This paper is concerned with a methodology that is able to recognize and classify geometric shapes, in particular urban shapes. The main objective of this study is to develop a shape index that will address Whyte's category of “spatial form” (1968), that is, the external appearance or outward form, in contrast with the “internal form,” which is the structural form. We first review methodologies of shape recognition and classification. Next, we propose a viable formulation for such an endeavor by drawing from the aforementioned methodologies, and we aim to overcome some of their limitations by formulating a new index. We will apply the resulting shape index to an illustrative case in order to recognize urban shapes.  相似文献

The expansion of protected areas (PAs) is feared to negatively affect the local economy, as every PA, albeit to different degrees, entails restriction to the economic activities. The literature on the topic has started assessing what is the socioeconomic impact of PAs, mostly focusing on the Global South. The objective of this article is the analysis of the socioeconomic impact of three Italian national parks (NPs), established in the 2000s, using a counterfactual approach based on both the outcome regression diff-in-diff and the doubly robust diff-in-diff combined with different propensity score-based and Mahalanobis distance matching procedures. We find that the three Italian NPs have a robust and statistically significant impact on average income of residents in municipalities hosting them. Conversely, there is weak evidence that population and local establishments are positively affected, and touristic local establishments and employment are negatively affected by the three NPs. All together the results indicate that the three NPs have no negative effect on the socioeconomic dynamics of the territories impacted, although additional investigations are required to shed lights to the impact mechanisms.  相似文献

Effective and optimized e‐government in Egypt faces daunting challenges that are less technical in nature and more over the issues of institutional resistance and of political will. A review of the state of e‐government in Egypt is presented with analysis focusing on the state of service implementation in 2012. The points of discussion on e‐government covered here include:
  • E‐subjugation in the guise of e‐government via information control and cyber‐snooping;
  • Institutional resistance to the transformation of routine functions into automated systems;
  • Institutional resistance to transparency of government operations;
  • Analysis of the state of Egyptian ministry websites on six dimensions of e‐government development;
  • Discussion on implementation of Egypt's e‐government master plan;
  • Commentary on the revolutionary potential of e‐government augmented by vision, competence, and leadership; and
  • Caveats that are important to note in moving the vision of e‐governance from concept to practice.

Iran's scientific impact has suffered hard from decades of imposed and self‐elected isolation from Western influences and international collaboration. Lately, however, the world has witnessed a remarkable increase in scientific publications from Iranian scientists in fields like nanotechnology; material science; and, perhaps most pronounced, chemistry. In this article, the factors behind this “publication boom” are discussed and examined together with an analysis of the coherence between the country's long‐term research strategies and short‐term needs in relation to present organic chemical research conducted at various Iranian universities and institutes. Organic chemistry is a keystone in important Iranian industrial sectors like the petroleum and agricultural industries, and also in the growing field of life science and pharmacology. The development of the petroleum industry and further refinement of raw oil into value‐added fine chemicals holds a key position in the reinforcement of the Iranian economy and labor market, thus motivating a governmental investment in chemical science and research. Taking an approach to find a reasonable balance with the impact from Western and Far Eastern scientific communities, Iran's own scientific roots and Islamic ideology could well be the success factor in becoming a worthy player on the international scientific arena.  相似文献

This essay offers an ideological analysis of the rhetoric of the Islamist Egyptian Muslim Brotherhood (MB) in its official English‐language Web site, Ikhwanweb, between 2005 and 2010 — years preceding the Egyptian uprising of January 2011. The purpose was to examine the ideology manifest in the rhetoric and uncover the instrumental function the rhetoric served. Analysis brought forth a post‐Islamist ideology manifest through a rhetoric of dialectics. The instrumental function of the Egyptian MB's rhetoric in Ikhwanweb was to alter Western societies' monolithic understanding of Islamism — radical, undemocratic, inflexible. The cyber‐rhetoric was also used as a means to disapprove certain Western agents' support for authoritarian regimes. During Mubarak's rule, Ikhwanweb was used as a communicative medium to demonstrate to the West the Egyptian MB's need to be valued — respected regardless of ideological differences, understood rather than essentialized, stereotyped, and prejudged, and supported as a pragmatic, political entity within Egypt.  相似文献

Former Prime Minister Iyad Allawi stunned the Iraqi and American political establishment with his comeback success in Iraq's 2010 election. Speculation immediately began to focus on how his coalition could have won the most seats, focusing on disaffection with the status quo. But the answer could come from a tactic Allawi has repeatedly used: tying his domestic political opponents to countries that Iraq has clashed with in the past, to reignite old hatreds and fears. This article investigates, not only how Allawi and even his rivals have adopted such a strategy, but also how our current understanding of the diversionary theory of conflict needs to be modified to see how politicians in other places play this wag the dog game.  相似文献
