Authors: Nasution Muhammad Idris , Syafruddin Syam Syafruddin
Published: July 2024

Cancellation or fasakh of marriage due to religious conversion is not included in the family cancellation of marriage as part of the competence of the Religious Courts, but it is implemented through divorce institutions, giving rise to disparities in decisions between fasakh, talak bain and talak raj'i permission. The author found two Supreme Court decisions that canceled and corrected the decisions of two High Religious Courts that canceled a marriage because it was proven that one of the husband and wife had a religious conversion. The Supreme Court is of the opinion that the permit to impose talak raj'i is more appropriate on the grounds according to the posita and petitum of the petition. The Supreme Court consistently applies this rule in its two decisions, but the author finds eleven decisions of the Religious Courts in the following years still impose fasakh if it is proven that one of the married couples is an apostate (out of Islam), even though it is not used as an excuse for divorce and is not requested by the party in the petitum. In this article, the author will examine the legal considerations of eleven Religious Court decisions using an explanatory method and presented qualitatively. The results of the author's study show that the judge's consideration is influenced by the judge's perception of the application of the ultra petita principle with the principle of ex aequo et bono, the judge's perception of the adjudication of fiqh schools and the judge's perception of the independence of judges and compliance with jurisdiction.

As a result of the discussion, it was concluded that there are no specific rules that provide for legal protection of copyright holders when persona claims are false, and that there is a problem of norm vacuum and that there are no rules. Fix implying issues. Under Islamic law, copyright owners must obtain legal protection in order to generate profits consistent with the purposes of maqasid as-syari'ah, including: preservation of the soul (Hifz al-nafs), preservation of reason (Hifz al-'aql), preservation of property (Hifz al-mal).
Inadequacies of Sommerfeld’s Front Velocity Definition
Authors: Kühn Steffen
Published: July 2024

Current practice defines the front velocity of a signal as the limit of the phase velocity for infinitely high frequency. However, the present article provides evidence that the propagation velocities of signal fronts for input signals of nonzero temporal duration result from the phase velocities in the low-frequency range. In conclusion, although the impulse response propagates at the phase velocity for infinitely high frequency, this is shown not to be true for the step response. The article further clarifies that the front or information velocity should be defined as the fastest phase velocity of a transmission medium.

Published: July 2024

Background: Depression is a significant mental health illness characterized by feelings of grief, disinterest, low self-esteem, altered sleep patterns, and decreased appetite. The high prevalence of antepartum depression (68.2 %) has pointed toward the importance of improving health services for mental health. Regardless of the alarming prevalence, it’s still neglected in developing countries. Hence the study aimed to determine the factors associated with antepartum depression among women in a tertiary care hospital in Karachi.
Methodology: Analytical Cross-sectional study was conducted over a period of one year, on 134 women for antepartum depression. Edinburgh Postpartum Depression Scale and a closed-ended questionnaire were used. The Chi-square test was used to determine if a relationship was significant at P value < 0.05. The bivariate and multivariate logistic regression analyses were performed to identify predictors of antepartum depression.
Results: The study found a high prevalence of antepartum depression, affecting 70% of women. Severe depression was reported in 64.06% of antepartum women. A significant association was observed between antepartum depression and family abuse (P-value; 0.011*).
Conclusion: Our study reported high burden of depression, where income and education level of the husband were associated with antepartum depression. Important social factors such as violence and husband abuse, family abuse, and lack of decision-making power were also significant. This high burden of depression demands an urgent need for intervention targeted at raising mental health awareness of women, empowering them for making decisions for their health and well-being.

Published: July 2024

The obligatory will regulated in Article 209 of the Compilation of Islamic Law is only for adoptive parents and adopted children, there is no obligatory will for heirs of different religions. On the other hand, there is a need for legal provisions that present a solution to provide part of the inheritance to heirs who do not receive inheritance due to religious differences. The purpose of this research is to analyze the important obligatory will in terms of its necessity, as well as a study of the obligatory will in terms of the procedure or implementation of the obligatory will itself in resolving disputes in court with legal considerations that are certain, fair and beneficial. The research method uses a qualitative method with a normative juridical approach. Primary data was obtained from regulations, laws, verdict numbers: 368 K/AG/1995, 51 K/AG/1999, 16 K/AG/2010, 721 K/AG/2015, 218 K/AG/2016 and 331 K/AG/2018. Supreme Court Decision No. 331 K/AG/2018 as well as the Compilation of Islamic Law (KHI) article 209 and regulations governing mandatory wills, secondary, tertiary data obtained from library studies, books, documents, journals and so on that have the same relevance to this research. The analysis process uses a legal logic approach, which analyzes the norms and laws or regulations that apply in depth, radically, systematically, and logically. The results of this study concluded that the dynamics of religious court decisions regarding compulsory bequests for heirs of different religions vary greatly, some are granted and some are rejected, the consideration depends on the sitting of the case that is disputed in the religious court, while the granting of compulsory bequests for heirs of different religions refers to the opinion who allows it as long as it is a will and the different religion in question is not kafir dzimmi. The effect of this decision becomes jurisprudence as part of the source of law for judges at levels below the Supreme Court. The contribution of the religious court's decision on this matter is that it can become a permanent jurisprudence so that it is proposed as a new article in KHI to fill in the missing article regarding mandatory wills for heirs of different religions.

Published: July 2024

The article examines the factors influencing the duration of registered unemployment and the probability of employment after it. Such an analysis is important for determining the target direction of active and passive state labor market policies and transitioning to evidence-based policy implementation. The empirical basis of the study consists of impersonal microdata on the characteristics of citizens officially considered as unemployed and the services they received in 2017—2019. We assess the probability of exit and the duration of staying in registered unemployment using survival analysis methods (Cox proportional hazards models and Kaplan—Meier survival function). Our results showed that higher education together with high qualification level of women and belonging to the group of skilled workers of men, increased the likelihood of transition from registered unemployment to permanent work. Women with low education and qualification levels living in rural areas move faster into temporary employment. The research findings are relevant for developing policies aimed at increasing the efficiency of employment centers especially those providing services toward rural unemployed.

Published: July 2024

In modern telecommunications and computer networks, efficient and reliable information collection is essential for effective decision-making and control task resolution. Current methods, such as periodic data transmission, event-driven data collection, and on-demand requests, have distinct advantages and limitations. The object of the paper: The study focuses on developing a comprehensive model to optimize information collection processes in network environments. Subject of the paper: This paper investigates various information collection methods, including periodic data transmission, event-driven data collection, and on-demand requests, and evaluates their efficiency under different network conditions. This study proposes a flexible and accurate model that can optimize information support technologies for network control tasks. The key tasks include 1. Developing a probabilistic-time graph model to evaluate the efficiency of different information collection methods. 2. Analyzing model performance through mathematical relationships and simulations. 3. Comparing the proposed model with existing methodologies. Results. The proposed model demonstrated significant variations in the efficiency of the information collection methods. Periodic data transmission increased network load, while event-driven data collection was more responsive but could miss infrequent changes. On-demand requests balanced timely data needs with resource constraints but faced delays due to packet loss. The probabilistic time graph effectively captured these dynamics, providing a detailed understanding of the trade-offs. Conclusions. This study developed a flexible and accurate model for optimizing information support technologies during network control tasks. The model's adaptability to varying network conditions has significant practical implications for improving network efficiency and performance. Future research should explore the integration of machine learning techniques and extend the model to more complex network environments.

The article's subject is models and methods for ranking candidates for an IT project team with uncertainty regarding competencies and requirements. The aim is to improve the quality of the IT project team by creating and applying models and a method for formalizing the task of multi-criteria ranking of candidates for the team, taking into account the uncertainty of the initial information. Tasks: to analyze the relevance of the task of creating models and methods for ranking candidates for the IT project team under conditions of uncertainty; to develop a method for multi-criteria ranking of candidates for the IT project team in a fuzzy formulation; and to solve an example of the task of multi-criteria ranking of applicants for further formation of the IT project team. The methods used are the analytic hierarchy process, the line method, and the fuzzy arithmetic method. The following results have been obtained. A method of multi-criteria ranking of candidates for an IT project team has been developed, which differs from existing methods by using fuzzy numbers to set the preferences of candidates and assess the generalized competence of each candidate based on comparisons with the reference competence, which improves the ability to evaluate candidates. This method can be used in the first stage of creating an IT project team when candidates for the team are ranked. The task of selecting candidates for further formation of the IT project team has been solved. Conclusions. The scientific novelty of the method of multi-criteria ranking of candidates for the project team is that, unlike existing methods, it uses fuzzy ideas about the preferences of candidates when assessing the generalised competence of each candidate based on comparisons with the reference competence, which allows to improve the ability to evaluate candidates. This article considers an example of using the proposed method to solve the problem of selecting candidates to further solve the problem of forming an IT project team under fuzzy evaluation.

Utilizing advanced methods such as transient elastography is crucial for achieving a precise diagnosis, which depends on a combination of clinical judgment, imaging tests, and histological examination. Various therapeutic approaches may be used based on the harshness of the patients state, including liver transplantation, pharmacotherapy, endoscopic interventions, and modifications in lifestyle. The prediction of the illness is contingent upon the severity of the cirrhosis and the resulting complications. Severe cirrhosis is correlated with an increased likelihood of death, in addition to the development of hepatocellular cancer. Healthcare professionals must collaborate across several disciplines to provide optimal care to their patients.

Understanding the prevalence, demographics, and satisfaction levels associated with flexible study modes (e.g. part-time studies, distance learning, and online lectures) offers insight into the evolving landscape of higher education, particularly in the context of rapid technological advancements and global challenges such as the COVID-19 pandemic. Exploring various characteristics of higher education institutions offers valuable insights into the diversity and dynamics of educational landscapes. This chapter takes both, flexible study modes and institutional characteristics, into account. Amongst others, it is found that while national higher education systems exhibit various forms of study flexibility to differing extent, while certain socio-demographic and study-related preferences for flexible study modes hold true across countries. Further on, certain institutional types (such as non-universities, institutions with higher imbalance in the student-to-academic staff ratios, less research-intensive, subject-specialised institutions) emerge as prominent providers of flexible study modes.
