WHY GOD WAS AN ICONOCLAST? THE VISUAL AND THE PICTORIAL IN BIBLICAL HIEROTOPY

This study’s point of departure is a question: given that the Old Testament God so categorically prohibits all images, why is His Word, i.e., the Bible, so full of visions and visual imagery? In this paper, the issue is discussed in terms of a distinction between the visual, broadly understood, and the pictorial, relating in a narrow sense to graphic artefacts. I argue that mental images are distinct from and, in a sense, superior to pictures. The latter are contrasted with an ‘enhanced’ visual imagery that includes sensory and motor images as well. Holistic units of these ‘enhanced’ visual memories are termed as ‘image-experiences’. The first and most important quality of the ‘enhanced vision’ is its spatial character, which can even predetermine the emotional key of the response. This is particularly the case with ‘limitless’ natural spaces, such as the sea, the skies, or mountainous landscapes. The complex structure of the natural sublime and its affinity with divine imagery is discussed using the concrete example of the modern European aesthetics of mountains in its historical evolution. Then the paper turns to the hierotopic approach, according to which the spatial experience of religious imagery emerges from organized ensembles of sacred objects and symbolic pointers, conceptualised as spatial icons. Another important quality of the enhanced visual is in its organic link with movement and action. Image-experiences are lived through rather than passively watched. Calvinist visual theology provides a remarkable example of an iconoclast ideology, which explicitly supports the ‘enhanced visual’ and shows a way to develop it into a form of understanding and transforming the world. The motional/actional aspects of the ‘enhanced’ visual are further discussed in terms of a hierarchical model of motion control proposed by Nikolai Bernstein in which two kinds of spaces are defined: first, space as a geometric medium of locomotion defined by delimiting surfaces and dynamic constraints; secondly, spaces of purposeful tool-mediated activity as collections of meaningful objects. Our human talent for identifying things by unclear or incomplete features is instrumental to our ability to recognize objects in drawings and photographs. The Bernsteinian system helps to explain why the perception of 2D images is dominated by object-oriented parsing. Hence, there is a danger that the response to pictures be reduced to subject-object interaction in which many important holistic qualities of the enhanced visual would be lost. Hierotopic creativity – the construction of sacred spaces – can be seen as a strategy to mitigate these dangers by integrating image-pictures into higher-level spatial constructs of enhanced visuality.This study’s point of departure is a question: given that the Old Testament God so categorically prohibits all images, why is His Word, i.e., the Bible, so full of visions and visual imagery?

Microgrids & District Energy: Pathways To Sustainable Urban Development

A microgrid is an energy system specifically designed to meet some of the energy needs of a group of buildings, a campus, or an entire community. It can include local facilities that generate electricity, heating, and/or cooling; store energy; distribute the energy generated; and manage energy consumption intelligently and in real time. Microgrids enable economies of scale that facilitate local production of energy in ways that can advance cost reduction, sustainability, economic development, and resilience goals. As they often involve multiple stakeholders, and may encompass numerous distinct property boundaries, municipal involvement is often a key factor for successful implementation. This report provides an introduction to microgrid concepts, identifies the benefits and most common road blocks to implementation, and discusses proactive steps municipalities can take to advance economically viable and environmentally superior microgrids. It also offers advocacy suggestions for municipal leaders and officials to pursue at the state and regional level. The contents are targeted to municipal government staff but anyone looking for introductory material on microgrids should find it useful

Mobile Wireless Sensor Networks: An Overview

Mobile wireless sensor networks (MWSNs) have emerged and shifted the focus from the typical static wireless sensor networks to networks with mobile sensor nodes that are capable to sense the various types of events. Also, they can change their position frequently in a specific sensing area. The applications of the MWSNs can be widely divided into time-driven, event-driven, on-demand and tracking based applications. Mobile sensor node architecture, residual energy utilization, mobility, topology, scalability, localization, data collection routing, Quality of Service (QoS), etc., are the key factors to design an energy efficient MWSNs for some specific purpose. This chapter deals with an overview of the MWSNs and a few significant phenomena to design an energy efficient MWSNs to the large-scale environment

Mapping heterogeneous buried archaeological features using multisensor data from unmanned aerial vehicles

There is a long history of the use of aerial imagery for archaeological research, but the application of multisensor image data has only recently been facilitated by the development of unmanned aerial vehicles (UAVs). Two archaeological sites in the East Midlands U.K. that differ in age and topography were selected for survey using multisensor imaging from a fixed-wing UAV. The aim of this study was to determine optimum methodology for the use of UAVs in examining archaeological sites that have no obvious surface features and examine issues of ground control target design, thermal effects, image processing and advanced filtration. The information derived from the range of sensors used in this study enabled interpretation of buried archaeology at both sites. For any archaeological survey using UAVs, the acquisition of visible colour (RGB), multispectral, and thermal imagery as a minimum are advised, as no single technique is sufficient to attempt to reveal the maximum amount of potential information

Reconsidering Academic Dishonesty: A Critical Examination of a Complex Organizational Problem

Academic dishonesty, traditionally framed as a problem of student agency, plagues higher education institutions. In order to facilitate leadership toward the resolution of the problem, this study reconsiders academic dishonesty as a symptom of the complex interplay among agency, structure, and culture. The theoretical framework utilized, which I call Systemic Interactionism, builds on existing sociological, leadership, and organizational theories to provide a more robust explanation of academic dishonesty and other complex organizational problems. This reconsideration of academic dishonesty occurs in the context of three American higher education institutions. I employed a variety of field methods (interviews, observations, and document analysis) in each of the four-year non-profit institutions to critically interpret the dominant way in which the problem is framed and the solutions constructed. This study identifies Integrous Individualism as the dominant framing and suggests the ways in which this framing inhibits leadership toward organizational change. Specifically I argue that in its over-simplification, the framing silences dissonant voices, trivializes the issue, leaves incongruencies unaddressed, and constrains change agency. The application of Systemic Interactionism to better understand the problem of academic dishonesty uncovers conflicting notions and competing interests co-existing within the academy to create tensions, complexity, and ambiguity. I argue that it is within this complex core that the problem is constructed and agency is mediated, and so it is this complex core that requires attention for the eventual resolution of academic dishonesty. In the end, I suggest that institutions of higher education must approach the problem of academic dishonesty not only as an issue of individual integrity but as an issue of institutional integrity. The main contributions of this research are two-fold. First, this research suggests that academic dishonesty is fundamentally a problem of unauthorized academic conduct, a tension in teaching and learning expectations caused by structural, cultural, and agentive forces. Second, the more robust framing offered in this research facilitates a complex understanding of the problem as reflexively connected to other challenges facing the institution of higher education. Ultimately, this research argues that colleges and universities must substantially alter the way in which they frame and respond to the problem

Functional and safe encapsulation of Escherichia coli in Pluronic hydrogels for engineered living materials

Bacterial growth and metabolic activity are sensitive to the mechanical properties of their environment. Understanding how the 3D spatial confinement regulates the cell behavior is crucial not only for understanding biofilm development but also for the design and safe application of engineered materials containing living cells. This Thesis explores the use of Pluronic-based hydrogels to encapsulate genetically modified Escherichia coli bacteria. Hydrogels with different viscoelastic properties were prepared by mixing Pluronic and Pluronic diacrylate components in different ratios, giving physical hydrogels with variable degree of covalent crosslinking and different mechanical responses. Rheological properties of the hydrogels as well as the growth rate and morphology of the embedded bacterial colonies were characterized. The results provided correlations between material parameters and bacterial cell responses. Further, a bilayer thin film model was developed for long term encapsulation of the organisms, preventing leakage of cells for up to two weeks while maintaining their activity as drug/protein eluting devices or biosensing units. The bacterial bilayer thin films did not elicit significant immune responses in primary immune cells from healthy donors. The results of this Thesis demonstrate the potential of Pluronic-based biohybrid as a suitable and safe prototype for further in vitro and in vivo testing of engineered living material designs.Wachstum und Stoffwechselaktivität von Bakterien sind sensitiv gegenüber den mechanischen Eigenschaften ihrer Umgebung. Das Verständnis, wie der räumliche 3D-Einschluss das Zellverhalten reguliert, ist sowohl für die Entwicklung von Biofilmen als auch für das Design und die sichere Anwendung von technischen Materialien, die lebende Zellen enthalten, essenziell. Diese Thesis untersucht die Verwendung von Hydrogelen auf Pluronic-Basis zur Verkapselung von genetisch veränderten Escherichia coli Bakterien. Durch die Mischung von Pluronic und Pluronic-Diacrylat in verschiedenen Verhältnissen wurden physische Hydrogele mit unterschiedlichem kovalenten Vernetzungsgrad und viskoelastischen Eigenschaften hergestellt. Die Charakterisierung der rheologischen Eigenschaften der Hydrogele sowie der Wachstumsrate und Morphologie der eingebetteten Bakterien zeigte eine Korrelation zwischen den Materialparametern und dem Zellverhalten. Darüber hinaus wurde ein Doppelschicht-Dünnfilmmodell entwickelt, in dem die Organismen bis zu zwei Wochen ohne Austreten eingeschlossen wurden, während gleichzeitig Medikamenten-, Proteinfreisetzung oder die Aktivität der Zellen als Biosensoren beibehalten wird. Das Modell löste bei primären Immunzellen von gesunden Spendern keine signifikanten Immunreaktionen aus. Diese Thesis zeigt das Potenzial von Biohybriden auf Pluronic-Basis als geeigneten und sicheren Prototyp für weitere in vitro und in vivo Tests von technischen lebenden Materialien
