Companies are increasingly motivated to deal with the issue of sustainability not just from a moral standpoint, but also because these issues may be a major root of innovation. To achieve these sustainable innovations, the number of manufacturers who invest in specific resources has been increasing. Supplier contributions to manufacturing company sustainable innovations are influenced by particular investments and specially the human capital investments, which emphasizes the supplier's role in supporting the producer with sustainable innovations. The precise investments might help suppliers contribute to sustainable innovation. However, if a company invests too much in certain resources, such as human capital, the beneficial impacts of such investments may diminish, and the supplier's participation in sustainable innovation may be hampered. Various internal contingency variables can moderate the relationship between the specific investments and sustainable innovation contribution of suppliers. Thus, this study aims at this research gap. This research aimed to study the relationship between human capital specific investments and supplier sustainable innovation contribution in developed markets considering the role of learning and absorptive capacity, and market orientation. This research can be considered as the deductive, quantitative and field research in which the researchers collected the primary data by using a structured questionnaire. The validity and reliability of the questionnaire confirmed through different quantitative and qualitative approaches. The research sample was chosen by using the convenience sampling. In order to respond to the questionnaire surveys, top- and middle-level managers from 355 Swedish corporations in which suppliers have been incorporated in the corporation’s sustainable innovation activities addressed. Finally, A total of 960 questionnaires for 355 companies handed out, and 102 being returned and analysed. The regression curve estimation method revealed that there is a linear relationship between human capital specific investments and supplier sustainable innovation contribution. Besides, through the hierarchical multiple linear regression, the researchers demonstrated that absorptive capacity and market orientation can play the moderating role in this relationship, while the learning capacity can partially play such role in this relationship. Eventually, the theoretical, managerial and sustainability implications discussed and the limitations of the research in addition to the future research possibilities addressed.

The broad objective of this thesis is to develop an understanding of factors affecting outsourcing in the hotel industry and also the role played by management accounting in hotel outsourcing. The thesis draws on transaction cost economics (TCE), agency, contingency, and labour process theories in the context of appraising factors motivating outsourcing. Two empirical phases have been undertaken in the study. The first phase involved a series of interviews with general managers and financial controllers in large South East Queensland hotels. The second phase involved two distinct questionnaire surveys of large Australian hotels. The first was administered to hotel general managers, and the second was administered to hotel financial controllers. Significant findings arising from the study include: 1. In light of the substantial international literature describing hotel outsourcing, it appears that outsourcing in Australian hotels is relatively limited. This appears to be particularly the case with respect to food and beverage related activities. 2. Mixed support is offered for the TCE model. Both the survey and interview data provide some support for TCE's prescription that frequently conducted activities will not tend to be outsourced. Two specific extensions are offered to this aspect of the model, however. Firstly, where activities are conducted to a minimal extent, it can be uneconomic to outsource. Secondly, where large activities are undertaken by a group of organisations, their enhanced purchasing power can result in inexpensive outsourcing arrangements. With respect to TCE's uncertainty proposition, support is offered for the view that the propensity to outsource will be greater where behavioural uncertainty is lower. No support has been offered with respect to environmental uncertainty. The interview data provides some support for TCE's asset specificity proposition, however, minimal support was found in the survey phase. Despite this, the many dimensions of asset specificity (eg. site specificity, human asset specificity, etc) provided a useful checklist of issues to be considered in relation to the outsourcing decision. 3. Negligible support was found for labour process theory (LPT) in the interview phase of the study. In light of this, and the need to narrow the study’s focus in the survey phase, LPT was not pursued further. LPT is a difficult construct to operationalise, given the social desirability error that may result. This may partially account for the absence of significant LPT findings in the interview phase. 4. The survey data provides some support for the agency theory view that risky activities will tend to be outsourced. 5. Considerable cross-hotel variation exists in management of, and accounting's involvement in, outsourcing decision making and control systems. Accounting appraisal of outsourcing proposals rarely includes long term oriented, sophisticated techniques such as "net present value". It appears this may be because outsourcing decisions are not conducted in the context of the formal capital budgeting process. 6. High performing hotels and hotels that conduct their outsourcing decisions in the context of a long term outsourcing strategic agenda have more sophisticated outsourcing management systems.

<p>Soil bottles and soil slurry experiments were conducted to investigate the effect of some additives on the aerobic and anaerobic biodegradation of chlorinated aliphatic hydrocarbons; tetrachloroethylene (PCE), trichloroethylene (TCE) and dichloroethylene (DCE) in a contaminated soil from Startvätten AB Linköping Sweden. For the aerobic degradation study the soil sample was divided into two groups, one was fertilised. The two groups of soil in the experimental bottles were treated to varying amount of methane in pairs. DCE and TCE were added to all samples while PCE was found in the contaminated soil. Both aerobic and anaerobic experiments were conducted. For aerobic study air was added to all bottles to serve as electron acceptor (oxygen). It was observed that all the samples showed a very small amount of methane consumption while the fertilised soil samples showed more oxygen consumption. For the chlorinated compounds the expected degradation could not be ascertained since the control and experimental set up were more or less the same.</p><p>For the anaerobic biodegradation study soil slurry was made with different media i.e. basic mineral medium (BM), BM and an organic compound (lactate), water and sulphide, phosphate buffer and sulphide and phosphate buffer, sulphide and ammonia. To assure anaerobic conditions, the headspace in the experimental bottles was changed to N2/CO2. As for the aerobic study all the samples were added DCE and TCE while PCE was found in the contaminated soil. The sample without the soil i.e. the control was also given PCE. It was observed that there was no clear decrease in the GC peak area of the pollutants in the different media. The decrease in GC peak area of the pollutants could not be seen, this may be so because more susceptible microorganisms are required, stringent addition of nutrients and to lower the risk of the high concentration of PCE and petroleum products in the soil from Startvätten AB.</p>

In this thesis, theoretical investigation of nickel-like tin plasma is presented. X-ray production in a plasma medium produced by a laser beam is reviewed. Applications mostly, lithography are discussed. Two different schemes for x-ray lasing, namely, quasi-steady state and transient collisional excitation are explained and compared. The computer codes that are used for plasma, especially for laser produced plasma and x-ray laser including hydrodynamic codes, ray-trace codes and collisional radiative codes are discussed. The code used in this work, EHYBRID, is considered in more detail. An experimental setup which can allow x-ray lasing is designed for different plasma and laser parameters are analyzed by means of EHYBRID code. Results are briefly discussed and as a future work the realization of the related experiment is mentioned.

Water pollution is a major concern in vast countries such as India and other developing nations. Several methods of water purification have been practiced since many decades, Semiconductor photocatalysis is a promising technique, for photodegradation of various hazardous chemicals that are encountered in waste waters. The great significance of this technique is that, it can degrade (detoxify) various complex organic chemicals, which has not been addressed by several other methods of purification. This unique advantage made this field of research to attract many investigators particularly in latter eighties and after. This thesis incorporates the studies on the various semiconductor photocatalysts that have been employed for the detoxification purposes. The fundamental principles involved in the photoelectrochemistry, reactions at the interface (solid - liquid or solid - gas) and photocatalytic reactions on fine particles are briefed. General nature and size quantization in semiconductor particles, photocatalytically active semiconductors, TiCh and ABO3 systems, chemical systems and modifications for solar energy conversions are brought out in the introduction chapter besides giving brief description about photocatalytic mineralization of water pollutants with mechanism involved, formation of reactive species and the factors influencing photomineralization reactions. Scope of the present work is given at the end of the first chapter. Second chapter deals with the materials used for the preparation of photocatalyst, preparative techniques, methods of analysis, instruments employed for the photodegradation experiments and a brief description of material characterization methods such as X-ray diffraction, transmission electron microscopy, thermogravimetric analysis, differential thermal analysis, optical absorption spectro photometry, Electron paramagnetic resonance (EPR), and gas chromatograph - mass spectroscopy (GC - MS). Various preparative routes such as wet chemical and hydrothermal methods for obtaining TiO2 (both rutile and anatase forms), BaTiOs and SrTiO3 fine particles and the chemical analysis of their constituents have been described in brief. Third chapter presents the results of materials characterization. T1O2 (rutile and anatase), BaTiO3 and SrTiO3 have been characterized separately using various techniques. Different routes of obtaining the photocatalyst fine particles, heat treatment at various temperature ranges, experimental procedures and the results of characterization are brought out in this chapter. Fourth and fifth chapters present the details of degradation studies carried out on the photomineralization of chlorophenol, trichloroethylene and formaldehyde. Studies include photodegradation of the pollutants with different catalysts varying experimental conditions to check the effects of change in concentration of pollutants, oxidizer, pH, surface hydroxylation, etc. The most favorable conditions for the complete mineralization of the pollutants have been studied. In case of TiO2, anatase form has shown greater photoactivity when compared to rutile and complete mineralization of chlorophenols has been achieved at low pollutant concentrations, neutral pH, with H2O2 and UV illumination. Retarding effects of surface hydroxylation and the formation of peroxotitanium species during photodegradation have been presented. TCE and HCHO degradation with BaTiO3/SrTiO3 has been studied. Photocatalyst heat-treated at 1100°G-1300°C is found to be highly active in combination with H2O2 as electron scavenger. HCHO is not getting degraded to its completeness in aqueous conditions owing to the strong competition in surface adsorption posed by H2O molecules. Vapour-solid phase reaction however gave good results in the detoxification of HCHO via disproportionation. Summary and conclusions are given at the end of the thesis.
