Published: April 2019

AbstractA cross‐sectional study was conducted to estimate the seroprevalence of bovine brucellosis in smallholder farms in seven regions in Pakistan, identify herd and individual level risk factors for seropositivity and assess the level of engagement of farmers with risk factors. In total, 1063 cattle and buffalo belonging to 420 herds in seven districts were sampled. The Rose Bengal test (RBT), indirect enzyme‐linked immunosorbent assay (I‐ELISA) and competitive enzyme‐linked immunosorbent assay (C‐ELISA) were used for the serological diagnosis of bovine brucellosis on all the serum samples. The associations between herd‐and animal‐level risk factors and seropositivity were investigated using logistic regression analyses. In addition, herd management practice scores, created to quantify the number of management practices undertaken that pose a risk for Brucella transmission, were calculated and compared between seropositive and negative herds within each district. Overall herd and animal prevalence were estimated to be 16.2% (95% CI, 13–20%) and 8.7% (95% CI, 7.2–10.6%), respectively, across all districts sampled. Herds with a history of last trimester abortion were found to be more likely to be positive than herds without such history (OR = 2.06, 95% CI, 1.09–3.89), providing validation of our findings and identifying that clinical disease is occurring in this region. It was also identified that herds with five to eight buffalo (OR = 3.80, 95% CI, 1.69–8.49), and those with more than eight buffalo (OR = 3.81, 95% CI, 1.51–9.58) were more likely to be positive for Brucella than those with less (one to two and three to four) buffaloes present in the herd. The presence of other domestic animals at the farm and purchasing animals in last year were found to have no association with seropositivity. The findings of this study support the need for the development of targeted intervention strategies specific to the disease status of each district.
Estimation of offshore extreme wind from wind‐wave coupled modeling

Published: April 2019

AbstractA coupledwind‐wave modeling system is used to simulate 23 years of storms and estimate offshore extreme wind statistics. In this system, the atmospheric Weather Research and Forecasting (WRF) model and Spectral Wave model for Near shore (SWAN) are coupled, through a wave boundary layer model (WBLM) that is implemented in SWAN. The WBLM calculates momentum and turbulence kinetic energy budgets, using them to transfer wave‐induced stress to the atmospheric modeling. While such coupling has a trivial impact on the wind modeling for 10‐m wind speeds less than 20 ms−1, the effect becomes appreciable for stronger winds—both compared with uncoupled WRF modeling and with standard parameterization schemes for roughness length. The coupled modeling output is shown to be satisfactory compared with measurements, in terms of the distribution of surface‐drag coefficient with wind speed. The coupling is also shown to be important for estimation of extreme winds offshore, where the WBLM‐coupled results match observations better than results from noncoupled modeling, as supported by measurements from a number of stations.
Spatiotemporal variability of the wind power resource in Argentina and Uruguay
Authors: Bianchi Emilio , Solarte Andrés , Guozden Tomás 
Published: April 2019

AbstractThe spatiotemporal variability of the wind power resource over Argentina and Uruguay is assessed based on the Modern‐Era Retrospective Analysis for Research and Applications 2 (MERRA2) dataset. Hourly wind speeds were interpolated to 100‐m height, and then, wind power outputs were computed using power curves of three International Electrotechnical Commission (IEC) wind classes. The time series of wind power outputs were filtered using a fast Fourier transform (FFT) to separate regular (annual and daily) from irregular (interannual and synoptic scale) cycles. An empirical orthogonal function analysis was applied to the resulting datasets to obtain the main modes of variability. The results show that the combination of wind power outputs from southern and northern Patagonia broadly follows the average annual electric load. Patagonia exhibits the highest variability on the interannual, annual, and synoptic timescales. On the interannual and synoptic timescales, the variability modes are associated with known and distinct atmospheric circulation modes. The interannual modes of variability are associated with opposite surface level pressure (SLP) anomalies between middle and high latitudes.
Multiple and multiway correspondence analysis
Authors: Beh Eric J. , Lombardo Rosaria 
Published: April 2019

One of the most popular, and versatile, ways of visually analyzing the associating between categorical data is to perform a correspondence analysis on the contingency table that is formed from their cross‐classification. Traditionally the analysis of multiple categorical variables involves transforming such a table into a two‐way form through “flattening,” stacking or by some other means; doing so leads to simple or multiple correspondence analysis. Although such a transformation does not always preserve some of the truly multivariate nature of the association. Therefore one may instead adopt the less common multiway correspondence analysis. This paper will briefly explore the development, literature, and possible research opportunities of multiple and multiway correspondence analysis.This article is categorized under:

Convergence of solutions to history‐dependent variational‐hemivariational inequalities
Authors: Xiao Yi‐bin , Sofonea Mircea 
Published: April 2019

AbstractIn this paper, we state and prove two convergence results for the solution of a history‐dependent variational‐hemivariational inequality. The first one concerns the pointwise convergence of the solution with respect to the data, including the set of constraints, the nonlinear operator and the two functionals which govern the inequality. The second result, obtained under additional assumptions, concerns the uniform convergence of the solution with respect to the set of constraints. These convergence results allow us to consider two general optimization problems for which we prove the existence of minimizers. The mathematical tools developed in this paper are useful in the analysis and control of a large class of boundary value problems which, in a weak formulation, lead to history‐dependent variational‐hemivariational inequalities. To provide an example, we illustrate our results in the study of a nonlinear problem with unilateral constraints and subdifferential boundary conditions.
Effect of a circular Eshelby inclusion on the non‐elliptical shape of a coated neutral inhomogeneity with internal uniform stresses
Authors: Wang Xu , Schiavone Peter 
Published: April 2019

AbstractUsing conformal mapping techniques, we present the design of a coated non‐elliptical neutral inhomogeneity with internal uniform stresses which does not disturb a prescribed uniform anti‐plane stress field in the surrounding matrix when both a circular Eshelby inclusion present in the thick coating and the inhomogeneity itself undergo uniform eigenstrains. An appropriately chosen conformal mapping function maps the doubly connected domain of the thick coating onto an annulus in the image plane. All of the unknown complex constants appearing in the mapping function can be uniquely determined. Detailed numerical results are presented to demonstrate the proposed theory. We also consider a related problem concerning a neutral coated inhomogeneity with internal uniform stresses in the presence of a screw dislocation dipole in the thick coating.

Abstract
The ethanol stress response in ethanologenic yeast during fermentation involves the swishing of several adaptation mechanisms. In Saccharomyces cerevisiae, the Jac1p and Isu1p proteins constitute the scaffold system for the Fe–S cluster assembly. This study was performed using the over-expression of the Jac1p and Isu1p in the industrially utilized S. cerevisiae UMArn3 strain, with the objective of improving the Fe–S assembly/recycling, and thus counteracting the toxic effects of ethanol stress during fermentation. The UMArn3 yeast was transformed with both the JAC1-His and ISU1-His genes-plasmid contained. The Jac1p and Isu1p His-tagged proteins over-expression in the engineered yeasts was confirmed by immunodetection, rendering increases in ethanol tolerance level from a DL50 = ~ 4.5% ethanol (v/v) to DL50 = ~ 8.2% ethanol (v/v), and survival up 90% at 15% ethanol (v/v) comparing to ~ 50% survival in the control strain. Fermentation by the engineered yeasts showed that the ethanol production was increased, producing 15–20% more ethanol than the control yeast. The decrease of ROS and free-iron accumulation was observed in the engineered yeasts under ethanol stress condition. The results indicate that Jac1p and Isu1p over-expression in the S. cerevisiae UMArn3.3 yeast increased its ethanol tolerance level and ethanol production by a mechanism that involves ROS and iron homeostasis related to the biogenesis/recycling of Fe–S clusters dependent proteins.
Local and Organic Preference: Logo versus Text
Authors: Katz Michael , Campbell Benjamin , Liu Yizao 
Published: April 2019

AbstractA choice experiment was conducted concurrently with eye-tracking technology to examine consumer preferences for local and organic produce, notably effects of logo- versus text-labeling formats. We find consumers prefer local to nonlocal, but some consumers will pay a higher premium for logo-labeled produce compared with text-labeled produce. Additionally, we find evidence that a local logo tends to attract attention quicker and hold attention longer compared with a text label. The organic text label was preferred by some consumers compared with the USDA certified organic logo, even with though consumers looked at the logo longer and more often.
Educating for Intellectual Virtue: A Critique from Action Guidance
Authors: Kotzee Ben , Carter J. Adam , Siegel Harvey 
Published: April 2019

AbstractVirtue epistemology is among the dominant influences in mainstream epistemology today. An important commitment of one strand of virtue epistemology – responsibilist virtue epistemology – is that it must provide regulative normative guidance for good thinking. Recently, a number of virtue epistemologists (most notably Baehr) have held that virtue epistemology not only can provide regulative normative guidance, but moreover that we should reconceive the primary epistemic aim of all education as the inculcation of the intellectual virtues. Baehr's picture contrasts with another well-known position – that the primary aim of education is the promotion of critical thinking. In this paper – that we hold makes a contribution to both philosophy of education and epistemology and, a fortiori, epistemology of education – we challenge this picture. We outline three criteria that any putative aim of education must meet and hold that it is the aim of critical thinking, rather than the aim of instilling intellectual virtue, that best meets these criteria. On this basis, we propose a new challenge for intellectual virtue epistemology, next to the well-known empirically driven ‘situationist challenge’. What we call the ‘pedagogical challenge’ maintains that the intellectual virtues approach does not have available a suitably effective pedagogy to qualify the acquisition of intellectual virtue as the primary aim of education. This is because the pedagogic model of the intellectual virtues approach (borrowed largely from exemplarist thinking) is not properly action-guiding. Instead, we hold that, without much further development in virtue-based theory, logic and critical thinking must still play the primary role in the epistemology of education.
The Reliability of Memory: An Argument from the Armchair
Authors: Hasan Ali 
Published: April 2019

AbstractThe “problem of memory” in epistemology is concerned with whether and how we could have knowledge, or at least justification, for trusting our apparent memories. I defend an inductive solution – more precisely, an abductive solution – to the problem. A natural worry is that any such solution would be circular, for it would have to depend on memory. I argue that belief in the reliability of memory can be justified from the armchair, without relying on memory. The justification is, roughly, that my having the sort of experience that my apparent memory should lead me to expect is best explained by the hypothesis that my memories are reliable. My solution is inspired by Harrod's (1942) inductive solution. Coburn (1960) argued that Harrod's solution contains a fatal flaw. I show that my solution is not vulnerable to Coburn's objection, and respond to a number of other, recent and likely objections.
Linear iterative method for closed-loop control of quasiperiodic flows
Authors: Leclercq Colin , Demourant Fabrice , Poussot-Vassal Charles , Sipp Denis 
Published: April 2019

This work proposes a feedback-loop strategy to suppress intrinsic oscillations of resonating flows in the fully nonlinear regime. The frequency response of the flow is obtained from the resolvent operator about the mean flow, extending the framework initially introduced by McKeon & Sharma (J. Fluid Mech., vol. 658, 2010, pp. 336–382) to study receptivity mechanisms in turbulent flows. Using this linear time-invariant model of the nonlinear flow, modern control methods such as structured ${\mathcal{H}}_{\infty }$-synthesis can be used to design a controller. The approach is successful in damping self-sustained oscillations associated with specific eigenmodes of the mean-flow spectrum. Despite excellent performance, the linear controller is however unable to completely suppress flow oscillations, and the controlled flow is effectively attracted towards a new dynamical equilibrium. This new attractor is characterized by a different mean flow, which can in turn be used to design a second controller. The method can then be iterated on subsequent mean flows, until the coupled system eventually converges to the base flow. An intuitive parallel can be drawn with Newton’s iteration: at each step, a linearized model of the flow response to a perturbation of the input is sought, and a new linear controller is designed, aiming at further reducing the fluctuations. The method is illustrated on the well-known case of two-dimensional incompressible open-cavity flow at Reynolds number $Re=7500$, where the fully developed flow is initially quasiperiodic (2-torus state). The base flow is reached after five iterations. The present work demonstrates that nonlinear control problems may be solved without resorting to nonlinear reduced-order models. It also shows that physically relevant linear models can be systematically derived for nonlinear flows, without resorting to black-box identification from input–output data; the key ingredient being frequency-domain models based on the linearized Navier–Stokes equations about the mean flow. Applicability to amplifier flows and turbulent dynamics has, however, yet to be investigated.
ACCOMMODATING RELIGIOUS LAW WITH A CIVIL LEGAL SYSTEM: LESSONS FROM THE JEWISH LAW EXPERIENCE IN FINANCIAL FAMILY MATTERS
Authors: Westreich Avishalom 
Published: April 2019

AbstractThe discussion of legal pluralism focuses on the coexistence of several legal systems, mainly religious and civil ones. But what happens when a process of assimilation—whether imposed or voluntary—characterizes the relationships between the systems? This article analyzes the fascinating process of assimilation of civil principles into religious law in the context of Jewish law and Israeli civil family law. Assimilation, as the article shows, is not the whole picture. The article reveals a corresponding (both open and implicit) struggle for the preservation of religious law principles despite the continuing efforts of civil law for their curtailment, or sometimes, elimination. The result, which is somewhat internally contradictory, suggests a normative pluralistic framework that enables both regimes—the civil and the religious—to preserve their core principles in family law matters.
MINIMUM MODELS OF SECOND-ORDER SET THEORIES
Authors: WILLIAMS KAMERYN J. 
Published: April 2019

AbstractIn this article I investigate the phenomenon of minimum and minimal models of second-order set theories, focusing on Kelley–Morse set theory KM, Gödel–Bernays set theory GB, and GB augmented with the principle of Elementary Transfinite Recursion. The main results are the following. (1) A countable model of ZFC has a minimum GBC-realization if and only if it admits a parametrically definable global well order. (2) Countable models of GBC admit minimal extensions with the same sets. (3) There is no minimum transitive model of KM. (4) There is a minimum β-model of GB+ETR. The main question left unanswered by this article is whether there is a minimum transitive model of GB+ETR.
Riverine people's knowledge of the Vulnerable Amazonian manatee Trichechus inunguis in contrasting protected areas
Authors: Crema Luciana Carvalho , da Silva Vera Maria Ferreira , Piedade Maria Teresa Fernandez 
Published: April 2019

AbstractTraditional knowledge gained through daily interactions with the environment can yield insights into processes at temporal or spatial scales that may be overlooked by conventional scientific research. Ninety interviews were conducted with riverine people in the vicinity of Anavilhanas National Park, Tapajós–Arapiuns Extractive Reserve and Tapajós National Forest in the Brazilian Amazon, with the aim to increase knowledge of the feeding habits of the Amazonian manatee Trichechus inunguis and evaluate its conservation status in contrasting protected areas. In Anavilhanas respondents identified 31 plant species consumed by the manatee, of which vines had the highest cognitive salience index value (the summed importance of each plant species), even though they are available to manatees only during the high-water season. In the Tapajós region 37 plant species were identified, with submerged species with floating leaves being the main component of the manatee's diet. Although hunting has declined it still occurs in Anavilhanas, which is susceptible to environmental crimes because of its proximity to urban centres. Manatee hunting seems to be infrequent in the Tapajós region, having little impact on the population. Given the broad knowledge within the local community about the Amazonian manatee, involvement of riverine people in manatee conservation activities is fundamental for reducing threats and increasing conservation effectiveness.
Optimal Path Planning Satisfying Complex Task Requirement in Uncertain Environment

Published: April 2019

SummaryRobots often need to accomplish some complex tasks such as surveillance, response and obstacle avoidance. In this paper, a dynamic search method is proposed to generate optimal robot trajectories satisfying complex task requirement in uncertain environment. The LTL-A* algorithm is presented to generate a global optimal path and the A* algorithm is provided to modify the global optimal path. The task is specified by a linear temporal logic (LTL) formula, and a weighted transition system according to the known information in uncertain environment is modeled to describe the robot motion. Subsequently, a product automaton is constructed by combining the transition system with the task requirement. Based on the product automaton, the LTL-A* algorithm is proposed to generate a global optimal path. The local path planning based on the A* algorithm is employed to deal with the environment change during the process of tracking the global optimal path for the robot. The results of the simulation and experiments show that the proposed method can not only meet the complex task requirement in uncertain environment but also improve the search efficiency.
Digital Media Experiments in China: “Revolutionizing” Persuasion under Xi Jinping
Authors: Repnikova Maria , Fang Kecheng 
Published: April 2019

AbstractWith the rapid decline of traditional media in China, the party-state faces the growing challenge of shaping public opinion online. This article engages with one response to this challenge – a state-sanctioned digital media experiment aimed at creating a new form of journalism that appeals to the public and helps to disseminate Party propaganda. We analyse the emergence of a national success story, Shanghai-based model media outlet Pengpai, and its diffusion across different regions. We argue that the synergy between local officials and media entrepreneurs has propelled Pengpai’s national fame. We further demonstrate that while there has been a cross-national attempt to diffuse this model, it has produced mixed results owing to a number of factors, including the superficial commitment of local officials and media professionals. These findings demonstrate that state-sanctioned decentralized experimentation can deliver unpredictable results in the sphere of media policy, and they further question the capacity of the party-state to effectively reinvent public persuasion in the digital age.
New records of mummified crabeater seals on islands bordering Admiralty Sound, Weddell Sea

Published: April 2019

AbstractNinety-six mummified crabeater seals discovered at Seymour Island (Isla Marambio) are reported. Each specimen was georeferenced, photographed and assigned to five different taphonomic states. Previous work stated that seals at Seymour Island get stranded inland around the breeding season. However, it is not clear if the species breeds in this area. The abundance of crabeater seals and the ice condition along Admiralty Sound (Estrecho Bouchard) were obtained by aerial surveys during spring (2015–17). It appears that the species uses the strait as a passage to breeding grounds. Under heavy ice conditions, the seals become stranded in the middle section of this strait and wander inland through a valley that represents the mouth of an ephemeral stream that ends at the pack ice level. This situation was observed in 2014 and 2015 when recently dead seals were found, evidencing that this natural trap is still active. Nonetheless, in 2016 and 2017, during an early breakup of Admiralty Sound, the seals that remained in the area were more numerous than in 2015 but they did not get stranded inland. This early breakup may encourage the seals to breed there in the presence of open water areas with ice floes.
