Factors influencing Dnata’s operation and employee performance Essay

Abstract Dnata is one of the subsidiary companies that work for Emirates airlines (Peevers 178). In order to evaluate how certain factors affect Dnata’s operations, a research was conducted on the same. The research focused on the price of oil as a factor that negatively affects the company’s performance. On the same note, the research focused on the impact of reward strategies and how it affects employee performance in relation to organization performance. This research was prompted by the fact that Dnata Company was performing poorly in finance. This led to a negative impact on the company’s performance on logistics, operations and financial management. On the other hand, the company’s employee performance was deteriorating as evidenced by a staff strike of Dnata staff members at Geneva airport in the year 2012. Such employee actions can be a bad precedence to other staff members across the globe. From the two scenarios, it is evident that the company’s performance as a global company in the airline industry was at stake. From this context, a research on factors affecting the company’s operations and employee performance was initialized. The research conducted used both qualitative and quantitative research methodologies. By administering questionnaires to the Dnata employees, the research was to understand the employees’ perspective on issues affecting the company operations. In addition, the questionnaires revealed the plight of the staff members and factors that influence their performance. By using both quantitative and qualitative research techniques, the research was done in an integrated manner. This made the data analysis easier by using descriptive statistics and analysis of the inferential data (Maxwell 133). Such data analysis methodologies are effective as evidenced when analyzing the impact of high oil prices on the Dnata’s performance. Additional techniques included the use of graphs and charts in analyzing data. On the other hand, the research on employee performance was done through open-minded questionnaires. However, the results were analyzed by use of descriptive statistics. The results of the research indicated that the fluctuation of oil price in UAE led to the slackening trend of Dnata performance between the year 2008 and 2012. In fact, as the oil prices increased, the company became vulnerable to other risks associated with high costs of operations management. In this respect, the research recommended that Dnata Company engage in outsourcing some of its operations to reduce the cost of operations.

The research indicates that employees preferred monetary rewards and better working conditions to improve on their performance (54). Employee welfare became a critical issue from the research. In this respect, the research recommendations were that the Dnata Company should use reward strategies. The result expectations of this research were that the company will avert future industrial actions through reward strategies. Moreover, the company managers will use a good employer-employee relationship to ensure that the overall organization’s performance is not affected. Both studies are fundamental in ensuring that Dnata Company is able to evaluate its performance from all dimensions. In this case, better managerial concepts to avert a financial crisis from oil prices are recommended. On the other hand, better management of employee expectations is critical in improving employee performance and averting industrial actions. Basically, all these factors are significant in evaluating the overall organization’s performance. Works Cited Maxwell, A. Joseph. Qualitative research design: An interactive approach.

Thomas Friedman and His MIT Speech: A Retrospective and an Analysis Essay

Introduction: Thomas Freedman and the MIT Milestone Celebration There is no need to introduce either Thomas Friedman, or his concept of the flat world – both seem to have gained the world recognition since recently. While the book is extremely entertaining, with a plethora of innovative ideas, each being a potential means to reinvent people’s perception of the world, it cannot match the public performance of the master of economics himself. The Organization of the Speech: An Unusual Way to Present an Idea Actually, it would be weird to expect that one of the best Times columnists would deliver his speech in a traditional boring and predictable way. Friedman throws in some jokes: “I know some of you’ve read the book, some of you haven’t – I know who you are” (Friedman 3:01), thus, creating a comfortable atmosphere, in which the complex issues of the flat world can be discussed. The given approach, however, begs the question whether the audience will be able to take the ideas conveyed by the lecturer seriously. Conclusion and What Followed It: An Unexpected Twist Ending Concluding his speech with the discussion of the current problems of the humankind evolution and the need for “being smart about the innovative things we have” (Friedman 38:13), Friedman gives his audience a lot of food for thoughts.. It would be unreasonable to assume that consumerist tendencies are necessarily bad. Instead, it will be more reasonable to introduce people to other options that are tied in with the concept of consumerism, such as creating more comfortable setting for everyday life. Delivery of the Speech: When the Style Matches the Substance Surprisingly enough, Friedman never resorted to any of the traditional antics of public speakers in his MIT speech; instead, he calmly got his point across. In many ways, this was the right thing to do, because the audience wanted him to talk honestly. Seeing how Friedman’s book featured a very honest and open approach towards the readers, the audience in the lecture hall had the rights to expect the same from the author. Analyzing the Scenarios: Freedman’s Experience One of the doubtless advantages of Friedman’s speech concerns numerous examples, which the author offers for the audience to consider, therefore, making his arguments all the more impressive. Of all the stories that Friedman shares with his audience in the MIT speech, three key examples of how flat the world can get are worth specifying and analyzing. Netscape: flattening the world to the bursting point Netscape, with its open transmission protocols, gave “two basic flatteners that changed the world” (Friedman 13:18), which were a browser and the dot-com bubble. However, it seems that Friedman still overrates the significance of Netscape. While it should be credited as the browser that allowed for the creation of Mozilla Firefox, one of the most widely used browsers, the credits for creating the first browser ever should be given to Tim Bernes-Lee and his WorldWideWeb, as known as Nexus. Therefore, Friedman raises an interesting dilemma of choosing between the invention that technically was the first discovery, and the invention that spawned further technological evolution. Get your 100% original paper on any topic done in as little as 3 hours Learn More Southwest Airlines calligraphy classes: the art of convincing With his incredible skill of telling a story, Friedman managed to turn his experience of booking a ticket at Southwest Airlines into a lesson in the flatness of the world. Emphasizing the fact that he had to change his manner of communicating with the Southwest Airlines “from vertical to horizontal” (Friedman 31:47), Friedman explained that the introduction of online facilities, such as ticket booking, had, once again, simplified the process from having the employees to fill out the ticket information to having “calligraphy classes” by making the customers fill out the forms and interacting with people representing companies. Friedman’s remark regarding the given innovation as a step forward is, actually, rather questionable. On the one hand, the idea of interacting with the company’s representatives directly gives one a pleasant feeling of being treated like an individual. On the other hand, the process going through the routine of talking to the company’s agents whenever buying or booking something quickly wears off its novelty and becomes unnecessarily tedious. Green Revolution as a necessary step in the world progress Friedman makes it evident that people, in fact, need Green Revolution as one of the key steps on the way to further progress. However, what the humankind has now is a “Green Party” – a revolution in which “no one gets hurt” (Friedman 42:06). To make the Green Revolution work, one must take more drastic measures, Friedman stresses. It is peculiar that Friedman compares the unsuccessful Green Revolution to the IT Revolution, which was “real,” as Friedman explains, because it had a tangible and not necessarily good effect on people’s lives. Yet Green Revolution seems to have failed for different reasons than the ones mentioned by Friedman. Unless its organizers had thrown a recycled, completely worn out principle of “saving the planet” into it as the motto, coming up with a more original idea instead, the idea of the Green Revolution might have caught on with people. Conclusion: A Speech Worth Being Remembered Definitely one of the most memorable performances ever given in MIT, Friedman’s speech has shed some light on the processes that are currently taking place on many levels, including economical, social and sociopolitical ones. While some of the ideas that Friedman conveyed during his performance are very arguable, there is one thing that he is perfectly right about: the world is changing fast, and people have to keep in pace with the recent tendencies. A speech to remember, the MIT performance allows evaluating the scale of “flatness” of the present-day world.

EE 453 Pennsylvania State University Simulink Audio Signal Processing Lab Report

EE 453 Pennsylvania State University Simulink Audio Signal Processing Lab Report.

Pageof 8ZOOMEE 453: Lab 1Introduction to Simulink: Audio Signal ProcessingSeptember 19, 2018OverviewThe purpose of this first lab is to familiarize the student with DSP developmentusing MATLAB Simulink. You will learn how to use the Simulink equivalents ofhardware measurement tools such as oscilloscopes and spectrum analyzers. Youwill then do some basic audio signal processing tasks, finishing by examiningsome common audio effects used in music.Each DSP workstation in the EE 453 lab is equipped with a computer withMATLAB Simulink installed, and headphones to be used so you don’t disturbother students.The software used in the EE 453 lab isSimulink, a component of MATLAB thatis a block diagram based development platform (similar to LabView). Simulinkallows for fast generation of DSP algorithms using an easy to learn drag-and-drop approach.11 System SetupBefore beginning the lab, you must make sure the system is setup as follows:•Connect your headphones to the Headphone jack on the front of the com-puter•Log on to the computer using your PSU access account.You must saveall files on your PSU W: drive. Please do not store any fileson the computer itself. It takes up hardrive space, and will bedeleted periodically. While not necessary to save the files, they will begood to have as a reference for the future labs this semester.•Download the.zipfile from Canvas containing files needed to completethe lab.2 Simulink Bench InstrumentsAs a first experiment, you will learn how to use Simulink’s spectrum analyzerand oscilloscope.1. Open up MATLAB and change the current directory to your PSU W:drive. Do this by selecting theBrowse for Foldericon located above theCURRENT FOLDER window. If you want, you may create an EE 453subdirectory on your W: drive by selecting theNew Folderbutton in theselection window.2. Typesimulinkin the MATLAB command window. You will want to opena new blank model. Once this window is open, notice the red, white andblue squares in the toolbar. This is how you access theSimulink LibraryBrowser.3. Enlarge this window so that it covers about half of your screen, but don’tcover up theSimulink Library Browserwindow. You will be dragging/-dropping blocks from various libraries into this model window to createyour various DSP algorithms. You are now ready to start building yourfirst model.24. The first thing is audio sources that will act as inputs to the model. IntheSimulink Libary BrowserselectDSP System toolbox→Sources→From Multimedia Fileand drag this into the model window5. After adding the block, you must set its parameters. This can be doneby double clicking on the block. Do this for theFrom Multimedia Fileblock, underFilenamebrowse until you find the audio file ”Track1.wav”downloaded from the canvas website. Accept the rest of the defaults.6. In order to play the audio file, you must add another block from the librarybrowser. The needed block isDSP System toolbox→Sinks→AudioDevice Writer. Again accept the defaults. Keep in mind the blocks mustbe connected together by clicking on the port on the block, and draggingto the next block. Test the system so far by clicking the green play buttonat the top of the Simulink file.7. We are now ready to actually analyze some signals. The first thing weare going to do is create some pure sinusoids in MATLAB. A template isgiven below:%%S c r i p t t o c r e a t e a s i n u s o i d%%I n p u t sFs = 8 0 0 0 ;%S a m p l i n g Ratef r e q = 8 0 0 ;%D e s i r e d t o n e ( Hz )f n = ’ 800Hz ’ ;%F i l e n a m eA = 0 . 1 ;%M a g n i t u d e o f s i n u s o i dT = 3 ;%L e n g t h o f s i g n a l ( s )%%S o u n d f i l et = 0 : 1 / Fs : T ;y = A∗cos( 2∗pi∗f r e q∗t ) ;a u d i o w r i t e ( s t r c a t ( f n , ’ . wav ’ ) , y , Fs ) ;Answer Q1 and Q2 on your worksheet8. Use the script above, or your own version, to create two discrete sinusoidswithωc= 0.2 andωc= 0.8. Use a sampling rate ofFs= 8000.9. In the Simulink window, we are going to place a Spectrum Analyzer inparallel with the Audio output. As the name would imply, a spectrum3analyzer allows the user to view the frequency content (spectrum) of asignal. The spectrum analyzer is found inDSP System toolbox→Sinks→Spectrum Analyzer. The spectrum analyzer can be connectedin parallel by connecting the output port to the middle of the line betweenthe audio input and outputs.10. View the two sinusoids through the spectrum analyzer (run the simulinkfile). Verify that the peaks of the signals are at the expected frequencies.This can be done by using the file menus of the spectrum analyzerTools→Measurements→Peak Finder.Call your TA over to verify that this program is working.YourTA will sign your lab worksheet.11. Without changing the two continuous frequencies, change the samplingrate in the sinusoid creation script toFs= 4000. Pass these modifiedsinusoids through the spectrum analyzer.Answer Q3 and Q4 on your worksheet12. You will now implement an echo effect, and analyze how feedback canchange the stability of a system. In order to view this phenomenon, wewill be using the oscilloscope.13. Remove the spectrum analyzer from the current simulink file (or create anew one, keeping the audio input and output (I/O).14. The oscilloscope can be found inDSP System toolbox→Sinks→Time Scope.15. Change the input audio signal toEchoSample.wav. This audio file issampled at the standard CD sampling rate of 44.1 kHz.16. In order to implement an echo sample, we are going to want to implementthe difference equationy[n] +Ay[n−δ] =x[n]. The difference equationrequires three blocks:•Summing Block:Simulink library→Math Operations→Sum•Gain Block:Simulink library→Math Operations→Gain•Delay Block:DSP System Toolbox→Signal Operations→Delay417. To implement the difference equation, the sum block must be placed be-tween the input and output I/O. The wire connecting the sum to theoutput must then be fed into the delay block, followed by the gain block,and back into the sum block. In may be helpful to rotate the blocks, inorder to have them point in the correct direction. This can be done viaRight click + Ctrl + R.18. Double-click on the delay block and set the following parameters. Therest can be left as default.•Delay Length: 4410019. Double click on the Gain block and set the parameters. The rest can beleft as default.•Gain: 0.720. Run simulink, and observe the output. Then modify the following param-eters:•Delay (samples): 10000•Gain: 1.1Answer Q5 and Q6 on your worksheetCall your TA over to verify that this program is working.Your TA willsign your lab worksheet.53 Audio Signal ProcessingThis audio signal processing portion will focus more on just using the noramlMATLAB functionality of scripts and functions.1. For this first part of the experiment, you will implement a chirp signalusing MATLAB.A sinusoidal waveform can be described asx(t) =sin(φ(t)). The instanta-neous frequency is taken to be the derivative of the phase,f(t) =12πdφ(t)dt.A linear chirp is whenf(t) =f0+kt.2. A chirp signal is easily identified using a graph called a spectrogram. Aspectrogram gives a plot of frequency on the y-axis, and time on the x-axis.3. The chirp you implement should be as follows:t = 0 : 1 / 1 e 3 : 2 . 7 ;y = c h i r p ( t , 0 , 1 , 2 5 0 ) ;s p e c t r o g r a m ( y , 2 5 6 , 2 5 0 , 2 5 6 , 1 e3 , ’ y a x i s ’ ) ;Answer Q7 on your worksheet4. In this part of the lab, you will create two sinusoids, and find what happenswhen the two sinusoids are added together. Create two sinusoids, and addthem together in the same script, so they have the exact same phase i.e.y1(t) =sin(ω1t)y2(t) =sin(ω2t)y(t) =y1(t) +y2(t)5. SetFs= 1080,f1= 510 andf2= 530.6. Listen to the output usingsoundsc(y,Fs)in MATLAB7. Now changeFs= 1040, and listen to the differenceAnswer Q8 and Q9 on your worksheetCall your TA over to verify that this program is working.YourTA will sign your lab worksheet.68.
