‘King Solomon’s mines cannot compare with the money that has been raked in by greyhound racing’: Greyhound racing, its critics and the working class, c. 1926 to 1951.

Greyhound racing emerged in Britain in 1926 and, during its first quarter of a century, was subject to institutional middle-class opposition because of the legal gambling opportunities it offered to the working class. Much maligned as a dissipate and impoverishing activity it was in fact a significant leisure opportunity for the working class, which cost little for the minority of bettors involved in what was clearly no more than a ‘bit of a flutter’

Banning diesel vehicles in London: Is 2040 too Late?

Air pollution contributes to 9400 deaths annually in London and diesel vehicles are considered a major source of lethal air pollutants. Consequently, the UK government announced its intention to ban diesel vehicles by 2040 to achieve a sustainable zero-carbon road transport system. Since no empirical studies have used a bottom-up approach to seek Londoners’ views, it is therefore worth investigating the public opinion regarding this forthcoming ban. This paper aims to fill this research gap by taking London as a case study. A survey was designed, and fieldwork was conducted to distribute questionnaires to Londoners. Completed questionnaires were analysed using both quantitative and qualitative methods. The findings revealed that the majority of Londoners would be in favour of the ban if they were sufficiently exposed to the appropriate sources of information and were favourably disposed towards environmental protection measures. The results also showed that Londoners were more likely to switch to electric vehicles (EVs) if they were offered generous incentives and encouraged to use scrappage schemes. The present study makes a strong case for enforcing the ban well before 2040. The significance of this research is to provide clearer signals regarding the future of diesel vehicles, which in turn will strengthen the EV policy and uptake

Greenland Ice Sheet exports labile organic carbon to the Arctic oceans

Runoff from small glacier systems contains dissolved organic carbon (DOC) rich in protein-like, low molecular weight (LMW) compounds, designating glaciers as an important source of bioavailable carbon for downstream heterotrophic activity. Fluxes of DOC and particulate organic carbon (POC) exported from large Greenland catchments, however, remain unquantified, despite the Greenland Ice Sheet (GrIS) being the largest source of global glacial runoff (ca. 400 km3 yr−1). We report high and episodic fluxes of POC and DOC from a large (> 600 km2) GrIS catchment during contrasting melt seasons. POC dominates organic carbon (OC) export (70–89% on average), is sourced from the ice sheet bed, and contains a significant bioreactive component (9% carbohydrates). A major source of the “bioavailable” (free carbohydrate) LMW–DOC fraction is microbial activity on the ice sheet surface, with some further addition of LMW–DOC to meltwaters by biogeochemical processes at the ice sheet bed. The bioavailability of the exported DOC (26–53%) to downstream marine microorganisms is similar to that reported from other glacial watersheds. Annual fluxes of DOC and free carbohydrates during two melt seasons were similar, despite the approximately two-fold difference in runoff fluxes, suggesting production-limited DOC sources. POC fluxes were also insensitive to an increase in seasonal runoff volumes, indicating a supply limitation in suspended sediment in runoff. Scaled to the GrIS, the combined DOC (0.13–0.17 TgC yr−1 (±13 %)) and POC fluxes (mean = 0.36–1.52 TgC yr−1 (±14 %)) are of a similar order of magnitude to a large Arctic river system, and hence may represent an important OC source to the near-coastal North Atlantic, Greenland and Labrador seas

Emotions in the laboratory

The ability to temporarily hold information in visual working memory (VWM) is an important cognitive function as it is not only crucial in everyday life but also in other domains, such as educational settings and academic performance (Alloway & Alloway, 2010; Conway et al., 2003; Epelboim & Suppes, 2001; Fukuda et al., 2010). Even though VWM has been shown to be a stable construct in general, it can be influenced by other factors. For instance, previous research has demonstrated that emotional states or emotional stimuli can influence VWM performance (e.g. Spachtholz et al., 2014; Xie & Zhang, 2016). However, up to date there is a striking lack of research on whether a VWM task, which is used to measure VWM, may induce emotional experiences itself, and whether they in turn affect VWM performance. Some authors have speculated that a standard VWM task arouses emotions in participants and that these task-induced emotions are related to VWM performance (Luck, 2014; Rouder et al., 2008). The aim of the present thesis was therefore to establish if and how emotions, should they occur because of the VWM task itself, are linked with individuals’ VWM performance. To meet this objective an interdisciplinary approach was taken and well-established findings from educational psychology were applied to a core cognitive research question, namely that of VWM. In a first qualitative study (N=19), by adapting a qualitative method of inquiry, the think-aloud technique (van Someren et al., 1995), results revealed that the task induced different positive and negative emotions, such as joy and anger, which varied on the inter-individual as well as on the intra-individual level. The emotional experiences seemed to be tied to the implicit achievement requirement of the VWM task (getting it right vs. wrong; Elliot et al., 2017). To investigate whether these task-induced emotions were linked to VWM performance, two quantitative studies (N = 45, and N = 41, respectively) were carried out. Here, findings revealed that VWM performance was positively linked to joy, and negatively linked to anger, frustration and boredom on the inter-individual and intra-individual level. Notably, these emotions were also affected by an experimental manipulation of task difficulty (set size 4 vs. 8). This research is the first to demonstrate that a task designed to measure VWM in itself triggers emotions, specifically achievement emotions (e.g. Pekrun, 2006), which, in turn, are linked with VWM performance. The findings from the studies highlight the relevance of achievement emotions as potentially confounding variables for interpreting VWM scores as resulting from typical laboratory-based paradigms for measuring VWM capacity. Given the relevance of these findings for research on VWM, cognitive research in general and other fields of research in which VWM plays a role, for example academic performance, another aim of the present thesis was to consider further factors, such as achievement goal orientation, which may affect the link between task-induced achievement emotions during a VWM task, and VWM performance. Therefore, a registered report was designed which aims to replicate and further explore the findings from Studies 1 through 3 on the one hand and on the other hand consider the role of further variables in the achievement-emotion-VWM-relationship. Specifically, it is hypothesized (1) that task-induced achievement emotions will correlate with VWM performance and that this link is (2) mediated by subjective task performance (i.e. how well or poorly participants think they are doing on the VWM task). Further, as goal orientation is thought to be strongly related to achievement emotions (Pekrun et al., 2006), it is hypothesized (3) that the emotion-performance links are moderated by performance goal orientation. Finally, it is hypothesized (4) that achievement emotions, performance goal orientation, and task difficulty interact in predicting VWM. N = 225 participants will be recruited to perform the continuous color-report task. Participants’ achievement emotions and subjective task performance will be obtained by self-report after the VWM task. It is expected that the findings from the registered report will further highlight the relevance of achievement emotions as a potentially confounding variable for interpreting an individual’s VWM ability

Network formation mechanisms in conjugated microporous polymers

We discuss in detail the mechanism of formation of a highly microporous polymer, CMP-1, formed mainly via Sonogashira–Hagihara coupling. We demonstrate how the microporosity evolves with time, and discuss the importance of alkyne homo-coupling on the microporosity
