Using Twitter to explore consumers' sentiments and their social representations towards new food trends
Authors: Pindado Emilio , Barrena Ramo 
Published: November 2020

PurposeThis paper investigates the use of Twitter for studying the social representations of different regions across the world towards new food trends.Design/methodology/approachA density-based clustering algorithm was applied to 7,014 tweets to identify regions of consumers sharing content about food trends. The attitude of their social representations was addressed with the sentiment analysis, and grid maps were used to explore subregional differences.FindingsTwitter users have a weak, positive attitude towards food trends, and significant differences were found across regions identified, which suggests that factors at the regional level such as cultural context determine users' attitude towards food innovations. The subregional analysis showed differences at the local level, which reinforces the evidence that context matters in consumers' attitude expressed in social media.Research limitations/implicationsThe social media content is sensitive to spatio-temporal events. Therefore, research should take into account content, location and contextual information to understand consumers' perceptions. The methodology proposed here serves to identify consumers' regions and to characterize their attitude towards specific topics. It considers not only administrative but also cognitive boundaries in order to analyse subsequent contextual influences on consumers' social representations.Practical implicationsThe approach presented allows marketers to identify regions of interest and localize consumers' attitudes towards their products using social media data, providing real-time information to contrast with their strategies in different areas and adapt them to consumers' feelings.Originality/valueThis study presents a research methodology to analyse food consumers' understanding and perceptions using not only content but also geographical information of social media data, which provides a means to extract more information than the content analysis applied in the literature.
The emergence of biological invasions on food chains: a DPSIR analysis
Authors: Faraudello Alessandra , Gualtieri Donato , Szeles Zsuzsanna 
Published: November 2020

PurposeThe purpose of this paper is to illustrate the emergence of a biological invasion and to explain the potential economic and social consequences on food chains. Straddling between ecology, social sciences, resource management and economics, invasion science is aimed at detecting, understanding and mitigating the impact of biological invasions on receiving ecosystems, including food ecosystems.Design/methodology/approachAfter a theoretical investigation about the main notions relevant for the invasion science, the authors practically review the kind of impacts deriving from biological invasions, mainly under economic, human health, ecosystem and biodiversity criteria.FindingsThe authors apply the DPSIR (Driving forces–pressure-state-impact-response) framework, originally developed in the context of European Environment Agency in this different context in order to assess the social, economic and environmental impacts of Invasive Alien Species (IAS). Responding to this emerging phenomenon, the European Union issues the EU regulation 1143/2014 which is the first strong act on invasive alien species.Originality/valueImplications – Food chains are complex systems that have multiple interdependencies both endogenously and exogenously, such as food production, food transportation, food logistics, food distribution, and so forth. However, it is rarely conceived the impact of invasion systems on the dynamics of food chains, although food sustainability is in turn impacted by how effectively and efficiently the various interdependencies have been designed or are working.

Authors: Qiyas Muhammad , Khan Muhammad Ali , Khan Saifullah , Abdullah Saleem 
Published: November 2020

PurposeThe aim of this study as to find out an approach for emergency program selection.Design/methodology/approachThe authors have generated six aggregation operators (AOs), namely picture fuzzy Yager weighted average (PFYWA), picture fuzzy Yager ordered weighted average, picture fuzzy Yager hybrid weighted average, picture fuzzy Yager weighted geometric (PFYWG), picture fuzzy Yager ordered weighted geometric and picture fuzzy Yager hybrid weighted geometric aggregations operators.FindingsFirst of all, the authors defined the score and accuracy function for picture fuzzy set (FS), and some fundamental operational laws for picture FS using the Yager aggregation operation. After that, using the developed operational laws, developed some AOs, namely PFYWA, picture fuzzy Yager ordered weighted average, picture fuzzy Yager hybrid weighted average, PFYWG, picture fuzzy Yager ordered weighted geometric and picture fuzzy Yager hybrid weighted geometric aggregations operators, have been proposed along with their desirable properties. A decision-making (DM) approach based on these operators has also been presented. An illustrative example has been given for demonstrating the approach. Finally, discussed the comparison of the proposed method with the other existing methods and write the conclusion of the article.Originality/valueTo find the best alternative for emergency program selection.
Inbound Australian tourism demand from Asia: a panel gravity model
Authors: Ghosh Sudeshna 
Published: November 2020

PurposeThis study attempts to explore the determinants of tourism demand that impact tourist arrivals in Australia from Asia using an augmented panel gravity model.Design/methodology/approachThe augmented panel gravity model was utilised to analyse the demand for Australian tourism from 15 major countries of Asia over the period 1991 to 2018. Tourist arrivals were the dependent variable while per capita gross domestic product (GDP) and weighted distance were important explanatory variables. Further other indicators like population, money supply, globalisation, price index, exchange rate, uncertainty and two dummy variables were added as control variables.FindingsThe results demonstrate based on the novel methodology of Pesaran (2006), namely CCE (common correlated effects) that tourist arrivals are impacted positively and significantly by per capita GDP of both the country of origin and destination country, globalisation also impacts tourist flows positively. However, tourist arrivals are adversely affected by distance and prices confirming the economic theory.Originality/valueGravity models have been intensively used in the recent literature on tourism; however, this study has attempted to explore tourism demand from Asia into Australia which is indeed an unexplored area further the study has used the CCE methodology which takes care of the problems of cross-sectional dependence unlike the earlier methods widely used in the literature like the DOLS and the FMOLS. Last by utilising a wide-ranging set of macro factors the study contributes a novel assessment to the recent literature on tourism demand model.
Transboundary air pollution and respiratory disease mortality: evidence from European countries
Authors: Spiteri Jonathan , von Brockdorff Philip 
Published: November 2020

PurposeThe aim of this paper is to quantify the impact of transboundary air pollutants, particularly those related to urban traffic, on health outcomes. The importance of focusing on the health implications of transboundary pollution is due to the fact that these emissions originate from another jurisdiction, thus constituting international negative externalities. Thus, by isolating and quantifying the impact of these transboundary air pollutants on domestic health outcomes, the authors can understand more clearly the extent of these externalities, identify their ramifications for health and emphasise the importance of cross-country cooperation in the fight against air pollution.Design/methodology/approachThe authors employ panel data regression analysis to look at the relationship between emissions of transboundary air pollution and mortality rates from various respiratory diseases among a sample of 40 European countries, over the period 2003–2014. In turn, the authors use annual data on transboundary emissions of sulphur oxides (SOx), nitrogen oxides (NOx) and fine particulate matter (PM2.5), together with detailed data on the per capita incidence of various respiratory diseases, including lung cancer, asthma and chronic obstructive pulmonary disease (COPD). The authors consider a number of different regression equation specifications and control for potential confounders like the quality of healthcare and economic prosperity within each country.FindingsThe results show that transboundary emissions of PM2.5 are positively and significantly related to mortality rates from asthma in our sample of countries. Quantitatively, a 10% increase in PM2.5 transboundary emissions per capita from neighbouring countries is associated with a 1.4% increase in the asthma mortality rate within the recipient country or roughly 200 deaths by asthma per year across our sample.Originality/valueThese findings have important policy implications for cross-country cooperation and regulation in the field of pollution abatement and control, particularly since all the countries under consideration form a part of the UN's Convention on Long-Range Transboundary Air Pollution (CLRTAP), a transnational cooperative agreement aimed at curtailing such pollutants on an international level.
Conceptualizing social well-being in activity-based offices
Authors: Colenberg Susanne , Appel-Meulenbroek Rianne , Romero Herrera Natalia , Keyson David 
Published: November 2020

PurposeThe purpose of this article is to aid conceptualization of social well-being at work by identifying its components in a contemporary office context, so adequate measures can be developed to monitor social well-being and to assess the impact of interventions in the workplace.Design/methodology/approachThis study used existing interview data from recent post-occupancy evaluations of two large activity-based flexible offices in the Dutch public sector. Data-driven concept mapping of 182 different employees' statements on social aspects of well-being was used to find communalities in their perceptions.FindingsFrom the data 14 key concepts emerged referring to employees' social needs, reactions to (anti-)social behaviour of others and perceived social affordances of the work environment. Contrary to established theory, social well-being appeared to be a context-bound phenomenon, including components of both short-term hedonic and long-term eudaimonic well-being.Research limitations/implicationsThe findings serve as an inductive source for the further development of adequate measures of social well-being at work. Limitations concern the specific (cultural) setting of the cases and the use of existing data.Practical implicationsPreliminary suggestions for fostering social well-being include change management, participatory design, being alert of the identified risks of activity-based offices and supporting privacy regulation, identity marking and a sense of community, as well as a diversity of informal face-to-face interactions balanced with quiet spaces.Originality/valueThis article contributes to the conceptualization of social well-being in contemporary offices by discussing established social well-being theory and analysing real-world data, using a method novel to management research.
Effects of modular platforms on suppliers companies: evidence from Volkswagen Polo manufacturing in Navarra (Spain)
Authors: Paz María J. , Ruiz Gálvez María E. 
Published: November 2020

PurposeThis paper analyzes the effects on local suppliers of the adoption of a modular platform, taking into account different supply-chain relations.Design/methodology/approachThe authors’ research follows an interpretive case study methodology based on a theoretical approach that seeks to validate the approach while making conclusions about the case study.FindingsThe traditional pyramidal structure of automotive supply chains has been altered by the consolidation of a much more complex structure, mostly in spatial and geographical terms. The authors find a strong hierarchy resulting from the reinforced market power of the carmaker under study and the respective fragile structural positioning of logistics companies and pre-assemblers. The increased versatility of the assembly plant, considered a consequence of its transition to modular platforms, finds a counterpart in the necessary re-configuration of certain supply relationships.Originality/valueThe main contribution of the paper is to connect the defining elements of supply-chain relations with those technical and organizational changes associated with the transition to modular platforms, as well as to analyze changes in the pyramidal structure of the supply chain, from both a spatial and relational perspective.
Green supply chain management practices and its impact on organizational performance: evidence from Indian manufacturers
Authors: Sahoo Saumyaranjan , Vijayvargy Lokesh 
Published: November 2020

PurposeThe purpose of this paper is to explore the impact of five dimensions of green supply chain management (GSCM) practices (i.e. internal environmental management, green purchasing, cooperation with customers, eco-design, and investment recovery) on three dimensions of organizational performance (i.e. environmental, economic and operational performance).Design/methodology/approachData were collected based on a cross-sectional survey of managers of 160 manufacturing firms in India. Structural equation modelling was used to test the influence of GSCM practices on each of the organizational performance outcomes.FindingsExcept for internal environmental management and green purchasing, all other GSCM dimensions are found to significantly impact at least one of the performance dimensions, either directly or indirectly. The results highlight that investment recovery practice is a key predictor of environmental performance, whereas eco-design is a key predictor of operational performance. The structural equation modeling result also suggests that GSCM do not directly affect economic performance, but can improve it indirectly.Research limitations/implicationsSince data was collected from managers of manufacturing firms on the basis of their subjective evaluations, future research studies should employ objective performance indicators for analysis. Also, the study did not consider some dimensions of GSCM practices, which can be included in future studies.Practical implicationsManufacturing firms should implement GSCM practices not just because of the pressure from regulatory bodies but also to elevate their environmental, operational and economic performance. The proposed model in this paper suggests practitioners which GSCM factors are driving these performance changes and supports the building of a roadmap for GSCM implementation in their organization.Originality/valueManufacturing firms from four different operating sectors, namely automotive, electrical and electronics, process and machinery sectors are the respondents. The originality of the paper lies in testing the influence of GSCM practices on organizational performance in a novel context, where most GSCM initiatives fail for one reason or another. Furthermore, the assessment of the interaction between five constructs of GSCM practices and three constructs of organizational performance in the Indian manufacturing context offers unique conceptual contribution to the researches in the GSCM field.
Corporate social responsibility during unprecedented crises: the role of authentic leadership and business model flexibility
Authors: Fox Corey , Davis Phillip , Baucus Melissa 
Published: November 2020

PurposeThe purpose of the present research is to explore the relationships between corporate social responsibility (CSR), authentic leadership and business model flexibility during times of unprecedented crises.Design/methodology/approachThe research approach in this study is conceptual. After a brief review of the literature associated with CSR, authentic leadership and business models, the authors introduce a model describing the interaction of authentic leadership and business model flexibility on CSR heterogeneity.FindingsThis research explains how firms that are led by authentic leaders and that have flexible business models will be more engaged with their stakeholders than firms with less authentic leaders or more rigid business models during unprecedented crises.Practical implicationsPrescriptions for practitioners are suggested for improving authentic leadership as well as making adaptations to the firm's business model. Regarding authentic leadership, firms can screen potential new hires and existing employees for authentic leadership qualities. Firms can also rely upon existing interventions shown to assist in authentic leadership development for current leaders. At the business model level, firms can focus on core resources and their application in related product and service markets.Originality/valueFirms engaged in CSR activities benefit more from those activities when leaders are authentic. However, in times of unprecedented crises, business model flexibility may also dictate the extent to which firms can satisfy their stakeholders. The authors introduce a conceptual model that takes the elements of authentic leadership and business model flexibility into account to explain CSR heterogeneity.
Corporate sustainability: the new organizational reality
Authors: Dhanda Upasana , Shrotryia Vijay Kumar 
Published: November 2020

PurposeToday, corporate sustainability is at a tipping point. With average lifespan of organizations shrinking, striving for corporate longevity and sustainability has become indispensable in this fast-paced world. Despite the growing interest in this domain, companies are struggling to define sustainability in a way that is relevant to their business. This article attempts to synthesize the extant literature and provide a conceptual perspective on corporate sustainability and sustainable business models.Design/methodology/approachThematic literature review was done to gain an understanding of the extant literature and the ongoing debates on organizational sustainability. As the literature in context of corporate sustainability was found to be in a fluid state, a thematic review was found suitable to systematize and disclose valuable insights that open avenues for addressing sustainability concerns.FindingsThe paper attempts to throw light on the journey of organizations towards sustainability and how the context of sustainability has changed for the organizations over time. The paper discusses how companies embarked on their sustainability revolution by shifting their focus from mere compliance and philanthropy to attaining a sustainability edge and also explicates the transformation from traditional business models to sustainable business models. Finally, the research gaps are identified to pave the way for future research in the domain of corporate sustainability.Originality/valueThe extant literature on corporate sustainability is in a shambolic state. This creates a need to investigate what has been done and how the context of corporate sustainability is being shaped. This paper contributes to the emerging literature on sustainability by providing a conceptual perspective and highlighting the research gaps which pave the way for future research on sustainability paradigm.
Reproductive senescence in a short‐lived fish
Authors: Žák Jakub , Reichard Martin 
Published: November 2020

Abstract

Reproductive senescence is an age‐associated decline in reproductive performance, which often arises as a trade‐off between current and future reproduction. Given that mortality is inevitable, increased allocation into current reproduction is favoured despite costs paid later in life.

This assumption is violated in organisms with post‐maturity growth whose reproductive output increases long after maturity. While reproductive senescence is frequently studied in animals with determinate growth at maturity, such as insects or mammals, we have very limited understanding of reproductive senescence in organisms with an extensive post‐maturity growth period.

The fact that many post‐maturity growers experience strong adult mortality leads to conflicting expectations for reproductive senescence. The aim of this study was to investigate how co‐occurrence of rapid life history and post‐maturity growth mould reproductive senescence in a short‐lived killifish, Nothobranchius furzeri, using longitudinal data on laboratory and wild‐type populations.

We followed the individual fecundity, fertility and fertilization of 132 singly housed fish from the perspectives of chronological and biological age. At the onset of senescence, the sex‐specific contribution to decrease in fertilization capacity was investigated. Allocation trade‐offs were estimated through the association between reproductive parameters and life span, and between early‐life and late‐life fecundity.

We demonstrate that female fecundity increased steadily after maturity and reproductive senescence occurred long after the growth asymptote. The prime age for fecundity coincided with 50% female survival and consequent decline in fecundity implies an association with somatic deterioration. Reproductive senescence in fertilization rate was stronger in females than in males. Females with high early fecundity experienced a long life span and high late‐life fecundity, discounting the role of allocation trade‐offs in reproductive senescence.

The present study reports a clear case of reproductive senescence in a fish with a long post‐maturation growth period, unusually rapid development and short life span. The onset of reproductive senescence was postponed compared to animals that cease growing at sexual maturity. Fish and other animals with post‐maturity growth have long been considered insusceptible to ageing but this conclusion may be related to the previous lack of longitudinal data rather than to the absence of reproductive senescence in such organisms.
