Understanding OSS development in communities: the perspectives of ideology and knowledge sharing

This study aims to understand why open source software (OSS) developers contribute and how their dispersed efforts are controlled to lead to viable outputs. Drawing on theories related to ideology and information sharing, a model is proposed and tested empirically. We found that OSS values are positively associated with collaborative elaboration and communication competence, which in turn affect the performance of OSS task in terms of task completion. Our results also delineate the relationship among OSS norms, collaborative elaboration and source credibility, and task completion. This research contributes to advancing theoretical understanding of OSS performance as well as providing OSS practitioners with guidelines on how OSS communities use OSS ideology to achieve better performance.     

Gaming the system: The effects of social capital as a resource for virtual team members

Increasingly individuals interact with one another through information and communication technologies in virtual teams. Leveraging the resource-based view of the firm and social capital theory, we examine how a team member’s social capital (a resource) affects the team member’s perception of the quality of knowledge shared within the team (a capability) and the benefits to the individual team member (an outcome). Using the context of massively multiplayer online role-playing games, we find that within virtual teams, relational and cognitive social capital contribute to knowledge quality, which in turn positively benefits the outcomes of individual team members.     

The impact of the Abilene Paradox on double-loop learning in an agile team

This paper presents a qualitative investigation of learning failures associated with the introduction of a new software development methodology by a project team. This paper illustrates that learning is more than the cognitive process of acquiring a new skill; learning also involves changes in behaviour and even beliefs. Extreme Programming (XP), like other software development methodologies, provides a set of values and guidelines as to how software should be developed. As these new values and guidelines involve behavioural changes, the study investigates the introduction of XP as a new learning experience. Researchers use the concepts of single and double-loop learning to illustrate how social actors learn to perform tasks effectively and to determine the best task to perform. The concept of triple-loop learning explains how this learning process can be ineffective, accordingly it is employed to examine why the introduction of XP was ineffective in the team studied. While XP should ideally foster double-loop learning, triple-loop learning can explain why this does not necessarily occur. Research illustrates how power factors influence learning among groups of individuals; this study focuses on one specific power factor – the power inherent in the desire to conform. The Abilene Paradox describes how groups can make ineffective decisions that are contrary to that which group members personally desire or believe. Ineffective decision-making occurs due to the desire to conform among group members; this was shown as the cause of ineffective learning in the software team studied. This desire to conform originated in how the project team cohered as a group, which was, in turn, influenced by the social values embraced by XP.     

Modeling job effectiveness and its antecedents from a social capital perspective: A survey of virtual teams within business organizations

This study develops two alternative models concerning job effectiveness, knowledge sharing, and their antecedents related to individuals’ perception about their job effectiveness in a team. Model 1 of this study intends to be as parsimonious as theoretically justifiable. It posits that three dimensions of social capital - structural, relational, and cognitive social capital - simultaneously influence knowledge sharing and job effectiveness indirectly through the mediation of team commitment, while job effectiveness is also influenced by knowledge sharing. Based on Model 1, Model 2 further adds that knowledge sharing is influenced directly by three dimensions of social capital. The two models are tested by collecting data from professionals of virtual teams in high-tech industries. The test results support seven out of nine hypotheses in Model 2. Finally, managerial implications of the empirical findings are also discussed.     

The impact of intrinsic cognitive load on the effectiveness of graphical help for coherence formation

Learning with multiple representations requires the mental integration of corresponding information. This highly demanding process of coherence formation can, for example, be assisted by inter-representational hyperlinks, which foster the visual search for correspondences. In three studies we analyzed the effectiveness of hyperlinks depending on the amount of intrinsic cognitive load (ICL), which is on the one hand determined by the complexity of the learning task and on the other hand by the learners’ expertise. In the first two studies we varied the complexity of the integration task and found that the hyperlinks were only effective for the less complex task (low ICL). In the third study the amount of ICL has been varied by the level of expertise and the effects supported the previous outcomes: the help again was only effective in conditions of low ICL (higher expertise), whereas with high ICL (lower expertise) it was ineffective.     

Understanding the role of behavioural integration in ISD teams: an extension of transactive memory systems concept

The transactive memory system (TMS) has been considered as one critical element for effective teamwork. However, viewing TMS as a second‐order construct that mixes cognitive (specialty and credibility) and behavioural (coordination) components leads to confusion and increases the difficulty in interpreting study results. This study follows the concept proposed by one recent study and attempts to distinguish between behavioural and cognitive components. Furthermore, drawing on the need for diverse members to be integrated behaviourally, we also attempt to extend the TMS research stream by proposing a more comprehensive behavioural component of TMS. We argue that to obtain better teamwork outcomes, information system development (ISD) team members need to integrate the expertise possessed by each individual, make decisions jointly and interlink all individual actions. In light of this, our study aims to replace coordination with team behavioural integration, a more comprehensive behavioural consequence of cognition and explore the critical role of behavioural integration in ISD teams by understanding its impact on ISD teamwork project team performance. The study result, based on data collected from 205 information system project managers, supports our hypotheses that expertise specialty, credibility and their interaction positively affect team behavioural integration. This, in turn, leads to enhanced project team performance.     

Innovative Entrepreneurial Teams: The Give and Take of Trust and Conflict

Entrepreneurship research lacks empirical evidence about interactions between entrepreneurial team members . This paper examines the role of trust ( cognitive and affective ) and conflict ( task and relationship ) on team performance ( effectiveness and efficiency ) of innovative entrepreneurial teams . Data originated from 88 incubator‐based entrepreneurial teams in Austria . Results indicate that cognitive trust is the cornerstone of innovative entrepreneurial team performance . To maximize efficiency , such teams would rely on high cognitive trust and low task conflict . Nonetheless , the guidelines for being effective centre around high cognitive trust coupled with low task and relationship conflict .     

Coupled component modelling for inter- and transdisciplinary climate change impact research: Dimensions of integration and examples of interface design

In environmental research the importance of interfaces between the traditional knowledge fields in natural and social sciences is increasingly recognized. In coupled component modelling, the process of developing interface designs can support the communicative, social and cognitive integration between representatives of different knowledge fields. The task of integration is thereby not merely an additive procedure but has to be considered as important part of the research process. In our application, the development of a coupled component model facilitated an integrative assessment of the impact of climate change on snow conditions and skiing tourism in a typical Austrian ski resort. We elaborate the integration on two abstraction levels, a theoretical one and an applied one related to the case study. Other than model output, results presented here relate to the inter- and transdisciplinary development of the coupled component model and its interface design. We show how scientists from various disciplines and representatives from diverse societal fields jointly design interface tools. We identify joint model development – taking into consideration the different dimensions of integration – and recursive modelling as keys for successful inter- and transdisciplinary integration. Such integrative interface science can provide new insights which go beyond the sum of what can be learned from its disciplinary components.     

Why is Your Team More Creative Than Mine? The Influence of Shared Mental Models on Intra‐group Conflict,Team Creativity and Effectiveness

In competitive and dynamic contexts team members need to be creative to ensure that teams achieve high levels of performance and feel satisfied with their work. At the same time, team members need to have a shared understanding regarding relevant aspects related to task accomplishment and team interaction. In this study we investigate the mediating mechanisms of intra‐group conflict and creativity in the relationship between shared mental models and team effectiveness (team performance and satisfaction). We tested our model in a sample of 161 teams (735 individuals) performing in a management simulation. We collected data at three time points. Our results suggest that high shared mental models are related to low levels of intra‐group conflict, foster creativity, and in turn improve team performance and satisfaction. These findings contribute to a scarce thematic – the relationship between shared mental models and creativity – emphasizing the importance of a shared understanding for creativity and team effectiveness.     

Does social capital matter? A quantitative approach to examining technology infusion in schools

Changing teachers’ perceptions about the value of technology and equipping them with appropriate knowledge and skills in pedagogical use of technology is often regarded as a key determinant of success in technology infusion in schools. However, recent studies have indicated that changing teachers’ epistemological beliefs about the use of technology in teaching and learning may not necessarily bring about change in their practice, and that technology implementation in schools can be affected by other instrumental forces, such as collegial trust, support for risk taking and access to expertise within an organization. In this article, we delineate collegial trust, access to expertise, willingness to take risks, etc. as manifestations of social capital in an organization. We argue that social capital plays a pivotal role in leveraging pedagogical change in schools. To gauge teachers’ self‐perceived change in their pedagogical use of technology, we take a constructivist perspective to explore how technology serves as a tool for facilitating students to articulate their thoughts, to explore and construct knowledge, and to become more autonomous in learning. The results of our questionnaire survey indicate that (1) the social capital of a school had a strong direct effect on teachers’ self‐perceived changes in their pedagogical use of technology, and that the effect of social capital on pedagogical change outweighed that of teachers’ perceived effectiveness of professional development; (2) teachers’ receptivity towards technology use had a direct effect on their perceived effectiveness of professional development but a very weak effect on fostering changes in their pedagogical use of technology; and (3) the social capital of a school had a direct influence on teachers’ receptivity towards technology use and their perceived effectiveness of professional development. To further unfold the complexity of technology implementation, more in‐depth qualitative studies on how social forces shape the change process are deemed necessary.     

Network ties and the success of open source software development

Prior network-based research on open source software (OSS) development has focused on the benefit of network ties and assumed all network ties play the same role. We adopt a fine-grained view of network relations to investigate the impact of network ties on the success of OSS development. Through examining the development of OSS projects hosted by SourceForge, we find that co-membership among project teams is an effective mechanism for building network ties, through which knowledge and expertise flows across projects in OSS community and, therefore, contributes to the success of OSS development. However, network ties among projects not only confer benefit, but also incur various cost, and due to the different growth patterns of cost and benefit, network ties have a diminishing return to project success. In addition, we find network ties of leader–follower type and follower–leader type are more beneficial to OSS success than other types of ties, and network ties connecting to projects of later development stages are more beneficial than those connecting to projects of earlier stages. Our study provides useful guidelines and suggestions as to how to leverage the knowledge and expertise of others for successful development of OSS projects.     

Investigating the defect detection effectiveness and cost benefit of nominal inspection teams

Inspection is an effective but also expensive quality assurance activity to find defects early during software development. The defect detection process, team size, and staff hours invested can have a considerable impact on the defect detection effectiveness and cost-benefit of an inspection. In this paper, we use empirical data and a probabilistic model to estimate this impact for nominal (noncommunicating) inspection teams in an experiment context. Further, the analysis investigates how cutting off the inspection after a certain time frame would influence inspection performance. Main findings of the investigation are: 1) Using combinations of different reading techniques in a team is considerably more effective than using the best single technique only (regardless of the observed level of effort). 2) For optimizing the inspection performance, determining the optimal process mix in a team is more important than adding an inspector (above a certain team size) in our model. 3) A high level of defect detection effectiveness is much more costly to achieve than a moderate level since the average cost for the defects found by the inspector last added to a team increases more than linearly with growing effort investment. The work provides an initial baseline of inspection performance with regard to process diversity and effort in inspection teams. We encourage further studies on the topic of time usage with defect detection techniques and its effect on inspection effectiveness in a variety of inspection contexts to support inspection planning with limited resources.     

The influence of screen size and text layout on the study of text

This study investigates the effects of screen size (12 inch versus 15 inch) and text layout (well structured and ill structured) on the learning of text presented on the monitor of a personal computer. Two aspects of learning are assessed. A summary and a multiple-choice test are employed to measure the amount of information retained. Efficacy of learning is assessed by learning time and by cognitive effort, as measured by the performance on a secondary task. The results indicate that neither screen size nor text layout has a significant influence on the required cognitive effort or on the amount of information acquired. There is, however, a significant (main) effect of screen size on learning time: subjects using a 15 inch screen need less learning time than subjects using a 12 inch screen, with no difference in learning performance. It is suggested that more efficient integration processes in constructing the semantic representation are responsible for this reduction in learning time. Implications for future research are discussed.     

A theory-grounded framework of Open Source Software adoption in SMEs

The increasing popularity and use of Open Source Software (OSS) has led to significant interest from research communities and enterprise practitioners, notably in the small business sector where this type of software offers particular benefits given the financial and human capital constraints faced. However, there has been little focus on developing valid frameworks that enable critical evaluation and common understanding of factors influencing OSS adoption. This paper seeks to address this shortcoming by presenting a theory-grounded framework for exploring these factors and explaining their influence on OSS adoption, with the context of study being small- to medium-sized Information Technology (IT) businesses in the U.K. The framework has implications for this type of business – and, we will suggest, more widely – as a frame of reference for understanding, and as tool for evaluating benefits and challenges in, OSS adoption. It also offers researchers a structured way of investigating adoption issues and a base from which to develop models of OSS adoption. The study reported in this paper used the Decomposed Theory of Planned Behaviour (DTPB) as a basis for the research propositions, with the aim of: (i) developing a framework of empirical factors that influence OSS adoption; and (ii) appraising it through case study evaluation with 10 U.K. Small- to medium-sized enterprises in the IT sector. The demonstration of the capabilities of the framework suggests that it is able to provide a reliable explanation of the complex and subjective factors that influence attitudes, subjective norms and control over the use of OSS. The paper further argues that the DTPB proved useful in this research area and that it can provide a variety of situation-specific insights related to factors that influence the adoption of OSS.     

Antecedents of Team Creativity: An Examination of Team Emotional Intelligence,Team Trust and Collaborative Culture

Teams represent a dominant approach to getting work done in a business environment. Creativity enables teams to solve problems and leverage opportunities through the integration of divergent thoughts and perspectives. Prior research indicates that a collaborative culture, which affects how team members interact and work together, is a critical antecedent of team creativity. This study explores other antecedents of team creativity, namely, team emotional intelligence and team trust, and investigates the relationships among these precursors to creative effort. Using a survey of 82 student teams at a large university in the northeast United States, our findings suggest that team emotional intelligence promotes team trust. Trust, in turn, fosters a collaborative culture which enhances the creativity of the team. Cognitive trust also moderates the relationship between collaborative culture and team creativity. Implications of these results for managers and academics are discussed.     

A preliminary investigation of information systems team structures

Productivity in the information age is widely perceived to be a major organizational problem. One strategy for enhancing organizational productivity has been the use of task teams. Assignment to task teams is usually based on individual technical expertise, individual availability, and/or positional politics rather than on the effectiveness of the team members in the specific organizational situation. This paper investigations characteristics of team members and then examines the effect of these characteristics and the requirements of the organizational task on team effectiveness.The findings indicate that the perceptual types of team members and the task structure impacts team effectiveness. It lends evidence that heterogeneity of perceptual types is best for solving unstructured tasks whereas heterogeneity can be counter-productive when solving structured tasks. It also suggests that one team might not be appropriate for all stages of a project. As the structure of the tasks change, the optimum team composition might also change.     

Does social capital affect SNS usage? A look at the roles of subjective well-being and social identity

This study views social capital as a precursor of SNS (Social Network Service) use, which departs from the previous thoughts that considered social capital as the outcome of SNS activities. Drawing upon the theoretical premises regarding network-based social capital, this study examines the roles of subjective well-being and social identity in terms of their moderating as well as mediating influences on SNS use. This study sought to sub-categorize social capital and SNS use with a view to providing more refined theoretical and practical implications. The study’s main objectives are three-fold: First, the study verifies whether social capital, categorized into bridging and bonding capital, influences one’s SNS use as measured by qualitative use and quantitative use. Second, the study aims to confirm whether subjective well-being mediates between social capital and SNS use. Third, it examines whether social identity moderates the relationship between social capital and SNS use.The study result indicates that bridging capital only had a significant impact on qualitative use. However, subjective well-being did not mediate the relationship between social capital and SNS use. Finally, the cognitive identity caused significant difference in the effect of social capital on quantitative SNS use, whereas cognitive and affective identities caused significant differences in regards to the effects of bridging capital on qualitative SNS use.     

How Team Identification and Expertise Identification Affect R&D Employees' Creativity

The relationship between team identification and expertise identification in the R&D context and the mechanism by which these variables influence R&D creativity is not yet clear. We present and empirically test a theoretical framework proposing that knowledge sharing mediates the relationship between identification and creativity in R&D teams. Based on 120 paired‐sample survey data of 30 R&D teams, we show that knowledge sharing mediates the relationship between team identification (but not expertise identification) and R&D team members' creativity. Contributions to the literature and the practice of innovation and R&D management, knowledge and creativity management, and team management are discussed.     

Understanding buyers' loyalty to a C2C platform: the roles of social capital,satisfaction and perceived effectiveness of e‐commerce institutional mechanisms

Drawing upon social capital theory, this study aims to investigate how different dimensions of social capital affect online buyers' satisfaction and ultimately boost their loyalty to a Consumer‐to‐Consumer (C2C) platform. Specifically, we propose that three dimensions of social capital (i.e., cognitive, structural and relational capital) contribute positively to the two types of online buyers' satisfaction (i.e., economic and social satisfaction). In addition, we posit that perceived effectiveness of e‐commerce institutional mechanisms (PEEIM) moderates the relationships between economic and social satisfaction and buyers' loyalty to the platform. Three hundred buyers on the Consumer‐to‐Consumer platform, TaoBao, were surveyed to test the proposed model. The results suggest that buyers' evaluation of social capital with the community of sellers can enhance their satisfaction with the sellers, which subsequently affect their loyalty to the platform. Furthermore, perceived effectiveness of e‐commerce institutional mechanisms negatively moderates the effect of economic satisfaction and positively moderates the effect of social satisfaction on buyers' loyalty to the platform. The theoretical contributions and practical implications are discussed.     

Relative effectiveness of animated and static diagrams: An effect of learner prior knowledge

This paper investigates the relationship between instructional effectiveness of animated vs. static diagrams and levels of learner expertise in the task domain of transforming graphs of simple linear and quadratic functions. It was demonstrated on many occasions that instructional formats that are effective for low-knowledge learners could be ineffective, or even deleterious, for high-knowledge learners, and vice versa (the expertise reversal effect). The levels of learner (university students) expertise in this study were measured using an online rapid diagnostic method, a rapid verification technique, that involves presenting learners with a series of possible solution steps reflecting various stages of the solution procedure and asking them to rapidly verify the suggested steps. The results indicated a significant interaction between levels of learner expertise and instructional formats. Novice learners benefited more from static diagrams than from animated diagrams, while more knowledgeable learners benefited more from animated rather than static diagrams. A theoretical explanation of the effect is suggested within the framework of cognitive load theory.
