Moral of Washington Irvings The Legend of Sleepy Hollow Essay
Moral of Washington Irving's The Legend of Sleepy Hollow In Washington Irvingââ¬â¢s short story ââ¬Å"The Legend of Sleepy Hollow,â⬠the conflict between Enlightenment and Romantic ideals is narrativized. Irvingââ¬â¢s story is an exploration of the conflict between these two schools of thought. Irving uses his setting, his characters, and his ââ¬Å"moralâ⬠(or lack thereof) to critique the Enlightenment. At first reading, ââ¬Å"Sleepy Hollowâ⬠may seem no more than a dreamy folk tale. But when read in the context of the emerging resistance to Enlightenment thinking, it reveals itself to be a striking denunciation of the ideals of the Enlightenment. The Age of Enlightenment was characterized by the reign of reason. Enlightenment thinkers believed in the supremacy of reason above all other human faculties, and in the perfectibility of man and therefore society. Scientific understanding and the pursuit of knowledge were key pursuits in this time. Materialism was emphasized as an overt rejection of the superstition of the Middle Ages. The ideals of the Enlightenment were rationality, objectivism, and the ââ¬Å"enlightenedâ⬠society based on pragmatism. In ââ¬Å"The Legend of Sleepy Hollow,â⬠Irving uses all of the tools at his disposal as a storyteller to illustrate his criticism of Enlightenment ideals. First of all, he creates an atmosphere and a setting where reason is at a loss. Also, he uses the character of Ichabod Crane to embody Enlightenment principles, and then has this character become a figure of ridicule. Additionally, Irving uses his conclusion to poke fun at the Enlightenment idea of literature as being necessarily didactic. All of these elements come together to provide a thorough indictment of the Enlightenment. ... ...e. He then has the storyteller himself question the veracity of the story with his final line, ââ¬Å"ââ¬â¢I donââ¬â¢t believe one-half of it myself,ââ¬â¢Ã¢â¬ which scorns not just the importance of a moral, but again questions the importance of truth and verifiability. While Irving may poke fun at the idea of a simplistic moral, a clear maxim that one can easily digest, he nevertheless infuses his work with a message. If any ââ¬Å"moralâ⬠could be taken from ââ¬Å"The Legend of Sleepy Hollow,â⬠it is that there are some places where reason cannot guide us. The possibility of a place where reason and rationality are no longer useful is a direct and sharp critique of the ideals of the Enlightenment. Through his ââ¬Å"tools of the tradeâ⬠as a storyteller, Irving effectively denounces the limits of Enlightenment thinking, and opens the door for the possibilities of Romanticism and the Gothic.

System Security Criteria
Trusted Computer System Evaluation Criteria (TCSEC) is applied in classifying and evaluating the computer security in any given system especially where sensitive information is involved. For that reason any organization such as Medical Credential Company has to initially consider a few factors as well as meet security criteria as provided by TCSEC. There exists four divisions (D,C,B, and A) and C,B, and A are further divided into classes but in the context of this study, only classes C-2 (Controlled Access Protection) and B-3 (Security Domains) will be considered.By choosing Class C-2 means that the company opts for Discretionary Security Protection which is under Division C. class C-2 offers defense of the sensitive information/data ââ¬Ëagainst and detection of user abuse of authority and direct probingââ¬â¢. Besides, class C-2 also protects the system form activities of non-users and users who may not be using malicious programs. Class C-2 employs security controls for all ob jects in the system which may be personal files and/or specific devices.Subsequently, an individual is supposed to identify and authenticate him/her ââ¬âself before login into the system and after using a track record of what he/she has done is kept. Therefore Class C-2 puts emphasis on audit trail for evaluation purposes. For that reason, it calls for a selective method to record all events which have occurred and tools to examine the audit record (DoD, 1985). On the other hand, Class B-3 which falls under Mandatory Security Protection, Division B, puts emphasis on security domains in the system.Systems that conform to Class B-3 criteria enforce what Class C-2 criteria entails, discretionary security policies, and its policy. Therefore, Class B-3 is has more has security features compared to class C-2. Reason being substantial confidence is created that the computer system is protected against misuse techniques for instance human error, direct probing, and abuse of authority by users.In particular Class B-3 protects the system from intentional subversions of the computer security methods hence it is widely employed in addressing defense mechanisms against malicious programs. Besides, a computer system that meets security requirements for Class B3 entails security kernel which implements a reference monitor principle which lacks in Class C-2. Both of these classes entail security requirements -classified under policy, accountability, and assurance- aimed at regulating access to information.Security policy, marking, identification, and accountability specify what control measures that needs to be put in place to regulate access to information. Besides, assurance and continuous protection provides guidelines on how a person can obtain credible assurance that overall security is achieved in a trusted system but security requirements in the two classes differ (DoD, 1985; Nibaldi, 1979). Figure 1.Table of security requirements for classes C2 and B3. Legend: â⠬Å"xâ⬠-no requirement; ââ¬Å"-â⬠class has same requirements as the next lower class; ââ¬Å"Râ⬠-class has extra requirement over the lower classes. NB: Adopted from DoD 5200. 28-STD The security requirements outlined in the above table are functionally-oriented and it is in order for the security manager of the company to consider employing security controls first.Considering the security criteria employed by Class B3, as a security manager in the company, it would be better to seek certification for Class B3.

Dwecks Growth Mindset to Close the Achievement Gap
Teachers often use words of praise to motivate their students. But saying ââ¬Å"Great job!â⬠or ââ¬Å"You must be smart at this!â⬠may not have the positive effect that teachers hope to communicate. Research shows that there are forms of praise that may reinforce a studentââ¬â¢s belief that he or she is either ââ¬Å"smartâ⬠or ââ¬Å"dumbâ⬠. That belief in a fixed or static intelligence may prevent a student from trying or persisting at a task. A student may either think ââ¬Å"If I am already smart, I donââ¬â¢t need to work hard,â⬠or ââ¬Å"If I am dumb, I wonââ¬â¢t be able to learn.â⬠So, how can teachers intentionally change the ways students think about their own intelligence? Teachers can encourage students, even low-performing, high-needs students, to engage and achieve by helping them to develop a growth mindset. Carol Dwecks Growth Mindset Research The concept of a growth mindset was first suggested by Carol Dweck, aà Lewis and Virginia Eaton Professor of Psychology at Stanford University. Her book, Mindset: The New Psychology of Successà (2007) is based on her research with students that suggests that teachers can help develop what is called a growth mindset in order to improve student academic performance. In multiple studies, Dweck noticed the difference in a students performance when they believed that their intelligence was static versus students who believed that their intelligence could be developed. If students believed in a static intelligence, they exhibited such a strong desire to look smart that they tried to avoid challenges. They would give up easily, and they ignored helpful criticism. These students also tended not to expend efforts on tasks they saw as fruitless. Finally, these students felt threatened by the success of other students. In contrast, students who felt that intelligence can be developed exhibited a desire to embrace challenges and to demonstrate persistence. These students accepted helpful criticism and learned from advice. They also were inspired by the success of others. Praising Students Dwecks research saw teachers as agents of change in having students move from fixed to growth mindsets. She advocated that teachers work intentionally to move students from a belief that they are ââ¬Å"smartâ⬠or ââ¬Å"dumbâ⬠to being motivated instead to ââ¬Å"work hardâ⬠and ââ¬Å"show effort. As simple as it sounds, the way teachers praise students can be critical in helping students make this transition.à Before Dweck, for example, standard phrases of praise that teachers might use with their students would sound like, I told you that you were smart, or You are such a good student! With Dwecks research, teachers who want students to develop a growth mindset should praise student efforts using a variety of different phrases or questions. These are suggested phrases or questions that can allow students to feel accomplished at any point in a task or assignment: You kept working and concentratedHow did you do that?You studied and your improvement shows this!What do you plan to do next?Are you pleased with what you did? Teachers can contact parents to provide them information to support a students growth mindset. This communication (report cards, notes home, e-mail, etc.) can give parents a better understanding of the attitudes that students should haveà as they develop a growth mindset. This information can alert a parent to a students curiosity, optimism, persistence, or social intelligence as it relates to academic performance. For example, teachers can update parents using statements such as: Student completed what she began Student tried very hard despite some initial failure Student stayed motivated, even when things didnââ¬â¢t go wellStudent approached new tasks with excitement and energyStudent asked questions that showed he or she had a desire to learnà Student adapted to changing social situations Growth Mindsets and the Achievement Gap Improving academic performance of high needs students is a common goal for schools and districts. The U.S. Department of Education defines high needs students as those who are at risk of educational failure or otherwise in need of special assistance and support. The criteria for high needs (any one or combination of the following) include students who: Are living in povertyAttend high-minority schools (as defined in the Race to the Top application)Are far below grade levelHave left school before receiving a regular high school diplomaAre at risk of not graduating with a diploma on timeAre homelessAre in foster careHave been incarceratedHave disabilitiesAre English learners High-needs students in a school or district are often placed in a demographic subgroup for purposes of comparing their academic performance with those of other students. Standardized tests used by states and districts can measureà the differences in the performance between a high needs subgroup within a school and the statewide average performance or a states highest achieving subgroups, especially in the subject areas of reading/language arts and mathematics. The standardized assessments required by each state are used to evaluate school and district performance. Any difference in the average score between student groups, such as regular education students and high needs students, measured by standardized assessments is used to identify what is called the achievement gap in a school or district. Comparing the data on student performance for regular education and subgroups allows schools and districts a way to determine if they are meeting the needs of all students. In meeting these needs, a targeted strategy of helping students to develop a growth mindsetà may minimize the achievement gap. Growth Mindset in Secondary Schools Starting to develop a students growth mindset early in a students academic career, during pre-school, kindergarten, and the elementary school grades ââ¬â¹can have long-lasting effects. But using the growth mindset approach within the structure of secondary schools (grades 7-12) may be more complicated. Many secondary schools are structured in ways that may isolate students into different academic levels. For already high performing students, many middle and high schools may offerà pre-advanced placement, honors, and advanced placement (AP) courses. There may be internationalà baccalaureate (IB) courses or other early college credit experiences. These offerings may inadvertently contribute to what Dweck discovered in her research, that students have already adopted a fixed mindset ââ¬â the belief that they are either ââ¬Å"smartâ⬠and able to take high-level coursework or they are ââ¬Å"dumbâ⬠and there is no way to change their academic path. There are also some secondary schools that may engage in tracking, a practice that intentionally separates students by academic ability. In tracking students may be separated in all subjects or in a few classes using classifications such as above average, normal, or below average. High needs students may fall disproportionately in the lower ability classes. To counter the effects of tracking, teachers can try employing growth mindset strategies to motivate all students, including high needs students, to take on challenges and persist in what may seem difficult tasks. Moving students from a belief in the limits of intelligence can counter the argument for tracking by increasing academic achievement for all students, including high needs subgroups.à Manipulating Ideas on Intelligence Teachers who encourage students to take academic risks may find themselves listening to students more as students express their frustrations and their successes in meeting academic challenges. Questions such as Tell me about it or Show me more and Letââ¬â¢s see what you did can be used to encourage students to see efforts as a path to achievement and also give them a sense of control.à Developing a growth mindset can happen at any grade level, as Dweckââ¬â¢s research has shown that student ideas about intelligence can be manipulated in schools by educators in order to have a positive impact on academic achievement.
