Natural resource accounting
No full textThere is as yet no consensus on the most appropriate way to incorporate the degradation of environmental capital into national income accounting procedure. Net product is currently derived by deducting from gross product the depreciation of man-made capital only. Deducting depreciation of natural capital in a similar manner will give a figure for ‘true’ net product that provides a better indicator of that level of current income which is sustainable into the future. The ‘user cost’ and ‘net price’ methods of calculating the value of natural resource depreciation are analysed and assessed. On the basis of this assessment, the net price method is then used to adjust the national accounts of Zimbabwe for depletion of forests, soils and mineral resources, for the period 1980 to 1989. The results suggest that economic depreciation of natural resources represents approximately 2% of annual GDP, although this is regarded as a significant underestimate. The implications for integrating natural resource depletion into policy making, within the current national political climate, are then addressed.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textDefining the category of 'small' states
No full textThere is no widely accepted definition of a small state. Most previous definitions have been based upon arbitrarily chosen cut-off values of selected criteria. The present study attempts to categorize the size of 190 states according to population, land area and total income. An initial categorization is based upon observation of each series to identify discontinuities in the distributions. Cluster analysis is then employed to identify groups of countries that share similar size-related characteristics. A classification based on non-hierarchical cluster analysis is proposed, generating four clusters from equally spaced initial cluster-centres. On this basis, 79 countries are classified as 'small'. The reasons for deviation from recent categorizations of small countries are explored, the primary cause being the inclusion of some countries with very low levels of income.

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Nonuse Values and the Environment: Economic and Ethical Motivations
No full textNonuse values are a potentially very important, but controversial, aspect of the economic valuation of the environment. Since no use is envisaged by the individual, a degree of altruism appears to be the driving force behind nonuse values. Whilst much of the controversy has focused upon measurement issues associated with the contingent valuation method, this paper concentrates on the underlying motivations, whether ethical or economic, that form the basis for such values. Some fundamental aspects of defining and quantifying economic nonuse values are considered, and possible motives for attributing value to the environment are analysed, making a clear distinction between 'selfish' altruism and 'selfless' altruism. The difference has crucial implications for economic valuation and for assessing individuals' willingness to pay for environmental quality. The concept of Safe Minimum Standards is introduced as a means of supplementing purely economic methodology to incorporate ethical concerns into decision making.nonuse values, self interest, altruism, safe minimum standards
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
