Skucha, Julie Mary. "Mature female graduates : moving on?" Thesis, University of Wolverhampton, 1999. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.268095.
Full textAbstract:
As the higher education system expanded during the 1980s and early 1990s increasing numbers of mature women undertook the transition to graduate life. Such women also have a potentially prominent role as employees in the labour market of the mid-1990s in which the workforce is described as both feminised and "greying". Yet the dominant framework of research on the transition of graduates to the labour market, despite its recognition of the influence of structural factors of difference among graduates, has paid scant attention to the experiences of mature female graduates. This study begins the process of redressing that situation by adding both quantitative and qualitative data on the labour market outcomes of becoming a mature female graduate. The study's methodology is informed by feminist critiques of mainstream social research, and a central concern is to prioritise the perspectives of participants. The 137 women whose voices are represented in this dissertation entered first degree study on non-vocational courses, full or part-time, at or above the age of 21. They graduated from the University of Wolverhampton in 1994 and 1995. From their perspectives the transition entails considerably wider questions than those posed directly in relation to employment. Rather, the issues involve a complex interrelationship between structural and situational factors and the graduates' responses to these. Therefore the scope of the study incorporates questions of agency, understood as an aspect of identity. Escape, resilience, adaptation and marginality are core features of the findings connecting the three alternative forms of analysis presented. In these the graduates are first viewed collectively, then re-grouped in accordance with issues of age, gender, social class and ethnicity, and, finally, removed from categories in order to explore issues of identity and diversity. These analyses are then argued to be complementary perspectives that illustrate a possibility of moving beyond dichotomous approaches to understanding women's lives. The study concludes that the composite mature female graduate, Educated Rita, may be located and identified by addressing questions of structure and agency, similarity and difference, and that she considers the transition to be one in which she moves on

Languillon, Raphael. "Global Tokyo : ville mature, métropole renaissante." Thesis, Lyon 2, 2015. http://www.theses.fr/2015LYO22008/document.
Full textAbstract:
Tokyo est une ville mature qui se caractérise par une contraction de sa population active à la suite du vieillissement démographique et par une stagnation de ses indicateurs économiques (Produit Urbain Brut, prix immobiliers, stagflation). Néanmoins, malgré cet état, le tissu urbain de ses espaces centraux a été rénové à un rythme soutenu à partir du tournant des années 2000. Le dynamisme de la livraison de tours de grande hauteur contraste avec le contexte de maturité. La politique de renaissance urbaine mise en place en 2002 par le gouvernement central participe de la grande mutation des espaces centraux et péri‐centraux de la capitale japonaise. Elle permet d’articuler acteurs publics et privés autour d’opérations de rénovation urbaine de grande ampleur, qui concentrent les investissements dans des espaces précis. Ce travail de recherches doctorales analyse les impacts de la maturité urbaine sur la production immobilière et les recompositions spatiales du tissu tokyoïte, en interrogeant la mutation des stratégies des acteurs publics et privés impliqués dans la fabrique urbaine. La maturité est au cœur des questionnements : qu’est ce qu’une ville « mature » ? Comment continuer de créer de la richesse dans un contexte de quasi stagnation économique et démographique ? Cette thèse de doctorat aboutit à trois constats. La ville mature évolue peu à l’échelle macro, mais connaît d’intenses recompositions internes aux échelles méso et micro, traduisant une maximisation de la concurrence et de la compétition entre acteurs et entre territoires. Fruit de cette concurrence généralisée, Tokyo se recompose en points chauds qui concentrent les investissements et en points froids sur‐déprimés dans lesquels les pertes économiques et démographiques sont importantes. Afin de maintenir des taux de rentabilité intéressants pouvant garantir les opérations de renaissance urbaine, un nouveau régime d’accumulation du capital se met en place : un régime d’accumulation « dynamique ». Ce nouveau régime maximise les profits en accélérant la rotation du capital et des investissements immobiliers par le biais d’une obsolescence accélérée du bâti et par la mise en place d’une rotation cyclique des investissements par catégorie (bureau, Résidentiel de luxe, équipement, hôtellerie de luxe). La Contrepartie en est la contraction continue des espaces économiquement rentables ou intéressants les investisseurs privés. La Ville mature entraîne alors une contraction spatiale et temporelle des investissements et aboutit à des logiques de plus en plus concentrées et de plus en plus court‐termistesTokyo is a mature city characterized by two elements: its working population shrinks because of the demographic ageing, and its economic indicators stagnate (Growth Urban Product, real estate prices, stagflation). Nevertheless, in stead of this state, the urban frame of central spaces has been rapidly renewed since the turn of the 2000s. The dynamism of high rise building construction contrasts with the urban context. The urban renaissance policy initiated in 2002 by the central government encourages the great transformation of Tokyo’s central and sub‐central spaces. It allows to articulate public and private agents developing big urban renaissance projects, which concentrate investments in few urban spaces. This doctoral research work analyzes the impacts of urban maturity on real estate activities and on spatial restructurations of Tokyo’s urban frame. It investigates the strategy mutations of public and private agents involved in urban making. Maturity is the core of this PhD: What is a « mature » city? How to continue to create values in such a context of economic and demographic stagnation? This PhD thesis makes three conclusions. The mature city slightly changes at the macro scale, but faces intense internal recomposition at the meso and micro scales. It maximizes competition between agents and territories. As a result of this general competition, Tokyo is recomposed in hot spots, where are concentrated the investments, and in cold spots where economic and demographic losses are important. In order to maintain interessant rentability levels, a new capital accumulation regime appears: a « dynamic » capital accumulation regime. This new regime maximizes profits by speeding the rotation of capital and real estate investments speeding up the obsolescence of buildings and developing a cycle rotation of investments by category (commercial, residential, equipments, hotels). The counterpart is the shrinkage of economically profitable spaces. The mature city is therefore characterized by a spatial and temporal shrinkage of investments, and leads to more and more concentrated and more and more short- termist logics

Full textAbstract:
In this study, a new measure of mature religiosity was created. One hundred and fifty students were administered an 80 item scale based upon a consensus meaning of mature religiosity. The results of this administration were factor analyzed. Seven First Order Factors and two Second Order Factors emerged which could be adequately assessed by 50 of the 80 item. The revised 50 item scale was administered to 130 students. During the same administration, the students also responded to measures of personal maturity (Dogmatism Scale, Internal-External Locus of Control Scale, Social Desirability Scale) and other measures of mature religiosity (Intrinsic-Extrinsic Religious Orientation Scale, Interactional Scale from the Religious Life Inventory). One factor was found to overlap with the Intrinsic Religious Orientation Scale. It is also related to both the Interactional Scale and the Extrinsic Religious Orientation Scale, but the correlation was not enough to indicate duplication of those scales. The new scale was also found to be correlated with the Internal-External Locus of Control Scale, the Social Desirability Scale, and to be negatively correlated with the Dogmatism Scale.

Bruce, Richard Douglas. "Schubert's mature operas : an analytical study." Thesis, Durham University, 2003. http://etheses.dur.ac.uk/4050/.
Full textAbstract:
This thesis examines four of Franz Schubert's complete operas: Die Zwillingsbrűder D.647, Alfonso und Estrella D.732, Die Verschworenen D.787, and Fierrabras D.796. These works date from the period of 1818-1823, sometimes referred to as Schubert's 'years of crisis'. While this period saw many changes in the composer's personal situation, it is commonly thought that he underwent a process of creative re-evaluation during these years. This was also the period of Schubert's life during which he was most seriously engaged in writing music for the stage. Thus, I argue in this thesis that it is possible to understand these operas as key works within Schubert's stylistic development. Chapter 2 of this thesis studies Adorno's 1928 critique of Schubert and draws out common themes in critical writings about the composer to do with coherence, temporality and tone. These themes are then grounded in various different types of analytical observations about Schubert's emergent style. Chapter 3 examines selected numbers from the four mature operas. Through analysing these works, we find that Schubert's developing approach to form, rhythm, musical 'signs' and other structural devices is evident. Innovations in each of these fields are understood as responses to the various dramatic challenges offered by each of the libretti. Chapter 4 summarises the conclusions of our study of the operas and suggests some possibilities for interpretation of other works which are raised by these analyses.

Robertson, Janet. "Mature women and 'bulimia' : narrative perspectives." Thesis, University of Winchester, 2002. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.394057.
Full textAbstract:
This thesis focuses on the question 'what is bulimia?' A purposive sample of thirteen mature bulimic women were accessed via local newspapers. Multiple, in depth, nondirective interviews were carried out following a narrative story-telling approach. The women all told stories of how their bulimia started with a set of behaviours that provided a logical solution to a problem; the need to maintain control over body weight and shape in keeping with perceived norms of society. Following this they soon came to experience a sense of shame generated by a social gaze that views over-eating as indicative of a lack of personal control, and purging as disgusting. Their response was to maintain secrecy and attempt to find out more about bulimia. A social constructionist approach gave insights into the complex meaning-making processes that the women engage with. Popular material found in the public domain, constructed by health 'experts', functions to make up the dominant discourses of bulimia. Poststructuralist analyses focused on the relations of power and knowledge which allow certain powerful groups access to promote versions of 'bulimia' as truths. Foucault's poststructural approach goes beyond social constructionism by suggesting that discourse constitutes the individual and actually produces the 'bulimic'. Poststructural feminist perspectives, along with Foucault's concept of disciplinary power, provides understandings into how the female body as 'slim and beautiful' is used as a means by which women are regulated within Western societies. The dominant conceptualisation of bulimia as a condition that adolescent women predominantly suffer functioned to increase the shame that mature women experienced. Consequently, the analysis located narratives of resistance which involved rejections of dominant discourses. These resistant narratives challenge the notion of irrationality and uncontrollability that constructs both 'bulimia' and 'woman/femininity'. This in tum functions to challenge the shame and secrecy that surrounds 'bulimia'. These unique insights suggest that any definition of 'bulimia' is dependent upon the angle at which the 'lens' is focused or upon which the 'gaze' is fixed. There is not one, but many definitions of 'bulimia' that contradict, compete with and constrain each other. 'Bulimia' has been shown to be a multiple, fluid, and ever-changing phenomenon.

Full textAbstract:
The aim of the research was to assess the significance of higher education qualifications in the determination of the employment potential of mature students, having regard to other factors which may influence employment potential. The mature student was defined as being aged 25 and over on entry, attending a higher education establishment in pursuit of a qualification, within the parameters of the Department of Education and Science's definition of advanced further education. The research was based on the assumption that adults, in re-assessing their career development, sought to increase their stock of human capital and portfolio of educational credentials via the pursuit of a higher education qualification, in order to move upwards in the occupational hierarchy and across the boundary between the secondary and primary labour markets, whilst at the same time reducing the likelihood, and duration, of unemployment occurring. An initial survey of mature students indicated that 65% of respondents entered higher education for career purposes, with the percentage lower for females and declining with age. All students anticipated more problems than were actually experienced, whilst females anticipated more problems than males but actually experienced fewer. Furthermore, all students received greater benefits than they had anticipated and this was especially true of females. A follow-up survey produced results that showed some 65% of all students achieved employment and nearly 17% continued their studies, with more males achieving employment and more females continuing their studies. Such results formed the basis of the construction of a statistical model which enabled an indicator of the employment potential of mature students, given various characteristics,to be produced. The results indicated that employment potential declined after the age of 40 was reached, was much higher with six years of relevant experience, was very dependent on mobility and was highest for diplomates amongst the qualification category. Finally, the model was developed to incorporate local labour market conditions and highlighted the different probabilities of employment between regions and the 'general' probability of mature students with higher education qualifications achieving employment within Great Britain.

Full textAbstract:
Thesis (Ed.D.)--Boston UniversityThis research consisted of a case study of an active network for teacher inquiry. Specifically, I investigated how an organization dedicated to teacher inquiry had provided the structure, leadership, and resources to sustain, maintain, and expand the network. The group studied was the Mid-Ohio Writing Project, a teacher inquiry network affiliated with the National Writing Project. The Bolman & Deal (2003) framework for organization analysis, network theory, and small group dynamics provided frameworks for examining how the MOWP network had maintained itself since 1999. Data was collected through the use of largely participatory research methods, by means of both structured and unstructured approaches. Twenty-five members of the MOWP were observed, surveyed, interviewed, and invited to participate in focus groups involving visual representation exercises and discussion. The data were analyzed through categorical aggregation. Systems of open-coding, triangulation (among methods of analysis and means of data collection), and saturation (through extensive member checks, external audits, and progressive visual graphs) were used to increase the trustworthiness of the study and counteract possible reactive forces of participatory research. The findings of the study showed that practices of homogeneity, homophily, and insularity allowed the MOWP members the benefit of creating and protecting a safe haven in which to practice the scholarship of teaching. Simultaneously, efforts to preserve harmony discouraged attention to issues such as social justice and diversity, thus stunting recruitment and retention. It is recommended that similar groups create formal mission and vision statements, establish and maintain external funding resources from specific coalitions and stakeholders, develop a efficacious leadership structure to allow for a transparent connection between the network and larger umbrella organizations, streamline the number of groups in the network to produce meaningful work that will attract potential members and stakeholders, and use technology to link the group with the larger educational community.

Full textAbstract:
This thesis examines the experiences of mature women students who return to learning after a number of years out of the education system. It is a qualitative study based on loosely structured in-depth interviews with forty nine women attending college or university on a variety of courses in and around a northern city. The research, set within a theoretical framework of patriarchy, began as an exploration of the barriers which mature women meet when they return to education. These issues were very real in the women's lives, though they did not necessarily conceptualise them as barriers. In addition though, the appreciative, ethnographic style of research which I adopted enabled the women to tell their own stories, and totally unexpected data emerged. Around half of the students told me of painful experiences in their lives, either past or present. These stories became the central theme of the research and are presented in the main empirical chapter, largely in the women's own words. The central analytical question became 'what are the links, if any, between the women's experiences and their return to education?' I found from the research that this group of women were gaining far more from education than just paper qualifications. They talked of factors such as increasing confidence, an improved self-image, independence and fulfillment and I have made connections, which are drawn out throughout the main part of the thesis, between these factors, education and the trauma in the women's lives. The results were then used to examine the value of patriarchy as an illuminating framework for the women's experiences. In general, the women's stories are supportive of this perspective but they also highlight areas where there appears to be little research or discussion in the existing literature on patriarchy. These areas include psychological violence, the guilt feelings of the students, the control of women by other women and finally and perhaps most importantly, the agency which the women have shown in their determination to take some control over at least a part of their lives. Overall, it seems that whatever theft story, this group of students are using education as a vehicle to transform theft lives both socially and psychologically.

Full textAbstract:
An attempt has been made to chart the changes and development seen in the careers of a cohort of m/s over a period of three years. In earlier chapters it was shown that m/s were highly motivated and felt themselves to be deeply committed to the degree course. This continued to be an important factor that ensured that all but one m/s finished the course. The almost universal lack of confidence observed in this cohort at the beginning of the course may have been caused by the perception that m/s were going to be taking a role usually associated with much younger people and one which might appear to be inappropriate for an adult. Moreover,this new role would have to be learned and there seemed to be no guide lines to help. Most of these m/s had never met somebody of their own age embarking on such an undertaking; they had no "role-model" to follow. The question of role identity had not been forseen as a problem by those m/s starting a first degree course designed primarily for s/l, although many were apprehensive about their situation as adults in an activity which was largely associated with late adolescence - a period which they had already gone through. In order to cope with this problem the majority of m/s found it was necessary to keep the two roles they were playing separate - their m/s role at CCAT and the "adult" role in the home or away from CCAT. This separation was more marked in those who had family responsiblities who made up the majority in this cohort. The single students of both sexes were among the younger m/s and identified more easily with the s/l and the role of student. A certain embarrassment felt by some m/s at an apparent incongruity of being a middle-aged student was emphasised by the reactions of family and friends. Male students were made aware by outside social pressures that a drop in income was a considerable burden to bear. The worry of being able to keep up mortgage repayments, for example, was an ever-present strain. The hope of enhanced career opportunities at the end of the course helped to sustain them. The categorisation of respondents into those who were critical of the course, those who were enthusiastic about it and those who adapted to the demands made upon them, was developed. These groupings remained almost unchanged throughout the three years but the varying attitudes used did not seem to make any difference in how the m/s coped with the problems that they found. The critics hoped that some of their ideas for improving the course, which would help s/l too, might be put into practice. It was their initiative that led to some lecturers providing a "hand-out" to those who attend a lecture so that note-taking at the time is unnecessary. The enthusiasts kept up the level of their enthusiasm and the majority of theme hope to go onto further studies e.g. post-graduate teacher training or a higher degree. The adapters, who tended to be among those who were less conforming to the demands of tutors, found that the added confidence gained from the course enabled them to continue to study in the way that suited them best personally, and reinforced their own self-reliance in their ability to cope with the course. All m/s found it necessary to be well organised to be able to cope with the dual role of student and life outside the college, but felt that the effort was worth while for the benefits they received from the course. The great majority would advise prospective students to be aware of the time needed to get the most advantages and enjoyment out of the time spent as students at CCAT, but to go ahead if the opportunity presented itself. Those who had the support and encouragement of their families acknowledged the difference this made. Some said that it would have been impossible for them to have managed without it. The founding of the Mature Student Club could be seen as an effort on the part of m/s to reinforce the perception of themselves as separate and different from s/l. The mutual support and sharing of similar problems found within this organisation helped them to find an acceptable role within the student body. Staff also welcomed the presence of m/s for their evident commitment and high motivation. It was acknowledged that m/s helped to maintain a higher academic standard within the degree course because of their presence. The fears expressed by the Careers Officer at CCAT about the problems caused by lack of mobility for women when looking for work after the course had finished was not in evidence within the cohort itself. All eventually expected to build on the experience gained by being a degree student, although most were realistic in acknowledging that it might take longer than if they were geographically more mobile. The advantages of having survived a hard three years of work were thought to far outweigh the disadvantages of a diminished income and a complete absence of any spare time. The longitudinal approach of this research enabled a number of changes to be observed. Gradually, as they successfully negotiated the academic requirements of the course - the first year examinations, continuous assessment and essay assignments - confidence built up. By the time of the final examinations mature students felt that they knew what was expected of them and were able to rise to the necessary academic standard. The fact that only one student "dropped out" appeared to speak well for the admission procedures adopted by the staff at CCAT when dealing with mature students, i.e. they had chosen those that they perceived could "cope" with the academic and social demands of the course. Alternatively, it may suggest that most mature students successfully adapted to what, at first, may have been perceived as a personally challenging experience but which became, especially in the first year, a threatening, institutional environment. Familiarity with the institution and their fellow students helped to remove some of the apprehension that was initially felt and criticism of school leavers fell away. The majority reported an awareness of the benefits arising from the mix of ages and backgrounds found on the course and felt that they had a useful contribution to make.

Full textAbstract:
Bioretention cells (BRCs) are low-impact development stormwater management structures
that integrate water quantity and quality management. Although BRCs have a predicted design
life of about 25 years, most current research focuses on performance of cells less than two years
old. This project evaluated the effectiveness of a BRC installed in 2007 to treat a 0.16-ha
parking lot in Blacksburg, VA. After installation, this BRC was monitored for five months to
determine initial flow reduction and total suspended solids, and nutrient removal. By monitoring
for the same parameters, changes in cell performance since installation were quantified. ISCO
automated stormwater samplers collected inflow and outflow composite samples from the cell,
which were then analyzed for fecal indicator bacteria (total coliforms, E. coli, and enterococci),
total suspended solids (TSS), total nitrogen (TN), and total phosphorus (TP). To determine if
denitrification is occurring within the BRC, media samples taken throughout the cell were
analyzed using qPCR. The bioretention media was also sampled to quantify changes in media
nutrient content and particle size over the past seven years. Results indicate the bioretention
media has not accumulated nitrogen and phosphorus since installation, and that the BRC remains
effective at reducing flow volume and peak flow rates, as well as TSS, TN, TP, total coliforms,

Al-Isawi, R. H. "Urban wastewater treatment with mature constructed wetlands." Thesis, University of Salford, 2016. http://usir.salford.ac.uk/41423/.
Full textAbstract:
Despite the global acceptance for the application of vertical-flow constructed wetlands (VF CWs) as sustainable and cost-efficient technology in treating various types of wastewater, including urban wastewater, continuous loading of wetlands over time can lead to performance inefficiency and generate operational problems especially when high shock loads, such as petroleum hydrocarbon spills, are subjected to the system. Contamination with petroleum hydrocarbon compounds results in changing the structure, function and ecosystem service values of wetlands, which can eventually lead to clogging of the wetland substrate and affect the life time of the system. Sound knowledge of long-term performance in mature vertical-flow constructed wetlands linked with hydrocarbon treatment processes is needed to make guided judgments about the probable effects of a given suite of impacts and revise the management plans accordingly. A study was conducted to compare the impact of different design (aggregate size) and operational (contact time, rest time and chemical oxygen demand (COD) loading) variables on the long-term and seasonal performance of vertical-flow constructed wetland filters operated in tidal flow between June 2011 and March 2016. Ten different vertical-flow wetland systems were planted with Phragmites australis (Cav.) Trin. ex Steud. (Common Reed). Approximately 130 and 975 grams of diesel fuel (equivalent to 20 and 150 grams/litre, respectively) were each poured into four wetland filters on 26/09/2013 and 26/09/2014 respectively. Overall findings showed that the mature wetland system improved the water quality except for ortho-phosphate-phosphorus (PO₄-P), which reduced less over time. Findings also indicated that the wetland filter with the highest chemical oxygen demand (COD) loading but no diesel contamination performed the best in terms of COD and biochemical oxygen demand (BOD) removal. Filters contaminated by diesel performed worse in terms of COD and BOD but considerably better regarding nitrate-nitrogen removal. The removal efficiencies dropped for those filters impacted by the diesel spills. Seasonal analysis for water quality from different wetlands showed clear seasonal outflow concentration trends (low in summer) for COD, and nitrate-nitrogen (NO₃-N) while effluent BOD showed high treatment performance in winter. No clear seasonal trend for ammonia-nitrogen (NH₄-N), PO₄-P or suspended solids (SS) was noted. Serious clogging phenomena, impacting negatively on the treatment performance and the hydraulic conductivity, were not observed. The simulation model confirms the experimental findings that notable wetland clogging restricting the operation did not occur. Moreover, results showed that small aggregate diameter, low inflow COD load, and high contact and rest time were most efficient in reducing SS accumulation within the wetland filter bed. With regard to the treatment performance of the hydrocarbon contaminants, results indicated that all wetland systems had a relatively good performance in treating petroleum hydrocarbon compounds and the evaluation showed that all the hydrocarbon components were highly degraded and their concentrations were reduced in all treated effluents of wetland filters with time. This indicates that VF CW zones provide appropriate conditions for high treatment capacity of diesel compounds spilled with urban wastewater by a combination of processes taking place in the wetland filters, thus minimizing hydrocarbon compounds within the filter. A new experimental artificial ponds system, including: ponds with wastewater; ponds with wastewater and reeds; and ponds with wastewater, reeds and aeration, was operated in parallel with the mature experimental vertical-flow constructed wetland system, for the period between July 2015 and October 2015, to compare performance, design and operation variables between the two treatment technologies in the treatment of urban wastewater. Findings showed that highest COD and SS removals were observed for wetlands in comparison to ponds. Moreover, mature wetlands were better in removing NH₄-N and PO₄-P than ponds unless the ponds were aerated. Both systems were linked with medium to high levels of BOD removal. The aerated pond system demonstrated better treatment performance in terms of NH₄-N and PO₄-P. The NO₃-N concentration increased in the aerated ponds reflecting the high oxygen availability. Due to increasing water scarcity and droughts, which are key concerns worldwide, there is considerable interest in recycling various wastewater streams, such as treated urban wastewater, for irrigation in the agricultural sector. Recycling of effluents from various wetland filters (with/without diesel contamination) was assessed for the irrigation of chilli plants (De Cayenne; Capsicum annuum (Linnaeus) Longum Group ‘De Cayenne’) grown in a greenhouse environment. Concerning chilli fruit numbers, findings showed that the highest fruit yields for all wetland filters were associated with those that received inflow wastewater with a high loading rate, reflecting the high nutrient availability in treated wastewater, which is of obvious importance for yield production. Findings also indicated that wetlands without hydrocarbon contamination, with small aggregate size, low contact time, and low inflow loading rate provided high marketable yields (expressed in economic return). In comparison, chillies irrigated by filters with hydrocarbon contamination, small aggregate size, high contact time and high loading rate also resulted in high marketable yields of chillies, which pointed out the role of high contact time and high inflow load for better diesel degradation rates. The overall outcome of this research could considerably contribute to optimization of the design and development of long-term operation variables for constructed wetland technology particularly in petroleum industry applications. Statistically validated long-term data interpretation can particularly help the wetland modelling community and wetland managers to define, with insight into long-term and seasonal factors, removal processes for individual water quality parameters to maximize wetlands treatment performance.

Full textAbstract:
In mature forests, gains and losses of nitrogen may be dominated by the gaseous transformations, asymbiotic nitrogen fixation and biological denitrification. Both are reduction reactions and are affected by moisture conditions, temperature, pH, supply of organic carbon and the availability of mineral nitrogen.
Gaseous nitrogen inputs, due to asymbiotic nitrogen fixation, and outputs, due to biological denitrification were quantified for a mature coniferous forest in southwestern British Columbia. Forest floor material, mineral soil, decaying wood, foliage and bark were incubated in an atmosphere of 0.1 atm acetylene to allow the simultaneous measurement of N₂0 production by denitrifying bacteria and acetylene reduction by free-living bacteria and blue-green algae. Forest floor material accounted for 80% of a total annual input of 0.8 kg N ha⁻1 a⁻1. Relatively small amounts of nitrogen were fixed in mineral soil, decaying wood and foliage and no indication of nitrogen fixation activity in bark was detected. Traces of denitrification were found, but gaseous output of nitrogen was effectively 0.0 kg N ha⁻1 a⁻1. It is hypothesized that this forest may prevent nitrogen Joss by outcompeting other sinks for mineral nitrogen, thereby allowing a slow accretion of nitrogen by asymbiotic nitrogen fixation and bulk precipitation input.Forestry, Faculty of

Full textAbstract:
This dissertation is about treatment of the nonbiodegradable organic content of landfill leachate by chemical oxidation combined with biological treatment. It is divided into three parts. In the first part, ferrate was compared to Fenton's reagent for the purpose of removing non-biodegradable organic compounds from mature leachate. Oxidation conditions (time, pH, and dose) were optimized to yield maximum organic removal using two leachate samples from 20 and 12-year old solid waste cells. Results from this research demonstrated that ferrate and Fenton's reagent had similar optimum pH ranges (3-5), but different organic removal capacities, ranging from 54 to 79 % of initial leachate organic contents. An advantage of ferrate was that it was relatively effective over a wide pH range (Fenton's reagent lost its reactivity outside optimum pH range). Advantages associated with Fenton's reagent include a higher organic removal capacity, production of more oxidized organic compounds (measured as chemical oxygen demand/dissolved organic carbon), and production of more biodegradable byproducts (measured as 5-day biochemical oxygen demand/chemical oxygen demand). Finally, both treatments were found to oxidize larger molecules (>1000 dalton) and produce smaller molecules, as indicated by an increase in smaller molecule contribution to organic carbon. In part two, effects of Fenton's reagent treatment on biodegradability of three landfill leachates collected from a Florida landfill were evaluated using biochemical oxygen demand (BOD), biochemical methane potential (BMP), and tertamethylammonium hydroxide (TMAH) thermochemolysis gas chromatography/mass spectrometry (GC/MS). The hypothesis was that Fenton's reagent will remove refractory compounds that inhibit biodegradation and will produce smaller, more biodegradable organic molecules which will result in an increase in BOD and BMP values. Both BOD and BMP results demonstrated that Fenton's reagent treatment did not convert mature leachate to biodegradable leachate, as indicated by a low BOD5 expressed as C /dissolved organic carbon (DOC) ratio of almost 0.15 in treated samples and a low net methane production / theoretical methane potential (less than 0.15). Ultimate BOD only slightly increased. However the first-order BOD reaction rate increased by more than five fold, suggesting that Fenton's reagent removed refractory and inhibitory compounds. BMP results demonstrated that the ratio of CO2/CH4 produced during anaerobic biodegradation did not increase in treated leachate (compared to untreated), indicating that small biodegradable organic acids produced by oxidation were removed by coagulation promoted by Fenton's reagent. Finally, the TMAH thermochemolysis results showed that several of the refractory and inhibitory compounds were detected fewer times in treated samples and that carboxylic acids did not appear in treated samples. In the third part of this dissertation the application of flushing/Fenton's reagent oxidation to produce sustainable solid waste cells was evaluated. A treatment similar to pump and treat process utilizing Fenton's reagent on-site treated leachate combined with in-situ aeration was proposed. Treated leachate would be recycled to the landfill cell flushes releasable nonbiodegradable carbon from the cell and oxidizes it externally. This technique was demonstrated to have treatment cost and time benefits over other alternatives for producing completely stable solid waste cells such as anaerobic flushing and biological and/or mechanical pretreatment of solid waste (used in the EU).Ph.D.

Full textAbstract:
This is an ethnographic study of student teacher socialization located in a college of higher education. Drawing upon Lacey's research on teacher socialization, the study examines the processes of change and adaptation which a group of twenty-five mature women students underwent during their first year of a four year, B. Ed course. The research approach sits firmly within the qualitative paradigm and employs participant observation, interviews, life history methods and an interactionist perspective to further understanding about how mothers and wives learn to become students. A central feature of the study is the use of the concept of social strategy to explain change, particularly in relation to the way in which the women manage the demands of academic and family responsibilities. The construction of adaptive and coping strategies arise from a tightly interwoven relationship of life history, situational, institutional and structural features. Analyses of the progressive development of strategies revealed that becoming a student teacher was differentially experienced according to material resources, biographical and historical factors. The study offers a holistic analysis of student socialization in which the complexity of adaptation is revealed through the interrelationship of gender, identity, life course, strategies and the negotiation of change. An important part of this change is the emergence of a student teacher and academic identity, both of which are perceived as highly valued, new aspects of self, as well as being a significant part of student teacher socialization. In this hitherto under researched educational and sociological area of inquiry, the way in which biography and structure intersect with gender, reveals the uneasy blend of struggle, contestation, guilt and success which became a daily feature of the women's lives as they strove to reconcile the competing claims on their lives as mothers, wives and full-time students.

The objective of this thesis is to identify key factors that will produce further growth for NTT DoCoMo in Japan's mature mobile market. Since the early 1990s, the mobile phone market in Japan has grown rapidly, and competition for additional market share resulted in technological innovations like NTT DoCoMo's i-mode service to mobile carriers. Until recently, those innovations had leveraged the growth of the mobile phone industry. However, in 2004 the number of mobile phone subscribers exceeded 85 million and penetration rate reached 66.6%. Under such circumstances, the growth of the mobile carriers is gradually slowing. Moreover, there are threats which have the potential to change the current business model: mobile number portability, flat rate, new entrants, and globalization. In this thesis, I develop and organize frameworks that can be used by a company to produce further growth in a mature market by using traditional growth models. Then I analyze the sources for growth in mobile market and how the threats affect current dynamics in the mobile market. Finally I examine how the frameworks can work for NTT DoCoMo, and discuss the keys for growth in Japan's mature mobile market.

Shahabi, G. "Dynamic features of the mature retinal pigment epithelium." Thesis, University College London (University of London), 2012. http://discovery.ucl.ac.uk/1352450/.
Full textAbstract:
The retinal pigment epithelium (RPE) is a monolayer of cells that are vital for visual function and play a key role in the maintenance of the photoreceptors. Within RPE cells are melanin granules which absorb stray light and minimise scatter within the eye, therefore, protecting the RPE from damage. Albinos lack this protective capacity of melanin as a result of mutations of the tyrosinase gene. The first half of this thesis investigates heterogeneity within the RPE in both pigmentation phenotypes. Furthermore, the effect of ageing on the RPE is examined. Immunohistochemistry highlighted the molecular heterogeneity of the RPE and how this varies with pigmentation phenotype. In aged animals, SEM revealed abnormalities occurring within the photoreceptor outer segments of albinos, while ERGs and QRT-PCR illustrated that albinos show the signs of an age-related decline in visual function much sooner than pigmented animals. These studies revealed that in the outer retina, albinism is a progressive disease and not simply a congenital abnormality. The second half of this thesis investigates migration and proliferation of RPE cells in healthy pigmented animals. Using BrdU and DiI it was established that individual RPE cells have the ability to migrate. In addition, the effect of inducing lesions in different retinal locations was studied to determine whether this affects the response of RPE cells to the damaged area. The results conveyed that a single unilateral lesion in the RPE caused an upregulation of proliferating cells not only in the lasered eye, but also the contralateral unlasered eye in a quadrant specific manner. An additional experiment investigated the effect of treating rats with Glatiramer Acetate and found that it elevates levels of cell proliferation in the RPE of treated animals. Together, the data presented in this thesis demonstrate that the mature RPE is a dynamic heterogeneous epithelial cell layer.

Full textAbstract:
This research study investigated age as a predictor of success in the academic outcome and early professional performance of recent occupational therapy graduates. The study was divided into two parts. The analysis of age and academic performance in occupational therapy education initially provided a picture of mature student success when compared with the performance of younger students, but this finding was negated when the confounding variable of entry qualification was added to the analysis. The mature student data were strongly influenced by the superior academic performance of the students who had a previous degree on entry to occupational therapy education. When these degree-level entrants were removed from the age analysis, the academic performance of the remaining mature students did not differ significantly from that of the younger students. This result indicates that entry qualifications, in particular a previous degree, have a positive predictive affect on academic performance in occupational therapy education. The second part of the study investigated the impact of age on the early professional performance of recent occupational therapy graduates using a competency questionnaire adapted from the curriculum framework document for occupational therapy in the UK (COT, 1998). The hypotheses that age is a value-added factor in the early professional performance and level of threshold competence after graduation was partially upheld in the graduate self-ratings of competence but not in the employer ratings of new graduates in practice. No age differences were observed in the employer ratings of graduate abilities but academic performance at university was related to perceived levels of. competence. When graduates rated their self-perceived levels of competence, it was the mature graduates who consistently rated themselves as being more competent than their younger peers. The type of occupational therapy programme undertaken did not relate to either the employer or graduate ratings of competence. All respondents were provided with an opportunity to comment on the issue of professional competence. Mature students expressed high expectations of their professional competence yet were no different to all other new graduates in reporting stress when making the transition between being a student and qualified practitioner. A discrepancy in expectations of threshold competence was observed between the employer and the graduate comments.

Full textAbstract:
This thesis explores the experiences of mature students in higher education within the process of widening participation as part of the movement from an elite to a mass system. This process is viewed as a natural experiment in identity change as people who hitherto had no expectations of academic achievement are invited to see themselves in a very different light. The research was conducted in a Mixed Economy Group College in the north of England which specialises in 'return to study' provision for local students. The theoretical framework is existential phenomenological psychology which is deployed in describing the Tifeworld' of the participants, especially in relation to selfhood. Such an approach is relatively underplayed in this substantive area and as such augments other research in providing a different in-depth analysis. The resultant description traces a journey from a generally disempowered existential baseline through to an emerging self-identity which is perceived as profoundly transformed. In a relatively short period of their life participants rapidly encounter a legion of hitherto unknown experiences: engagement with academics and academic discourse, division into home and college self-identities, epiphanies of self development, and shifts in relationships. A new but inchoate self-identity is perceived through a range of novel encounters with people and ideas. This embryonic stage of a new self-identity is characterised by new knowledge and skills, a sense of confidence and empowerment, hitherto unknown aspirations, successes and status. Overall there is a perspectival shift in their view of the world and themselves within it. The journey however is a difficult one with existential dilemmas and contradictions constantly presenting themselves. The description employs the metaphor of 'existential pioneer' to describe the mode of living that characterises the participants' lived reality in tackling the trials and tribulations they encounter. Commentaries on self-identity in the contemporary world are considered apropos their relevance to the consciousness of participants engaging with education as an 'expert system'. The implications of the findings for an educational praxis and philosophy in relation to mature studentship in higher education are also considered. It is argued that for true widening participation to be effected, the full import of the mature student experience on entering and moving through the system should be given greater emphasis in all areas of the educational praxis. This means to acknowledge that the process of widening participation begins and does not end when the mature student enters higher education.

Full textAbstract:
Eukaryotic platelets are small cell fragments that are released into the bloodstream from megakaryocytes, and their production is initiated in the bone marrow. They are mainly involved in blood hemostasis and thrombus formation. The newly synthesized platelets are called reticulated platelets or young platelets. Zebrafish thrombocytes are equivalent to mammalian platelets and have similar characteristics and functions. Likewise, zebrafish has both young and mature thrombocytes. Only young thrombocytes as reticulated platelets are labeled with thiazole orange. Similarly, labeling zebrafish thrombocytes with a specific concentration of DiI-C18 showed two populations of thrombocytes (DiI+ and DiI-). Again, only young thrombocytes showed DiI+ labeling. The mechanism of selective labeling of young thrombocytes by is unknown. Furthermore, there is no zebrafish line where young and mature thrombocytes are differentially labeled with fluorescence proteins. Therefore, in this study, we identified and confirmed that the RFP labeled cells of Glofish were young thrombocytes. In addition, we found that myosin light chain 2 (MLC2) promoter is expressed in young thrombocytes. We also generated a transgenic zebrafish line, GloFli fish, where the young and mature thrombocytes are labeled with red and green fluorescence proteins respectively. Furthermore, this study showed a two-fold increase in glycerol-phospholipids (GP) in mature thrombocytes compared to young thrombocytes suggesting the lipid composition may be important for differential labeling. Therefore, we tested the liposomes prepared with different ratios of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) and observed that the lower amounts of PE favor the DiI-C18 labeling whereas higher concentrations of PC are less efficient. Also, in both PE and PC, increased concentrations of both resulted in decreased binding. These results are consistent with our observation that mature thrombocytes have higher concentrations GP and thus DiI-C18 may not bind to them efficiently compared to young thrombocytes.

Full textAbstract:
Improved prediction of forage quality and cow performance may enhance the nutritional management of beef cows. In two 12 mo trials, mature beef cows (n=136) grazing tall fescue pastures were used to compare estimates of forage quality and animal performance. Forage quality was estimated by proximate analysis of forage samples (FOR) or by near infrared reflectance spectroscopy of fecal samples (FNIR). Nutritional Balance Analyzer (NutBal), NutBalPro and 1996 NRC Nutrient Requirements of Beef Cattle (NRC) programs were used to predict animal performance. The objectives were to compare FOR and FNIR estimates of CP and TDN and to evaluate the accuracy of cow performance predicted by FNIR-NutBal, FNIR-NutBalPro and FOR-NRC systems. Initial BW, body condition score (BCS), hip height and breed were used to establish cow biotypes for prediction programs. Every 28 d, cow BW and BCS were measured and forage and fecal samples collected. Weather data, cow status and FOR or FNIR results were entered into NutBal, NutBalPro and NRC programs. Forage CP estimated by FNIR (CPFNIR) or FOR (CPFOR) were similar. In trials 1 and 2, correlation coefficients between CPFNIR and CPFOR were r = .24 and r = .43, respectively. Forage TDN estimated by FNIR was greater (P <.05) and lowly or moderately correlated to FOR estimates. Actual BW change between weigh periods (BWCHG) and ADG were similar to NRC predictions, but less (P<.0001) than predicted by NutBal or NutBalPro. The NutBal or NutBalPro mean BCS change between weigh periods (BCSCHG) were greater (P<.001) than NRC or Actual BCSCHG. Actual and NRC BCSCHG were similar (P>.2, trial 1) or tended (P<.1, trial 2) to be similar. Cow performance estimated by NRC was highly correlated to Actual. Absolute differences in animal performance were also investigated for each prediction program. In trials 1 and 2, NutBal and NutBalPro over-predicted BWCHG, ADG and BCSCHG by 40 kg, 1.25 kg/d and .75 BCS, respectively, compared to actual cow performance. It appears that FNIR is a promising predictor of forage CP but not TDN. Also, the FOR-NRC is a satisfactory predictor of cow performance.Master of Science

Full textAbstract:
This study explores the validity of geochemical paleoredox proxies in mature organic-rich shales. Classically, Fe-S-Corg ternary diagrams and C-S crossplots have been used to differentiate between oxic, dysoxic, and anoxic/euxinic conditions, but should be limited to immature shales due to the loss of organic carbon during thermal maturation. Trace metal proxies are also used to elucidate paleoredox conditions, but their stability in mature shales has yet to be assessed adequately. As it would be difficult to find a shale bed with an immature and post-mature end-member, that was deposited under assumedly invariant depositional conditions, a modified version of open-system hydrous pyrolysis (OSHP) was developed. The design of this apparatus allows for a small continuous flow of only liquid-phase water to be maintained throughout the entire artificial maturation experiment, with the intention of experimentally mimicking maturation in a sedimentary basin. Using the OSHP apparatus, the Anna Shale (Pennsylvanian age) was matured artificially at experimental temperatures ranging from 300 to 360℃ for up to 72 hours. These conditions resulted in increases in vitrinite reflectance from 0.47 to 1.83% Rr and Tmax from 425 to 520℃, indicating the immature shale was matured through the oil window and into the gas window. With increased maturity, the shale exhibits an approximate loss in mass of up to 20%, likely due to the liberation of hydrocarbons and the depletion of sulfur from 2.03 to ~0.1 wt. %. The intention of the OSHP design was to mimic maturation as would occur in a sedimentary basin. However, comparison of the inorganic geochemistry of the artificially matured shale to that of shales matured by normal burial maturation versus intrusive events suggests that, based on the significant depletion of sulfur (i.e., pyrite), the current design and run parameters better replicates the extreme heating conditions associated with intrusion of organic-rich rocks. Under these conditions, the loss of sulfur and carbon demonstrates that Fe-S-Corg ternary diagrams and C-S crossplots would no longer be valid as redox indicators. Furthermore, increases in the concentrations of Ni and Co by nearly an order of magnitude and a doubling of Cr and V contents from the unaltered to artificially matured shales cannot be explained by increases in relative abundance due to mass loss alone. It is possible that the 316-stainless steel used to construct the OSHP reactor body became unstable during artificial maturation experiments and acted as a contaminant source of TMs. Therefore, further investigation is required to establish whether different run parameters could more closely mimic normal burial conditions and to explore the use of different materials for the construction of the OSHP apparatus that would better maintain resistance to corrosion.

This thesis results from the collaborative projects between the LEQUIA-UdG group and Cespa (a company in charge of several landfill sites in Spain). The aim of the work was the development of a suitable alternative treatment for nitrogen removal from mature landfill leachates. The thesis presents the application of the anammox (anaerobic ammonium oxidation process) process to treat ammonium rich leachates as the second step of the PANAMMOX® process. The work deals with preliminary studies about the characteristics of the anammox process in a SBR, with special focus on the response of the biomass to nitrite exposure. The application of the anammox process with leachate was first studied in a lab-scale reactor, to test the effect of the leachate matrix on anammox biomass and its progressive adaptation. Finally, a start-up strategy is developed and applied for the successful start-up of a 400L anammox SBR in less than 6 months.Aquesta tesi és fruit de la col•laboració entre el grup LEQUIA-UdG i Cespa.

One major contributor is the inability to accurately predict ovulation in mares, which ovulate before the end of estrus, leaving much variability in coordinating insemination. A more efficient, less invasive method that could replace or reduce the need for constant teasing and ultrasonography to evaluate follicular activity is needed. In both dairy cattle and women, a change in body temperature has been shown to occur immediately prior to ovulation. Research on horses has been limited, although one study reported no useable relationship between body temperature and ovulation in mares (Ammons, 1989). The current study utilized thirty-eight mature cycling American Quarter Horse mares, and was conducted from March-August 2004. Each mare was implanted in the nuchal ligament with a microchip that can be used for identification purposes, but is also capable of reporting body temperature. Once an ovulatory follicle (>35mm) was detected using ultrasonography and the mare was exhibiting signs of estrus, the mare's follicle size and temperature were recorded approximately every six hours until ovulation. Not only was the temperature collected using the microchips, but the corresponding rectal temperature was also recorded using a digital thermometer. A significant effect (p<0.05) on body temperature was noted in relation to the presence or absence of an ovulatory follicle (>35mm) under different circumstances. When evaluating the rectal temperatures, no significant difference was found in temperature in relation to the presence or absence of a follicle. However, in the temperatures obtained using the microchip, temperature was higher (p<0.05) with the presence of a follicle of greater than 35mm. This may be due to the extreme sensitivity of the microchip implant and its ability to more closely reflect minute changes in body temperature.

Full textAbstract:
Amenity trees provide physical, social and economic benefits to people sharing their environment. To maintain the benefits that many people have come to expect of trees in their urban landscapes, a viable and dynamic tree population is required. To this end it is necessary to plant new trees or replace existing trees when they require removal. The challenge when replacing mature trees is not simply the process of planting a tree when one is removed, but of the continual replacement of the entire tree population in a planned and managed fashion. In urban landscapes this is not a natural process, and human intervention is required.

Leger, Ellen. "Mature students' perception of stress on returning to learn." Thesis, University of Leeds, 1996. http://etheses.whiterose.ac.uk/420/.
Full textAbstract:
In this thesis we present a theoretical model for mature students' perception of stress. The study examines the sources of institutional, dispositional and situational stress of students who are age thirty-to fifty-five. The research involved mature students in England (Yorkshire) and the United States of America (Minnesota). The stress inquiry is phenomenological action research with an interpretive and empirical approach. The design included in-depth interviews (N=60) and application of a questionnaire (N=382). The respondents were asked to describe 'what is it like to be a student at this time in his or her life. The data collected included perceptions of the student experience, institutional support, personal reactions to returning to learn, balancing family, work and study roles, primary sources of stress, change and transition experienced, evidence of psychological support, healthy and energy levels, and coping strategies. The study results indicate the primary sources of stress are managing roles, time management and institutional management of coursework. Students in the study did not report increased illness while returning to learn but did report fatigue. Significant gender-country differences include management of roles, workplace support, sources of funding, student status, and physical exercise as a coping strategy. Gender-country similarities include reactions to returning to learn, institutional support, response to change, psychological support, health and energy status, and personal status. The inquiry has implications for counselling mature students on stress and time management, instructional management of coursework, and recommendation for facility improvements to support efficient and effective learning. Education institutions have and will continue to experience increased mature student enrolment. This research provides specific information on the student experience with the institution, the student-self and the balancing of work, family, and study.

Full textAbstract:
While forage plays an important role in equine nutrition, little research has been conducted evaluating fiber utilization by young horses. Therefore, studies were conducted to compare in vivo digestibility and digesta passage in weanlings and mature horses (Exp 1) and yearlings and mature horses (Exp 2). All horses were fed forage-based diets at the same rate (on a metabolic BW basis; Exp 1: 67% alfalfa cubes, 33% concentrate; Exp 2: 75% timothy cubes, 25% concentrate). Ytterbium labeled hay and cobalt-ethylenediaminetetraacetic acid were used to estimate digesta mean retention time (MRT), while in vivo digestibility (DM, OM, and NDF) was measured using a total fecal collection method. Feed and water intake was similar between young and mature horses in both experiments. In Exp 1, there were no differences in digestibility or MRT due to age. The results suggested that weanling horses are capable of digesting a relatively high quality diet as efficiently as mature horses and that most of the development of the gastrointestinal tract occurs before 6 mo of age. In Exp 2, digestibility estimates were greater (P < 0.0311) for the yearlings than for the geldings. The increased digestive capacity of the yearlings was likely due to the longer MRT observed for the particulate phase in the yearlings (P = 0.0190). A third study was conducted to compare the microbial profiles of the feces of mares and foals. Fecal samples were collected from mare-foal pairs as the foal matured. The profiles of each pair, obtained using polymerase chain reaction-denaturing gradient gel electrophoresis, were compared and used to describe bacterial colonization in the foal. Mean similarity between mares and their foals on the day of parturition was low, but rapidly increased. Within 2 wk of parturition, similarity among mares and their foals was higher than among mature mares, suggesting that by 2 wk of age the bacterial species found in the foals’ gut are similar to those found in the mature horse. Collectively, the results from this series of experiments describe the early development of the foal’s digestive capacity.
