Factors affecting the adoption of B2B e-commerce technologies

Abstract: The objective of this study is to analyze the factors affecting the adoption of Internet-enabled business-to-business electronic commerce (B2B EC) and test their applicability in different contexts. We used 275 responses from an online survey of North American firms and tested our hypotheses with Multiple Regression and Analysis of Variance (ANOVA). We found that scalability is the biggest contributor to B2B EC usage. We also compared each adoption factor across adopters and nonadopters of B2B EC. Six of the nine adoption factors tested distinguished adopters of B2B EC from nonadopters. Then we analyzed the effects of these factors on adoption using several contextual variables, including firm size, firm type, management level of respondents, and country of origin of firms. The results showed that all of the contextual variables, except country of origin, influenced some of the adoption factors. Managers can use the findings of this study to understand which factors will most likely facilitate the implementation of B2B EC and be prepared to manage the effects of these factors on their initiatives more effectively. Many of the studies in this area have not tested the effects of contextual variables on B2B EC adoption. Thus, we contribute to the limited literature on this issue. The study shows that the technology---organization---environment (TOE) framework provides a strong foundation for the study of B2B EC. It also provides evidence that this framework is strengthened further when contextual variables are integrated into the theoretical model.

Modeling CO2 emissions in Malaysia: an application of Maki cointegration and wavelet coherence tests

Abstract: One of humanity's most significant problems in the twenty-first century revolves around how to balance the mitigation of environmental pollution while achieving sustainable economic development. Despite increased awareness and dedication to climate change, the planet is still seeing a drastic decrease in the volume of pollutant emissions. This study explores the long-run and causal impact of economic growth, financial development, urbanization, and gross capital formation on Malaysia's CO2 emissions based on the STIRPAT framework. The current paper employs recently developed econometric techniques such as Maki co-integration, auto-regressive distribution lag (ARDL), fully modified OLS (FMOLS), dynamic ordinary least square (DOLS), and wavelet coherence and gradual shift causality tests to investigate these interconnections. The advantage of the gradual shift causality test is that it can capture the causality in the presence of a structural break(s). The findings from the Maki co-integration and ARDL bounds tests reveal evidence of cointegration among the variables. The ARDL test reveals that economic growth, gross capital formation, and urbanization exert a positive impact on CO2 emissions. Furthermore, the wavelet coherence test reveals that there is a significant dependency between CO2 emissions and economic growth, gross capital formation, and urbanization. The Toda Yamamoto and Gradual shift causality tests reveal that there is a (a) unidirectional causality from urbanization to CO2 emissions, (b) unidirectional causality from economic growth to CO2 emissions, and (c) unidirectional causality from gross capital formation to CO2 emissions.

Acetaminophen removal from aqueous solutions through peroxymonosulfate activation by CoFe2O4/mpg-C3N4 nanocomposite: Insight into the performance and degradation kinetics

Abstract: In this study, a mesoporous composite (CoFe2O4/mpg-C 3 N4, CF/MCN) was synthesized by a simple method. The characteristics of the prepared sample were determined by different methods including XRD, FESEM, EDX-map, FTIR, BET, and pH zpc . Characterization results showed that CF/MCN was well synthesized with small size and good dispersion of CF nanoparticles. Catalytic activity of CF/MCN was evaluated by peroxymonosulfate (PMS) activation to degrade acetaminophen (APAP) through the generation of free radicals. The effect of key factors of CF/MCN/PMS process on APAP degradation was assessed. CF/MCN/PMS degraded more than 92% of APAP under the conditions of pH = 7.0, PMS = 1.5 mM, 40 mg/L CF/MCN and 25 min reaction time. Pseudo-first order kinetic model was fitted for APAP removal and the rate constant obtained was 0.1023 min−1. Sulfate radical ( SO 4 • − ) was the main contributor in APAP degradation. Carbonate and chloride ions had a strong inhibitory effect on APAP degradation whereas other anions (nitrate and sulfate ions) affected slightly APAP degradation. CF/MCN was a reusable catalyst for four times without any significant reduction in catalytic activity. Leaching experiments demonstrated a negligible concentration of Co and Fe indicating that homogeneous activation did not contribute in the generation of free radicals. The CF/MCN exhibited high catalytic activity for mineralization of APAP compared to other conventional metal oxides. This method can be used as an alternative advanced oxidation process for efficient degradation of emerging pollutants in water.
