This dissertation examines Utah resident views of incentives and disincentives for use of OpenCourseWare (OCW) and how they fit into the theoretical framework of perceived innovation attributes established by Rogers. Rogers identified five categories of perceived innovation attributes, which include relative advantage, compatibility, complexity, trialability, and observability. A survey instrument was developed using attributes that emerged from a Delphi technique with input from experts in the OCW field. The survey instrument was sent to 753 (n = 753) random individuals between 18 and 64 years of age throughout Utah based on information obtained from Alseco Data Group, LLC. Results indicated that the greatest incentives for OCW use were (a) no cost for materials (M = 4.59, SD = .68), (b) having resources available at any time (M = 4.35, SD = .89), (c) pursuing in depth a topic that interests me (M = 4.24, SD = 0.93), (d) learning for personal knowledge or enjoyment (M = 4.22, SD = .93), and (e) materials in an OCW were fairly easy to access and find (M = 4.12, SD = .98). Results indicated that the greatest disincentives for OCW use were (a) there was no certificate or degree awarded (M = 3.28, SD = 1.54), (b) it did not cover my topic of interest in the depth I desired (M = 3.17, SD = 1.31), (c) lack of professional support provided by subject tutors or experts (M = 3.14, SD = 1.25), (d) lack of guidance provided by support specialists (M = 3.09, SD = 1.26), and (e) feeling the material was overwhelming (M = 3.06, SD = 1.31).

This thesis is a study of gender and organisation in Sri Lanka, a society of diverse cultural identities. The research question addresses factors related to women and men's orientations to work and the extent to which institutional factors, located in the broader societal context of Sri Lankan organisations, add explanatory power in analysis of the degree of job satisfaction and work perceptions. The thesis also investigates the relationship between organisational level attributes and the understanding of managers' work perceptions, as well as seeking variation at the institutional level. The main research instrument was a questionnaire, and quantitative data was generated from field surveys of 382 Sri Lankan male and female managers. The data is stratified randomly, forming a sample of top, middle and junior level managers. These managers belong to diverse Sri Lankan organisations in terms of size, ownership, and line of business. The findings illustrate that organisational level attributes have greater explanatory power in interpreting the work perceptions of male and female managers in Sri Lanka than do the institutional factors. However, qualitative interviews that were conducted reveal the salience of institutional factors to explain aspects of work perceptions. Organisational policies and recommendations that can be derived from this finding are elaborated in the conclusions. / Doctor of Philosophy (PhD)

It is a truism in contemporary understandings of semantics that there is no simple one-to-one correspondence between a word and its referent. As Wittgenstein has suggested, we can only know the meaning of a word by understanding the way it is used, and these uses are known often to be variable and highly context-dependent. / The issue of the variable meanings of terms is especially important when the term in question has assumed some centrality within a particular social domain, when its meanings are contested, and when the way the term is interpreted has a major bearing on subsequent social and institutional practices. In contemporary debates about the aims and purposes of higher education one such term is ‘critical thinking’. Whilst there is general unanimity in the higher education literature about the importance of ‘critical thinking’ as an educational ideal, there is surprisingly little agreement about what the term means exactly, as well as what exactly students should be taught in order to be appropriately critical in their field. / This thesis reports an empirical study which investigated conceptions of critical thinking as they are held by academics from a range of humanities disciplines: History, Philosophy, and Literary/Cultural Studies. The broad method used was a ‘textographic’ one, focusing both on how the concept of critical thinking was talked about by informants in interview, and also how it was constructed in a range of texts used by them in their teaching on undergraduate programs. / The study found a good deal of variation in the meaning of the term ‘critical’, not only between the three disciplines, but also within them. This variation was located in a number of areas: in the epistemic entities to which students needed to direct their thinking (e.g. textual vs. phenomenal entities), and in the various analytical modes they were required to adopt (e.g. evaluative vs. interpretative modes). The broad principle to be drawn from these findings is that the nature of one's thinking is indivisible from the object to which that thinking is directed. / The varieties of critical thinking found in the study provide some challenge to certain generic understandings of critical thinking, ones that have assumed increasing influence in higher education debates in recent years. The study concludes by suggesting that the teaching of critical thinking is likely to be more effective if handled within the context of students’ study in the disciplines, as opposed to a generic extra-disciplinary approach. It is also suggested that an important part of becoming a critical thinker in the academy is being able to recognise and to negotiate this variety of critical modes.

To better study frequency related effects such as attenuation and tuning, we developed a frequency dependent seismic reflection analysis. Comprehensive tests on full waveform synthetics and observations from the Teal South ocean bottom seismic (OBS) data set confirmed that normal moveout (NMO) stretch could distort both frequency and amplitude information severely in shallow events and far offset traces. In synthetic tests, our algorithm recovered amplitude and frequency information ac-curately. This simple but robust target oriented NMO stretch correction scheme can be used on top of an existing seismic processing flow for further analyses. By combining the NMO stretch correction, spectral decomposition, and crossplots of am-plitude versus offset (AVO) attributes, we tested the frequency dependent workflow over Teal south and Ursa field data sets for improved reservoir characterization. As expected from NMO stretch characteristics, low frequencies have been less affected while mid and high frequency ranges were affected considerably. In seismic attribute analysis, the AVO crossplots from spectrally decomposed prestack data confirmed the improved accuracy and effectiveness of our workflow in mid and high frequency regions. To overcome poor spectral decomposition results due to low signal to noise ratio (S/N) in the Teal South application, we also implemented a substack scheme that stacks adjacent traces to increase S/N ratio while reducing the amount of data to process and increasing the accuracy of the spectral decomposition step. Synthetic tests verified the effectiveness of this additional step. An application to the Ursa, Gulf of Mexico, deep water data set showed significant improvement in high frequency data while correcting biased low frequency information.

This study examines whether back stage information in services advertisements would significantly influence intangibility of services and consumers¡¦ perceived risk by experimental design, and whether ¡§back stage information-perceived risk¡¨ relation would mediated by intangibility. The researcher provides back stage information by print advertisements. The presentation of back stage information, the types of services, and the attributes of services are considered and included in research design to explore their roles in ¡§back stage information-intangibility-perceived risk¡¨ relation. The result shows that intangibility of services and consumers¡¦ perceived risk are significantly lower after consumers reading advertisements with back stage information contrast with those without back stage information. Intangibility has partial mediating effect on ¡§back stage information-perceived risk¡¨ relation. Though, presenting back stage information simultaneously by picture and text has a slightly better effect than by text alone, however, the difference is not significant. The type and attribute of services have no moderation on ¡§back stage information-perceived risk¡¨ and ¡§intangibility-perceived risk¡¨ relations respectively.

The success of the internet over last few decades has mainly depended on various infrastructure technologies to run distributed applications. Due to diversification and multi-provider nature of the internet, radical architectural improvements which require mutual agreement between infrastructure providers have become highly impractical. This escalating resistance towards the further growth has created a rising demand for new approaches to address this challenge. Network virtualization is regarded as a prominent solution to surmount these limitations. It decouples the conventional Internet service provider’s role into infrastructure provider (InP) and service provider (SP) and introduce a third player known as virtual network Provider (VNP) which creates virtual networks (VNs). Resource discovery aims to assist the VNP in selecting the best InP that has the best matching resources for a particular VN request. In the current literature, resource discovery focuses mainly on static attributes of network resources highlighting the fact that utilization on dynamic attributes imposes significant overhead on the network itself. In this thesis we propose a resource discovery approach that is capable of utilizing the dynamic resource attributes to enhance the resource discovery and increase the overall efficiency of VN creation. We realize that recourse discovery techniques should be fast and cost efficient, enough to not to impose any significant load. Hence our proposed scheme calculates aggregation values of the dynamic attributes of the substrate resources. By comparing aggregation values to VN requirements, a set of potential InPs is selected. The potential InPs satisfy basic VN embedding requirements. Moreover, we propose further enhancements to the dynamic attribute monitoring process using a vector based aggregation approach.

There is increasing pressure from animal rights organizations (AROs) on restaurant chains, food retailers, and meat processors to implement more stringent farm animal welfare (FAW) requirements for their suppliers. In the United States, AROs have recently initiated successful ballots to phase out confinement practices in several states. In Canada AROs have been pressuring both public and private sector stakeholders to improve FAW. Are FAW issues, however, paramount in the minds of Canadian consumers? Is the demand for more stringent FAW protocols primarily determined by a subset of consumers with very strong preferences or does it signal a more fundamental underlying change in consumer and societal preferences? Given the credence nature of FAW, who do consumers trust (i.e., government vs. private industry vs. independent third parties) in the market place for the provision of FAW quality assurances? What are the determinants of trust in these organizations for providing accurate information about animal welfare?<p> In order to answer these questions, a stated preference consumer survey encompassing FAW issues specific to the Canadian pork sector was tested on two samples of consumers in summer 2008, namely: a general population sample (GPS) across Canada and a sample of AROs members. Consumers participated in a purchase experiment where they had to chose between pork chops characterized by combinations of different levels of FAW attributes (i.e., housing system, gestation stalls, and use of antibiotics), quality verifying organization, and price. Multinomial Logit and Latent Class Logit Models were used to analyse the survey data.<p> Surprisingly, outdoor system does not seem to resonate well with Canadians, as both the GPS and the members of the AROs discounted this attribute. As expected, the AROs members have much stronger preferences for the other FAW attributes than have consumers in the GPS. Nevertheless, significant heterogeneity exists within consumer preferences. Five classes of consumers were identified in the GPS with respect to their preferences for FAW. At one end of the spectrum are the FAW sensitive consumers (12.3%) that have higher willingness-to-pay (WTP) for FAW, while at the other end of the spectrum Price Conscious consumers (18.3%) do not exhibit any WTP for FAW. The other three classes (69.4%) comprise respondents with mixed perceptions regarding FAW. Government and Third Party verification of FAW quality assurances had the strongest influence on consumers preferences in both samples. As well, scientific experts in FAW along with the above two organizations are the most credible in providing information about the welfare of pigs. The extent to which these organizations are knowledgeable about the welfare of pigs is the most important factor enhancing consumers trust. Results from this study suggest that there are potential marketing opportunities for pork chops sourced from pigs raised on farms where sows are kept in groups, and where credible quality assurances can be established, that private industry could consider. As well, the results suggest that consumers would derive benefits from the government taking a more active role with respect to validating FAW quality assurances.
