The Natural, Because My Passion Is Sports - 1291 Words

I chose the book, The Natural, because my passion is sports. I also heard that The Natural was a blockbuster in the cinemas so I decided this had to be my choice. This book did not completely match my expectations. Before I started reading I expected that The Natural would tell the story of a baseball legend’s career and achievements. The story was almost the exact opposite. Roy Hobbs, a young, talented, and ambitious baseball player goes to Chicago to try out for the Cubs. He meets a girl, Harriet, on the train to Chicago whom he immediately falls in love with. Things quickly go wrong as she shoots him when he visits her hotel room in Chicago. This not only seriously injures him, but also keeps him from playing professional baseball for 15 years, putting him past his athletic prime. After Roy enters professional baseball in his thirties, he has a few short years in the league and eventually cracks up and beats up his coach and manager. He would end up jobless and never be able to play baseball again. Nothing goes right for Roy and the baseball gods looks to be against him. The Natural isn’t a story of an athlete’s glorious career as I expected, but a talented player’s career and life going to waste. The story also shows the dark side of sports such as cheating and match fixing. I am undecided about recommending this book. This story’s plot is depressing but reflects the sad reality of many sports stars past their prime.

Journal Of Hospitality Marketing Management â€Myassignmenthelp.Com

Question: Discuss About The Journal Of Hospitality Marketing Management? Answer: Introduction: The report gives an overview of the integrated digital Strategy of Hyatt Hotel through background information and the marketing objectives. The report also analyses the companys opportunity from digital marketing through a situation analysis, Google analytics customization, target audience and SWOT analysis. The report also gives a description of the strategies adopted by Hyatt Hotel in achieving those objectives. There is also a review on digital market channel effectiveness and the action plan implemented by the company. The report also discusses about the converting leads followed by Hyatt Hotels and their focus on engaging customers through various digital means. Background Information of Tourism or Hospitality Company Jay Pritzker purchased Hyatt House Motel located near Los Angeles International Airport in 1957 and renamed it Hyatt. Over the decade, Jay Pritzker and his brother, Donald Pritzker worked in unison with other members of the family to grow the company into a hotel ownership and North American management company. The Hyatt international formed in the year 1968 as a separate public company. However, Hyatt International Corporation and Hyatt Corporation taken over by the Pritzker family as separate business entities in the year 1979 and 1982 respectively. However, the Hyatt International Corporation and Hyatt Corporation consolidated under a single entity in December 31, 2004 and known as Hyatt Hotel Corporation. The Hyatt Hotels Corporation operates in several chains (Cannon Summers, 2014). The Hyatt Regency brand has been the oldest brand in the company with the introduction of Park Hyatt and Grand Hyatt in the year 1980. Some Hyatt brands are resort properties and facilitated with re creational and spa facilities. Hyatt Corporation also has a brand known as Hyatt Place specifically meant for business travelers. The company has five portfolio hotels in Australia known as Park Hyatt Sydney, Park Hyatt Melbourne, Grand Hyatt Melbourne, Park Hyatt Canberra, and Hyatt Regency Perth. Analyze the company Marketing Objectives The marketing objectives of Hyatt is designed for securing and building a brand value and awareness while maintaining the specific needs for business necessary for its operations. The company believes in differentiating and building a brand position of itself and its sub brands in order to not only increase the companys demand and brand preference but also enhance the other business related imperatives (Green Lomanno, 2012). The company along with each of its brands focuses and targets on a specific customer segment and thereby supports the need of the hotels through application and analysis of analytics and data. Thus, the company adopts a marketing objective which is SMART, an acronym essential for analyzing the marketing objectives of a company and is elaborated as follows: Specific: The Company makes sure that the goals are defined in a clear manner Measurable: The Company adopts goals that are measurable and can be defined with the help of required metrics Achievable: Hyatt Hotel focuses on objectives that are attainable Relevant: The Company also set goals keeping in mind the overall goals of the business Time Sensitive: The Company also set a goal that is attainable in attainable within a defined time period. Analyse the Company Opportunity from Digital Marketing The electronic distribution channels have been a vital contributor in Hyatts total number of reservations. The guests might have valuable interactions through the companys website that is Hyatt.com and these messages considered important in determining the marketing and sales effort. The company continuously tries to optimize the brand experience, effectiveness in marketing and efficiency in booking so that the online purchase process facilitated in driving maximum revenue. The company also has dedicated teams that focus mainly on design, architecture, functionality, content of the site, driving enough traffic for site through integrated marketing communication that includes social media, viral marketing, email programs and search engine optimization and marketing (Hsieh, 2012). The company employs sophisticated analytics through its business intelligence unit for increasing the efficiencies in digital marketing and enhancing e-commerce performance. Google Analytics customization The company used the Google Analytics customization by establishing a goal with a set of performance indicators, tracking those goals and through creation of a dashboard. While establishing the goal the Hyatt Hotel considered the traffic medium and source, the bounce rate, the rate conversion, special offer clicks and requests for proposal submissions and clicks to call. After deciding on the site metrics, the company implemented goal tracking and goal prioritization. However, the traffic source medium and bounce tracked it automatically so the company created clicks to call and check rate for further tracking the goal. Further, the company also creates a dashboard through the user-friendly interface and straightforward implementation of Google analytics. Target Audience Personas The Hyatt Hotel has a varied range of target audience that ranges from business travelers to families out on an international and domestic leisure holiday, teenagers and elderly. Therefore, the company also provides varied offerings catering to the need of every client. This may range from the size of the room, food, meeting, rejuvenation and spa facilities. The company believes in creating a memorable experience through its marketing (Tsai, Suh, Fong, 2012). The company tries to embrace the local culture and maintain a community friendly experience. Digital channel specific SWOT analysis The digital channel specific SWOT analysis of Hyatt Hotels is as follows (Chaffey Bosomworth, 2012): Strengths There is a universal agreement regarding the site of the company being perfect and does not create any hindrance and hence requires no sorting The company also has an existing web team that takes care of any updates from time to time The company uses upgraded technology from time to time. Weakness There is always a conflict between various teams for undertaking the role of the website. The web team of the company is busy in undertaking minor updates and does not think in a strategic manner. There are also some limitations on the kind of content published due to the fear of legal risks or the competition. Opportunities The company also has made its presence felt in the social media where competition has little chance of affecting. Through the web, the company gets a unique opportunity of gathering information on leads and target audience. Threats Sometimes analytics shows a very slow decline in the web traffic. The competitors of Hyatt Hotels also have their site relaunched and they might have offering better that what Hyatt has. SMART Objectives and track KPIs using a digital marketing performance The SMART objectives adopted by Hyatt Hotel are specific, measurable, relevant, actionable and time bound that contributes in drawing more visitors to their site thereby leading online revenue generation (Chaffey Patron, 2012). The company tracks seven key performance indicators using the digital marketing performance which are mentioned as follows: Tracks website engagement including number unique site visitors, return visits, time spent on website and opt in registrations. Tries to understand whether web traffic is direct, referral or organic. Here the bounce rates, total conversion and success indicators are also considered. By measuring online campaign performance through cost per click, cost through rate and acquisition Measuring the engagement levels of campaigns undertaken in social media platforms like Face book and Twitter The company also tracks the conversion rate of the landing page Digital Channel Growth Opportunity Analysis Hyatt Hotel has made quite a presence did not have to struggle for making an online presence. With a good mobile presence, everything was quite easy to find for the company. However, the company needs to redesign the website in order to match it with modern design by RoomKey (Miniankova, 2015). There is also need for richer content on the hotel website that would allow more of the hotel atmosphere and brand ethos to mingle up with the booking and browsing process.; Core Digital Governance or Management plan Thus, in order to understand the quality of customers experience on the digital channels the management of the Hyatt Hotel decided to track some additional key performance indicators. These included: Look to Book Ratio (LTB): This indicates a comparison between the numbers of times a hotel property viewed compared to the number of times the customer makes a booking Anticipating the Number of Cross Sells: Indicates the number of times a service sold with a booking in return. Keeping Track of the bounce rates and time spent by the customers. Digital Marketing Strategy How do we get there? The strategy for being digital is solely dependent on technology whether it in the front end of the content management system for the hotel website or booking engines that are at play at the backend. Thus, choice of the right kind of technology can make or break a good customer experience (SW Chan, 2013). Therefore, the hotel enabled their preferred guests to use their phones to not only check in but also unlock doors and get the room number. Customer Segmentation and Targeting Customer segmentation done based on demographic, geographic, psychographic, geo-demographic and behavioral characteristics. However, selecting one of the mentioned market segments in the need to provide better services refers to targeting. Targeting allows the Hyatt Hotel to focus on the efforts that will help in satisfying customer needs. Thus, to cater to the demographic segment the company mainly focuses on the occupation, income and socio economic status since the hotel provides premium service and satisfying the segment would mean more profit (Bowie et al., 2016). The company focuses on the geographic segment by making sure that being a global brand they are located in every part of the country. The company also takes into account the psychographic segment and focuses on businesses people and people with high disposable income as their services matches completely with their lifestyles and personalities. The hotels also divide their marketing based on user status, customer loyalt y, purchase occasion so that these customers facilitated with special services. Online Value Proposition and Experience Online Value Proposition (OVP) defined as the reason for which the customer is willing to avail the service provided by the company. Hyatt Hotel makes sure that it provides the best of facilities to the customers so that they always come back. Customer Experience (CX) refers to the interaction between an online store and the customers throughout lifecycle of relationship. Therefore, Hyatt Hotel understands the value of customer experience and considers it important to make any necessary changes that is required. Digital Media Channel Effectiveness Review Hyatt hotel believe in search marketing that is a process of gaining visibility and traffic fromsearchengines both through unpaid and paid efforts. The kind of marketing encompasses search engine optimization (SEO) that is a free listing or done through unpaid means while search engine marketing (SEM) refers to buying traffic through paid means. Owned and Earned Media Owned media refers to the content that the company is in full control of. Therefore, here the company can decide on the content of the website, blog and social media accounts. In this case, Hyatt Hotel being a brand name has its own website where a team works in unison in deciding its content (Stephen Galak, 2012). Earned media defined by themedia exposure earned by the word-of-mouth.The company also believes in the power of earned media therefore, it tries to deliver services that would enhance customer experience. Paid media Paid media is a method of promoting the content and hence determine the driving exposure. Hyatt Hotel uses paid techniques for promotion in various platforms of social media including twitter, LinkedIn, Face book and Pin interest to enhance its exposure. Online Customer Acquisition, Campaign plans and budgets Hyatt Hotel adopts promotional activities of its services in a manner that is good enough in persuading new customers in availing its services. Hyatt Hotel plans to undertake a Customer Relationship Marketing Campaign through various platforms of social media and television and print advertisements within an estimated budget of $ 500 million in a matter of five years. Customer Journey Analysis The customer journey analysis accomplished by following the below mentioned steps: By defining the behavioral stages that implies that depending on the type of business, the stages of navigation the site by the customers might be different. By aligning the customer goals with the stages will help the company understand what the customers want as they move through each of the phase. By plotting out the touch points the company will be able to understand the instances where the customers gets engaged with the companys site By determining that the customers goals gets fulfilled which will allow the company to understand how easily the customers are able to achieve what they need Accepting recommendations for change and making necessary changes in the website. Website visitor and customer lead capture and profiling Customer lead capture is the prime goal for many business websites. The procedure thereby helps in capturing data that allows a company to send relevant follow up messages that conversion to sale (Hsu, Chang, Chen, 2012). Thus, the improvement of the lead capture process helps the company to increase the quality and number of leads. Customer lead capture and profiling thus involves email marketing, web personalization and retargeting or remarketing. Optimize content Content optimizationrefers to process where aesthetics and performance of the site pages improved for providing unique value to the customers through search engine optimization (SEO), user experience, conversion optimization and content editing. Hyatt Hotel also optimizes its content to gain a better exposure. Optimize Landing or Entry Pages Landing pages are the primary component of online marketing campaigns. This page specially designed for the generation of sales and capturing leads. They are often the main destination of online a marketing campaign that are paid and that involves lot of money and resources for traffic drive (Ash, Ginty Page, 2012). Through increase in the landing page optimization or the entry pages the company not only can increase its reservation but also generate revenue. Content - Campaign planning Contentmarketing is type of marketing technique for distributing and creating relevant, consistent and valuable for acquiring and attracting a defined audience with the sole objective of driving customer action that is profitable to the company. The key word here is valuable. Converting Leads Lead nurturingis the procedure adopted by Hyatt Hotel in relationship development with the buyers at each stage of the sales funnel and through each step of the buyers journey. This focuses on the communication and marketing efforts by hearing the needs of the customers and satisfying them with the required information. Web Personalization Through the website personalization, the company tried to adopt a process of creation of customized experiences for the visitors of their website. Website personalization rather than providing, broad and single experience allows presenting unique experiences to the visitors according to their desired and needs. Multichannel selling Through the adoption of Multi-channelretailing which is an ecommercestrategy for selling, Hyatt Hotel tries to targets customers on channels that are beyond the company's website.The company therefore uses various social media platforms and other mediums approach directly to the customers. Conversion Rate Optimization (CRO) The company takes to conversion rate optimization(CRO) for increasing the percentage of visitors converted to potential customers through a desired action. This along with increasing the profitability of the company can also increase its customer base. Customer Digital Experience Hyatt Hotel now brings to its customers a complete digital experience through the companys website and in various social media platforms where it focuses on spreading messages and thereby connecting to their target customers.

What is Resistance Essay Example

What is Resistance Essay Technically, resistance is defined as the ability of a substance to prevent or resist the flow of electrical current.Electricity is conducted through a conductor, in this case nichrome wire, by means of free electrons. The number of free electrons depends on the material and freer electrons results in a better conductor. For example, a piece of metal such as gold would have more free electrons as the atoms do not hold on to their electrons very well in comparison to another conductor such as plastic which has less free electrons therefore, making it a worse conductor of electricity due to the higher level of resistance. The free electrons are given energy and as a result move and collide with neighboring free electrons. This happens across the length of the wire and thus electricity is conducted.The smaller the cross-sectional area of the nichrome wire is e.g. 20swg, the fewer channels of electrons in the wire for current to flow and as a result of this the resistance will be high bu t having a lower area of wire leaves it more susceptible to a heating effect. However, when the cross -sectional area increases to a value of 36swg for example the resistance will decrease as there are more channels of electrons in the wire (This can be seen in the following diagrams; figure 1 and figure 2).Factors Which Affect the Resistance of the Wire?There are various factors which affect resistance of a wire, three of them being the material of the wire e.g. Nichrome or Gold, the cross-sectional area of the wire, the length of the wire and the temperature of the wire.1Below, you can see the effects these factors have upon the relationship between the resistance of a wire and its length:- The length of the wire: if a wire is longer, the moving electrons have further to go, so there is a higher chance of an electron colliding with an atom. Thus, increasing the resistance in the wire.- The cross-sectional area of the wire: the moving electrons in a current are spread out over a gr eater area. There results in a lower chance of an electron colliding with an atom, so more current can flow. Increasing the cross-sectional area of a wire decreases its resistance, this can be seen by figures 1 and 2.- The temperature of the wire: if the wires temperature increases, its atoms vibrate more, each one moving around a fixed centre. There is more chance of electrons colliding with the vibrating atoms, so less current can flow. An increase in temperature increases the resistance of a wire.Ohms LawResistance is measured in ohms. One ohm is represented with the symbol: ?The greater the number of ohms, the greater the resistance present in a wire.The image on the right shows the relationship between voltage, current and resistance. It can also be understood through the following equation; voltage = current * resistanceV = I * ?Relationship between current and voltage when a resistor follows Ohms LawThe current flowing through a resistor at a constant temperature is directly proportional to the voltage across the resistor. Following those guide lines we can come to believe that if you double the voltage, the current also doubles. This is called Ohms Law. Figure 5 (left) shows what happens to the current and voltage when a resistor follows Ohms Law.Relationship between current and voltage when a filament lamp is present in a circuitA filament lamp is a typically bulb found in many circuits. This contains a filament (typically tungsten) which heats up when an electric current flows through it and creates light. This can be seen by figure 7.The filament lamp doesnt follow Ohms law. The resistance of the lamp increases whilst the temperature of it increases and, due to this the current flowing through the filament is not directly proportionate to the voltage across it. Figure 6 shows the graph which conveys the relationship between the current and voltage for a filament lamp.VariablesDuring this experiment, our independent variable (which will be changed) i s the length of nichrome wire.In order to collect our results, we will measure the voltage (dependant variable) passed through a current of 0.5A whilst varying the length at which the electricity is transmitted through the wire. From this we will compare the relationship between the length of the wire and its resistance.In addition to this, several variables must be controlled during the experiment. Essentially, this focuses on ensuring that the flow of energy throughout the current remains the same in each test, ensuring that the same current is emitted for every test. The following table (table 1) explains this.Control VariableWhy must it be controlled?How will it be controlled?MaterialWe must use the same material due to the fact that various materials have different resistances. If I were to use a material with a high resistance then, one with a low resistance my results would become un-reliable.I will use a 26SWG Nichrome Wire (See justification in pre-tests section.) It will b e attached to a 1 metre ruler.TemperatureThe variable power-pack will be turned off after each recording has been made (refer to method), this will allow the wire to cool down so it will not affect my data.Cross-Sectional AreaAs previously mentioned in the background (with figures 1 ; 2) varying the cross sectional area of the wire (thickness) will affect the resistance and make the data collected less reliable.From the pre-tests and the fact that we did not have enough resources to vary the gauge of wire we will be keeping the Nichrome wire at 26SWGs.Current (0.5A)The current causes the wire to increase in temperature. Keeping the current low at 0.5A lowers the heating affect and ensures the resistance of the wire will not be affected. This will increase the reliability of my results.Through the use of a variable power-pack we can adjust the input of volts and maintain a constant current of 0.5 Amps for each test.Straightness of WireThe straightness of the wire affects the length o f it. If a wire with a crocodile clip on it is connected at 20cm and the wire bends, the length and resistance of the wire changes. Therefore, we must keep the wire as straight as possible, that is why we are using a ruler and some sellotape.The wire chosen (26swg) can be easily straightened along a 1 metre ruler. For that reason, we will place the wire along the ruler and connect it to either end with the use of sellotape. This will lower the chance of the resistance being affected and thus, increasing the reliability of our results.EquipmentEquipment NameJustification for useDiagramVariable Power-Pack (0-12V)The use of a variable power pack allowed me or any member of my group to manually adjust the voltage input through the circuit in order to control and manipulate the number of amps being transmitted in our circuit, in our case it allowed us to keep the number of amps to 0.5 in order to make our experiment reproducible.Digital AmmeterUsing a digital ammeter allowed for much mor e precise readings of the amps present in the electric current with only a +/- 0.1 area for mistake in comparison to the traditional ammeter which has an area for error of +/- 0.5 as it requires the use of the naked-eye to record the readings. For that reason the digital ammeter was used in the experiment.Digital Volt MeterDigital voltmeters give a numerical display of voltage to 2 decimal places by use of an analog to digital converter, which lowers the margin of error to +/- 0.1 whereas, an analog voltmeter moves a pointer across a scale in proportion to the voltage of the circuit. This requires the use of the naked-eye and increases the margin of error to +/- 0.5. For that reason the digital volt meter was used in the experiment.100cm Ruler with wire onThe range of the length of wire was 25-95cm, the use of a 100cm ruler allowed us to easily place the wire straightly upon it and easily record the measurement of length in comparison to laying down four 30cm rulers which would have increased the error of margin in the reading of various lengths such as 35cm or 75cm.26swg Nichrome WireFrom the pre-tests we found that this wire could be easily straightened along the 1 meter ruler whereas the 36swg piece of wire could not which meant the resistance was not affected as there were next to no bends in the wire. Also, it was not as susceptible to heat as the 20swg wire which when heated would have caused the resistance to increase due to the more energy in the circuit, which would have increased the chances of collisions between free electrons and atoms.2 x Crocodile ClipsCrocodile clips allow us to connect the wires to the circuit (creating a complete circuit) in a safe manner which lowers the risk to the people involved in the experiment.4 x WiresUsing these in our experiment is essential. These allow us to connect each piece of equipment together for example; the voltmeter to thee variable power-pack.Method1. Clear your workspace, this will make your working area safe for you and your class mates and ensure that there are no accidents.A) Place chairs/stools under desks.B) Clear the desks of paper, books, bags etc. and simply have a pen and results table in order to record your results (following the steps below you will find out how to create a suitable results table).2. Gather all the necessary equipment, as previously mentioned. The Equipment is necessary in order to undergo the experiment because if all equipment is not used or set up accordingly then the data will not be reproducible.3. Set the equipment up as shown by the circuit diagram below, following this circuit diagram will increase the similarity to our experiment therefore, increasing the reliability of the results collected.4. Now that the equipment is set up, ensure that the variable power-pack is turned off with the adjustable voltage dial is turned to 0, this is to make sure that the wire does not heat up before acquiring data as the temperature will affect the resistance a s previously mentioned in the Background section of this document.5. Create a results table with the following headings in a similar order. You should also include the suitable range of lengths at which you will be moving your crocodile clips in the appropriate column (wire length(cm)) For this experiment I chose to use the range of lengths; 25cm-95cm.Wire Length (cm)Current (A)Cross Sectional Area (swg)Voltage (V)Resistance (R = V/I)Test 1Test 2Test 3Average6. Place one wire with a crocodile clip on it at one point on the 1 metre ruler, then place the other wire with a crocodile clip connected at another point 25cms apart.7. Turn the variable power-pack on, adjust the voltage dial until the digital ammeter has a constant reading of 0.50A.8. Record the amount of volts as displayed on the digital volt meter on your results table. for example, 1.289. Once recorded, turn the variable power-pack off and wait a reasonable amount of time so that the wire has sufficiently cooled down, this is because if the wire increases in temperature the resistance will be effected as previously mentioned in the Background section. This could result in our results being less reliable and giving me less confidence in my conclusion.10. Then, remove one wire and increase the length to 35cm. Repeat steps 7-9. Continue to do this until you reach the length 95cm. Once you have recorded the reading for 95cm repeat the above stages 2 more times until you have repeated the range of 25-95cm with 10cm intervals 3 times.11. Now that you have repeated each length 3 times you must work out the average voltage for each length, do to this you simply add all three results together and divide them by 3 (the number of test carried out). For example, I have three results 1.15, 1.17 and 1.12, these add up to make 3.44, then I divide 3.44 by 3 to get a mean average of 1.15.12. With the average, we can calculate the resistance In the circuit. To do this, we must multiply each average voltage by 2, this is because when using the equation for resistance we will get R = V/0.5 which is the equivalent to the average voltage multiplied by 2. Continue to do this for each length until you have done all 8 sets of data.Pre-TestsChange Gauge (SWG) of WireLength of Wire (cm)Cross Sectional Area (SWG)Current (A)Voltage (V)Average (V)Test 1Test 2Test 325160.501.911.911.921.91100160.507.747.767.777.7625200.500.070.070.070.07100200.500.170.170.170.1725260.500.130.140.130.13100260.500.420.420.420.4225360.5011.021.021.02100360.503.693.763.733.73From viewing these results we can interpret the temperatures created when the current of 0.5Amps has been placed through the circuit. For example, when viewing the data for the 16SWG wire we can see that the voltage at 100cm is 7.76V, this high voltage could be due to the low cross sectional area of the wire and because of this the temperature would be much higher in comparison to that of the 26SWG wire which has a voltage of 0.42V at a length of 100cm. Due to the increase in temperature present in the wire the data cannot be counted as reliable as the heat of the wire affects the resistance and therefore, the voltage read by thee voltmeter (for further explanation on resistance and the cross-sectional area of a wire see the Background section).Also, going up a gauge of wire, at 20SWG does not provide reliable results in my opinion. This can be seen with the results at 25cm which has an average voltage of 0.07V and the other at 100cm which has an average voltage of 0.17V. The reading at 100cm was expected to be approximately 0.28V and as you can 0.17V is over 0.1V under the predicted result. This could have occurred for multiple reasons. For example, the wire may not have been straight and due to this the resistance may have been affected thus, resulting in the lower piece of data collected.Finally, from the data gathered and the selection of resources used in this pre-test I can come to the conclusion that carrying out my final exper iment in this manner would not be the best way to collect reproducible data, this is due to multiple reasons; one, there are simply not enough different pieces of wire with varying cross-sectional areas to carry out the experiment to satisfactory standard and two, the increments used are not very good for plotting a graph or conveying accurate results, the increments used in this pre-test were a follows 4, 6, 10. This is not an even increase and would give me less confidence in my results when it came to plotting them on a graph.

Dilution Calculations From Stock Solutions in Chemistry

Dilution Calculations From Stock Solutions in Chemistry If youre working in a chemistry lab, its essential to know how to calculate a dilution. Review Dilution, Concentration, and Stock Solutions A dilution is a solution made by adding more solvent to a more concentrated solution (stock solution), which reduces the concentration of the solute. An example of a dilute solution is tap water, which is mostly water (solvent), with a small amount of dissolved minerals and gasses (solutes). An example of a concentrated solution is 98% sulfuric acid (~18 M). The primary reason you start with a concentrated solution and then dilute it to make a dilution is that its very difficult (sometimes impossible) to accurately measure solute to prepare a dilute solution, so there would be a large degree of error in the concentration value. You use the law of conservation of mass to perform the calculation for the dilution: MdilutionVdilution MstockVstock Dilution Example As an example, say you need to prepare 50 ml of a 1.0 M solution from a 2.0 M stock solution. Your first step is to calculate the volume of stock solution that is required. MdilutionVdilution MstockVstock(1.0 M)(50 ml) (2.0 M)(x ml)x [(1.0 M)(50 ml)]/2.0 Mx 25 ml of stock solution So to make your solution, you pour 25 ml of stock solution into a 50 ml volumetric flask. Dilute with solvent to the 50 ml line. Avoid This Common Dilution Mistake Its a common mistake to add too much solvent when making the dilution. Make sure you pour the concentrated solution into the flask and then dilute it to the volume mark. Do not, for example, mix 250 ml of concentrated solution with 1 L of solvent to make a 1-liter solution!

The Duty to Intervene in Conflicts Around the World Essay

The Duty to Intervene in Conflicts Around the World - Essay Example France, Belgium, the United States, and even the United Nations, did not intervene to stop the slaughter, and instead, they decided to pull out 90% of their peacekeeping soldiers and to evacuate all white people from Rwanda (â€Å"Genocide in Rwanda†; Rwanda Genocide Documentary). Some people believe that the U.S. and other powerful nations do not have a duty to intervene. We have a duty to intervene in conflicts around the world because it is right to do something that should be a universal law and because to do so without expecting anything in return is to treat people as ends in themselves who have moral worth. At the same time, the Universal Declaration of Human Rights declares that member states have a duty to promote universal human rights and freedoms. Moreover, I believe that it is wrong to just leave and look the other way or to not do anything, like what happened to Rwanda, because these are innocent people who are unarmed and who have no one else to protect them, no t even their government, so another government should help them out of their humanity where compassion and goodwill live in. We have a duty to intervene in conflicts around the world because it is right to do something that should be a universal law. Immanuel Kant describes in â€Å"Good Will, Duty, and the Categorical Imperative† what it means do what is good. He offers two categorical imperatives, which are commands that must be done unconditionally. The first categorical imperative is to act according to the maxim that it â€Å"should become a universal law† (152). If nations help other besieged people in other countries, this should be a universal law because it is the act of rationality to help others in dire need. It is wrong then for France, Belgium, the United States, and the United Nations to not extend help to the Tutsis whom they were aware were being systematically slaughtered.  

Nursing staffing ratio policy for the ICU department Assignment

Nursing staffing ratio policy for the ICU department - Assignment Example The policy was first implemented in the California legislature through the passage of the Bill 394. Stakeholders such as the Institute of Medicine, California Hospital Association, California Nurses Association and the Service Employees International Union combined efforts and contributed jointly to development and implementation of the nursing policy. These associations contributed significantly in the policy formation process to address a number of factors. Factors addressed comprised of inadequacy of nurses in hospitals, registration of nurses, poor results from nurses and poor patient care services (Tevington, 2011). Health care stakeholders believed that the policy would solve problems experienced in the healthcare sector. In addition, they believed the policy would increase desired patient outcomes, increase recruitment of nurses, decrease shortages of nurses and increase job satisfaction (Unruh, 2008). Currently, many legislatures in the world have adopted the nursing policy a nd others are still adopting the policy. Mandatory Nurse-Patient Ratios Policy was developed for several purposes. The nursing policy was developed in order to develop an appropriate and specific ratio of nurses to patients that would be adopted by hospital to ensure that there are adequate nurses. In addition, the policy focused on improving the patient results in hospital through employment of registered and licensed nurses in different units in hospitals (Tevington, 2011). The Mandatory Nurse-Patient Ratios Policy has a wide range of users and participants. According to Douglas (2010), users of the Mandatory Nurse-Patient Ratios Policy consist of patients, physicians, nurses, healthcare unions, medical researchers, nursing organizations and associations and state governments. The policy affects nurses, patients and hospitals directly and physicians, health unions, medical researchers and
