Picture this: researching child workers

Visual methods such as photography are under-used in the active process of sociological research. As rare as visual methods are, it is even rarer for the resultant images to be made by rather than of research participants. Primarily, the paper explores the challenges and contradictions of using photography within a multi-method approach. We consider processes for analysing visual data, different ways of utilising visual methods in sociological research, and the use of primary and secondary data, or, simple illustration versus active visual exploration of the social. The question of triangulation of visual data against text and testimony versus a stand-alone approach is explored in depth

The divergence of bank lending rates from policy rates after the financial crisis: The role of bank funding costs

After the global financial crisis, policy rates were cut to near-zero levels, yet, bank lending rates did not fall as much as the decline in policy rates would have suggested. If the crisis represents a structural break in the relationship between monetary policy and lending rates, how should central banks view the post-crisis transmission? This poses a major puzzle for monetary policymakers. Using a new weighted average cost of liabilities to measure banks’ effective funding costs we show a model of interest rate pass-through with dynamic panel data methods solves this puzzle, and has many other advantages over traditional approaches. It confirms central banks should focus on the cost and composition of bank liabilities, as many are now doing, to better understand and steer the dynamics of lending rates

Grassland Management Practices and the Diversity of Soil Nematode Communities

Nematodes are numerically abundant in northern temperate grassland soils where, through their feeding on plants, soil microbes and each other as well as being a food resource, they contribute to soil functioning and affect plant soil interrelationships. Permanent plant cover and the consequent abundance of root tissue supply a year-round food supply. There are only limited data on the effects of root-feeding by nematodes on the growth and development of pasture plants but under some circumstances above-ground biomass may be reduced. Herbivory by specific nematode parasites may not only directly affect the host plant but also promote soil microbial activity and nutrient fluxes. Nematodes in other feeding groups interact directly with the microbial communities influencing soil processes, including decomposition and mineralisation

Massive maxillary radicular cyst presenting as facial fracture and abscess, a case report

Radicular cysts arise from non-vital teeth. They are inflammatory in nature and are the most common cystic lesion found in the jaw. We present a case of a massive maxillary radicular cyst in a 20 year-old man, diagnosed following an alleged assault and facial fracture. Subsequent abscess formation was initially thought to be infection secondary to haematoma due to fracture, but further investigation showed that it was to be due to a massive cyst

Southern Greenland glaciation and Western Boundary Undercurrent evolution recorded on Eirik Drift during the late Pliocene intensification of Northern Hemisphere glaciation

This is the author accepted manuscript. The final version is available from Elsevier via the DOI in this record.We present new sedimentological and environmental magnetic records spanning ~3.2–2.2 Ma, during the intensification of Northern Hemisphere glaciation, from North Atlantic Integrated Ocean Drilling Program Site U1307 on Eirik Drift. Our new datasets and their high-fidelity age control demonstrate that while inland glaciers – and potentially also at times restricted marine-terminating ice-caps – have likely existed on southern Greenland since at least ~3.2 Ma, persistent and extensive marine-terminating glacial margins were only established in this region at 2.72 Ma, ~300 kyr later than in northeastern and eastern Greenland. Despite a dramatic increase in Greenland-sourced ice-rafted debris deposition on Eirik Drift at this time, contemporaneous changes in the bulk magnetic properties of Site U1307 sediments, and a reduction in sediment accumulation rates, suggest a decrease in the delivery of Greenland-sourced glaciofluvial silt, which we attribute to a shift in depositional regime from bottom-current-dominated to glacial-IRD- dominated between ~2.9–2.7 Ma in response to a change in the depth of the flow path of the Western Boundary Undercurrent relative to our study site

Catalyst‐mediated enhancement of carbon nanotube textiles by laser irradiation: Nanoparticle sweating and bundle alignment

The photonic post-processing of suspended carbon nanotube (CNT) ribbons made by floating catalyst chemical vapor deposition (FC-CVD) results in selective sorting of the carbon nanotubes present. Defective, thermally non-conductive or unconnected CNTs are burned away, in some cases leaving behind a highly crystalline (as indicated by the Raman G:D ratio), highly conductive network. However, the improvement in crystallinity does not always occur but is dependent on sample composition. Here, we report on fundamental features, which are observed for all samples. Pulse irradiation (not only by laser but also white light camera flashes, as well as thermal processes such as Joule heating) lead to (1) the sweating-out of catalyst nanoparticles resulting in molten catalyst beads of up to several hundreds of nanometres in diameter on the textile surface and (2) a significant improvement in CNT bundle alignment. The behavior of the catalyst beads is material dependent. Here, we show the underlying mechanisms of the photonic post-treatment by modelling the macro- and microstructural changes of the CNT network and show that it is mainly the amount of residual catalyst which determines how much energy these materials can withstand before their complete decomposition

Covid reallocation of spending : the effect of remote working on the retail and hospitality sector

A defining economic outcome from the Covid-19 pandemic is the unprecedented shift towards remote working from home. The extent and duration of this shift will have important consequences for local economies and especially the retail and hospitality sectors which depend on business around the workplace. Using a new bespoke, nationally representative survey of UK working age adults we analyse their ability and willingness to work remotely, and the consequences for spending on food, beverages, retail and entertainment around the workplace. We establish five key facts. (i) The post-pandemic change will be large: the fraction of work done from home will increase by 20 percentage points over its pre-pandemic level. (ii) The Dingel-Neiman (2020) assessment of remote working potential by occupation are reasonably predictive of what workers and employers expect to do, with a correlation coefficient of over 0.7. (iii) Relocation will be higher for better paid professional occupations, which will skew spending toward the most socio-economically affluent geographical areas. (iv) The corresponding geographical shift in annual retail and hospitality spending will be £3.0 billion with more remote working shifting demand away from urban areas. (v) On average, a 1% change in neighbourhood workforce changes local spending by 0.25%

Children and young people's body mass index measures derived from routine data sources: A national data linkage study in Wales.

BACKGROUND: Routine monitoring of Body Mass Index (BMI) in general practice, and via national surveillance programmes, is essential for the identification, prevention, and management of unhealthy childhood weight. We examined and compared the presence and representativeness of children and young people's (CYPs) BMI recorded in two routinely collected administrative datasets: general practice electronic health records (GP-BMI) and the Child Measurement Programme for Wales (CMP-BMI), which measures height and weight in 4-5-year-old school children. We also assessed the feasibility of combining GP-BMI and CMP-BMI data for longitudinal analyses. METHODS: We accessed de-identified population-level GP-BMI data for calendar years 2011 to 2019 for 246,817 CYP, and CMP-BMI measures for 222,772 CYP, held within the Secure Anonymised Information Linkage Databank. We examined the proportion of CYP in Wales with at least one GP-BMI record, its distribution by child socio-demographic characteristics, and trends over time. We compared GP-BMI and CMP-BMI distributions. We quantified the proportion of children with a CMP-BMI measure and a follow-up GP-BMI recorded at an older age and explored the representativeness of these measures. RESULTS: We identified a GP-BMI record in 246,817 (41%) CYP, present in a higher proportion of females (54.2%), infants (20.7%) and adolescents. There was no difference in the deprivation profile of those with a GP-BMI measurement. 31,521 CYP with a CMP-BMI had at least one follow-up GP-BMI; those with a CMP-BMI considered underweight or very overweight were 87% and 70% more likely to have at least one follow-up GP-BMI record respectively compared to those with a healthy weight, as were males and CYP living in the most deprived areas of Wales. CONCLUSIONS: Records of childhood weight status extracted from general practice are not representative of the population and are biased with respect to weight status. Linkage of information from the national programme to GP records has the potential to enhance discussions around healthy weight at the point of care but does not provide a representative estimate of population level weight trajectories, essential to provide insights into factors determining a healthy weight gain across the early life course. A second CMP measurement is required in Wales

Bringing the Street Back In:Considering Strategy, Contingency and Relative Good Fortune in Street Children’s Access to Paid Work in Accra

A sociology of street children has emerged defined by its rejection of the dominant narratives of child welfare organisations that identify the street as the root cause of children’s immiseration and improper socialisation. In its place, sociological analysis has undermined the value of conceptualising street children as a coherent group on the street and in a parallel move has looked to conceptually reposition street children away from assumptions of passivity and neglect, towards a foundational insistence that the starting place for analysis is the positioning of street children as active and strategic social agents. It is the adequacy of this latter concern that is the focus of this article. By reintroducing the location of children within the social relations of the informal street economy, this article draws upon extensive and long-term qualitative research examining the lives of street children in Accra, Ghana. The argument here is that sociological notions of strategic action and efficacious agency seem ill-suited to accounting for the dilemmas and difficulties that street children’s quests for paid work inevitably involve. Rather, it is relative good fortune within the radical uncertainty of the social relations of the informal street economy that seems much more appropriate to accounting for how these children are integrated into wor
