Pengaruh Metode Card Sort Dalam Meningkatan Hasil Belajar Al Qur’an Hadits Siswa Kelas IV di Madrasah Ibtidaiyah Muhammadiyah 07 Sidokelar Paciran
Authors: M. Chotibuddin Sintiya Mafazatin 
Published: June 2022

The purpose of this study was to improve student learning outcomes for the fourth grade Al-Qur’an Hadith subjects through the Card Sort method at MI Muhammadiyah 07 Sidokelar.
This study uses quantitative methods with parametric statistical data analysis techniques, and uses a one-group pretest posttest design. This research was conducted at MI Muhammadiyah 07 Sidokelar in the even semester of the 2020/2021 school year. The selected population is class IV with a total of 17 people. From that population, samples were taken using a saturated sampling technique (if the population is less than 30) then the sample was class IV students of MI Muhammadiyah 07 Sidokelar Paciran as many as 17 people. The data collection instruments used were observation and test methods.
In the presentation of the acquisition value in the observation of learning activities using the card sort method, an average value of 81.81% was obtained, this means that the card sort method in learning can be implemented well. While the test results data that have been collected were analyzed using validity test techniques, reliability tests, normality tests, homogeneity tests, and strengthened using product moment correlation tests, as well as significance tests or t-tests (t-test). From the results of the data analysis that has been carried out, there is a significant correlation between the X variable and the Y variable. As indicated by the correlation coefficient rcount of 0.864 and rtable of 0.514, rcount > rtable (0.864 > 0.514). And based on the results of the significance test or t-test (t-test) obtained a tcount value of 6.648 and a t-table value of 2.131. Then tcount > ttable (6,648 > 2,131). So it can be concluded that H0 is rejected and Ha is accepted. So the card sort method has an effect on increasing student learning outcomes in the subjects of Al Qur’an Hadith on the legal material of idgham and iqlab reading in class IV MI Muhammadiyah 07 Sidokelar Paciran for the 2020/2021 school year.
Furthermore, the calculation is carried out using the coefficient of determination formula to find out how big the contribution of the influence of variable X to variable Y. Using the formula KP = r2 x 100%, the results obtained are 74.6% of the contribution of variable X to variable Y.

Abstract
The stellar initial mass function (IMF) is a fundamental property in the measurement of stellar masses and galaxy star formation histories. In this work, we focus on the most massive galaxies in the nearby universe

. We obtain high-quality Magellan/LDSS-3 long-slit spectroscopy with a wide wavelength coverage of 0.4–1.01 μm for 41 early-type galaxies (ETGs) in the MASSIVE survey and derive high signal-to-noise spectra within an aperture of R
e/8. Using detailed stellar synthesis models, we constrain the elemental abundances and stellar IMF of each galaxy through full spectral modeling. All the ETGs in our sample have an IMF that is steeper than a Milky Way (Kroupa) IMF. The best-fit IMF mismatch parameter, α
IMF = (M/L)/(M/L)MW, ranges from 1.1 to 3.1, with an average of 〈α
IMF〉 = 1.84, suggesting that on average, the IMF is more bottom heavy than Salpeter. Comparing the estimated stellar masses with the dynamical masses, we find that most galaxies have stellar masses that are smaller than their dynamical masses within the 1σ uncertainty. We complement our sample with lower-mass galaxies from the literature and confirm that

Extending the Fisher Information Matrix in Gravitational-wave Data Analysis
Authors: Wang Ziming , Liu Chang , Zhao Junjie , Shao Lijing 
Published: June 2022

Abstract
The Fisher information matrix (FM) plays an important role in forecasts and inferences in many areas of physics. While giving fast parameter estimation with Gaussian likelihood approximation in the parameter space, the FM can only give the ellipsoidal posterior contours of the parameters and it loses the higher-order information beyond Gaussianity. We extend the FM in gravitational-wave (GW) data analysis by using the Derivative Approximation for LIkelihoods (DALI), a method to expand the likelihood, while keeping it positive definite and normalizable at every order, for more accurate forecasts and inferences. When applied to two real GW events, GW150914 and GW170817, DALI can reduce the difference between the FM approximation and the real posterior by 5 times in the best case. The calculation times of DALI and the FM are at the same order of magnitude, while obtaining the real full posterior will take several orders of magnitude longer. Besides more accurate approximations, higher-order correction from DALI provides a fast assessment of the FM analysis and gives suggestions for complex sampling techniques that are computationally intensive. We recommend using the DALI method as an extension to the FM method in GW data analysis to pursue better accuracy while still keeping the speed.

Abstract
We present a beam pattern measurement of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) made using the Sun as a calibration source. As CHIME is a pure drift-scan instrument, we rely on the seasonal north–south motion of the Sun to probe the beam at different elevations. This semiannual range in elevation, combined with the radio brightness of the Sun, enables a beam measurement that spans ∼7200 square degrees on the sky without the need to move the telescope. We take advantage of observations made near solar minimum to minimize the impact of solar variability, which is observed to be <10% in intensity over the observation period. The resulting data set is highly complementary to other CHIME beam measurements—both in terms of angular coverage and systematics—and plays an important role in the ongoing program to characterize the CHIME primary beam.
Analytical Model of Disk Evaporation and State Transitions in Accreting Black Holes
Authors: Cho 조 Hyerin 혜린 , Narayan Ramesh 
Published: June 2022

Abstract
State transitions in black hole X-ray binaries are likely caused by gas evaporation from a thin accretion disk into a hot corona. We present a height-integrated version of this process, which is suitable for analytical and numerical studies. With radius r scaled to Schwarzschild units and coronal mass accretion rate

Variability of the Reconnection Guide Field in Solar Flares
Authors: Dahlin Joel T. , Antiochos Spiro K. , Qiu Jiong , DeVore C. Richard 
Published: June 2022

Abstract
Solar flares may be the best-known examples of the explosive conversion of magnetic energy into bulk motion, plasma heating, and particle acceleration via magnetic reconnection. The energy source for all flares is the highly sheared magnetic field of a filament channel above a polarity inversion line (PIL). During the flare, this shear field becomes the so-called reconnection guide field (i.e., the nonreconnecting component), which has been shown to play a major role in determining key properties of the reconnection, including the efficiency of particle acceleration. We present new high-resolution, three-dimensional, magnetohydrodynamics simulations that reveal the detailed evolution of the magnetic shear/guide field throughout an eruptive flare. The magnetic shear evolves in three distinct phases: shear first builds up in a narrow region about the PIL, then expands outward to form a thin vertical current sheet, and finally is transferred by flare reconnection into an arcade of sheared flare loops and an erupting flux rope. We demonstrate how the guide field may be inferred from observations of the sheared flare loops. Our results indicate that initially the guide field is larger by about a factor of 5 than the reconnecting component, but it weakens by more than an order of magnitude over the course of the flare. Instantaneously, the guide field also varies spatially over a similar range along the three-dimensional current sheet. We discuss the implications of the remarkable variability of the guide field for the timing and localization of efficient particle acceleration in flares.
X-Ray Studies of the Inverted Ejecta Layers in the Southeast Area of Cassiopeia A
Authors: Tsuchioka Tomoya , Sato Toshiki , Yamada Shinya , Uchiyama Yasunobu 
Published: June 2022

Abstract
The central strong activities in core-collapse supernovae are expected to produce the overturning of the Fe- and Si/O-rich ejecta during the supernova explosion based on multidimensional simulations. X-ray observations of the supernova remnant Cassiopeia A have indicated that the Fe-rich ejecta lies outside the Si-rich materials in the southeastern region, which is consistent with the hypothesis on the inversion of the ejecta. We investigate the kinematic and nucleosynthetic properties of the inverted ejecta layers in detail to understand its formation process using the data taken by the Chandra X-Ray Observatory. Three-dimensional velocities of Fe- and Si/O-rich ejecta are obtained as >4500 km s−1 and ∼2000–3000 km s−1, respectively, by combining proper motion and line-of-sight velocities, indicating that the velocity of the Si/O-rich ejecta is slower than that of the Fe-rich ejecta from the early stages of the explosion. To constrain their burning regime, the Cr/Fe mass ratios are evaluated as

% in the outermost Fe-rich region and

% in the inner Fe/Si-rich region, suggesting that the complete Si burning layer is invertedly located to the incomplete Si burning layer. All the results support the ejecta overturning at the early stages of the remnant’s evolution or during the supernova explosion of Cassiopeia A.
Modeling Electron Acceleration and Transport in the Early Impulsive Phase of the 2017 September 10th Solar Flare
Authors: Li Xiaocan , Guo Fan , Chen Bin , Shen Chengcai , Glesener Lindsay 
Published: June 2022

Abstract
The X8.2-class limb flare on 2017 September 10 is among the best studied solar flare events owing to its great similarity to the standard flare model and the broad coverage by multiple spacecraft and ground-based observations. These multiwavelength observations indicate that electron acceleration and transport are efficient in the reconnection and flare looptop regions. However, there lacks a comprehensive model for explaining and interpreting the multi-faceted observations. In this work, we model the electron acceleration and transport in the early impulsive phase of this flare. We solve the Parker transport equation that includes the primary acceleration mechanism during magnetic reconnection in the large-scale flare region modeled by MHD simulations. We find that electrons are accelerated up to several MeV and fill a large volume of the reconnection region, similar to the observations shown in microwaves. The electron spatial distribution and spectral shape in the looptop region agree well with those derived from the microwave and hard X-ray emissions before magnetic islands grow large and dominate the acceleration. Future emission modelings using the electron maps will enable direct comparison with microwave and hard X-ray observations. These results shed new light on the electron acceleration and transport in a broad region of solar flares within a data-constrained realistic flare geometry.
Retinal Folds as a Clinical Feature of X-Linked Retinoschisis: A Series of Three Cases
Authors: Laura Diana M. , Ashkenazy Noy , Anzaldo Estephania Feria , Negron Catherin I. , Berrocal Audina M. 
Published: June 2022

BACKGROUND AND OBJECTIVE:
The most common clinical features of X-linked retinoschisis (XLRS) include macular schisis in a spoke wheel pattern and peripheral schisis, though other findings such as vitreous veils, vascular attenuation, and subretinal fibrosis have been described. This is the first report to describe retinal folds as a characteristic feature in patients with XLRS.

PATIENTS AND METHODS:
This was a case series of patients presenting to the retina service at Bascom Palmer Eye Institute with genetically confirmed XLRS. Patients included in this report underwent examination under anesthesia with multimodality imaging.

RESULTS:
Three patients with XLRS were found to have retinal folds, including a newly characterized “retinal scroll” seen on examination and multimodality imaging.

CONCLUSIONS:
The presence of a retinal fold should yield a differential diagnosis that includes XLRS in the correct clinical context. Panel-based genetic testing and multimodal imaging are useful in guiding clinical management.

Experiences of Athletic Trainers in Tactical Athlete Settings When Managing Patients With Mental Health Conditions
Authors: Loveless Amy M. , Games Kenneth E. , Shea Maura E. , Thews Kami N. , Winkelmann Zachary K. 
Published: June 2022

Context
Researchers have demonstrated that job demands impair tactical athletes’ mental health. Mental health stigmas in this population and limited resources may prevent individuals from receiving care. Athletic trainers (ATs) are often the first, and sometimes the only, contact for mental health concerns. Previous literature indicated that ATs desired more psychosocial training and experience.

Objective
To investigate ATs’ preparedness and experiences managing patients with mental health conditions in the tactical athlete setting.

Design
Consensual qualitative research study.

Setting
One-on-one, semistructured interviews.

Patients or Other Participants
Fifteen ATs (men = 7, women = 8; age = 36 ± 10 years; experience in tactical athlete setting = 4 years [range, 6 months–20 years]; military = 12, law enforcement = 2; fire service = 1).

Main Outcome Measure(s)
Interviews followed a 9-question protocol focused on job setting preparation, mental health training, and perceived role managing patients with mental health concerns. Interviews were audio recorded and transcribed verbatim. A 3-person coding team convened for data analysis following the consensual qualitative research tradition. Credibility and trustworthiness were established using a stability check, member checking, and multianalyst triangulation.

Results
Four domains emerged surrounding ATs’ mental health management experiences with tactical athletes: (1) population norms, (2) provider preparation, (3) provider context, and (4) structure of job responsibilities. Most ATs felt their educational experiences lacked comprehensive mental health training. Some participants described formal employer resources that were optional or mandatory for their job, whereas others engaged in self-education to feel prepared for this setting. Participants shared that unfamiliar experiences, such as divorce and deployment, influenced their context as providers. Most ATs had no policy related to mental health care and referral, indicating it was outside their responsibilities or they were unsure of role delineation.

Conclusions
For ATs working with tactical athletes, our respondents suggested that additional mental health education and training are necessary. They also indicated that improvement is needed in job structure regarding role delineation and the establishment of policies regarding behavioral health.
SERTÃO NA LITERATURA E NO CINEMA CONTEMPORÂNEOS:
Authors: Pimenta Patrício Francisco Heitor , Negrão Berlini de Andrade Ana Carolina 
Published: June 2022

O presente trabalho busca analisar criticamente como a figura do Sertão foi representada na literatura nacional e no cinema, partindo do pressuposto que este é um elemento recorrente em nossas artes desde as primeiras manifestações literárias nacionais. Objetiva-se, principalmente, analisar como se dá a ressignificação da representação do sertão, o qual, na literatura e no cinema contemporâneos, ganham uma nova roupagem, muitas vezes livres dos estereótipos comuns ao regionalismo. Esse sertão ressignificado pode ser percebido a partir do corpus do presente trabalho, no qual visamos analisar os contos da obra Faca e Livro dos Homens (2017), de Ronaldo Correia de Brito, e o filme Viajo porque preciso, volto por te amo (2009) de Marcelo Gomes e Karim Aïnouz. Para tal proposta, utilizaremos teóricos como Santini (2009, 2014, 2017), Galvão (2000), Moraes (2009), Arrigucci Jr. (2000), entre outros.
Prevalence of Under-Five and Infant Outpatients in the University of Cape Coast Hospital: An Empirical Application of Applied Univariate Statistical Modelling
Authors: Bakr McAdams Abu , Prah James Kojo , Nkrumah Kwasi Sobre , Walker Emmanuel , Lasim Obed 
Published: June 2022

Background: The healthcare needs of under-fives and infants create major public health and development challenges in Ghana. Though some level of progress has been achieved in the area, there still exist several challenges to be addressed with regard to the survival and development of these vulnerable age groups. One module used in this domain is to monitor, assess, and evaluate the healthcare needs of infants and under-fives in healthcare facilities. Although the literature has dealt greatly with child healthcare in Ghana very little has been done in the area of modelling and forecasting the prevalence of infant and under-five outpatients’ healthcare needs across hospitals in the country.
Purpose: This study was conducted to assess, model, and probably predict the outpatient performance variable for infants and under-fives in the University of Cape Coast Hospital.
Methodology: Quantitative methods and a longitudinal research design were used in this study. Monthly data of infant and under-five outpatients covering January 2012 through December 2021 was sourced from the District Health Information Management System (DHIMS II) constituting a total sample size of 120 observations. The classical Box-Jenkins method of applied univariate statistical modelling was used to analyze the data.
Findings: This unbiased study revealed in its findings 100 competitive models for the data. A seasonal autoregressive moving average model SARIMA (2, 0, 3)(1, 0, 1)12 emerged as the best fitting model for the data with the lowest AIC value. The Ljung-Box Q-test for serial correlation indicated p-values > 0.05 meaning that the model exhibited white noise in its residuals. The findings revealed seasonality but no trend with seasonal peaks in March, July, and November every year.
Unique contribution to theory and practice: A seasonal autoregressive moving average model SARIMA (2, 0, 3)(1, 0, 1)12 emerged as the best fitting model predicting under-five and infant visits to the outpatient department. This model will logistically guide the management of the hospital to prudently and effectively allocate human and material resources to the paediatric unit of the hospital. Further studies are recommended to investigate why there are seasonal peaks in the months of March, July, and November every year so that appropriate public health interventions can be applied to mitigate the situation.
