Abstract:
AbstractMicroplastic pollution is a ubiquitous environmental threat, in particular to the oceans. In the marine environment, microplastics are not just passively transported by sea currents, but often get contaminated with organic pollutants during the journey. The uptake of chemicals onto microplastics can worsen the adverse effects of microplastics to marine organisms; however, investigation on this urgent phenomenon is hampered by the impossibility of monitoring and tracking such small plastic fragments during their motion at sea. This work aims at addressing the need for an effective modelling of the advection–diffusion processes jointly involving microplastics and the pollutants they carry to further our understanding of their spatiotemporal patterns and ecological impacts, focusing on the Mediterranean Sea. Here we present the conceptual design, methodological settings, and modelling results of a novel, data-informed 2D Lagrangian–Eulerian modelling framework that simultaneously describes (i) the Lagrangian dispersal of microplastic on the sea surface, (ii) the Eulerian advection–diffusion of selected organic contaminants, and (iii) the gradient-driven chemical exchanges between microplastic particles and chemical pollutants in the marine environment in a simple, yet comprehensive way. Crucial to the realism of our model is exploiting the wide variety and abundance of data linked with drivers of Mediterranean marine pollution by microplastics and chemicals, ranging from national censuses to satellite data of surface water runoff and GPS ship tracking, other than the use of oceanographic reanalyses to inform microplastics’ motion at sea. The results of our method applied to a multi-year simulation contribute to a first basin-wide assessment of the role of microplastics as a vehicle of other pollutants of concern in the marine environment. The framework proposed here is intended as a flexible tool to help advance knowledge towards a comprehensive description of the multifaceted threat of marine plastic pollution and an informed support to targeted mitigation policies.

Abstract:
In addition to the spectrum model, I also introduced an interaction model to characterize the brain’s neural activity (chapter 2). Is the interaction model of brain also relevant for consciousness? That is the focus in the present chapter. I here present various lines of empirical evidence focusing on disorders of consciousness like vegetative state, anesthesia, and sleep. Based on empirical evidence, I show that the degree of non-additive interaction between spontaneous and stimulus-induced activity indexes the level of consciousness in a seemingly rather fine-grained way; for that reason, it may be considered a neural correlate of the level of consciousness, i.e., NCC. In contrast, the spontaneous activity and its spatiotemporal structure is rather a necessary condition of possible consciousness, that is, a neural predisposition of consciousness (NPC). The concept of NPC is further enriched by the concept of capacities for which I recruit Nancy Cartwright. I suggest that the brain’s non-additive interaction including the subsequent association of stimulus-induced activity with consciousness is based on the spontaneous activity’s capacity. Since that very same capacity, operating as NPC, can be traced to the spontaneous activity’s spatiotemporal features, I speak of “spatiotemporal capacity”. I conclude that the empirical data suggest a capacity-based approach (rather than law-based approach) to the brain and how it is related to consciousness.

This chapter examine the interaction of roots and routes, tradition and mobility, in contemporary Galician audiovisual culture, focusing on the cultural resignification of the ancient pilgrim’s Road to Saint James (Camino de Santiago) in the global age, and the transformation of Santiago de Compostela into a global theme park of Galicianness. It examines several audiovisual productions by Chano Piñeiro, The Chieftains, and Carlos Núñez that metaphorically travel in time and space, where experimentation with cinema and Celtic music merges old and modern forms and transcends spatiotemporal barriers, repositioning Galician culture on the global map.

Abstract:
A number of qualitative calculi have been developed in order to reason about space and time. A recent trend has been the emergence of integrated spatiotemporal calculi in order to deal with dynamic phenomena such as motion. In 2004, Van de Weghe introduced the Qualitative Trajectory Calculus (QTC) as a qualitative calculus to represent and reason about moving objects. This chapter presents a general overview of the principal theoretical aspects of QTC, focusing on the two most fundamental types of QTC. It shows how QTC deals with important reasoning concepts and how calculus can be employed in order to represent raw moving object data.

Abstract:
In this chapter, the authors examine what they call “alma mater” school shootings - those in which a current or former student returns to attack people at the school. In this case, the focus is on K-12 school shootings in the United States between 1990 and 2018 where two or more individuals were killed. They argue that many shooters target their alma mater because it is the place where they have experienced “place trauma” - emotional pain that is intertwined with a location. After discerning common demographic, personal, and spatiotemporal patterns, they discuss how the shooters acquired the firearms used to carry out the attack. Finally, the authors outline policy and practice considerations focusing on education, school funding, and legislation.

Abstract:
Is the spectrum model of brain and its assumption of the hybrid nature of stimulus-induced activity relevant for consciousness? That is the focus in the present chapter. I here present various lines of empirical evidence focusing on disorders of consciousness like vegetative state, anesthesia, and sleep. These findings suggest that the loss of consciousness in vegetative state, anesthesia, and sleep is characterized by the loss of the hybrid nature of stimulus-induced activity which shifts more towards the passive pole. This lets me suppose that the hybrid nature of stimulus-induced activity including its spatiotemporal integration as postulated in the spectrum model is central for the level of consciousness. I therefore conclude that the spectrum model of brain is relevant for consciousness.

Abstract:
This work summarizes preliminary results of a spatiotemporal analysis focusing on changes in the occurrence of fire danger extremes in Europe between 1980 and 2019. Extreme danger days were defined based on the daily severity rating exceeding the locally defined 95th percentile. For the 2001 – 2019 period, we show that extreme fire danger days and total burnt area have a positive relationship across Europe, albeit stronger in the eastern half of it. Trend analysis results indicate that extreme fire danger days have overall increased in Europe, with the largest increases found in the north-eastern regions. Further, we illustrate that these increases may be related to abrupt shifts in the means, especially over the south-west Mediterranean, and central and north-eastern Europe. These shifts took place primarily during the 1990s, marking large increases in the mean annual number of extreme fire danger days before and after the years of change.

Abstract:
This essay explores how the distinct sexual economy of queer sex publics shapes black queer subjectivity. Focusing on how the illicit economies of the street and the illicit sexual labor of black same-sex desiring men overlap in queer sex publics, sometimes posing a threat to black men engaging in such “risky” sexual activity, this chapter argues that black queer subjectivity emerges precisely within these spatiotemporal entanglements of death and desire. Through close readings of two short stories by Jamaican-American gay author G. Winston James, the first scholarly treatment of his work to date, the author explores literary representations of black gay protagonists who encounter death while cruising for sex. The author ultimately calls for a queer reading practice that holds representations of death, oftentimes central to black queer narratives, in critical tension with representations of black queer desire.

Abstract:
Focusing on the early work of three well-known American Romantic authors who are not best known as travel writers, Nathaniel Hawthorne, Margaret Fuller, and Henry David Thoreau, the first chapter examines the midcentury rise in popularity of the picturesque travel sketch genre. Writers engaged in this genre used the picturesque to consider the effects of history on the landscape and meditate on America’s past and future. Although modern scholarship has typically dismissed the picturesque travel sketch as superficial, this chapter demonstrates that writers used the spatiotemporal protocols of the picturesque to think through American exceptionalism, particularly the view that the frontier landscape helps to make the nation unique. This topic is filtered through the travelers’ views of picturesque scenery that touch upon the relationship of human to natural time (“deep time”), the resonances of the national past on the present (particularly in the residual presence of Native Americans and the colonial past), and the future effects of spatial expansion and new people (particularly immigrants) on the American landscape.
