Abstract: Dream research is entering a new era of accelerating insights and discoveries, thanks to the rise of powerful digital analysis tools that are enabling important advances in the empirical study of dreams. This paper illustrates the use of these tools, drawing on the resources of the Sleep and Dream Database, a free online archive of information about sleep and dreaming. These tools include statistical analyses of survey responses, systematic word searches of large collections of dream reports, and a well-grounded set of baseline frequencies to help with comparative measurement. The goal of this paper is to provide readers with an initial orienta-tion to the new world of dream discovery that has opened up because of tools like these. Several basic empirical findings are presented regarding clearly observable patterns of perception, emotion, and social interaction in dreaming. The paper will close with reflections on the emerging interplay of dreaming and technology.

Abstract: The aim of the current study was to explore the impact of the CoVID-19 out-break on the dreams of a group of Italian participants. a total of 403 individuals were recruited online through a cross-sectional survey on Moodle. The qualitati-ve content of their dreams was analysed using the Dream Interview (TKYDQ), a tool created by Bulkeley. In addition, the Pittsburgh Sleep Quality Index (PSQI) was used to assess the quantitative aspects of dreams. from the results of our stu-dy, three macro-categories of content in the participants' dreams were identified: 1) dreams with phobic content; 2) dreams with a persecutory theme and 3) “old normal” dreams. Moreover, some sleep-related difficulties such as problems falling asleep and mild clinical sleep disorders were identified in the sample. The pro-longed quarantine and the lifestyle adopted during the pandemic have intensely influenced our dream activities, and it seems that CoVID-19 has already entered our collective unconscious in a symbolic way and through the processing of images and scenes related to the epidemic. The study, therefore, aims to explore how cata-strophic events affect mental health, specifically sleep quality and dream content.

Abstract: The historiography of dreams has yet to emerge as a distinct field, and key changes in dream research are worthy of consideration to reflect on tacit knowled-ge in academia. Gesturing toward such a historiography, the historical construc-tion of the “dream” is examined from a discursive perspective via localization in the internal/external and subjective/objective, communicative and social imagined spaces of dreams, as well as the theoretical paradigms of essentialism and contextu-alism. Premodern to post-postmodern epistemes are considered as shaping forces in these discourses, involving power and authority in determining what counts as legitimate or significant knowledge. The discussion concludes with reflections on the current state of dream research from a post-postmodern perspective, suggesting the ontological multiplicity of the “dream.”

Abstract: For a set ${\mathcal Q}$ of points in the plane and a real number $\delta \ge 0$, let $\mathbb{G}_\delta({\mathcal Q})$ be the graph defined on ${\mathcal Q}$ by connecting each pair of points at distance at most $\delta$. We consider the connectivity of $\mathbb{G}_\delta({\mathcal Q})$ in the best scenario when the location of a few of the points is uncertain, but we know for each uncertain point a line segment that contains it. More precisely, we consider the following optimization problem: given a set ${\mathcal P}$ of $n-k$ points in the plane and a set ${\mathcal S}$ of $k$ line segments in the plane, find the minimum $\delta \ge 0$ with the property that we can select one point $p_s\in s$ for each segment $s\in {\mathcal S}$ and the corresponding graph $\mathbb{G}_\delta( {\mathcal P}\cup \{ p_s\mid s\in {\mathcal S}\})$ is connected. It is known that the problem is NP-hard. We provide an algorithm to exactly compute an optimal solution in ${\mathcal O}(f(k) n \log n)$ time, for a computable function $f(\cdot)$. This implies that the problem is FPT when parameterized by $k$. The best previous algorithm uses ${\mathcal O}((k!)^k k^{k+1}\cdot n^{2k})$ time and computes the solution up to fixed precision.

Abstract: V prispevku je opazovan diskurz, ki se je v Avstrijskem primorju (zlasti v Trstu) sple-tal okrog razprav o higienizaciji in asanaciji urbanega prostora. Pri tem so izpostavljeni od konca 19. stoletja naraščajoč družbeni pomen higiene v najširšem smislu, zavedanje o pomenu bivanjskih pogojev v urbanem prostoru ter vpliv socialnih okoliščin na otroško umr-ljivost. Slednja je bila namreč eden ključnih medicinskih, higienskih, moralnih in političnih argumentov za prikaz pomanjkljivih prizadevanj na področju zdravstvene preventive ter hkrati podlaga za širjenje modernih, z napredkom povezanih (meščanskih) idej, tudi skozi imperative, ki so naslavljali materinsko nego. Poleg tega je kvantitativni del analize podobno kot za Trst tudi za Koper vsaj deloma pokazal, da je bil velik delež smrti med otroki do petega leta starosti verjetno povezan prav s socialno deprivacijo tako z vidika higiene in prehrane kot profilakse in medicinske kurative.
