The volunteer pilot information is currently stored in folder. â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦. Pilot Angels Scheduling System (PASS): Pilot Angels Scheduling System (PASS) is an initiative to evaluate the need for a new system and evaluate alternatives for the existing one. The main objective of this would be to evaluate alternatives and identify a replacement to the current system â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦. Desired Areas of Impact The MOV table below lists the potential areas that this project will impact and summarizes the measurable organizational value of the PASS. At an average the Pilot Angels serves about 100 patients per year. Pilot Angels want to move up the list of top charitable aviation transport services. â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦. This will enable the Huskie staff to schedule flights effectively by reducing the stop-overs from around 5 to 3 for every 1000 flight miles and also reduce the time wait between flights from 2 hours to ? an hour. â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦ Desired Value of the project From the information we gathered and after careful analysis of the problem and opportunity, â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦.. Alternatives Based on research conducted over the Internet OBC team identified the following four alternatives for the PASS. 1. Continue to use the current system. This will referred as Alt 1. 2. Utilize a packaged solution. Review of several scheduling solutions resulted in a clear choice of Flight Operation System (www. flightoperationsystem. com) â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦ a. ASP model: â⬠¦Ã¢â¬ ¦.. can purchase this service for $7,200/year â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦ costs are at a premium of $55 per hour. . This will be referred as Alt 2. b. Individual product model: â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦.. Since this is a proprietary system the programming costs are at a premium of $55 per hour. This will be referred to as Alt 3. 3. Develop a customized flight planning and tracking solution which meets all requirements â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦ The programming costs will be on a regular cost of $45 per hour since the skills required are relatively common. This will be referred to as Alt 4. Analysis of Alternatives The following section analyzes the alternatives Alt 1, Alt 2, Alt 3 and Alt 4 based on Total Cost of Ownership (TCO) and Total Benefit of Ownership (TBO). Total Cost of Ownership The following table analyzes the total cost of ownership for all the alternatives. PASS Total Cost of Ownership Resource Description Alt 1 Alt2 Alt 3 Alt 4 Personnel Time 8 hours of additional work for every [emailprotected] $25. 00 per hour 20,000. 00 5,000. 00 5,000. 00 5,000. 00 Communication Software Programming Training Hardware Support Maintenance Total 27,500. 00 20,700. 00 41,700. 00 31,450. 00 Table 2 PASS TCO Alt 3 has the highest TCO while Alt 2 has the lowest TCO at the time of start up. Since these amounts are only a snapshot figures, it is essential to look at some future projection before the system is finalized. Total Benefit of Ownership (TBO): In order to finalize the products the TBO is an effective tool. Table 5 lists the benefits required for PASS and rates alternatives which are weighted by their relevance to MOV. Benefits Weights Alt1 Weighted Alt1 Alt2 Weighted Alt2 Alt3 Weighted Alt3 Alt4 Weighted Alt4 Functional Track Pilot information 5 2 0. 1 7 0. 35 7 0. 35 9 0. 45 Track Plane information 5 2 0. 1 7 0. 35 7 0. 35 9 0. 45 Track Pilot / Plane association 12. 5 0 Track customer information 7. 5 2 0. 15 Track service information 12. 5 0 0 Match customer request 12. 5 2 0. 25 4 Usability User friendly 7 2 0. 14 7 Availability 8 2 0. 16 6 Phone availability 8 2 0. 16 6 Scalability 7 0 0 6 0. 42 7 Ownership 5 10 0. 5 4 0. 2 10 Security 10 10 1 5 0. 5 10 Weighted Benefits 100 2. 56 5. 90 7. 37 9. 15 It can be found that Alt 4 has the highest benefit relevance to the MOV followed by Alt 3 and Alt 2. The effective alternative can be identified by comparing the TCO and the TBO scores. The following figures compare the TBO with the TCO at the end of 5 years, 3 years and at start up. It can be found that Alt 4 has highest TBO score and has lesser TCO and is an ideal choice for PASS. These analysis indicates that Alt 4 has a high cost during start up in the long run proves cost effective than other alternatives. Required Funding and Support The start up investment for PASS is $ 31,450. This includes the development of the system, implementation and training. The support will be provided at the rate of $750 per yearâ⬠¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦Ã¢â¬ ¦..

Types of Conflict 101 Definition and Must-Know Tips (With Examples!)
Types of Conflict 101 Definition and Musts!) What are the Six Types of Conflict in Literature? (with Examples) Ah, conflict. Canââ¬â¢t live with it. Canââ¬â¢t live without it. Kurt Vonnegut once said that every story is about a character who gets into trouble and then tries to get out of it. Thatââ¬â¢s because who and what we entangle with isnââ¬â¢t just the stuffing for embarrassing Thanksgiving-dinner stories: itââ¬â¢s the types of conflict that drives every narrative forward.It goes without saying that your conflict will affect not only your plot, but also almost every other important element of your story: your characters, theme, tone, and setting. In that sense, figuring out your central conflict is one of the most important things youââ¬â¢ll do as a writer.In this post, we'll study the different types of external conflict and internal conflict - and figure out what they're going to mean for your own story.What is conflict in literature?Simply put, the conflict of a book is a struggle between two opposing forces. It starts when something stands in the way of a characte r and their goals. In other words:CHARACTER + WANT + OBSTACLE = CONFLICTThis might sound overly simple, but almost all of the great stories in the world are born from this formula: a protagonist desperately wants something, but can't get it. Simply take a look at these famous external and internal conflict examples for proof:Pip yearns to be a gentleman but the British upper class frowns on social mobility in Great Expectations.à Michael Corleone wants to stay out of the family business inà The Godfatherà but cannot resist the gravity of filial obligation.Fitzwilliam Darcy discovers that he's in love with Elizabeth Bennett in Pride and Prejudice, but for one tiny obstacle: Miss Bennett despises the sight of him. It's uncertain who would emerge victorious in a New York City versus Zeus matchup.Further external conflict examples: Humanity vs. ghosts in Ghostbusters, Humanity vs. aliens in War of the Worlds.With those external factors out of the way, let's look a final type of conflict.Type 6. Character versus selfIt was writer Maxwell Anderson who said: ââ¬Å"The story must be a conflict, and specifically, a conflict between the forces of good and evil within a single person.â⬠Though that might be an oversimplification, it is true that every interesting story will involve a characterââ¬â¢s inner conflict at some point. Thatââ¬â¢s because, as James N. Frey points out in How To Write A Damn Good Novel, a reader experiences the most empathy for a character when that character is in the middle of some intense inner conflict.Internal conflictà will stem from a debate that occurs within a character. It might originate from any combination of the characterââ¬â¢s expectations, desire , duties, and fears. In Hunger Games, for instance, Katniss Everdeen must reconcile her reluctance to kill another human being with the need to survive in the battle arena. Gripping inner tension is often morally complex or universal, and thatââ¬â¢s what will ultimately resonate with your readers.Further internal conflict examples: Pretty much every book! For more specific examples, though, see: Mrs Dalloway vs. self in Mrs Dalloway, Hamlet vs. self in Hamlet, Humbert Humbert vs. self in Lolita, Holden vs. self in The Catcher In The Rye, Pip vs. self in Great Expectations.The difference between internal conflict versus external conflictWhen itââ¬â¢s done right, the interplay between internal conflict and external conflict raises the quality of the story altogether. A characterââ¬â¢s internal conflict adds complexity to the external conflict while the external conflict drives inner change. Otherwise, your character will simply be one-dimensional.Perhaps the best way to think about this is to look in the nearest mirror. What kind of internal conflict do you go through yourself? Doesn't it influence the struggles that you face externally?To use an example from literature we all probably know, let's briefly visit Clarice Starling in The Silence of the Lambs. There's her internal conflict: she wants advancement in the FBI - but most desperately of all, she wants to silence the screaming of the lambs in her dreams. This internal conflict is then teased out and used to fuel the external conflicts between Clarice and Hannibal, and Clarice and Chilton. Both are intrinsically tied to the other in Clarice's character arc, and should be written as such.How can I practice writing these types of conflict?If youââ¬â¢re struggling to come up with a good central conflict, try going back to the basics and thinking about it through the below two methods.The Character-Based PracticeIt never hurts to remember one of fictionââ¬â¢s #1 guidelines: it always comes down to character in the end. So one thing you can do to brainstorm is to return to your cast of characters. Start by re-evaluating the things that make them tick. Ask yourself:What are their fears and core values? (This is vital if you want to create a strong internal conflict.)What are their (conscious or unconscious) desires?Which one of those desires would get the character upending everything to achieve? Could that form a central conflict thatââ¬â¢d provide the basis for a satisfying story?To brainstorm internal conflict, John Vorhaus suggests putting ââ¬Å"butâ⬠into an equation with opposing forces, such as: I love my younger sister, but Iââ¬â¢m a danger to her because of my ice powers, or I want Daisy Buchanan, but Iââ¬â¢m a poor boy from the Midwest. Try it for your characters!Here's a free character profile template to get you started. And if you need specific character development exercises for inspiration? Check out this post.The Theme-Based PracticeGenerally, the central conflict teases out - or makes clear - the theme of the book. In Romeo and Juliet, for instance, the conflict between the two noble families of the Montagues and the Capulets is the perfect backdrop for the Love versus Hate theme that pervades the play.If youââ¬â¢ve already got a sense of what you want your theme to be, think about ways that the central struggle could best complement it. Will it raise the questions that you want readers to consider? Will the resolution of the external and internal conflict convey the message that you wantà toà deliver? If you remember that conflict is just one part of the whole, youââ¬â¢ll experience a much easier time creating the package deal.Which of the six types of conflict are you writing? How do you approach writing conflict? Share your thoughts in the comments below.

Heres What You Really Sound Like In Job Interviews
Heres What You Really Sound Like In Job Interviews You thought you nailed your last interview. You thought you made a great first impression. You totally answered all the tough interview questions they threw at you, asked them interesting and smart questions. And when they asked you if you had anything to add, you totally had stuff to add. This video by Fastcompany highlights the most common mistakes people make at job interviews. See, thereââ¬â¢s what you say during a job interview, and then thereââ¬â¢s what they hear.Often in interviews, generic answers do not go down well. Your responses to questions are going to be interpreted, and any deviation from what your interviewer wants to hearà might reflect poorly on you during the interview. This doesnââ¬â¢t mean they are inherently impossible to master; they just require a little careful thinking and planning. Remember- when going into an interview, the worst thing you can do is come unprepared!You say: ââ¬Å"Sorry Iââ¬â¢m late, there was so much traffic.â⬠This mi ght be true. You never know when it comes to public transportation. I habitually leave way earlier than I have to and amà still sometimes late because the 4 and 5 trains decide to break down for 30 minutes. But this doesnââ¬â¢t matter, becauseThey hear: ââ¬Å"I just donââ¬â¢t care about your time!â⬠It sucks. But what can you do? Just donââ¬â¢t be late.You say: ââ¬Å"What happened with my last job? They didnââ¬â¢t know how to take advantage of my skills.â⬠à Yes, this is a very tricky question to answer. You donââ¬â¢t want to badmouth your old company- but truth be told, your unhappiness is actually why you are looking for a new job right now. However, when you say something like this,They hear: ââ¬Å"I have no useful skills.â⬠Yeah, this is not good. Here are some great tips to help you prepare for a job interview.You say: ââ¬Å"My biggest flaw is my perfectionism.â⬠When we are asked this type of question, our first instinct is to paint one of our positives as a negative so it wonââ¬â¢t reflect badly on us, but the problem is thatThey hear: â⬠My biggest flaw is that I am a liar.â⬠The best way to handle is question is to first identify anà actual weakness and be honest about it, but also talk about how youà are working toà conquer that weakness. This type of question is actually less about your actual skills, and more about your character.You say: ââ¬Å"Do I have any questions for you? Yes, whatââ¬â¢s your vacation policy like?â⬠à Donââ¬â¢t! Just donââ¬â¢t ask this question, no matter how innocently you askâ⬠¦Ã They hear: ââ¬Å"I canââ¬â¢t wait to not be at my new job!â⬠You only start talking about benefits when youââ¬â¢ve actually been offered the job.You say: ââ¬Å"I am a team player and a people person.â⬠à Although itââ¬â¢s fine to mention that you are a team player and work well with others, always make sure to back up this assertion with examples, or else it just sounds clichà ©.They hear: ââ¬Å"all I have to offer you areà clichà ©s.â⬠Quick noteâ⬠¦If you are watching this at workâ⬠¦make sure to turn down the volume or use your headphones!

Not sure Essay Example | Topics and Well Written Essays - 1000 words
Not sure - Essay Example This entails display of excellent characters thus, promoting human virtues. Confucians have an optimistic view of humankind. They believe in the possibility of the ordinary man to become awe- inspiring and thus, man is teachable, perfectible, and improvable. This is achievable through personal as well as communal endeavors and is possible by self-creation and self-cultivation. Moreover, it focuses on cultivation of virtues such as ren, yi and li (Juergensmeyer, 70). Ren advocates for humaneness and altruism for people in the society, yi advocates for moral disposition to shun evil and righteousness while li advocates for the propriety and norms on human behavior in a society. On proper governance, it advices a person who wants to rule to first rule or govern himself before governing others (Haynes, 14). Therefore, for one to become a good leader, he should understand the principles and values for governing as this would provide him with the knowledge necessary for ruling others. Both Taoists and Confucians promote human virtues for honesty and naturalness for a successful life (Juergensmeyer, 70). They promote such values since they make life more comfortable and facilitate peaceful coexistence. However, Taoists disagree with the notion of governance through the establishment of laws and regulations. It sees the laws and regulations as a means of promoting rebellion and restricting the way man should live on earth (Haynes, 12). Conversely, Confucians accept the issue of governance, but on condition that the ruler first rules himself before ruling others. Taoists and Confucians have positive implications on human life and proper governance in that they facilitate the establishment of virtues and understanding the principles of proper governance.

The road to democracy was neither straight nor smooth. :: essays research papers
The pathway to achieving a government of social equality in Greece was not without difficulties and deviations. Breaking aristocratic power and influence and giving power to the common people was a process full of many obstructions and difficulties. As J.M Roberts put it à ¡Ã ¥democracy emerged out of Athens unexpectedly and at first almost unobservedà ¡Ã ¦ (Roberts, J.M, 2002 p. 196). The changes that took place in their politics were gradual and therefore it was influenced by many rulers, events and mistakes. Although steps were taken backward in the course of democracy, the people of Athens learnt from these mistakes and strived for a better way of ruling their state. The road to democracy was a slow and plodding development. Early signs that a democracy could emerge in Athens came from them adopting egalitarian attitudes and ideas from the other city states, the colonies abroad and the hoplite phalanx. The Athenians embraced values from the city states around them. In Sparta, a citizen was a member of society who was automatically entitled to certain (even if few) rights. This mindset of equality was later adopted by the Athenians. They also took on some Spartanà ¡Vtype equality values concerning warfare. Colonisation also had important social and political repercussions on the Greek homeland. Colonisation softened the Greeks and opened their mind to different cultures, ideas and forms of Government. Some men must have returned to Greece after living in colonies, bringing with them new ideas and impressions on how to run a political government (Roberts J.M, 2002). The hoplite phalanx was also a great influence on the values and principles to whi ch democracy came to be based on. Broader participation was introduced and à ¡Ã ¥relying on eachà ¡Ã ¦, à ¡Ã ¥working togetherà ¡Ã ¦ and à ¡Ã ¥fighting as oneà ¡Ã ¦ were all concepts that were imperative to the hoplites (Roberts J.M, 2002). It was over about three centuries that these changes of growth and development were made. So although the Athenians were moving forward in establishing an innovative form of government called democracy, it was a slow and protracted process. The road to democracy was not easy and straightforward, for many of the citizens were not accepting of the changes being made. Many good leaders such as Solon had started to weaken aristocratic privilege and give rich traders and manufacturers as much power as the nobles. Solon was the bringer of social justice; he allowed all citizens to prosecute wrongdoers in public lawsuits (JH Routledge, 2000).

The Fall of the Mayan Civilization
The Fall of the Mayan Civilization Elizabeth Putman Professor Jennifer Adrienne Humanities 111 January 26, 2012 Mashkan-shapir was a typical Mesopotamian city, located about 20 miles from the Tigris River, and connected to the river by a network of canals. Despite a flourishing civilization, Mashkan-shapir was abandoned within only 20 years of its settlement. What could have caused this rapid demise? For decades, archaeologists have been searching for an explanation of the Maya collapse. Many theories have been put forward, ranging from conflict and invasion to migration, disease and over-farming. According to a study published in an issue of Science (March, 2003), a long period of dry climate, punctuated by three severe droughts, led to the end of the Maya society. Along with factors such as war and changes in the environment, irrigation techniques played an important role in Mashkan-shapir's collapse. Yes, the same process that allowed farming in this region eventually made it impossible to farm leading to their devastation by starvation. Prolonged droughts also contributed to the lack of food and drinking water. The Mayanââ¬â¢s used irrigation for their crop production. Unfortunately, the rivers were higher than the surrounding plain, so water for irrigation flowed into the field by gravity. The fields were lower than the rivers, subsequently; the water sat in the field and was allowed to evaporate naturally. This led to erosion and the buildup of mineral salts. When mineral salts concentrate in the upper levels of the soil, it becomes toxic for plants. By 2300 B. C. , agricultural production in Mesopotamia was impossible. Many fields were abandoned as essentially useless. Mesopotamian cuneiform tablets tell of crop damage due to salts. Cecil, Jessica (2011) Decline of the Maya. http. www. history. com/topic/maya The majority of Mayanââ¬â¢s either migrated due to lack of food and water, or stayed and perished by dehydration and starvation. Only a fraction of the Maya people survived to resist the Spanish conquistadors in the 16th century. Yes, conflict was significant, as was disease, but I adamantly believe that the core problems was a prolonged drought along with inadequate irrigation techniques. Whatever the cause, the Maya did not die out entirely. Some two million are alive today, principally in the northern part of Yucatan and in Guatemala.
