Bed planted wheat systems offer a new alternative for the traditional wheat producer to provide opportunities for crop rotation, more efficient use of water, and new techniques of nutrient management. This study was conducted to determine if planting winter wheat (Triticum aestivum L.) in Oklahoma on raised beds can maintain grain yields while providing more options in the cropping system. Expe...

Plant-plant interactions that change along environmental gradients can be affected by different combinations of environmental characteristics, such as the species and planting density ratios. Suaeda salsa and Scirpus planiculumis are regionally dominant species in the Shuangtai estuarine wetland. Compared with non-clonal S. salsa, clonal S. planiculumis has competitive advantages because of its...

This brief essay provides a selective discussion of how in recent years economists in the neoclassical tradition have addressed the questions whether and how immigration affects native workers’ labour market outcomes. In particular, it discusses: the distinction between the displacement, productivity and amenity effects of immigration; the issues that arise in using wage changes to identify tho...

Abstract Cities host diverse people and their mixing is the engine of prosperity. In turn, segregation inequalities are common features most cities locations that enable meeting with different socio-economic status key for urban inclusion. this study, we adopt concept economic complexity to quantify sophistication amenity supply at locations. We propose neighborhood connected ability attract vi...

In this paper, we tackle the satisfiability problem for multi-context systems. First, we establish a satisfiability algorithm based on an encoding into propositional logic. Then, we propose a distributed decision procedure that maximally exploits the potential amenity of localizing reasoning and restricting it to relevant contexts. We show that the latter approach is computationally superior to...

This paper employed the endogenous switching regression and propensity score matching methods to analyse the impact of row-planting technology on rice productivity using 470 rice farms in Northern Ghana. The empirical findings showed that the adoption of row-planting technology exerted greater positive impact on rice yields of smallholder farmers. In addition, rice yields of adopters and non-ad...
