Abstract
Purpose
Visual Distinctive Language (VDL)-based iconic tags are structured visual information annotation. They explicate the content and organization of tagged information by graphical and symbolic features in order to improve the vocabulary problems of textual tags. The purpose of this paper is to investigate how these special icons help in tagged-based user information searching.
Design/methodology/approach
A two-stage experiment was designed and conducted so as to follow and quantify the searching process in specific searching target case and no specific searching target case when using VDL-based iconic tags.
Findings
The experimental results manifested that VDL-based iconic tags enhanced the role of tag in information searching. They could make user better understand tag clusters, which, in turn, provide global structure of involved topics. Also, VDL-based iconic tags helped user to find out searching target more quickly with higher accuracy by taking advantages of visual representation of tag categories and symbolic signification of tag content.
Originality/value
This study is one of the first to verify how structured icons work in information searching and how user’s graphical cognition impacts on tag-based information searching process. The research findings are dedicated to the theory of VDL-based iconic tags, as well as to a new visualization method for search user interface design.

Abstract
Purpose
Most of the existing studies on the evolution of emergency topics in social media focused on the emergency information demand of fixed user type in emergency while ignoring the changing roles of stakeholders during the emergency. Thus in this study, a three-dimensional dynamic topic evolution model is proposed, in which fine grained division of time, dynamic identification of stakeholders in the emergency, and emergency topic evolution based on both timeline and stakeholder's type are all considered.
Design/methodology/approach
Particularly the relevance between the tweets posted and the topic of emergency, the influence on the social network, and the attention of emergency topic are as well taken into account to quantitatively calculate the weight and ranking of stakeholders at different stages of the emergency. To verify the proposed model, an experimental demonstration was carried out under an emergency event posted on social media.
Findings
The results show that (1) based on the three-dimensional dynamic topic evolution model, the composition and ranking of stakeholders have obvious differences at different stages; (2) the emergency information needs and the sharing behavior of stakeholders on emergency information also indicate different preferences where the topic concerns of stakeholders at different stages have a strong relationship with their weight ranking; (3) the emergency topic evolution considering both the dynamics of emergency stakeholders and emergency information demand could more accurately reflect the changing regularity of social media users' attention to information in emergency events.
Originality/value
This study is one of first to investigate the emergency topic evaluation on social media by considering the dynamic changes of various stakeholders in emergency. It could not only theoretically provide more accurate method to understand how users share and search emergency information in social media, but also practically signify an information recommendation way in social media for emergency tracking.

Abstract
Milton Nascimento is one of the most prolific Brazilian singers and songwriters of all time, an artist who has formed friendships and made songs with a host of Brazilian artists, with international stars from Latin America, and with artists abroad. Milton’s repertoire has made its way into the fabric of musical compilations of Brazilian music for international listeners. Perhaps unbeknownst to these international listeners, Milton, as an Afro-Brazilian artist, reflects a complex and paradoxical relationship to “race” in his music – at times openly touching upon racial themes, even during an area when the government forbade open discussion of racial tension in Brazil – but at times signifying race more subtly, either through subtle references to diversity in Brazil or through the very elements of his music.

Abstract
Purpose
This study examines the direct and indirect effects of organizational environmental orientation (EO)/culture, quality management practices (QMP) and sustainability experience (SE) on the relationship between organizational green practices (GP) and the triple bottom line (TBL) of sustainability performance (SuP).
Design/methodology/approach
To test the seven hypotheses, a structured questionnaire was used to collect data. The responses of 365 managers from various USA businesses in the service industries were analyzed using IBM SPSS and structural equation modeling (SEM)-AMOS.
Findings
The empirical results indicate that positive SuP in the economic, environmental and social dimensions and organizational GP can be improved by a strong culture of EO, effective QMP and substantial SE.
Practical implications
This research fills the gap in existing research between important organizational and environmental priorities and SuP. Consequently, the study provides managers with important strategic guidance: for environmental practices to achieve profitability and sustainability success, companies must promote an environmental-mindful culture and strategically invest in integrated QM systems.
Originality/value
This research is one of the first that explores how organizational environmental culture and QMP affect directly and indirectly the relationship between GP and SuP. These results provide empirical evidence to support the claim that environmental culture and QMP have significant direct and indirect effects on the relationship between GP and SuP dimensions.

Abstract
Purpose
The purpose of this paper is to provide new ways of thinking about what motivates consumers to choose the green alternative, ideas that will be helpful in reducing the unsatisfactory green attitude-behaviour gap. Consumers have many self-aspects. This paper shows why it is necessary to activate consumers’ pragmatic selves if we want to predict purchase behaviour. The pragmatic self is concerned with costs and reference prices. When researchers activate consumers’ idealistic selves, they get idealistic answers which deviate from actual behaviour. The study also distinguishes between green alternatives with desirable green or non-green self-benefits, and green alternatives with other-benefits that are difficult to comprehend.
Design/methodology/approach
This study is based on a consumer survey and the data is analysed with structural equation modelling. The concept environmental colour is introduced to understand purchase differences between different consumer segments on the market.
Findings
This study shows that consumers buy benefits, which is why dark brown consumers choose the green alternative when it has a competitive advantage. It also shows that the propensity to choose the green alternative is highest among consumers who in addition see green as a benefit and have the habit of buying other green products. Another result is that the green consumers have higher self-awareness than brown consumers and are very cost conscious.
Practical implications
Good decisions are based on what consumers actually do, not what they say they would like to do. This paper offers practical help on understanding consumers’ purchase criteria and how to activate their pragmatic selves. Much more could be done to promote the pro-self and pro-social benefits of making sustainable choices.
Social implications
To get a sustainable world, it is urgent to understand what motivates consumers to pay extra for environmentally friendly alternatives.
Originality/value
This paper offers new theoretical insights on how researchers can reduce the green gap.

Abstract
Purpose
The purpose of this paper is to examine the relationship of masculine eating/drinking beliefs on male consumers’ concern with unhealthy eating/drinking habits and, in turn, with binge drinking. Additionally, this research tests if and how a change in these beliefs influences binge drinking intention and intention to eat unhealthy food.
Design/methodology/approach
Three studies were conducted in Bogotá (Colombian males; convenience sampling). The purpose of Study 1 (N = 209) was to develop a scale to measure masculine eating/drinking beliefs. Study 2 (N = 191) tested the mediating role of concern with unhealthy eating/drinking habits in the relationship of masculine eating/drinking beliefs with binge drinking. Study 3 (N = 179) was an experimental study, which examined the effect of information about some negative consequences of masculine beliefs on the answers to the masculine eating/drinking beliefs inventory and, in turn, on binge drinking intention and intention to eat unhealthy food.
Findings
A one-dimensional (eight-items) scale was developed and validated. The results of this paper show that masculine eating/drinking beliefs are associated with lower concern with unhealthy eating/drinking and, in turn, with higher binge drinking. Information that influences these beliefs leads to lower binge drinking and unhealthy food ingestion intentions.
Research limitations/implications
This research presents the first scale that measures masculine eating/drinking beliefs. It provides initial evidence on how an intervention focused on the negative consequences of sexism can influence these beliefs, affecting binge drinking and overeating intentions.
Practical implications
This research provides new findings on a topic associated with several health problems in many countries, including the effect on consumers’ weight gaining and related illnesses.
Originality/value
This research presents the first scale that measures masculine eating/drinking beliefs. It provides initial evidence about factors (through mediating variables) that link masculine eating/drinking beliefs with some unhealthy eating/drinking habits. In addition, the results show how information about some negative consequences of these beliefs can influence consumers’ binge drinking and unhealthy food ingestion intentions, which leads to key recommendations for future interventions. As a result, this research provides new findings on a topic associated with several health problems in many countries, including the effect on consumers’ weight gaining and related illnesses.
