title: Information and communication technology adoption and diffusion in micro-enterprises: the case of techno-savvy home-based businesses

authors: Clark, Delwyn N.

subjects: micro enterprises

abstract: The effective use of ICTs for business activities is of significant interest in a digital economy. This paper examines the adoption and diffusion of ICTs by micro home-based businesses (HBB) from an empirical study of 522 firms. Key findings include very high levels of internet, e-mail and cell phone usage for HBBs' business activities; and increasing website adoption levels with increasing geographic sales reach (from local, regional, national, to international). In spite of micro size and limited resources, many of these HBB were techno-savvy and capable of utilising the full range of ICTs to facilitate electronic business communications and online transactions. These findings are significant given the lack of prior research on the HBB sector and the scale of micro-enterprises in economies around the globe.

title: The role of vicariance and dispersal on New Zealand's estuarine biodiversity: the case of Paracorophium (Crustacea: Amphipoda)

authors: Knox, Matthew Andrew

subjects: allopatric isolation

abstract: To investigate the role of vicariance and dispersal on New Zealand's estuarine biodiversity, we examined variability in mitochondrial cytochrome c oxidase subunit I (COI) gene sequences for the amphipod genus Paracorophium. Individuals from the two nominate endemic species (Paracorophium excavatum and Paracorophium lucasi) were collected from sites throughout the North and South Islands. Sequence divergences of 12.8% were detected among the species. However, divergences of up to 11.7% were also observed between well supported clades, suggesting the possibility of cryptic species. Nested clade analyses identified four distinct lineages from within both P. excavatum and P. lucasi, with boundaries between clades corresponding to topographical features (e.g. Cook Straight, North and East Cape). Sequence divergences of 3.7–4.9% were also observed within geographic regions (e.g. east and west coasts of the upper North Island). Genetic structure in Paracorophium appears to represent prolonged isolation and allopatric evolutionary processes dating back to the Upper Miocene and continuing through the Pliocene and early Pleistocene. On the basis of molecular clock estimates from sequence divergences and reconstructions of New Zealand's geological past, we suggest that sea level and landmass changes during the early Pleistocene (2 Mya) resulted in the isolation of previously contiguous populations leading to the present-day patterns. COI genetic structure was largely congruent with previously observed allozyme patterns and highlights the utility of COI as an appropriate marker for phylogeographic studies of the New Zealand estuarine fauna.

title: Indigenous peoples, data, and the coloniality of surveillance

authors: Cormack, Donna

abstract: In Aotearoa New Zealand (Aotearoa NZ), Māori (the Indigenous peoples of New Zealand) have long been objects of surveillance by state institutions and agents. State representations have centred on constructions of difference and deviance, on understandings of Indigenous peoples as dangerous, and on the management of Indigenous resistance to colonialism. This chapter considers how contemporary state surveillance practices in Aotearoa NZ, enabled by the expanded use of big data and linked government datasets, function to regulate and manage Māori. Through this lens, we explore continuities of current data practices for Indigenous peoples with the racialised logics and social orders set in place as part of global systems of imperialism and colonialism. Recognising that resistance has always been a part of Indigenous responses to colonialism, we also explore how Māori Data Sovereignty (MDSov), as part of broader Indigenous Data Sovereignty (IDS) movements globally, provides opportunities to counter and disrupt prevailing data relations and to imagine alternative futures.
