Solar energy production in EU + countries using space–time forecasting
(Springer Nature, 2026-01-09) Grigorescu, Adriana; Lincaru, Cristina; Pirciog Camelia Speranta
The need for renewable energy is underscored by the shift from fossil fuels without compromising economic growth. The European Union’s strategy for resilient energy recognizes solar energy as a crucial resource. In recent years, there has been a significant focus on evaluating renewable energy production, distribution, consumption, storage, and applications. One key aspect of this evaluation is exploring production capacity trends using forecasting models. Our study proposes a space–time forecasting approach using the Curve Fit Forecast tool integrated in ArcGIS Pro 3.3, applied to solar energy in 37 European locations based on 1990–2022 data. The model tested four curved types and identified exponential growth patterns in 54% of cases, with consistent upward trends confirmed through RMSE validation. Outlier detection and 3D spatial–temporal visualization provide diagnostic insight into regional disparities and transformation regimes. This digitally enabled, geostatistical method aligns with the EU’s data-driven energy transition agenda, offering a scalable and interpretable tool for policymakers and planners.
Demographic Dependency and the Future of the European Workforce: A Spatial–Temporal Forecasting Approach
(MDPI, 2026-05-01) Lincaru, Cristina; Grigorescu Adriana; Pirciog Camelia Speranta; Tudose Gabriela
This research paper examines the spatial and time variation of demographic dependency in Europe in a 30-year horizon of the evolution of the demographic dividend regarding the economic dependency ratio (ADR1). We used the Curve Fit Forecast tool to estimate the trends of ADR1 in each of the EU Member States using data on Eurostat projections and a sophisticated geostatistical analysis tool developed in ArcGIS Pro 3.2.2. The findings indicate that the dependency in all countries has increased significantly in a statistically significant manner as the Gompertz function has appeared as the best curve in a third of the cases. It is an S-shaped asymptotic behaviour of this function that effectively describes the nonlinear patterns of acceleration and saturation of demographic ageing. As indicated in the analysis, the European regions are increasingly moving apart, with the southern and eastern nations such as Romania demonstrating the most alarming decline in ADR1. These trends highlight the need to reform labour market policies and social protection mechanisms to an ageing population. The paper combines the curve-fitting, descriptive statistics (median, skewness, interquartile range (IQR)) with time clustering (value, correlation, and Fourier) to provide an effective, replicable approach to early warning and policy prioritisation. Overall, the results highlight the importance of integrating predictive spatial modelling and demographic economics to support anticipatory and evidence-based policy decisions. The proposed approach proves to be a robust and transferable framework, applicable to a wide range of socio-economic phenomena characterised by inertia and structural change. Future research should extend the analysis to subnational levels, incorporate additional explanatory variables, and develop scenario-based simulations, including multivariate Gompertz-type models, to further enhance both predictive accuracy and policy relevance in the context of emerging structural labour scarcity.
Green Jobs in Europe: Contemporary Developments and Future Outlook
(Futurity of Social Science, 2026-05-08) Grigorescu, Adriana; Lungu Diana-Cristina
The rise of green jobs has become a pivotal component of Europe’s transition to a sustainable, low-carbon economy. As the demand for environmentally sustainable practices grows, green employment represents a significant opportunity for economic growth, job creation, and social equity. This paper explores the role of green jobs in the European labour market, focusing on contemporary developments and future trends. It examines the European-level policies and strategies that promote the growth of green employment, including government frameworks, private-sector involvement, and the role of green human resource management. The article also assesses the emerging sectors driving the demand for green jobs and the growing need for green skills across industries. Additionally, the paper addresses the challenges and research gaps in green job policies, including their impacts on social inclusivity, regional disparities, and long-term economic effects. As green jobs become increasingly central to Europe’s sustainability goals, understanding these dynamics is critical for shaping effective policies and strategies. The article concludes by emphasising the need for continued research at the intersection of green employment, sustainability, and labour market policies to ensure long-term socio-economic development and prepare the workforce for future challenges.
Talent Management in Europe’s ICT Sector: A Data-Driven Perspective
(SNSPA/Paradigm Publishing Services, 2026-06-29) Grigorescu, Adriana; Lungu, Diana-Cristina; Voica, Marian Catalin
The information and communication technology labor market in Europe has become one of the fastest growing segments of the economy, reflecting the broader digital transformation that is reshaping industries and societies. Despite this growth, employers and policymakers continue to face structural difficulties, such as a limited supply of skilled professionals, uneven participation across demographic groups, and strong regional imbalances in the availability of talent. The existing scientific literature underlines the growing demand for digital skills but also emphasizes persistent challenges, including gender disparities, mismatches between education systems and industry requirements, and difficulties in achieving cross-border labor mobility. While a considerable body of work has addressed these issues conceptually, fewer studies have employed systematic quantitative evidence to measure the scale of shortages and their variation across European member states. This study applies a quantitative research design based on secondary data from validated European sources, including statistical databases and official labor market monitoring reports. The methodology combines trend analysis for the period 2012 to 2024, cross-country comparisons between highly developed and emerging economies within the European Union, and correlation analysis focused on the relationship between gender balance and skill shortages. The findings highlight four critical dynamics: a near doubling of employment in the information and communication technology sector over the past decade, the persistent underrepresentation of women with only 19.4% of specialists, pronounced regional disparities with some countries reporting more than 65% of vacancies as difficult to fill, and a forecasted shortage of up to 8 million professionals by 2030. By integrating statistical evidence with a talent management perspective, this research contributes to the field by demonstrating how real-time labor data can inform more effective recruitment, reskilling, and mobility strategies, ultimately supporting the sustainable development of Europe’s digital economy.
Manager de IMM : de la național la internațional
(Tritonic, 2024) Mitan, Andreea
Raportul anual asupra sectorului IMM din Uniunea Europeană 2022/2023 arată că IMM-urile rămân coloana vertebrală a economiei Uniunii Europene:
• 99% dintre afacerile din UE sunt IMM-uri.
• Peste jumătate din PIB-ul UE este generat de IMM-uri.
• Aproape două treimi dintre cetățenii europeni lucrează în IMM-uri.
Situația este similară dacă ne uităm la cazul particular al economiei României.
Dacă ești manager al unui IMM dau îți dorești să devii, cartea aceasta te poate ajuta:
• să înțelegi mai bine contextul economic, social și politic global în care se dezvoltă astăzi afacerile;
• să revezi date cheie despre evoluția sectorului IMM din România (în perioada 2007-2024) și despre extinderea afacerilor românești pe Piața Unică Europeană;
• să îți autoevaluezi resursele interne care te ajută să fii un manager bun și să îți faci un plan de dezvoltare.
