Employee resourcing - Essay Example Recruitment is the process of attracting a pool of applicants to fill current and future vacancies. A vacancy may result if an employee quits the job, is promoted, or new vacancies due to restructuring or improvements. After recruitment, the selection process begins whereby the right candidates are selected from the pool of applicants to fill the vacancies using various methods and techniques. The recruitment and selection process is important as it ensures quality and productivity, reduces labor turnover, as well as saving time and money needed for future recruitment practices (eHow, 2011). The paper will discuss the various recruitment and selection methods as well as develop a recruitment strategy for an organization. Organizations have become very particular about recruiting candidates for employment due to recession and high unemployment in UK. Recruiting is therefore very important in ensuring success of the organization and is an overall HR planning strategy. Recruitment is the process of attracting potential candidates to fill in vacant positions or for future placements. Mathis and Jackson (2010) acknowledge the need for organizations to carry out strategic recruiting so as to achieve organizational effectiveness. This entails determining the industry where to recruit qualified individuals, being aware of competitors’ strategies so as to identify the key to success, forming relationships with the sources of prospective employees, and promoting the company brand (p.178). Due to many issues concerned with employment laws, the recruiters should also be trained on the laws. For recruitment to be successful it should be an ongoing process and the management should decide the method to use based on costs and effectiveness. There are various recruitment methods such as; promotion, job rotation, former staffs, employee referrals, job centers,

What is the role of sonication during protein extraction Assignment

What is the role of sonication during protein extraction - Assignment Example Sonication plays a role in the process of protein extraction. A sonicator, which is an ultrasonic device, helps grind samples that contain the protein. This initiates the sonication process. Sound waves that contain high intensity produced in the process of sonication disrupt cells. This in turn facilitates the extraction of protein from the cells and tissues after breaking open (Emily, 2012, 5). A sonicator consists of two tips of different sizes. The variation in tips creates diversity in the grounding of samples regardless of their amount. Large samples are ground in tubes with wide mouths while smaller samples are ground in eppendorfs. According to the Journal of Theoretical Biology, the process of sonication produces different efficiency levels (Journal of Theoretical Biology, 2012, 76) There is more resistance to the process by cell walls as compared to cell membrane. To tackle this, the samples with cell walls become flash frozen. This facilitates sonication. In conclusion, the process of sonication becomes essential in protein extraction. It is a mechanical method. Complemented by other chemical procedure of protein extraction, sonication allows the cells to break open and protein extracted from them by use of high intensity

The Statistical indicators of DSL Subscribers Essay Example for Free

The Statistical indicators of DSL Subscribers Essay The repeating sentences: 2nd repeat: United States and Japan are losing export market shares and new actors are emerging such as Hungary, Finland and Czech Republic. Page 3. Change to Due to the fact that United States and Japan are losing a number of their export market shares, their Balassa index has subsequently decreased. In addition to this, Hungary, Finland, and Czech Republic, as new actors, has much potential with regard to their Balassa index. The RCA index presents information about a country’s comparative advantage in ICT exports of goods and table below makes obvious each country’s gain or lost comparative advantage in ICT export through changes of RCA. RCA equivalent 1 indicates an identical export structure; RCA above 1 indicates relative specialization, while RCA below 1 means a countrys de-specialization. Page 4: kindly delete this paragraph because the term â€Å"RCA† has already been explained and there is no need to introduce this again. Price is consistently a very important issue. Nowadays the supply side hat vast influence of price and it is one of the largest barriers to purchase of broadband service. The Statistical Indicators: In this section, descriptive statistics will be used to describe the characteristics of the data set regarding the DSL subscribers. Different statistical measures will be used and will be introduced in the following sections. Measures of Central Tendency: The value for the mean of the data set is equal to 3251010.03. This means that on the average, there are about 3251010.03 DSL subscribers in the OECD countries. The Median of DSL Subscribers is equal to 1136709.50. This is the middle of the data set which means that half of the OECD countries have DSL subscribers above 1136709.50 and the other half has less than 1136709.50 DSL subscribers. The computed value for the Mode of DSL Subscribers is equal to 60024.00. This means that a number of OECD countries has this much DSL subscribers, more specifically the countries of . Measures of Variability: The standard deviation describes the degree of spread in the data set. If the data lies close to the mean, then the standard deviation is small. The standard deviation for the number of DSL Subscribers is 4645295.15. It shows the amount of deviation from the mean (3251010.03). Apparently, the value of the standard deviation is far from the mean and this shows that the data set has a high degree of spread. The largest number of DSL Subscribers is 19031154.00, which is in the United States, and the smallest number of DSL Subscribers is 60024.00, which is in Luxembourg. Computing for the range, which is the difference between the largest and the smallest value, the result is 18971130.00. This also indicates the degree of spread in the data set since the largest value and the smallest value is far from each other as indicated by the big difference in their range. The value for the Skewness of the data set is 2.08. It means that the distribution of the number of DSL Subscribers is referred to an asymmetric tail extending out to the right or skewed to the right. Correlation between the number of DSL Subscribers and the Monthly Charge In order to find the correlation between the Monthly Charge and the number of DSL Subscribers, the Pearson’s correlation is used.   The results show that the Pearson’s coefficient has a value of -0.355 for these two variables. It shows that the relation between Monthly Charge and the number of DSL Subscribers is negative and it implies inverse association. P-value is equal to 0.027. The P-value is smaller than 5%, which means that there is a correlation between the two factors but with the coefficient less than 0.5, the correlation is said to be weak. The graph below shows the negative relation between the number of DSL subscribers and the Monthly charge. It means that countries with lower Monthly charge have more DSL subscribers. The distribution of countries in the graph is expansive and far from the correlation line. It reaffirms the previous conclusion that the correlation is not strong. Correlation between the number of DSL Subscribers and the Speed of Connection The Pearsons correlation is used to find a correlation between the number of DSL Subscribers and the Speed of Connection. The Pearson’s coefficient is equal to 0.5. With the said value, it can be concluded that there is a positive correlation between the variables Speed of connection and the number DSL Subscribers and it implies direct association. The computed P-value is equal 0.002. Because this value is between 0 and 0.5, it means that there is a direct relation between the two factors where countries with higher connection speed have more DSL subscribers. The graph below shows that there is direct relationship between the number of DSL subscribers and the Speed of Connection. It shows that in countries where the Speed of connection is higher, there are more DSL Subscribers. Correlation between the number of DSL Subscribers and the Monthly Charge and Speed of Connection The possible value for Regression’s coefficient is between 0 and 1. If it is 0, then there is no correlation between factors of regression. If it is equal to 1, then the correlation is perfect. Also, the result of the analysis regression’s coefficient near 1 shows strong correlation. The regression coefficient for measuring the correlation between two variables will be computed. These variables are the Monthly Charge and Speed of Connection as the independent variables and the dependent variable which is the DSL subscribers. The result shows that the regression coefficient value is equal to 0.574. It shows that there is a correlation between Monthly Charge and Speed of Connection with the number of DSL subscribers and this relation is . There is another Index that will be used which is the R2. It is between 0% and 100%. It shows the percentage of change in the independent variables (Monthly charge and Speed of Connection) in relation to the change in dependent variable (number of DSL subscribers). It determines the influence that the independent variables (Charge and Speed) have over the change in the number of DSL Subscribers. The R2 for the current variables is 0.330. It means that 33% of change in the number of DSL Subscribers can be attributed to Monthly Charge and Speed of Connection and rest is from other variables. In addition to this, it is necessary to compute for the Beta Index. This Index determines the influence of each of the two independent variables, Monthly Charge and Speed of Connection. The value of Beta for Monthly charge is negative, which is -0.286. The value of Beta for Speed of Connection is 0.457. Upon a comparison of the value of Beta for the two independent variables, it could be said that the influence of Speed on the number of DSL Subscribers is more significant than the influence of Monthly Charge on the number of DSL Subscribers. In addition, the negative Beta Index of Monthly charge on DSL Subscribers means that as the Monthly Charge decreases, the number of DSL Subscribers increases. The graph below shows this regression. Correlation between number of DSL Subscribers and the Monthly Charge in Middle East The rate of Broadband penetration in Iran and Middle East is insignificant. The table below shows the Broadband penetration in Middle East. -Correlation between the number of Broadband Subscribers and ICT Export in Middle East The data on hand shows that the Pearson’s coefficient value of the number of Broadband Subscribers and ICT Export is equal to .939. It shows that the correlation between number of Broadband subscribers and ICT export is very strong. P-value is equal to 0.000, which means that there is a correlation between Broadband subscribers and ICT export. The Regression’s Coefficient is 0.993 which means that the correlation of the two variables is strong since the value of 0.993 is close to 1. In addition to this, the R2 value is equal to 0.98. It means 98% of the change in the number of Broadband Subscribers in Middle East is related to ICT Export. The graph below shows this regression.    The result can be considered for countries with available data. Due to the fact that there are not many countries with Broadband subscribers, the result cannot hold true for all Middle East countries. -Correlation between number of DSL Subscribers and ICT Export in OECD The variables number of DSL Subscribers and ICT Export in OCED countries is also subjected to the computation for Pearson’s correlation. The P-value is equal to 0.153, which is greater than 5%. It means that there is no correlation between DSL subscribers and ICT export in OECD countries. The value for the Regression’s Coefficient is 0.267 which means that there is a correlation but it is not too strong. The R2 value for the variables is equal to 0.072. It means only 3% of the change in the number of Broadband Subscribers in OECD countries is related to ICT Export. It supports the idea that there is no correlation between DSL subscribers and ICT export. The graph below shows this regression. Iran is the second largest oil producer among the Oil Producing and Exporting Countries (OPEC). Furthermore, it has the worlds second largest reserves of natural gas. This chapter analyses the ICT situation in Iran and it will evaluate the Internet and Mobile penetration in the Middle East region. The research tries to identify the obstacles for development of ICT in Iran and to serve as a basis in the proposal of new policies. There are many active companies competing in the DSL arena in Iran. The major companies and their activities are listed below: Almost all of the governments of Middle Eastern countries control the communication and information media services. Internet access is especially subjected to many restrictions. Some of the most important restrictions are (a) Religious restrictions, (b) Political restrictions, (c) Language restrictions, (d) Speed limitations, (e) Cost of service, (f) Technical problems (disruptions in connectivity). The reasons for most of these problems are the incompatible infrastructures, lack of skill for supporting services, scarcity of local websites, insufficiency for applied economy and life. There are some other local obstacles in each country that complicates the infiltration of Internet access. The table below shows the population and internet users. Moreover, the percentage of the total population with internet access will also be shown. Figure below presents the number of internet users. Iran has the most number of internet users and Bahrain and Iraq have the least number of internet users. The comparison between internet penetration in 2000 and 2005 in this region shows that the growth of all countries is notable. The total growth of Internet users in Middle East from 2000 to the latest data available is 491.4%.   Each country showed an increase in their rate of access to Internet by at least 100%. The figure below displays the percentage of population with access to Internet. The internet user share of population in Israel is the highest while the corresponding shares in Iraq and Yemen remained to be very low. As Figure 2 shows, 51% of Israel’s population have access to internet. United Arab Emirate with 36%, Qatar with 27%, Kuwait with 25%, and Bahrain with 21% followed Israel in the list. Other countries do not enjoy the same privileges where only a low percentage of the total population have access to the internet. The share of Internet users in each country to the aggregate sum of Internet users in Middle East is calculated in the table below. Internet penetration and population of each country can influence the share of Internet users to the sum of Internet users in the Middle East. However, the table below demonstrates the level of interest of each country to communicate with other countries in economic and cultural aspects. The results show that in 2005, Iran has almost 39% of Internet user in Middle East. Israel with 19%, Saudi Arabia with 13%, and United Arab Emirates with 7% has more contributions to assemble total Internet users in Middle East. Figure below displays the share of each country in total Internet users of Middle East. The figure below shows correlation between Mobile population coverage and GDP per capita. The Pearsons correlation is used to find a correlation between GDP and Internet user, GDP and Mobile user, GDP and Fixed telephone. The value of Pearson’s coefficients and the value of P-values show no relationship between GDP and three factors. The GDP does not have any influence in the penetration of Internet, Mobile, and Fixed telephone in the Middle East. The graph below shows a negative relation between the number of DSL subscribers and Monthly charge. It means that countries with lower Monthly charge have more DSL subscribers. The distribution of countries in the graph is very wide and far from the correlation line, which means that correlation is weak.   The Pearsons correlation is used to find a correlation between the variables Population and Internet Users. The Pearson’s coefficient is equal 0.784. It shows that the relationship between Population and Internet users is positive and it implies direct association. P-value is equal to 0.001 and the value is between 0 and 0.5. It means there is a direct relation between two factors. The graph below shows that there is a direct relationship between Population and Internet users. It shows that countries with more population tend to have more Internet users. The Graph below shows this regression. The Regression’s Coefficient is 0.784 and R2 is equal 0.614. It means 61% of the change in the number of Internet Users in Middle East countries is related to population. The graph below shows the relation between all variables. Relationship of each variable in the distribution’s Matrix is determined with other variables in Matrix through the row and column.

Design And Construction Fundamentals Of Earth Dams Environmental Sciences Essay

Design And Construction Fundamentals Of Earth Dams Environmental Sciences Essay This paper focuses on earth dams, one of the oldest earth dams. Forming service reservoir for domestic water supply and irrigation purpose, earth dams comprise the most numerous class. The design and construction of Earth dams are complex because of the nature of the varying foundation conditions and the different properties of the materials available for the construction of the embankment. Last but not least, an understanding of the potential failure of Earth dams is important in the design and construction process of the Earth dams. Earth dams, also called earthen or earth-filled dams are generally built in or near drainage line which has the variety of purposes including domestic water supplies, agricultural irrigation, water for landscape improvement and others. One advantage of the Earth dams is because it can adapt to a weak foundation provided proper consideration is given to the foundation and design of the Earth dams. However, failure of any important part of the Earth dams such as seepage, structural and foundation will lead to the collapse of the whole dam. Types of Earth Dams Constructed as a simple homogenous embankment of well compacted earth, earth dams are classified as Homogenous Earth Dams, Zoned Earth Dams and Diaphragm Dams. A brief discussion of the types of dams is as follow: Homogenous Earth Dam is a kind of common earth dams which consist of two main components; the impervious to semi-pervious structure and the toe filter and the drain. The purpose of the filter and the drain is to provide a through way for seepage to exit the dam structure without causing erosion. This type of dam is usually built on an impervious foundation such as solid rock or clay. The next type of Earth dam is Diaphragm Dam. A diaphragm dam, can be used when there is no impervious layer below the dam and modification of the dam can be made to suit at an impervious layer. Besides, this type of dam is limited to a height of 8.0m in order to keep seepage forces at a safe level. Last type of Earth Dam is Zoned Dam. A Zoned Dam is known to be the most efficient use of soil as each material is used to its greatest potential. The slope protection protects the shoulder from erosion and wave action, the core retains the water and the shoulders stabilize the core. Lastly, figure 1 shows the 3 types of earth dams. Figure 1. Cross section of Homogenous Earth dam, Zoned earth Dam and Diaphragm Dams 2. DESIGN OF EARTH DAM Earth dam is built for the purpose of storing water and is made of compacted earth. It is usually more convenient when concrete is expensive and timber is scarce. 2.1 Foundation A site investigation should be conducted prior to construction so as to investigate the nature of the foundation. By knowing the actual foundation condition at site, the earth dam can then be designed according to it. A dam foundation is said to be adequate if it is capable of providing a stable support for the embankment under all condition of saturation and loading and that it provide enough resistance to seepage to avoid excessive loss of water (Bureau of reclamation 1987). According to Bureau of reclamation (1987), dam foundation can be generally classified into three types namely foundations of rock, foundations of coarse-grained material and foundation of fine-grained material. These foundations may need to be treated to stabilize any weakness as well as to reduce seepage. For instance, coarse-grained, pervious foundations present no difficulties in the matter of settlement or stability whereas a fine-grained, weak foundation is subject to settlement or displacement usually present no problem in seepage. Rock foundation on the other hand must be checked for erosive leakage and excessive uplift pressure. If such conditions exist, grouting to the foundation must be considered. 2.2 Soil Earth dam is usually built with clay, sand and gravel and hence is also known as earth fill dam. The type of soil used in the construction of an earth dam must be suitable to allow for optimum compaction as well to reduce seepage. Soil permeability is one of important criteria to be considered in dam design, seepage-confinement units, drainage and other structural elements (Goldin, AL Rasskazov, LN 1992). Seepage usually occurs in fine-grained soils such, with greater permeability, as well as in some coarse-grained soils (Goldin, AL Rasskazov, LN 1992). Higher frictional resistance and greater permeability in granular soils is the reason for its greater stability as compared to cohesive soils. Greater permeability permits rapid dissipation of pore water pressures resulting from compressive forces. 2.3 Embankment In determining the height of the embankment, it is necessary to allocate for a settlement between 5 to 10 percent. This is to prevent its height becoming lower than the spillway height (Figure 1) since settlement is unavoidable despite having a good compaction since air and water out are being forced out of the voids by the weight of the dam, hence causing consolidation (Shaw, R Smout, I 2009). During compaction, equal effort should be applied throughout the dam to prevent differential settlement. The minimum compaction effort should not be less than 95% of the Standard Maximum Dry Density (Department of Primary Industries and Water 2008). The stability of the embankment depends largely on its ability to resist shear stress which comes from internally applied loads such as the weight of the soil and the embankment slopes, and externally applied loads such as reservoir and earthquake loads. As mentioned earlier, steeper slopes can be adopted for granular soils since they are more stable. In contrast, a gentler slope needs to be applied for homogenous material with low permeability. Figure 1. Cross section of an earth dam 2.4 Spillway Spillway plays an important role in earth dam since it allows excessive water to flow without overtopping the dam wall. There are two types of spillway namely the cut spillway (Figure 2) and natural spillway. Figure 2. The position of a cut spillway In order to reduce water velocity and subsequently minimize erosion, a gentle slope for the spillway must be provided. However, for steep slope, loose stones or geotextile can be provided to reduce erosion. Apart from that, adequate capacity of the spillway must be provided to prevent overtopping and to enable the spillway to effectively handle run-off. 3. CONSTRUCTION ON EARTH DAMS Stripping Organic soil and vegetation must be removed from the area that will covered by the dam base. The removed organic soil are stockpiled and used on the downstream slope of the fill. Key trench Key trench which is also known as cutoff trench is excavated below the base of the fill to a minimum of three feet deep for dam with 10 to 12 feet height. The key trench is included in the dam design to secure the dam to the base material and to prevent seepage under the fill. Diversion tunnel Diversion channels are excavated before the dam can be constructed. This tunnel often lined with concrete. The tunnel is built around the dam construction area at one side of the valley. In the drill holes, explosive materials are placed and blasting will takes place. The soil or broken rock is then removed. The steps are repeated until the tunnel is completed. Figure : Building a diversion channel In Figure, after the dam construction is completed, the diversion channel is closed o allow the lake to begin filling. Figure : Closure of diversion tunnel Cofferdam In summer, the construction on diverting the river starts when the river levels are low. At the upstream of the upstream of the main dam construction area, small dam which is also called as cofferdam are built. It is built using earth-moving equipment. The cofferdam will acts as a barrier to the river and the water will flow to the diversion tunnels. The second cofferdam will be built downstream of the main dam construction area. At this area, the cofferdam will prevent the river flow to flow back into the construction area. Figure : Cofferdams act as barriers to the river Foundation Grouting Grouting consists of lines or a line of holes that are drilled into the dam foundation. The types of foundation grouting are curtain and consolidation grouting. Curtain grouting Curtain grouting consists of a single row of gout holes that are drilled and grouted in sequence by packer testing to the base of the permeable rock or to a depth that acceptable hydraulic gradients are achieved (Fell et al 2005). Based on Figure, primary holes are drilled first. The last hole spacing will normally be 1.5m or 4m, but also may be as close as 0.5m (Fell et al 2005). This approach allows control over the efficiency of the curtain grouting. Figure : Curtain and consolidation grouting (Fell et al, 2005) Figure :Grouting downstage with packer (WRC, 1981) Fill construction Earth dam is usually constructed from impervious material which is clay or clay-based material. The construction materials, taken from the surrounding area have to be placed and compacted horizontally in the fill. Dry soil are usually added with moisture and compaction equipment such as a sheepsfoot packer used to obtain the proper compaction. The construction started by filling the cutoff trench with well-compacted material and six inch layers is added until the maximum height is obtained. The top of the dam at the center of the draw is usually built 10 per cent higher than the design to allow settlement of the fill. Based on Figure, a riparian pipe is placed through the bottom of the fill and a frost-free valve is placed on the riparian pipe. This pipe and valve system function is to allow water to be released downstream to other water storage facilities during water shortages. Figure : Elevation view of dam 4. POTENTIAL FAILURES OF EARTH DAMS Potential failures of dams have always been great importance and much attention has been given to safety evaluation and research due to their disastrous effects. According to Fell, MacGregor, Stapledon and Bell (2005), 79% of Earth dams with less than 30m high suffer more failures than higher dams. This may reflect better design, monitoring and surveillance of larger dams. Potential failures of earth dam can be grouped into three categories: Hydraulics failure, seepage failure and structural failures. A detail discussion of the types of potential failure of earth dam is as follow: 4.1 Hydraulics Failure Hydraulics failure occurs by the surface erosion of the dam by water. Hydraulics failure is due to several reasons. One of hydraulics failure is overtopping of dams. Overtopping failure occurs when the level of the reservoir exceeds the capacity of the dam. According to Fell, MacGregor, Stapledon and Bell (2005), over-topping is one of the main causes of failure in Earth dams. Overtopping may also be caused by insufficient freeboard provided. Next, erosion of upstream force due to continuous wave action caused erosion of the dam. However, this can be avoided if the surface is protected by stone rip-rap and filter. The next reason is due to erosion of downstream slope by rain water. Although the downstream face of the embankment is not affected by reservoir water, it may get eroded by heavy rain flowing down the face of the dam, causing the formation of gullies and finally collapse of the whole dam. 4.2 Seepage failure Seepage failure is also known as piping failure. Seepage failures are generally caused by pervious foundation, leakage through embankments, conduit leakage and sloughing. All dams have seepage as the impounded water seeks path of least resistance through the dam structure and its foundation. If the surface seepage intersects the upstream face of the dam, erosion may occur which will lead to possible failure of the dam. Typical method used to control the quantity of seepage is rock fills installed at the downstream toe or gravel blankets to intersect the line of seepage before it reaches downstream toe as shown in Figure 1. Figure 1. Seepage through a dam or embankment with rock toe or gravel blanket. 4.3 Structural Failure Structural failure includes failure of the upstream, downstream slopes of the earth dam, foundation as well as cracking deformation and settlement of the dam structure that may lead to overtopping or seepage failure. Slides in Embankment occur when the slopes are too steep for the shear strength of the embankment material to resist the stresses imposed. Failure of this type usually cause by faulty design and construction. As for foundation failure, it occurs because of excessive pore water pressure which reduces the strength of the soil which it may not be able to resist the shear stresses induced by the embankment. Furthermore, damage caused by burrowing animals lead to structural failure. This causes seepage water to flow out quickly, carrying fine materials along which consequently leads to piping failure within the structure of the dam and finally lead to a complete collapse of the dam. 5. CONCLUSION

The Crucible: Insight Of Hale, Elizabeth And John :: Essay on The Crucible

The Crucible, a container that resists hear or the hollow at the bottom of an ore furnace. However its connotations include melting pot, in the symbolic sense, and the bearing of a cross. Elizabeth, John Proctor’s wife; a cold, childless woman who is an upright character who cannot forgive her husband’s adultery until just before he died: she is accused of being a witch. Reverend Hale, a self-proclaimed expert on witchcraft; at the play’s end tries to save the accused. John Proctor, a good man with human failures and a hidden secret, a affair with Abigail, he is often the voice of reason in the play; accused of witchcraft.â€Å"I do not judge you. The magistrate that sits in your heart judges you.† This is where Elizabeth suspects that John has committed adultery, but knows how good of man he is and tries to look over it. â€Å"Adultery, John.† This is where John tells her and she makes it sound like it is news to her even though she has known for awhile. She is trying to have John have a â€Å"good† name and not be a name that everyone discards. â€Å"No, sir.† Here she is protecting his name but she doesn’t know that John has just came out and said that he committed lechery. She thought that she was saving him but she was actually making it worse for him.â€Å"I mean to crush him utterly if he has shown his face.† Here he is talking about if he ever encountered the Devil that he would literally kick his ass. This shows how he is a hippercrite against being a Puritan. Even though he is a religious man he still has the human character of having an evil side to himself.â€Å"But I will cut off my hand before I ever reach for you again.† John is talking to Abigail and how he is finished with seeing her and that he doesn’t want any part of her. John goes through from being amoral to immoral and then to moral, then back to amoral at the end. â€Å"It’s winter in here yet.† Elizabeth and John were talking about how he was working all day seeding even though he was at Salem to see what the fuss was all about. Here he shows his character toward Elizabeth by lying to her and she can’t trust him. â€Å"Let Rebecca go like a saint, for me it is a fraud.

Questions of Ethics In Computer Systems and Their Future 1) Identify and discuss security issues and considerations evident for Information Systems And computerization in the brokerage industry. ( Think about how the Internet has already influenced trading.) "The technology is getting ahead of regulators" claims David Weissman, director of money and technology at Forrester Research Inc., in Cambridge, Mass. If one is to believe the quote above it sounds very ominous for the regulators and the government to attempt to even bring this media under any kind of regulation. But, what is it that they the government agencies truly are looking to regulate? If you take to the argument that this media, the Internet is truly a public access network, then the control to which they would like to extend to it would be the most regulated public access system in history. What I believe the attempt here is to regulate through censorship. Since it is almost impossible to censor the phone networks without actually eaves dropping on your phone, they have decided to regulate and censor your written word. The danger in this is what you write as an opinion may be construed by that government regulator as a violation of some regulatory act. The flip side to this is if you did this through another medium such as the phone system nothing would ever come it. The bigger question here is how much government do people want in there lives? The Internet was brought into the picture for the public as the next great technology of this century. It is without a doubt as big if not bigger than any other public means of communication that has come before it. With that in mind I think the government is trying to extract it's pound of flesh for what they believe is missed revenue dollars that could be made in the form of tax regulations. "There are probably insiders touting stocks on the Internet either anonymously or under assumed names," said Mary Schapiro, president of the National Association of Securities Dealers, which oversees the NASDAQ market. The argument that they are both (the government and NASDAQ) currently running with is the "protection of the investor". When one looks at NASDAQ's complaint it is fairly superficial, for them it is clearly a loss of income for their trading enviorment, for the government it is a loss of taxes that could be derived f... ...s or messages because the central computer in the office will know your where abouts in the office at any time as you pass through any door.

Write a balanced equation for the reaction between O2 and H2. 2H2 + O2 ==> 2H2O E. What is the function/purpose of the bromothymol blue in the CO2 experiment? The Bromothymol blue changed color from clue to green and then it turned yellow. After the CO2 was mixed with water, I think carbonic acid was formed. This can measure the amount of CO2 present, a lot of CO2 will show yellow and very little or no CO2, the bromothymol will remain blue. F. Bromothymol blue is blue in the presence of basic solutions, and yellow in the presence of acidic solutions.If your solution is a murky green, what might you assume about the solution? I would assume that the solution is neutral if it is a murky green. With acidic solution, the blue turns yellow. Flow Chart 1. Fill four test tubes with ? distilled water. 2. Add 2-3 drops of bromthymol blue to each test. Part 1: Oxygen 3. Add a small amount of manganese dioxide in an empty test tube. Then add a small amount of Hydrogen Peroxide. 4. Immediately stopper the test tube. 5. Take the stopper out. 6. Repeat these steps for Part 2: Hydrogen and Part 3: Carbon. 7. Record data and answer questions.
