Ethical climates and ethical behavior
The relationship between five ethical climates -- caring, service, law and code, independence, and instrumentalism -- and four behaviors -- lying, stealing, failure to follow orders, and being an accomplice to a crime -- was tested in a multi-unit, commissioned sales, organization. Drawing …

Model development for urban climates
Cities face pressing challenges from rapidly growing populations, a warming global climate, air pollution, resource depletion and energy scarcity. Computational models can assist in understanding interactions and planning solutions. This thesis documents a series of developments intended to improve …

Sterile neutrinos in cold climates
Measurements of neutrino oscillations at short baselines contain an intriguing set of experimental anomalies that may be suggestive of new physics such as the existence of sterile neutrinos. This three-part thesis presents research directed towards understanding these anomalies and searching for …

Species response to shifting and variable climates
Evidence has been accumulating that suggests some arcto-boreal plant taxa persisted through the Last Glacial Maximum (LGM) in Alaska and adjacent Canada. In part, my dissertation investigated the spatial patterns of glacial persistence and postglacial colonization of an alder (Alnus) species …

Conserving Moving Species under Changing Landscapes and Climates
… to understand the dynamic landscapes and climates through which species move and how the environment influences movement choices. In particular, I am interested in how species respond to human modifications to landscapes and climates. Chapter 1 uses datasets on the spatial and temporal …

Solar induced ventilation in the Algerian and similar climates
In hot climates ventilation can be a useful means of cooling dwellings, if the outside air be cooler than that inside the dwelling. Often, in hot regions the outside air is so hot during the day that cooling by ventilation is of no benefit until the evening when the outside air gets cooler. …

Paleoenvironment reconstruction in extreme climates using organic geochemical investigations
Organic geochemistry provides researchers with an extensive suite of tools for reconstructing past environments. Using these tools, a set of unique locations situated in climatic extremes have been investigated. During the Early Cenozoic the planet was much warmer than today. In addition to this …

Biologically-inspired high-performance envelope design in tropical climates
… regions. Using the dynamic stressors of tropical climates as a source of inspiration, this work hypothesizes that the abundant latent energy found in tropical climates can be used to power discernable thermal change in unconditioned spaces. Using environmental cues to trigger non-linear events, …

Mixed-Mode Cooling Design for Office Buildings in Arid Climates
… only when strictly required. Although arid climates cover nearly a third of the earth land area, research into mixed-mode strategies has focused mostly on European applications and temperate climate zones. This research tests the performance of different mixed-mode cooling strategies for …

Ecology and climates of early Middle Pleistocene interglacials in Britain
… of these global climatic characteristics on climates and ecology at regional and local scales is yet to be fully understood. Local ecological processes, particularly disturbance processes, have also received limited attention in pre-Holocene interglacial settings, despite their likely …

A tropical grammar : an architectural grammar for hot humid climates
… responsive architecture in hot humid climates. It argues that since traditional Caribbean architecture is a successful response to the constraints of climate and resources, a grammar based on this architecture would produce designs with similar characteristics and therefore would still …

Ethical climates in lodging operations: An exploratory study of management perceptions
This study explored the role of ethics in lodging organizations. Managers working at five different properties constituted the survey sample. The study examined management perceptions as measured by the Ethical Climate Questionnaire (ECQ). This instrument, used in previous research on moral …

The impact of biochar on soil functioning in two contrasting climates
… and biological properties in two different climates at the same time. The aims of this study were to determine the effect of biochar ageing on tropical and temperate soil characteristics and also to assess the effect of different particle sizes and application rates on temperate soil …

Numerical modelling of the dynamics response of glacier to changing climates
… of different climate and represent two types of climates in the High Arctic. The two glaciers are subjected to 5 possible greenhouse scenarios with various precipitation increases. Since the glaciers are not in balance with the current climate, the results suggested that even with no further …

Low energy cooling in multi-storey buildings for hot, arid climates
… cooling strategies and systems in hot arid climates. The choice of a certain strategy, as well as determining the appropriate cooling schemes for such a context becomes of prime importance in developing the optimum energy conscious building design. The motivation for working in this area of …

On the maintenance of weak meridional temperature gradients during warm climates
This thesis examines the dynamics of equable climates. The underlying physics of two mechanisms by which weak meridional temperature gradients might be maintained are studied. First, I examine the evolution of stratospheric dynamics and winter temperatures when the surface temperature gradient and …

Identifying Dry Intrusion Outflows in Present and Future Climates with Machine Learning
Dry intrusions (DIs) are one of the key airstreams associated with extratropical cyclones. They are known to exacerbate the impacts of mid-latitude weather through mixing with the boundary layer and enhancing atmosphere-surface interactions. Currently, DIs are identified with Lagrangian trajectory …

Climates of Mutation: Posthuman Orientations in Twenty-First Century Ecological Science Fiction
Climates of Mutation contributes to the growing body of works focused on climate fiction by exploring the entangled aspects of biopolitics, posthumanism, and eco-assemblage in twenty-first-century science fiction. By tracing out each of those themes, I examine how my contemporary focal texts …

Design of a residential air source heat pump for extremely cold climates
Air source heat pumps are energy efficient systems suitable for space heating applications, however, their performance drastically degrades in low ambient temperatures. An innovative design is proposed in this thesis that can switch operating modes to allow efficient heating operation in an ambient …
