Interaction Strategies:

• Taking the Floor: Can ask for attention.
• Co-operating: Can indicate when they are following.
• Asking for Clarification: Can say “Repeat, please”, can say “Sorry, I don’t understand”, and can ask for clarification about key words or phrases.

Example: Talk about your favorite animal with your partner (spoken interaction).

Reception Strategies:

• Grasp the overall meaning (gist).
• Extract specific information.
• Predict.
• Guess the meaning of unknown words.

Example: (CD) Listen and tick the four animals.

Production Strategies:

• Planning: Can rehearse what’s going to be said.
• Can plan silently what’s going to be written.
• Compensating:
  • Can identify what he/she means by pointing.
  • Can use gestures to clarify what he/she wants to say.

The Iberian Pig

The Iberian pig has dark skin with a sparse coat, a pointed snout, and long, slender legs. The genetic trait of this breed is its ability to store fat in muscle tissue, the key to the unmistakable flavor and texture of Iberian hams.

Grazing in the Dehesa

Here, pastures are in fact open woodlands of holm oaks and cork oaks. A traditional, well-balanced diet that is essential to the quality of its meat. The dehesa pastureland is one of the best-preserved ecosystems in Europe, where Iberian pigs breed side by side with wild species, such as rabbits, lizards, or imperial eagles.

Forest Exploitation

Advantages

• The production of wood (to create houses).
• The production of paper (to write).
• The production of furniture.
• Cork
• Resin

Disadvantages

• Forests

Angular Kinetics

Center of Mass

Point around which mass or weight is considered to be concentrated.

Determining COG

• Balance method
• Suspension method
• MRI reconstruction
• Segmental

Segmental Limitation

• Based on Caucasian male cadavers
• Completed in 1930s
• Based on segments being truncated cones

Mechanical Stability

Ability to maintain vertical projection of CG within base of support.

Ways to Increase MS

• Increase mass
• Increase friction between body and surface
• Increased size of base support

Angular Inertia

Property of an object to resist changes in its angular motion.

Factors Influence

Radius has larger influence than mass.

Center of Mass

Point where gravitational force is applied balance

Radius of Gyration

Point where mass can conceptually be concentrated such that it does... Continue reading "Angular Kinetics and Biomechanics" »
