This thesis analyzes major microarray repositories and presents a metadata framework both to address the current issues and to promote the main operations such as knowledge discovery, sharing, integration, and exchange. The proposed framework is demonstrated in a case study on real data and can be used for other high throughput repositories in biomedical domain. Not only the number of microarray experimentation increases, but also the size and complexity of the results rise in response to biomedical inquiries. And, experiment results are significant when examined in a batch and placed in a biological context. There have been standardization initiatives on content, object model, exchange format, and ontology. However, they have proprietary information space. There are backlogs and the data cannot be exchanged among the repositories. There is a need for a format and data management standard at present.iv v We introduced a metadata framework to include metadata card and semantic nets to make the experiment results visible, understandable and usable. They are encoded in standard syntax encoding schemes and represented in XML/RDF. They can be integrated with other metadata cards, semantic nets and can be queried. They can be exchanged and shared. We demonstrated the performance and potential benefits with a case study on a microarray repository. This study does not replace any product on repositories. A metadata framework is required to manage such huge data. We state that the backlogs can be reduced, complex knowledge discovery queries and exchange of information can become possible with this metadata framework.

In this experiment I investigated the relationship between set-switching and transfer learning, both of which presumably invoke executive functioning (EF), which may in turn be correlated with intelligence. Set-switching was measured by a computerized version of the Wisconsin Card Sort Task. Another computer task was written to measure learning-transfer ability. The data indicate little correlation between the ability to transfer learning and the capacity for set-switching. That is, these abilities may draw from independent cognitive mechanisms. The major difference may be requirement to utilize previous learning in a new way in the learning-transfer task.

In this thesis, we characterize the proprietary active scanning algorithm of several wireless network interface cards. Our experiments are the first of its kind to observe the complete scanning process as the wireless network interface cards probe all the channels in the 2.4GHz spectrum. We discuss the: 1) correlation of channel popularity during active scanning and access point channel deployment popularity; 2) number of probe request frames statistics on each channel; 3) channel probe order; and 4) dwell time. The knowledge gained from characterizing wireless network interface cards is important for the following reasons: 1) it helps one understand how active scanning is implemented in different hardware and software; 2) it can be useful in identifying a wireless rogue host; 3) it can help implement Active Scanning in network simulators; and 4) it can radically influence research in the familiar fields like link-layer handovers and effective deployment of access points.

The concept and practice of watershed management have evolved since the early twentieth century and continue to change. Contemporary watershed management, as a means to improve environmental, social, and economic well-being, is generally accepted world-wide and is gaining popularity. Recognition of the ever-changing, complex, conflicting, and unpredictable nature of the forces that influence ecological and human systems has given rise to concepts and principles related to ecological or watershed health, sustainability, and good governance. Numerous terms have emerged to describe and explain contemporary watershed management processes that incorporate these concepts and principles, including ‘integrated’ and ‘sustainable’ watershed management. While there is growing consensus that integrated or sustainable watershed management should be practiced, there is little agreement on what these two terms mean and how they differ. The rational comprehensive or synoptic model is a widely-accepted normative framework to guide watershed management processes. This model presumes a ‘top-down’ linear, systematic, and logical sequence of steps characterized by complete knowledge of the issues and consequences of actions and dominated by rational decision making – circumstances that rarely happen in real life. Implementation gaps between theory and practice exist because of persistent and common challenges relating to complexity, conflict, uncertainty, and change in human and ecological systems. Failure to account for these factors has restricted the utility of this model for guiding watershed management processes, prompting questions about how the model might be adjusted to incorporate concepts and principles associated with watershed health, sustainability, and good governance. In response to the need to demonstrate progress towards watershed health and sustainability, a growing number of watershed organizations in Canada are pioneering the development of indicator-based assessment reports. The actual versus anticipated outcomes of watershed indicator reports and their existing and potential role in the watershed management process have not been systematically assessed or compared. A review of academic and professional literature and a mixed methods research approach comparing 13 case studies from 7 provinces across Canada were used to explore these knowledge gaps. A more in-depth investigation of two of the case studies, the Fraser Basin Council and the Humber Watershed Alliance, was also completed. Contextual factors influencing the practice of watershed management and the process used for developing watershed report cards are identified through an analysis of available documents. This information is supplemented with opinions gathered from 109 in-depth and semi-structured interviews/questionnaires. In addition, informants provided viewpoints regarding the usefulness, effectiveness, benefits, and value of watershed report cards, along with ideas about how they can be improved. This study concludes that while sustainable watershed management (SWM) and integrated watershed management (IWM) are closely aligned concepts, the distinguishing factor is scope. The primary goal of SWM is environmental, social, and economic sustainability within a watershed unit, whereas the central focus of IWM is the protection and/or restoration of water and land resources within a watershed to sustain human well-being. In Canada, IWM rather than SWM is generally pursued. Nevertheless, sustainability is an ultimate goal of IWM. Sustainability principles are acknowledged, valued, and applied. This study concludes that IWM can play a significant role in supporting a broad sustainability agenda. This study contributes to a growing body of knowledge seeking to enrich the theory of watershed management and improve and streamline practice. To improve the utility of the rational comprehensive model for guiding contemporary watershed management, modifications are presented which include separate phases for visioning and learning and couch the process within an overall conceptual framework that balances management, research, and monitoring activities. These adjustments reflect the concepts of integration, collaboration, and shared learning and acknowledge the shift away from ‘command and control’ bureaucratic processes to collaborative ‘middle ground’ polycentric governance structures. Rather than focusing strictly on a sequence of steps and a prescribed process, the consideration of a series of context-specific questions is advocated to help scope and streamline processes to match stakeholder capacity, address issues of greatest concern, and sustain interest and enthusiasm. However, concerted effort is required to counteract competing and entrenched socio-political and economic doctrines and traditions. Monitoring, evaluating, and reporting are key components in the IWM process. Study findings reveal that watershed report cards in Canada are a fledgling tool and no standard approach exists. Each case-study watershed organization has a unique approach to selecting, organizing, and presenting indicators. As a result, report card styles and formats vary. Despite a general consensus that watershed report cards are worthwhile, expectations often exceed outcomes, and common traits which challenge their effectiveness exist. The usefulness and effectiveness of watershed report cards are hampered by several common shortfalls: (1) universal lack of consistent, spatially-specific, and timely data, (2) inconsistent measures and indicators between successive watershed reports, (3) ambiguous or non-existent goals, objectives, targets, and benchmarks, and (4) messages that are unclear, difficult to understand, or fail to resonate with the target audiences. The ‘lessons learned’ from an assessment of the attributes and perceived benefits of watershed report cards parallel those discovered for community indicator initiatives. Building on this research, recommendations for improvement include (1) focus on stakeholder issues of prime concern, (2) use consistent measures and indicators, (3) limit the number of indicators and simplify report card styles and formats, (4) select spatially explicit, temporally relevant, and science-based indicators and measures, (5) explain and illustrate major cause-effect linkages, (6) use the report card process to build a constituency of support, (7) incorporate marketing and outreach activities, and (8) introduce performance measures to assess efficiency and how well collective practice demonstrates sustainability principles. This study concludes that opportunities exist for improving watershed report cards and boosting their multi-purpose role as a predominant planning, assessment, advocacy, communication, learning, and research tool in support of IWM, and ultimately, sustainability.

This study intends to investigate the role of credit card commercials in the integration of credit cards to the Turkish society and how this integration has affected the concept of consumption in Turkey. While presenting credit cards to the society, commercials establish certain kinds of relationships between people and credit cards, as well as between people and the other commodities in the market. In this respect, they attempt to rationalize the use of credit cards and to get social approval in order to widen credit card spending among society. Exploring the ways commercials attempt to lay the ground for credit card purchasing, the research focuses on the inversion of established values in the Turkish society related with consumption. In this frame, 210 credit card commercials broadcasted on TV over an eight year period are selected and examined through the combined semiological and content analysis. The outcome of the research unveils the role of credit card commercials in the transformation of the idea of consumption in Turkey. In this sense, research demonstrates the socio-cultural affect of commercials in the society.

The aim of this thesis is to identify factors that affect the university students&rsquo / acceptance of multi-purpose Smart Cards. The findings of this study will be beneficial to facilitate the use of Smart-Card enabled system both n universities and in other institutions which either have these systems in use or plan to invest on these systems in the future. The research methodology employed within this study is based on quantitative methods. A survey instrument comprising 51 5-point Likert-type questions has been developed and applied to 207 university Middle East Technical University students. The data collected has been analyzed using Exploratory Factor Analysis to categorize factors having items. According to analysis results, the data classified under 5 factors / Perceived Usefulness, Perceived Ease of Use, Behavioral Intention, Anxiety, and Technological Complexity. Then, the relations between these 5 factors identified and a measurement model was created. For assessing the proposed model Discriminant and Convergent Validity scores were calculated by Confirmatory Factor Analysis. Then, Structural Equation Modeling was conducted with Partial Least Squares for validating the model&rsquo / s estimated influence. The study has shown that the main Technology Acceptance Model constructs fit for determining the university students&rsquo / intention of Smart Card usage except for Perceived Ease of Use over Behavioral Intention. Moreover, study showed that Anxiety and Technological Complexity were the external factors that have effect on willingness of using multi-purpose Smart Cards. If students have Anxiety, this affects their perception of easiness of the system and it has negative indirect effect on the perceived usefulness and direct effect on intention. Technological Complexity is another factor which has direct affect on the perception of easiness and usefulness and intention.
