Managing Change at Faslane Case Study Essay

Managing Change at Faslane Case Study Essay Introduction In 2002, the HM Naval Base Clyde (Faslane) submarine base transitioned from being under the direct control of the MOD (Ministry of Defence) to a private company called Babcock International. With these substantial transitions, it was necessary for Babcock to perform change management in order to smooth over the transition, as well as improve performance, which was lackluster enough to demand the change in leadership. Both supervisors employed different change styles and levers of change in their revamping of the operations of Faslane, to rousing success. 1 In relation to sections 14.2.1 and 14.5, what is the type of change being pursued at Faslane? As Faslane, the change was to transfer much of the responsibility and accountability in fact supervision of the naval base from the Ministry of Defence (MOD) to Babcock Marine, a part of Babcock International. This was an instance of a military branch permitting a private sector company to oversee the operations of a naval base. The change was effectively from a functional structure (where individuals had a specialized set of tasks) to a bureaucratic structure (moving towards a more corporate entity, with supervisors and standardization). 2 Describe the change styles of John Howie and Craig Lockhart. The use of a consultative, coercive change style was typical of the way John Howie ran Faslane. John Howies management change style involve the use of consultation from people within their company who had experienced changes just like what was happening at Faslane. Howie focused greatly on changing management structure to use money more effectively, tracking any and every change through strict documentation. This allowed for a two-week review period of each change to see if it was effective overall. The goal was to change the people and their behaviors on a daily basis, in order to determine exactly how to provide the biggest changes. Management changes were implemented early, which was later followed by changes in personnel. As opposed to Howie, his successor seemed much more collaborative in his change management style. In the case of Craig Lockhart, he implemented a performance scorecard in order to measure outputs this left the specifics of job performance and business change management effectiveness open to everyone in the company. This provided additional accountability, thus creating incentive for these changes to be implemented more readily. Event in the tent sessions were held, with discussions being held throughout the day in order to get the opinions from the workforce as to how the changes to Faslane were going over. Honesty was another tactic; by allowing further transparency and admitting when things were going badly, the workers trusted the executives more. Allowing customers to create teams and departmental business plans created further integration within the workforce, and increased customer satisfaction. 3 What levers of change are being used [see section 14.4J? What others could be used and why? Several levers of change were implemented in the corporate takeover of Faslane by Babcock Marine. Accountability and relationships were the primary means of change that the heads of this company used. First, a communication plan was put in place by both Howie and Lockhart; these involve the use of structured methods of communicating between supervisors and employees. The event in the tent sessions, as well as the consultation that Howie had with other Babcock employees to get their feedback on the changes, are evidence of a communication plan, as are the performance scorecards. Coaching was also used to facilitate the relationship lever of change; this involves the cooperation and participation of the direct supervisors in the work lives and communication of employees. Lockharts event in the tent sessions most definitely qualify under this type of intervention, as employees felt free to come up to him with questions or suggestions, which he would take seriously. One lever of change that could have helped immensely is using resistance management. While there were many changes taking place throughout the base, one particular aspect of the change that seemed to not be addressed was to curb peoples fears about potential negative change. This can often result in resistance to the change, thus hampering productivity and progress. While this problem seemed to be minimal, there was talk by Howie of a lack of incentive to come up with a change that might mean someone loses their own job. With effective resistance management, these potential issues could have been curbed more readily. 4 Assess the effectiveness of the change programme. The change programme started by Howie and continued by Lockhart seems to have been incredibly effective; the integration of customer and businessman in the creation of business plans seems to have taken off, as 2010 saw Faslane becoming the home base for the entire submarine fleet of the United Kingdom. With that unique change, thousands of jobs are expected to be created. Given the potential for job expansion and job creation, it is safe to say that the methods used to work together and bring about effective change within Faslane worked brilliantly.

The Effects of Visual Distraction on Reaction Time Research Paper Example

The Effects of Visual Distraction on Reaction Time Paper Overall, distraction can affect human reaction time and this coincides with previous findings (Lee et al 2001). Introduction Human reaction time can be affected by many factors, one such example is distraction. Literature suggests that distraction can affect a persons ability to react to a particular stimulus, In the sense that it increases the reaction time (Lee et al 2001). The Impact of distraction on reaction time carries huge significant to the current society In terms of the dally activities which are performed by majority of the people, such as driving. The use of technology whilst driving has been re-assessed and more recently the use of sat Nava has been a debatable topic (Dave Evans, 2012). More pacifically, evidence suggests that when one looks directly at an object, their peripheral vision becomes slightly impaired and this affects a persons reaction time (Brenner and Welfare, 1980). Also the use of hands-free phones whilst driving results has a negative effect on attention and does not improve reaction time performance (Horror and Wickers, 2006), (Hendricks and Sweetie, 2007). Distraction is a common cause of accidents (NATHAN, 2009). The need to reduce potential threats to others as a result of reduced reaction time points to the need of further research into the effects of distraction. Visual distraction can affect drivers reaction time and with Increasing number of Len- car technologies available, reaction time Is likely to be affected. Previous experiment investigated the effects of in-car technology perceived as visual distraction using a calculator Dates experiment on ventricle Drawing Elegance Ana control (Karee et al, 2012).

The visual pathway may be responsible for affecting human reaction time (Ghent, McCormick, 2010). Research showed that visual stimuli presented to different regions of the eye produced different reaction times (Brenner and Welfare, 1980). In addition to this, it has been found that drivers with experience of being exposed to several visual stimuli have shown to have a faster reaction time than inexperienced drivers (Constantinople et al, 2010). This suggests that the human brain no longer finds a certain stimuli as a distracted and is able to process it effectively (And et al, 2002). Therefore, studying the common response to visual distraction, looking for a potential mineral pattern and its consistency in human reaction time is needed. This study will focus on the effects of distraction brought by visual stimuli on human reaction time. The distraction task will involve a sensory visual background for the participant to view whilst also keeping an eye out for the red dot flashing on the centre of the screen. Upon noticing a red dot, the individual will have to respond by pressing the space bar. According to previous findings, visual stimuli should increase reaction times of an individual. Method Design A within-participant two-tailed experimental design was used to explore the effects of castration on reaction time. Participants were randomized to one of two conditions of the independent variable (V); either to perform the distraction task first or the non-distraction task. Randomization of the participants was decided by using the random number table to allocate participants into group 1 or group 2. The dependent variable (DVD) was the speed taken (seconds) to complete the reaction task. Participants The participants were a convenience sample of 55 young adults (less than rays age) which comprised of both males and females studying at Nottingham Trend University, England. Among them, 31 were female and 24 were male. Their age ranged between 16 and 62 years old and the age mean was 29,98 years old. None of the participants had previous knowledge of similar visual tasks. No specific incentive was used. Material The study was examining reaction times using a computer based stimulus. The tool used to measure reaction time among young adults was an online test developed by Ennobler Learner Foundation (http://www. Learner. Org/courses/neuroscience/ interactive/reaction. HTML). An information sheet was presented to the participants explaining the experiment. Procedure Participants were asked to read the information sheet and provide written informed consent. All the pages of the online test were opened and ready to use. Participants were given one trial test before commencing onto the recorded test. Participants were required to press the space bar on the computer/laptop using their dominant hand every time a red dot flashed on the screen. In the distraction task, visual stimuli were presented in the background and participants were required to press the space bar when seeing a red dot flash. Three tests were carried out for the control and experimental task. Results were recorded onto a data sheet. On completion of the experiment the participants were then thanked and debriefed. Results For the non-distraction condition (Rotor), the mean was 0. 05 and the median was 0. 298 whether for the distraction condition (RD) the mean it was 0. 331 seconds and the median 0. 330 In the non-distraction condition, scores ranged from 0. 225 to 0. 544 whereas on the distraction condition the minimum was 0. 233 and the maximum score was 0. 497. A significant difference was found between the reaction test study with distraction and without distraction t(54)= 5. 0; p 0. 001). Discussion The resul ts indicated that there is a significant difference between the reaction time with visual distraction and non-distraction. The average reaction time with visual distraction is 0. 026 seconds longer than in the non-distraction task. In addition, the difference between the two variables was considered replicable to most of the population. It is coherent with the previous studies that suggest that sensory distraction increased reaction time. In the experiment, the main visual stimulus was presented in the direct vision of the artificial (red dot in the centre of the computer screen) and other visual distraction cues were moving around the red dot involving peripheral vision. As Brenner and Welfare (1980) concluded, participants concentration on the centered stimulus might have impaired the participants peripheral vision which resulted in a load in processing the visual stimuli and consequently in a delay in reaction time. Ghent and Mnemonic (2010) suggested that a visual disruption occurs between two visual systems, the ventral and dorsal pathways, causing blank display. The ventral pathway detects object (identical features such as color or shape) and the dorsal pathway detects location (motion features). In the present method design, the red dot, main stimulus was immobile and other cues location were shifting acting as motion features and eventually creating a blank display between the two visual systems, hence bringing delays in response time. With a standardized procedure, a randomization in attributing participants to their task, contouring variables Kept to a strict Mullen, tens true-experiment gives strong evidence that reaction time increases with visual distraction. Although, the small size of the computer used during the experiment and the nature of the stimulus being simple, in AD and right in front of the participant (using direct vision only) can be seen as disconnected from the real world. Its ecological validity can be questioned since in the everyday life, people have to deal with AD, complex and multiple stimulus and this experiment doesnt show how peoples reaction time is influenced in a real world situation. Also, participants had to repeat the test seven times (including the trial) which could have caused fatigue and consequently delays in reaction time. It isnt known to what extend this parameter was involved in the experiment results. The results found that a visual stimulus can make difference in milliseconds in someones reaction time, and for drivers, this is not negligible. Mummer et al. showed that visual distraction impairs drivers ability in being critical and in dealing with sudden events. Saber et al. (2012) stated that visual stimuli, especially in-car technology, resulted in high workload in the brain and more off-road glances. Hence, it should not be underestimated and included in road safety measures. Visual advertising such as hoots, posters, etc. Installed near roads can distract drivers and make them loose attention especially on motorways where the high speed requires drivers to have an optimized reaction time. Road assignation should also be kept to minimal designs with clear and identifiable colors not to delay drivers reaction time. In general, the environment nearby the road should be kept as clean and simple as possible to avoid any visual distraction. Further research should investigate the potential different levels of visual distraction and see if more complex and/or other types of stimuli provoke different and longer exaction times. Forms and shapes were used in this experiment, but exploring the humans reaction time when presented faces cues for instance could bring new learning. It seems that after practicing, visual distraction are start not being seen as distraction (And, 2002). Previous research also showed that experienced drivers had a faster reaction time than learners because they were using more often side mirrors (Constantinople, Chapman, Crandall, 2010).

Megapnosaurus (Syntarsus) - Facts and Figures

Megapnosaurus (Syntarsus) - Facts and Figures Name: Megapnosaurus (Greek for big dead lizard); pronounced meh-GAP-no-SORE-us; also known as Syntarsus; possibly synonymous with Coelophysis Habitat: Woodlands of Africa and North America Historical Period: Early Jurassic (200-180 million years ago) Size and Weight: About six feet long and 75 pounds Diet: Meat Distinguishing Characteristics: Large size; bipedal posture; narrow snout; strong hands with long fingers About Megapnosaurus (Syntarsus) By the standards of the early Jurassic period, about 190 million years ago, the meat-eating dinosaur Megapnosaurus was hugethis early theropod may have weighed as much as 75 pounds, hence its unusual name, Greek for big dead lizard. (By the way, if Megapnosaurus sounds a bit unfamiliar, thats because this dinosaur used to be known as Syntarsusa name that turned out to have already been assigned to a genus of insect.) Complicating matters further, many paleontologists believe that Megapnosaurus was actually a large species (C. rhodesiensis) of the much better-known dinosaur Coelophysis, the skeletons of which have been unearthed by the thousands in the American southwest. Assuming that it does deserve its own genus, there were two distinct variants of Megapnosaurus. One lived in South Africa, and was discovered when researchers stumbled on a bed of 30 tangled skeletons (the pack had apparently been drowned in a flash flood, and may or may not have been on a hunting expedition). The North American version sported small crests on its head, a hint that it may have been closely related to another smallish theropod of the late Jurassic period, Dilophosaurus. The size and structure of its eyes indicates that Megapnosaurus (aka Syntarsus, aka Coelophysis) hunted at night, and a study of the growth rings in its bones reveals that this dinosaur had an average life span of about seven years.

Cancer Nanotechnology Essays

Cancer Nanotechnology Essays Cancer Nanotechnology Essay Cancer Nanotechnology Essay Going small for big Advances Abstract At present there are wide varieties of Technologies, which are vastly being used to analyze biological cells to diagnose diseases and develop methodologies to cure diseases. One such technology is Nanotechnology’. A nanometer is a billionth of a meter. Its difficult to imagine anything so small, but think of something only 1/80,000 the width of a human hair. Ten hydrogen atoms could be laid side-by-side in a single nanometer. Nanotechnology is the creation of useful materials, devices, and systems through the manipulation of matter on this miniscule scale.The emerging field of nanotechnology involves scientists from many different disciplines, including physicists, chemists, engineers, and biologists. Nanotechnology will change the very foundations of cancer diagnosis, treatment, and prevention. Nanoscale devices used for treatment of Cancer are based on the constant study of cancer cells and nanotechnology. Nanoscale devices which are smaller than 50 nanometers can easily enter most cells, while those smaller than 20 nanometers can move out of blood vessels as they circulate through the body.Because of their small size, nanoscale devices can readily interact with biomolecules on both the surface of cells and inside of cells. By gaining access to so many areas of the body, they have the potential to detect disease and deliver treatment in ways unimagined before now. Since biological processes that lead to cancer occur at the nanoscale at and inside cells, nanotechnology offers a wealth of tools with new and innovative ways to diagnose and treat cancer. In our paper we design a device that contains sensors, transceivers, motors and a processor, which are made up of biodegradable compound.No more destruction of healthy cells due to harmful toxins and radiations generated through chemotherapy and radiation therapy. Introduction The paper deals with the eradication of cancer cells by providing an efficient method of destroying and curing the cancer so that healthy cells are not affected in any manner. This technology also focuses on a main idea that the patient is not affected by cancer again. The purpose of using the RF signal is to save normal cells. Nanotechnology in this contextNanotechnology refers to the interactions of cellular and molecular components and engineered materials at the most elemental level of biology. This paper emphasizes on the effective utilization of Nanotechnology in the treatment of cancer. What is cancer? Cancer cells are different from healthy cells because they divide more rapidly than healthy cells. In addition, when cells divide at an accelerated rate, they form a mass of tissue called a tumor. These cancerous cells that come in excess amounts cause many problems to the bodies of patients.In general, the most common methods used for the cancer treatment are u Chemotherapy, a treatment with powerful medicines u Radiation therapy, a treatment given through external high-energy rays. Problem Both the treatments mentioned above are harmful. Healthy cells are destroyed in the process. As a result, this leaves the patient very weak, causing him not able to recover quickly to medical treatments. It has been proved that any individual who had cancer can survive on deadly chemotherapy up to a maximum of five years and after that it’s anybody’s guess.Proposed solution The nanodevices can be programmed to destroy affected cells and kill only them, thus ending the problem of destroying any normally functioning cells which are essential to one’s well-being. Thus the treatment-using nanotechnology will make the affected man perfectly normal. Noninvasive access to the interior of a living cell affords the opportunity for unprecedented gains on both clinical and basic research frontiers. Nanotechnology and diagnosticsNanodevices can provide rapid and sensitive detection of cancer-related molecules by enabling scientists to detect molecular changes even when they occur only in a small percentage of cells. Cantilevers Nanoscale cantilevers microscopic, flexible beams resembling a row of diving boards are built using semiconductor lithographic techniques. These can be coated with molecules capable of binding specific substrates-DNA complementary to a specific gene sequence, for example. Such micron-sized devices, comprising many nanometer-sized cantilevers, can detect single molecules of DNA or protein.As a cancer cell secretes its molecular products, the antibodies coated on the cantilever fingers selectively bind to these secreted proteins. These antibodies have been designed to pick up one or more different, specific molecular expressions from a cancer cell. The physical properties of the cantilevers change as a result of the binding event. This change in real time can provide not only information about the presence and the absence but also the concentration of different molecular expressions. Nanoscale cantilevers, thus can provide rapid and sensitive detection of cancer-related molecules.Nanotechnology and Cancer therapy Nanoscale devices have the potential to radically change cancer therapy for the better and to dramatically increase the number of highly effective therapeutic agents. Nanoscale constructs, for example, should serve as customizable, targeted drug delivery vehicles capable of ferrying large doses of chemotherapeutic agents or therapeutic genes into malignant cells while sparing healthy cells, which would greatly reduce or eliminate the often unpalatable side effects that accompany many current cancer therapies. NanoparticlesNanoscale devices have the potential to radically change cancer therapy for the better and to dramatically increase the number of highly effective therapeutic agents. In this example, nanoparticles are targeted to cancer cells for use in the molecular imaging of a malignant lesion. Large numbers of nanoparticles are safely injected into the body and preferentially bind to the cancer cell, defining the anatomical contour of the lesion and making it visible. These nanoparticles give us the ability to see cells and molecules that we otherwise cannot detect through conventional imaging.The ability to pick up what happens in the cell to monitor therapeutic intervention and to see when a cancer cell is mortally wounded or is actually activated is critical to the successful diagnosis and treatment of the disease. Nanoparticulate technology can prove to be very useful in cancer therapy allowing for effective and targeted drug delivery by overcoming the many biological, biophysical and biomedical barriers that the body stages against a standard intervention such as the administration of drugs or contrast agents. Working procedure:The initial step of identifying the cancer and the location can be done by scanning. Once the location has been identified through scanning, the task is to position the nanodevice to the exact location. We focus on the positioning of the nanodevice into the required location by itself. The nanodevice is allowed to be placed into any part of the body (or) the nano device is injected through the blood vessel. The positioning is done with the help of mathematical calculations. External Control signals could be used to avoid mishap or any other errors. The nanodevice is loaded with a microchip.The device is also provided with the compounds concealed so that it is initiated externally through a computer. The nano device contains sensors, motor, gene reader, processor, transceiver, camera and power supply. The location of the cancer cells is given as coordinates in a 3-dimensional point of view. This point is considered as the reference and referred as (0, 0, 0). Positioning The nanodevice performs an internal calculation based on the difference between its current position and the reference. Mathematical computations involve such that only one axis is compared between the nano device and the reference at a time.The motor fan is placed in a particular direction for a particular reference comparison. After one of the axis is completed and comparison is done, then the next axis is being compared followed by the third. Thus the three co-ordinate comparison of the nano-device results in any 3- Dimensional orientation of the nano-device and results in exact positioning. Navigation The output of the mathematical operation is given to a driver circuit (motor). The driver helps the device to navigate through the blood with precision in direction and with the required speed.The device thus should sample its new position with the reference at a sampling rate. The sampling rate is made such that their value is less than the velocity of blood flow. The cancer killer could thus determine that it was located in (say) the big toe. If the objective were to kill a colon cancer, the cancer killer in the big toe would move to the colon and destroy the cancer cells. Very precise control over location of the cancer killers activities could thus be achieved. The cancer killer could readily be reprogrammed to attack different targets using acoustic signals while it was in the body.Algorithm for navigation: Ste11: Marking the co-ordinates. Step2: Initialize the start command. Step3: Feed the axis. Step4: Send command to emit ultrasound. Step5: Wait for T seconds. Step6: If there is no signal reflected back (or) if the reflected signal is less than the threshold value, then activates the stepper motor to rotate through a certain distance. (Note: the distance is proportional to one axis) Step7: Subtract the axis value by one. Step8: Continue from step4 to step7 for both co-ordinates. Step9: If the signal reflected back is greater than the threshold value then the motor is de-activated.Step10: The motor (perpendicular to motor1) is activated. The motor2 moves through one step thus making the motor1 to change the axis. Step11: The motor1 is allowed to travel until next change is required. Step12: Once the nanodevice reaches the required spot, the motor is deactivated through external command. Step13: Receives the RF radiation for T seconds that has been already calculated depending upon the intensity of tumor Imaging With the available technology, a camera is inserted which helps us to monitor the internal process.Whenever multiple directions are there in the blood vessel, the device is made to stop through the external control signal and another signal is given to activate in the right direction. Current clinical ultrasound scanners form images by transmitting pulses of ultrasonic energy along various beam lines in a scanning plane and detecting and displaying the subsequent echo signals. Our imaging is based on the absolute scattering properties and in the frequency dependence of scattering in tissues, which will help to differentiate between normal and abnormal cells. IdentificationThe nano device identifies the cancer cells using a gene reader. A gene reader is a sensor which contains ten to fifty DNA probes or samples of cancer cells that are complementary. The DNA detection system generates an electronic signal whenever a DNA match occurs or when a virus causing cancer is present. Whenever we get a signal indicating the presence of cancer cells we go for further process. Once the device has been originally located, the next step is the destruction of the cancer cells. Destruction: We can remotely control the behavior of DNA using RF energy.An electronic interface to the biomolecule (DNA) can be created. RF magnetic field should be inductively coupled to nanocrystal antenna linked covalently to a DNA molecule. The inductive coupling results to the increase in the local temperature of the bound DNA, allowing the change of state to take place, while leaving molecules surrounding the DNA relatively unaffected. The switching is fully reversible, as dissolved molecules dissipate the heat in less time duration. Thus RF signal generated outside the body can destroy the affected DNA. Rf heatingThe treatment tip contains the essential technology components that transform RF to a volumetric tissue heating source. The heat delivery surface transmits RF energy to the cells. Tumors that have little or no oxygen content (i. e. hypoxia) also have increased resistance to radiofrequency radiation. Thus, due to high resistance to radio frequency radiation the affected cells get heated and hence destroyed. The RF carrier frequency is in the biomedical range (174 216MHz). A pair of RF pulses is transmitted at a frequency of about 1-2Hz. How nano device escapes from immune system?Generally our immune system attacks all the foreign particles entering any part of our body. The problem has been that such nano particles are similar in size to viruses and bacteria, and the body has developed very efficient mechanisms to deal with these invaders. It is known that bacteria with hydrophilic surfaces can avoid being destroyed by immune system and remain circulating in the body for longer periods. To emulate this effect, our nano device can be coated with a polymer such as polyethylene glycol (PEG), Which is proved after the research. Conclusion:As per our aim we have proposed the usage of nanotechnology and the RF signal for the destruction of cancer cells. This method doesn’t affect the healthy cells such that the cancer affected person is healthy after the treatment. This treatment doesn’t involve critical operations. This treatment will not take longer time as in any other treatments. Surely one day or the other cancer treated patient will be affected again treatment. This can be very well used for other dangerous diseases. Name : R. Ramesh College : k. c. g college of technology Email address : [emailprotected] com
