Sumatran population changes, 1961–80

In the period 1961 and 1980, Sumatra's population increased from nearly 16 to 28 million; a rise of 78%. This population growth was at least 50% faster than the Indonesia national average, and exceeded only by Maluku. Local and intensive demographic and economic analysis is needed to explain fully this rapid demographic increase. Sumatra's abundant resources of tin, bauxite, petroleum, natural gas, forest and agricultural products during the 1960s and 1970s supported these population increases, as well as providing export income to aid other Indonesian areas.

The chief population changes within Sumatra are:

1. Rapid percentage population growth in Lampung, Jambi, Bengkulu, and Riau provinces. However, population numbers increased most in North Sumatra, Lampung, and South Sumatra.

2. At the more detailed, kabupaten scale, Sumatra's 1961–80 population growth was very uneven, ranging from nearly 229% in central Lampung, over 97% in eight other kabupaten, to as little as 21.8% around Lake Toba in upland North Sumatra. Actual or perceived economic opportunities, sizeable migration flows, and high natural increases favoured some areas; resulted in outmigration flows from others.

3. The nineteen municipalities (only seventeen according to some sources for 1961) rose to twenty kotamadya by the mid‐1960s. Collectively, their urban populations increased from less than 2 million in 1961 to 4.25 million in 1980. Medan, in particular, now is the dominant city not only of Sumatra, but also of all Indonesia beyond Java‐Madura. Only Sawahlunto in upland West Sumatra remained almost stagnant through this period.

4. Population densities rose throughout Sumatra, but at greatly different rates. At the kabupaten scale at least seven areas of relatively high population density, plus a few localized urban‐ or resource‐centred areas elswhere, stood out from other, much less densely populated areas.

     

The effect of growth on stable nitrogen isotope ratios in subadult bone collagen

Stable nitrogen isotopes have been used to reconstruct infant feeding practices as nursing infants have elevated δ¹⁵N ratios compared with their mothers. However, infancy is also a time of rapid growth, which may alter nitrogen isotope diet‐to‐tissue spacing. Several studies have documented a decrease in δ¹⁵N during growth in tissues with relatively fast accretion rates. This study investigates the effect that the growth of long bones, via collagen accretion, has on δ¹⁵N ratios. Long bones from individuals aged seven to nineteen years were obtained from a protohistoric ossuary in Ontario, Canada. Analysis of juveniles and adolescents permitted the examination of growth in a group who were not also nursing. It is concluded that a nitrogen isotope growth effect is not detectable in bone collagen from juveniles and adolescents, because: (1) δ¹⁵N ratios are not significantly different among the epiphyses, metaphyses and diaphysis of a growing long bone; (2) δ¹⁵N ratios are not significantly different between faster‐growing versus slower‐growing metaphyses; and (3) δ¹⁵N ratios are not significantly different between bones (or areas of a bone) that are still undergoing growth, versus bones that have ceased growing. The relatively slow speed of collagen accretion may explain why a growth effect is not manifested. Ultimately this research lends support to the use of nitrogen isotopes from bone collagen for infant feeding reconstructions. Copyright © 2009 John Wiley & Sons, Ltd.     

Retracted: A Possible Case of Hypopituitarism in Neolithic China

A human skeleton with a possible case of hypopituitarism is reported. The individual (burial M53) is from the site of Guanjia, a Neolithic settlement in northern China, dated to the Late Yangshao period (6000–5500 bp ). On the basis of the fully erupted third permanent molars and moderate occlusal dental wear resulting in substantial exposure of dentine, the initially estimated age‐at‐death was placed between 26 and 33 years. However, dimensions of the postcranial skeleton fall significantly below and outside the range from contemporaneous adult populations, and along with delayed epiphyseal fusion present throughout the skeleton, the postcranial age is concordant to that of an 11‐ to 13‐year‐old child. Most long bone epiphyses display incomplete fusion or are entirely unfused, but a lack of microporosity in the metaphyseal areas near growth plates indicates a cessation of longitudinal bone growth. Because no signs of porotic hyperostosis, cribra orbitalia, periosteal lesions or linear enamel hypoplasia are observed, the restricted growth of this individual is likely caused by a growth hormone disorder and is unrelated to nutritional deficiencies or systemic infection.

The Dendroecological Potential of Eucalyptus Camaldulensis Dehnhardt (River Red Gum) from the Barmah Forest,Victoria, Australia

The study of tree rings has been used for over 100 years to inform climatic and geomorphological reconstructions. In mainland Australia, no tree species are currently recognised as providing reliable sources for such studies over extensive areas. Eucalyptus camaldulensis is a widely growing species with a growth pattern that is closely linked to high levels of available moisture, such as that associated with floods. The species therefore has the potential to provide palaeoclimatic information that may be of use in hydrological and geomorphological studies. This study initially examines the microstructure of samples of E. camaldulensis taken from the Barmah Forest to assess the applicability of the species to dendroecological investigation. It is found that samples of the species exhibit ring‐like structures, although there are areas of the samples that contain zones of growth without clear ring boundaries. The patterns of growth rings and zones are found to be common to many trees at a site, although the level of variability of pattern from tree to tree is high. Options for future development of the approach described here are to combine ring studies with isotopic‐based analysis to provide a combination of tree age and climatic history.     

Limits of incremental growth in seasonality studies: The example of the clariid pectoral spines from the Byzantino-Islamic site of Apamea (Syria; sixth to seventh century AD)

An evaluation is given of the value for seasonality studies of incremental growth in the pectoral spines of the Nile catfish Clarias gariepinus. The subfossil spines used for this study are from a Byzantino-Islamic site in Syria, and probably all derive from animals captured on the floodplain during the yearly inundation of the nearby Orontes river, although only 45 per cent of the spines could be recognized as deriving from fish captured during that period. It is believed that the inability to date accurately the season of capture of the other specimens is due to disadvantages inherent in the growth cycle of the fish. For the moment it is possible to determine the season of death only of individuals that were taken during a period of rapid growth.     

THE EFFECT OF LAND‐USE CONTROLS ON THE SPATIAL SIZE OF U.S. URBANIZED AREAS*

ABSTRACT On a sample of U.S. urbanized areas in 2000, we test theoretical hypotheses of the effect of land‐use controls on the spatial size of urban areas. We find that minimum lot‐size zoning and maximum FAR restrictions expand the urban area, while maximum lot‐size zoning, urban growth boundaries, minimum square footage limits, maximum building permit restrictions, minimum person per room controls, and impact fees contract the urban area. All of these findings are consistent with theoretical predictions although the effect of urban growth boundaries and minimum square footage limits are not statistically significant.     

SOVIET POPULATION CHANGE AND CITY GROWTH 1970-79: A PRELIMINARY REPORT

The total, urban and rural population of major civil divisions of the Soviet Union and the population of cities over 100,000 are analyzed and mapped on the basis of preliminary results of the 1979 census. Total population growth rates declined during the 1970–79 intercensal period compared with the 1959–70 period while urbanization continued apace, although unevenly on a regional basis. The Slavic and other western republics, which show the highest urbanization levels of 60 percent and more, were also characterized by the lowest overall growth rates of 6 to 8 percent. Rural population declined almost everywhere outside a southwestern belt of high growth extending from parts of the southern Ukraine through Transcaucasia to Central Asia. Among large cities, moderate growth continues among cities with a multifunctional economy; high rates are evident in cities with major current industrial projects (automotive, for example) and in oil production regions; low rates are typical of some coal-mining and steelmaking centers. (For another report on the 1979 census, see “News Notes,” Soviet Geography, September 1979.)     

Job polarization in the new economy in Danish cities: location,size, and the role of the public sector

ABSTRACT

In this paper we examine the geographic patterns of employment growth and employment polarization in small and medium-sized cities (SMCs) in Denmark during the rise of the new economy. The geography of employment polarization in Danish cities is examined using register-based employment data on occupations and wages divided into the public and private sectors in the period 1993–2006; it therefore covers a long period of transformation and growth in the Danish economy. We conclude that employment growth is characterized by employment polarization combined with growth in low- and high-wage employment and a decline in medium-wage employment. However, these patterns of polarization differ across the public and private sectors, as well as by geography. While local labour market (LLM) size, city position and city specialization influence the geography of private-sector employment growth and polarization, municipal population and composition influence the geography of public-sector growth patterns across wage levels. Finally, public and private employment are positively associated within SMCs, predominantly driven by the positive association between public employment and private-sector low-wage employment. However, public employment is not associated with an increase in private low-wage employment in more remote areas.     

Siena in the early Middle Ages: new data from the excavation at Santa Maria della Scala

The data from excavations around the hospital of Santa Maria in Siena help to build a picture of the city in the early Middle Ages. Comparison is made with the rural site of Montarrenti, and significant differences between the economic development in the town and country are observed, although both suffered decline. Settlement, and economic activity in the city of Siena are seen to go into recession in the post‐Roman period, but signs of growth become visible from the ninth century onwards.     

On the Additions to the Collection of National Antiquities in the British Museum

The evidence for prehistoric occupation in the area of the modern City of London is re-assessed. Two myths surrounding the city's prehistory are examined: a literary myth of a glorious Trojan past and a modern archaeological myth of the absence of prehistory. Having drawn a ‘traditional’ distribution map of prehistoric artefacts, the authors attempted to improve its reliability by quantifying the impact of Roman groundworks on the surviving prehistoric deposits. Topographic models of the area in prehistory and in the Roman period were drawn, and the methodology of the interpolation is discussed. The relative value of in situ, residual and stray finds are considered in the light of this new information. While there is good evidence for Late Bronze Age occupation in the City, the evidence for Neolithic activity is considered to be heavily skewed by Roman activity. The data are used to suggest areas of the City where there is particularly good potential for the survival of prehistoric deposits. The City provides a case study for analysing prehistoric material in a ‘difficult’, deeply stratified, urban context more associated with Roman and medieval archaeology.     

Prehistoric shell beads on the Georgia coast

ABSTRACT

The prehistoric peoples living along the Georgia coast fabricated and used shell beads for millennia. Out of a number of mollusk species inhabiting the region, only a few were selected for the fabrication of beads. The knobbed whelk (Busycon carica) was the most common species used, and it represents the most common whelk found in Atlantic coastal waters. The lightning whelk (Busycon sinistrum), the second most common whelk in the region, was occasionally used in the production of beads. Small numbers of beads were made from marginella and olive shells and, rarely, from bivalve species. Small beads were manufactured from the body whorl of whelks, while larger beads were fabricated from whelk collumella. Shell beads appear in small quantities in Late Archaic period contexts, and then almost disappear during the Woodland period. Beads reappear in quantities at about AD 800 in the Early Mississippian period. More shell beads have been recovered from Mississippian period archaeological contexts along the northern Georgia coast than along the southern coast, reflective of cultural differences between these two geographic areas in the post-Woodland period era.     

THE PRIORITY OF LARGE CITIES IN ZIPF RANK-SIZE RULE SYSTEMS

The author seeks to establish possible reasons for differences in the rates of growth of towns within urban systems with rank-size regularities. It is shown that a system follows Zipf s law if the growth of population N _i of the towns of the system follows the regularity M(ΔN _i )/N _i ～ (In N _i - c) where M is the mathematical expectation, ΔN _i is an increment of Ni over a short period of time, ～ stands for “directly proportional,” and c is a constant.     

Currents and trends in the archaeological sciences

Here I use ISI Web of Knowledge to build on a recent paper by Butzer (2009) and track current trends in the archaeological sciences. I researched eight thematic keywords replete in the title, abstract, keywords and main body of archaeological science literature for the period 1970–2008. For all keywords investigated a steady rise in archaeological science research is evidenced after 1980, with pronounced growth occurring after 2000. I attribute this pattern to the standardisation of research production and academic evaluation, in addition to the democratisation of new information technologies, notably the Internet. The evolution of 10 leading archaeological science journals was also tracked. Since the 1970s, the bibliometric data show that nine of the ten journals have successfully expanded on an annual basis. I found that the biggest growers (the Journal of Archaeological Science [JAS], the Journal of Human Evolution and the Journal of Anthropological Archaeology) are all published by Elsevier. In 2008, the JAS was ranked first for five of the eight thematic keywords by ISI, underlining the popularity and interdisciplinary scope of the journal. According to the 2008 Journal Citation Reports, the JAS ranks second for total citations (4219) in archaeological science and third for its overall impact factor (1.779).     

The Southern Pennine Mesolithic and the ecological record

Arehaeological, palaeoecological, ethnographic and land management evidence is presented which supports the hypothesis of regular and recurrent burning by mesolithic hunting populations in the southern Pennine uplands over a c. 4000-year period. It is suggested that this burning of the upland vegetation led to a permanent suppression of a closed tree cover over large areas above c. 350 m altitude.     

Early Cotswold woodland

Many “wold” names are derived from the OE wald, meaning “woodland”. In a recent paper Everitt examined the evidence for Kent and suggested that areas of wold downland had been wooded in the Anglo-Saxon period. They had also been territorially linked to river-estates as areas of outlying wood-pasture. The present paper examines the evidence for the Cotswolds. Here the name “wold” is applied to an area which was largely open pasture by the medieval period and the use of the term in its later sense of “high, open country” would not have been out of place. Yet the evidence from early place-names and pre-Conquest charters suggests that a great deal of woodland was present in the Anglo-Saxon period, especially in the valleys dissecting the escarpment and along the scarp face. Although this was a watershed area, divided between adjacent valley-based estates, as in Kent, there is little direct evidence here of an early interest in woodland-pasture. The importance of the area seems to have arisen in the middle and later Anglo-Saxon period as a result of an increased use of the upland for sheep pasture. Nevertheless, the term “wold” seems to date from an earlier period when woodland was indeed extensive.     

Economic growth and restructuring in Canada's heartland and hinterland: From shift‐share to multifactor partitioning

The geography of the Canadian economy has long been dominated by heartland‐hinterland contrasts, with manufacturing identified as the dominant function of most heartland cities in analyses of the 1961 and 1971 census data. However, the proportion of employment in manufacturing has been declining in the heartland provinces of Ontario and Quebec over the past fifty years and some geographers argue that the heartland‐hinterland dimension of the regional economy is being overridden by city‐regions that are integrated into global networks of production and trade. The heartland‐hinterland trends are examined using multifactor partitioning (MFP), an advanced shift‐share methodology, for the period of 2001–2006. This is the first intercensal period in which Canadian business has faced the full impact of the removal of North American tariff protection and the increased globalization of the Canadian economy. The data covers employment by eighteen industry sectors for the seventy‐three economic regions defined by Statistics Canada. MFP measures the region and industry‐mix effects, which are interpreted as in the traditional shift‐share model (though they are derived more accurately) and, in addition, an interaction effect. The results demonstrate that the broad heartland‐hinterland differences in the distribution of population and employment growth are increasing not decreasing and that the hinterland is in fact falling further behind the heartland in employment growth. However the Calgary‐Edmonton corridor and the Lower Mainland of British Columbia are emerging as a western heartland. The population size of cities does affect their rates of employment growth, but so too does their location: the growth of heartland cities is outpacing those in the hinterland. The Appendix provides the equations for two‐variable multifactor partitioning.     

Regional Inequality in the EU: How to Finance Greater Cohesion

After outlining the overall scale and evolution of European Union (EU) public expenditure, this paper examines the mechanisms driving the allocation of Cohesion Policy resources. The analysis reveals the extent to which the outcome of the policy's principle- and formula-driven allocation mechanisms is modified by precedent and politico-economic considerations. In particular it shows that the consequent per capita final financial allocations (the intensity of aid) are greatest not for the poorest areas: up to 84% of EU GDP per head, aid increases as income increases. The analysis also emphasizes the on–off nature of the EU policy. In the light of these results a series of simulations are carried out. Attention is given first to a more economically sensitive treatment of transition regions, whose relative growth results in shifts from one category to another and to a mechanism capable of providing differentiated support to all disadvantaged regional economies. Attention is then given to ways of ensuring that final allocations are inversely proportional to income, and that most aid is concentrated on the most disadvantaged areas (Section 5). In the conclusions attention is paid to guidelines which might apply to the reform of the EU Cohesion Policy.     

Study of the Impact of Urban Development on Surface Temperature Using Remote Sensing in Ho Chi Minh City,Southern Vietnam

Rapid urbanisation and industrialisation have resulted in sharp land cover changes. Urban change not only impacts on land cover but also on urban climate. Land surface and atmospheric modifications due to urbanisation generally lead to a modified thermal climate that is warmer than the surrounding, non-urbanised areas. In this research remote sensing technology was used to evaluate urban growth patterns and its thermal characteristics through mapping impervious surfaces and evaluating thermal infrared images. The case study was carried out in the northern part of Ho Chi Minh City, which has experienced accelerated urban development since the late 1980s. Landsat and Aster images were used to calculate variations in urban impervious surfaces from 1989 to 2006. Thermal bands were processed to obtain radiant surface temperatures for investigating the urban heat island effect associated with increasing impervious surfaces, both spatially and temporally. Impacts of urban development on surface temperature were shown by investigating the surface urban heat island effect intensity. The results show that the built-up area in the northern part of Ho Chi Minh City expanded by 6.5 times between 1989 and 2006. Urban development has altered the magnitude and pattern of the surface urban heat island, with the highest land surface temperature cores found in the industrial (greater than 45^oC) and urban areas (within 36^oC and 40^oC). In suburban and rural areas, where agricultural land still remains with full vegetation cover, the land surface temperature is usually lower. Using remote sensing, the impervious surface was extracted with overall accuracy and a Kappa coefficient for all three years greater than 96%, and the retrieved land surface temperatures with variations from in-situ measurements of less than 2^oC. The results presented here indicate that remote sensing can help to spatially monitor urban development and land surface temperature changes over the whole area and over a long period of time.     

Fremont Hunting and Resource Intensification in the Eastern Great Basin

Empirical tests of resource-intensification models argue for diminishing foraging efficiency among hunter–gatherers in California over the past 2000 years (Basgall, 1987,Research in Economic Anthropology9,21–52; Broughton, 1994aJournal of Archaeological Science21,501–514; 1994bJournal of Anthropological Anthropology13, 371–401). The evidence for this long-term trajectory consists of decreases in the abundance of large, high-ranked prey in archaeofaunal assemblages. This paper presents faunal data from Fremont structural sites in the eastern Great Basin and Northern Colorado Plateau as an additional empirical test of resource intensification patterns and compares them to trends in California and the American Southwest. The measure of resource efficiency used is the artiodactyl index (following Broughton, 1994ab), a tool derived from prey choice models of optimal foraging. Faunal data from Fremont structural sites argue that (1) foraging efficiency declined during the Fremont period, and (2) this decline was due to population growth.
