Published: June 2018

AbstractWhen relating glycaemic index (GI) and glycaemic load (GL) to health outcomes, many prospective cohort studies assess the nutritional exposure only once in time, that is, at the start of the study, presuming a stability in nutritional consumption during the course of the study. The aim of this study is to investigate the reproducibility of GI and GL. This is a prospective cohort study in which 562 middle-aged Belgian adults noted all foods and drinks consumed during 3 d in 2002 and 2012. GI and GL were calculated after reference tables. The Pearson correlation coefficients between 2002 and 2012 were 0·27 for GI and 0·41 for GL. For GI, 33 % of the participants remained in the same quintile between 2002 and 2012, whereas 31 % moved to a non-adjacent quintile. For GL, this was 34 and 28 %, respectively. The lowest and the highest quintiles of GI were the most stable, with 40 and 44 % of the participants staying in the same quintile. This was only 22 % for the fourth quintile. The same tendency was present for GL – that is, the most extreme quintiles were the most stable. This study shows 10-year correlation coefficients for GI and GL below 0·50. Multiple nutritional assessments and limiting the analysis to the extreme quintiles of GI and GL will limit a possible misclassification in the prospective cohort studies owing to the low reproducibility.
Integrated pest management for resource-limited farmers: challenges for achieving ecological, social and economic sustainability
Authors: Bottrell D. G. , Schoenly K. G. 
Published: June 2018

AbstractHailed as the single most important paper published on crop protection in the 20th century, Sternet al. in 1959 formed the conceptual basis for modern integrated pest management (IPM) worldwide. The ecological foundation for IPM envisioned by its authors is as valid today as in 1959. However, adoption by developing country farmers has been low and its advances short-lived. The present paper examines the concept of integration in IPM and criteria for determining whether its control tactics have been integrated harmoniously. The effects of local and regional landscape patterns on pests and on the design of IPM are reviewed, arguing that the agroecosystem must be understood and managed as a living system with the goal of enhancing and conserving agrobiodiversity and keeping ecosystem services intact. Key to IPM adoption is convincing farmers to integrate non-chemical alternatives (e.g. biological control, plant diversification) as primary management components and to apply pesticides judiciously and only after non-chemical components fail to manage pests effectively. Research, extension and policy changes are identified to increase the efficiency, adoption and sustainability of IPM on resource-limited farms. The over-arching challenge is devising communication and support systems that allow resource-limited farmers to try, adopt and sustain IPM that enhances yields and profits in light of the many uncertainties and challenges. Use of information technology, media development, crowdsourcing and rural sociology is advocated to connect farmers to the technical sources required to enhance yields and profits and reduce risks to them, the farming community and the environment.

Published: June 2018

AbstractBackgroundAlthough the DSM is a widely used diagnostic guide, lengthy criteria sets can be problematic and provide the primary motivation to identify short-forms. Using the 11 diagnostic criteria provided by the DSM-5 for alcohol use disorder (AUD), the present study develops a data-driven method to systematically identify subsets and associated cut-offs that yield diagnoses as similar as possible to use all 11 criteria.MethodRelying on data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III), our methodology identifies diagnostic short-forms for AUD by: (1) maximizing the association between the sum scores of all 11 criteria with newly constructed subscales from subsets of criteria; (2) optimizing the similarity of AUD prevalence between the current DSM-5 rule and newly constructed diagnostic short-forms; (3) maximizing sensitivity and specificity of the short-forms against the current DSM-5 rule; and (4) minimizing differences in the accuracy of the short-form across chosen covariates. Replication is shown using NESARC-Wave 2.ResultsMore than 11 000 diagnostic short-forms for DSM-5 AUD can be created and our method narrows down the optimal choices to eight. Results found that ‘Neglecting major roles’ and ‘Activities given up’ could be dropped with practically no change in who is diagnosed (specificity = 100%, sensitivity ⩾ 99.6%) or the severity of those diagnosed (κ = 0.97).ConclusionsWith a continuous improvement model adopted by the APA for DSM revisions, we offer a data-driven tool (a SAS Macro) that identifies diagnostic short-forms in a systematic and reproducible way to help advance potential improvements in future DSM revisions.
The influence of lifecourse financial strains on the later-life health of the Japanese as assessed by four models based on different health indicators
Authors: Sugisawa Hidehiro , Sugihara Yoko , Kobayashi Erika , Fukaya Taro , Liang Jersey 
Published: June 2018

AbstractIn this study, four models used for assessing the influence of lifecourse financial strains on later-life health (the latent period effects, pathway, social mobility and accumulative effects models) were tested in the context of Japan by using different types of health indicators: comorbidity, disabled activities of daily living, disabled cognitive function, self-rated health and depressive symptoms. We hypothesised that suitable models for describing the influence of financial strain would differ according to the type of health indicator used. Participants aged 60–92 years (N = 2,500) were obtained in 2012 by using a two-stage stratified random sampling method. The final number of participants in the sample was 1,324. The results indicate that three models – pathway, accumulative effects and social mobility – describe the influence of a person's lifecourse financial strain on comorbidity, cognitive function, self-rated health and depressive symptoms. In turn, the latent period effects model explains the influence of lifecourse financial strain on comorbidity. However, only the pathway model described the influence of lifecourse financial strain on activities of daily living. These results suggest that disadvantages in lifecourse socio-economic status influence the decline of health in elderly Japanese people, similar to people in Western countries. However, the finding that suitable models for describing the influence of socio-economic status on health will differ according to the type of health indicator is an original contribution of this study.
The kinematic image of RR, PR, and RP dyads
Authors: Rad Tudor-Dan , Scharler Daniel F. , Schröcker Hans-Peter 
Published: June 2018

SUMMARYWe provide necessary and sufficient conditions for all projective transformations of the projectivized dual quaternion model of rigid body displacements that are induced by coordinate changes in moving and/or fixed frame. These transformations fix the quadrics of a pencil and preserve the two families of rulings of an exceptional three-dimensional quadric. Moreover, we fully characterize the constraint varieties of dyads with revolute and prismatic joints in the dual quaternion model. The constraint variety of a dyad with two revolute joints is a regular ruled quadric in a three-space that contains a “null quadrilateral.” If a revolute joint is replaced by a prismatic joint, this quadrilateral collapses into a pair of conjugate complex null lines and a real line but these properties are not sufficient to characterize such dyads. We provide a complete characterization by introducing a new invariant, the “Study fibre projectivity,” and we present examples that demonstrate its potential to explain hitherto not sufficiently well-understood phenomena.
Campylobacter control measures in indoor broiler chicken: critical re-assessment of cost-utility and putative barriers to implementation

Published: June 2018

AbstractAs campylobacteriosis is one of the most important foodborne infections, a European Union (EU)-27 level cost-effectiveness model has been developed on the socio-economic costs and benefits of applying certain control measures for the reduction ofCampylobacterin broiler meat. This is expected to be a gold standard for food safety policymakers in the EU; hence, the validity of its modelling assumptions is essential. The authors of the present paper conducted an independent review of model input parameters on health and economic burden and found that the model most probably overestimated the burden of human campylobacteriosis. A discounted, quality-adjusted life year (QALY)-based European estimate has been developed for human campylobacteriosis and resulted in 15.23 QALY loss per 1000 human gastroenteritis cases. Country-specific cost of illness estimates have been developed for various countries in the EU-27. Based on these model adaptations, a selectedCampylobactercontrol strategy was re-assessed and its high cost-effectiveness was confirmed at the EU level, and also in all but three Member States. Bacteriocin treatment or vaccination of the animals, two alternative control measures were also re-evaluated, and these strategies seemed to be far less cost-effective than the investigated strategy. Putative barriers to the rapid implementation of the investigatedCampylobactercontrol strategy are discussed, and potential solutions are proposed. Further research is required on stakeholder perspectives pertaining to the realistic barriers and implementation opportunities.
Different latent class models were used and evaluated for assessing the accuracy of campylobacter diagnostic tests: overcoming imperfect reference standards?

Published: June 2018

AbstractIn the absence of perfect reference standard, classical techniques result in biased diagnostic accuracy and prevalence estimates. By statistically defining the true disease status, latent class models (LCM) constitute a promising alternative. However, LCM is a complex method which relies on parametric assumptions, including usually a conditional independence between tests and might suffer from data sparseness. We carefully applied LCMs to assess new campylobacter infection detection tests for which bacteriological culture is an imperfect reference standard. Five diagnostic tests (culture, polymerase chain reaction and three immunoenzymatic tests) of campylobacter infection were collected in 623 patients from Bordeaux and Lyon Hospitals, France. Their diagnostic accuracy were estimated with standard and extended LCMs with a thorough examination of models goodness-of-fit. The model including a residual dependence specific to the immunoenzymatic tests best complied with LCM assumptions. Asymptotic results of goodness-of-fit statistics were substantially impaired by data sparseness and empirical distributions were preferred. Results confirmed moderate sensitivity of the culture and high performances of immunoenzymatic tests. LCMs can be used to estimate diagnostic tests accuracy in the absence of perfect reference standard. However, their implementation and assessment require specific attention due to data sparseness and limitations of existing software.
Multispectral imaging – a new tool in seed quality assessment?

Published: June 2018

AbstractMultispectral imaging is a new technology that is being deployed to assess seed quality parameters. Examples of applications in the detection and identification of fungi on seeds are presented, together with an example of the technology used for maturity determination in sugar beet seed. Results from multispectral imaging are compared with reference methods, and a high correlation is found. Applications of the technique for varietal discrimination and insect damage are also presented. There is a need for non-destructive, reliable and fast techniques, and it is concluded that multispectral imaging has potential for seed quality assessment, in particular for those components associated with surface structure and chemical composition, seed colour, morphology and size.

Published: June 2018

AbstractVolcanic edifices are commonly unstable, with magmatic and non‐magmatic fluid circulation, and elevated temperature gradients having influence on the mechanical strength of edifice and basement rocks. We present new mechanical characterization of the Comiso limestone of the Mount Etna Volcano (Italy) basement to constrain the effects of regional ambient conditions associated with the volcanic system: the effects of pore fluid on rock strength and the effects of distal magmatic heating (~20 °C to 600 °C) at a range of simulated depths (0.2 to 2.0 km). The presence of water promotes ductile behaviour at shallow depths and causes a significant reduction in brittle rock strength compared to dry conditions. Thermal stressing, in which specimens were heated and cooled before mechanical testing at room temperature, has a variable effect for dry and saturated cases. In dry conditions, thermal stressing up to 450 °C homogenizes the strength of the specimen such that the majority of the specimens exhibit the same peak stress; at 600 °C, the brittle failure is promoted at lower differential stress. The presence of water in thermally‐stressed specimens promotes ductile behaviour and reduces peak strength. Acoustic emission monitoring suggests that accumulated damage is associated with the heating–cooling sequence, particularly in the 300–450‐600°C. Based on conduction modeling, we estimate this temperature range could affect basement rocks up to 300 m away from minor sheet intrusions and much further with larger bodies. Considering the dyke spacing beneath Etna, these conditions may apply to a significant percentage of the basement, promoting ductile behaviour at relatively shallow depths.
Role of Meteorologically Induced Water Level Oscillations on Bottom Shear Stress in Freshwater Estuaries in the Great Lakes

Published: June 2018

AbstractThe role of meteorologically induced water level oscillations (MIWLOs) on bottom shear stresses in a freshwater estuary in the Great Lakes is investigated. Atmospheric data including air pressure, wind speed and direction, and radar reflectivity are compiled, and comprehensive field measurements including velocity profiles, water levels, river discharges, and bottom sediment properties in the Manistique River (MR) estuary, Michigan, are conducted. Wavelet and cross‐wavelet analysis reveals that large velocity events (>0.5 m/s) in the MR estuary are generated by high‐frequency MIWLOs (i.e., meteotsunamis and high‐frequency seiches) induced by energetic oscillations in air pressure and/or wind speed and direction with periods below 2 hr. Measured velocity profiles reveal that MIWLO‐dominated conditions can increase bottom shear stress by an order of magnitude in comparison with river‐dominated flow conditions. The hydrodynamic model indicates that bottom shear stresses under both the downstream and upstream flows during the MIWLO‐dominated event were significantly larger than those during river‐dominated conditions. The interactions of MIWLOs and flood flows can significantly alter the bottom shear stresses in the main river channel, and MIWLOs are revealed to be the principal resuspension mechanism in areas such as the upstream tributary branches where flood flows individually do not cause resuspension. Furthermore, the role of MIWLOs asymmetry in fresh water Great Lakes estuaries on velocity residuals and net sediment transport is revealed and discussed. Overall, this paper fills important knowledge gaps in the role of MIWLOs on sediment transport in enclosed basin estuaries, thus providing essential information for coastal management and estuarine remediation.
Online Model Parameter Estimation With Ensemble Data Assimilation in the Real Global Atmosphere: A Case With the Nonhydrostatic Icosahedral Atmospheric Model (NICAM) and the Global Satellite Mapping of Precipitation Data

Published: June 2018

AbstractThis study aims to improve precipitation forecasts by estimating model parameters of a numerical weather prediction model with an ensemble‐based data assimilation method. We implemented the parameter estimation algorithm into a global atmospheric data assimilation system NICAM‐LETKF, which incorporates Nonhydrostatic Icosahedral Atmospheric Model (NICAM) and the Local Ensemble Transform Kalman Filter (LETKF). This study estimated a globally uniform model parameter of a large‐scale condensation scheme known as the B1 parameter of Berry's parameterization. We conducted an online estimation of the B1 parameter using the Global Satellite Mapping of Precipitation (GSMaP) data and successfully reduced NICAM's precipitation forecast bias relative to the GSMaP data, especially for weak rains. The estimated B1 parameter evolved toward the optimal value obtained by manual tuning. The parameter estimation also mitigated a dry bias for the lower troposphere in the Tropics. However, the estimated B1 intensified biases for cloud water mixing ratio and outgoing long‐wave radiation in the regions where shallow clouds are dominant. This is because only precipitation data were used to estimate the optimal value of B1, and more constraints will be required to obtain a suitable value for climatological simulations.
Mechanisms of Abrupt Extreme Precipitation Change Over the Northeastern United States
Authors: Huang Huanping , Winter Jonathan M. , Osterberg Erich C. 
Published: June 2018

AbstractIn 1996, the northeastern United States experienced an abrupt increase in extreme precipitation, but the causal mechanisms driving this increase remain poorly understood. We find that 89% of the 1996–2016 increase relative to 1979–1995 is explained by only 273 unique extreme events affecting >5 stations and occurring in the months of February, March, June, July, September, and October. We use daily weather maps to classify the 273 extreme precipitation events by meteorological cause (tropical cyclones, fronts, and extratropical cyclones) and use reanalysis data to determine large‐scale changes in the atmosphere and ocean associated with increased extreme precipitation for each classification. Results show that tropical cyclones account for almost half (48%) of the post‐1996 extreme precipitation increase, while fronts and extratropical cyclones are responsible for 25% and 15% of the increase, respectively. The remaining 11% is from extreme events in the other 6 months of the year and extreme events that affected <5 stations. The increase in extreme precipitation from tropical cyclones after 1996 is associated with a shift to the Atlantic Multidecadal Oscillation warm phase, higher total column water vapor, and potentially weakened steering winds. September and October tropical cyclones caused significantly more extreme precipitation during the current Atlantic Multidecadal Oscillation warm phase (1996–present) than during the last warm phase (1928–1962), despite the same number of northeast tropical cyclones in both periods. Increased extreme precipitation from fronts is associated with a wavier (higher amplitude) jet stream, which likely facilitates the development of more frequent fronts through the advection of cool northern air into the American Midwest.
Paradigm Shifts on Flood Risk Management in Japan: Detecting Triggers of Design Flood Revisions in the Modern Era
Authors: Nakamura Shinichiro , Oki Taikan 
Published: June 2018

AbstractFlood risk management (FRM) has repeatedly evolved through paradigm shifts in human history. In modern FRM, a design flood, which reflects the protection standard or safety level of the FRM, is one of the most important elements. It has been historically revised and increased to reflect the sociohydrological situation of each era. Through this study we aimed to identify these changes to FRM and their reasons (after the advent of the modern society in Japan), focusing on the design flood revision triggers in 109 river basins. We extracted all these triggers through critical reviews of governmental reports (and other historical resources), then tried to identify and divide this time period into a few eras, based on these shifts. In addition, we performed a quantitative trend analysis of several sociohydrological variables that contributed to (or refracted) the shifts and conducted a qualitative analysis of their sociohydrological backgrounds. The revision triggers could be classified into five categories: “national policy change,” “mega flood,” “dam construction,” “economic growth,” and “others.” From the transition of triggers, the Japanese modern history of FRM was divided into three eras: “Era 1: 1910–1935, changing society,” “Era 2: 1935–1970, response to mega floods,” and “Era 3: 1970–2010, response to economic growth.” The paradigms shifted in each era due to variations in both socio‐hydrological events and backgrounds. The results showed that the Japanese FRM paradigm has shifted from “green society” to “technological society,” with respect to human‐technology‐flood evolution.
Source Complexity of the 2015 Mw 7.9 Bonin Earthquake

Published: June 2018

AbstractThe 30 May 2015 Mw 7.9 Bonin earthquake, one of the largest and deepest earthquakes ever recorded by modern seismology, provides a unique opportunity to study the source process and physical mechanisms of deep‐focus earthquakes. We develop a novel back projection technique that allows source imaging in full three‐dimensional space with a high‐depth resolution. Our results indicate an initial SW‐NE bilateral source propagation followed by a northwest source extension. The multiple‐source inversion reveals a two‐step source process with propagating directions nearly perpendicular to each other, consistent with the 3‐D back projection result. The spatial distribution and focal mechanisms of the subevents cannot be modeled by a single planar rupture, which may display a curved rupture plane or subevents crossing multiple fault interfaces. The complex source process can be best explained by stress or structure heterogeneity within the deep slab.
