The purpose of this paper is to develop an operational framework with guidelines and lessons to improve the current real estate portfolio disposal procedures of freeholds, based on empirical evidence from the banking sector.

The empirical research is based on a comparative analysis of four case studies, representing approximately 80 per cent of the Dutch banking sector. The case studies comprise a systematic document review of corporate business and real estate strategies and semi-structured interviews with decision makers who steer the organisation’s corporate real estate (CRE) portfolio composition.

This research shows a strong relationship between organisation characteristics, legacy and strategy, disposal drivers and CRE disposal strategies. The weighing of drivers and order of steps in strategy execution strategies largely depend on organisational objectives.

This paper reports empirical findings from Dutch case studies. To generalise, further research is needed in different legal, financial and economic contexts and in other sectors. This paper suggests a more thorough study of the relationship between space-use efficiency and technological innovation implementation..

The framework proposes strategy improvements and a proactive approach to corporate real estate management (CREM) to create value through real estate portfolios.

This paper provides a thorough analysis of the CREM of the Dutch banking sector and is applicable to CREM in this and other sectors.

This paper's aim is to assess the practical advances resulting from progress in artificial intelligence affecting vision‐equipped robots.

A short history of artificial intelligence applied to robotic hand‐eye coordination is followed by a description of some of the milestones in pattern recognition, interfacing, operating systems and programming paradigms. Finally, a range of current‐day practical applications is given, from industrial to student project.

The paper finds that advances in the speed and robustness of pattern recognition algorithms have been very important in the development of robots that adapt to randomly positioned workpieces. Event‐triggered object oriented programming, wide address buses, smart cameras, ethernet and other standard cables and communications formats, and the ever‐increasing power of computers are also of great practical importance.

The paper contrasts the current state of robotic vision with that 20 years ago.

This paper aims to propose a novel wheel-based multiaxis force sensor designed to detect the interaction forces and moments between the planetary rover’s wheel and the terrain, thereby assisting the rover in environmental perception.

The authors’ design approach encompasses the mechanical structure design, decoupling methods and component integration techniques, effectively incorporating multiaxis sensors into the forward-sensing wheel. This enables high-precision and high-reliability detection of wheel–terrain interaction forces and torques.

The designed wheel-based multiaxis force sensor exhibits a nonlinearity error of 0.45%, a hysteresis error of 0.56% and a repeatability error of 0.49%, meeting the requirements for practical applications. Furthermore, the effectiveness and stability of the designed wheel-based multidimensional force sensor have been validated through hardware-in-the-loop experiments and full-vehicle model testing.

Unlike previous methods that directly integrate multiaxis sensors into the forward-sensing wheel, the authors have designed the force sensing wheel with consideration of its limited design space and the need for high measurement accuracy. The effectiveness of the designed wheel-based multidimensional force sensor was ultimately validated through static calibration, hardware-in-the-loop experiments and full-vehicle model experiments.

The purpose of this paper is to investigate how to make tele‐operated tasks easier using an expert system to interpret joystick and sensor data.

Current tele‐operated systems tend to rely heavily on visual feedback and experienced operators. Simple expert systems improve the interaction between an operator and a tele‐operated mobile‐robot using ultrasonic sensors. Systems identify potentially hazardous situations and recommend safe courses of action. Because pairs of tests and results took place, it was possible to use a paired‐samples statistical test.

Results are presented from a series of timed tasks completed by tele‐operators using a joystick to control a mobile‐robot via an umbilical cable. Tele‐operators completed tests both with and without sensors and with and without the new expert system and using a recently published system to compare results. The t‐test was used to compare the means of the samples in the results.

Time taken to complete a tele‐operated task with a mobile‐robot partly depends on how a human operator interacts with the mobile‐robot. Information about the environment was restricted and more effective control of the mobile‐robot could have been achieved if more information about the environment had been available, especially in tight spaces. With more information available for analysis, the central processor could have had tighter control of robot movements. Simple joysticks were used for the test and they could be replaced by more complicated haptic devices. Finally, each individual set of tests was not necessarily statistically significant so that caution was required before generalising the results.

The new systems described here consistently performed tasks more quickly than simple tele‐operated systems with or without sensors to assist. The paper also suggests that the amount of sensor support should be varied depending on circumstances. The paired samples test was used because people (tele‐operators) were inherently variable. Pairing removed much of that random variability. When results were analysed using a paired‐samples statistical test then results were statistically significant. The new systems described in this paper were significantly better at p<0.05 (95 per cent probability that this result would not occur by chance alone).

The paper shows that the new system performed every test faster on average than a recently published system used to compare the results.

Effective literature searches are critical to researchers and health care professionals. To conduct literature searches, clinicians, researchers and nurses rely primarily on a few major databases (PubMed, Cochrane, CINAHL, etc.) to retrieve information. However, there is a lack of literature on the comparative efficiencies of major databases for systematic review results on a clinically related topic. This paper aims to fill that gap in the literature.

Cochrane Handbook (2011) defines systematic review as a review of a clearly formulated question that uses systematic and explicit methods to identify, select and critically appraise relevant research and to collect and analyze data from the studies that are included in the review. In this paper, search results of systematic reviews on a clinical topic between two major databases – PubMed and Cochrane Library – are compared.

Searching within PubMed for key terms in the titles and abstracts of articles is important to include in any systematic review, in addition to searching Medical Subject Heading terms. After applying filters, PubMed retrieved 130 systematic reviews that matched the criteria. In Cochrane Library, the searches were performed on the chosen topic using Boolean and phrase searching: text field searches resulted in 251 reviews. The search was further narrowed by subject, which yielded 20 reviews. It is strongly recommended to use multiple health-care specialty databases, check for duplicate reviews in the results and not limit results to English-only publications.

This paper can be used to introduce new researchers and/or students to methods for conducting systematic reviews using two or more databases on a chosen topic.

This paper fills a gap in the literature regarding comparative efficiencies of major databases for systematic review results on clinically related topics.

Purpose – The present chapter discusses how qualitative research can assist in rethinking and transcending the limitations of the notion of one-way knowledge transfer, which is still a dominant ontological paradigm of organizational learning in China.

Approach – The authors first present their critiques of the dominant knowledge transfer research paradigm. Then, using a recent case example, they illustrate how qualitative research, coupled with the alternative ontological paradigm of knowledge translation can provide context-sensitive insights into how cultural barriers and other knowledge boundaries can be crossed and how breakthroughs in knowledge transfer can be achieved.

Findings – Qualitative methods are highly appropriate for understanding complex social processes involving political and cross-cultural dynamics. They are ideal for gathering and making sense of the various perceptions, feelings, assumptions, aspirations, motives, and attributions that are held by members of different groups. They can track the sequence of key events and critical choices, and they can provide insights into the anatomy of social networks and power structures.

Originality/Value – The present chapter highlights the areas where qualitative designs can generate novel and fascinating insights regarding organizational learning in China. The authors argue that if researchers are interested in the diversity of conditions, in knowledge creation, and in the emergence of new practices within unique contexts, then they would be well advised to adopt qualitative designs.

Much of the existing commercial building stock in Western Australia has the ability to adapt to varying conditions such as climate change, which provides some potential for reusability and sustainability. Current sustainability assessment systems tend to be relevant only for new construction. The purpose of this paper is to examine the use of the National Australian Built Environment Rating System (NABERS) to address this gap by considering the influence of occupant behaviour on performance.

Feedback provided from 39 stakeholders during a public review of NABERS and a subsequent trial of NABERS on nine office buildings in Sydney and Victoria are examined. The data are obtained from the Department of Environment and Heritage and NSW Department of Energy, Utilities and Sustainability (now the Department of Environment and Climate Change).

Assessment of the environment performance of existing facilities is needed to improve their energy efficiency. These findings need to be given serious thought when considering an adaptation strategy or the construction of a new facility. From a sustainability perspective, it will almost always be a more viable option to use an adaptive re‐use strategy. The use of adaptation will require clients and designers to re‐examine how their facilities are to be used and require them to embrace whole‐life costing and the use of innovative materials and technologies.

Adaptive re‐use has received limited attention in Australia, as there has been a tendency to demolish or construct new buildings in response to client demands. However, adaptation is proving to be an effective strategy in ensuring a sustainable built environment. This research provides the impetus and foundations for exploring the invaluable role of adaptation and energy efficiency of existing facilities.

The purpose of this paper is to study the path optimization method of the manipulator in the lunar soil excavation and sampling process. The current research is a practical need for the excavation and sampling of the lunar soil in the lunar exploration project.

This paper proposes the objective function and constraints for path optimization during the excavation process of the lunar soil, regarding excavation time and energy consumption as the two key fitness indexes by analyzing the whole excavation process of the lunar soil. Specifically, the optimization is divided into two consecutive phases, one for the excavation path and the other one for joint motions. In the first phase, the Bézier polynomial is adopted to get the optimal excavation angle and reduce energy consumption. In the second phase, a method based on convex optimization, variable conversion and dynamic process discretization, is used to reduce excavation time and energy consumption.

Controlled experiments on the fine sand and the simulant lunar soil were conducted to verify the feasibility and effectiveness of the two phases of the optimization method, respectively.

The optimization method of the excavation tasks in this paper is of great value in theoretical and practical engineering, and it can be applied in other robotic operational tasks as well.

The study aims to investigate the relationship between certain key attributes of the board of directors as their international experience, tenure, age, independence and size and internationalization strategies of firms in an emerging economy.

The study uses random effects panel Tobit regression on a data set of 418 Indian companies spanning over a time frame of nine years from fiscal year (F.Y.) 2009–2010 to F.Y. 2017–2018.

Board members substantially associate with internationalization choices of emerging economy firms. Specifically, board members with extensive international experience, shorter tenure, higher age, greater independence and larger board size are associated with high level of internationalization in these firms.

The study advocates that Indian companies should focus on recruiting board members with international experience, periodically refreshing their boards, valuing wisdom and experience, adhering to regulatory requirements of independent directors and increase the number of board members to expand internationally. By following this, Indian companies can successfully expand into international markets.

The study’s originality lies in its focus on the role of board members in the internationalization strategy of emerging economy firms, which remains an under-researched area.
