The Andean zinc rush: Green extractivism and climate vulnerabilities in the Peruvian highland waterscapes

Zinc is a green mineral that is increasingly required for manufacturing low-carbon technology. This demand has been promoted mainly by the Global North-led green policies to mitigate the impacts of climate change. However, simultaneously expanding zinc mining risks further entrenching climate threats in fragile socio-ecological environments such as the Peruvian highlands. This article analyses the linkages between the accelerated green extractivism of zinc and its associated climate-related vulnerabilities in the Cunas watershed in the Central highlands of Peru. The study draws on ethnographic-oriented fieldwork in the area in 2019, and 2022 and a review of policy documents on climate mitigation and zinc mining in Peru. The analysis particularly focuses on the recently reopened Azulcocha zinc mine and its intertwined socio-ecological effects on the local waterscapes amid climate change. The analysis draws the theoretical approaches of the political ecology of green extractivism and vulnerability to disentangle the multi-scalar power dynamics embedded in the global low-carbon transition and green extractivism and how these shape climate-related vulnerabilities. The study shows that with the impacts of climate change, accelerated extractivism risks (re)producing multiple vulnerabilities in the Andean highland communities. The findings highlight the urgent need to rethink the global climate proposals in such a way that they do not deepen climate damage in the already marginalized waterscapes in the Andes and elsewhere in the Global South.

Perspectives on the insidious nature of pain metaphor: we literally need to change our metaphors.

Metaphorical language is used to convey one thing as representative or symbolic of something else. Metaphor is used in figurative language but is much more than a means of delivering "poetic imagination". A metaphor is a conceptual tool for categorising, organizing, thinking about, and ultimately shaping reality. Thus, metaphor underpins the way humans think. Our viewpoint is that metaphorical thought and communication contribute to "painogenicity", the tendency of socio-ecological environments (settings) to promote the persistence of pain. In this perspectives article, we explore the insidious nature of metaphor used in pain language and conceptual models of pain. We explain how metaphor shapes mental organisation to govern the way humans perceive, navigate and gain insight into the nature of the world, i.e., creating experience. We explain how people use metaphors to "project" their private sensations, feelings, and thoughts onto objects and events in the external world. This helps people to understand their pain and promotes sharing of pain experience with others, including health care professionals. We explore the insidious nature of "warmongering" and damage-based metaphors in daily parlance and demonstrate how this is detrimental to health and wellbeing. We explore how metaphors shape the development and communication of complex, abstract ideas, theories, and models and how scientific understanding of pain is metaphorical in nature. We argue that overly simplistic neuro-mechanistic metaphors of pain contribute to fallacies and misnomers and an unhealthy focus on biomedical research, in the hope of developing medical interventions that "prevent pain transmission [sic]". We advocate reconfiguring pain language towards constructive metaphors that foster a salutogenic view of pain, focusing on health and well-being. We advocate reconfiguring metaphors to align with contemporary pain science, to encourage acceptance of non-medicalised strategies to aid health and well-being. We explore the role of enactive metaphors to facilitate reconfiguration. We conclude that being cognisant of the pervasive nature of metaphors will assist progress toward a more coherent conceptual understanding of pain and the use of healthier pain language. We hope our article catalyses debate and reflection.

Social Mobility and Motivational Payoff: Achievement Motivation Is More Important in Students’ Performance and Well-Being in Cultures With High Versus Low Social Mobility

Achievement motivation encompasses a well-establish distinction between the motive to avoid failure (e.g., fear of failure) and the orientation to improve competence (e.g., mastery goal). But how well do they generalize across cultures in understanding students’ performance and well-being? We argue that students’ achievement motivation is less pronounced in societies characterized by low (vs. high) social mobility, where people have fewer opportunities to change their social status. To test this hypothesis, we analyzed a cross-national data set ( n = 498,362 high-school students from 65 regions) using multilevel modeling. The results indicated that societal-level social mobility significantly moderated the role of (a) mastery goals and fear of failure on academic performance and (b) fear of failure on well-being. These associations were stronger in societies with high (vs. low) social mobility, suggesting that students derive greater academic benefits from mastery goals and fear of failure in societies with higher social mobility. In such societies, however, fear of failure also poses a stronger hindrance to students’ well-being. These findings highlight that the same type of motivation may operate differently across cultures and that socioecological environments may influence the motivational impacts on learning and well-being.

"Where Creator Has My Feet, There I Will Be Responsible": Place-Making in Urban Environments through Indigenous Food Sovereignty Initiatives.

There is a growing emergence of Indigenous Food Sovereignty (IFS) initiatives across urban centers within many regions of Canada. Urban Indigenous communities are leading these efforts to revitalize Indigenous foods and agricultural practices while promoting food security and increasing Land-based connections within cities. However, the socio-ecological environments within these urban contexts affect IFS initiatives in unique ways which have not been previously explored. This study addresses these gaps by drawing on qualitative interviews with seven urban Indigenous people leading IFS initiatives within Grand River Territory (situated within southern Ontario, Canada). Applying community-based participatory methods, this research explored how place impacts IFS initiatives within urban environments. Thematic analysis generated two overarching thematic categories: Land access, and place-making practices, revealing a bi-directional, dynamic interaction between place and urban IFS initiatives. Relationships with landowners, control of land, and external factors determined how Land was accessed in urban environments. Place-making practices involved fostering relationships with Land, upholding responsibilities, and cultivating Land-based knowledges. Therefore, IFS initiatives are impacted by Land access, but also facilitate place-making for urban Indigenous Peoples. These findings demonstrate pathways towards Indigenous self-determination and IFS within urban contexts, which can be applicable to other urban Indigenous communities.

The (dis)engagement of mangrove forests and mangrove rice in academic and non-academic literature on Guinea-Bissau-a systematic review protocol.

Coastal areas in Guinea-Bissau and elsewhere in West Africa are bordered by mangrove forests. In several of these places, swaths of mangrove forest have been removed and the landscape has been technologically adapted for the production of mangrove rice-a regionally important staple. However, the effects of global warming, in particular sea-level rise, pose challenges to these socioecological environments. In this context, knowledge appears as an important resource and knowing what knowledge has been produced and which perspectives have guided that production may inform future responses to climate change. We have developed a systematic literature review protocol focusing on the main question: "How have mangrove forest and mangrove rice spaces been represented in the literature on Guinea-Bissau?" The main hypothesis is that although they occupy contiguous, interrelated and interactant spaces in coastal environments, mangrove forests and mangrove rice have been studied and analyzed independently in the literature. This is a protocol for conducting a systematic review that will include academic and non-academic literature in Portuguese, English and French. The academic literature will be retrieved from both Web of Science and Scopus using Boolean expressions. The non-academic literature will be accessed from relevant institutions, specialized libraries, and reference lists of previously selected items. Data extraction will follow a standard procedure based on an information sheet. Our analysis will be both qualitative (inductive and deductive coding, content analysis) and quantitative (word clouds, descriptive statistics and statistical testing). This systematic review will provide information about the conceptual framework that has been produced through research, policymaking, and conservation and development programs in the management of coastal areas. This study will identify the limitations of previous approaches and contribute to both future research and strategies for planning adaptation to climate change. Finally, the outputs will add to broader debates about people-nature coexistence and climate change adaptation and mitigation.

Land Use Zoning Management to Coordinate the Supply–Demand Imbalance of Ecosystem Services: A Case Study in the City Belt Along the Yellow River in Ningxia, China

The imbalance between the supply and demand of ecosystem services (ESs) is one of the main reasons for ecological degradation, which significantly impacts human well-being and ecological safety. Spatial heterogeneity of ES supply–demand, ES tradeoffs, and the socioecological environment calls for zoning management, while few studies have combined the above three aspects in dividing management zones and proposed strategies. Using the City Belt along the Yellow River in Ningxia in northwestern China as a case study, this study quantified the supply and demand for five key ESs (crop production, carbon sequestration, nutrient retention, sand fixation, and recreational opportunity), analyzed ES tradeoffs/synergies and bundles through correlation analysis and the self-organizing map (SOM) method, and investigated their socioecological driving mechanisms through a random forest model and the SOM method. Management zones were proposed and differentiated suggestions were provided through overlaying ES bundles and driver clusters. The results suggested that crop production, carbon sequestration, and nutrient retention mostly correlated to the same intrinsic ecological process, resulting in consistent synergies among these three ESs at both supply and demand sides. On the contrary, the variance in interactions between the two ESs of sand fixation and recreational opportunity and the other three ESs is due to the low similarity of their intrinsic ecological processes and external driving mechanisms. Fourteen socioecological factors could effectively explain the spatial heterogeneity of ES supply, demand, and match degree. Fourteen management zones with similar ecological problems and socioecological environments were delineated, and differentiated suggestions were provided for each zone. Adopting both ES characteristics and the socioecological environment into zoning management could effectively detect ecological problems and help to promote management suggestions in different socioecological contexts. This framework could offer new insights for integrating ESs into actual decision-making and ecosystem management.

Drivers of Dyadic Cofeeding Tolerance in Pan: A Composite Measure Approach.

Simple SummaryIn this study on zoo-housed chimpanzees and bonobos, we propose a novel operational measure to quantify how tolerantly animals cofeed around a food source. Using an experimental set-up, we measured five behavioral variables that reflect positive and negative aspects of cofeeding behavior. Using a dimension reduction analysis technique, we found a two-dimensional tolerance model that we labeled “Tolerant Cofeeding” and “Agonistic Cofeeding”. In both species, scores on these two dimensions were predicted by sex, relatedness and social bonds in a similar fashion. High-value relationships between individuals that consist in mutual affiliation and support during aggressive interactions resulted in higher tolerance around food sources, while highly competitive dyads that show more mutual aggression showed lower tolerance. Bonobos and chimpanzees did not differ in their overall cofeeding tolerance, which likely reflects their adaptability to fluctuating social and ecological circumstances. This methodology can now be applied to other animal species to further investigate how variation in social and ecological environments influences the tolerance levels of social bonds, both at the dyadic and group level.This study aimed to construct a composite model of Dyadic Cofeeding Tolerance (DCT) in zoo-housed bonobos and chimpanzees using a validated experimental cofeeding paradigm and to investigate whether components resulting from this model differ between the two species or vary with factors such as sex, age, kinship and social bond strength. Using dimension reduction analysis on five behavioral variables from the experimental paradigm (proximity, aggression, food transfers, negative food behavior, participation), we found a two-factor model: “Tolerant Cofeeding” and “Agonistic Cofeeding”. To investigate the role of social bond quality on DCT components alongside species effects, we constructed and validated a novel relationship quality model for bonobos and chimpanzees combined, resulting in two factors: Relationship Value and Incompatibility. Interestingly, bonobos and chimpanzees did not differ in DCT scores, and sex and kinship effects were identical in both species but biased by avoidance of the resource zone by male–male dyads in bonobos. Social bonds impacted DCT similarly in both species, as dyads with high Relationship Value showed more Tolerant Cofeeding, while dyads with higher Relationship Incompatibility showed more Agonistic Cofeeding. We showed that composite DCT models can be constructed that take into account both negative and positive cofeeding behavior. The resulting DCT scores were predicted by sex, kinship and social bonds in a similar fashion in both Pan species, likely reflecting their adaptability to changing socio-ecological environments. This novel operational measure to quantify cofeeding tolerance can now be applied to a wider range of species in captivity and the wild to see how variation in local socio-ecological circumstances influences fitness interdependence and cofeeding tolerance at the dyadic and group levels. This can ultimately lead to a better understanding of how local environments have shaped the evolution of tolerance in humans and other species.

Engaging with precarious urban futures: From entrepreneurial to grounded cities

In order to answer the question posed by the conference Urban Europe, Precarious Futures? the article examines the relationship between rising precariousness,the need for social-ecological transformation to keep socio-ecological environments manageable for future generations of Europeans and the provision of urban reliance systems as the key pillar of a possible transformation toward life within the planetary boundaries. The article has four goals: First, it establishes a link between the literatures on precarization, three possible political-economic development scenarios, and resulting modes of urban governance. Second, it develops the normative but theoretically and empirically backed claim that a strengthening of the foundational economy appears most suited to produce the necessary reductions in precarious living conditions and environmental destruction required for a socially and ecologically sustainable future. Third, the urban scale is argued to occupy a privileged position as a growing site of human habitation in Europe and for the design and provision of foundational infrastructure and universal basic services. The article links cities to the foundational economy via the concept of the Grounded City. Fourth, research on the provision of universal basic services in the City of Vienna is employed to illustrate that a narrow focus on cities as territorial-administrative containers ignoring their inter-territorial and inter-scalar relations is likely to produce socio-spatial rebound effects that may neutralize the gains of social-ecological investment in cities. Any effective social-ecological transformation thus requires coordination, cooperation, lobbying and political change at all scales of governance. In the European case, it requires the European Union to evolve from an economic to a social-ecological Union and for urban governance regimes across Europe to be altered to take into account the horizontal and intra-scalar relations that co-constitute cities.

Psychosocial and energetic factors on human female pubertal timing: a systematized review.

Childhood psychosocial stressors have been proposed to favour fast life history strategies promoting earlier puberty in females. However, studies demonstrating this association often do not elucidate causal mechanisms, nor account for greater childhood energetic availability - also known to promote rapid growth and earlier puberty. To assess the extent to which such confounding has been considered, we conducted a systematized review to identify studies examining measures of both prepubertal growth (e.g. weight, height) and psychosocial stressors (e.g. adversity, father absence) in relation to female pubertal timing. A total of 1069 non-duplicated studies were identified across five databases. Twenty studies met selection criteria for critical review following independent screening of titles, abstracts and manuscripts. Within these studies, measures indicative of rapid childhood growth were more consistently associated with earlier pubertal timing than were measures of psychosocial stress. We discuss future research directions to investigate the impact of psychosocial stress on pubertal timing more robustly, including methodological and mechanistic considerations, and contextualization of findings by socioecological environments.

Orangutans have larger gestural repertoires in captivity than in the wild—A case of weak innovation?

SummaryWhether nonhuman species can change their communicative repertoire in response to socio-ecological environments has critical implications for communicative innovativeness prior to the emergence of human language, with its unparalleled productivity. Here, we use a comparative sample of wild and zoo-housed orangutans of two species (Pongo abelii, Pongo pygmaeus) to assess the effect of the wild-captive contrast on repertoires of gestures and facial expressions. We find that repertoires on both the individual and population levels are larger in captive than in wild settings, regardless of species, age class, or sampling effort. In the more sociable Sumatran species, dominant use of signals toward single outcomes was also higher in captive settings. We thus conclude that orangutans exposed to more sociable and terrestrial conditions evince behavioral plasticity, in that they produce additional innate or innovated signals that are highly functionally specific. These findings suggest a latent capacity for innovativeness in these apes' communicative repertoires.

Balancing costs and benefits in primates: ecological and palaeoanthropological views.

Maintaining the balance between costs and benefits is challenging for species living in complex and dynamic socio-ecological environments, such as primates, but also crucial for shaping life history, reproductive and feeding strategies. Indeed, individuals must decide to invest time and energy to obtain food, services and partners, with little direct feedback on the success of their investments. Whereas decision-making relies heavily upon cognition in humans, the extent to which it also involves cognition in other species, based on their environmental constraints, has remained a challenging question. Building mental representations relating behaviours and their long-term outcome could be critical for other primates, but there are actually very little data relating cognition to real socio-ecological challenges in extant and extinct primates. Here, we review available data illustrating how specific cognitive processes enable(d) modern primates and extinct hominins to manage multiple resources (e.g. food, partners) and to organize their behaviour in space and time, both at the individual and at the group level. We particularly focus on how they overcome fluctuating and competing demands, and select courses of action corresponding to the best possible packages of potential costs and benefits in reproductive and foraging contexts. This article is part of the theme issue 'Existence and prevalence of economic behaviours among non-human primates'.

The feasibility and acceptability of mobile health monitoring for real-time assessment of traumatic injury outcomes.

Traumatic injuries are a health event that can begin a trajectory towards chronic health and social challenges. Mobile technology-based prevention and treatment interventions have been used to monitor and transform outcomes across a myriad of health conditions, but their potential in long-term injury recovery is unexplored. The goal of this pilot study was to assess the acceptability and feasibility of mobile health monitoring for long-term outcomes in a population of trauma patients with known barriers to health and social care after injury. We re-recruited 25 individuals, 12-36 months after acute hospitalization, from a recently concluded study of psychological outcomes in seriously injured Black men in Philadelphia, Pennsylvania. This mixed- methods pilot study was conducted in three phases: (I) qualitative interviews and development of a pilot monitoring platform; (II) a 3-month feasibility trial of mobile monitoring of patient-reported outcomes and biometric data using a wrist-worn commercial fitness monitor (n=18); (III) post-implementation qualitative interviews. Analysis of data from pre-implementation interviews indicated that the majority of participants used smartphones as a primary means of communicating with their social network and to access the internet. The 90-day pilot trial of mobile monitoring indicated participants' preference text-delivered communication and survey elicitation. Response rates for 12 automated surveys ranged from 84-92%. Twenty-four hours a day adherence to optional biometric monitoring was generally lower than 50% but ranged widely indicating both very low adherence and very high adherence. Four of 25 participants, 2 who had opted for Fitbit monitoring, were lost to follow-up at the end of the 90-day pilot trial. In post-implementation assessments, participants endorsed the acceptability of mobile monitoring highlighting the benefit of its convenience and flexibility over in-person outcome monitoring. Participants also perceived its potential benefit in long-term engagement with health and social services to assist with the challenges they faced when attempting to achieve physical, psychological, social, and financial recovery after hospitalization. These findings were reinforced through qualitative interviews which highlighted, in addition to acceptability, the perceived value of self-monitoring through the use of wearable devices to track health data like physical activity and sleep. This study indicates the feasibility and acceptability of mobile health monitoring used to examine long-term injury sequalae. Future research may leverage this novel strategy, refining its application to address current limitations in the reliability and accuracy of commercially available wearable technology, relative costs and benefits of different mobile data collection strategies, integration within current clinical paradigms and generalizability across injured populations and socio-ecological environments.

“I just trust what Google says, it’s the Bible”: Exploring young, Black gay and other men who have sex with men’s evaluation of sexual health information sources in Toronto, Canada

While sexual health literature identifies youths’ sexual health information sources and its impact on their sexual practices, little is known about the way youth evaluate the credibility of this information. This knowledge gap is significant among young, Black gay and other men who have sex with men (YBGM) who belong to intersectional populations disproportionately impacted by HIV and other STIs. We conducted a qualitative study using constructivist grounded theory to explore YBGM’s approaches to evaluating sexual health information sources’ credibility. Intersectionality and the socioecological model informed our analysis. We explored connections between social locations (e.g., race, sexual orientation) and socio-ecological environments and how their impact shaped YBGM’s evaluation of sexual health information. Findings revealed evaluation strategies varied by source: friends, the internet and healthcare providers. Friends’ information was deemed credible if they were older, shared social locations and provided embodied testimonials. Testimonials mirrored oral-traditions specific to Black populations where oral narratives help disseminate sensitive information in a culturally relevant way. Website selection was informed by YBGM’s social locations and ranged from being implicitly trusted to assessed by its association with established healthcare organizations. Many participants’ acceptance of healthcare providers’ information revealed patient-client power imbalances and a perception that providers’ actions reflected their institutions’ sexual health policies. Findings highlight a need for sexual health services to create culturally effective ways to disseminate information that accounts for the histories, contexts, and approaches YBGM use to identify credible sources of sexual health information.

Unpacking chimpanzee (Pan troglodytes) patch use: Do individuals respond to food patches as predicted by the marginal value theorem?

The marginal value theorem is an optimal foraging model that predicts how efficient foragers should respond to both their ecological and social environments when foraging in food patches, and it has strongly influenced hypotheses for primate behavior. Nevertheless, experimental tests of the marginal value theorem have been rare in primates and observational studies have provided conflicting support. As a step towards filling this gap, we test whether the foraging decisions of captive chimpanzees (Pan troglodytes) adhere to the assumptions and qualitative predictions of the marginal value theorem. We presented 12 adult chimpanzees with a two-patch foraging environment consisting of both low-quality (i.e., low-food density) and high-quality (i.e., high-food density) patches and examined the effect of patch quality on their search behavior, foraging duration, marginal capture rate, and its proxy measures: giving-up density and giving-up time. Chimpanzees foraged longer in high-quality patches, as predicted. In contrast to predictions, they did not depress high-quality patches as thoroughly as low-quality patches. Furthermore, since chimpanzees searched in a manner that fell between systematic and random, their intake rates did not decline at a steady rate over time, especially in high-quality patches, violating an assumption of the marginal value theorem. Our study provides evidence that chimpanzees are sensitive to their rate of energy intake and that their foraging durations correlate with patch quality, supporting many assumptions underlying primate foraging and social behavior. However, our results question whether the marginal value theorem is a constructive model of chimpanzee foraging behavior, and we suggest a Bayesian foraging framework (i.e., combining past foraging experiences with current patch sampling information) as a potential alternative. More work is needed to build an understanding of the proximate mechanisms underlying primate foraging decisions, especially in more complex socioecological environments.

Social relationships among adult male chimpanzees (Pan troglodytes schweinfurthii): variation in the strength and quality of social bonds

Socioecological environments that promote frequent interaction and social tolerance have favored the evolution of strong and equitable social bonds, which facilitate cooperation and confer fitness benefits. In most species, kinship is the primary predictor of bond strength and quality, but it does not adequately explain partner choice among adult male chimpanzees. Instead, most bonds and cooperative interactions occur among unrelated individuals, likely because of a lack of brothers among available partners. To identify what factors drive partner choice when kinship does not, we investigated the strength and quality of social bonds among adult male chimpanzees (N = 26) at Gombe National Park, Tanzania. Maternal brothers, when present, formed stronger bonds than other dyads, and maternal brothers who were close in age or rank formed the strongest bonds. Among dyads that were not maternal brothers, however, the strength of social bonds was not associated with either age difference or rank difference. Additionally, dyads with stronger bonds groomed more equitably than other dyads, as did maternal brothers and dyads close in rank. Bonds were stable, community-wide, for 2 years on average, while lasting up to 13 years. Overall, there remains no clear-cut explanation for partner choice among male chimpanzees. Demographic constraints limit the impact of kinship, and the effects of age and rank difference are small or nonexistent, suggesting that bond strength results from a more complex process than a simple accounting of basic characteristics. Instead, dyads may possess some distinct quality that engenders strength and stability, such as compatible personalities. Strong social ties are associated with increased fitness in several species, including humans, baboons, feral horses, and dolphins. Although close kin typically form the strongest bonds, kinship explains only a limited number of bonds (and associated cooperation) among adult male chimpanzees. To identify what factors influence partner choice when kinship does not, we examined social bonds among adult male chimpanzees at Gombe National Park, Tanzania. Males formed strong, stable bonds and groomed more equitably with strong bond partners. Nevertheless, kinship, age difference, and rank difference did not fully explain male partner choice. These results contrast with findings in other species, where stronger and more equitable bonds are typically formed by kin as well as those that are close in age and rank. Instead, male chimpanzee dyads may possess some distinct quality that promotes strength and stability, such as compatible personalities.

Foundations of morality in Iran

Most moral psychology research has been conducted in Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies. As such, moral judgment, as a psychological phenomenon, might be known to researchers only by its WEIRD manifestations. Here, we start with evaluating Moral Foundations Theory (MFT) using the Moral Foundations Questionnaire, and follow up by building a bottom-up model of moral values, in Iran, a non-WEIRD, Muslim-majority, understudied cultural setting. In six studies ( N = 1945) we examine the structural validity of the Persian translation of the Moral Foundations Questionnaire, compare moral foundations between Iran and the US, conduct qualitative interviews regarding moral values, expand the nomological network of “Qeirat” as a culture-specific set of moral values, and investigate the pragmatic validity of “Qeirat” in Iranian culture. Our findings suggest an additional moral foundation in Iran, above and beyond the five foundations identified by MFT. Specifically, qualitative studies highlighted the role of “Qeirat” values in Iranian culture, which are comprised of guarding and protectiveness of female kin, romantic partners, broader family, and country. Significant cultural differences in moral values are argued in this work to follow from the psychological systems that, when brought to interact with particular socio-ecological environments, produce different moral structures. This evolutionarily-informed, cross-cultural, mixed-methods research sheds light on moral concerns and their cultural, demographic, and individual-difference correlates in Iran.

Age differences in the temporal stability of a male African elephant (Loxodonta africana) social network

AbstractSocial animals live in complex and variable socio-ecological environments where individuals adapt their behavior to local conditions. Recently, there have been calls for studies of animal social networks to take account of temporal dynamics in social relationships as these have implications for the spread of information and disease, group cohesion, and the drivers of sociality, and there is evidence that maintaining stable social relationships has fitness benefits. It has recently been recognized that male elephants form strong social bonds with other males. The nature of these relationships, and thus network structure, may vary over time in response to varying environmental conditions and as individuals age. Using social network analysis, we examine the stability of relationships and network centrality in a population of male African elephants. Our results suggest that males may maintain stable social relationships with others over time. Older males show greater stability in network centrality than younger males, suggesting younger males face uncertainty in transitioning to adult society. For elephants, where older individuals function as social repositories of knowledge, maintaining a social network underpinned by older males could be of particular importance.

“Doing our best to keep a routine:” How low-income mothers manage child feeding with unpredictable work and family schedules

Significant changes in work and family conditions over the last three decades have important implications for understanding how young children are fed. The new conditions of work and family have placed pressures on families. The aim of this study was to explore the work and family pressures shaping the ways parents feed their young children on a day-to-day basis. Twenty-two purposively recruited low-income employed mothers of 3–4 year old children from a rural county Head Start program in Upstate New York reported details about the context of their children's eating episodes in a 24-h qualitative dietary recall. Participating mothers were employed and/or in school at least 20 h a week and varied in partner and household characteristics. Interview transcripts were open coded using the constant comparative method for usual ways of feeding children. A typology of three emergent child feeding routines was identified based on mothers' accounts of the recurring ways they fed their child. Mothers' feeding routines were distinguished by a combination of four recurring key strategies – planning ahead, delegating, making trade-offs, and coordinating. Work schedule predictability and other adults helped mothers maintain feeding routines. Unexpected daily events, such as working overtime or waking up late, disrupted child feeding routines and required modifications. These findings suggest that understanding how young children are fed requires recognizing the socio-ecological environments that involve working mothers' daily schedules and household conditions and the multiple ways that mothers manage food and feeding to fit environmental constraints. There is a need to look at more than just family meals to understand parents' daily strategies for feeding young children and their implications for child nutrition.
