The Atlantic halibut (Hippoglossus hippoglossus) was selected as a new aquaculture candidate towards diversification from salmonid culture. The species was chosen because of its high market value and perceived good growth in the cold waters of the target farming regions. Extensive and collaborative research efforts formed the basis for the culture of this benthic marine species. Broodstock populations were established from a limited number of wild individuals due to the high costs involved in their capture. First generation hatchery reared offspring are now being selected as replacements but with no knowledge of a broodstock replacement strategy to manage this valuable genetic resource and to maximize the potential of this species the industry runs the risk of genetic degradation with the associated problems of inbreeding depression. This thesis investigates the processes involved with developing a genetic management strategy, using genetic profile technology, based on a population in Scotland at Otter Ferry Seafish Ltd. The level of genetic variability of 70 individuals in the parental population and 802 of their offspring (F1) in two year classes (1995 and 1998) was assessed at 7 microsatellite loci. The parental population which was comprised of three different stocks was genetically diverse, however, when compared with their offspring, substantial reductions in genetic variation, as judged by allelic diversity, were observed. The parentage of these F1 individuals was determined by exclusion principles and 91% of all the offspring genotyped were unambiguously assigned to a single parental pair. The assignment revealed that only half of the parents succeeded in contributing to the F1 generation. This problem was compounded by the fact that the family sizes were highly skewed such that the entire population consisted of a small number of large families resulting in an unacceptably low effective population size of 8.11. The inbreeding coefficient in the F1 generation was 6.16% however this differed markedly between the 1995 (7.74%) and 1998 (10.64%) year classes. The repeatability of reproductive performance defined by five performance traits reflecting quantity and quality of eggs, frequency of stripping events and viability was assessed by REML using data collected over three spawning seasons from 239 F1 females. The phenotypic correlations obtained between quality and quantity traits were low in magnitude and the study showed that with the exception of seasonal activity, all traits studied improved with age. There was also an effect of photoperiod in that fish kept under a 4 month-delayed regime did not perform as well as the fish under a one-month extended regime. Of all five traits, only volume of eggs collected was repeatable (r=0.37±0.07). This suggests that it is the only reproductive character influenced by the fish and all other traits, especially those pertaining to egg quality are determined by management practices. The heritability of body weight at four stages in the growout phase of production was estimated by REML using data from 486 F1 individuals. These animals were reared in two different sites, a land based tank and a sea cage. Significant effects of site, sex and grade were observed and by the end of the trial the average weight of fish in land based system was higher by 2 kg. Females were over 3 kg heavier than males and this difference was attributed to precocious maturation while fish in the smaller grade were consistently though decreasingly lighter than their larger counterparts. Heritabilities, derived from sire, dam and combined estimates ranged from 0.09 to 0.53 with wide confidence intervals. The poor precision of the estimates was due to the highly imbalanced family structure and the small number of offspring studied. Values varied depending on the age of fish and the source of variance used to estimate them. Heritabilities increased with age and although sire estimates were higher than dam estimates these differences were tested and the results obtained consistent with the conclusion that they represent nothing more than chance. The results suggested that selection for increased body weight in the halibut was likely to be successful. Based on the findings of the study a genetic management strategy for the Atlantic halibut was proposed structured on controlling the rate of inbreeding and a theory of domestication. The need to introduce additional individuals into the population was strongly recommended.

The study examines a particular aspect of the development of athletics in Scotland. The first organised clubs for the sole purpose of purely athletic competition in the contemporary sense, were cross country clubs known as harrier clubs. Through investigation of the origins, governance and the social structure of harriers clubs, the study connects these three fundamental themes in understanding sport within broader social historical study. In this study the origins of cross country running are set within a theoretical framework which recognises the nature of the urban and rural environments which defined the sport. The sport’s early growth and governance in Scotland is set alongside the broader ideological position of the ‘amateur’. Additionally, club organisation promoted the clubs as cultural institutions. Clubs served as a focus for male sociability and elevated the status of membership of the harriers. Membership meant more than just sporting engagement; it included social and civic standing. The purpose and function therefore of early clubs extended beyond participation. This study demonstrates how membership of cross country clubs conferred upon its members a status, establishing harriers clubs as important social institutions. This research shows how social networks within sport replicated society more broadly. The significance of the contribution of cross country clubs to the development of Scottish sporting culture is therefore implicit. Harriers clubs were the epitome of the complexity of sporting engagement representing both respectability and liminal behaviour.

Leasing provides a significant source of finance across UK firms. Historically, its use has been attributed to favourable tax treatment and 'off-balance sheet' accounting, both of which have been eroded over time. The present day determinants of leasing have received limited investigation, and prior research has focused on the use of finance leases in isolation from overall corporate financing decisions. This seems inappropriate given the predominant and prolific use of operating leases (Beattie, Edwards and Goodacre, 1998), and evidence to suggest that lease and debt finance appear to be at least partial substitutes (Beattie, Goodacre and Thomson, 2000). Further, proposals issued by the Accounting Standards Board in late 1999 look set to essentially remove the current 'off-balance sheet' accounting treatment of operating leases. If accounting treatment is in any way responsible for the current use of operating leases, these proposals are likely to have a significant impact on the future role of leasing. In response, the present study. investigated both the current role of leasing in the wider context of corporate financing decisions, and its future role in light of the new proposals for lease accounting. Two separate surveys of UK quoted industrial companies were undertaken to investigate corporate financing and leasing decisions and views and opinions on lease accounting reform. Findings are based on a response of 23% (198 completed questionnaires) and 19% (91 completed questionnaires) respectively. OLS regression analysis was also employed for a sample of 159 UK quoted industrial companies, to establish the existence of an 'offbalance sheet' advantage to operating leases from a market perspective. Findings suggest that UK firms appear more likely to follow Myers' (1984) suggestion of a modified pecking order of capital structure when determining their debt, including leasing, levels. Investment nd dividend payout dictate the need for external finance, and debt including leasing is internally rather than externally constrained. On average, internal reserves followed by straight debt appear preferable to leasing. However, the benefits and costs associated with all sources of finance are likely to be considered when additional finance is required. Although tax and 'off-balance sheet' advantages to leasing remain, they do not appear to dominate the leasing decision in the current climate. Avoiding large capital outlay and cash flow considerations appear of paramount importance in the decision to lease all asset types. Findings suggest that the preference for leasing over other forms of debt is not anticipated to change in response to the new proposals for lease accounting. However, the new approach may not be without consequence. Where possible, financial statement preparers are likely to take reactionary steps to minimise balance sheet obligations. At the very least, this could involve exercising any opportunity to manipulate the new accounting treatment. It may extend to reduced investment and a decline in levels of debt financing, including leasing. Although operating lease obligations appear to be currently taken into account in the UK market's assessment of equity risk, the accuracy with which they are taken into account remains unclear. Therefore, the revaluation of securities in the wake of the new proposals becoming mandatory is not beyond the realms of possibility. The present study provides a holistic analysis of corporate financing and leasing decisions in UK firms. It provides a valuable contribution to the capital structure debate. It would seem inappropriate for future capital structure research to focus on proving alternative static trade-off and pecking order theories. Future research would benefit from a reconciliation of the two. The present study highlights the difficulties in analysing corporate financing and leasing decisions, by establishing that they are complex, multidimensional and essentially situation-specific. The present study also has important implications for policy makers. In addition to the potential economic consequences, findings appear to suggest that certain features of the new proposals fall short of developing into a high quality lease accounting standard. Further consideration by policy makers from alternative perspectives appears necessary.

Sexual maturation during commercial culture of Atlantic cod (Gadus morhua L.) represents a significant production bottleneck restricting the profitability of the industry. Such problems in other species have traditionally been addressed by artificial manipulation of photoperiod cycles, however little research exists in this field in cod. This thesis therefore investigates the interactions between artificial photoperiod manipulation, sexual maturation and somatic growth in this species. In the first experiment, populations of Atlantic cod (hatched, spring 1999) were maintained on either a simulated natural photoperiod (SNP) or continuous illumination (LL) from approximately 15 months post hatch (MPH) (July 2000) in an enclosed tank system. Growth performance was recorded monthly along with observations of reproductive activity over the subsequent 2 years (up to July 2002). At both 2 and 3 years of age the entire population raised under SNP matured and spawned, during which time mean weight reduced by 13% and 24% respectively. No spawning individuals were recorded at 2 years of age in the LL population and only 18% were observed to spawn at 3. However, observations of both changes in gonadal morphology (observed via ultrasound scanning) and a suppression in growth rate at 2 years of age in the LL population alluded to a maturation “dummy run” regulated by an endogenous clock. Despite this phenomenon, the LL treatment realised a 39% and 43% improvement in wet weight following 1 and 2 years of exposure to LL respectively. When the diel cycle of plasma melatonin was compared between the treatments in February 2001 (23MPH) the SNP population displayed an A-profile diel rhythm ranging between 20 and 50 pg/ml while the LL treatment did not display any rhythm. In the second experiment of this work, two populations of cod (hatched, spring 2001) were reared in commercial open cage systems, one of which experienced continuous additional artificial illumination between July 2002 (15MPH) and October 2003 (30MPH) provided by four, 400W submerged lighting units. Growth and maturation were assessed in both populations throughout. In March 2003 (24MPH) it was apparent that spawning individuals were present in both the SNP and LL populations though a significantly lower number of spawning individuals in the LL treatment suggested that the peak in spawning activity was delayed by about 1 to 2 months. With both populations apparently maturing at 2 years of age, there was no significant difference in weight between the populations at the end of the trial. In comparison to experiments I and IV of this work, these results would suggest that in comparison to salmonids for example, Atlantic cod appear to have a heightened sensitivity to light allowing individuals to differentiate the ambient photoperiod signal from the application of continuous artificial light. In the third experiment, 6 populations of approximately 20 tagged individuals (hatched spring 1999) were maintained, from December 2000 to July 2002, under either SNP, LL or one of four, out of season “square wave” photoperiod regimes (repeating cycles with a 12 month period, consisting of a 6 month window of LL followed by six months of short day lengths [SD, 7L:17D] which had been staggered to start over a six month period). Each individual was monitored monthly for maturation status. Out of season “square wave” photoperiods were demonstrated to successfully entrain maturation and hence significantly alter the spawning profiles in these populations. Application of LL from December 2000 failed to inhibit maturation in the spring of 2001 and, in fact, advanced the spawning season by 1 month while those that experienced SD from the same date showed significant extension of the subsequent spawning season. Interestingly, the males maintained on LL throughout the experiment matured both in the spring of 2001 and one year later in the spring of 2002 while females under the same treatment only matured and spawned in 2001. In the fourth experiment, a total of 830 tagged individuals were raised either under SNP or one of 7 photoperiod treatments, consisting of 5 groups transferred from SNP to LL at 3 monthly intervals between 6 and 18 MPH where they remained and a further two groups maintained on LL from 6 to 15MPH and 6 to 21 MPH respectively before being returned to SNP. Both the gonadic and somatic axes were monitored at the physiological and endocrinological level at three monthly intervals from 6 to 27 MPH. The results demonstrated that it is the falling autumnal photoperiod signal after the summer solstice, more specifically after October, that is responsible for recruiting individuals to enter the sexual maturation cycle. Furthermore, in all treatments where this signal was masked i.e. those which experienced LL starting at or prior to 15MPH, except for some restricted spermatogenic activity in the males testis observed at 27MPH, there was no significant reproductive activity and growth was improved by up to 60% at 27 MPH. While providing evidence for direct photic stimulation of somatic growth, the growth results were also correlated with the measurement of plasma IGF-I and demonstrated its potential as a tool to assess growth rates in the species. Plasma melatonin measured at 15MPH, as in experiment I, was suppressed in all populations which were under LL photoperiods. By identifying the photoperiod “window of opportunity” which recruits individuals into the sexual maturation cycle, this work was able to conclude that the application of LL from the summer solstice prior to maturation is the most efficient photoperiod strategy to be adopted by the aquaculture industry to realise maximum growth potential from their cultured stocks.

Managers today are faced with a bewildering choice of Management Standards that are being promoted to improve personal and organisational performance by a wide range of Standards-setting bodies. Standards-based management is a well-researched field, but all the research concentrates on individual Standards such as ISO 9000 and 14000 without identifying the influences of other Management Standards. This research seeks to extend the debate about Standards-based management and to encourage other researchers to consider it as both an entity and a phenomenon and to note its divergence from other management theories. A taxonomy of Management Standards is presented to enable the principal Standards to be categorised and a definition of a Management Standard is proposed to enable the distillation of the considerable body of literature into more manageable proportions. A chronology of Management Standards development is tabled and compared with the evolution of Quality Management and Total Quality Management (TQM) and the possible future development of Management Standards is examined. The literature research confirmed that Standards-based management approaches had increased very significantly, despite a lack of empirical research to show that this method of management yielded uniform improvements. It identified a trend for integrating Management Standards and creating a “super” Management Standard that would incorporate all the functions of management within an organisation. The Scottish Quality Management System (SQMS) is an integrated Management Standard that incorporates many of the key functions of management within an audited Management Standards framework that its architects claim is based on the principles of TQM. While originally developed for the Scottish training provider network in 1993, it has spread internationally and is currently in use by circa 600 organisations in several countries. It is the only example of a Management Standard of this kind, and despite its longevity, extensive coverage and significant public investment, it has not attracted any previous research interest. The SQMS project was ambitious, seeking to impose a major new Standard on a diverse and predominately unsophisticated population of organisations within a tight time frame. The field research surveyed the entire SQMS registered organisation population using a questionnaire that was based upon the principles of ISO 9004: 1994 and some preliminary research. The questionnaire was designed to examine attitudes and motivation, as well as gauging the effectiveness of the SQMS Standard as determined by an analysis of the improvements that could be directly associated with its implementation. The survey achieved over 70% response rate and the resulting data set was comprehensive and the analysis robust. An additional element of the research compared the results of the questionnaire response analysis with the perceptions of the SQMS Auditors who had audited a majority of the respondent organisations. The field research showed that the SQMS population was very experienced and had been working with SQMS for well over three years. This is a period that the literature research indicated was the minimum time required for the benefits of quality improvement initiatives to become measurable. In the absence of any clear published objectives for the implementation of SQMS, a number of likely objectives were postulated and these objectives were measured against the results of the research. The results of the research suggest an attitude of compliance, rather than improvement as the underlying mind-set of the SQMS organisations and an absence of quality improvement planning or measurement of key performance indicators. This attitude was no different among organisations that had also adopted ISO 9000 and IiP. SQMS accreditation had not shown to provide any marketing or promotional benefit in the same way as ISO 9000 and it had not led to increased market share or profitability. Few of the possible benefits of applying a Standard of this nature had been realised by the majority of organisations and there was little evidence of tangible organisational improvement. The Standard could not be deemed to have met its proposed objectives and a comparison with an accepted model of TQM did not find sufficient compatibility to designate SQMS as a tool for TQM implementation. The interviews with SQMS Auditors identified major discrepancies between their perceptions and the views of the organisations that they audited. The admission by over half of the respondent organisations that they produced evidence purely to satisfy audits raised questions about the effectiveness of the Standard and its audits and the competence of auditors to audit “super” Standards. The novelty of the research is examined and suggestions for future research proposed.

Home automation is maturing with the increased deployment of networks and intelligent devices in the home. Along with new protocols and devices, new software services will emerge and work together releasing the full potential of networked consumer devices. Services may include home security, climate control or entertainment. With such extensive interworking the phenomenon known as service interaction, or feature interaction, appears. The problem occurs when services interfere with one another causing unexpected or undesirable outcomes. The main goal of this work is to detect undesired interactions between devices and services while allowing positive interactions between services and devices. If the interaction is negative, the approach should be able to handle it in an appropriate way. Being able to carry out interaction detection in the home poses certain challenges. Firstly, the devices and services are provided by a number of vendors and will be using a variety of protocols. Secondly, the configuration will not be fixed, the network will change as devices join and leave. Services may also change and adapt to user needs and to devices available at runtime. The developed approach is able to work with such challenges. Since the goal of the automated home is to make life simpler for the occupant, the approach should require minimal user intervention. With the above goals, an approach was developed which tackles the problem. Whereas previous approaches solving service interaction have focused on the service, the technique presented here concentrates on the devices and their surrounds, as some interactions occur through conflicting effects on the environment. The approach introduces the concept of environmental variables. A variable may be room temperature, movement or perhaps light. Drawing inspiration from the Operating Systems domain, locks are used to control access to the devices and environmental variables. Using this technique, undesirable interactions are avoided. The inclusion of the environment is a key element of this approach as many interactions can happen indirectly, through the environment. Since the configuration of a home’s devices and services is continually changing, developing an off-line solution is not practical. Therefore, an on-line approach in the form of an interaction manager has been developed. It is the manager’s role to detect interactions. The approach was shown to work successfuly. The manager was able to successfully detect interactions and prevent negative interactions from occurring. Interactions were detected at both device and service level. The approach is flexible: it is protocol independent, services are unaware of the manager, and the manager can cope with new devices and services joining the network. Further, there is little user intervention required for the approach to operate.

This study is an in-depth empirical investigation that seeks to compare consumer expectations to perceptions in the delivery of service within community banks in the southern United States. It has as its aim to develop a useful instrument to evaluate service quality by comparing consumer expectations to their perceptions of delivered service. An additional purpose is to determine bank chief executive officers’ ability to predict consumer expectations in the area of service delivery. The theoretical portion of the study focused upon a review of the history of banking in the United States and its subunit, the State of Texas, which is uniquely different from the banking systems of Europe and Asia. The literature was also examined to review service quality and customer satisfaction. In order to examine methods to predict service quality in community banks, an investigation was carried out among consumers of fifteen community banks in the southern United States. The collection of the data was driven by six research hypotheses and involved two questionnaires. One questionnaire ask for customer expectations versus perceptions. A second questionnaire required the chief executive officers of the consumers’ banks to state their perceptions of what their consumers expected in the way of service delivery. The main findings of the research built upon and extended the research by Ittner and Larcker (1996) which noted that the three prime components of customer satisfaction revolved around three specific antecedents—perceived quality, perceived value, and customer expectations, the study strongly reinforced and confirmed the importance of the three antecedents. This study indicated that while expectations are very high, perceptions are also high, but not as high as expectations. Milligan (1995) advanced the idea that it should be obvious that the element of service quality was the primary driver in bank selection, but no confirmation study was made by him or others comparing the five factors (service quality, location, advertising, recommendation of others, and service charges/fees). This study concluded that service quality was the most important factor in the selection of a community bank in the southern United States. With no specific literature relating specifically to bankers’ perceptions of service delivery expectations by consumers, one of the most significant findings in this study noted that 77.3 percent of the responses to the questions indicated a match of bankers’ perceptions with consumers’ expectations. While outcomes indicated that perceptions were equal to or greater than expectations, this does not conclusively prove that satisfactory service quality will tend to be associated with outcomes equal to or above expectations. This could indicate that the customers did not expect much in the way of outstanding service. Based upon results obtained from surveys, there appears to be a high likelihood that a bank could reasonably predict the retention of customers using the overlaid plots that in this study show high expectations and high perceptions. However, this study could not conclusively substantiate that gender, income, and education impact service quality in community banks. Given the limited amount of literature relating to the delivery of service quality by community banks in the United States, this study provides both researchers and practitioners an empirical study of both consumers’ and bankers’ expectations and perceptions of service delivery, which had not been fully explored in the past.

This thesis argues that pluralism and diversity pose a more fundamental challenge to liberal constitutionalism than is sometimes recognised by liberal political theorists. While the challenges presented by moral pluralism at the philosophical level, and by cultural diversity at the socio-cultural level, have received a great deal of attention in recent political thought, the background within which these themes become salient has not always been fully acknowledged. What is new in the modern world is not so much diversity of lifestyles, but the disintegration of frameworks that traditionally provided an unproblematic basis for political authority. What this modern challenge forces us to confront then, is the idea that ‘the people’ who are subject to law, are also, as citizens, the ultimate source of political authority. I consider in detail the work of two contemporary political theorists who have provided among the most sustained and far-reaching attempts to respond to this challenge, Charles Taylor and Jürgen Habermas. Both make a significant contribution to responding to the contemporary situation of pluralism by taking on board the ‘dialogical’ nature of identity, and the role of the ‘people’ as the ultimate source of political power. However each places a heavy reliance on a privileged standpoint that may shield political judgement from the full implications of modern pluralism: Habermas, by appealing to ‘post-conventional morality’ and Taylor, by appealing to an incipient teleology.

This thesis has two main objectives. First, it accomplishes a detailed critical reading of Michel Foucault’s writings on the archaeology of knowledge, focusing on the emergence of political economy. Second, it explores some possibilities opened up by his work for a rethinking of the historiography and methodology of economics. The first results from the fact that there have been very few assessments of his archaeology of economics, not only in economics itself, but also in the fields of philosophy and history of thought in general. Although it may be possible to find some applications in economics of notions and concepts introduced by him, this has mostly been done without a detailed critical analysis of his writings. Thus, it is considered here that it is first necessary to go back to his writings and to develop a very careful reading of them in order to be able to explore them in a second stage. As for the second, the main argument is that his archaeology has important contributions that are still missing by economists. The study is developed in two parts. The first part is dedicated to a meticulous reading of the The Archaeology of Knowledge and The Order of Things, ending up with an assessment. Part II develops an analysis of his contributions in three areas of research in economics: methodology of economics, historiography of economic thought, and studies on Adam Smith’s context. This analysis is considered itself an important contribution of this thesis. Chapter 3 situates Foucault’s perspective and system among other current interests in economic methodology, comprising basically three parts. First, it identifies one common fundamental question underlying some of these interests, that is, whether there is an underlying configuration in knowledge that permits us to think what we think in economics in a certain moment in time and space. It is argued that Foucault’s archaeology makes important contributions to this strand. Second, it compares his approach to the current interest in rhetorical studies in economics. Third, it gives special attention to the historiography of economic thought through the investigation of the interplay between the notion of the ‘episteme’ and the Kuhnian concept of ‘paradigm’. Chapter 4 explores and assesses his archaeology of political economy in The Order of Things and briefly indicates some of the important ideas provided by him in his lectures at the Collège de France in 1978-79, which give some hints for the possibility of investigating the current epistemic context underlying economics. The last chapter concentrates on Smith’s writings on language and rhetoric, the methodological conception underlying his writings, and the notion of invisible hand, according to Foucault’s system. This latter essentially shows the potentiality for his system to improve the level of consciousness of our past and emphasizes that it opens up a series of possibilities of further and interesting inquiries. The thesis concludes with an appraisal of Foucault’s contribution and additional issues for further enquiry.

This study examines how working women are represented in the news media, and its main aim is to determine to what extent ‘social class’ figures in the representations of women in news content. Using language, visual and narrative analysis, the thesis comprises four case studies each focusing on portrayals of different women from different socio-economic backgrounds determined by their occupation. The first two case studies examine portrayals of low paid working women through coverage of the National Minimum Wage introduction into Britain in April 1999 and the Council Workers’ Strike in England and Wales in 2002. The latter two case studies focus on women in particular professions: elite businesswomen, military women and women war reporters. The study concludes by noting that multiple voices occur in news texts around the key contrasting themes of progress/stagnation and visibility/invisibility and which can give contradictory discourses on the intersection of gender and class. From the massification and silencing of working class women, to the celebrity and sexualisation of the business elite, and the professional competency news frames of middle class women, class was shown to be a determining factor in how women figure in news content. However, these class determinants combined with other news frames pertaining to gender, whereby powerful and established myths of femininity can come to the fore. These myths can be particularly powerful when women enter non-feminine work ‘spaces’ such as business and the military, and class, particularly in the latter case, can tend to slip out of view, as sexist coverage is commonplace and debates are formed about the right and wrong behaviour for women.
