Improving earthquake ground-motion predictions for the North Sea
Authors: Brooks Christopher , Douglas John , Shipton Zoe 
Published: February 2020

AbstractEstimates of the expected ground motion are essential for the design, assessment and decommissioning of offshore critical infrastructure. The North Sea is an area of moderate seismic hazard that contains many high-value offshore structures (e.g. oil, gas and wind-turbine facilities). The most recent seismic hazard assessment for the North Sea is about 20 years old, before many innovations in ground-motion modelling were developed. In this study, firstly we investigate which ground-motion model from more than a dozen recent models is the most appropriate for this area based on a residual analysis of ground-motion data from onshore seismic stations surrounding the North Sea. The limited data that are available for this area and the poor magnitude and distance coverage are inherent weaknesses of this residual analysis. A recent model developed for Europe and the Middle East is the model that shows the lowest bias and minimal statistical trends with respect to magnitude and distance. Following this, we develop adjustments to this best-performing model to relax the ergodic assumption, i.e. to make the model more site- and path-specific thereby allowing a smaller aleatory variability (sigma) to be used within a probabilistic seismic hazard assessment. The use of this adjusted model within seismic hazard assessments for the North Sea should lead to better estimates of the expected ground motion for critical offshore infrastructure sites, although this would require the effects of the geotechnical properties of the seafloor to be accounted for.
Benders decomposition for the mixed no-idle permutation flowshop scheduling problem
Authors: Bektaş Tolga , Hamzadayı Alper , Ruiz Rubén 
Published: February 2020

AbstractThe mixed no-idle flowshop scheduling problem arises in modern industries including integrated circuits, ceramic frit and steel production, among others, and where some machines are not allowed to remain idle between jobs. This paper describes an exact algorithm that uses Benders decomposition with a simple yet effective enhancement mechanism that entails the generation of additional cuts by using a referenced local search to help speed up convergence. Using only a single additional optimality cut at each iteration, and combined with combinatorial cuts, the algorithm can optimally solve instances with up to 500 jobs and 15 machines that are otherwise not within the reach of off-the-shelf optimization software, and can easily surpass ad-hoc existing metaheuristics. To the best of the authors’ knowledge, the algorithm described here is the only exact method for solving the mixed no-idle permutation flowshop scheduling problem.
Policy processes sans frontières: interactions in transnational governance of global health
Authors: Jones Catherine M. , Clavier Carole , Potvin Louise 
Published: February 2020

AbstractNational policy on global health (NPGH) arenas are multisectoral governing arrangements for cooperation between health, development, and foreign affairs sectors in government policy for global health governance. To explore the relationship between national and global processes for governing global health, this paper asks: in what forms of interaction between NPGH arenas and global health governance are learning and networking processes present? In a multiple case study of Norwegian and Swiss NPGH arenas, we collected data on intersectoral policy processes from semi-structured interviews with 33 informants in 2014-2015. Adapting Real-Dato’s framework, we analyzed each case separately, producing monographs for comparing NPGH arenas. Analyzing both NPGH arenas for relational structures linking external resources to internal policy arena processes, we found five zones of interactions - including institutions, transgovernmental clubs, and connective forms. These interactions circulate ideas and soften arenas’ boundaries. We argue that NPGH is characteristic of transnational governance of global health.
On the Willingness to Report and the Consequences of Reporting Research Misconduct: The Role of Power Relations
Authors: Horbach Serge P. J. M. , Breit Eric , Halffman Willem , Mamelund Svenn-Erik 
Published: February 2020

AbstractWhile attention to research integrity has been growing over the past decades, the processes of signalling and denouncing cases of research misconduct remain largely unstudied. In this article, we develop a theoretically and empirically informed understanding of the causes and consequences of reporting research misconduct in terms of power relations. We study the reporting process based on a multinational survey at eight European universities (N = 1126). Using qualitative data that witnesses of research misconduct or of questionable research practices provided, we aim to examine actors’ rationales for reporting and not reporting misconduct, how they report it and the perceived consequences of reporting. In particular we study how research seniority, the temporality of work appointments, and gender could impact the likelihood of cases being reported and of reporting leading to constructive organisational changes. Our findings suggest that these aspects of power relations play a role in the reporting of research misconduct. Our analysis contributes to a better understanding of research misconduct in an academic context. Specifically, we elucidate the processes that affect researchers’ ability and willingness to report research misconduct, and the likelihood of universities taking action. Based on our findings, we outline specific propositions that future research can test as well as provide recommendations for policy improvement.
In Search of a Unified Theory of Sensory Perception: Possible Links between the Vibrational Mechanism of Olfaction and the Evolution of Language
Authors: Lewis Amelia 
Published: February 2020

AbstractHere, I outline the idea of a unified hypothesis of sensory perception, developed from the theoretical vibrational mechanism of olfaction, which can be applied across all sensory modalities. I propose that all sensory perception is based upon the detection of mechanical forces at a cellular level, and the subsequent mechanotransduction of the signal via the nervous system. Thus, I argue that the sensory modalities found in the animal kingdom may all be viewed as being mechanoreceptory, rather than being discrete neurophysiological systems which evolved independently of each other. I go on to argue that this idea could potentially explain language evolution, with birdsong being an example of a more simple form of non-Saussurean language that employs ‘frequency-mimicking’ to produce a vocal signal which describes acoustic, chemical and electromagnetic vibrational frequencies detected within in the environment. I also give examples of how this hypothesis could potentially explain phenomena such as vocal mimicry in animals, as well as the human perception of musicality and the occurrence of synaesthesia; a condition found in humans, where the stimulation of one sensory modality results in the stimulation of another. For example, auditory stimuli are detected and are heard as an acoustic signal, as well as being perceived as colour by the visual system.
The Characterization of Pre-insolvency Proceedings in Private International Law
Authors: Mevorach Irit , Walters Adrian 
Published: February 2020

AbstractThe decade since the financial crisis has witnessed a proliferation of various ‘light touch’ financial restructuring techniques in the form of so-called pre-insolvency proceedings. These proceedings inhabit a space on the spectrum of insolvency and restructuring law, somewhere between a pure contractual workout, the domain of contract law, and a formal insolvency or rehabilitation proceeding, the domain of insolvency law. While, to date, international insolvency instruments have tended to define insolvency proceedings quite expansively, discussion of the cross-border implications of pre-insolvency proceedings has barely begun. The question is whether pre-insolvency proceedings should qualify as proceedings related to insolvency for the purpose of private international law characterization. The risk is over-inclusivity of cross-border insolvency law, which, where it is based on universality and unity, might defeat contractual expectations. This article argues, however, that we should be slow to exclude pre-insolvency proceedings from cross-border insolvency law: these proceedings are initiated in the zone of insolvency, their effectiveness depends on a statutory mandate and not purely on private ordering, they interact and intersect with formal proceedings, and can benefit from the unique system developed by cross-border insolvency law. We suggest, though, that modified universalism (the leading norm of cross-border insolvency) and international insolvency instruments, should, and are able to, adjust to the peculiarities of pre-insolvency proceedings to address concerns about inclusivity and accommodate pre-insolvency proceedings adequately.
European Society for Sexual Medicine Position Statement “Assessment and Hormonal Management in Adolescent and Adult Trans People, with Attention for Sexual Function and Satisfaction”
Authors: T'Sjoen Guy , Arcelus Jon , De Vries Annelou L.C. , Fisher Alessandra D. , Nieder Timo O. , Özer Müjde , Motmans Joz 
Published: February 2020

Abstract

Background
There is a general lack of recommendations for and basic information tailored at sexologists and other health-care professionals for when they encounter trans people in their practice.

Aim
We present to clinicians an up-to-date overview of clinical consensus statements on trans health care with attention for sexual function and satisfaction.

Methods
The task force consisted of 7 clinicians experienced in trans health care, selected among European Society for Sexual Medicine (ESSM) scientific committee. The consensus was guided by clinical experience and a review of the available literature and by interactive discussions on trans health, with attention for sexual function and satisfaction where available.

Outcomes
The foci of the study are assessment and hormonal aspects of trans health care.

Results
As the available literature for direct recommendations was limited, most of the literature was used as background or indirect evidence. Clinical consensus statements were developed based on clinical experiences and the available literature. With the multiple barriers to care that many trans people experience, basic care principles still need to be stressed. We recommend that health-care professionals (HCPs) working with trans people recognize the diversity of genders, including male, female, and nonbinary individuals. In addition, HCPs assessing gender diverse children and adolescents should take a developmental approach that acknowledges the difference between prepubescent gender diverse children and pubescent gender diverse adolescents and trans adults. Furthermore, trans people seeking gender-affirming medical interventions should be assessed by HCPs with expertise in trans health care and gender-affirming psychological practice. If masculinization is desired, testosterone therapy with monitoring of serum sex steroid levels and signs of virilization is recommended. Similarly, if feminization is desired, we recommend estrogens and/or antiandrogen therapy with monitoring of serum sex steroid levels and signs of feminization. HCPs should be aware of the influence of hormonal therapy on sexual functioning and satisfaction. We recommend HCPs be aware of potential sexual problems during all surgical phases of treatment.

Clinical Implications
This is an up-to-date ESSM position statement.

Strengths & Limitations
These statements are based on the data that are currently available; however, it is vital to recognize that this is a rapidly changing field and that the literature, particularly in the field of sexual functioning and satisfaction, is limited.

Conclusion
This ESSM position statement provides relevant information and references to existing clinical guidelines with the aim of informing relevant HCPs on best practices when working with transgender people.
Rural Residence and Diagnostic Delay for Amyotrophic Lateral Sclerosis in Saskatchewan
Authors: Armstrong Melissa Diane , Hansen Gregory , Schellenberg Kerri Lynn 
Published: February 2020

ABSTRACT:Background:Diagnostic delay in amyotrophic lateral sclerosis (ALS) is common. In a recent Canadian study evaluating provincial differences in care, Saskatchewan had the longest delay at 27 months. Since Saskatchewan has a large rural population, this study sought to determine whether geographically determined access to a neurologist at tertiary centers could be contributing to this lengthy delay.Methods:A retrospective chart review of 171 patients seen in the ALS clinic in Saskatoon, Saskatchewan was performed. Urban or rural location, distance from nearest tertiary center, and clinically relevant data were collected.Results:There was no difference between urban and rural populations for delay in symptom onset to diagnosis. For rural patients, linear regression modeling did not uncover a significant relationship between distance from tertiary center and time to diagnosis. Additionally, there were no differences between urban and rural dwellers either for referral or utilization of feeding tube, noninvasive ventilation, riluzole, or communication devices. Contrary to the previous data showing a 27-month diagnostic delay in Saskatchewan, our study which included a larger provincial population found the mean diagnostic delay was 16.6 months.Conclusions:This study did not uncover differences in diagnostic delay or ALS care between urban and rural dwellers. Further study is required to determine reproducibility of results.

Published: February 2020

AbstractObjective:To compare the microbicidal activity of low-temperature sterilization technologies (vaporized hydrogen peroxide [VHP], ethylene oxide [ETO], and hydrogen peroxide gas plasma [HPGP]) to steam sterilization in the presence of salt and serum to simulate inadequate precleaning.Methods:Test carriers were inoculated with Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, vancomycin-resistant Enterococcus, Mycobacterium terrae, Bacillus atrophaeus spores, Geobacillus stearothermophilus spores, or Clostridiodes difficile spores in the presence of salt and serum and then subjected to 4 sterilization technologies: steam, ETO, VHP and HPGP.Results:Steam, ETO, and HPGP sterilization techniques were capable of inactivating the test organisms on stainless steel carriers with a failure rate of 0% (0 of 220), 1.9% (6 of 310), and 1.9% (5 of 270), respectively. The failure rate for VHP was 76.3% (206 of 270).Conclusion:Steam sterilization is the most effective and had the largest margin of safety, followed by ETO and HPGP, but VHP showed much less efficacy.
Strengths and difficulties questionnaire-teacher: Investigating its factor structure and utility with culturally and linguistically diverse students
Authors: Khawaja Nigar G. , Dhushyanthakumar Lakshmi 
Published: February 2020

AbstractThe Strengths and Difficulties Questionnaire (SDQ), with its three forms (youth, parent and teacher version), is widely used to assess emotional and behavioural disorders in children and adolescents. The present study examined the factor structure and psychometric properties of the teacher version of the scale (SDQ-T) with adolescents from culturally and linguistically diverse (CALD) background. It also explored the impact of demographic factors on the mental health outcomes of CALD adolescents in the school setting as indicated by SDQ-T. Teachers from a Special English language transitional school in Brisbane, Australia completed the SDQ-T for 175 culturally and linguistically diverse adolescents. The exploratory factor analysis indicated a 23-item scale with a four-factor structure: Prosocial Behaviour, Hyperactivity, Emotional Symptoms, and Behavioural Problems. The revised scale had sound internal consistency. Findings indicated that CALD adolescents from refugee backgrounds scored higher on Emotional Symptoms, Conduct and Peer Problems, and SDQ total difficulties. There were no differences on subscale scores based on gender or English language proficiency. SDQ-T emerged as a promising scale that can be used to understand CALD adolescents’ postmigration emotional experiences, risks and protective factors. The implications of the SDQ-T in schools with adolescents from migrant and refugee backgrounds are discussed.
The Burgess Shale paleocommunity with new insights from Marble Canyon, British Columbia
Authors: Nanglu Karma , Caron Jean-Bernard , Gaines Robert R. 
Published: February 2020

AbstractThe middle (Wuliuan Stage) Cambrian Burgess Shale is famous for its exceptional preservation of diverse and abundant soft-bodied animals through the “thick” Stephen Formation. However, with the exception of the Walcott Quarry (Fossil Ridge) and the stratigraphically older Tulip Beds (Mount Stephen), which are both in Yoho National Park (British Columbia), quantitative assessments of the Burgess Shale have remained limited. Here we first provide a detailed quantitative overview of the diversity and structure of the Marble Canyon Burgess Shale locality based on 16,438 specimens. Located 40 km southeast of the Walcott Quarry in Kootenay National Park (British Columbia), Marble Canyon represents the youngest site of the “thick” Stephen Formation. We then combine paleoecological data sets from Marble Canyon, Walcott Quarry, Tulip Beds, and Raymond Quarry, which lies approximately 20 m directly above the Walcott Quarry, to yield a combined species abundance data set of 77,179 specimens encompassing 234 species-level taxa. Marble Canyon shows significant temporal changes in both taxonomic and ecological groups, suggesting periods of stasis followed by rapid turnover patterns at local and short temporal scales. At wider geographic and temporal scales, the different Burgess Shale sites occupy distinct areas in multivariate space. Overall, this suggests that the Burgess Shale paleocommunity is far patchier than previously thought and varies at both local and regional scales through the “thick” Stephen Formation. This underscores that our understanding of Cambrian diversity and ecological networks, particularly in early animal ecosystems, remains limited and highly dependent on new discoveries.

Published: February 2020

AbstractThis study aimed to investigate the association between 25-hydroxyvitamin D (25(OH)D) level and low back pain (LBP) among adolescents while adjusting for potential confounders pertinent to this age group including the weight of school bags, BMI and physical activity. A cross-sectional study was conducted on 760 randomly selected adolescents in middle schools. Data on LBP and the risk factors for LBP were collected from parents by a self-administered questionnaire and from adolescents by face-to-face interview. Blood samples were tested in an accredited laboratory; and 25(OH)D was measured using liquid chromatography-tandem MS. The lifetime prevalence and the 6-month prevalence of LBP were 32·28 (95 % CI 28·97, 35·73) % and 21·26 (95 % CI 18·40, 24·33) %, respectively. There was no difference in the geometric mean of 25(OH)D between those with and without LBP in the past 6 months (28·50 nmol/l and 30·82 nmol/l, respectively;P= 0·122). There was no association between 25(OH)D and LBP in the univariable or multivariable analysis whether 25(OH)D fitted as a continuous or as a categorical variable. We found no association between vitamin D level and LBP in adolescents in an area with high prevalence of vitamin D deficiency. Although it is important to have sufficient vitamin D levels during adolescence for several other health benefits, we concluded that vitamin D is not a major determinant for LBP among adolescents in our setting.
Evaluating the radiation contamination dose around a high dose per pulse intraoperative radiotherapy accelerator: a Monte Carlo study

Published: February 2020

AbstractAim:In this study, the radiation contamination dose (RCD) for different combinations of electron energy/distance, applicator and radius around the light intraoperative accelerator (LIAC), a high dose per pulse dedicated intraoperative electron radiotherapy machine, has been estimated. Being aware about the amount of RCDs is highly recommended for linear medical electron accelerators.Methods and methods:Monte Carlo Nuclear Particles (MCNP) code was used to simulate the LIAC® head and calculate RCDs. Experimental RCDs measurements were also done by Advanced Markus chamber inside a MP3-XS water phantom. Relative differences of simulations and measurements were calculated.Result:RCD reduction by distance from the machine follows the inverse-square law, as expected. The RCD was decreased by increasing angle from applicator walls opposed to the electron beam direction. The maximum differences between the simulation and measurement results were lower than 3%.Conclusions:The RCD is strongly dependent on electron beam energy, applicator size and distance from the accelerator head. Agreement between the MCNP results and ionometric dosimetry confirms the applicability of this simulation code in modelling the intraoperative electron beam and obtaining the dosimetric parameters. The RCD is a parameter that would restrict working with LIAC in an unshielded operative room.
SHGAPE Presidential Address: Mind the GAPE: Globality and the Rural Midwest
Authors: Hoganson Kristin 
Published: February 2020

AbstractThis essay, originally delivered as the SHGAPE Presidential Address in April 2019, takes as a starting point the fiftieth anniversary of William Appleman Williams'sThe Roots of the Modern American Empire: A Study of the Growth and Shaping of Social Consciousness in a Marketplace Society.It finds that Williams's claims about the agrarian roots of the modern American empire remain an important corrective to imperial denial, including to the stubborn idea of the American heartland as a locus of isolationist impulses, as a place better characterized as endangered by global forces than as a wellspring of power. Broadening out beyond Williams's export-centered analysis, this essay highlights some of the multi-directional links that connected the rural heartland to the wider world in the late nineteenth and early twentieth centuries. By turning a seemingly local history inside out, it draws attention to longer histories of settler colonialism, the import side of trade ledgers, transimperial solidarities, and the networks of anticolonial resistance that emerged in land grant colleges. In addition to reframing nationalist mythologies more precisely as white nationalist mythologies, it concludes that there is no going back to the heartland of myth because it never existed in the first place.
