Abstract
Peste des petits ruminants (PPR) is a highly contagious and acute viral disease of small ruminants. Occasionally, PPR can affect wildlife with devastating results, such as the recent outbreaks in Mongolian saiga. The yak (Bos grunniens and Bos mutus) is a large ruminant found throughout the Himalayan region of south Central Asia, the Tibetan Plateau and as far north as Mongolia and Russia. In Pakistan, yaks are confined to the high plateau of the Northern Areas, from Gilgit to the valley of Ladakh. In Tajikistan, yaks are present in districts in the north, east and southeast of the country. Commonly, yak intermingle with domestic animals during winter when mountainous summer pastures are covered with snow, and with wildlife during summer pastures. PPR is considered endemic in sheep and goats in Pakistan and Tajikistan. In this study, we investigated the potential presence of antibodies to peste-des-petits-ruminants virus (PPRV) in yak populations using ELISA. A total of 250 (Pakistan) and 85 (Tajikistan) serum samples of healthy yaks were collected. None of the Tajik yaks were seropositive (95% confidence interval (CI) 0.0–4.2%), while 23 of 250 (9.2%; 95% CI 5.9–13.5%) yaks sampled in Pakistan were found positive. Whether PPRV is continuously circulating among yaks or seroconversion reflects spill-over from outbreaks of PPR in domestic animals remains unknown. Due to the herding practices, yak might transmit PPR from domestic to wild ruminants. Differences in contacts between yaks and domestic animals in Pakistan and Tajikistan, or the low sample size, could explain that no Tajik yaks were seropositive.
Breaking Free: One Adolescent Woman’s Recovery from Dating Violence Through Creative Dance
Authors: Margolin Indrani 
Published: November 2019

Abstract
Dating violence against adolescent women can devastate their health and long-term quality of life. While high school programs have been developed to address this worldwide epidemic, somatic antidotes are still not widely utilized despite evidence from the psychophysiology of relational violence trauma that there is an inextricable link between the body and mind and effective recovery requires a holistic approach. Creative dance, derived from dance education, can support female adolescent trauma victims of dating violence to reconnect with physical, mental, and emotional experiences that were severed during traumatic exposure. This qualitative arts-based case study narratively explores one adolescent woman’s experience of creative dance as an intervention for survivors of dating violent relationships. Conceptually, I draw from dance education, Authentic Movement, and Amber Gray’s Restorative Movement Psychotherapy. A feminist lens is utilized in an attempt to address calls to action from previous DMT researchers to tackle oppressive structural forces and increase activism in dance/movement therapy. Findings show that inner-directed dance can therapeutically facilitate restoration after trauma by recovering the social engagement system and decision-making capacity, reducing social isolation, and increasing bodily self-awareness, and self-esteem.

AbstractTilapia hatcheries in Tanzania rely heavily on importing germplasm. Nevertheless, the genetic structure of the imported stocks is poorly understood. In the current study, the level of genetic diversity and differentiation of eight populations of Nile tilapia (Oreochromis niloticus) strains imported in Tanzania was investigated. Four of the studied strains originated from Thailand, three from Uganda, and one from the Netherlands. Double-digest restriction site–associated DNA sequencing (ddRAD-seq) was applied to identify and genotype single nucleotide polymorphisms (SNPs). In total, 2214 SNPs passed all the quality control steps and were utilized for downstream analysis. Mean heterozygosity estimates were higher for the Thailand strains (Ho, 0.23) compared with the strains from Uganda (Ho, 0.12). Low genetic distance was observed amongst populations from the same geographic origin (Fst, 0.01–0.04). However, genetic distance between populations from different geographic origins was substantial (Fst, 0.24–0.44). Bayesian model–based clustering (STRUCTURE) and discriminant analysis of principal components (DAPC) grouped the studied animals into three distinct clusters. A cross-validation approach (where 25% of animals from each population were considered of unknown origin) was conducted in order to test the efficiency of the SNP dataset for identifying the population of origin. The cross-validation procedure was repeated 10 times resulting in approximately 97% of the tested animals being allocated to the correct geographic population of origin. The breeding history and hatchery practices used to manage these stocks prior and after import appear to be the main factors for the genetic diversity observed in this study. Our study will help inform hatchery stock management and future breeding program designs in Tanzania.
The CO2/CO32−chemistry of the NaOH(aq) model system applicable to cellulose solutions

Published: November 2019

AbstractMolecular interactions governing the recently reported CO2/CO32−chemistry of cellulose/NaOH(aq) solutions are investigated using a cellulose analogue methyl-β-D-glucopyranoside in NaOH(aq) solutions under conditions feasible with cellulose dissolution.1H,13C and steady-state heteronuclear Overhauser effect NMR spectroscopy complemented by pH measurements reveal carbohydrate–CO32−interactions as an important component of this chemistry. However, depending on in which order carbohydrate and CO32−are brought together in NaOH(aq) this interaction is different with different implications on stability of the CO32−in the solution.
Female Labor Market Participation Across Cohorts: Evidence from the Netherlands
Authors: Nientker Wouter , Alessie Rob 
Published: November 2019

Abstract
This study investigates female labor force participation in the Netherlands between 1985 and 2014 and proposes a new approach to address the age–period–cohort identification problem. The prime working age model assumes a constant effect of age on female labor force participation for women who are at least 45 years old but younger than 50. This model generates plausible predictions of the age-, period- and cohort profiles of female labor participation. Those predictions are very similar to the ones obtained by using the intrinsic estimator approach of Yang et al. (Sociol Methodol 34(1):75–110, 2004).
Children with Behavioural Problems Misinterpret the Emotions and Intentions of Others

Published: November 2019

Abstract
Research indicates that the misinterpretation of other’s emotions or intentions may lead to antisocial behaviour. This study investigated emotion and intention recognition in children with behavioural problems and examined their relationship and relations with behaviour problem severity. Participants were 7–11 year old children with behavioural problems (n = 93, mean age: 8.78, 82.8% male) who were taking part in an early intervention program and typically developing controls (n = 44, mean age: 9.82, 79.5% male). Participants completed emotion recognition and Theory of Mind tasks. Teachers and parents rated children’s emotional and behavioural problems. Children with behavioural problems showed impaired emotion and intention recognition. Emotion recognition and intention recognition were positively related and inversely associated with behavioural problem severity and, independently of one another, predicted behavioural problems. This study is the first to show that children with behavioural problems are impaired in identifying others’ emotions as well as intentions. These social cognitive processes were found to be related and inversely associated with severity of behavioural problems. This has important implications for intervention and prevention programmes for children with behavioural difficulties.

Published: November 2019

Abstract
Silicone/phosphor composite, which serve as mechanical protection and light conversion material, is an integral part of white light-emitting diode (LED) package. In this paper, a comprehensive study is conducted to investigate the effect of humidity and phosphor on moisture absorption, hygroscopic swelling, mechanical behavior, as well as thermal properties of silicone/phosphor composite in comparison with the pure silicone. SEM/EDAX and FTIR were performed to identify the phosphor and silicone compositions. Through moisture sorption test, it has been observed that the addition of phosphor significantly lowers the capacity of moisture absorption, but accelerates the diffusivity of moisture absorption. The hygroscopic swelling test showed that the phosphor has little effect on the swelling compared to the pure silicone sample. Both moisture absorption/desorption and hygroscopic swelling/de-swelling are reversible. Strain ramp test revealed that the phosphor enhances the stiffness of the composite. The moisture absorption, however, has negligible impact on mechanical stiffness for both pure and composite samples. Finally, thermal expansion test showed that the coefficient of thermal expansion does not change with the addition of phosphor into pure silicone.

Abstract
Concentrations of 129I in coastal surface sediment samples from the east coast of Aomori, Japan, 2–65 km away from the wastewater outlet of the nuclear fuel reprocessing plant at Rokkasho, Japan, were measured from 2006 to 2010. No clear effect on 129I/127I atom ratios in marine sediments was observed, although 129I was discharged from the plant, during its test operation using actual spent fuel, mainly between 2006 and 2008. The ratio in sediments collected at a fishing port at the mouth of a brackish lake increased in 2007, showing that the 129I migrated from the lake to the port.
How to tell a happy person: Accuracy of subjective well-being perception from texts
Authors: Stavrova Olga , Haarmann Lena 
Published: November 2019

AbstractAlthough perceptions of subjective well-being (SWB) in unacquainted others have been shown to play a major role in impression formation, little is known about how accurate such perceptions are. In two original studies and one pre-registered replication, we explored the accuracy of life satisfaction and happiness judgments from texts and its underlying mechanisms (use of linguistic cues). Participants filled in life satisfaction and happiness measures and completed a brief writing task. Another sample of participants judged the targets’ life satisfaction and happiness from the obtained texts. All three studies demonstrated a small to moderate self-other agreement. A linguistic analysis showed that targets with higher (vs. lower) scores on SWB were less likely to use negation words in their texts, which allowed observers to make accurate judgment of their SWB level. Two studies pointed at negative emotion words as valid and positive emotion words as invalid (but often used) cues to happiness, yet these effects did not replicate in Study 3.
Ambiguity and price competition
Authors: Routledge R. R. , Edwards R. A. 
Published: November 2019

Abstract
There are few models of price competition in a homogeneous-good market which permit general asymmetries of information amongst the sellers. This work studies a price game with discontinuous payoffs in which both costs and market demand are ex ante uncertain. The sellers evaluate uncertain profits with maximin expected utilities exhibiting ambiguity aversion. The buyers in the market are permitted to split between sellers tieing at the minimum price in arbitrary ways which may be deterministic or random. The role of the primitives in determining equilibrium prices in the market is analyzed in detail.

Published: November 2019

Abstract
The aim of the study was to evaluate the influence of the application of increasing proportions (0%, 10%, 25%, 50%, 75%, and 100%) of an admixture of PCB-contaminated Hudson River sediment collected from the Upper Hudson River, near Waterford, Saratoga county (New York, USA) on soil properties, phytotoxicity, and biometric and physiological responses of cucumber (Cucumis sativus L. cv ‘Wisconsin SMR 58’) and zucchini (Cucurbita pepo L. cv ‘Black Beauty’) grown as potential phyto- and rhizoremediators. The experiment was performed for 4 weeks in a growth chamber under controlled conditions. Amendment of Hudson River sediment to soil led to a gradual increase in PCB content of the substratum from 13.7 μg/kg (with 10% sediment) to 255 μg/kg (with 100% sediment). Sediment amendment showed no phytotoxic effects during the initial stages, even Lepidium sativum root growth was stimulated; however, this positive response diminished following a 4-week growth period, with the greatest inhibition observed in unplanted soil and zucchini-planted soil. The stimulatory effect remained high for cucumber treatments. The sediment admixture also increased cucurbit fresh biomass as compared to control samples, especially at lower doses of sediment admixture, even though PCB content of the soil amended with sediment increased. Cucurbits’ leaf surface area, in turn, demonstrated an increase for zucchini, however only for 50% and 75% sediment admixture, while cucumber showed no changes when lower doses were applied and decrease for 75% and 100% sediment admixture. Chlorophyll a + b decreased significantly in sediment-amended soils, with greater inhibition observed for cucumber than zucchini. Our results suggest that admixture of riverine sediment from relatively less-contaminated locations may be used as soil amendments under controlled conditions; however, further detailed investigation on the fate of pollutants is required, especially in terms of the bioaccumulation and biomagnification properties of PCBs, before contaminated sediment can be applied in an open environment.

Price and Condition Parity Clauses in Contracts Between Hotel Booking Platforms and Hotels
Authors: Mackenrodt Mark-Oliver 
Published: November 2019

Abstract
Price parity clauses on digital platforms, such as hotel booking platforms, have been the subject of divergent decisions under Art. 101 TFEU by courts and competition authorities in many EU Member States. These decisions have revealed significant differences between and even within single Member States with regard to the dogmatic treatment of price parity clauses, the factual assessment and the legal outcome. Some countries have even introduced special legislation with regard to price parity clauses. The Swedish Patent and Market Court of Appeals in May 2019 declared narrow price parity clauses to be consistent with Art. 101 TFEU. Only a few weeks later the German Düsseldorf Court of Appeals (Oberlandesgericht, OLG) overturned a decision by the German Competition Authority (Bundeskartellamt) and also held that narrow price parity clauses are valid. This case is on appeal to the German Supreme Court (Bundesgerichtshof). However, the judgments by the two courts of appeals are at odds with regard to their dogmatic approach to Art. 101 TFEU and to the factual findings. Against this background, the Swedish court of appeals’ judgment casts light on several aspects that might be of relevance for similar cases in other jurisdictions or that require clarification by a referral to the ECJ or by the lawmakers.
Leveraging Domain Context for Question Answering Over Knowledge Graph
Authors: Tong Peihao , Zhang Qifan , Yao Junjie 
Published: November 2019

AbstractWith the growing availability of different knowledge graphs in a variety of domains, question answering over knowledge graph (KG-QA) becomes a prevalent information retrieval approach. Current KG-QA methods usually resort to semantic parsing, search or neural matching models. However, they cannot well tackle increasingly long input questions and complex information needs. In this work, we propose a new KG-QA approach, leveraging the rich domain context in the knowledge graph. We incorporate the new approach with question and answer domain context descriptions. Specifically, for questions, we enrich them with users’ subsequent input questions within a session and expand the input question representation. For the candidate answers, we equip them with surrounding context structures, i.e., meta-paths within the targeting knowledge graph. On top of these, we design a cross-attention mechanism to improve the question and answer matching performance. An experimental study on real datasets verifies these improvements. The new approach is especially beneficial for specific knowledge graphs with complex questions.

Published: November 2019

Abstract
We consider optimal attacks or immunization schemes on different models of random graphs. We derive bounds for the minimum number of nodes needed to be removed from a network such that all remaining components are fragments of negligible size.We obtain bounds for different regimes of random regular graphs, Erdős-Rényi random graphs, and scale free networks, some of which are tight. We show that the performance of attacks by degree is bounded away from optimality.Finally we present a polynomial time attack algorithm and prove its optimal performance in certain cases.
Einflussfaktoren und Folgen des Ausfalls gesetzlicher Ruhepausen bei Pflegekräften in Deutschland
Authors: Lohmann-Haislah Andrea , Wendsche Johannes , Schulz Anika , Schöllgen Ina , Pinzon Luis Carlos Escobar 
Published: November 2019

ZusammenfassungDer Pflegeberuf ist mit hoher körperlicher und psychischer Belastung verbunden. Infolgedessen finden sich in der Kranken- und Altenpflege erhöhte Risiken für körperliche und psychische Beschwerden. Dabei dürfte sich die Belastungssituation in den letzten Jahren aufgrund struktureller und organisationaler Veränderungen im Pflegebereich, gestiegenem Pflegeaufwand und Problemen mit einer ausreichenden Fachkräftesicherung verstärkt haben. Insofern ist es wichtig, solche Arbeitsmerkmale zu stärken, die beeinträchtigende Beanspruchungsfolgen zu mindern vermögen und damit eine gesunde und sichere Arbeit ermöglichen. Arbeitspausen stellen eine solche Arbeitsressource dar. In Deutschland sind Mindestpausenzeiten gesetzlich verpflichtend. Verschiedene Studien zeigten allerdings, dass Pausen bei Pflegetätigkeiten überdurchschnittlich häufig ausfallen, verkürzt werden oder zeitlich nicht wie geplant genommen werden können. Über Treiber und Folgen des Ausfalls von gesetzlichen Ruhepausen ist allerdings wenig bekannt. Dies motivierte zu der nachfolgenden Untersuchung. Grundlage der Auswertungen waren für Deutschland repräsentative Befragungsdaten von Erwerbstätigen, darunter Beschäftigte aus dem Bereich Kranken- und Altenpflege (N = 1003; Krankenpflegen = 685, Altenpflegen = 318), die im Rahmen der im Querschnitt angelegten 6. Welle der BIBB/BAuA-Erwerbstätigenbefragung 2012 gewonnen wurden. Es zeigte sich, dass Pausen signifikant häufiger im Alten- und Krankenpflegebereich ausfallen als bei sonstigen Beschäftigten. Als Hauptgründe für den Pausenausfall werden sowohl in der Kranken- als auch in der Altenpflege hohe Arbeitsmengen angegeben. Weitere Analysen zeigen, dass fehlende Informationen, Merkmale hoher Arbeitsintensität, Schichtarbeit, das Innehaben einer Führungsposition, mangelnde Selbstbestimmung beim Pausenzeitpunkt und Wochenendarbeit mit erhöhtem Pausenausfall einhergehen. Zudem lassen Beschäftigte mit einem unbefristeten Vertrag häufiger die Pause ausfallen, als die mit einem befristeten Vertrag. Bei Betrachtung psychosomatischer Beschwerden zeigt sich, dass die Beschäftigten in der Pflege mit Pausenausfall häufiger psychosomatische Beschwerden angeben als die ohne Pausenausfall, ebensolches gilt für die Muskel-Skelett-Beschwerden. Es wird aber auch deutlich, dass Pausen selbst unter hohen Arbeitsanforderungen diese negativen Beanspruchungsfolgen reduzieren können.Praktische Relevanz:Zur Sicherung der Versorgung im Gesundheitswesen sowie der Gesundheit und Beschäftigungsfähigkeit der dort arbeitenden Pflegekräfte sollte dem Ausfall von gesetzlichen Ruhepausen in Zukunft besser vorgebeugt werden.
Estimation, diagnostics, and extensions of nonparametric Hawkes processes with kernel functions
Authors: Zhuang Jiancang 
Published: November 2019

AbstractThe Hawkes self-exciting model has become one of the most popular point-process models in many research areas in the natural and social sciences because of its capacity for investigating the clustering effect and positive interactions among individual events/particles. This article discusses a general nonparametric framework for the estimation, extensions, and post-estimation diagnostics of Hawkes models, in which we use the kernel functions as the basic smoothing tool.
