Published: January 2024

To address the increasing cases of sexual violence in Indonesia and globally, there is a need to develop comprehensive strategies and initiatives. One approach is to enhance character development within the university environment, specifically through the implementation of a robust Healthy Campus Program. This program aims to instill national character values, focusing on education and higher education settings. The research employs qualitative methods, utilizing both secondary and primary sources, to shed light on the gravity of the issue and potential solutions. This holistic approach addresses not only the intellectual but also the spiritual aspects of individuals, emphasizing the importance of moral values and ethical conduct. It is through education that the foundation for preventing sexual violence can be laid. In addition to formal education, a Healthy Campus Program necessitates active involvement from the entire academic community. This collaborative effort is underscored by the guidelines outlined in Permendikbudristek No. 30 of 2021 concerning Crimes of Sexual Violence. The responsibility to foster a secure environment extends to all stakeholders within the university setting. By integrating character development initiatives and implementing a Healthy Campus Program, universities can contribute significantly to the prevention of sexual violence. This multifaceted approach aims not only to raise awareness but also to cultivate a culture of respect, empathy, and accountability. Through these collective efforts, it is envisioned that the number of sexual violence cases will decrease, creating a safer and more nurturing environment within and beyond university campuses.

The Difference Method Makes: Judicial Restraint and Judicial Creativity in Rana Nahid v Sahidul Chisti
Authors: Mandal Saptarshi
Published: January 2024

Restraint and creativity are both necessary judicial attitudes. But when should judges exercise restraint in adjudication and when, creativity? This is the question posed by the Supreme Court’s 2020 split verdict in the case of Rana Nahid v Sahidul Chisti, which required the Court to decide whether Family Courts had jurisdiction over maintenance claims under the Muslim Women (Protection of Rights on Divorce) Act, 1986. By contrasting the two approaches taken by the judges to statutory interpretation in this case, the note argues that while judges should refrain from arbitrary rule making, creativity must be viewed as duty when it can fill a gap in the law or prevent an unreasonable outcome and is in furtherance of pre-existing legal principles.
Locating the 'Nanny' in Legal Theory
Authors: Agarwal Akshat
Published: January 2024

Paid domestic workers pose a challenge to legal theorists since they occupy the unique intersection of the market and the home. While being paid for the ‘care’ they provide, their work is characterised by a high degree of informality and is usually also considered emotive. I use India as a case study to show how attempts to include paid domestic workers within formal labour law protections have been consistently unsuccessful, which demonstrates the unique nature of paid domestic work. At the same time, academic arguments for the inclusion of such workers in family law frameworks raise several practical concerns and do not respond to the demands of domestic worker organising. This presents both difficult questions and unsatisfying answers. I suggest that instead of looking for all-encompassing legal theories, the law should embrace the legal ambivalence of paid domestic workers and create a menu of options that address their specific vulnerabilities.

Published: January 2024

The aim of this study was to investigate the acute effects of different myofascial release exercise durations on heart rate, saturation and blood pressure values in young archers. For this purpose, a total of 12 young athletes aged 16-18 years were included in the study. Myofascial release exercises using foam rollers were applied to the participants on different days. The inclusion criteria were determined as being healthy, not having a chronic disease, not having any medication used continuously and being interested in active archery sport. Control (T1), experimental (T2), and experimental (T3) foam rollers for 30 seconds and 60 seconds, respectively, were applied to the young archers on different days and heart rate, SpO2 levels and blood pressure values were measured after the applications. SPSS 22.0 programme was used to analyse the data obtained. One-way analysis of variance and LSD tests for repeated measures were performed to determine the difference between the groups of the application results. As a result of the analysis, no statistical significance was found in the saturation values, diastolic and systolic blood pressure values of the groups (p>0.05). There was statistical significance between T1 and T3 groups in the heart rate in favour of T3 (p<0.05). Myofascial release exercises affected the heart rate in terms of the parameters evaluated in long-term applications. It can be said that this change is a result of the energy and effort expended.

Published: January 2024

Antimicrobial resistance (AMR) is a global public health challenge. AMR is the ability of a microorganism to resist antimicrobial attack, which in turn prevents successful treatment of an infection. Massive antibiotic therapy has led to an increase in the antibiotic resistance of pathogens of infectious diseases. The problem of antibiotic resistance is especially acute in the treatment of nosocomial infections. Nosocomial infections also called “hospital-acquired infections”, are infections acquired during hospital care which are not present or incubating at admission. Infections occurring more than 48 hours after admission are usually considered nosocomial. The main reason for the prolonged hospitalization of patients infected with COVID-19 is to internal infections of the hospital and complications caused by their influence. it was important to determine the bacterial spectrum of etiological agents of nosocomial infections in patients infected with COVID-19 and the profile of antibiotic resistance. The research materials were collected at the different hospital resuscitations from patients undergoing treatment for a long time and who were resistant to antibiotics. As the resalts showed the highest resistance to amp/sulbactam, Aztreonam, ampicillin, meropenem, moxifloxacin, cefepime, ceftazidime, cefotaxime, ciprofloxacin Levofloxacin, amox/clavulanate, norfloxacin, pip/tazobactam, ceftriaxone was detected in 100 %, resistance to cefoxitin, trim/sulfa and amikacin in 90%, resistance to tobramycin  in 80%, and the relatively low resistance was detected to gentamycin  in 20 %.

Scenario of Zakah Management in Bangladesh: A Critical Analysis
Authors: Hosain Mohammad Loqman
Published: January 2024

The aim of the study is to describe and analyze the real scenario of zakah management in Bangladesh. Zakah is an important tool to eradicate poverty in the country and it can play a vital role in alleviating unemployment too. About 91.04% of the total population of the country is Muslim (Population and Housing Census, 2022, p. 8). A good number of Muslims are capable of paying zakah annually. However, the zakah management system in urban or rural areas is poor. And the capable people on whom zakah is compulsory are not so positive about distributing zakah among (mustahaqqun1) the beneficiary group. Almost, all of the zakah payers are not aware enough to pay zakah in the defined Sariah way. Only a few people legally pay their zakah portion among the eligible class. For this, the actual method of zakah distribution management in Bangladesh is not exercised and executed properly. This is why, the real beneficiary group is not facilitated in a systematic way. This study also tries to focus on the challenges of zakah distribution management in Bangladesh and tries to highlight the effective recommendations for resolving these problems.
