Managment - Case Study Example These new values were identified by him as they were in keeping with the current competitive and changing environment to which airlines around the world were being forced to adapt if they wished to survive. This case clearly shows that even if you have the potential and capital, if work is not organized properly, the company cannot survive. This is what this company did. Motivation and redesigning work organization structure are keys to success here. Using James Hoogan as an example of effective leadership, this essay will argue that effective leadership is a combination of strategic and operational leadership values rather than a one dimensional energizing or motivational leadership. Leadership that combines the strategic and the operational is the key requirement to turning around an organisation that is in danger of going under, because there is a lot more at stake in such a company than just a workforce that is not motivated or skilled enough. There are faulty strategies that need to be identified and isolated and changed operational values that need to be put in place to fit the strategy outlined. There is no room for experimentation as in many cases the situation is a do or die one. These situations require leaders who can do a lot more than just motivating and training the workforce with new skills. Very often motivation falls in place once the workforce sees new procedures in place and becomes convinced of the changed st rategies. Research indicates that the leadership model suggested by Kenneth Blanchard is the best for effective leadership. With competition getting stronger, leadership is the key to the success or failure of any company as the many mergers, takeovers, chapter 11s, lay offs and the few hard won success stories of the corporate world will bear out. Those companies that have the right leader in the right place at the right time manage to scrape through after resorting to stringent measures and in almost all cases after bringing in a complete change in strategy and work culture, almost a revolution. Many companies even move on to be highly successful and competitive, because their changed business strategy makes them adaptable to a changed business environment. The right leadership is crucial to ensure that this transition from a floundering business to a successful one happens smoothly and successfully. The Gulf Air story is one of a successful transition which happened only because the management of the airline was pragmatic enough to appoint James Hoogan as CEO the right time; the right man at the right time. Three years after he took over the story was a completely different one, he gave Gulf Air a completely new face, quite literally because they even sported a new uniform. In considering the role of leadership in the management of a company, this paper will compare the much acclaimed Jack Welch model with the model given by the Kenneth Blanchard Company, a model that is more acceptable today. The most successful and known model of leadership n corporate literature was given by Jack Welch which he developed with the intention of revolutionizing GE and turning it into the most competitive company in America. He himself led GE for over 20 years and during that tenure he succeeded in transforming it completely. The model of leadership given by him defines a leader as one who possesses the 4 qualities

Suffering from depression Essay Example for Free

Suffering from depression Essay In one of the first workshops we initially produced a brainstorm of ideas as to why people may be institutionalised. Below I have listed a selection of illnesses which were brainstormed.  Medication non-compliance: Not following treatment and/or not taking medications as prescribed.  Cognitive impairment: Defined as unusually poor mental function, associated with confusion, forgetfulness and difficulty  Depression: A psychiatric disorder showing symptoms such as persistent feelings of hopelessness, dejection, poor concentration, lack of energy, inability to sleep, and, sometimes, suicidal tendencies Incontinence: Often used to refer to a lacking in moderation or self-control, especially related to sexual desire.   Everyone worked in pairs where one of us had been put into the institution by the other. Holly and I worked together, we decided I would be the character in the institution and I was then hot-seated. I decided I was a thirty-five year old woman who had been left by her husband and as a result of this, tragically suffering from depression. As a pose to helping me herself, Holly carelessly decided it was best to leave me in an institution, not knowing this sudden change in surroundings, faces and routine would in fact provoke my illness, leaving me worse than before. When brainstorming ideas as to why people may be institutionalised, depression seemed an obvious and popular idea. This influenced my reasons for rendering my character depressed. After we were hot-seated our teacher asked us questions about the characters we had created, I found the hot-seating helped tremendously when trying to understand and form my character, thus making it easier to answer questions about her. As I was able to understand my character through the hot-seating, I found I was able to form a deeper connection with her; I believed this would significantly help my portrayal when acting her character. We then created a duologue. This helped me further develop my character as it allowed me to see how she reacted when left face-to-face with Holly, through improvisation. It was clear from our characters opposing behavior towards one another that our relationship had been damaged due to the institution. Not only had my condition worsened but Hollys cold nature penetrated the already bad atmosphere between us making everything more awkward.Holly visits the institution to see if my condition has improved. This is the first time in two years she has visited and my hostile behavior towards her shows I am affected by her lack of visits. When she enters my room I am sitting in the corner, dribbling, rocking and the lights are off; she is horrified my depression has worsened and tries to leave immediately. Quickly I get up and run to the door, barricading it. I ask her why she put me here and left me for two years, followed by my monologue. In reply to this Holly performs her monologue explaining my depression was affecting her and everyone around me. Furiously, Holly pushes me aside and runs out of door, I am left crying on the floor in a ball, screaming and shouting why did you do this to me, scene cuts here. FINAL PERFORMANCE I found the final performance ran successfully, Holly and I remembered our lines and our stage directions; this, I thought, played a big part in the overall success of our performance. I believe my character came across well to the audience as the general feedback was positive- this showed the audience was able to identify with and understand my characters feelings and difficulties. Although the majority of the performance went well I, however, believe there is always room for improvement. Holly and I could have incorporated a flash back at the beginning of the scene, showing the audience the day I was put into the institution. I think this may have furthered the audiences understanding of my character and make the fact my condition had not improved clearer. This would not have only benefited the audience, but myself. By developing the scene in this way, I would have been able to also develop my character further on a whole, learning more about her.

Round-trip time (rtt)

Round-trip time (rtt) RTT: Round-Trip Time (RTT) can also be called as round-trip delay. It is to calculate how much time required for sending a packet or signal pulse from one source to a specific destination and comes back to the same specific source. RTT is one of the several factors that affecting latency and the time between the request for data and also the complete return or display of that data. RTT can range between a few milliseconds under some ideal conditions to several seconds between points under adverse conditions. Estimated RTT plus can be defined as safety margin. It is the estimated value of RTT that is based on the combination of current RTT and the past RTT. EstimatedRTT = (1- a)*EstimatedRTTlast + a*SampleRTT Large variation in Estimated RTT means larger safety margin. To calculate the DevRTT we need to estimate how much Sample RTT deviates from Estimated RTT i.e., DevRTT = (1-b)*DevRTTlast +b*|SampleRTT-EstimatedRTT| (typically, b = 0.25) Segment Sample RTT Estimated RTT DevRTT Time Out Interval 1 130 130.00 130.00 650.00 2 138 131.00 99.25 528.00 3 122 129.88 76.41 435.50 4 124 129.14 58.59 363.50 5 131 129.37 44.35 306.77 6 139 130.58 35.37 272.05 7 139 131.63 28.37 245.10 8 121 130.30 23.60 224.71 9 134 130.76 18.51 204.80 10 127 130.29 14.71 189.12 11 267 147.38 40.93 311.12 12 139 146.33 32.53 276.47 13 126 143.79 28.85 259.19 14 134 142.57 23.78 237.68 15 141 142.37 18.18 215.08 16 137 141.70 14.81 200.93 17 291 160.36 43.76 335.42 18 123 155.69 41.00 319.68 19 134 152.98 35.49 294.95 20 139 151.23 29.68 269.95 21 141 149.95 24.50 247.94 22 142 148.96 20.11 229.41 23 139 147.71 17.26 216.77 24 122 144.50 18.57 218.79 25 123 141.81 18.63 216.34 26 143 141.96 14.23 198.90 27 215 151.09 26.65 257.70 28 134 148.95 23.73 243.87 29 122 145.59 23.69 240.36 30 134 144.14 20.30 225.35 Table 1 A premature retransmission timeout occurs if there is no packet or signal loss or if the lost packet or signal can be captured by fast retransmission mechanism. With contrast, over estimation of RTT will lead to late retransmission timeout, in that case, if there is a loss and which cannot be captured by the fast retransmission mechanism. Therefore, it is crucial to have a Retransmission Timeout (RTO) value for TCP performance which is an equilibrium point in balancing between both the above cases. Note: RTO must be smaller than RTT. Following are the few algorithms which help in setting the retransmission timeout Ludwig and Katz propose the Eifel algorithm to eliminate the unnecessary retransmissions that can result from a spurious retransmission timeout. Gurtov and Ludwig present an enhanced version of the Eifel algorithm and show its performance benefits on paths with a high bandwidth-delay product. Ekstrand Ludwig proposes a new algorithm for calculating the RTO, named the Peak-Hopper-RTO (PH-RTO), which improves upon the performance of TCP in high loss environments. RFC 3649 proposes modification of TCP congestion control that adapts the increase strategy and makes it more aggressive for high bandwidth links (i.e. for large window sizes) Even if there is no packet loss in the network, windowing can limit throughput. Because TCP transmits data up to the window size before waiting for the packets, the full bandwidth of the network may not always get used. The limitation caused by window size can be calculated as follows: where RWIN is the maximum receive windows size and RTT is the round-trip time for the path. At any given time, the window advertised by the receive side of TCP corresponds to the amount of free receive memory it has allocated for this connection. Otherwise it would take the risk to have to drop received packets by lack of space. Unrelated to the TCP receive window, the sending side should also allocate the same amount of memory as the receive side for good performance. That is because, even after data has been sent on the network, the sending side must hold it in memory until its has been acknowledged as successfully received, just in case it would have to be retransmitted. If the receiver is far away, acknowledgments will take a long time to arrive. If the send memory is small, it can saturate and block emission. A simple computation gives the same optimal send memory size as for the receive memory size given above. Packet loss When packet loss occurs in the network, an additional limit is imposed on the connection. The limit can be calculated according to the formula (Mathis et al.): where MSS is the maximum segment size and Ploss is the probability of packet loss Below table shows the theoretical maximum sustained TCP throughput 135 kbits/sec at 1 second RTT 225 kbits/sec at 600 millisec RTT (typical satellite RTT) 449 kbits/sec at 300 millisec RTT 1200 kbits/sec at 100 millisec RTT (typical domestic Internet RTT) 1780 kbits/sec at 60 millisec RTT 2800 kbits/sec at 30 millisec RTT 4510 kbits/sec at 10 millisec RTT (typical within a city) In order to set the ACK timer we need to know how large the ACK timeout value should be. It can be too short or too long. Too short > premature timeout > extra retransmission Too long > slow reaction to loos > poor performance For this we need to have the timer longer than RTT, for this we need to estimate RTT by measuring the time from a segment transmission until the receipt of ACK which is nothing but Sample RTT. For this we need to ignore retransmissions and measure only one segments RTT at a time. By doing so, the sample RTT will vary and we can compute an average RTT based on the several recent RTT samples. Timeout = Estimated RTT + 4*DevRTT The probability of premature retransmission timeout is P1 = P[RTO < RTT] ((1-p) W + (1-(1-p) W) (1-3/W) ) ≈ P[RTO < RTT] (1-3/W 2) ≈ P[RTO < RTT] The throughput degradation due to this event is: L1 = WlogW. During the slow start ph.ase we can observe, TCP sends at most W packets. We obtain that the expected output degradation result to premature retransmission timeout is: P1.L1 = P[RTO

Investigating Resistances of Wires :: Papers

Investigating Resistance's of Wires Aim: To investigate different resistances of wires to see which has the most resistance and which shows the least resistance. I will be looking at resistances affected by the length of wire. Variables I could change: I had the choice of several variables to change such as length, cross sectional area, material and temperature the experiment is conducted at. Prediction: I believe that by increasing the wire's length it would increase the resistance. Therefor by decreasing the length it would also decrease the resistance. I also believe that the rate of the increasing resistance will be directly proportional to the length so if the length were doubled the resistance would also double. I think the graph will look like this: Reason: The property that transforms electrical energy into heat energy, in opposing electrical current, is resistance. A property of the atoms of all conductors is that they have free electrons in the outer shell of their structure. As a result of the structure of all conductive atoms, the outer electrons are able to move about freely even in a solid. When there is a potential difference across a conductive material all of the free electrons arrange themselves in lines moving in the same direction. This forms an electrical current. Resistance is encountered when the charged particles that make up the current collide with other fixed particles in the material. As the resistance of a material increases so to must the force required to drive the same amount of current. (Information found on a GCSE Physics website) Ohm's law: In1826 Georg Ohm discovered that the current flowing through the wire is proportional to the potential difference across it (providing the temperature stays the same.) 'Proportional' means if you double the potential difference the current is doubled (this information was found in GCSE Physics for you text book) Current through the wire [IMAGE] Amps Volts

Conventional Cytogenetic Report

This report is studying about conventional cytogenetic, and we will focus on a technique called ‘karyotyping’. This repot is going to introduce about the definition, the history and the improvements of karyotyping made before, what is the process and the working principle of this technique and also how if can be applied in our daily life. Karyotyping is a test to examine chromosomes in a sample of cells, which can help identify genetic problems as the cause of a disorder or disease. The term ‘karyotyping’ is come from ‘karyotype’, which is the characteristic chromosome complement of a eukaryote species.The preparation and study of karyotypes is part of cytogenetics. In the middle and late 18th century, scientists were aware of the presence of chromosomes but had difficulty studying them because of their extremely small size. Chromosomes were first observed in plant cells by a scientist called Karl Wilhelm von Nageli in 1842, but since the sample s they took had small chromosomes. After the development of genetics in the early 20th century, when it was appreciated that the set of chromosomes, the karyotype was the carrier of the genes.Another scientist Levitsky seems to have been the first to define the karyotype as the phenotypic appearance of the somatic chromosomes, in contrast to their genic contents. It took until the middle 1950s until it became generally accepted that the karyotype of humans included only 46 chromosomes. Rather interestingly, the great apes have 48 chromosomes. Human chromosome 2 was formed by a merger of ancestral chromosomes, which reducing the number. Investigation into the human karyotype took many years to settle by two famous scientists: Hans von Winiwarter and Theophilus Shickel Painter.Hans von Winiwarter examined normal human diploid cells to try and define the number of chromosomes that humans have. In his time, guesses ranged from 16 to 36. He used the most powerful microscopes available in his day in one of the first accurate karyotyping attempts, and counted specifically between 46 and 49 chromosomes in his samples in 1912. He concluded that females had two X chromosomes and males had only one X chromosome and no Y chromosome. Theophilus Shickel Painter in 1922 was not certain whether the diploid number of humans was 46 or 48, at first favouring 46.He revised his opinion later from 46 to 48, and he correctly insisted on humans having an XX/XY system. And there are two advanced skills in karyotyping. The first one is Single-Nucleotide Polymorphism (SNP), this method is going to investigate the use of virtual karyotypes for diagnostically challenging renal epithelial tumors. First is to evaluate 25 archived renal neoplasms where sub-classification could not be rendered based on morphology and other ancillary studies. Then it will generate virtual karyotypes with the Affymetrix 10 K 2. 0 mapping array platform and identify the presence of genomic lesions across all 22 autosomes.The second one is Comparative Genomic Hybridization (CGH), it is going  to scan the entire genome for variations in DNA copy number. Total genomic DNA is isolated from test and reference cell populations, differentially labeled and hybridized to metaphase chromosomes or DNA microarrays. The relative hybridization intensity of the test and reference signals at a given location is then proportional to relative copy number of those sequences in the test and reference genomes. The increases and decreases in the intensity ratio directly indicate DNA copy-number variation in the genome of the test cells.
