Principles of learning - Essay Example Constructivist theorist belongs to the third category, which believes that the learning abilities of students are influenced by prior knowledge and information on the same topic (Brauer & Tittle, 2012). In this paper, learning theories will be discussed in relation to Petra, a polish child living and studying in the United Kingdom with his parents. The paper will discuss the relevance of the learning theories according to her concerns and the strategies that the family and the school can adopt to support her learning process. A number of learning theories have been developed that enhance the process of educating children from different family background like Petra in this situation. According to the sensory stimulation theory, the process of learning can only be effectively achieved if all the senses of the student are stimulated. Laird who noted that the information held by adults has been learnt through seeing first developed this theory. As seeing accounts for 75% of all the information held by an individual, hearing accounts for 13% while smelling accounts for the remaining ratio (Sammut, 2014). This highlights the essence of stimulating the senses during the process of learning before actual information about facts that have been recognized by the sensory nerves can be discussed. As a student undergoing a challenging moment because he is in a non-familiar country and setting, the sensory organs of Petra are less involved in the learning process and this affects her information absorption and retention. As the learning process continues, Petra is absorbed in thoughts about her family and her mother country and this affects her cognitive ability to grasp the information being discussed by the teachers in class (Brauer & Tittle, 2012). By using the sensory simulation theory, the teachers of Petra will engage all his senses in the discussion and enable him to forget the memories of his country and family and focus on

Contributions of Biotechnology to Agriculture

Contributions of Biotechnology to Agriculture Introduction The Food and Agriculture Organization some 20 years ago released a paper stating that the amount of food produced worldwide will not be able to provide the constant nutritional needs for the world population by this year (2010) as a staggering 25% increase in world population was projected, though this estimation has not materialised, it has generated a lot of concerns as there has been a 4-fold population increase in the last century (1918 2009) which has led to the applications of biotechnology to agriculture or in other words the Agrobiotechnology to enhance maximum food production in an economic way. The need for the application of biotechnology to crops was also necessitated as a result of the massive crop loss due to insect pests as at that time was treated with pesticides which are expensive and thus there was a need to sustain the productivity yields of crops which was not given much of a chance as world population was on the rise. Biotechnology was able to provide prospects of producing novel, developed, safer and inexpensive crops in agricultural practices. (Brown, 1992) Agriculture is defined simply as the activities involved in the production of food crops and rearing of livestock animals, while biotechnology was defined jointly by FAO and WHO (1996) as the integration of natural sciences and engineering sciences in order to achieve the application of organisms, cells, parts thereof and molecular analogues for products and services. Therefore Agrobiotechnology techniques according to Huttner et al, (1995) are implemented to reduce cost of production of crops and increasing food productivity by; increasing food quality and food processing traits, adequate disease or pest resistance, improving environmental stress tolerance, and the control of weeds which has led to the development of (genetically modified) GM crops in some parts of the world. Plant breeding techniques with the use of molecular markers such as RFLP, RAPD, AFLP, SSRP, CAPS and SSCP were improved for plants genome mapping as well as to determine plants phenotypes and select desirable traits for the proper modification of crops depending on the gene of interest that is to be incorporated into several populations of plants or crops generated by crosses. (Mohan et al, 1996) Several biotechnology approaches have also been applied in livestock farming basically because there is a general belief that the biotechnological steps to humans are just one step ahead of those applied to animals which involves the modification of animals to observe desirable traits. (Becker and Cowan, 2009) According to Fernandez-Cornejo (2008), the fundamental contributions of the application of biotechnology to agriculture depends on the acknowledgement of its prospective possible benefits and risks, however, this essay will focus on the potential contributions of biotechnology to agriculture (plants and animals) taking into account the advantages as well as the disadvantages of the technology Plant (Crop) Biotechnology Plant biotechnology developments was based on the cell theory as described by Vasil (2007) and has witnessed remarkable expansion in the last 10 years which has focused majorly on making crop production efficient and producing crops with desired traits. Plants and crops need to overcome some Biotic and Abiotic stresses to increase their productivity which led to the introduction of genetically modified (GM) crops about 20 years ago which have been commercialized over the past 10 years either with single traitor multiple traits GM crops as the name implies that genes of a crop are taken and transferred to another crop or already present genes are manipulated with the main purpose of changing the features of the crop in question which may be either the way the crop develops or matures. Addressed in the next paragraph are traits that have been transferred to biotechnology or GM crops to increase their yield. Insect/pest resistance Ferry et al (2005) estimated that 10 20% of major crops are lost to insects or pests and crops are genetically modified to be poisonous and harmful to pests that attack the crops, an example is the application of Bt (Bacillus thuringiensis) genes to grow cotton (in China and South Africa) and corn thereby reducing pesticide use, increasing profits, yields and health benefits to farmers who apply pesticides without protective clothes. (Nuffield Council on Bioethics, 2004) Disease resistance Described in details by Raybould and Gray (1993), fungal, bacterial and viral infestations to crops and plants have been suppressed by genetically modifying plants to be disease resistant for example the ongoing research to reduce the viral and fungal infections to sweet potatoes and bananas respectively. Abiotic stress resistance Motavalli et al (2004) discussed the ongoing extensive research to modify crops to be able to survive in unfavourable environmental conditions such as drought, heat, cold, frost, extreme soil conditions and significantly increase food security for example the use of trehalose genes to grow rice in India to protect it from dehydration. Herbicide tolerance This trait enables a wide range of weeds to be controlled by modifying crops to be resistant to the effects of weed thereby lowering costs of herbicides, reducing tillage and effective weed control measures as discussed in Sharma et al (2002) in the growth of soybeans in Argentina. Improved nutritional value Plant biotechnologies has enabled crops to be modified to contain supplemental nutrients inadequate in diets for example the enhancement of ÃŽ ²-carotene in rice to increase vitamin A to prevent blindness which is as a result of vitamin A deficiency. Biopharmaceuticals Biotechnology applications in plants has been used to produce vaccines and medicines according to Sharma et al (2002) which has enabled production and easy distribution of cheap vaccines as in the modification of potatoes to produce bacterial vaccines for E.coli. GM crops have been widely accepted worldwide (25 countries currently) both in industrial and developing countries as shown in figure 1 mainly because of their advantages which are either economical or environmental. Apart from the fact that plant or crop biotechnology has improved the productivity and yield of crops, other economic benefits in relation to the features of GM crops are further discussed; As described by Nuffield Council on Bioethics (2004), the growth of a large variety of crops by farmers have been enhanced as there a good resistance to biotic (insects, pests or diseases) and abiotic (drought, frost, heat) conditions. With the resistance of GM crops to insects and pests, the use of pesticides is greatly reduced which in turn reduces the costs of growing these crops. Farmers are able to generate more income owing to the reduction of the cost of farming and generation of higher yields which consequently reduce the prices of crops thus alleviating poverty and starvation levels in the economy. GM crops have an improved nutrition levels thus sicknesses and illnesses are consequently averted with a better diet even in underdeveloped countries. Since GM crops can remain fresher over a long period of time for example in tomatoes, the shelf life can be increased in the market. The ability of GMO crops to withstand abiotic conditions such as drought has increased food security while the cheaper production of biopharmaceuticals such as vaccines and other medicines in GM plants has led to a great ease of distribution and manufacture of vaccines thus improving healthcare systems. Environmental benefits of GM crops as discussed by Gatehouse et al (1992); Wieczorek (2003) and Gatehouse (2005), includes the less use or no use of pesticides and insecticides which may be contaminants in the environment (land or water) and could accumulate as residues on foods thus more environmental friendly pesticides can be used while in most cases there is no need to use pesticides. Natural resources sustainability is also improved as there is less use of energy or chemicals (pesticides) while natural habitats are conserved for more efficient applications. GM crops have reduced the pressure on vegetation and biodiversity is maintained while there is a less risk of desertification and soil erosion since GM crops can be grown anywhere irrespective of abiotic conditions. According to the advantages of biotechnology described in figure 2 above, these benefits can only be achieved if the risks and concerns which constitute the disadvantages are investigated, realised and averted. (Mannion, 1995). The potential risks of biotechnology applications to crops and plants can either be health related, environmental or social as further discussed. Wieczorek, (2003) discusses the potential risk of introducing toxins and allergens into GM crops while genetic modification technology is underway is of great concern as there is a potential risk of allergens and toxins being transferred into improved crops while also emphasizing the concerns raised about the use of molecular markers during gene transfer as there is a potential risk of diseases being resistant to clinical antibiotic treatments as a result of transfer of resistance encoding genes which may contain novel bacterial strains. Of great concern as discussed by Hobbs and Plunkett, 1999 is the fact that the long term health effects of the consumption of GM crops over a long time is unknown. Of environmental concerns is the potential risk of GM crops hybridizing with related weeds which may result in superweeds that are more complicated to manage while genetic modification of plants could pose a risk of unintentional gene transfer to non GM crops from GM crops thus the former become wild plants creating ecological instabilities as discussed by Soregaroli and Wesseler, (2003). Wieczorek, (2003) suggests that the release of GM crops into the environment may pose unpredicted and adverse effects as it was emphasized by the fatal actions of Bt corn on the larvae of Monarch butterfly, though the possibility of this happening is very doubtful. Due to the fact that insect pests may get resistant to crop-fortification traits of GM crops, a swift resistance can build up among pest populations as it was feared with Bt crops while biological diversity in nature stand a great risk of being adversely affected as there may be an increase on the reliance of GM crops which could intensif y failure of non-GM crops and put at risk food security. A social concern as discussed by Persley and Siedow, (199) raises the arguments of GM crops being labelled as practiced in the U.S.A where Gm crops carry a label showing a difference in while another concern is the inadequate access to seeds of GM crops or food plants that have been patented as these seeds cannot be saved for replanting. GM crops/food plants have been referred to as unnatural by critics as they are modified by humans and not found in nature as other crops created by God thus causing uproar of religious and ethical concerns as discussed in Knight (2008) while it is feared that these GM plants could someday turn into weeds, adversely affect the natural ecosystem due to direct and indirect impacts on non-targeted plants/crops as described by Azadi and Ho, (2009). Animal Biotechnology Animal biotechnology was described by Cowan and Becker, (2006) as series of techniques by which living beings are genetically modified to benefit humans and animals by exploiting and introducing desirable trait which is as a result of the genetic code being discovered in the early 1950s with technologies including embryo transfer, transgenics, in-vitro fertilization, sexing embryo, cloning and gene knockout but with transgenics being the most commercialized while cloning being the technique surrounded with much controversy. Animal biotechnologies have not received much attention as attributed to plant/crop biotechnology as there is so much controversy surrounding its applications as there is a general concern that these applications could one day be applied to humans since its just a step ahead of the applications to livestock to observe desired traits. Embryo transfer, In-vitro fertilization, sexing embryo and even cloning can be classified as reproducing technologies that have several advantages as described by Gordon, 2004 which includes; the improvement of the reproducing capacities of livestock, the reduction of the level of infertility in animals, enablement of old livestock to donate ovules if they cant maintain pregnancies, the observation of specific sex (male or female) as desired traits while the embryos in all these techniques can also be stored in an embryo bank and can be easily retrieved when required. Gene knockout/targeting techniques has a major advantage of increasing the knowledge of stem cells and similar genes that may be present in humans and livestock and can be use to study diseases and ailments as discussed by Serhan and Ward, (1999). Cloning of animals is also advantageous; as it provides farmers with a range of better performing animals in a generation, is used to improve the population of livestock or endangered animals while inexpensive and many biologically engineered drugs can be modified by using genes that can encode proteins from human as discussed by Van Niekerk, (2005). Application of transgenics which is performed either by microinjection or homologous recombination however is the most advantageous and commercialized animal biotechnology with several examples as shown in table 1, below. As numerous as the advantages and contributions of animal biotechnology are, there are still health, environmental and social concerns that want to constitute as disadvantages to the biotechnology applications for instance the safety of food from GM animals could pose a threat to human health as unpredicted and unintended changes may arise in their composition while environmental issues are based on the break out of gene flow into natural populations as feared especially in superfish as escape into habitats will disrupt natural ecosystems and may cause the introduction of undiscovered genes into the environment. Cowan and Becker (2006). Social acceptance concerns has been a major disadvantage of animal biotechnologies as discussed by Becker and Cowan (2009) which arise from labelling, welfare of animals, genetic biodiversity and trade issues have limited the commercialization of animal biotechnologies.

Comparing the ‘Club 18-30’, ‘Superfamily’ and ‘Forever Young’ brochures

Media is the means of communicating news and information to the public via printed and visual media. In contemporary society printed media has become an essential way to advertise a product to its target audience, as it is a cheap and accessible form of communication. Furthermore, examples of printed media can be seen in many different ways as they are varied forms such as leaflets, newspapers and brochures. For this particular piece of coursework I will be comparing the ‘Club 18-30', ‘Superfamily' and ‘Forever Young' brochures and seeing how they attract their target audience by using various linguistic and presentation devices. The Club 18-30 brochure appears to be aimed towards a younger and more outgoing audience who are partygoers. This can be seen through its choice of layout and organization. Although its layout might appear rushed and erratic to the older and untargeted section of society, it actually provides the younger generation with all the qualities needed in a good club brochure. The layout and organization can also be seen to be enticing as it engages the younger audience because of its simplistic form. However through the choice of layout and organization of the ‘Superfamily' brochure the audience immediately realises that the brochure's target audience is families with young children as shown by the childish qualities of the presentation: bubbles, distinctive colours etc. The layout and organisation of the Superfamily brochure is different to the others as it is clearly trying to lure children and their parents to read the brochure. Furthermore, the ‘Forever Young' brochure identifies its target audience, which appears to be mature sophisticated adults. This is shown through the layout and organization of the brochure, as it is well structured and organised. The brochure appeals to this specific type of audience since mature reserved adults are not interested in a humorous brochure as they care not for the brochure's appearance, this is shown in the brochure's text layout and organisation as most young people in a contemporary society will find the brochure dull and tiresome. The use of presentational devices in the Club 18-30 brochure reinforces the sense of reliability and authenticity, as shown by the logo of the brochure, which informs the audience that the club is an established company. Furthermore the logo specifies its target audience and uses eye-catching colours, red and yellow, reflecting the sun to entice the reader to continue reading the brochure and display the enjoyment many experience at the resort in order for people travel to the resort so they can participate in the excitement. Equally the picture succeeds in attracting its the target audience in a similar way as it enhances the sense of reliability and enjoyment, which is shown by the way the people in the picture are presented as enjoying themselves. Sub headings are also used to empathise with the audience and deal with essential questions but can be slightly abrupt by reflecting the demanding attitude of many young people. Furthermore the Superfamily brochure appeals to its target audience with its use of presentational devices such as; the irregular shape of its picture, which develops the child theme of the brochure as it is something interesting to a child would enjoy. The central, socialising picture, also illustrates the lively yet relaxed social scene for all the family and focuses on the more relevant aspects of the holiday for a family holiday, such as the accommodation, which clearly guides the reader suggesting it is a comfortable and secure environment for young children. On top of this, bullet points and sub-headings are effectively combined to summarise key points of the holiday and focuses the reader on essential information as parents need this useful information to organise their holiday so that they may feel that their children are being catered for. Additionally the use of presentational devices in the Forever young brochure enhances the quality and sophistication of the brochure, as devices such as bullet points and sub-headings are used to organise and structure the most useful information and present it in an informative way. The two pictures in the brochure also illustrate the accommodation but balance it with interesting educational places to visit on the holiday. This is done in a controlled manner, as the brochure seems to be aimed more towards mature sophisticated adults who would expect formality and professionalism. The ‘Club 18-30' brochure employs the use of informal language to engage its target audience as this type of language appeals to the youthful generation in the contemporary society. The line ‘you will need a fair bit of wedge because there's so much to do' demonstrates the writer desire to relate with younger people on an informal relaxed level, which helps the reader engage his audience because of its simplicity. Abbreviations like ‘Fab' and ‘Med' are used in the brochure to further empathise with the youthful audience and to manipulate them not to lose interest, as the brochure uses informal language they understand but mature adult would be less comfortable with, which confirms how ‘friendly' the writer to be towards young people, as obviously this is a device used to persuade and encourage young people to spend their hard earned money at the club. Further use of informal language can be seen in the line ‘enough to keep even the most hardened party animals happy' which challenges the reader and cleverly influences them to go to the club. Factual language can also be seen in the brochure but it is not excessive preferring to engage young people with informal and more evocative language compared to factual. However the Super family brochure takes a different approach compared to the Club 18-30, as the brochure is aimed towards families with young children. This is shown in the line ‘It has a beautiful one kilometre long beach of gentle-shelving white sand' where the brochure employs the use of emotive and factual language, which appeals to a wider audience rather than the expected target audience. The activities also listed in the first paragraph ‘Water sports are available, as well as tennis, go-karting and cycling' attractive active and out going people who are energetic. The brochure also empathises with audience in the line ‘No need to agonise over a menu' which inform the audience that their holiday will be taken care for them and illustrates a relaxed, calm, comfortable scene as many parents wish to do this on their holiday. The line ‘There are plenty of family activities' evokes a sense of security to the parents as they know what will be available for them to do on there holiday. The linguistic devices used to entice mature adults in the Forever young brochure vary from; factual language in the line ‘It is the largest of the Balearies' which is used to give a factual representation of the holiday, to emotive language in the line ‘an island of incredible beauty' to evoke a sense of anticipation for the holiday. The consolidating options in the line ‘it need never be the same resort twice' along with the emotive word ‘abundance' emphasises the numerous activities available in the resort and the variety available to the people on holiday. The simple sentence ‘Quite simple it has something for everyone' empathises with the audience and their needs, at the same time as informing the audience of the quality of the holiday. Through my analysis of the three brochures and their use of presentational and linguistic devices they can be seen to have engaged their targeted audiences effectively; as the brochures employ the use of formal, informal and emotive language to entice their targeted audience to the holidays the brochures are advertising. Furthermore, I can clearly announce that the brochures have achieved their fundamental purpose, as I have identified their targeted audience and empathised with them to get a clear understanding of the brochures are trying to convey.

Comparative Study of Common Vegetable Starches Essay

ABSTRACT The purpose of this experiment is to be able to help the society with its environmental issues by creating biodegradable plastic out of common vegetable starches. Here, the The procedures that the researcher use in this investigatory project were all experimental and were based on Scientific Method. The researcher used environment-friendly materials which can be made into biodegradable plastics that will not harm the environment and will not add to pollution problems. Among th The result was found that the product exhibited the desirable properties of a biodegradable plastic thus the product is completely biodegradable at disposal. The researcher conclude that among the different vegetable starches, _____________ starch is the most effective raw material for the development of biodegradable plastics due to its availability in large quantity, its relatively low cost and its biodegradability. INTRODUCTION A. Background of the Study The ever unending problem of waste disposal specifically the non-biodegradable one had contributed to the alarming worldwide problem of global warming. As an example, the experience storm surge of the island of Leyte due to increase of sea level, increase of water level among streets during heavy rain due to clogged drains, canals and sewerage. Using vegetable starches in developing biodegradable plastic is one big step to lessen, if not total eliminate, our global concerns. Generally, this study is conducted to replace the conventional non-biodegradable plastics to a more friendly biodegradable plastics using different vegetable starches. The cassava root is long and tapered, with a firm, homogeneous flesh encased in a detachable rind, about 1mm thick, rough and brown on the outside. Commercial varieties can be 5 to 10 cm in diameter at the top, and around 15 cm to 30 cm long. A woody cordon runs along the root’s axis. The flesh can be chalk-white or yellowish. Cassava roots are very rich in starch, and contain significant amounts of calcium (50 mg/100g), phosphorus (40 mg/100g) and vitamin C (25 mg/100g). However, they are poor in protein and other nutrients. In contrast, cassava leaves are a good source of protein, and are rich in the amino acid lysine, though deficient in methionine and possibly tryptophan. These components are components of biodegradable plastic. The squash The sweet potato B. Significance of the Study Once one of these vegetable starches known, this study will be very essential in the production of biodegradable plastics, which can lessen the tremendous piled up non-biodegradable garbages made by plastics thereby reducing harm  to our environment. C. Statement of the Problem The problem is to compare which among the different vegetables; squash, sweet potato and cassava, which are rich in starch will be an effective component for biodegradable plastic. D. Hypothesis Cassava starch is the most effective component for biodegradable plastic. E. Scope and limitations This study will be focused on the comparison of the three common vegetables, namely, the squash, principal variable of this project is the cassava starch. The locale of this project is it could help save the environment and reduce use of plastic that takes a lot of years to degrade. REVIEW OF RELATED LITERATURE The word plastic came from the Greek word plastikos, meaning capable of being molded. Plastics can be as hard as metal or as soft as silk. They can take any shape in almost any form due to the versatility of the carbon, the most common backbone of polymer chains. Plastics can be conveniently divided into two categories: semi-synthetic, in which the basic chain structure is derived from a natural product, such as cellulose; and synthetic, which is built up chemically from small units or monomers. Despite the various applications of plastics, drawbacks have been encountered in three major points. Firstly, there are certain chemicals used in the manufacture of .plastics that may cause allergic reactions. Three is a need man from these threat. Secondly, since cellulose films are biodegradable; they are readily attacked by bacteria. Films and packaging materials from synthetic polymers are normally attacked at a very low rate. New polymers such is nylon, polyvinyl chloride and Polystyrene have replaced cellulose, the pioneer plastic material. As a result, these plastic materials have become permanent wastes. There ‘are various methods in making biodegradable plastics. The simplest is the production of plastic from the extraction of casein from milk. Casein is obtained in two ways by souring, with the use of lactic acid, arid by boiling together with an additive, such as acetic acid. Starch is a natural organic polymer manufactured by green plants through photosynthesis s to serve as metabolic reserve It occurs in the form of grains in many ‘parts of the plant, principally in embryonic tissues such as seeds, fruits, roots and tubers. Polyvinyl alcohol is a colorless, odorless, tasteless, thermoplastic synthetic resin. It is usually used for grease-proofing paper, in adhesives, in gas- and oil-impervious films and Coatings. This substance, although soluble in water, is insoluble in Common organic solvents. Glycerol is the simplest trihydric alcohol. In commercial form, it is called glycerin. It is a colorless odorless and viscous liquid with a sweet taste. It is completely soluble in water and alcohol but is only slightly soluble in many common solvents, such as ether, ethyl acetate and dioxane. It is widely used in coatings and paints, pharmaceuticals and cosmetics. Plastic production is relatively new technology. Experiments are being conducted to relieve the negative effects ‘of overproducing plastics. By changing its raw materials and additives, commercial plastic may be improved so that it will become degradable while retaining its good quality. Cassava (Manihot esculenta), also called manioc, tapioca or yuca, is one of the most important food crops in the humid tropics, being particularly suited to conditions of low nutrient availability and able to survive drought (Burrell, 2003). The plant grows to a height of 1 to 3 m and several roots may be found on each plant. Although cassava leaves are sometimes consumed, the major harvested organ is the tuber, which is actually a swollen root. The plant is propagated mostly from stem cuttings. A major limitation of cassava production is the rapid post-harvest deterioration of its roots which usually prevents their storage in the fresh state for more than a few days (Okezie and Kosikowski, 1982). Cassava ranks very high among crops that convert the greatest amount of solar energy into soluble carbohydrates per unit of area. Among the starchy staples, cassava gives a carbohydrate production which is about 40% higher than rice and 25% more than maize, with the result that cassava is the cheapest source of calories for both human nutrition and animal feeding. A typical composition of the cassava root is  moisture (70%), starch (24%), fiber (2%), protein (1%) and other substances including minerals (3%) Compared to other crops, cassava excels under suboptimal conditions, offering the possibility of using marginal land to increase total agricultural production (Cock, 1982). METHODOLOGY Cassava Tubers were ground and squeezed to extract its starch. Starch obtained was weighed and divided into three equal parts; 50 grams in trial 1, trial 2 and trial 3. T1, T2 and T3 also consisted of 50 ml Polyester resin and increasing variations of Polymer MEKP Hardener; 50 grams for T1, 100 grams for T2 and 150 grams in T3. The components in every treatment or trial were mixed, stirred and then poured in 3 different shirts with Petroleum Jelly and then sun-dried. Afterwards, different methods were used to test the effectivity of the plastic. T1, T2 and T3 were sun-dried but they did not look like a plastic at all. The researchers observed the product while waiting for it to dry but there were no signs of turning into a plastic. The Cassava starch was too thick and the researchers realized that it would not turn into a plastic because of its heavy weight and it would take more time before it would dry because of its thickness. After letting T1, T2 and T3 dry under the sun, it became hard. Although the researchers had unexpected results and the Cassava starch did not turn into plastic, studies have already proven that Cassava starch could be used for making various types of packaging products. Cassava is a promising raw material for the development of biodegradable plastics.
