Published: August 2020

AbstractFiller wire metallurgy was modified through temporally shaped laser pulses, controlling cooling cycles in a recently developed method. Trends were identified through efficient mapping while maintaining representative thermal cycles of welding processes. A primary pulse melted preplaced filler wires while a secondary, linearly ramped-down pulse elevated the nugget to re-austenization temperatures. Ramped-down pulses resulted in linear cooling rates comparable with and exceeding furnace-based methods, between 50 and 300∘C/s. The linear decay of laser output power guided the temperature through a regime to obtain desired microstructures. For three very high-strength steel filler wire chemistries, quenching resulted in smaller plates with cross-hatched microstructures, accompanied by grain boundary ferrite. Finer bainite microstructures started forming for fast linear temperature decay, about 250∘C/s. Slower decay or a weaker third cycle formed coarser microstructures with coalescent sheaves and less cross-hatching.

AbstractHepatocellular carcinoma (HCC) has the tendency to invade the portal and/or hepatic venous system. The invasion of the right atrium is uncommonly observed and constitutes a treatment challenge. We report the case of a patient with HCC invading the right atrium treated with 90Yttrium-transarterial radioembolization (90Y-TARE). Following the treatment, organizing pneumonia secondary to nivolumab occurred, raising the question of an interaction between 90Y-TARE and nivolumab.
A Man’s world? Comparing the structural positions of men and women in an organized criminal network
Authors: Diviák Tomáš , Coutinho James A. , Stivala Alex D. 
Published: August 2020

AbstractThe crime gender gap is the difference between the levels of participation of men and women in crime, with men responsible for more crime than women. Recent evidence suggests that the crime gender gap is closing, both in crime in general and in organized crime. However, organized crime differs from other forms of criminal activity in that it entails an organizational structure of cooperation among offenders. Assessing whether the gender gap in organized crime is narrowing is not only about the overall levels of involvement of women, but about their roles and positions within the organized criminal structure, because the involvement of women does not mean that they are in influential positions, or that they have power or access to resources important for the commission of organized crime. This paper uses a social network approach to systematically compare the structural positions of men and women in an organized criminal network. We use a dataset collected by Canadian Law Enforcement consisting of 1390 individuals known or suspected to be involved in organized crime, 185 of whom are women. Our analysis provides evidence for an ongoing gender gap in organized crime, with women occupying structural positions that are generally associated with a lack of power. Overall, women are less present in the network, tend to collaborate with other women rather than with men, and are more often in the disadvantageous position of being connected by male intermediaries. Implications for theory and law enforcement practice are discussed.
Sample size calculations for the experimental comparison of multiple algorithms on multiple problem instances
Authors: Campelo Felipe , Wanner Elizabeth F. 
Published: August 2020

AbstractThis work presents a statistically principled method for estimating the required number of instances in the experimental comparison of multiple algorithms on a given problem class of interest. This approach generalises earlier results by allowing researchers to design experiments based on the desired best, worst, mean or median-case statistical power to detect differences between algorithms larger than a certain threshold. Holm’s step-down procedure is used to maintain the overall significance level controlled at desired levels, without resulting in overly conservative experiments. This paper also presents an approach for sampling each algorithm on each instance, based on optimal sample size ratios that minimise the total required number of runs subject to a desired accuracy in the estimation of paired differences. A case study investigating the effect of 21 variants of a custom-tailored Simulated Annealing for a class of scheduling problems is used to illustrate the application of the proposed methods for sample size calculations in the experimental comparison of algorithms.
Social Job Stressors can Foster Employee Well-Being: Introducing the Concept of Social Challenge Stressors
Authors: Kern Marcel , Heissler Clara , Zapf Dieter 
Published: August 2020

AbstractExisting social stressor concepts disregard the variety of task-related situations at work that require skillful social behavior to maintain good social relationships while achieving certain task goals. In this article, we challenge the view that social stressors at work are solely dysfunctional aspects evoking employee ill health. Drawing from the challenge-hindrance stressor framework, we introduce the concept of social challenge stressors as a job characteristic and examine their relationships with individual well-and ill-being. In study 1, we developed a new scale for the measurement of social challenge stressors and tested the validity of the scale. Results from two independent samples indicated support for a single-factor structure and showed that social challenge stressors are distinct from related stressor concepts. Using two samples, one of which was already used to test the factor structure, we analyzed the unique contribution of social challenge stressors in predicting employee well- and ill-being. As expected, social challenge stressors were simultaneously related to psychological strain and well-being. Using time-lagged data, study 2 investigated mechanisms that may explain how social challenge stressors are linked to well-being and strain. In line with the stress-as-offense-to-self approach, we expected indirect relationships via self-esteem. Additionally, social support was expected to moderate the relationships between social stressors and self-esteem. Whereas the indirect relationships were mostly confirmed, we found no support for the buffering role of social support in the social hindrance stressors-self-esteem link. Although we found a moderation effect for social challenge stressors, results indicated a compensation model that conflicted with expectations.
Single-station seismic microzonation using 6C measurements
Authors: Keil Sabrina , Wassermann Joachim , Igel Heiner 
Published: August 2020

AbstractMicrozonation is one of the essential tools in seismology to mitigate earthquake damage by estimating the near-surface velocity structure and developing land usage plans and intelligent building design. The number of microzonation studies increased in the last few years as induced seismicity becomes more relevant, even in low-risk areas. While of vital importance, especially in densely populated cities, most of the traditional techniques suffer from different shortcomings. The microzonation technique presented here tries to reduce the existing ambiguity of the inversion results by the combination of single-station six-component (6C) measurements, including three translational and three rotational motions, and more traditional H/V techniques. By applying this new technique to a microzonation study in the downtown area of Munich (Germany) using an iXblue blueSeis-3A rotational motion sensor together with a Nanometrics Trillium Compact seismometer, we were able to estimate Love and Rayleigh wave dispersion curves. These curves together with H/V spectral ratios are then inverted to obtain P- and S-wave velocity profiles of the upper 100 m. In addition, there is a good correlation between the estimated velocity models and borehole-derived lithology, indicating the potential of this single-station microzonation approach.
A structural topic model approach to scientific reorientation of economics and chemistry after German reunification
Authors: Rehs Andreas 
Published: August 2020

AbstractThe detection of differences or similarities in large numbers of scientific publications is an open problem in scientometric research. In this paper we therefore develop and apply a machine learning approach based on structural topic modelling in combination with cosine similarity and a linear regression framework in order to identify differences in dissertation titles written at East and West German universities before and after German reunification. German reunification and its surrounding time period is used because it provides a structure with both minor and major differences in research topics that could be detected by our approach. Our dataset is based on dissertation titles in economics and business administration and chemistry from 1980 to 2010. We use university affiliation and year of the dissertation to train a structural topic model and then test the model on a set of unseen dissertation titles. Subsequently, we compare the resulting topic distribution of each title to every other title with cosine similarity. The cosine similarities and the regional and temporal origin of the dissertation titles they come from are then used in a linear regression approach. Our results on research topics in economics and business administration suggest substantial differences between East and West Germany before the reunification and a rapid conformation thereafter. In chemistry we observe minor differences between East and West before the reunification and a slightly increased similarity thereafter.
What is meaningful research and how should we measure it?
Authors: Helmer Sven , Blumenthal David B. , Paschen Kathrin 
Published: August 2020

AbstractWe discuss the trend towards using quantitative metrics for evaluating research. We claim that, rather than promoting meaningful research, purely metric-based research evaluation schemes potentially lead to a dystopian academic reality, leaving no space for creativity and intellectual initiative. After sketching what the future could look like if quantitative metrics are allowed to proliferate, we provide a more detailed discussion on why research is so difficult to evaluate and outline approaches for avoiding such a situation. In particular, we characterize meaningful research as an essentially contested concept and argue that quantitative metrics should always be accompanied by operationalized instructions for their proper use and continuously evaluated via feedback loops. Additionally, we analyze a dataset containing information about computer science publications and their citation history and indicate how quantitative metrics could potentially be calibrated via alternative evaluation methods such as test of time awards. Finally, we argue that, instead of over-relying on indicators, research environments should primarily be based on trust and personal responsibility.

Abstract

Summary

Glucocorticoid use is a risk factor for osteoporosis and fractures. We studied whether women initiating glucocorticoid treatment also started anti-osteoporotic treatment, according to clinical guidelines. Women with versus without previous fracture were twice as likely to start anti-osteoporotic treatment within 1 year after initiating glucocorticoid treatment, but the cumulative incidences were low 9.1% vs. 4.6%, respectively.

Purpose
Use of glucocorticoids (GC) is a risk factor for osteoporosis and fractures, and clinical guidelines suggest that preventive treatment with anti-osteoporotic drugs (AOD) should be considered when starting GC. Women with high risk of osteoporosis comprise those with previous fractures or a known inflammatory rheumatic disease, for whom the indication of AOD is even stronger. The purpose of these analyses was to investigate whether women initiating GC treatment also started AOD, especially those with high risk of osteoporosis.

Methods
We used data from the Norwegian Prescription Database to identify all women 55 years and older initiating GC treatment in Norway during 2010–2016 and to obtain information on use of AOD. Data from the Norwegian Patient Registry were used to obtain information on previous fractures and diagnoses.

Results
Among 105,477 women initiating GC treatment during 2010–2016, 3256 had started AOD and 79,638 had discontinued GC treatment after 1-year follow-up. Cumulative incidence of starting AOD after 1 year was 9.1% (95% CI: 7.9, 10.4) for women with vs. 4.6% (95% CI: 4.4%, 4.8%) for women without a previous fracture. Women with rheumatoid arthritis or another inflammatory rheumatic disease were more likely to start AOD than women with other indications. For the whole cohort, the probability of starting AOD treatment within 1 year after initiating GC increased on average 3% per year (HR = 1.03, CI: 1.01, 1.05) from 2010 to 2016.

Conclusions
Having had a previous fracture or an inflammatory rheumatic disease increased the probability of treatment with AOD. However, the proportions starting AOD were much lower than clinically indicated.

Authors: Seyr Bernhard F. , Hoffer Thomas 
Published: August 2020

AbstractThis article focuses on the advancement of common tools in the field of measurement, visualization, and controlling of intangible assets. In this course, the fundamentals are the Boston Matrix, the McKinsey Portfolio, the life cycle analysis, and the SWOT analysis. The authors apply a hermeneutical and conceptual approach based on a literature review in order to design new instruments for portfolio analyses of intangible assets. The newly adapted tools are examined with respect to their adequacy for the strategic evaluation and development of knowledge bases in organizations. The authors introduce a Knowledge Matrix linked to a life cycle model of knowledge. Furthermore, the SWOT analysis is adjusted for the use in strategic knowledge management. The results of this paper shall be the groundwork for the implementation and evaluation of such tools in practice.
Existence of dynamical low rank approximations for random semi-linear evolutionary equations on the maximal interval
Authors: Kazashi Yoshihito , Nobile Fabio 
Published: August 2020

AbstractAn existence result is presented for the dynamical low rank (DLR) approximation for random semi-linear evolutionary equations. The DLR solution approximates the true solution at each time instant by a linear combination of products of deterministic and stochastic basis functions, both of which evolve over time. A key to our proof is to find a suitable equivalent formulation of the original problem. The so-called Dual Dynamically Orthogonal formulation turns out to be convenient. Based on this formulation, the DLR approximation is recast to an abstract Cauchy problem in a suitable linear space, for which existence and uniqueness of the solution in the maximal interval are established.

Abstract
Purpose
This cross-sectional study investigated dynamic force–time variables and vaulting performance in young female gymnasts of different maturity status.

Methods
120 gymnasts aged 5–14 years were sub-divided into maturity groupings using percent of predicted adult height (%PAH) attained. Participants performed three jumping protocols, the squat jump (SJ), countermovement jump (CMJ) and drop jump (DJ), before completing straight jump vaults that were recorded using two-dimensional video.

Results
Jumping performance improved with biological maturity evidenced by the most mature gymnasts’ producing significantly more absolute force (P < 0.05; all d > 0.78), impulse (P < 0.05; all d > 0.75) and power (P < 0.05; all d > 0.91) than the least mature group, resulting in the greater jump heights (P < 0.05; all d > 0.70). While, no significant differences were observed in relative peak force across multiple tests, measures of relative peak power did significantly increase with maturity. Based upon regression analyses, maturation was found to influence vertical take-off velocity during vaulting, explaining 41% of the variance in each jumping protocol. Across all tests, the DJ was found to have the highest predictive ability of vaulting vertical take-off velocity, explaining 55% of the total variance.

Conclusion
Biological maturation impacts jump height and underpinning mechanical variables in young female gymnasts. Vaulting vertical take-off velocity appears to be influenced by maturation and various dynamic force–time variables, particularly those during DJ, which had the highest explained total variance.
Lay Participation in Japanese Criminal Justice: Prosecution Review Commissions, the Lay-Judge System, and Penal Institution Visiting Committees
Authors: STEELE Stacey , LAWSON Carol , HIRAYAMA Mari , JOHNSON David T. 
Published: August 2020

AbstractThis article highlights reliance on lay participation as a mechanism for solving perceived problems in Japanese criminal justice by examining three reforms aimed at increasing lay participation in Japanese criminal justice: the mandatory prosecution power given to Prosecution Review Commissions, thesaiban’in seido(lay-judge system), and Penal Institution Visiting Committees. The article argues that lay participation plays an important role in legitimizing aspects of the current system. Despite the Nagoya Prison Scandal in 2002–03, Japan’s extraordinary achievements in order inside prisons have been maintained and citizens are comforted that the system has oversight by Visiting Committees. Although PRCs andsaiban’in seidorepresent a more open approach to eligibility and selection than Visiting Committees, they too help to legitimize existing structures. The article concludes by considering challenges to the continued reliance on lay participation in Japan including reform fatigue, the demographic crisis, the impact of geography, and technological developments.
Nation v. State: Constitutionalizing Transnational Nationhood, Creating Ethnizens, and Engaging with Kin-Foreigners in Europe and Asia
Authors: LEE Chulwoo 
Published: August 2020

AbstractIn the interstices of international law, quite a number of states have developed strategies to reach out to and engage with their diasporic populations or ethnonational kin outside of their borders who are not their citizens but citizens of the state in which they habitually reside. Some states even provide for that kind of policy in their Constitutions. Some states grant preferential treatment and special rights to “kin-foreigners,” thereby creating “ethnizens.” This article canvasses provisions in national Constitutions in Europe and Asia that provide grounds for engaging with the members of the nation outside of the state, analyzes the modes of engagement—mainly ethnizenship practices and various ways to strengthen links with diasporas—and examines the rules of engagement. It shows that the international norm has not provided effective guidelines regarding the strategies of transnational nation-building beyond the personal boundaries of the state and concludes that the decoupling the nation from the state registered by the transnational nationhood strategies falls short of constituting a departure from the logic of the Westphalian nation-state.
Motivated numeracy and active reasoning in a Western European sample

Published: August 2020

AbstractRecent work by Kahan et al. (2017) on the psychology of motivated numeracy in the context of intracultural disagreement suggests that people are less likely to employ their capabilities when the evidence runs contrary to their political ideology. This research has so far been carried out primarily in the USA regarding the liberal–conservative divide over gun control regulation. In this paper, we present the results of a modified replication that included an active reasoning intervention with Western European participants regarding both the hierarchy–egalitarianism and individualism–collectivism divides over immigration policy (n = 746; considerably less than the preregistration sample size). We reproduce the motivated numeracy effect, though we do not find evidence of increased polarization of high-numeracy participants.

Abstract:Background:Albeit primarily a disease of respiratory tract, the 2019 coronavirus infectious disease (COVID-19) has been found to have causal association with a plethora of neurological, neuropsychiatric and psychological effects. This review aims to analyze them with a discussion of evolving therapeutic recommendations.Methods:PubMed and Google Scholar were searched from 1 January 2020 to 30 May 2020 with the following key terms: “COVID-19”, “SARS-CoV-2”, “pandemic”, “neuro-COVID”, “stroke-COVID”, “epilepsy-COVID”, “COVID-encephalopathy”, “SARS-CoV-2-encephalitis”, “SARS-CoV-2-rhabdomyolysis”, “COVID-demyelinating disease”, “neurological manifestations”, “psychosocial manifestations”, “treatment recommendations”, “COVID-19 and therapeutic changes”, “psychiatry”, “marginalised”, “telemedicine”, “mental health”, “quarantine”, “infodemic” and “social media”. A few newspaper reports related to COVID-19 and psychosocial impacts have also been added as per context.Results:Neurological and neuropsychiatric manifestations of COVID-19 are abundant. Clinical features of both central and peripheral nervous system involvement are evident. These have been categorically analyzed briefly with literature support. Most of the psychological effects are secondary to pandemic-associated regulatory, socioeconomic and psychosocial changes.Conclusion:Neurological and neuropsychiatric manifestations of this disease are only beginning to unravel. This demands a wide index of suspicion for prompt diagnosis of SARS-CoV-2 to prevent further complications and mortality.
