ABSTRACT We use disaggregated data on Chilean plants, and the Chilean input–output table to examine the impact of agglomeration spillovers on total factor productivity (TFP). In common with previous studies, we find evidence for intraindustry spillovers, but none for general cross‐industry spillovers. This picture changes when we take vertical industry relations into account. There are important productivity spillovers from plants in upstream industries. Interestingly, a similar effect cannot be found from plants in downstream industries. The number of plants in these sectors has no effect on plant‐level TFP, just as the number of plants in other industries that are neither important upstream suppliers nor downstream customers also has no effect. 相似文献

Der letzte Bericht des Intergovernmental Panel on Climate Change (IPCC 2007) erl?utert die weltweiten Auswirkungen des Klimawandels
deutlich – allerdings aus globaler Sicht. Um zu kl?ren wie sich das regionale Klima in ?sterreich ver?ndern wird, wurde mit
dem Projekt „reclip:more“ (Research for Climate Protection: Model Run Evaluation) eine erste kleinr?umige Datenbasis für Klimaschutz
und Klimafolgenforschung für ?sterreich generiert. Klimaszenarien wurden mittels regionaler Klimamodelle (RCMs) für die Alpen
als 10 × 10-Kilometer-Raster und mit anschlie?endem Downscaling für ?sterreich mit einer Zielaufl?sung 1 km entwickelt. Die
RCMs wurden mit ERA-40 Reanalyse-Daten der Vergangenheit und Daten eines Zukunftsszenarios des globalen Klimamodells (GCM)
ECHAM5 angetrieben, um retrospektive (1981 bis 1990) und künftige (2041 bis 2050) Klimadatens?tze für die Alpen zu berechnen
und M?glichkeiten und Unsicherheiten der Modelle und Downscaling-Methoden für die Alpen zu evaluieren. Die nun vorliegenden
Datens?tze und weitere, die im Folgeprojekt „reclip:century“ für alternative Treibhausgasszenarien bis 2100 berechnet werden,
dienen dazu als Basis für Aussagen über ?kologische und sozio?konomische Entwicklungen im Hinblick auf den Klimawandel. 相似文献

Cities are considered to be the major drivers of the global economy for many reasons, including their creative and innovative potential in generating sustainable economic growth. Istanbul is one of the global cities searching for a long-term growth strategy. This paper starts with a modest effort of composing an index to be used in the evaluation of the creative potential of cities. Our proposed index, “global creative index”, consists of five main criteria: (1) creativeness, (2) innovativeness, (3) intellectual development, (4) global network connectivity and (5) world cityness emphasizing multinational corporate economy, international division of labour and high intensity of producer and financial services. The use of the index is illustrated through the comparison of nine cities: Hong Kong, Istanbul, London, Los Angeles, Moscow, New York, Shanghai, Singapore and Toronto. The analysis of these nine cities shows that Istanbul is building an innovation environment, but it still lacks research and development infrastructure, technical support and investment in higher education. This comparison offers guidelines for policy-makers to sketch the growth of Istanbul along the lines of creativity and innovativeness. 相似文献

Two thousand and six hundred fifty years after the death of the “Girl of the Uchter Moor”, it was still possible to secure
good-quality fingerprints from the right hand of this bog body by using photographic methods followed by image enhancement
with an Automated Fingerprint Identification System. A detailed fingerprint analysis was performed, and all five fingers of
“Moora's” right hand exhibited ulnar loops. Even today, this is still the most common fingerprint pattern type in Europe.
It was also possible to find enough minutiae on the right thumb for secure dactyloscopic identification after more than 2,000 years.
The example of “Moora" therefore demonstrates new possibilities for future fingerprint examinations of ancient bodies in archaeological
as well as forensic casework. 相似文献

In this article, we discuss children's becoming as food consumers in the intersection of various foodscapes. We draw from a project, Children as co-researchers of foodscapes, where we have been working with children as co-researchers, using basically ethnographic methods, and as co-designers in a collaborative design effort. This article focuses on the findings from a theoretically inspired perspective, using the concept of foodscapes. These are food-related structures of different kinds, which evolve as the child explores them and where children as food consumers are generated. In this article, we highlight the scapes of taste, routines, people, things, commerce, child (as opposed to adult) and health and give brief accounts of the way the children related to them. Finally, we turn to the benefits of working with foodscapes for a better understanding of children's becoming as food consumers in the intersection of various foodscapes. This article is based on data gathered by the children, but also on our fieldwork notes and observations following the children in their foodscapes. 相似文献

Landscape archaeology, as a type of research based on a systemic surface survey and that results in quantifiable datasets of high quality, has started to be practiced in southeastern Arabia only in recent years. In this paper, I will briefly review the short history of landscape archaeology in the area and its relevance. I will then present the approach and methods used in the Wadi al Jizzi Archaeological Project and discuss some of the results obtained to discuss both the potential and problems of the data that the project generated. In particular, I will focus on ephemeral sites and assemblages, data quality and data representativity. 相似文献

Konggap, sung melodic motifs that last only a few seconds embody the acoustic representation of a person among the Yupno people of Papua New Guinea and are a unique phenomenon in the Pacific. The konggap forms a very complex system of personal identification and expression of social relationships; at the same time it connects the singer to the ancestral world. Every person in Yupno society possesses his or her own konggap, and Yupno people are able to identify a large number of konggap, some men even up to three hundred. Nobody would sing his or her own konggap during the day. When crossing Yupno land, a person has to sing the konggap of the respective landowner to identify himself as an insider, a local person ? unlike strangers (and possible enemies) who remain silent. But at nightly dances each dancer sings his own konggap and during mourning at funerals groups of women simultaneously sing the konggap of the deceased person. An interdisciplinary ethnographic‐musicological‐cognitive fieldwork study was conducted in order to find out how it is possible that the Yupno are able to identify and distinguish between this staggering amount of very short sung motifs. 相似文献
