Colony Structure Research Articles

Nurse bees regulate the larval nutrition of developing workers (Apis mellifera) whenfeeding on various pollen types.

Nutrition has been identified as a key driver of colony health and productivity. Yet, in honey bees, relatively little is known about how the vast variety of natural pollen sources impact larval development. The impact of the nutritional quality of 4 naturally occurring pollen sources, of importance to the Western Australian beekeeping industry, was tested on honey bee (Apis mellifera L.) development. Bee packages consisting of 800g of bees and a mated sister queen were assigned to 40 nucleus hives and randomly allocated to one of the 4 feed treatments (10 colonies each) of marri (Corymbia calophylla Lindl.), jarrah (Eucalyptus marginata Sm.), clover (Trifolium repens L.), and canola (Brassica napus L.) pollen. Emerging bees were collected once the first bees started hatching on the assigned feed sources. Newly emerging bees were weighed individually, and body composition was measured in batches according to the feed treatment groups. Food consumption was recorded for the duration of the experiment. Nurse bees successfully raised young adult workers from the larval stage until emergence when fed with one of 4 pollen patties with different nutritional qualities. There was no difference in the body composition or weight of emerging bees fed on the different pollen types. However, the body weight of bees increased over time, most likely related to colony size and structure. With the type of pollen patties having little impact on larval development, the availability of pollen may be more important than its composition, providing bees have access to all essential nutrients.

On solid ground? Manumitted slaves, land ownership and registration in eighteenth-century Sri Lanka

ABSTRACT In pre-industrial societies subsistence agriculture played a crucial role in ensuring survival, not just for people born free, but also for those born into slavery. Within the legal framework of colonial structures, certain owners granted their enslaved individuals temporary usage rights to parcels of land upon their emancipation, and in rare cases, even bestowed permanent ownership. This article wants to study land ownership patterns of manumitted slaves in eighteenth-century Sri Lanka, when the island’s coastal territories were subject to the influence of the Dutch East India Company. By examining Dutch-language last wills from the period 1702 to 1765 we analyze the patterns of land donations by former owners to their freed slaves. By establishing connections between these donations and the detailed land registers of suburban districts surrounding the cities of Colombo and Galle, our objective is to uncover the shortand long-term implications of land ownership for the manumitted individuals and their families. Furthermore, this article also reflects on the implications of negotiated registration practices of such land ownership with a colonial power for the manumitted slaves. What did the label ‘manumitted’ or ‘free’ slave entail in Sri Lanka’s society, and how did registration in Dutch bureaucracy influence those labelling practices?

Variation in Water-Holding Capacity in Sphagnum Species Depends on Both Plant and Colony Structure

Peatlands have become a focal point in climate mitigation strategies as these ecosystems have significant carbon sequestration capacities when healthy but release CO2 and other greenhouse gases when damaged. However, as drought episodes become more frequent and prolonged, organisms key to the functioning of some peatlands are increasingly under pressure from desiccation. The Sphagnum mosses, which tend to keep their ecosystem waterlogged and many of whom promote peat formation, are only mildly desiccation-tolerant in comparison to other mosses. The role of Sphagnum anatomy and colony structure is poorly understood in the context of desiccation resilience. Using four different Sphagnum species belonging to four different subgenera and positions along the gradient of the water table, we show that plant morphological traits and colony density are important determinants of water storage capacity. Our results show that, as previously postulated, the majority of the water is stored in an easily exchangeable form, probably extracellularly, and that plant morphological traits, specifically the type and presence of branches, are major contributors to water storage and can explain some of the interspecies variation. We also show that plant density is another important determinant for water storage capacity as higher densities hold larger quantities of water per unit of biomass for all four species, which increases resilience to desiccation. The results presented here suggest that species choice and planting density should receive more attention when considering peatland restoration strategies.

One Territory, Two Worlds

This paper analyzes Kazuo Ishiguro’s When We Were Orphans is a literary work that critiques and examines colonial structures and their consequences: Ishiguro criticizes the colonization of Shanghai by showing the inherent power imbalance between the native population and the colonizers, the chaos and lawlessness outside of the Settlement as opposed to within, and the general understanding of Shanghai and the Settlement held by characters from Britain. As a work of historical fiction, the novel serves to explore a particular society at a particular point in time, and therefore, must be analyzed with close consideration to the historical period and context in which the novel is set. At the same time, this paper concludes, Ishiguro’s observations and critiques are highly relevant in today’s society.
  

Towards unsettling the racial nation-state: affective interventions in an Australian literature classroom

ABSTRACT As the adoption of the Immigration Restriction Act 1901 (otherwise known as the White Australia policy) reveals, whiteness has always been fundamental to the Australian nation-state. White sovereignty is constitutive of the Australian nation, making it a racial state. But the devastating impact of whiteness on those deemed ‘not-white’ remains largely unacknowledged. Drawing on framing of affective economies and an empirical study tracing how secondary school students in a Literature class negotiate their identities amidst structures of colonialism, I explore the affective dynamics of these negotiations with attention to how emotions align some bodies with particular communities and situate some outside of nation. Within a pedagogic intervention aiming to disrupt canonical assumptions, I collected written responses, recorded group discussions from all class members, and interviewed a selection of these students. Data analysis demonstrates that many in the class were oriented to whiteness as ‘Australianness’ at the expense of other possible cultural identities offered by their biographies, often resulting in emotions of shame or disorientation. It invites us to think beyond national borders to avert the deleterious effects ‘nation-ness’ can have on those it excludes and to work towards implementing pedagogic interventions that might unsettle the racial nation-state.

Fuel Smuggling in the West Bank (2018–2021): Palestinian Economic Agency under the Israeli System of Spatial Control

This article critically re-examines the narrative that the Israeli system of spatial control has an exclusive negative impact on the West Bank economy. It focuses on the burgeoning fuel smuggling industry, which grew to constitute nearly one-third of the total consumed fuel in the West Bank by 2018. The article posits that the impacts of Israeli control on West Bank-Israeli economic relations involve an interplay between structural top-down imposition and Palestinian agency exerted from below. Drawing from documentary evidence and semi-structured interviews conducted with smugglers, Israeli, and Palestinian policymakers, the research reveals a paradox, finding its theoretical explanation in borderland studies. The barriers and fragmentation meant to oppress Palestinians create opportunities for new Palestinian economic beneficiaries. The article traces the emergence of smuggling networks that expand Palestinian-Israeli connections and cooperation. It concludes considering how the structure-agency interplay, which characterizes the Israeli colonial structure, affects the study of Palestinian political economy under Israeli occupation. This includes the influence of smuggling on supply, demand, pricing, and power hierarchies within the West Bank’s fuel sector.

Building an ethical research culture: Scholars of refugee background researching refugee-related issues

Abstract Recent scholarship on the need to decolonize refugee research, and migration research more generally, points to the urgency of challenging ongoing colonial power structures inherent in such research. Increased involvement of scholars with lived experience is one way to challenge and remake unequal and colonial power relations. Through discussions with researchers of forced migration, we aimed to explore the challenges, barriers, and supports related to involvement in such research, and to identify how research practices and structures could be improved to increase and facilitate the involvement of scholars with refugee backgrounds. In this field reflection, we highlight key points and suggestions for better research practice that emerged from these discussions. In doing so, we are endeavouring to contribute to the important ongoing conversation about ethics and decolonizing research. We build on existing ethical guidelines by opening up some of the complexities of ethical practice and offering concrete actions that can be taken to work through these.

Whiteness and Bodies Out of Place: A Critical Discussion of Early Childhood Educators’ Regulatory Language Practice in a Danish Context

This article sheds light on contemporary interconnections between colonialism, whiteness and notions of Danishness. It offers a critical perspective on the possible (side) effects of emphasising Danish language proficiency in everyday pedagogical encounters with racial-ethnic minoritised children. Taking on the notion of coloniality of power (Quijano, 2000), the article considers Denmark’s colonial complicity and its present implications in today’s social structures and, in particular, in Early Childhood Education and Care (ECEC). The article is based on critical ethnographic fieldwork (Madison, 2020) conducted in a Danish ECEC centre. By theorising whiteness (Ahmed, 2007) in relation to ideals of Danish language proficiency and by drawing on postcolonial theory (Fanon, 1952/2021, 1967), the article investigates how a regulatory language practice performed by ECEC educators can be understood as normative whiteness affecting a group of three 4–6-year-old racial-ethnic minoritised children with Turkish backgrounds. The analyses show how the children navigate the white space of the ECEC centre by adjusting their bodies accordingly as they are rendered bodies out of place. Conclusively, the article points to Danish ECEC institutions as critical sites in the reproduction of colonial power structures.

Education and Coloniality in the Nordics

Current research maintains that the Nordic countries, despite their contextual differences, are prone to amnesia and sanctioned ignorance in relation to their colonial histories, legacies, and structures (Eriksen, 2021; Fjellheim, 2023; Höglund & Andersson, 2019; Jore, 2022; Keskinen et al., 2019; Kuokkanen, 2023; Loftsdóttir & Jensen, 2012; Mikander, 2016; Pashby et al., 2020. As Quijano (2000) describes, European colonialism from the 15th century did not end with historical colonialism based on territorial occupation; enduring power and knowledge structures were installed in and through modernity, described as coloniality. Coloniality entails a specific colonial matrix of power (CMP), grounded in race as an organizing principle. CMP permeates social, political, environmental, and epistemological systems of capitalist modernity in local and context-specific ways. This special issue (SI) aims to advance critical discussions about coloniality in relation to education in the Nordic region. Education has been proven to reproduce coloniality, epistemic violence and racism, but represents at the same time potential avenues towards decolonial, socially just and sustainable futures. A decolonial conversation must give room for a diversity of voices. This is due, not least, to the harsh pushbacks experienced by researchers who raise these concerns in the Nordic context. As scholars, we see worrying signs emerging from the consequences of mainstreaming of radical right-wing politics. These include cuts to welfare and development aid and limiting rights for refugees – all aspects which have commonly been seen as intrinsic to Nordic national identities. The recent case of Tobias Hübinette, a scholar in critical race and whiteness studies, is an alarming example of how academics are being threatened. A supporter of the radical right wing enrolled in his class recorded and disrupted the lecture, attempting to silence Hübinette’s research on questions about racism in general. Despite the student being a threat to university staff and students, they were not expelled (Norheim et al., 2023). The case highlights the need for joining forces and making space for conversations across the Nordic community of researchers engaged in the issues of race, racism, whiteness, and coloniality. The first articles in this SI were written by Jore and Fagerheim Kalsås, and open with theoretical discussions concerning approaches to coloniality in Nordic education. The following contributions show the richness of the field, taking on a diversity of approaches, including poststructuralist and critical whiteness theories, post- and decolonial perspectives, and indigenous methodologies, as well as more empirically oriented and descriptive pieces. Although these methodological strands have many overlaps and are in practice often combined in research, they are also at certain points conflicting (cf. Eriksen & Jore, 2023; Finbog, 2023; Groglopo & Suarez-Krabbe, 2023; Keskitalo & Olsen, 2021). We do, however, consider diversity as a strength. Coloniality is complex and can be considered a foundational concept that encompasses many distinct processes and structures at multiple levels (Kuokkanen, 2023). With this editorial, the aim is to provide background knowledge and an axis of navigation for the articles in this SI. We start with a brief recap on the multiple ways in which colonialism, racial violence, and white supremacy form part of the history of the Nordic countries. As this overview shows, decolonial perspectives have been surprisingly belated in the region. We then give a brief introduction to education and decolonization in the Nordic region – a subject that is much better explored in the individual contributions. Then, finally, we draw special attention to acknowledging indigenous perspectives in analyzing decoloniality in the Nordic region and intra-Nordic relations.

Agency is Positionally Distributed: Practice Theory and (Post)Colonial Structures

Abstract Why are some practices available to some actors in world politics, but not to others? In this theory note, we develop a theory of agency as positionally distributed: In global politics, the action potentials of groups and individuals vary depending on their location in the macrostructures inherited from common histories of colonial domination and exploitation. We contribute to the understanding of subordinate agency by exploiting the many synergies between International Practice Theory and Postcolonial Theory. Where the former sometimes struggles to capture deep macrostructures, the latter emphasizes the constitutive effects of coloniality. Conversely, where the postcolonial gaze faces the aporia of giving voice to the subordinate, a practice approach helps make sense of the indexicality of agency, including defiance and subversion. Based on these complementarities, we develop a structural concept according to which agency, including subordinate forms, is a relational effect of an unequal playing field characterized by centuries of (post)colonial dynamics. Overall, the theory note helps explain why the very same practices, such as border crossing, seem to be distributed unequally across groups depending not on their competence but on their position in social and international structures such as the North–South divide or the global color line.

A case for the abolition of “terrorism” and its industry

ABSTRACT Amidst a decolonial turn, the question of how to study “terrorism”, a concept deeply entrenched in racial, gendered, and colonial structures, becomes increasingly imperative. Whilst calls for developing a “Decolonial Terrorism Studies” have already been made, I argue that a truly decolonial approach towards the study of terrorism needs to reject such a call and instead acknowledge the irredeemability of “terrorism” as a legitimate category of political violence. As I argue here, Critical Terrorism Studies (CTS) needs to engage with decolonial approaches if it wants to continue constituting the counter hegemonic challenge to Terrorism Studies it set out to provide upon its inception. However, calling for a “decolonisation” of the discipline is contradicting such an approach and, as I argue, rooted in the assumption that the category “terrorism” can be reclaimed. I call instead for its abolition. “Terrorism” needs to be acknowledged as a construct that carries racial, gendered, and colonial implications and assumptions whose utterance alone constitutes a form of violence which always perpetuates those implications. Thus, the purpose of CTS, especially if it is to adopt decolonial approaches, should be to interrogate in what ways the concept “terrorism” functions to work for the project of Western colonial-modernity. It should not be how (Critical) Terrorism Studies can rebrand as “decolonial”. Following from this, the ultimate goal for CTS scholars should be to contribute to the abolition of “terrorism” as a term and Terrorism Studies and its industry as a whole.

Bleeding Forms: Beyond the Intifada

Abstract This essay considers the war in Gaza from the perspective of resistance as an anti-concept. It draws inspiration from the notion of the informe (formless) as described by Georges Bataille to understand how resistance acts as a formless operation that deforms the colonial structure. It argues that resistance overflows the condition it seeks to dismantle and bring down in the world. The paper explores the difference between Bataille's account of the operation of the formless and Frantz Fanon's understanding of the "tabula rasa," highlighting how resistance can break down, deform, and distort following this capacity to deform historically. However, the Palestinian resistance did not achieve the radical break, or what Frantz Fanon describes as the minimum demand of the colonized, the clean slate from which a genuine decolonization can ensue. The essay explores how the Palestinian resistance initiated on October 7 a meticulously orchestrated offensive maneuver that surpassed the spontaneous uprisings of previous intifadas. It was a calculated decision to deform the existing order. The essay points to the novel development in Palestinian resistance where the decision to instigate this process of decomposition has become wedded to a decider and a locus, while highlighting some of the pitfalls of this development. It argues that the current moment is marked by a decomposition of the colonial order without decolonization.

Entangled engagements: a posthumanist and affirmative ethics for tourism geographies

This review summarizes some key moments in the development of ethics in tourism research and practice where three main areas of concern are identified: socio-economic inequalities, cultural discriminations, and more-than-human speciesism. Following a brief historical review, the paper delves into some current trends and ethical concerns in tourism geographies, which trace back to the utilitarian ethics within which contemporary tourism emerged, after which, and with the growing concerns about tourism’s negative impacts, normative and moral approaches to ethics held sway. Then the paper addresses a critical gap in tourism ethics’ research and practice. With few exceptions, tourism environments are seen as something apart, things to be managed, developed or even protected, where the focus is instrumental on how these environments can be maintained or manipulated for human benefit. This modernization paradigm and its promise of progress through growth, together with a tourism industry that (re)produces colonial structures through neocolonial practices reinforced by neoliberal globalization has contributed to a host of present-day challenges and injustices. We argue that to address the injustices above and current existential crises like climate change, and other threats to socio-ecological well-being, a paradigm shift in tourism thinking is needed. Specifically, we propose embracing posthumanist ethics as a novel, experimental (as against normative or moral), situated (as against universal), and affirmative (as against oppositional) critique of structural injustices and structural power; epistemological pluralism (as against essentialism), acknowledging the relationality proper of indigenous cosmologies and other traditional knowledges (where more involvement from the Global South is needed); and a new materialist ontology that overcomes human exceptionalism and abandons oppositional binary thinking. In other words, what is needed, is an affirmative posthumanist ethics for tourism that is relational, plural and differential.

Ecofeminism ↔ Intraconnectivism: working beyond binaries in environmental education

ABSTRACT Over the last decades, ecofeminist thought has moved into a ‘fourth stage critical ecofeminism’ (Gaard 2017, xvi), based on an understanding that humans are unavoidably part of a multifaceted and interconnected global ecosystem. This paper suggests that ecofeminist theory and practice can now grow further into a fifth stage: an era of expanded intersectionality that moves beyond the dualisms and hegemonies of neo-liberal patriarchal and colonial capitalist structures that can limit ecofeminist theorizing and material practice. This fifth stage must be based on an amalgamation of engaged theory, education, and activism, grounded in ancient wisdom and with the understanding that all material-discursive phenomena are interconnected. For this next era of ecofeminism, the terms intraconnectivism and intraconnective education (Siegel 2022) are proposed. Intraconnectivism offers a bridge that connects past theoretical frameworks with ecofeminist presents. It can build a helpful theoretical pathway through and amongst the non-dualistic educational pedagogies that are needed at this time, as well as expand understanding of the role that gender and other identities can play in education.

Indigenous Internationalism Against Imprisoned Indigeneity in Australia and Palestine

Indigenous Australians and Palestinians experience some of the highest rates of incarceration and state violence in the world. In this article’s first section we focus comparatively on administrative detention and other forms of incarceration to underline a commonality of oppression that is both historical and contemporary. We examine settler colonial structures of domination and the impact of structural violence on Indigenous bodies, seeking to understand how incarceration acts as a form of elimination, and how it contributes to the consolidation of settler colonial nationhood. To counter incarceration and elimination, this article’s second and third sections call for a politics of solidarity premised on shared indigeneity.

Microstructure evolution and mechanical property of melt-grown Al2O3/GdAlO3/ZrO2 eutectic ceramics prepared by laser directed energy deposition

Highly dense Al2O3/GdAlO3/ZrO2 eutectic ceramics are one-step additively manufactured by laser directed energy deposition technique under different scanning speed to investigate the inherent response relationship between processing parameter, microstructure, and mechanical property. During the layer-wise deposition process, planar-cellular transition occurs near the bottom of the molten pool, leading to the transformation of irregular eutectic structure into eutectic colony structure lengthened along the building direction, accompanied by the refinement of microstructure dimension. With the increase of scanning speed, the eutectic spacing decreases, and the initially irregular “Chinese script” eutectic ultimately transforms into hexagonally arranged rod-like eutectic structure induced by lamellar instability. The rod spacing is 1.136 times larger than the lamellar spacing. The mechanical property of the laser 3D-printed Al2O3/GdAlO3/ZrO2 eutectic ceramic is manifested as isotropic. The hardness increases with the refinement of the microstructure, while the fracture toughness decreases as the eutectic morphology transforms into rod-like structure. The averaged hardness and fracture toughness are 16.27 GPa and 3.39 MPa‧m1/2, respectively.

Experiential Extractivism in Service-Learning and Community Engagement

Extractivism is so often characterized as resource extractivism – the exploitation of a community’s natural resources for economic gain. However, when we think about the relationships between community and university, there are many ways in which the university can take out of the community or benefit to an extent that extracts human, capital, and natural resources. I contend that some of the university-community engagement work that has been done in the last 20 years replicates colonial structures in ways that have harmed communities under the well-intentioned guise of service-learning, community-based learning, or “development.” Drawing on Du Bois (1947) and on Riofrancos’ (2020) work on colonialism and extractivism, this paper will explore the role of the university as both a transformer and oppressor through global learning. I will explore the promise and pitfalls for these engaged pedagogies, and propose pathways to avoiding unjust, extractive practices in the pursuit of learning and student development. I will end with recommendations for just, equitable, and critical community-based global learning and some promising examples.

Potential biomarkers of acute myocardial infarction based on the composition of the blood microbiome

BackgroundIt is difficult to distinguish between acute myocardial infarction (AMI) and unstable angina (UA) due to their similar clinical features. In recent years, studies have shown that microbiomes have great potential in distinguishing diseases. The purpose of this study is to describe the composition of serum microbiome in the AMI and UA by 16S rDNA sequencing. MethodsBased on the high-throughput detection platform and 16S rDNA amplification sequencing technology, this study detected the blood microbial composition of 55 patients with AMI and 62 patients with UA. Alpha diversity and Beta diversity analysis were used to compare the differences in microbial composition and bacterial colony structure between AMI and UA groups. We perform PCoA (Principal Co-ordinates Analysis) based on Unweighted Unifrac distance. In addition, various statistical methods were employed to examine the significance of differences in microbial composition and genus between the two groups. PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States) was employed to predict KEGG (Kyoto Encyclopedia of Genes and Genomes) function from 16S sequencing data. Random forest was applied to identify biomarkers and construct the diagnostic model. Subsequently, the stability of the model was verified by 10-fold cross and the diagnostic effectiveness was evaluated through ROC (Receiver Operating Characteristic). ResultsIn this study, we found that alpha diversity index of serum microbiome in AMI group was significantly higher than in UA group. T-test analysis demonstrated that the UA group presented a higher abundance of Ralstonia, Faecalibaculum and Gammaproteobacteria, while Bacteroides, Sphingomonas, Faecalibaculum, Haemophilus, Serratia, Bifidobacterium and Chloroplast were more abundant in the AMI group. The LefSe (LDA Effect Size) analysis showed that the Gammaproteobacteria, Proteobacteria, Ralstonia pickettli, Ralstonia, Burkholderiaceae and Burkholderiales were enriched in UA group, and Bacteroidales, Bacteroidia, Bacteroidota, Clostridia and Firmicutes were more abundant in the AMI group. Ten bacterial diagnostic models were constructed in the random forest. The area under the curve (AUC) in the training set was 88.01%, and the AUC value in the test set was 95.04%. ConclusionIn this study, the composition of blood microorganisms in the groups of patients with AMI and UA has been analyzed, providing novel insights for understanding the pathogenesis of AMI; Blood microbiome may serve as novel diagnostic biomarkers of AMI.

An Abolitionist Liveability Against State Carceral Unchilding Ahmad Manasra’s life-making

This article will not look at the incarceration of Ahmad Manasra through the prism of state violence against him, but more specifically through his radical call for “life-making”—as an abolitionist liveability against state criminality. We join Ahmad in taking a critical stance towards the politics of life—and what Aysha Odeh and Robin Kelley refer to as “freedom dreams”—refuting the state’s carceral network and the acceptance of the settler colonial necropolitical structure. In doing so, the article conceptualizes Ahmad Manasra’s multiple modes of refusal as acts of defiance against the brutality of state “unchilding,” arguing that his unending search for freedom are radical abolitionist cries that cannot be overlooked.

Infrastructural Development and Neo-Colonialism in Africa: The Case of the Standard Gauge Railway in Kenya

Abstract The paper argues that funding and development of mega projects in Africa is the new way through which neo-colonialism is manifesting itself. Development partners are increasingly using infrastructural development aid as the means to continue exploiting and dominating Africa’s political economy. Using the Chinese funded Standard Gauge Railway in Kenya as a case study, the paper confirms that to some extent infrastructural development projects are replicating colonial structures. The role of foreign funding, multinational corporations, and co-option of elites provides neo-colonial anxieties. However, through sensitivity to Africa’s mounting external debt, and its policy on shared prosperity, China demonstrates that not all its activities on the continent have neo-colonial characteristics. It renegotiates loan repayment, converts loans to grants, and withholds loans to assessed recipient’s abilities to repay. The concept of neo-colonialism provides a framework through which to analyze externally funded development projects in Africa. The study analyzed secondary sources of data.
