The Dollar's Double Life: Not All Dollar Appreciations Are Born Equal for the Cross-Currency Basis
Full text linkThis paper revisits the relationship between the US dollar and cross-currency basis (XCB) swap spreads. We show that the strength and direction of this relationship depend on the prevailing regime of the broad dollar. The evidence suggests that the well-documented “dollar appreciates, basis widens” result holds primarily when the dollar is in a low or intermediate regime. However, once the dollar transitions into a high regime, this association either weakens or reverses: a stronger dollar no longer widens the basis and may tighten it. Our findings reveal that not all dollar appreciations are created equal. For the same magnitude of dollar appreciation, basis spreads tend to widen significantly more in low- or intermediate-dollar regimes than in high-dollar regimes. We explain these results through a theoretical framework grounded in hedging demand and supply imbalances and validate them empirically using the term structure of XCB swap spreads of G10 currencies
New Constructions of Asymptotically Optimal Zero/Low Ambiguity Zone Sequence Sets
Full text linkSequences exhibiting zero/low ambiguity zone (ZAZ/LAZ) properties play an important role in contemporary communication and radar systems, particularly in Integrated Sensing and Communication (ISAC), which is an emerging wireless technology by sharing the hardware and bandwidth to perform these two tasks simultaneously. By incorporating nonlinear mapping and parity adaptive factor to design novel exponential functions, this letter proposes three methods for constructing ZAZ/LAZ sequence sets with new parameters. The resulting sequences are cyclically distinct and asymptotically optimal with respect to theoretical bounds
Enhancing Supply Chain Agility and Performance through Big Data Analytics: The Role of Digitalization and Top Management Support
No full textPurpose: This study aims to examine the relationships between big data analytics capabilities (BAC), supply chain digitalization (SCD), supply chain agility (SCA), and supply chain performance (SCP), while assessing the moderating role of top management support (TMS) in these relationships. It seeks to advance understanding of how digital transformation and leadership support enhance supply chain agility and performance outcomes.
Design/methodology/approach: This study applies regression modeling to survey data collected from manufacturing firms. The model examines the direct effects of BAC on SCA and SCP, while assessing the mediating role of SCA and the moderating influence of SCD and TMS. The analysis also explores how these relationships contribute to sustainable supply chain performance outcomes.
Findings: The results demonstrate that BAC positively influences SCA, which in turn enhances SCP. SCD amplifies the effect of BAC on SCA, while TMS significantly moderates the relationships between SCD and both BAC-SCA and SCA-SCP. These findings suggest that digital technologies and leadership support jointly drive supply chain agility and performance in dynamic business environments.
Originality/value: This study contributes to supply chain management literature by integrating BAC, SCD, and TMS into a comprehensive framework that elucidates their combined effects on agility and performance. It highlights the strategic importance of digital transformation and top management support in fostering agile and high-performing supply chains, offering actionable insights for managers and policymakers
This business is mine! Intra-household effects of property rights in micro-enterprises
No full textThis paper studies the intra-household impact of property rights in micro-enterprises. A randomized field experiment on firm formalization in Benin provides exogenous variation in individual property rights. The results reveal significant gender differences. Women entrepreneurs who formalize invest more in their businesses and are more likely to pay to conceal a large windfall transfer from their husbands—a measure of intra-household inefficiency. These findings suggest that while stronger property rights secure and incentivize investment, they may also reduce household cooperation, leading to efficiency losses. Despite this trade-off, women report higher overall well-being when granted formal property rights. In contrast, formalization improves intra-household efficiency for men, likely by reinforcing their authority over household decision-making. Consistently, male entrepreneurs who formalize are more likely to separate business and household finances and to resist pressure to share resources
Materiality assessment and interconnectedness of sustainable development goals: uncovering misalignments between corporate and stakeholder priorities
Full text linkPurpose Companies are encouraged to proactively identify and address the sustainability issues most relevant to stakeholders and respond to their concerns and expectations. This paper aims to examine how materiality assessment and the interconnectedness of Sustainable Development Goals (SDGs) can help uncover misalignments between corporate sustainability priorities and stakeholder expectations.
Design/methodology/approach The authors focus on Nestlé as a case study, analyzing its sustainability reports alongside stakeholder discussions on Twitter. Nestlé’s SDG-related disclosures were used to construct a materiality matrix, while stakeholder communications were manually coded. The authors then compared the constructed matrix with Nestlé’s own materiality matrix provided in its sustainability report. In addition, the authors conducted social network analysis to explore the interconnectedness of SDGs as portrayed in Nestlé’s sustainability report and reflected in stakeholder discussions on Twitter.
Findings The study reveals misalignments between Nestlé’s sustainability report and stakeholders’ sustainability concerns expressed on social media. For example, while both Nestlé and stakeholders recognize the importance of SDG 12 Responsible Consumption and Production, stakeholders place greater emphasis on SDG 6 Clean Water and Sanitation than the company’s matrix suggests. Social network analysis of SDG interconnectedness further highlights distinct perspectives between Nestlé and its stakeholders, with SDG 12 emerging as a central theme.
Practical implications When developing their methodologies for materiality assessment, companies should consider using various sources of information, including social media. Furthermore, interconnectedness analysis can help uncover misalignments between corporate and stakeholder priorities. Finally, materiality assessment may be more effective and credible when conducted independently from a third party.
Social implications Achieving the SDGs requires coordination, collaboration, and effective reporting. Our findings suggest that misalignments between corporate materiality assessments and stakeholder priorities may weaken public trust and limit meaningful progress toward the SDGs. Incorporating stakeholder perspectives–particularly those expressed through social media–can support more inclusive sustainability governance, enhance transparency, and promote more coherent action across interconnected SDGs
Originality/value This study contributes new insights into the use of materiality assessment and SDG interconnectedness to reduce misalignments between corporate and stakeholder SDG priorities. It demonstrates the value of alternative data sources, particularly social media, in supporting materiality assessments and SDG interconnectedness analysis. Moreover, it illustrates how stakeholder discussions on social media and social network analysis can be used to examine the interconnections among SDGs as perceived by both companies and stakeholders
The psychological impact of adult-onset craniopharyngioma: A follow-up survey
Full text linkPurpose Adult-onset craniopharyngioma (AoC) is a rare benign tumour of the sellar/parasellar region associated with significant physical morbidity and a poorer quality of life. Limited medical studies have documented the psychological impact of AoC, but psychological studies may be better placed to investigate these effects. This study used an exploratory sequential mixed-methods design to develop and administer a new patient-informed survey to quantitatively assess the psychosocial consequences of AoC.
Methods A 30-item questionnaire was developed based on previous qualitative interviews with AoC patients and clinicians. Items covered psychological and physical impacts, including mood, social functioning, and emotion regulation. Participants (N = 25) were recruited online via a UK-based charity and completed the survey through Qualtrics. Percentage endorsements were calculated for each item, and regression analyses examined associations with individual history.
Results There was a clear psychosocial impact of AoC: 88% reported low mood, 68% felt they no longer recognized themselves, and 56% missed social events due to anxiety. Physical symptoms were also prominent, but importantly these were associated with significant psychosocial implications. Finally, growth hormone replacement therapy was significantly associated with reduced physical impact.
Conclusion Findings demonstrate a significant psychosocial impact of AoC, highlighting the importance of integrated mental health care in its management and the need for further psychosocial research to improve quality of life for patients
A Lightweight Multimodal Fusion Method for Object Detection Based on Bird’s Eye View
Full text linkThis article proposes a lightweight multimodal fusion object detection algorithm based on bird’s eye view (BEV) perception, addressing the challenges of high computational complexity and insufficient feature fusion when integrating camera and light detection and ranging (LiDAR) data in autonomous vehicles. To alleviate the computational burden, depthwise separable convolution and large separable kernel attention (LSKA) are introduced, constructing a lightweight feature extraction network that effectively captures features from camera data. To enhance computational efficiency, a parallel-optimized BEV pooling structure is proposed that improves the computation process and memory access patterns. In the feature fusion stage, a novel dualmodality dual-attention feature fusion module is designed that integrates the features from both modalities using parallel channel attention and spatial attention mechanisms to strengthen correlations between multimodal features. In addition, a weight generation network is introduced to adaptively assign fusion weights to features of the two modalities. The proposed algorithm has a lightweight structure and achieves cross-modal feature alignment in the BEV space. The experimental results of the public nuScenes dataset show that the proposed algorithm achieves an mAP of 0.682 and a normalized discounted success (NDS) of 0.710, while maintaining detection accuracy similar to the baseline model. Furthermore, the algorithm reduces the computational load from 253.2 to 202.3 G MACs, approximately a 20% decrease, and improves the inference speed from 8.4 to 10.0 FPS. Furthermore, our algorithm has also been experimentally validated on theWaymo dataset, demonstrating performance comparable to that of the BEVFusion method. These results demonstrate significant improvements in both computational efficiency and deployment-friendliness while preserving detection performance
The performance, health and development of youth women's footballers: a systematic scoping review
Full text linkThe primary aim of this scoping review was to summarise the current scientific literature on the performance, health and development of youth women’s footballers. The review provides a summary of the research topics, including methodological approaches adopted and key findings, and identifies gaps in the literature. A systematic search of electronic databases was conducted in December 2023 and June 2025, with keywords relating to the population, football, and performance, health and development. Studies which involved youth women’s footballers playing at any competitive standard, and quantified at least one aspect of performance, health or development were included. Of the 16,473 studies identified in the database searches, 294 studies met the eligibility criteria to be included in the review. Of the eight research topics investigating the performance, health and development of youth women’s footballers, physical qualities was the most investigated (n=119; 40%), followed by injury (n=49; 17%), biomechanics (n=40; 14%), psychology (n=31; 11%), match-play (n=20; 7%), nutrition (n=14; 5%), fatigue and recovery (n=13; 4%) and training load (n=8; 3%). Players competing in regional (42%) and national competitions (32%), and within an U17 age-group (23%) were the most investigated. Over half of all studies (56%) were published from 2020 onwards, demonstrating recent rapid growth in youth women’s football literature. This comprehensive resource can be used to inform practices supporting the performance, health and development of youth women’s footballers across various competitive standards. Furthermore, multiple research areas are highlighted as underdeveloped, and areas for future research concerning this population to explore
The web of perception: reinterpreting Duchamp’s ‘Mile of String’ in <i>First Papers of Surrealism</i>
Full text linkIn 1942, a group of Surrealist artists led by André Breton—then living in exile following the Nazi occupation of Western Europe—organised the first Surrealist exhibition in the United States. Entitled First Papers of Surrealism, the exhibition presented works by more than thirty artists, including objects then categorised as ‘primitive art'. Marcel Duchamp's installation was one of the most daring exhibitions of the early 20th century, installing the entire gallery space with his so‐called ‘Mile of String'. This web‐like structure by Duchamp not only gave Breton and the Surrealists a scandalous success that exceeded their expectations but also almost completely wiped out the visibility of some of their works that should have attracted attention. The string in this exhibition has often been discussed as a barrier, as T.J. Demo called it ‘the greatest obstacle between the painting and the viewing space'. This essay aims to reassess prevailing interpretations by examining ‘Mile of String' as a transparent medium that reconfigured the dynamics of spectatorship. In this light, the discussion situates Duchamp’s installation within broader Surrealist exhibition strategies, demonstrating how it invited spectators to engage critically and imaginatively with art beyond conventional dualisms
