Purpose Task recommendation is an important way for workers and requesters to get better outcomes in shorter time in crowdsourcing. This paper aims to propose an approach based on 2-tuple fuzzy linguistic method to recommend tasks to the workers who would be capable of completing and accept them. Design/methodology/approach In this paper, worker’s capability-to-complete (CTC) and possibility-to-accept (PTA) for a task needs to be recommended are proposed, measured and aggregated to determine worker’s priority for task recommendation. Therein, the similarity between the recommended task and its similar tasks and worker’s performance on these similar tasks are computed and aggregated to determine worker’s CTC quantitatively. In addition, two factors of worker’s active degree and worker’s preferences to a task category are presented to reflect and determine worker’s PTA. In the process of measuring them, 2-tuple fuzzy linguistic method is used to represent, process and aggregate vague and imprecise information. Findings To demonstrate the implementation process and performance of the proposed approach, an illustrative example is conducted on Taskcn, a widely used Chinese online crowdsourcing market. The experimental results show that the proposed approach outperformed the self-selection approach, especially for complex or creative tasks. Moreover, comparing with task recommendation considering worker’s CTC solely, the proposed approach would be better in terms of workers’ response rate. Additionally, the use of linguistic terms and fuzzy linguistic method facilitates the expression of vague and subjective information and makes recommendation process more practical. Research limitations/implications In the study, the authors capture alternative workers, collect workers’ behaviors and compute workers’ CTC and PTA manually. However, as the number of tasks and alternative workers grow, the issue, i.e. how to conveniently collect workers’ behaviors and determine their CTC and PTA, becomes conspicuous and needs to be studied further. Practical implications The proposed approach provides an alternative way to perform tasks posted in crowdsourcing platforms. It can assist workers to contribute to right tasks, and requesters to get outcomes with high quality more efficiently. Originality/value This study proposes an approach to task recommendation in crowdsourcing that integrates workers’ CTC and PTA for the recommended tasks and can deal with vague and imprecise information.

PurposeThis paper aims to investigate the role of a particular energy calculator in enhancing the energy efficiency of existing homes by asking how this calculator was developed and how it is domesticated by craftspeople working as energy consultants.Design/methodology/approachThe study is based on qualitative interviews with users and producers of the energy calculator (n= 22), as well as participation in energy consultation training.FindingsThe paper finds that, in the energy calculator, there is a striking lack of connection between the domestication and script because of lack of energy consultants’ involvement in the design and implementation process.Practical implicationsThe enrolment of energy consultants as energy calculator users earlier in and throughout the design process could be valuable in making the transition to an energy-efficient and environmentally friendly building sector.Social implicationsThe paper argues for recognition of the role of energy consultants, especially craftspeople, as participants in the design process for tools of governance. This is a call to acknowledge the value of particular skills and experiences possessed by craftspeople doing home consultation.Originality/valueBy understanding the intricate developer–user synchronicity in tools developed for upgrading the building sector, energy mitigation can be made more effective.

Purpose This study aims to identify the structural relationships among the drivers of lovemarks (mystery, sensuality, intimacy, trust, reputation and performance), lovemarks (brand love and brand respect) and loyalty of a name-brand coffee shop. Design/methodology/approach To this end, a self-administered questionnaire survey was conducted, and after eliminating the outliers, a total of 401 data were analyzed using the SPSS and AMOS statistical packages. Findings The results of the current study indicate that both customers’ brand love and respect are positively related to their brand loyalty and sensuality, intimacy, trust among drivers of lovemarks directly affecting their brand loyalty, suggesting that the theory of lovemarks is useful to understand the process of generating brand loyalty. Moreover, it was revealed that reputation and performance are significant antecedents of brand respect, while mystery, sensuality and intimacy are important to explain brand love. Practical implications The present research informed that effectively dealing with two constituents of lovemarks (brand love and brand respect) are of utmost importance in building patrons’ brand loyalty. In addition, patrons’ cognitive and emotional experiences should be improved to boost the level of loyalty for a name-brand coffee shop. Originality/value This study made a contribution to the literature by conceptually and empirically evaluating lovemarks’ dimensions simultaneously in the name-brand coffee shop environment. In addition, this research was the first attempt to explicate loyalty formation for a name-brand coffee shop by using the lovemarks theory.

Purpose – Much health service delivery occurs within a network structure, with co-operation and competition coexisting. Leading change for successful outcomes is a difficult task even outside of this multi-layered complex context, with reports that up to two-thirds of change processes are unsuccessfully implemented. This can have a major impact on stress, effectiveness and efficiency. This paper aims to address these issues. Design/methodology/approach – Theories supporting a generic implementation system for managers were explored so that people placed into situations in which they needed to lead and manage change could access a systematic approach that enabled clarification of the network's goal(s), valid communication among members of the network, and performance measurement using indicators the network agrees are meaningful. Findings – The implementation pathway developed provides a change process leaders and managers of change can use within networks. Practical implications – Health service funders and managers will be helped by this systematic implementation process. Originality/value – Health service funders and managers will be assisted by the systematic implementation process.

Purpose – The purpose of this paper is to analyze the status of the implementation of ISO 22000 in the food industry in Spain. The study identifies the main difficulties faced by firms during the adoption process, the benefits obtained, and the most influential benefits on firms overall satisfaction with ISO 22000. Design/methodology/approach – A questionnaire was developed to identify the difficulties and benefits for ISO 22000 implementation. Data were collected among 189 Spanish certified firms. Factor analysis and multiple linear regression were used. Findings – ISO 22000 is used by firms operating in all links of the food chain (FC). Size of the firm is not a factor that determines its implementation. Exporter firms are more attracted to ISO 22000 certification. All sample firms experienced difficulties throughout the implementation process, being those related with time and money the most relevant. The benefits which most contributed to the firms’ satisfaction were internal in nature, in particular, those related to improved efficiency and food safety. Practical implications – Despite the many difficulties, both material and organizational, that sample firms experienced in implementing ISO 22000, and the complexity of the standard, the overall satisfaction is high. Originality/value – The sample analyzed comprised certified firms, including representatives of all links in the FC from farm to table. Prior research specifically aimed at analyzing ISO 22000 implementation and its benefits is very scarce.

Purpose The purpose of this paper is to focus on the role of interviewee anxiety as a predictor of perceived hireability (Study 1, n=82) and job suitability (Study 2, n=74). Design/methodology/approach Using an experimental design, participants were randomly allocated to one of two conditions (an audio recording of either a confident or anxious job candidate with identical scripts) and asked to take the role of an interviewer. Findings The anxious interviewee (played by an actor) was consistently rated as less hireable (in a combined sample based on Studies and 2), less suitable to the job and received less favorable hiring recommendations (as assessed in Study 2) than the confident interviewee (played by the same actor). Research limitations/implications The study was conducted with students who may have less interview experience than experienced interviewers. Practical implications The results suggest that anxiety has a negative biasing effect on perceived hireability and job suitability ratings. In other words, the behavioral manipulation of anxiety affects hireability ratings, independent of any subjective assessment of anxiety. Originality/value The findings provide evidence of an anxiety bias in telephone interview settings. The results highlight the importance of considering anxiety cues when training employment interviewers.

Purpose The purpose of this paper is to develop and validate a Work Environment Complexity (WEC) Scale for leaders. Design/methodology/approach The paper uses both cross-sectional and longitudinal data, gathered in the course of major organisational restructuring, using samples from employees (n=305) and leaders (n=120) in two health care organisations. Findings The research developed and validated a scale of WEC for leaders with two factors: frequent change and events, and uncertain work demands. Comparisons between samples suggest diverging employee and leadership representations of WEC. Practical implications Being the first scale to measure the comprehensive construct of WEC, a foundation is laid to measure the amount of complexity in a leader’s work and the functioning of leaders with regards to WEC. Originality/value This paper contributes to leadership research and practice by clarifying the construct of WEC for leaders empirically and validating a bidimensional scale of WEC.

Purpose The purpose of this paper is to analyze the innovation strategies of the sugar–energy industry in Central-Southern Brazil with regard to its resource structure and results. Design/methodology/approach The data were collected through a questionnaire covering the three-year period from 2015 through 2017. The results were extracted based on a combination of factor analysis and multiple regression analysis. Findings The innovation strategies of Brazilian sugar–energy companies are characterized as defensive and imitative based on the resources dedicated to innovation and the implementation of innovation with respect to products, processes, eco-innovation and cost reductions. Research limitations/implications The sample is representative, but it does not cover all companies in the Brazilian sugar–energy industry. The data were acquired using a survey, and the results could not be compared to the financial results of the companies. Practical implications Sugar–energy companies need to define their innovation strategies, as these strategies lead to different results that can be achieved only through the management of resources dedicated to the generation and implementation of innovations. Managers and analysts need to know the profile of these innovation strategies to evaluate the effectiveness of the results based on the resources that were invested. Originality/value This study presents an exploratory model that identified two factors related to innovation efforts and three results. It is possible to define the innovation strategies of companies in the Brazilian sugar–energy industry, which is one of the most competitive in Brazil.
