Parallel relationships, architecture and water : the urban spa

This thesis explores the relationship of architecture and water through the design of an urban spa that offers both a bodily and a poetic experience of water. Research included investigation of recent architectural projects that enhance and order the view, sound, and touch of water as well as projects that integrate fountains, showers and reflecting pools into the experience of a building. In the design of the spa, the movement of water was based metaphorically on the natural water cycle: evaporation, condensation and collection of water in pools. The building presents fountains, rivulets, and pools in a descending sequence that represents the natural flow of water. The temperature of water and the activities of the spa follow the same descending sequence, progressing from a warm water bath at the top of the building to cool swimming pool at the plaza level in a contemporary interpretation of the experience of a Roman Bath.

Shoot architecture and growth in the south Florida wet prairie macrophyte, Eleocharis cellulosa

Eleocharis cellulosa is a dominant macrophyte in Everglades wet prairie communities. The development of the shoot system in the genus has been described as sympodial but with an unusual adnation of the horizontal and vertical shoots. The growth pattern of E. cellulosa was studied from field collected plants and plants grown in the greenhouse. Plants were extracted and measurements of horizontal and vertical shoot were taken. Dissections, paraffin sectioning and SEM's were used to examine shoot structure in early developmental stages. E. cellulosa was transplanted from the field to the greenhouse and different levels of Nitrogen and Phosphorus were added to determine how it responded phenotypically. Dissections and microscopy showed that growth of the vertical shoots of E. cellulosa is sympodial, while growth of the horizontal shoots is mixed, beginning monopodially then transforming to sympodial growth. Additions of nutrients did not have any effect on the morphology of E. cellulosa.

Architecture and health care: a place for sociology.

Sociologists of health and illness have tended to overlook the architecture and buildings used in health care. This contrasts with medical geographers who have yielded a body of work on the significance of places and spaces in the experience of health and illness. A review of sociological studies of the role of the built environment in the performance of medical practice uncovers an important vein of work, worthy of further study. Through the historically situated example of hospital architecture, this article seeks to tease out substantive and methodological issues that can inform a distinctive sociology of healthcare architecture. Contemporary healthcare buildings manifest design models developed for hotels, shopping malls and homes. These design features are congruent with neoliberal forms of subjectivity in which patients are constituted as consumers and responsibilised citizens. We conclude that an adequate sociology of healthcare architecture necessitates an appreciation of both the construction and experience of buildings, exploring the briefs and plans of their designers, and observing their everyday uses. Combining approaches and methods from the sociology of health and illness and science and technology studies offers potential for a novel research agenda that takes healthcare buildings as its substantive focus.

Archaeology, Architecture and Digital Adaptation: Developing a GIS for Archaeological Excavation on Crete

This paper is not about the history or archaeology of Priniatikos Pyrgos per se. Rather, it is a review of how the site was recorded using both traditional survey and planning techniques and digital approaches applied through a Geographical Information System (hereafter GIS) during the 2007 through 2010 seasons. Earlier work at the site will necessarily be reviewed, specifically the geophysical survey work of the Istron Geoarchaeological Project and the excavations by Hayden and Tsipopoulou between 2005 and 2006, and regional survey work by Hayden and colleagues in the Vrokastro region (Hayden, this volume, 1999, 2004; Sarris et al. 2005; Shahrukh et al. 2012). The digitisation and incorporation of the latter into the project GIS will be explored in some detail.

Seasonality Shows Evidence for Polygenic Architecture and Genetic Correlation With Schizophrenia and Bipolar Disorder

OBJECTIVE: To test common genetic variants for association with seasonality (seasonal changes in mood and behavior) and to investigate whether there are shared genetic risk factors between psychiatric disorders and seasonality. METHOD: Genome-wide association studies (GWASs) were conducted in Australian (between 1988 and 1990 and between 2010 and 2013) and Amish (between May 2010 and December 2011) samples in whom the Seasonal Pattern Assessment Questionnaire (SPAQ) had been administered, and the results were meta-analyzed in a total sample of 4,156 individuals. Genetic risk scores based on results from prior large GWAS studies of bipolar disorder, major depressive disorder (MDD), and schizophrenia were calculated to test for overlap in risk between psychiatric disorders and seasonality. RESULTS: The most significant association was with rs11825064 (P = 1.7 × 10⁻⁶, β = 0.64, standard error = 0.13), an intergenic single nucleotide polymorphism (SNP) found on chromosome 11. The evidence for overlap in risk factors was strongest for schizophrenia and seasonality, with the schizophrenia genetic profile scores explaining 3% of the variance in log-transformed global seasonality scores. Bipolar disorder genetic profile scores were also associated with seasonality, although at much weaker levels (minimum P value = 3.4 × 10⁻³), and no evidence for overlap in risk was detected between MDD and seasonality. CONCLUSIONS: Common SNPs of large effect most likely do not exist for seasonality in the populations examined. As expected, there were overlapping genetic risk factors for bipolar disorder (but not MDD) with seasonality. Unexpectedly, the risk for schizophrenia and seasonality had the largest overlap, an unprecedented finding that requires replication in other populations and has potential clinical implications considering overlapping cognitive deficits in seasonal affective disorders and schizophrenia.

Safety and complexity: the inter-departmental threats to patient safety in the operating department

Purpose: Current thinking about ‘patient safety’ emphasises the causal relationship between the work environment and the delivery of clinical care. This research draws on the theory of Normal Accidents to extend this analysis and better understand the ‘organisational factors’ that threaten safety. Methods: Ethnographic research methods were used, with observations of the operating department setting for 18 month and interviews with 80 members of hospital staff. The setting for the study was the Operating Department of a large teaching hospital in the North-West of England. Results: The work of the operating department is determined by inter-dependant, ‘tightly coupled’ organisational relationships between hospital departments based upon the timely exchange of information, services and resources required for the delivery of care. Failures within these processes, manifest as ‘breakdowns’ within inter-departmental relationships lead to situations of constraint, rapid change and uncertainty in the work of the operating department that require staff to break with established routines and work with increased time and emotional pressures. This means that staff focus on working quickly, as opposed to working safely. Conclusion: Analysis of safety needs to move beyond a focus on the immediate work environment and individual practice, to consider the more complex and deeply structured organisational systems of hospital activity. For departmental managers the scope for service planning to control for safety may be limited as the structured ‘real world’ situation of service delivery is shaped by inter-department and organisational factors that are perhaps beyond the scope of departmental management.

The Effect of Architecture and Shear Stress on Endothelialization of 3D Printed Vascular Networks

Despite significant progress in the field of tissue engineering within the last decade, a number of unsolved problems still remain. One of the most relevant issues is the lack of proper vascularization that limits the size of engineered tissues to smaller than clinically relevant dimensions. In particular, the growth of engineered tissue in vitro within bioreactors is plagued with this challenge. Specifically, the tubular perfusion system bioreactor has been used for large scale bone constructs; however these engineered constructs lack inherent vasculature and quickly develop a hypoxic core, where no nutrient exchange can occur, thus leading to cell death. Through the use of 3D printed vascular templates in conjunction with a tubular perfusion system bioreactor, we attempt to create an endothelial cell monolayer on 3D scaffolds that could potentially serve as the foundation of inherent vasculature within these engineered bone grafts.

Designing Happiness: Architecture and urban design for joy and well-being

Scientific studies exploring the environmental and experiential elements that help boost human happiness have become a significant and expanding body of work. Some urban designers, architects and planners are looking to apply this knowledge through policy decisions and design, but there is a great deal of room for further study and exploration. This paper looks at definitions of happiness and happiness measurements used in research. The paper goes on to introduce six environmental factors identified in a literature review that have design implications relating to happiness: Nature, Light, Surprise, Access, Identity, and Sociality. Architectural precedents are examined and design strategies are proposed for each factor, which are then applied to a test case site and building in Baltimore, Maryland. It is anticipated that these factors and strategies will be useful to architects, urban designers and planners as they endeavor to design positive user experiences and set city shaping policy.

Compounds, creativity and complexity in climate change communication: the case of ‘carbon indulgences’

This article deals with climate change from a linguistic perspective. Climate change is an extremely complex issue that has exercised the minds of experts and policy makers with renewed urgency in recent years. It has prompted an explosion of writing in the media, on the internet and in the domain of popular science and literature, as well as a proliferation of new compounds around the word ‘carbon’ as a hub, such as ‘carbon indulgence’, a new compound that will be studied in this article. Through a linguistic analysis of lexical and discourse formations around such ‘carbon compounds’ we aim to contribute to a broader understanding of the meaning of climate change. Lexical carbon compounds are used here as indicators for observing how human symbolic cultures change and adapt in response to environmental threats and how symbolic innovation and transmission occurs.

SAFARI optical system architecture and design concept

SpicA FAR infrared Instrument, SAFARI, is one of the instruments planned for the SPICA mission. The SPICA mission is the next great leap forward in space-based far-infrared astronomy and will study the evolution of galaxies, stars and planetary systems. SPICA will utilize a deeply cooled 2.5m-class telescope, provided by European industry, to realize zodiacal background limited performance, and high spatial resolution. The instrument SAFARI is a cryogenic grating-based point source spectrometer working in the wavelength domain 34 to 230 μm, providing spectral resolving power from 300 to at least 2000. The instrument shall provide low and high resolution spectroscopy in four spectral bands. Low Resolution mode is the native instrument mode, while the high Resolution mode is achieved by means of a Martin-Pupplet interferometer. The optical system is all-reflective and consists of three main modules; an input optics module, followed by the Band and Mode Distributing Optics and the grating Modules. The instrument utilizes Nyquist sampled filled linear arrays of very sensitive TES detectors. The work presented in this paper describes the optical design architecture and design concept compatible with the current instrument performance and volume design drivers.

Genetic architecture and sexual conflict in the life history of Drosophila

Because males and females of a species express many homologous traits, sex-specific selection on these traits can shift the opposite sex away from its phenotypic optimum. This mode of sexually antagonistic selection, known as intralocus sexual conflict (IaSC), arises when the evolution of sexual dimorphism is constrained by the two sexes sharing a common gene pool. As IaSC has been historically overlooked, many outstanding questions remain. For example, what is its contribution in maintaining genetic variation for fitness in populations? What characters underlie this variation in fitness? How does the selection history of the population influence the standing genetic variation? I used the model organism Drosophila melanogaster to attempt to resolve some of these questions. The first part of my Master’s project involved assessing the detectability of sexually antagonistic alleles in populations at different stages of adaptation to the laboratory. For the second part of my Master’s project, I looked for evidence of conflict during the development of body size, a well-known sexually dimorphic trait. While the first part of my thesis proved inconclusive, the second part revealed a surprising source of sexual conflict in pre-adult stages of D. melanogaster.

Journal of Architecture and Urbanism - Rethinking Le Corbusier: Urban Design and History

This is much more than a mere compilation of texts about Corbusian architecture. The articles gathered here focus on Le Corbusier’s reflections about the public space of earlier times and its influence upon his own output, the relationship of his designs with the pre-existing city, and other subjects drawn from all periods of his career and training that clarify the affinity that he established with the past through urban design. They are very heterogeneous, pointing off in different directions and marking the most diverse interests. But at the same time they are interconnected, in that they seek to shed light on the affinity that Le Corbusier established with the past from the point of view of urban design, and open up new perspectives about the public space in his work and its controversial relationship with history. This special issue thus bears witness once again to Le Corbusier’s inexhaustible legacy, but also to the usefulness of research on his work and thought – a subject about which it seemed that everything had already been said when, paradoxically, we now know that there is still almost everything left to say.

Moyens informatiques de restitution en archéologie monumentale : cas du temple de Karnak

L’objectif de notre recherche est l’exploration et l’étude de la question de l’instrumentation informatique des projets de reconstitution archéologiques en architecture monumentale dans le but de proposer de nouveaux moyens. La recherche a pour point de départ une question, à savoir : « Comment, et avec quels moyens informatiques, les projets de reconstitution architecturale pourraient-ils être menés en archéologie? ». Cette question a nécessité, en premier lieu, une étude des différentes approches de restitution qui ont été mises à contribution pour des projets de reconstitution archéologiques, et ceci, à ses différentes phases. Il s’agit de comprendre l’évolution des différentes méthodologies d’approche (épistémologiquement) que les acteurs de ce domaine ont adoptées afin de mettre à contribution les technologies d’information et de communication (TIC) dans le domaine du patrimoine bâti. Cette étude nous a permis de dégager deux principales avenues: une première qui vise exclusivement la « représentation » des résultats des projets et une seconde qui vise la modélisation de ce processus dans le but d’assister l’archéologue dans les différentes phases du projet. Nous démontrons que c’est la deuxième approche qui permet la combinaison et met à la disposition des archéologues une meilleure exploitation des possibilités que l’outil informatique peut et pourra présenter. Cette partie permet de démontrer la nature systémique et complexe de la mise à contribution des TICs dans le domaine de la restitution archéologique. La multitude des acteurs, des conditions techniques, culturelles et autres, des moyens utilisés ainsi que la variété des objectifs envisagés dans les projets de reconstitution archéologiques poussent à explorer une nouvelle approche qui tient compte de cette complexité. Pour atteindre notre objectif de recherche, la poursuite de l’étude de la nature de la démarche archéologique s’impose. Il s’agit de comprendre les liens et les interrelations qui s’établissent entre les différentes unités techniques et intellectuelles en jeu ainsi que les différents modes de réflexions présents dans les projets de reconstitution archéologique du patrimoine bâti. Cette étude met en évidence le rapport direct entre le caractère subjectif de la démarche avec la grande variabilité des approches et des raisonnements mis en œuvre. La recherche est alors exploratoire et propositionnelle pour confronter notamment le caractère systémique et complexe de l’expérience concrète et à travers les publications savantes, les éléments de la réalité connaissable. L’étude des raisonnements archéologiques à travers les publications savantes nous permet de proposer une première typologie de raisonnements étudiés. Chacune de ces typologies reflète une méthodologie d’approche basée sur une organisation d’actions qui peut être consignée dans un ensemble de modules de raisonnements. Cette recherche fait ressortir, des phénomènes et des processus observés, un modèle qui représente les interrelations et les interactions ainsi que les produits spécifiques de ces liaisons complexes. Ce modèle témoigne d’un processus récursif, par essais et erreurs, au cours duquel l’acteur « expérimente » successivement, en fonction des objectifs de l’entreprise et à travers des modules de raisonnements choisis, plusieurs réponses aux questions qui se posent à lui, au titre de la définition du corpus, de la description, de la structuration, de l’interprétation et de la validation des résultats, jusqu’à ce que cette dernière lui paraisse satisfaire aux objectifs de départ. Le modèle établi est validé à travers l’étude de cas du VIIème pylône du temple de Karnak en Égypte. Les résultats obtenus montrent que les modules de raisonnements représentent une solution intéressante pour assister les archéologues dans les projets de reconstitution archéologiques. Ces modules offrent une multiplicité de combinaisons des actions et avantagent ainsi une diversité d’approches et de raisonnements pouvant être mis à contribution pour ces projets tout en maintenant la nature évolutive du système global.
