The Embedded Conundrum of South-South and Triangular Cooperation: A Prologue to Shifting Frontiers from Collaboration to Contention

This special issue discusses, in-depth, the embedded conundrum of South-South and triangular cooperation (SSTC) whose frontiers are shifted from collaboration to contention within the United Nations (UN) development system and beyond. This introductory article provides the conceptual framework—the contentioncollaboration spectrum—that guides all the contributors and serves as the collective starting point for this project. The moving frontiers of SSTC reflect the shifting historic relationships between the global South and North as well as Southern partner countries. The framework enables the six articles of this special issue to investigate the paradoxical structure of contrasting dynamics of SSTC, which has always been exposed to historical transformations at multi-levels of analysis: global governance, regional engagements, middle power perspectives, and the UN development system and beyond.

Film as Fabric: A visual essay signalling the importance of clothing in expanded cinema performance

In this visual essay, I discuss how clothing made for an expanded cinema performance entitled Film as Fabric took on significance. The live work shows analogue film as fabric and stitching as editing to highlight historical relationships between textile practice and experimental filmmaking. The work developed through iterations from 2013 to 2017 as a part of doctorate research carried out from 2012 to 2020. My position as an experimental filmmaker with a background in embroidery grounded the study. Annabel Nicolson’s seminal live expanded cinema performance Reel Time (1973), in which she punctured 16mm film with her unthreaded sewing machine, was also a point of departure. Feminist critique from both disciplines – film and textile studies – supported the possibility of repressed relationships between the fields. Feminist scholars have repeatedly problematized contextualization of experimental filmmaking as narrow and misplaced (Blaetz 2007; Hatfield 2006; Reynolds 2009, ; ). Until now, connections with textile practice in experimental filmmaking have been largely overlooked, most likely because domestic crafts have a long association with women’s work (), are central to deep rooted Western stereotypes of femininity, and remain denigrated art forms (). The development of Film as Fabric led to the creation of hybrid tools, forms and gestures, such as optical sounds and moving images made from fabric and stitch patterns. These were measured on the body, cut with dressmaking scissors, stitched, spliced into loops and projected in former cotton mills. This process allowed sounds associated with textile production and my personal textile ancestry to re-surface in new ways. The live context demands attention is given to material practices, which typically take place out of sight in the home and the film cutting room and have also recently undergone significant shifts in cultural status.

Refining the chronology of North America's copper using traditions: A macroscalar approach via Bayesian modeling.

North America’s ancient copper use, predicted to originate as early as 9000 cal BP, represents the earliest use of native copper for utilitarian tool production in the world. Although recent work has focused on establishing the first use of copper in the western Great Lakes region, little attention has been paid to determining the age ranges of subsequent copper using groups or to the identification of broader trends in copper use during the Archaic Period (10,000–3000 RCYBP). Here we address this issue by applying Bayesian modeling to a comprehensive suite of 76 radiocarbon dates directly associated with copper use. Our results identified two distinct peaks in copper usage, ca. 5500 cal BP and ca. 3300 cal BP. Age ranges for the three Archaic Period traditions and practices associated with copper use of the western Great Lakes are revised using modern calibration curves. Bayesian revisions of age ranges from sites where copper tools and/or production debris have been found provide insight into the historical relationships between, and cultural interactions among, these early copper using groups. This study provides an updated, refined chronology based on the most recent calibration curve (IntCal20) for the varied cultural contexts of copper use across the western Great Lakes.

Population Genomics of New Zealand Pouched Lamprey (kanakana; piharau; Geotria australis).

Pouched lamprey (Geotria australis) or kanakana/piharau is a culturally and ecologically significant jawless fish that is distributed throughout Aotearoa New Zealand. Despite its importance, much remains unknown about historical relationships and gene flow between populations of this enigmatic species within New Zealand. To help inform management, we assembled a draft G. australis genome and completed the first comprehensive population genomics analysis of pouched lamprey within New Zealand using targeted gene sequencing (Cyt-b and COI) and restriction site-associated DNA sequencing (RADSeq) methods. Employing 16 000 genome-wide single nucleotide polymorphisms (SNPs) derived from RADSeq (n = 186) and sequence data from Cyt-b (766 bp, n = 94) and COI (589 bp, n = 20), we reveal low levels of structure across 10 sampling locations spanning the species range within New Zealand. F-statistics, outlier analyses, and STRUCTURE suggest a single panmictic population, and Mantel and EEMS tests reveal no significant isolation by distance. This implies either ongoing gene flow among populations or recent shared ancestry among New Zealand pouched lamprey. We can now use the information gained from these genetic tools to assist managers with monitoring effective population size, managing potential diseases, and conservation measures such as artificial propagation programs. We further demonstrate the general utility of these genetic tools for acquiring information about elusive species.

How Japanese Universities Develop Study Abroad Programs in Southeast Asia: A Sensemaking Perspective

Despite extensive research on the push-pull factors of student motivation to study abroad, there has been little examination of university academics’ and administrators’ attitudes as program developers and providers. This research draws upon the literature of sensemaking to investigate how and why Japanese university academics and administrators develop study abroad programs in Southeast Asia. The analysis reveals that university academics and administrators balance the characteristics of their university and student demands with advantages to themselves. Involvement with study abroad allows academics to promote their research, attract students to their field, and compete with other departments. Administrators seek to increase their involvement in education through collaboration with academics. Furthermore, both academics and administrators recognize that the involvement of Southeast Asian graduates of Japanese universities can facilitate the development of study abroad programs in Southeast Asia. This social analysis highlights the historical and educational relationships between Japan and Southeast Asia and provides a new perspective for the analysis of not only motivations, but also the processes that lead from motivations to actions.

Abjection Incorporated: Mediating the Politics of Pleasure and Violence

Abjection Incorporated: Mediating the Politics of Pleasure and Violence

The Tibetan-Yi region is both a corridor and a barrier for human gene flow.

The Tibetan-Yi Corridor (TYC) region between Tibet and the rest of east Asia has served as a crossroads for human migrations for thousands of years. The lack of whole-genome sequencing data specific to the TYC populations has hindered the understanding of the fundamental patterns of migration and divergence between humans in east Asia and southeast Asia. Here, we provide 248 individual whole genomes from the 16 TYC and 3 outgroup populations to elucidate historical relationships. We find that the Tibetan plateau forms an important barrier to gene flow, with a more Tibetan-like ancestry in northern populations and a southern east Asian-related ancestry in south populations. An isolated population, Achang, shows a prolonged isolation and genetic drift compared to other TYC populations. We also note that previous claims regarding the history and structure of TYC populations inferred by linguistics are incompatible with the genetic evidence.

A poetics of parallax: The significant geographies of Derek Walcott’s Omeros (1990)

ABSTRACT Tracing the interplay between different scales of language, narrative, and geography in Omeros (1990), this article analyses the activity of parallax within Derek Walcott’s aesthetic, and its broader significance for the relationship between postcolonial literature and space. It argues Omeros evidences Walcott’s development of a poetics of parallax, and analyses this poetics in a way that builds on recent critical developments such as the focus on “significant geographies”, as well as on established critical distinctions, primarily that between style and plot. By analysing the negotiation of different scales of attention across the poem – from local depiction characterized by heightened style to the insistence on spatial and historical relationships that elude style’s descriptive powers – this article connects formal and stylistic readings with the text’s geopolitical imagination. The result provides a new angle on the poem’s negotiation of Homeric sources, and its delineation of the tensions and pressures that criss-cross postcolonial spatiality.

Opening a door to the spatiotemporal history of plants from the tropical Indochina Peninsula to subtropical China

The complexity of global biodiversity in the tropical Indochina Peninsula and subtropical China bioregions has fascinated biologists for decades, but little is known about the spatiotemporal patterns in these regions. Accordingly, the aims of present study were to investigate the evolutionary and distribution patterns of Engelhardia in these regions and establish a model for examining biogeographic patterns and geological events throughout the tropical Indochina Peninsula and subtropical China. The effects of geological events occurring in the area between the Indochina Peninsula and subtropical China bioregions on the two trees species (i.e., E. roxburghiana and E. fenzelii) were evaluated. A robust phylogenetic framework of 884 individuals from 79 populations was used to generate time-calibrated cytoplasmic and nuclear phylogenetic frameworks based on cpDNA, nrDNA, and nSSR data, respectively. When considered along with ancestral area reconstructions, the genetic data were also used to assess and reconstruct the species’ population genetic structure and diversity. These analyses yielded important information about the (1) historical distribution relationships between the tropical and subtropical flora of China; (2) effects of the East Asian summer monsoon (EASM) on the evolutionary history of Asia’s plants; and (3) importance of biogeography in conservation planning. Although cytoplasmic-nuclear discordance indicated cpDNA and nrDNA were subject to distinct evolutionary mechanisms that reflected respective evolutionary histories of the plastid and nuclear genomes of prior demographic and biogeographic events. The tropical elements of Engelhardia occupied the Indochina Peninsula during the early Eocene, whereas the subtropical elements were transformed from the tropical elements during Miocene cooling and the onset of the EASM at the Oligocene-Miocene boundary, intensified during the late Miocene and Pliocene, facilitating the transformation of Engelhardia from the tropical Indochina Peninsula to subtropical China. Demographic history provided insights into prominent planning frameworks in conservation biology, namely that subtropical China functioned as a refugium during past climate oscillations and will continue to serve in this capacity in the future.

Educating Through Attentional States of Consciousness, an Effective Way to Develop Creative Potential?

Researchers have recently turned their focus to a specific area: the links between altered states of consciousness and creativity. A spectrum of attentional states of consciousness exists, from hypnagogia and mind wandering to mindfulness and flow. These attentional states of consciousness are present during a variety of activities (e.g., sports, music, painting, writing, video games, theater, and meditation) as well as in situations characterized by boredom. They are also present in many professional fields and practices (e.g., education and teaching). Moreover, researchers and educators focus sometimes on only one state of consciousness (such as mind wandering) or only on attention, and do not question relationships with others (such as mindfulness or flow) or the links with intention, the different levels of consciousness involved and the changes in perception of time, self and space. Additionally, as we know that a state of consciousness rarely occurs alone or that it can have two forms (such as spontaneous and deliberate mind wandering), we propose a global approach allowing to grasp the stakes and perspectives of what we call attentional states of consciousness. Thus, to our knowledge, this is the first theoretical review highlighting the historical, empirical, theorical and conceptual relationships between creativity, attention, mind wandering, mindfulness and flow by offering concrete and empirical avenues and bases for reflection about educating for creativity and developing creative potential.

Continuing Connection

The historical relationships between Makassans and Aboriginal people that took place as early as the 17th century until the early 20th century through the trepang industry in the northern coast, North Australia, is still unknown to many people in Makassar, South Sulawesi. There are various factors involved in the lack of information about the shared history, including the absence of the story of trepangers as part of Indonesian maritime heritage history in school textbooks and the insufficient materials and narratives on this topic in provincial and city museums. This paper examines the potential roles of Makassan artists and cultural activists to tell the story after engaging with ancient trepang industry-related cultural and art projects. It also investigates their changed perceptions about Australia and Indonesia both culturally and historically after their participation in art and cultural projects.

Maternal Relationships among Ancient and Modern Southern African Sheep: Newly Discovered Mitochondrial Haplogroups.

Simple SummaryThe genetic diversity of southern African sheep remains under-studied. We present here the complete mitochondrial genomes of archaeological southern African sheep, as well as the genomes from three indigenous southern African breeds—Damara, Namaqua Afrikaner, and Ronderib Afrikaner. We show that southern African sheep exhibit limited genetic diversity which is consistent with our understanding of their migration south from northernmost Africa. Intriguingly, many of the modern sheep show close relationships with the archaeological sheep, implying an ancestor-descendant relationship. Similarly, the sheep that do not exhibit a close relationship with the archaeological sheep nonetheless cluster closely with each other and do not show a close relationship with European and Asian sheep. This suggests that they too are descendants of indigenous sheep and not the product of historic introductions of exotic breeds.We investigated the genetic diversity and historic relationships among southern African sheep as well as the relationships between them and sheep outside the continent by sourcing both archaeological and modern sheep samples. Archaeological sheep samples derived from the site Die Kelders 1, near Cape Town, date to approximately 1500 years ago. The modern samples were taken as ear snips from Damara, Namaqua Afrikaner, and Ronderib Afrikaner sheep on a farm in Prieska in the Northern Cape. Illumina sequencing libraries were constructed for both ancient and modern specimens. Ancient specimens were enriched for the mitochondrial genome using an in-solution hybridization protocol and modern specimens were subjected to shotgun sequencing. Sequences were mapped to the Ovis aries reference genome, assigned to haplogroups and subhaplogroups, and used to calculate a phylogenetic tree using previously published, geographically dispersed mitochondrial genome sheep sequences. Genetic diversity statistics show that southern African sheep have lower diversity than sheep in other regions. Phylogenetic analysis reveals that many modern southern African sheep are likely descended from prehistoric indigenous sheep populations and not from sheep imported from Europe during the historic period.

“I Just Couldn’t Relate to That Asian American Narrative”: How Southeast Asian Americans Reconsider Panethnicity

Asian American panethnicity was conceptualized to unify ethnic groups and represent their sociopolitical interests. Increasingly however, scholars have questioned whether panethnicity accurately reflects the diversity of different ethnic groups’ experiences and identities. In mainstream culture, “Asian American” has become synonymous with East Asian Americans and stereotypes—albeit biased ones—of their affluence, thus erasing the realities of working-class, South, and Southeast Asian Americans (SEAAs). I focus on the last group and join other scholars in emphasizing how ethnic groups’ unique historical relationships with the United States differentially impact their racial identities and attachments to panethnicity. Using 62 interviews with Southeast Asian refugees and service providers in North Carolina, I explore how a term I call “quiet neglect”—the U.S. institutionalized silence around the Vietnam and Secret Wars that has led to an erasure of SEAAs’ needs—shape their connections to Asian American panethnicity and decision to align with alternative identities. At stake in this study is our capacity to recognize individuals’ agency to challenge racial boundaries and assert identities that they find meaningful. In addition, I examine how SEAAs situate themselves within our broader racial structure and harness their identities to connect with other people of color.

Origin and Diversification of the Saguaro Cactus (Carnegiea gigantea): A Within-Species Phylogenomic Analysis.

Reconstructing accurate historical relationships within a species poses numerous challenges, not least in many plant groups in which gene flow is high enough to extend well beyond species boundaries. Nonetheless, the extent of tree-like history within a species is an empirical question on which it is now possible to bring large amounts of genome sequence to bear. We assess phylogenetic structure across the geographic range of the saguaro cactus, an emblematic member of Cactaceae, a clade known for extensive hybridization and porous species boundaries. Using 200 Gb of whole genome resequencing data from 20 individuals sampled from 10 localities, we assembled two data sets comprising 150,000 biallelic single nucleotide polymorphisms (SNPs) from protein coding sequences. From these, we inferred within-species trees and evaluated their significance and robustness using five qualitatively different inference methods. Despite the low sequence diversity, large census population sizes, and presence of wide-ranging pollen and seed dispersal agents, phylogenetic trees were well resolved and highly consistent across both data sets and all methods. We inferred that the most likely root, based on marginal likelihood comparisons, is to the east and south of the region of highest genetic diversity, which lies along the coast of the Gulf of California in Sonora, Mexico. Together with striking decreases in marginal likelihood found to the north, this supports hypotheses that saguaro's current range reflects postglacial expansion from the refugia in the south of its range. We conclude with observations about practical and theoretical issues raised by phylogenomic data sets within species, in which SNP-based methods must be used rather than gene tree methods that are widely used when sequence divergence is higher. These include computational scalability, inference of gene flow, and proper assessment of statistical support in the presence of linkage effects.

Assessment of the hydrological drought risk in Calgary, Canada using weekly river flows of the past millennium

Abstract Planning and management of water resource infrastructure requires a depth of knowledge on the characteristics of hydrological extremes, floods and droughts. Infrastructure design is traditionally based upon historically observed extreme events, assuming that they are independent and identically distributed (i.i.d.) and stationary, i.e. they fluctuate within a fixed envelope of variability. Information on historical hydroclimate provides a limited range of hydrological extremes, which rarely includes long-term worst droughts. This study demonstrates the application of a paleo-environmental dataset, 900 years of weekly streamflow stochastically derived from a tree-ring reconstruction of annual streamflow, to assess the hydrological drought risk. The historic and prehistoric hydrological drought characteristics, i.e. severity–duration–frequency (SDF) relationships, are evaluated. The results indicate that the severity and duration of hydrological drought with the same recurrence interval is substantially larger and longer than those observed over the 100-year historical period. Historic and prehistoric drought SDF relationships established in this study demonstrate the implications of non-stationary climate in the analysis of extreme droughts. Therefore, projected droughts of the 21st century may not exceed the drought severity found in the prehistoric record to the same extent that they exceed historical droughts in the instrumental record. This study emphasizes the importance of paleohydrology in comprehending the region's drought.

Reduced genetic diversity associated with the northern expansion of an amphibian species with high habitat specialization, Ascaphus truei, resolved using two types of genetic markers.

Reconstruction of historical relationships between geographic regions within a species’ range can indicate dispersal patterns and help predict future responses to shifts in climate. Ascaphus truei (coastal tailed frog) is an indicator species of the health of forests and perennial streams in the Coastal and Cascade Mountains of the Pacific Northwest of North America. We used two genetic techniques—microsatellite and genotype‐by‐sequencing (GBS)—to compare the within‐region genetic diversity of populations near the northern extent of the species’ range (British Columbia, Canada) to two geographic regions in British Columbia and two in Washington, USA, moving toward the core of the range. Allelic richness and heterozygosity declined substantially as latitude increased. The northernmost region had the lowest mean expected heterozygosities for both techniques (microsatellite, M = 0.20, SE = 0.080; GBS, M = 0.025, SE = 0.0010) and the southernmost region had the highest (microsatellite, M = 0.88, SE = 0.054; GBS, M = 0.20, SE = 0.0029). The northernmost regions (NC and MC) clustered together in population structure models for both genetic techniques. Our discovery of reduced diversity may have important conservation and management implications for population connectivity and the response of A. truei to climate change.

Growing impact of wildfire on western US water supply

Streamflow often increases after fire, but the persistence of this effect and its importance to present and future regional water resources are unclear. This paper addresses these knowledge gaps for the western United States (WUS), where annual forest fire area increased by more than 1,100% during 1984 to 2020. Among 72 forested basins across the WUS that burned between 1984 and 2019, the multibasin mean streamflow was significantly elevated by 0.19 SDs (P < 0.01) for an average of 6 water years postfire, compared to the range of results expected from climate alone. Significance is assessed by comparing prefire and postfire streamflow responses to climate and also to streamflow among 107 control basins that experienced little to no wildfire during the study period. The streamflow response scales with fire extent: among the 29 basins where >20% of forest area burned in a year, streamflow over the first 6 water years postfire increased by a multibasin average of 0.38 SDs, or 30%. Postfire streamflow increases were significant in all four seasons. Historical fire-climate relationships combined with climate model projections suggest that 2021 to 2050 will see repeated years when climate is more fire-conducive than in 2020, the year currently holding the modern record for WUS forest area burned. These findings center on relatively small, minimally managed basins, but our results suggest that burned areas will grow enough over the next 3 decades to enhance streamflow at regional scales. Wildfire is an emerging driver of runoff change that will increasingly alter climate impacts on water supplies and runoff-related risks.

Predicting year class strength for climate-stressed gadid stocks in the Gulf of Alaska

Climate change makes fish stocks more vulnerable to recruitment failure, and early detection of these events is important for an effective management response. Here, we evaluate the value of larval and juvenile surveys, and a thermal spawning habitat index, for predicting recruitment in two economically important gadids, walleye pollock (Gadus chalcogrammus) and Pacific cod (G. macrocephalus), in the Gulf of Alaska. These stocks have been exposed to rapid human-induced ocean warming since 2014, which has apparently contributed to anomalies in age structure, size at age, and other population variables (for pollock) and stock collapse (for cod). We found that warming results in recruitment that falls short of predictions from historical spawner-recruit relationships for both stocks, highlighting that climate change makes recruitment expectations based on historical experience less reliable. However, we also found that recruitment could be successfully predicted with surveys of early-life stages. Using Bayesian regression, we found that juvenile trawl survey data for pollock predicts recruitment to age-1 (as estimated by a stock assessment model), while prediction from larval surveys was less successful. Beach seine estimates of juvenile abundance also predicted pollock recruitment, a surprising result for a species that is typically sampled in offshore habitats. The spawning habitat index and beach seine survey both predicted cod recruitment to age-3 as estimated by the stock assessment model. We did not find a predictive relationship between cod larval abundance and recruitment. However, residuals from the larval model showed low-frequency variability, suggesting nonstationarity (time-dependence) in the predictive relationship. Dynamic Factor Analysis (DFA) models summarizing information across multiple data sets showed reasonable predictive value for both species (Bayesian R2 ≈ 0.4 for log recruitment), and they also allowed recruitment prediction for years with missing observations in some data sets. We conclude that surveying multiple early life stages may be the most useful approach for predicting gadid recruitment.

Complex genetic patterns and distribution limits mediated by native congeners of the worldwide invasive red-eared slider turtle.

Non-native (invasive) species offer a unique opportunity to study the geographical distribution and range limits of species, wherein the evolutionary change driven by interspecific interactions between native and non-native closely related species is a key component. The red-eared slider turtle, Trachemys scripta elegans (TSE), has been introduced and successfully established worldwide. It can coexist with its native congeners T.cataspila, T.venusta and T.taylori in Mexico. We performed comprehensive fieldwork, executed a battery of genetic analyses and applied a novel species distribution modelling approach to evaluate their historical lineage relationships and contemporary population genetic patterns. Our findings support the historical common ancestry between native TSE and non-native (TSEalien ), while also highlighting the genetic differentiation of the exotic lineage. Genetic patterns are associated with their range size/endemism gradient; the microendemic T.taylori showed significant reduced genetic diversity and high differentiation, whereas TSEalien showed the highest diversity and signals of population size expansion. Counter to our expectations, lower naturally occurring distribution overlap and little admixture patterns were found between TSE and its congeners, exhibiting reduced gene flow and clear genetic separation across neighbouring species despite having zones of contact. We demonstrate that these native Trachemys species have distinct climatic niche suitability, probably preventing establishment of and displacement by the TSEalien . Moreover, we found major niche overlap between TSEalien and native species worldwide, supporting our prediction that sites with closer ecological optima to the invasive species have higher establishment risk than those that are closer to the niche-centre of the native species.

Coming full circle: a critical review of the historical changes in governance, nutrition and food security of Labrador Inuit between 1500 and 2005

ABSTRACT Labrador Inuit are an Indigenous People from northern Labrador, within the province of Newfoundland and Labrador, Canada. Prior to European contact, Labrador Inuit were self-reliant. However, historical relationships with Christian missionaries, the Government of Newfoundland and Labrador, and the Government of Canada impacted their relationship with food, access to food, and the physical and social health of Labrador Inuit. This review is based on the stages of colonization. It uses a critical dietetics lens to examine the extrinsic causes of nutrition and food security issues that resulted from colonization, and describes the interventions implemented to address them. Moreover, the review shows the resilience and adaptability of Labrador Inuit as they came full circle from self-sufficient Labrador Inuit in the 1500s, to sign the first Inuit land claim agreement in Canada and form the Nunatsiavut Government in 2005.
