The transient impact of the African monsoon on Plio-Pleistocene Mediterranean sediments
No full textOver the Plio-Pleistocene interval a strong linkage exists between northern African climate changes and the supply of dust over the surrounding oceans and continental runoff towards the Mediterranean Sea. Both these signatures in the sedimentary record are determined by orbital cycles influencing glacial variability on the one hand and northern African monsoon intensity on the other hand. In this paper, we use the intermediate-complexity model CLIMBER-2 to simulate African climate during the Plio-Pleistocene between 3.2 and 2.3 million years ago (Ma) and compare our simulations with the sedimentary records of marine sediment cores from ODP Site 659 (Atlantic Ocean) and ODP Site 967 (Mediterranean). In this study we will show for the first time an extended Ti-Al record of Site 967 down to 3.2 Ma

How Scientific Instruments Speak: Postphenomenology and Technological Mediations in Neuroscientific Practice
No full textScience is highly dependent on technologies to observe scientific objects. For example, astronomers need telescopes to observe planetary movements, and cognitive neuroscience depends on brain imaging technologies to investigate human cognition. But how do such technologies shape scientific practice, and how do new scientific objects come into being when new technologies are used in science? In How Scientific Instruments Speak, Bas de Boer develops a philosophical account of how technologies shape the reality that scientists study, arguing that we should understand scientific instruments as mediating technologies. Rather than mute tools serving pre-existing human goals, scientific instruments play an active role in shaping scientific work. De Boer uses this account to discuss how brain imaging and stimulation technologies mediate the way in which cognitive neuroscientists investigate human cognitive functions. The development of cognitive neuroscience runs parallel with the development of advanced brain imaging technologies, drawing a lot of public attention—sometimes called “neurohype”—because of its alleged capacity to demystify the human mind. By analyzing how the objects that cognitive neuroscientists study are mediated by brain imaging technologies, de Boer explicates the processes by which human cognition is investigated

The Historical Evolution of Regionalizing Identities in Europe:Introduction
No full textThis introduction to a multidisciplinary volume, discusses theoretical approaches to ideas of collective and narrative identity, based on the fundamental work of Jan and Aleida Assmann, Paul Ricoeur, and Peter Burke, as a background for the the research carried out by three collaborative research projects under the European Science Foundation , 2010-2014. Together, these projects formed the research programme EuroCORECODE concerned with European national and regional identities, historically as well as in contemporary Europe. In the text, the three projects are also introduced by the authors, who served as their project leaders
Chapter 9 Attending to Your Lifestyle: Self-Tracking Technologies and Relevance
No full textThis chapter intends to develop a phenomenological analysis of how self-tracking technologies structure attention. The goal of this analysis is to highlight how the use of such technologies - ones that are already used frequently, and will likely become part of the lives of many more individuals in the future - turn our body and habits into objects of relevance. The outline is as follows: First, I discuss some technological developments that intend to promote a healthy lifestyle (1). Second, I suggest, elaborating on insights from postphenomenology, that technologies mediate what appears as relevant by shaping the relation between human beings and the world (2). Third, I further unpack the implications of this idea by connecting it to Alfred Schütz's theory of relevance. I suggest how self-tracking technologies shape systems of topical, interpretational, and motivational relevances (3). Fourth, I argue that what stands out as relevant is constituted through sedimented habits, as well as the projects in which people engage (4). Fifth, I suggest that technologies that are designed to help people pursue a healthy lifestyle turn the attention of users towards their own body in ways that often remain unnoticed, such that it might become increasingly difficult to turn attention towards other objects and projects that might be equally relevant (5). In conclusion, I suggest that such technologies privilege a particular view of health that might become an unquestionable element of the lifeworld, and that this view might remain unnoticed when not being subject to careful analysis (6)

Bringing disgust in through the backdoor in healthy food promotion: a phenomenological perspective
Full text linkObesity has been pointed out as one of the main current health risks leading to calls for a so-called “war on obesity”. As we show in this paper, activities that attempt to counter obesity by persuading people to adjust a specific behavior often employ a pedagogy of regret and disgust. Nowadays, however, public healthcare campaigns that aim to tackle obesity have often replaced or augmented the explicit negative depictions of obesity and/or excessive food intake with the positive promotion of healthy food items. In this paper, we draw on a phenomenological perspective on disgust to highlight that food-related disgust is connected to the character and behavior of a perceived individual even in the context of promoting healthy food items. We argue that the focus on “making the healthy food choice the easy choice” might be an important step towards the de-stigmatization of people that are affected by obesity. However, so we suggest, this focus threatens to bring back an image of individuals affected by obesity as disgusting “through the backdoor”. It does so not by portraying bodies with overweight as disgusting, but instead by implying that lifestyle choices, character and habits of people that are affected by obesity are markers of a lack of control. We argue that the close relationship between disgust and the perception of self-control in the context of obesity should be taken into consideration in the context of assessing the implications of new health promotion strategies to minimize the risk of stigmatizing people
