RESUMO

How accurate are Americans' perceptions of the material benefits associated with union membership, and do these perceptions influence their support for, and interest in joining, unions? We explore these questions in a preregistered, survey experiment conducted on a national sample, representative of the US population on a number of demographic benchmarks (n = 1,430). We find that Americans exhibit large and consistent underestimates of the benefits associated with unionization, as compared to evidence from the Bureau of Labor Statistics and peer-reviewed academic research. For example, 89% of Americans underestimated the life-time income premium associated with union membership, 72% underestimated the percentage of union members who receive health insurance from their employer, and 97% overestimated the average union dues rate. We next randomly assigned half of the participants to receive a brief, informational correction conveying results of academic and government research on the material benefits associated with union membership, or not. Those who received the correction reported 11.6% greater interest in joining a union, 7.8% greater support for unions, and 6.9% greater interest in helping to organize a union in their workplace, as compared to the control group. These results suggest that, overall, Americans tend to underestimate the material benefits associated with unionization, misperceptions of these benefits are causally linked to Americans' support for unionization, and correcting these misperceptions increases a range of pro-union sentiments in the American mass public.

RESUMO

Recent work finds that nonviolent resistance by ethnic minorities is perceived as more violent and requiring more policing than identical resistance by ethnic majorities, reducing its impact and effectiveness. We ask whether allies-advantaged group participants in disadvantaged group movements-can mitigate these barriers. On the one hand, allies can counter negative stereotypes and defuse threat perceptions among advantaged group members, while raising expectations of success and lowering expected risks among disadvantaged group members. On the other hand, allies can entail significant costs, carrying risks of cooptation, replication of power hierarchies, and marginalization of core constituencies. To shed light on this question we draw on the case of the Black Lives Matter (BLM) movement, which, in 2020, attracted unprecedented White participation. Employing a national survey experiment, we find that sizeable White presence at racial justice protests increases protest approval, reduces perceptions of violence, and raises the likelihood of participation among White audiences, while not causing significant backlash among Black audiences. Black respondents mostly see White presence as useful for advancing the movement's goals, and predominant White presence reduces expectations that protests will be forcefully repressed. We complement these results with analysis of tens of thousands of images shared on social media during the 2020 BLM protests, finding a significant association between the presence of Whites in the images and user engagement and amplification. The findings suggest that allyship can be a powerful tool for promoting sociopolitical change amid deep structural inequality.

RESUMO

Social media's pivotal role in catalyzing social movements is widely acknowledged across scientific disciplines. Past research has predominantly explored social media's ability to instigate initial mobilization while leaving the question of its capacity to sustain these movements relatively uncharted. This study investigates the persistence of movement activity on Twitter and Gab following a substantial on-the-ground mobilization event catalyzed by social media-the StoptheSteal movement culminating in the January 6th Capitol attack. Our findings indicate that the online communities active in the January 6 mobilization did not display substantial remobilization in the subsequent year. These results highlight the fact that further exploration is needed to understand the factors shaping how and when movements are sustained by social media. In this regard, our study provides valuable insights for scientists across diverse disciplines, on how certain social media platforms may contribute to the evolving dynamics of collective action.

RESUMO

SignificanceThe effects of recent protests for racial equality, particularly when they included violence, are currently of public and academic interest. To better understand these effects, we combine a dataset of all 2020 BlackLivesMatter protests with survey data containing measures of prejudice and support for police reform. Protests were not associated with reductions in prejudice, but were associated with increases in support for police reform. Specifically, a mix of nonviolent and violent protests was associated with an increase in police-reform support among conservatives living in liberal areas. This study highlights the importance of considering multiple measures of protest effectiveness and suggests that mass protest (including when it mixes nonviolence and violence) can be effective at advancing the movement's goals.

RESUMO

Cooperation usually becomes harder to sustain as groups become larger because incentives to shirk increase with the number of potential contributors to collective action. But is this always the case? Here we study a binary-action cooperative dilemma where a public good is provided as long as not more than a given number of players shirk from a costly cooperative task. We find that at the stable polymorphic equilibrium, which exists when the cost of cooperation is low enough, the probability of cooperating increases with group size and reaches a limit of one when the group size tends to infinity. Nevertheless, increasing the group size may increase or decrease the probability that the public good is provided at such an equilibrium, depending on the cost value. We also prove that the expected payoff to individuals at the stable polymorphic equilibrium (i.e., their fitness) decreases with group size. For low enough costs of cooperation, both the probability of provision of the public good and the expected payoff converge to positive values in the limit of large group sizes. However, we also find that the basin of attraction of the stable polymorphic equilibrium is a decreasing function of group size and shrinks to zero in the limit of very large groups. Overall, we demonstrate non-trivial comparative statics with respect to group size in an otherwise simple collective action problem.

RESUMO

The intricate interplay between the state and society may foster opposition and prompt collective action as a mode of protest. When the state responds repressively to such collective action, it aims to undermine it escalating its costs. A mathematical model relating the repressive response to collective action, articulated through differential equations, facilitates a thorough analysis of their dynamic interaction. Modeling outcomes indicate that repressive regimes may exhibit sustained persistence, oscillatory patterns, or destabilization, potentially transitioning into alternative regimes. This modeling framework offers a means to discern the impact of diverse factors on the dynamics of repressive regimes and to provide modelling insight on the emergence of cycles of protest observed in different countries during certain periods of their history.

RESUMO

ACADEMIC ABSTRACT: In this narrative review, we examined 134 studies of the relationship between intergroup contact and collective action benefiting disadvantaged groups. We aimed to identify whether, when, and why contact has mobilizing effects (promoting collective action) or sedative effects (inhibiting collective action). For both moderators and mediators, factors associated with the intergroup situation (compared with those associated with the out-group or the in-group) emerged as the most important. Group status had important effects. For members of socially advantaged groups (examined in 98 studies, 100 samples), contact had a general mobilizing effect, which was stronger when contact increased awareness of experiences of injustice among members of disadvantaged groups. For members of disadvantaged groups (examined in 49 studies, 58 samples), contact had mixed effects. Contact that increased awareness of injustice mobilized collection action; contact that made the legitimacy of group hierarchy or threat of retaliation more salient produced sedative effects. PUBLIC ABSTRACT: We present a review of existing studies that have investigated the relationship between intergroup contact and collective action aimed at promoting equity for disadvantaged groups. We further consider the influence of contact that is positive or negative and face-to-face or indirect (e.g., through mass or social media), and we distinguish between collective action that involves socially acceptable behaviors or is destructive and violent. We identified 134 studies, considering both advantaged (100 samples) and disadvantaged groups (58 samples). We found that intergroup contact impacts collective action differently depending on group status. Contact generally leads advantaged groups to mobilize in favor of disadvantaged groups. However, contact has variable effects on members of disadvantaged groups: It sometimes promotes their collective action in support of their own group; in other cases, it leads them to be less likely to engage in such action. We examine when and why contact can have these different effects.

RESUMO

ACADEMIC ABSTRACT: Advantaged group allies have multiple motives for supporting equality, raising questions about their sincerity. We draw upon the covariation model of attributions to explain how disadvantaged group members make attributions about whether advantaged group "allies" are sincerely motivated to empower the disadvantaged group. We propose an Attribution-Identity Model of Sincerity (AIMS) which posits that disadvantaged group members view advantaged group members as sincere allies when they support equality in the presence of inhibitory causes and in the absence of facilitative causes, exceed expectations for the advantaged group, and provide support across time and contexts. Furthermore, those who identify strongly with their disadvantaged group and perceive intergroup inequality as illegitimate are most motivated to ascertain the sincerity of advantaged group members' allyship. AIMS suggests how members of disadvantaged groups seek to maximize benefits and minimize risks of advantaged group members' allyship. PUBLIC ABSTRACT: Advantaged group members (e.g., men, White Americans) can act as allies for disadvantaged groups (e.g., women, Americans belonging to minoritized racial groups), but members of disadvantaged groups sometimes have reason to question whether their motives are sincere. We argue that members of disadvantaged groups view advantaged group allies as more sincere when they support equality when they do not stand to benefit from it and even when they stand to lose. We also argue that members of disadvantaged groups view advantaged group allies as more sincere when their support for equality goes beyond expectations for their advantaged group, consistently over time, and is not limited to particular situations, forms, or contexts. Members of disadvantaged groups like sincere allies, want to work with them, and feel safe around them. Sincere allies also serve as moral exemplars to other members of advantaged groups.

RESUMO

SCIENTIFIC ABSTRACT: We review social-psychological evidence for a theoretically integrative and dynamic model of intergroup conflict escalation within democratic societies. Viewing individuals as social regulators who protect their social embeddedness (e.g., in their group or in society), the intergroup value protection model (IVPM) integrates key insights and concepts from moral and group psychology (e.g., group identification, outrage, moralization, protest) into a functional intergroup value protection process. The model assumes that social regulators are continuously looking for information diagnostic of the outgroup's intentions to terminate the relationship with the ingroup, and that their specific cognitive interpretations of an outgroup's action (i.e., as a violation of ingroup or shared values) trigger this process. The visible value-protective responses of one group can trigger the other group's value-protective responses, thus dynamically increasing chances of conflict escalation. We discuss scientific implications of integrating moral and group psychology and practical challenges for managing intergroup conflict within democratic societies. PUBLIC ABSTRACT: The 2021 Capitol Hill attack exemplifies a major "trigger event" for different groups to protect their values within a democratic society. Which specific perceptions generate such a triggering event, which value-protective responses does it trigger, and do such responses escalate intergroup conflict? We offer the intergroup value protection model to analyze the moral and group psychology of intergroup conflict escalation in democratic societies. It predicts that when group members cognitively interpret another group's actions as violating ingroup or shared values, this triggers the intergroup value protection process (e.g., increased ingroup identification, outrage, moralization, social protest). When such value-protective responses are visible to the outgroup, this can in turn constitute a trigger event for them to protect their values, thus increasing chances of intergroup conflict escalation. We discuss scientific implications and practical challenges for managing intergroup value conflict in democratic societies, including fears of societal breakdown and scope for social change.

RESUMO

Pacific Island Countries (PICs) collectively have the lowest rates of access to safely managed or basic drinking water and sanitation globally. They are also the least urbanised, have dynamic socioeconomic and increasing climate-linked challenges. Community-based water managers need to respond to variability in water availability and quality caused by a range of hazards. Water Safety Planning (WSP), a widely adopted approach to assessing water supply, offers a risk-based approach to mitigating both existing and future hazards. WSP is adaptable, and making modifications to prescribed WSP to adapt it to the local context is common practice. Within the Pacific Community Water Management Plus research project, we used formative research and co-development processes to understand existing local modifications, whether further modifications are required, and, to develop additional modifications to WSP in Fiji, Vanuatu and Solomon Islands. The types of additional local modifications we recommend reflect the unique context of PICs, including adjusting for community management of water supplies and required collective action, community governance systems, levels of social cohesion in communities, and preferred adult-learning pedagogies. Incorporating modifications that address these factors into future WSP will improve the likelihood of sustained and safe community water services in Pacific and similar contexts.

RESUMO

Nonhuman primates and their habitats are facing an impending extinction crisis. Approximately 69% of primate species are listed by the International Union for Conservation of Nature as threatened and 93% have declining populations. Human population growth (expected to reach 10.9 billion by the year 2100), the unsustainable demands of a small number of consumer nations for forest-risk commodities, deforestation and habitat conversion, the expansion of roads and rail networks, cattle ranching, the hunting and trapping of wild primate populations, and the potential spread of infectious diseases are among the primary drivers of primate population decline. Climate change will only exacerbate the current situation. The time to act to protect primate populations is now! In this special issue of the American Journal of Primatology, we present a series of commentaries, formulated as "Action Letters." These are designed to educate and inform primatologists, conservation biologists, wildlife ecologists, political leaders, and global citizens about the conservation challenges faced by particular primate taxa and particular world regions, and present examples of specific actions that one can take, individually and collectively, to promote the persistence of wild primate populations and environmental justice for local human populations and impacted ecological communities. As scientists, researchers, and educators, primatologists are in a unique position to lead local, national, and international efforts to protect biodiversity. In this special issue, we focus on primates of the Brazilian Amazon, lemurs of northeast Madagascar, Temminck's red colobus monkey (Piliocolobus badius temminckii), night monkeys (Aotus spp.), long-tailed macaques (Macaca fascicularis), the primate pet trade, and professional capacity building to foster conservation awareness and action. We encourage primatologists, regardless of their research focus, to engage in both advocacy and activism to protect wild primate populations worldwide.

RESUMO

Despite substantial investments in high-frequency, remote-sensed forest monitoring in the Amazon, early deforestation alerts generated by these systems rarely reach the most directly affected populations in time to deter deforestation. We study a community monitoring program that facilitated transfer of early deforestation alerts from the Global Forest Watch network to indigenous communities in the Peruvian Amazon and trained and incentivized community members to patrol forests in response to those alerts. The program was randomly assigned to 39 of 76 communities. The results from our analysis suggest that the program reduced tree cover loss, but the estimated effects from the experiment are imprecise: We estimate a reduction of 8.4 ha per community in the first year (95% CI [-19.4, 2.6]) and 3.3 ha in the second year (95% CI: [-13.6, 7.0]) of monitoring. The estimated reductions were largest in communities facing the largest threats. Data from monitoring records and community surveys provide evidence about how the program may affect forest outcomes. Community members perceived that the program's monitors were new authorities with influence over forest management and that the monitors' incentivized patrols were substitutes for traditional, unincentivized citizen patrols that suffer from free riding and inhibit timely community detection of and responses to deforestation. Should our findings be replicated elsewhere, they imply that externally facilitated community-based monitoring protocols that combine remote-sensed early deforestation alerts with training and incentives for monitors could contribute to sustainable forest management.

RESUMO

Water scarcity is a global problem that can be compounded by inefficient water management, including underinvestment in infrastructure, underpricing of water use, and underenforcement of user rules. Here, we explore whether these inefficiencies can be reduced in rural Costa Rica via an externally driven community monitoring program (i.e., a program initiated by an outside organization and run by citizens). The monitoring program aimed to reduce groundwater extraction from aquifers, as well as to improve water quality and user satisfaction, by supplying additional information about field conditions and additional scrutiny of user and management authority activities and by fostering citizen engagement in water management. Using a specially designed smartphone application (app) and WhatsApp, monitors could report weekly on the conditions of the water system, including service disruptions, water quality, leaks, and source contamination. The app automatically compiled the individual reports into a summary report, which was then made available to the community water management committees and water users. The program was randomly implemented in 80 of 161 communities that expressed an interest in participating. One year after the program started, we detect modest, albeit imprecisely estimated, effects of the program in the predicted directions: less groundwater extracted, better water quality, and more satisfied users. Although the estimated effects are imprecise, the monitoring program appears to be equally or more cost effective for reducing groundwater extraction than another program in the same region that encouraged households to adopt water-efficient technologies.

RESUMO

BACKGROUND: The COVID-19 pandemic significantly diminished the physical activity (PA) level of Thai adults belonging to Generation Y (Gen Y). As a response to the global crisis, many individuals worldwide have turned to social community platforms, recognizing their potential in promoting PA during the pandemic. Gen Y, in particular, demonstrates exceptional proficiency in using social media platforms, showcasing a remarkable aptitude for swiftly accessing new information and knowledge. However, their proclivity for reckless behavior exposes them to various health risks, potentially leading to enduring adverse health consequences. Consequently, there arises a pressing need to develop a comprehensive model aimed at elevating the PA levels among individuals belonging to Gen Y. OBJECTIVE: This research aimed to examine the effectiveness of a digital group-based activity in promoting PA among Gen Y in Thailand. METHODS: This was a parallel 2-arm randomized controlled trial with single-blind allocation to experimental and control groups and pre- and posttest measurements. Measurements were administered on the web and were designed for respondents to complete by themselves. The sample comprised 100 Gen Y individuals who met the inclusion criteria. Both groups were matched for background characteristics. The two 8-week intervention activities were (1) two weeks of education and (2) six weeks of motivation by target groups that set goals for PA together (using the Zoom meeting application), with a time limit and group consensus as to when the goal was to be achieved. The intervention activities were implemented one by one at specified intervals and delivered daily through health apps and the official LINE account. RESULTS: The intervention starts from August 22 to October 16, 2021. Of the 100 participants, 20 (20%) left the study, and the remaining 80 (80%) participated in the study (40 individuals each in the experimental and control groups). After participating in the experiment, a statistically significant difference in PA was found between the 2 groups (moderate to vigorous PA; 25/40, 63%; P=.03). Participants in the intervention group collected a higher cumulative minute of moderate to vigorous PA weekly (283 minutes) than those in the control group (164 minutes), and this was statistically significant (P=.03). For the transition to the fourth stage of behavior (ie, action), the improvement in the experimental group, after participating in the trial, was statistically significant compared to that of the control group (P=.01). CONCLUSIONS: Digital group-based activity showed its effectiveness in improving the PA of Gen Y individuals in the intervention group. It created a process-based intervention activity that corresponds to the stages of behavior changes, from contemplation to action. The digital community can also connect individuals to comparable groups locally and globally.

RESUMO

The policy actions of countries reflect adaptive responses of local components within the system to the dynamic global risk landscape. These responses can generate interactions and synergy effects on alleviating the evolution of global risks. Adopting a network perspective, the study proposes a theoretical framework that connects three structural characteristics of policy synergy, namely, synergy scale, alignment intensity, and timing synchronization. Focusing on the Covid-19 pandemic as a typical global risk context, the study finds that policy synergy with a larger scale, stronger alignment intensity, and more synchronized timing has a positive impact on mitigating global risks. The effect of alignment intensity is particularly pronounced when polycentric governance involves 20 countries facing severe risks, whereas the effect of timing synchronization is more significant when the multicenter group comprises more countries. Building upon the concept of an efficient scale of polycentric governance in various dimensions, this study develops a policy synergy index model. Through multiple empirical analyses, this study validates the causal relationship between policy synergy and the future evolution of global pandemic risk. Policymakers can leverage the dynamic changes in the policy synergy to predict future risk situations and implement well-rounded and appropriate policy actions, thereby enhancing the efficacy of the synergy effect of multi-country policy actions for risk governance.

RESUMO

We present findings from the Our Voice in Barú project, examining adolescent engagement in citizen science to address environmental and social factors affecting well-being in a semi-rural Afro-descendant community in Latin America. The project aimed to identify barriers and enablers of well-being, informing adolescent-led actions for sustainable environmental changes relevant to adolescent health. Utilizing the Our Voice citizen science method, which involved technology-enabled walks, participatory cartography workshops and community meetings, we engaged adolescents and other community members. Complex systems framework was employed to analyze results and assess the promotion of collective action and local change. Local enablers of well-being included availability of quality sports and recreational venues as safe spaces, educational settings and cultural aspects, fostering safety, community pride, and personal growth. Conversely, barriers included environmental contamination, deteriorated sports venues and drug addiction, indicating the community's limited access to services and exposure to harmful substances. Adolescent citizen scientists, in partnership with the research team and relevant community decision-makers, successfully achieved changes aimed at identified barriers, including infrastructural enhancements like the repair of pumps to remove stagnant water, improvements in the quality and safety of recreational venues, and the implementation of community-led initiatives to address substance abuse and promote healthier behaviors. The Our Voice in Barú project empowered adolescents to advocate for change and promoted collective action to tackle barriers identified as significant to their well-being.

RESUMO

Lynching remains a common form of collective punishment for alleged wrongdoers in Latin America, Africa, and Asia today. Unlike other kinds of collective violence, lynching is usually not carried out by standing organizations. How do lynch mobs overcome the high barriers to violent collective action? I argue that they draw on local community ties to compensate for a lack of centralized organization. Lynch mobs benefit from solidarity and peer pressure, which facilitate collective action. The study focuses on Mexico, where lynching is prevalent and often amounts to the collective beating of thieves. Based on original survey data from Mexico City and a novel lynching event dataset covering the whole of Mexico, I find that individuals with more ties in their communities participate more often in lynching, and municipalities with more highly integrated communities have higher lynching rates. As community ties and lynching may be endogenously related, I also examine the posited mechanisms and the causal direction. Findings reveal that municipalities exposed to a recent major earthquake-an event that tends to increase community ties-subsequently experienced increased levels of lynching. Importantly, I find that interpersonal trust is unrelated to lynching, thus showing that different aspects of social capital have diverging consequences for collective violence, with community ties revealing a "dark side."

RESUMO

Renewable portfolio standards (RPS) and tradable green certificate (TGC) systems are mandatory institutional change that promote the renewable energy development and improve the environment in China. Their implementation will cause collective action issues among market entities. Collective action of participating in TGC trading is crucial for transaction success and the effectiveness of system implementation. This paper takes the collective action of heterogeneous market entities participating in TGC trading as the starting point. This paper simulates the strategy selection and group behavior evolution of different market entities under multiple scenarios, and analyzes collective action's evolutionary path and equilibrium results under different group combination environments. It explores the success rate of TGC trading under different heterogeneous entities combinations through an evolutionary game model, revealing the reasons for low liquidity of China's TGC market. The results show that: (1) Heterogeneity is an important factor affecting the success of TGC collective action. (2) When TGC suppliers and demanders are egoists, collective actions appear in multiple equilibria. As egoists decrease, the probability of market entities participating in collective actions increases, and TGC transactions are more successful. (3) Altruists can shorten the time for collective action to achieve equilibrium and reduce the possibility of multiple equilibria. (4) TGC suppliers play a greater guiding role in the transaction. When TGC suppliers are altruists, the probability of TGC demanders participating in collective action tends to 1. Conversely, TGC transaction success rate is 50%.

RESUMO

Given the multiple challenges that agriculture faces, collective action is a potential pathway towards more sustainable agriculture. This article aims to contribute to the literature by assessing the extent to which collective action can meet the objective of both healthy and profitable production in the French West Indies. To do so, we call on the theory of collective action and emphasise the role of formal and informal collectives in achieving the objectives of improving income and implementing agroecological practices. We use original data collected in 2022 from 409 vegetable farmers in Martinique and Guadeloupe. We consider the interdependence between farmers' economic and environmental objectives through a simultaneous equations model. We characterise the diversity of collectives according to their degree of formalisation and to the adequacy between the objectives pursued by these collectives and the individual objectives of their members. Our results show that the achievement of an individual objective is fostered by its adequacy with the objective set by the collective and also, to a certain extent, by the degree of formalisation of this collective. It appears that achieving individual objectives is based on sharing common objectives as well as having collective rules. More particularly, we find that producer organisations - collectives considered to be the most formal - best meet the objectives of improving income and adopting agroecological practices. However, in the French West Indies, the instability of such collectives and the organisational deficiencies of the sector call into question their real long-term impact. These findings contribute to a better understanding of farmers' decision-making and provide relevant policy implications for supporting agricultural collectives in managing and federating producers towards achieving a more healthy and profitable production.

RESUMO

Landscape governance challenges, particularly in peri-urban contexts like the Bannerghatta National Park (BNP) region in South India, exemplify 'wicked' problems due to their inherent complexities. These challenges arise from a mix of conflicting interests, policy ambiguities, and sociocultural dynamics, which often blur the definition of problems and hinder effective solutions. Despite apparent options for resolution, stakeholder disagreements and deep uncertainties about implementation strategies complicate governance. This study, therefore, has two broad objectives. The first objective is to analyze the local discourses surrounding planned policy interventions around the BNP region in South India. Based on the findings, the second objective is to draw insights for sustainable natural resource governance research and practice. We applied Q-methodology to understand the discourses that underpin various conflicts in the rapidly urbanizing elephant corridor at BNP. We elicited information on how various local actors frame solutions to current collective action challenges in the BNP landscape and their perspectives on the proposed eco-sensitive zone notification, as well as the functioning of current policy interventions concerning conservation and development. The study uncovers the micropolitics and power regimes underpinning various natural resource governance challenges and demonstrates the utility of the Q-methodology in bringing diverse perspectives together in response to 'wicked' governance challenges.
