Prelude to Revolution

In February 1917, a massive demonstration in Petrograd sparked a general strike and barracks riots. The Tsar abdicated, and a provisional government, dominated by bourgeois parties, took power.

The Provisional Government

The provisional government promised to establish a parliamentary democracy but remained committed to the war effort. This hindered promised reforms and exacerbated popular discontent.

Rise of the Soviets

The Soviets, workers' councils, demanded the government's dismissal and withdrawal from the war. The unity that had fueled the revolution began to fracture, creating a duality of power between the provisional government and the Soviets.

The Bolshevik Revolution

On October 25, 1917, the Bolsheviks, supported by... Continue reading "The Russian Revolution: From Tsarist Autocracy to Bolshevik Rule" »

Infectious Diseases: An Overview

Changes to body physiology that disrupt normal body functions and are caused by microorganisms are called infectious diseases. This explanation, established by Louis Pasteur and Robert Koch, is called the germ theory of disease.

Causes of Infectious Diseases

Infectious diseases are caused by various microorganisms, including:

• Viruses
• Bacteria
• Fungi
• Protists
• Parasitic worms

Disease-causing microorganisms are also called pathogens. Koch also developed a series of rules, known as Koch's postulates, that help scientists identify which organism causes a specific disease.

While many microorganisms are symbionts that are either harmless or beneficial, pathogens cause disease by:

• Destroying cells
• Disrupting body functions
• Releasing

Key Motivational Theories

Theory X and Theory Y

• Theory X: Focuses on physiological needs, safety, and security needs.
• Theory Y: Focuses on love (social) needs, esteem needs, and self-actualization needs.

ERG Theory

• Existence Needs: Encompass physiological and physical safety needs.
• Relatedness Needs: Encompass interpersonal safety, love, and esteem needs.
• Growth Needs: Encompass self-actualization and self-esteem needs.

McClelland's Need Theory

Manifest Needs: Learned or acquired needs that are easily perceived.

• Need for Achievement: Encompasses excellence, competition, challenging goals, persistence, and overcoming difficulties. People with a high need for achievement perform better.
• Need for Power: Concerns the desire to influence others, change people

Central Powers

Germany, Austria-Hungary, Turkey, Bulgaria, Italy (only 1 year)

Allies

The war started in Europe but affected other continents due to the colonial expansion.

Causes

The 28 June 1914, Franz Ferdinand (the A-H heir to the throne) was murdered in Sarajevo, Bosnia. With his wife Sophie, by the Serbian nationalist student Gavrilo Princip.

Human Body Anatomy: Head to Toe

Inside the head is the brain, which is responsible for thinking. The top of a person's scalp is covered with hair. Beneath the hairline at the front of the face is the forehead.

Underneath the forehead are the eyes for seeing, the nose for smelling, and the mouth for eating. On the outside of the mouth are the lips, and on the inside of the mouth are the teeth for biting and chewing food, and the tongue for tasting. Food is swallowed down the throat.

At the sides of the face are the cheeks, and at the sides of the head are the ears for hearing. At the bottom of a person's face is the chin. The jaw is located on the inside of the cheeks and chin. The neck is what attaches the head to the upper body.

The Renaissance Period: A Transformation

The modern period, spanning from the fall of the Byzantine Empire in 1453 to the French Revolution in 1789, witnessed significant global changes. Continents were no longer isolated, with trading routes and colonies established worldwide. Scientific advancements and economic growth led to major social transformations.

Religious and Social Shifts

Internal divisions within the Church split Europe into Protestants and Catholics, leading to increased religious intolerance and wars. The end of the Middle Ages saw the rise of the bourgeoisie, a new social class that, along with the nobility and the Church, became patrons of the arts and sciences. Composers and performers gained recognition as true artists for... Continue reading "Renaissance Era: Cultural Shifts, Music, and Social Transformation" »

What is an Audio Mixer?

An audio mixer combines an array of inputs into a few controllable outputs. It features a variety of controls.

The channels are laid out in strips. The signal comes in physically through the back of the device, then passes through that channel's various controls from top to bottom, with the gain or trim at the top and the fader at the bottom.

Step 2: Gain/Trim

The gain knob sets the "input volume." Because of the way a sound signal is composed of several different sounds at different volumes mixed together, the gain will naturally eliminate some of the very quiet signals unless it is set very high.

Using Gain: Gain should be used just like any other control knob: to set the kind of sound you want and its quality. Any gain... Continue reading "Audio Mixer Basics: Understanding Controls and Signal Flow" »

Learner Needs

Learner Needs: When a learner learns a foreign language, he or she has various kinds of needs which influence his/her learning.

• Personal needs: need for praise, need to become more fluent.

• Professional needs: learning English to give presentations.

Approaches to Language Teaching

Approach: Our view of a language or view of how learning a language takes place.

• They involve our beliefs about teaching, language learning, and how we translate all of these into classroom practices.

Presentation, Practice and Production (PPP)

A common teaching sequence:

1. Presentation: of an aspect of language in a context that students are familiar with.

2. Practice: students do an activity to become familiar with it.

3. Production: students will use the language in

Effective Segmentation

MEASURABLE: The size, purchasing power, and profiles of the segments can be measured.

ACCESSIBLE: The market segments can be effectively reached and served.

SUBSTANTIAL: The market segments are large or profitable enough to serve. A segment should be the largest possible homogeneous group worth pursuing with a tailored marketing program.

DIFFERENTIABLE: The segments are conceptually distinguishable and respond differently to different marketing-mix elements and programs.

ACTIONABLE: Effective programs can be designed for attracting and serving the segments.

Important:

The difference delivers a highly valued benefit to target buyers.

Differences to Promote

DISTINCTIVE: Competitors do not offer the difference, or the company can... Continue reading "Principles of Marketing" »
