Perceived Importance of Success Factors of Firms Practicing E-Logistics in Supply Chain: An Exploratory Study on Extranet
One way to enhance the success of supply chain is through the adoption of e-logistics. Much literature discusss the success stories of supply chain, it is however lacked of the determination of its success factors in the e-logistics environment. Extranet is considered as an enabler/system that could enrich the betterment of service quality in e-logistics. This paper identifies four success factors influencing to the success of Extranet; namely the quality of system, information, service and work performance. Furthermore, the analysis on its significant decision variables in each success factor through the concept of SERVQUAL is also presented
UNDERSTANDING CONSUMER TRUST IN SOCIAL COMMERCE WEBSITES
The social commerce represents a new form of electronic commerce mediated by social networking sites. It provides companies with competitive tools for online promotion, and it also assists consumers to make better-informed purchasing decisions based on the sharing of experiences from other consumers. Trust is important in social commerce environment as it serves as a foundation for consumers to evaluate product information from companies as well as from other consumers. However, extant literature still lacks clear understanding of the nature of trust in social commerce. This study sets out to understand trust development in social commerce websites. Specifically, based on trust transference theory, we develop a research model to examine how consumer trust in social commerce impacts their trust in the company and their electronic word of mouth intention. In addition, we also examine how customers’ prior transaction experience with a company could impact their social commerce trust development and serve as a mediator in the trust transfer process. The research model is empirically examined using a survey method consisting of 375 users of a social commerce website. This study contributes to the conceptual and empirical understanding of trust in social commerce. The academic and practical implications of this study are also discussed
Neuroimaging in Leber Hereditary Optic Neuropathy: State-of-the-art and future prospects
Leber Hereditary Optic Neuropathy (LHON) is an inherited mitochondrial retinal disease that causes the degeneration of retinal ganglion cells and leads to drastic loss of visual function. In the last decades, there has been a growing interest in using Magnetic Resonance Imaging (MRI) to better understand mechanisms of LHON beyond the retina. This is partially due to the emergence of gene-therapies for retinal diseases, and the accompanying expanded need for reliably quantifying and monitoring visual processing and treatment efficiency in patient populations. This paper aims to draw a current picture of key findings in this field so far, the challenges of using neuroimaging methods in patients with LHON, and important open questions that MRI can help address about LHON disease mechanisms and prognoses, including how downstream visual brain regions are affected by the disease and treatment and why, and how scope for neural plasticity in these pathways may limit or facilitate recovery
"A Free thenar flap – A case report"
We present a case report of a free thenar flap surgery done for a volar right hand middle finger, distal and middle phalanx degloving injury. A free thenar flap is a fasciocutaneous sensate flap supplied by a constant branch of the superficial radial artery and its variable nerve supply. It has a distinct advantage of low donor site morbidity, better cosmesis and texture of the flap. No immobilization is required postop. The donor site can be closed primiarily

Ronald Ma and colleagues describe the differential diagnosis, investigation, and management of a 21-year-old pregnant woman presenting with hypertension and proteinuria at 20 weeks of gestation
Intermolecular CT excitons enable nanosecond excited-state lifetimes in NIR-absorbing non-fullerene acceptors for efficient organic solar cells
State-of-the-art Y6-type molecular acceptors exhibit nanosecond excited-state
lifetimes despite their low optical gaps (~1.4 eV), thus allowing organic solar
cells (OSCs) to achieve highly efficient charge generation with extended
near-infrared (NIR) absorption range (up to ~1000 nm). However, the precise
molecular-level mechanism that enables low-energy excited states in Y6-type
acceptors to achieve nanosecond lifetimes has remained elusive. Here, we
demonstrate that the distinct packing of Y6 molecules in film leads to a strong
intermolecular charge-transfer (iCT) character of the lowest excited state in
Y6 aggregates, which is absent in other low-gap acceptors such as ITIC. Due to
strong electronic couplings between the adjacent Y6 molecules, the iCT-exciton
energies are greatly reduced by up to ~0.25 eV with respect to excitons formed
in separated molecules. Importantly, despite their low energies, the iCT
excitons have reduced non-adiabatic electron-vibration couplings with the
electronic ground state, thus suppressing non-radiative recombination and
allowing Y6 to overcome the well-known energy gap law. Our results reveal the
fundamental relationship between molecular packing and nanosecond excited-state
lifetimes in NIR-absorbing Y6-type acceptors underlying the outstanding
performance of Y6-based OSCs
