Common belief and some empirical evidence indicates that productivity of a farmer may increase with age, reach some maximum level, and then decrease with further age (Tauer 1984; Tauer 1995). If productivity exhibits a life-cycle pattern, then productivity of agriculture may decrease as the U.S. farm population continues to age. Lifecycle changes are also critical in planning for succession of ...

Tourism development consumes ecological resources to varying extents while bringing economic benefits; tourism eco-efficiency (TEE) assessment has thus become an area of major focus in destination sustainability research. This paper intends examine the spatiotemporal characteristics and driving factors changes 36 tourist cities on Chinese mainland from 2010 2019, using a super-slacks-based meas...

The productivity change of a decision making unit (DMU) between two time periods can be evaluated by the Malmquist productivity index. In this study, we propose a method to compute the Malmquist productivity index in several time periods (from the first to the last periods) on interval data in data envelopment analysis (DEA). Then, the obtained Malmquist productivity index is compared with Malm...

the malmquist productivity index evaluates the productivity change of a decision making unit (dmu) between two time periods. in this current study, a method is proposed to compute the malmquist productivity index in several time periods (from the first to the last periods) in data envelopment analysis (dea) and then, the obtained malmquist productivity index is compared with malmquist productiv...

This paper investigates the impact of Malmquist bias on the distance to the Virgo cluster determined by the H0 Key Project using M100, and consequently on the derived value of H0. Malmquist bias is a volume-induced statistical effect which causes the most probable distance to be different from the raw distance measured. Consideration of the bias in the distance to the Virgo cluster raises this ...

Performance measurement is always one of the most important tasks of managers, so knowledge management is measurement knowledge, and if we can measure something, we can no doubt control it, and therefore we cannot manage it. In this paper, according to the Malmquist productivity index, an index is used to determine the progress and regress of a unit. This index is defined by the boundary change...

The Malmquist bias in luminosity distances for gaussian standard candles is discussed within cosmological models where the Euclidean r3-law for volumes and r−2-law for fluxes is not valid. Furthermore, the influence of K-corrections and luminosity evolution are analyzed. It is noted that the usual way of comparing theoretical predictions and data points in the Hubble diagram (log z vs. m) shoul...
