Commands to the computer Essay Function keys across the top Letter keys in the main section A numeric keypad on the right Cursor movement and editing keys between the main section and the numeric keypad. The layout of the letters on a keyboard is standard across many countries and is called a QWERTY keyboard. The name comes from the first six keys on the top row of the alphabetic characters. Some keyboards come with added keys for using the Internet and others have an integrated wrist support. Ergonomic keyboards have been developed to reduce the risk of repetitive strain injury to workers who use keyboards for long periods of time. The computers processor scans the keyboard hundreds of times per second to see if a key has been pressed. When a key is pressed, a digital code is sent to the Central Processing Unit (CPU). This digital code is translated into ASCII code (American Standard Code of Information Interchange). For example, pressing the A key produces the binary code 01100001 representing the lower case letter a. Holding down the shift key at the same time produces the binary code 01000001 representing the upper case letter A. Advantages: Most computers have this device attached to it It is a reliable method for data input of text and numbers. A skilled typist can enter data very quickly. Specialist keyboards are available Disadvantages: It is very easy to make mistakes when typing data in It can be very time consuming to enter data using a keyboard, especially if you are not a skilled typist. It is very difficult to enter some data, for example, details of diagrams and pictures. It is very slow to access menus and not flexible when you want to move objects around the screen Difficult for people unable to use keyboards through paralysis or muscular disorder. Mouse A mouse is the most common pointing device that you will come across. It enables you to control the movement and position of the on-screen cursor by moving it around on the desk. Buttons on the mouse let you select options from menus and drag objects around the screen. Pressing a mouse button produces a mouse click. You might have heard the expressions double click, click and drag and drag and drop. Most mice use a small ball located underneath them to calculate the direction that you are moving the mouse in. The movement of the ball causes two rollers to rotate inside the mouse; one records the movement in a north-south direction and the other records the east-west movement. The mouse monitors how far the ball turns and in what direction and sends this information to the computer to move the pointer. Advantages: Ideal for use with desktop computers. Usually supplied with a computer so no additional cost. All computer users tend to be familiar with using them. Disadvantages They need a flat space close to the computer. The mouse cannot easily be used with laptop, notebook or palmtop computers. (These need a tracker ball or a touch sensitive pad called a touch pad). Trackball A tracker ball, is like an upside down mouse with the ball on top. Turning the ball with your hand moves the pointer on the screen. It has buttons like a standard mouse, but requires very little space to operate and is often used in conjunction with computer aided design. You will often find a small tracker ball built into laptop computers in place of the conventional mouse. Advantages Ideal for use where flat space close to the computer is limited. Can be useful with laptops as they can be built into the computer keyboard or clipped on. Disadvantages Not supplied as standard so an additional cost and users have to learn how to use them a joy stick is simalar to the mouse but turns at the sides a joy stick is used to play computer games it turns in 8 dirtion and is used for controlling things like cars advantge there is an idmete feel of dirction due to the movement of the stick disavantges its hard to controlthey can break ealisy This document was downloaded from Coursework.

Medieval Battle Tactics Essay -- History Battles Weapons Essays

Medieval Battle Tactics   Ã‚  Ã‚  Ã‚  Ã‚  Medieval tactics were essential for an attack or siege of a castle. Many tactics and strategies helped develop much-improved version of an attacking artifact, like weapons and sieging machinery. The knights of Medieval England which were the cavalry, improved as the years went by, but never actually had any tactics or strategies. The usual knight would just go out there and fight. The knights were the counter offensive against a small siege, but they were ineffective against a large siege of a castle. A siege was very essential for medieval warfare. Siege was like the most important part of an attack; that is if you’re attacking a castle.   Ã‚  Ã‚  Ã‚  Ã‚  As you know no one inhabited New England back then in the Medieval Ages, so many nations were competing for it. One of them was Rome. Rome inhabited New England first, and as being the first settlers they left some of their customs, which among them was the key to war. The Roman legion composed of a huge amount of infantry and some cavalry was an important factor in Roman War. However, if Rome and England were compared then the cavalry of Rome later developed into the Knight. The well trained infantry of Rome’s legion for attacking and invading now was set to defend in Medieval England as it more compares to the castle. Now that you know some about the origination of the Knight and the castle, let’s get into the tactics used by the land units of Medieval England like the knight and the archers.   Ã‚  Ã‚  Ã‚  Ã‚  The knight, being the cavalry of the castle, and also the last line of defense between invaders and the castle, were inferior to a well trained army of foot soldiers. Usually, it was the knight’s ability and bravery decided the medieval battle. The Medieval Knight was trained from childhood. However, they were never taught any strategies. So, when it came to fighting in the battlefield, they used a guerilla warfare method where they would engage the enemy. This was nothing like the disciplined lines of musket men (soldiers with rifles) of the later British; but rather just went out there and everyone fought on their own like a free hand anything goes melee match. When traveling, the medieval knight traveled in a group, however the group was open to attacks because it was not arranged in a strategic way. Soon the knights, who had superior life, and had an advantage towards a one on ... ...troying the defender’s buildings.   Ã‚  Ã‚  Ã‚  Ã‚  The Trebuchet, on the other hand, was the biggest of all the siege weapons. Trebuchet lives up to its name meaning slinging machine. The trebuchet had a long arm that had a big end so that the end would help it propel when released. The arm was buckled down to one side, while the big end would hang in the air until the buckle was released. At the top of the arm you would find a sling with a rock inside. When the buckle was released there were usually soldiers at the other side with ropes attached to the weight, and helping it propel by pulling the ropes.   Ã‚  Ã‚  Ã‚  Ã‚  England came a long way from just plain foot soldiers with minimal padding, to armored knights and siege weapons. Perhaps it was because Feudalism must have affected the way that the medieval forces were and developed along the medieval era of England. Medieval War and War Tactics played a very important role in medieval life because it helped shape future generations of empires. With out war in the medieval ages of England, they would have probably not been prepared for their future role in war among other countries focusing on conquest and expansion of other parts of the world.

Assess the Corporate Social Responsibility of Telecommunication Industries

Mobile telecommunication industries in this country with time have increasingly played major roles in not only the lives of the people within the community in which they are situated but also in the total economic well being of the country as a whole through their social responsibility activities.The Mobile telecommunication industry in this country has increased tremendously within the past couple of years, and have increasingly played major roles in not only the lives of the people within the community in which they are situated but also in the total economic well being of the country as a whole through their social responsibility activities. The idea of Social Responsibility has developed differently around the world because of different histories, culture and institution. Steiner George 2000) In the past years, the multi-faceted problems made it almost impossible for indigenous industries to undertake social activities in developing countries. However, corporate social responsibi lity (CSR) research has blossomed in this new millennium. This is due to the increasing concern expressed by policy makers and individual bodies about corporate social responsibility and the pressure exerted on organizations to demonstrate high ethical standards.This project is very important because Ghana may need a new code of conduct, laws and regulations and multi-stakeholder agreements and private voluntary initiatives as new businesses are beginning to emerge into our system. Telecommunication industry is a typical example of a fast growing industry within our system. It is therefore imperative that we acknowledge the significance of their corporate contribution to the societies and the nation, for this foresight to be smart and articulate. 1. 2 BACKGROUND STUDYThe precise concept of CSR is understood in different ways, having different representations of the concept relatable to different paradigms and concerns. Aside all the differences pertaining to the nature and content o f CSR, a number of the concepts includes human rights, environmental responsibility, diversity management, sustainability, and philanthropy, meaning that it is a complex area with an interdisciplinary focus. It is generally agreed that CSR involves corporations voluntarily exceeding their legal duties to take account of social, economic and environmental impacts of their operations.For example, the European Commission defines CSR as: â€Å"A concept whereby companies integrate social and environmental concerns in their business operations and in their interactions with their stakeholders on a voluntary basis† (European Multistakeholder Forum on CSR, 2004: 3) Corporate Social Responsibility also relates to those management philosophies, policies, procedure and act that have advancement of social welfare as one of their primary objectives (By Boone and Kurtz 1987) CSR is about how companies manage the business processes to produce an overall positive impact on society.Its conce rn is related to certain aspects of the company’s operations such as the quality of their management – both in terms of people and processes, and the nature of, and quantity of their impact on society in the various areas. The term â€Å"CSR† came in to common use in the early 1970s, after many multinational corporations were formed. The term stakeholder, meaning those on whom an organization's activities have an impact, was used to describe corporate owners beyond shareholders as a result of an influential book by R Freeman in 1984. 2] ISO 26000 is the recognized international standard for CSR Public sector organizations. It is widely accepted that CSR adheres to similar principles but with no formal act of legislation. The UN has developed the Principles for Responsible Investment as guidelines for investing entities. Corporate social responsibility (CSR), also known as corporate responsibility, corporate conscience, corporate citizenship, responsible business , sustainable responsible business (SRB), or corporate social performance,[1] is a form of corporate self-regulation integrated into a business model.Ideally, CSR policy would function as a built-in, self-regulating mechanism whereby business would monitor and ensure its support to law, ethical standards, and international norms. Consequently, business would embrace responsibility for the impact of its activities on the environment, consumers, employees, communities, stakeholders and all other members of the public sphere. Furthermore, CSR-focused businesses would proactively promote the public interest by encouraging community growth and development, and voluntarily eliminating practices that harm the public sphere, regardless of legality.Essentially, CSR is the deliberate inclusion of public interest into corporate decision-making, and the honoring of a triple bottom line: people, planet, profit. Stakeholders are taking an increasing interest in the activity of the company. Most l ook to the outer circle, that is, what the company has actually done, good or bad, in terms of its products and services, in terms of its impact on the environment and on local communities, or in how it treats and develops its workforce.Out of the various stakeholders, it is financial analysts who are predominantly focused – as well as past financial performance – on quality of management as an indicator of likely future performance. Developed countries have worked out a way around ensuring that local and international businesses or companies make contributions towards community development. Sainsbury’s and Tesco for instance are typical examples of companies that have contributed towards every community they operate.The contrast however in Africa is that the key people within the community are just contented to accept a bottle of Scottish Whiskey or Schnapps or local spirit over a businessdeal. Ghana needs to get a grip of how best our laws would work for us if we involve businesses co-operation into helping with our community developments. Understanding how international law works and how it can be used to further both national and international CSR objectives. 1. 3 STATEMENT OF THE PROBLEM The mobile telecommunication industry in this country has increased tremendously and continuously growing at a very high speed over the past ten years.The researcher’s aim is to throw more light on the real impact of this industry on the economy through their social activities.

Raising Awareness And Management Of Mental Health - 925 Words

SCHOOL NURSES: RAISING AWARENESS AND MANAGEMENT OF MENTAL HEALTH IN SCHOOL CHILDREN AGES 7-17YEARS LINDA KALLE STRATFORD UNIVERSITY Abstract The center for disease control describes mental disorders among children as serious changes in the ways children learn, behave, or handle their emotions. (CDC.gov). Mental health is an important part of overall health; it is a public health issue for which teachers, family members, healthcare professionals such as school nurses work closely together to raise awareness, treat and manage these mental health disease conditions. (CDC.gov). Introduction According to the National Institute of health (NIH), mental health is described as our emotional, psychological, and social well-being. Mental health†¦show more content†¦In this paper, we are going to look at how school nurses recognize warning signs early on in school children, measures taken to raise awareness and provide care (through proper education and support) to the school children and their families as well as management of the symptoms of mental health disorders within the school community. (nursingtimes.net). Discussion. Recognizing Mental Health Issues: School age children between the ages of 7 and 17years old fall between 2 stages of development; school age (7-12years) and adolescent (12-17years). With childhood development we see changes in behaviors, cognitive and motor functions. Several day-to-day experiences can affect a child’s behaviors and/or cognitive functions; parents getting a divorce, moving to a new town, getting a new brother/sister, going to a new school etc. (nih.gov). During routine school health assessments, the nurse would recognize the following as more serious warning signs of a mental health problem: when the child is reported to be having problems in more than one setting (at school, at home, with peers etc.), reports of changes in appetite or sleep, social withdrawal or fear of things he or she was not afraid of before, returning to behaviors more common in younger children, such as bedwetting, signs of self-destructive behavior, such as head-banging, reports of re peated thoughts of death etc. (nih.gov). Once recognized, the
