Non-linear effects of relational capital on supply-side resilience
Authors: Fan Yiyi , Stevenson Mark 
Published: October 2019

PurposePrior studies have largely overlooked the potentially negative consequences of a buyer’s relational capital (RC) with a supplier for supply-side resilience, assuming a positive linear relationship between the constructs. Meanwhile, the focus of research has been at an organisational level without incorporating the role of boundary spanning individuals at the interface between buyer and supplier. Drawing on social capital and boundary spanning theory, the purpose of this paper is to: re-examine the relationship between RC and supply-side resilience, challenging the linear assumption; and investigate how both the strength and diversity of a boundary spanner’s ties moderate this relationship.Design/methodology/approachSurvey data are collected from 248 firms and validated using a subset of 57 attentive secondary respondents and archival data. The latent moderated structural equation method is applied to analyse the data.FindingsAn inverted U-shaped relationship between RC and supply-side resilience is identified. Tie strength in particular has a positive moderating effect on the relationship. More specifically, the downward RC–supply-side resilience relationship flips into an upward curvilinear relationship when boundary spanning individuals develop stronger ties with supplier personnel.Research limitations/implicationsA deeper insight into the RC–supply-side resilience relationship is provided. Findings are based on Chinese manufacturing firms and cross-sectional data meaning further research is needed to determine their generalisability.Practical implicationsIn evaluating how to enhance supply-side resilience, buying firms must decide whether the associated collaborative benefits of developing RC outweigh the potential costs. Managers also need to be concerned with the impact of developing RC between organisations and enhancing the tie strength of individuals simultaneously.Originality/valueThe paper goes beyond the linear relationship between RC and supply-side resilience. Incorporating the moderating role of boundary spanners identifies a novel phenomenon whereby the RC–resilience relationship flips from an inverted to a U-shaped curve.
Making sense of flipping data
Authors: Hart Simon , Nicholls Scott , Amos Howard , Benn Jill 
Published: October 2019

Purpose
The purpose of this paper is to detail the approach used in a project that worked with journal publication, subscription and article processing charges (APC) data. The project aim was to test if the resources allocated by the Matariki Network of Universities, a group of seven medium-sized universities, would pay for APC at the current level of publishing activity.

Design/methodology/approach
Data were collated and analysed from three years (2015–2017) for each of the seven partners.

Findings
A range of assumptions were made in dealing with the data. It was difficult to identify a subscription package that was common to all the partners. Data were not always consistent and in some instances it was incomplete. An iterative and flexible approach was required in this project. Even though testing had been carried out during planning, changes had to be made as the project was carried out. The timetable had to be flexible as those working on the project dealt with their day-to-day operational priorities and to enable each of the partners to contribute as resources allowed.

Practical implications
As alternative models of scholarly journal publication are evolving, it is important that the implications of these be tested to inform planning. Details of this testing need to be shared so that others can confirm the results, consider the approach and apply lessons learned.

Originality/value
This paper focuses on the details of the investigation so that others interested in repeating this project, or carrying out a similar project, can consider this in their planning.

Filling efficiency of flip-chip underfill encapsulation process
Authors: Ng Fei Chong , Abas Mohamad Aizat , Abdullah Mohd Zulkifly 
Published: October 2019

Purpose
This paper aims to introduce a new indicative parameter of filling efficiency to quantify the performance and productivity of the flip-chip underfill encapsulation process. Additionally, the variation effect of the bump pitch of flip-chip on the filling efficiency was demonstrated to provide insight for flip-chip design optimization.

Design/methodology/approach
The filling efficiency was formulated analytically based on the conceptual spatial and temporal perspectives. Subsequently, the effect of bump pitch on filling efficiency was studied based on the past actual-scaled and current scaled-up underfill experiments. The latter scaled-up experiment was validated with both the finite volume method-based numerical simulation and analytical filling time model. Moreover, the scaling validity of scaled-up experiment was justified based on the similarity analysis of dimensionless number.

Findings
Through the scaling analysis, the current scaled-up experimental system is justified to be valid since the adopted scaling factor 40 is less than the theoretical scaling limit of 270. Furthermore, the current experiment was qualitatively well validated with the numerical simulation and analytical filling time model. It is found that the filling efficiency increases with the bump pitch, such that doubling the bump pitch would triple the efficiency.

Practical implications
The new performance indicative index of filling efficiency enables the package designers to justify the variation effect of underfill parameter on the overall underfill process. Moreover, the upper limit of scaling factor for scaled-up package was derived to serve as the guideline for future scaled-up underfill experiments.

Originality/value
The performance of underfill process as highlighted in this paper was never being quantified before in the past literatures. Similarly, the scaling limit that is associated to the scaled-up underfill experiment was never being reported elsewhere too.
Optimisation of a guided endodontics protocol for removal of fibre‐reinforced posts
Authors: Perez Cyril , Finelle Gary , Couvrechel Cauris 
Published: October 2019

AbstractThis paper demonstrates the usefulness of endodontic guides for the removal of fibre posts. A 36‐year‐old man consulted for retreatment of a maxillary first molar presenting a periapical pathology. This tooth revealed a composite reconstruction together with a glass‐fibre post in the palatal root canal. To assist removal, use of an endodontic 3D‐printed guide was indicated. A cone beam computed tomography examination and an optical impression were made to produce a tooth‐supported guide by means of implant planning software (Blue Sky Plan, Blue Sky Bio®). The software enabled definition of a drilling pathway, which was transferred clinically using a resin template together with a sleeve and a 0.75‐mm drill. The drill was guided as far as the gutta‐percha situated in the apical third, limiting any risk of impairment or perforation.

AbstractObjectivesDysfunction of cognitive control is a feature of both bipolar disorder (BP) and major depression (MDD) and persists through to remission. However, it is unknown whether these disorders are characterized by common or distinct disruptions of cognitive control function and its neural basis. We investigated this gap in knowledge in asymptomatic BP and MDD participants, interpreted within a framework of normative function.MethodsParticipants underwent fMRI scans engaging cognitive control through a working memory task and completed a cognitive battery evaluating performance across multiple subdomains of cognitive control, including attention, impulsivity, processing speed, executive function, and memory. Analysis was performed in two stages: (i) cognitive control‐related brain activation and deactivation were correlated with cognitive control performance in 115 healthy controls (HCs), then, (ii) significantly correlated regions from (i) were compared between 25 asymptomatic BP, 25 remitted MDD, and with 25 different HCs, matched for age and gender.ResultsImpulsivity and executive function performance were significantly worse in BP compared to both MDD and HCs. Both BP and MDD had significantly poorer memory performance compared to HCs. Greater deactivation of the medial prefrontal cortex (MPFC) during the fMRI task was associated with better executive function in healthy controls. Significantly less deactivation in this region was present in both BP and MDD compared to HCs.ConclusionsFailure to deactivate the MPFC, a key region of the default mode network, during working memory processing is a shared neural feature present in both bipolar and major depression and could be a source of common cognitive dysfunction.

Published: October 2019

AbstractIn this study, we aimed to produce a coloured polyester fabric through the in situ sonosynthesis of copper nanoparticles using copper sulphate, hydrazine, sodium hydroxide and polyvinylpyrrolidone. The treated fabrics were characterised by X‐ray diffraction, field emission scanning electron microscopy, energy‐dispersive X‐ray spectroscopy and elemental mapping. Moreover, mechanical properties, wettability and antibacterial/antifungal activities of the treated fabrics were evaluated. Central composite design based on the response surface methodology was used to study the effect of copper sulphate, hydrazine hydrate and sodium hydroxide on the weight gain and colour of the treated fabrics. In addition to their roles as reducing agents, hydrazine and sodium hydroxide were responsible for the simultaneous aminolysis and hydrolysis of polyester, increasing the adsorption of nanoparticles on the surface. According to the results, the reddish brown samples treated with copper nanoparticles showed excellent antibacterial and antifungal efficiencies, improved tensile strength and decreased wettability.

Authors: Vénica Claudia I. , Spotti María J. , Pavón Yanina L. , Molli José S. , Perotti María C. 
Published: October 2019

SummaryThe incorporation of 1% (E1) and 2% (E2) of the carrot fibre powder obtained from carrot discards to yogurts was studied. The effect of the fibre addition on the physicochemical parameters, water‐holding capacity (WHC), microbial counts, rheological, microstructure and sensory characteristics of yogurts was studied in comparison with control yogurt without fibre addition (C). Titratable acidity, global composition and microbial counts showed a similar trend among yogurts. Fibre particles seemed to change the organisation of protein aggregates of the gel network. An open structure with bigger aggregates was observed in E1 and E2 yogurts, while the microstructure appeared more homogenous and without granules in C. However, carrot fibre increased the WHC of yogurt. All the yogurt samples exhibited shear‐thinning behaviour and no differences were found in the rheological parameters, excepting for E2 that presented a decrease in apparent viscosity at 200 s‐1 compared with C and E1 samples. Trained sensory panel (12 members) indicated an increase in brownish colour, strange flavour, grittiness and aftertaste and a decrease in overall appearance, odour, sweetness and creaminess in yogurts enriched in fibre. In order to mask these negative characteristics, E1 formulation was produced in the same way but strawberry flavour and colour were added. A consumer test (101 volunteers), purchase intention and a Check All That Apply (CATA) questionnaires were carried out. Flavoured and coloured E1 yogurt was pleasant for consumers, since 93% of the consumers selected positive degrees of acceptability and 68% of them manifested that they are willing to consume the product. Therefore, the addition of carrot fibre powder in yogurts could be an alternative to incorporate dietary fibres into dairy foods.
Enteral nutrition in critically ill adults: Literature review of protocols
Authors: Jordan Elizabeth A. , Moore Shelley C. 
Published: October 2019

AbstractBackgroundManaging nutrition in critically ill patients is an important intervention to promote healing. It is unknown whether the implementation of a protocol that guides enteral nutrition (EN) support is effective in improving the outcomes of critically ill patients. Furthermore, it is unknown whether a nurse‐driven protocol is more or less effective than a protocol not managed by nurses.Aims and objectivesThe purpose of this literature review is to determine the current state of the science regarding evidence‐based protocols for the administration and management of EN in critically ill patients.Search strategy, inclusion, and exclusion criteriaStudies were identified by searching the Cumulative Index to Nursing and Allied Health Literature Plus database for the terms “enteral nutrition AND nursing.” Studies with EN protocols for adult, critically ill patients published since 2011 were included. Studies without a protocol and those pertaining to paediatric, disease‐specific, medical‐surgical, or community‐based populations were excluded. A total of 10 studies meeting the inclusion criteria were identified.ConclusionsDefining and implementing both early initiation of EN and adequate titration to goal are important for achieving the maximum nutritional advantage. The highest benefit is also derived from identifying and delivering an individualized caloric and/or protein goal. A protocol increases standardization of practice in relation to these themes as well as the management of gastric residual volume, complications, and potentially for managing feeding interruptions. Because of the significant effects of nursing care on nearly all aspects of the management and delivery of EN, a nurse‐driven protocol may yield higher compliance and greater effectiveness than a protocol that is not nurse driven.Relevance to clinical practiceNurses are at the forefront of EN administration, although interprofessional collaboration remains paramount. Current practice must align with the best practice in the development and implementation of an EN protocol.
Distribution of Parthenium hysterophorus and one of its biological control agents (Coleoptera: Zygogramma bicolorata) in Nepal

Published: October 2019

SummaryParthenium hysterophorus is a noxious invasive weed of both agricultural and natural ecosystems, spreading aggressively in Nepal. Management of this weed in Nepal has been limited, mainly because of the lack of geo‐referenced data concerning the weed's distribution. We conducted a nationwide survey of P. hysterophorus and its coleopteran biological control agent Zygogramma bicolorata from 2013 to 2016 to determine their spatial distribution. Both were widespread, with the distribution of Z. bicolorata lagging behind the invasion front of P. hysterophorus. The weed was present in 21.2% of the 4838 locations examined, including several isolated satellite populations. The weed was found in the Tarai, Siwalik, Middle Mountains and High Mountains regions, reaching up to 2000 m asl. It has invaded natural and modified ecosystems including all six protected areas in the Tarai and Siwalik regions. Road access appears to be the major pathway for its long‐distance dispersal. Zygogramma bicolorata had spread from the east to the west and was present in 15.4% of the weed occurrence locations, inflicting a low amount of damage. A CLIMEX modelling projection revealed the presence of additional geographic areas in Nepal which are climatically suitable for both P. hysterophorus and Z. bicolorata. Eradication of satellite populations of the weed by physical and chemical measures, and the release of Z. bicolorata into new, but climatically suitable, locations should be prioritised for P. hysterophorus management in Nepal. In conclusion, P. hysterophorus has rapidly become widespread in Nepal and the currently available biological control agent has not been able to prevent further spread of the weed.
Lava lake thermal pattern classification using self-organizing maps and relationships to eruption processes at Kīlauea Volcano, Hawai‘i

ABSTRACT
Kīlauea Volcano’s active summit lava lake posed hazards to downwind residents and over 1.6 million Hawai‘i Volcanoes National Park visitors each year during 2008–2018. The lava lake surface was dynamic; crustal plates separated by incandescent cracks moved across the lake as magma circulated below. We hypothesize that these dynamic thermal patterns were related to changes in other volcanic processes, such that sequences of thermal images may provide information about eruption parameters that are sometimes difficult to measure. The ability to learn about concurrent gas emissions and seismic activity from a remote thermal time-lapse camera would be beneficial when conditions are too hazardous for field measurements. We applied a machine learning algorithm called self-organizing maps (SOM) to thermal infrared time-lapse images of the lava lake collected hourly over 23 April–21 October 2013 (n= 4354). The SOM algorithm can take thousands of seemingly different images, each representing the spatial distribution of relative temperature across the lava lake surface, and group them into clusters based on their similarities. We then related the resulting clusters to sulfur dioxide emissions and seismic tremor activity to characterizeties between the SOM classification and different emplacement conditions. The SOM classification results are highly sensitive to the normalization method applied to the input images. The standard pixel-by-pixel normalization method yields a cluster of images defined by the highest observed SO2 emission levels, elevated surface temperatures, and a high proportion of cracks between crustal plates. When lava lake surface patterns are isolated by minimizing the effect of temperature variation between images, relationships with seismic tremor activity emerge, revealing an “intense spatter” cluster, characterized by unstable, broken-up crustal plate patterns on the lava lake surface. This proof of concept study provides a basis for extending the SOM classification method to hazard forecasting and real-time volcanic monitoring applications, as well as comparative studies at other lava lakes.

Background/aimsThere is a paucity of large trials investigating the effect of management strategies for paediatric non-infectious uveitis on complications requiring surgery. The purpose of our study is to investigate whether earlier initiation of systemic immunosuppression in paediatric non-infectious uveitis is associated with fewer ophthalmic surgeries.MethodsA retrospective review was conducted on 48 children with non-infectious uveitis assessed in 1998–2013. Patients were divided into uveitis diagnosed before December 2008 (group 1) and after January 2009 (group 2). Duration from uveitis onset to methotrexate initiation (U-MTX) and biological addition (U-Biologic) were reviewed. Follow-up visits with topical corticosteroids >3 times daily and active uveitis (≥1+ cells) during 3.5 years were documented. The main outcome measure was the need for ≥1 ophthalmic surgery at 3.5 years.ResultsIn group 1, 69.5% of patients required ≥1 ophthalmic surgery at 3.5 years versus 26.9% in group 2 (p=0.005). U-MTX was 28.9±11.8 weeks and 14.2±10.0 weeks for groups 1 and 2 (p=0.028). U-Biologic was 134.6±46.0 weeks and 82.3±43.3 weeks for groups 1 and 2 (p=0.0016). Corticosteroid use >3 times daily was 85.9±52.7 weeks and 14.6±11.1 weeks for groups 1 and 2. Multivariate regression showed methotrexate initiation within 6 months of uveitis onset lowered the likelihood of needing ophthalmic surgery at 3.5 years (OR=6.2, 95% CI 1.2 to 33.4; p=0.033). Univariate regression demonstrated biological addition within 18 months of uveitis onset reduced the likelihood of requiring ophthalmic surgery (OR 12.57, 95% CI 1.28 to 123.48; p=0.030).ConclusionEarlier control of uveitis by addition of immunosuppressive therapy reduced the need for ophthalmic surgery.
Generalized Galileon scenario inspires chaotic inflation
Authors: López Matías , Maggiolo Jorge , Videla Nelson , González Pablo , Panotopoulos Grigoris 
Published: October 2019

Abstract
We study chaotic inflation with a Galileon-like self-interaction $$G(\phi ,X)\Box \phi $$G(ϕ,X)□ϕ, where $$G(\phi ,X)\propto X^{n}$$G(ϕ,X)∝Xn. General conditions required for successful inflation are deduced and discussed from the background and cosmological perturbations under slow-roll approximation. Interestingly, it is found that in the regime where the Galileon term dominates over the standard kinetic term, the tensor-to-scalar ratio becomes significantly suppressed in comparison to the standard expression in General Relativity (GR). Particularly, we find the allowed range in the space of parameters characterizing the chaotic quadratic and quartic inflation models by considering the current observational data of Planck from the $$n_{\mathcal {S}}-r$$nS-r plane. Finally, we discuss about the issue if the Galileon term is dominant by the end of inflation, this can affect the field oscillation during reheating.
