AbstractBackgroundPlatform-specific error profiles necessitate confirmatory studies where predictions made on data generated using one technology are additionally verified by processing the same samples on an orthogonal technology. In disciplines that rely heavily on high-throughput data generation, such as genomics, reducing the impact of false positive and false negative rates in results is a top priority. However, verifying all predictions can be costly and redundant, and testing a subset of findings is often used to estimate the true error profile. To determine how to create subsets of predictions for validation that maximize inference of global error profiles, we developed Valection, a software program that implements multiple strategies for the selection of verification candidates.ResultsTo evaluate these selection strategies, we obtained 261 sets of somatic mutation calls from a single-nucleotide variant caller benchmarking challenge where 21 teams competed on whole-genome sequencing datasets of three computationally-simulated tumours. By using synthetic data, we had complete ground truth of the tumours’ mutations and, therefore, we were able to accurately determine how estimates from the selected subset of verification candidates compared to the complete prediction set. We found that selection strategy performance depends on several verification study characteristics. In particular the verification budget of the experiment (i.e. how many candidates can be selected) is shown to influence estimates.ConclusionsThe Valection framework is flexible, allowing for the implementation of additional selection algorithms in the future. Its applicability extends to any discipline that relies on experimental verification and will benefit from the optimization of verification candidate selection.

Published: January 2018

AbstractSingle-particle reconstruction (SPR) from electron microscopy images is widely used in structural biology, but lacks direct information on protein identity. To address this limitation, we developed a computational and analytical framework that reconstructs and co-aligns multiple proteins from 2D super-resolution fluorescence images. We demonstrate our method by generating multi-color 3D reconstructions of several proteins within the human centriole and procentriole, revealing their relative locations, dimensions and orientations.
The role of psychological empowerment in climate-protective consumer behaviour
Authors: Hartmann Patrick , Apaolaza Vanessa , D’Souza Clare 
Published: January 2018

PurposeThis paper aims to address the role of psychological empowerment in proenvironmental consumer behaviour, focussing on climate protection.Design/methodology/approachStudy 1 analyses the interaction of the effects of psychological empowerment and personal norms on two environmental behaviours with a sample of 600 individuals drawn form a representative online panel of the Australian population. Study 2 addresses the reinforcing influence of empowerment with a quasi-experimental design comparing 300 consumers of green electricity with 300 conventional electricity clients.FindingsPsychological empowerment moderates the effects of personal norms on climate-protective consumer behaviour in a value-belief-norm (VBN) framework. Personal norms have a stronger influence for consumers experiencing high psychological empowerment than for disempowered feeling consumers. Furthermore, psychological empowerment experienced as an outcome of actual proenvironmental behaviour mediates the relationship between prior climate protection and future climate-protective intentions.Research limitations/implicationsFuture research should focus on the experimental manipulation of psychological empowerment with communicational claims, studying how perceived empowerment can be enhanced.Practical implicationsTo promote climate friendly products and behaviours, marketers should use communication claims aimed at enhancing consumer’s subjective experience of empowerment.Social implicationsPublic policy aimed at climate protection should focus on consumer education increasing consumers’ awareness of their potential influence.Originality/valuePsychological empowerment has not been studied previously as either an antecedent or outcome of proenvironmental behaviour. This is the first study to show that psychological empowerment moderates normative influences on climate-protective consumer behaviour. This research further reveals a novel behavioural reinforcement process, in which psychological empowerment intervenes as a behavioural outcome as well as an antecedent of climate-protective consumer behaviour. Findings contribute to the development of the VBN framework as well as to the consumer-empowerment perspective on proenvironmental behaviour.
Motives for (non) practicing demotion
Authors: Verheyen Tanja , Guerry Marie-Anne 
Published: January 2018

Purpose
The purpose of this paper is to provide insights into the practice of demotion. This study aims to do so in two ways: first, by investigating Belgian HR professionals’ key motives for practicing and not practicing demotion and second, by examining the reasons why HR professionals choose for these specific motives.

Design/methodology/approach
The explanatory mixed methods design is used: survey data are analyzed through cluster analysis resulting in insights into the motives for practicing demotion. Follow-up qualitative focus group interviews provide an explanatory understanding of the motives for practicing and not practicing demotion.

Findings
Low employee performance, optimization of the organization, employer branding and career possibilities are motives for practicing demotion. Demotivation, salary issues, a taboo and a lack of vacancies are motives for not practicing demotion. A cultural change, walk the talk, carefully selected vocabulary and transparent communication could possibly counter the motives for not practicing demotion.

Research limitations/implications
The use of terminology such as “downward career twist” instead of “demotion” in some questions of the survey might have influenced the answers of the Belgian HR professionals. In a focus group, no matter how small, participants sometimes tend to give socially desirable answers under group pressure, and this could influence the accuracy. Moreover, the HR professionals often expressed their own opinions, which they clearly dissociate from the views of the organization.

Practical implications
Organizations need to explore alternatives to motivate their employees in general and in particular in case of a demotion. This can be emphasized through a demotion policy. However, these alternative ways to motivate are important as extrinsic motivators such as salary are not the only way to motivate employees.

Originality/value
Motives for practicing and not practicing demotion are to the authors’ best knowledge never studied from a recent, Belgian HR perspective. These motives are contextualized in organizational justice theory. This study contributes to the demotion literature by elaborating the list of motives for practicing and not practicing demotion.
Demographic diversity on boards and employer/employee relationship
Authors: Li Ji , Zhang Ying , Chen Silu , Jiang Wanxing , Wen Shanshan , Hu Yanghong 
Published: January 2018

PurposeThe purpose of this paper is to explore the relationship between demographic diversity on boards and employer/employee relationship (EER) and to test the moderating effect of contextual factors such as a firm’s financial situation.Design/methodology/approachThis paper analyzes data from over 1,000 publicly listed US firms and uses hierarchical regression.FindingsDemographic diversity on boards of a given firm, such as ethnic diversity and gender diversity, should have positive effects on EER, which can be considered as an important dimension of overall human resource management performance in a given firm. Contextual factors such as a firm’s financial situation should moderate the relationship between demographic diversity on boards and the EER.Originality/valueFirst, this research contributes to the current literature by showing that EER can be influenced by demographic diversity on boards, which further helps to highlight the beneficial effect of demographic diversity in top management team. Second, this study uncovers the moderating role of some contextual factors such as a firm’ financial situation. Third, this study also contributes to the corporate governance literature by studying the link between demographic diversity on boards and EER.
Development and retention of Generation Y employees: a conceptual framework
Authors: Naim Mohammad Faraz , Lenka Usha 
Published: January 2018

PurposeThe purpose of this paper is to present a conceptual framework of development, commitment, and retention of Generation Y employees.Design/methodology/approachBased on a review of existing literature and using social exchange and social constructivist approach, this study presents a conceptual framework with mentoring, strategic leadership, social media, and knowledge sharing as its key constructs to retain Generation Y employees.FindingsMentoring, strategic leadership, social media, and knowledge sharing have a great potential to foster competency development. Competency development is critical to evoke affective commitment of Generation Y employees, which in turn results in intention to stay forth.Research limitations/implicationsThe proposed conceptual framework should be empirically validated in the future research.Practical implicationsOrganisations should incorporate mentoring, strategic leadership, social media, and knowledge sharing into their talent management strategy for Generation Y employees. Competency development then in turn evokes commitment of Generation Y employees, leading to intention to stay forth. The framework suggests an approach for generation-specific retention strategy.Originality/valueThis is one of the first studies to propose a holistic framework to retain Generation Y employees. This paper adds a new dimension to the talent management literature by focusing on young generation employees.
From “manager” to “strategist”
Authors: Dillen Yannick , Laveren Eddy , Martens Rudy , De Vocht Sven , Van Imschoot Eric 
Published: January 2018

PurposeFew high-growth firms (HGFs) are able to maintain high-growth over time. The purpose of this paper is to find out why only a small number of firms become persistent HGFs, explicitly focusing on the role of the founding entrepreneur in this process.Design/methodology/approachInitially, 28 semi-structured interviews were performed with high-growth entrepreneurs to discover why so few founders could become persistent high-growth entrepreneurs. In a second phase, four case studies were conducted to uncover the factors that facilitate a swift evolution from the “managerial” role to the “strategic” role.FindingsHigh-growth entrepreneurs, who quickly make a transition from a managerial role into a strategic role are more likely to keep their firm on its high-growth trajectory. This transition is made possible by: the early development of strategic skills; the presence of a high quality human capital base; and an organizational structure with characteristics from Mintzberg’s “machine bureaucracy.”Practical implicationsThe results are vital for entrepreneurs of “one-shot” HGFs with the ambition to make their firm a “persistent” HGF. If high-growth rates are to be sustained, the three factors that emerged from the authors’ analysis should foster the delegation of managerial tasks, resulting in an easier transition toward a “strategic role.”Originality/valueInsights are valuable as both founders and governmental institutions can benefit from knowing which factors contribute to a successful phase transition from “manager” to “strategist.”
Investigating teachers’ and school principals’ enactments of national testing policies
Authors: Gunnulfsen Ann Elisabeth , Roe Astrid 
Published: January 2018

PurposeThe purpose of this paper is to examine teachers’ reported experiences, practices, and attitudes on the use of national test results in a low-stakes accountability context. Whether the stakes are high or low, teachers and school leaders have different experiences, knowledge, and beliefs concerning how to use national test results to benefit individual student learning. This paper addresses how teachers experience school leadership and policy requirements for using national test results in local schools.Design/methodology/approachThis paper is part of a larger study conducted in a Norwegian educational context investigating school leaders’ and teachers’ enactments of policy demands via the use of national test results data. The sub-study reported in this paper is based on survey data from all lower secondary teachers (n=176) in one Norwegian municipality. Micro-policy perspectives and the concept of crafting policy coherence served as analytical tools.FindingsDiversity between the schools was found in how teachers perceive the principals’ role. Practices and attitudes appeared restrained, somewhat conformed by, but still indifferent to the policy intention. However, there was a close relationship between the principals’ facilitation of national tests and the teachers’ practices of utilizing the results.Originality/valueThis study clarified how micro-policy works in local schools in a low-stakes context. A prominent difference was found between the policy intentions and local schools’ practice of using national test results.
The anatomy of the inconspicuous luxury fashion experience
Authors: Makkar Marian , Yap Sheau-Fen 
Published: January 2018

Purpose
The purpose of this paper is to address the following questions: how do consumers construct meaning around their inconspicuous luxury fashion experiences? What desires do inconspicuous consumers strive to fulfill? What sentiments do they associate with their inconspicuous luxury fashion consumption?

Design/methodology/approach
This exploratory research begins with a netnographic study of 11 online luxury blogs followed by in-depth interviews and home observations of ten luxury consumers with inconspicuous preferences in Dubai.

Findings
Inconspicuous choices are not simply for associative or dissociative motivations but several symbolic consumption schemas come into play. A typology of inconspicuous luxury fashion consumers has emerged: fashion influencers, trendsetters, fashion followers, and luxe conservatives.

Practical implications
The findings have potential to yield important managerial implications for fashion retailers and brand communications. The typology of inconspicuous consumers provides a basis for developing a more targeted relationship marketing program for luxury fashion brands.

Originality/value
This research advances luxury knowledge in fashion and consumer behavior research by unveiling how consumers construct meanings around their inconspicuous consumption. The typology developed in this study marks the starting point for further extensions to explore the complexities of inconspicuous luxury consumers, which are grounded in the roles they take on in society, how they plan their luxury consumption journey and how they eventually use these possessions for self-identification and communication to others.
Accessible luxury fashion brand building via fat discrimination
Authors: Aagerup Ulf 
Published: January 2018

Purpose
The purpose of this paper is to investigate if accessible luxury fashion brands discriminate overweight and obese consumers.

Design/methodology/approach
The physical sizes of garments are surveyed in-store and compared to the body sizes of the population. A gap analysis is carried out in order to determine whether the supply of clothes match the demand of each market segment.

Findings
The surveyed accessible luxury garments come in very small sizes compared to the individuals that make up the population.

Research limitations/implications
The survey is limited to London stores but the garment sizes are compared to the British population. It is therefore possible that the discrepancies between assortments and the population are in part attributable to geographic and demographic factors. The study’s results are, however, so strikingly clear that even if some of the effects were due to extraneous variables, it would be hard to disregard the poor match between overweight and obese women and the clothes offered to them.

Practical implications
For symbolic/expressive brands that are conspicuously consumed, that narrowly target distinct and homogenous groups of people in industries where elitist practices are acceptable, companies can build brands via customer rejection.

Social implications
The results highlight ongoing discrimination of overweight and obese fashion consumers.

Originality/value
The study is the first to provide quantitative evidence for brand building via customer rejection, and it delineates under which conditions this may occur. This extends the theory of typical user imagery.
Consumer expenditures on clothing and footwear: a mixed methods study
Authors: Cruz-Cárdenas Jorge , Arévalo-Chávez Patricio , Guadalupe Jorge 
Published: January 2018

Purpose
The purpose of this paper is to establish the predictors of consumers’ annual monetary expenditures on clothing and footwear in Quito, the capital of Ecuador, a developing Latin American country.

Design/methodology/approach
The research followed an exploratory, sequential, mixed methods design. The first phase consisted of in-depth interviews with adult individuals. The second phase involved surveying a similar segment of the population.

Findings
The present study supports the importance of demographic and psychological factors as predictors. The study also identifies two new groups of predictors: consumers’ reception of used clothing and physical space at home and its management.

Practical implications
In addition to demographic variables, consumer panels that measure expenditures on clothing and footwear should include psychological measures of participants, particularly clothing involvement. Clothing manufacturers and retailers in developing countries should consider the impact of receiving used clothes by consumers. Because clothing buying and disposal behaviors are positively associated, companies should become more involved in their customers’ disposal behavior.

Originality/value
The contribution of the present study is twofold. First, it contributes to the understanding of clothing and footwear expenditures by considering the individual consumer as a unit of analysis. Furthermore, it provides insights into this behavior from a little-studied context.

Findings
The results of the current study revealed that there is a significant impact of hotels’ advertisement and hotels’ direct sale on hotel performance, whereas hotels’ website has no significant impact.

Originality/value
This is the first study that examines the effect of promotional mix on hotel performance during the political and economical crises in the Middle East and clarifies the most important elements that affect the countries’ economy, especially those involved in political conflicts.
eVisa’s impacts on travel and tourism: the case of Turkey
Authors: Çakar Kadir , Kalbaska Nadzeya , Inanir Ali , Şahin Ören Tuba 
Published: January 2018

Purpose
The purpose of this study was to investigate eVisa applications. eVisa is a service that falls under eTourism, whose growing use can be attributed to its ability to simplify the process of obtaining a visa. The objectives of this study were twofold: to explore the eVisa experience of tourists who have previously visited Turkey by using the service and to analyse the perceptions of stakeholders who have contributed to eVisa.

Design/methodology/approach
The present research has utilised two methodologies within the context of qualitative research methods. Data were gathered from tourists by using reviews (n = 1690) and in-depth interviews key actors (n = 4), which represent consumers and contributors’ perspectives on the eVisa system, respectively. While consumers dictate the demand of the service, contributors control its supply. The contributors referenced herein are relevant eVisa stakeholders in Antalya.

Findings
The research findings revealed eVisa facilitation’s positive effects on a destination’s image and tourists’ intentions to revisit destinations compared to when they use traditional visa-obtaining processes. The research findings then present suitable data for destination managers and policymakers regarding eVisa facilitation, followed by this study’s conclusions and implications.

Research limitations/implications
eVisa facilitation can foster demand for travel and tourism while maintaining bureaucratic elements of the traditional visa procedure. From a psychological perspective, eVisa facilitation can positively affect travel motivation to certain destinations where eVisas are applicable, as well as positively influence intentions to revisit tourist destinations.

Originality/value
The originality and uniqueness of the present study lies in its contribution to the increasing recognition of the significance and positive impacts of eVisa facilitation on travel and tourism demand.
Intelligent agent technology
Authors: Alsetoohy Omar , Ayoun Baker 
Published: January 2018

Purpose
This paper aims to empirically investigate the influence of the intelligent agent technology (IAT) on hotels’ food procurement practices (FPPRs) and food procurement performance (FPP). The study also explores the influence of FPPR on FPP in hotels.

Design/methodology/approach
Data from a survey of managers at luxury hotels in Florida, which yielded an effective sample of 78, were subjected to partial least squares structural equation modeling analysis.

Findings
IAT usage has statistically significant positive effect on both FPPR and FPP. Additionally, the results indicated that PPR has a positive influence on FPP.

Research limitations/implications
The study provided academia with a comprehensive review of the prior research on IAT benefits in food supply chain management (FSCM) and a comprehensive explanation of how the hotel FPPR are being performed by IAT. It also offers industry and technology specific insights.

Practical implications
Hotel managers should pay more attention to IAT application regarding the FPPR, specifically gathering information, supplier contract, contacting, requisitioning and intelligence and analysis. Moreover, hotel managers should enhance their employees’ abilities to be technology-oriented to maximize IAT benefits in FPP.

Originality/value
The results represent an extension to the technological innovation literature of the hospitality industry to bridge the gap of IAT in hotel FP. The framework used in the study serves as a foundation for future research studies in the hospitality industry, in FSCM in particular.
