Police Photography essays
Police Photography essays Photography has always played a very important part in policing. In fact, photographs have many different functions in policing. It acts as a tool to solve crimes, when it can be used as evidence against a criminal. It also helps to deter crime when it is used as a public awareness medium. However the recent developments in photography has revolutionized policing and offers many advantages to the law enforcers to solve crimes. Perhaps the most important technological change that ensured the effectiveness of police photography was the fact that the police could use high speed films and cameras that could ensure good pictures even when the subject was moving or refused to stand still. This was in stark contrast to the earlier years when the culprits or suspects used to move deliberately in order to render the photograph useless and ambiguous. After the high speed films and cameras made their mark, the long distance cameras became a boon to the police department in their efforts at long distance surveillance and criminal monitoring. This was specifically required to track down prominent criminals and to keep a tab on their daily activities. The advent of the compact movie cameras also enhanced the effectiveness of the police and helped them a lot on their routine surveillance duties. The modern gadgets that are available to the police officers for recording the events in a crime scene are necessary to pinpoint the role of the criminal and to prevent his escape from the law. For example, the modern SLR (Single Lens Reflex) cameras allow police officers to shoot a scene in their perspective. This allows them to capture images of sensitive data which may be lost in conventional cameras. SLR cameras always are reliable when it comes to photographing evidence that may be liable to be lost soon from the crime scene, and so does not allow the officers with a second chance to shoot the scene. In addition, the digital technology also has rev...

The Significance of Fish in Chinese Language
The Significance of Fish in Chinese Language Learning the word for fish in Chinese can be a highly useful skill. From ordering seafood at a restaurant to understanding why there are so many fish themed decorations during Chinese New Years, knowing how to say fish in Chinese is both practical and an insight into cultural values. Deconstructing the Chinese word for fish includes learning about pronunciation and its evolution from pictograph to a simplified character. The Chinese Character for Fish The Chinese character for fish, written in the traditional form, is é Å¡. The simplified form isÂ é ± ¼. Regardless of what form it is written in, the word for fish in Chinese is pronounced like you. Compared to English, the Chinese yà º has a shorter, more relaxed ending, dropping the exaggerated w sound that rounds out the big, full vowel in you. Evolution of the Chinese Character for Fish The traditional form of the Chinese character for fish evolved from an ancient pictograph. In its earliest form, the word for fish clearly showed the fins, eyes, and scales of a fish. The current traditional form incorporates the four strokes of the fire radical, which looks like this (ç ¬).Perhaps this addition suggests that fish is most useful to human beings when it is cooked. Radical This character is also a traditional radical, meaning that the primary graphical component of the character is used as a building block in other, more complex Chinese characters. Radicals, also sometimes called classifiers, ultimately become a shared graphical component for several characters. Thus, the Chinese dictionary is often organized by radical. Many complex characters share the radical that derives from fish. Surprisingly, a lot of them are not related to fish or seafood at all. Here are some of the most common examples of Chinese characters with a fish radical. Traditional Characters Simplified Characters Pinyin English å… «Ã¥ ¸ ¶Ã© Å¡ å… «Ã¥ ¸ ¦Ã© ± ¼ bÄ di yà º octopus é ®â€˜Ã© Å¡ é ² é ± ¼ bo yà º abalone æ •é Å¡ æ •é ± ¼ bdžyà º to catch fish ç‚’é ·Ã© Å¡ ç‚’é ± ¿Ã© ± ¼ chÇŽo yà ³u yà º to be fired é‡ £Ã© Å¡ é’“é ± ¼ dio yà º to go fishing é ± ·Ã© Å¡ é ³â€žÃ© ± ¼ à ¨ yà º alligator; crocodile é ® é Å¡ é ® é ± ¼ guÄ « yà º salmon 金é Å¡ 金é ± ¼ jÄ «n yà º goldfish é ¯ ¨Ã© Å¡ é ² ¸Ã© ± ¼ jÄ «ng yà º whale é ¯Å é Å¡ é ² ¨Ã© ± ¼ shÄ yà º shark é Å¡Ã¥ ¤ « é ± ¼Ã¥ ¤ « yà º fÃ… « fisherman é šç « ¿ é ± ¼Ã§ « ¿ yà º gÄ n fishing rod é šç ¶ ² é ± ¼Ã§ ½â€˜ yà º wÇŽng fishing net é ¦ é ¦ shÄ shark family(including rays and skates) é ¨ é ¨ tà ºn leatherfish é ®Å¡ é ²â€™ jià © oyster é ®Å¾ é ²â€¢ à ©r caviar; roe/fish eggs é ¯ é ² gÄ›ng blunt; fish bones; unyielding é ¯â€" é ² qÄ «ng mackerel; mullet é ¯ ¨ é ² ¸ jÄ «ng whale é ±Å¸ é ²Å½ hà ²u king crab Cultural Importance of Fish in China The pronunciation of fish in Chinese, yà º, is a homophone for â€Å"affluence†or â€Å"abundance. This phonetic similarity has led to fish becoming a symbol of abundance and prosperity in Chinese culture. As such, fish are a common symbol in Chinese art and literature, and they are particularly important in Chinese mythology. For instance, Asian carp (as they are known in the U.S.), are the subject of many Chinese lyrics and stories. The character for this creature is é ² ¤ é ± ¼, pronounced lÇ yà º. Pictures and depictions of fish are also a common decoration for Chinese New Year. Fish in Chinese Mythology One of the most interesting Chinese myths about fish is the idea that a carp that climbs the waterfall on the Yellow River (known as the Dragon Gate) transforms into a dragon. The dragon is another important symbol in Chinese culture. In reality, each spring, carp gather in great numbers in the pool at the base of the waterfall, but very few actually make the climb. It has become a common saying in China that a student facing examinations is like a carp attempting to leap the Dragon Gate. The dragon/carp relationship is referenced in popular culture in other countries through the Pokà ©mon Magikarp and Gyarados.

Summary - Essay Example In order to attain the primary aim of the research, questions such as â€Å"what is the median temperature at which intracellular ice formation occurs in human oocytes?†â€Å"How readily does intracellular ice formation (IIF) occur in human oocytes?†and â€Å"what is the effect of extracellular seeding on human oocytes?†(Trad et al. 1572-73). These questions were answered through an experimental design that used failed-to-fertilize and fresh oocytes with a germinal vesicle and polyspermic eggs. This design included visualization of how IFF first occurred at a cooling rate of 120OC/min using a programmable thermal microscope stage attached to a video microscope (Trad et al. 1574). It also involved execution of extracellular seeding at a cooling rate of 0.2 OC/min in order to decrease the occurrence of IIF and in turn increase survival rates of the freeze-thawed human oocytes. The design also used distinct cryoprotectants and decreased the median temperature in both mouse and human oocytes (Trad et al. 1575). The study portrayed that IIF occurs enthusiastically in human oocytes, and detrimental IIF can be avoided, and survival rates maximized. The results portrayed a 78%, 33% and 0% occurrence of IIF, and the 24 h post-thaw survival rate was 32%, 56%, and 93% respectively (Trad et al. 1576). Trad, Fouad S., Mehmet Toner, and John D.

Tort Law Essay Example for Free
Tort Law Essay After reviewing the facts, I would advise Jason, Penny and Fancy Fashions, Ltd. of their possible causes of action vis-à -vis the parties who may be held liable for damages for their negligence, namely, Alice, Joyce, the junior doctor, the nurse who administered the anti-tetanus serum, and Richard’s Teaching Hospital.            In particular, I would advise Jason to take legal action against Alice, the learner driver, for damages sustained by him as a result of the collision with her automobile. My advice is based upon the fact that Alice is liable for actionable negligence. Traditionally, the elements of a cause of action for negligence are: (1) a duty to use reasonable care; (2) a failure to conform to the required standard; (3) a reasonably close causal connection between the conduct and the resulting injury, commonly called â€Å"proximate cause†or â€Å"legal cause†; and (4) actual loss or damage to the aggrieved party (Prosser 1982).    Alice did not comply with her duty of seeing to it that her act of driving does not result in injury to another.   Knowing that she must be particularly careful at a road portion designated for people crossing, she should have slowed down.   Her not exercising reasonable care while driving is the proximate cause of the accident, which resulted in actual damage to Jason.            I would, however, caution Jason that the task of proving the negligence of Alice would not be easy or simple. The fact of the accident occurring having been proved, Jason would now have to show that Alice was negligent, and that such negligence is the proximate cause of his injury. To do this, he has to show that Alice fell short of the standard of care required, that is, she failed to do â€Å"what a reasonable, prudent person would do under the same or similar circumstances†(Prosser 1982).  Jason may argue that in determining negligence, the law makes no distinction as to whether or not the defendant is a learner driver or an experienced professional, that what is expected of Alice is that standard of care expected of a reasonable man  in order to prevent a foreseeable wrong.  A reasonably diligent person ought to be aware that pedestrian crossings are designated passageways for people and that it is a basic rule among motorists to exercise due care when approaching such crossings.  As every learner driver ought to know, one of the fundamentals of safe driving is to be always alert at pedestrian crossings; traffic signs are adequate warning to this effect.  Thus, a reasonably diligent driver should approach such crossing with caution by slowing down , his foot poised to hit the brake pedal if necessary. Judicial notice may be taken of the fact that braking is one of the first skills taught a learner driver.            In fine, Jason would have to satisfy the court: (2) that the negligence of Alice is the proximate cause of Jason’s injury, and (2) that there is no contributory negligence on his part.            Proximate cause has been defined as â€Å"that act or omission which immediately causes or fails to prevent the injury; an act or omission occurring or concurring with another which, if it had not happened, the injury would not have been inflicted.†(Tennessee Trailways, Inc. v Ervin, Supreme Court of Tennessee, 1969).  In the instant case, the omission of care on the part of Alice as she approached the pedestrian crossing would have prevented the accident; thus her negligence is the proximate cause of it. Jury instructions in the state of Texas define proximate cause as â€Å"that cause which, in a natural and continuous sequence, unbroken by any new and independent cause, produces an event, and without which cause such event would not have occurred; and in order to have a proximate cause the act or omission complained of must be such that a person using ordinary care would have foreseen the event, or some similar event, which might reasonably result therefrom. There may be more than one proximate cause of an event.†(Prosser 1982).            Since contributory negligence either bars the victim from award of damages or reduces the amount thereof, the defendant would probably adduce evidence of contributory negligence on the part of Jason.   Alice may contend that Jason is solely to blame for the accident. He should have realized that in his drunk condition he is prone to danger from passing vehicles.     Alice would attempt to show that a drunk person may not invoke his state of intoxication to evade responsibility for his own negligence, and that Jason ought to have foreseen the possible consequences of his crossing the street while drunk.            In U.S. courts where the doctrine of contributory negligence is still in force resort has sometimes been made to the old common law doctrine of â€Å"last clear chance†: a plaintiff is allowed to recover damages upon showing that the defendant had the last clear chance to avoid the accident. Under this doctrine, the later negligence of the defendant makes him liable for negligence on the assumption â€Å"that he is the more culpable whose opportunity to avoid the injury was later.†(Kansas City Southern R. Co. v Ellzey (1927) However, the said doctrine is history for being manifestly â€Å"inequitable in its operation because it fails to distribute responsibility in proportion to fault.†(LI v Yellow Cab Co. of California Supreme Court of California, 1975).    In the United States, the last clear chance doctrine appears to have been modified or superseded by the theory of comparative or gross negligence or a combination of both, and the issue of determining the best principle to be applied in such cases is now being shifted to the legislative branch.            In the United Kingdom, contributory negligence is provided under statutory law.  A plaintiff who is found to be liable thereto may recover damages subject to a reduction to an extent to be determined by the Court.  As provided under Section 1(1) of the Law Reform (Contributory Negligence) Act of 1954, in cases where contributory negligence occurs, â€Å"the damages recoverable in respect thereof shall be reduced to such extent as the Court thinks just and equitable having regard to the claimant’s share in the responsibility for the damage.† In view thereof, I would advise Jason that the damages to be awarded him in case of a favorable verdict shall be reduced as the Court shall see fit upon a finding of contributory negligence on his part.            Regarding the question of whether or not Jason’s act of walking in the pedestrian crossing while drunk constitutes contributory negligence, I submit that, yes,  it may possibly be so construed.  Alice may invoke the aforesaid statutory provision stating that contributory negligence occurs when there is a sharing of fault by both parties.  She may likewise cite the ruling in Froom v Butcher (1976), where the Court held that â€Å"negligence is a man’s carelessness in breach of duty to others. Contributory negligence is a man’s carelessness in looking after his own safety. He is guilty of contributory negligence if he ought reasonably to have foreseen that, if he did not act as a reasonable prudent man, he might be hurt himself.†   However, I maintain my position that Jason’s crossing the street â€Å"oblivious to all traffic†does not ipso facto show that he was aware of a foreseeable harm to himself.  A person crossing a street is not expected to be always on the lookout for learner drivers while doing so; they rely on the fact that any motorist is aware of its being a pedestrian crossing and should observe proper care when approaching and passing through it.  Every pedestrian or motorist always assumes that the other person behind the wheel knows what he is doing. Whether drunk or alert, one cannot possibly foresee that a particular motor vehicle is being driven by a negligent driver. In the case of O’Connel v Jackson (1972) (where an employee rode on a traxcavator against orders, thereby exposing himself to danger, and was crushed when another vehicle rammed into it), it was opined that â€Å"foreseeability is not the decisive test of causation. It is often a relevant factor, but it is not decisive.†  Inasmuch as foreseeability is not decisive, Jason may disprove contributory negligence by showing that he could not have foreseen being struck by a learner driver’s car as he crosses the street. I submit that Alice may not evade liability through negligence by showing that she could not have foreseen that a drunk person would ignore the flow of traffic.   If that reasoning were allowed,  a lame person, an unassisted child or elderly person, a blind man walking with a cane, or any person with disability who take the pedestrian crossing (and who are perfectly aware of the possibility, however remote, that they would be hit by an oncoming car) would also be liable for contributory negligence in the event of an accident.            Contributory negligence must be proven in court; it cannot be presumed. In a U.S. case, the plaintiff was injured by a passing train owned by the defendant who was then walking â€Å"on defendant’s right-of-way along a much-used path at the end of the crossties of its main track†and was hit by an open car door. The jury found that â€Å"plaintiff’s injuries were caused by his own negligence.†However, in a certiorari before the Circuit Court of Appeals, the appeals court held that â€Å"the evidence required a finding that plaintiff was guilty of negligence that contributed to cause his injuries.† Accordingly, judgment below was reversed. (Erie Railroad Co. v. Tompkins (1938).   Thus, a very drunk person crossing a street cannot be presumed negligent; his contributory negligence must be proved to bar a claim for damages.            As regards the liability of the ambulance driver, I submit that both Jason and Penny as well as the owner of Fancy Fashions Ltd. have a possible cause of action against Joyce, the driver of the ambulance owing to his presumed negligence.    The fact that the accident occurred while he was in an emergency situation does not free him of responsibility. Citing several U.S. court decisions, Prosser (1982) noted: â€Å"It is obvious, and elementary, that the care required by the standard of the reasonable man will vary according to the risk. As the danger increases, the actor is required to exercise caution commensurate with it, and to be more careful.†He also took note of other decisions which insist that â€Å"there are no degrees of care but merely amounts of care, greater or less, that the care required of the actor is always the same under the traditional formula, that of a reasonable man under like circumstances; and that the greater danger, or the greater responsibility are merely circumstances that require of him a greater amount of care.†           In proving the negligence of Joyce, the crash of the ambulance driven by him into the shop of Fancy Fashions, Ltd. is a case where the maxim of res ipsa loquitor may be applicable.  A Tennessee court held: â€Å"Where a motor vehicle, without apparent cause, runs off the road and causes harm, the normal inference is that the driver was negligent, and res ipsa loquitor is usually held to apply†(Tenessee Trailways, Inc. v Ervin (1969).  However, pursuant to the said doctrine, the running off the road of a vehicle may not be construed as negligence per se, but only gives rise to three different effects: â€Å"(1) It warrants an inference of negligence which the jury may draw or not, as their judgment dictates. (2) It raises a presumption of negligence which requires the jury to find negligence if defendant does not produce evidence sufficient to rebut the presumption. (3) It not only raises such a presumption but also shifts the ultimate burden of proof to defendant and requires him to prove by a preponderance of all the evidence that the injury was not caused by his negligence.†  If Joyce would be able to show that he did exercise reasonable care in driving the ambulance, and that there was an intervening cause (such as a third party that could have caused him to swerve off the road), the presumption of negligence arising from the maxim of res ipsa loquitor would be overcome.            The three plaintiffs may implead in their action the employer of the ambulance (St. Richard’s Teaching Hospital), being jointly liable for failing to exercise due diligence in the hiring of driver.   Under the principle of vicarious liability (respondeat superior), the employer is responsible for the negligence of his employee which results in injury to another.  Pursuant to this doctrine, â€Å"an employer will be liable for the negligence of an employee committed while the employee is acting in the scope of his employment. An employee acts in the scope of his employment when he is doing something in furtherance of the duties he owes to his employer . . .†(Lundberg v State Court of Appeals of New York, 1969).            With respect to the damage sustained by Jason arising possibly from the administering of antibiotics, I would advise Jason that he may have an actionable right against the junior doctor (and against the hospital for vicarious liability), provided that Jason would be able to produce expert testimony that the combination of alcohol and antibiotics, with or without the jolting caused by the ambulance crash, would have produced the injury, and regardless of whether or not the junior doctor consulted the surgeon.   I base my advise on the doctrine of informed consent which requires a physician to fully disclose to his patient the possible consequences of a given treatment.    In Scott v Bradford (1979), the Supreme Court of Oklahoma stated:                        the law does not permit a physician to substitute his judgment for that of the  patient by any form of artifice. Consent to medical treatment, to be  effective, should stem from an understanding decision based on adequate   information about the treatment, the available alternatives, and the collateral  risks. . . If a physician breaches this duty, patient’s consent is defective, and  physician is responsible for the consequences.            As in the case against Alice, I would advise Jason that the recovery of damages against the junior doctor would depend upon the findings of the trial court, i.e., a question of fact to be determined on the basis of the evidence.  Moreover, the defendant physician may contend that the doctrine of informed consent is not absolute; there are exceptions, such as when the information is already obvious or known, or in case of an emergency wherein the information might alarm the patient and aggravate his condition. The doctor might contend that since his primary duty is to do what is best for his patient who is unconscious anyway, he cannot be held liable for withholding information. As enunciated in Canterbury v Spence ( 1972), â€Å"the patient has the burden of going forward with evidence tending to establish prima facie the essential elements of the cause of action.  The burden of proving an exception to his duty and thus a privilege not to disclose, rests upon the physician as an affirmative defense.†           Under the first rule, the junior doctor may not be held liable solely on the ground that he did not consult the surgeon who performed the operation on Jason, his skill or competence being presumed.  But assuming it is proved that the jolting in the ambulance did not contribute to or cause the paralysis but only the antibiotics treatment,   the legal task of proving negligence on the part of the junior doctor would still be an uphill battle.  The defendant would enjoy the presumptions under the first and fourth rule: he is presumed competent, and is likewise presumed as not negligent.  On the other hand, Jason would have to prove that his administering antibiotics to Jason despite his being intoxicated with alcohol is contrary to or deviates from the standard of good medical practice in the community. In Boyce v Brown (1938), the issue was whether the taking of an x-ray of the plaintiff’s fractured ankle was considered standard practice (it was not).   Such question regarding standard practice may only be resolved by the testimony of experts in the medical field.  Thus, Jason and company must present affirmative evidence of negligence, such as the failure of the junior doctor to comply with the recognized or standard procedures in such cases, resulting in the injury.           As regards the nurse who administered the anti-tetanus injection, the above rules would likewise have to be applied. If it is considered standard procedure in hospitals or in the medical community to test a patient for allergy before being given a drug which may have fatal effects in case a patient is allergic thereto, her failure to observe or comply with the said standard resulting in injury to Penny, in addition to the other elements stated above, would make her presumptively liable for malpractice.  The nurse may contend in her defense that the allergy test is not standard or customary practice (if such is indeed the case), and that this rule (otherwise known as the locality rule) should not be applied anymore by the courts owing to the growing variance in the knowledge and skill of physicians throughout the country and the world.            If the evidence would warrant a finding of liability due to negligence on the part of the nurse, I would advise my client to implead the attending physician who had given the order to the nurse, as well as the hospital on the ground of respondeat superior.            Suppose Jason proves his case against Alice, a question arises as to what extent she would be liable for damages in view of the fact that the injuries suffered by Jason may have been aggravated by the ambulance crash. In such case, the damages shall be apportioned on the basis of the liability of the parties responsible for the first and the second accident. The Colorado Court of Appeals, deciding Bruckman v Pena (1971) cited â€Å"the general rule that one injured by the negligence of another is entitled to recover the damages proximately caused by the act of the tort-feasor, and the burden of proof is upon the plaintiff to establish that the damages he seeks were proximately caused by the negligence of the defendant.†           Subject to the above qualifications and views, Jason, Penny and Fancy Fashions Ltd. may file the appropriate action for damages which will be determined by the evidence presented in court. Such awards may include but are not limited to medical expenses, the loss of earnings as a result of injury or incapacity, and moral damages due to the pain and suffering caused by the defendants’ tortious acts or omissions.            Finally, I would advise Jason, Penny and Fancy Fashion, Ltd. that despite the wealth of jurisprudence on tort cases, there is no clear-cut approach to a particular case, and the outcome of the cases they would file in court would depend most entirely on the evidence they would present during trial, and how the trier of fact would evaluate them.

The History of Fermentation Essays -- Fermenting Wine Distillery Alcoh
The History of Fermentation It is impossible to set a date as to the first time fermentation was performed. It is possible, however, to guess, and this guess is roughly 8,000 years ago. Wine has been written about for centuries, in the Greek and Roman myths and scriptures. The Greek god of wine, Dionysius, was in charge of the fermentation atop Mount Olympus. The people of this time may not have known exactly what they were doing, but it was a somewhat complicated procedure. The crushing of grapes, and the storing of their juices led to an amazing beverage that is still used in current society. This process of fermentation was used throughout the time of early Christianity, and other religions, for purposes within sermons. Throughout the Renaissance, fermentation was used in the making of wine as well as bread, not to mention new medical applications. Fermented products were brought to America along with the new settlers. With new government, though, America was put into a prohibition, which did not last long. Today, fermentation processes are carried out nearly perfectly, without too large of variations among the products. Although fermentation has been known of for at least 8,000 years, in 1865 Louis Pasteur was the scientist who really discovered the process of fermentation. At this time, Pastuer was the Dean and professor of chemistry at the Faculty of Sciences in Lille, France. He was originally asked by a friend to investigate difficulties he was having manufacturing alcohol by the fermentation of beetroot. Often, instead of alcohol, the fermentations were resulting in lactic acid. At that time, fermentation leading to the production of wine, beer, and vinegar was believed to be a simple and straightforward breakdown of sugar to the desired molecules. It was believed that the chemical breakdown of sugar into alcohol during the fermentation of wine and beer was due to the presence of inherent unstabilizing vibrations. Yeast cells were found in the fermenting vats of wine and were known as living organisms, yet they were only believed to be either a product of fermentation or catalytic ingredients t hat provided useful ingredients for fermentation to proceed. The brewers of wine, beer, and vinegar were having horrible times with quality control. Yields of alcohol might suddenly fall off; wine might unexpectedly grow ropy or sour or turn to vinegar;... ...s that the fermentation leading to the creation of ethanol has made billions and billions of dollars in profit, along with giving millions of people jobs. It is amazing that something that has had such a large impact on the world (as the fermentation of ethanol has) begins on the molecular level. Bibliography 1.

Spartan Heat Exchangers Inc.
Current State Spartan Heat Exchangers Inc. is a leading designer and manufacturer of specialized industrial heat transfer equipment for more than 10 years. The company’s primary products are transformer coolers, hydro generator coolers, air-cooled heat exchangers and transformer oil coolers. Their USP – Fin tube type heat exchangers and long lasting products. They are into highly customized heat equipments & because of new competition from European & Korean companies they have changed their corporate policy, which emphasize on reducing the product variety & standardized the product. The new business policy also states of reducing the current lead time from 14 weeks to 6 weeks. Problem Statement The Materials Department headed by Rick Coyne has to take a lot of initiatives internally to incorporate various implications of the new strategy, and submit his report to his boss Max Brisco of the changes suggested by him within a week. His major challenges are: †¢Change from responsive to anticipatory model. †¢Keep-up with the increased competition in the industry. Inventory turns from present 4 times to 20 times. †¢Eliminate material shortages & stock outs. †¢Reduce cost of Purchase goods by 10%. †¢Reduction in the custom lead time from 14 weeks to 6 weeks. Analysis of Key issues & options: †¢Interpretation of new corporate strategy. (ok, might need some rephrasing of words) In our view the key issue is to find out how to adapt the supply chain strategy from a responsive model to an anticipatory model. The previous corporate strategy was based on customization of each of their products which is now being changed to standardization. This change can be best illustrated by comparison of figures 1. 1 and 1. 2 in Appendix 1, wherein the possible corporate structures may tend to three different values, i. e. cost, differentiation and responsiveness; Spartan strategy has shifted from a focus in differentiation and responsiveness to a cost and responsiveness value proposition. †¢Job shop method of production to Hybrid. The new corporate strategy implies re-engineering from a job shop method of production (which involved manufacturing operations with several departments, each of which produced particular components, Ref Case) to a hybrid method of production which is a flow operation, where multiple work stations can be working simultaneously, which will mainly allow Spartan to increase volume of production, reduce lead time, it will further lead in cutting down the carrying cost of inventory, even though the inventory will be high. Raw materials procurement The customization strategy required the presence of many vendors and a high level of inventory in the warehouse. On the contrast, the new corporate strategy reduces variety to 3-4 basic lines for each product category will require less variety of raw material but in higher quantity. This will give the company a higher negotiation power for better overall conditions, including delivery time, transportation cost, price, quality & budget. †¢Le ad time reduction from 16 to 4 weeks One of the main concerns for the company is to reduce the lead time from 16 to 4 weeks in order to keep up with the competition in the market. This should be discussed with the vendors at the time of negotiation & should also be a clause in the PO. Now since the process is already standardized, Rick should also insist on improved communication between sales, materials department & vendors will help in the prediction of demand. There is also an option of keeping a buffer stock in case of an inconsistent demand. We believe that this goal can be achieved with an adequate supply chain strategy. The fact that we are reducing the number of vendors required will allow us to be more selective and procure only from the vendors that provide a service in accordance with our new needs, i. e. only from those who in the past have consistently delivered in few days lead time or those who can commit to do so in the future. †¢Change in Corporate Culture The new strategy will affect the corporate structure in the company. Earlier the work was based on the specific requirements of the client and it was more of research based but now the focus on research will be less and it will be more on general requirements. Therefore the type of work would shift. The present organizational chart of the SC Department in the company includes two buyers, one material control clerk, one expeditor and two shipper/receivers. This structure was functional to the previous strategy because there was a strong focus on the purchasing function. We believe that in order to maximize the SC Department resources in accordance with the new structure the positions and functions of the people with the SC Department will have to be adapted to strengthen the inventory management function of the company. There company could benefit from having one person responsible for forecasting demand. Processes should be reviewed to ensure that the SC Department has sufficient access to information in order to achieve this task. Re-buying will also be of utmost importance now in order to ensure that there is always sufficient inventory to maintain production going. †¢Vendor Development. A vendor base of 350 can prove very beneficial for Spartan. Such a large base of vendor proves that Spartan has a good market reputation. Also the increase in the requirement of raw material & its variety getting reduced will help Rick to: †¢Maintain & improve quality †¢Find & develop best–in-class supplier (both these points will help in superior quality product) †¢Standardize the items bought & the processes used to procure them (now possible due to standardization of product) (Ref pg 48) †¢Purchase required items & services at lowest cost of ownership. †¢Another option that Rick will have is Consignment buying (Ref. Pg 35) (which is possible due to the space available in the warehouse since the variety of raw materials has reduced) This space can be used to keep suppliers inventory under his control (specially for Aluminum which constitutes 40% of the total inventory). A)This will help Rick in another way as he will be able to solve the problem of stock out, specially for the basic raw material ie Aluminum. B)Since Spartan will now need only a fixed variety of raw materials, hence the requirement of a large vendor base will not be required. This will also provide Rick more negotiation power for a ixed vendor base, for his basic raw material as explained later on. The new business strategy being formulated for 5 years will give more negotiation power in view of a commitment of a long term relationship. As we previously mentioned, the new strategy of Spartan will enable the Supply Chain Department to restructure the procurement scenario. As we know, purchasing and supply management are critical to the success of a company. The general modern conception regarding procurement is recognizing the importance that, in addition to price, other elements may have in this relation. In this line of thought, we believe that being able to reduce significantly the number of vendors will allow the company to make some considerable advances on vendor development. Since there will be a less variety of raw materials to purchase and in a larger quantity than previously, due to the new anticipatory approach, the company should aim to establish long term relationship with these fewer vendors. However by no means do we want to imply that purchasing function at Spartan should be any less strategic. We believe that this should continue, but also that some resources can now afford, and will highly benefit, from reallocating some resources to the inventory management function. Spartan will require more inventory and raw materials as it would be an ongoing production always. For that the company will have to get in touch with their suppliers more often in order to fulfill production requirement. Suppliers will also have a strong incentive to cooperate with the company as they can obtain higher revenues due to more bulk orders. Additionally, we know that reducing the costs will drive profitability up. Moreover, reducing the purchasing price on raw materials will produce a leverage effect on the return on assets. This means that any given reduction that Spartan can obtain on the procurement price of aluminum will translate in an even higher increase in the return on assets. (DEMONSTRATE) A reduction in the prices from suppliers is one aspect that is always possible and in this case is necessary because of the situation that is happening in the market. Spartan should keep always in mind that many of their customers (including some of the key ones) decided to opt for standard product design because it brings them more advantages like lower cost and faster delivery. In consequence, Spartan should look for new suppliers that satisfy effectively the new needs of that the market is asking for. A 10% of reduction in the prices from suppliers could be possible by searching new suppliers that offer standardized products of good quality. It could be a good idea to search new Asian and European suppliers because they are being very competitive according the new market standards. Spartan should also consider finding an effective logistics route which allows them to reduce costs and they should consider the possibility of consolidating their goods. This will represent a decrease in the expenses that the company has to pay once they receive their goods. †¢Training of manpower The change in corporate strategy will require the employees to get training in accordance with the new product line. The anticipated increase in business will require more staff so the HR Dept will have to recruit more staff. †¢R&D : New initiative for a array of new Products The R&D will have to redirect their efforts to more standardized manufacturing process for a new product line based on the new strategy. †¢Procurement of Extra Machinery (don’t think this is necessary) Key Assumptions †¢The materials requirement in a customized product setup is not predictable, but the raw material requirement is quiet predictable in the standardized product setup which will help in reduction of a variety of raw material. We assume that there will be an on-going production. †¢Another part of the corporate strategy is to reduce the lead time from 16 weeks to 4 weeks. By adoption of this strategy Spartan will now be able to overcome one of its weakness, which will result in increase in sales, since Spartan will now have access to customers, it lost due to longer lead times. This increase in sales will provide high inventory turnover and help Rick to negotiate the prices & increase his inventory turnover from 4 to 20 times. Inventory Turnover = Sales/ Inventory (ref Pg. ___) †¢ The transition from customization to specialization will also help in reduction in the raw materials variety, which will provide some extra space in the companies’ warehouse, which will allow Rick to do â€Å"Consignment uying†(ref pg 35). Key Results of Calculations: Total cost of Inventory (Raw material & WIP) = $3,500,000. 00 Out of which 40% is Raw Material = $ 1,400,000. 00 Remaining 60% is WIP = $ 2,100,000. 00 Target 10% Reduction in cost of raw materials = $ 140,000. 00 †¢35% of the cost of raw material is Aluminum = $ 490,000. 00 A 15% reduc tion in the cost a saving of $ 73,500. 00 (as suggested this is achieved by consignment buying or bulk buying & savings on transportation). †¢Out of the remaining inventory cost of $ 910,000. 00 A 7. % reduction on cost price (ie a saving of $ 66,500. 00) on the remaining inventory achieved through negotiation & PO’s (which will fix the prices for over 12 months) will allow Rick to achieve the target. †¢Since in customized WIP is more which will decrease in standardization, ie reduction in handling & storage cost. No commitment but looks achievable over a period of 12 months. Recommendations: Based on the above argument we believe that the positivity in Rick’s mind in supporting the new corporate policy is valid & achievable. Appendix 1 1. 1 1. 2 1. 2

Inclusion Equal Opportunities And Diversity Education Essay Essay
In 21st century classrooms, there are more and more children coming from much more diverse backgrounds. Teachers need to teach these children with effective teaching methods and must therefore have pedagogical approaches that deepen their cultural understanding. Many of these children have a range of ability in language, abilities and culture. Centre for Studies on Inclusive Education (CSIE) stated that teachers must employ not only theoretically sounds but also culturally responsive pedagogy. Teachers must create a classroom culture where all children, regardless of their cultural or linguistic backgrounds are welcomed and supported and provided with the best learning opportunity. What is inclusion? Inclusive education is concerning equality and human rights. Inclusion is more than an understanding and a policy requirement. It is on the subject of respect and values which welcomes diversity in the classroom and a wider part of society. The inclusion statement n the National Curriculum (DfEE/QCA 1999) stated that differentiation from a wide variety of needs and the planning of lessons to ensure access and participation was part of normal teaching. This point was further emphasised by Overall & Sangster (2007) saying that it is about meeting the different needs of as many children as possible in mainstream schooling. What are equal opportunities? Equal opportunities are about being inclusive and fair in the way you deal with all children. Treating all children the same is not enough. Overall & Sangster (2007) define fair to be when the teacher meets the needs of every child as far as they can. What is diversity? Diversity is something that is becoming more and more popular in the classroom. In simple terms, diversity just means that are is a variety of different types of children in the classroom. Not only is it a professional standard to develop an understanding of the cultural diversity in their class but it is also a legal requirement (Children Act, 1989, 2004), but are these legal requirements being met? Are these evident in schools? Figures from the Department for Children, Schools and Families show that last year saw the biggest year-on-year increase in pupils from ethnic minorities. Across the country, they accounted for almost 22% in 2007 compared to 20. 6% in 2006. From these figures it is clear to see that inclusion, equal opportunities and diversity are part of the ‘norm’ classroom and need to be therefore addressed appropriately. I will now discuss what it means for a school to be inclusive and if a school is ‘effective’ does it mean that it has to be inclusive as well? I will also look at barriers to learning and how they are overcome. School Inclusion It is important for schools to be inclusive. Hayes (2004) believes that inclusion is best understood as an aim, aspiration or even a philosophy, rather than as a set of techniques that can be applied to a situation. It is important for a school to aim to be inclusive to everyone in the school, whether this is towards children, teachers or other members of staff. Inclusion tends to be regarded as ‘the right thing to do’ and it is this moral imperative than often makes teachers feel guilty about saying anything negative about inclusive policies and practices. It is important to remember that a positive attitude to inclusion has an impact on the process of developing inclusive teaching strategies (Halliwell, 2003). As a trainee teacher, it is important for me to understand that inclusion is a process that is influenced by a number of different factors and has a different meaning for everyone involved. From experience, I have seen inclusion being carried out. This occurred during assembly when the whole school came together for their Friday ‘celebration assembly’. During this assembly, birthdays were announced and the children came to the front. All teachers and children joined in with singing happy birthday while as the same time signing it. This was a lovely experience to observe. The school as a whole were including everyone. Although there are many different indicators of inclusion to reflect on such as policies, practises and experiences of individuals learning, it is also my aim to carry these out. Such policies include Inclusive Schooling (DfES 2001b). This document provides practical advice to schools and LEA’s on the inclusion framework and sets out seven principles of an inclusive education service. The Every Child Matters Policy (DfES 2003, 2004a, 2004b) has according to Arthur, Grainger and Wray (2006) ‘served to set educational inclusion within the broader context of radical change in the whole system of children’s services including explicitly shifting from intervention to prevention with services working together more effectively’. The overall aim of Every Child Matters is to reduce the number of children who experience educational failure, engage in offending or antisocial behaviour, suffer from ill health or become teenage parents (DfES 2003). The Every Child Matters aims are said to be at the heart of Children Act 2004 (Arthur, Grainger and Wray 2006). Finally, according to Overall and Sangster (2007) the idea of an inclusive school is one that will meet the needs of many pupils in a variety of ways; within special classes, through support for individuals, differentiation in the curriculum and carefully thought through teaching, is an exciting idea. This is something that I should really develop as part of my philosophy of inclusive education. Barriers Inclusion is about looking for ways of reducing the barriers to learning that may exist for children who present more challenging circumstances. Prejudice and stereotyping are often significant in creating and maintaining these barriers (Overall and Sangster 2007). Within The National Curriculum (DfEE/QCA 1999) three principles were set out to develop a more inclusive education. Within these principles, the third is to ‘overcome potential barriers to learning and assessment for individuals and group of pupils’. These groups of pupils can range from SEN to EAL to Gifted and Talented. Overcoming barriers is further emphasised in Inclusive Schooling (DfES 2001b) with one of the principles stating ‘schools, local education authorities and others should actively seek to remove barriers to learning and participation’. Overcoming potential barriers to learning and assessment is relevant to all children who have already been identified to have an emotional, mental or physical need. Teachers must plan to meet these needs and also the needs of the rest of the class at the same time. One method of doing this is to pair a pupil with EAL with a pupil who is good at English. Peer encouragement is a great way of encouraging talk. I witnessed an example with an emotionally vulnerable child. This particular child was getting frustrated and upset when they couldn’t do their times tables because other pupils around the table were counting aloud and therefore interfering with this pupil’s train of thought. To resolve this problem, the pupil was sent into a quieter room where there was full concentration of the subject. As a trainee teacher, I need to plan my lessons which overcome barriers which I may face in delivering a lesson or scheme of work. Conclusion Schools should all have an inclusion, equal opportunities and diversity policy in place and one that is being actively carried out by all pupils and members of staff. It is important that I am positive about the right for all children to be valued and to receive the best education available for them. This can be helped by implementing and receiving guidance from local education authorities or attending extra training days. From reading I have learnt to develop my own pedagogy with regard to inclusion, equal opportunities and diversity. As a training professional I have a unique opportunity to contribute to developing my own personal practice and help with developing policies with other colleagues. My aim now is to need all the needs of the children who I will be teaching both on placement now and in the future with my own class of children.

NEW EYE TRACKING TECHNIQUES IMPROVE REALISM OF AIR Essays (484 words)
NEW EYE TRACKING TECHNIQUES IMPROVE REALISM OF AIR Essays (484 words) NEW EYE TRACKING TECHNIQUES IMPROVE REALISM OF AIRCRAFT SIMULATORS A simulated flight environment for pilot training may soon be made more realistic through the use of eye-tracking technology developed by researchers at the University of Toronto's Institute of Biomedical Engineering (IMBE). Many safety and cost benefits are obtained by training aircraft pilots under simulated conditions, but to be effective the simulation must be convicingly realistic. At present, th e training facilities use large domes and gimballed projectors, or an array of video screens, to display computer-generated images. But these installations are very expensive and image resolution is low. Further, it would take an enormous amount of addi to improve image quality significantly throughout the whole viewed scene. However, based on the visual properties of the eye, realism can be obtained by providing a high-resolution 'area of interest' insert within a large, low-resolution field of view. If the image-generating computer 'knows' where the pilot's fixation is, it mage there. The technology to make this possible was developed by a research team headed by Professor Richard Frecker and Professor Moshe Eizenman. The work was carried out in collaboration with CAE Electronics Ltd. of Montreal with financial support from the Natural Sciences and Engineering Research Council of Canada. Their eye-tracker can record and analyze accurately up to 500 eye positions per second. The system works by means of capturing and processing the reflections of a low-level beam o f invisible infra-red light shone onto the eye. Multi-element arrays capture the image of the eye and digitize the information, which is then processed in real time by a fast, dedicated signal processing unit. The difference in position between the ligh tre of the pupil reveals the instantaneous direction of gaze. Developments by the IBME team have significantly increased the speed of signal processing in addition to enhancing accuracy of eye position estimates. Eizenman believes that "these improvements make our eye-tracker very effective in monitoring the large G-force environment where the pilot tends to make larger eye movements because of contraints which exist on movements of his head". In a new generation of aircraft simulators, under development by CAE Electronics Ltd. of Montreal, a head tracker which tells the direction of the pilot's head is mounted on top of the helmet. The eye tracker is mounted on the front of the helmet, and is ll exactly where the pilot's eye is fixating. Frecker said that "successful integration of our eye tracker into the novel helmet-mounted CAE flight simulator would result in a new generation of simulators that would likely replace the current large domes and cumbersome video display units." Initial tests of the integrated system will be carried out in collaboration with CAE Electronics at Williams Air Force Base in Arizona later this year.

How to get a job without applying for it
How to get a job without applying for it What could be better than getting a new job with minimal effort on your part? Yes, it sounds impossible, but you can land a great new job without ever having to apply for it. Sure, the typical path to the next job in your career journey often requires some hard work and dedicated job hunting- searching out open positions that fit your skill set and requirements, leveraging your network to uncover opportunities, carefully crafting targeted cover letters and resumes, diligently completing applications and sending out emails, interviewing, following up, and waiting- and most of us have gone through this process several times. However, there is an alternate path, and it’s usually a much more direct and easier one to your next job. According to a recent Business Insider article, those who possess an array of valuable and marketable skills that their respective industries prize will have companies and recruiters seeking them out, regardless of whether or not they’re seeking a new job. It pays to at least be open minded when this happens: â€Å"In today’s economic environment, people with valuable skills in leadership roles are likely to be receiving more and more calls from recruiters. You never know if the opportunity that will be presented will be more attractive than your current role. And, you can gain a boost of 15 percent or more in your compensation by being willing to make a change, likely far outpacing the raise you can expect in your current role.†It’s true- even if you’re not looking for a new job, with the right mix of experience and skills you just might be a passive job candidate- an attribute prized by recruiters- without even knowing it.According to Business Insider, recruiters seek out people who are open to new opportunities but not actively seeking them. The logic is that if someone is a talented candidate and is currently unemployed or is actively seeking out a job while currently employed, the re might be some sort of issue. Of course, this isn’t always the case, but it’s an assumption recruiters can often make. On the other hand, even if there isn’t an issue, chances are that the well-qualified person is applying to many companies at once. Recruiters don’t want to waste time courting someone who can easily decide to take an offer from another company.However, if recruiters seek out candidates who aren’t actively looking, those risk elements disappear.It’s clear that being a passive candidate can open up a world of new professional opportunities to you. So how can you become one? Business Insider offers up some ideas about how you can do to help subtly set yourself up as a passive candidate in your field.Recognize and build key skills.The key to becoming a prized passive candidate is to possess the skills in your field that companies are eager to have on their teams. Learn what skills leaders in your industry possess and what comp anies are looking for, and then make sure your skill set fits the bill.Join appropriate professional organizations.Most professions have industry recognized associations and organizations, and it’s in your best interest to become a member of as many as possible. Not only will it help you build your network and provide an array of social opportunities, it can also get you on the radars of recruiters when they’re looking to source talent. Make an effort to get involved and attend events whenever possible.Don’t neglect social media.The truth is, many recruiters scour social media when on the hunt for passive candidates. They’re looking for industry leaders, mavericks, and disrupters whose social media pages reflect their passion, dedication, and accomplishments. If you want to be viewed as a viable passive candidate, make sure your social media brands you as a serious professional with plenty to offer potential employers.Join LinkedIn groups.Building on the two previous tips, make sure you take full advantage of professional groups on LinkedIn. It is among the most widely used sites by recruiters looking for passive candidates, and for many of them, their first stop just might be looking at members of professional groups in their respective fields. If you’re not using LinkedIn to its fullest potential, you just might be doing yourself and your career a disservice.  Keep your certifications, skills, and awards up to date.This advice is not only good for growth in your current job, it’ll help impress and attract recruiters. The more distinctions and honors you have under your belt, the more desirable you’ll be.Here’s the bottom line- if you want to have a future where potential jobs come looking for you, and not vice versa, you should work to set yourself up as a valuable passive candidate. Use the strategies and advice provided here and you’ll be on your way to making future job hunts much easier!

Community Health & Social Care Essay Example | Topics and Well Written Essays - 2000 words - 1
Community Health & Social Care - Essay Example This research highlights obesity is a medical condition that arises as a result of an excess of body fat. Obesity is determined using the body mass index (BMI), which is derived using a person’s weight in kilograms divided by height in meters squared. A person is overweight when the BMI is greater than 25 while obesity is a BMI value of 30 and over. Obesity reduces the quality of a person’s life and makes a person vulnerable to a lot of serious medical complications. Persons suffering from obesity are highly vulnerable to medical complications such as osteoarthritis, high blood pressure, diabetes, heart diseases and certain cancers. With such medical complications within a society, health facilities experience a serious strain as well as high mortality rates.From this essay it is clear that the World Health Organisation points out that the number of people who are obese is higher than the number of overweight people across the world. Drastic change in lifestyle is the main contributing factor to this phenomenon, where many people have tuned to sedentary lifestyles. This lifestyle does not demand a lot physically. In today’s modern world, majority of people are using personal cars, washing machines, lifts and computers, making them less physically active most of the time. Leisure times such as watching TV while eating foods that have high calorie levels increases further a person’s risk of being obese.
