Published: December 2019

AbstractThis paper provides several theoretical results for empirical game theory. Specifically, we introduce bounds for empirical game theoretical analysis of complex multi-agent interactions. In doing so we provide insights in the empirical meta game showing that a Nash equilibrium of the estimated meta-game is an approximate Nash equilibrium of the true underlying meta-game. We investigate and show how many data samples are required to obtain a close enough approximation of the underlying game. Additionally, we extend the evolutionary dynamics analysis of meta-games using heuristic payoff tables (HPTs) to asymmetric games. The state-of-the-art has only considered evolutionary dynamics of symmetric HPTs in which agents have access to the same strategy sets and the payoff structure is symmetric, implying that agents are interchangeable. Finally, we carry out an empirical illustration of the generalised method in several domains, illustrating the theory and evolutionary dynamics of several versions of theAlphaGoalgorithm (symmetric), the dynamics of the Colonel Blotto game played by human players on Facebook (symmetric), the dynamics of several teams of players in the capture the flag game (symmetric), and an example of a meta-game in Leduc Poker (asymmetric), generated by the policy-space response oracle multi-agent learning algorithm.
Solving the shift and break design problem using integer linear programming
Authors: Akkermans Arjan , Post Gerhard , Uetz Marc 
Published: December 2019

AbstractIn this paper we propose a two-phase approach to solve the shift and break design problem using integer linear programming. In the first phase we create the shifts, while heuristically taking the breaks into account. In the second phase we assign breaks to each occurrence of any shift, one by one, repeating this until no improvement is found. On a set of benchmark instances, composed by both randomly-generated and real-life ones, this approach obtains better results than the current best known method for shift and break design problem.

AbstractGenome-wide studies often exclude family members, even though they are a valuable source of information. We identified parent–offspring pairs, siblings and couples in the UK Biobank and implemented a family-based DNA-derived heritability method to capture additional genetic effects and multiple sources of environmental influence on neuroticism and years of education. Compared to estimates from unrelated individuals, total heritability increased from 10 to 27% and from 17 to 56% for neuroticism and education respectively by including family-based genetic effects. We detected no family environmental influences on neuroticism. The couple similarity variance component explained 35% of the variation in years of education, probably reflecting assortative mating. Overall, our genetic and environmental estimates closely replicate previous findings from an independent sample. However, more research is required to dissect contributions to the additional heritability by rare and structural genetic effects, assortative mating, and residual environmental confounding. The latter is especially relevant for years of education, a highly socially contingent variable, for which our heritability estimate is at the upper end of twin estimates in the literature. Family-based genetic effects could be harnessed to improve polygenic prediction.
Communication of IPCC visuals: IPCC authors’ views and assessments of visual complexity

Published: December 2019

AbstractScientific figures, i.e. visuals such as graphs and diagrams, are an important component of Intergovernmental Panel on Climate Change (IPCC) reports that support communication and policy-making. It is therefore imperative that figures are robust representations of the science and are accessible to target audiences. We interviewed IPCC authors (n = 18) to understand the development of figures in the IPCC Fifth Assessment Report (AR5) Working Group 1 (WG1) Summary for Policy-Makers (SPM). Authors expressed the view that the need to maintain scientific accuracy constrained making figures more accessible, with the consequence that figures retained complexity and often required specialists to explain the figures to others. Using sort tasks with IPCC authors and with a group of non-specialists (undergraduate students; n = 38), we found that IPCC authors generally had good awareness of which figures non-specialists perceived as being most difficult to understand. Further, by evaluating the visual complexity of the AR5 WG1 SPM figures using a computational measure, we found that greater visual complexity (i.e. high quantity of information, use of multiple colours and densely packed visual elements) is associated with greater perceived comprehension difficulty. Developing and integrating computational approaches to assess figures alongside user testing could help inform how to overcome visual complexity while maintaining scientific rigour and so enhance communication of IPCC figures and scientific visuals.
Countrywide climate features during recorded climate-related disasters
Authors: Tschumi Elisabeth , Zscheischler Jakob 
Published: December 2019

AbstractClimate-related disasters cause substantial disruptions to human societies. With climate change, many extreme weather and climate events are expected to become more severe and more frequent. The International Disaster Database (EM-DAT) records climate-related disasters associated with observed impacts such as affected people and economic damage on a country basis. Although disasters are classified into different meteorological categories, they are usually not linked to observed climate anomalies. Here, we investigate countrywide climate features associated with disasters that have occurred between 1950 and 2015 and have been classified as droughts, floods, heat waves, and cold waves using superposed epoch analysis. We find that disasters classified as heat waves are associated with significant countrywide increases in annual mean temperature of on average 0.13 ∘C and a significant decrease in annual precipitation of 3.2%. Drought disasters show positive temperature anomalies of 0.08 ∘C and a 4.8 % precipitation decrease. Disasters classified as droughts and heat waves are thus associated with significant annual countrywide anomalies in both temperature and precipitation. During years of flood disasters, precipitation is increased by 2.8 %. Cold wave disasters show no significant signal for either temperature or precipitation. We further find that climate anomalies tend to be larger in smaller countries, an expected behavior when computing countrywide averages. In addition, our results suggest that extreme weather disasters in developed countries are typically associated with larger climate anomalies compared to developing countries. This effect could be due to different levels of vulnerability, as a climate anomaly needs to be larger in a developed country to cause a societal disruption. Our analysis provides a first link between recorded climate-related disasters and observed climate data, which is an important step towards linking climate and impact communities and ultimately better constraining future disaster risk.

Published: December 2019

AbstractThe forests of the Albertine Rift are known for their high biodiversity and the important ecosystem services they provide to millions of inhabitants. However, their conservation and the maintenance of ecosystem service delivery is a challenge, particularly in the Democratic Republic of the Congo. Our research investigates how livelihood strategy and ethnicity affects local perceptions of forest ecosystem services. We collected data through 25 focus-group discussions in villages from distinct ethnic groups, including farmers (Tembo, Shi, and Nyindu) and hunter-gatherers (Twa). Twa identify more food-provisioning services and rank bush meat and honey as the most important. They also show stronger place attachment to the forest than the farmers, who value other ecosystem services, but all rank microclimate regulation as the most important. Our findings help assess ecosystem services trade-offs, highlight the important impacts of restricted access to forests resources for Twa, and point to the need for developing alternative livelihood strategies for these communities.
The fiscal aspect of the refugee crisis
Authors: Ruist Joakim 
Published: December 2019

AbstractAn important part of the resistance to higher refugee immigration in rich countries is due to the fear of the negative fiscal consequences. Yet this article shows that the fiscal consequences even of substantially increased refugee immigration are likely to be quite modest. According to the estimates, if the European Union received all refugees currently in Asia and Africa, the implied average annual fiscal cost over the lifetime of these refugees would be at most 0.6% of the union’s GDP. If other rich countries also shared the burden, the cost per country would be even lower.
3D Vision System for a Robotic Arm Based on Equal Baseline Camera Array
Authors: Kaczmarek Adam L. 
Published: December 2019

AbstractThis paper presents a lightweight 3D vision system called Equal Baseline Camera Array (EBCA). EBCA can work in different light conditions and it can be applied for measuring large range of distances. The system is a useful alternative to other known distance measuring devices such as structured-light 3D scanners, time-of-flight cameras, Light Detection and Ranging (LIDAR) devices and structure from motion techniques. EBCA can be mounted on a robotic arm without putting significant load on its construction. EBCA consists of a central camera and a ring of side cameras. The system uses stereo matching algorithms to acquire disparity maps and depth maps similarly as in case of using stereo cameras. This paper introduces methods of adapting stereo matching algorithms designed for stereo cameras to EBCA. The paper also presents the analysis of local, semi-global and global stereo matching algorithms in the context of the EBCA usage. Experiments show that, on average, results obtained from EBCA contain 37.49% less errors than the results acquired from a single stereo camera used in the same conditions.

Published: December 2019

AbstractThe Difficulties in Emotion Regulation Scale (DERS) is extensively used as a measure of emotion (dys-)regulation ability in both clinical and nonclinical populations. This is the first study to examine the factor structure of both the original 36-item and short 16-item version of the DERS in adults with eating disorders and to test measurement invariance across diagnostic subgroups. The factor structure of the scale was examined using confirmatory factor analysis in a psychiatric sample of adults with eating disorders (N = 857). Four primary factor structures were fitted to the data: (1) a unidimensional model, (2) a six-factor correlated-traits model, (3) a higher-order factor solution, and (4) a bifactor model. Measurement invariance was tested for diagnostic subgroups of anorexia nervosa and bulimia nervosa and associations between factors and eating pathology were examined in each diagnostic group. Results indicated that a modified bifactor solution fitted the data adequately for both the 36-item and 16-item version of the DERS. A general factor explained most of the variance (86%) and reliability was high for the general factor of DERS (total) but lower for the subscales. Measurement invariance of the bifactor model was supported across diagnostic subgroups and test of factor means reveled that bulimia nervosa had a higher factor mean than anorexia nervosa on the general factor. The general factor accounted for a significant proportion of variance in eating pathology. Our results support the use of the total scale of both the 36-item and 16-item version among adults with eating disorders.
Experimental validation of corrections factors for γ–γ and γ–X coincidence summing of 133Ba, 152Eu, and 125Sb in volume sources
Authors: Jonsson S. , Kastlander J. , Vidmar T. , Ramebäck H. 
Published: December 2019

AbstractTrue coincidence summing correction factors for 133Ba, 152Eu and 125Sb were determined experimentally for a small volume source and compared with correction factors obtained with three softwares (EFFTRAN-X, GESPECOR and VGSL). The radionuclides investigated have a relatively challenging decay scheme and their spectra are known to suffer from losses due to summation (γ–γ, γ–X and X–X) when measured at close distances on a HPGe detector sensitive to low energy photons. This study shows that the softwares were in good agreement with each other and the experimental data and the calculated activity was consistent with the activity in the volume source.
Why Snowden and not Greenwald? On the Accountability of the Press for Unauthorized Disclosures of Classified Information
Authors: Mokrosinska Dorota 
Published: December 2019

AbstractIn 2013, following the leaks by Edward Snowden, The Guardian published a number of classified NSA documents. Both leaking and publishing leaks violate the law prohibiting unauthorized disclosures. Accordingly, there are two potential targets for prosecution: the leakers and the press. In practice, however, only the leakers are prosecuted: Snowden is facing a threat of 30 years’ imprisonment; no charges have been made against The Guardian. If both leaking and publishing leaks violate the law, why prosecute only the leakers and not the press? I consider and reject two arguments. The first claims that the press has special moral claims by virtue of its rights (press freedom) or its role (the Fourth Estate; conduit for information). The second argument states that the leakers commit a greater wrong than the press. I conclude that the current prosecution practice is inconsistent: prosecutors should either prosecute both or neither.
Branching Collision Processes with Immigration

Published: December 2019

AbstractWe consider the regularity and ergodic properties of the Branching Collision Process with Immigration (BCIP) in this paper. We establish an easy checking sufficient condition under which the Feller minimal BCIP is honest. We provide some good conditions under which the Feller minimal BCIP is positive recurrent and then establish an analytic form of the generating function of the stationary distribution. The closely associated expected hitting times are also considered. Examples and numerical calculations are provided to illustrate our results.
Digital camera identification based on analysis of optical defects
Authors: Bernacki Jaroslaw 
Published: December 2019

AbstractIn this paper we deal with the problem of digital camera identification by photographs. Identifying camera is possible by analyzing camera’s sensor artifacts that occur during the process of photo processing. The problem of digital camera identification has been popular for a long time. Recently many effective and robust algorithms for solving this problem have been proposed. However, almost all solutions are based on state-of-the-art algorithm, proposed by Lukás et al. in 2006. Core of this algorithm is to calculate the so-called sensor pattern noise based on denoising images with wavelet-based denoising filter. Such technique is very efficient, but very time consuming. In this paper we consider tracing cameras by analyzing defects of their optical systems, like vignetting and lens distortion. We show that analysis of vignetting defect allows for recognizing brand of the camera. Lens distortion can be used to distinguish images from different cameras. Experimental evaluation was carried out on 60 devices (compact cameras and smartphones) for a total number of 12 051 images, with support of the Dresden Image Database. Proposed methods do not require denoising images with wavelet-based denoising filter what has a significant influence for speed of image processing, compared with state-of-the-art algorithm.
Immersive virtual reality to enforce teaching in engineering education
Authors: Halabi Osama 
Published: December 2019

AbstractPrior studies on the use of digital prototyping and virtual reality (VR) in designing as well as evaluating new products have shown that VR reduces both development time and costs whilst augmenting student motivation and creativity. The current study demonstrates that VR and 3D prototyping in the context of project-based learning (PBL) promote effective communication, increase problem solving skills, and enhance learning outcomes. VR and digital prototyping have been extensively used in industries for the purpose of product design and usability evaluation. In the context of engineering education, many research studies have attempted to explore the effect of VR on teamwork, engagement, retention, and motivation. In this paper, VR is used in conjunction with PBL in self-directed approach to design and implement a product using 3D software whilst also using virtual reality immersive CAVE display to evaluate their design. The hypothesis is that the use of VR with a project-based-learning approach to facilitate the attainment of desirable goals in the engineering design project, improved achievement of course learning outcomes and promoted effective communication. According to the research findings, VR approach significantly affected the distribution of cumulative project grades. Students’ project grades improved, particularly the implementation component. In addition, the course outcomes related to project design were better achieved in VR approach. The communication and problem-solving skills were improved in the VR approach as compared to traditional approach.

Abstract
Purpose
Deficits in neurocognitive functioning (NCF) frequently occur in glioma patients. Both treatment and the tumor itself contribute to these deficits. In order to minimize the harmful effects of surgery, an increasing number of patients undergo awake craniotomy. To investigate whether we can indeed preserve cognitive functioning after state-of-the art awake surgery and to identify factors determining postoperative NCF, we performed a retrospective cohort study.

Methods
In diffuse glioma (WHO grade 2–4) patients undergoing awake craniotomy, we studied neurocognitive functioning both pre-operatively and 3–6 months postoperatively. Evaluation covered five neurocognitive domains. We performed analysis of data on group and individual level and evaluated the value of patient-, tumor- and treatment-related factors for predicting change in NCF, using linear and logistic regression analysis.

Results
We included 168 consecutive patients. Mean NCF-scores of psychomotor speed and visuospatial functioning significantly deteriorated after surgery. The percentage of serious neurocognitive impairments (− 2 standard deviations) increased significantly for psychomotor speed only. Tumor involvement in the left thalamus predicted a postoperative decline in NCF for the domains overall-NCF, executive functioning and psychomotor speed. An IDH-wildtype status predicted decline for overall-NCF and executive functioning.

Conclusions
In all cognitive domains, except for psychomotor speed, cognitive functioning can be preserved after awake surgery. The domain of psychomotor speed seems to be most vulnerable to the effects of surgery and early postoperative therapies. Cognitive performance after glioma surgery is associated with a combination of structural and biomolecular effects from the tumor, including IDH-status and left thalamic involvement.
Self-Efficacy as an Agentic Protective Factor against Death Anxiety in PTSD and Psychiatric Co-Morbidity
Authors: Hoelterhoff Mark , Chung Man Cheung 
Published: December 2019

AbstractPTSD has profound personal, social and economic impact. Understanding factors that influence strong recovery is a priority for informing the use of limited treatment resources. This study follows up a preliminary finding from Hoelterhoff and Cheung Chung, Psychiatr Q, 88, 635-651, [30] which found that death anxiety is related to PTSD and suggested that self-efficacy may mediate this relationship. Specifically, this study examined self-efficacy as a protective factor in the context of people who have experienced a life-threatening event. 109 undergraduate university students completed self-report questionnaires on, self-efficacy, death anxiety, trauma and well-being as well as a number of demographic factors. Self-efficacy was found that to be significantly and inversely related to death anxiety and psychiatric co-morbidity, but not PTSD. Results were discussed in light of literature regarding death anxiety. It seems that self-efficacy is related to death anxiety and well-being; however, it interacts with these processes independently and not as a mediating factor. More research is needed to understand coping mechanisms that help develop resilience against the negative effects of death anxiety against PTSD and minimize its detrimental impact on mental health.
Might Teaching be Judgement Dependent?
Authors: Fisher Andrew , Tallant Jonathan 
Published: December 2019

AbstractOur thesis in this paper is that consideration of Wright’s account of what it is to be judgement-dependent leads us to the conclusion that teaching is judgement dependent. We begin with a consideration of Wright’s account of what it is to be judgement-dependent. We then make the case that teaching satisfies the conditions on what it is to be judgement-dependent. Our intention is not to delve into the independent plausibility of such a view. Our focus is simply on showing the connection between Wright’s account of judgement-dependence and what it is to teach.
