Ancient Biological Invasions and Island Ecosystems: Tracking Translocations of Wild Plants and Animals

Biological invasions are one of the great threats to Earth’s ecosystems and biodiversity in the Anthropocene. However, species introductions and invasions extend deep into the human past, with the translocation of both wild and domestic species around the world. Here, we review the human translocation of wild plants and animals to the world’s islands. We focus on establishing criteria used to differentiate natural from human-assisted dispersals and the differences between non-native and invasive species. Our study demonstrates that, along with a suite of domesticates, ancient people transported numerous wild plants and animals to islands and helped shape ecosystems in ways that have important ramifications for modern conservation, restoration, and management.     

Networks of Speculation: Making Land Markets on Myanmar Facebook

Digital platforms have changed how property is sold and valued in the Global North, yet little is known about digital tools in emerging land markets. Drawing on in situ and digital ethnography, we argue that Facebook plays a key role in making a new kind of market in Myanmar, one in which land is transformed into a speculative asset, exchanged across ever-expanding networks. While commodification is familiar within longer histories of capitalism, this case highlights the significance of digital platforms to the contemporary remaking of property relations. Unlike classic cases of market-making enabled by active state regulation, Myanmar’s digital land markets were forged in the context of state absence by brokers who harnessed the technological affordances of social media to increase the scale, scope and speed of transactions. This creative re-appropriation of the platform forged new, unregulated digital markets that ultimately accumulated corporate profits and intensified participant risk.

Strategic Alliances in Action: Toward a Theory of Evolution

The popularity and prevalence of strategic alliances for problem solving has been well documented in research on the corporate sector and public policy. However, there has been limited work to date on building a comprehensive theory about the evolutionary process of alliances. The purpose of this article is to synthesize current research on alliance development in order to develop a model of strategic alliance evolution. The theoretical model is built with ideas from prior research as well as findings from our own recent research on alliances in education. We conducted a national study of strategic alliances in charter schools focused on uncovering the process of evolution—including how alliances are initiated, operated, and evaluated—and the various internal and external factors that influence alliance development and progress. Our findings offer a model of strategic alliance evolution and provide direction for future research.

The Norman invasion of Gwent: a reassessment

Shortly after the Norman conquest of England, William fitz Osbern was created earl of Hereford. Most historians suggest he overran all Gwent east of the Usk before his return to the continent in 1071. This article will argue that his occupation of Gwent was more limited and was possibly confined to the territories claimed by Harold Godwinson, once earl of Hereford, before his death at Hastings. Instead, the accession of William Rufus in 1087 is seen as the context for a new aggressive policy towards South Wales. In the next fifteen years, Gwent and its neighbouring kingdoms of Morgannwg and Bucheiniog were overrun by William's marcher lords.
