What Defines Us as Human Beings?

What are the essential characteristics that define us as human beings? We can approach this question by comparing ourselves with other creatures, examining their senses, abilities, and manifestations of animal intelligence.

Comparison with Other Creatures

We must look backward at our distant ancestral past and forward at the development of artificial intelligence (AI).

Key Human Characteristics

• The capacity to communicate, interact, and exchange thoughts or different points of view.
• The ability to subsist by working and creating new social links with people.

We are different from animals, yet fundamentally similar in the drive to subsist and stay alive. However, while animals behave in a wild way, humans are expected... Continue reading "Human Definition, Evolution, and the Nature of Intelligence" »

One of the dynamic gains from trade is the diffusion of technological advance. Can you explain this gain and the impact on domestic companies? 10 points.

The dynamic gains refer to the relationship between trade and economic growth. The economy experiences increases in its stock of productive factors because a technological innovation helps a country's existing stock of factors to become more efficient. This means in our model the PPF has a growth.

The United States has used quotas to protect its domestic sugar industry. What has been the likely impact of these quotas on the world price of sugar (relative to the price that would exist under free trade)? 10 points.

Quotas restrict the amount of foreign competition in the marketplace, so that means... Continue reading "Understanding Trade Dynamics and Policies Impact" »

Levels of Biological Organization

• Atom: The smallest component of chemical elements that make up living things (bioelements), primarily Carbon (C), Oxygen (O), Hydrogen (H), Nitrogen (N), Phosphorus (P), Sulfur (S), Calcium (Ca), Magnesium (Mg), and Sodium (Na).
• Molecule: A group of two or more atoms joined together chemically.
• Organelles: A group of biomolecules that work together to form cell structures, such as membranes, ribosomes, and mitochondria.
• Cell: A group of organelles and structures. A cell is the simplest level of life.
• Tissue: A group of specialized cells that work together to perform a specific function.
• Organ: A group of different tissues that work together to carry out a specific function.
• Organ System: A group of similar or different

1 Inside The larynx there are two flaps of muscle which are called the vocal or folds

vocal cords.

2 The space Between them is known as the glottis.

-wide Glottis /p/ /f/ /s/

- narrow Glottis /h/

-vocal Folds’ vibration

-tigtitly Closed ?  -when we cough

Producing sounds              air---stop the flow of air—move to Articulators—produce release

3 When they Are tightly closed they can be made to produce a glottal stop.

4 When they Are close together and air is passed between them, the resulting vibration is Called voicing or phonation.

5 Three Variables in this vibration that are relevant in speech are: intensity: high/low levels, frequency amount Vibration/regularity, quality whispering/breathy.

Brain & Learning

Theories & Concepts

Sensation and Perception

Sensation: Receiving stimuli.

Perception: Understanding stimuli.

Selective attention: Focusing on a specific aspect of experience.

Selective perception: Recalling only circumstances that confirm our beliefs.

Cognitive Frameworks

Paradigms (Frames): Theoretical frameworks.

Paradigm shift: Change in the overriding theoretical framework.

Neuroplasticity: Brain's capacity to change based on experience.

Functional fixedness: Getting locked into one way of thinking.

Determinism vs. Free Will

Determinism: Belief in being governed by external forces (biological, Freudian, behavioral).

Free will: Belief in being a result of choices made.

• Internal locus of control: Taking responsibility.
• External locus of control: Blaming others.

Self-Talk

Rome was located in the center of Europe and the Mediterranean Sea (good for expansion) and protected by mountains in the north. It was founded by twin brothers: Romulus and Remus in 753 BCE. It was a fusion between Etruscan and native Roman elements. The Roman Republic was a system of government ruled by elected representatives. The Roman Empire conquered the Mediterranean, after fighting three wars: Punic Wars. The decline and fall of the Roman Empire took place between 133-31 BCE. During the Age of Augustus (31-14 BCE) there were provincial reforms, uniform imperial policy was established, and the frontiers were stabilized. There were five good emperors who followed the Pax Romana. The crisis in the third century was caused by military anarchy,...

Wetlands

Wetlands are characterized by standing water or inundated soil and are the only ecosystem protected by law under the Wetlands Protection Act.

Defining Characteristics

• Plants present
• Soil characteristics
• Hydrology

Wetland plants are known as hydrophytes, which possess special adaptations to live in water. While biodiversity is generally low due to a few dominant plant types, productivity is high.

Types of Wetlands

Coastal Wetlands

These are vital as nurseries for fish and invertebrates.

• Salt Marshes: Found in the Temperate Zone; herbaceous plants; primary productivity (PP) = 8000.
• Mangrove Forests: Found in the Tropic Zone; trees are dominant; PP = 3300.

Freshwater Wetlands

These are found along a gradient ranging from permanently flooded to periodically... Continue reading "Understanding Wetland Ecosystems and Classification" »
