In this dissertation I quantify residential behavior response to interventions designed to reduce electricity demand at different periods of the day. In the first chapter, I examine the effect of information provision coupled with bimonthly billing, monthly billing, and in-home displays, as well as a time-of-use (TOU) pricing scheme to measure consumption over each month of the Irish Consumer Behavior Trial. I find that time-of-use pricing with real time usage information reduces electricity usage up to 8.7 percent during peak times at the start of the trial but the effect decays over the first three months and after three months the in-home display group is indistinguishable from the monthly treatment group. Monthly and bi-monthly billing treatments are not found to be statistically different from another. These findings suggest that increasing billing reports to the monthly level may be more cost effective for electricity generators who wish to decrease expenses and consumption, rather than providing in-home displays. In the following chapter, I examine the response of residential households after exposure to time of use tariffs at different hours of the day. I find that these treatments reduce electricity consumption during peak hours by almost four percent, significantly lowering demand. Within the model, I find evidence of overall conservation in electricity used. In addition, weekday peak reductions appear to carry over to the weekend when peak pricing is not present, suggesting changes in consumer habit. The final chapter of my dissertation imposes a system wide time of use plan to analyze the potential reduction in carbon emissions from load shifting based on the Ireland and Northern Single Electricity Market. I find that CO2 emissions savings are highest during the winter months when load demand is highest and dirtier power plants are scheduled to meet peak demand. TOU pricing allows for shifting in usage from peak usage to off peak usage and this shift in load can be met with cleaner and cheaper generated electricity from imports, high efficiency gas units, and hydro units.

The influence of information about trip time variability, personal benefits, or environmental harm from cars or public transportation on commuting mode choice (car or subway) is examined in an experimental study. In addition to these experimentally manipulated variables, the influence of prior attitudes towards the subway was verified. The sample is made up of habitual users of the car to travel to work (N = 220, age M = 37.4, SD = 8.1, 63.2% women). The results show that providing information about the advantages of public transportation, as well as prior attitudes towards the subway, decrease the preference, choice, and perceived control of car use. Of the experimentally manipulated variables, information about the variability of trip time had the greatest influence. These results highlight the importance of taking into account these variables to implement institutional campaigns to reduce car use as transportation mode.

Problem statement: Dietary fibre (DF) has been recognized as a major determinant for improvement of health. Hence the means of information through which people become aware of its benefits are crucial. Research questions: Where do you usually find information about dietary fibre? What means of communication do you consider the most appropriate to encourage the consumption of dietary fibre? Purpose of the study: This work aimed at studying the sources of information about dietary fibre, as a means to educate people about aspects related to healthy eating. Factors such as gender, level of education, living environment or country were evaluated as to their effect on the selection of sources and preferences.   Research Methods: Descriptive cross-sectional study by means of a questionnaire, applied to a non-probabilistic sample of 6010 participants from 10 countries in different continents (Europe, Africa and America), answered after informed consent by all participants. For the analysis were used several descriptive statistics tools, crosstabs and chi square test to assess the relations between some of the variables under study. Findings: Mostly the information about DF comes from the internet, but television is recognized as suitable. Differences were found between genders, levels of education, living environments and countries. The internet (preferred source), got highest scores for Hungary, urban areas, university education and female gender. The radio (least scored source) was preferred in Egypt, for men and with lower education (primary school). Conclusions: People get information through the internet due to easy access. However, it is to some extent a risk given the impossibility to control de information made public on the internet. The role of health centres and hospitals as well as schools should definitely be increased, as a responsible way to ensure correct information.

This qualitative study was aimed at investigating foreign language teachers’ attitudes toward use of information and communication technology (ICT) in their instruction. The insight was gained through the reported experience of ICT implementation by teachers, in what way and for which purpose they refer to use of technology, what kind of support and training they are provided with, and what beliefs they express about the influence of ICT implementation. This case study took place in one of the training schools in Finland. Five teachers participated in semi-structured interviews through a face-to-face approach. The findings demonstrated positive attitudes of teachers toward integration of ICT. The teachers shared their opinions about positive influence that ICT implementation has on both teaching and learning processes. However, they also pointed out the negative sides of ICT use: distraction of the students from usage of technology and technical problems causing frustration to the teachers. In addition, the responses revealed that the teachers are provided with adequate training aimed at enhancing their qualification which is provided with well-timed technology support and colleagues’ collaboration facilitating an efficient and smooth pace of the teaching process. According to the teachers’ opinions ICT integration in education appeared to have changed the role of the teacher. Due to different alterations in the field of ICT development teachers are required to upgrade their skills. The paper concludes with the limitations of the study and the recommendations for conducting further research.

We have long been critics of the creative work of philosophers and culture at the tender touch of his words, written or verbal, are both with the "hammer" that whoever owns the Ethics in writer-reader relationship is the first, called "comprehensive architect of the word" but inveterate dominant ideals of multiple anonymous.With this statement suggests that the second of this connection is nothing but a later, perhaps a "so and so" incognito benefits from its "home on earth", and who succeeds, after a long journey "cognitive "the privilege of reading. This old argument raised from ancient tradition, makes the reader a living subject-receptor but without providing the bulk of responsibility quantitative space offered by the marketing and consumption.Distrust of the concepts that attempt to establish a definition coldly detached from a bandage dressing, and the reader has not been imposed by the consumer society. In the sixteenth century came the paperback version, the books of Erasmus of Rotterdam were bestsellers in their time. The Praise of Folly and the political writings of Marthin Luther read at a time when the religious world was incorruptible, were read more than the Bible. Imitation of Christ by Thomas a Kempis in the 1300's, that is, before you discover Gutenberg printing circulated throughout Europe in the Latin language, and even in the inscrutable rock monasteries under his cassock, in the secret place of the monk carrying the book. Accepting that the reader is a result of the market, is to bring the book to reified object category and inapreciar history book.

A pressing challenge for the study of animal ethics in early modern literature is the very breadth of the category “animal,” which occludes the distinct ecological and economic roles of different species. Understanding the significance of deer to a hunter as distinct from the meaning of swine for a London pork vendor requires a historical investigation into humans’ ecological and cultural relationships with individual animals. For the constituents of England’s agricultural networks – shepherds, butchers, fishwives, eaters at tables high and low – animals matter differently. While recent scholarship on food and animal ethics often emphasizes ecological reciprocation, I insist that this mutualism is always out of balance, both across and within species lines. Focusing on drama by William Shakespeare, Ben Jonson, and the anonymous authors of late medieval biblical plays, my research investigates how sixteenth-century theaters use food animals to mediate and negotiate the complexities of a changing meat economy. On the English stage, playwrights use food animals to impress the ethico-political implications of land enclosure, forest emparkment, the search for new fisheries, and air and water pollution from urban slaughterhouses and markets. Concurrent developments in animal husbandry and theatrical production in the period thus led to new ideas about emplacement, embodiment, and the ethics of interspecies interdependence.

Despite a current emphasis in Romantic scholarship on intersubjectivity, this study suggests that we still have much to learn about how theories of intersubjectivity operate in Romantic-era writings that focus on the family—the most common vehicle for exploring relationships during the period. By investigating how sympathy, intimacy, and fidelity are treated in the works of Mary Hays, Felicia Hemans, and Mary Shelley, this dissertation discovers the presence of an “ethics of refusal” within women’s Romantic-era texts. Texts that promote an ethics of refusal, I argue, almost advocate for a particular mode of relating within a given model of the family as the key to more equitable social relations, but, then, they ultimately refuse to support any particular model. Although drawn towards models of relating that, at first, seem to offer explicit pathways towards a more ethical society, texts that promote an ethics of refusal ultimately reject any program of reform. Such rejection is not unaccountable, but stems from anxieties about appearing to dictate what is best for others when others are, in reality, other than the self. In this dissertation, I draw from feminist literary critiques that focus on ethics; genre-focused literary critiques; and studies of sympathy, intimacy, and fidelity that investigate modes of relating within the context of literary works and reader-textual relations. Psychoanalytic theory also plays an important role within my third chapter on Mary Shelley’s novel Falkner. Scholarship that investigates the dialectical nature of Romantic-era literature informs my entire project. Through theorizing and studying an ethics of refusal, we can more fully understand how intersubjective modes functioned in Romantic literature and discover a Romanticism uniquely committed to attempting to turn dialectical reasoning into a social practice.

Information entropy measured from acoustic emission (AE) waveforms is shown to be an indicator of fatigue damage in a high-strength aluminum alloy. Several tension-tension fatigue experiments were performed with dogbone samples of aluminum alloy, Al7075-T6, a commonly used material in aerospace structures. Unlike previous studies in which fatigue damage is simply measured based on visible crack growth, this work investigated fatigue damage prior to crack initiation through the use of instantaneous elastic modulus degradation. Three methods of measuring the AE information entropy, regarded as a direct measure of microstructural disorder, are proposed and compared with traditional damage-related AE features. Results show that one of the three entropy measurement methods appears to better assess damage than the traditional AE features, while the other two entropies have unique trends that can differentiate between small and large cracks.

Nascida para permitir que seus criadores possam atender suas próprias necessidades, a técnica científica sempre desempenhou papel significativo na civilização humana. Este é o contexto em que podemos vislumbrar o advento da tecnociência moderna, que tem contribuído significativamente para o incremento do controle humano sobre a natureza. Este estudo tem por objetivo analisar, sob o enfoque da bioética, reflexões sobre como a filosofia da ciência entende a neutralidade da ciência e sua convergência com a racionalidade epistêmica, bem como relacionar essas reflexões ao processo de tomada de decisões na administração da tecnociência. O estudo levantou dúvidas sobre a capacidade do conhecimento tecnocientífico para legitimar e justificar as decisões no âmbito dos sistemas de ciência e tecnologia nacionais, sinalizando assim a necessidade de promover ligação entre a auto-regulação tecnocientífico e hetero-regulação bioética. ______________________________________________________________________________ ABSTRACT

It is important for students to develop informed and realistic career aspirations to gain the most value from their university studies towards achieving their initial career goals. However developing students’ career aspirations, goals, and expectations is a complex and discipline-specific process. In Information Technology (IT) no clear career development framework is evident in the literature. Recent research in Australia argues that electronic portfolios are a useful way for students to develop, articulate and document career objectives to enhance their employability. IT students at Deakin engage in formal training and assessment with respect to developing their professional skills and career understandings. Currently electronic portfolios feature as a useful method for evidencing professional competencies for employability. Through a combined quantitative and qualitative analysis of 306 students’ articulated current career aspirations, qualitative analysis of 7 staff opinions of desired student career competencies, and a quantitative analysis of 28 students’ current work personality traits assessments (Work Personality Index), this work presents an analysis of the current state of IT students’ career development. The results indicate that while students reported short-term career aspirations, navigating to their long-term career goals is going to require addressing difficult barriers such as confidence (self-perception) and motivation. This research will influence a larger program-wide endeavour to build student career competencies for employability in IT at Deakin University.
