Fire Safety Strategies For Sainsburys Warehouse Environmental Sciences Essay

Fire Safety Strategies For Sainsburys Warehouse Environmental Sciences Essay The purpose of this Outline Fire Strategy Report is to facilitate preliminary discussions with the Approving Authorities and to outline the approach that will be taken to show compliance with Part B (Fire Safety) of Schedule 1 to the Building Regulations (2000 2006). This report will provide a brief summary on all the aspects of fire safety which correlate with the corresponding Building Regulations. However, it will focus primarily on issues pertaining to the Fire Detection (AFD) and Alarm system and linking factors, such as evacuation times and fire growth. Since the 1960s there has been a rapid increase in the construction of large single storey storage warehouse facilities in the United Kingdom (UK). One of the most notable of these was the 40,000m2 unsprinklered military storage facility constructed by the Ministry of Defence (MOD) at Donnington. In 1983 this storage facility was completely destroyed by fire despite the presence of an on-site fire service. The fire at Donnington and other unsprinklered warehouses circa 1980 raised concerns in the UK and the United States (US). They present an extremely high risk to firefighters due to size and fire loading, devastating was the incident in November 2007, which was a fire in a vegetable packing plant located in Warwickshire that resulted in the tragic loss of four firefighters. Over the last 2 decades there has been an increase in the use of warehouses as a crucial part within the supply chain, this has been accelerated to deliver a just-in-time delivery system that has demanded more sophisticated processes. Where property protection sprinkler systems are installed with additional enhanced features, significant improvements upon the 80% reliability can be achieved.. 3 Description of the issue to be solved When minimum fire protection measures are provided (i.e. manual fire alarm, 2m floor to ceiling height, etc), ADB suggests maximum travel distances in warehouse accommodation of 25m in a single direction of travel and 45m where two means of escape are provided. The proposed building contains a number of inherent fire safety features such as high ceilings, automatic fire detection, sprinklers and an open plan environment. Such features assist in prolonging the onset of hazardous conditions and increase the chance of a person becoming aware of a fire in the initial stages of its development independent of the alarm being raised by others. Therefore, the basic recommendations set out in ADB are considered to be unduly restrictive fir the proposed building. The 2.5 min notional escape time used in current guides came from the Empire Palace Theatre Fire in 1911, as it was the time taken for the audience to escape, which was measured due to the Orchestra playing God saves the King during t he evacuation. Many other requirements within the prescriptive code developed in the same way with no specific foundation to support them. Figure 4 Methods and schemes To comply with the functional requirements the Secretary of State has approved a series of Approved Documents, which aims to provide practical guidance with respect to the functional requirements of schedule 1 and Regulation 7 of the Building regulations 2000 (SI 2000/2531) for England. The approved document for the above function is Approved Document B (Fire Safety), Volume 2 Buildings other than dwelling houses (ADB); however these functional requirements can be achieved in a number of different ways. This report will focus on B1. 4.1 Approved document B and solution of fire engineering ADB states the following: Fire safety engineering may provide an alternative approach to fire safety. It may be the only realistic way to achieve an acceptable standard of fire safety in some large and intricate buildings and in buildings containing diverse uses. Therefore, where the proposed development does not fully comply with the recommendations of ADB it is intended to incorporate the latest guidance available as part of an alternative fire safety engineering approach. This approach will be base don the recommendations of BS7974 with the overarching aim of achieving the optimum design solution and Building Regulation Approvals. A fire alarm system is designed to detect and raise the alarm in a fire situation for the following purposes: As part of the life safety system (L) For the protection of property (P) For a warehouse the type of system is determined by the current addition of BS5839-1; Fire detection and fire alarm systems for buildings (Code of practice for system design, installation, commissioning and maintenance). Table A.1 of BS5839 Part 1 identifies the appropriate alarm system for the building. Figure If we consider the building as a warehouse the British Standard states that the premises will require the highest standard of property protection a Category P1 system, where automatic fire detectors are installed in all areas of the building. The system is intended to satisfy the requirements of fire insurers as it considers a life safety system not appropriate for the building type as the occupiers are awake and will detect and raise the alarm. This is against the recommended type of system under BS9999 as it states for a fast growing fire with a risk rating of A3 (reduced from A4 due to sprinklers being fitted) requires a L2 alarm system. A mostly unmanned warehouse cannot rely upon a manual response and an automatic fire detection system and/or sprinkler system will be warranted. Historically, the type and extent of fire detection is often dictated by external influences rather than by a measured assessment of the risk and the determination of the most appropriate and effective fo rm of detection. These influences may include the requirements of legislation as enforced by the Fire Authority and Building Control Body, or the requirements of interested parties, such as the Insurer. The alarm will also be capable of operating extinguishing and smoke control systems. Actuation will close fire dampers, open smoke vents and close heating, ventilation and air conditioning systems or switch them over to extraction mode Figure When detecting in large open areas such as atria, warehouses etc, the detection device is likely to be some distance vertically and horizontally from the fire source. Consequently, detection methods should be applicable for such circumstances. There are a number of considerations for protecting such environments, these can include smoke and heat dilution as the fire plume rises towards the fire detectors, the effects of stratification and air currents taking the smoke and gasses away from the detectors. When attempting to assess the probable time to detection, there would need to be a detailed assessment of the environmental conditions affecting fire growth, as the environment is likely to play a major part in the success or failure of the detection system. In this case: tgrowth will be based upon typical fire models for the range of likely combustibles; tmove will be based upon a number of assumptions of how the environment will affect the way the detected products will travel towards the detectors. Parameters to be considered here are the effects of HVAC, the continued entrainment of air as the smoke plume rises (with the possible eddy current created by cooling of the smoke), and the effects of stratification. Warehouses offer particularly unusual challenged to these types of detector since point type smoke detectors are not recommended for use above 10.5m except in unusual circumstances. The reason for this is the well-known phenomenon of smoke stratification, where smoke from any given size fire only produces sufficient thermal buoyancy to raise smoke to a given level (often well away from detectors), rendering conventional smoke detection virtually useless in this application. Beam detectors however negate the problems associated with point detectors. Beam smoke detectors make use of the obscuration property of smoke to detect a fire. They may consist of a combined transmitter and receiver unit with reflective element, or a separate transmitter and receiver unit. They are normally mounted on walls at either side of a monitored area, such that there is a clear line of sight between one unit and the other. Typically, an infrared beam is transmitted along this length. In the event of smoke passing through the beam, the receiver measures the resultant attenuation. The value CL, expressed in dB, is used to identify the reduction in intensity of the light beam, defined by the following equation: I0= received intensity without reduction in intensity I = received intensity after reduction in intensity The main requirements are that: The detectors have sufficient immunity to false alarm conditions such that CL, min is less than 0.5 dB; The variation in response between successive operations should be limited such that the ratio between the maximum value of CL, max recorded and the minimum value CL, min is less than 1.6. Although this data is used in testing detectors, it may also be appropriate in assessing on-site conditions. By contrast, high sensitivity aspirating systems may often have their sampling pipes arranged to sample from multiple heights within the protected area, overcoming this problem. However they are cost prohibitive within this scheme. 5 Analysis and computations 5.1 Assumption To demonstrate the building complies with the functional requirement B1 a fire safety engineering analysis of the performance based design will need to be adopted as recommended in BS7974. Making use of basic physical provisions to ensure life safety, but design evaluation depends upon a time based comparison of the time available for the occupants to escape (Available Safe Escape Time, (ASET)) and the escape time (Required Safe Escape Time, (RSET)). This will allow the design to deviate form the restrictions imposed by the prescribed rules Research on Evacuation Times. Standard fire safety recommendations for means of escape relate to travel time, i.e. the time taken to travel to and through exits to a place of relative safety. However, it is widely acknowledged that the time taken for occupants to start to evacuate can be considerably longer than the time taken to actually move out of the building. An extract of Table C.1 from BS7974-6 is partially replicated in Figure 4. This demonstrates the potential variation in pre-movement times of evacuees which is dependent upon the level of management and fire alarm provision. The management of this building will adopt a proactive fire safety management approach to comply with standard fire safety regulations for the workplace. Figure A1-A2: Automatic fire detection and alarm throughout building A3: Automatic fire detection and alarm only in certain areas, or manual call points only throughout There has been a number of real fire tests carried out on high rack storage arrangements by insurance companies. Tests carried out by Underwriters Laboratories Inc. concluded that fire size is unlikely to exceed 5MW where in-rack sprinklers have been provided. Smaller tests on single racks of clothing would indicate a typical peak heat release rate of 2.5MW for isolated arrangements. BRE 368 would also suggest a peak heat release rate of 2.5MW for sprinklered fires using fast response sprinkler heads. Within this project an assumption of a 5 MW fire is made 5.2 Calculation procedures How occupants respond to a fire will depend initially on the cue they received. The components of occupants evacuation times are recognition time, response time and travel time. Both recognition and response times are known as pre-movement time. The former represents the time taken to appreciate that the alarm is a fire alarm relating to the occupant (as opposed to a security alarm, car alarm etc). During this time occupants will continue with activities as they were prior to the activation of the alarm, e.g. staff members undertaking duties, etc. The latter represents the duration taken by occupants to begin to move towards an escape route, e.g. investigative behaviour shutting down machinery etc. Figure In warehouse buildings occupants are generally familiar with their surroundings and are trained in fire emergency evacuation protocols. In the proposed storage facility and associated offices, occupants should be familiar with the sounding of the fire alarm and as such would commence evacuation reasonably promptly. Where a reasonable standard of fire detection is provided, BS7974-6 recommends that familiar occupants of a building can be expected to take between 1mins and 2mins before they start to evacuate. The characteristics and determination of evacuation behaviour can be simplified in terms of the following broad categories of behaviour; the first is Pre-Movement Behaviour and the second is Travel Behaviour. The recommendations of BS7974-6 have been used to determine the Required Safe Egress time (RSET) for the proposed and code compliant layouts. RSET can be calculated using the following formula: rtrset = rtdet + rtalarm + rtpre + rttravel Where; rtrset = Total time required for escape (secs) rtdet = Time to detection (secs) rtalarm = Time to alarm (secs) rtpre = Pre-movement time (secs) rttravel = Travel time (secs) Travel Time is the time required for the occupants to walk to an exit leading to a place of safety. Walking time may be expressed as a distribution of individual times or as a single time such as an average time required. As stated earlier we will assume the maximum travel distance within the warehouse is 60m with no dead end situations allowing for two directions of escape from all areas due to the number of exits provided from the warehouse. We will take the speed of from Annex D PD7974-6 2004 as 1.4m/s. Distance 60(m) ttrav(walking) = - = = 43(s) Speed of travel 1.4 m S 6 Comparison of results with acceptance criteria 6.1 Summary of the results of this case study To meet with code recommendations a Type M manual fire alarm system would be necessary in a standard warehouse building. However, the provision of an automatic fire detection and alarm system is an integral part of the overall fire safety package from a fire engineering perspective. 6.2 Result The building will be provided with an automatic fire alarm and detection system meeting the recommendations of BS 5839-1 Category L2. The system will consist of beam detectors within the warehouse area. Manual call points will be provided at each storey exit and throughout the premises to give warning to the occupants in case of an event other than fire, a voice alarm system will also be installed in accordance with the recommendations of BS 5839-8. The sound level of the alarm system should generally be at least: 60dB (A) in open plan areas>60m2, e.g. offices (excluding a 500mm perimeter boundary) 60dB (A) in staircases and rooms less than 60m2 5dB (A) above the ambient noise level. Table B.1 Typical occupational noise levels (Lp) Figure 7 Conclusions 7.1 Fire protection requirements It is proposed to provide a high standard of automatic fire detection and alarm system throughout the warehousing compartment. A manual system will cover the office area of the premises. The standard of detection and alarm in the building will affect the general time to warning for occupants and provide an enhanced level of fire safety through early warning and shorter evacuation times. Activation of the sprinkler system will also lead to the fire alarm sounding throughout the building. To ensure a conservative estimation of fire alarm activation our analysis has been based on an anticipated sprinkler system activation time within 2 minutes. Many code compliant warehouse facilities with code compliant travel distances only require manual fire detection to meet with code recommendations. Therefore the time to detection would depend on the time taken for occupants in the room of fire origin to raise the alarm. However, should the room of fire origin be unoccupied then the time to alarm for people who may be in rooms remote from the fire would depend on them or other occupants becoming aware of cues of the fire scenario, e.g. sounds of burning material, smell of smoke or seeing smoke through a vision panel. Although BS7974-6 recommends a time to detection of at least 15 minutes for such scenarios, a reasonable worst case for a typical code compliant open plan warehouse could be 3 5 minutes. The fire alarm and detection system will be an addressable analogue system. Multi-state detectors will be capable of giving normal, fire and alternate signals dependent upon the required sensitivity. The control panel will be sited in a low fire risk area (office). It shall have suitable ambient light and sound levels for both staff and FRS use. The fully addressable system will give floor/zone and the specific address of the signals location. There will be 100 second fault monitoring. It will be provided with staff alarm, as well as test, silence and reset buttons. Plan of warehouse Figure

charhf Changes in Huck Finns Character :: Adventures Huckleberry Huck Finn Essays

Huckleberry Finn – The Changes of His Character Throughout the Novel The Adventures of Huckleberry Finn, by Mark Twain, is a novel about a young man's search for identity. Huckleberry Finn goes through some changes and learns some life lessons throughout his journey. Huck changes from being just an immature boy at the beginning of the novel to being a more mature man who looks at things in a different perspective now. In the beginning of the novel, Huck tends to have an immature side to him. There are some things in the beginning that show that Huck still has a very childish side to him. "They get down on one thing when they don't know nothing about it." (Twain 2) This is showing the ignorance and stubbornness that all children experience throughout life. He thinks as if everything he does is right and everyone else is wrong. "That all comes of my being such a fool as to not remember that wherever you leave a dead snake its mate always comes there and curls around it." (Twain 40) This goes one step further. This shows Huck's Immaturity and Stupidity gone one step too far when he puts the snake in Jim's bed and he ends up getting bit by it. If Huck was more mature and less childish he wouldn't have been playing this so called joke on Jim. Huck learns that jokes have a limit to them at times and need to be thought out more clearly. When the middle of the novel comes around Huck begins to distinguish what is right and wrong in life and begins to mature and do the right thing. He shows this when he chooses not to partake in the scam that the King and the Duke are playing on the Wilks family. Instead he takes the money back from the King and Duke to hide it because he believes it is only fair to the family. "I'm letting him rob her of her money...I feel so ornery and low...I got to steal that money somehow; and I got to steal it some way that they wont suspicion I done it" (Twain 133) This shows that Huck is starting to see the line between games and real life.

The Role of Government and Culture on Innovation in Greek City-States :: Essays Papers

The Role of Government and Culture on Innovation in Greek City-States A simple analysis of the culture, structure and technologies of Greek city-states reveals the fact that culture plays a vital role in the development of technologies. More specifically, an analysis of the government of Greek city-states demonstrates the very influential role of culture upon technological development. The democratic form of government first seen in Greece is reflected in the structure of the city-states. The basis for this form of government, which is more sensitive to the needs of the people, can also be seen in some of the more traditional types of technological development. Water supply fits the more traditional definition of technology, shows a concern for public well being, and is apparent in the Greek city-state. Analysis of the Greek city-state is further strengthened by comparison to Sparta. This opposing city was built into a much different culture, and as a result, was structured quite differently and produced different technologies. While it is certain that more than simply culture and form of government influence technological innovation, the evidence highlighting these factors' contributions is ample. Culture influences and is influenced by the form of government in a given region. This government and culture then influence the manner in which the environment in treated, and the innovations that occur. In his chapter on Greece, Colin Chant writes: "The system of cities was also shaped by fundamental political changes" (p. 57). This statement leads into a discussion of the rise of democracy in Greek city-states. An elected assembly wielded the authority in these city-states. Chant states, "Although the development of participatory modes of government might well be seen as a product of enlightened Greek culture, the influence of the Aegean environment must also be considered" (p.57). This assertion deserves some attention, as it insinuates that macro-level forces could be more responsible for governmental evolution than micro-level changes. The statement also walks the fine line concerning the innate political nature of individuals. In his article "The Pentagon's New Map," Thomas Barnett explains that one must be very careful with this type of thinking, as it is a definite generalization to say that something is inherent in a people making them govern themselves in a certain manner. It is a small step from this type of thinking to the statement "those people will never be like us" (Barnett, p.174). Barnett goes on to explain that it was once thought that there was something innate in Russians and Slavs that prohibited them from accepting capitalism and democracy (Barnett, p.

What effect does this give, and why has Golding used such a character for a contribution to the novel as a whole? Use a study of character to justify your response, and closely analyze one passage describing Simon. The novel ‘Lord of the Flies’, written in the early 1950’s is an allegorical, adventure story; a castaway story about the loss of innocence. Within this novel William Golding presents many ideas and themes on levels which require a depth of consideration, but which can also be interpreted in different ways by all. The main theme Golding puts forward is the idea the book is based around. The island is a microcosm of the world, and so the behaviour in which the boys partake represents that of society. Therefore, the degeneration of civilization which occurs, shows that society holds everyone together, without the restraints and rules of society, man loses sense of right and wrong, and anarchy and savagery can come to light. The beast within will slowly but surely reveal itself, when there is nothing to hold it back, leading to a return to primal states, ultimately resulting in afore said savagery. The novel shows that it is Golding’s belief that the human impulse is not as deeply rooted to civilization, as it is to savagery. The novel shows our morals come directly from our surroundings, and the boys’ behaviour justifies this as their surroundings are changed. Most of the boys do encounter these changes, except for one. Simon. He stands on an entirely different plane from the rest of the boys. Although he is younger than Jack, Ralph and Piggy, he is good, pure and has the most positive outlook. He is insistent that even in the worst of situations, they will be rescued, even when the likes of Ralph are doubting the odds. Simon seems to have a spiritual human goodness which is deeply connected with nature. He is kind to the younger children, and sees the good within all. He is the first, and perhaps the only one to realize that the beast on the island is not in the physical form, but the evil which lurks within all human beings, - ‘â€Å"What I mean is †¦maybe it’s only us†Ã¢â‚¬â„¢Ã¢â‚¬ ¦.. ‘Simon became inarticulate

Nuclear Power Should Be Stopped

Since its find in 1960s by the Nipponese, atomic power had been used as one of the chief energy to bring forth power in more than 30 states in this universe. This natural resource is known as the safest energy-dense of all natural resources, where it has the ability to bring forth more electricity and heat compared to others. Unfortunately, the â€Å"March 11 temblor and tsunami† ( asiannews.net, n.d. ) had turned some portion in Japan into muddy, contaminated environment. Together with the radioactive spewed, the status in many residential countries peculiarly in Tohoku metropolis had become worse. To some people, it is being considered as a lesson that technological promotion can non ever protect states against natural catastrophes. Greenpeace, the Nipponese and Malayan authorities all have really strong points of position on the affair. In this essay I will depict and discourse their positions in order decide for myself what I believe atomic power hereafter should be. Nuclear energy derived from the interlingual rendition procedure which occurred between two dividing atoms ; Iron and smaller atoms. This was proved by utilizing Einstein ‘s celebrated expression, which is E = MC2, where M stand for mass and C represent the velocity of visible radiation ( Adamantiades, 1987 ) . In the early 1940 ‘s, research workers discovered this energy and accredited its possible to be used as a arm. Later in the 1960 ‘s, the Nipponese research workers set up several surveies and the consequence was diverting as â€Å"the newfound energy source†¦and found a place in the propulsion of the atomic naval forces, supplying pigboats with engines that could run for over a twelvemonth without refuelling† ( Adamantiades, 1987 ) . This lead to the development of atomic power where the Nipponese authorities spend more than 200 million hankerings to help atomic scientists in making engineering that could commercial the power workss. For the Nipponese authorities, the continuance of the atomic power production is important. Since the intercession of atomic power, the Nipponese had been utilizing this energy actively and until today, more than 50 reactors were built in order to bring forth this energy. This energy had already contributed 30 per centum of the state electricity and it is estimated that the per centum will be higher in five old ages. High demand for this energy from other states besides contributes to the effects. The Nipponese Ministry of Economy Trade and Industry ( METI ) reports that 60 per centum of the states in the universe that uses this energy were imported from Japan. The Nuclear and Safety Agency ( NISA ) , one of the Nipponese authorities bureaus that responsible for atomic power ordinance, licensing and safety assured that regular review has been conducted to supervise all power works therefore all citizen should non be worried. Warning dismay will be released if there any amendss in the reactors. Besides that, the authorities besides emphasize that there is an on-going research in happening ways to cut down fuel rhythm costs over the last decennaries. It will take to the cost decrease resulted from a â€Å"decrease in fuel rhythm unit costs and enhanced fuel rhythm procedure efficiency, with fuel public presentation betterment, in peculiar higher norm burn up, accounting for less than 10 per centum of the savings† ( NISA, n.d. ) . The Malayan authorities has a really similar sentiment on whether the production of atomic power should be stopped. As the universe ‘s population and living criterion are heightening, the demand for more electrical power is besides increasing. Like the Nipponese authorities, Malaysia is presently working towards implementing atomic as an alternate energy. In a imperativeness release written by Anifah Hj Aman, Minister of Foreign Affairs and Douglas Uggah Embas, Minister for the Natural Resources and Environment in 2010 they clearly province how the authorities feels about atomic energy. â€Å"Various researches and studies has been conducted to happen the best results for this affair and we think that atomic energy is one of it† , said Douglas Uggah. Besides that, they besides province that the Malayan disposal has started to recognize the importance to follow renewable energy for the state. This is because for the past half century, Malaysia has depended chiefly on oil and gas. â€Å"Being â€Å" addicted to oil † is a major national security concern for assorted grounds. Usingplug-in intercrossed electric vehicle ( PHEV ) powered by atomic reactors, we could cut down our oil demands by orders of magnitude† ( Oh Tick Hui, 2010 ) . Additionally, they besides highlighted the effects from the atomic use in making nursery gas emanation is the lowest compared to other energy. This, on occasion, will assist to cut down the pollution rate in the state. â€Å"Malaysia is one of the top 20 states in the universe with most pollution. By implementing this energy with the current system, we hope the rate of the air pollution particularly will be decrease as it does non bring forth smoke† , said Anifah Aman. When they were asked whether the consequence of the atomic waste would be a job in future, he stated that Malaysia is one of the states that are free from nature catastrophe therefore it would non be a job. â€Å"But we ever prepare f or the worse, therefore some of the safeguard will be take into consideration† , he added. ( news.malaysialivescience.com, n.d. ) While both Japanese and Malayan authorities supports the continuance of atomic power production, Greenpeace oppose it. They stated that the continuance of atomic power production, which consequences put on the lining the environment and humanity, is unacceptable. They argue atomic energy does lend to the nursery effects, clime alteration and other related catastrophes. They besides expressed their concerns as the effects â€Å"can besides result in a Chernobyl-scale accident one time every decade† ( WNO, n.d. ) regardless what atomic industry had told the world.In a recent article retrieved from www.greenpeaceinternational.com, a group of Greenpeace radiation experts blame the Nipponese authorities for the lost from the tsunami calamity, stating that the building and innovation made by the authorities are the most irresponsible in Japan history, in fact the most condemnable act of all time done on this planet. â€Å"Japan has poured in 1000000s of dollars to make high velocit y trains that can shuttle people over 100s of kilometers with speed†¦but this superb engineering that touts convenience and economic addition can non impede it from disasters† ( Greenpeace International, n.d. ) . They besides classified the Nipponese authorities and its ally action in edifice more and more atomic power works in the state as forcing away the dark history, where the power works are somewhat the most unsafe devices that adult male has of all time created and have taken infinite figure of lives. However, there is conflicting grounds on how Nipponese people view the importance of atomic power. Harmonizing to the Nipponese Nuclear and Industry Safety Agency ( NISA ) , the Nipponese economic system will non fall in although the calamity sunk its chief atomic power system. They believe that the Japanese will retrieve enormously, the same during the Hiroshima and Nagasaki calamity which was overcome in what is known as the Nipponese ‘economic miracle ‘ ( NISA, n.d. ) . Japan won regard from people around the universe for the rise of its state, bring forthing good educated young persons, and contriving an advanced engineering system. Not merely that, NISA besides sprang back Greenpeace statement stating that the engineerings finally saved more than 30 per centum of its existent lost in Tsunami calamity. In a study conducted by NISA, it was revealed that many states praise the Nipponese authorities action by making engineerings and machines that could dismay them about the nature disasters two times faster so the normal machine. This can be compared with what go on to Indonesia in 2004. Although the graduated table of the temblor in Tohoku is much higher than one that work stoppage Acheh, the Numberss of victims are 90 per centums less compared to the Indonesians which killed more than 140,000 lives seven old ages ago. ( NISA, n.d. ) In decision, with the demandof energy beginning that has been and will go on to increase each twelvemonth, I believe that the production of atomic power should non be stopped. Both Nipponese and Malayan authorities ‘s purposes for the continuance are strong and valid. Greenpeace fails to make an statement that can vie. Clearly, atomic energy has a figure of advantages that highlights its capableness in going one of the most demanding energy to the universe. It is without a uncertainty that I believe such jobs will non originate if energy providers can guarantee that they do non lend to short and long-run environmental jobs, authoritiess can vouch that energy is generated safely and will non harm both human and environment, and citizens can do certain they conserve every bit much as they can so there will be adequate beginnings for their future coevalss.

Functional Leadership Model in Healthcare Essay

The traditional leadership model focuses on three main areas which are looked at to be the core areas of leadership; task, individual, and team (Al-Touby, 1). Our text does not cover the traditional leadership model but, it does cover the path-goal leadership theory which in some sense relates to both the traditional leadership model and the functional result-oriented healthcare model. The path-goal theory focuses on the effectiveness for a leader to create high productivity and morale in a given situation (DuBrin, 147). In the path-goal theory it is important that the manager pick a style of leadership that focuses on the characteristics of the team and the demand for the task. In the traditional leadership style there is more emphasis on one core area over another; where in the path-goal leadership theory there is no emphasis on either. The path-goal theory lays the objective out in black and white. The path-goal theory is/ would be an effective leadership model for healthcare, how ever adapting it more closely to any organization would make it more effective and efficient. The main objective that can never be forgotten with healthcare is the patient’s outcome; if the outcome is lost, the leader, the team, and the task have failed. The Oman Medical Journal has perfected a leadership model specifically for healthcare facilities. The journal only compares the new healthcare model to the traditional leadership model however; it could also be compared with the characteristics of the path-goal leadership theory. If a healthcare facility focuses primarily on their individual staff characteristics, the facility will risk the possibility of losing sight of the patient’s needs (Al-Touby, 1). In any medical profession all employees are there for one reason, the patient’s service. With that being said, individual characteristics are not exactly the main concern in the healthcare leadership model. Moving on to having the task be the priority of the functional model; the task by itself remains incomplete until the patient recovers from the medical condition or the disease is managed (Al-Touby, 1-2). One patient is a task for too many people, but each employee contributes to the outcome of the patient. Lastly, healthcare leaders cannot only focus on the team, because the team has not completed the task until the patient recovers or the disease is managed. The team is combined of the individuals and the task but, in healthcare none of those elements need priority over another. Healthcare teams can work hard and be efficient and still be ineffective (Al-Touby, 2). In healthcare effectiveness must always be the goal over efficient teamwork. These examples and reasons are why the Oman Medical Journal decided to add the fourth element results or patient outcomes; and they refer to the modification as the â€Å"functional results-oriented leadership model†(Al-Touby, 3). No matter how perfect the healthcare team is; no matter how motivated the care staff is; no matter how well the care procedures are articulated and practiced, the yardstick of good healthcare leadership is patient outcomes, the results of care. (Al-Touby, 4) The functional leadership model is based on three core areas in leadership; task, individuals, and teams. All of these are important in effective leadership, however, the modified theory; functional-orientated leadership fits my lifestyle more precise. Working in healthcare and pursuing a profession in healthcare administration I can see how the typical functional leadership model does not fit the healthcare world. Patient care is the main focal point of every move made in the medical field; focusing more precisely on one of the three elements in the typical model could easily distract a leader in losing focal point on the patient’s result/outcome. Making the result the center of the three elements works. The organization I work at now uses the functional-orientated leadership model, and all our policies are based around this model. Patient’s safety and wellbeing is always priority. References Al-Touby, S. (2012). Functional Results-Oriented Healthcare Leadership: A Novel Leadership Model.

Exploration Answer the following questions in fewer than 100 words: Activity 1: Modes of Natural Selection What type of selection is taking place on Wallace Island? Explain.Directional Selection is taking place. Th e beak size is increasing on Wallace Island from 11. 85 to 19. 13, and the population is increasing as well. This is because there are more seeds available that the birds can eat. What type of selection is taking place on Darwin Island? Explain. Directional selection is taking place. The beak size increases slowly, from 12. 47 to 26. 95. The population decreased because of the lack of seeds available for the birds to eat. Explain the reason for any differences in population numbers between the two islands.The population increased on Wallace island because there were more seeds for the birds to eat, meaning there was more of a chance for them to survive and reproduce. The population decreased on Darwin island because there were no seeds for the birds to eat and without an abundant food supply they can not reproduce. Activity 2: Extinction Develop a hypothesis to predict what conditions would lead to extinction of a finch population. If there was no participation on a small island the Finch would become extinct.Which of the parameters is most important in determining whether a population goes extinct? Variance is most important What are at least two different sets of conditions that may lead to extinction? Small Island, no precipitation Small Island, No variance Summarize the steps you took to complete the experiment you designed. I set the parameters on precipitation to 0, and the island size to . 3km. I then ran the experiment for 300 years. Summarize the result of the experiment you designed. The Finch was extinct by 2033.The beak size stayed the same until extinction. Lab Summary Address the following points in a 100-to 200-word summary: Summarize the general principles and purpose of the lab. This lab is designed to help understand how precipitation, variance, and area have a role in the evolution of a species, in this case, Finches. It also explains the different types of selection. Explain how this lab helped you better understand the topics and concepts addressed this week. This lab really helped explain the concept of evolution.Not only did it cover population grown/ decrease but it also covered the changes that animals go through to adapt to their ever changing environments. Describe what you found challenging about this lab. I did not really find anything challenging about this lab. The information was very easy to understand and the set up was easy to work with after completing previous labs. Describe what you found interesting about this lab. I found it interesting to see how one parameter can have such a large effect on a species, even over a relatively small (300 year) amount of time. Evolution Lab Evolution Lab The finches on Darwin and Wallace Islands feed on seeds produced by plants growing on these islands. There are three categories of seeds: soft seeds, produced by plants that do well under wet conditions; seeds that are intermediate in hardness, produced by plants that do best under moderate precipitation; and hard seeds, produced by plants that dominate in drought conditions.The lab is based on a model for the evolution of quantitative traits-characteristics of an individual that are controlled by large numbers of genes. These traits are studied by looking at the statistical distribution of the trait in populations and investigating how the distribution changes from one generation to the next. For the finches in Evolution Lab, the depth of the beak is the quantitative trait. I investigated how this trait changes under different biological and environmental conditions.I manipulated various biological parameters (initial mean beak size, heritability of beak size, variatio n in beak size, fitness, and clutch size) and one environmental parameter (precipitation) of the system, and observed changes in the distributions of beak size and population numbers over time. Assignment 2: The Influence of Precipitation on Beak Size and Population Number The first experiment is designed to study the influence of beak size on finch population numbers. For finches, deep beaks are strong beaks, ideally suited for cracking hard seeds, and shallow beaks are better suited for cracking soft seeds.I experimented first with the finches’ adaptation and evolution of their population over 300 years, and changed the Wallace birds beak size to 28mm, and Darwin’s birds stayed at the default of 12mm. I hypothesize a since there are more hard seeds (64%) on the islands than soft seeds (4%). The birds with the smaller beak (Darwin) will not be able to get enough food which may cause some of the birds to die, resulting in a decrease in the smaller beak bird’s po pulation and an increase in the larger beak (Wallace) birds population because of the larger beak size better able to eat hard seeds.Darwin: Red Wallace: Blue I observed that the Darwin birds (smaller beak) actually grew up to about 25mm, as well as the Darwin bird’s population grew over time. The Wallace bird’s beak stayed the same as well as the population stayed steady but grew. The data actually refutes my hypothesis because I didn’t expect the smaller beak sized birds to grow to adapt to the seeds, I expected them to die off. This next experiment is designed to explore the effect of precipitation on finch beak size and population numbers.The experiment was to see how a decrease in precipitation on Darwin Island might affect beak size and how a decrease in precipitation might influence population numbers for these finches over time. I hypothesize a decrease in rain will produce more hard seeds because the hard seeds favor drought conditions, while the other seeds will not increase. And the decrease in rain may only slightly cause the finch population to decrease at first, but then will increase and stay steady as the birds have time to adapt to the drought conditions and their beaks will evolve.I observed that the beak sized for Darwin’s birds supported my hypothesis in that the birds beak sized increased with time. And the population did what I thought too, in that it decreased at first and then increased steadily. I then ran another experiment for 200 and 300 years separately. I observed that the 200 years population and beaks did about the same as the 100 year experiment. Which still confirm my hypothesis. But the 300 years, the bird’s populations and beaks sizes on both islands increased, but that the Darwin birds eventually passed Wallace’s birds in population and beak sized.I then performed the same experiment for both Wallace Island and Darwin Island simultaneously. I noticed that the 100 and 200 years beak size and population both increased and, but Darwin’s birds were still behind Wallace island birds. But then at the 300 year both beaks and populations were almost the same increase. My hypothesis on how an increase in precipitation on Darwin will influence beak size is that the beak sizes should become smaller and more shallow because the increase in rain will make softer seeds and smaller, shallow beaks are better for soft seeds. And the bird’s population will increase..I observed just what I hypothesized – the beaks grew smaller and their populations grew huge. When I reran the experiment I observed that Wallace island birds also followed the similar growth for beaks and population as the Darwin birds. When I ran the experiment by increasing precipitation on Wallace Island to 50 cm/year and increasing beak size to 28 mm, for 300 years, I observed the beak sized actually decreased slightly and the population stayed steady and in line with the Darwin birds. Next experiment I decreased beak size on both of the islands to an intermediate value. I decreased rainfall on one island to a value close to zero.On the other island, I increase rainfall close to the maximum value and ran the experiment for 300 years. I observed different effects on each island. On the Darwin island with a medium beak size and almost no rain had increase in beak size and population. The Wallace birds with a medium beak size and lots of rain had a decrease in beak size and a steady increase in population. Assignment 4: Effect of Island Size My hypothesis for what effect an increase in island size will have on beak size and finch populations is that the beak size will have an increase and population will increase.I began my experiment by leaving all other parameters at their default values. Then changed the island size of Darwin to the highest it could go to 1km. The beak sized increased as predicted and so did the population increased. When I decreased island size, the beak size grew and the population dropped off first in the beginning but then increased with time. Based on previous experiments if I decrease the clutch size the birds populations will decrease a great deal. Also if I decrease the heritability parameter, and decrease clutch size the populations decrease – which looked like to the point of extinction.
