Fintech innovations are enabling access to financial services through mobile devices for many unbanked in the world. Though fintech innovations are touted as game changers in deepening financial ...inclusion, their wide acceptance and use still remain limited. In the extant literature, technological and behavioural antecedents that influence users’ behaviour toward financial technologies are not fully understood. This study argues that understanding antecedents to the actual use of fintech innovations will lead to deepening financial inclusion. Using mobile money—a type of fintech innovation, this study adopts the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) and the Prospect theory. Drawing on survey data collected from 294 respondents, this study applies the partial least square structural equation modelling technique. The findings show that performance and effort expectancy have significant relationship with the intention to use mobile money services. However, contrary to well-established positions, price value, hedonic motivation, social influence and perceived risk do not influence intention and use of mobile money services. The study makes significant theoretical contributions and offers practical and policy implications for deepening financial inclusion.

Global sourcing and increased interdependencies between organisations have created more complex multi-tier supply chains. While these supply chains have been instrumental in keeping the world moving, ...they equally pose sustainability issues. In the extant literature, there is a growing number of studies on sustainable multi-tier supply chains. However, there has been limited effort to take stock of existing research to set an agenda for future studies. To address this gap, this study reviews 64 articles through the lens of the triple bottom line theory. Based on the findings, the study develops a framework for sustainable multi-tier supply chains and provides direction for future research.

The experimental results on the ratios of branching fractions R(D)=B(Bover ¯→Dτ^{-}νover ¯_{τ})/B(Bover ¯→Dℓ^{-}νover ¯_{ℓ}) and R(D^{*})=B(Bover ¯→D^{*}τ^{-}νover ¯_{τ})/B(Bover ¯→D^{*}ℓ^{-}νover ...¯_{ℓ}), where ℓ denotes an electron or a muon, show a long-standing discrepancy with the standard model predictions, and might hint at a violation of lepton flavor universality. We report a new simultaneous measurement of R(D) and R(D^{*}), based on a data sample containing 772×10^{6} BBover ¯ events recorded at the ϒ(4S) resonance with the Belle detector at the KEKB e^{+}e^{-} collider. In this analysis the tag-side B meson is reconstructed in a semileptonic decay mode and the signal-side τ is reconstructed in a purely leptonic decay. The measured values are R(D)=0.307±0.037±0.016 and R(D^{*})=0.283±0.018±0.014, where the first uncertainties are statistical and the second are systematic. These results are in agreement with the standard model predictions within 0.2, 1.1, and 0.8 standard deviations for R(D), R(D^{*}), and their combination, respectively. This work constitutes the most precise measurements of R(D) and R(D^{*}) performed to date as well as the first result for R(D) based on a semileptonic tagging method.
We present a measurement of R_{K^{*}}, the branching fraction ratio B(B→K^{*}μ^{+}μ^{-})/B(B→K^{*}e^{+}e^{-}), for both charged and neutral B mesons. The ratio for the charged case R_{K^{*+}} is the ...first measurement ever performed. In addition, we report absolute branching fractions for the individual modes in bins of the squared dilepton invariant mass q^{2}. The analysis is based on a data sample of 711 fb^{-1}, containing 772×10^{6} BBover ¯ events, recorded at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. The obtained results are consistent with standard model expectations.

We report the first observation of the spontaneous polarization of Λ and Λover ¯ hyperons transverse to the production plane in e^{+}e^{-} annihilation, which is attributed to the effect arising from ...a polarizing fragmentation function. For inclusive Λ/Λover ¯ production, we also report results with subtracted feed-down contributions from Σ^{0} and charm. This measurement uses a dataset of 800.4 fb^{-1} collected by the Belle experiment at or near a center-of-mass energy of 10.58 GeV. We observe a significant polarization that rises with the fractional energy carried by the Λ/Λover ¯ hyperon.
