The loss of biodiversity is threatening ecosystem productivity and services worldwide, spurring efforts to quantify its effects on the functioning of natural ecosystems. Previous research has focused on the positive role of biodiversity on resource acquisition (i.e., niche complementarity), but a lack of study on resource utilization efficiency, a link between resource and productivity, has ren...

This paper estimates total productivity change over time and de-composes it into technically efficient change and technological change for an Iranian Tile and Ceramic Industry with combining Data Envel-opment Analysis and Malmquist Productivity index. In combining these two techniques the outputs from DEA are used as inputs for Malmquist productivity index. In the current study, Tile and Cerami...

BACKGROUND The aim of this study was to reveal the association between airflow limitation (AL) severity and reduction with work productivity as well as use of sick leave among Japanese workers. METHODS This cross-sectional study included 1,378 workers who underwent a lung function test during a health checkup at the Japanese Red Cross Kumamoto Health Care Center. AL was defined as forced expi...

Using pre-and post-reform industry-level panel and aggregate national infrastructure data, this paper examines the effects of infrastructure on industry productivity in Cameroon, controlling for trade variable and correcting for the likely endogeneity of infrastructure and other regressors. The empirical strategy involves, (i) estimation of production functions augmented by the infrastructure q...

In boreal conifers, maximum latewood density (MXD) of annual rings varies in response to warm-season temperatures. Vegetation productivity can be estimated using the Normalized-DiŒerence Vegetation Index (NDVI) calculated from satellite sensor data. Ground measurements related to productivity are required in order to evaluate these estimates. MXD from three boreal sites was compared with estima...

Data Envelopment Analysis is a linear programming technique for assessing the efficiency and productivity of decision making units (DMUs). Over the last decade, DEA has gained considerable attention as a managerial tool for measuring performance. The flexibility in selecting the weights in standard DEA models deters the comparison among DMUs on a common base. Moreover, these weights are unsuita...

Drought is one of the major environmental stresses that adversely affect crop growth and productivity worldwide. For evaluation of drought stress on grain yield, yield components and drought tolerance indices, 20 genotype of rapeseed (Brassica napus L.) was studied in an experiment based on a randomized complete blocks design with three replications in two different conditions (stress and non-s...
