11.2 Note taking

Different ways of note taking include:

  1. Re-writing:

    Here, the rewording of main parts in a course or article is undertaken. The advantage of this method is that you have thought about course concepts and ideas, and put them into your own words. Here you are summarising points and trying to do this concisely. This does not mean copying directly from the text (unless it is a short quotation you have referenced and chosen to illustrate a point).

2.7 Reflecting on explanations of ‘abnormal’ development: the case of dyslexia

We can draw the following general conclusions about cognitive and biological explanations of abnormality from the material presented above.

  • Both cognitive and biological accounts of dyslexia are offered as theories which explain the behavioural difficulties that are observed. While some theories may dominate accounts of a given condition (e.g. the phonological deficit hypothesis), and may result in influencing the nature of interventions, they are stil

8.2 The NOT operation

The NOT operation (note that, as with all logic operators, NOT is always written in capital letters) acts bit by bit on a single binary word according the following rules:

NOT 0 = 1

NOT 1 = 0

In other words, all the 1s in the word are changed to 0s and all the 0s are changed to 1s. Hence, for example,

NOT 1101 1011 = 0010 0100

As you saw earlier, the term complement or 1's complement is sometimes used for the result of the NOT operation. In f

4.2 Levels of explanation

The distinction between the natural and the social is not the only significant one. Even the social orientation in constructions of social problems is complicated by different sorts of emphasis. The growth of social science since the late nineteenth century has ensured that a variety of competing theories, disciplines and perspectives are available to us in our attempt to make sense of social problems. Such theories have made their way into the realm of everyday or common-sense constructions

Poly (lactic-co-glycolic acid) (PLGA) porous scaffold for tissue engineering.
The patients own cells are seeded onto the scaffold and allowed to attach and start producing new bone. The construct is implanted into the defect site, where eventually the polymer will biodegrade and be completely removed, leaving a natural autogenous bone graft. This technique is particularly useful for large defects, or where the host bed is compromised due to disease, although it is still at the research stage. Average Pore Size 350-550 micrometre, porosity estimated at 35-45%.
