Encephalitis Is An Infection Of The Brain Biology Essay

Encephalitis Is An Infection Of The Brain Biology Essay Encephalitis is an infection of the brain that cause of irritation and inflammation to the brain Medical Encylopedia, 2012. Primary encephalitis is happened when the infection of the brain or spinal cord. Secondary encephalitis is happened when the infection is started to spread to the whole body and to the brain (Nordqvist, 2009). Encephalitis is a swelling of the brain parenchyma (nervous tissue in brain) that responsible for function of electrochemical communication and the ability of body to send message to different parts (david) http://www.doereport.com/imagescooked/4049W.jpg Goodman (2003) argued that encephalitis is an acute inflammatory disease of the parenchyma of the brain. It is caused by direct viral invasion or hypersensitivity initiated by a virus. Encephalitis is characterized by inflammation primarily in the gray matter of the central nervous system (CNS). Neuronal death can result in edema. There can be damage to the vascular system and inflammation of the arachnoid and pia matter. 1.1.1 Encephalitis http://findlaw.doereport.com/imagescooked/4047W.jpg Debbie Bridges (2012) argue that encephalitis is a swelling of the brain tissue, it will become serious when it can cause change personality, debility and another symptoms with the different part of brain affected. It usually happened to children and elder with low immune system. It is very rare, in U.S, about one in 200,000 people in year. Nordqvist (2009) agreed that encephalitis is acute inflammation of the brain because immune system of the body is too low to attacks viral infection. Fever and headache usually the first symptoms and it become more dangerous like unconsciousness, confusion and coma. The patient will be faced a problem such as behaviour changes, loss of memory, language and speech problem (aphasia) and epilepsy. Arthropod à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ borne (mosquito à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬ borne) viruses and herpes simplex (herpes simplex type 1) are the most common that causes encephalitis. Encephalitis is an acute febrile disease usually of viral origin and involves with nervous system (). 1.1.2 Viral Meningoencephalitis According to kumar 2004, viral encephalitis is infection of the brain at parenchymal almost constantly associated with meningoencephalitis (meningeal inflammation) and sometimes with encephalomyelitis (involves spinal cord). 1.2 Anatomy of brain http://healthy-lifestyle.most-effective-solution.com/wp-content/uploads/2010/09/human-anatomy-brain.jpg Figure Anatomy of the brain http://antranik.org/wp-content/uploads/2011/11/dura-mater-superior-sagittal-sinus-subdural-space-subarachnoid-space-falx-cerebri-periosteal-meningeal-arachnoid-villus.jpg Figure Layer of meninges The brain is protected by the scalp, the skull and the meninges, cerebrospinal fluid and blood-brain barrier. The structures of brain consists cerebellum, cerebrum, brainstem and pituitary gland. Layer of meninges include the dura mater (strongest layer), arachnoid mater) and pia mater (nearest to the brain). (Stephen n all 2010). Antranik (2011) states that meninges are surround the brain and protect the brain itself. The function meninges is cover and protect the blood vessel that supply at brain and contains cerebrospinal fluid (CSF) between the pia mater and arachnoid mater. Dura mater consists periosteal and meningeal at immediately deep to the poriosteum. Tortora (2009) notes that the function of the blood- brain barrier (BBB) is to protect the brain from harmful substances and pathogens by prevent it enter brain through blood. The function of CSF is protecting the brain and spinal cord from chemical and physical injury. The cerebrum is the largest part of the brain. Each area of cerebrum is the most important function for example controls movement and languages. The function of cerebellum is control coordination and movement. Function of brainstem is control involuntary functions such as blood pressure, temperature and breathing movement. The structure that controls of the endocrine gland is pituitary gland (Stephen 2010) 1.3 Type of Encephalitis Western equine encephalitis is arboviral infection that spread by mosquitoes which more occur in summer and most common in young children. St. Louis encephalitis is more usually at United States and affected older person. It is more seriously than younger person. West Nile fever is a form of encephalitis that caused by falvivirus, spread by mosquitoes with certain birds as an intermediate host. Encephalitis has spread from northeastern United States. Neuroborreliosis (lyme disease) is due by a spirochete, transmitted by tick bites in summer season. The part of the tick bite is red with a pale center and gradually increasing size. Herpes simplex encephalitis is arising from spread of herpes simplex virus type 1 from the trigeminal nerve ganglion. It is occurs occasionally and dangerous. This encephalitis can cause extensive necrosis and haemorrhage in the brain and usually involves the frontal and temporal lobes figures .. http://neuropathology-web.org/chapter5/images5/5-hsvl.jpg Figure heamorrhagic necrosis of the temporal and frontal lobe in adult Herpes Simplex Virus encephalitis. CHAPTER TWO LITERATURE REVIEW 2.1 Causes encephalitis Figure 2 a herpes simplex virus the most common cause encephalitis. Viral infection is the cause that affects the encephalitis. Encephalitis may be cause with different type of viruses. Herpes simplex virus is the main cause of severe cases in all ages including newborns. The person will get this virus from an infected person through breathing in respiratory droplets and skin contact. It can also through by insect bites like a mosquito and contaminated food or drink. Arbovirus encephalitis is a viral encephalitis that carried by insect (mosquito and ticks). It is rare condition where severe case more likely is happened to young children and elderly. Picture of Culex mosquito laying eggs Figure Culex mosquito laying eggs Picture of arbovirus transmission cycle It also may cause by a vaccine such as rubella, mumps and measles (Kathryn Sue 1994). Adenovirus, coxsackievirus. Eastern Equine Encephalitis Virus and Echovirus are also associated with encephalitis. A number of viruses for which there is now a vaccine may also cause encephalitis. These include meales, mumps, polio, rabies, rubella, varicella (chickenpox). Other causes of encephalitis may be occurring by an allergic reaction to vaccinations, autoimmune disease, bacteria (lyme disease and tuberculosis) and the effects of cancer. According to (Christian Nordiqst ) the causes of encephalitis can be category by two which are primary (infectious) encephalitis and secondary (post infectious) encephalitis. For primary encephalitis, there are three main categories of viruses which are common viruses (herpes simplex virus) , childhood viruses (measles ,mumps), and arboviruses. Secondary encephalitis can be caused by a complication of viral infection. 2.2 Incidence 2.2.1 Incidence Encephalitis in Malaysia In September 1998, an epidemic of severe fever encephalitis among pig farmers was first reported in the state of Perak Malaysia that was associated with high rate mortality. At first death were thought by Japanese encephalitis (JE) that is endemic in Malaysia and occur occasionally. However, characteristic of JE is different to these cases. A few cases patients were young children and most of the cases happened to men that have worked with pigs. Whereas, JE is mosquito borne that most common among young children and has no associated with particular occupation. JE was eliminated from possibility JE was the cause due to illness and deaths among infected pigs. By February 1999, similar disease were happened in pigs and humans in other area in Malaysia. 2.2.2 Incidence Encephalitis in Overseas Different viruses will occur in different locations. Many cases will tend to cluster in a certain season. According to Kathryn Sue (1994) the arthropod à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬borne occurs in epidemics with different incidence like as geographic and seasonal incidence (table). Eastern equine encephalitis is the least common of encephalitis but is the most serious encephalitis. table Viral encephalitis Type Geographic incidence Seasonal incidence Arthropod- borne : Eastern equine encephalitis Eastern United States Autumn Western equine encephalitis Uniform distribution, throughout the United States Summer and early fall St. Louis encephalitis Widespread distribution , in the far west occur in rural area, elsewhere in urban areas Late summer Venezuelan equine encephalitis Sourthwestern united States Year round California virus encephalitis Midwestern states Early fall Herpes simplex encephalitis No particular geographic distribution No seasonal incidence Poliovirus poliomyelitis Sporadic distribution where nonimmunized persons cluster Summer and ealy fall Rabies Sporadic distribution throughout the United States Bites more common in the late spring and throughout the early fall DISEASE GEOGRAPHIC LOCATION VECTOR/ HOSTS Herpes encephalitis United states / the world Human to human contact West Nile encephalitis Africa, West Asia, Middle East, United States Mosquito / mostly birds Eastern equine encephalitis East Coast (from Massachussetts to Florida), Gulf Coast Mosquito / birds Western equine encephalitis Western United States and Canada Mosquito / birds Venezuelan equine encephalitis Western Hemisphere Mosquito / rodents La Crosse encephalitis United States (Midwestern Southeastern) Mosquito / chipmunks, squirrels St. Louis encephalitis Milwestern mid- Atlantic United States Mosquito/ birds Japanese encephalitis Temperate Asia, southern and southeastern Asia Mosquito/ birds and pigs Picture of worldwide distribution of major arboviral encephalitides Figure worldwide distribution and arbovirus transmission cycle. 2.3 Mortality/morbidity Encephalitis may be a mild infectious disease to a severe disorder that is life-threatening. The dramatic clinical manifestations of encephalitis are fever delirium or confusion progressing to unconsciousness, seizure activity cranial nerve palsies, paresis and paralysis, involuntary movement and abnormal reflexes. Signs of marked intracranial pressure may be present, 2.3.1 Mortality Charles Patrick 2012 argued that the certain of patients with encephalitis the death rate can be high. The death rates of St. Louis encephalitis can up to 30% of the cases. For Japanese encephalitis, the range death rate is from 0.3% to 60% of the people infected usually within the first week of illness and herpes encephalitis, 50%-755 of people die within 18 months. In contrast, it can increase survival up 90% when treatment by acyclovir (Zovirax). 2.3.2 Morbidity According to james nina 2004. Survival rates are due to the etiology of the disease. In some cases it can be fatal. In USA, according to Centers for Disease Controls and Prevention), encephalitis most occur in children, elderly people and individuals have weakened immune systems approximately in 0.5 in every 100,000 individuals. Besides that, in UK the National Health Service (NHS) places a figure at 1.5 cases per 100,000 people. ( Christian Nordqist 2009) 2.4 Signs and Symptoms 2.4.1 Symptoms of Encephalitis Before encephalitis begins, some patients will feel cold or stomach infection. For the case of encephalitis is not very severe, the symptoms may be similar with other disease such as fever (not very high), mild headache, low energy and poor appetite. For other symptom is confusion, drowsiness, light sensitivity, vomiting, irritability or poor temper control. (encephalitis , 2012) According to Christian norqist 2009, symptom for less common severe in encephalitis is the patients will experience stiff neck and back (occasionally). There also can be stiffness of the limbs, slow movement and clumsiness. The patient will also have cough and feels drowsy. For the more severe cases, the patients experience severe headaches, nausea, vomiting, confusion, memory loss, hearing problems, hallucination, seizures and possibly coma. The patient will be become aggressive for some cases. (christain norqist 2009). Symptoms of encephalitis in infants and newborns may be difficult to recognize. The parent or guardian should be alert of baby crying more than often (there will become worse when the baby is picked up and comforted). Besides that, the parent should be look out of vomiting, soft spot on the top of the head (frontal) may bulge out more. Other symptoms are includes body stiffness and poor feeding. (christain norqist 2009). For emergency symptoms in encephalitis is the patients will loss of consciousness, poor responsiveness, coma, muscle weakness, seizures, severe headache, and sudden change in mental functions which are amnesia, lack of mood, impaired of judgement inability to make decision and less interest in daily activities. (encephalitis 2012) 2.4.2 Signs of Encephalitis Signs of encephalitis may be show muscle weakness, speech problem, skin rash, mouth ulcers, mental confusion and neck stiffness. Other than that, signs of encephalitis are abnormal reflexes and increased intracranial pressure. Table Summary of symptoms Symptoms of encephalitis Less severe More severe In newborn and young infants Mild headache Fever Poor appetite Light sensitivity Vomiting Disorientation Stiff neck and back Severe headache Nausea Vomiting Confusion Memory loss Speech problem Hallucination Seizures coma body stiffness poor feeding Bulging soft spots on the top head table Summary signs of encephalitis Signs of encephalitis Muscle weakness Mouth ulcers Neck stiffness Skin rash Speech problem Abnormal reflexes Increased intracranial pressure Mental confusion 2.5 Pathophysiology The virus causes inflammation of brain tissue. The brain tissue swells (cerebral edema), which may destroy nerve cells, cause bleeding in the brain (intracerebral haemorrhage), and brain damage. When the virus spread by haematogenous (via bloodstream) like example rabies virus, it replicates outside the CNS and enter in the CNS. Since the virus through the blood- brain barrier t virus enter neural cells. These will result disruption of cell functioning, perivascular congestion, haemorrhage and a diffuse inflammatory response that disproportionately affects gray matters over white matter. Certain virus depend to neuron cell membrane preceptors that only found in specific parts of the brain like example Herpes Simplex Virus (HSV) more likely causes haemorrhage necrotic encephalitis with predilection for the limbic system, inferior and medial temporal lobes. (David) According to james nina 2004, individuals who obtain encephalitis more frequently develop permanent neurologic disabilities. This condition is more serious than meningitis. This is happened when the viral infection produce in cerebral edema with numerous hemorrhagic spots scattered throughout the cerebral hemispheres, brainstem and cerebellum. 2.6 Histopathology 2.6.1 Arthropod- Borne Viral Encephalitis CHAPTER THREE IMAGING MODALITIES 3.1 Computer Tomography (CT scan) Computer Tomography is the combination of computer technology and x-rays as a result two dimensional images of organ, bones and tissues. To detect sign of encephalitis or inflammation of the meninges, usually procedure with contrast is required. The contrast is injected into bloodstream to more differentiate tissues in the brain. (national institude of neurological disorder and stroke 2011) Mahesh (2011) states that in adult, encephalitis in CT scans visualize hypodensity in the temporal lobe either bilaterally or unilaterally. It also involves with or without frontal lobe. 3.2 Magnetic Resonance imaging (MRI) MRI is use strong magnet and computer- generates radio waves to produce more detail images of body structures which are tissues, bones, organs and nerves. MRI is better than CT scan which is give more clearly picture that can help to recognize brain and spinal cord inflammation. Infection, tumors, eye disease and blood vessel irregularities that can be stroke. The images that require more detail, a contrast may be injected. (national institude of neurological disorder and stroke 2011) 3.3 Electroencephalography (EEG) EEG is use by monitoring electrical activity in the brain through the skull to detect abnormal brain waves. The function of EEG is to help diagnose certain seizure disorder, specific viral infection, for example herpes virus and inflammation of the brain or spinal cord. (national institude of neurological disorder and stroke 2011) 3.4 Ultrasonography Mahesh (2011) states that the role of ultrasonography in detects herpes encephalitis are limited. This is because it limited to identify the periventicular destructive process in neonatal evaluation ultrasonogaphy. Ultrasound showing a good near field but less far field resolution (Cranial Ultrsonography in Neonates 2010) . According to (james nina , 2004) MRI is precious diagnosis because it can detect brain inflammation earlier than Computed tomography (CT), ultrasound, nuclear medicine studies, or EEG evaluation. Other anomalies such as a brain abscess or subdural emphysema or hematoma that mimics the clinical sign of viral encephalitis can be rule out by MR. 3.5 Nuclear Imaging CHAPTER FOUR IMAGES OF FEATURES OF PATHOLOGY 4.1 Computed Tomography (CT Scan) http://www.mypacs.net/repos/mpv3_repo/viz/full/0/38/120/39969726.jpghttp://www.mypacs.net/repos/mpv3_repo/viz/full/0/38/120/39969721.jpg Figure shows 30 years old men that have AIDS, presenting with left facial palsy.

It performed with phased array transducer. It is shows mildly dilated frontal horns and bilateral grade 1 intraventricular hemorrhage (arrows). CHAPTER FIVE DISCUSSION 5.1 Difference Encephalitis and Meningitis Encephalitis is the dangerous than meningitis because the person that has encephalitis is more develop to permanent neurologic disabilities. According to james nina 2004, meningitis is an inflammation of the meningeal that covering the brain and spinal cord. Bacteria, viruses or other organisms that reach the meninges are the causes of meningitis. This can be happened in elsewhere in the body by blood or lymph as a result from trauma and penetrating wounds, or from adjacent structures that become infected. Most common that cause meningitis is bacterial infection. Kathryn sue 1994 states that meningitis is infection of meninges that causes by bacteria, viruses, fungi, parasites and other toxins. This infection can be classified to acute, subacute and chronic. The pathophysiology, treatment and clinical manifestation are different for each type of organism. Bacterial meningitis is a primary of an infection of the pia mater and arachnoid, the subarachnoid space, the ventricular system and the CFS (kathyn sue 1994). The types of bacteria that carry for acute bacterial meningitis are meningococci, streptococci, and pneumocci. Middle ear or frontal sinus is responsible that carried the bacteria to meninges. The most common meningitis in children is meningococcal, the most common meningitis in adult is pneumococcal and streptococcal meningitis is the most common in young children. CHAPTER SIX TREATMENT 6.1 Treatment The objective of treatment is to help the human body to fight the infection and relieve symptoms with give supportive care like example rest, nutrition, and fluids. Antibiotics will give to patients if the infection is caused by bacteria (certain bacteria) and antiviral medication (acyclovir and foscarnet) to treat herpes encephalitis or the severe viral infection. Anti seizure medication ( phenytoin) will be given to prevent seizures. (encephalitis 2012) Mayo 2011 states that treatment for mild cases include bed rest, drinking plenty of fluid and anti- inflammatory drugs such as acetaminophen to relieve fever and headache. For more severe cases of encephalitis can be category into three treatment which are Antiviral drugs, supportive care and follow up therapy. 6.1.1 Antiviral drugs Acylovir and Ganciclovir are antiviral drugs that common used to treat encephalitis but it is not responding for some viruses such as insect-borne viruses. This drug also can be very effective to treat herpes simplex virus. Nausea, vomiting, diarrhea, pain of muscle or joint and loss of appetite are the side effect for the antiviral drugs. Abnormalities in kidney or liver function are rare serious problem (Mayo 2011) 6.1.2 Supportive Care For severe encephalitis, additional supportive care also be needed in the hospital. This is including breathing assistance as monitor heart function and breathing, intravenous fluids is to ensure that appropriate levels of essential minerals and proper hydration. Anti- inflammatory also be given to help reduce pressure and swelling within the skull such as corticosteroids. Patient that have seizures or to prevent seizure, anticonvulsant medicine such as phenytoin is given (Mayo 2011). 6.1.3 Follow up therapy Follow up therapy is depending to the type or severity of complication. This therapy includes physical therapy which is to help improve flexibility, strength, motor coordination and balance. Occupational therapy is to use adaptive products that help with everyday activities and develop everyday skills. Patient that have speech problem, speech therapy can be help to relearn muscle control and coordination. Psychotherapy is learning how to be coping strategies and have new behavioural skills that can improve personality changes and mood disorder (Mayo 2011). 6.2 Diagnosis According to National Institute of Neurological disorders and stroke (2011), the doctor may diagnostic tests to confirm the presence of inflammation and infection by following a physical exam and medical history to looking activities of the past several days such as patient have bite by animal or insects or any contact with ill persons. The patients may perform a neurological examination, laboratory screening of blood, urine and body sections and analysis of the cerebrospinal fluid. A neurological examination is to assess nerve function, coordination and balance, mental status, changes in behaviour and function of motor and sensory. Usually, the doctor use small light, reflex hammer to test of strength and sensation or nervous system. Laboratory screening of blood, urine and body secretions is use to determine the presence of antibodies and foreign body that can detect and recognize brain and spinal cord inflammation and infection. Analysis of cerebrospinal fluid is the procedure that known as lumbar puncture. The procedure of lumbar puncture is special needle is inserted into the lower back and then a small of amount of cerebrospinal fluids is removed. CHAPTER SEVEN PROGNOSIS 7.1 Expectations Usually, outcome of encephalitis is depend on what infection involves, the severity of illness, how quickly time treatment is given. Patient with very mild encephalitis most of them can make a full recovery, although the process treatment may be slow. The patient can be recovering in 2-4 weeks for patient have experience only fever, body stiffness and headache. For the severe cases, the patient may be have problem with hearing, speech, blindness, behaviour changes, seizures, memory loss, muscle weakness, and cognitive disabilities. Long-term therapy, medication and supportive care may be required for these patients. (national institude of neurological disorder and stroke 2011) Goodman (2003) notes that patient who may have been ill at the onset , their rate recovery range from 10% to 50%. The patients have mumps meningoencephalitis and Venezuelan equine encephalitis have an excellent expectation. Other encephalitis that have moderate to good rate of survival are western equine, St. Louis and California encephalitis. Herpes simplex encephalitis has a moderately good outcome, 50% of person neurologic disorder and 20% mortality. With similar infections, young children more take longer recover than adults. In infants, permanent cerebral sequelae are occurred. 7.2 Prevention Christian Nordqist (2009) found that the effectives way to reduced risk to get encephalitis by keeping up to date with vaccines. Other than that, take measures to reduce the risk being bitten in area to have mosquito that carry virus encephalitis. For example, keep house mosquito free, wearing appropriate clothing, do not go mosquito infested area, using insect repellent, avoid go outside at specific time where there a lot of mosquito, for example at night and make sure there are no stagnant water in house. Beside that, encephalitis can be prevented by avoid sharing food, glasses or other object that have be exposed from infected person. Good personal hygiene also can reduce risk to get disease from infected person. Wash hand frequently with soap and rinse under running water ( National Institude of Neurologic Disorder and Stroke 2011). CHAPTER EIGHT CONCLUSION

Internet Censorship Essay - America Needs Censorship of Cyberspace

America Needs Censorship of Cyberspace      Ã‚  Ã‚   In June of 1998 the country was horrified to learn of the death of James Byrd Jr. He was a 49-year-old black man who had been found horribly mutilated after being dragged to death. Authorities have charged three men with murder and violation of civil rights ("A Fatal Ride in the Night" 33). Obviously, if convicted, these men are guilty of a horrible crime, but what if this crime had been committed after viewing a racist website? If a person reads an emotionally charged, hate-filled website and then commits an act of violence, can the creator and owner of the website also be found guilty?    No laws have yet been established to censor material in cyberspace. The Communications Decency Amendment, which sought to ban pornography and other offensive material on the web, was struck down in Congress last year. The Internet has exploded in the past decade. It is everywhere and millions of people have access to it, through work, school, and home. As the Internet becomes a part of daily life for more and more people, laws need to be made to banning pornographic, racist, and other offending websites, to protect citizens from the threats these websites pose. Although some may see this as an infringement of their First Amendment rights, it is important for us as a society to reject these ideas and ban these websites.    Many lawmakers want to establish laws to control what is available on the Internet. Their number one reason is the availability of everything on the Internet to children. Even though parental controls, software that blocks offensive sites to children, are available many parents fail to use them. Senator J. James Exon, who proposed the amendme... ...Victor J. Vitanza.

This proposal presents my research on the above topic. We will look into how HR managers can optimize a organization and also the turnover rate of the employment in the airline is generally high for cabin crews and staff retention is always a issue that arise in many companies in different nature of business and sometimes it is not only the wages that created such problem. Basically, I have structured the proposal into three different sections, for easier understanding and be organised. Don’t waste time! Our writers will create an original "The Efficiency Oriented People" essay for you Create order Firstly, in the Literature Review section, it will explain on the theory of optimization of the organisation and staff retention, which includes memorable quotation, diagrams and striking examples. Secondly, in the Research methodology section, it will focus on type and nature of the research, description study, the choice of research instrument and the research limitations will be included. Thirdly, in the Presentation and Discussion section, it will analyse the data that is gathered earlier and present my analysis result by showing the relationship with observed facts and also the key problems that Singapore airline faces. 2.0 LITERATURE REVIEW It presents a summary of the academic literature on my chosen topic and serves to inform my research. It also develops my knowledge of chosen topic and helps me understand the organisation and topic better. 2.1 Optimization Premji (2006) define Optimization As the utilizing of organization resources well, at high efficiency and enables the organization to achieve the desired end results. This can be define as achieving or getting the full use of utilization efficiency and the effectiveness. (Premji, 2006) Above is the diagram which shows the relationship of the efficiency, utilization and effectiveness as mention earlier. From the diagram, we can understand that the change of any one of the factor the other factor may be changes as well. This means that for us to understand the performance of the organisation , we must have views in different aspects as all the factors are linked. For example, if utilization is very low, then both efficiency and effectiveness will not achieve any results therefore there will be no benefits that can be obtained from it. Very often, if the organization goals for the result is being achieved, it will tend to overlook the importance of the other factors. Organiza tion should not overlook the factors so as to better prepare themselves to achieve the future results. 2.1 Efficiency According to Premji (2006), Efficiency is defined as how well are you using what you are using. It is also known as the ratio of output and input. (Premji, 2006) This diagram shows the process of the input which resulted in output at the end of it. Usually in an organization, employee can be classified into three main groups: Output oriented people Input oriented people Efficiency oriented people 2.1.1 Output Oriented People Output oriented people are people who try all ways or anything that allows them to get the end results that they desired. These people try to get the most out of the output and using any ways they can to the input and process. It is necessary to understand that the output is actually different from the end results. Therefore, with maximize output does not necessary achieve good results. Generally the output oriented people will use more than what the cost should be to obtain a good result, however they will not notice it. As HR manager, he/she have to ensure that the organisation resources are fully utilized and should try not to employ output oriented people or creating such people in the organization. 2.1.2 Input Oriented People Input oriented people are known as workaholics. They generally focus on the input and the efforts, they believe by creating more input it will lead to a good output. Success to them are enjoying their work and work as hard as they could to achieve the desire output. As HR manager, he / she should recruit a fair percentage of these people, as they are able to perform the instructions given to them due to their working attitude. 2.1.2 Efficiency Oriented People Efficiency oriented people are people who believe in a return after the investment. Generally, they focus in make full use of the efficiency either to obtain a high output for a certain amount of input given or less to achieve a equivalent of output. As HR manager, who ensures that organization resources are being utilized, should try to hire and groom a larger percentage of efficiency-oriented employee in the organization. With the combination of input-oriented and efficiency oriented people, the organization performance is achievable. 2.2 Utilization Premji (2006) will define Utilization as the measure of how much are you using out of what you have. This means that one should put in whatever you have and not to miss out any opportunities. Utilization and Efficiency are closely linked and aid each other. For example in a case whereby there is a need for a reduction of input, and due to the increased in effieciency, the extra input can be used in somewhere else, due to utilization. The relationship between Utilization and Efficiency can affect an organisation performance. If organisations focus on Efficiency orientation without utilization focus, it will lead to apply efforts that give good returns. On the other hand, if organisations maintain Utilization focus without Efficiency orientation, will lead to using all available resources, without achieving adequate returns. 2.3 Effectiveness An organizations capability to achieve the wanted end result is known as Effectiveness. This may be related to profits, expansion, customer satisfaction, branding and many more. In an organisation, teams often set a results as their goals. (Premji, 2006) From the above diagram, visualizing the three factors that work on different purposes: Utilization deal with resources and efforts Efficiency concerned with quantity and quality output Effectiveness is all about desired results Utilization and Efficiency are the internal aspects of an organization, Effectiveness brings in the customers view and gives an external aspect to the Optimization. Effectiveness is related to the what the organization wants to achieve. For example, if organizations aspirations are low, end results can be easily be achieved, therefore effectiveness can be high. Premji (2006:9) mention that Effectiveness in an organization is all about knitting together the individual components with the strategy to achieve the end result. But there are two important criteria to be considered: Individual components must be good. Components must be knitted well together. The diagram below will show a better idea of knitting together: (Premji, 2006) Coverage of Effectiveness Efficiency UtilizationWith higher effectiveness, it does not only helps to achieve the expected results but also reduce the required output from carious processes, to achieve the same expected end results. On another hand, Hayes (2010) view effectiveness from a different aspect, he defined it as: Purpose: Profits are usually used to measure the organization effectiveness but not to all the organisation. For instance the government hospital, the effectiveness of hospitals will be on the waiting time and services provided and not the profits out of it. Hence, as manger, is required to identify the main performance indicators that reflect the purpose of the organization. Stakeholder pers pective: Different stakeholder uses different indicators to judge an organizations effectiveness. From their point of views, profits may be their main concern or rather the most important factor, but from the wider community of view, such as customer, employee and supplier, they are affected by products and services produced. Every individual have different views. The failure to manage the organization key stakeholders perception, it may threaten the organization . Level of assessment: By only focusing on the overall performance may resulted in inefficiencies being detected. Effectiveness can be assessed at different levels, such as the organization level, department level and individual. Alignment: Assessment of effectiveness need to be associated across the organization. At this point, it will be good to differentiate between effectiveness and efficiency, for better understanding all the factors, Carnall (2003) defines efficiency as achieving stated goals within given res ources constraints. And the definition of effectiveness includes the good use of resources to achieve goals but also the need to adapt to changing in order to remain efficiency . 2.4 Optimized Organization Peter F. Drucker (1993) defines business as: Business is a process which converts a resource, distinct knowledge into a contribution of economic value in the market place. As mention earlier on, Optimization is high Utilization, high Efficiency and high Effectiveness. The table below shows the nine possible combinations of Utilization, Efficiency and Effectiveness on a two point of scale high and low: Utilization Efficiency Effectiveness Conclusion Low Low Low Something fundamentally wrong. Low Low High Organization not ambitious enough Low High Low Resources idling Low High High Excess capacity High Low Low Lot of wastage High Low High Can reduce resources High High Low Weak knitting together High High High Optimized Organization (Premji, 2006) In conclusion of the table, it is insufficient to just work on one factor and the factors were not handle properly, it may lead to a reduction of optimization. All three factors should be maximises as a practice rather than as a reaction to a problem. 2.5 Staff retention Jennifer A Carsen (2005) defines retention as how many of your current employees stick around over a given period of time. However, retention may not always be a good thing for the organization this is so as retention may include poor performers, unhappy staff who may have been stuck in the job due to finances. Retention is all about retaining the good staff in the organisation. Retention may also weeding out of poor performers and keeping space for the better ones. 2.6 Workplace diversity Jennifer A Carsen (2005) , As the workforce continues to diversify, organisation must take equal employment opportunity so as to stay competitive. Organisation should not only employ staff of different race, culture, gender, age, sex but also to understand the ways that they can respect the staff values, expectations and capabilities. According to Jennifer A Carsen (2005) there are five reasons why the staff choose to leave the organisation: Staff are given no compelling reasons to stay : They do not feel a sense of belonging towards the organisation that they are in. Career limiting stereotypes : Some staff may feel that they are incompetent or not qualified , they feel the pressure of proving their competencies even when they have good performance in their job scope this therefore limit their career path as whatever they do do not seem to be the best to the organisation and they feel that it is hard for them to move forward. Poor supervision : Many superiors do not know how to handle their staff. The way superiors handle staff and solving problems do have a great impact to the staff too. For instance, if the staff felt that the superiors did not handle the problems fairly they may then choose to quit their job. Unclear and misaligned career path : Staff is unclear or unsure about their career path and when they do not know who in the organisation owns the career planning process. Safe assignments, unclear goals: Staff were not given with challenging projects. They are also concern about the unclear or shifting jobs performance criteria. 2.6 Instilling diversity principles In order to achieve staff retention, the organisation should implement the principles provided by Jennifer A Carsen (2005). Obtain commitment at the top : This is to achieve responsibility to all the levels especially the management so as to bring the implementation a success. Hold management accountable: Performance reviews and incentives award should be done by the management. Managers should treat all staff with respect and dignity. Reward those who embody the workforce diversity principles : Do not reward those who have failed to carry out the principles. Reward should be done fairly. Encourage employee participation : With the management alone to carry out the principles is not enough. Organisation should also encourage their staff to voice out and also allow them to play a part in implementing the principles. 3.0 Research Methodology A questionnaire (See appendix 1) is conducted for data collection. It involved around 100 cabin crews therefore the total collections of the questionnaire were 100 copies. Generally the questionnaires were conducted through a number of ways. Firstly, the questionnaires are distributed out through email or hard-copy to the cabin crews with the help of a friend who is also a cabin crew of SIA. Secondly, carrying out observation on the daily activities taking place in the airport whereby the cabin crews are always around there, and with a small discussion group (3-5 people). Lastly, arranging a short interview session with the various seniority of crews, these enhance the value of information that I have gathered as important information such as organizations optimization, retention and the ways these crews work. 3.1 Description Study Description Study act as a guide to the researchers in obtaining the data during the data collection : Contacting friend who for help, a covering letter with a summary of the study aim with a request of the interviewee requirement was send out via email. Getting the interviewee detail with a follow up phone call in which the researchers should explain the aim with more information and answer to any queries. Prepared for the Questionnaire and start sending it out through via email or hard-copy to all the interviewees who has responded . A letter of appreciation was send out to all the interviewees and follow up with the due date indicated. Do a follow up action by contacting all the interviewees if it is necessary for more enquires. For instance, a incomplete questionnaire. Sending questionnaire one more time to the interviewee who have yet to respond. Researcher shall make use of both personal and friendship circles when looking for participants who are either working at HR departments or those who have recruiting experience. The researcher would have to speak to the HR department , any of the representatives to see whether if they would like to participate or interested in the project as mentioned to them. With the contact details provided by the personal or friendship circles, the researcher may email or sent to the respondent to form a small group to observe the daily routine of their work or operation. With addition, a interview session will also be conducted with selected interviewees, mainly with people of different seniority, to enhance the value of the information which had been gathered through the questionnaire and the discussion group. The interview session is conducted based on 4 level of cabin crews within SIA, from flight stewardess, leading stewardess, chief stewardess and in-flight supervisor. In conclusion, the research sample includes 4 representatives from the cabin crew line.To maintain anonymity, personal details of t he interviewees have not been mentioned. 3.2 Research Rational Questionnaire (See Appendix 1) was being selected for my research because it is very cost saving and efficient as compare to other approach of the data gathering. And also this approach allows the interviewees to complete the questionnaire during their free time and they may feel more comfortable to give the answer of what they really felt as this questionnaire is anonymity. Interviewees are required to complete a self administered questionnaire, with 75% questions based on a 5 point scale is used to measure the variables. The constructs are measured based on the multi-items scales (MIS) rather than single item scales (SIS), as MIS allows the answer to be more specific to be averaged out when combined. According to Anderson and Narus (1990), to increase the response ratethe questionnaire should be send out twice. The interviewees will be given a due date of two wweks after the questionnaire had been send out. If no response was done after one week questionnaire will be send out for the second time. 3.3 Research Limitation The limitation of using questionnaire is expected as follows: Slow- Feedback: the interviewees do not respond or submit the questionnaire before the due date. Generally, take a longer time. Below Expected Result: Send out to 100 cabin crews, expected to receive 90% 100% but only received 50% responses. Incomplete Questionnaire Form Gathered: Some of the questionnaire is not completed especially under personal particular section and Question 4, about 40 % of the respondents leave it blank or place NIL Difficulty in Gathering Questionnaire result: Gathering of the results may be hard as the questionnaire are either send back via email or manually therefore a manual entry is require to sort or gather the data obtain. 4.0 Presentation and Discussion In this section, I will look into the optimization and also staff retention as mention in the previous sections. Both optimization and staff retention plays a important role to bring in the success of the organisation. William Bridges (1995) stated that There is no generally agreed-upon way to inventory an organizations culture nor is there any shortage of theorists and consultancies that have developed ways of mapping key elements from many different perspectives The data which had been collected can assist the managers understand the certain barriers and how to improve in the organisation. 4.1 Analysing Singapore Airline (SIA) Very often due to the complexity of the organization, most of the organization tends to forget about the importance of optimizing and staff retention. According to the report of my questionnaire, only about 30 percent of respondents indicated that they pay attention of optimizing and the staff retention as a ongoing basis. Majority of the respondents feels that the organisation only look into ways of optimizing and retain staff in the case when crisis happen. The questionnaire also shows that respondents view of staff retention as a general managerial tool (60 percent), for targeting major change initiatives (20 percent), as development opportunity (10 percent) and for building organizational strength (10 percent). Most importantly, optimizing a organisation and staff retention allows managers to gain knowledge into how employees view the organization to how they like the organisations. Another reason why many organizations tend not to pay attention is that the organisation may not have a idea or knowledge of it. In the questionnaire, respondents were split over the question of managements response of staff retention issue. With a result of majority (55 percent) felt that senior management tend to take changing issue seriously and the rest of the respondent (45 percent) state the reverse Managers may fear of changes is because they are worried that with changes the staff may raise a higher expectations and this may lead to work difference. Lastly, optimizing and staff retention is very important as it is the key to success or the organisation. 4.2 Assessing Singapore Airline ( SIA) alignment One of the key objective of optimizing and culture change is to test the degree of alignment. For instance if the organisation is not contributing to to high performance practices then there is a need for change to allow a closer alignment. In general , alignment is usually difficult to achieve and the closing up of the alignment gap may become a problem towards high performance. The common obstacles to high performance evident in my questionnaire finding include: Lack of Share Values: The strategy is not clear and even when a strategy is set it is not being practised, unsuitable management pattern and the lack of openness to take in new changes. Lack of Leadership: Did not take the need of the staff seriously , stopping the politics and conflict and did not address on the issue of workload. Lack of Mentorship: Do not have time to coach and develop the staff, shortage of skills, heavy workloads and high stress. Inappropriate Systems: The rewards given is inappropriat e, the meetings are poorly run and it beats the purpose of having one. 4.3 Assessing Singapore Airline (SIA) performance In order to achieve high performance it involves the Achieving high performance involves in a connection between employee and the organization. As we all know, employee wants to feel that they are being valued by the organisation by their good performance and to be fairly accessed. Managers can play a role by influencing on every individual performance by giving the need and support to assist the staff to do a good job, especially those with experienced. 4.3.1 Level of Accountability Generally, the common problem that SIA face is when the the staff do not have a clear idea whether the work had been done to avoid overlapping. This in return cause a double work. To ensure a correct level of accountability the staff will require to have a correct information to allow them to know what is being required. To ensure the increase of accountability of SIA, it will require looking into: Job explanation Clarify everyday jobs Manage Performance Use progress reviews. Impose sanctions if necessary 4.3.2 Rewards System It is very important in conveying the organizational values: Performance benchmark Performance expectations Rewards have two organizational objectives: To recognise past performance To motivate people to perform The most important factor is that the staff have to feel that the reward is being carried out fairly. Reasonable salary is the most basic to create a trust, as each individual do not want to feel that they are actually being underpaid. 5.0 Conclusion Through this research project, it allows me to find some useful data in which allows me to know what to do to retain a staff and also introduce to me the idea of optimizing the organisation and i realise the main concern is how to increase performance of the organization. In this research, staff retention is a key issue to performance success as it will optimize the organization to achieve higher operation, competence and success in return achieving a better or improving the performance of the organisation. In conclusion, there is no two similar organisation which is the same and develop the same solution for staff retention and in optimizing the organisation to achieve the high performance and success, it is usually situational. There is many challengers and pressure from both internal and external environment, and so a constant change is always required to catch up with the changing environment. Organizations should look into how the business can be competitive to other organi sation and should provide a learning experience to the staff and growth as well so as to create a greater staff engagement. When these staff obtain a higher ski , the chances of getting a higher performance is greater and easier. All organisation should be flexible. However the flexibility will depend on the organisations ability to digest the information and be decisive in the decision being made. Lastly, the road to success of the organisation will depend on the people willingness to adapt to the new changes and so it is important for the organisation to know exactly what is the need of their employees need.
