In a manufacturing system, time performances are measures of system response speed to external influences. This speed depends on the resource allocation process (materials, equipment, labour) which is driven by finished‐product forecasts. Describes two essential steps, in order to develop a model for evaluating time performances which is able to detect crucial resources. The first step is represented by analysing forecast characteristics; the second step is expressed by a definition of the environment of manufacturing resources. The model, depicted in its structure and in its relationships with the most common business tools, has been tested in a number of manufacturing firms and the results are also shown.

This chapter compares the status of intellectual freedom in libraries “then” (1970s) and “now” (2005). As starting points for comparisons, it uses two Advances in Librarianship chapters, by Edwin Castagna (Castagna, 1971) and David K. Berninghausen (Berninghausen, 1979), respectively. The US Supreme Court, although somewhat ducking the direct question of library censorship in a school library case in 1982, has consistently upheld intellectual freedom, even in the face of an onslaught of federal laws passed by Congress to restrict speech. The high-water mark came in 1997 when the American Library Association joined the American Civil Liberties Union and others to challenge the Communications Decency Act of 1996, which would have prohibited “indecent” speech on the Internet, an undefined term that could have swept away vast quantities of speech. In 2003, however, the Supreme Court ruled against libraries when it held that a narrower law, the Children's Internet Protection Act (CIPA) is constitutional. This law requires libraries and schools that receive specified federal funds and discounts to use “technology protection measures” to block obscenity, child pornography, and material “harmful to minors.” This chapter looks at these and related cases, as well as the library profession's evolving ethical and political stance on intellectual freedom issues.
