Published: May 2018

Purpose
The purpose of this paper is to present an exploratory study which aims to assess the potential use of 3D mapping of buildings and construction sites using unmanned aerial system (UAS) imagery for supporting the construction management tasks.

Design/methodology/approach
The case studies were performed in two different residential construction projects. The equipment used was a quadcopter equipped with digital camera and GPS that allow for the registry of geo-referenced images. The Pix4D Mapper and PhotoScan software were used to generate the 3D models. The study sought to examine three main constructs related to the 3D mapping developed: the easiness of development, the quality of the models in accordance with the proposed use and the usefulness and limitations of the mapping for construction management purposes.

Findings
The main contributions of this study include a better understanding of the development process of 3D mapping from UAS imagery, the potential uses of this mapping for construction management and the identification of barriers and benefits related to the application of these emerging technologies for the construction industry.

Originality/value
The importance of the study is related to the initiative to identify and evaluate the potential use of 3D mapping from UAS imagery, which can provide a 3D view of the construction site from different perspectives, for construction management tasks applications, trying to bring positive contributions to this knowledge area.

Mentoring associate teachers in initial teacher education: the value of dialogic feedback
Authors: Jones Luke , Tones Steven , Foulkes Gethin 
Published: May 2018

Purpose
The purpose of this paper is to analyse feedback in the context of secondary initial teacher education (ITE) in England. More specifically, it aims to examine the feedback experiences of physical education (PE) subject mentors and their associate teachers (ATs) during a one-year postgraduate programme.

Design/methodology/approach
Semi-structured interviews, with nine PE mentors and 11 ATs within a university ITE partnership, were used to explore lesson feedback and the context in which it was provided. Interview data from the 20 participants were analysed through constant comparison to categorise content and identify patterns of responses.

Findings
Mentors were well versed in the formal feedback mechanism of a written lesson observation. This approach is well established and accepted within ITE, but the dialogic feedback that follows lessons was thought to be where ATs made most progress. These learning conversations were seen to provide less formal but more authentic feedback for those learning to teach, and were most successful when founded on positive and collaborative relationships between the mentor and the ATs.

Practical implications
These findings have implications for providers of teacher education and more specifically how they approach mentor training. The focus on lesson observations has value, but examining more informal dialogic approaches to feedback may have more impact on the learning of ATs.

Originality/value
These findings support the value of lesson feedback but challenge the primacy of formal written lesson observations. The learning conversations that follow lessons are shown to provide authentic feedback for ATs.
A preventive conservation approach for historical timber roof structures
Authors: Van Roy Nathalie , Verstrynge Els , van Balen Koenraad 
Published: May 2018

PurposeThe purpose of this paper is to illustrate the assets of a preventive conservation approach for historical timber roof structures, as a means to improve the quality and durability of maintenance and repair interventions.Design/methodology/approachThe advantages of a preventive approach for historical structures were identified based on two analyses: a study of the structures’ behaviour and an investigation of existing approaches in current practice. The two main identified advantages of the approach, the cyclic process-approach and the potential of knowledge enhancement, were hereafter conceptually implemented in existing approaches.FindingsCurrent practices focus on single curative interventions, and monitoring is often considered redundant. The importance of monitoring and knowledge enhancement is demonstrated based on the theory of complex adaptive systems (CAS). A preventive conservation approach for historic timber roof structures allows integrating these insights.Research limitations/implicationsThe analysis of current practice is a sample survey, and the proposed preventive conservation approach is presented at a conceptual level. Future research foresees a more elaborated study of current practice and detailed validation of the developed approach.Originality/valueThree new contributions to the existing research on preventive conservation are: arguments for the implementation of a preventive approach, based on an analysis of the structures’ behaviour; the identification of limitations of current approaches that can be tackled in a preventive conservation approach; and the integration of the existing international guidelines and the principles of preventive conservation into a conceptual approach for the monitoring and management of these structures. Furthermore, the research paper demonstrates how timber structures can be understood as CAS, which is a novel viewpoint.
Corporate governance, risk and efficiency: evidence from GCC Islamic banks
Authors: Ben Zeineb Ghada , Mensi Sami 
Published: May 2018

PurposeThe purpose of this paper is to determine the simultaneous effect of corporate governance (CG) of Gulf Cooperation Council (GCC) Islamic banks (IBs) on efficiency and risk.Design/methodology/approachThe authors include Shariah supervisory board (SSB) size, Chief Executive Officer (CEO)-duality and ownership structure as CG variables. Efficiency and risk are measured using the data envelopment analysis (DEA)/stochastic frontier analysis (SFA) andZ-score, respectively. This paper also examines the risk-efficiency relationship. To test the hypotheses, the authors used seemingly unrelated regressions on a sample of 56 GCC IBs during the period 2004-2013.FindingsThe results indicate that implementing rigorous CG structures correlate with higher efficiency levels. Particularly, the authors show that the governance structure of IBs allows them to take higher risks to achieve a high efficiency level. In addition, results show that bank efficiency and risk are positively related.Practical implicationsThis paper gives some insights to policy makers. It points out detail attention toward the importance of CG in IB that influences the efficiency level and risk-taking behavior. Thus, IB should improve governance procedures that can lead to higher efficiency and survival in a competitive environment and sustain financial crisis. Moreover, the economic conditions of a country are the main determinant of an IB’s efficiency and risk relationships.Originality/valueThe simultaneous effect of the CG of the GCC IBs on efficiency and risk is examined, taking into consideration different CG proxies, i.e., SSB size, CEO-duality and ownership structure, and different efficiency estimation techniques, i.e., SFA and DEA.
Typology of social media followers: the case of luxury brands
Authors: Ramadan Zahy , Farah Maya F. , Dukenjian Armig 
Published: May 2018

Purpose
Luxury brands tend to be hesitant in adopting social media. This matter has created an imminent need to understand the different types of online luxury followers so as to help luxury brands communicate effectively with their consumers, while maintaining the “luxe” image and experience. Accordingly, the purpose of this paper is to provide luxury brands with a deeper understanding of their online audience and the strategies needed to engage with them through the different social media platforms.

Design/methodology/approach
A qualitative approach was utilized in which 24 in-depth interviews were conducted with Lebanese followers of an online luxury brand’s social media pages.

Findings
The study identifies the presence of six main categories of online luxury followers: pragmatists, bystanders, trend hunters, image seekers, passionate owners, and prime consumers. Each group has a specific engagement and propensity to buy levels.

Research limitations/implications
Understanding the different segments of luxury brand followers provides a framework for marketing managers that allows them to correctly target their marketing and communication strategies in order to maximize consumer engagement and purchasing behaviors.

Originality/value
A significant gap exists in the extant literature which offers no understanding of the different luxury brand followers and their different characteristics. This study is the first to offer an exploratory typology of the various luxury brand followers on social media platforms.
Do ‘his’ education and class matter? The changing effect of the husband on women's labour‐market transitions in Italy and Britain
Authors: Solera Cristina 
Published: May 2018

AbstractA new stream of sociological and demographic theory emphasizes individualization as the key process in late modernity. As maintained by Hakim (), women also have increasingly become agents of their own biographies, less influenced by the social class and the family. In this study, I intend to contribute to this debate by analysing how, in Italy and Britain, women's movements between employment and housework are linked to their husband's education and class, and how this link has changed across cohorts. Using discrete‐time event‐history modelling on the BHPS and ILFI, my findings show that in both countries, if the woman's educational and labour‐market profile is controlled for, the husband's occupation and education have lost importance. Yet, although based more on ‘her’ than ‘his’ profile, divisions along ‘classic’ lines are still evident and not context‐free, and they assume different forms in the two countries with distinctive institutional and cultural settings. In ‘liberal’ Britain, women's labour‐market participation responds more to motherhood and class than to education, while in ‘familistic’ Italy education seems more important, which suggests the existence of returns over and above strictly human capital/economic ones.
Can cultural consumption increase future earnings? Exploring the economic returns to cultural capital
Authors: Reeves Aaron , de Vries Robert 
Published: May 2018

AbstractCultural consumption is often viewed as a form of embodied cultural capital which can be converted into economic rewards (e.g., earnings) because such practices increase the likelihood of moving into more advantaged social positions. However, quantitative evidence supporting this theory remains uncertain because it is often unable to rule out alternative explanations. Cultural consumption appears to influence hiring decisions in some elite firms, in both the US and the UK, but it is unclear whether these processes are applicable to other professional occupations and other labour market processes, such as promotions. We examine these processes using data from Understanding Society, an individual‐level panel survey conducted in the UK, allowing us to explore whether cultural consumption predicts future earnings, upward social mobility and promotions. People who consume a larger number of cultural activities are more likely to earn higher wages in the future, to be upwardly socially mobile, and to be promoted. Cultural consumption, then, can function as cultural capital in some labour market settings, potentially contributing to the reproduction of income inequality between generations.

Published: May 2018

Biofilm formation by 30 Staphylococcus aureus dairy isolates and their control by phytochemicals were investigated. The majority of strains were biofilm positive by phenotypic analysis. The nuc and icaA genes were present in 30 and 27 strains, respectively. In addition, 13 strains were positive for all nuc, clfA, fnbA and icaA genes. The antimicrobial and antibiofilm activities of citral, cinnamaldehyde, eugenol, farnesol, limonene and terpinen‐4‐ol were also evaluated for seven strains. It was shown that the use of farnesol, cinnamaldehyde or terpinen‐4‐ol at a concentration of 2 mg/mL could be at least 80% effective on S. aureus strains and their biofilms.
Growing Reinsurance Payments Weaken Competitive Bidding in Medicare Part D
Authors: Jung Jeah , Feldman Roger 
Published: May 2018

ObjectivesTo examine variation in risk‐adjusted reinsurance payments across Part D plans, analyze its implications for the program, and explore options to reduce reinsurance payments.Data/Study Design2007–2015 Part D Plan Payment and Premium data; 2010–2013 Part D Prescription Drug Event data; and 2013 Part D Plan Formulary Files.Principal FindingsRisk‐adjusted reinsurance payments varied widely across plans at a given out‐of‐pocket (OOP) premium. The variance in risk‐adjusted reinsurance in common OOP premium ranges increased between 2010 and 2015. High risk‐adjusted reinsurance payments were negatively correlated with use of utilization management tools for high‐cost drugs.ConclusionsGrowing reinsurance payments shrink plans’ liability for managing drug spending for high‐cost enrollees, creating plan moral hazard, and making OOP premiums a noisy signal of plans’ total costs.
Summary annual reports: length, readability and content
Authors: Bradbury Michael E. , Hsiao Pei___Chi Kelly , Scott Tom 
Published: May 2018

AbstractThis paper examines summary annual reports (SAR) as an alternative channel for communicating financial information. We use a sample of New Zealand local governments (councils) that are required to report audited SAR. Using various measures, we compare document length and readability of SAR and annual reports (AR). We find that SAR are approximately 10 percent of the AR length and both have a ___very difficult___ readability score. We then use a disclosure index to examine the relation between SAR report length and the level of disclosures. After controlling for other factors that impact the level of disclosure, we conclude that the reduction in SAR is driven by lower levels of content. We then discuss the policy implications of our findings.

SummaryBackgroundIBD diagnosed after the age of 60 is increasing. Data on post‐operative complications in elderly onset IBD are scarce.AimTo describe the incidence of and factors associated with post‐operative complications in elderly onset IBD, diagnosed after the age of 60.MethodsUsing EPIMAD Cohort (1988‐2006), among 841 incident IBD patients, 139 (17%) underwent intestinal surgery, including 100 Crohn's disease (CD) and 39 ulcerative colitis (UC).ResultsAfter a median post‐operative follow‐up of 6 years (2‐10), 50 (36%) patients experienced at least 1 complication with a total of 69. During the first 30 post‐operative days, the mortality rate was 4%. Thirty‐two early complications (<30 days) were observed in 23 patients (17%), with 15 infectious, without significant difference between CD and UC. More than half early post‐operative complications (n = 19, 59%) were severe (>grade 2) without significant difference between CD and UC (P = 0.28). Thirty‐seven long‐term adverse effects of surgical therapy (≥30 days) were observed in 33 patients (24%). Multivariate analysis found (1) acute severe colitis (OR = 7.84 [2.15‐28.52]) and emergency surgery (OR = 4.46 [1.75‐11.36]) were associated with early post‐operative complications, and (2) Female gender (HR = 2.10 [1.01‐4.37]) and delay before surgery >3 months (HR = 2.09 [1.01‐4.31]) with long‐term adverse effects of surgical therapy.ConclusionsOne‐third of elderly IBD patients experienced at least 1 post‐operative complication. Half of the early complications were severe, and infectious. Emergency surgery was the key driver for post‐operative complication.
Scalable Bayesian Variable Selection for Structured High-Dimensional Data
Authors: Chang Changgee , Kundu Suprateek , Long Qi 
Published: May 2018

SummaryVariable selection for structured covariates lying on an underlying known graph is a problem motivated by practical applications, and has been a topic of increasing interest. However, most of the existing methods may not be scalable to high-dimensional settings involving tens of thousands of variables lying on known pathways such as the case in genomics studies. We propose an adaptive Bayesian shrinkage approach which incorporates prior network information by smoothing the shrinkage parameters for connected variables in the graph, so that the corresponding coefficients have a similar degree of shrinkage. We fit our model via a computationally efficient expectation maximization algorithm which scalable to high-dimensional settings (). Theoretical properties for fixed as well as increasing dimensions are established, even when the number of variables increases faster than the sample size. We demonstrate the advantages of our approach in terms of variable selection, prediction, and computational scalability via a simulation study, and apply the method to a cancer genomics study.
Promoting Replicability in Developmental Research Through Meta‐analyses: Insights From Language Acquisition Research
Authors: Bergmann Christina , Tsuji Sho , Piccinini Page E. , Lewis Molly L. , Braginsky Mika , Frank Michael C. , Cristia Alejandrina 
Published: May 2018

Previous work suggests that key factors for replicability, a necessary feature for theory building, include statistical power and appropriate research planning. These factors are examined by analyzing a collection of 12 standardized meta‐analyses on language development between birth and 5 years. With a median effect size of Cohen's d = .45 and typical sample size of 18 participants, most research is underpowered (range = 6%–99%; median = 44%); and calculating power based on seminal publications is not a suitable strategy. Method choice can be improved, as shown in analyses on exclusion rates and effect size as a function of method. The article ends with a discussion on how to increase replicability in both language acquisition studies specifically and developmental research more generally.
“It's our children!” Exploring intersectorial collaboration in family centres
Authors: Bulling Ingunn Skjesol , Berg Berit 
Published: May 2018

AbstractServices providing support for children and families are often described as fragmented and more concerned with the boundaries of their fields of responsibility than collaborating with other sectors. To meet the need for greater collaboration, there is increased impetus for establishing interdisciplinary services, such as family centres. This paper presents the results of a qualitative study based on in‐depth interviews and participant observation in 3 Norwegian family centres. The findings provide insight into central challenges in developing new practices within the field of family support; we discuss how intersectorial collaboration is constructed in relation to the core objectives of the family centre, professional competence, and service stability.This study demonstrates that both managers and professionals struggle with prioritizing intersectorial work, which mainly focuses on prevention and health promotion, over and above their traditional sectoral responsibilities. It also illustrates the necessity of articulating intersectorial collaboration as an explicit aim and exploring its implications and examining how this contributes to family centres building supportive communities. Building integrated services is not the ultimate goal of this particular form of service provision but rather the first step towards building interconnected support systems for all children in the community.
Social workers' views on community involvement in child protection work in Italy
Authors: Fazzi Luca 
Published: May 2018

AbstractInvolvement of the community is a topic that is gaining increasing importance in the debate on child protection social work. However, the empirical findings that help to understand the factors which enable social workers to involve community actors successfully are still scarce. The article presents the results of an empirical pilot study carried out on a sample of 24 child protection social workers employed in four public agencies in Italy. The results of the research highlight the complexity of the factors that influence the ability of social workers to involve the community in schemes involving children and their families and the importance of constructing a community‐based approach that directly involves local‐level institutions and policy programmes.
