Impact of congestion pricing schemes on emissions and temporal shift of freight transport

Abstract: This paper examines the freight transport temporal shift and the vehicular pollutants emissions in an urban transport network with congestion pricing schemes, specifically when only freight transportation is tolled in the peak period. The equivalent minimization models of no-toll, first-best, and second-best congestion pricing scenarios are presented with an excess-demand approach based on user equilibrium analysis, in which the different pricing schemes include multiple time periods and mixed traffic. We established results for the equivalent conditions and the uniqueness conditions of the models. The findings and policy insights are discussed using simulation and sensitivity analysis of the key parameters.

Understanding corporate social responsibility with cross‐cultural differences: A deeper look at religiosity

Abstract: Contemporary economic and business settings have brought people of different cultures at the common workplace. This directs business researchers to study cross‐cultural similarities, differences, and management of employees, customers, and other stakeholders. This theoretical review is aimed to explore the variation in religion, practices, and their effects on corporate social responsibility (CSR) disclosure and practices. With an unfathomable analysis of relevant literature, this paper has highlighted the knowledge gap in the relationship of cross‐cultural differences and CSR. Subsequently, it presents three propositions in connection of religious variation and CSR disclosure and practice. Underpinning the practical difference in lifestyle of people having the same religious beliefs in different geographical areas, this article reflects that an extension in stakeholder theory may be suggested with the support of postempirical evidence.

Electrochemical sandwich immunoassay for Escherichia coli O157:H7 based on the use of magnetic nanoparticles and graphene functionalized with electrocatalytically active Au@Pt core/shell nanoparticles

Abstract: A highly sensitive electrochemical sandwich immunoassay is described for determination of Escherichia coli O157:H7 (E. coli O157:H7). Silica coated magnetite nanoparticles (Fe3O4) were modified with primary antibody to capture E. coli O157:H7. Gold-platinum core/shell nanoparticles (Au@Pt NPs) with different Pt shell thicknesses were prepared via changing the molar ratio of H2PtCl6 to HAuCl4 in the precursor solution. The optimized Au@Pt NPs exhibit enhanced activity in the electrocatalytic reduction of hydrogen peroxide (H2O2). The Au@Pt NPs were modified with graphene that was functionalized with Neutral Red, and then used as an electrochemical label for secondary antibodies and horseradish peroxidase (HRP). The sandwich immunocomplexes were magnetically absorbed on a 4-channel screen printed carbon electrode. Due to the catalysis of the Au@Pt NPs and HRP, the signal is strongly amplified in the presence of H2O2 when using thionine as the electron mediator. Under optimal conditions, the immunoassay has a linear response in the 4.0 × 102 to 4.0 × 108 CFU·mL−1 concentration range, with a limit of detection of 91 CFU·mL−1 (at an S/N ratio of 3).
