Matching Dell Case Analysis Essay

The PC industry can be analyzed using Porter’s Five Forces. The first force is threat or barriers of entry. Here, the threat is high and barriers are low. Although certain brands own the majority of the market, the costs to manufacture are extremely low, and the prices of these components are declining yearly at 25% to 30%. The capital required is relatively inexpensive, as well. Also, unbranded â€Å"white box† PC makers have become prevalent overseas; showing anyone who can make a PC could make sales. In Buying Power, consumers have great power. There are a high number of users but consumers have a wide variety of brands to choose from and have put much pressure on companies to make satisfactory products at good prices. Customers also have low switching costs. This force along with high demand was also partly responsible for the â€Å"vigorous price war† as many companies cut prices to match one another and satisfy consumers. Supplier power was also high. Intel and Microsoft ran near-monopolies in supplying microprocessors and operating systems, respectively. By 1998, 96% of all PC’s ran on â€Å"Wintel.† These two suppliers drew profits from all PC companies and minimized differentiation, as there were few substitutes and little options of switching to another supplier. The industry’s degree of rivalry reflected its fierce competition. As computers became more common, demand rose, prices decreased, and demand grew stronger, boosting competition between manufacturers. This rivalry is essentially what sparked Dell’s competitors to try to emulate their business model and attempt to gain a competitive advantage for the future. Lastly, the threat of substitutes was low but growing. Consumers were becoming reliant on PC’s as they became commodities but new technologies such as laptops, PDA’s, and smartphones among others were slowly emerging. Business Model Although Dell sold to a diverse range of customer segments, they generally targeted the â€Å"educated consumer,† people knowledgeable about computers. Dell targeted them and wanted to avoid the â€Å"inexperienced Transaction buyer.† Because Dell sold customized PC’s directly to the customer, they needed to know each computer’s specifications, thus making it difficult for inexperienced users to specify their needs. Dell’s close location to its suppliers served as a large advantage. Dell arranged for suppliers to  locate their production facilities close to Dell’s to maximize the efficiency of operations. This allowed Dell and suppliers to work closely with one another, integrating the organization and minimizing buffers. Dell’s unique production process is the part of the model that may deter most imitators. Dell had the advantage of handling fast and large orders and even having suppliers send shipments straight to customers in som e cases. Performance Dell’s success with the Direct Model led to rankings among the top of its competition in user ratings (Exhibit A), a ranking first in ratings for high-end PC’s, and allowed them to obtain the second and third spots for market share in the US and world, respectively. The financial statements that best measure Dell’s advantage are their inventory level ratios. Specifically, Dell’s days of inventory is significantly lower than competitors. Their low days of inventory ratio correlates to a very high return on invested capital and return on equity. Comparisons with competitors can be seen in the appendix (Exhibit B). Principal Issue Dell’s success in financial returns and rapid growth has caused rivals to try to emulate their Direct Model in attempt to gain a competitive advantage and similar success. What is difficult to emulate in Dell’s model and how can they keep itself in this position and leverage sustained growth for the future using this model? Alternatives Dell is the originator of the direct model and knows the formula for success. Dell’s integrated production process with suppliers on a global scale, sole focus on distributing directly to customers, ability to effectively serve a diverse customer base, and ability to provide high quality PC’s at relatively low prices, has put them in a strong position ahead of competitors. Dell knows their capabilities, their customers, and knows exactly to focus on direct distribution. IBM ranks alongside Dell in domestic and worldwide market share. As the first to recognize Dell’s threat of distribution, they took initiative immediately, responding with a joint operation with distributors and resellers called AAP. Many major distributors and resellers each invested tens of millions of dollars into  this program, which could result in powerful partnerships if successful. Compaq owned the largest market share in the industry for some time and are reliable to a number of segment s. They also responded with their own model, ODM, which is also in conjunction with distributors and resellers similar to IBM’s, and DirectPlus, selling directly to small and midsize companies. The company also recently acquired DEC, in which they would leverage their relationships to sell directly to DEC customers and accounts. HP created their own direct model with ESPP. Although their model was similar to IBM and Compaq’s involving distributors and resellers, they specifically aimed to please these partners. HP offered incentives and would make resellers and distributors a larger part of the process. In result, 59% of resellers reported they were more willing to promote HP products than IBM and Compaq. Gateway may have been Dell’s largest threat as the world’s second largest direct seller behind Dell. They even briefly surpassed Dell in sales in 1994 and their days of inventory was at 10 days, only 3 behind Dell’s 7 in 1998. Gateway served mostly pe rsonal users but began serving large corporate accounts with Gateway Major Accounts, Inc. in 1997. But in 1998, the company scaled this operation back as they could not afford to keep it up. Criteria Dell’s Direct Model had a competitive advantage rivals could not easily emulate through their relationship with large enterprise customers and their unique production process that involves a close relationship and location with suppliers. Recommendation Dell is in a strong competitive position against its rivals because of the criteria of advantages in their model. Dell’s production process and close location and collaboration with suppliers on a global scale is a standard that is very difficult to emulate. IBM, Compaq, and HP tried their own versions of direct distribution models but failed to produce anywhere near the same efficiency with financial returns as Dell (Exhibit B). Also, these companies attempted to branch into Dell’s lane while continuing retail sales, which showed it is difficult to focus on both methods and see the same success. Gateway was arguably their biggest threat but could not compete due to their inability to serve large enterprise customers similar  to Dell. Plan of Action Dell should continue to focus on relatively low cost, quality customized products through direct distribution. As technology and computers evolve with more computer alternatives, they should adapt to producing a more diverse product line but continue the same production and distribution process that has brought the firm so much success thus far.

The Mayans †Popol Vuh Summary

The Mayans – A Basic Summary on Popol Vuh and Xibalba Information on the Popol Vuh The Popol Vuh is one of the only remaining texts we have of ancient Mayan cultures. It is, for lack of a better word, their bible. In English its most direct translation is â€Å"Book of the Mat† but it can translate into its more meaningful name, â€Å"Book of the Community†. It encompasses a variety of stories and legends as well as a history of the mayan ancestors.Its most famous story is the creation myth of the Hero Twins. This myth explains how two abandoned twins ventured into the Mayan underworld called Xibalba and defeated the â€Å"bad† Gods and the arrogant Xibalbans people. They then ascended out of Xibalba to the sky where they became the sun and the moon. This book was an important source of cultural heritage to the Mayan people and the religions they practiced.It explains the importance of Maya as a divine place and culture, as well as introduces important fig ures such as the Maize God. After Bishop Diego de Landa’s eradication on Mayan literature, it is an extremely valuable source of information. Information on Xibalba Xibalba is to the Mayans what Hell is for us. It translates to something along the lines of, â€Å"the place of fear†. However, it has many important differences.For instance, instead of eternal damnation in one endless fiery pit (aka: Hell) there are seven chambers. Each chamber is a different challenge or nightmare that you have to face. The Mayans believe a person has five souls, one of which ventures into Xibalba. Depending on how evil you have been depends on how deep into Xibalba your soul goes. Again, the deeper you go, the worse it becomes. Xibalba has cultural significance because it develops the idea of key gods, religions and practices such as the Mayan ballgames.

Project management - Assignment Example First the objective of the projects are essentials to define, then the goals of project will be stated clearly and communicated to the team members that are associated with the project, then tasks will be defined, after describing the task, resources required for the project are essential to define, the last two steps of project scope involve budgeting and scheduling (Dyal 2008). The critical path method could help penny in assisting scheduling and decision making. Penny could create efficiency, reduce uncertainty, and improve productivity through the help of critical path method. This can help in assess the earliest time by which the each activity can be completed. Through full project Gantt chart penny can evaluate the scheduling progress on the basis of individual task and whole project (Schwable 2013) Resource costing method is best to save the extra cost of utilizing resources; the second method is standard costing that helps in cost control, and the third method is activity based costing that determine the cost each activity required (Lewis 1995) Before starting any project risk assessment is the first step, risk occurs due to lack of tools, information and qualified employees. All uncertainties will be assessed through risk assessment data sheet and risk assessment matrix. Then the action plan will be created after conducting SWOT analysis of project, insurance will be taken to transfer risk and constant monitoring will be conducted to ensure the risk free status of the project. There are multiple evaluation methods but no can be said best; project evaluation methods include qualitative method. The formative evaluation methods are essential to lead up the project that is missing in the case study. The goal based evaluation is missed in the project that is necessary for any project and give ideas to the team members and management that how should the work be done in order to attain the stated goals. This evaluation encounters the SMART targets

Health Care Delivery System As One of Vital Component of Public Welfar Essay

Health Care Delivery System As One of Vital Component of Public Welfare Schemes of the Government - Essay Example The needed reforms, therefore, require not only a comprehensive feedback of delivery system as a whole but a careful consideration to all the various pros and cons of the developing situations in the concerned areas of the public health care, has become the need of the hour.   The NHS1 facing multi-pronged problems needs to introduce some radical organizational changes to improve the health delivery systems. â€Å"Organizations must change because their environments change† (Bateman, 1990). They implement necessary changes in the organization to not only survive but also to improve their overall performance. But it is equally true that people tend to resist any kind of change and therefore it is important that changes are implemented in a manner that mitigates the resistance of the employees and instils confidence in them. A good leadership ensures effective communication with the employees with the shared vision of the new technology and methods of administration, thus promoting better understanding among the employees for easy changeover. The NHS, in one of its trust hospital, had tried to introduce the concept of multi-skilled working in the wards on a pilot basis. We would be analyzing the particular case study with reference to the implementation of the generic model of working. The trust hospital provides the full range of acute and midwifery services to roughly quarter of a million population. It has a strength of 2800 staff, 62% of who are part-time workers. 43% of the staff is female. The hospital is plagued with the increasingly low number of staff presence which is adversely affecting the quality of its health delivery system which resulted in a long waiting list and low quality of healthcare services. To cope up with the increasing ‘absenteeism’ and improve the quality of services which could reduce the waiting list while complying with the government initiatives, a concept of multi-skilled working was introduced. It involved about 250 people, in ward-based teams of support workers. On the pilot basis, this multi-skilled concept was launched with porters and domestic staff who were required to provide services in different areas like cleaning, transporting patients, moving types of equipment and serving food, on ‘as and when’ required basis.  Ã‚

Optional - Essay Example The transistors in the processing chips have continually reduced in size leading to the possibility of measuring them on basis of atomic scale. According to Hagar, 2011, the atomic scale perception of transistors allows QC to deploy quantum mechanics that are governed by wave and relativity laws. While digital computing uses bits, QC uses qubits. A bit represents 0 or 1. A qubit represents 0, 1 and any other superposition possible from the qubit values. This implies that while bits can only contain a particular value, qubits contain a vast amount of values. It is worth noting that QC is capable of undertaking multiple calculations while conventional computing would only partake to one calculation at a time. In addition, QC processes large volumes of data at the same time. It swiftly and accurately solves large relative mathematical problems such as the nondeterministic polynomial (NP) calculations. Chemistry uses the computer to model medicine molecules that are very sophisticated. In order to achieve this, complex calculations (Schrodinger Equation) guide in developing the model structure. The complexity of the medicine structure doubles with each electron added to the basic structure, which is a building block, such that there is a limit past which the conventional computing mechanism is overwhelmed. Currently, computers are only able to model molecular structure not exceeding 300 electrons. Quantum computing can solve SE equations with more than 30 electrons due to its ability to integrate, float and portray basic vast values as mere constitutes to infinite combinations. Systems rely on certain features of data encryption to safeguard sensitive information in banking or transaction activities. RSA is the unbreakable encryption system recognized today because it uses about 300 character integers to encode data. Any attempts to deceiver the encryption require large

Hazards of Aluminium Welding Fumes Research Paper

Hazards of Aluminium Welding Fumes - Research Paper Example The biggest problem is that the diseases do not develop immediately but appear after a few years of exposure. The impact of pollution at the workplace on productivity has been well investigated. Studies on the impact of pollution at work environment in productivity reveal a tendency of reduction in economic activity (Marrewijk, 2005). "Sick Building Syndrome" (SBS) and 'Building related illness' (BRI) gives rise to employee complaints such as headaches, dizziness, disorientation, fatigue, ear, eye and throat irritations. The world demand for high-speed ferries and LNG tanks is being met with an increase in Aluminium welding and casting production. This has introduced a new health hazard to the Aluminium welders and ways are being probed to protect the welders against the Aluminium fumes. In the U.K, the Control of Substances Hazardous to Health (COSHH) regulations stipulates that the occupational exposure limit for Aluminium fume should not exceed 5mgm exp 3 of air. Aluminium fumes during welding also generate quantities of ozone gas, which can cause nausea (Rabin, 1997) and unconsciousness. Welding is a process in which metal or other thermoplastic materials are joined together by the application of heat or pore sure or both. Electric welding was introduced in the 1940s. Aluminium welding has been in prominence since 1970. There are several types of welding like Arc welding and Manual metal arc is a common process where the workers are exposed to the fumes. Carbon arc, Cold welding, Electron beam welding, Flux core arc welding, Gas welding, Gas metal arc welding, Gas tungsten arc welding, Shielded metal arc welding, Plasma arc welding, Laser beam welding are the other welding processes where workers are exposed to metal fumes. The welding workers have a high exposure of metal fumes and the exposure depends on the place, confined space, workshop or open air.  

Strategic Choices for Coca Cola Company Research Paper

Strategic Choices for Coca Cola Company - Research Paper Example On the other hand, weaknesses of the company are negative publicity; health issues attached with the brand, some brands of the company are less popular, poor performance in North America and decline in cash from operating activities. Examination of the external environment demonstrates opportunities and treats of the company. Uncovered market, growing bottled water market, buy out competition and acquisition of the intense competition can be proves opportunities for the company. On the contrary, increasing health consciousness, increased competition from local and international players, legal issues, health ministries of various developing countries are imposing threats on the company (The Coca-Cola Company, 2011). In order to avail the maximum benefits of the strengths and opportunities, the company is advice to handle the threats and weaknesses very carefully. In this context, creation of competitive advantage is recommendable. When a firm has an edge over its competitors then it is said to have a competitive advantage. According Michael Porter, there are two types of competitive advantage viz cost advantage and differentiation strategy. Coca-cola achieved its competitive advantage by delivering same benefits as competitors but on lower cost i.e. cost leadership. However, both local and international competitors pull down its rates to the level of Coca-cola which ended its cost leadership. Then it came up with benefits that exceed those of competitors which are called differentiation strategy. This strategy worked in favor of the company as it positioned the company with distinctive taste in the market. It also added some snacks to its product line which again made its look different (Thinki ng made easy, 2009). The strategic choice of the company is based on the resource based view concept. This concept focuses on creation of competitive advantage by utilizing firm’s resources

The strong value of the Australian dollar and its impact on Assignment - 1

The strong value of the Australian dollar and its impact on Australia's exports about tourism - Assignment Example 102). The variations in the dollar usually come alongside different impacts on the general economy of the country. Depending on the prevailing level of elasticity, some firms are usually affected by the value of the dollar, while others benefit immensely from it (Carson, Richards & Tremblay 2005, p. 100; Gary 2006, p. 1). The export markets for various goods and services in Australia seem to be exceptional, but this is not always the case in the face of the changing value of the Australian dollar. According to the a recent survey that was done on the impact of the dollar, the value of the export markets fell down to ten places because of the appreciating value of the Australian dollar. This is according to the world ranking of export markets from Australia. It has been noted that the value of the Australian dollar has been on a steady upward since 2008 (Australian Capital Tourism Corporation 2004, p. 87). This is attributed to the prevailing economic boom as a result of the mining activities going in the country. In this respect, investigations conducted about the mining boom in other countries like China and countries in the East cannot be ignored (Nicole 2013, p.1; Robert 2013, p. 2). The increase in value of the Australian dollar has had a direct multiplier effect, meaning that other industries have equally felt it. These industries include the agricultural sector, service industry among many others. The impact of this rising value of the dollar has critically affected the tourism sector, which largely depends on people expenditure while visiting various places in the country (Tourism Research Australia. 2005, p.1 ). In general, it is a common observation that the elasticity of people’s expenditure in the process of touring various places in the country is large. For instance, foreigners income elasticity is directly related to the elasticity of

The benefits of open source software within the government and Essay

The benefits of open source software within the government and business sector - Essay Example The open-source software is developing rapidly and their functionalities are highly competitive and in fact much better than closed-source software. Above all, all of the above advantages come at a very minimal price, not even a fraction of what is spent on the closed-source software. But, having said that, there are several disadvantages that could pose a threat to the future of open-source software. So, when considering all the pros and cons of open-source technology, the Information System (IS) managers have a very hard task in their hands on deciding whether to go for this kind of software. There are several issues that a manager has to look forward, the primary criteria, of course, to be in contention as the leader in a competitive industry. So, this decision aids a lot in deciding the future of an organization. An IS manager has to take into account, the cost involved, security, efficiency, throughput, servicing, innovation and several other issues that lead to take this crucial decision. An analysis of the benefits attained by several government organizations and private organizations and the predicted growth of these org anizations is discussed here. This includes a detailed discussion of the features of open-source software, the role of a manager with regard to open-source software, the current trends and the future of organizations implementing open-source software. The analysis concludes with the best practices for managers in organizations implementing this technology.(Fanini, 2005) Open source, in general terms, is a method followed to allow global accessibility to the source of a product. It allows people from different regions, to access the code, innovate it and improve the functionality of the software. Open source became popular only after the spread of internet, with many people from several regions getting a common point of access. It is a distributed process when compared to the centralized closed-source development. The open source

Behavior of Gases Essay Example for Free

Behavior of Gases Essay Introduction: In this experiment, the problem trying to be solved is what gas laws are being used when the pressure, temperature, and volume are being measured. The three gas laws are Boyle’s Law, Charle’s Law, and Gay-Lussac’s Law. The Boyle’s Law is when volume and pressure are being compared. Pressure and volume are inversely proportional, because when pressure goes up, volume goes down. The Charle’s Law is when volume and temperature are compared. Volume and temperature are also inversely proportional as well. Lastly, Gay-Lussac’s Law is when pressure and temperature are compared. Pressure and temperature are directly proportional; therefore when pressure goes up, temperature also goes up. The formulas are as follows: Boyle’s Law: P2 P1 = P2 V2 Charle’s Law: V1/T1 = V2/T2 Gay-Lussac’s Law: P1/T1 = P2/T2 Hypothesis: If volume, temperature, and pressure are measured, they will follow the laws and fit under Boyle’s, Charle’s, or Gay-Lussac’s law. Expected Results: It should be expected that when volume and pressure are measured, pressure will go up and volume will go down. When volume and temperature are compared, volume will go up and temperature will go down. Lastly, when pressure andtemperature are measured, pressure will go up as temperature goes up. Experimental Procedure: Part I Connect a 20mL syringe to a LabQuest Select: File New Then, Mode: Change to Events with Entry Next, Enter Name as Volume Enter Units as mL Select OK Start at 10mL on the syringe and wait for the reading to Select Keep Keep at least 6 data points (any of your choice) Only pull the syringe out (making the mL readings higher each time) Stop the Data Collection and view the graph and points Record Part II Place an Erlenmeyer flask in a beaker big enough to fit the flask Connect a temperature apparatus to the Lab Quest and place probe in beaker Then connect the pressure tube to the Lab Quest in channel 2 and connect the other end of the tube with the rubber stopper to the Erlenmeyer flask Select: File New Then Mode: Change to Selected Events Exit In sensors menu, change units to Kelvin Tap graph X-axis: chose temperature Place faucet, room temperature water in the beaker Select Keep Place ice in the beaker Select Keep Place room temperature water in the beaker again and place on a hot plate Wait for the water to boil Place temperature probe and Erlenmeyer flask back in beaker Select Keep Record result from graph and chart Results: VOLUME (mL) PRESSURE 10 103. 27 12 87. 6 14 76. 14 16 67. 5 18 60. 96 20 55. 15 This data and chart is comparing volume and pressure. The graph represents the Boyle’s Law because as the pressure is going up the volume is going down. TYPE OF WATER TEMPERATURE (K) PRESSURE Normal 102. 8 295 Ice 98. 29 275. 4 Boiling 122. 31 357. 4 This data and chart is comparing temperature and pressure. The graph represents Gay-Lussac’s Law because as temperature goes up, pressure goes up as well. Discussion: This experiment went extremely smooth. The data was easy to collect as long as you kept the Lab Quest and tools stable to ensure for accurate readings for temperature, pressure, and volume. The graphs and data easily coincided correctly with the theories of the gas laws, as was shown accessibly once the graphs were made. Although the data coincided with the theories correctly, the temperature readings for freezing and boiling may have not been completely accurate because the temperatures of the water was not measured accurately for correct boiling and freezing temperatures, but recorded solely for the theories and to prove them. Overall, the experiment held up well and the hypothesis and theories were proven to be correct.

Warrington Environmental Pollution and Soil Health Risks

Warrington Environmental Pollution and Soil Health Risks Report on the environmental pollution and human health risks of soils in the former industrial area of Woolston, Warrington. 2.Introduction: As a result of rapid population growth followed by intense industrial activity and petrochemical development soils have suffered from contamination with substances of various origins (E.M.Garcia et al,2015).As a result of rapid industrialisation of cities such as Manchester, newly constructed canals were built all over the UK in order to increase trade as well as the exportation of goods. In the 1820s, a new canal was established along the river Mersey with the purpose of shortening the route of navigation through the meandering Mersey. 3.Study site. According to Warrington borough council, the New Cut Canal was opened in 1821. This 2km long canal was built in order to improve the Mersey and Irwell navigation by creating a shortcut for barges carrying goods between Liverpool and Manchester. Historical ordnance survey maps from 1907 show an adjacent chemical works, a large tannery, a slaughter house, a metal works and a gunpowder mill. Sustained industrial activity meant that the canal sediment was undoubtedly polluted by spillages from ships and industrial effluents (Hartley and Dickinson,2010). Following the establishment of the Manchester shipping canal the New Cut Canal began to decline until it was left derelict (Warrington borough council) and eventually the Canal was disconnected from the river and abandoned in 1978 (Hartley and Dickinson,2010). In that year, it was decided that the site was to be used for tipping under emergency procedures to deposit road construction rubble (Hartley and Dickinson ,2010). Following this history, it has been estimated that the site contains 9800 tonnes of polluted anoxic sediment. It is known that this polluted sediment contains elevated levels of TPHs (Total Petroleum Hydrocarbons), PAHs (Polycyclic Aromatic Hydrocarbons) followed by highly elevated concentrations of metals (Pb, Zn, Cu, Cr and Ni) and Arsenic (As) (Hartley and Dickinson,2010). 4.Methods: 4.1. Methods out in the field. 4.1.1 Soil samples To determine the degree of soil contamination at the site, soil samples were taken at various points along the New Cut Canal site. It was decided that a systematic sampling method would be used in order to record an adequate amount of data for the investigation. This sampling method had been chosen as it allowed one to determine the spatial pattern of contamination whilst limiting human errors (O1). Whilst at the site, transects had been established along the New Cut Canal site. Transects were established along a 700-metre stretch of the canal and each transect had been separated by 70 meters. In total there was 10 transects and along each transect,6 soil samples were taken approximately every 10 meters from the Northernmost point of the canal to the southernmost point closest to the river Mersey. Soil samples from each sampling point were taken just below the surface but in order to prevent large organic materials from interfering with the soil investigations later it was decided that each sample should be taken and the large organic matter (Roots etc.) should be removed. This was done using a measuring tape and a spade. The soil samples had been gathered in plastic bags. 4.2. Conductivity and resistivity values within the soil surrounding New Cut Canal. 4.2.1. Electrical Resistivity Imaging (ERI) using ERT (Electrical Resistivity Tomography) The ERI was used to show the potential mobility of trace and toxic metals within the soil by analysing conductivity data from the ERT and the EM-31. Conductivity measurements were taken using an ERT along a single transect measuring 35 metres between the New Cut Canal site and the river Mersey. The ERT takes conductivity measurements through a series of electrodes which are placed into the ground. Once these electrodes had been implanted and connected to each other via multi core cables a current was then injected into the ground through these electrodes and as the current passed through the soil resistivity measurements were taken. Changes in conductivity reflect variations in subsurface materials and higher conductivity readings are associated with higher metal concentrations in soil pore waters. Figure 1: Below is an image that shows the standard setup of ERT. In this investigation the electrodes were inserted into the ground at distances of 2 meters apart. The transect of electrodes covered an area between the New Cut Canal and the river Mersey and was carried out at an angle of 0 ° (North to South). Image from Terra Dat:   http://terradat.co.uk/survey-methods/resistivity-tomography/ 4.2.2. Geonics EM-31 Ground Conductivity meter ERT maps out the geological variations associated with changes in conductivity (Exploration instruments) as well as the EM-31. Unlike the ERT, the EM-31 gathers its readings by creating an electromagnetic field in the air using a coil wire which is separated from a receiver coil by 3.66 meters. The transmitted energy propagates into the subsurface where a second electromagnetic field is created due to the effect of soil moisture, conductive earth materials and other buried objects (Reynolds international,2011). The EM-31 is useful to this investigation as it can take conductivity measurements below 2 meters of the Earths surface. The data collected by both the EM-31 and the ERT could then be combined to determine changes in conductivity up to a depth of 3-4 meters. 4.3. Soil sample experiments in the lab 4.3.1. Determining total metal concentrations Following the onsite extraction of soils samples, they were then taken to the lab for further processing. Before any more investigations were conducted the soil samples were dried in an oven at 40 °C for 48 hours in order to remove all of the moisture.   Oven drying the sediment is crucial in this type of investigation as one can only compare the dry weight to the Soil Guideline Values (SGVs) (DEFRA, 2002). Once they had been dried, the soil samples were then processed further in order to analyse the total metal concentrations (Pb,Zn,Cr and As), bioavailability of those metals, organic matter content and soil pH. Soil samples were then sieved so that larger particles greater than 2mm in diameter were removed.   After the samples had been sieved, analysis of the bioavailability of metals was conducted. 10g of sieved sediment was then added to a conical where 50mL of 0.5mol acetic acid was added using a measuring cylinder. Once the acid was added the flask was sealed with Parafil m and placed onto an orbital shaker for 30 minutes. Whilst the samples were shaken, 2 30mL universal sample tubes were prepped (2 for every sample) and a Whatman no 1 filter paper was added to each of the tubes. After the cylinder samples had been shaken, they were left to stand for 10 minutes in order for the contents to settle (Beneficial to the investigation as it sped up the filtering process). Following 10 minutes, the supernatant liquid in the cylinder was then added into the universal sample tubes through the filter paper. Once one of the tubes was full the second one was then introduced to the filtering process. Eventually both universal tubes were sealed and then analysis of the metal concentrations was conducted by Atomic Absorption Spectroscopy (AAS). 4.3.2. Determining organic matter (OM) content Secondly, organic matter content needed to be measured, this was done using the loss on ignition method. This process began with the weighing of an empty porcelain crucible (W1). Soil was then added until it filled the crucible and was then weighed (W2). The air-dry weight was then determined by using the following calculation W2-W1. The minute that this was done the crucibles for each of the samples was then oven-dried at a temperature of 105 °C overnight and then placed in a desiccator the following morning. Afterwards, the samples were then measured again (W3). The crucibles were then placed into a muffle furnace and ignited at 450 °C for 8 hours and left to cool on a sand tray. After this, the crucibles were weighed again (W4). This was done to burn off any of the Organic Matter (OM) content. Muffled weight was then determined by using this calculation, W4-W1. The final method involved a simple calculation, shown below: OM content (% of dry sediment) = [oven dry weight (g) muffled weight (g) / oven dry weight (g)] x 100 4.3.3. Determining soil pH To begin with 10g of soil was added to a beaker using a spatula where it would then be mixed with 25mL of deionised water using a measuring cylinder. The beaker was then stirred well until all of the material had been suspended (To allow the contents to mix) shortly followed by a 15-minute period whereby the beaker was left to stand. Following the 15-minute period a pH strip was dipped into each of the samples. Using a pH reference card, the colours recorded on each of the pH papers was noted. 4.3.4. Determining Total (T) metal concentrations using XRF (X-Ray Fluorescence Spectroscopy) Finally, 10g of each sample was added into a small plastic bag and then shaken until all of the soil reached the bottom. The bag was then placed onto the test bed and then the XRF machine determined the % values of Pb, Zn, Cr and As. 5. Results 5.1.

Coming to Terms You roll the dice, you look at the cards, you pick a team then you pray. The whole idea is that you feel you have an edge over others, and that you are lucky. You think that you can beat the house, and in this new age of technology you can bring it all into the comfort of your home. This is how online gambling was created. In recent years online gambling has become more and more popular; a report released last year by a stock analyst said that online gambling revenues will nearly triple $3 billion by this year. To the many sports fan out there, how many times have you said, "Anyone could have predicted the outcome of that game." The truth is that gambling isn't easy. That is why it's called gambling, you are taking a calculated risk which you believe gives you a good chance of coming out on top. Often the people who decide that they want to start an online gambling account do not understand what they are getting into. There are two types of online gamblers. There are those who should be going to gamblers anonymous and those who think that online gambling is a quick fix to financial problems. To get started the user must give out an assortment of personal information including contact numbers and credit card numbers. For certain accounts they attract you with the promise free money. For example you may receive 10% free of your initial deposit. The entire idea of a deposit is to put a certain amount of money into an account and then you use this to gamble. After you have electronically signed away your credit cards and personal information you can start to have fun. Now you get to lose some money, maybe you will get lucky and break even.

Legionella pneumophila :: Essays Papers

Legionella pneumophila GRAPH Introduction: Legionella pneumophila are gram-negative rods. They are very difficult to culture because of their complex nutrient requirements, such as cysteine, high concentrations of iron, and the use of activated charcoal agar. They survive as intracellular pathogens of either protozoa or human macrophages. They are most often found in stagnant water reservoirs like air conditioning cooling towers, whirlpool spas, humidifiers, faucets and shower heads, and are infectious when inhaled. L. pneumophila was first identified and named after the American Legion convention of 1976, held in Philadelphia, PA. 182 people became infected, and 29 died (most of which were older men or cigarette smokers). Although this organism was named in the 70’s, retrospective studies showed cases since 1943. GRAPH Diseases: L. pneumophila has a very wide range of effects. Healthy individuals usually go through an asymptomatic seroconversion, while less healthy people may undergo Pontiac Fever or Legionnaires’ Disease (LD). In 1968, employees at the county health department in Pontiac, Michigan came down with a fever, but the responsible pathogen was not identified at the time. It was frozen and later diagnosed as L. pneumophila. Pontiac Fever, being milder than LD, generally does not need treatment. Infected individuals will show fever, muscle aches, and headaches, and usually recover between 2-5 days. Pontiac Fever will present symptoms anywhere from a couple of hours to a couple of days after exposure, while LD takes 2-10 days to incubate. LD patients have fever, chills and a cough, with x-rays showing pneumonia. This more severe form usually prevails in elderly, cigarette smokers, people with chronic lung disease, or those who are immunocompromised, such as cancer or AIDS patients. Virulence: Being a gram-negative bacterium, L. pneumophila has lipopolysaccharides (LPS) that act as endotoxin within a human host. The presence of a flagella is thought to mediate adherence to human lung cells, thereby causing infection, since flagella-less strains do not cause disease. Once attached to human cells, the organism is engulfed by a macrophage where is utilizes the internal environment to multiply.

Organizational Epistemology

Running Head: ORGANIZATIONAL EPISTEMOLOGY 1 Organizational Epistemology St. Rachel E. Ustanny University of Phoenix ORGANIZATIONAL EPISTEMOLOGY 2 There are different perspectives about the origin of knowledge, which have influenced the development of concepts such as a priori and a posteriori truth, epistemic regress, and sensual perception—Descartes (as cited in Cooper, 1999) argued that there are certain undeniable truths, which are obtained from our senses; Feldman (2003) noted that truth is obtained through one of or a combination of six means: perception, memory, testimony, introspection, reasoning, and rational insight; Feldman (2003) also reported that evidentialists believe that propositions must be substantiated; Bonjour (1978) articulated that truth is based on the existence of a priori knowledge, which is proven by engaging in epistemic regress; Schnapper (2009) noted that modern democracy calls for greater equality, including the recognition and acceptance of all perspectives as truth; and Webb (2007) reported that truth is that which is naturally experienced. In light of these varying perspectives about the origin of truth or knowledge, one cannot deny that the study of epistemology is very important to the development of new information, and socioeconomic progress. From an organizational perspective, epistemology provides a framework for critically analyzing and planning for the management and leadership of contemporary businesses—The change in the mode of production to that of knowledge work as reported by Drucker (1999) points to the need for contemporary organizational leaders to manage knowledge as a means of increasing productivity. This situation underscores the importance of deconstructing the origin of knowledge that workers produce on a daily basis. Epistemological Theories The multiple perspectives about the origin of knowledge have stimulated much criticism and skepticism about the validity and generalizability of epistemological theories. Nevertheless, this situation has continued to fuel the development of new theories, which have contributed to ORGANIZATIONAL EPISTEMOLOGY 3 the persistence of the epistemological debate over several centuries, and influenced its applicability to contemporary social problems. New theories about the origin of knowledge are still emerging as society is faced with unique challenges and alternate ways of learning and testing validity. Natural epistemology and the knowledge work theories will be examined as a means of garnering a better understanding of how modern society deals with and conceptualizes knowledge and uses it to improve social structures and systems. Four longstanding knowledge theories will also be discussed to facilitate an evaluation of the influence of past knowledge theories on contemporary problems—these four theories are: empiricism, rationalism, pragmatism, and relativism. Naturalized epistemology challenged the belief that one has to engage in epistemic regress to justify truth. It was proposed that truth is determined by scientific investigations and explanations (Feldman, 2003, p. 167). The tools, methods, and principles of science provide epistemologists with the means of testing and justifying knowledge, therefore machinery such as a lie detector enables contemporary investigators to examine individuals’ reactions (heartbeat, sweat production, and levels of anxiety) to determine if they are being truthful about a situation. This approach directly contradicts empiricism, which articulated that sensual perceptions enable human beings to determine truth. In this case, a lie detector would not be necessary to determine truth as the investigator would be able to use his or her senses to detect truth and untruth. While there is some merit in the empiricists’ approach, naturalized epistemology presented a replicable method that is less likely to fail due to human error. Knowledge work as argued by Drucker (1999) represents a shift in the nature of production from being purely manual as was contended by management theorists of the 20 th century (p. 79). This shift has increased the significance of epistemology in the workplace in that ORGANIZATIONAL EPISTEMOLOGY 4 managers are forced to contend with the sources and origin of knowledge that workers possess as a means of enhancing companies’ capacities to improve the productivity of the knowledge worker as was done by Taylor during the heyday of manual work. Knowledge work has challenged the society to come to terms with the importance of epistemology in everyday life and to find ways of optimizing it for development. Knowledge management is proposed by Wong and Aspinwall (2004) as a strategy for increasing the productivity of the knowledge worker, but despite this there are still challenges as it relates to those who possess tacit knowledge—the major concern for companies is the loss of productivity advances when the tacit knowledge worker leaves. It has therefore become increasingly important to find out how individuals gain knowledge in the first place, and then attempt to replicate those actions that are engaged in on a daily basis, which optimizes productivity, efficiency, and effectiveness. One cannot solve the epistemological problems of the contemporary workplace without reflecting on earlier conceptions about epistemology as articulated by empiricists, rationalists, pragmatists, and relativists. Empiricism argued that knowledge is derived from human sensual experiences and perceptions (Cooper, 1999, p. 117). This view is quite the opposite of rationalism, which contended that knowledge existed (a priori) before humans experienced it; therefore individuals derived knowledge out of necessity, which is later universalized if there are no exceptions (Cooper, 1999, p. 166). Pragmatism challenged empiricism and rationalism by arguing that the a posteriori and a priori conceptions of truth are false because knowledge is derived from practice, which results in the formulation of theories and provides opportunities for continuously evising and reformulating the theory to improve practice (Webb, 2007, p. 10691070). Relativism opened up the epistemological discourse to multiple perspectives of truth, so that knowledge is seen as socially constructed, experiential, dynamic, and variable—There is no ORGANIZATIONAL EPISTEMOLOGY 5 single truth that guides the solution to problems and knowledge is gained from all of the various means articulated by individuals, thus the empiricist is no more correct than the rationalist, nor the pragmatist, nor the natural epistemologist. There is merit in all perspectives and all must be considered when seeking justifications for the truth (Schnapper, 2009, p. 177). In light of the latter argument, management theorists must look to a wide range of epistemological perspectives to increase leaders’ understanding about knowledge work and how to increase its productivity. The tacit and explicit knowledge that workers possess is founded in first principles, as articulated by empiricists, and rationalists; as well as obtained from practice that the worker encounters as he or she carries out their duties—this (latter) pragmatic source indicates that each worker has the opportunity to discover truth in the execution of his or her duties. The fact that empiricism, rationalism, and pragmatism present valid perspectives about the sources of the knowledge worker’s knowledge indicates that there are multiple sources of truth, which contributes to the relativity of tacit knowledge work. Application of Knowledge to Organizational Leadership and Management The shift in the 21st century from manual to knowledge work has necessitated that management theorists and leaders critically examine and develop means for measuring and increasing productivity. This has contributed to the need for increased attention to different forms of knowledge, particularly distinguishing tacit and explicit knowledge to enhance management theorists’ abilities to capture the steps and processes involved in producing specific outputs (Manyika, 1996). Tacit knowledge is particularly difficult to capture, because it is the know-how that individual workers possess that they acquired as a result of their experience with particular tools, and their responses to unique challenges that stimulated them to innovate. ORGANIZATIONAL EPISTEMOLOGY 6 Making tacit knowledge more public within organizations is critical to the improvement of productivity and succession planning—According to Ambrosini and Bowman (2001) â€Å"tacit knowledge in particular may block adaptation to changes in the environment, hinder innovation and lead to the continuation of inferior work practices† (p. 812). It requires that organizational leaders examine epistemological theories to get a better understanding of the foundation of the know-how that individual knowledge workers possess. Pragmatism is the epistemological theory that facilitates the most likely explanation for the origin of tacit knowledge in organizations as according to Ambrosini and Bowman (2001) â€Å"tacit knowledge is context specific, is typically acquired on the job or in the situation where it is used† (p. 13); so pragmatists’ belief that theory emerges from practice and is applied back to it with the possibility of revising and reformulating it presents an explanation of tacit knowledge originating in experiences as they are encountered. Senge (2010) and Drucker (1999) have been my most influential theorists because of the fact that their propositions have helped to explain and present solutions to the challenges facing my organization. They argued that there are methods that can be used to help increase productivity of knowledge workers in an ever-changing world, which are aimed at measuring and improving the contribution of knowledge to organizational success. If companies fail to capture the tacit knowledge of workers, they are bound to face periods of slump when such workers leave the organization temporarily or permanently, as well as fail to make significant advances, because workers are not keeping abreast of new knowledge. The effective development of knowledge-based companies therefore depends on the implementation of strategies for standardizing and sharing such knowledge. In addition, there is a general need for the firm to control productivity so as to eliminate the possibility of being held at ransom by employees. ORGANIZATIONAL EPISTEMOLOGY 7 Converting companies to learning organizations was proposed by Senge (2010) as a means of increasing productivity and sharing knowledge. Five disciplines were proposed for solving the productivity challenges that face contemporary organizations: personal mastery, mental models, shared visions, team learning, and systems thinking. It is believed that the learning organization sought to create holistic changes in companies so that knowledge could be better managed, and all stakeholders could see that success was dependent on the relationship among the individual departments and the organization as a corporate entity (p. 2). It is important to note that in the learning organization, the tacit knowledge and skills that workers possess, is represented by personal mastery, and is shared with other workers and the organization through team learning. Knowledge management was proposed as a strategy for restoring power, over production, to the organization. Wong and Aspinwall (2001) noted that a knowledge management implementation framework should have five characteristics: â€Å"(1) a clear structure on how to conduct and implement knowledge management, (2) clear distinction among the types of knowledge to be managed, (3) highlight the necessary knowledge management processes or activities needed to manipulate knowledge, (4) include the factors that will affect performance, and (5) provide a balanced view between the role of technology and human beings in knowledge management† (p. 100). The knowledge management implementation framework serves as a strategy for reducing the autonomy of the knowledge worker, while increasing the control of the organization over productivity. Unlike the learning organization, knowledge management does not seek to create holistic change in the company, but isolates knowledge work as an aspect of production, and identifies the elements that are necessary for management to manipulate so as to increase productivity as was done in the time of Taylor (Drucker, 1999, p. 80). ORGANIZATIONAL EPISTEMOLOGY 8 The Future of Epistemology in Organizational Leadership Epistemology has an important role to play in the development of human services organizations. The concept of good governance that guides the effective management of such organizations articulates some of the productivity issues addressed by Drucker (1999). In the case of my organization, productivity is hindered by the fact that knowledge about specific critical aspects of work is possessed by the accountant who does not welcome succession planning, responds negatively to queries from the board of directors, works in isolation, and makes decisions for others and their departments unilaterally. This situation has contributed to inefficiency and ineffectiveness in a number of core areas of work, and as argued by Ambrosini and Bowman (2001) contributes to inferior work practices (p. 812). Good governance argues that successful management is characterized by accountability, transparency, participatory leadership, and responsiveness. This is reiterated by Drucker (1999) when he noted that productivity was curtailed by knowledge workers autonomy in deciding the task, and having unilateral control over the production process—The work done by the accountant is knowledge work and the fact that it is held only by him contributes to a situation where the organization is held at ransom. If there are opportunities for the improvement of the accounting function, this is hindered because of the lack of access by the organization to it, and the general lack of responsiveness to good governance practices. In the case of my accountant, deciding what to purchase without consultation, and refusing to answer questions posed by the board directors contributes to productivity problems. Drucker (1999) noted that overcoming this situation â€Å"requires changes in attitude not only on the part of the individual knowledge worker, but on the part of the whole organization† (p. 92). ORGANIZATIONAL EPISTEMOLOGY 9 The problems with the accountant articulated above can be solved by one of two or a combination of the following approaches. These recommendations were derived from weeks five and six discussion questions. These discussions enabled me to have a better understanding of the needs and challenges of my organization, and provided me with the opportunity to evaluate the company and make recommendations for its improvement. The following two recommendations represent the possible actions that I may undertake to increase organizational productivity: (1) reform the company to that of a learning organization, which takes a systems approach to productivity, thus the failure of accounts is not seen as an isolated element, but is the responsibility of all employees and departments, therefore all employees see it as critical to learn the tacit knowledge possessed by the accountant so that they are better poised to recommend changes. When all employees have a shared vision, greater pressure will be placed on the accountant to be accountable, transparent, and participatory in his leadership; and or (2) develop a knowledge management system to capture all of the job roles that are assigned to the accountant and the various steps that he undertakes to fulfill them—There will be need to integrate feedback components with the clinic nurse, statistical clerk, and clinic receptionist, before commodities can be purchased; and in order to successfully meet his reporting obligations he must answer specific questions about the financial status of the organization, which will automatically be shared with the board directors. Such a system could eliminate the lack of transparency, participation, and accountability that has curtailed efficiency and effectiveness. The implementation of a knowledge management system would also help the organization to be better operated as a learning organization, as the steps for each ta sk that is performed by the accountant would be accessible to leadership, which could be used to teach others by way of team learning strategies. ORGANIZATIONAL EPISTEMOLOGY 10 The future of management of human service organizations in the knowledge worker age is not totally distinct from traditional epistemology—it integrates critical concepts of the past to help solve new and emergent challenges. Empiricism, rationalism, pragmatism, and relativism are four of the longstanding epistemological concepts that guide management practitioners about the origin of tacit knowledge—On one hand know-how originates from the theoretical foundations of empiricism and rationalism as seen in the in the knowledge that individuals obtain through formal education that prepares them to fit into the workplace; and on the other hand it originates from the encountered experiences in the workplace. Both views are correct and hence when theorizing about the origin of knowledge in knowledge work, management theorists must be mindful that there are multiple valid perspectives.

Library Management System Essay

Our Library Management System is the application software that is developed to make a record of Book purchasing, book searching, book issuing and rent, book returned, catalogs, stock creation, all other fine books, popular and bestsellers and other Library related works. The scope of this software application is to generate the automatic process of manual handling of Library records and to handle the stock as well as book issues related information. The aim of the project is to make the manual handling of Library system into computerized system. The user can get the information regarding the important reviews and immediate search of records. Our Library Management System is a data processing system used to perform routine Library activities. In this system, the library management becomes more efficient and easier to handle with its reliable system components. Library system was developed in order to make computerized the borrowing and returning of books, return books, and add books, search books and special tools. With Library Management System, it can trace desired items  electronically without going through shelves. Library Management System supports other administrative tasks such as inventory and data processing. Our Library management system needs a flash drive that will be used as access of the student to borrow books. Every registered student who wants to borrow book is required to plug-in a flash drive during the registration. The file â€Å"Account.txt† will be created after the registration containing the registered borrower’s code and full name. The Administrator/Librarian has full access which is level 1 with this system while the staff cannot edit accounts and settings which is level 2; they are only in assign with the transaction. Library management system records every transaction in computerized system so that problem such as record file missing won’t happen. This system has records of the list of the users with access level; the users must have their User ID, Last Name, First Name, Middle Initial, Username, Password and Access Level. It has also records of a list of available books with the book number, description, Category and Stock Available. It keeps also the record of the borrowed books with the borrowed code, type of transaction, list of books, quantity and date and time in it. It has also the records of the borrowers with their borrower code, last name, first name, middle initial, and course in it. It has also the borrowers log history with the borrower code, type of transaction, and date and time. The information to be printed on the printer are the Registered Users, Book Record, Borrower per day, Penalty Slip and Borrowed and Returned Books. It also records the User Log History which contains the User ID, Full Name, Remark, and date and time. Our Library Management System has only three trials for log in. Our system also validates all inputs. Penalty for late in returning of books is 5 pesos per day and 50 pesos after 5 days. This system has a user-friendly interface to create an easy to understand environment and it uses consistent background and foreground color. All the forms in our system appear at the center of the screen. It can detect a flash drive automatically once it is connected and indicate a status. It performs adding, editing, deleting and searching of records. Our system is also reliable in computing penalty. It performs text to speech and SMS notification. It can also update the number of books and back-up files and  records.

“Panopticism” and “Our Secret” Essay

In Michael Foucault’s reading on â€Å"Panopticism† he breaks down the social/economical systems and explains that society’s mentality on the law system. He answers the â€Å"why question† in a way certain individuals act and think as they do. Many times his explanation is much branched off into a different level of thinking. In one paragraph in â€Å"Panopticism†, a disciplinary mechanism is described, which is considered the best way for one person to be punished, in the new knowledge and learning is gained by every individual. But in â€Å"Our Secret† by Susan Griffins she carefully constructs and describes history, particularly WWII through the lives of several different people. Such as David Bartholomae and Anthony Petrosky who had a difficult time grasping her concepts that says, â€Å"Griffin writes about the past on how we can know it, what its relation to the present, why we should care. In the way she writes, she is also making an argument about how we can know and understand the past.† Griffin strikes all of these aspects in her essay. What is most compelling about the essay is how she incorporated personal, family, and world history into a good story of narrative, without ever losing the factual evidence the story provides. In the paragraph on page 182 in Ways of Reading, Foucault explains how he feels a person should be disciplined and he looks at it from different angle to really understand. â€Å"This enclosed, segmented space, observed at every point, in which the person inserted a fixed place, in which the slightest movements are supervised, which all events are recorded in an uninterrupted work of writing links the center and periphery, in which the power is exercised without the division, according to a continuous hierarchical figure, that a person is constantly located, examined, and distributed among the living beings, sick, and the dead that constitutes a compact model of the disciplinary mechanism.† In the first sentence of the paragraph a description of how closely watched and evaluated the individuals are. All movement, all actions, everything would be analyzed. This is how he feels a disciplinary mechanism should be and is a key model to follow. Disciplining that way would make the individual a better person, which I believe; â€Å"exercising power without division† is an example. In her essay, Griffin incorporates stories of people from totally different backgrounds,  upbringings, including herself, all to describe the accounts of one time period. Each person history is somehow connected with the next, and each story contributes equally to the bigger picture of history. Griffin puts three types of histories in her text; personal, family, and world history. In her personal history, she describes her life, and childhood, which is intertwine with her family history. However, she not only talks about her histories, she talks about the histories of the other characters in the essay to bring across the world. One of the technique’s that Griffin uses to help the audience understand her concepts, is explaining two other story lines while telling her main story. The first on is description of a cell. Throughout the essay italicized sentences explaining the complex of a cell being placed randomly between passages. The description beings with a nucleus, and as the story progresses, so does the nucleus. She tells what happens to the nucleus, and how the inner cells work on developing a nucleus, which gave rise to many of other cells, that will eventually become an embryo. The other story line, were also italicize sentences, goes through the making and beginning of missiles. â€Å"The plague is met by order; its function is to sort out every possible confusion that is of the disease, which is transmitted when bodies are mixed together, that the evil is increased when fear and death overcome prohibitions.† Disease definitely confuses the society when two or more people come together and embrace there disease. Evil becomes very overwhelming when it cannot be controlled or prevented; with the help of the plague everything becomes more controlled. â€Å"It lays down for each individual his place, his body, his disease, and his death, his wellbeing, by means of an omnipresent and omniscient power that subdivides itself in a regular, uninterrupted way even to the ultimo determination of the individual, of what characterize him, of what belongs to him, of what happen to him.† The plague served as some sort of god to most of the people. It breaks everything down and describes â€Å"omnipresent and omniscient power.† Act as keeping an eye on the person that sort the test, show how an individual would react knowing that they are being watched regardless if they believe it or not. Just how they would adapt to their own surroundings. What are the most compelling aspects about Griffin essay is  the way she combine personal, family, and world, and etc. The reading is a novel, which helps the audience to understand the concepts with a clear and complete overall view of her world. Two other authors, Richard Rodriguez, and Ralph Ellison, who wrote about their life experience that’s better understood as an historical text that is view through the eyes of Griffin. Rodriguez explores his own educational history that called â€Å"The Achievement of Desire† and Ellison depicts his own journey and personal growth which is called â€Å"An Extravagance of Laughter†. Both their writing are seen through G riffin’s perspective, can be opened and examined from a different view, helping the people understand with more of a lucid view of history and what it is really about. â€Å"The mixture of the plague brings into play its power, which is on the analysis.† In this sentence it describes the strength that is considered power. Learning can only make you more intelligent and the more you know the broader you understand would be which in your mental state would make you stronger. â€Å"A whole literary fiction of the festival grew up around the plague: suspended laws, lifted prospect, individuals unmarked, abandoning their statutory identity and the figure which they had recognized, allowing some different truth to appear†. When the individuals were changing their personalities to fit into the containment, as I said earlier in the essay, their trying to adapt to their environment. But their also political dream of the plague, that got reverse. Not the collective festival, but strict divisions; not laws transgressed, but the penetration of regulation into even the smallest details of everyday life through the thoughts of complete hierarchy that assured the function of power; the masks were put on and off, but the assignment for each person was their â€Å"true† name, â€Å"true† place, â€Å"true† body, and â€Å"true disease†. This sentence talks about a different side of the plague, the â€Å"political side†. Instead of analyzing the people was forcing out the power to handle certain individual. This was the dream of many that instead of interaction and strict regulation of everything done. The separated story lines are placed in the story to explain the background and the past of everyone. The background and past are factors in developing the present and future, and the characters in the story and tendency to try  and forget their past, but not realizing that there are no escapes. Griffin illustrates the technique with Heinrich Himmler, a prominent Nazi figure during WWII. In every detail, she describes Himmler’s childhood, and the harsh ways of his father. She also trace his life, and evident there’s always a maker; base from his childhood that affect the decision made later on in his life. Griffins merely do this to help provide understanding on such behavior develops. The art of this technique being effective, however, that Griffin interconnects all three stories so the audience to understand other authors and texts. Richard Rodrigues is one author that already go through history, from an educational standpoint. He discusses his childhood, and how co ming from a working class family improved his learning process. He examines a bit about his family history and personal history as well. Rodriguez traces his family back to Mexico, their move to America, and the struggle of keep up with the America living lifestyle. He examine what was it like growing up in a Mexican American household. As he gets older he began to not like his background and roots at an early age. He was working on many ways to discard the Mexican persona and develop a stronger American one. Rodriguez hides himself behind an image of what he thinks he should be, but not who he really is. The aspect of his family and personal history into his world history. Both family and personal history with his family’s migrating to America. While the war was not in America, they had to endure racism and hardships in the comings to the United States. Another author that was looked at in the eyes of Griffin was Ralph Ellison’s â€Å"Extravagance of Laughter’s†. What was interesting about these two essays were not only that the histories, but a lot of the major themes were implied in the essays. Ellison has a vast personal history that surrounds by world history; however there is not too much evidence of his family history. His personal history begins in the south to the north in the early nineteenth century. He talks about accounts of racism that occur in both places, which fall into a larger picture in world history. He remembers racism happening throughout the country at the time. Ellison combines so much personal history and world that became so difficult to distinguish that his personal history effected world history. One of the themes that stayed incorporated throughout both essay was constant effort to hide the truth. Ellison had difficult time admitting and realizing his true place in society. He wore  Ã¢â‚¬Å"marks† to cover how he felt in certain situation that he was in. When Griffins talks about her family, she also speaks of a mask as well. She says, â€Å"I think of it now as a mask, not an animated mask that expresses the essence of the inner truth, but a mask that falls like dead weight over the human face, make face, making flesh a stationary object†. Both Ellison and Grif fin felt trapped in there mark, and it took there self-dignity in freeing themselves of the mask. It hit Ellison during a play and it hit Griffin after learning about her family history. All three authors are in a sense of historians. They write events that are in the past, which make it about history. The work they do are very good work, others use their writings as guideline of writing events in an historian context. The themes about finding the truth within one’s self are throughout working, and different types of histories are explored, making these text much more than just history. Ralph Ellison once said, â€Å"The way a person expresses both the agony of life and the possibility of conquering it through is the sheer toughness of the spirit. They fall short of tragedy only in that they provide no solution; offer no scapegoat but the self†. â€Å"The plague as a form at once real and imaginary, of disorder had as its medical correlative disciple. Behind the disciplinary mechanisms can be read the haunting memory of â€Å"contagious† of the plague can be used as effective way disorder†. The plague can be used as an effective way to discipline; it is how they would use it to effect even if it would be possible. Each author demonstrates the toughness of theirs spirit, and it is up to the person to decide whether history will repeat itself or not. They all did the part in providing solutions for history.

Now you can show everyone that electrical energy or electricity can be made from air and vinegar. After all, vinegar are freely available everywhere. Battery is a device that converts chemical energy directly to electrical energy.It consists of a number of voltaic cells; each voltaic cell consists of two  half-cellsconnected in series by a conductive electrolyte containing anions and cations. One half-cell includes electrolyte and the electrode to which  anions  (negatively charged ions) migrate, i. e. , the  anode  or negative electrode; the other half-cell includes electrolyte and the electrode to which  cations  (positively charged ions) migrate, i. e. , the cathode  or po sitive electrode. In the  redox  reaction that powers the battery, cations are reduced (electrons are added) at the cathode, while anions are oxidized (electrons are removed) at the anode.The electrodes do not touch each other but are electrically connected by the  electrolyte. Some cells use two half-cells with different electrolytes. A separator between half-cells allows ions to flow, but prevents mixing of the electrolytes. Vinegar is a solution of acetic acid and water. Acids donate H+ ions into a solution. The concentration of these ions is what determines whether a solution is a strong electrolyte (conductor) or a weak one. Since vinegar has a low concentration of acetic acid(about 5%) it only has a pH of only ~2. 4 and so is a weak acid.Review of Related Literature According to Doctor Sergey stated that vinegar have lots of electronic magnet cells that can because electricity will small megabytes. During the experimentation, the researchers found out that 4 pieces of calamodins are enough to light a certain bulb. It is also found out that a coin which is hot copper and copper wires are not the appropriate materials in making the experiment. Instead of the materials mentioned used the copper coin and alligator wire. The galvanized nail also matter in lightning the bulb. Use the 1. inches galvanized nail to balanced the flow of the current. Statement of the Problem The researchers aimed to answer the following: 1. How much amount of vinegar that can make the light emitting diode bulb light? 2. Can vinegar bean alternative battery? Significance of the Study This activity is done by the researcher with an important purpose. This activity is launched solely for the Fourth Year High school students of Surigao Education Center. Scope and Limitations This study focused only on commercial vinegar as an alternative source of energy.

On the second trial, they prepared 400ml but again it does not work. By the third trial, with the amount of 800ml of vinegar, it only produced a little amount of light on the led bulb. On their last trial, they tried to use more vinegar with the amount of 1000ml, and then it already made the led bulb produced great light. CHAPTER IV SUMMARY, FINDINGS, CONCLUSION AND RECOMENDATIONSIn this chapter the researchers will be giving the summary of th e findings of their study. The conclusions on the different problems that arose and to the recommendations on the kinds of improvement their readers can do in the near future. Summary With the use of vinegar it is proven effective when the copper wire and galvanized nail is inserted in it. Based on the observation of the researchers through experimentation it was proven that Vinegar can be an alternative battery and can be a good source of electricity and further justified based on the result of the study.Findings Based on the experiment conducted, the following were the findings of the study: 1. With the amount of 1000ml of vinegar, it can make the led bulb light with the use also of galvanized nail and copper wire 2. Vinegar contains small amounts of acetic acid that can make the led bulb light Conclusions Based on the findings the researchers have conducted, the researchers therefore conclude that vinegar can be an alternative battery and a good example of producing light.With th e galvanized nail and copper wire as the negative and positive the two components shouldn’t be attach with other with the flow of electricity there should only be one direction Recommendations The experiment is easy, you can spend lesser. This is recommended to all the people. By this study, a lot of people can get and get idea how to save money, and energy at home. Someday, vinegar will be a source of electricity. The researchers also recommend this to the following: * Students – this can help them to be their guide anf for them to try something new and develop their skills in investigatory. Teachers – to take this as an example to the students for them to encourage themselves to discover other kinds of alternative battery. The researchers recommend two title of further studies: 1. â€Å"Animal Urine as Alternative battery† 2. â€Å"Vinegar as a battery for Calculator† REFERENCES http://tag. wonderhowto. com/vinegar-battery/ http://hilaroad. com/c amp/projects/lemon/vinegar_battery. html http://www. youtube. com/watch? v=pq9NuvdLZaU&feature=gv http://www. termpaperwarehouse. com/search_results. php? query=vinegar+alternative+battery+ APPENDICES Vinegar as Alternative Battery Vinegar as Alternative Battery An Investigatory Project Presented to The Faculty of the High School Department Surigao Education Center Km. 2, Surigao City _______________________________________________ In Partial Fulfillment of the Requirements in Physics IV _______________________________________________ By: Edradan, Dhaniel Jefferson Yaun, Mary Allyssa Concon, Leonel Galos, Jancirfil Jimena, Rimar Villarojo, Kerr March 2013 APPROVAL SHEET Vinegar as Alternative BatteryPrepared & Submitted by MARY ALLYSSA YAUN, DHANIEL JEFFERSON EDRADAN, LEONEL CONCON, JANCIRFIL GALOS, RIMAR JIMENA, KERR VILLAROJO has been examined and is recommended for approval and acceptance for ORAL EXAMINATION.

This barrier also works as a  sacrificial anode, which means the coating will dissolve before the metal inside does, if the barrier itself becomes damaged. * Copper Wire – Copper  has been used in  electric wiring  since the invention of the  electromagnet  and the  telegraph  in the 1820s. The invention of the  telep hone  in 1876 created further demand for copper wire as an electrical conductor.

On the second trial, they prepared 400ml but again it does not work. By the third trial, with the amount of 800ml of vinegar, it only produced a little amount of light on the led bulb. On their last trial, they tried to use more vinegar with the amount of 1000ml, and then it already made the led bulb produced great light. CHAPTER IV SUMMARY, FINDINGS, CONCLUSION AND RECOMENDATIONSIn this chapter the researchers will be giving the summary of th e findings of their study. The conclusions on the different problems that arose and to the recommendations on the kinds of improvement their readers can do in the near future. Summary With the use of vinegar it is proven effective when the copper wire and galvanized nail is inserted in it. Based on the observation of the researchers through experimentation it was proven that Vinegar can be an alternative battery and can be a good source of electricity and further justified based on the result of the study.Findings Based on the experiment conducted, the following were the findings of the study: 1. With the amount of 1000ml of vinegar, it can make the led bulb light with the use also of galvanized nail and copper wire 2. Vinegar contains small amounts of acetic acid that can make the led bulb light Conclusions Based on the findings the researchers have conducted, the researchers therefore conclude that vinegar can be an alternative battery and a good example of producing light.With th e galvanized nail and copper wire as the negative and positive the two components shouldn’t be attach with other with the flow of electricity there should only be one direction Recommendations The experiment is easy, you can spend lesser. This is recommended to all the people. By this study, a lot of people can get and get idea how to save money, and energy at home. Someday, vinegar will be a source of electricity. The researchers also recommend this to the following: * Students – this can help them to be their guide anf for them to try something new and develop their skills in investigatory. Teachers – to take this as an example to the students for them to encourage themselves to discover other kinds of alternative battery. The researchers recommend two title of further studies: 1. â€Å"Animal Urine as Alternative battery† 2. â€Å"Vinegar as a battery for Calculator† REFERENCES http://tag. wonderhowto. com/vinegar-battery/ http://hilaroad. com/c amp/projects/lemon/vinegar_battery. html http://www. youtube. com/watch? v=pq9NuvdLZaU&feature=gv http://www. termpaperwarehouse. com/search_results. php? query=vinegar+alternative+battery+ APPENDICES
