Reconciliation through reintegration? : a study on spatial proximity and social relations in two post-civil war Beirut neighborhoods
… the extent to which and under what conditions spatial proximity actually leads to social relations between non-co-religionists. Integration alone does not seem to guarantee interaction. Factors limiting cross-sectarian interaction within the same neighborhood appear to include an absence of …

Community composition, demographic change, and the impact of spatial proximity to disadvantage on violence and gang presence in New Jersey municipalities
… of research, however, that explores whether spatial proximity to disadvantaged areas affects crime and gang presence in nearby locations. Through maps and spatial analysis, this study investigates how neighborhood demographics may vary and may have changed by community type in New Jersey …

Mechanisms driving social structure in Octodon degus
… (2022–2023), we tested the roles of nighttime spatial proximity, female social cohesion, and female homophily based on masculinization (anogenital distance) in shaping social associations. Nighttime spatial proximity was negatively associated with association strength, indicating that …

Information Technology and Its Transformational Effect on the Health Care Industry
… Essay 1: The Impact of Firm Characteristics and Spatial Proximity on the Diffusion of Electronic Medical Records: A Hazard Modeling Analysis. This study, positioned at the inter-organizational level, draws upon adoption and diffusion literature to predict the likelihood of EMR adoption by …

Proximity-based systems: Incorporating mobility and scalability through proximity sensing
This thesis argues that the concept of spatial proximity offers a viable and practical option for the development of context-aware systems for highly mobile and dynamic environments. Such systems would overcome the shortcomings experienced by today’s location-based and infrastructure dependent …

Monuments and the construction of the past in early historic Ireland
… the sites of battles and assemblies, and their spatial proximity to - or even incorporation within - ecclesiastical or royal sites.

Dynamics and architectures of innovation systems
… Three key elements, knowledge diversity, spatial proximity, and strategic relatedness, are found to be fundamental to innovations after analyzing and comparing different studies. However, these three factors derived from resource-based view and knowledge-based view do not seem sufficient …

The role of proximity in human-agent trust
This dissertation examines how different forms of proximity—visual, cognitive, and spatial shape human trust and collaboration with embodied agents. As AI systems increasingly operate as social partners in virtual and mixed reality contexts, understanding the mechanisms that foster or erode trust …

Microbial Ecology: Spatial Aspects of Pesticide Degradation
… under a range of soil moisture conditions. Spatial proximity of xenobiotic had a substantial effect on the extent of degradation, with an additional effect of moisture content. Simultaneous addition of the compound and the degrader to the soil resulted in reduced mineralization dependence on …

Sense Your Neighbor: Design for Bridging Social Capital in Diverse Spaces
… the neighborhood, particularly in terms of the spatial proximity of different social groups. Proponents of mixed-income communities cite the potential for the formation of Bridging Social Capital (i.e., benefits, such as improved educational or employment opportunities, shared via casual ties …

Building an Intelligent Filtering System Using Idea Indexing
… simplicity, fast speed, and the appeal of using spatial proximity for semantic proximity. However, this model faces a disadvantage that is associated with the vagueness from keywords overlapping. Efforts have been made to improve the vector model. The research on improving document representation …

A Multi-Stage Optimization Framework for Battery Swapping in Urban E-Bike Sharing Systems
… van-feasible clusters based on battery level, spatial proximity, and fleet availability. Each cluster is then optimized to minimize travel distance while maximizing economic return. The framework is applied to real-world data from San Francisco’s Bay Wheels system, accessed via the General …

Identification of components required for mitophagy and mitochondrial inheritance by genetic screens in yeast
… in the ERMES mutants, indicating that loss of spatial proximity between the two organelles is the main cause of the mitophagy deficit. Moreover, one of the ERMES subunits interacts with the autophagic membrane expansion factor Atg8, which suggests that ERMES plays a role during growth of this …

Measure of Global Specialization and Spatial Clustering for the Identification of "Specialized" Agglomeration
… of the economy. Thus, the identification of spatial boundaries to measure specialization becomes critical, since most likely the model will be adapted to different scales of distance, and be influenced by different types of externalities or economies of agglomeration, which are based on the …

Touch-and-go chemistry: development of materials for and demonstration of a contact-initiated polymerization
… once two or more reactive molecules come into proximity in the correct orientation. Enzymatic reactions display improved reaction rates because catalytic groups are prearranged in proximity to the substrate. It follows that one can control a reaction rate by controlling the spatial proximity of …

Operational Dynamics of Technology Diffusion: Evidence From Patenting Data
… related to the ""geography of innovation"" or ""spatial clustering of innovations"". The relationship between innovation and geography is a topic of growing interest in both economics and regional science. The main questions are the extent to which knowledge spillovers (knowledge externalities) …

Modeling the Efficacy of the 15-Minute City Using Large-Scale Mobility Data from the Perspective of Accessibility and User Choice: A Case Study on the Urban Food Environment
… implies that accessibility can be quantified by proximity, and that people are more likely to visit amenities that are physically closer to them. In this study, we investigate the relationship between choice and spatial proximity in the context of healthy food accessibility by modeling an …

3D Chromatin Structure and Gene Regulation: Integrated Genome Structure, Transcriptomics and Epigenetics
… structures. These analyses reveal that spatial proximity between eQTL–eGene pairs enhances regulatory effects and that many-body interactions underpin tissue-specific expression. To enable systematic exploration, I created ChromPolymerDB, a high-resolution public database of ~10⁸ …

Hierarchy of Interactions in Protein Evolution
… a model for this pattern that is distinct from spatial proximity in tertiary structure, positional conservation, or even other forms of co-evolution. Here, we use an extension of deep mutational scanning to analyze nearly 50,000 single and double mutations in several homologs of a model protein …

Bluefish: A Grammar of Discrete Diagrams
… Perceptual grouping principles – such as spatial proximity, nesting, and linking – are central to reading a discrete diagram. Yet, despite their importance, these principles are typically only implicit when creating one. As a result, a diagram author must either build their own …
