This study aims to systematically identify and review studies on anti-human trafficking campaigns published in peer-reviewed journals to determine the extent to which such campaigns have been critically and rigorously evaluated so as to guide future policies and practice in this area and to identify the main characteristics, problems, and challenges associated with the campaigns in the identified studies. This systematic literature review identified 16 studies that have assessed anti-human trafficking campaigns but found that none of these included outcome, process, or impact evaluations. As identified in our study, anti-human trafficking campaigns tend to rely on advertising techniques to target vulnerable groups and the wider public, with the primary aim of informing and educating. Further, a thematic analysis of the studies identified problems in eight areas that require attention in the future development of anti-human trafficking campaigns: stereotyping, compounding human trafficking with migration, conflating prostitution with human trafficking, sexualization/erotization of women, victimization, role of anti-human trafficking organizations, data shortcomings, and oversimplification of human trafficking. Studies presenting the results of evaluations of social marketing anti-human trafficking campaigns are urgently needed to show which social marketing tools work and to provide an evidence base for future campaigns.

The production of organic products in Bulgaria is constantly growing and the role of this type of production in the development of the agricultural sector cannot be ignored. Bulgarian bio-products have an export orientation and a very small part are traded in the domestic market, which also determines the importance of their competitiveness for the future development of the sector. The purpose of this study is to analyze the competitive position of Bulgarian bio-products. In order to achieve its goal, the research has to solve the following tasks: to analyze the trade with organic products in Bulgaria; to evaluate the potential for development of trade in bio-products in the internal market; to evaluate the competitiveness of Bulgarian organic products.

This article discusses the creation of favorable economic and social conditions for the revival of forgotten traditional handicrafts in Uzbekistan in recent years and the future development of its surviving varieties. In the Soviet era, domestic labor was initially opposed for political and ideological reasons, but later, under the notion of “self-employment,” domestic production was not strongly opposed, but not enough attention was paid to its development.

The role of the Economic Exclusive Zone (EEZ) in the international law of the sea remains a controversial issue two decades after the 1982 United Nations Convention on the Law of the Sea (LOSC) came into force. This chapter examines the evolution of the concept and its juridical nature, and the legal regime applicable to the EEZ. It considers the future development of the EEZ legal regime, exploring the principal controversial features that may influence its course.

Abstract Purpose This study compares prior life cycle assessment (LCA) studies on graphene-based materials (GBMs) with new results from original data on ball milling of few-layer graphene. The analysis thus offers an overview of the current state of knowledge on the environmental sustainability of GBM production. Possible future development pathways and knowledge gaps are identified and explained to provide guidance for the future development of GBMs. Methods Comparable scopes, aggregation levels, and impact assessment methods are used to analyse diverse GBMs with three different functional units for graphene oxide, pristine graphene, and other GBMs with different carbon/oxygen ratios or thickness. The ecoinvent v3.4 cut-off database is used for background data in all models to provide a common basis of comparison. Furthermore, uncertainty calculations are carried out to give insights on the current level of knowledge and to check if GBM production methods can be differentiated. Finally, a sensitivity analysis is performed on the energy inputs with a detailed description of three future scenarios for the European electricity mix. Results and discussion The general analysis of all results highlights three key strategies to improve the environmental sustainability of GBM production. (1) The use of decarbonised energy sources reduces substantially the impacts of GBMs. This benefit is decreased, however, when conservative forecasts of the future European electricity mix are considered. (2) Increased energy efficiency of production is useful mainly for the processes of electrochemical exfoliation and chemical vapour deposition. (3) The principles of green chemistry provide relevant ideas to reduce the impacts of GBMs mainly for the processes of chemical and thermal reduction and for the production of graphene oxide. Furthermore, the analysis of new data on ball milling production reveals that transforming GBM solutions into dry-mass can substantially increase the environmental impacts because of the energy-intensive nature of this conversion. The uncertainty analysis then shows that it is still difficult to differentiate all production methods with the current knowledge on this emerging technology. Conclusions With our current level of knowledge on GBMs, it is clear that more accurate data is needed on different production methods to identify frontrunners. Nevertheless, it seems that unknowns, like the state of future electricity mixes, might not often hinder such comparisons because conservative forecasts bring similar changes on many production options. Additionally, functional properties and toxicity for GBMs will require further attention to improve our confidence in the comparison of production methods in the future.

Purpose of the paper is to determine current issues and prospective directions of the legal technologies’ use for civil aviation safety improvement and future development under modern COVID-2019, post-pandemic challenges and conditions of the new world’s order. By using the dialectical method, the current conceptual framework and issues of the legal technologies as instruments of civil aviation safety improvement have been formulated. The formal-dogmatic method contributed to the development of the authors’ explanation of the current state, issues, challenges, and practical role of the legal technologies for the further improvement of civil aviation safety under the fight against COVID-2019. In the paper modern challenges to the legal technologies’ use for civil aviation safety improvement in pandemic and post-pandemic conditions have been analyzed. Prospects of the legal technologies’ effective implementation for the future civil aviation safety improvement in conditions of pandemic, post-pandemic and new world’s order have been suggested.

This is basically a conceptual paper. It discusses and proposes the need of establishment of the so-called Professional Amil Zakat. The remarkable development of zakat in Muslim countries so far has to be appreciated highly. However, several things must be done, since the achievement is still far below the potential power available.Among many factors that contribute to the development of zakat is that the existence and the role of Amil Zakat. Needless to say, Zakat development will be hopeless without them. However, there is not much attention has been paid to them.The paper argues that the development of Amil Zakat will in turn enhance the successfulness of zakat practices in the future. A way to do so is by establishing the official professional body of Amil Zakat, locally, nationally, or globally. The establishment of such body is believed that it will enhance the professionalism, which finally supports the practices of Zakat. Keywords: Zakat, Amil, Assocation, Professionalism, Future Development
