What drives brand love and purchase intentions toward the local food distribution system? A study of social media-based REKO (fair consumption) groups

Local food is gaining increasing popularity among consumers due to its association with sustainable consumption. However, for a product to be commercially successful, such growing popularity should translate into high purchase intentions and positive associations with the product post-consumption. Although this success has not yet been reflected for local food consumption, research in this area has remained limited. The present study addresses this gap by examining the antecedents of brand love for both the local food distribution system and the local food it distributes. The study thus employs the stimuli-organism-response (SOR) theory, which indicates that certain environmental stimuli influence the consumers' internal state or organism and shapes their behavior, in turn. Specifically, this study uses altruism as the stimulus, supporting local producers, transparency, satisfaction with labeling, and desire for labeling as the consumers’ internal state (organism), and purchase intentions and brand love as the response. Cross-sectional data were collected from 2045 local food consumers associated with Facebook-based REKO (fair consumption) groups in Finland. Findings indicate that altruism is associated with internal state, i.e., desire for labeling, supporting local producers, and satisfaction with labeling. These variables, in turn, are associated with brand love for the local food distribution system. Furthermore, purchase intentions positively mediate the association of the four internal states with brand love.     

What do customers expect of travel agent–customer interactions? Measuring and improving customer experience in interactions with travel agents

ABSTRACT

The purpose of this study is to explore what customers expect of travel agent–customer interactions by developing a scale of customer service experience; further, a framework to demonstrate how to improve customer service experience derived from interactions with travel agents is proposed. The results indicate that the indirect effect of travel agent interpersonal competencies on word-of-mouth is not through cognitive customer service experience but rather through affective customer service experience. Also, the indirect effect of travel agent professional competencies on word-of-mouth is not through affective customer service experience but rather through cognitive customer service experience.     

Impact of apps aesthetics on revisit intentions of food delivery apps: The mediating role of pleasure and arousal

Online food delivery (OFD) apps are changing the way we consume food. Despite increasing the popularity of OFD apps, limited studies have explored the reason behind popularity which contributes to the revisit intentions. This study investigates the drivers of revisit intentions by adopting stimulus-organism-response (SOR) theory and pleasure arousal dominance (PAD) theory as a theoretical lens. A model is conceptualized by including aesthetic formality and aesthetic appeal of OFD apps as stimuli, pleasure, and arousal as the internal state of the organism, and revisit intentions and word of mouth (WOM) as a response. Data is collected from OFD app users through a survey questionnaire. Findings indicate that aesthetic appeal is associated with pleasure and arousal. Aesthetic formality is associated with pleasure, word of mouth, and revisit intentions. Further, pleasure influences arousal, word of mouth, and revisit intention. The findings also confirmed the mediating role of pleasure and arousal. The study contributes to the practice and theory in the context of online food delivery apps.     

基于复杂性研究视野下的生物学

复杂性是当今科学的前沿,其深刻的思想已经渗透到自然科学、经济、社会、管理等各个领域之中,然而复杂性又是生物学的固有属性。本文对复杂性研究进行了简要的综述,并在三种生物组织水平上——细胞系统、中枢神经系统以及自然生态系统,举例说明了复杂性研究视野下的生物系统。     

我国转基因植物风险控制与安全管理研究

自20世纪70年代初提出生物安全问题以来，转基因生物的风险评估和风险控制工作已受到各国政府和学者的高度重视。20世纪90年代以来，我国转基因植物研究进展迅速，加强转基因植物风险评估与风险控制迫在眉睫。通过研究我国现今转基因植物风险评估与风险控制工作存在的不足。提出了我国转基因植物风险控制的对策。     

我国转基因作物的发展现状及安全管理

转基因作物是当今世界各国现代生物技术产业研究的热点，中国的转基因生物技术发展迅速，由于科学界对转基因作物对人类及生态环境利与弊的争论，政府应制定相应的政策、措施对其进行安全管理。本文论述了转基因作物在国际国内的发展现状，分析了转基因作物对人类及生态环境的利与弊以及关于我国转基因作物安全管理的几点思考。     

论科学旅游发展观的推进机制

科学旅游发展观实施的关键,是这一全新的发展观念不能仅停留在政府和学术研究的层面,而应将其传播到需要实施这一理念的最前线去。从科学发展观和全面小康社会实施的角度,“以人为本”,以“教育”为切入点,“游”“教”互动、“寓教于游”———强化旅游所蕴涵的社会文化教育功能,在旅游经营和消费的各个环节以及各相关利益群体中,坚持不懈地将可持续旅游的理念传播拓展到普及应用的层面上去,培育和完善可持续旅游的教育体系,无疑是科学旅游发展观的有效推进机制。     

转基因植物修复毒性炸药污染

有机污染物的植物修复,如炸药的毒性污染,可能导致毒性代谢产物的积累,这些毒性代谢产物可能进一步进入食物链。在过去的十年中,人们从遗传上改良植物来克服其解毒能力的内在不足。有些细菌基因能编码分解炸药的酶,像硝基还原酶和细胞色素P450,这些细菌基因已被引入高等植物,显著地增强了植物耐受性、吸收和解毒的能力。转基因植物展现出微生物的生物降解能力,为高效环保的净化土壤技术带来了希望。     

Exploring the roles of self-concept and future memory at consumer events: the application of an extended Mehrabian–Russell model

This study aimed to extend Mehrabian and Russell’s stimulus–organism–response (S-O-R) framework to consumer events. Physical environment and staff interaction were evaluated as stimuli which impact event attendees’ self-concept and memory (organism), and lead to behavioral intention (response). Data were collected from the surveys completed by 449 attendees of Armada event. The findings confirmed the impact of physical environment on self-concept and memory, as well as the mediation effect of memory between self-concept and behavioral intention. The study is a pioneer in the application of an extended S-O-R framework with the inclusion of memory.     

转 Bt 杨树对杨扇舟蛾的田间抗性及生物安全性

通过室外人工接虫,研究了表达Cry1A 杀虫蛋白的中嘉8号杨树转 Bt 植株对杨扇舟蛾的田间抗性和对非靶标生物的影响。连续3年的试验结果表明,人工接虫1周后,转 Bt 植株有虫株率为4％～12％,平均为8％;对照组未转化植株有虫株率都在90％以上,平均为93．3％。接虫2个月后,转Bt 植株虫口密度为2．1～3．1头/株,平均为2．5头/株;对照组未转化植株虫口密度为9．7～12．3头/株,平均为11．2头/株,并且转Bt植株和对照组未转化植株林间生物丰度差异都不显著。初步认定,中嘉8号杨树转 Bt 植株对靶标害虫-杨扇舟蛾幼虫具有明显的抗性,而对非靶标生物无明显的毒害作用,具有进一步大田释放的价值。
