The effects of self-efficacy and collective efficacy on customer food waste reduction intention: the mediating role of ethical judgment
Authors: Ding Li 
Published: May 2022

PurposeThis study aims to (1) examine the effects of restaurant customer self-efficacy and perceived collective efficacy toward food waste reduction on their food waste reduction intention (FWRI), and (2) explore the mediating role of customer ethical judgment toward restaurant food waste reduction behavior in the relationship between efficacy and food waste reduction intention.Design/methodology/approachData were collected through an online survey. The responses from 428 US restaurant customers were used for data analysis. Partial least squares structural equation modeling (PLS-SEM) was employed to examine the path effects.FindingsThe study found that restaurant customer self-efficacy and perceived collective efficacy toward food waste reduction positively influenced their FWRI. These relationships were mediated by customers’ ethical judgment.Practical implicationsRestaurant practitioners are recommended to allocate resources to food waste reduction programs and make customers aware of the efforts they have dedicated. Customer FWRI can be increased if they judge such initiatives as highly ethical. The restaurant practitioners should also be aware of the distinct associations between customer self-efficacy and perceived collective efficacy and their ethical judgment.Originality/valueThis is the first study to discuss the roles of customer self-efficacy, perceived collective efficacy and ethical judgment toward food waste reduction in determining FWRI. The proposed framework enriches social cognitive theory and self-regulation theory. The results especially underscore the mediating role of customers’ ethical judgment.
Knowledge transfer, buyer-supplier relationship and supplier performance in agricultural supply chain: an agency theory perspective
Authors: Shukla Suwarna , Kapoor Rohit , Gupta Narain , Arunachalam Deepak 
Published: May 2022

Purpose
This paper aims to examine the performance of marginalized farmers in supply relationships with agri-tech firms in emerging rural agricultural economies. The complex relationship among the suppliers, dual relationship and knowledge transfer (KT) was studied. This paper empirically investigates the relationship between KT and supplier’s performance improvement (SPI) via buyer–supplier relationship (BSR).

Design/methodology/approach
Grounded on agency theory, a conceptual framework has been proposed to identify the mediation effect of BSR. The context deals with suppliers who are farmers in developing nations. The hypotheses were tested using confirmatory factor analysis and structural equation with a sample of 121 marginalized farmers from Indian states. The data was collected using a survey instrument designed by adapting the well-cited and validated measures. These marginalized farmers worked in collaboration with the agri-tech firms facilitating them with the KT.

Findings
The relationships established from the results also indicate the fact that KT is a powerful tool to make connections with farmers that lead to their performance improvement. The KT was found as a driver to improve performance (SPI) and the BSR acted as a positive mediator in this study. The complex relationships among the KT, BSR and SPI hold.

Research limitations/implications
This paper can be subscribed to various nuanced understandings of the agricultural supply chain context in emerging economies, in the specialized cases where farmers belong to the marginalized communities. This study has the scope to replicate using a mixed-method approach in emerging economies beyond India. It also advances the agency theory literature in the supply chain discipline of emerging rural economies.

Practical implications
This study offers strategic implications for agri-tech practitioners, policymakers and academic debate. The marginalized farmers with KT and improved BSR can become a part of the mainstream value chain, their debts can be reduced, suicides can be prevented and the quality of their family life can be significantly improved.

Originality/value
This study makes a unique contribution by investigating how the agri-tech firms (non-traditional buyer) and supplier relationship and KT helps improve the economic sustainability of smallholder farmers in India. The authors immersed themselves in fieldwork by interacting and meeting in person with 121 farmers residing in the remotest of the remote rural areas across multiple states of India. This resulted in the collection of authentic data and capturing the ground realities from one of the fastest-growing and largest emerging economies.
Acculturation preferences, conflict and cultural enrichment on secondary education in Western Catalonia
Authors: Lapresta-Rey Cecilio , Hinostroza-Castillo Ursula , Senar Fernando , Ianos Maria Adelina 
Published: May 2022

Purpose
Located in Western Catalonia (Spain), the article’s aim is to analyse the acculturation preferences of majority group high-school students towards their peers of Moroccan and Romanian descent. Furthermore, it aims to delve deeper into the influence on the perception of conflict with these groups mediated by cultural enrichment.

Design/methodology/approach
The data are the result of conducting a questionnaire among 349 autochthonous students enrolled in Compulsory Secondary Education in Catalonia. The data have been analyzed using cluster analysis, ANOVA and mediation analysis.

Findings
The findings show that a small number of high-school students construct integration acculturation preferences towards Moroccans and Romanians, while the majority of the preferences are of assimilation or segregation. In addition, the perceived conflict is higher for Moroccans than Romanians, and the cultural enrichment is higher for Romanians than for Moroccans. Finally, there is a low mediating effect of cultural enrichment on the relationship between acculturation preferences and degree of conflict.

Originality/value
The relevance and originality of this article stems from the application of acculturation theory on the construction of acculturation preferences in the educational domain. Additionally, it is a context characterized by an exceptional cultural and linguistic diversity. Furthermore, acculturation preferences, perceived degree of conflict and perceived cultural enrichment are analyzed comparatively regarding descendants of Moroccans and Romanians. This approach has scarcely been used at an international level, and practically never at the Spanish and Catalan level.

The evolving legitimacy of external quality assurance in Colombian higher education
Authors: Duque Juan Felipe 
Published: May 2022

Purpose
This paper aims to analyze how the legitimacy of the policy of external quality assurance (EQA) in Colombian higher education has evolved over the past 30 years through an examination of its two main instruments: the compulsory control of minimum quality standards for academic programs and institutions (registro calificado) and accreditations of excellence for programs and institutions.

Design/methodology/approach
Based on the methodology of process-tracing, this paper offers a review of the main sequences of the policy of EQA in Colombian higher education: the origins (1990–1998), the expansion (1998–2011) and the contestation (2011–2021). In each sequence, the sources of the substantive and procedural legitimacy of the policy are analyzed. This analysis is based on qualitative data comprising semi-structured interviews with key informants, online information from the 2011 and 2018 student protests and official documentation.

Findings
The policy of EQA in Colombian higher education had relatively high levels of substantive and procedural legitimacy during the first two sequences. However, the situation has become more ambivalent since 2011. On the one hand, internal contradictions and student movements’ growing criticism of neoliberal policies have undermined some of the foundations of this policy. On the other hand, higher education institutions and the Colombian Government still have a positive perception of EQA and have recently revisited the policy to address some of its shortcomings.

Originality/value
From a conceptual standpoint, this paper advances our understanding of how quality assurance in higher education gains, sustains or loses legitimacy by discussing and testing typologies of legitimacy in the analysis of a national system of EQA. From an empirical perspective, this paper provides a diachronic analysis of EQA in Colombian higher education, a case that has primarily been studied through a technical-rational perspective.

Authors: Mehta Pooja , Kaur Amarjit , Singh Sandeep , Mehta Minakshi Duggal 
Published: May 2022

PurposeThe purpose of this study is to examine relationship between numerous factors (fashion orientation, conspicuous consumption and environmental consciousness) that influence fast fashion (FF) purchase intention and their impact on FF purchase behavior and exploring the moderating effect of sustainable clothing consumption attitude.Design/methodology/approachThis study uses quantitative analysis approach, wherein data have been collected from 571 college students by using non-probability snowball sampling. Partial least square structural equation modeling (PLS-SEM) has been applied to analyze the relationships among variables.FindingsDeterminants fashion orientation and conspicuous consumption have substantial impact on the desire to buy FF, which has strong association with FF purchasing behavior. Environmental awareness, contrarily, has detrimental impact on FF purchasing intentions. Furthermore, sustainable clothing consumption attitude significantly moderates FF intention–behavior relationship.Practical implicationsFindings may be viewed as a driving course in textile and garment sector for entrepreneurs as they represent customers’ intents and behavior in connection to the adoption of FF. Strategists can understand the product’s lifecycle; marketers can define innovative ways of marketing, advertising and promotion; start-ups can look for opportunities in sustainable fashion industry by innovating, manufacturing and dealing in eco-friendly sustainable products; and policymakers can make suitable policies to create awareness regarding sustainable fashion.Originality/valueTo the best of the authors’ knowledge, there is no study that comprehensively deals with defining, structuring and validating factors affecting purchase intention and behavior in case of fashion industry, accompanied by the role of sustainable consumption attitude as a moderator between FF intention and behavior, in a single model.
Enhancing the resolution of seismic data based on the non‐local similarity
Authors: Chen Siyuan , Cao Siyuan , Sun Yaoguang 
Published: May 2022

ABSTRACTWe propose a resolution‐enhancement method based on the non‐local similarity of the seismic profile. Because of the similarity in underground structures, the seismic data have similar event structures in different regions. We introduce the similarity as prior information to enhance the resolution of seismic data. The similarity, as a regularization term for enhancing the resolution, can improve the stability of the solution. The non‐local similarity constraint is usually implemented based on nuclear norm minimization. We use the L1–L2 norm instead of the L1 norm in the nuclear norm, which will obtain a more accurate approximation of low rank. Compared with the deconvolution algorithm based on the L2 norm, we use non‐local similarity as a constraint term. The proposed method can enhance the resolution with a low signal‐to‐noise ratio, suppress random noise and improve lateral continuity. The synthetic and field data prove the superiority of the proposed method for low signal‐to‐noise ratio data.

SummarySince the beginning of the pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) the gastrointestinal (GI) tract has emerged as an important organ influencing the propensity to and potentially the severity of the related COVID‐19 disease. However, the contribution of the SARS‐CoV‐2 intestinal infection on COVID‐19 pathogenesis remains to be clarified. In this exploratory study, we highlighted a possible link between alterations in the composition of the gut microbiota and the levels of SARS‐CoV‐2 RNA in the gastrointestinal tract, which could be more important than the presence of SARS‐CoV‐2 in the respiratory tract, COVID‐19 severity and GI symptoms. As established by metaproteomics, altered molecular functions in the microbiota profiles of high SARS‐CoV‐2 RNA level faeces highlight mechanisms such as inflammation‐induced enterocyte damage, increased intestinal permeability and activation of immune response that may contribute to vicious cycles. Uncovering the role of this gut microbiota dysbiosis could drive the investigation of alternative therapeutic strategies to favour the clearance of the virus and potentially mitigate the effect of the SARS‐CoV‐2 infection.

Published: May 2022

AbstractAimTo determine the proportion of research projects funded by the National Health and Medical Research Council and Australian Research Council research funding from 2014 to 2021 that aimed to understand or improve dietary behaviours for at‐risk populations in Australia and estimate the proportion of total funding allocated during this period.MethodsRetrospective analysis of the publicly available National Health and Medical Research Council and Australian Research Council funding grants over the 8 years from 2014 to 2021 (n = 18 098). At‐risk dietary populations included people living in rural and remote Australia, Aboriginal and Torres Strait Islander people, or people living in socioeconomically disadvantaged areas. Descriptive analysis was undertaken.ResultsIn total, 144 out of 18 098 (0.8%) individual grants totalling $96.8 million were identified relating to nutrition research from 2014 to 2021. Out of the 144, only 21 ($19.6 million; 0.1%) of all National Health and Medical Research Council grants were identified for nutritionally at‐risk populations, with the majority focused on Aboriginal and Torres Strait Islander people (15/21). The National Health and Medical Research Council and Australian Research Council grants that aimed to improve human dietary behaviours increased by 0.66% and 0.58%, respectively, from 2014 to 2021. However, the National Health and Medical Research Council grants aiming to improve nutritional behaviours in at‐risk populations decreased by 0.04% over the 8 years.ConclusionsDespite slight increases in the proportions of funding to improve dietary behaviours over the past decade, nutrition research specifically targeting at‐risk groups is scarce and appears to have decreased over time. Insufficient investment in research for these groups presents a risk for widening health disparities now and into the future. As such, they must be further supported and considered in the design of future funding schemes.

AbstractObjectiveComorbidities contribute both to morbidity and mortality in rheumatoid arthritis (RA). The aim of the current study was to investigate the prevalence and spectrum of comorbidities in South Africans with established RA.MethodsA retrospective, consecutive case record review of 500 Black South African patients with established disease of ≥5 years attending a tertiary rheumatology service was performed. Common comorbidities including those listed in the Charlson Comorbidity Score (CCS) were documented.ResultsMost patients, 463 known alive (AG) and 37 known deceased (DG), were female (87%). Mean (SD) age and disease duration were 60 (11.1) and 10.7 (5.0) years respectively, and 98% had ≥1 comorbidities. Median CCS was 2, significantly higher in DG than AG (4 vs 2, P < .0001). Despite hypertension (70%) and hypercholesterolemia (47%) being the commonest comorbidities overall and type 2 diabetes (T2D) occurring in 15.4%, clinical cardiovascular events were rare (0.6%). Peptic ulcer disease (odds ratio [OR] = 8.67), congestive cardiac failure (OR = 7.09), serious infections (OR = 7.02) and tuberculosis (OR = 2.56) were significantly more common in DG than AG. Multivariate analysis showed that American College of Rheumatology functional class 3/4 was associated with increased risk for serious infections (OR = 3.84) and tuberculosis (OR = 2.10).ConclusionDespite the high burden of cardiometabolic comorbidities in South Africans with established RA, cardiovascular events were rare. Serious infections and tuberculosis, both associated with severe functional disability, are a major cause of morbidity and mortality.

Abstract

Growing interest and affordability of environmental DNA and RNA (eDNA and eRNA) approaches for biodiversity assessments and monitoring of complex ecosystems have led to the emergence of manifold protocols for nucleic acids (NAs) isolation and processing. Although there is no consensus on a standardized workflow, the common practice for water samples is to concentrate NAs via filtration using varying pore size membranes. Using the smallest pore is assumed to be most efficient for NAs capture from a wide range of material (including sub‐cellular particles); however, a trade‐off must occur between detection of a meaningful molecular signal and cost/time effort when processing samples using fine pore membranes.

Comparative studies involving formal efficiency assessments are lacking, which restricts informed decision‐making around an optimized sampling approach for applications such as biosurveillance (i.e. detection and monitoring of target taxa—nuisance organisms, endangered and indicator taxa or other species of economic or cultural importance). Here, we present an experimental study using an easily cultured microalgal species (Alexandrium pacificum) to test different filter membranes for capturing NAs in the context of cost/time effort and cell fractions encountered in nature (whole cells, partially lysed and naked NAs).

The results showed no statistically significant difference between membrane types for capturing target eDNA signal from intact and partially lysed cell treatments. In terms of time effort and volume processed, higher efficiency ratings were obtained with the larger pore size (5 μm) cellulose membranes. Positively charged nylon demonstrated enhanced capture of naked NAs, and especially eRNA signal, across treatments.

Our findings support using coarse pore size filters for adequate capture of target NA signal (from both eDNA and eRNA) with less processing time. The framework presented here can provide a quick and robust feasibility check and comparative assessment of new and existing NA processing technologies, and allows sufficient control over multiple parameters, including physical–chemical water properties, temporal scales, and concentration and type of input material.
