Summary: Despite being completed over eight years ago, the use of data from the GOCE mission still provides valuable insights into Earth system processes. GeoGravGOCE is an open-source software, developed in MATLAB, that offers a user-friendly GUI to process the original GOCE gradiometric observations. It provides various functionalities, such as gradient pre-processing, coordinate transformation, and filtering. Three filtering methods are implemented within the software, allowing users to select the desired level of filtering and evaluate the results.

Summary: This study evaluates the applicability of different filters to the error characteristics in observation data from the GOCE satellite. The cascade filter (DARMA) shows the best accuracy for the 1/f low-frequency error. The strategy of introducing empirical parameters reduces orbital frequency errors, while using a notch filter worsens the final solution.

Summary: The West and Central African Rift System is a unique stable continental structure formed by large-scale topographic swells. Through the use of global gravitational and topographic-bathymetric models, researchers were able to determine the crustal structure and Moho depth variations in different regions of the WCARS. The findings also shed light on metacratonization processes that occurred during the Neoproterozoic.

Summary: The development of a parallel algorithm that combines MPI and OpenMP programming models has greatly improved the efficiency of calculating high-degree/order gravity field models. By utilizing the symmetrical feature of normal equations, the calculation time for generating the normal equation of a degree/order 240 model was significantly reduced. Additionally, modifications were made to the MPI parallel Gaussian-Jordan elimination method, allowing for matrix inversion on a larger number of processor cores.

Summary: The new gravity field models of GOCE, TIM_R6 and DIR_R6, released by ESA in June 2019, show improved accuracy and signal levels compared to previous models, providing opportunities for high precision geostrophic currents. Results indicate that geostrophic currents obtained from GOCE models better reflect detailed ocean current characteristics. After applying the remove-restore technique to TIM_R6 MDT, the total geostrophic speeds showed a significant decrease in standard deviation, demonstrating improved accuracy.

Summary: The study focused on the Aegean Graben System in western Turkey, using differential evolution algorithm (DEA) to invert the depths of sediment cover-metamorphic basement. Parameterization was done through discretizing the basins into vertical blocks, and mathematical nature of the inverse problem was explored. Both synthetic and field data inversions showed that the maximum depths to the metamorphic basement reliefs in the grabens are shallower than previous findings, with the sediment thicknesses resolvable.

Summary: This paper examines the factors influencing the willingness of Bangladeshi farmers to adopt and pay for the Internet of Things (IoT) in the agricultural sector. The study finds that several factors, such as effort expectancy, performance expectancy, facilitating condition, hedonic motivation, government support, price value, personal innovativeness, and trust, influence the adoption of IoT by Bangladeshi farmers. The study also reveals that trust and willingness to adopt affect the willingness to pay for the IoT. In addition, the study highlights the moderating role of willingness to adopt in the relationship between performance expectancy, price value, and willingness to pay for the IoT. This research has implications for marketers of IoT technology in rural areas, as it provides insights into the reasons for the adoption of IoT in agriculture and informs the design of appropriate marketing strategies.

Summary: Botswana, a country with low seismic activity, experienced an unexpected 6.5 magnitude earthquake in April 2017. Through the analysis of seismic network data, two areas of elevated seismic activity were identified: the Okavango Rift Zone in northern Botswana and the central region associated with the 2017 mainshock and its aftershocks. The mainshock and aftershocks occurred along reactivated fault systems, with the aftershocks happening at shallower depths than the mainshock.

Summary: Drawing upon the natural-resource-based view (NRBV), this study examines the impact of environmental strategy (ENS) and environmental awareness (ENA) on firms' environmental and financial performance. The study finds that ENS significantly affects organizational competitive advantage and environmental performance, while ENA significantly affects competitive advantage, and environmental and financial performance. Competitive advantage mediates the relationships between ENS and environmental performance, as well as between ENA and environmental performance. However, ENS has an insignificant effect on firms' financial performance.

Summary: Many countries have adopted the circular economy as an effective solution for sustainable development, balancing economic progress, environmental preservation, and social protection. This study examines the role of green logistics and green human capital in promoting a circular economy, with sustainable production as a mediator. Data from 211 garment manufacturing firms in Bangladesh were analyzed using PLS-SEM. The findings show that green logistics and green human capital are significant drivers of the circular economy, with a positive impact on sustainable production. Sustainable production also positively influences the implementation of the circular economy, mediating the relationships between green logistics and the circular economy, as well as between green human capital and the circular economy. This study adds critical insights to theory and practice, providing theoretical and managerial implications.

Summary: The study aims to identify the factors influencing the online fast food-buying intention among Bangladeshi Millennials during the COVID-19 pandemic. The study adopts the Value-Attitude-Behavior (VAB) model and designs it as a higher-order constructs model to predict buying intention. The findings reveal that convenience and food quality generate utilitarian values, while subjective norms and novelty-seeking form hedonic values. Utilitarian and hedonic values significantly affect cognitive and affective attitudes. Contrary to food quality, cognitive attitude, affective attitude, self-identity, and subjective norms were found to influence behavioral intention, with affective attitude being the strongest predictor, although the model has a high explanatory power.
