To the Issue of the Methodology of Formation of Shipbuilding Programs in Russia
Authors: Alekhin M. Yu. , Titov A. V. 
Published: May 2020

The presented study addresses the need to change approaches to the formation of long-term shipbuilding programs in the Russian Federation and determines the place of such programs in the system of strategic management of the national economy.Aim. The study identifies efficient approaches to the formation of long-term shipbuilding programs in Russia with allowance for international experience and current political and economic conditions.Tasks. The authors analyze the existing methodological framework for the formation of shipbuilding programs in the Russian Federation; examine the shipbuilding development experience of South Korea, China, the US, and Ukraine; address the issue of improving the investment climate in the shipbuilding industry by changing the institutional conditions in closely related industries.Methods. This study’s scientific methodology is based on using general scientific methods of cognition, a systems approach to the problem, and comprehensive consideration of the issues of formation of industry programs with allowance for the specific features of shipbuilding.Results. Over the past decades, shipbuilding programs in the Russian Federation have been formed according to a methodological framework of questionable depth and insufficient sophistication. Successful development of shipbuilding in the world’s leading countries is largely due to the achievement of the required level of competence and technological advancement accumulated through the development of the domestic market, which is impossible without active state participation. Based on the analysis of positive and negative shipbuilding development experience of different countries and current trends in the Russian shipbuilding industry, it is possible to conclude that the success of shipbuilding development largely depends on the rules (institutional conditions) established by the state.Conclusions. The efficiency of investment processes in the industry can be improved by integrating the shipbuilding development program into a global program for the development of the marine economic complexes of the Russian Federation.
Size and shape constancy in consumer virtual reality
Authors: Hornsey Rebecca L. , Hibbard Paul B. , Scarfe Peter 
Published: May 2020

AbstractWith the increase in popularity of consumer virtual reality headsets, for research and other applications, it is important to understand the accuracy of 3D perception in VR. We investigated the perceptual accuracy of near-field virtual distances using a size and shape constancy task, in two commercially available devices. Participants wore either the HTC Vive or the Oculus Rift and adjusted the size of a virtual stimulus to match the geometric qualities (size and depth) of a physical stimulus they were able to refer to haptically. The judgments participants made allowed for an indirect measure of their perception of the egocentric, virtual distance to the stimuli. The data show under-constancy and are consistent with research from carefully calibrated psychophysical techniques. There was no difference in the degree of constancy found in the two headsets. We conclude that consumer virtual reality headsets provide a sufficiently high degree of accuracy in distance perception, to allow them to be used confidently in future experimental vision science, and other research applications in psychology.

Abstract
We report here time-domain infrared spectroscopy and optical photometry of the HD 145263 silica-rich circumstellar-disk system taken from 2003 through 2014. We find an F4V host star surrounded by a stable, massive 1022–1023 kg (M
Moon to M
Mars) dust disk. No disk gas was detected, and the primary star was seen rotating with a rapid ∼1.75 day period. After resolving a problem with previously reported observations, we find the silica, Mg-olivine, and Fe-pyroxene mineralogy of the dust disk to be stable throughout and very unusual compared to the ferromagnesian silicates typically found in primordial and debris disks. By comparison with mid-infrared spectral features of primitive solar system dust, we explore the possibility that HD 145263's circumstellar dust mineralogy occurred with preferential destruction of Fe-bearing olivines, metal sulfides, and water ice in an initially comet-like mineral mix and their replacement by Fe-bearing pyroxenes, amorphous pyroxene, and silica. We reject models based on vaporizing optical stellar megaflares, aqueous alteration, or giant hypervelocity impacts as unable to produce the observed mineralogy. Scenarios involving unusually high Si abundances are at odds with the normal stellar absorption near-infrared feature strengths for Mg, Fe, and Si. Models involving intense space weathering of a thin surface patina via moderate (T < 1300 K) heating and energetic ion sputtering due to a stellar super-flare from the F4V primary are consistent with the observations. The space-weathered patina should be reddened, contain copious amounts of nanophase Fe, and should be transient on timescales of decades unless replenished.
Magnetic Imprisonment of Dusty Pinballs by a Supernova Remnant
Authors: Fry Brian J. , Fields Brian D. , Ellis and John R. 
Published: May 2020

Abstract
Motivated by recent measurements of deposits of 60Fe on the ocean floor and the lunar surface, we model the transport of dust grains containing 60Fe from a near-Earth (i.e., within 100 pc) supernova (SN). We inject dust grains into the environment of an SN remnant (SNR) and trace their trajectories by applying a 1D hydrodynamic description assuming spherical symmetry to describe the plasma dynamics, and we include a rudimentary, 3D magnetic field description to examine its influence on charged dust grains. We assume the interstellar medium (ISM) magnetic fields are turbulent and are amplified by the SNR shock, while the SN wind and ejecta fields are negligible. We examine the various influences on the dust grains within the SNR to determine when/if the dust decouples from the plasma, how much it is sputtered, and where within the SNR the dust grains are located. We find that Rayleigh–Taylor instabilities are important for dust survival, as they influence the location of the SN’s reverse shock. We find that the presence of a magnetic field within the shocked ISM material limits the passage of SN dust grains, with the field either reflecting or trapping the grains within the heart of the SNR. These results have important implications for in situ 60Fe measurements and for dust evolution in SNRs generally.
Morpheus: A Deep Learning Framework for the Pixel-level Analysis of Astronomical Image Data
Authors: Hausen Ryan , Robertson Brant E. 
Published: May 2020

Abstract
We present Morpheus, a new model for generating pixel-level morphological classifications of astronomical sources. Morpheus leverages advances in deep learning to perform source detection, source segmentation, and morphological classification pixel-by-pixel via a semantic segmentation algorithm adopted from the field of computer vision. By utilizing morphological information about the flux of real astronomical sources during object detection, Morpheus shows resiliency to false-positive identifications of sources. We evaluate Morpheus by performing source detection, source segmentation, morphological classification on the Hubble Space Telescope data in the five CANDELS fields with a focus on the GOODS South field, and demonstrate a high completeness in recovering known GOODS South 3D-HST sources with H < 26 AB. We release the code publicly, provide online demonstrations, and present an interactive visualization of the Morpheus results in GOODS South.

Published: May 2020

Abstract
We report a simultaneous 44 and 95 GHz class I methanol maser survey toward 144 sources from the 95 GHz class I methanol maser catalog. The observations were made with the three telescopes of the Korean very long baseline interferometry network operating in single-dish mode. The detection rates are 89% at 44 GHz and 77% at 95 GHz. There are 106 new discoveries at 44 GHz. Comparing the previous 95 GHz detections with new observations of the same transitions made using the Purple Mountain Observatory 13.7 m radio telescope shows no clear evidence of variability on a timescale of six years. Emission from the 44 and 95 GHz transitions shows strong correlations in peak velocity, peak flux density, and integrated flux density, indicating that they are likely cospatial. We found that the peak flux density ratio

decreases as the 44 GHz peak flux density increases. We found that some class I methanol masers in our sample might be associated with infrared dark clouds, while others are associated with H ii regions, indicating that some sources occur at an early stage of high-mass star formation, while others are located toward more evolved sources.
La valeur d’existence du monde vivant selon les Inuits du Nunavik et les Occidentaux aux Kerguelen
Authors: Joliet Fabienne , Van Tilbeurgh Véronique , Atlan Anne 
Published: May 2020

Dans le contexte actuel de transition socio-écologique internationale, l’objectif de cet article est d’interroger la relation entre les humains et les autres vivants et choses naturelles dans les derniers espaces de vaste naturalité aux pôles. C’est à travers la notion de valeur d’existence que cette relation sera analysée dans ses retranchements chez les Inuits qui habitent le Nunavik en subarctique et les Occidentaux qui veillent sur les Kerguelen en subantarctique. Plus particulièrement, c’est la nature du lien qu’ils entretiennent avec les vivants non-humains et autres choses naturelles, et ses registres de valeurs qui sont étudiées. Ces enquêtes boréales et australes en zone protégée ou bien à ses abords montrent ainsi que ce qui prédomine, c’est le fait qu’il est attribué aux éléments naturels une valeur d’existence en fonction d’un esprit commun spirituel ou bien d’une enveloppe commune charnelle d’« être vivant ». Selon ces principes, les modalités prises par l’attribution de la valeur d’existence changent : les humains se concevant soit, comme une partie d’un ensemble au même titre que les autres vivants et choses naturelles ayant un esprit ou conscience, soit comme maîtres et protecteurs des autres vivants et choses naturelles, en tant qu’ayant une fonction dominante au sein d’« êtres vivants ». Dans cette perspective, le territoire joue un rôle spécifique favorisant l’existence même de cette valeur au-delà de ses fonctions de régulation couramment retenues.
Du « coup de foudre » à l’investissement : les propriétaires français d’établissements touristiques dans la médina de Fès (Maroc)
Authors: Joly Merryl 
Published: May 2020

Depuis le début des années 2000, la médina de Fès au Maroc s’inscrit dans les dynamiques urbaines, sociales et économiques des centres historiques marocains sous l’impulsion d’entrepreneurs occidentaux. Séduits par le cadre de vie et la possibilité de vivre « l’ambiance riad », les anciennes demeures des médinas marocaines sont devenues des biens immobiliers prisés. La plupart de ces entrepreneurs ont choisi de les réhabiliter et de les transformer à des fins touristiques ce qui implique la construction d’un ensemble de liens économiques et sociaux plus ou moins formels avec leur nouvel environnement. À partir du cas des propriétaires français d’établissements touristiques dans la médina de Fès, cet article cherche à comprendre comment leur activité économique conduit à créer de nouveaux rapports avec la société locale en jouant sur différents registres (implication, différenciation, distanciation). Il s’agira d’analyser ces rapports au regard des stratégies d’implantation de ces propriétaires et des stratégies de développement touristique qu’ils mettent en place pour pérenniser leur activité économique.
Genre et succession dans les PME familiales marocaines
Authors: Zerbet Rachida , Ouahi Lhoucine 
Published: May 2020

Au Maroc comme ailleurs, la contribution économique des PME familiales est importante, mais la pérennité de ces entreprises dépend du choix du successeur. Les femmes successeurs sont encore peu nombreuses par rapport aux hommes et les attentes normatives restent liées aux caractéristiques de la masculinité plutôt qu’à celles de la féminité. Au Maroc, les politiques de l’État en faveur de l’autonomisation des femmes dans les sphères économique et sociale, ont contribué positivement à l’amélioration des conditions des femmes, mais dans le domaine des affaires, les femmes ne représentent que 10 % du total des entrepreneurs et des obstacles socioculturels limitent leur accès à des postes de direction au sein des PME familiales. Actuellement, l’évolution des relations sociales au sein des familles et de la structure des carrières façonne la manière de ‘faire le genre’ (doing gender) dans les affaires et contribue à rendre les femmes davantage légitimes pour prendre la relève de l’entreprise familiale 1 . Mais nous savons encore très peu de choses sur la manière dont les féminités sont mises en œuvre par les femmes dans le contexte très particulier de la succession des PME familiales marocaines. Cette thématique essentielle fait l’objet de notre étude qualitative, qui analyse les récits de quatre cas de PME familiales marocaines dans la région du Souss. Son objectif principal est d’explorer l’effet du genre, en tant que construction sociale, sur les femmes successeurs des PME familiales marocaines.

Authors: Bordas Ameline , Gaulin Johan , Van Hassel Franck 
Published: May 2020

Johan Gaulin (Associé EY – Responsable du marché des entreprises familiales en France) et Franck Van Hassel (Associé EY – Responsable de la Direction de la fiscalité privée et des entreprises familiales – Paris) partagent leurs regards d’experts en tant qu’interlocuteurs privilégiés auprès des entreprises familiales françaises. Pour passer l’épreuve du temps, ces sociétés font face à des enjeux de développement, d’innovation, de croissance… À cela s’ajoutent les enjeux de gouvernance, de succession, de gestion d’entrées et de sorties des membres de la famille, de transmission de la culture entrepreneuriale. Ces sujets sont souvent tabous au sein de la famille et débouchent régulièrement sur une incapacité à anticiper les enjeux de transmission. C’est pourquoi l’accompagnement proposé par EY permet de proposer des solutions adaptées aux enjeux de l’entreprise et à chaque contexte familial.
Le corps des femmes dans la Tunisie postrévolutionnaire
Authors: Kréfa Abir , Majdoub Rania 
Published: May 2020

Pendant la révolution tunisienne, les usages du corps ont été divers : instrument de politisation et de publicisation à travers les immolations, les nombreuses grèves de la faim et autres souffrances, il a aussi fait l’objet de mobilisations propres. Des femmes, se revendiquant ou non féministes, ont ainsi réclamé la liberté de disposer de leur corps. Dans ce cadre se situent tout aussi bien les mobilisations contre les violences, en particulier sexuelles, que les revendications de se vêtir et/ou se dénuder comme elles l’entendent. L’article analyse, à partir d’entretiens et d’archives, les modalités et les enjeux d’une mobilisation contre le viol en Tunisie entre 2012 et 2014, au sein de laquelle les autrices ont été engagées. D’une part, il relativise la spontanéité de la mobilisation, tout en montrant les effets de l’événement révolutionnaire, qui a notamment permis la formation d’une nouvelle génération de féministes. D’autre part, il montre que les stratégies discursives des militantes, surtout des aînées, n’échappent pas à certaines ambivalences, si bien que le corps des femmes demeure aussi l’objet d’une bataille partisane.

Published: May 2020

PURPOSE:
To assess 3-year safety and efficacy of enhanced-fluence pulsed-light iontophoresis cross-linking (EF I-CXL) in patients with progressive keratoconus.

METHODS:

This prospective interventional pilot study included 24 eyes of 20 patients, with a mean age of 23.9 years (range: 15 to 36 years). Iontophoresis with riboflavin solution was used for stromal imbibition. The treatment energy was optimized at 30% (7 J/cm
2
) and ultraviolet-A power set at 18 mW/cm
2
× 6.28 minutes of pulsed-light on-off exposure, with a total irradiation time of 12.56 minutes. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), corneal tomography, and corneal optical coherence tomography (OCT) at baseline and 1, 3, 6, 12, 24, and 3 years postoperatively were evaluated.

RESULTS:

At 3 years, average UDVA decreased from 0.50 ± 0.10 to 0.36 ± 0.08 logMAR (
P
< .05), average maximum keratometry decreased from 52.94 ± 1.34 to 51.4 ± 1.49 diopters (D) (Delta: −1.40 ± 0.80 D;
P
< .05), average coma improved from 0.24 ± 0.05 to 0.12 ± 0.02 µm (
P
= .001), and symmetry index decreased from 4.22 ± 1.01 to 3.53 ± 0.90 D. Corneal OCT showed demarcation line detection at 285.8 ± 20.2 µm average depth in more than 80% at 1 month postoperatively.

CONCLUSIONS:
The 3-year results of EF I-CXL showed satisfactory I-CXL functional outcomes, increasing the visibility and the depth of demarcation line closer to epithelium-off standard CXL.

Burnout and Substance Use in Collegiate Athletic Trainers
Authors: Oglesby Leslie W. , Gallucci Andrew R. , Wynveen Christopher J. , Ylitalo Kelly R. , Benson Nicholas F. 
Published: May 2020

Context
The Smith Cognitive-Affective Model of Athletic Burnout suggests that athletic trainers (ATs) suffering from burnout may engage in substance use as a coping behavior. Increases in self-reported burnout symptoms are often associated with increases in heavy episodic drinking and tobacco use among various health care providers. However, this relationship has not been examined thoroughly.

Objective
To investigate the prevalence of substance use in ATs and identify relationships between symptoms of burnout and substance use among ATs.

Design
Cross-sectional study.

Setting
Web-based survey.

Patients or Other Participants
A total of 783 certified ATs working full time in the collegiate or university setting were sampled for this study. Graduate assistant and other part-time ATs were excluded. The survey was distributed via the National Athletic Trainers' Association membership directory e-mail broadcast service.

Main Outcome Measure(s)
A 100-item online questionnaire consisting of items from previously used scales was used for this study. The survey included the Maslach Burnout Inventory and questions on substance use from the Monitoring the Future study. Multiple regression analyses were performed to analyze the survey data. All independent (Maslach Burnout Inventory subscales) and dependent (use of alcohol, tobacco, and marijuana) variables were mapped to the Smith Cognitive-Affective Model of Athletic Burnout to determine which dimensions of burnout altered the odds of self-reported substance use.

Results
Almost half (46.3%) of participants admitted to at least 1 binge-drinking episode. However, the use of cigarettes, smokeless tobacco, marijuana, and energy drinks during the previous month was less pronounced in the sample. Emotional exhaustion (B = 0.008, P = .023) and personal accomplishment (B = −0.016, P = .02) were significantly correlated with binge drinking. Emotional exhaustion (Exp[B] = 1.017, P &lt; .001) was also significantly positively correlated with energy-drink consumption.

Conclusions
Some ATs engaged in heavy episodic drinking. Emotional exhaustion and a decreased sense of personal accomplishment were significantly correlated with this behavior.
Club cell protein 16 as a biomarker for early detection of silicosis
Authors: Naha Nibedita , Muhamed Jaseer C.J. , Pagdhune Avinash , Sarkar Bidisa , Sarkar Kamalesh 
Published: May 2020

Background & objectives:
Clinically silicosis is diagnosed by chest X-ray showing specific opacities along with history of silica dust exposure. Diagnosis is invariably made at an advanced or end stage when it is irreversible. Moreover, silicosis patients are susceptible to develop tuberculosis. Therefore, a suitable biomarker for early detection of silicosis is needed. This study evaluated the suitability of club cell protein (CC16) as a biomarker for early detection of silicosis.

Methods:
This pilot study included 121 individuals from X-ray-confirmed/advanced silicosis, moderate silica dust-exposed workers and healthy controls from western India. CC16 levels were quantified in serum samples through ELISA. Sensitivity and specificity of CC16 values at different cut-off points were calculated in both non-smokers and smokers.

Results:
Serum CC16 level was significantly (P<0.01) decreased in X-ray confirmed advanced silicosis patients (4.7±3.07 ng/ml) followed by moderately exposed workers (10.2±1.77 ng/ml) as compared to healthy non-exposed individuals (16.7±3.81 ng/ml). Tobacco smoking also caused a significant decrease of serum CC16 concentration in both healthy (10.2±1.12 ng/ml) and advanced silicosis workers (2.6±2.28 ng/ml) compared to non-smokers. Sensitivity and specificity of CC16 values were also found to be ≥83 per cent for screening all categories of individuals.

Interpretation & conclusions:
Because of high sensitivity and specificity, serum CC16 could be used as predictive biomarker for suspicion and early detection of silicosis, which would help in reducing/delaying premature deaths caused by silicosis. It would also control silicotuberculosis additionally.
