Mediated Diasporas: Material Translations of the Philippines in a Globalized World

Recent work demonstrates the ways that new media and ICTs both in the Philippines and among Filipino diasporans have become central to contemporary processes of identity formation, altering and enabling the articulation of alternative selves and expanding spatially Filipino national identifications and definitions of ‘home’ (Pertierra 2002, 2006, 2010 Tyner and Kuhlke 2000, Ignacio 2005). While attending to media in the specific sense of particular social technologies of mass communication, we extend that work here drawing together new empirical studies both to demonstrate the various ways that a wide range of differently situated migrants make use of those media and by considering processes of mediation in a much broader sense (Mazzarella 2004), an approach that draws together both an analysis of the ‘materialities of migration’ (Basu and Coleman 2008) and ‘the technics of translation’ (Rafael 2005)

Polymedia: Towards a new theory of digital media in interpersonal communication

This article develops a new theory of polymedia in order to understand the consequences of digital media in the context of interpersonal communication. Drawing on illustrative examples from a comparative ethnography of Filipino and Caribbean transnational families, the article develops the contours of a theory of polymedia. We demonstrate how users avail themselves of new media as a communicative environment of affordances rather than as a catalogue of ever proliferating but discrete technologies. As a consequence, with polymedia the primary concern shifts from the constraints imposed by each individual medium to an emphasis upon the social, emotional and moral consequences of choosing between those different media. As the choice of medium acquires communicative intent, navigating the environment of polymedia becomes inextricably linked to the ways in which interpersonal relationships are experienced and managed. Polymedia is ultimately about a new relationship between the social and the technological, rather than merely a shift in the technology itself

Mobile phone parenting: Reconfiguring relationships between Filipina migrant mothers and their left-behind children

The Philippines is an intensely migrant society with an annual migration of one million people, leading to over a tenth of the population working abroad. Many of these emigrants are mothers who often have children left behind. Family separation is now recognized as one of the social costs of migration affecting the global south. Relationships within such transnational families depend on long-distance communication and there is an increasing optimism among Filipino government agencies and telecommunications companies about the consequences of mobile phones for transnational families. This article draws on comparative research with UK-based Filipina migrants - mainly domestic workers and nurses - and their left-behind children in the Philippines. Our methodology allowed us to directly compare the experience of mothers and their children. The article concludes that while mothers feel empowered that the phone has allowed them to partially reconstruct their role as parents, their children are significantly more ambivalent about the consequences of transnational communication

Protect global values of the Southern Ocean ecosystem

The Southern Ocean, which comprises ∼10% of the global ocean, is critically important to the homeostasis of the Earth system, exhibits distinctive marine biodiversity, and has tremendous scientific, diplomatic, and wilderness value. Yet, the region and its suite of global values are critically threatened by climate change, which is exacerbated by commercial fishing, an activity that provides value for relatively few industrial actors and compromises the greater values that the Southern Ocean ecosystem provides to the world. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the arm of the Antarctic Treaty System responsible for managing Southern Ocean marine living resources, meets in October–November 2022 and is under pressure to strengthen fisheries management, especially toward climate change resilience. We encourage improved management practices that account for the environmental externalities arising from trade-offs between fishing and the global contribution of the Southern Ocean ecosystem, including under a changing climate.The Pew Charitable Trusts; Biodiversa ASICS.

Digital Inequality and Second-Order Disasters: Social Media in the Typhoon Haiyan Recovery

This article investigates the intersection of digital and social inequality in the context of disaster recovery. In doing so, the article responds to the optimism present in recent claims about “humanitarian technology” which refers to the empowering uses and applications of interactive technologies by disaster-affected people. Drawing on a long-term ethnography with affected communities recovering from Typhoon Haiyan that hit the Philippines in 2013 triggering a massive humanitarian response, the article offers a grounded assessment of the role of social media in disaster recovery. In particular, the article focuses on whether any positive consequences associated with digital media use are equally spread among better off and socially marginalized participants. The analysis reveals sharp digital inequalities which map onto existing social inequalities. While some of our already better-off participants have access to a rich media landscape which they are able to navigate often reaping significant benefits, low-income participants are trapped in a delayed recovery with diminished social media opportunities. The fact that some participants are using social media to recover at a rapid pace while others are languishing behind represents a deepening of social inequalities. In this sense, digital inequality can amplify social inequalities leading to a potential “second-order disaster.” This refers to humanly perpetuated disasters that can even surpass the effects of the natural disaster

An expert-driven framework for applying eDNA tools to improve biosecurity in the Antarctic

Signatories to the Antarctic Treaty System’s Environmental Protocol are committed to preventing incursions of non-native species into Antarctica, but systematic surveillance is rare. Environmental DNA (eDNA) methods provide new opportunities for enhancing detection of non-native species and biosecurity monitoring. To be effective for Antarctic biosecurity, eDNA tests must have appropriate sensitivity and specificity to distinguish non-native from native Antarctic species, and be fit-for-purpose. This requires knowledge of the priority risk species or taxonomic groups for which eDNA surveillance will be informative, validated eDNA assays for those species or groups, and reference DNA sequences for both target non-native and related native Antarctic species. Here, we used an expert elicitation process and decision-by-consensus approach to identify and assess priority biosecurity risks for the Australian Antarctic Program (AAP) in East Antarctica, including identifying high priority non-native species and their potential transport pathways. We determined that the priority targets for biosecurity monitoring were not individual species, but rather broader taxonomic groups such as mussels (Mytilus species), tunicates (Ascidiacea), springtails (Collembola), and grasses (Poaceae). These groups each include multiple species with high risks of introduction to and/or establishment in Antarctica. The most appropriate eDNA methods for the AAP must be capable of detecting a range of species within these high-risk groups (e.g., eDNA metabarcoding). We conclude that the most beneficial Antarctic eDNA biosecurity applications include surveillance of marine species in nearshore environments, terrestrial invertebrates, and biofouling species on vessels visiting Antarctica. An urgent need exists to identify suitable genetic markers for detecting priority species groups, establish baseline terrestrial and marine biodiversity for Antarctic stations, and develop eDNA sampling methods for detecting biofouling organisms

Biogeographical survey of soil microbiomes across sub-Saharan Africa:structure, drivers, and predicted climate-driven changes

BACKGROUND: Top-soil microbiomes make a vital contribution to the Earth’s ecology and harbor an extraordinarily high biodiversity. They are also key players in many ecosystem services, particularly in arid regions of the globe such as the African continent. While several recent studies have documented patterns in global soil microbial ecology, these are largely biased towards widely studied regions and rely on models to interpolate the microbial diversity of other regions where there is low data coverage. This is the case for sub-Saharan Africa, where the number of regional microbial studies is very low in comparison to other continents. RESULTS: The aim of this study was to conduct an extensive biogeographical survey of sub-Saharan Africa’s top-soil microbiomes, with a specific focus on investigating the environmental drivers of microbial ecology across the region. In this study, we sampled 810 sample sites across 9 sub-Saharan African countries and used taxonomic barcoding to profile the microbial ecology of these regions. Our results showed that the sub-Saharan nations included in the study harbor qualitatively distinguishable soil microbiomes. In addition, using soil chemistry and climatic data extracted from the same sites, we demonstrated that the top-soil microbiome is shaped by a broad range of environmental factors, most notably pH, precipitation, and temperature. Through the use of structural equation modeling, we also developed a model to predict how soil microbial biodiversity in sub-Saharan Africa might be affected by future climate change scenarios. This model predicted that the soil microbial biodiversity of countries such as Kenya will be negatively affected by increased temperatures and decreased precipitation, while the fungal biodiversity of Benin will benefit from the increase in annual precipitation. CONCLUSION: This study represents the most extensive biogeographical survey of sub-Saharan top-soil microbiomes to date. Importantly, this study has allowed us to identify countries in sub-Saharan Africa that might be particularly vulnerable to losses in soil microbial ecology and productivity due to climate change. Considering the reliance of many economies in the region on rain-fed agriculture, this study provides crucial information to support conservation efforts in the countries that will be most heavily impacted by climate change.

Diasporic Encounters, Sacred Journeys: Ritual, Normativity and the Religious Imagination Among International Asian Migrant Women

This issue highlights recent ethnographic work that discloses migrant women’s creative engagements with the people and landscapes in the places they migrate to. We challenge a dominant view that construes women international migrants from Asia as docile bodies shaped and constrained by their transnational (re)productive labours. And we reject simplistic contemporary formulations of transnational migration that posit a singular, homogeneous ‘transnational social field’. Three key processes, relatively ignored and under theorised are interrogated: diaspora formation, ritual performance and changing normativities. A focus on diaspora encourages us to move beyond a political and economic analysis to consider cultural practices, continuities and discontinuities in migrants’ relationships with the people and places they travel to, as well as those left behind. A focus on ritual emphasises the significance of religious performance in the making of place and convivial sociality. A focus on normativity foregrounds the ways that people’s affective relationships are performatively reworked and transgressed within and across discrepant diasporic spaces
