    Authorship trends in Indian wildlife and fisheries literature - a bibliometric study

    Get PDF
    The authorship and collaborative research patterns in Indian wildlife and fisheries based on the data collected from "Wildlife Review and Fish Review" published bettween 1980 to 1989 are studied. The proportion of single authored papers has decreased from 63.68% in 1980 to 52.74% in 1989. During the same period there was an increase in the average number of authors per paper from 1.57 in 1980 to 1.70 in 1989. The degree of collaborative research also increased from 0.36 to 0.47

    River Discharge

    In 2014, combined discharge from the eight largest Arctic rivers (2,487 km3) was 10% greater than average discharge for the period 1980-1989. Values for 2013 (2,282 km3) and 2012 (2,240 km3) were 1% greater than and 1% less than the 1980-1989 average, respectively. For the first seven months of 2015, the combined discharge for the six largest Eurasian Arctic rivers shows that peak discharge was 10% greater and five days earlier than the 1980-1989 average for those months

    Biogeochemical ecology of six species of Sphagnum in Costa Rica

    Get PDF
    There is very little information on the biogeochemical ecology of Sphagnum species in tropical regions. The majority of the ecological information on Sphagnum species in the tropics consists of general habitat information and pH values that are reported in new species descriptions and regional floras such as those of Crum (1980, 1989), Crum and Buck (1988), Karlin (1991), and McQueen (1989)

    Evaluating the Temporal and the Spatial Heterogeneity of the European Convergence Process, 1980-1999

    Get PDF
    In this paper, we suggest a general framework that allows testing simultaneously for temporal heterogeneity, spatial heterogeneity and spatial autocorrelation in b-convergence models. Based on a sample of 145 European regions over the 1980-1999 period, we estimate a Seemingly Unrelated Regression Model with spatial regimes and spatial autocorrelation for two sub-periods: 1980-1989 and 1989-1999. The assumption of temporal independence between the two-periods is rejected and the estimation results point to the presence of spatial error autocorrelation in both sub-periods and spatial instability in the second sub-period, indicating the formation of a convergence club between the peripheral regions of the European Union.b-convergence models, spatial autocorrelation, convergence clubs, temporal instability

    Evaluating the temporal and the spatial heterogeneity of the European convergence process, 1980-1999

    In this paper, we suggest a general framework that allows testing simultaneously for temporal heterogeneity, spatial heterogeneity and spatial autocorrelation in beta-convergence models. Based on a sample of 145 European regions over the 1980-1999 period, we estimate a Seemingly Unrelated Regression model with spatial regimes and spatial autocorrelation for two sub-periods: 1980-1989 and 1989-1999. The assumption of temporal independence between the two periods is rejected and the estimation results highlight the presence of spatial error autocorrelation in both sub-periods and spatial instability in the second sub-period, indicating the formation of a convergence club between the peripheral regions of the European Union.beta-convergence models, spatial autocorrelation, convergence clubs, temporal instability

    A Review of World Salmon Culture

    Get PDF
    World farmed salmon production reached 145,000 metric tons (t) in 1988 and an estimated 217,000 t in 1989. The latter figure is comparable to the U. S. annual salmon catch (about 250,000 t) and is approaching one-third the size of the world wild salmon catch (about 700,000 t). The rapid expansion of farmed salmon supplies in the late 1980's has led to sharp price decreases. Lower prices have forced some farmers out of business, but at the same time, a large number of farmers first began harvesting salmon on a commercial scale as the 1980's ended. Farmed salmon production could exceed 270,000 t in 1990

    ‘History of the Official Currency and the Central Bank of Cyprus’ Preliminary Conclusions for the Period 1960-2007

    Get PDF
    The period 1960 to 2007 – when the Cyprus pound was legal tender – is examined with a view to relating the major turning points of exchange, fiscal and monetary policies to their likely causes and consequences. Assumptions are made and conclusions are drawn regarding: the four periods of exchange rate policy (1960-1972, 1972-1992, 1992-1999, 1999-2007); the three phases of bank claims on the government sector (1960-1966, 1966-1975, 1975-2007); the five swings of bank credit to the private sector (1960-1965, 1965-1975, 1975-1984, 1984-2007); the five oscillations of the banking system’s foreign assets (1960-1971, 1971-1980, 1980-1989, 1989-1998, 1998-2007); the parallel tracks of GDP, CPI and the average annual salary during the 47 years under review. The above methodology is applied to the analysis and synthesis of the monetary and credit history of Cyprus between 1878 and 2007.Economic history, business cycle, exchange rate, fiscal policy, private credit, price index, wage adjustment
