Music falls Essay Example for Free

Music falls Essay This third activity was chosen because it provides the children with this means of communication, giving them the opportunity to express themselves freely. Doing this helps them progress emotionally and cognitively in all other areas of their learning. Music falls under Donaldsons construct mode, under value-sensing. She argues that emotion and thought are frequently related closely to one another (Palmer, 2001).  Neill (1927) also favoured music within the curriculum, as he alleged that it had a therapeutic function, particularly with children with psychological problems. He also acknowledged that it gave the less academically challenged pupils something they may excel at. This activity, therefore, assists in increasing the childs self esteem, giving them more confidence in other areas of the curriculum too. Differentiation  The possibilities for differentiation within this lesson are extensive. As it is a relatively free activity, the children can move as much, or as little as they like. Interaction from the practitioner could be by means of praising those who demonstrate effort and capability, or by encouraging the children to express themselves and by giving them the confidence to move as they wish. Those who do not attempt to join in could be partnered with others, to provide further encouragement and enjoyment. Evaluation  This activity provides the children with the freedom to move their bodies in ways which are normally considered inappropriate within the classroom. There is no specific way in which the children are required to move and so they have the opportunity to truly express themselves without the usual confines and barricades. Skinner (1971) believes that behaviour is not something a child is born with, it is shaped by consequences. The conditioning adopted by the setting determines the catalogue of behaviour the child has at his disposal (cited in Palmer 2001). Skinner recognised that children respond to positive re-inforcement. The practitioner in this activity praises the children, encouraging them to express themselves further. Bandura suggests that adults can gain childrens attention and highlight the behaviour patterns they want to encourage (David T et al, 2003). He suggests that the children will mimic the behaviour they see in others. In this activity, if the children see the practitioner praising one child as suggested by Skinner, their behaviour will be reinforced and this should encourage more of this behaviour. As the rest of the children bear witness to this development, Bandura suggests that they will reproduce this behaviour to gain recognition for themselves. This was apparent when watching the behaviour of the whole class. When one child became slightly over-excited and silly, others began to imitate him. The practitioner quickly took control of the situation by praising one of the children who was making slower, more gentle movements and the children responded swiftly by slowing their movements down too. Conclusion Each one of these activities proved to be successful. The children enjoyed them and were keen to stay on task throughout. The relevant areas and aspects of learning were adequately covered and the children gained a great deal from participating. From carrying out this research, it is apparent that it is necessary for practitioners to plan their scheme of work effectively in order to guarantee that the foundation stage curriculum is covered throughout the year. This work has examined the long, medium and short term plans and has explained why they are used. It has researched the emergence of the foundation stage curriculum and the ways it can be adapted and moulded to fit into many different types of early years settings. Using the three activities this work has established the theoretical underpinning of the curriculum and demonstrates the strategies which can be applied to differentiate the experiences effectively.

The Anglo-Saxon Period Essay -- essays research papers fc

The Anglo Saxon period is the oldest known period of time that had a complex culture with stable government, art, and a fairly large amount of literature. Many people believe that the culture then was extremely unsophisticated, but it was actually extremely advanced for the time. Despite the many advancements, the period was almost always in a state of war. Despite this fact, the Anglo-Saxon period is a time filled with great advancements and discoveries in culture, society, government, religion, literature, and art. The Angles were a Germanic tribe that occupied the region which is now Scleswig-Holstein, Germany. With their fellow ethnic groups, they formed the people who came to be known as the English. The Saxons were a Germanic people who first appeared in the beginning of the Christian era. The Saxons were said to have lived in the south Jutland Peninsula in the north of what is now Germany, but the fact has not been proven. They attacked and raided areas in the North Sea throughout the third and fourth centuries. By the end of the sixth century, the Saxons had taken all of the Roman territory within north-west Germany, as far as the Elbe River. The Angles joined the Saxons in the invasion of Britain in the fifth and sixth centuries. British resistance to the 'Anglo Saxon' invaders in the second half of the fifth century ended with the Anglo Saxon’s victory at the battle of Mount Badon. After the British were defeated, though, the Angles and the Saxons continued to fight over their re ligion for many years (Irvin, Vacca, Probst, Beers, p.46). Before the year 596, almost everybody had strong pagan beliefs. In 596 missionaries had begun to attempt to convert the Anglo-Saxons to Christianity. By the year 650, almost all of England had converted to Christianity- at least in name. Although almost everyone claimed to be strong believers in Christ and the church, most still held on to their pagan beliefs and traditions. No matter what they believed, everyone applied their religious beliefs to their everyday life. (Chin et al. Glencoe Literature, p.35). Everyone in the age would always wear extremely modest clothing. The common garment for a man was the robe gathered at the waist, completed by hose and soft sandals. The same was for the woman, except their dress extended to the feet. The most common materials used to make clothing were linen and woolens, though... ...nbsp;  Ã‚  The technological advancements and discoveries of the Anglo-Saxon period set the stone for today’s society. The age had all of the parts of their culture that we have today. Their period set the foundation for art, society, literature, and culture of what we have today. America would be a very different place if it was not for the impact that the Anglo-Saxon period had society.   Ã‚  Ã‚  Ã‚  Ã‚   Bibliography 1.  Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Anglo Saxon Art†; The Hutchinson Book of the Arts .

Preventing Alzheimers Disease Health And Social Care Essay

Alzheimer ‘s disease is a disease named after Alois Alzheimer who foremost described it in 1906. It is besides known as Senile Dementia of the Alzheimer Type or Alzheimer ‘s and is the most common signifier of Dementia. It is an incurable, degenerative and terminal disease and is normally diagnosed in people of over 65 old ages of age, nevertheless, there are hints of its oncoming in much earlier ages ( Wegesin & A ; Stern, 2004, p.646 ) .The 2006 statistics indicated that 26.6 million people suffered from this disease universe. The common symptoms for this disease are thought to be age related concerns or emphasis manifestations. The disease is characterized by memory loss, such as trouble in retrieving late learned facts in earlier phases and confusion, temper swings, linguistic communication dislocation, crossness and aggression and general backdown in the advanced phases. The causal effects for this disease are still unknown with fingers indicating to plaques and tangles in the encephalon. Most interventions available for this disease offer diagnostic benefit but fail to turn to the hold or patterned advance of the disease. Since it ‘s incurable and degenerative, the direction of patients is indispensable. The disease is known to put a great load on health professionals who experience psychological, economic, societal and physical force per unit areas while taking attention of sick person ‘s of this disease. This disease is one of the most dearly-won diseases in the developed universe. GuideAge Study: Test of EGb 761 for bar of Alzheimer ‘s disease among the aged with memory ailments. The primary aim of the survey was to find the consequence of EGb761 in intervention on the rate of transition from memory ailments to Alzheimer ‘s disease utilizing survival analysis. The chief marks for this survey were ambulatory patients aged 70 old ages who exhibited memory ailments during a GP or memory centre audience. Those with nonsubjective memory damage or clinically relevant symptoms of anxiousness and depression were nevertheless excluded. Participants were so required to do one-year visits to a memory centre where a series of neuropsychological trials were conducted to measure the cognitive map and cognitive position. The functional position was evaluated with the Instrumental Activities of Daily Living Questionnaire ( Andrieu et. al. , 2008, p.406 ) . The survey recognized that primary and secondary bar schemes are desperately needed for Alzheimer ‘s disease as its prevalence continues to lift in industrialised states, with statistics demoing that it has presently affected over 24 million people worldwide. There is besides a high load associate with this disease. The schemes have ab initio proved to be effectual in cut downing mortality, morbidity, and wellness attention costs. Available interventions better cognitive symptoms and estrogen or satin related interventions are secondary bar schemes for Alzheimer ‘s disease ( Wegesin & A ; Stern, 2004, pp.647-648 ) . The basic scientific discipline and clinical informations indicate that estrogen therapy permeates healthy nerve cells with a survival advantage when challenged with a neuro-toxic agent. Greater benefit would hence be predicted if estrogen therapy is begun while nerve cells are still healthy and non biologically compromised ( p.650 ) . The estrogen advantage to healthy nerve cells provides plausible account for why estrogen can be good in forestalling neurodegenerative diseases such as Alzheimer ‘s ( Brinton, 2004, p.419 ) . In add-on, in the intervention of AD, randomized placebo-controlled surveies have provided grounds of efficaciousness. The survey was spread out in a five twelvemonth program, and the primary aim was to find the consequence of intervention with EGb 761 on the rate of transition from memory ailments to dementia of Alzheimer type utilizing survival analysis. The survey design: incorporated a web of doctors to enroll topics ; the eligibility standard was validated in one of 25 mention memory centres. Coordination was by the infirmary mention centre located in Toulouse France ( Andrieu et. al. , 2008, p.407 ) . Age, residential location of patients, mean socio-cultural and instruction degrees, and self-generated coverage of memory ailments were the chief considerations for patient eligibility. Ocular sharp-sightedness and presence of drusen, unnatural pigmentary epithelial tissue and vascularization were considered in the diagnostic standards for age related muscular devolution. Apolipoprotein E, a genotypic determiner for intervention response was taken from blood samples while urine samples were taken to find isoprostan, a possible biochemical alternate marker of result. Spontaneously reported inauspicious effects were recorded for safety rating intents ( p.407 ) . In the intervention procedure, topics were randomized at the proof visit by having EGb 761 or a duplicate placebo. Blinding was ensured by indistinguishable visual aspect of placebo and active drug while colour marker was ensured by utilizing a brown pigment. Behavioral appraisal was through the disposal of neuropsychological trials for appraisal of cognitive map ; the cognitive position was besides evaluated blending MMS and CDR ; Functional position was evaluated utilizing the Instrumental Activities of Daily Living Questionnaire. Other appraisals involved balance perturbations, assessed by finding one ‘s ability to stand on one leg, posturography and diagnostic standards for sarcopenia ( pp.407-409 ) . Outcome steps entailed independent adjudication by four clinicians non connected to the survey to determine unvarying instance consequences. Changes in CDR dementedness tonss and alterations in public presentation on neuropsychological trials were considered in the secondary result steps. The study described the cognitive map and disablement in a population composed of 2854 patients who complained of memory jobs. These patients were younger and better educated with high MMSE tonss and longer continuances of memory ailments. Primary attention was the chief context of the survey. Patients who exhibited dementedness, anxiousness and depression symptoms were besides excluded from the survey so as to enrich the survey sample in patients whose memory ailments were related to underlying cognitive troubles other than emotional influences. From the screened population, over 60 per centum scored 0.5 or more on the Clinical Dementia Rating Scale therefore a comparative grade of cognitive damage was recognized. This hence supported old findings where bulk of patients reported ailments in the general population therefore grounds of convergence between aged patients with subjective memory ailments and those with nonsubjective steps of cognitive damage ( p.410 ) . The consequences hence imply that many aged individuals with cognitive damage are undiagnosed within the community and that a pro active attitude from practicians would assist place such people and pave manner for proviso of appropriate attention. CDR would besides be concluded as a sensitive agencies of observing cognitive damage amongst the aged. TheGuideAge is an of import and advanced tool for bar of AD in Europe. A recent survey provided grounds of Gingko biloba infusion effectivity in forestalling cognitive diminution in aged individuals. To farther find the efficaciousness of Gingko biloba, the GuideAge survey provided the needed informations from a big figure of topics. It would besides be effectual analyzing the development of cognitive map and see hazard factors as forecasters of transition from memory ailments to AD in the population. From this analysis hence, it can be concluded that preventative steps for AD are executable owing to the ability to obtain informations every bit good as initiate drug usage in a big sample of the population. Preventing Alzheimer ‘s disease: fact or fiction The prevalence is Alzheimer ‘s disease is significantly increasing in the United States. Presently, the population of those with this disease stands at 4.5 million with an estimated addition of between 11 and 16 million in the following 50 old ages. In add-on, explosive alterations in engineering would ensue in a great challenge in reflecting the mildest signifiers of cognitive shortage. The starchlike plaque in the encephalon remains the trademark pathology of Alzheimer ‘s disease and the amyloid cascade, provides marks for intercessions. The chief purpose of the intercessions is to cut down harm ensuing from starchlike plaque load ( Grossman & A ; Dyk. , 2008, p.887 ) . Significant positive attacks have been made, polar to the designation of diagnostic intervention of Alzheimer ‘s disease and the designation of conditions associated with increased intervention hazards. The success of true bar is nevertheless considered every bit fabricated as there is less informations to back up the claim that the aforesaid hazards cut down the incidences of AD. Several advantages can be drawn from concentrating on the bar of the disease ; foremost, it would spread out the period of high quality of life in aging populations, a hold of oncoming of the disease by one twelvemonth would significantly cut down its prevalence rate, and costs associated with the disease would be minimized ( Grossman & A ; Dyk, 2008, p.888 ) . Despite advancement in the decrease of the disease, bar schemes are still in the grapevine. Medical intercessions for this disease are characterized as primary, secondary and third. Primary: focal point on disease bar ; secondary: on decrease in morbidity in preclinical persons: and third, on remedy, palliation and rehabilitation. Grossman & A ; Dyk ( 2008 ) acknowledge that current therapies for Alzheimer ‘s disease do be. Tacrine was approved in 1993 by the US FDA as the first intervention for AD. The bureau besides introduced donepezil, rivastigime and galantamine as other intervention drugs. They further discourse that primary bar refers to the bar of disease in an unselected population tests to this demand to inscribe a big figure of topics with few exclusion standards and infuse simple cheap ratings of results, with long observation and monitoring periods. The length of clip for bar tests and topics ‘ registration, consequence into high disbursals therefore a substi tution of the bar test, the ‘add on ‘ protocol permits the ratings of multiple spheres in a individual clinical test cohort ( p.900 ) . Both primary and secondary bar tests require careful attending to safety. The agents selected for bar surveies are often referred to as ‘neuroprotective. ‘ A term used to distinguish agents expected to cut down cognitive diminution instead than alleviation of symptoms. Preventive mechanisms purpose at cut downing starchlike plaque by changing metamorphosiss or protecting cells from starchlike toxicity. These mechanisms are largely proposed based on research lab and carnal surveies as few markers of biological mechanisms available in worlds exist. Several categories of agents with encouraging consequences have been tested. These are clearly discussed below. First of all, lipid-lowering medicines, the HMG-CoA reductase are known to impact greatly on knowledge, dementedness and Alzheimer ‘s disease by cut downing cholesterin degrees in the organic structure of worlds ( Sparks et. al. , 2008, p.418 ) . Second, tramiprosate, a 3-amino-1-propanasulfonic acid ab initio developed as a pharmaceutical intervention was examined in a two phased survey of 58 patients with mild to chair Alzheimer ‘s disease over three months. Patients having tramiprosate experienced a decrease in Alzheimer ‘s. Neurochem subsequently reported that tramiprosate would be used as a nutraceutical. Third, immunotherapy initiated by utilizing filaments for the development of Alzheimer ‘s vaccinum was addressed in Schenk ‘s 1999 study as an option for regressing starchlike plaque. There was grounds of a patient showing clearance of AI? hint sedimentations from their cerebral mantle, and a significant microglial response. It was further conclude d that supplanting of AI? , even when embedded in plaques, is possible in worlds when immunotherapeutic techniques are used. Third, is the usage of enzyme inhibitors. Amyloid plaque remains a trademark pathology for Alzheimer ‘s with the amyloid cascade supplying marks for intercessions to assail implicit in mechanisms. Therefore, intercessions to cut down the amyloid plaque load are widely proposed. Furthermore, the control of high blood pressure is grounds associated with decreased hazard of cognitive damage and dementedness, features of Alzheimer ‘s. Some surveies have shown that effectual control of high blood pressure is associated with cognitive benefit. Hormone replacing schemes are besides seen as good mechanisms for the bar of Alzheimer ‘s. There is an feeling that estrogen may be good in keeping cognitive map and detaining dementedness. The benefit of estrogen accrues from the fact that the endocrine acts as a neurotrophin in the pyramidal cells of the CAI part which is known to devolve in Alzheimer's.Astrogen protects the hippocampal nerve cells therefore reduces nervous AI? coevals. Antioxidative schemes on the other manus employ the fact that oxidative emphasis plays a important function in aging and Alzheimer ‘s disease. The usage of antioxidants such as Vitamin C and E is associated with the decrease of hazard of dementedness. Nutritional supplementation, considers that dietetic and nutritionary addendums have an consequence on the hazard of Alzheimer ‘s. From several surveies conducted, the usage of Ginkgo biloba, a herbal addendum indicated an betterment in knowledge. Another clinical test on Salvia officinalis was studied for its possible benefit on knowledge in patients diagnosed with Alzheimer ‘s. Significant benefits were discernible between the end point and baseline tonss on cognitive steps of the intervention group compared with the placebo group ( Doraiswamy, 2002, p.816 ) . Last, nonpharmacological intercessions such as physical exercising are observed as options to protect the aged from cognitive diminution. A Meta analysis conducted reported benefits from physical exercising on functional public presentation, behaviour and knowledge steps in patients with cognitive damage and dementedness. The execution of Cognitive Motor Interventions on 38 patients in one twelvemonth which involved cognitive exercising, societal and psychomotor activities indicated an betterment in temper and subsequent tonss against a control group ( Kreil et. al. , 2010, p.17 ) . Alzheimer ‘s disease is a common wellness concern amongst the aged. While effectual intervention is available, the bar mechanisms are non yet good understood. Cholesterol lowering, other cardiovascular hazard decrease, starchlike metamorphosis and antioxidant mechanisms every bit good as environmental sweetenings have proved as plausible bar options ( Doraiswamy, 2002, p.818 ) . Evidence-based Approaches to Preventing Alzheimer ‘s disease. Non modifiable hazard factors for Alzheimer ‘s include: Age ; this remains as the strongest hazard factor for dementedness, peculiarly for Alzheimer ‘s. The hazard doubles every five old ages in persons above 65 old ages. The hazard nevertheless increases by stopping point to 50 % after 85 old ages. Family history ; hints of Alzheimer ‘s in households ‘ histories for 5 % or less of instances. Hereditary or environmental factors related to households are major influences of this disease. Familial factors ; early Alzheimer happening before 65 old ages histories for 6-7 % of all Alzheimer's.13 % of these clearly exhibit autosomal dominant transmittal over more than one generation.30-70 % of mutants are in presenilin-1 cistron, 10-15 % are in the amyloid precursor protein cistron, and less than 5 % are in the presenilin-2 cistron ( Bassil & A ; Grossberg, 2009, p.30 ) . Modifiable hazard factors on the other manus include cardiovascular hazard factors such as high blood pressure, diabetes mellitus, lipemia, intoxicant, depression, metabolic syndrome, smoking among others ( Bassil & A ; Grossberg, 2009, p.31 ) . From surveies conducted, the consumption of lipid-lowering medicines indicated a decrease in dementedness ( Sparks, 2008, p.419 ) . Other possible helpful agents to forestall Alzheimer ‘s include: Antioxidant vitamins, the encephalons of Alzheimer ‘s patients contain lesions typically associated with free extremist exposure every bit good as elevated degrees of endogenous antioxidants. Antioxidants cut down the toxicity of AI? in encephalon surveies of Alzheimer patients. This therefore laid a footing for the appraisal of the function of antioxidants such as vitamins E and C and curcumin for the bar of Alzheimer ‘s. Curcumin has anti-inflammatory, anti- amyloid and antioxidant belongingss and is every bit a promising agent i n the bar of Alzheimer ‘s from the ascertained informations ( Bassil & A ; Grossberg, 2009, p.32 ) . Fish and Omega-3 fatty acids. Surveies have shown that consumption of concentrated fat, entire fat and entire cholesterin addition the hazard of dementedness. Reduced degree of Omega 3 fatty acids has been linked to increased hazard of dementedness therefore high fish ingestion would change by reversal the tendency in hazards related to dementia and cognitive diminution ( p.33 ) . Consequences form a community based survey affecting nondementaited persons indicated that attachment to a traditional Mediterranean diet was associated with important decrease in the hazard of incidents related to Alzheimer ‘s disease. Fruits and veggies are besides associated with improved cognitive public presentation in aged individuals. Fruits are particularly linked to decrease in dementedness. Some surveies have nevertheless associated high ingestion of veggies with decrease in cognitive diminution ( p.34 ) . Datas on intoxicant usage and cognitive map in the aged draws assorted consequences. The complexness in these consequences is brought approximately by the dose and type of intoxicant taken. The moderate ingestion of vino is associated with decreased hazard of dementedness and Alzheimer ‘s disease. On the other manus, high ingestion of intoxicant which consequences in alcohol addiction may take to cognitive diminution ( p.34 ) . A randomised controlled test late showed that moderate sums of intoxicant may detain age- associated cognitive diminution. Others include ; caffeine consumption, endocrine therapy, NonSteroid Anti-Inflammatory Drug ( NSAID ) therapy and homocysteine ( Ho et. al. , 2008, pp.86-88 ) . From this information it can be concluded that, dementedness is the consequence of a set of implicit in pathological procedures, some which are preventable. Familial factors, age and household history are disclosed as the major non-modified hazard factors while modified hazard factors range from alcohol addiction, high blood pressure, and diabetes mellitus to depression. All this contribute to the development of Alzheimer ‘s and plausible preventative solutions are hence obtained from these jobs. In add-on, familial exposure is seen to modify most of the hazards associated with Alzheimer ‘s. Although there is deficient grounds to cement primary bar recommendations on dementedness, doctors may recommend taking actions such as take downing cholesterin, blood force per unit area and homocysteine degrees and commanding diabetes. Three constituents of life style, that is, societal, mental and physical are associated with a brilliant decrease in the hazard of dementedness, and Alzheimer ‘s disease. Population based longitudinal surveies have supported the hypothesis that societal, cognitive and physical activity are reciprocally associated with the hazard of dementedness, Alzheimer ‘s disease and cognitive damage. Physical exercising has been thought to heighten encephalon neurtotrophic factors and modify programmed cell death. Dementia is lowered by continuing musculuss mass every bit good as forestalling falls and attendant caput injury ( Kreil et. al. , 2010, pp.18-19 ) . Evidence further shows that exercising can continue optimum cardiovascular map, better regional intellectual blood flow and deter shot and micro vascular disease. NSAID therapy involves the intervention of Alzheimer ‘s with anti-inflammatory agents which slow the patterned advance of dementedness and suppress its oncoming. NSAIDs portray increased possibilities of take downing degrees of amyloidogenic AI?42 protein ( Bassil & A ; Grossberg, 2009, p.35 ) . From the above information, it is deserving observing that Alzheimer ‘s disease can be prevented utilizing both pharmacological and non-pharmacological options. The integrating of dietetic options and physical exercising may besides be efficient in accomplishing the preventative end of Alzheimer ‘s disease.

How The Strength And Bmd Is Maintained - 1531 Words

How optimum bone strength and BMD is maintained Bone remodeling is a five-stage process. Bone is renewed to prevent accumulation of micro-damage and maintain bone strength and BMD (Burr, 2002) (See figure1): 1. Alteration in mechanical loading and micro-fracture is sensed by osteocytes. In response, bone-resorbing factors are released, activating bone-lining cells, which interact with pre-osteoclasts. The interaction stimulates pre-osteoclasts fusion and differentiation into multinucleated osteoclasts (Rucci, 2008) 2. Osteoclasts secrete matrix metalloproteinase and hydrogen ions via ATPase proton pumps into the area being reabsorbed, in order to lower the pH and digest the organic matrix. The osteoclasts then undergo apoptosis 3. Resorption ceases as mononuclear monocytes and macrophages replace osteoclasts to remove debris (Eriksen, 1986; Joseph Berstein, 2014). 4. Pre-osteoblasts are recruited by cytokines: transforming growth factor beta, insulin growth-like factors, fibroblast growth factors and bone morphogenetic proteins (BMPs) (Hock et al, 2004). The actions of BMPs cause pre-osteoblasts to differentiate into osteoblasts (Monolagas, 2000). Osteoblasts then secrete bone matrix proteins: type-I collagen, osteocalcin, proteoglycans, growth factors and glycoproteins into the resorption pits (Nair et al, 1996). Approximately 50% of osteoblasts then undergo apoptosis and the remaining become embedded osteocytes or bone lining cells. 5.
