Objective: This study measures how consumer evaluations of marketing content (quality and credibility), information needs, and attitudes influence perceived usefulness. It evaluates the subsequent impact of perceived usefulness on content adoption and behavioral intentions. The theoretical framework extends the Information Acceptance Model (IACM) within highly uncertain, emerging market environments. Methodology/Tools: The study employs a descriptive-analytical approach. Primary data were gathered via an online survey targeting a purposive sample of 256 consumers who follow the official Facebook pages of Yemeni companies. Sample size adequacy was validated using statistical power analysis (G*Power). Methodological controls, including Harman’s single-factor test, were implemented to assess common method bias (CMB). Statistical Analyses: Data analysis and hypothesis testing utilized Partial Least Squares Structural Equation Modeling (PLS-SEM). The measurement model assessment included outer loadings, composite reliability (CR), average variance extracted (AVE), and discriminant validity via Fornell-Larcker and Heterotrait-Monotrait (HTMT) criteria. The structural model was evaluated using a bootstrapping procedure with 5,000 resamples to extract path coefficients, direct and indirect effects, and confidence intervals, aligning with the sequential mediation structure of the model. Main Findings: The results reveal a significant positive impact of marketing content quality, credibility, information needs, and attitude toward content on perceived usefulness. Perceived usefulness, in turn, is a critical driver of content adoption. Content adoption exerts a strong positive effect on behavioral intentions. In contrast, attitude toward content has no significant direct effect on behavioral intentions once adoption is included in the model; its influence operates indirectly through perceived usefulness and content adoption. These findings largely support the sequential structure of the IACM and confirm its applicability in a crisis-affected emerging market. Key Implications: Theoretically, this study enriches existing literature by demonstrating that information adoption in volatile settings serves as a strategic risk-reduction mechanism. Practically, it recommends that marketing managers in Yemeni firms design needs-driven, highly credible marketing content. This approach stimulates consumer adoption and fosters electronic Word-of-Mouth (eWOM) engagement.

Purpose: This study examines the impact of strategic management on human resource management (HRM) development in a fragile state context, where evidence remains scarce. Design/methodology/approach: Drawing on the resource-based view (Barney, 1991), dynamic capabilities theory (Teece et al., 1997), and strategic HRM theory (Wright & McMahan, 2011), a quantitative descriptive-analytical approach was employed. Data were collected via a 7-point Likert questionnaire (51 items) from 222 usable responses (92.5% response rate) of administrative leaders in nine Yemeni pharmaceutical manufacturing companies. Analysis was performed using IBM SPSS Statistics 27. Findings: Strategic management is high (M = 5.31, SD = 1.02), while HRM development is moderately high (M = 4.76, SD = 1.35). The model is significant, R = .788, R² = .621, F (5, 216) = 70.84, p < .001. Environmental analysis (β = .37, p < .001) and strategy monitoring and evaluation (β = .40, p < .001) significantly predict HRM development. Originality/value: Extends SHRM theory to conflict-affected pharmaceutical firms, revealing a capability-outcome gap.

This study examines how self-control relates to job satisfaction and whether the four dimensions of work-home interaction mediate this relationship among Romanian employees. Grounded in the strength model of self-regulation and Conservation of Resources (COR) theory, this study claims that self-control functions as a personal resource that both directly sustains positive job attitudes and shapes cross-domain spillover between work and home. Despite growing interest in self-control at work, few studies have modelled work-home interaction as the mechanism linking self-control to job satisfaction, and evidence from Central and Eastern European labour markets remains scarce. Self-reported data were collected from 751 Romanian employees using three validated instruments: the Survey Work-Home Interaction-Nijmegen (SWING), which distinguishes negative and positive work-to-home and home-to-work influence; the IPIP-VIA self-regulation scale; and the job-satisfaction subscale of the Michigan Organizational Assessment Questionnaire. Data were analysed in JASP through descriptive statistics, reliability estimates, correlations, a series of one-way ANOVAs on ten demographic and work-related characteristics, and a covariate-adjusted parallel multiple-mediation model estimated with bias-corrected bootstrapping (5,000 resamples), controlling for age, work seniority and weekly overtime. The model explained 26.2% of the variance in job satisfaction. Self-control exerted a strong positive direct effect on job satisfaction and shaped every work-home dimension in the adaptive direction, reducing both conflict scales and raising both enrichment scales. Three of the four SWING dimensions - negative work-to-home interference, positive work-to-home interaction and positive home-to-work interaction - transmitted significant indirect effects, whereas negative home-to-work interference did not, indicating partial mediation. Notably, the combined positive-impact pathways slightly exceeded the conflict-reduction pathway, underscoring the role of resource gain alongside resource loss. The ANOVA results reinforced these patterns: overtime showed the strongest association with job satisfaction, while older age and longer tenure were correlated with higher self-control and satisfaction and lower work-home conflict. The findings suggest that self-regulation is a meaningful antecedent of job satisfaction, operating through both the reduction of negative impact and the promotion of positive cross-domain resource transfer. In practice, they point to the value of curbing mandatory overtime, offering self-regulation and recovery interventions, and adopting family-friendly policies. Key limitations are the study's cross-sectional design, its dependence on self-reported measures, and a sample composed largely of young female employees.

Rice (Oryza sativa Linnaeus.) production in Nigeria is constrained by abiotic stresses including drought, salinity, and iron toxicity. This study evaluated 30 lowland rice genotypes for tolerance to these stresses using phenotypic, physiological, and agronomic parameters. Drought screening was conducted under field conditions with irrigation withdrawal, while salinity (0, 8, 16 dSm?¹) and iron toxicity (0, 150, 300 ppm Fe²?) were evaluated in screen house experiments. Results revealed significant genotypic variability (p<0.05) for all traits assessed. Under drought stress, FARO 68 exhibited the highest grain yield (1,227.26 kg/ha) and stress tolerance index (STI=2.10), while FARO 34 was most susceptible. Salinity screening identified FARO 44 and FARO 68 as highly tolerant with lowest salt injury scores (1.00-2.33) and maintained grain yields of 25.03-31.17g at 16 dSm?¹. For iron toxicity, Alh Baba, FARO 33, and FARO 44 showed strong tolerance with injury scores ≤1.67 at 300ppm. Correlation analysis identified panicle length and 1000-grain weight as key yield determinants under stress. High heritability (0.77-0.98) and genetic advance estimates for yield traits suggested additive gene action. FARO 16 demonstrated combined tolerance to all three stresses, showing low yield reduction (0.40%) under drought, salinity tolerance at 8 and 16 dSm?¹, and iron toxicity score of 1.00 at 150ppm. These tolerant genotypes represent valuable genetic resources for breeding programs targeting stress-prone environments in Nigeria.

Drawing on the resource-based view and the resource-based theory of the firm, this study investigates the effect of organizational capabilities, together with their dimensions (human, physical, and marketing capabilities), on competitive advantage and its dimensions (quality, cost efficiency, and customer responsiveness) in private hospitals. The study adopts a quantitative, descriptive-analytical approach and employs partial least squares structural equation modeling (PLS-SEM) using SmartPLS 4.0 and SPSS 28. The population consists of 75 private hospitals located in Sana'a, the capital of Yemen, of which 15 hospitals (20 percent) were surveyed. A census sample of 376 managers, deputy managers, and heads of technical and administrative departments was approached, yielding 354 valid responses after outlier screening. The results reveal that organizational capabilities exert a strong and significant effect on competitive advantage (β = 0.463, t = 9.112, p < 0.001). At the dimensional level, human capabilities demonstrate the strongest effect (β = 0.333, t = 6.645, p<0.001), followed by physical capabilities (β = 0.322, t = 7.415, p < 0.001) and marketing capabilities (β = 0.303, t = 6.315, p < 0.001). The measurement model satisfies all reliability and validity criteria (composite reliability = 0.785–0.922; AVE = 0.530–0.755; HTMT < 0.90), and the model exhibits substantial explanatory and predictive power (R² for competitive advantage = 0.746; Q² = 0.591). The study contributes to the literature by providing empirical evidence from a developing-country healthcare context and offers practical implications for hospital managers seeking to configure organizational capabilities as a source of competitive advantage.
