Geographic Information Systems :: essays research papers fc

Geographic Information Systems Geographic information systems (GIS) technology can be used for scientific investigations, resource management, and development planning. For example, a GIS might allow emergency planners to easily calculate emergency response times and effected areas of the ocean during an oil spill based on the spills location. You may ask, what is GIS? In the strictest sense, a GIS is a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information, i.e. data identified according to their locations. Practitioners also regard the total GIS as including operating personnel and the data that go into the system. A geographic information system (GIS) works in a series of steps, First there is the relating information from different sources. If you could relate information about oil spill location to the oceans surface currents, you might be able to tell where to start clean up based on how long the oil has been in the o cean. A GIS, which can use information from many different sources, in many different forms can help with such analyses. The primary requirement for the source data is that the locations for the variables are known. Location may be annotated by x, y, and z coordinates of longitude, latitude, and elevation and any variable that can be located spatially can be fed into a GIS. Several computer databases that can be directly entered into a GIS are being produced by Federal agencies and private firms. Different kinds of data in map form can be entered into a GIS. A GIS can also convert existing digital information, which may not yet be in map form into forms it can recognize and use. For example, digital satellite images can be analyzed to produce a map like layer of digital information about marine life productivity. Likewise, sea-grass data can be converted to map-like form, serving as layers of thematic information in a GIS. Next Step for Geographic information systems (GIS) would be to Capture the data If the data to be used is not already in digital form, that is, in a form the computer can recognize, various techniques can capture the information. Maps can be digitized, or hand-traced with at computer mouse, to collect the coordinates of features. Electronic scanning devices will also convert map lines and points to digits. A GIS can be used to emphasize the spatial relationships among the objects being mapped.

Insanity of Hamlet and Ophelia

Hamlet’s insanity comes from his passion to get revenge and grief over his fathers death, while Ophelia has true and justified insanity. Hamlet has reason behind his madness, he is saddened by his father’s death, planning on how to kill his uncle, and his mind is in a fragile place throughout the play. Ophelia is very naive, defenseless, and loyal to the men in her life. She cannot contend with difficulties that occur during the play such as, her father dying, Hamlet’s attitude towards her, and her lack of judgement. The are both insane yet have different reasons and ranging motives behind their insanity. Hamlet is in a unique situation where he his mother has married his uncle, Claudius, and his father has been murdered by his uncle. He wants nothing but revenge for his father. Hamlet is obsessed with proving Claudius guilty. Hamlet receives a lot of pressure from the ghost of his father to achieve revenge and feels like he has some sort of responsibility to get revenge for his father. Hamlet is hasty, erratic, and does not really think about his actions. When he stabs Polonius thinking that it is Claudius hiding behind the curtains, he does not even bother to look behind the curtain he just does it. His wild elocution and deranged actions upset other characters and set them up for other actions. When Hamlet repetitively acts nastily towards Ophelia she winds up committing suicide . When Hamlet says, â€Å" Get thee to a nunnery! † to Ophelia she even questions Hamlet’s sanity at that point and may have been a contribution to Ophelia’s suicide. Hamlet is also upset with his mother, Gertrude, for marrying Claudius so fast after his fathers death. Hamlet feels betrayed by his mother and is enraged with her. In the play Hamlet tells Gertrude how much better his father was than Claudius and tries to make her promise how much better his father was than Claudius. Hamlet says to Gertrude in Act 3 Scene 4, â€Å"Mother, you have my father much offended. † Hamlet feels like his mother has betrayed his father and is angry. Hamlet makes Gertrude feel guilty for doing this. Ophelia madness is brought upon by her love for Hamlet, her loyalty to men, the death of her father, her lover killing her father, and many other things. Hamlet and Ophelia’s relationship is not based on love, but almost around their insanity. It seems as if Hamlet does not really love Ophelia until she passes and then he finally realizes his true love for her. Hamlet states in Act 5 Scene 1,†I loved Ophelia. Forty-thousand brothers could not with all their quantity of love make up my sum. What wilt thou do for her? †. Ophelia truly loves Hamlet and thinks that Hamlet loves her the same way, she is traumatized by the fact that Hamlet shuns her and is rude to her. While watching the play in the castle Hamlet says to Ophelia, â€Å"That’s a fair thought to lie between maids' legs. † His rude comment to Ophelia causes her to become distraught. Hamlet is a possible cause of Ophelia’s suicide. When she finds out that Hamlet has killed her father she talks in riddles, rhymes, and sings songs about death and virginity. In Act 4 Scene 5 Ophelia sings, â€Å"Larded with sweet flowers which bewept to the grave did not go with true-love showers. † Ophelia is hysterical over the fact that Hamlet had killed her father and this is where she completely loses her sanity. She listens to all the men in her life and follows their commands. Polonius and Laertes tell Ophelia to not see Hamlet and that Hamlet does not love her. Laertes states to Ophelia in Act 1 Scene 3, â€Å"Perhaps he loves you now, and now no soil nor cautel doth besmirch the virtue of his will but you must fear. † Laertes is telling Ophelia that Hamlet only wants her love now and will be done with her later. She believes Laertes and does not think for herself. Ophelia is an unpredictable woman who is confused by the males in her life. Ophelia and Hamlet are both undoubtedly insane, but at times Hamlet is on the brink of sanity. Ophelia is clearly crazy throughout the play. She is wild, emotional, and is operated by others. Hamlet’s madness has a source behind it and is at times a sham to throw off others. He is frazzled by his fathers’ death and getting revenge for his father by killing Claudius. He also is angered over the fact that Gertrude, his mother, married Claudius, his uncle, so quickly. Hamlet states in Act 1 scene 2, â€Å" The funeral baked meats did coldly furnish forth the marriage tables. † He is saying that his mother got married so quickly that the left overs from the funeral could cater the wedding. His relationship with Ophelia tears at his heart. He tells Ophelia that â€Å"a woman’s love is brief† during the play within a play nd makes sexual remarks to her. He is very passionate about his fathers death but not about Rosencrantz and Guildenstern’s death . Hamlet is so enveloped in getting revenge for his father, that he does not even care about the death of his two friends. Hamlet is deep in his plot for revenge against Claudius, he makes himself â€Å"crazy† over it. Hamlet and a few others are the only ones that see the ghost, people who do not see the ghost think Hamlet and the others are mad. Hamlet’s relationship with his mother was ruined after she marries Claudius. He feels betrayed by her and his mind is filled with memories of his father. Hamlet has crude passion and purpose behind his insane feelings. Ophelia is entirely insane. Hamlet’s insanity comes from the passion to get revenge for his father’s murder on Claudius and his mother for getting married so quickly to Claudius. Hamlet and Ophelia are both crazy, but Ophelia is absolutely insane and cannot handle the struggles of life. Hamlet could have possibly gotten over his insanity and dealt with his feelings, but his passion for revenge took him over. They are both insane and unstable people as Shakespeare indicates through their deaths.

The Jamaican Early Childhood Curriculum Education Essay

The Jamaican Early Childhood Curriculum was late crafted. The course of study is built on the rule that kids learn best when content from assorted subjects along with accomplishments from the developmental spheres are integrated in line with the kids ‘s holistic position and experience of the universe. These rules are larning through drama, sequenced acquisition, single acquisition, the practicians ‘ multiple functions, inclusion of all scholars, integrated course of study and the spheres of development, the acquisition environment, appraisal in early childhood, affecting parents and community ( Davies, 2008 ) . While the course of study address assorted aims that need to be met in furthering Early Childhood acquisition and outlines the needed instructions, there are challenges to the execution of the course of study. Broadly talking, these factors are normally internal and external. These factors cut down the effectivity of the course of study and weaken the opportunity of effectual acquisition at the Early Childhood Level. The factors occur as challenges when there is a mismatch between the state of affairs that the course of study was designed to aim and the world. This difference causes the existent acquisition result to divert from the intended acquisition result. The course of study is usually assume that the pupil is runing at a peculiar degree, the pupils parent and environmental background offer a certain degree of support, and the instructor operates at a certain degree. The existent job occurs when the course of study does non provide for â€Å" the bulk instance † of pupil s. Internal factors normally include instructors, pupils, school substructure and resources. Teachers are the driving force of implementing the course of study efficaciously. A instructor ‘s creativeness, capablenesss and making enables him/her to reassign the content of the course of study in a meaningful manner that will link with the diverseness of scholars. Harmonizing to Jalongo and Isenberg ( 2012 ) a instructor ‘s cognition of the kids and the content of the course of study will enable him/her the ability to supply for the kids ‘s strengths and failing, their involvement and to develop the cognition, accomplishments, values, and temperaments they will necessitate to go productive members of the society. Hence the instructor ‘s function in developing the course of study is to determine what kids should larn and how they should larn it. In making so the instructor ‘s methodological analysis is indispensable in brining the course of study alive. Jalongo and Isenberg ( 2012 ) postulate that the instructor schemes and program for acquisition is the yarn that weaves the course of study. This they say is what of learning and the how of instruction. It ‘s hence, imperative that instructors plan for the pupils larning so as to provide for the diverse acquisition manners in their schoolroom. The methodological analysiss that the instructor employs should suit the pupil ‘s ability to derive cognition and develop the necessary accomplishments. Teachers should therefore choose content that are developmentally appropriate to accomplish required learning result. On the other manus a instructor should besides be competent and get acute penetrations on the capablenesss that kids posses in order to provide for holistic development. If this is non achieved so the execution of the course of study would hold fails to provide for the kids demands and development. The cardinal ingredient for any course of study is ever the scholar ( Jalongo and Isenberg, 2012 ) . They posit that a course of study should concentrate on what a kid know and can make and what a kid should cognize and can make. Hence the content of the course of study should take into history the demands, involvement, age and phase of development and the societal and cultural context if the kid. The kid as the scholar possesses the ultimate success of the course of study. This takes into history the abilities, accomplishments, background cognition and exposure /experience that the kid get before come ining the acquisition environment. Harmonizing to Puckett and Diffily ( 2004 ) being cognizant of the differences in kids ‘s development, strengths and challenges will let course of study contrivers and instructors to be after efficaciously in order to run into each kid ‘s developmental demands. Jalongo and Isenberg ( 2012 ) stated that a course of study should see the foll owers, Child development and acquisition, Child needs, abilities and involvement and Social and cultural context in which kids live. The considerations of these will enable the instructors to execute efficaciously within the instruction and acquisition environment. The school substructures and resources play a critical function in the bringing of the school ‘s course of study. External factors normally include parents, place and community. This is another driving force in the execution of the course of study. The importance of parental engagement is cardinal in the success of academic accomplishment. This sets the foundation of the learning attitude that kids carry to the acquisition environment. Support from parents increases the academic accomplishment in ulterior old ages. Burke ( 2010 ) concurred kids whose parents are actively involved in their instruction at an early age aids the nurturing of a kid ‘s instruction and overall development and is one of the nucleus indexs of ulterior accomplishment. It is through this engagement that kids understand and appreciate the importance of a solid instruction. The engagement of parents can interrupt or construct the execution of any course of study. Parents are incognizant of the powerful consequence that have on what and how the content of a course of study is designed and implemented. I strongly believe that parents are the first line of support for all kids. They are the primary beginning of socialisation and set the foundation for formal acquisition to take topographic point. The place is the initial environment for optimum nurturing and it ideally creates a sense of belonging. Admiting that meaningful parental engagement is need it ‘s non a â€Å" one-size fits all † . We have to take into consideration the socio economic position of these parents every bit good as their educational background. The background of these parents particularly in urban environments allows for restriction on the input they can offer to the execution of the course of study. Hence, few or no engagement occurs and the inability to keep instructors accountable for hapless course of study execution is hapless. Burke ( 2010 ) provinces that when parents are involved in the educational procedure of their kids and, as such, they will be able to include or add extra information a nd penetration from their ain personal experiences to instructors in order to back up their kid ‘s acquisition and development. The community is seen as the secondary beginning of socialisation.

Irrational Beliefs Essay

Report on some of your own irrational beliefs that have gotten you off course and lowered your self-esteem. Offer rational beliefs that you can take on to dispute your stinkin’ thinkin’. How will changing your irrational beliefs help you to achieve your academic goals? Our upsets are caused not so much by our problems as by what we think about our problems. When our thinking is full of irrational beliefs, what Ellis calls â€Å"stinkin’ thinkin'†, we feel awful even when the circumstances don’t warrant it, and how we think about the issue in our lives is the real issue. I have a few irrational beliefs myself. These include my fear of public speaking, my fear of how people perceive me, and my personal appearance. In high school I enrolled in a speech class that was required for my diploma. My problem wasn’t remembering what to say but being able to speak in front of a classroom full of people. I shouldn’t have had a problem with it at a ll, considering the classroom was full of people I’ve known my whole life, people I’ve grown up with. I got up in front of the class ready to go, I managed to spit out two sentences then my mind went blank. I was embarrassed, scared of what they would think about me if I were to mess up. Would they call me names? Would they think I wasn’t prepared? Would they think I was dumb, powerless, uncreative, and weak? The only thing I could think to do was run to the nearest exit, so out I went. My teacher had followed me but at that point I had tears in my eyes, I was shaking with sweaty palms. She managed to calm me down, she gave me the rational beliefs that I needed, and she believed in me exactly how I should have believed in myself. It all tied into how I am obsessive over what others think of me, my clothes, my hair, and my shoes. I have the irrational belief that everyone needs to look at me and think that I have everything together. In reality my life is usually a mess but I have those materialist things to hide behind. My weight has always been another irrational belief of mine, constantly calling myself fat, not wearing the clothes I want, looking in a mirror and talking myself down. I gained forty pounds in almost two years. I wasn’t the small delicate girl I used to be and I didn’t think I would ever get back to the point of being happy with my body. In order to change these irrational beliefs I need to fill my mind with rational beliefs, such as I am a great public speaker when I am prepared, I am beautiful and smart with or without materialist things, and lastly if I am unhappy with my body then  I have every right to change it. According to psychologist Ellis, a key to correcting irrational thinking is changing a â€Å"must† into a preference. I can always distract myself from negative, judgmental thoughts by simply telling myself, â€Å"STOP!† Then replace my blaming, complaining, or excusing with something positive. Wisely choosing the thoughts that occupy my mind, as well as avoiding automatic, negative thoughts that undermine my self-esteem will also help. Changing my irrational beliefs will help me achieve my academic goals by giving me the confidence to organize my schedule, and be able to speak in front of people as well as with others.

Assignment 3 Essay Example | Topics and Well Written Essays - 250 words - 2

Assignment 3 - Essay Example Scientists describe dark energy as a form of energy in space that accelerates the expansion of the universe. Evidence of dark energy is through: the supernovae, large-scale structure theory, observational Hubble constant data, late-time integrated Sachs-Wolfe effect and the measurement of the cosmic microwave background (Sarkar, pg33). The proponents of the top down scenario proposed that the structure forms through the collapse of a huge gas cloud and as the cloud collapses the gas forms a rapidly rotating disk which is the galaxy (Sarkar, pg55). The bottom-up scenario, on the other hand, involves the merging of smaller objects to form large ones, which mean that galaxies form by the coalescence of smaller structures to form one huge structure. The age of the earth and formation of the various specular objects is the point of contention among the scientists for many centuries. However, there are features and theories which strongly suggest that the earth is at least a million years old: One of the theories tested is the calculation of the rate at which the salt is delivered to the ocean. The level of salt in river water is small and since most rivers flow into oceans measuring the evaporative concentration of the salts reveals that the age of the earth is more than a million years. The thickness of total sedimentary record divided by the average sedimentation rates also yields the same conclusion that the earth is more than a million years

Bioinformatics and molecular modelling Essay Example | Topics and Well Written Essays - 2000 words

Bioinformatics and molecular modelling - Essay Example Plant lipases are often considered to be involved in regulating certain plant growths and developments (Bos and Laxminarayan, 2011; 42). They are mainly found in seeds where triglycerides are stored in the form of intracellular structures or the oil bodies. Lipases usually hydrolyze triglycerides to fatty acids and glycerol that produces energy needed for seed germination. The plant lapses are usually classified into three main groups with the first group consisting of the triacylglycerol hydrolases that are mainly found in seeds. Their study is vital since they are responsible for seed alteration especially during storage. The second group is the acylhydrolases that are found in various plant tissues. They often exhibit limited specificity for their substrates; therefore, they are unable to hydrolyze triglycerides. However, they are cable to catalyze some esterification processes or reactions (Appel and Feytmans, 2009; p. 68). The profound acylhydrolases include phospholipases A and B, sulfolipases, glycolipases, and monoglyceride lipases. The last group in this category is the phosphorlipases that involve plant metabolism, degradation, and rearrangement. Other than the above classification, the recent studies have led to different classification of lipases based on comparison of the sequences of their amino acid among other fundamental biological and physicochemical properties (Gupta, 2007; 34). This modern classification led to eleven subfamilies. Despite being a member of many protein families, the lipases often have similar architecture that is described by the ?-hydrolase fold. The activities of all lipases often rely on the catalytic triad that is usually fromed by the Asp, Ser, and His residues. In the sequence of the amino acid especially involving ?/? hydrolases, these three residues often follow the user-Asp-His order. Additionally, lipases often share the consensus sequence defined by the Gly-Xaa-Ser-Xaa-Gly where X may be a residue of an amino acid (Bos and Laxminarayan, 2011; p. 33). The three dimensional structure of any protein molecule often provides valuable insight into the molecular function, organization, docking stimulation, and the effective designing of drug experiments. The lack of an experimentally determined crystal structure, the homology modeling may be used to provide an opportunity in obtaining a reasonable 3D model. Currently, the 3D models often provide a perfect means of predicting the structure of biomolecules since it yields models that are suitable for a wide application spectrum that are structurally based thereby providing molecular design for mechanism investigation. The 3D approach is capable of providing a reasonable structure model that is often related to template that shares more than 25 percent sequence identity. An Arabidopsis thaliana lipase model is greatly proposed to investigate the model organism mainly in the plant biology since it is relatively small and and it is genetically tractable genome. Methods The Target and Template Proteins The model is perfect in determining adequate template for the homology modeling for the Arabidopsis thaliana. This sequence allows the alignment of amino acid sequence against the protein data bank (PDB) and this is performed by means of BLAST algorithm. According to the sequence algorithm, both the template (1HLG) and the target share 31 percent of the sequence identity.

Immune Response Against HIV Research Paper Example | Topics and Well Written Essays - 500 words

Immune Response Against HIV - Research Paper Example The immune system is a defense mechanism of a body. This research paper desribes how the immune system works against the invasion and threats of viruses, bacteria and other microscopic organisms recognized as non-self. A good example of a virus that the immune system fights against and is a main focus of this research paper, is HIV (human immunodeficiency virus), which is responsible for causation of AIDS. This research paper gives detailed discussion on the topic and describes a few stages of the fighting against viruses process. During the 1st stage, the phagocytes try to engulf and destroy the non-organic enemies that they detect in the body. Stage II of the fight against viruses takes place after the CD4 have received information concerning foreign invaders in the body. During this stage, the CD4 divides and send signals that activate other components required in the defense system. Terminology of CD4, phagocytes and non-organic are also explained in this research paper. In concl usion, the immune system protects the body from foreigners such as viruses and bacteria. HIV virus is known of invading a human cell and making it a factory for viruses. Its destruction of the HIV virus in the body involves different stages. Phagocytes are involved in destruction of non-organic materials in the body. The macrophages then aid in presenting the information on the virus on their surfaces. The CD-4 then uses the information presented on the surface of the macrophages to activate many soldiers such as killer T-cells.
