Patterns of fertility change in Ghana: a time and space perspective

This article examines fertility change in Ghana based on a time and space perspective. The sample draws on three birth cohorts of women born in the 1950s, 1960s and 1970s, resident in five distinct societies selected from three settlements in Ghana. The findings of the study show that fertility change is occurring in a socioeconomic and geographically distinct manner. Significant fertility declines are traced to the 1960 birth cohorts in all the study areas. For the 1970 cohort this decline continues in the elite areas whereas the urban indigenous areas exhibit a rise in teenage fertility which is not, however, followed by higher fertility after the age of 20. In the rural area fertility rises from the 1960 to the 1970 cohort up to age 24, which is the end point of study for this cohort. The spatial variability between the five study areas has profound implications for the ongoing fertility change in Ghana and Sub-Saharan Africa.     

WHY DO WE CARE ABOUT POST‐HUMANISM? A CRITICAL NOTE

What is disclosed in the questioning of the human being in post‐humanism? Addressing this question in congruence with Heidegger's questioning of being in Being and Time, we end up with two discoveries: first, that the characteristic of Dasein, as the being of the questioning, already carries the same implications as the post‐human figure, and second, that questioning in this sense is indicative of the effort of realizing anew scientific space for conceptualizing the human being as non‐substantialist. Conceived of in this way, however, post‐humanism is a result of a very human effort indeed.     

Twenty Years of Mobilising around AIDS in China: The Main Actors and Influences behind Organisational Growth

AIDS-related work and advocacy is one field that has spurred considerable activity among Chinese NGOs in the past two decades. This article explains processes leading to institutional changes that are necessary for allowing more NGOs to emerge and operate, and shows how international, domestic and local actors and influences have steered developments leading to organisational growth. The article applies new institutionalism theory and highlights differences between formal and informal institutions in explaining change and continuity for NGOs and their relations to state and government in this particular field.     

An Empirically Based Implementation and Evaluation of a Hierarchical Model for Commuting Flows. 一种基于经验的层状通勤流模型实现与评估

This article provides an empirical evaluation of a hierarchical approach to modeling commuting flows. As the gravity family of spatial interaction models represents a benchmark for empirical evaluation, we begin by reviewing basic aspects of these models. The hierarchical modeling framework is the same that Thorsen, Ubøe, and Nævdal (1999) used. However, because some modifications are required to construct a more workable model, we undertake a relatively detailed presentation of the model, rather than merely referring to the presentation in Thorsen, Ubøe, and Nævdal (1999) . The model uses a hierarchical specification of a transportation network and the individual search procedure. Journeys to work are determined by the effects of distance deterrence and of intervening opportunities, and by the location of potential destinations relative to alternatives at subsequent levels in a transportation network. The model calibration uses commuting data from a region in western Norway. The estimated parameter values are reasonable, and the explanatory power is very satisfactory when compared with the results of a competing destinations approach.     

Challenges to Bridging Discrepant Knowledge Bases: A Case Study of the Norwegian Centre for Offshore Wind Energy

From a theoretical perspective, it is possible to enhance the innovation of firms and institutions by combining the analytic (scientific) knowledge base of research and development (R&D) institutions with the synthetic (practical) knowledge base of industries. Such combinations of knowledge are also believed to support regional development. One such initiative to bridge knowledge from the R&D sector and industry is the Norwegian Centre for Offshore Wind Energy (NORCOWE). However, as our case study shows, it is hard to bridge knowledge from these two partner groups. We found that this is mainly because of differences in the partners' timelines (long versus short), their attitudes toward knowledge (research based versus experience based), application of the knowledge (knowledge per se versus commercialization), and organizational dimensions (linear/closed process versus interactive/open process). These differences show that the knowledge bases of these two groups may not just be different; they can also be seen as discrepant. We also argue that the NORCOWE initiative is influenced by a “policy push” logic. This implies that the initiative was not properly embedded in the industrial or R&D institutions before being launched, but was instead driven by a political will to promote the development of a new renewable energy source.     

The Challenges and Potentials of Archaeological Heritage in Africa—Cape Verdean Reflections

This paper considers three different ways that heritage can be considered fragile—as a reference to the conservation status of the physical heritage, as a concern for the meaning of the heritage, and in terms of threats to the knowledge potentials. It also briefly considers any special conditions that may characterise the threats to heritage in Africa and the consequential challenges to its heritage managers and politicians. On this basis, the experiences of working on one of the first systematic archaeological projects in Cape Verde are used to think about how these challenges are encountered within a specific place but from the viewpoint of foreigners and archaeologists.     

What is the VAT? The policies and practices of value added tax on ebooks in Europe

This article addresses reduction of or exemption from value added tax (VAT) as a cultural- and media policy instrument and analyses the VAT policies on ebooks within the European Economic Area. Examining an area of media and policy studies that is largely overlooked, the article is partly an empirical analysis of VAT policies and partly a discussion paper raising issues applicable to other media sectors and of political and societal relevance. Section 1 of the article conceptualises VAT reduction/exemption as a media and cultural policy tool within national and supranational policy frameworks. Section 2 gives a comprehensive overview of the application of VAT on print books and ebooks in Europe and discusses some consequences of the concrete taxation practices. Section 3 reports and discusses initiatives to alter the European VAT policies on digital media and cultural products and services.
