Fathers’ Involvement with Their Children Before and After Separation
Authors: Haux Tina , Platt Lucinda 
Published: July 2020

AbstractChanges in fathering over the last decades have led to substantially more involvement of fathers in their children’s upbringing. At the same time, high rates of parental separation and subsequent loss of contact fuel concern about separated fathers’ role in their children’s lives. Underlying such concern is the assumption that separation represents a discontinuity in fathers’ parenting. This paper investigates whether fathers’ pre- and post-separation paternal involvement is linked: are fathers with lower levels of contact after separation those who were less involved fathers when co-resident? To answer this question, we draw on a nationally representative UK longitudinal study of children born in 2000–2001 to interrogate the links between fathering before and after separation for 2107 fathers, who separated from their child’s mother before the child was age 11. We show that fathers who were more involved parents prior to separation tend to have more frequent contact after separation, adjusting for other paternal and family characteristics. The size of this association between pre- and post-separation fathering is, however, modest, and even among more involved fathers, intensity of contact declines over time.
Of Rebels and Disobedients: Reflections on Arendt, Race, Lawbreaking
Authors: Çubukçu Ayça 
Published: July 2020

AbstractHannah Arendt valued the unprecedented, the unexpected, and the new, yet in essays crafted at the end of the rebellious 1960s, struggled to square this valuation with a palpable desire for law and order. She lamented that criminality had overtaken American life, accused the police of not arresting enough criminals, and charged ‘the Negro community’ with standing behind what she named black violence. At once, she praised ‘the white rebels’ of the student movement in the United States for their courageous acts of disobedience. This essay explores how differential Arendt’s treatment of lawbreaking action was in an effort to understand how ‘certain sections of the population’ in the United States could appear to stand for criminality rather than civil disobedience to her mind. It examines how Arendt’s reflections on the ostensibly non-racial subjects of civil disobedience and lawbreaking were underwritten by racial, when not racist, ways of thinking. The essay also raises a larger question: to the extent that the concept of civil disobedience involves limits, how are those limits drawn to the exclusion of certain kinds of actors and their particular claims in the public realm? Pondering this question through Arendt, it concludes that in her theorization of civil disobedience, Arendt was profoundly limited by the fabulous tale that the United States is an exceptional land of freedom and democracy in the world.
Ferromagnetic core coil hysteresis modeling using fractional derivatives
Authors: Sowa Marcin , Majka Łukasz 
Published: July 2020

AbstractThe modeling of a ferromagnetic core coil magnetic hysteresis has been considered. The measurement basis consisted of waveforms that have been recorded for various levels of the iron core saturation levels. The investigated models included classical cases as well as models including a nonlinear fractional coil. The possibilities of solutions for transient problems including such models have been recalled. The details of the estimation process have been described next, where each model evaluation made use of an original methodology dealing with periodic steady states. The influence of the model response on parameter changes has also been studied. Further on the parameter estimation procedure has been described, and the results for the various models have been presented.
Flugangst aus der Erfahrung von wingwave®-Coaches
Authors: Naumenko Kristina , Niebuhr Frank , Steinhäuser Jost 
Published: July 2020

Zusammenfassung
Hintergrund
Flugangst ist eine häufige, isolierte Phobie. Zu etablierten Therapieformen wie kognitiver Verhaltenstherapie gehören auch Ansätze des „eye movement desensitization and reprocessing“ (EMDR). Das wingwave®-Coaching verwendet die EMDR-Intervention bei Flugangstklienten.

Methode
Mit dem Ziel, Hintergründe zu Flugangst aus der Erfahrung von wingwave®-Coaches zu explorieren, wurden 23 leitfadengestützte Interviews durchgeführt und mittels qualitativer Inhaltsanalyse ausgewertet.

Ergebnisse
Identifizierte Überkategorien waren Gründe, Emotionen als Trigger und Ursachen einer Flugangst. Die Ursachen lagen oft in der Vergangenheit der Betroffenen und waren nicht spontan erinnerlich, da sie häufig keinen direkten Zusammenhang zur Flugangst aufwiesen.

Diskussion
Die etablierten Therapien im Bereich Flugangst berücksichtigen diese Ursachen hinter Flugangst kaum. Zukünftig wäre zu prüfen, ob die Behandlung der Ursachen hinter Flugangst zu länger anhaltenden Erfolgen führt.

Published: July 2020

ZusammenfassungDie vorliegende Studie untersucht die Überzeugungen und die Selbstwirksamkeitserwartungen in Bezug auf kulturelle Diversität von frühpädagogischen Fachkräften. Es wurde (1) untersucht, inwieweit multikulturelle Überzeugungen und diversitätsspezifische Selbstwirksamkeitserwartungen miteinander in Beziehung stehen und sich im zeitlichen Verlauf verändern, und (2) in welchem Zusammenhang die beiden Konstrukte mit der wahrgenommenen Wichtigkeit verschiedener sprachpädagogischer Förderstrategien in Kindertageseinrichtungen stehen. Dazu wurden in einer Längsschnittstudie 251 frühpädagogische Fachkräfte mit spezieller sprachpädagogischer Qualifikation zu zwei Messzeitpunkten befragt. Die Ergebnisse des Strukturgleichungsmodells zeigten, dass multikulturelle Überzeugungen und diversitätsspezifische Selbstwirksamkeitserwartungen in Zusammenhang stehende, aber eigenständige Konstrukte sind, die auf unterschiedliche Weise mit der eingeschätzten Wichtigkeit alltagsintegrierter und additiver Sprachförderansätze in kulturell diversen Gruppen assoziiert sind. So konnte für die multikulturellen Überzeugungen – im Vergleich zu den diversitätsspezifischen Selbstwirksamkeitserwartungen – ein signifikanter Zusammenhang zu der intendierten alltagsintegrierten sprachlichen Förderung festgestellt werden. Die Ergebnisse werden abschließend vor dem Hintergrund ihrer Relevanz für zukünftige Forschung und die Ausbildung frühpädagogischer Fachkräfte diskutiert.

Published: July 2020

AbstractThe manufacturing research has been focusing on the improvement of product performance and lightweight design. The synergic effects between material properties and manufacturing solutions have been considered, extensively. Specifically, joining techniques have been developing with the aim to propose new suitable solutions considering dissimilarities in the properties of the materials that have to be combined. Setting of new manufacturing routes is, therefore, a demanding task. In this direction, there are several methods available in the scientific literature that are focused on sensitivity analysis or optimization/minimization techniques to reduce the necessary attempts or to find a solution/correlation among big data. In this work, the goal of obtaining high joint efficiency between Aluminum and Polycarbonate sheets by the Friction Spot Joining process is considered as a case study. This process must face two main issues, i.e., the mechanical, physical and chemical compatibilities between the parts and the integrity protection of the polymeric sheet near the joining area. The process parameters influences were analysed using numerical simulations performed by a commercial FE code. The number of executed analyses was reduced with a planned DoE. From these results, the Code2Vect algorithm was employed with the aim to visualize, efficiently, high-dimensional data and to evaluate the influences of some identified parameters on the process answer. Finally, a transfer function involving the input and output quantities of interest was derived in a compact representation by a Newton Raphson minimization technique.
International law and human security in a kaleidoscopic world
Authors: Gilder Alexander 
Published: July 2020

AbstractInternational law is being challenged by a multitude of new actors and networks that do not fit within the traditional Westphalian system. Similarly, security is increasingly undermined by, for example, economic, health, and environmental threats that can affect individuals’ daily lives and know no state boundaries. This is the kaleidoscopic world as outlined by Edith Brown Weiss. The concept of ‘human security’ has been advanced to inform decision-making on threats to security in the interest of individuals in a bottom-up manner. This article looks forward to methods that can counter what could be perceived as a legitimacy crisis in international law. First, some of the current challenges which international law faces are explained ranging from globalisation, the declining state-based order, and decentralised security threats. Second, the concept of human security is defined, and its contents expounded. Lastly, the thesis is advanced that a conceptual framework of human security can reorientate international law to be responsive to the kaleidoscopic world by using UN peace operations as an example of where human security could have a profound impact.

Published: July 2020

Introduction The potential efficacy of selected plant extracts to counteract the dermal toxicity of jellyfish envenomation was investigated using an in vitro cell culture model. Methods We studied plant extracts from Carica papaya, Ananas comosus, and Bouvardia ternifolia, known for their antivenom properties, in pairwise combinations with tissue homogenates of the jellyfish Pelagia noctiluca, Phyllorhiza punctata, and Cassiopea andromeda, to evaluate modulations of jellyfish cytotoxic effects. L929 mouse fibroblasts were incubated with pairwise jellyfish/plant extract combinations and examined by MTT assay (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide). Results C papaya and A comosus significantly lowered the cytotoxicity of P noctiluca and P punctata but induced a slight worsening of C andromeda cytotoxicity. Conversely, B ternifolia was protective against P punctata, ineffective against P noctiluca, and worsened C andromeda cytotoxicity. Conclusions Data showed species-specific and contrasting effects of plant extracts, suggesting that those containing protease activities, namely A comosus and C papaya, are more effective in lowering the cytotoxicity of jellyfish venom containing toxic peptidic factors such as phospholipase A. However, all examined plants require further investigation in vivo to evaluate their ability to counteract jellyfish injury to the skin.
COVID-19 Response in Sub-Saharan Africa: Lessons From Uganda
Authors: Lumu Ivan 
Published: July 2020

ABSTRACTThe prolongation of the Ebola epidemic may have allowed some countries to prepare and respond to the coronavirus disease (COVID-19) outbreak. In Uganda, the surveillance structure built for Ebola virus disease (EVD) has become a pillar in the COVID-19 response. This testing and tracing apparatus has limited disease spread to clusters with zero mortality compared with the neighboring East African countries. As more sub-Saharan countries implement social distancing to contain the outbreak, the interventions should be phased and balanced with health risk and socioeconomic situation. However, having a decision-making matrix would better guide the response team. These initial lessons from EVD-experienced Uganda may be helpful to other countries in the region.

AbstractObjective:Methods that include the time-varying nature of healthcare-associated infections (HAIs) avoid biases when estimating increased risk of death and excess length of stay. We determined the excess mortality risk and length of stay associated with HAIs among inpatients in Singapore using a multistate model that accommodates the timing of key events.Design:Analysis of existing prospective cohort study data.Setting:Seven public acute-care hospitals in Singapore.Patients:Inpatients reviewed in a HAI point-prevalence survey (PPS) conducted between June 2015 and February 2016.Methods:We modeled each patient’s admission over time using 4 states: susceptible with no HAI, infected, died, and discharged alive. We estimated the excess mortality risk and length of stay associated with HAIs, with adjustment for the baseline characteristics between the groups for mortality risk.Results:We included 4,428 patients, of whom 469 had ≥1 HAI. Using a multistate model, the expected excess length of stay due to any HAI was 1.68 days (95% confidence interval [CI], 1.15–2.21 days). Surgical site infections were associated with the longest excess length of stay of 4.68 days (95% CI, 2.60–6.76 days). After adjusting for baseline differences, HAIs were associated with increased hazards of in-hospital mortality (adjusted hazard ratio [aHR], 1.32; 95% CI, 1.09–1.65) and decreased hazards in being discharged (aHR, 0.75; 95% CI, 0.67–0.84).Conclusions:HAIs are associated with increased length of hospital stay and mortality in hospitalized patients. Avoiding nosocomial infections can improve patient outcomes and free valuable bed days.
The use of geological, geomorphological and soil mapping products in palaeolandscape reconstructions for the Netherlands
Authors: Pierik Harm Jan , Cohen Kim M. 
Published: July 2020

AbstractGeological, geomorphological and soil maps provide important information on the substrate as well as on the past and present physical landscape. For the intensely studied Netherlands coastal plain and Rhine–Meuse delta, many such map datasets have been compiled over the last two centuries. These mapping materials comprise older and younger legacy datasets, often fragmented over regions. They have been compiled within various research traditions and by various parties, involving geologists, soil scientists, geomorphologists and landscape archaeologists. The maps and datasets summarise overwhelming amounts of underlying data accumulated over the last few centuries, and are therefore valuable for reconstructing past landscapes.Digital-infrastructure developments have enhanced possibilities for recombining existing and new data over the last few decades, e.g. through GIS solutions such as palaeogeographical base maps, from which multiple derived map products can be generated. Integration of thematic information from various source maps and underlying data is needed to use the accumulated data diversity to its full potential and to answer applied and fundamental scientific questions. Using diverse information to compile or update maps, however, requires awareness of legacy surveying strategies and the state of knowledge at the time the original data and maps were produced. This paper reviews the soil, geological and geomorphological mapping traditions. We evaluate their products, underlying data and the reasoning behind their compilation, focusing on their use in conventional and digital palaeogeographical mapping. This helps get the most out of large quantities of legacy and modern data, a major challenge for surface and substrate digital mapping in the big-data era.

Published: July 2020

AbstractMassive, early-type stars have been detected as radio sources for many decades. Their thermal winds radiate free–free continuum and in binary systems hosting a colliding-wind region, non-thermal emission has also been detected. To date, the most abundant data have been collected from frequencies higher than 1 GHz. We present here the results obtained from observations at 325 and 610 MHz, carried out with the Giant Metrewave Radio Telescope, of all known Wolf-Rayet and O-type stars encompassed in area of$\sim$15 sq degrees centred on the Cygnus region. We report on the detection of 11 massive stars, including both Wolf-Rayet and O-type systems. The measured flux densities at decimeter wavelengths allowed us to study the radio spectrum of the binary systems and to propose a consistent interpretation in terms of physical processes affecting the wide-band radio emission from these objects. WR 140 was detected at 610 MHz, but not at 325 MHz, very likely because of the strong impact of free–free absorption (FFA). We also report—for the first time—on the detection of a colliding-wind binary system down to 150 MHz, pertaining to the system of WR 146, making use of complementary information extracted from the Tata Institute of Fundamental Research GMRT Sky Survey. Its spectral energy distribution clearly shows the turnover at a frequency of about 600 MHz, that we interpret to be due to FFA. Finally, we report on the identification of two additional particle-accelerating colliding-wind binaries, namely Cyg OB2 12 and ALS 15108 AB.
What You See Is Not Always What You Get: Bargaining before an Audience under Multiparty Government
Authors: MARTIN LANNY W. , VANBERG GEORG 
Published: July 2020

AbstractParty elites in coalition governments are acutely aware that the deals they strike will be critically evaluated by their supporters, and that they risk losing support if they are perceived as ineffective negotiators. This has a powerful influence on the bargains parties strike. Because most supporters are unaware of the complex aspects of bargains and instead rely on simple heuristics to evaluate their most visible features, parties have incentives to meet supporter expectations primarily on easily observable outcomes. To do so, they make trade-offs on less observable outcomes. This implies that the more visible features of a bargain typically do not accurately reflect the relative success of parties in coalition negotiations. We evaluate our argument using original data on the office rewards and policy risks of portfolio allocation in 16 parliamentary democracies. Our findings support our argument, and they have important implications for the nature of representation under multiparty government.
Assessing the Positioning Performance Under the Effects of Strong Ionospheric Anomalies With Multi‐GNSS in Hong Kong
Authors: Lu Yangwei , Wang Zhenjie , Ji Shengyue , Chen Wu 
Published: July 2020

AbstractGlobal navigation satellite system (GNSS) precise positioning performance will be strongly affected under severe ionospheric anomaly conditions. The combination of multi‐GNSS can increase the available observations and improve the geometry of continuously tracked satellites. This paper focuses on assessing the positioning performance with the combination of Global Positioning System (GPS), Global'naya Navigatsionnaya Sputnikova Sistema (GLONASS), and BeiDou System (BDS) around the St. Patrick's Day geomagnetic storm (9–18 March) in 2015 in Hong Kong. The rate of total electron content (TEC) index (ROTI) indicates severe ionospheric anomalies before the superstorm, while it was absent during the main phase of the storm in Hong Kong. Furthermore, strong scintillation events on signal‐to‐noise ratio (SNR) and multipath (MP) observables are observed during ionospheric anomalies period. Then the performance of single‐point positioning (SPP) and precise point positioning (PPP) with multi‐GNSS is shown. The ionospheric scintillation events may reduce pseudorange accuracy but affect SPP performance a little in this study, while the PPP accuracy is vastly decreased due to the subsequent reconvergence caused by frequent cycle slip (CS). Compared to PPP solutions with GPS only, the accuracy is improved significantly with the combination of multi‐GNSS.
Soil and Air Temperature Calibrations Using Branched GDGTs for the Tropical Andes of Colombia: Toward a Pan‐Tropical Calibration

Published: July 2020

AbstractBranched glycerol dialkyl glycerol tetraethers (brGDGTs) are bacterial cell membrane lipids that, when preserved in sedimentary archives, can be used to infer continental paleotemperatures. Although commonly used global calibrations capture a relationship between the distribution of brGDGTs and temperature, they underestimate temperatures for tropical regions as much as ~16°C. Furthermore, some global calibrations reach saturation at around 24–25°C, and, in general, they have root‐mean‐squared errors (RMSEs ≈ ~4°C) that are too large for them to resolve small variations in paleoclimate variability in tropical regions. We present an in situ regional calibration of soil brGDGTs along altitudinal transects on both flanks of the Eastern Cordillera of Colombia in the northern tropical Andes that spans ~3,200 m in elevation and 17°C and 19°C in mean annual soil and air temperatures, respectively. These new soil and air regional calibrations yield RMSEs of 1.5°C and 1.9°C, respectively. When combined with existing data from elsewhere in the tropics, the integrated data (n = 175) not only fit a linear calibration with a RMSE of 2.7°C but also fit a nonlinear calibration with a RMSE of 2.2°C. These calibrations allow for a more precise and reliable reconstruction of past temperatures in the tropics than global calibrations.
Leveraging large genomic datasets to illuminate the pathobiology of autism spectrum disorders
Authors: Searles Quick Veronica B. , Wang Belinda , State Matthew W. 
Published: July 2020

Abstract“Big data” approaches in the form of large-scale human genomic studies have led to striking advances in autism spectrum disorder (ASD) genetics. Similar to many other psychiatric syndromes, advances in genotyping technology, allowing for inexpensive genome-wide assays, has confirmed the contribution of polygenic inheritance involving common alleles of small effect, a handful of which have now been definitively identified. However, the past decade of gene discovery in ASD has been most notable for the application, in large family-based cohorts, of high-density microarray studies of submicroscopic chromosomal structure as well as high-throughput DNA sequencing—leading to the identification of an increasingly long list of risk regions and genes disrupted by rare, de novo germline mutations of large effect. This genomic architecture offers particular advantages for the illumination of biological mechanisms but also presents distinctive challenges. While the tremendous locus heterogeneity and functional pleiotropy associated with the more than 100 identified ASD-risk genes and regions is daunting, a growing armamentarium of comprehensive, large, foundational -omics databases, across species and capturing developmental trajectories, are increasingly contributing to a deeper understanding of ASD pathology.
