Authors: Li Zhi , Zhu Andan , Song Qingxin , Chen Helen Y. , Harmon Frank G. , Chen Z. Jeffrey 
Published: October 2020

Abstract
Heterosis or hybrid vigor is widespread in plants and animals. Although the molecular basis for heterosis has been extensively studied, metabolic and proteomic contributions to heterosis remain elusive. Here we report an integrative analysis of time-series metabolome and proteome data in maize (Zea mays) hybrids and their inbred parents. Many maize metabolites and proteins are diurnally regulated, and many of these show nonadditive abundance in the hybrids, including key enzymes and metabolites involved in carbon assimilation. Compared with robust trait heterosis, metabolic heterosis is relatively mild. Interestingly, most amino acids display negative mid-parent heterosis (MPH), i.e., having lower values than the average of the parents, while sugars, alcohols, and nucleoside metabolites show positive MPH. From the network perspective, metabolites in the photosynthetic pathway show positive MPH, whereas metabolites in the photorespiratory pathway show negative MPH, which corresponds to nonadditive protein abundance and enzyme activities of key enzymes in the respective pathways in the hybrids. Moreover, diurnally expressed proteins that are upregulated in the hybrids are enriched in photosynthesis-related gene-ontology terms. Hybrids may more effectively remove toxic metabolites generated during photorespiration, and thus maintain higher photosynthetic efficiency. These metabolic and proteomic resources provide unique insight into heterosis and its utilization for high yielding maize and other crop plants.
Multiple logics within the international Islamic financial architecture: implications for Islamic financial reporting standards
Authors: Mukhlisin Murniati , Fadzly Mohamed 
Published: October 2020

PurposeThis paper aims to examine the existence of multiple institutional logics among a number of organisations within the international Islamic financial architecture (IIFA) whose main purpose is to promote and support the development of Islamic financial institutions (IFIs) across the globe and how IIFA relates to the role of Islamic financial reporting standards.Design/methodology/approachThe authors review websites of 11 IIFA’s constituent organisations and undertake 7 in-depth, semi-structured interviews with senior members of a selection of these organisations to identify the dominant logics by which their role and (inter)action within the IIFA are shaped.FindingsThe study findings reveal evidence of competing (and shifting) logics and political interests that seem to have led to contradictions and inconsistencies among the constituent organisations. The authors explain this by proposing a framework consisting of religion logic, market logic and corporate logic that intertwines with the underlying economic system and acts as sources of identity–legitimacy–authority for the respective organisations.Originality/valueThe authors bring to light some key issues that may pose a threat to the sustained existence of IFIs. The authors adapt the institutional logic framework and incorporate it into religion logic within the context of Islam (i.e. hifdzul-din as the first Maqasid ul-Shari’ah), resulting in some fresh theoretical perspective that may inform future research.
Motor imagery-based EEG signals classification by combining temporal and spatial deep characteristics
Authors: Xiaoling Li 
Published: October 2020

PurposeIn order to improve the weak recognition accuracy and robustness of the classification algorithm for brain-computer interface (BCI), this paper proposed a novel classification algorithm for motor imagery based on temporal and spatial characteristics extracted by using convolutional neural networks (TS-CNN) model.Design/methodology/approachAccording to the proposed algorithm, a five-layer neural network model was constructed to classify the electroencephalogram (EEG) signals. Firstly, the author designed a motor imagery-based BCI experiment, and four subjects were recruited to participate in the experiment for the recording of EEG signals. Then, after the EEG signals were preprocessed, the temporal and spatial characteristics of EEG signals were extracted by longitudinal convolutional kernel and transverse convolutional kernels, respectively. Finally, the classification of motor imagery was completed by using two fully connected layers.FindingsTo validate the classification performance and efficiency of the proposed algorithm, the comparative experiments with the state-of-the-arts algorithms are applied to validate the proposed algorithm. Experimental results have shown that the proposed TS-CNN model has the best performance and efficiency in the classification of motor imagery, reflecting on the introduced accuracy, precision, recall, ROC curve and F-score indexes.Originality/valueThe proposed TS-CNN model accurately recognized the EEG signals for different tasks of motor imagery, and provided theoretical basis and technical support for the application of BCI control system in the field of rehabilitation exoskeleton.

Published: October 2020

PurposeThis paper investigates the dependence structure and market risk of the currency exchange rate portfolio from the Malaysian ringgit perspective.Design/methodology/approachThe marginal return of the five major exchange rates series, i.e. United States dollar (USD), Japanese yen (JPY), Singapore dollar (SGD), Thai baht (THB) and Chinese Yuan Renminbi (CNY) are modelled by the Bayesian generalized autoregressive conditional heteroskedasticity (GARCH) (1,1) model with Student's t innovations. In addition, five different copulas, such as Gumbel, Clayton, Frank, Gaussian and Student's t, are applied for modelling the joint distribution for examining the dependence structure of the five currencies. Moreover, the portfolio risk is measured by Value at Risk (VaR) that considers the extreme events through the extreme value theory (EVT).FindingsThe finding shows that Gumbel and Student's t are the best-fitted Archimedean and elliptical copulas, for the five currencies. The dependence structure is asymmetric and heavy tailed.Research limitations/implicationsThe findings of this paper have important implications for diversification decision and hedging problems for investors who involving in foreign currencies. The authors found that the portfolio is diversified with the consideration of extreme events. Therefore, investors who are holding an individual currency with VaR higher than the portfolio may consider adding other currencies used in this paper for hedging.Originality/valueThis is the first paper estimating VaR of a currency exchange rate portfolio using a combination of Bayesian GARCH model, EVT and copula theory. Moreover, the VaR of the currency exchange rate portfolio can be used as a benchmark of the currency exchange market risk.

Published: October 2020

PurposePredictive analytics and artificial intelligence are perceived as significant drivers to improve organizational performance and managerial decision-making. Hiring employees and contract renewals are instances of managerial decision-making problems that can incur high financial costs and long-term impacts on organizational performance. The primary goal of this study is to identify the Major League Baseball (MLB) free agents who are likely to receive a contract.Design/methodology/approachThis study used the design science research paradigm and the cognitive analytics management (CAM) theory to develop the research framework. A dataset on MLB's free agents between 2013 and 2017 was collected. A decision support tool was built using artificial neural networks.FindingsThere are clear links between a player's statistical performance and the decision of the player to sign a new offered contract. “Age,” “Wins above Replacement” and “the team on which a player last played” are the most significant factors in determining if a player signs a new contract.Originality/valueThis paper applied analytical modeling to personnel decision-making using the design science paradigm and guided by CAM as the kernel theory. The study employed machine learning techniques, producing a model that predicts the probability of free agents signing a new contract. Also, a web-based tool was developed to help decision-makers in baseball front offices so they can determine which available free agents to offer contracts.
Knowledge management as a driver of performance in ambulatory healthcare – a systematic literature review through an intellectual capital lens
Authors: Pflugfelder Nina S. 
Published: October 2020

PurposeThe purpose of this study is to investigate how Knowledge Management (KM) and Intellectual Capital (IC) can increase the organizational performance of ambulatory healthcare providers and how such performance can be assessed.Design/methodology/approachFollowing the PRISMA guidelines, a structured review of peer-reviewed English-speaking articles up to 31stDecember 2019 was conducted. A search of ACM Digital Library, Cochrane Library, DARE, EBSCOHost, Medline, ProQuest, PubMed, ScienceDirect, Scopus and Web of Science produced 8,391 results. All studies that did not examine the impact of KM initiatives on organizational performance in an ambulatory healthcare provider setting were eliminated. The final sample of 31 studies was examined regarding the design of the KM initiatives as well as the performance concepts and indicators employed.FindingsA range of KM tools and methods (Electronic Health Records, Clinical Decision Support, Health Information Technology, Training, Communities of Practice) have been shown to improve healthcare processes but evidence of an impact on outcomes remains mixed. Performance indicators focus on medical quality but rarely capture economic or social performance. Indicators have been adapted from the medical field, but do not adequately capture IC and KM-induced performance.Originality/valueThis review provides an overview of KM initiatives in ambulatory healthcare and assesses the associated performance metrics through an IC lens. Thereby, it enables further research on the interplay of IC, KM and performance in ambulatory care and points to several research gaps. It provides managers with guidance for designing KM initiatives in their organizations
Hybrid intelligent vehicle system for managing construction supply chain in precast concrete building construction projects
Authors: Ismail Zul-Atfi Bin 
Published: October 2020

Purpose
While the adversarial nature of precast concrete (PC) building construction is frequently cited in the PC building construction press, only a few researchers have investigated construction supply chain management within the construction industry. Due to the interdisciplinary transportation environment, which inevitably results in disruption, the uses of construction supply chain and recovery from construction supply chain risk must be a subject of real interest, yet transportation management research in this area is scarce.

Design/methodology/approach
The purpose of this study is to discuss the weakness in system approaches and their application for managing precast concrete building in the context of construction supply chain practice and how to overcome it. As a precursor to this paper, the paper reviews current construction supply chain management occurrence on PC building construction and explores the hybrid intelligent vehicle tools and techniques currently being used on such management. This paper also presents the new hybrid intelligent vehicle-based approach to manage construction supply chain risk and reduce associated tension on PC building construction schemes.

Findings
The findings reveal the need for more sophisticated construction supply chain management solutions which accord with the needs of PC building construction schemes.

Originality/value
The paper concludes by presenting a research framework for developing such a system in the future.
A fungal scent from the cheese
Authors: Kovács Ákos T. 
Published: October 2020

SummaryAssembly of microbial communities is shaped by various physical and chemical factors deriving from their environment, including other microbes inhabiting the certain niche. In addition to direct cell–cell contacts, primary and secondary metabolites impact the growth of microbial community members. Metabolites might act as growth‐promoting (e.g., cross‐feeding), growth‐inhibiting (e.g., antimicrobials) or signalling molecules. In multi‐species microbial assemblies, secreted metabolites might influence specific members of the community, altering species abundances and therefore the functioning of these microcosms. In the current issue, Cosetta and colleagues describe a unique volatile metabolite‐mediated cross‐kingdom interaction that shapes the cheese rind community assembly. The study paves the way of our understanding how fungus‐produced volatile compounds promote the growth of a certain bacterial genus, a principal connection between community members of the cheese rind.
State effectiveness, property rights and entrepreneurial behaviour as determinants of National Innovation
Authors: Idrees Alvina Sabah , Sarwar Saima 
Published: October 2020

AbstractThis article examines the role of entrepreneurial behaviour, property rights and state effectiveness as determinants of national innovation. Entrepreneurial behaviour reflects not only risk‐bearing and risk‐sharing attitudes but also the capacity to undertake innovation activities. Besides, institutions also play an important role in formalising entrepreneurial behaviour that is crucial for a country's innovation. A comparison is made among three groups of countries—that is, factor‐driven, efficiency‐driven and innovation‐driven economies. Panel‐data econometric techniques are applied to undertake empirical analysis, using macro‐level data covering a time period of 7 years (2010–2016). It is observed that entrepreneurial attitudes and entrepreneurial activities play an important role in determining innovation but the impact varies with the level of economic development. A U‐shaped relationship is observed between innovation and entrepreneurial activities. Innovation‐driven economies have strong property rights and effective policy implementation that help build the confidence of prospective entrepreneurs who are attracted by perceived opportunities. Therefore, perceived opportunities have a significant impact only in innovation‐driven economies. Moreover, innovation is highly suppressed in fragile countries, that is, factor‐driven economies that face serious market distortions and inefficiencies caused by weak property rights and state ineffectiveness. However, no significant relationship is found in efficiency‐driven economies.
Changes in health insurance coverage, access to care, and health services utilization by sexual minority status in the United States, 2013‐2018
Authors: Gonzales Gilbert , Henning‐Smith Carrie , Ehrenfeld Jesse M. 
Published: October 2020

AbstractObjectiveTo examine the changes in health insurance coverage, access to care, and health services utilization among nonelderly sexual minority and heterosexual adults between pooled years 2013‐2014 and 2017‐2018.Data SourcesData on 3223 sexual minorities (lesbians, gay men, bisexual individuals, and other nonheterosexual populations) and 86 181 heterosexuals aged 18‐64 years were obtained from the 2013, 2014, 2017, and 2018 National Health Interview Surveys.Study DesignUnadjusted and regression‐adjusted estimates compared changes in health insurance status, access to care, and health services utilization for nonelderly adults by sexual minority status. Regression‐adjusted changes were obtained from logistic regression models controlling for demographic and socioeconomic characteristics.Principal FindingsUninsurance declined for both sexual minority adults (5 percentage points, P < .05) and heterosexual adults (2.5 percentage points, P < .001) between 2013‐2014 and 2017‐2018. Reductions in uninsurance for sexual minority and heterosexual adults were associated with increases in Medicaid coverage. Sexual minority and heterosexual adults were also less likely to report unmet medical care in 2017‐2018 compared with 2013‐2014. Low‐income adults (regardless of sexual minority status) experienced relatively large increases in Medicaid coverage and substantial improvements in access to care over the study period. The gains in coverage and access to care across the study period were generally similar for heterosexual and sexual minority adults.ConclusionsSexual minority and heterosexual adults have experienced improvements in health insurance coverage and access to care in recent years. Ongoing health equity research and public health initiatives should continue to monitor health care access and the potential benefits of recent health insurance expansions by sexual orientation and sexual minority status when possible.

Published: October 2020

AbstractThe aim of the present study was to evaluate the effect of the surface treatments on flexural strengths and flexural modulus of glass‐fibre‐reinforced composite (GFRC) posts. Sixty‐three posts were randomly divided into 9 groups (n = 7), and various surface treatments were performed. The control group was left untreated. Other groups were treated with 9% hydrofluoric acid, sandblasting with 120 µm Al2O3 particles and Er,Cr:YSGG laser irradiation with different powers (1 W, 2 W, 3 W, 4 W, 5 W and 6 W). The samples were subjected to 3‐point bending test, and data were calculated. Statistical analysis was performed. The flexural strengths of fibre posts treated with sandblasting, hydrofluoric acid, 1 W and 2 W laser were statistically similar with control group (P > 0.01). However, the flexural strength of fibre posts treated with 3 W, 4 W, 5 W and 6 W laser was statistically lower than control group (P < 0.01). High laser irradiations cause melting on the post surface and breaks in fibrils.
Histo‐ontogenetic study of the parotid salivary gland of Indian buffalo
Authors: Singh Amandeep , Singh Opinder 
Published: October 2020

AbstractThe present study was aimed at elucidating the histogenesis of parotid gland of buffalo. The study was carried out on buffalo foetuses (n = 36), during different stages of prenatal life. The foetuses were categorised into three groups based on their curved crown rump length (CVRL). The primordial anlage of parotid salivary gland was evident at 40th day of development whereas the primary ducts, in the form of cords, were first observed at 81st day of prenatal life. The capsule formation as well as the lobulation of the gland was initiated at 127th day. At 141st day, the duct system of gland was completed. The terminal tubules attained the structure of acini at 167th day. The myoepithelial cells first appeared as flattened basal cells initially around the developing acinar cells at 167th day. The typical compound tubulo‐acinar nature of the gland was first observed at 185th day. Purely serous acinar cells were seen from 185th day onwards. The micrometrical studies revealed that the mean diameter of acinar cells, intercalated ducts, striated ducts and large ducts increased with the advancement of age. The serous acinar cells were devoid of acidic as well as neutral mucopolysaccharides in prenatal age groups; however, large ducts with goblet cells exhibited positive reaction. Combined PAS‐AB method revealed mixed reaction in acinar cells as well as in large ducts. Fine lipid droplets were observed in intralobular as well as interlobular connective tissue; however, phospholipids were observed in the cell membrane of secretory cells and ducts.

AbstractThe waterbuck (Kobus ellipsiprymnus), though widespread throughout Africa, is suspected to be declining overall. Data on population numbers and structure are lacking for many parts of its range, especially in West Africa, where the subspeciesdefassais found. The aim of the present study was to evaluate the abundance, distribution and attributes of waterbuck populations from the Nazinga Forest Reserve, southern Burkina Faso. We investigated waterbuck population trends in the park using transect data collected in 1985–2019. For the more detailed analyses of population structure and distribution of the animals, we used census data gathered during 2019. Most animals were adults (46.6%), and the sex ratio was heavily skewed towards females (5:1). Most animals were concentrated along the larger rivers. There was no influence of poacher activity on waterbuck distribution. In the long term (1985–2019), the population dynamics of waterbuck can be roughly divided into two main periods: a phase of population increase from 1985 to 2005, and one of ongoing population collapse from 2007 to 2019. Although the declining population trend was obvious, coefficients of determination were low indicating that the years explained poorly the number of individuals and the number of sightings obtained. Waterbuck numbers in the Nazinga Forest Reserve are declining, but we found no single reason to explain this trend. It is likely that a combination of factors, including global warming (increased aridity) and illegal activities such as poaching, is responsible. Because there are probably multiple reasons for the observed waterbuck population decline in our study area, we suggest that a multifaceted approach should be adopted in order to enhance the conservation status of the local waterbuck populations.
