Resource diversity structures aquatic bacterial communities
Authors: Muscarella Mario E. , Boot Claudia M. , Broeckling Corey D. , Lennon Jay T. 
Published: August 2018

ABSTRACTMicrobial diversity is strongly affected by the bottom-up effects of resource availability. However, because resource pools often exist as heterogeneous mixtures of distinct molecules, resource heterogeneity may also affect community diversity. To test this hypothesis, we surveyed bacterial communities in lakes that varied in resource concentration. In addition, we characterized resource heterogeneity in these lakes using an ecosystem metabolomics approach. Overall, resource concentration and resource heterogeneity affected bacterial resource-diversity relationships. We found strong relationships between bacterial alpha-diversity (richness and evenness) and resource concentration and richness, but richness and evenness responded in different ways. Likewise, we found associations between the composition of the bacterial community and both resource concentration and composition, but the relationship with resource composition was stronger. Last, in the surveyed communities the presence of resource generalists may have reduced the effect of resource heterogeneity on community composition. These results have implications for understanding the interactions between bacteria and organic matter and suggest that changes in organic matter composition may alter the structure and function of bacterial communities.
Effect of extrinsic cues on willingness to pay of wine
Authors: Lee Won Fy , Gartner William C. , Song Haiyan , Marlowe Byron , Choi Jong Woo , Jamiyansuren Bolormaa 
Published: August 2018

Purpose
The purpose of this paper is to examine the effect of extrinsic cues on wine consumer’s willingness to pay (WTP) based on a blind tasting experiment conducted in Hong Kong.

Design/methodology/approach
Using data from a three-stage blind wine tasting experiment, the authors examine how an average consumer’s WTP for a bottle of wine changes as a result of knowing prior to tasting extrinsic information such as the country of origin or grape variety of an otherwise identical product.

Findings
The findings of this study align with previous research that finds subjective utility experienced by tasters can be significantly influenced by the belief or information given prior to the tasting. Sub-group analysis using a stratified sample based on the frequency of wine consumption and the wine taster’s prior experience with wine (grouped into expert and novice categories) suggests that it is the novice consumers that have a stronger response to the pre-tasting knowledge when evaluating wine. Experienced wine consumers, on the other hand, do not seem to respond strongly to the pre-tasting knowledge of the extrinsic attributes in their evaluation of wine.

Originality/value
The studies of taste preference and role of extrinsic characteristics in wine evaluation and consumption in the rapidly growing Asian market is increasingly important for the wine industry. The evidence from this study suggests the importance for producers and marketers to consider consumer heterogeneity and product differentiation when pricing and distributing their wine.
Personal values underlying halal food consumption: evidence from Indonesia and Malaysia
Authors: Arsil Poppy , Tey Yeong Sheng , Brindal Mark , Phua Cun Uei , Liana Denisa 
Published: August 2018

Purpose
The purpose of this paper is to uncover the personal values driving Indonesian and Malaysian Muslims’ consumption decisions with respect to halal food.

Design/methodology/approach
The personal values of 130 Indonesian and 80 Malaysian Muslims have been analyzed, using a means-end chain (MEC) approach, in relation to halal food.

Findings
Primary personal values are identified as a better sense of personal security. This is ascribed as seeking “better future” and “go to heaven.” Other personal values are related to tradition, benevolence and achievement.

Research limitations/implications
Since this study was conducted in both the capital cities of Indonesia and Malaysia, this study might not take account of cultural diversity within the two countries’ Muslim communities.

Practical implications
An understanding of the personal values governing Muslim consumption is a useful tool toward improving the promotion of halal certification and food products.

Originality/value
This study reveals the personal values of Indonesian and Malaysian Muslims with underpinning their consumption of halal food.
Soft drinks for lunch? Self-control, intentions and social influences
Authors: Melbye Elisabeth Lind , Helland Merete Hagen 
Published: August 2018

Purpose
The purpose of this paper is to explore associations between food-related self-control, intentions, descriptive peer norms, parents’ healthy eating guidance and adolescents’ consumption of sugar-sweetened beverages (SSB) in a school lunch setting. An additional aim was to evaluate the psychometric properties of the measure used to assess food-related self-control in order to reveal potential multi-dimensionality.

Design/methodology/approach
A web-based survey was conducted among 694 Norwegian high school students. Multiple logistic regression was used to explore associations between the independent variables and SSB consumption. Psychometric evaluation of the self-control measure included factor analysis and internal consistency reliability.

Findings
Factor analysis resulted in two food-related self-control dimensions: resistance and avoidance. Multiple logistic regression showed that intentions was the strongest predictor of SSB consumption in the sample. Avoidance and descriptive peer norms appeared as weaker predictors.

Research limitations/implications
Based on the findings, the authors suggest that future studies may consider developing guiding principles on how to create health-promoting eating intentions in adolescents, how to deal with peer norms related to foods and beverages and how to avoid tempting stimuli in the environment. Such strategies may be helpful when structural changes in the environment are not feasible in the near future.

Originality/value
An original aspect of the present study is that it includes a psychometric analysis of a supposedly one-dimensional self-control measure. Further, it adds to the knowledge about variables associated with adolescent SSB consumption in a school lunch context.
Estimating factors for the demand of organic milk in Turkey
Authors: Gulseven Osman 
Published: August 2018

Purpose
The purpose of this paper is to identify the sociodemographic factors that affect Turkish consumers’ decision to purchase organic milk. It is also of interest to derive the demand curve for organic milk based on the consumers’ stated preferences.

Design/methodology/approach
The data used in this search are based on a face-to-face consumer survey that asked the respondents about how much they are willing to pay for organic milk and what factors affect their purchasing decision. A variant approach is applied where the determinants selected include both product/market characteristics and household-specific demographic factors. The data are analyzed by means of tabular analysis, summary tables, contingent valuation, stepwise regression, χ2 tests and logistic discrete-choice modeling.

Findings
The tabular analysis suggests that price, packaging and brand image are the primary milk characteristics that affect consumers’ decision. According to the contingent valuation analysis, consumers are willing to pay substantial premiums for milk products. The stepwise regression, χ2 tests and logistic regression results unanimously suggest that educational attainment is the only significant indicator. Households with university education are twice more likely to purchase organic milk.

Research limitations/implications
The data used in this research are based on stated preferences which might be different than actual shopping behavior.

Originality/value
This paper presents a pioneer study on the characteristics of Turkish organic milk consumers and represents a credible, empirical case study to complement existing literature. It also lays the framework for follow-up research work that can be conducted in future.
Socialization tactics and youth worker adjustment: the mediating roles of fit perceptions
Authors: Oh Seok-young 
Published: August 2018

PurposeThe purpose of this paper is to identify how three types of socialization tactics – content, context and social tactics – influence fit perceptions, and then how three types of fit perceptions – person–organization (P–O) fit, person–job (P–J) fit and person–group (P–G) fit – mediate the relationship between socialization tactics and positive socialization outcomes: organizational commitment, job satisfaction and intent to quit.Design/methodology/approachResponses from participants – 207 Korean youth workers – were subjected to ordinary least squares path analyses with bootstrapping to test the hypotheses.FindingsFirst, this study found that socialization tactics promote youth workers’ perceived fit with organization, job, and people. Then, the mediation model showed that content socialization tactics do not influence dependent variables (socialization outcomes) through mediators (fits), while context tactics influence through perceived P–O fit and P–G fit for organizational commitment only, and social tactics through perceived P–O, P–J and P–G fit for organizational commitment, job satisfaction and intent to quit.Research limitations/implicationsThe results of this study suggest that institutionalized social tactics can serve as a key socialization method for new employees. In addition, youth organizations need to implement jointly formal and collective training programs with follow-up social workplace learning (e.g. mentoring and study circle) to help newcomers share the values of the organization and integrate well into it.Originality/valueThis study contributes for understanding the socialization process of new employees working in educational and social work fields and role of fit perception between socialization tactics and their career successes.
Facilitating interns’ performance
Authors: van Wingerden Jessica , Derks Daantje , Bakker Arnold B. 
Published: August 2018

Purpose
The purpose of this paper is to report a study in which central propositions from the job demands-resources (JD-R) theory and self-determination theory (SDT) are used to examine the antecedents of performance during practical internships. The central hypothesis of this study was that job resources foster performance through basic need satisfaction and work engagement (sequential mediation).

Design/methodology/approach
An empirical multi-source study among Dutch interns and their supervisors in various occupational sectors. The interns reported their level of resources, basic needs satisfaction and work engagement, whereas supervisors rated interns’ task performance (n=1,188 unique supervisor–intern dyads).

Findings
This study integrates insights of the JD-R theory – by examining the relations between job resources, work engagement and performance – with a central premise of the SDT – which maintains that basic need satisfaction is the fundamental process through which employees’ optimal functioning can be understood. The outcomes of the path analyses revealed that satisfaction of needs indeed accounted for the relationship between job resources and work engagement as supposed in the SDT (Deci and Ryan, 2000). Further, the sequential mediated relation between job resources and performance through basic need satisfaction and work engagement corroborates the JD-R theory (Bakker and Demerouti, 2014).

Originality/value
As far as the authors know, this is the first study that examined the sequential mediation from job resources to performance via basic need satisfaction and work engagement, among a large sample of intern–supervisor dyads, including the objective performance rating of their (internship) supervisors.
The duality of the Brazilian jeitinho
Authors: Lee Park Camila , Fracarolli Nunes Mauro , Muratbekova-Touron Maral , Moatti Valérie 
Published: August 2018

Purpose
This paper aims to deepen the understanding of the impact of cultural and national idiosyncrasies on businesses. The authors concentrate on the cultural particularity of the Brazilian jeitinho to assess the ethicality of the concept in buyer–supplier relationships.

Design/methodology/approach
Semi-structured interviews were conducted with 28 Brazilian professionals working for both national and international companies, allowing for the analysis of the context in which the Brazilian jeitinho is perceived either as positive or negative in terms of ethics.

Findings
The authors propose five distinct dimensions (harm to third parties, seriousness of the issue, formality of relationships, personal benefit and assessed pertinence of rules and laws) to the assessment of Brazilian jeitinho as creativity, corruption or more nuanced classifications between them and offer a reviewed definition of the practice.

Practical implications
The results of the study may offer new insights into the Brazilian business environment. Deeper comprehension of the contexts in which jeitinho is used and its different connotations may optimise the relations between foreign and Brazilian companies and between foreign and Brazilian professionals and employees.

Originality/value
Within the context of intensified international trade, global supply chains and geographically spread operations, an understanding of cultural and national idiosyncrasies may provide managers with a powerful tool to conduct their business more effectively. With the economic emergence of countries such as China, Russia and Brazil, local practices are also gaining increased importance as they seem to have a direct influence on management in these places and beyond.
Factors influencing time allocation of sport event volunteers
Authors: Hallmann Kirstin , Downward Paul , Dickson Geoff 
Published: August 2018

Purpose
Given the increasing demands placed on a sport event workforce in servicing the needs of spectators, to attract and recruit volunteers to the industry, it is important for sport event managers to know what is driving how much time volunteers allocate to an event. The purpose of this paper is to investigate the individual and macro-level factors influencing the allocation of time to volunteer at sport events.

Design/methodology/approach
Survey data were collected from volunteers at 25 sport events (n=2,303). Multi-level modelling was used to identify common effects controlling for event differences.

Findings
Male gender significantly influences time allocated to an event at the individual level. At the macro-level, the number of local inhabitants has a significant negative effect whereas the status of an international event and duration contribute positively to time allocation.

Research limitations/implications
The results provide clear evidence that macro-level variables can stimulate interest in event volunteering opportunities.

Originality/value
This paper uses a multi-level approach to assess the influence of micro- and macro-level variables on time allocation by sport event volunteers. Using this approach, event heterogeneity can be controlled.
Examining the cross-cultural attitudes of Qataris and expatriates in Qatar, the host country of 2022 World Cup
Authors: Diop Abdoulaye , Al-Emadi Ahmed , Kaplanidou Kiki , Sagas Michael , Elmaghraby Engi , Qutteina Yara 
Published: August 2018

Purpose
The purpose of this paper is to examine how residents in Qatar, the host country of the 2022 World Cup, interact, socialize and acculturate in order to create a more harmonic society, a critical factor for the event delivery and preparations.

Design/methodology/approach
Data were collected from Qatari nationals and expatriates residing in the country of Qatar using a survey. A stratified random sampling approach was applied using as sampling framework all households having a mailing address with the country’s electric company. In total, 2,398 Qataris were contacted and 1,020 completed the survey. From the expatriate population, 1,852 were contacted and 1,134 completed the survey.

Findings
The results showed Qatari nationals were favorable toward Arab and Asian expatriates but not as favorable as Arab and Asian expatriates were toward them. Both groups of residents showed high quality of life (QOL) perceptions, with the locals having slightly higher QOL. Finally, Asian expatriates were more open to socializing with the locals and Arab expatriates.

Research limitations/implications
The results of the study shed light into the acculturation process in host societies of mega sport events such as the 2022 World Cup in Qatar.

Originality/value
This is the first study that examined a mega event’s host country resident’s cultural interactions to identify potential issues that can arise and interfere with the event experience of the 2022 World Cup in a very diverse society.
Understanding the inspiration among active participants in sport events
Authors: Zhou Ran , Kaplanidou Kyriaki , Papadimitriou Dimitra , Theodorakis Nicholas D. , Alexandris Kostantinos 
Published: August 2018

Purpose
The purpose of this paper is to explore the sources of inspiration for active participants in sport events, and the link between inspiration sources and event-related outcomes (i.e. life satisfaction and behavioral intentions).

Design/methodology/approach
Research questions were examined using a Greek (n=264) and a US (n=103) sample of participants of two small-scale running events. Content analysis was used to identify and code the themes of inspiration, while a multivariate analyses of variance was performed to test the inspiration group differences on life satisfaction and behavioral intentions.

Findings
The qualitative findings revealed three categories of inspiration source identified in each sample. The quantitative results showed that the interaction between inspiration source and event type had an overall effect on participants’ life satisfaction and future participation intention. Specifically, findings highlighted the different roles of inspiration on influencing life satisfaction and participation intention of short-distance (i.e. 5 and 10k) event participants than those of long-distance (i.e. marathon) runners.

Research limitations/implications
This study identifies the sources of inspiration in small-scale sport events and provides preliminary empirical evidence where inspiration source and event type jointly influence participants’ life satisfaction and behavioral intentions.

Practical implications
Understanding the sources of inspiration provides event leveraging opportunities to inspire citizens to become more active in sports. Given that the sources of inspiration vary among different segments of event participants, event managers need to adopt differential communication and promotional activities geared to the needs of these targets.

Originality/value
The study provides the first empirical work exploring the sources of inspiration among active participants in small-scale sport events.
The idea of transport independence in the Russian Arctic
Authors: Tsvetkova Antonina , Gammelgaard Britta 
Published: August 2018

Purpose
The purpose of this paper is to explore how supply chain strategies emerge and evolve in response to contextual influence.

Design/methodology/approach
A qualitative single-case study presents the journey of a supply chain strategy, conceptualised as the idea of transport independence in the Russian Arctic context. Data from 18 semi-structured interviews, personal observations and archival materials are interpreted through the institutional concepts of translation and editing effects.

Findings
The study reveals how supply chain strategies evolve over time and can affect institutional factors. The case study further reveals how contextual conditions make a company reconsider its core competencies as well as the role of supply chain management practices. The findings show that strategy implementation through purposeful actions can represent a powerful resistance to contextual pressures and constraints, as well as being a facilitator of change in actual supply chains and their context. During the translation of the idea of transport independence into actions, the supply chain strategy transformed itself into a form of strategic collaboration and thereby made supply chains in the Russian Arctic more integrated than before.

Research limitations/implications
More empirical studies on strategy implementation in interaction with contextual and institutional factors are suggested. An institutional process perspective is applied in this study but the authors suggest that future research should include a human dimension by an exploration of day-to-day routines and challenges that employees face when strategising and the actions they take.

Originality/value
The study provides an understanding of how a new supply chain strategy emerges and how it changes during implementation. In this process-oriented study – merging context, process and strategy content – it is further shown that a supply chain strategy may affect the context by responding to contextual and institutional challenges.
Student-led action for sustainability in higher education: a literature review
Authors: Murray Jaylene 
Published: August 2018

Purpose
Over the past few decades, universities have been recognized as ideal leaders for the development of policies and innovative solutions required to support the transition to sustainable societies. As a major stakeholder group, students play a significant role in moving this agenda forward; however, their actions remain understudied in the sustainability in higher education (SHE) literature.

Design/methodology/approach
In response, this systematic literature review was conducted to determine what research has been done on student-led action for SHE.

Findings
Findings demonstrate that while students are an understudied stakeholder group, there is a growing focus in the SHE literature on their contributions. The results suggest that students are working to increase the uptake of SHE through multi-stakeholder collaborations, collective action and interdisciplinarity. This review identifies a lack of engagement with intersectionality (interrelated environmental and social issues) and highlights the need to redirect future SHE research, calling for increased comparative research studies and research syntheses to provide greater depth to our understanding of student-led initiatives.

Research limitations/implications
This literature review is limited by the smaller sample size of articles; however, conclusions can nonetheless be drawn from these results to guide future scholarship. Implications exist for theoretical contributions to social movement theories and theories of organizational change for SHE.

Originality/value
This research provides insight into student-led action for SHE and how their efforts might better be supported to encourage the increased integration of SHE.
