Adherence Reaction Paper - Essay Example On Mondays and Fridays, I also include my vitamin B-6 tablet, which I am required to take twice per week. This concludes my morning routine, but not the medication regimen for the day. At night, I take another calcium carbonate and a capsule and a half of Zoloft, which, as it warns, does make me drowsy and helps me get to sleep at night. There are several things that help me adhere to this regimen. I have a pill caddy that I refill every week and carry with me everywhere I go. The rattle of it reminds me to check if I have taken my medication yet while the proper dosage of each pill for each day is already there for me. This is especially helpful for the odd B-6 pill that I am only supposed to take twice per week and is thus easy to forget. During the week, when I have a more regular schedule thanks to my volunteer job at the library, it is relatively easy to keep myself on this regimen. I have to get up at a specific time in the morning anyway in order to get ready for my ‘job’ and the evenings remain relatively quiet so that I can get enough sleep for tomorrow’s work. On the weekends, though, it becomes more difficult because I want to sleep in later, but still get hungry at the same time and I want to stay up later, but the Zoloft continues to make me sleepy. I am motivated to continue taking the medicine, though, out of fear of having a heart attack or simply not be capable of eating comfortably if that horrible heartburn feeling returns. At the same time, there are many things that make me wish I could just scrap the regimen altogether. When I am not volunteering, it is nice to lose all track of scheduling constraints. I like to sleep in late and take my time on various things. On these days, I am usually ravenously hungry when I wake up but have to put this on hold if I want my medications to be effective. This is

Issues in the Construction of the Scottish Parliament

Issues in the Construction of the Scottish Parliament Introduction This report intends to answer how a national iconic project turned into â€Å"a hugely expensive and politically embarrassing fiasco?† (Fortescue, 2004) by analyzing the reasons that led to delay, cost overrun and quality issue in construction of new Scottish Parliament Building. This report has utilized the researches available on the internet, auditors report and other articles available from varied sources. This report will start by introduction to the background of Scottish Parliament project and will continue by discussing the reason for delays and cost increases, role of the project management and at the end concluding the lessons learned from this project. The reason for selection of this project is that the Scottish Parliament building was estimated to be completed in  £40m but finished at over  £400m which is an interesting parameter to study (BBC, 2004). Background to the Scottish Parliament Project: After the referendum in 1997, Scottish parliament was established as a devolved legislature by Scotland Act 1998. Thereafter, Donald Dewar, Secretary of Scotland state adjudicated to have a purpose built facility to accommodate the Parliament in the Edinburgh city. After having a chaotic journey to completion, Scottish parliament Complex was inaugurated on 9 Oct 2004 by Queen Elizabeth II. Remarkable features of the complex consist of leaf-shaped buildings, flipped over boat shaped roof, a grass-roofed division meeting into adjacent parkland and gabion walls made from the stones. All over the building there are various repeated motifs. Scottish parliament is a complex building comprising of new and old buildings such as Dewar room, Canon gate building, Debating chamber, Garden lobby, MSP building, Media tower, Main hall, Tower building, and Queensberry house. All of these buildings were renovated or constructed as per Architects vision. High end materials like Granite, Cattiness Ston e, Oak Timber, Sycamore Timber, Steel Glass and Marble was used in the construction. Detailed environment and sustainability study was carried out which confirmed that propose built complex is environment friendly (Fraser, 2004). Brief summary of the Project: Road to Holyrood Site Selection: To begin with, Edinburgh City Council provided a long list of 27 sites in Edinburgh. In September 1997 officials short listed three leading options: two new build options, either at Leith or Haymarket, or adapting and developing the existing St Andrews House building (old Royal high school). At this stage, an engineer Jones Lang Wootton was engaged by the Scottish office to viably evaluate the acquisition costs of the shortlisted sites. Measurements of environmental issue and traffic issue were also considered at this point. Haymarket was never considered as preferred option and officials sensed real hostility in Edinburgh to house the Parliament anywhere except centrally thus reducing the chances of Leith (Auditor General, 2000). The Holyrood site was not considered at this stage as it was occupied by Scottish and Newcastle brewery and was anticipated that it would not be completed within the required deadline. However, an accidental meeting of a civil servant on train with an official of Newcastle and subsequent negotiations resulted in the company demonstrating that they would evacuate the site in early 1999. As a consequence, on 8th December Holyrood was short-listed, and design and cost viability studies undertaken. Davis, Langdon and Everest (DLE) , Cost Consultants were commissioned to provide initial cost estimate for proposed sites and the Holyrood site was selected in early 1998 from the shortlist based on the following cost estimate (Auditor General,2000).: Design Selection: Once, the location was finalized the Scottish Office announced an international competition to acquire a designer for a new-fangled building to accommodate the parliament through a competitive selection procedure. The competition was suitably setup with a press release on 26 January 1998. The final design teams named on 7th May 1998 providing the project cost as being in the range of  £50 million excluding VAT (Fraser, 2004). Under the chairmanship of Dewar, a design committee was allotted to choose from a shortlist of designer. Conceptual designs were cost and displayed for public to view and provide their opinion. Feedback from the public depicted that the Catalan architect Enric Miralles designs were one of the most popular. The design team considered public opinion on the designs, and on 6 July 1998 the Enric Miralles‘s design was selected, with work being awarded to a Spanish Scottish design company namely EMBT/RMJM (Scotland) Ltd, exclusively created for the project. Construction management system of procurement was adopted and BLL was appointed as construction manager. In June 1999, construction commenced, by demolishing the Scottish and Newcastle brewery and opening the foundation work (The royal society of Edinburg, 2001). Journey of Estimate: The construction of the Scottish Parliament Complex generated controversy in several aspects. Spiraling costs and the use of public capital to fund the project rendered most controversy. By early 2004, the project was estimated to be  £430m, some ten times higher. In my opinion it is not fair to compare final figure with initial figure of  £10m as it was never an estimated price but an indicative one (Fraser, 2004). Time delay and cost overrun From the beginning, the complex and its construction have been controversial. For instance, Auditor General of Scotland expressed â€Å"in the recent history of Scotland there has not been public building project as complex or as difficult to deliver as the Holyrood Project† (Prasser, S., n.d.). Almost all aspect such as location, design, architect, construction management company, project manager all have been criticized by different factions namely, politician, media and general public. Due to complexity of the project, it is very difficult to single out one reason for delay and cost overrun but infect it was compound and interaction of many factors that resulted in delay and cost overrun (Fraser, 2004). Location: Selection of Holyrood to be the seat of parliament has contributed to delay and cost overrun. Holyrood was not an easy area to work due to the approach and being located in populated area. The selection of Holyrood added  £4.5m to the project being the cost for site acquisition and clearing. As the table1.1 (Fraser, 2004) shows, according to the costing done by DLE Holyrood was not economically attractive. Design and Design Development Factor: Main cause of the delay to the project was from Sept2000 due to the production of detailed design variations and the late supply of information during the construction process (Auditor General, 2004). Construction started in June1999 but Stage D design was approved after a year. Everyone anticipated that this will put an end too uncertainly and provide some sort of anchorage for the project but it did not happen. The project was densely populated, unusual and complex and was pitted against tight deadline. In some cases, trade contractors were responsible for part design but both the architects and some trade contractors failed to deliver some critical elements on time. Design development process added another  £80m to the cost of project. It is a process of bringing approved design to detailed design. This process runs parallel to Tendering and award of work packages and subsequent work on site. From 2000 onward, client didnt change its requirements significantly but the cost of br inging envisioned design to reality escalated (Black, 2004). Increase in area: after several revisions and new requirement were incorporated, total area reached from 16000.00 m2 to 31,000.00 m2 resulting in an increase of 47% and consequently effecting schedule and cost of the project. Building users brief prepared by the authorities substantially underestimated the requirements which resulted in various revisions and thus increase in area. For instance, Mr. Stewart said that the original estimate was â€Å"absolutely, too optimistic for a public building of this nature† (Fraser, 2004). The experience and expertise in construction management was not fully developed and was not present in the early stages of development. Procurement vehicle: In 1998, Civil servants opted for fast track method known as construction management form of procurement to build the parliament complex (Fraser, 2004). It works by fragmenting complete job into several small packages that are awarded, monitored and designed independently of one another. Its advantage is that the overall design doesnt have to be complete at the start of building works. In this form of contract, risk stays with the client, which is responsible for management of each individual work package-in this case around 60. However, after keeping in mind importance and urgency of the project, construction management procurement was the only viable option available. For instance, Harry Thorburn articulated, â€Å"The reality is that construction management was the only contract option for a client wanting to make an early start on a project that was still at the design concept stage† (Fortescue, S. 2004). Communication and coordination was another issue which added to the foes of already troubled project. Fraser (2004) reports that there was a lack of communication, coordination and understanding between stakeholders, for example, resolution of many design issues was delayed due to misunderstanding and lack of communication between RMJM EMBT. Landscaping is although minor part of overall figure, still it reflects failure of system. Cost of landscaping amounting to  £ 14 m came to the surface and was added when the project was well underway during autumn 2001 (Fraser, 2004). Schedule: Time-table for completion by project management was very demanding and idealistic rather than realistic. Construction manger consistently tried to achieve the set target but failed. According to Auditor Generals report (2004), schedule set in Sept 2000 for completion by December 2002 was probably unachievable. Proper EU guidelines and procedures were not followed for appointment of Bovis Lend and Lease as construction manager. BLL was not the lowest, yet they were awarded. BLLs contract was supposed to be converted to Lump sum after finalization of cost plan but was not done. Conversion of fees would have provided a powerful incentive to Bovis to apply maximum rigor in relation to cost control. No system was devised and implemented neither for performance measurement nor for cost reporting, analysis and financial control. Queensberry House proved to be the most costly item, in terms of cost per square meter (Fraser, 2004). However, Queensberrys cost was comparatively minor in context of the full cost of the Project at completion. Golden triangle of quality time and cost was ignored and quality was preferred against time and cost, time was preferred against cost. The undue importance given to time and quality resulted in escalated cost. Security issue and 9/11 factor also played an important role in delay and spiraling cost of the project. Fraser in his inquiry agrees that security bill amounted to  £29.11. Design of anti-blast measures causes a sum of  £17.54m and delay associated with blast causes additional sum of  £11.57m. Another major factor to be recognized was constructing a very complex, unusual building, visionary architecture was difficult to bring to reality. The Debating chamber roof, for example, was an extremely challenging task both for designers and builders (Fraser, 2004). Proper risk analysis and cost management studies were not done. At the early stage of decision making, no independent professional project management company was involved to advise the client. Role of Project Management Role of Project management is to deliver the project on time, within budget and with acceptable quality (Fraser, 2004). In this case, Project management provided an exceptional complex of high quality but failed miserable in context to cost and time. Black (2004) criticized performance of the project management or officials responsible for delivering the project. Decision making process and control over project was not clearly recognized along with lack of leadership. Normally project director is responsible for leadership and control, client delegates the authority to project director to render the project. Here, project director should have had clear responsibility in making decisions on balancing time, cost and quality/performance of the project. Auditor General (2004) affirmed that the client (the Parliament) did not clearly establish leadership and control of project. Leading parties could not agree on cost plan which was a missing link in effective project management, a draft plan was made in late 2000, that was an indicator of the costs instead of available estimate of the cost. Under construction management, design was vague and deficient initially, therefore the risks remained with the client (Fig 1.1). Project management selected a high risk route but failed to manage it properly. Risk accounting was insufficient in early stages and there was no quantified allowance for risk facing the project. Initially project management did introduce a process for quantifying risk and conducted some reviews but the general approach was to accept the cost increase and increase in the forecast as risk materialized. No system or forceful action was adopted to reduce the increase in cost (Fraser, 2004). Project management did not fully implement cost reporting and financial controls. Regular reporting of the total estimated costs of the project only started in July 2003(Black, 2004). Earlier financial reporting was neither comprehensive nor systematic. Once, the overall budget constraint of  £195m was removed by Parliament in June 2001, management did not establish an alternative budget which gave them liberty to achieve high quality and tight deadlines without due considerations of cost implications (Black, 2004; Fraser 2004). Conclusion Project management plays an important role in the success of mega and prestigious projects. Construction of Scottish parliament has put a negative mark on the role of project management. Delay and cost overrun of the project cannot be attributed to the failure of project management only, Fraser (2004) in his inquiry stated that it was the result of systematic failure and it is difficult to single out one villain. Also, there were several mistakes but the biggest one was involved in Procurement system. They were interconnected, increased exponentially, and had a rippling effect which was visible all throughout the period of construction. Despite of all the problems, Scotland has got an architectural gem; its an iconic building representing the land. In few years, the people of Scotland will be as proud of it as the people of Sydney are of Opera House, which was also an example of project failure when it was built (Australian Government Department, 2006; Mosaic Projects, n.d.). The entire project should have agreed project budget and proper set of performance indicators. Proper benchmarking should be done to measure the performance. If, competition is commissioned for selection of design, proper evaluation of pre qualification must be done and compatibility of working cultures should be considered. While selecting the design, attention should be paid to cost and execution problems that may arise due to complexity of design. Procurement route must always be chosen with care coupled with comprehensive evaluation. Construction management procurement route should be used rarely for public projects. Before construction starts adequate time should be available for the planning stage. As Fraser (2004) reports that investing time initially, to develop complete definitions reduces the chance of changes later. Good planning will involve (a) right sequence of construction to avoid delays and extra costs, (b) risk management (c) using value management to evaluate the role of each element of the construction processes (Black, 2004) (d) Selection of proper planning system â€Å"There must always be sufficient time for procurement to allow the clients requirements to be adequately defined so that it may obtain fixed and firm prices for the work in a competition† (Black, 2004). In all projects, performance payment incentives system should be initiated for contractors to perform against targets for quality, time and cost. Clearly defined duties and single point of leadership with explicit authority and responsibility should be ensured. Strong system of reporting and transparent channels of communication must be devised. It is essential that full contracts, guarantees and bond should be secured to prevent the risk. Early involvement of contractors in design phase might help in solving the problems later on. Concurrent engineering should be carried out to avoid complications during execution. Safety measures needs to be a considered as an integral part. In this particular case, no one would have anticipated the impact of 9/11. So it is better to have some contingency plan in place to tackle unforeseen events.

Happiness in Brave New World :: Brave New World Essays

Happiness in Brave New World Huxley implies that by abolishing nastiness and mental pain, the brave new worlders have got rid of the most profound and sublime experiences that life can offer as well. Most notably, they have sacrificed a mysterious deeper happiness which is implied, but not stated, to be pharmacologically inaccessible to the utopians. The metaphysical basis of this presumption is obscure. There are hints, too, that some of the utopians may feel an ill-defined sense of dissatisfaction, an intermittent sense that their lives are meaningless. It is implied, further, that if we are to find true fulfilment and meaning in our own lives, then we must be able to contrast the good parts of life with the bad parts, to feel both joy and despair. As rationalisations go, it's a good one. But it's still wrong-headed. If pressed, we must concede that the victims of chronic depression or pain today don't need interludes of happiness or anaesthesia to know they are suffering horribly. Moreover, if the mere relativity of pain and pleasure were true, then one might imagine that pseudo-memories in the form of neurochemical artefacts imbued with the texture of "pastness" would do the job of contrast just as well as raw nastiness. The neurochemical signatures of deja vu and jamais vu provide us with clues on how the re-engineering could be done. But this sort of stratagem isn't on Huxley's agenda. The clear implication of Brave New World is that any kind of drug-delivered happiness is "false" or inauthentic. In similar fashion, all forms of human genetic engineering and overt behavioural conditioning are to be tarred with the same brush. Conversely, the natural happiness of the handsome, blond-haired, blue-eyed Savage on the Reservation is portrayed as more real a nd authentic, albeit transient and sometimes interspersed with sorrow. The contrast between true and false happiness, however, is itself problematic. Even if the notion is both intelligible and potentially referential, it's not clear that "natural", selfish-DNA-sculpted minds offer a more authentic consciousness than precision-engineered euphoria. Highly selective and site-specific designer drugs [and, ultimately, genetic engineering] won't make things seem weird or alien. On the contrary, they can deliver a greater sense of realism, verisimilitude and emotional depth to raw states of biochemical bliss than today's parochial conception of Real Life.

Time dispersion parameters

When a signal is transmitted, this signal can endure a deformation caused by contemplations and scattered extension waies in the wireless channel, and these phenomenons cause that an indistinguishable signal arrives at different times at its finish. These different times are due that to the signal arrives via multiple waies and in different incident angles. The clip difference between the arrival minute of the first multipath constituent and the last 1 is called hold spread. In order to compare different multipath channels and to develop some general design guidelines for wireless systems, some parametric quantities are used to quantify the multipath channel. Some of these multipath parametric quantities are the average extra hold, rms delay spread, and maximal extra hold, and can be determined from a power hold profile. However, the mean extra hold and the rms delay spread are often used to quantify the clip diffusing belongingss of broad set multipath channels.Mean Excess DelayThe Mean Excess Delay is the first minute of the power hold profile ( PDP ) and is defined byRMS Delay SpreadThe root-mean-square ( RMS ) hold spread is likely the most of import individual step for the hold clip extent of a multipath wireless channel. This parametric quantity calculates the standard divergence value of the hold of contemplations, weighted relative to the energy in the reflected moving ridges. This parametric quantity can be considered like the square root of the 2nd cardinal minute of the power hold profile and is defined by We must take into consideration that these holds are measured comparative to the first noticeable signal arriving at the receiving system at = 0, and their equations do non trust on the absolute power degree of P ( ) , but merely the comparative amplitudes of the multipath constituents within P ( ) .Maximum Excess Delay ( X dubnium )The maximal extra hold ( X dubnium ) of the power hold profile is defined as the clip hold value after which the multipath energy falls to X dubnium below the maximal multipath energy ( non necesarily belonging to the first arriving constituent ) . It is besides called extra hold spread, but in all instances must be specified with a threshold that relates the multipath noise floor to the maximal standard multipath constituent. The values of these clip scattering parametric quantities besides depend on the noise threshold used to treat P ( ) , and if this noise is set excessively low, so the noise will be processed as multipath and therefore doing the parametric quantities to be higher.EnvironmentCoherence BandwidthCoherence bandwidth is a statistical step of the scope of frequences over which the channel can be considered â€Å" level † . If we define Coherence Bandwidth ( BC ) as the scope of frequences over which the frequence correlativity is above 0.9, so If we define Coherence Bandwidth as the scope of frequences over which the frequence correlativity is above 0.5, so The coherency bandwidth of the channel gives a good indicant about the frequence fluctuations of the channel in relation to the bandwidth of the familial signal. We can hold two different instances, depending on this bandwidth. If a signal with a bandwidth larger than Bc is transmitted through the channel, it will be capable to frequency selective deformation. The channel will be, in this instance, referred to as a frequence selective attenuation channel. However, if the signal transmitted has a bandwidth well less than Bc, it will see amplitude fading merely with no deformation since the channel features will be the same all over the spectrum of the signal. In this instance the channel is referred to as a frequence non-selective ( level ) melting channel.

INFORMATIVE SPEECH TOPICS The main questions for picking out good informative speech topics are: What are their wishes, tastes, interests and needs? What is their level of education and knowledge about the topic? Is their a common ground between you and your audience? Can you surprise them with new information? Can you excite their interest by expanding on what your listeners already know? Are you having trouble coming up with speech topics? This list of informative speech topics is only meant to stimulate your thinking. Of course many of these subjects are too broad and ought to be narrowed.
