Short-range and tensor correlations in $^{4}$He and $^{8}$Be studied with the antisymmetrized quasi-cluster model
Authors: Itagaki N , Matsuno H , Kanada-En’yo Y 
Published: April 2019

Abstract
We apply the tensor version of the antisymmetrized quasi-cluster model (AQCM-T) to $^4\textrm{He}$ and $^8\textrm{Be}$ while focusing on the $NN$ correlations in $\alpha$ clusters. We adopt the $NN$ interactions including realistic ones containing a repulsive core for the central part in addition to the tensor part. In $^4\textrm{He}$, the $pn$ pair in the $^3D$ channel has been known to play a decisive role in the tensor correlation and the framework is capable of treating not only this channel but also the $NN$ correlations in the $^1S$ and $^3S$ channels. In $^8\textrm{Be}$, when two $\alpha$ clusters approach, the $^3D$ pair is suppressed because of the Pauli blocking effect, which also induces a decrease in the $^3S$ component through the $^3S$–$^3D$ coupling. These coherent effects result in the reduction of the attractive effect of the central-even interaction in the middle-range region and keep the distance between two $\alpha$ clusters.

Abstract

Background
A novel Mobile Medical Application (App) App was created on iOS platform (Neurology Dx®) to deduce Differential Diagnoses (DDx) from a set of user selected Symptoms, Signs, Imaging data and Lab findings. The DDx generated by the App was compared for diagnostic accuracy with differentials reasoned by participating neurology residents when presented with same clinical vignettes.

Methods
Hundred neurology residents in seven leading Neurology centers across India participated in this study. A panel of experts created 60 clinical vignettes of varying levels of difficulty related to Cognitive neurology. Each neurology resident was instructed to formulate DDx from a set of 15 cognitive neurology vignettes. Experts in Cognitive Neurology made the gold standard DDx answers to all 60 clinical vignettes. The differentials generated by the App and neurology residents were then compared with the Gold standard.

Results
Sixty clinical vignettes were tested on 100 neurology residents (15 vignettes each) and also on the App (60 vignettes). The frequency of gold standard high likely answers accurately documented by the residents was 25% compared with 65% by the App (95% CI 33.1–46.3), P &lt; 0.0001. Residents correctly identified the first high likely gold standard answer as their first high likely answer in 35% (95% CI 30.7–36.6) compared with 62% (95% CI 14.1–38.5), P &lt; 0.0001.

Conclusion
An App with adequate knowledge-base and appropriate algorithm can augment and complement human diagnostic reasoning in drawing a comprehensive list of DDx in the field of Cognitive Neurology (CTRI/2017/06/008838).
Co-reviewing and ghostwriting by early career researchers in the peer review of manuscripts

Published: April 2019

AbstractThe goal of this study is to shed light on the involvement of early career researchers (ECRs) during peer review of manuscripts for publication in journals. In particular, we sought to better understand how commonly ECRs contribute ideas and/or text to peer review reports when they are not the invited reviewer (“co-review”), and how commonly ECRs do not receive named credit to the journal editorial staff for these scholarly efforts (“ghostwrite”). First, we evaluated 1,952 publications in the peer-reviewed literature generated by exhaustive search terms that combined synonyms of “early career researcher” and “peer review” and found no previous studies about ECRs ghostwriting peer review reports. We then surveyed 498 researchers about their experiences with, and opinions about, co-reviewing and ghostwriting as ECRs. Three quarters of those surveyed have co-reviewed and most find it to be a beneficial (95% agree) and ethical (73% agree) form of training in peer review. Co-reviewing is the second most commonly reported form of training in peer review besides receiving reviews on one’s own papers. Half of survey respondents have ghostwritten a peer review report, despite the 4/5ths majority opinion that ghostwriting is unethical. Survey respondents report that the three major barriers to including co-reviewer names on peer review reports are: a lack of communication between PIs and ECRs; a false belief that co-authorship is for manuscripts but not peer review reports; and prohibitive journal policies that are out of alignment with current practice and opinions about best practice. We therefore propose recommendations for changing this status quo, to discourage unethical ghostwriting of peer review reports and encourage quality co-reviewing experiences as normal training in peer review.
Effect of inbreeding on type 2 diabetes-related metabolites in a Dutch genetic isolate

Published: April 2019

AbstractAutozygosity, meaning inheritance of an ancestral allele in the homozygous state is known to lead bi-allelic mutations that manifest their effects through the autosomal recessive inheritance pattern. Autosomal recessive mutations are known to be the underlying cause of several Mendelian metabolic diseases, especially among the offspring of related individuals. In line with this, inbreeding coefficient of an individual as a measure of cryptic autozygosity among the general population is known to lead adverse metabolic outcomes including type 2 diabetes (T2DM), a multifactorial metabolic disease for which the recessive genetic causes remain unknown. In order to unravel such effects for multiple metabolic facades of the disease, we investigated the relationship between the excess of homozygosity and the metabolic signature of T2DM. We included a set of heritable 143 circulating markers associated with fasting glucose in a Dutch genetic isolate Erasmus Rucphen Family (ERF) of up to 2,580 individuals. We calculated individual whole genome-based, exome-based and pedigree-based inbreeding coefficients and tested their influence on the T2DM-related metabolites as well as T2DM risk factors. We also performed model supervised genome-wide association analysis (GWAS) for the metabolites which significantly correlate with inbreeding values. Inbreeding value of the population significantly and positively correlated with associated with risk factors of T2DM: body-mass index (BMI), glucose, insulin resistance, fasting insulin and waist-hip ratio. We found that inbreeding influenced 32.9% of the T2DM-related metabolites, clustering among chemical groups of lipoproteins, amino-acids and phosphatidylcholines, whereas 80 % of these significant associations were independent of the BMI. The most remarkable effect of inbreeding is observed for S-HDL-ApoA1, for which we show evidence of the novelDISP1genetic region discovered by model supervised GWAS, in the ERF population. In conclusion, we show that inbreeding effects human metabolism and genetic models other than the globally used additive model is worth considering for study of metabolic phenotypes.
The continuing impact of an ancient polyploidy on the genomes of teleosts
Authors: Conant Gavin C. 
Published: April 2019

AbstractThe ancestor of most teleost fishes underwent a whole-genome duplication event three hundred million years ago. Despite its antiquity, the effects of this event are evident both in the structure of teleost genomes and in how those genes still operate to drive form and function. I describe the inference of a set of shared syntenic regions that survive from the teleost genome duplication (TGD) using eight teleost genomes and the outgroup gar genome (which lacks the TGD). I phylogenetically modeled the resolution of the TGD via shared and independent gene losses, concluding that it was likely an allopolyploidy event due to the biased pattern of these gene losses. Duplicate genes surviving from this duplication in zebrafish are less likely to function in early embryo development than are genes that have returned to single copy. As a result, surviving ohnologs function later in development, and the pattern of which tissues these ohnologs are expressed in and their functions lend support to recent suggestions that the TGD was the source of a morphological innovation in the structure of the teleost retina. Surviving duplicates also appear less likely to be essential than singletons, despite the fact that their single-copy orthologs in mouse are no less essential than other genes. Nonetheless, the surviving duplicates occupy central positions in the zebrafish metabolic network.
Cellular properties of intrinsically photosensitive retinal ganglion cells during postnatal development
Authors: Lucas Jasmine A. , Schmidt Tiffany M. 
Published: April 2019

AbstractBackgroundMelanopsin-expressing, intrinsically photosensitive retinal ganglion cells (ipRGCs) respond directly to light and have been shown to mediate a broad variety of visual behaviors in adult animals. ipRGCs are also the first light sensitive cells in the developing retina, and have been implicated in a number of retinal developmental processes such as pruning of retinal vasculature and refinement of retinofugal projections. However, little is currently known about the properties of the six ipRGC subtypes during development, and how these cells act to influence retinal development. We therefore sought to characterize the structure, physiology, and birthdate of the most abundant ipRGC subtypes, M1, M2, and M4, at discrete postnatal developmental timepoints.MethodsWe utilized whole cell patch clamp to measure the electrophysiological and morphological properties of ipRGC subtypes through postnatal development. We also used EdU labeling to determine the embryonic timepoints at which ipRGC subtypes terminally differentiate.ResultsOur data show that ipRGC subtypes are distinguishable from each other early in postnatal development. Additionally, we find that while ipRGC subtypes terminally differentiate at similar embryonic stages, the subtypes reach adult-like morphology and physiology at different developmental timepoints.ConclusionsThis work provides a broad assessment of ipRGC morphological and physiological properties during the postnatal stages at which they are most influential in modulating retinal development, and lays the groundwork for further understanding of the specific role of each ipRGC subtype in influencing retinal and visual system development.
Stability of Aβ-fibril fragments in the presence of fatty acids
Authors: Xi Wenhui , Vanderford Elliott K. , Liao Qinxin , Hansmann Ulrich H. E. 
Published: April 2019

AbstractWe consider the effect of lauric acid on the stability of various fibril-like assemblies of Aβ peptides. For this purpose, we have performed molecular dynamics simulations of these assemblies either in complex with lauric acid or without presence of the ligand. While we do not observe a stabilizing effect on Aβ40-fibrils we find that addition of lauric acid strengthen the stability of fibrils built from the more toxic triple-stranded S-shaped Aβ42-peptides. Or results may help to understand how specifics of the brain-environment modulate amyloid formation and propagation.
A systematic review of the literature on industrial divestment
Authors: Silva Pedro , Moreira Antonio Carrizo 
Published: April 2019

PurposeThe purpose of this paper is to review the existing research on industrial divestment in order to identify the reasons for it, the process whereby it is achieved, and the outcomes of industrial sell-offs and closures. The study reports the main findings that have gained acceptance in the literature, gaps in the research and potential directions for future research.Design/methodology/approachA three stage systematic literature review protocol was used to conduct this review. The results are organized according to an “Antecedents – Process – Outcomes” framework.FindingsThe traditional accounts of industrial divestment have been framed in terms of firms’ weak performance and over-diversification as antecedents to divestment, leading to corporate governance issues. However, the list of antecedents of industrial divestment is more extensive. There is no consensus over the impact of some factors on divestments, as is the case of firm and unit size. The results are not conclusive as to whether firm performance improves after divesting.Research limitations/implicationsFuture research should analyze the relationship between the antecedents of investment and divestment. The divestment process is not well studied and more studies that engage in theory building are needed, namely, on primary data and examining the short-term and long-term impacts of divestment on performance.Practical implicationsThis review offers a comprehensive synthesis of the antecedents, the process and outcomes of divestment through sell-offs and closures. Factors such as environmental conditions and the entry mode strategy are important in determining the divestment of subsidiaries. Divestments may be positively or negatively regarded by shareholders, depending on the context of the firm. Promoting managerial changes facilitates divestment.Originality/valueThis paper synthesizes knowledge of the main reasons as to why firms completely dispose of their assets, contributing to this under-researched field.
Hotel’s online reviews and ratings: a cross-cultural approach
Authors: Leon Ramona Diana 
Published: April 2019

Purpose
This paper aims to examine the impact of cultural specificity on hotel’s online reviews and ratings.

Design/methodology/approach
Using Hofstede’s scale of cultural differences, it analyzes 1,821 comments about the Catalonia Sagrada Familia Hotel across 77 countries. Logistic regression is used for data analysis.

Findings
It is found that detailed reviews tend to be provided by the guests who belong to a low-power distance culture, are collectivistic, are masculine, have a low uncertainty avoidance, are long-term orientated or are indulgent. On the other hand, the customers who tend to deviate from the prior average ratings come from high-power distance societies, are individualists, are feminists, belong to a high uncertainty avoidance culture, are long-term oriented or are indulgent.

Originality/value
These findings extend the hospitality management literature and potentially help the hotel managers to better understand their customers’ behavior in a web-based environment.
Strategic partner evaluation criteria for logistics service provider networks
Authors: Abidi Hella , Dullaert Wout , De Leeuw Sander , Lysko Darek , Klumpp Matthias 
Published: April 2019

PurposeThe purpose of this paper is to establish criteria for evaluating strategic partners in a network of logistics service providers (LSPs) to show how analytical network process (ANP) can be used to identify the weights of these criteria on a case-specific basis, and to investigate whether the ANP model can be used as a starting point to evaluate strategic partners for other LSP networks.Design/methodology/approachBased on a literature review of vertical cooperation, the authors develop an overview of criteria for the evaluation of partners in a network of LSPs. The authors then apply ANP at LSP1 to validate the criteria, identify weights for these criteria and to validate model outcomes. Furthermore, the authors investigate whether the ANP model developed for LSP1 can be applied to another LSP with similar characteristics (LSP2). In-depth interviews are used to draw conclusions on the modeling approach and the model outcomes.FindingsThe research shows that evaluation criteria for partners in vertical partnerships between shippers and LSPs are applicable to LSP partners in horizontal partnership networks. The ANP model with criteria weights provides a good starting point for LSPs to customize the evaluation framework according to their specific needs or operating environments.Originality/valueLimited research is available on evaluating LSP partners in horizontal partnerships. To the best of the authors’ knowledge, this paper is the first to bring forward horizontal LSP partner evaluation criteria to develop an ANP model for LSP partner evaluation and to apply this to two cases, and to provide a starting point for evaluating partners in similar horizontal LSP networks.
Modeling Deming’s quality principles to improve performance using interpretive structural modeling and MICMAC analysis
Authors: Agrawal Nishant Mukesh 
Published: April 2019

Purpose
The purpose of this paper is to study the 14 principles of Edwards Deming and create significant relationships between them. No research has been reported on the implementation of Total Quality Management (TQM) using Deming’s 14 principles. To fill this gap, Interpretive Structural Modeling (ISM) and MICMAC analysis have been developed to understand mutual interactions among variables and find both the dependence and driving power of these variables.

Design/methodology/approach
The research paper discusses a blend of practical applications and introduces a theoretical framework. An ISM-based methodology is used to study and examine interactions between identified variables, while MICMAC analysis is used to identify the dependence and driving power.

Findings
This research utilizes Deming’s 14 quality principles, with experts from academia and industry consulted to identify contextual relationships among variables. The result shows that the stated principles “take action to accomplish the transformation,” “institute training,” “encourage education to employees” and “institute leadership” are strategic requirements, while “drive out fear,” “break down barrier between staff areas” and “eliminate numerical quotas” are tactical requirements. “Adopt the new philosophy,” “create constancy in improvement of product and service” and “cease dependence on mass inspections” are operational requirements for TQM applications.

Originality/value
An ISM-based quality framework, dependence power and driving power of variables using MICMAC analysis have been recommended to the service and manufacturing industry as a new focus area in the implementation of TQM.
Constructing better health and wellbeing? Understanding structural constraints on promoting health and wellbeing in the UK construction industry
Authors: Hanna Esmée Sinéad , Markham Steven 
Published: April 2019

Purpose
The construction industry has high rates of work-related ill health. Whilst there have been more recent calls for a “health like safety” narrative within the industry, health has still predominantly been viewed via health risks rather than a more holistic conceptualisation of health and well-being. The workplace is viewed as a fruitful site for health promotion work, yet we know little about the possibilities and promise of health promotion within the construction industry. The paper aims to discuss these issues.

Design/methodology/approach
This paper explores the views of stakeholders with health-related roles and responsibilities within the UK construction industry. From the 21 semi-structured qualitative interviews, thematic analysis was conducted and two key themes emerged: the construction industry as anti-health promoting and understanding industry-specific health issues.

Findings
The construction industry faces significant constraint in attempting to promote better health and well-being due to its makeup, yet the health and well-being issues of the industry notably stress, and early retirement are major issues for both the industry and individuals.

Practical implications
The authors argue that only through understanding the structural constraints of the industry in this way can the possibilities and potentials for undertaking health promotion work be fully embedded within the industry in order to help create meaningful change for both employees and the industry as a whole.

Originality/value
This paper offers insight into the challenges that exist within construction for promoting positive employee health and well-being and takes an in-depth approach to exploring why health promotion may not be occurring within the industry.
Digital services governance: IT4IT™ for management of technology
Authors: Tambo Torben , Filtenborg Jacob 
Published: April 2019

Purpose
The purpose of this paper is to present, analyse and demonstrate the impact and potentials of a pragmatically derived information technology (IT) governance framework, IT4IT™, for the discipline of management of technology (MoT) especially within the IT industry.

Design/methodology/approach
This paper is based on an extensive literature study working with the limitations of the relatively recent publication of IT4IT™ and the normative character of IT4IT™. A mixed-method case study is presented based on an IT service provider organisation. Both a qualitative method and a systems and design oriented method are being used.

Findings
IT4IT™ can provide value and a clearer understanding of the service delivery framework if the technological core of the focal organisation is adapted to a value stream thinking. This suggests a more operational character of all IT processes and analogue to general MoT frameworks and corporate governance models.

Research limitations/implications
Given the recent publication of the IT4IT™ framework, this study is primarily ex ante and suggests further full-scale ex post research in the future.

Practical implications
Validation and successful implementation of the IT4IT™ framework will give companies better opportunities for safe and controlled value creation using IT. Control connects with risk reduction and less risk can encourage innovation and “tame” development complexity. Using value streams will align IT better with manufacturing and services.

Originality/value
Companies are striving to seek governance and risk minimisation in IT development and operations. This paper is discussing the applicability of the IT4IT™ framework for finding a better understanding of the value creation and value proposition delivered by introducing controlled processes minimising risk.
The learning experience continues: two decades and counting for CSULB’s SMIF program
Authors: Ammermann Peter , Gupta Pia , Ma Yulong 
Published: April 2019

Purpose
The student-managed investment fund (SMIF) program at California State University, Long Beach (CSULB), was launched in 1995 with one portfolio worth $50,000. In the two decades since then, the program has grown to include three portfolios with a combined value of more than $700,000, managed on behalf of three different clients. The purpose of this paper is to describe the creation, evolution and growth of the program including the development of the new quantitative approach and its subsequent implementation. The paper also discusses the ongoing organizational, educational and investment-management challenges associated with the program.

Design/methodology/approach
The paper includes a description of the development and evolution of the program along with a discussion of the investment results for one of its three portfolios.

Findings
The paper finds: the new quantitative approach implemented in the program is effective as insurance against “black swan” events; and SMIF-type programs can provide learning experiences both for students and faculty members.

Practical implications
The paper explains the practical application of the new quantitative approach as well as the educational benefits of a SMIF-type program.

Originality/value
The paper provides insight into the structure of CSULB’s SMIF program and discusses a unique quantitative approach to asset allocation and security selection.
