    The Fallacy of Systemic Racism in the American Criminal Justice System

    Critics of the criminal justice system have repeatedly charged it with systemic racism. It is a tenet of the “war” on the “War on Drugs,” it is a justification used by the so-called “progressive prosecutors” to reject the “Broken Windows” theory of law enforcement, and it is an article of faith of the “Defund the Police!” movement. Even President Joe Biden and his chief lieutenants leveled the same allegation early in this administration. Although the President has eschewed the belief that Americans are a racist people, others have not, proclaiming that virtually anyone who is white is a racist. Yet, few people have defined what they mean by that term. This Article examines what it could mean and tests the truth of the systemic racism claim under each possible definition. None stands up to scrutiny. One argument is that the American citizens who run our many institutions are motivated by racial animus. But the evidence is that racial animus is no longer tolerated in society, and what is more, the criminal justice system strives to identify it when it does occur and to remedy it. Another argument says that the overtly racist beliefs and practices of the past have created lingering racist effects, but this argument cherry-picks historical facts (when it does not ignore them altogether) and fails to grapple with the country’s historic and ongoing efforts to eliminate racial discrimination. It also assumes a causal relationship between past discrimination and present disparities that is unsupported and often contradicted by the evidence. Yet another argument relies psychological research to claim that white Americans are animated by a subconscious racial animus. That research, however, has been debunked. Still another argument says that the criminal justice system is systemically racist because it has disparate effects across racial groups, but this argument looks only at the offenders’ side of the criminal justice system and fails to consider the effect of the criminal justice system on victims. Proponents of the systemic racism theory often proffer “solutions” to it. This Article examines those too and finds that many would, in fact, harm the very people they aim to help. In the context of the “War on Drugs,” where so much of the rhetoric is focused, the authors examine these arguments and solutions. The bottom line is this: the claim of systemic racism in the criminal justice system is unjustified

    Rapports Scientifiques du CIEM. Volume 6, nº 12The Workshop on Assessing the Impact of Fishing on Oceanic Carbon (WKFISHCARBON) was set up to provide ICES and stakeholders with a summary of knowledge on the role of fishing in the process of carbon budgets, sequestration and footprint in the ocean. The workshop addressed the potential impact of fishing on the biological carbon pump (BCP), the possible impacts of bottom trawling on carbon stores in the seabed, as well as considering emissions from fishing vessels. The overall aim was to generate proposals on how to develop an ICES approach to fishing and its role in the ocean carbon budget, and to develop a roadmap for a way forward. The main findings were that knowledge of the BCP in the open ocean was reasonably well developed, but that key gaps existed. In particular, information on the biomass of mesopelagic fish and other biota, and of some of the key processes e.g. fluxes and fish bioenergetics. Knowledge is much weaker for the BCP in shelf seas, where the bulk of fishing occurs. In particular, while biomass of fish was often well quantified, unlike the open ocean, the understanding of the important processes was lacking, particularly for the fate of faecal pellets and deadfall at the seabed. There is extensive scientific knowledge of the impact of fishing on the seabed, but what is un-clear is what it means for seabed carbon storage. There have been numbers of studies, which give a very divided view on this. There has also been open controversy about this in the literature. Physical disturbance to the seabed from fishing can affect sediment transport and has the potential to facilitate remineralization, but precise impacts will depend on habitat, fishing métier, and other environmental factors. From this, it is clear that more research is needed to resolve the controversy, and to quantify the impacts from different fishing gears and on different substrates or habitats in terms of carbon storage. There has been much more research on minimizing fuel use by fishing vessels, and hence emissions, but this has mainly focused on fuel efficiency, fuel use per unit of landed catch, and less on the total emissions. Baselines for fuel use are available at the global level, but are lacking at the national and vessel level. There is a need for standardization of methodologies and protocols, and for improving the uptake of fuel conservation measures by industry, as well as for improving the uptake of existing and potential fuel conservation and efficiency measures by industry. Finally, a roadmap was proposed to develop research and synthesis, on the understandings of the processes involved, the metrics and how to translate this into possible advice for policy-makers. To that end, a further workshop was proposed in 2024.info:eu-repo/semantics/publishedVersio

    Evolutionary ecology of obligate fungal and microsporidian invertebrate pathogens

    Get PDF
    The interactions between hosts and their parasites and pathogens are omnipresent in the natural world. These symbioses are not only key players in ecosystem functioning, but also drive genetic diversity through co-evolutionary adaptations. Within the speciose invertebrates, a plethora of interactions with obligate fungal and microsporidian pathogens exist, however the known interactions is likely only a fraction of the true diversity. Obligate invertebrate fungal and microsporidian pathogen require a host to continue their life cycle, some of which have specialised in certain host species and require host death to transmit to new hosts. Due to their requirement to kill a host to spread to a new one, obligate fungal and microsporidian pathogens regulate invertebrate host populations. Pathogen specialisation to a single or very few hosts has led to some fungi evolving the ability to manipulate their host’s behaviour to maximise transmission. The entomopathogenic fungus, Entomophthora muscae, infects houseflies (Musca domestica) over a week-long proliferation cycle, resulting in flies climbing to elevated positions, gluing their mouthparts to the substrate surface, and raising their wings to allow for a clear exit from fungal conidia through the host abdomen. These sequential behaviours are all timed to occur within a few hours of sunset. The E. muscae mechanisms used in controlling the mind of the fly remain relatively unknown, and whether other fitness costs ensue from an infection are understudied.European Commissio

    Climate Change and Critical Agrarian Studies

    Full text link
    Climate change is perhaps the greatest threat to humanity today and plays out as a cruel engine of myriad forms of injustice, violence and destruction. The effects of climate change from human-made emissions of greenhouse gases are devastating and accelerating; yet are uncertain and uneven both in terms of geography and socio-economic impacts. Emerging from the dynamics of capitalism since the industrial revolution — as well as industrialisation under state-led socialism — the consequences of climate change are especially profound for the countryside and its inhabitants. The book interrogates the narratives and strategies that frame climate change and examines the institutionalised responses in agrarian settings, highlighting what exclusions and inclusions result. It explores how different people — in relation to class and other co-constituted axes of social difference such as gender, race, ethnicity, age and occupation — are affected by climate change, as well as the climate adaptation and mitigation responses being implemented in rural areas. The book in turn explores how climate change – and the responses to it - affect processes of social differentiation, trajectories of accumulation and in turn agrarian politics. Finally, the book examines what strategies are required to confront climate change, and the underlying political-economic dynamics that cause it, reflecting on what this means for agrarian struggles across the world. The 26 chapters in this volume explore how the relationship between capitalism and climate change plays out in the rural world and, in particular, the way agrarian struggles connect with the huge challenge of climate change. Through a huge variety of case studies alongside more conceptual chapters, the book makes the often-missing connection between climate change and critical agrarian studies. The book argues that making the connection between climate and agrarian justice is crucial

    MANAGING DEATH IN TERMITES

    Get PDF
    Death of individuals from the same species represents potential risks from disease, predation or competition for animals. Diverse responses associated with death have evolved ranging from simply avoiding or being attracted to the corpses in solitary animals to complicated undertaking behavioral repertoire in eusocial insects. A systematic review in chapter 1 suggested cannibalism is an ancestral and widespread death-related behavior in all non-human animals. Termites are suggested to switch their undertaking behavioral responses from cannibalism to burial based on interactions between chemicals associated with death to balance risks and benefits associated with decomposition. In eusocial animals like termites with caste differences, conspecific death from different castes or different causes might deliver different types of risks to living members. However, whether termites are capable of distinguishing differences in conspecific death and responding accordingly remains unknown. In chapters 2 and 3, the eastern subterranean termite, Reticulitermes flavipes, was found to manage corpses from different castes or causes differentially based on both qualitative and quantitative differences in their chemical profiles. R. flavipes workers cannot distinguish dead individuals caused by termiticides apart from those killed by naturally occurring abiotic factors. Death by biotic factors accelerated the release of late death cues and the deployment of burial behavior in nestmate workers. Corpses of all castes were carried inside the nest and cannibalized when the postmortem time wasbehaviors, such as walling-off and movement of the corpse before burial were observed for 50% of soldier corpses. Postmortem chemical profiles showed that the early death cues, 3-octanone and 3-octanol, in worker corpses were significantly higher than in soldier corpses, while they were undetectable in nymphal corpses. In addition, we confirmed the existence of 3-octanol and 3-octanone in the head, thorax, abdomen, and hemolymph. Higher concentrations of early death cues were detected in the head and thorax than in the abdomen, suggesting the possible location of synthesis. Ultra-low temperature did not affect the amount or concentration across body parts, suggesting the synthesis of early death cues occurs prior to death. Our findings suggest termites equipped with delicate risk assessments on different types of conspecific death based on chemical signatures: cannibalism was the prior strategy dealing with freshly killed corpses to recycle nutrients and remove potential risks from pathogens or pesticides, whereas burial would happen when risks from disease or competition/intrusion overcome benefits associated with nutrition recycle. This study provides insights into the understanding of mechanisms of chemical-based “death recognition” in non-human animals, providing potential opportunities for further evolutionary studies of death-related behaviors

    Ecology of methanotrophs in a landfill methane biofilter

    Get PDF
    Decomposing landfill waste is a significant anthropogenic source of the potent climate-active gas methane (CH₄). To mitigate fugitive methane emissions Norfolk County Council are trialling a landfill biofilter, designed to harness the methane oxidizing potential of methanotrophic bacteria. These methanotrophs can convert CH₄ to CO₂ or biomass and act as CH₄ sinks. The most active CH₄ oxidising regions of the Strumpshaw biofilter were identified from in-situ temperature, CH₄, O₂ and CO₂ profiles. While soil CH₄ oxidation potential was estimated and used to confirm methanotroph activity and determine optimal soil moisture conditions for CH₄ oxidation. It was observed that most CH₄ oxidation occurs in the top 60cm of the biofilter (up to 50% of CH4 input) at temperatures around 50ºC, optimal soil moisture was 10-27.5%. A decrease in in-situ temperature following CH₄ supply interruption suggested the high biofilter temperatures were driven by CH₄ oxidation. The biofilter soil bacterial community was profiled by 16S rRNA gene analysis, with methanotrophs accounting for ~5-10% of bacteria. Active methanotrophs at a range of different incubation temperatures were identified by ¹³CH₄ DNA stable-isotope probing coupled with 16S rRNA gene amplicon and metagenome analysis. These methods identified Methylocella, Methylobacter, Methylocystis and Crenothrix as potential CH₄ oxidisers at the lower temperatures (30ºC/37ºC) observed following system start-up or gas-feed interruption. At higher temperatures typical of established biofilter operation (45ºC/50ºC), Methylocaldum and an unassigned Methylococcaceae species were the dominant active methanotrophs. Finally, novel methanotrophs Methylococcus capsulatus (Norfolk) and Methylocaldum szegediense (Norfolk) were isolated from biofilter soil enrichments. Methylocaldum szegediense (Norfolk) may be very closely related to or the same species as one of the most abundant active methanotrophs in a metagenome from a 50ºC biofilter soil incubation, based on genome-to-MAG similarity. This isolate was capable of growth over a broad temperature range (37-62ºC) including the higher (in-situ) biofilter temperatures (>50ºC)

    Gelatinous zooplankton diversity, distribution and seasonality in the northern Barents Sea and Arctic Ocean

    Get PDF
    Gelatinous zooplankton, here referring to the phylum Cnidaria and Ctenophora and the class Appendicularia are important components of marine ecosystems due to their very diverse diets, life cycles and seasonal dynamics. In the Barents Sea, several studies reviewed the gelatinous zooplankton diversity, yet few studies documented the diversity and distribution patterns between the advected Atlantic Waters (AW) and Polar waters (PW) and no study reviewed the gelatinous zooplankton seasonality over a full year. The aim of this master thesis is to (1) investigate diversity and distribution patterns between the different water masses and regions of the northern Barents Sea and (2) investigate the gelatinous zooplankton seasonality over a whole year in the northern Barents Sea. For this purpose, during the Nansen Legacy project four seasonal surveys covered the full seasonal cycle of the Barents Sea marginal ice zone and collected both biological and physical data, including gelatinous zooplankton. Overall, 31 gelatinous zooplankton taxa were identified. Fritillaria borealis, Oikopleura sp. and Aeginopsis laurentii were the most abundant taxa and AW and PW influenced areas had different seasonal dynamics and composition, which were significantly influenced by the primary production, the zooplankton biomass, the inflow of AW and the latitudes. Keywords: Gelatinous zooplankton, Barents Sea, Seasonality, Distribution, Atlantic Waters, Polar Waters, Nansen Legac

    The Politics of Platformization: Amsterdam Dialogues on Platform Theory

    What is platformization and why is it a relevant category in the contemporary political landscape? How is it related to cybernetics and the history of computation? This book tries to answer such questions by engaging in multidisciplinary dialogues about the first ten years of the emerging fields of platform studies and platform theory. It deploys a narrative and playful approach that makes use of anecdotes, personal histories, etymologies, and futurable speculations to investigate both the fragmented genealogy that led to platformization and the organizational and economic trends that guide nowadays platform sociotechnical imaginaries
