Age- and sex- dependent changes in locus coeruleus physiology and anxiety-like behavior in response to acute stress
Authors: Borodovitsyna Olga , Chandler Daniel J 
Published: November 2020

AbstractAdolescence is a critical period of development with increased sensitivity toward psychological stressors. Many psychiatric conditions emerge during adolescence and animal studies have shown that that acute stress has long-term effects on hypothalamic pituitary adrenal axis function and behavior. We recently demonstrated that acute stress produces long-term electrophysiological changes in locus coeruleus and long-lasting anxiety-like behavior in adolescent male rats. Based on prior reports of increased stress sensitivity during adolescence and increased sensitivity of female locus coeruleus toward corticotropin releasing factor, we hypothesized that the same acute stressor would cause different behavioral and physiological responses in adolescent female and adult male rats one week after stressor exposure. In this study, we assessed age and sex differences in how an acute psychological stressor affects corticosterone release, anxiety-like behavior, and locus coeruleus physiology at short- and long-term intervals. All groups of animals responded to stress with elevated corticosterone levels at the acute time point. One week after stressor exposure, adolescent females showed decreased firing of locus coeruleus neurons upon current injection and increased exploratory behavior compared to controls. The results were in direct contrast to changes observed in adolescent males, which showed increased anxiety-like behavior and increased spontaneous and induced firing locus coeruleus neurons a week after stressor exposure. Adult males were both behaviorally and electrophysiologically resilient to the long-term effects of acute stress. Therefore, there may be a normal developmental trajectory for locus coeruleus neurons which promotes stress resilience in adults, but stressor exposure during adolescence perturbs their function. Furthermore, while locus coeruleus neurons are more sensitive to stressor exposure during adolescence, the effect varies between adolescent males and females. These findings suggest that endocrine, behavioral, and physiological responses to stress vary among animals of different age and sex, and therefore these variables should be taken into account when selecting models and designing experiments to investigate the effects of stress. These differences in animals may also allude to age and sex differences in the prevalence of various psychiatric illnesses within the human population.

Published: November 2020

AbstractC4photosynthesis optimizes plants carbon and water relations, allowing high photosynthetic rate with low stomatal conductance. Stomata have long been believed as a part of C4syndrome. However, it remains unclear how stomata traits evolved along the path from C3to C4. Stomatal patterning was examined inFlaveriagenus, a model for studying C4evolution. Comparative, transgenic and semi-in-vitroexperiments were used to study molecular basis that underlies stomatal traits along C4evolution. Novel results: the evolution from C3to C4species through intermediate species is accompanied by a stepwise rather than an abrupt change in the stomatal traits. The initial change occurs near Type II and dramatic change occurs at the C4-like species. On the road to C4, stomata become less in number but bigger in size and changes in stomatal density dominates changes in maximum stomatal conductance (gsmax). The reduction ofFSTOMAGENexpression underlies alteredgsmaxbetweenFlaveriaspecies with different photosynthetic pathways and likely occurs in other C4lineages. Our study provides insight into the pattern, mechanism and role of stomatal evolution along the road towards C4. This work highlights the stomatal traits in the current C4evolutionary model and the co-evolution of photosynthetic pathway and stomata.
Magnetoelectric effect in hybrid composite material
Authors: Mech Rafal 
Published: November 2020

PurposeInvestigations over new types of materials as a potential power source for different types of devices were raised dramatically in the last few years. It is connected especially with global needs and that most of the devices in our world need electricity to work. In this paper, an investigation on magnetoelectric effect in the magnetostrictive-piezoelectric composite material is presented.Design/methodology/approachAn author's research setup for investigation of magnetoelectric effect in the developed novel material was prepared. The new composite material was made of magnetostrictive particles of Terfenol-D and lead zirconium titanate (PZT) material.FindingsObtained results show that changes in an electric voltage output from the prepared material are highly dependent on the changes in external magnetic field. It was found out that rate of changes of magnetic field around composite material is one of the most important factors which has influence on the magnetoelectric effect. Taking into account the obtained results, it was proven that prepared hybrid material shows magnetoelectric effect in the case of work in alternating magnetic field.Originality/valueThis phenomenon might be used in a field of energy harvesting as potential power source for devices with low power consumption. Moreover, this new material gives an opportunity to be used as an additional gauge for determination of deformation or crack propagation in the samples during fatigue tests.
Application of text mining in identifying the factors of supply chain financing risk management
Authors: Ying Hao , Chen Lujie , Zhao Xiande 
Published: November 2020

PurposeThis study aims to clarify the risk management practices of banks as supply chain finance (SCF) service providers.Design/methodology/approachUsing 4,014 evaluation and approval reports, this study constructed five risk management factors and examined their functions with secondary data. Two text-mining techniques (i.e. word sense induction, TF–IDF) were used to equip the classic routine of dictionary-based content analysis.FindingsThis research successfully identified four important risk management factors: relationship-based assessment, asset monitoring, cash flow monitoring and supply chain collaboration. The default-preventing effect of these factors are different and contingent on the type of financing contexts (i.e. preshipment, postshipment).Practical implicationsThe empirical evidences provide practical implications for SCF service providers to manage risk. SCF service providers are suggested to pay more attention to cash flow monitoring when providing postshipment financing services and shift the focus to relationship building and supply chain collaboration when providing preshipment financing services.Originality/valueThe study shows that a large volume of textual materials can provide adequate clues for researches as long as they are mined with suitable analytic techniques and approaches. Based on the results, SCF service providers can identify problems of their operations and directions for improvement. In addition, the risk management vocabulary from the E&A reports can be utilized by SCF service providers to digitize their loan approving process and, further, to facilitate the decision-makings.

Published: November 2020

PurposeThis study examines mosquito-borne diseases and health hazard of using mosquito repellents in Bangladesh. This study also targets to explore the use of different mosquito repellents and associated health hazard between slum and residential people.Design/methodology/approachThis study has applied a stratified systematic sampling technique taking 120 adult individuals from residential and slum areas covering users and non-users of mosquito repellents of Khulna city, Bangladesh. A structured questionnaire has been used to collect data from respondents.FindingsEconometric techniques are exercised to examine the occurrence, severity and duration of different respiratory diseases. Results exhibit that poor and less-educated slum people are more prone to face respiratory diseases compared to residential people. The health cost of slum and residential people is estimated US$ 134 and US$ 9, respectively.Practical implicationsRelevant stakeholders under public health programs should spread awareness among people regarding the negative health effect of using mosquito repellent, encourage them to limit the use of harmful repellent and instead use herbal product (neem coil), avoid using repellent in living room rather use outside of room and close window and use proper bed net at night.Originality/valueThis study underpins arranging public health programs and taking averting actions as an impetus to raise consciousness toward the negative health effect of using mosquito repellents.

Authors: Helens-Hart Rose , Engstrom Craig 
Published: November 2020

PurposeThis study aims to present empathy as an ideal characteristic of consultants for talent development (CTD). It provides a contextualized look at how empathy manifests in CTD practice and offers practical guidance for improving CTD empathy skills, and thus their performance in the corporate classroom.Design/methodology/approachIn total, 34 interviews with talent development professionals were analyzed using a qualitative coding process.FindingsApart from functional and industry knowledge, a collection of soft skill themes emerged from the analysis, including active listening, perspective taking, audience adaptation and communication style. These themes coalesced around the construct of empathy and provided a framework with which to understand how empathy is expressed and leveraged in talent development consulting.Originality/valueWhile business research has explored the importance of empathy in some workplaces, to the knowledge, this is the first study focusing on the empathy of CTDs. In addition, literature paints a fractured and anecdotal picture of soft skills for the ideal consultant. This research helps CTDs, those who hire them and business educators target essential skills for facilitating workplace learning.
Choosing murabahah to the purchase orderer (MPO) vehicle financing: an Islamic theory of consumer behaviour perspective
Authors: Amin Hanudin 
Published: November 2020

Purpose
This study aims to examine the effects of Islamic altruism, level of iman and maqasid consumer index on young intellectuals’ willingness to choose murabahah to the purchase orderer (MPO) vehicle financing. Besides, the role of the level of iman or faith as a mediator is examined.

Design/methodology/approach
Earlier studies have reported the limited application of the Islamic theory of consumer behaviour (ITCB) to the vehicle financing context. This lack of theoretical foundation might provide a potential explanation for the mixed empirical support that has been found. This study, therefore, uses the ITCB to study young intellectuals’ willingness to take up the facility. The data were analysed using partial least squares based on 312 respondents.

Findings
The results obtained from this study confirm that the ITCB should be applied to understand the willingness behaviour amongst young graduates in selecting MPO vehicle financing. The level of iman was found a key factor not only as an independent variable but also as a mediator.

Research limitations/implications
This study is limited in terms of its generalisation and research context.

Practical implications
New insight into patronage factors for MPO vehicle financing is provided along with the applicability outcome of the ITCB.

Originality/value
This paper applies the ITCB into the MPO vehicle financing context and using young intellectuals to examine the validity and reliability of the ITCB.
The need for accounting-integrated data streams for scenario-based planning in primary production: responding to COVID-19 and other crises
Authors: Tingey-Holyoak Joanne Louise , Pisaniello John Dean 
Published: November 2020

PurposeThis study aims to explore the need for improved data sources and models for COVID-19 and climate-related risk scenario analysis in primary production. The COVID-19 pandemic is impacting global markets for agricultural produce, making short-term forecasting highly uncertain. Meanwhile climate-related risk continues for agricultural businesses. Farmers and their accountants need to plan and make estimates about the potential effect of COVID-19 and ongoing climate risks to their natural and financial capital and so they need accounting-integrated biophysical and socio-economic data streams.Design/methodology/approachThis research note reviews the current state of scenario-based planning for COVID-19 and other risks for Australian businesses generally, in addition to planning for farming businesses more specifically. Discussion of the authors’ current research in integrating accounting and farming data for water-related risk caused by climate and other challenges is presented as an analogous case.FindingsReview and analogous case comparison demonstrate the need for farm data to be integrated more efficiently and effectively with accounting data for accurate scenario planning for COVID-19 and other risks, including those posed by climate.Practical implicationsWhile not strangers to the need for scenario analysis, given exposure to ever-increasing natural resource and climate variability, this research note highlights how primary producers and their accountants require increased accounting-integrated farm data and systems to make judgements, assumptions and estimates about the potential effect of COVID-19 and ongoing climate risks to their business.Social implicationsThe sustainability of the agricultural sector is of great relevance to all of us and so the development of tools and resources that can assist food producers in times of ongoing climate pressures and new crises, such as COVID-19, is important. Better understanding of such risks can help farm businesses develop effective strategies which minimise the potential loss of agricultural value resulting in improved flows of greater capital value for society.Originality/valueThrough application to the analogous case of water-related risk and decision-making, the research note demonstrates that linking of biophysical and accounting data streams will be essential for evidence-backed numbers included in scenario plans with enough legitimacy to be interrogated inside and outside of the business. The “best estimate of the directors” is no longer enough in challenging socio-economic and biophysical times ahead for primary producers.

PurposeThe purpose of this paper is to present a quantitatively supported explanation of the intellectual development, the schools of thought and the sub-areas of the food cold chain (FCC) research to derive meaningful avenues for future research.Design/methodology/approachThis study builds on bibliometric analysis and network analysis to systematically evaluate a sample of 1,189 FCC articles published over the past 25 years. The descriptive statistics and science mapping approaches using co-citation analysis were performed with VOSviewer software.FindingsThe findings reveal a state-of-the-art overview of the top contributing and influential countries, authors, institutions and articles in the area of FCC research. A co-citation analysis, coupled with content analysis of most co-cited articles, uncovered four underlying research streams including: application of RFID technologies; production and operation planning models; postharvest waste, causes of postharvest wastage and perishable inventory ordering polices and models; and critical issues in FCC. Current research streams, clusters and their sub-themes provided meaningful discussions and insights into key areas for future research in FCC.Originality/valueThis study might reshape practitioners’, researchers’ and policy-makers’ views on the multifaceted areas and themes in the FCC research field, to harness FCC’s benefits at both strategic and tactical level. Finally, the research findings offer a roadmap for additional research to yield more practical and modeling insights that are much needed to enrich the field.
High-precision width measurement method of laser profile sensor
Authors: Feng Yu , Tao Wei , Feng Yiyang , Yin Xiaoqia , Lv Na , Zhao Hui 
Published: November 2020

Purpose
Although a laser profile sensor (LPS) can be used to measure dimensions, the “shadow region” generally degrades the accuracy and precision of width measurements. The accuracy and precision of such measurements should be improved.

Design/methodology/approach
In this paper, the authors propose herein a technique that combines high dynamic range (HDR) imaging with logistic fitting. First, a HDR image is composed of several images acquired with different exposure times, which augments the grayscale of the object profile and significantly reduces overexposure. Next, the profile is fit to a logistic function, which provides accurate and precise edge coordinates. Finally, given the edge coordinates, the object width is calculated.

Findings
To verify the stability of this logistic algorithm, the authors simulate different noise conditions and different degrees of incomplete edge data. In addition, the progressiveness of the algorithm is demonstrated by comparing the results with those of other algorithms and with the height measurement. Furthermore, the suitability of the system is verified experimentally.

Research limitations/implications
Because of the limitation of the condition of laboratory, in the experimental section, this paper cannot represent perfectly the industrial situation. It makes this section limited in demonstration.

Originality/value
In this paper, the results show that the measurement accuracy and precision of the width is improved and exceeds that of the height measurement. The proposed HDR imaging method with logistic fitting may be applied to LPS width measurements, which should significantly aid the development of LPSs.

Published: November 2020

AbstractOur study describes in detail the binding mechanism between the main flavonoids that were extracted from onion skins by supercritical CO2 and peptides from whey proteins, from the perspective of obtaining multifunctional ingredients, with health‐promoting benefits. The supercritical CO2 extract had 202.31 ± 11.56 mg quercetin equivalents/g DW as the major flavonoid and antioxidant activity of 404.93±1.39 mM Trolox/g DW. The experiments on thermolysin‐derived peptides fluorescence quenching by flavonoids extract allowed estimating the binding parameters, in terms of binding constants, and the number of binding sites. The thermodynamic analysis indicated that the main forces involved in complex formation were hydrogen bonds and van der Waals interactions. Molecular docking tests indicated that peptide fluorescence quenching upon gradual addition of onion skin extract might be due to flavonoids binding by Val15‐Ser21. All 7 to 14 amino acids long peptides appeared to have affinity toward quercetin‐3,4’‐O‐diglucoside and quercetin‐4’‐O‐monoglucoside. The study is important as a potential solution for reuse of valuable resources, underutilized, such as whey peptides and yellow onion skins flavonoids for efficient microencapsulation, as a holistic approach to deliver healthy and nutritious food.Practical ApplicationA growing interest was noticed in the last years in investigating the interactions between proteins and different biologically active compounds, such as to provide knowledge for efficient development of new food, pharmaceutical, and cosmetic products. Recent studies suggest that flavonoid–protein complexes may be designed to improve the functional performance of the flavonoids. The results obtained in this study bring certain benefits in terms of exploiting the bioactive potential of both flavonoids and bioactive peptides, for developing of formulas with improved functional properties.

AbstractObjectiveThis study aimed to investigate the characteristics of bloodstream infections (BSIs) in older patients and describe the differences between community‐acquired, hospital‐acquired and health care–associated BSIs.MethodsA prospective observational study was conducted at the University Hospital of Heraklion, Crete, Greece. Epidemiology, clinical characteristics and outcomes of BSIs were recorded.ResultsDuring a four‐year period, 113 BSIs were recorded. Of them, 42% occurred in male patients; patients’ mean age was 80 years. BSIs were community‐acquired in 76% of patients, hospital‐acquired in 12% and health care–associated in 12%. The most commonly isolated bacteria were E coli and K pneumoniae. Thirty‐day mortality from detection of BSIs was 27%. Patients with fever, without septic shock and with appropriate empirical treatment were less likely to die.ConclusionCommunity‐acquired, health care–associated and hospital‐acquired BSIs had different presentation, microbiology and outcomes. Older patients had a high mortality. The absence of fever, inappropriate empirical treatment and septic shock were independent mortality predictors.
