A Systematic Procedure for Modeling Usability Based on Product Design Variables: A Case Study in Audiovisual Consumer Electronic Products

A systematic modeling approach to describing, prescribing, and predicting usability of a product has been presented. Given the evaluation results of the usability dimension (UD) and the measurement of the product’s design variables, referred to as the human interface elements (HIEs), the approach enables one to systematically assess the relationship between the UD and HIEs. The assessed relationship is called a usability model. Once built, such a usability model can relate, in a quantitative manner, the HIEs directly to the UDs, and thus can serve as an effective aid to designers by evaluating and predicting the usability of an existing or hypothetical product. A usability model for elegance of audiovisual consumer electronic products has been demonstrated.

基于消费者行为模型的农村居民环境保护意愿分析

针对农村居民基于消费者行为的环境保护意识构建经济模型,将居民消费品分为环境关联物品和非环境关联物品两类,又从环境关联物品中分离出环境友好型商品和环境负效应商品,对这两种消费品抽象出某种效用层次下两种类型商品的组合,通过规范式分析方法,判断农村居民环境保护意愿的影响因素和规律。结论显示,农村居民环境保护意愿的不断提高,需要绿色消费品相对价格的降低;通过加大宣传教育,使他们的环保意愿与行为选择达到对农村自然环境保护更为理想的状况。

Competition between Populations in the Consumer–Producer Trophic Chain in a Closed Aquatic System

The functioning of a closed aquatic consumer–producer system with spatially separated links, with each link consisting of two species, is considered. Competition between the consumers (infusorians Paramecium caudatum and rotifers Brachionus sp.) feeding on a mixed algal culture (Chlorella vulgaris and Scenedesmus sp.) and competition between these algae under conditions of limited nitrogen supply are analyzed. It is shown that Scenedesmus algae have an advantage over C. vulgaris in terms of competitiveness, and their metabolic products have an adverse effect on reproduction in infusorians.

An exploration of firms’ awareness and behavior of developing circular economy: An empirical research in China

Despite the wealth of information concerning environmental awareness and the behavior of firms, there is little empirical research on the awareness and behavior of firms in developing the circular economy. The study employed a questionnaire survey and in-depth interviews with 157 firms from manufacturing clusters in China. Results indicated that the firms had a relatively good understanding about the circular economy and its values and had a strong willingness to operate a circular economy, but this was not indicative of enthusiastic behavior. A striking “gap” existed between a firm's awareness and its actual behavior in developing a circular economy. Reasons for the gap are explored mainly based on the results of interviews. Finally, recommendations for overcoming the gap between the awareness and behavior are suggested.     

基于“3A”理论的高职高专院校学生英语学习的研究

结合英语教学实践,依据Leo van Lier的意识原则(Awareness)和自主性原则(Autonomy),对高职高专院校英语专业学生进行了问卷调查。调查结果显示,高职高专院校英语专业学生的英语学习意识薄弱,动机不强。3A理论的启示是:发挥学生的主体作用,树立学生的语言学习意识,调动学生学习英语的主观能动性。

Perception,knowledge and attitude towards environmental issues and management among residents of Al-Suwaiq Wilayat,Sultanate of Oman

The purpose of this study was to determine residents’ perception, knowledge and attitude towards environmental issues and management in the Al-Suwaiq Wilayat (administrative zone) of Al-Batinah North, Sultanate of Oman. For this purpose, a questionnaire was used with questions on issues related to environment and surveyed across 109 households in the Wilayat following a random sampling method in early 2015. The results show that education, health-related infrastructure and unemployment are ranked as most important issues for government attention today and in coming 10 years besides their concern for the environment. Resident’s perceptions on most important environmental issues were concerned about solid-waste pollution, degradation of coastal areas, saltwater intrusion and land degradation. The sources for environmental information, government agencies, local media and schools were regarded as most reliable. Top environmental priorities were suggested to deal with enforcement of regulations, provide effective environmental awareness and education programs. Further, it is suggested that additional studies should be conducted such as ‘State of Environment Reporting’, thereby such reporting, for instance would provide some form of verification of reported behaviour and improved knowledge.
