The effect of service employees’ technology readiness on technology acceptance

As much of the work of service employees is supported by IT, the quality of the service often depends on how the technology is used. Most employees only use a fraction of the functionality available on their desk-top. This may also depend on their personality. We performed research on the relationship of personality and technology acceptance.     

Service robots in hospitals: new perspectives on niche evolution and technology affordances

Changing demands in society and the limited capabilities of health systems have paved the way for robots to move out of industrial contexts and enter more human-centered environments such as health care. We explore the shared beliefs and concerns of health workers on the introduction of autonomously operating service robots in hospitals or professional care facilities. By means of Q-methodology, a mixed research approach specifically designed for studying subjective thought patterns, we identify five potential end-user niches, each of which perceives different affordances and outcomes from using service robots in their working environment. Our findings allow for better understanding resistance and susceptibility of different users in a hospital and encourage managerial awareness of varying demands, needs, and surrounding conditions that a service robot must contend with. We also discuss general insights into presenting the Q-methodology results and how an affordance-based view could inform the adoption, appropriation, and adaptation of emerging technologies.     

Studying the effect of perceived hedonic mobile device quality on user experience evaluations of mobile applications

When people interact with digital artefacts they perceive their pragmatic and hedonic qualities. In the case of interacting with mobile devices and applications, users seek utility as they try to satisfy certain needs, but at the same time they have certain feelings and emotions when, for example, they feel attached to their personal phone and/or trust its brand. Due to this strong relation between users and mobile devices a significant problem occurs when researchers want to evaluate the user experience of a mobile application in laboratory settings: the selection of an appropriate mobile device. Towards this end, this paper aims to unveil the effect of perceived hedonic quality of a mobile device on the user experience evaluation results of an application. Our results show that the perceived hedonic quality of a mobile device significantly affected the perceived pragmatic quality of the application, but not the hedonic one.

Leveraging the affordances of Youtube: The role of pedagogical knowledge and mental models of technology functions for lesson planning with technology

Web-based digital video tools enable learners to access video sources in constructive ways. To leverage these affordances teachers need to integrate their knowledge of a technology with their professional knowledge about teaching. We suggest that this is a cognitive process, which is strongly connected to a teacher’s mental model of the tool’s affordances. First we elaborate the theoretical integration of the notion of mental models and the Technological Pedagogical Content Knowledge (TPCK) framework. Then we report on a study where we investigated pedagogical knowledge in a sample of German pre-service teachers as a predictor for their mental models of YouTube and how these affect lesson plans for instructional use of this technology. We describe the active mental models of YouTube and present quantitative analyses suggesting mental models as mediators for the influence of pedagogical knowledge on participants’ lesson planning. Results are discussed with regard to theoretical and research implications.     

Educational affordances of PDAs: A study of a teacher’s exploration of this technology

This paper reports on a case study of a teacher from a technical education institution who explored the educational affordances of PDA technology over a period of six months. Based on this teacher’s perspectives, the study was designed to inform our own understanding of educational affordances of this new and emerging technology. Understanding of educational affordances is important in the context of planning a suitable intervention to support pedagogically effective integration of PDA technology. The study explicated a set of five affordances of PDA technology: as a multimedia-access tool, connectivity tool, capture tool, representational tool and analytical tool. We call on further research to expand this set into a more comprehensive collage of educational affordances of PDA technology.     

服务流程检索技术研究

服务重用的目的是提高软件开发的效率,然而,现有的服务重用方法局限于原子服务的重用。如何重用任意粒度的服务流程片段（Service Flow Fragment,SFF）是一个更具实用价值的问题。提出一种新颖的索引（Changeable Level Index,CLI）,它通过所构造的服务标签合并树（Service Label Merge-tree,SLM-tree）组织服务流程,同时实现原子服务及组合服务的检索,从而最大限度地提高它们的利用率,并且能够择优返回检索结果。为验证所提出方法的可行性和有效性,通过Web Service Challenge Testset Generator（CTG）构造了一个包含20万流程,1.05亿原子服务的数据集。实验结果表明,提出的方法具有很高的性能。

Motivated by the phenomenon of customer entrepreneurship in China and the associated research gaps, we conduct a case study to explore how customer entrepreneurs realize benefits from light entrepreneurship enabled by guanxi circles and social commerce affordances. Our study derives a process model that describes how customer entrepreneurs benefit from light entrepreneurship through acquiring knowledge and sharing knowledge within guanxi circles embedded in social media. We also demonstrate the roles of the mass entrepreneurship climate and the social commerce affordances in this benefit realization process. This study contributes to the research and practice with respect to technology-enabled customer entrepreneurship.

Disengaged students and dialogic learning: the role of CSCL affordances

Only a few studies have dealt with the challenge of bridging the linguistic gap between the dialogic realm and the talk of disengaged students. Bridging this gap is particularly relevant to the CSCL community since one of its utmost aims is to promote the dialogic. This study aims to articulate how to harness the CSCL design and affordances to enhance dialogic pedagogy with disengaged students. Using temporal analysis of philosophical discussions for children, we focus on three disengaged 8th grade students participating in successive discussions mediated by a CSCL tool (Argunaut), and follow the way they talk with their peers in the classroom. The study shows the gradual emergence of the dialogic among those students. We describe the transition of their talk moves, from initially reproducing the way they talk to adopting dialogical norms. To explain this we conceptualize the notion of carriers of discursive norms and discuss its transformative role in dialogue. The dialogic transition was made possible by the pedagogical design and the design of the CSCL tools. These affordances allowed the students change the meaning of the conversational building blocks of space, silence, addressee, and the ethics of talk.

基于语义的Web服务发现技术研究

针对现有基于语义的服务发现机制普遍对服务质量描述和服务分类考虑不够,以及匹配机制适应范围较窄、匹配效率较低的问题,进行了服务描述与服务发现技术的研究,对OWL S规范作了一定的补充,并提出了一种基于语义的服务发现算法。以树形结构描述Web服务,按照一定策略对节点赋予不同的权值并分类存储。在服务匹配时,首先对服务请求进行预处理和领域定位,然后利用基于WordNet和HowNet的语义相似度计算方法以及一定的辅助技术实现服务匹配。实验结果表明,该服务匹配算法具有较好的查准率和查全率。
