This chapter addresses the question as to how the Christian devout life is related to contemporary holistic spirituality, taking C. G. Jung as representative of holistic spirituality’s quest to balance the binary elements of the self. By way of contrast, Christian spirituality might seem to require the hierarchical subordination of one part of the self to another, reinforcing suspicions as to its essentially heteronomous nature. Nevertheless, the devout life can be shown to be a life involving the coordination of ‘body, mind, and spirit’. Where contemporary holism emphasizes the spatial balancing of the self the devout life integrates spatial and temporal dimensions of selfhood seeking to be focused on the sacrament of the present moment as it moves forward in tranquillity and equanimity.

Abstract Despite the ubiquitous mechanical cues at both spatial and temporal dimensions, cell identities and functions are largely immune to the everchanging mechanical stimuli. To understand the molecular basis of this epigenetic stability, we interrogated compressive force-elicited transcriptomic changes in mesenchymal stem cells purified from human periodontal ligament (PDLSCs), and identified H3K27me3 and E2F signatures populated within upregulated and weakly downregulated genes, respectively. Consistently, expressions of several E2F family transcription factors and EZH2, as core methyltransferase for H3K27me3, decreased in response to mechanical stress, which were attributed to force-induced redistribution of RB from nucleoplasm to lamina. Importantly, although epigenomic analysis on H3K27me3 landscape only demonstrated correlating changes at one group of mechanoresponsive genes, we observed a genome-wide destabilization of super-enhancers along with aberrant EZH2 retention. These super-enhancers were tightly bounded by H3K27me3 domain on one side and exhibited attenuating H3K27ac deposition and flattening H3K27ac peaks along with compensated EZH2 expression after force exposure, analogous to increased H3K27ac entropy or decreased H3K27ac polarization. Interference of force-induced EZH2 reduction could drive actin filaments dependent spatial overlap between EZH2 and super-enhancers and functionally compromise the multipotency of PDLSC following mechanical stress. These findings together unveil a specific contribution of EZH2 reduction for the maintenance of super-enhancer stability and cell identity in mechanoresponse.

Dynamic segmentation is viewed as one of the most important functions of geographic information systems for transportation applications. Although the road network and associated events (e.g., pavement material, traffic volume, incidents) can be referenced to both space and time, the spatial and temporal dimensions have not been well integrated. Modeling space-varying, time-varying, and space-time-varying events in dynamic segmentation by using an object database approach that is in line with the Object Database Management Group standard is explored. A mechanism called parametric polymorphism is used to lift conventional data types to spatial, temporal, and spatiotemporal types for maintaining knowledge about events that could change spatially, temporally, and spatiotemporally along linear features. An associated object query language, DS-OQL, was designed to support the formulation of spatial, temporal, and spatiotemporal queries on the road and event information.

AbstractTraditionally, the art market is associated with specific cities or art districts; typically there are internationally renowned locations like Paris, New York and Berlin. However, taking a closer look at the art markets, it is rather the temporal dimensions that are striking. Art market actors (e. g. artists, critics, gallerists, buyers, collectors, curators) are gathering in temporary locations and at temporary events such as art exhibition openings, art fairs, auctions, performances and vernissages. Within economic geography literature, the role of temporary spaces and events has been increasingly discussed in relation to economic activities and their performance, efficiency and creativity. An important insight gained in this literature is how temporary events, despite their short-lived existence, create microcosms of an industry or sector. Some temporary events even gather enough resources, skills and power to become field-configuring. In this paper, the primary art market will be discussed from the theoretical perspectives of value-making processes, temporary spaces and events, and field-configuring events. More specifically, the study focuses on temporary spaces important to galleries involved in selling and promoting primary art and artists. It focuses on how temporary spaces constitute both a characteristic feature of the art market and important spaces for creating both cultural and economic values. Empirically, this paper is based on a study of the Swedish primary art galleries and in particular it deals with primary art galleries located in Stockholm, and studies how they use temporary spaces and events in creating both cultural and economic values to themselves, the artists and their artworks. Three empirical examples characteristic to primary art galleries are examined; the opening, the art fair and the mobile art district.

The current understanding of entrepreneurial action is grounded in time, but the different facets of this time remain to be sufficiently explored. We argue that entrepreneurial action has two temporal dimensions: world time and human time. World time reveals the prior contextual conditions giving rise to entrepreneurial actions that generate subsequent results. Human time reveals how entrepreneurs act on the basis of past experiences, attention to current conditions, and images of the future. Using a narrative framework to integrate world time and human time, we contribute to a deeper understanding of the different facets of time in entrepreneurial action.

A proposta central deste artigo é analisar as representações sobre as cidades que irrompem nos fragmentos dos diversos relatos e registros dos seus habitantes. Nos “relatos de espaço”, homens e mulheres codificam e distinguem simbolicamente espaços e lugares, imbricados às várias temporalidades. Reunidos em uma trama narrativa, sinalizam práticas culturais, organizadoras dos espaços e constitutivas das configurações urbanas. Abstract: The central proposal of this article is to analyze the representations about the cities that emerge in the fragments of several reports and records of their inhabitants. In the “reports of the space” men and women codify and distinguish symbolically spaces and places, which are connected to several temporal dimensions. Gathered in a narrative plot, they show cultural practices that are organizers of the spaces and constitutive of the urban configurations. Palavras-chave: Cidade. História. Memória. Key words: City. History. Memory.
