Normalized Chaos: Black Feminism, Womanism, and the (Re)definition of Trauma and Healing
Authors: Ricks Shawn Arango 
Published: May 2018

Abstract
This paper will discuss how the lens through which Black women view narratives of trauma and resiliency problematizes healing. Lessons learned via elders on how to view and situate themselves within the world can lead to living in a state of “normalized chaos.” Normalized chaos is defined as a defense mechanism used by Black women to minimize daily hassels and life situations, viewing them as part of their “normal” life. Normalizing chaos leads to cocreated self-violence and trauma under the guise of martyrdom. By disrupting the narrative of normalized chaos within an expanded understanding of Black feminism and womanism, Black women can more fully engage in holistic health journeys.
Nilai Waktu Dari Uang Dalam Perspektif Ekonomi Islam
Authors: Khoir Misbahul 
Published: May 2018

The time value of money is associated with the current value and future value because the money received now is more worth than the money received in the future. However, is the concept of time value of money is appropriate and justified by the Shari'ah? The time value of money is a concept that says that the money of the one rupiah that can be received today is more worth than one rupiah which will be received in the future time. The concept of time value of money is needed by financial managers in making decision when will invest in an asset and determine the source of loan funds that will be chosen. Methods for the time value of money pervade; a) the method of average rate of return. This method measures the level of profit gained by an investment. The disadvantage of this method is ignoring the time value of money; b) the payback period method. The method measures how fast the investment return is, the sooner the better; c) method of net present value (NPV). This method calculates quarrel between the current value of investment and the present value of net cash receipts in the future and calculates quarrel between the present value of cash outflow (investment) and cash inflow (income) per year; d) profitability index method (PI). This method calculates ratio between the present value of net cash receipts in the future and the present value of the investment; and e) the methods of internal rate of return (IRR). If IRR > saving or profit required → decent. Islam views money as a flow concept. Money must rotate in an economy and may not be idle for too long time. Moreover, it lets for years. Islam does not recognize the method of time value of money because this method adds value to money solely with increasing time and not effort. Islam actually knows the money value of time; that is the time has economic value as well as the money value of money. Imam Nawawi provides definition related to value addition for money based solely on the value of time is the category of riba.

Published: May 2018

ABSTRACT
Background: Preconditioning and prehabilitation have been reported to ameliorate a host of health- and cancer-related issues, yet few studies have examined implications of past physical activity (PA) on physiological and psychological parameters in cancer survivors. Implications of prior PA on physiological and psychosocial variables in cancer survivors were acquired during an initial assessment prior to participation in a cancer rehabilitation program.
Methods: Cardiorespiratory fitness (VO2peak), fatigue (Piper Fatigue Scale, PFS), and depression (Beck Depression Inventory, BDI) were measured (N = 807; 67 ± 13 years). PA groups were divided by self-reported prior PA history (Group 1 = none; Group 2 &lt; 150 min/week; Group 3 ≥ 150 min/week).
Results: Significant (P &lt; 0.05) main effects for PA were observed among all variables except the PFS affective subscale. Groups 1 and 3 were significantly (P &lt; 0.05) different for BDI. Groups 1 and 3 were significantly (P &lt; 0.05) different for the total, sensory, and cognitive subscales of the PFS. Finally, Groups 1 and 3, and Groups 2 and 3 differed significantly (P &lt; 0.05) for the behavioral, sensory, and cognitive subscales of the PFS.
Conclusion: Cancer survivors with prior PA levels ≥ 150 min/week performed better on measures of VO2peak, were significantly less fatigued and depressed at initial assessment.
Pertumbuhan Lembaga Pendidikan Islam di Kerajaan Langkat Pada Tahun 1912-1942
Authors: Tanjung Muaz 
Published: May 2018

Before the establishment of the Islamic Kingdom of Langkat, the people there have embraced Islam. This is because Langkat is adjacent to Aceh, which had already been ruled by an Islamic empire and it broadcast Islam to various regions, including the east coast of Sumatra. The Kingdom of Langkat, especially after relocated its Capital to Tanjung Pura, had made Islam as a main reference and political legitimacy of the Sultan and the Kingdom in general. As a consequence, Islam is practiced by the majority of Muslim community and reflected in various fields. At the beginning of the 20th century in East Sumatra there emerged publicly funded educational institutions, including those in Langkat. However, religious subjects are not officially acknowledged. Seeing this situation, the Sultan and other Muslims felt responsible for establishing an independent Islamic educational institution. Although Islamic education was preiously taught to Muslim children, but its implementation was largely limited in mosques or private homes. The Kingdom was destined to improve the quality of Islamic education through building an independent educational institution.Keywords: Education, Islamic Empire, Langkat, Sumatera, Indonesia Sebelum berdirinya kerajaan Langkat, masyarakat di sana telah me­me­luk agama Islam. Hal ini dikarenakan wilayah Langkat berbatasan dengan Aceh yang telah memiliki kerajaan Islam dan menyiarkan Islam ke berbagai daerah, terutama di pantai timur Sumatera. Kerajaan Langkat terutama setelah berpusat di Tanjung Pura, menjadikan agama Islam sebagai pedoman dan legitimasi terhadap kebijakan-kebijakan sultan dan kerajaan secara umum. Masyarakat yang mayoritas beragama Islam dalam berbagai dinamika kehidupannya mencerminkan perilaku keislaman yang kuat. Di awal abad ke-20 M di Sumatera Timur banyak berdiri lembaga pendidikan umum, termasuk di Langkat. Namun demikian, pelajaran agama secara resmi tidak dibenarkan. Melihat keadaan ini, sultan dan umat Islam lainnya merasa bertanggungjawab untuk mendirikan lembaga pendidikan Islam yang berdiri sendiri. Meskipun pada masa sebelumnya pendidikan Islam tetap diajarkan kepada anak-anak Muslim, namun pelak­sanaannya masih berlangsung terbatas hanya di masjid atau rumah-rumah pribadi guru. Oleh karena itu Kerajaan Langkat terdorong untuk mening­katkan mutu pendidikan Islam dengan membangun lembaga pendidikan yang berdiri sendiri.Kata kunci: Pendidikan, Kerajaan Islam, Langkat, Sumatera, Indonesia

Published: May 2018

The aim of this paper is to determine the effects of acrobatic elements on changes in morphological characteristics in children who were experimentally treated. The sample consists of elementary school children from Kosovska Mitrovica N = 52, who regularly attend physical education classes and additional acrobatics trainings three times a week for the implementation of acrobatics in additional classes of physical education. The variables used to assess the circular dimensions and body mass are: Upper arm circumference expressed in cm (AONDL), calf circumference expressed in cm (AOPTK), chest circumference expressed in cm AOGRK, body weight expressed in kg (AMAST). The variables used to estimate the subcutaneous fat tissue are: Upper-arm skinfold expressed in mm (ANNDL), calf skinfold expressed in mm (ANPTK), Abdominal skinfold expressed in mm ANTRB. A t-test was used to determine statistically significant differences in variables (ANNDL p=.006), (ANPTK p=.005), (ANTRB p=.008). The obtained results can contribute to the rationalization of regular and additional teaching of physical education for the optimal planning and control of work.

Presents the results of empirical study, which was attended by 246 people of different age (112 men and 134 women), which living in Donetsk, Mariupol and Kiev. We used the following methods: 2 author’s research questionnaires; Impact of Event Scale (M. Horowitz, N. Wilner). Empirically it is shown that in a situation of military conflict in Ukraine in comparison with the period before the military conflict: 1) displaced persons from the combat zone and the people currently living in Mariupol emphasize the negative impact of the situation of the military conflict in Ukraine on the well-being of their family members; 2) increased aggressiveness and proneness to conflict has been observed among the participants of the study currently living in Mariupol and among the displaced persons from the combat zone; 3) the situation of the military conflict in Ukraine has been stressful for the study participants and their families, this is especially pronounced persons from the combat zone and the people currently living in Mariupol; 4) a fairly strong and very strong degree of sleep disorders has been observed among the participants of the study currently living in Mariupol, among the displaced persons from the combat zone and among the participants residing now in Donetsk; 5) irritation and anger in connection with the event – the military conflict in Ukraine – in rather strong and very strong degree have been observed among the participants of the study currently living in Mariupol, among the displaced persons from the combat zone and among the participants residing now in Donetsk. Empirical evidence shows that the most powerful influence of the situation of the military conflict in Ukraine on relations with the immediate relatives has been observed among the displaced persons from the combat zone, in comparison with other groups of research participants. 39,84% of all study participants indicate disappointment in the state, because the state does not protect the rights of citizens. Regarding the organization of the relationship between the citizen and the state respondents think that such relationships should be based: 1) on the protection of the rights of citizens; 2) on trust, honesty; 3) on respect for the Constitution. 21,95% of all study respondents indicated a lack of confidence in the government. 10,98 % of all study respondents note that they have increased aggression to politics. 13,01 % of all study respondents indicate that there is more to discuss military and political issues. 11,38 % of all study respondents have avoided the subject of war and militarypolitical events. 17,07 % of all study respondents began to perceive military and political-legal events are more critical with less confidence.
Temporalities of the Glitch: Déjà Vu
Authors: Cubitt Sean 
Published: May 2018

Glitch describes the visual and auditory effects of interruptions of electronic signals. Glitches may be caused by naturally occurring electromagnetic noise, by electromagnetic effects of the technology, or by errors in coding, storage or transmission. Glitches have been treated as noise by engineers, but used by artists to foreground the materiality of the medium in recording, transmission and reception. This chapter investigates these interruptions of image/signal, and the deliberate instigation or emulation of glitch effects in fiction, where typically they work to indicate the diegetic authenticity of fictional media, notably in the trans-temporal transmissions of Déjà Vu (Tony Scott, 2006), which forms the major case study. Foregrounding imperfection and the materiality of media, glitches interrupt the dominant temporal regimes of contemporary media and society.
The Plutino Population: An Abundance of Contact Binaries
Authors: Thirouin Audrey , Sheppard Scott S. 
Published: May 2018

Abstract
We observed 12 Plutinos over two separated years with the 4.3 m Lowell’s Discovery Channel Telescope. Here, we present the first light-curve data for those objects. Three of them (2014 JL80, 2014 JO80, and 2014 JQ80) display a large light-curve amplitude explainable by a single elongated object, but they are most likely caused by a contact binary system due to their light-curve morphology. These potential contact binaries have rotational periods from 6.3 to 34.9 hr and peak-to-peak light-curve variability between 0.6 and 0.8 mag. We present partial light curves, allowing us to constrain the light-curve amplitude and the rotational period of another nine Plutinos. By merging our data with the literature, we estimate that up to ∼40% of the Plutinos could be contact binaries. Interestingly, we found that all of the suspected contact binaries in the 3:2 resonance are small with absolute magnitude H > 6 mag. Based on our sample and the literature, up to ∼50% of the small Plutinos are potential contact binaries.
The Chemical Composition of NGC 5824, a Globular Cluster without Iron Spread but with an Extreme Mg–Al Anticorrelation*
Authors: Mucciarelli Alessio , Lapenna Emilio , Ferraro Francesco R. , Lanzoni Barbara 
Published: May 2018

Abstract
NGC 5824 is a massive Galactic globular cluster suspected to have an intrinsic spread in its iron content, according to the strength of the calcium triplet lines. We present chemical abundances of 117 cluster giant stars using high-resolution spectra acquired with the multi-object spectrograph FLAMES. The metallicity distribution of 87 red giant branch stars is peaked at [Fe/H] = −2.11 ± 0.01 dex, while that derived from 30 asymptotic giant branch stars is peaked at [Fe/H] = −2.20 ± 0.01 dex. Both the distributions are compatible with a null spread, indicating that this cluster did not retain the ejecta of supernovae. The small iron abundance offset between the two groups of stars is similar to the abundances already observed among red and asymptotic giant branch stars in other clusters. The lack of intrinsic iron spread rules out the possibility that NGC 5824 is the remnant of a disrupted dwarf galaxy, as previously suggested. We also find evidence of the chemical anomalies usually observed in globular clusters, namely the Na–O and the Mg–Al anticorrelations. In particular, NGC 5824 exhibits a huge range of [Mg/Fe] abundance, observed in only a few metal-poor and/or massive clusters. We conclude that NGC 5824 is a normal globular cluster, without spread in [Fe/H] but with an unusually large spread in [Mg/Fe], possibly due to an efficient self-enrichment driven by massive asymptotic giant branch stars.

Abstract
Most massive stars end their lives as red supergiants (RSGs), a short-lived evolutionary phase when they are known to pulsate with varying amplitudes. The RSG period–luminosity (PL) relation has been measured in the Milky Way, the Magellanic Clouds and M33 for about 120 stars in total. Using over 1500 epochs of R-band monitoring from the Palomar Transient Factory survey over a five-year period, we study the variability of 255 spectroscopically cataloged RSGs in M31. We find that all RGSs brighter than M

K
≈ −10 mag (log(L/L
⊙) > 4.8) are variable at Δm

R
> 0.05 mag. Our period analysis finds 63 with significant pulsation periods. Using the periods found and the known values of M

K
for these stars, we derive the RSG PL relation in M31 and show that it is consistent with those derived earlier in other galaxies of different metallicities. We also detect, for the first time, a sequence of likely first-overtone pulsations. Comparison to stellar evolution models from MESA confirms the first-overtone hypothesis and indicates that the variable stars in this sample have 12 M
⊙ < M < 24 M
⊙. As these RSGs are the immediate progenitors to Type II-P core-collapse supernovae (SNe), we also explore the implication of their variability in the initial-mass estimates for SN progenitors based on archival images of the progenitors. We find that this effect is small compared to the present measurement errors.
Modeling UV Radiation Feedback from Massive Stars. II. Dispersal of Star-forming Giant Molecular Clouds by Photoionization and Radiation Pressure
Authors: Kim Jeong-Gyu , Kim Woong-Tae , Ostriker Eve C. 
Published: May 2018

Abstract
UV radiation feedback from young massive stars plays a key role in the evolution of giant molecular clouds (GMCs) by photoevaporating and ejecting the surrounding gas. We conduct a suite of radiation hydrodynamic simulations of star cluster formation in marginally bound, turbulent GMCs, focusing on the effects of photoionization and radiation pressure on regulating the net star formation efficiency (SFE) and cloud lifetime. We find that the net SFE depends primarily on the initial gas surface density, Σ0, such that the SFE increases from 4% to 51% as Σ0 increases from 13 to

. Cloud destruction occurs within 2–10 Myr after the onset of radiation feedback, or within 0.6–4.1 freefall times (increasing with Σ0). Photoevaporation dominates the mass loss in massive, low surface density clouds, but because most photons are absorbed in an ionization-bounded Strömgren volume, the photoevaporated gas fraction is proportional to the square root of the SFE. The measured momentum injection due to thermal and radiation pressure forces is proportional to

, and the ejection of neutrals substantially contributes to the disruption of low mass and/or high surface density clouds. We present semi-analytic models for cloud dispersal mediated by photoevaporation and by dynamical mass ejection, and show that the predicted net SFE and mass loss efficiencies are consistent with the results of our numerical simulations.
Validating Semi-analytic Models of High-redshift Galaxy Formation Using Radiation Hydrodynamical Simulations

Published: May 2018

Abstract
We use a cosmological hydrodynamic simulation calculated with Enzo and the semi-analytic galaxy formation model (SAM) GAMMA to address the chemical evolution of dwarf galaxies in the early universe. The long-term goal of the project is to better understand the origin of metal-poor stars and the formation of dwarf galaxies and the Milky Way halo by cross-validating these theoretical approaches. We combine GAMMA with the merger tree of the most massive galaxy found in the hydrodynamic simulation and compare the star formation rate, the metallicity distribution function (MDF), and the age–metallicity relationship predicted by the two approaches. We found that the SAM can reproduce the global trends of the hydrodynamic simulation. However, there are degeneracies between the model parameters, and more constraints (e.g., star formation efficiency, gas flows) need to be extracted from the simulation to isolate the correct semi-analytic solution. Stochastic processes such as bursty star formation histories and star formation triggered by supernova explosions cannot be reproduced by the current version of GAMMA. Non-uniform mixing in the galaxy’s interstellar medium, coming primarily from self-enrichment by local supernovae, causes a broadening in the MDF that can be emulated in the SAM by convolving its predicted MDF with a Gaussian function having a standard deviation of ∼0.2 dex. We found that the most massive galaxy in the simulation retains nearby 100% of its baryonic mass within its virial radius, which is in agreement with what is needed in GAMMA to reproduce the global trends of the simulation.
The Propagation of Cosmic Rays from the Galactic Wind Termination Shock: Back to the Galaxy?
Authors: Merten Lukas , Bustard Chad , Zweibel Ellen G. , Tjus Julia Becker 
Published: May 2018

Abstract
Although several theories exist for the origin of cosmic rays (CRs) in the region between the spectral “knee” and “ankle,” this problem is still unsolved. A variety of observations suggest that the transition from Galactic to extragalactic sources occurs in this energy range. In this work, we examine whether a Galactic wind that eventually forms a termination shock far outside the Galactic plane can contribute as a possible source to the observed flux in the region of interest. Previous work by Bustard et al. estimated that particles can be accelerated to energies above the “knee” up to R
max = 1016 eV for parameters drawn from a model of a Milky Way wind. A remaining question is whether the accelerated CRs can propagate back into the Galaxy. To answer this crucial question, we simulate the propagation of the CRs using the low-energy extension of the CRPropa framework, based on the solution of the transport equation via stochastic differential equations. The setup includes all relevant processes, including three-dimensional anisotropic spatial diffusion, advection, and corresponding adiabatic cooling. We find that, assuming realistic parameters for the shock evolution, a possible Galactic termination shock can contribute significantly to the energy budget in the “knee” region and above. We estimate the resulting produced neutrino fluxes and find them to be below measurements from IceCube and limits by KM3NeT.
Differential Rotation in Solar-like Convective Envelopes: Influence of Overshoot and Magnetism
Authors: Beaudoin Patrice , Strugarek Antoine , Charbonneau Paul 
Published: May 2018

Abstract
We present a set of four global Eulerian/semi-Lagrangian fluid solver (EULAG) hydrodynamical (HD) and magnetohydrodynamical (MHD) simulations of solar convection, two of which are restricted to the nominal convection zone, and the other two include an underlying stably stratified fluid layer. While all four simulations generate reasonably solar-like latitudinal differential rotation profiles where the equatorial region rotates faster than the polar regions, the rotational isocontours vary significantly among them. In particular, the purely HD simulation with a stable layer alone can break the Taylor–Proudman theorem and produce approximately radially oriented rotational isocontours at medium to high latitudes. We trace this effect to the buildup of a significant latitudinal temperature gradient in the stable fluid immediately beneath the convection zone, which imprints itself on the lower convection zone. It develops naturally in our simulations as a consequence of convective overshoot and rotational influence of rotation on convective energy fluxes. This favors the establishment of a thermal wind balance that allows evading the Taylor–Proudman constraint. A much smaller latitudinal temperature gradient develops in the companion MHD simulation that includes a stable fluid layer, reflecting the tapering of deep convective overshoot that occurs at medium to high latitudes, which is caused by the strong magnetic fields that accumulate across the base of the convection zone. The stable fluid layer also has a profound impact on the large-scale magnetic cycles developing in the two MHD simulations. Even though both simulations operate in the same convective parameter regime, the simulation that includes a stable layer eventually loses cyclicity and transits to a non-solar, steady quadrupolar state.
