Biodiversity Essay Example for Free

Biodiversity Essay Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is â€Å"The degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.† (Rutherford) Ecosystem is on the other hand, â€Å" community and its abiotic environment†( Rutherford). Biodiversity exists in every ecosystem, weather it is big one, or just ecosystem of one garden, it has the same importance because without it nature loses its ability to perform major functions needed for life on Earth, as it is oxygen production. Trough this investigation, two different ecosystems will be explored and the level of their biodiversity on certain area. Research question â€Å"To what extend is one ecosystem more diverse than other one?† Hypothesis If ecosystem has more number of species and organisms within those species, it will have higher biodiversity. Justification of hypothesis According to formula for Simpson`s diversity index, D = N (N-1) / ÃŽ £ n (n-1), where N is total number of organisms, while n is sum of individuals within a specie, we can see that sum of all individuals and total number of organisms of particular species affect the biodiversity index. Variables Dependent variable Biodiversity of ecosystem. Dependent variable is key of the study and it will be tested on independent and controllable ones. It will be derived from sufficient collection of data and using Simpson`s index. Finally it is going to be presented as number of species in two different ecosystems. Independent variable Size of area of ecosystem tested, which is going to be presented in m2. This variable does not depend on other ones, and I decided to calculate biodiversity on 3 m2 in both ecosystems, making sure that conditions are same for both. Controllable variables: Time, weather conditions. These variables control the biodiversity index which is going to be derived and will be controlled as I will decide at which time am I going to measure number of species in ecosystem. In my case, it will be beginning of June. As well as I am going to make sure that I measure it on optimal temperature, without rain or strong sun. PROCEDURE Material: * Meter * Paper * Pen * Calculator * Thermometer Procedure Plan is the key point of each procedure. As I already found material needed for beginning of my investigation, I have to decide on two different location for measuring. It is going to be meadow and garden around family house. In both locations, area of measurement is going to be 3 m2 and I am going to make sure that during the measurement in both locations, conditions of temperature are approximately the same. As I labeled the area of 3 m2 in meadow, I will count the number of different species living there. In addition, I will count number of organisms of each specie. While doing that, I will see the temperature on the thermometer. The same procedure is going to be repeated in garden. After collecting all the raw data, it is going to be presented through value of biodiversity index.

On Style :: Style Toward Clarity Elements Writing Essays

On Style Style is a very ambiguous word. Asking the question, â€Å"What is Style?† is almost a philosophical endeavor, comparable with â€Å"What is Truth?† Asking the question, â€Å"What is Good Style?† is even harder. Society’s boundaries are constantly shifting to accept or banish items from the definition, in art and writing specifically. Yet there are certain elements that remain constant in all these changes, and these are the elements that style manuals try to pin down. Before the class reading/blogging project began, I thought of style as the method a writer uses to communicate his/her ideas to the reader. I still do. If the point of writing is to communicate ideas, and the vehicle we use to transport the ideas from our brains to our readers is our STYLE, then the most important element of style is being clear. What I have learned from reading Strunk and White's The Elements of Style and Joseph William's Style Toward Clarity and Grace is that there are a variety of ways to make writing clear. Each book has its own unique approach to the problem of establishing clear communication in print. Strunk and White’s method of attack is from the angle of the writer. The rules outlined in the book focus on the writer’s image of what he is communicating. The rules are designed to help the writer sort through her own thoughts on paper, and extract the essence of what is being communicated. The theory seems to be that clearer writing begets clearer thinking. For example, rule #14 in Strunk and white states "Use the active voice." If we compare the two sentences given in the example; "Do not say: There were a great number of dead leaves lying on the ground. Do say: Dead leaves covered the ground." (S&W 18) we see how the active voice communicates more clearly than the passive. The excess words get in the way of what the writer is trying to say. This is compounded in rule #17, â€Å"Omit needless words.† The passage states that â€Å"Vigorous writing is concise.† (S&W 23) This reference to vigor and other health terms is mirrored in other rules, and is a clue-in to the entire Strunk and White approach to style. Good style to them is a way of thinking, a confidence in thought that lends itself to forceful, clear statements by the writer. Williams Style Toward Clarity and Grace carries on many of the same rules that are laid down in Strunk and White, only with a different approach.

Constitutional Assignment

Introduction Interpretation of the Australian Constitution has undergone significant changes throughout Australia's Constitutional history. To highlight the number of different approaches, this paper will critique the method of constitutional interpretation used In Cole v Whitfield (â€Å"Cole†) with reference to the words â€Å"absolutely free† and compare it to the progressive approach in Rowe v Electoral Commissioner (â€Å"Rowe†). For completeness, this paper will outline any other major branches of interpretation not examined in Cole and Rowe.Then, the discussion will focus on the reasons for regressive as the preferred approach for interpreting the Constitution. Cole v Whitfield – Interpretative Method and Critique The High Court used originality in its interpretation of section 92 in its Judgment in Cole v Whitfield . Kirby defines originality as interpreting the constitution by ‘ascertaining what the words meant according to the original inte ntions of the founders'.Mason refer this as internationals (for the purpose of this paper, It will be referred as original Intent In the unanimous decision, the court overruled the view that â€Å"absolutely free† In section 92 of the Constitution protected a personal individual right of freedom In Interstate trade. Rather It means free trade between the states from measures characterized as ‘discriminatory and ‘protectionist. ‘ In aiding its interpretation, the court relied on historical materials to assist in determining the meaning of section 92 and contextual analysis to further validate their claim.To identify meaning of â€Å"absolutely free†, the court broke with tradition by using Convention draft and debate materials to support their reasoning. The high court said: ‘Reference to history may be made†¦ For the purpose of Identifying the contemporary meaning of language used, the subject to which that language was directed and the nat ure and objectives of the movement towards federation from which the compact of the Constitution finally emerged'.From these historical papers, the court looked at the surrounding circumstances leading up to federation to ascertain whether the purpose of the provision was in line with what they were trying to do; and that is to create a federal system that caters for a unified financial framework. From this, the court said the ‘purpose of the section is clear enough†¦ To create free trade amongst the Commonwealth and states like' and there can be no doubt that ass guarantees absolute freedom †¦ Room all interstate border duties Nevertheless, one of the major critiques of original Intent Is the ability to Identify the founders' Intention. To derive a meaning of the words â€Å"absolutely free† from historical materials predominantly relies on certain assumptions that are inherently flawed, namely ; materials are accurate and intention for unforeseen matters and the lack guidelines to source historical materials. The Convention debates are incomplete and inconclusive. More importantly, it does to include assumptions on how the federal system ought to operate within the common law.Griffith CO in Municipal Council of Sydney v The Commonwealth helpfully said of Convention Debates: ‘They are no higher than parliamentary debates, and are not to be referred to except for the purpose of seeing what was the subject-matter of discussion, what was the evil to be remedied, and so forth. ‘ Additionally, the majority in â€Å"Work Choice Case† observed that: ‘To pursue the identification of what is said to be the framers' intention, much more often than not, is to pursue a mirage.It is a mirage because the inquiry assumes that it is both possible and useful to attempt to work out a single collective view about what is now a disputed question of power, but then was not present to the minds of those who contributed to the debates . ‘ Furthermore, if we assume the Convention Debates are complete, there is no evidence to suggest the framers put in what they intended. The Convention Debate would involve different states coming together and agreeing to be regulated under one system of government.In that process, the states would argue the meaning of he provisions, which power they were prepared to give up and the ones they would sustain post federation. The result would at best be a compromise between their interests and subsequently cannot reflect their true intentions. This is evidenced in the Work Choice Case the majority found the Convention Debates reveal very little about what those who framed the Constitution thought would fall within or outside the power'.Even if we were to take it one step further and assume that the framers did expressed what they truly intended, it is near impossible for them to cater for unforeseen matters that arise in an ever changing society. An example is set in Work Choice Case where the court identified that corporations ‘in the economic life of Australia today is radically different from the place they occupied when the framers were considering †¦ Legislative powers†¦ ‘ and that it was impossible to attribute to them some intention about how this legislative power operates in respect of these or other subsequent legal, economic, and social developments'.Lastly, the validity of the historical materials is disputable insofar as the lack of deadlines on how these materials ought to be sourced. There is no clear historical procedure or method in place to ascertain framers' intention. Little comfort can be derived from getting a genuine intended meaning particularly in assessing which of the sources are relevant and which ones are reliable. This is again demonstrated in the Work Choice Case. This is problematic as differences in historical materials may lead to differences in Judicial views. meaning of the section 92 because it dra ws on the idea of a federal system; this impression is reinforced by the context provided by the surrounding provisions, ass-91 deal with fiscal charges and burdens†¦ Appearing in CHI IV of the Constitution which is headed â€Å"Finance and Trade. The court looked at the provision in context to what the purpose of federation and noted that the meaning of â€Å"absolutely free† has not changed, thus concluded that freedom is to mean free from discriminatory burdens in the protectionist sense between interstate trade and commerce .A major limit in making implications via contextual interpretation is that critique will say that it does not stay true to the text of the constitution. In response o this, it is maintained that the text of the constitution only takes on meaning when it is viewed in the context of the overarching structure and function of the constitution. ‘ A more detailed discussion on contextual analyses in discussed in Rowe below.Rowe v Electoral Commi ssioner (â€Å"Rowe†) In contrast to Cole whereby the whole court unanimously agreed on its interpretation approach, the Judgment in Rowe v Electoral Commissioner provides a range of different constitutional interpretation methods. The French Court has taken on a progressive approach in interpreting the words ‘directly chosen by the people' in sections 7 and 24 of the Constitution. Accordingly, it was held certain provisions in the Commonwealth Electoral Act 1902 (Act) contravened sections 7 and 24 of the Constitution because the right to vote is democratic and is supported and protected by the constitution .Underpinning their progressivism interpretation of the constitution, the majority Judges relied on the implied meaning from the text of the constitution (contextual approach) based on accepted principles of the Constitution and authority of precedent cases. Progressivism (otherwise known as the â€Å"living tree† institutionalism), believes that the court sho uld construe the Constitution ‘so as to bring it into accord with modern needs and exigencies'.It is understandable why the French court opted for a progressivism approach because the words â€Å"chosen for the people† back in the sass would only mean those who were allowed to vote (this excluded women and Indigenous Australians) . The evolution of Australia's democratic society has significantly changed since 1901 as evidenced by Incitement and Jacobs J] in Mckinley and cited by French CO that the right to vote was subject to he common understanding of the time'.It is of the view of the writer that any other interpretation of methods used here could not possibly embrace the modern view of Australian democracy simply because the framers could not have foreseen how democracy evolved over time. Thus, it is not practical to apply a 1900 federation system to modern day society as evidenced by Dean J in Diaphanous v Herald & Weekly Times Ltd; â€Å"The Constitution must be construed as a â€Å"living force† representing the will and the intentions of all contemporary Australians, both women & men, and not as a lifeless declaration of the will and the intentions of men long since dead. Contextual constitution and the principles it was set up to uphold. ‘ With constitutional principles of representative government , democracy and federalism, firmly embedded into our legal system, the Judges relied on implication from the actual text of the Constitution. Thus, â€Å"chosen by the people† should be interpreted to mean creating a system of representative democracy because it is in the context of the Constitution that is aiming to set up .More precisely, the court viewed those words as an implied right to vote. Whilst Cole v Whitfield used contextual analysis, the difference here is with Cole, the implication was based on the structure of the Constitution and in Rowe, the implication was sought directly from the text and that the meaning accords with accepted principles of interpretation. These two kinds of implication are outlined by Mason C. J. In â€Å"Act's†.The majority Judgment relied on precedent to conclude the legislative curtailment of the right to vote is constitutionally invalid. All the members of the court relied on the test established in Lange v Australian Broadcasting Corporation (â€Å"Lange†) and relied upon in Roach. As stated by the High Court in Lange, the requirement set out in section 7 and 24 'embraces all that is necessary to effectuate the free election of representatives at periodic elections'.All of the Judicial consideration of the term â€Å"directly chosen by the people† supports the view that sections 7 and 24 of the Constitution extend to an implied right to vote and this was substantiated by the authority of McKinley v Commonwealth , Mincing v Western Australia , Lang and Roach. It is important to note here, whilst this court relied on the precedent to aid in TTS interpretation, the court in Cole overruled nearly 88 years of law by reinstating the meaning of ass.The dissenting Judges Haynes J and Hoyden J preferred various versions of originality, which is slightly different to Cole v Whitfield internationalist approach. The former (Haynes J) found the ‘evolution of the concept of â€Å"representative government† could not evolve into a constitutional norm' as there was no text and structure' of it contained in the Constitution and the latter relied on what the words originally mean in the sass; that is, the question is what meaning skilled lawyers and other informed observers considered those words to bear in the sass' .He concluded that although suffrage at federation did not conform to modern values, this is not a reason to ignore what the means and applications of the word ‘chosen by the people' in the federation age were'. Is one of these methods of Interpretation preferable to any other? For the purpose of comple teness, there is another interpretative method that is not discussed above and that is Literalism. Craven describes literalism as interpreting the Constitution by their ordinary – that is their literal meaning.This is evidenced in the Engineers case whereby the court overturns the reserve state powers doctrine and held that the states only have residual power over matters in section 51 of the Constitution. The obvious advantage of literalism is that it is â€Å"objective† in the sense that Judges does not need to use external materials thus promotes certainty. The fundamental flaw in this approach firstly it ignores implications and secondly, the English language is by its very nature is ambiguous ambiguity can be overcome by using historical materials to determine the framers intentions.The critics will argue that intention is difficult to identify and does not cater for the progression of a nation . It is asserted here that originality and intentionality does have a role in constitutional interpretation albeit a small role. Sir Daryl Dawson in his (Intention and the constitution) states that original intent ‘provides a starting point for the determination of individual cases. ‘ Progressivism as defined in Rowe (above) allows the constitution to be interpreted to the needs of a contemporary society.One of the main critic of progressivism is that it is arbitrary even unelected Judges can ultimately state what the contemporary society views is. On a closer examination, this supposition is unfounded. Kirby argues that the constitution itself and the words in it create limits on Judicial interpretation. Furthermore he argues that the common law structure is there with a long history of precedents, which has been Written down.. Expositions been duly recorded.. To make up the great body of common law. That is, the Judges still need to work within the common law system in light of the Judgments that went before them.This is slighted in the Engineers case , whereby Knox q, Isaacs, Rich and Starker J said that the Constitution should be read ‘naturally in the light of the circumstances in which it was made, with knowledge of the combined fabric of the common law, and the statute law which preceded it'. The history, common law and text of the constitution itself represents the various constraints that Judges need to work with and thus, cannot be viewed as arbitrary. Conclusion Coles intentionality method of interpretation has many flaws inherent in its approach and by definition does not cater for our contemporary society.This is in contrast to Rowe which adopted a progressivism approach and interpreted the words contingent upon external factors such as the context of the words in the Constitution as a whole and the underpinning values of the modern system and its structural framework. It is likely that history may set the context for the words of the provision and provide a starting point for constitutional interp retation but progressivism is the preferred approach as it encapsulates the needs of a changing society and ensures the interpretation is current, practical and logical.

The Role of Family in Taking Action on Drug Abuse Essay

The Role of Family in Taking Action on Drug Abuse The purpose of this piece of writing is not to compare the different methods of approaching drug prevention, or say what methods are not working. It is to simply state that the more the family takes action or gets involved with each others live, problems such as drug abuse will become obsolete. Many different attempts to lower the drug rate have been in placed by society. But despite years of anti drug campaigns within the school and media, drug abuse amongst teenagers in society continues to rise. At home drug testing and emphasis on anti drugs within the family will prove to lower the use of illegal drugs amongst teens. More and more teenagers are experimenting with illegal†¦show more content†¦In todays society the Federal government has required public schools to teach drug prevention since 1987. Also if you play any sports in high school, students are required to sign a contract stating they will stay drug and alcohol free. Teachers and other authority figures wi thin the school, are constantly preaching against drugs. The fact that the drug rate is so high is causing the government to reexamine the approach they are taking and the substance contained in what they are teaching. Drug tests and rewards serve as a deterrent and as a reason to stay drug free. In Red Deer Alberta students voluntarily participate in drug testing. The students which pass then receive cards which allow them discounts at over one hundred and fifty businesses. If more programs such as this were put into place the drug problem may be lower. But until that has happened we must rest the solution heavily on the shoulders of the family. Children need to be prepared for the world. Educational facilities can only do so much. They can not take the lead in the war against drugs. The family has to. Other organizations have been situated to uniquely fight against drug and alcohol abuse. The Rotarian international organization, with more than one million and one hundre d thousand members, have devoted there time to help support the war on drugs. In fact, in 1992 they approved a ten year emphasis on drug prevention.
