The term ‘green jobs’ can refer to employment in a narrowly defined set of industries providing environmental services. But it is more useful for the policy-maker to focus on the broader issue of the employment consequences of policies to correct environmental externalities such as anthropogenic climate change. Most of the literature focuses on direct employment created, with more cursory treat...

The effects of gas composition on the productivity of biomass and intra-cellular fatty acids were investigated in semi-batch cultures of a green alga Chlorococcum littorale (C. littorale) with gas flowing at 100 ml/min under the conditions of temperature of 22 C and light intensity of 4200 lx. Growth rates were enhanced and total fatty acids contents increased by flowing an O2-free gas mixture ...

This study presents an environmental manufacturing system analysis for companies looking for the benefits of environmental management in achieving high productivity levels. When the relationship between environmental costs and manufacturing decisions is examined, it can be seen that the productivity of the company can be increased by adopting a methodology of an environmentally integrated manuf...

In response to recent discussions regarding the ability of hospitals to achieve gains in productivity, we present two methodologies that attempt to measure multifactor productivity (MFP) in the hospital sector. We analyze each method and conclude that the inconsistencies in their outcomes make it difficult to estimate a precise level of MFP that hospitals have historically achieved. Our goal in...

With persistent population growth, a dwindling supply of arable land per capita, and the relatively high income elasticity of demand for food in developing countries, there is a growing need for food supply increases to originate from growth in productivity rather than expansions in inputs. In this paper the authors construct levels of total factor productivity in agriculture for 111 countries ...

Microalgal cultivation using wastewater is now regarded as essential for biodiesel production, as two goals can be achieved simultaneously; that is, nutrient removal efficiency and biomass production. Therefore, this study examined the effects of carbon sources, the N:P ratio, and the hydraulic retention time (HRT) to identify the optimal conditions for nutrient removal efficiency and biomass p...

Based on the panel data of 216 prefecture-level cities in China from 2003 to 2016, this study selected five emission-reduction indicators (industrial SO2 removal rate, soot comprehensive utilization rate industrial solid waste, domestic sewage treatment and harmless waste rate) quantify intensity urban environmental regulations. regulations, authors further studied impact regulations economic q...

Terrestrial ecosystems are characterized by a strong functional connection between the green (plant-herbivore-based) and brown (detritus-detritivore-based) parts of the food web, which both develop over successional time. However, the interlinked changes in green and brown food web diversity patterns in relation to key ecosystem processes are rarely studied. Here, we demonstrate changes in spec...

The environment is one of the most fundamental factors that affects human economic activities. This article investigates whether good firms’ productivity. Using urban public green spaces as proxy environment, we find firms located in cities with more have relatively higher productivity, and result remains robustness after considering endogeneity problem. We also productivity those high-skilled ...
