Body-force and mean-line models for the generation of axial compressor sub-idle characteristics
Authors: Righi M. , Ferrer-Vidal L.E. , Pachidis V. 
Published: July 2020

ABSTRACTThis paper describes the application of low-order models to the prediction of the steady performance of axial compressors at sub-idle conditions. An Euler body-force method employing sub-idle performance correlations is developed and presented alongside a mean-line approach employing the same set of correlations. The low-order tools are used to generate the characteristic lines of the compressor in the locked-rotor and zero-torque windmilling conditions. The results are compared against steady-state operating points from three-dimensional (3D) Reynolds-averaged Navier–Stokes (RANS) computational fluid dynamics (CFD) simulations. The accuracy of the low-order tools in reproducing the results from high-fidelity CFD is analysed, and the trade-off with the computational cost of each method is discussed. The low-order tools presented are shown to offer a fast alternative to traditional CFD which can be used to predict the performance in sub-idle conditions of a new compressor design during early development stages.
Implications for Conducting Special Education Research Drawn From the Reflexive Accounts of a Deaf With Disabilities Professor and Three Student Researchers
Authors: Singer Steven , Cacciato Kimberly , Kamenakis Julianna , Shapiro Allison 
Published: July 2020

AbstractA Deaf with disabilities (DWD) male professor, 2 hearing female teacher candidates, 11 parents (4 of whom were immigrants), and 6 DWD children sought to better understand the experiences of parents of DWD children by conducting an ethnographic study (Singer, Kamenakis, Shapiro, & Cacciato, in press). The research team recorded reflexive journals as a way to analyse their methodology. In this essay, we reflect on 3 themes developed from the reflexive journals: (a) researcher positionality, (b) negotiating power in research, and (c) language variation in practice. We discuss our experiences and contextualise these accounts within relevant scholarship, attempting to locate some amount of resolution to the very human experiences upon which we reflect. We provide key takeaways for doing research with and among people with disabilities in special educational settings, particularly focusing on people who communicate in nonnormative ways. We conclude with a culminating discussion of the significance of creating emancipatory special education research.
Quantification of damages for non-pecuniary losses deriving from breach of contract
Authors: Zlatev Zlatin 
Published: July 2020

AbstractThe existing principles of quantification of damages for non-pecuniary losses deriving from breach of contract which are adopted by the courts or advanced in the legal scholarship appear to be arbitrary and founded on certain misconceptions. This paper proposes three different models for assessment based on the consequences of breach. When the performance is possible after the breach, the damages are equal to the value of an alternative subject matter if such is available from elsewhere. If there are no other sources from where the bargained-for subject matter can be obtained, then the amount of the damages is based on the value of a substitutive benefit which leads to attainment of the initial contractual aim. If the promisee has no interest in delayed performance, the damages are quantified with respect to a different non-pecuniary benefit which is commensurable to the one that was pursued with the contract initially.
The Two Faces of Party Ambiguity: A Comprehensive Model of Ambiguous Party Position Perceptions
Authors: Nyhuis Dominic , Stoetzer Lukas F. 
Published: July 2020

AbstractRecent research on electoral behavior has suggested that policy-informed vote choices are frequently obstructed by uncertainty about party positions. Given the significance of clear and distinct party platforms for meaningful representation, several studies have investigated the conditions under which parties are perceived as ambiguous. Yet previous studies have often relied on measures of perceived positional ambiguity that are fairly remote from the concept, casting doubt on their substantive conclusions. This article introduces a statistical model to estimate a comprehensive measure of perceived ambiguity that incorporates the two principal factors: non-positions and positional inconsistency. The two-faces model employs issue perceptions in an item response framework to explicitly parametrize the perceived ambiguity of party positions. The model is applied to data from the Chapel Hill Expert Survey and subsequently associated with party characteristics that drive perceptions of party ambiguity. The results suggest that (a) there are notable differences between the proposed and competing measures, highlighting the need to be mindful of the intricacies of political information processing in research on perceptions of ambiguity and (b) involuntary ambiguity might be an underexplored explanation for unclear party perceptions.
Divided by the Vote: Affective Polarization in the Wake of the Brexit Referendum
Authors: Hobolt Sara B. , Leeper Thomas J. , Tilley James 
Published: July 2020

AbstractA well-functioning democracy requires a degree of mutual respect and a willingness to talk across political divides. Yet numerous studies have shown that many electorates are polarized along partisan lines, with animosity towards the partisan out-group. This article further develops the idea of affective polarization, not by partisanship, but instead by identification with opinion-based groups. Examining social identities formed during Britain's 2016 referendum on European Union membership, the study uses surveys and experiments to measure the intensity of partisan and Brexit-related affective polarization. The results show that Brexit identities are prevalent, felt to be personally important and cut across traditional party lines. These identities generate affective polarization as intense as that of partisanship in terms of stereotyping, prejudice and various evaluative biases, convincingly demonstrating that affective polarization can emerge from identities beyond partisanship.
An Examination of the Relevance of the Codification and Application of the American Business Judgment Rule to Nigerian Corporate Law
Authors: Ubochioma Wiseman 
Published: July 2020

AbstractThe business judgment rule is an ancient doctrine that was developed in the US. It seeks to prevent courts from reviewing directors’ decisions, on the basis that directors have the capacity and expertise to make business decisions. This article examines the desirability of applying the US business judgment rule in Nigeria. Through a comparative analysis, it argues that the peculiarities of Nigeria's corporate law and environment do not justify the application of the rule. More specifically, it contends that differences in the legal regime for derivative suits, standards of duty of care and skill, corporate law culture, and the distinct epoch in which the business judgment rule and the duty of care and skill were recognized in the US, make its application unnecessary in Nigeria. It concludes that the current statutory duty of care and skill should be retained to hold directors accountable for reckless business decisions.
Gender, sexual experiences and sexual behavioural differences in Turkish university students

Published: July 2020

AbstractThis study was conducted to determine sexual experiences and gender differences in sexual behaviour in university students. In this cross-sectional and descriptive study conducted between 1st February and 12th November 2017. A total of 491 volunteer students were selected at a state university in the Mediterranean region of Turkey using a systematic sampling method. Questionnaires were distributed to the students in sealed envelopes and collected on completion. The data were collected using a socio-demographic form and a sexual experiences and sexual health behaviours form. A total of 414 students (78 males; 336 females) were included in this study. The prevalence of sexual intercourse among these was 4.3%, and total oral and anal sex experiences were 35% and 16.7%, respectively. A significantly higher number of female students of those who reported having sexual intercourse (n = 9; 50.0%), oral sex (n = 81; 55.9%) and anal sex (n = 60; 87.0%), also reported not telling anyone about his/her partner (77.2%), not talking about sex (82.4%) and not buying contraceptive products, even when necessary (78.3%). Hidden sexuality was seen to affect female students more often and this may lead to risky sexual behaviours, sexually transmitted diseases, an unhealthy sexual life with multiple partners and even unplanned, unwanted pregnancies.
Whole Person, Whole Journey: Developing a Person-Centred Regional Dementia Strategy

Published: July 2020

ABSTRACTWe present the development of a regional dementia strategy in Southwestern Ontario, Canada. We worked with stakeholders in a regional health authority to develop a dementia strategy. We conducted interviews with persons with dementia and their care partners (n = 26) and health care administrators and policy makers (n = 33); and administered a priority-setting survey (n = 64). Both participant groups identified provider compassion, professionalism, and care in the early stages of dementia as system strengths. Both groups also highlighted a need for more integration and coordination, a need for more person-centred care, support for care partners, and more flexibility in the provision and receipt of services. The highest-ranked priorities were improving care partner support, improving access to care, and improving system-wide quality. We integrate these strengths, needs, and priorities in a strategic framework, “Whole Person, Whole Journey”. Organizations developing a dementia strategy may use this framework as a springboard for their own work.
T. J. Woofter Jr. and Government Social Science Research During the New Deal, World War II, and the Cold War
Authors: ELLIS MARK 
Published: July 2020

AbstractThe work of southern sociologist Thomas Jackson Woofter Jr. (1893–1972) is frequently cited by American historians, but his contribution to government policy on agriculture in the New Deal, Social Security in the 1940s, and demography in the Cold War remains underappreciated. He left the University of North Carolina to direct government research on rural relief in the 1930s, Social Security enhancement during and after World War II, and foreign population and manpower projections during the Cold War. Contributing to the delivery of essential programs in key agencies, he participated in internal and external debates over policy and social attitudes between 1930 and 1960. Woofter worked for the Federal Emergency Relief Administration, the Works Progress Administration, the Farm Security Agency, the Federal Security Agency, and the Central Intelligence Agency, improving data-gathering and assisting transitions in federal policymaking. This article assesses his role in those agencies, using official records, other primary materials, and secondary sources.
Cognitive behavioural therapy for co-morbid anxiety and depression in heart failure: a case report
Authors: Slaughter Charlotte , Allen Chris 
Published: July 2020

Abstract
Heart failure increases the likelihood of an individual experiencing co-morbid anxiety and depression, which can affect their physical as well as mental health. There is a need to develop non-pharmacological interventions for the psychological consequences of heart failure. Evidence shows that cognitive behavioural therapy (CBT) can be helpful, but there is less clarity about CBT’s effectiveness for people with heart failure who have complex multi-morbid difficulties.
This paper presents a case report of a man with heart failure. He was part of a research trial for cardiac resynchronisation therapy with defibrillation (CRT-D), after other physical procedures had been unsuccessful, and was experiencing severe anxiety and moderately severe depression. The intervention used was based on transdiagnostic CBT, provided at home over six sessions. Self-report measures were completed at each session and at 3-month follow-up. A measure of his use of clinical services was also carried out at pre-, post- and 3-month follow up. Post-intervention, the client showed non-clinical levels of depression and anxiety and these improvements were maintained at 3 months. Use of clinical services also reduced, with fewer admissions to hospital and fewer visits by specialist nurses and GPs.
This case suggests that CBT, and particularly transdiagnostic CBT, can be helpful in reducing anxiety and depression in people with heart failure. Further work evaluating the impact on quality of life and the utility of this approach with a wider group of people with heart failure and psychological distress would be advantageous.

Key learning aims

(1)
Depression and anxiety are prevalent in people with heart failure.

(2)
Cognitive behavioural therapy can be an effective intervention for reducing depression and anxiety in people living with heart failure.

(3)
There are benefits to integrating care with this population because they present with interlinked physical and psychological needs.
Towards a model of uncertainty distress in the context of Coronavirus (COVID-19)
Authors: Freeston Mark , Tiplady Ashley , Mawn Lauren , Bottesi Gioia , Thwaites Sarah 
Published: July 2020

AbstractThe paper forms part of a series of papers outlining the theoretical framework for a new model of uncertainty distress (this paper), treatment implications arising from the model, and empirical tests of the model. We define uncertainty distress asthe subjective negative emotions experienced in response to the as yet unknown aspects of a given situation. In the first paper we draw on a robust body of research on distinct areas including: threat models of anxiety, perceived illness uncertainty and intolerance of uncertainty. We explore how threat and uncertainty are separable in anxiety and how we can understand behaviours in response to uncertainty. Finally, we propose a clinically, theoretically and empirically informed model for uncertainty distress, and outline how this model can be tested. Caveats, clinical applications and practitioner key points are briefly included, although these are more fully outlined in the treatment implications article. While we outline this model in the context of novel coronavirus (COVID-19), the model has broader applications to both mental and physical health care settings.Key learning aims(1)To define the concept of uncertainty distress.(2)To understand the role of threat, over-estimation of threat, perceived uncertainty, actual uncertainty, and intolerance of uncertainty in distress maintenance.(3)To understand how people may behave in response to uncertainty distress.(4)To describe a model of uncertainty distress.
Increased Climate Response and Earth System Sensitivity From CCSM4 to CESM2 in Mid‐Pliocene Simulations
Authors: Feng Ran , Otto‐Bliesner Bette L. , Brady Esther C. , Rosenbloom Nan 
Published: July 2020

AbstractThree new equilibrium mid‐Pliocene (MP) simulations are implemented with the Community Climate System Model version 4 (CCSM4) and Community Earth System Model versions 1.2 (CESM1.2) and 2 (CESM2). All simulations are carried out with the same boundary and forcing conditions following the protocol of Pliocene Model Intercomparison Project Phase 2 (PlioMIP2). These simulations reveal amplified MP climate change relative to the preindustrial going from CCSM4 to CESM2, seen in global and polar averages of surface warming, sea ice reduction in both the Arctic and the Antarctic, and weakened Hadley circulation. The enhanced global mean warming arises from enhanced Earth system sensitivity (ESS) to not only CO2change but also changes in boundary conditions primarily from vegetation and ice sheets. ESS is amplified by up to 70% in CCSM4 and up to 100% in CESM1.2 and CESM2 relative to the equilibrium climate sensitivity of respective models. Simulations disagree on several climate metrics. Different from CCSM4, both CESM1.2 and CESM2 show reduction of cloud cover, and weakened Walker circulation accompanied by an El Niño‐like mean state of the tropical Pacific in MP simulations relative to the preindustrial. This El Niño‐like mean state is consistent with paleo‐observational sea surface temperatures, suggesting an improvement upon CCSM4. The performances of MP simulations are assessed with a new compilation of observational MP sea surface temperature. The model‐data comparison suggests that CCSM4 is not sensitivity enough to the MP forcings, but CESM2 is likely too sensitive, especially in the tropics.
Particle Simulation of the Generation of Plasmaspheric Hiss
Authors: Hikishima Mitsuru , Omura Yoshiharu , Summers Danny 
Published: July 2020

AbstractWe have conducted a one‐dimensional electromagnetic particle simulation with a parabolic magnetic field to reproduce whistler‐mode hiss emissions in the plasmasphere. We assume a bi‐Maxwellian distribution with temperature anisotropy for energetic electrons injected into the plasmasphere and find that hiss emissions are generated with spectrum characteristics typical of those observed by spacecraft near the magnetic equator. The hiss emissions contain fine structures involving rising tone and falling tone elements with variation in frequencies. The amplitude profile of the spectra agrees with the optimum wave amplitude derived from the nonlinear wave growth theory. The simulation demonstrates that hiss emissions are generated locally near the magnetic equator through linear and nonlinear interactions with energetic electrons with temperature anisotropy. The coherent hiss emissions efficiently scatter resonant electrons of 2.5–80 keV into the loss cone.
Technical Report—Methods: A Diagnostic Approach to Analyze the Direction of Change in Model Outputs Based on Global Variations in the Model Inputs
Authors: Wang Anqi , Pianosi Francesca , Wagener Thorsten 
Published: July 2020

AbstractHydrologic models are used to simulate natural phenomena while making different assumptions about the levels of complexity with which natural processes should be represented. Global Sensitivity Analysis is regularly applied to understand how the inputs (including forcing, parameters, and initial states) of these models control their outputs. A less widely explored strategy to support such diagnostic analysis is the assessment of direction of change (DOC), which addresses the question whether the increase (or decrease) of a model input leads to a positive (or negative) change in the model output. We propose a metric, called Direction Index, to quantitatively assess the DOC and develop an approach to calculate it. The basic idea of our approach is twofolded: (1) Estimate the zeroth and first‐order term of the High Dimensional Model Representation (HDMR) decomposition. (2) Calculate the derivatives of the first‐order term of the HDMR decomposition with respect to a given input. We demonstrate our approach on a widely used conceptual lumped hydrological model (Hymod) with a time‐varying analysis applied to the Leaf River Catchment in the USA. The results show that our approach provides new insights into the behavior of the model, which can be used to guide model structure improvement or to improve calibration efficiency.
Intranasal oxytocin modulates brain responses to voice-identity recognition in typically developing individuals, but not in ASD
Authors: Borowiak Kamila , von Kriegstein Katharina 
Published: July 2020

AbstractFaces and voices are prominent cues for person-identity recognition. Face recognition behavior and associated brain responses can be enhanced by intranasal administration of oxytocin. It is unknown whether oxytocin can also augment voice-identity recognition mechanisms. To find it out is particularly relevant for individuals who have difficulties recognizing voice identity such as individuals diagnosed with autism spectrum disorder (ASD). We conducted a combined behavioral and functional magnetic resonance imaging (fMRI) study to investigate voice-identity recognition following intranasal administration of oxytocin or placebo in a group of adults diagnosed with ASD (full-scale intelligence quotient > 85) and pairwise-matched typically developing (TD) controls. A single dose of 24 IU oxytocin was administered in a randomized, double-blind, placebo-controlled and cross-over design. In the control group, but not in the ASD group, administration of oxytocin compared to placebo increased responses to recognition of voice identity in contrast to speech in the right posterior superior temporal sulcus/gyrus (pSTS/G) — a region implicated in the perceptual analysis of voice-identity information. In the ASD group, the right pSTS/G responses were positively correlated with voice-identity recognition accuracy in the oxytocin condition, but not in the placebo condition. Oxytocin did not improve voice-identity recognition performance at the group level. The ASD compared to the control group had lower right pSTS/G responses to voice-identity recognition. Since ASD is known to have atypical pSTS/G, the results indicate that the potential of intranasal oxytocin to enhance mechanisms for voice-identity recognition might be variable and dependent on the functional integrity of this brain region.
The role of omega-3 fatty acids in preventing glucocorticoid-induced reduction in human hippocampal neurogenesis and increase in apoptosis

Published: July 2020

AbstractGlucocorticoids have been suggested to be involved in several neuropsychiatric disorders, including depression. One of the possible mechanisms through which glucocorticoids contribute to the development of the depressive symptomatology is via regulation of distinct neurogenic mechanisms in the brain. A preventive or protective approach for these patients might be the use of omega-3 polyunsaturated fatty acids (n-3 PUFAs), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are known for they neuroprotective properties. We used the human hippocampal progenitor cell line HPC0A07/03C and pre-treated cells with either EPA or DHA, followed by treatment with the glucocorticoid cortisol either alone, or in co-treatment with the same n-3 PUFA during subsequent 3 days of proliferation and 7 days of differentiation. During proliferation, both EPA and DHA were able to prevent cortisol-induced reduction in proliferation and increase in apoptosis, when used in pre-treatment, and both pre- and co-treatment. During differentiation, EPA was able to prevent cortisol-induced reduction in neurogenesis and increase in apoptosis, when used in pre-treatment, and both pre- and co-treatment only during the proliferation stage; however, DHA required continuous treatment also during the differentiation stage to prevent cortisol-induced reduction in neurogenesis. Using transcriptomic analyses, we showed that both EPA and DHA regulated pathways involved in oxidative stress and immune response [e.g., nuclear factor (erythroid-derived 2)-like 2 (Nrf2), Signal transducer and activator of transcription 3 (STAT3), Interferon (IFN) and Interleukin (IL)-1 signaling], whereas DHA also regulated pathways involved in cell development and neuronal formation [e.g., cAMP-response element binding protein (CREB) signaling]. We provide the first evidence for treatment with both EPA and DHA to prevent cortisol-induced reduction in human hippocampal neurogenesis, and identify novel molecular mechanisms underlying these effects.
