人工锄草器的设计研究

本文针对农田杂草去除问题,结合传统除草机的运动方式,设计出了一种节省人力、对环境无污染、锄草效率高、伤苗率低的人工锄草器。该锄草器以剪齿为主要工作部件,利用上下剪齿在土壤中的相对运动,剪断草根,从而达到除草的目的。在设计中选用了双轮滚动式人力驱动,利用滚轮与地面的滚动摩擦减小除草过程中的阻力,从而节省人力,提高工作效率。

Effects of Various Types of Cause-Related Marketing (CRM) Ad Appeals on Consumers' Visual Attention,Perceptions, and Purchase Intentions

ABSTRACT

The study examined whether various types of cause-related marketing (CRM) appeals (informational, emotional, or a combination of the two) influenced visual attention, as captured by eye fixation, and perceptions of the company and the ad, thus, leading to purchase intentions. The results suggest that a combined appeal generates more favorable responses to the ad. An eye-tracking experiment showed that an informational ad led to longer visual attention, and that visual attention was affected by the level of consumers' cause involvement. Visual attention had a negative impact on company credibility. Company credibility mediated the relationship between visual attention and CRM ad attitudes.     

Not all organic food is created equal: the role of product type,perceived authenticity,and construal level

Abstract

Consumption of processed organic food is on the rise while fresh organic food still dominates organic food market. Drawing from the literature on authenticity and construal level theory, this study aims to investigate the role of perceived authenticity and message construal level in consumers’ evaluations of two types of organic food (fresh vs. processed). Two experiments were conducted among college students (N = 129, Study 1) and adults 18–70 (N = 249, Study 2). Our findings suggest that consumers’ evaluations of organic food are fully mediated by perceived authenticity of each organic food type. Specifically, compared to processed organic food, consumers perceive fresh organic food more authentic, which leads to more favorable attitudes and higher purchase intention. This research further demonstrates that the indirect effect of organic food type via perceived authenticity is moderated by construal level of marketing messages. That is, when messages are construed at a low level, consumers tend to have more positive attitudes and higher purchase intention toward fresh than processed organic food. By contrast, product type makes no difference when messages are construed at a high level. These findings have clear implications on message development strategy when promoting processed organic food, in particular. Future research directions are discussed.     

Preferred Leisure Type,Value Orientations,and Psychological Well-Being Among East Asian Youth

ABSTRACT

This study investigated preferred leisure type and its associations with value orientations and psychological well-being (PWB) among adolescents in South Korea, China, and Japan (N = 6,157). Chi-square analyses were performed to examine differences in preferred leisure type (i.e., active vs. passive) across countries. Overall, adolescents preferred passive to active leisure. A series of logistic regressions showed that students who value religion (Japanese and Korean), community (Chinese), and same-sex friends (Chinese) were more likely to prefer active leisure. Furthermore, active leisure pursuit was associated with high PWB among adolescents in all three countries. Though some of the findings support previous studies suggesting cultural differences in leisure, values, and PWB, similar patterns were observed in the associations between variables among Korean, Chinese, and Japanese adolescents.
