This study examines the phenomenon of “foolishness for Christ” as reflected in the contemporary Orthodox figure of Elder Gerontius of Tismana. Starting with a general review of the diverse phenomena of divine madness present in various world religions, we then move onto the Orthodox Christian tradition, where such apparent eccentric behavior is interpreted as an expression of deep asceticism and spiritual insight. Based primarily on memorial and testimonial sources (oral accounts, written recollections, and biographical notes), the research employs a hermeneutical and phenomenological approach to interpret how such figures are perceived within ecclesial life. Using Christos Yannaras’ theological criteria for discerning authentic “holy folly”, our paper argues that Elder Gerontius convincingly fits this ascetic paradigm. The study further suggests that the presence of such charismatic and unconventional figures may signal a form of spiritual renewal within contemporary Orthodoxy, revealing the dynamic interplay between prophetic charisma and institutional order in the life of the Church.

Insufficient investment in wildlife that lacks strong aesthetic or emotional appeal to humans poses a significant obstacle to achieving broader conservation goals. Species that are not considered charismatic are nonetheless vital to ecosystems and deserve attention from conservationists, researchers, and the public. However, effective strategies for bridging the gap between these species and traditionally charismatic ones remain underexplored. Our exploratory study introduced the concept of charisma orientations to examine their influence on pro-bird behaviors, such as following guidelines, reporting disturbances, and participating in community advocacy. We identified six relational and socially negotiated orientations—ecological importance, intrinsic right to exist, protection support, affective meaning, and perceived decline—that together represent key perspectives through which waterbirds are understood. A survey of 615 Texas coastal recreationists revealed that relying solely on positive charisma diminishes the appeal of waterbirds for participants. The species likeability frame was relevant only in the context of reporting disturbances, while a moral policy stance (the belief that waterbirds need protection) was significant in predicting advocacy. Younger males and individuals who felt current regulations were adequate were less likely to engage in waterbird conservation behaviors. Our findings suggest that examining the intersection of contested charismatic species and various charisma orientations can uncover subtle nuances often overlooked due to an overemphasis on positive charisma and emotional resonance, which may only partially apply or not apply at all.

Moving beyond the debate on cultural continuity, this article investigates the micro-mechanisms by which charismatic experiences are produced and authenticated in a True Jesus Church (TJC) community in Southern Fujian. Based on ethnographic fieldwork conducted between 2022 and 2024, the study proposes the concept of “making testimonies” to trace the social production of charisma. The analysis identifies three consecutive stages in this mechanism: (1) in everyday interaction, pastoral rhetorical prompting anchors believers’ scattered sensory experiences to church-recognized experiential types; (2) in ritual settings, complex life histories are disciplined into standardized narratives of “grace and conversion” to align with communal identity; and (3) through mediatization, oral accounts are verified, edited, and fixed into an authoritative archive of collective memory. The study argues that these practices are not expressions of “indigenization” but are strategically employed to construct an authenticity that validates the TJC’s theological claim as the “exclusive church of salvation.” By revealing how modern organizational power and media technologies configure the local “landscape of the Spirit,” this research offers a dynamic, practice-oriented framework for understanding Chinese Christianity.

Bacterial biofilms pose significant challenges in clinical, industrial, and environmental settings due to their inherent resistance to antimicrobial agents and host immune responses. Encased within a self-produced extracellular polymeric substance (EPS) matrix, these structured microbial communities demonstrate exceptional resilience, resisting conventional antimicrobial treatments and adapting to, as well as recovering from, environmental and therapeutic stresses, necessitating the development of novel anti-biofilm strategies. This review provides a comprehensive synthesis of biofilm formation, resistance mechanisms, and current and emerging approaches for controlling biofilms, with a primary focus on advancements made over the last decade. Chemical, physical, and biological strategies, including enzymatic degradation, natural compounds, chelating agents, nanoparticles, photodynamic therapy, and probiotics, have demonstrated promising antibiofilm activity. Additionally, combination therapies and targeted drug delivery systems have emerged as viable solutions to enhance the eradication of biofilms. Despite these advancements, challenges such as cytotoxicity, bacterial adaptation, and clinical applicability remain. Addressing these hurdles requires interdisciplinary research to refine existing strategies and develop innovative solutions for effective biofilm management. Full article

The leadership of Sukarno, the first President of post-colonialized Indonesia, stands at the center of this paper. It is commonly accepted that Sukarno played an important role in liberating Indonesia from Dutch colonialism. He was distinguished statesman and respected leader, a “magical verbalizer” and a modern millenarian figure in the Indonesian political cultural context. My purpose in this paper, then, is to analyze Sukarno’s major elements of leadership in order to learn from his biography how educational leaders could manage their educational institution more effectively, particularly in traditional developing nations. A biographical analysis of Sukarno’s leadership reveals four major elements in his leadership: charisma, harmony, and an open-minded view of reality, unity building, guided democracy, and respect. Practical implications for leadership development programs in education are suggested at the end of the paper. Full article

Although ochratoxin A (OTA) contamination has been previously reported in Lebanon, this study is the first worldwide to assess its potential impact on renal health among adolescents aged 10 to 18 years. In this cross-sectional study, the aim was to evaluate the levels of OTA, OTα, and kidney injury biomarkers, as well as creatinuria and total proteinuria, while correlating these findings with dietary patterns. Urinary concentrations of OTA, its main metabolite ochratoxin α (OTa), the three renal injury biomarkers (N-acetyl-β-D-glucosaminidase [NAG], Kidney Injury Molecule-1 [KIM-1], and human lipocalin-2 [NGAL]), and two renal function indicators (creatinine and total protein) were quantified. Associations between biomarker levels and dietary intake patterns were also evaluated. OTA and OTα were detected in 14.2% and 59.5% of urine samples, respectively. NGAL and NAG were found in all participants at low concentrations, with the NAG-to-creatinine ratio exceeding the clinical threshold in 1.5% of samples, while KIM-1 was detected in 86% of participants. A weak positive correlation between urinary OTα and NAG suggests subtle renal alterations possibly linked to OTA exposure. Correlations between biomarker levels and food consumption were generally weak and positive. Estimated dietary intake (EDI) of OTA generated from consumption patterns was shown to be less than the probable dietary intake (PDI) calculated from urinary OTA. However, this presented a limitation, as EDI was calculated from previous contamination data in Lebanon. Overall, these findings indicate that while renal injury biomarkers were present at low levels, they may reflect early kidney stress not yet manifesting as overt pathology and highlight the need for strengthened regulatory measures to limit OTA contamination in foods available on the Lebanese market and for longitudinal studies to confirm these preliminary findings.

This paper introduces the concept of algorithmic charisma to explain how leadership authority is sustained through visibility, virality, and platform amplification. Using Elon Musk as an illustrative case, it examines “Muskism”—the evolving set of myths, narratives, and symbolic performances that surround Musk and his ventures. Based on publicly available material from 2008 to 2025, the study applies four complementary lenses: charismatic authority, media mythmaking and ritual, organizational cult dynamics, and scapegoating/sacrificial mechanisms. The analysis traces Muskism’s trajectory across four phases—myth construction, polarization and institutionalization, charismatic decay, and symbolic reconfiguration—showing how founder myths are built, contested, and adapted in the platform era. The central contribution is the articulation of algorithmic charisma as a distinct form of founder authority, sustained less by stable belief than by recursive cycles of digital visibility. In doing so, the essay advances understanding of founder-led leadership cultures, highlighting the durability of early mythic framing, the role of audience segmentation in sustaining charisma, and the value of integrating multiple theoretical perspectives in interpretive organizational research.

(1) Background: Gastric cancer continues to pose a significant public health challenge, with its incidence influenced by various factors, including Helicobacter pylori (H. pylori) infection. In Lebanon, data on H. pylori prevalence and its associated risk factors remain limited. This study aimed to determine the prevalence of H. pylori infection among Lebanese outpatients presenting with gastrointestinal symptoms undergoing gastroscopy, to explore correlations between the infection and demographic and clinical variables, and to evaluate the prevalence of associated conditions such as gastritis, duodenitis, and intestinal metaplasia. (2) Methods: Using a retrospective design, data from 786 patients admitted at a hospital in Beirut over a three-year period were extracted from records. (3) Results: The prevalence of H. pylori infection was 29.6% despite 91.5% of patients showing signs of gastritis on endoscopy. The infection showed significant associations with erosive gastritis, non-erosive gastritis, mosaic gastritis, as well as with both erosive and non-erosive duodenitis. No significant relationships were observed between H. pylori and demographic factors, atrophic, or nodular gastritis. (4) Conclusions: These findings underscore the importance of targeted testing and early eradication of H. pylori to manage gastritis effectively and reduce the risk of progression to more serious gastric conditions in the Lebanese population.

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental pollutants of emerging concern due to their widespread use and potential adverse health effects. This study assessed the concentrations of key PFAS compounds in yogurt samples collected from eleven Lebanese governorates. Results revealed notable geographic variability, with the Bekaa region exhibiting the highest PFAS levels, particularly PFHpA, PFOA, PFHxS, PFOS, and PFPeA, while Jbeil showed the lowest concentrations. Health risk assessment using estimated daily intake (EDI), risk quotients (RQ), and cumulative hazard index (HI) indicated all individual compound exposures below established safety thresholds. However, elevated RQs for PFOS and PFOA and an average HI of 0.71 suggest potential chronic exposure concerns in high-burden regions. These findings emphasize the importance of continued monitoring and risk management to protect public health and inform environmental policies addressing PFAS contamination in Lebanon. Full article

Background: Undernutrition and overnutrition are considered a rising challenge among adolescents in low- and middle-income countries, including Lebanon, where overlapping economic, political, and public health crises have worsened food insecurity. Food and nutrition literacy in adolescents may serve as protective factors against food insecurity and its nutritional consequences. This study aims to evaluate the associations between adolescent and parental food and nutrition literacy with household and adolescent food insecurity, and explores their relationship with stunting and overweight/obesity. Methodology: A cross-sectional survey was conducted between March and July 2022 among 442 Lebanese adolescents (10–18 years) and one parent/caregiver per household, recruited via snowball sampling from all eight governorates. Validated tools assessed adolescent food and nutrition literacy, parental food literacy, household/adolescent food insecurity, and anthropometric status. Chi-square, t-tests, and multivariable logistic regressions identified factors associated with food insecurity, stunting, and overweight/obesity. Results: Higher adolescent food and nutrition literacy was significantly associated with lower odds of severe food insecurity (aOR = 0.43, 95% CI: 0.26–0.70). Higher parental food literacy scores were linked to reduced odds of severe household food insecurity (aOR = 0.94, 95% CI: 0.90–0.98). Severe food insecurity was more likely in households in Akkar and among adolescents not attending school or with poor food and nutrition literacy. Overweight/obesity was positively associated with attending private school and higher parental body mass index, but inversely associated with higher child food security and household crowding index. No significant association was found between food insecurity and stunting. Conclusions: Both adolescent and parental food and nutrition literacy are protective against severe food insecurity, highlighting the value of literacy-focused interventions alongside economic support measures. Addressing both educational and structural determinants may help break the cycle of malnutrition in crisis-affected Lebanese youth. Full article

Background: Taekwondo (TKD) athletes’ nutritional and health statuses and body composition are critical to their physical performance and overall fitness. In Lebanon, TKD is widely practiced; however, there is a significant gap in the literature regarding the nutritional and health profiles of its athletes. This study aimed to assess the nutritional status, anemia prevalence, body composition, and other health-related characteristics, among Lebanese TKD athletes. Additionally, it explored the determinants of normal hemoglobin (Hb) levels, blood pressure, normal muscle mass, and normal fat mass. Methods: A cross-sectional study was conducted between January and July 2023, involving 110 TKD athletes. Hemoglobin and hematocrit levels were measured to assess anemia, while body composition was evaluated using a bioelectrical impedance analyzer. Blood pressure was also recorded. Household dietary diversity was assessed using the Food Consumption Score, and additional data on sociodemographic factors, training frequency, and supplement or medication use were gathered through a structured questionnaire. Logistic regression models were applied to identify predictors of normal Hb levels, hypertension, and optimal muscle and fat mass. Results: Results showed that male athletes had significantly higher rates of normal Hb (p-value = 0.013) and muscle mass percentages (p-value < 0.001), while females had higher rates of normal blood pressure (p-value = 0.002) and were more likely to use iron supplements (p-value = 0.002) and painkillers (p-value = 0.041). Normal fat mass was positively associated with normal Hb levels (aOR: 11.98, p-value = 0.033). Female gender was linked to a lower likelihood of normal muscle mass (aOR: 0.13, p-value < 0.001) and hypertension (aOR: 0.19, p-value = 0.009). Higher training duration (10 h or more per week) (aOR: 3.46, p-value = 0.04) and normal BMI (aOR: 4.93, p-value = 0.003) were positively associated with normal muscle mass. Normal BMI (aOR: 14.68, p-value < 0.001) was positively associated with normal fat mass. Conclusion: These findings underscore the importance of individualized dietary interventions to enhance athletes’ overall health and performance, through the optimization of athletes’ body composition, and the prevention of deficiencies, especially iron deficiency.

Introduction: Nutrition literacy has garnered growing research attention worldwide, yet only a few instruments have been developed to specifically measure this construct among adolescents. Accordingly, the present research sought to examine the validity and reliability of the Adolescent Nutrition Literacy Scale (ANLS) within a group of Lebanese adolescents. Methods: A cross-sectional study was carried out from December 2022 to March 2023, targeting a nationally representative sample. Results: Fit indices of the three-factor structure were good. Internal reliability was adequate for the following three subscales: Functional Nutrition Literacy (FNL) (ω = 0.88/α = 0.88), Interactive Nutrition Literacy (INL) (ω = 0.87/α = 0.86) and Critical Nutrition Literacy (CNL) (ω = 0.89/α = 0.89). Invariance was established across genders at configural, metric, and scalar levels. A significantly higher mean FNL and INL scores were found in males compared to females, with no significant difference between the two genders in terms of CNL. Higher FNL, but not CNL and INL scores were significantly associated with lower child food security. Conclusions: The Arabic ANLS has exhibited robust psychometric reliability, validity, and cost-effectiveness as a tool for assessing nutrition literacy. By utilizing the Arabic version of the ANLS, we can more efficiently and accurately assess the nutritional literacy of adolescents. Full article

How leaders communicate with followers is a core element of leadership. However, research on leader communication techniques remains fragmented, limiting our understanding of their differential effects on follower cognition, affect, and behavior. To facilitate systematic research comparing the effects of different communication techniques, we propose a framework for leader communication techniques. We hypothesize that different communication techniques can be categorized into cognitive, affective, and behavioral leader communication techniques that influence cognitive, affective, and behavioral follower outcomes, respectively. To test this assumption, we developed and pre-tested video vignette material, which we then used in a between-subjects experiment in the military context. We assigned 368 military recruits to one of the three conditions (cognitive versus affective versus behavioral) to examine how these techniques relate to proximal and distal follower outcomes. We found few differences in the impact of cognitive, affective, and behavioral leader communication techniques on follower outcomes. The leader was perceived similarly, regardless of the communication techniques used. Only for specific affective follower outcomes (i.e., warmth and charisma of the leader), affective leader communication techniques were more effective than cognitive and behavioral techniques. We discuss implications for leader communication research, outline practical implications for leaders, and propose directions for future research. Full article

Biomimetic restorative protocols aim to preserve natural tooth structure while enhancing restoration longevity. This in vitro study aimed to evaluate the shear bond strength (SBS) in the repair of additively and subtractively manufactured CAD/CAM materials using bulk-fill resin composites and to assess the effect of thermocycling. Forty rectangular specimens (14.5 × 7 × 3 mm) were prepared from Grandio Blocs (GB, VOCO) and VarseoSmile Crown^Plus (VS, BEGO), and thermocycled (5000 cycles, 5–55 °C, 20 s dwell time). All surfaces were roughened with 50 μm Al₂O₃. Samples were repaired using VisCalor (VCB, VOCO) and Charisma Bulk Flow One (CBO, Kulzer) composites (n = 10 per group) with their respective adhesives. Each group was further divided into immediate and post-thermocycling subgroups. All specimens were tested under shear force until failure, and failure types were examined under a stereomicroscope. Representative samples were examined by SEM to evaluate filler morphology. Statistical analysis was performed with SPSS v23 (p < 0.05). No statistically significant differences in SBS were found between groups (p > 0.05). Mean SBS values were highest in VS-CBO and lowest in GB-CBO. Cohesive failures were more frequent in immediate groups, while adhesive failures predominated after thermocycling. Bulk-fill composites did not influence the repair bond strength of indirect materials. Thermocycling affected the failure type, though not the SBS values. Full article

The toxicity of metals such as lead (Pb) and cadmium (Cd) makes heavy metal contamination in food products a major health concern. The aim of this study is to measure the levels of Pb and Cd in yogurt samples that were collected from 11 distinct Lebanese locations and determine their compliance with the legal limits set by the European Commission (0.02 mg/kg for Pb and 0.005 mg/kg for Cd). A total of 165 yogurt samples were examined using atomic absorption spectrophotometry (AAS). Interestingly, the findings showed that 10.9% of samples had Pb concentrations over the allowable limit; the highest amounts were observed in Baalbeck-Hermel (0.118 mg/kg), North Area (0.125 mg/kg), and South Lebanon (0.115 mg/kg). In addition, the highest detected concentrations of Cd were found in North Area (0.094 mg/kg), Baalbeck-Hermel (0.076 mg/kg), and Akkar (0.042 mg/kg), with 14.5% of samples above the limit. The results show regional differences in contamination, which are probably caused by industrial emissions, agricultural activities, and environmental pollution. To better understand the potential health implications, the estimated daily intake (EDI) of Pb and Cd through yogurt consumption was calculated and compared to international health-based guidance values. Although the EDI values suggest a low risk from yogurt alone, the findings highlight the importance of cumulative exposure and emphasize the necessity of regular monitoring and stricter implementation of food safety laws to decrease exposure to heavy metals through dairy intake.
