Introduction: Closures—Ocean Governance Borders
Authors: Peters Kimberley , Turner Jennifer 
Published: February 2025

Abstract
This chapter provides an introduction to the book ‘Ocean Governance (Beyond) Borders’, a text that that shifts across varying oceanic terrains to offer, in one collection, a sustained reflection on bordering and oceans, written by those central to researching and reflecting on such debates. The chapter reviews some of the longstanding literature on borders, boundaries and enclosures from across different disciplines, including human geography and international relations, before examining such ideas in the particular context of the seas and oceans. It provides a backdrop to the ways borders are planned, enacted, monitored and enforced but also the ways in which they are porous, leaky, subject to change, transgressed and contested, all in a largely mobile medium—the seas and oceans—that are ever resistant to bordering. The chapter offers a discussion of (en)closures as a means of opening up debates central to the book, to introduce the key themes that weave through the chapters, as well as briefly summarizing the chapters that comprise the collection. The chapter ends with ideas to frame readers’ engagement with the book, and some thoughts on how the contributions herein might be navigated.
Infrastructural Containment and the Politics of Migration in the Mediterranean Sea
Authors: Şarlak Lara 
Published: February 2025

Abstract
This chapter questions how European nation-states develop maritime border securitisation strategies that are contingent on the ontology and materiality of terrain on which those borders are established. To do so, it uses ‘infrastructures’ as an analytical tool and explores how oceanic materialities are part of the complexity of migration in/at the Mediterranean Sea, raising questions on how seascapes are transformed into sites of control and conflict. It introduces the concept infrastructural containment to address the spatio-material strategies deployed by nation-states to further strengthen borders and contain ‘clandestine’ maritime crossings. The chapter questions how containment of migrant mobilities is configured through the fluid, vast and turbulent nature of the ocean and how its often hostile terrain plays an active role in the production of border infrastructures by becoming an environmental boundary. It argues that an infrastructural approach to water allows for additional ways of understanding technologies of containment at the Mediterranean Sea and the challenges posed by the ocean’s wetness and fluidity resists also the EU’s attempts to establish rigid territorial boundaries. This chapter underscores the complex and evolving nature of maritime borders, prompting a critical reflection on oceanic governance, which often relies on land-centric approaches to territorialisation.
Overdetermined by Territory? Governing the Ocean in Time, Matter, and Rhythm
Authors: McAteer Christopher 
Published: February 2025

Abstract
This chapter asks whether thinking about space goes far enough in comprehending the ocean, arguing that scholars must engage more with materiality and temporality to discover new forms of ocean governance. Noting the important scholarly work that has moved beyond a planar, or areal, conceptualisation of the ocean, the chapter draws on recent scholarship to critically assess volumetric theorisations that do not sufficiently account for the fluidity of matter within the ocean. It contends that scholars must think through the complex materiality of the ocean by conceptualising the highly mobile stuff within it as being an inherent part of ocean space itself. It then argues that to think about the materiality of the ocean and how it moves and flows, one must engage with temporality, helping one to move beyond both two-dimensional thinking and three-dimensional volumetrics towards an understanding of the ocean as processual and something that happens in time. Surveying recent literature on relational approaches to space, the chapter argues that the future of ocean governance must be multiple, complex, and messy, rather than overdetermined by a political logic of territory that reifies state borders as a byproduct of its legal mechanisms.
Bordered-In, Bordered-Out, and Overlapping Territorialities in Ocean Space: The Case of Fisheries
Authors: Hung Po-Yi 
Published: February 2025

Abstract
This chapter draws from the example of fisheries to unpack the politics of ocean borders in relation to both resource extraction and environmental protection and in view of state territoriality. The first section bordered-in territoriality focuses on fisheries and conservation within the territorial seas and EEZs, where ocean borders are associated with state’s sovereign rights. Second, it takes the space of high seas as the bordered-out territoriality, emphasising the high seas as the commons and the ways the state performs its territoriality without claiming sovereign rights via distant-water fisheries. Third, overlapped territoriality is used to address the disputed maritime grey zones between different states and how fisheries have played a key role in bordering-up a cooperative space of sovereign rights for fishing. Although this chapter focuses on discussions about fisheries, the critical points addressed actually extend beyond this activity and connect to debates regarding other marine resources in general.
Contested Borders and Resolution in Planning Shared Marine Waters
Authors: Ansong Joseph Onwona 
Published: February 2025

Abstract
This chapter explores how practices of Marine Spatial Planning (MSP) factor in contested national borders. It argues that, although the resolution of contested national borders in marine space is not a planning competence, MSP must contend with its impact and related resource conflicts. This chapter asks: how are jurisdictional issues around borders considered in MSP and can MSP address spatial conflicts in contested marine areas? It examines two contested case study areas on Island of Ireland and the Pomeranian Bay (Germany and Poland) to understand how the history of contested borders has evolved and its contribution to contemporary marine management issues. The chapter then reviews existing marine legislation, policies, and marine spatial plans to understand how contested borders and areas are deliberated in MSP. This chapter argues that the effectiveness of MSP in contested areas remains ‘a planners dream’ that is not achievable due to geopolitical problems and historical legacy disputes that emanate from border issues. Progressive cross-border MSP requires capacity to align governance arrangements, a nested collaborative framework, and enhance the role of bridging organisations.
Can Borders in the Ocean Respond to Climate Change?
Authors: Kunz Yvonne 
Published: February 2025

Abstract
This chapter discusses whether and how climate change as a global challenge and discourse is related to the role of oftentimes-static conservation logics in marine protection. Based on an interdisciplinary, multi-sited project, the chapter explores the role climate change plays in Marine Protected Area (MPA) governance. Marine Protected Areas (MPAs) are, bluntly speaking, nothing but lines drawn on an ocean map. The viability of MPAs in terms of achieving long-term conservation of nature with associated ecosystem services within and beyond these lines, is debated. While under debate, there is an immense push to increase the number and size of protected areas in the oceans. Drawing on experiences from MPAs of differing ages in the Dutch Caribbean, demarcation and delimitation dynamics are explored: how are conservation boundaries informed and designed and what do they mean to human and non-human entities. It does so to critically discuss the place of bordering in the repertoire of ocean governance approaches in the context of climatic change. Unpacking these challenges, even without climate change as additional stressor, makes the push for more protected areas seem a hasty next step.
Bordering Marine Belonging: The Meanings, Mobilities and Materialities of Bioinvasion
Authors: Savitzky Satya , Peters Kimberley , Sammler Katherine G. 
Published: February 2025

Abstract
This chapter focuses on the relationship between borders and belonging in marine worlds, paying special attention to debates concerning marine invasive species. Within a number of natural and social science disciplines, studies of invasive species are both long-established and continuing to grow and change. Major research into marine ‘invasions’ has come later than terrestrial studies, so critical social scholarship in invasive species (or bioinvasion) remain largely (though not exclusively) landlocked. Where studies are watery, they are of fresh, rather than salt water and ‘interior’ rather than focusing on ‘exterior’ liquid zones. This chapter has two aims. It firstly identifies invasive species as a topical issue that is marginal in critical discussions of ocean bordering/belonging. It secondly puts forwards three ways in which bioinvasion, bordering and belonging can be better understood, through (1) questions of definition and meaning; (2) an attention to the mobilities and materialities enrolled within processes of bioinvasion—the movement of marine species in global circuits; and (3) how borders are enacted in view of invasive species via biosecurity measures. The chapter aims to disrupt conventional narratives of marine belonging, showing a biological world that is ‘stitched’ together.
Human-Shark Encounters Beyond Borders: (Post-humanist) Attempts to Navigate a Maritime Contact Zone
Authors: Verne Julia 
Published: February 2025

Abstract
In recent years, human-shark encounters in the Indian Ocean have sparked highly controversial debates over humans’ right to the sea. While sharks pose a danger to humans that some wish to eliminate, at the same time, they are endangered themselves and demand protection as a crucial part of marine ecosystems. Hence, in an attempt to solve this conflict of interest, different technologies are currently developed and used to mediate human-shark encounters. While some technologies still aim at a clear separation between humans and sharks and thus focus on bordering the ocean, others, however, rather strive for a joint, yet less risky use of space. Taking the different technological innovations in use in the coastal waters of La Réunion as an example, this chapter examines the implications of these technologies for both humans and sharks, as well as for the relation between humans and the sea in this maritime contact zone. In asking whether these socio-technical interventions can be productively interpreted in light of post-humanist calls for more convivial relationships, this chapter contributes to current theoretical reflections on the relation between humans, technologies and the sea and their potential for less anthropocentric maritime spatial orderings.
Paleoseismology and Paleogeodesy Using Coral Microatolls
Authors: Philibosian Belle 
Published: February 2025

Abstract
Establishing the rupture extent and slip distribution of individual paleo-earthquakes is vital for assessing fault behavior including the persistence of rupture segmentation, recurrence patterns, and similarity of successive events, key issues in both fault mechanics and hazard assessment. Techniques with high temporal and geodetic precision as well as a wide distribution of study sites are necessary to investigate past earthquakes in such detail. Coral microatoll growth is one of the best types of geologic record for paleoseismology and paleogeodesy given these needs, as it provides long, continuous, widely distributed records of centimeter-scale vertical tectonic motion with potentially annual-level temporal precision. This chapter describes the process of interpreting microatoll growth records to obtain time series of relative sea level, tectonic vertical deformation fields, and finally slip and coupling parameters on an underlying fault interface.
Gesundheitskompetenz und Gesundheitsverhalten – Einblicke in ein sich ausdifferenzierendes Forschungs- und Handlungsfeld für Public Health
Authors: Jordan Susanne , Buchmann Maike , Loss Julika , Okan Orkan 
Published: February 2025

Zusammenfassung
Das Forschungs- und Handlungsfeld „Gesundheitskompetenz und Gesundheitsverhalten“ differenziert sich zunehmend aus. Allgemeine Gesundheitskompetenz (aGK) ist etabliert, mit dem Fokus auf bevölkerungsweite Studien. Spezifische Gesundheitskompetenzen (sGK) zum Gesundheitsverhalten bieten themenbezogene Ansatzpunkte für Interventionen und Public-Health-Strategien.
Für die aGK und auch sGK aus den Bereichen Ernährung und Bewegung/körperliche Aktivität gibt es verschiedene Konzepte, Definitionen und Messinstrumente, die sich in Bezug auf die Handlungsebenen und Anwendungsbereiche der Gesundheitskompetenz unterscheiden.
Die meisten Studien zeigen eine positive Assoziation zwischen Gesundheitskompetenz (GK) und verschiedenen Gesundheitsverhalten. Eine höhere GK geht häufiger mit einem verbesserten gesundheitsförderlichen Verhalten einher. Dies gilt für die aGK wie auch für die sGK zur Ernährung und Bewegung. In einigen Studien wurde für bestimmte Verhaltensweisen kein Zusammenhang gefunden, in anderen nur für bestimmte Gruppen, was auch auf die unterschiedlichen Messinstrumente und Untersuchungskontexte zurückzuführen sein kann. Dies verweist auf die Bedeutung, stets auch die Wechselwirkung von Verhalten und Verhältnissen zu betrachten, um die Passung zwischen Individuum und den alltäglichen Anforderungen beim Umgang mit Gesundheitsinformationen zu verbessern.
Der Ansatz der „Behavioural and Cultural Insights“ (BCI) kann Erkenntnisse zur Förderung der GK im Hinblick auf verschiedene Gesundheitsverhalten liefern, zu individuellen Barrieren und Förderfaktoren, die sich aus Lebenslagen und Rahmenbedingungen ergeben und die soziale Praxis berücksichtigen. BCI und GK ergänzen sich und haben das Potenzial, Strategien zur Verbesserung des Gesundheitsverhaltens effektiver und zielgerichteter zu gestalten.

Abstract

Background
Firearms are the primary method by which US military personnel die by suicide, and those at highest risk tend to store firearms unsafely. Promoting secure firearm storage practices is a major component of the Department of Defense’s suicide prevention strategy, but perceptions about firearms being associated with suicide risk may impact such efforts.

Purpose
This study examined perceptions that (1) firearm ownership and (2) storage practices are associated with suicide risk and whether key sociopsychological factors (e.g., entrapment, threat perceptions, honor ideology) were associated with these beliefs in a sample of Active Duty (AD) enlisted Army personnel. We then examined if associations varied as a function of firearm ownership or a lifetime history of suicidal thoughts and/or behaviors (STBs).

Methods
Survey data about sociopsychological factors and ownership-suicide risk beliefs and storage-suicide risk beliefs were collected from 399 AD Army personnel. Multiple regression and multigroup path analyses were used.

Results
Greater intolerance of uncertainty and entrapment, and weaker honor ideology, were associated with greater ownership-suicide risk beliefs, whereas being a parent of a minor child was linked with weaker ownership-suicide risk beliefs. None of the variables examined were associated with storage-suicide risk beliefs. Participants with a lifetime history of STBs who had higher threat perceptions endorsed weaker ownership-suicide risk beliefs.

Conclusions
AD Army personnel may tend to believe that firearm ownership and storage practices are largely unrelated to suicide risk. More tailored messaging and suicide-gun violence prevention efforts are likely needed. Findings have important implications for military suicide prevention efforts.
Density-based hole seeding in XFEM level-set topology optimization of fluid problems
Authors: Høghøj Lukas C. , Andreasen Casper Schousboe , Maute Kurt 
Published: February 2025

Abstract
The optimization results of level-set methods typically suffer from a strong dependence on the initial design. To mitigate this dependence, this work presents a density-based hole nucleation method for level-set topology optimization of flow problems. This is achieved by defining both the level-set and density values as functions of the design variables. To preserve the crispness of the geometry definition afforded by the level-set method, the fluid flow is modeled using the Heaviside enriched eXtended Finite Element Method (XFEM) for the laminar incompressible Navier–Stokes equation, which is augmented by a Brinkman model. The boundary conditions are enforced weakly using Nitsche’s method. A face-oriented ghost stabilization scheme is applied to stabilize the XFEM formulation. Additional terms ensuring stability are added to Nitsche’s method and the ghost stabilization to account for the Brinkman term in the Navier–Stokes equation. The necessity of adding these terms is highlighted by numerical studies. Two- and three-dimensional fluid manifolds are optimized to minimize fluid power dissipation while achieving a predefined mass flow distribution among the outlets. The optimization results show that the proposed method bypasses the need for an initial hole seeding and speeds up the convergence of the optimization process.

Abstract
In Alzheimer’s disease (AD), microglia form distinct cellular aggregates that play critical roles in disease progression, including Aβ plaque-associated microglia (PaM) and the newly identified coffin-like microglia (CoM). PaM are closely associated with amyloid-β (Aβ) plaques, while CoM are enriched in the pyramidal layer of the CA2/CA1 hippocampal subfields, where they frequently engulf neurons and associate with tau-positive tangles and phosphorylated α-synuclein. To elucidate the role of these microglial subtypes, we employed high-content neuropathology, integrating Deep Spatial Profiling (DSP), multiplex chromogenic immunohistochemistry and confocal microscopy, to comprehensively map and characterise their morphological and molecular signatures, as well as their neuropathological and astrocytic microenvironments, in AD and control post-mortem samples. PaM and PaM-associated astrocytes exhibited signatures related to complement system pathways, ErbB signalling, and metabolic and neurodegenerative processes. In contrast, CoM displayed markers associated with protein degradation and immune signalling pathways, including STING, TGF-β, and NF-κB. While no direct association between CD8 + T cells and either microglial type was observed, CD163 + perivascular macrophages were frequently incorporated into PaM. These findings provide novel insights into the heterogeneity of microglial responses, in particular their distinct interactions with astrocytes and infiltrating immune cells, and shed light on specific neurodegenerative hotspots and their implications for hippocampal deterioration in AD.

Abstract

Introduction
Intracranial germinoma has a favorable prognosis with modern therapies, but the long-term outcome of cerebrospinal fluid (CSF) diversion for its associated hydrocephalus has been rarely focused on.

Purpose
To evaluate the long-term success of CSF diversion methods—endoscopic third ventriculostomy (ETV) versus ventriculoperitoneal (VP) shunt—in intracranial germinoma patients.

Methods
Only pure intracranial germinomas with obstructive hydrocephalus and a minimum follow-up duration of 24 months were retrospectively reviewed. Their demographics, as well as pre-and postoperative data, were recorded. Patients were stratified into the ETV and the non-ETV groups and subsequently compared to determine the longevity and morbidity related to the procedures. Factors associated with the failure of CSF diversion were examined.

Results
From 1993 to 2022, eighty-three pathologically confirmed intracranial germinomas were identified. Excluding four cases of mixed pathology, eight with incomplete data, and two with insufficient follow-up, we enrolled 69 eligible patients for analysis. Among them, forty-three cases with obstructive hydrocephalus were classified into the ETV (n = 22) and non-ETV (n = 21) groups. No intraoperative or immediate postoperative complications occurred. With a median follow-up of 101 months (IQR 77.75–139.75), the ETV group had no failures. In the non-ETV cohort (median follow-up 144 months (IQR 97–210)), two VP shunt cases (9.5%) required revision due to blockage, and two patients (9.5%) experienced transient over-drainage. These 4 patients were without long-term difficulty despite short-term cumbersome events. No significant factors predicting CSF diversion failure were identified. To date, all 43 patients are alive without metastases, maintaining a good quality of life.

Conclusion
This study highlights ETV as a preferred CSF diversion method in pure intracranial germinoma, achieving 100% success without morbidity. Apart from simultaneous biopsy, avoiding a separate operation, this approach eliminates shunt-related complications, ensuring long-term quality of life in patients with extraordinary prognoses from modern chemo- and radiotherapy.
