POLY-VICTIMIZATION IN POLISH ADOLESCENTS Poly-victimization in Polish Adolescents: Risk Factors and the Moderating Role of Coping Children and adolescents are particularly vulnerable to victimization and can experience an array of different forms, such as community violence, maltreatment by caregive

Children and adolescents are particularly vulnerable to victimization and can experience an array of different forms, such as community violence, maltreatment by caregivers, and peer victimization. Those who face exposure to multiple, different types of victimization in separate incidents, have been labelled “poly-victims” (Finkelhor, Ormrod, Turner, & Hamby, 2005b). For such children, victimization appears to be more of a condition than an event (Finkelhor, Ormrod, & Turner, 2007b). Research has shown that experiences of multiple victimizations in childhood are common. For example, in a sample of Spanish adolescents aged 12-17 years, 19.3% were classified as poly-victims (Pereda, Guilera, & Abad, 2014). Rates of poly-victimization have, however, been shown to vary depending on the country studied. For example, in Russia retrospective reports of victimizations experienced over the whole childhood-adolescence period revealed 45% reported experiencing 8-14 types of victimizations and 11% reported 15 or more types (Bogolyubova, Skochilov, & Smykalo, 2015).
Counting public transport passenger using WiFi signatures of mobile devices

Public transport, or mass transit, is believed to bring several benefits, including energy efficiency, air quality and an economy of scale with respect to total public transport costs. An important factor in providing the public with cost-efficient and timely service, is an ability to do resource planning and optimization based on up-to-date data on passenger counts and flows. In this work we give a novel approach to counting the number of passengers on public bus transport based on WiFi signatures from any mobile devices carried onto the transport vehicle. This provides traffic planners with an up-to-date and relatively cost-effective data source.
New lignan from the rattan stems of Schisandra chinensis

Abstract A new lignan named schilignan F (1), together with twelve known ones (2–13), were isolated from the rattan stems of Schisandra chinensis. Their chemical structures were elucidated by spectroscopic methods including one and two-dimensional NMR spectra referring to the literatures as well as high-resolution mass spectrometric analysis. All compounds were evaluated for their cytotoxicities against human Hela cancer cell lines in vitro. The results showed that compounds 2, 6 and 8 exhibited weak cytotoxic activity with IC50 values of 30.6, 86.3 and 41.0 μM, and cisplatin showed cytotoxic activity with IC50 value of 27.3 μM.
On the ergodicity of the adaptive Metropolis algorithm on unbounded domains

This paper describes sufficient conditions to ensure the correct ergodicity of the Adaptive Metropolis (AM) algorithm of Haario, Saksman, and Tamminen (9), for target distributions with a non-compact support. The conditions ensuring a strong law of large numbers and a central limit theorem require that the tails of the target density decay super-exponentially and have regular contours. The result is based on the ergodicity of an auxiliary process that is sequentially constrained to feasible adaptation sets, and independent estimates of the growth rate of the AM chain and the corresponding geometric drift constants. The ergodicity result of the constrained process is obtained through a modification of the approach due to Andrieu and Moulines (1).
Social integration, perceived discrimination, and self-esteem in mid- and later life: intersections with age and neuroticism

ABSTRACT Objectives: Social relations can influence well-being throughout the life course. Integration in one's community may serve as a source of social support whereas negative interactions such as day-to-day discrimination can be psychosocial stressors, particularly for neurotic persons. Yet social connectedness may vary in importance across the age range. Individuals trim their social networks in later life to optimize emotional well-being, but older adults may also be at heightened risk of social isolation. This study examines the impacts of social integration and perceived discrimination on self-esteem, and whether such impacts differ according to individuals’ age and/or neuroticism. Method: Random effects models analyzed 2,982 observations from 1,882 individuals who participated in at least one of the two most recent waves of the National Survey of Midlife Development in the United States (2004–2014). Results: Self-esteem displayed a minor cubic trajectory across the age range, including declines after age 70. Social integration, perceived discrimination, and neuroticism were all significantly associated with self-esteem, in the expected directions. Self-esteem trajectories varied according to the level of social integration, such that low social integration exacerbated later life declines in self-esteem. The influence of social integration on self-esteem was also stronger at higher levels of neuroticism. Perceived discrimination's influence on self-esteem did not vary by participants’ age or neuroticism. Discussion: Social ties are influential for well-being across the life course, but may take on added importance in later life. Oldest-old and neurotic adults are at particular risk of experiencing low self-esteem if they lack integration with their community.
Burnout and Work Demands Predict Reduced Job Satisfaction in Health Professionals Working In a Surgery Clinic

BACKGROUND: Burnout syndrome develops in health professionals (HPs) as a result of exposure to chronic emotional and interpersonal workplace stressors. Research demonstrates the links between burnout, work demands, and job satisfaction in hospital HPs. AIMS: To examine the associations between burnout, work demands and job satisfaction, and to demonstrate the mediation effect of emotional exhaustion on the relationship between work demands and job satisfaction in surgery clinic HPs. METHODS: Maslach Burnout Inventory was used for assessment of burnout. Work demands and job satisfaction were measured with Hospital Experience Scale and Job Satisfaction Survey, respectively. In order to examine the role of emotional exhaustion, depersonalization, and work demands, controlling for age, hospital tenure, and unit tenure, a hierarchical multiple regression models were tested for each job satisfaction factor. RESULTS: Job satisfaction was negatively predicted by emotional exhaustion. Certain types of work demands negatively predicted different factors of job satisfaction. Emotional exhaustion was a significant partial mediator of the relationship between work demands and job satisfaction. CONCLUSIONS: Adequate management of work demands, particularly excessive workload, time pressure, and lack of staff can lead to prevention of burnout and reduced job satisfaction in surgery clinic HPs, and contribute to better quality of patient care.
The End of a Myth: Distributed Transaction Can Scale

The common wisdom is that distributed transactions do not scale. But what if distributed transactions could be made scalable using the next generation of networks and a redesign of distributed databases? There would be no need for developers anymore to worry about co-partitioning schemes to achieve decent performance. Application development would become easier as data placement would no longer determine how scalable an application is. Hardware provisioning would be simplified as the system administrator can expect a linear scale-out when adding more machines rather than some complex sub-linear function, which is highly application specific. In this paper, we present the design of our novel scalable distributed database system NAM-DB and show that distributed transactions with the very common Snapshot Isolation guarantee can indeed scale using the next generation of RDMA-enabled network technology without any inherent bottlenecks. Our experiments with the TPC-C benchmark show that our system scales linearly to over 6.5 million distributed transactions per second on 56 machines.
Integration of machine learning and meta-analysis identifies the transcriptomic bio-signature of mastitis disease in cattle

Gram-negative bacteria such as Escherichia coli (E. coli) are assumed to be among the main agents that cause severe mastitis disease with clinical signs in dairy cattle. Rapid detection of this disease is so important in order to prevent transmission to other cows and helps to reduce inappropriate use of antibiotics. With the rapid progress in high-throughput technologies, and accumulation of various kinds of ‘-omics’ data in public repositories, there is an opportunity to retrieve, integrate, and reanalyze these resources to improve the diagnosis and treatment of different diseases and to provide mechanistic insights into host resistance in an efficient way. Meta-analysis is a relatively inexpensive option with good potential to increase the statistical power and generalizability of single-study analysis. In the current meta-analysis research, six microarray-based studies that investigate the transcriptome profile of mammary gland tissue after induced mastitis by E. coli infection were used. This meta-analysis not only reinforced the findings in individual studies, but also several novel terms including responses to hypoxia, response to drug, anti-apoptosis and positive regulation of transcription from RNA polymerase II promoter enriched by up-regulated genes. Finally, in order to identify the small sets of genes that are sufficiently informative in E. coli mastitis, the differentially expressed gene introduced by meta-analysis were prioritized by using ten different attribute weighting algorithms. Twelve meta-genes were detected by the majority of attribute weighting algorithms (with weight above 0.7) as most informative genes including CXCL8 (IL8), NFKBIZ, HP, ZC3H12A, PDE4B, CASP4, CXCL2, CCL20, GRO1(CXCL1), CFB, S100A9, and S100A8. Interestingly, the results have been demonstrated that all of these genes are the key genes in the immune response, inflammation or mastitis. The Decision tree models efficiently discovered the best combination of the meta-genes as bio-signature and confirmed that some of the top-ranked genes -ZC3H12A, CXCL2, GRO, CFB- as biomarkers for E. coli mastitis (with the accuracy 83% in average). This research properly indicated that by combination of two novel data mining tools, meta-analysis and machine learning, increased power to detect most informative genes that can help to improve the diagnosis and treatment strategies for E. coli associated with mastitis in cattle.
Breakfast habits affect overall nutrient profiles in adolescents

Abstract Objective To describe breakfast consumption patterns, on a nutrient and food item level, in Belgian adolescents. Design A 7-day estimated food record was administered in a cross-sectional survey. Setting Secondary schools in Ghent, Belgium. Subjects A total of 341 adolescents (13–18 years old), multistage clustered sampling. Results The energy contribution of breakfast to daily energy intake was on average 15.7% in boys and 14.9% in girls. Significantly more overweight girls and significantly more girls following vocational training were categorised as eating a low-quality breakfast. In boys, the energy contribution of polysaccharides was significantly higher in consumers of good-quality breakfasts. The intake of all selected micronutrients was significantly higher in consumers of good-quality breakfasts. In girls, the total energy intake and the proportional intake of proteins and polysaccharides were significantly higher in consumers of good-quality breakfasts, while the proportional contribution of total fat, monounsaturated and polyunsaturated fatty acids was significantly lower in these girls. The intake of all micronutrients was significantly higher in girls consuming a good-quality breakfast. In all adolescents, consumers of a good-quality breakfast had significantly higher intakes of bread, fruit, vegetables, milk and milk products, and fruit juice, while intake of soft drinks was significantly lower than in consumers of low-quality breakfasts. Conclusions Consumers of a good-quality breakfast had a better overall dietary pattern – on a nutrient and food group level – than consumers of a low-quality breakfast. A daily breakfast, including whole-grain products, fruit and (semi-) skimmed milk products or an alternative source of calcium, is recommended.
The Critical Role of Self-Contact for Embodiment in Virtual Reality

With the broad range of motion capture devices available on the market, it is now commonplace to directly control the limb movement of an avatar during immersion in a virtual environment. Here, we study how the subjective experience of embodying a full-body controlled avatar is influenced by motor alteration and self-contact mismatches. Self-contact is in particular a strong source of passive haptic feedback and we assume it to bring a clear benefit in terms of embodiment. For evaluating this hypothesis, we experimentally manipulate self-contacts and the virtual hand displacement relatively to the body. We introduce these body posture transformations to experimentally reproduce the imperfect or incorrect mapping between real and virtual bodies, with the goal of quantifying the limits of acceptance for distorted mapping on the reported body ownership and agency. We first describe how we exploit egocentric coordinate representations to perform a motion capture ensuring that real and virtual hands coincide whenever the real hand is in contact with the body. Then, we present a pilot study that focuses on quantifying our sensitivity to visuo-tactile mismatches. The results are then used to design our main study with two factors, offset (for self-contact) and amplitude (for movement amplification). Our main result shows that subjects' embodiment remains important, even when an artificially amplified movement of the hand was performed, but provided that correct self-contacts are ensured.
Fusion Engineering and Design A volumetric neutron source for fusion nuclear technology testing and development

Research and development (R&D) needs to construct and operate fusion nuclear technology (FNT) components for DEMO have been investigated. Non-fusion facilities, i.e. non-neutron test stands, fission reactors and acceleratorbased neutron sources, can and should play a role in FNT R&D because of their availability and low cost. However, none of the FNT critical issues will be resolved by testing in non-fusion facilities because of their serious limitations on simulating multiple integrated effects of the fusion environment and their lack of adequate test volume. Testing of FNT components, particularly blankets, in fusion facilities is necessary. The FNT requirements on fusion testing are a 1-2 MW m 2 neutron wall load, steady state plasma operation, a fluence of greater than 6 MW years m -2 and a test area greater than 10 m 2. Requirements on reliability growth and component engineering development are the most demanding. Calculations of both expected and tolerable failure rates and reliability growth testing requirements for the blanket lead to a number of important conclusions: (1) achieving a fluence of about 6 MW years m -2 at the test modules with about six to 12 test modules per blanket concept is crucial to achieving a DEMO reactor availability in the 40-50% range with 90% confidence, (2) achieving a DEMO reactor availability of 60% may not be possible with 90% confidence for any practical blanket test program with present design concepts. The required mean time between failure for the blanket is much longer than that achieved in other existing and perhaps less complex technologies, (3) the mean down-time to replace (MTTR) or to recover from a random failure in the blanket must be kept on the order of 1 week or less in order to achieve the required blanket and reactor system availabilities and (4) the length of MTTR must be by itself one of the crucial objectives for testing in fusion facilities. Scenarios for fusion facilities to provide the data base for DEMO have been evaluated. A strategy based on the International Thermonuclear Experimental Reactor (ITER) alone results in unacceptably high risk and long delays in DEMO operation. A plasma-based volumetric neutron source (VNS) facility is proposed for construction and operation parallel to ITER. VNS will serve as a dedicated facility to test and develop FNT components for DEMO. An attractive design envelope for a small-sized tokamak VNS exists with driven (Q ~ I -3 ) steady state plasma and normal conducting copper toroidal field coils. Operation of VNS in parallel to ITER reduces the risk to DEMO and results in net savings in the overall R&D cost to DEMO. Elsevier Science S.A.

Effect of Fluoride on the Morphology and Electrochemical Property of Co3O4 Nanostructures for Hydrazine Detection

In this paper, we systematically investigated the influence of fluoride on the morphology and electrochemical property of Co3O4 nanostructures for hydrazine detection. The results showed that with the introduction of NH4F during the synthesis process of Co3O4, both Co(CO3)0.5(OH)·0.11H2O and Co(OH)F precursors would be generated. To understand the influence of F on the morphology and electrochemical property of Co3O4, three Co3O4 nanostructures that were respectively obtained from bare Co(CO3)0.5(OH)·0.11H2O, Co(OH)F and Co(CO3)0.5(OH)·0.11H2O mixtures and bare Co(OH)F were successfully synthesized. The electrochemical tests revealed the sensing performance of prepared Co3O4 nanostructures decreased with the increase in the fluoride contents of precursors. The more that dosages of NH4F were used, the higher crystallinity and smaller specific surface area of Co3O4 was gained. Among these three Co3O4 nanostructures, the Co3O4 that was obtained from bare Co(CO3)0.5(OH)·0.11H2O-based hydrazine sensor displayed the best performances, which exhibited a great sensitivity (32.42 μA·mM−1), a low detection limit (9.7 μΜ), and a wide linear range (0.010–2.380 mM), together with good selectivity, great reproducibility and longtime stability. To the best of our knowledge, it was revealed for the first time that the sensing performance of prepared Co3O4 nanostructures decreased with the increase in fluoride contents of precursors.
Hepatic resection compared to chemoembolization in intermediate‐ to advanced‐stage hepatocellular carcinoma: A meta‐analysis of high‐quality studies

According to the American Association for the Study of Liver Diseases (AASLD) treatment guidelines for hepatocellular carcinoma (HCC), the role of surgery has been expanded beyond the Barcelona Clinic Liver Cancer (BCLC) algorithm. We compared primary hepatectomy (PH) with transarterial chemoembolization (TACE) in patients with intermediate‐ to advanced‐stage (BCLC stage B/C) HCC to determine the current evidence. Through a database search, we included 18 high‐quality studies (one randomized controlled trial [RCT], five propensity‐score matching nonrandomized comparative trials [NRCTs], and 12 NRCTs) that compared survival outcomes of 5,986 patients after PH and TACE. We found significant survival benefits for PH over TACE in BCLC stage B/C patients (hazard ratio [HR], 0.59; 95% confidence interval [CI], 0.51‐0.67; P < 0.00001; I2 = 84%). According to the BCLC, both stage B and stage C patients showed significantly better overall survival (OS) for PH compared to TACE (HR, 0.53; 95% CI, 0.43‐0.65; P < 0.00001; I2 = 77%; HR, 0.67; 95% CI, 0.59‐0.77; P < 0.00001; I2 = 79%, respectively). Five‐year survival rates for PH were significantly higher than those for TACE in BCLC stage B/C, stage B, and BCLC stage C patients (odds ratio [OR], 2.71, 2.77, and 3.03, respectively; all P < 0.00001). Survival benefits persisted across subgroup, sensitivity, and metaregression analyses; interstudy heterogeneity remained constant. Conclusion: This meta‐analysis suggests that surgical resection provides survival benefits in patients with intermediate‐ to advanced‐stage HCC. The evidence found herein may assist in the choice of treatment modality based on diverse definitions of operability. (Hepatology 2018).
Blood Sampling in Newborns: A Systematic Review of YouTube Videos

Objective of this study was to conduct a systematic review of YouTube videos showing neonatal blood sampling, and to evaluate pain management and comforting interventions used. Selected videos were consumer- or professional-produced videos showing human newborns undergoing heel lancing or venipuncture for blood sampling, videos showing the entire blood sampling procedure (from the first attempt or puncture to the time of application of a cotton ball or bandage), publication date prior to October 2014, Portuguese titles, available audio. Search terms included “neonate,” “newborn,” “neonatal screening,” and “blood collection. ” Two reviewers independently screened the videos and extracted the following data. A total of 13 140 videos were retrieved, of which 1354 were further evaluated, and 68 were included. Videos were mostly consumer produced (97%). Heel lancing was performed in 62 (91%). Forty-nine infants (72%) were held by an adult during the procedure. Median pain score immediately after puncture was 4 (interquartile range [IQR] = 0-5), and median length of cry throughout the procedure was 61 seconds (IQR = 88). Breastfeeding (3%) and swaddling (1.5%) were rarely implemented. Posted YouTube videos in Portuguese of newborns undergoing blood collection demonstrate minimal use of pain treatment, and maximal distress during procedures. Knowledge translation strategies are needed to implement effective measures for neonatal pain relief and comfort.
Information structures to secure control of globally rigid formations

Sensor and network topologies of rigid formations with distance information between mobile autonomous agents are considered. An approach based on rigidity for creating such topologies was suggested in our previous work. Here, we first illustrate some potential scenarios on formations that require unambiguity in the knowledge of distances between every pair of agents in a formation. Then, we show how a stronger type of rigidity, namely global rigidity, plays a role in creating such unambiguous formations. We draw out and summarize some relevant results from the related mathematical theory of global rigidity; and present some new results on globally rigid formations.
