Intentions to participate in political crowdfunding- from the perspective of civic voluntarism model and theory of planned behavior

The study has integrated the civic voluntarism and planned behavior model to check the intentions of people towards political crowdfunding. Participation in politics is the civic duty of a citizen in a democratic country and exercising this right leads to government formation. Participation in the political process is behavior influenced by the intention to do so. The study examines the influence of the civic voluntarism model (CVM) and the theory of planned behavior (TPB) factors on the intention to participate in political crowdfunding. The study was done in India, the largest democracy in the world, taking a sample size of 374 respondents. Partial least square structural equation modeling (PLS-SEM) was used to analyze the data through SmartPLS-3.2. The results of this study revealed that resources - financial, time, and technological - are essential for participating in political crowdfunding. Political engagement, political interest, and political awareness are significantly associated with the intention to participate in crowdfunding. Online community engagement also shows a positive relationship with the intention. Among the three factors of TPB, attitude and subjective norms are significantly influencing the intention towards participation. The results of this study will help the political parties and candidates to identify factors that will help them to get maximum funding and support from the crowd through political crowdfunding. The theoretical implication is that political crowdfunding can come up as a distinct segment of crowdfunding to be studied.     

Perceived derived attributes of online customer reviews

The influence of online customer reviews (OCRs) on customers' purchase intention has recently gained considerable attention, in both academic and business communities. Technology allows customers to freely and easily post their comments and opinions online about any product or service; this type of customer review can have a significant effect on customers' purchase decisions. Previous studies, however, have mainly focused on the influence of the virtual attributes of OCRs such as volume and valence on consumers' intentions, while limited attention has been paid to understanding the effects of the derived attributes. This study, thus, aims to understand the impact of the perceived derived attributes of OCRs on customer trust and intention. This study develops a – Perceived Derived Attributes (PDA) - model, based on the inclusion of perceived control from the Theory of Planned Behaviour (TPB) with the Technology Acceptance Model (TAM), in order to investigate the effects of OCRs on customers’ purchasing intention. A total of 489 responses to a survey were collected from users of amazon.com. The findings from this study suggest that customer trust in an e-vendor and their intention to shop online are significantly affected by perceived usefulness, perceived ease of use and perceived enjoyment of OCRs. Furthermore, the sense of control derived from OCRs significantly affects customer intention and significantly affects customer trust in e-vendors, particularly for customers who frequently check OCRs before making a purchase. Clearly, those attributes of OCRs are linked to the development of the shopping environment, which consequently can affect sales.     

Novel core–shell structure of perovskite anode and characterization

The core–shell anode particulates are prepared with perovskite core of (Sr_0.7La_0.3)(Ti_1−xNb_x)O₃ and the shell of multiple elements doped solid electrolyte (La_0.75Sr_0.2Ba_0.05)_0.175Ce_0.825O_1.891 (LSBC) by a citric acid-based combustion (SV) coating process. The ionic shell LSBC precedes the peak reduction–oxidation reaction temperature of the anode to 500 °C. The selected coverage ratio of 1.5 or 3.0 mol% LSBC shell on the core is used to ensure appropriate electrocatalytic activity and electronic conductivity. The core–shell anode increases the interface charge transfer (ReZ(i)) and chemical catalysis (ReZ(c)) that is revealed on the reduction of AC impedance. The lower slope of the voltage drop for the half-cell, which is composed of the core–shell anode, indicates the increasing effective triple phase boundary (TPB) sites and reduces the interface thermal expansion and lattice matching, as well as extends the ionic conduction path from LSBC electrolyte to the core–shell anode. The power density increases three times by using the core–shell structural anode than without using the core–shell anode in the half-cell.     

Improved solvation routes for the Bunsen reaction in the sulphur iodine thermochemical cycle: Part III–Bunsen reaction in molecular solvents

Operating the Bunsen reaction in a solvent has the potential to increase SI cycle efficiency and decrease operating costs. Analysing the solvent–acid mixtures produced is complicated as additional acid is formed when SO₂ comes into contact with water. Tri-n-butyl phosphate (TBP) is suitable for HI extraction; however, it is susceptible to acid catalysed dealkylation, resulting in solvent decomposition and the production of butyl iodide. Cyanex^® 923 is found to be superior to TBP in the Bunsen reaction due to its high affinity for HI. Strong orange complexes between HI, SO₂ and the phosphoryl group in Cyanex^® 923 are formed, giving good product separation, however severely hampering HI recovery. Washing the organic phase with water resulted primarily in the removal of H₂SO₄. HI could then be recovered either thermally or with a second wash step.     

Recovery of 137Cs from Laboratory Waste using Solvent Extraction with Sodium Tetraphenylboron (TPB)

The paper describes a method for the recovery of ¹³⁷Cs from an aqueous radioactive laboratory waste solution containing ¹³⁷Cs (2 µg/mL) in the presence of high concentration of Na⁺ using solvent extraction technique. The method comprises of adjustment of pH to the acidic range (pH = 2), contacting the aqueous radioactive solution with sodium tetraphenylboron (TPB) in nitrobenzene, whereby ¹³⁷Cs binds with tetraphenylboron anions and gets separated. Results of this investigation indicate that ¹³⁷Cs could be efficiently and selectively extracted from an aqueous solution media containing high concentration of Na⁺ under mildly acidic pH into an organic phase and back extracted with small volume of 3 M HNO₃, thus enabling concentration. The proposed method was successfully applied in real samples.     

Digital piracy intention: a comparison of theoretical models

Digital piracy intention research has yielded different sets of piracy intention determinants based on various theoretical models. In this study, we reviewed the digital piracy literature and empirically compared two theoretical models, which are the models most often used: the theory of planned behaviour (TPB) and the Hunt–Vitell ethical decision model. Data were obtained from university students in South Korea, and structural equation modelling (SEM) was employed to examine and compare the two competing theoretical models in terms of explanatory power, overall model fit and paths' significance. The findings of this study revealed that the TPB is a more appropriate model for predicting digital piracy than the Hunt–Vitell ethical decision model.     

Effect of length of gas/liquid/solid three-phase boundary zone on cathodic and corrosion behavior of metals

Liquid dispersion, depending on the length of gas/liquid/solid three-phase boundary (TPB) zone of dispersed liquid on a metal surface, is an important property of liquid state influencing corrosion behavior of metals in gas/liquid/solid multiphase corrosion systems. The effect of TPB length on the cathode and corrosion process was studied using steady state polarization technique, electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) technique. It was found that both the cathodic limiting current density and corrosion current density linearly increased with increasing the TPB length, indicating that the cathodic and corrosion process in gas/liquid/solid multiphase corrosion systems not only depended on the thickness of liquid layer but also strongly depended on the dispersed liquid state on a metal surface. In addition, a model is developed to establish the relationship between the cathodic limiting current density and the TPB length. The simulation result is in good agreement with the experimental findings. The model is also useful for evaluating the effect of liquid dispersion on atmospheric corrosion rates.

Adoption of e-book among college students: The perspective of an integrated TAM

This study explored factors that affect consumer acceptance of e-book use by applying a model that incorporates the Technology Acceptance Model (TAM) as the theoretical basis of the hypotheses. The model differentiated external factors—compatibility, relative advantage, self-efficacy, and subjective norms—from internal factors—perceived ease of use, perceived usefulness, satisfaction with e-book usage, and intention to continue using e-books. The study (n = 1030) found statistically significant support for the hypothesized model, indicating that the tested relationships between the revised TAM and user intention to continue using e-books were positive and statistically significant. The study’s findings provide potentially significant implications that can be used to develop guidelines and a framework for assessing e-book users’ behavior.
