Abstract
Purpose
To create the expected value and benefits through open data, appropriate provision and usage of data are required simultaneously. However, the level of provision and usage of open data differs from country to country. Moreover, previous research on open data has only focused on either open data provision or usage. To fill the research gap, the purpose of this paper is threefold: first, to understand the current status of the provision and usage of open data; second, to identify patterns in the provision and usage of open data; and third, to provide appropriate future directions and guidelines for the transformation paths of each pattern.
Design/methodology/approach
The authors analyzed the data collected from open data portals of 13 countries that provide information on the provision and usage of open data together.
Findings
The authors identified four patterns of the provision and usage of open data, namely, availability-driven, government-driven, market-driven and interaction-driven patterns. Furthermore, three strategic paths of transformation reach a high level of open data provision and usage, namely, data provision-focused, data usage-focused and balanced transformation paths.
Originality/value
This study provides a foundation that enables researchers to build a holistic theory that can integrate fragmented and incomplete knowledge of open data and usage, particularly in the context of government.

Abstract
Purpose
The authors use the extension mechanism provided by the Business Process Model and Notation (BPMN) to define roles, which allows roles to be fully aligned with the BPMN standard. The authors describe how a pattern can be defined in terms of roles and present the formal semantics of pattern realization and refinement to support systematic reuse of patterns in business process development.
Design/methodology/approach
It is widely agreed that the use of business process patterns improves the efficiency and quality of business process development. However, few techniques are available to describe business process patterns at an appropriate level of abstraction to facilitate the reuse of patterns. To address this, this paper presents the role-based Business Process Model and Notation (R-BPMN), an extension of BPMN for abstract modeling of business process patterns based on a novel notion of role.
Findings
The authors apply R-BPMN in case studies for pattern realization and refinement and discuss tool support via an existing tool. The case studies demonstrate the practical benefits of R-BPMN in capturing pattern variability and facilitating pattern reuse.
Practical implications
The findings imply a potential impact of R-BPMN on practical benefits when it is supported at the metamodel level in tool development.
Originality/value
This study addresses the need for abstract modeling of process patterns at the metamodel level, which facilitates the formalization of pattern variability and tool development to support various realizations of process patterns at the model level.

Abstract
Purpose
The purpose of this paper is to examine considerations employed in decision-making processes by Israeli high school leaders, when implementing the “Courage to Change” reform. The reform gave schools large supplementary resources in the form of “weekly instruction time” and they decided how to exploit these additional hours.
Design/methodology/approach
Qualitative analysis focused on data from interviews with staff from 19 high schools.
Findings
The research identified three types of consideration adopted by managerial staffs: “Hasty,” “Conservative” and “Path-breaking.” Findings contribute to theory concerning incremental decisions in schools concerning the allocation of resources, in line with the institutional approach, and also inform other schools coping with similar tasks.
Originality/value
The research is original both in its topic and context. Further conclusions and implications are discussed.

Abstract
Purpose
The purpose of this paper is to understand how social enterprises (SEs) sustain social focus as they shift their legal format from nonprofit to for-profit. The investigation is driven by the understanding that historical persistence of organizational action can influence the sustenance of social focus.
Design/methodology/approach
The paper uses a case study approach and traces the commercialization process of two microfinance organization from India. The data come from interviews and archival documents spanning across the biography of the selected organizations. The constitutive elements of the commercialization process are identified by using the lens of path creation.
Findings
Evidence suggests that the framing of purpose for microfinance as empowerment of women formed the triggering event to path creation. The organizations retained the focus on social goal by adopting a community centered delivery model of self-help groups. The organizational practices adopted after commercialization helped these organization to address the issues of drift actively.
Research limitations/implications
The paper suggests that framing of organizational purpose can play a crucial role in sustaining hybrid character in SEs. It reinforces earlier findings that stakeholders can exert significant influence in balancing social and commercial goal. The aspiration to be identified as a pro-community organization is another critical driver in sustaining social focus. Finally, for SEs to sustain their social focus, proactive engagement with the community should become an integral part of organizational practices.
Originality/value
The paper explores the constitutive elements of path creation and demonstrates the sustenance of social focus through three stages of organizational path development. It also offers insights into the literature on historical imprinting by exploring the internal process through which imprinting is sustained and amplified and by presenting sources and outcome of imprinting.

Abstract
Purpose
This study aims to explore the nature of women's career experiences over the life course by examining career patterns, career locus, career contexts, and career beliefs.
Design/methodology/approach
A qualitative, inductive approach to data gathering and analysis was employed, using life story surveys, semi‐structured interviewing, thematic analysis, grounded theory, code development and descriptive statistics.
Findings
The data revealed distinct patterns of how women's careers develop over time, particularly with regard to the impact of career contexts (societal, organizational, and relational) and women's own changing images of their careers and career success. A three‐phase, age‐linked model of women's career development is proposed: the idealistic achievement phase; the pragmatic endurance phase; and the reinventive contribution phase.
Research limitations/implications
Future studies should test replicability of these findings to determine whether this three‐phase model is embedded in the particular socio‐historical context of the times in which the particular women in this sample have lived or is universally applicable across different eras and changing realities.
Practical implications
Better organizational efforts are needed to ensure that women receive ongoing coaching and mentoring, work for managers who support their development, have access to organizational resources and opportunities to develop their skills, are given challenging assignments, are acknowledged for their unique talents, and are recognized for aptitude learned through life experiences and “non‐traditional” work histories.
Originality/value
This is a rare, women‐only study that looks at the career dynamics of women over the life course.

Abstract
Purpose
The purpose of this paper is to discuss the development of high‐tech industry and the dynamics of technological learning, innovation, entrepreneurship in China through the telecom‐equipment industry.
Design/methodology/approach
The paper derives a number of research propositions from the literature and then uses four case studies to show how domestic firms narrow their technological gap in different stages of catch‐up and how these firms have been influenced by their innovation capabilities to catch up to the multinationals.
Findings
The major findings of the paper may be summarized as follows. First, the innovation capability and self‐developed technologies have been the key to leading domestic firms in catching‐up with the MNCs. Second, leading domestic firms mainly depend on in‐house R&D development, supplemented with external alliance to build their innovation capability. Third, there are two different catching‐up patterns in China's telecom‐equipment industry. One is “path‐following” catching‐up in global system for mobile communication driven by using new technology in low‐end market. The other is “leapfrogging” catching‐up in the development of phone digital switches and China's own 3G standard (time division – synchronous code division multiple access). However, it seems that the leapfrogging strategy will meet more challenges and problems than the path‐following strategy.
Originality/value
Based on the previous researches about technological learning, innovation and catch‐up in the newly industrializing economies, the paper provides a comprehensive elaboration in Chinese telecommunication industry by using case study approach in an original way.

Abstract
Purpose
The purpose of this paper is to demonstrate System-of-Systems (SoS) approach to design and development of unmanned robotic platform for greenhouse agricultural application.
Design/methodology/approach
SoS design approach is important in developing engineering products. It was observed that while system integration considers designs in a multi-disciplinary level framework, SoS is viewed as a solution focussed approach. In this paper, the authors have demonstrated SoS approach to develop a mobile robot platform. The wheels of the platform are independently controlled by using brushless DC and stepper motors based on fieldbus type Distributed Control System scheme.
Findings
The constraints for autonomous traveling were identified during the first phase followed by development of 12 distinct sub-routines during second phase of training. Optimal camera installation angle, driving speeds, steering angle per pixel were found to be valuable constraints for feed-forward parameters for real-time driving. The platform was field tested in a tomato planted greenhouse for yield and weed mapping.
Research limitations/implications
The paper focusses on studying vision-based autonomous four-wheel-drive (4WD) constraints and their implementation limitations.
Practical implications
The platform was field tested in a tomato planted greenhouse for yield and weed mapping.
Social implications
The platform can be used for agricultural operations such as crop scouting, monitoring, spraying, and mapping in a medium to large-scale greenhouse setting.
Originality/value
The research and presentation is original. Starting from its mechanical specification to wheel performance study, development of path patterns for training and global navigation algorithm for testing and validation were achieved. The platform can autonomously be driven without any manual intervention.

Abstract
Purpose
This study explores how entrepreneurs modify their financial path(s) and go beyond job security to attain greater financial freedom. The present work examines the cash-flow quadrant (CFQ) attributes and demonstrates the importance of the push-pull factors for an individual's quadrant transition in achieving financial freedom.
Design/methodology/approach
A hypothetical model and an abductive approach were used through regression models in a population sample of 260 Bahraini entrepreneurs. Fuzzy participatory cognitive mapping was also used to develop a conceptual model of financial path transition's decision making among entrepreneurs and study the impact of certain push-pull factors on the entrepreneurs' decisions.
Findings
The triangulated study identifies six categories of variables: financial freedom, workplace condition, independence, salary level, family life-building and retirement savings as key pull-push factors that significantly impact financial path transition's decision. Fuzzy cognitive mapping (FCM) extends our knowledge of the dynamics of CFQ transitions from a push-pull factor perspective. The results indicate no significant differences between the variables listed in the regression model and the fuzzy cognitive map model. Four categories of pull-push factors appeared as the entrepreneurs' top rankings when ordered by complexity, centrality scores and impact weight. These categories were workplace conditions, financial freedom, independence and salary level. The findings widen the scope of knowledge of each quadrant and rationalize how and why such factors impact quadrant decisions among Bahraini entrepreneurs.
Originality/value
Many studies discuss the CFQ model and consider its quadrants a specific method for identifying a unique financial path to generate income. A shifting quadrant occurs when individuals want to change their financial path and move beyond job security to achieve more financial freedom. Although this transition is well-established in the literature, the factors accounting for the individual's transition across quadrants have not received enough attention. This study fills this gap and calls for more in-depth investigations of this area to better understand the dynamics of CFQ transitions from a push-pull factor perspective.

Abstract
Travel time variability has generally been recognized as one of the most important attributes in travelers' route choice decisions. In fact, many empirical studies have indicated that both passengers and freight carriers are strongly averse to travel time variability, because it introduces uncertainty to their route choice decisions. In this chapter, we examine the effect of incorporating travel time variability and risk-taking behavior into the route choice models and its impact on the estimation of travel time reliability under demand and supply variations.

Abstract
Purpose
The purpose of this paper is to select a product suitable for printing via multi-axis additive manufacturing (MAAM), print it and test it to determine if, by using a multi-axis approach, it would be possible to create end use products that can withstand mechanical loading.
Design/methodology/approach
The methodology used in this study is a MAAM approach, and through the creation of an initial model and finite element analysis (FEA), the dominant stress vectors are identified. Using the orientation of these vectors, a three-dimensional tool path is constructed that follows the directionality as close as can be achieved while accounting for rotational road paths. This tool path is converted into a G-code and run on a 5-axis material extrusion printer. The printed samples were then tested according to the ISO standard to determine whether this can be a viable manufacturing technique.
Findings
The methodology used in this study enabled the production samples to withstand an average force of 1,100 N. This level is above the required safety threshold for the given standard. Furthermore, this reactive force is within 300 N of the typical metal sample, while being 25% of the typical weight for a conventional sample product. With a redesign and further research, it is possible to match the mechanical behaviour.
Originality/value
Recently, there has been an increased level of interest in MAAM. The research contained within this paper is original in its application of this printing method to explore whether it is possible to make end use products that meet the existing standards required by them.
