From resource variation to habitat loss: how changing environment shapes the plant-pollinator interactions
No full textAnnotation: Akter, A. and Klecka, J. 2020. Interactive effects of temperature, water, and nitrogen availability on the growth, floral traits, and pollination of white mustard, Sinapis alba. This was an experimental approach where Sinapis alba (white mustard), an economically beneficial crop was grown under different environmental conditions. Here, we assess how different growing conditions affected the growth of S. alba and the impact of different climate changing drivers on pollination and seed production. Akter, A., Biella, P., Klecka, J. 2017. Effects of small-scale clustering of flowers on pollinator foraging behaviour and flower visitation rate. PLoS ONE 12(11): e0187976. In this part of research, we experimentally changed the spatial structure of flower in small patches and assessed the impact on the foraging behaviour of pollinators, particularly, A. mellifera. Akter, A., Biella, P., Klecka, J. 2020. Introduction of new floral resources into plant-pollinator communities: impact on flower visitation mediated by species traits. This field-based experiment showed the impact of experimentally introduced floral resources in a plant community and how the response of the pollinator communities towards the new resources were mediated by the floral traits. Biella, P., Akter, A., Pajares, A.J.M., Federici, G., Galimberti, A., Jersáková, J., Labra, M., Mangili, F., Tommasi N. and Mangili, L. 2020. Pollination strategies of a plant in an unstable habitat: the case of the narrow-endemic toadflax Linaria tonzigii (Plantaginaceae). In this field-based research we assessed the pollination and reproduction strategies of an endemic plant, Linaria tonzigii, and the relation between the genetic variation and distribution.

Digital transformation of higher education in Australia: Understanding affordance dynamics in E-Textbook engagement and use
No full textThis paper addresses digital transformation in higher education by exploring the engagement and use of e-textbooks through an affordance theory lens. Drawing on the insights from in-depth interviews (n = 18), focus group discussions (n = 15), a pilot survey (n = 83) and the main survey (n = 344) in Australia, we developed and validated an affordance actualisation model for the engagement and use of e-textbooks. The partial least squares (PLS) technique was used to validate the dimensions of affordance actualisation and its relationship with e-textbooks engagement and affordance effect. The findings indicate the efficacy of the two affordance constructs, as well as the significant mediating effect of engagement. An important lesson for the e-textbook industry is that firms need to consider affordance actualisation dimensions (i.e., portability, accessibility, searchability, highlighting, copying, browsing, hedonic and utilitarian value) when enhancing digital engagement and use of e-textbooks

Observing Dynamic Conformational Changes within the Coiled-Coil Domain of Different Laminin Isoforms Using High-Speed Atomic Force Microscopy
No full textLaminins are trimeric glycoproteins with important roles in cell-matrix adhesion and tissue organization. The laminin alpha, ss, and gamma-chains have short N-terminal arms, while their C-termini are connected via a triple coiled-coil domain, giving the laminin molecule a well-characterized cross-shaped morphology as a result. The C-terminus of laminin alpha chains contains additional globular laminin G-like (LG) domains with important roles in mediating cell adhesion. Dynamic conformational changes of different laminin domains have been implicated in regulating laminin function, but so far have not been analyzed at the single-molecule level. High-speed atomic force microscopy (HS-AFM) is a unique tool for visualizing such dynamic conformational changes under physiological conditions at sub-second temporal resolution. After optimizing surface immobilization and imaging conditions, we characterized the ultrastructure of laminin-111 and laminin-332 using HS-AFM timelapse imaging. While laminin-111 features a stable S-shaped coiled-coil domain displaying little conformational rearrangement, laminin-332 coiled-coil domains undergo rapid switching between straight and bent conformations around a defined central molecular hinge. Complementing the experimental AFM data with AlphaFold-based coiled-coil structure prediction enabled us to pinpoint the position of the hinge region, as well as to identify potential molecular rearrangement processes permitting hinge flexibility. Coarse-grained molecular dynamics simulations provide further support for a spatially defined kinking mechanism in the laminin-332 coiled-coil domain. Finally, we observed the dynamic rearrangement of the C-terminal LG domains of laminin-111 and laminin-332, switching them between compact and open conformations. Thus, HS-AFM can directly visualize molecular rearrangement processes within different laminin isoforms and provide dynamic structural insight not available from other microscopy techniques
Modelling risk adaptation and mitigation behaviour under different climate change scenarios
No full textThe main objective of this study is to simulate household choice behavior under varying climate change scenarios using choice experiments. Economic welfare measures are derived for society’s willingness to pay (WTP) to reduce climate change induced flood risks through private insurance and willingness to accept compensation (WTAC) for controlled flooding under varying future risk exposure levels. Material flood damage and loss of life are covered in the insurance policy experiment, while the WTAC experiment also captures the economic value of immaterial flood damage such as feelings of discomfort, fear and social disruption. The results show that WTP and WTAC are substantial, suggesting a more prominent role of external social damage costs in cost-benefit analysis of climate change and flood mitigation policies
Revisiting business relationship quality in subsistence marketplaces
No full textMicro-entrepreneurs play a critical role in alleviating poverty in subsistence marketplaces through their business relationships with microfinance institutions. Despite the enormous importance of these relationships, a critical research question on the dimensions of business relationship quality and their overall effects on relationship outcomes remains unanswered. Thus, drawing on the relationship marketing, social exchange, and self-determination theories, this study answers the focal research question by conducting in-depth interviews (n = 30), thematic analysis, and a survey (n = 300) of micro-entrepreneurs in a subsistence marketplace. The findings show a third-order business relationship quality model with three second-order dimensions (i.e., business trust, business respect, and business reciprocity) and nine subdimensions. The findings confirm the impact of business relationship quality on business customer inspiration and business customer value examined in this marketplace. The findings also identify the mediating role of customer inspiration and both the moderating and quadratic roles of relationship quality on relationship outcomes. The predictive power of the business relationship quality model is validated through PLSpredict using a training sample (n = 270) and a holdout sample (n = 30)
How to Build an AI Climate-Driven Service Analytics Capability for Innovation and Performance in Industrial Markets?
No full textAI climate-driven service analytics capability has been anecdotally argued as a viable strategy to enhance service innovation and market performance in B2B markets. While AI climate refers to the shared perceptions of policies, procedures, and practices to support AI initiatives, cognitive service analytics capability refers to the analytical insights driven by AI climate and augmented by both machines and humans to make marketing decisions. However, there is limited knowledge on the antecedents of such analytics capabilities and their overall effects on service innovation and market performance. Drawing on service analytics literature and the microfoundations of dynamic capability theory, this study fills this research gap using in-depth interviews (n = 30) and a survey (n = 276) of service analytics managers within the AI climate in Australia. The findings confirm the five microfoundations of cognitive service analytics capabilities (cognitive technology, cognitive information, cognitive problem solving, cognitive knowledge & skills, cognitive training & development). The findings also highlight the significant mediating effect of service innovation in the relationship between analytics climate and market performance and cognitive service analytics capability and market performance
