Authors: Tran Thai Son , Thai Khac Minh , Tran Thanh Dao
Published: March 2020

Background: Alzheimer is a major cause of dementia in the elderly and acetylcholinesterase inhibitors are used to treat the symptoms of this disease. Recently, chalcones have been reported as potential acetylcholinesterase inhibitors. Materials and methods: In this study, Claisen-Schmidt condensation reaction was applied to synthesize chalcones. Anti-acetylcholinesterase activity of these chalcones was determined by Ellman method. Molecular docking studies on acetylcholinesterase were performed to explain the interaction between these chalcone analogues and acetylcholinesterase active site at molecular level. Results: A total of twenty chalcones were synthesized and determined for in vitro anti-acetylcholinesterase activity. The results indicated that six compounds having IC50 value below 100 µM, three compounds having IC50 value in the range of 100 µM and 300 µM, the rest having IC50 value above 300 µM. Chalcone S17 (4’-amino-2-chlorochalcone) shows the strongest anti-acetylcholinesterase activity in the investigated group with IC50 value of 36.10 µM. In combination with the results of the in vitro anti-acetylcholinesterase activity, molecular docking study is used to explain the interaction between chalcone molecules and their active site, and the structure-activity relationship is abstracted. Conclusions: Our study indicated that the 2’-hydroxychalcones with halogen functional groups on B ring are strong acetylcholinesterase inhibitors. Chalcone S17 (4’-amino-2-chlorochalcone) could be considered as a potential lead compound for the development of new acetylcholinesterase inhibitors.

Organization and Challenges of the Human Resources Function in a Cruise Ship Company
Authors: Suárez Esperanza , Susaeta Lourdes , Babinger Frank
Published: March 2020

Since the Maritime Labor Convention (MLC) came into force, cruise line companies have been required to make human resource (HR) organizational changes in order to comply with the corresponding rules on employees' rights. This article offers an overview of the role and organization of
HR in the Spanish cruise line company Pullmantur. This research suggests that cruise HR managers face greater challenges, compared to those of other sectors, not only because of the specific regulations affecting cruise line companies, but also because of the complexity of the processes from
recruitment to incorporation. Pullmantur's case illustrates a particular way of organizing the HR planning and assignment of its personnel, reflected in their Crew Cycle Life (CCL). After having reviewed different documents as well as interviews carried out with Pullmantur's HR management,
this article describes and examines the different positions, functions, and responsibilities of HR "on ship and shore." It concludes that HR's function within a cruise ship company is more stressful and complex, but at the same time, more vibrant and challenging than in other industries.

Este artículo analiza el funcionamiento de los juzgados protectorios del Departamento Judicial La Plata provincia de Buenos Aires, Argentina. Su enfoque trasciende el análisis procesalista porque incluye los testimonios de las justiciables. Reflexiona sobre la administración de la justicia de familia y los nuevos diseños de políticas públicas que atienden la problemática de la violencia contra las mujeres, desde una perspectiva de género. Las observaciones están centradas en algunas de las etapas en que se despliega el acceso a la justicia de las mujeres: creación normativa, interpretación jurídica, ejecución de la resolución judicial por el órgano estatal competente. Destacando en este proceso la agencia de las mujeres organizadas y de los sectores sociales sensibles a esta problemática que con su accionar actúan sobre la producción legislativa instalando temas en la agenda política, denunciando aquellas prácticas que se desvían del sentido que les dio origen y monitoreando las políticas públicas que las contienen.
Es decir, este trabajo focaliza las funciones del derecho en un contexto social determinado, considerando que no sólo es un sistema normativo, sino también un discurso social y un proceso que construye y reproduce significaciones sociales a través de actores sociales legitimados que forman opinión como por ejemplo los y las legisladoras, los/as doctrinarios/as y los medios de comunicación.

Indonesia merupakan salah satu negara berkembang yang masih terus berusaha untuk meningkatkan kualitas pendidikan di dalam negaranya. Kualitas pendidikan di Indonesia menjadi salah satu hal yang patut untuk mendapatkan perhatian lebih dari pemerintah dan seluruh elemen masyarakat Indonesia. Hal ini tidak lain disebabkan karena kualitas pendidikan di Indonesia turut mempengaruhi kemajuan bangsa Indonesia itu sendiri. Salah satu faktor pendukung yang dapat mempengaruhi daya saing masyarakat Indonesia adalah kualitas pendidikan di Indonesia. Dengan kata lain, kualitas pendidikan di Indonesia akan menjadi cerminan dari kualitas sumber daya manusia yang dimiliki oleh negara Indonesia. Namun, kita tidak dapat memungkiri jika kualitas pendidikan di Indonesia masih jauh di bawah rata-rata kualitas pendidikan di negara-negara berkembang lainnya. Perbaikan pada manajemen pendidikan di sekolah dirasa mampu untuk membantu mengatasi permasalahan mutu pendidikan di Indonesia. Dengan adanya manajemen pendidikan maka akan ada suatu sistem yang mampu melibatkan berbagai aspek dalam pendidikan itu sendiri sehingga mampu mencapai tujuan dengan efektif dan efisien. Bidang-bidang garapan manajemen sekolah harus saling berkaitan dalam menjalankan tugasnya agar manajemen pendidikan di sekolah bisa terlaksana dengan baik. Dalam menjalankan tugas pokok dan fungsi dari bidangbidang garap manajemen sekolah tersebut, tentunya ada tantangan manajemen sekolah yang harus dihadapi para penyelenggara pendidikan.

ABSTRACT

This study aims to analyze the human development index that is multidimensional and complex which includes economic, governance and demographic aspects represented by 13 independent variables in 10 countries of Southeast Asia. However, these efforts are often constrained by incomplete data and data reliability. Unlike some previous studies which focused more on the variables forming the human development index, such as life expectancy, literacy rates and the average number of years of education or independent variables of economic aspects. This research includes aspects of governance and population aspects that are expected to complement the spectrum and study of aspects of human development. The method used in this study uses pooled least squares. In research that uses a 95% confidence level, it was found that from 13 variables there are only five variables that significantly influence increasing human development index.

Gravity-dominated Collisions: A Model for the Largest Remnant Masses with Treatment for “Hit and Run” and Density Stratification
Authors: Gabriel Travis S. J. , Jackson Alan P. , Asphaug Erik , Reufer Andreas , Jutzi Martin , Benz Willy
Published: March 2020

We develop empirical relationships for the accretion and erosion of colliding gravity-dominated bodies of various compositions under conditions expected in late-stage solar system formation. These are fast, easily coded relationships based on a large database of smoothed particle hydrodynamics (SPH) simulations of collisions between bodies of different compositions, including those that are water rich. The accuracy of these relations is also comparable to the deviations of results between different SPH codes and initial thermal/rotational conditions. We illustrate the paucity of disruptive collisions between major bodies, as compared to collisions between less massive planetesimals in late-stage planet formation, and thus focus on more probable, low-velocity collisions, though our relations remain relevant to disruptive collisions as well. We also pay particular attention to the transition zone between merging collisions and those where the impactor does not merge with the target, but continues downrange, a “hit-and-run” collision. We find that hit-and-run collisions likely occur more often in density-stratified bodies and across a wider range of impact angles than suggested by the most commonly used analytic approximation. We also identify a possible transitional zone in gravity-dominated collisions where larger bodies may undergo more disruptive collisions when the impact velocity exceeds the sound speed, though understanding this transition warrants further study. Our results are contrary to the commonly assumed invariance of total mass (scale), density structure, and material composition on the largest remnants of giant impacts. We provide an algorithm for adopting our model into N-body planet formation simulations, so that the mass of growing planets and debris can be tracked.

Published: March 2020

We report measurements with the Very Long Baseline Array of the proper motion of Sgr A* relative to two extragalactic radio sources spanning 18 yr. The apparent motion of Sgr A* is −6.411 ± 0.008 mas yr−1 along the Galactic plane and −0.219 ± 0.007 mas yr−1 toward the North Galactic Pole. This apparent motion can almost entirely be attributed to the effects of the Sun’s orbit about the Galactic center. Removing these effects yields residuals of −0.58 ± 2.23 km s−1 in the direction of Galactic rotation and −0.85 ± 0.75 km s−1 toward the North Galactic Pole. A maximum-likelihood analysis of the motion, both in the Galactic plane and perpendicular to it, expected for a massive object within the Galactic center stellar cluster indicates that the radiative source, Sgr A*, contains more than about 25% of the gravitational mass of 4 × 106

deduced from stellar orbits. The intrinsic size of Sgr A* is comparable to its Schwarzschild radius, and the implied mass density of

pc−3 is very close to that expected for a black hole, providing overwhelming evidence that it is indeed a supermassive black hole. Finally, “intermediate mass” black holes more massive than ≈3 × 104

between approximately 0.003 and 0.1 pc from Sgr A*  are excluded.
Properties of Trans-fast Magnetosonic Jets in Black Hole Magnetospheres
Authors: Pu Hung-Yi , Takahashi Masaaki
Published: March 2020

Traveling across several orders of magnitude in distance, relativistic jets from strong gravity regions to asymptotic flat spacetime regions are believed to consist of several general relativistic magnetohydrodynamic (GRMHD) processes. We present a semianalytical approach for modeling the global structures of a trans-fast magnetosonic relativistic jet, which should be ejected from a plasma source near a black hole in a funnel region enclosed by dense accreting flow and a disk corona around the black hole. Our model consistently includes the inflow and outflow part of the GRMHD solution along the magnetic field lines penetrating the black hole horizon. After the rotational energy of the black hole is extracted electromagnetically by the negative energy GRMHD inflow, the huge electromagnetic energy flux propagates from the inflow to the outflow region across the plasma source, and in the outflow region, the electromagnetic energy converts to the fluid kinetic energy. Eventually, the accelerated outflow must exceed the fast magnetosonic wave speed. We apply the semianalytical trans-fast magnetosonic flow model to the black hole magnetosphere for both parabolic and split-monopole magnetic field configurations and discuss the general flow properties, that is, jet acceleration, jet magnetization, and the locations of some characteristic surfaces of the black hole magnetosphere. We have confirmed that, at large distances, the GRMHD jet solutions are in good agreement with the previously known trans-fast special relativistic magnetohydrodynamic jet properties, as expected. The flexibility of the model provides a prompt and heuristic way to approximate the global GRMHD trans-fast magnetosonic jet properties.
Making a Supermassive Star by Stellar Bombardment

Published: March 2020

Approximately 200 supermassive black holes (SMBHs) have been discovered within the first ∼gigayear after the Big Bang. One pathway for the formation of SMBHs is through the collapse of supermassive stars (SMSs). A possible obstacle to this scenario is that the collapsing gas fragments and forms a cluster of main-sequence stars. Here, we raise the possibility that stellar collisions may be sufficiently frequent and energetic to inhibit the contraction of the massive protostar, avoiding strong UV radiation driven outflows, and allowing it to continue growing into an SMS. We investigate this scenario with semianalytic models incorporating star formation; gas accretion; dynamical friction from stars and gas; stellar collisions; and gas ejection. We find that when the collapsing gas fragments at a density of ≲3 × 1010 cm−3, the central protostar contracts due to infrequent stellar mergers, and in turn photoevaporates the remaining collapsing gas, resulting in the formation of a ≲104
M
⊙ object. On the other hand, when the collapsing gas fragments at higher densities (expected for a metal-poor cloud with Z ≲ 10−5
Z
⊙ with suppressed H2 abundance) the central protostar avoids contraction and keeps growing via frequent stellar mergers, reaching masses as high as ∼105–106
M
⊙. We conclude that frequent stellar mergers represent a possible pathway to form massive BHs in the early universe.
A Toy Model for the Electromagnetic Output of Neutron-star Merger Prompt Collapse to a Black Hole: Magnetized Neutron-star Collisions
Authors: Nathanail Antonios
Published: March 2020

We present a systematic study of magnetized neutron star head-on collisions. We investigate the resulting magnetic field geometries as the two neutron stars merge. Furthermore, we analyze the luminosity produced in these collisions and monitor the evolution of the magnetic fields from the time of merger until the subsequent production of a black hole. At the time of black hole formation, the luminosity peaks and rings down following the decay of the electromagnetic fields. A comparison is presented for three different cases: one where the initial magnetic field in both neutron stars is aligned, one where they are anti-aligned, and one where they initially have unequal magnetic field strength. We identify regions and set limits so that pair creation and magnetic reconnection would occur in this scenario and further discuss limits and differences in the radiated energy. This study should be regarded as a toy model of the case where the remnant of a binary neutron star merger undergoes a prompt collapse to a black hole with a negligible surrounding disk. We note that the generated electromagnetic pulses resemble the fast radio burst phenomenology. We consider implications of the high-mass mergers leading to a fast prompt collapse to a black hole and the expected flux to be observed at a distance similar to the binary neutron star gravitational wave detection GW190425.

Published: March 2020

We present the analysis of deep optical imaging of the galaxy cluster A133 with the IMACS instrument on Magellan. Our multi-band photometry enables stellar-mass measurements in the cluster member galaxies down to a mass limit of

(≈0.1 of the Large Magellanic Cloud stellar mass). We observe a clear difference in the spatial distribution of large and dwarf galaxies within the cluster. Modeling these galaxy populations separately, we can confidently track the distribution of stellar mass locked in the galaxies to the cluster’s virial radius. The extended envelope of the cluster’s brightest galaxy can be tracked to ∼200 kpc. The central galaxy contributes ∼1/3 of the total cluster stellar mass within the radius

Two new species of socially parasitic Nylanderia ants from the southeastern United States
Authors: Messer Steven J. , Cover Stefan P. , Rabeling Christian
Published: March 2020

In ants, social parasitism is an umbrella term describing a variety of life-history strategies, where a parasitic species depends entirely on a free-living species, for part of or its entire life-cycle, for either colony founding, survival, and/or reproduction. The highly specialized inquiline social parasites are fully dependent on their hosts for their entire lifecycles. Most inquiline species are tolerant of the host queen in the parasitized colony, forgo producing a worker caste, and invest solely in the production of sexual offspring. In general, inquilines are rare, and their geographic distribution is limited, making it difficult to study them. Inquiline populations appear to be small, cryptic, and they are perhaps ephemeral. Thus, information about their natural history is often fragmentary or non-existent but is necessary for understanding the socially parasitic life history syndrome in more detail. Here, we describe two new species of inquiline social parasites, Nylanderia deyrupisp. nov. and Nylanderia parasiticasp. nov., from the southeastern United States, parasitizing Nylanderia wojciki and Nylanderia faisonensis, respectively. The formicine genus Nylanderia is large and globally distributed, but until the recent description of Nylanderia deceptrix, social parasites were unknown from this genus. In addition to describing the new social parasite species, we summarize the fragmentary information known about their biology, present a key to both the queens and the males of the Nylanderia social parasites, and discuss the morphology of the social parasites in the context of the inquiline syndrome.

Le bouleversement de la régulation du travail, par le recours à une main-d’œuvre sans lien d’emploi direct avec l’entreprise, se trouve au cœur du modèle d’affaires du capitalisme de plateforme. Partout, la nature de la relation entre les plateformes de VTC et les chauffeurs est contestée et se trouve au cœur des conflits juridiques et administratifs. Partout, le pouvoir judicaire joue un rôle clé dans la qualification de la nature de la prestation du service comme celle du « prestataire du service », à savoir, le chauffeur.
Maximum and minimum ranks and inertias of the Hermitian parts of the least rank solution of the matrix equation AXB = C
Authors: Guerarra Sihem

In this paper we derive the extremal ranks and inertias of the matrix \begin{document}$ X+X^{\ast}-P $\end{document}, with respect to \begin{document}$ X $\end{document}, where \begin{document}$ P\in\mathbb{C} _{H}^{n\times n} $\end{document} is given, \begin{document}$ X $\end{document} is a least rank solution to the matrix equation \begin{document}$ AXB = C $\end{document}, and then give necessary and sufficient conditions for \begin{document}$ X+X^{\ast}\succ P $\end{document} \begin{document}$ \left( \geq P\text{, }\prec P\text{, }\leq P\right) $\end{document} in the Löwner partial ordering. As consequence, we establish necessary and sufficient conditions for the matrix equation \begin{document}$ AXB = C $\end{document} to have a Hermitian Re-positive or Re-negative definite solution.
Effectiveness of a Leadership Development Course for Chief Residents: A Longitudinal Evaluation
Authors: Mustafa Sultana , Stoller James K. , Bierer S. Beth , Farver Carol F.
Published: March 2020

Background

Nonclinical skills (eg, self-regulation, team leadership, conflict resolution) are essential for success as a chief resident (CR). The literature on programs teaching these skills reports few if any effectiveness outcomes.

Objective

We reported the outcomes of a leadership course for CRs using participants' self-reported outcomes and assessments from their program directors (PDs).

Methods

A 2-day curriculum focused on emotional intelligence competencies, including self-awareness, self-management, social awareness, and relationship management. We used a logic model to align 2017–2018 curriculum with targeted outcomes. Questionnaires before and after the course assessed short-term and intermediate outcomes for the participants and PD interviews evaluated observed changes in CRs' performance attributable to the course.

Results

A total of 74 residents participated in the course, and 65% and 59% responded to the post-course and follow-up questionnaires, respectively. Over 95% of respondents indicated developing leadership knowledge and skills and connecting with new CRs in the post-course questionnaire. During follow-up, CRs reported applying concepts learned during chief residency, using tools to address conflict, engaging in quality and patient safety projects, and continuing to interact with other participants. The relationships between reported outcomes and participants' gender/prior leadership training were not significant (P > .05), with small to medium effect sizes (0.01–0.32). All 14 PDs offered positive appraisal of the CRs, but we could not specifically attribute this growth to the course.

Conclusions

Participation in this CR leadership development course was associated with enhancement and application of leadership competencies in immediate and intermediate time frames.
