Desiree's Baby The 19th century was a difficult time for many women and blacks because of the domination of white men over them. The social and economic hardships they faced in day to day life was a constant reminder of this domination. The social ideology in the story "Desiree's Baby" was powerful and dangerous and held no escape for any character. A woman with small children who lost her husband would face extreme hardships without the support of close family members. One who happened to be down on their luck would not find much sympathy among their peers even with children. Kate Chopin was one of these individuals who was down on her luck with six children. But fortunately had the support and comfort of her mother for a short period before her mother passed away. A friend advised this mother of six children that writing was a way to solve her problems concerning money and help deal with her grief. Maternal love and all the grief from losing loved ones were to be an attribute to the writing proficiency of this literary artist. This period in Louisiana was not tolerant for mixed ancestry and one found to be non-white would be ostracized from the white community. There were some whites in Louisiana who was not racist but they would still have to follow a strict code of segregation and social guidelines or risk social or bodily death. Kate Chopin was born fourteen years before slavery was abolished so must have had strong feeling on the subject. She no doubt saw mixed ancestry in the black communities and realized the cause of it. This story crosses the line into the covert world of mixed ancestry and the problems it produced. The racism in the story is not discussed openly but is prudently mixed in with Armand's atrocious character and his evil soul. Armand's evil was deep as he forsakes his loving wife, infant son, and God. The story some proclaim contributed to Chopin's early success was "Desiree's Baby" in this story she mixed many feminist emotions from maternal love, to a wife's love and devotion to her estranged husband. During this period, some found it tolerable to leave a baby on the doorsteps of a family to provide a chance at a better life. This was an important point in the story when the Monsieur found the baby Desiree near the front gate, it would mean that Desiree would probably never be aware of her biological parents ancestry. The chance a baby with both parents would be dropped off is not logical but was probably a single mother. A single mother knew there was little help to be found and the child would be hard pressed for a descent upbringing socially and economically speaking. Desiree grew into a beautiful and gentle-hearted young woman and soon found a wealthy suitor asking for her hand. This young suitor had known of Desiree's past but was in love and did not care of this seemingly innocent unknown factor of her past. This suitor, Armand Aubigny was racist and wretched but the young bride was in love and looked past his flawed character. The concept of young Armand falling instantly in love after seeing Desiree standing by the gate is a bit suspicious and sounds more like infatuation. The evil in Armand did not come from his parents and the black employees were cheerful when he was growing up so it is an open question concerning his acquired hatred. The blacks were cheerful while his father was alive but was not during Armand's strict management of the L'Abri. Armand had changed to a kinder man after his marriage and the birth of his son and it may have been the only time in his life he was truly happy. The death of his mother while living in France when he was eight years old may have had a precarious effect on his character. The way Madame Valmonde described the L'Abri as "a sad looking place, which for many years had not known the gentle presence of a mistress"(1), may have been a hint at Armands evil nature being tied to having no maternal influence during most of his boyhood. Madame Valmonde noticed the baby's mixed ancestry immediately when she went for a visit, exclaiming out loud at first sight of him "this is not the baby"(2), Desiree thought she was referring to how big the baby had grown. Madame Valmonde looked closely at the baby and new that it was

Calculating pH of a Strong Acid - Chemistry Problems

Calculating pH of a Strong Acid - Chemistry Problems A strong acid is one that completely dissociates into its ions in water. This makes calculating the hydrogen ion concentration, which is the basis of pH, easier than for weak acids. Heres an example of how to determine pH of a strong acid. pH Question What is the pH of a 0.025 M solution of hydrobromic acid (HBr)? Solution to the Problem Hydrobromic Acid or HBr, is a strong acid and will dissociate completely in water to H and Br-. For every mole of HBr, there will be 1 mole of H, so the concentration of H will be the same as the concentration of HBr. Therefore, [H] 0.025 M. pH is calculated by the formula pH - log [H] To solve the problem, enter the concentration of the hydrogen ion. pH - log (0.025)pH -(-1.602)pH 1.602 Answer The pH of a 0.025 M solution of Hydrobromic Acid is 1.602. One quick check to make sure your answer is reasonable is to verify the pH is closer to 1 than to 7 (certainly not higher than this.) Acids have a low pH value. Strong acids typically range in pH from 1 to 3.

Current Issue - Coursework Example Being near green vacant lots was associated with an average heart rate reduction of more than five beats per minute, compared with non-greened lots. Further analysis concluded that the total net reduction in heart rate when near and in view of green vacant lots was more than 15 heart beats a minute. â€Å"We used heart rate as a physiologic marker of acute stress, and the reduction we found suggests a biological link between urban blight reduction strategies like vacant lot greening and reductions in stress,† lead author Dr. Eugenia South, a physician in the department of emergency medicine at the University of Pennsylvania School of Medicine in Philadelphia, said in a university news release. â€Å"Our hypothesis in the earlier published work was that transforming vacant lots from being overrun with weeds and filled with trash to a clean and green space may make it difficult for people to hide weapons and conduct illegal activities such as drug use in or near the space,† South

Networking - Term Paper Example Statistics show that the Internet usage has more than doubled over the last five years. However, research indicates that a majority of Internet users tend to assume that the transfer of data on the Internet is safe, reliable and is not at risk of forgery or hacking. Yang et al. (2012) argues that most Internet processes and services depend on data relayed by the Domain Name System (DNS) through excellent functioning and accurate mapping of domain names that can be understood easily using the IP addresses. Nevertheless, the DNS, which is mainly relied on for this function, does not provide any content protection. This implies that data remains unsecured against any manipulation when being relayed or while in the servers and caches. As a result, identification and avoidance of forged data becomes impossible. It is at this point that the Domain Name System Security Extensions (DNSSEC) becomes useful. DNSSEC, according to Yang et al. (2012) is a technology developed for the purposes of p rotecting data against attacks by digital ‘signing’ so as to provide assurance of its validity to the user. It authenticates the source data by ensuring that the path between the DNS servers and the validating DNS client are secured. The technology has proved remarkably effective in protecting Internet data from forgery, something that DNS has failed to provide. This paper will start by describing the DNSSEC technology in light of what it means and how it works. This will be followed by a SWOT analysis of the technology. The paper will then evaluate the current ethical and legal issues surrounding DNSSEC technology. The essay will also explore the improvements that have occurred over the last two years to DNSSEC technology and provide a suggestion on the improvements warranted on its current usage. Finally, the paper will predict the future role of DNSSEC for both personal and commercial use. It is an acknowledged fact that the Internet has revolutionized the world. Cur rently most parts of the world have Internet connectivity including the remotest regions, thanks to the recent technological advancements, according to Osterweil et al. (2011). Normally, for one to reach another person on the Internet, he, or she must type the recipient’s address on the computer or Internet-enabled phones. The address is usually unique to the individual, making it easy for computers to find each other. The unique identifiers are normally coordinated worldwide using the ICANN. Coordination of the identifiers is very crucial because, without it, the entire world would have a single global Internet, suggests Osterweil et al. (2011). When typing an address, it must first be translated into several systems before the final connection can be established. The translation of the address is performed by the DNS, which does the work of translating addresses such as www.google.com into Internet Protocol (IP) addresses. After the completion of the translation, ICANN then ensures that the addressing system is coordinated so as to ensure peculiarity of addresses. However, recent findings showed that DNS is extremely vulnerable and allows attackers to forge this process of searching for someone or site on the Internet using their address. The attacks are mainly committed in order to take charge of the session such as directing the user to the hijacker’s own deceptive website for a password and account collection. The vulnerability of the DNS has prompted the establishment of the DNSSEC

Comparison Between Virtual Teams and Face-To-Face Teams Research Paper

Comparison Between Virtual Teams and Face-To-Face Teams - Research Paper Example Workers like to interact in teams through teleworks, and flexibility in terms of time is often their top most priority (Kortez, 1999). Social media networks and online calling services have made it all the more convenient to do business through virtual teams. The constraints of distance and time have been minimized to a large extent. While virtual teams are very beneficial for the members in many ways, there are also certain unfavorable outcomes associated with working in this way. For example, employees who have never seen their employers are at risk of losing their jobs anytime. There is often no accountability. Employees have limited access to the company’s resources. This means that more power is assumed by the employers than what they have in the face to face teams. This paper explores several aspects of teamwork in virtual and face-to-face style. II. Building effectiveness a. Managing a virtual team â€Å"Dispersed teams can actually outperform groups that are colocated . To succeed, however, virtual collaboration must be managed in specific ways† (Siebdrat, Hoegl and Ernst, 2009a). ... This provides team members with opportunities to interact face to face and understand one another’s psychology so that when they interact virtually, they are able to draw only true meanings from the conversation. Frequent face to face meetings also allow the members to settle the intercultural differences and reach a culture of respect and harmony for maximal utilization of their potential. b. Member selection â€Å"[T]eams are usually made up of members from different national backgrounds, meaning the members come from different national cultures, possibly speak different languages, and were raised in different countries that may have different value systems† (Staples and Zhao, 2006, p. 389). Member selection in virtual teams is more complicated as a process than it is in face to face teams. This is due to the fact that communication in virtual teams is already affected by lack of face to face meetings and the presence of a medium of communication i.e. technology. Comm unication in virtual teams becomes even more complicated if the members are from different cultures and speak different languages. For virtual teams, it is advisable for the management to recruit only local employees so that all team members speak the same language and can converse with one another without experiencing linguistic barriers. In the face to face teams, management can broaden the criteria for selection and can also welcome foreign employees as body language plays a very important role in face to face meetings and the influence of linguistic barriers is minimized anyway. c. Team process Principles of effective teamwork in virtual teams include but are not limited to realignment of the reward structures, identification of innovative ways to

The opinion of the project is to energy harvesting through flooring, which is built with piezoelectric technology, the electrical energy created by the weight of human footsteps walking around from place to place, which is caught by floor piezoelectric sensors and get compressed and decompressed, then energy is stored and utilized as a power source. The figure (x) here represent the structure of the energy harvesting design in the form of blocks. 3.2. General Description The author has tried to evaluate when a full amount of weight is sensed by the piezoelectric sensors mounted on a platform, and the voltages which generated will be stored in the Battery. The Battery which is charged, further connected to the Mobile Charging Circuit board as appliances. Board consists a USB point, where users may connect cables to charge a mobile phone from the battery charged. The arrangement also consists a 12-volt power supply adapter with voltage regulator, which will provide to the monitoring circuit based on a microcontroller to monitor the output voltage which generated across the sensors using potential divider physics. The level of a voltage generated and whenever human walks through platform the count of the footsteps is to be recorded and displayed on the LCD. LEDs require DC supply to operate. A string of LEDs is mounted below the platform (floor) when the voltage generated by the weight of human footsteps the LEDs will be blink through the microcontroller circuit. Consequently, the voltage which generated using energy harvesting device Piezoelectric Power Generation System is can be utilized within different appliances; mobile charging, street or corridor lighting, bus or airports station lighting, nightclubs, rural areas, charging technologies for electric vehicles, etc. The more power could be generated using the equivalent technique; researchers are investigating in piezoelectricity for bigger designs. 3.3.

Circuit Simulation Specification The figure (x), show the schematic diagram for Piezoelectric Power Generation System Utilizing of Human Footsteps. The schematic diagram is constructed through circuit simulation software; Proteus Design Suite, which is an Electronic Design Automation tool including schematic capture and PCB layout modules. circuit simulators allow the circuit designer to draw a circuit schematic and simulate circuit operation on a personal computer. Circuit simulators provide a very quick and easy way to evaluate a particular design concept without using expensive test equipment or having to procure parts and assemble a breadboard. The components short-term justifications of the system are specified below and more in details will found in the further chapter. Resistor (R) The circuit diagram of the device has 10 resistors [ÃŽÂ ©] and that having different values which 10K, 2.2K, 100K, 330K, and 10K POT. The requirement of this resistor in the circuit is to create specified values of the current and voltage. So, its used to oppose an electric current by producing a voltage drop between its terminals in proportion to the current. Capacitor (C) The function of the capacitor is to store power in form of an electric field and is called as a ceramic disc with some features like high stability. The circuit of a device has been provided with five capacitors with a value of 10 uF/63V, 33 PF, and 470 uF/35V. And to operate the crystal its specified frequency capacitor is used in circuits. Transistors A transistor is a device which is used to make a change in large output with respect to the small input applied to it. In a circuit, 3 terminals BJT (bipolar junction transistor) is used. By the use of the transistor, control large signal at another pair by just applying small input at another pair. Also, it can be used as a switch with the help of small input current as it is a current control device. IC-Regulator IC is an integrated circuit used in various applications. In timing device product used 7805 IC as a 5v voltage regulator. Sometimes there is a voltage fluctuation and so it could not get fixed output voltage. So this 7805 IC provides regulated power supply. The main advantage of this IC is to give constant output voltage even there is a variation in input. Also, current limiting protection is provided in IC itself and for other parts of the circuit as well. Crystal Oscillators Crystal Oscillator is a device that used in electrical circuits in order to create an electrical signal with an accurate frequency. The need for the frequency of the circuit is to keep the path of the time in quartz and provide a stable signal for the device. Seven Segments Display Seven segments display (LCD) is a device that utilized for displaying the status of the circuit. The features of the seven segments display are that it operates in low current.

Do research on area relating to each design problem. gather more information. Develop a cost budget. Apply creative thinking! Complete a schematic design. The blank pieces of paper at the beginning of the chapter now have many schematic symbols with their associated circuit traces. The next step involves the selection of the physical components and breadboarding.

Environmental Protection Must Be Our Top Priority :: Environment Earth Nature, pesticides, pollution

A few years ago, Time magazine published a special issue entitled "The Century's Greatest Minds." It was the fourth in a Time series on the 100 most influential people of the century, this particular issue focusing on "Scientists and Thinkers." On the cover, Albert Einstein is pictured on a psychiatrist's couch, hands crossed over his chest, a depressed look cloaking his face. Dr. Sigmund Freud, seated in a chair near the couch, pen and pad in hand, is leaning in toward Einstein, excitedly waiting to perform some bit of psychoanalysis on the saddened scientist. A framed picture of Jonas Salk rests on the side table; a portrait of John Maynard Keynes hangs from a nail in the wall. In the background, resting atop a bookshelf, is a stone bust of Rachel Carson, author of Silent Spring. She finds herself in quite excellent company not only on the cover, but in the interior of the magazine as well. Carson was the only environmentalist and the only woman featured in the entire issue. Evidently, her impact in the world of "scientists and thinkers" was a tremendous one, and, as mentioned in Matthiessen's Time article, her book, Silent Spring, is "nearly 40 years later . . . still regarded as the cornerstone of the new environmentalism."1 Matthiessen goes on to write that "one shudders to imagine how much more impoverished our habitat would be had Silent Spring not sounded the alarm."2 This is indeed a worthy claim by Mr. Matthiessen, but he correctly uncovers a bigger and more alarming truth when he says, "the damage being done by poison chemicals today is far worse than it was when she wrote the book."3 In fact, since 1962, pesticide use in the US has doubled.4 As an environmentalist (or a "radical" environmentalist, as I am often labeled by members of the mainstream environmental movement), I feel it is my duty as a protector of the Earth's well-being to write this editorial as a means of bringing into the American consciousness a variety of frightening environmental issues. Though some of you may be aware of these problems, I know many are not, and thus may be shocked to learn about the degradation of our Earth and the people living in it. Indeed, I truly believe that "since the dawn of the industrial age, America has behaved like an alcoholic with a good job—prospering despite a lifestyle that jeopardizes the future and ruins much of what is good with irresponsible behavior.
