Waste Management beyond the Italian North-South Divide: Spatial Analyses of Geographical, Economic and Institutional Dimensions
No full textMany advanced countries have been experiencing waste crises, namely a failure to properly collect and separate urban waste, difficulties regarding both the management landfill sites close to or beyond their full capacity, and the collocation of landfills and incinerators in the territory. These crises appear to be primarily driven by policy failures that include delays in introducing more economically-oriented instruments and a lack of new and diversified tools in waste management and disposal facilities. Italy has been and is a premier case study, with major crises appearing in its less-developed South. Though the North-South divide is a core part of the history of waste and other ‘convergence failures’ and belongs to a typical economic development analysis – it has received attention within ‘Waste Kuznets curves’ literature - we believe nevertheless that other forces and dynamics play an important role. For instance, the process of policy decentralisation that has characterised many good public provisions, which delegates competencies to regions and provinces, is a key aspect behind waste management performance. Within larger autonomous spaces, different provinces can achieve different performances, either by imitating or differentiating themselves from neighbouring agents.
The main research question is to assess whether it is truly just a North-South divide that largely explains the heterogeneous waste management and disposal performances inside Italy, or whether, as we believe, a different type of geo-clustering becomes apparent, which depends more on the quality of waste policy and idiosyncratic socio-economic factors. On the basis of a 2000-2008 dataset that covers 103 provinces over a wide range of information on waste management, socio-economic, structural and policy features, we aim at identifying ‘economic and institutional waste models’ by grouping the performances of provinces over time and space. The dynamic evolution of clusters allows for an analysis of how the system performance has evolved, as well as what weaknesses and strengths in terms of ‘waste management/policy models’ may exist

Tropical timber trade policies : what impact will eco-labeling have?
Full text linkAbout 20 percent of the total production of tropical timber is traded internationally. But for Indonesia, Malaysia, Papua New Guinea, and some countries in West-Central Africa, tropical timber trade accounts for more than 50 percent of production. Although the tropical timber trade has often been blamed for deforestation, the authors find that it contributes much less to deforestation than do poor policies for the production of tropical timber. Lack of tenure rights, short and uncertain logging concessions, low stumpage values, and inadequate monitoring of logging activities are among the major policy failures that help deplete the tropical forests. Trade policies, often identified as an instrument for enforcing environmental objectives internationally, are inefficient instruments for correcting domestic distortions, and in the case of tropical timber trade, may affect the environment perversely. Export and import restrictions ultimately depress the value of an already underpriced resource - the forest. Restrictions on log exports, for example, encourage wasteful processing of logs. Unless sound forest management policies are enforced domestically, the net effect could even be an increase in the rate of deforestation. Import restrictions may have a marginal impact, since trade accounts for less than 20 percent of production and most of the tropical timber is imported in Asia, where such restrictions currently do not exist. Even if import restrictions had a significant impact, it would be in a reduction in value of tropical logs that would make alternative uses of the forest lands more profitable - so the rate of deforestation might not be reduced. Eco-labeling's main strength is its capacity to discriminate (through market signals) in favor of timber produced under sound environmental practices. By contrast, bans and boycotts have an indiscriminate, perverse impact. But if eco-labeling is imposed unilaterally by a subset of countries, its effectiveness will be doubtful. It will lead to trade diversion and potentially perverse environmental results, not to mention an increase in GATT trade disputes. Even if eco-labeling is adopted by all importing countries, there could still be trade diversion in tropical timber products because some consumers may not prefer certified timber, given its higher price. Eco-labeling programs should be designed so that producers see them not as a nontariff barrier but as an instrument for capturing the rents associated with prevailing environmental concerns in the developed world. Consumer education is important to the success of such programs, and eco-labeling programs should be designed accordingly.Environmental Economics&Policies,Forestry,Silviculture,Forests and Forestry,Economic Theory&Research
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Export prospects of Middle Eastern countries : a post-Uruguay Round analysis
Full text linkExports in the Middle Eastern countries should increase from 900 million as a result of the tariff cuts agreed on in the Uruguay Round, according to the author.This represents an annual expansion of less than 1 percent. Projected gains are small because the erosion of tariff preferences that Middle Eastern countries received in OECD markets offset the positive effects of reduced most-favored-nation tariffs on nonpreference-receiving products. And petroleum, the main Middle Eastern export--which generally faces zero or low tariffs--is unaffected by the Uruguay Round reductions. Egypt's projected gains (about $20 million, or under 0.5 percent of total exports) are concentrated largely in agricultural exports to the European Union and manufactures in the United States. Israel should experience net trade losses because of the erosion of its free trade preferences in the European Union and the United States. The Uruguay Round made major progress in removing nontariff barriers that Middle Eastern exports face, especially in agriculture, textiles, and clothing. But with the removal of the Multifibre Arrangement, international trade in textiles and clothing will become much more competitive. Middle Eastern countries must adopt measures to cut costs and increase efficiency to remain viable exporters. As a result of what was achieved in the Uruguay Round, the average OECD nontariff barrier coverage ration for Middle Eastern exports should fall from a current 10 percent to between 1 and 2 percent. Net food importing countries could be adversely affected by the higher international food prices expected to result from the Uruguay Round agreement. There is a clear priority for net food importers to adopt reforms stimulating domestic production. Prospects for increased trade in the Middle East are constrained by the similar comparative advantages and export profiles of many Middle Eastern countries. The most favorable prospects for intraregional trade appear to be between countries such as Cyprus, Israel, Lebanon, and Turkey--net energy importers--and the rest of the region.Trade Policy,Economic Theory&Research,Agribusiness&Markets,Environmental Economics&Policies,Export Competitiveness,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Economic Theory&Research,Trade Policy,Agribusiness&Markets,Export Competitiveness
Variations on the Author
Full text link“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

Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
