Challenging the empire

This paper considers how Paul Gilroy transformed hitherto dominant understandings of the relationship between race and class by developing an innovative account that foregrounded questions of racist oppression and collective resistance amid the organic crisis of British capitalism. The returns from this rethinking were profound in that he was able to make transparent both the structuring power of racism within the working class, and the necessity for autonomous black resistance. At the same time, significant lacunae in his account are identified, including the neglect of the episodic emergence of working-class anti-racism and the part played by socialists, particularly those of racialized minority descent in fashioning a major anti-racist social movement. The paper concludes with a lament for the disappearance of such work informed by a ‘Marxism without guarantees’ in the contemporary field of racism studies, and asks readers to consider the gains to be derived from such a re-engagement

Educational campaign to support pregnant women and new mothers in enjoying and benefiting from an active lifestyle. Insight report.

Recent research has shown that pregnant women who were physically active at the time of their booking appointment with a midwife (8-12 weeks) were most likely to initiate further discussion about maintaining their physical activity, however, it has also been found that there is a lack of consistent and clear information pertaining to physical activity messages with many health professionals either providing no such information or giving inappropriate guidance to women of childbearing age. A lack of training, knowledge, and resources regarding physical activity have resulted in healthcare professionals relying on common sense and their own experience to advise and guide pregnant women and new mothers. In turn, this often results in pregnant women and new mothers turning to informal sources, such as the internet, for guidance. In response, this project aims to develop a toolkit to support the delivery of consistent and clear messages regarding physical activity by healthcare professionals (in line with current guidance), as well as helping to stimulate engagement with physical activity in our target audiences. Through increasing the confidence, skills, and knowledge of healthcare professionals, it is expected that pregnant women and new mothers will be empowered to make informed physical activity choices throughout pregnancy and beyond. This report brings together the insights from the scoping activities carried out to facilitate the development of an educational campaign to support pregnant women and new mothers in enjoying and benefiting from an active lifestyle. The report provides an overview of the key themes that became apparent and conclude with points for discussion and next steps in the project delivery

Aggregation-Induced Emission Enhancement in Boron Difluoride Complexes of 3-Cyanoformazanates

Boron difluoride (BF2) complexes of 3-cyanoformazanates exhibit aggregation-induced emission enhancement in THF-water mixtures due to their severely twisted N-aryl substituents which restrict intramolecular motion and π stacking upon aggregation

Beyond Dexamethasone, Emerging Immuno-Thrombotic Therapies for COVID-19

Host immunity is required to clear SARS‐CoV‐2, and inability to clear the virus because of host or pathogen factors renders those infected at risk of poor outcomes. Estimates of those who are able to clear the virus with asymptomatic or paucisymptomatic COVID‐19 remain unclear, and dependent on widespread testing. However, evidence is emerging that in severe cases, pathological mechanisms of hyperinflammation and coagulopathy ensue, the former supported by results from the RECOVERY trial demonstrating a reduction in mortality with dexamethasone in advanced COVID‐19. It remains unclear whether these pathogenic pathways are secondary to a failure to clear the virus because of maladaptive immune responses or if these are sequential COVID‐19 defining illnesses. Understanding the pathophysiological mechanisms underpinning these cascades is essential to formulating rationale therapeutic approaches beyond the use of dexamethasone. Here, we review the pathophysiology thought to underlie COVID‐19 with clinical correlates and the current therapeutic approaches being investigated

Racism and anti-racism in Europe: a critical analysis of concepts and frameworks

The targets and expressions of racism vary across Europe. This article discusses the relevance of different descriptions and analyses of racism despite the different terms used in different countries such as ‘ethnic minority’, ‘foreigner’ or ‘black’ and different interpretations of which differences matter. It shows the significance of a cross-national European perspective on racism. There are important convergences across European countries in the discourses and practices of racism, particularly the distinction between ‘useful’ and ‘abusive’ migrants. A cross-European perspective can be an important inspiration for anti-racist struggles

Optoelectronic Properties of Carbon-Bound Boron Difluoride Hydrazone Dimers

The creation of dimeric boron difluoride complexes of chelating N-donor ligands is a proven strategy for the enhancement of the optoelectronic properties of fluorescent dyes. We report dimers based on the boron difluoride hydrazone (BODIHY) framework, which offer unique and sometimes unexpected substituent-dependent absorption, emission, and electrochemical properties. BODIHY dimers have low-energy absorption bands (lmax = 421 to 479 nm, e = 17,200 to 39,900 M−1 cm−1) that are red-shifted relative to monomeric analogues. THF solutions of these dimers exhibit aggregation-induced emission upon addition of water, with emission enhancement factors ranging from 5 to 18. Thin films of BODIHY dimers are weakly emissive as a result of the inner-filter effect, attributed to intermolecular p-type interactions. BODIHY dimers are redox-active and display two one-electron oxidation and two one-electron reduction waves that strongly depend on the N-aryl substituents. These properties are rationalized using density-functional theory calculations and X-ray crystallography experiments
