Purpose
This study aims to propose guidelines for the joint use of partial least squares structural equation modeling (PLS-SEM) and fuzzy-set qualitative comparative analysis (fsQCA) to combine ...symmetric and asymmetric perspectives in model evaluation, in the hospitality and tourism field.
Design/methodology/approach
This study discusses PLS-SEM as a symmetric approach and fsQCA as an asymmetric approach to analyze structural and configurational models. It presents guidelines to conduct an fsQCA based on latent construct scores drawn from PLS-SEM, to assess how configurations of exogenous constructs produce a specific outcome in an endogenous construct.
Findings
This research highlights the advantages of combining PLS-SEM and fsQCA to analyze the causal effects of antecedents (i.e., exogenous constructs) on outcomes (i.e., endogenous constructs). The construct scores extracted from the PLS-SEM analysis of a nomological network of constructs provide accurate input for performing fsQCA to identify the sufficient configurations required to predict the outcome(s). Complementing the assessment of the model’s explanatory and predictive power, the fsQCA generates more fine-grained insights into variable relationships, thereby offering the means to reach better managerial conclusions.
Originality/value
The application of PLS-SEM and fsQCA as separate prediction-oriented methods has increased notably in recent years. However, in the absence of clear guidelines, studies applied the methods inconsistently, giving researchers little direction on how to best apply PLS-SEM and fsQCA in tandem. To address this concern, this study provides guidelines for the joint use of PLS-SEM and fsQCA.
Generative models are used as an alternative data augmentation technique to alleviate the data scarcity problem faced in the medical imaging field. Diffusion models have gathered special attention ...due to their innovative generation approach, the high quality of the generated images, and their relatively less complex training process compared with Generative Adversarial Networks. Still, the implementation of such models in the medical domain remains at an early stage. In this work, we propose exploring the use of diffusion models for the generation of high-quality, full-field digital mammograms using state-of-the-art conditional diffusion pipelines. Additionally, we propose using stable diffusion models for the inpainting of synthetic mass-like lesions on healthy mammograms. We introduce MAM-E, a pipeline of generative models for high-quality mammography synthesis controlled by a text prompt and capable of generating synthetic mass-like lesions on specific regions of the breast. Finally, we provide quantitative and qualitative assessment of the generated images and easy-to-use graphical user interfaces for mammography synthesis.
This paper studies both Formula omittedCDM and CDM models under the über gravity theory, named ü Formula omittedCDM and üCDM respectively. We report bounds over their parameter phase-space using ...several cosmological data, in particular, the recent Pantheon+ sample. Based on the joint analysis, the best fit value of the über characteristic parameter is Formula omitted and Formula omitted at 68% confidence level for ü Formula omittedCDM and üCDM respectively. Although über gravity can successfully mimics the cosmological constant, we find that the Formula omitted diagnostic suggests the Formula omitted tension is not alleviated. Finally, both models are statistically compared with Formula omittedCDM through the Akaike and Bayesian information criteria. Both über gravity models and Formula omittedCDM are equally preferred for most of the single samples, in particular, ü Formula omittedCDM is not rejected by the CMB data. However, there is strong evidence against them for the joint analysis.

The increasing interest in fuzzy-set Qualitative Comparative Analysis (fsQCA) in Information Systems and marketing raises the need for a tutorial paper that discusses the basic concepts and principles of the method, provide answers to typical questions that editors, reviewers, and authors would have when dealing with a new tool of analysis, and practically guide researchers on how to employ fsQCA. This article helps the reader to gain richer information from their data and understand the importance of avoiding shallow information‐from‐data reporting. To this end, it proposes a different research paradigm that includes asymmetric, configurational‐focused case‐outcome theory construction and somewhat precise outcome testing. This article offers a detailed step-by-step guide on how to employ fsQCA by using as an example an already published study. We analyze the same dataset and present all the details in each step of the analysis to guide the reader onto how to employ fsQCA. The article discusses differences between fsQCA and variance-based approaches and compares fsQCA with those from structured equation modelling. Finally, the article offers a summary of thresholds and guidelines for practice, along with a discussion on how existing papers that employ variance-based methods are extendable and complemented through fsQCA.
The critical issue of high resistance at the interface between cathode and solid electrolyte for creating all-solid-state power sources can be addressed by introducing a low-melting additive ...(Li.sub.3BO.sub.3) and lithium-conducting solid electrolyte (Li.sub.7La.sub.3Zr.sub.2O.sub.12) in the LiNi.sub.1/3Co.sub.1/3Mn.sub.1/3O.sub.2 cathode mass. The chemical and thermal stability of the solid electrolyte in contact with LiNi.sub.1/3Co.sub.1/3Mn.sub.1/3O.sub.2 and Li.sub.3BO.sub.3 was studied using XRD and DSC analysis. It was found that the introduction of 5 wt% Li.sub.3BO.sub.3 in LiNi.sub.1/3Co.sub.1/3Mn.sub.1/3O.sub.2 leads to a close contact between the solid electrolyte and cathode and a decrease in the interfacial resistance from 45000 to 85 Omega cm.sup.2 at 300 °C compared to pure LiNi.sub.1/3Co.sub.1/3Mn.sub.1/3O.sub.2. The addition of 5 wt% lithium-conductive electrolyte to the cathode mass does not lead to significant changes in interface resistance. No degradation processes in the components of the experimental cell with composite cathode and Li anode were found during electrochemical experiments.
Abstract The analysis of the time profile of electrical signals produced by energy depositions in germanium detectors allows discrimination of events with different topologies. This is especially ...relevant for experiments searching for the neutrinoless double beta decay of $$^{76}$$ 76 Ge to distinguish the sought-after signal from other background sources. The standard calibration procedures used to tune the selection criteria for double-beta decay events use a $$^{228}$$ 228 Th source, because it provides samples of signal-like events. These samples exhibit energy spatial distributions with subtle different topologies compared to neutrinoless double-beta decay events. In this work, we will characterize these topological differences and, with the support of a $$^{56}$$ 56 Co source, evaluate biases and precision of calibration techniques which use such event samples. Our results will be particularly relevant for future experiments in which a solid estimation of the efficiency is required.
