This article questions the diverse and, in some cases, contradictory ethical forms present in contemporary neoliberal policy frames. In particular, we analyse the demands of responsibility – as a form of ethical commitment – requested of parents by education policies in the contexts of Chile and Australia. Assuming neoliberalism as a contextualised and multivocal form of governing, we applied a policy sociology approach to study the ethical implications for parents of two recent educational reforms developed in the national contexts of this research. Our analyses show that the emerging demands on parents for responsibility in the educational field exceed univocal forms of individual responsibilisation, encompassing expressions of responsibility that respond to collective and public goals.

Telecoupled systems connect consumption and other choices in one part of the world with land-use and land-cover change in another. While such connections are increasingly well documented, research on governing telecoupled systems is in its infancy. Drawing on recent discussions in sociology, we argue that models for governing telecoupled systems must consider two types of information flows. Low-bandwidth flows allow for limited information transfer but can take place over greater distances. High-bandwidth flows, by contrast, allow for more complex knowledge transfer but tend to be geographically localized due to the costs of maintaining robust connections. Using a mixed-methods case study of national sustainability certification in the wine sector in Australia and Chile, we argue that Chile's counterintuitive success in diffusing its national sustainability certification relates to its geography, which facilitated high-bandwidth connections. We conclude that telecoupling governance measures, such as jurisdictional commodity certification, need to consider the unique requirements and costs of high-bandwidth connections in allocating institutional investments.

Blood flukes are digeneans that infect wild and farmed fish that can cause a severe and potentially lethal disease in farmed fish. These parasites are undetectable in the larval stage based on macroscopic observations in the definitive host with the infection becoming evident when eggs accumulate in the branchial vessels. There are nine known species of the genus Paradeontacylix and seven exclusively parasitize Seriola spp. from several geographical areas. Seriola lalandi aquaculture farms are emerging at various localities in northern Chile. Here, we report, for the first time, two blood fluke species parasitizing S. lalandi in the Southeastern Pacific (Chile). In the laboratory, the gills and heart of fish were removed. The retained blood flukes were separated according to the infection site, fixed in 70% or 95% ethanol for taxonomic and molecular analysis, respectively. Morphometrical differences among the fluke species were evaluated with a principal component analysis (PCA) using proportional body measurements. Phylogenetic trees were constructed based on 28S rDNA, cox1 mDNA using Bayesian inference (BI), and maximum likelihood (ML). Based on morphology, morphometry, and molecular analyses, two new species are proposed: P. humboldti n. sp. from the gills and P. olivai n. sp. from the heart of S. lalandi. Both were clearly distinguished from other species of Paradeontacylix by a combination of morphologic features (posterior tegumental spines, testes arrangement, body size). The genetic distance (based on cox1) among species was >10%. P. humboldti n. sp. and P. olivai n. sp. are sister species (with a common ancestor) independent of P. godfreyi from S. lalandi in Australia. The newly identified parasites may pose a risk to farmed S. lalandi as aporocotylids have been the cause of diseases in farmed fish from other geographical areas. In addition, some cages of S. lalandi are currently maintained in an open circulating system, which could favor the transmission of these parasites (if involved hosts are present in the environment).
