Luxury rental operations are increasingly popular nowadays. In this study, we develop game-theoretical models to examine the optimal renter's integration strategies (RISs) in a luxury supply chain with conspicuous consumers. The luxury supply chain consists of one manufacturer, one seller and one renter. Based on observed industrial practices, we compare three RISs, namely non-integration (the renter works on his own), vertical integration (the renter operates with the manufacturer) and horizontal integration (the renter co-operates with the seller). The main findings are as follows. First, integration is not always a wise strategy for the renter. When the proportion of conspicuous consumers (PCC) is sufficiently high, the renter should work on his own. When the PCC is lower than a threshold, the optimal RIS depends on the trade-off between the double-marginalisation and retail competition effects. Second, we evaluate the environmental impacts of RISs and uncover that the environmental effects depend on the product types' environmental impact. We further identify the conditions how a dominating situation with respect to profitability and environmental impact can be achieved (called 'PE dominating'). Third, we investigate the effects of consumer segmentation on the optimal RIS. Managerial implications are discussed. [ABSTRACT FROM AUTHOR]

SUMMARY: Moving from sole cropping to intercropping is a transformative change in agriculture, contributing to yield. Soybeans adapt to light conditions in intercropping by adjusting the onset of reproduction and the inflorescence architecture to optimize reproductive success. Maize–soybean strip intercropping (MS), maize–soybean relay strip intercropping (IS), and sole soybean (SS) systems are typical soybean planting systems with significant differences in light environments during growth periods. To elucidate the effect of changes in the light environment on soybean flowering processes and provide a theoretical basis for selecting suitable varieties in various planting systems to improve yields, field experiments combining planting systems (IS, MS, and SS) and soybean varieties (GQ8, GX7, ND25, and NN996) were conducted in 2021 and 2022. Results showed that growth recovery in the IS resulted in a balance in the expression of TERMINAL FLOWER 1 (TFL1) and FLOWERING LOCUS T (FT) in the meristematic tissues of soybeans, which promoted the formation of new branches or flowers. IS prolonged the flowering time (2–7 days) and increased the number of forming flowers compared with SS (93.0 and 169%) and MS (67.3 and 103.3%) at the later soybean flowering stage. The higher carbon and nitrogen content in the middle and bottom canopies of soybean contributed to decreased flower abscission by 26.7 and 30.2%, respectively, compared with SS. Canopy light environment recovery promoted branch and flower formation and transformation of flowers into pods with lower flower‐pod abscission, which contributed to elevating soybean yields in late‐maturing and multibranching varieties (ND25) in IS.

The biological clock (also known as circadian clock) is closely related to growth and development, metabolism, and diseases in animals. As a part of the circadian clock, the cryptochrome circadian regulator 1 (CRY1) gene is involved in the regulation of biological processes such as osteogenesis, energy metabolism and cell proliferation, however, few studies have been reported on the relationship between this gene and animal carcass traits. Herein, a total of four insertion/deletion (InDel) loci within the CRY1 gene were detected in Shandong Black Cattle Genetic Resource (SDBCGR) population (n = 433). Among them, the P1-6-bp-del locus was polymorphic in population of interest. Moreover, the P1-6-bp-del locus showed two genotypes, with a higher insertion/insertion (II) genotype frequency (0.751) than insertion/deletion (ID) genotype frequency (0.249). Correlation analysis showed that the P1-6-bp-del locus polymorphisms were significantly associated with twenty carcass traits (e.g., slaughter weight, limb weight, and belly meat weight). Individuals with II genotype were significantly better than those with ID genotype for eighteen carcass traits. Therefore, the P1-6-bp-del locus of the CRY1 gene can be used as a molecular marker for beef cattle breeding. [ABSTRACT FROM AUTHOR]
