Financing Gap and Implications for the Cultural Activity Sector
Authors:   Asia-Europe Perspective Association, Seo Eunsook , You Seung Dong
Published: June 2018

We can observe excess capital demands in the financial market for the creative industry that includes gaming, animation, character licensing, music, fashion, and broadcasting. The excess demands seem to arise from information asymmetries between capital demanders and capital providers. Capital market polices can be critical, as capital providers tend to take account only of collaterals that capital demanders provide. In the paper, we estimate the amount of an excess capital demand in the Korean creative industry. We adopt an estimate strategy by European Commission (2013) that studies capital financing GAPs for small and medium-sized enterprises. Using various scenarios, we provide several estimates; the estimates range from KRW 2.1 trillions to KRW 5.7 trillions. The estimated financing gap can deliver critical information for designing industry polices.
Price Spillover Effects across Natural Gas, Oil and Stock Markets in Korea, China and Japan
Authors:   Asia-Europe Perspective Association, Li Sha , Cho Hong Chong
Published: June 2018

Korea, Japan, and China are the most important importer in Asian LNG market and they import natural gas as LNG. With the price mechanism that LNG price is linked with oil price, they have mutual relationship with other countries. Different with the crude oil market, natural gas market is still under development. In this paper, we check the cointegrated situation with 3 countries importing price with the VAR(Vector Autoregressive) model and analyze the spillover effect in the formation of LNG importing price. We investigate price spillover effect on LNG, crude oil and markets price in Asian countries by the analysis of the linear VAR model with the LNG price as an independent variable, and the international oil price, stock market index in the 3 countries as an exogenous variable. The results show that Korean and Japanese gas prices are cointegrated with WTI oil prices, but Chinese natural gas market doesn’t show the same results compared with Korea and Japan. Moreover the Chinese LNG price has the negative relationship with Shanghai stock return and the WTI and the NYSE are no relationship with the Chinese LNG price. In Korea, LNG price has the positive relationship with the one-time lag of WTI but neither KOSPI or NYSE has the effect on the Korean LNG market. Japanese LNG price has the positive relationship with the one-time lag of WTI and one-time lag of NYSE although it has little relationship with NIKKEI index. These results support the price spillover from crude oil markets to LNG market, butlocal stock markets do not support the price spillover to LNG market in Korea, China and Japan. Japanese LNG importing price spillover to the stock market of Japan. The different results of price spillover effect could be explained by the pricing mechanism of LNG.
Due to regional segmentation and limited inter-continental natural gas trade, it is highly possible for each region to have different spillover effects. The results of this paper have at least two policy implications. First, since Korea and Japan have long history of importing LNG and spillover effect between two countries, they should try to diversify the importing countries and reduce the Asian premium price. Furthermore, China is still under the early phase of the importing natural gas and it need the preemptive policy to limit the natural gas price from rising through liberalization of natural gas market. The research is not free from the limitation what the results are only applied to Asian 3 countries and we will need to develop the expanded model for the generalization of the LNG price mechanism.
The Effects of House Price on Household Consumption
Authors:   Asia-Europe Perspective Association, Su-Min Jeon Su-Min Jeo , Kwon Sun-Hee
Published: June 2018

This study analyzes the short - term and long - term effects of home sale price and lease price on household consumption using quarterly data from 1990 to 2016.
In particular, we analyzed the effect of housing prices on household consumption by dividing the households into two groups of households with more than two employees, as well as households with workers, self-employed households, and income groups (low-income, middle-income and high-income families).
The main results of the empirical analysis are summarized as follows: Household consumption is affected by the change of home sale price and charter price in the long term compared to the short term. In households, compared to the self-employed households. In addition, households’ consumption of home prices (-0.44%) was much higher than that of households (+0.13%).
It is highly probable that the steep rise in home sales prices and the surge in rental prices after the global financial crisis have been a stumbling block to household consumption and delayed economic recovery.
Accordingly, it is necessary to make policy efforts to revitalize housing market transactions and stabilize rental prices.
The Effect of Participation Rate by Others on an Individual’s Charitable Behavior: The Role of Prominence of Group Identity
Authors:   Asia-Europe Perspective Association, Lee Seung Yun , Kim Jin Wook , Chung Heejeun , Kim Shomi
Published: June 2018

Charitable organizations often use the high participation rate of others to influence potential donors, with announcements such as “Nearly 70% of people who were asked to donate have contributed to the campaign.” For instance, pro-social messages, such as charity and volunteering campaigns, often use the participation rate of others to influence potential donors, with announcements such as “Nearly 70% of people who were asked to donate have contributed to the campaign” or “In the latest Canada Survey of Giving, 85% of Albertans reported having donated to a charity or nonprofit organization in 2007.” In the context of charitable behavior, the participation rate of others can be defined as one’s perception of how many others have been helping or donating in a specific predicament. Many participation-encouraging messages have been informed by the participation rate by others giving a donation. In this present research, we are interested in examining how the participation rate of others can influence an individual’s charitable behavior. In present research, we examine how such high participation rate of others influences an individual’s charitable behavior. We propose a moderator, namely prominence of group identity that determines the impact of high participation rates of others on an individual’s charitable behavior. Our research makes several contributions to the literature on participation of participation in the context of charitable behavior. First, we identify new moderator of the effect of other’s participation on charitable behavior, namely prominence of group identity. That is, when the prominence of group identity was not activated, the high participation rate of others had negative effect on individual charitable behavior. In contrast, when the prominence of group identity was activated, the high participation rate of others had positive effect on individual charitable behavior. Past research on a range of pro-social behaviors has found that other’s participation has a positive effect on target individuals in terms of encouraging the behavior in question. We qualify this general effect by identifying the condition where other’s participation has either a positive or a negative effect on charitable behavior. To our knowledge, our moderator of the prominence of group identity is the important identified boundary condition for the effectiveness of other’s participation. Second, we extend past research on other’s participation by developing a broader conceptual framework that includes the reduced responsibility. In summary, our results suggest that high participation rate of others increases an individual’s charitable behavior only when the salience of group identity is high.

Authors: Pietrzak L. , Piorkowska E. , Galeski A. , Bojda J. , Sowinski P.
Published: June 2018

Composites of syndiotactic polypropylene (sPP) with 5 to 17 vol.° of halloysite and 2.5 to 7.5 vol.° of stearic acid modified nano-calcium carbonate, having an average grain size of 80 nm, were prepared and examined. The effect of fillers on thermal properties of sPP was different; halloysite increased markedly peak crystallization temperature. The composites with the highest filler contents, 7.5 vol.° of calcium carbonate and 17 vol.° of halloysite, exhibited a solid-like behavior at 170 °C, with the storage modulus exceeding the loss modulus in the entire frequency range, that is 512 to 0.1 rad s−1. The composites with halloysite exhibited decreased Izod impact strength compared to neat sPP. On the contrary, 2.7 fold improvement of the impact strength was found for the composites with nano-calcium carbonate. Moreover, nano-calcium carbonate did not worsen the drawability of the materials during uniaxial drawing. It was found that debonding at calcium carbonate/sPP interface occurred both during the impact test and tensile drawing facilitating the plastic deformation of the polymer.
Peri Masalları ve Çizgi Animasyon Filmlerindeki Zihin Durumlarının İncelenmesi
Authors: Duman Nesrin , Oral Gökhan
Published: June 2018

Mentalizasyon,
“kişinin kendisindeki ve başkalarındaki
inançlar, niyetler, duygular, motivasyonlar gibi duygusal ve düşünsel süreçleri
kavrayabilme, bunları birbiriyle ilişkilendirebilme ve buna göre davranabilme
becerisi” olarak tanımlanır (akt. Hawkes, 2011, ss.230). Mentalizasyon
kavramının önemi; son yıllarda saldırganlık-şiddet çalışmaları, duygudurum
düzenlemesi, kişilik bozuklukları (özellikle borderline kişilik bozukluğu),
müdahale ve terapi programlarının oluşturulması konularında yapılan
çalışmalarda vurgulanmaktadır. Ebeveyn çocuk ilişkilerinde kullanılan
masallar, hayal dünyasına etkisiyle mentalizasyon için mükemmel bir başlangıç
noktası kabul edilmektedir (Frohne-Hagemann, 2012). Bu noktadan
hareketle masallardaki mentalizasyon katkı düzeylerinin araştırılması için doğu
ve batı kültüründen onbeşer masal incelemeye alınmıştır.  Günümüzde teknolojik gelişmeler ile değişen
sosyo-kültürel yaşam, masal kitaplarının da yerini çizgi filmlere bırakmasına
neden olmuştur (Yücel, 2015).
Çocukların masalları animasyon filmleri izleyerek öğrenmeleri nedeniyle
çalışmaya masalların postmodern formu olarak görülen animasyon filmler de dâhil
edilmiştir. Dünya genelinde en çok izlenen ilk onbeş animasyon film seçilerek
üçüncü grubu oluşturmuştur. Masal ve animasyon film metinlerdeki zihin durumu
sözcükleri CS-MST kodlama sisteminde belirtilen kategoriler altında kodlanarak
sayısallaştırılmış, sonuçlar üç grup açısından karşılaştırılmıştır. Sonuç
olarak masalların animasyon filmlere göre daha yüksek mentalizasyon katkısı
sağladığı, mentalizasyon kapasitesinin geliştirilmesinde kullanılacak kıymetli
araçlar olduğu görülmüştür.

Published: June 2018

This article is a work of literary analysis. As such, it analyzes the reading motif in Bahiyyih Nakhjavani’s The Woman Who Read Too Much through a postsecular prism. Nakhjavani’s historical novel, as the title suggests, is densely woven with metaphors that underscore a link between the secular and the sacred through the act of reading. Through the metaphors employed in the novel, the act of reading is shown to be both a material and a metaphysical act. This study owes a significant debt to John McClure’s Partial Faiths: Postsecular Fiction in the Age of Pynchon and Morrison.
The Past as a Foreign Country
Authors: Fibiger Linda
Published: June 2018

Steven Pinker’s thesis on the decline of violence since prehistory has resulted in
many popular and scholarly debates on the topic that have ranged—at times even raged—
across the disciplinary spectrum of evolution, psychology, philosophy, biology, history, and
beyond. Those disciplines that made the most substantial contribution to the empirical
data underpinning Pinker’s notion of a more violent prehistoric past, namely, archaeology
and bioarchaeology/physical anthropology, have not featured as prominently in these discussions
as may be expected. This article will focus on some of the issues resulting from
Pinker’s oversimplifi ed cross-disciplinary use of bioarchaeological data sets in support of
his linear model of the past, a model that, incidentally, has yet to be incorporated into current
accounts of violent practices in prehistory.
The Inner Demons of The Better Angels of Our Nature
Authors: Smail Daniel Lord
Published: June 2018

The Better Angels of Our Nature makes a bold contribution to the deep history of
human violence. By laying out a framework for understanding this history, Steven Pinker
has provided an important point of departure for all future scholarship in this area. Pinker’s
depiction of violence in medieval Europe, however, includes serious misrepresentations
of the historical reality of this period; his handling of the scholarship on medieval Europe
raises doubts about his treatment of other periods. This article also offers a brief review of
recent psychological literature that suggests that subjective well-being is historically invariant.
In light of this review, I argue that Better Angels is best understood not as a work of
history but as a study in moral and historical theology, and recommend that the history of
violence should feature the cognitive experiences of victims rather than aggressors.

Published: June 2018

Literatürde, genelde rekreasyon ve turizm kavramlarının her ikisinin de, boş zamanda, gönüllük esasıyla yapılan ve mutlu olma, stresten uzaklaşma, kafa dağıtma ve eğlenme gibi bireyin olumlu kendilik haline ulaşma amacıyla yaptığı faaliyetlere işaret ettiği görülmektedir. Rekreasyon kavramı, “aktivite, ruhsal durum, yaşam biçimi ve bütünsel yaklaşım” olarak literatürde tartışılsa da, düzeyler itibariyle gözlenebilir ve karşılaştırılabilir nitelikte tanımlanmamıştır. Bu haliyle farklı rekreasyon faaliyetlerinin performansını belirlemek ve karşılaştırmak da mümkün olamamaktadır. Bu araştırmanın amacı; rekreasyonu ayrık bir bilimsel yapı olarak betimlemek ve bir performans gözlemlerini mümkün kılan bir ölçek önermektir. Çalışmada bir yapı ve değişken olarak betimlenen rekreasyon “yenilenme” olarak etiketlenmiştir. Araştırma kapsamında beş ayrı saha çalışması gerçekleştirilmiş, toplamda 3 farklı şehirde 5 ayrı saha çalışmasında 1.146 katılımcıyla görüşülmüştür. Sürecin sonunda psikometrik nitelikleri bakımından tekrarlı sınamalara tabi tutulmuş, güvenilirlik ve geçerlilik bakımından araştırmacılara önerilebilecek bir “yenilenme” yapısı ve ölçeği geliştirmiştir. Bu çalışmanın özgün katkısı; bireylerin öğrenme, farklı deneyimler yaşama, uğraşlarından hoşlanma ve yeterince fiziksel aktif olma düşüncesi ile yenilenmeyi açıklayan yeni bir yapı öneren ölçeğin geliştirilmesidir.
Blind nonnegative matrix factorization algorithms to estimate the neutron flux of fission chamber detector: Application to neutron-gamma discrimination

Published: June 2018

In this study, we deal with the neutron flux monitoring inside the TRIGA MARK II reactor as one of the nonnegative matrix factorization problems. The fact that these methods of separating blind sources does not require any assumptions on the way the signal and noise were mixed has encouraged us to apply them to online neutron flux monitoring through neutron-gamma discrimination. We synthesize fission chambers output signals using the Python-based Fission Chamber simulator (pyFC). These signals are then considered as time series mixtures that are analyzed through nonnegative algorithms known as the most popular blind source separation techniques to extract original sources signals. The obtained results show that the Regularized Lee–Sung algorithm is the most appropriate method for discriminating neutrons and gammas. Furthermore, the neutron-gamma discrimination is highlighted through the computation of the cross-correlation functions between the separated source signals and pure neutron and gamma signals. The presented method provides a better characterization of the neutron and gamma signals with very high accuracy.

Part of Speech Tagging: Shallow or Deep Learning?
Authors: Östling Robert
Published: June 2018

Deep neural networks have advanced the state of the art in numerous fields, but they generally suffer from low computational efficiency and the level of improvement compared to more efficient machine learning models is not always significant. We perform a thorough PoS tagging evaluation on the Universal Dependencies treebanks, pitting a state-of-the-art neural network approach against UDPipe and our sparse structured perceptron-based tagger, efselab. In terms of computational efficiency, efselab is three orders of magnitude faster than the neural network model, while being more accurate than either of the other systems on 47 of 65 treebanks.

The increase in the prevalence of bacterial resistance to antibiotics has become one of the main health problems worldwide, thus threatening the era of antibiotics most frequently used in the treatment of infections. The need to develop new therapeutic strategies against multidrug resistant microorganisms, such as the combination of selected antimicrobials, can be considered as a suitable alternative. The in vitro activities of two groups of conventional antimicrobial agents alone and in combination with silver nanoparticles (AgNPs) were investigated against a set of ten multidrug resistant clinical isolate and two references strains by MIC assays and checkerboard testing, as well as their cytotoxicity, which was evaluated on human fibroblasts by MTT assay at the same concentration of the antimicrobial agents alone and in combination. Interesting results were achieved when the AgNPs and their combinations were characterized by Dynamic Light Scattering (DLS), Zeta Potential, Transmission Electron Microscopy (TEM), UV–visible spectroscopy and Fourier Transforms Infrared (FTIR) spectroscopy. The in vitro activities of ampicillin, in combination with AgNPs, against the 12 microorganisms showed one Synergy, seven Partial Synergy and four Additive effects, while the results with amikacin and AgNPs showed three Synergy, eight Partial Synergy and one Additive effects. The cytotoxic effect at these concentrations presented a statistically significant decrease of their cytotoxicity (p < 0.05). These results indicate that infections caused by multidrug resistant microorganisms could be treated using a synergistic combination of antimicrobial drugs and AgNPs. Further studies are necessary to evaluate the specific mechanisms of action, which could help predict undesirable off-target interactions, suggest ways of regulating a drug’s activity, and identify novel therapeutic agents in this health problem.
Acoustic Improvement of Stator–Rotor Interaction with Nonuniform Trailing Edge Blowing
Authors: Wang Wenjie , J. Thomas Peter
Published: June 2018

The results of unsteady-flow simulations and experiments are discussed to investigate active noise-reduction effects on the stator–rotor interaction in a single-stage low-speed compressor with nonuniform trailing edge blowing. It is found that for the investigated type of stator–rotor interaction noise, nonuniform trailing edge blowing has beneficial noise-reducing effects. The overall aim is to demonstrate that nonuniform trailing edge blowing can compensate momentum loss and reduce the axial thrust on rotor blades. The results illustrate how nonuniform trailing edge blowing influences the sound pressure level of the blade-passing frequencies and results in active noise reduction effects. The study was conducted using a trailing edge blowing system, a four-hole dynamic flow-field measurement system, and phase lock technology. The results obtained show that nonuniform trailing edge blowing leads to substantial noise-reduction effects, lowering sound levels by more than 10 dB with about 5‰ of inlet mass flow.

Published: June 2018

The paper presents an economic evaluation, including a cost-benefit analysis and a sensitivity analysis, of smart photovoltaic (PV) inverters with a novel Watt-Var control scheme for enhancing PV penetration in distribution systems in Taiwan. The novel Watt-Var control scheme with three operation phases is utilized to avoid the voltage violation problem during peak solar irradiation period and increase the PV real power injection, and thus can get higher PV penetration in distribution systems. To evaluate the benefit and cost of the PV investment project, the annual revenue of PV power sales, the initial capital investment cost for a PV project with or without a smart inverter, and the operating and maintenance (O&M) cost are taken into account. The paper demonstrates the analyses of net present value (NPV) and benefit-cost ratio (BCR) for the PV project. In addition, the paper also presents a sensitivity analysis to deal with the project uncertainty with respect to some affecting parameters. The analyzing results show that, under the feed-in tariffs (FITs) policy, with proper selection of PV and smart inverter capacities, the investment can be profitable, and the smart PV inverter can greatly enhance the PV penetration in distribution systems in Taiwan. These results can provide some useful information for making policy to encourage investment in solar PV industry.
Spatial Magnetic-Field Description Method Aimed at 2 × 25 kV Auto-Transformer Power Supply System in High-Speed Railway
Authors: Deng Yunchuan , Huang Ke , Su Dongdong , Liu Zhigang
Published: June 2018

Complete and accurate spatial magnetic field description is the premise of effectively assessing the power supply capability of a high-speed railway (HSR). Its evaluation indicators are the current distributions and the integrated impedance of traction network. This paper proposes a spatial magnetic-field description method for the auto-transformer (AT) power supply system. Due to the limitations of previous approaches, all the real loop circuits of the AT system are considered for structuring a loop circuit matrix. At first, different description processes are divided, respectively, into those for the right side and the left side of the load. Then, considering that two types of return conductors exist in an AT system, a certain current ratio deduced in existing studies is introduced. As the introduced current ratio of the left side of the load is approximate, an iterative scheme is adopted. By constantly adjusting current ratio to satisfy a constraint condition of circuit voltages, accurate traction network impedance is obtained. Last, in order to verify the effectiveness of the proposed description method, two real-life experiments in a Chinese HSR line are performed, which indicate that the proposed method can not only directly reflect complete and accurate current distribution, but also deduce the exact traction network integrated impedance.
Automatic Bowel Motility Evaluation Technique for Noncontact Sound Recordings

Published: June 2018

Information on bowel motility can be obtained via magnetic resonance imaging (MRI)s and X-ray imaging. However, these approaches require expensive medical instruments and are unsuitable for frequent monitoring. Bowel sounds (BS) can be conveniently obtained using electronic stethoscopes and have recently been employed for the evaluation of bowel motility. More recently, our group proposed a novel method to evaluate bowel motility on the basis of BS acquired using a noncontact microphone. However, the method required manually detecting BS in the sound recordings, and manual segmentation is inconvenient and time consuming. To address this issue, herein, we propose a new method to automatically evaluate bowel motility for noncontact sound recordings. Using simulations for the sound recordings obtained from 20 human participants, we showed that the proposed method achieves an accuracy of approximately 90% in automatic bowel sound detection when acoustic feature power-normalized cepstral coefficients are used as inputs to artificial neural networks. Furthermore, we showed that bowel motility can be evaluated based on the three acoustic features in the time domain extracted by our method: BS per minute, signal-to-noise ratio, and sound-to-sound interval. The proposed method has the potential to contribute towards the development of noncontact evaluation methods for bowel motility.
Dynamic Cultivation of Mesenchymal Stem Cell Aggregates
Authors: Egger Dominik , Tripisciano Carla , Weber Viktoria , Dominici Massimo , Kasper Cornelia
Published: June 2018

Mesenchymal stem cells (MSCs) are considered as primary candidates for cell-based therapies due to their multiple effects in regenerative medicine. Pre-conditioning of MSCs under physiological conditions—such as hypoxia, three-dimensional environments, and dynamic cultivation—prior to transplantation proved to optimize their therapeutic efficiency. When cultivated as three-dimensional aggregates or spheroids, MSCs display increased angiogenic, anti-inflammatory, and immunomodulatory effects as well as improved stemness and survival rates after transplantation, and cultivation under dynamic conditions can increase their viability, proliferation, and paracrine effects, alike. Only few studies reported to date, however, have utilized dynamic conditions for three-dimensional aggregate cultivation of MSCs. Still, the integration of dynamic bioreactor systems, such as spinner flasks or stirred tank reactors might pave the way for a robust, scalable bulk expansion of MSC aggregates or MSC-derived extracellular vesicles. This review summarizes recent insights into the therapeutic potential of MSC aggregate cultivation and focuses on dynamic generation and cultivation techniques of MSC aggregates.
Neurophysiological Markers of Statistical Learning in Music and Language: Hierarchy, Entropy and Uncertainty
Authors: Daikoku Tatsuya
Published: June 2018

Statistical learning (SL) is a method of learning based on the transitional probabilities embedded in sequential phenomena such as music and language. It has been considered an implicit and domain-general mechanism that is innate in the human brain and that functions independently of intention to learn and awareness of what has been learned. SL is an interdisciplinary notion that incorporates information technology, artificial intelligence, musicology, and linguistics, as well as psychology and neuroscience. A body of recent study has suggested that SL can be reflected in neurophysiological responses based on the framework of information theory. This paper reviews a range of work on SL in adults and children that suggests overlapping and independent neural correlations in music and language, and that indicates disability of SL. Furthermore, this article discusses the relationships between the order of transitional probabilities (TPs) (i.e., hierarchy of local statistics) and entropy (i.e., global statistics) regarding SL strategies in human’s brains; claims importance of information-theoretical approaches to understand domain-general, higher-order, and global SL covering both real-world music and language; and proposes promising approaches for the application of therapy and pedagogy from various perspectives of psychology, neuroscience, computational studies, musicology, and linguistics.
Single Wall Carbon Nanotubes Synthesis through Methane Chemical Vapor Deposition over MCM-41–Co Catalysts: Variables Optimization
Authors: Ramírez Rodríguez Frank , López Betty , Giraldo Luis
Published: June 2018

MCM-41–Co catalysts were tested in the synthesis of single wall carbon nanotubes (SWCNTs) through methane chemical vapor deposition (CVD), varying total cobalt content, synthesis temperature, methane flow rate, and deposition time. All variables showed a relationship with total carbon deposition, graphitic quality according to Raman results. Cobalt content showed a maximum activity at 4%, but the structural quality is best at 3%. Flow rate does not affect the quality up to 300 cm3 min−1, but deposition time leads to the formation of highly disordered carbon species passing methane for periods longer than 30 min, concluding that optimal variables are a methane deposition temperature of 800 °C, a 300 cm3 min−1 methane flow rate, and a 30 min of methane injection time, leading to a 5.4% carbon mass content and 5.1 G/D area ratios.
