Why is exposure to political violence associated with both mobilising and demobilising outcomes? Community dynamics influence the local materialisation of violence engendered by supra-local political conflict. The reification of the driving political conflict as intracommunal or intergroup produces disparate outcomes. Exposure to violence may generate an enduring rift concretised through intimate bloodshed or could fashion a shared victimisation experience viable as a collective political mobilisation resource. In Cameroon, the Union des populations du Cameroun (UPC) opposed French colonialism through political action and guerilla warfare. Many saw the UPC as a heroic nationalist movement, others as murderers. Through interviews, I examine narratives that [re]construct social and political meaning out of conflict and death. These narratives of conflict are used to mobilise in places where the UPC was locally hegemonic and demobilise in politically competitive areas.
In recent times, the effects of climate change, the COVID-19 pandemic and other natural disasters have undermined global efforts to reduce poverty and inequality among rural farmers. While efforts at mitigating the impacts of climate change, particularly in developing countries, have not yielded significant improvements, the global health crises of the COVID-19 pandemic have, in many ways, undermined the positive adaptations to climate change. Based on data produced through mixed methods, the paper explores how COVID-19 affected farmers’ ability to adapt to the changing climatic conditions in Ghana’s Coastal and Guinea savannah ecological zones. The paper argues that the disruption caused by the COVID-19 pandemic has undermined farmers’ access to markets, knowledge, innovations, technologies and critical inputs such as fertilisers, seeds and weedicides/herbicides/pesticides. This has decreased farm output, increased post-harvest loss and increased farmers’ vulnerability to the adverse effects of climate change.
This article argues that environmental justice extends beyond planning and decision-making to include enforcement as a critical, yet often overlooked, dimension. It advances the claim that incorporating environmental justice into enforcement law and policy is essential for addressing structural inequalities and promoting accountability in environmental governance. The primary objective of the article is to identify environmental justice guidelines embedded in enforcement frameworks, with the aim of strengthening the role of justice in regulatory practice and enhancing the equity and effectiveness of enforcement outcomes. The analysis focuses on three enforcement tools that reflect a flexible and responsive approach: (i) the United States’ Supplemental Environmental Projects, (ii) the United Kingdom’s Environmental Enforcement Undertakings, and (iii) Chile’s Compliance Programmes. The article draws on three sources of data: case studies, the environmental justice guidelines applicable to them, and the existing state of enforcement. It begins by examining the regulatory design of enforcement systems in the three jurisdictions; it then analyzes each tool to identify how environmental justice dimensions are integrated – or could be integrated – into their design and implementation. Finally, it assesses the practical application of these instruments, arguing that the deliberate incorporation of environmental justice considerations can improve the responsiveness, transparency, and legitimacy of enforcement mechanisms, which ultimately benefits both the environment and affected communities.
This article examines diasporic Iranian responses to protests sparked by the death of Jina (Mahsa) Amini in September 2022. While Amini’s death galvanized widespread dissent inside Iran, it also spurred diasporic Iranian solidarity, often expressed through the call to “be the voice” of Iranian protestors. I analyze two key practices of diasporic narration: first, framing the Woman, Life, Freedom protests as a “revolution” in social media discourse; and second, the circulation of nostalgic video montages idealizing pre-1979 Iran as a lost era of political freedom. Together, these practices reveal how diasporic narratives may dilute protest demands by fitting them into revisionist frameworks. The conclusion reflects on both the potential and limits of diaspora narration in shaping political memory and understanding.
In this article, we address the role that European bordering and migration policy play in the broader construction of the European project by defining who does and does not belong in Europe. This question, and the policy answers to it, are shaped by a variety of different political and economic interests and factors, such as racialized narratives of border protection, labor market needs, and the securitization of borders. We tackle this question by examining the role that categories and figures of migration—such as the “genuine” and “bogus” asylum seeker, the refugee, and the economic migrant—play in European border policy and how they are changing in the present conjuncture. We argue that a redefinition is taking place of who counts as a “good” and “bad” migrant, which responds to the changing political economy of contemporary European capitalism and is reflected in the growing prominence of the dichotomy of “legal” and “illegal” migration. This, we argue, reconfigures the existing categories of economic migrant and asylum seeker and speaks to the emergence of new forms of racialized disposability at Europe’s borders. We do this by developing a critical political economy perspective that builds on our previous work and draws on the literature on racial capitalism and the concept of disposability.
The experiences of Latina women and girls with state surveillance, and their responses to unfair policies and practices, remain underexplored. Drawing on in-depth interviews with Latinas—primarily of Mexican descent—living in San Diego, we examine how encounters with local police and immigration enforcement shape their political practices. Participants described repeated negative encounters with police and immigration enforcement agencies over the life course. These cumulative experiences fostered distrust of police and critical views of surveillance practices designed to restrict the mobility of immigrants and other systematically minoritized groups. In response, many of the women engaged in community organizing and adopted counter-surveillance strategies. Our findings show how patterned experiences with state surveillance generate political critique and action.
This article examines the lived experiences of multiculturalism among the Indonesian migrant women living in South Korea through the lens of ‘everyday otherness’. The process experienced in this context is seen as part of a broader development of Korean multiculturalism. The article investigates how cultural encounters are perceived, interpreted, and negotiated by Indonesian migrant women. Drawing from qualitative research that dealt with migration narratives, the study aims to contribute to the ongoing discussion on Korean multiculturalism and identify areas for improvement. It argues that everyday otherness practices in Korea have become subtler, more nuanced, and multi-layered. It reveals that while everyday multicultural practices in Korea have become more welcoming the presence of foreigners, the daily experience of racism and otherness continues, and is even more confounding.
The propagation of linear waves in non-ideal compressible fluids plays a crucial role in numerous physical and engineering applications, particularly in the study of instabilities, aeroacoustics and turbulence modelling. This work investigates linear waves in viscous and heat-conducting non-ideal compressible fluids, modelled by the Navier–Stokes–Fourier equations and a fully arbitrary equation of state (EOS). The linearised governing equations are derived to analyse the dispersion relations when the EOS differs from that of an ideal gas. Special attention is given to the influence of non-ideal effects and various dimensionless numbers on wave propagation speed and attenuation. By extending classical results from Kovásznay (1953 J. Aeronaut. Sci. vol. 20, no. 10, pp. 657–674) and Chu (1965 Acta Mech. vol. 1, no. 3, pp. 215–234) obtained under the ideal gas assumption, this study highlights the modifications introduced by arbitrary EOSs to the linear wave dynamics in non-ideal compressible flows. This work paves the path for an improved understanding and modelling of wave propagation, turbulence and linear stability in arbitrary viscous and heat-conducting fluids.
The complex behaviour of air–liquid interfaces driven into Hele-Shaw channels at high speeds could arise from oscillatory dynamics; yet both the physical and dynamical mechanisms that lead to interfacial oscillations remain unclear. We extend the experiments by Couder et al. (1986, Phys. Rev. A, vol. 34, 5175) to present a systematic investigation of the dynamics that results when a small air bubble is placed at the tip of a steadily propagating air finger in a horizontal Hele-Shaw channel. The system can exhibit steady and oscillatory behaviours, and we show that these different behaviours each occur in well-defined regions of the phase space defined by flow rate and bubble size. For sufficiently large flow rates, periodic finger oscillations give way to disordered dynamics characterised by an irregular meandering of the finger’s tip. At fixed flow rate, the oscillations commence when the bubble size is increased sufficiently that the decreased curvature of the bubble tip in the horizontal plane matches that of the finger tip. This causes the axial pressure gradient along the bubble to vanish, thus rendering the bubble susceptible to lateral perturbations. Differing time scales for finger and bubble restoral allow sustained oscillations to develop in the finger–bubble system. The oscillations cease when the bubble is sufficiently large that it can act as the tip of a single finger. The disordered dynamics at high flow rates are consistent with the transient exploration of unstable periodic states, which suggests that similar dynamics may underlie disorder in viscous fingering.
Double-outlet right ventricle is a complex congenital cardiac anomaly in which both great arteries arise predominantly from the right ventricle. Accurate anatomical evaluation is critical for surgical planning. While transthoracic echocardiography is commonly used for intracardiac assessment, its limitations in visualising extracardiac structures highlight the need for additional imaging modalities like CT angiography.
Objective:
To compare the diagnostic accuracy and clinical utility of transthoracic echocardiography and CT angiography in the pre-operative evaluation and surgical planning of infants with double-outlet right ventricle.
Methods:
This retrospective, single-centre study included 78 infants diagnosed with double-outlet right ventricle. All patients underwent both transthoracic echocardiography and CT angiography before surgical intervention. Imaging findings were compared with intraoperative surgical results to assess sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy for each modality.
Results:
CT angiography was significantly more effective than transthoracic echocardiography in identifying extracardiac anomalies such as coronary artery anomalies (p = 0.014), aortic arch hypoplasia (p = 0.024), aortopulmonary collateral vessels (p = 0.039), anomalous pulmonary venous connections (p = 0.001), and persistent left superior vena cava (p = 0.001). In contrast, transthoracic echocardiography was more sensitive in detecting small ventricular septal defects (p = 0.035).
Conclusion:
Transthoracic echocardiography remains the first-line modality for intracardiac evaluation in double-outlet right ventricle, but CT angiography provides superior visualisation of extracardiac structures. The combined use of both imaging techniques improves diagnostic accuracy and surgical planning, supporting better outcomes in the management of CHD.
To determine the rate of healthcare personnel (HCP) glove or gown contamination with methicillin-resistant Staphylococcus aureus (MRSA) and to estimate which patient care interactions and HCP roles are associated with greater contamination.
Design:
Multicenter cohort study.
Setting:
Five Veterans Affairs medical centers in the United States.
Patients and participants:
Patients with a positive MRSA clinical or surveillance culture within the past 7 days were enrolled. Five HCP in the room were observed for each patient. After completion of tasks and prior to room exit, HCP gloves and gowns were cultured separately.
Results:
We enrolled 799 patients and obtained 3,832 glove and gown cultures. Contamination of HCP gloves or gown with MRSA occurred 713 of 3,832 (18.6%) of the time, while 589 of 3,832 (15.4%) of interactions resulted in contamination of gloves, and 319 of 3,831 (8.3%) of interactions resulted in contamination of gowns. The gloves and gowns of physical therapists and occupational therapists were most frequently contaminated. Any interactions that involved touching the patient resulted in glove or gown contamination in 622 of 2,901 (21.4%) of observations, while touching only the environment resulted contamination in 91 of 931 (9.8%) of observations. Rates of glove or gown contamination were similar in the intensive care unit (ICU) and non-ICU.
Conclusions:
Contamination of HCP gloves and gowns with MRSA occurs frequently when caring for Veteran patients particularly when there is direct patient contact. Hospitals may consider optimizing contact precautions by using fewer precautions for low-risk interactions and more precautions for high-risk interactions.
This article deals with the reception of the Yugoslav model of self-management in Italy between the 1950s and 1970s. Drawing on a wide range of archival sources from Yugoslav and Italian archives, this research provides new evidence about transnational exchanges of models of industrial democracy that transcended ideological barriers and the Cold War divide and linked Italian party elites, trade unions and Christian-oriented movements to the ‘Yugoslav model’ in a common search for a ‘third way’ in industrial relations.
Scimitar syndrome is characterised by anomalous right pulmonary venous drainage to the inferior vena cava associated with right pulmonary artery hypoplasia. We present a case of an infant with Scimitar syndrome with a well-formed right pulmonary artery, in high Qp heart failure who was managed with right pulmonary artery banding after thorough haemodynamic evaluation.
