my intelligence, the moral and intellectual, I thus drew steadily nearer to the truthby whose partial discovery I have been doomed to such a dreadful shipwreck: that man is not truly one, but truly two Stevenson. Jekyll is describing the affects of his choices and how he is now truning into his bad side for good because that is the person that he has become. Stevensons main goal in writing this story is to create horror and excitement for the reader. He leaves the reader to draw their own conclusions about the message in the story but it is clear to me that this story is about human nature and the batte of good vs. evil. Once a human gives into their temtations they are more likely to indulge in these evil deeds again and again. Dr. Jekyll tried a drug that made him into a different person and he enjoye giving into his evil tendencies. Eventually these evil tendencies took control over Jekyll and he became too evil to return to the good natured Dr. the his colleagues knew.

Hamlet: Nature of Truth Essay -- GCSE Coursework Shakespeare Hamlet

Hamlet:   Nature of Truth Hamlet  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   To some, truth is something that is absolute and unchanging. To others, truth is volatile and inconstant. In the 16th and 17th century, the foundations of civilization itself had been shaken. Many of the ideas which were thought to be absolutely true had been plunged into the depths of uncertainty. The cosmological, geographical, and religious revolutions called into question the nature of truth itself. It is no wonder, then, that some of the great writers at the time included within their works a treatise on the ways in which truth is constructed. Because of the major ideological revolutions that shaped his world Shakespeare used characters and theatrical devices to create their own ideas on the construction of truth. Shakespeare agrees that each individual must search for his or her conception of the truth, based upon our his or her current knowledge, but he uses the limitations of the stage itself to demonstrate this idea. When Ophelia dies at the end of Act IV, Gertrude gives Laertes a vivid description of Ophelia's death, but this death is never acted on stage. We never know for sure whether Gertrude is telling the truth, and if she was a witness to the death, why she didn't try to save Ophelia. The fact that we only hear about the death calls into question the validity of the transmission of knowledge from one person to another, suggesting that truth itself is not something that one will always learn from another, but something that one must find by oneself. Shakespeare further complicates the truth in Hamlet with the many unanswered questions he leaves us with. We don't know for sure if the ghost is truly good or e... ...d by the rest of history. The revolution of thought that occurred in the 16th and 17th centuries forced Shakespeare and other authors to change the foundations of their own thought. They were all willing to present to us their own ideology of truth so that we may benefit from their knowledge. Everyone faces these crises in life, the crisis of one's own opinions being shattered by reality. We may hold on to our opinions, disregarding fact or twisting the facts to fit our theories. But in order for progress to occur, we must at times shed our previous beliefs in favor of ones newly created. We must endeavor to find a version of the truth that is based in knowledge, and one that satisfies our desires. We may never find a version of truth that is satisfactory for everyone. But our search cannot cease. The truth, after all, is in the eye of the beholder.      

Drama: A road to heaven

As I entered the auditorium to join the rest of the audience, I noticed the set stage, afraid that the play has began, I soon realised that it was set up like that for a purpose. This gave a very new impact to me and made you wonder what the production was going to be about. It also thought me that the beginning of the play does not have to begin with closed curtains or a frozen image. It gave it a very good way of introducing the play. Although the nurses sitting on the stage gave me a good perception of where the play was going to take place. The play was a musical, and it was portrayed in different styles of music and introduced in a variety of ways such as costumes, which showed creativeness and imagination for the scenes. The costumes allowed humour to be created and helped the song and the message that they were trying to get across. The music surprisingly were songs that can be recognised by any generation as they used the unforgettable and loved tunes of any age and they were altered to combine with the musical and characters of the play. The lighting helped the atmosphere and surrounding of the scene it helped us to focus on particular characters and the musicians were always seen as they had particular lighting in order for them to see the instructions. Musicians were not hidden and were visual to the audience at all times. This however did not affect the play. It was very helpful for us drama students, as we have never been introduced in a play where they were exposed musicians and it gave me an interesting perception and I was amazingly surprised by the fact that such a small orchestra composed and produced such wonderful and powerful music. I noticed throughout the scene how there was a young male nurse who helped with the characters' costumes and props. I believe that the purpose of him being in the scene dressed up as a nurse is to show us the constant of him helping the cast in the play itself and playing the role of a nurse n the story. The music conductor of the small orchestra spoke to the audience on behalf of the cast, he also helped the cast with their timing of the singing and the time they were going to actually sing this exposed his role with the orchestra and the play. The play was very enjoyable to watch and thought me many techniques and gave me a wide range of ideas. The characters were extremely entertaining to watch and I liked the use of music and ideas used by the company. It did not only teach me about techniques and performances but it also thought me something else about life, â€Å"that however old you are you can be as young as a toddler† and the second lesson and important message of all is that â€Å"You cannot always get what you want†. I hope too, that one day that however old I or anyone else gets we will never lose the young ness within ourselves just like the characters of Road to Heaven.

Chapter # 1 Introduction 1. 1: Basic Introduction Radio Controlled (RC) plane is basically a smaller prototype of an actual aircraft and its dynamics are relatively difficult to understand. For RC Plane there is 3-degree of freedom. Important parameters are: roll, pitch and yaw. To achieve control of these parameters, there are three control surfaces ailerons, elevators and rudder. 1. : Transmitter/Receiver †¢ A Transmitter is an electronic device that gener ates and amplifies a carrier wave, modulates it with a meaningful signal derived from speech or other sources, and radiates the resulting signal from an antenna. The transmitter used for project has 6 channels and is programmable for both airplanes and helicopters. It has a 3-way flap switch, aileron and elevator dual rate switches, rudder mix switch, gear and aux2 switch. A preset memory makes it possible to set up several different models on the same radio. †¢ A  Receiver  converts signals from a radio  antenna  to a usable form.It uses  electronic filters  to separate a wanted  radio frequency  signal from all other signals, the  electronic amplifier  increases the level suitable for further processing, and finally recovers the desired information through  demodulation  and  decoding. Information carried on a radio signal may represent sound, images or data. We are using a 6 channel tiny 4 grams receiver with signal path diversity. 1. 3: Microcontro ller We will be using Arduino AT-Mega 328 Microcontroller and it has a dedicated PWM pin. It has built in ADC therefore no external ADC is required and it is very much faster than Atmel Microcontrollers . 4: Digital Gyroscope How Gyroscopes Work: Gyroscope can balance on almost on any surface with single contact: It can be a finger or even a string. They can resist motion about the spin axis in very odd ways; but the most interesting effect is that gravity-defying part which is called  Precession. We will be using Eclectic Gyroscope in our RC Plane to provide it with stable Flight. We are using Gyro ITG 3200. Chapter # 2 Literature Review 2. 1: History The earliest examples of electronically guided model aircraft were hydrogen-filled model  airships  of the late 19th century.They were flown as a music hall act around theater auditoriums using a basic form of spark-emitted radio signal. In 1920s, the  Royal Aircraft Establishment  of Britain built and tested the Larynx, a  monoplane  with a 100-mile (160  km) range powered by a Lynx engine. It was not until the 1930s that the British came up with the Queen Bee, a modified  de Havilland Tiger Moth, and similar target aircraft. Radio control technology has been in use since 1893, when Nikola Tesla created a boat that was controlled by transmitted radio waves. In 1917, the first radio controlled airplane was successful.During World War II, Germany tried a variety of weapons that were operated by radio control. Radio controlled model airplanes have evolved over the years and seen improvements since that first flight in 1917. Chapter # 3 Modeling & Design 3. 1 Modeling of DC Servo Motrors 3. 2: Design of RC Plane 3. 3: Major Parts Of RC Plane Rudder Flex the rudder back and forth to loosen up the foam hinge. The less force needed to move the rudder the less stress is put on the servo during flight. Alternatively cut them off and use clear packing tape to re-attach them, one slice on each side. [pic ] ElevatorAdjust the travel adjust value to the maximum allowed before the servo begins to bind. [pic] Wings Helps the Plane in gliding and to increase the surface area of the plane. [pic] Aileron For maximum throw, the aileron wing servo has to be swapped around vertically. The servo head should be pointing toward the back instead of the leading wing edge 4. Mechanical Analysis All dimensions of the Plane are From National Advisory Committee for Aeronautics  (NACA) , we selected the NACA series of 0015 as it was cheaper to fabricate. The Analysis of the Aerofoil was performed on Gambit & Fluent as these software are used for fluid analysis.We calculated the Coefficient of Drag & Lift using these software to determine whether the plane will fly or not. The coordinates of the NACA series 0015 was taken from the NACA site. Theoretical Calculations †¢ Length of Aerofoil (chord)= 19 cm †¢ Max Thickness of Aerofoil=2. 85 cm (2. 85/19)*100= 15 We Know that our Aerofoil is Symm etrical, therefore the The NACA Series number of our Foil is 0015 †¢ The NACA 0015 airfoil is symmetrical, the 00 indicating that it has no camber.

Scarlet Letter Critical Review Paper essays

Scarlet Letter Critical Review Paper essays Scarlet Letter Critical Review Paper The Scarlet letter is a very important and impacting story to the time back then on the East Coast, to now in 2002.
