Bending and flexural-buckling strength of steel members considering strain-rate-effects at elevated temperatures
Authors: Ozaki Fuminobu , Umemura Takumi 
Published: December 2021

PurposeIn this study, the bending strength, flexural buckling strength and collapse temperature of small steel specimens with rectangular cross-sections were examined by steady and transient state tests with various heating and deformation rates.Design/methodology/approachThe engineering stress and strain relationships for Japan industrial standard (JIS) SN400 B mild steels at elevated temperatures were obtained by coupon tests under three strain rates. A bending test using a simple supported small beam specimen was conducted to examine the effects of the deformation rates on the centre deflection under steady-state conditions and the heating rates under transient state conditions. Flexural buckling tests using the same cross-section specimen as that used in the bending test were conducted under steady-state and transient-state conditions.FindingsIt was clarified that the bending strength and collapse temperature are evaluated by the full plastic moment using the effective strength when the strain is equal to 0.01 or 0.02 under fast strain rates (0.03 and 0.07 min–1). In contrast, the flexural buckling strength and collapse temperature are approximately evaluated by the buckling strength using the 0.002 offset yield strength under a slow strain rate (0.003 min–1).Originality/valueRegarding both bending and flexural buckling strengths and collapse temperatures of steel members subjected to fire, the relationships among effects of steel strain rate for coupon test results, heating and deformation rates for the heated steel members were minutely investigated by the steady and transient-state tests at elevated temperatures.
Impact of the COVID-19 pandemic on the well-being of the stranded seafarers
Authors: Wong Chun Pong 
Published: December 2021

PurposeThis study examines the impact of the COVID-19 pandemic on the well-being and mental health of the seafarers who had to overstay on ships after their contracts expired, identifies topics that affect their mental distress and recommends measures to overcome these.Design/methodology/approachFour research questions about the impacts on the seafarers before and during the COVID-19 pandemic were raised. A literature review and a questionnaire survey were conducted to find answers. Ship officers were asked to assess and fill in the questionnaires for the stranded seafarers onboard in order to collect sufficient samples rapidly for this study.FindingsDespite the guidelines provided by the shipping companies being adequate to protect the seafarers from COVID-19, their mental distress levels have been worsened under the pandemic. The crew change crisis causes anxiety and negatively impacts on their working performance; however, the repatriation expectation of the stranded seafarers is of the highest concern. Three topics were identified as having impacts on the mental health of the stranded seafarers: crew change crisis, low vaccination rate and the lack of key worker recognition. While international stakeholders are advocating for support in these issues, the shipping companies and the seafarers need to do their parts to exacerbate the mental distress, and to survive and thrive beyond the pandemic.Originality/valueThe findings of this study will help the shipping companies to navigate the challenges and the seafarers to overcome issues caused by the COVID-19 pandemic.
Health and social care access for adults with learning disabilities across the UK during the COVID-19 pandemic in 2020
Authors: Flynn Samantha , Hatton Chris 
Published: December 2021

Purpose
This paper aims to present data about access to health and social care services during the COVID-19 pandemic for adults with learning disabilities across England, Northern Ireland, Scotland and Wales.

Design/methodology/approach
Data were collected directly from 621 adults with learning disabilities and through separate proxy reports by family carers and paid support staff of another 378 adults with learning disabilities. The data were collected between December 2020 and February 2021 and concerned the use of health and social care services since the start of the first COVID-19 national lockdown in March 2020.

Findings
Access to and use of health and social care services significantly reduced for adults with learning disabilities across the UK during the COVID-19 pandemic between March 2020 and February 2021, with many people not receiving any services at all during that period. Similar patterns were seen across England, Northern Ireland, Scotland and Wales. However, data suggest some variations between countries for some services.

Practical implications
Future pandemic planning must ensure that access to these essential services is not completely lost for adults with learning disabilities and their family carers, as it was in some cases during the COVID-19 pandemic in 2020.

Originality/value
This is the largest study about the impact of the COVID-19 pandemic on health and social care services for adults with learning disabilities in the UK. The authors primarily collected data directly from adults with learning disabilities, and worked with partner organisations of people with learning disabilities throughout the study.
William Gladstone and the Homeric Constitution
Authors: PAYNTER ALASTAIR 
Published: December 2021

AbstractBetween 1858 and 1890 the British statesman William Ewart Gladstone produced five major works on the Greek poet Homer, in addition to a number of smaller articles and pamphlets on related subjects. Although these studies examined all aspects of the Homeric world in the minutest detail, the most enduring analysis concerned the politics of the poems. He considered Homer to stand at the fountainhead of the Western political tradition and therefore to be of the utmost importance for students of politics. Examining the tripartite division of the Homeric constitution between king, council and assembly, he went so far as to discern the distant ‘germ’ of the English constitution. Despite minor modulations, his political reading of Homer remained remarkably constant throughout his life, despite his own party‐political evolution from Tory to Peelite to Liberal. This article considers his reading of the Homeric polity and suggests that this continuity of analysis reflects a far greater and deeper constancy and stability in his own thought than many scholars have allowed for.
Assessing transport and retention of nitrate and other materials through the riparian zone and stream channel with simulated precipitation

Abstract

Riparian zones, the interfaces between land and stream, perform vital ecosystem functions including transformation and retention of nutrients and sediment moving across the landscape. Although many studies assess transport through and transformation of materials in riparian zones, less is known about the direct influence of precipitation falling on these zones on material retention and transport. Additionally, few experiments can compare riparian retention to stream‐channel retention.

We present a novel experimental approach to assess retention of nitrate entering as precipitation in riparian zones and compare riparian retention and movement of nitrate, other ions, sediments to and within the adjacent stream channel. We simulated an intense precipitation event with 15N‐labelled nitrate as a bioactive solute and bromide as an inert tracer. This method extends tracer release approaches applied to streams worldwide and links it to processes at the aquatic/ terrestrial interface. It further allows determination of movement of materials into streams from bankside precipitation.

The riparian zone removed or retained a greater proportion of nitrate than the stream relative to bromide; over half the added bromide reached the stream through a few metres of riparian zone, compared to only 0.2% of the added nitrate. Of the 0.2% that reached the stream, 30% of that nitrate was removed or retained by instream processes after travelling 60 downstream. Roughly 10% of the total 15N addition ended up sequestered in the above‐ground portions of the riparian grasses by the end of the growing season, and very little of it was recovered from the soil. We saw little evidence of bulk transport of other ions or sediment from this riparian soil to the stream.

Our data are consistent with the concept of high nitrate retention in vegetated riparian zones, even for nitrate falling directly upon them in the form of atmospheric deposition in precipitation.

AbstractBackgroundNormothermic machine perfusion provides continuous perfusion to ex situ hepatic grafts through the portal vein and the hepatic artery. Because the portal vein has high flow with low pressure and the hepatic artery has low flow with high pressure, different types of perfusion machines have been employed to match the two vessels’ infusion hemodynamics.MethodsWe compared transplanted human livers perfused through a 2‐pump (n = 9) versus a 1‐pump perfusion system (n = 6) where a C‐clamp is used as a tubing constrictor to regulate hemodynamics.ResultsThere was no significant difference between groups in portal vein or hepatic artery flow rate. The 1‐pump group had more hemoglobin in the perfusate. However, there was no significant difference in plasma hemoglobin between the 2‐pump and 1‐pump groups at each time point or in the change in levels, proving no hemolysis occurred due to C‐clamp tube constriction. After transplantation, the 2‐pump group had two cases of early allograft dysfunction (EAD), whereas the 1‐pump group had no EAD. There was no graft failure or patient death in either group during follow‐up ranging from 20–52 months.ConclusionsOur data show that the 1‐pump design provided the same hemodynamic output as the 2‐pump design, with no additional hemolytic risk, but with the benefits of lower costs, easier transport and faster and simpler setting.
Securing collective representation in non‐union European multinational companies: The case of Ryanair pilots’ (partial) success
Authors: Geary John F. 
Published: December 2021

AbstractCompelling a recalcitrant employer to cede its staff independent collective representation has always been a fraught and difficult exercise. It is an inordinately more complex task when that employer is a multinational company that is capable of moving its operations from one country to another with relative ease. For workers to be successful, requires that they and their representatives coordinate their organizing and mobilizing activities across national boundaries in a manner that they have rarely been able to achieve. This inductive study examines one such rare example – Ryanair – and investigates the basis for its pilots’, albeit partial, success. Its contribution is the explication of a causal model that identifies a set of institutional and structural conditions, and agentic actions that led Ryanair to cede its staff union representation, while also pointing to the limitations of the pilots’ ‘victory’. It ends by identifying a number of changes to Europe's institutional and regulatory architecture that, if enacted, could help the workers of resolutely anti‐union MNEs secure recognition for unitary pan‐European structures of representation.

Published: December 2021

AbstractThe Permian‐Triassic alluvial rift succession in the Horda Platform area is analysed to construct a refined depositional model. The study demonstrates how subsurface continental rift successions may be stratigraphically subdivided and correlated by integrating seismic and well‐log data in concert with conceptual models. Regional unconformities mark the top and base of the Permian‐Triassic succession, which is sub‐divided into six seismic stratigraphic sequences, delineated by erosional‐ and non‐depositional surfaces. The definition of seismic stratigraphic sequences is based on seismic facies trends and Gamma Ray log signatures. Time‐thickness maps combined with geometries in cross‐section display the depocentre development. During the Permian‐Triassic, the Horda Platform experienced faulting, shaping the Caledonian pre‐rift landscape into a series of N–S trending half‐graben basins, contemporaneous to a gradual climate change from arid in the Permian to humid in the latest Triassic. The basin underwent three phases of rifting during the Late Permian‐Middle Triassic: (1) disconnected heterogeneous depocentres with strain concentrated in the west; (2) depocentres expanded northward; and (3) mature half graben development with widely distributed strain. Vertical lithological changes in mudstone/sandstone dominance reflect varying rates of accommodation and sediment supply (A/S). Systematic A/S variation reflects strong climatic fluctuations, which controlled facies patterns during both tectonic quiescence in the Middle‐Late Triassic, and during syn‐rift sedimentation. The Permian‐Triassic tectono‐sedimentary development in the Horda Platform area provides valuable lessons on the influence of faulting on depocentre development, how the interplay between tectonic and climatic forcing is expressed in subsurface continental deposits, and aid the characterisation of reservoirs.
Young people's engagement with climate change issues through digital media – a content analysis
Authors: Parry Sarah , McCarthy Sofi Rose , Clark Jennie 
Published: December 2021

BackgroundThe reporting of climate change issues through social media can influence young people’s mental health and engagement. However, there has been little research undertaken directly with young people in relation to social and digital media’s reporting of climate change, and how this is experienced by young people.MethodThis study aimed to explore the interface between climate change and social media reporting for young people. A two‐stage iterative approach to recruitment and data collection included an initial qualitative stage (N = 28), consisting of open‐ended questions about social media’s reporting of climate change issues. The second stage (N = 23) included further open‐ended questions and 10 Likert‐Scale questions. Overall, 51 young people 16–25‐years‐old opted to take part (M = 11; F = 40). Descriptive statistics and an inductive data‐driven content analysis are reported.ResultsOverall, 95% of the participants reported that they had the personal skills to cope with climate change reporting on social media. Most participants stated that coverage on the climate increased ‘climate change anxiety’ but not their overall mental health difficulties. A four‐stage experiential process of observing social media’s reporting of climate change, feeling emotionally affected by the reporting, critically apprising the content and feeling motivated to engage in climate change activism emerged from the content analysis. The participants discussed experiences of digital media, rather than solely social media, in their accounts.ConclusionsThe participants recommended changes to climate change reporting and increasing access to education about climate change issues to reduce anxiety and enhance motivation for positive personal engagement. Involving young people in conversations and education about climate change were seen as protective factors for mental health and enablers for motivation. Motivation, agency and pathways for positive change were associated with hopefulness.
Skills of the future for a high‐performing workforce: Implications of recent evidence for the public sector
Authors: Delisle Marc , Lajoie Denis 
Published: December 2021

AbstractAdvances in technology spur speculation as to the challenges inherent to the future of work and the skills and abilities that will be necessary to meet these challenges. We challenge this speculation by reviewing scientific evidence regarding 20 so‐called skills and abilities of the future that are identified in five influential reports in the popular literature (i.e., research‐oriented but non‐academic publications intended for government or business audiences), while focusing on empirical evidence of relationships with performance on the job. We find that many of the skills identified in the popular literature surveyed have not been empirically tested, that when they were tested the quality of data is often very limited, and that there is much conceptual confusion regarding skills and abilities in the popular literature. Now, and for the foreseeable future, general mental ability appears to be the best validated factor upon which performance can be built.
Supportive relations in a feminized occupation: How male and female veterinarians compare
Authors: Wallace Jean E. , Kay Fiona M. 
Published: December 2021

AbstractSeveral traditionally male‐dominated professions, including law and medicine, have experienced an influx of women over the last 30 years. We extend research on gender equality in the professions, which has often examined segmentation and stratification, by examining the integration of men and women into a traditionally male‐dominated profession in terms of the emotional and instrumental support they receive from colleagues. We examine veterinary medicine as a case study because interestingly this profession has seen the most dramatic growth in the representation of women over the last 30 years – more than law or medicine. We also explore whether traditional masculine control tasks (clinic ownership and autonomy) and traditional female care tasks (animal care and client interactions) are related to integration. We analyze survey data from 384 Canadian veterinarians. Findings show that practice ownership and challenging client interactions are associated with reduced support for women, but not for men. In contrast, directly caring for animals is associated with more support for men, but this is not the case for women. We discuss the implications of differential levels of social support for the integration of women into traditionally male‐dominated professions.

Abstract
Paradoxical psoriatic arthritis (PPsA) may be associated with guselkumab treatment. We describe a patient in whom PPsA required a change from guselkumab to ixekizumab. The pathophysiology of this paradoxical reaction is most likely a cytokine imbalance.
Support to Iberian lynx reintroduction and perceived impacts: Assessments before and after reintroduction

AbstractThe assessment of the human dimensions of wildlife reintroduction projects is essential for their success. To date, few longitudinal studies (if any) have compared attitudes and perceived impacts before and after human‐assisted large predator reintroduction. In this study, we evaluated public (n = 1582) and hunters' (n = 773) support and perceived benefits and concerns before and after the reintroduction of the Iberian lynx (Lynx pardinus) (2007–2008 and 2015–2016, respectively) in southern Spain through a telephone survey. Most respondents supported lynx reintroduction, although support was slightly lower among hunters. Furthermore, support remained very high some years after lynx release. Our findings also revealed that perceptions toward the majority of benefits and concerns did not change after lynx reintroduction, and that those supporting reintroduction perceived more benefits, while opponents were more concerned. This suggests that efforts should focus on those opponents to reintroduction to ensure recognition of the benefits associated with predator restoration, including new tourism opportunists and predator's ecological values. Our research also points at the need of studying more in depth the views of those who oppose to predator reintroduction and of decision‐makers (e.g., landowners or game managers) when poaching is still a risk for restored populations even if the social context is favorable, as in our case‐study.
Discriminating Thieves: Exhibiting Nazi‐Era Provenance
Authors: Mallon MacKenzie 
Published: December 2021

AbstractIn‐house exhibitions focusing on the results of Nazi‐era provenance research are uncommon in American museums, but they can be an excellent opportunity for an institution to increase the transparency of their collection’s provenance, while simultaneously engaging visitors through the interesting stories behind the collection’s history. Discriminating Thieves: Nazi‐Looted Art and Restitution, exhibited at The Nelson‐Atkins Museum of Art in 2019–2020, utilized the results of archival provenance research to describe the histories of four objects from the Museum’s permanent collection that were appropriated during the Nazi era. The exhibition traced each object’s provenance from its prewar owner, through its confiscation, recovery and restitution, and ultimate acquisition by the Nelson‐Atkins.

Published: December 2021

AbstractThis case report outlines a rare complete intrusion of a permanent, maxillary central incisor (tooth 11) into the nasal cavity, with a late diagnosis and treatment. An eight‐year‐old boy was referred to an oral and maxillofacial surgery service with absence of tooth 11 after an episode of a fall from his own height. Approximately 50 days after the trauma, the patient presented with a complaint of obstruction of the right nostril. The clinical examination and tomographic evaluation showed that the tooth had been intruded into the nasal cavity on the right side. The tooth in question was removed under general anesthesia by direct approach through the right nostril. The patient was followed up for approximately one year without complications. This case demonstrates the importance of a detailed evaluation during the first examination after intrusive luxation, so the correct diagnosis is made and the correct treatment is performed to avoid greater morbidity and complications for the patient.
