ABA-dependent and ABA-independent functions of RCAR5/PYL11 in response to cold stress
Authors: Lim Chae Woo , Lee Sung Chul 
Published: August 2019

AbstractArabidopsis thaliana has 14 abscisic acid (ABA) receptors—PYR1/PYLs/RCARs—which have diverse and redundant functions in ABA signaling; however, the precise role of these ABA receptors remains to be elucidated. Here, we report the functional characterization of RCAR5/PYL11 in response to cold stress. Expression of RCAR5 gene in dry seeds and leaves was ABA-dependent and ABA-independent, respectively. Under cold stress conditions, seed germination was markedly delayed in RCAR5-overexpressing (Pro35S:RCAR5) plants, but not in Pro35S:RCAR5 in ABA-deficient (aba1-6) mutant background. Leaves of Pro35S:RCAR5 plants showed enhanced stomatal closure—independent of ABA—and high expression levels of cold, dehydration, and/or ABA-responsive genes; these traits conferred enhanced freezing tolerance. Our data suggest that RCAR5 functions in response to cold stress by delaying seed germination and inducing rapid stomatal closure via ABA-dependent and ABA-independent pathways, respectively.

PurposeIn this study, electrochemical deposition method which have cheaper equipment than thermal spraying methods and is available for the production of composite coatings were used.Design/methodology/approachComposite coatings were electrodeposited from a Watts's bath solution in which the suspended Cr3C2-NiCr particles were dispersed in the bath solution during deposition. Potentiodynamic polarization and electrochemical impedance spectroscopy techniques have been used to evaluate the corrosion resistance of the composite coating in the 3.5 Wt.% NaCl solution.FindingsIt was found that the submicron Cr3C2-NiCr particles distributed uniformly in the coating and depend on the current density of deposition, different amount of particles can be incorporated in the coating. The results showed that the corrosion resistance of the Ni/ Cr3C2-NiCr composite coatings is more comparable to the pure nickel coating.Originality/valueProduction of Ni-base composite coating from an electrolytic bath containing Cr3C2-NiCr particles is possible via electrodeposition.
Omnichannel fulfillment strategies: defining the concept and building an agenda for future inquiry
Authors: Taylor Daniel , Brockhaus Sebastian , Knemeyer A. Michael , Murphy Paul 
Published: August 2019

Purpose
Since the emergence of e-commerce uprooted traditional brick-and-mortar retail in the early 2000s, many retailers have reacted by first independently servicing both the online and in-store channels (multichannel retailing) and subsequently integrating both channels to provide a seamless front-end customer interface (omnichannel retailing). Accordingly, firms had to adjust their logistics and supply chain management (SCM) processes from fulfilling orders for each channel separately to integrating channels on the back-end (omnichannel fulfillment). This development is mirrored by an emerging stream of academic publications. The purpose of this paper is to provide a snapshot of the current state of omnichannel fulfillment research via a systematic literature review (SLR) in order to identify omnichannel fulfillment strategies and to establish an agenda for future inquiry.

Design/methodology/approach
This SLR is based on 104 papers published in peer-reviewed journals through December 2018. It employs a six-step process, from research question to the presentation of the insights.

Findings
All selected manuscripts are categorized based on demographics such as publication date, outlet, methodology, etc. Analysis of the manuscripts suggests that the integration of fulfillment channel inventory and resources is becoming an important objective of fulfillment management. Appropriate omnichannel strategies based on retailer attributes are not well understood. Industry specific research has been conducted necessitating generalized extension for retailers. These findings provide a clear opportunity for the academic community to take more of the lead in terms of knowledge creation by proposing paths for industry pursuit of channel integration to successfully implement omnichannel fulfillment. Opportunities for future inquiry are highlighted.

Originality/value
This manuscript proposes a definition of omnichannel fulfillment strategies and identifies fulfillment links that are used interchangeably across channels as the key delimiter between omnichannel fulfillment strategies and related concepts. Six omnichannel fulfillment strategies from the extant literature are identified and conceptualized. Future research opportunities around omnichannel fulfillment, potential interdependencies between the established strategies and their impact on related SCM issues such as distribution and reverse logistics are detailed.
Retaining users after privacy invasions
Authors: Wang Le , Sun Zao , Dai Xiaoyong , Zhang Yixin , Hu Hai-hua 
Published: August 2019

Purpose
The purpose of this paper is to facilitate understanding of how to mitigate the privacy concerns of users who have experienced privacy invasions.

Design/methodology/approach
Drawing on the communication privacy management theory, the authors developed a model suggesting that privacy concerns form through a cognitive process involving threat-coping appraisals, institutional privacy assurances and privacy experiences. The model was tested using data from an empirical survey with 913 randomly selected social media users.

Findings
Privacy concerns are jointly determined by perceived privacy risks and privacy self-efficacy. The perceived effectiveness of institutional privacy assurances in terms of established privacy policies and privacy protection technology influences the perceptions of privacy risks and privacy self-efficacy. More specifically, privacy invasion experiences are negatively associated with the perceived effectiveness of institutional privacy assurances.

Research limitations/implications
Privacy concerns are conceptualized as general concerns that reflect an individual’s worry about the possible loss of private information. The specific types of private information were not differentiated.

Originality/value
This paper is among the first to clarify the specific mechanisms through which privacy invasion experiences influence privacy concerns. Privacy concerns have long been viewed as resulting from individual actions. The study contributes to literature by linking privacy concerns with institutional privacy practice.
Experimental study on effect of fiber length and fiber content on tensile and flexural properties of bamboo fiber/epoxy composite
Authors: R. Giridharan , V.S. Raatan , M.P. Jenarthanan 
Published: August 2019

Purpose
The purpose of this paper is to study the effects of fiber length and content on properties of E-glass and bamboo fiber reinforced epoxy resin matrices. Experiments are carried out as per ASTM standards to find the mechanical properties. Further, fractured surface of the specimen is subjected to morphological study.

Design/methodology/approach
Composite samples were prepared according to ASTM standards and were subjected to tensile and flexural loads. The fractured surfaces of the specimens were examined directly under scanning electron microscope.

Findings
From the experiment, it was found that the main factors that influence the properties of composite are fiber length and content. The optimum fiber length and weight ratio are 15 mm and 16 percent, respectively, for bamboo fiber/epoxy composite. Hence, the prediction of optimum fiber length and content becomes important, so that composite can be prepared with best mechanical properties. The investigation revealed the suitability of bamboo fiber as an effective reinforcement in epoxy matrix.

Practical implications
As bamboo fibers are biodegradable, recyclable, light weight and so on, their applications are numerous. They are widely used in automotive components, aerospace parts, sporting goods and building industry. With this scenario, the obtained result of bamboo fiber reinforced composites is not ignorable and could be of potential use, since it leads to harnessing of available natural fibers and their composites rather than synthetic fibers.

Originality/value
This work enlists the effect of fiber length and fiber content on tensile and flexural properties of bamboo fiber/epoxy composite, which has not been attempted so far.

Authors: Zhang Xuepeng , Yang Kaiying , Chen Siyuan , Ji Yi 
Published: August 2019

AbstractKaposiform hemangioendothelioma (KHE) and tufted angioma (TA) are rare infiltrative vascular tumors. Currently, no standard treatment regimens exist for KHE/TA. The purpose of our study was to evaluate the efficacy and safety of topical application of tacrolimus for superficial KHE/TA. We examined six patients with superficial KHE/TA. All patients were treated with tacrolimus 0.1% ointment twice daily for at least 12 months. The response rate was 100%, including three nearly complete remissions. Only one patient experienced local pruritus during treatment. The data constituted an intriguing rationale for clinical trials of topical tacrolimus in the treatment of superficial KHE/TA.

Abstract

Expression of herbivore defense traits can change dramatically during the course of plant development. Little is known, however, about the degree of genetic or sexual variation in these ontogenetic defense trajectories or whether the trajectories themselves are adaptive, especially in long‐lived species.

We used a 13‐year dataset of chemical defense traits, growth and survivorship from a common garden of trembling aspen (Populus tremuloides) genotypes to document long‐term defense trajectories and their relationship to tree fitness during juvenile and early mature stages.

Overall, concentrations of the two principal classes of aspen defense compounds (salicinoid phenolic glycosides [SPGs] and condensed tannins [CTs]) decreased to differing degrees in foliage of juvenile trees and then remained relatively constant in maturity. Initial values, juvenile rates of change and average mature values all exhibited significant genetic variation for both SPGs and CTs.

Relationships between defense trajectory parameters and metrics of tree fitness (growth and survivorship) depended on compound type and tree sex. Females with higher‐allocation SPG trajectories (high initial juvenile concentrations, slow juvenile declines, high mature concentrations) grew more slowly relative to females with lower‐allocation trajectories. In males, higher‐allocation SPG trajectories had a lesser effect on growth but were associated with reduced mortality. Juvenile CT trajectories were not correlated with tree fitness, but average CT concentration in maturity was positively related to growth in females.

These results suggest that ontogenetic defense trajectories are adaptive and subject to natural selection. Genotypic variation and ontogeny shape tree defensive chemistry, both independently and interactively. These patterns of defense expression have the potential to structure trophic interactions and the genetic composition of forests in both space and time.

Behavioural fever reduces ranaviral infection in toads
Authors: Sauer Erin L. , Trejo Nadia , Hoverman Jason T. , Rohr Jason R. 
Published: August 2019

AbstractHost behaviour is known to influence disease dynamics. Additionally, hosts often change their behaviours in response to pathogen detection to resist and avoid disease. The capacity of wildlife populations to respond to pathogens using behavioural plasticity is critical for reducing the impacts of disease outbreaks. However, there is limited information regarding the ability of ectothermic vertebrates to resist diseases via behavioural plasticity.Here, we experimentally examine the effect of host behaviour on ranaviral infections, which affect at least 175 species of ectothermic vertebrates. We placed metamorphic (temporal block 1) or adult (block 2) southern toads (Anaxyrus terrestris) in thermal gradients, tested their temperature preferences before and after oral inoculation by measuring individual‐level body temperature over time, and measured ranaviral loads of viral‐exposed individuals.We found significant individual‐level variation in temperature preference and evidence for behavioural fever in both metamorphic and adultA. terrestrisduring the first 2 days after exposure. Additionally, we found that individual‐level change in temperature preference was negatively correlated with ranaviral load and a better predictor of load than average temperature preference or maximum temperature reached by an individual. In other words, an increase in baseline temperature preference was more important than simply reaching an absolute temperature.These results suggest that behavioural fever is an effective mechanism for resisting ranaviral infections.A freePlain Language Summarycan be found within the Supporting Information of this article.
Measuring agricultural total factor productivity in China: pattern and drivers over the period of 1978‐2016
Authors: Sheng Yu , Tian Xiaohui , Qiao Weiqing , Peng Chao 
Published: August 2019

The Chinese agricultural sector has experienced a substantial increase in total output since dramatic reforms were introduced in 1978. This paper uses the index method to measure agricultural total factor productivity (TFP) for China’s crop and livestock industries, based on the gross output model from 1978 to 2016. We construct production accounts for the industries using input‐output relationships for the 26 main agricultural commodities and commodity groups, which account for over 90 per cent of the total agricultural inputs and outputs. The results show that China’s agricultural TFP grew at a rate of approximately 2.4 per cent a year before 2009, which is comparable to the main OECD countries and is double the world average. TFP growth accounts for approximately 40 per cent of output growth, suggesting that input growth was the main driver of output growth in the past. However, average productivity growth slowed down after 2009 though it has gradually recovered since 2012. The slowdown reflects the emerging challenges to existing farm production practices in Chinese agriculture, suggesting the need for further institutional reform.
Analysis of Luminescent Gunshot Residue (LGSR) on Different Types of Fabrics

Published: August 2019

AbstractThe collection of gunshot residue on fabric can be an arduous task due to the microscopic size of particles (blind collection) and sheddability of some fabrics. The introduction of luminescent markers and consequent formation of luminescent gunshot residue (LGSR) can facilitate this analysis. In this study, different fabrics were analyzed in order to verify the persistence of the LGSR on them, the possibility of collecting and analyzing particles by video spectral comparator (VSC) and SEM/EDS. Also, different colored fabrics were used as targets in order to investigate influence of fabric color on LGSR visualization. Furthermore, the influence of the fabric type in the distribution of the LGSR deposited around the projectile´s hole entrance was evaluated. The fabric sheddability did not alter collection of the particles or analysis. It was possible to observe and collect LGSR on all tested fabrics, even after the fabric had been shaken, or in colored fabrics.
Unpacking Genetic Risk Pathways for College Student Alcohol Consumption: The Mediating Role of Impulsivity
Authors: Ksinan Albert J. , Su Jinni , Aliev Fazil ,   Spit for Science Workgroup, Dick Danielle M. 
Published: August 2019

BackgroundThe period of college represents a particularly risky developmental stage with regard to alcohol use, as college students engage in more risky drinking behaviors than their noncollege peers, and such problematic alcohol use is associated with far‐reaching negative consequences. Existing findings from genome‐wide association studies (GWAS) indicate that alcohol consumption has a complex polygenic etiology. Currently, there is a lack of studies examining genetic risk for alcohol consumption using polygenic risk scores (PRS) in college samples. In this study, we examined whether alcohol‐specific and risky behavior–related PRS were longitudinally associated with alcohol consumption among college students and whether this effect might be partially mediated by impulsivity domains.MethodsThe sample included n = 2,385 European ancestry (EA) and n = 1,153 African ancestry (AA) college students assessed over the course of 4 years. To indicate genetic risk, 2 PRS were created based on recent large‐scale GWAS: alcohol consumption (Liu et al., 2019) —drinks per week (DPW)‐PRS and risky behaviors (Linnér et al., 2019) —RISK‐PRS. The main outcome was alcohol consumption, measured across 4 waves of follow‐up data. The UPPS‐P impulsivity subscales were examined as mediators of the genetic effect on alcohol consumption.ResultsThe results from structural equation modeling showed that among EA students, both DPW‐PRS and RISK‐PRS had significant positive effects on alcohol consumption above and beyond UPPS dimensions and control variables. RISK‐PRS explained larger portion of variance in alcohol consumption than DPW‐PRS. RISK‐PRS showed a significant indirect effect on alcohol consumption through sensation seeking and lack of perseverance; no significant indirect effect of DPW‐PRS was found. No significant association of either PRS or alcohol consumption was found for AA participants.ConclusionsThe current results found that PRS related to more broadly defined risky behaviors predicted alcohol consumption across college years and that this association was partially mediated via dimensions of impulsivity.

BackgroundDespite severe structural brain abnormalities within the frontocerebellar circuit (FCC), cerebellar metabolism studied with 18F‐2‐fluoro‐deoxy‐glucose–positron emission tomography (FDG‐PET) is relatively preserved in patients with alcohol use disorder (AUD). The compensatory role of the cerebellum has been explored mainly through fMRI examination of AUD patients with the preserved level of performance. The present study aims at examining cerebellar metabolism and its relationship with regional brain metabolism and neuropsychological functioning in AUD patients.MethodsThirty‐two recently detoxified AUD patients and 23 controls underwent an FDG‐PET examination at rest. Participants also performed a neuropsychological battery assessing executive functions, verbal memory, and ataxia.ResultsCompared to controls, AUD patients had higher glucose uptake in the cerebellar lobule VIII, in association with hypometabolism, notably in several nodes of the FCC. Cerebellar hypermetabolism correlated negatively with regional hypometabolism in the premotor and frontal cortices. This pattern of regional hypermetabolism and hypometabolism related to ataxia and working memory deficits.ConclusionsThese specific brain–behavior relationships do not fulfill the criteria for brain compensatory processes. Cerebellar hypermetabolism may rather reflect the involvement of different pathological mechanisms, leading to a maladaptive plasticity phenomenon within the FCC in AUD patients who are early in abstinence. Further studies are required to examine the contributions of structural and functional connectivity alterations in the cerebellar hypermetabolism and the changes in these pathological mechanisms with abstinence or relapse.
Institutional quality, investment efficiency, and the choice of public–private partnerships

Published: August 2019

AbstractWe examine a sample of 625 public–private partnership (PPP) firms from 1980 to 2015 that straddle nine countries with varying degrees of economic development and PPP markets. We find that the motivations of the firms that undertake PPP investments vary. While private sector firms in economies with low institutional quality choose to engage in PPPs to alleviate capital constraints attributed to underinvestment, those in economies with high institutional quality participate in PPPs to solve the problem of overinvestment due to an abundant cash flow. In the long run, the benefits of lower capital constraints through PPP investments are more pronounced in economies with high institutional quality.
Density is more important than predation risk for predicting growth and developmental outcomes in tadpoles of spotted tree frog, Litoria spenceri (Dubois 1984)

Published: August 2019

AbstractThe diverse benefits of group living include protection against predators through dilution effects and greater group vigilance. However, intraspecific aggregation can decrease developmental rates and survival in prey species. We investigated the impact on tadpole development and behaviour of the interaction between population density and predation risk. Spotted tree frog (Litoria spenceri: Hylidae, Dubois 1984) tadpoles were kept at one of three different densities (two tadpoles per litre, five tadpoles per litre or 10 tadpoles per litre) until metamorphosis in the presence or absence of predatory cues. We aimed to determine the influence of population density, predation and the interaction of both factors in determining growth rates in tadpoles. Tadpoles were measured weekly to assess growth and development and filmed to quantify differences in activity and feeding frequency between groups. Generally, tadpoles housed without predators had longer developmental periods when housed with a predator, but there was no effect on tail length or total length. There was no effect of either predation cues or density on percentage of individuals feeding or moving. Although the effects of the presence of predators alone may appear to be less than the effects of the presence of competitors, the prioritisation of competitiveness over predator avoidance may increase vulnerability of tadpoles to the lethal threat of predators. This is particularly important in species such as L. spenceri, which is at risk from introduced fish predators.
