Fully-actuated unmanned aerial vehicles (UAVs) are a growing and promising field of research, which shows advantages for aerial physical interaction. The purpose of this paper is to construct a force sensor-denied control method for a fully-actuated hexarotor to conduct aerial interaction with accurate force exerted outward.

First, by extending single-dimension impedance model to the fully-actuated UAV model, an impedance controller is designed for compliant UAV pose/force control. Then, to estimate the interaction force between UAV end-effector and external environment accurately, combined with super-twisting theory, a nonlinear force observer is constructed. Finally, based on impedance controller and estimated force from observer, an interaction force regulation method is proposed.

The presented nonlinear observer-based impedance control approach is validated in both simulation and environments, in which the authors try to use a fully-actuated hexarotor to accomplish the task of aerial physical interaction finding that a specified force is able to be exerted to environment without any information from force sensors.

A solution of aerial physical interaction for UAV system enabling accurate force exerted outward without any force sensors is proposed in this paper.

This paper aims to propose and provide an overview of a model analysis that considers the main spatial design attributes that influence and produce the most relevant salutogenic outcomes. These results are essential for a healthy work experience, especially in shared workspaces.

This study departs from the theoretical contributions of the salutogenic approach, principles from supportive design theory, psychosocial supportive design and the environmental demands and resources model. After a scoping literature review covering different fields of workspace design, environmental psychology and evidence-based design of health-care facilities, a conceptual analysis is done on a proposed understanding of work, health and environmental relations to overview spatial attributes that enhance specific salutogenic and well-being-promoting outcomes needed for a healthy work experience.

The model of analysis, as a theoretical element that helps create methodological tools, combined with the application of a post occupancy evaluation, is thought to assist architects, designers, workspace owners and stakeholders in their new designs or to evaluate existing ones.

Studies on defining spatial attributes and their intended salutogenic outcomes have been formally done in health-care facilities. However, applying this idea to shared workspaces is something new and is expected to contribute to their design and evaluation, especially if the notion of environmental demands and resources is complemented.

Effectively engaging patients is critical for the sustainable development of online health communities (OHCs). Although physicians’ general knowledge-sharing, which is free to the public, represents essential resources of OHCs that have been shown to promote patient engagement, little is known about whether such knowledge-sharing can backfire when superfluous knowledge-sharing is perceived as overwhelming and anxiety-provoking. Thus, this study aims to gain a comprehensive understanding of the role of general knowledge-sharing in OHCs by exploring the spillover effects of the depth and breadth of general knowledge-sharing on patient engagement.

The research model is established based on a knowledge-based view and the literature on knowledge-sharing in OHCs. Then the authors test the research model and associated hypotheses with objective data from a leading OHC.

Although counterintuitive, the findings revealed an inverted U-shape relationship between general knowledge-sharing (depth and breadth of knowledge-sharing) and patient engagement that is positively associated with physicians’ number of patients. Specifically, the positive effects of depth and breadth of general knowledge-sharing increase and then decrease as the quantity of general knowledge-sharing grows. In addition, physicians’ offline and online professional status negatively moderated these curvilinear relationships.

This study further enriches the literature on knowledge-sharing and the operations of OHCs from a novel perspective while also offering significant specific implications for OHCs practitioners.

This chapter first describes the essential aspects of a currently changing world, which is characterised by digitalisation, globalisation and politically unstable situations. Based on this transformation context, key concepts such as leadership, innovation, innovation leadership and leadership competences are introduced, along with a new definition and framework for innovation leadership. The chapter discusses the distinction between innovation leadership and innovation management, and the connecting lines between these two concepts. The innovation leadership framework is described and related to the individual contributions of the authors in the book. The chapter frames these contributions along the dimensions of self-leadership, team leadership, organisational leadership and ecosystem leadership.

Soil quality is in decline in many parts of the world, in part due to the intensification of agricultural practices. Whilst economic instruments and regulations can help incentivise uptake of more sustainable soil management practices, they rarely motivate long-term behavior change when used alone. There has been increasing attention towards the complex social factors that affect uptake of sustainable soil management practices. To understand why some communities try these practices whilst others do not, we undertook a narrative review to understand how social capital influences adoption in developed nations. We found that the four components of social capital – trust, norms, connectedness and power – can all influence the decision of farmers to change their soil management. Specifically, information flows more effectively across trusted, diverse networks where social norms exist to encourage innovation. Uptake is more limited in homogenous, close-knit farming communities that do not have many links with non-farmers and where there is a strong social norm to adhere to the status quo. Power can enhance or inhibit uptake depending on its characteristics. Future research, policy and practice should consider whether a lack of social capital could hinder uptake of new practices and, if so, which aspects of social capital could be developed to increase adoption of sustainable soil management practices. Enabling diverse, collaborative groups (including farmers, advisers and government officials) to work constructively together could help build social capital, where they can co-define, -develop and -enact measures to sustainably manage soils.

Exploratory search activities are ubiquitous in various information systems. Much potentially useful or even serendipitous information is discovered during the exploratory search process. Given its irreplaceable role in information systems, exploratory search has attracted growing attention from the information system community. Since few studies have methodically reviewed current publications, researchers and practitioners are unable to take full advantage of existing achievements, which, in turn, limits their progress in this field. Through a literature review, this study aims to recapitulate important research topics of exploratory search in information systems, providing a research landscape of exploratory search.

Automatic and manual searches were performed on seven reputable databases to collect relevant literature published between January 2005 and July 2023. The literature pool contains 146 primary studies on exploratory search in information system research.

This study recapitulated five important topics of exploratory search, namely, conceptual frameworks, theoretical frameworks, influencing factors, design features and evaluation metrics. Moreover, this review revealed research gaps in current studies and proposed a knowledge framework and a research agenda for future studies.

This study has important implications for beginners to quickly get a snapshot of exploratory search studies, for researchers to re-align current research or discover new interesting issues, and for practitioners to design information systems that support exploratory search.

This systematic review (SR) aims to evaluate and summarize the effectiveness of using eye movement desensitization and reprocessing (EMDR) intervention among individuals diagnosed with post-traumatic stress disorder (PTSD), as well as to highlight the standardized EMDR-based interventional protocol.

This SR is guided according to preferred reporting items for SRs and meta-analyses standards. Several online databases were used in searching for eligible studies in peer-reviewed journals relevant to the study keywords. The included studies were SRs and clinical trials that used EMDR interventions among patients experiencing PTSD symptoms, older than 18 years and were published in English language from 2015 to 2022. Three researchers independently contributed to study selections, data extraction and study evaluations from different aspects, including quality assessment, risk of bias and study synthesis.

A total of eight published studies met the inclusion criteria and were included in this SR; four articles were randomized controlled trials and four were SR and meta-analysis studies. In all included studies, the EMDR was used as a primary psychotherapy intervention for PTSD symptoms. The results of this extensive and comprehensive review showed that EMDR is an effective psychotherapeutic intervention to reduce and control the severity of symptoms among individuals with PTSD.

It is important to acknowledge several limitations inherent in this study. First and foremost, it is noteworthy to mention that only studies conducted in the English language were included in this review, potentially restricting the overall scope and diversity of the findings. Furthermore, the number of studies incorporated into this review was limited, which may have implications for the comprehensiveness and generalizability of the results. Finally, it is worth noting that certain studies within this review had a relatively small sample size, which could potentially limit the statistical power and precision of the conclusions drawn.

This paper, a review of the literature, gives an overview of EMDR effectiveness, provides baseline information and plays a significant role in decreasing the gap in Jordanian literature regarding using EMDR as the strongest evident psychotherapy approach for PTSD treatment to help psychiatrists, psychologists and psychiatric nurses in the health-care sectors to design comprehensive strategies to enhance and improve the quality of health care and patients’ status.

EMDR intervention offers significant alternative treatment opportunities for individuals suffering from PTSD, depression and anxiety. The implementation of EMDR for depression, anxiety and PTSD improves patient outcomes as compared to standard therapeutic modalities in PTSD.

This SR gives an overview and explains strong supportive evidence for the effectiveness of EMDR interventions among individuals with PTSD. Therefore, EMDR therapy could be assumed as one standard treatment option for PTSD, aiming at reducing treatment duration and cost of treatment and restoring the mental well-being and functionality of those suffering from PTSD.

This study aims to investigate the impact of the audit committee chair’s trust on the quality of interactions between the external auditor and the audit committee chair in Hong Kong.

The research uses a questionnaire survey to gather data from the audit committee chairs of the listed companies in Hong Kong, with a response rate of 19.2%. Partial least squares structural equation modelling is used in this study.

The results reveal that the audit committee chair’s trust in the external auditor’s competence, integrity and goodwill is an important determinant of the interaction quality. The findings also show that interaction quality during the pre-engagement stage is important to mediate the relationships between the three dimensions of trust and interaction quality during the audit performance stage.

This is the first study, to the best of the author’s knowledge, that examines the impact of the audit committee chair’s trust in the external auditor on the quality of their interactions. The findings provide insights for board of directors, auditors and policymakers to implement policies that enhance trust between them to improve audit quality.

In the last two decades, risk reporting has followed a normative and calculative culture rather than the “materiality” of data. Although integrated reporting (IR) has become flooded with extra information, it does not adequately disseminate material information to stakeholders. In addition, the poor tone from the top diminishes creativity. This study aims to investigate how companies creatively address issues of the materiality of risk information in IR and how IR can be aligned with enterprise risk management.

Qualitative research was conducted via interviews with 50 chief risk officers and senior management executives in the Indian and UK insurance markets.

Overall, five institutions were observed to exhibit elements of being early adopters of institutional creativity. This confirmed the present study’s theoretical contribution of five divergent types of early adopters. The motivations for creativity are reflected in the resources available to these institutions.

To the best of the authors’ knowledge, this study provides a new insight into IR from internal mechanisms to deal with issue of materiality.
