Upper Cretaceous-Paleogene stratigraphy of ODP Sites 113-689 and 113-690
No full textThis contribution summarizes the biostratigraphy of planktonic foraminifers, calcareous nannofossils, and benthic foraminifers, in combination with the magnetostratigraphy, carbon and oxygen isotope stratigraphy of benthic foraminifers, and CaCO3 stratigraphy for the Maestrichtian through Paleogene calcareous sequences recovered at Sites 689 and 690 on Maud Rise (at about 65°S, eastern Weddell Sea, Antarctica). These data represent the southernmost calciumcarbonate record available for that interval, and thus extend the biostratigraphic and isotopic database to higher latitudes. Sites 689 and 690 form the southernmost anchor of a north-south transect through the Atlantic Ocean for Paleogene biostratigraphy and chemostratigraphy
Small and medium-size enterprises in economic development : possiblities for research and policy
Get PDFThe World Bank's most important long-term advantage in promoting development, says the author, may lie in opportunities to address related obstacles simultaneously. It could mount concurrent efforts to address the problems of small and medium-size enterprises in a particular sector, region, or economy, for example. It could address the conditions of founding new firms, providing finance or technical assistance, developing mutual support institutions, resolving disputes, and perhaps reducing counterproductive government interventions. Were the Bank to follow such a coordinated approach, programs could be designed to generate data to illuminate the impacts and interactions of various elements of policy. These data could be exploited, then, in research designs, or even the design of management information systems, shaped by program evaluation. The author proposes four general issues for research (plus a series of topics for each issue). (1) Can Bank initiatives involving small and medium-size enterprises in developing countries facilitate the entry of these enterprises into similar learning relationships with other firms - foreign firms, larger firms in their own countries, or each other? (2) The economic significance of high"turbulence"(entry and exit rates) in small-firm populations is poorly understood. The fact of high turbulence is well-documented in industrial countries; it is not for developing countries, but available data suggest a broadly similar pattern. Are high failure rates for small businesses symptomatic of an important shortcoming in the system of economic organization itself? Or should the unit of analysis be the enterprise, the entrepreneur, or the entrepreneur's family? (3) Is the apparent trend favoring a larger economic role for smaller production units autonomous rather than induced by other changes? Does it depend on general operating factors such as the declining costs of communication and computation? (4) The rate of learning by a small firm may depend on the nature of its transacting partner. Certain multinational enterprises make good teachers, for example, but certain local labor markets or markets for consumer goods and services may not be well-positioned for relevant learning. They may learn well how to adjust to local circumstances but not to the international diffusion of technology and ways of organizing (the main source of hope for developing countries). Perhaps Bank policy should be more concerned with transaction patterns.General Technology,Environmental Economics&Policies,Decentralization,ICT Policy and Strategies,Small and Medium Size Enterprises,Environmental Economics&Policies,General Technology,Small and Medium Size Enterprises,ICT Policy and Strategies,Small Scale Enterprise

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

Adoption and diffusion of no tillage practices in Southern Spain olive groves
Get PDFThis paper analyses the process of adoption of no tillage in South-eastern Spain’s olive groves. Olive tree groves in South-eastern Spain’s mountainous areas are subject to a high risk of soil erosion, which is the main environmental problem for this crop, and have to incur in high costs of soil conservation. This results in a greater difficulty to comply with the practices required to benefit from both the single payment and agri-environmental schemes. In many high-steeped areas, farmers have opted for non-tillage practices as an alternative to other conservation practices. Using our own data from a survey carried out in 2006 among 215 olive tree farmers from the Granada Province in Southern Spain regarding the adoption of soil conservation and management practices, we model the diffusion process of no tillage practices using several specifications (logistic, Gompertz and exponential). We also estimate an ordered probit model to analyse which socio-economic and institutional factors determine the adoption of no tillage. Our results show that 90% of farmers in the area of study perform no tillage with either localized (21%) or no localized (69%) application of weedicides. The diffusion process of no tillage has been very intense since the middle nineties, and has been based on the interactions among farmers in the area of study rather than in external factors such as EU policies or extension services. Among other relevant factors that positively affect the adoption of no tillage practices in general, such as farm size and irrigation, the probability of a farmer adopting no tillage with non-localized application of weedicides increases when there is a relative that will continue with the farming activity, what causes the farmer to incorporate long term effects in his farming decisions, when the farmer is only a manager or when he bought the farm rather than inherited it (i.e. on more professionalized farms), and with his educational level. These results confirm some findings from previous studies in other nearby areas.Spanish olive groves, soil erosion, no tillage, Crop Production/Industries, Land Economics/Use,
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
