AbstractThe APETALA2/Ethylene Responsive Factor (AP2/ERF) gene family has been shown to play a crucial role in plant growth and development, stress responses and secondary metabolite biosynthesis. Nevertheless, little is known about the gene family in ginseng (Panax ginseng), an important traditional medicinal herb in Asia and North America. Here, we report the systematic analysis of the gene family present in ginseng using several transcriptomic databases. A total of 189 putativeAP2/ERFgenes, defined asPgERF001throughPgERF189. The 93PgERFgenes that have the complete AP2 domain in their open reading frames were classified into five subfamilies, DREB, ERF, AP2, RAV and Soloist. The DREB subfamily and ERF subfamily were further clustered four and six groups, respectively, compared to the 12 groups of these subfamilies found in Arabidopsis. Gene ontology categorized these 397 transcripts of the 189PgERFgenes into eight functional subcategories, suggesting their functional differentiation and they have been especially enriched for the nucleic acid binding transcription factor activity subcategory. The expression activity and networks of the 397PgERFtranscripts have substantially diversified across tissues, developmental stages and genotypes. Then, the expression change of sixPgERFgenes randomly selected from DREB subfamily, i.e.,PgERF073,PgERF079,PgERF110,PgERF115,PgERF120andPgERF128responding to cold stress suggesting that DREB subfamily genes played an important role in cold resistance of ginseng. Finally, we studied the responses of thePgERFgenes to methyl jasmonate (MeJA). 288 (72.5%) of the 397PgERFgene transcripts responded to the MeJA treatment, with 136 up-regulated and 152 down-regulated, indicating that most members of thePgERFgene family are responsive to MeJA. These results provide resources and knowledge necessary for family-wide functional analysis of thePgERFgenes in ginseng and related species.
Customer in-role and extra-role behaviours in a retail setting
Authors: Paulssen Marcel , Brunneder Johanna , Sommerfeld Angela 
Published: November 2019

PurposePrior research does not provide a clear picture of how managers can effectively manage customer in-role and extra-role behaviours in a retail setting. This study aims to test the differential impact of the two main customer relationship predictor paths – identity-based and satisfaction-based paths – on customer in-role and extra-role behaviours.Design/methodology/approachA random sample of 500 customers from the flagship store of an up-market, international department store chain participated in a written survey. Purchase spending data for each customer was obtained from the retailer’s loyalty card database.FindingsThe two studied predictor paths possess a differential impact on customer extra-role behaviours. Civic virtue and co-creation behaviours are exclusively driven by the identity-based path, whereas sportsmanship is driven solely by the satisfaction-based path. Moreover, the identity-based path impacts purchase behaviour only when symbolic purchase motivation is high. Overall satisfaction has no impact on purchase behaviour.Research limitations/implicationsIn some retailing contexts, extra-role behaviours such as co-creation or civic virtue might simply be irrelevant (e.g. discount chains).Practical implicationsManagers, who have the intention to stimulate customers to give constructive feedback on products or services, or to involve them in co-creation activities, are well advised to also invest in identity-based path activities.Originality/valueThis study is the first to empirically test the effects of customer identification and overall customer satisfaction on the various dimensions of customer in-role and extra-role behaviours. Customer extra-role behaviours should not be conceptualised as one global construct but should comprise distinct dimensions of discretionary behaviours that have different antecedents.
Between appropriation and assassination
Authors: Murrey Amber 
Published: November 2019

PurposeOriented to ongoing student and university momentums for decolonial futures, the purpose of this paper is to interrogate the role and status of mainstream international development curricula and pedagogies by critiquing two absences in the sub-discipline’s teaching formulae: appropriations and assassinations.Design/methodology/approachThe author draws from a decade of research on oil extraction in Central Africa, including ethnographic work with two communities in Cameroon along the Chad–Cameroon Oil Pipeline; four years of research (interview-based and unofficial or grey materials) on the 1983 August Revolution in Burkina Faso and assassination of Thomas Sankara; and five years of experience teaching international development in North America, Western Europe and North and Eastern Africa.FindingsThrough a critical synthesis of political and rhetorical practices that are often considered in isolation (i.e. political assassinations and corporate appropriation of Indigenous knowledges), the author makes the case for what the author calls pedagogical disobedience: an anticipatory decolonial development curricula and praxis that is attentive to the simultaneity of violence and misappropriation within colonial operations of power (i.e. “coloniality of power” or “coloniality”).Originality/valueThis paper contributes to debates within international development about the future of the discipline given its neo-colonial and colonial constitutions and functions with a grounded attention to how this opens up possibilities for teaching praxis and scholarship in action.
Moderating effect of the digital divide of e-commerce
Authors: Sánchez-Torres Javier A. 
Published: November 2019

Purpose
The purpose of this paper is to examine whether the digital divide has a moderating effect on the technological factors that affect the adoption of electronic commerce.

Design/methodology/approach
This study proposes an exploratory empirical model that integrates the basic variables of e-commerce adoption through the use of the technology adoption model, making an extension with the facilitating conditions and the digital divide as a moderating variable. A digital survey was randomly distributed in Colombia, reaching a final sample of 745 electronic buyers.

Findings
The explanatory result validates that the perception of the digital divide negatively moderates the influence of the variables related to internet technology on the use of e-commerce.

Originality/value
This one of the first studies that analyzes the effect of the digital divide on the adoption of e-commerce.
Local corruption and local stock returns
Authors: Karadas Serkan , McAndrew William , Schlosky Minh Tam Tammy 
Published: November 2019

Purpose
The purpose of this study is to investigate the effect of corruption on stock returns in the USA. In particular, this study examines the relationship between corruption in a state (i.e. local corruption) and stock returns of firms headquartered in that state (i.e. local returns).

Design/methodology/approach
This paper uses the Fama–MacBeth two-step regressions. In the first step, the authors estimate the coefficients on the market, size, value and momentum factors for individual stocks. In the second step, they use those coefficients along with the corruption score of the state where stocks are headquartered to explain stock returns.

Findings
This paper finds that corruption in a state adversely affects stock returns of firms headquartered in that state. It further documents that the effect of corruption on stock returns is limited to geographically concentrated firms.

Originality/value
To the best of the authors’ knowledge, this paper is the first to document the effect of state-level corruption on individual stock returns in the USA using the Fama–MacBeth regressions. This study contributes to the literature by documenting the effect of local corruption on local stock returns in a low corruption country.
Differentiating risk factors of Ponzi from non-Ponzi frauds
Authors: Raval Vasant , Raval Vivek 
Published: November 2019

Purpose
This paper aims to analyze the attributes of Ponzi schemes (“Ponzis”) to determine whether they are a unique class of financial fraud.

Design/methodology/approach
The authors apply the disposition-based fraud model to classify and differentiate the attributes of Ponzis. This classification exercise helps comprehend the distinct drivers of Ponzis.

Findings
Fraud risk factors of Ponzis are different from those involved in other financial frauds. Four propositions about risk and risk mitigation measures are developed.

Research limitations/implications
The research approach used is conceptual, not empirical. However, the insights from this exercise should inform how different Ponzis are from other financial frauds and why they should be treated as a separate class for prevention and enforcement. In turn, this may trigger an interest in empirical research focused on the unique risks of Ponzis.

Practical implications
Knowledge of risk factors unique to Ponzis will permit a consideration of customized risk mitigation measures to prevent or detect Ponzis. Enforcement actions can also become more effective because of a distinct risk-based classification of Ponzis.

Social implications
The prevention of damage from Ponzis hinges upon how well prospective victims are educated to become aware of signs of Ponzis. This should lead to the more effective protection of investors from victimization from Ponzi schemes.

Originality/value
The implicit understanding that all financial frauds are alike and that the risk-factors involved are substantially the same across all classes of fraud is challenged. This revelation opens opportunities to add value through focused research on Ponzis as a distinct class of fraud.
Effect of blockchain technology adoption on supply chain adaptability, agility, alignment and performance
Authors: Sheel Ashutosh , Nath Vishnu 
Published: November 2019

Purpose
The purpose of this paper is to illustrate how blockchain technology can improve supply chain adaptability, alignment and agility which collectively enhance competitive advantage which in turn influences firm performance.

Design/methodology/approach
The conceptual framework of the present study is developed by conducting an extensive literature review on blockchain technology, supply chain adaptability, alignment, agility and competitive advantage. The sample data were collected from 397 supply chain practitioners in India to validate the conceptual model. Confirmatory factor analysis was conducted to ascertain the validity of the measures used and a structural model was analyzed for testing the proposed conceptual framework.

Findings
The results of the present study show that blockchain technology can improve supply chain adaptability, alignment, agility which lead to competitive advantage, which leads to better firm performance. Besides, trust generated through blockchain use also increases firm performance.

Research limitations/implications
Currently, the respondents do not have practical experience of using blockchain technology. They have responded based on their knowledge about supply chain and blockchain which they acquired from published sources. Different supply chains require different strategic choices and different information needs. But the present study assumes that all supply chain needs are identical. The present study assumes that government regulations regarding blockchain technology are favorable; however, currently, there is no legal framework to address blockchain technology. The findings of the current study indicate that companies not only should create more awareness regarding blockchain but also should actively work with IT companies that are engaged in developing blockchain-based supply chain solution. Managers, as well as IT companies and academicians, should join hands to study and develop a framework for regulating blockchain technology and suggest these to the policy actors.

Practical implications
The present study shows that supply chain practitioners are confident that blockchain technology will help improve supply chain parameters. These findings can help IT companies and their marketers for developing and promoting blockchain-based IT applications. In addition, the important implication for supply chain practitioners is that blockchain helps in creating a competitive advantage and increases firm performance.

Originality/value
The effect of IT on important supply chain variables has been studied in the past; however, there is not a single study which sheds light on how disruptive technologies such as blockchain will affect supply chain adaptability, alignment, agility and firm performance.
Pollination by bats enhances both quality and yield of a major cash crop in Mexico

Published: November 2019

Abstract

Bats pollinate many plants of high socio‐economic value, including the majority of columnar cacti (Cactaceae) in Mexico, which have been used by humans for food and materials for thousands of years. However, the importance of bats as pollinators has been overlooked, with a consequent lack of knowledge of the reliance of crops on bats for harvest yield and quality.

We used exclusion experiments to determine the effect of different pollinator taxa on the yield and quality of pitayas (fruit of Stenocereus queretaroensis (F.A.C. Weber) Buxbaum), a major crop in central Mexico. We studied the three most economically important cultivars and wild individuals in the principal region for pitaya production. For each pollinator taxon we recorded fruit set and measured three key parameters of fruit quality: weight, sucrose concentration and seed set. We placed camera traps to determine pollinator identity and the effect of visitation rate on fruit quality.

We found the primary pollinators of pitayas to be nectarivorous bats in the genus Leptonycteris. When bats were excluded from flowers and flowers were pollinated by other taxa (i.e. diurnal birds and insects), pitaya yield decreased by 35%, though pollination dependence varied between cultivars. Fruit quality decreased significantly in the absence of bat pollination across all cultivars, with fruits 46% lighter and 13% less sweet when pollinated by other taxa; reducing economic value, as size determines market price. Additionally, seed set (an indicator of effective pollination) was significantly lower in the absence of bat pollinators. Visitation rate had no effect on fruit quality.

Synthesis and applications. Our study shows that bats provide a vital ecosystem service by pollinating a crop of major socio‐economic importance, and that consideration of both crop quality and yield are essential to fully understanding the benefits of bat pollination. A reduction of this service would result in a decrease in both the size and quality of the harvest, causing substantial loss of income for rural communities. Bats world‐wide face many threats, and management efforts targeted to the enhancement of wild bat pollinator populations would preserve the sustainability of both bat‐pollinated crops and wild plants.
Multiple Copularization in Sogdian and Yaghnobi
Authors: Benkato Adam 
Published: November 2019

AbstractThe aim of this paper is to analyse the copula systems of Sogdian, an extinct Middle Iranian language, and Yaghnobi, a modern eastern Iranian language. It argues that Sogdian has one copula for the relations of existence, location, and possession, and develops three new, distinct copulas for identification and attribution. It also argues that the Yaghnobi system is similar, with a copula for existence and possession and two copulas for identification, attribution, and location. This paper suggests that the innovated Sogdian forms resulted from the combination of pronouns with the existential verb, with a possible distinction in their syntax based on the deixis of the copularizing pronouns. Finally, it shows that the large number of copula forms in Sogdian result from the re‐analysis of the copulas as verbal stems.

ObjectivesTo describe the population of women having bariatric surgery and compare the pregnancy outcomes for women having bariatric surgery with a non‐bariatric surgery population having a first and second pregnancy.DesignPopulation‐based record linkage study.SettingNew South Wales (NSW), Australia.PopulationAll women aged 15–45 years with a hospital record in NSW (2002–2014) and all women giving birth in NSW (1994–2015; n = 1 606 737 women).MethodsPregnancy and birth outcomes were compared between first and second pregnancies using repeated‐measures logistic regression and paired Student’s t‐tests. Bariatric and non‐bariatric groups were also compared.Main outcome measuresMaternal diabetes, preterm birth (<37 weeks of gestation) and large for gestational age.ResultsThere was a 13‐fold increase in hospitalisations for primary bariatric surgery during 2002–2014. Compared with the general birthing population, women who had bariatric surgery experienced higher rates of hypertension, diabetes, and preterm birth. Among women who had bariatric surgery between a first and second pregnancy, there were reduced rates of hypertension (OR 0.39, 95% CI 0.29–0.53), spontaneous preterm birth (OR 0.37, 95% CI 0.16–0.86), infants that were large for gestational age (OR 0.63, 95% CI 0.44–0.88), and the admission of infants to a special care nursery or neonatal intensive care (OR 0.64, 95% CI 0.46–0.90) in the second pregnancy. Rates for small‐for‐gestational age and gestational diabetes following surgery were 8.3 and 11.4%, respectivelyConclusionsBariatric surgery between a first and second pregnancy was associated with reductions in obesity‐related adverse pregnancy outcomes. Bariatric surgery performed for the management of obesity in accordance with current clinical criteria is associated with improved pregnancy outcomes in a subsequent pregnancy.Tweetable abstractBariatric surgery for obesity may improve pregnancy and birth outcomes in a subsequent pregnancy.

AbstractAimNutrition during pregnancy is fundamental to both the health of the mother and her baby. Sources of nutrition‐related information are available via many sources but their accuracy is unknown. The present study aimed to (a) identify where women source their nutrition information during pregnancy and (2) assess the accuracy of nutrition information for pregnancy that is available on the internet.MethodsA survey instrument that identified the main sources of nutrition information was administered to 68 pregnant women recruited online. Data from this survey were compared to previous similar surveys conducted with pregnant mothers across years 2008, 2011 and 2014. A content analysis of websites was simultaneously conducted to assess the accuracy of available information.ResultsThe main source of nutrition information for a variety of topics was verbal communication from health professionals (% responses affirmative for that source ranged from 6.6% to 69% across survey years). There was an increasing trend in internet sourced information for most nutrition topics, but this source remained low for iodine across all years (range: 7.3%‐15.9%). The internet was the main source of information for listeria/food safety (15.3%‐32.4%) and healthy eating (25%‐42%). Of the n = 165 websites identified by the content analysis, 82.4% (n = 136) were rated as accurate, with government (96.9%) and business/company (100%) sites having the highest accuracy.ConclusionVerbal communication from health professionals remains the most important source of nutrition information for pregnancy. The high credibility of websites indicates this to be an additional resource. Further study into health literacy levels among women visiting these sites is needed to assess impact on dietary behaviour.

AbstractAroma assessment remains difficult and uncertain in the present sensory assessment system. It is highly desirable to develop a new assessment method to discriminate the quality of various teas in the tea market. In the present work, based on linear discriminant analysis and principal component analysis, the aroma of dry and wet samples of different Xi‐hu Longjing and Pu‐erh teas were tested and differentiated by electronic noses (e‐nose). The results confirm that e‐nose can discriminate different priced Xi‐hu Longjing tea samples in the range of 80‐800 RMB/500 g and varying storage years of Pu‐erh tea samples. Furthermore, for the detection of both dry and wet samples of Longjing and Pu‐erh teas, the results reveal that all samples have specific aroma characteristics that e‐nose can recognize. More importantly, contribution analysis in sensors indicates that nitrogen oxides, methane and alcohols are the characteristic components that contribute to the fragrances of different priced Xi‐hu Longjing teas, while nitrogen oxides, aromatic benzene and amines make the fragrances of Pu‐erh teas with different storage years disparate.Practical ApplicationThis work demonstrates that e‐nose can rapidly distinguish tea products with different price levels and varying storage years. With the advantages of ease of use, high portability and flexibility, e‐nose will be widely expanded and applied in refined processing and the development of flavored foods.
