This research investigates the mechanisms by which value‐based leadership (VBL) impacts critical organizational outcomes, namely, operational performance (OPP), business performance (BSP), and business survival (BSV). Specifically, it examines the mediating roles of lean sustainability (LES) and sustainable quality culture (SQC) in translating leadership into tangible results. The research employs a quantitative research design using survey data collected from 402 middle and senior‐level managers. The proposed research model and hypotheses were tested using partial least squares structural equation modeling (PLS‐SEM) with SmartPLS 4. A two‐stage analytical approach was followed, involving the evaluation of the measurement model (reliability and validity) and the structural model (path coefficients and mediating effects). The direct effect of values‐based leadership on sustainable quality culture (β = 0.759; t = 26.912; p < 0.001) was identified as the strongest relationship in the model. In the mediation analysis, the indirect effect of values‐based leadership on lean sustainability through sustainable quality culture (β = 0.395; t = 12.494; p < 0.001) emerged as the most prominent mediation mechanism. All seven proposed hypotheses (between H1 and H7) were statistically supported, with coefficients excluding zero within the 95% confidence interval and significance levels of p < 0.001. While the research uses a robust sample of 402 managers, the use of non‐probability purposive sampling may limit generalizability. Future research could adopt longitudinal designs to further validate causal links over time or examine these dynamics across different sectors to determine whether sectoral nuances affect the mediating effect.

The primary aim of this study is to identify the determinants of purchase intention for halal products. The theoretical foundation of the research is based on the VAB Hierarchy Model. Within this framework, the study examines the relationships among religious belief, attitude, and purchase intention. The research data were collected from consumers aged 18 and above through an online survey using a convenience sampling technique. To test the research hypotheses, CB-SEM was employed, and data were analyzed using the AMOS program. The findings obtained from the data of 451 participants indicate that religious belief and attitude are the factors that directly influence purchase intention toward halal products. The study reveals that religious belief has an effect on purchase intention both directly and indirectly through attitude. Furthermore, the positive attitude developed toward halal products has been statistically confirmed to have a significant impact on consumers’ purchase intentions. In addition, attitude plays a mediating role in the relationship between religious belief and purchase intention toward halal products. By empirically examining the primary determinants of halal product purchase intention, this study contributes to the theoretical literature on consumer behavior. Moreover, from an academic perspective aimed at understanding consumer tendencies in the halal product market, the research expands the relevant body of literature.

This study aims to examine the effect of attitude towards Turkish TV series and attitude towards product placement on purchase intention towards Turkish products. A quantitative research approach was used since the research aims to analyze the cause-and-effect relationships between certain variables. The questionnaire technique was used as a data collection tool in the research. The questionnaire was applied to foreign consumers who came to Turkey as tourists and watched Turkish TV series who voluntarily agreed to answer the questionnaire. The research data were collected from foreign consumers in the tourist regions of Istanbul, which were determined by a purposive sampling technique with face-to-face survey methods. Structural equation modeling was used to analyze the data. 464 data were analyzed, and the SmartPLS program was used to test the model. The study results showed that attitude towards product placement and attitude towards Turkish TV series have statistically significant effects on the purchase of Turkish products in TV series.

Purpose: Family firms with comparable resources often diverge sharply in performance, yet the reasons remain unclear. This study examines how three components of perceived familiness – organizational decision-making, family culture and family image – transform into perceived firm performance via non-family employees' perceptions of distributive and interactional justice. Design/methodology/approach: Survey data from 400 white-collar employees in family businesses in Türkiye were used to test a model integrating the resource-based view and social exchange theory. Partial least squares structural equation modeling (PLS-SEM) assessed both the measurement model and the direct and indirect (mediating) structural effects. Findings: Family culture and family image were strong antecedents of both distributive and interactional justice, whereas organizational decision-making had no significant effect on either. Both justice dimensions substantially enhanced perceived firm performance, with distributive justice being the more powerful. Mediation analyses confirmed that culture and image reach performance only through justice, whereas decision-making does not – thereby establishing organizational justice as the mechanism that converts the cultural and image components of familiness into firm-level outcomes. Originality/value: Integrating the resource-based view with social exchange theory, the study shows that family resources are not inherently performance-generating; their value is realized only when employees decode them as fairness. It disaggregates familiness into components that reach performance through different routes, repositions justice from a micro-level attitude to a meso-level mechanism and reconciles the long-standing tension between socioemotional wealth and agency-based accounts of the family effect.

Purpose: This research examinations the dual mediating role of green creativity (GC) in linking environmental innovation practices (EIP) to both sustainable competitive advantages (SCA) and environmental performance (EP) in the context of the renewable energy sector. Design/methodology/approach: A quantitative, cross-sectional design was used. Data were collected via a survey from 637 engineers and managers working in renewable energy companies across Turkey. The reliability and validity of the scales were determined using confirmatory factor analysis (CFA), and the hypothesized mediation effects were tested using mediation analysis using the Jamovi program. The risk of common method bias (CMB) was assessed using the Harman Single Factor Test and found to be acceptable. Findings: The results strongly support the conceptual model. Green creativity was found to have a significant mediating role between environmental innovation practices and sustainable competitive advantage (H1 supported). Furthermore, there was a significant mediating role in the relationship between green creativity, environmental innovation practices, and environmental performance (H2 supported). Research limitations/implications: The primary limitation is the use of cross-sectional survey data, which limits causal inference. Future research should use longitudinal designs and replicate this model across different sectors and emerging economies to increase generalizability. Practical implications: For managers in the renewable energy sector, these findings highlight the need to actively cultivate an organizational environment that supports and rewards green creativity. This proactive investment in creative processes is essential for fully leveraging environmental innovations, maintaining a strong competitive stance, and achieving superior environmental outcomes. Originality/value: The research presents a novel and empirical examination of a dual mediation model incorporating green creativity and provides baseline data from the rapidly developing renewable energy sector in Türkiye – a significant and under-researched market.

This research purpose to investigate the internal mechanism by which organizational culture (OC) affects sustainability (SUS). Utilizing Resource‐Based Views (RBV) and Dynamic Capabilities theory, the study examines the mediating roles of innovative capability (INC), quality orientation (QUO), and organizational innovation (ORI) in the relationship between culture and sustainability. A quantitative research design was adopted, using survey data collected from 416 managers and directors from 500 randomly selected technology‐focused firms operating in Istanbul Technoparks. Data collected between March and June 2025 were analyzed using Partial Least Squares Structural Equation Modeling (PLS‐SEM) via SmartPLS 4 to test the proposed mediating effects. The results provide empirical support for the “culture‐capability‐performance” chain. Innovative capability (H1) and quality orientation (H2) were found to significantly mediate the relationship between organizational culture and sustainability. However, the mediating role of organizational innovation (H3) was rejected. This suggests that structural or results‐oriented innovation alone, without being supported by specific skills and orientations, may not be sufficient to bridge the gap between culture and sustainability in this context. The research is geographically limited to firms within Istanbul Technoparks; this may restrict the generalizability of the findings to other regions or sectors. Furthermore, the data represent the perspectives of senior management; future research could include the views of lower‐level employees to provide a more multi‐layered view of organizational culture.

Purpose: This research examines the direct effects of command-controlled (CCER) and market-incentive environmental regulations (MIER) on green product (GPRI) and process innovation (GPCI) and sustainable economic (SEMA), social (SSMA) and environmental marketing activities (SENMA) and the contribution of these interactions on strategic performance (STP). Design/methodology/approach: Data were collected from 400 firms in Türkiye using a survey technique, one of the quantitative research methods. These data were analyzed using SmartPLS 4 software and structural equation modeling. Findings: The findings reveal that CCER positively influences GPRI-GPCI and SEMA-SSMA. However, we found that MIER positively affects GPCI and negatively affects SEMA. Furthermore, GPRI and SEMA-SSMA positively impacted STP. Additionally, GPRI and SEMA-SSMA mediate the relationship between CCER and STP. Moreover, the results indicate that MIER influences STP through SEMA. Originality/value: This study contributes to the literature by integrating institutional theory (INT) and dynamic capabilities (DC) to explore the interplay between CCER and MIER, GPRI-GPCI, sustainable marketing activities and STP.
