Information Display and Verification

When performing functions that require verbal transmission or repetition, the appropriate information must be displayed and used to match against the verbal communication in order to verify accuracy. Examples include transmission of mandatory directives, reporting clear of authority limits, and restoring main track switches through the POS process. When information is displayed on the workstation or a form is accessed, advise readiness to the field employee and restate the authority number involved. If the field employee begins to state information without the appropriate information screen displayed: Do not accept the information.

What Is a Creole Language?

A creole language, or simply a creole, is a stable natural language that has developed from a pidgin, i.e., a simplified version of a language. Creoles differ from pidgins because creoles have been nativized by children as their primary language. As a result, they have features of natural languages that are normally missing from pidgins, which are not anyone's first language.

The Etymology of the Word 'Creole'

The English term creole comes from French créole, which is cognate with the Spanish term criollo and Portuguese crioulo. All descend from the verb criar ('to breed' or 'to raise'), which comes from the Latin creare ('to produce, create').^[15] The specific sense of the term was coined in the 16th and 17th centuries...

The Cold War: A Summary

The Cold War was a long period of tension between the democracies of the Western World and the communist countries of Eastern Europe. The West was led by the United States, and Eastern Europe was led by the Soviet Union. These two countries became known as superpowers. Although the two superpowers never officially declared war on each other, they fought indirectly in proxy wars, the arms race, and the space race.

Key Events and Turning Points

The Yalta Conference

At Yalta, the future of Poland was discussed. Stalin wanted control of Poland, but the U.S. and U.K. were strongly against it. Britain pointed out that they had entered the war in defense of Poland and could not accept anything but free elections in an independent...

Key Social Topics in Spain

Right to Education

When we talk about the right education, we refer to the right to a school education for children. In Spain, education is compulsory until sixteen years of age. In underdeveloped countries, a great majority of children do not have this right, and most organizations work for this cause. From my point of view, all people should have this right and be able to make use of it. Rich countries, for example France or the USA, should provide financial support for this cause.

Young People and Family Bonds

In Spain, families and friends are important and very close. A tradition is to gather the entire family on Sundays for lunch and spend the day together. From my experience, my family is very small but we are... Continue reading "Spanish Social Issues: Education, Family, and Consumerism" »

Understanding Map Generalization

What is Cartographic Generalization?

Reality has far too much information to be conveyed on a single two-dimensional map. Map generalization is the process of selecting and simplifying map features appropriate to the map's scale and purpose.

Key Techniques in Map Generalization

• Selection: Choosing only relevant line, point, and area features to be mapped. This decision is based on the map's intended use.
• Simplification: Reduction of unnecessary detail, often involving reducing the number of vertices (corners) in a polygon shape or line.
• Smoothing: Similar to simplification, this technique smooths out abruptly joined lines, improving aesthetic quality.
• Displacement: Shifting overlapping features slightly so that all

The Problem of Induction

Inductive reasoning goes from the particular to the general, from the observed to the unobserved.

Practical Problems

• How many observations are enough?
• Even well-confirmed hypotheses can later turn out to be wrong.
• Most scientists believe they really are discovering the fundamental laws of the universe, yet we have observed only a minute fraction of the universe.

Theoretical Problem

Science is supposed to be an empirical discipline that makes no claims beyond what is observed. However, this would stop any hypothesis from going from the particular to the general.

Key Thinkers and Scientific Method

Karl Popper (1902-94)

Rejected theories that tried to explain everything.

Alfred Adler (1870-1937)

Believed that human beings are dominated... Continue reading "The Problem of Induction in Science" »

Key Concepts in Engineering Economics

Engineering Economics is the science dealing with quantitative analysis techniques for selecting the most preferable alternative from several technically viable options.

Fundamental Principles

Four fundamental principles must be applied in all engineering economic decisions:

• The time value of money
• Differential (or incremental) cost and revenue
• Marginal cost and revenue
• The trade-off between risk and reward

Core Terminology Explained

Ethics

Heritage Tourism Management

Definition and Management Plan

Management is a process businesses undertake to achieve organizational performance. In order to achieve this goal, a plan called a ‘management plan’ has to be proposed. However, even the best management plan has to have a legal framework and certain tools must exist:

• Administrative
• Financial
• Conservation
• Social

Setting short and long-term strategies for the protection and enhancement of the cultural heritage leads to specific plans and elements, among which should be:

• Boundary Survey and Description
• Land Use Plan
• Conservation
• Utilities and Services Plan
• Community Development Plan
• Tourism Plan

Such a plan of action would help to preserve the sites for future generations. It would also help to... Continue reading "Effective Heritage Tourism Management: Strategies & Planning" »

What Are Values?

Values define what is worthwhile, beneficial, important, useful, and desirable for people. They influence feelings, attitudes, and behaviors. Values encompass various types, including economical, aesthetical, and moral/ethical values.

Values and Facts

Ethical questions are challenging because value judgments (e.g., good, bad, beautiful, fair) cannot be proven true or false. While facts like "grass is green" or "the earth is round" are provable, concepts like the morality of racism or murder are not.

Different Conceptions of Ethics

1. Situational Ethics

In situational ethics, right and wrong depend on the specific situation. There are no universal moral rules or rights; each case is unique. This approach emphasizes flexible guidelines... Continue reading "Understanding Ethical Values and Frameworks" »
