Care, not incarceration: exploring the carcerality of fisheries enforcement and potential decolonial futures in Hawai'i.

Current U.S. environmental management paradigms default to enforcement mechanisms that feed into the prison industrial complex, such as fines and jailing. To avoid contributing to and reinforcing mass incarceration and militarism, environmental management systems need to be transformed towards non-carceral forms. Additionally, working towards Indigenous sovereignty and decolonization, requires the strengthening of Indigenous relations with and governance over the land under the respective paradigms of Indigenous communities. This paper uses Hawai'i state fisheries law and programmatic efforts to address a central question: What is the extent and nature of carceral norms within conventional environmental management systems and how do they affect management outcomes? The study examines the current fisheries enforcement scheme in Hawai'i, tracing the embedded logic of carcerality, the degree to which ultimate sources of harm are addressed, and the concentration of governing powers. The results highlight how current fisheries enforcement is insufficient in caring for the seascape and, through its carceral approach, contributes to social injustices, particularly for Kanaka Maoli (Native Hawaiians). Additionally, this paper demonstrates how current efforts in Hawai'i - Community-Based Subsistence Fisheries Areas (CBSFAs), the 'Aha Moku system, and the Makai Watch Program - attempt to empower communities, but ultimately keep enforcement powers centralized within the State, thus perpetuating dependency on the criminal justice system. This study ends with a discussion on how future decarceral environmental governance systems could be designed to center Hawaiian relations & paradigms, particularly by prioritizing the values of re-education, rematriation, and restoration.

Nearly 400 million people are at higher risk of schistosomiasis because dams block the migration of snail-eating river prawns.

Dams have long been associated with elevated burdens of human schistosomiasis, but how dams increase disease is not always clear, in part because dams have many ecological and socio-economic effects. A recent hypothesis argues that dams block reproduction of the migratory river prawns that eat the snail hosts of schistosomiasis. In the Senegal River Basin, there is evidence that prawn populations declined and schistosomiasis increased after completion of the Diama Dam. Restoring prawns to a water-access site upstream of the dam reduced snail density and reinfection rates in people. However, whether a similar cascade of effects (from dams to prawns to snails to human schistosomiasis) occurs elsewhere is unknown. Here, we examine large dams worldwide and identify where their catchments intersect with endemic schistosomiasis and the historical habitat ranges of large, migratory Macrobrachium spp. prawns. River prawn habitats are widespread, and we estimate that 277-385 million people live within schistosomiasis-endemic regions where river prawns are or were present (out of the 800 million people who are at risk of schistosomiasis). Using a published repository of schistosomiasis studies in sub-Saharan Africa, we compared infection before and after the construction of 14 large dams for people living in: (i) upstream catchments within historical habitats of native prawns, (ii) comparable undammed watersheds, and (iii) dammed catchments beyond the historical reach of migratory prawns. Damming was followed by greater increases in schistosomiasis within prawn habitats than outside prawn habitats. We estimate that one third to one half of the global population-at-risk of schistosomiasis could benefit from restoration of native prawns. Because dams block prawn migrations, our results suggest that prawn extirpation contributes to the sharp increase of schistosomiasis after damming, and points to prawn restoration as an ecological solution for reducing human disease.This article is part of the themed issue 'Conservation, biodiversity and infectious disease: scientific evidence and policy implications'.

Can local voluntary environmental programs "work"? An examination of Fort Collins' (Colorado) climate wise program.

Previous research on voluntary environmental programs (VEPs) frequently assesses the effectiveness of federal, state, and third party programs and why organizations seek to join such programs. Yet, research has yet to evaluate the effectiveness or firm motivation relative to local VEPs. Recognizing this gap, our paper examines the structure and organization of Fort Collins' Climate Wise program, a local VEP. Using a variety of sources, we find that the program has successfully met both short- and long-term goals by persistently self-evaluating and seeking outside financial support. Findings from this analysis can aid in understanding and developing local VEPs elsewhere. Specifically, this initial research suggests that local VEPs need to consider local context and available resources when implementing such programs. Furthermore, it is possible for local VEPs to attract a diverse variety of participating firms by avoiding one-size-fits-all participation levels and by establishing a sense of ownership among partners.

Non-linear plasmon response to protein binding at a nanostructured gold particle plasmon resonance surface.

Rapid adsorption kinetics have been observed for protein binding to a 800 nm aggregated nanoparticle, showing extreme sensitivity resulting from a non-linear particle plasmon response.

pH dependence of the crystal violet adsorption isotherm at the silica-water interface.

The pH-dependent adsorption isotherms for the charged chromophore crystal violet, CV(+), have been measured with three different bases by a free-running cavity implementation of evanescent wave cavity ring-down spectroscopy. The ratio of the maximal absorbance measurements at pH 5.10 and 9.05 is consistent with a Q2:Q3 silanol site ratio of 72.8:27.2. The adsorption isotherms have been interpreted in terms a cooperative binding adsorption allowing more than one ionic species to bind to each silanol group. The surface concentration is consistent with a silanol charge density of 1.92 +/- 0.55 nm(-2) and a total neutralized interface layer structure extending 9 nm from the surface. Binding constants and stoichiometric coefficients are derived for CV(+) to both the Q2 and Q3 sites. A variation of the adsorption isotherm with base is observed so that the isotherm at pH 9.05 adjusted with ammonium hydroxide sets up a competitive acid-base equilibrium with the SiOH groups with only 49% of the surface silanol sites dissociated. The implications for functionalized surfaces in chromatography are discussed.
