资本禀赋、感知价值、政府补贴对农户清洁取暖采纳行为的影响

农户清洁取暖采纳行为是实现农村散煤长效治理和能源结构可持续变迁的关键。为系统阐释农户清洁取暖采纳行为机理,本文基于汾渭平原农户调查数据,采用二元Probit和OLS计量方法实证分析了资本禀赋、感知价值与政府补贴对农户清洁取暖采纳行为的影响。结果显示：①作为一组结构性要素资源,资本禀赋反映了农户“能力大小”;作为一套感知评价系统,感知价值反映了农户“有心程度”;当农户“既有心又有力”时,采纳清洁取暖的行为趋向性更明显。②作为清洁取暖采纳的实际行动者,农户的主体性作用十分重要。如果没有资本禀赋等结构性要素资源的支撑,农户大概率不会实施清洁取暖;同时,如果没有农民自发自觉地实施收益要求与成本风险规避考量形成的感知价值判断,结构提供的资源也难以转化为清洁取暖的具体行动,即感知价值在资本禀赋与农户清洁取暖采纳行为间的中介作用存在。③作为一项激励机制,政府补贴可以通过强化农户清洁取暖利益感知、缓解农户清洁取暖成本与风险压力感知,进而正向调节感知价值与农户清洁取暖采纳行为间的影响关系。据此,本文提出了促使农户资本禀赋积累、提升农户清洁取暖感知价值以及落实政府补贴的政策建议。     

e-Government adoption model based on theory of planned behavior: Empirical validation

The e-Government phenomenon has become more important with the ever increasing number of implementations worldwide. A model explaining the e-Government adoption and the related measurement instrument – a survey – had been developed and validated in this study. In a post Technology Acceptance Model (TAM) approach, theory of planned behavior (TPB) was extended to fit the requirements of e-Government context. The adoption of student loans service of the higher education student loans and accommodation association of Turkey (KYK) was investigated to obtain data for empirical validation. The instrument was administered to over four-hundred students and partial least squares path modeling was employed to analyze the data. The results indicate that the model was an improvement over TAM in terms of predictive power. The constructs trust, perceived behavioral control and attitudes successfully explained the intention to use an e-Government service. The findings presented in this study provide useful insights for researchers and policy makers when dealing with e-Government services.

我国现行收养制度由于收养关系建立的随意性、收养效果的不稳定性等弊端 ,不能充分体现收养制度的本来目的。建立我国特别收养制度很有必要 ,主要应解决如下问题 :限制特别收养关系主体范围 ,严肃特别收养关系成立的形式 ,强化特别收养关系的效果。     

信息系统采用模型的比较研究

信息系统采用是信息系统研究领域中一个极为重要的话题。其研究主要集中在认知行为模型的探讨方面，试图寻求一种理想的模型来解释人们为什么接受新的系统或技术。本文详细论述了三种常用的模型——理性行为理论、技术接受模型和计划行为理论，并对这三种模型进行了比较，在此基础上指出了未来研究的发展方向。     

Adoption of Agri-Environmental Measures by Organic Farmers: The Role of Interpersonal Communication

Purpose: The purpose of this study is to investigate the impact of interpersonal communication on the adoption of agri-environmental measures (AEM) by organic farmers in Germany.

Methodology: The study used the logit model to predict the probability of adoption behaviour, and Social Network Analysis (SNA) was conducted to analyse the question of whether validating information about organic farming provided by interpersonal information sources is associated with communication frequency.

Findings: Our findings demonstrate that being an early adopter of organic farming practices and frequent contact with young and highly educated farmers increases the probability of adoption of other AEM. However, contact frequency in interpersonal networks was found not to be a significant determinant for explaining adoption decisions. Frequently communicating farmers in the network are more likely to attribute higher levels of importance to organic farming information received from formal actors than to information received from informal actors.

Practical Implications: If young and highly educated farmers, who can be considered as informal opinion leaders, are approached by the extension services, then an effective diffusion of information on AEM can be expected. To support the AEM adoption, a platform should be provided by state agencies that would enable organic farmers to understand the environmental benefits achieved over the time.

Originality/value: This study contributes to the scientific discussion on the role of interpersonal communication on AEM adoption. A new aspect is our consideration of organic farmers adopting additional AEM. Moreover, we highlight organic farmers' validation of the importance of formal and informal information sources on organic farming.     

Extending the understanding of mobile banking adoption: When UTAUT meets TTF and ITM

Mobile banking (mBanking) enables customers to carry out their banking tasks via mobile devices. We advance the extant body of knowledge about mBanking adoption by proposing a model for understanding the importance and relationship between the user perception of mBanking, initial trust in mBanking services, and the fit between the technology and mBanking task characteristics. We synergistically combine the strengths of three IS theories – task technology fit (TTF) model, unified theory of acceptance and usage of technology (UTAUT), and initial trust model (ITM). The model was tested in a study conducted in Portugal, one of the European Union (EU) countries with the highest mobile phone adoption. Based on the sample of 194 individuals we applied partial least squares (PLS) to test the conceptual model propose. The path significance levels were estimated using the bootstrapping method (500 resamples). The study found that facilitating conditions and behavioral intentions directly influence mBanking adoption. Initial trust, performance expectancy, technology characteristics, and task technology fit have total effect on behavioral intention. The paper offers valuable insights to decision-makers involved in the implementation and deployment of mBanking services. For researchers, the paper highlights the usefulness of integrating TTF, UTAUT and ITM in the development of a decision support framework to study the adoption of new technologies.     

影响员工接受移动商务应用因素研究

基于社会认知理论,从移动商务在企业内部使用的分析角度,提出影响员工使用移动应用的认知因素模型．在该模型中,移动工作者的自我效能作为主要因素,是指其评估自己使用移动技村应用完成工作任务的能力,而使用经验、同事和组织支持将直接影响移动工作者自我效能,增强或降低员工的自我效能,从而使员工期望使用移动技术带来结果发生变化,产生不同影响情绪反应．移动工作者自我效能的程度高,会提高移动商务在企业内应用程度．通过一个移动商务实际应用案例分析,对提高移动商务在企业内部实际应用程度,给出相应建议．     

Student Technology Rollouts in Higher Education: Lessons From DISCOVERe

ICT rollouts are no longer discretionary: they have become a mandatory function of effective educational institutions. This study examines the rollout of tablet technology at a public, four-year university with particular attention to variations within the student population and the student voice. The research questions included: Do expectations about new technologies vary among students according to socioeconomic factors? If expectations vary, then how do variations within the student population affect student response to ICT rollouts in higher education? Can attention to the student voice, including any variations within the student population, help higher educational institutions field more successful technology rollouts? The study found significant variation among students in the factors affecting technology adoption, which in turn affected the way the rollout was received by students. The study points to ways attention to the student voice can positively inform future technology rollouts.     

《爨宝子碑》和《爨龙颜碑》中疑难字形考释

两爨碑是研究爨文化的重要依据,但两碑文字异体繁杂,别体难辨,专家学者的考释多有出入。对这些出入的文字进行考证,可以使释文更接近于原作者所要表达的意思,也能更真实地再现爨氏统治南中时代的历史,这对今天研究爨文化无疑是一种推动的工作。
