This paper aims to present the design of a particular non-reactive test rig for combustion swirlers and first stage turbine nozzles. The test rig is required for important experimental activities aimed at the optimization of a specific class of gas turbines.

A multi-disciplinary team performed the design process by following a tailored design approach, which has been developed for the specific case. The design outcomes allowed to build a fully functional test rig to be introduced in a test cell and then to perform preliminary experiments about the fluid dynamic behaviour of the turbine elements.

The followed design approach allowed to efficiently perform the task, by supporting the information exchange among the different subjects involved in both the conceptual and the embodiment design of the test rig. Additionally, the performed experiments allowed to achieve a final configuration that makes the test rig a valuable test case for combustor-turbine interaction studies.

The study described in this paper is focused on the design of a specific test rig, used for first validation tests. However, the achieved results (both in terms of design and test) constitutes the underpinning of the in-depth investigations to be performed in the next steps of the experimental campaign.

To the best of the authors’ knowledge, the present paper is the first one that comprehensively describes the design activity of an experimental test rig for turbine application, also providing indications about the specific methodological procedure used to manage the process.

One of the most marginalized communities in India is the Lesbian, Gay, Bisexual and Transgender (LGBT) community which commonly experiences discrimination. Many studies have countered that the LGBT community faces high discrimination in the banking and financing industry. As a result, this study concentrates on this marginalized community and its acceptance and continuation habit regarding mobile wallets. Consequently, this study has considered continuance intentions as a response to confirm the progress of the mobile-wallet industry. Also, this study tried to study the relationship between behavioral intention (BI) and continuous intention (CI) which is seriously lacks in the library of literature. The research operationalized the stimulus–organism–response (SOR) framework for the conceptual model and surveyed 100 self-proclaimed members of the LGBT community in India. The analysis has been done using the partial least structure (PLS). The findings demonstrate that variables like perceived trust (PT) directly influence the BI. On the other hand, variables like perceived ease of use (PEoU), social influence (SI), and satisfaction (S) doesn’t influence BI of the LGBT Community. The main outcome was a favorable association between BI and CI. It will help the stakeholders to understand how important this new market avenue is and how it can be explored. To ensure safe and secure transactions, a group think tank composed of important parties (financial institutions, mobile-wallet providers, the government, security specialists, etc.) should make recommendations. Mobile-wallet providers will attain benefit from this study’s understanding of user categories and ability to tailor their service offers as per the community.

During the COVID-19 pandemic, lockdowns and social distancing mandates forced many young Australians to radically alter everyday interactions. Physical co-presence and embodied experience, a previously taken-for-granted dynamic of territorially embedded everyday lives, and interactions with urban surroundings, were reconfigured. Digital technology, while bringing people together for work, study, or socialising, is seen to dissolve material space, and mitigate geographic isolation. But what role does co-presence and embodied, spatially embedded experience play for young people living in the city? This chapter draws on the voices and experiences of young Australians aged 18–24 during the pandemic to clarify and understand the role of the digital in their everyday lives, how they negotiated disruptions to education, work, and managing relationships during the pandemic to articulate the relationships between digital lives and embodied experiences in the city.

Every year a huge amount of food is wasted from food production till its consumption. The activity of food wastage has become a daily routine practice and a huge portion of this loss is contributed by the consumers all around the world. With a total estimated population of 207.7m, 64 percent of the population of Pakistan is below the age of 30. The purpose of this paper is to investigate the factors that affect young consumer’s food waste behavior in a developing country context.

Data were collected in the month of Ramadan and Eid primarily by means of a web-based questionnaire. A two-step approach of structural equation modeling was used as a data analysis technique.

The findings of this research confirm the hypothesis that environmental concern and time pressure influence the attitude toward food waste reduction. The results further reveal that although attitude and injunctive norms lead toward higher intentions to reduce food waste, moral norms and perceived behavioral control do not significantly impact this intent.

This study contributes toward understanding the behavior of consumers in order to ensure the provision and execution of food waste prevention campaigns. This study has implications for policy makers and decision makers, and other stakeholders responsible for food waste reduction and environmental protection. Besides, social campaigns can be developed based on the results of this study, so as to improve the habits related to food wastage in consumers. Finally, the findings are beneficial to academics and scholars that are presently working on factors related to consumer behavior toward food waste.

Food waste behavior in young consumers from developing countries in general and from Pakistan in particular has not been analyzed before. The present study aims at analyzing some of the important predecessors of food waste behavior and thus it significantly adds to the existing body of knowledge of consumer behavior toward food waste.

Twelve percent of families in the United States have a child with a disability, yet little is known about the long-term consequences of growing up with a disabled sibling. This study builds on previous research regarding disability effects on families and offers an additional view on the linked lives of families and, in particular, siblings. Using secondary data from the National Longitudinal Survey of Youth 1979 Children and Young Adults, this study examines the odds of college completion among young adults with a disabled sibling during childhood. Specifically, I examine the gender differences among those who had a sibling with a disability. Women are more than 35% less likely to complete college if they had a disabled sibling during childhood; there is no significant difference by sibling disability status for boys. To understand whether children in low-resourced families are particularly penalized by having a disabled sibling, I examine whether various family resources attenuate the low graduation odds among those who had a disabled sibling. I find that having stably married parents during childhood largely eliminates the college completion gap between those with and without a disabled sibling. However, increases in mothers' education or family income do not attenuate the college completion gap. By identifying this gender disadvantage in college completion, this study shows that disabilities have consequences not just for disabled individuals but for their siblings as well, shining a light on a hidden cost of disability on families.

Video game streaming (VGS) is emerging as an extremely popular, highly interactive, inordinately subscribed and very dynamic form of digital media. Incorporated environmental elements, gratifications and user pre-existing attitudes in VGS, this paper presents the development of an extended model of uses and gratification theory (EUGT) for predicting users' behavior in novel technological context.

The proposed model was empirically tested in VGS context due to its popularity, interactivity and relevance. Data collected from 308 VGS users and structural equation modeling (SEM) was employed to assess the hypotheses. Multi-model comparison technique was used to assess the explanatory power of EUGT.

The findings confirmed three significant types elements in determining VGS viewers' engagement, including gratifications (e.g. involvement), environmental cues (e.g. medium appeal) and user predispositions (e.g. pre-existing attitudes). The results revealed that emerging technologies provide potential opportunities for new motives and gratifications, and highlighted the significant of pre-existing attitudes as a mediator in the gratification-uses link.

This study is one of its kind in tackling the criticism on UGT of considering media users too rational or active. The study achieved this objective by considering environmental impacts on user behavior which is largely ignored in recent UGT studies. Also, by incorporating users pre-existing attitudes into UGT framework, this study conceptualized and empirically verified the higher explanatory power of EUGT through a novel multi-modal approach in VGS. Compared to other rival models, EUGS provides a more robust explanation of users' behavior. The findings contribute to the literature of UGT, VGS and users' engagement.

The coronavirus disease (COVID-19) has increased food delivery service demand, which generates massive amounts of solid waste, specifically plastic material. Therefore, this study aims to examine the determinants of consumers' intention to reuse food delivery containers (ITR) using the extended theory of planned behavior (TPB). Moral obligation was included as an antecedent, while behavioral expectation (BE) ahead of behavioral intention was an immediate predictor of consumers' pro-environmental behaviors.

The hypotheses were tested on 348 food delivery service users in Malaysia and analyzed using the partial least squares structural equation modeling (PLS-SEM).

The findings indicated that consumers' ITR is directly influenced by perceived behavioral control and attitude. Perceived behavioral control and attitude had a positive partial indirect effect on ITR through BE. Meanwhile, subjective norms and moral obligation had a positive full indirect effect on ITR through BE.

The findings can be directly applied to practical situations of food delivery companies and environmental protection organizations managing solid waste among food delivery services.

Understanding consumers' ITR could promote practical environmental sustainability. Practically, the study provides insights to the food delivery service industry, policymakers and relevant stakeholders to encourage consumer behavior change by reusing food delivery containers in line with Sustainable Development Goal 12.

The study enhances the existing literature by extending TPB with two psychological variables: moral obligation (independent variable) and BE (mediating variable). To the best of the authors' knowledge, this study is the first attempt to empirically investigate BE in consumers' pro-environmental behavioral intention in a high-context culture and developing economy. This study could benefit food and beverage merchants, food delivery companies, governments, non-governmental organizations and pro-environmental behavior researchers in this industry.

The adverse effects on environmental sustainability, human health and animal welfare are often cited as the main reasons for reducing animal-based meat production and consumption. This study explored the food choice motives that determine consumer attitude toward plant-based meat (PBM) as a sustainable meat alternative. The theory of planned behavior (TPB) was applied to further determine whether an individual’s attitude toward PBM, subjective norms and perceived behavioral control influence their willingness to try novel meat substitutes (i.e. PBM). Finally, the moderating effect of meat attachment was also considered.

Online self-reported questionnaires were administered in Taiwan, and 294 valid questionnaires were collected. Structural equation modeling (SEM) and moderated regression were employed for analysis.

The results clarified the food choice motives that influenced consumer attitude toward PBM and revealed that attitude and subjective norms pertaining to trying PBM explained up to 35.03% of the variance in consumer willingness to try PBM. Notably, consumer meat attachment moderated the positive relationship between consumer attitude toward PBM and willingness to try PBM such that it became negative.

On the basis of the empirical findings regarding the food choice motives that influence consumer attitude and willingness to try PBM, this study provided practical implications for marketers seeking to increase consumer willingness to try PBM.

The main theoretical contribution of this research is that food choice motives should be considered in a TPB model to explain consumer willingness to try PBM. The moderating effect of consumer meat attachment should also be considered.

The purpose of this paper is to examine the effect of subjective ambivalence on ethical consumption behaviors and the role of ethical claims in reducing feelings of ambivalence toward buying ethical products.

The authors conducted two studies. In study 1, the authors carried out an online survey with a sample of 230 French consumers. The authors applied structural equation modeling with Amos to test the relationships among skepticism, ambivalence and ethical consumption behaviors. Study 2 is an experimental design in which the authors manipulated ethical claims (low – few ethical arguments vs. high – many ethical arguments) in advertising (176 French panelists). The authors tested the relationships among consumer ethical sensitivity, perceived brand ethicality, skepticism, ambivalence and intention to purchase an ethical product, depending on ethical claims in advertising.

Study 1 shows that skepticism toward advertising of ethical products amplifies feelings of ambivalence and that ambivalence reduces consumers’ willingness to adopt ethical consumption behaviors. Study 2 shows that strong claims in advertising of ethical products reduce skepticism toward advertising of ethical products and feelings of ambivalence toward buying an ethical product through perceived brand ethicality, with consumers’ ethical sensitivity positively moderating these relationships.

The two studies explore only one form of ambivalence (i.e. subjective), and the experimental study focuses on a single category of products.

The findings highlight the difficulties in promoting ethical products. Consumers need to know if a product is “really” ethical, as they may feel ambivalent toward that product. This paper shows that strong ethical claims in advertising ethical products significantly help to overcome this barrier.

Based on attribution theory and persuasion models, this research reveals how ethical claims in advertising affect feelings of ambivalence, which negatively influence consumers’ willingness to adopt ethical consumption. In addition, it follows a holistic approach to ethical consumption behaviors to explore consumers’ ambivalence.
