Economists now recognize that, along with physical and human capital, environmental resources should be viewed as important economic assets, which can be called natural capital . Three recent debates have emerged over the role of natural capital in economic development. First, as many ecological services are unique, does the environment have an “essential” role in sustaining human welfare, and ...

The inhibition by opiates of the PGE2-induced formation of cAMP in slices from rat brain striatum was investigated. A maximal, 3.5-fold increase over the basal level of cAMP was obtained with an EC50 for PGE2 of 3 microM. Opiate agonists of both mu and kappa type were inhibitory. The IC50 values for morphine, levorphanol and ethylketocyclazocine (EKC) were 110 nM, 80 nM and 25 nM, respectively....

Environmental sustainability is a burning fact worldwide, especially in developing nations. Equitable economic development, environmental protection, energy efficiency and security have been placed at the apex of discussant policy formulation. This paper establishes relationship between trade quality Sub-Saharan Africa (SSA). Following Kuznets Curve (EKC) theory, we investigate existence an inv...

This paper extends the “sources of growth” explanation for Environmental Kuznets Curve (EKC) proposed by Copeland and Taylor in a concise theoretical framework, that is, when sources growth are transformed from physical capital labor to human knowledge, environmental pollution could at first rise then fall with sustainable per capita income. Using provincial panel data 1995 2017 mainland China,...

The ship-borne observations of the temperature, salinity, pCO2 (1995–2020) and satellite geostrophic velocity fields, SST, chlorophyll concentration are used to identify factors that determine spatio-temporal variability seawater parameters on western boundary subarctic North Pacific. In winter, surface layer East Kamchatka Current (EKC) was characterized by two types water: waters with a negat...

Although panel data have been used intensively by a wealth of studies investigating the GDP-pollution relationship, the poolability assumption used to model these data is almost never addressed. This paper applies a strategy to test the poolability assumption with methods robust to functional misspecification. Nonparametric poolability tests are performed to check the temporal and spatial homog...

The environmental issue has become a global problem that needs to be examined frequently, motivating researchers investigate it. Thus, the present study investigated asymmetric impact of globalization, economic growth and natural resources on ecological footprint in presence Kuznets curve (EKC) Thailand. used annual time series data from 1970 2018. applied novel method nonlinear autoregressive ...
