Abstract
The diet of myrmecophagous mammals is usually studied by investigating the chitinous remains of termites and ants obtained from stomachs, guts, and faeces; however, this process is time and labour intensive. Moreover, faeces of obligate myrmecophagous mammals contain other materials such as soil, sand, rocks, and plant matter, which hinder the accurate and efficient identification of faeces’ contents; this makes estimating the biomass of each prey species difficult. This study tested non-filtering and filtering faecal analysis procedures and compared their identification accuracy and efficiency in the analysis of Formosan pangolin Manis pentadactyla pentadactyla faeces. In the non-filtering procedure, 1 g of dried faeces was distributed over an area greater than 360 cm2 to be able to see most ant capsules and termite mandibles. In the filtering procedure, 0.5 cm3 of filtered chitinous remains of termites and ants was spread over a 45 cm2 area to obtain a high resolution of the diet composition. The filtering procedure can sieve out insect remains from the debris, which facilitates further identification of the insect chitin. Using the two proposed faecal analysis procedures, the prey species composition and the number of prey remains could be obtained. Our results provide a quantitative method to evaluate the diversity of wild pangolin’s diets for determining their ecological requirements and developing in-situ and ex-situ conservation plans.
Persistence, Temporal Extension, and Transdurantism
Authors: Daniels Paul R. 
Published: April 2019

AbstractI explicate and defend a non-standard theory of persistence, which I calltransdurantism. In short, transdurantism is the view is that objects persist by being temporally extended simples. Transdurantism is sometime misrepresented as a version of endurantism. Other times, transdurantism is misrepresented as a version of perdurantism. But I argue transdurantism must be disambiguated from perdurantism and endurantism—when endurantism, perdurantism, and transdurantism are properly construed, transdurantism stands apart from the other theories of persistence and we can better understand the distinct burdens they each bear. I also argue that the transdurantist is capable of handling several key problems found in the persistence literature at least as well as her rivals, but she does face her own unique challenges.

Abstract
The objectives of the study were to assess the inter-relationship between growth, yield, nutritional and anti-nutritional responses of thirteen tannia (Xanthosoma sagittifolium L.) accessions to planting date (May, June and July) in the humid tropics. Tannia corms and leaves are veritable sources of dietary fibre and starch, also essential minerals and vitamins; hence its value for security and as a cash crop for people in the humid tropics. A two-year 13-genotype × 3 planting date factorial arranged rain-fed field experiment in randomized complete block design with three replications was carried out during the 2014 and 2015 cropping seasons at Michael Okpara University of Agriculture, Umudike, Nigeria. The results indicated that planting date and accession influenced growth and yield of tannia, an indication of differential responses of the thirteen accessions to the planting dates (May, June and July). The results suggest that May is the most appropriate planting date; accessions planted during this month had the highest yields. The interaction between planting date and tannia accession was significant for some traits (number of leaves per plant and cormel weight per plant) in both years and significant for plant height, pseudo-circumference and corm weight (2014); leaf area and tannia yield (2015). The correlation analysis showed good selection characters in plant height, pseudo-stem circumference, leaf area, number of leaves per plant, corm weight, corm circumference, cormel weight and cormel circumference for high yielding varieties, while nutritional analysis (crude protein, carbohydrate, phosphorus, potassium, calcium, tannin and oxalate) exhibited lower concentrations in processed corms relative to unprocessed. The corm yield of the tannia accessions ranged from 1.49 to 13.48 Mt.ha−1 in 2014 and 2.72 to 8.50 Mt.ha−1 in 2015 and best four accessions judged by interaction between tannia accession and date of planting was 13 (Ikaro) > 12 (Idoani) > 3 (Ehor) > 10 (Idasen) in May 2014 compared to accessions 6 (Ewu) >10 (Idasen) > 12 (Idoani) > 1 (Ikpoba) planted in June 2015. The differences in sequence suggest that both environment and genetic constitution contribute to Tannia yield.
Risk as a Predictor of Online Competitive Information Acquisition
Authors: Raban Daphne Ruth , Koren Lior 
Published: April 2019

AbstractThis study set out to investigate how personal user traits and behavior and information cues influence the acquisition of online information for actionable decisions. The relationship between personal traits (risk propensity and individual information absorptive capacity), behavioral factors (perceived risk and willingness-to-pay) and informational cues (scenario risk level) was examined by conducting an experiment with 125 mid-level managers. Participants were exposed to high- and low-risk scenarios, given the opportunity to consume free and fee-based competitive information sources, and asked to make a managerial decision. Results of the Willingness-to-Pay (WTP) for information sources indicate: (i) a significant correlation between the perceived risk and WTP, (ii) a significant correlation between the perceived risk and the number of competitive intelligence information items bought, (iii) individual absorptive capacity has high internal reliability, and (iv) investment risk propensity and individual information absorptive capacity did not influence WTP or willingness-to-consume competitive intelligence information. Informational cues rather than personal traits impact decision makers' WTP and willingness to-consume competitive intelligence information. This suggests that best practices should be developed for the use of online information sources in decision-making calibrated to the risk level. Risk level indication may also aid to avoid biases stemming from under- or overuse of information.

Authors: Tian Manwen , Yan Shurong , Tian Xiaoxiao 
Published: April 2019

Abstract
There are many non-probability factors affecting financial markets and the return on risk assets is fuzzy and uncertain. The authors propose new risk measurement methods to describe or measure the real investment risks. Currently many scholars are studying fuzzy asset portfolios. Based on previous research and in view of the threshold value constraint and entropy constraint of transaction costs and transaction volume, the multiple-period mean value -mean absolute deviation investment portfolio optimization model was proposed on a trial basis. This model focuses on a dynamic optimization problem with path dependence; solving using the discrete approximate iteration method certifies the algorithm is convergent. Upon the empirical research on 30 weighted stocks selected from Shanghai Stock Exchange and Shenzhen Stock Exchange, a multi-period investment portfolio optimum strategy was designed. Through the empirical research, it can be found that the multi-period investments dynamic optimization model has linear convergence and is more effective. This is of great value for investors to develop a multi-stage fuzzy portfolio investment strategy.

Published: April 2019

Abstract
To solve the problem of multi-objective performance optimization based on ant colony algorithm, a multi-objective performance optimization method of ORC cycle based on an improved ant colony algorithm is proposed. Through the analysis of the ORC cycle system, the thermodynamic model of the ORC system is constructed. Based on the first law of thermodynamics and the second law of thermodynamics, the ORC system evaluation model is established in a MATLAB environment. The sensitivity analysis of the system is carried out by using the system performance evaluation index, and the optimal working parameter combination is obtained. The ant colony algorithm is used to optimize the performance of the ORC system and obtain the optimal solution. Experimental results show that the proposed multi-objective performance optimization method based on the ant colony algorithm for the ORC cycle needs a shorter optimization time and has a higher optimization efficiency.

Abstract
In this study, a multi-objective design optimization method based on a radial basis function (RBF) model was applied to minimize the volumetric shrinkage and warpage of hip liners as an injection-molded biomedical part. The hip liners included an ultrahigh molecular weight polyethylene (UHMWPE) liner and UHMWPE reinforced with a nano-hydroxyapatite (nHA) liner. The shrinkage and warpage values of the hip liners were generated by simulation of the injection molding process using Autodesk Moldflow. The RBF model was used to build an approximate function relationship between the objectives and the process parameters. The process parameters, including mold temperature, melt temperature, injection time, packing time, packing pressure, coolant temperature, and type of liner, were surveyed to find the interaction effects of them on the shrinkage and warpage of the liners. The results indicated that the addition of nHA helps the liners to obtain more dimensional stability. The model was validated by the k-fold cross validation technique. Finally, the model revealed the optimal process conditions to achieve the minimized shrinkage and warpage simultaneously for various weights.
Role of chemical additives and their rheological properties in enhanced oil recovery
Authors: Machale Jinesh , Majumder Subrata Kumar , Ghosh Pallab , Sen Tushar Kanti 
Published: April 2019

Abstract
A significant amount of oil (i.e. 60–70%) remains trapped in reservoirs after the conventional primary and secondary methods of oil recovery. Enhanced oil recovery (EOR) methods are therefore necessary to recover the major fraction of unrecovered trapped oil from reservoirs to meet the present-day energy demands. The chemical EOR method is one of the promising methods where various chemical additives, such as alkalis, surfactants, polymer, and the combination of all alkali–surfactant–polymer (ASP) or surfactant–polymer (SP) solutions, are injected into the reservoir to improve the displacement and sweep efficiency. Every oil field has different conditions, which imposes new challenges toward alternative but more effective EOR techniques. Among such attractive alternative additives are polymeric surfactants, natural surfactants, nanoparticles, and self-assembled polymer systems for EOR. In this paper, water-soluble chemical additives such as alkalis, surfactants, polymer, and ASP or SP solution for chemical EOR are highlighted. This review also discusses the concepts and techniques related to the chemical methods of EOR, and highlights the rheological properties of the chemicals involved in the efficiency of EOR methods.
N2 amplitude modulation across the antisocial spectrum: a meta-analysis

Published: April 2019

Abstract
Despite the accumulated knowledge on antisocial behavior and the positive event-related potential peaking around 300 ms (P3), less is known about the preceding negative electrophysiological response around 200 ms (N2). A systematic search of the literature was conducted to analyze the N2 modulation across the antisocial spectrum. Thirty-seven studies (n = 1199) were retrieved to the quantitative analysis. Reduced N2 amplitudes were found in the more severe antisocial manifestations (violent behavior and antisocial personality disorder), which is consistent with previous findings on P3 alterations and N2 reduced amplitudes in externalizing disorders. Findings on psychopathy were mixed, also in accordance with previous P3 results. From a dimensional lens, this supports the heterogeneity of the psychopathic personality structure: impulsivity features are a closer attribute of antisocial behavior and thus may be associated with N2 reduction, while adaptive psychopathic traits may be associated with intact (or even increased) N2 amplitude. The increased N2 amplitudes observed in impulsive behavior challenge, however, the previous meta-analytic findings. As most of the studies on impulsivity include subclinical samples, it leads to the hypothesis that some compensatory mechanisms can still occur at a subclinical level, reflecting the need for heightened allocation of brain resources to yield similar performances. Importantly, inhibition was the core deficit to explain N2 blunted amplitudes, alongside with deficits in the frontal brain region. From our findings, the reduction in P3 amplitude across the antisocial spectrum may be detected in the previous N2 time window.

Published: April 2019

Abstract
Genome-wide sequencing enables evaluation of associations between traits and combinations of variants in genes and pathways. But such evaluation requires multi-locus association tests with good power, regardless of the variant and trait characteristics. And since analyzing families may yield more power than analyzing unrelated individuals, we need multi-locus tests applicable to both related and unrelated individuals. Here we describe such tests, and we introduce SKAT-X, a new test statistic that uses genome-wide data obtained from related or unrelated subjects to optimize power for the specific data at hand. Simulations show that: a) SKAT-X performs well regardless of variant and trait characteristics; and b) for binary traits, analyzing affected relatives brings more power than analyzing unrelated individuals, consistent with previous findings for single-locus tests. We illustrate the methods by application to rare unclassified missense variants in the tumor suppressor gene BRCA2, as applied to combined data from prostate cancer families and unrelated prostate cancer cases and controls in the Multi-ethnic Cohort (MEC). The methods can be implemented using open-source code for public use as the R-package GATARS (Genetic Association Tests for Arbitrarily Related Subjects) <https://gailg.github.io/gatars/>.
Semeiotic completeness in the theory of signs
Authors: Pietarinen Ahti-Veikko 
Published: April 2019

AbstractPeirce aspired for the completeness of his logiccumthe theory of signs in his 1903 Lowell Lectures and other late manuscripts. Semeiotic completeness states that everything that is a consequence in logical critic is derivable in speculative grammar. The present paper exposes the reasons why Peirce would fall short of establishing semeiotic completeness and thus why he would not continue seeking a perfect match between the theories of grammar and critic. Some alternative notions are then proposed.
Adsorption Kinetics of Nitrogen Molecules on Size-Selected Silver Cluster Cations

Published: April 2019

Abstract
We present adsorption processes of dinitrogen on size-selected silver cluster cations, Ag
n

+ (n = 1–10), studied by kinetics measurement using an ion trap. The cluster ions showed sequential adsorption of N2 molecules when the ion trap was cooled down to 105 K, excluding n = 8 and 9 that were exceptionally inactive at this temperature. Termolecular rate coefficients of each adsorption step are determined by analyzing time-dependent changes in the reactant and product ion signals. The first-step rate coefficients were found to increase exponentially from n = 1 to 7 due to increased internal degrees of freedom at larger sizes, which are favorable for accommodating the adsorption energy in a free cluster. In contrast, the adsorption rate turned to decrease for n > 7 due to weaker binding of dinitrogen as revealed by density-functional-theory (DFT) calculation. Adsorption sites on Ag
n

+ are further discussed on the basis of the maximum number of adsorbing N2 molecules observed in the experiment.

Authors: Da Bo , Yu Hongfa , Ma Haiyan , Wu Zhangyu 
Published: April 2019

Abstract
The use of electrochemical impedance spectroscopy (EIS) method, Nyquist plots, and Bode impedance module plots of coral aggregate seawater concrete (CASC) at different exposure times in a seawater immersion environment was tested. The most suitable equivalent electric circuit (EEC) for fitting reinforcement corrosion of CASC in a seawater immersion environment was investigated. The reinforcement corrosion electrochemical parameters were calculated. The factors affecting reinforcement corrosion of CASC were researched. The results showed that in order to reduce reinforcement corrosion risk, the concrete cover thickness should be thicker than 5.5 cm. As exposure time increased, the decrease rate of anticorrosion effectiveness for the calcium nitrate inhibitor was higher than that for the amino alcohol inhibitor. Corrosion resistance would improve if the inhibitor was preabsorbed. Corrosion resistance of different types of reinforcements followed the rule: 2205 duplex stainless steel &gt; 316 stainless steel &gt; new organic coated steel &gt; zinc–chromium coated steel &gt; common steel.

Истернизация русской повседневности: история и современность

Цитирование: Ильин В.И. (2019) Истернизация русской повседневности: история и современность // Мир России. Т. 28. № 2. С. 25–41.DOI: 10.17323/1811-038X-2019-28-2-25-41
Процессы культурной диффузии как фактор развития русской повседневной культуры веками шли в форме вестернизации и истернизации, и почти на всех этапах русской истории, включая современный, доминировала вестернизация. При этом истернизация очень часто принимала парадоксальные формы вестернизации: 1) восточное влияние на русскую повседневную культуру часто оказывалось через западные страны; 2) из стран Востока импортировались товары, изначально появившиеся в западной культуре, но производимые в дальнейшем в восточных государствах. В отличие от вестернизации истернизация повседневности обычно не влекла за собой изменений структур образа жизни. Причина состояла в том, что импортируемые элементы восточной культуры были глубоко укоренены в качестве элементов цельной системы ментальности, в то время как вестернизация повседневности опиралась на удовлетворении естественных универсальных потребностей в физическом и духовном комфорте, благодаря чему она легко прививалась к любой культуре, порождая своеобразные глокальные гибриды. Восток внедрялся в Россию в двух формах: с одной стороны, это было прямое проникновение в пространство русской повседневности (от нашествия агрессоров до импорта товаров); с другой, Восток регулярно проявлялся в виде мифа, и эти ипостаси частично переплетались (миф стимулировал импорт, выступая инструментом «мягкой силы»). Целью данной статьи является концептуализация категории истернизации российской повседневности как сквозного процесса российской истории.
