FabElm_BarcodeDb: matK barcode database of legumes
Authors: Mishra Bharat Kumar , Chaudhary Sakshi , Yasin Jeshima Khan 
Published: January 2018

AbstractBackgroundDNA barcoding is an imperative implementation of chloroplast rbcL and matK regions exploited as standard molecular barcodes for species identification. MatK is highly conserved in plants and has been used extensively as a phylogenetic marker for classification of plants. In this study matK sequences of Leguminosae were retrieved for variant analysis and phylogentics. From online resources, maturase sequences were retrieved; redundant sequences and partials along with poor quality reads were filtered to compile 3639 complete non-redundant matK sequences and constructed into a database for ready reference. The database FabElm_BarcodeDb made available at app.bioelm.com was constructed using available sequence resources.ResultsThe chloroplast genome of plants contains matK gene of 1500 bp, positioned between intron of trnK associated in-group II intron splicing. Mitochondrial matR and genomic matN sequences were compared with chloroplast matK. These maturase sequences share regions of homology with chloroplast and mitochondrial regions and are expected to be regulated by miRNA in producing splice variants contributing to speciation.ConclusionBase substitution rates of nuclear maturase were comparable with mitochondrial maturase and are different from matK sequences. Hence, few identified species in this investigation were clustered with other tribes when analysed using matK. MatK is effective in resolving the species level variations as splicing contributes to speciation; but utilization of matK alone as a barcode marker for legumes is dubious, as it could not resolve some species identity.AbbreviationsInDelsInsertions and deletionsITSInternal transcribed spacermatKMaturase KrbcLRibulose-bisphosphate carboxylase gene
How food retailing changed in Turkey: spread of self-service technologies
Authors: Kazancoglu Ipek , Kursunluoglu Yarimoglu Emel 
Published: January 2018

Purpose
The purpose of this paper is to predict customers’ intentions to use self-checkouts based on the technology acceptance model (TAM).

Design/methodology/approach
The questionnaire consisted of constructs taken from the existing literature such as perceived ease of use (PEU), perceived usefulness (PU), behavioral intentions, technology anxiety (TA), perceived risk (PR), need for interaction (NI), and situational factors (SF). Before preparing the questionnaire, the focus group studies were organized to gain deeper insights regarding customers’ views about self-checkouts. Based on the results of the focus groups, some items in the constructs were adapted, and the questionnaire was generated. The field study was conducted via face-to-face survey with 500 customers chosen by stratified random sampling. Confirmatory factor analysis and structural equation modeling were used to validate the relationships hypothesized in the conceptual model among constructs.

Findings
Out of the 16 hypotheses, 10 were found to be significant. The hypotheses related to the effects of PR, PEU, PU, intentions, while the effects of NI on PU and intentions; the effects of SF on intentions were not accepted in the study. According to the findings, PEU, PU, and TA affected intentions whereas PR, NI, and SF did not.

Research limitations/implications
There were some limitations related to demographics, attitudes, SF, and actual usage of self-checkouts.

Practical implications
To avoid queues, retailers should install a sufficient number of user-friendly and simple interfaced self-checkouts with well-trained employees to encourage usage and reduce the perceived risk and anxiety.

Originality/value
The main contribution of this study was that the effects of different constructs were measured on Turkish customers’ intentions to use self-checkouts, which could be used in formulating marketing strategies as well as considering future research directions. The paper also provided additional insights into the effects of SF, TA, NI, and PR, all of which were added to the TAM in this study.

Authors: Ahmadi Ebrahim , Mosaferi Mohammad , Nikniaz Leila , Tabrizi Jafar Sadegh , Asghari Jafarabadi Mohammad , Safari Gholamhoseyn , Bargar Mina 
Published: January 2018

Purpose
The purpose of this paper is to investigate the quality of the frying oil used in restaurants, fast food establishments, and confectionary stores. The compliance of used frying oils with the quality standards as determined by the peroxide value (PV) and the total polar materials (TPMs) is investigated by analyzing 375 samples of oil.

Design/methodology/approach
The PV was measured according to the national standard procedure number 4179, while the TPM was determined using a Testo 270 cooking oil tester. Frying oils with a PV>5 mEq/kg and a TPM>25 percent were considered to be non-edible. For a comparison of groups, the Mann-Whitney and Spearman correlation tests were used, and p<0.05 was considered significant.

Findings
The maximum TPM and PV recorded for frying oils in fast food restaurants were 97.5 percent and 77.9 mEq/kg, respectively. The results also revealed that 60 percent of samples were non-edible according to the TPM, while 58.9 percent of the oil samples were non-edible because of the PV. TPM and PV correlated well with each other (r=0.99, p<0.001) and with oil replacement intervals (r=0.90, p<0.001). The relationship between the TPM and PV was stronger in the polynomial model than the linear model. The following equation was obtained: peroxide (mEq/kg oil)=0.0043 TPM2 (%)+0.1587 TPM (%)–0.6152.

Originality/value
Considering the current limitations in official supervision by health authority, on-site self-monitoring of the TPM using the Testo 270 cooking oil tester by sellers as a solution seems a new approach. Food stores, restaurants, and confectionary stores should be equipped with TPM analyzers to determine the quality of the frying oil and the timely replacement of non-edible oils.

Authors: Schnettler Berta , Sepúlveda Néstor , Bravo Silvana , Grunert Klaus G. , Hueche Clementina 
Published: January 2018

Purpose
The purpose of this paper is to explore the consumer acceptance of a functional meat processed product made with different meat sources, and to distinguish the existence of different market segments.

Design/methodology/approach
Non-probability sampling was used to recruit a sample of 411 consumers in Southern Chile, over the age of 18 and responsible for the purchase of meat products for their household.

Findings
Using a fractional factorial design for conjoint analysis, it was found in the total sample that the meat source of the meat processed product was more important than packaging, region of origin, price and the functional ingredient claim, with preference for lamb and pork meat processed products with omega-3. Two main segments were identified using a cluster analysis; these segments differed according to family size, presence and age of children, ethnic origin, general health interest, quality of diet and level of satisfaction with food-related life. The largest segment (56.0 percent) shows a high preference toward lamb meat processed product with dietary fiber and omega-3. The second (33.6 percent) preferred turkey meat processed product with antioxidants.

Practical implications
A differentiated marketing strategy with different meat sources and functional ingredients may give access to a large market share. People more willing to accept different functional ingredients in processed meat products may enjoy a better quality of life. The level of satisfaction with food-related life and quality of diet can be useful in explaining preferences for functional meat processed products.

Originality/value
This is the first study to evaluate consumer acceptance of a functional meat processed product made with three different meats and three different functional ingredient claims, which analyzed the relationship between acceptance, the consumer’s quality of diet and their level of satisfaction with food-related life.

Published: January 2018

PurposeEating patterns around the world have changed considerably, including food choices and preparation. One of these alterations in food consumption patterns is an increase in desire for fast-food consumption, which has been associated with poor diet quality. In order to analyze consumers’ food consumption behaviors, it is necessary to account for psychological factors (e.g. attitudes) that shape behaviors. Thus, the purpose of this paper is to explore influencing factors on the attitudes of consumers in Isfahan City toward fast-food consumption, so as to understand why consumers use fast-food despite widespread knowledge of the negative health consequences.Design/methodology/approachThe predominant paradigm of the present study was quantitative, in that it was a correlational survey. The population of this study consisted of consumers who lived in Isfahan city in June 2015. A total sample of 350 people was selected using convenience sampling. Data were collected through a face-to-face interview with the consumers using a researcher-made questionnaire. Analysis was conducted using SPSS (V20) and AMOS (V20) software and a set of correlation and differential tests.FindingsThe results revealed that “health consciousness” and “trust” are the main effective factors on the attitudes of the respondents. The results also revealed that the elder and married respondents have more positive attitudes toward fast-food consumption.Originality/valueIt is worth mentioning that fast-food has become an important part of the Iranian diet. These findings have both academic and policy implications. The results showed that the need for much more consumer education regarding fast-food and mass media could effectively be used. Further, the government should support and subsidize fast-food restaurants so that they may produce healthier food options.

Authors: Raut Rakesh , Kharat Manoj , Kamble Sheetal , Kumar Chandra Shekhar 
Published: January 2018

Purpose
The purpose of this paper is to efficiently assist the decision makers in evaluating and selecting the most appropriate third-party logistics (3PL) provider from environmental sustainability perspective using a two-phase model based on data envelopment analysis (DEA) and analytic network process (ANP).

Design/methodology/approach
The study uses an integrated approach of DEA and ANP as an evaluation and selection methodology to select an efficient and requisite 3PL. The integrated model is a sound technique for 3PL evaluation and selection. DEA effectively screens the maximally efficient 3PLs, whereas ANP easily performs the cumbersome process of weighting diverse criteria and ranks various alternatives according to their performance on the basis of these criteria. This study lists the prominent evaluation and selection criteria taking into consideration the environmental sustainability. Finally, a real-life industrial application is presented to demonstrate the proposed method.

Findings
The current research work is devoted to the emerging research topic of environmental sustainability in logistics industry and supply chain management. The results of study indicate that eco-efficient transportation and 3PLs lead better transportation planning, better inventory and warehouse management, lower inventory cost and sustainable supply chain operations. Also, the applied approach enables the decision makers to better understand the complex relationships of the relevant criteria in the decision-making process.

Research limitations/implications
This study does not investigate the relationships between environmental performances and differentiation advantage from the perspective of 3PLs. Also, sensitivity analysis is not performed.

Practical implications
The developed integrated model enables decision analysts to better understand the complete evaluation process of 3PL evaluation and selection considering environmental sustainability perspective. Furthermore, the developed approach provides a more flexible, simple, accurate, effective, and systematic decision support tool for 3PL evaluation and selection.

Originality/value
The current study is first of its kind to use the integrated approach in evaluation and selection of 3PLs from environmental sustainability perspective considering the inter-dependencies among the evaluation and selection criteria.
Quality improvement calls data mining: the case of the seven new quality tools
Authors: Tsironis Loukas K. 
Published: January 2018

Purpose
The purpose of this paper is to propose a way of implementing data mining (DM) techniques and algorithms to apply quality improvement (QI) approaches in order to resolve quality issues (Rokach and Maimon, 2006; Köksal et al., 2011; Kahraman and Yanik, 2016). The effectiveness of the proposed methodologies is demonstrated through their application results. The goal of this paper is to develop a DM system based on the seven new QI tools in order to discover useful knowledge, in the form of rules, that are hidden in a vast amount of data and to propose solutions and actions that will lead an organization to improve its quality through the evaluation of the results.

Design/methodology/approach
Four popular data-mining approaches (rough sets, association rules, classification rules and Bayesian networks) are applied on a set of 12,477 case records concerning vehicle damages. The set of rules and patterns that is produced by each algorithm is used as an input in order to dynamically form each of the seven new quality tools (QTs).

Findings
The proposed approach enables the creation of the QTs starting from the raw data and passing through the DM process.

Originality/value
The present paper proposes an innovative work concerning the formation of the seven new QTs of quality management using DM popular algorithms. The resulted seven DM QTs were used to identify patterns and understand, so they can lead even non-experts to draw useful conclusions and make decisions.
On the different forms of returns from moving average buy-sell trading rule in the stock market
Authors: Ren Louie , Ren Peter , Glasure Yong 
Published: January 2018

Purpose
The purpose of this paper is to examine three different forms of returns based on the price difference, percentage change, and difference in logarithm price from moving average buy-sell trading rule. Statistical linear correlation, the means of returns from buy/sell days, and the flexibility of long-term moving periods are examined.

Design/methodology/approach
Traditional linear correlations, pairwise student t-test, and ϕ coefficient for two binary buy/sell decision variables are studied from the simple block bootstrap (convenience) sampling from S&P, Dow Jones, and NASDAQ price indices from January 29, 1985 to January 6, 2016.

Findings
The authors find that different forms of returns from MA(1-50) are strongly linearly correlated via 150 simple block bootstrap (convenience) samples from S&P, Dow Jones, and NASDAQ price indices from January 29, 1985 to January 6, 2016. In other words, the price differences, the percentage returns, and logarithmic returns are exchangeable for returns from S&P, Dow Jones, and NASDAQ. The authors refute the claims from Metghalchi et al.’s (2005, 2011) papers and Brock et al.’s (1992) paper. The authors conclude that the market is efficient and investors cannot gain benefits from moving average technical trading rule. Lastly, the authors find that the decisions from MA(1-50) and MA(1-200) are highly correlated; therefore, the length of periods used in long-period moving average is flexible.

Originality/value
It is one of the first studies about different forms of returns, their conclusions on the market efficiency, and the flexibility of long-term moving period for moving average buy/sell technical rules.
How the public and public relations professionals interpret leadership in Spain
Authors: Moreno Angeles , Navarro Cristina , Alkazemi Mariam 
Published: January 2018

PurposeThe purpose of this paper is to compare the perspectives of public relations professionals against those of the general public in Spain with respect to which communications activities and organizational attributes are relevant to the leadership images of organizations, and what are the characteristics of effective leaders.Design/methodology/approachThis study combines data from the European Communication Monitor (ECM) with the results of a representative online survey carried out by the global market research company IPSOS.FindingsResults show that the general public sees TV interviews as well as TV advertising as communication tools with the biggest potential to shape the leadership image of organizations. When it comes to the attributes of effective leaders, communication professionals overestimate the role of an organization’s vision, while the population much more stresses basic attributes like leading by example and admitting mistakes. PR practitioners underestimate customer service and environmental responsibility and tend to favor more abstract attributes like innovation and CSR.Research limitations/implicationsThis paper touches only four sections of the ECM 2014/2015. Participant fatigue may have negatively impacted the quality of the data. A large sample of professionals was approached, but a much small number initiated and completed the online survey. The size of the sample of communication professionals makes it difficult to generalize the results. In addition, future research should extend the study to different groups of stakeholders, such as employees, investors, and suppliers.Practical implicationsWhile organizations face intensive pressure from evaluation by their stakeholders, discrepancies between the expectations of the general public in regard to leadership negatively affects the communicator’s work to position organizations in society, as well as CEOs and top executives as leaders. On this regards, getting closer to what the population expects will help to understand and improve leadership perceptions.Originality/valueVery little work has been done in Spain regarding to leadership in public relations or public relations professional’s perceptions about leadership. Most research published to date has focused on the leader’s position in the company, participation in management levels, types of responsibilities assumed and their relative influence and leadership style. Even fewer public relations studies have tried to identify the communication activities that are relevant to the leadership image of organizations and compare the perspectives of public relations professionals on leadership against those of the general public. This dearth of knowledge about stakeholder expectations negatively affects the communicator’s work to position organizations and executive leaders in society.
Transitional distribution dynamics of housing affordability in Australia, Canada and USA
Authors: Cheong Tsun Se , Li Jing 
Published: January 2018

Purpose
The main purpose of this paper is to explore the transitional dynamics of housing affordability indicators of major cities in three developed countries: the USA, Canada and Australia, in the period after the global financial crisis. As the global housing markets are more interconnected today, it is essential to investigate the demographic movement pattern and their impacts on housing market dynamics.

Design/methodology/approach
Based on the Markov transition matrix approach and the stochastic kernel technique, a newly established framework named the mobility probability plot (MPP) is adopted to investigate the city-level trends of housing affordability in the three countries during the period 2008-2015.

Findings
The results suggest that the transitional dynamics of the USA’s housing affordability trend saliently differs from those of Canada and Australia: in the USA, MPP results reveal that when the price-to-income (P/I) ratio is higher than 3.5 times, it has a high tendency of moving downward in the next period. In Australia, housing affordability tends to continue deteriorating when the P/I ratios are in the range from 8.0 to 8.6. In Canada, the MPP analysis indicates that the P/I ratios tend to increase further when the ratios are between 5.7 and 7.0, and within the range of 8.3-9.5.

Originality/value
This paper adopts an innovative approach to explore the city-level trends of housing affordability in the three developed countries during the period 2008-2015. The distribution dynamics approach has several virtues: first, this approach does not merely focus on the issue of housing affordability but also includes an analysis of the underlying housing affordability distribution. Second, it can clearly show the mobility of the city-level units in terms of the P/I change. Third, it can predict the proportion of the entities in different P/I ratio bands in a number of years ahead and even in the long run.
