Is Labor Market Mismatch a Big Deal in Japan?
Authors: Shibata Ippei 
Published: May 2020

Abstract
This paper estimates Japanese labor market mismatch between 2000 and 2019 by using the method of Sahin et al. (“Mismatch Unemployment.” The American Economic Review 104 (11): 3529–64, 2014). We quantify contract-type (regular or non-regular), employment-type (full or part-time), and occupational mismatch and their respective contributions to changes in unemployment. All three types of mismatch show a countercyclical pattern, sharply increasing during the global financial crisis (GFC), but slowly declining during the recovery. Contract-type and occupational mismatch accounted for a significant portion of the rise in the unemployment rate during the GFC, each accounting for around 30 and 20–40 percent, respectively. Employment-type mismatch, on the other hand, accounted for much less–at around 15 perecent of the rise in unemployment for the same period.
Titanium coating: introducing an antibacterial and bioactive chitosan-alginate film on titanium by spin coating
Authors: Vakili Nasim , Asefnejad Azadeh 
Published: May 2020

AbstractCoating of titanium (Ti) implants with biocompatible polymers were performed to improve bone healing. In this study, pure Ti implants were coated via chitosan and alginate by spin coating method at 1000, 4000, and 8000 rpm. The coating layer was cross-linked by calcium chloride. Their chemical structures were analyzed by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) evaluations. The morphology of the created coating was observed by scanning electron microscopy (SEM), and the best uniformity was observed in the prepared coating at 8000 rpm (6093× g) spinal speed. The adhesion strength of the coating layer on the substrate was evaluated by the adhesion pull-off test. Also, the best adhesion strength was achieved at an 8000 rpm (6093× g) coating rate. Bioactivity of the chitosan-alginate coating on Ti sheets was evaluated by soaking the samples in a simulated body fluid (SBF) solution. The apatite formation on prepared Ti sheets was investigated by SEM, XRD, and energy dispersive X-ray spectroscopy (EDS). A higher mineralization appeared on coated samples compared with pure Ti. The antibacterial behavior of the implants was analyzed by bacterial counting against Escherichia coli. The presence of chitosan and alginate on the Ti sheets resulted in a better antibacterial effect. In-vitro experiments, with L929 fibroblast cells, confirmed the biocompatibility of the implants. Coating the Ti implants with chitosan and alginate improved biomineralization and biological behavior of the implant especially at the spinal speed of 8000 rpm (6093× g). These implants can support osteoblast cell adhesion and facilitate bone regeneration.

AbstractElectrocardiography (ECG) signals and the information obtained through the analysis of these signals constitute the main source of diagnosis for many cardiovascular system diseases. Therefore, accurate analyses of ECG signals are very important for correct diagnosis. In this study, an ECG analysis toolbox together with a user-friendly graphical user interface, which contains the all ECG analysis steps between the recording unit and the statistical investigation, is developed. Furthermore, a new feature calculation methodology is proposed for ECG analysis, which carries distinct information than amplitudes and durations of ECG main waves and can be used in artificial intelligence studies. Developed toolbox is tested using both Massachusetts Institute of Technology-Beth Israel Hospital (MIT-BIH) Arrhythmia ECG Database and an experimentally collected dataset for performance evaluation. The results show that ECG analysis toolbox presented in this study increases the accuracy and reliability of the ECG main wave detection analysis, highly fasten the process duration compared to manual ones and the new feature set can be used as a new parameter for decision support systems about ECG based on artificial intelligence.
New evidence regarding the early history of the Monastery of Vatopedi (Mt Athos): unpublished sigillographical material
Authors: Stavrakos Christos , Liakos Dimitrios 
Published: May 2020

Abstract
This paper deals with an unpublished lead seal was found during the excavation works within the chandler’s workshop of Vatopedi, a later structure which was added to the eastern face of the bell tower (1427). The seal names a Constantine, chartoularios and epi tou patriarchikou sekretou and dates back to 10th till early 11th century. It is one of the rare direct sources regarding the very early period of the monastery, from which we have no other information, and serves to highlight the attention which the central ecclesiastical administration placed upon it already from the first years after its founding. It also shows the vibrant activities of its monks and their notable network of contacts with high-ranking political and ecclesiastical officials in the capital.

Multimodal Discourse Analysis of Judges’ Footing Shifts in Criminal Courtroom
Authors: Chen Jinshi 
Published: May 2020

AbstractThe paper, based on the concept of FOOTING, makes a multimodal discourse analysis of the relationship between the judge’s discourse and his footing shifts in a criminal courtroom. The results show that in the interaction, multimodal resources in judges’ discourse include conversational features (prolonging keywords, interrupting, repeating, taking turns, etc.), acoustic ones (ascending F0 for pitches and dB for intensity, transition tracks between consonants and formants of vowels, duration of some keywords in important sentences, etc.), and visual ones (facing other parties, facing the materials, etc.). The multimodal resources activate different judges’ footings, including ANIMATOR, ANIMATOR + AUTHOR and ANIMATOR + AUTHOR + PRINCIPAL, and identify the judge’s footing shifts in the courtroom. The results also demonstrate that the judge’s footing shifts perform the functions of trial organizing, information confirming, fact investigating, spokesperson of the collegial panel, law educating and so on in criminal trials.
Mock Impoliteness and Co-Construction of Hudui Rituals in Chinese Online Interaction
Authors: Zhao Linsen 
Published: May 2020

AbstractThis paper examines an under-researched phenomenon of mock impoliteness in Chinese online interaction, namely, the practice of hudui (lit. reciprocal jocular abuse) as a solidarity enhancing device among acquaintances. Drawing on data from Qzone interaction among Chinese university students, this study focuses on ritual features, sequential patterns and interpersonal functions of hudui through the lens of Kádár’s (2013, 2017) interpersonal ritual theory. The results show that hudui is co-constructed by the online participants with the symmetric pattern of mutual abuse, which distinguishes it from previous studies of jocular abuse (i.e., the asymmetric pattern of abuser– recipient). They also reveal that hudui accomplishes various kinds of relational work, including fostering intimacy, enhancing mutual affection-based face and creating amusement.
A New Mixed Functional-probabilistic Approach for Finite Element Accuracy
Authors: Chaskalovic Joël , Assous Franck 
Published: May 2020

Abstract
The aim of this paper is to provide a new perspective on finite element accuracy. Starting from a geometrical reading of the Bramble–Hilbert lemma, we recall the two probabilistic laws we got in previous works that estimate the relative accuracy, considered as a random variable, between two finite elements

P
k

{P_{k}}

and

P
m

{P_{m}}

(

k
<
m

{k<m}

). Then we analyze the asymptotic relation between these two probabilistic laws when the difference

{m-k}

goes to infinity. New insights which qualify the relative accuracy in the case of high order finite elements are also obtained.
On derived equivalences and homological dimensions
Authors: Fang Ming , Hu Wei , Koenig Steffen 
Published: May 2020

Abstract
Unlike Hochschild (co)homology and K-theory, global and dominant dimensions of algebras are far from being invariant under derived equivalences in general. We show that, however, global dimension and dominant dimension are derived invariant when restricting to a class of algebras with anti-automorphisms preserving simples. Such anti-automorphisms exist for all cellular algebras and in particular for many finite-dimensional algebras arising in algebraic Lie theory. Both dimensions then can be characterised intrinsically inside certain derived categories. On the way, a restriction theorem is proved, and used, which says that derived equivalences between algebras with positive ν-dominant dimension always restrict to derived equivalences between their associated self-injective algebras, which under this assumption do exist.
Verdinglichung und das Netz der Normen
Authors: Thompson Michael J. 
Published: May 2020

Abstract
This paper proposes a reconstruction of Georg Lukács’ thesis of reification by viewing it through the normative theory of consciousness. As I see it, reification of consciousness is the result of the ways that norms that have been patterned by external social systems come to be absorbed into the background structures of cognition. As a result, consciousness becomes increasingly fitted to these normative patterns. A web of norms therefore comes to heteronomously link consciousness and social systems via processes of socialisation. I end with a consideration of how a theory of critical judgment can be used to overcome this reification of consciousness, all the while sticking to Lukács’ basic line of argument.

Ulam type stability for non-instantaneous impulsive Caputo fractional differential equations with finite state dependent delay
Authors: Agarwal Ravi , Hristova Snezhana , O’Regan Donal 
Published: May 2020

Abstract
Four Ulam type stability concepts for non-instantaneous impulsive fractional
differential equations with state dependent delay are introduced. Two different approaches to the interpretation of solutions are investigated. We study the case of an unchangeable lower bound of the Caputo fractional derivative and the case of a lower bound coinciding with the point of jump for the solution. In both cases we obtain sufficient conditions for Ulam type stability. An example is also provided to illustrate both approaches.

Published: May 2020

Abstract
Simultaneously identify superior performing in terms of seed yield and seed oil content and broad adaptation across a wide range of different environments is an important target for sunflower breeder. So, 10 sunflower genotypes were evaluated across the eight various environments created by sowing at four locations i. e. Kafr El Hamam/ Sharkia, Shandaweel /Sohag, Tag El Ezz/ Dakahlia and Al Arish/ North Sinai Agricultural Research Stations, Agricultural Research Center (ARC), Egypt during the two successive summer seasons 2018 and 2019 using randomized complete block designs with four replications in each environment. Results showed that mean squares due to environments, genotypes and their interaction were highly significant for seed yield and seed oil content. Most stability approaches revealed that high performing stable genotypes were L240 for seed yield and Sakha 53, L110 and L235 for seed oil content under divergent environments. Hence, these four stable sunflower genotypes could be behaved as good breeding materials stock for sunflower improvement.

Abstract
Ants (Hymenoptera, Apocrita, Aculeata, Formicoidea) comprise a well-succeeded group of animals. Like bees and wasps, ants are mostly venomous, having a sting system to deliver a mixture of bioactive organic compounds and peptides. The predatory giant ant Dinoponera quadriceps belongs to the subfamily Ponerinae that includes one of the largest known ant species in the world. In the present study, low molecular weight compounds and peptides were identified by online peptide mass fingerprint. These include neuroactive biogenic amines (histamine, tyramine, and dopamine), monoamine alkaloid (phenethylamine), free amino acids (e.g. glutamic acid and proline), free thymidine, and cytosine. To the best of our knowledge, most of these components are described for the first time in an ant venom. Multifunctional dinoponeratoxin peptide variants (pilosulin- and ponericin-like peptides) were characterized that possess antimicrobial, hemolytic, and histamine-releasing properties. These venom components, particularly peptides, might synergistically contribute to the overall venom activity and toxicity, for immobilizing live prey, and for defending D. quadriceps against aggressors, predators, and potential microbial infection.
PINK1 and Parkin: team players in stress-induced mitophagy
Authors: Bader Verian , Winklhofer Konstanze F. 
Published: May 2020

Abstract
Mitochondria are highly vulnerable organelles based on their complex biogenesis, entailing dependence on nuclear gene expression and efficient import strategies. They are implicated in a wide spectrum of vital cellular functions, including oxidative phosphorylation, iron-sulfur cluster synthesis, regulation of calcium homeostasis, and apoptosis. Moreover, damaged mitochondria can release mitochondrial components, such as mtDNA or cardiolipin, which are sensed as danger-associated molecular patterns and trigger innate immune signaling. Thus, dysfunctional mitochondria pose a thread not only to the cellular but also to the organismal integrity. The elimination of dysfunctional and damaged mitochondria by selective autophagy, called mitophagy, is a major mechanism of mitochondrial quality control. Certain types of stress-induced mitophagy are regulated by the mitochondrial kinase PINK1 and the E3 ubiquitin ligase Parkin, which are both linked to autosomal recessive Parkinson’s disease.
Microstructural evolution during high-temperature tensile creep at 1,500°C of a MoSiBTiC alloy
Authors: Uemura Sojiro , Kamata Shiho Yamamoto , Yoshimi Kyosuke , Tsurekawa Sadahiro 
Published: May 2020

AbstractMicrostructural evolution in the TiC-reinforced Mo–Si–B-based alloy
during tensile creep deformation at 1,500°C and 137 MPa was
investigated via scanning electron microscope-backscattered electron diffraction
(SEM-EBSD) observations. The creep curve of this alloy displayed no clear steady
state but was dominated by the tertiary creep regime. The grain size of the
Moss phase increased in the primary creep regime. However, the grain
size of the Moss phase was found to remarkably decrease to
<10 µm with increasing creep strain in the tertiary creep
regime. The EBSD observations revealed that the refinement of the Moss
phase occurred by continuous dynamic recrystallization including the transformation
of low-angle grain boundaries to high-angle grain boundaries. Accordingly, the
deformation of this alloy is most likely to be governed by the grain boundary sliding
and the rearrangement of Moss grains such as superplasticity in the
tertiary creep regime. In addition, the refinement of the Moss grains
surrounding large plate-like T2 grains caused the rotation of their
surfaces parallel to the loading axis and consequently the cavitation preferentially
occurred at the interphases between the end of the rotated T2 grains and
the Moss grains.
China–India relations in Eurasia: Historical legacy and the changing global context
Authors: Denisov Igor , Safranchuk Ivan , Bochkov Danil 
Published: May 2020

Abstract
The relationship between the People’s Republic of China and the Republic of India has traditionally been seen in terms of the interaction of two different trends—cooperation and competition. At the same time, the positive or negative dynamics of China–Indian contacts have mostly been shaped by the extent to which the political leadership of China and India have been prepared at various times to be guided by pragmatic interests and the desire to overcome the legacy of the past. This set of problems includes long-standing territorial disputes, New Delhi’s suspicions of the “all-weather strategic partnership” between Beijing and Islamabad, as well as the sensitive issues of Tibet and the Dalai Lama. Although the idea of ChIndia, as a condominium of the global interests of the two Asian giants and a manifestation of their growing interdependence, is no longer relevant, this article argues that cooperation or confrontation between China and India should not be linked solely to historical matters, but should be viewed from a broader regional and international perspective.
Artificial, cheap, fake: Free associations as a research method for outdoor billboard advertising and visual pollution
Authors: Urban Marek , Avilés Dany Josué Vigil , Bojović Miloš , Urban Kamila 
Published: May 2020

Abstract
The free association method is often employed in marketing research to investigate perceptions of a particular product or brand in different socio-cultural groups of customers. In our research, international and domestic students produced free associations in response to photographs of outdoor billboards from two different locations in one city (city centre and outskirts). The results indicate that free associations can depict qualitative aspects of outdoor billboards like poor quality (relating to the categories of amateurish and fake), problematic content (relating to female stereotypes, gender stereotypes and cultural differences), and that they have the potential to capture the general atmosphere of the neighbourhood (categories of decay, depression, danger and past).
Inadequate awareness of cervical cancer and its prevention among young women of Delhi, India: public health policy implications
Authors: Sharma Priyanka , Bhilwar Meenakshi , Tiwari Poornima , Parija Pragyan Paramita , Saha Sunil Kumar , Mehra Kriti 
Published: May 2020

Abstract

Background
The increasing burden of cancer is a cause of concern worldwide including in India. Cervical cancer is amongst the most common cancers among women associated with high morbidity and mortality. Younger women are at risk of acquiring human papilloma virus (HPV) infection that can lead to cervical cancer later in life. The present study is an attempt to assess awareness about cervical cancer, its prevention and HPV among young women so that future policies can be designed accordingly.

Methodology
This was a cross-sectional study conducted among college-going women students of Delhi. Data was collected using a pre-designed, pretested semi-structured tool followed by descriptive statistical analysis.

Results
Although 83% women students had heard of cervical cancer, the signs and symptoms were known to less than half (41.9%) of the students. HPV vaccine availability was known to 56.0% of the students, but very few students were vaccinated (15.0%). Similar disparity was also found in screening knowledge and practices.

Conclusion
With poor knowledge about risk factors, and preventive strategies among young women, this study highlights the need for health education programmes related to cervical cancer targeting young women. As most of the risk factors of cervical cancer are modifiable, awareness generation at a young age could bring about a paradigm shift in incidence and the mortality associated with it.
Behavioural and neuro-electrical correlates of cognitive performance in young mobile gamers of endless runner and match three genres
Authors: Jiwal Sekhar , Jain Preeti , Jain Ajay Kumar 
Published: May 2020

Abstract
Video game players have been shown to significantly out-perform non-video game players on a wide range of cognitive tasks. Exposure to specific genres of video games may also have a significant bearing in impacting certain task-specific domains of cognition. However, there is limited availability of scientific literature exploring the role of mobile game sub-genres on the cognitive abilities of an individual. The present study was therefore conducted to assess and compare the impact of playing either endless running video games (ERGs) or match three video games (MTGs) on behavioral and neuro-electrical correlates of cognitive performance in young adults, by using reaction time (RT) and P300, respectively. The ERG group included 45 male:female (M:F) ratio = 38:7 and the MTG group included 39 (M:F = 21:18) subjects who played ≥5 h/week of each respective video game genre in past 6 months. The ERG group had better behavioral performance in comparison to the MTG group, as indexed by their significantly faster visual reaction time (VRT). The ERG subjects also had significantly lower P300 amplitudes as compared to MTG subjects. However, no difference in either auditory reaction time (ART) or P300 latency could be ascertained between the two groups. These results suggest that not only were ERG players able to make faster decisions and performed better in visuo-motor tasks but, also had better optimization of neural resources in them as compared to the MTG players. The current data supports the notion that not only exposure to video games but also the nature (i.e. genre) of mobile game play determines the extent to which neural processes concerned with attentional orientation, information processing and cognitive control are influenced.
A Parametric Bootstrap for the Mean Measure of Divergence
Authors: Zertuche F. , Meza-Peñaloza A. 
Published: May 2020

Abstract
For more than 50 years the Mean Measure of Divergence (MMD) has been one of the most prominent tools used in anthropology for the study of non-metric traits. However, one of the problems, in anthropology including palaeoanthropology (more often there), is the lack of big enough samples or the existence of samples without sufficiently measured traits. Since 1969, with the advent of bootstrapping techniques, this issue has been tackled successfully in many different ways. Here, we present a parametric bootstrap technique based on the fact that the transformed θ, obtained from the Anscombe transformation to stabilize the variance, nearly follows a normal distribution with standard deviation

$\sigma = 1 / \sqrt{N + 1/2}$

σ
=
1

/

N

, where N is the size of the measured trait. When the probabilistic distribution is known, parametric procedures offer more powerful results than non-parametric ones. We profit from knowing the probabilistic distribution of θ to develop a parametric bootstrapping method. We explain it carefully with mathematical support. We give examples, both with artificial data and with real ones. Our results show that this parametric bootstrap procedure is a powerful tool to study samples with scarcity of data.
