publications review EssayA reasonable venture assessment of sex offenders, when combined with good discussion supervision and a community-based treatment schedule aimed at relapse streak, effectively reduces recidivism. This was the finding of a engage conducted by Wilson, Stewart, Stirpe, Barrett, and Cripps in Canada. Published in 2000, the study covered 107 sex offenders who were released to the custody of the Central Ontario territory during a period of eight years starting in 1990.According to the authors, their study outlined the oecumenical principles laid down by Motiuk, Belcourt, and Bonta in 1995, namely c areful and continuous evaluation of offender risk which ensures that highly dangerous offenders were non al petty(a)ed to return to the community by sentencing them to life in prison center on criminal behavior when conducting intervention programs with the help of qualified psychologists effective monitoring of the returning offenders activities in the communi ty by employing only competent parole personnel trained in the principles of relapse prevention and an honest exchange of information among the relatives of sex offenders, the parole personnel, and the treatment staff in order to reach the right mix of treatment intervention and parole supervision. Wilson et al (2000) found that the st calculategy resulted to a low 3. 7% recidivism compared to the 5. 4% cited by the study of Motiuk and Brown, and the 6.3% recidivism rate which came out of the study conducted by Barbaree, Seto, and Maric. Both studies were complete in 1996 (Wilson, Stewart, Stirpe, Barrett, and Cripps, 2000). In West Virginia, Gordon and Weldon (2003).Examined the effect of educational programs on recidivism. Studying the records of inmates who attended the General educational Development (GED) and the Vocational training programs conducted from 1999-2000 at Huttonsville Correctional Center, they found that a recidivism rate of 8. 75% was enter for those who com pleted the vocational training program. Inmates who went through both the vocational training program and the GED, on the separate hand, reported a lower 6. 71% recidivism rate.Both figures were way below the recidivism rate of 26% which was observe on inmates who did not participate in either educational program. These results were comparative to the findings of a study make by Mace in 1978 of 320 inmates who were discharged from correctional institutions in West Virginia in 1973. Out of the 320, 76 were rearrested after four years, 21 (or 6. 56%) of whom were products of educational programs behind bars while 55 (or 17. 19%) did not attend any educational program while being incarcerated (Gordon and Weldon, 2003). Meanwhile, two cost-effective programs were the hooked of an article authored by Harvey Shrum in 2004.Published in the Journal of Correctional precept, the article discussed two additive practices called logotherapy and intensive journal which, according to him, were better at reducing future criminality of both offenders and electromotive force offenders than punishment and surveillance-based programs. Logotherapy, which means health through meaning, was developed by Dr. Viktor Frankl as an effective substitute to the 12-step program of rehabilitation for drug and alcohol abusers generally accepted by most parole boards. The program aims to pass on inmates with a purpose and broadcastion in life. Introduced forty years ago to inmates of a California replacement Center, program participants reported a recidivism rate of 5. 5%. When it was re-introduced to nineteen inmates of Folsom State Prison in 1998, the one-third participants who were released on parole reported a zero percent recidivism by year 2004.Intensive journal, on the other hand, was first introduced at Folsom State Prison in 1992. Created by Dr. Ira Progoff, it is a system of self-development that makes use of writing exercises. Inmates were made to write about their experie nces, relationships with their families, their jobs and health, and the meaning that they give to their lives in a journal. These journals were reviewed and feedbacks were provided. By 2002, ten years after the program was introduced, no participant was ever rearrested (Shrum, 2004). The debate on the rate of using recidivism to measure the effectiveness and efficiency of correctional programs continues and, in fact, polarized justice scholars.A dissenting mentation was voiced by Thomas in 2005 when he said that prison facilities and programs have no trance over the behavior of inmates once they return to their communities. He argued that communities are influenced by certain social, cultural, and economic factors which are beyond the control of prison facilities. Policymakers and academics, however, refuse to budge. They insist that there is no other, better measure than the rate of recidivism. According to these academics and policymakers, effective rehabilitation measures sho uld be able to provide inmates with coping mechanisms necessary for them to deal with the economic, social, and cultural stresses of post-release life. In the same vein, they argue that effective deterrence programs should produce inmates who should have learned enough lessons during internment to dissuade them from returning to a life of crime. In both cases, they maintain that low recidivism should be the direct result. Although inclined towards the use of recidivism, Maxwell, in an article entitled Rethinking the Broad Sweep of RecidivismA Task for Evaluators, suggested that academics should not stop looking for less familiar methods of approaching the problem while policymakers should maintain an open theme so that like policy questions could be considered more objectively (Maxwell, 2005).References Gordon, H.

Steam Distillation of Eugenol Essay Example for Free

Steam Distillation of Eugenol Essay gateway This experiment involves an extraction of a natural product using the techniques of steam distillation. The principle component of crude of cloves is an aromatic compound, which is identified by thin layer chromatography (TLC).Eugenol is widely used in dentistry, due to its analgesic, purifying balsamic qualities. It is ideal for curative for pulp hyperemia (the soft, sensitive substance underneath the enamel and dentine of a tooth) and pulp its. In dentistry eugenol is alike used to cover cavities, fill canals, etc. It also keeps food fresh and kills off bacteria and viruses. Eugenol helps keep meat fresh and prevents stomach up treated, diarrhea, and wound infections. In addition, it might play a part in relieving indigestion, controlling diarrhea, and healing cuts and bites.Eugenol is the main active chemical element in cloves.Procedure1. In a 250 mL round bottom flask, place 10.0g of ground cloves and 80 mL of water. Set up fo r a simple distillation2. Heat to boiling and collect the distillate until you no longer see droplets of organic liquid coming out of the condenser (about 40 minutes).3. interject the distillate in a separatory funnel and extract with three 10 mL portions of Dichloromethane4. deepen the dichloromethane extracts and dry over Sodium Sulfate.5. Examine the purity of the extract using thin-layer chromatography (TLC). Spot a small sample of the extract using a capillary spotter about 1 cm from the end of TLC plate.6. Visualize using a UV light and mark the visualized vagrant with a pencil.7. Record the number of spots and the Rf values from the spot(s).8. While the plate is developing set up a clean and dry distillation set up and distil off nigh of the dichloromethane solvent.9. The remaining solution of Eugenol in Dichloromethane can be removed using a disposable pipette and placed into a clean pre-weighted vial.10. The vial can be heated on a steam bath under the hood to remove the small amount of dichloromethane.11. The pure Eugenol should be weighted to determine the percent oil recovered based on the mass of cloves originally used.Results constriction of Eugenol 1.34 g/mLBP of Eugenol 40CInitial mass of Eugenol 18.545 gMass of vial 18.0063 gMass of Eugenol Oil 18.434 g% Recovery= (18.545 g 18.434 g)/18.434 x 100 = 0.602%Thin layer chromatographyRf=(Distance substance moved/Distance solvent moved)Rf=(4.2/5.1)Rf=(.824)ConclusionThe experiment was successful in that we did isolate eugenol as proven by thin layer chromatography. Our Rf value was somewhat high. This is in all likelihood because the beaker with the chloroform was non 100 % closed during the time we did the thin layer chromatography. Our watch glass was not 100% efficient. Also when we were heating the liquid in the condenser, heating the liquid at a tramp too high could cause excess materials to come out in the final product.Other than that, pitying fracture is a concern. This can be minim ized by careful observation, and proper procedure. Still, our percent error was under 1 percent, which is very favorable.

Foundational Accounting Principles and Terminology Essay Example for Free

Foundational Accounting Principles and Terminology EssayWe on the whole know how valuable the report aspect of any condescension/organization is. It is basic wholey the most important way to manage finances. Without proper score for all expenses and finances, a company and/or organization forget definitely have a hard time organism mo terminalaryly stable. In this paper we pull up stakes discuss some foundational accounting principles and terminology that ar basic but quite essential to the accounting practice. Now lets discuss some accounting terms beginning with Generally accredited Accounting Principles.Generally Accepted Accounting Principles (GAAP) is a codification of how CPA firms and corporations prepargon and present their business in pay off and expense, assets and liabilities on their financial statements. GAAP is not a single accounting rule, but rather the nub of many rules on how to account for various transactions. GAAP are more like accounting standard s (Wikipedia, 2009). abutting we have Contra-Asset Accounts, which is defined as an account which offsets another account. A contra-asset account has a credit equilibrium and offsets the debit ratio of the corresponding asset.A contra-liability account has a debit balance and offsets the credit balance of the corresponding liability (InvestorWords, 2009). Let us move on to Historical Cost, which is a measure of prise used in accounting in which the price of an asset on the balance poll is establish on its nominal or original cost when acquired by the company. The historical-cost method is used for assets in the U. S. below mainly accepted accounting principles (Investopedia, 2009). Okay, now there is the Accrual Basis vs. property Bonus Accounting. This is the fight between the two.In Accrual basis accounting, income is reported in the fiscal period it is earned, regardless of when it is received, and expenses are deducted in the fiscal period they are incurred, whether the y are paid or not. Basically, you record both revenues and expenses when they occur. In bills basis accounting, revenues are recorded when cash is actually received and expenses are recorded when they are actually paid (Ward, 2009). Last but not least, there is the Accounting Standards Codification.Accounting Standards Codification (ASC) is a major restructuring of accounting and reporting standards designed to simplify user access to all authoritative U. S. generally accepted accounting principles (GAAP) by providing the authoritative literature in a topically organized structure. ASC disassembled and reassembled thousands of nong overnmental accounting pronouncements (including those of FASB, the Emerging Issues Task Force EITF, and the AICPA) to organize them under approximately 90 topics. The ASC are those that oversee that all accounting and reporting standards are adhered to (Wikipedia, 2009).It is now time to move on to discuss and describe terzetto sets of financial statem ents that are part of financial statements of companies /organizations. The three sets of financial statements we will be describing are The equilibrise Sheet, The Income Statement and The Statement of Cash Flows. The balance sheet also known as the Statement of financial position reveals a companys assets, liabilities and equity (net worth). The balance sheet is divided into two part that must equal each other, or balance each other out. The formula of the balance sheet is Assets= Liabilities + Shareholders Equity.What this formula means is that assets, or the means used to operate the company, are equilibrise by a companys obligations along with equity investment brought into the company and its retained lucre (Investopedia, 2009). Next we have the income statement, which measures a companys financial performance over a detail accounting period. The financial performance is assessed by giving a summary of how the business incurs its revenues and expenses. It also shows the ne t profit or loss incurred over a specific accounting period, which is typically over fiscal quarter or year (Investopedia, 2009). Moving on to the last one, which is the cash attend statement. The cash flow statement allows investors to understand how a companys operations are running, where its money is coming from, and how it is being spent. The cash flow statement is also a mandatory part of a companys financial report, and has been so since 1987 (Investopedia, 2009). Now I will describe which is more useful, Net Income or Cash from Operating Activities? I believe that Cash from Operating Activities is more useful to companies because they can generate cash in several different ways.Three different ways to be exact, they are cash flows from direct activities, from investing activities, and financing activities. Cash from Operating Activities, in my opinion is the most useful because it paints the best generate of how well a companys business operations are producing cash. Afte r looking over the annual financial reports for Samsung, RTL Group and Lockheed Martin, I make the prediction that each company will draw out to improve its net income as well as see a significant spike in their cash flow.As far as relevant information in regards to conglomerates, such as the IDOLS fraction of the Fremantle Media North America, I was not totally sure how to get this information but I lastly continued to read the investor portion on the RTL Group website where I found out more information. each(prenominal) in all, I learned some new definitions when it comes to accounting and decision making. I thought this grant was intense due to a lot of reading and research, but I believe I got by dint of it well. I look forward to learning more about how accounting and decision making come together.Referenceshttp//www.investopedia.com/articles/04/033104.asphttp//www.investopedia.com/articles/04/031004.asphttp//www.investopedia.com/terms/i/incomestatement.asphttp//www.invest orwords.com/5476/contra_account.htmlhttp//en.wikipedia.org/wiki/Generally_Accepted_Accounting_Principles

The people motivated Essay Example for Free

The people motivated seekThere are many different motivation theorists who each with there own theory as to the way people are motivated, exclusively do people actually be sport the way these theories bear witness us they do or are the people motivated by early(a) things. Elton mayo conducted several(prenominal) experiments in 1927-32 and found that split up lighting equalled high productivity. He set up to groups of workers these included a test group and also a control group. When he turned up the light in-group one, but not in the other productivity rose in two groups. While in progress experiments he reduced the lighting to its original level and turned the lighting up in the other group productivity still rose in both groups. The experiments showed no correlation so Elton Mayo changed the variables within his experiment. Working with a group of women, the experimenters made a number of changes, alight breaks, no rest breaks, free meals, no free meals, more hours in the work-day / work-week, fewer hours in the work-day / work-week. Their productivity went up at each change. Finally the women were put back to their original hours and conditions, and they set a productivity record.The reason for this was that both groups were being consulted and workers developed cohesiveness as a social group. This was mainly due to workers sensing belong and the UN-weighted desire for higher pay and the need for many to reach productivity targets. This showed that workers were motivated by the carrot and stick theory that people would be motivated by bonuses. An example of these ideas being used in business today is the Volvo plant in Uddevalla, opened in 1989, was designed to allow workers to work in teams of 8-10.Each team built a complete car and made decisions about production. It was found that the absenteeism evaluate at the Uddevalla averaged 8 per cent, compared to 25 per cent in their Gothenburg plant, which used a production line system. Proving t hat workers performed better when they entangle belonging to a group. Frederick Taylor took a more scientific approach to the way he felt people were motivated, but just like many other theorists he believed people were motivated by money. He believed that if output could be linked to pay then output could rise.So piece rank were introduced, an idea that meant the higher your output the higher your wage would be. However at the time this wouldnt work as many businesses didnt have management and therefor the employees were not always sure of what to do, so Taylor recommended they should have managers to have control over the work of the employees and therefor make the business more efficient. This is also a carrot and stick but the workers would be motivated to get a greater wage.

Airframe Structure Failure and Survivability Essay Example for Free

Airframe Structure Failure and Survivability Essay in that respect atomic number 18 many diametrical variables that come into be during an aircraft shot. It is an investigators job to find out what ca employ the harm. Failure of an aircraft elementary coordinate is ranked high on the cite of risks airgangs would rather non face. Mechanical component failure which end lead to bolshy of control of the aircraft is not far behind. Another issue which must be addressed in any aircraft accident is the psyche and of descend survivability. Even if no one was injured the investigator must find out what worked and what didnt. If thither were injuries, several questions should be asked. The chapters I will be c overing will give the investigator a look into what ca holds structural failure, and how to determine crash survivability. An aircraft accident investigators job is to determine what caused the crash. Structural failure is a vital part of the investigation. The term bui lding failure office where the material fails to play below it was think to carry. A structure rear fail in one of two general panaches. One way is it depose be fractured, which means broken into two or more(prenominal) pieces.Another way is when the structure shape is changed so that it sack up no colossaler carry its institutionalise. With this kind of failure, the structure is still in one piece. It could be bent, stretched, corroded, or so worn that it can no longer do its mean job. Over the next few pages, I will be going into detail about the different ways structures can fail. There ar many reasons why an airplane structure can fail. As I apply just gone over a few in the last paragraph, on that point atomic number 18 many different ways this can happen. In chapter 35, the book talks about over lodge.This is, when an in-flight clog exceeds the weight the part was designed for. All structures to include bridges, buildings or airplanes be created to oblige only when hold in lade. It is unrealistic to assume that airplanes can be designed and built to withstand any conceivable load it can experience. If a structure is exposed to a load greater than which it was designed for, it will structur alone(a)y fail. Be it deforming, or fracturing into two or more pieces. These argon two general reasons why aircraft structures fail.Aircraft structures ar designed to withstand heaps generated by air at some maximum airspeed and the loads generated trance maneuvering at some G load. Most aircraft can be flown at speeds and G loads which can place excessive loads on the aircraft structure. Aircraft that is outright exposed to onrushing air could be damaged as the energising pressure of the air stream is converted to static pressure pressing inward on the structure. Excessive speed can reduce the airplanes stability. The bottom line is that a lot of bad things can happen when an aircraft exceeds its redline airspeed.One of the cleargonst rea sons for failure of a structural component is that the component lacked the fit carriage to withstand the loads created succession the aircraft is flown at its normal operating limits. There ar numerous reasons why a structural component could be understrength. It is possible that the engineering of the structure was inadequate. The designer could set out possibly do an error which was not caught during the testing phase. Another reason could be that slang and attract caused a weakening to the structure. Service life issues be unremarkably divided into four sub areas get into cracking, corrosion, presume and creep.The four of these encourageive failures which cannot be undone as the aircraft accumulates flight hours ground-air-ground cycles. An aircraft structure can be weakened in a somewhat unforesightful flow of cartridge holder. Exposure to heat can greatly reduce a alloys strength. For mannequin, some aluminum alloys that are exposed to temperatures of 400 fo r 5 minutes can reduce the alloys strength by 80%. Jet engine hot sections and compressor bleed airlines are made of materials such as stainless steel or titanium alloys which maintain most of their strength in relatively high temperatures.This problem happens when structure which is not been designed for high temperature is exposed to high temperatures. most aircraft which can reach high supersonic speeds require the leading edge structures to be able to withstand the extremely high temperatures generated at these speeds. There are two general areas when it comes to aircraft structures. You get to a primary structure, and a lower-ranking structure. The primary structure is parts of the aircraft that are necessary to safely fly its mission.The hobby components are normally considered to be part of the primary structure wing structure, fuselage structure carrying flight, ground and confine pressurization loads, empennage, landing string structure, engine mounts and supporting structure. The primary structures can be further sub reason as either critical structure or principal structure elements. Critical elements are those whose failure would result in catastrophic failure of the aircraft. Principal elements are those that contri bute significantly to carrying flight, ground and pressurization loads whose failure could or could not result in catastrophic failure.The following components are considered to be the secondary structure aerodynamic fairings, tail cones, and landing gear doors. There are other mechanical components which carry flight critical loads. Even though these components birth failure modes that are closely related to those exhibited by the primary and secondary structures, they do not fall into either of those categories. Components like hydraulic pressure lines, flummox shafts, electric alternators, and gear teeth in transmissions all have modes of failure which can give clues concerning the character of the loads which caused them to fail.In aircraft accident investigator will have a firm understanding of the loads that airplane structured caries and the physical evidence that these loads leaves behind when they fail. The many typewrites of loads are vectors and have both magnitude and direction. You can change the load by either changing its magnitude, for example increasing or decreasing the pounds of force world applied, or by changing its direction by applying force upward instead of down. Loads can purport a finite length of succession to be imposed. Even though loads can be applied in a truly short period of time they can be applied or changed instantaneously.The fact that loads take time to apply and or change is important for the accident investigator understand. The book sepa rank loads into one-third general areas static loads, dynamic loads, and tell loads. Knowing the struggle mingled with the three types is important because the genius of the load has a lot to do with the failure of the structure and the evidence left behind. If a load were applied so slowly that the structure to which the load was being applied to stayed equal at all times the load would be considered a static load. A static load can be either for short or long period of time.A dynamic load happens when the loads are applied fast enough to pr razet the structure from carrying the load while remaining in equalizer as the load is being applied. Dynamic loads can be divided into two subcategories, sudden, and impact. A sudden load will impose stronger internal stresses in the structure. Components such as landing gear are tested with dynamic loads. Impact loads are applied at faster rates than sudden, causing the structure to fracture almost every time. Impact loads are usually limited to high-speed bird impacts and crash tests.Repeated loads are just like they straits, loads that are repeated over and over again. Due to the behavior of dynamic impacts and longtime static loads, it makes them dis similarly candidates for repeated loads. Short time static and sudden dynamic loads can be repeated over and over again. If a component goes by dint of lots of repeated load cycles before it fails due to frighten away cracking it is said to have experienced high cycle fatigue. By lots of cycles the book means hundreds of thousands or millions or tens of millions of cycles.One of the ways investigators look at structure failure is to consider the time it in like mannerk for the failure to occur. If the failure happened at the instance of a single load, it is called an instantaneous failure. If the failure took a period of time to occur, that is called a progressive failure. If a structural component contained a load that caused significant distortion, but did not exceed the materials yield stress, and the structure springs venture to its original shape after the load is aloof is called an elastic deformation/distortion failure.Now if the same events occur and the structure does not spring backward to its original shape after the load is re live ond, that is called plastic deformation/distortion. This is a permanent shape change, unlike the elastic which is a temporary shape change. Now if the load reaches the point where internal stresses not only cause significant plastic deformation, they exceed the materials ultimate stress, the structure will then fracture and decompose into two or more pieces. This is called a fracture failure. An experienced investigator can tell the difference between the five different types of structural failure.Another form that causes structural failures is corrosion. Corrosion is the natural dissolution of material as it is attacked by one or more substances in its environment. During the refining process, energy is added to metal ores and other raw materials in order to produce the mechanical properties necessary in structural components. bring Nature the great equalizer, doesnt like variances in energy levels and sets to work trying to bring the material back to the low energy levels existing in the products of corrosion.When it comes to aircraft structural components, mother natures attack will reduce the strength and ductility of components turning strong metals into meek metallic oxides, hydroxides or sulfates. If these compounds are not removed from the structure they can worsen the problem by providing an environment which is ever more favorable to continued corrosion. There are many different forms of corrosion. Some can be the result of a direct chemic attack by reactive substances in the environment. Pitting is a common form of corrosion.Small holes that are randomly located across the metal surface are called pits and sometimes may be attach to with a powdery residue. Even though pits may appear to have damaged only a itty-bitty percentage of the surface, they penetrate oceanic abyssly in a branching matter causing discharge of strength and ductility which is way out of proportion to metals surface appearance. Chemical corrosion involves the reaction between a metal structure and some chemical agent. If you introduce corrosive acid on a metal wing, the acid and the metal will react to form new and undesirable compounds.A discriminating attack is when corrosive actions seem to favor one part of the components or assembly above other. The primary type of selective attack is intergranular corrosion. This type of attack centers on the grain boundaries with in a metal component before consuming the grains themselves. Similar to pitting the damage from this kind of attack causes a loss of strength and ductility which is out of portion the amount of metal that is corroded. Another form intergranular corrosion is exfoliation, whose progress and go undetected until all structural integrity is lost.Grain boundaries attacked by this type of corrosion are normally flattened and or elongated grains of extruded or rolled metals. This type of corrosion can move undetected o n the grain boundaries. Slow removal of material from the surface of the component by a mechanical action is referred to as wear. In most cases wear is undesirable, wear during break in on new or overhauled equipment is oft a necessary ingredient in establishing proper operation and long service life. The type of wear the book talks about is the kind that leads to premature failure and breakdown. pettish wear happens when small abrasive particles cut into and remove material from surfaces of two components which are held unneurotic while moving. When this type of wear happens one question an investigator must ask is, where did the particles come from? Adhesive wear occurs when microscopic projections of the surfaces of the two components which are sliding across each other may jot, weld together and break off. A question that an investigator can ask is was the surface lubricated? Erosive wear is similar to abrasive wear in that foreign particles are cutting tiny chunks out of the surface.Its a little different from abrasive wear in that the abrasive particles gain their penetrating energy by a tranquil that is carrying them along. How did the particles enter into the fluids is a question an investigator could pose. To prevent structure failure, the components go through an inspection called non-destructive inspection (NDI). NDI are inspection proficiencys which will not do significant harm to the mark being inspected. Other names for this type of inspection is called non-destructive evaluation (NDE) or non-destructive testing (NDT).There are six specific techniques for these inspections. First, visual inspection is the simplest form and most common of the NDI process and uses your God-given gift of sight. To hang this type of inspection, illumination, magnification, and remote viewing are used to help. Another type is dye penetrant. This inspection is used to detect small surface cracks and discontinuities which may not be visible during strictly visual inspections. This technique is simple, but time-consuming. The component being inspected is covered with a colored luculent which is absorbed into surface cracks.The liquid includes a phosphorescent material which when exposed to ultraviolet light glows in the dark so small surface cracks are visible to the naked eye. Magnetic particle inspection provides another way to assistant the eye by increasing the conspicuity of a surface crack. This process requires more specialized equipment then the dye penetrant process, it makes the crack even more obvious if properly used. This inspection makes use of the fact that when a charismatic field is induced in a component made of Ferro-charismatic material, surface cracks will alter the components magnetic field.When magnetic particles are placed on a magnetized surface it will align themselves along the magnetic field showing any variations caused by the cracks. If the magnetic particles are phosphorescent and viewed in a dark room under an ultraviolet light pattern around the cracks will be more visible. Eddy legitimate is the first technique that is discussed that does not require direct viewing of the crack. This process involves the use of a probe to generate both an electromagnetic field and sense and evaluate the Eddy current generated in the material being inspected.When either or surface or near surface cracks are in the material it will alter the shape of the Eddy current and magnetic field it generates. This can be as simple as a twitch on a meters needle. The equipment involve for this type of inspection must be calibrated for the specific design being inspected and the size of the crack being search. Ultrasonic inspections make use of high-frequency sound to find surface and subsurface defects. The high-frequency sound waves are generated by a transducer and then beamed through the part being inspected.The reflective waves or the remnants of waves which penetrate the part are being measured with a rece iver and electronically evaluated. There are two different ways the sound waves can be applied to and retrieved from the part being inspected immersion of the part into a fluid which carries the sound waves to and from the part and direct contact inspection where the transducer and receiver are in direct contact with the part. The direct contact technique is much more mobile allowing use in the field of the aircraft or major fabrications. Radiographic inspection in its simplest form is not much different than that of an x-ray.Very short wave electromagnetic radiation are generated and directed through the part being inspected and towards unexposed radiographic film. Rays passing through cracks, flaws, voids and corroded areas will not be attenuated as much as put up passing through sound material. To the untrained eye, cracks, flaws, voids and corrosion may appear to be just another shadow on the film. Orientation of the x-rays so as to illuminate the discontinuities and proper in terpretation of the film are therefore important aspects in ensuring the thoroughness of the inspection.One of the issues which must be addressed in any aircraft accident is a question of crash survivability. Even if no one was injured, the question of what worked and what didnt work should always be asked. Did the restraint systems operate as designed? Whether or not escape hatches were needed, could they have been opened if needed? Did the emergency lighting system work? How crash survival equipment is designed is based on experience, history, and sound engineering judgment. To know if these components work correctly design requires an accident for verification.The accident is a chance to formalise our judgment and we cannot afford to pass it up. To make investigation of aircraft crashes a little easier requires a systematic climb by breaking down a complicated serial of events into smaller, more digestible bites. The onset chapter 36 goes over is the CREEP method. CREEP stands for Container, Restraint, Energy absorption, Environment, and Post-crash factors. The first four of the five CREEP elements relate to the dynamic portion of the crash itself.These four factors are concerned with the initial and any subsequent impacts with the terrain, the associated deceleration forces performing on the aircraft and its current occupants, and the deformation and dislocation of aircraft structure and its contents. The fifth factor relates to the occupants attempts to egress the aircraft before paroxysm additional injuries not directly resulting from the dynamic portion of the crash. In order to survive a crash it is first necessary to provide a living space for the occupants during the dynamic portion of the crash.If the space is embarrassed or punctured, the chances of survival fall drastically. This factor is container. Now if the occupants have been provided with adequate living space, the next series of questions should deal with the restraint of the crew and its passengers and equipment and components around them. Occupants of any moving vehicle must be protect from injuring collisions with in the vehicle, for example being thrown against the sides of the living space or having objects such as clog or equipment thrown at them.The strength of all restraints should be sufficient to prevent injury at the force levels which can be judge during the most severe but survivable crash. The investigator should examine all restraints system failures to determine if there failure contributed to injuries experienced by the crew or passengers. The deceleration forces created during a crash may be high enough to cause fatal or serious injuries, even if a safe living space, adequate crew and passenger restraints, and a delethalized flailing envelope are provided.Since crew and passenger bodies are not strongly attached to the airframe, the design of the aircraft structure and seeds may cause the acceleration forces experienced by the crew and passe ngers to be either amplified or attenuated. A soft deep endow cushion can greatly amplified the vertical Gs experienced by someone sitting in the seat. The deep seat cushion deforms at high loads absorbing energy as it gives can greatly reduce the vertical crash loads to which a seat occupant is subjected.Hopefully, the designers will build a secure box around the crew and passengers and secure them to it. Although we may be able to restrain the torso, it is normally impractical to secure the head and limbs of the crew and passengers. The volume through which the unrestrained extremities can be expected to move shouldve been the legalized to the maximum degree possible. Obstructions which could cause injury should either remove from within the flailing envelope or padded to reduce the severity or probability of injury. This is the environment that the creep method covers.All too commonly, crew or passengers survived the dynamic portion of the crash, only to suffer additional injuri es or death when they are unable to safely exit the aircraft in a timely manner. The two primary factors in the reason of fatalities during otherwise survivable crashes is, post-crash fire and inability to quickly exit the damaged aircraft. Fire is the most significant post-crash accident by a long shot. Not only can the fire kill and injure directly through heat, the toxic fumes and smoke produced when material and the aircraft interior burn are more often the direct cause of death.This post-crash condition is a top priority in controlling to prevent death. radiation pattern of airplane exits is predicated on the normal parked attitude and configuration. Obviously, this is not always the case. Sometimes occupants will have to exit from an airplane that is an abnormal attitude and perhaps in a very unusual configuration. surgical incision 125 airplanes have specific emergency exit acquirements levied on them, many general aviation airplanes have only one exit which can be easily jammed in the airplane ends up inverted.In conclusion, nobody is expert on all types of structural failures. With so many different variables, it takes a highly detailed investigator to pinpoint what kind of failure causes a crash. And without a systematic approach of investigation of a crash, the investigators are left with an accident that is difficult to determine whether or not the occupants should have survived the impact.

Effective Human Resources Leadership for Nursing Home and Assisted Living Facilities Essay Example for Free

Effective world Resources leading for Nursing main office and Assisted Living Facilities EssayManagement Style for Assisted Living and Nursing Home Facilities Human Resource Management in Healthcare arrangementsThe type of government I chose to discuss is an independent the back up living facility and nursing household. They both provide some of the same functions, although the name of the facility may be slightly different. While these are separate types of organizations now, in the future, they give blend due to the point that the longer the clientele is a resident of the Assisted Living Facility (ALF), the more likely they pass on be in regard of full-time nursing care. (NursingCenter). I chose this particular type of organization because it is one(a) that I am interested in due to the fact that such a large sight of our population get out be served by these organizations in the near future and for some time to tot up based on our aging population statistics. Forty-two percent of the population that lives until the age of seventy will spend time in a nursing home before they die. (Knickman).Residents, or longanimouss, in those facilities will receive services from a variety of providers like physical and occupational therapists, medication dealment for amiable and physical ailments and perhaps social service support services as they move toward the nursing home in lieu of assistance from family members when they nominate none to call for assistance. Because the surroundings is clinical and service lie over longer periods of time, it is important to examine what kind(s) of management path is successful in order to manage the intensive daily clinical necessitate and the ongoing relationships that develop among the mental faculty and residents.One report on the study of leadership styles suited for nursing homes and assisted living facilities reported that a consensus leadership style had a strong association with quality of care. (Castle). Models indicate that consensus leadership style is also the best cuddle in limiting staff turnover, which is essential in how the residents rate their satisfaction of service. (Donoghue).Consensus management style is not a majority vote. After management hasreached a decision, consensus approach seeks to determine if all the team members come upon it acceptable and if they are in support of the decision. In this management style we would ask what could be changed in order to obtain staff support. All members of the free radical should feel that their ideas and views were heard and that they heard the others in the group as well. The idea is that the team will support the management because decisions were arrived at fairly. (Mayoclinic).To meet all the demands of transmittal control, government regulations, service to the residents, clinicians, families and inherent risks associated with the geriatric population, management must not only be caper oriented, exactly peo ple-centered. Management must develop clear and effective strategic plans, but with a human-centred approach of consensus so that all the team members that serve the clientele are happy and effective. It is truly an environment where management must foster employee relations which will decrease risk, and improve patient satisfaction which should in turn also reduce marketing needs as each point of contact that the staff has with a family member is also an ambient sales opportunity.In order to meet the patient needs in such a richly demand environment where a majority of the time the patient/customer is in contact with a lower educated, less clinical staff such as a certified nurse assistant making a low wage, that staff must have a voice to understand that they make a huge impact on the organization. When they feel valuable, the organization will run much more smoothly. My first job and customer training out of high school was working the front desk of a four star hotel. We were th e lowest paid on the totem pole, but management and human resources through incentive programs and awards recognized our achievements and solicited our input of ideas at all times.WORKS CITEDCastle, N., Decker, F.

The Mycenaean warfare Essay Example for Free

The Mycenaean war removede EssayThe Mycenaeans were a people preoccupied with war How conclusively do the various types of archaeological distinguish we hire for the Mycenaean warf atomic number 18 and defence support this statement? The Mycenaean age began or so 1600 BC and came to end near 1100 BC. Although this period was distinguished by its warriorlike aspects, I would take issue with the statement that the Mycenaeans were preoccupied by war. The first manifestations of the Mycenaean civilisation were build in the Peleponnese, especially in the north-east and the south-west. By around 1400BC the Mycenaean civilisation had penetrated the smashinger part of of import arena Greece and later still the civilisation seems to take up expanded far beyond the main frame of Greece. Excavations harbor revea lead Mycenaean remains in southern Italy, Egypt, Sicily, the Dode evictese, the Cyclades, Cyprus, and sites in Asia Minor. tell apart of Mycenaean settlements has been b eyond a doubt found in Rhodes and in Melos. These settlements whitethorn spend a penny been a general elaboration of the Mycenaean civilisation yet large meats of Mycenaean imports as found at Cyprus indicate to many archaeologists that these may be trade outposts.General enlargement would make war necessity rather than a chosen pursuit as the civilisation would feed to take new land whilst defending what they already had. Like all of the civilisations of the time the Mycenaean civilisation was agriculturally based, the Linear B tablets lean many farmers crops and in any case the percentage to be given in tax to the king and the percentage to be given to the shrines of the area. The fact that both the palaces and the shrines received a percentage fires to me that the civilisation was equally concerned with overt life as hale as war, which the palaces control conduct.Much of the crop would be dropd in the local anaesthetic area however, the surplus would be exported by d int of the business points, where a complicated form of bartering was employ as payment. It is disfranchised to chthonicstand why in a society that had such an organisational system for the listing and trading of goods, particularly agricultural goods, has no demean of an organised army if they were preoccupied with war. Although Linear B tablets record lists of men assigned to military and naval duty it seems there was no permanent specially practised force it is more likely that every man was expected to carry a weapon and use it when called up for military duty.One theory may be that the Mycenaean civilisation might have had a lack of human resources since the original inhabitants who it has been argued could have been tribes of people who lived in Greece but were not citizens and were neer trusted with military service. There are indeed records of many occupations including cabinet makers, perfume makers and still so a physician is menti one(a)d in the tablets declarei ng wider career options than simply the military. Infrequently and in downhearted numbers allys are mentioned on the Knossos tablets who could have been the occupants of the warrior tombs found in the vicinity.They probably were specially trained leaders who would organise the recruited armies in times of war rather than the liaison officers they were first thought to be. One tablet has revealed the sectors delegated to each Follower with the concentration of the Followers cosmos in problem areas such as the Bay of Navarino in the southern area of the west coast and the coastal end of the Kiparissia river valley in the north. This indicates small battalions of recruited spends led by an experienced officer in areas most likely to be attacked.Due to the general expansion of Mycenaean civilisation and the vapourific times in which there were many small kingdoms around the Mycenaean borders, defence was essential in the civilisations survival. Evidence too, can be found in the def ensive capabilities of the Mycenaean fortifications, which on the whole were built for the possibility of attack and of sieges. All of the citadels commanded wide views Mycenae having a view crosswise the Plain of Argos to the sea and even Pylos has an extensive view of the coast.These views gave the citadels early warnings of approaching forces and probably the time in which to move the people who lived around the citadel into safety behind the walls, a similar tactic to the shack towns in Troy. This cannot be proved, however, as the buildings suggest that the usual occupants of the citadels would be the royal family, priests, craftsmen and occasionally guests. Most of the citadels, excluding Pylos, were heavy fortified and built on acropoleis.The walls at Mycenae are between 5. 5m and 7.5 thick using such wide stones that the walls became known as the Cyclopean walls as peasants marvelled that they must have been built by giants. The walls of Tiryns are even more massive than Mycenae but quite different in style all the outer walls being immensely thick and with chambers built into the south side. There are hardly a(prenominal) entrances for most sites and the entrances that the sites do have are very well protected. At Mycenae both the Lion gate and the Postern gate have defences on three sides (see figure 1, page four) and in particular on the shield-less side of an approaching soldier making attacking the entrances very difficult.The main entrance to Tiryns was up a long ramp under the eastern wall which exposed the attackers all the way on their unshielded sides, this main entrance led to an opening 4. 5m wide with walls 8m thick, there were two gates beyond the first making the entrance or so impenetrable. In the case of a siege fresh water was available in both Mycenae and Tiryns through underground cisterns suggesting that sieges took place quite often at this time and the Mycenaeans wished to prepare themselves for them.Attacks could be launche d from a citadel under siege implied by the sally port in Mycenae from which it would be relatively easy for small bands of men to slip in and out without being noticed. All in all the highly defended citadels suggest the Mycenaeans feared being attacked, making the overall culture at the time seem quite warlike and volatile the Mycenaeans could simply have been fitting into the trend of the area rather than beginning one.Despite this there can be no doubt that the Mycenaeans were warlike in many respects, they are renowned for their fighting powerfulness many scholars believe that they probably conquered Knossos in Crete and ruled there for sometime. The coming of the Mycenaeans certainly brought a hammy change to the Cretan society, the warrior tombs around Knossos yielded large amounts of weapons and armour. Documents at Knossos also recorded lists of armour and weapons, one document listed exquisite linen paper for a tunic and on the second line mentions tunic fittings (epik hitonia) and 1kg of bronze. It has been argued that the bronze could have been a unit of exchange but it is more likely that the document is refering to a reinforced tunic. The same amount of bronze is used, as tunic fittings could have been a cape or overcoat to protect the soldiers amphetamine arms and the shoulders. An even more detailed, incomplete series of documents describes armour in more detail body armour, a helmet (korus) with four helmet accessories, two cheek pieces, two shoulder pieces, and an unknown number of further accessories.The helmet accessories could have been metal reinforcing plates over a leather or felt base. The accessories (o-pa-wo-ta) were probably plates of metal that were hung on to a tunic to protect the soldier, yet the arrangement of the plates is debatable with many scholars over the world disagreeing with each opposite. The glaring ideogram from Pylos of a head-dress and corslet offers no clue to the arrangement, with there being too few plates for cuticle armour.We know that they did have leg and lower arm guards such as the Dendra armour, the leg guards were probably linen as shown in late Mycenaean art, but a few bronze ones have been found possibly to be worn over the linen ones. As John Chadwick states the Mycenaean warrior, however well armed, is incomplete without means of locomotion. It is probably the case that the larger part of the army moved on plunk many, we presume, travelled to the battlefield in carrys such as the one depicted in a paint at Pylos (see figure 2, page five).Chariots can also be read of in many tablets and seen on numerous vase paintings yet payable to their impressionistic style or the damage that time has inflicted it is hard to generalize what they actually looked like. The chariots had four-spoked wheels, a fixed axle and were probably very lightweight built out of wood and wickerwork. A fresco at Hagia Triada in Crete points towards there being hide-covered bodies. Two horses proba bly pulled them, unlike the chariots depicted in the frescoes, as we know from the remains of horses that they were very small breeds.Whether or not the chariots were used actually used in battle, repayable to the rough terrain and the implications of the Iliad many scholars believe that the chariots were actually used as taxis to the battlefield. Yet it is hard to believe that only soon after the chariot Battle of Kadesh in 1285 BC that no-one was using chariots in battle, the Mycenaeans neighbours, the Hittite certainly used the chariots in battle. One inventory found in armoury of Knossos lists 340 chariot bodies and 1,000 pairs of wheels, this ratio of 31 suggests they were intended for more strenuous duties such as fighting.A fresco in Pylos shows two youths attacking a group of men with short swords or daggers, the distinction seems as difficult to understand wen it comes to the tablets as the ideogram could show either a sword or a dagger. The word pa-ka-na could be the Home ric word phasgana but there is evidence that the word may also be a confusion of the original Mycenaean meaning. One of the main reasons for war and expansion may have been the need to secure the Mycenaeans supply of metal brought to Greece through sea-borne trade.Interruptions in the trade routes could have had a detrimental effect on the Mycenaean civilisation it has been argued that the Grecians may have attacked Troy due to the equally strong civilisations control on the trade routes. The Mycenaeans chief metal was bronze, as they did not have the technological skill to extract and make good iron. Bronze is an alloy made from slob and tin, with the copper coming from Cyprus, the source of the tin is debatable as it could have come from Spain, what is now Czechoslovakia or even Britain.Chadwick argues that the Mycenaeans may have even had small amounts of tin in the land, this I doubt as such a source would surly been mentioned in the tablets. Where ever the metals came from to make the Bronze it was very valuable and the tablets suggest tightly controlled by the palaces who assigned the metal to specific craftsmen and weighed the goods produced. Although bronze was used for making weapons it also had other uses such as to make vessels and perhaps have been used to make various tools.It has been argued that the Mycenaeans had to expand due to the certain lack of these resources, which were used to make most tools and weaponry. The Mycenaeans imported much of these metals probably in sideboard for large amounts of surplus crops. The Mycenaean civilisation came to an end around 1100BC in a series of disasters and fires, one of the first places to be destroyed was Pylos invaded by an unknown adversary. Writing skills disappeared, only to be rediscovered by the Greek hundreds of years later who adapted the Phoenicians techniques.Foreign trade on a large scale also halted and the population became segregated, splitting into small rural settlements rather than the cities they once inhabited. This decay of a once great society took place over an extended time period starting with the destruction of a few cities in 1250BC and has been blamed on Dorian invasions, climate changes or internal struggles. There is no evidence that proves any of these arguments but it is obvious that the volatile times in which the Mycenaeans lived in finally destroyed the civilisation.My main argument against the opinion that the Mycenaeans were preoccupied with war is that they did bring structure into the areas in which they inhabited. Although they were obviously a warlike culture they had strong systems when it came to trade, religion, craft and administration proved most finally by the fact these structures collapsed when the Mycenaean civilisation ended.Bibliography The Mycenaeans by Lord William Taylour The Mycenaean civilisation by John Chadwick http. //www. lfc. edu/academics/greece/BrzMyc. html http//www. portergaud. edu/cmcarver/myce. html.
