An aging population Essay Example for Free

An aging population Essay Factors such as an aging population, technological advances, and the advent of managed care have indeed changed the way health care is being offered and is being perceived in the United States; for one, having an aging population means that the demand for nurses has increased.   Another impact is that of certain technological advances which make it easier to give healthcare at a more affordable rate.   In light of managed care and these other factors, much more is also required of a nurse aside from the standard of health care that was previously provided. Given the level of competition in this field and the increasing demands for highly specialized and trained nurses, I feel that the only way to continue my career in nursing is by being able to earn a bachelors degree in nursing.   More and more job opportunities these days require a minimum of a bachelor’s degree in nursing. While all of these technological advancements in health care have indeed raised the standard of health care being provided in the United States, there are a few intangible factors that can never be replaced.   I see my future role as being able to develop these intangibles.   One important example is the special type of manner by which a nurse must conduct herself in order to be effective in performing her task.   The bedside manners are very important and it is something that just cannot be taught in classrooms.   Nurses need to be more than just machines that come in and punch in their time cards but rather professional registered nurses who show their passion and dedication to the profession through their approach and practice There will always be future developments in technology and there will always be an aging population.   The key to succeeding in this profession is in maintaining the level of professional conduct that people expect from the nurse and this is the future role that I see myself in the profession of nursing.

Special Needs Children in the UK

Special Needs Children in the UK Special Needs Children Introduction The essay will examine a number of polices and initiatives that have received attention from the UK government. There have been changes in the policies surrounding the country’s curriculum. Issues surrounding this policy reform will be examined in detail. Current trends in education policy have promoted inclusion. This means that children with special needs have been incorporated into mainstream classes. Post compulsory schooling is also top on the education agenda. Besides this, recent education policy has been surrounding issues of school’s marketability. All these issues will be examined and the subsequent impact of those policies given. (Besley and Ghatak, 2003) Inclusion of special needs children Before the introduction of polices around this area, there was an eight year old girl; Victoria Climbie who died under mysterious circumstances. There was therefore a need to make sure that interests of all children were safeguarded regardless of their nature. (Gipps and Stobart, 1997) The main Act passed surrounding the issue of inclusion was the ‘Every Child Matters Policy’ in the year 2004. The purpose of this Act was to ensure that all the children in the UK were adequately encompassed in the education regardless of the fact that they had special needs. It was passed with five aims; Protecting the social and economic well being of the child Ensuring that all children contribute positively to society Ensuring that children received enjoyed good health Ensuring that children were safe Find out how our expert essay writers can help you with your work The spirit of the Act is that most children should have the opportunity to learn together whether or not they have disabilities. Most of them had been placed in special schools where they were rather isolated. Most of them lacked the ability to socialize and fit into the rest of the world. But through inclusion into mainstream schools, children with special needs have been able to improve their social skills. Psychologists also claim that a mixed environment is more conducive for children’s learning rather than when they are isolated. Their self esteem also receives a boost because thy feel that they are good enough to learn with other children.(Blanden Gregg and Machin, 2005) Benefits of inclusive education are not only felt by those children with special needs alone, they are also beneficial to normal children. This is because they learn that children with special needs are not so different from them. It eliminates the fears and stereotypes that come are associated with special needs children. (Gipps and Stobart, 1997) However, there is a need for teachers to prepare well for these special needs children. Failure to do so will result in poor adjustments by the child and surrounding classmates. It is also the responsibility of all stakeholders in the field of education to readjust their systems such that children with special needs can fit in well. It has been emphasised time and time again that mainstream schools should not expect children with special needs to adjust to their programme. Instead, the opposite should occur.(Machin and Vignoles, 2004) This policy has increased the availability of resources towards the education of children with special needs. It has also exposed children with special needs to better teaching facilities and skills. Consequently, it has improved their performance and contributed to the attainment of their potential. (Besley and Ghatak, 2003) Marketability in schools In the early nineties, it had been found that most children above the age of sixteen had low retention rates. This normally applied to those who came from low income households. Most of them would drop out and join the market without ample knowledge to make it out there. Even those who were encouraged to stay ended up performing very poorly because they seemed not to have an interest in schooling. There results were clear evidence that something needed to be done to increase their numbers. It was found that in the late eighties, close to sixty seven percent of the students who sat for the GCSE exam got marks that fell below the A to C grade. It was therefore necessary to introduce a system that would encourage students to tackle the whole journey and complete it. (Kingdon and Stobart, 1998) You can get expert help with your essays right now. Find out more The government introduced the Education Reform Act of 1988; it was designed to encourage schools to admit more students. The government started funding schools directly rather than through the use of local government. Schools that admitted more students were liable to greater funds than those with lesser numbers. Parents were also given the choice of deciding which schools they would like to take their children. This was one of the most evolutionary policies because it allowed them to make the choice for themselves. (Gibbons, 2005) Alongside choice, parents were also given the choice of deciding who would be representing them in school boards. Schools were expected to be more accountable to parents by giving them more information about themselves. In light of those changes, the government introduced league tables. These were publications of students’ results in the newspapers highlighting the performance of those at the age of sixteen. It provided information about the best schools so that other non performing schools would be encouraged to improve. (Le Grand, 1993) Overly, the reform was aimed at making schools market themselves. They were not allowed to fall out or fail in the creation of a good market standing. As the years went by schools have a sort of quasi market in which their fate lies in their own hands (Gibbons, 2005) The main impact of this reform is that overall retention rates in the education system have increased. There have been more students completing their education and many of them are pursuing higher education. However, when one examines this issue critically, they realise the highest number of students getting retained in good schools come from privileged backgrounds. When schools market themselves, parents with higher income sources are able to afford the best schools because it is very likely that those very schools have the resources and personnel to achieve good performance. Consequently, this policy has brought about some elements of inequality in the UK education system. Most people from low income backgrounds lack the ability to afford good schools as seen from statistics. This has brought about social-economic disadvantages among members of the education community.(Le Grand, 1993) Despite these social problems, one must not ignore the facts on the ground; the number of students passing the final exams has increased. Whether some of them are coming from certain backgrounds does not undermine the increase in numbers. Centralisation During the early nineties, the UK realised that there was inadequate literacy levels among members of the adult population. Research conducted in this area revealed that this field needed some improvements. Surveys were done among young adults and older ones. The older ones were found to have average rates of literacy. However, the younger adults were found to fall below average levels compared to other countries who participated in the surveys. (Machin and McNally, 2004) These were the reasons why the UK government decided to change its curriculum. It created a national curriculum that was common to all schools. This was necessary in order to ascertain the same standards were maintained throughout all schools within the country. It was also done to ensure that those standards were high such that students could attain the high levels of literacy. The UK decided not to leave the duties and responsibilities of making a curriculum to specific schools but has introduced a national curriculum. These changes applied to students between the ages of seven to sixteen years.(Vignoles and Machin, 2004) Centralisation in the UK education sector has also taken the form of National Numeracy and Literacy classes. These are classes that are supposed to be taught on a daily basis to students in primary schools. They are meant to reinforce good literacy skills. Rigorous methods of assessment for these methods are also available from the government. Its main aim was to ensure that children leaving primary school had basic literacy skills. Tests were also conducted to ensure that students can adhere to requirements. Students are expected to sit for tests at the ages of 16, 14, 11, and 7 corresponding to key stages 4, 3, 2 and one. (Besley and Ghatak, 2003) The impact of this reform was that parents became more aware about what their children are learning. On top of this, nationalisation of the curriculum has the ability to standardise teaching processes. In the past, the education sector in the UK has had serious problems in recruiting competent and intelligent teachers. This was as a result of the negative mentality associated with the teaching profession (most bright students think it is below them); most teachers may not be very efficient in the teaching process. They therefore require some sort of guide to help them in determining what the right and wrong materials for teaching are. This was the reason why some of them were not choosing the right areas to address. A national curriculum is therefore an aid to teachers who may otherwise not know exactly what to teach.(Machin and McNally, 2004) Find out how our expert essay writers can help you with your work A survey done during 2004 in four hundred schools implementing the national curriculum shed some light on the impact of this policy. It has shown that attainment of literacy has greatly improved and children have better knowledge. However, these schools that showed the highest levels were the ones that observed strict adherence to stipulated requirements. (Hoxby, 2003) Admission into fields of higher education During the nineties, the UK government realised that there are few people who pursue higher education. This could be attributed to the fact that most of them had not done so well in their GCSE exam and therefore felt no need to continue. Some of the people who made the choice not to pursue higher education ended up joining vocational schools. This is not such a bad thing when results emerging from it are capable of earning those students respectable jobs in the market. But this was not the case, most students attending vocational training were not able to get good jobs and this left a lot to be desired in the field of education. (Bradley, 2001) One policy that was passed in response to this need was the improvement of Vocational training. Since UK realised that there were substantial members from student bodies who preferred this system, then they decided to improve it. The government has focused on making vocational training more professional and lucrative in the job market. This has been achieved through introduction of the National Vocational Qualification which was designed to make this field more streamlined. The policy introduced the issue of apprenticeship where students could attend regular classes but at the same time practice their skills at a work place for a period of three years. This would go a long way in ensuring that students who complete vocational training are highly qualified and have adequate capability to meet the demand of the highly competitive labour market.(Dearden, 2002) Another aspect of policy within the UK that deals with encouragement of students to join higher education is the issue of Education Maintenance Allowance. This policy was introduced in order to encourage students coming from low income households to continue with higher education. This was a fee given to students between the ages of sixteen and nineteen who came from families that received low incomes. Homes that qualified had to be below a certain criteria designed by the government. The government realized that even if the quality of vocational schools had been improved, this was not enough to increase the numbers of students coming from poor homes. The allowance is continuously increased when students improve their performance thus encouraging them to keep up with attendance and to perform well.(Hoxby, 2003) You can get expert help with your essays right now. Find out more These reforms have had several effects on the education system in the UK. First of all, maintenance allowance has been very successful. A survey done on the year 2004 showed that there are 4.5 percent more students who continue onto higher education as a result of the introduction of an allowance. Besides this, it was found that retention rates increased to seven percent among males in their second nature. The research shows that most of these students were hindered from participating in higher education because students had insecurities about sources of funding. (Hansen and Vignoles, 2005) However, the vocational policies passed have not been very effective in bridging the gap between the academically qualified students and students who have passed through vocational training. The problem with this policy is that is has undergone too many reforms, consequently, employers are not aware of the exact curriculum that students follow within those vocational schools. Employers shun students who come from vocational schools because they believe that these students are the weak ones who could not qualify for other formal education systems. Some employers even prefer workers without any qualifications at all. The government should therefore focus on other more productive policies.(Chubb and Moe, 1990) Conclusion Education policy in the UK is constantly evolving. The most promising of these policies is that of inclusion of special needs children into mainstream schools. Vocational training policies have not been effective in encouraging students to pursue higher education. However, introduction of a centralised curriculum has improved performance. Similarly, introduction of quasi markets in education have also been highly successful.(Dixit, 2002) Reference: Besley, T. and M.

Chevrolet Advertising :: Marketing Advertisement

Missing Figures/Works Cited Genuine Chevrolet Advertisers create ads in magazines to catch the eyes of readers and encourage them to want to buy the product. Each advertisement includes claims, warrants, and supports, which make the advertisements attractive. For example, in the attached advertisement for Chevrolet Cavalier, each of these ideas used, makes the reader want to go out and buy this car. In the advertisement, there are many catchy phrases and pictures which make the car look very desirable. Furthermore, the general nature of a magazine such as "People," where the ad is found, it attracts people of all types. As displayed in the Chevrolet advertisements, claims, warrants, and supports are used to attract people of all types. Claims in the advertisements are used to try and get people of all types to notice, admire, and eventually go out and buy this car. There are three different types of claims: policy, fact, and value. The claims of policy in this advertisement are similar to most claims of policy in ads, which are, "buy this product." The claims of policy are created by the pretty picture on the opposite side of the page, and the writing on the ad. In the picture, the pretty mountains and bright sun look very inviting to someone who needs sometime to relax. By the desire to have free time, the busy worker will think that the car will get them some free time. Then, they will want to buy the car. The writing includes lines such as, "Finally. After working for what seems like forever, you have some time to yourself." Although this quote really does not have much to do with the car, it attracts the reader who may want some free time. The claims of fact include the statements about how many miles the car can go before needing a tune up and how it fits a low budget. These kinds of claims can attract people of all kinds, mainly people looking to spend little on a car for themselves or for their children. The claims of value state that this car can take you wherever you want, and that "even though going out during your free time may cost a lot, getting there won't." From these examples of claims of policy, fact, and value, the car looks very attractive to a reader.

Goals of the monetary policy :: essays papers

Goals of the monetary policy Goals of monetary policy are to "promote maximum employment, inflation (stabilizing prices), and economic growth." If economists believe it's possible to achieve all the goals at once, the goals are inconsistent. There are limitations to monetary policy. The term "maximum employment" means that we should try to hold the unemployment rate as low as possible without pushing it below what economists call the natural rate or the full- employment rate. Pushing unemployment below that level would cause inflation to rise and thereby ruin the other objective--stable prices, economic growth, which is our objectives in the long run. Overall financial stability will lead to a better balance between consumption and saving that will make resources available for investment purposes, reduce changes in the economy created by the inflation in the past, and by the reactions of savers, as well as fostering high and sustainable economic growth; and contribute towards an investor friendly environment that will attract foreign investors to the country. Evidence has suggested that economies perform better, in terms of growth, employment and living standards, in low inflation environments than they do when inflation is persistently high. This evidence is a comparison across countries over long periods. The association between economic performance, measured by growth of output or growth of productivity, and inflation.

Cult Conversion: Freewill Or Brainwashing? :: essays research papers fc

The controversy surrounding new religious movements seems to be foremost concerned with whether or not the members of these religions come of their own freewill or if they convert as a necessary and inevitable response to advanced coercion, or â€Å"brainwashing† techniques employed by the cult leaders. The concept of brainwashing came into popular existence in the 1950’s as the result of attempts to try and explain the behaviour of some American GI’s who defected to the Communists during the Korean War (19 Oct 1999). Many people, including some professionals, found brainwashing to be an acceptable explanation for the otherwise unexplainable behaviour. However, the brainwashing theory did nothing to explain why hundreds of other captured GI’s chose to remain true to their country even at the risk of being tortured. It could not accurately account for the behaviour of a select few GI’s when it did not offer any explanation for the behaviour of the majority. Since the 1950’s, the concept of brainwashing has faded in and out of public consciousness with a tendency to flare up again in the face of public controversy. In the 1960’s and 1970’s the brainwashing debate again took center stage, this time in an attempt to explain the behaviour of so-called radicals who left behind a â€Å"normal† life and opted instead for a â€Å"cult† existence. Although scholars of new religious movements would agree that religious groups often have substantial influence over their followers, they would also argue that the â€Å"influence exerted in "cults" is not very different from influence that is present in practically every arena of life,† (19 Oct 1999). Mainstream religions also exercise influence over their members concerning matters such as lifestyle choices, familial relations and monetary donations. Furthermore, most social scientists concede that some degree of influence is inevitable in each culture and facet of life even outside the arena of religious choice. Despite the fact that there do not appear to be any studies that conclusively provide evidence of brainwashing as a legitimate explanation for joining an NRM, and in spite of the many studies that have refuted that brainwashing defense successfully, the brainwashing theory continues to be debated regularly. The concept of brainwashing is still often relied on to account for behaviour that is otherwise culturally unjustifiable. If brainwashing is not an appropriate explanation for the conversion of people to NRM’s than what is? A common theme on the anti-cult side of the conversion debate is the argument that members are, to varying degrees, predisposed to becoming cult members.

Cornwall

Cornwall is the place I love to be, it is filled with lovely places to see, beautiful beaches of golden sand, which you can just spend hours walking on or looking out across the ocean, there are quaint little villages, sea ports and harbours. I love going to St. Ives this is my favourite place, it is just a small harbour town but packed with interesting things to do.You can have boat rides round the coastline, fishing, seeing the sea life, there is a museum where you can see how people made a living and the tragedies they went through and there is also a recording of the locals talking about how they have seen the changes in their lifetime. There is also a life boat station there which has it's own stories to tell. Driving through St. Ives can be a bit scary as the roads are very narrow, there is just enough room for one car to pass through, so most of the road near the harbour are one way.You also have art galleries, food shops, pubs and restaurants, hotels and holiday homes. As you walk through the back streets you find that the locals occupy the houses and it is less noisy. I like to sit on the harbour front and watch the boats coming and going and local fishermen selling their catch, also watching the sea rippling in and out, at night it is lit up lovely and is packed full of locals and holiday makers all enjoying themselves. There are other places to visit like the Eden Project at St.Austell which has the worlds largest greenhouse, two massive conservatories one of which is a rain forest and the is for fruits and flowers from different countries. The grounds are landscaped and produce tea, lavender, sun flowers and I think a desert conservatory is going to be built there too. The national trust owns and protects over 220 miles of the Cornish coastline, there are loads of coastal walks from just a gentle pace to hard hiking, oh that's not for me though.I have visited the lost gardens of Heligan and was totally blown away by what I saw, it was truly wonderfu l and to think it could have been lost for every would have been very sad, but to explore the whole of it would take at least two or three days. I was only there for one day and really I didn't see it all I was taken back with the plants and ponds and to think this was all made possible by the Tremayne family and now their descendants have found it and stated about restoring it with help from other sources, this is well worth a visit.Other places to visit is Porthleven another harbour town, the Minack theatre which was the inspiration of just one lady Rowena Gade, Charlestown Heritage, Shipwrecks and China Clay, well worth a look you also have Bodmin Moor which is one of the last unspoilt areas in the south west and I have also seen some beautiful church's driving through some of the Cornish towns.Across the coast you will find surfers trying to catch the perfect wave, they make it look so easy. You can also so some crabbing in the crab pools in Perrinporth. Newquay is a buslin town with loads of shops, arcades, pubs, beaches and night life. And now what I don't like about Cornwall, well that's easy to answer,it's leaving

Food Processing Essay

Introduc? on Food science is a ? eld embodying the applica? on of modern science and engineering to the produc? on, processing, diversi? ca? on, preserva? on and u? liza? on of food. Food is very essen? al to man’s survival and great a? en? on should be paid to food produc? on, distribu? on, wholesomeness and preserva? on. To ensure that food is clean and safe for human consump? on and having keeping quality, food scien? sts are responsible in seeing that the crop harvested, the ? sh caught, that animal slaughtered, the egg laid and the milk produced reach the consumer in the most acceptable, nutri? ous safe and wholesome condi?on by carefully studying the chemical complexi? es of food, their vulnerability to spoilage, their disease vectors and varying sources of produc? on. Food scien? sts try to eliminate seasonal gluts and shortage by providing a technologically sound base for the levelling out of food surpluses and shortages with and among countries and regions. They also see to the remedy for the malady of post-harvest losses in food grains in the highly industrialised socie? es has been the development, along with increase in yield poten? al of adequate storage and low- cost processing technologies to preserve and store the harvest. The development and produc? on and new nutri? ous foods to improve the diet of people su%ering from malnutri? on, the provision of adequate group – speci? c diets for the young and adults performing under condi? ons of stress, pregnant and lacta? ng mothers, kwashiorkor and diabe? cs pa? ents. Scope of food science The scope of food science is in threefold: 1. To make it possible to assemble the great quan es of food required by a crowded popula? on. 2. To make the food agreeable to the consumers that is to say, to provide them so far as is possible with the kind and quality of food they demand at all ? mes of the year doing this partly by carefully controlling the quan? ty and uni-forrming of the commodi? es produced and partly by constant e%ort to produce something new ( a new breakfast food, a new kind of co%ee essence or indeed a new kind food altogether and by these mean keeping up with popula? on demands). 3. To maintain and improve the nutri? onal value of the total food supply and hence the health of the community ea? ng it. Basic principles of food science Food processing and preserva? on either local or interna? onal mist follow basic principles 1. Working surface and environment must be kept clean and spillage must be wiped o%. 2. Food processor must observe personal hygiene, which involves cleanliness and care of the body to prevent the spread of infec? ons. 3. Cleaning utensils should be used during the processing food in order to prevent food contamina? on. 4. The process ad preserva? on area must be clean always so that the task of the food prepara? on and preserva? on may be performed without hazards to the body. Brief history and growth of food science The history of food science can be traced back to ancient ? mes from ? me immemorial individuals and community have organised themselves in various way to provide for the preven? on of food microorganisms which leads to deteriora? on of food, processing and preserva? on which leads to treatment and promo? on of health eaten wholesome food. In 1840 industrial revolu? on was started in England, which brought about of food science during this period. There was extensive industrial use of newly developed machine e. g. the steam engine and mass produc? on techniques. Also during the ? rst and second world wars, there was increase in the bulk manufacture of food as a result of commercial feeding in most part of the world. Therefore the prepara? on centre became over u? lized including sta%, which eventually results to the gross contamina? on of food. This helps in crea? ng the awareness from ? me to ? me to safeguard the produc? on of food, and totally free from micro organism from food which are meant for consump? on. Rela? onship between food science nutri? on and diete? cs Food science deals with the basic chemical, bio chemical, physical and biophysical proper? es of foods and their cons? tuents, thus very closely related to nutri? on which is the study of the nutrients in rela? on to their func? ons in the body. It also involves the study of the chemical and physical proper? es of the nutrients, their food source, de? ciency symptoms and their appropriate propor? on in a balanced diet. These two (food science and nutri? on) are related to diete? cs in the sense that the diete? c is the prac? cal applica? on of the principle of nutri? on, which includes the planning of meals for the healthy and the sick. Assignment What is rela? onship between food science catering and hotel management. Food processing. There are methods involved in prepara? on of food. These methods include material handling (washing, cleaning e. t. c ) during, mixing, crushing, hea?ng, cooling or freezing and packing). Reasons for food processing 1. To prevent food spoilage. 2. To prolong shelf life. 3. To avoid was? ng of food especially when they are in season. 4. To allow for the use of food during the o% – season. 5. To introduce variety into the family menu. 6. To eliminate the purchase of the food when they are most expensive. 7. To be able to take care of emergency situa? ons. Food preserva? on Food preserva? on is the act of keeping food for a longer period of ? me before it is consumed. It may involve the addi? on of other substances or changing the form of the foodstu% to another food through processing or keeping the food especially designed containers or equipment. Principle underlying food preserva? on The act of food preserva? on is based on the following: a. Destruc? on of microorganisms. b. Preven? on of microorganism entering into the food. c. Arrest of the ac? on of food enzymes. 10 methods of food prepara? on Drying: this is the process which the water content of the food is reduced. Both food enzymes and food microorganisms require water for ac? on and growth. The removal of water from the food creates an unfavourable environment for their ac? on and growth, hence they are unable to cause food spoilage. Drying can be achieved by sun drying or by ar cial dryer or roas? ng on a ? re. Examples of food preserved by drying is legumes, cereals, meat, ? sh etc. the preserva? on of food by drying can either be by dehydra? on or concentra? on. A i. Dehydra? on: is the process by which all the water content of the food is removed and the resul? ng product is very dry and break with a snappy sound, food items usually dehydrated are ? sh, meat, yam cassava, cereals and legumes. ii. Concentra? on: is the removal of a considerate amount of water from food stu%s by the applica? on of heat, cooking e. g. tomato puree, pepper puree etc. There are di%erent types of drying which are solar drying, oven drying, freezing, roller drying, vacuum drying, tunnel drying and spray drying B. Applica? on of low temperature: this is the process of keeping food at a low temperature e. g. chilling and freezing. In chilling, the food is kept in the refrigerator while in freezing, the food is kept in the freezer. Freezing is keeping the food at a temperature below 0oC or 32oF, which solidi? es the food. Freezing keeps food longer and completely arrest the growth o% microorganisms and the ac? on of food enzymes. Chilling on the other hand does not completely arrest enzymes ac?on and bacteria growth. Food items preserved with this method are ? sh, meat, milk, fruits and vegetables C. Applica? on of high temperature: this involves the destruc? on of food enzymes and microorganisms by hea? ng. Both enzymes and microorganisms are proteinous in nature and when they are heated; their protein becomes denatured and hence rendered inac? ve. This method can either be by pasteuriza? on, steriliza? on or blanching. I. Pasteuriza? on: is the applica? on of heat to foodstu% under 10oC. the objec? ves of the heat is not to destroy all the microorganisms present in the food but only the pathogenic ones. Pasteuriza?on has a minimum e%ect on the nutri? onal proper? es of the food. It is usually carried out in three forms. Low temperature long ? me (LTLT), High Temperature Short Time (HTST), Ultra High Temperature (UHT) in this process the hea? ng temperature is very high but the dura? on is very short e. g. milk can be heated at 125. 25oC for 14 seconds. II. Steriliza? on: is the heat treatment of food at a very high temperature. The objec? ve of steriliza? on is the destruc? on of all the microorganisms present in food. Thus it is a more severe heat treatment of food than pasteuriza? on e. g. tomato puree, canned meat and ? sh etc. III. Blanching.
