Quantitative Genetic Analysis of the Maize Leaf Microbiome
Authors: Wallace Jason G. , Kremling Karl A. , Buckler Edward S. 
Published: February 2018

AbstractThe degree to which an organism can affect its associated microbial communities (“microbiome”) varies by organism and habitat, and in many cases is unknown. We address this question by analyzing the metabolically active bacteria of the maize phyllosphere across 300 diverse maize lines growing in a common environment. We performed comprehensive heritability analysis for 49 community diversity metrics, 380 bacterial clades (individual operational taxonomic units and higher-level groupings), and 9042 predicted metagenomic functions. We find that only a few few bacterial clades (5) and diversity metrics (2) are significantly heritable, while a much larger number of metabolic functions (200) are. Many of these associations appear to be driven by the amount of Methylobacteria present in each sample, and we find significant enrichment for traits relating to short-chain carbon metabolism, secretion, and nitrotoluene degradation. Genome-wide association analysis identifies a small number of associated loci for these heritable traits, including two loci (on maize chromosomes 7 and 10) that affect a large number of traits even after correcting for correlations among traits. This work is among the most comprehensive analyses of the maize phyllosphere to date. Our results indicate that while most of the maize phyllosphere composition is driven by environmental factors and/or stochastic founder events, a subset of bacterial taxa and metabolic functions is nonetheless significantly impacted by host plant genetics. Additional work will be needed to identify the exact nature of these interactions and what effects they may have on the phenotype of host plants.
Impact of web banner advertising frequency on attitude
Authors: Hussain Rahim , Ferdous Ahmed Shahriar , Mort Gillian Sullivan 
Published: February 2018

PurposeThe purpose of this paper is to examine whether advertising type (static or dynamic) and appeal (emotional or rational) moderate the relationship between web banner advertising frequency and consumer attitudinal response.Design/methodology/approachA laboratory experiment involving 400 participants was conducted to test for the moderating effect. Factorial ANOVA is used to measure brand attitude.FindingsThe results identified that the web banner advertisement type acted as a moderator between frequency and brand attitude. However, the moderating effect of banner advertisement appeal was found to be insignificant at a single banner advertisement frequency (i.e. exposure) but significantly different at a higher frequency. The study findings provide better directives for online marketers.Practical implicationsThe major limitation is the fact that the impact of banner advertisement frequency was manipulated from one to five exposures. Future research needs to determine what happens after the fifth exposure, perhaps ten exposures or more, to determine the wear-out effect and in turn, to decide on the optimal frequency level in an effort to design more appropriate web communication strategies.Social implicationsThe result shows that pop-up banner advertisements are intrusive, and that high level of exposures to pop-up banner advertisement could annoy online users. Thus, online advertisers should avoid repeating the pop-up banner advertisements because this could adversely affect the attitude towards the online advertising in general, and could also negatively influence attitudes towards the brand and ultimately effect online purchase.Originality/valueThis study contributes to the theory by providing more insights into the repetition effect, and comprehensive conclusions can be drawn based on the manipulation of banner advertisement frequency on different frequency levels. The research identifies that if the communication objective is to generate brand attitude, different strategies can be adopted depending on the banner advertisement type (pop-up vs static) and banner advertisement appeal (emotional vs rational).
Exploring online and offline shopping motivational values in Malaysia
Authors: Wong Rachel Mei Ming , Wong Shiet Ching , Ke Guek Nee 
Published: February 2018

Purpose
The purpose of this paper is to combine the elaboration likelihood model and hedonic/utilitarian values into a coherent model of shopping motivational values for online and offline Malaysian shoppers. Once these values were identified, they were compared to one another based on shopping channel, gender, and age group.

Design/methodology/approach
The Shopping Motivational Value Questionnaire was developed by the researcher after extensive literature review and measured the respondent’s perception toward shopping motivational values in both shopping channels. Data were collected from 306 Malaysians above the age of 21, and analyzed using exploratory factor analysis and pairwise t-test techniques.

Findings
The factor analysis revealed a three-factor model of shopping motivational values. Gratification Values were the most important to shoppers, followed by Essential and Societal Values. Shoppers perceived all these motivational values as important when shopping offline as compared to online, regardless of gender and age group.

Research limitations/implications
The results of the factor analysis revealed a three-factor model of shopping motivational values: Gratification Values which were the most important to shoppers, followed by Essential and Societal Values. These values were then compared to one another based on shopping channel, gender, and age group. Results indicate that shoppers perceived all these motivational values as important when shopping offline rather than online, regardless of gender and age group. Moreover, the perception of shoppers toward specific product categories and other shopping channels were not taken into account.

Originality/value
This study attempted to combine the elaboration likelihood model and hedonic and utilitarian values into a coherent model. A questionnaire was developed by the researcher with these two theoretical models as its foundation. Additionally, the shopping motivational values of this study have been formulated to be compatible to both shopping channels.
Identifying the hidden layers of cultural changes and pinpointing the contributing factors of cultural changes using the casual layered analysis
Authors: Mohammadi Mohsen , Eivazi Mohammad Rahim , Reza Goudarzi Gholam , Keshavarz Turk Einollah 
Published: February 2018

Purpose
Various theoretical studies were carried out which attempted to identify impacting factors of cultural changes; however, these studies ignored the correlation among other affecting factors all together. In this paper, the authors aim not only to discuss the hidden layers that trigger the cultural changes but also to answer the questions of how to identify the main factors in each layer based on casual layered analysis (CLA), which could have a strong impact in shaping other layers’ factors? What are the dominant metaphors and worldviews that human beings are telling themselves about our universe that influences the future cultural changes?

Design/methodology/approach
To answer the questions of “how to identify the main factors in each layer,” the CLA methodology was used to investigate the underlying reasons. CLA takes into account four layers (litany, social systems, dominant discourse and worldviews and metaphors), which could be a tremendous help in identifying the mentioned factors.

Findings
The analysis shows that there are some contributing factors such as economy, technology, politics, society, environment, mass media, globalization and migration at the second layer – “social systems layer” – which may trigger cultural changes in first layer “litany”; in addition, in the third and deeper layer two dominant worldviews – materialist/secular and religious affecting the contributing factors in the second layer – were identified. Such worldviews are, in turn, supported by metaphors or perfect stories/myths of the deepest layer.

Originality/value
It can be concluded that because the cultural changes as a reality is composed of different layers, it is important to dig into different layers of reality to comprehend the significant shaping factors of that reality to visualize and make the better future.
Local community engagement in a festival in Indonesia
Authors: Sakitri Galih 
Published: February 2018

Purpose
The purpose of this paper is to identify the patterns of local community engagement in a festival held in Indonesia to boost tourism development.

Design/methodology/approach
The study uses in-depth interview and observation to answer the research problem.

Findings
The result reveals that the local community actively engaged in the festival, but not strategically or as per the planning process. The reasons were the local community’s lack of confidence and lack of ability.

Research limitations/implications
This research provides a case study of one festival area and the finding may not be applied generally.

Practical implications
The result indicates that the local government may encourage the local community by giving them motivation to raise their self-confidence and equipping them with training in basic principles of festival management. Then, the local government can engage them in the organizing committee. This would enable the local community to be strategically engaged in the festival.

Originality/value
This result identifies reasons for lack of local community engagement in an Indonesian festival.
Heritage in tourism organisations’ branding strategy: the case of a post-colonial, post-conflict and post-disaster destination
Authors: Seraphin Hugues , Yallop Anca C. , Capatîna Alexandru , Gowreesunkar Vanessa GB 
Published: February 2018

Purpose
The purpose of this study is to investigate the link between history (heritage) and tourism marketing (destination branding). More specifically, the paper focusses on how heritage is used by private- and public-sector tourism organisations of post-colonial, post-conflict and post-disaster (PCCD) destinations in their branding strategy. In particular, the paper investigates how these organisations use heritage in their branding and logo design.

Design/methodology/approach
Within the paradigm of theory building and exploratory approach, this conceptual study is based on a narrative literature review and analysis of research and secondary data on Haiti. The study uses visual research methods to examine and reveal the basis and composition of logos of both private- and public-sector organisations in Haiti.

Findings
The findings of this paper suggest that capturing the essence of the destination is critical for any visual identification (i.e. logos), and that the visual identification can either adjust representation of past events to the time being (heritage) or move away from the past with clear expectations for the future. Such findings are reflected within the new marketing strategies adopted by the Haitian destination marketing organisation (DMO) and a private resort that we used as examples. Both moved from an idiosyncratic identity-based logo to a universal “sea-and-sun” stereotyped one that goes against heritage for which authenticity is the most important criterion.

Practical implications
The findings of this research may help destination managers in general, and DMOs in PCCD destinations in particular, to design logos aligned with their marketing and branding strategies. The findings of the paper may also assist industry experts in designing logos that communicate with potential tourists, by leveraging heritage to influence their emotion and decision making.

Originality/value
This paper represents one of the first papers in tourism research that examines branding strategies of both public and private sectors in the context of Haiti. The research contributes to the body of knowledge on heritage and destination marketing by exploring the role of heritage in the Caribbean area’s branding and marketing strategies.
Exploration and exploitation within supply networks
Authors: Gualandris Jury , Legenvre Hervé , Kalchschmidt Matteo 
Published: February 2018

PurposeThe purpose of this paper is to introduce and define the concept of purchasing ambidexterity in terms of two dimensions: balance dimension and combined dimension. The study proceeds to empirically examine the multiple performance effects generated for the buying firm and its key suppliers.Design/methodology/approachAmbidexterity theory informs the authors’ conceptual model. To test the hypotheses, the authors collected survey data from 95 purchasing functions of medium and large European firms and applied various estimation techniques.FindingsThis research indicates that ambidexterity substantially varies across purchasing functions. Further, it discovers that a purchasing function’s ability to advance the combined magnitude of exploratory and exploitative activities represents an essential determinant of supplier efficiency, supplier product innovation, and buyer financial performance. Notably, this research also discovers that balancing the magnitudes of exploratory and exploitative activities on a relative basis produces negative effects on the innovativeness of the supply network.Originality/valueAlthough ambidexterity theory has been applied to supply chain management, limited attention has been dedicated to purchasing ambidexterity. This gap led us to study how purchasing impacts the competitiveness of the buying firm and of its supply network by balancing and combining exploratory and exploitative activities. This research is the first to advance the notion of purchasing ambidexterity, unpack its underlying dimensions, and examine its multiple performance implications. Such a conceptual and empirical development presents new perspectives on how purchasing can help the buying firm and its supply network to strengthen their competitiveness.
Supply chain integration, risk management and manufacturing flexibility
Authors: Chaudhuri Atanu , Boer Harry , Taran Yariv 
Published: February 2018

Purpose
The purpose of this paper is to investigate the impact of internal integration, external integration (EI), and supply chain risk management (SCRM) on manufacturing flexibility, and the moderating effect of SCRM on the relationships between internal and EI, respectively, and manufacturing flexibility.

Design/methodology/approach
Using hierarchical regression, data are analyzed from a sample of 343 manufacturing plants in Asia collected in 2013-2014 as part of the International Manufacturing Strategy Survey (IMSS VI).

Findings
Internal integration and SCRM have a direct effect on manufacturing flexibility. SCRM moderates the relationship between EI and flexibility.

Research limitations/implications
Further research is needed to generalize beyond the flexibility performance of discrete manufacturing firms in Asia.

Practical implications
To benefit from EI and increase their flexibility performance, manufacturing firms need to implement different mechanisms of SCRM to prevent and deal with supply chain risks including those associated with supply chain integration.

Originality/value
This research contributes to the body of knowledge on the relationships between internal integration, EI, SCRM, and manufacturing flexibility.
Missing performance management and measurement aspects in performance-based contracting
Authors: Glas Andreas H. , Henne Florian U. , Essig Michael 
Published: February 2018

PurposePerformance-based contracting (PBC) is a business model for the adaptive and innovative delivery of product-service systems. In PBC, the provider is paid according to the service performance with the aim of providing monetary incentives to safeguard possible outcomes as much as possible for the PBC customer. Performance measurement and its management are crucial for PBC success and, in particular, for the pay-for-performance link. However, the literature on PBC performance management is rather sparse, and there has been no systematic review on the topic. Thus, the purpose of this paper is to fill that gap and to present a comprehensive and systematic review of performance measurement and management in the PBC context.Design/methodology/approachThe paper builds on a literature review based on a sample of 102 subject-relevant articles from academic journals. The content analysis follows a two-step procedure. First, the articles are coded following a process-based research framework. Second, the content of each process step is assessed in a qualitative text analysis.FindingsThe results show a surprising scarcity of papers that explicitly address performance management topics in the context of PBC. Only the topics of performance specification and performance indicators are broadly addressed, whereas in all of the other areas, e.g., strategic alignment, data capture and reporting, only limited specific findings could be found.Research limitations/implicationsThe paper concludes that future research on performance management in PBC should expand its theoretical framework and empirical efforts in four specific proposed directions.Originality/valueThe paper provides an up-to-date review that is focused on performance management and measurement in the emerging context of PBC.

Published: February 2018

Purpose
Chiang Rai is the northernmost province of Thailand. Municipal solid wastes (MSWs) was generated 430,828.2 ton/y in this area; however, only 24 percent of waste was properly disposed, and 43 percent of waste was properly managed. The purpose of this paper is to explore knowledge, attitudes and practices (KAP) of highland residents in order to provide a basis for the development of waste management in the study area.

Design/methodology/approach
A cross-sectional study was conducted in Mae Fah Luang district, Thailand, from November 2016 to January 2017. A random sample of 451 respondents constituted the study population. Data were gathered using a structured questionnaire. Pearson Correlation and χ2 were applied to identify the association among variables.

Findings
Overall, 73 percent of respondents had high level of knowledge; 85 percent of respondents showed neutral attitude; and 59 percent of respondents performed moderate practice on MSW management. The results highlighted that age and education levels were statistically significant associated with KAP levels on MSW management at (p=0.05).

Originality/value
The respondents who have good knowledge also have a good level of practice; and those who have good attitude also have a good level of practice. Socio-demographic factors and suitable way to promote an effective MSW management should be considered.
New product selling challenges (key insights in the ICT sector)
Authors: Sharma Archana , Sagar Mahim 
Published: February 2018

PurposeThe purpose of this study is to identify crucial and new product selling challenges in the Information and Communication Technology (ICT) sector for the companies operating in Business to Business (B2B) sales setting.Design/methodology/approachThis study uses qualitative techniques of focus group discussion, semi-structure interviews and thematic content analysis to explore crucial and new product selling challenges. Total interpretive structuring modeling (TISM) is used to create a hierarchy amongst the factors and interpret the relationships amongst them.FindingsThis study identifies crucial challenges for the ICT sector. The TISM framework helped in identifying variables and explained the relationship between the identified variables.Research limitations/implicationsThe findings may have been affected by the small size of the sample, the research was restricted to Indian market only and the result would have varied across cultures and different domains.Practical implicationsCompanies in the ICT sector are eager to develop new products but fail to sell it. Salespeople play a crucial role in diffusing the new product in the market. Addressing the challenges faced by salespeople will improve not only the sales of the new product but also the overall the operational efficiency of the sales force.Social implicationsAlthough several studies have suggested that sales force is the major contributing factor to new product success, few studies have focused on the role of salespeople in new product launch, particularly with respect to challenges in new product selling.Originality/valueThis is the first study to identify new product selling challenges in the ICT sector.

Published: February 2018

AbstractA postmarketing surveillance study is ongoing to evaluate nivolumab treatment for Japanese patients with malignant melanoma and accumulate data on all adverse events (AE) and efficacy. In this interim analysis, we evaluated data from approximately 100 Japanese medical institutions obtained from the nivolumab approval date in Japan (4 July 2014) through 3 July 2016. Patients were monitored during the first 12 months of treatment. Nivolumab was administrated by i.v. infusion (2 mg/kg every 3 weeks). A total of 680 and 610 patients were evaluated for safety and efficacy, respectively. The incidences of adverse drug reactions (ADR) and grade 3 or higher ADR were 53.53% and 12.35%, respectively. Predominant ADR included hypothyroidism (11.32%) and abnormal enzyme activity, such as increase of aspartate aminotransferase (7.79%), alanine aminotransferase (6.76%), alkaline phosphatase (6.18%) and γ‐glutamyltransferase (5.44%). Grade 3 or higher ADR of special interest with an incidence of 1% or higher were hepatic function disorder (2.50%), colitis/diarrhea (2.06%) and infusion reaction (1.32%). No cases of encephalitis or venous thromboembolism, other AE of special interest, were observed. The estimated median overall survival was 379 days (95% confidence interval [CI], 290–not reached [NR]) in the overall population, NR (95% CI, 305–NR) for cutaneous melanoma and 340 days (95% CI, 275–NR) for mucosal melanoma. The improvement rate based on the antitumor response at the last evaluation was 22.2% (131/590 patients). No new safety concerns were raised, and serious ADR of special interest were infrequent. Nivolumab showed equivalent efficacy in patients with mucosal melanoma and those with cutaneous melanoma.
