ABSTRACT
Although the importance and benefits of logistics integration in omni-channel (OC) retailing have been discussed in the literature, the impacts of logistics integration from the dimension of internal and external logistics remain unknown. To fill this gap, this study aims to investigate the relationships among internal and external logistics integration capabilities, supply-chain integration (SCI), and financial performance (FP) in OC retailing based on the dynamic capability view. An empirical study is conducted based on a survey of 230 OC retailers in China's market. Factor analysis and regression analysis are conducted to examine the hypotheses of the proposed conceptual model. The quantitative analyses show that the internal logistics integration capability is significantly related to the external logistics integration capability, and they both have positive effects on SCI, while the external logistics integration capability generates a higher impact (i.e., almost 1.5 times that of the internal logistics integration capability). The numerical results also demonstrate that the logistics integration capabilities and SCI have similar positive effects on FP (i.e., all the relevant regression coefficients show values around 0.25), and SCI plays a partial intermediary role in the relationships between logistics integration capabilities and FP. Furthermore, the quantitative evidence addresses the fact that the FP is not influenced by OC retailers' characteristics, indicating a fair business environment in the OC retail industry.
ABSTRACT
This paper examines the efficacy of telemedicine (TM) technology compared to traditional face-to-face (F2F) visits as an alternative healthcare delivery service for managing diabetes in populations residing in urban medically underserved areas (UMUPAs). Retrospective electronic patient health records (ePHR) with type 2 diabetes mellitus (T2DM) were examined from 1 January 2019 to 30 June 2021. Multiple linear regression models indicated that T2DM patients with uncontrolled diabetes utilizing TM were similar to traditional visits in lowering hemoglobin (HbA1c) levels. The healthcare service type significantly predicted HbA1c % values, as the regression coefficient for TM (vs. F2F) showed a significant negative association (B = −0.339, p < 0.001), suggesting that patients using TM were likely to have 0.34 lower HbA1c % values on average when compared with F2F visits. The regression coefficient for female (vs. male) gender showed a positive association (B = 0.190, p < 0.034), with HbA1c % levels showing that female patients had 0.19 higher HbA1c levels than males. Age (B = −0.026, p < 0.001) was a significant predictor of HbA1c % levels, with 0.026 lower HbA1c % levels for each year's increase in age. Black adults (B = 0.888, p < 0.001), on average, were more likely to have 0.888 higher HbA1c % levels when compared with White adults.
ABSTRACT
The extension of quantile regression to count data raises several issues. We compare the traditional approach, based on transforming the count variable using jittering, with a recently proposed approach in which the coefficients of quantile regression are modelled by parametric functions. We exploit both methods to analyse university students' data to evaluate the effect of emergency remote teaching due to COVID-19 on the number of credits earned by the students. The coefficients modelling approach performs a smoothing that is especially convenient in the tails of the distribution, preventing abrupt changes in the point estimates and increasing precision. Nonetheless, model selection is challenging because of the wide range of options and the limited availability of diagnostic tools. Thus the jittering approach remains fundamental to guide the choice of the parametric functions.
ABSTRACT
This study investigates the psychological restorative benefits of indoor vertical greenery and its relationship with visual satisfaction. Taking the Solar Decathlon China 2018 champion project “LONG-PLAN” as the experimental field, we conducted a questionnaire survey to evaluate the effect of indoor vertical greenery on creating a restorative environment. Then we further studied the relationship between the restorative environmental factors and visual satisfaction of indoor vertical greenery. The results show that: (1) Indoor vertical greenery has a positive impact on the subjective restoration of respondents (the average value of PRS = 4.150). (2) The three factors of “being away,” “fascination and compatibility,” and the “extent” of environmental restoration have a significant positive correlation with the visual satisfaction of indoor vertical greenery (the correlation coefficient values are 0.403, 0.627, and 0.425, respectively, p < 0.01). (3) In the stepwise regression analysis of the three factors and the visual satisfaction of indoor vertical greenery, only “fascination and compatibility” show a significant positive correlation (the regression coefficient = 0.753, p < 0.01). (4) The visual satisfaction of indoor vertical greenery has a significantly positive impact on environmental recovery (the regression coefficient = 0.459, p < 0.01). The study shows that indoor vertical greenery improves visual satisfaction and contributes to a restorative environment. In addition, the study provides further evidence of the mutual facilitation between restorative benefits and visual satisfaction.
