Cross-linguistic Variations of pro Licensing Conditions

Null subject languages are generally called pro-drop languages. According to the generative syntactic analysis, languages can be divided into pro-drop and non-pro-drop languages. Subject Agreement (AgrS) is argued to be the licensing condition for the null subject languages. Nevertheless, pro-drop licensing conditions may vary in different languages. This paper analyzes various null subject languages with different pro-drop licensing conditions from cross-linguistic perspective

Combined Effects of Fronts, Upwelling and the Biological Pump on Organophosphate Esters in the Changjiang (Yangtze) River Estuary During Summer

Estuarine and coastal environments are important transport pathways and regional sinks for anthropogenic pollutants. In this study, the occurrence and transport of the continuously released organophosphate esters (OPEs) was investigated together with physical and biochemical parameters throughout the water column in the Changjiang (Yangtze) River estuary during the summer. Total dissolved and particulate OPEs showed great spatial heterogeneity, with mean concentrations of 550 ± 280 ng/L in the estuary, 110 ± 270 ng/L in the front/upwelling zone, and 410 ± 450 ng/L in the continental shelf. OPE concentrations in the estuarine bottom waters were high due to massive terrestrial/sediment inputs. In contrast, the “surface enrichment and depth depletion” of OPEs in the continental shelf was closely related to seasonal stratification. Reduced OPE concentrations were observed in the frontal/upwelling zone due to isopycnal heaving. Frontal activity and upwelling induced phytoplankton blooms in the coastal regions, which jointly contributed to elevated OPEs beneath surface water with high phytoplankton aggregation. The OPEs mainly originated from wastewater treatment plant discharges, industrial pollution and consumer products. These OPEs generally posed a low ecological risk to aquatic lives, but their long-term effects cannot be ignored due to their continuous high production, usage and release

Investment and revenue cap under incentive regulation: The case study of the Norwegian electricity distributors

Electricity distribution operators are regulated as monopolies around the world. Incentive regulation is further applied to relate their allowed revenues (revenue cap) to cost efficiency and investment. Incentive regulation varies cross countries and has evolved over time for individual countries. Norway is one of the first countries reforming the network distributors by incentive regulation. Using the long time series data, we evaluated the impact of the Norwegian regulation regimes on firms’ investment. The panel data model includes common time-varying factors to control firm heterogeneity. The cross-section dependence test is further employed to test the relationship between investment and revenue cap in different regulation regimes. The empirical findings confirm a dynamic pattern of investment behavior between regimes, in terms of both the unobserved common factors and the cross-section dependence between investment and revenue cap. This study provides an interesting solution for incentive evaluation and contributes to the management accounting literature in terms of econometric techniques.publishedVersio
