Background/Purpose: In an increasingly competitive educational landscape, the school principal’s role has expanded beyond instructional leadership to include strategic marketing responsibilities. Yet the role of marketing in school leadership remains underexplored. Our objective was to investigate how Greek secondary school principals perceive marketing’s key dimensions (Customer Orientation, Competitor Orientation, and Inter-Functional Coordination) within schools, in comparison to other school staff members. Design/Methodology: A cross-sectional survey design was employed, collecting data using a structured questionnaire adapted from Oplatka and Hemsley-Brown. The sample comprised 350 respondents, including school principals and teaching staff. One-way ANOVA, supplemented by Games–Howell and Kruscall–Wallis tests, was employed to examine group differences across the three dimensions of market orientation. Results: Our findings indicate that principals demonstrate a higher level of Customer Orientation than other staff. However, no significant differences were found in Competitor Orientation or Inter-Functional Coordination across roles. Conclusions/Novelty: The findings suggest that while principals play a key role in aligning school functions and engaging with internal stakeholders, their sensitivity to external competition remains limited. The study highlights the evolving nature of school leadership while showing that marketing strategies in Greek schools are insufficiently implemented, calling for research into how leadership training can enhance market responsiveness.

Sri Lanka, then known as Ceylon, was ruled by three Euro-Christian colonisers for over 450 years. Alongside their pursuit of trade and wealth, these colonial powers—the Portuguese (1505–1658), Dutch (1658–1796), and British (1796–1948)—sought to establish their distinct forms of Christianity: Catholicism by the Portuguese, Reformation by the Dutch, and Anglicanism and other Protestant denominations by the British. The missionary strategies and religious policies of these European colonisers varied significantly. Unlike Catholicism, which closely aligned with the external rituals of local religions such as Buddhism and Hinduism, the Dutch Reformed religion emphasised Christian doctrine and biblical scripture, distinguishing itself in its liturgy, art, and architecture. This paper examines the origins and development of Dutch Reformed urban church architecture in Sri Lanka through archival, cartographical, and morphological research, complemented by an architectural survey of the surviving Dutch Reformed churches. The study reveals that the Dutch initially repurposed several Portuguese churches for Reformed worship, and later, they introduced the “Meeting House” typology, aligning with Reformed ecclesiastical and liturgical principles. Over time, this evolved into larger “Greek Cross Plan” churches, a trend that continued until the rise of Anglicanism. Full article

This feasibility study investigates the relationship between functional food consumption and mental well-being, focusing on natural foods traditionally linked to mental health benefits. This research also examines consumer preferences to identify key characteristics that novel functional foods designed to enhance mental well-being should possess. Additionally, this study lays the groundwork for a clinical trial exploring the effects of a novel functional food on mental health and well-being. Data were collected through an online bilingual survey (Greek/English) from 362 participants across Greece and Cyprus, using an adapted Functional Food Frequency Questionnaire (FFFQ) featuring 30 foods with documented effects on cognitive function and mood regulation. The survey included validated scales measuring mental well-being, health-related quality of life (HRQoL), sleep quality, and food choice motives, along with demographic and anthropometric data. Analysis revealed significant associations between functional food consumption and mental health outcomes, particularly in HRQoL, sleep quality, and body mass index (BMI). Most functional foods consumed were natural and aligned with the Mediterranean dietary pattern, such as fruits, vegetables, nuts, herbal infusions, and honey, all demonstrating positive effects on mental and physical health. Consumer preferences showed a strong inclination toward functional foods that balance sensory appeal with health benefits, including milk-based and plant-based beverages, protein bars, and granola bars. Ingredients like St. John’s wort and Greek mountain tea were identified as potentially beneficial for mental well-being, consistent with their established efficacy in psychological health. A significant majority of participants (66.9%) expressed interest in participating in clinical trials, highlighting the need for further research into the efficacy of functional food components. This study provides a foundation for future clinical trials examining the impact of novel functional food formulations on mental and physical health, addressing the growing consumer demand for products that enhance psychological resilience and well-being.

Commercial tomato hybrids exhibit robust performance in modern high-input agricultural systems. However, their suitability for low-input farming remains uncertain. With the goal that by 2030, 25% of European agricultural production must be organic as part of the European Green Deal, this study aims to assess whether existing commercial tomato hybrids can offer a viable solution for low-input farming. Additionally, the impact of beneficial microorganisms such as plant growth-promoting rhizobacteria (PGPR), in relation to the growth and productivity of tomato hybrids under low-input cultivation is assessed. For this purpose, a well-defined microbial consortium, including Azotobacter chroococcum, Clostridium pasteurianum, Lactobacillus plantarum, Bacillus subtilis, and Acetobacter diazotrophicus, was applied as a liquid suspension to enhance root colonization and promote plant growth. Seven commercial tomatoes (Solanum lycopersicum L.) hybrids—the most popular in the Greek market—were evaluated for their performance under high-input (hydroponic) and low-input cultivation systems (with and without the use of PGPR). Several parameters related to yield, fruit quality, nutritional value, descriptive traits, and leaf elemental concentration were evaluated. In addition, a techno-economic analysis was conducted to assess whether hybrids developed under high-input conditions and intended for such cultivation environments suit low-input farming systems. The results indicated that such hybrids are not a viable, efficient, or profitable strategy for low-input cultivation. These findings underscore the importance of breeding tomato varieties, specifically adapted to low-input farming, highlighting the need for targeted breeding strategies to enhance sustainability and resilience in future agricultural systems. Notably, this study is among the first to comprehensively assess the response of commercial tomato hybrids under low-input conditions, addressing a critical gap in the current literature.

Background: The attitudes and beliefs of patients with chronic pain significantly affect their response to treatment. The Survey of Pain Attitudes (SOPA) scale was developed to identify pain-related beliefs. The aim of the present study was to adapt and validate the short version (30 items) of the Survey of Pain Attitudes in 200 Greek patients living with chronic pain, mainly due to rheumatic and musculoskeletal diseases (RMDs). Method: In addition to the SOPA-Brief scale (30 items), the participants completed the Pain Beliefs, Perceptions and Attitudes Inventory (PBAPI) and also the Chronic Pain Coping Inventory (CPCI). Results: Data analysis revealed that the internal reliability coefficient of the scale in the Greek language was Cronbach’s a = 0.773 for the individual items, and for the subscales, it ranged from Cronbach’s a = 0.56 (for the SOPAMedication scale) to Cronbach’s a = 0.78 (for the SOPASolicitude scale). Similarly, the SOPA-Brief subscales in Greek showed positive correlations with subscales of both the PBAPI and the CPCI. Finally, an exploratory factor analysis was performed on the dataset and confirmed the structure of the original scale (Eigenvalues > 1), with 71.54% of variance explained. Conclusions: Overall, the psychometric properties of the short version of the Attitudes Towards Pain Scale (30 items) in Greek show acceptable internal reliability and validity for the scale to be used in daily clinical and research practice.

The European ground squirrel (Spermophilus citellus) is an endangered mammal that inhabits open habitats with low vegetation in central and southeastern Europe. Its southernmost range includes northern Greece, where populations are declining due to habitat degradation and fragmentation. Limited behavioural research on Greek populations underscores the need for studies to support conservation efforts. The present study examined the species’ diet and seasonal changes in food consumption in an anthropogenic area of Central Macedonia, Greece. Between 2022 and 2023, feeding behaviour was documented recording plant parts, taxa, and feeding durations, while plant availability was assessed through surface sampling. The results revealed that Cynodon, Carex–Cyperus, Salvia, Solanum, and Plantago were the dominant plant genera in the species’ diet, while rhizomes and leaves were the most frequently consumed plant parts. Seasonal dietary shifts were observed, with ground squirrels selecting specific plants and plant parts based on availability. Under resource-limited conditions, they adapted by consuming nutritious rhizomes or the less-common, but toxic, S. elaeagnifolium. These findings highlight the species’ dietary adaptability to Mediterranean and human-modified environments, providing valuable ecological insights and informing habitat conservation and improvement strategies.

The Askisi-Spelling Deficits (SD) neuropsychological web-based screener was developed to assess cognitive and spelling abilities in children, with an emphasis on the early detection of spelling disorders. This tool incorporates six tasks that evaluate cognitive domains, such as visual and auditory working memory, response inhibition, and spelling processing, providing a comprehensive framework for assessment. A study conducted with 264 Greek children, including 132 children with spelling deficits and 132 typically developing controls, aimed to implement this screening tool. Results indicated that the screener was effective, as children with spelling deficits showed significantly lower performance and longer response times across all tasks. The tool’s internal consistency was supported by split-half correlations (r = 0.64) and Spearman–Brown coefficients (r = 0.78). Nonetheless, certain limitations were identified, including the absence of latency data for specific tasks (Go/No-Go and working memory), as well as the screener’s cultural specificity, which might limit its applicability to other linguistic and orthographic systems. Future iterations should prioritize the inclusion of timing mechanisms for more detailed assessments and consider adaptations for use in languages with varying orthographic complexities. Expanding the demographic reach and conducting longitudinal validation studies would further improve its utility and generalizability. The web-based nature of the screener enables scalable and standardized administration, making it a practical and efficient tool for the early identification of spelling difficulties in children.

Despite the efforts to advance children’s rights’ protection, many children’s rights are still not respected in many places. This makes it more necessary than ever to raise the awareness of children’s rights and prepare new generations of students to protect children’s rights via empowering them to engage in activism. Drawing upon human rights education (HRE) models in conjunction with UNICEF’s methodologies, and the theory of planned behaviour (TPB), the current conceptual article suggests that by designing theoretically based engaging and meaningful learning activities, teachers can address the goals of HRE by raising the awareness of children’s rights, fostering accountability, and encouraging students to engage in activism to protect children’s rights. First, this article outlines a conceptual framework for designing meaningful and engaging learning activities within an adapted HRE model, combining the elements of HRE and UNICEF. Next, the educational innovation of Skills Labs in Greek education is introduced, and the TPB’s foundation on designing learning activities is briefly explained. To clarify our proposal, three sample Skills Labs with example learning activities are presented, adhering to the three main HRE objectives of gaining knowledge–taking responsibility–taking action to protect and consolidate children’s rights. Finally, this article explains the mechanism of how the TPB can support the effectiveness of this proposition and concludes with some important implications for practice. Full article

Climate change is one of the most pressing global threats, endangering the sustainability of the planet and quality of life, whilst urban mobility significantly contributes to exacerbating its effects. Recently, policies aimed at mitigating these effects have been implemented, emphasizing the promotion of sustainable travel culture. Prior research has indicated that both environmental awareness and regulatory efforts could encourage the shift towards greener mobility; however, factors that affect young people’s travel behavior remain understudied. This study examined whether and how climate change impacts travel behavior, particularly among Generation Z in Greece. A comprehensive online survey was conducted, from 31 March to 8 April 2024, within a Greek academic community, yielding 904 responses from Generation Z individuals. The design of the survey was informed by an adaptation of Triandis’ Theory of Interpersonal Behavior. The study also incorporated a comparative analysis using data from the UK’s National Travel Attitudes Survey (NTAS), offering insights from a different cultural and socio-economic context. Blending an Exploratory Factor Analysis and latent variable ordered probit and logit models, the key determinants of the willingness to reduce car use and self-reported reduction in car use in response to climate change were identified. The results indicate that emotional factors, social roles, and norms, along with socio-demographic characteristics, current behaviors, and local environmental concerns, significantly influence car-related travel choices among Generation Z. For instance, concerns about local air quality are consistently correlated with a higher likelihood of having already reduced car use due to climate change and a higher willingness to reduce car travel in the future. The NTAS data reveal that flexibility in travel habits and social norms are critical determinants of the willingness to reduce car usage. The findings of the study highlight the key role of policy interventions, such as the implementation of Low-Emission Zones, leveraging social media for environmental campaigns, and enhancing infrastructure for active travel and public transport to foster broader cultural shifts towards sustainable travel behavior among Generation Z.

The anthropogenic origin of climate change is well-documented in the scientific literature, with agriculture recognized as both a significant contributor and a sector highly vulnerable to its impacts. This dynamic creates a vicious circle, where farming activities exacerbate climate change, while farmers simultaneously bear its adverse consequences. As a result, they play a pivotal role in both mitigation and adaptation efforts. Using this as a starting point, the overarching aim of the present study is to investigate farmers’ climate change views and to indicate how farmers envisage their role, responsibilities, and possibilities to mitigate and adapt to climate change. To this end, a primary questionnaire survey was conducted based on a sample of 150 farmers in the region of Eastern Macedonia and Thrace in Greece. Principal component analysis (PCA) was conducted in order to identify the key views and attitudes of farmers towards their role and responsibilities about the impact of climate change. Additionally, clustering techniques were employed to classify farmers with similar attitudes, providing a typology regarding their behavior toward climate adaptation and mitigation issues. Lastly, a series of non-parametric statistical tests were performed to profile the identified groups of farmers and additionally to define differences among farmers’ features, agricultural holdings’ features, and cluster solution groups. The results of this process provide a comprehensive understanding of Greek farmers’ views and attitudes towards climate change. Acknowledging farmers’ views and attitudes towards climate change at the national level is crucial for the national and regional authorities in their effort to plan successful future climate policies for the agricultural sector and to ensure success in farm-scale implementation.

Background: The Delis–Kaplan Executive Function System (D-KEFS) Tower Test (TT) is a widely used neuropsychological tool that assesses complex executive functions, including planning, cognitive flexibility, inhibition, switching, and impulsivity—key abilities often impaired in individuals with frontal dysfunction. Aims: There is currently no normative data for the D-KEFS TT in the Greek population. Consequently, it cannot be effectively used to detect executive dysfunction in neurological and psychiatric populations or for research purposes. Methods: The study sample included 249 healthy adults (28.9% male, 71.1% female) aged 20 to 85 years (M = 46.53, SD = 17.41), with educational levels ranging from secondary school graduates to master’s degree holders. Pearson correlation was used to examine the relationship between age and D-KEFS TT performance, while chi-square test assessed the effects of education and gender. Normative data were then derived from raw scores and converted into percentiles. Results: Norms were established for the following D-KEFS TT variables: Total Achievement Score, Total Rule Violations, Move Accuracy Ratio, Mean First Move Time, and Time-per-Move Ratio. Age was the strongest predictor of performance, and normative data were stratified accordingly for the Greek adult population. Conclusions: This study introduces the D-KEFS TT as a neuropsychological assessment tool for Greek adults across different age groups to evaluate complex executive functions throughout the lifespan. Unlike other D-KEFS tests, the TT had not previously been adapted for the Greek population. This study is the first to provide normative data, supporting its use in clinical practice and research.

This study investigates the relationship between sustainable leadership styles and conflict management strategies within the context of Greek Public Sector. Specifically, it examines how collaborative, transformational, and authoritarian leadership styles impact workplace conflict resolution. The research adopts a case study methodology, focusing on Departments of Public Works in Greece, where data were collected through questionnaires. The analysis involved quantitative methods, including exploratory factor analysis (EFA), to examine the relationship between leadership styles and conflict management techniques. Results indicate that collaborative leadership is strongly associated with higher employee satisfaction and more effective conflict resolution, particularly in organizations with flat hierarchical structures. Transformational leadership fosters trust and open communication, which further enhance conflict resolution. On the other hand, authoritarian leadership styles correlate with increased workplace tension, lower satisfaction, and less effective conflict management, especially in high power-distance environments. The study also highlights cultural factors, such as the Greek emphasis on interpersonal relationships, as critical influences on leadership effectiveness. These findings underline the need for culturally adaptive and sustainable leadership strategies and provide practical recommendations for promoting harmony and productivity in Greek organizations.

Background: Spirituality is significantly associated with the quality of life of patients suffering from rheumatic diseases, helping them to cope with pain and improve emotional well-being. There is a gap in the literature regarding the relationship between spirituality, quality of life and treatment adherence in patients with rheumatic diseases, especially rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), as relevant studies, especially in the Greek population, are limited. Aims: The present study aimed to evaluate the effect of medication adherence and spirituality on the quality of life of patients with rheumatic diseases. Methods: This was a cross-sectional study conducted in adult patients with rheumatoid arthritis and systemic lupus erythematosus from the region of Crete. Data were collected via a self-administrated questionnaire consisting of four parts, including questions regarding demographic and clinical information; the WHOQoL-BREF, 3, FACIT-Sp-12, and SMAQ questionnaires were used. The level of statistical significance was set at α = 0.05 for all analyses. Results: The study sample consisted of 115 participants, with the majority being women (90%). The majority of the participants suffered from RA (62%), while 38% suffered from SLE. The mean age of the participants was 49.15 years (SD = 11.7), and 46% described their health as good. We found that the dimensions of spirituality are positively related to the dimensions of quality of life. The peace dimension has a strong correlation with psychological health (r = 0.679, p < 0.001) and overall quality of life (QOL Global, r = 0.671, p < 0.001). Meaning also shows a positive correlation with psychological health (r = 0.563, p < 0.001) and overall quality of life (r = 0.506, p < 0.001), whereas adherence to medication shows a low but positive correlation with overall spirituality (r = 0.192, p = 0.040). Conclusions: The findings support that spirituality can be a protective mechanism, improving the mental resilience and adaptability of patients. This study has the potential to contribute to the development of evidence-based guidelines for the integration of spiritual care into clinical practice, with the objective of enhancing the psychological well-being and overall quality of life of patients with rheumatic diseases.

Background: The germination and early development of Origanum vulgare L. subsp. hirtum (Link) Ietswaart (Greek oregano) were studied to assess the plant’s response to different temperatures. Methods: After germination, seedlings were cultivated in control (25 °C) and cold (15 °C) chambers with standard growth parameters. Comparative analyses of plant morphology and leaf anatomy were conducted to identify structural modifications induced by different temperatures. Physiological evaluations, including photosynthetic pigment measurements, phenolic content, and antioxidant activity, were performed to assess differences between the plants grown under the two temperature conditions. Methanolic extracts from the leaves were tested for cytotoxicity on MCF-7 breast adenocarcinoma cells and SH-SY5Y neuroblastoma cells, as well as on nine microbial strains. Additionally, biomarkers from the leaves affected by temperature changes were determined using LC-HRMS/MS analysis. Results: Comparative analyses revealed distinct structural and physiological modifications under cold conditions. The methanolic extracts from plants grown at 15 °C exhibited notably higher cytotoxic activity in both cell lines but demonstrated no activity against microbial strains. The results highlight the influence of low temperature on enhancing the bioactive properties of Greek oregano. Conclusions: The findings provide valuable insights into the environmental adaptability of oregano, demonstrating the impact of low temperature on its bioactive properties. The therapeutic potential of methanolic extracts cultured at 15 °C is imprinted in cytotoxicity in SH-SY5Y and MCF-7 cells and the absence of any activity against microbial strains. Full article
