    Notizen: The unified beta theory of Connor (1984) requires that the market portfolio be well diversified in a given factor structure. Wei (1988) extended Connor's results without relying on this assumption. This note provides an alternative to Wei's result by assuming that residuals from the projection of asset return on a set of k factors follow a joint elliptical distribution.

    Notizen: This paper examines the interface between port cities, urban regions and their transportation systems with respect to Singapore. The development of the regional Singaporean transactional space incorporates the province of Johor in Malaysia and the Riau islands in Indonesia, with the resulting spatial pattern and linkages forming an Extended Metropolitan Region (EMR). An EMR spatial model is presented in which transportation is a key factor. This model explains four processes of territorial development — densification, dissemination, extension and contraction. Densification is a process of spatial accumulation of economic activities within an area and aims at higher levels of productivity. Dissemination is a spatial relocation of unproductive economic activity towards productive areas. Extension is a space/time collapse enabling economic activities to extend over a large territory while maintaining low distribution costs. Contraction is a rationalisation of distribution systems facing growing transportation costs and competition from other systems. Based on the framework provided by the spatial model and available evidence, an assessment of transportation and territorial development in the Singapore EMR is undertaken. The analysis underlines the role of Singapore as a regional transhipment centre and its maritimefland interface function.

    Notizen: Although the last 40 years have witnessed enormous changes within the Third World, many of these have been uneven in their intensity and impact. Indeed, the widening differences between developing countries beg the question as to whether they constitute a cohesive collectivity.This essay makes a comparison between the tropical Third World of the 1950s and that of the 1990s. In many ways the former was much more set and predictable in its relationships and structure than today. However, the changes which have taken place over the last 40 years have not always been to the advantage or lasting benefit of the majority of people in the Third World. A realistic appraisal of future problems and how these might be addressed is thus a central theme of this discussion.

    Thema: Geographie
    Notizen: The development of physical geography in South Asia has generally followed the British and European trends. Diverse themes from denudational chronology to palaeoflood geomorphology have attracted the attention of geomorphologists, particularly in the last 25 years. In addition, geographers’ interest in climatology and biogeography became pronounced during the 1980s. Major methodological shifts in the late 1960s in the west have affected geographical studies in South Asia. These shifts include the use of methods of quantification, remote sensing data, and the increased importance of field and laboratory studies. The second notable aspect in recent times is the accelerating interest amongst physical geographers in environmental studies and the applied aspects of the discipline as well as an increased interaction with scientists in cognate fields. An attempt is also made to identify the key research themes that will interest physical geographers in the near future.

    Notizen: Our knowledge regarding the physical geography of Southeast Asia is incomplete to a surprising extent. This paper reviews the past research, describes the ongoing work, and attempts to identify the future trends. Coverage of such a large area, even for the last 25 years, requires study of publications in several languages and coping with literature which is not easily available. Therefore certain topics. which are prominent in current research and likely to remain so in the future were chosen and reviewed in detail. Such topics include studies related to active plate margin features; the Pleistocene in Southeast Asia; erosion and sedimentation rates; rainforest; river systems; karst in Southeast Asia; coastal geomorphology; and the urban environment.Environmental studies are rapidly gaining importance chiefly because of (a) the destruction of the natural vegetation and the associated loss of biodiversity and (b) the growing problems due to accelerated erosion and sedimentation This trend is likely to continue with accelerated destruction of forests, development of coastal areas, and urbanization of the landscape The direction of research in physical geography of Southeast Asia has been determined by a combination of individual research interest, governmental priorities, and international expectations

    Notizen: This paper attempts to reconcile two major conflicting viewpoints regarding the effects of export expansion on economic growth. The first, export optimism, looks to supply factors such as international competitiveness with the view that a favourable export performance results in significant economic growth for a country. The second, export pessimism, argues that exports only contribute significantly to a country's economic growth when the external demand is favourable. Using the Expansion Methodology, the paper shows that the effects of demand and supply factors on the relationship between export growth and economic growth are about the same. The results suggest that while unfavourable demand weakens the aforementioned relationship, tropical countries can offset this by being competitive in their exports. They also caution against excessive weight being given to export-promotion by export optimists as the exports-growth relationship weakens considerably when the external demand falls.

    Thema: Geographie
    Notizen: In the 1950s, few people had travelled widely through different parts of the tropics and interpretations on tropical landforms, soils, vegetation and climate largely rested on impressions gained from residence or long sojourns in particular tropical countries. Most academic geography on the tropics was then written by expatriates and lacked the perspective gained from long experience of tropical regions. Particular problems of understanding arose as people attempted to extrapolate from one part of the tropics to another. Since then, understanding has advanced enormously, largely through the efforts of tropical scientists working in their own institutions and through the greater technological ability to study tropical lands both remotely and through easier field access. The establishment of a number of field stations, aimed primarily at the biological sciences, but also facilitating the work of geographers, has been a major stimulus to this effort. Concerns over practical issues, particularly local development and global climatic change have prompted new avenues of research, many of which have been assisted by the great increase in data collection in tropical countries. For the future, South-South dialogue between tropical physical geographers is needed to improve their ability to ask meaningful questions so that they can contribute to teach the rest of their discipline more about serious applied and applicable geography.
