The guiding aim and abiding concern of Corporate culture Essay

The guiding aim and abiding concern of Corporate culture - Essay Example Corporate culture has an influence on how the members of an organization conduct themselves in almost every aspect of their lives, in respect to their work, to create a good image. It is this behavior which comes to affect how employees interact with their fellow employees, all their clients (whether large or small), and those people who have an interest in the organization (whether they are shareholders or stakeholders). The corporate culture of an organization can also be defined as the values that contribute to the creation of an environment that is conducive both psychologically and socially and enable employees to work effectively without worrying about any conflict related to their work procedure. These values are based on the knowledge that has been gained in the history of the organization from its founding as well as the existing knowledge of the organization, which form the philosophies that hold the organization together. There are certain instances, however, where there m ay be many, different conflicting, cultures within an organization, and this usually occurs especially in the large organizations, because of the different paths that are pursued by the various management teams in achieving the goals that have been set for the organization. Corporate culture is an extremely complex phenomenon within an organization, and it affects those who are employed by it in their work lives in various ways. When one considers corporate culture, one will realize that it may have both positive and negative effects on the individuals involved. It is these effects, among others, which will be discussed in this paper. While, in most cases, it is the management of an organization or corporation which plays a crucial role in the creation of the corporate culture of the organizatio

Modern transparencies and unwanted-exposures Essay Example for Free

Modern transparencies and unwanted-exposures Essay Human beings have been constructing shelters to serve different purposes since the beginnings of civilization. How a building was constructed depended on three qualities set out by Vitruvius, the Roman architect in his treatise De Architectura †¢ Durability †¢ Utility †¢ Beauty Across the ages, one of these three criteria has been more important than the other. The precept of modern architecture is ‘form follows function’. The function of the building determines its structure. But built into this precept are many other modern and post-modern conceptions of notions such as privacy, publicity, sexuality, art, etc. Some of the key components of design are space, volume, mass, texture, shadow, light, materials, structure, etc. Each of these components has been given varied importance in the different times. Modernist architecture has been influenced heavily by the Austrian architect Adolf Loos who believed that ‘ornament is crime. ’ He said, The evolution of culture marches with the elimination of ornament from useful objects. He believed that the influence of culture on ornamentation would change with changing culture and therefore ornamentation itself would become obsolete. Adolf Loos said, â€Å"Does it follow that the house has nothing in common with art and is architecture not to be included in the arts? Only a very small part of architecture belongs to art: the tomb and the monument. Everything else that fulfils a function is to be excluded from the domain of art. † Ornamentation is tantamount to art, which Loos completely discredits by saying, â€Å"The house has to please everyone, contrary to the work of art which does not. The work is a private matter for the artist. The house is not. † He differentiates designing a house and depicting art in these words, â€Å"The work of art is brought into the world without there being a need for it. The house satisfies a requirement. The work of art is responsible to none; the house is responsible to everyone. The work of art wants to draw people out of their state of comfort. † Loos echoes the philosophy of Deleuze when he says, â€Å"The work of art shows people new directions and thinks of the future. The house thinks of the present. † According to Deleuze, art is supposed to provide signs reading which a person is supposed come out of the rote of daily quotidian life and move towards creativity. Entailed in this function of art is deep discomfort which is why a house is not supposed to perform the function of art. Entailed in the notion of a house is a feeling of comfort in the present. â€Å"The house has to please everyone, contrary to the work of art which does not. The work is a private matter for the artist. The house is not. † â€Å"The house has to serve comfort. The work of art is revolutionary; the house is conservative. † Adolf Loos strived to strip culture of ‘art’ and ‘ornament’ and bring to it pragmatism, functionality and rationalism. Each of these qualities is attributed to the male. They are in stark contrast to the Jugendstil artists from the Wagner school. According to Susan Henderson, â€Å"Loos maintained that strict gender distinctions were basic to the ordered logic of modern society, and he decried the ambiguous gender roles that had invaded art and culture. Jugendstil decadence lay in its unrealistic attitude towards the capitalist economy, its regressive fascination for a dying aristocratic tradition, and a benighted love of ornament that sapped the productive energies from Viennese culture. His call for cultural reclamation through a reinvigorated rhetoric set the stage for embedding a new masculinism in the language of early modernism and the reassertion of middle-class values after a generation of retreat from the productive enterprise. † There exists an in-built contradiction between notion of perfect space that the architect harbours and the real mess of daily life. In both cases the woman is positioned as hidden and within and is always object subject to the male gaze. The domestic space of the Josephine Baker is converted into an erotic space. Josephine is present ‘in absentia’. The architecture is incorporated into the body of Josephine Baker and the body is entrenched in the architecture. â€Å"This is a wide-ranging and multifaceted notion of circulation, which includes passages, traversals, transitions, transitory states erotic circulations. † (Bruno, 1992) Given this understanding of Loos’ psychology it is a little complicated to learn the aesthetics of the Josephine Baker villa in Paris. This villa stands in contrast to many other designs of Loos. Feres el-DahDah says, â€Å"It is an epistolary attempt to detail her image in ‘various points’ through a kind of writing that stretches a third skin between the body of the architect and that of the dancer. The house is an apparatus†¦through which one can somehow rub against, or trap, a dancer’s exoticized body. It is a building designed as a tactical enterprise, as the imaginary ‘prose’ of an amorous conquest in between whose lines (in between the stripes of its facades and the distribution of its rooms) one is to decode a longing to signify desire. In other words, this house corroborates someone’s yearning to touch the absent body of Josephine. † This ‘present absence’ of Josephine Baker is called by Adolf Loos, ‘modern distinction’. The intense longing for the absent object brings to life that objects giving it a surreal physical manifestation. The elevations of the Baker house support this Freudian argument. The empty spaces represent Loos’ phallocentric desired for the absent object. If the Josephine Baker house is a modern depiction of sexuality that uses large unwanted space as a representation of desire for the body of Josephine Baker, large space is also used to represent violence and inspire fear through the designs of panopticons. Panopticon is a prison designed by Jeremy Bentham, the eighteenth century English Philosopher. The function of a panoticon is to watch the prisons without the prisoners themselves being aware either of the observer or of the process of observation. Jeremy Bentham called it ‘sentiment of an invisible omniscience. ’ â€Å"the more constantly the persons to be inspected are under the eyes of the persons who should inspect them, the more perfectly will the purpose †¦ of the establishment have been attained. Ideal perfection, if that were the object, would require that each person should actually be in that predicament, during every instant of time. This being impossible, the next thing to be wished for is, that, at every instant, seeing reason to believe as much, and not being able to satisfy himself to the contrary, he should conceive himself to be so. This point, you will immediately see, is most completely secured by my brothers plan; and, I think, it will appear equally manifest, that it cannot be compassed by any other, or to speak more properly, that if it be compassed by any other, it can only be in proportion as such other may approach to this. † The fundamental structure of a panopticon consists of a circular building. The rooms of the prisoners are present in the circumference of the building. Iron grating is present on the inner circumference. But this grating is virtually invisible to the prisoner. Such a grating traps the prisoner between the feelings of freedom and imprisonment. The prisoner knows that there is a grating but he cannot see it. It places him a limbo between privacy and publicity. Violation of private space is violence nonetheless. The room of the inspector is at the centre of the building. The windows of the prisoners’ room ‘radiate’ through the centre of the inspector’s room such that the inspector has a direct view into the rooms of all the prisoners. The windows would be covered by blinds till the eye level of the prisoners. This function of a window is opposed to that perceived by Adolf Loos, â€Å"to let the light in; not to let the gaze pass through†. Of course, the context of the windows in both cases is very different. In a panopticon, light is allowed to pass through only to the extent that allows the inspector to see the inside of the cell. In a house, light must be let in to brighten the house and make it comfortable to the inhabitants.

Design of Condition Monitoring (CM) system of a Case Study

Design of Condition Monitoring (CM) system of a Case Study Term / Abbreviation Definition CBW Continuous Batch Washer CM Condition Monitoring DIN Deutsches Institut fur Normung (German Institute for Standardization) FFT Fast Fourier Transform FTIR Fourier Transform Infrared Spectroscopy IR Infra-Red OEM Original Equipment Manufacturer P-F Potential to Functional Failure PM Preventive Maintenance SGS Spring Grove Services TAN Total Acid Number TBN Total Base Number TWF Time Wave Form WDA Wear Debris Analysis Spring Grove Services has decided to embark on a Condition Monitoring approach for the maintenance of its most critical equipment. Criticality was established by carrying out a study on the main Utilities and Process systems/machinery. This report includes data and images from a Thermography study, carried out at SGS, as this type of CM has already commenced. The findings identified in this exercise have highlighted potential points of failure in the Novopac shrink-wrap lines. Lubrication and Vibration Analysis studies have yet to commence so will be considered from a look-ahead perspective. The areas of focus here are the 18 Stage CBW and the Kaeser air compressor respectively. There will be predictions and estimates made on possible findings and required follow-up actions. The report undertaken here confirms to the author the necessity of introducing CM for equipment that is central to the successful running of the SGS plant in Cork. Spring Grove Services is one of Irelands leading laundry rental service providers. SGS has four major processing sites in Ireland. The business model functions by supplying linen to customers on a rental basis. This is then collected after use and cleaned before re-supply. Clients are supplied from a pool stock i.e. linen is not specific to any one client. The plant in Cork, which is featured in our case study, processes on average 330,000kgs of linen per week which equates to approximately 660,000 individual pieces. Run hours are 85 per week. Its customers include Irelands biggest hotels and hospitals. There is a real time aspect to this industry in the sense that linen processed today may well be used in a hotel or hospital tonight. This same linen will probably have only arrived in the laundry this morning in a soiled state. Lengthy batch release times due to quality inspections do not feature as they would in the pharmaceutical and healthcare products industries. This does not mean that there are poor quality standards, it just means that there is a minimum of time to ascertain them. This super-lean model requires maximum availability of plant equipment so effective maintenance is paramount. The operating context is also a factor in the maintenance strategy: equipment with many moving parts operating in a hot, humid and/or dusty environment. Preventive and Corrective Maintenance has historically been accepted practice with SGS but Condition Monitoring is coming more to the forefront for the most critical equipment. SGS is part of the European wide Berendsen group. The first step in the Condition Monitoring journey was to identify the most critical equipment. This would naturally become the focus of CM. Appendices A and B illustrate how Utilities and Process systems interact at SGS. Appendix C explains in detail, using a Criticality Scoring Scheme (Wheelhouse, 2014), how the results in Figure 1 were attained. Figure 1: SGS Criticality Curve Figure 1 trends criticality for the various Utilities and Process systems/equipment in Spring Grove Services. From Figure 1, we can deduce that the most critical assets are the CBWs, the Plastic Wrappers and the air Compressor. On further analysing the failure modes associated with this equipment, we can decide on where the exact focus of CM will be: 18 Stage CBW: This machine is the work horse of the Wash House as it alone processes 50% of the linen. Its most critical piece of equipment is the drive motor/gearbox assembly. We will apply Lubrication Analysis to the gearbox. Plastic Wrappers: These pieces of equipment form the final stage of the laundering process. Failure here creates a severe bottleneck. We will apply Thermographic Analysis to the electrical control panels. Air Compressor: If the compressor stops, production stops as there is no redundancy available. We will apply Vibration Analysis to the bearings as they are overdue replacement according to Original Equipment Manufacturer specification. 3.1 Equipment Description Figure 2: Lenze GST Geared Motor (Source: Geared Motor Spares) Figure 2 shows the type of geared motor used to drive the 18 Stage CBW (Geared Motor Spares). Lenze GST Helical Gearbox Power: 18.5kW Speed: 331rpm Torque: 518Nm Ratio: 4.457:1 Product Code: GST09-2MVBR180C12 Oil manufacture/type: Shell Omala S4 GX 320 Quantity of oil: 4.8 litres 3.2 Testing Overview The main purpose of carrying out lubrication analysis on this gearbox is to determine its health. The health of the lubricating oil itself is of secondary importance to SGS as it is a relatively inexpensive and easy task to replace. Because of these considerations our findings on Wear Debris Analysis (particle count) and Content Analysis will be used to make an overall estimation of system health. Where possible analysis performed through In-line or On-line methods is often preferable. However in this instance, neither of these options is possible so Off-line sampling will have to suffice. Off-line analysis does however provide increased scope for evaluating a greater variety of debris (Pruftechnik, 2002). Figure 3: GST gearbox lubrication service points (Source: Geared Motor Spares)    Figure 3 illustrates the various lubrication service points on a Lenze GST type gearbox (Geared Motor Spares). To take an oil sample, we will employ the following procedure: Ensure that the gearbox/oil is at normal operating temperature. It is not safe to take a sample while the gearbox is in operation due to the proximity of hazardous moving parts. We will therefore instead stop the machine and take a sample as soon as the drive motor is safely isolated. 100ml will be extracted using a Vampire Pump and entering the gearbox through the Breathing/oil filler plug as displayed in Figure 3. This method of extraction is known as the Drop Tube Sampling Method. Figure 4: Drop Tube Sampling Method (Source: Zidoune) Figure 4 shows a Vampire Pump extracting oil using the Drop Tube Sampling Method (Zidoune). Precautions when sampling: Record time, date and operating conditions. Oil must be at operating temperature. Ensure clean bottles and new tubing are used. Take oil from middle of gearbox i.e. not too close to the bottom. A turbulent zone is best. Samples should be sent for laboratory testing without delay. Poor sampling = poor results = poor decisions (Zidoune, 2013). 3.3 Test Findings Visual Inspection This can be performed by onsite staff prior to laboratory analysis and observations will be aimed at the following: Foaming an indication of contamination, passage through restricted openings or excessive churning. Emulsion water has entered the gearbox. Darkening oxidation has occurred or oil has been exposed to excessive heat. Laboratory Analysis On receiving laboratory results, we will consider the following factors in estimating the health of the gearbox: FTIR This provides information about oil chemistry and particulates. It can also determine if there has been a decrease in desirable content such as corrosion inhibitors. Viscosity This can tell us much about the lubricants condition. It can also give us an insight into system health when considered alongside factors such as detergency and dilution. Metal Concentration This is a key health indicator. The presence of certain metals can point towards the defect location e.g. Lead and Tin detected in large amounts indicates wear of a white metal bearing. TAN/TBN Acid number determines amount of oxidation present in the oil. Base number is an indication of the capacity to neutralise acids. Fault Level Settings Gearbox or oil manufacturers should be consulted, however setting useful alarm limits can be subjective as there are many variables in the operating context that it is not possible to account for in their specifications. Alarm limits are best set by initially estimating, based on specifications, and then gathering data over a period of time to tune the initial estimates. This will help reduce both false triggers and potential failures. As there are three CBWs in the wash house with identical drive systems, there is a likelihood that a gearbox will be fully overhauled in the not too distant future. We could use this opportunity to get data from perfectly healthy system i.e. a reconditioned gearbox with new oil. ISO Coding Sample Standard Cleanliness Target for an Industrial Gearbox: ISO 17/15/12 (Angeles, 2003) Table 2 Table 2 contains hypotethical data that we would expect to see in an oil sample taken from a healty gearbox. Using ISO 4406 methods with this data would give us a code of 17/15/12. 3.4 Conclusion Trending It is imperative that a trend is developed from the successive analysis exercises. This will result in a graph curve which displays system health and allow for a timely maintenance intervention when required. Recommended sampling frequency Care must be taken here as 100ml test amounts will render the gearbox empty of oil after 48 samples. Topping up the gearbox after each sample is not recommended as introducing new oil dilutes the existing content and thus distorts WDA data. Current oil replacement interval is every 4 years. Initial sampling frequency will be every 6 months with the gearbox oil level topped up every 12 months. Quick wins Spurlock (n.d.) states that one of the most common points of ingress for contamination in a gearbox is the OEM breather. It is recommended that an aftermarket breather be used instead. 4.1 Equipment Description Figure 5: Novopac ANL 090 Wrapper (Source: Bidspotter) Figure 6: Novopac BM2009 Heat Shrinking Oven (Source: Bidspotter) Figures 5 and 6 show examples of the Novopac Wrapper and Heat Shrinking Oven used in SGS (Bidspotter). Novopac ANL 090 Wrapper and BM2009 Heat Shrinking Oven (both function as a combined unit). Power: 41kW. Output per min.: 8/16 packs. 4.2 Testing Overview It was decided that SGS would purchase a thermographic camera and have one of the maintenance technicians trained in its operation. The supervisor consulted with the technician immediately after the study was completed and again when the full report was completed. 4.3 Test Findings There were two areas that were cause for concern: the three phase power supply connection and the DIN rail mounted contactors. Three Phase Power Supply Connection Figure 7: IR image Figure 8: Standard image Table 3 Figures 7 and 8 show both an IR and a standard image of the three phase connection block. Table 3 lists the data recorded by the camera in this instance. Action taken: The hot spot found in Figure 7 was found to be a loose connection on the DIN rail connection block. Tightening the same connector resolved the issue. DIN Rail Mounted Contactors Figure 9: IR image Figure 10: Standard image Table 4 Figures 9 and 10 show both an IR and a standard image of the DIN rail mounted contactors. Table 4 lists the data recorded by the camera in this instance. Action taken: Figure 9 indicates that there is a temperature build up between the contactors. On consulting previous reports, it was found that the temperature readings were similar during the last thermographic study. At this point the contactors were actually located closer together. A recommendation was made at that time to space out the contactors to allow for extra cooling. However this has made no difference but since there has not been deterioration in the state of the contactors, SGS has decided not to take any further action at present. 4.4 Conclusion The overall conclusion is that, beyond the tightening of the loose connection, there is no serious action required regarding repairs. However SGS has realised that there are shortcomings in the testing procedures which are mainly down to the technician not being trained to the proper standard. Listed below are the observations and recommendations relating to this viewpoint: The approach being applied is a Qualitative one which is sufficient for identifying the presence of a fault. It is also effective as a comparative technique. A Qualitative approach measures the Blackbody Apparent Temperature. Neither reflected/transmitted radiation nor emissivity has been accounted for. To get a true temperature reading, a Quantitative approach would be required. This will not only identify the presence of a fault but also its severity. Reflected/transmitted radiation is accounted for by entering the ambient temperature in the IR Camera. This can be done using pre-measured or estimated values. A correct entry here would provide the Blackbody temperature. Emissivity can be accounted for by entering a pre-measured or library values. A correct entry here, combined with accounting for the reflected/transmitted radiation, would provide the actual temperature. 5.1 Equipment Description Figure 11: Kaeser CS76 (Source: Synairgies) Figure 11 shows the type of Kaeser air compressor used in SGS (Synairgies). Kaeser CS76. Type: Rotary screw wet. Power: 45kW. Motor speed: 3000rpm. Mains frequency: 50Hz. Pressure: 7.5bar. Year of manufacture: 2004. Total running hours: 53563. On-load running hours: 42789. Recommended frequency for bearings replacement: 35000 hours this activity has yet to be completed. 5.2 Testing Overview The most likely cause of a screw compressor to fail is its bearings (KCF Technologies, n.d.). Accelerometer Locations For our Kaeser machine, we will apply vibration monitoring at the radial bearing positions of both the motor and compressor. This area will get a particular focus because OEM specifications suggest the bearings should have already been replaced. SGS is hoping that vibration analysis will give a true indicator of bearing condition and thus inform of the optimum time for bearing change-out. Figure 12: Sensor locations (Source: KCF Technologies) Figure 12 shows typical mounting positions, in yellow, for sensors to measure vibration at motor and compressor radial bearings (KCF Technologies). Mounting technique Accelerometers will be stud mounted to help ensure the most accurate readings. Accelerometer selection and equipment set-up Frequencies associated with bearings usually occur in the 1 to 5 kHz range. For this application an accelerometer with 25 kHz natural frequency is required. Sampling frequency (fs) = 2.56 x 5000 = 12800 Hz. For Fast Fourier Transform Spectrum Analysis, to achieve a frequency resolution of less than 1Hz: df = fs/N à ¢Ã¢â‚¬ °Ã‚ ¤ 1 N is the number of data points. N = 2^14 = 16,384 fs/N = 0.78125 Crest Factor or Kurtosis on Time Wave Form Acceleration signal can be employed to assist with diagnosis. Velocity and Acceleration will be the main focus for FFT. 5.3 Test Findings TWF and FFT For fault diagnosis, we will refer to TWF and FFT graphs. Figure 13: TWF and FFT (Source: Sinha) Figure 13 displays vibration acceleration measurement for a ball bearing in the initial fault stage (Sinha). Vibration Alarm and Fault level examples Table 5 (Source: Zargar) Table 5 lists vibration limits for a similar size and specification to the Kaeser CS76 (Zargar). 5.4 Conclusion A successful vibration monitoring program can be most difficult to attain for screw compressors. This is because of the high frequencies associated with the bearings, gearbox, male and female rotors. The associated noise pollution of the compressor can cause additional monitoring problems (Zargar, 2013). For the Kaeser compressor, there is a risk that bearing wear is present because of the hours run by the machine. However we cannot draw a firm conclusion on this until we develop a trend based on several sets of analysis data. The ultimate goal is to capture the point at which the bearings begin to deteriorate and from there successfully monitor the P-F interval. This will enable a well-judged maintenance intervention. CM want to have: If sufficient finance was available, a great option would be to invest in an Online monitoring system and have data fed back to a central PC. The software package could then issue periodic reports as well as alarm condition notifications. It is clear, I believe, from this report that embarking on a Conditioning Monitoring programme would bring great benefit to SGS. As well as the immediate gains to be made on the above equipment, the following should also result as pleasant side effects: An awareness will have developed among the key stakeholders of the advantages of CM over other types of maintenance. Technical staff will have an opportunity to upskill in either carrying out CM activities such as the Thermography study or be involved in interpreting results from Lubrication and Vibration analysis. There will be a willingness to roll out CM to other pieces of equipment. Thermography is an obvious contender as the equipment is already purchased. Downtime in the Wash House should be reduced as potential failures in the 18 Stage CBW drive gearbox will be identified before descending into functional failures. Again, as soon as this benefit is realised, this approach should carry across to other equipment. The criticality study which underpins the CM strategy will help focus technical resources on the most important equipment to the business. The expected success of the programme in the Cork plant should result in adoption of CM across the other sites in Ireland as there has always been close cooperation in terms of maintenance practices and parts sourcing. There will be an opportunity for the maintenance department to come to the forefront of the company when reporting the expected good news stories to emerge from adopting this new maintenance approach. Continuous improvement will organically develop from CM and bring kudos to the maintenance team. The general non-contact nature of CM will enhance safe working practices. The non-intrusive nature of CM will result in less equipment stoppages and reduced maintenance induced failures. The maintenance team will be encouraged to work more closely with equipment and components suppliers. This will help better inform future selection of machinery. It should be the beginning of a new maintenance culture across the organisation. Angeles, R. (2003). Tables on Oil Analysis. [Online].

Birth Control Through the Times Essay -- Contraceptives, Birth Control

The idea of men and women having control of their familial future is nothing new. In fact, the use of contraception dates back to ancient Egyptian times. Despite the controversy that often surrounds the use of birth control, history shows that the need for pregnancy prevention existed even before most modern religions were established. This paper will cover the colorful history of what we now know as birth control, through the centuries and up to modern times. Hopefully, this can give the audience a good idea about how necessary this concept is, and to look at the idea of controlling your destiny with objectivity. Beginning in ancient times, people saw a need to control the amount of children that they may have. One civilization in particular, the ancient Egyptians, had novel approaches to birth control. Drawings found from the time, around 3000 B.C., depicted men wearing condom like devices. This civilization also had what is called a pessary, which is an object or mixture that is inserted into the vagina to block or kill sperm. Some of their mixtures may have included pebbles, crocodile dung, or even rock salt. The Egyptians also used sea sponges drenched in lemon juice; much like a woman today might use a sponge with a spermicidal. The Egyptians weren’t the only ancient civilization to utilize birth control methods; the ancient Greeks used a method of post coital birth control. This method was employed when the couple was done with sexual intercourse, and the woman was to squat and apply pressure to the abdomen to rid the vagina of semen. Yet another approach from within the same ti me period was that of Aristotle, who recommended that women â€Å"anoint that part of the womb in which the seed falls† with olive oil, cedar oil, or f... ...e or not to have children. This is a pattern that will no doubt persist in the future as long as laws allow it. With that said, hopefully some insight can be gained by learning about the history of birth control, and perhaps it can demystify this taboo that no one wants to talk about.

Ernest Hemingway Essay -- essays research papers

Ernest Hemingway was born on July 21, 1899 in a small community of Oak Park, Illinois. He was the second child out of six, with four sisters and one brother. The area Ernest grew up in was a very conservative area of Illinois and was raised with values of strong religion, hard work, physical fitness and self-determination. His household was a very strict one that didn’t allow any enjoyment on Sundays and disobedience was strictly punished. Ernest’s father taught him good morals and values that he if he followed that he would be good in life. His father also taught him to hunt and fish around the Lake Michigan area and to love nature. The family would spend their summers in the wilderness and their winters back near Chicago. For the rest of his life Hemingway remained an avid fisherman and never lived far form a fishing hole. The outdoors is where he created a lot of his work, and a place where he got a lot of his inspiration from. Hemingway went to school in the Oak Park public school system where he wrote for the High School paper. Hemingway graduated high school in 1917 and then he took a job as a reporter for the Kansas City Star. This was against his parent’s wishes of him going to college to become a professional. While Hemingway worked for the Star, he learned to elaborate more and polished his writing ability positively. He found out after awhile that writing for the newspaper wasn’t for him. He had tried to join the military after he had graduated from high school b...

Determinism and Free will Essay -- Philosophy Philosophical Essays

Determinism and Free will Suppose that every event or action has a sufficient cause, which brings that event about. Today, in our scientific age, this sounds like a reasonable assumption. After all, can you imagine someone seriously claiming that when it rains, or when a plane crashes, or when a business succeeds, there might be no cause for it? Surely, human behavior is caused. It doesn't just happen for no reason at all. The types of human behavior for which people are held morally accountable are usually said to be caused by the people who engaged in that behavior. People typically cause their own behavior by making choices; thus, this type of behavior might be thought to be caused by your own choice-makings. This freedom to make your own choices is free will. Determinism, a philosophical doctrine against freedom, is the theory stating that all events, physical and mental (including moral choices), are completely determined by previously existing causes that preclude free will. This theory denies the element of chance or contingency, as well as the reality of human freedom, holding that the "will" is not free but is determined by biological, environmental, social, or mystical imperatives. Since every event in our lives is determined by outside causes, then we are just some sort of robots. Freedom, on the other hand, is rooted behind the idea that we do have control over the choices we make, thus having free will, a requirement for being morally accountable for an...

English Language Learners at the Elementary Level Essay

During English learning sessions, learners who are not native English speakers or those who English is not their first language have been identified to have anxiety and a sense of being alienated in to a language they do not belong or understand, have found themselves in crisis when trying to pass information using a language they are not certain and much concerns have been raised over the self-typifying era of being uncertain in whatever they do. All these have been recognized as themes of the philosophy of existentialism. These themes have significant implications for practicing education practice in learning English language. This philosophical paper has a number of purposes. First, it seeks to clarify the five philosophies of education. Their definition and explanation of what they are and what they are not forms one of the aims for this research paper. The position of existentialism is explained in relation to those other philosophies. This philosophy is clarified explicitly and the most common deviations from what the philosophy is are highlighted. Too often, existentialism is by mistake assumed to refer to an individual’s atomistic view. Such individual is assumed or imagined to be in a capacity to exercise his or her absolute right of freedom. The clarification of this issue is made by three philosophers namely Kierkegaard, Nietzsche and Heidegger. Secondly, this philosophical paper aims at applying the philosophies of education in the context of learners of English language at elementary level. It presents an outline of an existential framework which is structures mainly around and about the notion of English language learner who Is specifically at elementary level who is depicted as being in relation, embedded to a certain notion and language culture, a learner who is totally alienated in a world or environment where English is the popular and desirable language and is determined to make meaning out of his or her current status of being meaningless. These attributes have one on one implication for the ideal ‘English speaking and writers’. These impacted people are those who have been taught English as their mother tongue language or have learned the language sufficiently such that it is almost impossible to identify those who were born and taught English as the language of the earth and those who just perfected their English skills at a later stage of their lives, either at primary or secondary level of education. Again, these attributes have impact on the so called ‘English man’ which is more often than not articulated as the aim of introducing English lessons in most of the worlds education programmes. Attaining utmost understanding of English and being in a position to communicate as perfect as ‘Irish man’ using English according to this framework means being authentic, critical and having attained a personal identity as an English language speaker. A third aim of this paper is make argument on how English language learners at elementary level may usefully and successfully apply the philosophy of existentialism in creating identities in English language classes and practice sessions. By applying the philosophy, learners stand a chance of self discovery through active participation and while they enjoy the freedom of choosing what they feel is best for them. The existentialism philosophy is in support of the ideas of pedagogical approaches in education. English learning requires such an approach and by this means, learners are able to effectively examine the approaches by use of crises and anxiety generated from existentialism philosophy. English language syllabus for elementary level as well as other programmes and policies that support English learning stand a chance of being critiqued using the philosophy. Research Questions This research paper shall try to answer few questions that arise whenever the subject of educational philosophy is put on table. First, what is the definition of existentialism as a philosophy in education? What does existentialism entail? What cannot be referred when defining existentialism and what is antagonistic to existentialism? Which of the educational philosophies can be applied in the process of learning English as language? Of all the applicable philosophies, which one is the best to adopt while teaching or learning English language?
