Abstract
Purpose
The purpose of this paper is to provide a review of the interdisciplinary research field, autonomous industrial mobile manipulation (AIMM), with an emphasis on physical implementations and applications.
Design/methodology/approach
Following an introduction to AIMM, this paper investigates the missing links and gaps between the research and developments efforts and the real‐world application requirements, in order to bring the AIMM technology from laboratories to manufacturing environments. The investigation is based on 12 general application requirements for robotics: sustainability, configuration, adaptation, autonomy, positioning, manipulation and grasping, robot‐robot interaction, human‐robot interaction, process quality, dependability, and physical properties.
Findings
The concise yet comprehensive review provides both researchers (academia) and practitioners (industry) with a quick and gentle overview of AIMM. Furthermore, the paper identifies key open issues and promising research directions to realize real‐world integration and maturation of the AIMM technology.
Originality/value
This paper reviews the interdisciplinary research field, autonomous industrial mobile manipulation (AIMM).

Abstract
Purpose
The purpose of this paper is to document and discuss the effects of a participatory intervention in preschools focussing upon improving the performance of the primary task on employee health and organizational effectiveness. Further, to investigate the role of implementation intensity on the outcomes.
Design/methodology/approach
A longitudinal, participatory intervention study of 62 preschools involving approximately 1,800 employees. The evaluation uses short-term sickness absence to measure employee health, employee-assessed primary-task quality and parent-assessed user satisfaction to measure organizational effectiveness, and implementation intensity was measured as hours per employee and as per the request by the workplace managers, and compensation was offered by the project.
Findings
The multi-level analyses show that preschools with higher implementation intensity have stronger effects on employee health and organizational effectiveness than preschools with lower implementation intensity. The differences indicate that the main intervention component, improving performance of the central work tasks through collaborative, participatory workplace activities, had effects on both health and effectiveness and that workplace and employee engagement in the intervention is crucial to its success.
Practical implications
Inspired by the Tavistock tradition for socio-technical systems design, the study indicates an avenue for conducting collaborative organizational change processes that benefit both employees and organizations. In addition, it proposes “hours used per employee” as a relatively simple measure of implementation intensity in such interventions.
Originality/value
The study contributes to research in the field of occupational psychological health by reporting on a comprehensive participatory intervention study comprising measures of employee health, organizational performance and implementation intensity.

Abstract
The author explores the variety of ways in which sports brands have risen to prominence and how the development of particular activities and relationships, with athletes, fans, media and regulators, are designed to present them as authentic. This status is crucial given the cultural and emotional significance of sport alongside its ability to underpin forms of collective belonging. A range of examples, including Red Bull, Nike, Patagonia, Olympic skateboarding and Manchester United Football Club, are used to highlight these processes as well as the complexity of the contemporary social, cultural and political landscapes that such brands now operate in.

Abstract
Purpose
People often engage in different information-seeking strategies (ISSs) within a single information-seeking episode. A critical concern for the design of information retrieval (IR) systems is how to provide support for these different behaviors in a manner which searchers can easily understand, navigate and use, as they move from one ISS to another. The purpose of this paper is to describe a dialogue structure that was implemented in an experimental IR system, in order to address this concern.
Design/methodology/approach
The authors conducted a user-centered experiment to evaluate the IR systems. Participants were asked to search for information on two different task types, with four different topics per task, in both the experimental system and a baseline system emulating state-of-the-art IR systems. The authors report here the results related explicitly to the use of the experimental system's dialogue structure.
Findings
For one of the task types, most participants followed the search steps as predicted in the dialogue structures, and those who did so completed the task in fewer moves. For the other task type, predicted order of moves was often not followed, but participants again used fewer moves when following the predicted order. Results demonstrate that the dialogue structures the authors designed indeed support effective human information behavior patterns in a variety of ways, and that searchers can effectively use a system which changes to support different ISSs.
Originality/value
This study shows that it is both possible and beneficial, to design an IR system which can support multiple ISSs, and that such a system can be understood and used successfully.

Abstract
Automatic classification of Web pages is an effective way to organise the vast amount of information and to assist in retrieving relevant information from the Internet. Although many automatic classification systems have been proposed, most of them ignore the conflict between the fixed number of categories and the growing number of Web pages being added into the systems. They also require searching through all existing categories to make any classification. This article proposes a dynamic and hierarchical classification system that is capable of adding new categories as required, organising the Web pages into a tree structure, and classifying Web pages by searching through only one path of the tree. The proposed single‐path search technique reduces the search complexity from θ(n) to θ(log(n)). Test results show that the system improves the accuracy of classification by 6 percent in comparison to related systems. The dynamic‐category expansion technique also achieves satisfying results for adding new categories into the system as required.

Abstract
This paper aims to replicate 148 anomalies and to examine whether the performance of the Korean market anomalies is statistically and economically significant. First, the authors observe that only 37.8% anomalies in the universe of the KOSPI and the KOSDAQ and value-weighted portfolios have t-statistics that exceed 1.96. When the authors impose a higher threshold (an absolute value of t-statistics of 2.78), only 27.7% of the 148 anomalies survive. Second, microcaps have large impacts. The results vary significantly depending on whether the sample included stocks in the KOSDAQ and whether value-weighted or equal-weighted portfolios are used. The results suggest that data mining explains large portion of abnormal returns. Any tactical asset allocation strategies based on market anomalies should be applied very cautiously.

Abstract
Purpose
As smart technologies become an integral part of real estate in smart cities, the purpose of this paper is to explore the impact of ubiquitous computing on space users in smart real estate.
Design/methodology/approach
The analysis builds on two fields of knowledge rarely referenced in real estate studies: computer sciences and social sciences. The paper starts by analysing the idiosyncrasies of a new type of space user in smart real estate, known as the Cyber-dasein in reference to Heidegger’s phenomenology. The Cyber-dasein serves as an archetypical space user in smart environments.
Findings
The paper introduces digital-time as a new realm of real estate, and discusses the use of “experienced utility” in hedonic pricing models of smart real estate. It concludes by advocating a multidisciplinary collaborative approach for future research on real estate in smart environments.
Practical implications
There is a need for the real estate sector to decide on a metric for the new digital dimension of real estate owing to the implementation of smart technologies in the built environment.
Originality/value
This is the first research paper on this important topic. It is totally original and new.

Abstract
Conflict resolution theory and practice have often neglected the contributions of women in peacebuilding. To obtain a more balanced perspective, the work of women's movements, peace movements, and other social movements have attempted to highlight the importance of women's roles in society and their active participation in peacemaking activities throughout the world. This study hopes to contribute to recognizing gender in conflict resolution by examining the rituals of conflict resolution in Laos and the legacy of women working for peace. Through this gender lens, it highlights the importance of Lao women's work in the soukhouan ceremony, a conflict resolution ritual that is integral to Lao culture. The soukhouan ritual demonstrates characteristics that are vital to any peacebuilding effort, specifically how women are actively working to repair harm, restore relationships, and organize support networks that are essential for reconciliation in communities experiencing conflict. This research adds to conflict resolution literature that validates how women are playing a vital role in all stages of peacebuilding.
