Aboriginal Residential Schooling Essay Example for Free

Aboriginal Residential Schooling Essay The Aboriginal people had their culture stripped away, without any consent but by force. They were forced to adapt their lifestyle to the normal, and children put into schools to learn how to behave like the Canadians. The Aboriginal residential schools implemented by the Canadian Government were a cause attempting to destroy their culture (Ravelli Webber, 2010, p.132). The Canadian Government wanted to get rid of all aboriginal culture with no trace of their lifestyle. There was a massive social problem due to the separation of the races. It also raised a huge racist confrontation between the Aboriginal`s and the rest of society. The Aboriginal`s were not treated with any respect or dignity, which caused them to loose respect with our Canadian Government, as they were treated like animals. The Canadian Government did not want any Aboriginal`s to grow up as they were, they did not like the way their lifestyle was, they wanted to destroy their culture. They attempted to destroy their culture in many ways, one of the most obvious methods they used were to put the young children in to residential schools (Ravelli Webber, 2010, p308). These schools taught young Aboriginal children how to live like the Canadian, they were not allowed to do anything that was related to their culture not even allowed to speak their language (Geraldine Marcuse, 1993). The children were punished if they did not follow the rules, these punishments were very abusive as well, but by doing so this enforced the children to follow the rules. These residential schools were very structured and strict. Eventually by staying in these schools, due to all the strict rules, abusive punishments, and them not being allowed to associate with their culture the Aboriginal children forgot their native language (Geraldine Marcuse, 1993). The Canadian Government obviously wanted to get rid of all Aboriginal culture. The residential schools brought up a major problems, it created an immense, massive social problem with in the Aboriginal community and the Canadian society. The young Aboriginal children were stripped away from their parents, probably never even saw them again, these children were discriminated by others and were not even allowed to speak a single word  from their native language (Ravelli Webber, 2010, p132) . As displayed in the video, the young girl that had her period out publicly was put to shame by the nuns and the other children, this caused her to be bullied and discriminated because of natural cause (Geraldine Marcuse, 1993). The video also prescribes the punishment received when the rules were broken, as the elder man describes his pain and the punishments received, he explains that these children were being separated entirely from the religion and culture, causing these children to view of their own nation as an abomination (Geraldine Marcuse, 1993). This problems cause a lot of discrimination, causing many social problems with in the community, the children did not have rights, and could not speak for themselves. This massive social issue with in the Aboriginals was created by the ongoing of the residential schools. Canadian Government might not have been too smart by creating the residential schools as they did not calculate the outcome, these residential schools brought up great vengeance to the Aboriginals they wanted their culture back, in doing so it created a racist confrontation later on. This was a huge relation with the conflict theory. The Aboriginals found a method to bring back their culture by using the method the Canadian`s did, they developed their own Aboriginal schools (Geraldine Marcuse, 1993). These schools would teach the total opposite of what the residential schools taught, these schools were teaching their young children their native language, and bits of their culture, or at least what was left of it (Ravelli Webber, 2010, p309). The difference between the Aboriginal schools and the residential schools were the rules and methods of punishment. The Aboriginals taught in a normal manner, with respect, but in the residential schools it was like prison everything was eventually forced upon. The residential schools also made the Aboriginals to grow this hate for the Canadian Government causing this huge racist dilemma between the two parties. No good really came out of residential schooling, just a very bad racist confrontation in the long run. The Canadian Government stripped all the rights of the Aboriginal people, they got their culture massacred, dealt with force and abusive power, they  practically tried to destroy the Aboriginal culture. The Canadian Government put a lot of effort in this project, they tried to change the Aboriginal people in every way, they wanted those people to behave and change their lifestyle to the modern Canadian lifestyle. The Canadian Government have attempted to destroy the Aboriginal culture by bringing up residential schooling to begin the process of elimination. The Government did not want anything that was Aboriginal culture related left, they wanted to get rid of every bit of their culture. The residential schools cause major discrimination cause a massive social problem within the Aboriginal people. These residential schools also raised a huge racist confrontation to the Aboriginals, it separated them from the rest of the society. These schools really have destroyed most of their culture, and was a very cruel method in doing so. The Aboriginals deserved to be heard and have their own rights and freedom.

Why did King Victor Emmanuel II invite Mussolini to power in October 1 :: essays research papers

"Fascism...was a super-relativist movement with no fixed principles, ready for almost any alliance." (Denis Mack Smith in 'Mussolini' - 1981) Background Italian unification was in 1861, from this point up until Mussolini came into power in 1922 Italy was ruled by 'parliamentary liberals.' Liberals had never solved the problems of the economically backward South, therefore they were resented there. It can be suggested that the liberal regimes did little to raise the standard of living for the majority of Italians. Mussolini was a 'renegade socialist' with a strong desire for power. His aims and doctrine were difficult to pin down. He was intolerant and embraced violence, therefore diametrically opposed liberalism. Mussolini's Rise to Power Mussolini's fascist regime (an extreme change for the nation from years of liberalism) took control without any substantial opposition. There were many factions in Italian politics who absolutely opposed fascism but a 'united front' was never formed as the Communists, Socialists and the Catholics had too many unresolved differences with each other. They were too busy arguing amongst themselves to agree to fight fascism together, the one way they could defeat it. D'Annunzio's regime in Fiume had openly defied the liberal government and had been well supported by military officers and sections of the ruling classes. Mussolini witnessed this popular appeal to nationalism with great interest. Mussolini realised towards the end of 1920 that he had to make deals with certain parts of his opposition in order to succeed in parliament. Mussolini embraced the political right (despite his left wing background) as he knew it would unite his own party whose strength would appeal to many in Italy who had completely lost faith in the weak liberal government. Mussolini was an opportunist who gained the support of different parties with calculated concessions. For example, before the election of May 1921 he made 'conciliatory gestures' towards the Catholic Church. His turn away from the left had meanwhile also attracted many liberals who feared a Marxist revolution more than anything. Thus, as Mussolini looked like restoring the proper rule of law (rather than instigating a revolution) they began to see his accession as not so awful after all. He appealed to the Conservatives by assuring them that he was primarily in favour of the concepts of war and empire with far less emphasis on revolutionary tendencies. Mussolini had originally been a Republican but in a speech on the 20 September 1922 he 'grudgingly' accepted the monarchy. He knew that he must do this to get to power as although many in the military supported him their primary allegiance was to the throne.

Biofilm-Mediated Enhanced Crude Oil Degradation by

International Research Journal of Environment Sciences________________________________ ISSN 2319–1414 Vol. 2(2), 48-52, February (2013) Int. Res. J. Environment Sci. Isolation, Characterization and Identification of Diesel Engine Oil Degrading Bacteria from Garage Soil and Comparison of their Bioremediation Potential Teli Nikhil1, Verma Deepa2, Gavankar Rohan1 and Bhalerao Satish3 1 Department of Biotechnology, Viva College, Virar (W), Maharashtra, INDIA 2 Department of Botany, Viva College, Virar (w), Maharashtra, INDIA 3 Department of Botany, Wilson College, Mumbai, Maharashtra, INDIA Available online at: www. sca. in Received 30th November 2012, revised 12th January 2013, accepted 25th January 2013 Abstract The rate of biodegradation of diesel engine oil by microorganisms isolated from garage soil (petroleum contaminated soil) was studied. Modified diesel engine oil medium was used and two most abundant microorganisms were isolated from garage soil – Micrococcus sp. and Pseudomonas sp. were found to be hydrocarbon degraders and these two bacteria’s were selected for the degradation test. The degradation of diesel engine oil was monitored at a five day interval up to twenty five day period, using gravimetric method.After 25 days of incubation period, Pseudomonas sp. degraded 67. 57 % of the oil and Micrococcus sp. with 52. 95 %. But the mixture of Micrococcus sp. and Pseudomonas sp. were found to have great potential to degrade diesel engine oil i. e. 89. 98 % after 25 days. The rate of degradation of diesel engine oil by Micrococcus sp. was found to be 7. 48 x 10-4gm/hr and that of Pseudomonas sp. was 9. 55 x 10-4gm/hr while the mixture of both bacterial isolates showed highest rate of degradation of diesel engine oil i. e. 1. 27 x 10-3gm/hr.Keywords: Bioremediation, Diesel engine oil, oil spills, hydrocarbon degraders, Micrococcus sp. , Pseudomonas sp. Introduction As we dig deeper into the modern industrial age of technologies, several aspects of human life change. People benefit largely from life development and many live in prosperity, but prosperity has a price. This price is paid by our environment that suffers daily from all kinds of pollutants and destruction. People now have to find ways to cure this destruction. Oil contamination is one of the most dangerous pollution factors known today.It can cause a threat to the environment. It is very feared by environmentalists and it's very hard to control if it gets out of hand. Oil spills have been a major issue across decades. One of the famous oil spills which are also ongoing is in Taylor Energy Well in Gulf of Mexico, U. S. A caused due to Hurricane; Sept 16, 2004 till present date and almost 0. 03- 0. 05 tones oil/per day is estimated to leak. Another recent oil spill was in Mumbai (India) and caused due to the leakage in Mumbai-Uran pipeline dated January 21, 2011 and about 55 tons of oil was leaked in Arabian Sea.Various such accidents occur throughout the years and it causes damage to our surrounding. Diesel engine oil, which is one of the major products of crude oil, constitutes a major source of pollution in our environment. With the combined dependence on diesel engine oil by some vehicles and generators, greater quantities are being transported over long distances. Therefore diesel engine oil can enter into the environment through wrecks of oil tankers carrying diesel oil, cleaning of diesel tanks by merchants, war ships carrying diesel oil and motor mechanics1. Diesel oil spills on agricultural land generally reduce plant growth.Suggested reasons for the reduced plant growth in diesel oil contaminated soils range from direct toxic effect on plants2 and reduced germination to unsatisfactory soil condition due to insufficient aeration of the soil because of the displacement of air from the space between the soil particles by diesel engine oil3. Among several clean–up techniques available to remove petroleum hydrocarbons fr om the soil and groundwater, bioremediation processes are gaining ground due to their simplicity, higher efficiency and cost–effectiveness when compared to other technologies4.This study was therefore designed to monitor the rate of biodegradation of diesel engine oil (hydrocarbon) by microorganisms isolated from garage soil (petroleum contaminated soil), by using gravimetric method. Material and Methods Preparation of modified diesel oil medium: The modified diesel oil medium comprised of 0. 7 gm K2HPO4, 0. 1 gm (NH4)2SO4, 0. 3 gm KH2PO4, 0. 3 gm MgSO4 7H2O, 2. 2 gm agar – agar5. The mineral components of the medium were dissolved in 100 ml of distilled water and mixed with 2 ml of Gulf diesel engine oil. The medium was autoclaved at 121oC for 15 min. International Science Congress Association 8 International Research Journal of Environment Sciences______________________________________________ ISSN 2319–1414 Vol. 2(2), 48-52, February (2013) Int. Res. J. Envir onment Sci. Enrichment of microorganisms: Microorganisms capable of degrading diesel engine oil were enriched in sterile modified diesel engine oil medium by inoculating soil (which was collected from Maharashtra garage, 65 years old garage at Sewri) in to the medium in 250 ml conical flask. 0. 5 gm of this garage soil was inoculated in to the 100 ml of sterile modified diesel oil broth and allowed to incubate at 37oC for 1 week.Isolation of microorganisms: After 1 week of incubation period, 1 drop of enriched culture was spread on to the sterile modified diesel oil agar plate. The plate was incubated at 37oC for 48 hr. After 48 hr incubation; two different bacterial colonies were selected from incubated plate. Each bacterial colony type was sub cultured repeatedly onto sterile nutrient agar plates to obtain a pure culture. Pure cultures of bacterial isolates were identified on the basis of their colonial morphology, cellular morphology and biochemical characteristics according to t he taxonomic scheme of Bergey’s Manual of Determinative Bacteriology6.Determination of microbial colony numbers for degradation studies: 5 ml of sterile Nutrient broth was aseptically inoculated with a loopful of pure culture of Colony 1(C1) in first test tube and Colony 2 (C2) in second test tube and incubated both the tubes at 37oC for 24 hr. After incubation, the numbers of organisms present in one ml of nutrient broth were determined by spread plate method. The numbers of organisms were adjusted in both the tubes in such a way that both the isolates contain approximately equal numbers of microorganism in one ml of sample by using sterile Nutrient broth as a diluent7.Soil sample collection and preparation: Top surface soil sample was collected from the premises of the Shahid Bhagatsingh Ground, Kalachowki; in sterilized plastic containers. Soil sample meant for degradation studies was sterilized using autoclave at 121oC for 15 min, after which it was allowed to cool to roo m temperature for further treatments. Description and treatment of samples: Test: i. 12 samples of 15 gm sterilized soil mixed with 1 ml (0. 848 gm) of Sterile Gulf diesel engine oil + 0. 2 ml culture of C1, ii. 12 samples of 15 gm sterilized soil mixed with 1 ml (0. 48 gm) of Sterile Gulf diesel engine oil + 0. 2 ml culture of C 2, iii. 12 samples of 15 gm sterilized soil mixed with 1 ml (0. 848 gm) of Sterile Gulf diesel engine oil + 0. 1 ml culture of C1+ 0. 1 ml culture of C 2 Control: 12 samples of 15 gm sterilized soil mixed with 1 ml (0. 848 gm) of Sterile Gulf diesel engine oil + 0. 2 ml of sterile distilled water. Diesel oil degradation studies: The ability of C1, C2 and mixture of both the bacterial isolates to degrade diesel oil was monitored on the first day (day zero) of the study and subsequently at 5-day interval for 25 days.Carbon tetrachloride was employed as an extractant. On each day, two samples per single treatment were analyzed for the quantity of residual dies el oil7. Each of the 15gm soil treatment samples was mixed with 40 ml of carbon tetrachloride, placed in a separating conical flask, shaken vigorously for 3 min and allowed to settle for 5 min. The liquid phase was separated by allowing the supernatant (diesel oil – carbon tetrachloride) to pass gradually through a funnel fitted with filter paper (Whatman No 1). Anhydrous sodium sulphate spread on the filter paper was employed to remove any moisture in the mixture.The liquid phase was collected in a 50-ml pre-weighed beaker. The beaker containing the extract was placed in an oven and the extractant allowed to evaporate at 50oC. The beaker with the residual diesel oil was allowed to cool to room temperature and weighed to determine the quantity of residual diesel oil by difference8. Results and Discussion In this study, the soil samples were gathered from the garage (oil contaminated site) because the capability of native bacterial population to mineralize crude oil hydrocarbo ns in oil contaminated sites was confirmed before by many scientists9.The rate of biodegradation of Diesel engine oil by hydrocarbonoclastic organisms isolated from garage soil were assessed. Table – 1 and table – 2 shows that, using cultural characteristics and biochemical characteristics, two bacterial isolates; Micrococcus sp. and Pseudomonas sp. were identified by compairing it with the Bergey's manual of determinative bacteriology. The number of CFU/ml of both the bacterial isolates was adjusted to 7. 88 x 107 CFU/ml for degradation studies. The biodegraders which were Micrococcus sp. , Pseudomonas sp. and Mixture of both the culture showed different abilities in the breakdown and utilization of the diesel engine oil.

Res. J.Environment Sci. Diesel engine oil degradation study by Micrococcus sp: It was seen that the rate of diesel oil degradation by Micrococcus sp. was slow as compared to the rate of degradation of diesel oil by Pseudomonas sp. and mixture of Micrococcus sp. and pseudomonas sp. But the diesel oil degradation potential of Micrococcus sp. was continuously increasing as the time of contact between oil and organism increased. D iesel engine oil degradation study by Pseudomonas sp: It can be seen that the efficiency of Pseudomonas sp. to degrade diesel engine oil is faster than that of Micrococcus sp.As the incubation period increases the rate of degradation of diesel engine oil also increases. But it was seen that till 15th day, the rate of degradation was much faster. This was probably due to the exponential phase of the cell growth but after that the rate of degradation was slightly decreased. It was possibly because of cells of the Pseudomonas sp. were near to its stationary phase of cell growth. Diesel engine oil degradation study by mixture of Micrococcus sp. and Pseudomonas sp: The weight of diesel oil extracted from soil containing diesel engine oil and mixture of both bacterial isolates i. . Micrococcus sp. + Pseudomonas sp. showed continuous weight loss till the 25th day of incubation period. After 5th day of incubation period it was seen that there was a drastic increase in the rate of diesel oil degradation till the 25th day of incubation period which was quite higher than that of the single culture of Micrococcus sp. as well as that of the Pseudomonas sp. In this case it was found that around 90% of the diesel engine oil was degraded after 25th day and rate of degradation of diesel oil was found to be continuously increasing i. e. 1. 50 x 10-4gm/hr after 5th day to 1. 7 x 10-3gm/hr after 25th day. Conclusion When Micrococcus sp. is used in combination with Pseudomonas sp. it showed a great potential to diesel oil degradation. This was probably due to the different enzyme system from two different bacterial isolates that acts on hydrocarbon at a time which proved to be an excellent option to degrade that hydrocarbon if both the bacterial enzyme system posses considerable efficiency to act upon it and to degrade it10. This was followed by single culture of Pseudomonas sp and then Micrococcus sp. The oil degradation by Pseudomonas sp. as not surprising not only because it wa s isolated from garage soil which was already contaminated by oil and grease but also because it is known to possess a more competent and active hydrocarbon degrading enzyme system than Micrococcus sp. It is known to be fast growing and is capable of degrading a wide variety of organic compounds11. In the case of Micrococcus sp. which is also known to posses the considerable efficiency to use it as an oil degrader, but it requires more time compared to that of the Pseudomonas sp. Figure–1 Comparison of % Diesel engine oil degradationInternational Science Congress Association 51 International Research Journal of Environment Sciences______________________________________________ ISSN 2319–1414 Vol. 2(2), 48-52, February (2013) Int. Res. J. Environment Sci. Figure–2 Comparison: Rate of Diesel engine oil degradation (gm/hr) By using biological processes, as in the case of bioremediation, usually lowers the costs as compared to chemical treatment processes for variou s contaminated sites. It is also less disturbing to the environment. However, because it is a natural process, it requires time.The above experiment shows that bioremediation can be used effectively to treat oil contaminated soil. The remarkable rate of diesel oil degradation by bacterial isolates shown by this method allows for the safe and convenient use of this microorganism in the oil contaminated area. Moreover the results obtained from the comparison between the diesel oil degrading ability of Pseudomonas sp. , Micrococcus sp. and mixture of both helps them to use in different bioremediation processes based upon their efficiencies. And the advantages of employing mixed cultures as opposed to pure cultures in bioremediation have been demonstrated. . 3. Baker J. M. , Mangroove swamps and the oil Industry, Environ. Pollut.

William Of Ockham And David Hume - 931 Words

Question: Discuss the fascinating parallels between William of Ockham and David Hume, highlighting for example, the Regularist View of Causality. Answer: David Hume William of Ockham Hume did not deny causation. He embraced it. But he did say that empirical methods could not logically prove its necessity, as observations only show a constant conjunction of events, a regular succession of A followed by B, which leads the mind to the inference of cause and effect. For Hume, causality is something humans naturally believe. Ockham readily grants that if the world has to be â€Å"held up† by conserving causes, then there must be a first among them because otherwise the set of conserving causes would constitute an uncountable quantity of actually existing things. It is in fact a tenet of belief that God is both an efficient and conserving cause of the cosmos, and Ockham accepts this tenet on faith. We cannot logically know or prove causation and matters of fact, as we can know and prove the relations of ideas such as mathematics and logic. But we have a natural belief in causation and in many matters of fact. There would be an infinite regress among causes if there were not a first cause; therefore, there must be a first cause, namely, God. If the chain of efficient causes that have produced the world as we know it today had no beginning, then it would form, not an extensive infinity, but an intensive infinity, which is harmless.
