This article analyzes three video-recorded asylum interviews, their written records and the corresponding decisions by the Finnish Immigration Service. The goal is to identify the causes and consequences of vulnerability in instances that are particularly important when assessing whether the asylum seeker has a well-grounded fear of persecution. A combination of linguistic, psychological and epistemic perspectives on vulnerability shows that these three dimensions are closely intertwined in asylum interviews. Linguistic vulnerability is linked for the most part to interpreting, whereas psychological vulnerability stems from the difficulty in recounting traumatic experiences. Both linguistic and psychological vulnerabilities are central forces that also lead to epistemic vulnerability. Epistemic vulnerability, we claim, gives rise to certain practices within the asylum procedure, which again represents the materialization of the discourses of reporting, truth and credibility.

The theory of lattice deformations is presented in a new form, using the tensor calculus. The case of central forces is worked out in detail, and the results are applied to some simple hexagonal lattices. It is shown that the Bravais hexagonal lattice is unstable but the close-packed hexagonal lattice stable. The elastic constants of this lattice are calculated.

Affluence of the Heart explores the many and various ways in which waste—be it of time, stuff, money, possessions, and resources—was thought about in Japan from the immediate aftermath of devastating war to the early twenty-first century.It shows how questions about waste were deeply embedded in the decisions of the everyday and shaped by the central forces of postwar Japanese life from economic growth and mass consumption to material abundance and environmentalism.What endured from the late 1950s onward was a defining element of Japan’s postwar experience: the tension between the desire to achieve and defend the privileges of middle-class lifestyles made possible by affluence, and the discomfort and dissatisfaction with the logics, costs, and consequences of that very prosperity. This tension complicated the persistent search in these decades for what might be called well-being, happiness, or a good life. Affluence of the Heart is a history of how people lived—how they made sense of, gave meaning to, and found value in the acts of the everyday.

Digital platforms like Spotify, Netflix, and YouTube rely on mass data collection, algorithmic forms of prediction, and the development of closed digital systems. Seemingly technical and trivial, such operational and infrastructural features have both commercial and cultural consequences in need of attention. As with any other kinds of infrastructure, the surveillance practices and digital ecosystems that are now installed and solidified will have long-term effects and will be difficult to challenge. We suggest that the cultural and commercial ramifications of such datafied infrastructural developments can be unpacked by analyzing digital platforms—in this case Netflix—as surveillance-based, predictive infrastructures. Digital platforms fortify their market positions by transitioning surveillance-based assets of audience metrics into infrastructural and informational assets that set conditions for other actors and approaches at work in the domain of cultural production. We identify the central forces at play in these developments: digital platforms critically depend on proprietary surveillance data from large user bases and engage in data-structuring practices (Flyverbom and Murray 2018) that allow for predictive analytics to be a core component of their operations. Also, digital platforms engage in infrastructural development, such as Netflix’s decentralized system of video storage and content delivery, Open Connect. These meshes of user surveillance, predictive analytics, and infrastructural developments have ramifications beyond individual platforms and shape cultural production in extensive and increasingly problematic ways.

The stability of lattices is discussed from the standpoint of the method of small vibrations. It is shown that it is not necessary to determine the whole vibrational spectrum, but only its long wave part. The stability conditions are nothing but the positive definiteness of the macroscopic deformation energy, and can be expressed in the form of inequalities for the elastic constants. A new method is explained for calculating these as lattice sums, and this method is applied to the three monatomic lattice types assuming central forces. In this way one obtains a simple explanation of the fact that the face-centred lattice is stable, whereas the simple lattice is always unstable and the body-centred also except for small exponents of the attractive forces. It is indicated that this method might be used for an improvement of the, at present, rather unsatisfactory theory of strength.
