User Acceptance of E-Collaboration Technology: An Extension of the Technology Acceptance Model

This study investigates the applicability of Davis' Technology Acceptance Model (TAM) in the user acceptance of electronic collaboration technology. A courseware management tool is used to test the various findings of TAM. Perceived usefulness of the technology emerges as a positive impact on perceived usefulness, and usefulness, in turn, has a negative relationship with system usage. Additionally, certain aspects of system usage influenced student performance in the course. Prior use of the system also affected system use.     

Consumer Acceptance of the New Red-Fleshed Apple Variety

The aim of this study was to investigate consumer preference for the novel red-fleshed apple genotypes. The information presented provides us with insight into consumer propensity to accept a new variety with radical visible innovative attributes and societal demand for a more sustainable production. The survey was carried out on the population of a province in central Italy, where there is consumer demand for organic and high-quality foods. The consumers’ opinions contrasted greatly and can be divided into two groups. Over one quarter of the respondents declared that they did not like the innovative fruit. The cluster analysis and CHAID analyses were performed on the consumers’ responses to determine sample groupings. Three clusters were identified among the consumers with positive opinions, enthusiastic, health-conscious, and unmotivated illustrating how the hierarchical level of preferences of the potential consumers of the red-fleshed apple fruit are triggered by various motivations. The surveys also pointed out that most consumers of the sampled population were not biased against research activities producing innovative food products. A large number of consumers, especially women, declared that they were willing to pay a higher price considering the increased nutritional value of red-fleshed apple fruits. By examining the broad context of this study, decision-making researchers and operators of the fruit industry will be able to make informed and realistic predictions concerning possible future scenarios and to determine the possible effects and desirability.     

Consumer Acceptance of Cloud Computing

To date, little research has focused on the consumer's perspective of cloud computing acceptance. Thus, this article explores the drivers of voluntary consumer acceptance of cloud computing in a sample of Moroccan students. Results indicate that in addition to ease of use and perceived usefulness, structural trust is important for voluntary cloud computing acceptance. However, unlike prior studies, results indicate that perceived ease of use has a stronger effect on intention to use cloud computing, than perceived usefulness. The results of this study contribute to theory and provide strategies for cloud computing service providers to attract and retain individual consumers.

Investigating the Drivers of Consumer Acceptance and Response of SMS Advertising

This study tests five potential drivers underlying the acceptance of SMS advertising. After developing a scale to measure behavioral responses to SMS advertising, the relationships between the acceptance of SMS advertising, intention to receive SMS advertising and behavioral responses to SMS advertising are tested. A convenience sampling method was employed. Survey questionnaires were distributed across Western Australia. The return yielded 203 usable questionnaires from the respondents. Several factors emerge as significant drivers of acceptance of SMS advertising including utility of SMS advertisements, context of SMS advertisements and attitudes to advertising in general. Contrary to expectation, control over SMS advertisements did not emerge as a significant driver for acceptance of SMS advertising. Trust in advertisers and laws did not emerge as a significant driver of the acceptance of SMS advertising among Australian respondents. Advertisers who pursue consumer acceptance should strive to build utility and context considerations into their SMS campaigns. Future research opportunities include testing the drivers of SMS advertising to further investigate the impact of control and trust on acceptance of SMS advertising in other countries where the SMS advertising has not been explored yet.     

Systems Mapping of Consumer Acceptance of Agrifood Nanotechnology

Application of nanotechnology in the agrifood system and the rising number of nanofood products on the market are creating concerns among consumers and other stakeholders. These concerns and other potential barriers to the commercialization of agrifood nanotechnology products may limit the ability to capture its full potential. Understanding the emerging trends and the links between underlying values, expressed attitudes, and actual behaviors involving consumer acceptance of agrifood nanotechnology is important for governance, risk regulation, and the achievement of the full potential of agrifood nanotechnology. The purpose of the study was to use systems mapping to examine and analyze critical links between consumer acceptance of agrifood nanotechnology and factors such as trust, stakeholders, institutions, knowledge, and human environmental health risks. The study used a meta-analysis of the risk perception literature and solicited the opinions of experts to develop the systems map. Factors affecting consumer acceptance of agrifood nanotechnology are dynamic, complex, interactive, and interdependent, and consumer decisions to accept agrifood nanotechnology were found to be the results of complex feedback structure. This study suggests several consumer policy and programmatic levels in the system toward enhancing consumer acceptance of agrifood nanotechnology products where warranted.     

Acceptance of recommendations to buy in online retailing

Nowadays, many online shops try to improve their customer service by personalization. Personal welcomings, individual assistance as well as recommendations to inform and buy are getting an integral part of the customer communication. These new elements are assumed to increase the retailer's share of wallet and – ideally at the same time – the customer's satisfaction with the online shop. However, till date only few studies have analyzed which external factors influence the customer's acceptance of such assistance. This paper closes this gap by an experiment, where a modified Technology Acceptance Model is used for measuring the customer's acceptance. Volunteers are offered an online shopping experience with individually generated recommendations to buy. The results show a high acceptance of the generated recommendations and how close this acceptance is connected to the quality and shopping relevance of the recommendations. Even though the results are limited to the specific recommendation types used, they give important implications for an adequate design of modern online shops.     

消费者接受促销背后的心理过程

促销是营销企图通过给予消费一些报偿,从而激起消费购买行动的一种说服的方法。促销的开支近20年来逐年增长,并且速度在加快,在许多消费包装品行业,促销支出已经远远超过了广告支出。1993年,麦当劳聘请名的好莱坞演员搞促销。结果销售增加了7．1％,达到142亿美元,而整个快餐业的增长率为6．6％。万事达信用卡采用折扣与折让促销。成功地停止了5年来市场份额不断下滑的趋势,     

Effects of Probability Markers on Advertising Claim Acceptance

The results of a laboratory experiment revealed that the participants had generally negative reactions to the use of hedges (e.g. ‘may’, ‘probably’, etc.) and pledges (e.g. ‘definitely,’ ‘undoubtedly’, etc.) in advertising claims. The use of either type of probability marker reduced claim acceptance and produced more negative cognitive responses relative to when no marker was used. This pattern of results emerged regardless of whether the claim was backed by an inductive argument presenting probabilistic evidence or a deductive argument presenting categorical evidence.
