The UK has pledged to reduce its greenhouse gas emissions by 80% by 2050, compared to 1990 levels. With the residential sector accounting for roughly a quarter of the UK's total carbon emissions, and with space heating accounting for roughly two thirds of residential energy consumption, addressing heating demand will prove instrumental for the UK to reach its targets. The large-scale deployment of low-carbon heating technologies, combined with signicant improvements in energy efficiency, is seen as the primary way of reducing both energy demandand carbon emissions. In this thesis, the technical potential for energy efficiency improvements in the UK's residential space heating sector is explored. Three areas of improvement are identied: the thermal performance of the building envelope, the efficiency of heating equipment, and the use of smartheating devices. In all three areas, signicant potential exists to further reduce energy demand for space heating, and the associated carbon emissions. To understand the effects of different technology adoption patterns on energy demand for spaceheating by 2050, a selectively disaggregated bottom-up model of the UK's building stock is developed. The model projects energy demand for space heating for four different technologyadoption scenarios, based on projections of future total heated oor area. In the `Minimal effort' scenario, which assumes that the least possible amount of effort is made to improve the effciency of the space heating sector, energy demand by 2050 increases slightly, by 4.3 %. In this scenario, the achieved minor effciency improvements are not able to offset the increase in the total heated oor area, leading to this small increase in space heating energydemand. In the `Efficiency focus' scenario, which assumes that signicant effort is made to improve the efficiency of the space heating sector, energy demand by 2050 decreases by 34.5 %. Despite these signicant efficiency improvements, fossil fuels still make up roughly three quarters of the fuel mix, as no major shift to cleaner energy sources has been achieved. In contrast, in the `Renewables focus' scenario, which focuses on shifting towards renewable heating options, energy demand decreases slightly less, by only 32 %, but fossil fuels make up only around 46% of the fuel mix, due to the uptake of low-carbon options such as heat pumps, district heat, and biomass. The analysis carried out in this thesis shows that the UK's residential sector consists of manyold and inefficient buildings, still heavily relies on fossil fuel-fired heating equipment, and makes nearly no use of smart heating devices to further reduce energy demand for space heating. Clearly, the technical potential for achieving energy eficiency improvements is signicant, in all three of the identified improvement areas. However, achieving the targets set forth by policymakers will require strong efforts, given the relatively bad current condition of the residential space heating sector. Existing barriers to achieving these improvements should be identifiedand addressed immediately, to ensure timely efforts are possible.

The construction industry has been plagued with an increasing number of claims and high litigation costs. How do we reduce conflict and litigation in the construction process? On one hand, leaders of the construction industry in the United States (US) focused their efforts on improving alternative dispute resolution mechanisms. For instance, the American Society of Civil Engineers has introduced the Dispute Review Board (DRB) as a complementary provision to standard US construction practices. The establishment of the DRB to solve construction disputes on the job, avoid claims, and reduce project costs has proven considerable success. On the other hand, construction industry leaders in the United Kingdom (UK) have focused some of their efforts on improving general contract conditions. The Council of the Institution of Civil Engineers of the UK has introduced the New Engineering Contract (NEC) to the construction industry as an alternative to presently used contracts. The NEC proposes to be an innovative, non-adversarial mechanism to resolve disputes on the job, avoid and reduce claims, and to assuage rising litigation costs in the construction industry. It too has proven considerable success in its efforts. This research concentrates on the DRB and the NEC as attempts by construction leaders to modernize and improve construction practices. In summary, the research compares the success stories of the DRB and the NEC as approaches to combating the adversarial nature, increasing number of disputes and rising litigation costs in the construction industry. The main conclusions ascertained in this research are as follows. Despite coming from similar business environments, construction industry leaders in the US and the UK embarked on different methods to address the issues plaguing the industry and to improve construction practices. Both in the US and the UK, construction leaders were mostly influenced to proactively seek and implement change in construction practices by experts from within the engineering and construction industry vanguard. The undertaking of these changes have shown similar success stories and the results have produced substantial impacts on the construction process. In conclusion, the efforts of construction leaders to implement the DRB and the NEC have provided effective mechanisms in improving communication and relations, and managing disputes in a timely fashion at the job site level. / Master of Science

Rainwater harvesting (RWH) can be used to reduce the demand for potable mains water. At the single-building scale, previous research has focused on water-saving potential, while financial assessment has either been omitted or considered in an ad hoc manner. This paper reports on the application of a more rigorous financial analysis of domestic RWH systems than had been conducted previously. Whole life costing was selected as the most appropriate financial assessment technique. A total of 3840 domestic system configurations were assessed at a daily time step, taking into account various stakeholder perspectives and future cost scenarios. In each case, it was found that harvesting rainwater was significantly less cost effective than relying solely on mains-only water. The domestic RWH systems generally resulted in financial losses approximately equal to their capital costs. Without significant financial support, domestic RWH is unlikely to be cost effective for all reasonably foreseeable scenarios.

With the development of multinational corporations, the United Kingdom has experienced increasing penetration of its economy by foreign affiliates. This is particularly noticeable in high technology industries such as Electrical and Instrument Engineering. The thesis identifies the mechanism by which direct foreign investment can influence industrial structure in such an industry; charts the effects within the UK Electrical and Instrument Engineering Industry; and identifies the extent to which this impact varies with the nationality of the investor. The study begins with a synthesis of the comprehensive and complex material available upon industrial/market structure and direct foreign investment. Chapters 2 and 3 demonstrate that the structure of Electrical and Instrument Engineering has changed significantly since the inter-war years. Productive capacity has expanded faster than that of any other UK industry. Throughout the minimum-list-headings of the industry market power has become more concentrated in the hands of the largest companies. Individual affiliates now display greater product specialisation and vertical integration, whilst the level of entry barriers has risen steadily. The model presented in chapter-3 hypothesises that direct foreign investment can be related to industrial structure in three distinct ways. Firstly, that a relationship exists between the distribution of foreign affiliates 11 25 I and the structural characteristics of the industries in which they operate. Secondly, that a similar relationship exists across the minimum-list-headings of each individual industry. Thirdly, that the operating characteristics of foreign affiliates in any individual minimum-list-heading differ from those of domestic companies. The first two of these are termed the Destination impact, and the third the Behavioural impact of direct foreign investment. The results of a survey of over 500 British and foreign owned companies, sub-divided by origin and size, suggest that foreign affiliates have contributed significantly to the changing structure of Electrical and Instrument Engineering both in their destination and behaviour. The destination of foreign investors was significantly related to areas displaying the fastest growth of productive capacity; imperfection of competition; technologically specialised and vertically integrated operations; and high barriers to entry. The behaviour of individual foreign affiliates was found to differ significantly from that of their UK counterparts (including affiliates of UK multinationals). Foreign owned companies exhibited high levels of sales. growth and efficiency; a disproportionate impact upon the distribution of market power; greater product specialisation and levels of vertical integration; and a significant contribution to the level of entry barriers. This influence was compounded by a greater productivity and profitability in the foreign affiliate; a differing pattern of geographical location to that of UK owned establishments; and a domestic reaction by UK companies and the government to foreign penetration. Variations within the foreign group were related to geographical origin. The total operations of US affiliates were most significant, but investors from EEC countries displayed characteristics which varied most from those of UK companies. The study concludes by relating changes in industrial structure to the presence of foreign affiliates, and outlining the implications of further foreign involvement

The thesis is divided into two parts, Part I contains four chapters which map the pattern of legal changes relating to domestic violence against women from the 18th century to the 1980s. The history is written from the viewpoint of the legal interventions available to and used by women victims of domestic violence. Statutory enactments, case law and procedural changes in the relevant areas of criminal, family (ecclesiastical) and welfare law are described. Throughout Part I the discussion of the remedies available and reforms implemented is supplemented by the inclusion of case examples and statistical evidence showing local and national patterns of use. Chapter 1 describes the period from the start of the 18th century to the begining of the 20th; Chapter 2,1900 to the 1960s, Chapter 3 from 1969 to 1977 and Chapter 4 the more recent history in the 10 years between 1977 to 1987. Part II contains five chapters and is based upon an analysis of women victim's needs in contemporary socio-legal discourse. Part II grew out of a concern about the part played by the law in the secondary assault of women. The main aim of the discussion is to look at how women victims' self defined needs inform the practice of the law and how the legal approach contributes to the creation of violent relations between men and women in the social institution of heterosexuality. Part II emphasises the use of written and spoken language in interactional settings to define women's needs. The discussion is based upon the analysis of: 1. a survey of women involved in 54 legal cases concerning their partners' behaviour supplemented by interviews with legal advisors; 2. case records obtained from solicitors' offices with the womens' permission; 3. over 300 decisions traced from the published Law Reports; 4.105 press reports of cases of domestic violence against women. Chapter 5 describes the method employed in the research for Part II. Chapter 6 contains the analysis of the women's cases; Chapter 7 the reported decisions and Chapter 8 the press reports. Chapter 9 offers a summary of academic discourse and the abuse of women as well as a concluding discussion on some possibilities for the empowerment of women in law.

Consumers have increasing choice in food products and within the social environment of today's consumer, the factors of demand are increasingly complex. Food is no longer simply a primary necessity for survival, it is a leisure and family activity, the participation in which, takes up a considerable amount of time. Today, food is a social and a political issue - something about which people have opinions, be it food quality, healthiness, or the food supply itself. It is also central to consumer's self-image. There is a large sector of the economy which supplies food demand, and this sector is itself now under considerable scrutiny from the consumer. This thesis examines consumer behaviour and attitudes towards food, with particular reference to the health aspects of food issues. It describes a programme of qualitative and quantitative research - group discussions, personal interviews and postal questionnaires. The programme examines milk (particularly low fat milk) as a diet and health case study; knowledge about food; attitudes towards food; the food industry and related issues; shopping behaviour and eating habits. It is important to both the consumer and the supplier of food, that consumer behaviour and attitudes are understood as fully as possible. This research highlights the misunderstandings between consumer and producer, emphasises the mistrust of the consumer for the producer and concludes with the need for communication between them. The thesis discusses the background to diet and health as an issue, describes the development of the current consumer environment and gives a profile of today's consumer. It then goes on to detail the research - two quantitative surveys, each undertaken over two years and a series of group discussions. The final section summarises the findings of each individual piece of the programme as a whole for various groups: food Oroducers; food manufacturers; food retailers; advertisers; the media; health professionals; the consumer; consumer organisations and government.

The major aims of this research are to explore and analyse the different factors affecting the adoption of Electronic Marketing (E-Marketing) by industrial and trading small business enterprises (SBEs); to explore the different forms, implementation levels and tools of E-Marketing used by these SBE and to investigate the relationship between E-Marketing adoption and industrial and trading SBEs marketing performance. It aims to develop a theoretical model that can help to understand and interpret these relationships and seeks to evaluate the potential of E-Marketing for SBEs in developed countries (UK) and developing countries (Egypt). This work builds on previous research in the fields of E-marketing and SBEs and adds to the relatively limited empirical research that has been conducted on E-Marketing in a small business context. This research develops and validates a conceptual model based on systematic and in-depth analysis of the literature in the field as well as the results of two exploratory studies conducted in Egypt and UK. It utilises a post-positivist research philosophy with a triangulation approach, in which quantitative and qualitative data is collected based on survey strategy through questionnaires, focus group and semi-structured interviews to address different levels of the study. Even though triangulation requires a commitment to greater amounts of effort, time and funds, it has the advantage of removing the bias that is often associated with the use of a single technique. This research finds that E-Marketing adoption by SBEs is significantly affected by their perception of E-Marketing relative advantage (usefulness), ease of use, compatibility as well as the SBE internal factors such as owner skills and support, available resources, organisational culture, type of products, international orientation and SBE size. On the other hand, the SBE internal factors have a positive direct impact on Technology Acceptance Model (TAM) and Innovation Diffusion Theory (IDT) related factors such as perceived ease of use, perceived relative advantage and perceived compatibility. These findings indicate that Internet Marketing and E-Mail Marketing are the most commonly used E-Marketing tools and that E-Marketing adoption has a strong positive impact on current and future marketing performance of SBEs. In terms of contribution to knowledge, this study provides an insight for entrepreneurs, policy makers, practitioners, researchers, and educators by providing a clearer view and deep understanding of the issues related to E-Marketing adoption and practices by small business enterprises as opposed to large companies. It addresses some research gaps in the field, particularly in terms of the impact of E-Marketing on marketing performance. The research model has been tested by a major survey of UK SBEs with a response rate of 32%, and has been robustly tested for reliability and validity. Moreover, the exploratory survey in Egypt indicated that there is another rich seam for investigation in terms of E-Marketing in developing countries. Overall the theory in the field of E-Marketing is still in its infancy stage and is not yet well established. This study can be considered as a step towards theory building in the field of E-marketing and has brought to light a number of concepts for the practice of E-Marketing by SBEs.

This study examines the intellectual capital (IC) disclosure practices in the annual reports of 100 listed UK firms selected from sectors considered to be IC-intensive. It also investigates the possible determinants of such disclosure practices from the three perspectives of corporate governance structure, company characteristics and market factors. IC disclosures were captured using content analysis, and were measured by a disclosure index, supported by word count and percentage of word count metrics to assess the variety, volume and focus of IC disclosure respectively, at both overall and subcategory levels. The presentational formats and locations of IC disclosures were also recorded. The results indicate that the UK firms sampled provide considerable IC information in their annual reports, mainly in text form, with popular use of numerical information, while the use of graphs and pictures for many IC elements remains low. The distribution of IC disclosures, captured in three categories, varies by the three measures of disclosure applied. IC information was found in virtually all sections of the annual report and was most concentrated in the Operating and Financial Review section. IC terms typically used in the academic literature do not feature in the sampled annual reports. The results of the statistical analyses based on the three measures of IC disclosure indicate significant associations with a number of corporate governance factors (i.e. board composition, share concentration, audit committee size and frequency of meeting, board directors¿ shareholding, audit committee directors¿ shareholding, and board directors with cross-directorships), company characteristics (i.e. firm size, profitability, and listing age), and market factors (i.e. `hidden value¿, share price volatility, share turnover, and multiple listing). These findings offer support for a number of theories, such as information asymmetry, agency and signalling theory. The influence of these explanatory factors on human, structural and relational capital disclosures, based on all three disclosure measure metrics, as well as on the format of IC disclosure, was also explored. The study also finds that its IC framework is more effective than a less detailed framework used in prior studies for the purpose of examining IC disclosure practice and its determinants. The study contributes to the further advancement of the state of knowledge in relation to IC disclosure both empirically and methodologically. It provides information users, preparers, regulatory bodies and academics with a state-of-the-art understanding of IC disclosure practices in the annual report. The transparent content analysis process enables future replication and comparison of results. The rigorous measurements of IC disclosure, the greater specificity of disclosure about the location and presentational format, and the more detailed IC research framework can be usefully applied by other studies. By examining the relationship between explanatory factors and IC disclosure, it helps shareholders and other groups of information users as well as the regulatory bodies to identify factors that may encourage IC disclosure in the annual report.

Chenopodium album is considered one of the most important weeds adversely affecting agricultural production due to its highly competitive influence on field crops. Chemical herbicides have increased the efficiency of farming, but recently problems of herbicideresistant weed populations and herbicide residues in soil, water, food products and effects on non-target organisms have increased, consequently, other methods of control of weeds by using specific fungi as herbicides have been suggested. The purpose of this research was to evaluate the biological control of the weed Chenopodium album by the fungus Ascochyta caulina. Some of the factors which control dormancy and germination of Chenopodium album seeds have been investigated to understand better the weed population dynamics. The results showed that seeds from two populations (UK and Libya) differ in their response to factors such as light, chilling, and burying in soil. This could have implications for effective control of the weed in different regions. Two formulations of mycoherbicides (Tween 80 and Gelatine based applications) were tested in the laboratory, and showed promise in reducing growth of the weed, especially the formula of Tween 80. There was extensive shoot fresh and dry weight reduction of inoculated Chenopodium album, as well as reduced root growth. Highest disease severity rates were observed on plants in the first three week of life. A field trial revealed similar results but less disease severity was observed, possibly because of dry weather. However, it was concluded that the fungus Ascochyta caulina is a potentially useful biological control agent but many factors still can be modified in relation to application of the mycoherbicide to increase its efficacy. / Libyan Government
