Balancing Work Life and Family Life: Problems and Remedies
Authors: Nepali Tej Narayan Prasad 
Published: June 2018

Work- family balance” is a term that refers to an individual’s perceptions of the degree to which s/he is experiencing positive relationships between work and family roles, where the relationships are viewed as compatible and at equilibrium with each other. Like a fulcrum measuring the daily shifting weights of time and energy allocation between work and family life, the term, “workfamily balance,” provides a metaphor to countervail the historical notion that work and family relationships can often be competing, at odds, and conflicting.There was a time when the boundaries between work and home were fairly clear. Today, however, work is likely to invade our personal life — and maintaining work-life balance is no simple task. Family work balance is a complex issue that involves financial values, gender roles, career path, time management and many other factors. Every person and couple will have their own preferences and needs. The problem of maintaining a balance between work life and family life is not a new one. But in the recent few years social scientists have started paying more attention to it. Now there is growing concern in Nepal and experts are of the view that a constant struggle to balance both sets of life will have serious implications on the health of an employee.The seriousness of this problem increases many times in the cases of women workers in our society which is a traditional one and where women are still supposed to have greater family responsibilities. They are expected to look after their children, entertaining the guest, taking care of their parents, in laws and other elderly members of their families as also managing kitchen and other household affairs. Neglecting any of these responsibilities for the sake of discharging work in office or in other institutions where they are employed is not tolerated by their husbands and other male members of the society. We talk of women empowerment but we fail to understand the problems which working women are facing in the tradition bound society like of ours. The study is a pioneering work to investigate into this problem. It is a modest attempt to understand the manner in which women workers try to maintain balance between their work and family lives. The study also explores the ways and means by which female workers can be enabled to maintain proper balance between the two sets of their lives. The findings of this study may be of great use to employers, and business executives as well, who have now come to realize that the responsibility to maintain a healthy work life balance rests on both the organisation and employee.

Published: June 2018

BackgroundUp to half of patients with dementia may not receive a formal diagnosis, limiting access to appropriate services. It is hypothesised that it may be possible to identify undiagnosed dementia from a profile of symptoms recorded in routine clinical practice.AimThe aim of this study is to develop a machine learning-based model that could be used in general practice to detect dementia from routinely collected NHS data. The model would be a useful tool for identifying people who may be living with dementia but have not been formally diagnosed.Design & settingThe study involved a case-control design and analysis of primary care data routinely collected over a 2-year period. Dementia diagnosed during the study period was compared to no diagnosis of dementia during the same period using pseudonymised routinely collected primary care clinical data.MethodRoutinely collected Read-encoded data were obtained from 18 consenting GP surgeries across Devon, for 26 483 patients aged >65 years. The authors determined Read codes assigned to patients that may contribute to dementia risk. These codes were used as features to train a machine-learning classification model to identify patients that may have underlying dementia.ResultsThe model obtained sensitivity and specificity values of 84.47% and 86.67%, respectively.ConclusionThe results show that routinely collected primary care data may be used to identify undiagnosed dementia. The methodology is promising and, if successfully developed and deployed, may help to increase dementia diagnosis in primary care.
Laboratory Rotational Spectra of Silyl Isocyanide

Published: June 2018

Abstract
The rotational spectrum of silyl isocyanide (SiH3NC), an isomer of the well-studied silyl cyanide (SiH3CN), has been detected in the laboratory in a supersonic molecular beam, and the identification was confirmed by observations of the corresponding rotational transitions in the rare isotopic species

and SiH3N13C. Spectroscopic constants derived from 19 transitions between 11 and 35 GHz in the three lowest harmonically related rotational transitions in the K = 0 and 1 ladders of the normal isotopic species including the nitrogen nuclear quadrupole hyperfine constant allow the principal astronomical transitions of SiH3NC to be calculated to an uncertainty of about 4 km s−1 in equivalent radial velocity, or within the FWHM of narrow spectral features in the inner region of IRC+10216 near 200 GHz. The concentration of SiH3NC in our molecular beam is three times less than SiH3CN, or about the same as the corresponding ratio of the isomeric pair SiNC and SiCN produced under similar conditions. Silyl isocyanide is an excellent candidate for astronomical detection, because the spectroscopic and chemical properties are very similar to SiH3CN, which was recently identified in the circumstellar envelope of IRC+10216 by Cernicharo et al. and of SiNC and SiCN in the same source.

Abstract
We present structural parameters from a wide-field homogeneous imaging survey of Milky Way satellites carried out with the MegaCam imagers on the 3.6 m Canada–France–Hawaii Telescope and 6.5 m Magellan-Clay telescope. Our survey targets an unbiased sample of “outer halo” satellites (i.e., substructures having galactocentric distances greater than 25 kpc) and includes classical dSph galaxies, ultra-faint dwarfs, and remote globular clusters. We combine deep, panoramic gr imaging for 44 satellites and archival gr imaging for 14 additional objects (primarily obtained with the DECam instrument as part of the Dark Energy Survey) to measure photometric and structural parameters for 58 outer halo satellites. This is the largest and most uniform analysis of Milky Way satellites undertaken to date and represents roughly three-quarters (58/81 ≃ 72%) of all known outer halo satellites. We use a maximum-likelihood method to fit four density laws to each object in our survey: exponential, Plummer, King, and Sérsic models. We systematically examine the isodensity contour maps and color–magnitude diagrams for each of our program objects, present a comparison with previous results, and tabulate our best-fit photometric and structural parameters, including ellipticities, position angles, effective radii, Sérsic indices, absolute magnitudes, and surface brightness measurements. We investigate the distribution of outer halo satellites in the size–magnitude diagram and show that the current sample of outer halo substructures spans a wide range in effective radius, luminosity, and surface brightness, with little evidence for a clean separation into star cluster and galaxy populations at the faintest luminosities and surface brightnesses.

Published: June 2018

Abstract
The very high energy gamma-ray emission reported from a number of pulsar wind nebulae (PWNe) is naturally explained by the inverse Compton scattering of multi-TeV electrons. However, the physical dimensions of some gamma-ray-emitting PWNe significantly exceed the scales anticipated by the standard hydrodynamical paradigm of PWN formation. The most “disturbing” case in this regard is HESS J1825-137, which extends to distances of r ≈ 70 pc from the central pulsar PSR J1826−1334. If the gamma-ray emission is indeed produced inside the PWN, but not by electrons that escaped the nebula and diffuse in the interstellar medium (ISM), the formation of such an anomalously extended plerion could be realized, in a diluted environment with the hydrogen number density

. In this paper, we explore an alternative scenario assuming that the pulsar responsible for the formation of the nebula initially had a very short rotation period. In this case, the sizes of both the PWN and the surrounding supernova remnant depend on the initial pulsar period, the braking index, and the ISM density. To check the feasibility of this scenario, we study the parameter space that would reproduce the size of HESS J1825-137. We show that this demand can be achieved if the braking index is small,

, and the pulsar birth period is short,

. This scenario can reproduce the wind termination position, which is expected at

An Analytic Formulation of the 21 cm Signal from the Early Phase of the Epoch of Reionization
Authors: Raste Janakee , Sethi Shiv 
Published: June 2018

Abstract
We present an analytic formulation to model the fluctuating component of the H i signal from the epoch of reionization during the phase of partial heating. During this phase, we assume self-ionized regions, whose size distribution can be computed using excursion set formalism, to be surrounded by heated regions. We model the evolution of the heating profile around these regions (near zone) and their merger into the time-dependent background (far zone). We develop a formalism to compute the two-point correlation function for this topology, taking into account the heating autocorrelation and heating-ionization cross-correlation. We model the ionization and X-ray heating using four parameters: efficiency of ionization, ζ; number of X-ray photons per stellar baryon, N
heat; spectral index of X-ray photons, α; and minimum frequency of X-ray photons, ν
min. We compute the H i signal in the redshift range 10 < z < 20 for the ΛCDM model for a set of these parameters. We show that the H i signal for a range of scales 1–8 Mpc shows a peak strength of 100–1000 (mK)2 during the partially heated era. The redshift at which the signal makes a transition to a uniformly heated universe depends on the modeling parameters; e.g., if ν
min is changed from 100 eV to 1 keV, this transition moves from z ≃ 15 to z ≃ 12. This result, along with the dependence of the H i signal on the modeling parameters, is in reasonable agreement with existing results from N-body simulations.
Quasi-periodic Counter-propagating Fast Magnetosonic Wave Trains from Neighboring Flares: SDO/AIA Observations and 3D MHD Modeling
Authors: Ofman Leon , Liu Wei 
Published: June 2018

Abstract
Since their discovery by the Solar Dynamics Observatory/Atmospheric Imaging Assembly (AIA) in the extreme ultraviolet, rapid (phase speeds of ∼1000 km s−1), quasi-periodic, fast-mode propagating (QFP) wave trains have been observed accompanying many solar flares. They typically propagate in funnel-like structures associated with the expanding magnetic field topology of the active regions (ARs). The waves provide information on the associated flare pulsations and the magnetic structure through coronal seismology (CS). The reported waves usually originate from a single localized source associated with the flare. Here we report the first detection of counter-propagating QFPs associated with two neighboring flares on 2013 May 22, apparently connected by large-scale, trans-equatorial coronal loops. We present the first results of a 3D MHD model of counter-propagating QFPs in an idealized bipolar AR. We investigate the excitation, propagation, nonlinearity, and interaction of the counter-propagating waves for a range of key model parameters, such as the properties of the sources and the background magnetic structure. In addition to QFPs, we also find evidence of trapped fast- (kink) and slow-mode waves associated with the event. We apply CS to determine the magnetic field strength in an oscillating loop during the event. Our model results are in qualitative agreement with the AIA-observed counter-propagating waves and used to identify the various MHD wave modes associated with the observed event, providing insights into their linear and nonlinear interactions. Our observations provide the first direct evidence of counter-propagating fast magnetosonic waves that can potentially lead to turbulent cascade and carry significant energy flux for coronal heating in low-corona magnetic structures.
Stochastic Reconnection for Large Magnetic Prandtl Numbers
Authors: Jafari Amir , Vishniac Ethan T. , Kowal Grzegorz , Lazarian Alex 
Published: June 2018

Abstract
We consider stochastic magnetic reconnection in high-β plasmas with large magnetic Prandtl numbers, Pr
m
> 1. For large Pr
m
, field line stochasticity is suppressed at very small scales, impeding diffusion. In addition, viscosity suppresses very small-scale differential motions and therefore also the local reconnection. Here we consider the effect of high magnetic Prandtl numbers on the global reconnection rate in a turbulent medium and provide a diffusion equation for the magnetic field lines considering both resistive and viscous dissipation. We find that the width of the outflow region is unaffected unless Pr
m
is exponentially larger than the Reynolds number Re. The ejection velocity of matter from the reconnection region is also unaffected by viscosity unless Re ∼ 1. By these criteria the reconnection rate in typical astrophysical systems is almost independent of viscosity. This remains true for reconnection in quiet environments where current sheet instabilities drive reconnection. However, if Pr
m
> 1, viscosity can suppress small-scale reconnection events near and below the Kolmogorov or viscous damping scale. This will produce a threshold for the suppression of large-scale reconnection by viscosity when

. In any case, for Pr
m
> 1 this leads to a flattening of the magnetic fluctuation power spectrum, so that its spectral index is ∼−4/3 for length scales between the viscous dissipation scale and eddies larger by roughly

. Current numerical simulations are insensitive to this effect. We suggest that the dependence of reconnection on viscosity in these simulations may be due to insufficient resolution for the turbulent inertial range rather than a guide to the large Re limit.
Tracking Filament Evolution in the Low Solar Corona Using Remote Sensing and In Situ Observations
Authors: Kocher Manan , Landi Enrico , Lepri Susan. T. 
Published: June 2018

Abstract
In the present work, we analyze a filament eruption associated with an interplanetary coronal mass ejection that arrived at L1 on 2011 August 5. In multiwavelength Solar Dynamic Observatory/Advanced Imaging Assembly (AIA) images, three plasma parcels within the filament were tracked at high cadence along the solar corona. A novel absorption diagnostic technique was applied to the filament material traveling along the three chosen trajectories to compute the column density and temperature evolution in time. Kinematics of the filamentary material were estimated using STEREO/Extreme Ultraviolet Imager and STEREO/COR1 observations. The Michigan Ionization Code used inputs of these density, temperature, and speed profiles for the computation of ionization profiles of the filament plasma. Based on these measurements, we conclude that the core plasma was in near ionization equilibrium, and the ionization states were still evolving at the altitudes where they were visible in absorption in AIA images. Additionally, we report that the filament plasma was heterogeneous, and the filamentary material was continuously heated as it expanded in the low solar corona.
One Large Blob and Many Streams Frosting the nearby Stellar Halo in Gaia DR2

Published: June 2018

Abstract
We explore the phase-space structure of nearby halo stars identified kinematically from the Gaia second data release (DR2). We focus on their distribution in velocity and in “integrals of motion” space, as well as on their photometric properties. Our sample of stars selected to be moving at a relative velocity of at least 210 km s−1, with respect to the Local Standard of Rest, contains an important contribution from the low rotational velocity tail of the disk(s). The V

R
-distribution of these stars depicts a small asymmetry similar to that seen for the faster rotating thin disk stars near the Sun. We also identify a prominent, slightly retrograde “blob” that traces the metal-poor halo main sequence reported by Gaia Collaboration et al. We also find many small clumps that are especially noticeable in the tails of the velocity distribution of the stars in our sample. Their Hertzsprung–Russell (HR) diagrams disclose narrow sequences characteristic of simple stellar populations. This stream-frosting confirms predictions from cosmological simulations, namely that substructure is most apparent among the fastest moving stars, typically reflecting more recent accretion events.
Les pratiques sociales de référence en questions. Le cas du football en éducation physique et sportive
Authors: Hebert Thibaut 
Published: June 2018

Il s’agit d’analyser, à travers une enquête menée auprès d’enseignants d’EPS ( n = 86 ) et de collégiens ( n = 116 ), les représentations d’une des pratiques sociales les plus populaires, le football. Autrement dit, comment sont-elles connotées ? Influencent-elles les professeurs quant à leur manière d’aborder l’enseignement de cette activité ? Les résultats ont révélé globalement chez les enseignants moins d’affection à l’égard du football que chez les élèves. Dans un cadre scolaire, ils s’avèrent même peu enclins à son enseignement. Dans ce cas, le rapport à la règle et à l’autorité, la mixité lors d’une pratique masculine, ou encore la dichotomie entre la pratique des élèves en dehors de l’école (logique compétitive et individualiste) et celle attendue en EPS par les professeurs (logique de coopération) peuvent s’avérer autant de freins à sa mise en œuvre pédagogique.
Sur la logique des prépositions
Authors: Martin Robert 
Published: June 2018

Dans le prolongement de l’ouvrage intitulé Linguistique de l’universel (Martin, 2016), la présente réflexion vise à cerner la catégorie prépositionnelle dans une grammaire à fondement logique : c’est la préposition en tant que catégorie qui retient l’attention (notamment par opposition à la catégorie du cas) et non les contenus sémantiques que les prépositions comportent. À l’intérieur d’une proposition, l’opérateur prépositionnel, qui a toujours pour effet d’accroître le nombre des arguments, ou bien étend la transitivité verbale au-delà de ses limites, ou bien instaure des ordres de prédication au-delà des ordres que produisent les parties du discours fondamentales (substantif, adjectif, verbe, adverbe), la préposition générant alors une relation d’ordination supérieure d’un degré entre l’élément de type nominal qu’elle gouverne (avec lequel elle forme un syntagme prépositionnel) et un élément quelconque de la proposition (l’élément sur lequel porte le syntagme prépositionnel).
Population Demographics of Sauger and Simulated Effects of Minimum Length Limits in the Kaskaskia and Ohio Rivers

Published: June 2018

AbstractSauger Sander canadensis are a popular sport fish native to large turbid midwestern rivers and are in decline across much of their range due to habitat loss and exploitation. Specifically, within the lower Kaskaskia and Ohio rivers, Sauger are managed under different harvest regulations and a knowledge gap exists regarding the current status of both populations as well as the effects of the harvest regulations on the size and age structures of both populations. We collected Sauger by nighttime boat electrofishing during early winter 2014–2016 and used otoliths to age all fish. Sauger stocks in both rivers exhibited fast growth rates and high annual mortality rates. Yield-per-recruit modeling indicated that the current 356-mm minimum size limit for Sauger in the Kaskaskia River is sufficient to prevent growth overfishing and likely explains the consistently larger size structure (greater proportion of fish ≥356-mm total length) of Sauger sampled from the Kaskaskia River compared with the Ohio River. Modeling suggested that growth and recruitment overfishing of Sauger are likely occurring in the Ohio River with no minimum length limit based on available exploitation estimates for Sauger in the lower Ohio River. Implementing a 356-mm minimum length limit for Sauger in the lower Ohio River is predicted to prevent growth and recruitment overfishing based on available exploitation rate estimates and would be consistent with the statewide minimum length limit for Sauger in Illinois and minimum length limits on two major tributaries (Tennessee and Cumberland rivers downstream of Kentucky and Barkley lakes, respectively).
