Abstract

Purpose

The purpose of this paper is to identify safety hazards likely to be encountered during post‐disaster recovery and reconstruction, identify barriers to effective safety training and hazard mitigation, and provide actionable guidance on methods to safely avoid and abate such hazards.

Design/methodology/approach

Surveys were administered to 400 participants at 13 training sites to evaluate safety practices among reconstruction contractors and workers.

Findings

A comparison of survey results to hazards likely to cause injuries and fatalities during post‐disaster reconstruction indicates that little effort is made to assess workers' physical condition or immunization records prior to deployment. Furthermore, data suggest that workers lack safety training in reconstruction‐specific hazards such as electrocution, falls, chemical and biological hazards (e.g. contaminated flood water), and equipment hazards (aerial lifts, ladders, electric equipment, generators, etc.). Findings also indicate that training effectiveness is further compromised by limited language and literacy skills of workers, high turnover of workers, and insufficient resources for adequate safety training frequency and duration, especially among smaller contractors (<100 workers).

Originality/value

The paper is based on original research funded by the US Government following Hurricane Katrina and is intended to aid in the development of targeted training to reduce worker injuries and fatalities during post‐disaster reconstruction.

Abstract

Purpose

Although the threat of terrorist attacks is not a new phenomenon for hotels, limited literature exists on measures that hotels can take to prevent them or limit their damage. The purpose of this paper is to propose a baseline strategy to address this threat.

Design/methodology/approach

Using the terrorist attack cycle and the security function models introduced in this paper, 19 hotel security experts, members of an international working group on terrorism, were tasked to reach consensus on a baseline anti‐terrorist strategy for a hotel. To reach this consensus, the study employed the Nominal Group Technique.

Findings

The study presents a six‐step baseline anti‐terrorism strategy and a series of measures and actions under each step. In the centre of this strategy lies the disruption of the terrorist attack cycle.

Research limitations/implications

There are limitations inherent to the Nominal Group Technique which may not allow the generalizability of the findings. However, every effort was made to ensure the reliability and validity of the study.

Practical implications

The study suggests a shift from physical protection alone to a more intelligence‐led approach. Counter‐surveillance, terrorist behavioral analysis, higher visibility of security measures, stronger relationships with local community leaders, collaborative relationships with emergency response agencies and strategic use of risk intelligence providers will have to take a higher place in the agendas of hotel security departments.

Originality/value

The paper presents, for the first time, two models that industry practitioners will find useful when designing security policies: the terrorist attack cycle and the security function model. Each component of the proposed strategy provides a starting point for the design of security strategies tailored on the security needs and budget of any hotel property.

Abstract

Purpose

This paper aims to explain the current state of energy consumption and economic development in Beijing's construction industry and identify the relationship between the two systems so as to supply decision support for the future.

Design/methodology/approach

This paper presents a design of a coordinated development model based on the theory of synergetics. The focus of the paper is on how to integrate energy consumption indices and economic development indices to determine coordinated development indices in a relevant and useful manner. While analyzing energy composite consumption and economic composite development, respectively, all the variables normalized are eliminated inter‐correlated characteristics by making use of principal component analysis (PCA).

Findings

Beijing's construction development is experiencing the transition from economic development hysteresis to energy consumption hysteresis. The higher coordinated development degree is predicting the energy‐economy system is trending to stability in Beijing's construction industry which does not necessarily mean a perfect development trend but an upper limit of the increasing rate in energy consumption. Thus, or at least maintaining the current economic development and energy utilization policy, production specifications, or using new technology, new method and economic policy to stimulate the economic development, or more attention from all the stakeholders being paid to saving more energy than before, will be still priority considerations for Beijing's construction industry in the following years.

Originality/value

The paper proposes an original framework for examining the relationship between energy consumption and economic development in construction industry. The framework is also capable of identifying if the growth rate in energy consumption goes beyond the upper limit.

Abstract

Purpose

Trade credit is treated as a financial intermediation device whereby construction vendors act as financial providers to their customers through deferred payments of goods purchased. The purpose of this paper is to investigate and report upon the key factors and motives influencing vendors' decision on trade credit provision to small to medium sized construction firms.

Design/methodology/approach

Adopting deductive methodological approach, this paper utilises a combination of primary data emanating from structured survey questionnaires supplemented by secondary source of data from an extensive literature review, to present insightful commentary about trade credit provision in Ghana. The structured survey questionnaire was administered to 100 construction vendor firms/suppliers to elicit relevant data about their trade credit intentions. Drawing upon the principles of a total design method (TDM) of survey, a relatively high response rate of 57 percent was achieved. Principal component (factor) analysis was adopted to obtain simplification of variables and to detect underlying dimensions and reveal potential complex structures within decision variables.

Findings

The underlying constructs and motives of vendors on trade credit were intricately interwoven in two principal factors: risk distribution and liquidity; and sustaining business relationship and liquidity. Despite the uncharacteristic manifestation of the liquidity measure being associated with the two principal components, the findings demonstrate the relative importance of liquidity in the trade credit debate. A critical observation stemming from the analysis was that trade policy was absent within the trade credit market in Ghana; this poses a potential threat to trade credit exchange and its development.

Originality/value

The paper's methodological approach is uniquely positioned between the conceptual and empirical interface and the overarching research is pioneering within the developing world nation of Ghana. The paper's findings will be useful to contractors, particularly, small and medium size contractors who are considering feasible finance options; and vendors who seek to consolidate their clientele base.

Abstract

Purpose

The purpose of this paper is to investigate the degree of willingness of property developers to invest in green features in Abuja, the federal capital city of Nigeria, to determine the level of their preparedness for green building development.

Design/methodology/approach

Data were elicited from the property managers of the various property development companies through self-administered questionnaire and analyzed with the use of frequency distribution, percentages and measures of developers’ willingness to invest index.

Findings

The study showed that the developers’ level of willingness to invest in green features is above average with the value of willingness indices on most features rising above 2.5 on a five-point scale. Features that are less capital intensive such as “Location of air intake that are far from source of pollution” (RWI = 4.14) and “Building design that utilize natural and cross ventilation” (RWI = 4.12) attracted higher developers’ level of willingness than features such as “Mechanical ventilation of enclosed parking area” (RWI = 2.15) and “Design for energy efficient deconstruction and recycling” (RWI = 1.84) that are more capital intensive. In addition, the index of willingness (relative willingness index of developers) on features that are associated with occupants’ comfort is higher than the index of willingness on features that confer more of environmental benefits.

Practical implications

The study concludes by advocating that parliamentary arms of all tiers of government should formulate environmental policies and laws that will entrench sustainable practices in the building industry in the country.

Originality/value

This is one of the few studies on the willingness of major stakeholders to invest in green features, particularly in the Nigerian context.

Abstract

Purpose

This paper aims to examine general contractors’ experiences of using off-site manufactured structural framing systems. This engaged a single-case study using a qualitative methodology to identify expected benefits, actual benefits and challenges of such systems.

Design/methodology/approach

A single-case study approach evaluated general contractors’ experience of using a manufactured structural framing system. Qualitative data were collated and analyzed from industry domain experts to determine commonalities and thematic thinking.

Findings

The study revealed that the reasons behind considering off-site building systems were: accelerating the project schedule, overcoming site constraints and having a better end-product. The top expected benefits were: saving time (schedule), saving cost and improving quality. The top actual observed benefits were: saving erection time, reducing waste generation, reducing project costs, reducing safety risks and improving construction site logistics. The main challenges encountered were: unfamiliarity of different project parties with the off-site framing system, difficulty with reducing the overall project schedule, heavy site logistics and complicated off-site system design and standards requirements. The findings include solutions to overcome the challenges associated with using a manufactured structural system.

Research limitations/implications

This paper was a case study and therefore inherently limited in its generalizability. The study was conducted with general contractors in the mountain-west region of the USA. However, the implications of the study may have a broad application, as contractors across the globe seek to find similar solutions to using off-site or manufactured construction methods.

Practical implications

Construction labor shortages around the world are forcing the construction industry to find creative solutions to meet the demand for their services. Manufactured or off-site construction methods provide a possible solution to that labor shortage. However, builders need to be aware of the immediate challenges and actual benefits of using a manufactured structural framing system.

Social implications

Manufactured structural framing systems have the potential to impact lean and sustainable practices in construction. Reduced waste, reduced on-site man-power requirements, reduced construction schedules and reduced injuries each improve the lives of construction workers and the communities around these buildings.

Originality/value

An extensive literature review was performed to guide the design of this case study. Much has been written about off-site construction practices, but there is a significant research gap on the topic of structural framing systems. This study contributes to expanding the knowledge of off-site construction and specifically helps researchers and practitioners understand the challenges and benefits of this systematic approach to construction.

Abstract

Purpose

The objective of this work is to demonstrate the relationships between the two main processes of research and development (R&D) activities: the knowledge generation phase (KPP) and the knowledge commercialization, or transfer, phase (KCP), in a sector that is intensive in this type of activity, such as the pharmaceutical sector. In addition, within the framework of the general objective of this work, the authors propose two other objectives: (1) make advances in network efficiency measurement models, and (2) determine the factors associated with efficiency in the KPP and in the KCP in companies of the pharmaceutical sector in Spain.

Design/methodology/approach

A Network Data Envelopment Analysis (NDEA) model (Färe and Grosskopf, 2000) with categorical variables (Lee et al., 2020; Yeh and Chang, 2020) has been applied, and a sensitivity analysis of the obtained results has been performed through a DEA model of categorical variables, in accordance with the work of Banker and Morey (1986), to corroborate the results of the proposed model. The sample is made up of 77 companies in the pharmaceutical sector in Spain.

Findings

The results obtained point to a greater efficiency of pharmaceutical companies in the KPP, rather than in the KCP. Furthermore, the study finds that 1) alliances between companies have been the accelerating factors of efficiency in the KCP (but patents have slowed this down the most); 2) the quality of R&D and the number of R&D personnel are the factors that most affect efficiency in the KPP; and 3) the quality of R&D again, the benefits obtained and the position in the market are the factors that most affect efficiency in the KCP.

Originality/value

The authors have not found studies that show whether the efficiency obtained by R&D-intensive companies in the KPP phase is related to better results in terms of efficiency in the KCP phase. No papers have been found that analyse the role of alliances between R&D-intensive companies and patents, as agents that facilitate efficiency in the KCP phase, covering the gap in the research on both problems. Notwithstanding, this work opens up a research path which is related to the improvement of network efficiency models (since it includes categorical variables) and the assessment of the opinions of those who are responsible for R&D departments; it can be applied to decision-making on the aspects to improve efficiency in R&D-intensive companies.

Abstract

The authors propose to estimate a varying coefficient panel data model with different smoothing variables and fixed effects using a two-step approach. The pilot step estimates the varying coefficients by a series method. We then use the pilot estimates to perform a one-step backfitting through local linear kernel smoothing, which is shown to be oracle efficient in the sense of being asymptotically equivalent to the estimate knowing the other components of the varying coefficients. In both steps, the authors remove the fixed effects through properly constructed weights. The authors obtain the asymptotic properties of both the pilot and efficient estimators. The Monte Carlo simulations show that the proposed estimator performs well. The authors illustrate their applicability by estimating a varying coefficient production frontier using a panel data, without assuming distributions of the efficiency and error terms.
