This brief note corrects an aspect of our 2024 paper looking at the evidence for the route of the Dorchester aqueduct in which we attributed a previously hypothesised route for the aqueduct to Christopher Sparey-Green.
Cue-reactivity responses in addictive behaviours are triggered by cues associated with the addictive activity itself. Although such cues may depict the rewarding aspects of the behaviour, responses may also generalise to more distal cues that do not directly convey this content.
Aims
To examine cue reactivity to distal cues (i.e. devices displaying starting or log-in screens of internet applications) in a diagnostically validated sample of individuals with specific problematic usage of the internet (PUIs) and determine whether laboratory-measured cue reactivity predicts real-life behavioural engagement and temptation experiences, in addition to differences across PUI stages and cue types.
Method
In this preregistered study, data were collected from October 2021 to 31 August 2024 from individuals with non-problematic (n = 268), risky (n = 135) and pathological (n = 133) engagement in specific internet activities (gaming, buying and/or shopping, pornography use and social networking). Participants were aged 18–65 years (mean age 26.12 years, s.d. 6.79), and 44.6% were female. A cue-reactivity paradigm with distal cues showing target and non-target internet activities was used. A within–between participants design was used, with repeated measures analyses of variance. Correlations between laboratory cue-reactivity measures and measures from a 14-day end-of-day assessment in the natural environment are reported.
Results
Heightened cue reactivity (arousal, urge and/or craving) was observed in individuals with risky and pathological use compared with those with non-problematic use across all levels of the paradigm. Individuals with pathological use showed elevated levels of urge and craving, along with generalised responses to stimuli showing starting and/or log-in screens not related to their specific (addictive) behaviour. These effects were consistent across different types of PUI and were associated with engagement in the behaviour and temptation experiences in naturalistic settings.
Conclusions
These findings indicate that cue reactivity and craving are central aspects of PUIs. Although different devices may elicit different types of action, our results highlight the challenges of regulating behaviour in environments saturated with unavoidable triggers, such as internet content and devices.
This article explores the variation surrounding the semi-modals be going to and gonna. While gonna is frequently mentioned alongside be going to, it remains under-described in traditional grammars and academic literature. However, recent studies within Construction Grammar suggest that gonna may represent an independent construction, prompting a reconsideration of other variants within the be going to / gonna paradigm such as gon and imma, which appear to derive directly from gonna and no longer from be going to. In light of recent work, what have traditionally been regarded as mere ‘phonetic realizations’ or ‘orthographic variants’ may in fact play a more significant role in the formation and definition of constructions, raising questions about the structure of constructional networks. This article analyzes the immediate syntactic environment of the variants to account for both the variation of forms and the status of such forms. The study is conducted using two corpora that are particularly prone to showing linguistic innovations and language change: a spontaneous spoken corpus and a web corpus. Findings indicate that shorter variants often involve elision of be and that gonna is more grammaticalized than going to, based on the types of verbs they precede.
This paper builds on a thought experiment by Professor Harry van Buren, asking what might emerge if the Business and Human Rights field took a temporary ‘break’ from the UN Guiding Principles (UNGPs). It critically analyzes how the UNGPs’ pragmatic and consensus-oriented design, while instrumental in institutionalizing the field, has also shifted its normative orientation. The paper argues that the increasing dominance of procedural pragmatism has led to compliance-driven approaches that risk displacing more justice-oriented, participatory visions of accountability. In response, the paper aims to contribute to potential reimagining of the field outside of the confines of the UNGPs by offering an alternative pathway grounded in Critical Dialogic Accounting and Accountability, Worker-driven Social Responsibility, and prefigurative politics. The paper concludes with a reflection that the future of BHR depends not just on expanding the implementation of existing norms but on rethinking what accountability can look like when built from below.
Plastic pollution in our aquatic systems is a pressing issue, and the spread of these particles is determined by several factors. In this study, the advection and dispersion of negatively buoyant finite-size particles of four different shapes (spheres, circular cylinders, square cylinders and flat cuboids) and two sizes (6 and 9 mm) are investigated in turbulent open-channel flow. The volume, mass and characteristic length are fixed for each size. Four different turbulent conditions are considered, varying the free stream velocity $U_{\infty }=$ 0.25 and 0.38 m s–1 and turbulence intensity ($(u'/U)_\infty =4$ % and 9 %). The particles are released individually from below the water surface. A catch-grid is placed along the bottom floor to mark the particle landing location. The average particle advection distance remains unchanged between the turbulence levels, suggesting that the mean settling velocity is independent of turbulence in this regime. Based on the root mean square of the landing locations, the particle dispersion varies with particle shape, size, settling velocity and turbulent flow conditions. For the square cylinders investigated in this work, the effect of particle shape on dispersion is difficult to predict at low flow velocities and turbulence intensities. As the turbulent fluctuations increase, the dispersion becomes more predictable for all shapes. An empirical expression is proposed to relate turbulent velocity fluctuations, integral length scales, particle settling velocity and particle size to streamwise dispersion. It is found that finite-size inertial particles do not disperse per simple turbulent diffusion, meaning that particle geometry has to be incorporated into dispersion models.
A theoretical model is developed to study the deformation dynamics of a biconcave red blood cell (RBC) in a viscous fluid driven by an ultrasonic standing wave. The model considers the true physiological shape of RBCs with biconcave geometry, overcoming the challenges of modelling the nonlinear acoustomechanical coupling of complex biconcave curved shells. The hyperelastic shell theory is used to describe the cell membrane deformation. The acoustic perturbation method is employed to divide the Navier–Stokes equations for viscous flows into the acoustic wave propagation equation and the mean time-averaged dynamic equation. The time-average flow–membrane interaction is considered to capture the cell deformation in acoustic waves. Numerical simulations are performed using the finite element method by formulating the final governing equation in weak form. And a curvature-adaptive mesh refinement algorithm is specifically developed to solve the error problem caused by the nonlinear response of biconcave boundaries (such as curvature transitions) in fluid–structure coupling calculations. The results show that when the acoustic input is large enough, the shape of the cell at the acoustic pressure node changes from a biconcave shape to an oblate disk shape, thereby predicting and discovering for the first time the snap-through instability phenomenon in bioncave RBCs driven by ultrasound. The effects of fluid viscosity, surface shear modulus and membrane bending stiffness on the deformation of the cell are analysed. This numerical model has the ability to accurately predict the acoustic streaming fields and associated time-averaged fluid stress, thus providing insights into the acoustic deformation of complex-shaped particles. Given the important role of the mechanical properties of RBCs in disease diagnosis and biological research, this work will contribute to the development of acoustofluidic technology for the detection of RBC-related diseases.
This article employs the satellite as a methodological lens to reconceptualize China’s Great Leap Forward, investigating this movement as an aesthetic crusade rather than a mere cause of political and economic pandemonium. Emerging as the movement’s most prevalent entity, the satellite underwent protean transformations—from an epitome of the Cold War to an emblem of socialist utopia, from its initial embodiment in popular science books to its embedment in mythologies, and from a contagious trope in bureaucratese to the most indispensable constituent in the creation of arts for the masses. Nevertheless, due to its belated materialization, the satellite emerged not as other socialist objects whose materiality was taken as a given, but as an object-yet-to-be-made, one that best articulates the paradoxes of Maoist material abundance, likewise suspended between fantasy and fulfilment. In this light, I argue that the satellite becomes a ‘thing’, one that exceeds its physicality, exploits the agency of words, and gained regulative potency. Drawing on newspapers, memoirs, operas, poems, folksongs, and visuals, I delineate the satellite’s encounters with politicians, cadres, writers, peasants, and workers, mapping its sanctification into a fetishized object that encapsulates Maoist China’s struggles, with its ideological contests, political visions, historical legacies, and class conflicts.
Religious and ethnic communities have long helped people cope with risks. Does state-provided welfare substitute for ethnicity-based social insurance? If so, does it improve intergroup relations? Ethnicity-based insurance operates through reciprocity and solidarity, requiring social investment in in-group ties. This limits the formation of out-group ties, exacerbating ethnic divisions. Welfare reduces dependence on the ethnic group, allowing individuals to form productive out-group ties and increasing intergroup integration. I test this argument in caste networks in India. I leverage panel data on household loans to show that an income support program reduced within-caste borrowing by 38.5%. Using survey data from 3,020 households, I show that welfare enhanced intercaste ties, mainly in areas with lower caste-based land inequality. I draw on 56 qualitative interviews to document how caste-based social insurance exacerbates social segregation, and why intercaste ties increase with lower group inequality. These findings illuminate the persistence and demise of ethnic divisions.
The emergence of ‘compassionate cities’ and ‘compassionate communities’ (CCC) as social movements has become a pronounced development in public health approaches to the end-of-life. Drawing on the World Health Organisations’ Ottawa Charter, it contends that end-of-life care has become individualised and medicalised and promotes the ‘rediscovery’ of community approaches. Drawing on a range of sociological theory insights, it deploys a ‘critical interpretative’ analytic approach to literature identified in a narrative review. The paper aims to question the affirmative consensus that exists around CCC by building on the emergence of critical themes have recently emerged in various meta-reviews. This analysis identifies tensions and inconsistencies between the ideals of The Ottawa Charter, CCC practice and a relatively superficial and uncritical deployment of theory, particularly in relation to its status as a conservative or radical movement. The paper concludes by suggesting constructive ways forward.
This article examines the evolving landscape of accounting, distinguishing between mainstream practices and critical developments that challenge conventional notions of accounting and accountability. By engaging with perspectives that reimagine accounting’s role, the paper highlights how rights intersect with accounting practices and how accounting, in turn, shapes rights. While financial and non-financial disclosures can expose human rights abuses, concerns persist over ‘accountability-washing’ and the dominance of economic interests. The reluctance of standard-setting bodies, such as the International Sustainability Standards Board, to integrate human rights underscores the political and institutional barriers to change. The article concludes by exploring future research directions through which business and human rights scholars and critical accounting researchers can mutually benefit from each other’s insights.
While abortion has been a contentious and salient political issue in the United States for decades, the debate around abortion has evolved in terms of the rhetorical frames employed by advocates on both sides. Using vignettes of statements made by hypothetical lawmakers, we evaluate responsiveness to some of these emergent frames. Specifically, we evaluate “pro-woman” framing employed by pro-life advocates, which positions abortion restrictions as being in the interests of women. The experiment also manipulates to whom the frame is attributed in two ways, the gender and the partisanship of the lawmaker. This 2 × 2 × 2 experiment explores the intersection of how abortion restrictions are framed, including the roles gender and partisanship in the persuasiveness of the frames. We find that voters are more receptive to the pro-woman frame compared to the classic fetal rights framing. Importantly, this holds even among supporters of abortion rights, casting substantial light on persuadable groups.
Political myths, the sacred narratives that legitimize power, are at the core of all political communities and organizations. In the post–World War II era, clear myths emerged around the ordering of the world, placing democracy, order, and peace at the idealized heart of global governance. Today, the international order is markedly changed. Previously dominant myths are routinely questioned and the international order that was built on these myths is beginning to fragment. Myths traditionally change with institutions. At this unique inflection point in the 2020s, however, this is no longer the case—myths crumble while the institutions they once supported persist, creating a vacuum in which novel myths must emerge in what we refer to as the new age of myth. We argue that the global order is in a transitional moment in terms of its governing mythologies. The myths that are born out of this age will underline the institutions, ideas, and ideologies that will shape the trajectory of the international order in the coming decades. In this essay we therefore argue that the study of political myths should be central to future approaches to international relations. Such an emphasis not only provides insight into the pathways of international cooperation and politics that may emerge from the contemporary shattering of the global political order, but also highlights how these sacred narratives will shape its future trajectory.
We study sums of squares of integers except for a fixed one. For any nonnegative integer n, we find the minimum number of squares of integers except for n whose sums represent all positive integers that are represented by a sum of squares except for n. This problem could be considered as a generalisation of the result of Dubouis [‘Solution of a problem of J. Tannery’, Intermédiaire Math.18 (1911), 55–56] for the case when $n=0$.
Strategic litigation has emerged as a prominent tool in the business and human rights (BHR) field, offering a pathway to promote corporate accountability, test innovative legal arguments and push for systemic change. While often framed as private tort actions, such litigation frequently aims to shape broader norms beyond individual remedies. This article explores how strategic litigation contributes to the evolution of corporate responsibility to respect human rights by analysing two case studies: supply chain liability claims in English courts and corporate climate litigation in the Netherlands. Drawing on these examples, the article argues that, despite its limitations, strategic BHR litigation plays an important role in translating soft law standards, including the UN Guiding Principles on Business and Human Rights, into enforceable legal duties.
