Moment noodles are famous and much of the time devoured by the vast majority today. Be that as it may, most purchasers are dumbfounded with regards to the harms these items incur on their bodies. By exploring the most well known brands of moment noodles here in China, we will have the option to precisely discover the â€Å"most healthy† brand of moment noodles dependent on its oil content. Thusly, we will have the option to forestall the various medical issues that have occured from these items from emerging once more. Besides, the restricted brands of noodles likewise impede us from having a more extensive examination on the theme. Related Literature From the time Momofuku Ando built up the principal moment noodles, they have ruled the noodle business, and its belongings can in any case be seen today. Their fundamental clients are the undergrads and others who are consistently in a hurry, individuals who don't have the opportunity to prepare breakfast, or individuals who are languid to. Moreover, as indicated by english. ndtv. com there have been high measures of plasticizers in moment noodles in China.The procedure of making the noodles is the thing that influences the water permeableness of the noodles. Truth be told by Beijing time progress innovation improvement co. LTD. , moment noodles are made out of an assortment of batters, which are framed to make noodles, cooked, at that point southern style in oil. They are then gotten through air blades, which doesn't in any case, expel all the oil. This is the reason moment noodles contain such high measures of oil, which causes kidney stones, and keeps it from engrossing water.Oil isn't the main unfortunate material in moment noodles. Truth be told by Dr. Edmond Lee, moment noodles likewise contain high measures of starches, sodium, MSG, and immersed fat. This is the reason we test the noodles for its water permeableness, since it is one of the components that will show whether a moment noodle item is hig h regarding oil-content. This is on the grounds that oil and water don't blend when something is canvassed in oil water won't have the option to go through in this way less water absorbency.We plan to test the water receptiveness by soaking the noodles in water and estimating the measure of unabsorbed water left. By doing this we can assist individuals with picking the moment noodles with the least oil content, in this way helping them forestall different afflictions brought about by the moment noodles, and helping them get as much supplements as possible acquire. Besides, the network will be progressively educated regarding the best brand of moment noodles with the help of this examination.

Child Development And Childhood Development - 1564 Words

Child Development 2 to 5 Years By creating a decent understanding of parenting strategies and childhood development, this will help parents understand and comprehend exactly what to expect and how to provide what their child needs during each developmental stage of their life. All parents can benefit, also those who work with children can benefit greatly by increasing their knowledge, awareness and understanding of overall childhood development. The stage of child development I have chosen to discuss is 2 to 5 years old. This developmental stage is often referred to as the â€Å"preschool years† where children learn a great deal. The reason I chose this stage is because I believe it is very broad and quite a bit goes on during this stage in a child’s life. When a child begins to take the first steps on their very own, they are free to explore and roam around their own little world; this opens up a brand new phase of development. During the preschool years, children are able to take huge leaps in lang uage development, discover independent nature, self/emotional regulation and rapid physical and intellectual development. As preschoolers enter and exit the â€Å"terrible twos,† their language skills change radically. Parents, caregivers and other family members play a strong role and influence on a child’s development of language and pre-literacy skills.

Supporting Teaching and Learning Level 3 Diploma free essay sample

At present employed at Cheam Park Farm Junior School in Year 5 as per the job description (see attachment 1) I have a range of duties such as enabling access to learning pupils and to assist the teacher in the management of pupils and the classroom. Supervising and providing particular support for pupils and ensuring their safety and access to learning activities but also challenging children to make them work to the best of their ability. Supervising children at playtime and making sure there playing safely individually and in groups. Setting out activities asked by the teacher and clearing up after the lesson has finished, delivering interventions groups and working one to one for the lower ability that may need more support, also making relevant resources to help the children with their learning. 1. 2 The introduction of the standards for Teaching Assistants to see a clear path for progression which therefore the role of the TA has become more valued and professional. The qualifications available for Teaching Assistants are as followed Level 2 in Supporting Teaching and Learning, Level 3 Certificate Supporting Teaching and Learning, Level 3 Diploma in Supporting Teaching and Learning and becoming a HLTA which a in job status and is up to your work place to do so, to progress even higher foundation degree/QTS are available. As a TA`s role has become professional more emphasis is now placed on CPD so that the TA can evaluate their classroom performance skills to become more qualified. In addition TA`s must also have qualities such as being a good communicator, be a good listener, a concern and understanding for children, being able to build good relationships with children and colleagues, working well in a team, being sensitive and enthusiastic and being able to use their initiative when necessary and willing to undertake a CPD to be able to reflect and progress in the job. Other Expectations needed to be reached in order to be a competent TA are, emotional intelligence, be a good listener, be consistent and have a good sense of humour. Outcome 2 2. 1 Reflection is important as it helps us identify what we think we do and what we actually do such as Donald Shon introduced the concept of reflective practise he claimed that reflection is a continuous process from a personal perspective, by considering critical incidents through life experiences. There are two types of reflection, reflective in action which is during being able to think on our feet and adjust what we are doing this comes from our experience and knowledge, whereas reflective on action is after the event has finished and reflect on what we do and why. It is helpful to have feedback from more than once source to that we can use the critical reflection to become more experienced and do our job to the best we can be. Sometimes we find it hard to judge our own performance, we may not like to compliment or criticise ourselves but unless we use reflective methods, how are we going to teach effectively and better our knowledge. As a teaching assistant we teach: Lifeskills Social skills Manners He identified that there were four different lenses in which reflection could be used to increase our awareness to be critically reflective. The Autobiographical Lens- Based upon our own individual experiences and influences what we view as acceptable behaviour and how we judge others. Our Students Eyes- Based upon how the pupil see us and do we meet their expectations of what a teacher should do. Our Colleagues experiences- This is based on how colleagues observe and judge us. Theoretical literature- This is the use of all Medias: Magazines, Television and reports to underpin reasons for our practice through theory. 2. 2 Reflecting on my practise by identifying personally what I found hard and how I could improve and gain more knowledge and extend. Also by completing a SWOC analysis(see attachment 2) for my own feelings and what I as an individual would like to gain more knowledge on and what current opportunities would be available to me and what may prevent me from turning my weaknesses into strengths. In class I also answered some questions on what I have learnt about myself as a TA and what were my highest/lowest emotional moments in the current week this was a good way of reflecting on my practise as made think on what my strengths and weaknesses are and what I need to progress on (see attachment 3) In my place of work we also every 6-8 months have a performance management meeting with our line manager to discuss what courses we would like to attend and what we would like to progress on(see attachment 4). During the course of Unit 332 we complete a PDP (personal development plans) by using SMART targets to address development/learning we want to improve on ( see attachment 5). Specific- target states exactly what is required Measurable- you have to be able to measure whether the target has been achieved Achievable- the target should be accessible Realistic- you have to have access to the training or resources required Time-bound – must have a time limit (short/mid/longer term) Johari`s (Luft 1970) The Jorahi`s Window is like a grid It goes from the obvious and more conscious areas of your life to the less obvious areas that you may not be aware of, starting in the unconsciously incompetent such as a blind area to then becoming unconsciously competent where you are good but you don’t realise or need to develop to then becoming consciously competent, and I as an individual would like to continue to develop and progress my knowledge. 2. 3 There are four main influences that may affect our working practise; institutional the work place and what the school stands for and how to promote and reinforce the ethos. Professional the things that each individual believes and putting them into practise, which comes from their professional background. National and Regional beliefs which are what individuals and groups believe and stand for because of their background. Personal values are views and opinions which have influenced us by parents, teachers, media, politicians, friends, colleagues and personal life experiences. An important part of personal and professional development is to be aware of differences and how to respond to them, we must be open minded, if you fail to do this is may interfere with the standard of the codes and practises for working in the children’s environment. We must treat others how we wish to be treated ourselves and that their values and beliefs are important and although they may be different to your own, this is what gives us our own individual personalities. Outcome 3 3. 1 My job description and the level 3 standards are based around my performance, knowledge and understanding of Supporting Teaching and Learning. My job description (attachment 1)clearly states to be up to date with Level 2 supporting children which I am qualified in and have recently passed my Level 2 Cert Qualification and continuing my qualification by becoming more experienced with Level 3 Cert , also being up to date and having a record of recent and relevant in service training such inset days which I attend at the start of each term to keep and weekly Teaching assistant meetings with our SENCO to have a regular understanding on different ways of how children learn and if to go any relevant courses. By using new skills in your performance to ensure the children are learning the best way for that individual and what new strategies are being put in place. I would like to improve my knowledge by going on courses that are relevant and keeping up to date with new procedures that are put in place. 3. 2 I have received different types of feedback from working at Cheam Park Farm; School monitoring Evaluation HLTA/TA planning from which I received from my schools SENCO ( see attachment 6 ) My PDP from work ( see attachment 4) Regular Teaching assistant meeting agendas which I attend every Tuesday morning ( see attachment 7 ). Outcome 4 4. 1 TA`s can engage in CPD Every day. By assisting in the classroom we are observing how our colleagues work and we can absorb this information and put into practise to improve our performance. When I am working in the classroom I get plans of what we will be doing and who I’ll be working with so I have time to gather resources to support and assist the children to meet the needs of the individual and can identify areas which I need to work on and ask the teacher if I’m unsure. The schools learning strategies are rapidly  changing and we must be able to uphold these changes and new methods. We can also ask other staff in the school such as other TAs/HLTAs and observe them to gain more knowledge and new methods and ideas we can use. At Cheam Park Farm we are always engaging in training and have weekly meetings with our line manager (SENCO) to be given training and to discuss different methods and ways of working when in the classroom assisting the children a nd teacher, we also have to complete planning at the end of each lesson to say who we supported and what methods we used to teach the individual. It is important to identify priorities when agreeing a plan, as this is all about you and your needs as we all have different abilities and areas of concern, these areas can be improved and developed will be on going, as the school environment is changing and expectations are getting higher so our skills needs to be constantly increasing. The areas of priority for development are stated in my PDP( see attachment 5). 4. 2 As an employee of Cheam Park Farm Junior School I attend regular Performance Management meetings and reviews where I Discuss with my Line manager ( SENCO ) training I would like to go on and ways of meeting this. (see attachment 45) 4. 3 In class we have had many discussions, we recently worked in groups to discuss and compare our job roles using our individual job description, and then we compared them to what we actually do whilst looking at our job description. We also worked in groups to discuss certain areas we would like to develop in and widen our knowledge by completing a SWOC analysis (See attachment2). The evidence gathered from this allowed me to complete my PDP (attachment 5) with targets using SMART for guidelines, we also answered a list of questions relating to a week of working as a TA (see attachment 3). Outcome 5 5. 1 Since attending college, I have learnt a lot on how to evaluate my progress and how to act on findings. By having group discussions and feedback has helped me to deal with situations effectively also by taking into account different beliefs and values. I always take notes in the classroom and from this can put tasks in to action. I have also learnt that feedback is important and which help me to progress and focus on the certain areas I need to improve. In the classroom I have also realised everyone has different ideas and knowledge but we all want the same results and that there are different paths to follow. 5. 2 One of my tasks in school is to take care of a small spelling group. I have a group of 4 children, of which I do one to one spelling test and helping them find ways to improve their spellings at least twice a week. At the start of the week we have one to one sessions using different resources and strategies to meet that child’s individual needs to give them the best support I can for them to remember and get there spellings right in the test, such as using the LOOK COVER RIGHT CHECK method has helped the majority of my group to become more independent when writing alone, we also have regular phonics group to help them practise sounding the word out. I always feed back to the class teacher on how each child done in there test and if certain child need more help then we always figure out the most suitable time to take the child out to help them and support them in their spellings. I feel I have made a good relationships with each child and find fun but suitable ways to remember there spellings for examples songs or little phrases for them to remember the trickier words. The school must be aware of our achievements and qualifications so they know what the next step of training we should be going on and how to progress. Certificates and qualifications should be available as evidence and helps to keep a portfolio of your achievements to show colleagues later on in the future.

ABSTRACT Leaving the waste materials to the environment directly can cause environmental problem. Hence the reuse of waste material has been emphasized. Waste can be used to produce new products or can be used as admixtures so that natural resources are used more efficiently and the environment is protected from waste deposits. Marble stone industry generates both solid waste and stone slurry. Whereas solid waste results from the rejects at the mine sites or at the processing units, stone slurry is a semi liquid substance consisting of particles originating from the sawing and the polishing processes and water used to cool and lubricate the sawing and polishing machines. Stone slurry generated during processing corresponds to around 40% of the final product from stone industry. This is relevant because the stone industry presents an annual output of 68 million tonnes of processed products. These industrial wastes are dumped in the nearby land and the natural fertility of the soil is spoiled. Therefore the scientific and industrial community must commit towards more sustainable practices. There are several reuse and recycling solutions for this industrial by-product, both at an experimental phase and in practical applications. Keeping the above in view, cement is partially refilled with marble powder in concrete. Concrete blocks replaced with 5%, 10%, 15% 20%. Marble powder have been prepared and compared with standard blocks of conventional cement. These blocks are then tested for properties like compressive strength and tensile strength. The results obtained are quite encouraging. Compressive strength is within the average permissible compressive strength as per IS 2185 (Part1) 1979. As per IS 456 2000 the relation between compressive strength and tensile strength of the obtained result is between the permissible limits. It opens the door for further experimentation in the field of roads and high rise buildings.

Presently large amounts of marble dust are generated in natural stone processing plants with an important impact on environment and humans. This project describes the feasibility of using the marble sludge dust in concrete production as partial replacement of cement. In INDIA, the marble and granite stone processing is one of the most thriving industry the effects if varying marble dust contents on the physical and mechanical properties of fresh and hardened concrete have been investigated. Slump and air content of fresh concrete and absorption and compressive strength of hardened concrete were also investigated. Test results show that this industrial bi product is capable of improving hardened concrete performance up to 10%, The compressive strength of concrete was measured for 7 , and 28 days. In order to evaluate the effects of marble dust on mechanical behaviour, many different mortar mixes were tested. Chapter 2; OBJECTIVES SCOPE OF INVESTIGATION; (2. 1)OBJECTIVES In this project our main objective is to study the influence of partial replacement of cement with marble powder , and to compare it with the compressive and tensile strength of ordinary M20 concrete. We are also trying to find the percentage of marble powder replaced in concrete that makes the strength of the concrete maximum. Nowadays marble powder has become a pollutant. So , by partially replacing cement with marble powder, we are proposing a method that can be of great use in reducing pollution to a great extent. (2. 2) SCOPE OF INVESTIGATION This study is confined to the utilisation of marble dust in place of cement for making concrete blocks. Properties like compressive strength and tensile strength are only studied and suitably is arrived by comparing it with specifications given in BUREAU OF INDIAN STANDARDS (B. I. S). Chapter – 3; STUDY We have referred various projects using marble powder conducted by different research institutions they are 1) In co- operation of marble sludge in industrial building Eco blocks or cement bricks formulation Producing eco blocks to be used in houses ‘building from marble sludge through maximum possible substitution of sludge for sand and other components of the mixed materials used in blocks manufacturing was investigated successfully. By, FAKHER J AUKOUR – THE HASHEMITE UNIVERSITY OF JORDAN 2) Feasibility study of manufacturing eco blocks concrete using sludge powder as raw material. The feasibility study of manufacturing eco blocks concrete using sludge powder as raw material. By , FAKHER J AUKOUR – THE HASHEMITE UNIVERSITY OF JORDAN Chapter – 4; TESTING ON PHYSICAL PROPERTIES OF MATERIALS GENERAL; Concrete blocks are being widely used nowadays. The performance of concrete depends on the quality and quantity of the ingredients such as cement, aggregates, sand, and water. Without the study of the properties of ingredients of concrete work in depth and range, the study of concrete is incomplete. Experimental investigations have been carried out to evaluate the physical and mechanical characteristics of all the aggregates to be used in the manufacture of concrete blocks. (4. 1) SETTING TIME OF CEMENT Initial setting time is the time elapsed between the moment that the water is added to cement to the time that the paste start losing plasticity. The final setting time is the time elapsed between the moment water is added to the cement, and the time When the paste has completely lost its plasticity and has attained sufficient fineness to resist certain definite pressure. Setting time is tested in vacate apparatus. Take 400 gm of cement paste with . 85P water by weight of cement. Where P is the standard consistency of cement. Start stop watch at a instant when the water is added to the cement. Fill the vicat mould with cement paste and smooth the surface of paste and lower the needle gently in contact surface test block. Repeat the process until the needle starts to pierce the block for about 5mm measure from bottom. That time between water added to cement and the needle falls to 5mm measure. IS SPECIFICATION For Portland Pozzuolana cement initial setting time should less than 30 minute and final setting time is not greater than 600 minute. INITIAL SETTING TIME = 34 minutes (4. 2) FINENESS TEST The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate of evolution of heat. Fineness of cement offer great surface area and hence faster development of strength. Weigh accurately 100 gm of cement and place it on a IS sieve 90 micron. Break down the air set lump on the sample with fingers. Continuously sieve the sample for 15 minutes . Weigh the residue left on sieve. It is the fineness of cement IS SPECIFICATION Fineness shall not exceed 10% for ordinary cement. FINENESS MODULUS = 6% (4. 3 ) SPECIFIC GRAVITY Specific gravity is defined as the ratio between the weight of the given volume of solid to the weight of equal volume of water. (4. 3a ) SPECIFIC GRAVITY OF CEMENT (LE – CHATLIER FLASK) Specific gravity is defined as the ratio between the weight of the given volume of cement to the weight of equal volume of water. The test is done in LE- CHATLIER FLASK. The flask is filled with kerosene oil to appoint on stem between 0 and 1ml. Put 100 gm of cement in flask and note the rise of kerosene level in the flask. That is the specific gravity of cement. Weight of cement used= 60 gm Initial reading on flask = 0 ml Final reading on flask= 23 ml Specific gravity of cement= weight of cement used Weight of equal volume of water Specific gravity of cement = 2. 608 (4. 3 b) SPECIFIC GRAVITY OF COARSE AGGREGATE;- Specific gravity of coarse aggregate is found out by pyconometer method.

Hence the partial replacement of cement with marble powder is very effective in solid load bearing unit. Chapter 9 CONCLUSIONS: From our experiment it is proved that marble dust is very effective in assuring very good cohesiveness of mortar and concrete. it is concluded that the marble dust can be used as a replacement material for cement ; and 10% replacement of marble dust gives an excellent result in strength aspect and quality aspect and it is better than the conventional concrete. The results showed that the substitution of 10% of the cement content by marble stone dust induced higher compressive strength, higher splitting tensile strength, and improvement of properties related to durability. Test results show that this industrial waste is capable of improving hardened concrete performance up to 10%, enhancing fresh concrete behaviour and can be used in plain concrete.

The effectiveness of communication in 17th c. to the present essays

The effectiveness of communication in 17th c. to the present essays When comparing the effectiveness of communication from the seventeenth century to the present, twenty- first century, a vast amount of differences are easily observed. It was much harder to easily and effectively communicate during that time period, due to a number of hindrances. For example, there is a huge technological gap between now and then. One of the more advanced method of communication, and fastest, was by horseback. With this thinking in mind, it was an inconvenience getting a message to your friend five miles away. It meant several hours to get a short message to someone. During present times, it would take roughly ten seconds to get and message to someone on the other side of the world. Additionally, there are many different ways to quickly relay a message, such as by phone, cell phone, email, instant messaging, and text messaging, to name a few. While a primitive mail service existed, it was rather ineffective and not worth the hassle or cost. The main reason attributin g to the increased effectiveness of modern communication is such greater knowledge in regards to technology. It allows for much quicker messages to be sent by a great number of sources. During the eighteenth century, there was a limited amount of ways to give and receive messages. Additionally, each way was time consuming and out of the way, especially when one lived on a farm several miles from any other civilization. Another strong point which greatly displays an ineffectiveness in communication is the attempts during war-time during that era. If an attack was made in Boston, it would take several days for this news to reach New York, and months to reach the war commanders back in Europe. Presently, if something happens in Iraq, government officials will know of the happenings within minutes, depending upon the pertinacity of the issue. Such differences surely make the ineffectiveness of communication during the 1700's obvious in regards to the effective...

Sprezzatura - Definition and Examples

Sprezzatura s The rehearsed spontaneity, studied carelessness, and well-practiced naturalness that underlies persuasive discourse. (The opposite of sprezzatura is affectazioneaffectation.) The Italian word sprezzatura was coined by Baldassare Castiglione in The Book of the Courtier (1528): [T]o avoid affectation in every way possible . . . and (to pronounce a new word perhaps) to practice in all things a certain Sprezzatura [nonchalance], so as to conceal all art and make whatever is done or said appear to be without effort and almost without any thought about it. Examples and Observations: Float like a butterfly; sting like a bee.(Muhammed Ali)And all you got to do is act naturally.(Morrison and Russell, Act Naturally)It takes a great deal of experience to become natural.(Willa Cather, interview in the Bookman, 1921)A good style should show no sign of effort. What is written should seem a happy accident.(W. Somerset Maugham, The Summing Up, 1938)Writers are not mere copyists of language; they are polishers, embellishers, perfecters. They spend hours getting the timing rightso that what they write sounds completely unrehearsed.(Louis Menand, Bad Comma. The New Yorker. June 28, 2004)In the presidential debates, everything that the candidates say will have been carefully rehearsed including the ad lib remarks. . . . What a candidate has to do is to memorize the answers to a bunch of questions and know how to look sincere. As a TV producer said, If you can fake sincerity, youve got it made.(Molly Ivins, 1991) Thomas Hardy on Calculated Carelessness The whole secret of a living style and the difference between it and a dead style lies in not having too much stylebeing, in fact, a little careless, or rather seeming to be, here and there. It brings wonderful life into the writing...Otherwise your style is like worn halfpenceall the fresh images rounded off by rubbing, and no crispness or movement at all.It is, of course, simply a carrying into prose the knowledge I have acquired in poetrythat inexact rhymes and rhythms now and then are far more pleasing than correct ones.(Thomas Hardy, notebook entry in 1875, quoted by Norman Page in Art and Aesthetics. The Cambridge Companion to Thomas Hardy, ed. by Dale Kramer. Cambridge University Press, 1999) Cicero on Artful Artlessness When Cicero recommends to the orator a kind of studied nonchalance, he does not mean it as a general rule, to be applied to all types of rhetorical performance; the term appears in the context of a discussion of a specific variety of rhetoric, namely the plain style  ... Castiglione appropriates from Cicero the notion of artful artlessness, as well as its seductive effect: that the audience, finding what it beholds ... is incited to suspect, and desire, the presence of something more than what is actually seen.(David M. Posner, The Performance of Nobility in Early Modern European Literature. Cambridge University Press, 1999) The Inherent Ambiguity of Sprezzatura As dissimulation or artfulness, sprezzatura, like irony, is inherently ambiguous and equivocal. This ambiguity necessarily introduces the question of the audience, for to be successful the courtier must conceal his artfulness, but for it to be appreciated as sprezzatura, his concealment must be perceived.(Victoria Kahn, Humanism and the Resistance to Theory. Rhetoric and Hermeneutics in Our Time: A Reader, ed. by Walter Jost and Michael J. Hyde. Yale University Press, 1997) Rehearsed Spontaneity Being prepared is the key to rehearsed spontaneity in public speaking. Before making a remark, pause and look up like you are searching for something to say. The audience will think you are creating the humor on the spot.   (Scott Friedmann, Public Speaking: Laws of Humor) The Appearance of Effortless Mastery Whether they have designed clothes, written poetry, composed operas, built public squares, painted for popes, hewn marble, or sailed the fathomless seas, many Italians of genius have placed a premium on achieving an appearance of effortless mastery, or sprezzatura, that is attained only by costly, concentrated effort and unremitting labor. In the end, says Giorgio Armani, the most difficult thing to do is the simplest thing.   (Peter DEpiro and Mary Desmond Pinkowish, Sprezzatura: 50 Ways Italian Genius Shaped the World. Random House, 2001) The Gimmick of Straight Talk At the same time that his campaign was beholden to television, [Richard] Nixon was to denounce the medium and other media manipulations. Said the Nixon media strategy guide: [T]he sophisticated candidate, while analyzing his own on-the-air technique as carefully as an old pro studies his swing, will state frequently that there is no place for public relations gimmicks or those show business guys in this campaign.​  (Neal Gabler, Life the Movie: How Entertainment Conquered Reality.

Cross-price elasticity Essay Example | Topics and Well Written Essays - 3000 words

Cross-price elasticity - Essay Example Similarly if the two goods are complements, we should see a price rise in one good cause the demand for both goods to fall. -Cross-price elasticity of demand (CPEoD) for car travel with respect to bus fares is very low and is equal to 0.01>0, but 0.010 so there is no relationship between them. It's clear. If the car travel cost grows, the bus fare will grow too. That's why there will not be the greater demand for this kind of transport. c) How would you interpret the cross-time elasticity of demand for car travel with respect to bus in-vehicle travel, why is it positive, and why is the elasticity higher for peak times compared to off-peak times Does it surprise you that the responsiveness of the demand for car travel is greater with respect to bus in-vehicle time than to bus fares Explain your answer. The elasticity is higher for peak times compared to off-peak times, because during the peak hours the busses move slower than during off-peak hours and the consumer is keener to switch to a car when the bus is moving slower than when it is moving faster. d) Are bicycle and bus travel likely to be substitutes or complements What would be the effect on demand for urban bus travel of construction of new bike paths to central city areas What elasticity measures might be relevant when trying to measure the responsiveness of demand for bus travel to changes in these... c) How would you interpret the cross-time elasticity of demand for car travel with respect to bus in-vehicle travel, why is it positive, and why is the elasticity higher for peak times compared to off-peak times Does it surprise you that the responsiveness of the demand for car travel is greater with respect to bus in-vehicle time than to bus fares Explain your answer. -Bus in-vehicle time increase of 1% during peak hours causes car demand to increase by 0.4% and bus in-vehicle time increase of 1% during off-peak hours causes car demand to increase by 0.3%. It is positive, because the consumer is tempted to switch to a car since the bus is slower. The elasticity is higher for peak times compared to off-peak times, because during the peak hours the busses move slower than during off-peak hours and the consumer is keener to switch to a car when the bus is moving slower than when it is moving faster. d) Are bicycle and bus travel likely to be substitutes or complements What would be the effect on demand for urban bus travel of construction of new bike paths to central city areas What elasticity measures might be relevant when trying to measure the responsiveness of demand for bus travel to changes in these conditions for cyclists -Speaking about cross-price elasticity, bus and bicycle are substitutes theoretically. That's because bus fare rise will entail demand for alternative transport vehicles. But can lots of people change bus trip to bicycle one This effect is possible only after construction of new bike paths to central city areas. After changes in these conditions for cyclists, the demand for bus travel can decrease significantly. We have another situation with cross-time elasticity. Bicycle is a slower kind of

Police Ride Assignment Example | Topics and Well Written Essays - 4000 words

Police Ride - Assignment Example Officer Franz explained that he loved his job and that he loved people, and that he planned to stay with the police force for as long as possible. His career choice was to gain about 3-4 more years of experience on patrol. After that, he would take the civil exam and hopefully move up the ladder in rank. Officer Franz then took a break from answering my questions to explain the numerous safety rules for me to follow, which in all honesty I did not mind, as he truly did seem to have my best interest and safety at heart. I had to wear a standard-issue bulletproof vest, which brought home the reality of the ride-along immediately due to the heaviness of the garment. Officer Franz also explained that I would not be allowed to get out of the car at any time during the ride-along, and again stressed safety above everything else. The area he would be patrolling (with me along) was known as Zone 104, which was primarily a college area, with burglary and robberies being somewhat common calls received. He explained that though anything could come up, most often other than those two types of incidents were calls in which adults were possibly taking advantage of college students, college students throwing loud parties and breaking the local noise ordinances, and local juveniles making mischief. Since it was not a high-crime area, he explained that he would be patrolling alone, as was department procedure, though he did emphasize that two officers patrolled together in the high-crime areas. The shift then began with a roll call for all officers, which lasted about 15 minutes. Most of this involved a report from the previous shift, letting the officers know what to be on the lookout for. Areas of interest, including any to watch closely, are passed on from one shift to another for continuity and continuance in investigations. During the ride-along, I had the opportunity to see police procedure in action three times. Two of the incidents that occurred were minor traffic viola tions, yet they gave me an opportunity to ask questions about procedures behind them. The third incident of alleged gang-rape was not minor and in fact caused me to have to remain with Officer Franz an hour longer than my shift was originally scheduled due to its nature, however, upon explanation, I believe you will agree with me that there was no way to avoid this happening. The first incident was a traffic accident involving two vehicles. Officer Franz handled this quite speedily and professionally. He took the car information and licenses of both drivers and ran it through his computer, which turned up nothing in the way of background information that would cause either of them to be placed under arrest. Given this information, Officer Franz then gave both drivers their information back along with a police report number and an incident number and sent both on their way. I found it interesting to learn that there was a keyboard printer in the patrol car. Officer Franz explained it s uses, which the main use is for printing out tickets and citations. He also explained that there was a central computer program used by the police force, Intel, which kept them informed about data available from crimes in the surrounding area. For example, there was a car stolen in Colony and had he pulled over a car with the same make or model.

AO1- What is meant by the term, â€Å"rite of passage†? Choose one Christian denomination. Describe the main rites of passage in that denomination.   Ã‚  Ã‚  Ã‚  Ã‚  I am going to describe the Roman Catholic churches main rites of passage. There are four important rites, they are; baptism, confirmation, marriage and funerals. A rite is a religious ceremony. If the rite marks a certain stage of someone’s life it is called a rite of passage. Christians believe god gives them powers to do his will, this is called god’s grace.   Ã‚  Ã‚  Ã‚  Ã‚  The first rite I will describe is baptism. When a person is baptised it is believed that it is their welcome into the Christian church. Holy water is either put onto the person’s forehead or they are totally covered in water. This is a rite of passage because it is believed to be a very special as god is accepting them into the church. Infant baptisms in the Roman Catholic church take place during mass so the whole congregation of the church can welcome the child into the Christian faith. The priest takes the service. Three promises must be made but as the child is too young to say them parents or godparents say them on the child’s behalf. The promises are:  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  To turn to Christ  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  To repent sin  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  To renounce evil They also agree to raise the child in a Christian house and faith and say that they believe in the Trinity. The sign of a cross is made on the child’s forehead by the priest while he says; â€Å"I sign you with the cross, the sign of Christ. Do not be ashamed to confess the faith of Christ crucified.† As the priest says the child’s name and; â€Å"I baptise you in the name of the Father, and of the Son and of the Holy Spirit†, he pours water onto the child’s forehead. A lighted candle is usually given to the parents as a sign and reminder that the child is now in the light of god, and not the darkness of sin. After this ceremony the child is part of the Christian family. The child is anointed with oil called chrism, it is to show the child has important work to do in god’s service. Also a white garment is worn to show the light of Christ. The water is a sign of purifying the child.   Ã‚  Ã‚  Ã‚  Ã‚   The second of the rites is confirmation. It is when someone confirms their belief in god and Christ and when someone who has been baptised is old enough to make the promises made for them at their baptism themselves.

Minicase San Pico

San Pico is a rapidly growing Latin American developing country. The country is blessed with miles of scenic beaches that have attracted tourists by the thousands in recent years to new resort hotels financed by joint ventures of San Pico businessmen and moneymen from the Middle East, Japan, and the United States. Additionally, San Pico has good natural harbors that are conducive for receiving imported merchandise from abroad and exporting merchandise produced in San Pico and other surrounding countries that lack access to the sea.Because of these advantages, many new businesses are being started in San Pico. Presently, stock is traded in a cramped building in La Cobijio, the nation's capital. Admittedly, the San Pico Stock Exchange system is rather archaic. Twice a day an official of the exchange will call out the name of each of the 43 companies whose stock trades on the exchange. Brokers wanting to buy or sell shares for their clients then attempt to make a trade with one another. This crowd trading system has worked well for over one hundred years, but the government desires to replace it with a new modern system that will allow greater and more frequent opportunities for trading in each company, and will allow for trading the shares of the many new start-up companies that are expected to trade in the secondary market. Additionally, the government administration is rapidly privatizing many state-owned businesses in an attempt to foster their efficiency, obtain foreign exchange from the sale, and convert the country to a more capitalist economy.The government believes that it would conduct this privatization faster and perhaps at more attractive prices if it had a modern stock exchange facility where the shares of the newly privatized companies will eventually trade. You are an expert in the operation of secondary stock markets and have been retained as a consultant to the San Pico Stock Exchange to offer your expertise in modernizing the stock market. What w ould you advise? Explain. Most new and renovated stock exchanges are being established these days as either a partially or fully automated trading system.A fully automated system is especially beneficial for a small to medium size country in which there is only moderate trading in most issues. Such a system that deserves special note is the continuous National Integrated Market system of New Zealand. This system is fully computerized and does not require a physical structure. Essentially all buyers and sellers of a stock enter through their broker into the computer system the number of shares they desire to buy or sell and their required transaction price. The system is updated constantly as new purchase or sale orders are entered into system.The computer constantly searches for a match between buyer and seller, and when one is found a transaction takes place. This type of system would likely serve San Pico’s needs very well. There is existing technology to implement, the bug s have been worked out in other countries, and it would satisfy all the demands of the demands of the San Pico government and easily accommodate growth in market activity MINI CASE: SARA LEE CORP. ’S EUROBONDS The International Finance in Practice boxed reading in the chapter discussed a three-year $100 million Eurobond issue by Sara Lee Corporation.The article also mentions other bond issues recently placed by various foreign divisions of Sara Lee. What thoughts do you have about Sara Lee’s debt financing strategy? Suggested Solution to Sara Lee Corp. ’s Eurobonds Sara Lee is the ideal candidate to issue Eurobonds. The company has worldwide name recognition, and it has an excellent credit rating that allows it to place new bond issues easily. By issuing dollar denominated Eurobonds to Swiss investors, Sara Lee can bring new issues to market much more quickly than if it sold domestic dollar denominated bonds.Moreover, the Eurodollar bonds likely sell at a lower yield than comparable domestic bonds. Additionally, it appears as if Sara Lee is raising funds in a variety of foreign currencies. Sara Lee most likely has large cash inflows in these same currencies that can be used to meet the debt service obligations on these bond issues. Thus Sara Lee is finding a use for some of its foreign currency receipts and does not have to be concerned with the exchange rate uncertainty of these part of its foreign cash inflows.

Creating The Epidemic Of Blue Green Algae Essay - 1682 Words

When I was a little girl, I spent my summers rafting down and swimming in the rivers of Northern California, minutes from my house. My family would spend hours at the river weekly, having fun and relaxing by the water, but we never truly thought about what was actually in the water. Over the course of a few years, the water started becoming greener, making it so that we could not see the bottom. This cause was from the algae growth in the water. Our county started having health issues from humans and dogs alike, and every case of these issues came from swimming in the rivers. That summer, Humboldt County put a health warning out to the community, asking to stay away from the water. Of course, people would not listen, creating the epidemic of blue-green algae. Algae are the most noncomplex members of the plant kingdom, and the blue-green algae are the most plain of the algae. Blue-green algae have a substantial and increasing economic importance, they have both helpful and life threat ening effects on living beings. Although they are named after algae, they are not true algae. Blue-green algae do not have a nucleus, or chloroplasts. Actually, blue-green algae are more related to bacteria, which have closer characteristics. The activity of nitrogen fixation and the occurrence of gas vesicles are extremely important to the triumph of blue-green algae. Blue-green algae are located in various locations on land and in water, generally in environments where vegetation does notShow MoreRelatedWhy We Need Light And Water1528 Words   |  7 Pagesforce to drink and bath in water that contains a green blue algae coming from Lake Erie that has harmful bacteria called mircocystin that can cause liver damage.
