Free Essays on Language And Communication In Elementary Mathematics Teaching Free Essays on Language And Communication In Elementary Mathematics Teaching Introduction Somewhere between Vygotsky and Piaget; somewhere between Newton determining the laws of the universe alone with his apple tree, and Andrew Wiles proving Fermat’s last theorem with the aid of his colleagues around the world; somewhere between learning the 3Rs by rote under a strict schoolmaster beating down the slightest whisper, and the neo-pragmatist’s ‘knowledge is conversation’ ideal mathematics lesson of total discourse; somewhere between these opposite ends of their various spectra lies the true role of language and conversation in the mathematics class. If it is the responsibility of the mathematics teacher to encourage students to talk in the classroom (Steele, 1998) then it is more so the responsibility to ensure that that discussion does not damage students’ mathematical learning (Sfard et al, 1998). Orey (1998) proposes that learning mathematics makes powerful problem solvers who can break down complex problems into understandable elements and create clear effective and even original solutions. Successful mathematics students, according to Schielack (2000), can read critically, identify fallacies, detect bias, assess risk and suggest alternative solutions. Cotton (1999) postulates thus that mathematics provides both access to positions of power and the ability to critically analyse the decisions of those in power. If all children then do have a right to the power of mathematics (Wickett, 2000), then the teacher has a responsibility to give all students access. The mathematics register and lexical ambiguity At the beginning of mathematical learning is the language of mathematics - that set of words the mathematician uses to express mathematical concepts and activities: the mathematical register. A well-defined, universally accepted vocabulary of terms and expressions allows mathematics to be studied the same way the world over. (Booker et al, 1997). Therein lies the problem.

Determining Significant Figures

Determining Significant Figures Every measurement has a degree of uncertainty associated with it. The uncertainty derives from the measuring device and the skill of the person doing the measuring. Lets use volume measurement as an example. Say you are in a chemistry lab and need 7 mL of water. You could take an unmarked coffee cup and add water until you think you have about 7 milliliters. In this case, the majority of the measurement error is associated with the skill of the person doing the measuring. You could use a beaker, marked in 5 mL increments. With the beaker, you could easily obtain a volume between 5 and 10 mL, probably close to 7 mL, give or take 1 mL. If you used a pipette marked with 0.1 mL, you could get a volume between 6.99 and 7.01 mL pretty reliably. It would be untrue to report that you measured 7.000 mL using any of these devices because you didnt measure the volume to the nearest microliter. You would report your measurement using significant figures. These include all of the digits you know for certain plus the last digit, which contains some uncertainty. Significant Figure Rules Non-zero digits are always significant.All zeros between other significant digits are significant.The number of significant figures is determined by starting with the leftmost non-zero digit. The leftmost non-zero digit is sometimes called the most significant digit or the most significant figure. For example, in the number 0.004205, the 4 is the most significant figure. The left-hand 0s are not significant. The zero between the 2 and the 5 is significant.The rightmost digit of a decimal number is the least significant digit or least significant figure. Another way to look at the least significant figure is to consider it to be the rightmost digit when the number is written in scientific notation. Least significant figures are still significant! In the number 0.004205 (which may be written as 4.205 x 10-3), the 5 is the least significant figure. In the number 43.120 (which may be written as 4.3210 x 101), the 0 is the least significant figure.If no decimal point is present, the right most non-zero digit is the least significant figure. In the number 5800, the least significant figure is 8. Uncertainty in Calculations Measured quantities are often used in calculations. The precision of the calculation is limited by the precision of the measurements on which it is based. Addition and SubtractionWhen measured quantities are used in addition or subtraction, the uncertainty is determined by the absolute uncertainty in the least precise measurement (not by the number of significant figures). Sometimes this is considered to be the number of digits after the decimal point.32.01 m5.325 m12 mAdded together, you will get 49.335 m, but the sum should be reported as 49 meters.Multiplication and DivisionWhen experimental quantities are multiplied or divided, the number of significant figures in the result is the same as that in the quantity with the smallest number of significant figures. If, for example, a density calculation is made in which 25.624 grams is divided by 25 mL, the density should be reported as 1.0 g/mL, not as 1.0000 g/mL or 1.000 g/mL. Losing Significant Figures Sometimes significant figures are lost while performing calculations. For example, if you find the mass of a beaker to be 53.110 g, add water to the beaker and find the mass of the beaker plus water to be 53.987 g, the mass of the water is 53.987-53.110 g 0.877 gThe final value only has three significant figures, even though each mass measurement contained 5 significant figures. Rounding and Truncating Numbers There are different methods which may be used to round numbers. The usual method is to round numbers with digits less than 5 down and numbers with digits greater than 5 up (some people round exactly 5 up and some round it down). Example:If you are subtracting 7.799 g - 6.25 g your calculation would yield 1.549 g. This number would be rounded to 1.55 g because the digit 9 is greater than 5. In some instances, numbers are truncated, or cut short, rather than rounded to obtain appropriate significant figures. In the example above, 1.549 g could have been truncated to 1.54 g. Exact Numbers Sometimes numbers used in a calculation are exact rather than approximate. This is true when using defined quantities, including many conversion factors, and when using pure numbers. Pure or defined numbers do not affect the accuracy of a calculation. You may think of them as having an infinite number of significant figures. Pure numbers are easy to spot because they have no units. Defined values or conversion factors, like measured values, may have units. Practice identifying them! Example:You want to calculate the average height of three plants and measure the following heights: 30.1 cm, 25.2 cm, 31.3 cm; with an average height of (30.1 25.2 31.3)/3 86.6/3 28.87 28.9 cm. There are three significant figures in the heights. Even though you are dividing the sum by a single digit, the three significant figures should be retained in the calculation. Accuracy and Precision Accuracy and precision are two separate concepts. The classic illustration distinguishing the two is to consider a target or bullseye. Arrows surrounding a bullseye indicate a high degree of accuracy; arrows very near to each other (possibly nowhere near the bullseye) indicate a high degree of precision. To be accurate, an arrow must be near the target; to be precise successive arrows must be near each other. Consistently hitting the very center of the bullseye indicates both accuracy and precision. Consider a digital scale. If you weigh the same empty beaker repeatedly, the scale will yield values with a high degree of precision (say 135.776 g, 135.775 g, 135.776 g). The actual mass of the beaker may be very different. Scales (and other instruments) need to be calibrated! Instruments typically provide very precise readings, but accuracy requires calibration. Thermometers are notoriously inaccurate, often requiring re-calibration several times over the lifetime of the instrument. Scales also require recalibration, especially if they are moved or mistreated.

Workplace Observation Paper Essay Example | Topics and Well Written Essays - 500 words

Workplace Observation Paper - Essay Example The portal does indicate an attempt to increase employees’ sense of belonging. Wal-Mart previously did not encourage employees to speak out about their working experiences with the retail giant. Walmartfacts.com is now available for employees to post their positive experiences. Where Wal-Mart fails in communications is in addressing the negative issues, the subjects that have brought about all the negative headlines. The retailer is still reluctant to meet with union leaders in communities where it has proposed new store locations. Edd Snyder, executive director, corporate communications, at GM, offers advice that counters avoidance of opposing groups. â€Å"You must find some common ground. The idea is to bridge [differences] and talk and be in constant communication with the other organization. Find common threads† (Frank, 2005). The corporate culture at Wal-Mart is very different from the individual cultures In each store location. Every community has its own set of values or standards. Some are more blue-collar oriented, while others are more white-collar with higher levels of education. The low cost strategy, which many critics believe has ignored environmental and human rights issues does appeal to those who are price conscious. Wal-Mart’s mission statement includes â€Å"our fist responsibility is to provide all consumers (1) the best products and services with guaranteed satisfaction under one roof† (uwstout.edu). Wal-Mart follows through on this promise, by providing securing relationships with low cost suppliers and manufacturers.

Young People in American Society Essay Example | Topics and Well Written Essays - 1000 words

Young People in American Society - Essay Example According to the essay in 1990, students’ (adolescents) violent attitude and violence in schools got dedicated attention from the society. The move was based upon ensuring peaceful atmosphere in schools and colleges and to invest educational resources on productive and learning targets rather than disciplining young students. But evil behind this oppression remained strong and untouched so far and this evil is called ‘adultism’. The adultism is discriminatory ‘ism’ for young members of the society. This particular ‘ism’ consists of closest family members, teachers and elders etc. The after effects of this oppression are very dangerous and endless for example adults may force their dependants to steal, beg, fight, break laws, deal with drugs and adopt prostitution. In addition to illegitimate and immoral activities differential oppression can be inflict with apparently positive and ethical dogmas based upon religious beliefs, cultural trad itions and   regional   limits.From this paper it is clear that governments are allegedly great contributors of differential theory via discriminatory legal system against young people. The lack of protective laws for young people should be considered as oppressive behavior against them.  Our current economic systems are also dominated by certain group which is largely made up of adults. Thus it violates young people’s desires to take part in competition with adults in business and offices.... Political Ageism Governments are allegedly great contributors of differential theory via discriminatory legal system against young people. The lack of protective laws for young people should be considered as oppressive behavior against them. Economic Ageism Our current economic systems are also dominated by certain group which is largely made up of adults. Thus it violates young people's desires to take part in competition with adults in business and offices. Cultural Ageism Even though we are living in more civilized societies, but discrimination on the basis of sex, color, race, religion, ethnicity and age is universally everywhere. Children are among top victims in cultural divisions, they are not even provided with simple choices such as career, education, marriage and employment. Interpersonal Ageism Young people are oppressed interpersonally not only by parents, guardians but also by friends and siblings and sometimes by neighbors and teachers as well. Kind of oppressions by these groups is of discouraging, disrespecting and unrecognized nature. The reaction by the young people in response to oppressions is of severe violence oriented and it can be witnessed everywhere. In United Sates of America this oppression has resulted into extreme youth reactions in form of high rising school crimes, rage, and unlawful activities among students. The introduction of overly restricted rules and regulations is another contributor in juvenile offenses in United Sates, consequently pushing youngsters towards more depression and ultimately societal epidemic. A distinctive element of differential oppression is that the already victimized people (at the time of their youth) are

Current Intellectual Property Rights Essay Example for Free

Current Intellectual Property Rights Essay They say the internet is best source of information when in reality it translates as the best source of information that can be stolen. Current intellectual property rights laws seem to be just pile of papers under a politician’s secretary’s desk. The irony is that it lacks the capability to respond to violations it was intended to contest. If the present conditions continue, new ideas are in danger of being copied and thus hampering their developments. Intellectual property right basically means legal entitlement to intellectual works—such as names, inventions, trade secrets and written and recorded media— thus keeping it safe from being stolen. This is quite problematic because there the notion that no one can be original anymore exists and people don’t seem to care about a work being original at all. Sometimes violations may come in a form of reconstruction of a work, using another person’s work as a model, but if studied closely, they are merely imitations. Violating other’s intellectual property is needless to say a very unethical action. Opportunists save themselves time and the very difficult task of coming up with something original. These violations can be simply called theft in the realm of physical property. Legal problems concerning physical property are much resolved compared to the vague realm of intellectual property. Violations such as theft can be easily charged to the violator of a physical property not legally entitled to them and the properties are properly given legal protection. Protection of intellectual properties is the main objective of the law, but the broadness of the description of the law weakens its credibility. The term â€Å"intellectual property right† is one of the most controversial terms of the present era. It is still disputed and still globally unresolved. It is only half a millennium since the first patents and copyrights were made. Current laws seem to be unqualified to be the solution of eradicating violations to intellectual property rights. The formulation of such laws is obviously inadequate and requires in depth revisions since the problem is still rampant. On the other hand, some critics of the laws says that intellectual property are just present because of they serve a utilitarian purpose. These laws are passed because it would be much convenient to everyone than having them not exist at all. Still, many argue that it is not utilitarian at all because it can only be put into use by cases in which evidences can give support. Unfortunately, ideas can’t be sealed in a plastic bag and presented to the court. And even if these laws are present, a system that can monitor the World Wide Web seems to be far from the capacity of current technology. Since this an international problem, there is no legal system to resolve intellectual property violations if the parties involved are from different countries. Another big question is: who will be enforcing this law? There a group that is capable and has the resources to apprehended violators spread across the globe, so violators are still Not all authors have enough resources to have their work patented. Many authors don’t even bother to have their works copyrighted because they view the process of it as bothersome and expensive. Some even view it as inadequate and has weak credibility. Many are resorting to publishing their work through the internet which is the feeding ground for violators. This poses a threat to the development of new technologies. Companies are now, more than ever dependent on the internet. Violators are not merely copy-and-paste people, some are high-skilled computer hackers that may be employed to steal vital information from the competition. The realistic solution is not to be dependent much on the internet until the intellectual property right law is enforceable and serve its original function. Many is in doubt whether that time may come, but the important thing is that all of us should respect not just the law but the rights of our fellow human beings to create original works and be granted legal rights to those works.

An Envision brought Alive :: essays papers

An Envision brought Alive The video of the glass menagerie met to my exact expectation of the play. While reading the play I could only grasp in my mind the picture of each of the characters, the setting they were in, and the relationships they were engaged in. Therefore I could only envision what I thought their faces would look like or the expressions they were making. But after watching the video I was able to put the puzzle pieces together and finally see what I was missing through the portrayal of characters, the setting, and the relationship between the characters. The portrayal of the characters was done almost exactly to the play. I felt that each of the actors did an exceptional job at this. Amanda’s character came alive in the movie and emphasized her typical role of a nagging and annoying person. Her overall attitude, motions, and facial expressions helped bring alive her character. She expressed tones in her voice, that you wouldn’t be able to hear in reading the play, which helped illuminate her characters determination with dominating over her children and also with winning over Jim. The portrayal of Tom was also done very well, a young man tired of living at home with a mother who will not leave him alone and a sister who he feels bad to leave behind. The actor used good expressions such as the roiling of his eyes to his mother and his angry faces when she pushed him to the edge. In the play I didn’t grasp how frustrated he actually was, but the movie helped me understand with his character. I felt Laura was the b est portrayed character. Her weak and humble attitude, her shy and nervous ways, her small frame, her little girl look were all shown in the video. Her emphasis on her disability was also portrayed well in the movie. In the scene with her and Jim in the living room when he tells her he didn’t even notice she had a problem with her leg, she becomes greatly embarrassed and shy and wants to not talk about that subject. Jim’s character was also portrayed well in the play I found him to not really like Laura or feel bad for her when he tells her he is engaged, but in the movie I found him to be more caring and sympathetic towards Laura and her feelings.

Types of Story Leads

Lead Every news story begins with an introduction called the lead. This may be a single word, a phrase, a clause, a brief sentence, an entire paragraph or a series of paragraphs. The main functions of the lead, aside from introducing the news story, are to tell the story in capsule form and to answer right away the questions the reader would naturally ask. A good lead answers all the important questions of the reader, indicates the attendant circumstances if they are all important, and arouses the readers’ interest to continue reading the story.The lead is the beginning, the most important structural element of a story. Charnley (1966) stated that, â€Å"an effective lead is a brief, sharp statement of the story's essential facts. † The lead is usually the first sentence, or in some cases the first two sentences, and is ideally 20-25 words in length. Leads should: * open with bright, interesting, colorful nouns and verbs be brief (often only 20-30 words) be, for the mos t part, one sentence in length be crisp and to the point effectively summarize the story â€Å"feature the feature† include attribution (the source) if needed for credibility ive the title for any person mentioned not include personal pronouns such as â€Å"we† and â€Å"you† not include reporter opinion Summary lead The typical lead is called a summary lead or straight summary lead, and it, of course, summarizes the story. The journalist must, therefore, write a clear, fairly short sentence that reveals all, telling the end result of the story. Someone should be able to read the lead and be informed about what happened without reading the rest of the story. A summary lead should answer as many of the 5W's and H as possible: who, what, when, where, why and how.The 5 W’s and H provide the news writer with quick and convenient means of organizing the lead of a story. They also provide the framework or structure for organizing the lead of a story. This is on e of the most common forms of hard news story. But, the question is that how do we decide what is most important and what should follow in descending order of importance? Here, we must use our own judgment. Some questions to ask: What will affect the readers the most? What questions does the lead raise that need to be answered immediately? What supporting quotes are strongest?Below are examples of leads which feature the various 5W's & H. The words that make up the â€Å"W† that is featured are in bold face type. | WHO lead Used when the person involved is more prominent than what he does or what happens to him. -Reckless drivers who don't seem to be drunk may well be high on cocaine or marijuana, according to roadside tests that indicate drugs may rival alcohol as a hazard on the highway. -Monica Lewinsky, the former low-level aide at the center of the current White House investigation, is willing to submit to a polygraph examination in exchange for complete immunity from pr osecution, her lawyer said Sunday.WHAT lead Used when the event or what took place is more important than the person involved in the story. -A pack of wild monkeys terrorized a seaside resort town south of Tokyo last week, attacking 30 people and sending eight of them to the hospital with bites. (This also co-features the who. ) -A Soyus spacecraft docked flawlessly with the Mir space station Saturday, bringing a fresh crew of two Russian cosmonauts and a Frenchman to the orbiting outpost — along with a bottle of French wine. WHY lead Used when the reason is more prominent or unique than what happens. With more amateurs cutting wood for use as an alternative to high-priced heating oil, hospitals are coping with an increasing number of injuries due to chain-saw accidents, reported the American College of Surgeons. WHERE lead Used when the place is unique and no prominent person is involved. -Red China will be the site of the next International Film Festival. WHEN lead Rarely u sed as the reader presumes the story to be timely. However, this lead is useful when speaking of deadlines, holidays and important dates. -Today, almost to the hour, the Revolutionary Government was proclaimed by President Corazon Aquino.HOW lead Used when the manner, mode, means, or method of achieving the story is unnatural way. -Louisiana-Pacific Corp. plans to sell seven out-of-state lumber mills and expand production at 17 others in order to boost output by up to 40 percent. (The how in this lead is also the what. ) Novelty leads Novelty leads differ from  summary leads in  that they make no attempt to answer all of the five Ws and the H. As  the  name  implies novelty  leads are novel. They   use   different   writing   approaches   to   present different   news   situations   to   attract   the   reader’s   attention and   arouse   curiosity.Type of Novelty Lead| Example| CONTRAST: The contrast lead compares two opposite extrem es, generally dramatize a story. The comparisons most frequently used are tragedy with comedy, age with youth, the past with the present and the beautiful with the ugly. | In 1914, the United States entered the First World War with a Navy of 4,376 officers, 68,680 men, 54 airplanes, one airship, three balloons and one air station. Today, there are more than 500,000 active duty officers and enlisted personnel, 475 ships and 8,260 aircraft in our Navy. PICTURE: The picture lead draws a vivid word of the person or thing in the story. I t allows the reader to see the person or thing as you saw it. | Thin and unshaven , his clothes drooping from his body like rags on a scarecrow, Frank Brown, USN, today told naval authorities about six-week ordeal in an open rubber boat in the South China Sea. The new principal, although only at his early thirties, is already silver-haired. He seldom talks, but when he does, he talks with sense. | FREAK: The freak lead is the most novel of the novelty le ads.As the name implies, the freak lead employs a play on words, alliteration, poetry or an unusual typographical arrangement to introduce the facts in the story and to attract the reader’s attention. | For sale: One guided missile destroyer. The Navy is thinking about inserting this advertisement. †¦ $ammy $mith, who i$ just $even, wa$ digging in the $and at $amsons beach today and gue$$ what he found? | BACKGROUND: The background lead is similar to a picture lead, except for one important difference. It draws a vivid word picture of the news setting, surroundings or circumstances. High seas, strong winds and heavy overcast provided the setting for a dramatic mission of mercy in the North Atlantic on the first day of the new year. The PNC campus was turned into a miniature carnival ground Sept. 1 during the 85th F-Day celebration of the College. Decorated with buntings and multi-colored lights, the college quadrangle was a grand setting for a barrio fiesta. | PUNCH: The punch lead consists of a blunt, explosive statement designed to surprise or jolt the reader. | The president is dead. Friday the 13th is over, but the casualty list is still growing.Victory Day! Magsaysay High School celebrated March 18 its 5th victory in the city-wide journalism contests. | QUESTION: The question lead features a pertinent query that arouses the readers’ curiosity and makes them want to read the body of the story for answers. Phrase this lead as a rhetorical question. | How does pay in the Navy compare with civilian wagers? Has the space age affected the role of the Navy? | QUOTATION: The quotation lead features a short, eye catching quote or remark, usually set in quotation marks.A quote lead should be used only when it is so important or remarkable that it overshadows the other facts in the story. | â€Å"You really don’t know what freedom is until you have had to escape from Communist captivity, † says Bob Denglar, a former Navy lieutenant a nd an escape from a Viet Cong prison camp. â€Å"The youth in the New Republic have become partners of the government in its struggle for progress and advancement,† thus spoke PNC Dean of Instruction Rebecca D. Alcantara to some 400 student delegates to the 1998 Hi-Y-H-teens Leadership Training Seminar held Dec. 6-39 at the College Auditorium. | DIRECT ADDRESS: The direct address lead is aimed directly at the readers and makes them collaborators with facts in the story. It usually employs the pronouns â€Å"you† and â€Å"your. † | Your pay will increase by ten percent next month. You can receive a college education Navy expense if you qualify under a new program announced this week. | References : http://journalism20. nuvvo. com/lesson/7587-lead-of-a-news-story www. angelfire. com http://photographytraining. tpub. com

Organizational Staffing Plan: Part 2

The purpose of this paper is to provide additional insight into the staffing process to be implemented by the coffee shop. This paper will present several key points in order to procure final loan approval. These points include the formulation of a recruitment plan and strategy, which will be used by the coffee shop initially and throughout the next three years. The targeted communication message and delivery medium will be presented for the purpose of attracting applicants. The selection process to be used will be identified as well as the advantages and disadvantages of this process.The types of initial and substantive assessment methods that can be used to select external candidates and how these assessments align with the staffing strategy will be discussed. And finally, the predictors which will be used to assess the KSAOs will be identified. Recruiting Plan and Implementation Strategy The coffee shop is a smaller business and does not have the staff or budget to run its own rec ruitment functions effectively. The recruitment strategy that will be used to staff the coffee shop initially and throughout the next three years will be the use of an employment website.This open recruitment plan will allow the coffee shop to attract a very diverse set of applicants. The benefit of the employment website is that they will be able to provide the advertising, video advertising, pre-employment screenings, and applicant tracking (Heneman, Judge, & Kammeyer-Mueller, 2012, p. 222). Once the initial recruitment has been accomplished, it will be in the best interest of the coffee shop to change the strategy slightly and move towards a more targeted recruitment plan. The coffee shop will be better equipped to handle placing their own advertisements, utilizing social media, and networking from within the staff.This strategy will benefit the coffee shop because they will be able to seek specific individuals with certain, knowledge, skills, ability, and other characteristics. Creating a Communication Message Once the coffee shop moves into their more targeted recruitment plan, they will need to develop a communication message. The communication message is one of the most important aspects to attracting applicants to the available positions. It will be very important to resist the urge to make the message all inclusive. To increase accuracy, the coffee shop will need to aim for one target audience per message.This will mean that there will be multiple messages, but only one message for each position description. It will also be very important that the targeted message reaches the target audience. Therefore, it is imperative that the message convey the benefits of the position to the proper audience (Massachusetts Service Alliance [MA Service Alliance], 2013). The coffee shop is considering using the following targeted communication message for advertising the coffee server positions. Of course this message is being targeted to the nearby college students. Are you looking for a way to make some extra money? Are you looking for more than just a job? Join us in our warm, friendly coffee shop. This will be different from other jobs. You will enjoy working in our fast paced environment. You’ll have the opportunity to make great connections with our customers while providing them with quality beverages and food products. Come join our team while building relationships that will last a lifetime. We offer flexible schedules, great benefits and an environment that is truly welcoming. Selecting an Effective Communication MediumBecause the coffee shop’s initial strategy is to use an employment website, the communication medium for the recruitment effort would be the internet. Utilizing the internet will enable the shop to recruit from a vast and diverse talent pool of applicants. An employment website is second only to referral as a source of new hires (Heneman, Judge, & Kammeyer-Mueller, 2012, p. 222). Once the initial recruitmen t is complete, the coffee shop will move to a different communication medium. The coffee shop will be able to utilize advertisement options such as classified ads, radio and television ads, and word of mouth.Because word of mouth is one of the most powerful methods of communicating job opportunities, the coffee shop is anticipating that the current employees will be able to ‘sell’ the coffee shop. In order to minimize advertising costs, it will benefit the coffee shop to utilize social media. Facebook, Twitter, and many other social media sites are a great way to reach out to the community. By maintaining pages on these social media sites, the coffee shop not only will be able to advertise for open positions, but they will also be able to advertise the company and drawin new customers. Selection Process Putting the right person into the right position is the goal of an effective selection process. By selecting the right applicant for each of the positions, the coffee sh op will face less absenteeism and employee turnover problems. In addition, the coffee shop will also save time and money (â€Å"Selection Process,† n. d. , Para. 1. ). To begin this process it will be necessary to determine the Knowledge, Skills, Abilities, and Other characteristics (KSAOs). And then determine which KSAOs are necessary to assess the applicants.Once identified, a method to assess the KSAOs will need to be determined. The advantages of selecting the employees this way is that the coffee shop will eliminate unqualified applicants early in the process. However, the disadvantage is that it may significantly lessen the pool of applicants. This may require additional time and cost in advertising again for the positions. Selection Assessment Methods By utilizing an employment website, the coffee shop will be presented with applicants that have been prescreened.However, once the coffee shop is established and discontinues the use of an outside agency, it will need to prescreen them to determine which applicants are likely to be high performers if hired. The initial assessment begins with a review of the resume. This review will be necessary to determine if the applicant has listed any skill or experience that meets the qualification requirements. In the case of the store manager, the coffee shop will be looking for retail experience, supervisory experience, and experience analyzing financial reports.Although, a college degree in business or a closely related field may substitute for a portion of the required experience. In addition, the manager position requires a high school diploma. For the server, the experience should be reflected by customer service and cash handling experiences. Once the applicant pool has been reduced to eligible candidates, a structured interview will be conducted. This substantive assessment will be conducted by the owner of the coffee shop. The structured interview will allow for three to five questions.These same ques tions will be asked of each candidate and will be developed based upon the KSAOs relevant to the position. The questions should reflect the candidate’s behavioral response, either by past behavior or by potential future situations. Benchmark responses and rating scales will be developed in conjunction with the questions to allow for the most desirable evaluation. If it is determined that some of the questions are more important than others, those questions will be weighted. Predictors to Assess KSAOs As seen in the first paper presented, the KSAOs have already been presented.The coffee shop will utilize the necessary KSAOs to further assess the applicant’s knowledge and experience. For the position of store manager, some of the KSAOs that will be necessary are the ability to manage effectively in a fast-paced environment, ability to manage store operations independently, ability to manage multiple situations simultaneously, interpersonal skills, knowledge of customer s ervice techniques, organization and planning skills, team-building skills, ability to plan and prioritize workload, and ability to handle confidential and sensitive information.For the position of coffee server, the KSAOs used in the assessments would be the ability to learn quickly, strong interpersonal skills, the ability to work as part of a team, and the ability to build relationships. In order to predict successful job performance both the resume and the results of the structured interview will be reviewed. The knowledge listed on an applicant’s resume should become highly relevant during the structured interview. The structured interview will allow the candidate to reveal verbal skills, which are necessary to successfully communicate with both fellow workers and customers.The applicants resume will reflect required abilities while the interview will appropriately assess them. Other individual characteristics may be predicted through during the interview. The candidateâ €™s personality, which will not show in a resume, will be revealed at the structured interview.

PHYSICA means "NATURE" in ancient Greek. Ancient Greek philosophers were trying to discover the laws of Nature by pure reasoning, based on logic and general philosophical principles; mostly without experimenting. Modern Science began with Galileo's experiments (in 16th-17th century): not just reasoning, but observation -> hypothesis -> checking the hypothesis with experiments. Aristotle's intuitive thinking lead to the wrong conclusion that "heavier bodies fall faster" Galileo's numerous experiments: "all bodies fall at the same rate, reach ground at the same time". Any difference is explainable by air resistance. Newton: the theory of gravity. Not obvious that falling bodies and planets move under the same rules; experimentally proven. Need for objective description of properties; need for standards. Measurements and Measurement Systems (English, SI, CGS) ...

How Bat Echolocation Works

How Bat Echolocation Works Echolocation is the combined use of morphology (physical features) and sonar (SOund NAvigation and Ranging) that allows  bats  to see using sound. A bat uses its larynx to produce ultrasonic waves that are emitted through its mouth or nose. Some bats also produce clicks using their tongues. The bat hears the echoes that are returned and compares the time between when the signal was sent and returned and the shift in the frequency of the sound to form a map of its surroundings. While no bat is completely blind, the animal can use sound to see in absolute darkness. The sensitive nature of a bats ears enables it to find prey by passive listening, too. Bat ear ridges act as an acoustic Fresnel lens, allowing a bat to hear the movement of ground-dwelling insects and the flutter of insect wings. How Bat Morphology Aids Echolocation Some of a bats physical adaptations are visible. A wrinkled fleshy nose acts as a megaphone to project sound. The complex shape, folds, and wrinkles of a bats outer ear help it receive and funnel incoming sounds. Some key adaptations are internal. The ears contain numerous receptors that allow bats to detect tiny frequency changes. A bats brain maps the signals and even accounts for the Doppler effect flying has on echolocation. Just before a bat emits a sound, the tiny bones of the inner ear separate to reduce the animals hearing sensitivity, so it doesnt deafen itself. Once the larynx muscles contract, the middle ear relaxes and the ears can receive the echo. Types of Echolocation There are two main types of echolocation: Low-duty-cycle echolocation allows bats to estimate their distance from an object based on the difference between the time a sound is emitted and when the echo returns. The call a bat makes for this form of echolocation is among the loudest airborne sounds produced by any animal. The signal intensity ranges from 60 to 140 decibels, which the equivalent to the sound emitted by a smoke detector 10 centimeters away. These calls are ultrasonic and generally outside the range of human hearing. Humans hear within the frequency range of 20 to 20,000 Hz, while microbats emit calls from 14,000 to over 100,000 Hz.High-duty cycle echolocation gives bats information about the motion and three-dimensional location of prey. For this type of echolocation, a bat emits a continuous call while listening to the change in the frequency of the returned echo. Bats avoid deafening themselves by emitting a call outside their frequency range. The echo is lower in frequency, falling within the optimal range f or their ears. Tiny changes in frequency may be detected. For example, the horseshoe bat can detect frequency differences as small as 0.1 Hz. While most bat calls are ultrasonic, some species emit audible echolocation clicks. The spotted bat (Euderma maculatum) makes a sound that resembles two rocks striking each other. The bat listens for the delay of the echo. Bat calls are complicated, generally consisting of a mixture of constant frequency (CF) and frequency modulated (FM) calls. High-frequency calls are used more often because they offer detailed information about the speed, direction, size, and distance of prey. Low-frequency calls travel further and are mainly used to map immobile objects. How Moths Beat Bats Moths are popular prey for bats, so some species have developed methods to beat echolocation. The tiger moth  (Bertholdia trigona)  jams the ultrasonic sounds. Another species advertises its presence by generating its own ultrasonic signals. This allows bats to identify and avoid poisonous or distasteful prey. Other moth species have an organ called a tympanum that reacts to incoming ultrasound by causing the moths flight muscles to twitch. The moth flies erratically, so its harder for a bat to catch. Other Incredible Bat Senses In addition to echolocation, bats use other senses unavailable to humans. Microbats can see in low light levels. Unlike humans, some see ultraviolet light. The saying blind as a bat doesnt apply to megabats at all, as these species see as well as, or better than, humans. Like birds, bats can sense magnetic fields. While birds use this ability to sense their latitude, bats use it to tell north from south. References Corcoran, Aaron J.; Barber, J. R.; Conner, W. E. (2009). Tiger moth jams bat sonar.

NCR Country Club and Different Sampling Design Decisions Essay - 1

NCR Country Club and Different Sampling Design Decisions - Essay Example As a result, the organization had 886 additional survey results. The decision to include spouses was correct since they have a significant impact on the lifestyle and consumer choices of their partners. In addition, the inclusion of nonmembers and employees ensures that the organization gets a global understanding of the issue. In addition, the sampling strategy focused on key aspects of its consumer base. The research involved people who lived in the community, the neighboring areas and outside its area. In addition, it focused on the gender of the participants. The analysis of the collected data showed that the research had succeeded in involving all the key elements of its customers. As a result, the information revealed by the process could be implemented appropriately. Furthermore, it ensures that NCR Country Club has a strong understanding of its market. In addition, it is evident that the researchers considered demographic factors in their sampling strategy. The reference to young consumers shows that the data could be broken down into age groups and other demographic factors. The approach is important because demographic factors have a significant impact on consumer behavior (La, 2005). As a result, the organization will be able to determine how it should handle different types of clients. Consequently, it is clear that all the sampling decisions in this process were handled correctly. In as much as the questionnaire is well designed, it still has some shortcomings. For instance, the questionnaire has not included open-ended questions. All the questions are closed. Although the approach ensures that the participants are focused on the aim of the question, it denies them the opportunity to express themselves. The participants may have important insights that could have helped the organization. The lack of open-ended questions shows that the organization does not care about the feelings of its consumers.
