Free Will and Divine Foreknowledge Essay Free will is the ability to make our own choices in issues regarding all aspects of life. It is a power that enables us to make our own choices that are not affected by external factors such as divine will. Therefore, each one sins by his/her own will. While, divine foreknowledge is the fact that God has complete knowledge of what will happen in the future. In â€Å"On Free Choice of the Will†, St. Augustine discusses a critical issue which is the incompatibility of man’s free will and God’s foreknowledge. So the question is, do we really have free will in spite of the fact that God foreknows everything? If God knows what must necessarily happen next, then how do have the free will to make our own choices? Augustine comes up with a series of arguments to prove that we sin by our own will with no intervention of the divine foreknowledge. Augustine first argued a characteristic of God that He has free will, and that He has foreknowledge of his own actions. Therefore, both God’s will and foreknowledge go along with each other. From this point he then assumes that man’s will and God’s foreknowledge are both compatible. But can we compare God with man? And is this argument convincing enough? More elaboration has to be given in order to make it more convincing. Augustine then proceeds to do so. He states that people who do not believe in the compatibility of free will and divine foreknowledge are those who â€Å"are more eager to excuse than confess their sins† (p. 73). That means that people who always blame others for their own wrong doings rather than admitting it are those who claim that we have no free will and that everything is already known by God, and that nothing can be changed, which they also use as a justification for their wrong actions. These people live their life by chance, leaving everything according to the circumstances rather than trying to take good actions. An example for that is the beggars, who always try to take money from people without giving anything in return or even having a job, although they have the ability to do so. But because of their laziness and their belief that this is what they were created to be, they leave everything to happen by luck and according to God’s foreknowledge that couldn’t be changed (p. 73). Augustine then moves to another point which is the relation between the will and the power to achieve that will. He states that the will itself is within our power. Therefore, our desire to commit certain acts is a power that we own. But if we will something that is not within our power then it is not considered as a will because we can only will what is within our power. Augustine then discusses that if something good happens to us then it is accordance to our will, not against it. So for example, being happy, although God foreknows that you will be so, doesn’t mean that we are happy against our will. Thus, God’s foreknowledge of our happiness doesn’t take away our will to be happy (p. 76). And so, he concludes that if God foreknows our will, then definitely this will is going to occur, and so it will be a will in the future. Consequently, his foreknowledge doesn’t take away our will. And since that what we will is in our power, God foreknows our power and He will not take it away. Hence, we will have that power because God foreknows it (p. 77). So Augustine made it clear â€Å"that it is necessary that whatever God has foreknown will happen, and that he foreknows our sins in such a way that our wills remain free and are with in our power† (p.77). However, the fact that God’s foreknowledge of our sins is consistent with our free will in sinning still stays questionable. Taking into consideration the fact that God is just, so how does He punish our sins that happen by necessity? Or is God’s foreknowledge not an obligation? The topic is still confusing so Augustine then proceeds to make it clearer. He explains that if we are certain that someone is going to sin, then we have foreknowledge with the wrongdoing that he/she is going to commit. This foreknowledge didn’t force them to do so, but it was done by their own free will. Accordingly, their will to sin is consistent with our foreknowledge of that sin. Therefore, â€Å"God forces no one to sin, even though he foresees those who are going to sin by their own will† (p. 78). Augustine then compares foreknowledge with memory. He states that our â€Å"memory does not force the past to have happened†, and similarly God’s foreknowledge of the future doesn’t force it to occur (p. 78). And we remember things in the past that we have done but didn’t do everything that we remember, likewise God foreknows everything that He will cause in the future, but doesn’t cause everything that is within His foreknowledge (p. 78). As a result, God punishes our sins that we do by our own will and which He did not cause, as God is known by his justice. Augustine then comes up with a good argument for all those who are still slightly confused, that if God should not punish us for our sins that He foresees then He also shouldn’t reward us for our good work that He also foresees (p. 78). To conclude, Augustine succeeded in coming up with a good argument showing that man’s free will and God’s foreknowledge are both compatible. The sequence of his ideas made his argument understandable and convincing for any reader. As a reader, I’ve always thought about that subject but didn’t receive any answers. However, reading â€Å"On Free Choice of the Will† made everything clear for me and made me well convinced that God’s foreknowledge doesn’t intervene with our own choices that we make.

Direct Hydration Reacts Propene And Water Environmental Sciences Essay

Direct Hydration Reacts Propene And Water Environmental Sciences Essay Being a secondary alcohol, isopropyl alcohol can be oxidized to acetone, which is the corresponding ketone. This can be achieved using oxidizing agents such as chromic acid, or by dehydrogenation of isopropyl alcohol over a heated copper catalyst: (CH3)2CHOH ? (CH3)2CO + H2 Isopropyl alcohol is often used as both solvent and hydride source in the Meerwein-Ponndorf-Verley reduction and other transfer hydrogenation reactions; it is oxidized to acetone. Isopropyl alcohol may be converted to 2-bromopropane using phosphorus tribromide, or dehydrated to propene by heating with sulfuric acid. Like most alcohols, isopropyl alcohol reacts with active metals such as potassium to form alkoxides which can be called isopropoxides. The reaction with aluminium (initiated by a trace of mercury) is used to prepare the catalyst aluminium isopropoxide.[3] Isopropanol becomes increasingly viscous with decreasing temperature. At temperatures below -70C isopropanol resembles maple syrup in viscosity. [edit]Production In 1994, 1.5 million tonnes of isopropyl alcohol was produced in the United States, Europe, and Japan.[4] This compound is primarily produced by combining water and propene in a hydration reaction. Of minor significance is the hydrogenation of acetone.[4][5] There are two routes for the hydration process: indirect hydration via the sulfuric acid process, and direct hydration. The former process, which can use low-quality propene, predominates in the USA while the latter process, which requires high-purity propene, is more commonly used in Europe. These processes give predominantly isopropyl alcohol rather than 1-propanol because the addition of water or sulfuric acid to propene follows Markovnikovs rule. Indirect hydration The indirect process reacts propene with sulfuric acid to form a mixture of sulfate esters. Subsequent hydrolysis of these esters by steam produces isopropyl alcohol, which is distilled. Diisopropyl ether is a significant by-product of this process; it is recycled back to the process and hydrolyzed to give the desired product.[4] Direct hydration Direct hydration reacts propene and water, either in gas or liquid phases, at high pressures in the presence of solid or supported acidic catalysts. Higher purity propylene (> 90 %) tends to be required for this type of process.[4] Both processes require that the isopropyl alcohol be separated from water and other by-products by distillation. Isopropyl alcohol and water form an azeotrope and simple distillation gives a material which is 87.9% by weight isopropyl alcohol and 12.1% by weight water.[6] Pure (anhydrous) isopropyl alcohol is made by azeotropic distillation of the wet isopropyl alcohol using either diisopropyl ether or cyclohexane as azeotroping agents.[4] Hydrogenation of acetone Crude acetone is hydrogenated in the liquid phase over Raney nickel or a mixture of copper and chromium oxide to give isopropyl alcohol. This process is useful when coupled with excess acetone production, such as the cumene process.[4] [edit]Uses In 1990, 45 thousand tonnes of isopropyl alcohol were used in the United States. The vast majority of isopropyl alcohol was used as a solvent for coatings or for industrial processes. Isopropyl alcohol in particular is popular for pharmaceutical applications,[4] presumably due to the low toxicity of any residues. Some isopropyl alcohol is used as a chemical intermediate. Isopropyl alcohol may be converted to acetone, but the cumene process is more significant. In that year, a significant fraction (5.4 tonnes) was consumed for household use and in personal care products. It is also used as a gasoline additive.[4] [edit]Solvent Isopropyl alcohol dissolves a wide range of non-polar compounds. It also evaporates quickly and is relatively non-toxic, compared to alternative solvents. Thus it is used widely as a solvent and as a cleaning fluid, especially for dissolving oils. Examples of this application include cleaning electronic devices such as contact pins (like those on ROM cartridges), magnetic tape and disk heads (such as those in audio and video tape recorders and floppy disk drives), the lenses of lasers in optical disc drives (e.g. CD, DVD) and removing thermal paste from heatsinks and IC packages (such as CPUs.[7]) Isopropyl alcohol is used in keyboard, LCD and laptop cleaning, is sold commercially as a whiteboard cleaner, and is a strong but safer alternative to common household cleaning products. It is used to clean LCD and glass computer monitor screens (at some risk to the anti-reflection coating on some screens[citation needed]), and used to give second-hand or worn non-vinyl phonograph records newer-looking sheen. Isopropyl alcohol should not be used to clean vinyl records as it may leach plasticizer from the vinyl making it more rigid[citation needed]. It is effective at removing residual glue from some sticky labels although some other adhesives used on tapes and paper labels are resistant to it. It can also be used to remove stains from most fabrics, wood, cotton, etc. In addition it can also be used to clean paintballs or other oil based products so that they may be reused, commonly known as repainting. It is used as a wetting agent in the fountain solution used in lithographic printing, and often used as a solvent for French polishing shellac used in cabinet making. [edit]Intermediate Isopropyl alcohol is esterified to give isopropyl acetate, another solvent. It reacts with carbon disulfide to give sodium isopropylxanthate, a weed killer. Isopropyl alcohol reacts with titanium tetrachloride and aluminium metal to give titanium and aluminium isopropoxides respectively, the former a catalyst, and the latter a chemical reagent.[4] This compound may serve as a chemical reagent in itself, by acting as a dihydrogen donor in transfer hydrogenation. [edit]Medical Disinfecting pads typically contain a 60ÃÆ' ¯Ã‚ ¿Ã‚ ½70% solution of isopropyl alcohol in water. A 75 % v/v solution in water may be used as a hand sanitizer.[8] Isopropyl alcohol is used as a water-drying aid for the prevention of otitis externa, better known as swimmers ear.[9] [edit]Automotive Isopropyl alcohol is a major ingredient in gas dryer fuel additives. In significant quantities, water is a problem in fuel tanks, as it separates from the gasoline, and can freeze in the supply lines at cold temperatures. It does not remove water from gasoline; rather, the alcohol solubilizes water in gasoline. Once soluble, water does not pose the same risk as insoluble water as it will no longer accumulate in the supply lines and freeze. Isopropyl alcohol is often sold in aerosol cans as a windscreen de-icer. Isopropyl alcohol is also used to remove brake fluid traces from hydraulic braking systems, so that the brake fluid (usually DOT 3, DOT 4 or mineral oil) does not contaminate the brake pads, which would result in poor braking. [edit]Laboratory As a biological specimen preservative, isopropyl alcohol provides a comparatively non-toxic alternative to formaldehyde and other synthetic preservatives. Isopropyl alcohol solutions of 90ÃÆ' ¯Ã‚ ¿Ã‚ ½99% are used to preserve specimens. Isopropyl alcohol is often used in DNA extraction. It is added to a DNA solution in order to precipitate the DNA into a pellet after centrifuging the DNA. This is possible because DNA is insoluble in isopropyl alcohol. [edit]Safety Isopropyl alcohol vapor is denser than air and is highly flammable with a very wide combustible range. It should be kept away from heat and open flame. When mixed with air or other oxidizers it can explode through deflagration.[10] Isopropyl alcohol has also been reported to form explosive peroxides.[10][11] Like many organic solvents, long term application to the skin can cause defatting.[12] [edit]Toxicology Isopropyl alcohol and its metabolite, acetone, act as central nervous system (CNS) depressants. Symptoms of isopropyl alcohol poisoning include flushing, headache, dizziness, CNS depression, nausea, vomiting, anesthesia, and coma. Poisoning can occur from ingestion, inhalation, or absorption; therefore, well-ventilated areas and protective gloves are recommended. Around 15 g of isopropyl alcohol can have a toxic effect on a 70 kg human if left untreated.[13] However, it is not nearly as toxic as methanol or ethylene glycol. Isopropyl alcohol does not cause an anion gap acidosis (in which as lowered blood serum pH causes depletion of bicarbonate anion) unlike ethanol and methanol. Isopropyl alcohol does however, produce an osmolal gap between the calculated and measured osmolalities of serum, as do the other alcohols. Overdoses may cause a fruity odor on the breath as a result of its metabolism to acetone, which is further metabolized to produce the nutrients acetate and glucose.[14] Isopropyl alcohol is oxidized to form acetone by alcohol dehydrogenase in the liver.

The Catcher In The Rye :: essays research papers

In 1964, J.D. Salinger composed a novel titled The Catcher in the Rye that became quite controversial and was banned from several schools because of inappropriate content. The story is pretty dramatic, but it has many comical incidents. The book is trying to project the idea that you can run from your problems as much as you want; however it is inevitable that you face them. You can’t run forever! If this were a scary movie, the evil laughter would start now. Our main character Holden Caulfield at first appears to be having a conflict with society, but, upon closer examination, we see he is truly only at war with himself. Our story starts with Holden being kicked out of yet another school, this time Pencey Prep, for failing four classes. He is supposed to go home at Christmas Break and not return, however, things don’t work out like that. A situation progresses into a first fight when Holden finds out that his roommate had sex with a girl named Jane Gallagher, who it becomes apparent that Holden loves. Holden loses the fight and grabs his bags and hunting hat and heads for the train station a few days early. One conflict is Holden deciding how to tell his parents that he was kicked out of Pencey. Another less obvious conflict is Holden dealing with the people around him without getting the urge to blow up a building. He is completely convinced that everyone in the world is a phony, except for his little sister Phoebe, Jane, and himself. Throughout the story, he is plagued by phony people. These two problems connect when Holden is attempting to plan his future away from such phonies and do it without his parents finding out about Pencey. After he leaves Pencey, Holden takes a train to New York, where his only plans are to plan to make plans. He meets all sorts of people in New York, including a ditsy blonde named Bernice at the Lavender Room. He buys a hooker named Sunny from a guy named Maurice, but pays her just for talking. There’s a mix-up about the payment, so Maurice beats him bloody. He goes to see a show with a girl named Sally Hayes and wants to run away with her, then decides she’s phony, so he leaves her at a diner. He meets an old friend named Luce for drinks and ends up getting drunk and embarrassing himself by calling Sally.

A Critical Pr?cis of ?The Mystery of Persons and Belief in God by C. S :: essays research papers

A Critical Prà ©cis of â€Å"The Mystery of Persons and Belief in God by C. Stephen Evans 1.  Ã‚  Ã‚  Ã‚  Ã‚  Name of author, title, appropriate publishing information, followed by a verb such as argues, believes, reports, and finally a â€Å"that clause containing the author’s thesis or major assertion. In â€Å"The Mystery of Persons and Belief in God† from the web site http://www.orgins.org/articles/evans_mysterypersons.html, C. Stephen Evans asserts that if we examine human nature and desires with a Christian mindset, we will discover good reasons for believing in God. 2.  Ã‚  Ã‚  Ã‚  Ã‚  A brief explanation (one paragraph or less) how the author supports and develops his or her thesis.   Ã‚  Ã‚  Ã‚  Ã‚  Mankind’s evil deeds point to our greatness, for only a creature with self-consciousness and freedom can be truly evil. We are created in the image of God and we were created to enjoy a special relationship with God. We possess imagination and the power of reflective choice. We are creative beings with the power of free choice because we were made in the likeness of the Person who created the whole of nature by a free choice. Many people use this power of choice in terrible ways. This does not mean human freedom is an illusion; rather that God takes our freedom so seriously that he allows our actions to produce their full consequences. Down through the ages we have been incurably religious. The urge to believe in and worship a higher power is present in virtually every human culture. The fact that we have a deep need to believe in and find God strongly suggests that God is real.   Ã‚  Ã‚  Ã‚  Ã‚  3.   Ã‚  Ã‚  Ã‚  Ã‚  A sentence stating the author’s purpose for writing. Evans is trying to convince the reader that humans were created with the need for God causing us to believe in and worship God hence God is real. 4.   Ã‚  Ã‚  Ã‚  Ã‚  A sentence identifying the author’s audience. Christian-minded believers of God who are seeking proof of God’s existence. 5. Your evaluation of what the author wrote (no more than three paragraphs). I found Evans’ arguments inadequate proof of the existence of God. Throughout the article the term â€Å"if Christianity is true†¦Ã¢â‚¬  is used repeatedly. The use of an â€Å"if† statement as the fulcrum of his philosophy places the entire philosophy on shaky ground. One would be forced to assume the Christian belief system is true, at least the most basic concepts, in order to believe in Evans’ philosophy. Additionally, Evans uses his arguments as particulars to jump to his final conclusion; a leap of faith, if you will.

Non thermal food preservation methods Essay

Food deteriorate in quality due to a wide range of chemical and enzymatic reactions, added to this the consumer demands faster production rate for high quality food with â€Å"fresh-like† characteristics and long shelf life, leading to the application of thermal processes for food preservation. However this thermal treatments cause undesirable effects on food flavor, color and nutritional attributes such as protein and vitamin destruction. These market conditions together with the disadvantages of the traditional food preservation technologies forced the food products manufacturers to seek for improvements in existing methods and the development of new preservation technologies. Called non-thermal food preservation methods, this new and emerging preservation techniques work by killing the microorganisms and inhibiting its enzymatic activity exerting a minimal impact on the nutritional and sensory properties of foods for an extended shelf life. Additionally non-thermal methods allow the processing of foods below temperatures traditionally used during thermal control processes, so flavors, vitamins and essential nutrients undergo minimal or no change. â€Å"They are also considered to be more energy efficient and to preserve better quality attributes than conventional thermally based processes. Non-thermal processes also meet industry needs by offering value-added products, new market opportunities and added safety margins (Morris et al., 2007)†. Foods can be non-thermally processed by high hydrostatic pressure, ultrasound, filtration, irradiation, hurdle technologies and electric methods such as pulsed electric fields, oscillating magnetic fields and high-voltage discharge. â€Å"Due to technological developments, high pressure processing and high electric field pulse processing have received increased attention during the last decade (Butz & Tauscher, 2002)  ¨. The main purpose of this assignment is to give a detailed review and approach to the non-thermal preservation technologies of pulsed electric field processing and high hydrostatic pressure processing by individually analyzing the objectives, equipment and process employed, effects in the food components and properties, and comparing and contrasting the advantages and disadvantages of each method to conclude which process can preserve in longer and in better shape the characteristics that define a â€Å"commercially† high quality product. PULSED ELECTRIC FIELD (PEF) Constituting a non-thermal treatment for food preservation which has a variety of uses in the field of food conservation, ranging from microorganism or enzyme inactivation and deceleration in liquid food to mass transfer process in plant materials (Wang et al., 2013). The application of PEF includes the implementation of short repeated high voltage pulses to form cell membranes and develops an alternative to the traditional pasteurization process in the food industry based on thermal processing (Janositz et al., 2011). Liquid, semi-liquid and solid food can undergo pulsed electric field processing. Objective Pulsed electric field processing use a strong defined system that rarely changes its foundations allowing it to keep the general objective of the non-thermal preservation technologies, inhibiting the enzymatic activation of that causes food decomposition using continuous intensive electrical pulses between electrodes to treat foods that consequently, inactivate microorganisms Equipment The food products that will be treated is a critical factor in design and equip with the adequate machinery the PEF system chamber, its hygienic design is also determining for the quality and safety of foods that will be treated and produced. The commonly used equipment for the pulsed electric field system consists of a high-voltage power source, and energy storage capacitor bank, a charging current limiting resistor, a switch to discharge energy from the capacitor across the food, and a treatment chamber (Ortega-Rivas, 2012). Treatment systems used in the pulsed electric field treatment can be classified as batch or continuous (Zhang et all., 2010). Batch or static system chamber consist in two parallel plates that provide the most uniform electric field area. Continuous have the same equipment for the high voltage pulse generator but also incorporate a pumping continuous system that allows the nonstop processing, necessary for the industrial application. Process Development The bank of capacitors is charged by a direct current power source from the amplified current main source. An electrical switch is used to discharge energy stored in the capacitor bank across the food held in the preservation/treatment chamber Mechanism of Action Pulsed electric field manages different types of voltages that cause different implications in the processed food, generating a short burst of high voltage to a food placed between two electrodes. When subjected to a higher electric voltage, a large flux of electric current flows through food surface acting a conductors because of the present of charge carriers like ions (Ortega-Rivas, 2012). Although the detailed mechanism that pulsed electric field uses to inactivate the enzymes and microorganism has not been fully clarified, two theories have been proposed: the dielectric breakdown theory and the electroporation theory (Zhang et all., 2010). In the dielectric breakdown mechanism a cell membrane with induced potential starts to compress from reversible pores to irreversible on the membrane, on the other hand the electroporation theory mechanism on a cell membrane makes a osmotic unbalance that swells and leads to a the membrane rupture. HIGH HYDROSTATIC PRESSURE (HHP) High hydrostatic pressure alters the equilibrium between protein-protein and protein-solvent interactions at different levels of pressure and time combinations causing minimal loss of vitamins and flavor compounds maintaining the sensory and nutritional quality attributes of food products. Known for its versatility in its applications, HHP provides new alternatives in food products such as cakes, jams, sauces and fruit juices making the further investigation of high hydrostatic pressure is necessary for seeking more advantages in other food processing products (Yang et all., 2012). Like pulsed electric field process, high hydrostatic pressure is an alternative to conventional thermal pasteurization for food preservation (Yang et all., 2012). Objective Using up to 600 MPa of high pressure, high hydrostatic pressure objective is to achieve microbial inactivation or to alter the food attributes in order to obtain consumer-desired qualities maintaining its natural freshness and extending its shelf life, causing minimal changes in the original characteristics of food by eliminating thermal degradation. Equipment Although the equipment used for high hydrostatic pressure is expensive and specialized, due to its popularity is available in a variety of types and quality. Every high hydrostatic pressure system consist of multiple components, its main constituents are the pressure vessel and its enclosure, the pressure generator system, the temperature control device and materials handling adaptation (Ortega-Rivas, 2012). The main factors food producers must consider when building the main components of an HHC system like pressure vessels are stress endurance, resistance and corrosion. High-pressure vessel is usually made of low-alloy steel (Bhat, 2011). Process Development Place the food package in a sterilized container and load it in the pressure chamber. Fill the pressure chamber with water and hold under pressure for the time required to pressurize the vessel. Depressurize the chamber and remove processed food. . After pressurization, the food is kept under high pressure for the required process time. Depressurization can be done faster. Mechanism of Action HHP removes air from the food packaging the products. During the pressurizing process the time required to pressurize the vessel is influenced by the compressibility and the nature of the food material but independent to the quantity of food placed in the pressure vessel (Ortega-Rivas, 2012). There are two types of pressurization systems, direct and indirect (Ortega-Rivas, 2012). The indirect pressurization system is pumped through a high-pressure intensifier into the pressure vessel, the intensifier is used to increase the pressure to desired levels. This system requires high-pressure tubing and appropriate fittings to convey the medium into the pressure vessel. In direct system, the pressure intensifier and the pressure vessel worked as a large single unit, so a piston is used to deliver the high pressure to the product. The limitations of this system are that it requires heavy duty seals that can withstand the repeated opening or closure and the need of a large number of seals between the pressure vessel and the piston. EFFECTS The wide field of application that both PEF and HHP have led to find in the literature many of experiments where the positives effects of this two process are observed in any kind of food products. Their most common effects are the inactivation of microorganisms and the enhance of biological compounds. Pulsed Electric Field Extension of shelf life produced by PEF has been reported. Antioxidant components such as anthocyanins, carotenoids, phenolic compounds and vitamin C are very sensitive to heat, effects of PEF is very low making it an excellent alternative to the thermal processes that lead to the loss of antioxidant and bioactive compounds (Bhat,2011). PEF effects in important parameters that determine the â€Å"commercial† quality of a final product have been demonstrated. Food parameters like drying, extraction and pression of solid texture can improve if using the suitable electrical load (Zhang et all., 2010). Enzyme inactivation after a PEF treatment is the secondary most important effect. High Hydrostatic Pressure By enabling the enzyme activation HHC prevents the rapidly and uniform propagation of microorganism throughout the food, making this the main effect in benefit of the product quality. APPLICATIONS As established at different points throughout the text, the applications of this two methods are used in all the food industry fields. Vegetable and meat product industries use these technologies to maintain fresh-like sensory qualities on its products. Sea food and juices and beverages focus more in increasing the water uptake and water holding properties (Klonowski et all.,2006). ADVANTAGES The main advantages of PEF and HHP in comparison with the thermal preservation process is the fact that their quality has been proved in products that globe all the types of food industries. Competition between the various types of processes makes companies optimize everyday technologies to deliver better quality products. DISADVANTAGES Due to the difficulty that represents obtaining the materials to build the machinery and the time that it takes, makes using PEF and HHP a privilege for those companies that can afford the high cost of manufacturing and maintenance. CONCLUSION HHP has a clear advantage over PEF due to the effects that water pressure have against inactivation of microorganisms, more effective than the electric pulses.

Irish and Chinese Experience in America Essay

The end of the civil war and the beginning of the industrial revolution started an increase of immigration into the United States because of a need for low paid workers. Immigrants from around the world fled to America taking valuable jobs away from American citizens. Immigrants who came to the United States sought out every job known to man. Anything from sweeping floors to craftsman was available to the immigrants. From 1880-1920 the population of the United States ascended from 50,155,783 to 105,710,620. 1 An increase of approximately 55 million people marked the start of the industrial revolution. The population of immigrants that came to the United States in the time period of 1880-1920 was about 15,000,000. 2 Fifteen million immigrants just in the period of forty years came to the United States and all in need of a job. Two groups in particular, the Irish and the Chinese. Both The irish and the chinese have many similarities and differences in their experience in america. Some of these are shared yet others are sole experiences of one group. The origins of Chinese migration started after Senator Thomas hart Benton of Missouri proclaimed movement towards Asia as America’s Manifest Destiny. Manifest destiny was the notion that the â€Å"white† race was destined to expand and rule the earth. Manifest destiny contributed as the primary reason for the largest acquisition of U. S. territory. As americans started to search for new lands in Asia, Asians Immigrants set there eyes on America. After the Annexation of california, Aaron H. Palmer proposed chinese laborers to be imported to build transcontinental railroad and also to cultivate the lands of california. Around 1849, Chinese migrants began arriving in America. The chinese migrated to the states for their own reasons which were getting away from the intense conflicts in china caused by british opium wars. Many migrants were also fleeing from the turmoil of peasant rebellions such as the Taiping Rebellion. Hard economical conditions were also a reason why chinese Migrants sleeked survival in America. Chinese immigrants migrated to america voluntarily as free labor. They wanted to earn money and go back to their native land. The Chinese were sojourners while the Irish were settlers. Most of the chinese migrants were married with wives in china and were mostly illiterate. While the Irish immigrated to America with Families, as settlers. While the chinese fled to America for a better future, the Irish migrated to America due to â€Å"starvation†. Irish, came in massive numbers due to a struggling economy in result of the potato famine. in the mid 1800s the Irish people suffered a severe impact when the Potato famine struck. It left many Irish poor beyond poverty. With the drastic loss of their main source of economy the Irish people were left no other choice then to come to America. The Irish described their migration to america in terms such as â€Å"exiles† or â€Å"homeless†. By Takaki’s accounts the Irish felt as if they were driven away from their homeland by â€Å"English Tyranny†. The english were seen as â€Å"savage tyrants† The Irish felt they had to go to America, and that it was a necessity for them. Another factor that contributed in the Irish migration was the idea of religious freedom. The Irish Immigrants were predominately catholic, this makes them the first major non-protestant group to enter the US, immediately causing Americans to perceive them as a threat. The chinese mostly came to america with the intent of going back to their families, WHile the Irish immigrated with their families with the intent of staying in America. The background of why both groups parallel in aspects of better future and hard economies, and resentment of british rule. Both the chinese and Irish were Transnational, living in both countries at the same time. Both groups sent letter homes, the chinese used family and villager networks to send letters home. Irish sent letters home describing the country that had no tyranny, with no intentions of going back. The chinese on the other hand ultimate goal was to save enough money to go back and build a better life for family back home. The flow direction of both groups were different. The chinese set out for the â€Å"Gold mountain† while the Irish fled english oppression to cross the atlantic to America. The chinese migrated far less in numbers compared to the Irish. The chinese migrated in hundreds of thousands while the Irish migrated in millions. Between 1815 and 1845 one million Irish came to America. By 1850, the Irish made up a quarter of the population in Boston, Massachusetts; New York City; Philadelphia, Pennsylvania; and Baltimore, Maryland. In addition, Irish populations were prevalent among American mining communities. By 1870, there were 63,000 chinese in the united states, 77 percent were living in california and elsewhere in the West,southwest, New England and the south. Both groups struggled effectively to get incorporated in the American Economy. The chinese worked hard in the californian mines, railroads and the fields. At first the Chinese were welcomed in california for their hard work and low wages. The chinese workers brought a lot profit to their employers. Due to their low wage, long hours, and no need to provided services such as lodging. The owners profited and preferred the chinese labor over americans. The fear of chinese gaining power to vote and chinese boys going to the same schools as the whites, several legislation passed to prevent them from doing so. In 1852, the california legislature passed a law that would tax foreign miners, who did not desire to become a citizen. Even if they wanted to chinese could not have become citizens, because of the 1790 Naturalization Law that reserved naturalized citizenship for â€Å"whites. † This Federal law limited naturalization to immigrants who were â€Å"free white persons† of â€Å"good moral character†. It left out American Indians, indentured servants, slaves, free blacks, and Asians. The chinese miners were taxed 3 dollars monthly, the sate profited 5 millions from the chinese by the 1870. The early economic incorporation of the Irish started from the lowest step of the ladder. Irish immigrants did not usually posses any real skilled forms of labor, So the work which they received was very menial. They worked the jobs that American citizens left behind, like cleaning and excavating, mining, construction, roads, canals,railroads. (Basically jobs that were surrounded by filth) The living and working conditions of both immigrants were extremely dangerous. Both groups worked on building Railroads. In 1865, fifty chinese workers were hired by the central pacific railroad to help lay tracks for the transcontinental line. The number of chinese workers increased to 12,000 within 2 years. The chinese labor were preferred due to low wages and no cost of board and lodging. The construction of the central pacific Railroad was a chinese achievement. The conditions were harsh and the work was long. The chinese were forced to work through the winter. Many died in the snow slides,in the winter of 1866. Shortly after the chinese went on strike demanding higher wages, and 8 hour work days. The demands were not met and the strikers were starved, and forced back to work.. alike there chinese counterparts, the irish workers built thousands of miles of rail lines such as the western and Atlantic railroad from Atlanta to Chattanooga and the Union pacific segment of the transcontinental railroad. Chinese were central to the construction of the central pacific railroad while the Irish were central to the construction of union pacific railroad. The Irish like the Chinese worked long hours. The Irish became Disposable workers. The Irish were assigned to jobs that were to dangerous for â€Å"american’s†. Irish workers had high accident rates. The Irish resist and sung songs for survival and morale. The Irish workers were treated poorly and treated as dogs. The Central Pacific railroad released thousands of chinese workers in 1869, after the completion of the railroad. These workers went to San francisco and were employed by boot, shoes,woolen,cigar and industries. Hundred of chinese also became tenant farmers and sharecroppers. With the passage of Chinese exclusion Act in 1882,the chinese demanded higher wages. Chinese exclusion Act was one of the most significant restrictions on free immigration in U. S. history, prohibiting all immigration of Chinese laborers. Chinese workers continued to be harassed and excluded the chinese from unions and industrial jobs, however the chinese fought against discrimination. Chinese six companies lobbied for civil rights of the chinese people. During the negations for the Burlingame Treaty the Six chinese companies successfully got the US Gov to recognize their right to immigrate to the US. The Chinese had many hurdles in the socio-economical spec term of the united states. In 1900 only 5% of chinese were women. External and cultural factors contributed to low number of female immigration to the US. Chinese tradition and culture restricts movement of women. Women were expected to take care of the house/in laws and was expected to stay at home. It was also expensive to immigrate with wife. It was also a hostage theory so the husband keeps sending money home and eventually returns home. Although women who did migrate were mostly working as prostitutes. By 1870, 61 % of chinese women were prostitutes. Although difficult, but some chinese were able to have families. The fire after the earthquake destroyed all records in San Francisco. People who were already here could now claim they were born here and become citizens. These led to paper son and daughters. Under fourteen amendment granting american citizenship to children of citizens born abroad. This paper method was an important way of entering the US in the 1906, and created a new wave of chinese immigrants to the United States. Gradually the chinese moved from sojourners to settlers. Chinese were building communites, and held bussiness such as laundary’s and shops in china town. The chinese also started to create organizations and communites. For example Tongs were an organization to control contrymen, and their objective was to protect and work with better relationshipes with the Americans. The orginazation also controled opium trade and prostitution. Fongs was also an organizatoin that was created by family and villagers to maintain clubhouses and temples. The fongs also serviced letters home and sent bodies home of the dead. Six chinese companies was also created for educational and health purposes, it also worked for equal rights. These organizatoins were a big part of the chinese community in America, they dictated, control and advocated for the chinese immigrants. The enviroment for The second generation was improved after world war II. Most chinese americans, expecially women were forced into their parents etnic enclave working for their familys or friends bussines. Early Irish Economic incorporation started at the bottom of dual labor market where they had to compete with nonwhite labor. The chinese were hard workers and were hired to when there was shortage of white workers. Crocker hired chinese workers and when whites complained he threaten to fire them. The chinese worker made lots of profits for their employers. Crocker also explained that the chinese workers are elevating whiter workers. While the chinese worked as labores ther whites can be in managment/supervisory postions. The Irish were at the same woorking pool as the chinese and blacks. Irish workers in the Shoe factory created a organization to fight low wages. Knights of Crispin demanded higher wages. An employer replaced his Irish workers with chinese and was praised by the press. The Irish were reffered to as unrully, and were imaged as race of savages. The Irish were also descriminated against and depicted as lacking puntuality. They were viewed the same as blacks. To gain higher status in the social and political areana the Irish used â€Å"white antagonism† to gain political and social status in the american society. The Irish also played the race card to their advantage. They used the white racism strategy in competting with the chinese in california and African Americans in the Northeast. After being depicted as the same level as African americans, The Irish started to point out there supremacy by poining out that they were white. From being outsiders they wanted to be insiders. They did so by claiming they were americans. They claimed they were americans by attacking blacks and posing as insiders. The Irish slowly started to asimilate from forigners to americans. The Democratic party welcomed the Irish, due to their high numbers, as voters, party members, but not office holders before the civil war. By the 1830’s the cathlic Irish stongly identified as democrats. The democratic party emphasised the â€Å"Irish whitness† to sommoth over divisions withing the party. They pointed out that the Irish were white, and thus deserved equal rights. More Irish Women started to migrage due to bad economical situtions. Women migrated to America in hopes of finding a job. Irish women entered domestic service because of room and board incentive because they were mostly single. Maids also got payied higher then a factory worker. Although they worked long hours,These domestic workers were expirencimg american cutlure first hand and was eaiser for them to adopt and settel in the american culture. The second generation of Irish had more economical mobility, were educated. 19 percent of Irish women born in America worked as servants,or laudress compared to 61 percent of the immigent generation. Most of female immigrants were illiterate, but there daughters were educated and took white collar jobes such as teachers, nurses, and secreteries. The second generation Irish had wider acceptance in the society. Political invorment also helped in adoption to the new country. Irish’s democratic invoment gave them a higher edge in the society. In NY, Boston, chicago, and SF Irish political machines fuctioned as Robin Hoods for the the Irish people. Irish amricans took white collar jobs and held important postions within the cities. The Irished used an ethnic strategy based on dominance, by using white supremacy in America. The Irish Dominated in the trade unions/ and held high skilled jobs which created â€Å"wages of Whiteness. † Irish workers continued comapinn to make american labor equal â€Å"white labor†. They started to monopolis better jobs, and excluded African Americans, chinese and japanese. The second generation made goals for their future while still remembered their culture through songs. Chinese and Irish Immirgrants struggled to make their place in the American society. Both Groups had to deal with Racism and discrimination. The settelment and economic socio- political adaption of both groups were drastically different from one another. The Irish were easily incorporated in the political areana because of their voting power. While the Chinese had a harder time because of the early legislation which did not grant chinese citizenships. I feel the Irish had some advantages over the Chinese migrants. Knowledge of the English language being one advantage and Experience in political organization which The Irish had mobilized labor movements against British, this made the Irish more politically savvy. Another factor why the Irish moved up the labor ladder was because they looked like americans and they used that as an advantaged to become the insiders. The chinese chose to live in their own nehiobrhoods which hindered them in adapting to amercan culture. If the chinese were more adaptive then They might of been more accepted by the society. ? ? ? ? ?

The Battle of Peleliu in World War II

The Battle of Peleliu was fought September 15 to November 27, 1944, during World War II (1939-1945). Part of the Allies island-hopping strategy, it was believed that Peleliu needed to be captured before operations could commence against either the Philippines or Formosa. While planners had originally believed that the operation would only require a few days, it ultimately took over two months to secure the island as its nearly 11,000 defenders retreated into a system of interconnected bunkers, strong points, and caves. The garrison exacted a heavy price on the attackers and the Allied effort quickly became a bloody, grinding affair. On November 27, 1944, after weeks of bitter fighting, Peleliu was declared secure. Background Having advanced across the Pacific after victories at Tarawa, Kwajalein, Saipan, Guam, and Tinian, Allied leaders reached a crossroads regarding future strategy. While General Douglas MacArthur favored advancing into the Philippines to make good his promise to liberate that country, Admiral Chester W. Nimitz preferred to capture Formosa and Okinawa, which could serve springboards for future operations against China and Japan. Flying to Pearl Harbor, President Franklin Roosevelt met with both commanders before ultimately electing to follow MacArthurs recommendations. As part of the advance to the Philippines, it was believed that Peleliu in the Palau Islands needed to be captured to secure the Allies right flank (Map). Fast Facts: Battle of Peleliu Conflict: World War II (1939-1945)Dates: September 15 to November 27, 1944Armies Commanders:AlliesMajor General William RupertusRear Admiral Jesse Oldendorf1st Marine Division (17,490 men), 81st Infantry Division (10,994 men)Japanese:Colonel Kunio Nakagawaapprox. 11,000 menCasualties:Allies: 2,336 killed and 8,450 wounded/missingJapanese: 10,695 killed and 202 captured The Allied Plan Responsibility for the invasion was given to Major General Roy S. Geigers III Amphibious Corps and Major General William Rupertuss 1st Marine Division was assigned to make the initial landings. Supported by naval gunfire from Rear Admiral Jesse Oldendorfs ships offshore, the Marines were to assault beaches on the southwest side of the island. Going ashore, the plan called for the 1st Marine Regiment to land to the north, the 5th Marine Regiment in the center, and the 7th Marine Regiment in the south. Hitting the beach, the 1st and 7th Marines would cover the flanks as the 5th Marines drove inland to capture Pelelius airfield. This done, the 1st Marines, led by Colonel Lewis Chesty Puller were to turn north and attack the islands highest point, Umurbrogol Mountain. In assessing the operation, Rupertus expected to secure the island in a matter of days. Colonel Lewis Chesty Puller, 1950. US Marine Corps A New Plan The defense of Peleliu was overseen by Colonel Kunio Nakagawa. Following a string of defeats, the Japanese began to reassess their approach to island defense. Rather than attempting to halt Allied landings on the beaches, they devised a new strategy which called for islands to be heavily fortified with strong points and bunkers. These were to be connected by caves and tunnels which would allow troops to be safely shifted with ease to meet each new threat. To support this system, troops would make limited counterattacks rather than the reckless banzai charges of the past. While efforts would be made to disrupt enemy landings, this new approach sought to bleed the Allies white once they were ashore. The key to Nakagawas defenses were over 500 caves in the Umurbrogol Mountain complex. Many of these were further fortified with steel doors and gun emplacements. At the north of the Allies intended invasion beach, the Japanese tunneled through a 30-foot high coral ridge and installed a variety of guns and bunkers. Known as The Point, the Allies had no knowledge of the ridges existence as it did not show on existing maps. In addition, the islands beaches were heavily mined and strewn with a variety of obstacles to hamper potential invaders. Unaware of the change in Japanese defensive tactics, Allied planning moved forward as normal and the invasion of Peleliu was dubbed Operation Stalemate II. A Chance to Reconsider To aid in operation, Admiral William Bull Halseys carriers commenced a series of raids in the Palaus and Philippines. These met little Japanese resistance led him to contact Nimitz on September 13, 1944, with several suggestions. First, he recommended that the attack on Peleliu be abandoned as unneeded and that the assigned troops be given to MacArthur for operations in the Philippines. He also stated that the invasion of the Philippines should begin immediately. While leaders in Washington, DC agreed to move up the landings in the Philippines, they elected to push forward with the Peleliu operation as Oldendorf had begun the pre-invasion bombardment on September 12 and troops were already arriving in the area. Going Ashore As Oldendorfs five battleships, four heavy cruisers, and four light cruisers pounded Peleliu, carrier aircraft also struck targets across the island. Expending a massive amount of ordnance, it was believed that the garrison was completely neutralized. This was far from the case as the new Japanese defense system survived nearly untouched. At 8:32 AM on September 15, the 1st Marine Division began their landings. The first wave of LVTs moves toward the invasion beaches, passing through the inshore bombardment line of LCI gunboats. Cruisers and battleships are bombarding from the distance. The landing area is almost totally hidden in dust and smoke. US Naval History and Heritage Command Coming under heavy fire from batteries at either end of the beach, the division lost many LVTs (Landing Vehicle Tracked) and DUKWs forcing large numbers of Marines to wade ashore. Pushing inland, only the 5th Marines made any substantial progress. Reaching the edge of the airfield, they succeeded in turning back a Japanese counterattack consisting of tanks and infantry (Map). A Bitter Grind The next day, the 5th Marines, enduring heavy artillery fire, charged across the airfield and secured it. Pressing on, they reached the eastern side of the island, cutting off the Japanese defenders to the south. Over the next several days, these troops were reduced by the 7th Marines. Near the beach, Pullers 1st Marines began attacks against The Point. In bitter fighting, Pullers men, led by Captain George Hunts company, succeeded in reducing the position. Despite this success, the 1st Marines endured nearly two days of counterattacks from Nakagawas men. Moving inland, the 1st Marines turned north and began engaging the Japanese in the hills around Umurbrogol. Sustaining serious losses, the Marines made slow progress through the maze of valleys and soon named the area Bloody Nose Ridge. As the Marines ground their way through the ridges, they were forced to endure nightly infiltration attacks by the Japanese. Having sustained 1,749 casualties, approximately 60% of the regiment, in several days fighting, the 1st Marines were withdrawn by Geiger and replaced with the 321st Regimental Combat Team from the US Armys 81st Infantry Division. The 321st RCT landed north of the mountain on September 23 and began operations. A U.S. Marine Corps Chance Vought F4U-1 Corsair aircraft attacks a Japanese bunker at the Umurbrogol mountain on Peleliu with napalm bombs. US Marine Corps Supported by the 5th and 7th Marines, they had a similar experience to Pullers men. On September 28, the 5th Marines took part in a short operation to capture Ngesebus Island, just north of Peleliu. Going ashore, they secured the island after a brief fight. Over the next few weeks, Allied troops continued to slowly battle their way through Umurbrogol. With the 5th and 7th Marines badly battered, Geiger withdrew them and replaced them with the 323rd RCT on October 15. With the 1st Marine Division fully removed from Peleliu, it was sent back to Pavuvu in the Russell Islands to recover. Bitter fighting in and around Umurbrogol continued for another month as the 81st Division troops struggled to expel the Japanese from the ridges and caves. On November 24, with American forces closing in, Nakagawa committed suicide. Three days later, the island was finally declared secure. Aftermath One of the costliest operations of the war in the Pacific, the Battle of Peleliu saw Allied forces sustain 2,336 killed and 8,450 wounded/missing. The 1,749 casualties sustained by Pullers 1st Marines nearly equaled the entire divisions losses for the earlier Battle of Guadalcanal. Japanese losses were 10,695 killed and 202 captured. Though a victory, the Battle of Peleliu was quickly overshadowed by the Allied landings on Leyte in the Philippines, which commenced on October 20, as well as the Allied triumph at the Battle of Leyte Gulf. The battle itself became a controversial topic as Allied forces took severe losses for an island that ultimately possessed little strategic value and was not used to support future operations. The new Japanese defensive approach was later used at Iwo Jima and Okinawa. In an interesting twist, a party of Japanese soldiers held out on Peleliu until 1947 when they had to be convinced by a Japanese admiral that the war was over.

Essay on Hume’s Reasons for Rejecting Miracles - 815 Words

Hume’s Reasons for Rejecting Miracles One of the main philosophers in the debate about miracles is David Hume. I will start this essay with a basic summary of Hume’s argument. Hume’s argument is not that miracles cannot happen, but that, given the amount of evidence that has established and confirmed a law of nature, there can never be sufficient evidence to prove that a law of nature has been violated. He believes that miracles have no rational background. Hume was an empiricist, in other words, he believed that all knowledge is based on evidence that we gain through our senses. He argues that if a miracle goes against a law of nature, then it represents a single piece of evidence that†¦show more content†¦Hume argues that a miracle is a breach of a law of nature. As I said earlier, he believes that the belief in miracles is not rational. He maintains that if you were a rational human being, you would not believe in miracles. Hume states that we have a uniform past evidence for laws of nature. For example, when people walk on water, they sink and when someone dies, they do not rise from the dead. However, Hume only deals with reports of miracles and doesn’t look at them from first hand experience. Hume furthers his argument by saying that the reports of witnesses are unreliable and untrustworthy. He makes the point that people who are claiming a miracle has happened should have a reputation to lose and absolutely nothing to gain. Hume advances on this argument to say that reports of miracles generally come from ignorant and barbarous people. He states that humans love the fantastic. People love the idea of something unlikely happening since wonder and excitement are enjoyable emotions. This argument seems to be weak since he only deals with word of mouth miracles whereas today there is much more scientific research into miracles. For example, the miracles at Lourdes. There have been 68 carefully checked claims that Natural Law has been broken and the church has declared them miracles.
