Authors: علي أسماء محمد
Published: April 2023

تهدف هذه الدراسة إلى حصر المسائل التي اختص بها الرجل في أحكام الأسرة، وقد جعلتُ ذلك في أربعة مباحث، تحدثتُ فيهم عن انفراد الرجل عن المرأة في ولاية النكاح، والزواج بالكتابيات، ثم تطرقتُ بعد ذلك إلى الحديث عن المهر, والقوامة, والنفقة, وعن تعدد الزوجات, ثم ختمتُ هذا البحث بالطلاق والظهار كونهما لا يقعا إلا من الرجل، وقد كانت أبرز النتائج في ذلك أنه يجوز للرجل أن يزوج نفسه بدون ولي، كما أباحت له الشريعة الإسلامية الزواج من الكتابية، وفرضت عليه المهر، وجُعِلت له القوامة، وأُوجبت عليه النفقة، وأُبيح له تعدد الزوجات إلى أربع كحد أقصى، وجُعِلت عصمة الطلاق بيده، وقد اعتمدت في الحكم على أقوال المذاهب الإسلامية المشهورة (الحنفية- المالكية – الشافعية- الحنابلة) مع التطرق إلى المذهب الظاهري حيثما وجد، وكنتُ أضيف رأيي بعد ذكر أقوالهم, وهو جُلَّ ما توصلت إليه خلال مدة البحث والقراءة, وأخيراً ذيلت البحث بالخاتمة التي أوردت فيها النتائج، وبعض التوصيات التي قد تفيد الرجل المسلم، والباحثين، ثم ألحقت ذلك بالمصادر والمراجع التي اعتمدتُ عليها في هذا البحث.

The Effects Of Differing Density Of Swim-Training Sessions On Shoulder Range Of Motion and Isometric Force Production In National and University Level Swimmers
Authors: Yoma Matias , Herrington Lee , Mackenzie Tanya
Published: April 2023

Background

Well-developed physical qualities (i.e., greater load capacity) in athletes can provide protection against injuries. Although higher competitive level swimmers have more developed physical qualities, no studies have investigated how physical qualities of the shoulder respond to a swim-training session in different competitive levels.

Purpose

To compare baseline shoulder external rotation range of motion (ER ROM) and isometric peak torque of the shoulder internal rotators (IR) and external rotators (ER) between national and university level swimmers with differing training volumes. To compare the post-swim changes of these physical qualities between groups.

Study design

Cross-sectional.

Methods

Ten male swimmers (age= 18.7 ± 1.2 years) were divided into high-load (N= 5 national-level, weekly swim-volume= 37.0 ± 2.7 km) and low-load groups (N= 5 university-level, weekly swim-volume= 6.8 ± 1.8 km). For each group, shoulder active ER ROM and isometric peak torque of the shoulder IR and ER were measured before and immediately after a high-intensity swim-training session (for each group, the hardest swim-session of the week was analyzed). The results were evaluated by the level of significance (p-value), effect size, and whether changes exceeded the measurement error.

Results

University-level swimmers had lower baseline ER torque (p= 0.006; d= 2.55) and IR torque (p= 0.011; d= 2.42) than national-level swimmers. For post-swim analysis, ER ROM decreased more in university swimmers (change= -6.3° to -8.4°; d= 0.75-1.05) than national counterparts (change= -1.9° to -5.7°; d= 0.43-0.95). Greater drops in rotation torque were found in university swimmers (IR change= -15% to -21.0%; d= 0.83-1.66; ER change= -9.0% to -17.0%; d= 1.14-1.28) compared to national swimmers (IR change= -10.0% to -13.0%; d= 0.61-0.91; ER change= -3.7% to -9.1%; d= 0.50-0.96). The average change of all tests in university swimmers exceeded the minimal detectable change (MDC), whereas in national level swimmers some tests exceeded the MDC. Despite this, only post-swim ER torque in the dominant side (p= 0.003; d= 1.18) was significantly lower in university swimmers (possibly due to the small sample size).

Conclusions

University swimmers have less baseline shoulder external and internal rotator torque and had greater drops of all shoulder physical qualities after a swim-training session, which may have implications for injury risk. However, due to the sample size, the results have to be interpreted with caution.

PENGARUH LATIHAN SMALL SIDED GAMES DAN LATIHAN RONDO TERHADAP KETEPATAN PASSING PADA PEMAIN KLUB FUTSAL ALDIFA BANJARMASIN
Authors: Fitrian Zanzabil Adwa
Published: April 2023

This study was conducted to determine the effect of the Small Sided Games (SSG) and Rondo exercises on the accuracy of passing on the players of the Futsal club Aldifa Banjarmasin. The experimental method used in this research is the "Two Group Pre-test and Post-test Design" research design. The sample in this study amounted to 20 people with a sampling technique using purposive sampling technique. The treatment grouping was done using MSOP (Match Subject Ordinal Pairing). The research instrument used the development of a test instrument to measure football ability which was adopted from DR. Norbert Rogalski and DR. Ernst Dagel. Data analysis in this study used prerequisite tests which included normality and homogeneity tests. The data obtained from the initial test and final test of graduation accuracy that have gone through the prerequisite test stage are followed by hypothesis testing using the t-test. The value of the SSG group hypothesis test was obtained (6,678 > 2,262), while the rondo group hypothesis test was obtained (2,372 > 2,262). Thus from these results prove that there is a significant effect of each of these exercises. The results of the t-test were obtained (1.310 < 2.101), thus the results of the t-test showed that there was no significant difference between the two groups. However, if it is seen from the number of differences in the average posttest of the group where the SSG is 6.80 while Rondo is 5.90, so it has a difference of 0.900 which is higher in the SSG group. So these results prove that the two training methods in this study have the same effect, but the SSG group has a better effect in terms of passing accuracy compared to Rondo training on Aldifa Banjarmasin futsal club players.

Incidents of injuries that were experienced by track and field athletes in training and matches that are not handled properly. As a result, injury recovery is not always ideal, putting athletes at risk for more serious injuries. This study aims to evaluate the types and treatment of injuries that occur in athletes from the Indonesian Athletics Association (PASI) in East Java Province. This research was conducted in cross-sectional with descriptive and comparative data analysis methods. There were 141 athletic athletes aged 17.97 ± 2.314 years participated in this study. Different test analysis was carried out based on gender, age, and number of competitions that were followed. The instrument used is a questionnaire whose statement items have been tested for validity using Pearson Product Moment and show valid results (p-value <0.05). The results of the normality test showed that the data did not have a normal distribution (p-value <0.05). The non-parametric test showed no significant differences in the perception of injury management based on gender, age, and match number (p-value > 0.05). Furthermore, on the athlete's knowledge, the majority of athletes still believe in traditional handling and do not know first aid for injuries using the Rest, Ice, Compression and Elevation (RICE) method.

Published: April 2023

This study aimed to assess the reading curriculum in Philippine basic education. It specifically focused on determining the reading competencies, the approaches in reading instruction and assessments before and during COVID-19, and the alignment of the written and intended to the implemented and assessed curriculum. This qualitative research employed the following data gathering techniques: document analysis, online focus group discussion, and constructive alignment checklist. Findings reveal that the basic education curriculum includes reading competencies categorized into text processing and task management competencies. In terms of the reading levels, it was found that there are more instructional readers than independent readers in basic education. Further, a number of students from different year levels, including in the secondary level, were also found to be non-readers. Regarding the approaches to reading instruction and assessment, the approaches were more extensive, varied, and teacher-directed before the COVID-19 pandemic involving class and group dynamics, while in the new normal, teachers employed self-paced/independent reading using printed modules and a few digital reading resources. Finally, the curriculum assessment reveals that there is generally a low alignment between the written, assessed, and delivered curriculum in reading. This implies that there are learning outcomes specified in the K-12 curriculum guide that have not been processed and assessed by teachers.

You Are Whatever I Say You Are:
Authors: Palsky Robin
Published: April 2023

This article analyzes the fluidity of Black identities created, maintained, and destroyed by white plantation holders to maintain white supremacy and economic advantages. It argues that as wealth began to flow from plantations, the identities of enslaved individuals morphed. From heathen, ‘brutish,’ wild peoples needing to be controlled to chattel property able to be manipulated and bred, to rebels and fugitives whose actions justified violence to maintain white dominance and economic status quo. This article seeks to demonstrate how contemporary Black identities within the greater society continue to be influenced by religious and codified identities enacted by white men in power. It asks us to critically engage with how we are implicit in enforcing specific identities onto Black bodies. Through this analysis, the link between wild heathens and violent criminals within societal perceptions can be illustrated.

This type of research is Research and Development (R&D) with the 4D development model (Define, Design, Development, and Disseminate). The research subjects were 70 Grade VII students of SMPN, NTB. The results of the Guided Inquiry-based E-Module feasibility test ranged from 89.56% to the very feasible category. This shows that the E-Module can be used as an instrument or learning media. Meanwhile, the results of the practicality test of the E-Module based on Guided Inquiry Learning based on student responses ranged from 88.32% in the very practical category, while the teacher's responses ranged from 93.04% to the very practical category. The test results for the effectiveness of using the Guided Inquiry-based E-Module are shown by the Gain-Score obtained by students after using the E-Module. This can be seen from the Gain score obtained by the experimental class ranging from 78.03% which indicates that the media is quite effective in learning. This can be seen from the Asymp value. Sig. (2-Tailed) ranges from 0.000 <0.05, meaning that there is a significant difference in the analytic abilities of students using guided inquiry learning-based E-Modules.

Published: April 2023

This study aims to determine the effect of blended learning virtual learning models on PhET-assisted fluid material on students' conceptual comprehension. The design model used in this research is an experiment with a pretest-posttest type. The sample used in this study was Class XI IPA C as the experimental object consisting of 35 students in one class. The test given was in the form of a concept comprehension ability test consisting of 10 multiple choice questions with a maximum score of 100. The results showed that the average posttest score was higher than the average pretest score in the experimental class. In addition, an N-gain value of 0.62 was obtained, which means that the value of increasing student learning outcomes using the phet-assisted virtual blended learning model is in the medium category. This shows that the use of PhET-assisted blended learning virtual models has an effect on students' mastery of concepts.

Abstract. The primary factor leading to insulin resistance (IR) and type 2 diabetes mellitus (T2DM) is oxidative stress. Despite its liver-protecting, enzyme-lowering, immune-regulating, and antiviral effects, the impact of picroside I on oxidative stress, glucose utilization, and IR has not been investigated yet. In vitro studies were conducted to evaluate the antioxidant properties of different concentrations of picroside I. The results showed that picroside I effectively suppresses α-glucosidase and α-amylase with IC50 values of 109.75 μg/mL and 160.71 μg/mL in the range of 50-500 μg/mL. Additionally, when IR-HepG2 cells were treated with 80 μg/mL of picroside I, it was found to have little effect on cell viability, increase glucose consumption, decrease the levels of the free radical metabolite malonic dialdehyde, and increase superoxide dismutase activity. These findings indicate that picroside I has the potential to regulate oxidative stress in IR-HepG2 cells, potentially improving IR and exhibiting anti-T2DM activity.
Resumen. El factor principal que conduce a la resistencia a la insulina (IR) y a la diabetes mellitus tipo 2 (T2DM) es el estrés oxidativo. A pesar de sus efectos protectores del hígado, reductores de enzimas, inmunorreguladores y antivirales, aún no se ha investigado el impacto del picrósido I sobre el estrés oxidativo, la utilización de glucosa y la IR. Se realizaron estudios in vitro para evaluar las propiedades antioxidantes de diferentes concentraciones de picrósido I. Los resultados mostraron que el picrósido I suprime eficazmente la α-glucosidasa y la α-amilasa con valores IC50 de 109,75 μg/mL y 160,71 μg/mL en el rango de 50 -500 microgramos/ml. Además, cuando las células IR-HepG2 se trataron con 80 μg/mL de picrósido I, se encontró que tenía poco efecto sobre la viabilidad celular, aumentaba el consumo de glucosa, disminuía los niveles del metabolito de radicales libres dialdehído malónico y aumentaba la actividad de la superóxido dismutasa. Estos hallazgos indican que el picrósido I tiene el potencial de regular el estrés oxidativo en las células IR-HepG2, mejorando potencialmente la IR y exhibiendo actividad anti-T2DM.

In this paper, we interested in Wilker inequalities. We provide finer bounds than known previous. Moreover, bounds are obtained for the following trigonometric function $$g_n(x) = \left(\frac{\sin(x)}{x}\right)^2 \left( 1 - \frac{2\left(\frac{2 x}{\pi}\right)^{2n+2}}{1-(\frac{2x}{\pi})^2}\right) +\frac{\tan(x)}{x}, \ n\geq 0.$$

Published: April 2023

Non-orthogonal Multiple Access (NOMA) is a multiple-access technique allowing multiusers to share the same communication resources, increasing spectral efficiency and throughput. NOMA has been shown to provide significant performance gains over orthogonal multiple access (OMA) regarding spectral efficiency and throughput. In this paper, two scenarios of NOMA are analyzed and simulated, involving two users and multiple users (four users) to evaluate NOMA's performance. The simulated results indicate that the achievable sum rate for the two users’ scenarios is 16.7 (bps/Hz), while for the multi-users scenario is 20.69 (bps/Hz) at transmitted power of 25 dBm. The BER for two users’ scenarios is 0.004202 and 0.001564 for user 1 and user 2, respectively, while the BER for multi-users scenario are 0.001738, 0.000706, 0.000286, and 0.000028 for user 1, user 2, user 3, and user 4 respectively. In addition, this paper has compared NOMA with OMA in terms of achievable sum rate. The obtained results indicate that an improvement is achieved for two users NOMA (16.7 (bps/Hz)) compared with OMA (15.53(bps/Hz)), while for multi-users NOMA (20.69 (bps/Hz)) compared with OMA (15.79 (bps/Hz)) at transmitted power of 25 dBm.
Photosynthetically Active Radiation Separation Model for High-Latitude Regions in Agrivoltaic Systems Modelling

Published: April 2023

Photosynthetically active radiation is a key parameter for modelling the photosynthetic behaviour of plants in response to sunlight and, subsequently, for determining crop yield. Separating photosynthetically active radiation into direct and diffuse components is of significance to agrivoltaic systems, which combine solar energy conversion and agricultural farming on the same portion of land. Placing photovoltaic on agricultural land results in varying shading conditions throughout the day and seasons, producing a higher contribution of incident diffuse radiation to the crops beneath the system in these shaded regions. Additionally, photosynthesis is more efficient under conditions of diffuse radiation than direct radiation per unit of total photosynthetically active radiation. This study introduces a new separation model capable of accurately estimating the diffuse component from the global photosynthetically active radiation and conveniently retrievable meteorological parameters. The model builds upon one of the currently most performing separation models for decomposing global solar radiation into diffuse radiation, the YANG2 model. Four new predictors, found relevant in the literature to influence diffuse photosynthetically active radiation, are added: optical thickness, vapour pressure deficit, aerosol optical depth, and surface albedo. The proposed model has been calibrated, tested, and validated at three sites in Sweden with latitudes above 58° N, outperforming four other models in all examined locations, with R2 values greater than 0.90. To alleviate the scarcity of photosynthetically active radiation studies in high-latitude regions, the seasonal trends and variation of the various radiation components are analysed. To demonstrate the applicability of the developed model, the location of Sweden's first agrivoltaic system is used to assess a variety of cases that take into account the various data availability that is representative of current and future agrivoltaic systems. In cases where in-situ measurements of diffuse photosynthetically active radiation are not available, the results indicate that the model can be utilised and adjusted for adjacent stations. Utilising predictor values derived from satellite data is an alternative method, but the spatial resolution must be considered with caution.
Understanding and Preventing Climate Breakdown: A Guide for Social and Behavioral Scientists
Authors: Dablander Fabian
Published: April 2023

Despite decades of scientific warnings, there is insufficient action to prevent climate breakdown. This is true at the government and corporate level, where we see the expansion of fossil fuel infrastructure, and at the individual level, where only a small proportion of the general public and the wider academic community engage in climate advocacy or activism. The latter is starting to change. Indeed, the enormous dangers ahead, coupled with the inadequacy of the political response, call for a reevaluation of the role of scientists and academics on a planet in crisis. In this paper, I (a) provide a concise assessment of our current predicament, (b) detail the ways in which both current as well as aspirational climate policy and mitigation pathways are insufficient to prevent climate breakdown, (c) sketch what climate policy commensurate with the scale of the challenge might look like, and (d) suggest ways in which scientists and academics in general, and social and behavioral scientists in particular, can get (more) involved to help secure a livable and sustainable future for all.
Empowering a Sustainable Future: Fostering Sustainable Behavior with Targeted Interventions
Authors: Krefeld-Schwalb Antonia , Gabel Sebastian
Published: April 2023

The year 2022 was one of the warmest years ever recorded, illustrating theaccelerating effects of climate change. There is widespread scientific consensus that action must be taken to reduce greenhouse gas emissions from individual behavior, so policymakers increasingly use behavioral interventions to encourage consumers’ adoption of sustainable behaviors. However, changing behavior is difficult and interventions that have the goal of increasing sustainable behavior are often not effective. Predominant "one-size-fits-all" approaches that provide the same interventions to all consumers fail to take into account that consumers have different motives for engaging in sustainable behaviors and often respond differently to interventions. The goal of this project is to develop a deep machine learning approach that policymakers can use to personalize behavioral interventions. We combine lab studies and a large field experiment to design an approach for targeting interventions that accounts for individual responsiveness to interventions, motives for and against sustainable behaviors, as well as interactions between sustainable behaviors. The insights from this project advance our theoretical understanding of heterogeneous treatment effects towards sustainability and provide practical guidance for policymakers to trigger behavioral change more effectively.

Although limited research suggests that infants can behave prosocially even before their first birthdays, the prevalence and characteristics of these early prosocial behaviors remain unexplored. Indeed, very few studies of prosocial development have included 12-month-old infants or examined how prosociality changes across the second year, and none has assessed individual differences in prosocial strategy use. This study investigated prosocial helping and comforting behaviors in a racially and socioeconomically diverse sample of 221 11- to 20-month-olds (45.2% female; 61% Black; 67.3% low socioeconomic status). At 12 months (n=154), >80% of infants helped an experimenter retrieve out-of-reach items and ~60% comforted their mother in distress. Modest increases in helping were observed across the second year of life. Individual differences in specific helping strategies were detected. Infants who helped by handing an item to an experimenter on one task (rather than placing the item in a target location) also used greater handing on another task; similar patterns were found with placing. Moreover, type of strategy was associated with age and sex: older infants and male infants used more placing. No relation between helping and comforting was detected, indicating that these prosocial subdomains are distinct during infancy. The high rates of helping by 12-months of age and use of individual helping strategies demonstrate that infants have robust prosocial abilities beyond those previously documented. These findings contribute critical information about the typical development of prosocial behaviors in the largest and most racially and socioeconomically diverse sample of infants to date.
