Critical success factors for BIM implementation: a Malaysian case study
Authors: Sinoh Saznizam Sazmee , Othman Faridah , Ibrahim Zainah 
Published: May 2020

PurposeThis paper aimed to identify critical success factors (CSFs) of building information modeling (BIM) implementation among architectural, engineering and construction (AEC) firms in Malaysia using quantitative statistical methods.Design/methodology/approachA questionnaire survey was conducted on the population of all AEC firms in Malaysia to rank the relative importance of 15 success factors (SFs) for BIM implementation in the firm on a 5-point Likert scale. The sampling frame consisted of all members registered with the Construction Industry Development Board (CIDB) from which 184 responses were received. The distinction between SFs and CSFs was achieved by a normalized mean cutoff value. Principal component analysis (PCA) was used to determine the relative groupings of the CSFs and structural equation modeling (SEM) were used to examine the underlying relationships between the CSF groupings.FindingsResults of this study validated 11 previously identified CSFs for successful implementation of BIM among Malaysian AEC firms. Non-technical factors such as management, leadership and coordination were found to have higher relevance compared to technical factors such as software and hardware. Ranking analysis of the CSFs found internal coordination factors to have more importance compared to external coordination factors. PCA revealed 4 principal components (PCs) from the 11 CSFs. Together, these four PCs explain 74.3% of the variance in the data. Also, six hypothesized relationships between these groupings were supported using PLS-SEM.Research limitations/implicationsThis study found an interaction between internal and external coordination factors for the implementation of BIM. Future research could explore the dynamics of both intra- and inter-firm coordination, which may create an environment suitable for BIM implementation.Practical implicationsThis study provides Malaysian AEC firms with a general strategy on how to approach the implementation of BIM within the firm. In addition, government initiatives should focus on increasing BIM competency of graduates entering the workforce. This can be achieved through the development of a national BIM curriculum. Apart from that, the implementation of BIM requires a radical shift in the traditional building delivery process, not just simply acquiring new software and hardware.Originality/valueThis study revealed that the interactions between different firms at the industry level can influence successful implementation of BIM at the firm level. CSFs for BIM implementation at the firm level have been extensively studied. However, few studies exist which explore the inter-firm collaborations at the industry level that facilitate successful BIM implementation.

Authors: Liu Andy Xiaofeng , Hsu Cathy H.C. , Fan Daisy X.F. 
Published: May 2020

Purpose
This study aims to examine the mechanism of how hotel executive brand identity influences physical facility quality, customer-based brand equity (CBBE) and employee-based brand equity (EBBE).

Design/methodology/approach
The study introduces a multilevel model and collects 925 executive and 1,978 employee responses from 62 upscale hotels in China.

Findings
Executive brand identity positively affects employee brand internalization, which leads to positive EBBE. Meanwhile, executive brand identity positively influences the physical facility quality, which leads to positive CBBE.

Originality/value
This study considers the tangible (physical facilities) and intangible (employees) elements of hotel services to comprehensively investigate the brand equity formation. By applying multilevel structural equation modeling, the study examines the bidirectional relationship between organizations and employees in the brand value transformation process.
Different stages of the e-service delivery system process: belief–attitude–intention framework
Authors: Gupta Piyush , Sachan Amit , Kumar Rajiv 
Published: May 2020

PurposeBased on social science theories of customer's action such as theory of planned behaviour, theory of reasoned action, and technology acceptance model, this paper adopts belief–attitude–intention model to study impact of perceived process-belief of different stages of e-service delivery system process (e-SDSP), i.e., searching process belief (SPB), agreement process belief (APB), fulfilment process belief (FPB) and after-sales service process belief (ASPB) on customer attitude and intention towards service providers. The study also focuses on the mediating effect of customer attitude on the relationship between process-beliefs of different stages of e-SDSP and their behavioural intention.Design/methodology/approachA quantitative method has been employed using data collected from 414 Indian e-retail customers. Structural equation modelling with bootstrap estimation is used to find the mediating effect of attitude.FindingsThe findings suggest that SPB and ASPB directly impact the customer attitude while APB and FPB directly impact the customer behavioural intention. The study also finds that customer attitude towards e-retailers fully mediates the effect of SPB and ASPB on the behavioural intention but there are no mediating effects for APB and FPB.Research limitations/implicationsThe sample used may not be generalizable for India, given its huge diversity and population. As the sample considers only Indian e-retail customers, this study may lack generalizability across countries.Originality/valueIn our knowledge, this study is the first step to conceptualize the process-oriented customer's perceived belief of different stages of e-SDSP and how these beliefs impact the customers' attitude and intention towards the e-retailers. The findings offer insight to managers on how they can create and cultivate customer happiness and positive behavioural intention by enhanced customer journey throughout the e-SDSP.
Loyalty cards, credit options and economic market development
Authors: Zielke Stephan , Komor Marcin 
Published: May 2020

PurposeThis paper analyses three strategies in customers’ use to afford consumption in a developed and an emerging market for different product groups. The strategies are: (1) usage of loyalty cards, (2) usage of credit cards and (3) usage of long-term credits.Design/methodology/approachMall intercept surveys conducted in Poland (emerging market) and Germany (developed market) provide data for testing a set of hypotheses using ANOVAs.FindingsResults show that customers in emerging markets show no differences in the usage of loyalty cards for product categories with high shopping frequency (groceries) compared to developed markets, while in all other product categories loyalty card usage is stronger. Results show further that in low price categories, customers in emerging markets use credit card payments more often compared to customers in developed markets. In high price categories, they use credit cards less often, but long-term credits more often.Research limitations/implicationsResults have implications for the design of loyalty programs and payment options in different markets. Results have also implications for public policy regarding concerns about increasing private debt in emerging countries.Originality/valueThis paper suggests a cost-benefit framework where customers in emerging countries perceive benefits of loyalty cards and credit options higher, while they are willing to bear higher costs. As a result, effects of product category characteristics on usage that are observable in developed markets do not exist in emerging markets.

Published: May 2020

PurposeThe purpose of this paper is to discuss the 3D micropolar hybrid (Ag-CuO/H2O) nanofluid past rapid moving surface, where porous medium has been considered.Design/methodology/approachThe model of problem was represented by highly partial differential equations which were deduced by using suitable approximations (boundary layer). Then, the governing model was converted into five combined ordinary differential equations applying proper similarity transformations. Therefore, the eminent iterative Runge–Kutta–Fehlberg method (RKF45) has been applied to solve the resulting equations.FindingsHigher values of vortex viscosity, spin gradient viscosity and micro-inertia density parameters are reduced in horizontal direction, whereas opposite behaviour is noticed for vertical direction.Originality/valueThe work has not been done in the area of hybrid micropolar nanofluid. Hence, this article culminates to probe how to improve the thermal conduction and fluid flow in 3D boundary layer flow of micropolar mixture of nanoparticles driven by rapidly moving plate with convective boundary condition.
Business founding in biotech industry: process and features
Authors: Ciao Biagio 
Published: May 2020

PurposeThis paper aims to construct a process model of business founding in the biotech industry.Design/methodology/approachAn inductive method is used, and five case studies analyzed. Data are coded by applying Gioia’s method.FindingsAspirant entrepreneurs conduct resource analysis and industry analysis to formulate research and development targets. They perform transactions and networks because they require resources, and they then deploy and coordinate these resources. Such coordination generates activities with social and financial impacts.Research limitations/implicationsThe results are specific to the biotech industry. A future study could examine business founding processes in other industries (e.g. entertainment, fashion, public utilities and sport). Additionally, the paper argues that during the founding process entrepreneurs show little concern for knowledge-sharing risk, as they want to collaborate to implement their ideas. Quantitative papers could test the consequences of such behavior.Practical implicationsThe process model provides insights into aspirant founders on how to start a business in the biotech industry.Originality/valueThe paper shows: the differences between the founding process in the biotech industry versus other industries; and the shape of the Bower–Burgelman model in the context of biotech business founding. The paper delineates how private companies discover competencies in the public sector; a model of technology transfer from public to private sector; entrepreneurs’ absence of risk perceptions regarding knowledge-sharing during founding; and how conferences can serve as vehicles for benchmarking in networking.

Purpose
Among soy products, soy ice cream with neutral pH, high total solids contents and prebiotic oligosaccharides is an appropriate vehicle for probiotics. The purpose of this paper is to survey soy ice cream as a carrier for the efficient delivering of Lactobacillus casei, or L. casei.

Design/methodology/approach
Probiotic soy ice cream containing L. casei was produced via the powder of soy milk. The physicochemical and organoleptic properties of the product were assessed. Also, the viability of L. casei was surveyed over a 180-day period of storage at −25 °C.

Findings
The density characteristic of probiotic soy ice cream demonstrated a significant rise (P < 0.05). The result of the viability analysis showed significant alterations in the number of probiotics in this product after freezing and throughout the 180-day period (P < 0.05). The most noticeable drop was seen throughout the first 60 days about 1.83 logs after that the trend of survival of this probiotic strain leveled off over the next 120 days. Also, no significant differences were found in the organoleptic properties of both ice creams.

Originality/value
Soy ice cream with prebiotic elements protected the growing and activity of probiotic bacteria. The results showed that L. casei is a good probiotic for soy ice cream.

Authors: Tian Pu , Yan Ruosi , Tong Yabiao , Jia Lixia , Yao Jiming 
Published: May 2020

Purpose
The purpose of this paper is to investigate the effects of alkali treatment on adhesion of industrial thermoplastic polyurethane elastomer (TPU)/polyester woven fabric inter-ply hybrid composites.

Design/methodology/approach
Inter-ply hybrid composites were exposed to varying concentration of sodium hydroxide at different temperature and time and their mechanical properties including differential scanning calorimetry, scanning electron microscope, tensile and peeling strength evaluated to determine optimal treatment parameters.

Findings
Modified polyester fabrics treated with alkali had higher tensile and peeling strengths. Accordingly, alkali treatment roughened the surface of polyester fabric, decreasing warp and weft densities, thus increasing fiber surface energy. The fabric had the highest peeling strength of 3.23 N/mm at treatment of 25% concentration of sodium hydroxide (NaOH). Short-term exposure to ultraviolet had little effect on interfacial adhesion of alkali-treated conveyor belt.

Research limitations/implications
Polyester fabric, applied in reinforcing industrial conveyor belts, is never degreased, roughened, sensitized or activated. In this paper, one-step treatment of polyester fabric was performed to increase its adhesion with polyester inter-ply hybrid composites, providing a reference for practical industrial application.

Practical implications
The method developed in this research is simple and provides a solution to improving the interfacial adhesion of TPU/polyester conveyor belt.

Originality/value
The novel alkali treatment technology has many applications in the interfacial performance of composite materials.
Optimization of friction stir welding process parameters for AA6063-ETP copper using central composite design
Authors: Panaskar Nitin , Terkar Ravi Prakash 
Published: May 2020

Purpose
Recently, several studies have been performed on lap welding of aluminum and copper using friction stir welding (FSW). The formation of intermetallic compounds at the weld interface hampers the weld quality. The use of an intermediate layer of a compatible material during welding reduces the formation of intermetallic compounds. The purpose of this paper is to optimize the FSW process parameters for AA6063-ETP copper weld, using a compatible zinc intermediate filler metal.

Design/methodology/approach
In the present study, a three-level, three-factor central composite design (CCD) has been used to determine the effect of various process parameters, namely, tool rotational speed, tool traverse speed and thickness of inter-filler zinc foil on ultimate tensile strength of the weld. A total of 60 experimental data were fitted in the CCD. The experiments were performed with tool rotational speeds of 1,000, 1,200 and 1,400 rpm each of them with tool traverse speeds of 5, 10 and 15 mm/min. A zinc inter-filler foil of 0.2 and 0.4 mm was also used. The macrograph of the weld surface under different process parameters and the tensile strength of the weld have been investigated.

Findings
The feasibility of joining 3 mm thick AA6063-ETP copper using zinc inter-filler is established. The regression analysis showed a good fit of the experimental data to the second-order polynomial model with a coefficient of determination (R2) value of 0.9759 and model F-value of 240.33. A good agreement between the prediction model and experimental findings validates the reliability of the developed model. The tool rotational speed, tool traverse speed and thickness of inter-filler zinc foil significantly affected the tensile strength of the weld. The optimal conditions found for the weld were, rotational speed of 1,212.83 rpm and traverse speed of 9.63 mm/min and zinc foil thickness is 0.157 mm; by using optimized values, ultimate tensile strength of 122.87 MPa was achieved, from the desirability function.

Originality/value
Aluminium and copper sheets could be joined feasibly using a zinc inter-filler. The maximum tensile strength of joints formed by inter-filler (122.87 MPa) was significantly better as compared to those without using inter-filler (83.78 MPa). The optimum process parameters to achieve maximum tensile strength were found by CCD.
The relative importance of green infrastructure as refuge habitat for pollinators increases with local land‐use intensity

Published: May 2020

Abstract

Agricultural expansion and intensification have resulted in strong declines in farmland biodiversity across Europe. In many intensively farmed landscapes, linear landscape elements such as field boundaries, road verges and ditch banks are the main remaining green infrastructures providing refuge for biodiversity, and as such play a pivotal role in agri‐environmental policies aiming at mitigating biodiversity loss. Yet, while we have a fairly good understanding of how agricultural intensification influences biodiversity on farmland, little is known about whether and how local land‐use intensity affects biodiversity in nearby linear landscape elements and how this affects their role as biodiversity refuge.

Focussing on pollinating insects, we examined the effects of local land‐use intensity on biodiversity in agricultural fields and adjacent green infrastructures. In an intensively farmed area in south‐western France, we selected 23 agricultural grasslands and nearby field boundaries along a gradient in grassland cutting frequency which acted as a proxy for land‐use intensity. We analysed how grassland cutting frequency affects species richness, abundance and community composition of wild bees and hoverflies in the grasslands and neighbouring field boundaries, and whether these effects differ across habitat types and species groups.

Grassland cutting frequency negatively affected pollinator species richness and abundance in the grasslands, whereas pollinators in the neighbouring field boundaries were unaffected. These responses reflected the effects of cutting frequency on floral resources, with flower cover and richness decreasing in grasslands but not in field boundaries. As a result, the proportion of the local pollinator community supported by field boundaries increased with the increasing cutting frequency of the adjacent grassland.

Common and rare pollinator species generally showed similar responses. Furthermore, communities of plants and pollinators in field boundaries next to intensively farmed grasslands were fairly similar to those next to extensively farmed ones.

Synthesis and applications. Our results suggest that, as nearby land use intensifies, flower‐rich field boundaries become increasingly important as pollinator refuge habitats. Conserving field boundaries and other green infrastructures, and maintaining or enhancing their quality, therefore constitute important tools to conserve and promote pollinators in intensively farmed landscapes.

Published: May 2020

AbstractLung ultrasound (LUS) plays a critical role in the SARS‐CoV‐2 pandemic. Evidence is mounting on its utility to diagnose, assess the severity and as a triage tool in the ED. Sonographic features correlate well to computed tomography (CT) chest findings and a bedside LUS performed by a trained clinician along with clinical examination, could be an alternative to chest X‐ray and CT chest in these highly infectious patients. In this article, we have described a step‐by‐step approach to LUS in COVID patients and the CLUE (COVID‐19 LUS in the ED) protocol, which involves an anatomical parameter, the severity of lung changes, objectively scored using the validated LUS scoring system and a physiological parameter, oxygen requirement. We believe this CLUE protocol can help risk‐stratify patients presenting to ED with suspected COVID‐19 and aid clinicians in making appropriate disposition decisions.

AbstractIntroductionInnovative biomarkers to predict treatment response in rectal cancer would be helpful in optimizing personalized treatment approaches. In this study, we aimed to develop and validate a CT‐based radiomic imaging biomarker to predict pathological response.MethodsWe used two independent cohorts of rectal cancer patients to develop and validate a CT‐based radiomic imaging biomarker predictive of treatment response. A total of 91 rectal cancer cases treated from 2009 to 2018 were assessed for the tumour regression grade (TRG) (0 = pathological complete response, pCR; 1 = moderate response; 2 = partial response; 3 = poor response). Exploratory analysis was performed by combining pre‐treatment non‐contrast CT images and patterns of TRG. The models built from the training cohort were further assessed using the independent validation cohort.ResultsThe patterns of pathological response in training and validation groups were TRG 0 (n = 14, 23.3%; n = 6, 19.4%), 1 (n = 31, 51.7%; n = 15, 48.4%), 2 (n = 12, 20.0%; n = 7, 22.6%) and 3 (n = 3, 5.0%; n = 3, 9.7%), respectively. Separate predictive models were built and analysed from CT features for pathological response. For pathological response prediction, the model including 8 radiomic features by random forest method resulted in 83.9% accuracy in predicting TRG 0 vs TRG 1–3 in validation.ConclusionThe pre‐treatment CT‐based radiomic signatures were developed and validated in two independent cohorts. This imaging biomarker provided a promising way to predict pCR and select patients for non‐operative management.
Earnings Forecasts and Price Efficiency after Earnings Realizations: Reduction in Information Asymmetry through Learning from Price*
Authors: Gong Guojin , Qu Hong , Tarrant Ian 
Published: May 2020

ABSTRACTWhen information asymmetry is a major market friction, earnings forecasts can lead to higher price efficiency even after the information in forecasts completely dissipates upon earnings realizations. We show this in an experimental market that features information asymmetry (i.e., some traders possess differential private information). Earnings forecasts reduce information asymmetry and lead to prices that reflect a greater amount of private information. Traders can learn more about others' information from prices. This information learned from past prices continues to reduce information asymmetry and improve price efficiency even after earnings realizations. We contribute to the disclosure literature by showing the evidence that the learning‐from‐price effect amplifies the impact of public disclosure on price efficiency.
