This study examines the role of supervisory frameworks in shaping the risk management behavior of Greece’s four systemic banks during the period of 2015–2024. It explores how regulatory reforms under Capital Requirements Regulation II, Basel III, and European Central Bank oversight influenced capital adequacy, asset quality, and liquidity metrics. Employing a quantitative methodology, this study analyzes secondary data from Pillar III disclosures, annual financial reports, and supervisory statements. Key risk indicators (capital adequacy ratio, non-performing exposure ratio, liquidity coverage ratio, and risk-weighted assets) are evaluated in conjunction with regulatory interventions, such as International Financial Reporting Standards 9 transitional relief, the Hercules Asset Protection Scheme, and European Central Bank liquidity measures. The findings reveal that enhanced supervision contributed to improved resilience and regulatory compliance. International Financial Reporting Standards 9 transitional arrangements were pivotal in maintaining capital thresholds during stress periods. Supervisory flexibility and extraordinary European Central Bank support measures helped banks absorb shocks and improve risk governance. Differences across banks highlight the impact of institutional strategy on regulatory performance. This study offers a rare longitudinal assessment of supervisory influence on bank risk behavior in a high-volatility Eurozone context. Covering an entire decade (2015–2024), it uniquely links institutional strategies with evolving regulatory frameworks, including crisis-specific interventions such as International Financial Reporting Standards 9 relief and asset protection schemes. The results provide insights for policymakers and regulators on how targeted supervisory interventions and transitional mechanisms can enhance banking sector resilience during protracted crises.

Self-love is a fundamental psychological construct cultivated throughout human history. In Confucian culture, it is considered the ultimate Ren, while in ancient Greek thought, it serves as the center from which love radiates. Previous qualitative research identified five dimensions of self-love, but these lacked quantitative validation. This study developed the Chinese Adult Self-Love Scale (SLS) based on prior qualitative findings, constructing an initial item bank of 90 statements. The first study assessed the item relevance and clarity, resulting in a preliminary 68-item scale. Exploratory factor analysis (EFA) of 456 participants refined it to a 22-item scale with five indicators. The second study, with 929 participants, examined its reliability and validity. Cronbach’s α exceeded 0.75, and the test–retest reliability after six weeks was 0.66. Confirmatory factor analysis (CFA) supported the scale’s validity (CFI = 0.91, TFI = 0.90, RMSEA = 0.048). This study highlights self-love’s inheritance and development among Chinese adults, as well as its cross-cultural commonalities. It provides a valid, reliable tool for measuring self-love and offers a theoretical foundation for future cross-cultural research. While limitations exist, the findings suggest promising directions for further exploration. Full article

The transformative potential of artificial intelligence (AI) in banking is widely acknowledged, yet its practical adoption often faces resistance from users. This study investigates the factors influencing AI adoption behavior among various stakeholders in the Greek semi-mature systemic banking ecosystem, addressing a critical gap in the relevant research. By utilizing the Technology Acceptance Model (TAM), Unified Theory of Acceptance and Use of Technology 2 (UTAUT-2), and Partial Least Squares Structural Equation Modelling (PLS-SEM) models, data from 297 respondents (bank employees, digital professionals, and the general public) were analyzed. The results highlight the strong relevance of constructs such as Performance Expectancy, Effort Expectancy, and Hedonic Motivation, whereas Social Influence was deemed non-significant, reflecting a pragmatic stance toward AI. Demographic factors like gender and age were found to have no significant moderating effect, challenging traditional stereotypes. However, occupation and education emerged as significant moderators, indicating varying attitudes among professions and educational levels. This study is the first to develop a theoretical framework for AI adoption by Greek banking institutions, offering Greek banking practitioners actionable insights. The findings also hold relevance for countries with similar digital maturity levels, aiding broader AI integration in banking. Full article

The discovery of the Nag Hammadi Codices (NHC) in 1945 rates as one of the two most profound occurrences for Biblical archaeology and interpretation during the last hundred years, along with the Dead Sea Scrolls (1946–1956). The codices allow us to document Christian monastic culture, gnostic Christianity and gnostic offshoots in the desert climate of Late Ancient Egypt. The recovery of the related Codex Tchacos (CT) brought further excitement for contemporary readers by 2006, it being sensational that narratives of “Judas the betrayer” and “doubting Thomas” were found in the whole collection of writings. The text named the [First] Apocalypse of James, significantly, was found to be in both NHC and CT in different Coptic versions (from near the sacred sites of Chenoboskion and El Minya), but yet another more fragmentary version in Greek had turned up much earlier among the huge cache of papyri found at Oxyrhynchus (also, like the other places, on the banks of the Nile). Given the opportunity for comparison, what distinguishes the three versions? Does comparative analysis better tell us what this ancient text is about? Does the strong presence of Gnostic Christian insights in the Coptic texts still imply a historical Jamesian community is being honoured? This paper concentrates on three comparable passages in the three versions that apparently contain historical memories of James and his followers. It works on the reasonable hypothesis that the Greek version of Oxyrhynchus Papyri (P.Oxy. 5533) (hereafter = PO) is prior and read with different purposes than the two Coptic translated versions of CT (CT 2.10–30) and NHC (NHC V,3. 24–44). When a critical approach, involving a socio-linguistic comparison, is applied, we will see that the three versions of the text were not directly related to each other, but that narratives about James the Just were available to desert monastics from the second century CE. The paper argues for a literal transmission of traditions from a Jewish Christian community around James into Egypt, that the textual figure of James in the Oxyrhynchus fragments points to a ‘mutual familiarity’ between PO and CT, while the NHC tradition of James has been further elaborated by processes of compilation and addition.

Phaseolus coccineus L. is a highly valuable crop for human consumption with a high protein content and other associated health benefits. Herein, 14 P. coccineus L. landraces were selected for genetic characterization: two Protected Geographical Indication (PGI) landraces from the Prespon area, namely “Gigantes” (“G”) and “Elephantes” (“E”), and 12 additional landraces from the Greek Gene Bank collection of beans (PC1–PC12). The genetic diversity among these landraces was assessed using capillary electrophoresis utilizing fluorescence-labeled Simple Sequence Repeat (SSR) and Expressed Sequence Tag (EST); Simple Sequence Repeat (SSR) is a molecular marker technology. The “G” and “E” Prespon landraces were clearly distinguished among them, as well as from the PC1 to PC12 landraces, indicating the unique genetic identity of the Prespon beans. Overall, the genetic characterization of the abundant Greek bean germplasm using molecular markers can aid in the genetic identification of “G” and “E” Prespon beans, thus preventing any form of fraudulent practices as well as supporting traceability management strategies for the identification of authenticity, and protection of the origin of local certified products.

The primary sector is particularly important in Greece, especially considering the country’s current financial crisis, which has lasted since 2010. In an innovative way, this paper investigates the role of Contractual Agriculture as a tool for financing farming production costs in Greece. This study presents the findings of a survey of 222 producers, almost half of whom had used the Contractual Agriculture financing tool, utilizing descriptive statistical analysis via correlation analysis, statistical tests and visual plots such as bar charts. The main findings are that financed farmers are more positive than non-financed farmers about the importance and contribution of the value-chain finance of Contractual Agriculture in covering the cost of production. It ensures an uninterrupted supply of agricultural inputs, improves the possibility of negotiating the purchase price of pesticides and achieves more satisfactory bank terms and conditions for agricultural product financing, as well as the possibility of negotiating the purchase price of pesticides. Finally, in line with previous research, this study found that younger age groups are more hesitant to use this innovative financial tool, and producers with a higher level of education are more likely to use it. This study delves into the advantages and disadvantages for banks, farmers and commercial or manufacturing enterprises involved in such contracts, and its findings offer a comprehensive understanding of the practical implications for participants in Contractual Agriculture and for regulators. Hence, it demonstrates potential areas for improvement in the implementation of Contractual Agriculture in Greece, which could contribute to the growth of the Greek primary sector. Full article

The umbilical cord blood (UCB) donated in public UCB banks is a source of hematopoietic stem cells (HSC) alternative to bone marrow for allogeneic HSC transplantation (HSCT). However, the high rejection rate of the donated units due to the strict acceptance criteria and the wide application of the haploidentical HSCT have resulted in significant limitation of the use of UCB and difficulties in the economic sustainability of the public UCB banks. There is an ongoing effort within the UCB community to optimize the use of UCB in the field of HSCT and a parallel interest in exploring the use of UCB for applications beyond HSCT i.e., in the fields of cell therapy, regenerative medicine and specialized transfusion medicine. In this report, we describe the mode of operation of the three public UCB banks in Greece as an example of an orchestrated effort to develop a viable UCB banking system by (a) prioritizing the enrichment of the national inventory by high-quality UCB units from populations with rare human leukocyte antigens (HLA), and (b) deploying novel sustainable applications of UCB beyond HSCT, through national and international collaborations. The Greek paradigm of the public UCB network may become an example for countries, particularly with high HLA heterogeneity, with public UCB banks facing sustainability difficulties and adds value to the international efforts aiming to sustainably expand the public UCB banking system.

The recent circumstances of the COVID-19 crisis have brought significant changes to employees’ personal, as well as organizational, lives. For office workers worldwide, this has come as a result of the abrupt and wide adoption of telework, as organizations rushed to accelerate their digital transformation. This research focuses on analyzing the reception and effect of teleworking, as an imposed measure during the onset of the COVID-19 pandemic, on employees in Greek banking organizations. First, the circumstances and utilization of telework by a banking institution in Greece before and during the COVID-19 crisis are compared by utilizing autoethnographic evidence. Then, we conducted qualitative research with employees of the organization, who were asked to work remotely at 100% capacity, focusing on the way teleworking was performed utilizing information systems (IS), and the effect it had on them. Detailed information and results from interviews are presented and compared to autoethnographic evidence to reach our conclusions. We find that the vast majority of employees are in general positive about having telework as an option, while the time saved by not commuting to their offices is reported as the most positive element of telework. Most employees also reported having worked longer hours and more efficiently while teleworking, while a common concern—in a scenario where telework may become permanent in some form—is if the organization would cover their teleworking expenses. Theoretical and practical implications are explored and presented accordingly. Full article

Lentil (Lens culinaris Medik.) is an essential legume crop providing healthy and nutritious food for people in low- to middle-income countries, worldwide. Lentil roots support symbiotic interactions with soil rhizobia species fostering nitrogen fixation; however, assemblage and diversity of the complete microbial rhizosphere community and the effect of seed genotype and origin remain largely unexplored. In this study we examined, via metagenomic analysis, the effects of seed origin on the rhizosphere’s communities in samples of the famous Greek lentil landrace, Eglouvis, derived from different local farmers and farming systems (including a Gene Bank sample), in comparison to a commercial variety. The landrace exhibited higher rhizosphere microbiome diversity compared to the commercial variety for all indexes. A core microbiome comprised of 158 taxa was present in all samples, while a greater number of unique bacterial taxa was recorded in the landrace samples compared to the commercial cultivar. Notably, landrace samples originated from organic farming had more than double the number of unique taxa compared to conventional counterparts. The study revealed a higher diversity of N₂ fixers and archaea, Crenarchaeota and Thaumarchaeota, in landrace samples and particularly in those derived from organic farming, underpinning the distinct recruiting efficiency of beneficial soil microbes by the landrace.

The aim of this article is to investigate two external flexible forms of employment—the leasing of workers through Temporary Work Agencies (TWAs) and the contracted workers employed through Business Service Providers (contractors). Undoubtedly, these two forms of employment are complex and often give rise to confusion. First, this article reviews the characteristics of these types of workers and the operation of these businesses. Second, it presents the results of a mixed method of empirical research (quantitative and qualitative) regarding contracted workers. Our sample was 365 contracted workers from the cities of Athens, Thessaloniki and Patras, Greece. In particular, quantitative research is conducted using a methodology called RDS (Respondent Driven Sampling) that is innovative in the field of labour economics and labour relations. Some significant findings of our qualitative research are used to improve, extend, and interpret the quantitative results. Our research proves that contracted workers, who are employed at the premises of the banks, are leased workers, and the contracting undertakings usually operate unlawfully as TWAs. Our research proves that Banks in Greece are using “pseudo-contracting” to circumvent the European Directive 2008/104/EC and the Greek Laws 4052/2012 and 4254/2014, both of which provide institutional protection to workers leased through TWAs. In more detail, the relevant European Directive and the Greek Law 4052/2012 provide salary equality and equal labour rights for the leased workers in Greece and the EU, when they share the same qualifications as the permanent employees of the user undertakings. The employers’ aim in adopting this policy is mainly to pay lower salaries to contracted workers, who in practice have the characteristics of leased workers. Full article

The present work is amongst the few that attempt to critically assess the maturity of Business Model (BM) and strategy disclosures of listed firms under the shadow of the new EU reporting directive, the Corporate Sustainability Reporting Directive (CSRD). The novel Practices Evaluation Approach (PEA), developed recently by the Project Task Force on Reporting of Non-Financial Risks and Opportunities (PTF-RNFRO), offers the evaluation framework for this assessment. The PEA delineates and evaluates the maturity of BM and strategy disclosures against qualitative characteristics and content elements drawn from well-accepted, financial and non-financial, reporting frameworks, standards and directives (including the CSRD). Therefore, the PEA provides the advantage of a contemporary and integrated/holistic assessment tool. Specifically, the following seven evaluation criteria are used for the assessment: clarity and comprehensiveness of the overall BM, strategy disclosure, disclosure of the BM’s potential across-time horizons and its dependencies, impacts on sustainability issues, material sustainability issues that are likely to affect the company’s performance, the BM’s exposure to sustainability risks and sustainability opportunities, and sustainability strategy, targets, KPIs and their monitoring and progress. The analysis covered 30 CSR/sustainability reports and connected documents of listed companies operating in 6 key sectors of the Greek economy, i.e., information technology, construction, tourism and transportation, cosmetics, banking and energy. The results of our analysis offer evidence that BM reporting is not holistically developed (i.e., critical components are missing), and the level of development varies across the examined sectors. Moreover, sustainability risks are more stressed, in relevance to opportunities, whilst positive (rather than negative) impacts are mainly disclosed. Also, the quantification of sustainability risks and opportunities does not appear frequently, whilst the interconnections between sustainability strategy and companies’ financial objectives is relatively restricted. The paper concludes by pointing out some critical hints useful for enhancing the maturity of BM and strategy disclosures. Full article

Banks are under criticism that their business models are not adequately sustainable and also that they do not contribute largely to the resolution of the big issues of humanity. For this, banks seek eagerly to develop sustainable and socially responsible strategies as a means for supporting their public image, establishing trusted relationships with society and increasing customer loyalty. Greek banks implement such strategies; however, they seem to have image issues due to the harsh and extended economic crisis that occurred in the country, as well as their policies of the past. It is interesting to investigate the impact of such activities undertaken by institutions with a damaged image, an area that does not seem to have been investigated yet in the relevant literature. The purpose of the paper is to record the supporting activities in culture of the Greek banks and explore the public’s attitude towards them. The research method combines a content analysis on the banks’ websites and published annual reports to specify their actions in culture, and a structured survey to investigate the evaluation of these actions by the public. The findings of this study reveal that the Greek banks pay much attention to the support of culture. These activities have a positive impact on the public’s attitude towards them, but not on customer loyalty. Full article

The purpose of this paper is to examine the issue of portfolio optimization. Optimization consists of minimizing the risk for a given rate of return or achieving a bigger return for a given level of risk. We use historical data from the Bank of Greece to calculate the net return and the standard deviation (std) for each type of property that is available. The objective is to maximize the economic value added (EVA) of a property’s assets portfolio under a specific rate of standard deviation, following the classic Markowitz model (M-V). The stochastic procedure entry in the model uses the Monte Carlo Simulation method with debt to equity (DTE) following PERT distribution for the portfolio’s invested budget, and the net return for the normal distribution with the mean of the expected return and std are taken from historical data, correspondingly. The returns verify that they follow the base assumption of normality through the Lilliefors test in the Greek real estate market. We observe the maximization of EVA and the expected return maximizing concurrently, but the minimizing risk of EVA is diversified with the minimization of portfolio risk. We observe that the max weight that a residential asset takes is 22.7% because a bigger percent reduces both mean and std. The study provides an explicit portfolio optimization procedure under uncertainty in the real estate market and enriches the academic debate about EVA and revenue. Full article

Faba bean (Vicia faba L.) is an important grain legume with high protein content (approximately 25–30%) and high nutritional value. It is broadly cultivated in temperate areas both for human consumption and as animal feed. According to FAOSTAT (2020), the total cultivated area of faba bean reached approximately 2.5 million ha, yielding more than 4.5 million tons. The characterization of the genetic diversity in faba bean is an important parameter for genetic and biodiversity studies, germplasm characterization, and for introducing genetic variability in plant breeding. The present study aims to assess the genetic diversity among 53 Greek, varied faba bean populations provided by the Hellenic Agricultural Organization “DEMETER” seed bank. To determine the genetic diversity of the studied populations, six SCoT DNA markers were used. A total of 114 loci were obtained with 37.95% being polymorphic and 62.05% monomorphic within or between populations. SCoT markers are a useful tool for the detection of genetic diversity among faba bean populations and encourage targeted crossing strategies. The present study is the first step towards the development of an efficient breeding program. Full article

Reacting to extreme uncertainty conditions caused by the global financial crisis, the European Central Bank implemented countercyclical strategy, combining conventional and non-traditional monetary policy tools to stabilize financial markets and euro area economies. We study the impact of the euro area monetary authority policy interventions on equity returns of four systemic Greek banks for the period January 2007 to August 2018. In the first step, we collect and classify interventions to several categories. Then, an event study analysis is carried out to evaluate cumulative abnormal returns. In the second step, a panel regression analysis is performed to identify Cumulative Abnormal Return (CAR) determinants. Our results suggest that expansionary conventional monetary policy interventions significantly affect equity returns of Greek banking institutions, assisting the regional banking equity stability. On the other hand, the harmful consequences of Greek debt crisis limited the effectiveness of non-standard measures. Full article
