Global Climate Implications for Homelessness: A Scoping Review
Authors: Kidd Sean A. , Greco Susan , McKenzie Kwame 
Published: September 2020

AbstractHomelessness is a persistent global challenge with significant health impacts on those affected. Homeless people are by definition the most exposed to weather conditions and the social and economic problems caused by extreme weather and climate change and variability. This systematic review was designed to synthesize the academic literature that addresses the health and social implications of global climate change for homelessness. The question examined in this systematic scoping review is the following: What is the current state of knowledge in the scientific literature on the health and social implications of global climate change for homelessness? A systematic scoping review method was used to identify and synthesize the peer-reviewed literature relevant to this question. The databases searched were PsycINFO, Medline, Scopus, and Google Scholar. Of the 26 papers identified in this review, 20 employed original data analyses with conclusions largely inferred from cross-sectional associations. Themes included the potential influence of climate change on homelessness prevalence, climate impacts that exacerbate specific vulnerabilities of homeless populations (e.g., chronic illness, exposure, stigmatization), and health and social outcomes. Service use and design implications were also addressed. Given the scale of the impacts of climate change on homelessness, the literature on this topic poses promising directions but is under-developed in its current state to adequately inform risk mitigation and response planning. A systems framework is proposed here to inform future research and service design.

AbstractThe investigation is dedicated to the detailed microstructure characterization of explosively welded clads, in which, exceptionally and for cognitive purposes, a very high detonation speed of about 2800 m/s was used to manufacture bimetallic aluminum-nickel plates. The study involves detailed microstructural characteristics of the bonded zone at micro and nano level, especially focused on the expanded melted regions consisted mostly of Al3Ni, Al3Ni2 and AlNi phases. In situ heating experiment in transmission electron microscope allowed observing microstructure transformation revealing that additionally present metastable Al9Ni2 phase was transformed to Al3Ni and Al3Ni2. Microhardness measurements across the welded zone showed the increase of the microhardness of nickel alloy plate from 153 up to 170 HV when approaching to the Ni201/A1050 interface, while the value for aluminum plate was of 45 HV. Within the melted zones the microhardness was found to be 135 HV and it enormously increased to 850 HV after annealing of the sample at 500 °C. This change was due to the transformation of the interface region from the waves with the melted zones into the continuous layers of two intermetallic phases: Al3Ni and Al3Ni2. The second phase grew at the expense of the Al3Ni.

Rüstungspolitik im Zeichen des Versagens: Die Trendwende Material der Bundeswehr zwischen Anspruch und Realität
Authors: Sebaldt Martin 
Published: September 2020

ZusammenfassungDie deutsche Rüstungspolitik versagt: Seit einigen Jahren steht sie unter dem Motto Trendwende Material, und trotzdem ist es ihr nicht gelungen, die prekäre Ausstattungslage der Bundeswehr signifikant zu verbessern. Eine Auseinandersetzung mit den zentralen militärpolitischen Planungsdokumenten der letzten Jahre (Verteidigungsweißbuch, Konzeption der Bundeswehr, Strategie der Reserve) enthüllt den entscheidenden Grund dieses Versagens: strategisch-konzeptionelles Unvermögen. Folgerung: Nur eine grundlegende Erneuerung militärpolitischer Strategiearbeit kann dieses rüstungspolitische Unvermögen beheben.
Managing randomization in the multi-block alternating direction method of multipliers for quadratic optimization
Authors: Mihić Krešimir , Zhu Mingxi , Ye Yinyu 
Published: September 2020

AbstractThe Alternating Direction Method of Multipliers (ADMM) has gained a lot of attention for solving large-scale and objective-separable constrained optimization. However, the two-block variable structure of the ADMM still limits the practical computational efficiency of the method, because one big matrix factorization is needed at least once even for linear and convex quadratic programming. This drawback may be overcome by enforcing a multi-block structure of the decision variables in the original optimization problem. Unfortunately, the multi-block ADMM, with more than two blocks, is not guaranteed to be convergent. On the other hand, two positive developments have been made: first, if in each cyclic loop one randomly permutes the updating order of the multiple blocks, then the method converges in expectation for solving any system of linear equations with any number of blocks. Secondly, such a randomly permuted ADMM also works for equality-constrained convex quadratic programming even when the objective function is not separable. The goal of this paper is twofold. First, we add more randomness into the ADMM by developing a randomly assembled cyclic ADMM (RAC-ADMM) where the decision variables in each block are randomly assembled. We discuss the theoretical properties of RAC-ADMM and show when random assembling helps and when it hurts, and develop a criterion to guarantee that it converges almost surely. Secondly, using the theoretical guidance on RAC-ADMM, we conduct multiple numerical tests on solving both randomly generated and large-scale benchmark quadratic optimization problems, which include continuous, and binary graph-partition and quadratic assignment, and selected machine learning problems. Our numerical tests show that the RAC-ADMM, with a variable-grouping strategy, could significantly improve the computation efficiency on solving most quadratic optimization problems.

Published: September 2020

AbstractThe new definition of the kilogram was implemented on May 20, 2019. The kilogram is presently defined by a fixed value of the Planck constant. On the basis of the new definition, the kilogram will be realized at the National Metrology Institute of Japan by the X-ray crystal density method using 28Si-enriched spheres. For the realization, the volume of 28Si-enriched spheres is measured by optical interferometry. The sphere surface characterization by X-ray photoelectron spectroscopy and ellipsometry is also performed. The relative standard uncertainty of the realization is estimated to be 2.4 × 10−8. Details of the realization and future dissemination of mass standards in Japan based on the 28Si-enriched spheres are described.
Development of D-Loop mitochondrial markers for amplification of prey DNA from wolf scat
Authors: Schroeder Hilke , Palczewski Stefanie , Degen Bernd 
Published: September 2020

AbstractAnalysis of wolves dietary is a currently important theme because of the discussion about wolves preying on livestock as sheep or goats. We developed molecular markers to especially amplify the DNA of the prey out of wolf scat. For this purpose, we used the mitochondrial D-Loop using public available sequences for wolf and seven potential prey species (even-toed ungulates). We developed special primers amplifying either the wolves DNA or the prey DNA. In a fragment of 223-225 basepairs (bp) length we identified 21 SNPs, two 1-bp indels and one 3-bp indel, and three microsatellites to separate seven prey species from each other. Validation of the markers was performed by sequencing the PCR products of 12 fresh prey tissues and 20 wolf scat samples using the different primer pairs.

AbstractIn the context of (digital) human–machine interaction, people are increasingly dealing with artificial intelligence in everyday life. Through this, we observe humans who embrace technological advances with a positive attitude. Others, however, are particularly sceptical and claim to foresee substantial problems arising from such uses of technology. The aim of the present study was to introduce a short measure to assess the Attitude Towards Artificial Intelligence (ATAI scale) in the German, Chinese, and English languages. Participants from Germany (N = 461; 345 females), China (N = 413; 145 females), and the UK (N = 84; 65 females) completed the ATAI scale, for which the factorial structure was tested and compared between the samples. Participants from Germany and China were additionally asked about their willingness to interact with/use self-driving cars, Siri, Alexa, the social robot Pepper, and the humanoid robot Erica, which are representatives of popular artificial intelligence products. The results showed that the five-item ATAI scale comprises two negatively associated factors assessing (1) acceptance and (2) fear of artificial intelligence. The factor structure was found to be similar across the German, Chinese, and UK samples. Additionally, the ATAI scale was validated, as the items on the willingness to use specific artificial intelligence products were positively associated with the ATAI Acceptance scale and negatively with the ATAI Fear scale, in both the German and Chinese samples. In conclusion we introduce a short, reliable, and valid measure on the attitude towards artificial intelligence in German, Chinese, and English language.

Published: September 2020

AbstractWhite lupin (Lupinus albus L.) is a high-protein grain legume crop, grown since ancient Greece and Rome. Despite long domestication history, its cultivation remains limited, partly because of susceptibility to anthracnose. Only some late-flowering, bitter, low-yielding landraces from Ethiopian mountains displayed resistance to this devastating disease. The resistance is controlled by various genes, thereby complicating the breeding efforts. The objective of this study was developing tools for molecular tracking of Ethiopian resistance genes based on genotyping-by-sequencing (GBS) data, envisaging linkage mapping and genomic selection approaches. Twenty GBS markers from two major quantitative trait loci (QTLs), antr04_1/antr05_1 and antr04_2/antr05_2, were converted to PCR-based markers using assigned transcriptome sequences. Newly developed markers improved mapping resolution around both anthracnose resistance loci, providing more precise QTL estimation. PCR-based screening of diversified domesticated and primitive germplasm revealed the high specificity of two markers for the antr04_1/antr05_1 locus (TP222136 and TP47110) and one for the antr04_2/antr05_2 locus (TP338761), highlighted by simple matching coefficients of 0.96 and 0.89, respectively. Moreover, a genomic selection approach based on GBS data of a recombinant inbred line mapping population was assessed, providing an average predictive ability of 0.56. These tools can be used for preselection of candidate white lupin germplasm for anthracnose resistance assays.
Conditional Accountability for the Economy, Insecurity, and Corruption Across Latin American Party Systems
Authors: Singer Matthew M. 
Published: September 2020

ABSTRACTThe association between how citizens perceive economic performance, insecurity, or corruption and how they evaluate the president varies systematically across Latin American countries and within them over time. In particular, while presidential popularity reflects these outcomes in the average Latin American country, survey data from 2006–17 confirm that the connection between government performance and presidential approval is generally stronger when unfragmented party systems or single-party majority governments make assessments of political responsibility easier. While these results suggest that the region’s citizens do not blindly blame the president for outcomes where political responsibility should be shared, they also remind us that there are many countries in the region where fragmented party systems weaken the conditions for effective political accountability.
‘Cyclone Not Above Politics’ : East Pakistan, disaster politics, and the 1970 Bhola Cyclone
Authors: BISWAS SRAVANI , DALY PATRICK 
Published: September 2020

AbstractOn 12 November 1970, the Bhola Cyclone swept across the southern districts of East Pakistan, killing over 300,000 people. Small islands were swept away and dead bodies of humans and cattle lay strewn across the devastated landscape. Following the news of the destruction, journalists, students, artists, and political workers rushed to the affected area with basic relief supplies, without waiting for the Military Law Administration (MLA) to intervene. The cyclone's occurrence just three weeks prior to the first general elections in Pakistan added a new dimension to the already simmering political crisis. The extensive media coverage of the disaster brought the pitiful state of infrastructural development and lack of governance in East Pakistan under local and global scrutiny. The cyclone and the corresponding issues soon became embroiled within the larger political demand for regional autonomy. The MLA came under attack from sections of East Pakistan's politicians, press, and public, as well as international political actors, for its poor disaster governance. This article uses the Bhola Cyclone of 1970 as the lens to explore the complex interconnections between environmental disasters and a key issue of governance. While the Bhola Cyclone has been a subject of recent discussions, this article uses a disaster-politics analytical framework to understand the disaster's role in the subsequent political turbulence and the emergence of Bangladesh.

AbstractBackgroundDespite a growing understanding of disorders of consciousness following severe brain injury, the association between long-term impairment of consciousness, spontaneous brain oscillations, and underlying subcortical damage, and the ability of such information to aid patient diagnosis, remains incomplete.MethodsCross-sectional observational sample of 116 patients with a disorder of consciousness secondary to brain injury, collected prospectively at a tertiary center between 2011 and 2013. Multimodal analyses relating clinical measures of impairment, electroencephalographic measures of spontaneous brain activity, and magnetic resonance imaging data of subcortical atrophy were conducted in 2018.ResultsIn the final analyzed sample of 61 patients, systematic associations were found between electroencephalographic power spectra and subcortical damage. Specifically, the ratio of beta-to-delta relative power was negatively associated with greater atrophy in regions of the bilateral thalamus and globus pallidus (both left>right) previously shown to be preferentially atrophied in chronic disorders of consciousness. Power spectrum total density was also negatively associated with widespread atrophy in regions of the left globus pallidus, right caudate, and in the brainstem. Furthermore, we showed that the combination of demographics, encephalographic, and imaging data in an analytic framework can be employed to aid behavioral diagnosis.ConclusionsThese results ground, for the first time, electroencephalographic presentation detected with routine clinical techniques in the underlying brain pathology of disorders of consciousness and demonstrate how multimodal combination of clinical, electroencephalographic, and imaging data can be employed in potentially mitigating the high rates of misdiagnosis typical of this patient cohort.
What drives partisan conflict and consensus on welfare state issues?
Authors: Ennser-Jedenastik Laurenz 
Published: September 2020

AbstractLeft-right partisan conflict has been a key driver of welfare state expansion and retrenchment over time and across countries. Yet, we know very little about how left-right differences in party appeals vary across social policy domains. Why are some issues contentious while there is broad consensus on others? This paper starts from the simple premise that partisan conflict is a function of how popular a certain policy is. Based on this assumption, it argues that the left-right gap should be (1) larger for revenue-side issues than for expenditure-side issues, (2) larger for policies targeted at groups that are viewed as less deserving and (3) larger for more redistributive programs than less redistributive ones (e.g. means-tested versus earnings-related benefits). These expectations are tested on fine-grained policy data coded from 65 Austrian party manifestos issued between 1970 and 2017 (N = 18,219). The analysis strongly supports the revenue–expenditure hypothesis and the deservingness hypothesis, but not the redistribution hypothesis.

AbstractAim:To compare the dosimetry and reproducibility of set-up with monoisocentric technique (MIT) and dual isocentric technique (DIT) in adjuvant breast radiotherapy (RT).Material and methods:Breast cancer patients treated with MIT or DIT were retrospectively studied. The organ-at-risk dose was compared between two groups. All patients underwent set-up verification with an electronic portal imaging device, and set-up time was recorded for each fraction. Treatment reproducibility was assessed in terms of systematic and random error.Results:Twenty patients were included (11 right and 9 left-sided tumours) and ten received whole breast RT, while the rest received chest wall RT. Overall, the mean heart dose was less with MIT (0.40 versus 0.79, p = <0.001) as well as in left-sided tumours (0.37 versus 0.98, p = 0.003). The maximum dose at the field junction was significantly higher with DIT (43 Gy, 107%, p = 0.003). The maximum total error was 1 cm in lateral for supraclavicular field and 8 mm in superior–inferior in tangents for both techniques. There was no difference in set-up errors between the two techniques.Findings:MIT resulted in better dose homogeneity at the field junctions and reduced mean heart dose as compared to DIT. MIT is safe for implementation in clinical practice for breast cancer treatment.Conclusion:This study is one of the few studies comparing MIT with DIT in terms of the dosimetry and the first one to compare set-up errors between the two techniques. The ease of set-up and better dosimetry with MIT was achieved.

AbstractRice (Oryza sativa L.) is the primary staple crop in Taiwan, and it can be grown twice a year. The prevalent subspecies grown in Taiwan is Japonica, and a transplanting system is used for rice production. Although the transplanting system is known for efficient weed control at the seedling stage, weedy red rice (WRR, O. sativa f. spontanea) infestation is progressively being reported. Fieldwork and previous studies have suggested that WRR infestation in Taiwan is probably related to growers’ operating practices and their perception of WRR. However, no data are available for a detailed investigation. The present study aimed to collect data on rice growers’ backgrounds, farming practices, and perceptions of WRR to quantify and characterize the patterns of farming operations for rice growers in Taiwan and to investigate factors contributing to WRR infestation. We collected 408 questionnaires completed by rice growers from 17 counties covering all rice production regions in Taiwan. The growers’ median age was 51 to 60 yr, and 75% of respondents had paddies from 0.25 to 2.75 ha in size, which corresponded with nationwide data for farmers’ backgrounds. In general, growers applied similar farming practices for both cropping seasons. Most respondents did not notice WRR infestation or consider it to be a problem: only 9.8% noticed a moderate to severe infestation of WRR in their fields. The major perceived causes of WRR infestation was seed impurity (55.1%) or cultivar degeneration (18.6%). Correlation analysis and farming patterns estimated with a nonnegative matrix factorization algorithm showed that WRR contamination rate was due to the use of dry or wet tillage. The present study provides the first quantitative and qualitative evidence of rice production practices and growers’ perceptions of WRR infestation in Taiwan.
Wave Equation‐Based Local Traveltime Inversion
Authors: Hu Y. , Han L. G. , Liu Y. S. , Jin Z. Y. 
Published: September 2020

AbstractFull waveform inversion (FWI) is a strongly nonlinear optimization problem, which suffers from cycle skipping when the initial velocity model is not good enough or the seismic data lack low frequencies. Traveltime tomography is often used to invert the low‐wave number components of a velocity model, but traveltime inversion results show a low‐resolution model. To bridge the inversion wave number gap between the traveltime tomography and the FWI, a wave equation‐based local travetime inversion is proposed. In this case, the cross‐correlation algorithm is applied to calculate the traveltime differences between the localized synthetic and observed data. To mitigate traveltime crosstalk noise caused by multiple seismic events, a sliding Gaussian window is applied to transform the seismic data into local domain. In this way, the traveltime information of different seismic events can be simultaneously used to improve the inversion results. The numerical examples show that the combination of Local Traveltime Inversion (LTI) and FWI successfully mitigate the cycle skipping and produce satisfactory inversion results, even if the seismic data lack low frequencies and the initial velocity model is far from the true one.
