Research on the collaboration–innovation nexus emphasises that collaborations and innovation are multidimensional. Despite this emphasis, there is limited evidence on how firms' collaborative diversity affects their innovation diversity. This paper addresses this gap by examining the relationships between (i) a firm's functional diversity of collaboration (FDC) and innovation diversity, and (ii) innovation diversity and firm growth. We used longitudinal data from 738 Australian food firms, and our findings suggest that the positive relationship between FDC and innovation diversity reaches a point of saturation, beyond which additional collaboration negatively influences firms' innovation diversity. Moreover, innovation diversity depends on the motives behind alliance formation and the firm's focus on innovation. Finally, the association between innovation diversity and growth performance is heterogeneous across firms' conditional growth rate distribution.

In discussions about the goals we should set for our policies and programs, there are some familiar moral reasons to think that hope and resilience should often be included. In particular, hope and resilience are both widely recognized as moral virtues, and they may be vital for social cohesion. To demonstrate the feasibility of modelling and measuring the relevant variables and of putting them to use, we developed and tested a number of hypotheses. Drawing upon survey data that we collected from 429 participants (211 Indigenous Australians and 218 non-Indigenous Australians'), we found that favourable beliefs about the quality of government support are positively associated with greater levels of hope and resilience. Hope and resilience, in turn, are positively associated with greater satisfaction with life. But most interestingly, we found a strong and widespread positive association between fully recognizing the legacy of historical injustices in Australia and having hope.

Food waste significantly contributes to complex socioeconomic and environmental problems. The tourism sector is not immune to these sustainability challenges. This research examines how both negative and positive emotions build tourists’ intentions to reduce food waste. The study employs two experiments and a survey to establish causality among the key constructs and test the nomological network of those constructs. Results demonstrate a causal relationship between guilt, regret and hope and how these constructs interplay to explain the impact of a tourist’s perceptions of potential cost and harm from not implementing food waste-reduction practices. Additionally, four tourist categories are developed using fuzzy-set Qualitative Comparative Analysis (fsQCA). The results of fsQCA identify different configurations of tourists who seek to reduce food waste. This study encourages tourism operators to leverage positive emotions, such as hope, in marketing communications to encourage food waste reduction. A key contribution of this work is the examination of the variable of ‘hope’, and its effect in the context of food waste behaviour among tourists. This is the first study to examine how the interaction between tourists’ negative (guilt and regret) and positive (hope) emotions motivates their intentions to reduce food waste.

Purpose- The purpose of this paper is to investigate the relationship between ethical leadership and academics' retention in universities. It draws on the conservation of resources theory to deepen the understanding of a process underlying this relationship whereby academics are more likely to stay in universities through the practice of ethical leadership. Specifically, it advances academics' job-related affective well-being as a potential mediating mechanism, fostered by ethical leadership, which lowers their intention to leave.

Design/methodology/approach - This study is conducted through a cross-sectional survey of 303 academics in Australian universities. Univariate, bivariate and multivariate analysis procedures are deployed to analyse academics' data. The research hypotheses are tested through a bootstrapped regression analysis of academics' perceived ethical leadership, affective well-being and intention to leave.

Findings - The findings lend support to the hypothesised relations, indicating a significant role of ethical leadership on enhanced intentions of academics to stay in universities by directly conserving their job-related affective well-being.

Research limitations/implications - This paper contributes to knowledge of the relationship between ethical leadership and academics' retention by identifying job-related affective well-being as an underlying mechanism in the university sector.

Practical implications -

This paper has practical implications for higher educational institutes seeking to retain their academic staff. Its findings show that the practice of ethical leadership in universities matters, because it lowers academics' intentions to leave by nurturing their well-being at work.

Originality/value - This is the first study to examine the impact of ethical leadership on academics' well-being and intentions to leave in the context of universities in Australia. It is one of the first studies to explore the mediating role of affective well-being in the ethical leadership and leadership and intention to leave relationship.
