A prompt CNN-FL model based on multi criteria for a smart vertical handoff in heterogeneous system
Authors: R Ganesan , B Sowmya 
Published: April 2020

PurposeHeterogeneous network is mainly focused to enrich the demands of network's traffic and data rate. Heterogeneous network is an integrated system composed of diverse radio access technologies such as Wi-Fi, UMTS and WiMAX soon. To exchange the packets among these different wireless technologies, an adoptable vertical handoff (VHO) is required.Design/methodology/approachVarious types of techniques have been proposed in line with VHO. However these algorithms lead to the threat of high dropping rate and poor Quality of Service (QoS). We modulate a new methodology by integrating Convolutional Neural Network with Fuzzy Logic (CNN-FL) for an optimum vertical handoff decision process (VHDP). The CNN-FL–based VHDP is very effective because of nonlinearity and generalization capability with uncertain data inputs.FindingsThe performance results exhibit that proposed methods show efficient for selecting the appropriate network with maximum throughput. At the same time, the proposed method reduces computational complexity and dropping rate considerably.Originality/valueThis paper proposes a novel CNN model along with a FL model for achieving a vertical hand off.

Published: April 2020

PurposeThe integration between production scheduling and maintenance planning is attracting the attention of planners in the manufacturing sector with the increase in global competitiveness. Researchers have developed various methodologies to optimize integrated decisions in planning and scheduling, including mathematical modeling under different conditions. This paper considers the simultaneous scheduling of production and maintenance activities with the objective of minimizing the expected total tardiness cost on a single machine (production line).Design/methodology/approachScheduling in these two types of activities, production and maintenance, are traditionally done independently, causing conflicts between the two functional areas. To eliminate or at least reduce conflicts, the scheduling of both activities can be done simultaneously with the objective of meeting due dates and maintaining maximum machine availability. In this paper, a mathematical model for an integrated problem is developed and demonstrated by an example.FindingsThe proposed integrated model shows a high potential for significant improvements in performance with respect to the cost of tardiness in delivery and machine availability. This is demonstrated by an example showing an average savings of approximately 40%.Originality/valueThis substantial saving is owed to the integration of two important decision-making processes in manufacturing systems. Although the integrated problem is complex and difficult to solve, the fact that it is savings driven makes the problem of interest to researchers and practitioners in manufacturing.

Presence of professional accountant in the top management team and financial reporting quality
Authors: Rashid Md Mamunur 
Published: April 2020

PurposeThe purpose of this study is to examine the effect of the presence of professional accountants in the top management team (TMT) on financial reporting quality (FRQ) in public limited companies using the context of Bangladesh, which is an emerging economy.Design/methodology/approachThis study adopts a modified version of Beestet al.’s (2009) FRQ index to measure the quality of information published in 351 annual reports of listed companies in Bangladesh. It also uses a qualitative characteristics approach to measure the quality of financial reporting, as defined by the International Financial Reporting Standards framework 2018, as opposed to an accrual or value relevance approach that solely depends on the information disclosed in the financial statements.FindingsThis study finds that the presence of professional accountants in the TMT is positively and significantly associated with FRQ. The findings also show that the sample companies disclosed better quality information in the enhancing qualitative characteristics category, as compared to the fundamental qualitative characteristics category.Originality/valueThis study uses the context of Bangladesh to explore a new type of relationship between the presence of professional accountants in the TMT and FRQ.
BIM data model requirements for asset monitoring and the circular economy
Authors: Davila Delgado Juan Manuel , Oyedele Lukumon O. 
Published: April 2020

Purpose
The purpose of this paper is to review and provide recommendations to extend the current open standard data models for describing monitoring systems and circular economy precepts for built assets. Open standard data models enable robust and efficient data exchange which underpins the successful implementation of a circular economy. One of the largest opportunities to reduce the total life cycle cost of a built asset is to use the building information modelling (BIM) approach during the operational phase because it represents the largest share of the entire cost. BIM models that represent the actual conditions and performance of the constructed assets can boost the benefits of the installed monitoring systems and reduce maintenance and operational costs.

Design/methodology/approach
This paper presents a horizontal investigation of current BIM data models and their use for describing circular economy principles and performance monitoring of built assets. Based on the investigation, an extension to the industry foundation classes (IFC) specification, recommendations and guidelines are presented which enable to describe circular economy principles and asset monitoring using IFC.

Findings
Current open BIM data models are not sufficiently mature yet. This limits the interoperability of the BIM approach and the implementation of circular economy principles. An overarching approach to extend the current standards is necessary, which considers aspects related to not only modelling the monitoring system but also data management and analysis.

Originality/value
To the authors’ best knowledge, this is the first study that identifies requirements for data model standards in the context current linear economic model of making, using and disposing is growing unsustainably far beyond the finite limits of planet of a circular economy. The results of this study set the basis for the extension of current standards required to apply the circular economy precepts.
Fashion “see-now-buy-now”: implications and process adaptations
Authors: Boardman Rosy , Haschka Yvonne , Chrimes Courtney , Alexander Bethan 
Published: April 2020

PurposeThe purpose of this paper is to identify if and how the see-now-buy-now model impacts the traditional buying, merchandising and supply chain processes (BMSCP) of multi-brand fashion retailers (MBFR) and whether they need to be adapted in order to facilitate this development.Design/methodology/approachThis exploratory study includes three industry case studies, triangulated with external observers. A total of 11 semi-structured interviews were conducted within Germany and the UK.FindingsFindings demonstrate that in order to adopt the see-now-buy-now model there is a need for process-shortening, as well as better process and network alignment between MBFR and brands through agility, supplier–relationship management and vertical integration in order to stay competitive against time-based competition. Whilst most steps of the traditional BMSCP are still applicable under the see-now-buy-now model, they must be re-engineered and shortened, with the steps being rolling rather than linear, with buyers and merchandisers operating in a more hybrid role.Originality/valueThis paper addresses the lack of research on the see-now-buy-now model as well as on the BMSCP of MBFR and the implications that see-now-buy-now could have on those processes. A modified buying, merchandising and supply chain framework adapted to incorporate see-now-buy-now is created which will be useful for academics and practitioners.
Achieving supply chain resilience: the role of supply chain ambidexterity and supply chain agility
Authors: Aslam Haris , Khan Abdul Qadeer , Rashid Kamran , Rehman Saif-ur 
Published: April 2020

PurposeThis study analyzes the role of supply chain ambidexterity (SC-Ambidexterity) in developing supply chain resilience (SC-Resilience). We describe SC-Ambidexterity as a simultaneous application of supply chain adaptability (SC-Adaptability) and supply chain alignment (SC-Alignment) capabilities. We also consider the role of supply chain agility (SC-Agility) in the relationship between SC-Ambidexterity and SC-Resilience. We further suggest that the relationship between SC-Ambidexterity and SC-Resilience may be stronger in case of higher market uncertainty.Design/methodology/approachBased on the dynamic capabilities view (DCV) of the firm, we develop a set of hypotheses that are tested through a survey of manufacturing firms in Pakistan. The hypothesized model is tested through structural equation modeling (SEM).FindingsThe results of this study show a positive effect of SC-Ambidexterity on SC-Resilience. SC-Agility positively mediates the relationship between SC-Ambidexterity and SC-Resilience. However, our results show that this relationship does not vary at different levels of environmental uncertainty.Originality/valueThis study provides the seminal operationalization of SC-Ambidexterity in the supply chain context. It further shows the importance of SC-Ambidexterity and SC-Agility in contributing toward SC-Resilience.
Performing technical analysis to predict Japan REITs' movement through ensemble learning
Authors: Loo Wei Kang 
Published: April 2020

PurposeThe purpose of this study is to evaluate the performance of the ensemble learning models, such as the Random Forest and Extreme Gradient Boosting models, in predicting the direction of the Japan real estate investment trusts (J-REITs) at different return horizons, based on input obtained from various technical indicators.Design/methodology/approachThis study measures the predictability of J-REITs with technical indicators by using different horizons of REITs' return and machine learning models. The ensemble learning models includes Random Forest and Extreme Gradient Boosting models while the return horizons of REITs ranging from 1 to 300 days. The results were further split into individual years to check for the consistency of the performance across time.FindingsThe Extreme Gradient Boosting appears to be the best method in improving forecast accuracy but not the trading return. A wider return horizons platform seemed to deliver a relatively better performance in both forecast accuracy and trading return, when compared to the return horizon of one.Practical implicationsIt is recommended that the Extreme Gradient Boosting and Random Forest model be considered by practitioners for back-testing trading model. In addition, selecting different return horizons so as to achieve a better performance in trading/investment should also be considered.Originality/valueThe predictability of J-REITs using technical indicators was compared among different returns horizons and the models (Extreme Gradient Boosting and Random Forest).
Is the MD&A of US REITs informative? A textual sentiment study
Authors: Koelbl Marina 
Published: April 2020

PurposeThis study examines whether language disclosed in the Management Discussion and Analysis (MD&A) of US Real Estate Investment Trusts (REITs) provides signals regarding future firm performance and thus generates a market response.Design/methodology/approachThis research conducts textual analysis on a sample of approximately 6,500 MD&As of US REITs filed by the SEC between 2003 and 2018. Specifically, the Loughran and Mcdonald (2011) financial dictionary, and a custom dictionary for the real estate industry created by Ruscheinsky et al. (2018), are employed to determine the inherent sentiment, that is, the level of pessimistic or optimistic language for each filing. Thereafter, a panel fixed-effects regression enables investigating the relationship between sentiment and future firm performance, as well as the markets’ reaction.FindingsThe empirical results suggest that higher levels of pessimistic (optimistic) language in the MD&A predict lower (higher) future firm performance. Hereby, the use of a domain-specific real estate dictionary, namely that developed by Ruscheinsky et al. (2018) leads to superior results. Corresponding to the notion that the human psyche is affected more strongly by negative than positive news (Rozin and Royzman, 2001), the market responds solely to pessimistic language in the MD&A.Practical implicationsThe results suggest that the market can benefit from textual analysis, as investigating the language in the MD&A reduces information asymmetries between US REIT managers and investors.Originality/valueThis is the first study to analyze exclusively US REITs, whether language in the MD&A is predictive of future firm performance and whether the market responds to textual sentiment.

Published: April 2020

PurposeThe decision to buy a holiday home depends on a number of social, cultural, economic and demographic factors. These factors are related to home and environmental characteristics as well as demographic characteristics of buyers. The aim of this paper is to investigate the factors that shape the decision to purchase a holiday home in Greece.Design/methodology/approachThis paper presents the results of a survey, involving a representative sample of potential buyers of holiday homes in Greece.FindingsAccording to the research results, buying a holiday home in Greece is mainly an investment decision for the future and is determined by the value and characteristics of the house, the hidden costs and the factors that shape the external economic environment. (1) Further, the analysis has shown that there is a limited use of electronic channels in the real estate market in Greece with further potential of development.Originality/valueThe investigation focuses on the characteristics of the house, the variables of the external environment, (2) considering any obstacles or catalysts, such as the use of electronic channels. Even though similar studies have been conducted worldwide on the topic, very few have been carried out in Greece which lately has gone through major market changes.
Coordination difficulties and self‐esteem: The views of children, adolescents, and their parents
Authors: Eggleston Matthew , Watkins William , Frampton Christopher , Hanger Nicola 
Published: April 2020

AbstractIntroductionThis study aimed to examine the views of children and adolescents with significant coordination difficulties, and their parents, regarding factors they considered had most supported and hindered the development of their self‐esteem (SE).MethodsA survey was sent to members of the Dyspraxia Support Group of New Zealand asking participants to prioritise the three factors that had most positively and negatively influenced the development of the young person's SE. Quantitative content analysis was utilised to summarise responses in order to describe main influences.ResultsBoth groups rated love and support from family as an important factor that had promoted SE. Young people placed more emphasis than parents on friendship and rewarding activities. Parents emphasised the importance of a supportive school environment and the benefits of “diagnosis.” Both groups frequently rated aspects directly related to coordination difficulties and bullying as negative influences on SE.ConclusionThe results provide information for young people with coordination difficulties, their parents, and occupational therapists regarding useful strategies for developing healthy SE. Occupational therapists have a critical role in the assessment of children and adolescents with coordination difficulties which leads to better understanding of the young person by others. Additionally, task‐oriented treatment approaches are indicated and are likely to lead to increased rates of participation of young people in rewarding activities, including with friends. Further research is required to determine whether these occupational therapy interventions promote increases in SE.
Taming the flagellar motor of pseudomonads with a nucleotide messenger
Authors: Ma Guang‐Lei , Chandra Hartono , Liang Zhao‐Xun 
Published: April 2020

SummaryPseudomonads rely on the flagellar motor to rotate a polar flagellum for swimming and swarming, and to sense surfaces for initiating the motile‐to‐sessile transition to adopt a surface‐dwelling lifestyle. Deciphering the function and regulation of the flagellar motor is of paramount importance for understanding the behaviours of environmental and pathogenic pseudomonads. Recent studies disclosed the preeminent role played by the messenger c‐di‐GMP in controlling the real‐time performance of the flagellar motor in pseudomonads. The studies revealed that c‐di‐GMP controls the dynamic exchange of flagellar stator units to regulate motor torque/speed and modulates the frequency of flagellar motor switching via the chemosensory signalling pathways. Apart from being a rotary motor, the flagellar motor is emerging as a mechanosensor that transduces surface‐induced mechanical signals into an increase of cellular c‐di‐GMP concentration to initiate the cellular programs required for long‐term colonization. Collectively, the studies generate long‐awaited mechanistic insights into how c‐di‐GMP regulates bacterial motility and the motile‐to‐sessile transition. The new findings also raise the fundamental questions of how cellular c‐di‐GMP concentrations are dynamically coupled to flagellar output and the proton‐motive force, and how c‐di‐GMP signalling is coordinated spatiotemporally to fine‐tune flagellar response and the behaviour of pseudomonads in solutions and on surfaces.
The influence of calculative (“hard”) and collaborative (“soft”) HRM on the layoff‐performance relationship in high performance workplaces
Authors: Cregan Christina , Kulik Carol T. , Johnston Stewart , Bartram Timothy 
Published: April 2020

AbstractWe investigate the effect of employment systems on the layoff‐performance relationship. We construct a typology of two types of HPWS (Calculative or “hard” HRM and Collaborative or “soft” HRM) and two non‐high performance systems (Traditional HRM and Low HRM). We use attribution theory as a framework from which to draw hypotheses. We examine survey responses from two waves of panel data. We employ cluster analysis to identify distinctive configurations of employment practices used in UK workplaces. We use the cluster outcomes as explanatory variables in moderator regression analysis. Following layoffs, we find that Calculative workplaces experience lower subsequent performance than Collaborative workplaces. Over the next five years, Calculative and Collaborative workplaces experience equivalent amounts of performance change but Calculative workplaces fail to make a full recovery.
Nutrients and Heavy Metals in Legacy Sediments: Concentrations, Comparisons with Upland Soils, and Implications for Water Quality
Authors: Lutgen Alyssa , Jiang Grant , Sienkiewicz Nathan , Mattern Katie , Kan JinJun , Inamdar Shreeram 
Published: April 2020

AbstractConcentrations of nutrients and heavy metals in streambank legacy sediments are needed to estimate watershed exports and to evaluate against upland inputs. Concentrations of nutrients and heavy metals were determined for legacy sediments in 15 streambanks across northeastern Maryland, southeastern Pennsylvania, and northern Delaware. Samples were collected from multiple bank depths from forested, agricultural, urban, and suburban sites. Analyses were performed for fine (<63 μm) and coarse sediment fractions. Nutrient and heavy metal concentrations were significantly higher in fine than coarse legacy sediments and water extractable nutrient concentrations were significantly greater for fine sediments. Nutrient and heavy metal concentrations were highest in streambank legacy sediments associated with urban land use, but few differences were found with bank depth. Total N (40–3,970 mg/kg) and P (25–1,293 mg/kg) and bioavailable P (0.25–48.8 mg/kg) concentrations for legacy sediments were lower than those for upland soils. This suggests that legacy sediments could serve as sink or source of N and P depending on the redox conditions and stream water nutrient concentrations. However, despite low concentrations, caution should be exercised since streambank erosion and legacy sediment mass loadings could be high, these sediments are in immediate proximity of aquatic ecosystems, and biogeochemical transformations could result in release of the nutrients.
