Reliability and validity of the Japanese version of the Sleep Problem Acceptance Questionnaire

This study aimed to develop a Japanese version of the Sleep Problem Acceptance Questionnaire (SPAQ-J) and assess its reliability and validity. The SPAQ-J was developed through a forward-backward translation procedure with permission from the original authors. The sample included...

Ceramic districts as a landscape of practice: a case study of knowledge sharing in Japan

This study examines how a landscape of practice (LoP) influences learning activities within its constituent communities of practice (CoPs), focusing on how individuals navigate both enhancing and inhibiting factors. Using a qualitative case study approach, we investigated four ce...

How Gender Bias Shapes Promotion Aspirations

ABSTRACT This study examines the relationship between employees' gender biases, defined as the belief that men are better suited for managerial positions than women are, and promotion aspirations using online survey data ( N = 939). Probit and instrumental variables approaches ar...

Confrontation, cooperation, and perceived ideology: experimental research on voters’ perceived positions and political competition

Abstract Accurate perceptions of parties’ political positions are necessary for accountability and representation. Politicians signal their political positions to voters through policy messages; however, policy messages alone often do not work as intended. Furthermore, since poli...

How β -Ionone Ring Dynamics and Conformational Heterogeneity Control Carotenoid Photophysics

Abstract Carotenoid ultrafast photophysics has been studied for decades, but fully resolving their excited-state relaxation mechanisms remains a central, driving pursuit. Here, we investigate mini-β-carotene (m5) as a tractable model system, coupling high time-resolution transien...

Impact of Integrated Reports on Cost of Equity: Evidence From Japanese Listed Firms

ABSTRACT This study empirically analyzes the effects of the voluntary adoption and quality of integrated reports (IRs) on the cost of equity capital in Japan. Using 514 Tokyo Stock Exchange listed firms (over 2004–2020) and employing propensity score matching, difference‐in‐diffe...

Facet Numbers of Non-Centrally Symmetric Reflexive Polytopes Arising from Posets

Abstract Twinned chain polytopes form a broad class of non-centrally symmetric reflexive polytopes and exhibit intriguing structures. In the present paper, we show that the number of facets of d -dimensional twinned chain polytopes is at most $$6^{d/2}$$ 6 d / 2 . In case d is ev...

H I Absorbers as Beacons of Hidden Structure at z ~ 3: Multi-Component, Metal-Rich Absorption System near a Protocluster

Abstract H i gas traces the large-scale structure and provides the primary fuel for star formation. High-z protoclusters are ideal laboratories to study how H i gas is accreted and consumed during the formation of the most massive structures in the Universe. However, much remains...

Postsynthetic Zn(II)Species Modification Regulatesthe Surface States of TiO2 Nanoparticles for Resonance-AssistedSERS

Abstract Engineering interfacial electronic states at the nanoscale is a powerful yet underdeveloped strategy for improving the selectivity of semiconductor-based molecular sensing. Here, we report a simple postsynthetic surface-associated Zn(II) species modification approach to...

Substrate-PairedElectron Donor–Acceptor ComplexesEnable Photochemical Alkyl–Alkyl Cross-Coupling

Abstract Selective C(sp3)–C(sp3) cross-coupling of two distinct alkyl radicals is difficult because homocoupling and radical decomposition compete with heterocoupling. We report a catalyst-free, redox-neutral photochemical coupling of alkylpyridinium salts with alkylboron reagent...
