Accessing Information Asymmetry in Peer-to-Peer Lending by Default Prediction from Investors’ Perspective
Authors: Wei Xinyuan , Yu Bo , Liu Yao
Published: June 2020

Recent a few years have witnessed the rapid expansion of the peer-to-peer lending marketplace. As a new field of investment and a novel channel of financing, it has drawn extensive attention throughout the world. Many investors have shown great enthusiasm for this field. However, investors are at the disadvantage of information asymmetry, which is a key issue in this marketplace that is unavoidable and can lead to moral hazard or adverse selection. In this paper, we propose an L 1 / 2 -regularized weighted logistic regression model for default prediction of peer-to-peer lending loans from investors’ perspective, which can reduce the impact of information asymmetry in the process of loan decision. Rather than solely focus on the accuracy of the prediction, we take into consideration the different risk preferences of different investors. We try to find a trade-off between the risk of losing principal and that of losing potential investment opportunities on the basis of investors’ risk preferences. Meanwhile, due to the nature of peer-to-peer lending loans, we add an L 1 / 2 -regularization term to reduce the chance of overfitting. Xu’s algorithm for L 1 / 2 -regularization problems is applied to solve our model. We perform training, in-sample test, and out-of-sample test with data from LendingClub. Numerical experiments demonstrate that regularization could enhance out-of-sample the area under the Precision–Recall curve (AUPRC). By applying the proposed model, the risk-averse investors could apply a higher penalty factor to lower the risk of losing principal at the cost of the loss of some potential investment opportunities according to their own risk preferences. This model can help investors reduce the impact of information asymmetry to a great extent.
Statistical Inference of the Lifetime Performance Index with the Log-Logistic Distribution Based on Progressive First-Failure-Censored Data
Authors: Xie Ying , Gui Wenhao
Published: June 2020

Estimating the accurate evaluation of product lifetime performance has always been a hot topic in manufacturing industry. This paper, based on the lifetime performance index, focuses on its evaluation when a lower specification limit is given. The progressive first-failure-censored data we discuss have a common log-logistic distribution. Both Bayesian and non-Bayesian method are studied. Bayes estimator of the parameters of the log-logistic distribution and the lifetime performance index are obtained using both the Lindley approximation and Monte Carlo Markov Chain methods under symmetric and asymmetric loss functions. As for interval estimation, we apply the maximum likelihood estimator to construct the asymptotic confidence intervals and the Metropolis–Hastings algorithm to establish the highest posterior density credible intervals. Moreover, we analyze a real data set for demonstrative purposes. In addition, different criteria for deciding the optimal censoring scheme have been studied.
An Integrated Multi-Criteria Approach for Planning Railway Passenger Transport in the Case of Uncertainty
Authors: Stoilova Svetla
Published: June 2020

The aim of this study is to elaborate on an integrated approach for transport planning in railway passenger transport in the case of uncertainty. The methodology consists of four stages. In the first stage, the parameters of a multi-criteria model in the case of uncertainty were determined. This includes defining the criteria for selection of a transport plan; formulation of the alternatives of the transport plan; formulation of the strategies and probability variants of passenger flow variation for each strategy. In the second stage, the weights of the probability variants of the strategies for change in passenger flow were determined using the analytic hierarchy process (AHP) method. The alternatives of the transport plan were ranked by applying the sequential interactive modeling for urban systems (SIMUS) method based on linear programming. The results for the values of the criterion of ranking obtained through the SIMUS method and the weights of the variants of passenger flow variation calculated with the AHP method were used as input in the expected values in the decision tree. The selection of a suitable alternative in the case of uncertainty was conducted in the third stage by applying the decision tree method. In the fourth stage, verification of the results was made using Laplace’s criterion and Hurwitz’s criterion. The integrated multi-criteria approach was applied for Bulgaria’s railway network. The multi-criteria approach elaborated herein could be used for decision-making in the case of uncertainty about passenger flow; to investigate different strategies of passenger flow variation and to make decisions in case of instability of passenger flow or lack of sufficient travel data.

Published: June 2020

The aim of this paper is to study the stability of generalized Liouville–Caputo fractional differential equations in Hyers–Ulam sense. We show that three types of the generalized linear Liouville–Caputo fractional differential equations are Hyers–Ulam stable by a ρ -Laplace transform method. We establish existence and uniqueness of solutions to the Cauchy problem for the corresponding nonlinear equations with the help of fixed point theorems.
Production of Recombinant African Swine Fever Viruses: Speeding Up the Process
Authors: Rathakrishnan Anusyah , Moffat Katy , Reis Ana Luisa , Dixon Linda K.
Published: June 2020

African swine fever (ASF) is a devastating disease in pigs, with no vaccines for control. The genetic manipulation of African swine fever virus (ASFV) is often tedious and time consuming. Here, we describe a method to manipulate the virus genome to produce gene deletion viruses in a much-reduced time. This method combines the conventional homologous recombination with fluorescent-activated cells sorting (FACS), to isolate and purify viruses expressing fluorescent reporter genes. With three rounds of single cell isolation via FACS and two rounds of limiting dilution, we deleted two additional genes, EP153R and EP402R, from Benin 97/1 ASFV lacking the DP148R gene. By combining different fluorescent markers, this method has the potential to greatly facilitate studies on understanding ASFV gene functions and develop candidate live-attenuated vaccines.
Effects of Harmful Blooms of Large-Sized and Colonial Cyanobacteria on Aquatic Food Webs
Authors: Moustaka-Gouni Maria , Sommer Ulrich
Published: June 2020

Cyanobacterial blooms are the most important and best studied type of harmful algal blooms in fresh waters and brackish coastal seas. We here review how and to which extent they resist grazing by zooplankton, how zooplankton responds to cyanobacterial blooms and how these effects are further transmitted to fish. Size, toxicity and poor nutritional value are widespread mechanisms of grazing defense by cyanobacteria. In some cases, defenses are inducible, in some they are obligate. However, to some extent zooplankton overcome grazing resistance, partly after evolutionary adaptation. Cyanotoxins are also harmful to fish and may cause fish kills. However, some fish species feed on Cyanobacteria, are able to reduce their abundance, and grow on a cyanobacterial diet. While reduced edibility for crustacean zooplankton tends to elongate the food chain from primary producers to fish, direct feeding by fish tends to shorten it. The few available comparative studies relating fish yield to nutrients or phytoplankton provide no indication that cyanobacteria should reduce the ratio fish production: primary production.
Flow–Sediment Turbulent Ejections: Interaction between Surface and Subsurface Flow in Gravel-Bed Contaminated by Fine Sediment
Authors: N. Bustamante-Penagos , Y. Niño
Published: June 2020

Several researchers have studied turbulent structures, such as ejections, sweeps, and outwards and inwards interactions in flumes, where the streamwise velocity dominates over vertical and transversal velocities. However, this research presents an experimental study in which there are ejections associated with the interchange between surface and subsurface water, where the vertical velocity dominates over the streamwise component. The experiment is related to a surface alluvial stream that is polluted with fine sediment, which is percolated into the bed. The subsurface flow is modified by a lower permeability associated with the fine sediment and emerges to the surface current. Quasi-steady ejections are produced that drag fine sediment into the surface flow. Particle image velocimetry (PIV) measured the velocity field before and after the ejection. The velocity data were analyzed by scatter plots, power spectra, and wavelet analysis of turbulent fluctuations, finding changes in the distribution of turbulence interactions with and without the presence of fine deposits. The flow sediment ejection changes the patterns of turbulent structures and the distribution of the turbulence interactions that have been reported in open channels without subsurface flows.
Monthly Precipitation Forecasting in the Han River Basin, South Korea, Using Large-Scale Teleconnections and Multiple Regression Models
Authors: Kim Chul-Gyum , Lee Jeongwoo , Lee Jeong Eun , Kim Nam Won , Kim Hyeonjun
Published: June 2020

In this study, long-term precipitation forecasting models capable of reflecting constantly changing climate characteristics and providing forecasts for up to 12 months in advance were developed using lagged correlations with global and local climate indices. These models were applied to predict monthly precipitation in the Han River basin, South Korea. Based on the lead month of forecast, 10 climate indices with high correlations were selected and combined to construct four-variable multiple regression models for monthly precipitation forecasting. The forecast results for the analytical period (2010–2019) showed that predictability was low for some summer seasons but satisfactory for other seasons and long periods. In the goodness-of-fit test results, the Nash–Sutcliffe efficiency (0.48–0.57) and the ratio of the root mean square error to the standard deviation of the observation (0.66–0.72) were evaluated to be satisfactory while the percent bias (9.4–15.5%) was evaluated to be between very good and good. Due to the nature of the statistical models, however, the predictability is highly likely to be reduced if climate phenomena that are different from the statistical characteristics of the past appear in the forecast targets or predictors. The forecast results were also presented as tercile probability information (below normal, normal, above normal) through a comparison with the observation data of the past 30 years. The results are expected to be utilized as useful forecast information in practice if the predictability for some periods is improved.
The Effects of Rainfall Intensities and Duration on SCS-CN Model Parameters under Simulated Rainfall
Authors: Wang Xiaoxian , Bi Huaxing
Published: June 2020

The Soil Conservation Service curve number (SCS-CN) method has been widely used in rainfall-runoff modelling; however, the direct effects of rainfall intensities and duration, which are major factors in hydrological engineering design, on its parameters (initial abstraction ratio (λ) and potential maximum storage (S), the latter is transformed into curve number (CN)) have seldom been studied. In this study, we chose simulated rainfall experiments on runoff plots (30 mm/h, 180 min; 60 mm/h, 90 min; 90 mm/h, 60 min) to obtain synchronized rainfall-runoff data and calculated the parameters using general model fitting and event analysis methods every ten minutes throughout the duration. The results indicate that the parameters changed with rainfall intensities and duration. S decreased as the rainfall intensities increased. Under the same rainfall intensity, the S increased with the duration overall. The corresponding λ changed with rainfall intensities and duration, and has no obvious relationship under different rainfall intensities. Initial abstraction in the event analysis method is the same as the actual situation and we chose these parameters obtained with the event analysis method as our selected parameters. These selected parameters and the parameters obtained using Fu et al.’s method which was based on the standardized procedure in NEH-630 were evaluated by the Nash–Sutcliffe efficiency (NSE), the percentage deviation coefficient (PBIAS), and the ratio of the root mean square error to the standard deviation of measured data (RSR). The results show that the statistics for the selected parameters satisfied the evaluating standard, and have a better value, while the statistics for the parameters obtained by Fu et al.’s method declined as the rainfall intensity increased, and PBAIS was out of the standard range under 90 mm/h rainfall intensity condition. This indicates that the rainfall intensities and duration have important effects on the parameters of the model, and the parameters vary dynamically with the rainfall intensity and duration. These results could be useful for hydrological design in which engineers consider the return period (i.e., rainfall intensities and duration).
TASKS OF MODERN EDUCATION IN THE PERSPECTIVE OF GLOBAL DEVELOPMENT TRENDS
Authors: Podoliakina Olga
Published: June 2020

A successful example of the integration of modern science into the educational process is the activity of the Club of Rome, the materials of each report of which become an important component of the educational “product” of many higher educational institutions, and especially those which are providing adult education.
The perception of the ideas of the Club depended largely on their inclusion in the agenda – political, economic, cultural etc. The quality of such perception depends on the level of competence of those who perceive and on whether they evaluate the forecasts of the Club only as information, or take them as a value. The value perception of predictions of social development enables them to form principles of personal behavior and methodology for the perception and transformation of the social and natural environment. The combination of information and value influence on the individual can be done in different ways, but one of the most effective is the educational means of influence.
Indirectly the participants in the activities of the Roman Club have become more than one generation of globalized humanity – since 1968, one can count the life of the third generation.

A través de la revisión documental, con base al enfoque cualitativo e interpretativo, el presente trabajo pretende realizar un recuento de los principales términos utilizados actualmente en el manejo de la información: disinformation, misinformation, posverdad y fakenews. Términos que evidencian la relevancia que ha adquirido la información obtenida a través de las redes sociales y que, en consecuencia, generan un desorden informativo. Esto es posible debido al crecimiento exponencial de la información en un entorno supeditado al desarrollo de las tecnologías de la información y comunicación (TIC), donde constantemente se pone en tela de juicio su veracidad y como resultado se pierde su valor y se hace cada vez más difícil la elección de información veraz y correcta. Los resultados permiten realizar precisiones conceptuales, identificar las relaciones existentes de similitud, diferencias y yuxtaposición en cada uno de los términos que han surgido en este contexto con algunos ejemplos.

Cretaceous and Cenozoic dinoflagellate cysts and other palynomorphs from the western and eastern margins of the Labrador–Baffin Seaway
Authors: Fensome Robert A. , Nøhr-Hansen Henrik , Williams Graham L.
Published: June 2020

New palynological analysis of samples from 13 offshore wells on the Canadian Margin and six wells on the West Greenland Margin has led to a new event biostratigraphic framework for Cretaceous–Cenozoic strata of the Labrador Sea – Davis Strait – Baffin Bay (Labrador–Baffin Seaway) region. This framework is based on about 150 dinoflagellate cyst taxa and 30 acritarch, algal, fungal and plant microfossil (mostly miospore) taxa. In the systematics we include three new genera of dinocysts (Scalenodinium, Simplicidinium and Taurodinium), 16 new species of dinocysts (Chiropteridium gilbertii, Chytroeisphaeridia hadra, Cleistosphaeridium elegantulum, Cleistosphaeridium palmatum, Dapsilidinium pseudoinsertum, Deflandrea borealis, Evittosphaerula? foraminosa, Ginginodinium? flexidentatum, Hystrichosphaeridium quadratum, Hystrichostrogylon digitus, Impletosphaeridium apodastum, Scalenodinium scalenum, Surculosphaeridium convocatum, Talladinium pellis, Taurodinium granulatum and Trithyrodinium? conservatum), four emendations of dinocyst genera (Alterbidinium, Chatangiella, Chiropteridium and Surculosphaeridium), six new combinations for dinocyst species (Alterbidinium biaperturum, Deflandrea majae, Kleithriasphaeridium mantellii, Simplicidinium insolitum, Spongodinium grossum, Spongodinium obscurum), one new acritarch species (Fromea quadrangularis), one new miospore species (Baculatisporites crenulatus) and one new combination for miospores (Tiliaepollenites crassipites). Most of the taxa included provide age information, almost exclusively last occurrences (range ‘tops’), but some are useful mainly for environmental interpretations. Collectively, they provide a powerful tool for helping to establish the geological history of the Labrador–Baffin Seaway.
Descriptive text to Geological map of Greenland, 1:500 000, Dove Bugt, Sheet 10
Authors: Henriksen Niels , Higgins A.K.
Published: June 2020

The Dove Bugt 1:500 000 scale geological map sheet covers a segment of the East Greenland Caledonian orogen extending between latitudes 75°–78°N and longitudes 16°–29°W. The region was mapped in the summers of 1988–1990 as part of a regional Survey mapping programme, and the map sheet was printed in 1997.

The region covered by the Dove Bugt map sheet is dominated by Palaeoproterozoic gneiss complexes, with smaller amounts of Mesoproterozoic and Neoproterozoic metasedimentary rocks, and isolated strips of Palaeoproterozoic and Lower Palaeozoic sedimentary rocks. All these rock units have been reworked to a varying degree during the Caledonian orogeny. Post-Caledonian sedimentary rocks occur in the south-east corner of the map sheet area and as narrow, fault-bounded enclaves elsewhere, while Palaeogene basaltic lavas and sills crop out on the island of Shannon.

The rocks of the Caledonian orogen form a number of major thrust domains. The most extensive and structurally lowest is the Nørreland thrust sheet which is characterised by lenses and layers of medium-temperature, high-pressure eclogites. The Western thrust belt occupies a broad zone of eastern Dronning Louise Land that comprises Palaeoproterozoic gneiss complexes interleaved with Palaeoproterozoic and Palaeozoic metasedimentary rocks. This thrust domain is separated from the foreland rocks of western Dronning Louise Land by the Imbricate thrust zone. In the south-west part of the map sheet the highest structural domain, the Hagar Bjerg thrust sheet comprises three rock sequences: crystalline gneisses, the Mesoproterozoic Smallefjord sequence and the Neoproterozoic Eleonore Bay Supergroup.

The crystalline gneiss complexes that dominate the map sheet area and make up a significant proportion of the different Caledonian thrust domains have all yielded protolith ages of c. 2 Ga. They are attributed to a major period of crust formation in the Palaeoproterozoic. The gneisses have been variably affected by Caledonian deformation and metamorphism.

Między edukacją a indoktrynacją Dobra rodziny na łamach czasopism kobiecych w Polsce lat 70.
Na przykładzie czasopism „Przyjaciółka” i „Kobieta i Życie”
Authors: Doniec Renata
Published: June 2020

Celem artykułu jest pokazanie deformacji rodziny i jej dóbr dokonywanych na łamach dwóch najbardziej popularnych czasopism kobiecych PRL – „Przyjaciółka” i „Kobieta i Życie” w ramach prowadzonej przez nie działalności społeczno-wychowawczej. Oficjalnie polegać miała ona na podnoszeniu świadomości małżeńskiej, rodzicielskiej i społecznej kobiet, co w odniesieniu do wybranych aspektów życia codziennego miało miejsce, ale oprócz tego prowadzono w nich zdecydowaną indoktrynację ideologiczną, która stosując określone mechanizmy propagandowe dokonywała redukcji i wypaczeń znaczenia wielu wartości rodzinnych, dokonując przy tym niebezpiecznych manipulacji intelektualnych i emocjonalnych. Biorąc pod uwagę niezwykłą popularność tych czasopism i ponad 40-letni okres ich obecności na rynku, można obawiać się negatywnych skutków ich oddziaływań na świadomość małżeńską-rodzinną całego pokolenia polskich kobiet-czytelniczek tej prasy. Prezentowany tekst stanowi swoistą kontynuację badań A. Kłoskowskiej i F. Adamskiego, którzy w różnych okresach PRL starali się odczytywać zakres upolitycznienia przekazywanych w nich treści. Obecność cenzury uniemożliwiała jednak pełne pokazanie tego zjawiska. Obecne badanie tych samych zagadnień, ale w innych uwarunkowaniach historycznych, dowodzi możliwości odkrywania nowych faktów, istotnych dla lepszego zrozumienia dzisiejszej rzeczywistości. Badaniami objęto oprócz prac powyższych autorów, 104 numery czasopism „Przyjaciółka” i „Kobieta i Życie” z 1975 r., które poddano analizie frekwencyjno-tematycznej w ramach metody badania zawartości mediów. Nawiązując do koncepcji modelu komunikacyjnego H. Lasswella, sformułowano trzy zasadnicze problemy badawcze (i odpowiadające im pytania szczegółowe) nastawione na poznanie: 1) przekazywanych treści (ich sensu i znaczeń), 2) treści pomijanych, 3) cech dyskursu, 4) mechanizmów przekazu. Występowanie działań indoktrynacyjno-propagandowych określano na podstawie ustalonych wskaźników (kryteriów). Teoretycznym odniesieniem dla badań była komunistyczna koncepcja rodziny w ujęciu K. Marksa, F. Engelsa i W. Lenina.

Desde 1956, o escritor empenhou-se em valorizar a evolução e o lugar daquele movimento literário na literatura portuguesa de novecentos. Por meio da escrita ensaística, Namora responde ao ocaso neo-realista mas também à hostilidade crescente do campo literário português àquele movimento, pondo em causa muitos lugares comuns da crítica e um conceito linear e monológico de tempo histórico em literatura.
Comparative Analysis Method of Work, Time and Cost of Concrete Spun Pile Work with Bored Pile On Construction of the Light Rail Transit (LRT)
Authors: Lutfiansyah Yopi , Akhsan Muhammad
Published: June 2020

Building construction consists of two parts, namely the upper building and lower building. The upper building transmits forces to the lower building, which then from the lower building is channeled to the supporting soil. Pile foundation is a part of the lower structure that is used to receive and distribute the load from the upper structure to the supporting soil which is located at a certain depth determined by the results of the soil investigation. Piles are used as building foundations if the soil under the building base does not have enough bearing capacity to carry the weight of the building working on it. The stake used in this comparison is the Concrete Spun Pile and Bored Pile foundation. The results of the study show that the Bored pile method is slightly more complicated than the Concrete spun pile method. In terms of time required for the Concrete spun work is 6 hours, while for Bored piles per point is 9 hours assuming the work is 3 months In terms of the cost of foundation work of 1000mm diameter and 30m depth using the Concrete spun pile method is Rp. 13,704,241,634.10 for 156 points. whereas for the Bored pile method with a diameter of 1200mm and a depth of 30m is Rp. 14,242,797,932.85 for 78 points. So the foundation work with the Concrete spun pile method is more effective and efficient than the Bored pile method based on the method of implementation, time and cost.

The global increasing alertness of the environmental and health problems linked to the use of mineral based metal cutting fluids in machining is lead industry to develop alternative fluid. The fluid should be environmentally friendly and sustainable like vegetable oil with suspended nanoparticle. The low thermal conductivity of cutting fluids of natural based oil requires the addition of nanoparticles. The most common nanoparticle that suitable to be added to cutting fluid are non-metals, carbide, oxide, Carbon Nano Tubes (CNTs) and metal nitrides. In this paper, a comparison had made of dry machining and machining with cutting coolant oil, sunflower oil+MoS2, Sunflower, oil Graphene. The study concludes that, the addition of such minerals to the cutting fluids increased the thermal conductivity of cutting fluids.

The environmental concerns are on the rise these days. Car, bus, and truck air pollutants can worsen respiratory diseases and cause asthma attacks. Transportation is responsible for airborne carbon monoxide at more than 50 per cent. At present, the emissions of the vehicle is checked with the aid of pollution control stations built in some cities only when the fitness certificate (FC) is obtained from the RTO office. In case of private cars, the health certificates are valid for 15 years and every 5 years thereafter. In case of Transport Vehicles, the fitness certificate is given for a new vehicle for 2 years and then extended each year. Under this process, we cannot detect emissions caused if the vehicle has been repaired until FC. Using IoT Technology, this project aims to monitor and alert air pollution on roads and to track vehicles that cause emissions above a given threshold by connecting the Global System of Mobile Communications Network to the cloud. This also concentrates on avoiding the accidents caused by vehicle-generated carbon monoxide gas using MQ7 Gas sensor.

The term Diabetic retinopathy is the serious issue that is caused by the diabetes, which affects the eyes that may lead to blindness. DR takes place due to damaged arteries and veins that are a part of the fundus of the eye. Although DR can be prevalent now days, its prevention remains challenging. Visual analysis of the funds and consideration of colour photographs Ophthalmologists directly examine the existence and severity of DR. This process is expensive as well as time consuming as there are huge number of diabetes affected people worldwide. The automatic Diabetic Retinopathy system is expanded to predict various related diseases that are analysed. The proposed methodology uses EYEPACS dataset that consists on 35,126 fundus images. These images are pre-processed and sent to neural network that detects type of DR. CNN detects clusters of pixels that are damaged in the macula region and in turn evaluates the overall damaged area in the macula from the retinal images. The retinal fundus images present structural and impulsive noise.

In the novel times, with the surge in use of power electronics, power quality with system efficiency is playing a symbolic role for the advancement of electric supply. The fundamental purpose of the electric utility is to provide a sinusoidal voltage at constant magnitude throughout the system. This objective is convoluted because of the loads present in the system which produce harmonic currents. Due to these harmonic currents, distorted voltages and currents are carried out which affect the reliability and efficiency of the system in several ways. The sinusoidal waveform produced by electric utilities is distorted due to harmonics and increased use of non-linear loads. The deterioration of the power quality and reliability of the power system is due to the presence of these harmonics in the power system. Hence, we need a proper analytical approach to study, classify and characterize the harmonics present in the system and develop a suitable and effective mitigation method to reduce the harmonics in the power system to standard limits of harmonics prescribed by the IEEE and IEC standards. The study of the level of harmonics present in the system, their causes and effects are known as harmonic analysis or harmonics study. Based on the observations of harmonic analysis we develop mitigation techniques to reduce these harmonics. One such method is the implementation of filters. By implementing harmonic filters, we mitigate the harmonics present in the system by providing a low impedance path. The methodological procedure behind effective design and implementation of filters is achieved by performing load flow analysis to obtain the system data and harmonic analysis to obtain data of harmonics present in the system. Based on the data obtained, the type of filter and the optimal placement of filter is decided to mitigate the harmonics. The mitigation of harmonics can report significant benefits for industries, data centers, etc. in terms of overall installation cost and protection against interruptions and equipment faults in the power system. The overall process of Harmonic analysis and mitigation techniques are performed using Mi-Power software.
