Preferential trade agreements and manufactured goods exports: does it matter whom you PTA with?

Abstract: This article explores two questions. First, do preferential trade agreements (PTAs) affect manufactured goods exports of developing countries? Second, does it matter for developing countries whom they sign the PTAs with? We find that the answer to both questions is yes. Using bilateral manufactured goods exports data from 28 developing countries during 1978–2005; we find that South–South PTAs have a significantly positive effect on manufactured goods exports. In contrast, no such effect is detected in the case of South–North PTAs. We confirmed the robustness of these findings to estimation methodology, sample selection, time period, zero trade flows and multilateral trade resistance.

The use of supervenience in dynamic-world planning

Abstract: This paper describes the use of supervenience in integrating planning and reaction in complex, dynamic environments. Supervenience is a form of abstraction with affinities both to abstraction in AI planning systems and to partitioning schemes in hierarchical control systems. The use of supervenience can be distilled to an easy-to-state constraint on the design of multilevel dynamic-world planning systems: world-knowledge up, goals down. We present the supervenience architecture which embodies this constraint, and contrast it to the subsumption architecture of Brooks. We describe the performance of an implementation of the supervenience architecture on a problem in the HomeBot domain, and we conclude with a discussion of the role that supervenience can play in future dynamic-world planning systems.

Optical Emission Inductively Coupled Plasma in Environmental Analysis

Abstract: The ability of the inductively coupled plasma-atomic (or optical) emission spectroscopy (ICP-AES (or OES))) system to perform multielement trace metal analysis of environmental samples provided commercial laboratories with the needed incentive to enter into the business of efficient trace metal analysis. Previously, trace metals were typically analyzed using colorimetric techniques, which were both cumbersome and subject to interferences, or flame atomic absorption techniques, which, although almost interference free, were labor intensive owing to their one-element-at-a-time analytical mode. Even the furnace atomic absorption technique, for years the standard bearer of low-level trace metal analysis, is giving way to axial and radial viewed ICP-AES techniques. Now, ICP-AES has become an affordable and well-established multielement analytical method. Taking the USEPA (United States Environmental Protection Agency) SW-846 solid waste analysis manual as an example, this article reviews the methods used for the preparation of samples and the ICP-AES analysis of the prepared samples for trace metals in environmental matrices. This review includes recent developments in front-end improvements in ICP-AES and a detailed overview of the quality control (QC) requirements for environmental ICP-AES analysis.

A Latina space: Ethnicity as an intersubjective third

Abstract: This paper discusses the intersubjective use of ethnicity in a case. The author reviews the role of ethnicity in the psychoanalytic tradition and explores the creative potential of intersub‐jectivity. Applying Ogden's concept of the analytic third based on Winnicott's ideas, the author elaborates on the psychodynamic potential space co‐created by the similarities and differences of ethnic identities.
