Event-Related potentials in an associative word pair learning paradigm
Authors: Farshad Maryam , Pavlov Yuri G. , Kotchoubey Boris 
Published: August 2019

AbstractThe study investigated the effect of unintentional learning of semantically unrelated word pairs on event-related brain potentials. Two experiments were conducted, in whose acquisition phase participants listened to five pairs of semantically unrelated words, each pair being repeated twenty times. In the test phase of Experiment 1, these “old” pairs were presented mixed with “new” pairs containing other words. In the test phase of Experiment 2, a third condition was added in which the first word in a pair was one of the words presented during acquisition but the second word was new. In both experiments, the second word in new word pairs elicited an N400 and a late (550-1000 ms) frontal positivity. The amplitude of the N400 to new second words in Experiment 2 was significantly larger when the first word in the pair was an old (previously learnt) word, as compared with the condition in which both first and second words were new. The results indicate that, in addition to a repetition effect, unintentional learning of word pairs results in building new associations between previously unrelated words.

AbstractMicroelectrode arrays (MEAs) provide the means to record electrophysiological activity fundamental to both basic and clinical neuroscience (e.g. brain-computer interfaces). Despite recent advances, current MEAs have significant limitations – including low recording density, fragility, expense, and the inability to optimize the probe to individualized study or patient needs. Here we address the technological limitations through the utilization of the newest developments in 3D nanoparticle printing.1 Our ‘CMU Arrays’ possess previously impossible electrode densities (> 6000 channels/cm2) with tip diameters as small as 10 μm. Most importantly, the probes are entirely customizable owing to the adaptive manufacturing process. Any combination of individual shank lengths, impedances, and layouts are possible. This is achieved in part via our new multi-layer, multi material, custom 3D-printed circuit boards, a fabrication advancement in itself. This device design enables new experimental avenues of targeted, large-scale recording of electrical signals from a variety of biological tissues.
Synaptic and intrinsic plasticity coordinate spike output in cerebellar Purkinje cells
Authors: Shim Hyun Geun , Kim Sang Jeong 
Published: August 2019

SummaryLearning has been thought to be implemented by activity-dependent modifications of synaptic weight and intrinsic excitability. Here, we highlight how long-term depression at parallel fiber to Purkinje cell synapses (PF-PC LTD) and intrinsic plasticity of PCs coordinate the postsynaptic spike discharge from C57BL/6 male mice. Intrinsic plasticity of PCs in the flocculus matched the timing rules and shared intracellular signaling for PF-PC LTD. Notably, the intrinsic plasticity was confined to the dendritic branches where the synaptic plasticity is formed. Besides, when either synaptic or intrinsic plasticity was impaired, the impact of PF inputs was less reflected by the spike output of PCs. In conclusion, synergies between synaptic and intrinsic plasticity may play a role in tuning the PC output, thereby achieving optimal ranges of output.
The application of an ANP-Fuzzy comprehensive evaluation model to assess lean construction management performance
Authors: Li X.K. , Wang X.M. , Lei L. 
Published: August 2019

Purpose
The purpose of this paper is to propose a method for assessing the lean construction management performance (LCMP) of engineering projects using the analytic network process-fuzzy comprehensive evaluation (ANP-FCE) model.

Design/methodology/approach
Literature review and questionnaire surveys were used to achieve an evaluation index system for LCMP. The data needed to calculate the weights of the indices were derived from questionnaire surveys. The ANP and the Super Decisions (SD) software were used to calculate the weights of the indices and verify the validity of the weights. The FCE was adopted to carry out a comprehensive evaluation of LCMP, and the validity of the evaluation results was verified by applying the validity degree of maximum membership principle. The applicability of the method for evaluating LCMP was validated by empirical research.

Findings
The proposed method for assessing the LCMP using the ANP-FCE model is validated to be feasible. Decision makers can easily identify the strengths and weaknesses of lean construction (LC) management of the evaluated project from the evaluation results.

Research limitations/implications
Some subjectivity may exist in the assessment process due to questionnaire surveys, and only one case has been studied to validate the applicability of the method. Therefore, researchers are encouraged to increase the number of LC experts and cases over the world to make the proposed method more standard.

Practical implications
The research is expected to propose an assessment method of LCMP for construction enterprises, provide a reference to develop assessment standards for LCMP for building associations or governments and help decision makers know the improving path of LC management.

Originality/value
This research contributes to the literature by summarizing the commonly used lean management tools for quality, cost, time, safety and organization in practice, and proposing a novel approach for assessing the LCMP of engineering projects. The study is useful for researchers, project managers and decision makers engaged in LC.
Leading learning in content areas
Authors: Lochmiller Chad R. , Cunningham Kathleen M.W. 
Published: August 2019

PurposeThe purpose of this paper is to report findings from a systematic literature review that explore how recent research on instructional leadership has addressed the role of mathematics and science instruction.Design/methodology/approachUsing Hallinger’s (2014) approach to conducting systematic reviews, the review included 109 peer-reviewed articles published since 2008 in leading mathematics and science education journals. Ana prioricoding scheme based upon key leadership behaviors articulated in Hitt and Tucker’s (2016) unified leadership framework informed the analysis presented.FindingsResults indicate that leaders support content area instruction by facilitating high-quality instructional experiences through curricular and assessment leadership. Leadership frequently involves establishing organizational conditions that support teachers’ efforts to improve their own practice instead of direct leadership action on the part of instructional leaders. This support takes different forms and can include distributing leadership to teacher leaders with content area experience as well as using resources strategically to provide professional development or instructional coaching.Originality/valueThe review strengthens the connections between the instructional leadership, mathematics and science literatures, and identifies some of the leadership practices that these literatures deem important for instructional improvement. The review also reveals the potential for future research exploring the influence of a particular content area on supervisory practice and leadership discourse.
CSR reporting and assurance legitimacy: a client–assuror dyad investigation
Authors: Hickman Leila Emily , Cote Jane 
Published: August 2019

Purpose
Drawing on new insights from the experiences and perspectives of a prominent reporting client and its assurance team, the purpose of this paper is to explore the question: what are challenges to the legitimacy of corporate social responsibility (CSR) reporting and assurance?

Design/methodology/approach
Using a qualitative research approach, in-depth, semi-structured interviews are conducted with a Fortune 200 firm’s Vice President responsible for CSR oversight (including CSR reporting), and with the report’s assurance team from a Top 20 accounting firm. Questions are informed by existing literature, and analysis focuses on new insights that conform to, or contrast with, prior studies in areas that may challenge the legitimacy of CSR reporting.

Findings
The study documents that reporting and assurance may often serve the respective commercial and professional interests of the firm and the assuror, rather than providing accountability to the public interest. Specifically, the authors find that legitimacy-challenging instances of managerial capture of CSR reporting may co-exist in a firm with management-as-CSR-champion, in contrast with existing literature. Prior research has assumed these two constructs are not likely to co-exist within a single organization. The interviews suggest that managerial influence is fostered by the lack of reporting standards and the absence of agreement regarding the over-arching purpose of CSR reports and their assurance.

Research limitations/implications
Going forward, researchers should consider the multifaceted role management can play in CSR reporting and assurance, rather than treating managerial capture and management-as-champion as mutually exclusive. Future research could also examine how standards may balance desired comparability with flexibility in CSR reporting.

Practical implications
The study will interest report users who may assume that a seemingly supportive management would not play a restrictive role in the reporting and assurance processes. Reporters and assurors will benefit from reading the perspectives provided by professionals engaged in similar work, including the challenges they face, such as the consequences resulting from the lack of standards for CSR reporting and assurance.

Originality/value
The study is the first to provide a behind-the-scenes view of the report–assuror dyad by interviewing both the reporting firm and the assurance team engaged on the same CSR report.
A quantile regression approach to trail financial performance of manufacturing firms
Authors: Nanda Swagatika , Panda Ajaya Kumar 
Published: August 2019

Purpose
The purpose of this paper is to track the financial performance of manufacturing firms at different levels of their conditional quantiles. It also analyzes the relevance of revenue and cost channels along with key firm-specific parameters that influence firm’s profitability.

Design/methodology/approach
The study analyses a sample of 1,000 manufacturing firms over a study period spanning from 2000 to 2016. It uses both quantile regression and panel ordinary linear square (OLS) models to analyze the financial performance of the firms.

Findings
The study finds large scale of heterogeneity among the firms under different quantiles of profitability. Export earnings, firm size, asset turnover and volatility of exchange rate are the decisive determinants of financial performance across all quantiles. Financing assets by current debt is negatively impacting return on assets and return on capital employed of firms from lower quantile whereas profitability is positively impacted if they are financed by long term debt. Debt financing of assets does not make any sense for firms with high quantile of profitability. The study also finds that quantile regression approach is a better method than panel OLS models in the presence of highly heterogeneous and non-normal distributions.

Research limitations/implications
This study is limited to the financial performance of manufacturing firms and does not consider service sector which is also equally competitive. However, a sector wise analysis of firm’s profitability could be more meaningful than comparing all the firms in one basket of manufacturing domain.

Practical implications
The research findings have both practical as well as policy implications. Practically, the study helps the firm managers to identify critical success factors that significantly influence firm’s financial performance at different levels of profitability. It also helps the policy makers to align policy focus to stabilize firms at lower level of profitability and also to manage conducive business environment for all firms at different levels of their profitability.

Originality/value
The study provides a deep theoretical underpinning of literatures on firm’s financial performance and empirically investigates it using advanced methodology. The robust estimates of the study ensure to analyze financial performance under revenue and cost channels at diverse level of their profitability.
Using Latin America as a research laboratory
Authors: Borda Reyes Armando , Newburry William , Carneiro Jorge , Cordova Carlos 
Published: August 2019

Purpose
This paper aims to use Latin America as a laboratory to better understand the relationship between inward foreign direct investment (IFDI) and outward foreign direct investment (OFDI) (both in total as well as in regional flows) and also examine the moderating effect of trade openness on that relationship. Latin America is an ideal study context for this purpose because of the relative homogeneity of its countries, which reduces confounding effects and increases comparability.

Design/methodology/approach
This paper uses longitudinal panel regression models with moderation effects. Secondary data were gathered on IFDI (per country and per country-sector), OFDI (total per country and region-targeted per country) and on trade openness from 11 Latin American countries.

Findings
IFDI in natural resources is positively associated with OFDI in both overall total flows and regional flows. The effect of IFDI in manufacturing has a consistent negative effect on total OFDI. IFDI in services has positive effects on total OFDI. Additionally, trade openness moderates positively the relationship between total IFDI and both total OFDI and regional OFDI. As a consequence, the authors found evidence suggesting that the relation between IFDI and OFDI in Latin America is positively moderated by trade openness.

Originality/value
The authors explored the nature of the impact of IFDI on the capacity of the recipient country to compete abroad as expressed by its OFDI flows. Specifically, they elucidated whether trade openness can be considered a suitable mechanism for home country firms to leverage potential spillovers provided by foreign entrants.
Psychological barriers in the cryptocurrency market
Authors: Fonseca Vítor , Pacheco Luís , Lobão Júlio 
Published: August 2019

Purpose
The purpose of this paper is to study the existence of psychological barriers in cryptocurrencies.

Design/methodology/approach
To detect psychological barriers, the authors perform a uniformity test, a barrier hump test, a barrier proximity test and conditional effects test to a sample comprised by the daily closing quotes of six of the most liquid cryptocurrencies.

Findings
The results evidence the existence of psychological barriers in four of the cryptocurrencies under scrutiny, namely, Bitcoin, Dash, NEM and Ripple.

Practical implications
The fact that the cryptocurrency market has a high share of unexperienced investors and presents several cases of psychological barriers is consistent with the hypothesis that that class of investors is particularly prone to the behavioral biases which cause psychological barriers.

Originality/value
This paper studies, for the first time, the existence of psychological barriers in the market of cryptocurrencies.
Herding in frontier markets: evidence from the Balkan region
Authors: Economou Fotini 
Published: August 2019

Purpose
The purpose of this paper is to examine herding in four frontier markets in the Balkan region, namely, Bulgaria, Croatia, Romania and Slovenia, from October 2000 to December 2016.

Design/methodology/approach
The author employs Chang et al.’s (2000) cross-sectional dispersion approach to capture herding, while also testing for the global financial crisis’ effects and the European Union (EU)/Euro zone accession effects over herding. Potential asymmetric herding effects conditional on market performance, domestic volatility, German and US investor sentiment are also examined. Finally, the cross-market herding dynamics of the region are also explored.

Findings
Overall, Romania exhibits the most extensive evidence of herding across various estimations. The empirical results indicate that cross-market herding dynamics within the region generate stronger herding (compared to the herding observed within each stock market individually), suggesting that Balkan stock exchanges’ growing financial integration leads their herding to be “imported”, rather than domestically motivated.

Practical implications
The findings provide useful insights for regulators in frontier markets, considering the destabilising potential of herding; they are also of particular interest to the investment community for reasons of international asset allocation, diversification and hedging strategies.

Originality/value
This study contributes to the limited herding literature regarding frontier markets and provides novel findings regarding the herding dynamics in the Balkan region, the EU/Euro zone accession’s effect and global factors’ impact on herding estimations.
Tourism, ageing and the demographic time bomb – the implications of dementia for the visitor economy: a perspective paper
Authors: Connell Joanne , Page Stephen 
Published: August 2019

Purpose
This paper aims to examine the development of research on ageing and demography and the implications for the study of tourism. It examines the demographic time bomb created by an ageing population and the implications of complex health conditions, such as dementia, for the visitor economy. Practical measures are identified with an example of a “call to action” for small to medium-sized tourism businesses.

Design/methodology/approach
This review is based on existing knowledge of ageing and draws upon a historical timeline that stretches from the nineteenth century to 2100.

Findings
The impact of complex health conditions such as dementia will pose major challenges for the visitor economy and will require behavioural change within existing business practices to accommodate the needs of people with dementia and their carers.

Research limitations/implications
Major changes in business practices and the development of more holistic views of accessibility will be needed to accommodate an ageing population in 2100. Some of the initial changes businesses can make are outlined in a “call to action” leaflet extract.

Practical implications
Businesses will need to focus more on customer care practices to ensure that they can accommodate the complex needs of people with dementia and their carers as they continue to pursue the tourism and leisure activities that they have grown accustomed to.

Social implications
Businesses will need to become more fully engaged with new agendas on accessibility, inclusivity and good business practice that raise significant ethical, financial and legal issues for the way they do business in the future.

Originality/value
The paper sets out an overarching grand societal challenge around ageing that is now confronting many countries worldwide. As part of that agenda, this paper raises the issue of hidden conditions such as dementia. The paper seeks to stimulate a wider debate for researchers and policymakers going forward, framed around the following questions which arise from the paper: How is dementia understood as a hidden condition in the visitor economy? To what extent is there awareness and action in the visitor economy sector? What can the visitor economy sector do to address issues of inclusivity and dementia?
AoStuA, an APSES transcription factor, regulates the conidiation, trap formation, stress resistance and pathogenicity of the nematode‐trapping fungus Arthrobotrys oligospora

Published: August 2019

SummaryThe APSES protein family comprises a conserved class of fungus‐specific transcriptional regulators. Some members have been identified in partial ascomycetes. In this study, the APSES protein StuA (AoStuA) of the nematode‐trapping fungus Arthrobotrys oligospora was characterized. Compared with the wild‐type (WT) strain, three ΔAoStuA mutants grew relatively slowly, displayed a 96% reduction in sporulation capacity and a delay in conidial germination. The reduced sporulation capacity correlated with transcriptional repression of several sporulation‐related genes. The mutants were also more sensitive to chemical stressors than the WT strain. Importantly, the mutants were unable to produce mycelial traps for nematode predation. Moreover, peroxisomes and Woronin bodies were abundant in the WT cells but hardly found in the cells of those mutants. The lack of such organelles correlated with transcriptional repression of some genes involved in the biogenesis of peroxisomes and Woronin bodies. The transcript levels of several genes involved in the cAMP/PKA signalling pathway were also significantly reduced in the mutants versus the WT strain, implicating a regulatory role of AoStuA in the transcription of genes involved in the cAMP/PKA signalling pathway that regulates an array of cellular processes and events. In particular, AoStuA is indispensable for A. oligospora trap formation and virulence.
A Comprehensive Review on Food Applications of Terahertz Spectroscopy and Imaging
Authors: Afsah‐Hejri Leili , Hajeb Parvaneh , Ara Parsa , Ehsani Reza J. 
Published: August 2019

AbstractFood product safety is a public health concern. Most of the food safety analytical and detection methods are expensive, labor intensive, and time consuming. A safe, rapid, reliable, and nondestructive detection method is needed to assure consumers that food products are safe to consume. Terahertz (THz) radiation, which has properties of both microwave and infrared, can penetrate and interact with many commonly used materials. Owing to the technological developments in sources and detectors, THz spectroscopic imaging has transitioned from a laboratory‐scale technique into a versatile imaging tool with many practical applications. In recent years, THz imaging has been shown to have great potential as an emerging nondestructive tool for food inspection. THz spectroscopy provides qualitative and quantitative information about food samples. The main applications of THz in food industries include detection of moisture, foreign bodies, inspection, and quality control. Other applications of THz technology in the food industry include detection of harmful compounds, antibiotics, and microorganisms. THz spectroscopy is a great tool for characterization of carbohydrates, amino acids, fatty acids, and vitamins. Despite its potential applications, THz technology has some limitations, such as limited penetration, scattering effect, limited sensitivity, and low limit of detection. THz technology is still expensive, and there is no available THz database library for food compounds. The scanning speed needs to be improved in the future generations of THz systems. Although many technological aspects need to be improved, THz technology has already been established in the food industry as a powerful tool with great detection and quantification ability. This paper reviews various applications of THz spectroscopy and imaging in the food industry.
