Current issues in Chinese Neolithic archaeology

Every year archaeologists in China discover numerous rich sites demonstrating significant regional variability in Neolithic cultures, primarily from about 6500 B.C. to 1900 B.C. This paper discusses a topic not covered in detail in current or forthcoming publications, the origins and development of agricultural systems. Recent fieldwork in both northern and southern China suggests that initial steps toward settled agricultural villages began circa 11,000 B.P. I review evidence for the cultivation of millet, rice, and other plants as well as animal husbandry in different regions of China. There are several later Neolithic sites in northern China with evidence for rice cultivation. I suggest how future research projects can investigate regional variation and change over time in subsistence and settlement during the Neolithic Period.     

Nearest Neighbour Analysis and Wedge-Tailed Shearwater Burrow Patterns on Heron and Masthead Islands,Great Barrier Reef

Heron and Masthead Islands in the Capricorn Group of the Great Barrier Reef Marine Park support major nesting colonies of the wedge-tailed shearwater. The distribution pattern of shearwater nesting burrows was established for particular habitats on both islands by means of a nearest neighbour analysis. Areas of Pisonia grandis forest had the highest burrow density and near-random distribution patterns for burrows while the island fringes had the lowest densities and higher degrees of aggregation. These results may reflect the importance of social communication within a wedge-tailed shearwater colony. Burrows are distributed in patches around the margins of the colony where clear and fringe habitats are represented, but randomly near the centre in Pisonia areas, where sheer numbers may negate the need for further aggregation.     

Urban bound migration and rural investment: the case of Mexico

The authors investigate an agriculturally based policy for improving rural incomes and for retarding the rural-urban migration flow. The production of agricultural goods is characterized by a production function in which output increases with increases in agricultural labor inputs, capital, public infrastructure, land, and technology. Differences among regions in agricultural technology will reflect regional differences in education, the institutionalized form of productive organization, and differences in access to technological information channeled through more technically advanced cities. To pick up the effect of out-migration changes in state agricultural labor supply and upon agricultural output, the state's agricultural out-migration rate is included together with the agricultural labor force. The gross migrant flow between 2 locations is hypothesized to depend upon a set of variables influencing the individual's perception of the economic rate of return to be gained by moving, a set of variables reflecting the individual's propensity to relocate, the labor displacement effects of investments, and the at risk population at 1 location available to migrate. It is also taken into account that individuals differ in their response to information about origin and destination wage differentials and that individuals may or may not perceive a new ecnomic gain from migration but may base the decision on other considerations. Results of a statistical analysis using data from the Mexican census of population for 1960 and 1970 are: 1) size of the rural labor force was negatively associated with agricultural wages, contrary to expectations; 2) small farmers have benefited from the expansion of irrigation in Mexico; and 3) higher urban wages attract migration, and higher growth rate of agricultural income retards rural-urban migration. With respect to the 1950-60 decade both agricultural income and rural out-migration impacts could have been substantial but both the impact on local urban growth and on the rate of in-migration to the primate city would have been slight.
