What drives cloud ERP continuance? An integrated view
Authors: Cheng Yung-Ming 
Published: August 2018

PurposeThe purpose of this paper is to explore the key antecedents of organizational users’ continuance intention of cloud enterprise resource planning (ERP) by the integration of constructs from the expectation–confirmation model (ECM), technology acceptance model (TAM), theory of planned behavior (TPB), task-technology fit and TAM2.Design/methodology/approachSample data for this study were collected from end users of cloud ERP working in companies in Taiwan. A total of 560 questionnaires were distributed in the 56 sample companies, and 395 (70.5 percent) usable questionnaires were analyzed using structural equation modeling in this study.FindingsFindings show that while compatibility and output quality are key antecedents of confirmation of expectations toward cloud ERP, compatibility still reveals overwhelming and more indirect impacts on users’ continuance intention of cloud ERP than output quality because output quality has significant but evidently lesser effects on perceived usefulness and perceived ease of use than compatibility.Originality/valueFirst, this study contributes to the identification of compatibility and output quality that may reveal deep insights to the task-related factors in understanding users’ cloud ERP continuance greatly driven by their confirmation of expectations toward cloud ERP. Next, the empirical evidence on capturing the ECM, TAM and TPB for completely explaining the antecedents of users’ continued cloud ERP usage intention is well documented. Hence, this study’s findings have significantly shed light on the possible formulation of a richer post-adoption model.

Estimation of procurement costs incurred by public customers: a case study of a Russian region
Authors: Yakovlev Andrei , Balaeva Olga , Tkachenko Andrey 
Published: August 2018

Purpose
This paper aims to measure the cost of procurement because public procurement procedures prescribed by legislation not only enhance transparency and competition but also entail certain transaction costs for both customers and suppliers.

Design/methodology/approach
These costs are important to the efficiency of the procurement system. However, very few previous studies have focused on estimating procurement costs. This paper proposes a methodology for public procurement cost evaluation.

Findings
This paper shows how procurement costs can be calculated using a formalized survey of public customers. This methodology was tested with a representative group of public customers operating in one region of the Russian Federation.

Originality/value
The authors formulate the policy implications of this paper, as they relate to the improvement of public procurement regulations and argue that this methodological approach can be applied in other developing and transitioning economies.
Optimum formulation derivation for the ultimate packing fraction using monodispersed particle sizes when optimizing suspension viscosities
Authors: Sudduth Richard D. 
Published: August 2018

Purpose
The importance of maximizing the particle packing fraction in a suspension by maximizing average particle size ratio of D5/D1 has been adequately shown to be important as previously reported in the literature. This study aims to extend that analysis to include the best formulation approach to maximize the packing fraction with a minimum number of monodisperse particle sizes.

Design/methodology/approach
An existing model previously developed by this author was modified theoretically to optimize the ratio used between consecutive monodisperse particle sizes. This process was found to apply to a broad range of particle configurations and applications. In addition, five different approaches for maximizing average particle size ratio D̅5/D̅1 were addressed for blending several different particle size distributions. Maximizing average particle size ratio D̅5/D̅1 has been found to result in an optimization of the packing fraction. Several new concepts were also introduced in the process of maximizing the packing fraction for these different approaches.

Findings
The critical part of the analysis to maximize the packing fraction with a minimum number of particles was the theoretical optimization of the ratio used between consecutive monodisperse particle sizes. This analysis was also found to be effectively independent of the maximum starting particle size. This study also clarified the recent incorrect claim in the literature that Furnas in 1931 was the first to generate the maximum theoretical packing fraction possible for n different particles that was actually originally developed in conjunction with the Sudduth generalized viscosity equation. In addition, the Furnas generated equation was also shown to give significantly different results from the Sudduth generated equation.

Research limitations/implications
Experimental data involving monodisperse particles of different blends with a minimum number of particle sizes that are truly monodisperse are often extremely difficult to obtain. However, the theoretical general concepts can still be applicable.

Practical implications
The expanded model presented in this article provides practical guidelines for blending pigments using a minimum number of monodisperse particle sizes that can yield much higher ratios of the particle size averages D̅5/D̅1 and thus potentially achieve significantly improved properties such as viscosity.

Originality/value
The model presented in this article provides the first apparent guidelines to control the blending of pigments in coatings by the optimization of the ratio used between consecutive monodisperse particle sizes. This analysis was also found to be effectively independent of the maximum starting particle size.
Preparation of dye-grafted-silica/poly(acrylate) color coatings with enhanced color stability at elevated temperatures
Authors: Chang Chao-Ching , Huang Feng-Hsi , Cheng Liao-Ping 
Published: August 2018

Purpose
The purpose of this paper is to investigate the effects of dipentaerythritol hexaacrylate (DPHA) and 3-(trimethoxysilyl)propyl methacrylate-modified silica nanoparticles (MSiO2) contents on the performances of the Disperse Red 1 (DR1)-grafted-silica/poly(acrylate) color hard coatings.

Design/methodology/approach
The organic dye DR1 was silylated by reaction with the coupling agent 3-isocyanatopropyltriethoxysilane in methyl ethyl ketone. The silylated-DR1 thus obtained was grafted on MSiO2 to form dye-grafted silica (GSiO2). This hybrid dye was then UV-cured with the cross-linking agent, DPHA, to yield color coatings. Thermal durability of the coatings was evaluated based on their CIE (international commission on illumination) chromaticity coordinates and UV/Vis transmittances.

Findings
The results indicated that GSiO2-coatings could tolerate thermal attack better than pristine DR1-coatings or dye-absorbed silica (DSiO2)-coatings because of the fact that DR1 was more finely dispersed in the polymer binder when covalently bonded to the silica particles. Under optimal conditions, coatings with very small change of saturation and hue after high-temperature treatments were obtainable. These coatings appeared transparent, had 3H-6H pencil hardness and adhered perfectly onto the poly(methyl methacrylate) substrates.

Practical implications
Dye-grafted color coatings may find applications such as color filter photoresists for displays, microelectronics, printed circuit boards, etc.

Originality/value
The performances of the coatings were evaluated in terms of mechanical strength, adherence to the substrate, transmittance and color stability against heat treatments, which have not been disclosed. Also, using a newly developed triangular composition diagram, suitable ranges for preparing useful color coatings were accessed. The present method deserves further research studies on green and blue dyes.

Published: August 2018

PurposeThe purpose of this study is to improve the mechanical properties and reduce the stiffness/harshness of fabric associated with the pigment dyeing of textiles.Design/methodology/approachThe fabric was pigment dyed with the addition of three different softeners and binders. The fabric was then analyzed to have improved textile properties by measuring tear strength, bending length, crocking and washing fastness tests.FindingsThe conventional route of pigment dyeing (without any softener) imparted poor mechanical and rubbing fastness. The softener-added recipe provided better mechanical, rubbing and washing fastness, and the stiffness values were oppressed as well.Practical implicationsBecause of reduced stiffness, increased fastness and mechanical properties, the use of softener with pigment dyeing can improve the market values and satisfaction of the dyed fabrics. The finished product would also have better life and endurance. The process can be modified easily to have a better end-product with a negligible cost addition in industrial process, as softeners are cheap and used in low (10-20 g/l) in industrial settings without affecting the required shades.Originality/valueThis is the first report, to the best of the author’s knowledge, on the optimization of pigment dyeing of PC fabric with the addition of Helizarin and perapret softeners in dyeing bath.
Complete lymph node dissection or observation in melanoma patients with multiple positive sentinel lymph nodes: A single‐center retrospective analysis
Authors: Persa Oana‐Diana , Knuever Jana , Mauch Cornelia , Schlaak Max 
Published: August 2018

AbstractAlthough the role of sentinel lymph node biopsy (SLNB) as a prognostic factor is well established, its consequences for therapy are controversial. The aim of this study was to analyze if complete lymph node dissection (CLND) in patients with more than one positive sentinel lymph node (SLN) significantly improves melanoma‐specific survival (MSS) and progression‐free survival (PFS). Medical records of patients who underwent SLNB between 2001 and 2016 at the University Hospital of Cologne were reviewed, and patients with positive SLN were identified. Patient and tumor characteristics, patterns of recurrence, progression‐free and melanoma‐specific survival were analyzed. Seventy‐eight patients with multiple positive and 197 patients with one positive SLN were included in this study. Patients with multiple positive SLN had significantly more positive non‐SLN compared with patients with only one positive SLN (26.9% vs 8.6%, P = 0.01). However, in the subgroup of patients with multiple positive SLN, CLND did not significantly improve MSS (mean MSS 95 vs 75 months, P = 0.5) and PFS (mean PFS 59 vs 68 months P = 0.167). CLND did not result in a significant improvement in PFS and MSS in patients with multiple positive SLN.

Published: August 2018

SummaryTriplets of Lactobacullus plantarum strains were isolated from nine contrasting habitats. Without any passage through other culture media, isolation and cultivation were on model media that strictly reproduced the chemical and physical conditions and stressors of the habitats of origin. Here, we demonstrated how L. plantarum regulates and shapes its transcriptome in response to contrasting habitats. Firstly, multivariate clustering analysis of transcriptional data (RNA‐Seq), complemented with metabolomics and phenomics, grouped the strains according to the habitats of origin. Subsequently, selected strains from each habitat switched to repeated cultivation on MRS medium and transcriptomes homogenized into a unique cluster. Adaptation to this common medium mainly relied on activation of genes for phage‐ and prophage‐related proteins and transposases. Finally, the comparison of growth across model media and with respect to MRS medium showed that 44% of the overall 3112 gene transcripts changed depending on the specific habitat. Regulation and shaping of transcriptomes mainly concerned carbohydrate acquisition, pyruvate catabolism, proteolytic system and amino acid, lipid and inorganic ion transport and metabolism, with contrasting responses for contrasting habitats. Pathways reconstruction demonstrated how the large genome size of L. plantarum imparts transcriptome and metabolic flexibility as the basic mechanism for a nomadic lifestyle.

ObjectiveGrowing demand for VA dialysis exceeds its supply and travel distances prohibit many Veterans from receiving dialysis in a VA facility, leading to increased use of dialysis from non‐VA providers. This study compared utilization and hospitalization outcomes among Veterans receiving chronic dialysis in VA and non‐VA settings in 2008–2013.Data SourcesVA, Medicare, and national disease registry data.Study DesignNational cohort of 27,301 Veterans initiating dialysis, observed for a period of 2 years after treatment initiation. We used multinomial logistic regression to examine associations between patient characteristics and dialysis use in VA, non‐VA community settings via VA Purchased Care (VA‐PC), community settings via Medicare, or Dual settings. Zero‐inflated negative binomial regression was used to compare risk of hospitalization and days spent in the hospital across dialysis settings.Principal FindingsSixty‐seven percent of Veterans obtained community‐based dialysis exclusively via Medicare, 11 percent in the community via VA‐PC, 4 percent in VA, and 18 percent in Dual settings. Financial and geographic access factors were important predictors of dialysis setting, but days spent in the hospital and risk of hospitalization did not differ meaningfully across settings.ConclusionsMost Veterans obtained dialysis in the community. Dialysis setting appeared to have little impact on risk of hospitalization among Veterans.

Published: August 2018

AbstractAdult congenital heart disease (ACHD) patients are at risk for end‐stage heart failure; heart transplantation (Htx) represents the only definitive therapy available although not easily achievable for all patients. The study aims to assess the pathway difficulties and outcomes of ACHD patients with end‐stage heart failure referred for Htx evaluation. This is a single center retrospective study on ACHD patients with end‐stage heart failure referred to Htx evaluation from 2004 to 2015. Demographic data, medical history, failure modality, and follow‐up were obtained from patient charts. End‐points were Htx list enrollment, transplant, and survival. Statistical analysis was performed comparing patients listed and not listed. There were 21 ACHD patients with end‐stage heart failure referred to Htx evaluation. Transplant listing was declined for 12 (57%) meanwhile 9 patients were listed. Htx was successfully achieved in 3 patients after 24 and 36 months, respectively. Three patients are still on the wait list and three died while waiting, with a listed group mortality of 33.3% (3/9). Mortality occurred in first 18 months after Htx list enrollment. Not listed group mortality was 50% (6/12) and occurred after a median time of 17.5 months (IQR: 9–23 months). There was no difference in survival (P = 0.574) between listed and not listed (89, 63, and 63% vs. 83, 56, and 47% at 12–24–48 months). Follow‐up median duration was 27 months (IQR: 14–56 months). Heart transplant listing for ACHD patients with end‐stage heart failure is hard to obtain. Almost 2/3 of the patients were declined. Survival for these patients is reduced severely either in waiting list for transplant or excluded indicating the potential need of mechanical circulatory support as bridge to transplant or as destination therapy to improve survival likelihood.

Older (but not younger) preschoolers reject incorrect knowledge claims
Authors: Fedra Emmily , Schmidt Marco F. H. 
Published: August 2018

As epistemic and normative learners, children are dependent on their developing skills for evaluating others’ claims. This competence seems particularly important in the current digital age in which children need to discern valid from invalid assertions about the world in both real‐life and virtual interactions to ultimately gather and accumulate robust knowledge. We investigated whether younger and older preschoolers (N = 48) understand that a speaker's knowledge claim (‘I know where X is’) may be correct or incorrect given objectively accessible information (about whether the speaker had perceptual access to a critical event). We found that both younger and older preschoolers accepted correct knowledge claims that matched observable reality, but that only older preschoolers reliably rejected incorrect knowledge claims that did not match reality (the speaker lacked perceptual access). Nevertheless, a considerable proportion of younger preschoolers both rejected incorrect knowledge claims and gave valid explanations, suggesting that the ability to scrutinize epistemic claims develops gradually from around 3 to 4 years of age. These findings may help integrate research on children's norm and theory of mind development.
Statement of contribution

What is already known on this subject?

Preschoolers understand that non‐epistemic claims (e.g., ‘This is an X!’) may be correct or incorrect, and they track a speaker's relevant characteristics in testimonial situations.

It is not known what preschoolers understand about the validity of epistemic (knowledge) claims (e.g., ‘I know that X’).

What does this study add?

Younger and older preschoolers accepted correct knowledge claims (children observed that a speaker saw a critical event and was thus knowledgeable).

Only older preschoolers reliably rejected incorrect knowledge claims (the speaker did not see the critical event).

Nevertheless, a considerable proportion of younger preschoolers showed competence in their evaluation of, and reasoning about, incorrect knowledge claims.

Findings suggest that the ability to evaluate epistemic claims develops gradually from around 3 to 4 years of age.

SummaryMantle cell lymphoma (MCL) is still considered incurable and the course of the disease is highly variable. Established risk factors include the Mantle Cell Lymphoma International Prognostic Index (MIPI) and the quantification of the proliferation rate of the tumour cells, e.g. by Ki‐67 immunohistochemistry. In this study, we aimed to validate the prognostic value of the gene expression‐based MCL35 proliferation assay in patient cohorts from randomized trials of the European Mantle Cell Lymphoma Network. Using this assay, we analysed the gene expression proliferation signature in routine diagnostic lymph node specimens from MCL Younger and MCL Elderly trial patients, and the calculated MCL35 score was used to assign MCL patients to low (61%), standard (27%) or high (12%) risk groups with significantly different outcomes. We confirm here in our prospective clinical trial cohort of MCL patients, that the MCL35 assay is strongly prognostic, providing additional information to the Ki‐67 index and the MIPI. Thus, this robust assay may assist in making treatment decisions or in devising risk‐adapted prospective clinical trials in the future.
Inflammatory mediators: a causal link to hypertension during preeclampsia
Authors: Cornelius Denise C , Cottrell Jesse , Amaral Lorena M , LaMarca Babbette 
Published: August 2018

Preeclampsia (PE) is a hypertensive disorder that occurs after 20 weeks of gestation, implicating the placenta as a key offender. PE is associated with an imbalance among B lymphocytes, CD4+ T lymphocytes, NK cells and increased inflammatory cytokines. During early onset PE, trophoblast invasion and placentation are impaired, leading to reduced blood flow to the fetus. In all spectrums of this disorder, a shift towards a pro‐inflammatory state where regulatory cells and cytokines are decreased occurs. Specifically, inflammatory CD4+ T‐cells and inflammatory cytokines are increased while CD4+ T regulatory cells (Tregs) and immunosuppressive cytokines such as IL‐4 and IL‐10 are decreased resulting in B cell activation, production of autoantibodies, endothelial dysfunction and hypertension associated with PE. However, the stimulus for these imbalances is unknown and need to be fully understood so that effective treatments that target the pathogenesis of the disease can be designed. Therefore, this review will focus on the pathways involving CD4+, TH1, TH2, Tregs, TH17s, B cells, and NK cells in the pathophysiology of PE.Linked ArticlesThis article is part of a themed section on Immune Targets in Hypertension.
