Published: March 2019

Purpose- The purpose of this study was to investigate the impact of nepotism & favoritism as a form of organization politics on HRM practices and employee performance.
Design/Methodology- Explanatory research design was employed to determine the effect of nepotism & favoritism on HRM practices and employee performance. Primary data collection method was used among employees working in different public-sector hospitals based on their accessibility. For this study, the sample of 150 employees was used. The adapted questionnaire was used for data collection. Data were analyzed using SPSS.
Findings- The correlation analysis revealed a significant relationship between favoritism, employee performance & HRM practices whereas nepotism has a significant association with employee performance but the insignificant relationship with HRM practices. The outcomes of the study unveiled a significantly negative effect of nepotism on employee performance & HRM practices while favoritism has a significantly positive effect on employee performance & HRM practices.
Practical Implications- The study outcomes might help public sector hospitals HR department to incorporate some changes regarding their policies to prevent the nepotistic & favoritism practices which can lead to creating a politics in the organization in which everyone works to fulfill his or her self- interest without focusing towards organizational goals achievement.

Objetivou-se investigar a atuação da atenção primária em saúde na rede de apoio social í gestante adolescente. Trata-se de uma pesquisa exploratório-descritiva, qualitativa, realizada com 16 gestantes entre 12 e 18 anos e com enfermeiros, de fevereiro a maio de 2014, em quatro Unidades de Atenção Primária í Saúde da cidade de Fortaleza/CE, além do domicí­lio das gestantes. Para a coleta dos dados com as gestantes, utilizou-se uma entrevista semiestruturada; para avaliar a atuação do enfermeiro nas consultas de pré-natal, realizou-se a observação sistemática. Da análise dos dados pela técnica de análise de conteúdo, emergiu a categoria O apoio social da Atenção Primária í Saúde na maternidade adolescente. Nenhuma participante possuí­a ví­nculo empregatí­cio e algumas relataram abandono dos estudos; mais da metade era casada/amasiada e todas afirmaram ser católicas. A rede de apoio social contribuiu significativamente para as gestantes adolescentes no enfrentamento das adversidades inerentes ao seu processo adaptativo í nova realidade. Contudo, percebeu-se que o pouco apoio social oriundo dos enfermeiros foi um ponto negativo, revelando ví­nculos frágeis e pouco efetivos na contribuição da adoção do papel materno.Palavras-chave: gravidez na adolescência, apoio social, atenção primária í saúde, Enfermagem.

Published: March 2019

Geographically Bangladesh is the treasure-house of medicinal plants especially herbal aphrodisiac medicines. The World Health Organization (WHO) reported that 70%–80% of the global population relies on herbs for primary health care. Sexual health is a state of complete physical, mental and social well-being in all aspects related to the reproductive system. The study aimed as assessing the use of herbal aphrodisiac among Unani & Ayurvedic health care seekers in Dhaka city, knowledge, attitude and practice. The study design was a descriptive cross-sectional study. This study was conducted at Unani and Ayurvedic Medical College Hospital among 220 patients at Mirpur-13, Dhaka using a semi-structured interviewed questionnaire. The study result depicted that 47.7% respondents were in 21-30 years age group. The mean age was 31.22±8.265 years and the range was from 17-50 years. It was found that the prevalence of Premature Ejaculation (PE) and Erectile Dysfunction (ED) was 26.4% and 21.8% respectively. Low level of knowledge was found about different aspects of Unani and Ayurvedic System of Medicine. It was revealed that most of the respondents (95%) knew about the very effective aphrodisiac, their safety and cost issue. It was also revealed that most (79.1%) of the respondents strongly opined about less side-effect of herbal aphrodisiac. The study findings suggest that there is a significant association between age and knowledge about Govt. teaching hospital and between education and knowledge about cost of aphrodisiac in herbal medicine.

The Folk medicinal practitioner (FMP) or Kabiraj plays a key role to provide health support mainly to village people. They are mainly dependent on the pants parts available around them and many modern medicines are being synthesized by extracting the active chemicals from plants. The main objective of this study is to document the plants used by the FMPs of two villages of Jamalpur sadar upazila. For this study, we conducted a survey based on semi structured method. We found they use mainly 31 plants belonging to 25 families. The part mostly used is leave (31.75%) and the least used is the flower (6.34%). It is found that almost 18 types of diseases are being cured by their formulation. This study also suggested that, the FMPs treat many common disorder like gastro intestinal disorder, Respiratory tract infection, diabetes, Skin disorder etc. and also various complicated disorder such as debility, anemia, neural disorder etc. This study may be helpful to create scientific view about the plants used by the FMPs of Jamalpur sadar upazila and these plants might be used to synthesize drug molecule of interest.

Abstract
We report two microlensing events, KMT-2017-BLG-1038 and KMT-2017-BLG-1146, that are caused by planetary systems. These events were discovered by Korea Microlensing Telescope Network survey observations from the 2017 bulge season. The discovered systems consist of a planet and host star with mass ratios of

and

, respectively. Based on a Bayesian analysis assuming a Galactic model without stellar remnant hosts, we find that the planet KMT-2017-BLG-1038Lb is a super-Jupiter-mass planet (

) orbiting a mid-M dwarf host (

) that is located at

kpc toward the Galactic bulge. The other planet, KMT-2017-BLG-1146Lb, is a sub-Jupiter-mass planet (

) orbiting a mid-M dwarf host (

) at a distance of

kpc toward the Galactic bulge. Both are potentially gaseous planets that are beyond their hosts’ snow lines. These typical microlensing planets will be routinely discovered by second-generation microlensing surveys, rapidly increasing the number of detections.
Growth and Settling of Dust Particles in Protoplanetary Nebulae: Implications for Opacity, Thermal Profile, and Gravitational Instability
Authors: Sengupta Debanjan , Dodson-Robinson Sarah E. , Hasegawa Yasuhiro , Turner Neal J. 
Published: March 2019

Abstract
Despite making a small contribution to total protoplanetary disk mass, dust affects the disk temperature by controlling the absorption of starlight. As grains grow from their initial interstellar-medium-like size distribution, settling depletes the disk’s upper layers of dust and decreases the optical depth, cooling the interior. Here we investigate the effect of collisional growth of dust grains and their dynamics on the thermal and optical profile of the disk, and explore the possibility that cooling induced by grain growth and settling could lead to gravitational instability. We develop a Monte Carlo dust collision model with a weighting technique and allow particles to collisionally evolve through sticking and fragmentation, along with vertical settling and turbulent mixing. We explore three disk models and perform simulations for both constant and spatially variable turbulence profile. We then calculate mean wavelength-dependent opacities for the evolving disks and perform radiative transfer to calculate the temperature profile. Finally, we calculate the Toomre Q parameter, a measure of the disk’s stability against self-gravity, after it reaches a steady-state dust-size distribution. We find that even weak turbulence can keep submicrometer-sized particles stirred in the disk’s upper layer, affecting its optical and thermal profiles, and the growth of large particles in the midplane can make a massive disk optically thick at millimeter wavelengths, making it difficult to calculate the surface density of dust available for planet formation in the inner disk. Also, for all our initially marginally stable annuli, we find a small but noticeable reduction in Q.
A High-resolution Mid-infrared Survey of Water Emission from Protoplanetary Disks

Published: March 2019

Abstract
We present the largest survey of spectrally resolved mid-infrared water emission to date, with spectra for 11 disks obtained with the Michelle and TEXES spectrographs on Gemini North. Water emission is detected in six of eight disks around classical T Tauri stars. Water emission is not detected in the transitional disks SR 24 N and SR 24 S, in spite of SR 24 S having pretransitional disk properties like DoAr 44, which does show water emission. With R ∼ 100,000, the TEXES water spectra have the highest spectral resolution possible at this time, and allow for detailed line shape analysis. We find that the mid-IR water emission lines are similar to the “narrow component” in CO rovibrational emission, consistent with disk radii of a few astronomical units. The emission lines are either single peaked, or consistent with a double peak. Single-peaked emission lines cannot be produced with a Keplerian disk model, and may suggest that water participates in the disk winds proposed to explain single-peaked CO emission lines. Double-peaked emission lines can be used to determine the radius at which the line emission luminosity drops off. For HL Tau, the lower limit on this measured dropoff radius is consistent with the 13 au dark ring. We also report variable line/continuum ratios from the disks around DR Tau and RW Aur, which we attribute to continuum changes and line flux changes, respectively. The reduction in RW Aur line flux corresponds with an observed dimming at visible wavelengths.
Spectral Hardening in Black Hole Accretion: Giving Spectral Modelers an f
Authors: Davis Shane W. , El-Abd Samer 
Published: March 2019

Abstract
By fitting synthetic spectral models computed via the TLUSTY code, we examine how the spectra from thin accretion disks are expected to vary in accreting black hole systems. We fit color-corrected blackbody models to our synthetic spectra to estimate the spectral hardening factor f, which parameterizes the departure from blackbody and is commonly used to help interpret multitemperature blackbody fitting results. We find we can define a reasonably robust f value to spectra when the effects of Compton scattering dominate radiation transfer. We examine the evolution of f with black hole mass and accretion rate, typically finding a moderate variation (f ∼ 1.4–2) for accretion rates between 1% and 100% of the Eddington rate. Consistent with most previous work, we find that f tends to increase with accretion rate, but we also infer a weaker correlation of f with black hole mass. We find that f is rarely much larger than 2 unless the disk becomes photon starved, in contention with some previous calculations. Significant spectral hardening (f > 2) is only found when the disk mass surface density is lower than expected for α-disk models unless α is near unity or larger.

Abstract
Planets in close proximity to their parent star, such as those in the habitable zones around M dwarfs, could be subject to particularly high doses of particle radiation. We have carried out test-particle simulations of ∼GeV protons to investigate the propagation of energetic particles accelerated by flares or traveling shock waves within the stellar wind and magnetic field of a TRAPPIST-1-like system. Turbulence was simulated with small-scale magnetostatic perturbations with an isotropic power spectrum. We find that only a few percent of particles injected within half a stellar radius from the stellar surface escape, and that the escaping fraction increases strongly with increasing injection radius. Escaping particles are increasingly deflected and focused by the ambient spiraling magnetic field as the superimposed turbulence amplitude is increased. In our TRAPPIST-1-like simulations, regardless of the angular region of injection, particles are strongly focused onto two caps within the fast wind regions and centered on the equatorial planetary orbital plane. Based on a scaling relation between far-UV emission and energetic protons for solar flares applied to M dwarfs, the innermost putative habitable planet, TRAPPIST-1e, is bombarded by a proton flux up to 6 orders of magnitude larger than experienced by the present-day Earth. We note two mechanisms that could strongly limit EP fluxes from active stars: EPs from flares are contained by the stellar magnetic field; and potential CMEs that might generate EPs at larger distances also fail to escape.
Discovery and Characterization of a Novel HCV Inhibitor Targeting the Late Stage of HCV Life Cycle
Authors: Park Seung Bum , Boyer Audrey , Hu Zongyi , Le Derek , Liang T Jake 
Published: March 2019

Background Currently approved anti-HCV drugs, the direct-acting antivirals (DAAs), are highly effective and target the viral RNA replication stage of the HCV life cycle. Due to high mutation rate of HCV, drug resistant variants can arise during DAA monotherapy. Thus, a combination of DAAs is necessary to achieve a high response rate. Novel HCV inhibitors targeting the HCV late stage such as assembly and release may further improve combination therapy with the DAAs. Here we characterize one late stage-targeting candidate compound, 6-(4-chloro-3-methylphenoxy)-pyridin-3-amine (MLS000833705). Methods: We treated HCV-infected cells with MLS000833705 and other HCV inhibitors and examined HCV RNA and infectious titres. We evaluated the colocalization of HCV core and lipid droplets by confocal microscopy. We performed HCV core-proteinase K digestion assay and several lipid assays to study the mechanism of MLS000833705. Results We showed that MLS000833705 decreased extracellular HCV RNA levels more than intracellular HCV RNA levels in HCV infectious cell culture. Similarly, MLS000833705 reduced infectious HCV titres substantially more in the culture supernatant than intracellularly. Confocal microscopy showed that MLS000833705 did not affect the colocalization of HCV core protein with cellular lipid droplets where HCV assembles. HCV core-proteinase K digestion assay showed that MLS000833705 inhibited the envelopment of HCV capsid. Conclusions Our study demonstrates that MLS000833705 is a late-stage HCV inhibitor targeting HCV morphogenesis and maturation. Therefore, MLS000833705 can be used as a molecular probe to study HCV maturation and secretion and possibly guide development of a new class of HCV antivirals.
Survey of the reproductive development of field-caught Halyomorpha halys (Hemiptera: Pentatomidae) in the Niagara Region of Ontario, Canada

Published: March 2019

AbstractHalyomorpha halys (Stål) (Hemiptera: Pentatomidae), also known as the brown marmorated stink bug, is an invasive agricultural and nuisance pest. Knowledge of the life history of insect pests is important for informing pest management activities. Some North American populations of H. halys have two generations per year, and it is suspected that H. halys may have a partial second generation in the Niagara Region of Ontario, Canada. We determined the number of H. halys generations in Ontario by examining the reproductive development of field-caught adult females. The pattern of reproductive development we observed supports the conclusion that H. halys complete one generation per year in the Niagara Region of Ontario. Reproductively active H. halys were captured as early as May and continued until early September, and the peak of reproductively active individuals occurred between 250 and 550 degree days calculated with a sine-wave function and a lower threshold set to 14.17 °C.
