Purpose
The stock market has shown fluctuating degrees of volatility because of the recent COVID-19 pandemic in India. The present research aims to investigate the effect of the COVID-19 on the stock market volatility, and whether the economic package can control the market volatility or not, measured by a set of certain sector-level economic features and factors such as resilience variables.
Design/methodology/approach
We examine the correlation matrix, basic volatility model and robustness tests to determine the sector-level economic features and macroeconomic factors helpful in diminishing the volatility rising because of the COVID-19.
Findings
The outcomes of this study are significant as policymakers and financial analysts can apply these economic factors to set policy replies to handle the unexpected fluctuation in the stock market in sequence to circumvent any thinkable future financial crisis.
Originality/value
The originality of the paper is to measure the variables affecting the stock market volatility due to COVID-19, and understand the impact of capital market macroeconomic variables and dummy variables to theoretically explain the COVID-19 impact on stock market volatility.

Purpose Lean management has been used in various constructions around the world for more than a quarter of a century, and it is an important factor in the construction of new projects. In relation to demolition management, only standards and codes and general principles of demolition of specific buildings were evaluated. The purpose of this study is providing relation between lean management on demolition processes of municipality buildings evaluated. Design/methodology/approach This study investigates the lean demolition of demolished and renovated buildings in a metropolitan area that can be extended to all cities. In the first stage, the effective factors in the demolition of the building based on lean management were identified through a valid questionnaire based on the valid Delphi approach. Social, economic and environmental considerations were considered in designing the appropriate questionnaire. Findings The modified approach between the fuzzy method and partial least squares was used to evaluate important variables. All of the modified processes were developed in MATLAB by the authors of this paper. The results show that customer-focused degradation parameter has the weakest effect and waste removal variable has the most effect on lean management. Originality/value Statistical results show that there is no significant difference between the effect of lean management on variables such as demolition time, quality and type of construction (p < 0.05).

Purpose The recent COVID-19 emergency has brought to light issues connected to physical work environment, particularly to offices and to its impact on service employees’ internal responses, behaviors and outcomes. As the topic is characterized by fragmented theoretical approaches as well as a lack in consolidated empirical research, this study aims at providing a clear understanding of the main – as well as the most recent – issues debated in academic literature today. Design/methodology/approach The study is a systematic literature review. Specifically, 124 papers, retrieved by Scopus, Web of Science and EBSCOhost research databases, are here systematically analyzed. Findings The main findings are connected to the prevalence of studies investigating employees’ satisfaction and productivity as main outcomes, the increasing attention by academics to new workplace designs, characterized by peculiar attributes such as flexibility and nonterritoriality, and finally, the lower interest in nonoffice working environments. Originality/value The review sheds light on the current knowledge of the relation between physical work environment and service employees to identify the main issues debated in academic literature and make suggestions for further research. First, the need to explore aspects of the physical work environment and employees’ outcomes that have not been adequately studied. Second, the relevance to investigate the above relation in public sector. Moreover, the importance of careful planning of the physical and virtual work environment in the context of the COVID-19 emergency.
目的最近的新冠肺炎紧急情况揭示了与物理工作环境有关的问题，特别是与办公室有关的问题及其对服务员工内部反应、行为和结果的影响。由于该主题的特点是理论方法零散，缺乏综合的实证研究，本研究旨在对当今学术文献中争论的主要问题以及最近的问题提供清晰的理解。设计/方法论/方法本研究是一项系统的文献综述。具体而言，本文系统分析了Scopus、Web of Science和EBSCOhost研究数据库检索到的124篇论文。发现主要发现与调查员工满意度和生产力作为主要结果的研究的普遍性有关，学术界越来越关注新的工作场所设计，其特点是灵活性和非属地性，最后是对非办公室工作环境的兴趣降低。原创性/价值这篇综述揭示了目前对物理工作环境与服务员工之间关系的认识，以确定学术文献中争论的主要问题，并为进一步研究提出建议。首先，需要探索尚未充分研究的物理工作环境和员工结果的各个方面。第二，研究公共部门中上述关系的相关性。此外，在新冠肺炎紧急情况下，仔细规划物理和虚拟工作环境的重要性。

Purpose This study aims to adapt analytical hierarchy process (AHP) for choosing the optimal location for sport facilities. The location of a sports facility contributes significantly to its potential success or failure. Therefore, factors affecting such location-related decisions must be carefully studied and prioritized in a systematic fashion. Design/methodology/approach This study develops a seven-step framework which may be used to decide on a location from among several alternatives. Through an extensive literature review, this study first determines the factors affecting sports facility location selection and then applies AHP steps by asking several sports facility owners and managers to assess importance of the criteria. Findings This study determined the sport facility location selection factors as “ease of access,” “facility features,” “financial issues,” “neighborhood” and “market,” and further divided each factor into its subfactors. To illustrate the framework of using AHP as a tool to select the right location for sport facilities, we chose three candidate locations and scored them according to the calculated weight scores of the criteria, identifying the strengths and weaknesses of each location. Practical implications This study provides several managerial implications that may guide sport facility investors in choosing the right location. Social implications This study presents a method to evaluate different factors for different actors of sport industry in a systematic way. Private investors can use the method for securing sufficient number of potential customers in a well-selected location. Government institutions and public policymakers can use the method, possibly with different sets of factors, to decide on the location of public sports facilities to maximize the number of visitors or to reach disadvantaged or underserved populations. Originality/value This framework of AHP method can help private and public investors and policymakers evaluate and make the optimal decision for choosing sports facility locations. This study contributes both to sport management theory and practice as well as to operation management literature. This study also refined the scattered factors in the literature of selecting a sport facility site in a more understandable and adaptable way.

Purpose The purpose of this article is to develop a bi-directional relaxed flexible bay structure (BRFBS) in the layout for the unequal area facility layout problems (UA-FLPs) and test the suitability of the proposed approach using literature data. Design/methodology/approach This research adopts a two-stage solution approach for UA-FLPs to form BRFBS in the layout. The solution to UA-FLPs is carried out in discrete space. The proposed heuristic method optimises the layout plan for minimising the material handling cost (MHC), and also, it indirectly optimises the space utilisation by reducing the empty space in the layout. The first stage of layout design assumes that all facilities are equal in size and uses quadratic assignment problem (QAP) model. QAP is solved with a simulated annealing heuristic method. In the second stage, a heuristic method is proposed to find the optimum width for each bay and the dimension for facilities. The proposed heuristic method is tested with numerical data available in the literature. Results are compared with the results obtained by layout planning software, and with the simulated annealing algorithm for flexible bay structure (SA-FBS) heuristic procedure for continuous space UA-FLPs. Findings The proposed two-stage solution approach gives the BRFBS for the UA-FLPs. BRFBS helps to create proper aisle structure in the layout plan. The layout configuration and solution of the proposed method is better than the layout planning software solution and SA-FBS solution. The application of the proposed heuristic method to case data gave lesser MHC, better space utilisation and better aisle formation than the existing layout. Research limitations/implications The proposed approach has the limitation that it can be applied only to UA-FLPs solved in discrete space. When the UA-FLPs are solved in continuous space, then it is not possible to make application of this approach to form bi-directional relaxed flexible bays in the layout plan. Practical implications Most of the modern industries are automated, and they use material handling equipment (MHE) like automated guided vehicles (AGVs). Design of layout plans that help to create proper aisle structure for AGV’s in the layout plan is a challenging to the researchers. The BRFBS configuration is more suitable in the flexible manufacturing system where AGVs are used for material transportation. Originality/value This paper proposes a novel two-stage heuristic method for solving the UA-FLPs in discrete space. The proposed approach generates a BRFBS in the layout plan. The BRFBS helps to create a proper aisle structure suitable for better material handling operations. Hence, this type of layout helps in easy interaction of the MHE (e.g. AGVs) with the boundaries of the facilities touching the aisle.

Purpose As far as the authors know, no research has already been carried out on the multi-floor dynamic facility layout problem (MF-DFLP) in the continuous form regarding the flexible bay structure, the number and the variable location of the elevator. Therefore, the present paper models the given problem and attempts to find a sub-optimal solution for it using a meta-heuristic simulated annealing (SA) algorithm. Design/methodology/approach The efficient use of resources has always been a prominent matter for decision-makers. Many reasons including land use, construction considerations and proximity of departments have led to the design of multi-floor facilities. On the other hand, their fast-evolving environment calls for dynamic planning. Therefore, in this paper, a model and the SA algorithm for MF-DFLP are presented. Findings After presenting a mathematical model, the problem was solved precisely in a small size using the GAMS software. Also, a near-optimal solution method using a SA meta-heuristic algorithm is suggested and the proposed algorithm was run in the MATLAB software. To evaluate the presented model and the proposed solution, some test cases were considered in two aspects. The first aspect was the test cases that are newly generated in small, medium and large sizes to compare the exact optimal solution with the results of the meta-heuristic algorithm. Eight test cases with small sizes were solved using the GAMS software, the optimum solutions were obtained in a reasonable time, and the cost of their solutions was equal to that of the SA algorithm. Eight test cases with medium sizes were run in the GAMS software with the time limit of 80,000 s, and the SA algorithm had performed better for these test cases. Two test cases were also considered in large size that GAMS could not solve them, whereas the SA algorithm successfully found a proper solution for each. The second aspect included the test cases from the literature. The result showed that suggested algorithm is more capable of finding best solutions than compared algorithms. Originality/value In this paper, an unequal area MF-DFLP was studied in a continuous layout form in which the location and number of the elevators were considered to be variable, and the layouts were considered with flexible bay structure. These conditions were investigated for the first time.

Purpose This study aims to examine the key components to facilitate flexible work arrangement (FWA) and the issues and challenges arisen in preparing the workplace for FWA during Covid-19, and to recommend better approach of FWA implementation in workplace. Design/methodology/approach This study adopted extensive literature review and case studies approach using interviews and observations to determine the key components to facilitate FWA and the issues and challenges arisen in preparing the workplace for FWA during Covid-19, and to recommend better approach of FWA implementation in workplace. Three offices that owning FWA experience during Covid-19 and featuring flexible workspace concepts, elements and layouts in Klang Valley, Malaysia were chosen as case studies. Findings Findings have suggested that there are four components required to form flexible workspace for FWA adoption, such as open plan workspace design, task-oriented space, hot desking policy and IT infrastructure. Interestingly, the interview findings do not support the idea that the flexible furniture can facilitate FWA; instead, they believe that versatile, acoustical and aesthetical furniture may be installed when necessary. Among the issues and challenges faced were rearranging and designing open office plan layout, hot desk relocation and reconfiguration of spaces where people may congregate. Lastly, this research recommends that innovative planning software and tools, smart technology and apps, modern IT technology and infrastructure, and digital apps can be introduced to the workplace to help FM manage and monitor the facilities operations, workplace situations and occupancy rates. Originality/value Since the outbreak of Covid-19, FWA such as “Work From Home” and remote working have become the mainstream in the workplace, affecting how the workplace looks and feels as flexible working is fundamentally related to the flexible workspace. From Facilities Management (FM) perspective, FWA is the biggest consequence of Covid-19, but it also presents opportunities and certain challenges to incorporate a new office environment and employees’ needs in terms of FWA into the corporate culture.

Purpose Among the existing buildings, hotels use as much as 50% of their total expenses on energy and offer significant opportunities for energy efficiency improvement. Yet, comparatively the level of implementation of energy retrofits (ER) in hotels appear to be low. This has been mainly attributed, inter alia, to the absence of clearly defined process for ensuring the delivery of ER and lack of proactive guidance for project teams to make right decisions. Hence, this study aims to propose an effective decision-making process, which could support the successful adoption and implementation of in-house-led ER projects in existing hotel buildings. Design/methodology/approach Two in-depth case studies were carried out focussing on ER projects led by in-house teams in existing hotel buildings. Data was collected via 14 semi-structured interviews and was analysed through code-based content analysis. Findings The decision-making process for ER projects led by in-house teams was developed, which presents 39 key activities to be performed and 16 key decisions to be made. The parties responsible for these identified actions and decisions as well as the points at which each decision should be made to ensure the success of ER projects was also identified. Originality/value A total of 21 new activities and 10 decisions relevant for in-house team led ER decision-making processes previously not found in literature were identified. It is hoped that the decision-making process developed in this study will serve as a roadmap for the effective adoption and implementation of ER in existing hotel buildings.

Purpose Business-to-government corruption has destroyed many businesses and debilitated numerous countries. The paradox of plenty, or the curse of resources, is exacerbated in emerging oil and gas economies, where corruption is rampant. Corruption most frequently occurs within the tendering stage of construction projects and the current debate fails to arrest this ubiquitous boundless construct in small island developing states (SIDSs). The purpose of this study is to explain how the unique features of SIDS contributes to an understanding of B2G corruption during construction tendering. Design/methodology/approach This study elucidates corruption in the tendering process through the lens of collective action and principal–agent theories. Interviews with three experts and a questionnaire survey with 115 practitioners evaluated corruption in Trinidad’s construction industry. Principal component analysis reduced 33 corruption variables to 5 primary causes. In addition, the relative importance of potential solutions for curtailing corruption was assessed. Findings The derived factors highlight that governance within SID oil and gas economies, inadequate tender procedures and practices, reprehensible business growth strategies, unethical misconduct and the social networking context characterise public infrastructure tendering. The recommendations for minimising corruption in tendering are grounded in behaviour and deterrence theories and infused with technological advances. Research limitations/implications Using surveys and interviews circumvents the limitation of the inability to measure corruption because of the confines of respondents’ recall triggers. However, corruption is mediated by cultural norms, which limits the generalisation of the findings. Originality/value The study concludes that corruption results from a lack of transparency in the construction supply chain. It leads to an awareness gap between project stakeholders, which is a major risk factor and source of mistrust. The result is a lack of traceable processes and coordination among stakeholders. Consequently, the study fills the gap in responsible socio-economic consumption in SIDSs.
