When Punishment Is Emotion-Driven: Children’S, Adolescents’, And Adults’ Costly Punishment Of Unfair Allocations, M Gummerum, B Lopez-Perez, E Van Dijk, Lf Van Dillen Jun 2019

When Punishment Is Emotion-Driven: Children’S, Adolescents’, And Adults’ Costly Punishment Of Unfair Allocations, M Gummerum, B Lopez-Perez, E Van Dijk, Lf Van Dillen

School of Psychology

When do children, adolescents, and adults decide to punish fairness violations? Two studies with 9-year-old children, 13-year-old adolescents, and adults investigated whether the link between unfairness and punishment was mediated by negative emotional reactions (measured through galvanic skin responses and emotion ratings). Study 1 (N = 117) examined this question in the context of second-party punishment, where the punisher is a direct victim of the violation. Study 2 (N = 119) assessed third-party punishment, where the punisher is an observer, unaffected by the violation. In each study, participants were presented with seven distributions of points, which differed in how fairly …


Reverse Engineering Field-Derived Vertical Distribution Profiles To Infer Larval Swimming Behaviors, M. K. James, J. A. Polton, A. R. Brereton, K. L. Howell, W. A.M. Nimmo-Smith, A. M. Knights Jun 2019

Reverse Engineering Field-Derived Vertical Distribution Profiles To Infer Larval Swimming Behaviors, M. K. James, J. A. Polton, A. R. Brereton, K. L. Howell, W. A.M. Nimmo-Smith, A. M. Knights

School of Biological and Marine Sciences

Biophysical models are well-used tools for predicting the dispersal of marine larvae. Larval behavior has been shown to influence dispersal, but how to incorporate behavior effectively within dispersal models remains a challenge. Mechanisms of behavior are often derived from laboratory-based studies and therefore, may not reflect behavior in situ. Here, using state-of-the-art models, we explore the movements that larvae must undertake to achieve the vertical distribution patterns observed in nature. Results suggest that behaviors are not consistent with those described under the tidally synchronized vertical migration (TVM) hypothesis. Instead, we show (i) a need for swimming speed and direction to …

Mitochondrial Activity And Skeletal Muscle Insulin Resistance In Kidney Disease, Jane E. Carré, C Affourtit Jun 2019

Mitochondrial Activity And Skeletal Muscle Insulin Resistance In Kidney Disease, Jane E. Carré, C Affourtit

School of Biomedical Sciences

Insulin resistance is a key feature of the metabolic syndrome, a cluster of medical disorders that together increase the chance of developing type 2 diabetes and cardiovascular disease. In turn, type 2 diabetes may cause complications such as diabetic kidney disease (DKD). Obesity is a major risk factor for developing systemic insulin resistance, and skeletal muscle is the first tissue in susceptible individuals to lose its insulin responsiveness. Interestingly, lean individuals are not immune to insulin resistance either. Non-obese, non-diabetic subjects with chronic kidney disease (CKD), for example, exhibit insulin resistance at the very onset of CKD, even before clinical …

A Disclosure Gel For Visual Detection Of Livebacillus Anthracisspores, Cv Robinson, Ah Bishop

School of Biological and Marine Sciences

Aims To develop a gel formulation to trigger a visual signal for rapid disclosure of the location and extent of surface contamination with viable Bacillus anthracis spores. Methods and Results Methylumbelliferyl-a-D-glucopyranoside was combined with hyaluronic acid to produce a gel that could be applied to a surface as a coating. It remained hydrated for a sufficient time for a-glucosidase activity present in intact B. anthracis spores to cleave the substrate and release the fluorescent product, methylumbelliferone. The presence of B. anthracis spores could be disclosed at 5 × 104 CFU per reaction test well (0·32 cm2) both visually and using …


Role Of Recent Climate Change On Carbon Sequestration In Peatland Systems., Paul H. Lunt, Ralph M. Fyfe, Alan D. Tappin Jun 2019

Role Of Recent Climate Change On Carbon Sequestration In Peatland Systems., Paul H. Lunt, Ralph M. Fyfe, Alan D. Tappin

School of Geography, Earth and Environmental Sciences

This paper provides information on the impact of recent climate change on carbon sequestration in peatland systems in South West England. This is important because peatlands have the potential to sequester and hold large quantities of anthropogenically released CO2. This paper investigates whether there has been a reduction in the strength of carbon sinks in a valley mire and blanket bog, which occur on the limits of the biogeographical envelop for peatlands in Britain. Past rates of carbon accumulation were calculated from peat depth and the sequential analysis of peat age, bulk density and carbon content from cores taken from …

The Oral Nitrate-Reducing Capacity Correlates With Peak Power Output And Peak Oxygen Uptake In Healthy Humans., B. Thomas, S. Smallwood, C. Clarke, R. Bescos Jun 2019

The Oral Nitrate-Reducing Capacity Correlates With Peak Power Output And Peak Oxygen Uptake In Healthy Humans., B. Thomas, S. Smallwood, C. Clarke, R. Bescos

School of Health Professions

Interest in inorganic nitrate and nitrite has grown substantially over the past decade as research has revealed the role of these anions in enhancing nitric oxide (NO) availability through an oral pathway. Nitrite synthesis in the mouth seems to be an important mechanism to feed the circulatory system with this anion. This is interesting since greater plasma nitrite concentration has been associated with better fitness levels in humans, but this question has not been investigated in relation to salivary nitrite concentration. Additionally, no previous study has investigated the oral nitrate-reducing capacity in regards to peak oxygen uptake (VO2peak) or peak …

Oral Bovine Colostrum Supplementation Does Not Increase Circulating Insulin-Like Growth Factor-1 Concentration In Healthy Adults: Results From Short- And Long-Term Administration Studies, G Davison, Aw Jones, T Marchbank, Rj Playford May 2019

Oral Bovine Colostrum Supplementation Does Not Increase Circulating Insulin-Like Growth Factor-1 Concentration In Healthy Adults: Results From Short- And Long-Term Administration Studies, G Davison, Aw Jones, T Marchbank, Rj Playford

Peninsula Medical School

PURPOSE: Bovine colostrum is available in health food shops and as a sports food supplement and is rich in antibodies and growth factors including IGF-1. World Anti-Doping Agency advises athletes against taking colostrum for fear of causing increased plasma IGF-1. There are also concerns that colostrum may theoretically stimulate malignancy in organs which express IGF-1 receptors. We, therefore, determined changes in plasma IGF-1 levels in subjects taking colostrum or placebo for 1 day, 4 weeks, and 12 weeks. METHODS: Plasma IGF1 levels were determined in healthy males (n = 16) who ingested 40 g bovine colostrum or placebo along with …

Chronosequence Of Former Kaolinite Open Cast Mines Suggests Active Intervention Is Required For The Restoration Of Atlantic Heathland, Mary Lane, Mick E. Hanley, Paul Lunt, Mairi E. Knight, Charlotte B. Braungardt, Jonathan S. Ellis May 2019

Chronosequence Of Former Kaolinite Open Cast Mines Suggests Active Intervention Is Required For The Restoration Of Atlantic Heathland, Mary Lane, Mick E. Hanley, Paul Lunt, Mairi E. Knight, Charlotte B. Braungardt, Jonathan S. Ellis

School of Biological and Marine Sciences

Atlantic lowland heath (ALH) is a priority conservation habitat in Western Europe, but restoration efforts have met with mixed success due to the complexity associated with replicating establishment conditions. By virtue of their impoverished, often acidic soils and geographic location in areas naturally occupied by ALH communities, former kaolinite mine sites may offer an excellent opportunity for heathland restoration. Using a chronosequence of former open cast kaolinite mines in South West England (0, 2, 27, and 150 years since mining ceased), we determined the ability of ALH vegetation and soils to reestablish naturally and in addition, for the three youngest …

School of Biological and Marine Sciences

All three species of angel sharks (genus Squatina) inhabiting the Mediterranean Sea are listed as Critically Endangered in the International Union for Conservation of Nature Red List of Threatened Species due to overexploitation. New records from Cyprus, Greece, Italy and Libya were collected from citizen-scientists and integrated with local knowledge obtained using structured interviews in the four countries. Observations and reports, together with an analysis of the reconstructed fisheries data, resulted in the identification of areas of interest, a review of the illegal trade of the species and a debate about the credibility of fisheries data for assessing threatened and/or …

Measurements of alkylamines from seawater and atmospheric samples collected simultaneously across the Antarctic Peninsula, South Orkney and South Georgia Islands are reported. Concentrations of mono-, di- and trimethylamine (MMA, DMA and TMA, respectively), and their precursors, the quarternary amines glycine betaine and choline, were enhanced in sympagic sea water samples relative to ice-devoid pelagic ones, suggesting the microbiota of sea ice and sea ice-influenced ocean is a major source of these compounds. Primary sea-spray aerosol particles artificially generated by bubbling seawater samples were investigated by Aerosol Time-Of-Flight Mass Spectrometry (ATOFMS) of single particles; their mixing state indicated that alkylamines were …

Storm Waves At The Shoreline: When And Where Are Infragravity Waves Important?, Oliver Billson, Paul Russell, Mark Davidson May 2019

Storm Waves At The Shoreline: When And Where Are Infragravity Waves Important?, Oliver Billson, Paul Russell, Mark Davidson

School of Biological and Marine Sciences

Infragravity waves (frequency, f = 0.005–0.05 Hz) are known to dominate hydrodynamic and sediment transport processes close to the shoreline on low-sloping sandy beaches, especially when incident waves are large. However, in storm wave conditions, how their importance varies on different beach types, and with different mixes of swell and wind-waves is largely unknown. Here, a new dataset, comprising shoreline video observations from five contrasting sites (one low-sloping sandy beach, two steep gravel beaches, and two compound/mixed sand and gravel beaches), under storm wave conditions (deep water wave height, H0 up to 6.6 m, and peak period, Tp up to …

Identification, Origin And Characteristics Of Bio-Bead Microplastics From Beaches In Western Europe., Andrew Turner, Claire Wallerstein, Rob Arnold May 2019

Identification, Origin And Characteristics Of Bio-Bead Microplastics From Beaches In Western Europe., Andrew Turner, Claire Wallerstein, Rob Arnold

School of Geography, Earth and Environmental Sciences

Primary microplastics have been collected from 17 beaches along the Atlantic, English Channel and southern North Sea coasts of western Europe. Based on visual characteristics, these plastics were differentiated as either relatively smooth, lentil- or disc-shaped pre-production pellets (or nurdles), which were usually a few mm in diameter and were mainly white to off-white, or rougher and more irregular pellets that were slightly larger and usually black. The latter appeared to be bio-beads, or plastics that are specifically manufactured for use as biomedia in certain sewage water treatment (SWT) plants and, possibly, in other industrial wastewater treatment applications. Identification of …
