My Philosophy Of Education Is It Should Be About The...
My philosophy of Education is that it should be about the individual. In most of my experiences it has become just doing the same thing for each person, mostly book work, I think learning should be based on the best way a child can learn based on interests. If they become interested in learning they are more able to remember the lessons, whether that be done by using more hands on work or experiments. I believe the role of the teacher is to be an encourager or a mentor. The role of the teacher, I believe, is to be a facilitator for the students. I wish to teach high school, and as high schoolers they are at the age where soon they will become adults and think and act for themselves. Something students need to figure out is what is the best way to interact with the material and work with others. In the classroom, I want to encourage a community-like feel to it. I would organize my room where the students would easily be able to enter into discussions over the information. During one of my observations, the classroom was set up in two half circles and they were easily able to start discussing when told. This could change, as people are unpredictable, so I will need to be flexible and change in a way that will best help the student learn. In managing and disciplining in the classroom, the best way, I believe, is to make the students feel empowered. In order to do this a teacher has to give a little freedom in order to keep students from acting out.

Harmonized System Nomenclature and Classification â⬠Free Samples
Question: Discuss about the Harmonized System Nomenclature and Classification. Answer: Introduction Harmonized system is an international multipurpose product nomenclature that was developed by World Customs Organizations (WCO) to classify the traded goods (WCO, 2017). The parts and accessories are products of metallic in nature. For instance, when referring to automotives are the non-essential parts that add to the functionality of the automotive according to (World Customs Organization, 2017). Goods like the parts and accessories must always be classified under a specific tariff by choosing the item numbers that should be accompanied by language descriptions that are the most appropriate and more specific to that particular product. The item number that is selected gives the amount of the duty that is to be put on goods. Despite the fact that several merchandise descriptions are provided in the available tariff statutes disputes, do arise in the classification process management of goods (HS 2002 Classification by Section (Classifications, Commodity Codes, Commodity Description, HS 2002, HS code search), 2017). The conflicts do arise from three major issues that include the determination of the appropriate tariff term meaning, deciding on the classification of the article that is covered by several item numbers. These items are more than one, and the final problem that arises in the classification of goods is the classification of the new product that was initially not in existence now that tariff was adopted (What is a tariff code?: UPS, 2017). Incorrect classification usually results in the imposition of border penalties or the seizures and the non-compliance penalties. In the process of approaching the issues that make the classification of goods a head, tools have been provided to improve the data that exists in two major ways (Harmonized Commodity Description and Coding Systems (HS) (Classifications, Commodity Codes, Commodity Description, HS, HS code search, WCO), 2017). An algorithm which provides concordances between ten-digit Harmonized System codes that are used in the classification of goods in the international trade in the United States and SIC industry codes to classify the economic activities which are domestic. The other concordance is that between the HS codes and the SIC product or good used for the classification of United States manufacturing production management. Importance of the Harmonized system 200 countries and more as the basis for the customs tariffs and the purpose of collection of the international statistics of trade use the HS system, and more than 98% of the merchandise in the international trade uses the HS as the classification terms. The other benefit of the HS system is that it contributes positively to the harmonization of the customs and the trade procedure, as well as non-documentary trade interchange of data in connection with the procedures and therefore minimizing the costs that are related to the international trade (Harmonised System 2012, 2017). Harmonized systems are used by the private sector, international organizations and the government for the purposes that include trade policies, internal tax, origin rule, controlled goods monitoring, freight tariffs, price monitoring, transport statistics, economic research as well as analysis. Harmonized system classification is not always simple and easy, as it appears when people talk about it especially when it comes to the classification of the parts and accessories during the process (Memorandum D10-0-1 - Classification of Parts and Accessories in the Customs Tariff, 2017). The first challenge that is encountered in the classification is deciding on the classification of the article that is covered by several item numbers more than one. For instance, when it comes to the classification of the automotive parts, they are not classified under the 87.08 heading that provides for the parts and the accessories of most motor vehicles of 87.01 to 87.05 headings (Concepts and basics of Harmonised or HSN Codes for GST, 2017). The automotive parts are instead classified as furniture articles under the 94.01 headings that provides for the seats whether they are convertible to beds or not, and specifically, they are put under the 9401.20 subheading, which provides for the seats of that kind used for the motor vehicles. Because of this, the classification of parts and accessories becomes so challenging. The classification of the new product that was initially not in existence now the relevant tariff was adopted is another big issue that surrounds the classification process. This might be due to the inadequate description that is present on the invoice and the supporting information that can help in the whole process of the classification of the parts and accessories (HS 2002 Classification by Section (Classifications, Commodity Codes, Commodity Description, HS 2002, HS code search), 2017). Some resources might also be limited or unavailable for instance technical information, literature, as well as the classification data among others. Categorization of the relevant stock keeping units (SKUs) to facilitate the decision-making process with respect to forecasting and stock control and to help the managers to focus on important SKUs is yet another challenge. Despite the fact that this is a great challenge in the classification, it has been overlooked and it contributes significantly to the increase in the availability of the parts and accessories thus reducing the inventory costs (Harmonised System 2012, 2017).. The determination of the appropriate tariff term meaning is another big challenge that companies do face in during the classification of the parts and accessories because they need a specific tariff for the particular product by choosing the item number (World Customs Organization, 2017). The item number that is selected is the one that gives the amount of the duty that is to be put on goods. Conclusion Besides the customs tariff codes constituting the international trade language, they are used commonly for domestic taxes purposes like the sales and the consumption taxes of the company. In the current complex environment surrounding trade, classification of products remains to be a big challenge for majority of the companies, and this is because new products are being developed on a daily basis and their classification is becoming very difficult. Companies shouldlook out for new ways through which these challenges may be minimized to cut on the costs management. References Concepts and basics of Harmonised or HSN Codes for GST. (2017).

Epigenetic Mechanisms
Introduction Various scientific epidemiological studies have revealed that most adults are highly prone to diseases, and this exposure is basically associated with adverse environmental conditions including famine (Heijmans et al 17046). This precisely targets those individuals who are prenatally exposed to famine or hunger, which is considered to be one of the environmental co-factors which play a significant role in heredity (Heijmans et al 17046).Advertising We will write a custom essay sample on Epigenetic Mechanisms specifically for you for only $16.05 $11/page Learn More The early developmental stages of an individual especially for the mammalian species, is the most vital and crucial period in which most establishment of the epigenetic mark occurs especially when exposed to harsh environmental conditions. This epigenetic mark can be transferred from parent to the offspring or in other words can be inherited. Mechanisms of epigenetic gene regulatio n Epigenetic inheritance can be defined as a scientific study of inheritable changes in gene expressions, which may occur due to changes occurring on the underlying DNA sequence and which may also occur due to other external mechanisms altering the gene expression (Ghose). Epigenetic inheritance again disqualifies the idea that inheritance only occur via the DNA contrary to genetic inheritance where itââ¬â¢s believed to be so (Ghose). This is because; it has been observed in many occasions that according to genetic inheritance, the parent passes genes to the offspringââ¬â¢s. But when it comes to epigenetic inheritance it is revealed that even the parents acquired life experience can be transferred to the offspringââ¬â¢s in form of epigenetic tags, which can further be passed on down to future generations (Ghose). The other difference between genetic inheritance and epigenetic inheritance is that, despite the fact that the DNA molecule is known to be very stable; it is rarel y subjected to modification contrary to the epigenetic tags which are weak and prone to many changes occurring over a given period of time once itââ¬â¢s subjected to any environmental influence (Ghose). This is the reason as to why twins have slight lifestyle variations though they are monozygotic (arise from one zygote) with identical epigenomes (Ghose). Even though the twins have identical epigenomes, several studies have revealed that these epigenetic tags eventually are considered to undergo changes over a period of time. The major forms of mechanisms that lead to epigenetic modification include DNA methylation and Histone deacetylation or modification (Heijmans et al 17048). Nevertheless, most phenotypic expression carried by offspringââ¬â¢s from the parent can be altered by any heritable gene transcription, which in most cases result to these epigenetic effects (Heijmans et al 17048). Moreover, Histone proteins which are referred to be tiny spherical granules on which th e DNA double helix strand wraps around, will automatically results to visual changes (at the phenotypic stages) in gene expression (Heijmans et al 17048).This is due to the slight changes of the DNA wrapping around the Histone.Advertising Looking for essay on biology?

Get your first paper with 15% OFF Learn More Based on this process ââ¬Å"post translational modification of the long chains amino acidsâ⬠(which are the building units for the Histone) will result in alteration of the shapes of the Histone sphere (Heijmans et al 17048). Furthermore, the DNA strand which may or may not be completely unwound during the normal stages of DNA replication will possibly result to the transfer of the modified Histone to each new copies of DNA produced during the cellular growth stages (Heijmans et al 17048). Furthermore, these new Histone once formed will act as templates initiating and reinforcing any new modifications to be copied to all diff erentiating cells which will remain in this new shape without reverting back (Heijmans et al 17048). Discussion One recent study which sought to investigate the environmental influence which can result in persistent changes of the epigenetic mark was done through a case study which based on individuals who were prenatally exposed to famine. During this period of famine, medical personnel present at that time had kept reliable records of all individuals who were prenatally exposed to hunger, so that they would make a follow up later during the study; in what would later become a cohort study Gestation exposure (Timing) A case study was conducted on sixty two individuals who had previously been exposed to famine during their gestation period, just to investigate and evaluate the influence of timing on DNA methylation; these people constituted the case group of the sample (Heijmans et al 17049). Furthermore, when determining whether IGF2 DMR methylation depended on timing, more studies were conducted on the periconceptional and late exposed groups who were analyzed together in a single model; the results confirmed that periconceptional exposure was basically associated with lower methylation, whereas the late exposure was not (Heijmans et al 17049). This was statistically and significant evidence which revealed presence of interaction between timing and environmental exposure (Heijmans et al 17049). Birth weight Moreover, the mean weight of sixty two individuals who were previously exposed to famine in their late gestation period was measured; it was again proved that the total mean which was calculated was 3126g; 296g lower than the mean of reference births recorded in 1943 in the very same institution which was 3422g (Heijmans et al 17047). This lower birth weights occurred as a result of famine during the previous hunger winter period, not withstanding the fundamental relationship between IGF2 DMR methylation (Heijmans et al 17047). Age association This experi ment was based on determining presence of any correlation between age and IGF2 DMR methylation; comparatively, the 122 control individual analysis revealed that age 10 was identified to be associated with 3.6% low methylation modifications across all the age group sampled. (Heijmans et al 17047).Advertising We will write a custom essay sample on Epigenetic Mechanisms specifically for you for only $16.05 $11/page Learn More Periconceptional exposure of an individual especially to famine was deduced to be associated with variation in IGF2 DMR methylation, which eventually was observed in adulthood among the subjects; to confirm this laboratory analysis was done which validated the findings. The results confirmed that ââ¬Å"all CpG sites except one was significantly less methylated among all quantified periconceptionally exposed individuals as compared to their offspringââ¬â¢s which was at 0.488â⬠(Heijmans et al 17047); consequently, for those si blings not exposed it was observed to be at 0.515. Finally, basing on the results it was deduced that periconceptional exposure was associated with 5.2% lower methylation occurrence which was ultimately independent of sex (Heijmans et al 17047). Hypothesis testing and supportive evidence Basing on the argument, the data provided completely support the hypothesis; that environment strongly contributes to epigenetic inheritance, more supportive evidence is availed when a study on twins was conducted (Ghose). Twins who share identical genes, with similar methylation patterns which have been inherited from their parents, still ended up being so different (Ghose). Furthermore, in most cases; twins who emerged from same zygote (monozygotic twins) exhibited such scenarios where one could suffer from a disease like diabetes or cancer while the other remains perfectly healthy (Ghose). This is attributed to be the impacts of environmental influences, which eventually results in adaptation of different epigenetic variability; this epigenetic variation in terms of methylation pattern arises due to insignificant, ââ¬Å"random changes in DNA methylationâ⬠which collectively accumulates after each cell division causing a major change (Ghose). The most current studies have revealed that these cases of associations between DNA methylation and that of periconceptional exposure during the early developmental stages are also common in modern societies probably because of the present lifestyles coupled with environmental factors. This evidently includes reported cases of over nutrition and assisted reproductive methods and technologies; all being measures which give rise to similar associations Conclusion Though various research studies have been done on the subject matter, there is no conclusive evidence to suggest whether this epigenetic inheritance is real or not; nevertheless most evidence indicate this epigenetic inheritance is possible.Advertising Looking for essay on biology? Let's see if we can help you! Get your first paper with 15% OFF Learn More This is because of the fact that these findings have further explained many strange patterns of inheritance, in which many geneticists have been puzzling on over decades to uncover. The twin evidence discussed in this paper is one such vital proof that shows how epigenetic and DNA methylation can occur catalyzed by environmental influence (Learn.genetics.com). Finally, one most important notation concerning epigenetic inheritance is that the most crucial stage in which the establishment of epigenetic marks can occur is during the early embryonic development stages of the organism. This was practically proved through an experiment carried out on mice, whereby when culturing the preimplantated mice embryo, it was revealed that the epigenetic marks were susceptible to environmental factors especially nutrition during their early days of development.

Investigating the Effect of Lipase Concentration on the Breakdown of F
Investigating the Effect of Lipase Concentration on the Breakdown of F Investigating the Effect of Lipase Concentration on the Breakdown of Fat in Milk INTRODUCTION: Enzymes are proteins which can catalyse chemical reactions without changing themselves. The enzyme lipase breaks down the fat in dairy products such as full-cream milk for people who are lactose intolerant. Lipase acts on its specific substrate, lipids produces fatty acids. If enzyme concentration increases, random collisions between the substrates and active sites of enzyme increase due to the increasing amount of active sites which allow more collisions to happen, so the rate of breakdown of lipids to simpler substances will increase. During the experiment, sodium carbonate solution and pH indicator phenolphthalein will be added ahead of lipase enzyme; when the pH is below 8.2, phenolphthalein will turn from pink to colourless. Sodium carbonate solution is added in order to turn the solution alkaline and the indicator pink then back to colourless after lipase is added to catalyse the chemical reaction and speed up the breakdown of lipids into fatty acid in the milk. Fatty acid prod uced then is going to neutralise the solution with sodium carbonate solution added previously; phenolphthalein will finally turn from pink back to colourless. AIM: In this experiment I will investigate the effect of increasing enzyme concentration on the activity of the enzyme lipase that will be allowed to act on the same amount of milk and the time taken for the phenolphthalein to turn from pink to white compared. HYPOPTHESIS: With higher lipase concentrations, there will be more active sites in the solution to be fit in by the substrates, which means more collisions between the active sites and the substrates and quicker breakdown of lipids in the milk within shorter period of time. At enzyme concentration of 1% or 2%, reactions can happen at a relatively slower pace, with lipids broken down and phenolphthalein turning from pink to white over a relatively longer time period. At 3%, enzyme activity will speed up with lipids broken down and phenolphthalein turning from pink to white over a relatively shorter time period. At 4% or 5%, enzyme activity will happen significantly faster. APPARATUS: 1. Lipase solution at concentration 5% 2. 1 test tube 3. 5 dropping pipettes 4. full-fat milk 5. 4 measuring cylinders of 10ml (0.5ml) 6. 1 stopwatch (1s) 7. 1 stirrer 8. phenolphthalein 9. sodium carbonate solution at 0.5 mol dm3 10. Marker pen 11. distilled water 12. 4 beakers of 200ml (5ml) VARIABLES: Independent Variables: 1. Enzyme concentration- effectiveness of enzyme concentration will be tested at 1%, 2%, 3%, 4%, and 5%. Enzyme lipase at the concentrations of 1%, 2%, 3%, 4% will be made by mixing lipase at 5% and distilled water; all these solutions will be contained in different beakers to keep them pure. In order to make 1% lipase, for each 1ml lipase, 4ml distilled water will be added and poured into a beaker; to make 2% lipase, for each 1ml lipase, 3ml distilled water will be added; to make 3% lipase, for each 1ml lipase, 2ml distilled water will be added; in order to make 4% lipase, for each 1ml lipase, 1ml distilled water will be added. Controlled Variables: 1. Volume of the milk used for every test will be kept constantly at 5ml; substrate concentration will be kept the same since full-cream milk will be used. Different volumes of milk will allow different amount of substrates to be contained in the milk. Therefore, more substrates contained in the milk will take it more time for the enzyme to break all the fats while the amounts of lipase and sodium carbonate solution stay the same. 2. pH of the substrate the identical amount of 7ml sodium carbonate solution, which is alkaline, will be added in the test tube; if not, more or less fatty acids will be produced and needed to neutralise the solution and for the phenolphthalein to turn from pink to colourless. 3. Volume of lipase solution 3ml lipase will be added to for each test. By keeping this the same, the amount of active sites of enzyme will be equal in all the cases, therefore allowing results to be fair. If more were placed in one of the test tubes, then the rate of activity of the enzyme at different concentrations will be wrongly judged, leading to incorrect conclusion. 4. Temperature

Case study and phenomenal study - Essay Example 2). The difference between the two may appear in terms of their applicability. Case study is largely generic in its usage and understanding, the phenomenological study in contrast largely pertains to the cognitive understanding of the human mind, ability and power to reason. Case study would be more important when the previously undertaken models, patterns and policies are addressed and undertaken for purpose of study. The phenomenological study in contrast may be directed towards the educational sector when the role of single unit or single individual is under scrutiny. The kind of research question undertaken and asked for is directly reflective of the nature of research undertaken. If a given question is about a whole scenario and its overall outcome, it can be attributed to the study and assessment in terms of the case study. In case a particular domain has been subjected to determining its influence or finding the potential alternatives, then it would be considered for a different version of research (Schalk, 2009, p
