Legal framework for health policy to reduce the level of substance abuse in the United States

The purpose of this study was to identify and legally assess the key legal instruments and strategies employed in the United States of America to combat substance abuse and their impact on the development of national health policy in this area. The study used quantitative and qualitative methods of analysis, including the processing of statistical data on the financing of addiction prevention and treatment programmes, analysis of federal and regional legislative acts, and comparative analysis of the policies of different states on the regulation of psychoactive substances. The key findings showed a significant evolution of the legal approach to the problem of substance abuse. The study revealed a gradual shift from a purely punitive approach to a balanced strategy that combines elements of prevention, treatment, and harm reduction. Furthermore, the analysis of funding showed a 35% increase in federal support for prevention programmes between 2018 and 2022, which led to improved access to healthcare for drug users and the development of recovery programmes. The results of a comparative analysis of state policies on the regulation of psychoactive substances showed a considerable difference in approaches, specifically regarding the legalisation of marijuana, which creates legal and regulatory challenges due to contradictions between federal and local laws. Specifically, in states where marijuana is legalised for medical or recreational use, the level of trafficking offences has decreased, but questions arise concerning the regulation of cultivation and distribution. It was also found that the introduction of telemedicine has significantly increased the effectiveness of drug treatment in a pandemic, allowing more patients to be reached, but this approach needs further improvement in the field of regulation and control. The findings of the study point to the need for closer integration of prevention, healthcare, and legal measures at all levels of government, unification of legislation on the regulation of psychoactive substances at the federal and state levels, as well as decriminalisation of drugs for personal use, which can reduce the level of criminalisation of society and contribute to a more effective fight against substance abuse

Influence of Micro, Small & Medium Enterprises Taxpayer Compliance Factors in Bandung

The Indonesian State Revenue and Expenditure Budget (APBN) is primarily funded by taxes. There are 65.5 million micro, small, and medium-sized enterprises (MSMEs) in Indonesia, making them a sector with a significant potential to assist with tax payments. In order for MSMEs to actively participate in taxation, the government continues to provide various facilities. The Indonesian tax self-assessment system, on the other hand, grants the taxpayer authority to determine the amount of tax owed, which necessitates the taxpayer's awareness and complete compliance. As a result, research was conducted on the factors that influence MSME taxpayer compliance, using tax knowledge, taxpayer awareness, and taxpayer motivation as the variables. Using a purposive sampling strategy, this study selected 100 MSMEs from Bandung with diverse industrial backgrounds and characteristics as the sample population. This study employs quantitative and explanatory analysis methods, as well as a questionnaire as the research medium. PLS-SEM was also used for analysis, and two assessments, the measurement model (validity) and the structural model assessment, were performed. This study found that taxpayer awareness has no significant impact on tax compliance, while tax literacy and taxpayer motivation have a significant impact. Accurate tax reporting and payment are supported by solid literacy. Because taxpayers are unaware of government losses, their awareness has less of an impact. Compliance is largely driven by internal and external motivation

The Impact of the National Export Strategy on the Plastics and Packaging Industry in Malawi

ABSTRACT: Export-led industrialization is crucial for economic growth, emphasizing the shift from primary production to manufacturing. Malawi aims for industrialization through its National Export Strategy (NES), focusing on oilseed and sugarcane products and manufacturing. However, research gaps exist on export promotion programs’ impact, especially in less developed countries like Malawi and specific sectors like plastics and packaging. A mixed-method approach was employed, combining qualitative and quantitative methods for robust analysis. All 13 firms in Malawi’s plastics and packaging industry were surveyed in Blantyre and Lilongwe to assess the impact of the National Export Strategy (NES). A questionnaire with 37 questions across six sections, adapted from prior research, was used to gather comprehensive data on various aspects such as employment, production, and investment. Ethical clearance was obtained, and completed questionnaires underwent thorough review before data analysis. Results are presented in subsequent sections. The impact of Malawi’s National Export Strategy (NES) on its plastics and packaging industry highlights vital challenges. Employment suffers from a lack of skilled labor, stemming from a mismatch with training institutions. Firms struggle with limited access to finance and high borrowing costs, hindering investment. High taxes and duties hamper export competitiveness, while unreliable energy supply increases operational costs. Additionally, transportation expenses impede raw material imports, exports, and local distribution. These findings underscore the need to address skill mismatches, enhance financial access, reduce trade barriers, and improve infrastructure to bolster the industry’s resilience and competitiveness under the NES. Policy implications include collaborating with financial institutions to enhance access to grants and affordable credit, imposing higher import taxes on finished products to protect local producers, improving energy supply, enhancing transportation infrastructure, introducing incentives for investment in support services, raising awareness of NES benefits, and establishing industry-specific meetings to address sector-specific issues. These measures aim to bolster the plastics and packaging industry’s competitiveness and support its growth under the NES.

An Integrated Quantitative Method of Risk Analysis and Decision Making for Safety Manipulation of a Forest Firefighting Aircraft by Using Physical Models of Multi-Hazard Factors

Although firefighting aircrafts are effective for fighting forest fires, they are affected by a variety of risks related to forest fires during flight operations such as thermal radiation, temperature rise, decrease in air density, and changes in updraft aerodynamics. However, quantifying these influences poses a challenge. Our research reveals that safety standards predominantly hinge on technical indicators like flight height, speed, and angle of attack, which makes it possible to quantify the above effects. A general method framework for analysing firefighting flight safety criteria was constructed in this thesis. Using relevant physical models, such as heat radiation, temperature, air density, and updraft in a forest fire environment, safety criteria with an analytical form were established. The corresponding safety constraints of each criterion were calculated quantitatively, and the most stringent constraint was determined based on multiple factors to obtain a comprehensive safety constraint boundary composed of the critical altitude, stall speed, and critical angle of attack. Finally, the effectiveness of the method is verified in a simulation case. The research results show that the constrained boundary calculation method proposed in this study can provide a scientific basis for the formulation of technical specifications for forest aviation fire safety and aviation fire task planning.
