Chapter 14 – Biology Homework DiscussionMechanized agriculture has negative impacts on the environment such as soil loss, effects of fertilizer on aquatic ecosystems and bioaccumulation of pesticides. The vast tracts of bare land contribute to an increase in soil erosion by wind and water, and this has the consequence of soil loss in the region being transferred to another location. Lack of crop rotation leads to the depletion of nutrients in the soil, and this is only replaced through the application of fertilizers to reinforce the nutrients. Due to this, the use of fertilizers is increased and the soil become reach in inorganic chemicals and metals. In the event of rain, the nutrients leach through the soil finding their way to the water sources poisoning the aquatic life such as fish leading to their death. The increased use of pesticides on plants accumulates in the storage regions of the crops to which are consumed by humans, and this leads to the production of crops that are full of pesticides. Fossil fuel increases the rate of carbon emission, and this has the main effect of increasing greenhouse gases that lead to global warming. In a field where genetically identical seeds are planted, genetic diversity is lost, and plants of one kind can be found in the fields.

According to the cause of the problems, soil loss can be prevented through ensuring that there is enough vegetation cover such as grass to prevent soil erosion by wind and water. Sparingly use of fertilizers, and the replacement of fertilizers with organic fertilizers reduce the effect of fertilizers on the aquatic life and thus save the marine ecosystem. To prevent bioaccumulation of pesticides in the plants, more genetic differentiation is needed as well as the use of predators to prey on some pests. Fossil energy increases carbon emission into the atmosphere and thus need to be replaced with other energy sources such as electricity and the use of human resource to work on the fields to reduce carbon emission.

Multiple Regression

From the multiple regressions, this is the model

Y = 0.85 + 0.18×1 – 1.13×2 -0.20×3 +1.84×4 + 0.33×5 +0.23×6 – 12.89×7 + 5.39×8 -4.60×9 -20.37×10 -0.26×11 – 0.1×12 + 0.35×13

Note: Total Operating Expenses_05 is y Staffed beds_05 is x1 Medicare Days_05 is x2 Medicaid Days are x3 Total Surgeries_05 is x4 RN FTE_05 is x5 Occupancy is x6 Ownership is x7 System Membership is x8 Rural/Urban is x9 Teaching Affiliation is x10 Age 65 Plus 2005 is x11 Crime rate/100,000 population is x12 Uninsured 2005 is x13

Note: The regression coefficients have been reduced by scaling the data. Using the data, the way they are, one gets ridiculous coefficients. The total expenses_05 have been reduced by 1000000, Age 65 Plus, Uninsured 2005, Crime Rate, Total Surgeries, Medicaid day_05, Medicare days_05, and Occupancy has been reduced by 1000.

From the data a unit (1000) increase in staffed bed would result in a 170,000 increase in total operating expense. This variable has p value of 0.26, which is greater than 0.05 showing that this variable is not significant. A unit (1000) increase in Medicare days would result in a 1131 decrease in total operating expenses. Medicare days has a p value of 0.004 which is less than 0.05 showing that this variable is significant. A unit (1000) increase in Medicaid days would lead to 201 decreases in total operating expenses. Medicaid days is an insignificant variable because it has a p value greater than 0.05. A unit (1000) increase in total surgeries would result in a 1836 increase in the total operating expenses. Total surgeries is an insignificant variable because its p value is greater than 0.05. A unit increase in RN FTE would lead to a 329112 increase in total operating expenses. RN FTE has less than the critical value; this shows that the variable is significant. A unit (1000) increase in occupancy would lead to a 239 increase in total operating expenses. Occupancy is insignificant because it has a p value greater than 0.05. A unit expense in Ownership results into a 12890000 decrease in total operating expense. The variable ownership is insignificant because it is greater than the critical value 0.05. A unit increase in System membership results into a 4600000 decrease in total operating expense. System membership has a p value of 0.4 which is greater than 0.05 which shows that the variable is insignificant. A unit increase in Teaching Affiliation would lead to a 20370000 decrease in total operating expense. The p value of teaching affiliation is greater than the significant value 0.05 showing that the variable is insignificant. A unit (1000) increase in Age above 65 would result in a 260000 decrease in total expenses. The variable age has a p value greater than 0.05 showing that the variable age is insignificant. A unit (1000) increase in Crime rate would lead to a 100000 increase in total operating expenses. Crime rate has a p value of 0.89 which is greater than the critical value, demonstrating that the variable is insignificant. Lastly a unit increase in uninsured would lead to a 350000 increase in total expenses. Uninsured has a p value greater than 0.05 showing that the variable is insignificant. According to Allen (1997), if p value is greater than the critical value reject the variable is not significant.

Hypothesis Testing

From the data the null hypothesis is H0 = β1= β2= β3……= β13 = 0 against the alternative hypothesis H1 = β1= β2= β3……= β13≠0. From the anova table the calculated Fstatistics is 167.55 with 13 an 67 degrees of freedom. The tabulated Fstatistics is 1.797 which is below the Fcalculated. This means that we reject the null hypothesis and accept the alternative hypothesis. According to Cohen & Cohen (1983), if the f calculated is greater than the tabulated f value reject the null hypothesis.

R Square and Adjusted R Square

From the data, the adjusted R Square is 0.96 showing that the model explains 96% of the variation. This is a good fit. It is better to report adjusted R Square because it changes slightly if the variable is not significant. The value of R Square is 0.98 showing that the model is a good fit. This value is not commonly used because it fluctuates greatly, even if the variable is not significant (Hearley, 2010).

Interpretation

From the data, the Medicaid days_05, RN FTE_05, and Staffed beds_05 are the most significant variables in the model. This means to professionals that increasing the number of staffed beds in hospitals will increase the number of patients increasing the total operating expenses. Increasing the number of medicare days will decrease the total operating expenses in hosptials.

Murder, scandals, and the frightening world of surveillance all intertwine to form Francis Ford Coppola’s thriller, The Conversation. The viewer, engulfed in a restricted narration, explores the mystery Harry Caul, the protagonist, has caught himself in. A narration that begins objective with spurts of subjectivity is enhanced by the peculiar character traits of Harry. A plot that slowly unravels with surprising turns and leaves the viewer dangling at the end explores the dangers and horrors of surveillance.

Exploring the complex character of Harry Caul is key to understanding the movie. At the beginning we hear him say he doesn’t care about what the subjects he’s surveying are saying, just as long as he gets a fat recording. Arriving home from the job we find his door loaded with locks and upon entering an alarm goes off. On the floor is a birthday gift. Harry then calls the manager of the apartments and wants to know how the manager entered his home. Instantly in the first ten minutes of the film we are shown how secretive Mr. Caul is. He even is surprised that someone knows it’s his birthday. A birthday is something that almost every normal person wants shared and know. This fact emphasizes how he is a loner even more. His secrecy is even greater emphasized when he travels to see his girlfriend, Eve.

When he arrives Harry mentions it’s his birthday and she didn’t even know. This fact triggers Eve’s curiosity even more and she tries to find out more about him. Harry won’t tell her where he works or where he even lives. He becomes upset with these questions and tells her to stop. Someone becoming nervous about these simplest of questions shows incredible insecurity, and paranoia. This side of him is strange as it completely contrasts and is hypocritical with his treatment of other people.

Harry dives into other peoples’ lives, it’s his instinct to survey. Upon entering Eve’s apartment he stops at the top of the stairwell and listens. She then tells him that how he slowly and quietly puts the key into the door, then opens it quickly it seems as if he’s trying to catch her doing something. Eve even tells Harry she feels like he listens to her phone conversations, which he becomes instantly defensive over. This gives the viewer the thought that he might even of have tapped her line. Besides his dealings with Eve, Harry acts the same at his job.

In fact Harry is a leading surveillance expert. When listing notables to a surveillance convention his name is the top of the list. Everyone at the convention even knows his name and wants Harry to give the approval on their product. It seems that Harry is scared of being out done and having his life surveyed. This fear keeps him on top of the surveillance world.

As we follow the plot line and try to learn more about why the conversation is important we also are on the search to understand Harry Caul. This is a sub meaning that runs right along with the movie. This blankness and secrecy of Harry continue the mysteriousness of the plot.

The last yet most important trait is Harry’s conscience. At the beginning of the movie Harry tells his co-worker he doesn’t care what the subjects are talking about, just as long as he gets a fat recording. This impersonal attitude proves to be false. The fact that he does have a conscience creates conflict of the movie and leads into the cause and effect aspect.

The narration being restrictive we see all that Harry sees. When listening to the conversation Harry recorded the viewers are keyed onto certain passages. One is when the two subjects are talking about the bum. The woman says how sorry she feels for the bum and the man replies, “He isn’t hurting anyone.” To which she responds “neither are we.” Here we are given the notion that these two are lovers.

When Harry tries to turn his tapes into the director the assistant director attempts to take them. At this moment Harry begins to wonder what they are use for. He takes his tapes and leaves. But leaving the building Harry sees the two subjects he recorded. Here is where Harry’s conscience and the fact that the narration is restrictive plays a large part. Harry returns to his workshop and clarifies one point of the conversation that was hidden. Here the man subject says “He would kill us if he got the chance.” This is the important part of the movie. Harry’s conscience kicks in and we learn that he had once done some work where his tapes had some people killed. The fact that the two subjects seem to be innocent lovers nags at Harry. His line where said he didn’t care what was said on the tapes becomes null.

The simple cause is Harry made the recording. Interestingly enough the effect is that people might die, and another part of the effect is that Harry’s conscience kicks and he wants to stop what he started. This is a very interesting idea and shows the complexity of Harry’s character and how it ties into causality. He tries to trick himself into being impersonal, but his character won’t let him.

Another important piece of the meaning is how the story and plot interact. The plot draws you along throughout the movie giving you bits and pieces of what the story is. Up through the murder scene and briefly after the viewers are to believe that the director’s wife was cheating on him. That was the reason why the recordings were made. The viewer believes this to be the story, yet after the murder Harry tries to see the director but he isn’t admitted. On the way out of the building Harry sees the girl however. At this moment a whole different chunk of the story is shown. This new chunk is that of a conspiracy.

The plot and narration does an excellent job of tricking the viewer. Through its restrictive view and a few objective scenes where Harry feels upset and you see the two subjects of the recording the viewer is almost positive it is a simple affair ending in murder. The temporal order of all the flashbacks had an important role in tricking the viewer. Through constant repetition of the flashbacks the viewer is keyed into their conversation, which makes them seem compassionate, innocent. The compassion they show the bum is implanted in your thoughts. This set the viewer up for even a greater surprise.

Now the story is expanded. It now includes how the assistant director and the wife used Harry to further their scheme. The ending comes abruptly after this leaving the viewer hanging. The story isn’t resolved. The plot only showed you the middle chunk of the story. By leaving this line open it furthers the mystery. Adding to this mystery is the fact that Harry, the great bugger, is now under surveillance. Incredibly he can’t even figure out how. Showing once again his incredible fear of being watched and listened to he rips his whole apartment apart in vein. Here another question is left. What is going to happen to Harry? Is he going to be able to out smart the assistant director? Will they kill him like the director? These questions add to the mysteriousness of the movie.

From the beginning with sounds that the viewer wonders what they are and could consider them non-diegetic, then realizes it is the recording of voice, to the end where the story is left in question the viewer never once has a complete understanding. The character of Harry Caul is a mystery in itself. Thoughout the movie his strange traits are revealed. Then through a restrictive narration you embark on this mystery man’s journey, which is also strange and deceiving. The flashbacks you can’t understand. And when you realize that there was a huge conspiracy, you still don’t receive a complete conclusion. Though these forms of narrative the director and writers formed a mysterious and sinister vision of surveillance. A disturbing vision that the viewer is left to think and worry about.

Multiple Sclerosis (MS)

Pathophysiological Phenomenon

Multiple sclerosis common abbreviated as MS is an autoimmune disorder that affects the Central Nervous System (CNS). MS results when the immune cells start invading the brain as well as the spinal cord resulting in its inflammation, tissue damage as well as neurodegeneration of white matter which is myelin (Norris, 2018). Researchers have tried to identify various causes of MS but currently there is no solid cause of this autoimmune disorder. Pathologically multiple sclerosis is defined as the presence of scars as a result of inflammation. The immune system erodes away the protective layer of the nerves referred to as the myelin, this affects the communication between the brain and other body organs.

There are four main forms of MS that have been recognized: relapsing-remitting MS, primary progressive MS, secondary progressive MS and progressive relapsing MS (Faissner, 2019). According to a studies all these forms of MS have different neuropathologists a clear indication that multiple sclerosis comes from a variety of a group of related heterogeneous diseases. Most common form of MS that tend to occur is the relapsing-remitting MS. Course of MS tends to vary between patients and is usually not predictable. Although the cause is unknown it involves a combination of genetic susceptibility in combination with non-genetic triggers including certain non-genetic triggers including environmental factors, certain viruses and also metabolism: A combination of these factors have been believed to result in an autoimmune disorder that attacks the Central Nervous System.

Incidence of Phenomenon and Impact

According to the National Institute of Health, it is estimated that MS affects roughly 400,000 people in the United States, this is double the number from when the first national research occurred in the year 1975 (Norris, 2016). Globally, National MS Society approximates more than 2.3 million people globally are living with multiple sclerosis. From the MS Discovery Forum, approximately there are 200 new cases reported every week in the United States. According to statistics, Americans living further from the equator, that is southern U.S. States have higher rates of MS as compared to those living in the northern states (Dilokthornsaku, 2016). Incidences of MS are also quite higher in people living in Norther Europe which experience cold climatic conditions. Lowest risk seems to occur among Asians, Africans and the Native Americans as well. In children, prevalence is not as high, according to a research by Nashi M. et al (2017), children make up only 4% of all MS cases. The highest number of individuals with MS are aged between 45 and 49 years an indication that age is a factor when it comes to MS.

There are various risk factors that can increase the development of MS; such as age, race, sex, family history, climate, season of birth and vitamin D. In this regard women are twice more likely to be affected in comparison to their male counterparts. The onset of the disease is often between 20 and 30 years although it can occur at any given age (Norris, 2018). Family history is also a risk factor; if one of your immediate family members has MS then it’s highly likely that one can develop the disease because of the genetic disposition associated with Multiple Sclerosis. Low exposure to sunlight leads to a deficiency in Vitamin D, which correlates with a higher risk of MS which may explain why cold areas have higher cases of MS as compared to areas with warm or cool climatic conditions. Viruses such as Epstein Bar have also been linked with MS. Patients born with MS are more frequent in winter and spring in comparison to autumn where it’s less frequent. It is argued that this could be as a result of lower vitamin D during the pregnancy period.

MS has an impact on the society both physically, financially and economically. The firs impact that can be felt especially because it is a disorder that leads to loss of mobility functions. MS can affect an individual’s way of life, this is due to high medical cost and emotional toil an affected person. MS has resulted in intangible costs, direct costs and indirect costs. Various cost estimates per person battling MS have been published indicating how high the course of treatment is. MS does not adversely affect individuals and families only but also the society at large. It is quite challenging given the amount of research and funding people invest in battling MS. The economic impact of MS on a particular country can be arrived at by identifying the number of MS patients in a country. In regards to intangible cost people with MS are dependent on care givers, since they need help in performing daily tasks. MS patients cannot carry out mundane tasks on their own due to physical and cognitive impairments. However, the data collected showcases that majority of care givers are informal, they are not certified care givers and lack proper training (Santos, 2019). A majority of the care givers are spouses or immediate family members. The time spent by informal care givers taking care of their loved ones may led up to psychological stress and anxiety. This is because they not only have to sacrifice their time; they also incur treatment cost and physical burden thus it can be deterrent to their physical health as well (Santos, 2019).

According to a research by Raggi A. et al (2016) people with MS most likely end up losing or quitting their jobs, work loss can also be cited as one of the indirect costs of MS. MS patient are easily fatigued, have difficulty in speech delivery, cognitive impairment and also experience difficulty in mobility. These symptoms are hindrance at any place of work especially one that are physically challenging. These significantly affects the labor force, whereby MS patients have to search for less tasking jobs one that require minimum physicality and low stress, however in most instances this means they have to work low paying wages. These can also affect the informal caregivers who have to forfeit their jobs and sacrifice their time to care for the patient. Studies indicate that informal caregivers experience works strain having to balance between their job and care giving.

Early mortality as a result of MS can also be identified as an indirect cost. Economic strain due to the underlying economic gain that could have been made. People who die due to MS would have contributed to the working force of the nation thus helping build on the nation’s economy (Ponzio, 2015). One of the direct costs is the medical and non-medical costs. Medical costs include a variety of things such as: inpatient and outpatient care, rehabilitation, drug prescription, physician services and other medical supplies. Direct cost of the medical cost can be estimated to range from 10,000 euros per person. Direct non-medical cost includes the modifications needed to make mobility and the stay of MS patient quite wholesome. Modifications such as mobility whereby wheelchairs will be needed and varying form of transportations, which require funds. To most families getting enough funds to ensure their loved one is completely taken care off and his needs are met may be MS not only affects an individual’s health it encompasses a far wider scope such as family and friends as well as the society.

Pathophysiology and Recent Findings

Multiple Sclerosis is among the most common forms of neurological disorders. As stated earlier, there is little knowledge as to the causes of this autoimmune disorder but with age, there has been so many research by the scientist to try and explain the results of this disease. Recent findings argue that MS may not be just a single disease but rather it is a wider spectrum involving both non-genetic trigger as well as genetic susceptibility of a person. In regards to MS pathology illustrates the conditions that correlate with the lesions. Physiology on the other hand illustrates the different actions that resulted to the development of lesions. Lesions are visible through magnetic resonance; they vary in sizes some are quite small while other are the size of a golf ball. Pathologically MS can be defined as the existence of sclerosis in the central nervous system, distributed in space. Simon Faissner explains how Physiologically MS destroys axons that are in the CNS that are shielded by the myelin (Faissner, 2019). The MS also attacks the nerve cell close to the brains gray matter. This leads to the damaging of axons in the spinal cord, optic nerve and brain. This hinders the transmission of visual information from the eye to the brain (Zephir,2018). The progression of MS in the brain results in the shrinkage of the cerebral cortex. In the case that the MS exacerbates the inflammation damages the myelin and the axons within that space. The signs and symptoms of MS also vary depending on the location of the lesion and the extent of the inflammation.

The cause of MS varies for each individual; the time span and onset of each symptom vary with the specific type. According to Faissner et al (2019)there are 4 types of MS, they derive their names from the progression of the symptoms. First is the Relapsing-remitting MS, the symptoms come in forms of attacks; this is referred to as a relapse. People can recover or return to their disabled form in between attacks. A remission is the period when the disease is inactive. A relapse may occur in a year, month or even week. A majority of the people are initially diagnosed with this form. The second form of MS is the secondary-progressive MS; this are individuals who have past experiences with relapses. However gradually symptoms begin to appear which lead to deterioration in health. Relapsing-remitting MS if left untreated can result in Secondary – progressive MS. The third form of MS is the primary-progressive MS it is associated with continuous worsening of the symptoms without any relapses. It’s also characterized with minor reliefs and it’s less common. The last form of MS and the rarest is the progressive-relapsing MS; it’s marked with steady deterioration of the symptoms and acute relapses. Some of the early of MS include: loose urine bladder, blurry and double vision, constant dizziness, muscle spasms, weakness and stiffness, numbness in the leg and face, and difficulty in balance (Dobson, 2019). In later stages of the MS various symptoms may arise such as, fatigue, cognitive dysfunction and depression. Stiffens and muscle spasms can affect the balance which hinders standing and walking. In more severe cases it may lead to paralysis. Research has found that when people with MS experience worse fatigue when they have a high fever or when they are exposed to heat (Dobson, 2019). Pain is not considered one of the first sign of MS. Pain shooting down the leg and limb spasm can be considered as symptoms of MS. Relapses in the MS can be indications of further damages in the brain. Relapses can either be mild or severe and also its duration varies.

The National Institute of Neurological Disorders and Strokes is spearheading the funding of research on the brain and nervous system. Although no definitive cause of MS has been established major strides have been made in the research of MS. In regards to treatment strides have been made to curb exacerbation of MS. New developments such as the biomarkers that have been developed to help monitor and diagnose MS. Biomarkers help in monitoring the progression of the disease. NINDS is currently monitoring various programs such as the Central Vein Sign in MS; it’s a study researching if scientist can be able to distinguish the central veins passing through brain plaques, in an attempt to distinguish MS from other neurological disorder (Absinta, 2019). Achieving this will ensure great growth and milestone in this field. Genetic research is also exploring the role genes have to play and whether it’s a potential increased risk for MS.

Medical Differential Diagnosis

There has been a misconception that attack on the CNS causing demyelination is an indication that an individual may be suffering from acute multiple sclerosis. There are various diseases that can mimic MS, this include Lyme disease, migraine, radiological isolated syndrome, spondyplopathies, neuropathy, lupus, stroke and vasculitis. These diseases have the ability to mimic MS and many a times misdiagnosis are made due to the similarity in symptoms (Thompson, 2018). Differential diagnosis entails narrowing down to the specific diagnosis. There are several differential diagnoses that are applied to the MS in order for physicians to really establish that a person is suffering from MS. The first is the spinal cord neoplasm where metastatic as well as spinal cold neoplasm including ependymomas and astrocytomas are considered. When imaging is conducted, and there is the presence of cysts as well as hemorrhage then the diagnosis of neoplasm is supported. ADEM is another differential diagnosis. ADEM is a post infectious autoimmune attack on either the brain or the spinal cord. It is characterized by onset of motor and sensory nerve dysfunction with encephalopathy which later proceeds to coma eventually resulting in death. MRI is useful in pointing out occurrence of lesions in cases of ADEM or MS. The condition can be treated with the use of steroids before biopsy is considered. Another differential diagnosis is Baló concentric sclerosis but is associated with inflammation of cerebrospinal fluid, however, it has fulminant progression when compared to multiple sclerosis (Sand, 2015).

Sarcoidosis is another differential diagnosis characterized with enhancement of white and pia matter lesions when imaging is done. Radiation myelitis which is also characterized with demyelination as well as presence of the spinal cord lesion may lead to its diagnosis as MS. Finally, another differential diagnoses are the vasculitis processes including lupus erythematosus leading to spinal lesions that may be seen as mimicking MS as there are multiple lesions that are present. Clinical history is important in helping one establish the right diagnosis. Doctors adapt various methods, to either rule out or confirm a diagnosis. This includes physical examination, medical history and neurological exam. However, the physician can suggest MRI scans and lumbar puncture. MRI which can be used adjunct to clinical diagnosis in looking at presence of lesions even when at times the scan appears normal (Norris, 2018).

Collaborative treatment options

MS has no cures however there are treatments that have been adopted that can derail the progression of the disease. Plasma exchange effective in treating flare ups, in individuals with exacerbating forms of MS. Can be used as substitute of methylprednisolone. Plasma exchange entails replace harmful Plasma from an individual’s blood with replacement Plasma, then transfusion it back (Moser, 2019). It’s important to note that this treatment has not been proven to be effective for both secondary and chronic progressive MS.

Corictosteroids methylprednisolone is injected into the vein; it is prescribed for 3-5 days. The steroids aid in suppressing the inflammation of the immune system, this ensures quick recovery from attacks. The drug does not have any long term effect on the progression of the disease. Disease – altering system vary from injected, infusion and oral treatment. Injected treatment uses Beta interferon drug which helps to regulate immune cells. This drug however has certain side effects including depression and flu-like symptoms (Auricchio, 2017). Another injection is use of Glatiramare acetate that is effective as it aids in balancing the immune cells. Its side effects are quite mild, mainly swelling in the injected area. Infusion treatment is another option whereby Natalizumab is administered once in a month and its main purpose is to prevent the immune system cells from damaging the brain and spinal cord. Although it has been deemed effective it poses serious risk for viral infection of the brain. Alemtuzumabb is also used it mainly targets to destroy the protein on the top of immune cells. It’s administered for five consecutive days and then a follow up a year later for 3 days’ infusion. These drugs may increase the autoimmune disorder therefore it’s recommended for people who have two or more inadequate MS therapies. Finally, for the oral treatment, there are various drugs that are used including Teriflunomide that reduces the swelling of activated immune cells. It is a once daily form of medication. Its side effect is nausea, hair loss and liver damage. Dirixomel fumarate is also used and it is administered twice daily (Auricchio, 2017). This drug makes the immune system less inflammatory, this helps manage the progress of the MS.

Tremors are also common in MS patients, whereby they experience uncontrollable shaking. Medication such as clonazepam can be helpful. Assistive devices, such as weight in spoons are quite helpful. Muscle spasm and weakness is also a common symptom. Mild muscle spasms are manageable through stretching and exercising it can be through yoga, water or physical therapy. It is recommended that people with MS stay physically active this reduces stiffness of the bones. Fatigue can be both cognitive and physical, however, it can be battled through engaging in daily physical activities that are mild or moderate (Feys, 2016). Also drugs such as modanfil help in battling fatigue. Occupational therapy aids people in walking while also managing your energy. Joining support groups helps in managing the stress. Support group provides an environment for one to talk with others on how they feel being a safe space. Although MS still has no cure, people are managing to live with MS through its management

Muscle Adaptations to Anaerobic Training

Anaerobic training has to do with high-intensity training methods whereby the source of energy does not rely upon the use of oxygen. The number of sports and the sprinting, high-intensity training relies on anaerobic training to attain top performance. The body goes through a series of adaptations that have consistent anaerobic training, with virtually every system in the body affected. From the endocrine system to the cardiovascular system anaerobic training gives adaptations that are beneficial for high performance and good health. Worth noting, anaerobic training mainly focuses on anaerobic energy systems such as alactacid and lactic acid and getting physiological adaptations that benefit these systems. This text highlights the muscle adaptations to anaerobic training.

Hypertrophy is one of the adaptations through which anaerobic training boosts the size of muscles. Hypertrophy is achieved by optimizing the levels of actin and myosin, which are the proteins that facilitate the movement of muscles on a microscopic level. Anaerobic training inhibits the degradation proves and boosts the production of such proteins. This causes increased myofibrils levels, which are an additional component of the muscle cell. However, whether anaerobic training causes hyperplasia is still unknown. Hyperplasia is the increase in the number of muscle fibers and not the size as it would be hard to count it. The magnitude of muscle growth and protein synthesis depends on the nutrition, hormone receptor response, hydration, and training program (Sözen, 2018). A strategy which incorporates a combination of metabolic and mechanical factors tend to optimize hypertrophy. Mechanical factors such as eccentric actions, heavy loads, and low-to-moderate volumes. Metabolic factors main focus is putting stress on the glycolytic energy system that is said to take effect after 43 seconds of high volume and high-intensity activity with short periods of rest.

Fiber-type transitions are another muscle adaptation to anaerobic training. Essentially, the proportion of fiber types that an individual has is relatively unchangeable and is determined by genetics (Vermeulen, Plancke, Boshuizen, de Bruijn, & Delesalle, 2017). However, hypertrophy makes Type-II fibers to change into Type-I fibers. Additionally, hypertrophy makes Type II-x fibers to change and behave more like Type II-a which is viewed as the capacity to respond to low stimulus levels.

Architectural and structural changes are also muscle adaptations that take place during anaerobic training. Structural changes boost expression of strength and muscle function. Anaerobic training leads to increased density of cytoplasm, myofibrils, and activity of Na-K ATPase. It also ignites an increase in t-tubule density and sarcoplasmic reticulum. Two architectural changes influence how force is transmitted to bones and tendons. There is boosted muscle fascicle length and also increased cross-sectional area in the muscle fiber causing resulting in boosted pennation angle.

Decreased capillary and mitochondrial density are also additional muscle adaptations to anaerobic training. The gross number of capillaries and mitochondria stays the same however the density reduces due to hypertrophy. This means that the number of capillaries and mitochondria per muscle is low, but the total number remains the same as before hypertrophy. However, this does not affect aerobic performance due to the improved efficiency of capillaries and mitochondria. Raising buffering capacity is efficient for acid-base balance. One can buffer out lactic acid more faster. It is a by-product of the metabolic processes which is heavily depended upon during anaerobic exercise. This leads to delayed fatigue during exercise hence leading to opportunities for more longer and productive training sessions. Additionally, the overall muscle efficiency improves due to increased storage of glycogen, ATP, and creatine phosphate. Additionally, the enzymes which function by using the substrates in the metabolic processes are active and more, by extension, more efficient.

Chapter 9 Reflection- Conflict Theory

Chapter 9 talks about conflict theory, a societal construction explaining the conflicts in society as caused by inequality and other social factors. There are many types of conflict theories, and they fall under different categories. For example, race-based conflict theory suggests that conflict in society is caused by the whites being privileged over people of color and other minority groups.

However, the issue of racism is not the only thing that determines conflict theory explanation as an economic power. Especially in a capitalistic nation like the United States, those who have money can be said to be untouchable. In contrast, those who are not financially stable are the ones who find themselves in crime most of the time. Therefore, conflict theory explains the societal conflicts that arise due to competition between those who have and those who do not have. It also discusses the impacts of the many different factors that come into play when discussing these factors.

Chapter 9

The Egyptians and the Mayans had some of the most elaborate rituals when it came to the burials of their kings. The Egyptians preserved their pharaohs in elaborate tombs enclosed in ornate tombs that still attract tourists to this day. The Mayans, though less detailed, still had some remarkable traditions surrounding the burial of their kings. The tow kingdoms existed at different periods and in different places, but there are several reasons why they share similarities in the burial rites. These include the high esteem with which they held their kings and rulers and a shared belief in life after death.

Kings and rulers were held in high esteem by the people over whom they ruled. The Egyptians believed that their Pharaohs were wise men close to the gods. The kings were therefore highly respected, and this is shown in their burial place and the rituals surrounding their death. Their coffins were made of wood and gold, to show that their kings were just as precious in life as in death. The Egyptians also took care to bury their kings to maintain a connection with the goods such as Ra, the god of the sun. The Mayans shared similar beliefs in the elaborate tombs built for their kings and the shrines on top of the pyramids. The kings would still hold a special place in their kingdom even after death.

The second reason why the Mayans and Egyptians had similar burial rituals is that they believed in life after death. Egyptian Pharaohs were mummified, which kept their bodies intact for many years. It was thought that the spirit lived on after death and needed to get back to the body for rest. The Mayans allowed their kings to decompose, but the bones were later sprinkled with mercury oxide. Such after death rituals show a belief in life after death. The pyramids of both Mayans and Egyptians contained everyday objects and paintings, an indication of the continuity of life after death.

Multiple Sclerosis disease

Multiple Sclerosis (MS) is a chronic, often disabling disease that randomly attacks the central nervous system (brain and spinal cord). The progress, severity and specific symptoms of the disease cannot be predicted; symptoms may range from tingling and numbness to paralysis and blindness. MS is a devastating disease because people live with its unpredictable physical and emotional effects for the rest of their lives. MS is a well-known disease, but poorly understood. In the United States there are approximately 200 new cases diagnosed each week; MS is a common disease and not always caused by genetics. Therefore, I feel we all need to have a better understanding of this disease that has no cure yet. I hope to make MS more understanding in my paper. In my paper I will explain what MS is, who gets MS, what MS has to do with the metabolism, some new techniques being used to pinpoint genetic factors, what some of the symptoms of MS are.

Multiple Sclerosis (MS) is a progressive disabling illness that affects nerve cells in the brain and spinal cord (Bernard). Under normal conditions an insulating sheath made of fatty myelin, which speeds the passage of nerve impulses, surrounds these nerve cells. In MS, this myelin sheath is inflamed or damaged, disrupting nerve impulses and leaving areas of scarring (sclerosis). The disruption of nerve signals within the brain and spinal cord causes a variety of symptoms that may affect vision, sensation, and body movements. These symptoms usually wax and wane through a series of relapses (episodes when symptoms suddenly get worse) alternating with remissions (periods of recovery, when symptoms improve). (Brunnscheiler) For many patients, a long history of MS attacks over several decades’ leads to slowly progressing disability, but for others the disability is more rapid and severe. MS is a life-long chronic disease diagnosed primarily in young adults who have a virtually normal life expectancy. Consequently, the economic, social, and medical costs associated with the disease are significant. Estimates place the annual costs of MS in the United States in excess of $2.5 billion. (Melvin) No one knows exactly how many people have MS. It is believed that, currently, there are approximately 250,000 to 350,000 people in the United States with MS diagnosed by a physician. (Boyden) This estimate suggests that approximately 200 new cases be diagnosed each week. Also, MS is the most common nerve disease to develop in young persons after birth, and it affects over 1 million young adults worldwide. Close relatives of a person with MS are 8 times more likely than average to develop the disease themselves, and children of a person with MS run 30 to 50 times the average risk. (Waxman) Most people experience their first symptoms of MS between the ages of 20 and 40, but a diagnosis is often delayed. This is due to both the transitory nature of the disease and the lack of a specific diagnostic test–specific symptoms and changes in the brain must develop before the diagnosis is confirmed. (Health Central) Although scientists have documented cases of MS in young children and elderly adults, symptoms rarely begin before age 15 or after age 60. Whites are more than twice as likely as other races to develop MS. In general, women are affected at almost twice the rate of men; however, among patients who develop the symptoms of MS at a later age, the gender ratio is more balanced. (Waxman) To understand what is happening when a person has MS, it is first necessary to know a little about how the healthy immune system works. The immune system — a complex network of specialized cells and organs — defends the body against attacks by “foreign” invaders such as bacteria, viruses, fungi, and parasites. It does this by seeking out and destroying the interlopers as they enter the body. Substances capable of triggering an immune response are called antigens. (Hofmann) The immune system displays both enormous diversity and extraordinary specificity. (Hofmann) It can recognize millions of distinctive foreign molecules and produce its own molecules and cells to match up with and counteract each of them. In order to have room for enough cells to match the millions of possible foreign invaders, the immune system stores just a few cells for each specific antigen. When an antigen appears, those few specifically matched cells are stimulated to multiply into a full-scale army. Later, to prevent this army from overextending, powerful mechanisms to suppress the immune response come into play. T-cells, so named because they are processed in the thymus, appear to play a particularly important role in MS. They travel widely and continuously throughout the body patrolling for foreign invaders. In order to recognize and respond to each specific antigen, each T cell’s surface carries special receptor molecules for particular antigens. T cells contribute to the body’s defenses in two major ways. Regulatory T cells help orchestrate the elaborate immune system. (Kaser) For instance, they assist other cells to make antibodies, proteins programmed to match one specific antigen much as a key matches a lock. Antibodies typically interact with circulating antigens, such as bacteria, but are unable to penetrate living cells. Chief among the regulatory T cells is those known as helper (or inducer) cells. Helper T cells are essential for activating the body’s defenses against foreign substances. (Kaser) Yet another subset of regulatory T cells acts to turn off, or suppress, various immune system cells when their job is done. Killer T cells, on the other hand, directly attack diseased or damaged body cells by binding to them and bombarding them with lethal chemicals called cytokines. ( Kaser) Since T cells can attack cells directly, they must be able to discriminate between “self” cells (those of the body) and “nonself” cells (foreign invaders). To enable the immune system to distinguish the self, each body cell carries identifying molecules on its surface. T cells likely to react against the self are usually eliminated before leaving the thymus; the remaining T cells recognize the molecular markers and coexist peaceably with body tissues in a state of self-tolerance. In autoimmune diseases such as MS, the detente between the immune system and the body is disrupted when the immune system seems to wrongly identify self as nonself and declares war on the part of the body (myelin) it no longer recognizes. (Hauser) Through intensive research efforts, scientists are unraveling the complex secrets of the malfunctioning immune system of patients with MS. Components of myelin such as myelin basic protein have been the focus of much research because, when injected into laboratory animals, they can precipitate experimental allergic encephalomyelitis (EAE), a chronic relapsing brain and spinal cord disease that resembles MS. The injected myelin probably stimulates the immune system to produce anti-myelin T cells that attack the animal’s own myelin. (Leuven) Investigators are also looking for abnormalities or malfunctions in the blood/brain barrier, a protective membrane that controls the passage of substances from the blood into the central nervous system. It is possible that, in MS, components of the immune system get through the barrier and cause nervous system damage. Scientists have studied a number of infectious agents (such as viruses) that have been suspected of causing MS, but have been unable to implicate any one particular agent. (Mayo Clinic) Viral infections are usually accompanied by inflammation and the production of gamma interferon, a naturally occurring body chemical that has been shown to worsen the clinical course of MS. It is possible that the immune response to viral infections may themselves precipitate an MS attack. The genes a person inherits may help determine whether that person is at increased risk for developing MS. ( Melvin) While there is evidence from studies that this genetic component exists, it appears to be only one factor among several. Most likely an individual s genetic blueprint ultimately determines if that individual will be susceptible to a triggering factor, which in turn initiates the autoimmune process that leads to the development of MS. In the past few years, scientists have developed a set of tools that gives them the ability to pinpoint the genetic factors that make a person susceptible to MS. These tools are the methods of molecular genetics techniques used to isolate and determine the chemical structure of genes. (Colin) In the 1980s, scientists began to apply the tools of molecular genetics to human diseases caused by defects in single genes. This work led to major advances in understanding diseases such as Duchenne muscular dystrophy and cystic fibrosis. The situation for diseases such as multiple sclerosis is more complicated. Scientists now believe that a person is susceptible to multiple sclerosis only if he or she inherits an unlucky combination of several genes. (Colin) Advances in molecular genetics and the identification of large families in which several members have MS “multiplex” MS families have made possible research to uncover MS susceptibility genes. Since 1991, the National MS Society has supported an international project searching for these genes. (National Multiple Sclerosis Society) However, even though genetic (inherited) factors seem to play a large role in the development of MS, no single MS gene has been identified so far. Instead, scientists suspect that MS develops because of the influence of several genes acting together. Many multiplex families from throughout the world have agreed to participate in these studies. The researchers are looking for patterns of genetic material that are consistently inherited by people with MS. These recognizable patterns are called “DNA markers.” (Melvin) When one of these markers is identified, scientists focus on that area, seeking additional markers closer to that gene. Eventually the location of that gene can be identified. This process of moving closer to the gene until it is identified has to be repeated for each of the marker regions from the multiplex families. (Melvin) By 1996, as many as 20 locations that may contain genes contributing to MS were identified, but no single gene was shown to have a major influence on susceptibility to MS. (Melvin) Research will likely find that other, as yet unidentified, genes contribute to MS. After the location of each susceptibility gene is identified, the role that the gene plays in the immune system and neuralgic aspects of people with MS will have to be determined. Because the immune system is so involved in MS, many scientists think at least some of the susceptibility genes are related to the immune system. Already there have been reports linking some immune system genes to MS. Further indications that more than one gene is involved in MS susceptibility comes from studies of families in which more than one member has MS. Several research teams found that people with MS inherit certain regions on individual genes more frequently than people without MS. Of particular interest is the human leukocyte antigen (HLA) or major histocompatibility complex region on chromosome 6. HLAs are genetically determined proteins that influence the immune system. ( Kaser) The HLA patterns of MS patients tend to be different from those of people without the disease. Investigations in northern Europe and America have detected three HLAs that are more prevalent in people with MS than in the general population. Studies of American MS patients have shown that people with MS also tend to exhibit these HLAs in combination–that is, they have more than one of the three HLAs–more frequently than the rest of the population. Furthermore, there is evidence that different combinations of the HLAs may correspond to variations in disease severity and progression. (Kaser) Studies of families with multiple cases of MS and research comparing genetic regions of humans to those of mice with EAE suggest that another area related to MS susceptibility may be located on chromosome 5. Other regions on chromosomes 2, 3, 7, 11, 17, 19, and X have also been identified as possibly containing genes involved in the development of MS. (Hauser) These studies strengthen the theory that MS is the result of a number of factors rather than a single gene or other agent. Development of MS is likely to be influenced by the interactions of a number of genes, each of which (individually) has only a modest effect. Additional studies are needed to specifically pinpoint which genes are involved, determine their function, and learn how each gene’s interactions with other genes and with the environment make an individual susceptible to MS. In addition to leading to better ways to diagnose MS, such studies should yield clues to the underlying causes of MS and, eventually, to better treatments or a way to prevent the disease. (Ronthal) Finding the genes responsible for susceptibility to MS may lead to the development of new and more effective ways to treat the disease. Such research could also uncover the basic cause of the disease and help predict the course of the disease in an individual. This would make it easier for physicians to tailor therapies and provide information to help people make life decisions. Another possible benefit may be the early diagnosis of people in families where one or more member already has MS. Many physicians believe that the earlier MS is diagnosed and treatment begun, the better the outcome will be. Symptoms of MS may be mild or severe, of long duration or short, and may appear in various combinations, depending on the area of the nervous system affected. Complete or partial remission of symptoms, especially in the early stages of the disease, occurs in approximately 70 percent of MS patients. The initial symptom of MS is often blurred or double vision, red-green color distortion, or even blindness in one eye. (Brunnscheiler) Inexplicably, visual problems tend to clear up in the later stages of MS. Inflammatory problems of the optic nerve may be diagnosed as retrobulbar or optic neuritis. Fifty-five percent of MS patients will have an attack of optic neuritis at some time or other and it will be the first symptom of MS in approximately 15 percent. This has led to general recognition of optic neuritis as an early sign of MS, especially if tests also reveal abnormalities in the patient’s spinal fluid. (National Multiple Sclerosis Society) Most MS patients experience muscle weakness in their extremities and difficulty with coordination and balance at some time during the course of the disease. These symptoms may be severe enough to impair walking or even standing. In the worst cases, MS can produce partial or complete paralysis. Spasticity, the involuntary increased tone of muscles leading to stiffness and spasms–is common, as is fatigue. (Brunnscheiler) Fatigue may be triggered by physical exertion and improve with rest, or it may take the form of a constant and persistent tiredness. Most people with MS also exhibit paresthesias, transitory abnormal sensory feelings such as numbness, prickling, or “pins and needles” sensations; uncommonly, some may also experience pain. Loss of sensation sometimes occurs. Speech impediments, tremors, and dizziness are other frequent complaints. Occasionally, people with MS have hearing loss. (Brunnscheiler; National Multiple Sclerosis Society) Approximately half of all people with MS experience cognitive impairments such as difficulties with concentration, attention, memory, and poor judgment, but such symptoms are usually mild and are frequently overlooked. In fact, they are often detectable only through comprehensive testing. Patients themselves may be unaware of their cognitive loss; it is often a family member or friend who first notices a deficit. Such impairments are usually mild, rarely disabling, and intellectual and language abilities are generally spared. (Brunnscheiler) Cognitive symptoms occur when lesions develop in brain areas responsible for information processing. (Brunnscheiler) These deficits tend to become more apparent as the information to be processed becomes more complex. Fatigue may also add to processing difficulties. Scientists do not yet know whether altered cognition in MS reflects problems with information acquisition, retrieval, or a combination of both. Types of memory problems may differ depending on the individual’s disease course (relapsing-remitting, primary-progressive, etc.), but there does not appear to be any direct correlation between duration of illness and severity of cognitive dysfunction. (National Multiple Sclerosis Society) Depression, which is unrelated to cognitive problems, is another common feature of MS. (Brunnscheiler) In addition, about 10 percent of patients suffer from more severe psychotic disorders such as manic-depression and paranoia. Five percent may experience episodes of inappropriate euphoria and despair–unrelated to the patient’s actual emotional state known as “laughing/weeping syndrome.” This syndrome is thought to be due to demyelination in the brainstem, the area of the brain that controls facial expression and emotions, and is usually seen only in severe cases. (National Multiple Sclerosis Society) As the disease progresses, sexual dysfunction may become a problem. Bowel and bladder control may also be lost. (Health Central) In about 60 percent of MS patients, heat, whether generated by temperatures outside the body or by exercise may cause temporary worsening of many MS symptoms. In these cases, eradicating the heat eliminates the problem. Some temperature-sensitive patients find that a cold bath may temporarily relieve their symptoms. For the same reason, swimming is often a good exercise choice for people with MS. (Wenzel) The erratic symptoms of MS can affect the entire family as patients may become unable to work at the same time they are facing high medical bills and additional expenses for housekeeping assistance and modifications to homes and vehicles. The emotional drain on both patient and family is immeasurable. Counseling may help MS patients, their families, and friends find ways to cope with the many problems the disease can cause. (Lambert) There is as yet no cure for MS. Many patients do well with no therapy at all, especially since many medications have serious side effects and some carry significant risks. (Health Central) Naturally occurring or spontaneous remissions make it difficult to determine therapeutic effects of experimental treatments; however, the emerging evidence that MRIs can chart the development of lesions is already helping scientists evaluate new therapies. Until recently, the principal medications physicians used to treat MS were steroids possessing anti-inflammatory properties; these include adrenocorticotropic hormone (better known as ACTH), prednisone, prednisolone, methylprednisolone, betamethasone, and dexamethasone. Studies suggest that intravenous methylprednisolone may be superior to the more traditional intravenous ACTH for patients experiencing acute relapses; no strong evidence exists to support the use of these drugs to treat progressive forms of MS. Also, there is some indication that steroids may be more appropriate for people with movement, rather than sensory, symptoms. (Mayo Clinic) While steroids do not affect the course of MS over time, they can reduce the duration and severity of attacks in some patients. The mechanism behind this effect is not known; one study suggests the medications work by restoring the effectiveness of the blood/brain barrier. Because steroids can produce numerous adverse side effects (acne, weight gain, seizures, psychosis), they are not recommended for long-term use. (Bernard) One of the most promising MS research areas involves naturally occurring antiviral proteins known as interferons. Two forms of beta interferon (Avonex and Betaseron) have now been approved by the Food and Drug Administration for treatment of relapsing-remitting MS. A third form (Rebif) is marketed in Europe. Beta interferon has been shown to reduce the number of exacerbation s and may slow the progression of physical disability. When attacks do occur, they tend to be shorter and less severe. In addition, MRI scans suggest that beta interferon can decrease myelin destruction. (Mayo Clinic) Investigators speculate that the effects of beta interferon may be due to the drug’s ability to correct an MS-related deficiency of certain white blood cells that suppress the immune system and/or its ability to inhibit gamma interferon, a substance believed to be involved in MS attacks. Alpha interferon is also being studied as a possible treatment for MS. (Mayo Clinic) Common side effects of interferons include fever, chills, sweating, muscle aches, fatigue, depression, and injection site reactions. (Health Central) Scientists continue their extensive efforts to create new and better therapies for MS. Goals of therapy are threefold: to improve recovery from attacks, to prevent or lessen the number of relapses, and to halt disease progression. In conclusion, MS is a disease that is well known but poorly understood by the medical and nursing community as well as the general public. It has no known cure and the genes that are accountable for it have yet been pin pointed. The United States is capable of finding a cure for this disease; over the years, medical researchers have found cures for many diseases that were thought incurable. Not only time and money are needed to find a cure for this disease, but faith and heart are needed to realize the importance.

Multiple Sclerosis

Multiple Sclerosis is a disease that disrupts information-flow between the body and brain, and also within the brain. It is a disabling, unpredictable disease that targets the central nervous system. Its cause is yet unknown and is assumed to be exposure to environmental factors, also unknown, to people who may react. The total number of victims are unknown but are estimated to be over two million world over. The unknown number of victims is because the symptoms may be completely invisible and because responsible bodies have not been required to register new cases.

The contraction of this disease is based on several risk factors the first of which is age. Studies on research data have shown that the age group of between fifteen to sixty have the highest likelihood of getting the disease. The other risk factors are gender, family history, certain infections, race, climate, lifestyle and certain autoimmune diseases. Lifestyle, smoking for instance, makes an individual to be more inclined to register the second series of attack on the central nervous system(CNS)(Weiner, 2005). These attacks are thought to be done by the immune system of the body that has lost some of its purpose of protecting the body(Phelps, 2010). Whilst both men and women are victims of this terrible disease, most of the cases have been registered in women. Women therefore, have been deduced to be more inclined to contract the illness than their male counterparts(Weiner, 2005). Through study on race and family history, it has been concluded that white people especially from Northern Europe or of this decency are more vulnerable. They have reported more cases unlike their Asian, African and Native Americans counterparts(Phelps, 2010). People who have type 1 diabetes, the thyroid disease, the inflammatory bowel disease, and other viral infections that have been linked to the MS are also more likely to develop it(Longnecker, 2008). The infections make patients susceptible to the symptomatic development of the Multiple Sclerosis. Climate is thought to affect the contraction rates as individuals from the more temperate regions have been affected a lot less than individuals from the colder parts of the globe(Longnecker, 2008).

The objectives/ aims and purposes of this study are highlighted in the following sentences. First, the resarch study aims to identify the target group/ the groups that have fallen more victims to MS. The second objective is to identify the typical symptoms of MS and the root causes of these symptoms. Thirdly, the study analyzes the fatality and effects of MS, the effectiveness of the diagnosis and available treatment.

Research Hypotheses

A hypothesis is a statement of investigation for a researcher. Usually, the development of a theory is based on an assembly of facts organized in an intricate pattern such that a relationship arises therefrom. The resultant theory has more meaning and is more concrete because it has its backing on substantial facts (Martin & Bridgmon, 2012). From that point, relationships that do not ackmowledge individual facts in a theory are examined. When doing this, the researcher normally has little knowledge of the correctness of the relationships he or she attributes to the facts. These formulated relationships are what make up a hypothesis. A verified hypothesis is sufficient ground to interpret a particular theory in the future. Essentially, the hypothesis is a predictor of something unknown (Martin & Bridgmon, 2012). Such prediction can be tested to ascertain whether it is valid. During such testing, the prediction may turn out to be in line with common sense. In the same measure, the prediction could turn out to be correct or incorrect. Overall, the testing is empirical. This means that the outcome is not necessarily important so long as it is an answer to the prediction. Overall, a hypothesis serves the function of relating different phenomena in some way to permit an empirical analysis of the same. This function calls for a research design that eventually proves or disproves the hypothesis based on the data gathered during the research (Martin & Bridgmon, 2012).

Hypothesis 1

Among people with multiple sclerosis, there is no difference in recurrent fall frequency with and without physical therapy.

Hypothesis 2

Among people with multiple sclerosis, there is a difference in recurrent fall frequency with and without physical therapy.

The research is also guided by the following thesis and antithesis.

Thesis: Physical therapy helps prevent recurrent falls in people with multiple sclerosis.

Antithesis: Physical therapy does not help prevent recurrent falls in people with multiple sclerosis.

The nature of this disease is not clear yet to scientists in this field. This research proposal examines some of the facts behind the MS and restates clarity.

The Background of Multiple Sclerosis

The first case of multiple sclerosis was registered in Rotterdam in the late 1300s on a woman who has been canonized as St. Lidwina. Through to the 1800s, no one understood really this disease. Over the years, individual cases of MS have been stated in great detail. Jean-Martin Charcot, the father of modern neurology, introduced the first cohesive perspective of MS in 1869(Longnecker, 2008). The diagnosis of MS is not easy but has been made simpler to technicians by introduction of technically advanced resources. Previously, there were no neurologists with the skill to carry out this diagnosis. At the moment, the FDA approved treatments for MS are six(Longnecker, 2008). There are also seventy new therapies at different stages of trial which will be tested at Stanford. There’s a Multiple Sclerosis center at Stanford that has a team of highly qualified neurologists offering a special diagnostics and treatment. The treatment offers comprehensive individualized care combined with great research opportunities. It also has access to clinical trials and state-of-the-art technology that include the electrodiagnostics and the Magnetic Resonance Imaging(MRI). It has services like immunology infusion, information on current treatment and research and follow-up services.

Early Signs and Symptoms of MS

It has symptoms that include optic neuritis(vision problem). In this case, an individual’s central vision is disrupted because of the inflammation of the optic nerve. The degenerative effect is slow so this makes the vision problem not be noticed immediately. The other symptom is numbness and tingling on the fingers, arms, legs and face. This occurs when the MS affects the brain and spinal column prompting them to send mixed signals(Longnecker, 2008). Involuntary spasms of muscles and chronic pain are also common occurrences. The condition also comes with knee jerking movements that are involuntary and extremely painful. The third symptom is unexplained weakness and fatigue that affects e80% of victims at the early stages of the infection(Weiner, 2005).. MS is also characterized by problems in balance coupled with dizziness. Also affecting an up to 80% population of total victims, problems with the bladder, bowls and sexual dysfunctions also characterize MS. The problems occur because most of these activities are controlled by the central nervous system that is attacked by the MS(Weiner, 2005). Problems with language, memory loss, shortened attention span and reduced levels of concentration mark another symptom. The cognitive malfunction affects at least half the total victims. Major depression and the pseudo bulbar affect are also common among people with the MS. Other symptoms may include seizures, memory loss, uncontrollable shaking, breathing problems, slurred speech and problems in swallowing(Longnecker, 2008).

There are mixed information on the group that is targeted by the Multiple Sclerosis. Whilst previously scientists still held on to the ground that it affects no particular group or race of the human, contradictory information and research have proven otherwise. Scientists have now observed that the Multiple Sclerosis is more common among people from Northern Europe, or of this line of decency(Weiner, 2005). They hold that it has become more common among the Latino or people with Latino backgrounds. Their research holds that people of African decency, Asians or Native Americans have the lowest risk. The findings of this research has a created a presumption that vitamin D plays a factor in the level of risk. People around the equator, who are exposed to more sunlight hence more vitamin D, have low levels of risk of contraction(Longnecker, 2008).

The MS is not easy to diagnose because the early warning signs are always not directly associated with it as they are also caused by other conditions(Weiner, 2005). Symptoms like poor vision and memory loss are often handled for what they are because MS tend to appear with different symptoms in victims. The MS is not easy to diagnose because it has no single tests. It also takes time because diagnosis can only be confirmed after evidence of at least two episodes of activities of the disease on the central nervous system(Longnecker, 2008). Despite all the challenges however, a series of technical advances have been made that make the whole process possible, though it still is gradual.

There are no death cases directly linked to the Multiple Sclerosis. The medication has also been considered very safe with mild side effects. Though conditions like severe pulmonary complications, severe sepsis and aspiration pneumonia may lead to death. Aspiration Pneumonia is a result of deposition of food and liquid particles in the respiratory tract as a result of difficulty in swallowing. Poor nutrition, decreased sensation, immobility/ inactivity and bladder incontinence may cause sepsis, especially if left untreated. The MS also limits an individual’s ability to exercise, weakens their muscles and make them vulnerable to other infections. It is the contraction of such diseases like cancer, heart complications and stroke that may lead to an individual’s demise. Cases of victims committing suicide to avoid the problems they are going through have also been reported. Multiple Sclerosis is therefore not directly fatal, but both the physical and mental conditions that come with it are what may be fatal(Longnecker, 2008).

The MS has no permanent cure and the only available treatments are control measures(Jelinek, 2010). A number of disease-modifying drugs have been proven to slow the progression of MS in some people. These drugs suppress or alter the activities of the body’s immune system and are based on the theory that the immune system attacks the myelin surrounding nerves. The drugs serve to reduce the development of new brain lesions and the frequency and severity of attacks like the convulsions. Early diagnosis is very important as it creates time to find the drug that a patient can use comfortably. It also helps in curbing the developments of the disease, by slowing its growth and advances from early stages.

The objectives that have been set for this research proposal serves to explain diagnosis and treatments for MS. They also examine vulnerability of some individuals and the environmental factors that propagate this disease.

The Conceptual Framework of The Proposal.

Multiple Sclerosis

Factors for InfectionSymptoms

environmental, diet, gender, geneticweakening of muscles, breathing problems, cognitive problems, balance problems, dizziness and fatigue

DiagnosisOther Infections

MRI, Cerebrospinal Fluid(CSF), Respiratory Pneumonia, Heart attacks

Evoked Potentials(EP)Sepsis

Treatment/ Control

Drugs-oral and injections(intravenous, subcutaneous, intrathecal)Therapy

This conceptual framework explains the relationship among the variables of the proposal. The independent variable is the factors for infection. It leads to infection and symptoms. The symptoms lead to diagnosis, other infections and treatment. Diagnosis, affected by symptoms, also lead to treatment and control.

Research Methodology

Introduction

This proposal identifies the target group of the proposal and the reasons for their high likelihood of infection. Research conducted on information throughout the years from the first case in 1300 to date have pointed to geographical locations among other factors. The other factors include lifestyle, genetically factors and climatic factors. The research points out that people from a place of high infection rate who move out before puberty reduce the levels of risks. Now whilst diet and lifestyle may be the same among different populations, factors like climate and family trees make others more susceptible to infections. Most cases of MS are not diagnosed early because of the less obvious symptoms. The proposal examines the symptoms and their relation to each other. It scrutinizes the irregular symptomatic infections because so far, to two known patients have suffered from symptoms at the same rate, stage and style. The symptoms are always bare, but there are no measures that can help medics diagnose MS. The only option is to wait for the second attack by the Ms on the central nervous system and this takes time. The time taken/ lost leads to further development of the Multiple Sclerosis yet the earlier its arrested, the better and more stable an individual’s condition remains.

The MS itself has proven to be controllable, but the diseases/ opportunistic infections that may set in as its result have adverse effects (Jelinek, 2010). Through therapy and administering of drugs, the adverse effect of the immune system on the central nervous system is reduced. This leaves the patient in a more stable state. But the problems it causes like weakened muscles lets in other infections like heart diseases. Patients diagnosed with Multiple Sclerosis leave in fear of these other infections than their primary health state.

The Study Design

This research proposal adopts a qualitative design. It examines whether physical therapy helps avoid recurrent falls among people with Multiple Sclerosis. Information about the subject were collected through questionnaires, interviews and observations. This is a narrative research that has focused on a particular individual. Data in this research have been gathered through the collection and study of his testimonials.

Intervention

Multiple Sclerosis lacks a cure but measures to control it have been implemented(Weiner, 2005). Drugs that target to reduce the activities of the immune system, which is believed to be the primary cause of the disease, have been invented(Jelinek, 2010). When the immune system’s activities that target the central nervous system have been reduced, the speed with which the MS advances is curbed. The other mode of intervention is through the Behavioral Intervention. This has been effective in improving depression, motor function as well as fatigue. It has the potential to modify the disease by ameliorating the symptoms.

The method of intervention recommended by this study is therapy. There are two kinds of therapy that have been employed in the intervention against Multiple Sclerosis. The first is Physical Therapy(PT). The Physical Therapy can be used to intervene on the following symptoms; fatigue, walking difficulties, weaknesses, poor balance/ fall risk. It can also be used to intervene on stiffness, spasms and spasticity, pain, tremor/ ataxia, sensory changes that include proprioception and decreased functional independence. The second is Occupational Therapy(OT). The Occupational Therapy can be used to intervene on fatigue, weakness, balance/ fall risk, stiffness, spasms, spasticity and cognitive changes. It can also intervene on reduced manual dexterity, pain, tremor/ ataxia and sensory changes that include proprioception(Jelinek, 2010).

The reason for choice of therapy is that unlike drugs and medication, it just do not try to stop the development of the disease. It makes an attempt at reversing some of the conditions. It recreates psyche where hope had been lost, serves to strengthen weakened muscles and encourages a victim to take on the conditions head on. Occupational Therapy does not let the victim mentally fall into a state of regression, instead it instills in him the confidence to fight back and hold on.

Study Sample

The study is conducted at The Walden University Department of Online Students Registered with Disability. The choice for Walden University is factored by the love for the students whose mobility have been impaired. It therefore has a wide base from which proper and detailed information on Multiple Sclerosis, the biggest cause for mobility impairment.

Sampling Strategy

There are four sampling strategies overly. They include simple random, systematic, stratified random and cluster sampling strategies. The strategy chosen for this study is the systematic in which the produced samples are treated as random. It addresses the following issues. The first issue is to get sincere respondents who can help avoid response bias. Response bias results when a respondent deliberately conceals information from the researcher for various reasons. The second strategy is to help avoid non-response especially when respondents fail to answer phone calls, turn up for meetings or fill questionnaires. The third strategy is to get detailed full-cycle information. Therefore, the respondents should be experienced and well versed with social and scientific factors on Multiple Sclerosis(Jelinek, 2010).

Sampling frames

A sampling frame is the list of all the intendeded respondents for a study(Sparks, 2010). It is a list or other device, that a researcher uses to define his population of interest(Douglas, 2011). The randomness of choice of sampling depends on the level of accuracy of information required by the study(Velma, 2009). The element is introduced by picking a random number from and with which the selection should be started and based. Its samples form a block sample frame. There are two kinds of sampling frames which are list and non-list. Rarely can a researcher get direct contact to the population of his interests. The researcher must therefore rely upon a sampling frame to create a representation of all the elements of the population of interest(Jerry, 2009).

In this study, one in every ten students will be chosen to form a list sample frame. The sampling strategy and the sampling frames give a total of three group samples/ lists for the study.

Allocation of Treatment Arms

The three groups are then subjected to the three different methods of intervention. Every is allocated a different method from the previous. The purpose of different allocation is to verify/ compare the efficiency of each of the three intervention techniques to Multiple Sclerosis. The first group, marked as I, is subjected to medical intervention. The second group, marked as II, is subjected to the behavioral intervention. The third group is subjected to intervention by use of therapy, this group is christened group III.

The study variables

There are three variables for a research study. These are the dependent, independent and the confounding variables. The validity and reliability of a research study is increased when the variables are controlled by ensuring that the causal effects are eliminated(Jerry, 2009). It is also known as isolation of the independent variable. The process of isolating the independent variable, involves changing the other variables into consonants. Eradication of the research variables involves employing scientific measurements to negate or nullify them(Velma, 2010).

The research study on Multiple Sclerosis will have two variables that will govern the style of research after the conversion of the variables of research into constants. They include the independent and dependent variables. The independent variable of the study is physical therapy whilst the dependent variable is the falls in people with multiple sclerosis. This study does not bear a confounding variable.

Methods of Data Collection

Though a part of the research is observational, most of the data collection is conducted through survey. Methods like the use of questionnaires and interviews are employed. The reason for survey is to improve the level of communication with the respondents to get even their personal information. Survey improves precision and clarity of information as no research content is based upon assumptions. Questionnaires are distributed to the respondents/ members of the sample frames/ groups. The best response is then picked from the questionnaires once they have been submitted by the respondents. The respondent who filled the questionnaire is visited for an interview. The process is tedious but very effective.

Data Management

Data management is the manner in which data collected from a study is handled to serve the purposes of the study and also serve as a base of reference for future studies(Jelinek, 2010). When done effectively, data management helps in achieving clarity and cohesion of a research and study and intended future studies as well(Jerry, 2009). There are set procedural and order/ steps and guidelines for Data Management. The first is data collection from the recipients, then Data maintenance, storage, validation/ correction and manipulation(Jerry, 2009). The steps before precede data views, access, security and documentation(Jelinek, 2010). To achieve a high level of efficiency, this research study aims to follow the data management protocol.

Data mangement will be conducted is described in the paragraph herein. The recipients mail back their responses/ questionnaires. The questionnaires are then filed according to the samples/ groups that had earlier been set and marked as I, II and III respectively. The collected data is then validated and corrected to comply with the scientifically facts. Responses based on mythical theories without a scientific support are cancelled. The data is then extracted and changed into essays. The process of extraction is also known as Data Manipulation and Reporting.

The views and responses of the data must be clearly outlined in the essay. Relevant explanations are given where necessary to give clarity and make observational references. The data of this research findings should be made accessible to researcher’s and victims for future references. To make this easier, there should be hardcopies of the findings in the order of educational journals. A report on the data is also made as part of the documentation procedures.

Data Analysis

The aims of this research are to determine the number and incidences of MS patients with fall incidences while analyzing the effects that the condition has on the patients’ life, work and education

The paper also examines the effectiveness of the PT and OT in slowing down the advancements of the disability and reducing the frequency of falls . The General Practice Research Database and Hospital Episode Statistics data (Creswel, 2014) is the preferred method of data analysis for this study. Based on patient records and hospital intervention, the two methods will enable accurate compilation and analysis of data.

General Practice Research Database (GPRD)

The calculations on the follow up durations per patient are done annually to determine the fall incidences of patients per year and whether a diagnosis has occurred due to such falls (Carlin & Louis, 2008). The fall incidences will be estimated using passion regression models with logarithm (time at risk) as the offset variable (Martin & Bridgmon, 2012). The gender analysis is done separately and year and age are used as the variables for the models.

Hospital Episode Statistics (HES)

The available HES data for the patient population will be analyzed. Estimates of fall incidences within the time duration will be made using the GPRD data (Ott & Longnecker, 2008). The fall incidence rates will then be calculated using extra diagnosis from HES. Age-specific rates of fall incidence will be estimated from inverse polynomials and fitted to ratio cases from GPRD and HES versus GPRD alone (Creswel, 2014).

Dissemination of Research

Victims of Multiple Sclerosis are the main stakeholders in this research proposal. They are the focal point of the research. Because of their immediate contacts with the MS patients, the families and friends have information on the effects of this disease. The information that is firsthand, especially on the falling incidences and they should be handled is vital to the research(Martin & Bridgmon, 2012). For this reason these family members will also be part of the processes of the research. Research institutions that include health facilities and professionals, schools and their staffs and members of the community also play a vital role as stakeholders in this research. The reason for this is that they are privy to information on research and challenges faced by the victims of MS.

There is a need and necessity to formulate Government policies galvanizing the education and employment of MS patients. The victims always get victimized and discriminated against because of their sluggish movements and mobility problems. For this reason, Government representatives will also take part in the research. The media will also take part as the issue of MS fall incidences is a serious issue that should attract public awareness (Jelinek, 2012). They not only come to create awareness on the fall cases and reasons for fall, but also to decampaign the discrimination against the MS patients. Lastly, the research will source for sponsors who will also become part of the project to evaluate its progress and look into matters of transparency and accountability.

Ethical Issues

Physicians assert that in cases of probable diagnosis, at the early stages before the second attack on the CNS, patients should not be informed of the contraction of the disease. They base this on the argument that a medic’s first role is not to create panic but to relieve patients of pain (Phelps & Hassed, 2012). Telling patients the truth, they argue, could trigger mental agony rather than give patients a piece of mind. Justification for this is that the early phases of MS do not exhibit serious falls. Moreover, it is hard to precisely predict future experiences (Phelps & Hassed, 2012). Most patients will not understand anything about such future experiences.

Respect for persons calls for voluntary informed consent plus adequate patient information regarding the research aims, procedure, methods, potential risks and anticipated benefits (Phelps & Hassed, 2012). Patient autonomy is a very crucial principle – patients should be allowed freedom of expression, comment and adjustment as the research progresses. Moreover, when analyzing the benefits and risks of the research, they should be weighed critically based on the potential benefits of new interventions against the current ones (Phelps & Hassed, 2012). Lastly, justice should prevail when selecting the participants in the research. There should be no reasons other than ethical or scientific ones for including participants into the research.

The need to source for funding makes it necessary to seek IRB approval. The IB approval only comes when the validity of the research is clearly stated and emphasized. This research has its relevance steeped in the statements that follow. It articulates the woes and tribulations of the MS patients at school, work and even in their everyday life. Policy statements have been slow to capture the problems faced by the victims of MS. The key factor for this is that the research and reports made about this filed have not been sufficient. The research findings of this proposal therefore will serve to enhance policy development and create awareness concerning Multiple Sclerosis.

Secondly, assurances on the respondents/ participants ‘safety throughout the research have to be paramount. The research aims at participation of MS patients and other stakeholders at free will. During the research, measures to control and lessen any jeopardy/ risks of harm that might suffice during the research will be put in place. Moreover, there will be an efficient consent procedure whereby no participant feels compelled to take part in the research. In addition, withdrawal decisions will be honored. Lastly, before seeking IRB approval, the respondents’ perceptions on the research will be clarified.

Chapter 10 Reflection- Feminism

Even though women were not highly involved in issues to do with criminal justice during the 1970s, they began to get highly involved in this field. Feminist theories are considered to be part of conflict theories. They came around during the 1970s when conflict explanations were popular and focused on conflict perspectives and male-based theories. There was a need for equity and equality in terms of treatment at home and work regarding crime. Before the onset of feminism, theories concerning criminal justice women were rarely brought to courts unless they did something huge. However, in the desire to be more like men and have an equal share in society, they began being apprehended for their crimes. Therefore feminism theory is an example of conflict theory. One gender of a society is considered weak, and there is a lack of equity and justice based on gender.
