This study is undertaken in order to calibrate the continuous velocity logs using the comparision of synthetics and field records. The results refer to the following wells in Alberta. 1. Texaco Arrowhead B-76 60 25' 02"N, 122 59' 02" W 2. British American Morrin 7-3 Lsd 1, Section 3, Twp 31N, Rge 20 4M 3. Cancrude British American Champion 16-29 Lsd 16/ Section 29, Twp 14, Rge 24 W 4M The synthetic records were obtained using a linear filter model. To accomplish the synthesizing process in the laboratory, a magnetic tape function generator is used. The two-way time-depth curves are- plotted for these three wells. From these curves-the time intervals of continuous velocity logs were found in-error by 0.007 seconds to 0.0082 seconds. The possible errors in time scale of synthetic seismograms are discussed in Chapter IV. The comparision of synthetics with actual field seismograms recorded corresponding well locations and the main creteria for a "good match" and "poor match" are discussed. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

Group III nitrides are efficient light emitters. The modification of internal optoelectronic properties of these materials due to strain, external or internal electric field are an area of interest. Insertion of metal nanoparticles (MNPs) (Ag, Au etc) inside the V-shaped inverted hexagonal pits (IHP) of InGaN/GaN quantum wells (QWs) offers the potential of improving the light emission efficiencies. We have observed redshift and blueshift due to the Au MNPs and Ag MNPs respectively. This shift could be due to the electric field created by the MNPs through electrostatic image charge. We have studied the ultrafast carrier dynamics of carriers in hybrid InGaN/GaN QWs. The change in quantum confinement stark effect due to MNPs plays an important role for slow and fast carrier dynamics. We have also observed the image charge effect on the ultrafast differential transmission measurement due to the MNPs. We have studied the non-linear absorption spectroscopy of these materials. The QWs behave as a discharging of a nanocapacitor for the screening of the piezoelectric field due to the photo-excited carriers. We have separated out screening and excitonic bleaching components from the main differential absorption spectra of InGaN/GaN QWs.

Conducting a musical rehearsal is an inherently relational activity, requiring a mixture of musical and personal skills. Research and writing on the role of intentional reflection for educators, and subsequently conductors, has demonstrated the important role of reflection as a catalyst for growth. While many models of reflection including video reflection, journaling, and reflective dialogue have helped conductors and music educators gain self-awareness and experience growth, these models do not provide resources to deeply reflect upon the specific role of personality within the rehearsal setting. The Enneagram of Personality, in the form of the Riso-Hudson Enneagram Type Indicator (RHETI) was used in this study as a tool for reflecting on personality within the choral rehearsal. Three conductors completed the RHETI online, engaged in reflective conversation about individual personality traits, then watched videos of two recent choral rehearsals, verbally reflecting on the role of specific personality traits within the rehearsals. This document presents these three reflective journeys as case studies, ultimately exploring the usefulness of a tool like the Enneagram as an aid to personal and musical growth for conductors. Chapter One presents an overview of the literature on reflective practice, especially as it applies to education (broadly) and music education (specifically). Chapter Two introduces the Enneagram of Personality, summarizing its structure and core descriptions, as well as psychometric reliability and validity studies of the RHETI. Chapter Three describes the procedures used in the cases and the process developed for analyzing and interpreting the data. Chapters Four, Five, and Six contain the three cases, detailing each conductor’s interaction with the Enneagram within the prescribed reflective practice. Chapter Seven offers a cross-case analysis of the three cases and examines their implications for further research and future use of the Enneagram in musical practice.

Households in rural Ecuador face several challenges. One of them is the severe deprivation that reaches alarming percentages in the countryside. Unequal distribution and limited assets constrain households from improving their economic conditions. These factors induce households to overexploit natural resources. Poor households engage in a variety of livelihood strategies. Livelihood strategies are characterized by the allocation of assets (natural, physical, financial, public, social and human), income-earning activities (on farm, off farm), and outcomes (food, income, security). Together these determine the well-being attained by an individual or households. We used data collected by INIAP as part of the SANREM-CRSP project to identify livelihood strategies, their determinants, and well-being implications of adopting a particular livelihood. These data were from a comprehensive survey of 286 households collected during September and November, 2006. Livelihood strategies for the Chimbo watershed were identified using qualitative and quantitative methods. The methods provide similar results and identified four main livelihoods: households engaged in diversified activities, agricultural markets, non-farm activities, and agricultural wage work. Most households are engaged in agricultural markets followed by households in diversified activities. Households engaged in agricultural markets own higher amounts of natural and physical resources, while households engaged in non-farm activities have, on average, more human capital. Households participating in agricultural wage work are mainly from the down-stream watershed and posses less natural, physical and human assets. Factors influencing the selection of livelihood strategies were examined using a multinomial logit model. Variables such as access to irrigation, amount of farm surface and value of physical assets were statistically significant determinants of livelihood selection. Households with higher endowments of natural and physical assets are more likely to engage in agricultural markets and less likely to participate in non-farm activities. Secondary education tends to decrease participation in the agricultural sector while increasing engagement in non-farm activities. Several geographic variables like watershed location, altitude, and distance to rivers and cities are statistically significant determinants of livelihood strategies. The well-being associated with each livelihood strategy was estimated using least squares corrected for selection bias. Since participation in each livelihood is endogenously selected it was necessary to correct for selection. We use the Dubin- McFadden (1984) correction, based on the multinomial logit model. In our models of well-being few variables were statistically significant; this may be due to data limitations. Credit is statistically significant and has a positive effect on wellbeing. A similar positive effect is shown by education but the variable is not statistically significant. An odd result was found in the coefficient of irrigation access. This coefficient appears to decrease household well-being for those engaged in agricultural markets. This result is hard to explain, as we would expect that irrigation would be positively associated with well-being. The lack of access to water in irrigation systems in the region (noted by many respondents) might explain this negative effect. Most households that access irrigation do not have enough water, and access to irrigation does not provide the advantages that it might otherwise. The selection models were used to estimate the amount of well-being that households currently engaged in other livelihoods might receive if they selected a different livelihood. For example, what level of wellbeing would be attained by households currently engaged in agricultural markets if they instead engaged in non-farm activities. Results indicate that most households might achieve higher well-being if they engaged in non-farm activities. However households that want to engage in this sector require special skills or assets that are not easy to obtain; thus there are constraining barriers to diversification in the watershed. Several policy changes were simulated to determine their impacts on livelihood choice and household well-being. First a policy change that provides wider education to households in the region was assumed, with more education livelihood strategy selection moves towards the non-farm sector and away from agricultural wage work. These changes generate positive effects on household well-being. The second policy change was creating wider access to irrigation. This change moves livelihood strategies towards agricultural production and away from diversification and non-farm activities, and it had the effect of decreasing household well-being. This was unexpected but it is explained by the negative coefficient of irrigation access in the well-being model. These two policy changes were made to variables that are not statistically significant determinants in the well-being models but were highly significant determinants of livelihood strategies. The third and final policy was wider access to formal credit. Although credit is not a variable that affects the selection of livelihood strategies, it has an important effect on well-being. This policy change generates the highest increment in average well-being. However even though credit is available, if it is not used for productive purposes, it might represent an unnecessary cost for the households instead of being beneficial. / Master of Science / LTRA-3 (Watershed-based NRM for Small-scale Agriculture)

Yes / We put forward differences in the form of national identity across natives as a key mechanism explaining the sharp public divide on immigration issues. We show that inflows of migrants into local areas can be harmful for the self-reported well-being of natives, but this is only true for natives who self-identify with an ethnic form of national identity. On the other hand, we provide some evidence to suggest that immigration may be utility enhancing for natives with a civic form of national identity. We also show how differences in national identity significantly predicts voting preferences in the UK referendum on EU membership where concern with immigration issues was a salient factor. Drawing on identity economics, our proposed explanation is that for natives with an ethnic form of national identity, any positive economic benefits associated with immigration may not be enough to outweigh losses in identity based utility. / This work was supported by the Nuffield Foundation.

Divorce brings unprecedented changes. The prevalence of divorce today constitutes a need to thoroughly study the well-being of divorced peoples. This study used a multidimensional definition of well-being to study divorced peoples and other marital statuses. Physical, social, psychological, and socioeconomic well-being were used. This study hypothesized that the married and remarried have higher well-being than the never married who in turn have higher well-being than the divorced or separated. It was also hypothesized that some are pre-disposed to divorce. ANCOVA analysis was used to test these hypotheses in a sample of approximately 9,863 respondents from the NSFH study. Support was found for the hypothesis that the never married have higher well-being than the divorced or separated. This was true in all four aspect analyses. No support was found for the hypothesis that some are pre-disposed to divorce. Further, support was found for married and remarried having higher well-being than the divorced or separated and never married, but only in regards to psychological and socioeconomic well-being. Partial support was found for physical well-being. The divorced or separated had the lowest or close to lowest adjusted well-being mean of all marital statuses except in the social well-being analysis. Marital status and especially divorce does affect well-being.
