Because of a chemical disparity between Archaeal and Bacterial membrane-lipids, these organisms thrive under distinct environmental conditions. Archaea are generally more resistant to extreme habitats like low pH, high temperature or presence of solvents. It has therefore long been hypothesized that the archaeal lipids provide archaeal cells with a higher robustness than bacterial lipids do for Bacteria. A recent study in which bacterial and archaeal lipids were mixed to form hybrid vesicles “lipid enclosed round structures”, for instance showed a higher temperature dependent stability than either the bacterial or archaeal lipid vesicles separately. In the present study, we therefore introduced the enzymatic machinery for assembly of archaeal lipids into the bacterium Escherichia coli. This engineering led to cells with a mixed membrane at a surprisingly high amount of 28% archaeal lipids. Although the intervention led to severe morphological malformations, the cells indeed showed an increased robustness to extreme cold and butanol.

Thesis title: Greening production and consumption: The case of the appliance and dairy industries in Thailand

This research looked into the greening of the appliance and dairy industries in globalizing Thailand from a product chain perspective. It studied roles and strategies of appliance and dairy companies in greening consumption with an explicit involvement of consumers. This research finds that appliance and diary have increasingly attempted to engage Thai consumers in buying and using more sustainable products. To do so, companies employ different consumer-oriented strategies, including providing environmental information; however, they do not yet have a full-fledged consumer-oriented strategy to activate and engage (silent green) consumers. The study summarizes that appliance and diary companies in Thailand can advance their consumer-oriented strategies for better engaging Thai consumers (with green products and green markets) by acknowledging the role of consumers as citizens, recognizing emerging sustainable practices and lifestyles of citizens, and organizing consumer groups.

Keywords: model structure, uncertainty, modularity, software design patterns, good modelling practices, crop growth and development.

This thesis is an account of the development and use of a framework to introduce flexibility in crop modelling. The construction of such a framework is supported by two main beams: the implementation and the modelling beam. Since the beginning of the 1990s, the implementation beam has gained increasing attention in the crop modelling field, notably with the development of APSIM (Agricultural Production Systems sIMulator) in Australia, OMS (Object Modelling System) in the United States, and APES (Agricultural Production and Externalities Simulator) in Europe. The main focus of this thesis is on the modelling beam and how to combine it with the implementation beam. I first explain how flexibility is adopted in crop modelling and what is required for the implementation beam of the framework, namely libraries of modules representing the basic crop growth and development processes and of crop models (i.e. modelling solutions). Then, I define how to deal with this flexibility (i.e. modelling beam) and more specifically I describe systematic approaches to facilitate the selection of the appropriate model structure (i.e. a combination of modules) for a specific simulation objective. While developing the framework, I stress the need for better documentation of the underlying assumptions of the modules and of the criteria applied in the selection of these modules for a particular simulation objective. Such documentation should help to point out the sources of uncertainties associated with the development of crop models and to reinforce the role of the crop modeller as an intermediary between the software engineer, coding the modules, and the end users, using the model for a specific objective. Finally, I draw conclusions for the prospects of such a framework in the crop modelling field. I see its main contribution to (i) a better understanding in crop physiology through easier testing of alternatives hypotheses, and (ii) integrated studies by facilitating model reuse.

This study is about understanding how the government policy actually works at firm level in the context of developing countries' industrialization. In the literature, the discussions on impact of government policy on corporate performance primarily stress on macroeconomic aspects of industrial behavior and broad measures of industrial performance. They offer inadequate understanding of the mechanisms through which firms' performance is affected. This study attempts to fill in this void. It specifically endeavours to answer the research question: how Industrial policy affects performance of the firms? For empirical evidence, we considered the case of CNC Machine Tool industry in India. The study is primarily exploratory and qualitative based on case studies. The study endeavors to explain the policy-performance causation placing resources of the firms at the center of analysis. The three elements of the causality chain: policy, resource and performance are the building blocks of our analysis. The policy is seen in terms of technology, investment, education and training, market development and industrial governance. The resource is segmented as research, development and engineering; manufacturing; human; marketing and linkage. All these are further elaborated in terms of three more constructs: capability, mechanism and indicator. We analysed how the firms adopted various mechanisms to leverage the policies in force to build different capabilities that finally culminate in firms' performance. In certain cases the mechanisms were adopted to compensate the absence of policy or lessen its adverse impact. The promotional nature of Technology- and Investment policy as well as increased transparency in industrial governance since 1991, led the firms to emphasize more on mechanisms of assimilation of technology, new product development and subcontracting to build product development- and manufacturing capability that culminated in increased sales and exports. In the absence of suitable Education and Training policy the firms recruited educated persons, imparted in-plant training and periodic training to build human resource capability that increased firms' labour productivity. The observed divergence in firms' performance is attributed to variations in scope and implementation of mechanisms by the firms. A few pro-active firms identified what policy provides and how best that could be used or what policy does not provide and acted accordingly. The small firms appear to give less emphasis on adoption of mechanisms primarily due to resource constraints. The analyses further led to the identification of certain activities or `processes` that are found to be crucial for building various capabilities in the firms. A process encompasses one or more mechanisms either in its essence or in totality. It may also be an underlying factor that triggers mechanisms to work individually or together. The processes are visualised as acquisition, integration, development and generation. Their identification has added another bead in the strand of policy-performance causation. Like the mechanisms, the adoption of processes by the firms is also influenced by various policies in vogue that finally culminates in firms' performance. Thus the government needs to give proper emphasis on strengthening of these processes for sustained development of an industry. From the policy perspective, this research is an attempt to provide a systematic analysis that improves policy-making.
