Organic photovoltaic cells promise cheap, flexible and scalable solar energy. Whereas light directly generates free charges in silicon photovoltaic cells, bound electron and hole pairs known as excitons are understood to be the primary excitations in

The optical and electronic properties of π-conjugated polymers in organic electronic devices depend on their intra- and interchain interactions, dictated by the internal arrangement of the polymer chains in an amorphous or semicrystalline aggregated

Alcohol is a contributing factor in many crimes, yet little is known of its effects on eyewitness memory and face identification. Some authors suggest that intoxication impairs attention and memory, particularly for peripheral scene information, but

This study tests the claim that alcohol intoxication narrows the focus of visual attention on to the more salient features of a visual scene. A group of alcohol intoxicated and sober participants had their eye movements recorded as they encoded a pho

Items which discriminate between Ss on the basis of specific background experiences are, as intelligence test items, undesirable. Yet items thus biased and unfair still appear in current tests: (a) subtly ambiguous items which are biased in favour of

It is argued in an earlier paper (Campbell, 1963) that items where many potentially-appropriate solutions initially present themselves are a matter for concern. Series items are a case in point. Various rules of construction may present themselves fo

Studies of factors determining the answers given to test items have neglected the solution procedures whereby the answers are obtained. Right answers can be given for wrong reasons, and the answers themselves give no indication of this. Children 8.5

A study was undertaken to determine the effects of incorporating supraminimal data, i.e. data over and above those logically sufficient for solution, into code items whose solution requires the use of ‘indirect’ procedures involving the identific
