Parkinsons Disease essays

Parkinsons Disease essays Parkinsons disease usually affects people of late middle age. Most run between the age of 50-60. The symptoms of Parkinsons disease are usually subtle and occur gradually. Some examples of symptoms a person may have, are feeling shaky or having trouble getting up from a chair or a couch. Others may notice that their speaking is softer or quieter. They will lose track of a thought or feel irritable or even depressed for no reason. These are early symptoms that may last a long time before the more classic and obvious symptoms appear. For now there is no way to cure or prevent Parkinsons disease from happening., but there has been new research looking at (PET) Position Emission Topography. This will allow scientists to scan the brain, which see chemical change that occurs in the brain. Using PET scientists can study the brains nerve cells that are affected by disease. IF you are in the major stages of Parkinsons disease the major symptoms are tremors, problems walking, bradykinesia, and rigidity. Rigidity is an increase of stiffness in the muscles. If it is eased by medications, rigidity is always present. Its also responsible for a mask like expression. In some patients it leads to sensations of pain in the arms and shoulders. Secondly, victims with experience bradykinesia, which means slowness of movement. It causes the brains to react slower in its transmission of instructions to parts of the body therefore causing the body to act slowly in carrying them out. Poor balance is often true when victims move abruptly. Some patients experience falls due to poor balance. Last are tremors, they will affect three out of four patients. Tremors may affect only one part or side of the body. For the most part they dont disable people and it disappears during sleep. Some minor symptoms are depression, emotional changes, me ...

Trash Islands - the Ocean Garbage Patch

Trash Islands - the Ocean Garbage Patch As our global population expands, so does the amount of trash we produce, and a large portion of that trash then ends up in the worlds oceans. Due to oceanic currents, much of the trash is carried to areas where the currents meet. These collections of trash have recently been referred to as marine trash islands. The Great Pacific Garbage Patch The Great Pacific Garbage Patchsometimes called the Eastern Garbage Patchis an area with an intense concentration of marine trash located between Hawaii and California. The exact size of the patch is unknown, however, because it is constantly growing. The patch developed in this area because of the North Pacific Subtropical Gyre- one of many oceanic gyres caused by a convergence of ocean currents and wind. As the currents meet, the earth’s Coriolis Effect (the deflection of moving objects caused by the Earth’s rotation) causes the water to slowly rotate, creating a funnel for anything in the water. Because this is a subtropical gyre in the northern hemisphere it rotates clockwise. It’s also a high-pressure zone with hot equatorial air and comprises much of the area known as the horse latitudes. Due to the tendency of items to collect in oceanic gyres, the existence of a garbage patch was predicted in 1988 by the National Oceanic and Atmospheric Association (NOAA) after years of monitoring the amount of trash being dumped into the worlds oceans. The patch was not officially discovered until 1997, though, because of its remote location and harsh conditions for navigation. That year, Captain Charles Moore passed through the area after competing in a sailing race and discovered debris floating over the entire area he was crossing. Atlantic and Other Oceanic Trash Islands Though the Great Pacific Garbage Patch is the most widely publicized of the so-called trash islands, the Atlantic Ocean has one as well in the Sargasso Sea. The Sargasso Sea is located in the North Atlantic Ocean between 70 and 40 degrees west longitude and 25 and 35 degrees north latitude. It is bounded by the Gulf Stream, the North Atlantic Current, the Canary Current, and the North Atlantic Equatorial current. Like the currents carrying trash into the Great Pacific Garbage Patch, these four currents carry a portion of the worlds trash to the middle of the Sargasso Sea where it becomes trapped. In addition to the Great Pacific Garbage Patch and the Sargasso Sea, there are five other major tropical oceanic gyres in the worldall with conditions similar to those found in these first two. Components of Trash Islands After studying the trash found in the Great Pacific Garbage Patch, Moore learned that 90% of the trash found there was plastic. His research groupas well as NOAAhas studied the Sargasso Sea and other patches around the world and their studies in those locations have had the same findings. It is estimated that 80% of the plastic in the ocean comes from land sources while 20% comes from ships at sea. The plastics in the patches consist of items like water bottles, cups, bottle caps, plastic bags, and fish netting. It’s not just  large plastic items that make up the trash islands, however. In his studies, Moore found that the majority of the plastic in the worlds oceans is made up of billions of pounds of raw plastic pellets called nurdles. These pellets are a byproduct of plastics manufacturing. It is significant that most of the trash is plastic because it does not break down easilyespecially in water. When plastic is on land, it is more easily heated and breaks down faster. In the ocean, the plastic is cooled by the water and becomes coated with algae which shield it from sunlight. Because of these factors, the plastic in the world’s oceans will last well into the future. Garbage Islands Impacts on Wildlife The presence of the plastic in these patches is having a significant impact on wildlife in a number of ways. Whales, seabirds, and other animals can easily be snared in the nylon  nets and six-pack rings prevalent in the garbage patches. They are also in danger of choking on things like balloons, straws, and sandwich wrap. Additionally, fish, seabirds, jellyfish, and oceanic filter feeders easily mistake brightly colored plastic pellets for fish eggs and krill. Research has shown that over time, the plastic pellets can concentrate toxins which are passed on to sea animals when they eat them. This could poison them or cause genetic problems. Once the toxins are concentrated in the tissue of one animal, they can magnify across the food chain similar to the pesticide DDT. Finally, the floating trash can also aid in the spread of species to new habitats. Take, for instance, a type of barnacle. It can attach to a floating plastic bottle, grow, and move to an area where it is not naturally found. The arrival of the new barnacle could then possibly cause problems for the areas native species. The Future for the Trash Islands Research conducted by Moore, NOAA, and other agencies show that  trash islands are continuing to grow. Attempts have been made to clean them up but there is simply too much material over too large of an area to make any significant impact. Some of the best ways to aid in the cleanup of these islands are to suppress their growth by enacting stronger recycling and disposal policies, cleaning up the worlds beaches, and reducing the amount of trash going into the worlds oceans.

Remote Access Attacks Case Study Example | Topics and Well Written Essays - 1250 words

Remote Access Attacks - Case Study Example The other assumption would be the network was setup by a rookie as the topology is poor and vulnerable to attacks. Finally the final assumption would be the management is not aware of the need of a secure network. The management needs to be informed and enlightened on information confidentiality, integrity and availability (Lammle, 2008). Firstly the network is vulnerable as the firewall doesn’t serve its purpose. Firewall is meant to barricade the traffic between a public and private network. In our case the public network is the internet and the private network is the Quick Finance Network. It uses access lists and other methods to ensure the security of the private network. From the diagram the firewalls should be deployed between the router and the internet, and the web server and the internet and between the internet and the VPN server. Access lists that are employed on the firewall are set of conditions kept by routers that determines allowed traffic to and from various services on the network. In the quick finance network access lists can be deployed in the network to control the movement of traffic between the different buildings and also in a building, in case of information applying to specific offices/departments. Access lists are helpful in exercising control over network traffic. Access lists offer network control. These lists enhance the flexibility to filter the packets that flow in or out router interfaces. The access lists help protect expanding network resources without impeding the flow of legitimate communication. They differentiate packet traffic into categories that permit or deny other features. Proxy is another security measure that can be deployed. Proxy restricts who accesses what and which sites to block. The layer design deployed also needs to be improved. The network needs to be created using the proposed three layer design. The proposed three layer design comprises of core layer- this is where the public and private networks meet through a firewall router/switch, distribution layer – this layer holds switches which lead to different buildings and offices and access layer – the layer where the user is connected to the network. Vulnerabilities on this network There lots of vulnerabilities on this network and lots of access points where intruders can gain entry of this network. For starters the firewall has been wrongly placed. The firewall should be put across the perimeter of the network in order to limit access to the network. From the topology the firewalls don’t serve their purpose as they have been put beside the servers. The firewall is used for basic packet filtering. The filtering decision is made separately for every packet, thus a packet that was allowed earlier won’t dictate the entry of a later packet. It’s based on source and destination IP address, protocol and source and destination port numbers. The network should use the proposed layer 3 network model. Where we have three layers: access layer, distribution layer and core layer. This will avoid a bad topology as the current one where all the machines are connected via an Ethernet cable. With a layer three topology it would implement use of switches and more routers to control movement of packets and enforce access control. It would also have all the servers well placed in order to ensure data security, availability, integrity and confidentiality

Assessment, Management and Reduction of Falls in the Older person Essay

Assessment, Management and Reduction of Falls in the Older person - Essay Example This concept indicates a factual phenomenon that the life span of people aged 60 and above has steadily increased in the past half century. There are over 600 million in 2000; 1.2 billion in 2025 and 2 billion in 2050 (WHO). This phenomenon has created a huge sector in the society, which is comprised by people from age 60 and above. The occurrence of this size of a population of people who are 60 and above is unheard of, throughout recorded history because certain conditions meant that people normally and generally lived only until an average of thirty-five. However, with the advancement of medical technology the increasing number of people who survive to above 60 years old is a commonality (WHO 1999). Moreover, the ageing population phenomenon is a global concern (WHO). This means that almost all countries across the globe except for some countries in Africa are experiencing the dramatic increased of an ageing population (WHO). In this regard, looking into the conditions and concerns of the elderly members of the society has become one of the major interests of both the government, especially policy makers, and some non-governmental organizations (WHO). As governments respond to the phenomenon of ageing population, one concern that has become dominant in their sector is the problem of the results of a fall. This is due to the fact that one of the major causes for morbidity within the elderly population is a fall. Every year, oe third of those over the age of 65 experience a fall with an increase in incidences occurring with the increase in age. More than 50% of women who are over the age of 85 experience a fall within a year. (Pearse 2004: 478). Furthermore, injuries resulting into fall are not only a major cause of death among the elderly but that it â€Å"imposes an enormous public health burden world-wide† (Devroey et al 2002: 113). As well, the issues with falls is a concern where costs of the results of the fall impact the health care

Prison and National Probation Service cooperation Essay

Prison and National Probation Service cooperation - Essay Example While some perceived of it as a constructive step toward the reduction of reoffending rates and a positive contribution towards the greater national aim of crime reduction, others critiqued it as a misinformed strategy which would confuse the boundaries between prison' and community.' Such confusion, as critics maintain, will have dire societal consequences insofar as it is predicated on the assumption that inmate and out-mate offender management subscribe to the same concern, principles, aims and, thus, paradigms (Valios, 2004; Palmer, 2003; Peters, LeVasseur and Chandler, 2004). Proceeding from the background and controversy outlined in the above, the dissertation shall focus on the aims of the proposed justice system reform, critically analysing Noms from the perspective of best practices managerial theories. The rationale for selection did not simply emanate from the contemporaneous nature of the issue, or solely from its societal value but because the researcher has been professionally involved in both prison and probation services for a number of years and is, consequently, in a position to analyse Noms and argue the exigencies of its implementation on the basis of experiential evidence. Apart from the experiential knowledge and both subjective and professional interest in the issue, the topic was further selected consequent to the fact that the researcher's professional background places him in a position whereby he can collect primary data, conduct the requisite surveys and administer the necessary questionnaires with comparative ease. In other words, the researcher's professional background and awareness of the fact that community safety and societal interests are best served through the articulation and implementation of an effective and...As earlier stated, the primary areas of co ncern are the National Offender Management Service and organisational and people management theory. As pertains to either of these two issues, the existent wealth of academic literature testifies to their respective values and the extent to which the latter may be constructively informed by the former. Over the past two decades, offender management literature has articulated the imperatives of utilising existent people and organisational management tools and strategies in order to attain the managerial efficiency and effectiveness level upon which the goals of the justice system are predicated. The justice system, operating according to the principles of offender exclusion and rehabilitation within a prison system, followed by the release of offenders into society and under the supervisory guidance of the probation service, has been largely incapable of satisfying the justice system’s expressed goal of reducing overall offence rates and eliminating reoffending. The persistent inability to satisfy the articulated goals exposes what some have identified as a fundamentally flawed people and organisational management paradigm. According to the aforementioned perspective, the failure of the justice system to either reduce crime rates or rehabilitate offenders, thereby offsetting reoffense potentialities, is indicative of the greater failure to embrace effective and efficient people and organisational management paradigms.

Health and Socail P1 Essay Example for Free

Health and Socail P1 Essay P1 Explain potential hazards and the harm that may arise from each in a health or social care setting Relating to the physical environment The physical environment is everything that is around you, this includes; 1. The building 2. The air 3. The temperature 4. Objects 5. People 6. Pets The physical environment has a huge impact on the staffs and individuals well-being. The spread of Airborne infections are increased when the ventilation is poor, airborne infections such as colds and influenza, so it is important to have fresh air circulating at all times in a health and social care setting, especially in elderly homes as older people tend to catch things more easily as do younger children. Individuals should never be in a draught and should always be warm enough. Older people, babies and people with disabilities find it harder to keep their body at an adequate temperature; you should always cater to their needs. Fumes and smoke shouldn’t contaminate the air that should be clean. The ventilation should remove stale air and provide air movement. All the rooms in the environment should have central heating; each should be able to be controlled to the specific temperature the individual wants. The lighting in each room should be bright enough and in a position for the individuals in the environment to read and participate in other activities. Emergency lighting should also be in place in case a light breaks or electrical problems occur; it should come on if there is a power failure. When the lighting is poor is can cause numerous problems and is hazardous to those who are in that setting, it will affect those with a vision impairment, with people that have limited vision you should make sure that they are in a well-lit area. Equipment Hazards from equipment could include * Untidiness e.g. toys, equipment left in corridors on stairs or blocking fire exits. * Poor maintenance, e.g. frayed wiring or broken equipment * Unsafe practice, e.g. overload sockets or trailing flexes * Lack of awareness of hazards, e.g. hot surfaces or moving parts All equipment must work and function correctly; it must be full maintained at all times. This could include fire fighting equipment, hoists and medical diagnostic equipment such as ECG or x-ray machines, it is very important that these are checked on a regular basis for any faults because the individual could be wrongly diagnosed. Computers and laptops now play as an important role in the care industry as they do in any other aspect of work. If they are positioned in an awkward place the individual can suffer from strain injuries, they can strain their vision if they have too much exposure to the screen, and incorrect sitting can lead to neck strain and back pains. Anything they need should be in reach or this can cau se them to overstretch and this could cause a fall. Infections You should always follow policies and procedures that are put in place; they are they to keep you and others around you safe. If you do not follow them you could cause unnecessary harm to you, your colleagues or individuals in your work place. Babies and older people are at a much greater risk of complications if they catch food borne infections, the incidence of MRSA in hospitals has highlighted the potentially devastating outcomes and effects of poor personal hygiene practices and over-prescription of antibiotics. On the national statistics website it shows that the number of deaths linked to MRSA in the UK from 1993 to 2006 rose to 1,625. But on the death certificates that mentioned it declined, and then in 2008 there was a fall of 23%. If the bacteria are on the skin then they can spread by touch, if it is in the nose or lungs then it can be passed on by droplet spread, by breathing or coughing over someone. But if the person is healthy then when they leave hospital it can just d isappear, this applies for people living with them; if they are healthy special precautions don’t need to be out in place. If it gets into the bloodstream through a wound then it can cause serious illness such as 1. Bone marrow infection 2. Blood poisoning 3. Septic shock 4. Septic arthritis 5. Meningitis 6. Abscesses anywhere within the body 7. Infection of the heart lining 8. Pneumonia Substances The hazardous waste does not stop after disposing of it as if his disposal of hazardous waste is not correct it could damage the health of all in the environment if not disposed of at all it can lead to infection and a spread of infection also. So when dealing with waste especially hazardous you has to make sure you depose of it correctly. Type of waste | Risk| How to dispose of the waste | Sharps (needles or syringes) | Risk of getting an infection off a dirty needle | All dirty needles must be out in a yellow box it can be small or large, it must be shut once it’s at its limit and it will not open once it has been closed. | Clinical dressings | Infection can occur | Must be placed in a yellow box which must be sealed with arrangements of the collection.| Body fluid (blood, urine, faeces, vomit. | A risk of infection | When cleaning up any of the waste you have to ensure gloves are worn it must be flushed down the toilet and then the toilet must be disinfected and if it was on the floor, disinfect where the waste was.| Soiled linen| Another risk of infection | They must be out in the special laundry bags which disintegrate when being washed.| There are a number of substances used in health and social care settings that are hazardous if misused. Cleaning fluids, medications and x-rays are all examples of substances found in health and social care settings. Chemicals can cause burns to the throat and oesophagus if swallowed by accident. Care should be taken at all times when administrating medication as it could be given to the wrong person which could lead to them suffering, or something as simple as the wrong dose. This type of mistake can have a devastating result for example in 2005 2 nurses miscalculated the dose of a drug needed to slow down a baby boys heart rate. He was given 10x the dose and he died. Hazardous working conditions Working conditions are aspects of your job, the hours that you work, the staffing levels and the staff relations. Even though we have tried to improve in the quality of health and social care as a result of regular inspections there are still with staff turnover and staff shortages this can lead to the staff rushing what they are doing with results in them ignoring the policies and procedures, this can lead to a risk of injury or accidents. Pay rates are low for early years workers and health and social care assistants, they are often only paid the minimum wage this can make people feel undervalued and make them less likely to follow policies and procedures. When there are staff shortages it can cause staff to be expected to do overtime, being a care worker or being in care work is physically and mentally demanding and too much of it is likely to cause staff to not perform to the best of their abilities, the more tired the staff are the more likely they are to make mistakes like miscalculating medication does, they will be less alert which could lead to them missing a sign that someone is ill. Stress is another reason of staff shortages, stress can be shown in many different ways people suffer from anxiety, sleep problems, digestive disorders, high blood pressure, and mood swings. None of these are good for a member of staff to be suffering with, it can lead to all sorts of problems in the health and social care setting. The vacancy rates for health and social care are higher than any other employment sectors in England, many care homes cannot recruit sufficient staff, and the shortages of staff have an impact of the quality of care given to those in the environment. Hazardous working practices The jobs you do when caring for people are called working practices. They include: 1. Moving and handling 2. Preparing food 3. Changing nappies 4. Giving injections/supervising 5. Giving injections 6. Supervising individuals with challenging behaviour You should always follow the procedures correctly because if you do not you can out yourself and others at harm. Care workers still suffer injuries related to moving people they care for even despite the manual handling regulations 1992. It was reported in 2003 that 80,000 nurses sustain back injuries at work each year, one third of all reported accidents involve moving and handling. The main hazards with moving and handling are that the handler may slip or trip over, stand in an awkward position, twist and overstretch, this can cause the handler to have neck or back pain, it can cause strain, and sprain or they could fracture a bone this could happen to either the handler or individual. They could end up with a permanent disability. Hazardous security systems Security systems are to keep staff and individuals safe from intruders, security systems are fitted in most health and social care settings. Residential homes normally keep the main door locked and only the people there have special keys and there family, or you have to buzz to get in. although this is a good thing, it could also be a bad thing as in fires it could waste time that could possibly save lives. All confidential information about the residents is withheld on the computer system and should be password protected all the filing cabinets should also be kept locked at all times. Section 2. Residential care There are different types of residential care homes, those for the older generation, people with disabilities and children who are looked after. In each of these settings health and safety has to taken extremely seriously, the carers have to make sure that the residents can escape in a fire, they have to make sure they are not putting one another in danger and that infections do not spread. It is important that the residents are informed about keeping themselves and others safe. In some of the residential homes the residents can come and go as they please but in a place where there may be little children or people that are confused that would not be allowed. They could put themselves in danger of getting ran over or hurt themselves. In winter time or in the colder weather, if they cannot find their way back or they don’t want to go back they could develop hypothermia. Child minder Settings where there are children should be very safe. Little children are curious and want to see and touch everything, they put things into their mouths lie toys or objects, this can cause them to choke or if they swallow a liquid such as a cleaning detergent they could be poisoned. They could open a gate and go wandering, cupboards, drawers could be opened which have poisonous substances in them, and they could climb and get stuck or distressed. When working in a preschool setting you have to be constantly vigilant and always alert and on the lookout for anything dangerous. Staffs is responsible for all activities the children take part in and therefore have to ensure that they are safe and not hazardous. Public environment Most parks are away from busy roads but there are a few which aren’t, in his case there is a danger of the child opening the gate and running out into the road, you have to watch your child at all times to ensure the safety of him/her. You also have to be vigilant of those in the park also, as there could be bigger children which could run into the child. Also if there is a skate park where the older children and teenagers chill you have to be careful for any empty glass bottles, also if older people are unsteady on their feet this can create a hazard for them. Sometimes people like to vandalize the park equipment and leave it in a dangerous state if you are looking after a child you should always check the park equipment before allowing your child on, this can easily stop an accident which may have happened. You may also have to asses if the child is age appropriate, if not you shouldn’t let the child on it in case of an injury, parks do have an impact absorbing floor normally which cushions the child’s fall, but accidents can still happen and you should always keep a close eye on your child. Some parks are frequente d by drug abusers; they may leave needles on the ground which would be extremely harmful to young children, so it would be a good idea to scan the ground. Dog owners tend to walk their dogs in the parks, dog faeces is a threat to children. There is such thing as toxicara which is a roundworm that can be present in dog faeces; this can potentially result in total blindness in one or both eyes. Parks are an idea place to take children to allow them to get some exercise and socialise with other children. Section 3 * Those receiving care, link to an older person and a young child: Young children are unable to recognize hazards themselves, their coordination is still developing. If substances are left lying around the child could get hold of them, this could lead to devastating consequences or even fatal, the child could be poisoned. You should always put locks on drawers and cupboards to ensure the children cannot get hold of hazardous substances. If things are left lying around such as toys a child could get hold of it and put it into their mouths if it too small or a toy is broken the child could choke. An older person could walk into things if they have limited vision or the lights are not bright enough. You should always make sure that the care setting is suitable and fits the residents needs. The main doors should always be locked in case there are residents who are confused, they may try to leave. An older person can be harmed if they need to be lifted into a bath or onto a bed, care should be taken when handling individuals and procedures should always be followed correctly. Workers in a setting: Workers sometimes come across Violent service users, this can put them at harm and they can be hurt. They could potentially fracture a bone. There may be faulty equipment which could be hazardous to the service provider as if they are lifting a service user and the equipment is broken the whole weight could be out on them and themselves and the individual could hurt themselves. If there is a shortage of staff and it is very busy the workers could feel stressed, stress can cause them to have anxiety and lack of sleep. If a member staff has had lack of sleep this will cause them to feel tired and they may not be als alert as they should be which can cause harm to themselves and the individual. If there are staff shortages tsome members of staff will be asked to work overtime, this can cause them to feel tired which again means that are not as vigilant as they would be. Support staff (eg caterers, cleaners, administrative), Cleaners are at a risk of being harmed by hazardous waste, if someone has soiled there bed sheets the cleaners have to take the sheets off the bed and put it into the wash, they come into contact with it which means germs can be passed. They also have to clean after someone has been sick again they can catch a bug or become unwell. Cleaners have to dispose of used dressing and needles they could catch an infection if they come into with them. * Visitors (eg relatives, friends, volunteers) Visitors need to be signed in and out in case of fires, if there was a fire and they are not signed in no one would know that they are there and they could at risk of being trapped in the building. Visitors are also at risk of catching infections or any bugs that are going around within the care setting. They should be informed of any infections before they visit. *

Philosophy of Education Essay -- Philosophy of Teaching Statement

Philosophy of Education One of the most privileged professions in the world today is teaching. Teachers can influence the youth of a culture in a way no one else can. Teachers have the honorable responsibility of education. Students develop mentally, socially, and ethically within the realm of academic education. While in this critical stage of development, students are given the laboratory of the classroom to test themselves in ways that are more risky after graduation. Teachers play a crucial role in this laboratory. I believe that the most important way I can serve my students while fulfilling this role is to have positive expectations, to continually reflect on my teaching habits and performance, and to use literature as a way to empower my students to be successful personally and professionally. I believe each student should be treated as an individual, and positive expectations should guide my interaction with each individual. Students have the potential and capability to achieve the highest success, and I will treat each of them with this in mind. Students should always believe this about themselves, and they are not going to unless others believe it with them. The development of a student’s self worth is very important during the middle and high school years. I believe many students fail academically because they don’t believe they are able to succeed, or they don’t value their success academically. These students need positive reinforcement and high expectations. Some students are set up to fail before they even enter the school building; a poor home environment can have negative effects on a student’s self worth and ability to study. These students need understanding, accommodations, and positive encourage... ...o help them make their own responsible decisions. After all, in a few years, they will be completely independent and should have practiced making their own decisions. I want to encourage my students to form their opinions about the choices they want to make through sound experiences and information before they get in the specific situations, thus making more informed and thoughtful decisions "in the moment." While entertaining the issues of culture itself, I would like to equip my students with the tools needed to read, write, comprehend, and verbally articulate their well-formulated ideas. By embedding the grammar, writing, reading, and critical thinking skills within the teaching of a a relative text, I hope to stretch the minds of my students more than just academically, but even in their development as a person. Literature can reach students in ways that I cannot.
