Agronomic and genetic assessment of organic wheat performance in England: a field-scale cultivar evaluation with a network of farms
Authors: Costanzo Ambrogio , Amos Dominic , Bickler Charlotte , Trump Andrew 
Published: July 2021

AbstractYield gaps between organic and conventional agriculture raise concerns about future agricultural systems which should reduce external inputs and face an unpredictable climate. In the UK, the performance gap is especially severe for wheat that, as a result, has a small and shrinking organic acreage. In organic wheat production, most determinants of crop performance are managed at a rotation level, which leaves cultivar choice as the major decision on a seasonal basis. Yet, conventionally generated cultivar recommendations might be inappropriate to organic farms. Furthermore, uncertainty about field-scale crop performance hinders positive developments of the supply chain of organic grains and seeds. Here, we present a field-scale evaluation of winter wheat cultivars, integrated with an agronomic crop performance survey, across a network of organic farms. The relation between crop performance and climatic patterns is explored, to capitalise past growing seasons in cultivar and management decisions on-farm. Grain yield and grain protein content were linked by a dual relation, positive across environments and negative across cultivars. Feed-grade cultivars showed a relatively high yield (4.5–5.5 t/ha) but low protein (8.5–9.3%), whereas breadmaking and historic cultivars showed higher protein (10.4–11.1%) and lower yields (3.5–4.0 t/ha). Historic phenotypes showed better weed suppressive ability than modern ones, without trade-offs with yield or quality. Multiple regressions showed that weed abundance at wheat anthesis was the main yield predictor. The effects of two different post-emergence weed management strategies were observed. Farms relying on interrow hoeing showed lower weed abundance, but a higher relative abundance of the dominant species than that of those relying on spring tine harrowing. Future wheat breeding and cultivar testing should account for crop-weed relations, weed management strategies and their effects on nutrient use efficiency. Further data collection can inform plant breeding on critical traits for low-input farming and shed light on cultivar-environment-management interactions.
The Scapegoat Mechanism in Human Evolution: An Analysis of René Girard’s Hypothesis on the Process of Hominization
Authors: Riordan D. Vincent 
Published: July 2021

AbstractAccording to anthropological philosopher René Girard (1923–2015), an important human adaptation is our propensity to victimize or scapegoat. He argued that other traits upon which human sociality depends would have destabilized primate dominance-based social hierarchies, making conspecific conflict a limiting factor in hominin evolution. He surmised that a novel mechanism for inhibiting intragroup conflict must have emerged contemporaneously with our social traits, and speculated that this was the tendency to spontaneously unite around the victimization of single individuals. He described an unconscious tendency to both ascribe blame and to imbue the accused with a sacred mystique. This emotionally cathartic scapegoat mechanism, he claimed, enhanced social cohesion, and was the origin of religion, mythology, sacrifice, ritual, cultural institutions, and social norms. It would have functioned by modifying the beliefs and behaviors of the group, rather than of the accused, making the act of accusation more important than the substance. This article aims to examine the empirical evidence for Girard’s claims, and argues that the scapegoat hypothesis has commonalities with several other evolutionary hypotheses, including Wrangham’s execution hypothesis on self-domestication, Dunbar’s hypothesis on the role of storytelling in maintaining group stability, and DeScioli and Kurzban’s hypothesis on the role of non-consequentialist morality in curtailing conflict. Potential implications of the scapegoat hypothesis for evolutionary psychology and psychiatry are discussed.
Survivors of Hell: Resilience Amongst Unaccompanied Minor Refugees and Implications for Treatment- a Narrative Review
Authors: Rodriguez Irene Mateos , Dobler Veronika 
Published: July 2021

AbstractApproximately half of the world’s displaced population are children and a significant proportion of these are unaccompanied asylum-seeking children (UASC). UASC are the most vulnerable of all refugee populations. Up to 90% of UASC have been subjected to exploitation, including trafficking or being drafted into military groups. Having survived the perils of flight, UASC are confronted with continued challenges, including the uncertainties regarding their residential rights in host counties. Unsurprisingly, the prevalence of mental health problems is higher amongst UASC than in any other refugee group. Yet, Mental Health and Psychosocial Support (MHPSS) appears to neither reach nor engage UASC. This begs for re-examination of what and how MHPSS is offered. Despite high levels of adversity, UASC often have considerable resilience, and make remarkable recoveries. However, literature exploring their resources or their own views of what helps or hinders recovery is scarce. In this narrative review, we explore individual and systemic factors promoting recovery in UASC. We consider theoretical understanding of resilience, emerging data and user perspectives. From these we deduct four areas of resilience in UASC: Individual factors – prosocial behaviour, problem-solving skills; Lifetime relationships – positive early family relationships, connection with family and country of origin, positive peer and adult relationships in host country; Acculturation – integration of own and new culture, positive relationships with prosocial institutions; Care arrangements – supported but less restrictive living arrangements. We suggest, MHPSS may need to focus on enhancing social networks, including connectedness with positive relationships in the home-country, life-history work with a focus on resource-building experiences in addition to trauma, and promoting integration of old and new cultural values. We also conclude that despite growing data, there is a gap in both eliciting user perspectives and understanding adaptive resources, especially those emerging during early development and within their cultural setting.
‘Take the Money and Run’: Dutch Evidence on Inheritance and Transfer Receiving and Divorce
Authors: Basiglio Stefania 
Published: July 2021

AbstractThis paper aims to investigate whether a wealth endowment, such as an inheritance or a gift, can increase the chances of getting divorced, using Dutch panel data for the period from 2002 to 2016. According to the literature, different factors may lead to the breakdown of a marriage; however, the role played by inherited wealth has never been explored so far. Starting from the idea that the receipt of an inheritance might have an impact on various aspects of an individual’s life, estimations of a Cox proportional hazard ratios model are performed and tests are carried out to establish which variables, with particular attention being given to inherited wealth, act as drivers in increasing the chances of withdrawing from a marriage. The findings suggest that when the wealth endowment has been received by the wife, this increases the chances of the couple separating. This signals that receiving an inheritance/gift changes the bargaining power between the couple: for the husband, it does not represent an incentive to divorce, while the results suggest that the wife might perceive a change in the bargaining power, increasing the likelihood of marital disruption.

AbstractMAX phases are gaining attention as precursors of two-dimensional MXenes that are intensively pursued in applications for electrochemical energy storage. Here, we report the preparation of V2SnC MAX phase by the molten salt method. V2SnC is investigated as a lithium storage anode, showing a high gravimetric capacity of 490 mAh g−1 and volumetric capacity of 570 mAh cm−3 as well as superior rate performance of 95 mAh g−1 (110 mAh cm−3) at 50 C, surpassing the ever-reported performance of MAX phase anodes. Supported by operando X-ray diffraction and density functional theory, a charge storage mechanism with dual redox reaction is proposed with a Sn–Li (de)alloying reaction that occurs at the edge sites of V2SnC particles where Sn atoms are exposed to the electrolyte followed by a redox reaction that occurs at V2C layers with Li. This study offers promise of using MAX phases with M-site and A-site elements that are redox active as high-rate lithium storage materials.
Investigation of deviations in SI-engine behaviour due to manufacturing tolerances in cylinder heads

Published: July 2021

AbstractCast engine components are experiencing ever tighter tolerance requirements and at the same time a more complex cast design. The geometries, some of which are inaccessible, are tested for quality assurance on the basis of relevant component characteristics, among other things. The position check measures the actual position of a feature in a spatial dimension. Information about the alignment and geometry of the combustion chamber cannot be derived from the measurement methods applied. The use of three-dimensional measuring methods, e.g., imaging by computer tomography, can additionally record the spatial component position and the component geometry. Further measurement data can be derived from this, which serves to increase process reliability and component quality, and to increase component quality within an entire component batch. On the one hand, the cylinder head limits the working space by the roof of the combustion chamber, on the other hand, the cylinder head has a significant influence on the charge movement, especially at the beginning of the intake flow, due to the geometry of the intake ducts. On account the high demands of modern gasoline engines with tumble combustion process paired with Miller operation at partial load, variable timing, etc., mixture formation is important for efficient operation. Mixture formation in air- and wall-guided combustion processes depends on the components air duct and injection. From the point of view of cylinder head production, the mixture formation component air guiding is an elementary development approach for implementing efficient and sustainable component production while ensuring component properties. From this, the question can be derived as to what influence, for example, different dimensional tolerances in the combustion chamber size have on engine operation. To address this question, 3D simulations and physical test bench measurements were performed. With a variation of the above-mentioned intake duct and combustion chamber geometries and due to manufacturing tolerances, simulation results and measurement data were evaluated, analysed and presented in this paper. The influence of manufacturing-relevant tolerance deviations in the early process step of cylinder head production on combustion engine operation can be recognised in different ways.

Published: July 2021

ABSTRACTBackgroundPhysician prescribing patterns surrounding the use of testosterone therapy (TTh) in men with a history of prostate cancer (CaP) is not well described.AimTo characterize the demographics and usage patterns of testosterone therapy in men with a history of prostate cancer in the United States.MethodsThis was a retrospective review using Optum’s De-identified Clinformatics Data Mart database. Administrative diagnosis, procedural, pharmacy, and laboratory codes were used to identify male subjects 40 years and older with prostate cancer treated with surgery or radiation between 2003 and 2018 who went on to receive TTh. Demographic and clinical factors are identified. Temporal trends in TTh usage were reported.OutcomesThe main outcomes were rates of testosterone prescriptions in men with treated prostate cancer and associated laboratory values such as Prostate Specific Antigen (PSA) and testosterone levels before TTh.RESULTS126,374 men completed treatment for CaP during the study period (42,515 surgery, 75,186 radiation, 8,673 both). Of these, 3,074 men (2.4%) received testosterone after CaP treatment. Men who received testosterone were younger, more likely to have erectile dysfunction, depressive disorder, and lower pretreatment PSA values compared to men who did not receive. Median PSA levels before TTh initiation were 0 – 0.2 depending on CaP treatment modality and median total testosterone level was &lt;300 ng/dL. TTh began an average of 1.5 years after radical prostatectomy and 2.6 years after radiation treatment. We observed an increase in TTh after CaP from the beginning of the study period until it peaked in 2013 at 4.9%. After 2013, rates decreased annually until a plateau of approximately 1.8% of men. Approximately a third of men did not have testosterone labs checked before initiation of TTh.Clinical ImplicationsThese findings provide insight into trends in testosterone prescriptions in men after prostate cancer treatment and may aid in clinical decision-making, as well as areas for improvement in cancer survivorship care.Strengths and LimitationsStrengths include the large sample size, length of data coverage, and real-world analysis of testosterone prescribing patterns across the United States. Limitations include the reliance on insurance claims data, the retrospective study design, and lack of additional relevant clinical variables that may impact decision making regarding TTh.CONCLUSIONNational trends in testosterone prescriptions for men with treated prostate cancer suggest that many men are treated with TTh after prostate cancer therapy with patterns of indications and monitoring consistent with the general population.

Resistance Is Not Futile: Co-operatives, Demutualization, Agriculture, and Neoliberalism in Australia
Authors: Patmore Greg , Balnave Nikola , Marjanovic Olivera 
Published: July 2021

AbstractRecognition of co-operatives as a legitimate business model and form of economic participation was significantly challenged by the rise of neo-liberalism in the 1980s with its emphasis on individuals and markets. This fueled an externally and internally driven push to demutualize co-operatives and convert them into Investor Owned Businesses (IOB). While the international trend to demutualize emerged from the end of the Second World War, evidence indicates it accelerated from the late 1980s until the onset of the Global Financial Crisis. Drawing on an ongoing project of historical data collection and visual analysis of Australian co-operatives, this paper explores the Australian experience with demutualization, particularly with regard to agriculture. In line with the international experience, there has been a surge in Australian demutualization since the 1980s. However, while demutualization continues to be a feature of the Australian landscape post-GFC as co-operatives tackle with the changed political and economic environment, the paper also challenges the view that demutualization is inevitable for agricultural co-operatives. Co-operative managers can make strategic choices to avoid demutualization and retain member control. Further, co-operative culture and the persistence of co-operative clusters in particular regions can blunt the push to demutualize.
Neurological Determination of Death Following Infratentorial Stroke: A Population-Based Cohort Study
Authors: Kramer Andreas H. , Kromm Julie A. , Doig Christopher J. , Chassé Michaël , Couillard Philippe L. 
Published: July 2021

ABSTRACT:Background:There is international variability in whether neurological determination of death (NDD) is conceptually defined based on permanent loss of brainstem function or “whole brain death.” Canadian guidelines are not definitive. Patients with infratentorial stroke may meet clinical criteria for NDD despite persistent cerebral blood flow (CBF) and relative absence of supratentorial injury.Methods:We performed a multicenter cohort study involving patients that died from ischemic or hemorrhagic stroke in Alberta intensive care units from 2013 to 2019, focusing on those with infratentorial involvement. Medical records were reviewed to determine the incidence and proportion of patients that met clinical criteria for NDD; whether ancillary testing was performed; and if so, whether this demonstrated the absence of CBF.Results:There were 95 (27%) deaths from infratentorial and 263 (73%) from supratentorial stroke. Sixteen patients (17%) with infratentorial stroke had neurological examination consistent with NDD (0.55 cases per million per year). Among patients that underwent confirmatory evaluation for NDD with an apnea test, ancillary test (radionuclide scan), or both, ancillary testing was more common with infratentorial compared with supratentorial stroke (10/12 (85%) vs. 25/47 (53%), p = 0.04). Persistent CBF was detected in 6/10 (60%) patients with infratentorial compared with 0/25 with supratentorial stroke (p = 0.0001).Conclusions:Infratentorial stroke leading to clinical criteria for NDD occurs with an annual incidence of about 0.55 per million. There is variability in clinicians’ use of ancillary testing. Persistent CBF was detected in more than half of patients that underwent radionuclide scans. Canadian consensus is needed to guide clinical practice.
How and when perceived leader narcissism impacts employee voice behavior: a social exchange perspective
Authors: Zhang Li , Lou Ming , Guan Huihui 
Published: July 2021

AbstractDrawing from social exchange theory, this study proposes the effects of perceived leader narcissism on employees' voice behaviors (promotive voice and prohibitive voice) via organizational justice depending on the conditions of employees' trust in leader. Through investigating 257 employees and conducting a scenario study in China, this research shows that perceived leader narcissism is negatively related to prohibitive voice. The relationships between perceived leader narcissism and voice behaviors are moderated by trust in leader, and perceived leader narcissism is positively related to employees' voice behaviors when trust in leader is low. Results also show that organizational justice mediates the relationships between perceived leader narcissism and voice behaviors. The indirect effect of perceived leader narcissism on voice behaviors via organizational justice is moderated by trust in leader. This study has important implications for explaining the relationships between perceived leader narcissism and employees' voice behaviors and contributes to the social exchange theory by illustrating trust in the partner in exchange relationship as a boundary condition of norm reciprocity violation.

Published: July 2021

ABSTRACTAugusto Moreno is credited with establishing the first radiocarbon (14C) laboratory in Mexico in the 1950s, however, 14C measurement with the accelerator mass spectrometry (AMS) technique was not achieved in our country until 2003. Douglas Donahue from the University of Arizona, a pioneer in using AMS for 14C dating, participated in that experiment; then, the idea of establishing a 14C AMS laboratory evolved into a feasible project. This was finally reached in 2013, thanks to the technological developments in AMS and sample preparation with automated equipment, and the backing and support of the National Autonomous University of Mexico and the National Council for Science and Technology. The Mexican AMS Laboratory, LEMA, with a compact 1 MV system from High Voltage Engineering Europa, and its sample preparation laboratories with IonPlus automated graphitization equipment, is now a reality.
‘Ancient lore with modern appliances’: networks, expertise, and the making of the Open Polar Sea, 1851–1853

Published: July 2021

AbstractThis article provides a transnational analysis of the campaigns for the organization of expeditions to the central Arctic region by the American explorer Elisha Kent Kane and the Prussian cartographer August Petermann between 1851 and 1853. By adopting a comparative approach, this study focuses on three interventions in the history of Arctic science and exploration: the construction of scientific expertise surrounding the relationship between the ‘armchair’ and the field, the role of transnational networks, and the significance of maps as travelling epistemic objects in the production of knowledge about the Arctic regions. In bringing both campaigns in conversation with each other, this article demonstrates that the histories of Kane's and Petermann's campaigns did not constitute isolated episodes but form part of a transnational nexus of imperial science and Arctic exploration in the nineteenth century. Moreover, based on research in libraries and archives in the United States, Germany and England, this study reconnects otherwise siloed collections and contributes new findings on the interpersonal networks of science and exploration. Finally, this article illustrates the importance of adopting comparative transnational approaches for understanding the fluid and reciprocal nature of Arctic science throughout the transatlantic world.
