Macbeth-gloomy Indeed :: essays research papers

Is the Shakespearean play â€Å"Macbeth† a gloomy play full of darkness and evil? Every way you look at this play it seems very dark and gloomy, whether from a historians point of view, an actors, a casual reader of plays, etc. Three of the main features that add to the dark and evil feel of this play are the atmospheric scenery, the homely and repugnant characters and the homicidal hot-headed back stabbing. The scenery depicted in this play is very gloomy indeed. This gloomy scenery would fit the time period in which this play roughly takes place in. Three very intricate parts of this play happen on a â€Å"moor†(Act1,sc1 & Act1,sc3 & Act4 sc1). In the first act, first scene the witches first meet on a barren , gloomy landscape (Moor). The second time they are on the moor where they begin their shit disturbing. The third time they give Macbeth some more information, about his dark demise. Weather adds to the â€Å"gloominess† of this play. The quote â€Å"Hover through the fog and filthy air† (Act1,sc1) really gives gloomy mental picture. Even the most de-sensitized person can understand how a violent storm is gloomy. This quote, â€Å"As whence the sun’gins ... shipwracking storms and direful thunders break.†(Act1,sc2), tells of one such storm during the battle in the beginning of the play. Storms, battles, that’ll make anyone a â€Å"gloomy Gus†. Lightning is a very gloomy sort of deal because with lightning there is rain and dark clouds and its scary. In this play there are a lot of scenes where lightning and thunder is the weather of choice by Shakespeare (Act1,sc1 & Act1, sc3 & Act3, sc5 & Act4,sc1). The lightning is always present when the witches are involved in a scene. â€Å"Macbeth† comes complete with rather gloomy looking roles like the witches. Banquo explains how horrid these witches look in this quote, â€Å"By each her choppy finger laying upon her skinny lips : you should be women, and yet your beards forbid me to interpret that you are so.†(Act 1,sc3). Women with beards?...... gloomy indeed. And if women with beards weren’t gloomy enough there are old fat ladies in â€Å"Macbeth†. The quote â€Å"...the rump-fed ronyon cries†(Act1,sc3) which tells of a fat old lady. Also, back then no one bathed, and a mixture of fat old ladies (and men) who don’t bathe, would ruin even the most utopian of days. Besides looks, the mysterious power that the witches possess is considered dark.

INTRODUCTION In the present context, managing has become one of the most important areas of human activity because of increasing role of large and complex organisations in the society. Because of their increasing role, the organisations have attracted the attention of both practitioners and academicians to find out the solutions for business problems. Concept Defining the term management precisely is not so simple because the term management is used in a variety of ways. Being a new discipline, it has drawn concepts and principles from a number of disciplines such as economics, sociology, psychology, anthropology, statistics and so on. Each group of contributors has treated management differently. For example, economists have treated management as a factor of production; sociologists have treated it as a class or group of persons; practitioners have treated it as a process comprising different activities. DEFINITION â€Å"Management is the art of getting things done through and with people in formally organized groups† — Koontz â€Å"Management is the art of knowing what you want to do and then seeing that it is done in the best and cheapest way† – F.W. Taylor â€Å"Management is the art of securing maximum results with minimum effort so as to secure maximum prosperity and happiness for both employer and employee and give the public the best possible service† — John Mee. â€Å"Management is the accomplishment of results through the efforts of other people† — Lawrence â€Å"Management is simply the process of decision making and control over the action of human beings for the expressed purpose of attaining predetermined goals† – Stanley V. â€Å"Management is a process involving planning, organizing, staffing, directing and controlling human efforts to achieve stated objectives in an organization.† From the above definitions, the following features are identified:1) Organised Activities: Management is a process of organized activities. Without organized activities, two groups of people cannot be involved in the performance of activities. Where a group of people are involved in working towards a common objective, management comes into existence. 2) Existence of objectives: The existence of objectives is a basic criterion of e very human organization because all organizations are deliberate and purposive creation and, therefore, they should have Introduction to Management some objectives. Without objectives, it becomes difficult to define the direction where organized group of activities would lead to. 3) Relationship among resources: Organised activities meant to achieve common goals are brought about to establish certain relationships about the available resources. Resources include money, machine, material, men and methods. All these resources are made available to those who manage the organization. Managers apply knowledge, experience, principles for getting the desired results. Thus, the essence of management is integration of various organisational resources. 4) Working with and through people: Management involves working with people and getting organisational objectives achieved through them. The idea of working through people is interpreted in terms of assigning and reassigning of activities to subordinates. 5) Decision Making: Management process involves decision making at various levels for getting things done through people. Decision making basically involves selecting the most appropriate alternative out of the several. If there is only one alternative, there is no question of decision making. Nature of Management: – The study and application of management techniques in managing the affairs of the organization have changed its nature over a period of time. The following points will describe the nature of management 1) Multidisciplinary: Management has been developed as a separate discipline, but it draws knowledge and concepts from various disciplines like psychology, sociology, anthropology, economics, statistics, operations research etc.,. Management integrates the idea and concepts taken from these disciplines and presents newer concepts which can be put into practice for managing the organisations 2) Dynamic nature of Principles: Principle is a fundamental truth which esta blishes cause and effect relationships of a function. Based on integration and supported by practical evidences, management has framed certain principles. However, these principles are flexible in nature and change with the changes in the environment in which an organization exists. 3) Relative, Not absolute Principles: Management principles are relative, not absolute, and they should be applied according to the need of the organization. Each organization may be different from others. The difference may exist because of time, place, socio-cultural factors, etc.,. 4) Management: Science or Art: There is a controversy whether management is science or art. An art is personal skill of business affairs. Art is characterized by practical knowledge, personal creativity and skill. The more one practices an art, the more professional one becomes. Management can be considered as an art because it satisfies all these criterion of an art. A science is a systematized body of knowledge of facts. It can establish cause-and-effect relationships among various factors. It involves basic principles, which are capable of universal application. Management can be considered as science because it satisfies all these criterion of a science. Introduction to Management 5) Management as profession: Management has been regarded as a profession by many while many have suggested that it has not achieved the status of a profession. Profession refers to a vocation or a branch of advanced learning such as engineering or medicine. 6) Universality of management: Management is a universal phenomenon. However, management principles are not universally applicable but are to be modified according to the needs of the situation. Importance of Management Management has been important to the daily lives of people and to the organisations. The importance of management may be traces with the following. 1) Effective utilisation of Resources: Management tries to make effective utilisation of various resources. The resources are scarce in nature and to meet the demand of the society, their contribution should be more for the general interests of the society. Management not only decides in which particular alternative a particular resource should be used, but also takes actions to utilize it in that particular alternative in the best way. 2) Development of Resources: Management develops various resources. This is true with human as well as non-human factors. Most of the researchers for resource development are carried on in an organized way and management is involved in these organized activities. 3) It ensures continuity in the organization: Continuity is very important in the organisations. Where there are no proper guidelines for decision making continuity can not be guaranteed. It is quite natural that new people join while some others retire or leave the organization. It is only management that keeps the organization continuing. 4) Integrating various interest groups: In the organized efforts, there are various interest groups and they put pressure over other groups for maximum share in the combined output. For example, in case of a business organization, there are various pressure groups such as shareholders, employees, govt. etc. these interest groups have pressure on an organization. Management has to balance these pressures from various interest groups. 5) Stability in the society: Management provides stability in the society by changing and modifying the resources in accordance with the changing environment of the society. In the modern age, more emphasis is on new inventions for the betterment of human beings. These inventions make old systems and factors mostly obsolete and inefficient. Management provides integration between traditions and new inventions, and safeguards society from the unfavorable impact of these inventions so that continuity in social process is maintained. Functions of Management:To achieve the organisational objectives managers at all levels of organization should perform different functions. A function is a group of similar activities. Introduction to Management The list of management functions varies from author to author with the number of functions varying from three to eight. Writers Henry Fayol Luther Gullick R. Davis Management Functions Planning, Organizing, Commanding, Coordinating, Controlling POSDCORD- Planning, Organising, Staffing, Directing, Coordinating, Reporting, Directing Planning , Organising, Controlling Planning, Organising, Motivating, Coordinating, Controlling Planning, Organising, Staffing, Leading, Controlling Koontz Different authors presented different variations. By combining some of functions, these are broadly grouped into Planning, Organising, Staffing, Directing, and Controlling. 1) Planning: Planning is the conscious determination of future course of action. This involves why an action, what action, how to take action, and when to take action. Thus, planning includes determination of specific objectives, determining projects and programs, setting policies and strategies, setting rules and procedures and prepar ing budgets. 2) Organising: Organising is the process of dividing work into convenient tasks or duties, grouping of such duties in the form of positions, grouping of various positions into departments and sections, assigning duties to individual positions, and delegating authority to each positions so that the work is carried out as planned. It is viewed as a bridge connecting the conceptual idea developed in creating and planning to the specific means for accomplishment these ideas. 3) Staffing: Staffing involves manning the various positions created by the organizing process. It includes preparing inventory of personal available and identifying the sources of people, selecting people, training and developing them, fixing financial compensation, appraising them periodically etc. 4) Directing: when people are available in the organization, they must know what they are expected to do in the organization. Superior managers fulfill this requirement by communicating to subordinates about their expected behavior. Once subordinates are oriented, the superiors have continuous responsibility of guiding and leading them for better work performance and motivating them to work with zeal and enthusiasm. Thus, directing includes communicating, motivating and leading. 5) Controlling: Controlling involves identification of actual results, comparison of actual results with expected results as set by planning process, identification of deviations between the two, if any, and taking of corrective action so that actual results match with expected results. Introduction to Management TAYLOR & SCIENTIFIC MANAGEMENT The concept of scientific management was introduced by Frederick Winslow Taylor in USA in the beginning of 20th century. â€Å"Scientific management is concerned with knowing exactly what you want to do and then see in that they do it in the best and cheapest way† Since Taylor has put the emphasis on solving managerial problems in a scientific way, often, he is called as father of scientific management and his contributions as the principles of scientific management. Taylor carried experiments about how to increase the efficiency of people. On the basis of experiments, he published many papers and books and all his contributions were compiled in his book â€Å"scientific management†. His contributions are divided into two parts. Elements and tools of scientific management Principles of scientific management FEATURES / ELEMENTS AND TOOLS OF SCIENTIFIC MANAGEMENT 1) Separation of planning & doing: Taylor emphasized the separation of planning aspect from actual doing of the work. In other words planning should be left to the supervisor and the worker should concentrate only operational work. 2) Functional foremanship: Taylor introduced the concept of functional foremanship based on specialization of functions. In this system, eight persons are involved to direct the activities of workers. Out of these four persons are concerned with planning viz., route clerk, instruction card clerk, time and cost clerk and disciplinarian. The remaining four persons are concerned with doing aspect of the job, viz., speed boss, inspector, gang boss and maintenance foreman. It is against to the principle of unity of command.

Federal and State Forestry Assistance Programs

There are a variety of U.S. Federal forestry assistance programs available to assist people with their forestry and conservation needs. The following forestry assistance programs, some financial and some technical, are major programs available to the forest landowner in the United States. These programs are designed to help a landowner with the cost of tree planting. Most of these programs are cost-share programs that will pay a percentage of the establishment cost of the trees. You should first study the delivery flow for assistance which starts at the local level. You will have to inquire, sign up, and be approved locally in your specific conservation district. It takes some persistence and you must be prepared to work and cooperate with a bureaucratic process that some people would rather not put up with. Find the nearest National Resource Conservation Service (NRCS) office for assistance. The Farm Bill authorizes billions of dollars in funding for conservation programs. Forestry is certainly a major part. These conservation programs were created to improve natural resources on Americas private lands. Forest owners have used millions of those dollars for the improvement of their forested properties. Listed are the major programs and sources of forestry assistance. However, you need to be aware that there are other sources for assistance on a state and local level. Your local NRCS office will know these and point you in the right direction. Environmental Quality Improvement Program (EQIP) The EQIP program provides technical assistance and cost-share to eligible landowners for forestry practices, such as site preparation and planting of hardwood and pine trees, fencing to keep livestock out of the forest, forest road stabilization, timber stand improvement (TSI), and invasive species control. Priority is given to projects with multiple management practices to be completed over a number of years. Wildlife Habitat Improvement Program (WHIP) The WHIP program provides technical assistance and cost-share to eligible landowners who install wildlife habitat improvement practices on their land. These practices may include tree and shrub planting, prescribed burning, invasive species control, the creation of forest openings, riparian buffer establishment and fencing livestock from the forest. Wetlands Reserve Program (WRP) WRP is a voluntary program that provides technical assistance and financial incentives to restore, protect, and enhance wetlands in exchange for retiring marginal land from agriculture. Landowners that enter into WRP may be paid an easement payment in exchange for enrolling their land. Program emphasis is on restoring wet cropland to bottomland hardwoods. Conservation Reserve Program (CRP) The CRP reduces soil erosion, protects the nations ability to produce food and fiber, reduces sedimentation in streams and lakes, improves water quality, establishes wildlife habitat, and enhances forest and wetland resources. It encourages farmers to convert highly erodible cropland or another environmentally sensitive acreage to vegetative cover. Biomass Crop Assistance Program (BCAP) BCAP provides financial assistance to producers or entities that deliver eligible biomass material to designated biomass conversion facilities for use as heat, power, biobased products or biofuels. Initial assistance will be for the Collection, Harvest, Storage, and Transportation (CHST) costs associated with the delivery of eligible materials.

Early Influences of Freud´s Theory - 1908 Words

Sigmund Freud was born March 6 1856 in Freiberg, Austria. Freud’s birth was somewhat of a controversy. The original announcement was that he was born May 6. The fact is that his mother Amalie was pregnant before she married Freud father Jakob. Freud was the eldest of eight children with Amaile Jokob’s third wife. His father did have two previous marriages. The first marriage he had two other children with Sally Kanner. Amalie had a great impact and influence on her son’s â€Å"Freud† theories. Amaile was much younger than Jokob. History says that she at the time of marriage was about the same age as Jokob’s children from his first marriage. Freud stated his relationship with his mother contributed to his theories. Studying with both Breuer†¦show more content†¦Freud explains that only a trained eye can see what is unsaid. It could be the flicker of the eyes or a habit such as chewing on a pen. Avoidance seems to be a big topic, such as c hanging the subject as a defense mechanism. He explains that many forget progress from session to session do to the emotional trauma. Freud says it is best to sit in a low-lit room out of sight. He did this so the A- patient did not react to his gestures so the patient was not influence by him and B- â€Å"he disliked being stared at for hours†.

The theory of the unconscious mind and theory of personality, contributes toward a better understanding of human personality. Both topics explain why people have that automatic reflex of answering a question with a question or avoiding certain topics in relationship to personalities, cultur e and history.

The Bipolar Enigma By Stephen Ray Harris - 2145 Words

The Bipolar Enigma Stephen Ray Harris Monday, Wednesday, Friday Class (9:00-9:50) Dr. Marc Klippenstine East Central University April 11, 2016 Abstract Currently effecting between 2-4% of the overall population and as one of the leading causes of homelessness, suicide, and hospitalization, bipolar disorder is yet, still one of the most perplexing, as well as the most misunderstood mental disorders out there. With this particular disorder, the complexity arises given one’s predisposition, diversity, and non-specific range of hazards for said disorder; thusly, making a cure, or at best, prevention, difficult, if not impossible, if not for appropriate early intervention. Bipolar not only puts a strain on the economic condition of our country, but on the individual, as well as society as a whole; given, its propensity to bring about financial difficulties, employment difficulties, and poor self-esteem and this is simply three examples, out of quite possible a largely finite numeral of disparities realized within the afflicted, as well as the overall populace. Nothing left of what we deem normal will be left untainted, and with limited governmental funding and a lack of knowledge, mankind’s naà ¯ve, uncaring nature will only bring about less than desirable responses to treatment, medicinally or otherwise; given, the disorder is far more difficult to treat later in life.

Challenges of Teaching Students with Ebd free essay sample

There is much debate and confusion when defining emotional or behavioral disorders (EBD). Until 1997 this category was identified as serious emotional disturbance (SED). With the creation of IDEA in 1997 this category was changed to emotional disturbance (ED). While the federal government still uses ED as there identifying category for this disability, most professionals refer to it as emotional or behavioral disorders (EBD). The identifying names are not the only discrepancies between professionals who work with these children and the government. The federal government defines emotional disturbance as exhibiting characteristics that adversely affects educational performance over a long period of time. More than one characteristic must exist and in a certain degree. These characteristics include: difficulty learning without the present of other factors, unsatisfactory relationships with peers and teachers, inappropriate behaviors and feelings, development of physical symptoms when problems arise (Yell, Meadows, Drasgow, amp; Shriner, 2009). While it is significant that this disorder is defined as a disability by the federal government, thus providing necessary services for these students, it is flawed. There lacks a specific criteria in the length of time and the degree of symptoms. The Mental Health and Special Education Association adapted a definition that is believed to be more functional when identifying students with EBD. They define emotional or behavioral disorders as: â€Å"exhibiting emotional or behavioral responses in school programs are so different from appropriate age, cultural, or ethnic norms that the response adversely affect educational performance† Mental Health and Special Education Coalition, 1990). They note that this impacts academic, social, vocational or personal skills for more than a typical time period as a response to a stressful situation. The behaviors must be demonstrated across two settings, one being school and are not decreased by instruction in the general education classroom (Health and Special Education Coalition, 1990). The definition includes the assertion that this disability can co-exist with others disabilities. The National School Boards Association rejected this definition when presented and continues to use their definition as the tool for classifying children in this disability category. They felt that the definition would significantly increase the number of students identified as having a disability under the ED category (Yell et al, 2009). Controversy remains concerning the definition of ED, which could cause delays or lack of necessary intervention services for many students suffering from EBD. A significant challenge in categorizing students within the EBD category is that they can co-exist with other disabilities. Students can be misclassified as a having another disability or strictly be thought to be deviant. This is due to the fact that many educators are unable to recognize the characteristics of students with EBD. Students with emotional or behavioral disturbances are cognitively in the average or above average range, but consistently perform below normal. These academic deficits can be attributed to teachers not understanding this category of disability and not providing the necessary supports, behavioral strategies, effective instructional strategies or curriculum to meet their needs. Students with EBD may also have a language disorder. Often times when a child is unable to effectively communicate they will use inappropriate behaviors until they learn the necessary communication skills (Yell et al, 2009). Students with EBD are frequently disciplined for school infractions. The first course of action by many schools is to discipline students when they do not follow the rule. While this can be effective, the educator must determine the antecedent of the behavior in order for this to be an effective diversion from committing the same infraction. This can be challenging for a school if they have not had the proper training to perform a functional behavioral analysis. It can also be time consuming to collect the necessary data, but if we want to change undesired behaviors we must learn what the antecedent is and the consequence that may be reinforcing the behavior. If a student is trying to get out of attending school, then disciplining them with a suspension would only reinforce them to perform the same inappropriate behavior again. Another challenge for students with EBD is the ability to interact with peers and adults to create meaningful relationships. Teachers may be unaware that their own social interactions with their students impact their behavior as well. If a teacher focuses on a student’s inappropriate behaviors and only gives attention for those behaviors, the student will be more likely to continue the undesired behavior. A good rule of thumb is to provide three positives for every negative. Another challenge for EBD is the lack of understanding concerning effective strategies to work with this student population. If educators are not in the special education department, they likely do not have much insight on this disability. Educators may view these students as defiant and not provide them with the necessary interventions to help them be successful. Academic interventions should include engaging curriculum with a hands on approach (Yell et al, 2009). Behavioral interventions have proven successful when working with students with EBD. As mentioned previously, performing a functional behavioral analysis can help identify behaviors, their antecedents and consequence. Once this data is collected a positive behavior support plan can be implemented to help the student. Strategies need to be school wide and inside each classroom. Positive behaviors supports to prevent and intervene can help students decrease undesired behaviors and increase preferred behaviors. These strategies must be implemented across all environments to be most effective. When making educational decisions for students with disabilities, no one person should make that decision. It requires the input and collaboration of the entire special education team to ensure that the student’s needs are being met, all factors have been considered, and that the needed strategies are appropriate and can be implemented across all environments. The special education team can consist of: a special educator, a general educator, a vice-principal, a parent, and a school psychologist. Their roles may vary, but all have the same goal in mind, to provide the student with an appropriate education as defined by IDEA. The special educator provides information about how to educate the student. She will work with the student on a regular basis and provide input on the necessary accommodations based on the student’s needs. The special educator can also provide differentiation of curriculum/instruction and create appropriate IEP goals (NICHCY, 2010). The general educator knows the content standards for his grade level and subject. He is able to identify where the student  currently is and where they should be. Based on that information he can provide the team with input on what the next progression should be to get the student to the next level of achievement. He can give insight on what supplementary aids and intervention services are necessary to help the student be successful in his classroom. The general educator will monitor the progress of the student’s IEP goal in his subject area. The vice-principal on the SPED team serves the role of the â€Å"representative of the public agency† responsible for the student’s education as identified under the IDEA (NICHCY, 2010). The vice-principal will supervise to ensure that specially designed instruction is provided to the student. He also has the authority to commit to resources and ensure that the services described in the IEP will be provided to the student. The school psychologist can provide information on the instructional implications of the child’s evaluations. He has done assessments including, the BASC-II, the ABAS, and the DSM-III. Based on assessment results he will give feedback on appropriate instruction to meet the child’s needs (NICHCY, 2010). An important member of the SPED team is the parent. She has insight into the child that is not viewable in the educational setting. She can provide insight as to how the student responds to similar situations at home. parent can also help identify the strengths and weaknesses of her child. She can provide input on IEP goals as to what goals are most important to her and her child. The parent will share information on learning styles, interests, and provide an overview of past learning experiences. The diagnostic team is comprised of professionals who strategically place and provide necessary services for students. When working with students with EBD, this can be a challenge. Thus far the team has concerns with identifying students with EBD, as the federal definition does not provide specifics, as two what length of time a behavior must occur to be considered EBD. Also, the team is concerned that the criteria is not specific enough in how many setting the child should exhibit the behaviors and to what degree. With the lack of information identified under the IDEA 2004 it makes it extremely difficult to identify these students. Several students thought to be EBD, also have other disabilities and the team is not sure if that is the underlying cause for the behaviors. The team wonders if a student falling in the Autism category can also be categorized as EBD. With so much uncertainty the SPED team relies heavily on outside resources, such as developmental and behavioral pediatricians for the diagnosis of EBD. As a team they will make a recommendation, after administering the ABAS and DSM-III if the student is suspected of an EBD diagnosis. Once we know that a child has been identified as EBD, necessary interventions can be placed. The challenges revolve around funding and lack of training. Most general education teachers do not know how to work with this population. Our school is an inclusive school for students with disabilities, including EBD. All students are educated based on academic level, not by disability. The special educator must provide â€Å"on the job† training for general education teachers, while having to provide services for the student as well. This can be a daunting task for the special educator, especially if the general educator doesn’t follow the procedures. A school wide positive behavior support system needs to be implemented and training for all staff needs to be provided. These two things are not implemented as the district has stated that lack of funding is an obstacle for these necessary tools. These issues could be resolved by providing teachers with training on how perform functional behavioral analysis and how to work with students with EBD in general. Teaching educators how to reinforce desired behaviors and not focus on the inappropriate behavior is a simple strategy to increase preferred behaviors. Also, by creating a positive behavior supports school wide and using the tier system we can provide consistent interventions throughout the school. Having a concise definition of emotional disturbances, under IDEA would be helpful in identifying students and providing necessary services. The definition must include a specific duration of time when the behavior falls under a characteristic of EBD. Also, a definitive criterion should be included to help determine the degree of characteristic that facilitates a diagnosis of EBD. The definition also fails to include that a child with EBD may also have another disability or syndrome. This information should be included, so that if a child has a diagnosis of ADHD they are not overlooked if they are exhibiting symptoms of EBD. The newness of this disability contributes to the ambiguity of the definition. The government must be open to changes in our educational laws, as the realm of disabilities is constantly changing.
