A direct quotation in the text:
"On 28 October, Robert Willner held a press conference at a North Carolina hotel, during which he jabbed his finger with a bloody needle he had just stuck into a man who said he was infected with HIV."¹ This demonstration was meant to prove Peter Duesberg's alternate theories that HIV did not exist, and was to give rise to a dire period in South Africa's health policies...

Paraphrasing the same text used in the example above:
In 1994 a man by the name of Robert Willner held a dramatic press conference. He pricked his finger with a blood contaminated injection needle, which he had previously withdrawn from another man. It was claimed that this second man was infected with HIV (1). This demonstration was meant to prove Peter Duesberg's alternate theories that HIV did not exist, and was to give rise to a dire period in South Africa's health policies ...

There are two dominant information literacy models. In one of these models (Bundy, 2004), information literacy is seen as a list of skills, attributes and knowledge. The second model depicts information literacy as a series of stages (Kuhlthau, 1993). Both models are problematic, as they "portray information literacy as a generic activity, seemingly unrelated to topic and content" (Lupton, 2008, p.400).
