The article discusses piggyback transportation and their role in modern logistics technologies, which make it possible to implement certain elements of the concept of sustainable development of both regional and international economies. The main aspects of the organization of piggyback transportation, their advantages and disadvantages have been studied, the problems of use in the conditions of the Russian Federation have been identified. The lack of experience in their implementation, the insufficient level of interaction between various sectors of the economy were noted as one of the main problems of using piggyback transportation in the formation of logistics chains, as well as the complexity and ambiguity of assessing the effectiveness of their implementation. The paper proposes an approach to assessing the effectiveness of piggyback transportation, based on the use of expert assessment methods, in particular, the Delphi method and the Saati hierarchy analysis method. The features of the implementation of piggyback transportation in the West Siberian region of the Russian Federation are noted.

AbstractThe use of generative design grammars for computational design synthesis has been shown to be successful in many application areas. The development of advanced search and optimization strategies to guide the computational synthesis process is an active research area with great improvements in the last decades. The development of the grammar rules, however, often resembles an art rather than a science. Poor grammars drive the need for problem specific and sophisticated search and optimization algorithms that guide the synthesis process toward valid and optimized designs in a reasonable amount of time. Instead of tuning search algorithms for inferior grammars, this research focuses on designing better grammars to not unnecessarily burden the search process. It presents a grammar rule analysis method to provide a more systematic development process for grammar rules. The goal of the grammar rule analysis method is to improve the quality of the rules and in turn have a major impact on the quality of the designs generated. Four different grammars for automated gearbox synthesis are used as a case study to validate the developed method and show its potential.

Research on Islamic economics experienced rapid development in recent years along with the development of Islamic economics as a branch of science throughout the world, especially in Muslim countries. This paper aims at mapping and observing the trend of Islamic economic studies listed on SINTA, the official Indonesian indexing website. The sampling data for this study is 114 published papers obtained from the website. The data are analyzed using quantitative descriptive with bibliometric analysis method. This study found that most papers are published by “Al-Iqtishad: Jurnal Ilmu Ekonomi Syariah”, owned by Syarif Hidayatullah State Islamic University. The qualitative approach is most used by research samples in this study with 74 papers (64.91%), while quantitative is only used by 40 papers (35.08%). It also found that Islamic economic research in Indonesia is dominated by Islamic bank topics with several general bank keywords, such as efficiency, profitability, liquidity, and Non-Performing Financing (NPF). This study suggested that further researchers conduct more studies on Islamic or Sharia values implemented within Islamic banks since it is the main difference between Islamic and conventional banks. Further studies can also observe broader problems like poverty and how the Islamic economy has overcome this issue==================================================================================================== ABSTRAK – Pemetaan Tren Kajian Ekonomi Islam pada Pengindeks SINTA: Suatu Analisis Bibliometrik. Penelitian di bidang ekonomi Islam mengalami perkembangan yang cukup signifikan beberapa tahun terakhir bersamaan dengan perkembangan ekonomi Islam sebagai salah satu cabang ilmu pengetahuan, terutama di negara-negara dengan mayoritas penduduknya adalah Muslim. Artikel ini bertujuan untuk melakukan pemetaan dan melihat tren publikasi pada artikel penelitian ekonomi Islam yang terindeks SINTA, website pengideks resmi Indonesia. Sebanyak 114 artikel diperoleh dari SINTA untuk dijadikan sebagai sampel penelitian. Metode yang digunakan adalah deskriptif kuantitatif dengan analisis bibliometrik. Penelitian ini menemukan bahwa mayoritas paper dipublikasikan oleh “Al-Iqtishad: Jurnal Ilmu Ekonomi Syariah” dari UIN Syarif Hidayatullah Jakarta. Pendekatan kualitatif digunakan oleh 74 sampel artikel (64.91%), sementara pendekatan kuantitatif digunakan oleh 40 artikel (35.08%). Studi ini juga menemukan bahwa artikel kajian ekonomi Islam di Indonesia masih didominasi oleh penelitian terkait bank syariah dengan beberapa kata kunci, diantaranya: efisiensi, profitabilitas, likuiditas, dan Non-Performing Financing (NPF). Penelitian ini merekomendasikan kepada para peneliti di bidang ekonomi Islam untuk melakukan kajian lebih mendalam pada nilai-nilai Syariah yang diimplementasikan di bank Syariah karena hal tersebut merupakan perbedaan mendasar antara bank Syariah dan bank konvensional.

Введение. Реализация современной модели образования требует от педагогических работников владения определенными навыками научно-исследовательской работы и использования научно обоснованных форм и методов в своей профессиональной деятельности. Опора на науку должна позволить достичь требуемого качества образования и тем самым обеспечить выполнение социального и государственного заказа перед системой образования. В настоящее время существуют серьезные проблемы, касающиеся воспроизводимости процесса и результатов педагогических исследований. В этой связи при исполнении требования достижения качества образования педагоги сталкиваются с серьезной проблемой, а именно с кризисом воспроизводимости. Кризис воспроизводимости – это серьезный методологический кризис, суть которого заключается в невозможности повторить результаты исследований, которые были ранее опубликованы, или невозможность повторить само исследование (по техническим и иным причинам). Чаще всего это обусловлено отсутствием или недостаточной представленностью следующих элементов педагогических исследований: наличие эксперимента, четкое описание планирования и хода эксперимента, проверяемые данные – когда непонятно, что, каким образом и в каких условиях воспроизводить. Цель – научно обосновать целесообразность экстраполяции метода метаанализа из доказательной медицины в педагогические исследования в качестве инструмента для повышения воспроизводимости как экспериментов, так и получаемых результатов в педагогических исследованиях. Материал и методы. Основой методологии исследования стали следующие методы: изучение и анализ литературы, аналитического обобщения, прогнозирования, абстрагирования, аналогии, измерения, синтезирование данных, обобщение, моделирование, аналогии, статистической обработки полученной информации. После того, как были рассмотрены основные причины, вызывающие кризис воспроизводимости в науке, в качестве средства минимизации негативного влияния кризиса воспроизводимости обосновано применение метода метаанализа в педагогических исследованиях. Результаты и обсуждение. Проанализирована актуальная литература по проблематике исследования. Изучены и обобщены сущностные черты и причины кризиса воспроизводимости в педагогических исследованиях. Установлено, что кризис воспроизводимости носит междисциплинарный характер. Актуализирована проблема поиска средств минимизации негативного влияния кризиса воспроизводимости на развитие педагогических исследований. В качестве такого средства рассмотрен метаанализ и выдвинуто предположение о целесообразности его экстраполяции из медицины в педагогические исследования. Проанализированы теоретические и практические аспекты применения метода метаанализа. Выведены определения понятий «метаанализ» и «систематический обзор». Установлено, что метаанализ пересекается и частично включает в себя элементы таких методов и технологий, как контент-анализ, прикладная наукометрия, блокчейн. Рассмотрены организационные и содержательные особенности метаанализа, позволяющие применять данный метод для оценки качества педагогических исследований. Предложен контурный план метаанализа научных публикаций, отражающих результаты педагогических исследований. Выдвинут ряд дискуссионных положений, которые могли бы стать основанием для дальнейших исследований. Намечен путь комплексного изучения инструментов минимизации негативного влияния кризиса воспроизводимости в педагогических науках. Заключение. Обосновано применение метаанализа в качестве эффективного инструмента: 1) оценки качества педагогических исследований; 2) планирования и организации эксперимента; 3) представления результатов эмпирических исследований в педагогике. Introduction. The implementation of the modern model of education requires teaching staff to possess certain skills in research work and to use scientifically grounded forms and methods in their professional activities. It seems that reliance on science should make it possible to achieve the required quality of education and thereby ensure the fulfillment of the social and state order for the education system. In particular, it is necessary to fix the fact that in empirical research used in science, there are, today, serious problems regarding the reproducibility of the process and the results of pedagogical research. In this regard, in fulfilling the requirement to achieve the quality of education, which is verified, first of all, by empirical research, teachers are faced with a serious problem, namely, with a crisis of reproducibility. The reproducibility crisis is a serious methodological crisis, the essence of which is the impossibility of repeating the results of studies that were previously published or the impossibility of repeating the study itself (for technical and other reasons). Most often, this is due to the absence or insufficient representation of the following elements of pedagogical research: the presence of an experiment, a clear description of the planning and course of the experiment, verifiable data – when it is not clear what, how and in what conditions to reproduce. The goal is to scientifically substantiate the feasibility of extrapolating the meta-analysis method from evidencebased medicine to pedagogical research as a tool to increase the reproducibility of both experiments and the results obtained in pedagogical research. Material and methods. The research methodology is based on the following methods: study and analysis of literature, analytical generalization, forecasting, abstraction, analogy, measurement, data synthesis, generalization, modeling, analogy, statistical processing of the information received. After the main reasons causing the crisis of reproducibility in science were considered, the use of the meta-analysis method in pedagogical research was substantiated as a means of minimizing the negative impact of the crisis of reproducibility. Results and discussion. The current literature on the research problem is analyzed from different positions. The essential features and causes of the crisis of reproducibility in pedagogical research have been studied and generalized. It was found that the crisis of reproducibility is interdisciplinary in nature. The problem of finding means to minimize the negative impact of the crisis of reproducibility on the development of pedagogical research is actualized. As such a tool, a meta-analysis is considered and an assumption is made about the advisability of extrapolating the method of meta-analysis from medicine to pedagogical research. The theoretical and practical aspects of the application of the meta-analysis method are considered. The definitions of the concepts of meta-analysis and a systematic review are derived. It was found that meta-analysis intersects and partially includes elements of such methods and technologies as content analysis, applied scientometrics, blockchain. The organizational and substantive features of the meta-analysis are considered, which make it possible to apply this method to assess the quality of pedagogical research. As a practical justification for the applicability of the method, a contour plan for the meta-analysis of scientific publications reflecting the results of pedagogical research is proposed. A number of controversial provisions that could become the basis for further research is put forward. A way is outlined for a comprehensive study of tools to minimize the negative impact of the crisis of reproducibility in pedagogical sciences. Conclusion. The has been substantiated the use of meta-analysis as an effective tool for: 1) assessing the quality of pedagogical research; 2) planning and organizing the experiment; 3) presentation of the results of empirical research in pedagogy.

The low level of financial inclusion for the poor becomes a time bomb amid Islamic finance growth as an alternative and way of life, particularly for those who believe in the application of Islamic tenets in finance. Further, the evolving of fully-fledged Islamic Financial Non-Bank Institutions, particularly Islamic Microfinance Financial Institutions (IMFIs) are one of the myriad ways in alleviating poverty. Indonesia, with the highest number of the Muslim population in the world, can reduce the poverty percentage by using Islamic social funds, namely infaq, zakah, shadaqoh and waqf. This study sheds light on how to optimise the Islamic social fund benefit for improving the poor’s quality of life; both by injecting money to provide them with a business skill and to feed people them who are poor. We use meta-analysis method to recap different findings related to maximise the usage of Islamic social funds across a different point of view, hence a fit mechanism is found to be applied. It found that Islamic social funds can be used to sustain the fund whilst enabling the poor for generating income by integrating the fund with economics activities.

Understanding the driving forces of land use/cover change (LUCC) is a requisite to mitigate and manage effects and consequences of LUCC. This study aims to analyze drivers of LUCC in New England, USA. It combines meta-study, GIS, and machine learning to identify the important factors of LUCC in the area. Firstly, we conducted a meta-study of the research on LUCC in the New England area and specifically focused on the driving forces analysis. The meta-analysis revealed that the LUCC studies in the research area were highly related with many other research topics, and population and economic factors were the most mentioned drivers of the LUCC. The drivers of LUCC in this study area for the past several decades were relatively well analyzed. However, the study of the main driving forces of recent LUCC is lacking. Then, the determinants of LUCC for the recent years were quantitatively assessed using the random forests (RF) model along with geospatial data processing. Two planning regions in Connecticut and one planning region in Massachusetts were selected to serve as the case study areas. Investigated variables included environmental and biophysical variables, location measures of infrastructure and existing land use, political variables, and demographic and social variables. These drivers were examined for their relations with LUCC processes. Their importance as driving forces was ranked by the RF method. The results show both consistency and inconsistency between the meta-analysis and the RF method. We found that this mixed method can enhance our understanding of driving forces of LUCC and improve the selection quality of important drivers for modeling LUCC. With more solid information, better land management advices for sustainable development may also be provided.
