Satan :: essays research papers

Apple has two lawsuits pending that involve rumor-tracking Web sites. In Apple Computer v. Doe No. 1, et al. (or Apple v. Does for short), the company is suing up to 25 unnamed individuals for misappropriation of trade secrets—specifically, leaking Apple’s confidential information about an unreleased audio product code-named â€Å"Asteroid† to Think Secret, AppleInsider, and Jason O’Grady’s PowerPage. As part of the discovery process, Apple obtained subpoenas for all three sites for any and all information related to â€Å"Asteroid,† including the identity of all people who leaked the information, or communications that might reveal said identities. None of the sites is a defendant in the Does suit, though Apple has made clear that they could be named as defendants if evidence shows that they knowingly published Apple’s trade secrets (and Think Secret is a defendant in a second lawsuit not related to â€Å"Asteroid†). Both Think Secret and AppleInsider have their own e-mail service, so obtaining information about their e-mail records and messages would require subpoenaing the sites themselves, invoking difficulties about journalist privileges. When Apple learned that PowerPage used an external e-mail provider, the company’s legal team found its path of least resistance. Nfox has gone beyond refusal to contest the subpoena—the ISP refused to promise O’Grady that it would not comply with the subpoena before appeals were exhausted. That’s when the Electronic Frontier Foundation, representing the three sites, went to court seeking a protective order on O’Grady’s behalf to prevent Nfox from turning over the information to Apple. On March 4, lawyers for Apple and for the three subpoenaed sites met in the San Jose courtroom of Superior Court Judge James P. Kleinberg. They were arguing over the sites’ motion for a protective order barring Nfox from honoring Apple’s subpoenas. It was an uphill battle, because one day earlier, Judge Kleinberg tentatively ruled in Apple’s favor. On March 11, the Judge formalized his preliminary decision, denying the motion for the protective order, leaving Nfox free to honor Apple’s subpoenas and turn over all information from O’Grady’s e-mail related to â€Å"Asteroid,† including that which may identify the person who sent it to the sites. In the 13-page ruling, Kleinberg essentially told the three sites (the ones who moved to have the subpoenas quashed, hence their reference as movants in the decision) that their status as journalists does not matter—if they had Pulitzer Prizes, they’d still have to honor the subpoenas.

Active Citizen

I’m going to become an active citizen in four simply steps which are learn about the issues, figure out what is not working and try to come up with solutions, take action, and make sure to talk to others. Step 1: read a good newspaper or website like www. cp24. com. Find out what is going on and what’s good and bad about my city, state, country, and the world. Step 2: start by looking in my city you I don’t get confused. To do this, I will need to make a list of categories, which will help me break down all the problems.Some examples are: Are there problems with the public education or catholic system? Is there a lack of community in my neighborhood? Step 3: write letters, call, and meet with your elected officials. I will make my voice be heard by writing to the media or even just starting a blog or website. I can host a creative fundraising project or volunteer with an organization. Step 4: make as many people as possible to be concerned about each problem that ’s happening with in our community, so that they can take their own actions and the problem can get solved.The most important thing is putting the word out there so people can act wisely. The three most significant lessons about citizenship that I will take away from this course are the freedom of speech, the freedom of voting, and the freedom of religion. Freedom of speech is extremely important because it refers to the right of an individual to express his/her views about matter of interest to him/her with the freedom of press which means the freedom of writing which both represent their thoughts.Freedom of speech gives people the right to express their opinions without being arrested and thrown to jail. The freedom of voting is also important because it lets people choose the person they feel will represent them better. Freedom of voting is also important because a democratic government can only function when as many people as possible are able to participate in the electo ral process.Freedom of religion is important because people need to feel that they are able to have some sort of influence that is free from the external control. Individual need to feel some sort of level of spiritual fulfillment and should be able to choose freely how that path is taken. Freedom of religion is so important because no matter what ones religion is all of them have one thing in common. It is also important because people wont be force to follow certain customs or beliefs like they used to back in the days.

Earthquake resistance design

Columns can sustain two types of Damage, namely axial- flexural (or combined compression bending) Failure and shear failure. Shear damage is brittle and must be avoided in columns as by providing transverse ties at close spacing which carry the horizontal shear forces and hold concrete and vertical bars together. Horizontal Bands and its Role: Horizontal bands are the most important Earthquake-resistant feature in masonry buildings, since it holds a masonry building as a Single unit by tying all the walls together. There are four types of bands in a typical Masonry building, namely gable band, roof band, lintel band and plinth band. Lintel band is the most Important of all, since it ties the walls together and also breaks the monotonous continuity of wall.The gable band is employed only in Buildings with pitched or sloped roofs. In buildings with flat R. C or reinforced brick roofs, the Roof band is not required. In buildings with pitched r sloped roof, the Roof band is very importan t. Plinth bands are primarily used where uneven settlement of foundation in soil undergoes bending and pulling actions. It will be better to use ARC bands Shear Wall: Reinforced concrete buildings often have vertical plate-like ARC walls called Shear Walls. These walls generally start at foundation level and are contain souse throughout the building height. Their thickness varies from mm to mm. Shear walls are usually provided along both length and width of buildings.Shear Core Shear walls are like vertically-oriented wide beams that carry earthquake odds downwards to the foundation. Just like reinforced concrete (ARC) beams and columns, ARC 6 shear walls also perform much better if designed to be ductile.. Shear walls, if provide around the elevator core or stair well is known as shear core. Boundary Elements: Under the large overturning effects caused by horizontal earthquake forces, edges of shear walls experience high compressive and tensile stresses. To ensure that shear walls behave in a ductile way, concrete in the wall end regions must be reinforced in a special manner to sustain these load reversals without loosing strength.End regions of a wall with increased infotainment are called boundary elements which have high bending strength. Boundary Elements (Design, Location) Short and Long Columns: During past earthquakes, reinforced concrete (ARC) frame buildings that have columns of different heights within one storey, suffered more damage in the shorter columns as compared to taller columns in the same storey. Short Column Behavior: Poor behavior of short columns is due to the fact that in an earthquake, a tall column and a short column of same cross-section move horizontally by same amount. However, the short column is stiffer as compared to the tall column, ND it attracts larger earthquake force. Therefore it cause X-shaped cracks.Short Column (Failure, Location with Mezzanine floor) Stiffness of a column means resistance to deformation -? the larger is the stiffness, larger is the force required to deform it. This behavior is called Short Column Effect. Design Phenomenon: 7 If it is not possible to avoid short columns, this effect must be addressed in structural design. As per Indian Standard the reinforcement must extend beyond the short column into the columns vertically above. In case of stone or brick masonry the width has to be increased accordingly for short column. BEAM COLUMN JOINT: The points where the beams and columns intersect is a beam column joint. Since they too made of same material we can't expect to have more strength. So have to take care on these unavoidable joints.During earthquake the upper bars and lower bars act in a different direction causing elongation or damage of joint. Design Strategy: In design practice large column size, having large closed loops are placed inside. These should follow some design specification. Normally we will go for the anchoring of the bars at the ends. Micro concreting can b e gone in the congested junction. Beam Column Joint (Location, Failure without proper anchorage) Hidden Beams: These are also called as concealed beams which have their depth equal to that of the slab. These can be provided either on longer or on the shorter span. When provided along longer span it is found that the load carrying capacity increase to 135% with an economical increase of just 0. 4 -? 0. 5%.These beams are designed for negative bending moment which is caused due to load reversal expected during earthquake. 8 Hidden Beam Plastic Hinge: As moment increases, the linear stress distribution form persists and the extreme fiber stress reaches the yield stress value. Further increase in the bending moment cannot produce any increased fiber-stress but causes yield to spread into the inner fibers. As the bending moment Increases more and more fibers reach the yield stress until the final state, the whole of the section will yield. The complete yielding across the section of a be am is termed as plastic hinge. The section now carries the maximum bending moment without strain hardening taking place. The beam can carry no further load.Any further load will only result in increased deflection. The beam will behave as if t is hinged at the plastic section and a condition of collapse has been reached. Reduced Beam Section: This is a section of beam which is provided along the length of steel beams. These will have their area of cross section lesser than the proceeding section to an extent that it will just act as a plastic hinge. In case of steel section also a circular arc will be cut in the required flange portion of span. Reduced Beam Section Pre tensioning Technique: In case Of domes and shell Structures, the lateral thrust experienced will be more. This fault is answered well by pre tensioned concrete.In case of huge trustees like nuclear 9 rectors, large spanning domes we will be having a thin walled cylindrical tube of diameter about 10 to 15 CM and steel rods will be packed tightly. Pre tension elements (After & Before Concreting) Then stressing will be done as per design and then the micro concrete is injected in pressure into the tube. This setup is then done with normal concreting. It will resist the lateral thrust in an effective manner. Techniques to Adopt on Sky Scrappers: While speaking about large multistoried buildings we can't simply go in for normal strengthening of beams, columns, and other structural elements. There we had an alternative to speak about some elements such as Bearing, Bracing, Friction pendulum and Dampers which are primarily meant to take Vibration produced by lateral force.Rubber Bearings: Rubber bearings are made from layers Of rubber with thin steel plates between them, and a thick steel plate on the top and bottom. The bearings are placed between the bottom of a building and its foundation . The bearings are designed to be very stiff and strong for vertical load to carry the weight of the building an d designed to be much weaker for horizontal loads, so that they can move sideways due to lateral thrust. Rubber Bearing Viscous Dampers Viscous Dampers: Viscous fluid dampers are meant as shock absorbers. They consist of a closed cylinder containing a viscous fluid and a piston having small holes in its head. As the 10 piston move in and out of the cylinder oil is forced in and out causing friction.The damper is usually installed as part of a building's bracing system using single diagonals. As the building sways to and fro, the piston is forced In and out of the cylinder. Friction Dampers: Friction dampers are designed to have moving parts that will slide over each other. The damper is made up from a set Of steel plates, with slotted holes in hem, and they are bolted together. At high enough forces, the plates can slide over each other creating friction causing energy dissipation. The plates are specially treated to increase the friction between them. Friction Dampers Cross Bearing s (In foundation) Cross Bracing: These are very common in case of vertical load distribution.But we can also adopt this technique to foundation, in which the entire building will be laid in a cross horizontal bracing rather than placing it directly on foundation. It will distribute the load to joints and through foundation finally. Friction bearing (Location, Appearance) 11 Friction Pendulum: Considering about the large multistory buildings, we can always expect some appreciable movement in it base due to the vibration. Instead to resist against it completely we can allow the structure to deform at its foundation level by provision of friction pendulum without damaging the structural integrity.

Ethics and Corporate Responsibility in the Workplace and the World Essay

Ethics and corporate responsibility in the workplace and the world is becoming a center of attention. There are many things going on in the workplace that different agencies and people are looking into while placing the blame on the appropriate source. In this paper, a scenario is presented. The scenario involved PharmaCARE and its subsidiary, CompCARE are reviewed and certain questions are being asked for clarity. The paper will look at the stakeholders in this scenario. The paper will do it best to analyze the ethics of PharmaCARE’s treatment of the Colberia’s indigenous population and its rank-and –file workers versus that of its executives. In additionally, the paper will look at the situation concerning three workers, Donna, Tom, and Ayesha under the supervision of Allen. The study of how whistleblowing, opportunities, and protection could help Allen stop the unethical of CompCare. An assessment of PharmaCARE’s environmental creativity with the Colberian activities. The paper will address the original purpose of and changes to Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The paper will now look at the shareholders in this scenario. The shareholders are major players in an organization or corporation. The Merriam-Webster dictionary defines a â€Å"shareholder as one that holds or owns a share in a company† (Shareholder, 2013). A synonym of a shareholder is stakeholder and this is someone who has interest in the company. Therefore, the shareholders of this scenario are Allen, Donna, Ayesha, Tom, CompCARE, PharmaCARE, WellCo, and the Colberians. Allen, Donna, Ayesha, and Tom are employees of CompCARE. They are stakeholders in this scenario because they work for CompCARE and this is how they make their living. They want the company to be successful, but at what cost will it cost them. The Colberians are the people who labor to make the drug, while getting paid $1.00 a day and living in poverty. PharmaCARE is the mother company of CompCARE and its goal is to profit off of CompCARE by any means necessary. WellCo brought the  CompCARE from PharmaCARE seeing the profit it could make in this deal. Each shareholder plays a significant part in making sure the CompCARE is successful. The paper will now look analyze the ethics of PharmaCARE treatment of the Colberians. PharmaCARE has a company in African and found people there willing to share information about local remedies and could supply workers willing to work for $1.00 a day. PharmaCARE probably look at this as a coal mine and struck the deal. This process is unethical in every way. One reason it is unethical, the employees at PharmaCARE is not working for a $1.00 a day wage nor are they living in primitive huts. The employees of PharmaCARE have electricity and running water while the Colberians do not get to enjoy this luxury. The World Trade Organization, WTO established guidelines concerning labor rights and standards. â€Å"Moreover, precisely because third world workers are terribly exploited, their employees will pass on much of the cost of improvements in labor standards achieved through international trade treaties to their employees in the form of lower wages† (Global Issues, 2013). PharmaCARE knew the way it was treating the Colberians was not ethical; the company could not behave in this fashion in the United States. PharmaCARE teamed with some toxic leaders in fatting its profit margin. The welfare of the Colberians did not concern them in any way. Hellriegel and Slocum noted a concern for a global team. The global team would have benefited PharmaCARE tremendously. â€Å"The global team helps to define common features of goods and services that will appeal to customers in different countries. The global team members from different countries can provide insight into an input about these unique market needs and requirements for specific attributes of goods and services† (Hellrigel & Slocum, 2011, p.360). A company wants to be correct in dealing with foreigners because if anything is done wrong eventually the world will find out. In this scenario, the executives profit, while the workers receive scraps. The paper will now turn it focus on the workers insi de CompCARE and could termination be consider legal in this scenario. The workers are Allen, Ayesha, Donna, and Tom. Allen is the manager and was responsibility to make sure his staff was not in any health nor safety  threat. In the case with Ayesha, she wanted to be promoted and nothing happen. She filed a complaint with the EEOC. â€Å"The EEOC was created to increase job opportunities for women and minorities and to help end discrimination based on race, color, religion, disability, gender, or national origin in any personnel action† (Boone & Kurtz, 2012, p. 61). Allen could have avoided this by putting Ayesha on a supervisor track. Allen could have been a role model for Ayesha, while showing her the responsibility of a supervisor. Allen should have talked to Ayesha and giving her pointers on what she needed to do to be considered for a supervisor job. In the case of Donna, she never was one to stay out of work. She had a perfect attendance until the discovery of mold was found. She became ill because nothing was done to rectify the mold problem. Therefore, Allen do not have a just cause to fire Donna knowing the reason of her illness. She continued to work until she could no longer and filed for worker compensation. â€Å"Any employee, irrespective of their length of service, who is dismissed or subjected to a detriment for certain health and safety reasons, would have a potential claim against their employer† (Calcott, 2011, p.12). In the case of Tom, he wanted something done about the mold problem. Tom was a supervisor at CompCARE and he reported to Allen. Tom noticed how all the workers were getting sick and took action. He informed Allen about the sir quality in the lab. Tom did the right thing in reporting all problems to his superior. The assumed Tom waited and went to Allen again to do something about the air quality. The problem gotten worsen and Tom threatened to turn the company in to OSHA. Tom would be consider a whistleblower. â€Å"A whistleblower exposes the misdeeds of others in organizations† (Schermerhorn, 2010, p.100). The Whistleblower Protection Act of 1989 prohibits an employee from getting fired for telling on unethical conduct. The paper will now look at how Allen could have benefit by supporting his employees and himself. Allen knew something was not right and yet he did nothing when the problem was not fix. â€Å"Employers are well aware of their extensive responsibilities to employees under the Health and Safety at Work Act 1974† (Calcott, 2011, p.12). In the role Allen have, he was obligated and held the responsibility to protect his staff. Allen reported to his boss as to what was going on, therefore he should took the next steps in finding help for his employees. Allen could have benefited himself by having a clear conscious he did what was right.  He would have been free from any prosecution the employees would have filed on the company. He would have been protected under the Whistleblower Act as well. Allen’s health was just as much danger as his staff and this should have been enough to make him tell authority. PharmaCARE’s renders a purported environmental stewardship is worst and the company’s public stance should carry an obligation to be a leader in environmental matters. PharmaCARE should be more concern about Colberians’ environment. PharmaCARE should want to help the people who is producing their product. They could help with building homes for the Colberians, by knowing their conditions. The executives live in nice places with running water and electricity. PharmaCARE can set up a fund in order to educate the people of Colberia. Teaching and showing people how to be more efficient will help PharmaCARE profit more. The people will be loyal to the company helping them. PharmaCARE can help the Colberians to be more productivity in everyday life. When a company goes in a foreign country to do business it should make sure of the country’s policy. Companies move their business to foreign countries are still liable if something happen. The company should be willing to help build the area up the workers live in. Building roadways to carry PharmaCARE’s drugs is a significant matter. The WTO is cutting down on companies that are no treating foreigners’ right. This is in health and safety as well as in the United States. The WTO is an advocate for under privilege countries. It protects the right of the workers in poverty countries. There seem to be a big issue regarding children workers but this does not seem the case. However, WTO will not allow any injustice to come to workers in third world countries. â€Å"The WTO’s agreements permit members to take measures to protect not only the environment but also public health, animal health and plant health. However, these measures must be applied in the same way to both national and foreign businesses. In other words, members must not use environmental protection measures as a means of disguising protectionist policies† (WTO, 2013). The author believes now things are getting better because companies know someone is watching them. The next concern to look at concerning this scenario is the Comprehensive Environmental Response, Compensation, and Liability Act. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) à ¢â‚¬Å"is a liability scheme rather than a monitoring program† ( Halbert & Ingulli,  2012, p.207). According to the Environmental Protection Agency â€Å"the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) commonly known as Superfund, was enacted by Congress on December 11, 1980† (CERCLA, 2013). The CERCLA’s function were to assist others when a hazardous substances might endanger others or the environment. The Comprehensive Environmental Response, Compensation, and Liability Act provided accountability of persons accountable for discharges of hazardous waste. It also established a trust fund to make available for cleanup when no guilty party could be acknowledged. The Comprehensive Environmental Response, Compensation, and Liability Act do not support the PharmaCARE scenario. The PharmaCARE is a pharmaceutical company and CERCLA’s target is chemical and petroleum industries. CERCLA will assist when the responsibility people cannot be located. In this scenario the responsible party is known and could have done something about the matter before it got out of hand. The cleanup should fall on PharmaCARE and not CERCLA. There were signs and people to tell the story of what happen and how nothing was done to cease the problem. There were no transporters bringing the mold into the company. The mold grew and causing the air quality to be tamper with. PharmaCare is fully blame for this and should pay for the cleanup and compensate the workers on their health issues. PharmaCARE was bogus and should be made to buy back CompCARE from WellCo. WellCo is an innocent party while things were being withheld from the company. References Boone, G., & Kurtz, D. (2012).

Comparison of Communication and Cognitive Abilities of the Research Paper - 1

Comparison of Communication and Cognitive Abilities of the Bottle-Nosed Dolphin vs. the Chimpanzee - Research Paper Example As the report declares both nose-bottled dolphins and chimpanzees demonstrate social living skills. The two species live in complex but well organized social units. According to Herman, for the social units to operate effectively, young dolphin and chimpanzees undergo thorough training about the rules of the society and this learning is passed down to future generations. During this training, the newborns learn about collaborative and cooperative activities to ensure there is peaceful co-existence with the social units. Moreover, they learn about identity and personalities of the members in the group. While still young, the offspring of bottle-nosed dolphins and chimpanzees spend protracted period with their mothers within the social unit and acts as a chance for wide social learning This paper stresses that like chimpanzees, bottle-nosed dolphins are engaged in complex play behavior. In their social units the two species engage in complex play activities which considered as a way of teaching the members of the group. Moreover, the two species demonstrates creative behaviors. In the case of chimpanzees, they portray creative behaviors as they seek to solve a certain problem. Wyatt notes that there are instances when chimpanzees realize that a child has an edible fruit and tease such a child so that s/he responds by throwing back the fruit thereby getting food. Chimpanzees and dolphins have distinctive natural languages where they produce unique sounds.

Increase of fruit and vegetable consumption by promoting them as an Essay

Increase of fruit and vegetable consumption by promoting them as an alternative to less healthy snacks - Essay Example They calculated factor scores for each participant and examined prospectively the associations between their dietary patterns and colon and rectal cancer risks. Quite astonishingly, the results were quite alarming. The prudent pattern was characterized by higher intakes of fruits, vegetables, legumes, fish, poultry, and whole grains, while the Western pattern, was characterized by higher intakes of red and processed meats, sweets and desserts, French fries, and refined grains. During 12 years of follow-up, they identified 445 cases of colon cancer and 101 cases of rectal cancer. After adjusting for potential confounders, they observed a relative risk for colon cancer of 1.46 (95% confidence interval, 0.97-2.19) when comparing the highest with the lowest quintiles of the Western pattern (P value for trend across quintiles, .02). The prudent pattern had a non-significant inverse association with colon cancer (relative risk for fifth quintile compared with the first, 0.71; 95% confidence interval, 0.50-1.00; P for trend across quintiles, .31). ... and the risk of colon cancer."( Fung, Hu, Fuchs, Gioannucci, Hunter, Stampfer, Colditz, and Willet, Programs in Nutrition, Simmons College, 300 The Fenway, Boston, MA 02115, USA. fung@simmons.edu).1 This paper is targeted at the time-starved office-goers and health conscious people. African Americans have a higher risk for almost all heart-related diseases compared to the native whites for the simple reason that they consume less to moderate amount of fruits and vegetables. Heart disease, obesity, blood pressure, cancer, and diabetes are common forms of disease that can affect them more. Fruits and vegetables provide abundant vitamins and minerals to maintain a healthy body. There are distinct advantages in consuming fruits and vegetables compared to the less healthy snacks. Phy-to-chemicals Despite the fact that we come across food that fills our palate and is easy on the pocket at every street corner, it must be said that most of these food supplements may not be as healthy as one would expect it to be. Fast foods are a mixture of fatty and less healthy substances. This does not in any way take away the gullible replenishment of the youth and office goers. Life on the fast track can be unforgiving. Where does one have the time and inclination to spend time looking for a health specific menu when time is their biggest enemy Walking up to a restaurant to grab a quick bite may sound a tempting proposition, but the fact remains that not all these food are as healthy and nourishing as we think. The gradual side effects could be more harmful and painful than a more planned intake of fresh fruits and vegetables. A growing body of research proved that fruits and vegetables are critical to promoting good health. In fact, fruits and vegetables should be the foundation of a

Organizational error that caused the failure of the space shuttle Essay - 1

Organizational error that caused the failure of the space shuttle Challenger launch - Essay Example Vaughan argues that NASA managers did not break any rules unlike reported before rather abided by them a bit too strictly. She has pointed out that rather it were the rules that kept on getting more and more accommodative each time a mission was accomplished successfully. Thus rules expanded like a rubber band, enclosing more and more dangers which previously turned out to be false assumptions. It was NASA’s culture where something which has worked once was assumed to work every time. O-ring seals were not a new problem but the previous successful launches prepared the managers’ mind that it is an acceptable risk. She argues that rather than developing new paradigms for unexpected consequences, people change the paradigms to accommodate the consequence or discard them at all. According to her, the same happened in the case of O-ring erosion where the risk level was reduced as the risk did not turn out to be as grave as previously thought. However the reduction in gravit y did not mean that the risk cannot become grave once coupled with some other risks. The O-ring erosion, sub-optimal temperatures & unexpected wind shears, all risks were expected to be less than grave, in the original paradigms but people failed to develop new paradigm for the combination. She has agreed that Challenger’s Disaster was a normal accident (p. 415) & normal accident always happen because of failure to develop new paradigms in extremely complex organization.
