Scarlet Ibis - 868 Words

Hailey M. Camper Mrs. Lauren Owen English 9 Honors 17 September 2013 The Scarlet Ibis: A Literary Analysis There are multiple literary elements that combine together to create the theme and mood of a story. In the short story, â€Å"The Scarlet Ibis,† the author, James Hurst, demonstrates the use of literary elements and the importance of vital life lessons. The mood in this short story is deeply nostalgic and melancholy. The narrator faces the difficult obstacle of his pride vs. Himself (which is also the critical theme of the story). In the story, Hurst uses the elements of setting, foreshadowing, and symbolism to create a bittersweet, nostalgic memory of the character of Doodle. Various examples of how the setting reveals the mood†¦show more content†¦At the first of the story, Doodle was believed not to even live a couple of days, but he pulled through and worked hard in learning how to walk, row, and do other basic activities. As he kept trying to do more and more work each day, it put more and more stress and pain on his body and his weak heart, he overworked himself, and therefore, his body gave up under all the pressure. When the narrator’s family found the Scarlet Ibis dead, it was noticeable that it had flown from somewhere extensively far away. The Scarlet Ibis and Doodle did the exact same thing – they tried to work themselves more to hopefully accomplish more in the long run, but ultimately ended up killing themselves because their bodies weren’t made strong and proficient, they were made fragile and delicate. In â€Å"The Scarlet Ibis,† the author, James Hurst, clearly defines the valuable message of not letting pride get the best of one. This use of life lessons and other literary elements helped to exemplify the themes demonstrated in the story – setting, foreshadowing, and symbolism.

Minimum Wage Should Be Legal - 1427 Words

There has been a growing desire for minimum wage to be set at $15 an hour. While many of our lowest pay employees will be getting paychecks, workers who have been at businesses longer feel like they’re being undermined. Employees say that it is not fair for a new worker to be earning as much as someone who has been apart of the company for three years. Also, raising minimum wage poses a financial and management challenge for employers. Numerous cities have passed wage increases in the past year, and New York and California recently approved the new wage of $15 an hour. â€Å"The Supreme Court’s decision not to take on a challenge to Seattle’s minimum wage rule removed one of the most significant legal testes of local wage laws.† Seattle has now†¦show more content†¦The Obama administration showed increasing worries in Washington over a rise in intellectual property theft from foreign competitors, such as China. The new rule threatens to shrink com pany-sponsored research, which has become widely popular for high-paying foreign students in recent years. Information regarding defense technology such as munitions, nuclear engineering and satellite technology would be affected by the rule, which is still in the proposal process.Some top U.S. schools do not grant research that restricts participation to foreign citizens because they feel it counters policies on academic freedom and non-discrimination. Universities claim that the rule would offset the balance between national security and academic freedom. In a FBI report they recorded just under a million foreign students at U.S. colleges in the 2014-2015 school year, 31 percent of whom were chinese. The FBI says China is the main culprit for attempted exporting of technology from the United States, including genetically modified corn seed and sensitive military information stored on Boeing computers.

Globalization – the worldwide interdependence of resource flows, product markets, and business competition Technology- technology is an crucial part of everyday business and helped with globalization communication. It has also added flexibility to workplaces through things like, telecommuting. Ethics – set of moral standards of what is â€Å"good† and â€Å"right† in one’s behaviour. Careers – skills should be portable and always of value. Portfolio workers are people who always have the skills needed to readily shift jobs and even careers. Some critical skills include mastering, networking, entrepreneurship, tech-savvy, marketing and passion for renewal Organizations in the new workplace What is an organization? Organizations are collection of people working together to achieve a common purpose. All organizations share a purpose of providing goods or services of value to customers and clients. Organizations as systems: organizations are open systems (they transform resource inputs from the environment into product outputs) that interact with their environments in the continual process of obtaining resource inputs and then transforming them into outputs in the form of finished goods and services for their customers. Organizational performance: When operations add value to the original cost of resource inputs, then 1) a business organization can earn a profit or 2) a non-profit organization can add wealth to society. A way to tell is through productivity which measures the quantity and quality of outputs relative to the cost of inputs. Performance effectiveness is an output measure of task or goal accomplishment. Performance efficiency is an input measure of the resource costs associated with goal accomplishments. Productivity = effective and efficient performance. Changing nature of organizations: Organizational trends and transitions: Renewed belief in human capital: demands of the new economy place premiums on high-involvement and participatory work settings that rally the knowledge, experience, and commitment of all members. Demise of â€Å"command-and-control†: traditional hierarchical structures with â€Å"do as I say† bosses are proving too slow, and costly to do well in today’s competitive environment. Emphasis on teamwork: driven teamwork which pools talents for creative problem solving. Pre-eminence of technology: new opportunities appear with each development in computer and information technology; they continually change the way organizations operate and how people work. Embrace of networking: organizations are networked for intense, real-time communication and coordination, internally among parts and external with partners, contractors, suppliers and customers New workforce expectations: a new generation of workers brings to the workplace less tolerance for hierarchy, more informality, and more attention to performance merit than to status and seniority. Concern for work-life balance: As society increases in complexity, workers are forcing organizations to pay more attention to balance in the often-conflicting demands of work and personal affairs. Focus on speed: everything moves fast, so those who get products to market first have an advantage, work is now expected to be done both well and in a timely manner. Organizational Environment Dynamic forces and the general environment: General environment of organizations consists of all external conditions (economic, legal-political, technological, socio-cultural and natural environmental conditions) that set the context for managerial decision-making. Economic conditions: some of these influence customer spending, resource supplies and investment capital that is crucial for managers to recognize. Legal-Political conditions: monitor changes to understand the trends that can affect the regulation and oversight of businesses. Internet censorship is the deliberate blockage and denial of public access to information posted on the Internet. Technological conditions: technology is only evolving, so you must be up-date with it. Socio-cultural conditions: these conditions take meaning as norms, customers and social values on matters like ethics, human rights, gender roles and lifestyles. All such changes have consequences for how organizations are managed. Natural environment conditions: going â€Å"green† is one of the impacts/changes we have seen in the past few years. Public concern to such matters changes the way organizations will run. Sustainable business is when firms operate in ways that both meet the needs of customers and protect or advance the well-being of our natural environment. Sustainable innovation creates new products and production methods that have reduced environmental impact. Stakeholders and the specific environment: Specific environment (task environment) includes the people and groups with whom an organization interacts and conducts business with. Members of the specific environment are often described as stakeholders, who are the persons, groups and institutions directly affect by an organization. Value creation is the creation of value for and satisfying needs of stakeholders. Competitive Advantage: refers to something that an organization does extremely well, a core competency that clearly sets it apart from competitors and gives it an advantage over them in the marketplace. Competitive advantage is linked with strategic positioning which occurs when an organization does different things or the same things in different ways from its major competitors. Competitive advantage can be achieved in the follow ways: Achieved through costs- finding ways to operate with lower costs and earn profits Through quality- create products/services that are demonstrably and consistently higher quality for customers Through delivery- finding ways to outperform competitors by delivering products and services to customers factored and consistently on time, and to continue to develop timely new products Through flexibility – finding ways to adjust and tailor products and services to fit customer needs in ways that are difficult for one’s competitors to match Environmental Uncertainty: means that there is a lack of complete information regarding what exists and what developments may occur about the environment. There are two dimensions of environmental uncertainty: 1) Degree of complexity or the number of different factors in the environment – an environment is either classified as relatively simple or complex. You read "Gms Ch1" in category "Papers" 2) Rate of change in and among these factors – environment classified as stable or dynamic. High uncertainty environments require firms to have flexibility and adaptability. Organizational effectiveness: is sustainable high performance in using resources to accomplish a mission and objectives. Organizational effectiveness in different viewpoints: Systems resource approach: looks at the input side and defines organizational effectiveness in terms of success in acquiring needed resources from the organization’s environment Internal process approach: looks at the transformation process and defines organizational effectiveness in terms of how efficiently resources are utilized to product goods and services. Goal approach: looks at the output side and defines organizational effectiveness in terms of how to measure achievement of key operating objectives. Strategic constituencies approach: looks at the external environment and defines organizational effectiveness in terms of the organization’s impact on key stakeholders and their interests. Managers in the new workplace What is a manager? A manager is a person who supports, activates, and is responsible for the work of others. Levels of Managers: Top managers guide the performance of an organization as a whole or for one of its major parts (CEO, presidents, and vice presidents). They also create and communicate long-term vision, and ensure that strategies and objectives are consistent with the organization’s purpose and mission. Middle managers report to top managers and oversee the large departments or divisions. Team leaders report to middle managers and supervise non-managerial workers. Top managers guide the performance of an organization as a whole or for one of its major parts (CEO, presidents, and vice presidents). They also create and communicate long-term vision, and ensure that strategies and objectives are consistent with the organization’s purpose and mission. Middle managers report to top managers and oversee the large departments or divisions. Team leaders report to middle managers and supervise non-managerial workers. Type of Managers: Line managers are responsible for work that makes a direct contribution to the organization’s outputs ex: retail manager. Staff managers use special technical expertise to advise and support the efforts of line workers. Functional managers are responsible for one area such as finance, marketing, production, personnel, accounting, or sales. General Managers are responsible for complex, multifunctional units. Managers are sometimes called administrators in public or non-profit organizations. Managerial Performance: Accountability is the requirement to show performance results to a supervisor.

Changing nature of managerial work: Upside-down pyramid is a concept: operating workers are at the top, serving customers, while managers are at the bottom support them. Customers and Clients – ultimate beneficiaries of the organization’s efforts ^Serve^ Operating workers – Do work directly effecting customer/client satisfaction ^Support^ Team leaders and managers- Help operating workers do their jobs and solve problems ^Support^ Top managers – Keep organization’s mission and strategies clear The Management Process Functions of Management: management is the process of planning, organizing, leading, and controlling the use of resources to accomplish performance goals. These steps don’t have to be accomplished in a linear fashion. Planning: the process of setting objectives and determining what should be done to accomplish them. Managers identify desired results and ways to achieve them. Organizing: the process of assigning tasks, allocating resources, and coordinating work activities. Managers can turn plans into actions by defining jobs, assigning personnel, and supporting them with technology and other resources.

Managers can build commitments to a common vision, encourage activities that support goals, and influence others to do their best work on the organization’s behalf. Controlling: the process of measuring work performance, comparing results with objectives, and taking action to ensure desired results and corrective action if it is needed. Managers can maintain active contact with people in the course of their work, gather and interpret reports on performance, and use this information to make constructive changes. Managerial Roles and Activities Managerial Roles: The roles fall into three categories: informational, interpersonal and decisional roles. Informational roles involve the giving, receiving, and analyzing of information.

A manager fulfilling these roles will be a figurehead- the odelling and setting forth key principles and policies; a leader- providing direction and instilling enthusiasm; and a link coordinating with others. Decisional roles involve using information to make decisions to solve problems or address opportunities. A manager fulfilling these roles will be a disturbance handler- dealing with problems and conflicts; a resource allocator- handling budgets and distributing resources; a negotiator- making deals and fo rging agreements; and an entrepreneur- developing new initiatives. Managerial Activities: they are always busy with many things like meetings, problem solving etc. They work long hours, intense work pace, work at fragmented and varied tasks, work with many communication media and accomplish their work largely through interpersonal relationships. Managerial Agendas and Networks: Agenda setting develops action priorities for accomplishing goals and plans. Networking is the process of creating positive relationships with people who can help advance agendas. Networking creates social capital which is a capacity to get things done with support and help of others. Essential Managerial Skills: Learning is a change in behaviour that results from experience. Learning in management is focussed on developing skills and competencies to deal with the complexities of human behaviour and problem solving in organizations.

Malware Detection Of Cloud Computing In Business Field - Samples

Question: Discuss about the Malware Detection Of Cloud Computing In Business Field. Answer: Introduction Identifying malicious software is a complicated issue. There is an ever increasing ecosystem of malicious software along with tools that represents daunting challenge for the network operators and information technology administrator. It is important to develop proper technique for malware detection in a business organization dealing with cloud computing. In this perspective, antivirus software is considered as used tools in order to detect and stop malicious and unwanted software (Klein 2017). The study deals with problem domain and research questions arise in the business. In order to solve the issue, impact of malware detection is analyzed in the present paper. In addition, project requirements analysis as well as specification is discussed in the study. Problem domain and research questions Even though cloud computing provides several advantages in a business organization, there are several issues involved with cloud computing (Dinh et al. 2013). As most of the organizations like to move to adopt cloud computing, it has been the first choice for attacker on internet. There are several types of attacks such as denial of service attacks, side channel attacks, cloud malware injection attack occurred at present day. The malware attack needs adversary creating own malicious service deployment module or virtual machine instance (Yan et al. 2016). It results attacker controlling the cloud system of the business and exploits its privileged accessing the capabilities to the instances of service for attacking instance security domains of the service. Thus, it is important to identify the type of attack and develop appropriate measures that could be helpful to minimize the issues caused for malware in cloud computing (Hatem and El-Khouly 2014). The research questions can be described as followed. What are the processes of attacking in cloud computing by malware in cloud computing of the business organization? How malware detection methods help to minimize the security threats in cloud computing? What are the challenges might be faced for malware detection method implication in the business organization? How the challenges can be overcome? Background and project objective Ferrara, Pistoia and Tripp (2015) stated that it is important to have appropriate malware detection method in order to identify the malware attack and protect cloud computing of the business organization. Malware detection methods are different types. As a network service of malware detection, the capabilities are provided by host-based anti-virus software that can efficiently and effectively provide as in-cloud network service. On the other hand, multi-detection technique has an important role for malicious as well as unwanted software that need to determine (Ko Choo, 2015). Hence, it becomes crucial to identify the appropriate malware detection method that can be helpful for the business organization. Project Requirements Analysis and Specification The project aims to identify the malware detection method suitable and appropriate for the business in order to secure cloud computing (Mollah et al. 2017). Along with this, the project objectives can be listed as followed. To find out the procedures of attacking in cloud computing by malware in cloud computing To identify the malware detection minimizing security threats in cloud computing To analyze the challenges might be faced while implementing malware detection methods in the business organization To recommend solutions for overcoming the issues For the detection of malware in a system there is no requirement of hardware specification. Any system can be used to run the anti-malware softwares. The top five anti-malware softwares in the market has been reviewed below: Bitfender Norton Kaspersky Lab Avira Avast Best Feature Secure Delete 100% Guarantee Safe Banking Gaming Mode DNS Redirecting Loss in Computer Resource 97% 97% 93% 100% 88% False Positives 96% 95% 99% 99% 96% Compatibility Windows 10 Windows 8 Windows 7 Mac Windows 10 Windows 8 Windows 7 Mac Windows 10 Windows 8 Windows 7 Mac Windows 10 Windows 8 Windows 7 Windows 10 Windows 8 Windows 7 Mac Vulnerable Software Detection Yes Yes NA Yes Yes Minimum Number of Licenses 1 1 3 1 1 These are generally known as antivirus softwares. These softwares are able to monitor a computer system for 24x7. They will do periodic scanning of malicious elements in the system and remove them permanently from the system. Choosing of an antivirus is up to the decision of oneself. It is the duty of the owner of the system owner to install a good anti-malware software to safeguard them from harm. These softwares would work similarly on a cloud system. They differ in versions and their capacity to stop the malware from harming the system (Hussein et al. 2017). Conclusion From the discussion, it concludes that it is important for a business organization keeping the business safe and secured. In order to achieve this, business needs to identify appropriate detection technique. Signature based malware detection; Heuristic based malware detection and Specification based detection is the major types of prevention technique through which the business organization can develop malware prevention method. However, several challenges might be faced while implication that requires to eradicate by the professionals of the business organization. References Dinh, H. T., Lee, C., Niyato, D., Wang, P.

Awakening By Kate Chopin Story Essays - The Awakening, Edna, Reisz

Awakening By Kate Chopin Story Throughout Kate Chopin's, The Awakening, numerous scenes of birth and renewal are depicted. Various symbols placed throughout the book show Edna Pontellier's awakenings. For instance, many references are made to oceans and water. It is in the water that Edna has her first rebirth, but it is also the place where she chooses to die. Water symbolizes life, which is the reason that Edna's renewal takes place there, but it also symbolizes darkness and death. Birds, which are featured frequently in the story, symbolize Edna, and in many cases they foreshadow what's to become of her, or they show her renewal of life. The imagery of birds throughout the book is used to symbolize freedom, which is exactly what Edna was trying to achieve from her husband, children, and all the other people that antagonized her. Edna has struggled all summer to learn to swim. She has been coached by the men, women, and children on Grand Isle. Swimming provides Edna with strength and joy, and yet makes her feel just like a child. "But that night she was like the little tottering, stumbling, clutching child, who of a sudden realizes its powers, and walks for the first time alone, boldly and with overconfidence. She could have shouted for joy. She did shout for joy, as with a sweeping stroke or two she lifted her body to the surface of the water" (47). This passage marks Edna's rebirth, or renewal. Here she is described just like a child learning to walk, as she swims for her first time alone. This scene also foreshadows the ending, for here, in the ocean, is where Edna's first rebirth occurs, and in this same place she will take her life. Birds are also major symbolic images in the story. Flight, which is associated with birds, acts as a stand-in for awakening. The ability to spread your wings and fly is a symbolic theme that occurs often in the novel. Mademoiselle Reisz tells Edna "the bird that would soar above the level plain of tradition and prejudice must have strong wings" (138). She uses birds to forecast Edna's future and evaluate Edna's strength. In order to soar like a bird, Edna must be strong, but Mademoiselle Reisz realizes that Edna is weak. Reisz says, "it is a sad spectacle to see the weaklings bruised, exhausted, fluttering back to earth" (138). Mademoiselle Reisz understands that Edna is not like herself and cannot fight society. Later, when Edna realizes the hopelessness of her situation, birds, once again, symbolically foreshadow her fate. Upon reaching the beach on her final walk, Edna looks around and sees: "A bird with a broken wing was beating the air above, reeling, fluttering, circling disabled down, down to the water" (189). This bird is the final omen that reflects Mademoiselle Reisz's words: "it is sad to see the weaklings bruised, exhausted, fluttering back to earth" (138). The bird, disabled and weakened because of its broken wing, falls back to earth and suffers defeat. Edna soon does the same when she kills herself because she does not have "the courageous soul that dares and defies" (106). This bird also symbolizes Edna's final failure. It is a "weakling" according to Mademoiselle Reisz because it lacks strong wings that a bird must have in order to "soar above the level plain of tradition and prejudice" (138). In the same way, Edna lacks the strength to overcome tradition. Therefore, she, too, is a "weakling" and a failure. Edna is awakened in this death scene because she finally realizes that she can't overcome society's expectations of her. Thus, Edna felt, killing herself was the only way to escape what was demanded of her. Throughout the book, Edna is merely expected to run the house, care for the children and do her best to please her husband, Leonce Pontellier, not unlike a bird in a cage. Nevertheless, she finds the role unbearable. She cannot give her life, her identity, to others. Edna is willing to live her life for herself and only herself. By committing suicide, Edna escapes from the clutches of her husband and children. Therefore, Edna's death is considered a spiritual defeat. She realized she could not last in a world where she had to live up to society's expectations of simply being a responsible mother and wife. Just as the injured bird fell to the ground, Edna fell because she lacked the strength to overcome all the obstacles in her way.

The Chemistry Behind Sparkler Fireworks

The Chemistry Behind Sparkler Fireworks All fireworks are not created equal! For example, there is a difference between a firecracker and a sparkler. The goal of a firecracker is to create a controlled explosion. A sparkler, on the other hand, burns over a long period of time (up to a minute) and produces a brilliant shower of sparks. Sometimes sparklers are called snowballs in reference to the ball of sparks that surrounds the burning part of the sparkler. Sparkler Chemistry A sparkler consists of several substances: An oxidizerA fuelIron, steel, aluminum, or other metal powderA combustible binder In addition to these components, colorants, and compounds to moderate the chemical reaction also may be added. Often, firework fuel is charcoal and sulfur. Sparklers simply may use the binder as the fuel. The binder is usually sugar, starch, or shellac. Potassium nitrate or potassium chlorate may be used as oxidizers. Metals are used to create the sparks. Sparkler formulae may be quite simple. For example, a sparkler may consist only of potassium perchlorate, titanium or aluminum, and dextrin. Now that youve seen the composition of a sparkler, lets consider how these chemicals react with each other: Oxidizers Oxidizers produce oxygen to burn the mixture. Oxidizers are usually nitrates, chlorates, or perchlorates. Nitrates are made up of a metal ion and a nitrate ion. Nitrates give up 1/3 of their oxygen to yield nitrites and oxygen. The resulting equation for potassium nitrate looks like this: 2 KNO3(solid) → 2 KNO2(solid) O2(gas) Chlorates are made up of a metal ion and the chlorate ion. Chlorates give up all of their oxygen, causing a more spectacular reaction. However, this also means they are explosive. An example of potassium chlorate yielding its oxygen would look like this: 2 KClO3(solid) → 2 KCl(solid) 3 O2(gas) Perchlorates have more oxygen in them but are less likely to explode as a result of an impact than are chlorates. Potassium perchlorate yields its oxygen in this reaction: KClO4(solid) → KCl(solid) 2 O2(gas) Reducing Agents The reducing agents are the fuel used to burn the oxygen produced by the oxidizers. This combustion produces hot gas. Examples of reducing agents are sulfur and charcoal, which react with the oxygen to form sulfur dioxide (SO2) and carbon dioxide (CO2), respectively. Regulators Two reducing agents may be combined to accelerate or slow the reaction. Also, metals affect the speed of the reaction. Finer metal powders react more quickly than coarse powders or flakes. Other substances, such as cornmeal, also may be added to regulate the reaction. Binders Binders hold the mixture together. For a sparkler, common binders are dextrin (a sugar) dampened by water or a shellac compound dampened by alcohol. The binder can serve as a reducing agent and as a reaction moderator. How Does a Sparkler Work? Lets put it all together: A sparkler consists of a chemical mixture that is molded onto a rigid stick or wire. These chemicals often are mixed with water to form a slurry that can be coated on a wire (by dipping) or poured into a tube. Once the mixture dries, you have a sparkler. Aluminum, iron, steel, zinc or magnesium dust or flakes may be used to create the bright, shimmering sparks. The metal flakes heat up until they are incandescent and shine brightly or, at a high enough temperature, actually burn. A variety of chemicals can be added to create colors. The fuel and oxidizer are proportioned, along with the other chemicals, so that the sparkler burns slowly rather than exploding like a firecracker. Once one end of the sparkler is ignited, it burns progressively to the other end. In theory, the end of the stick or wire is suitable to support it while burning. Important Sparkler Reminders Obviously, sparks cascading off of a burning stick present a fire and burn hazard. Less obviously, sparklers contain one or more metals to create the sparks and any colors, so they can present a health hazard. For example, they should not be burned on cakes as candles or otherwise used in a manner which could lead to consumption of the ash. So use sparklers safely and have fun!

How math is used in firefighting Research Paper Example | Topics and Well Written Essays - 500 words

How math is used in firefighting - Research Paper Example According to the website XP Math, there are at least 20 Math topics that fire fighters need to know. Some of these fall under the realms of Basic Math/Algebra, First Year Algebra (which includes the use of formula), Geometry and Computer (T.L. Hui). Algebra is used in fire fighting hydraulics specifically in calculating the flow rates and capacities (WikiAnswers.com). There are fire fighting terms such as total engine pressure and nozzle pressure. â€Å"Total Engine Pressure is the amount of pressure (psi) that the fire pump (on the truck) is sending through the hose line. The engineer calculates the total engine pressure to adjust for changes in elevation pressure so that the nozzle can receive the correct amount of water pressure (in psi)† (San Bernardino Professional Fire Fighters). There is also the concept of nozzle pressure. It stands for â€Å"the amount of pressure that the nozzle requires to deliver the proper amount of water to the fire† (San Bernardino Professional Fire Fighters). To calculate the accuracy of this, mathematicians have created the nozzle pressure formula, given as: Where n – nozzle pressure in psi, t – total engine pressure and h – change in elevation. This formula â€Å"can be used to find out what the nozzle pressure is for a given height with a specific total engine pressure† (San Bernardino Professional Fire Fighters). There are other applications of math in fire fighting. Math is being used in perimeter, fractions, ratios, percentage and area of burns. The perimeter of burn is â€Å"the distance around the fire or along the hand line† and it is â€Å"determined by adding the lengths of the various lines that enclose the black area of a fire† (SEM and Missoula Fire Science Lab). There are also hydraulic concepts regarding the use of water in wildland firefighting. â€Å"These include determining
