Surveys of experiences of sexual violence and harassment in higher education: reports and findings

In April 2021, the Minister for Further and Higher Education, Research, Innovation and Science, Simon Harris, asked the Higher Education Authority (HEA) to conduct national surveys to track students\u27 and staff\u27s experiences of sexual violence and harassment. Working with an expert advisory group, the HEA Centre of Excellence for Equality Diversity and Inclusion ran surveys of staff and students in April 2021. 7,901 students and 3,516 staff answered the surveys (11,417 responses in total). The department will use the results of these surveys to make policy and funding decisions to tackle sexual violence and harassment in higher education institutions (HEIs)

Assessment of health in human faces is context-dependent

This work was supported by the National Environment Research Council, UK (KM), Unilever Research & Development USA and the Economic and Social Research Council (RW, DP).When making decisions between options, humans are expected to choose the option that returns the highest benefit. In practice, however, adding inferior alternatives to the choice set can alter these decisions. Here we investigated whether decisions over the facial features that people find healthy looking can also be affected by the context in which they see those faces. To do this we examined the effect of choice set on the perception of health of images of faces of light-skinned Caucasian females. We manipulated apparent facial health by changing yellowness of the skin: the healthy faces were moderately yellow and the less healthy faces were either much more yellow or much less yellow. In each experiment, two healthy faces were presented along with a third, less healthy face. When the third face was much more yellow, participants chose the more yellow of the two healthy faces more often as the most healthy. However, when the third face was the least yellow, participants chose the less yellow of the two healthy faces more often. A further experiment confirmed that this result is not due to a generalised preference for an intermediate option. These results extend our understanding of context-dependent decision-making in humans, and suggest that comparative evaluation may be a common feature across many different kinds of choices that humans have to make.PostprintPeer reviewe

Image analysis of weaverbird nests reveals signature weave textures

This work was supported by the BBSRC (BB/I019502/1, S.D.H. and S.L.M.), the Roslin Institute Strategic Grant funding from the BBSRC (S.L.M) and the Leverhulme Trust (S.D.H. and P.T.W.), and A.R.B. gratefully acknowledges the financial support of CNPq (National Council for Scientific and Technological Development, Brazil, grant no. 301558/2012-4).In nature, many animals build structures that can be readily measured at the scale of their gross morphology (e.g. length, volume and weight). Capturing individuality as can be done with the structures designed and built by human architects or artists, however, is more challenging. Here, we tested whether computer-aided image texture classification approaches can be used to describe textural variation in the nests of weaverbirds (Ploceus species) in order to attribute nests to the individual weaverbird that built them. We found that a computer-aided texture analysis approach does allow the assignment of a signature to weaverbirds’ nests. We suggest that this approach will be a useful tool with which to examine individual variation across a range of animal constructions, not just for nests.Publisher PDFPeer reviewe

Experimental and modeled thermoregulatory costs of repeated sublethal oil exposure in the Double-crested Cormorant, \u3ci\u3ePhalacrocorax auritus\u3c/i\u3e

To fully understand the impact of oil exposure, it is important to understand sublethal effects like how increased thermoregulatory costs may affect survival and reproduction. However, it is difficult and time-consuming to measure these effects in wild animals. We present a novel use of a bioenergetics model, Niche Mapper™, to estimate thermoregulatory impacts of oiling, using data from captive Double-crested Cormorants (Phalacrocorax auritus) experimentally exposed to oil. Oiled cormorants had significant increases in surface body temperatures following exposure. Niche Mapper accurately predicted surface temperatures and metabolic rates for unoiled and oiled cormorants and predicted 13–18% increased daily energetic demands due to increased thermoregulatory costs of oiling, consistent with increased food consumption observed in experimentally oiled cormorants. We show that Niche Mapper can provide valuable insight into sublethal oiling effects by quantifying the extent to which thermoregulatory costs divert energy resources away from important life processes like maintenance, reproduction and migration

Nitrate-Stimulated Release of Naturally Occurring Sedimentary Uranium

Groundwater uranium (U) concentrations have been measured above the U.S. EPA maximum contaminant level (30 μg/L) in many U.S. aquifers, including in areas not associated with anthropogenic contamination by milling or mining. In addition to carbonate, nitrate has been correlated to uranium groundwater concentrations in two major U.S. aquifers. However, to date, direct evidence that nitrate mobilizes naturally occurring U from aquifer sediments has not been presented. Here, we demonstrate that the influx of high-nitrate porewater through High Plains alluvial aquifer silt sediments bearing naturally occurring U(IV) can stimulate a nitrate-reducing microbial community capable of catalyzing the oxidation and mobilization of U into the porewater. Microbial reduction of nitrate yielded nitrite, a reactive intermediate, which was further demonstrated to abiotically mobilize U from the reduced alluvial aquifer sediments. These results indicate that microbial activity, specifically nitrate reduction to nitrite, is one mechanism driving U mobilization from aquife

Barriers to managing childhood mental health problems: a systematic review of primary care practitioner's perceptions

Background: Mental health problems are common and typically have an early onset. Effective treatments for mental health problems in childhood and adolescence are available yet only a minority of affected children access them. This is of serious concern, considering the far-reaching and long-term negative consequences of such problems. Primary care is usually the first port of call for concerned parents so it is important to understand how primary care practitioners (PCPs) manage childhood mental health problems and the barriers they face. Aim: To ascertain PCP’s perceptions of barriers preventing effective management of childhood mental health problems Design: A systematic review of qualitative and quantitative literature Method: A database search of peer-reviewed articles using PsycInfo, MEDLINE, EMBASE and Web of Science, until October 2014, was conducted. Additional studies were identified through hand-searching and forward-citation searches. Studies needed to have at least one search term in four categories: (i) primary care, (ii) childhood/adolescence, (iii) mental health and (iv) barriers. Results: A total of 4151 articles were found, of which 43 were included (30 quantitative and 13 qualitative). The majority of the barriers related to identification, management and/or referral. Considerable barriers included a lack of providers and resources, extensive waiting lists and financial restrictions. Conclusion: The identification of a broad range of significant barriers highlights the need to strengthen the ability to deal with these common difficulties in primary care. There is a particular need for tools and training to aid accurate identification and management, and for more efficient access to specialist services
