SURAU SEBAGAI PUSAT PENDIDIKAN ISLAM PADA MASA KESULTANAN PONTIANAK
Authors: Rahmatullah Muhammad 
Published: March 2017

Historically, the surau has become an important means (institution/agency) in terms of community development and enlightenment, particularly in religious learning and cultivation of moral values. In addition, the surau-based education had a significant reputation with regard to the spread of Islam to various regions and the area around an island and beyond, and probably to other countries.
As a means of religious education, we can still find surau until now, although its role and function are no longer the same as they were in the past, in which educational activities of Islam in the early days of its growth were carried out under the surau educational system. Thus, since the beginning of the spread of Islam to Indonesia, surau has contributed the shape and pattern of its own in the Islamic educational system
PERILAKU MUNAFIK INDIKATOR GANGGUAN JIWA
Authors: Handini Agust 
Published: March 2017

Orang-orang munafik pada dasarnya adalah mereka yang ingkar kepada Allah, dan Rasul-Nya, kendatipun secara lahir mereka memakai baju mukmin. Abu Bakar Jabir Al-Jaziri berpendapat bahwa orang-orang munafik itu adalah mereka yang menampakkan keimanan terhadap orang-orang mukmin dengan ucapan-ucapan mereka, akan tetapi menyembunyikan kekafiran dalam hati mereka dan juga mengingkari syara’ serta kufur untuk kepentingan mereka kepada Allah dan Rasul-Nya.
Dalam pandangan Murtadha Muthahari, kemunafikkan dimaknai sebagai sikap bermuka dua dan menampakkan diri secara berbeda dari keadaan yang seseungguhnya. Kendati merupakan sifat yang licik, kemunafikkan menunjukkan evolusi manusia. Artinya manakala manusia jauh lebuh berkembang daripada binatang biasanya tidak memiliki sifat seperti itu.
Tanda orang munafik ada tiga :
•	Apabila ia berbicara berdusta,
•	Apabila ia berjani ia ingkar, dan
Apabila dia dipercayai ia berkhianat. Ciri yang paling mendasar adalah kebimbangannya antara keimanan dan kekafiran serta ketakmampuannya membuat sikap yang tegas dan jelas berkaitan dengan keyakinan tauhid. Hal itu karena ia adalah pribadi yang kurang percaya diri. Mereka tidak dapat membuat keputusan yang tegas dan jelas untuk bergabung dengan kaum mukminin atau dengan kaum musyrikin.
INTERPRETASI SEJARAH SEBAGAI PERISTIWA DAN MASALAH PENDIDIKAN
Authors: Maksum Ahmad 
Published: March 2017

When we talk about history, we usually think of the past and interpret it as something insignificant that does not need to be remembered at all. People merely know the events on the surface, but are not aware of the background. For historians and observers of history, an event must be explained further and more in-depth especially about how it happened, as well as social, economic, political, and cultural backgrounds. Simply recounting an event does not completely explain it, because historians are professional travelers in the world of the past. In the academic context, history is a field of science or study that requires a critical historical imagination in its analysis. This is intended to place history in its phenomenological setting. History is not only about the “past events”, but it is also related to current events. The role of historians is very strategic especially in changing society’s idea which should start from the concept of learning at school or college.
In this light, historians and history teachers should be able to see through the mind of historical actors by trying to revive the thoughts of the historical actors in his/her own mind; in other words, historians should be able to put themselves into the shoes of the actors in history. It is considered an essential element in the “historical thinking” which serves as the basis of historical explanation.
History as an autonomous discipline needs to be developed in accordance with the pattern of the tendency of history itself. Conventional historical writing only tells the story of history in a descriptive-narrative form, simply explaining how an event occurs and does not touch its focal point. To get a more complete picture of the reality, people need to approach historical events from various aspects better known as a multidimensional approach, and it certainly requires a method called an interdisciplinary method.

A Differential Abundance Analysis of Very Metal-poor Stars*

†
Authors: O’Malley Erin M. , McWilliam Andrew , Chaboyer Brian , Thompson Ian 
Published: March 2017

Abstract
We have performed a differential line-by-line chemical abundance analysis, ultimately relative to the Sun, of nine very metal-poor main-sequence (MS) halo stars, near [Fe/H] = −2 dex. Our abundances range from

dex with conservative uncertainties of 0.07 dex. We find an average [α/Fe] = 0.34 ± 0.09 dex, typical of the Milky Way. While our spectroscopic atmosphere parameters provide good agreement with Hubble Space Telescope parallaxes, there is significant disagreement with temperature and gravity parameters indicated by observed colors and theoretical isochrones. Although a systematic underestimate of the stellar temperature by a few hundred degrees could explain this difference, it is not supported by current effective temperature studies and would create large uncertainties in the abundance determinations. Both 1D and

hydrodynamical models combined with separate 1D non-LTE effects do not yet account for the atmospheres of real metal-poor MS stars, but a fully 3D non-LTE treatment may be able to explain the ionization imbalance found in this work.

Abstract
In this paper we present an analysis of absorption-line variability in mini-BAL quasar LBQS 1206+1052. The Sloan Digital Sky Survey spectrum demonstrates that the absorption troughs can be divided into two components of blueshift velocities of ∼700 and ∼1400 km s−1 relative to the quasar rest frame. The former component shows rare Balmer absorption, which is an indicator of high-density absorbing gas; thus, the quasar is worth follow-up spectroscopic observations. Our follow-up optical and near-infrared spectra using MMT, YFOSC, TSpec, and DBSP reveal that the strengths of the absorption lines vary for both components, while the velocities do not change. We reproduce all of the spectral data by assuming that only the ionization state of the absorbing gas is variable and that all other physical properties are invariable. The variation of ionization is consistent with the variation of optical continuum from the V-band light curve. Additionally, we cannot interpret the data by assuming that the variability is due to a movement of the absorbing gas. Therefore, our analysis strongly indicates that the absorption-line variability in LBQS 1206+1052 is photoionization driven. As shown from photoionization simulations, the absorbing gas with blueshift velocity of ∼700 km s−1 has a density in the range of 109 to 1010 cm−3 and a distance of ∼1 pc, and the gas with blueshift velocity of ∼1400 km s−1 has a density of 103 cm−3 and a distance of ∼1 kpc.
PRIMUS+DEEP2: The Dependence of Galaxy Clustering on Stellar Mass and Specific Star Formation Rate at 0.2 < z < 1.2
Authors: Coil Alison L. , Mendez Alexander J. , Eisenstein Daniel J. , Moustakas John 
Published: March 2017

Abstract
We present results on the clustering properties of galaxies as a function of both stellar mass and specific star formation rate (sSFR) using data from the PRIMUS and DEEP2 galaxy redshift surveys spanning

. We use spectroscopic redshifts of over 100,000 galaxies covering an area of 7.2 deg2 over five separate fields on the sky, from which we calculate cosmic variance errors. We find that the galaxy clustering amplitude is as strong of a function of sSFR as of stellar mass, and that at a given sSFR, it does not significantly depend on stellar mass within the range probed here. We further find that within the star-forming population and at a given stellar mass, galaxies above the main sequence of star formation with higher sSFR are less clustered than galaxies below the main sequence with lower sSFR. We also find that within the quiescent population, galaxies with higher sSFR are less clustered than galaxies with lower sSFR, at a given stellar mass. We show that the galaxy clustering amplitude smoothly increases with both increasing stellar mass and decreasing sSFR, implying that galaxies likely evolve across the main sequence, not only along it, before galaxies eventually become quiescent. These results imply that the relation of stellar mass to halo mass, which connects galaxies to dark matter halos, likely depends on sSFR.
Triangulum II. Not Especially Dense After All*
Authors: Kirby Evan N. , Cohen Judith G. , Simon Joshua D. , Guhathakurta Puragra , Thygesen Anders O. , Duggan Gina E. 
Published: March 2017

Abstract
Among the Milky Way satellites discovered in the past three years, Triangulum II has presented the most difficulty in revealing its dynamical status. Kirby et al. identified it as the most dark-matter-dominated galaxy known, with a mass-to-light ratio within the half-light radius of

. On the other hand, Martin et al. measured an outer velocity dispersion that is 3.5 ± 2.1 times larger than the central velocity dispersion, suggesting that the system might not be in equilibrium. From new multi-epoch Keck/DEIMOS measurements of 13 member stars in Triangulum II, we constrain the velocity dispersion to be

km s−1 (90% C.L.). Our previous measurement of

, based on six stars, was inflated by the presence of a binary star with variable radial velocity. We find no evidence that the velocity dispersion increases with radius. The stars display a wide range of metallicities, indicating that Triangulum II retained supernova ejecta and therefore possesses, or once possessed, a massive dark matter halo. However, the detection of a metallicity dispersion hinges on the membership of the two most metal-rich stars. The stellar mass is lower than galaxies of similar mean stellar metallicity, which might indicate that Triangulum II is either a star cluster or a tidally stripped dwarf galaxy. Detailed abundances of one star show heavily depressed neutron-capture abundances, similar to stars in most other ultra-faint dwarf galaxies but unlike stars in globular clusters.
Tracing the Cosmological Evolution of Stars and Cold Gas with CMB Spectral Surveys
Authors: Switzer Eric R. 
Published: March 2017

Abstract
A full account of galaxy evolution in the context of ΛCDM cosmology requires measurements of the average star-formation rate (SFR) and cold gas abundance across cosmic time. Emission from the CO ladder traces cold gas, and [C ii] fine structure emission at

traces the SFR. Intensity mapping surveys the cumulative surface brightness of emitting lines as a function of redshift, rather than individual galaxies. CMB spectral distortion instruments are sensitive to both the mean and anisotropy of the intensity of redshifted CO and [C ii] emission. Large-scale anisotropy is proportional to the product of the mean surface brightness and the line luminosity-weighted bias. The bias provides a connection between galaxy evolution and its cosmological context, and is a unique asset of intensity mapping. Cross-correlation with galaxy redshift surveys allows unambiguous measurements of redshifted line brightness despite residual continuum contamination and interlopers. Measurement of line brightness through cross-correlation also evades cosmic variance and suggests new observation strategies. Galactic foreground emission is

times larger than the expected signals, and this places stringent requirements on instrument calibration and stability. Under a range of assumptions, a linear combination of bands cleans continuum contamination sufficiently that residuals produce a modest penalty over the instrumental noise. For PIXIE, the

sensitivity to CO and [C ii] emission scales from

at low redshift to

by reionization.
A Curved Magnetic Field in the Ring-like Shell of Bubble N4

Published: March 2017

Abstract
We report the detection of a curved magnetic field in the ring-like shell of the bubble N4, derived from near-infrared polarization of reddened diskless stars located behind this bubble. The magnetic field in the shell is curved and parallel to the ring-like shell, and its strength is estimated to be

in the plane of the sky. The magnetic field strength in the shell is significantly enhanced compared to the local field strength. We calculate the mass-to-flux ratio for the submillimeter clumps in the shell and find that they are all magnetically subcritical. Our results demonstrate that the magnetic field strengthens as the interstellar medium is compressed into a shell, and suggest that the magnetic field has the potential to hinder star formation triggered by H ii region expansion.
Linear Polarization, Circular Polarization, and Depolarization of Gamma-ray Bursts: A Simple Case of Jitter Radiation
Authors: Mao Jirong , Wang Jiancheng 
Published: March 2017

Abstract
Linear and circular polarizations of gamma-ray bursts (GRBs) have been detected recently. We adopt a simplified model to investigate GRB polarization characteristics in this paper. A compressed two-dimensional turbulent slab containing stochastic magnetic fields is considered, and jitter radiation can produce the linear polarization under this special magnetic field topology. Turbulent Faraday rotation measure (RM) of this slab makes strong wavelength-dependent depolarization. The jitter photons can also scatter with those magnetic clumps inside the turbulent slab, and a nonzero variance of the Stokes parameter V can be generated. Furthermore, the linearly and circularly polarized photons in the optical and radio bands may suffer heavy absorptions from the slab. Thus we consider the polarized jitter radiation transfer processes. Finally, we compare our model results with the optical detections of GRB 091018, GRB 121024A, and GRB 131030A. We suggest simultaneous observations of GRB multi-wavelength polarization in the future.

Abstract
We perform Jeans anisotropic modeling (JAM) on elliptical and spiral galaxies from the MaNGA DR13 sample. By comparing the stellar mass-to-light ratios estimated from stellar population synthesis and from JAM, we find a systematic variation of the initial mass function (IMF) similar to that in the earlier

results. Early-type galaxies (elliptical and lenticular) with lower velocity dispersions within one effective radius are consistent with a Chabrier-like IMF, while galaxies with higher velocity dispersions are consistent with a more bottom-heavy IMF such as the Salpeter IMF. Spiral galaxies have similar systematic IMF variations, but with slightly different slopes and larger scatters, due to the uncertainties caused by the higher gas fractions and extinctions for these galaxies. Furthermore, we examine the effects of stellar mass-to-light ratio gradients on our JAM modeling, and we find that the trends become stronger after considering the gradients.

Published: March 2017

The purpose of this paper is to investigate the impact of human memory in language comprehension and specifically to examine the relationship between the function of working memory and the fields of linguistic analysis which are phonology, morphology, syntax, semantics and pragmatics. Working memory -as one of the most important cognitive skills of human brain- comprises a system with specific functions with which the information from the external environment are being transferred, encoded, stored and retrieved. The present study is an attempt to explore which specific function of working memory is activated in order to decode each linguistic field of analysis. Furthermore, it features the current scientific achievements on the ICTs processes and tools, which exploit the cognitive skill of memory and they are applied in the assessment of difficulties in text comprehension, intervention and training of the language comprehension ability.
Implementation of a single sign-on system between practice, research and learning systems
Authors: Purkayastha Saptarshi , Gichoya Judy W. , Addepally Abhishek Siva 
Published: March 2017

SummaryBackground: Multiple specialized electronic medical systems are utilized in the health enterprise. Each of these systems has their own user management, authentication and authorization process, which makes it a complex web for navigation and use without a coherent process workflow. Users often have to remember multiple passwords, login/logout between systems that disrupt their clinical workflow. Challenges exist in managing permissions for various cadres of health care providers. Objectives: This case report describes our experience of implementing a single sign-on system, used between an electronic medical records system and a learning management system at a large academic institution with an informatics department responsible for student education and a medical school affiliated with a hospital system caring for patients and conducting research.Methods: At our institution, we use OpenMRS for research registry tracking of interventional radiology patients as well as to provide access to medical records to students studying health informatics. To provide authentication across different users of the system with different permissions, we developed a Central Authentication Service (CAS) module for OpenMRS, released under the Mozilla Public License and deployed it for single sign-on across the academic enterprise. The module has been in implementation since August 2015 to present, and we assessed usability of the registry and education system before and after implementation of the CAS module. 54 students and 3 researchers were interviewed.Results: The module authenticates users with appropriate privileges in the medical records system, providing secure access with minimal disruption to their workflow. No passwords requests were sent and users reported ease of use, with streamlined workflow.Conclusions: The project demonstrates that enterprise-wide single sign-on systems should be used in healthcare to reduce complexity like “password hell”, improve usability and user navigation. We plan to extend this to work with other systems used in the health care enterprise.
On the mesoscale monitoring capability of Argo floats in the Mediterranean Sea
Authors: Sánchez-Román Antonio , Ruiz Simón , Pascual Ananda , Mourre Baptiste , Guinehut Stéphanie 
Published: March 2017

Abstract. In this work a simplified observing system simulation experiment (OSSE) approach is used to investigate which Argo design sampling in the Mediterranean Sea would be necessary to properly capture the mesoscale dynamics in this basin. The monitoring of the mesoscale features is not an initial objective of the Argo network. However, it is an interesting question from the perspective of future network extensions in order to improve the ocean state estimates. The true field used to conduct the OSSEs is provided by a specific altimetry-gridded merged product for the Mediterranean Sea. Synthetic observations were obtained by sub-sampling this Nature Run according to different configurations of the ARGO network. The observation errors required to perform the OSSEs were obtained through the comparison of sea level anomalies (SLAs) from altimetry and dynamic height anomalies (DHAs) computed from the real in situ Argo network. This analysis also contributes to validate satellite SLAs with an increased confidence. The simulation experiments show that a configuration similar to the current Argo array in the Mediterranean (with a spatial resolution of 2°  ×  2°) is only able to recover the large-scale signals of the basin. Increasing the spatial resolution to nearly 75 km  ×  75 km, allows the capture of most of the mesoscale signal in the basin and to retrieve the SLA field with a RMSE of 3 cm for spatial scales larger than 150 km, similar to those presently captured by the altimetry. This would represent a theoretical reduction of 40 % of the actual RMSE. Such a high-resolution Argo array composed of around 450 floats, cycling every 10 days, is expected to increase the actual network cost by approximately a factor of 6.
