Main Change

This paper presents an overview of the proposed changes in composite design provisions for the upcoming American Institute of Steel Construction (AISC) 2005 Specification. The main change insofar as member design is concerned relates to how composite column design is handled. The new provisions will provide a more smooth transition between design of composite and reinforced concrete columns and a more rational, mechanistically-based design procedure. Insofar as member detailing is concerned, the main change is in the strength values for shear studs, which have been considerably lowered under some circumstances. The paper also presents some ongoing developments in composite floor and lateral load resisting systems, and concludes with a short description of an unusual composite truss.

Gender Based

Sexuality, gender, and class (with race, ethnicity, physical mobility, and other social categories related to power) are deeply implicated in the constitution of each other as social relations. Spatial structures and conflicts that are constitutive of class relations are therefore also constitutive of sexuality. An examination of recent developments in feminist, lesbian and gay, and radical social theory, and certain elements of the historical geography of capitalism, reveals specific ways in which this is so. Urban spatial designs in Britain and the USA in the 19th and 20th centuries, for example, implicate hegemonic constructions of sexuality in gender-based and class-based spatial divisions of labor. Similarly, struggles over the social definitions of sexuality have involved individuals and groups recoding spaces that have been devalued by the market in potentially counterhegemonic ways. Thus, struggles over sexuality manifest themselves as struggles over sexual representations of, and sexual symbols in, space as well as over spatial organization. Indeed, these sorts of struggles may actually be more important in the contemporary era than those concerning the spatial organization of sexuality. This is because the sociospatial construction of otherness, which has as much to do with representational and symbolic space as with physical space, has become key to the survival of capitalism.

In his address to the Annual Conference of the Australian Behaviour Modification Association in 1986, Dr. Robin Winkler chose the topic “The social history of behaviour modification in Australia” (Winkler & Krasner, 1987). Dr. Winkler was concerned to recognise the contributions of a number of individuals who were prominent in the new movement in the 50s, 60s and 70s. My aim is rather different. I want to try to capture what the early workers were trying to achieve, what they saw as the problems, and how they viewed the early developments. I will then look at more recent developments in Australian behaviour therapy, and try to characterise its current status. Finally, I'll discuss what seem to me the major current problems, and suggest some possible solutions. Where I feel able to do so, and it seems to me appropriate, I'll make some comparisons with the situation in the USA. Many of the more general points, of course, will be relevant to behaviour therapy in any country.

Recent Developments

Significant advances have been made in recent years in research, development, interpretation, and application of cone penetration testing. The addition of pore pressure measurements during cone penetration testing has added a new dimension to the interpretation of geotechnical parameters.The cone penetration test induces complex changes in stresses and strains around the cone tip. No one has yet developed a comprehensive theoretical solution to this problem. Hence, the cone penetration test provides indices which can be correlated to soil behaviour. Therefore, the interpretation of cone penetration data is made with empirical correlations to obtain required geotechnical parameters.This paper discusses the significant recent developments in cone penetration testing and presents a summarized work guide for practicing engineers for interpretation for soil classification, and parameters for drained conditions during the test such as relative density, drained shear strength, and deformation characteristics of sand. Factors that influence the interpretation are discussed and guidelines provided. The companion paper, Part II: Clay, considers undrained conditions during the test and summarizes recent developments to interpret parameters for clay soils, such as undrained shear strength, deformation characteristics of clay, stress history, consolidation characteristics, permeability, and pore pressure. The advantages and use of the piezometer cone are discussed as a separate topic in Part II: Clay. The authors' personal experiences and current recommendations are included. Keywords: static cone penetration testing, in situ, interpretation, shear strength, modulus, density, stress history, pore pressures.

Recent developments in US law: Remedies and damages for improper patent listings in the FDA's Orange Book

The Drug Price Competition and Patent Term Restoration Act (Publ. No. 98-417, 98 Stat. 1585 (1984)), commonly known as the Hatch–Waxman Act (the Act) provides the statutory framework by which most generic drugs are approved for marketing in the USA. Most provisions in the Act concern the standards and procedures the US Food and Drug Administration (FDA) must follow to approve generic drugs. A relatively small number of the provisions, however, create a framework for resolving patent disputes between the brand and generic pharmaceutical companies. These provisions have been the subject of much recent activity, in the US Courts, in Congress, in the FDA itself and in the White House. Much of the activity revolves around a publication by FDA entitled Approved Drug Products with Therapeutic Equivalence Evaluations, known colloquially as the Orange Book.Under present FDA practice, the mere listing of a patent in the Orange Book corresponding to a brand pharmaceutical product invokes a number of statutory provisions that confer valuable exclusivity rights on the brand company, and also possibly on one or more generic companies. This situation creates a strong incentive for patentees and brand pharmaceutical companies to list patents in the Orange Book. A number of recent court cases have addressed the remedies and damages available when the listing is found to be improper. Thus far, the most successful means to challenge or prevent improper listings has been through private and governmental enforcement of the antitrust laws.
