Treewidth of the Generalized Kneser Graphs
Authors: Liu Ke , Cao Mengyu , Lu Mei
Published: April 2022

Let $n$, $k$ and $t$ be integers with $1\leq t< k \leq n$. The generalized Kneser graph $K(n,k,t)$ is a graph whose vertices are the $k$-subsets of a fixed $n$-set, where two $k$-subsets $A$ and $B$ are adjacent if $|A\cap B|<t$. The graph $K(n,k,1)$ is the well-known Kneser graph. In 2014, Harvey and Wood determined the exact treewidth of the Kneser graphs for large $n$ with respect to $k$. In this paper, we give the exact treewidth of the generalized Kneser graphs for $t\geq2$ and large $n$ with respect to $k$ and $t$. In the special case when $t=k-1$, the graph $K(n,k,k-1)$ usually denoted by $\overline{J(n,k)}$ which is the complement of the Johnson graph $J(n,k)$. We give a more precise result for the exact value of the treewidth of $\overline{J(n,k)}$ for any $n$ and $k$.
Weighted Words at Degree Two, II: Flat Partitions, Regular Partitions, and Application to Level One Perfect Crystals
Authors: Konan Isaac
Published: April 2022

In a recent work, Keith and Xiong gave a refinement of Glaisher's theorem by using a Sylvester-style bijection. In this paper, we introduce two families of colored partitions, flat and regular partitions, and generalize the bijection of Keith and Xiong to these partitions. We then state two results, the first at degree one, where partitions have parts with primary colors, and the second result at degree two for secondary-colored partitions, using the result of the first paper of this series on Siladić's identity. These results allow us to easily retrieve the Frenkel-Kac character formulas of level one standard modules for the type $A _{2n}^{(2)}, D_{n+1}^{(2)}$ and B_n^{(1)}$ , and also to make the connection between the result stated in paper one and the representation theory.
Ramsey Numbers of Fans and Large Books
Authors: Liu Meng , Li Yusheng
Published: April 2022

For graphs $G$ and $H$, the Ramsey number $R(G,H)$ is the minimum integer $N$ such that any red/blue edge coloring of $K_N$ contains either a red $G$ or a blue $H$. Let $G+H$ be the graph obtained from vertex disjoint $G$ and $H$ by adding new edges connecting $G$ and $H$ completely, $F_m=K_1+mK_2$ and $B_p(n)=K_p+nK_1$. It is shown $R(F_m,B_p(n))=2(n+p-1)+1$ for fixed $m, p$ and large $n$.
Reframing Roman Liturgy
Authors: Malesevic Filip
Published: April 2022

This book presents a critical edition of a collection of liturgical manuscripts that the
Augustinian friar Onofrio Panvinio (1530–1568) assembled in the 1560s for the Cardinal
Alessandro Farnese as well as for Hans Jakob Fugger in Augsburg. Onofrio Panvinio is
primarily known for his antiquarian studies about ancient Rome and for his edition
of Bartolomeo Platina’s Lives of the Popes. His preoccupation with the Roman rite,
however, remains until today largely unnoticed by modern scholarship. This edition
of Panvinio’s Vetusti aliquot rituales libri highlights his interests in the development
of Roman liturgy during the last sessions of the Council of Trent (1545–1563) by presenting
the various documentary as well as cultural layers of Panvinio’s collection of
Roman ritual manuscripts.

Tensile Properties and Manufacturing Defectives of Short Carbon Fiber Specimens Made with the FDM Process
Authors: Blaj Madalina-Ioana , Zaharia Sebastian-Marian , Pop Mihai Alin , Oancea Gheorghe
Published: April 2022

With the fourth industrial revolution, Additive Manufacturing started to offer new possibilities of manufacturing, Fused Deposition Modeling being one of the most used processes for fabrication. In this paper, the studied specimens are manufactured based on the Fused Deposition Modeling (FDM) method, with a filament of short carbon fiber and polyethylene terephthalate (PET) matrix, with a variation of the layer thickness. For the resulted specimens the tensile properties are determined according to ASTM D638. The most advantageous results are obtained for the layer thickness of 0.15 mm, with the tensile strength of 58 MPa. Based on the stress-strain curves which are presented in this paper, it also can be assumed that the material is brittle. The results of the mechanical properties are very similar for each group of specimens and it can be assumed that the mechanical properties are homogenous due to the material quality and the machine performances. For all the specimens the rupture location is almost in the same area. Due to the difficulty of carbon fiber filament printing, the manufacturing defectives which appear during the manufacturing process are detected, the most common manufacturing defectives being the material gaps from each specimen, which are identified with microstructural analysis. As failure modes, the most common failure criteria are the delamination and the matrix cracks.

Published: April 2022

In the recent past, the demand for multifunctional and lightweight materials have increased steadily creating an increase in demand for Hybrid polymer matrix composite which consists multiple fibers in conventional resins. In this study, a hybrid composite comprising of two reinforcements - natural silk fiber and E-Glass fiber - in an Epoxy resin matrix which is a partially eco-friendly composite has been fabricated and the effect of drilling, by using an 8 facet solid carbide drill, on the surface roughness has been studied. Taguchi�s L27 Orthogonal array was used for experimentation by modifying three parameters - feed rate, spindle speed and drill diameter - on three levels (low, medium and high) and thereby studying the effects. From the results of experimentation it has been observed that increase in spindle speed and drill diameter reduces surface roughness however it increases with increase in feed rate. Further, regression analysis and Fuzzy modeling are used in order to determine optimum parameter values to get the desired surface finish. Good agreement between the experimental, regression and fuzzy model is observed with the correlation coefficient of 0.9814 and 0.9677 respectively.

Published: April 2022

At the beginning of the 90 s on the market of dental restoration materials appeared compomers, polyacid modified composite resins (PMC). The term compomer suggests a combination of glass-ionomer and composite technology. This has led to confusion about how it relates to dental structures. The properties and adhesion of compomers to dental structures suggest a closer connection with composites than with glass ionomers. They do not have direct chemical adhesion to any tooth structure it adheres similar to the composites through a separate binding agent. However, their proximity to composites does not make them substitutes of composites. Compomers are a versatile class of dental restorative biomaterials, whose clinical benefits are particularly useful in pediatric dentistry.

Published: April 2022

Compomers have emerged by modifying dental composites in an effort to combine their desired properties, namely their good aesthetics, with those of glass ionomer cements, namely their ability to release fluoride for a long time. While this combination of good aesthetics and fluoride release may seem to give compomers an advantage, their poor mechanical properties limit their use. The main components of the compomers are polymerizable dimethacrylate resins, such as urethane dimetha-crylate and TCB (a butantetracarboxylic acid reaction product) and hydroxyethyl methacrylate and ionizable glass fillers, such as fluorosilicate glass.

Published: April 2022

This in vitro study aimed to compare the fracture resistance between pressed custom-made polyetheretherketone (PEEK) post and core and fibre reinforced post and composite core. A total of 40 single rooted extracted teeth were selected, endodontically treated, and prepared to receive the posts. Specimens were randomly divided into two main groups (n=20/group): group 1, (PEEK); group 2, fibre post. PEEK post was manufactured with a computer-aided design/computer-aided manufacturing system further divided into four sub groups (P7, P12, F7, F12) based on lengths 7 and 12 mm at which the posts were cemented. All posts were cemented with self-adhesive resin cement, and specimens were stored in 0.1% thymol solution during the experiment at all the times except during preparation and testing. A universal testing machine was used to measure the fracture resistance. The fracture resistance values (mean and SD, in newtons) were 1255N (P7), 1562N (P12), 1065N (F7), and 1384N (F12). Only P12 exhibited a significant difference (p,0.05). The turkey test showed an association between failure mode and post and- core material. In the remaining groups, most failures were nonrepairable and related to fracture. Customized post-and-cores of PEEK exhibited good mechanical performance. Their fracture resistance was comparable to that observed for fibre posts.
Online measurement of learning temporal statistical structure in categorization tasks

Published: April 2022

The ability to grasp relevant patterns from a continuous stream of environmental information is called statistical learning. Although the representations that emerge during visual statistical learning (VSL) are well characterized, little is known about how they are formed. We developed a sensitive behavioral design to characterize the VSL trajectory during ongoing task performance. In sequential categorization tasks, we assessed two previously identified VSL markers: priming of the second predictable image in a pair manifested by a reduced reaction time (RT) and greater accuracy, and the anticipatory effect on the first image revealed by a longer RT. First, in Experiment 1A, we used an adapted paradigm and replicated these VSL markers; however, they appeared to be confounded by motor learning. Next, in Experiment 1B, we confirmed the confounding influence of motor learning. To assess VSL without motor learning, in Experiment 2 we (1) simplified the categorization task, (2) raised the number of subjects and image repetitions, and (3) increased the number of single unpaired images. Using linear mixed-effect modeling and estimated marginal means of linear trends, we found that the RT curves differed significantly between predictable paired and control single images. Further, the VSL curve fitted a logarithmic model, suggesting a rapid learning process. These results suggest that our paradigm in Experiment 2 seems to be a viable online tool to monitor the behavioral correlates of unsupervised implicit VSL.
An attentional limbo: Saccades become momentarily non-selective in between saliency-driven and relevance-driven selection

Published: April 2022

Human vision involves selectively directing the eyes to potential objects of interest. According to most prominent theories, selection is the quantal outcome of an ongoing competition between saliency-driven signals on the one hand, and relevance-driven signals on the other, with both types of signals continuously and concurrently projecting onto a common priority map. Here, we challenge this view. We asked participants to make a speeded eye movement towards a target orientation, which was presented together with a non-target of opposing tilt. In addition to the difference in relevance, the target and non-target also differed in saliency, with the target being either more or less salient than the non-target. We demonstrate that saliency- and relevance-driven eye movements have highly idiosyncratic temporal profiles, with saliency-driven eye movements occurring rapidly after display onset while relevance-driven eye movements occur only later. Remarkably, these types of eye movements can be fully separated in time: We find that around 250 ms after display onset, eye movements are no longer driven by saliency differences between potential targets, but also not yet driven by relevance information, resulting in a period of non-selectivity, which we refer to as the attentional limbo. Binomial modeling further confirmed that visual selection is not necessarily the outcome of a direct battle between saliency- and relevance-driven signals. Instead, selection reflects the dynamic changes in the underlying saliency- and relevance-driven processes themselves, and the time at which an action is initiated then determines which of the two will emerge as the driving force of behavior.

Review question / Objective: The purpose of this review is to comprehensively evaluate the effectiveness and safety on mind-body therapies of traditional Chinese medicine for neuropathic pain. Condition being studied: According to the definition by the International Association for the Study of Pain (IASP), neuropathic pain is a kind of pain caused by lesions or diseases affecting the somatosensory nervous system. It has brought considerable negative impacts on patients and society. Neuropathic pain is a prevalent disease and can be induced by a variety of clinical conditions such as spinal cord injury (prevalence rate: 53%), induced peripheral neuropathic pain (prevalence rate: 38%), diabetic peripheral neuropathic pain (prevalence rate: 10%-26%), chemotherapy postherpetic neuralgia (3.9-42.0/10,000 people per year), prosopalgia (3-5/10,000 people per year), and so on. However, current recommended medicines for neuropathic pain management could cause dependence and adverse events. Thus, alternatives would be helpful for both patients and clinicians. Mind-body therapy in traditional Chinese medicine (TCM) has a long history in clinical practice for relieving pain and their effectiveness has not been systematically reviewed.The purpose of this review is to comprehensively evaluate the effectiveness and safety on mind-body therapies of traditional Chinese medicine for neuropathic pain.

Published: April 2022

DI's Way is present as a new media in the world of print media. Print media originating from Surabaya, and for Surabaya residents. It looks like a magazine but is published every day, has a cover layout that is not like a magazine or newspaper. The cover design, in this case, especially the layout, has an aesthetic to determine the mass media, especially print, whether the media will sell or not. However, this daily is claimed to have many fans, both in its initial form, namely a website, to becoming a daily printed in color. This study uses a qualitative method with a hermeneutic approach to explore the impression of what the cover layout design shows that is not like a magazine or newspaper to Surabaya. The hermeneutic method is carried out by interpreting the data seen in the DI's way cover design, layout theory, and also matters related to Surabaya. This data mining is done by looking at the cover layout design in terms of the use of grids, margins, and also text and image elements. The results that can be seen are as a DI's way daily like a newspaper or newsletter that has a template for each edition with a cover layout showing the impression that the main interest of this media is to be able to tell important news to the City of Surabaya, by always using a large size for the main news photo and also for the text element (headline) but the arrangement can still be followed as a comfortable reading flow. A large portion seems to want to show the impression of the characteristics of the City of Surabaya as a city of heroes which has a great and passionate fighting spirit. Meanwhile, supporting news is placed below it according to the order of its news value, showing the impression of the vision that the City of Surabaya has in building a city that is more advanced from all aspects. In addition, grid management displays the impression of being a local mass media that is regularly reported in its media according to the identity of a daily media that has a news order position like an inverted pyramid.
İhanetten İmparatorluğa: IV. Romanos Diogenes
Authors: Keçiş Murat
Published: April 2022

Bizans İmparatorluğu olarak da bilinen Doğu Roma, çağın gereklerine uyum sağlamayı başaran güçlü ordusu sayesinde varlığını asırlarca devam ettirebilmiştir. İmparator IV. Romanos Diogenes döneminde (1068-1071) bütün imkânlar seferber edilerek Büyük Selçuklu Devleti’ni ortadan kaldırmaya yönelik hazırlanan özgüveni yüksek bu ordu, Malazgirt’te Sultan Alp Arslan karşısında beklenmedik ağır bir yenilgiye uğramıştır (26 Ağustos 1071). Bizans askerî tarihinde bir kırılma noktası olarak kabul edilen bu hezimet üzerine yapılan tartışmalar daha çok Büyük Selçuklu ordusunun başarısı ve kazanımları üzerine odaklanırken Bizans ordusunun yenilgisine yol açan stratejik hata/ hatalar üzerinde yeterince durulmamıştır. Bu yaklaşım çerçevesinde, yenilginin temel nedeninin Selçuklu ordusunun gücünden ziyade İmparator IV. Romanos’un savaş öncesindeki psikolojik durumunun ve geleneksel imparatorluk düşüncesinin etkisiyle Bizans ordusunun sayısal çoğunluğuna-moral üstünlüğüne fazlaca güven duymuş olduğu göz ardı edilmiştir. Bu çalışmada, söz konusu durumu aydınlığa kavuşturmak adına, öncelikle Bizans ordusunun gelişim seyri ile IV. Romanos Diogenes’in imparator olma sürecine değinilmiş ve ardından belirtilen faktörlerin Malazgirt Savaşı’nın kaybedilmesindeki belirleyici rolü üzerinde durulmuştur.

Değişim Çağında Osmanlı İstanbulu’nda Oyuncaklar ve Oyun Nesneleri
Authors: Erdinçli İhsan
Published: April 2022

Çalışmanın amacı, Osmanlı İstanbulu’nda çocukların hangi oyuncaklar ve oyun nesneleriyle oynadığını, oyuncakçılığın durumunu da göz ardı etmeden somut olarak belirlemektir. Bu bağlamda 17. yüzyılın ikinci yarısından itibaren oyuncak imalinde öne çıkan İstanbul’un Eyüp semtine odaklanılmıştır. 19. yüzyılın ortalarındaysa endüstriyel üretim alafranga oyuncaklar, Avrupa menşeli mağazaların rafarında görünür hale gelmiştir. Nispeten daha iyi bilinse de Eyüp oyuncakçılığının ve oyuncaklarının değişim sürecindeki durumu, dönemin çocukları açısından nasıl bir değere sahip olduğu incelenmemiştir. Bunun nedenlerinden biri; dönemin yazınında geleneksel ve modern oyuncaklara yönelik nasıl bir yaklaşım sergilendiğinin sorgulanmamasıdır. Araştırmacılar; modern çağda Avrupai oyuncakların İstanbul’a girdiğinden sıklıkla bahsetmekte ama bunların somut olarak nelerden oluştuğunu nadiren belirtmektedir. Sözü edilen odak noktalarından hareketle planlanan çalışma; arşiv belgeleri, çağdaş gözlemler, yıllıklar, gazeteler ve çocuk dergileri ile mecmualarına dayanmaktadır. Çalışmada; Eyüp oyuncakçılığının Avrupa menşeli oyuncakların İstanbul’a girmeye başlamasından olumsuz etkilendiği ama kısa süre içinde yok olmadığı ileri sürülmektedir. Alafranga oyuncaklar, 20. yüzyılın ilk çeyreğinde geleneksel Eyüp oyuncaklarının yerini almıştır. Modern eğitime daha fazla önem verilmesi, Hürriyet’in ilan edildiği 1908 yılından sonra çocuklara yönelik süreli yayınların nicelik ve niteliğinin artması ve Osmanlı aydınlarının tanıtım yazıları, Avrupai oyuncakların İstanbul pazarına hâkim olmasına katkıda bulunmuştur.

PORTRAITS OF RELIGIOUS MODERATION IN THE SALAF PESANTREN EDUCATION SYSTEM IN INDONESIA
Authors: Azizah Lailiyatul
Published: April 2022

In the history of the development of Islam, many faces of Islam have been tainted by understandings that are not actually from the teachings of Islam itself. Radicalism, liberalism, and extremism have created intolerance and terrorism in the religion. The existence of Islam as a wasaṭiyah religion is an answer to the phenomena that occur in Islam as stated in the al-Qur’ān. Due to these waves of understandings, religious institutions or even the country were unable to position themselves as moderate institutions. Salaf pesantren are considered to be the only institutions that represent religious moderation in the Islamic revival century in Indonesia. The presence of the salaf pesantren is considered as a forum for negotiating Islamic identity as a wasaṭ wa i’tidāl religion and displays a polite and peaceful Islamic figure, by offering a salafiyah curriculum and kiai as the main actors in the management of the pesantren, as well as the role of pesantren graduates in social, religious and patriotic ontexts that are proven to carry a mission and moderate values ​​that can bring Indonesian Islam to become a peripheral.

In the service sector, such as tourism and hospitality, a traveler often tries to find information about their destination digitally, comparing it to alternatives available to have the best option. This demand businesses that are in the tourism and hospitality sector to advertise their destination more creatively and informatively, such as using a travel influencer. The present research was conducted to explore how the public adopts information advertised by a social media influencer that promotes travel or leisure places, better known as a travel influencer. The Information Adoption Model (IAM) was used to explore the factors that could affect people’s perception of Information Usefulness (IU), which then affects Information Adoption (IA). Several hypotheses that were built from the IAM theoretical framework were tested using Partial Least Square Structural Equation Modelling (PLS-SEM) with 150 people as respondents; four out of the seven hypotheses were accepted. From the accepted hypotheses, it was revealed that more dimensions in the Source Credibility construct influence Information Usefulness compared to the dimensions from the Argument Quality constructs.
VOLATILITY REGIMES OF SELECTED CENTRAL EUROPEAN STOCK RETURNS: A MARKOV SWITCHING GARCH APPROACH
Authors: Chocholatá Michaela
Published: April 2022

This paper investigates the weekly stock market data of the Hungarian stock index BUX, the Czech stock index PX and the Polish stock index WIG20 spanning from January 7, 2001 to April 18, 2021. The period of more than 20 years enabled to analyse the behaviour of returns and their volatility during both the calm as well as various crises/turmoil periods. Besides the traditional GARCH-type models (GARCH and GJR-GARCH) the two-regime Markov Switching GARCHtype models (MS-GARCH and MS-GJR-GARCH) were estimated in order to examine the volatility switches of the Central European transition stock markets. The t-distribution of error terms was used to capture the dynamics of analysed returns more precisely. The results proved high volatility persistence of individual markets which substantially differed across the both regimes. Furthermore, the GJR-GARCH and MS-GJR-GARCH models clearly confirmed the presence of the leverage effect. Consideration of the MS-GARCH-type models enabled to capture various volatility switches during the analysed period attributable mainly to the global financial crisis 2008–2009, to European debt crisis in 2011 and to the Covid-19 pandemic in 2020. Interesting results were received for the Czech market with the strong leverage effect indicating completely different specification of volatility regimes by the MS-GJR-GARCH model.
Statistical Properties of the Nebular Spectra of 103 Stripped-envelope Core-collapse Supernovae*

We present an analysis of the nebular spectra of 103 stripped-envelope (SE) supernovae (SNe) collected from the literature and observed with the Subaru Telescope from 2002 to 2012, focusing on [O i] λλ6300, 6363. The line profile and width of [O i] are employed to infer the ejecta geometry and the expansion velocity of the inner core; these two measurements are then compared with the SN subtypes, and further with the [O i]/[Ca ii] ratio, which is used as an indicator of the progenitor CO core mass. Based on the best-fit results of the [O i] profile, the objects are classified into different morphological groups, and we conclude that the deviation from spherical symmetry is a common feature for all types of SESNe. There is a hint (at the ∼1σ level) that the distributions of the line profile fractions are different between canonical SESNe and broad-line SNe Ic. A correlation between [O i] width and [O i]/[Ca ii] is discerned, indicating that the oxygen-rich material tends to expand faster for objects with a more massive CO core. Such a correlation can be utilized to constrain the relation between the progenitor mass and the kinetic energy of the explosion. Further, when [O i]/[Ca ii] increases, the fraction of objects with Gaussian [O i] profile increases, while those with double-peaked profile decreases. This phenomenon connects ejecta geometry and the progenitor CO core mass.

Published: April 2022

We investigate the cold and warm gas content, kinematics, and spatial distribution of six local massive elliptical galaxies to probe the origin of the multiphase gas in their atmospheres. We report new observations, including Stratospheric Observatory for Infrared Astronomy [C ii], Atacama Large Millimeter/submillimeter Array CO, Multi Unit Spectroscopic Explorer (MUSE) Hα+[N ii], and Very Large Array (VLA) radio observations. These are complemented by a large suite of multiwavelength archival data sets, including thermodynamical properties of the hot gas and radio jets, which are leveraged to investigate the role of active galactic nucleus (AGN) feeding/feedback in regulating the multiphase gas content. Our galactic sample shows a significant diversity in cool gas content, spanning filamentary and rotating structures. In our noncentral galaxies, the distribution of such gas is often concentrated, at variance with the more extended features observed in central galaxies. Misalignment between the multiphase gas and stars suggest that stellar mass loss is not the primary driver. A fraction of the cool gas might be acquired via galaxy interactions, but we do not find quantitative evidence of mergers in most of our systems. Instead, key evidence supports the origin via condensation out of the diffuse halo. Comparing with chaotic cold accretion (CCA) simulations, we find that our cool gas-free galaxies are likely in the overheated phase of the self-regulated AGN cycle, while for our galaxies with cool gas, the k-plot and AGN power correlation corroborate the phase of CCA feeding in which the condensation rain is triggering more vigorous AGN heating. The related C-ratio further shows that central/noncentral galaxies are expected to generate an extended/inner rain, consistent with our sample.
Numerical Convergence of 2D Solar Convection in Implicit Large-eddy Simulations

Published: April 2022

Large-eddy simulations (LES) and implicit LES (ILES) are wise and affordable alternatives to the unfeasible direct numerical simulations of turbulent flows at high Reynolds (Re) numbers. However, for systems with few observational constraints, it is a formidable challenge to determine if these strategies adequately capture the physics of the system. Here, we address this problem by analyzing numerical convergence of ILES of turbulent convection in 2D, with resolutions between 642 and 20482 grid points, along with the estimation of their effective viscosities, resulting in effective Reynolds numbers between 1 and ∼104. The thermodynamic structure of our model resembles the solar interior, including a fraction of the radiative zone and the convection zone. In the convective layer, the ILES solutions converge for the simulations with ≥5122 grid points, as evidenced by the integral properties of the flow and its power spectra. Most importantly, we found that even a resolution of 1282 grid points,

, is sufficient to capture the dynamics of the large scales accurately. This is a consequence of the ILES method allowing the energy contained in these scales to be the same in simulations with low and high resolution. Special attention is needed in regions with a small density scale height driving the formation of fine structures unresolved by the numerical grid. In the stable layer, we found the excitation of internal gravity waves, yet high resolution is needed to capture their development and interaction.

We investigate the formation of jellyfish galaxies using radiation-hydrodynamic simulations of gas-rich dwarf galaxies with a multiphase interstellar medium (ISM). We find that the ram-pressure-stripped (RPS) ISM is the dominant source of molecular clumps in the near wake within 10 kpc from the galactic plane, while in situ formation is the major channel for dense gas in the distant tail of the gas-rich galaxy. Only 20% of the molecular clumps in the near wake originate from the intracluster medium (ICM); however, the fraction reaches 50% in the clumps located at 80 kpc from the galactic center since the cooling time of the RPS gas tends to be short owing to the ISM–ICM mixing (≲10 Myr). The tail region exhibits a star formation rate of 0.001–0.01 M
⊙ yr−1, and most of the tail stars are born in the stripped wake within 10 kpc from the galactic plane. These stars induce bright Hα blobs in the tail, while Hα tails fainter than 6 × 1038 erg s−1 kpc−2 are mostly formed via collisional radiation and heating due to mixing. We also find that the stripped tails have intermediate X-ray-to-Hα surface brightness ratios (1.5 ≲ F
X/F
Hα
≲ 20), compared to the ISM (≲1.5) or pure ICM (≫20). Our results suggest that jellyfish features emerge when the ISM from gas-rich galaxies is stripped by strong ram pressure, mixes with the ICM, and enhances the cooling in the tail.
The Number of Possible CETIs within Our Galaxy and the Communication Probability among These CETIs
Authors: Song Wenjie , Gao He
Published: April 2022

As the only known intelligent civilization, human beings are always curious about the existence of other communicating extraterrestrial intelligent civilizations (CETIs). Based on the latest astrophysical information, we carry out Monte Carlo simulations to estimate the number of possible CETIs within our Galaxy and the communication probability among them. Two poorly known parameters have a great impact on the results. One is the probability of life appearing on terrestrial planets and eventually evolving into a CETI (f

c
), and the other determines at what stage of their host star’s evolution CETIs would be born (F). In order to ensure the completeness of the simulation, we consider a variety of combinations of f

c
and F. Our results indicate that for optimistic situations (e.g., F = 25% and f

c
= 0.1%), there could be

Methodology for Monitoring the Mobility of Circular Labour Migrants in Moscow Region
Authors: Shitova Yuliia
Published: April 2022

The paper presents the original author’s methodology for monitoring commuting labour migration in a region on the example of Moscow Region. The methodology is based on regular collection of real-time information from the Yandex.Probki platform on the regional transport network state by querying and saving travel time for a fixed set of car routes (basic sample) covering the region under study. An analysis of the data collected over the past two years enabled studying the structure and dynamics of travel time losses by commuting labour migrants. The time dynamics of losses are sensitive to events such as lockdowns and holidays. The estimates obtained show a stable cyclicity of travel time losses within a day and a week, which confirms the validity of the indicator proposed by the author. The study demonstrates that the loss of time on the commute during peak hours is 2.5 times higher than the loss when driving without traffic jams. In conclusion, the paper discusses the prospects for scaling the author’s methodology to any regions in which the Yandex.Probki platform is present.

Une meilleure rémunération des mineurs : un effet positif sur la performance financière des cryptomonnaies
Authors: Alfieri Elise , Ferrat Yann
Published: April 2022

Pour faire face au système financier fragilisé, l’écosystème innovant des cryptomonnaies et de la blockchain semble être une alternative. En plus d’une gouvernance décentralisée, les cryptomonnaies offrent une exposition aux dimensions sociales. Nous posons ainsi la question suivante : existe-t-il un cercle vertueux entre performance extra-financière et financière pour les cryptomonnaies ? Nous analysons ainsi la performance sociale, une dimension extra-financière, à travers la rémunération des mineurs. En utilisant un échantillon de cryptomonnaies entre 2015 et 2021, nous réalisons une analyse de portefeuille constitué en fonction de la rémunération des mineurs et utilisons un modèle en données de panel. Cette double approche permet d’étudier la relation à l’échelle macro et microéconomique, renforçant la robustesse des inférences. Nos résultats montrent que la relation performance sociale et boursière est positive. Ainsi, un partage de la valeur ajoutée accrue pour une cryptomonnaie semble être synonyme de performance financière plus élevée. Codes JEL : C58, G14, G19, M14
Critical realism based entrepreneurial action theory
Authors: Forsell Marko , Paloniemi Kaarlo
Published: April 2022

We propose to use critical realism as the basis for ontology and epistemology in entrepreneurship research. Further, we argue that the teleology of entrepreneurship is value creation. Based on these assumptions we propose that an essential part of the entrepreneurial process is the creation of a business model that shows conceptually how the value will be created. This model can be categorized in three different categories along with the value system continuum: stable value system, redefined value system and emerging value system. We propose an entrepreneurial value creation framework that describes elements that are essential to the value creation.

This is a conceptual paper in exploring the differences in decision making process between family business and non-family business in the construction industry in Malaysia. The understanding of the complexity and dynamics of a family business is becoming more prevalent among researchers. Fast decision making is not only seen as necessary but crucial to ensure speed and efficiency in responding to market opportunities and maneuvering through market uncertainties and tumultuous environment, with the intention to diversify their businesses by finding opportunities towards new venture creation. This study intends to suggest how to simplify decision making and find tactics to have quality decision making. Hence, this study will focus primarily on the decision making process which is mapped against the Bayesian causal map.

MOpA©: A Multiple Opportunity Screening Heuristic for Entrepreneurs
Authors: Lynch IV Thomas J.
Published: April 2022

Much of the opportunity assessment literature focuses on evaluating a single opportunity rather than multiple opportunities. However, discussions with entrepreneurs, as well as personal experience, suggests that many entrepreneurs have multiple opportunities that they are screening in parallel. As such, the challenge is to assess each opportunity for its viability individually and against other opportunities under review. A second challenge is retaining objectivity in the opportunity assessment process. More than one entrepreneur, including one of the authors, spoke of how particular opportunities resonated with them, even before any research had been conducted. If entrepreneurs have a means to evaluate multiple opportunities objectively, they will have a much more realistic view of which opportunities have the highest potential for success. The authors explored how opportunities are analyzed, then modeled the process for multiple opportunities and developed a heuristic to assist entrepreneurs with the effort. The Multiple Opportunity Analysis Process (MOpA©) was pre-tested with students in undergraduate and postgraduate entrepreneurship courses, and with entrepreneurs. After making appropriate changes, a single case study was conducted in which one entrepreneur’s multiple opportunities were assessed. The heuristic proved to be viable at narrowing the opportunities quickly to a much smaller set, as well as identifying the best alternative. To the authors’ knowledge, this heuristic is the only one of its type, and, with further testing, may hold significant value for the field.
