Abstract:

Our thesis is based on the constantly changing internal and external environment causing firms to increase or decrease their internationalisation efforts. The focus of this thesis is going to be on describing the process of re-internationalisation, including the different stages of de-internationalisation, time-out, and re-entry as well as identifying the influences of the internal and external environment on the process of re-internationalisation. The influences of the internal and external environmental on the process of re-internationalisation are analysed and accompanied by secondary dat

Abstract:

This thesis presents the findings from two case study examinations of strategic performance measurement systems within two turbulent environmental contexts: the U.S. security software industry and the U.S. health care industry. Despite a three-‐decade emphasis on performance measurement research, little empirical work has been carried out inside turbulent settings—contexts characterized by rapid change, high levels of instability and complex configurations among environmental variables. This research targets that gap. Through exploratory case studies from seven security software firms paired

Abstract:

The turbulent motions of buoyant plumes and momentum jets are ubiquitous in both the natural and built environments where a stable density stratification typically persists. The fluid mechanics of turbulent plumes and jets in stratified environments encompasses a fascinating and exigent field of research motivated by an extensive range of practical applications that include low-energy building ventilation, urban air quality management and the dispersion of pollutants in natural water bodies and the atmosphere. Merely as a consequence of vertical variations in the density of the ambient fluid,

The central issue of the thesis is the innovative development of the Bick infant observation method into detailed, long term, cross-cultural video recording. Videos have been made which record individual infant development in UK, Western India, Nepal and Finland. Other observational videos demonstrate how the application of recent developmental theory can improve the care of infants in children's institutions. These are being used for teaching in over fourty countries but it is suggested that more detailed filmed records from these counties, and others, are needed. It is argued that video is i

Abstract:

Practical gas turbine engine combustors create extremely non-uniform flowfields, which are highly stratified making it imperative that similar environments are well understood. Laser diagnostics were utilized in a variety of stratified environments, which led to temperature or chemical composition gradients, to better understand autoignition, extinction, and flame stability behavior. This work ranged from laminar and steady flames to turbulent flame studies in which time resolved measurements were used. Edge flames, formed in the presence of species stratification, were studied by first develo

A projection method is deployed for solving the set of the equations, and a buoyant k-ε turbulence model is included in the numerical model. Six new advectio

This dissertation investigates how a nominally axisymmetric plume is affected by the presence of ambient turbulence. The results of this investigation are based on laboratory experiments in water. The experiments employ a saline plume released downwards into a tank of fresh water with an oscillating grid positioned near the bottom.

Buoyancy and velocity data were obtained using fluorescent dye and particle tracking, respectively. The response of a

Abstract:

A set of second-moment closure turbulence models are implemented for the study of wake evolution in an oceanic environment. The effects of density stratification are considered, and the models are validated against laboratory experiments mimicking the stratified ocean environment, and against previous experimental study of wakes subjected to a density stratification. The turbulence models are found to reproduce a number of important behaviors which differentiate stratified wakes from those in a homogeneous environment, including the appropriate decay rates in turbulence quantities, buoyant sup

Abstract:

One of the central areas of focus in organizational theory that has been of particular interest is the organization-environment interface. While various theories have made vital contributions to the study of organization-environment relations, their emphasis on organization adaptation is varied. However, research and practice have amply demonstrated that organizations do not exist in a vacuum; that if an organization is to survive and meet its goals, it has to adapt to or somehow make accommodations with its cognitive and normative environment. This study explores the issue of an organi
