Uysal MS, Saavedra P, Drury J. Beyond normative and non-normative: A systematic review on predictors of confrontational collective action. BRITISH JOURNAL OF SOCIAL PSYCHOLOGY 2024; 63:1385-1409.

Abstract
This paper critically examines the normative versus non-normative distinction commonly used in collective action research. To explore the similarities and differences between antecedents of normative versus non-normative actions, we conducted a systematic review on diverse predictors of non-normative, radical and violent collective actions. We examined 37 social and political psychology studies published after 2010 and identified five recurring themes: identity, efficacy, injustice, emotions and norms. Findings exhibited significant overlaps with those predictors associated with normative collective action. Thus, a reconceptualization is needed to undermine the rigid boundaries between these action types, highlighting the intricate interplay of factors that transcend the conventional binary. Aiming to avoid conceptual ambiguity and challenge the perspective that associating particular collective actions with unwarranted violence using social norms as fixed and a priori, we propose the term 'confrontational collective action' to separate out form of action from societal approval. Through this reconceptualization, we discussed the main limitations in the literature, focusing on how studies approach normativity and efficacy and addressing the issue of decontextualization in the literature. This paper calls for a contextually informed understanding of confrontational collective action that recognizes what is seen as 'normative' can change over time through intra- and intergroup interactions.

Abstract
Meat consumption is influenced by a variety of factors including feelings of affinity towards farm animals. The goal of this study was to examine the relationship between solidarity with animals, attitudes towards the treatment of animals and antibiotics use in livestock, and pork consumption. Data were drawn from a sample of 265 respondents in the US. Correlation and mediation analyses were performed. The results indicate a moderate but positive correlation between solidarity with animals and proecological beliefs. The association between attitudes towards the treatment of farm animals, aspects of the attitudes towards antibiotic use and solidarity with animals was also positive. We also find that proecological beliefs and concerns about the treatment of farm animals negatively influenced consumption. The effect of attitudes towards antibiotic use and solidarity with animals on consumption were however fully mediated by proecological beliefs. The results suggest that social identification with animals can play a significant role in food choice. However, its effect is part of a broader connection to nature. Holistic approaches are therefore required to address livestock production practices that may be considered unnatural.

Selected plants producing mucilage: Overview, composition, and their potential as functional ingredients in the development of plant-based foods. Food Res Int 2023; 169:112822. [PMID: 37254398 DOI: 10.1016/j.foodres.2023.112822] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 03/31/2023] [Accepted: 04/11/2023] [Indexed: 06/01/2023]
Abstract
The increase in the preference for vegan and vegetarian diets is directly related to changing eating habits and the need for plant-based alternatives to animal-based products, which are better for health, due to the high content of essential amino acids and lipid profile rich in polyunsaturated fatty acids, and have lower environmental impacts. In this scenario, there is a growing demand for plant-based foods, making it necessary to find new plant-based ingredients for application in foods and beverages. Flaxseed, chia seed, and Barbados gooseberry contain mucilage, a component with potential application in plant-based products. These hydrocolloids can be used as gelling agents, texture modifiers, stabilizers, and emulsifiers in solid and semi-solid foods. This review presents the extraction, characterization, and application of flaxseed, chia seed, and Barbados gooseberry mucilage for use in plant-based foods. It was found that mucilage composition varies due to the extraction method used, extraction conditions, and geographic location of the seed or leaf. However, applications in plant-based foods are currently limited, mainly focused on applying chia mucilage in bakery products and packaging. Research on applying flaxseed and Barbados gooseberry mucilage to plant-based products is limited, though it has been shown to have potential applications in packaging. Mucilage may also increase the nutritional profile of the product and provide better technological, functional, and sensory characteristics. Therefore, because of mucilage's excellent functional and technological properties, it is a promising candidate to act as an ingredient in plant-based food products.

Abstract
In the Middle East, particularly in Saudi Arabia, the offering of a meat dish to guests is a deeply embedded cultural tradition, and a meat-based diet is the standard in Saudi Arabia. Thus, the rise of veganism and vegetarianism within Saudi Arabia is surprising and worthy of attention, as is understanding the perceptions and motivations behind this phenomenon, particularly as they relate to food and sustainability. This research was designed to investigate this emerging phenomenon and to identify key differences in dietarian identity between Saudi vegetarians and vegans using Rosenfeld and Burrow's Dietarian Identity Questionnaire. Among other results, the vegan group scored significantly higher on the prosocial motivation construct, suggesting the desire to help society as a whole is a stronger motivating factor for vegans. As well, the vegan cohort scored higher in the personal motivation category. From an environmental and public health perspective, understanding the key factors motivating individuals to adopt a vegetarian or vegan diet in a meat-based culture like Saudi Arabia can be used to encourage others to pursue more healthy and sustainable food behaviors.

Abstract
Meat production and consumption are sources of animal cruelty, responsible for several environmental problems and human health diseases, and contribute to social inequality. Vegetarianism and veganism (VEG) are two alternatives that align with calls for a transition to more ethical, sustainable, and healthier lifestyles. Following the PRISMA guidelines, we conducted a systematic literature review of 307 quantitative studies on VEG (from 1978 to 2023), collected from the Web of Science in the categories of psychology, behavioral science, social science, and consumer behavior. For a holistic view of the literature and to capture its multiple angles, we articulated our objectives by responding to the variables of "WHEN," "WHERE," "WHO," "WHAT," "WHY," "WHICH," and "HOW" (6W1H) regarding the VEG research. Our review highlighted that quantitative research on VEG has experienced exponential growth with an unbalanced geographical focus, accompanied by an increasing richness but also great complexity in the understating of the VEG phenomenon. The systematic literature review found different approaches from which the authors studied VEG while identifying methodological limitations. Additionally, our research provided a systematic view of factors studied on VEG and the variables associated with VEG-related behavior change. Accordingly, this study contributes to the literature in the field of VEG by mapping the most recent trends and gaps in research, clarifying existing findings, and suggesting directions for future research.

Abstract
Within the context of polarized societal debates (e.g. abortion, racism, climate change), scholars often assume that individuals have clear-cut positions, either in favour of or against the debated issue. However, recent work suggests that such debates can also be breeding grounds for felt ambivalence. Moving beyond previous work that mainly focused on ambivalence as internal cognitive conflict, we propose and test a social discrepancy hypothesis, which suggests that the discrepancies ambivalents perceive between and within their own opinion and the opinion of actors in their social network and society (e.g. friends, family, opinion-based groups) positively explain their levels of felt ambivalence. In doing so, we quantitatively extend recent qualitative work by examining whether these social tensions are indeed felt within. To this end, we employed a multi-survey research project (Ns = 184, 181, 187) in the context of different societal debates in the Netherlands. Supporting our hypothesis across different debates, results showed that ambivalents' perceived opinion differences in the social environment explained their felt ambivalence. This suggests that polarized societal debates offer social discrepancies that, for ambivalents at least, can facilitate an internalization of social tensions.

Abstract
Animal-based diets in Western countries are increasingly regarded as unsustainable because of their impact on human health, environmental and animal welfare. Promoting shifts toward more plant-based diets seems an effective way to avoid these harms in practice. Nevertheless, claims against the consumption of animal products contradict the ideology of the omnivorous majority known as carnism. Carnism supports animal-product consumption as a cherished social habit that is harmless and unavoidable and invalidates minorities with plant-based diets: vegetarians and vegans (veg*ns). In this theoretical review, we integrate socio-psychological and empirical literature to provide an identity-based motivational account of ideological resistance to veg*n advocacy. Advocates who argue against the consumption of animal products often make claims that it is harmful, and avoidable by making dietary changes toward veg*n diets. In response, omnivores are likely to experience a simultaneous threat to their moral identity and their identity as consumer of animal products, which may arouse motivations to rationalize animal-product consumption and to obscure harms. If omnivores engage in such motivated reasoning and motivated ignorance, this may also inform negative stereotyping and stigmatization of veg*n advocates. These "pro-carnist" and "counter-veg*n" defenses can be linked with various personal and social motivations to eat animal products (e.g., meat attachment, gender, speciesism) and reinforce commitment to and ambivalence about eating animal products. This does not mean, however, that veg*n advocates cannot exert any influence. An apparent resistance may mask indirect and private acceptance of advocates' claims, priming commitment to change behavior toward veg*n diets often at a later point in time. Based on our theoretical account, we provide directions for future research.

Abstract
Background The link between mental health difficulties and terrorist behaviour has been the subject of debate for the last 50 years. Studies that report prevalence rates of mental health difficulties in terrorist samples or compare rates for those involved and not involved in terrorism, can inform this debate and the work of those responsible for countering violent extremism. Objectives To synthesise the prevalence rates of mental health difficulties in terrorist samples (Objective 1-Prevalence) and prevalence of mental health disorders pre-dating involvement in terrorism (Objective 2-Temporality). The review also synthesises the extent to which mental health difficulties are associated with terrorist involvement compared to non-terrorist samples (Objective 3-Risk Factor). Search Methods Searches were conducted between April and June 2022, capturing research until December 2021. We contacted expert networks, hand-searched specialist journals, harvested records from published reviews, and examined references lists for included papers to identify additional studies. Selection Criteria Studies needed to empirically examine mental health difficulties and terrorism. To be included under Objective 1 (Prevalence) and Objective 2 (Temporality), studies had to adopt cross-sectional, cohort, or case-control design and report prevalence rates of mental health difficulties in terrorist samples, with studies under Objective 2 also needing to report prevalence of difficulties before detection or involvement in terrorism. For Objective 3 (Risk Factor) studies where there was variability in terrorist behaviour (involved vs. not involved) were included. Data Collection and Analysis Captured records were screened in DisillterSR by two authors. Risk of bias was assessed using Joanna Briggs Institute checklists, and random-effects meta-analysis conducted in Comprehensive Meta-Analysis software. Results Fifty-six papers reporting on 73 different terrorist samples (i.e., studies) (n = 13,648) were identified. All were eligible for Objective 1. Of the 73 studies, 10 were eligible for Objective 2 (Temporality) and nine were eligible for Objective 3 (Risk Factor). For Objective 1, the life-time prevalence rate of diagnosed mental disorder in terrorist samples (k = 18) was 17.4% [95% confidence interval (CI) = 11.1%-26.3%]. When collapsing all studies reporting psychological problems, disorder, and suspected disorder into one meta-analyses (k = 37), the pooled prevalence rate was 25.5% (95% CI = 20.2%-31.6%). When isolating studies reporting data for any mental health difficulty that emerged before either engagement in terrorism or detection for terrorist offences (Objective 2: Temporality), the life-time prevalence rate was 27.8% (95% CI = 20.9%-35.9%). For Objective 3 (Risk Factor), it was not appropriate to calculate a pooled effect size due the differences in comparison samples. Odds ratios for these studies ranged from 0.68 (95% CI = 0.38-1.22) to 3.13 (95% CI = 1.87-5.23). All studies were assessed as having high-risk of bias which, in part, reflects challenges conducting terrorism research. Author's Conclusions This review does not support the assertion that terrorist samples are characterised by higher rates of mental health difficulties than would be expected in the general population. Findings have implications for future research in terms of design and reporting. There are also implications for practice with regards the inclusion of mental health difficulties as indicators of risk.

Abstract
Why might some meat-eaters and meat-avoiders express negative attitudes toward each other? We investigated intergroup attitudes and potential underpinnings of these attitudes across three different dietary groups—veg*ans (vegetarians and vegans), flexitarians (people who restrict their meat intake partially), and meat-eaters—in Turkey ( NStudy 1 = 366; NStudy 2 = 450). In both studies, veg*ans showed the greatest ingroup favouritism and reported the highest ingroup identification and perceived discrimination. Meat enjoyment, moral consideration, and perceived veg*an threat (among meat-eaters) predicted dietary ingroup identification in Study 1, whereas perceived discrimination towards one’s dietary group was the strongest predictor of identification among all dietary groups in Study 2. Among meat-avoiders, but not among meat-eaters, stronger dietary ingroup identification was associated with more negative outgroup attitudes. Findings are discussed in light of social identity theories and intergroup perspectives.

Abstract
In recent years, and in the current climate crisis, the interest in veganism and sustainable diet/lifestyle has increased. This growing interest can also be seen within academia. Therefore, we set out to systematically document and organize the social psychological literature on veganism and vegan identity to identify where the field currently is, and what we need to do next. Following PRISMA guidelines we identified a data set of 26 academic papers published between 2010 and 2021. Through a thematic analysis of the data, we created four categories of study focus and content: (1) vegans as a disadvantaged/stigmatized group, (2) the role of ideology in negative attitudes toward vegans, (3) the role of moral and ethical beliefs in changing or sustaining dietary preferences, and (4) veganism as a social movement and vegan activism. Our analysis emphasizes issues with merging all non-meat eaters, reduction of veganism into dietary or lifestyle choices neglecting the politicized content and movement, lack of processes underlying emergence and endurance of veganism, and decontextualization of vegan identity. What is needed is a more fine-grained exploration that addresses the identified issues to account for the content of vegan identity. This would expand, for example, the motives literature to include and emphasize intersectionality in a vegan identity context. Specifically, to facilitate a more sustainable lifestyle, the content of social dimensions needs to be qualitatively explored.

Abstract
Transport by land is an essential component for the commercialization of fattening pigs and can have a negative impact on animal welfare. In slaughterhouses, the presence of dead and non-ambulatory animals is an indicator of poor welfare during transport. The objective of the study was to identify risk factors associated with the frequency of dead and non-ambulatory pigs during transport. A survey was conducted in three Colombian slaughterhouses. Data were collected from 372 batches (n = 18,437 gilts barrows) and transported directly from the farms to the slaughterhouses. Each truck was individually evaluated; a structured survey was administered to drivers, non-ambulatory and dead pigs on arrival were identified and blood samples were obtained from non-ambulatory pigs to assess physiological indicators of stress. Mortality rates per batch at arrival ranged from 0.08 to 0.17% and prevalence of non-ambulatory pigs per batch ranged from 0.84 to 1.37%.The results of the multilevel mixed effects linear regression model identified the following as risk factors associated with the frequency of total transport losses: truck speed (P = 0.04), distance (P < 0.01), transport time (P < 0.01), load size (P < 0.01) and the driver (P < 0.01) including the farm as a fixed effect. This study identified risk factors that increased the probability of total transport losses during land transport under Colombian commercial conditions. But more research that involves commercial drivers is needed to develop effective strategies to improve Colombian pig's transportation chain.

Abstract
Social change occurs over years and decades, yet we know little about how people sustain, increase or diminish their actions over time, and why they do so. This article examines diverging trajectories of solidarity-based collective action to support people in developing nations more than 5 years. We suggest that sustained, diminished, and/or increased action over time will be predicted by identification as a supporter, group efficacy beliefs, and discrete emotions about disadvantage. Latent Growth Mixture Models (N = 483) revealed two trajectories with unique signatures: an activist supporter trajectory with a higher intercept and weakly declining action; and a benevolent supporter trajectory with a lower intercept but weakly increasing action. The activist trajectory was predicted by social identification, outrage, and hope, whereas the benevolent supporter trajectory was predicted by sympathy. The results highlight the role of combinations of emotions and the need for person-centered longitudinal methods in collective action research.

Judge M, Fernando JW, Begeny CT. Dietary behaviour as a form of collective action: A social identity model of vegan activism. Appetite 2021; 168:105730. [PMID: 34619244 DOI: 10.1016/j.appet.2021.105730] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Revised: 07/08/2021] [Accepted: 09/30/2021] [Indexed: 01/09/2023]
Abstract
Adopting plant-based, or vegan, diets can have a number of benefits, including mitigating climate change, promoting animal welfare, or improving public health. In the current research, we use social psychological theory to better understand what motivates vegans to engage in collective action on behalf of this social group - that is, what motivates individuals to promote, or encourage others to adopt, a vegan lifestyle. We develop and test a Social Identity Model of Vegan Activism, which highlights the roles of individuals' social identities, sense of efficacy, emotions and moral convictions in fostering collective action. In two pre-registered studies, the first with self-identified vegans from Australia and the UK (N = 351), and the second with self-identified vegans from the UK and the US (N = 340), we found that individuals more frequently engaged in vegan activism (i.e., actions to promote vegan lifestyles) when they had stronger moral convictions (i.e., deontological or consequentialist), greater collective efficacy (i.e., beliefs that vegans can make a positive difference), anger (i.e., when thinking about the reasons why they are vegan), and identification (both with vegans, and with animals). Deontological and consequentialist moral convictions had significant indirect effects on vegan activism via different mediators. We conclude by discussing the implications and importance of studying dietary behavior from a social identity perspective, including its ability to help explain how and why individuals become motivated to not only adopt a certain (e.g., vegan) lifestyle themselves, but to also 'act collectively' on behalf of that shared group membership (e.g., promote vegan-friendly behaviors). We also highlight some key insights for policy makers and campaigners aiming to promote plant-based diets.

De Groeve B, Rosenfeld DL. Morally admirable or moralistically deplorable? A theoretical framework for understanding character judgments of vegan advocates. Appetite 2021; 168:105693.

Abstract
Over the last decade, vegan advocates have become a growing minority. By arguing against animal-product consumption and imposing the virtue-loaded call to "go vegan," advocates have posed a direct challenge to the mainstream dietary ideology (termed "carnism") in hopes of positive social change. As a consequence, while vegan advocates may be admired for their morality and commitment, they may also be derogated with moralistic traits such as arrogance and overcommitment. We call this mixed-valence perception the "vegan paradox" and propose a theoretical framework for understanding it. Next, we develop a future research agenda to test and apply our framework, and inquire vegan advocacy for ethical, health, and environmental aims. Using the perspective of the idealistic vegan advocate as a reference point, we discuss the roles of the advocate's motives for change (i.e., the effectiveness of moral persuasion), the advocate's call for change (i.e., radical versus incremental change), the target's moral and carnist identification, and source attributes of the advocate. Lastly, we qualify our framework by highlighting further conceptual and methodological considerations.

Abstract
People are motivated by shared social values that, when held with moral conviction, can serve as compelling mandates capable of facilitating support for ideological violence. The current study examined this dark side of morality by identifying specific cognitive and neural mechanisms associated with beliefs about the appropriateness of sociopolitical violence, and determining the extent to which the engagement of these mechanisms was predicted by moral convictions. Participants reported their moral convictions about a variety of sociopolitical issues prior to undergoing functional MRI scanning. During scanning, they were asked to evaluate the appropriateness of violent protests that were ostensibly congruent or incongruent with their views about sociopolitical issues. Complementary univariate and multivariate analytical strategies comparing neural responses to congruent and incongruent violence identified neural mechanisms implicated in processing salience and in the encoding of subjective value. As predicted, neuro-hemodynamic response was modulated parametrically by individuals' beliefs about the appropriateness of congruent relative to incongruent sociopolitical violence in ventromedial prefrontal cortex, and by moral conviction in ventral striatum. Overall moral conviction was predicted by neural response to congruent relative to incongruent violence in amygdala. Together, these findings indicate that moral conviction about sociopolitical issues serves to increase their subjective value, overriding natural aversion to interpersonal harm.

Abstract
Although political action often requires activists to express who they are and what they stand for, little is known about the motivators of such identity expression. This research investigates how group identity content and identification with this content predict identity-expressive collective action in the U.S. 2016 presidential elections. We recruited a longitudinal community sample of U.S. party supporters (N = 426) mid-October (T1), beginning November (T2), and mid-November (T3). Participants listed words they associated with party campaigners, and self-reported their identification with this identity content and the politicized group. Supporting H1, politicized group identification longitudinally predicted increased frequency of collective action more strongly than did identification with specific identity content. Supporting H2, identification with specific identity content longitudinally predicted increased desires to express that content through collective action more strongly than politicized group identification. Implications for our understanding of identity expression and identity content in collective action are discussed.

Abstract
People deeply value their social bonds with companion animals, yet routinely devalue other animals, considering them mere commodities to satisfy human interests and desires. Despite the inherently social and intergroup nature of these complexities, social psychology is long overdue in integrating human-animal relations in its theoretical frameworks. The present body of work brings together social psychological research advancing our understanding of: 1) the factors shaping our perceptions and thinking about animals as social groups, 2) the complexities involved in valuing (caring) and devaluing (exploiting) animals, and 3) the implications and importance of human-animal relations for human intergroup relations. In this article, we survey the diversity of research paradigms and theoretical frameworks developed within the intergroup relations literature that are relevant, perchance critical, to the study of human-animal relations. Furthermore, we highlight how understanding and rethinking human-animal relations will eventually lead to a more comprehensive understanding of many human intergroup phenomena.

Abstract
Concerns raised, including those voiced by animal rights and vegan activists, have limited the available practices by landholders in the southern Australian rangelands to effectively control kangaroos and, over time, the actions of these groups may threaten the existence of the livestock industry. This paper draws on interviews with key stakeholders and workshops with technical experts and red meat industry participants to identify strategies to respond to this potentially existential threat. Strategies include establishing platforms and processes for effective stakeholder engagement, establishing a unified and resourced industry ‘voice’ to effectively engage with government and other stakeholders, and ensuring that the industry self-regulates in order to avoid the potential for rogue elements to undermine its credibility and trustworthiness.
