Impact of Corporate Social Responsibility on Consumers\u27 Purchase Behavior in the E-commerce Environment

The development of the Internet has promoted the prosperity of e-commerce, and has a great impact on today\u27s consumers\u27 consumption concepts. For e-commerce platform, this is not only an opportunity, but also a challenge. If we gain advantages in the fierce competition environment, it will become the leader in the e-commerce environment. Corporate social responsibility has a significant impact on the operation and development of enterprises. With the increasing attention of society to corporate social responsibility, social responsibility is gradually becoming an important factor in determining the value of enterprises, which is also the case for e-commerce platforms. In order to provide a new way for the development of e-commerce platform, this paper analyzes the impact of corporate social responsibility on consumer purchasing behavior, and discusses the significance of corporate social responsibility on e-commerce platform

Research on Consumers\u27 Buying Behavior in the Context of Helping Farmers Live”: Based on the Dual Role of Economic Rationality and Normative Rationality

As the digital economy has become an important driving force for a new round of global industrial change, live ecommerce has become a new outlet, and the agriculture assisted live broadcasting has emerged. This paper combs the existing literature and combines the characteristics of agriculture assisted live broadcasting to get a theoretical research model of consumers\u27 purchasing behavior in the context of assisted farmer direct broadcast . Using questionnaire survey method to collect data for empirical analysis, the research found that consumers’ perceived risk negatively affects purchase intention; efficacy positively affects purchase intention; consumer purchase intention positively affects purchase behavior; consumer perceived value and social norms have no significant effect on purchase intention. Finally, this article makes suggestions for businesses and relevant departments of the live broadcast industry

Content-Based Hyperspectral Image Compression Using a Multi-Depth Weighted Map With Dynamic Receptive Field Convolution

In content-based image compression, the importance map guides the bit allocation based on its ability to represent the importance of image contents. In this paper, we improve the representational power of importance map using Squeeze-and-Excitation (SE) block, and propose multi-depth structure to reconstruct non-important channel information at low bit rates. Furthermore, Dynamic Receptive Field convolution (DRFc) is introduced to improve the ability of normal convolution to extract edge information, so as to increase the weight of edge content in the importance map and improve the reconstruction quality of edge regions. Results indicate that our proposed method can extract an importance map with clear edges and fewer artifacts so as to provide obvious advantages for bit rate allocation in content-based image compression. Compared with typical compression methods, our proposed method can greatly improve the performance of Peak Signal-to-Noise Ratio (PSNR), structural similarity (SSIM) and spectral angle (SAM) on three public datasets, and can produce a much better visual result with sharp edges and fewer artifacts. As a result, our proposed method reduces the SAM by 42.8% compared to the recently SOTA method to achieve the same low bpp (0.25) on the KAIST dataset

Testing for homogeneity of gametic disequilibrium across strata

Copyright © 2007 Yin et al. Background: Assessing the non-random associations of alleles at different loci, or gametic disequilibrium, can provide clues about aspects of population histories and mating behavior and can be useful in locating disease genes. For gametic data which are available from several strata with different allele probabilities, it is necessary to verify that the strata are homogeneous in terms of gametic disequilibrium. Results: Using the likelihood score theory generalized to nuisance parameters we derive a score test for homogeneity of gametic disequilibrium across several independent populations. Simulation results demonstrate that the empirical type I error rates of our score homogeneity test perform satisfactorily in the sense that they are close to the pre-chosen 0.05 nominal level. The associated power and sample size formulae are derived. We illustrate our test with a data set from a study of the cystic fibrosis transmembrane conductance regulator gene. Conclusion: We propose a large-sample homogeneity test on gametic disequilibrium across several independent populations based on the likelihood score theory generalized to nuisance parameters. Our simulation results show that our test is more reliable than the traditional test based on the Fisher's test of homogeneity among correlation coefficients. © 2007 Yin et al; licensee BioMed Central Ltd.This research was supported by the National Natural Science Foundation of China (Grant Numbers 10431010 and 10701022), National 973 Key Project of China (2007CB311002), NCET-04-0310, EYTP, the Jilin Distinguished Young Scholars Program (Grant Number 20030113) and the Program Innovative Research Team (PCSIRT) in University (#IRT0519).

Bus Travel Time Deviation Analysis Using Automatic Vehicle Location Data and Structural Equation Modeling

To investigate the influences of causes of unreliability and bus schedule recovery phenomenon on microscopic segment-level travel time variance, this study adopts Structural Equation Modeling (SEM) to specify, estimate, and measure the theoretical proposed models. The SEM model establishes and verifies hypotheses for interrelationships among travel time deviations, departure delays, segment lengths, dwell times, and number of traffic signals and access connections. The finally accepted model demonstrates excellent fitness. Most of the hypotheses are supported by the sample dataset from bus Automatic Vehicle Location system. The SEM model confirms the bus schedule recovery phenomenon. The departure delays at bus terminals and upstream travel time deviations indeed have negative impacts on travel time fluctuation of buses en route. Meanwhile, the segment length directly and negatively impacts travel time variability and inversely positively contributes to the schedule recovery process; this exogenous variable also indirectly and positively influences travel times through the existence of signalized intersections and access connections. This study offers a rational approach to analyzing travel time deviation feature. The SEM model structure and estimation results facilitate the understanding of bus service performance characteristics and provide several implications for bus service planning, management, and operation
