ABSTRACTCell-free DNA (cfDNA) in blood, urine and other biofluids provides a unique window into human health. A proportion of cfDNA is derived from bacteria and viruses, creating opportunities for the diagnosis of infection via metagenomic sequencing. The total biomass of microbial-derived cfDNA in clinical isolates is low, which makes metagenomic cfDNA sequencing susceptible to contamination and alignment noise. Here, we report Low Biomass Background Correction (LBBC), a bioinformatics noise filtering tool informed by the uniformity of the coverage of microbial genomes and the batch variation in the absolute abundance of microbial cfDNA. We demonstrate that LBBC leads to a dramatic reduction in false positive rate while minimally affecting the true positive rate for a cfDNA test to screen for urinary tract infection. We next performed high throughput sequencing of cfDNA in amniotic fluid collected from term uncomplicated pregnancies or those complicated with clinical chorioamnionitis with and without intra-amniotic infection. The data provide unique insight into the properties of fetal and maternal cfDNA in amniotic fluid, demonstrate the utility of cfDNA to screen for intra-amniotic infection, support the view that the amniotic fluid is sterile during normal pregnancy, and reveal cases of intra-amniotic inflammation without infection at term.

Published: August 2019

PurposeThe purpose of this paper is to investigate the extent to which firms in the Sri Lankan apparel industry practice supply-chain-resilience (SCRes) capabilities and examine whether SCRes practices affect the performance and competitive advantage of those firms.Design/methodology/approachUses a conceptual framework to assess SCRes capabilities and to investigate their impact on firm performance and competitive advantage. Uses partial least squares structural equation modeling (PLS-SEM) to quantitatively analyze questionnaire data collected from 89 Sri Lankan apparel manufacturers.FindingsIn the presence of SCRes capabilities in the apparel industry, this study finds that supply-chain risk-management culture positively affects SCRes capabilities, namely re-engineering, agility and collaboration. Agility shows the greatest influence on firm performance and competitive advantage.Research limitations/implicationsThis study is limited to the apparel industry sector (a manufacturing sector) in Sri Lanka to maintain the uniformity of the research constructs.Practical implicationsResults imply that management should pay more attention to enhancing SCRMC and prioritizing their SCRes capabilities.Originality/valueThis study is the first to assess SCRes capabilities in the apparel-manufacturing sector and examine the impact of SCRes capabilities on firm performance and competitive advantage.
Cornwall Foundation Trust’s capacity to implement the government’s children and young people’s mental health strategy
Authors: Macpherson Reynold , Vann Barbara 
Published: August 2019

Purpose
The purpose of this paper evaluates the capacity of the Cornwall Foundation Trust (CFT) of the National Health Service (NHS) to implement the UK Government’s children and young people’s mental health strategy through its school-based integrated health centre (SBIHC) delivery model.

Design/methodology/approach
This evaluation uses six case studies of SBIHCs to indicate the general effectiveness of this delivery model and its capacity to implement the three core proposals of the Government’s strategy. The core proposals are: to encourage all schools and colleges to identify and train a designated senior lead (DSL) for mental health; to fund new mental health support teams (MHSTs); and to develop strategies to meet the proposed four-week waiting time for access to specialist NHS mental health services.

Findings
This evaluation found that the Duchy Health Charity and CFT piloted a new delivery model in three SBIHCs from 2009 that successfully integrated health and educational services to children and adolescents, including general health and well-being and sexual and mental health and, more recently, integrated welfare services.

Research limitations/implications
The main research implication is that longitudinal case studies of organisational innovations can reveal the subtleties of educational management in context and potentially inform advances elsewhere consistent with national policy developments.

Practical implications
The main practical implication is that the SBIHCs at Penair Community School, Budehaven Community School, Hayle Community School, Looe Community Academy, Treviglas Community Academy and Wadebridge Community School should each be recognised as a “trailblazer site” in the implementation of the Government’s children and young people’s mental health strategy.

Social implications
Mandatory secondary education is the last opportunity that the UK society has to embed knowledge, skills and attitudes needed for the life-long self-management of health. The CFT’s SBIHC model trialled since 2009 has successfully integrated health and educational services to children and adolescents, including general health and well-being and sexual and mental health and, more recently, integrated welfare services.

Originality/value
This evaluation research is unique. It reports that the CFT’s SBIHC model is the first and only organisational innovation at a system level in the UK that has successfully integrated health and education services to children and adolescents.
The road already traveled: communication advice for higher education leaders
Authors: McNaughtan Jon L. , DePue Brooke Wilson , McNaughtan Elisabeth D. 
Published: August 2019

Purpose
Turnover of presidents in colleges and universities occurs frequently and new presidents are rarely trained to handle communication with the range of stakeholders involved in a campus community, which is one of the most complex tasks their job requires. New presidents need guidance and insight to prepare them for this vital aspect of campus leadership. The paper aims to discuss this issue.

Design/methodology/approach
This paper analyzes interviews with sitting presidents and vice presidents of communication at flagship universities in the USA to identify themes and best practices for presidential communication.

Findings
Analysis of interviews resulted in five consistent recommended practices: be informed about your issue and audience; utilize multiple communication channels; know when to speak; identify and use a communication team; and when you speak, use your own authentic voice.

Originality/value
Limited research exists on the communication process and skills needed to effectively lead colleges and universities. While incoming presidents often lack backgrounds and training in communication strategies, such strategies are required to effectively engage both internal and external audiences. The study provides new leaders with tips from seasoned leaders to enhance their communication strategies.

Purpose
The purpose of this paper is to explore undergraduate international students’ experiences in a flipped classroom environment in an Australian university.

Design/methodology/approach
In total, 32 in-depth interviews were conducted with undergraduate international students at one Australian university by three researchers.

Findings
The learning experiences of international students in a flipped classroom environment include increased flexibility in learning; enhanced engagement with content and; more confident participation in face-to-face workshops. In addition, the analysis further illustrates that international students intrinsically develop soft skills (e.g. increased confidence and communication skills), learning skills (e.g. research and critical thinking) and employability skills (e.g. time management and accountability).

Research limitations/implications
These findings focus only on the positive learning experiences of undergraduate international students in one Australian university.

Originality/value
The study contributes to the literature by identifying learning experiences of undergraduate international students in a flipped classroom environment and the connection with their development of soft skills, learning skills and employability skills.
Using probability impact matrix (PIM) in analyzing risk factors affecting the success of oil and gas construction projects in Yemen
Authors: A. Kassem Mukhtar , Khoiry Muhamad Azry , Hamzah Noraini 
Published: August 2019

Purpose
This study aims to identify and assess the significant risks in Yemen oil and gas construction projects based on their risk rating (impact and probability) by using probability–impact matrix (PIM).

Design/methodology/approach
In total, 51 risk factors that might affect construction projects in the oil and gas sector are defined through a detailed literature review and expert judgment. The risk factors were tabulated in a questionnaire form, which was sent to a total of 400 participants asking their contribution in identifying the risk matrix for the risk factors in terms of impact and probability of occurrence during the project life cycle. Five zones were used in the matrix according to the degree of risk factor’s severity on the success of the project. These zones are light green, dark green, yellow, light red and dark red.

Findings
The PIM analysis for risk factors found that five factors are located in the dark red zone, as top risks factors have a very high impact and very high probability of occurring; 40 factors are located in the light red zone; six factors are located in the yellow zone; and no factors are located in the green zone (light and dark), which is considered an indication of the importance of risk factors under study and their impact on the success of construction projects in the oil and gas sector. Moreover, the factors under feasibility study and design and resources and material; are the most categories effect on project success.

Research limitations/implications
The research was limited to the oil and gas construction projects in Yemen.

Practical implications
Practically, this study highlights the top risk factors in oil and gas construction projects, which might cause an adverse effect on project success in Yemen. Classification and ranking of these factors by using the risk matrix provide the basis for risk response planning to enhance the chances of project success.

Originality/value
This paper identifies the matrix for risk factors affecting the success of construction projects in the oil and gas industry in Yemen. There is a significant contribution expected from this research, especially for companies operating in the oil and gas sector and other organizations that plan to invest in this field, in addition to expected benefits for the Yemeni Government and researchers because of lack of research in this area.
An innovative medical consultation model in mainland China
Authors: Xu Xiao Ping , Ke Dong Ge , Deng Dong Ning , Houser Shannon H. , Li Xiao Ning , Wang Qing , Shan Ng Chui 
Published: August 2019

Purpose
The purposes of this paper are two-fold: first, to introduce a new concept of primary care consultation system at a mainland Chinese hospital in response to healthcare reform; and second, to explore the factors associated with change resistance and acceptance from both patients’ and medical staff’s perspectives.

Design/methodology/approach
A survey design study, with two questionnaires developed and distributed to patients and medical staff. Convenience and stratified random sampling methods were applied to patient and medical staff samples.

Findings
A 5-dimension, 21-item patient questionnaire and a 4-dimension, 16-item staff questionnaire were identified and confirmed, with 1020 patients (91.07 percent) and 202 staff (90.18 percent) as effective survey participants. The results revealed that patient resistance mainly stems from a lack of personal experiences with visiting general practice (GP) and being educated or having lived overseas; while staff resistance came from occupation, education, GP training certificate, and knowledge and experience with specialists. Living in overseas and knowledge of GP concepts, gender and education are associated with resistance of accepting the new practice model for both patients and staff.

Originality/value
There are few Chinese studies on process reengineering in the medical sector; this is the first study to adopt this medical consultation model and change in patients’ consultation culture in Mainland China. Applying organizational change and process reengineering theories to medical and healthcare services not only extends and expands hospital management theory but also allows investigation of modern hospital management practice. The experience from this study can serve as a reference to promote this new consultation model in Chinese healthcare reform.
Building supply-side resilience – a behavioural view
Authors: Vanpoucke Evelyne , Ellis Scott C. 
Published: August 2019

PurposeTo build resilient supply chains, buyers should implement risk mitigation tactics. The purpose of this paper is to provide insights into the risky decision-making process that underlies buyers’ decisions to adopt supply risk mitigation tactics for creating supply-side resilience.Design/methodology/approachThe authors employ experimental scenarios to simulate supply disruptions of low and high likelihood. The authors then assess buyers’ decisions to adopt supply risk mitigation tactics in response to these scenarios.FindingsThe authors find that buyers’ perceptions of supply disruption likelihood are positively related to their adoption of buffer- and process-oriented risk mitigation tactics and preference for process-oriented risk mitigation tactics. Conversely, risk propensity negatively affects buyers’ adoption of buffer- and process-oriented mitigation tactics.Originality/valueBeyond risk perceptions, the authors consider how risk propensity also affects the risky decision-making process. Moreover, whereas previous studies often focus on a single mitigation tactic, the authors study buyers’ adoption of multiple buffer- and process-oriented risk mitigation tactics to create supply-side resilience.
From the sharing economy to the visitor economy: the impact on small retailers
Authors: Grimmer Louise , Vorobjovas-Pinta Oskaras 
Published: August 2019

Purpose
The visitor economy is increasingly being recognised by local authorities, governments and destination marketing managers as having a significant effect on local retail precincts. This research note proposes that there is a link between the rise of the sharing economy (notably Airbnb) and the growing awareness and appreciation of the impact of the visitor economy. The purpose of this paper is to provide an example of the marketing efforts of a specific retail precinct to attract visitors engaged in the sharing economy.

Design/methodology/approach
The approach taken involves a review of the literature pertaining to the sharing and visitor economies. Using an example from an Australian tourist city – Hobart, Tasmania, this research reviews a collaborative marketing campaign undertaken by retailers in a city precinct designed to appeal to stakeholders in the visitor economy.

Findings
Shopping at local stores and retail precincts form an integral part of the travel experience. This research note offers an overview of the nexus between the sharing and visitor economies. In particular, it presents the potential implications of collaborative marketing efforts to attract visitors to a retail precinct. It is suggested that the development of new marketing and branding strategies, specifically retailer-led collaborative efforts, are a positive approach to attract stakeholders involved in the sharing and visitor economies.

Originality/value
This research note is one of the first to recognise the relationship between the rise of the sharing economy and the subsequent conceptualisation of a visitor economy. This note recognises the particular importance of the nexus between the sharing and visitor economies for retail precincts.

Authors: Biswas Siddhartha 
Published: August 2019

Purpose
The purpose of this paper is to deal with the three-dimensional analysis of free vibrations in a stress-free and rigidly fixed homogeneous transversely isotropic hollow cylinder in the context of three-phase-lag (TPL) model of hyperbolic thermoelasticity.

Design/methodology/approach
The matrix Frobenius method of extended power series is employed to obtain the solution of coupled ordinary differential equations along the radial coordinate.

Findings
The natural frequency, dissipation factor and inverse quality factor in the stress-free and rigidly fixed hollow cylinder get significantly affected due to thermal vibrations and thermo-mechanical coupling.

Originality/value
The modified Bessel functions and matrix Frobenius method have been directly used to study the vibration model of a homogeneous, transversely isotropic hollow cylinder in the context of TPL model based on three-dimensional thermoelasticity.

Authors: Casagranda Milena , Zanella Priscila Berti , Vieira Alexandra Ferreira , Macedo Rodrigo Cauduro Oliveira 
Published: August 2019

Purpose
The purpose of the study was to evaluate the acute effect of milk proteins supplementation, compared to another nitrogen compound on muscle protein synthesis.

Design/methodology/approach
The search was conducted on MEDLINE® (via PUBMED®), Cochrane and Embase databases, using the terms “whey proteins,” “caseins,” “milk proteins,” “protein biosynthesis,” “human” and its related entry terms. The selected outcome was fractional synthetic rate (FSR) before (0) and 3 h after consumption of milk proteins, compared to supplementation with other protein sources or isolated amino acids.

Findings
The results were expressed as mean difference (MD) of absolute values between treatments with confidence interval (CI) of 95 per cent. Of the 1,913 identified studies, 4 were included, with a total of 74 participants. Milk proteins generated a greater FSR (MD 0.03 per cent/h, CI 95 per cent 0.02-0.04; p < 0.00001), compared to control group. Acute consumption of milk proteins promotes higher increase in FSR than other protein sources or isolated amino acids.

Originality/value
This paper is a systematic review of the effects of milk proteins supplementation, which is considered an important subject because of its large consumption among athletes and physical exercise practitioners.
Towards a predictive framework for biocrust mediation of plant performance: A meta‐analysis

Abstract

Understanding the importance of biotic interactions in driving the distribution and abundance of species is a central goal of plant ecology. Early vascular plants likely colonized land occupied by biocrusts — photoautotrophic, surface‐dwelling soil communities comprised of cyanobacteria, bryophytes, lichens and fungi — suggesting biotic interactions between biocrusts and plants have been at play for some 2,000 million years. Today, biocrusts coexist with plants in dryland ecosystems worldwide, and have been shown to both facilitate or inhibit plant species performance depending on ecological context. Yet, the factors that drive the direction and magnitude of these effects remain largely unknown.

We conducted a meta‐analysis of plant responses to biocrusts using a global dataset encompassing 1,004 studies from six continents.

Meta‐analysis revealed there is no simple positive or negative effect of biocrusts on plants. Rather, plant responses differ by biocrust composition and plant species traits and vary across plant ontogeny. Moss‐dominated biocrusts facilitated, while lichen‐dominated biocrusts inhibited overall plant performance. Plant responses also varied among plant functional groups: C4 grasses received greater benefits from biocrusts compared to C3 grasses, and plants without N‐fixing symbionts responded more positively to biocrusts than plants with N‐fixing symbionts. Biocrusts decreased germination but facilitated growth of non‐native plant species.

Synthesis. Results suggest that interspecific variation in plant responses to biocrusts, contingent on biocrust type, plant traits, and ontogeny can have strong impacts on plant species performance. These findings have important implications for understanding biocrust contributions to plant productivity and community assembly processes in ecosystems worldwide.

Uterine transplantation restores reproductive anatomy in women with absolute uterine factor infertility and allows the opportunity to conceive, experience gestation, and acquire motherhood. The number of cases being performed is increasing exponentially, with detailed outcomes from 45 cases, including nine live births, now available. In light of the data presented herein, including detailed surgical, immunosuppressive and obstetric outcomes, the feasibility of uterine transplantation is now difficult to refute. However, it is associated with significant risk with more than one‐quarter of grafts removed because of complications, and one in ten donors suffering complications requiring surgical repair.Tweetable abstractUterine transplantation is feasible in women with uterine factor infertility, but is associated with significant risk of complication.
