From the 1970s onwards, the regional development suffers a change in its nature: it becomes more and more endogenous. The transition from a perspective of development from above to a perspective of development from below, and the transition from a problematic of redistribution to a problematic of resources creation, need more than a readjustment of the existing regional theories. It turns out to be necessary to focus on the endogeneization of the development mechanism, i.e. on the interactions leading to transformations and adaptations of localized production systems. In fact, it is a matter of building up theories of change that would be able to explain how a region can generate mechanism of wealth creation from its specific resources. Now, these different processes are closely connected to urban organization and their implementation depends on the milieu (i.e. innovative or non‐innovative).  相似文献

Streamline analyses of mean monthly resultant surface winds over Australia are presented. Mean confluences represent either cyclone trajectories, or modal fronts. These analyses suggest that Australia's annual airstream climate is of two regimes: that of September to March inclusive, and April to August inclusive. The winter half-year is exemplified by a continental airstream source in southern Australia which diverges over virtually the entire continent. It continues into September and October, although dominating only the southern third to half of Australia, and is absent from November to March. During the summer half-year a new pattern emerges, with three maritime air stream sources represented over the continent: first, air from the Southern Ocean penetrates the south coast reaching its furthest northward extension from December to March inclusive; a second source originating over the Pacific Ocean dominates eastern and northern Australia; and a monsoon source originating over the Indian Ocean which flows overland affecting northern Western Australia. Two modal confluences are noted, one over northwestern Australia from November-February separating monsoon flow from that emanating from the east, and another extending from the west central coast east-southeastward to the southeast coast from November-March separating Southern Ocean air from that originating over the Pacific Ocean.  相似文献

Copper isotope ratios differ between hypogene sulfidic, supergene sulfidic and oxidized ore sources. Traditional lead isotope signatures of ancient metals are specific to deposits, while Cu isotope signatures are specific to the types of ore minerals used for metal production in ancient times. Two methodological case studies are presented: First, the mining district of Faynan (Jordan) was investigated. Here, mainly oxidized copper ores occur in the deposits. The production of copper from Fayan’s ore sources is confirmed by the measurement of the Cu isotope signature of ingots from the Early Bronze Age metal workshop from Khirbat Hamra Ifdan. Based on our results illustrating differences in the Cu isotope composition between the ore mineralizations from Timna (Israel) and Faynan, it is now possible to determine these prehistoric mining districts from which copper artifacts originated by combining trace elements and Pb isotopes with Cu isotopes. The second case study presents data on Late Bronze Age copper production in Cyprus. Oxhide ingots from the shipwreck of Uluburun (Turkey) were tested for their lead isotope signatures and assigned to Cypriot deposits in the recent decades. The oxhide ingots from Uluburun show a Cu isotope signature which we also found for oxidized copper ores from Cyprus, while younger oxhide ingots as well as metallurgical slag from the Cypriot settlements Kition and Enkomi show a different signature which might be due to the use of sulfidic ore sources from a greater depth of deposits. We assert that there could be a chronological shift from oxidized to sulfidic ore sources for the copper production in Cyprus, requiring different technologies. Therefore, Cu isotopes can be used as a proxy to reconstruct mining and induced smelting activities in ancient times.  相似文献

Archaeologists working with prey animal bonebeds are interested in determining whether the animals were obtained through a single, mass kill event or instead accumulated over time from multiple hunting events. This is often difficult to determine. The author investigated the use of stable isotope ratio analysis to distinguish accumulations of individuals derived from multiple populations from mass kills of individuals from a single population. Carbon, oxygen and strontium stable isotope ratios were measured in tooth enamel from modern pronghorn (Antilocapra americana) with known mortality circumstances. These ratios were then analyzed using basic statistical methods as well as a scaled distance technique that permits integrated analysis of multiple isotopes and multiple samples, and a bootstrap subsampling approach was used to quantify differences among populations. It appears that, in some circumstances, stable isotope analysis can contribute to distinguishing bonebeds originating as accumulations of individuals derived from multiple populations from mass kills of individuals from a single population. Three-element isotope ratio distance measures provide the best isotopic indicator of pronghorn bonebed population origins, especially when bootstrap subsampling is used to compare to sites of known pronghorn population composition.  相似文献

Limestone outcrops that form a north-south belt approximately 1.4 km long, 15 km east of Manilla and previously referred to as the Uralba Beds, and associated rocks, are shown to be an olistostromal component of the Wisemans Arm Formation. Elongate olistoliths up to 100 m in length are flanked by limestone conglomerate with clasts set in a volcaniclastic matrix derived from a range of volcanic rock types. Volcanic olistoliths, including a mass of ankaramitic basalt, are also present. Conodont faunas of differing ages were obtained from various outcrops. A Late Ordovician (Eastonian, Ea3) fauna of over 400 elements from some outcrops is identical to one recently documented from elsewhere in the Wisemans Arm Formation. A small Early Silurian (late Llandovery-early Wenlock) fauna from four outcrops (including two formerly thought to be Ordovician) comprises the first documented conodont fauna of this age from the New England Fold Belt.  相似文献

The village of Yunosawa, near Kusatsu town, Gunma Prefecture, Japan, existed as a refuge for Hansen's disease sufferers from 1887 to 1941. It was the only such place to maintain, to its final closure, self-government free from the pre-war State isolation policy.The aim of this study is to clarify the dynamism from the notion of "the protection from social persecution of leprosy patients" to the notion of "the defense of society from the leprosy patients as a source of infection". Herein, I will explain history of Yunosawa village and its relation to the shift in State policy concerning leprosy. In addition, I will demonstrate the value of a free medical-treatment area.  相似文献

Korea witnessed a large increase in the fraction of men marrying spouses from Southeast Asia. In the 1990s, about one per cent of Korean men’s new marriages were to Southeast Asian women but by 2005, this increased to over nine per cent with even higher rates in rural areas. With the use of a logit model and Marriage Register data from 1993–2013, the determinants of international marriages are explored using a more rigorous approach and over a longer period of observation compared to previous studies. Older Korean men with lower socioeconomic status were more likely to marry a woman from Southeast Asia (compared to a fellow Korean). The predictors of international marriage differed depending on the wife’s birth country: if the wife had some college education there was a higher probability of marriage to a Filipino woman, but less likely to a woman from China or Vietnam, compared to marriage to a Korean woman. Finally, over the past two decades the education level, age at marriage, and country of origin of the foreign wives have changed substantially. The data shows fewer women migrating from China (of which about 70% are ethnically Korean), and a rising number from Vietnam. This ‘marriage migration’ has implications for the demographics, ethnicity, and occupational composition of those living in Korea.  相似文献

The Mesolithic–Neolithic transition in north-west Europe has been described as rapid and uniform, entailing a swift shift from the use of marine and other wild resources to domesticated terrestrial resources. Here, we approach the when, what and how of this transition on a regional level, using empirical data from Öland, an island in the Baltic Sea off the Swedish east coast, and also monitor changes that occurred after the shift. Radiocarbon dating and stable carbon and nitrogen isotope analyses of bones and teeth from 123 human individuals, along with faunal isotope data from 27 species, applying to nine sites on Öland and covering a time span from the Mesolithic to the Roman Period, demonstrate a great diversity in food practices, mainly governed by culture and independent of climatic changes. There was a marked dietary shift during the second half of the third millennium from a mixed marine diet to the use of exclusively terrestrial resources, interpreted as marking the large-scale introduction of farming. Contrary to previous claims, this took place at the end of the Neolithic and not at the onset. Our data also show that culturally induced dietary transitions occurred continuously throughout prehistory. The availability of high-resolution data on various levels, from intra-individual to inter-population, makes stable isotope analysis a powerful tool for studying the evolution of food practices.  相似文献

This paper presents and interprets two data sets from Vestfold, Southeast Norway: the pollen record is from a small lake basin, isolated from the sea in Mid Mesolithic (8100–6400 cal BC), and with a record of sediment deposition up to recent time. Charred plant remains from six settlement sites ranging in date from the Late Neolithic (2400–1800 cal BC) to the Merovingian Period (cal AD 570–800). Soil from archaeological contexts that was recovered from several prehistoric settlement features (two- and three-aisled houses, a rock shelter and a pit) has also been investigated. The number and concentrations of identifiable charred macro remains are low from all features except one, but the records contribute to the interpretation of agriculture and wild plant use. Carbonised cereals dated to the Late Neolithic/Early Bronze Age are reported from a two-aisled house. Naked barley was the main cereal identified and a few weed seeds were found with the cereal grains. In a rock shelter nearby, cereals and seeds of flax were found, demonstrating cultivation in the Late Bronze Age. Pollen of ribwort plantain recorded in lake deposits in Nordbytjern, 0·5?km to the southwest, also indicates agricultural activity in the southern part of Vestfold during the Late Bronze Age. Archaeobotanical samples from Early Iron Age houses contained low concentrations of carbonised cereal remains, mainly hulled barley, but also wheat and oat. Seeds/fruits of weeds, plants of moist/wet habitats and grasses increase in abundance from the end of Roman Period. The high concentration of hulled barley found in a pit at the site of Ringdal 13 confirms that hulled barley was a cereal used in the Iron Age. Throughout the Iron Age, cereal pollen has a continuous curve in the Nordbytjern pollen diagram, demonstrating the significance of cereal cultivation in Vestfold. Flax was also cultivated in the vicinity of and probably processed in Nordbytjern. Large numbers of rush seeds and sedge nutlets indicate a possible involvement in basketry and cordage making and/or as animal fodder.  相似文献

A popular approach to examining the effects of public policy has been to rely on a spatial data sample of border counties as in Holmes (1998)—border counties from a sample of states that are used in conjunction with least‐squares estimation techniques in an attempt to isolate the policy impact while controlling for spatial dependence that often arises from latent or unobserved variables. This technique is in the spirit of control‐group methodologies from the laboratory sciences. This paper contrasts border‐county estimation results from Holmes' (1998) approach and those from a related methodology set forth in Holcombe and Lacombe (2003), with estimates from a spatial autoregressive model explicitly accounting for within‐state and between‐state public policy effects. As an illustration, the paper examines the effects of Aid to Families with Dependent Children (AFDC) and Food Stamp payments on female‐headed households and female labor force participation using the three different methods.  相似文献

Ulúa marble vases from the Ulúa Valley of northwestern Honduras are a hallmark luxury good from Late Classic (ad 600–900) Mesoamerica. Archaeological and stylistic data point to centralized production at one site, Travesía. This paper analyses stable isotope and petrographic data from the vases and three potential procurement areas. The results indicate that the vases were produced from one primary source with one, potentially two, secondary sources. Procurement patterns most probably corresponded to contemporary communication routes. The results clearly indicate that a multi‐method approach is necessary for sourcing marble from Honduras.  相似文献

The domesticated Red Jungle-fowl G. gallus is believed to have been dispersed by man from India during the Holocene. The distal end of a radius from the Ipswichian Interglacial deposits at Crayford, Kent, was indistinguishable from that of the wild form of Red Jungle-folw. A coracoid from the early Middle Pleistocene of N Norfolk was also very similar to that species but showed differences comparable with those found between different species of Gallus. At least one species referable to Gallus is known from the Pliocene of South-eastern Europe. Extrapolating from zoogeographical speciation patterns it would be possible for a Gallus species to have evolved through Pleistocene speciation in the European region. The species might have become extinct during a glaciation or have been exterminated by early man. A new species Gallus europaeus is described with the coracoid as a holotype, and the radius from Kent is tentatively referred to it.  相似文献

Archaeological cobs free of mineral contaminants should be used to source the soils in which they were grown. Mineral contaminants often contain much higher concentrations of metals than vegetal materials and can alter a cob’s apparent metal and heavy-isotope content. Cleaning a cob via immersion in an acid solution for more than a few minutes will result in the incongruent and sometimes complete leaching of metals, including strontium (Sr), from the cob. When using 87Sr/86Sr to determine the location of potential agriculture fields, it is best to either integrate several depth-integrated soil samples or to integrate several vegetation samples from individual fields. Biologically labile Sr in semi-arid Southwestern soils largely originates from eolian source or sources and usually is not derived from underlying bedrock. Existing Sr-isotope data indicate that archaeological cobs from Aztec Ruins came from either the Mesa Verde-McElmo Dome or Totah areas, that Pueblo Bonito and Chetro Ketl cobs, from Chaco Canyon that predate A.D. 1130, probably came from the Rio Chaco corridor, and that cobs from Chaco Canyon, that postdate A.D. 1130, probably came from either the Totah or Zuni areas.  相似文献

Using longitudinal data from Jiangsu Fertility Intention and Behaviour Study (JFIBS) from year 2007 and 2010, this study analyses the fertility intention and behaviour of women who are qualified to have two children from a psychosocial point of view. Based on the Theory of Planned Behaviour, the theoretical framework from fertility intention to fertility behaviour is reconstructed. By observing the phenomenon from the micro-level, the gap between female fertility intention and behaviour and its associated factors are studied. The result shows that, given the situation of being qualified to have two children according to the government's birth control policy, when faced with the choice of whether to have a second child or not, people tend to make their decisions rationally. Attitudes towards fertility, subjective norms, and perceived behaviour control all contribute significantly to the discrepancy between fertility intention and behaviour. In addition, the formation of a concrete birth plan is a major driving force for translating fertility intention into action.  相似文献

In the present series we have dated two samples from a previously unknown pilework E. of the Kastelholm castle, two other logs from old layers to the S. of the castle, two charcoal samples from a layer E. of the castle, four samples of various materials from a ditch SE of the castle, and one sample from outside the NE part of the castle. All the samples were carefully pre‐treated, δ13C normalization performed and the measurements extended to reach a statistical uncertainty of usually less than ±60 years. The results are given in radiocarbon years and calibrated.  相似文献

Genetic data from archaeological specimens provides a potent new approach for addressing questions in prehistory. Hair from archaeological sites is an important but overlooked data source amenable to molecular analysis. To date DNA identification from hair is limited to modern samples. Our study is the first to report DNA recovery from a 9800-year-old specimen. We report methods used to extract mitochondrial DNA and obtain accelerator mass spectrometry radiocarbon dates (AMS-14C) from hairs plucked from a piece of ancient bighorn sheep (Ovis canadensis nelsoni) skin found at Smith Creek Cave, Nevada. The ability to obtain reliable radiocarbon dates and DNA sequences from single ancient hairs opens new possibilities for addressing biological questions in prehistory.  相似文献

The water requirements of the Moscow region, now estimated at 6 cubic kilometers a year, are expected to increase by a factor of 2.5 to 3 over the long term in connection with higher water use rates for households and municipal uses, industrial expansion and the proposed development of perennial pasture lands for livestock. Over the short term, Moscow's additional needs are to be met from two major sources: (a) additional transfer of water from the Ivan'kovo Reservoir on the Volga River north of Moscow; (b) development of a water-transfer system from the Ugra River (a left tributary of the Oka River), southwest of Moscow. Over the long term, the region's water resources may have to be replenished from Lake Ladoga or from the Volga River's Rybinsk Reservoir, which may by then also be receiving additional water from northern streams.  相似文献

A concentration of fish remains found in a single room of a fortified building at Mleiha (United Arab Emirates) is presented here. Part of it was probably the filling of a bag or an organic container that fell from a bench onto the floor of the room. The various species recovered from these contexts, dating to the second to mid‐third centuries AD, are briefly described. Particular attention is paid to the skeletal elements by which the fish are represented and to the corresponding lengths of the animals, as these allow the proposition that the fish had been dried on the seashore before being carried to the site inland. The data from building H will be compared to those from previously studied contexts at Mleiha (Gautier & Van Neer 1999 ; Mashkour & Van Neer 1999 ). In addition the ichthyofauna from ed‐Dur (Van Neer & Gautier 1993 ), a coastal site that is partially contemporaneous with the contexts from building H, will be considered.  相似文献
