A region's technology potential can be developed in three ways: public finding; private investment (by business); and an intermediate area which ensures coherence between the public and private sectors, and which is mainly to be seen in interface structures between universities and business. After presenting these ways for Rhône‐Alpes, the paper introduces the regional policy to promote science and technology. According to French centralized political structure, the regional government acts as a lever. The region's innovation‐oriented policy, which should not be confused with a research‐oriented policy, has the impact of aiming all action at improving the technological environment of business, and at facilitating their economic development by integrating new technologies. Similarities between Rhône‐Alpes and Baden‐Würtemberg have led these two regions to cooperate increasingly in the fields of science and technology. The ‘four motor‐regions for Europe’ (with Lombardia and Catalonia) experiment in the field of new‐material investment cooperation could be useful if we think of the process aimed at strengthening integration in the European Community.  相似文献

Abstract: In this article we attempt to “seize back the creative initiative” to uncover whether poetry might be a useful postcolonial research method. In exploring the possibilities and limitations of poetry as a means of re‐representing and interpreting data collected through in‐depth qualitative interviews, our conclusions are ambivalent: we are attracted to poetry but troubled by it too. For instance, poetry does hold promise through its ability to imaginatively project thoughts and ideas, opening up space so new perspectives can emerge. However, as academics we are always complicit in the knowledge creation process (albeit to varying degrees), and so the representative qualities of poetry are never unproblematic or straightforward. Thus although poetry does have potential as a method for postcolonial geography research, we are making a cautious and careful appeal for its use. We use the case of ecotourism research conducted in Boabeng‐Fiema Monkey Sanctuary in Ghana to explore these ideas.  相似文献

This study presents a method for predicting meagre (Argyrosomus regius) body size (total length) from otoliths and vertebrae recovered from archaeological sites. The method involves regression equations calculated from a reference collection of 36 meagre skeletons and 113 meagre otoliths (sagitta) and allows the simultaneous estimation of original body size and minimum number of individuals (MNI) from archaeological bone structures. We selected the following measurements to predict meagre body size: greatest dorso-ventral height, greatest mediolateral breadth, and greatest anteroposterior length of the vertebrae centra; maximum anteroposterior length, medial anteroposterior length, and dorso-ventral height of the sagitta. Our results show that the original body size of meagre can be accurately predicted from many bone measurements (r2 range: 0.921–0.992). We exemplify the use of the regressions in the assessment of size variation and MNI of meagre from four Portuguese Mesolithic sites. We show that regression results provide additional insight into the significant role that this fish played in the subsistence of coastal fisher-hunter-gatherers, who targeted medium-sized animals but were also capable of acquiring rather larger specimens.  相似文献

ABSTRACT In research conducted some 20 years ago, we elucidated the starkly lower suburbanization propensities of black households in the Washington, D.C. metropolitan area. The paper showed that simulated closure of large socio‐economic gaps between blacks and whites did little to diminish prevailing high levels of residential segregation or otherwise enhance moves by black households to areas of educational, employment, and housing opportunity. Some two decades later and in the wake of significant urban evolution, this paper assesses anew racial variations in residential location choice. Results of the multinomial logit (MNL) analysis indicate large, persistent racial differentials in intrametropolitan residential location choice. While black location choice in 2000 was relatively more dispersed than in 1980, it remained remarkably concentrated in D.C. and Prince George's County. As in our prior analysis, results showed that large simulated gains in black economic and educational status had little effect on prevailing racial segregation. These findings underscore the ongoing, limited access of black households to schooling, employment, and homeownership opportunities available outside traditional areas of settlement. In marked contrast, the locational choices of Latino and immigrant households bore greater similarity to those of whites and were more sensitive to improvements in socio‐economic status.  相似文献

Ferrari, M., El-Hedeny, M., Zakhera, M., El-Sabbagh, A. & Al Farraj, S., May 2018. Middle?Upper Jurassic marine gastropods from central Saudi Arabia. Alcheringa.

A total of 68 gastropod specimens are reported from the Middle?Upper Jurassic sedimentary successions exposed at central Saudi Arabia. The studied material comes from the Tuwaiq Mountain and Hanifa formations at the Khashm al Qaddiyah, Dirab, Jabal al Abakkayn and Maáshabah sections. Thirteen species are identified, described and illustrated. Among them, a new Aporrhais species (A. sauditica sp. nov.) is introduced. In addition, two further possible new Pseudomelania species from the same strata are mentioned. Other members of the assemblage include Kosmomphalus? sp. aff. K. reticulatus Fischer, Bourguetia? sp. aff. B. saemanni (Oppel), Bourguetia? sp., Ampullospira sp., Globularia? sp. cf. G. bajociana Fischer, Purpuroidea sp. aff. P. glabra Morris and Lycett, Purpuroidea sp., Cossmannea sp. aff. C. desvoidyi (d’Orbigny), Cryptoplocus sp. aff. C. depressus (Voltz) and Actaeonina? sp. Stratigraphically, seven species of this gastropod assemblage were only reported from the Middle Jurassic, whereas the other six ones are extending from the Middle to the Upper Jurassic of the studied succession. As compared with their gastropod content, the Khashm al Qaddiyah represents the richest section (33 out of 68 specimens, 48.5%), whereas the Maáshabah section showed an impoverished gastropod assemblage (only three specimens, 4.4%). The species reported here show paleobiogeographical affinities with coeval gastropod assemblages from India, east Africa, Middle East (Israel, the Sinai of Egypt) and western Tethys. The identified species confirm three depositional settings: open shelf lagoon, shoal/fore-shoal and open marine environments. The lower degree of fragmentation, poor sorting and scarcity of abrasion indicate a parautochthonous faunal assemblage.
