Abstract
In today's world, the idea of sustainable fashion is gaining traction. Finding a link between pricing and the purchase of sustainable clothes is the aim of this study. Regression models and t-tests of two independent samples (two-tailed tests) were applied by means of the application of a questionnaire. The study found that consumers' willingness to pay for price increases is related with non-linear (quadratic or exponential) product pricing. The results of this study suggest that consumers are willing to pay higher prices for sustainable clothing. Through an understanding of the relationship between price and consumer behavior, businesses can more effectively align their pricing strategies with the demands of environmentally conscious consumers. © 2024, IGI Global.

Abstract
In this letter, we introduce the computation-limited (comp-limited) signals, a communication capacity regime where the computational complexity of signal processing is the primary constraint for communication performance, overriding factors such as power or bandwidth. We present the Spectro-Computational (SC) analysis, a novel mathematical framework designed to enhance classic concepts of information theory -such as data rate, spectral efficiency, and capacity - to accommodate the computational complexity overhead of signal processing. We explore a specific Shannon regime where capacity is expected to increase indefinitely with channel resources. However, we identify conditions under which the time complexity overhead can cause capacity to decrease rather than increase, leading to the definition of the comp-limited signal regime. Furthermore, we provide examples of SC analysis and demonstrate that the Orthogonal Frequency Division Multiplexing (OFDM) waveform falls under the comp-limited regime unless the lower-bound computational complexity of the N-point Discrete Fourier Transform (DFT) problem verifies as ohm (N)$ , which remains an open challenge in the theory of computation.

Abstract
The congress which ISPGAYA organized in Vila Nova de Gaia, Portugal, on 26 and 27 October 2023 is based on the theme of sustainability, meeting the current academic, social, and political agenda. The congress is based on the theme of digital sustainability, meeting the current academic, social, and political agenda. This event brings together the different scientific areas of ISPGAYA and seeks to highlight the set of interdisciplinary and multilevel efforts to change the existing reality, supported by the affinity of ideas and attitudes, knowledge, and practices. Contributions from different institutions, national and international, that make up the technological and scientific system, asserting the concertation of strategies at local, regional, and global levels, and the interconnection between synergistic contributions of the living forces to mobilize toward to consolidate planetary sustainability over the next few decades. The scope of this book comprehends manuscripts submitted under the various thematic: Industrial Automation; Energy Efficiency; Information Technology & Cybersecurity; Management & Administration; Marketing; Tourism & Leisure; Education. All these scientific areas are connected by the main issue sustainability. Researchers, professionals, and students from different areas participate in this sharing of knowledge, suggesting a reticular logic and partnerships in the approach to sustainability. The publication of this book of proceedings intends to increase and dynamize investigation linking theory and practice, always pointing to innovative approaches, and mainly, involve as many people and institutions as possible in the direction of a smart national and global development model, meeting the intentions of the 2030 agenda outlined by the United Nations. We lift the veil on responsible innovation including technology innovation and entrepreneurship toward innovation for sustainable development and make positive impact in the ongoing paradigm shift from a same development model to building a safe operating space for a SMART Earth3 model, comprising Local Sustainable Development Goals.

Abstract
Narratives have been the subject of extensive research across various scientific fields such as linguistics and computer science. However, the scarcity of freely available datasets, essential for studying this genre, remains a significant obstacle. Furthermore, datasets annotated with narratives components and their morphosyntactic and semantic information are even scarcer. To address this gap, we developed the Text2Story Lusa datasets, which consist of a collection of news articles in European Portuguese. The first datasets consists of 357 news articles and the second dataset comprises a subset of 117 manually densely annotated articles, totaling over 50 thousand individual annotations. By focusing on texts with substantial narrative elements, we aim to provide a valuable resource for studying narrative structures in European Portuguese news articles. On the one hand, the first dataset provides researchers with data to study narratives from various perspectives. On the other hand, the annotated dataset facilitates research in information extraction and related tasks, particularly in the context of narrative extraction pipelines. Both datasets are made available adhering to FAIR principles, thereby enhancing their utility within the research community.

Abstract
The adoption of open innovation poses significant challenges that are important to explore. Studies in this field have mainly focused on exploring the causes of the failure of open innovation among large companies. This study addresses this research gap by employing a sample of 297 Portuguese small- and medium-sized enterprises (SMEs) to explore, through a quantitative study, whether the dimensions and causes of failure differ between large organizations and SMEs. A total of seven dimensions of causes of failure are considered, including strategy-related, organizational structure, organizational culture, knowledge and intellectual property management, management skill and action, resources, and interfirm collaboration. The findings reveal significant differences in four of these seven dimensions: the main causes of failure are related to the resources and management processes of open innovation in SMEs, while large companies face more challenges in the organizational structure and culture components. This study offers theoretical insights into the gaps in the literature to better understand the challenges facing open innovation. Furthermore, this study offers practical guidelines for SMEs to identify and mitigate these main obstacles, promoting better innovation management practices.

Abstract
X-Wing is a hybrid key-encapsulation mechanism based on X25519 and ML-KEM-768. It is designed to be the sensible choice for most applications. The concrete choice of X25519 and ML-KEM-768 allows X-Wing to achieve improved efficiency compared to using a generic KEM combiner. In this paper, we introduce the X-Wing hybrid KEM construction and provide a proof of security. We show (1) that X-Wing is a classically IND-CCA secure KEM if the strong Diffie-Hellman assumption holds in the X25519 nominal group, and (2) that X-Wing is a post-quantum IND-CCA secure KEM if ML-KEM-768 is itself an IND-CCA secure KEM and SHA3-256 is secure when used as a pseudorandom function. The first result is proved in the ROM, whereas the second one holds in the standard model. Loosely speaking, this means X-Wing is secure if either X25519 or ML-KEM-768 is secure. We stress that these security guarantees and optimizations are only possible due to the concrete choices that were made, and it may not apply in the general case.
