Abstract
Purpose
Aversion linked to disgust and neophobia is the primary reason for human reluctance towards edible insects as a sustainable food source. Stimulating positive emotions may overcome these mental barriers. Cute visuals and claims on product packaging can trigger positive affective responses in consumers whilst modulating taste expectations. This study investigated how these elements influence emotions, perceptions and attitudes towards insect-based foods.
Design/methodology/approach
An online cross-cultural study involving French (n = 747) and Colombian (n = 695) consumers was conducted using two insect-based products: chips (hedonic) and bread (functional). Ten visual packaging variations were created per product, emphasising palatability, sustainability, nutrition and popularity (plus a control: no claim) affixed to the image of a cute anthropomorphic cricket or its silhouette. Visual appreciation and associations were assessed along with the participants' degree of food variety seeking, familiarity with entomophagy and openness to consuming edible insects.
Findings
Differences were reported in emotions, perceptions and attitudes based on the combination of packaging elements, product type and consumer segments. The findings suggest that food marketers should use cute insect depictions linked to palatability-focussed claims to alleviate young French adults' reluctance towards insect-based foods (IFs). Colombians responded better to pro-social claims and neutrally to cuteness.
Practical implications
The results should be valuable to stakeholders seeking to enhance food marketing strategies related to IFs amongst target consumer segments.
Originality/value
This study is the first to assess how baby schema cuteness induces emotional changes towards IFs and how it affects perceptions and attitudes amongst distinct populations and age segments.

Abstract
Purpose
Observation of the animal world is an important component of nature surveys. It provides a number of different information concerning aspects such as population sizes, migration directions, feeding sites and many other data. The paper below presents the results from the flights of an unmanned aerial vehicle (UAV) aimed at detecting animals in their natural environment.
Design/methodology/approach
The drone used in the research was equipped with RGB and thermal infrared (TIR) cameras. Both cameras, which were mounted on the UAV, were used to take pictures showing the concentration of animals (deer). The overview flights were carried out in the villages of Podlaskie Voivodeship: Szerokie Laki, Bialousy and Sloja. Research flights were made in Bialousy and Sloja. A concentration of deer was photographed during research flights in Sloja. A Durango unmanned platform, equipped with a thermal imaging camera and a Canon RGB camera, was used for research flights. The pictures taken during the flights were used to create orthomaps. A multicopter, equipped with a GoPro camera, was used for overview flights to film the flight locations. A flight control station was also used, consisting of a laptop with MissionPlanner software.
Findings
Analysis of the collected images has indicated that environmental, organisational and technical factors influence the quality of the information. Sophisticated observation precision is ensured by the use of high-resolution RGB and TIR cameras. A proper platform for the cameras is an UAV provided with advanced positioning systems, which makes it possible to create high-quality orthomaps of the area. When observing animals, the time of day (temperature contrast), year season (leaf ascent) or flight parameters is important.
Originality/value
The paper introduces the conclusions of the research flights, pointing out useful information for animal observation using UAVs.

Abstract
Purpose
This paper aims to extend the current knowledge about how food neophobia and food technology neophobia can influence whether consumers choose fish farmed with insect-based flours (FFIF).
Design/methodology/approach
The authors used an online survey questionnaire and a sample of 567 young Italian adults. The answers were analysed using fuzzy-set qualitative comparative analysis and structural equation modelling.
Findings
Both methodologies highlighted the relevance of food technology neophobia in influencing consumers' attitudes and intentions, even when foodstuffs were not produced through technology-intensive processes.
Research limitations/implications
Despite being focussed on a sample containing people of similar ages and food cultures, this study offers evidence that it is not necessarily the technological level of a food production process that sparks feelings of technology-related neophobia. Thus, this study highlights the importance of consumers' perceptions of foodstuff choices.
Practical implications
The findings provide valuable insights into how informative campaigns should address the problem of increasing the acceptance of novel foods, such as FFIF.
Originality/value
The present study provides empirical evidence that food technology neophobia can influence whether consumers choose FFIF. Furthermore, using a mixed-method approach is novel in the field of new foods.

Abstract
Purpose
Current evidence indicates that humans and animals are at increased risk of multiple health challenges due to microplastic (MP) profusion. However, mitigation is constrained by inadequate scientific data, further aggravated by the lack of evidence in many African countries. This review therefore synthesized evidence on the current extent of MP pollution in Africa and the analytical techniques for reporting.
Design/methodology/approach
A literature search was undertaken in research databases. Medical subject headings (MeSH) terms and keywords were used in the literature search. The authors found 38 studies from 10 countries that met the inclusion criteria.
Findings
Marine organisms had MPs prevalence ranging from 19% to 100%, whereas sediments and water samples had between 77 and 100%. The most common and dominant polymers included polypropylene and polyethylene.
Practical implications
This review shows that most studies still use methods that are prone to human errors. Therefore, the concentration of MPs is likely underestimated, even though the authors’ prevalence evaluations show MPs are still largely pervasive across multiple environmental matrices. Also, the study reveals significant spatial disparity in MP research across the African continent, showing the need for further research in other African countries.
Originality/value
Even though some reviews have assessed MPs pollution in Africa, they have not evaluated sample prevalence, which is necessary to understand not only concentration but pervasiveness across the continent. Secondly, this study delves deeper into various methods of sampling, extraction and analysis of MPs, as well as limitations and relevant recommendations.

Abstract
Purpose
The purpose of this study is to enhance the functional properties of Hessian fabric through resin finishing. Hessian bags made of lignocellulosic jute fiber are commonly used to pack, store and transport agro-commodities, including horticultural crops such as rice, potato, onion and wheat. However, because of high water affinity, these bags undergo degradation in properties due to moisture release by the stored commodities themselves. Exposure to natural elements, e.g. rain and dew, also causes moisture absorption in hessian bags. Once the bag gets moistened, degradation of jute bags starts due to microbial attack, leading to loss in tensile strength and change in extensibility, leading to ultimate breakage in warp and weft directions of the fabric.
Design/methodology/approach
To overcome the degradation in the functional properties of hessian fabric due to exposure to moisture and microbial attack, the application of semi-synthetic polymeric materials was carried out.
Findings
Tenacity, bursting strength, puncture resistance, tear strength and breaking load, as well as life cycle of resin-treated jute fabric was found to be better than control jute.
Originality/value
To the best of the authors’ knowledge, no recent reports of resin finishing on jute (hessian) fabric with semi-synthetic resins are presently available, other than coating with rubber.

Abstract
Purpose
Phonecards were largely used in African countries for telephone services. They have been collected by people around the world as a hobby. Images from several themes were printed in phonecards, including insects (beetles, butterflies, dragonflies, etc.). We hypothesized that the display of butterfly images in phonecards aimed to arise issues associated with butterfly endangerment and conservation status by protecting their natural habitat and/or butterfly beautifulness, and that they present “extinct” or “threatened” conservation status classification. The purpose of this study is to describe how butterfly images were used in African phonecards; to identify the butterfly species name through their images and information available in all African phonecards; and to record the most recent known geographical distribution and conservation status of butterflies.
Design/methodology/approach
Colnect database was assessed to identify all butterfly-themed African phonecards. International Union for Conservation of Nature database was also assessed to obtain information on the most recent known geographical distribution and conservation status of butterflies.
Findings
The species name of butterflies was identified from 6 out of 18 African phonecards. The most recent known geographical distribution of butterflies was wide across Africa and conservation status of most genera is classified as “least concern”.
Originality/value
The display of butterfly images in African phonecards is mostly associated with their beautifulness and least related with butterfly conservation, protection and endangerment status.

Abstract
Purpose
The use of insects as food is a proposed solution for the increased demand for food worldwide, but it lacks acceptance because of restrictive emotional factors. This article aims to understand better customers' emotions’ role in considering and consuming insect-based food.
Design/methodology/approach
To assess their acceptance, an experiment was developed with 38 participants living in Portugal to identify how people feel when consuming processed insect bars compared to cereal bars (of equal flavour). A video was recorded “before”, “during” and “after” the consumption of such foods, and the triggered emotions and affective states were identified using the Facial Action Coding System (FACS) and the circumplex model of affect, respectively. After consumption, the Self-Assessment Manikin (SAM) was asked to be completed.
Findings
It was observed that the valence and arousal of the emotions and affective states triggered during consumption were higher in the insect bar than in the cereal bar. Its consumption resulted in surprise and a positive evaluation. Processed insect-based foods may result in a potentially increased acceptance of this new food alternative in the market.
Originality/value
Prior studies briefly identified disgust as a primary emotion activated by insect-based food. The current research deeply studied emotional responses to insect-based processed foods in the Western world using the dimensional emotional models. This study offers arguments for the insect-based food industry to invest in processed food justified by its potential for acceptance. In addition, it motivates further research focused on other insect-based products (e.g. non-processed ones).

Abstract
Purpose
This paper seeks to broaden the agenda for environmental and ecological accounting research across several dimensions, extending the form of accounting in this field by encouraging research into its historical roots and developing a definition of accounting that can address the severe environmental and ecological challenges of the 21st century.
Design/methodology/approach
The authors explored environmental and ecological accounts from the dawn of human consciousness across a wide variety of media and in a broad range of forms. This theoretical approach reacts to the cold capitalist commodification of nature inherent in much environmental accounting practice, which documents, values and records usage of natural capital with little attempt to address depletion and loss.
Findings
By analysing the earliest ecological and environmental “accounts” recorded by humans at the dawn of human consciousness, and considering a wide array of subsequent accounts, the authors demonstrate that rather than being a secondary, relatively recent development emerging from financial accounting and reporting, environmental and ecological accounting predated financial accounting by tens of thousands of years. This research also provides a wealth of perspectives on diversity, not only in forms of account but also in the diversity of accountants, as well as the broadness of the stakeholders to whom and to which the accounts are rendered.
Research limitations/implications
The paper can be placed at the intersection of accounting history, the alternative, interdisciplinary and critical accounts literature, and environmental and ecological accounting research.
Practical implications
Practically, the authors can draw ideas and inspiration from the historical forms and content of ecological and environmental account that can inform new forms of and approaches to accounting.
Social implications
There are social implications including the diversity of accounts and accountants derived from studying historical ecological and environmental accounts from the dawn of human consciousness especially in the broadening out of the authors' understanding of the origins and cultural roots of accounting.
Originality/value
This study concludes with a new definition of accounting, fit for purpose in the 21st century, that integrates ecological, environmental concerns and is emancipatory, aiming to restore nature, revive biodiversity, conserve species and enhance ecosystems.

Abstract
Purpose
This paper aims to explore the topic of adaptive reuse referring to urban open spaces into a more-than-human perspective. It underlines that dealing with heritage means being part of an inherent and ongoing process of transformation and so that reuse is inextricably an adaptive practice, constantly facing mutations, and that adaptation is a coral practice that involves different kinds of users and makers, inclusive of human and not human livings.
Design/methodology/approach
This paper looks at the lexicon of abandonment, in search of the more essential and intense meanings of words, and at some pioneering practices in Europe to comprehend the aesthetic and ethical implications of adaptive reuse of neglected landscapes.
Findings
Processes of reuse involve many different communities of users who in turn continuously redesign the site, into a comprehensive, coral and conflicting collaboration, whose results are never given once for all and are both uncanny and beautiful, scaring and marvellous, like a monster.
Practical implications
Accepting the idea that humans are not the only users and makers of urban sites can widen the range of tools, methods and values involved in heritage adaptive reuse.
Originality/value
This paper tries to widen the meanings of adaptation into a multispecies perspective. It intends to broaden the range of agents that can be involved as users and makers, assuming a more-than-human point of view that is not yet commonly applied.
