    Get PDF
    This research is intended to conduct a legal comparison between Indonesian law with French and German law regarding match fixing in football with the aim of studying the options whether the law in the two countries can be applied to our national law for the improvement of national law. This research is conducted with the type of normative legal research using secondary data in the form of primary legal materials and secondary legal materials obtained through literature study. The approach to conducting this norm comparison is included in the micro approach whose focus is the regulation of law. The method used in this research is the functional method, which means that in this research what is compared is the law as it functions and applies in a particular society in a particular place. The result and conclusion of this research find that Indonesia does not have specific regulations regarding match fixing in sports, especially football and Indonesia should be able to make “legal reforms” by regulating the application of the concept of private sector corruption, elements of prohibited actions such as accepting, giving, and requesting gifts, rewards, certain benefits for themselves or other parties that can affect the outcome or process of the match, as well as regulating more severe sanctions related to fines considering the motivation for committing match fixing crimes is financial gain with reference to French and German criminal law

    Enhancing Biochemistry Assessment Quality in Medical Education Through Item Response Theory (IRT)

    Background In medical education, particularly in biochemistry, crafting high-quality assessment questions is a primary challenge. Each item necessitates thorough evaluation, and precise identification of student abilities is crucial for maximally reflecting learning achievement. Objective This study aims to enhance assessment quality in biochemistry medical education by implementing Item Response Theory (IRT). This approach addresses Classical Test Theory (CTT) limitations. Recognizing the critical role of question quality in the learning process, the study investigates how IRT can more holistically and equitably assess student abilities. It includes a comparative analysis of student scores before and after IRT implementation. Methods Employing a mixed-method research approach, this study combines comparative quantitative analysis with qualitative ICC curve analysis in a pre-post experimental design. It focuses on biochemistry exam data from medical students (n = 89). IRT is used to measure the probability of student responses to questions, using parameters such as discrimination, difficulty level, and guessing probability. Jamovi software supports this analysis by accelerating computational processes. Results Significant improvements were observed in both question quality and student scores. Prior to IRT implementation, the average initial exam score was 56.1, which increased to 74.1 in the subsequent exam. The IRT evaluation indicated that the exam questions achieved a more effective differentiation between students of varying abilities. This improvement was evident from the increased person reliability and through Wright Map visualizations, which helped identify highly difficult questions via the Item Characteristic Curve (ICC). Conclusion The study advocates for integrating IRT as a standard method in biochemistry medical assessments. It highlights the necessity of assessments that are sensitive to individual student capabilities, providing more precise feedback for enhancing the quality of learning. These findings are crucial for evolving evaluation methodologies and advancing medical education standards

    Genomic profile of Parkinson's disease in Asians

    Get PDF
    Parkinson's Disease (PD) has witnessed an alarming rise in prevalence, highlighting the suboptimal nature of early diagnostic and therapeutic strategies. To address this issue, genetic testing has emerged as a potential avenue. In this comprehensive review, we have meticulously summarized the variants associated with PD in Asian populations. Our review reveals that these variants exert their influence on diverse biological pathways, encompassing the autophagy-lysosome pathway, cholesterol metabolism, circadian rhythm regulation, immune system response, and synaptic function. Conventionally, PD has been linked to other diseases; however, our findings shed light on a shared genetic susceptibility among these conditions, implying an underlying pathophysiological mechanism that unifies them. Moreover, it is noteworthy that these PD-associated variants can significantly impact drug responses during therapeutic interventions. This review not only provides a consolidated overview of the genetic variants associated with PD in Asian populations but also contributes novel insights into the intricate relationships between PD and other diseases by elucidating shared genetic components. These findings underscore the importance of personalized approaches in diagnosing and treating PD based on individual genetic profiles to optimize patient outcomes

    The purpose of this study was to investigate the influence of positive aand negative emotions on investment decisions during the Covid-19 pandemic, as well as to test risk tolerance as a intervening variable between basic emotions and investment decisions. This study uses endogenous variables, namely investment decisions and exogenous variables, namely positive and negative emotions including anger, sadness, hope, happiness, and fear. As well as the intervening variable, namely financial risk tolerance. Data collection was carried out by distributing questionnaires to 180 young investors in Surabaya, Indonesia. The questionnaire uses a 5-point Likert scale. Hypothesis testing uses a structural equation model. The results of the study indicate that there is a significant impact of positive emotions on investment decision-making. The association in question is mediated by financial risk tolerance. The regulation of the relationship between negative emotions and investment decisions by financial risk tolerance remains unclear. Furthermore, the impact of negative emotions on investment decisions appears to be insignificant. Practical implications of this research help young investors of generation z to manage their emotions, especially in the era of Covid-19. This is because emotions can affect their investment decision making. The originality of this research is a unique study of the positive and negative emotions associated with the investment decisions of young investors in the Covid-19 era.

    The impact of nanoplastics on the environment and human health is a growing concern. Due to their small size and chemical properties, nanoplastics pose a higher risk than microplastics. Membrane filtration processes have been identified as effective for nanoplastic removal, but integration with other remediation techniques is necessary, except for membrane bioreactors. Membrane bioreactors show promise in handling nanoplastics due to their bioprocessing capability. This review critically evaluates current research on membrane processes and their integration for nanoplastic removal. It discusses the principles and challenges associated with these technologies. The study provides new strategies to expand the industrial-scale application of membrane processes for the treatment of nanoplastics. This review highlights the importance of addressing nanoplastic pollution and presents avenues for future research and implementation
