SOCIAL CONFLICT: ARCHETYPAL NATURE AND RESOLUTION MECHANISM
Authors: Hasanov Ruslan Rafisovich 
Published: June 2018

On the basis of the archetypic analysis of development trends of a conflictological paradigm the author’s model of minimization of conflict potential in modern society is offered. Institutional construction is the basis for model that is harmonized with a factor of societal identity.
It is noted that the problems of social conflicts, according to data from monitoring studies of the Ukrainian school of archetype, are increasingly shifted into the sphere of interpersonal relations. It is stimulated by the progression in society of so-called self-sufficient personalities, the “subjectification” of the social space, and at the same time narrowing down to the solution of entirely specific situations in which there is a collision of the interests of two or more parties.
Instead, in order to find the optimal solution for resolving the conflict, it is necessary to have interdisciplinary knowledge, in particular understanding of the deep nature of such conflicts. Collision of points of view, thoughts, positions — a very frequent phenomenon of modern social life. In order to develop the correct line of behavior in various conflict situations, it is important to adequately understand the nature of the emergence of the modern conflict and the mechanisms for resolving them in substance. Knowledge of conflict nature enriches the culture of communication and makes human life and social groups not only more calm, but also creates conditions for constructive development. It is proved that in modern life one can not but agree with the statement that an individual carries first responsibility for his own life and only then for the life of the social groups to which he belongs. And while making decisions within the framework of modern mechanisms (consensus), the properties of human psychology such as extroversion, emotionality, irrationality, intuition, externality, and executive ability will not at least contribute to such a task.
That is why in the author’s research attracted attention to the archetypal nature of the conflict — the primitive images, ideas, feelings inherent in man as a bearer of the collective unconscious.
PUBLIC REGULATION OF COOPERATION WITH INTERNATIONAL FINANCIAL ORGANIZATIONS: EXPERIENCE OF THE COUNTRIES OF EASTERN EUROPE
Authors: Shostak Svetlana Nikolaevna 
Published: June 2018

The article analyzes the effectiveness of the activities of international financial organizations in the context of their cooperation with the countries of Eastern Europe. The article clarifies that financing by international financial organizations of the private sector of Eastern Europe creates preconditions for raising their economic and social efficiency and for creating not only collective but also social goods. The main goals of the Eastern European countries, financed by international financial organizations, are considered in detail.
It is proved that the financing of the private sector of the Eastern European countries of the EBRD creates the preconditions for raising their economic and social efficiency and for creating not only collective but also public goods. However, the implementation of these prerequisites depends on a sound economic policy of the country, the timely formation of a new institutional structure for the functioning of the public sector, etc. It is noted that for the effective provision of this area of cooperation with the EBRD to the countries of Eastern Europe it is necessary:
• facilitate the transition from the capital and labor-intensive export of industrial products to high-tech and innovative; • to provide state aid for the formation of foreign capital by creating special zones of export production with a favorable tax regime; • implement a planned approach to regulating the development of the national economy on the basis of optimization of the state procurement process, the formation of subsidies and other forms of state regulation of investment activity, etc.
It is noted that in general, the experience of cooperation of the countries of Eastern Europe with international financial organizations and for Ukraine is important. After all, in Ukraine there are a number of political factors that hinder the development of foreign investments due to the non-adaptation of domestic enterprises to the world market conditions of cooperation. In order to solve this problem, it is necessary to reorganize the structure of state management of industrial objects and to establish mechanisms for legislative regulation of this process.
Two Procedures to Flag Radio Frequency Interference in the UV Plane
Authors: Sekhar Srikrishna , Athreya Ramana 
Published: June 2018

Abstract
We present two algorithms to identify and flag radio frequency interference (RFI) in radio interferometric imaging data. The first algorithm utilizes the redundancy of visibilities inside a UV cell in the visibility plane to identify corrupted data, while varying the detection threshold in accordance with the observed reduction in noise with radial UV distance. In the second algorithm, we propose a scheme to detect faint RFI in the visibility time-channel (TC) plane of baselines. The efficacy of identifying RFI in the residual visibilities is reduced by the presence of ripples due to inaccurate subtraction of the strongest sources. This can be due to several reasons including primary beam asymmetries and other direction-dependent calibration errors. We eliminated these ripples by clipping the corresponding peaks in the associated Fourier plane. RFI was detected in the ripple-free TC plane but was flagged in the original visibilities. Application of these two algorithms to five different 150 MHz data sets from the GMRT resulted in a reduction in image noise of 20%–50% throughout the field along with a reduction in systematics and a corresponding increase in the number of detected sources. However, in comparing the mean flux densities before and after flagging RFI, we find a differential change with the fainter sources (25σ < S < 100 mJy) showing a change of −6% to +1% relative to the stronger sources (S > 100 mJy). We are unable to explain this effect, but it could be related to the CLEAN bias known for interferometers.
MIKiS: The Multi-instrument Kinematic Survey of Galactic Globular Clusters. I. Velocity Dispersion Profiles and Rotation Signals of 11 Globular Clusters*

Abstract
We present the first results of the Multi-Instrument Kinematic Survey of Galactic Globular Clusters (GGCs), a project aimed at exploring the internal kinematics of a representative sample of GGCs from the radial velocity of individual stars, covering the entire radial extension of each system. This is achieved by exploiting the formidable combination of multi-object and integral field unit spectroscopic facilities of the ESO Very Large Telescope. As a first step, here we discuss the results obtained for 11 clusters from high and medium resolution spectra acquired through a combination of FLAMES and KMOS observations. We provide the first kinematical characterization of NGC 1261 and NGC 6496. In all the surveyed systems, the velocity dispersion profile declines at increasing radii, in agreement with the expectation from the King model that best fits the density/luminosity profile. In the majority of the surveyed systems, we find evidence of rotation within a few half-mass radii from the center. These results are in general overall agreement with the predictions of recent theoretical studies, suggesting that the detected signals could be the relic of significant internal rotation set at the epoch of the cluster’s formation.
Optical High-resolution Spectroscopy of 14 Young α-rich Stars∗
Authors: Matsuno Tadafumi , Yong David , Aoki Wako , Ishigaki Miho N. 
Published: June 2018

Abstract
We report chemical abundances of 14 young α-rich stars including neutron-capture elements based on high-quality optical spectra from HIRES/Keck I and differential line-by-line analysis. From a comparison of the abundance patterns of young α-rich stars to those of nearby bright red giants with a similar metallicity range (−0.7 < [Fe/H] < −0.2), we confirm their high α-element abundances reported by previous studies based on near-infrared spectroscopy. We reveal for the first time low abundances of s-process elements and high abundances of r-process elements. All the abundances are consistent with those seen in the typical α-rich population of the Galactic disk, and no abundance anomalies are found except for Li-enhancement in one object previously reported and mild enhancement of Na in two stars. In particular, the lack of s-process enhancement excludes the hypothesis that mass transfer from asymptotic giant branch stars plays an important role in the formation of young α-rich stars. The high frequency of radial velocity variation (more than 50%) is also confirmed. We argue that mass transfer from low-mass red giants is the likely dominant formation mechanism for young α-rich stars.
Ionized Gas Motions and the Structure of Feedback near a Forming Globular Cluster in NGC 5253
Authors: Cohen Daniel P. , Turner Jean L. , Consiglio S. Michelle , Martin Emily C. , Beck Sara C. 
Published: June 2018

Abstract
We observed Brackett α 4.05 μm emission toward the supernebula in NGC 5253 with NIRSPEC on Keck II in adaptive optics mode, NIRSPAO, to probe feedback from its exciting embedded super star cluster (SSC). NIRSPEC's Slit-viewing Camera was simultaneously used to image the K-band continuum at ∼0.″1 resolution. We register the IR continuum with HST imaging, and find that the visible clusters are offset from the K-band peak, which coincides with the Brα peak of the supernebula and its associated molecular cloud. The spectra of the supernebula exhibit Brα emission with a strong, narrow core. The linewidths are 65–76 km s−1, FWHM, comparable to those around individual ultra-compact H ii regions within our Galaxy. A weak, broad (FWHM ≃ 150–175 km s−1) component is detected on the base of the line, which could trace a population of sources with high-velocity winds. The core velocity of Brα emission shifts by +13 km s−1 from NE to SW across the supernebula, possibly indicating a bipolar outflow from an embedded object or a link to a foreground redshifted gas filament. The results can be explained if the supernebula comprises thousands of ionized wind regions around individual massive stars, stalled in their expansion due to critical radiative cooling and unable to merge to drive a coherent cluster wind. Based on the absence of an outflow with large mass loss, we conclude that feedback is currently ineffective at dispersing gas, and the SSC retains enriched material out of which it may continue to form stars.
Generation of Optical Vortices by Nonlinear Inverse Thomson Scattering at Arbitrary Angle Interactions
Authors: Taira Yoshitaka , Katoh Masahiro 
Published: June 2018

Abstract
We theoretically verify that optical vortices carrying orbital angular momentum are generated in various astrophysical situations via nonlinear inverse Thomson scattering. Arbitrary angle collisions between relativistic electrons and circularly polarized strong electromagnetic waves are treated. We reveal that the higher harmonic components of scattered photons carry well-defined orbital angular momentum under a specific condition that the Lorentz factor of the electron is much larger than the field strength parameter of the electromagnetic wave. Our study indicates that optical vortices in a wide frequency range from radio waves to gamma-rays are naturally generated in environments where high-energy electrons interact with circularly polarized strong electromagnetic waves at various interaction angles. Optical vortices should be a new multi-messenger member carrying information concerning the physical circumstances of their sources, e.g., the magnetic and radiation fields. Moreover, their interactions with matter via their orbital angular momenta may play an important role in the evolution of matter in the universe.
Gamma-Ray Burst Optical Afterglows with Two-component Jets: Polarization Evolution Revisited
Authors: Lan Mi-Xiang , Wu Xue-Feng , Dai Zi-Gao 
Published: June 2018

Abstract
Gamma-ray bursts have been widely argued to originate from binary compact object mergers or core collapse of massive stars. Jets from these systems may have two components: an inner, narrow sub-jet and an outer, wider sub-jet. Such a jet subsequently interacts with its ambient gas, leading to a reverse shock (RS) and a forward shock. The magnetic field in the narrow sub-jet is very likely to be mixed by an ordered component and a random component during the afterglow phase. In this paper, we calculate light curves and polarization evolution of optical afterglows with this mixed magnetic field in the RS region of the narrow sub-jet in a two-component jet model. The resultant light curve has two peaks: an early peak arising from the narrow sub-jet and a late-time rebrightening due to the wider sub-jet. We find the polarization degree (PD) evolution under such a mixed magnetic field confined in the shock plane is very similar to that under the purely ordered magnetic field condition. The two-dimensional “mixed” magnetic fields confined in the shock plane are essentially the ordered magnetic fields only with different configurations. The position angle (PA) of the two-component jet can change gradually or abruptly by 90°. In particular, an abrupt 90° change of the PA occurs when the PD changes from its decline phase to the rise phase.
BANYAN. XII. New Members of Nearby Young Associations from GAIA–Tycho Data
Authors: Gagné Jonathan , Roy-Loubier Olivier , Faherty Jacqueline K. , Doyon René , Malo Lison 
Published: June 2018

Abstract
We present a search for stellar members of young associations within 150 pc of the Sun, based on TGAS and an updated version of the BANYAN Σ software to determine Bayesian membership probabilities that includes Gaia–2MASS color-magnitude diagrams. We identify 32 new F0–M3-type bona fide members of the 10–200 Myr old Sco-Cen, Carina, Tucana-Horologium, Columba, and Octans associations and the AB Doradus, β Pictoris, and Carina-Near moving groups. These new bona fide members have measurements of their full kinematics and literature data consistent with a young age. We also confirm the membership of 66 previously known candidate members using their Gaia–Tycho trigonometric distances or new literature radial velocities, and identify 219 additional new candidate members, most of which do not yet have a radial velocity measurement. This work is the first step toward a completeness-corrected survey of young association members based on Gaia DR2 in the near future.
Spinup and Disruption of Interstellar Asteroids by Mechanical Torques, and Implications for 1I/2017 U1 (‘Oumuamua)
Authors: Hoang Thiem , Loeb Abraham , Lazarian A. , Cho Jungyeon 
Published: June 2018

Abstract
The discovery of the first interstellar asteroid, 1I/2017 U1 (‘Oumuamua), has opened a new era for research on interstellar objects. In this paper, we study the rotational dynamics of interstellar asteroids (ISAs) of irregular shapes moving through the interstellar gas. We find that regular mechanical torques resulting from the bombardment of gas flow on the irregular body could be important for the dynamics and destruction of ISAs. Mechanical torques can spin up the ISA, resulting in the breakup of the original ISA into small binary asteroids when the rotation rate exceeds the critical frequency. We find that the breakup timescale is short for ISAs of highly irregular shapes and low tensile strength. We apply our results to the first observed ISA, ‘Oumuamua, and suggest that its extreme elongated shape may originate from a reassembly of the binary fragments, due to gravity along its journey in the interstellar medium. The tumbling of ‘Oumuamua could have been induced by rotational disruption due to mechanical torques. Finally, we discuss the survival possibility of high-velocity asteroids presumably formed by tidal disruption of planetary systems by the black hole at the Galactic center.

Published: June 2018

Abstract
We present the first results from our survey of intervening and proximate Lyman limit systems (LLSs) at z ∼ 2.0–2.5 using the Wide Field Camera 3 on board the Hubble Space Telescope. The quasars in our sample are projected pairs with proper transverse separations R
⊥ ≤ 150 kpc and line-of-sight velocity separations ≲11,000 km s−1. We construct a stacked ultraviolet (rest-frame wavelengths 700–2000 Å) spectrum of pairs corrected for the intervening Lyman forest and Lyman continuum absorption. The observed spectral composite presents a moderate flux excess for the most prominent broad emission lines, a ∼30% decrease in flux at λ = 800–900 Å compared to a stack of brighter quasars not in pairs at similar redshifts, and lower values of the mean free path of the H i ionizing radiation for pairs (

= 140.7 ± 20.2

Mpc) compared to single quasars (

= 213.8 ± 28

Mpc) at the average redshift z ≃ 2.44. From the modeling of LLS absorption in these pairs, we find a higher (∼20%) incidence of proximate LLSs with log

≥ 17.2 at δv < 5000 km s−1 compared to single quasars (∼6%). These two rates are different at the 5σ level. Moreover, we find that optically thick absorbers are equally shared between foreground and background quasars. Based on these pieces of evidence, we conclude that there is a moderate excess of gas-absorbing Lyman continuum photons in our closely projected quasar pairs compared to single quasars. We argue that this gas arises mostly within large-scale structures or partially neutral regions inside the dark matter halos where these close pairs reside.

Published: June 2018

PURPOSE:To assess psychometric properties of the Hong Kong Quality of Life Questionnaire (HKQ) using Rasch analysis and use it to assess cataract surgery outcomes.METHODS:The HKQ was interviewer administered to participants at baseline (preoperative) and 12 months of follow-up (postoperative). Rasch analysis was used to assess and improve psychometric properties of the HKQ using the preoperative data. The responsiveness of the HKQ was assessed on the stacked preoperative and postoperative data, reported with the effect size.RESULTS:One hundred ninety-nine participants (median age: 72 years; interquartile range: 65 to 78 years) with cataract completed the HKQ at the preoperative assessment. There were more women (58%) and most of the participants had bilateral cataract (83.9%). Nearly half of the participants had undergone surgery in one eye (45.2%) followed by bilateral surgery (38.7%). Psychometric assessment guided by Rasch analysis resulted into a 15-item HKQ with promising psychometric properties including adequate measurement precision (2.09), no misfitting items, near perfect targeting (−0.05), unidimensionality, and with no evidence of item bias. For those who completed the HKQ (n = 82, 41.2%) at the 12-month follow-up visit, all groups demonstrated statistically significant gains in the HKQ scores, with the highest gain in participants who had undergone bilateral surgery (effect size: 2.61).CONCLUSIONS:The 15-item HKQ was valid and psychometrically sound and might be a highly responsive instrument to measure cataract surgery outcomes in China. This study demonstrated that cataract surgery significantly improves quality of life in the Chinese population.[J Refract Surg.2018;34(6):413–418.]
Long-term Results of Corneal Cross-linking for Terrien's Marginal Degeneration
Authors: Lamarca José , Salvador-Culla Borja , Fernández-Vega Carlos , Barraquer Rafael I. 
Published: June 2018

PURPOSE:
To report the long-term clinical outcomes of a patient with Terrien's marginal degeneration who underwent successful peripheral corneal cross-linking (CXL) to arrest progression.

METHODS:

Clinical assessment included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), corneal topography, anterior segment optical coherence tomography, ultrasonic pachymetry, corneal hysteresis, and corneal resistance factor. Eccentric epithelium-off CXL was performed in both eyes after limbal conjunctival resection. Following the Dresden protocol, fluence irradiation was set at 5.4 J/cm
2
, using 3 mW/cm
2
for a total exposure time of 30 minutes.

RESULTS:

Nine years of postoperative follow-up showed significant bilateral improvement in visual acuity, refraction, and corneal topography with no signs of progression of Terrien's marginal degeneration. In the right eye, UDVA improved from 0.05 to 0.3 decimal and CDVA from 0.8 to 1.2 decimal, cylinder was reduced from −14.00 to −3.00 diopters (D), simulated keratometry improved from 10.50 to 3.70 D, and the thinnest point on pachymetry remained almost unchanged (from 483 to 469
μ
m). In the left eye, UDVA improved from 0.1 to 0.2 decimal and CDVA remained unchanged at 1.2 decimal, cylinder was reduced from −6.00 to −2.75 D, simulated keratometry improved from 5.60 to 3.30 D, and the thinnest point on pachymetry remained stable at 486
μ
m.

CONCLUSIONS:
Eccentric peripheral CXL can be a safe, noninvasive alternative therapeutic approach for the management of Terrien's marginal degeneration with peripheral thinning.
