Stakeholder Perspective

Purpose This paper aims to identify the state of the art in Green Leases and Green Leasing in theory and practice, while also identifying how the roles and motivations of the stakeholders of “owner/landlord”, “lessee” and “facilities management” are different in a building that uses Green Leasing and Green Leases, as opposed to the one without. Design/methodology/approach Through existing literature and existing case studies from 1995 to the present day, this paper will identify the state of the art of Green Leases and Green Leasing and the extent to which literature-based discussions have played out in their practical application in the real estate sector. The roles of key stakeholders will be analysed and then compared to the interactions and roles identified in a theoretical model that describes the same stakeholders but from a more traditional stakeholder perspective. This will be achieved through using literature from journal papers mostly from the disciplines of built environment, facilities management, finance, investment, law, management and real estate. Findings The literature and case studies found in literature demonstrate a gradual move towards advancing Green Lease adoption and development. While the roles of key stakeholders do see a change in Green Leased buildings in terms of, for example, changing competencies for facilities managers (FMs) and more user engagement with their buildings sustainability, the literature indicated most of the changes are realised through a strengthening of existing interactions already evident in buildings without a Green Lease or Green Leasing. Originality/value This paper provides a state of the art review on the development of Green Leasing and Green Leases in theory and practice from a stakeholder perspective. It provides possibility to expand further on the changing roles of these stakeholders in Green buildings, which in turn could also positively affect the further development of Green Leases themselves, as well as sustainable certification methodologies such as Europe’s leading certification “Building Research Establishment Environmental Assessment Method” (BREEAM).

State Of Research

Purpose This paper aims to review the state of the art for the Tourism Review special issue on “Business Models in Tourism”. The authors’ purpose is twofold: first, to contextualize the empirical and conceptual contributions featured in the special issue in relation to the state of research on business models in tourism. Second, the authors position the special issue in the broader scholarly conversation on business models to identify avenues for future research. Design/methodology/approach The authors systematically review the content of tourism-specific business model studies from leading literature databases to answer four questions relevant for future work on business models in tourism: First, how do tourism scholars define the business model concept? Second, what is the ontological stance (object, schema or tool) of existing studies of tourism business models? Third, what are the methodological preferences of existing work on business models in tourism? And finally, what qualifies as rigorous business model research? Findings From the critical review of 32 contributions, the authors identify a minimal consensus and dominant approach to conceptualizing the business model concept in tourism studies. In addition, the authors reveal a strong preference for small-n case study research designs. In sum, those findings point to important gaps and design decisions for future business model studies in tourism. Originality/value This review of the state of research on business models in tourism details research opportunities with regard to theory, methods and applications that tourism scholars can investigate to contribute to the theory and practice of business model management.

PurposeFocussing on the UK’s institutional real estate universe, this paper analyses variations in the operational management of real estate investment portfolios. For the main categories of institutional investors, the key tasks in real estate operational management, and the ways in which these tasks are typically bundled and categorised by investment managers are reviewed. Three broad operational management models are outlined. Case studies of real estate operational management models in practice are discussed.Design/methodology/approachThe research approach is primarily descriptive, drawing upon illustrative investor case studies.FindingsA range of operating models are identified for managing real estate investment portfolios. Specialists real estate investors tend to have highly vertically integrated operating models viewing most operational management functions as core operational capabilities. Multi-asset owners tend to have a vertically disintegrated operating model outsourcing fund, asset, property and facilities management. Investing institutions such as fund houses and specialist real estate investment advisors seem to have converged upon a common hybrid operating model with high margin, analytical functions such as fund and asset management being insourced and low margin, routine functions such as property and facilities management being outsourced.Originality/valueDespite the size of the global, institutional real estate investment universe (estimated by DTZ to be worth more than USD 13.6 trillion in 2015), the topic of how (and how effectively) these assets are managed by institutional investors has attracted very little attention from the real estate research community. This paper provides some initial analysis and insights into operational management models for real estate investment portfolios in the contemporary real estate investment management landscape.

Purpose This paper aims to evaluate four different simultaneous localization and mapping (SLAM) systems in the context of localization of multi-legged walking robots equipped with compact RGB-D sensors. This paper identifies problems related to in-motion data acquisition in a legged robot and evaluates the particular building blocks and concepts applied in contemporary SLAM systems against these problems. The SLAM systems are evaluated on two independent experimental set-ups, applying a well-established methodology and performance metrics. Design/methodology/approach Four feature-based SLAM architectures are evaluated with respect to their suitability for localization of multi-legged walking robots. The evaluation methodology is based on the computation of the absolute trajectory error (ATE) and relative pose error (RPE), which are performance metrics well-established in the robotics community. Four sequences of RGB-D frames acquired in two independent experiments using two different six-legged walking robots are used in the evaluation process. Findings The experiments revealed that the predominant problem characteristics of the legged robots as platforms for SLAM are the abrupt and unpredictable sensor motions, as well as oscillations and vibrations, which corrupt the images captured in-motion. The tested adaptive gait allowed the evaluated SLAM systems to reconstruct proper trajectories. The bundle adjustment-based SLAM systems produced best results, thanks to the use of a map, which enables to establish a large number of constraints for the estimated trajectory. Research limitations/implications The evaluation was performed using indoor mockups of terrain. Experiments in more natural and challenging environments are envisioned as part of future research. Practical implications The lack of accurate self-localization methods is considered as one of the most important limitations of walking robots. Thus, the evaluation of the state-of-the-art SLAM methods on legged platforms may be useful for all researchers working on walking robots’ autonomy and their use in various applications, such as search, security, agriculture and mining. Originality/value The main contribution lies in the integration of the state-of-the-art SLAM methods on walking robots and their thorough experimental evaluation using a well-established methodology. Moreover, a SLAM system designed especially for RGB-D sensors and real-world applications is presented in details.

Pruning Techniques

PurposeEnsemble methods have been widely used in the field of pattern recognition due to the difficulty of finding a single classifier that performs well on a wide variety of problems. Despite the effectiveness of these techniques, studies have shown that ensemble methods generate a large number of hypotheses and that contain redundant classifiers in most cases. Several works proposed in the state of the art attempt to reduce all hypotheses without affecting performance.Design/methodology/approachIn this work, the authors are proposing a pruning method that takes into consideration the correlation between classifiers/classes and each classifier with the rest of the set. The authors have used the random forest algorithm as trees-based ensemble classifiers and the pruning was made by a technique inspired by the CFS (correlation feature selection) algorithm.FindingsThe proposed method CES (correlation-based Ensemble Selection) was evaluated on ten datasets from the UCI machine learning repository, and the performances were compared to six ensemble pruning techniques. The results showed that our proposed pruning method selects a small ensemble in a smaller amount of time while improving classification rates compared to the state-of-the-art methods.Originality/valueCES is a new ordering-based method that uses the CFS algorithm. CES selects, in a short time, a small sub-ensemble that outperforms results obtained from the whole forest and the other state-of-the-art techniques used in this study.

Structured Literature Review

Purpose – The application of business process methods in the domain of disaster response management (DRM) is seen as promising approach due to the similarity of business processes and disaster response processes at the general structure and goals. But up to now only a few approaches were able to handle the special characteristics of the DRM domain. Thus, the purpose of this paper is to identify the existing approaches and analyze them for the discussion of general requirements for applying methods and tools from business process management to DRM. Design/methodology/approach – A structured literature review covering a wide field of information system-related publications (conferences and journals) is used to identify and classify general requirements discussed as the state of the art. Findings – The work in this paper resulted in a suitable classification of requirements for the development of process-oriented DRM approaches deduced from the existing work. This was used to outline and analyze the current research landscape of this topic and identify research gaps as well as existing limitations. Research limitations/implications – Although the review of the state of the art is based on a wide set of publication databases, there may exist relevant research papers which have not been taken into consideration. Originality/value – The elaborated requirements provide value for both the research community and practitioners. They can be considered to develop new or improve existing DRM systems and, thus, to exploit the potentials of process-oriented IT in supporting DRM in the case of disaster.

PurposeThe purpose of the paper is to discuss the scope for improving the delivery of FM services through the use of wireless web‐based communications infrastructure, delivered via an application service provider (ASP) business model. This paper discusses the findings from case studies of three organisations and their approach to the management of facilities.Design/methodology/approachAn investigation was undertaken to ascertain the current state of play in terms of managing and tracking processes within the facilities management department of three different organisations. These case studies were chosen from distinct sectors, namely health care, higher education, and banking. Emphasis is placed on analysing how the organisations currently operate with their existing FM systems and the degree of influence technology has on existing processes. This was considered mainly in terms of computer‐aided facilities management (CAFM) and computer‐integrated facilities management (CIFM).FindingsThe study found that a new wireless web‐based service for FM systems would be considered useful. Although notoriously slow adopters of new technology, there was an acceptance by the facilities managers interviewed that a wireless web‐based approach would improve current practice, especially with respect to real‐time job reporting and tracking and in the determination of FM operative working time utilisation.Practical implicationsFurther work by the author is focusing on the development of a suitable demonstrator to illustrate the key concepts of a wireless web‐based FM service which will then be tested and evaluated. For further information, visit the research project web site at www.wirelessfm.org Originality/value – The paper hopefully stimulates discussion in the area of emerging wireless technologies that have the potential to streamline and improve current practices for the management of facilities, in particular that of real‐time job reporting and tracking.

Abstract The purpose of this article is to highlight the state of the art of virtual reality, augmented reality, mixed reality technologies and their applications in formal education. We also present a selected list of case studies that prove the utility of these technologies in the context of formal education. Furthermore, as byproduct, the mentioned case studies show also that, although the industry is able to develop very advanced virtual environment technologies, their pedagogical implications are strongly related to a well-designed theoretical framework.

Before And After

Purpose – The purpose of this paper is to evaluate the effectiveness of this legislative reform in the state of South Australia (SA) through an examination of the relationship between listed or advertised price and transaction prices before and after the changes in regulation. Between 2000 and 2008, legislative changes took place throughout Australia to make real-estate transactions more transparent and to deal with misleading conduct by real-estate agents. The practice of “charm” or “bait” pricing was targeted. This denotes the under-quoting of estimated selling prices in real-estate sale advertisements which can be considered deceptive or even fraudulent. Design/methodology/approach – The study area is Adelaide, the state capital of SA and includes analysis of first and last advertised prices and eventual selling price for > 120,000 residential sales transactions over a nine-year period between 2003 and 2011. The analysis to test these hypotheses included, first, a descriptive evaluation of the percentage price difference over time and a spatial breakdown of mean percentage price difference before and after legislation. Second, for each hypothesis, the change was tested by measuring the variance of the percentage change, with significance established through the Levene and Brown–Forsythe tests, rather than by the mean percentage change. Findings – The results, both descriptive and statistical, support the effectiveness of the reform in legislation. Research limitations/implications – The study has application in terms of agents as social gatekeepers and confirms the role of regulation to ensure market values are achieved and consumers not disadvantaged. With friction in the market, imperfect information and the possible behavioural responses of land agents, there may be incomplete market correction of underpricing strategies. This paper confirms the effectiveness of one such market intervention. Social implications – Some half a million dwellings are purchased in Australia every year. Annually, in the state of SA, some 53,000 dwellings are financed to be purchased or built. These levels of purchase reflect national home ownership rates of about 69 per cent, with some 33 per cent of Australians owning their houses outright and a growing number, some 36 per cent, owners with a mortgage. Australian households also move house relatively frequently. In 2008, 43 per cent of Australians reported moving in the previous 5 years, 15 per cent had moved 3 or more times. The most common reasons for moving were twofold, either to buy a house or to buy a bigger house. These levels of purchase, home ownership and mobility underpin the importance and viability of some 10,000 real-estate services businesses in Australia; a sector which, up to 2,000, was largely self-regulated. Originality/value – This paper is one of the first in Australia to effectively quantify the success of legislative reform on residential agency behaviour.
