Traded Plastic, Traded Impacts? Designing Counterfactual Scenarios to Assess Environmental Impacts of Global Plastic Waste Trade.

The global trade of plastic waste has raised environmental concerns, especially regarding pollution in waste-importing countries. However, the overall environmental contribution remains unclear due to uncertain treatment shares between handling plastic waste abroad and domestically. Here, we conduct a life cycle assessment of global plastic waste trade in 2022 across 18 countries and six plastic waste types, alongside three "nontrade" counterfactual scenarios. By considering the required cycling rate, which balances importers' costs and recycling revenues, we find that the trade resulted in lower environmental impacts than treating domestically with the average treatment mix. The trade scenario alone reduced climate change impact by 2.85 million tonnes of CO2 equivalent and mitigated damages to ecosystem quality, human health, and resource availability by 12 species-years, 6200 disability-adjusted life years (DALYs), and 1.4 billion United States dollars (USD in 2013), respectively. These results underscore the significance of recognizing plastic waste trade as a pivotal factor in regulating global secondary plastic production when formulating a global plastics treaty.

Reflective questioning to guide socially just global health reform: a narrative review and expert elicitation.

Recent research has highlighted the impacts of colonialism and racism in global health, yet few studies have presented concrete steps toward addressing the problems. We conducted a narrative review to identify published evidence that documented guiding frameworks for enhancing equity and inclusion in global health research and practice (GHRP). Based on this narrative review, we developed a questionnaire with a series of reflection questions related on commonly reported challenges related to diversity, inclusion, equity, and power imbalances. To reach consensus on a set of priority questions relevant to each theme, the questionnaire was sent to a sample of 18 global health experts virtually and two rounds of iterations were conducted. Results identified eight thematic areas and 19 reflective questions that can assist global health researchers and practitioners striving to implement socially just global health reforms. Key elements identified for improving GHRP include: (1) aiming to understand the historical context and power dynamics within the areas touched by the program; (2) promoting and mobilizing local stakeholders and leadership and ensuring measures for their participation in decision-making; (3) ensuring that knowledge products are co-produced and more equitably accessible; (4) establishing a more holistic feedback and accountability system to understand needed reforms based on local perspectives; and (5) applying systems thinking to addressing challenges and encouraging approaches that can be sustained long-term. GHRP professionals should reflect more deeply on how their goals align with those of their in-country collaborators. The consistent application of reflective processes has the potential to shift GHRP towards increased equity.

"There's a little bit of mistrust": Red River Métis experiences of the H1N1 and COVID-19 pandemics.

We examined the perspectives of the Red River Métis citizens in Manitoba, Canada, during the H1N1 and COVID-19 pandemics and how they interpreted the communication of government/health authorities' risk management decisions. For Indigenous populations, pandemic response strategies play out within the context of ongoing colonial relationships with government institutions characterized by significant distrust. A crucial difference between the two pandemics was that the Métis in Manitoba were prioritized for early vaccine access during H1N1 but not for COVID-19. Data collection involved 17 focus groups with Métis citizens following the H1N1 outbreak and 17 focus groups during the COVID-19 pandemic. Métis prioritization during H1N1 was met with some apprehension and fear that Indigenous Peoples were vaccine-safety test subjects before population-wide distribution occurred. By contrast, as one of Canada's three recognized Indigenous nations, the non-prioritization of the Métis during COVID-19 was viewed as an egregious sign of disrespect and indifference. Our research demonstrates that both reactions were situated within claims that the government does not care about the Métis, referencing past and ongoing colonial motivations. Government and health institutions must anticipate this overarching colonial context when making and communicating risk management decisions with Indigenous Peoples. In this vein, government authorities must work toward a praxis of decolonization in these relationships, including, for example, working in partnership with Indigenous nations to engage in collaborative risk mitigation and communication that meets the unique needs of Indigenous populations and limits the potential for less benign-though understandable-interpretations.

The biological standard of living of Korean men under Confucianism, colonialism, capitalism, and communism.

This study focuses on analysing the heights of 10,953 Korean men aged 20 to 40 years who were measured during the Joseon dynasty, the Japanese colonialisation period, and the contemporary period, the latter including both North and South Korea. This study thus provides rare long-term statistical evidence on how biological living standards have developed over several centuries, encompassing Confucianism, colonialism, capitalism, and communism. Using error bar analysis of heights for each historical sample period, this study confirms that heights rose as economic performance improved. For instance, economically poorer North Koreans were expectedly shorter, by about 6 cm, than their peers living in the developed South. Similarly, premodern inhabitants of present-day South Korea, who produced a gross domestic product (GDP) per capita below the world average, were about 4 cm shorter than contemporary South Koreans, who have a mean income above the world average. Along similar lines, North Koreans, who have a GDP per capita akin to that of the premodern Joseon dynasty, have not improved much in height. On the contrary, mean heights of North Koreans were even slightly below (by about 2.4 cm) heights of Joseon dynasty Koreans. All in all, the heights follow a U-shaped pattern across time, wherein heights were lowest during the colonial era. Heights bounced back to Joseon dynasty levels during the interwar period, a time period where South Korea benefitted from international aid, only to rise again and surpass even premodern levels under South Korea's flourishing market economy.

Recovering the status quo: tipping points and earthquake aftermaths in colonial India.

Scholars of disaster politics debate how far natural hazards cause or catalyse political change. This paper builds on recent scholarship on tipping points and social contracts to argue that two case studies of historical earthquakes in 1930s British-colonised India invite a focus on the dynamics of cooperation and conflict between state and non-state actors. Officials of the colonial state and its nationalist rivals cooperated after one earthquake even though they otherwise bitterly opposed each other. Cooperation broke down after the second event, just one year later. Yet, in both cases, officials and nationalist leaders shared a broad vision for Indian society, which pushed both sides actively to seek to recover the social and economic status quo ante, preventing potential tipping points from crystallising. These case studies reveal how and why highly fraught social contracts can survive major disasters. The colonial state's transient and reactive approach to disaster governance continued to impact on post-independence India.

Mental models for inclusive, socially-just disaster planning: a multi-community study in Saint Martin after Hurricane Irma.

Local perspectives provide different insights into disaster planning and response as compared to those of experts. Eliciting them, however, can be challenging, particularly for marginalised groups whose viewpoints have historically been excluded from planning processes. Fuzzy cognitive mapping (FCM) provides a semi-quantitative approach to representing the collective understanding or 'mental models' of diverse individuals and communities. This study involved 23 FCM interviews across three neighbourhoods of Saint Martin to comprehend: (i) how individuals' mental models of Hurricane Irma (2017) differ based on their context; (ii) how aligned mental models are with policy and planning documents; and (iii) the implications for the inclusiveness and representativeness of disaster response policies. It found that the residents of different neighbourhoods provided unique insights into the factors driving the social-ecological system, and that official policies aligned closely with priorities. The paper argues that the inclusion of the perspectives of different groups in disaster recovery is essential for an equitable process.

Imperial algorithms: Contemporary manifestations of racism and colonialism.

In this special issue, we invited contributions that critically examined issues of imperialism, colonialism, power, justice, etc. to expand the canon of anticolonial scholarship and critical scholarship in community psychology. Our two objectives were: (1) to build on the canon of anticolonial and critical race scholarship to cultivate an empirical and theoretical body of work and conceptual frameworks about racism and colonialism within the field of community psychology and (2) to unpack the different manifestations of racism in society from the lens of community psychology and reflect on the implications of these varied forms of injustice in the contemporary moment. Rooted in African epistemology and methodology (Martin, 2012), we find the concept of the algorithm to serve as a potent metaphor for the ways in which these oppressive structures operate given the prevalence of algorithms in our daily lives and the algorithm is symbolic of the information age and predictive powers that seem to govern society beyond conscious control. In this sense, imperial algorithms are these structures, patterns, processes, and procedures that perpetuate imperialism. These imperial algorithms manifest as neo-colonialism, surveillance, social engineering, carcerality, reality warping of contemporary racism, health disparities exacerbated by COVID-19, and environmental grids of oppression.

Reducing Indigenous suicide: Recognizing vital land and food systems for livelihoods.

Colonial trauma poses a significant risk to the physical, intellectual, and mental health of Indigenous youth and young adults. Education and mental health scholars are increasingly concerned about the emotional wellbeing of young people, particularly as rates of suicide have increased across the United States. With interest in identifying the unique contextual dynamics involved in understanding Indigenous suicide, this work considers characteristics related to colonialism that may uncover strategies for both educators and mental health practitioners that address disparities. Drawing on a larger ethnographic study, this inquiry asks how settler encroachment upon Indigenous land and food systems is related to death by suicide from the perspective of Cowichan Tribes members. Comprehensive semi-structured interviews were conducted (n = 21); each interview was audio-recorded and transcribed verbatim. Data were analyzed deductively based upon a priori suppositions related to settler colonial theory. Cowichan members' narrated explanations for suicide rooted in disruptions to (1) relationships with the land and (2) traditional food systems. They described how settler encroachment infringed upon their subsistence way of living and introduced incongruent constructions of nature-culture relations (e.g., humans as distinct and separate from the natural world). Settler futurity is secured through the arrogation of territorial dominance coupled with physical or conceptual acts of erasure, placing Indigenous lives and lifeways at risk. One outcome of the disruption to Indigenous collective capacities is a dramatic increase in Indigenous suicide.

Marginalization and women's healthcare in Ghana: Incorporating colonial origins, unveiling women's knowledge, and empowering voices.

The origins of marginalization in nursing and the health sector in Ghana can be traced to colonialism and how a colonial era laid a solid foundation for inequities and entrenched disparities, as well as the subsequent normalization of marginalizing acts, in the health sector, particularly for women. Drawing upon varied literature over a 60-year period and perspectives from feminist theory, this paper considers the lasting impact of Ghanaian women's historical position during the colonial era and within the patriarchal system that ensued. Through this process, it becomes possible to shed light on the crucial role that colonialism has played in women's experiences, perspectives, and health-seeking behaviors, and the manner in which it has created a healthcare sector that marginalizes women's health. Although women possess valuable knowledge which should be an asset to consider when providing healthcare services, marginalization of that knowledge has become normalized across society and the healthcare system. There is an urgent need to disrupt and challenge this normalization, and to advocate empowerment and recognition of women's valuable knowledge and experiences, providing women a voice in health decision-making discourses and in the research processes by which we understand and develop healthcare. Through this, healthcare in Ghana could become more empowering, inclusive, and responsive to the unique experiences and needs of Ghanaian women. By understanding something of the historical origins of women's health marginalization within colonialism, nurses can begin to appreciate women's knowledge and integrate it into healthcare strategies that are more gender-sensitive and equitable.

The Figure of the Staggering Rat: Reading Colonial Outbreak Narratives Against the Grain of "Virus Hunting".

The image of dazed, plague-infected rats coming out of their nests and performing a pirouette in front of the surprised eyes of humans before dying is one well-known to us through Albert Camus's The Plague (1947). This article examines the historical roots of this image and its emergence in French missionary narratives about plague outbreaks in the Chinese province of Yunnan in the 1870s on the eve of the Third Plague Pandemic. Showing that accounts of the "staggering rat" were not meant as naturalist observations of a zoonotic disease, as is generally assumed by historians, but as a cosmological, end-of-the-world narrative with a colonial agenda, the article argues for an approach to historical accounts of epidemics that does not succumb to the current trend of "virus hunting" in the archive, but rather takes colonial outbreak narratives ethnographically seriously.

Violence, Misrecognition, and Place: Legal Envelopment and Colonial Governmentality in the Upper Skeena River, British Columbia, 1888.

This paper is concerned with exploring legal atmospheres during colonial expansionism and the early period of confederation of British Columbia. By describing the theatrical and performative aspects of legal colonialism, the archival documents from this time represent interesting, yet oft-overlooked, significances that attention to sensory and affective experiences captures. Examining "affective atmospheres" disclosed in such colonial settings reveals ways that the colonial regime promulgated its influence in non-rational, non-legal manners. As well, drawing out the material conditions of topography shows how the environment acts more than just a backdrop for the staging of legal expansionism, as it acts also as a constitutive force in the development of colonial legal arrangements. At the same time, the colonial regime was forgetful of these same contextual, topographical, and atmospheric origins of law insofar as it promulgated myths of the universality, objectivity, and superiority of English law.

Neo-Traditional and Industrialized Dietary Patterns Coexist and Are Differentially Associated with Cardiometabolic Health among Adults in Puerto Rico.

BACKGROUND: An increasingly industrialized food system has marginalized local, traditional food cultures in Puerto Rico (PR). Recent efforts to decolonize diets have promoted local food intake; however, how resulting dietary patterns may influence cardiometabolic disease remains unknown. OBJECTIVES: This study aimed to 1) identify dietary patterns in PR and 2) determine their associations with metabolic syndrome (MetS) and its components. METHODS: Data were obtained from participants (30-75 y) in PROSPECT (PR Observational Study of Psychosocial, Environmental, and Chronic Disease Trends; n = 989). Dietary patterns were derived using partial least squares analysis with food frequency questionnaire data, using nutrients associated with local food purchasing (dietary fiber, magnesium, saturated fat) as response variables. MetS was classified using harmonized criteria from clinical and laboratory measures and medication use. Fully adjusted generalized linear models tested associations between tertiles of dietary patterns and MetS. RESULTS: Approximately half (52%) of the participants were classified with MetS. Four dietary patterns were revealed: conventional (legumes, coffee, and dairy), industrialized starch and meat-centric (red/processed meats, pasta, and starchy roots), industrialized sugar-centric (rice, sugary beverages, and refined grains), and neo-traditional (local plants and seafood). Individuals in the highest (compared with lowest) tertile of the industrialized starch and meat-centric dietary pattern had higher mean waist circumference (102 compared with 99 cm) (P = 0.01), fasting glucose (106 compared with 98 mg/dL) (P = 0.019), and systolic blood pressure (123 compared with 119 mmHg) (P = 0.022). Individuals in the highest (compared with lowest) tertile of the neo-traditional diet were 0.69 (0.49, 0.97) times less likely to have MetS (P = 0.035) and had 4.1 cm lower mean waist circumference (P = 0.002). CONCLUSIONS: Promoting a neo-traditional diet and curbing industrialized starch and meat-centric diets may improve cardiometabolic health in PR. Results can guide local food promotion as a healthful, decolonizing approach in island settings.

Moving beyond ontological (worldview) supremacy: Indigenous insights and a recovery guide for settler-colonial scientists.

Greater engagement and representation of Indigenous voices, knowledges and worldviews in the biological sciences is growing globally through efforts to bring more Indigenous academics into scientific research and teaching institutions. Although the intentions of such efforts may be admirable, these spaces often become sites of great personal tension for the Indigenous scholars who must 'bridge' or 'facilitate' a dialogue between Indigenous and settler-colonial (predominantly Western) knowledge traditions and worldviews. We are a small collective of early career Indigenous scholars from Australia, the United States and Aotearoa New Zealand, and we have gained insights into this situation through the unique experiential learning afforded by navigating such tensions. Here, we discuss tensions that bear remarkable similarities across geographies, cultures and settler-colonial contexts. In doing so, we aim to support other Indigenous scientists and scholars navigating settler-colonial and Western research institutions, while offering guidance, suggestions and reflections for the scientific community to allow the development of more nuanced strategies to support Indigenous academics than simply increasing Indigenous representation. We imagine transformed, innovative research and teaching agendas where Indigenous knowledges can thrive, and Indigenous scientists can apply themselves with mutual and balanced respect and reciprocity.

The history of natural history and race: Decolonizing human dimensions of ecology.

Natural history, loosely defined as the observational study of organisms in the habitats where they occur, is recognized at the roots of ecology. Although the centrality of natural history in ecology has shifted over time, natural history is currently in resurgence: many again consider it to be the foundation of ecological and evolutionary inquiry and advocate the value of organism-centered approaches to address contemporary ecological challenges. Educators identify natural history as the foundational entryway into the practice of ecology, for example in the Ecological Society of America's Four-Dimensional Ecology Education (4DEE) framework. A strong natural history foundation can help generate testable hypotheses to refine mechanistic understanding of the drivers regulating species distributions and abundances and to inform restoration and conservation efforts. Given the resurgence of natural history as the foundation for ecological knowledge and practice, it is important to recognize that natural history has a long history of racism that has impacted ecological thought and priorities. This history shapes not only who conducts ecological science but also foundational ecological concepts. For example, natural history's emphasis on pristine nature untouched by humans disregards or appropriates stewardship and knowledge of most of the world's population. Because of the legacy of chattel slavery, this exclusion is particularly strong for people of African descent. This exclusion narrows ecological inquiry, limits the capacity to find solutions to ecological problems, and risks interventions that perpetuate the relation between eugenics, ecological knowledge, and natural systems. If ecology is to become an inclusive, responsive, and resilient discipline, this knowledge gap must be addressed. We here present the colonial and racist underpinnings of natural history and offer strategies to expand inclusion in the study of nature. Natural history was steeped in racism, providing a hierarchy of cultures and a taxonomy of races. Complementing growing interest in traditional and Indigenous ecological knowledge, we focus on Black ecological knowledge, for example in the study of "maroon ecologies." Addressing the racist history of natural history is necessary for removing structural and racist barriers to diverse participation and expanding ecological knowledge bases in service of better and more just science.

Five ways 'health scholars' are complicit in upholding health inequities, and how to stop.

Health scholars have been enthusiastic in critique of health inequities, but comparatively silent on the ways in which our own institutions, and our actions within them, recreate and retrench systems of oppression. The behaviour of health scholars within academic institutions have far reaching influences on the health-related workforce, the nature of evidence, and the policy solutions within our collective imaginations. Progress on health equity requires moving beyond platitudes like 'equity, diversity and inclusion' statements and trainings towards actually being and doing differently within our day-to-day practices. Applying complex systems change theory to identify, examine and shift mental models, or habits of thought (and action), that are keeping us stuck in our efforts to advance health equity is a promising approach. This paper introduces five common mental models that are preventing meaningful equity-oriented systems transformation within academia and offers ideas for shifting them towards progressively more productive, and authentic, actions by health scholars to advance health equity across systems.

Psychology and Indigenous People.

Whether there are common features inherent to the psychology of Indigenous peoples around the globe has been the subject of much debate. We argue that Indigenous peoples share the experience of colonization and its social and psychological consequences. We develop this argument across four sections: (a) the global history of colonization and social inequalities; (b) aspects concerning identity and group processes, including the intergenerational transmission of shared values, the connection with nature, and the promotion of social change; (c) prejudice and discrimination toward Indigenous peoples and the role of psychological processes to improve relations between Indigenous and non-Indigenous peoples; and (d) the impact of historical trauma and colonialism on dimensions including cognition, mental health, and the well-being of Indigenous peoples as well as the basis for successful interventions that integrate Indigenous knowledge. Finally, we address future challenges for research on these topics.

Situating commercial determinants of health in their historical context: a qualitative study of sugar-sweetened beverages in Jamaica.

BACKGROUND: Non-communicable diseases (NCDs) are the leading cause of mortality across the Caribbean and similar regions. Structural determinants include a marked increase in the dependency on food imports, and the proliferation of processed foods, including sugar-sweetened beverages (SSBs). We focused on Jamaica as a case study and the health challenge of SSBs, and situated contemporary actions, experiences and policies within their historical context to investigate underlying drivers of commercial determinants of health and attempts to counter them. We asked: how can a historical perspective of the drivers of high level SSB consumption in Jamaica contribute to an enhanced understanding of the context of public health policies aimed at reducing their intake? METHODS: An ethnographic approach with remote data collection included online semi-structured interviews and workshops with 22 local experts and practitioners of health, agriculture and nutrition in Jamaica and attending relevant regional public webinars on SSBs and NCD action in the Caribbean. Our analysis was situated within a review of historical studies of Caribbean food economies with focus on the twentieth century. Jamaican and UK-based researchers collected and ethnographically analysed the data, and discussed findings with the wider transdisciplinary team. RESULTS: We emphasise three key areas in which historical events have shaped contextual factors of SSB consumption. Trade privileged sugar as a cash crop over food production during Jamaica's long colonial history, and trade deregulation since the 1980s through structural adjustment opened markets to transnational companies. These changes increased Jamaican receptiveness to the mass advertisement and marketing of these companies, whilst long-standing power imbalances hampered taxation and regulation in contemporary public health actions. Civil society efforts were important for promoting structural changes to curb overconsumption of SSBs and decentring such entrenched power relations. CONCLUSION: The contemporary challenge of SSBs in Jamaica is a poignant case study of commercial determinants of health and the important context of global market-driven economies and the involvement of private sector interests in public health policies and governance. Historically contextualising these determinants is paramount to making sense of the sugar ecology in Jamaica today and can help elucidate entrenched power dynamics and their key actors.

The Language of Research: Creating Spaces to Better Understand How We Speak and How We Are Heard.

Anti-Indigenous racism education and cultural safety training can help cultivate greater awareness and hold the potential to encourage Western-trained researchers to work in solidarity with Indigenous partners to resist the structural status quo. The purpose of this article is to provide an overview and author reflections on an immersive educational series "The Language of Research: How Do We Speak? How Are We Heard?". The series was developed by a Canadian group that included an Indigenous Knowledge Keeper, non-Indigenous researchers, and parent partners, all of whom have training or experience in Westernized research and/or health care. The 6-session virtual series was made available through a provincial pediatric neurodevelopment and rehabilitation research group in Canada. Participation was open to a broad audience, including but not limited to researchers, clinicians, families, and health-care professionals. This learning opportunity was developed as a starting point for ongoing integration of an anti-racism perspective within our provincial research group and began through conversation about how words or language typically used in Western approaches to research, ("recruit," "consent," "participant") could be unwelcoming, exclusionary, and harmful. Topics that were explored during the sessions included Using Descriptive Language/Communication; Relationships and Connection; and, Trust, Healing, and Allyship. The article aims to contribute to the ongoing dialogue related to disrupting racism and decolonizing research in the fields of neurodevelopment and rehabilitation. Reflections about the series are offered by the authorship team throughout the article, to solidify and share learning. We acknowledge this is only one of many steps in our learning.

Conceptualising mental illness among University students of African, Caribbean and similar ethnic heritage in the United Kingdom.

OBJECTIVE: Students of African, Caribbean and similar ethnicity (ACE) encounter unique mental health challenges within the Western higher education system, such as feeling constrained in social spaces and perceiving greater stigma about mental health. Students of ACE are also resilient to mental health problems, such as depression, when enduring social inequality. This study aimed to conceptualise mental illness and help-seeking behaviours among university students in the United Kingdom (UK) in the context of their identity as ACE. DESIGN: Six university students of ACE in the UK were interviewed about the meaning of mental illness, the influence of ACE culture on mental health and help-seeking by ACE students. Thematic analysis was applied from a socio-constructionist theoretical lens to interpret the interview transcripts. RESULTS: Five main themes emerged, namely 'Perceived meanings and attitudes toward mental health problems', 'Beliefs about the non-existence of mental health problem and its spiritual attributions', 'Family dynamics and the 'silencing' of mental health problems', 'Help-seeking for mental health among people of ACE' and 'Stigma and discriminatory responses to mental health issues'. Participants expressed that mental health is an imported concept that people from ACE communities tend to shy away from. A reluctance to discuss mental health problems arose over fear of rejection from families and fear of not being understood by a mental health professional from a different cultural background. CONCLUSION: University students of ACE and their families struggle to adopt the Western conceptualisation of mental health. Consequently, there is poor awareness of mental health issues and stigma of mental illness among university students of ACE which pose a barrier to help-seeking for mental health. The limited sample size constrains the ability to draw sound conclusions. Nonetheless, a culturally sensitive conceptualisation of mental health is needed to address poor help-seeking for mental health among people of ACE.

Indigenous men's pathways to 'living the right kind of life and walking the right path' post incarceration in Canada: understanding the impacts of systemic oppression, and guidance for healing and (w)holistic sexual health.

Indigenous men around the world hold expertise over their own lives. Informed by this perspective, this study centres this experience to better understand what is needed to improve sexual health outcomes among a group of men with a history of incarceration. Semi-structured interviews were conducted with 10 Indigenous men with such a history. Through thematic analysis the study identified two major themes: 1) the impacts of systemic oppression; 2) the value of guidance in walking the right path. Men identified colonial trauma and the associated mental, physical, emotional and spiritual wounds stemming from systemic oppression as continuing to impact their wellbeing. Men also described the systems of support necessary to help guide them on their journeys through incarceration, rehabilitation and building strong and nurturing relationships. Findings from the study provide important guidance from Indigenous men for future more holistic sexual health intervention programming.
