The massive web-based information resources have led to an increasing demand for effective automatic retrieval of target information for web applications. This paper introduces a web-based data extraction tool that deploys various algorithms to locate, extract and filter tabular data from HTML pages and to transform them into new web-based representations. The tool has been applied in an aquaculture web application platform for extracting and generating aquatic product market information. Results prove that this tool is very effective in extracting the required data from web pages. 展开更多

The current study represents an attempt at exploring product attribute, service attribute evaluation, and buyer regret influence overall satisfaction in the buyer decision context. The data used in the project were collected as part of a large study of buyer regret. The sampling frame consisted of automobile purchases in Taiwan We have collected yield 600 questionnaires, by screening out 44 questionnaires, including those missing value or incomplete answer, and finally a usable sample of 556 questionnaires were utilized in this study. The results reinforce the finding form early research that the concept of buyer regret plays an important role for automobile purchases in the buyer decision. Results show that higher evaluations of service and product attributes lead to less buyer regret, and lower buyer regret will likely to increase overall satisfaction. Specifically, the finding indicates that buyer regret mediates the effects of the attributes on overall satisfactions. Implications for marketing theory and practitioners are discussed, and possible directions for future research are sketched. 展开更多

This article is a part of a descriptive survey which aims to characterize, classify, and compare the household production in the Municipality of Itapuranga, State of Goias, Brazil, considering the access to the National Program for Strengthening Family Agriculture (PRONAF) and its respective differentiation between beneficiary and non-beneficiary groups by the program. It applied the technique of group comparison analysis and frequency inquiry, taking into consideration several variables. Information about the origin, distribution and total income, food safety, land property, production diversification, expenditures and participation in social organizations were collected. The sample consisted of 70 producers, the calculation sample was defined by determined value at the confidence level of 90% whereas the sampling error of 7%. The results allowed describing, classifying, characterizing, and comparing the socio-economic and productive profile of farmers from that area and their access to PRONAF. 展开更多

The field of stretchable electronics mainly includes electronic products conformal with tissues,being integrated into skin or clothing.Since these products need to work during deformation,their requirements for materials focus on stretchability and conductivity.Liquid metals are excellent materials with these properties.However,liquid metals have extremely high surface tension at room temperature,which will spontaneously form a spherical shape and are difficult to form the shape required by stretchable devices,which is the biggest obstacle to their development in this emerging field.Therefore,the emphasis is placed on the principle of overcoming the high surface tension in this review,and various methods of using liquid metals to fabricate stretchable electronic devices based on these principles have been linked.Liquid metals show promise in the convenience of sensing,energy harvesting,etc.The existing challenges and opportunities are also discussed here. 展开更多
