Stealing the sacred: Why ‘global heritage’ discourse is perceived as a frontal attack on local heritage-making in Madagascar

This article analyses Malagasy notions of land as heritage through the concept of fomba gasy, known as ‘Malagasy customs’, within the context of foreign land acquisitions for mineral extraction. Fomba gasy is a concept intimately tied to land – as it provides a social, economic, existential, cultural, and ontological web, which ties past, present and future generations. Global or ‘western’ conceptualizations of heritage generally adopt a more static definition of land as their point of departure, wherein biodiversity or clearly demarcated ‘heritage sites’ become objects of frontier conservation. This vision directly conflicts with Malagasy conceptions and ontologies of fomba gasy – a concept inherently anchored in dynamic, material and intangible uses of land. The model of heritage as universal patrimony does not sit easily with beliefs held by local (land - based) groups within Madagascar. On the contrary, it challenges a core tenet of Malagasy power and belief: their sovereign right to define fomba gasy and heritage through land, and to harness the powers of the sacred. The contested nature of heritage claims in Madagascar is discussed using a case study concerning a mining/biodiversity protection project where international and local stakeholders are vying for the same land.RÉSUMÉCet article analyse la notion des terres malgaches en tant que patrimoine à travers le concept de fomba gasy (‘coutumes malgaches’), dans le cadre de l’acquisition de terres par des compagnies étrangères pour les extractions de minéraux. Fomba gasy est un concept étroitement lié à la terre car il fournit une toile environnementale, sociale, économique, existentielle, culturelle et ontologique, qui relie les générations passées, présentes et futures. Les conceptualisations globales ou occidentales du patrimoine tendent généralement à adopter une définition plus statique de la terre comme point de départ. Cette vision se heurte nécessairement à celle de fomba gasy : un concept fondamentalement ancré dans la dynamique matérielle et immatérielle d’exploitation des terres. Au contraire, il remet en cause un principe fondamental et sacré du pouvoir malgache : le droit souverain de définir le fomba gasy et le patrimoine à travers la terre. Cet article discute un différend foncier à Madagascar où un projet minier et de protection de la biodiversité locale met en opposition divers intervenants revendiquant tous des intérêts dans les mêmes terres

The melting curve of iron at extreme pressures: implications for planetary cores

Exoplanets with masses similar to that of Earth have recently been discovered in extrasolar systems. A first order question for understanding their dynamics is to know whether they possess Earth like liquid metallic cores. However, the iron melting curve is unknown at conditions corresponding to planets of several times the Earth's mass (over 1500 GPa for planets with 10 times the Earth's mass (ME)). In the density-temperature region of the cores of those super-Earths, we calculate the iron melting curve using first principle molecular dynamics simulations based on density functional theory. By comparing this melting curve with the calculated thermal structure of Super Earths, we show that planets heavier than 2ME, have solid cores, thus precluding the existence of an internal metallic-core driven magnetic field. The iron melting curve obtained in this study exhibits a steeper slope than any calculated planetary adiabatic temperature profile rendering the presence of molten metallic cores less likely as sizes of terrestrial planets increase

Cellular responses in roots of bentgrass and bermudagrass to selected herbicides

Cellular responses in roots of Penncross creeping bentgrass (Agrostis palustris Huds.) and Tifgreen bermudagrass (Cynodon dactylon (L.) Pers. x Cynodon transvaalensis Burtt-Davy) to selected herbicides were determined by a histological study. The most severe tissue abnormalities in Penncross bentgrass occurred following treatments of benefin (N-butyl-N-ethyl- , , -trifluoro-2 , 6-dinitro-p-toluidine) and terbutol (2,6-di-tert-butyl-p-tolyl methylcarbamate). Root cell damage in bentgrass was less severe with bandane (polychlorodicyclopentadiene isomers), bensulide [0,0-diisopropyl phosphorodithioate S-ester with N-(2-mercaptoethyl)benzenesulfonamide], DCPA (dimethyl tetrachloroterephthalate) and siduron [1-(2-methylcyclohexyl) 3-phenylurea]. The most severe tissue malformations in Tifgreen bermudagrass resulted from DCPA, siduron and terbutol. Cellular damage in roots of bermudagrass was less severe from bandane and bensulide, and slight with benefin

AGRICULTURAL CERTIFICATIONS AND BEEKEEPING: LESSONS FROM AN APICULTURAL COOPERATIVE IN NORTHEASTERN EL SALVADOR, CENTRAL AMERICA

Beekeeping, and especially the production and sale of honey, is an on-farm diversification strategy that has significance to rural livelihoods in some of the most economically and environmentally marginalized regions of the world. Beekeeping also supports sustainable agriculture since it requires that vegetation and forest cover remain intact. However, the limited resources of beekeepers, including marketing constraints, make it difficult for them to realize the full value of their beekeeping enterprises. This professional paper focuses on the Eco-Morazán Cooperative in El Salvador as a case study to examine the costs, benefits and market potential of three types of certification schemes: 1) Fair Trade, 2) Organic, and 3) Rainforest Alliance Certification. The paper draws on information from existing literature, and extended field visits and informal interviews with representatives from the cooperative. It concludes with recommendations on how the cooperative can take advantage of the benefits of these certification schemes. These include suggestions for both the cooperative and Rainforest Alliance initiative, the only one of the three not currently certifying apicultural production

A Framework for File Format Fuzzing with Genetic Algorithms

Secure software, meaning software free from vulnerabilities, is desirable in today\u27s marketplace. Consumers are beginning to value a product\u27s security posture as well as its functionality. Software development companies are recognizing this trend, and they are factoring security into their entire software development lifecycle. Secure development practices like threat modeling, static analysis, safe programming libraries, run-time protections, and software verification are being mandated during product development. Mandating these practices improves a product\u27s security posture before customer delivery, and these practices increase the difficulty of discovering and exploiting vulnerabilities. Since the 1980\u27s, security researchers have uncovered software defects by fuzz testing an application. In fuzz testing\u27s infancy, randomly generated data could discover multiple defects quickly. However, as software matures and software development companies integrate secure development practices into their development life cycles, fuzzers must apply more sophisticated techniques in order to retain their ability to uncover defects. Fuzz testing must evolve, and fuzz testing practitioners must devise new algorithms to exercise an application in unexpected ways. This dissertation\u27s objective is to create a proof-of-concept genetic algorithm fuzz testing framework to exercise an application\u27s file format parsing routines. The framework includes multiple genetic algorithm variations, provides a configuration scheme, and correlates data gathered from static and dynamic analysis to guide negative test case evolution. Experiments conducted for this dissertation illustrate the effectiveness of a genetic algorithm fuzzer in comparison to standard fuzz testing tools. The experiments showcase a genetic algorithm fuzzer\u27s ability to discover multiple unique defects within a limited number of negative test cases. These experiments also highlight an application\u27s increased execution time when fuzzing with a genetic algorithm. To combat increased execution time, a distributed architecture is implemented and additional experiments demonstrate a decrease in execution time comparable to standard fuzz testing tools. A final set of experiments provide guidance on fitness function selection with a CHC genetic algorithm fuzzer with different population size configurations

On a Testing Methodology for the Mechanical Property Assessment of a New Low-Cost Titanium Alloy Derived from Synthetic Rutile

Mechanical property data of a low-cost titanium alloy derived directly from synthetic rutile is reported. A small-scale testing approach comprising consolidation via field-assisted sintering technology, followed by axisymmetric compression testing, has been designed to yield mechanical property data from small quantities of titanium alloy powder. To validate this approach and provide a benchmark, Ti-6Al-4V powder has been processed using the same methodology and compared with material property data generated from thermo-physical simulation software. Compressive yield strength and strain to failure of the synthetic rutile-derived titanium alloy were revealed to be similar to that of Ti-6Al-4V

Disaggregating Seasonal Demand of a Coastal Resort

Recent national studies document the fact that the lackluster performance in the lodging industry\u27s occupancy rates are directly attributable to the steady growth in the supply of available rooms at a rate that consistently outpaced the demand. Resort area managers who are facing this decade-long reduction in occupancy rates are especially cognizant of the need to revise current market strategies to shield their properties from additional economic fallout that are often triggered by external events. One purpose of the Hilton Head Island Study to determine if a chase demand strategy, where resort capacities are varied with changes in the level of demand, was the proper strategy for the Hilton Head Island destination resort area. Results indicated that visitors utilized timeshare, campgrounds and rental properties more often during the winter season because of their longer average stay. This study also documented the fact that winter season visitors differed significantly from peak season visitors with respect to the level of importance they placed upon many of the hospitality and travel-related amenities in the area. The Hilton Head Island resort should take a chase demand strategy as the basic strategic marketing approach for the winter-season development
