Engaging with recent scholarship on the relations among science, resources, and territory, this paper examines role of late-nineteenth-century mineral science in rendering Peruvian underground as a knowable actionable space. I focus mineralogical work Italian-born naturalist Antonio Raimondi, identifying it dual dynamic geo-political differentiation ontological dedifferentiation. On one hand, R...

I estimate the effect that growth in countries’ GDP per capita has on rate of infrastructure. In order to extract exogenous variation growth, use international oil price multiplied with shares net-exports as an instrumental variable. My variables estimates show that, for both democracies and autocracies, a significant positive infrastructure growth. This is significantly smaller anocracies—so m...

Although sentiments like are typically imagined fall outside firm's purview, companies actively blur distinctions between economic-material and social-emotional realms when they draw on intimate social forms kin networks communal...

Let G = ( V, E ) be a graph of order n and let B D the set vertices in V \ that have neighbor vertex . The differential is defined as ∂ |B(D)| − |D| maximum value for any subset A said to dominating if every adjacent dominant it contains -set which also set. This paper devoted computation wheel, cycle path-related graphs infrastructure networks. Furthermore, types networks are recognized.

today, information technology services are considered as valuable resources in all areas. for making information technology management processes purposeful and efficient in different organizations – as a competitive and strategic advantage (especially in organizations responsible for health care services) – it is necessary to recognize the level of maturity of the organization and review its pr...

advanced metering infrastructure (ami) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication.  this study focuses on communication between a smart meter and a server on the utility side. hence, a mutual authentication mechanism in ami is presented based on the elliptic curve cryptography (ecc) and one time signature (ots) consists o...
