Октомври е месецът, в които всеки организъм започва да трупа повече телесна мазнина и да се подготвя за зимата. Ето защо сега е времето да започнем активно да спортуваме, за да сме тонизирани и здрави през цялата зима. 2. Къде и какво е най-подходящо да спортувате през зимните месеци? 3.

Кардио уред – велоергометър, кростренажор или бягаща пътека 7. За мнозина това са уреди, които са напълно достатъчни за цялостна тренировка, но това не винаги е така.

...1. Psychological Egoism All forms of egoism require explication of “self-interest” (or “welfare” or “well-being”). There are two main theories. Preference or desire accounts identify self-interest with the satisfaction of one's desires. Often, and most plausibly, these desires are restricted to self-regarding desires. What makes a desire self-regarding is controversial, but there are clear cases and counter-cases: a desire for my own pleasure is self-regarding; a desire for the welfare of others is not. Objective accounts identify self-interest with the possession of states (such as virtue or knowledge) that are valued independently of whether they are desired. Hedonism, which identifies self-interest with pleasure, is either a preference or an objective account, according to whether what counts as pleasure is determined by one's desires. Psychological egoism claims that each person has but one ultimate aim: her own welfare. This allows for action that fails to maximize perceived self-interest, but rules out the sort of behavior psychological egoists like to target — such as altruistic behavior or motivation by thoughts of duty alone. It allows for weakness of will, since in weakness of will cases I am still aiming at my own welfare; I am weak in that I do not act as I aim. And it allows for aiming at things other than one's welfare, such as helping others, where these things are a means to one's welfare. Psychological egoism is supported by our frequent observation of...

...Computerized Grading System ( Chapter 1 & 3 ) 1. 1. Computerized Grading System for Metropolitan Academy of Manila Christelle Joy Barreno, Amanda Arevalo, Anderson Emmanuel Abundo, and Chriselle Laput 2. 2. Page 2 1.0Introduction People nowadays are living in an information age dependent upon digital information. Digital information is electronic information, the result of computer processing. Every type of job relies upon getting information, using it, managing it, and relaying information to others. Computers enable the efficient processing and storage of information. A grading system plays a key role in the management system of any school. But, such systems do not often relate expectations, outcomes, and performance. As each student desires to achieve a good score for each assignment, exam, project and/or report, the whole process adds heavy workload for teachers in order to make their evaluation fair, comprehensive, and accurate. From the faculty perspective, these are necessary to avoid disagreement from students and parents. A computerized grading system is a highly desirable addition to the educational tool-kit, particularly when it can provide less effort and a more effective and timely outcome. Grading systems are designed to provide incentives for achievement and assist in identifying problem areas of a student. It is the most commonly used means of analyzing student performance, talents and skills. Students’ grades are vital information needed in advancing...

...A Clockwork Orange (UK Version) Anthony Burgess Introduction A Clockwork Orange I first published the novella A Clockwork Orange in 1962, which ought to be far enough in the past for it to be erased from the world's literary memory. It refuses to be erased, however, and for this the film version of the book made by Stanley Kubrick may be held chiefly responsible. I should myself be glad to disown it for various reasons, but this is not permitted. I receive mail from students who try to write theses about it or requests from Japanese dramaturges to turn It into a sort of Noh play. It seems likely to survive, while other works of mine that I value more bite the dust. This is not an unusual experience for an artist. Rachmaninoff used to groan because he was known mainly for a Prelude in C Sharp Minor which he wrote as a boy, while the works of his maturity never got into the programmes. Kids cut their pianistic teeth on a Minuet in G which Beethoven composed only so that he could detest it. I have to go on living with A Clockwork Orange, and this means I have a sort of authorial duty to it. I have a very special duty to it in the United States, and I had better now explain what this duty is. Let me put the situation baldly. A Clockwork Orange has never been published entire in America. The book I wrote is divided into three sections of seven chapters each. Take out your pocket calculator and you will find that these add up to a total of twenty-one chapters. 21 is the symbol...
