Victorian Era: Society, Politics, and Poetry

Classified in Social sciences

Written at on English with a size of 4.29 KB.

The Victorian Age

Social and Historical Context

The Victorian age covers a wide period and was very productive, literarily speaking. We find the so-called professional writing: writers devoted their lives to writing. Literature became a profession. It constituted an outstanding moment for the development of non-fictional works. Poetry was cultivated, but the novel was the preferred genre.

Queen Victoria ruled Britain from 1837 to 1901. She brought important political and economic development to her country. It was the age of Colonialism, and a new philosophy was introduced. We are speaking about expansion and development. Queen Victoria was very young when she became queen. She was born in 1819 and died in 1901. She was in her teens when she became...

Understanding Landslides: Causes and Impacts

Classified in Geology

Written at on English with a size of 2.54 KB.

Hello, we are going to talk about landslides. For us, this is really a massive natural disaster because it has a strong impact on all aspects, like the environment, the economy, and security. It is important to know about them because, basically, they can happen anywhere in the world. But first of all, what is a landslide?

Understanding the Causes of Landslides

It's important to understand the causes of this natural disaster because often people think that natural disasters are caused by supernatural forces. For example, in Mexico, some people believe that earthquakes happen in the month of September. Similarly, with landslides, some people think they are caused by a punishment from God or because Mother Nature is angry, but this is completely...

Business Meeting Skills, Customer Relations, and Advantage

Unit 4: Chairing Meetings

Chairing a meeting means ensuring that a meeting achieves its aims. The meeting should have been called for a specific purpose, and all discussion at the meeting must be to this end. These are some of the skills required:

Impartiality

A chairperson should ensure that all participants have an opportunity to express their point of view.

Assertiveness

Ensuring that everyone gets a hearing will almost certainly involve stopping someone from dominating the proceedings. The more contentious the issue, the more likely you are to require firmness, although phrases like “I think we should hear from Ms. Smith on this” should be sufficient in most cases. Once you provide this opening, however, you need to ensure: no interruptions... Continue reading "Business Meeting Skills, Customer Relations, and Advantage" »

Understanding Simple Random Sampling in Statistics

Classified in Mathematics

Written at on English with a size of 652 bytes.

Simple Random Sample

A sample designed in such a way as to ensure that (1) every member of a population has an equal chance of being included in the sample, and (2) every sample of size n has the same chance of occurring.

Selecting Elements

Subjects are selected at fixed sampling intervals by selecting every kth element thereafter. The interval between selections is determined by the ratio of the population size to the sample size (N/n). For example, if the population size is N=1,000 and a sample size of n=100 is desired, then the sampling interval is 1,000/100 = 10, so every 10th person is selected into the sample.

Travel Agencies

Definition and Functions

A travel agency is a business that sells travel services like tours, cruises, transportation, accommodation, meals, and sightseeing to the public. It utilizes management practices such as division of labor and hierarchical authority to achieve its objectives, including customer satisfaction and profit generation. Acting as a representative of airlines, hotels, tour companies, and cruise lines, travel agencies cater to both leisure and business travelers.

Expert Advice and Packages

Travel agents provide valuable advice to tourists regarding climate, local culture, customs, and other essential information. They also play a key role in selling package holidays, drawing inspiration from pioneers like Thomas... Continue reading "The Role of Travel Agencies and Tour Operators in the Tourism Industry" »

Elastic Fibers and Gas Exchange in the Respiratory System

Classified in Biology

Written at on English with a size of 2.98 KB.

Elastic Fibers

Elastic fibers maintain the position of alveoli and bronchioles. When fibers recoil during exhalation, they reduce the size of alveoli and push air out.

Pneumocyte Type I

Pneumocyte type I cells are squamous epithelial cells that are unusually thin, providing an ideal site for gas diffusion.

Pneumocyte Type II

Pneumocyte type II cells are scattered among the squamous cells and produce surfactant.

Breathing

Deep breathing, also known as diaphragmatic breathing, involves the contraction of the diaphragm to change the volume of the lungs, allowing air to be exhaled passively. Shallow breathing, or costal breathing, occurs when the rib cage alters its shape, changing the thoracic volume.

Dalton's Law

Dalton's Law states that the partial pressure... Continue reading "Elastic Fibers and Gas Exchange in the Respiratory System" »
