This article situates the potential for intellectual work to be renewed through an enriched engagement with the relationship between indigenous protocols and artificial intelligence (AI). It situates ...this through a dialectical storytelling of the contradictions that emerge from the relationships between humans and capitalist technologies, played out within higher education. It argues that these have ramifications for our conceptions of AI, and its ways of knowing, doing and being within wider ecosystems. In thinking about how technology reinforces social production inside capitalist institutions like universities, the article seeks to refocus our storytelling around mass intellectuality and generative possibilities for transcending alienating social relations. In so doing, the focus shifts to the potential for weaving new protocols, from existing material and historical experiences of technology, which unfold structurally, culturally and practically within communities. At the heart of this lies the question, what does it mean to live? In a world described against polycrisis, is it possible to tell new social science fictions, as departures towards a new mode of higher learning and intellectual work that seeks to negate, abolish and transcend the world as-is?
This article challenges a liberal analysis of higher education (HE) inside an integrated system of economic production, and instead critiques: first, how UK policymakers sought to re-engineer English ...HE during and after the pandemic, through governance, regulation and funding changes predicated upon accelerating a discourse of value-for-money; second, the institutional labour reorganisation that followed, and which placed complete class fractions of academic labour in a permanent state of being at risk; and third, how in continually demonstrating that it cannot fulfil the desires of those who labour within it for a meaningful work-life, the university must be transcended. In addressing the entanglement of precarity and privilege, it argues that, if the university is unable to contribute to ways of knowing, being and doing that address socio-economic, socio-environmental or intersectional ruptures, then it must go.
We provide an updated analysis of instrumental Greenland monthly temperature data to 2019, focusing mainly on coastal stations but also analysing ice‐sheet records from Swiss Camp and Summit. ...Significant summer (winter) coastal warming of ~1.7 (4.4)°C occurred from 1991–2019, but since 2001 overall temperature trends are generally flat and insignificant due to a cooling pattern over the last 6–7 years. Inland and coastal stations show broadly similar temperature trends for summer. Greenland temperature changes are more strongly correlated with Greenland Blocking than with North Atlantic Oscillation changes. In quantifying the association between Greenland coastal temperatures and Greenland Ice Sheet (GrIS) mass‐balance changes, we show a stronger link of temperatures with total mass balance rather than surface mass balance. Based on Greenland coastal temperatures and modelled mass balance for the 1972–2018 period, each 1°C of summer warming corresponds to ~(91) 116 Gt·yr−1 of GrIS (surface) mass loss and a 26 Gt·yr−1 increase in solid ice discharge. Given an estimated 4.0–6.6°C of further Greenland summer warming according to the regional model MAR projections run under CMIP6 future climate projections (SSP5‐8.5 scenario), and assuming that ice‐dynamical losses and ice sheet topography stay similar to the recent past, linear extrapolation gives a corresponding GrIS global sea‐level rise (SLR) contribution of ~10.0–12.6 cm by 2100, compared with the 8–27 cm (mean 15 cm) “likely” model projection range reported by IPCC in 2019 (SPM.B1.2). However, our estimate represents a lower limit for future GrIS change since fixed dynamical mass losses and amplified melt arising from both melt‐albedo and melt‐elevation positive feedbacks are not taken into account here.
We present an updated analysis of coastal and inland Greenland surface air temperature records, focusing on seasonal temperature trends and correlations with key indices of atmospheric circulation change and changes in ice‐sheet mass balance, and the 2019 high‐melt summer. By quantifying the relation between observed and projected Greenland surface air temperature changes and modelled ice‐sheet mass balance changes, we underscore the likely high sensitivity of the ice sheet to continued global warming, and provide predictions of GrIS surface mass balance change.
ABSTRACT
We present an extended monthly and seasonal Greenland Blocking Index (GBI) from January 1851 to December 2015, which more than doubles the length of the existing published GBI series. We ...achieve this by homogenizing the Twentieth Century Reanalysis version 2c‐based GBI and splicing it with the NCEP/NCAR Reanalysis‐based GBI. For the whole time period, there are significant decreases in GBI in autumn, October and November, and no significant monthly, seasonal or annual increases. More recently, since 1981 there are significant GBI increases in all seasons and annually, with the strongest monthly increases in July and August. A recent clustering of high GBI values is evident in summer, when 7 of the top 11 values in the last 165 years – including the two latest years 2014 and 2015 – occurred since 2007. Also, 2010 is the highest GBI year in the annual, spring, winter and December series but 2011 is the record low GBI value in the spring and April series. Moreover, since 1851 there have been significant increases in GBI variability in May and especially December. December has also shown a significant clustering of extreme high and low GBI values since 2001, mirroring a similar, recently identified phenomenon in the December North Atlantic Oscillation index, suggesting a related driving mechanism. We discuss changes in hemispheric circulation that are associated with high compared with low GBI conditions. Our GBI time series should be useful for climatologists and other scientists interested in aspects and impacts of Arctic variability and change.
Abstract Objective This article looks at lessons learned from the 1995 Kikwit Ebola outbreak and suggests how modern hospitals should apply these lessons to the next lethal viral epidemic that ...occurs. Method The 1995 Kikwit Ebola outbreak in the Democratic Republic of the Congo (formally Zaire) is one of the most well studied epidemics to have occurred to date. Many of the lessons learned from identifying, containing and treating that epidemic are applicable to future viral outbreaks, natural disasters and bioterrorist attacks. This is due to Ebola's highly contagious nature and high mortality rate. Results When an outbreak occurs, it often produces fear in the community and causes the basic practice of medicine to be altered. Changes seen at Kikwit included limited physical examinations, hesitance to give intravenous medications and closure of supporting hospital facilities. The Kikwit Ebola outbreak also provided beneficial psychological insight into how patients, staff and the general community respond to a biological crisis and how this will affect physicians working in an epidemic. Conclusions General lessons from the outbreak include the importance of having simple, well-defined triage procedures; staff who are flexible and able to adapt to situations with unknowns; and the need to protect staff physically and emotionally to ensure a sustained effort to provide care.
ABSTRACT
UK seasonal mean temperature and precipitation conditions are extremely variable from one year to the next but in the last decade have featured several cool, wet summers and mild, wet ...winters interspersed with some notable cold winter episodes. Jet stream variability is a major determinant of these fluctuations and is often represented by the North Atlantic Oscillation (NAO) index. Recent work has shown some evidence of promising predictability in the winter NAO from 1 to 2 months ahead, while summer predictability remains very limited. Although the phase and magnitude of the NAO influences total UK rainfall, there are regional variations which it does not explain. Here we examine the relationship between UK regional summer and winter precipitation and temperature and a range of North Atlantic atmospheric circulation indices. While the NAO shows a significant relationship with temperature in both seasons and summer rainfall over most of the UK, the picture in winter is more complicated, with other circulation indices such as the East Atlantic pattern explaining rainfall anomalies in southern England. Other indices also show significant relationships with precipitation in regions where the NAO does not. Because UK weather is determined by the interplay between different circulation indices, attention should be given to developing seasonal forecasts of other circulation indices to complement the NAO forecasts. We also find that some potential drivers of jet stream variability are significantly associated with UK temperature and rainfall variability, particularly in summer. This provides further scope for producing seasonal forecasts based directly on these drivers. Improved seasonal forecasts will be useful to a range of end users in agriculture, energy supply, transport and insurance industries and can be extended to other UK weather variables such as extreme rainfall events and storm frequency, and related metrics such as wind power capacity and solar energy.
The winter North Atlantic Oscillation is predictable from a few months ahead, but does not explain all regional UK precipitation and temperature anomalies. We examine associations between a number of circulation indices and UK summer and winter temperature and rainfall patterns. The East Atlantic and Scandinavian patterns explain significant regional variations in UK weather, and some drivers of summer jet stream variability are directly associated with summer temperature and precipitation variability. There is potential to develop improved regional seasonal forecasts.
Pedophilia has become a topic of increased interest, awareness, and concern for both the medical community and the public at large. Increased media exposure, new sexual offender disclosure laws, Web ...sites that list the names and addresses of convicted sexual offenders, politicians taking a “get tough” stance on sexual offenders, and increased investigations of sexual acts with children have increased public awareness about pedophilia. Because of this increased awareness, it is important for physicians to understand pedophilia, its rate of occurrence, and the characteristics of pedophiles and sexually abused children. In this article, we address research that defines the various types and categories of pedophilia, review available federal data on child molestation and pornography, and briefly discuss the theories on what makes an individual develop a sexual orientation toward children. This article also examines how researchers determine if someone is a pedophile, potential treatments for pedophiles and sexually abused children, the risk of additional sexual offenses, the effect of mandatory reporting laws on both physicians and pedophiles, and limitations of the current pedophilic literature.
Higher education in the UK is in crisis. The idea of the public university is under assault, and both the future of the sector and its relationship to society are being gambled. Higher education is ...increasingly unaffordable, its historic institutions are becoming untenable, and their purpose is resolutely instrumental. What and who has led us to this crisis? What are the alternatives? To whom do we look for leadership in revealing those alternatives? This book critically analyses intellectual leadership in the university, exploring ongoing efforts from around the world to create alternative models for organizing higher education and the production of knowledge. Its authors offer their experience and views from inside and beyond the structures of mainstream higher education, in order to reflect on efforts to create alternatives. In the process the volume asks: is it possible to re-imagine the university democratically and co-operatively? If so, what are the implications for leadership not just within the university but also in terms of higher education’s relationship to society? The authors argue that mass higher education is at the point where it no longer reflects the needs, capacities and long-term interests of global society. An alternative role and purpose is required, based upon ‘mass intellectuality’ or the real possibility of democracy in learning and the production of knowledge.
As one response to the secular crisis of capitalism, higher education is being proletarianised. Its academics and students, increasingly encumbered by precarious employment, debt, and new levels of ...performance management, are shorn of autonomy beyond the sale of their labour-power. Incrementally, the labour of those academics and students is subsumed and re-engineered for value production, and is prey to the twin processes of financialisation and marketisation. At the core of understanding the impact of these processes and their relationships to the reproduction of higher education is the alienated labour of the academic. The article examines the role of alienated labour in academic work in its relationship to the proletarianisation of the University, and relates this to feelings of hopelessness, in order to ask what might be done differently. The argument centres on the role of mass intellectuality, or socially-useful knowledge and knowing, as a potential moment for overcoming alienated labour.
Abstract
Individuals experience heterogeneous environmental conditions that can affect within-host processes such as immune defense against parasite infection. Variation among individuals in parasite ...shedding can cause some hosts to contribute disproportionately to population-level transmission, but we currently lack mechanistic theory that predicts when environmental conditions can result in large disease outbreaks through the formation of immunocompromised superspreading individuals. Here, I present a within-host model of a microparasite’s interaction with the immune system that links an individual host’s resource intake to its infectious period. For environmental scenarios driving population-level heterogeneity in resource intake (resource scarcity and resource subsidy relative to baseline availability), I generate a distribution of infectious periods and simulate epidemics on these heterogeneous populations. I find that resource scarcity can result in large epidemics through creation of superspreading individuals, while resource subsidies can reduce or prevent transmission of parasites close to their invasion threshold by homogenizing resource allocation to immune defense. Importantly, failure to account for heterogeneity in competence can result in under-prediction of outbreak size, especially when parasites are close to their invasion threshold. More generally, this framework suggests that differences in conditions experienced by individual hosts can lead to superspreading via differences in resource allocation to immune defense alone, even in the absence of other heterogeneites such as host contacts.
