Business and Management Context

Question: Discuss about the Business and Management Context. Answer: The world today is filled with companies, which compete with one another in order to stay ahead of the race of being at the top or at the first of the race. Top companies of the world participate and undertake many strategies that maximize their profit and give them maximum amount of revenue. The performance and the outcome of companies are affected due to various internal as well as external factors. These factors often contribute to the success and sometimes the failure of the companies to achieve maximum profit and revenue. The companies are often affected by these factors which affect the outcome and the performance of that particular company. The essay discusses the organizational structure of Uber as a company. It also discusses the environmental forces that affect the company, the risks that confront the firm, the organization and business practices and organizational functions of diverse firms. Uber is an American transportation network company. It operates in around 570 cities over the world. The CEO of the company is Travis Kalanick. The company specializes in the taxi service that is provided to the consumers. The company has become one of the leading taxi rental services of the world having its presence in over 570 cities. The company has an efficient organizational set up that has contributed to the company being one of the leading taxi or car rental companies of the world. The organizational structure of any company is important as a detailed analysis of the same helps to analyze the layout and the find out the loopholes and the drawbacks that often affect the performance of the company. The organizational structure of the company is important to consider in order to monitor and analyze the efficacy of the operations of the company. The company is a technology startup that helps the consumers or the customers to avail and also share rides to reach a new destination fr om another. The organizational structure of the company is important to analyze the internal organizational breakdown which can help in the analysis of the operations of the company. The organizational structure of Uber is somewhat like this The environmental forces generally affect the performance of a company. Uber is a transportation company that is one of the leading companies of the world. The company is rapidly growing with its operations being spread out to different cities of the world (Feeney, 2015). The rapid expansion of its business operations shows the popularity of the organization. The identification and analysis of the Porters 5 forces for the company helps to analyze the environmental factors of a company. The five forces help to decide and analyse the factors that affect the performance and the outcome of a company. The Porters 5 forces mainly comprises of five components. They are: the threat of new entrants, industry rivals, bargaining power of buyers, bargaining power of suppliers and the threat of substitutes. Threat of new entrants: Uber is a startup that faces a lot of competition from many new market entrants. The company has many already existing as well as new competitors in the market. The main competitors of Uber in a worldwide basis are Ola cabs, Lyft, Curb and Didi Chuxing. The company lacks the protection from new firms that come up with a ride-sharing format. These new firms charge lesser fare for covering the same distance (Gabel, 2016). Ola is a transportation company that is app-based that is based in India. The company has about over 40,000 cars in the country and provides services to about 22 cities in India. In China, Didi Chuxing is a transportation company that is formed by the merger of two largest transportation firms, Kuaidi Dache. It has about 99 per cent of the market share. A sound funding by giants like Apple Inc, Alibaba and Tencet Holdings backs the company. The company is purchasing the rights of Uber, which means that Uber is losing out almost $2 billion. Companies like Ola, Grab, Ly ft and Didi Chuxing are collaborating with each other to beat the competition and trying to overtake the business of Uber (Bashir, Yousaf Verma, 2016). The company, while setting up the business, parted with a lot of capital, while on the other hand, the other startups depended upon a lesser amount of capital to start their business. Bargaining power of suppliers: The company relies greatly on the vehicles of the owners who drive the car. The business model of the company relies on drivers and the partners who own rides. Uber uses an outsourcing strategy for the assets to persons and its labor that meet the terms and conditions for the use of their web application. It is often difficult to find a substitute for particular drivers. The owners of the vehicles have the freedom to choose over Uber and other companies that are the rivals of Uber. Therefore, it can be observed that the suppliers have and enjoy a greater power (Thursby Berbari, 2016). Bargaining power of the buyers: The customers have at their disposal, many options from which they can choose. Customers can choose from a variety of companies like Ola, Lyft or other ride sharing transportation options. The switching to other options also is very cheap compared to Uber. The system of ride sharing makes it cheaper for consumers to avail the app-based transportation facility. Threat of substitutes: For Uber, taxi services are the closest substitutes including the ride-sharing option. The abundance of availability of other options makes it difficult for Uber to undertake the operations smoothly. The public transportation like bus and taxi also act as a threat of substitute for the company. Competitive rivalry: Uber has many competitors in the market that pose a threat for the company. One of the major competitors of Uber is Lyft. Lyft has an almost similar operations and business models. The competition between the two firms is very intense (Rogers, 2015). The competitors compete for the suppliers as well as the market share. Uber is a market leader but the differentiation strategies of other firms restrict the potential of Uber as a company. Uber is confronted by many risks that exist in the market. Few of the risks are: The low profit margin of the drivers makes them unhappy and dissatisfied with the company. This makes them lock to the other competitive rivals of Uber. This can dispirit the new drivers from choosing Uber (Barro, 2014). Due to some legal rules and regulations that are imposed in various countries like Germany, makes it difficult for Uber to operate. The rules and regulations imposed by the government acts as a hindrance to the growth and development of the company in those countries. The risk of bad reputation due to many fraudulent and dishonest activities of the drivers remains one of the biggest risk for Uber. These types of activities damage the reputation of the company and the brand image of the company. With the advent of technology, there are many important innovations, which are making the need for transportation services obsolete. Self-driving cars from Google and the Segway often offer easier and more comfortable alternative to hiring the facility of transportation activities (Gabel, 2016). One of the main risks that Uber faces is the over-evaluation of a particular location which can lead to over investment in that location. This can lead to the company facing and incurring losses and thus losing out greatly of profitability and revenue generation. Uber Technologies Inc. is a company that has its operations spread out to over 570 cities across the globe ("Sign up to drive with Uber", 2017). It is a transportation company that offers rides to the consumers at a pre decided rate for a specific route. The customers can book the ride with the help of apps which can be accessed through a smartphone. The company operates in about 58 countries ("Sign up to drive with Uber", 2017). The drivers of Uber own their own vehicle or car. The company has a heavy investment in the research and development of the mobile app. The company requires the drivers as well as the consumers to possess a smartphone. The company enjoys a higher opportunity for growth and development in the future. The company, in most cities, offer upfront pricing which means that the average amount of fare that the rider has to pay is shown to the rider before taking the price (Henten Windekilde, 2016). The average earning per hour is $19.04 for the drivers of Uber ("Sig n up to drive with Uber", 2017). The practice of surcharge pricing that is prevalent in Uber is one of the main highlights of the company. It capitalizes on the willingness of the customers to pay more which is directly related to a high demand. Uber relies greatly on the operations and logistics managers of the firm, who are responsible for optimizing and growing the supply side of the market (Gloss, McGregor Brown, 2016). They help in highlighting the potential driver and potential partners. The firm has a culture of experimentation that leads to various projects. There are two divisions of Uber, namely, UberEATS and Otto. References: Barro, J. (2014). Under pressure from Uber, taxi medallion prices are plummeting.The New York Times.

The American Opportunity Essay Example For Students

The American Opportunity Essay Nice T-shirt, said the flight attendant. Written on the front was Student Travel Bureau Since 1970, and  on the back it said, High School Program . I was so excited that I did not miss the opportunity to tell her I was coming, and was from Brazil. It was my second flight on the first day in the famous America. I had left from the largest city in my country on the day before on my way to the United States of America; I was coming to become an exchange student, become fluent in another language, do my last year of high school, and live part of a dream, to live like an American. We will write a custom essay on The American Opportunity specifically for you for only $16.38 $13.9/page Order now I have been living in Lemmon, a little town located in South Dakota. Ill be here for ten months, a school year. I had been studying the English language for four years but I just wished to become a foreign exchange student last year (2013) when one of my best friends told me that she would be and she tried to convince me. In the beginning I did not take the idea very seriously, but after some days, I was reunited with my best friends and she was trying to convince me so we could have the same experience together and another one of my friends that had been an exchange student, lived in Canada for six months, told me that I have nothing to lose and also told me that it is an awesome experience that is hard to describe. So I went talk about it with my parents, I was not having a good relationship with them since some months before, but I created courage and asked them if I could. They told me that they would be willing to pay and help me if I demonstrated more interest, did whatever it took to go, and became a better son for the time I had left in Brazil. I didnt waste time, I got the paperwork from the English school that is partners of a Brazilian company who partners with an American company (International Student Exchange). I had a deadline of two and a half months to get done, and everything got done in one and a half months. Getting my profile in the system earlier made it easier and faster to be chosen by a family. I was chosen almost 4 months before the average date to departure. Now I live with an American family, the couple has two sons and a daughter. I made good friends and Im doing pretty well here, despite everything be different than I was accustomed. Culture, food, life style, schedules, timetable, and behavior are different here but Im not surprised because I knew that would be like that. I didnt give it up and I wouldnt give it up for anything. A lot of people here do not know much about my country. Some people think my country is just soccer, The Carnaval in Rio de Janeiro, and beaches because they dont study about other countries as they usually study their country. My country is all of this and so much more, for example being one of the five major grain producers of the world, and the major soybean producer of the world. 60% of Amazon rainforest is in Brazil. The Amazon rainforest, also known as Amazonia, is one of the worlds greatest natural resources, called Lungs of our Planet. About 20% of earths oxygen is produced by the Amazon rainforest. I have been living here for two months and already know Im not the same anymore. I changed my way of thinking, certainly better, more comprehensive and objective, always seeking my future goals, dreaming, and striving to reach them. That is the American dream, to dream, aspire, strive to realize, and be free as an eagle. Before my experience gets done, I already know that all citizens of the whole world need to know more about their own country and try to transform their country to be a better place, be more proud and patriotic of their country. I may think the American people are crazy and weird because their culture and life style are different than mine, but I admire them for being honest, patriotic, proud, and to be nice with foreign people, all of that is facilitating my life here. America is amazing, Im really glad to have the opportunity to live here.

Steps to Effective Lesson Planning for Grades 7â€12

Steps to Effective Lesson Planning for Grades 7–12 Writing lesson plans ensures that you are addressing the requirements of the curriculum, effectively planning teaching time, and using the best strategies to address student needs.  Ã‚  Your school district may already have a template, or you can use a general lesson plan template as you work through creating your lesson plans. Before Writing the Plan Begin with the end in mind. Ask the following questions: What do you want the students to learn from this lesson?What state or national standards are you meeting?What does the curriculum from your state or your district require?What are the needs of your students in meeting the requirements of the curriculum? Once youve determined this, write a quick description and list out your objectives for the assignment. Ensure that you will provide extra support to students who do not have the skills to meet the objective. Keep a vocabulary list that uses academic vocabulary words  that you can access as you write out your lesson plan procedure. Additionally, decide content vocabulary students will need as well. This will help you remember terms that you need to make sure the students understand as they work through the lesson. Create a materials list and add to this as you write your procedure so that you know exactly what you will need including audiovisual equipment, the number of copies youll need, other required materials, and even the page numbers from books you plan to cover. Creating the Lesson Plan Determine if the lesson is new learning or a review. Decide how you will begin the lesson. For example, decide whether to use a simple oral explanation for the lesson or a pre-activity to determine what students know. Decide the method(s) you will use to teach the content of your lesson. For example, does it lend itself to independent reading, lecture, or whole group discussion? Will you target instruction for certain students by grouping? Sometimes it is best to use a combination of these methods, varying teaching techniques: beginning with a few minutes of lecture- such as five minutes- followed by an activity in which students apply what you taught or a short whole-group discussion to ensure that the students understand what you have taught them. Decide  how you will have the students practice the skill/information you just taught them. For example, if you have taught them about the use of a map in a particular country or town, envision how you will have them practice this information to truly gain an understanding of the material. You might have them complete independent practice, use a whole-group simulation, or allow students to work cooperatively on a project. The key is to get students to practice the information you have presented. Once you determine how students will practice the skills that you taught them, decide how you will know that they understood what was taught. This could be a simple show of hands or something more formal as a 3-2-1 exit slip. Sometimes a game activity can be an effective way to review, or if the technology is available, a kahoot! quiz. Review the draft lesson plan to determine any accommodations you need to make for your class including accommodations for English-language learners and special education students. Once you have completed your lesson plan, include  any details such as  homework assignments. Make any copies of handouts needed and gather materials for the lesson. Tips and Hints Always start with the final assessment, showing that students understand the material you have presented. Knowing the assessments will leave you  better able to focus the lesson on what is essential. Additionally: Refer regularly to curriculum documents and pacing guides.Try not to rely solely on your textbook for lessons, but do ensure that you evaluate any other source you might use like other books, other teachers, written resources, and internet web pages.Some school districts require standards to be listed on the lesson plans while others do not. Make sure that you check with your school district. Always overplan: It is much easier to cut things out of a plan or continue it the next day than fill 15 or 20 extra minutes. If possible, connect homework to real life. This will help reinforce what the students should be learning.

How to Get Any Job You Want with these 7 Resume Hacks

How to Get Any Job You Want with these 7 Resume Hacks The robots are real! They’re here, and they’re coming for your†¦ resume. More and more companies are turning to digital screening processes and online tools to get through the many, many applications they get for open positions. It makes a ton of sense that our approach to resumes and job applications should change, now that the formats and gatekeepers are shifting. You can follow these top resume tips for 2016 to help you get ready to compete with other fifty applicants.Imgur user Stephane Grace has hit on a method for revamping your resume to fit this new digital job hunt, and although his techniques may not work for everyone in every industry, his writeup has a number of great common-sense tips.Here are 7 Steps to â€Å"Hack†Ã‚  the Automated Resume Screeners and Get You Those Job InterviewsYour goal is to get past the robot gatekeepers, and get your (digital) self in front of the human reviewers who take it from there. This thinking takes basic search en gine optimization (SEO) principles and applies it in a more personal way.Step 1: Research and collect data.Start by collecting online job descriptions for the kind of job you’re seeking, and copy them into a master document. While you’re collecting, keep an eye out for common themes and keywords.Step 2: Play job description bingo.Do a more comprehensive review for repeating words and phrases as part of the job descriptions. You can do this review with your own eagle eyes, or you can use free online tools that flag words and phrases by frequency. (Grace recommends SEOBook.)Priority resume keywords: words used in the company’s listed job title, used in the description headlines, used more than twice, called out as success criteriaSecondary resume keywords: mention of competitor companies or brand name experience, keyword phrases (phrases surrounding priority keywords), notable industry qualifications (training, associations)Step 3: Find out how your experience fit s in.Look at your existing resume and your professional experience. Can you make those match  with the keywords and themes you uncovered in Step 2? Make sure to wring every bit of potential out of your hard and soft skills.For example, if a job you want calls for a particular kind of coding experience, but you’ve only taken classes in it (as opposed to hands-on work experience), make sure it’s still noted in the initial resume with terms like â€Å"experience with† or â€Å"exposure to.†Step 4: Boost your skills.If your research up to this point has uncovered some gaps that could prevent you from getting the job you want, start filling in those gaps. Sign up for a class. Do extensive research online. Find a way to get that skill from the â€Å"should have† column to the â€Å"got it!† column.Step 5: Write it all out.Grace’s main argument is that most resumes submitted online are seen by automated eyes only in the first round. Thus, he argues, you can throw out all the conventional wisdom about how short your resume should be, for easy reading, since you’re really just trying to appeal to a word-seeking system.As an editor and someone with an attention span handcrafted by television and the internet, I still think you should be as concise as possible- but the old-school resume limitations are certainly up for debate in this digital age.Step 6: Post it online.Send off your rejiggered resume to the digital winds, posting it on job boards or online application systems.Step 7: Follow up with a more conventional resume.Once you start getting bites, respond with more traditional job application elements. For example, if someone from HR reaches out to you to follow up, attach the shorter-and-sweeter version of your resume (the 1-2 page one you typically use), and include your cover letter pitch if necessary.If you try these methods for your next round of job searching, it’s best to confirm some informati on up front: like that you’re not sending your extra-double-comprehensive resume straight to a human’s email inbox, but rather a generic system. The last thing you want is a â€Å"tl;dr† blow-off if your SEO masterpiece is overwhelming and doesn’t pass through an automated system at all. But if you do want to try to bump up your initial approach and try to get those robots to do your (professional) bidding, you could be that much closer to landing the job you want.

Contrast and compare 'karnak cafe' and 'The day the leader was killed' Literature review - 1

Contrast and compare 'karnak cafe' and 'The day the leader was killed' by Naghuib Mahfouz - Literature review Example This is the uniqueness of the writing style of the author. As the story develops, it becomes poignant without losing its ground and reality. Mahfouz has created a sensational and beautiful character in Qurunfula, the proprietress of Cafe. She is just like the oases in desert. The stern author becomes an entirely different man when he portrays her character. He turns a poet in adoring her qualities of head and heart. How she puts up with the vicissitudes of life is brilliantly elucidated by the author. How intelligently she detaches from her glorious past and maintains her essential dignity as a common individual, is a lesson for womenfolk in any part of the world. The protagonist, though entered the Cafe, by chance, he was surprised to see Qurunfula there in her new role. He describes his past relationship with her in a cryptic style. Mahfouz (2008, p.4) writes, â€Å"We had never had any kind of relationship, whether of affection, self-interest, or simply courtesy.† How and to what extent she is able to retain her past beauty of the body and nobility of soul! Here is another masterful description of the Karnak Cafà © with the presence of Qurunfula. Mahfouz (p.5) writes, â€Å"Here you get to sense past and present, in a warm embrace, the sweet past and glorious present. To top it all, there is that enticement that the unknown brings.† The author has intelligently analyzed the contemporary ground realities of the Egyptian government. Though the governments change, nothing much happens to improve the social and economic conditions of the common people. The author touches upon the issues, how psychological imprisonment works in a seemingly free society, how an atmosphere of fear persists and how people are subjugated. No positive improvement is seen to break the age-old societal traditions, the freedom of the individuals is not guaranteed. It is a peculiar type of
