Functional gene transfer from the plastid to the nucleus is rare among land plants despite evidence that DNA transfer to the nucleus is relatively frequent. During the course of sequencing plastid genomes from representative species from three rosid genera (Castanea, Prunus, Theobroma) and ongoing projects focusing on the Fagaceae and Passifloraceae, we identified putative losses of rpl22 in th...

In theory, lump-sum transfers are a way to redistribute wealth without distorting production decisions. Recent agricultural policy reforms are an unusual large-scale application of this concept. The 1996 Federal Agricultural Improvement and Reform (FAIR) Act removed most price-contingent agricultural subsidies and replaced them with Production Flexibility Contracts—lump-sum payments with few ti...

This paper reviews the need for a new land administration vision that takes a more integrated approach rather than the historic fragmented approach and examines change management of land administration and cadastral systems in the context of global drivers of change. This results in the development of a framework for re-engineering land administration systems. After discussing a land administra...

The practicalities of a modern land administration system require some means of boundary adjustment (or repair). Of the possible mechanisms it is concluded that an alternative to adverse possession, statutory encroachment, is preferable to part parcel adverse possession.

Fairly dividing goods among several (possibly strategic) parties is a common problem both in economics and computer science. For instance, a government may wish to divide tracts of land to various organizations or a cloud computing environment may wish to divide computing time among several users. Often, such situations are dealt with via the use of monetary transfers — such as in auctioning of...

Land transfers play a vital role in determining the level of farm machinery service and variety selection by scattered land reduction contiguous enhancement, which are also conducive to poverty alleviation welfare utilization. Based on micro-survey data 898 kiwifruit growers Shaanxi Province, this paper analyzed effect adoption new varieties propensity score matching (PSM) technology. A stepwis...
