This study follows A.N. Krylov’s recommendations on accelerating the convergence of the Fourier series, to obtain explicit expressions of the classical mixed problem–solution for a non-homogeneous equation and explicit expressions of the generalized solution in the case of arbitrary summable functions q(x), ϕ(x), y(x), f(x, t).

This chapter draws on data from U.S. higher education to analyze the ways that the language used to describe sexual harassment secures its continued power. Focusing on two features viewed as definitional to sexual harassment, frequency and severity, the discussion analyzes three sets of online conversations about the disclosure of abuse in academia (a series of tweets, survey responses, and posts on a philosophy blog) from grammatical, pragmatic, and semiotic perspectives. Unlike most prior research, this chapter focuses on the language of victims rather than the intentions of harassers. The results suggest that speech act theory is unable to account fully for sexual harassment without accepting the relevance of perlocutionary effects. Using Gal and Irvine’s (2019) model of axes of differentiation, the chapter demonstrates how opposing discursive representations (of professors, sexual harassers, victims, and accusers) create a discursive space in which it becomes difficult for victims to report their harassers.

The Future

COVID-19 has loosened neoliberalism’s hegemonic grip on the future. Amid the enormous suffering experienced internationally, there is much discussion of how to ‘Build Back Better’, and hope for a more caring, just and sustainable world. But competing futures are being imagined and planned. Hope is never politically neutral, and the content of collective hope is a key site of political struggle. This is partly a question of space: who has the literal and discursive space in which to develop visions of the future? The following article considers the role that cultural studies can play in this struggle. ‘Conjunctural analysis’ has a key task, making visible the competing futures contained within the present. But cultural studies should go further: combining conjunctural analysis with methods drawn from a range of scholarly and activist traditions – including critical pedagogy, devised theatre and the interdisciplinary field of futures studies – that deliberately create spaces for imagining new futures.

The research presented in this paper describes an evaluation of the impact of spatial interventions in public spaces, measured by social media data. This contribution aims at observing the way a spatial intervention in an urban location can affect what people talk about on social media. The test site for our research is Domplatz in the center of Hamburg, Germany. In recent years, several actions have taken place there, intending to attract social activity and spotlight the square as a landmark of cultural discourse in the city of Hamburg. To evaluate the impact of this strategy, textual data from the social networks Twitter and Instagram (i.e., tweets and image captions) are collected and analyzed using Natural Language Processing intelligence. These analyses identify and track the cultural topic or “people talking about culture” in the city of Hamburg. We observe the evolution of the cultural topic, and its potential correspondence in levels of activity, with certain intervention actions carried out in Domplatz. Two analytic methods of topic clustering and tracking are tested. The results show a successful topic identification and tracking with both methods, the second one being more accurate. This means that it is possible to isolate and observe the evolution of the city’s cultural discourse using NLP. However, it is shown that the effects of spatial interventions in our small test square have a limited local scale, rather than a city-wide relevance.

Health And Healing

The Japanese “new religions” ( Shin Shūkyō) active in Kinshasa (DR Congo) nearly all perform healing through the channeling of invisible divine light. In the case of Sekai Kyūseikyō (Church of World Messianity), the light of Johrei cannot be visually apprehended, but is worn as an invisible aura on the practitioner’s body. This article discusses the trans-cultural resonances between Japan and Central Africa regarding the ontology of spiritual force, regimes of subjectivity, and the gradual embodiment of Johrei divine light as a protection against (suspicions of) witchcraft. Meanwhile, I argue that religious multiplicity in urban Africa encourages cultural reflexivity about concepts of health and healing, self-responsibility, and Pentecostal suspicion-mongering of occult sciences. Thus, Johrei divine light not only feeds into a longstanding local tradition of spiritual healing; within the religiously multiple city, it is also a discursive space for, and an experience and performance of, emic critique.

ABSTRACTThe paper is concerned with the construction of polynomials in two variables, which form a complete orthogonal set for the interior of the unit circle and which are ‘invariant in form’ with respect to rotations of axes about the origin of coordinates. It is found that though there exist an infinity of such sets there is only one set which in addition has certain simple properties strictly analogous to that of Legendre polynomials. This set is found to be identical with the set of the circle polynomials of Zernike which play an important part in the theory of phase contrast and in the Nijboer-Zernike diffraction theory of optical aberrations.The results make it possible to derive explicit expressions for the Zernike polynomials in a simple, systematic manner. The method employed may also be used to derive other orthogonal sets. One new set is investigated, and the generating functions for this set and for the Zernike polynomials are also given.

AbstractA method of finding explicit expressions for the roots of a certain class of transcendental equations is discussed. In particular it is shown by determining a canonical solution of an associated Riemann boundary-value problem that expressions for the roots may be derived in closed form. The explicit solutions to two transcendental equations, tan β = ωβ and β tan β = ω, are discussed in detail, and additional specific results are given.

To apply the theorem of Nekhoroshev (1977) to asteroids, one first has to check whether a necessary geometrical condition is fulfilled: either convexity, or quasi-convexity, or only a 3-jet non-degeneracy. This requires computation of the derivatives of the integrable part of the corresponding Hamiltonian up to the third order over actions and a thorough analysis of their properties. In this paper we describe in detail the procedure of derivation and we give explicit expressions for the obtained derivatives. .
