- The International Federation of Clinical Chemistry Committee on Clinical Application of Cardiac Bio-Markers provides evidence-based educational documents to facilitate uniform interpretation and utilization of cardiac biomarkers in clinical laboratories and practice. The committee's goals are to improve the understanding of certain key analytical and clinical aspects of cardiac biomarkers and how these may interplay in clinical practice. Measurement of high-sensitivity cardiac troponin (hs-cTn) assays is a cornerstone in the clinical evaluation of patients with symptoms and/or signs of acute cardiac ischemia. To define myocardial infarction, the Universal Definition of Myocardial Infarction requires patients who manifest with features suggestive of acute myocardial ischemia to have at least one cTn concentration above the sex-specific 99th percentile upper reference limit (URL) for hs-cTn assays and a dynamic pattern of cTn concentrations to fulfill the diagnostic criteria for MI. This special report provides an overview of how hs-cTn 99th percentile URLs should be established, including recommendations about prescreening and the number of individuals required in the reference cohort, how statistical analysis should be conducted, optimal preanalytical and analytical protocols, and analytical/biological interferences or confounds that can affect accurate determination of the 99th percentile URLs. This document also provides guidance and solutions to many of the issues posed.

Building on the ruins of empire: the Uganda Railway and the LAPSSET corridor in Kenya

Tidskriftsartikel (refereegranskat)abstract
- This article explores colonial (dis-)continuities between the planned Lamu Port–South Sudan–Ethiopia Transport (LAPSSET) development corridor and the Uganda Railway (UR). The historical approach to infrastructure studies highlights the effects of large-scale infrastructures beyond their immediate material impact, and reveals their potential power to structure mobilities, historicities and politics of scale. With reference to relational theories, it is argued that the two projects gain their respective significance not only through their ability to connect distant places, but also by blocking and severing other competing ways of being mobile. Particularly, both infrastructure projects create technologies enabling easier and faster flow of capital and commodities but limit previously prevalent mobilities practised by caravans and semi-nomadic people in the region. Both projects, furthermore, produce particular ways of remembering the past and anticipating the future. The article identifies a major discontinuity in the politics of scale they respectively imply: while the UR aimed at producing a clear scalar hierarchy between empire and colony, the LAPSSET alleges to dissolve hard boundaries between scalar instances. This article is based on qualitative data collected during fieldwork along the proposed route of the LAPSSET corridor, as well as archive work regarding the UR.

Drawing together: Making Marginal Futures Visible through Collaborative Comic Creation (CCC)
- 2020

Tidskriftsartikel (refereegranskat)abstract
- The article introduces collaborative comic creation (CCC) as a methodological tool. The central question it addresses is how marginalised imaginations of futures can be made visible in the context of the planned Lamu Port-South Sudan-Ethiopia-Transport (LAPSSET) in Kenya. The question assumes that infrastructure projects such as the LAPSSET corridor inscribe not only particular ways of moving into a landscape but also one specific temporality that marginalises other future-making practices. The paper participates in the ongoing debate about how imagined futures and future-making practices can be appreciated and analysed methodologically. It thus contributes to the literature on geographies of the future by drawing together conceptual insights from anthropology, infrastructure studies, and critical cartography. Based on these different approaches, the paper proposes to regard future-making practices not only in relation to contentious timelines but also in terms of lines made by moving and drawing on landscapes and surfaces. Using a review of existing social foresight methods as a basis, we describe the practical implementation of CCC. Subsequently, the analysis of one collaboratively produced comic illustrates how the method can help to visualise ambivalent and uncertain imaginations of different futures that oppose the unitary vision of modernity produced by dominant infrastructural visions of a single future. We conclude by reflecting on possible ways of developing the method further.

Ghostlines: Movements, Anticipations, and Drawings of the LAPSSET Development Corridor in Kenya
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Lamu Port-South Sudan-Ethiopia-Transport (LAPSSET) corridor is a partly completed development corridor in Kenya that will connect the eponymous places via roads, pipelines and railway lines, if completed. This thesis investigates how inhabitants of the traversed area navigate and shape the spatio-temporal landscape of the corridor, following three motifs: lines created through moving, anticipating, and drawing. Under moving, the thesis explores people’s encounters of LAPSSET as connection, obstacle, and repulsion, relying on mobile ethnography. In anticipating, the thesis introduces ‘spectral landscapes of anticipation’ to investigate different temporalities people create in relation to the corridor. In drawing, it considers ways of visualizing and envisioning infrastructure projects and introduces Collaborative Comic Creation as a possibility to cut through the visual normativity of infrastructural megaprojects.

Tidskriftsartikel (refereegranskat)abstract
- In this paper, we show how communities in Northern Kenya proactively engage an unfolding megaproject and the temporalities it evokes—the Lamu Port South Sudan Ethiopia Transport Corridor (LAPSSET). We argue that the latitude communities have in contending with megaprojects is broader and more dynamic than passive reception of or outright resistance against the futures promised. By introducing the concepts of entangling and fraying, we emphasise the agency communities create for themselves by appreciating their strategies and expressions of stabilising or troubling the “megaproject”. While entangling refers to practices through which communities attach additional features to an otherwise rather stable vision of its “meganess”, fraying, in contrast, describes the strands that splice off towards different spatio‐temporal imaginaries. We discuss these practices in four instances of engaging LAPSSET: constructing temporary homes at project sites; engaging in land reform; disputing land acquisition at oil exploration sites; and contesting a planned resort city.

Tidskriftsartikel (refereegranskat)abstract
- This paper investigates the importance of scale for power dynamics in the negotiation of risks connected to urban rivers in Nairobi, Kenya. In addition to unequal distribution of wealth, global inequalities in the distribution of risk become increasingly important. Scale as a significant dimension of inequality is discussed in the context of Nairobi’s urban rivers, as water scarcity and flooding events are expected to increase and can both be observed within the highly heterogenic city of Nairobi. The paper attempts to answer the overarching question: how do contested definitions of scale influence the distribution of risks in the case of informal settlement along Nairobi’s urban rivers? This contains a conceptual, as well as an empirical dimension. Regarding the conceptual part, riskscapes are introduced and subsequently expanded to include an explicitly scalar dimension. At that, riskscapes are understood as a contemporaneous (and often contradictory) plurality of material and ideational relations that connect risks with people and the environment. A relational focus on fluidity and movement interprets scalar levels as contingent and political and thus not inherent to entities but as the product of negotiable relations. This conceptual background interfaces with the methodology of multi-sited ethnography, which inspires the method of following the river through the fragmented city of Nairobi. Applying this conceptual framing to the case of urban slum-dwellers in Nairobi, it is argued that women are discursively and materially framed to the household level, where they face the highest flooding risk. The level of the body is identified as a susceptible but often neglected scalar framing and is therefore placed in the centre of empirical scrutiny. This informs the conclusion to regard the poor female body in the case of Nairobi’s urban rivers as a sacrifice-scale where risks produced elsewhere are ‘dumped’, addressing the empirical dimension of the research question. This paper’s main contribution is the conceptual merging of the politics of risk and scale, the substantiation of this argument by a relevant case study and subsequently the spotlighting of dynamics of marginalisation through scalar negotiations of risk. © 2018, Erdkunde.
