PurposeThis study examines the impact of transactive memory systems, conceptualized as organizational knowledge-based systems, on network capability and firm performance, with a focus on the mediating role of technology adaptive capability. To achieve this, the study integrates transactive memory systems, relational view, and dynamic capabilities.Design/methodology/approachData collected from 935 firms operating in T & uuml;rkiye were analyzed using partial least squares structural equation modeling (PLS-SEM) with SmartPLS 4 to assess the measurement model, test the structural relationships, and evaluate both explanatory power and predictive relevance.FindingsThe findings indicate that transactive memory systems have a direct positive effect on network capability, technology adaptive capability, and firm performance. Network capability positively influences technology adaptive capability and firm performance, while technology adaptive capability strongly enhances firm performance. Furthermore, network capability and technology adaptive capability both individually and sequentially mediate the relationship between transactive memory systems and firm performance, highlighting their critical role in translating collective knowledge into adaptive capabilities that improve organizational outcomes.Originality/valueThis study is one of the first to conceptualize transactive memory systems as an organizational knowledge-based system and to test its effect on firm performance through network capability and technology adaptive capability within a multi-level model.
Land-use change is a critical driver reshaping aeroecological patterns in semiarid ecotones worldwide. Understanding these dynamics is essential as global biodiversity loss projections suggest that Mediterranean ecosystems are increasingly vulnerable. This study comparatively analyses the aeroecological signatures of two contrasting land-use models (urban and agricultural) within a semiarid ecotone in Southeastern Türkiye. We propose the “Aeroecological Paradox” as a conceptual framework to describe the structural divergence between these landscape types. Atmospheric pollen data from Gaziantep (2010–2011; urban) and Kilis (2018–2019; agricultural) were analysed using a space-for-time substitution approach to assess land-use effects within comparable ecological settings. Moving from the urban landscape (Gaziantep) to the agricultural landscape (Kilis), total pollen load decreased by 76
The genotype-level compositional stability of essential oil (EO) chemotype expression in basil (Ocimum basilicum L.) is critical for industrial quality assurance and may also be relevant for preliminary food safety screening, yet remains poorly characterised across the environmental variation encountered in production. This study characterises the environmental modulation of EO yield and chemotype composition in a pre-selected panel of 12 basil genotypes representing four chemotypes (linalool, estragole, citral, and methyl cinnamate) using a three-layer experimental design: (i) ecological variation across three contrasting Turkish locations (Bursa, Eskişehir, Tokat) over two years, (ii) ontogenetic variation across three developmental stages at Bursa, and (iii) seasonal variation between summer and autumn harvests at Tokat (144 unique EO profiles). EO yield was highest at Bursa (0.98 mL·100 g⁻1 dry weight). At Bursa, EO yield increased from pre-flowering to onset of flowering, whereas at Tokat, autumn harvests produced higher yields than summer harvests. Genotype R-10A, representing the estragole chemotype, showed very high genotype-specific compositional stability under the tested ecological conditions (Layer 1 CV = 2.8
Normocalcemic primary hyperparathyroidism (NPHPT) is thought to be an early form of hypercalcemic primary hyperparathyroidism (PHPT). However, some studies have shown that the adverse effects on bone and kidney health are similar in both conditions. This is a nationwide, multicentre, retrospective study. Data from centres, including 404 patients with NPHPT and 723 patients with mild PHPT from different regions of Turkey, were included in this study. All laboratory parameters, dual-energy X-ray absorptiometry, and renal ultrasounds were performed locally at each centre. The prevalence of adverse bone and kidney outcomes and metabolic and cardiovascular comorbidities were the main outcome measures. Patients with NPHPT had lower calcium and PTH levels. Skeletal outcomes revealed 29
Basil (Ocimum basilicum L.) is a globally consumed herb whose hydroxycinnamic acid esters and flavonoids contribute to dietary antioxidant intake. This study aimed to characterise the phenolic composition, antioxidant capacity, and developmental-stage variability of twelve Turkish basil genotypes grown across three ecologically contrasting sites. Twelve genotypes were evaluated in a two-year field experiment (Year 1 and Year 2) at three ecologically contrasting locations in Türkiye: Bursa, Eskişehir, and Tokat. Agronomic performance, nine-compound HPLC–TOF phenolic profiles (Year 1), total phenolic content (TPC), and antioxidant capacity (ABTS, DPPH, and FRAP) were measured. The effects of developmental stage on the phenolic composition of plants from Bursa (Year 1) were characterised. Location was the dominant source of variation in phenolic quality. Plants from Tokat ranked highest for individual phenolic concentrations (Year 1 HPLC–TOF data) and for all three antioxidant assays (two-year means). Rosmarinic acid varied 4.4-fold (59.0–261.8 mg 100 g⁻¹ DW; Year 1), with the highest values recorded for genotypes R-3k, R-19, R-15, and R-4 from Tokat. ABTS antioxidant capacity was 113
