Governance Of Land And Natural Resource For Sustainable Development In Botswana: Possible Lessons For The Agricultural And Tourism Sectors, David Sebudubudu, Patricia M. Makepe, Kgomotso Montsi, Keratilwe Bodilenyane

International Journal of African Development

Realizing sustainable development is a major challenge for most African countries. Economic growth in most African countries is largely centered on the extraction of natural resources, particularly minerals. Rather than facilitate development, the extraction of natural resources in most countries, has been a source of adverse outcomes. That is, natural resources led to ‘the resource curse’, partly because of bad governance and leadership. Through governance and leadership, Botswana emerged differently. The country transformed itself to a middle income status through the prudent utilization and management of mineral (non-renewable) resources; making Botswana one of the few resource rich countries that have …


Advantages Of A Finite Extensible Nonlinear Elastic Potential In Lattice Boltzmann Simulations, Tai-Hsien Wu, Dewei Qi Jan 2015

Advantages Of A Finite Extensible Nonlinear Elastic Potential In Lattice Boltzmann Simulations, Tai-Hsien Wu, Dewei Qi

The Hilltop Review

A new structure, generalized lattice nonlinear spring model (GLNSM), which adopts non-linear FENE-LJ potential instead of harmonic potential, has been coupled with lattice Boltzmann simulation for solving fluid-solid interaction problem. In this article, a significant work is the relationship between the GLNSM (FENE-LJ potential) and Young’s modulus has been described in detail. A validation has also been presented to prove that GLNSM is reliable.


Wi-Fi Location Determination For Semantic Locations, Keith J. Kelley Jan 2015

Wi-Fi Location Determination For Semantic Locations, Keith J. Kelley

The Hilltop Review

In Wi-Fi location determination literature, little attention is paid to locations that do not have numeric, geometric coordinates, though many users prefer the convenience of non-coordinate locations (consider the ease of giving a street address as opposed to giving latitude and longitude). It is not often easy to tell from the title or abstract of a Wi-Fi location determination article whether or not it has applicability to semantic locations such as room-level names. This article surveys the literature through 2011 on Wi-Fi localization for symbolic locations.


Advocating For Mother Earth In The Undergraduate Classroom: Uniting Twenty-First Century Technologies, Local Resources, Art, And Activism To Explore Our Place In Nature, Christina Triezenberg Ph.D., Ilse A. Schweitzer Vandonkelaar Jan 2015

Advocating For Mother Earth In The Undergraduate Classroom: Uniting Twenty-First Century Technologies, Local Resources, Art, And Activism To Explore Our Place In Nature, Christina Triezenberg Ph.D., Ilse A. Schweitzer Vandonkelaar

The Hilltop Review

Despite the growing evidence of humanity’s impact on the natural world and the urgent need to shape citizens who understand the impact that their choices and actions have on their local and global environments, colleges and universities throughout the United States have been slow to add environmental education as a core component of their undergraduate curricula. Harnessing our shared interest in environment issues and the humanities, we designed and taught an experimental course in environmental literature for the honors program at Western Michigan University that we hope will become a template of what is possible in postsecondary environmental education. Using …
