Low reproducibility rates within life science research undermine cumulative knowledge production and contribute to both delays and costs of therapeutic drug development. An analysis of past studies indicates that the cumulative (total) prevalence of irreproducible preclinical research exceeds 50%, resulting in approximately US$28,000,000,000 (US$28B)/year spent on preclinical research that is not reproducible—in the United States alone. We outline a framework for solutions and a plan for long-term improvements in reproducibility rates that will help to accelerate the discovery of life-saving therapies and cures.

In an increasingly globalised world, economic and cultural imperatives can be seen as two of the most powerful forces shaping human behaviour. This book considers the relationship between economics and culture both as areas of intellectual discourse, and as systems of societal organisation. Adopting a broad definition of culture, it explores the economic dimensions of culture, and the cultural context of economics. The book is built on a foundation of value theory, developing the twin notions of economic and cultural value as underlying principles for integrating the two fields. Ideas of cultural capital and sustainability are discussed, especially as means of analysing the particular problems of cultural heritage, drawing parallels with the treatment of natural capital in ecological economics. The book goes on to discuss the economics of creativity in the production of cultural goods and services; culture in economic development; the cultural industries; and cultural policy.

Modern economics was born in the Marginal revolution and the Keynesian revolution. These revolutions led to the emergence of fundamental concepts and methods in economic theory, which allow the use of differential and integral calculus to describe economic phenomena, effects, and processes. At the present moment the new revolution, which can be called “Memory revolution”, is actually taking place in modern economics. This revolution is intended to “cure amnesia” of modern economic theory, which is caused by the use of differential and integral operators of integer orders. In economics, the description of economic processes should take into account that the behavior of economic agents may depend on the history of previous changes in economy. The main mathematical tool designed to “cure amnesia” in economics is fractional calculus that is a theory of integrals, derivatives, sums, and differences of non-integer orders. This paper contains a brief review of the history of applications of fractional calculus in modern mathematical economics and economic theory. The first stage of the Memory Revolution in economics is associated with the works published in 1966 and 1980 by Clive W. J. Granger, who received the Nobel Memorial Prize in Economic Sciences in 2003. We divide the history of the application of fractional calculus in economics into the following five stages of development (approaches): ARFIMA; fractional Brownian motion; econophysics; deterministic chaos; mathematical economics. The modern stage (mathematical economics) of the Memory revolution is intended to include in the modern economic theory new economic concepts and notions that allow us to take into account the presence of memory in economic processes. The current stage actually absorbs the Granger approach based on ARFIMA models that used only the Granger–Joyeux–Hosking fractional differencing and integrating, which really are the well-known Grunwald–Letnikov fractional differences. The modern stage can also absorb other approaches by formulation of new economic notions, concepts, effects, phenomena, and principles. Some comments on possible future directions for development of the fractional mathematical economics are proposed.

Ecological economics arose in the final decades of the 20th century out of concerns for environmental protection and economic sustainability. It was largely a response to a real or perceived lack of physical and biological underpinnings in neoclassical economics. It was also intended to infuse economics with a moral philosophy, in contrast with the amoral implications of neoclassical models portraying man as a rational, utility-maximizing automaton.

This paper examines the impact of import competition on skill premium and the moderating effect of labor market flexibility on it, using panel data from 30 provinces in China from 2010 to 2019. A dynamic panel threshold model with instrumental variables is employed to address the endogeneity problem and to identify the nonlinear moderating effect of labor market flexibility. The results show the following: (1) Import competition has a promoting effect on skill premium, and this effect declines from eastern to western regions in China. (2) The import competition increases the skill premium through the channels of enhancing regional innovation capacity and promoting industrial upgrading and rationalization. (3) There exists a significant threshold effect in the moderating effect of labor market flexibility. When labor market flexibility surpasses the threshold value of 1.330, the enhancing effect of import competition on the skill premium is alleviated, facilitating labor reallocation and wage adjustment. The integration of labor market flexibility into the globalization–inequality debate extends the existing literature for providing a new understanding of the mechanisms behind the skill premium. The policy implications are that targeted labor market reforms are essential for mitigating wage differentials between skilled and unskilled workers arising from intensified import competition.

В умовах воєнної невизначеності та економічної дестабілізації особливої актуальності набувають питання ефективного фінансового забезпечення діяльності підприємств як ключового чинника їх стійкості та відновлення. Визначальним є пошук нових інструментів мобілізації фінансових ресурсів, що сприятимуть післявоєнному розвитку економіки України. Метою статті є поглиблення теоретичних засад і узагальнення практичних аспектів фінансового забезпечення функціонування та розвитку підприємств України з урахуванням впливу воєнних ризиків і нестабільності зовнішнього середовища. У роботі використано комплексний науковий підхід, що поєднує теоретичне узагальнення, системний, порівняльний, структурно-динамічний аналіз. Дослідження базується на статистичних даних за 2013–2024 рр., що дало змогу простежити трансформації у складі джерел фінансування підприємств та оцінити ефективність механізмів фінансового забезпечення. Теоретичне значення роботи полягає у систематизації наукових підходів до визначення сутності поняття «фінансове забезпечення підприємства» та запропоновано власне трактування даної категорії як інтегрованої системи організаційно-економічних, правових, фінансово-управлінських і контрольно-аналітичних механізмів. У ході дослідження здійснено оцінювання структури джерел фінансування підприємств України; виявлено домінування короткострокових зобов’язань і недостатність власних та довгострокових ресурсів. Охарактеризовано трансформацію механізму фінансового забезпечення в умовах війни; систематизовано джерела фінансування у довоєнний, воєнний і повоєнний періоди. Обґрунтовано стратегічні напрями підвищення ефективності фінансового забезпечення діяльності суб’єктів господарювання. Оригінальність дослідження визначається інтеграцією макро- і мікрорівневих аспектів фінансового забезпечення та розробленням адаптивного механізму, що враховує особливості воєнної економіки. Практична цінність полягає у можливості використання запропонованих рекомендацій при формуванні фінансових стратегій підприємств. Подальші дослідження доцільно зосередити на кількісному моделюванні впливу державних і міжнародних джерел фінансування на економічне відновлення підприємств.

Abstract The research on work-life balance of teachers highlights the significant challenges faced by educators in balancing their professional and personal lives. The study emphasizes the evolving role of teachers, the impact of technology, and the increasing demands placed on them. It also underscores the importance of achieving a healthy work-life balance to reduce stress and improve job satisfaction. This study critically examines research papers and articles related to work-life balance of teachers published between 2014–2024 in the Scopus database. Bibliometric analysis was done with the help of a biblioshiny package of Rstusio and VoS viewer. Out of 554 articles, 112 were located after restricting the search to the English language and publications related to social science, psychology, business, management, and economics for the selected time (2014–2024). The research on the work-life balance of teachers has seen significant growth, especially during the COVID-19 pandemic. The findings highlight that the USA in countries, Fokkens-Bruinsma, M. in authors and Frontiers in Psychology in sources have the highest contribution of articles in related field. Key topics include “human,” “teaching,” “work-life balance,” “questionnaire,” and “education. This study provides a comprehensive overview of the research trends, key contributors, and important topics in the field of work-life balance of teachers. Moreover, it also highlights the growing interest in this area and the need for further research to address the challenges faced by educators. The findings suggest that implementing work-life policies and initiatives tailored to the teaching profession can help address these challenges and promote better well-being among teachers. Overall, the study calls for a greater focus on supporting teachers to ensure they can effectively manage their work and personal responsibilities.

This review presents machine learning (ML) approaches from an applied economist’s perspective. We first introduce the key ML methods drawing connections to econometric practice. We then identify current limitations of the econometric and simulation model toolbox in applied economics and explore potential solutions afforded by ML. We dive into cases such as inflexible functional forms, unstructured data sources and large numbers of explanatory variables in both prediction and causal analysis, and highlight the challenges of complex simulation models. Finally, we argue that economists have a vital role in addressing the shortcomings of ML when used for quantitative economic analysis.
