TL;DR: In this article, the authors identify eight recent surges in the region and map their surface velocities using cross-correlation feature tracking on optical satellite imagery, and propose that these surges represent a spectrum of flow instabilities and the processes controlling their evolution may vary on a glacier by glacier basis.
Abstract: Many Karakoram glaciers periodically undergo surges during which large volumes of ice and debris are rapidly transported downglacier, usually at a rate of 1–2 orders of magnitude greater than during quiescence. Here we identify eight recent surges in the region and map their surface velocities using cross-correlation feature tracking on optical satellite imagery. In total, we present 44 surface velocity data sets, which show that Karakoram surges are generally short-lived, lasting between 3 and 5 years in most cases, and have rapid buildup and relaxation phases, often lasting less than a year. Peak velocities of up to 2 km a−1 are reached during summer months, and the surges tend to diminish during winter months. Otherwise, they do not follow a clearly identifiable pattern. In two of the surges, the peak velocity travels down-ice through time as a wave, which we interpret as a surge front. Three other surges are characterized by high velocities that occur simultaneously across the entire glacier surface, and acceleration and deceleration are close to monotonic. There is also no consistent seasonal control on surge initiation or termination. We suggest that the differing styles of surge can be partly accounted for by individual glacier configurations and that while some characteristics of Karakoram surges are akin to thermally controlled surges elsewhere (e.g., Svalbard), the dominant surge mechanism remains unclear. We thus propose that these surges represent a spectrum of flow instabilities and the processes controlling their evolution may vary on a glacier by glacier basis.

TL;DR: A process-based carbonate budget was used to compare carbonate framework production at two reef sites subject to varying degrees of fluvial influence in Rio Bueno, Jamaica as mentioned in this paper.
Abstract: A process-based carbonate budget was used to compare carbonate framework production at two reef sites subject to varying degrees of fluvial influence in Rio Bueno, Jamaica. The turbid, central embayment was subjected to high rates of fluvial sediment input, framework accretion was restricted to ≤30 m, and net carbonate production was 1,887 g CaCO3 m−2 year−1. Gross carbonate production (GCP) was dominated by scleractinians (97%), particularly by sediment-resistant species, e.g. Diploria strigosa on the reef flat (<2 m). Calcareous encrusters contributed very little carbonate. Total bioerosion removed 265 g CaCO3 m−2 year−1 and was dominated by microborers. At the clear-water site, net carbonate production was 1,236 g CaCO3 m−2 year−1; the most productive zone was on the fore-reef (10 m). Corals accounted for 82% of GCP, and encrusting organisms 16%. Bioerosion removed 126 g CaCO3 m−2 year−1 and was dominated by macroborers. Total fish and urchin grazing was limited throughout (≤20 g CaCO3 m−2 year−1). The study demonstrates that: (1) carbonate production and net reef accretion can occur where environmental conditions approach or exceed perceived threshold levels for coral survival; and (2) although live coral cover (and carbonate production rates) were reduced on reef-front sites along the North Jamaican coast, low population densities of grazing fish and echinoids to some extent offset this, thus maintaining positive carbonate budgets.

TL;DR: The authors argue that we are living in an historical epoch which might be described as neoliberal-ableism, in which we are all subjected to slow death, increased precarity and growing debility.
Abstract: The forthcoming book Dis/ability Studies: Theorising Disablism and Ableism argues that we are living in an historical epoch which might be described as neoliberal-ableism, in which we are all subjected to slow death, increased precarity and growing debility. In this paper we apply this analysis to a consideration of austerity with further reference to disability studies and politics.

TL;DR: In this paper, the authors investigated a sample of plastics-converting companies in Emilia Romagna region (Italy), which stand out for radical innovations in business models, with the aim to catalyse changes in current manufacturing practices, and provided empirical support for a positive relationship between business strategies and the use of non-virgin plastic materials.

TL;DR: This article describes first steps towards the formal specification and verification of multi-agent systems, through the use of temporal belief logics, and develops a logic that may be used to reason about Concurrent METATEM systems.
Abstract: This article describes first steps towards the formal specification and verification of multi-agent systems, through the use of temporal belief logics. The article first describes Concurrent METATEM, a multi-agent programming language, and then develops a logic that may be used to reason about Concurrent METATEM systems. The utility of this logic for specifying and verifying Concurrent METATEM systems is demonstrated through a number of examples. The article concludes with a brief discussion on the wider implications of the work, and in particular on the use of similar logics for reasoning about multi-agent systems in general.
