Published: February 2018

AbstractTrajectory clustering, which aims at discovering groups of similar trajectories, has long been considered as a corner stone task for revealing movement patterns as well as facilitating higher level applications such as location prediction and activity recognition. Although a plethora of trajectory clustering techniques have been proposed, they often rely on spatio‐temporal similarity measures that are not space and time invariant. As a result, they cannot detect trajectory clusters where the within‐cluster similarity occurs in different regions and time periods. In this paper, we revisit the trajectory clustering problem by learning quality low‐dimensional representations of the trajectories. We first use a sliding window to extract a set of moving behaviour features that capture space‐ and time‐invariant characteristics of the trajectories. With the feature extraction module, we transform each trajectory into a feature sequence to describe object movements and further employ a sequence‐to‐sequence auto‐encoder to learn fixed‐length deep representations. The learnt representations robustly encode the movement characteristics of the objects and thus lead to space‐ and time‐invariant clusters. We evaluate the proposed method on both synthetic and real data and observe significant performance improvements over existing methods.
A Practical Grid‐Based Alternative Method to Advective Particle Tracking
Authors: Sbai M.A. 
Published: February 2018

AbstractAdvective particle tracking is a conventional groundwater modeling technique that is widely used as a screening tool but lacks robustness as a reliable method for general applications. In this work, we investigate the suitability of industry‐standard, finite‐difference, grid‐based methods as an alternative to the conventional particle‐tracking approach. The presented method is classified as a particular case of the more general forward‐ or backward‐in‐time advective‐dispersive probabilistic transport approaches. The proposed method is used as a powerful screening tool to accurately delineate and visualize capture zones around abstraction wells or outflow boundaries, the swept zones formed by injection wells or inflow boundaries, and the partitions associated with injection‐pumping well doublets or inflowing‐outflowing boundary pairs. Moreover, we show that the forward or backward travel times and residence time distributions are robustly simulated and visualized on the computational grid with little computational effort. Two examples are given to illustrate the key advantages of this method in groundwater applications. The first example considers a synthetic pump‐and‐treat remediation system in an irregularly layered aquifer. The second example involves four doublet wells operating for heat extraction in the Dogger geothermal reservoir in the Paris Basin, a leading European scale project. The presented approach is far more comprehensive as a screening tool than the conventional method, providing a natural intermediate step before processing the more general time‐dependent advective‐dispersive simulations.
Embedding multinational firms in regional business systems: neoliberal and social‐democratic models in Spain
Authors: Gonzalez Menendez María C. , Balbona David Luque , Pruneda Gabriel , Almond Phil 
Published: February 2018

AbstractThe paper analyses how regional actors have mobilised to attract and retain foreign direct investment in two Spanish regions with different political approaches to the management of economic issues, including industrial relations. These regions are Madrid, the main pole of attraction of foreign direct investment in Spain, and Asturias, with a large tradition of heavy industry and a greater dependence on a small number of large employers. It finds the regions have adapted to international competition in substantially different manners and considers the alternative reasons why this might be the case, highlighting the role of organised labour both in the inward investment regimes themselves, and in shaping the nature of the different compromises they involve.
Excess pneumonia and influenza hospitalizations associated with influenza epidemics in Portugal from season 1998/1999 to 2014/2015

Published: February 2018

BackgroundThe aim of this study was to estimate excess pneumonia and influenza (P&I) hospitalizations during influenza epidemics and measure their correlation with influenza vaccine coverage in the 65 and more years old, according to the type/subtype of influenza virus.MethodsThe study period comprised week 40/1998‐40/2015. Age‐specific weekly P&I hospitalizations (ICD‐9: 480‐487) as main diagnosis were extracted from the National Hospital Discharge database. Age‐specific baseline hospitalization rates were estimated by autoregressive integrated moving average (ARIMA) model without time periods with excess hospitalizations. Excess hospitalizations were calculated by subtracting expected hospitalization rates from the observed during influenza epidemic periods. Correlation between excess P&I hospitalizations and influenza vaccine coverage in the elderly was measured with Pearson correlation coefficient.ResultsThe average excess P&I hospitalizations/season was 19.4/105 (range 0‐46.1/105), and higher excess was observed in young children with <2 years (79.8/105) and ≥65 years (68.3/105). In epidemics with A(H3) dominant, the highest excess hospitalizations were observed among 65 and over. Seasons which influenza B or A(H1)pdm09 dominance the highest excess was observed in children with <2 years. High negative correlation was estimated between excess hospitalizations associated with A(H3) circulation and vaccine coverage in the elderly (r = −.653; 95% CI: −0.950 to −0.137).ConclusionOver 80% of the influenza epidemics were associated with excess hospitalizations. However, excess P&I hospitalizations pattern differed from age group and circulating virus. This ecologic approach also identified a reduction in excess P&I associated with A(H3) circulation with increasing vaccine coverage in the elderly.
Proximate mechanisms of the differences in reproductive success of males bearing different alleles of Pgdh – a gene involved in a sexual conflict in bulb mite
Authors: Skwierzyńska Anna M. , Plesnar‐Bielak Agata 
Published: February 2018

AbstractEnzyme polymorphism in phosphogluconate dehydrogenase (Pgdh) is a striking example of single gene polymorphism involved in sexual conflict in bulb mite Rhizoglyphus robini. Males homozygous for the S Pgdh allele were shown to achieve higher reproductive success than FF homozygous males, while negatively influencing fecundity of their female partners. Here, we investigate proximate mechanisms responsible for the increased reproductive success of SS males and find that the S allele is associated with shorter time until copulation, higher copulation frequency and increased sperm production. We also show that Pgdh alleles are probably codominant, with SS males gaining the highest reproductive success, FF males – the lowest – and FS‐heterozygous males taking an intermediate position in all fitness parameters differentiating males of different genotypes. Additionally, we confirm the negative effect that S‐bearing males impose on the fecundity of females they mate with, showing a clear pattern of interlocus sexual conflict. We discuss that this effect is probably associated with increased copulation frequency. Whereas, contrary to what we have predicted, the S allele does not cause increased general male mobility, we speculate that the S allele‐bearing males are more efficient in forcing copulation and/or detecting females.

ObjectivesTo summarize the evidence on the prevalence and preventability of drug‐related hospital readmissions.DesignA systematic review was performed of studies that examined drug‐related hospital readmissions. PubMed, EMBASE, and the Cochrane Library were searched from inception through August 2016. Reference lists and a citation analysis on Web of Science and Scopus were also consulted. Two reviewers extracted study data with dual assessment of risk of bias. Prevalence and preventability of readmission due to drugs were calculated. Data were qualitatively summarized according to outcome.ResultsNineteen studies met the eligibility criteria. Nine measured readmissions due to drug‐related problems, seven due to adverse drug reactions, two due to adverse drug events, and one due to drug‐drug interactions. Rates of readmissions due to drugs varied from 3% to 64% (median 21%, interquartile range (IQR) 14–23%). Readmissions were deemed preventable in 5% to 87% of cases (median 69%, IQR 19–84%). Evidence regarding the risk factors for drug‐related readmissions and drugs causing these readmissions was inconsistent.ConclusionAlthough studies show high variability in prevalence and preventability of drug‐related hospital readmissions, readmissions due to drugs seem to occur often, especially in older adults. Further research is needed to specify the causes of preventable readmissions and implement effective interventions to reduce medication‐related hospital admissions.

AbstractBackgroundRecent evidence indicates a role for dietary factors in the pathogenesis of ulcerative colitis (UC). The aim of the present study was to investigate the relationship between dietary patterns and UC risk.MethodsSixty‐two newly diagnosed cases of UC and 124 healthy age and sex‐matched controls were studied. Data on diet was measured using a validated country‐specific food frequency questionnaire. Factor analysis was used to define major dietary patterns based on 28 food groups and nutrient content.ResultsAfter adjustment for confounding factors, subjects who were in the highest tertile of the healthy dietary pattern had a 79% lower risk of UC (odds ratio = 0.21, 95% confidence interval = 0.07–0.59, P = 0.003), whereas the consumption of an unhealthy dietary pattern was associated with a significantly increased risk of UC (odds ratio = 3.39, 95% 95% confidence interval = 1.16–9.90, P = 0.027).ConclusionsThe findings of the present study suggest that dietary patterns are associated with UC risk.
The Power of Chineseness: Flexible Taiwanese Identities amidst Times of Change in Asia and Latin America
Authors: Pinheiro‐Machado Rosana 
Published: February 2018

ResumenNos anos 1970, os laços diplomáticos entre o Paraguai e Taiwan, bem como o boom industrial deste último, incentivaram a migração comercial de taiwaneses para Ciudad del Este—fronteira com Foz do Iguaçu, Brasil. Porém, as reformas econômicas da China reduziram os custos de produção taiwanesa, fazendo com que suas fábricas se alocassem no continente. Tal mudança na política global de valor afetou significativamente a comunidade migrante. Esse fato foi intesificado por uma crise econômica que afetou a fronteira no século XXI. Com base em uma pesquisa etnográfica, eu analiso como identidades flexíveis respondem a essas distintas fases de acumulação flexível. No contexto de transformação econômica, de abundacia ao colapso, a chinesidade se constituia um rescurso movél que, ao mesmo tempo que dava sentido a uma vida desterritorializada, conferia poder e supremacia cultural que culminava em desigualdade e conflito.

Published: February 2018

IntroductionCurrent guidelines recommend coronary artery bypass grafting (CABG) for patients with multivessel coronary disease and left ventricular (LV) dysfunction. However, some patients undergo percutaneous coronary intervention (PCI) or solely medical therapy (MT) in actual practice. The comparison of long‐term outcomes of these three treatment strategies in real world is unclear.MethodsA total of 699 consecutive patients in a single centre from 2004 to 2011 who had TVD and LV ejection fraction ≤40%, no prior PCI or CABG and had completed a median 6.2‐year follow‐up were evaluated. The primary endpoint was all‐cause death. The secondary endpoints included cardiac death, major adverse cardiovascular and cerebrovascular events (MACCE; composite of all‐cause death, myocardial infarction, repeat revascularization, or stroke), and the individual components of the composite endpoint.ResultsOne hundred forty‐two patients (20.3%) underwent PCI, 201 (28.8%) underwent CABG while 356 (50.9%) received MT alone. MT alone was associated with the worst survival (P < 0.001). Compared with PCI, CABG was associated with a similar risk of all‐cause death (hazard ratio [HR], 0.86; 95% confidence interval [CI], 0.52‐1.41; P = 0.54) but lower risks of cardiac death (HR, 0.47; 95%CI, 0.25‐0.91; P = 0.03), repeat revascularization (HR, 0.29; 95%CI, 0.10‐0.85; P = 0.02), and MACCE (HR, 0.63; 95%CI, 0.43‐0.93; P = 0.02).ConclusionsFor patients with TVD and LV dysfunction, both CABG and PCI were associated with a lower risk of mortality compared with MT alone. Compared with PCI, CABG has a lower risk of cardiac death, repeat revascularization, and MACCE.
Dyadic Neural Similarity During Stress in Mother–Child Dyads
Authors: Lee Tae‐Ho , Qu Yang , Telzer Eva H. 
Published: February 2018

Shared psychological processes between individuals occur most between a mother and her child because the mother–child bond is one of the closest forms of human attachment, in which a mother and her child are essentially wired to connect. We recruited mother–child pairs (Ndyad = 19; adolescent: Mage = 13.74, 11 males; mothers: Mage = 44.26), who each completed an fMRI scan. We examined dyadic neural representational similarity as adolescents completed a stress task and mothers observed their child's performance during the same task. On average, mothers and their children did not show similar neural patterns during stress. However, neural similarity varied depending on family connectedness, such that only dyads reporting high family connectedness showed similar neural profiles. Importantly, increased neural similarity was associated with reduced stress in youth, suggesting that shared neural profiles in mother–child dyads enhance adolescents’ psychological well‐being.
Within‐subjects verbal lie detection measures: A comparison between total detail and proportion of complications
Authors: Vrij Aldert , Leal Sharon , Jupe Louise , Harvey Adam 
Published: February 2018

BackgroundWe examined whether the verbal cue, proportion of complications, was a more diagnostic cue to deceit than the amount of information provided (e.g., total number of details).MethodIn the experiment, 53 participants were interviewed. Truth tellers (n = 27) discussed a trip they had made during the last twelve months; liars (n = 26) fabricated a story about such a trip. The interview consisted of an initial recall followed by a model statement (a detailed account of an experience unrelated to the topic of investigation) followed by a post‐model statement recall. The key dependent variables were the amount of information provided and the proportion of all statements that were complications.ResultsThe proportion of complications was significantly higher amongst truth tellers than amongst liars, but only in the post‐model statement recall. The amount of information provided did not discriminate truth tellers from liars in either the initial or post‐model statement recall.ConclusionThe proportion of complications is a more diagnostic cue to deceit than the amount of information provided as it takes the differential verbal strategies of truth tellers and liars into account.
Breathing synchrony in franciscana (Pontoporia blainvillei) and Guiana dolphins (Sotalia guianensis) in Southern Brazil

Published: February 2018

AbstractSynchronous breathing may be a useful proxy for studying other, and perhaps more complex, aspects of cetacean behavior. Here we describe a study conducted in Babitonga Bay, southern Brazil, where we investigated the synchrony of breathing in two small populations of franciscana (Pontoporia blainvillei) and Guiana dolphins (Sotalia guianensis). The bay is affected by different sources of anthropogenic disturbances, such as boat activity and point‐source pollution. We assumed breathing synchrony to be the inverse of the time between breathing surfacing displays of dolphins within a swimming pair, which we refer to as lag. The relationship between lag and anthropogenic and animal‐related variables was evaluated with generalized additive models. For franciscana dolphins, breathing synchrony was only positively related to the proximity between animals. Breathing synchrony in Guiana dolphins was positively related to both the proximity between animals and to group size, and varied significantly depending on the research boat used. Proximal characteristics (i.e., of individuals or of the group) of these dolphin species seem to be more related to the synchronization in breathing than are the environmental variables assessed here. Results presented expand the current knowledge of these two dolphin species and provide general insights into the breathing synchrony for cetaceans.

Published: February 2018

AbstractThe two species of the genusKogiaare widely distributed throughout the world's temperate and tropical oceans, but because they are small and highly cryptic, they are difficult to monitor. The acoustic signals ofK. brevicepshave been described previously, but the signals ofK. simahave remained unknown. Here we present three recordings ofK. sima, two from free‐ranging animals and one from a captive setting, representing both the Atlantic Ocean and Pacific Ocean. The acoustic signals ofK. simaare very similar to the signals ofK. brevicepsand other species that have narrow‐band, high‐frequency (NBHF) clicks. Free‐rangingK. simaproduce “usual” clicks that have mean peak and centroid frequencies of 127–129 kHz, mean −3 dB bandwidth of 10 kHz, mean −10 dB bandwidth of 16–17 kHz, and mean interclick interval of 110–164 ms. AlthoughK. simaclicks cannot yet be distinguished from those ofK. brevicepsor other NBHF clicking species, our detailed description of this species' signals reveals the similarities between the twoKogiaspecies, and thus allows for passive acoustic monitoring of the genusKogiain regions where other NBHF species are not present.
Asymptotic Properties and Information Criteria for Misspecified Generalized Linear Mixed Models
Authors: Yu Dalei , Zhang Xinyu , Yau Kelvin K. W. 
Published: February 2018

SummaryThe problem of misspecification poses challenges in model selection. The paper studies the asymptotic properties of estimators for generalized linear mixed models with misspecification under the framework of conditional Kullback–Leibler divergence. A conditional generalized information criterion is introduced, and a model selection procedure is proposed by minimizing the criterion. We prove that the model selection procedure proposed is asymptotically loss efficient when all the candidate models are misspecified. The model selection consistency of the model selection procedure is also established when the true data-generating procedure lies within the set of candidate models. Simulation experiments confirm the effectiveness of the method proposed. The use of the criterion for model selection is illustrated through an analysis of the European Currency Opinion Survey data.
Error Bounds for the Large‐Argument Asymptotic Expansions of the Lommel and Allied Functions
Authors: Nemes Gergő 
Published: February 2018

AbstractIn this paper, we reconsider the large‐z asymptotic expansion of the Lommel function and its derivative. New representations for the remainder terms of the asymptotic expansions are found and used to obtain sharp and realistic error bounds. We also give re‐expansions for these remainder terms and provide their error estimates. Applications to the asymptotic expansions of the Anger–Weber‐type functions, the Scorer functions, the Struve functions, and their derivatives are provided. The sharpness of our error bounds is discussed in detail, and numerical examples are given.

The Gran Chaco dry forest ecoregion corresponds to the southern portion of the South America diagonal belt of open formations, being one of the most threatened subtropical woodland savannas in the world. The area is still poorly known biologically and has been suffering with impressively high forest cover loss in the last 10 years. Integrating morphological and molecular data, we detected and describe a cryptic new species of lizard genusAmeivulaendemic from the eastern part of this ecoregion, the called Humid Chaco.Ameivula apipensissp nov. is characterised by a whitish brown vertebral stripe in adults and juveniles, a lateral field without ocelli and with overlapping spot, presence of an interfrontoparietal scale in 46.2% of the specimens, 12–17 femoral pores, an hemipenis without lateral sac, five xiphisternal ribs, and by a combination of meristic features as confirmed by discriminant analysis. The new species was recovered sister to a clade from Western Cerrado in our analysis, the first phylogenetic hypothesis for theAmeivulaandGlaucomastixgenera based on 1977 base pairs of three mitochondrial (12S, 16S and cyt‐b) and one nuclear (c‐mos) genes, including all the recognised species at the moment. Maximum parsimony and Bayesian inference recovered the monophyly ofAmeivulaandGlaucomastixwith strong support. Reinforcing previous studies, our results suggest the presence of additional cryptic species inAmeivulafrom the Western Cerrado.
