Recognized as one of the most unique archaeological sites in the world, the Giza pyramids plateau is the location of the three great pyramids and the Sphinx, tombs, seven smaller pyramids, and other monuments. Over the centuries the plateau has been instrumental in introducing Egyptian civilization to the world, and was recently declared as one of the most iconic travel spots on the planet.In recent years, the location of the new Grand Egyptian Museum (GEM) within the site of the plateau re-ignited the debate between scholars, practitioners and activists over development activities within and around this unique site. Consequently, a growing conflict re-emerged between conserving the plateau and developing the surrounding areas. Additionally, this invaluable site is threatened by urban expansion and development, pollution, rising groundwater and extensive tourism. Yet, currently there are neither tourism management nor development plans for the site.Building on national and international conservation conventions and charters, this paper explores analyses and documents the current gap between ideal conservation management sittings within and around the pyramids plateau and the reality of urban development trends and tourism activities. 相似文献

The ideas of ‘nation’, ‘national security’ and ‘development’ have played havoc with South Asian cultures. The notion of ‘nation state’ has tended to reproduce aspirations of the majority people who are often reconstructed by alien categories and leads to the alienation of minority communities. Virtually all ethnic conflicts in South Asia have their roots in this idea. A more viable and desirable future for South Asia lies in rethinking the model of development and reinventing the notions of state and security. 相似文献

Natural resource scarcity has been making a resurgence as a dominant theme in recent economic writings. Most of the papers on this subject, however, have been narrow in their scope— discussing the issue mainly from a specific viewpoint or ideological stand. This paper attempts to give a balanced treatment to three economic positions (the traditionalist, the revisionist, and the unorthodox economist) taken toward natural resource scarcity. As such, the main objective of the paper is to present and analyze the basic arguments that have been advanced by the proponents of these three positions. It is the author's intent that this approach will help clarify the main factors that have been the source of disagreements among economists over the probable causes and ramifications of societal problems emanating from scarcity and in so doing provide a clearer perspective for prudent action. 相似文献

L'hypothèse de la distribution normale lors de l'analyse des données, permet entre autres, l'utilisation des tests statistiques classiques, ce que n'autorise pas une distribution asymétrique ou aplatie au centre et allongée awe extrémités. Ce travails'adresseprécisé-ment à la forme de la distribution des résidus quotidiens dans le cas d'évènements simultanés, e'est-d̀-dire ceux affectant un certain nombre d'entreprises au mǐme moment, puisque aucune étude ne s'est préoccuppée, à notre connaissance, de ce phénomène. Nos résultats semblent indiquer que les hypothèses de la distribution normale et de non-aplatissement des résidus quotidiens dans le cas d'événements simultanés sont irréalistes, le sort de l'hypothèse d'asymétrie ne semblepas clair surtout à un intervalle de condiance de 99 pourcent. L'utilité des tests statistiques classiques se trouve, par conséquent, très minimisée. Ces tests auront, en effet, tendance à rejeter l'hypothèse de performance normale mǐme en l'absence de toute performance anormale. Abstract The hypothesis of normal distribution in the analysis of data permits, among other things, the use of classical statistical tests. This is not allowed by a distribution which is asymetric or flat at the center and extended at the extremities. This paper deals specifically with the shape of the distribution of daily remainders in the case of simultaneous events which affect a number of businesses at the same time because, to our knowledge, no study has previously dealt with this phenomenon. Our results seem to indicate that the hypothesis of normal distribution and of the non-flattening of daily remainders in the case of simultaneous events are unrealistic and the outcome of hypothesis of asymetry does not seem clear especially at a 99% confidence interval. As a result, the use of classical statistical tests is minimized. In effect, these tests will generally reject the hypothesis of normal performance even in the absence of any abnormal performance. 相似文献

Conventional estimates of the economic return to agricultural research use market prices for the values of products and inputs; on this basis, economic rates of return are typically well above the cost of capital, suggesting that more investment in research would be socially desirable. But these estimates may be incorrect if, as is often the case, market prices are distorted by market failures or government policies and hence do not reflect social values. This paper presents a simple, partial-equilibrium methodology with which to improve the measurement of social returns to research by taking account of multiple distortions in the market prices of products, inputs and foreign exchange. The method also takes account of variation in domestic and world prices, making a product tradable in some years and nontradable in others. The method is applied to the case of Hageen-Dura 1 (HD-1), Sub-Saharan Africa's first commercially successful hybrid sorghum. HD-1 was released in the Sudan in 1983. From the start of research in 1979 to 1992, the HD-1 breeding program had an estimated IRR of 97% when all major policies in the sorghum market, the fertilizer market, and the exchange rate are taken into account. The high rate of return to HD-1 research was due to the program's low cost and rapid payoff, pointing to the potential value of small adaptive research programs, taking full advantage of foreign technology and genetic material to produce locally-appropriate crosses in a short period of time. Even in the highly distorted economies of Africa, such programs can yield very high payoffs. 相似文献

This study examined the international differences in reporting and disclosure adequacy and relates these differences to the economic and political environment of each country. The main hypothesis was that the reporting and disclosure adequacy is likely to differ with differences in the political, economic and demographic environment from different countries. While the results were not significant the paper indicates the need for research in a relatively unexplored area. 相似文献

In this experiment, alternative disclosures of socio-economic accounting information, namely the abatement costs of pollution, were investigated as accounting techniques which may influence the investment decision of potential users. The theoretical rationale stemming from the linguistic relativity paradigm in accounting was that in general the accounting techniques may tend to facilitate or render more difficult various (nonlinguistic) managerial behaviors on the part of the users, and that in this particular context the investment decision effects from different professional groups using alternative socio-economic information will be different. The findings attest to the general relevance of socio-economic accounting information for the bankers under any investment strategy, and for the accountants only under an investment strategy focusing on capital gains. 相似文献
